Dear Shareholder:
    
     You are cordially invited to attend a Special Meeting of Shareholders of
Louisiana Independent Physicians Association, Inc. ("LIPA"), to be held at
Glynnwood, 6230 Bluebonnet Boulevard, Baton Rouge, Louisiana 70809, on May 30,
1996, at 6:30 p.m. local time. A notice of the Special Meeting, Proxy
Statement/Prospectus and proxy card containing information about the matters to
be acted upon are enclosed. All holders of LIPA's outstanding shares of Common
Stock ("LIPA Common Stock"), as of April 30, 1996 (the "Record Date"), will be
entitled to notice of and to vote at the Special Meeting and any postponement or
adjournment thereof.     
    
     At the Special Meeting, you will be asked to consider and to vote upon a
proposal to approve and adopt an Agreement and Plan of Merger (the "Merger
Agreement"), dated as of January 16, 1996, among LIPA, United HealthCare
Corporation ("United") and UHC Gold Acquisition, Inc., a direct, wholly owned
subsidiary of United ("United Sub"), as amended, pursuant to which LIPA would be
merged with and into United Sub (the "Merger"). If the Merger Agreement is
approved and adopted and the Merger becomes effective, each outstanding share of
LIPA Common Stock, other than LIPA Common Stock as to which dissenters' rights
have been duly demanded as permitted under Louisiana law and not withdrawn or
lost (the "Dissenting Stock"), will be converted into the right to receive a pro
rata allotment of an aggregate number of shares of common stock, $.01 par value,
of United (the "United Common Stock"), equal to $50,000,000 divided by the
average closing price of United Common Stock on the New York Stock Exchange (the
"NYSE") for the ten trading days ending with and including the second trading
day preceding the closing of the Merger (the "Average Stock Price"); provided,
however, that the number of shares issuable in the Merger will be fixed at (1)
938,692 if the Average Stock Price is at least $49.2707 but less than $53.2656,
or (2) 730,093 if the Average Stock Price is more than $68.4844 but not more
than $73.0500. If the Average Stock Price is more than $73.0500, the number of
shares issuable in the Merger will be (1) $53,750,000 divided by (2) the Average
Stock Price. If the Average Stock Price is less than $49.2707, the number of
shares issuable in the Merger will be (1) $46,250,000 divided by (2) the Average
Stock Price.     
    
     Assuming that the Average Stock Price equals the closing price per share of
United Common Stock on the NYSE on April 26, 1996, or $58.3750, and that the
number of shares of LIPA Common Stock outstanding at the Effective Time equals
the 418 shares of LIPA Common Stock outstanding as of the Record Date, each
outstanding share of LIPA Common Stock would be converted into the right to
receive approximately 2,049 shares of United Common Stock, having a market value
of approximately $119,600.    

     The Merger is subject to the satisfaction of a number of conditions,
including approval of the Merger Agreement and the Merger by the requisite vote
of LIPA's shareholders. Pursuant to the Merger Agreement, the letter of
transmittal that the shareholders of LIPA must submit in order to receive their
shares of United Common Stock will contain a waiver. The waiver, the form of
which is Exhibit 2.02(b) to the Merger Agreement, will release United and other
parties from all claims relating to the provision prior to January 1, 1995 by
the shareholder of services to Community Health Network of
<PAGE>
         
Page 2
 
Louisiana, Inc., a Louisiana corporation, Louisiana Health Management Company, a
Louisiana general partnership, and Louisiana Health Partners, Inc., a Louisiana
corporation (collectively, the "Community Health Entities").
    
     In addition to the receipt of United Common Stock, at the effective time of
the Merger each share of LIPA Common Stock outstanding, other than Dissenting
Stock, will receive the right (the "Contingent Payment Right") to receive
contingent cash payments, net of any amount to which United is entitled pursuant
to the indemnification provisions of the Merger Agreement. The aggregate amount
of such payments (each, an "Earn-Out") will be determined by reference to the
audited combined net income of the Community Health Entities and MetraHealth
Care of Louisiana, Inc., a wholly-owned subsidiary of United, after taking into
account certain adjustments, including adding back the after-tax effect of
interest expenses, acquisition expenses, expenses relating to matters for which
United is indemnified under the Merger Agreement, and certain operating expenses
that exceed 10% of specified premium revenues (the "Adjusted Net Income"). For
the period January 1, 1996 to December 31, 1996, the Earn-Out will equal the
amount by which Adjusted Net Income exceeds $10.0 million, multiplied by 6.3.
For the period January 1, 1997 to December 31, 1997, the Earn-Out will equal the
amount by which Adjusted Net Income exceeds $16.5 million, multiplied by 4.5. In
no case, however, can the aggregate of the two Earn-Outs exceed $35.0 million.
The amount payable to each holder of a Contingent Payment Right will be equal to
the Earn-Out for the applicable year divided by the number of Contingent Payment
Rights outstanding at the time payment is due.     

     Details of the proposed Merger and other important information are set
forth in the accompanying Proxy Statement/Prospectus, which you are urged to
read carefully.

     Your Board of Directors has carefully reviewed and considered the terms and
conditions of the proposed Merger. In addition, your Board of Directors has
received the opinion of its financial advisor, The Robinson-Humphrey Company,
Inc., that the consideration to be received by the holders of LIPA Common Stock
pursuant to the Merger is fair to such shareholders from a financial point of
view.

     YOUR BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE MERGER AND RECOMMENDS
THAT YOU VOTE FOR APPROVAL AND ADOPTION OF THE MERGER AGREEMENT.
    
     Whether or not you plan to attend the Special Meeting, please complete,
sign and date the accompanying proxy card and return it in the enclosed prepaid
envelope. If you attend the Special Meeting, you may revoke such proxy and vote
in person if you wish, even if you have previously returned your proxy card. If
you do not attend the Special Meeting, you may still revoke such proxy at any
time prior to the Special Meeting by providing written notice of such revocation
to Charles Raborn, M.D., Secretary of LIPA. Your prompt cooperation will be
greatly appreciated.     


                                           Very truly yours,
                                           V. Lynn McCord, M.D.

Statement/Prospectus. This summary is not intended to be complete and is
qualified in all respects by the more detailed information included in this
Proxy Statement/Prospectus and its Exhibits. Shareholders are urged to read

Inc., respectively, and, where the context so requires, to their respective
subsidiaries. United has supplied all information concerning United and its
subsidiaries included herein, certain information concerning the subsidiaries of
LIPA and information about LIPA on a consolidated basis, and LIPA has supplied
all information herein concerning LIPA on an unconsolidated basis.

                                    GENERAL
    
     This Proxy Statement/Prospectus relates to the proposed merger (the
"Merger") of Louisiana Independent Physicians Association, Inc., a Louisiana
corporation ("LIPA"), and UHC Gold Acquisition, Inc., a Louisiana corporation
("United Sub") and a direct, wholly owned subsidiary of United HealthCare
Corporation, a Minnesota corporation ("United"), pursuant to an Agreement and
Plan of Merger, dated as of January 16, 1996 (the "Merger Agreement"), among
LIPA, United and United Sub, as amended, a copy of which is attached to this
Proxy Statement/Prospectus as Exhibit A. As a result of the Merger, among other
things, (1) LIPA will be merged with and into United Sub (the "Merger"), (2)
each outstanding share of common stock, no par value, of LIPA ("LIPA Common
Stock"), other than LIPA Common Stock as to which dissenters' rights have been
duly demanded as permitted under Louisiana law and not withdrawn or lost (the

$53,750,000, and (3) each share of LIPA Common Stock outstanding, other than
Dissenting Stock, will receive one right (the "Contingent Payment Right") to
receive contingent cash payments with a value of between $0 and approximately
$84,000 per share.     
    
     The close of business on April 30, 1996, has been fixed as the record date
for the determination of the shareholders of LIPA entitled to notice of and to
vote at the Special Meeting and any adjournment or postponement thereof.

     United is a national leader in offering health care coverage and related
services through a broad continuum of products and services. United served over
40 million covered lives at December 31, 1995. United's products and services
utilize a number of core capabilities, including medical information management,
health care delivery management, health benefit administration, risk assessment
and pricing, health benefit design and provider contracting and risk sharing.
With these capabilities, United is able to provide comprehensive managed care
services, such as health maintenance organization ("HMO"), insurance and self-
funded health care coverage products, as well as unbundled health care
management and cost containment products such as mental health and

"Average Stock Price"); provided, however, that the number of shares issuable in
the Merger will be fixed at (1) 938,692 if the Average Stock Price is at least
$49.2707 but less than $53.2656, or (2) 730,093 if the Average Stock Price is
more than $68.4844 but not more than $73.0500. If the Average Stock Price is
more than $73.0500, the number of shares issuable in the Merger will be (1)
$53,750,000 divided by (2) the Average Stock Price. If the Average Stock Price
is less than $49.2707, the number of shares issuable in the Merger will be (1)
$46,250,000 divided by (2) the Average Stock Price. The Merger is subject to the
satisfaction of a number of conditions, including, among others, approval of the
Merger Agreement and the Merger by the requisite vote of LIPA's shareholders.
    
     Assuming that the Average Stock Price equals the closing price per share of
United Common Stock on the NYSE on April 26, 1996, or $58.3750, and that the
number of shares of LIPA Common Stock outstanding at the Effective Time equals
the 418 shares of LIPA Common Stock outstanding as of the Record Date, each
outstanding share of LIPA Common Stock would be converted into the right to
receive approximately 2,049 shares of United Common Stock (the "Assumed Exchange
Ratio"), having a market value of approximately $119,600.     

     Fractional shares of United Common Stock will not be issued in connection
with the Merger. Shareholders of LIPA otherwise entitled to fractional shares of
United Common Stock will be paid cash in lieu of such fractional shares
determined as described herein under "THE MERGER--Fractional Shares."

                                       9

     In addition to United Common Stock, at the effective time of the Merger
each share of LIPA Common Stock outstanding, other than Dissenting Stock, will
receive one Contingent Payment Right to receive two contingent cash payments,
net of any amount to which United is entitled pursuant to the indemnification
provisions of the Merger Agreement. The aggregate amount of such payments (each
of the two aggregate payments, an "Earn-Out") will be determined by reference to
the audited net income of Community Health Network of Louisiana, Inc., a
Louisiana corporation ("CHN"), Louisiana Health Management Company, a Louisiana
general partnership ("LHMC"), Louisiana Health Partners, Inc., a Louisiana
corporation ("LHP," and together with CHN and LHMC, the "Community Health
Entities"), and MetraHealth Care of Louisiana, Inc. ("MetraHealth Louisiana"), a
wholly-owned subsidiary of United, after taking into account certain
adjustments, including adding back the after-tax effect of interest expenses,
acquisition expenses, expenses relating to matters for which United is
indemnified under the Merger Agreement, and certain operating expenses that
exceed 10% of specified premium revenues (the "Adjusted Net Income"). For the
period January 1, 1996 to December 31, 1996, the Earn-Out will equal the amount
by which Adjusted Net Income exceeds $10.0 million, multiplied by 6.3. For the
period January 1, 1997 to December 31, 1997, the Earn-Out will equal the amount
by which Adjusted Net Income exceeds $16.5 million, multiplied by 4.5. In no
case, however, can the aggregate of the two Earn-Outs exceed $35.0 million (or
approximately $84,000 per share of LIPA Common Stock). The amount payable to
each holder of a Contingent Payment Right will be equal to the Earn-Out for the
applicable year divided by the number of Contingent Payment Rights outstanding
at the time payment is due. See "THE MERGER--Contingent Payment Rights."     

     PROCEDURES FOR EXCHANGE OF CERTIFICATES, WAIVER OF CLAIMS AND CONTINGENT
     PAYMENT RIGHTS

     Promptly after the Effective Time, a letter of transmittal and instructions
for surrendering stock certificates evidencing shares of LIPA Common Stock will
be mailed to each holder of LIPA Common Stock for use in exchanging such
holder's stock certificates for certificates evidencing shares of United Common
Stock and for receiving cash in lieu of fractional shares and any dividends or
other distributions to which such holder is entitled as a result of the Merger.
Upon surrender of a certificate or certificate representing outstanding shares
of LIPA Common Stock (the "Certificates") for cancellation to the Exchange Agent
together with a letter of transmittal, duly executed, including a waiver of
claims arising from the provision of services by the shareholder to the
Community Health Entities prior to January 1, 1995, the form of which is Exhibit
2.02(b) to the Merger Agreement (the "Waiver"), and any other documents as may
be required pursuant to such instructions, the holder of the Certificate will be
entitled to receive in exchange therefor a certificate representing that number
of whole shares of United Common Stock which the holder has received in respect
of the shares of LIPA Common Stock formerly represented by the Certificate, cash
in lieu of fractional shares of United Common Stock (after taking into account
all shares of LIPA Common Stock then held by the holder) and any dividends or
other distributions to which the holder is entitled pursuant to the Merger
Agreement, and the Certificate so surrendered will forthwith be canceled. The
Waiver is a release by a LIPA shareholder of United, LIPA, the Community Health
Entities, and United's subsidiaries, officers, directors, employees and agents
from all claims relating to the provision by the shareholder of services to the
Community Health Entities prior to January 1, 1995, including any claims that
may exist in connection with certain withholding arrangements between providers
and the Community Health Entities. The Waiver functions as an alternative to a
representation, with related indemnification provisions, in the Merger Agreement
by LIPA that it had settled all outstanding claims concerning these withholding
arrangements. United required this more effective form of protection as a
condition to the acceptance of its final offer of merger terms. See "THE 
MERGER--Procedures for Exchange of Certificates and Waiver of Claims" and "THE
MERGER--Background of the Merger." SHAREHOLDERS SHOULD NOT SEND ANY STOCK
CERTIFICATES WITH THEIR PROXY CARDS. See "THE MERGER--Procedures for Exchange of
Certificates and Waiver of Claims."
    
     United will deliver a calculation of the Earn-Out for each of the years
ended December 31, 1996 and December 31, 1997 to a group of three shareholders
of LIPA (the "Shareholder Representative") within 120 days of the end of each
such year. United will make any payment due pursuant to the     

                                      10
<PAGE>
 
    
Contingent Payment Rights not later than 30 days following delivery of each 
Earn-Out calculation. See "THE MERGER--Contingent Payment Right 
Procedures."     

     RECOMMENDATION OF THE BOARD OF DIRECTORS OF LIPA

     The Board of Directors of LIPA believes that the Merger is in the best
interests of LIPA and its shareholders and has unanimously approved the Merger
Agreement. THE BOARD OF DIRECTORS OF LIPA UNANIMOUSLY RECOMMENDS APPROVAL AND
ADOPTION OF THE MERGER AGREEMENT TO LIPA'S SHAREHOLDERS. This recommendation is
based on a number of factors discussed in this Proxy Statement/Prospectus. See
"THE MERGER-LIPA's Reasons for the Merger; Recommendation of LIPA's Board of
Directors."

     OPINION OF LIPA'S FINANCIAL ADVISOR
    
     The Robinson-Humphrey Company, Inc. ("Robinson-Humphrey") has delivered its
written opinion to the Board of Directors of LIPA to the effect that, as of
April 22, 1996, the consideration to be received by the holders of LIPA Common
Stock pursuant to the Merger is fair to such shareholders from a financial point
of view. A copy of the opinion of Robinson-Humphrey, dated April 22, 1996, which
sets forth the assumptions made, matters considered and limits on the review
undertaken, is attached as Exhibit B to this Proxy Statement/Prospectus and is
incorporated by reference. Shareholders of LIPA are urged to read carefully the
opinion in its entirety. See "THE MERGER--Opinion of LIPA's Financial 
Advisor."     

     MANAGEMENT OF LIPA AFTER THE MERGER

     United Sub, as the Surviving Corporation, will remain a direct, wholly
owned subsidiary of United upon consummation of the Merger. The directors of
United Sub immediately prior to the Effective Time will be the initial directors
of the Surviving Corporation, and the officers of United Sub immediately prior
to the Effective Time will be the initial officers of the Surviving Corporation.
United currently expects that after the Effective Time most of the executive
officers of the Community Health Entities immediately prior to the Effective
Time will retain those positions. See "THE MERGER--Management of Surviving
Corporation After the Merger."

     INTERESTS OF CERTAIN PERSONS IN THE MERGER
    
     UHC Management Company, Inc., a wholly owned subsidiary of United, has
entered into consulting agreements with each of V. Lynn McCord, President of
LIPA, Kenneth C. Cranor, Chairman of the Board of Directors of LIPA, Williams D.
Wall, IV, Vice President of LIPA, and Thomas H. Benton, counsel for LIPA, (the
"Managers"). These agreements (the "Manager Agreements"), each of which has a
three-year term, provide that each Manager will provide certain consulting
services to United. The Manager Agreements prohibit the Managers from disclosing
any confidential information regarding United that may become known to the
Managers, and also contain non-solicitation and non-competition provisions. The
Manager Agreements provide that such obligations shall be waived to the extent
they may conflict with the performance of the duties of a Manager as a
Shareholder Representative. Aggregate annual compensation under the Manager
Agreements is $300,000. UHC has also entered into consulting agreements with
nine persons who have served on the boards of directors of LIPA and CHN and 20
shareholders of LIPA who serve on various committees of CHN with terms similar
to the Manager Agreements, except that the length of each of these agreements is
two years. The aggregate annual compensation due under the agreements to the
nine directors is $190,000, and to the 20 shareholders is $250,000. See "THE
MERGER--Interests of Certain Persons in the Merger."

     ACCOUNTING TREATMENT

     United intends to treat the Merger as a purchase for accounting and
financial reporting purposes.

     CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     The obligation of each of United and LIPA to consummate the Merger is
conditioned on, among other things, the receipt of an opinion of Dorsey &
Whitney LLP, counsel to United, based upon certain representations and
assumptions set forth therein, substantially to the effect that for federal
income tax purposes the Merger will qualify as a "reorganization" under Section
368(a) of the Internal Revenue Code of 1986, as amended (the "Code"). On the
basis of the foregoing opinion, it is expected that the following material
federal income tax consequences will result from the Merger: (1) no gain or loss
will be recognized by United, LIPA, or United Sub as a result of the Merger; (2)
no gain or loss will be recognized by any LIPA shareholder upon the exchange of
LIPA Common Stock for United Common Stock pursuant to the Merger (except to the
extent that (a) a Contingent Payment Right is taxable immediately upon its
receipt by a shareholder of LIPA Common Stock and (b) any cash is ultimately
received by a shareholder of LIPA Common Stock in connection with the receipt of
a fractional share interest in United Common Stock or on account of a Contingent
Payment Right); and (3) the basis of the United Common Stock received by a LIPA
shareholder who exchanges LIPA Common Stock for United Common Stock will be the
same as the basis of the LIPA Common Stock surrendered in exchange therefor
(subject to any current or future adjustments required as the result of (a) the
receipt of a Contingent Payment Right and (b) the receipt of cash in lieu of a
fractional share of United Common Stock or on account of a Contingent Payment
Right). If the required tax opinion is not received, the Merger will not be
consummated unless the condition requiring its receipt is waived and the
approvals of the United and LIPA shareholders are resolicited by means of an
updated Proxy Statement/Prospectus. EACH LIPA SHAREHOLDER IS URGED TO CONSULT
WITH HIS OR HER OWN TAX ADVISOR CONCERNING THE FEDERAL INCOME TAX CONSEQUENCES
OF THE MERGER, AS WELL AS ANY APPLICABLE STATE, LOCAL, FOREIGN OR OTHER TAX
CONSEQUENCES, BASED UPON SUCH SHAREHOLDER'S OWN PARTICULAR FACTS AND
CIRCUMSTANCES. See "THE MERGER--Certain Federal Income Tax Consequences."

     DISSENTERS' RIGHTS OF APPRAISAL

     Holders of LIPA Common Stock have the right to dissent from approval and
adoption of the Merger Agreement and, if the Merger is consummated upon a vote
of less than 80% of the total outstanding LIPA Common Stock, to receive payment
of the fair cash value of their shares (determined in accordance with Louisiana
law) upon compliance with the provisions of Section 131 of the LBCL, a copy of
which is attached to this Proxy Statement/Prospectus as Exhibit C and is
incorporated herein by reference. Shareholders of LIPA Common Stock are urged to
read Section 131 carefully. See "THE MERGER--Dissenters' Rights of Appraisal."

     REGULATORY APPROVALS

     Consummation of the Merger is conditioned upon, among other things, the
expiration or termination of all applicable waiting periods pursuant to the 
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"). The HSR Act requires that parties to certain acquisitions file
notifications with the federal antitrust authorities and observe a waiting
period prior to consummation. United and LIPA each initially filed Notification
and Report Forms with respect to the Merger under the HSR Act on January 25,
1996 and the applicable waiting period expired on February 25, 1996.
Consummation of the Merger is also conditioned upon the giving of all required
notices and obtaining receipt of all other regulatory approvals necessary for
consummation of the Merger, including the giving of notice or receipt of
approval under the federal Health Maintenance Organization Act of 1973 and the
applicable provisions of the Louisiana laws regulating HMOs and Insurance
Holding Company Systems. See "THE MERGER--Regulatory Approvals."

                                       12
<PAGE>
 
     RESALES OF UNITED COMMON STOCK

     The shares of United Common Stock to be issued to shareholders of LIPA in
connection with the Merger have been registered under the Securities Act of
1933, as amended (the "Securities Act"). All shares of United Common Stock
received by holders of LIPA Common Stock upon consummation of the Merger will be
freely transferable by those shareholders of LIPA not deemed to be "affiliates"
(as such term is defined under the Securities Act) of LIPA or United. See "THE
MERGER--Resales of United Common Stock Issued in the Merger."

     COMPARISON OF SHAREHOLDER RIGHTS

     Upon consummation of the Merger, LIPA shareholders will become United
shareholders. As a result, their rights as shareholders, which are now governed
by Louisiana corporate law and LIPA's Articles of Incorporation and Bylaws, will
be governed by Minnesota corporate law and United's Articles of Incorporation
and Bylaws. See "COMPARISON OF SHAREHOLDER RIGHTS" for a summary of certain
material differences between the rights of holders of United Common Stock and
the rights of holders of LIPA Common Stock.

THE MERGER AGREEMENT

     LIMITATIONS ON NEGOTIATIONS BY LIPA

     The Merger Agreement provides that LIPA may not initiate, solicit or
encourage any inquiries or the making of any proposal that constitutes, or may
reasonably be expected to lead to, (1) any sale of stock or other equity
interests, merger, consolidation, share exchange, business combination, or other
similar transaction; (2) any sale, lease, exchange, mortgage, pledge, transfer
or other disposition of any of LIPA's interest in the Community Health Entities
or 20% or more of the assets of LIPA in a single transaction or a series of
related transactions; or (3) any agreement to do, or public announcement by LIPA
of a proposal, plan or intention to do, any of the actions described in (1) or
(2) (each of (1), (2) and (3), referred to as a "Competing Transaction"), or
enter into discussions or negotiate with any person in furtherance of, or to
obtain a Competing Transaction, or agree to endorse a Competing Transaction, and
that LIPA will use its reasonable efforts to cause the directors, officers,
employees, agents and representatives of LIPA (as such persons are defined in
the Merger Agreement, see "THE MERGER AGREEMENT--Limitations on Negotiations by
LIPA") not to take such action, except in each such case as may be required in
order to comply with the Board of Directors' fiduciary duties, as evidenced by
the written opinion of counsel experienced in such matters. LIPA has agreed to
keep United informed regarding any inquiries or proposals with respect to a
Competing Transaction. See "THE MERGER AGREEMENT--Limitations on Negotiations by
LIPA."

     CONDITIONS TO THE MERGER
    
     The obligations of United and LIPA to consummate the Merger are subject to
the satisfaction of certain conditions (any or all of which may be waived to the
extent permitted by applicable law), including effectiveness of the Registration
Statement, requisite shareholder approval of the Merger Agreement, the absence
of any action, proceeding or injunction prohibiting consummation of the Merger,
the receipt of necessary regulatory and other approvals and consents, the
receipt of an opinion from legal counsel to the effect that the Merger will
qualify as a tax-free reorganization for federal income tax purposes, the
accuracy, as of the Effective Time, of representations and warranties in the
Merger Agreement, performance or compliance with the agreements and covenants in
the Merger Agreement, the receipt of "cold comfort" letters from each of United
and LIPA's respective independent public accountants and the receipt by LIPA of
a fairness opinion from Robinson-Humphrey. See "THE MERGER AGREEMENT--
Conditions."      

                                       13
<PAGE>
 
     TERMINATION OF THE MERGER AGREEMENT

     The Merger Agreement may be terminated at any time prior to the Effective
Time (1) by mutual written consent of United and LIPA; (2) by either United or
LIPA, if (a) any decree, permanent injunction, judgment, order or other action
by any court of competent jurisdiction or any governmental or regulatory
authority preventing or prohibiting consummation of the Merger shall have become
final and nonappealable, (b) if the Merger shall not have been consummated
before June 30, 1996, or a later date under certain circumstances set forth in
the Merger Agreement, (c) if the Merger Agreement shall fail to receive the
requisite vote for approval and adoption by the shareholders of LIPA at the
Special Meeting or any adjournment thereof or (d) the Average Stock Price is
more than $76.09 or less than $45.66; (3) by United, if LIPA has breached any of
its covenants or agreements contained in the Merger Agreement, or if any of the
representations and warranties of LIPA shall have become untrue, in any such
case such that the conditions to United's obligation to effect the Merger on
account of the continuing truth, accuracy and compliance with LIPA's
representations, warranties, agreements or covenants will not be satisfied (and
such breach or condition has not been cured by the earlier of 30 days following
receipt by LIPA of written notice of such breach or June 30, 1996 (or a later
date under certain circumstances set forth in the Merger Agreement)); (4) by
LIPA, if United has breached any of its covenants or agreements contained in the
Merger Agreement, or if any of the representations and warranties of United
shall have become untrue, in any case such that the conditions to LIPA's
obligation to effect the Merger on account of the continuing truth, accuracy and
compliance with United's representations, warranties, agreements or covenants
will not be satisfied (and such breach or condition has not been cured by the
earlier of 30 days following receipt by United of written notice of such breach
or June 30, 1996 (or a later date under certain circumstances set forth in the
Merger Agreement)); or (5) by LIPA, if United has entered into a written
agreement under which United will be acquired by or merge with another entity or
publicly announced its intention to enter into such a transaction, and after
such transaction, persons who were directors of United prior to such transaction
would not constitute a majority of the board of directors of the acquiring or
surviving corporation in such transaction.

     In the event of termination of the Merger Agreement by either United or
LIPA, the Merger Agreement will become void and there will be no liability or
obligation on the part of United, United Sub or LIPA, subject to certain
exceptions. See "THE MERGER AGREEMENT--Termination."

     FEES AND EXPENSES

     LIPA and United have agreed to bear their own expenses incurred in
connection with the Merger.

MARKET PRICE DATA
    
     The United Common Stock is listed on the NYSE under the symbol "UNH." There
is no public trading market for the LIPA Common Stock. The following table sets
forth the closing price per share of the United Common Stock and the "equivalent
per share price" (as defined below) of LIPA Common Stock as of (1) January 15,
1996, the last trading day before United and LIPA announced execution of the
Merger Agreement, and (2) April 26, 1996. The "equivalent per share price" of
LIPA Common Stock as of each date equals (1) the number of shares of United
Common Stock to be issued in the Merger based on each closing price, multiplied
by (2) the same such closing price, and divided by (3) the number of shares of
LIPA Common Stock outstanding on the Record Date.

United Common Stock at any time thereafter.

COMPARATIVE UNAUDITED PER COMMON SHARE DATA
    
     The following table presents selected comparative unaudited per share data
with respect to United Common Stock on a historical and a pro forma combined
basis, and with respect to LIPA Common Stock on a historical and pro forma
equivalent basis, giving effect to the Merger as a purchase for accounting and
financial reporting purposes. Such pro forma data assume that the Merger had
been effective on December 31, 1995 for the book value per share data and at the
beginning of the year ended December 31, 1995 for the dividends declared and net
earnings per share data. The table also presents book value per share data as of
December 31, 1995 and net earnings per share data for the year ended December
31, 1995, adjusted to give effect to United's October 2, 1995 acquisition of
MetraHealth and its April 12, 1996 merger with HealthWise as if the acquisition
and merger had occurred on December 31, 1995 with respect to the book value per
share data and January 1, 1995 with respect to the net earnings per share data.
The historical per share data set forth in the following table are derived from
and should be read in conjunction with the historical consolidated financial
statements of United, LIPA and HealthWise, including the notes thereto. The
audited historical consolidated statements of United are incorporated by
reference into this Proxy Statement/Prospectus. The audited historical
consolidated financial statements of LIPA are included in the Proxy
Statement/Prospectus. See "CONSOLIDATED FINANCIAL STATEMENTS OF LOUISIANA
INDEPENDENT PHYSICIANS ASSOCIATION, INC." and "INCORPORATION OF CERTAIN
DOCUMENTS BY REFERENCE." The per share data set forth below are presented for
informational purposes only and are not necessarily indicative of the results of
the future operations of the combined entity or the actual results that would
have been achieved had the acquisition of MetraHealth, and the mergers of LIPA
and HealthWise, been consummated on the dates indicated above.

     divided by the total pro forma common shares of the combined companies
     outstanding as of the date indicated, assuming conversion of the LIPA
     Common Stock at the Assumed Exchange Ratio. The pro forma equivalent book
     value per share of LIPA Common Stock represents the pro forma combined book
     value per share multiplied by the Assumed Exchange Ratio. The actual
     exchange ratio for the Pro Forma Combined and Pro Forma Equivalent
     information may differ depending on the price of United Common Stock on the
     date of exchange.    

(2)  The pro forma combined dividends per share for United Common Stock assumes
     no changes in cash dividends per share. The pro forma equivalent dividends
     per share for LIPA Common Stock represent the cash dividends declared on a
     share of United Common Stock multiplied by the Assumed Exchange Ratio. The
     actual exchange ratio for the Pro Forma Combined and Pro Forma Equivalent
     information may differ depending on the price of United Common Stock on the
     date of exchange.

(3)  The pro forma combined net earnings per share from continuing operations
     (based on fully diluted weighted average shares outstanding) of United
     Common Stock is based on the pro forma net earnings for the combined
     companies, divided by the pro forma weighted average common shares of the
     combined companies. The pro forma equivalent net earnings per share from
     continuing operations of LIPA Common Stock represents pro forma combined
     net earnings per share from continuing operations multiplied by the Assumed
     Exchange Ratio. The actual exchange ratio for the Pro Forma Combined and
     Pro Forma Equivalent information may differ depending on the price of
     United Common Stock on the date of exchange.

(4)  The as adjusted book value and net earnings per share data give effect to
     United's October 2, 1995 acquisition of MetraHealth and United's April 12,
     1996 merger with HealthWise as if the acquisition and merger had occurred
     on December 31, 1995 with respect to the book value per share data and on
     January 1, 1995 with respect to the net earnings per share data. The actual
     exchange ratio for the Pro Forma Combined and Pro Forma Equivalent
     information may differ depending on the price of United Common Stock on the
     date of exchange.

SUMMARY CONSOLIDATED FINANCIAL DATA OF UNITED
    
     The following table summarizes certain selected historical consolidated
financial data of United which should be read in conjunction with the
consolidated financial statements of United, and the notes thereto, incorporated
by reference into this Proxy Statement/Prospectus. The financial data for the
five years ended December 31, 1995 have been derived from the audited
consolidated financial statements of United. The following statement of
operations data does not include the estimated pro forma effects of United's
October 2, 1995 acquisition of MetraHealth and the statement of operations data
and balance sheet data do not include the estimated pro forma effects of the
April 12, 1996 merger with HealthWise. MetraHealth's financial results are
included in the summary financial data from the date of acquisition. United's
unaudited pro forma condensed combining financial statements giving effect to
the MetraHealth acquisition are included in this Proxy Statement/Prospectus. See
"UNAUDITED PRO FORMA CONDENSED COMBINING FINANCIAL INFORMATION." Each
acquisition described in the footnotes to the table below has been recorded
using the purchase method of accounting and accordingly, the operating results
of each acquired company have been included in United's historical financial
information from the respective dates of acquisition. The summarized historical
financial data should be read in conjunction with the consolidated financial

(1)  Excluding fourth quarter restructuring charges of $153.8 million ($96.9
     million after tax, or $0.55 per common share) associated with the
     MetraHealth acquisition, 1995 earnings from operations and net earnings
     would have been $614.6 million and $382.9 million, or $2.12 net earnings
     per common share.

(2)  On October 2, 1995, United acquired MetraHealth. The total purchase price
     of the acquisition was $1.09 billion in cash and $500 million of 5.75%
     convertible preferred stock, for total consideration at closing of $1.59
     billion. In addition, certain former owners of

     MetraHealth will be eligible to receive up to an additional $700 million if
     MetraHealth achieves certain defined operating results for each of the
     years ended December 31, 1995, 1996 and 1997. Had this transaction occurred
     on January 1, 1994, and excluding the effects of any potential future
     consideration, combined unaudited pro forma results for the years ended
     December 31, 1995 and 1994 would have been revenues - 8.71 billion and
     $7.98 billion; net earnings before extraordinary gain - $351.0 million and
     $337.0 million; net earnings -$351.0 million and $308.0 million; net
     earnings per common share before extraordinary gain - $1.98 and $1.76 and
     net earnings per common share - $1.98 and $9.62.

(3)  On January 3, 1995, United acquired GenCare Health Systems, (GenCare), a
     health plan based in St. Louis, Missouri, which served 230,000 members at
     the time of acquisition, for a total purchase price of $515.4 million in
     cash. Had the transaction occurred on January 1, 1994, combined unaudited
     pro forma results for the year ended December 31, 1994 would have been:
     revenues - $3.97 billion; net earnings before extraordinary gain - $284.9
     million; net earnings - $1.66 billion; net earnings per common share before
     extraordinary gain - $1.63 and net earnings per common share - $9.49.

(4)  On May 27, 1994, United sold Diversified Pharmaceutical Services, Inc.
     (Diversified), then a wholly-owned subsidiary, to SmithKline Beecham
     Corporation for $2.3 billion in cash. In connection with this transaction,
     United recognized an extraordinary gain after transaction costs and income
     tax effects of $1.38 billion, or $7.86 per share. The results of
     Diversified subsequent to the sale are not included in the financial
     information presented above.

(5)  On January 29, 1993, United acquired Western Ohio Health Care Corporation,
     then a 183,000-member HMO located in Dayton, Ohio, for a purchase price of
     $100.1 million

(6)  On January 2, 1992, United acquired Physicians Health Plan Corporation, the
     sole shareholder of Physicians Health Plan of Ohio, Inc., then a 154,000-
     member HMO located in Columbus, Ohio, for a purchase price of $89 million.
     In addition, United completed a public offering in March 1992 of ten
     million shares of United Common Stock, with net proceeds of $195.9 million.

(7)  United completed a public offering in March 1991 of 13.8 million shares of
     United Common Stock, with net proceeds of $99.1 million. On August 30,
     1991, United acquired approximately 79% of Ocean State Coordinated Health
     Services Corporation ("Ocean State"), the sole shareholder of Ocean State
     Physicians Health Plan, Inc. (subsequently renamed United Health Plans of
     New England, Inc.), then a 136,000-member HMO located in Warwick, Rhode
     Island, for a purchase price of $26.4 million. United previously owned 21%
     of Ocean State. As a result of the transaction, Ocean State became a 
     wholly-owned subsidiary of United.

                                 RISK FACTORS
    
     The following discussion contains certain cautionary statements regarding
United's business and results of operations which should be considered by LIPA
shareholders. These statements discuss matters which may in part be discussed
elsewhere in this Proxy Statement/Prospectus and which may have been discussed
in other documents prepared by United pursuant to federal or state securities
laws. This discussion is intended to take advantage of the "safe harbor"
provisions of the Private Securities Litigation Reform Act of 1995. The
following factors should be considered in conjunction with any discussion of
operations or results by United or its representatives, including any forward-
looking discussion, as well as comments contained in press releases,
presentations to securities analysts or investors, or other communications by
United.

     In making these statements, United is not undertaking to address or update
each factor in future filings or communications regarding United's business or
results, and is not undertaking to address how any of these factors may have
caused changes to discussions or information contained in previous filings or
communications. In addition, any of the matters discussed below may have
affected United's past results and may affect future results, so that the
Company's actual results for first quarter 1996 and beyond may differ materially
from those expressed in prior communications.

HEALTH CARE COSTS

     A large portion of the revenue received by United is expended to pay the
costs of health care services or supplies delivered to persons covered by its
health plan and insurance products. The total health care costs incurred by
United are affected by the number of individual services rendered and the cost
of each service. Much of the Company's premium revenue is set in advance of the
actual delivery of services and the related incurring of the cost, usually on a
prospective annual basis. While United attempts to base the premiums it charges
at least in part on its estimate of expected health care costs over the fixed
premium period, competition, regulations and other circumstances may limit
United's ability to fully base premiums on estimated costs. In addition, many
factors may and often do cause actual health care costs to exceed that estimated
and reflected in premiums. These factors may include increased utilization of
services, increased cost of individual services, catastrophes, epidemics,
seasonality, general inflation, new mandated benefits or other regulatory
changes and insured population characteristics. Historically, increases in
health care prices and utilization have caused health care costs to rise faster
than general inflation. In recent time periods these increases have moderated,
but there can be no assurance that health care prices or utilization will not
again increase at a more rapid pace.

MARKETING

     United markets its products and services through both employed sales people
and independent sales agents. Although United has a number of such sales
employees and agents, if certain key sales employees or agents or a large subset
of such individuals were to leave United, its ability to retain existing
customers and members could be impaired. In addition, certain of United's
customers or potential customers consider rating, accreditation or certification
of United by various private or governmental bodies or rating agencies necessary
or important. Certain of the Company's health plans or other business units may
not have obtained or may not desire or be able to obtain or maintain such
accreditation or certification which could adversely affect United's ability to
obtain or retain business with such customers. See "CERTAIN INFORMATION
CONCERNING UNITED--Marketing."

     The managed care industry has recently received significant amounts of
negative publicity. Such general publicity, or any negative publicity regarding
United in particular, could adversely affect United's ability to sell its
products or services or could create regulatory problems for United.     

                                       21
<PAGE>

     
COMPETITION

     In any of its geographic or product markets United competes with a number
of other entities, some of which may have certain characteristics or
capabilities which give them an advantage in competing with United. United
believes there are few barriers to entry in these markets, so that the addition
of new competitors can occur relatively easily. Certain of United's customers
may decide to perform for themselves functions or services formerly provided by
United, which would result in a decrease in United's revenues. Certain of
United's providers may decide to market products and services to United
customers in competition with United. In addition, significant merger and
acquisition activity has occurred in the industry in which United operates as
well as in industries which act as suppliers to United, such as the hospital,
physician, pharmaceutical and medical device industries. This activity may
create stronger competitors and/or result in higher health care costs. To the
extent that there is strong competition or that competition intensifies in any
market, United's ability to retain or increase customers, its revenue growth,
its pricing flexibility, its control over medical cost trends and its marketing
expenses may all be adversely affected. See "CERTAIN INFORMATION CONCERNING
UNITED--Competition."

PROVIDER RELATIONS

     One of the significant techniques United uses to manage health care costs
and utilization and monitor the quality of care being delivered is contracting
with physicians, hospitals and other providers. Because of the geographic
diversity of its health plans and the large number of providers with which most
of those health plans contract, United currently believes it has a limited
exposure to provider relations issues. In any particular market, however,
providers could refuse to contract with United, demand higher payments or take
other actions which could result in higher health care costs, less desirable
products for customers and members or difficulty meeting regulatory or
accreditation requirements.

     In some geographic markets, certain providers, particularly hospitals,
physician/hospital organizations or multi-specialty physician groups, may have
significant market positions or even monopolies. Many of these providers may
compete directly with United. If such providers refuse to contract with United
or utilize their market position to negotiate favorable contracts with United or
to place United at a competitive disadvantage, United's ability to market
products or to be profitable in those geographic areas could be adversely
affected.

ADMINISTRATION AND MANAGEMENT

     The level of administrative expense is a partial determinant of United's
profitability. While United attempts to effectively manage such expenses,
increases in staff-related and other administrative expenses may occur from 
time-to-time due to business or product start-ups or expansions, growth or
changes in business, acquisitions, regulatory requirements or other reasons.
Such expense increases are not clearly predictable and increases in
administrative expenses may adversely affect results.

     United's business is significantly dependent on effective information
systems. United has many different information systems for its various
businesses. United is in the process of attempting to reduce the number of
systems and also upgrade and expand its information systems capabilities.
Failure to maintain an effective and efficient information system could result
in loss of existing customers and difficulty in attracting new customers,
customer and provider disputes, regulatory problems, increases in administrative
expenses or other adverse consequences. In addition, United may, from time-to-
time, obtain significant portions of its systems-related or other services or
facilities from independent third parties which may make United's operations
vulnerable to such third party's failure to perform adequately.

     United currently believes it has a relatively experienced, capable
management staff. Loss of certain managers or a number of such managers could
adversely affect United's ability to administer     

                                      22
<PAGE>

     
and manage its business. The Company has made several large acquisitions in
recent years, and has an active ongoing acquisition program. Failure to
effectively integrate acquired operations could result in increased
administrative costs, less effective management of healthcare costs, customer
and provider dissatisfaction or difficulty in obtaining new customers or
retaining existing ones.

GOVERNMENT PROGRAMS AND REGULATION

     United's business is heavily regulated. The laws and rules governing
United's business and interpretations of those laws and rules are subject to
frequent change. Existing or future laws and rules could force United to change
how it does business and may restrict United's revenue and/or enrollment growth
and/or increase its health care and administrative costs. Regulatory approvals
must be obtained and maintained to market many of United's products and
services. Delays in obtaining or failure to obtain or maintain such approvals
could adversely affect United's revenue or the number of covered lives, or could
increase costs.

     A significant portion of United's revenues relate to federal, state and
local government health care coverage programs. These types of programs, such as
the federal Medicare program and the federal and state Medicaid program, are
generally subject to frequent change, including changes which may reduce the
number of persons enrolled or eligible, reduce the revenue received by United or
increase United's administrative or health care costs under such programs. Such
changes may even affect United's willingness to participate in such programs.

     United is also subject to various governmental audits and investigations.
Such activities could result in the loss of licensure or the right to
participate in certain programs, or the imposition of fines, penalties and other
sanctions. In addition, disclosure of any adverse investigation or audit results
or sanctions could negatively affect United's reputation in various markets and
make it more difficult for United to sell its products and services.

     See "CERTAIN INFORMATION CONCERNING UNITED--Government Regulation."

LITIGATION AND INSURANCE

     United is subject to a variety of legal actions to which any corporation
may be subject, including employment and employment discrimination-related
suits, employee benefit claims, breach of contract actions, tort claims,
shareholder suits, including for securities fraud, and intellectual property
related litigation. In addition, because of the nature of its business, United
incurs and likely will continue to incur potential liability for claims related
to its business, such as failure to pay for or provide health care, poor
outcomes for care delivered or arranged, provider disputes, including disputes
over withheld compensation, claims related to self-funded business and improper
copayment calculations. In some cases, substantial non-economic or punitive
damages may be sought. While United currently has insurance coverage for some of
these potential liabilities, others may not be covered by insurance, the
insurers may dispute coverage or the amount of insurance may not be enough to
cover the damages awarded. In addition, certain types of damages, such as
punitive damages, may not be covered by insurance and insurance coverage for all
or certain forms of liability may become unavailable or prohibitively expensive
in the future.

STOCK MARKET

     Recently, the market prices of the securities of certain of the publicly-
held companies in the industry in which United operates have shown volatility
and sensitivity in response to many factors, including public communications
regarding managed care, legislative or regulatory actions, health care cost
trends, pricing trends, competition, earnings or membership reports of
particular industry participants, and acquisition activity. There can be no
assurances regarding the level or stability of United's share price at any time
or of the impact of these or any other factors on the share price.

                              THE SPECIAL MEETING

GENERAL
    
     This Proxy Statement/Prospectus is being furnished to holders of LIPA
Common Stock in connection with the solicitation of proxies by the Board of
Directors of LIPA for use at a Special Meeting to be held on May 30, 1996, at
Glynnwood, 6230 Bluebonnet Boulevard, Baton Rouge, Louisiana 70809, commencing
at 6:30 p.m. local time, and at any adjournment or postponement thereof.     
    
     This Proxy Statement/Prospectus and accompanying form of proxy are first
being mailed to shareholders of LIPA on or about May 1, 1996.     

MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING

     At the Special Meeting, holders of LIPA Common Stock will (1) consider and
vote upon a proposal to approve and adopt the Merger Agreement, the Merger and
any transactions related thereto, to the extent that such transactions are
deemed transactions under Section 84 of the LBCL, see "THE MERGER--Interests of
Certain Persons in the Merger," and (2) transact such other business as may
properly come before the Special Meeting or any postponement or adjournment
thereof.

BOARD OF DIRECTORS' RECOMMENDATION

     THE BOARD OF DIRECTORS OF LIPA BELIEVES THAT THE MERGER AGREEMENT IS IN THE
BEST INTERESTS OF LIPA AND ITS SHAREHOLDERS AND UNANIMOUSLY RECOMMENDS APPROVAL
AND ADOPTION OF THE MERGER AGREEMENT TO ITS SHAREHOLDERS.

RECORD DATE; VOTING AT THE SPECIAL MEETING; REQUIRED VOTE
    
     LIPA has fixed April 30, 1996, as the Record Date for the determination of
the holders of LIPA Common Stock entitled to notice of and to vote at the
Special Meeting. Accordingly, only holders of record of LIPA Common Stock on the
Record Date will be entitled to notice of and to vote at the Special Meeting. As
of the Record Date, there were 418 shares of LIPA Common Stock outstanding and
entitled to vote, which shares were held in the aggregate by 411 holders of
record. Each holder of record of LIPA Common Stock on the Record Date is
entitled to cast one vote per share of LIPA Common Stock, exercisable in person
or by properly executed proxy, at the Special Meeting. The presence, in person
or by properly executed proxy, of the holders of a majority of the LIPA Common
Stock entitled to vote at the Special Meeting is necessary to constitute a
quorum at the Special Meeting.     

     The approval and adoption of the Merger Agreement by the shareholders of
LIPA will require the affirmative vote of the holders of two-thirds of LIPA
Common Stock present at the Special Meeting (assuming a quorum is present). If
an executed proxy card is returned and the shareholder has abstained from voting
on any matter, the shares represented by such proxy will be considered present
at the meeting for purposes of determining a quorum and for purposes of
calculating the vote but will not be considered to have been voted in favor of
such matter. Accordingly, abstentions will have the same effect as a vote
against the Merger Agreement.

     As of the Record Date, neither United nor any of its directors or executive
officers or their affiliates beneficially owned any shares of LIPA Common Stock.

                                      24
<PAGE>
 
PROXIES

     All shares of LIPA Common Stock represented at the Special Meeting by
properly executed proxies received prior to or at the Special Meeting, and not
revoked, will be voted at the Special Meeting in accordance with the
instructions indicated on such proxies. If no instructions are indicated, such
proxies will be voted for approval and adoption of the Merger Agreement. If any
other matters are properly presented at the Special Meeting for consideration,
including, among other things, consideration of a motion to postpone or adjourn
the Special Meeting to another time or place, the persons named in the enclosed
form of proxy and acting thereunder will have discretion to vote on such matters
in accordance with their best judgment.

     Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before it is voted. Proxies may be revoked by (1) filing
with the Secretary of LIPA, at or before the taking of the vote at the Special
Meeting, a written notice of revocation bearing a later date than the proxy, (2)
duly executing a later dated proxy relating to the same shares and delivering it
to the Secretary of LIPA before the taking of the vote at the Special Meeting,
or (3) attending the Special Meeting and voting in person (although attendance
at the Special Meeting will not in and of itself constitute a revocation of a
proxy). Any written notice of revocation or subsequent proxy should be sent so
as to be delivered to Louisiana Independent Physicians Association, Inc., 8550
United Plaza Boulevard, Suite 600, Baton Rouge, Louisiana 70809, Attention:
Corporate Secretary, or hand delivered to the Secretary of LIPA at or before the
taking of the vote at the Special Meeting.

     The meeting may be postponed or adjourned from time to time without notice
other than such notice as may be given at the meeting or any postponement or
adjournment thereof, including, without limitation, if a quorum is not obtained,
or if fewer shares are likely to be voted in favor of approval and adoption of
the Merger Agreement than the number required for approval. Any business for
which notice has been given may be transacted at any such postponed or adjourned
meeting. If the Special Meeting is postponed or adjourned for the purpose of
obtaining additional proxies or votes or for any other purpose, at any
subsequent reconvening of the Special Meeting, all proxies will be voted in the
same manner as such proxies would have been voted at the original convening of
the meeting (except for any proxies which have theretofore effectively been
revoked or withdrawn), notwithstanding that they may have been effectively voted
on the same or any other matter at a previous meeting.

     Pursuant to the Merger Agreement, all expenses related to the printing,
filing and mailing of the Registration Statement and this Proxy
Statement/Prospectus will be borne by the party that incurs such expenses. In
addition to use of the mails, proxies may be solicited personally or by
telephone or telegraph by directors, officers and employees of LIPA, who will
not be specially compensated for such activities.

SHAREHOLDERS SHOULD NOT SEND ANY STOCK CERTIFICATES WITH THEIR PROXY CARDS. THE
PROCEDURE FOR THE EXCHANGE OF YOUR SHARES AFTER THE MERGER IS CONSUMMATED IS SET
FORTH IN THIS PROXY STATEMENT/PROSPECTUS. SEE "THE MERGER--PROCEDURES FOR
EXCHANGE OF CERTIFICATES AND WAIVER OF CLAIMS."

                                  THE MERGER

     The following information describes the material aspects of the Merger.
This description does not purport to be complete and is qualified in its
entirety by reference to the Exhibits hereto, including the Merger Agreement,
which is attached to this Proxy Statement/Prospectus as Exhibit A and is
incorporated herein by reference. All shareholders are urged to read Exhibit A
in its entirety. See also "THE MERGER AGREEMENT."

EFFECTS OF THE MERGER

     Upon consummation of the Merger, (1) LIPA will merge with and into United
Sub, which will be the Surviving Corporation, (2) LIPA will cease to exist, and
(3) each share of LIPA Common Stock outstanding, other than Dissenting Stock,
will be converted into the right to receive a pro rata allotment of an aggregate
number of shares of United Common Stock equal to $50,000,000 divided by the
Average Stock Price; provided, however, that the number of shares issuable in
the Merger will be fixed at (1) 938,692 if the Average Stock Price is at least
$49.2707 but less than $53.2656, or (2) 730,093 if the Average Stock Price is
more than $68.4844 but not more than $73.0500. If the Average Stock Price is
more than $73.0500, the number of shares issuable in the Merger will be (1)
$53,750,000 divided by (2) the Average Stock Price. If the Average Stock Price
is less than $49.2707, the number of shares issuable in the Merger will be (1)
$46,250,000 divided by (2) the Average Stock Price.
    
     Assuming that the Average Stock Price equals the closing price per share of
United Common Stock on the NYSE on April 26, 1996, or $58.3750, and that the
number of shares of LIPA Common Stock outstanding at the Effective Time equals
the 418 shares of LIPA Common Stock outstanding as of the Record Date, each
outstanding share of LIPA Common Stock would be converted into the right to
receive approximately 2,049 shares of United Common Stock, having a market value
of approximately $119,600.     
    
     The following table sets forth other examples of the number of shares of
United Common Stock into which each outstanding share of LIPA Common Stock would
be converted at the time of the Merger, and the estimated market value thereof,
assuming that (1) the number of shares of LIPA Common Stock outstanding at the
Effective Time equals the 418 shares of LIPA Common Stock outstanding as of the
Record Date and (2) that, in each example, the Average Stock Price equals the
closing price per share of United Common Stock on the NYSE on the day of the
Merger.

     for the ten trading days ending with and including the second trading day
     preceding the closing of the Merger.

     of LIPA Common Stock would be converted.

     Common Stock into which each outstanding share of LIPA Common Stock would
     be converted.     
    
     IF, AT THE EFFECTIVE TIME, THE AVERAGE STOCK PRICE IS MATERIALLY OUTSIDE
THE RANGE OF $49.2707 (REPRESENTING AN EXCHANGE RATIO OF APPROXIMATELY 2,245
SHARES) TO $73.0500 (REPRESENTING AN EXCHANGE RATIO OF APPROXIMATELY 1,746
SHARES) UNITED AND LIPA WOULD RESOLICIT PROXIES FROM ALL SHAREHOLDERS OF LIPA
AND RECONVENE THE SPECIAL MEETING. SUCH ACTION, IF IT OCCURS, WOULD CAUSE THE
EFFECTIVE TIME OF THE MERGER TO BE DELAYED.     

     In addition to United Common Stock, at the effective time of the Merger
each share of LIPA Common Stock outstanding, other than Dissenting Stock, will
receive one Contingent Payment Right to receive two contingent cash payments,
net of any amount to which United is entitled pursuant to the indemnification
provisions of the Merger Agreement. The aggregate amount of such payments will
be determined by reference to the Adjusted Net Income of the Community Health
Entities and MetraHealth Louisiana. For the period January 1, 1996 to December
31, 1996, the Earn-Out will equal the amount, if any, by which Adjusted Net
Income exceeds $10.0 million, multiplied by 6.3. For the period January 1, 1997
to December 31, 1997, the Earn-Out will equal the amount, if any, by which
Adjusted Net Income exceeds $16.5 million, multiplied by 4.5. In no case,
however, can the aggregate of the two Earn-Outs exceed $35.0 million (or
approximately $84,000 per share of LIPA Common Stock). The amount payable to
each holder of a Contingent Payment Right will be equal to the Earn-Out for the
applicable year divided by the number of Contingent Payment Rights outstanding
at the time payment is due. See "--Contingent Payment Right Procedures."

     All shares of LIPA Common Stock converted into shares of United Common
Stock in the Merger will no longer be outstanding and will automatically be
canceled and retired and will cease to exist at the Effective Time. Each
certificate previously representing shares of LIPA Common Stock will thereafter
represent the right to receive a certificate representing shares of United
Common Stock. Certificates previously representing shares of LIPA Common Stock
may be exchanged for certificates representing whole shares of United Common
Stock issued in consideration therefor upon the surrender

                                      27
<PAGE>
 
of such certificates as provided below, without interest. No fractional shares
of United Common Stock will be issued, and, in lieu thereof, a cash payment will
be made as provided below. Each share of LIPA Common Stock held in the treasury
of LIPA or owned by any direct or indirect wholly owned subsidiary of LIPA
immediately prior to the Effective Time will be canceled and extinguished
without any conversion thereof, and no payment will be made with respect
thereto.

     For a description of the procedures for exchanging LIPA Common Stock for
United Common Stock and for payment of cash in lieu of the issuance of
fractional shares, see "--Procedures for Exchange of Certificates" and 
"--Fractional Shares."

EFFECTIVE TIME

     If the Merger Agreement is approved and adopted by the requisite vote of
the shareholders of LIPA and the other conditions to the Merger are satisfied
(or waived to the extent permitted), the Merger will be consummated and effected
at the time the certificate of merger is filed with the Secretary of State of
the State of Louisiana.

     The closing of the transactions contemplated by the Merger Agreement will
take place on the last business day of the month during which all of the
conditions to the Merger are satisfied (or waived to the extent permitted) or on
such other date, time and place as United and LIPA may agree. The Merger
Agreement may be terminated by either United or LIPA in certain circumstances
notwithstanding the prior approval and adoption of the Merger Agreement by the
shareholders of LIPA. See "THE MERGER AGREEMENT--Termination."

PROCEDURES FOR EXCHANGE OF CERTIFICATES AND WAIVER OF CLAIMS

     As of the Effective Time, United will deposit, or will cause to be
deposited, with a bank or trust company designated by United and acceptable to
LIPA (the "Exchange Agent"), for the benefit of the holders of shares of LIPA
Common Stock, for exchange in accordance with the terms of the Merger Agreement,
certificates representing the shares of United Common Stock (such certificates
for shares of United Common Stock, together with any dividends or distributions
with respect thereto and appropriate cash payments in lieu of fractional shares
of United Common Stock, being hereinafter referred to as the "Exchange Fund")
issuable pursuant to the Merger Agreement in exchange for outstanding shares of
LIPA Common Stock. The Exchange Agent will, pursuant to irrevocable
instructions, deliver the United Common Stock contemplated to be issued pursuant
to the Merger Agreement out of the Exchange Fund.

     Promptly after the Effective Time, United will instruct the Exchange Agent
to mail to each holder of record of a Certificates (1) a letter of transmittal
in customary form (which will specify that delivery will be effected, and risk
of loss and title to the Certificates will pass, only upon proper delivery of
the Certificates to the Exchange Agent), and (2) instructions for use in
effecting the surrender of the Certificates in exchange for certificates
representing shares of United Common Stock. Upon surrender of a Certificate for
cancellation to the Exchange Agent together with a duly executed letter of
transmittal, which will also include the Waiver (as described in the paragraph
immediately following), and any other documents as may be required pursuant to
such instructions, the holder of the Certificate will be entitled to receive in
exchange therefor a certificate representing that number of whole shares of
United Common Stock which the holder has received in respect of the shares of
LIPA Common Stock formerly represented by the Certificate, cash in lieu of
fractional shares of United Common Stock (after taking into account all shares
of LIPA Common Stock then held by the holder) and any dividends or other
distributions to which the holder is entitled pursuant to the Merger Agreement,
and the Certificate so surrendered will forthwith be canceled. In the event of a
transfer of ownership of shares of LIPA Common Stock which is not registered in
the transfer records of LIPA, a certificate representing the proper number of
shares of United Common Stock, together with cash in lieu of

                                      28
<PAGE>
 
fractional shares of United Common Stock and any dividends or other
distributions to which such holder is entitled, may be issued to a transferee if
the Certificate representing such shares of LIPA Common Stock is presented to
the Exchange Agent, accompanied by all documents required to evidence and effect
such transfer and by evidence that any applicable stock transfer taxes have been
paid. Until surrendered, each Certificate shall be deemed at any time after the
Effective Time to represent only the right to receive upon surrender the
certificate representing shares of United Common Stock, cash in lieu of any
fractional shares of United Common Stock and any dividends or other
distributions to which the holder is entitled as described below.

     The Waiver, the form of which is Exhibit 2.02(b) to the Merger Agreement,
is a release by a LIPA shareholder of United, LIPA, the Community Health
Entities, and United's subsidiaries, officers, directors, employees and agents
from all claims that a shareholder may have relating to the provision by the
shareholder of services to the Community Health Entities prior to January 1,
1995. The Waiver is intended to cover claims in connection with withholding
arrangements between providers and CHN that existed prior to January 1, 1995
under certain provider contracts. The Waiver functions as an alternative to a
representation, with related indemnification provisions, in the Merger Agreement
by LIPA that it had settled all outstanding claims concerning these withholding
arrangements. United required this more effective form of protection as a
condition to the acceptance of its final offer of merger terms. See 
"--Background of the Merger."

SHAREHOLDERS OF LIPA SHOULD NOT FORWARD THEIR STOCK CERTIFICATES TO THE EXCHANGE
AGENT WITHOUT A LETTER OF TRANSMITTAL AND SHOULD NOT RETURN THEIR STOCK
CERTIFICATES WITH THE ENCLOSED PROXY.

     No dividends or other distributions declared or made after the Effective
Time with respect to United Common Stock with a record date after the Effective
Time will be paid to the holder of any unsurrendered Certificate with respect to
the shares of United Common Stock represented thereby, and no cash payment in
lieu of fractional shares will be paid to any such holder, until the holder of
the Certificate has surrendered such Certificate. Subject to the effect of
escheat, tax or other applicable laws, following surrender of any such
Certificate, there will be paid to the holder of the certificates representing
whole shares of United Common Stock issued in exchange therefor, without
interest, (1) promptly, the amount of any cash payable with respect to a
fractional share of United Common Stock to which such holder is entitled and the
amount of dividends or other distributions with a record date after the
Effective Time theretofore paid with respect to such whole shares of United
Common Stock, and (2) at the appropriate payment date, the amount of dividends
or other distributions, with a record date after the Effective Time but prior to
surrender and a payment date occurring after surrender, payable with respect to
such whole shares of United Common Stock. All shares of United Common Stock
issued upon conversion of the shares of LIPA Common Stock (including any cash
paid for fractional shares and for dividends or other distributions described
above) will be deemed to have been issued in full satisfaction of all rights
pertaining to such shares of LIPA Common Stock, other than the right to receive
the Earn-Outs, if any. See "THE MERGER--Contingent Payment Rights."

     Any portion of the Exchange Fund remaining undistributed one year after the
Effective Time will be returned to United, upon demand, and any holders of
theretofore unsurrendered LIPA Common Stock will thereafter be able to look only
to United for any portion of the Exchange Fund to which they are entitled.
Neither United nor LIPA will be liable to any holder of shares of LIPA Common
Stock for any such shares of United Common Stock (or dividends or distributions
with respect thereto) or cash in lieu of fractional shares delivered to a public
official pursuant to any abandoned property, escheat or similar law.

                                      29
<PAGE>
 
FRACTIONAL SHARES

     No certificates or scrip representing fractional shares of United Common
Stock will be issued upon the surrender for exchange of Certificates, and such
fractional share interests will not entitle the owner thereof to vote or to any
other rights of a shareholder of United. Each holder of Certificates who
otherwise would be entitled to receive a fractional share of United Common Stock
will receive, in lieu of such fractional share interest, an amount in cash
(without interest) determined by multiplying (1) the closing sale price per
share of United Common Stock as reported on the NYSE on the business day
immediately preceding the date of closing of the Merger by (2) the fractional
share interest to which such holder would otherwise be entitled. United will
transfer to the Exchange Agent on a timely basis the cash necessary to make such
payments. As soon as practicable after the determination of the amount of cash,
if any, to be paid to holders of LIPA Common Stock with respect to any
fractional share interests, the Exchange Agent will promptly pay such amounts to
holders of LIPA Common Stock at such time as they have surrendered their
Certificates.

CONTINGENT PAYMENT RIGHTS
    
     Within 120 days following the end of each of the years ended December 31,
1996 and December 31, 1997 (the "Earn-Out Years"), United will deliver to Dr. V.
Lynn McCord, Dr. Williams D. Wall, IV, and Dr. Kenneth C. Cranor, or their
properly designated successors (collectively, the "Shareholder Representative"),
a calculation of the Earn-Out with respect to such year based in part on payment
lag data for such year available not less than 90 days following the end of
such year, together with (1) the certification of the chief financial officers
of United and the Surviving Corporation to the effect that (a) United and
Surviving Corporation have not disposed of all or substantially all of their
respective interests in the Community Health Entities or otherwise combined the
operations of such entities, unless United shall have made reasonably adequate
provisions to provide for the determination of the Earn-Out, and (b) that United
and the Surviving Corporation have maintained their respective books and records
in accordance with generally accepted accounting principles; and (2) the
certification of such officers and the independent certified public accountants
of United or the Surviving Corporation to the effect that the calculation is in
accordance with an audit by such accountants for the Community Health Entities.
The Shareholder Representative may contest the calculation of the Earn-Out in
accordance with certain procedures, including the arbitration of unresolved
issues. United shall make any payment due under the Contingent Payment Rights to
each holder thereof by cashier's or certified check not later than 30 days
following delivery of each Earn-Out calculation. Contingent Payment Rights are
personal to each initial holder of such rights and are not transferable for any
reason other than by operation of law or by will or the laws of descent and
distribution. Contingent Payment Rights will not be represented by any
certificate or similar instrument.     

BACKGROUND OF THE MERGER

     On May 31, 1994, United and Complete Health Services, Inc. ("Complete")
consummated a merger pursuant to which United became the owner of approximately
51% of LHMC, 49% of CHN and 51% of LHP, with LIPA holding the remaining interest
in these entities. See "CERTAIN INFORMATION CONCERNING LIPA--The Business of
LIPA." Shortly after the announcement of the merger of United and Complete, LIPA
objected to Complete regarding the exclusion of LIPA from the merger
negotiations. LIPA's understanding of Complete's response was that LIPA's
participation in the negotiations was not possible and that United would have to
wait two years before it could seek a merger with LIPA. Based on this
understanding, LIPA's Board of Directors (the "LIPA Board") abandoned its
request to negotiate and cooperated in the transition of the management
resulting from United's merger with Complete, in the belief that the new joint
ownership would substantially increase the value of LIPA's interest in the
Community Health Entities.

                                      30

     On February 7, 1995, United offered to buy LIPA's interest in the Community
Health Entities. On February 10, 1995, the LIPA Board initiated a discussion of
LIPA's strategic options and methods by which the LIPA Board could effectively
evaluate those options. Dr. McCord, Dr. Kenneth C. Cranor, Chairman of the Board
of Directors of CHN, and Thomas H. Benton, LIPA's senior legal counsel,
expressed the view to the Board that it was not then a good time to negotiate a
sale to United. The reasons for this view were that (1) the LIPA Board lacked
sufficient information about the value of LIPA, (2) the recent departure of the
CHN chief executive officer created an uncertain environment and (3) CHN would
soon experience increased profit margins due to the introduction of new
products. Dr. McCord informed United that the LIPA Board had decided to delay
further negotiations for these reasons. On February 27, 1995, LIPA communicated
to its shareholders United's offer to buy LIPA's interest in the Community
Health Entities and the decision to delay negotiations with United.

     Thereafter, Dr. McCord, Dr. Cranor, Dr. Williams D. Wall, IV, LIPA's Vice
President, and personnel from Thomas H. Benton & Associates (the "Benton Law
Firm") studied recent HMO acquisitions in general and United acquisitions in
particular. As part of the process, this group gave the Complete transaction
with United particular scrutiny. LIPA also informed several investment banks of
United's interest in acquiring LIPA's interest in the Community Health Entities.
As a result, several inquiries were received and a national investment banking
firm offered to review the operations of the Community Health Entities without
obligation. This offer was accepted, and on April 6, 1995, the investment bank
sent a three person team to Baton Rouge. This team interviewed senior management
and reviewed financial reports, then advised orally representatives of LIPA
regarding methods for valuing HMO acquisitions.

     In its review of the strategic options available to LIPA, the LIPA Board
considered, in addition to the financial condition and outlook of LIPA, the
following factors that might adversely impact the value of LIPA: (1) the then-
current general decline of HMO acquisition values in the national market; (2)
the resignation of CHN's chief executive officer and the existing vacancy in
that position; (3) that few potential buyers would be interested in acquiring
LIPA's holdings because LIPA did not own a controlling interest in the
management company; and (4) uncertainty concerning LIPA's projected income
figures for the next two years.

     On June 26, 1995, United announced its agreement to acquire MetraHealth. As
a result of this acquisition, which United consummated on October 2, 1995,
United acquired approximately 200,000 covered lives in Louisiana, 12,000 of whom
were in CHN's service areas in New Orleans and Baton Rouge.

     On July 18, 1995, Dr. McCord and Dr. Cranor met with representatives of
United. Following that meeting, in a letter dated July 20, United provided a
list of six alternatives to the previous United offer. United proposed that LIPA
either (1) sell 100% of its interest in the Community Health Entities to United,
(2) sell less than 100% of its interest in the Community Health Entities to
United, (3) retain its current interest in the Community Health Entities, but if
United were to acquire a competing HMO, the acquired entity would be merged into
CHN as additional paid in capital from United, thereby reducing the percentage
of LIPA's equity interest, (4) contribute equally to the cost of such an
acquisition of an competing HMO, (5) perform some combination of the actions
described in (2) and (3) above, or (6) maintain the status quo.

     The LIPA Board met on July 27, 1995 to consider United's offer and related
alternatives. Given the recent acquisition of MetraHealth by United, the hiring
of a new CEO and the recent substantial increases in CHN's monthly income, the
LIPA Board authorized Drs. McCord, Cranor, Wall and Mr. Thomas H. Benton
(collectively, the "Committee") to engage in negotiations for a possible
acquisition of LIPA by United on the basis of a tax-free exchange of shares.

                                      31
<PAGE>
 
     The Committee was authorized to consult with H. J. Lowe and Company, LIPA's
accountants, for any appropriate assistance, including the recommendation of
additional consultants. The Committee was instructed to consult with the LIPA
Board regarding each offer. The consensus of the LIPA Board was that the value
to United of the holdings of LIPA should reflect (1) current monthly income,
which had recently increased and was expected to remain at this higher level;
(2) the non-compete covenant with United, which had an economic value separate
and apart from the value of LIPA; (3) that control of 100% of the Community
Health Entities had value to United; and (4) that United faced potential
conflicts due to the MetraHealth acquisition.

     Accordingly, the LIPA Board sent to United on August 25, 1995 a written
offer to sell LIPA for $110 million based, in part, on the factors listed above.
In response to this letter, United at an August 28, 1995 meeting offered $40
million for LIPA and urged the Committee to seek investment banking advice in
evaluating the offer. United also suggested that an earn-out, which would
provide additional compensation to the shareholders of LIPA if the earnings of
the Community Health Entities reached specified levels, could address the
difference in opinion concerning the valuation of the Community Health Entities.
Shortly thereafter, the Committee, together with LIPA's accountants, performed a
valuation analysis based upon various assumed growth rates. This valuation
analysis was compared to an analysis that United prepared. United's and LIPA's
representatives had several discussions regarding basic assumptions underlying
the valuation analyses.

     In the course of these discussions, United informed LIPA that as a
condition of the Merger United would require consulting agreements containing
non-compete covenants with key personnel of LIPA. In order to avoid any conflict
of interest on the part of the Committee members, the Committee and United
deferred discussion of such agreements until the conclusion of price
negotiations.

     On September 5, 1995, another meeting was held in Baton Rouge, which
included United's chairman and chief executive officer, Dr. William W. McGuire,
M.D. On October 13, 1995, United made an offer of approximately $50 million in
stock plus a $35 million cash earn-out, subject to the receipt of a release from
each shareholder regarding withholding arrangements in pre-1995 provider
contracts, in lieu of a representation by LIPA and related indemnification
provisions addressing this concern. On October 27, 1995, United revised the 
earn-out terms, and indicated that this was its final offer. This final offer
contained the condition that consulting agreements be received from certain key
LIPA personnel, including the four Committee members, physicians that were board
members of LIPA and CHN and physicians serving on the existing committees of
CHN. United insisted on these agreements in order to effect a smooth transition
of control of the Community Health Entities and to maintain local participation
in management of CHN.

     The Committee recommended to the LIPA Board that LIPA should retain counsel
experienced in corporate mergers to advise LIPA regarding the merger
documentation and the request for the consulting agreements. Accordingly, LIPA
retained the New Orleans firm of Correro, Fishman & Casteix, L.L.P. as special
merger counsel ("Special Merger Counsel").

     The LIPA Board considered United's final offer at a December 7, 1995
meeting, which Special Merger Counsel attended. The Committee reported that it
approved the offer subject to the resolution of certain matters. At that
meeting, the LIPA Board chose The Robinson-Humphrey Company, Inc., an investment
banking firm headquartered in Atlanta, Georgia, to perform a fairness
evaluation. Following the meeting, United performed certain due diligence
regarding LIPA. United also presented a draft of the proposed merger agreement
to LIPA. Special Merger Counsel, together with the Benton Law Firm, negotiated
the terms of the Merger Agreement with United over the next few weeks.

     The LIPA Board met on January 9, 1996, at which time a draft of the
Robinson-Humphrey report was given to each Board member for study, and
representatives of Robinson-Humphrey discussed the report. The report concluded
that the proposed merger was fair to the shareholders of LIPA from a

                                      32
<PAGE>
 
financial point of view. See "THE MERGER--Opinion of LIPA's Financial Advisor."
Also at that meeting, Special Merger Counsel reviewed with the LIPA Board the
proposed merger agreement and suggested that the LIPA Board further study the
Robinson-Humphrey report and the Merger Agreement before voting whether to
approve the proposed merger agreement.

     The LIPA Board held a meeting to vote on the approval of the proposed
merger agreement on January 11, 1996. Special Merger Counsel attended that
meeting and representatives from Robinson-Humphrey were present by telephone.
The LIPA Board discussed whether to approve the proposed merger agreement or to
remain independent as a part owner of CHN. The benefits and risks inherent in
each choice were discussed. The LIPA Board also discussed whether it could
terminate the management contract between Complete (now a United subsidiary) and
LIPA and whether, absent such contract, any other purchaser might buy LIPA's 51%
ownership of CHN. This alternative was rejected because it would initiate an
adversarial relationship with United, which could reduce LIPA's value, and
because the LIPA Board considered it unlikely that a prospective buyer would
offer a higher price than that offered by United. The LIPA Board further
determined that retaining LIPA's separate interest in CHN was not in the best
interest of LIPA's shareholders because it could result in a hostile, perhaps
even unprofitable, relationship between United and LIPA. Furthermore, in light
of the increasing level of competition in the health care industry and the
recent changes to the Medicare and Medicaid programs, it was determined that
United's size and expertise would provide better growth opportunities for CHN
than if CHN's ownership remained divided. On the basis of the recommendations
and opinions it received, the LIPA Board unanimously authorized the execution of
the proposed merger agreement and its submission to a vote by LIPA's
shareholders. The Merger Agreement was duly executed effective January 16, 1996.
    
     On April 22, 1996 the LIPA Board met to hear and review (1) an updated
presentation by Robinson-Humphrey, (2) updated financial information about LIPA,
including results of operations for the first quarter of 1996, and (3) updated
financial information about United, including results of operations for year-end
1996 as disclosed on United's Annual Report on Form 10-K. Based on its review of
this information and this Proxy Statement/Prospectus, the LIPA Board voted
unanimously to recommend the Merger to LIPA's shareholders, to confirm its
earlier approval of the Merger and to approve the distribution of this Proxy
Statement/Prospectus to the LIPA shareholders.     

LIPA'S REASONS FOR THE MERGER; RECOMMENDATION OF LIPA'S BOARD OF DIRECTORS
    
     By the unanimous vote of the entire LIPA Board at a special meeting held on
January 11, 1996, the LIPA Board determined that the proposed Merger Agreement
was in the best interests of LIPA and its shareholders. The Merger Agreement was
adopted and approved by the entire LIPA Board. At a special meeting held April
22, 1996, the LIPA Board affirmed this approval and also unanimously resolved
to recommend that the shareholders of LIPA vote "FOR" approval and adoption of
the Merger Agreement. In reaching its conclusion to enter into the Merger
Agreement and to recommend that the shareholders of LIPA vote for the approval
and adoption of the Merger Agreement, the Board of Directors of LIPA considered
a number of factors, including, without limitation and without assigning
relative weights thereto, the factors described in the preceding two paragraphs.
See "--Background of the Merger." In making these determinations the Board was
cognizant that achieving a significant, or even any, Earn-Out payment was
speculative, as it depends on various factors that are not reliably predictable.
Moreover, for an Earn-Out to become payable the Community Health Entities would
have to perform at a substantially more profitable level than they have ever
previously performed. The Board was mindful, however, that several factors
could, separately or in combination with each other, create a synergy following
the Merger that could result in the Earn-Out being achieved. These factors are
the inclusion of MetraHealth Louisiana in the earnings of CHN for purposes of
the Earn-Out, and the freedom of operations that United would achieve from a
resolution of the possible conflicts of interest inherent in having two separate
operations in Louisiana (CHN and MetraHealth Louisiana). The Board believes that
the Earn-Out will serve to capture the benefit from this synergy, should it     

                                       33
<PAGE>

     
result in substantial improvement to CHN's earnings. Nonetheless, the Board
recommends that in making their decisions on how to vote with respect to the
Merger Agreement, shareholders should not assign any value to the Earn-Out.    

UNITED'S REASONS FOR THE MERGER

     As part of its acquisition of Complete Health Services, Inc. in 1994,
United acquired an interest in the Community Health Entities. In general, United
prefers to have 100% ownership of health plans. Therefore, United has had
periodic discussions with LIPA regarding the purchase of its interest in the
Community Health Entities, concluding with the Merger Agreement. In addition,
United acquired another health plan in Louisiana in connection with the
MetraHealth acquisition, along with other health care coverage business in
Louisiana. United believes that 100% ownership of the Community Health Entities
will facilitate combining and expanding all of United's Louisiana operations.
The presence of the non-competition clause with LIPA would have caused
significant conflicts and difficulties for United in operating separate health
plans in Louisiana. United also believes that following the Merger it will
continue to have a strong relationship with LIPA's managers and provider owners.

OPINION OF LIPA'S FINANCIAL ADVISOR

     Background. LIPA engaged Robinson-Humphrey to undertake the following on
behalf of LIPA in connection with the Merger: (1) to render a First Opinion at
or about the date of the Merger Agreement and a Second Opinion at or about the
date of this Proxy Statement/Prospectus to the Board of Directors of LIPA with
respect to the fairness, from a financial point of view, to LIPA's shareholders
of the consideration to be received in the Merger; and (2) to provide financial
advice concerning (a) the quality and value of the United Common Stock described
herein, (b) adjustments to the exchange ratio of the United Common Stock to be
received by LIPA's shareholders, and (c) the adequacy of the Merger
consideration in view of what other purchasers might be willing to pay for LIPA,
it having been understood that Robinson-Humphrey would not make a survey of
other purchasers upon which to base such advice.

     The terms of Robinson-Humphrey's engagement were set forth in a letter
agreement dated December 18, 1995 (the "Robinson-Humphrey Engagement Letter").
Under the terms of the Robinson-Humphrey Engagement Letter, LIPA agreed to pay
Robinson-Humphrey a fee of $150,000 payable upon delivery of the First Opinion
and a fee of $50,000 upon delivery of the Second Opinion. If LIPA had not
requested the Second Opinion, then the $50,000 fee would have been payable at
the time this Proxy Statement/Prospectus was mailed. If LIPA had broken off
negotiations with United or had not requested the First Opinion before March 31,
1996, then LIPA would have been obligated to pay Robinson-Humphrey an advisory
fee equal to $75,000. Upon subsequent delivery of the First Opinion, such
advisory fee would have been credited against the fee payable upon delivery of
such First Opinion. The Robinson-Humphrey Engagement Letter also provides that
LIPA will reimburse Robinson-Humphrey its reasonable out-of-pocket expenses up
to $15,000. LIPA has also agreed to indemnify Robinson-Humphrey and hold it
harmless against any and all losses, claims, damages or liabilities (together
with reimbursement of legal and other expenses incurred in defense of such
claims) to which Robinson-Humphrey may become subject arising in any manner out
of or in connection with the professional services, advice or opinions of
Robinson-Humphrey pursuant to its engagement by LIPA, unless it is finally
judicially determined that such losses, claims, damages or liabilities resulted
directly from the negligence or willful misconduct of Robinson-Humphrey or any
of its controlling persons, affiliates, directors, officers, employees or
agents, or any breach by Robinson-Humphrey of the Engagement Letter. If the
Merger is not sooner completed, Robinson-Humphrey's engagement by LIPA will
terminate on September 30, 1996.

                                      34

     As a part of its engagement, Robinson-Humphrey advised LIPA concerning
certain adjustments to the exchange ratio of United Common Stock for LIPA Common
Stock. See "The Merger--Effects of the Merger." Robinson-Humphrey advised LIPA
that these adjustments were important to provide limited protection of the
merger consideration to be received by LIPA shareholders against market
volatility in the price of United Common Stock. See "RISK FACTORS." The exchange
ratio adjustments agreed to in the Merger Agreement were arrived at as a result
of direct negotiations between United and Robinson-Humphrey.

     Robinson-Humphrey is a recognized investment banking firm and, as a
customary part of its investment banking activities, is regularly engaged in the
valuation of businesses and their securities in connection with mergers and
acquisitions, negotiated underwritings, private placements, and valuations for
corporate and other purposes. The Board of Directors of LIPA selected Robinson-
Humphrey primarily because of its expertise and reputation, and secondarily
because of its availability to complete the assignment on a timely basis and its
competitive pricing of the service.
    
     The Opinion. On January 9, 1996, and April 22, 1996, Robinson-Humphrey
delivered its First Opinion and Second Opinion, respectively, to LIPA's Board of
Directors that, as of such dates, the consideration to be received by the
shareholders of LIPA in the Merger was fair to such shareholders from a
financial point of view. No limitations were imposed by LIPA's Board of
Directors upon Robinson-Humphrey with respect to the investigations made or the
procedures followed by it in rendering its opinions, except that Robinson-
Humphrey was not authorized to, and did not, solicit any indications of interest
from any third party to acquire all or any part of LIPA.     

     Robinson-Humphrey has assumed that United is effectively acquiring 50% of
the operations of the Community Health Entities for $50,000,000, thereby
implying a value of approximately $100,000,000 for 100% of the Community Health
Entities. This assumption was necessitated, in part, by the fact that although,
historically, the Community Health Entities have been operated separately, with
each maintaining separate financial statements, the operations of the two
entities are related so inextricably that their historical and projected
financial results should be combined for purposes of analyzing them, evaluating
the value of LIPA's ownership interest in them and comparing them to other
companies. In preparation of the pro forma financial projections for the
Community Health Entities, Robinson-Humphrey consulted with members of
management of the Community Health Entities, as well as representatives from
LIPA and United.
    
     In rendering its opinions, Robinson-Humphrey reviewed and analyzed: (1) the
Merger Agreement; (2) financial and operating information with respect to the
business, operations and prospects of the Community Health Entities furnished to
Robinson-Humphrey by LIPA and the Community Health Entities; (3) a comparison of
the historical financial results and present financial condition of the
Community Health Entities with those of other companies which Robinson-Humphrey
deemed relevant; (4) an analysis of financial and stock market information of
selected publicly-traded companies which Robinson-Humphrey deemed comparable to
the Community Health Entities; (5) a comparison of the financial terms of the
Merger with the financial terms of certain other recent transactions which
Robinson-Humphrey deemed relevant; (6) analyses of the present value of the free
cash flows projected to be generated by the Community Health Entities during the
forecast period; and (7) certain information regarding United, including, among
others, (a) certain recent filings with the Commission, (b) equity research
reports published by analysts within the investment community who provide
research coverage of United, (c) the recent trading and volume history of
United's stock, and (d) historical and projected financial information of the
Louisiana HMO operations of MetraHealth acquired by United. In addition,
Robinson-Humphrey held discussions with the management of LIPA, the Community
Health Entities and United concerning their respective businesses and
operations, assets, present conditions and future prospects and undertook such
other studies, analyses and investigations as it deemed appropriate.     

                                       35
<PAGE>

     
     In rendering its opinions, Robinson-Humphrey assumed and relied upon,
without independent verification, the accuracy and completeness of the financial
and other information used by it. Robinson-Humphrey further relied upon the
assurances of the management of LIPA and the Community Health Entities that they
were not aware of any facts that would make such information inaccurate or
misleading. With respect to the financial forecasts provided to and discussed
with Robinson-Humphrey by the management of LIPA and the Community Health
Entities, Robinson-Humphrey assumed, with LIPA's approval, that (1) such
forecasts and projections were reasonably prepared on bases reflecting the best
currently available estimates and judgments of management as to the future
financial performance of the Community Health Entities; and (2) the Community
Health Entities would perform in accordance with such projections. Robinson-
Humphrey did not conduct a physical inspection of the properties and facilities
of the Community Health Entities, and did not make or obtain any evaluations or
appraisals of the assets or liabilities of the Community Health Entities.
Robinson-Humphrey's opinions were based upon market, economic and other
conditions as they existed, and which were capable of being evaluated, as of the
date of the opinions.

     THE FULL TEXT OF THE SECOND OPINION OF ROBINSON-HUMPHREY, DATED APRIL 22,
1996, WHICH SETS FORTH ASSUMPTIONS MADE AND MATTERS CONSIDERED, APPEARS AS
EXHIBIT B TO THIS PROXY STATEMENT/PROSPECTUS. LIPA'S SHAREHOLDERS ARE URGED TO
READ THIS OPINION IN ITS ENTIRETY. ROBINSON-HUMPHREY'S OPINION WAS DIRECTED ONLY
TO THE FAIRNESS, FROM A FINANCIAL POINT OF VIEW, OF THE CONSIDERATION TO BE
RECEIVED BY THE SHAREHOLDERS OF LIPA. ROBINSON-HUMPHREY'S OPINION WAS DELIVERED
FOR THE INFORMATION OF LIPA'S BOARD OF DIRECTORS AND DOES NOT CONSTITUTE A
RECOMMENDATION AS TO HOW ANY SHAREHOLDER SHOULD VOTE AT THE SPECIAL MEETING OR
ANY OTHER MEETING OF LIPA'S SHAREHOLDERS CALLED TO CONSIDER THE MERGER. THIS
SUMMARY OF THE OPINION OF ROBINSON-HUMPHREY IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO THE FULL TEXT OF SUCH OPINION.

     In connection with the preparation of its fairness opinions, Robinson-
Humphrey performed certain financial and comparative analyses, including those
described below. The summary set forth below includes all of the financial
analyses used by Robinson-Humphrey and deemed to be material but does not
purport to be a complete description of the analyses performed by Robinson-
Humphrey in arriving at its opinion. The preparation of a fairness opinion
involves various determinations as to the most appropriate and relevant methods
of financial analysis and the application of those methods to the particular
circumstances, and therefore, such an opinion is not readily susceptible to
summary description. Furthermore, in arriving at its fairness opinions, 
Robinson-Humphrey did not attribute any particular weight to any analysis or
factor considered by it, but rather made qualitative judgments as to the
significance and relevance of each analysis and factor. Accordingly, Robinson-
Humphrey believes its analyses must be considered as a whole and that
considering any portions of such analyses without considering all analyses and
factors could create a misleading or incomplete view of the process underlying
the opinion. In addition, analyses relating to the value of businesses do not
purport to be appraisals or to reflect the price at which businesses may
actually be sold. No public company used as a comparison is identical to the
Community Health Entities. An analysis of the results of such a comparison is
not mathematical; rather, it involves complex considerations and judgments
concerning differences in financial and operating characteristics of the
comparable companies and other factors that could affect the value of the
companies to which the Community Health Entities are being compared.

     The generally accepted financial analyses Robinson-Humphrey used in
reaching its fairness opinions included (1) comparison with selected publicly
traded companies, which consisted of reviewing market statistics and financial
and operating information with respect to selected companies considered to have
businesses similar to that of the Community Health Entities; (2) analysis of
selected merger transactions, which consisted of reviewing operating statistics
and purchase price information with respect to selected acquisitions of assets
or businesses similar to those of the Community Health Entities; and (3)
discounted cash flow analysis, which consisted of estimating the     

                                      36
<PAGE>

     
present value of the Community Health Entities' future free cash flows, under
various forecast assumptions provided by the management of LIPA and the
Community Health Entities. The material portions of these analyses (which are
all of the material valuation methodologies performed by Robinson-Humphrey) as
represented in its Second Opinion are summarized below.

     Comparison with Selected Companies. Robinson-Humphrey compared selected
financial data and market information for the Community Health Entities to the
corresponding financial data and market information for two groups of selected
public companies in the health care industry: (1) multi-market HMOs, and (2)
single market HMOs. Robinson-Humphrey used this analysis to derive implied
equity values (i.e., the value of the total equity of the Community Health
Entities implied by multiplying certain ratios derived from selected HMOs other
than the Community Health Entities by the Community Health Entities' own
financial data) for the Community Health Entities. This comparison showed, among
other things, that (1) the mean ratio of price to earnings for the last 12
months was 20.6x for the multi-market HMOs, 14.6x for the single market HMOs and
18.3x for all HMOs; (2) the mean ratio of price to projected calendar 1996
earnings was 18.4x for multi-market HMOs, 13.6x for single market HMOs and 16.6x
for all HMOs; (3) the mean ratio of price to projected calendar 1997 earnings
was 14.1x for multi-market HMOs, 11.0x for single market HMOs and 13.1x for all
HMOs; (4) the mean ratio of market value to book value was 3.5x for multi-market
HMOs, 2.1x for single market HMOs and 3.0x for all HMOs; (5) the mean ratio of
firm value (firm value equals equity value plus total debt less cash) to
revenues for the last 12 months was 1.1x for multi-market HMOs, 0.7x for single
market HMOs and 0.8x for all HMOs; (6) the mean ratio of firm value to earnings
before interest and tax ("EBIT") for the last 12 months was 13.1x for multi-
market HMOs, 11.2x for single market HMOs and 12.4x for all HMOs; and (7) the
mean ratio of firm value to earnings before interest, depreciation and
amortization ("EBITDA") for the last 12 months was 12.0x for multi-market HMOs,
8.7x for single market HMOs and 10.6x for all HMOs. Robinson-Humphrey also
calculated a value per member of $1,169 for multi-market HMOs, $803 for single
market HMOs and $930 for all HMOs. Based upon these values and these and other
multiples, Robinson-Humphrey calculated an average implied equity value for the
Community Health Entities based on multi-market HMOs of $77,548,000, with a
median value of $72,027,000, an average implied equity value for the Community
Health Entities based on single market HMOs of $56,046,000, with a median value
of $54,728,000, and an average implied equity value for the Community Health
Entities based on all HMOs of $67,356,000, with a median value of $65,884,000.

     Analysis of Selected Merger Transactions. Robinson-Humphrey analyzed 23
mergers and acquisitions occurring since March 1993 involving health care
companies. Some of these transactions involved United. In each such acquisition,
Robinson-Humphrey calculated the implied equity value as a multiple of earnings
for the last 12 months and latest book value, as well as the implied firm value
as a multiple of revenues for the last 12 months, EBIT for the last 12 months,
EBITDA for the last 12 months and latest membership. The resulting average
multiples were as follows: earnings, 29.2x; book value, 5.7x; revenues, 1.08x;
EBIT, 17.6x; EBITDA, 13.5x, membership, $1,144. Based upon the multiples for
these transactions, Robinson-Humphrey calculated an average implied equity value
of $67,832,000 and a median implied equity value of $38,382,000 for the
Community Health Entities. Robinson-Humphrey then identified one of these 23
transactions which was a pending acquisition by United and compared the purchase
price multiples in this transaction with the corresponding multiples for the
Merger (in parenthesis): earnings, 19.7x (72.7x); revenues, .93x (.72x); EBITDA,
14.6x (47.1x); EBIT, 17.2x (63.7x); membership, $1,188 ($919); and book value,
5.3x (15.5x).

     Discounted Cash Flow Analysis. Using a discounted cash flow analysis,
Robinson-Humphrey estimated the present value of the equity of the Community
Health Entities based upon projected cash flows through the year 2000. Terminal
values were calculated by applying projected EBITDA and EBIT in the year 2000 to
a range of multiples from 6.0x to 9.0x and 8.0x to 11.0x, respectively. The
terminal values were discounted to present value using a range of discount rates
(from 15% to 25%). These values were combined with the present value of the net
cash flows (also discounted using a range of discount    

                                      37
<PAGE>

     
rates from 15% to 25%) and then adjusted for the estimated value of pro forma
net debt as of March 31, 1996, resulting in a range of implied equity values
based on each operating scenario. The calculations, based on a range of EBITDA
multiples of 6.0x to 9.0x projected EBITDA in the year 2000, resulted in a mean
implied equity value in the base case of $72,050,000 and a median implied equity
value of $70,803,000 for the Community Health Entities. The calculations, based
on a range of EBIT multiples of 8.0x to 11.0x projected EBIT in the year 2000,
resulted in a mean implied equity value in the base case of $82,851,000 and a
median implied equity value of $81,353,000 for the Community Health 
Entities.     
    
     Summary and Conclusion. As described above, both average and median implied
equity values derived by comparisons to both single market and multiple market
HMO companies were lower than the indicated value in the Merger as calculated by
Robinson-Humphrey. Furthermore, both average and median implied equity values
derived by comparison to selected merger transactions were lower than the
indicated value in the Merger. Also, the mean and median implied equity values
derived by discounted cash flow analysis under the base case set of projections
were lower than the indicated value in the Merger. In rendering its opinion,
Robinson-Humphrey did not rely solely on these analyses and reviewed and
analyzed all of the information enumerated above under "The Opinion" and relied
upon the assumptions described therein. Based upon and subject to the foregoing,
Robinson-Humphrey concluded that, as of the date of the Second Opinion, from a
financial point of view, the consideration to be received in the Merger by the
holders of LIPA Common Sotck is fair to such shareholders.    
INTERESTS OF CERTAIN PERSONS IN THE MERGER
    
     Pursuant to the Merger Agreement, and as a condition to the closing of the
Merger, UHC Management Company, Inc., a wholly owned subsidiary of United (now
known as United Health Services, Inc.), has entered into consulting agreements
with each of V. Lynn McCord, President of LIPA, Kenneth C. Cranor, Chairman of
the LIPA Board, Williams D. Wall, IV, Vice President of LIPA, and Thomas H.
Benton, counsel for LIPA, (the "Managers"). These agreements (the "Manager
Agreements"), each of which has a three-year term, provide that each Manager
will provide the following consulting services to United: (1) to assist in
maintaining provider relations and to advise United regarding improvements in
CHN's operations; (2) upon request of United, to continue (except in the case of
Mr. Benton) to provide health care services and to encourage physicians and
other providers to participate in, or to maintain participation in, the CHN
provider networks; and (3) upon request of United, to serve on the Board of
Directors of CHN or related entities and/or to serve on committees of CHN.
Annual compensation under the Manager Agreements is as follows: Dr. McCord--
$80,000; Dr. Cranor--$80,000; Dr. Wall--$80,000; and Mr. Benton--$60,000.     

     The Manager Agreements prohibit the Managers from disclosing any
confidential information regarding United that may become known to the Managers.
The Manager Agreements also contain non-solicitation and non-competition
provisions, pursuant to which each Manager agrees not (1) to hire away or
attempt to hire away any then-current employees of CHN or UHC or persuade any
such employee to leave the employ of CHN or UHC; (2) to solicit, divert, or take
away, or attempt to solicit, divert, or take away the business of any person or
entity with whom CHN has established or is actively seeking to establish a
business or customer relationship within Louisiana; and, except in the case of
Thomas H. Benton, (3) without United's prior written consent, to assume a
management position in any HMO or Blue Cross/Blue Shield of Louisiana operation
competing with CHN in Louisiana, it being expressly recognized that each Manager
will remain free to provide personal medical services for and contract as a
medical provider with any such HMO or Blue Cross/Blue Shield of Louisiana
operation. The Manager Agreements further provide that such obligations shall be
waived to the extent they may conflict with the performance of the duties of a
Manager as a Shareholder Representative. See "THE MERGER--Contingent Payment
Rights" and "THE MERGER AGREEMENT--Indemnification."

                                      38
<PAGE>

     UHC has also entered into consulting agreements with nine persons who have
served on the boards of directors of LIPA and CHN and 20 shareholders of LIPA
who serve on various committees of CHN. The service, confidentiality, non-
solicitation and non-competition confidentiality provisions in such agreements
are comparable to the consulting agreements with the Managers, and the term of
each of these agreements is two years. Annual compensation under the agreements
with each director is as follows: Dr. Harold Brandt--$20,000; Dr. Edward
Chiasson--$25,000; Dr. William J. Dimattia--$20,000; Dr. Henry Wade Giles--
$20,000; Dr. James Lanasa--$20,000; Dr. C. W. Lovell III--$20,000; Dr. Henry D.
Olinde--$20,000; Dr. Charles P. Raborn--$25,000; Dr. Edwin Walker--$20,000.

     In addition to the director fees customarily paid to directors for
attendance at meetings of the LIPA Board, (1) all members of the LIPA Board have
received payments of $5,000 per director and (2) Dr. V. Lynn McCord, Dr. Kenneth
C. Cranor and Dr. Williams D. Wall, IV, as members of the Committee, each
received in addition to the $5,000 payment a payment of $20,000, in all cases as
compensation for additional services to LIPA in connection with the Merger
rendered outside of meetings of the LIPA Board. The additional services
included, among other things, extensive review of documents prepared in
connection with the Merger, attendance at informational meetings, and review of
materials and reports prepared by LIPA's advisors.

MANAGEMENT OF SURVIVING CORPORATION AFTER THE MERGER

     United Sub will be the Surviving Corporation of the Merger and will be a
wholly owned subsidiary of United. The directors of United Sub immediately prior
to the Effective Time will be the initial directors of the Surviving
Corporation, and the officers of United Sub immediately prior to the Effective
Time will be the initial officers of the Surviving Corporation. United currently
expects that, after the Effective Time, it will retain most of the executive
officers of LIPA's operational subsidiaries immediately prior to the Effective
Time, with duties substantially similar to those that such executive officers
are currently performing.

     CHN and United HealthCare South, Inc. ("UHCS") a wholly-owned subsidiary of
United, have agreed to the terms of a Management Agreement to become effective
at the Effective Time. This Agreement calls for CHN to pay UHCS a management fee
based upon a percentage of CHN's gross revenues. The effectiveness of the
Management Agreement is contingent upon approval of such agreement by the
Louisiana Department of Insurance.

ACCOUNTING TREATMENT

     United intends to treat the Merger as a purchase for accounting and
financial reporting purposes. Under this method of accounting, United will
allocate the purchase price to the assets it acquires and liabilities it assumes
based on their estimated fair values at the date of acquisition.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     United and LIPA expect that the Merger will be treated as a tax-free
reorganization within the meaning of Section 368(a) of the Code and that for
federal income tax purposes no gain or loss will be recognized by any
shareholder of LIPA Common Stock upon the receipt of United Common Stock for
LIPA Common Stock pursuant to the Merger (except to the extent that (1) a
Contingent Payment Right is taxable immediately upon its receipt by a
shareholder of LIPA Common Stock and (2) any cash is ultimately received by a
shareholder of LIPA Common Stock in connection with (a) the receipt of a
fractional share interest in United Common Stock, or (b) on account of a
Contingent Payment Right). The Internal Revenue Service (the "Service") has not
been and will not be asked to rule upon the tax consequences of the Merger.
Instead, LIPA and United will rely upon the opinion of Dorsey & Whitney LLP,
counsel to United, as to certain federal income tax consequences of the Merger.
Such opinion will be 

                                      39
<PAGE>



based upon facts described therein and upon certain assumptions and
representations that will be made by LIPA and United. The opinion of Dorsey &
Whitney LLP will be based upon the Code, the Regulations promulgated thereunder,
current administrative rulings and practice and judicial authority, all of which
are subject to change. An opinion of counsel is not binding on the Service and
there can be no assurance, and none is hereby given, that the Service will not
take a position contrary to one or more positions reflected in such opinion or
that such opinion will be upheld by the courts if challenged by the Service.
EACH LIPA SHAREHOLDER IS URGED TO CONSULT WITH HIS OR HER OWN TAX ADVISOR
CONCERNING THE FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER, AS WELL AS ANY
APPLICABLE STATE, LOCAL, FOREIGN OR OTHER TAX CONSEQUENCES, BASED UPON SUCH
SHAREHOLDER'S OWN PARTICULAR FACTS AND CIRCUMSTANCES.

     The obligations of each of LIPA and United to consummate the Merger is
conditioned on, among other things, the receipt by LIPA and United of the
opinion of Dorsey & Whitney LLP, which will be based upon facts and
representations to be provided to such firm, and subject to various assumptions
and qualifications, substantially to the effect that the Merger will qualify as
a "reorganization" under Section 368(a) of the Code. On the basis of the
foregoing opinion, it is expected that the following material federal income tax
consequences will result from the Merger:

     (1) No gain or loss will be recognized by United, LIPA, or United Sub as a
result of the Merger;

     (2) No gain or loss will be recognized by any LIPA shareholder upon the
exchange of LIPA Common Stock for United Common Stock pursuant to the Merger
(except to the extent that (a) a Contingent Payment Right is taxable immediately
upon its receipt by a shareholder of LIPA Common Stock and (b) any cash is
ultimately received by a shareholder of LIPA Common Stock in connection with (i)
the receipt of a fractional share interest in United Common Stock, or (ii) on
account of a Contingent Payment Right);

     (3) The tax basis of the United Common Stock received by a LIPA shareholder
who exchanges LIPA Common Stock for United Common Stock will be the same as the
basis of the LIPA Common Stock surrendered in exchange therefor (subject to any
current or future adjustments required as the result of (a) the receipt of a
Contingent Payment Right and (b) the receipt of cash (i) in lieu of a fractional
share of United Common Stock or (ii) on account of a Contingent Payment Right);

     (4) The holding period of the United Common Stock received by a LIPA
shareholder receiving United Common Stock will include the period during which
the LIPA Common Stock surrendered in exchange therefor was held (provided that
the LIPA Common Stock of such LIPA shareholder was held as a capital asset at
the Effective Date); and

     (5) A LIPA shareholder who exchanges LIPA Common Stock for cash in lieu of
receiving a fractional share interest of United Common Stock will be treated as
though such cash was received as a distribution in full payment in exchange for
the fractional share interest of United Common Stock which the LIPA shareholder
would otherwise be entitled to receive, and will qualify as capital gain or loss
(assuming the LIPA Common Stock exchanged was a capital asset in the
shareholder's hands as of the Effective Date).

     The opinion described above will be based upon certain assumptions,
including, but not limited to, the assumption that the shareholders of LIPA do
not have any plan or intention to dispose, sell, exchange or otherwise dispose
of a number of shares of United Common Stock received pursuant to the Merger
that would reduce the ownership by such shareholders of LIPA of United Common
Stock to a number of shares having a value, as of the date of the Merger, which
is less than 50 percent of the value of all of the formerly outstanding LIPA
Common Stock held by such LIPA shareholders as of the same date. Moreover, if
such required tax opinion is not received, the Merger will not be consummated
unless 

                                      40
<PAGE>

the conditions requiring its receipt are waived and the approvals of United and
LIPA shareholders are resolicited by means of an updated Proxy
Statement/Prospectus.
    
     In addition, (1) the possibility exists that a former LIPA shareholder may
be taxed immediately upon the receipt of the Contingent Payment Rights; and (2)
to the extent not taxable immediately, it is expected that gain, if any, but not
loss, will be recognized by former LIPA shareholders who, after the Effective
Time and within 150 days following the end of each of the years ended December
31, 1996, and December 31, 1997, receive cash payments from United in connection
with the Contingent Payment Rights issued pursuant to the Merger. If the initial
receipt of the Contingent Payment Rights (assuming the value of such Rights are
in fact taxable at that time) or the receipt of cash in connection with the
Contingent Payment Rights does not have the effect of the distribution of a
dividend (as described below), then all of the gain recognized (other than
certain interest income as described below) would be capital gain, provided that
a LIPA shareholder held their LIPA Common Stock as a capital asset as of the
Effective Time.     
 
     The amount of gain that might be immediately recognized by a former LIPA
shareholder upon the initial receipt of the Contingent Payment Rights may be
equal to, but not in excess of, the total value of the Contingent Payment Rights
and any other cash received (such as cash received in lieu of a fractional share
of United Common Stock). United does not expect to undertake any tax reporting
in connection with the Merger on the basis that the initial receipt of the
Contingent Payment Rights is taxable immediately.

     Assuming the initial receipt of the Contingent Payment Rights are not
taxable, the amount of gain that would be recognized upon the eventual receipt
of cash pursuant to the Contingent Payment Rights, will be equal to the lesser
of (1) the amount of cash received or (2) the difference, if any, between the
fair market value of the United Common Stock, plus the value of the cash
received, and the former LIPA shareholder's adjusted tax basis in their newly
acquired United Common Stock. As of the Effective Time, the adjusted tax basis
of a former LIPA shareholder in their newly acquired shares of United Common
Stock will be equal to the total cost of acquiring their original shares of LIPA
Common Stock (plus or minus any required adjustments that relate to events
occurring prior to the Effective Time) plus or minus certain other basis
adjustments arising out of the Merger which are, at least in part, a function
of: (1) the amount of cash received in lieu of a fractional share of United
Common Stock; and (2) the amount of cash, if any, that is received in connection
with the Contingent Payment Rights.

     As a result of the cash that may ultimately be received in connection with
the Contingent Payment Rights, it is possible that a former LIPA shareholder's
basis in their newly acquired shares of United Common Stock would have to be
adjusted downward to reflect the entire amount of cash that could potentially be
received under such Rights. As a result, if a former LIPA shareholder sold
shares of United Common Stock, it is possible that the amount of gain associated
with the sale of such shares would be greater than the gain that would be
recognized if something less than the maximum amount of cash that could
potentially be received in connection with the Contingent Payment Rights were
taken into account as of the Effective Time. If a former LIPA shareholder's
basis in their newly acquired shares of United Common Stock is adjusted as
described above and less than such maximum amount of cash is ultimately
received, a former LIPA shareholder should be able to make appropriate
adjustments in the recognition of income or the tax basis of other shares of
United Common Stock in order to properly reflect the correct amount of gain to
be reported. The methods to be used in making such adjustments are, however,
uncertain.

     The determination of whether or not the receipt of cash by a former LIPA
shareholder in connection with payments received pursuant to a Contingent
Payment Right has the effect of a distribution of a dividend will be made, on a
shareholder by shareholder basis, by applying the rules of Section 302 of the
Code and by comparing the proportionate, percentage interest of a former LIPA
shareholder in United after the Merger with the proportionate, percentage
interest such shareholder 

                                      41
<PAGE>

would have had if such shareholder had received solely United Common Stock
pursuant to the Merger. This comparison is made as though United had issued in
the Merger to such shareholder solely its United Common Stock and, in the course
of undertaking a hypothetical redemption, had then redeemed such portion of its
United Common Stock at the time of the Merger for the amount of cash the
shareholder actually received pursuant thereto. In making this comparison, there
must be taken into account (1) any other shares of United Common Stock actually
owned by such LIPA shareholder, and (2) any such shares considered to be owned
by such shareholder by reason of the constructive ownership rules set forth in
Section 318 of the Code. These constructive ownership rules apply in certain
specified circumstances to attribute ownership of shares of a corporation from
the shareholder actually owning the shares, whether an individual, trust,
partnership or corporation, to certain members of such individual's family or to
certain other individuals, trusts, partnerships or corporations. Moreover, under
these rules, a shareholder is also considered to own any shares with respect to
which a shareholder holds exercisable stock options.
 
     Finally, as previously mentioned above, a certain portion of any cash
received by a former LIPA shareholder in connection with a subsequent payment
made by United pursuant to a Contingent Payment Right will constitute interest
income pursuant to the provisions of Sections 483 or 1275 of the Code. In turn,
under Sections 483 or 1275 of the Code and the relevant Treasury Regulations
promulgated thereunder, the amount of any gain that will be characterized as
interest income is a function of the actual amount of cash ultimately received
by a former LIPA shareholder and the prevailing short-term applicable federal
interest rate as of the Effective Time. Specifically, any cash received will be
discounted by the applicable rate to determine both a principal and interest
component, such that the interest component will be taxed as interest income,
while the principal component will be taxed in accordance with the provisions of
the Code described above.

     Pursuant to applicable Internal Revenue Service guidelines, a hypothetical
redemption, as described above, involving a holder of a minority interest in
United whose relative stock interest in United is minimal, who exercises no
control over the affairs of United and who experiences a reduction in the
shareholder's proportionate, percentage interest in United, both directly and by
application of the foregoing constructive ownership rules, generally will not be
deemed to have resulted in the distribution of a dividend under the rules set
forth in Section 302(b)(1) of the Code. Accordingly, in the case of a LIPA
shareholder with a large amount of unrealized appreciation inherent in their
holdings of LIPA Common Stock, it is likely that any cash payment received
pursuant to a Contingent Payment Right will be taxable in full only upon its
receipt, and will be characterized, in part, as interest income and, in part, as
capital gain.

      BECAUSE THE DETERMINATION OF (1) WHETHER CASH RECEIVED PURSUANT TO THE
MERGER WILL BE TREATED AS THE DISTRIBUTION OF A DIVIDEND, (2) THE TAX BASIS AND
ADJUSTMENTS THERETO OF UNITED COMMON STOCK RECEIVED PURSUANT TO THE MERGER, (3)
THE POSSIBILITY THAT THE RECEIPT OF THE CONTINGENT PAYMENT RIGHTS ARE
IMMEDIATELY TAXABLE, AND (4) THE EXTENT TO WHICH A FORMER LIPA SHAREHOLDER MUST
ULTIMATELY RECOGNIZE GAIN UPON THE RECEIPT OF CASH PURSUANT TO THE CONTINGENT
PAYMENT RIGHTS, IS UNCERTAIN AND MAY DEPEND UPON THE FACTS AND CIRCUMSTANCES
PECULIAR TO EACH LIPA SHAREHOLDER, SUCH SHAREHOLDERS ARE STRONGLY ADVISED TO
CONSULT WITH THEIR OWN TAX ADVISERS REGARDING THESE TAX CONSEQUENCES OF THE
MERGER.

     The foregoing is only a general description of certain anticipated federal
income tax consequences of the Merger, without regard to the particular facts
and circumstances of the tax situation of each shareholder of LIPA. It does not
discuss all of the consequences that may be relevant to shareholders of LIPA
entitled to special treatment under the Code (such as insurance companies,
dealers in securities, exempt organizations or foreign persons) or to
shareholders of LIPA who acquired their LIPA Common Stock pursuant to the
exercise of employee stock options or otherwise as compensation. Moreover, the
summary set forth above does not purport to be a complete analysis of all
potential tax effects of the transactions contemplated by the Merger Agreement
or the Merger itself, 

                                      42
<PAGE>

and no information is provided herein with respect to the tax consequences, if
any, of the Merger under state, local, foreign or other tax laws.

STOCK EXCHANGE LISTING

     United has agreed that the United Common Stock to be issued pursuant to the
Merger will be approved for listing on the NYSE, subject to official notice of
issuance. An application will be made for listing such United Common Stock on
the NYSE.

DISSENTERS' RIGHTS OF APPRAISAL

     Unless the Merger Agreement is approved by the holders of at least 80% of
outstanding LIPA Common Stock, Section 131 of the LBCL, a copy of which is
included as Exhibit C to this Proxy Statement/Prospectus, allows a shareholder
of LIPA who objects to the Merger Agreement and who strictly complies with the
provisions of that section to dissent from the Merger Agreement and to have paid
to him or her in cash the fair cash value of his or her shares of LIPA Common
Stock as of the day before the Special Meeting, as determined by agreement
between the shareholder and United or by the District Court for the Parish of
East Baton Rouge if the shareholder and United are unable to agree.

     To exercise the right of dissent, a LIPA shareholder (1) must file with
LIPA a written objection to the Merger Agreement prior to or at the Special
Meeting and (2) must also vote his or her shares (in person or by proxy) against
the Merger Agreement at such Meeting. Neither a vote against the Merger
Agreement nor a specification in a proxy to vote against the Merger Agreement
will in and of itself constitute the necessary written objection to the Merger
Agreement. Moreover, by voting in favor of, or abstaining from voting on, the
Merger Agreement, or by returning the enclosed proxy without instructing the
proxy holders to vote against the Merger Agreement, a shareholder waives his or
her rights under Section 131. The right to dissent may be exercised only by the
record owners of the shares and not by persons who hold shares only
beneficially. Beneficial owners who wish to dissent to the Merger Agreement
should have the record ownership of the shares transferred to their names or
instruct the record owner to follow the Section 131 procedure on their behalf.

     If the Merger Agreement is approved by less than 80% of the total number of
shares of LIPA Common Stock outstanding, then promptly after the Effective Date
written notice of the consummation of the Merger Agreement will be given by
United by registered mail to each former shareholder of LIPA who filed a written
objection to the Merger Agreement and voted against it at such shareholder's
last address on LIPA's records. Within 20 days after the mailing of such notice,
the shareholder must file with United a written demand for payment for his or
her shares at their fair cash value as of the day before the Special Meeting and
must state the amount demanded and a post office address to which United may
reply. Such shareholder must also deposit the certificates formerly representing
his or her shares of LIPA Common Stock in escrow with a bank or trust company
located in East Baton Rouge Parish, Louisiana. The certificates must be duly
endorsed and transferred to United upon the sole condition that they be
delivered to United upon payment of the value of the shares in accordance with
Section 131. With the above-mentioned demand, the shareholder must also deliver
to United the written acknowledgment of such bank or trust company that it holds
the certificate(s), duly endorsed as described above.

     Unless the shareholder objects to and votes against the Merger Agreement,
demands payment, endorses and deposits his certificates and delivers the
required acknowledgment in accordance with the procedures and within the time
periods set forth above, the shareholder will conclusively be presumed to have
acquiesced to the Merger Agreement and will forfeit any right to seek payment
pursuant to Section 131.

                                      43
<PAGE>

     If United does not agree to the amount demanded by the shareholder, or does
not agree that payment is due, it will, within 20 days after receipt of such
demand and acknowledgment, notify such shareholder in writing at the designated
post office address of either (1) the value it will agree to pay or (2) its
belief that no payment is due. If the shareholder does not agree to accept the
offered amount, or disagrees with United's assertion that no payment is due, he
or she must, within 60 days after receipt of such notice, file suit against
United in the District Court for the Parish of East Baton Rouge for a judicial
determination of the fair cash value of the shares. Any shareholder entitled to
file such suit may, within such 60-day period but not thereafter, intervene as a
plaintiff in any suit filed against United by another former shareholder for a
judicial determination of the fair cash value of such other shareholder's
shares. If a shareholder fails to bring or to intervene in such a suit within
the applicable 60-day period, such shareholder will be deemed to have consented
to accept United's statement that no payment is due or, if United does not
contend that no payment is due, to accept the amount specified by United in its
notice of disagreement.

     If upon the filing of any such suit or intervention, United deposits with
the court the amount, if any, which it specified in its notice of disagreement,
and if in that notice United offered to pay such amount to the shareholder on
demand, then the costs (not including legal fees) of the suit or intervention
will be taxed against the shareholder if the amount finally awarded to him or
her, exclusive of interest and costs, is equal to or less than the amount so
deposited; otherwise, the costs (not including legal fees) will be taxed against
United.

     Upon filing a demand for the value of his or her shares, a shareholder
ceases to have any rights of a shareholder except the rights created by Section
131. The shareholder's demand may be withdrawn voluntarily at any time before
United gives its notice of disagreement, but thereafter only with the written
consent of United. If the demand is properly withdrawn, or if the shareholder
otherwise loses his or her dissenters' rights, the shareholder will be restored
to his or her rights as a shareholder as of the time of filing of his or her
demand for fair cash value.

     Until the Effective Date, dissenting shareholders of LIPA should send any
communications regarding their rights to Louisiana Independent Physicians
Association, Inc., c/o Emile Provost, 8550 United Plaza Boulevard, Suite 600,
Baton Rouge, Louisiana 70809. After the Effective Date, dissenting shareholders
should send any communications regarding their rights to United HealthCare
Corporation, 9900 Bren Road East, Minnetonka, Minnesota 55343, Attention:
General Counsel. All such communications should be signed by or on behalf of the
dissenting shareholder in the form in which his or her shares are registered on
the books of LIPA.

     Shareholders who receive cash for the fair value of their shares of LIPA
Common Stock upon the exercise of dissenters' rights will realize taxable gain
or loss for federal income tax purposes. EACH SHAREHOLDER OF LIPA IS URGED TO
CONSULT WITH HIS OR HER OWN PERSONAL TAX AND FINANCIAL ADVISORS CONCERNING
FEDERAL INCOME TAX CONSEQUENCES OF THE EXERCISE OF DISSENTERS' RIGHTS, AS WELL
AS ANY APPLICABLE STATE, LOCAL, FOREIGN OR OTHER TAX CONSEQUENCES, BASED UPON
SUCH SHAREHOLDER'S OWN PARTICULAR FACTS AND CIRCUMSTANCES.

     The foregoing summary of Section 131 does not purport to be complete and is
qualified in its entirety by reference to Section 131, a copy of which is
included as Exhibit C to this Proxy Statement/Prospectus and incorporated herein
by reference. All shareholders of LIPA are urged to read Section 131 in its
entirety.

REGULATORY APPROVALS

     Under the HSR Act and the rules promulgated thereunder by the Federal Trade
Commission (the "FTC"), certain acquisition transactions may not be consummated
unless notice has been given and certain information has been furnished to the
Antitrust Division of the United States Department of

                                      44
<PAGE>

Justice (the "Antitrust Division") and the FTC and certain waiting period
requirements have been satisfied. The Merger is subject to these requirements.

     United and LIPA each filed with the Antitrust Division and the FTC a
Notification and Report Form with respect to the Merger on January 25, 1996.
Under the HSR Act, the Merger may not be consummated until the expiration of a
waiting period of at least 30 days following the receipt of the amended filings,
unless the waiting period is earlier terminated by the FTC and the Antitrust
Division. The waiting period expired on February 25, 1996.

     The FTC and the Antitrust Division frequently scrutinize the legality of
transactions such as the Merger under the antitrust laws. At any time before or
after the Effective Time, the FTC or the Antitrust Division could take such
action under the antitrust laws as it deems necessary or desirable in the public
interest, including seeking to enjoin the Merger or seeking the divestiture of
LIPA by United, in whole or in part, or the divestiture of substantial assets of
United, LIPA or their respective subsidiaries. State Attorneys General and
private parties may also bring legal actions under the federal or state
antitrust laws under certain circumstances. Based upon an examination of
information available to United and LIPA relating to the businesses in which
United, LIPA and their respective subsidiaries are engaged, United and LIPA
believe that the consummation of the Merger will not violate the antitrust laws.
Nevertheless, there can be no assurance that a challenge to the proposed Merger
on antitrust grounds will not be made or, if such a challenge is made, that
United and LIPA will prevail.
    
     In addition, the consummation of the Merger will require the prior approval
of, or the furnishing of notice to, the appropriate regulatory authorities in
Louisiana, the state in which LIPA owns an interest in an HMO. On or about March
13, 1996, United filed a Form A application with the Louisiana Department of
Insurance seeking approval of the change in control effected pursuant to the
Merger. On or about March 16, 1996, Community Health Network of Louisiana, Inc.
filed a material modification notice with the Louisiana Department of Insurance.
Material modification notices are required to be filed when there are certain
changes in the operations of an HMO, including a change of ten percent or more
of the ownership of the health maintenance organization. If the commissioner of
insurance does not disapprove the proposed modification within thirty days of
filing, or request a thirty day extension in writing, the modification shall be
deemed approved.    

     Neither United nor LIPA is aware of any other material governmental
approvals or actions that may be required for consummation of the Merger except
as described above. Should any such approval or action be required, it is
presently contemplated that such approval or action would be sought. There can
be no assurance, however, that any such approval or action, if needed, could be
obtained and would not be conditioned in a manner that would cause the parties
to abandon the Merger.

RESALES OF UNITED COMMON STOCK ISSUED IN THE MERGER

     United Common Stock to be issued to shareholders of LIPA in connection with
the Merger has been registered under the Securities Act. United Common Stock
received by shareholders of LIPA upon consummation of the Merger will be freely
transferable under the Securities Act except for shares issued to any person who
may be deemed to be an "Affiliate" (as defined below) of LIPA or United within
the meaning of Rule 145 under the Securities Act. "Affiliate" is generally
defined as a person who controls, is controlled by, or is under common control
with LIPA or United at the time of the Special Meeting (generally, directors,
certain executive officers and major shareholders). Affiliates of LIPA or United
may not sell their shares of United Common Stock acquired in connection with the
Merger, except pursuant to an effective registration statement under the
Securities Act covering such shares or in compliance with Rule 145 or another
applicable exemption from the registration requirements of the Securities Act.
In general, under Rule 145, for two years following the Effective Time, an
Affiliate (together with certain related persons) would be entitled to sell
shares of United Common Stock

                                      45
<PAGE>
    
acquired in connection with the Merger only through unsolicited "broker
transactions" or in transactions directly with a "market maker," as such terms
are defined in Rule 144 under the Securities Act. Additionally, the number of
shares to be sold by an Affiliate (together with certain related persons and
certain persons acting in concert) during such two-year period within any three-
month period for purposes of Rule 145 may not exceed the greater of 1% of the
outstanding shares of United Common Stock or the average weekly trading volume
of such stock during the four calendar weeks preceding such sale. Rule 145 would
remain available to Affiliates only if United remained current with its
informational filings with the Commission under the Exchange Act. Two years
after the Effective Time, an Affiliate would be able to sell such United Common
Stock without such manner of sale or volume limitations, provided that United
was current with its Exchange Act informational filings and such Affiliate was
not then an affiliate of United. Three years after the Effective Time, an
Affiliate would be able to sell such shares of United Common Stock without any
restrictions so long as such Affiliate had not been an affiliate of United for
at least three months prior thereto.

                             THE MERGER AGREEMENT

THE MERGER AGREEMENT

     The following is a brief summary of the material provisions of the Merger
Agreement. This description does not purport to be complete and is qualified in
its entirety by reference to the Merger Agreement included as Exhibit A to this
Proxy Statement/Prospectus and incorporated herein by reference. All
shareholders are urged to read the Merger Agreement in its entirety. See also
"THE MERGER."

GENERAL

     The Merger Agreement provides that, upon the satisfaction or waiver of
certain conditions, LIPA will be merged with and into United Sub, United Sub
will continue as the Surviving Corporation, and the separate existence of LIPA
will cease. Pursuant to the Merger Agreement, at the Effective Time the LIPA
Common Stock outstanding, other than Dissenting Stock, will be converted into
the right to receive a pro rata allotment of an aggregate number of shares of
United Common Stock, equal in value to $50,000,000 divided by the Average Stock
Price; provided, however, that the number of shares issuable in the Merger will
be fixed at (1) 938,692 if the Average Stock Price is at least $49.2707 but less
than $53.2656, or (2) 730,093 if the Average Stock Price is more than $68.4844
but not more than $73.0500. If the Average Stock Price is more than $73.0500,
the number of shares issuable in the Merger will be (1) $53,750,000 divided by
(2) the Average Stock Price. If the Average Stock Price is less than $49.2707,
the number of shares issuable in the Merger will be (1) $46,250,000 divided by
(2) the Average Stock Price.

     In addition to United Common Stock, at the effective time of the Merger
each share of LIPA Common Stock outstanding, other than Dissenting Stock, will
receive one Contingent Payment Right to receive two contingent cash payments,
collectively, the Earn-Outs, net of any amount to which United is entitled
pursuant to the indemnification provisions of the Merger Agreement. The Earn-
Outs will be determined by reference to the Adjusted Net Income of the Community
Health Entities and MetraHealth Louisiana. For the period January 1, 1996 to
December 31, 1996, the Earn-Out will equal the amount by which Adjusted Net
Income exceeds $10.0 million, multiplied by 6.3. For the period January 1, 1997
to December 31, 1997, the Earn-Out will equal the amount by which Adjusted Net
Income exceeds $16.5 million, multiplied by 4.5. In no case, however, can the
aggregate of the two Earn-Outs exceed $35.0 million (or approximately $84,000
per share of LIPA Common Stock). The amount payable to each holder of a
Contingent Payment Right will be equal to the Earn-Out for the applicable year
divided by the number of Contingent Payment Rights outstanding at the time
payment is due.

LIMITATIONS ON NEGOTIATIONS BY LIPA

not to take any such action. LIPA shall promptly notify United (1) if any
inquiries, or proposals or requests for information concerning a Competing
Transaction are received by LIPA or any of its respective officers or directors,
or (2) when LIPA becomes aware that any such inquiries or proposals have been
received by LIPA's investment bankers, financial advisors, attorneys,
accountants, other representatives or shareholders.

INDEMNIFICATION

     Subject to certain limitations, United and its officers, directors,
employees and agents (collectively, the "United Indemnified Parties") shall,
from and after the Effective Time, be indemnified and held harmless against any
loss, liability, tax (including interest and penalties), damage or expense
(including reasonable legal expenses and costs) or any assertion thereof
("Losses"), which any United Indemnified Party may suffer, sustain or become
subject to as a result of (1) certain representations and warranties by LIPA in
the Merger Agreement that are not true and correct as of the date made, (2) any
breach of any covenant or agreement of LIPA contained in the Merger Agreement
that is required to be performed prior to the Effective Time , (3) certain
claims by a person who held shares of LIPA Common Stock prior to the Effective
Time relating to a breach of fiduciary duty or other improper action, (4)
certain claims for indemnification by officers and directors of LIPA, (5)
certain taxes resulting from the failure of the Merger to qualify as a tax-free
reorganization under Section 368(a) of the Code, and (6) any amounts paid in
respect of Dissenting Stock in excess of the Merger Consideration. The United
Indemnified Parties shall be entitled to indemnification for any Losses only
upon delivery of written notice of any claims to the Shareholder Representative.
United Indemnified Parties are entitled to payment for any Losses only to the
extent such Losses in the aggregate exceed $1,000,000. Furthermore, such right
to payment is limited to, and shall be payable only in the form of, an offset
against the Earn-Outs but only if such amount (1) has not already been paid to
the holders of LIPA Common Stock at the Effective Time, and (2) would not
previously have been paid to such holders if United were, at the time the claim
is asserted, in full compliance with the provisions of the Merger Agreement
relating to the payment of Contingent Payment Rights. The rights of the United
Indemnified Parties to indemnification will expire as to any claim that has not
been asserted prior to 5:00 p.m., Minneapolis time, on May 15, 1998; provided,
however, that if any such claim is based on a breach of representation or
warranty relating to any Community Health Entity, the right will expire as to
any claim that has not been asserted prior to 5:00 p.m., Minneapolis time, May
15, 1997. The

                                      49
<PAGE>
 
Shareholder Representative shall be entitled, on behalf of the Company's
shareholders, to contest and defend certain actions or proceedings brought by a
third party against a United Indemnified Party, subject to certain conditions.
United shall pay the reasonable fees and reimbursable expenses of any attorneys
and all other reasonable expenses of conducting such defense.

     United has agreed that, from and after the Effective Time, United shall,
subject to the limitations set forth below, indemnify and hold harmless the
former shareholders of LIPA and the Shareholder Representative (collectively,
the "Shareholder Indemnified Parties") from and against any Losses which any
Shareholder Indemnified Party may suffer, sustain or become subject to as a
result of (1) any representation or warranty by United in the Merger Agreement
relating to the validity of the United Common Stock received by such Shareholder
Indemnified Party in connection with the Merger, that it is not true and correct
as of the date made, (2) any breach by United or the Surviving Corporation of
any covenant or agreement contained in the Merger Agreement required to be
performed after the Effective Time, (3) certain claims by a person who held
shares of LIPA Common Stock prior to the Effective Time relating to a breach of
fiduciary duty or other improper action, and (4) certain claims for
indemnification by officers and directors of LIPA. The Shareholder Indemnified
Parties shall be entitled to indemnification for any Losses described above only
if a Shareholder Indemnified Party delivers to United written notice describing
such claim or claims prior to (1) 5:00 p.m., Minneapolis time, May 15, 1998, if
such claim is based on the untruth or incorrectness of a representation or
warranty of United or (2) two years after the Shareholder Indemnified Party
asserting the claim became aware of such claim, in all other cases.

     United has agreed that, from and after the Effective Time, United will (and
will cause the Surviving Corporation to) jointly and severally indemnify, defend
and hold harmless the present and former officers and directors of LIPA
(collectively, the "LIPA Indemnified Parties") against all losses, expenses
(including reasonable attorney's fees), claims, damages, liabilities, costs or
judgments or amounts that are paid in settlement with the written consent of
United arising out of actions or omissions occurring at or prior to the
Effective Time in the LIPA Indemnified Parties' respective capacities as
officers and/or directors of LIPA and/or any of the Community Health Entities
(except for claims relating to the particular LIPA Indemnified Party's purchase
of LIPA Common Stock from another shareholder of LIPA), and will also advance
expenses as incurred, all to the full extent permitted by the laws of Louisiana
or LIPA's Articles of Incorporation and Bylaws. See "COMPARISON OF SHAREHOLDER
RIGHTS--Indemnification." LIPA shall use reasonable efforts to obtain tail
coverage on the fiduciary liability, professional liability and directors and
officers liability policies currently covering LIPA or any of the LIPA
Indemnified Parties required to be indemnified by United at a commercially
reasonable cost, effective as of and following the Closing. In the event LIPA is
unable to obtain such tail coverage at a commercially reasonable cost, United
shall use reasonable efforts to provide similar coverage for those LIPA
Indemnified Parties that it is required to indemnify under policies then
maintained by United, provided that such coverage is available to United at a
commercially reasonable cost. Failure by LIPA or United to obtain such extended
tail coverage or to provide such coverage under United's policies shall not in
any way excuse United from its obligation to, and to cause the Surviving
Corporation to, indemnify, defend and hold harmless the LIPA Indemnified Parties
to the extent required by the Merger Agreement. If a claim is brought against
any LIPA Indemnified Party after the Effective Time, such LIPA Indemnified Party
may retain its own counsel, subject to prior reasonable approval by United. Upon
the occurrence of such a claim, United will pay the reasonable fees and expenses
of counsel selected by the LIPA Indemnified Party and will use reasonable
efforts to assist in the defense of such matter.

                     CERTAIN INFORMATION CONCERNING UNITED

GENERAL
    
     United is a national leader in offering health care coverage and related
services through a broad continuum of products and services. United served over
40 million covered lives at December 31, 1995. United's products and services
utilize a number of core capabilities, including medical information management,
health care delivery management, health benefit administration, risk assessment
and pricing, health benefit design and provider contracting and risk sharing.
With these capabilities, United is able to provide comprehensive managed care
services, such as HMO, insurance and self-funded health care coverage products,
as well as unbundled health care management and cost containment products such
as mental health and substance abuse services, utilization review services,
specialized provider networks and employee assistance programs. As part of its
ongoing acquisition program, United acquired MetraHealth on October 2, 1995.
MetraHealth is a managed health care coverage company and health insurer with
over ten million covered lives at the time of the acquisition. As a result of
the MetraHealth acquisition, United increased the geographic and product scope
of its health care coverage business and now has relationships with many of the
country's largest companies. On April 12, 1996, United acquired HealthWise, a
provider of a broad range of managed health care services to approximately
144,000 members through HMOs in Kentucky, Maryland, Tennessee and Arkansas. The
acquisition of HealthWise will, among other things, enhance United's position in
the Kentucky and Maryland markets.

     United is a Minnesota corporation, incorporated in January 1977. Unless the
context otherwise requires, the term "United" refers to United HealthCare
Corporation and its subsidiaries. United's executive offices are located at 300
Opus Center, 9900 Bren Road East, Minnetonka, Minnesota 55343; telephone (612)
936-1300.     

HEALTH PLANS, INSURANCE AND RELATED OPERATIONS
    
     Health Plans. As of December 31, 1995, United had a majority ownership
interest in health plans in 24 states and Puerto Rico. With respect to these
owned health plan operations, United assumes the risk for health care and
administrative costs in return for the premium revenue it receives. United's
owned health plans are usually licensed as HMOs or insurers and provide
comprehensive health care coverage for a fixed fee or premium that usually does
not vary with the extent of medical services received by the member. In
addition, these health plans enter into contractual arrangements with
independent providers of health care services to help manage medical and
hospital utilization, quality and costs. A few of the health plans employ health
care providers and directly deliver health care services to members. These plans
achieve cost-effective delivery of health care services by assuring appropriate
use of health care services, emphasizing preventive health services and
encouraging the reduction of unnecessary hospitalization and other medical
services. United also provides administrative and other management services to a
few health plans in which United has no ownership interest. With respect to
these managed health plan operations, United receives an administrative fee for
providing its services and generally assumes no responsibility for health care
costs.     

     Health Plan Point-of-Service Products. Point-of-service plans are one of
United's most popular and fastest growing health plan coverage options. Unlike
traditional closed-panel HMO products, which cover non-emergency services only
when rendered by contracted providers, the point-of-service plans also provide
coverage, usually at a lower level, for services received from non-contracting
providers. This out-of-network coverage is sometimes offered directly by the
health plan, but more often is provided by an insurance policy "wrapped around"
the health plan benefit contract. The insurance policy is usually sold by one of
United's insurance subsidiaries.

                                      54
<PAGE>
 
     Health Plan Self-Funded Products. United has developed HMO-like self-funded
products for employers who desire the cost containment aspects of an HMO product
and want to self-insure the health care cost risk. United uses the provider
networks it has developed in connection with its HMO products for these self-
funded products. Many of these self-funded products include a point-of-service
feature. The provider contracts for these products are with individual
physicians or groups of physicians as well as health care facilities and are
generally on a standardized fee-for-service basis. These self-funded products
offer employers and other sponsoring groups access to a provider network and the
administrative and utilization review services associated with an HMO product,
but the risks of health care utilization generally are borne by the sponsoring
group.
    
     Health Plan Medicare Products. Several of United's owned health plans
contract with the federal Health Care Financing Administration ("HCFA") to
provide coverage for Medicare-eligible individuals. Under these contracts the
plans receive a fixed payment each month from HCFA for each enrolled individual.
Several of United's health plans which do not currently have such a contract are
in the process of seeking one. Under these contracts, the health plans must
provide at least the benefits which would be covered under traditional Medicare
and typically provide a significantly higher level of coverage. The plans may,
but often do not, charge an additional premium to the members for the additional
benefits. The health plans generally use a subset of their commercial product
provider network as the provider network for the Medicare products. Any 
Medicare-eligible person in a plan's service area may enroll in the Medicare
product without underwriting or health screening.     

     Some of United's health plans may also offer these Medicare products to or
through employer groups as a method of providing retiree health care coverage.
In addition, certain health plans may market Medicare Select products which do
not substitute for traditional Medicare, but provide additional benefits for a
premium charged directly to the member.

     Health Plan Medicaid Products. Several of United's health plans offer
coverage to Medicaid-eligible individuals. These plans typically contract with a
state agency to provide such coverage and are paid a fixed monthly payment for
each enrolled individual. The level of benefits is generally set by contract and
few additional benefits are offered. Enrollment must usually be offered to all
eligible individuals, without underwriting or health screening. Generally, the
same provider network as for commercial products is utilized, but some providers
may refuse to participate in the Medicaid product and the network may otherwise
have a different number or set of providers.
    
     PPO and Indemnity Insurance and Self-Funded Products. Primarily through its
insurance and third-party administrator subsidiaries, United offers a variety of
health insurance and self-funded plan products and services, covering
approximately ten million persons. Many of the insurance and self-funded
products are marketed as point-of-service products or include a preferred
provider organization ("PPO") feature, under which a higher level of coverage is
available if certain providers are utilized. The insurance products are often
sold on an experience-rated basis, which means that the premiums may be adjusted
in the future based on actual past health care costs or that premiums may be
adjusted at the end of a specific time period (usually one year) with premium
returned to the customer or additional premium paid to United based on health
care costs in that time period. Much of the insurance business is sold to small
employers. This type of business has often been subject to sudden and
unpredictable changes in health care costs and generally has high administrative
and marketing expenses. This business is also usually sold for a fixed premium,
with no experience adjustments and is subject to extensive state regulation.
United's self-funded products are usually sold on an administrative fee basis
and in some cases United may agree to penalties or rewards related to
administrative service standards and/or health care costs.     
    
     Ancillary Insurance Products. Through its insurance subsidiaries, United
offers several health insurance products in conjunction with health plan
products. These products permit employers to replace multiple health care
policies and vendors with a single health care plan. These subsidiaries     

                                      55
<PAGE>

    
also offer reinsurance and other insured products on a selective basis to most
of United's health plans and to employers and other sponsoring groups offering
self-funded health care benefit plans. United's insurance subsidiaries are
licensed to sell group life, accidental death and dismemberment, short-term
disability and health insurance products in all 50 states, the District of
Columbia, Puerto Rico and the Virgin Islands. In connection with the MetraHealth
acquisition, United entered into an agreement with Metropolitan Life Insurance
Company ("MetLife") under which United offers MetLife's life, accidental death
and dismemberment and short-term disability products to United customers and
MetLife offers United's health care coverage products to MetLife customers. This
agreement with MetLife also contains certain mutual exclusivity and non-
competition provisions.     

     The following tables provide information with respect to the enrollment in
United's various health plan and insurance products. The enrollment numbers are
provided as of December 31, 1995 and January 31, 1996 since a number of the
contracts for United's health care coverage products commence, expire or renew,
as the case may be, as of January 1 of each year.

SPECIALTY MANAGED CARE SERVICES
    
     Through its experience in providing comprehensive health care management
products and in response to increasing market demand for greater choice and
flexibility in the design of health care coverage products and funding
arrangements, United has utilized its core capabilities to create and sell
specialized products to facilitate the efficient delivery of health care
services. These products are offered through United's specialty managed care
services business units and independently of United's owned and managed health
plans and insurance operations. United also makes these products available to or
in connection with the products of its owned and managed health plans and
insurance operations where feasible.     

     With respect to its specialty managed care services, United receives fees
for the provision of services, primarily administrative in nature, and generally
assumes no responsibility for health care costs except in the case of its
behavioral health products. In connection with those products, United assumes
some responsibility for health care costs for the provision of mental
health/substance abuse services and thus recognizes premium-like revenue and
medical services expense.

     United's specialty managed care products were available to a total of
approximately 40 million participant lives at December 31, 1995, many of whom
were not enrolled in one of United's owned health plans. One person may be
covered by more than one specialty managed care service and therefore may
account for more than one of these participant lives. United offers the
following specialty managed care services to HMOs, PPOs, insurers, providers,
Blue Cross/Blue Shield plans, third-party administrators, employers, labor
unions and/or government agencies.

     Care Management and Benefit Administration Services. United's care
management programs offer customers unbundled cost and utilization review and
case management services. These services include prior, concurrent and
retrospective review of hospital admissions and certain ambulatory services,
second opinion programs, case management, specialist referrals and discharge
planning. These services emphasize patient and provider education as a means of
assisting clients in managing their health care costs.

     United's Total Care Management programs offer those customers who may not
have geographic access to United's health plans an alternative to bundled
managed care services. These services include utilization management, medical
information and education, claims payment, provider networks, mental
health/substance abuse services and other related services. Use of these
services can provide health plan-like results to those clients who have members
outside health plan service areas.

     Transplant Network. United's transplant network services programs offer
clients access to a network of health care facilities for transplant-related
services and transplant case management services. United negotiates fixed,
competitive rates for high-cost, low-frequency health care services such as
organ and tissue transplants.
    
     Workers Compensation and Disability Management Services. United's workers
compensation and disability management services tailor United's broad managed
care resources into products and services intended to apply managed care
concepts, such as utilization review and use of specialized preferred provider
networks, to workers compensation and casualty insurance cases. These products
and services include hospitalization and outpatient surgery pre-certification
and case management, access to provider networks, specialized programs such as
carpal tunnel and back injury case management, and review of imaging (CAT scans
and MRI) services. United has recently sold one of its subsidiaries engaged in
this business.     

                                      57
<PAGE>
 
     Demand Management Programs. United's demand management programs help
consumers make informed choices about their health and well-being by focusing on
preventive care, self-care, smart lifestyle options, and consumer education.
United's OPTUM/(R)/ 24-hour nurseline and employee assistance programs provide
customers the opportunity to reduce the cost of medical care by early
identification of medical and human risks and the subsequent development of
problem-specific solutions that change behavior and reduce those risks. In
addition, these programs issue various publications to members as supplementary
tools for managing demand for services.

     Geriatric Care Management Services. United also develops and provides
products and services for cost control and the management of health care for the
elderly. LinkAge/(R)/ identifies for hospitals high-cost, high-risk patients
upon admission and provides the hospital with tools to perform focused case
management throughout the patient's hospital stay. United's EverCare/(R)/
program arranges for the provision of a broad spectrum of health care services
to institutionalized elderly individuals in nursing homes through contracts with
a physician-nurse practitioner team. EverCare/(R)/ is participating in a
demonstration project with HCFA to offer health care services to the
institutionalized elderly in nine separate locations throughout the country.

     Through its Government Operations division, United provides administrative
services in regard to certain government health care programs. Most of this
business is Medicare Part B claims processing. One of United's insurance
subsidiaries is the sole carrier for the states of Minnesota, Virginia,
Mississippi and Connecticut. That subsidiary also serves as the fiscal
intermediary for Medicare Part A in Connecticut, Michigan and New York, and
handles all Medicare durable medical equipment claims for the 10 states in
HCFA's northeast region.

     Behavioral Health Services. The specialty operations in United's behavioral
health services business unit include mental health and substance abuse-related
services. United's behavioral health subsidiaries provide specialized provider
networks and behavioral health care case management services to certain of
United's owned or managed health plans and to other customers. Such services are
provided by employed behavioral health care professionals and by a network of
contracted providers. Certain of these services are sold on a capitated basis.

     Third Party Administration Services. United provides third party
administrator ("TPA") services to employers who choose to utilize self-funding
to control health care costs and also desire customized health care plans and
administration. United's TPA services are available to employers of all sizes in
both single and multiple locations and include a fully integrated portfolio of
products.

     International Business. United has begun exploring opportunities to sell
its products and services in foreign countries and anticipates utilizing various
arrangements such as joint ventures, as well as direct contracting. United has
entered into a joint venture to create a health plan in the Republic of South
Africa and has entered into an agreement to provide certain managed care
consulting services in Germany.
    
     The Center for Health Care Policy and Evaluation. As the research and
performance evaluation arm of United, the Center for Health Care Policy and
Evaluation (the "Center") studies the operations and populations of enrolled
health care systems. The Center's research studies and analytical tools evaluate
cost and quality of health care delivery--illuminating common problems such as
uneven access to care, variations in treatment, patient non-compliance with
preventive care and other differences in the health care characteristics of the
studied population. United's health plans and specialty organizations across the
country use Center-developed tools and methods to monitor and assess health care
delivery to their members and clients. The Center also works on behalf of other
external organizations and clients to provide research services and analytic
software tools.     

                                      58
<PAGE>
     
     One of the Center's major software services (EPIS/TM/) is a specialized
medical management software system that provides clients with an integrated
picture of a health care system in many dimensions, replacing piecemeal reports
with a common reference point on cost, utilization, quality, access and
satisfaction.     
    
EXPANSION AND DIVESTITURE OF OPERATIONS

     United continually evaluates opportunities to expand its business and
considers whether to divest or cease offering the products of certain of its
businesses. These opportunities may include acquisitions or dispositions of a
specialty managed care services program or of insurance and health plan
operations. United also devotes significant attention to internal development of
new products and techniques for the containment of health care costs, the
measurement of the outcomes and efficiency of health care delivered and the
management of health care delivery systems.     
    
     United has engaged in an extensive acquisition program over the last few
years. The intensive acquisition program may affect United's ability to
integrate and manage its overall business effectively, which may increase costs,
affect membership, revenue and earnings growth and adversely affect United's
financial results. United's recent acquisition of MetraHealth poses significant
integration challenges, particularly since MetraHealth itself was the product of
a merger of businesses that were not yet fully integrated. Failure to integrate
MetraHealth successfully would likely materially adversely affect United's
financial results.     
    
     The acquisition of MetraHealth also may make United's revenues more
sensitive to fluctuations in overall health care cost trends, because the
proportion of the former MetraHealth revenues derived from indemnity insurance
business, which may have a lesser degree of health care cost control, is
relatively high, and because former MetraHealth revenues will constitute a
substantial portion of United's revenues.     
    
      On February 21, 1996, United executed an agreement to purchase the owner
of the remaining minority equity interest in its St. Louis, Missouri-based
health plans. On March 29, 1996, the Company acquired PHP, Inc., a North
Carolina based health plan to which United had previously provided
administrative services. On April 12, 1996, the Company merged with HealthWise
and thus acquired HealthWise's related health plan operations in Arkansas,
Tennessee, Maryland and Kentucky.     
    
     On March 1, 1996, United sold MetraHealth Care Plan of St. Louis, Inc., a
St. Louis, Missouri-based HMO acquired in October 1995 as part of the
MetraHealth acquisition and which had 33,600 enrollees at January 31, 1996. On
April 1, 1996, United sold its FOCUS Healthcare Management, Inc. subsidiary. On
April 4, 1996, United sold its EDI Services division to ActaMed Corporation, a
Georgia corporation in which United has a minority interest.     

GOVERNMENT REGULATION

     United's primary business, offering health care coverage and health care
management services, is heavily regulated at both the federal and state level.
United believes that it is in compliance in all material respects with the
various federal and state regulations applicable to its current operations. To
maintain such compliance, it may be necessary for United or a subsidiary to make
changes from time to time in its services, products, structure or marketing
methods.
    
     Government regulation of health care coverage products and services is a
changing area of law that varies from jurisdiction to jurisdiction. Changes in
applicable laws and regulations are continually being considered and the
interpretation of existing laws and rules may also change from time to time.
Regulatory agencies generally have broad discretion in promulgating regulations
and in interpreting and enforcing laws and rules. While United is unable to
predict what regulatory changes may occur or     

                                      59
<PAGE>

     
the impact on United of any particular change, United's operations and financial
results could be negatively affected by regulatory revisions. Certain proposed
changes in Medicare and Medicaid programs may increase the opportunities for
United to enroll persons under products developed for the Medicare and Medicaid
eligible populations, but other proposed changes also may limit the
reimbursement available to United and increase competition in those programs,
which could adversely affect United's financial results. The continued
consideration and enactment of "anti-managed care" laws and regulations, such as
"any willing provider" laws and limits on utilization management, by federal and
state bodies may make it more difficult for United to control medical costs and
may adversely affect financial results.     

     A number of jurisdictions have enacted small group insurance and rating
reforms which generally limit the ability of insurer and health plans to use
risk selection as a method of controlling costs for small group business. These
laws may generally limit or eliminate use of preexisting conditions exclusions,
experience rating and industry class rating and may limit the amount of rate
increases from year to year. Under these laws, cost control through provider
contracting and managing care may become more important and United currently
believes its experience in these areas will allow it to compete effectively.

     In addition to changes in applicable laws and rules, United is potentially
subject to governmental investigations and enforcement actions. These include
possible government actions relating to the federal Employee Retirement Income
Security Act ("ERISA"), which regulates insured and self-insured health coverage
plans offered by employers and United's services to such plans and employers,
the Federal Employees Health Benefit Plan ("FEHBP"), federal and state fraud and
abuse laws and laws relating to utilization management and the delivery of
health care. Any such government action could result in assessment of damages,
civil or criminal fines or penalties, or other sanctions, including exclusion
from participation in government programs. Although United is currently involved
in various government audits, such as under the FEHBP or relating to services
for ERISA plans, United does not believe the results of such current audits
will, individually or in the aggregate, have a material adverse effect on
United's financial results.

     HMOs. All of the states in which United's health plans offer HMO products
have enacted statutes regulating the activities of those health plans. Most
states require periodic financial reports from HMOs licensed to operate in their
states and impose minimum capital or reserve requirements. Certain of United's
subsidiaries are required to retain for their own use cash generated from their
operations. In addition, certain of United's subsidiaries are required by state
regulatory agencies to maintain restricted cash reserves represented by 
interest-bearing instruments which are held by trustees or state regulatory
agencies to ensure that adequate financial reserves are maintained. Some state
regulations enable agencies to review all contracts entered into by HMOs,
including management contracts, for reasonableness of fees charged and other
provisions.

     United's health plans which have Medicare risk contracts are subject to
regulation by HCFA. HCFA has the right to audit health plans operating under
Medicare risk contracts to determine each health plan's compliance with HCFA's
contracts and regulations and the quality of care being rendered to the health
plan's members. To enter into Medicare risk contracts, a health plan must either
be federally qualified or be considered a Competitive Medical Plan under HCFA's
requirements. Health plans which offer a Medicare risk product also must comply
with requirements established by peer review organizations ("PROs"), which are
organizations under contract with HCFA to monitor the quality of health care
received by Medicare beneficiaries. PRO requirements relate to quality assurance
and utilization review procedures. United's health plans which have Medicare
cost contracts are subject to similar regulatory requirements. In addition,
these health plans are required to file certain cost reimbursement reports with
HCFA which are subject to audit and revision.

                                      60
<PAGE>
 
     United's health plans which have Medicaid contracts are subject to both
federal and state regulation regarding services to be provided to Medicaid
enrollees, payment for those services and other aspects of the Medicaid program.
Both Medicare and Medicaid have in force or have proposed regulations relating
to fraud and abuse, physician incentive plans and provider referrals which may
affect United's operations.

     Many of United's health plans have contracts with FEHBP. These contracts
are subject to extensive regulation, including complex rules relating to the
premiums charged. FEHBP has the authority to retroactively audit the rates
charged and frequently seeks premium refunds and other sanctions against health
plans participating in the program. United's health plans which have contracted
with FEHBP are subject to such audits and may be requested to make such refunds.

     Insurance Regulation. United's insurance subsidiaries are subject to
regulation by the Department of Insurance in each state in which the entity is
licensed. Regulatory authorities exercise extensive supervisory power over
insurance companies in regard to licensing; the amount of reserves which must be
maintained; the approval of forms of insurance policies used; the nature of, and
limitation on, an insurance company's investments; periodic examination of the
operations of insurance companies; the form and content of annual statements and
other reports required to be filed on the financial condition of insurance
companies; and the establishment of capital requirements for insurance
companies. United's insurance company subsidiaries are required to file periodic
statutory financial statements in each jurisdiction in which they are licensed.
Additionally, such companies are periodically examined by the insurance
departments of the jurisdiction in which they are licensed to do business.

     Insurance Holding Company Regulations. Certain of United's health plans and
each of United's insurance subsidiaries are subject to regulation under state
insurance holding company regulations. Such insurance holding company laws and
regulations generally require registration with the state Department of
Insurance and the filing of certain reports describing capital structure,
ownership, financial condition, certain intercompany transactions and general
business operations. Various notice and reporting requirements generally apply
to transactions between companies within an insurance holding company system,
depending on the size and nature of the transactions. Certain state insurance
holding company laws and regulations require prior regulatory approval or, in
certain circumstances, prior notice of, certain material intercompany transfers
of assets as well as certain transactions between the regulated companies, their
parent holding companies and affiliates, and acquisitions.

     TPAs. Certain subsidiaries of United are also licensed as third-party
administrators ("TPAs") in states where such licensing is required for their
activities. TPA regulations, although differing greatly from state to state,
generally contain certain required administrative procedures, periodic reporting
obligations and minimum financial requirements.

      PPOs. Certain of United's subsidiaries' operations may be subject to PPO
regulation in a particular state. PPO regulations generally contain certain
network, contracting, financial and reporting requirements which vary from state
to state.

     Utilization Review Regulations. A number of states have enacted laws and/or
adopted regulations governing the provision of utilization review activities and
these laws may apply to certain of United's operations. Generally, these laws
and regulations require compliance with specific standards for the delivery of
services, confidentiality, staffing, and policies and procedures of private
review entities, including the credentials required of personnel.
    
     MCOs. In recent years a number of states have enacted laws enabling self-
insured employers and/or insurance carriers to apply medical management and
other managed care techniques to the     

                                      61
<PAGE>

     
medical benefit portion of workers compensation if such managed care is
performed by a state certified managed care organization ("MCO"). United, by
itself or with its HMOs, has generally sought MCO certification in the states
where it is available and where it markets managed care workers compensation
products. MCO laws differ significantly from state to state, but generally
address network and utilization review activities.     
    
     ERISA. The provision of goods and services to or through certain types of
employee health benefit plans is subject to ERISA. ERISA is a complex set of
laws and regulations that is subject to periodic interpretation by the United
States Department of Labor. ERISA places controls on how United's business units
may do business with employers covered by ERISA, particularly employers that
maintain self-funded plans. The Department of Labor is engaged in an ongoing
ERISA enforcement program which may result in additional constraints on how
ERISA-governed benefit plans conduct their activities. There recently have been
legislative attempts to limit ERISA's preemptive effect on state laws. If such
limitations were to be enacted, they might increase United's liability exposure
under state law-based suits relating to employee health benefits offered by
United's health plans and specialty businesses and may permit greater state
regulation of other aspects of those businesses' operations.     

MANAGEMENT INFORMATION SYSTEMS

     United's health plans, insurance, self-funded and specialty managed care
products use computer-based management information systems for various purposes,
including claims processing, billing, utilization management, underwriting,
marketing and sales tracking, general accounting, medical cost trending, managed
care reporting and financial planning. These systems also support member, group
and provider service functions, including on-line access to membership
verification, claims and referral status and information regarding hospital
admissions and lengths of stay. In addition, these systems support extensive
analysis of cost and outcome data.
    
     United continually evaluates, upgrades and enhances the computer
information systems which support its operations. System development efforts
relating to increased efficiency, capacity and flexibility are ongoing. United's
computer processing capabilities support multiple product delivery systems with
attendant tracking and processing for such systems, an integrated database of
information for increased reporting and research capabilities, and use automated
entry and edit capabilities to speed the capture and processing of information.
Over the past several years, United has upgraded its mainframe computers,
enhanced its existing software functionality and migrated to various software
database environments. This approach allows United to preserve its investment in
existing systems while, at the same time, enabling it to exploit new
technologies that help improve either the cost effectiveness of the services
provided, or allow for the introduction of new product capabilities. Following
the MetraHealth acquisition, United has begun an extensive review of its
information systems, including integration of multiple systems. United has also
agreed to outsource operation of a substantial portion of its computer
operations centers to a third party. Simplification and integration of the many
different systems now servicing United's business is an important component of
controlling administrative expenses and effectively managing United's
operations. To the extent that these integration efforts are not successful,
United's financial results may be adversely affected.     

MARKETING

     United's marketing strategy and implementation for its health plan,
insurance, self-funded and specialty and managed care products are defined and
coordinated by United's corporate marketing staff. Primary marketing
responsibility for each of United's health plans and specialty managed care
products resides with a marketing director and a direct sales force. In
addition, United's health plan, insurance, self-funded and specialty managed
care products are sold through independent insurance agents and brokers.
Marketing efforts are supported by ongoing market research that identifies and

                                      62
<PAGE>
 
grades prospective customers and establishes specific enrollment goals by
territory and employer. Marketing efforts are also supported by public relations
efforts and advertising programs that may employ television, radio, newspapers,
billboards, direct mail and telemarketing.

COMPETITION
    
     The managed health care industry evolved primarily as a result of health
care buyers' concerns regarding rising health care costs. The industry's goal is
to infuse greater cost effectiveness and accountability into the health care
system through the development of managed care products, including health plans,
PPOs, and specialized services such as mental health or pharmacy benefit
programs, while increasing the accessibility and quality of health care
services. The industry in which United operates is highly competitive and
significant consolidation has occurred within the industry, creating stronger
competitors. At the same time, there are a number of new entrants to the
industry, which may also increase competitive pressures. The current competitive
markets in certain areas may limit United's ability to price its products at
levels United believes appropriate. These competitive factors could adversely
affect United's financial results.     

     As HMO and PPO penetration of the health care market and the effects of
health care reforms increase nationwide, United expects that obtaining new
contracts for its HMO and PPO products with large employer and government groups
may increasingly become more difficult and that competition for smaller employer
groups will intensify. In addition, employers may increasingly choose to self-
insure the health care risk while seeking benefit administration and utilization
review services from third parties to assist them in controlling and reporting
health care costs.

     United's health plan, insurance, self-funded and specialty managed care
coverage products compete for group and individual membership with other health
insurance plans, Blue Cross/Blue Shield plans, other health plans, HMOs, PPOs,
third party administrators and health care management companies, and employers
or groups which elect to self-insure. United also faces competition from
hospitals, health care facilities and other health care providers who have
combined and formed their own networks to contract directly with employer groups
and other prospective customers for the delivery of health care services.
United's ability to increase the number of persons covered by its products or
services or to increase its premiums and fees can be affected by the number and
strength of United's competitors in any particular area. United believes that
the principal competitive factors affecting United and its products include
price, the level and quality of products and service, provider network
capabilities, market share, the offering of innovative products, product
distribution systems, financial strength, and marketplace reputation.
    
     Further, United currently believes that factors that generally help it in
regard to competitors are the breadth of its product line, its geographic scope
and diversity, the strength of its underwriting and pricing practices and staff,
its significant market position in certain geographic areas, the strength of its
distribution network, its financial strength, its generally large provider
networks, which provide more member choice, its point-of-service products and
experience and its generally favorable marketplace reputation. In a number of
markets United may be at a disadvantage in regard to competitors with larger
market shares, broader networks, narrower networks (which may allow greater cost
control and lower prices) or a more-established marketplace name and 
reputation.

                      CERTAIN INFORMATION CONCERNING LIPA

THE BUSINESS OF LIPA

     LIPA is a physician owned holding company, which was formed in October 1985
by approximately 400 medical physicians practicing in Baton Rouge, Louisiana and
the surrounding area. LIPA was formed to act as a holding company of an HMO
organized in 1986 as Southeast Health Plan of Louisiana ("Southeast"). Southeast
was managed under a contract with a regional health care management company.

     During 1987, Southeast experienced rapid growth in membership but sustained
losses from operations. In 1987, the management contract was terminated due to
unprofitable operating results. Thereafter, the Board of Directors of LIPA
assumed management responsibility of Southeast, but changed the HMO's name from
Southeast to Community Health Network of Louisiana, Inc. ("CHN," as previously
defined).

     Due to the losses sustained in 1987, CHN needed capital to continue its
operations and to attract experienced personnel. To meet this need, the Board of
Directors of LIPA entered into negotiations with investors who were also
investors in Complete (the "Complete Investors"). As a result of these
negotiations, LIPA and the Complete Investors formed LHMC. The Complete
Investors acquired 51% of LHMC and LIPA acquired 49%. The Complete Investors
also acquired 51% of LHP, the corporation that is the general partner and 1%
owner of LHMC. At the same time, the Complete Investors acquired 49% of CHN from
LIPA. LHMC then entered into a management contract to manage CHN.
    
     CHN has approximately 108,000 members enrolled in its commercial HMO
products and also provided services to approximately 6,000 HMOs and PPOs. CHN
has a contracted network of health care providers that included approximately
2,452 physicians as of April 1, 1996. Pursuant to its commercial HMO plans, CHN
receives monthly premium payments based on rates fixed by contract with
employers and other groups and, in contrast to self-funded HMO and PPO products,
assumes the risk that the premiums will cover the costs of the health care
services provided by CHN's network of health care providers. CHN contracts with
physicians, hospitals and other health care providers to provide services to
members and to negotiate provider contracts that specify rates which are
discounted from billed charges and require utilization management and other cost
control measures. Under CHN's risk-sharing model, primary and specialty care
physicians also assume part of the utilization risk through a withholding
arrangement on their contractual payments. Certain of CHN's HMO plans also
include a "point of service" option that permits members to receive certain
health care services from providers that are not included in CHN's provider
network, or to see a specialist without the prior referral of a designated
primary care physician at an additional out-of-pocket cost to the member that
includes a deductible and higher co-payment percentage obligations.     

     Under CHN's self-funded HMO and PPO plans, the employer or group assumes
the risk of its employees' health care costs, and CHN receives an administrative
fee for designing benefit packages, claims processing and administration,
utilization management, generation of management reports and other related
matters. Like its commercial HMO products, CHN's self-funded products utilize
CHN's network of health care providers and thereby benefit from negotiated
rates, utilization management and other cost control measures negotiated by CHN
with its providers. CHN's PPO plans, all of which are self-funded plans, are
similar to its HMO plans in providing health care delivery at lower costs than
traditional health insurance through a provider network under contracts which
specify negotiated rates. Members of CHN's PPO, however, may choose physicians
from the PPO network to perform required services without the prior approval of
a designated primary care physician. PPO members typically are subject to
deductible requirements and higher premiums and co-payment obligations than HMO
members. PPO members also have the option to receive health care services

                                       64
<PAGE>

     
from providers that are not a part of CHN's network, typically at additional 
out-of-pocket costs to the member.

     Comparison of the Year Ended December 31, 1995 and 1994

     Premiums.  LIPA's premiums increased by $54.4 million or 66.3% to $136.5
million for the year ended December 31, 1995 from $82.1 million for 1994.  This
increase resulted primarily from an increase in membership of 43.6% and an
increase in the average premium yield of $21 per member per month ("PMPM"), or
16.0%, in average PMPM premiums.  This large increase in the PMPM yield is due
primarily to the significant growth in LIPA's higher-yield Medicare risk
product.

     Investment and Other Revenues.  LIPA's investment and other revenues
increased slightly to $382,000 for the year ended December 31, 1995 compared to
the corresponding period in 1994.  LIPA's investment revenue consists primarily
of interest earned on overnight repurchase agreements.  The increase is a result
of higher average daily investment balances in 1995 compared to 1994 and higher
interest rates.

     Medical Services Expenses.  Medical services expenses increased $47.3
million or 68.3% to $116.6 million for the year ended December 31, 1995 from
$69.3 million for the year ended December 31, 1994. This increase resulted
primarily from the 43.6% increase in membership and an increase of $16, or
14.8%, in average PMPM medical services costs. This increase is due to the
significant growth in the more costly medicare risk product.

     Medical Loss Ratio.  LIPA's medical loss ratio, which is medical services
costs as a percent of premiums, increased from 84.4% for the year ended December
31, 1994 to 85.4% for the year ended     

                                       -66-
<PAGE>

    
December 31, 1995. This increase occurred in large part because the significant
growth in the higher-yield and higher cost Medicare risk product.

     Management Fee Expenses.  Pursuant to the terms of an administrative
management contract, CHN, one of LIPA's subsidiaries, pays LHMC 15.0% of CHN's
premium revenues for management services.

     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses increased $1.9 million, or 262%, to $2.6 million for the
year ended December 31, 1995 compared to the corresponding period in 1994.  This
increase is primarily the result of LIPA increasing the use of outside brokers
in 1995 to sell LIPA's products and increase membership.  Broker commissions
increased 360% in the year ended December 31, 1995 compared to the corresponding
period in 1994.

     Equity in Earnings of Unconsolidated Affiliates.  Equity in earnings of
unconsolidated affiliates represents LIPA's equity interest in the earnings of
LHMC and LHP.  LIPA accounts for these investments under the equity method of
accounting.  LIPA's equity in earnings of unconsolidated affiliates increased
$2.2 million, or 164%, to $3.6 million for the year ended December 31, 1995
compared to the corresponding period in 1994.  This increase is the result of
increased net income at LHMC and LHP, as  LIPA's ownership percentages in LHMC
and LHP did not change in 1995 or 1994.     

     Comparison of the Years Ended December 31, 1994 and December 31, 1993
    
     Premiums.  LIPA's premiums increased by $16.6 million, or 25.2%, to $82.2
million for the year ended December 31, 1994 from $65.6 million for the year
ended December 31, 1993.  This increase resulted primarily from an increase in
membership of 14% and an increase in the average premium yield of $12 PMPM, or
10%, for the year ended December 31, 1994 compared to the corresponding period
in 1993.     

     Investment and Other Revenue.  LIPA's investment and other revenues
decreased 43.5% to $373,000 for the year ended December 31, 1994 compared to the
corresponding period in 1993.  LIPA's investment revenue consists primarily of
interest earned on overnight repurchase agreements for LIPA's cash balances.
Revenues on such agreements decreased because LIPA's average daily cash balances
were lower.

     Medical Services Expenses.  Medical services expenses increased 25.5% for
the year ended December 31, 1994 to $69.3 million from $55.2 million for the
year ended December 31, 1993.  This increase resulted primarily from the 17%
increase in membership and an increase of $10 PMPM, or 10%, in average PMPM
medical services costs.

     Medical Loss Ratio.  LIPA's medical loss ratio, which is medical services
costs as a percent of premiums, remained relatively flat at 84.4% and 84.2% for
the years ended December 31, 1994 and 1993, respectively.

     Management Fee Expenses.  Management fees remained the same at 15% of CHN's
premium revenues for the years ended December 31, 1994 and 1993.

     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses increased $234,000, or 49.0%, to $712,000 for the year
ended December 31, 1994 compared to the corresponding period in 1993.  This
increase is primarily the result of LIPA using outside brokers in 1994 to sell
LIPA's products and increase enrollment.  Prior to 1994, internal marketing
personnel performed these functions for LIPA.

                                      -67-
<PAGE>
    
     Equity in Earnings of Unconsolidated Affiliates.  LIPA's equity in earnings
of unconsolidated affiliates increased $282,000, or 26.1%, to $1.4 million for
the year ended December 31, 1994 from $1.1 million for the year ended December
31, 1993. This increase is the result of increased net income at LHMC of
$645,000 primarily attributable to higher management contract fee revenue.
LIPA's ownership percentages in LHMC did not change in 1994 or 1993.
    
     Liquidity and Capital Resources     
    
     LIPA's principal source of liquidity and working capital has historically
been cash flows from operations.  At December 31, 1995, cash and cash
equivalents totaled approximately $262,000 and had a working capital deficit of
approximately $351,000.  Net cash used in operating activities for the year
ended December 31, 1995 was $7.0 million compared to cash provided by operations
of $520,000 in the corresponding period in 1994.

     Cash used in operating activities for the year ended December 31, 1995
resulted primarily from (1) an excess of $1.8 million in earnings of
unconsolidated affiliates over net income, and (2) an increase in receivables of
$14.5 million resulting from a significant increase in membership in 1995 (3) an
increase in prepaid expenses and other of $1.2 million, offset by (4) an
increase in unearned premiums of $5.4 million due to timing differences in the
receipt of premium remittances and (5) an increase in medical services payable
of 5.1 million as a result of timing differences in claims payments.

     No material investing or financing activities occurred during the years
ended December 31, 1995 or 1994.     

     LIPA believes that its existing cash and cash equivalents and its cash
flows from operations will be adequate to fund its existing operations.  There
currently are no other material definitive commitments for future use of LIPA's
available resources.
    
     In January 1996, LIPA and United announced that they had entered into a
definitive merger agreement (the "Merger Agreement") whereby LIPA would become
an indirect wholly owned subsidiary of United.  Under the terms of the Merger
Agreement, and as of the record date for the meeting of LIPA Shareholders to be
held to approve the merger, each outstanding share of LIPA common stock will be
converted into the right to receive a pro rata allotment of an aggregate number
of shares of United Common Stock, subject to adjustment for the average per
share closing price of United Common Stock as reported on the NYSE, leading up
to the closing date of the merger.  Consummation of the merger is subject to
various conditions, including among other things, the approval by LIPA
shareholders of the merger pursuant to the Merger Agreement, receipt by LIPA and
United of an opinion of counsel as to the treatment of the merger as tax-free
reorganization for federal income tax purposes, and other customary closing
conditions.  The transaction is anticipated to close in the second quarter of
1996.

                       COMPARISON OF SHAREHOLDER RIGHTS

     The rights of the shareholders of LIPA are governed by the LBCL, the
Articles of Incorporation, as amended, of LIPA (the "LIPA Articles"), and the
Bylaws of LIPA (the "LIPA Bylaws").  The rights of the shareholders of United
are governed by the Minnesota Business Corporation Act (the "MBCA"), the
Restated Articles of Incorporation of United, as amended (the "United
Articles"), and the Amended and Restated Bylaws of United (the "United Bylaws").
The following is a summary of certain material differences between the rights of
shareholders of LIPA and the rights of shareholders of United, as contained in
provisions of the LBCL and the MBCA, the LIPA Articles and the LIPA Bylaws, and
the United Articles and the United Bylaws.

     The following does not purport to be a complete statement of the rights of
LIPA's shareholders under applicable Louisiana law, and the LIPA Articles and
the LIPA Bylaws as compared with the rights of United shareholders under
applicable Minnesota law, and the United Articles and the United Bylaws.  The
identification of certain specific differences is not meant to indicate that
other equally or more significant differences do not exist.

NUMBER OF DIRECTORS

     The LBCL provides that the board of directors of a Louisiana corporation
having more than two shareholders shall consist of three or more directors.  The
LIPA Articles and the LIPA Bylaws provide that the board shall consist of seven
to twenty-seven directors, all of whom must be LIPA shareholders.   The terms of
directors are staggered, with approximately one-half of the directors elected
each year for 2-year terms.  Directors may be removed at any time, with or
without cause, by a majority vote of the shareholders at a special meeting
called for that purpose.

     The MBCA provides that the board of directors of a Minnesota corporation
shall consist of one or more directors as fixed by the articles of incorporation
or bylaws.  The United Bylaws provide that the board shall consist of one or
more directors, which number may be increased or decreased from time to time by
resolution of a majority of the board (determined as if all vacancies are
filled) or at least two-thirds of the capital stock entitled to vote (voting as
one class).  Under the United Articles and United Bylaws, the directors are
divided into three classes which are to be as nearly equal as possible.
Directors in each class serve for three years, and elections are staggered such
that one class is elected each year.

     The United Bylaws further provide that a candidate for director must be
nominated by or at the direction of the board or by a shareholder.  If nominated
by a shareholder, a notice containing information about the candidate, the
shareholder nominating such candidate, and such other information as would be
required by federal securities regulations if proxies were to be solicited with
respect to such nomination, must be submitted to United not less than 60 days
prior to the date of the annual meeting.

ACTION OF DIRECTORS

       The LBCL provides that the act of a majority of directors present at a
meeting at which a quorum is present shall be the act of the board of directors.
The LIPA Bylaws require that a vote of two-thirds of the directors is required
to authorize, under certain circumstances, the appointment of non-shareholders
to the board of directors of subsidiaries of LIPA.

     Under the United Bylaws, the act of a majority of directors present at a
meeting at which a quorum is present is generally required to approve corporate
actions.  A vote of more than two-thirds of the directors in office is required,
however, to approve, with or without cause, the removal of any or all of the
directors.

VOTE ON MERGER, CONSOLIDATION OR SALE OF SUBSTANTIALLY ALL ASSETS

     The LBCL requires the affirmative vote of at least two-thirds of the voting
power present, or by such larger or smaller vote, but not less than a majority,
of the voting power present or of the total voting power as the articles of
incorporation may prescribe to effect (1) any merger or consolidation with or
into any other corporation, or (2) any sale or lease of any substantial part of
the assets of the corporation if the corporation is not insolvent.

     Section 133 of the LBCL places restrictions on "business combinations" (as
defined in Section 132(4) of the LBCL, generally including mergers,
consolidations, share exchanges, sales and leases of assets, issuances of
securities, and similar transactions) by Louisiana corporations with an
"interested stockholder" (as defined in Section 132(9) of the LBCL, generally as
the beneficial owner of 10% or more of the voting power of the then outstanding
voting stock).  Section 133 of the LBCL generally applies to business
combinations of Louisiana corporations having greater than 100 beneficial owners
of its stock or which did not have an interested stockholder on January 1, 1985,
unless the articles of incorporation expressly provide otherwise.  Section 133
of the LBCL generally does not apply, provided the stockholders receive in the
business combination substantially similar consideration for their shares of
stock in the corporation in terms of price and method of payment, as determined
in accordance with Section 134B of the LBCL, as the interested stockholder
received for its shares of stock in the corporation acquired by such interested
stockholder within two years of such business combination.

     Since LIPA has not specifically elected to avoid the application of Section
133 of the LBCL, Section 133 of the LBCL generally would prohibit a business
combination by LIPA with an interested stockholder, unless the business
combination is recommended by LIPA's board of directors and approved by the
affirmative vote of at least each of the following:  (1) 80% of the votes
entitled to be cast by outstanding shares of LIPA voting stock voting together
as a single voting group and (2) two-thirds of the votes entitled to be cast by
holders of voting stock, other than voting stock held by the interested
stockholder who is a party to the business combination with LIPA, voting
together as a single voting group.  Since United is not an "interested
stockholder" with respect to LIPA, Section 133 of the LBCL does not apply to the
Merger.

     Under Section 135 of the LBCL and the sections that follow it, any person
who acquires more than 20% of the voting power of a corporation such as LIPA may
not vote all or a portion of such shares unless the stockholders other than the
acquiring person have, at a duly called stockholders meeting, voted to permit
the acquiring person to exercise voting rights.

     The MBCA provides that a resolution containing a plan of merger or exchange
must be approved by the affirmative vote of a majority of the directors present
at a meeting, and submitted to the shareholders and approved by the affirmative
vote of the holders of a majority of the voting power of all shares entitled to
vote.  The MBCA requires that any class of shares of a Minnesota corporation
must approve the plan if it contains a provision which, if contained in a
proposed amendment to the corporation's articles of incorporation, would entitle
such class to vote as a class.  The United Articles require the affirmative vote
of not less than two-thirds of the outstanding shares entitled to vote generally
in the election of directors for approval of certain mergers, consolidations or
other combinations with affiliated entities.

     Although the MBCA contains a provision which restricts certain business
combination transactions with an interested shareholder for four years after
such shareholder has acquired 10% of the voting power of a publicly traded
corporation having 50 or more shareholders, United has elected, pursuant to its
Bylaws, not to be subject to the business combination rules of the MBCA.
Instead, the United Articles set forth certain other business combination
requirements.  Under the United Articles, if a business combination (including a
merger, disposition of substantial assets, issuance of securities and 
    
                                       -70-
<PAGE>

other similar transactions) occurs with a person who, together with its
affiliates, owns 20% or more of the outstanding capital stock of United (a
"Related Person"), then the combination must be approved by two-thirds of the
outstanding capital stock entitled to vote for directors. However, the
combination may occur without such a vote if, among other exceptions, (1) those
directors who were directors of United before the acquiring party became a
Related Person approve the combination by a two thirds vote, or those directors
approved the combination before the party became a Related Person or (2) if the
business combination is a merger or consolidation, the board of directors
determines that the cash or fair market value of all consideration to be
received by shareholders is at least equal to the highest per share price paid
by the Related Person in acquiring any of United's stock.

SHAREHOLDER PROPOSALS

     Neither the LIPA Articles nor the LIPA Bylaws contain a provision requiring
that a shareholder provide advance notice of any proposal to be submitted by
such shareholder at any meeting of LIPA shareholders.

     The United Bylaws require that a shareholder provide notice of any proposal
to be submitted at any annual meeting of shareholders to the Secretary of United
not less than 60 nor more than 90 days prior to the date of the meeting (subject
to a shorter time period if notice or public disclosure of the meeting occurs
less than 70 days prior to the meeting).

SPECIAL MEETINGS OF SHAREHOLDERS

     The LIPA Bylaws provide that special meetings of shareholders may be called
at any time by the President or by a majority of the directors.  The President
is required to call a special meeting of shareholders upon written request by
the holders of not less than one-tenth of all of the shares entitled to vote at
the meeting.  The LCBL provides that the date of a special meeting called at the
request of shareholders shall be fixed not less than 15 nor more than 60 days
after receipt of the request.  If the date of the meeting is not so fixed, or if
notice of the meeting is not given, then the shareholders making the request may
do so.

     The MBCA and the United Bylaws provide that the Chief Executive Officer,
the Chairman of the Board, the Chief Financial Officer, any two directors, or a
shareholder or shareholders holding 10% or more of shares entitled to vote at
such meeting may call a special meeting.  However, if the meeting involves a
business combination, including an action to affect the composition of the Board
of Directors, then at least 25% of the shares entitled to vote at such meeting
are required to call the meeting.  If the meeting is demanded by shareholders,
the meeting, on notice, must occur between 30 and 90 days after receipt of the
demand.

SHAREHOLDER ACTION BY WRITTEN CONSENT

     The LBCL provides that action required or permitted to be taken at a
meeting of shareholders may be taken without a meeting by unanimous consent of
all shareholders entitled to vote thereon.

     The MBCA provides that an action required or permitted to be taken at a
meeting of the shareholders may be taken without a meeting by written action
signed by all of the shareholders entitled to vote on that action.

AMENDMENT OF ARTICLES OF INCORPORATION

     The LIPA Articles provide that they may be amended by an affirmative vote
of at least a majority of the shareholders at any regular or special meeting of
shareholders, provided that the notice of such meeting includes the text of the
proposed amendments.
      
                                       -71-
<PAGE>

     The MBCA provides that an amendment to a corporation's articles must be by
resolution approved by the affirmative vote of a majority of the directors
present, or proposed by a shareholder or shareholders holding 3% or more of the
voting shares entitled to vote thereon.  Under the MBCA, such an amendment must
be approved by the affirmative vote of a majority of the shareholders entitled
to vote thereon, except that the articles may provide for a specified proportion
or number larger than a majority.  The United Articles provide that the
affirmative vote of the holders of two-thirds of the outstanding United Common
Stock is required in order to amend provisions of the United Articles concerning
the election and removal of directors, and that the affirmative vote of the
holders of two-thirds of the outstanding shares of capital stock entitled to
vote generally in the election of directors is required in order to amend
provisions concerning certain mergers, consolidations and other business
combinations and reorganizations.

AMENDMENT OF BYLAWS

     The LIPA Bylaws provide that they may be amended by affirmative vote of at
least a majority of the shareholders, at a regular or special meeting called for
the purpose, by written consent of a majority of the shareholders, or by
affirmative vote of at least a majority of the board of directors at a regular
or special meeting of the board called for that purpose.  However, no change of
the LIPA Bylaws governing the time or place for the election of directors shall
be made within 60 days preceding the date on which such election is to be held,
and notice of any change in such LIPA Bylaws shall be delivered to each
shareholder at least 20 days before such election is held.

     The MBCA and the United Bylaws provide that the power to adopt, amend or
repeal the bylaws shall be vested in the board (subject to certain notice
requirements set forth in the United Bylaws), except that the board shall not
adopt, amend, or repeal a bylaw fixing a quorum for a meeting of shareholders,
prescribing procedures for removing directors or filling vacancies in the board,
or fixing the number of directors or their classifications, qualifications, or
terms of office, but may adopt or amend a bylaw to increase the number of
directors.  Notwithstanding the above, under the MBCA a shareholder or
shareholders holding 3% or more of the voting shares entitled to vote may
propose a resolution to amend or repeal bylaws adopted, amended or repealed by
the board, in which event such resolution must be approved pursuant to the
procedures for amending the articles of incorporation.

LIABILITY OF OFFICERS AND DIRECTORS

     Neither the LIPA Articles nor the LIPA Bylaws contains a provision
exculpating officers and directors from liability to LIPA.

     The United Articles provides that a director shall not be personally liable
to United or its shareholders for monetary liability relating to breach of
fiduciary duty, unless the liability relates to a breach of the duty of loyalty,
acts or omissions involving a lack of good faith or an intentional or knowing
violation of law, liability for illegal distributions and unlawful sales of
United securities, transactions where the director gained an improper personal
benefit, or acts or omissions occurring prior to the date on which the liability
limitation provision was added to the United Articles.  The United Articles
provide that any amendment to the MBCA that authorizes further elimination or
limitation of director liability shall result in the further elimination or
limitation of liability of directors of United to the fullest extent permitted
by the MBCA, as so amended.

INDEMNIFICATION OF OFFICERS AND DIRECTORS

     The LIPA Articles provide that LIPA is permitted to indemnify its officers
and directors for their expenses and liabilities in actions, other than actions
brought by or on behalf of LIPA, brought against them by reason of the fact that
they are or were officers or directors of LIPA.  Such 

                                       -72-
<PAGE>

indemnification could be made only if the indemnitee used the prevailing party
or if it were determined in the specific case that the proposed indemnitee acted
in good faith and in a manner such person reasonably believed to be in or not
opposed to the best interests of LIPA and, with respect to any criminal
proceedings, if such person had no reasonable cause to believe that the conduct
was unlawful. In actions brought by or on behalf of LIPA, such indemnification
probably would be limited to reasonable expenses (including attorneys' fees) and
would apply if it were determined in the specific case that the proposed
indemnitee acted in good faith and in a manner such person reasonably believed
to be in or not opposed to the best interests of LIPA, except that no
indemnification may be made with respect to any matter as to which such person
is adjudged liable to LIPA, unless, and only to the extent that, the court
determines upon application that, in view of all the circumstances of the case,
the proposed indemnitee is fairly and reasonably entitled to indemnity for such
expenses as the court deems proper.

     The LIPA Articles provide further that (1) the determination to indemnify,
unless that determination is made by a court in the case of an action brought by
or on behalf of LIPA, shall be made by the board of directors, or a committee
thereof, acting by a majority vote of a quorum consisting of directors who were
not parties or otherwise involved in the action giving rise to the proposed
indemnification, or, if a quorum is not obtainable and the board of directors so
directs, by independent legal counsel, or by the shareholders; (2) expenses
incurred in defense of an action may be paid in advance by LIPA, subject to an
agreement by the officer or director to reimburse LIPA if he or she is
ultimately determined not to be entitled to indemnification; and (3) to the
extent that any director, officer, employee or agent of LIPA has been successful
on the merits or otherwise in defense of any action, suit or proceeding, whether
civil, criminal, administrative or investigative, such person must be
indemnified against reasonable expenses incurred by him in connection therewith.

     The MBCA contains provisions setting forth conditions under which a
corporation may indemnify its directors, officers, and employees.  Although
indemnification is permitted only if certain statutory standards of conduct are
met, the MBCA provides for indemnification if the person acted in good faith and
in a manner the person 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 the conduct was unlawful.
Indemnification of officers, directors and employees is mandatory under the
MBCA.  The advancement of expenses is mandatory under the MBCA.  The MBCA
requires that a corporation report any indemnification payments to its
shareholders no later than the next meeting of shareholders.

PAYMENT OF DIVIDENDS

     Pursuant to the LBCL, the board of directors may from time to time declare
dividends in cash, property or its own shares out of surplus, except earned
surplus reserved by the board of directors, unless the corporation is insolvent
or would thereby be made insolvent or the declaration or payment of the dividend
would be contrary to any restrictions contained in the articles of incorporation
or by-laws.  If the corporation does not have surplus available for dividends,
it may pay dividends out of its net profits for the then current or the
preceding fiscal year or both.  However, no dividend may be paid at a time when,
either before or after the payment of the dividend, the corporation's
liabilities exceed its assets or the net assets are less than the aggregate
amount payable on liquidation upon the issued shares, if any, which have a
preferential right to participate in the corporation's assets in the event of
liquidation.  No dividends may be paid in shares, other than treasury shares,
except upon transfer to stated capital from capital surplus of (1) an amount not
less than the aggregate par value of the issued par value shares and (2) such
amount as the board of directors of the corporation may determine in respect of
issued shares without par value.  No dividend payable in shares of any class
shall be paid to stockholders of any other class, unless the articles of
incorporation so permit or such payment is authorized by the holders of a
majority of the shares of the class in which the payment is to be made.
     
                                       -73-  
<PAGE>

     The MBCA provides that a corporation may make a distribution only if it is
able to pay its debts in the ordinary course of business after making the
distribution.

ANTI-TAKEOVER PROTECTION

     Although the LIPA Articles and the LIPA Bylaws contain no specific anti-
takeover provisions, the LCBL provides certain anti-takeover protections (See "-
Vote on Merger, Consolidation or Sale of Substantially All Assets").  In
addition it should be noted that the LIPA Articles provide for a staggered board
of directors, and the LIPA Bylaws provide for certain restrictions on the voting
rights of holders of common stock.  (See "-Number of Directors" and "DESCRIPTION
OF LIPA COMMON STOCK").

     Although the MBCA contains a control share acquisition statute, the United
Articles make this statute inapplicable to United.

     The MBCA also provides that during any tender offer, a publicly held
corporation may not enter into or amend an agreement (whether or not subject to
contingencies) that increases the current or future compensation of any officer
or director.  In addition, under the MBCA, a publicly held corporation is
prohibited from purchasing any voting shares owned for less than two years from
a 5% shareholder for more than the market value unless the transaction has been
approved by the affirmative vote of the holders of a majority of the voting
power of all shares entitled to vote, or unless the corporation makes a
comparable offer to all holders of shares of the class or series of stock held
by the 5% shareholder and to all holders of any class or series into which such
securities may be converted.

     It should be noted that in addition to the anti-takeover measure discussed
above, the provisions in (1) the United Bylaws providing for a staggered board
of directors and requiring advance notice of director nominations (discussed
above under "Number of Directors"), (2) the United Articles providing that the
affirmative vote of the holders of two-thirds of the outstanding United Common
Stock is required in order to amend provisions of the United Articles concerning
the election and removal of directors, and that the affirmative vote of the
holders of two-thirds of the outstanding shares of capital stock entitled to
vote generally in the election of directors is required in order to amend
provisions concerning certain mergers, consolidations and other business
combinations and reorganizations (See "-Amendment of Articles of
Incorporation"), (3) the United Bylaws limiting the right of shareholders to
call a special meeting of shareholders to consider a business combination or any
action to change or otherwise affect the composition of the Board of Directors
by requiring the request of holders of at least 25% of the outstanding shares
(see "--Special Meetings of Shareholders"), (4) the United Articles providing
that shareholders may not cumulate their votes in the election of directors, and
(5) the United Articles providing that the Board of Directors can, without
shareholder approval, issue preferred shares with voting, conversion and other
rights which could adversely affect the voting power of the holders of United
Common Stock (see "DESCRIPTION OF UNITED CAPITAL STOCK-United Preferred Stock"),
may make it more difficult to effect a change in control of United and may
discourage or deter a third party from attempting a takeover.

DISSENTERS' RIGHTS

     Under the MBCA, a shareholder is entitled to dissent from many corporate
actions, including an amendment to the articles of incorporation which
materially and adversely affects the rights or preferences of shares held by the
dissenting shareholder, a disposition of all or substantially all of the
corporation's property and assets, a plan of merger with respect to which the
shareholder may vote, and a plan of exchange involving the acquisition of the
corporation's shares.  This remedy is an exclusive remedy, except where the
corporate action involves fraud.

                                       -74-
<PAGE>

     Under the LBCL, a shareholder is entitled to dissent from certain corporate
actions, including the sale, lease or exchange of substantially all of the
corporation's assets, or a merger or consolidation involving the corporation, if
the action taken is not approved by the holders of at least 80% of LIPA Common
Stock entitled to vote thereon.


                      DESCRIPTION OF UNITED CAPITAL STOCK

UNITED COMMON STOCK
    
     United is authorized by the United Articles to issue 500,000,000 shares of
Common Stock, par value $.01 per share, of which 175,512,080 shares were issued
and outstanding as of March 31, 1996 and which were held of record by 5,948
shareholders.  Holders of shares of United Common Stock are entitled to one vote
per share on all matters to be voted on by shareholders.  United shareholders
are not entitled to cumulate their votes in the election of directors.  The
holders of United Common Stock are entitled to receive such dividends, if any,
as may be declared by the Board of Directors in its discretion out of funds
legally available therefor.  Subject to the rights of any preferred stock
outstanding, upon liquidation or dissolution of United, the holders of United
Common Stock are entitled to receive on a pro-rata basis all assets remaining
for distribution to shareholders.  Shares of United Common Stock do not have
preemptive or other subscription or conversion rights (or redemption or sinking
fund provisions).  All of the outstanding shares of United Common Stock are, and
shares of United Common Stock to be issued as described in this Proxy Statement-
Offering Circular will be, fully paid and nonassessable.     

UNITED PREFERRED STOCK

     United's Board of Directors is authorized to issue preferred stock in one
or more series and to fix the voting rights, liquidation preferences, dividend
rights, conversion rights, redemption rights and terms, including sinking fund
provisions and certain other rights and preferences, of the preferred stock.
The Board of Directors of United can, without shareholder approval, issue shares
of such preferred stock with voting and conversion rights which could adversely
affect the voting power of the holders of United Common Stock and may have the
effect of delaying, deferring or preventing a change in control of United.
    
     United is authorized by the United Articles to issue 10,000,000 shares of
Preferred Stock, par value $.001 per share, 500,000 of which were issued and
outstanding as of March 31, 1996.  The 500,000 shares of United preferred
stock outstanding, as set forth in a certificate of designations, are 5.75%
Series A Convertible Preferred Stock, par value $.001 (the "Convertible
Preferred Stock").  Holders of Convertible Preferred Stock are entitled to a
liquidating distribution of $1,000 per share (the "Liquidation Preference"),
plus any accrued dividends, and rank senior to United Common Stock with respect
to rights to receive dividends and rights to receive distributions upon the
liquidation or dissolution of United.  Dividends are cumulative and payable
quarterly at an annual rate of 5.75% of the Liquidation Preference.  Holders of
Convertible Preferred Stock are not entitled to any other dividends.  The
holders of Convertible Preferred Stock have the right to convert each of their
shares into a number of shares of United Common Stock equal to the Liquidation
Preference divided by a conversion price.  The conversion price is $49.48, but
is subject to adjustment as set forth in the certificate of designations.  On or
after October 1, 1998, United may redeem the Convertible Preferred Stock in
whole or in part at a redemption price per share between 100.575% and 104.025%
of the Liquidation Preference, depending on the date of redemption.  On October
1, 2005, United must redeem the Convertible Preferred Stock then outstanding at
a price per share equal to the Liquidation Preference.  For as long as United is
in arrears on six quarterly dividends or has failed to pay any optional or
mandatory redemption amount, the number of Directors of United will be increased
by two, and the holders of the Convertible Preferred Stock will be entitled to
elect the additional directors.  The      
    
                                       -75-
<PAGE>

     
approval of 66-2/3% of the holders of the outstanding shares of Convertible
Preferred Stock is required before United may (1) create capital stock with
rights to receive dividends or a liquidation preference senior to the
Convertible Preferred Stock; (2) change any provision of the United Articles of
Incorporation or any certificate of designations with the effect of changing the
number of authorized shares of Convertible Preferred Stock, changing the par
value thereof or adversely affecting the rights and privileges of the holders of
Convertible Preferred Stock. The holders of Convertible Preferred Stock
otherwise have no voting rights. Holders of the Convertible Preferred Stock are
not entitled to any preemptive rights to acquire shares of United capital stock.
United may only repurchase, redeem or retire United Common Stock if full
cumulative dividends on the Convertible Preferred Stock have been paid, or
declared and set apart for payment. All of the outstanding shares of Convertible
Preferred Stock are fully paid and nonassessable.     

SPECIAL VOTING RIGHTS

     The Board of Directors of United is divided into three classes as nearly
equal in number as possible, with each class serving for a three-year term.  One
of the three classes of the Board of Directors is elected each year.  The United
Articles and United Bylaws require the affirmative vote of not less than two-
thirds of the outstanding shares of United Common Stock or the affirmative vote
of two-thirds of the directors in office at the time such vote is taken in order
to remove a director from office.

     The United Articles require the affirmative vote of two-thirds of the
outstanding shares of voting capital stock to approve certain transactions with
a person holding 20% or more of the United Common Stock, including any merger,
consolidation, sale, transfer or other disposition of a substantial portion of
United's assets, issuances of securities or certain reclassifications of
securities or recapitalizations, unless such transaction or such person's
acquisition of 20% or more of the United Common Stock is approved in advance by
two-thirds of the members of the Board of Directors who were directors prior to
the potential acquirer's obtaining 20% or more of the shares of United Common
Stock, or unless certain fair price considerations are met.

     United's authorized but unissued United Common Stock and preferred stock
might also be issued in such a fashion as would prevent or deter a change in
control.  The effect of these provisions could be to delay or prevent attempts
by other corporations or groups to acquire control of United without negotiation
with management.

TRANSFER AGENT AND REGISTRAR

     United's transfer agent and registrar is Norwest Bank Minnesota, N.A.,
Minneapolis, Minnesota.


                       DESCRIPTION OF LIPA CAPITAL STOCK
    
     LIPA is authorized by the LIPA Articles to issue 5,000 shares of Common
Stock, no par value, of which 418 shares were issued and outstanding as of March
31, 1996, and which were held of record by 411 shareholders.  The LIPA Common
Stock is not traded on any public trading market.  Holders of LIPA Common Stock
are entitled to one vote per share on all matters to be voted on by
shareholders.  The holders of LIPA Common Stock do not have preemptive rights
and are not entitled to cumulate their votes in the election of directors.  Only
physicians active in the practice of medicine and licensed by the State of
Louisiana, or dentists who specialize in oral surgery and who are members in
good standing of the American Society of Oral and Maxillofacial Surgeons may
qualify initially as shareholders.     
    
                                       -76-
<PAGE>

     The LIPA Articles set forth certain restrictions on the transferability of
LIPA Common Stock that apply in the event a shareholder dies, divorces, wishes
to sell his or her LIPA Common Stock, or ceases to be a participating physician
in one of LIPA's HMO subsidiaries.  Transfers arising in these situations are
subject to approval by the Board of Directors and qualification of the
transferee as a shareholder under the LIPA Bylaws.  If the transfer is not, or
cannot be, consummated in accordance with the procedures set forth in the LIPA
Articles, then LIPA has the option to redeem the share or shares at current book
value to be paid out with interest over a two-year period.


                                 LEGAL MATTERS

     The validity of the United Common Stock to be issued in connection with the
Merger will be passed upon by Kevin H. Roche, General Counsel of United.   The
opinion of counsel described under "THE MERGER-Certain Federal Income Tax
Consequences," will be rendered by Dorsey & Whitney LLP, Pillsbury Center South,
220 South Sixth Street, Minneapolis, MN  55402-1498.  The opinion of LIPA's
counsel to be delivered in connection with the Merger Agreement will be rendered
by Thomas H. Benton & Associates, 601 St. Ferdinand Street, Baton Rouge, LA

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors of Louisiana Independent Physicians Association, Inc.:

We have audited the accompanying consolidated balance sheets of Louisiana
Independent Physicians Association, Inc. (a Louisiana corporation) as of
December 31, 1995 and 1994, and the related consolidated statements of
operations, shareholders' equity, and cash flows for each of the three years in
the period ended December 31, 1995.  These financial statements are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audits to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation.  We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Louisiana Independent
Physicians Association, Inc. as of December 31, 1995 and 1994, and the results
of its operations and its cash flows for each of the three years in the period
ended December 31, 1995 in conformity with generally accepted accounting
principles.

              LOUISIANA INDEPENDENT PHYSICIANS ASSOCIATION, INC.
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     ORGANIZATION OWNERSHIP AND BASIS OF PRESENTATION -

     Louisiana Independent Physicians Association, Inc., (LIPA), a physician
     owned holding company, provides health care services to its majority owned
     subsidiary, Community Health Network of Louisiana, Inc. (CHN), which is a
     for-profit health maintenance organization (HMO) which offers its enrollees
     a variety of managed care programs and products through contractual
     arrangements with health care providers.  CHN has entered into contracts
     with physicians, hospitals and other health care providers pursuant to
     which, such providers deliver medical care to CHN enrollees on a modified
     fee-for-service basis.

     CHN is subject to regulation by the Louisiana Department of Insurance, and
     is required to maintain minimum equity levels, as defined.  In addition,
     all dividends paid by CHN to its shareholders must be approved by the
     Louisiana Department of Insurance.

     The accompanying consolidated financial statements include the accounts of
     LIPA and its majority-owned subsidiary, CHN, (collectively referred to as
     the Company).  All significant intercompany transactions are eliminated in
     consolidation.

     LIPA and CHN have entered into an Administrative Management Contract and
     Master Agreement with Complete Health Partners, Inc. (CHP), an indirect
     wholly owned subsidiary of United HealthCare Corporation (UHC), and
     Louisiana Health Management Company (LHMC or the Partnership), a general
     partnership, under which these entities provide administrative management
     services to CHN (see Note 2).  LIPA owns 48.51% of the Partnership; the
     remaining interest in the Partnership is 50.49% owned by CHP, and 1% owned
     by Louisiana Health Partners, Inc. (LHP), an HMO management corporation.
     LHP is, in turn, 49% owned by LIPA and 51% owned by CHP.

     USE OF ESTIMATES -

     These financial statements have been prepared in accordance with generally
     accepted accounting principles, which require the use of certain estimates,
     the most significant of which relate to incurred but not yet reported
     claims for medical services.

     REVENUE RECOGNITION -

     Premium revenues are recognized in the period in which enrollees are
     entitled to receive health care services.  Premiums received prior to the
     period of service are recorded as unearned premiums.

     CASH AND CASH EQUIVALENTS -

     Cash and cash equivalents consist primarily of certificates of deposits and
     repurchase agreements with original maturities of three months or less.

     Included in cash and cash equivalents at December 31, 1994 is $358,000
     which has been withheld by CHN from payments to providers under the claims
     administration agreement entered into with the City of Baton Rouge.  This
     agreement was terminated effective January 1, 1995, and the cash withheld
     was returned to the providers.  Also included in restricted cash at
     December 31, 1995 and 1994 is $118,000, which represents collateral for
     appeal of a prior legal judgement against CHN.

     RESTRICTED CASH RESERVES -

     CHN is required by Louisiana regulations to maintain minimum cash reserves.
     These restricted cash reserves consist principally of certificates of
     deposit and are stated at amortized cost which approximates market value.
     These reserves are classified as a noncurrent asset as they are not
     available for working capital purposes.  Interest earned on these reserves
     accrues to the Company.

     MEDICAL SERVICES EXPENSES -

     Medical services expenses include claims paid, claims in process and
     pending, and unreported claims and charges by physicians, hospitals and
     other health care providers for services rendered to enrolled members
     during the period.  Medical cost adjustments to prior period estimates are
     reflected in the current period and changes to these estimates could be
     significant.

     An agreement between LIPA, CHP, and CHN contains a provision that makes
     LIPA responsible for funding 50% of CHN's health care cost overruns
     (defined as the excess of actual health care costs over funds for such
     costs).  In connection with this agreement for the year ended December 31,
     1995, LIPA and CHP funded health care cost overruns of $5,155,000.  The 50%
     funding received form CHP is reflected as a reduction to medical services
     expenses in the accompanying 1995 consolidated statement of operations and
     retained earnings and is included as a receivable from affiliated in the
     accompanying 1995 consolidated balance sheet.  There were no health care
     cost overruns reimbursed by LIPA or CHP under this agreement in 1994.

     In addition, CHN contracts with shareholders of LIPA to provide health care
     services.  Approximately $20,900,000, $17,274,000 and $17,647,000 of
     medical services expenses included in the accompanying statements of
     operations for the years ended December 31, 1995, 1994 and 1993, and a
     portion of medical claims payable at December 31, 1995 and 1994 is related
     to these providers.

     MAJOR CUSTOMERS -

     One customer group accounted for 30%, 35% and 42% of total CHN enrollment
     and 22%, 32% and 40% of total premiums for 1995, 1994, and 1993.

     PHYSICIAN INCENTIVES -

     Participating physicians were eligible to receive payment for health care
     services that did not exceed predetermined fee maximums for each unit of
     service provided and a percentage of each participating physician's
     reimbursement was held as a Physician Incentive Allowance (PIA), the
     purpose of which was to provide an incentive for the physicians to
     appropriately manage medical costs.  The Company returned approximately
     $747,000 and $577,000 of PIA for the contract years ended December 31, 1994
     and 1993.

     RECLASSIFICATIONS -

     Certain 1994 and 1993 amounts in the consolidated financial statements have
     been reclassified to conform with the 1995 presentation.  These
     reclassifications had no effect on net income or shareholders' equity as
     previously reported.

2.   OPERATING AGREEMENTS

     Pursuant to the terms of an Administrative Management Contract, the
     Partnership provides management services to CHN for a fee based on CHN's
     premium revenues.  CHN also pays an amount equal to the interest due on the
     Partnership's notes to CHN, which totaled $34,000 in 1995,  $35,000 in 1994
     and $85,000 in 1993 and is included in interest and other revenue in the
     accompanying consolidated statements of operations.

                                      F-9
<PAGE>
  
     Under the terms of the Master Agreement, CHN sold certain of its business
     rights to the Partnership (see Note 1) in exchange for a ten-year
     promissory note with a face value of $500,000 bearing interest at an annual
     rate of 8%.  The note is payable semi-annually through May 1, 2000, and is
     included in Notes Receivable - Affiliate in the accompanying consolidated
     balance sheets at its discounted value based upon a market interest rate at
     November 1, 1988, less payments made.  As a part of this Master Agreement
     CHN's employees became employees of the Partnership.

     Effective October 1, 1994, CHN contracted with Diversified Pharmaceutical
     Services, Inc. (Diversified), to provide pharmacy management and claims
     processing services for its enrollees.  UHC signed a six-year management
     services agreement with Diversified's parent which requires CHN, subject to
     competitive cost and quality considerations, to continue to utilize the
     Diversified drug benefit management services required in CHN's operations.
     At the end of the six-year period, the parties will consider continuation
     of the contract.  Prior to October 1, 1994, CHN had a contract with Rx
     Management, Inc., a wholly owned subsidiary of Complete Health Services,
     Inc. (CHS), and fees related to this agreement approximated $52,000 in 1994
     and $328,000 in 1993.

3.   INCOME TAXES

     CHN and LIPA file separate federal and state income tax returns.  The
     provision for (benefit from) income taxes consists of the following:

     The differences between income taxes computed using the federal statutory
     rate and the effective tax rate were as follows:

                                         ========   ========    ========
</TABLE>

     Deferred income taxes relate principally to differences in the method of
     recording medical services expenses for book and tax purposes and the
     utilization of net operating losses.

4.   REINSURANCE AGREEMENT

     The Company has a reinsurance agreement with Lincoln National Health &
     Casualty Insurance Company to cover hospital inpatient claims in excess of
     certain limits.  Reinsurance premiums, net of recoveries, of approximately
     $278,000 in 1995, $377,000 in 1994 and $123,000 in 1993, are included in
     medical services expenses in the accompanying statements of operations.

5.   COMMITMENTS AND CONTINGENCIES

     LITIGATION -

     CHN is involved in legal actions which arise in the ordinary course of its
     business.  While the outcome of these actions is not presently
     determinable, it is the opinion of management that the ultimate resolution
     of these claims will not have a material adverse effect on the consolidated
     financial position or results of operations of the Company.

     CONCENTRATION OF CREDIT RISKS -

     At December 31, 1995, substantially all of the Company's cash and cash
     equivalents were maintained by a bank in Baton Rouge, Louisiana.  The
     Company periodically considers the financial condition of its depository
     bank.

     CHN, a majority owned subsidiary of LIPA and an affiliate of LHP, is
     required to obtain a performance bond in accordance with the contract with
     the State of Louisiana Employer Group Benefits Program (the Program).
     Accordingly, CHN paid UHC $27,000 to obtain a performance bond on its
     behalf from St. Paul Fire and Marine Insurance Company in the amount of
     $3,830,000.  This bond was renewed June 30, 1995 at a cost of approximately
     $35,000.  Additionally, the bond was increased to $4,560,000, effective
     until June 30, 1996.  UHC has agreed to indemnify the St. Paul Fire and
     Marine Insurance Company for any losses under the bond.  In return, LHP has
     pledged the proceeds from CHN's accounts receivable from the Program as
     collateral for any loss UHC might incur.

6.   SUBSEQUENT EVENT

     In January 1996, LIPA and UHC entered into a definitive merger agreement
     (the "Merger Agreement") whereby LIPA would become an indirect wholly owned
     subsidiary of UHC.  Under the terms of the Merger Agreement, each
     outstanding share of LIPA common stock will be converted into the right to
     receive a pro rata allotment of an aggregate number of shares of UHC common
     stock, subject to adjustment for the average per share closing price of UHC
     common stock as reported on the New York Stock Exchange, Inc. leading up to
     the closing date of the merger.  Consummation of the merger is subject to
     various conditions, including among other things, the approval by LIPA
     shareholders of the merger, receipt by LIPA and UHC of opinions of counsel
     as to the treatment of the merger as tax-free reorganization for federal
     income tax purposes; and other customary closing conditions.  The
     transaction is anticipated to close in the second quarter of 1996.

    NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINING FINANCIAL INFORMATION

A.  Included in this 1995 historical United information are the results of the
MetraHealth Business ("MetraHealth") for the three month period ended December
31, 1995.

B.  This information includes the historical results of the MetraHealth
operations for the nine month period ended September 30, 1995 and the
corresponding pro forma adjustments to give effect to what United's operations
would have been had MetraHealth been included in United's historical financial
results for the full year ended December 31, 1995.

C.  This adjustment reflects the reduction in interest income as a result of
cash paid in the acquisition of $1.09 billion ($1.09 billion at 6.0% per annum).

D.  This adjustment reflects the amortization of costs in excess of net assets
acquired resulting from the acquisition of $992.0 million, using a range of
estimated useful lives for identifiable and unidentifiable intangible assets of
25 to 40 years (35 year average assumed).

E.  This adjustment reflects the estimated net tax effects of the pro forma
adjustments described herein for the respective periods using United's
consolidated effective tax rate.  This adjustment assumes that the amortization
of costs in excess of net assets acquired resulting from the transaction are not
deductible.

F.  This adjustment reflects the dividends on the 5.75% convertible preferred
stock issued in connection with the acquisition.  In determining earnings per
share, the preferred stock is not considered a common stock equivalent and is
antidilutive.

G.  Certain amounts in the HealthWise historical financial information have been
reclassified to conform with United's financial presentation.

H.  Does not include one-time estimated United and HealthWise non-operating
costs associated with the Merger of approximately $13 million.  These non-
operating costs, which will be expensed in the period in which the Merger is
consummated, include legal, accounting and financial advisor fees, printing and
mailing charges, and SEC filing and stock exchange fees.  United also expects to
incur substantial non-operating expenses in addition to these transaction costs.
The additional non-operating, expenses may include charges with respect to the
elimination of duplicate functions and facilities, severance costs relating to
terminating certain employees and the write-off of certain assets.  Such
additional non-operating costs will be expensed in the period in which the
Merger is consummated.

I.  The combined pro forma net earnings per common share data is computed by
dividing pro forma net earnings by the weighted average number of common shares
and common share equivalents of the combined companies.

J.  As United had previously consolidated LIPA, the Pro Forma adjustments only
reflect those entries necessary to adjust United's statements of operations for
the amortization of the excess purchase price and elimination of minority
interest earnings.

K.  This adjustment reflects the amortization of costs in excess of net assets
acquired resulting from the acquisition of $56 million using an estimated useful
life of 40 years.

L.  This adjustment adds back the earnings from operations attributable to
minority interests.

M.  United acquired PHP, Inc. on March 29, 1996 and in a separate transaction
signed a definitive agreement to acquire Physicians Health Association, ltd.,
which is expected to close in the second quarter of 1996.  These transactions
have been excluded from the "UNAUDITED PRO FORMA CONDENSED COMBINING FINANCIAL
INFORMATION" as their effects are not significant.

     This First Amendment ("Amendment") to the Agreement and Plan of Merger
dated January 16, 1996 by and among United HealthCare Corporation, UHC Gold
Acquisition, Inc. and Louisiana Independent Physicians Association, Inc. (the
"Agreement"), is made this 24th day of April, 1996. All capitalized terms herein
are used as defined in the Agreement.

                                   RECITALS

     Section 2.04(i) of the Agreement provided that Acquiror will present to the
Shareholder Representative a calculation of the aggregate Earn-Out with respect
to each Earn-Out Year within 90 days following the end of such year. The parties
to the Agreement have determined that, for purposes of calculation of the Earn-
Out, certain payment lag data necessary to support the calculation will not be
available to provide an acceptable level of accuracy in the calculation before
90 days after the end of each Earn-Out Year. Therefore, the parties to the
Agreement desire to extend the time within which the calculation of the
aggregate Earn-Out is presented to the Shareholder Representative, to specify
that such calculation takes into account accurate payment lag data and to adjust
accordingly the date by which payment is due.

                                   AGREEMENT

     In consideration of the foregoing, the parties hereto hereby agree as
follows:

     1. Section 2.04(a) of the Agreement is hereby amended so as to read in its
entirety as follows:

          (a) Each Contingent Payment Right shall represent only a right to
receive a cash payment (the "Earn-Out") from Acquiror, subject to the terms set
forth in this Section 2.04 and Acquiror's right of offset under Article IX of
this Agreement. The amount of any Earn-Out payment payable with respect to each
Contingent Payment Right shall be equal to the aggregate Earn-Out payment
payable, calculated as set forth below, divided by the total number of
Contingent Payment Rights outstanding as of the date such payment is due. The
amount of the Earn-Out payment payable for each Earn-Out Year (as defined
below), if any, shall be calculated by Acquiror as set forth in this Section
2.04 and paid not later than 30 days following delivery to the Shareholder
Representative, as defined in Section 2.04(k), of the calculation of the
aggregate Earn-Out as provided in Section 2.04(i). Contingent Payment Rights
shall not possess any attributes of common stock or other security and shall not
entitle the holders of the Contingent Payment Rights to any rights of any kind
other than as specifically set forth in this Agreement. Subject to Section
2.04(j), all payments of the Earn-Out shall be made net of any amount for which
Acquiror is entitled to indemnification under Article IX of this Agreement.     

                                     AA-1
<PAGE>
 
    
     2. Section 2.04(i) of the Agreement is hereby amended so as to read in its
entirety as follows:

          (i) Within 120 days following the end of each Earn-Out Year, Acquiror
     will deliver to the Shareholder Representative, as defined in Section
     2.04(k), a calculation of the aggregate Earn-Out with respect to such Year,
     together with the certification of the chief financial officers of Acquiror
     and the Surviving Corporation to the effect that the provisions of Section
     2.04(h) have been complied with, and the further certification of such
     officers and the independent certified public accountants of Acquiror or
     the Surviving Corporation to the effect that the calculation shown therein
     is in accordance with an audit by such accountants of the Community Health
     Entities, with the adjustments provided for in Exhibit 2.04 and the
     following sentence. The calculation of the aggregate Earn-Out with respect
     to each such year shall be based upon payment lag data available as of a
     date not less than 90 days from the end of such year. A copy of the audit
     shall be delivered to the Shareholder Representative, together with such
     other information reasonably related to the calculation of the Earn-Out as
     the Shareholder Representative may reasonably request. The Shareholder
     Representative will be deemed to have accepted such calculation and to have
     waived forever any right to contest it unless it notifies Acquiror within
     60 days after delivery of the calculation to the Shareholder Representative
     that such Representative contests such calculation and the reasons
     therefor. Any such contest which cannot be resolved within 30 days by
     Acquiror and the Shareholder Representative shall be resolved by
     arbitration in the manner provided in Section 11.01, except that the third
     arbitrator shall be a member of a nationally recognized accounting firm.
     Acquiror shall make the Earn-Out payment required pursuant to Section
     2.04(a) when due notwithstanding the pendency of any such contest, except
     that until such contest shall have been finally determined Acquiror shall
     be required to pay only the amount reflected in its calculation. Any
     remaining amount determined to be due by the arbitrators, or any other
     amount not paid by the due date, shall bear interest at the rate provided
     for in Section 9.05 from the original due date until paid.

     3. The last sentence of paragraph no. 2 of Exhibit 7.02(e) to the Agreement
is hereby amended to read as follows:

     As to any conflicts of ownership that are reflected in Schedule 3.03 or
     that have developed since the date of the Agreement, counsel for the
     Company, as of the Effective Time, has identified all such conflicts and
     either certified to Acquiror the proper ownership of the related Company
     Common Stock or made available to Acquiror all information known to counsel
     relating to the conflict.    
                                     AA-2
<PAGE>
 
    
     4. All other provisions of the Agreement shall remain in full force and
effect.

     IN WITNESS WHEREOF, the parties have executed this Amendment as of the date
on the first page.

     THIS AGREEMENT AND PLAN OF MERGER, dated as of JANUARY 16, 1996 (this
"Agreement"), is by and among UNITED HEALTHCARE CORPORATION, a Minnesota
corporation ("Acquiror"), UHC GOLD ACQUISITION, INC., a Louisiana corporation
and a wholly owned Subsidiary of Acquiror ("Acquiror Sub"), and LOUISIANA
INDEPENDENT PHYSICIANS ASSOCIATION, INC., a Louisiana corporation (the
"Company"). Capitalized terms used and not otherwise defined herein have the
meanings set forth in Article X.

                                    RECITALS
                                    --------

     The following recitals summarize the principal terms of this Agreement and
the transactions contemplated by this Agreement, are intended for convenience
only, shall not be accorded any legal significance, and are qualified in their
entirety by reference to the terms and conditions set forth in this Agreement
and the schedules, exhibits and other agreements attached to, or contemplated
by, this Agreement:

                               Current Structure
                               -----------------

     1.  The Company is a holding company which owns (a) 51% of the common
stock of Community Health Network of Louisiana, Inc., a Louisiana corporation
("CHN"), (b) a 48.51% general partnership interest in Louisiana Health
Management Company, a Louisiana general partnership ("LHMC"), and (c) 49% of the
common stock of Louisiana Health Partners, Inc., a Louisiana corporation and the
1% owner and managing general partner of LHMC ("LHP").  CHN, LHMC and LHP are
referred to herein as the "Community Health Entities."

     2.  Acquiror, indirectly through one or more wholly owned subsidiaries, 
owns (a) 49% of the common stock of CHN, (b) a 50.49% general partnership
interest in LHMC and (c) 51% of the common stock of LHP.

                                   The Merger
                                   ----------

     3.  The outstanding capital stock of the Company is held by over 400
persons, each of whom is a medical services provider to, or an employee of, the
HMO operated by CHN.  Acquiror has agreed to acquire the Company by means of the
merger of the Company with and into Acquiror Sub, with Acquiror Sub being the
surviving corporation (the "Merger").

     4.  Upon consummation of the Merger, the Company's shareholders will in the
aggregate receive:

     (a) a number of shares of Acquiror's Common Stock, $.01 par value per share
("Acquiror Common Stock") equal to $50 million divided by the average closing
price of the Acquiror Common Stock on the NYSE calculated for the ten trading
days ending two trading days prior to the closing of the Merger, subject to
adjustments in certain instances herein provided; and


<PAGE>
 
     (b) cash earn-out payments in an amount ranging from $0 to $35 million,
which payments will be made to the extent, if any, that the level of the
Company's net income during 1996 and 1997 exceeds certain specified targets. For
purposes of calculating the earn-out payments, the Company's net income will be
adjusted as set forth in Exhibit 2.04(e) to cap certain operation expenses based
on a percentage of premium revenues and to include the results of operations of
the Louisiana HMO business of The MetraHealth Companies (acquired by Acquiror in
October 1995).

                     Registration of Acquiror Common Stock
                     -------------------------------------

     5.  Acquiror, as sole shareholder of Acquiror Sub, will deliver or cause to
be delivered, to the shareholders of the Company the consideration to be issued
or paid pursuant to the Merger. The Acquiror Common Stock issued in the Merger
will be registered with the SEC pursuant to a Form S-4 Registration Statement
filed by Acquiror and, following the Merger, will be freely transferable subject
to Rule 145 under the Securities Act.

                            Tax Treatment of Merger
                            -----------------------

     6.  For federal income tax purposes, it is intended that the Merger
qualify as a reorganization under the provisions of Section 368(a) of the Code,
with the result that the value of the whole number of shares of Acquiror Common
Stock issued in the Merger will not be taxable to the Company's shareholders
until such shares are disposed of by such shareholders. Earn-out payments, if
any, will be taxable to the Company's shareholders upon receipt.

                          Indemnification of Acquiror
                          ---------------------------

     7.  Acquiror is entitled to indemnification for certain items identified in
this Agreement. Acquiror has the right to offset amounts for which it is
entitled to indemnity against the cash earn-out payments described above.
Acquiror's right to recovery is limited to this right of offset.

                       Principal Conditions to the Merger
                       ----------------------------------

     8.  As a condition to the Merger, Acquiror has required, among other
things, that:

     (a) certain persons enter into consulting and noncompetition
arrangements with Acquiror, in return for which Acquiror will make certain
payments to such persons;

     (b) the shareholders of the Company waive any claims against the Company
and the Community Health Entities arising from their relationship as medical
services providers; and

                                      A-2
<PAGE>
 
     (c) less than 10% of the Company's shareholders exercise dissenters'
rights regarding the Merger.

     9.  The closing of the Merger is also subject to a number of other
conditions, including approval of the Merger by the Company's shareholders,
receipt of all required regulatory and third party approvals, absence of
litigation regarding the Merger, and the delivery of certain legal opinions and
other documents at closing.

                               Approval of Merger
                               ------------------

     10.  The boards of directors of Acquiror, Acquiror Sub and the Company
have approved this Agreement and the Merger. Acquiror, as sole shareholder of
Acquiror Sub, has also approved this Agreement and the Merger. The Company has
agreed to hold a special meeting of its shareholders for the purpose, among
other things, of approving this Agreement and the Merger, and the closing of the
Merger is subject to the receipt of such approval.

     NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth in this
Agreement, and subject to the terms and conditions hereof, the parties agree as
follows:

                                   ARTICLE I
                                   THE MERGER

     SECTION 1.01  The Merger.  Upon the terms and subject to the conditions 
set forth in this Agreement, and in accordance with Louisiana Law, at the
Effective Time (as defined in Section 1.02) the Company shall be merged with and
into Acquiror Sub. As a result of the Merger, the separate corporate existence
of the Company shall cease and Acquiror Sub shall continue as the surviving
corporation of the Merger (the "Surviving Corporation"). Acquiror Sub and the
Company are sometimes collectively referred to herein as the "Constituent
Corporations".

     SECTION 1.02  Effective Time.  Provided this Agreement shall not have been 
terminated as provided in Article VIII, the parties shall cause the Merger to be
consummated on the Closing Date (as defined in Section 1.07) by executing and
filing a certificate of merger substantially in the form of Exhibit 1.02 hereof
(the "Articles of Merger") with the Secretary of State of the State of
Louisiana, all in accordance with the relevant provisions of Louisiana Law (the
date and time of such filing being the "Effective Time").

     SECTION 1.03  Effect of the Merger.  At the Effective Time, the effect of 
the Merger shall be as provided in the applicable provisions of Louisiana Law.
Without limiting the generality of those laws, and subject to their provisions,
at the

                                      A-3
<PAGE>
 
Effective Time, except as otherwise provided in this Agreement, all the
property, interests, assets, rights, privileges, immunities, powers, franchises
and authorities of Acquiror Sub and the Company shall vest in the Surviving
Corporation, and all debts, liabilities, duties and obligations of Acquiror Sub
and the Company shall become the debts, liabilities, duties and obligations of
the Surviving Corporation.

     SECTION 1.04  Articles of Incorporation; By-Laws.  At the Effective Time, 
the Articles of Incorporation and the By-Laws of Acquiror Sub, as in effect on
the date hereof and as otherwise amended prior to the Effective Time or pursuant
to the Articles of Merger, shall be the Articles of Incorporation and the By-
Laws of the Surviving Corporation.

     SECTION 1.05  Directors and Officers.  The directors of Acquiror Sub
immediately prior to the Effective Time shall be the initial directors of the
Surviving Corporation, each to hold office in accordance with the Articles of
Incorporation and By-Laws of the Surviving Corporation, and the officers of
Acquiror Sub immediately prior to the Effective Time shall be the initial
officers of the Surviving Corporation, in each case until their respective
successors are duly elected or appointed and qualified.

     SECTION 1.06  Taking Necessary Action; Further Action.  Acquiror, Acquiror 
Sub and the Company, respectively, shall each use its reasonable efforts as
promptly as possible to take all such action as may be necessary or appropriate
to effectuate the Merger under Louisiana Law at the time specified in Section
1.02. If, at any time after the Effective Time, any further action is necessary
or desirable to carry out the purposes of this Agreement and to vest the
Surviving Corporation with full right, title and possession to all properties,
interests, assets, rights, privileges, immunities, powers, franchises and
authority of either of the Constituent Corporations, the officers of the
Surviving Corporation are fully authorized in the name of each Constituent
Corporation or otherwise to execute and deliver or cause to be executed and
delivered such deeds and other instruments and to take or cause to be taken all
such further lawful and necessary action.

     SECTION 1.07  The Closing.  The closing of the transactions contemplated 
by this Agreement (the "Closing") shall take place at the offices of CHN, in
Baton Rouge, Louisiana, commencing at 10:00 a.m., local time, on the last
business day of the month during which all of the conditions to the Merger set
forth in Article VII shall have been fulfilled or waived in accordance herewith,
or such other date, time and place as the parties may agree (the "Closing Date")
and shall be effective at the Effective Time. Subject to the provisions of this
Agreement, at the Closing there shall be delivered to each of the parties the

                                   ARTICLE II
               CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES

     SECTION 2.01  Conversion of Securities.  At the Effective Time, by virtue 
of the Merger and without any further action on the part of Acquiror Sub, the
Company or the holders of the Company's Common Stock, no par value ("Company
Common Stock"):

     (a) Each share of Company Common Stock issued and outstanding immediately
prior to the Effective Time (other than any shares of Company Common Stock to be
canceled pursuant to Section 2.01(d) and other than Dissenting Shares (as
defined in Section 2.05)) shall be converted, subject to Section 2.02(e), into
and become the right to receive the following (collectively, the "Merger
Consideration"):

          (i) a number of shares of Acquiror Common Stock equal to:

               (A) if the Average Stock Price is at least $53.2656, but not more
          than $68.4844, the number obtained by dividing (x) the quotient of (1)
          $50,000,000 divided by (2) the Average Stock Price by (y) the number
          of shares of Company Common Stock outstanding at the Effective Time
          (excluding shares that are to be canceled pursuant to 2.01(d)) (the
          "Outstanding Company Shares"); or

               (B) if the Average Stock Price is more than $68.4844, but not
          more than $73.0500, the number obtained by dividing (x) 730,093, by
          (y) the Outstanding Company Shares; or

               (C) if the Average Stock Price is at least $49.2707, but less
          than $53.2656, the number obtained by dividing (x) 938,692, by (y) the
          Outstanding Company Shares; or

               (D) if the Average Stock Price is more than $73.0500, the number
          obtained by dividing (x) the quotient of (1) $53,750,000 divided by
          (2) the Average Stock Price by (y) the Outstanding Company Shares; or

               (E) if the Average Stock Price is less than $49.2707, the number
          obtained by dividing (x) the quotient of (1) $46,250,000 divided by
          (2) the Average Stock Price by (y) the Outstanding Company Shares; and

          (ii) one "Contingent Payment Right" having the rights and terms set 
     forth in Section 2.04;

     provided that payment of amounts in respect of Contingent Payment Rights
     shall be subject to Acquiror's right of offset set forth in Article IX of
     this Agreement.

                                      A-5
<PAGE>
 
     The foregoing formula for conversion of the Company Common Stock is
referred to as the "Exchange Ratio."

     (b) Notwithstanding the foregoing, if between the date of this Agreement
and the Effective Time the outstanding shares of Acquiror Common Stock or
Company Common Stock shall have been changed into a different number of shares
or a different class, by reason of any stock dividend, subdivision,
reclassification, recapitalization, split, combination or exchange of shares,
the Exchange Ratio shall be correspondingly adjusted to reflect such stock
dividend, subdivision, reclassification, recapitalization, split, combination or
exchange of shares.

     (c) All shares of Company Common Stock converted pursuant to the Merger
shall no longer be outstanding and shall automatically be canceled and retired
and shall cease to exist, and each certificate previously representing any such
shares shall thereafter represent the right to receive the Merger Consideration
into which such Company Common Stock was converted in the Merger and cash in
lieu of fractional shares of Acquiror Common Stock pursuant to Section 2.02(e).
Certificates previously representing shares of Company Common Stock shall be
exchanged for certificates representing whole shares of Acquiror Common Stock
issued in consideration therefor upon the surrender of such certificates in
accordance with the provisions of Section 2.02, without interest. No fractional
share of Acquiror Common Stock shall be issued, and, in lieu thereof, a cash
payment shall be made pursuant to Section 2.02(e) of this Agreement.

     (d) Each share of Company Common Stock held in the treasury of the Company
and each share of Company Common Stock owned by any direct or indirect wholly
owned Subsidiary of the Company immediately prior to the Effective Time shall be
canceled and extinguished without any conversion of such shares and no payment
shall be made with respect to such shares.

     (e) Each share of common stock, par value $0.01 per share, of Acquiror Sub
("Acquiror Sub Common Stock") issued and outstanding immediately prior to the
Effective Time shall remain issued and outstanding after the Merger.

     SECTION 2.02  Exchange of Certificates.

     (a) Exchange Agent. As of the Effective Time, Acquiror shall deposit, or
shall cause to be deposited, with a bank or trust company designated by Acquiror
and acceptable to the Company (the "Exchange Agent"), for the benefit of the
holders of shares of Company Common Stock, for exchange in accordance with this
Article II, through the Exchange Agent, certificates representing the shares of
Acquiror Common Stock (such certificates for shares of Acquiror Common Stock,
together with any dividends or distributions with respect thereto and
appropriate cash payments in lieu of fractional shares of Acquiror Common Stock
pursuant to Section 2.02(e), being referred to as the "Exchange Fund") issuable
at the Closing

                                      A-6
<PAGE>
 
pursuant to Section 2.01(a)(i) (the "Closing Shares") in exchange for
outstanding shares of Company Common Stock. The Exchange Agent shall, pursuant
to irrevocable instructions, deliver the Closing Shares contemplated to be
issued pursuant to Section 2.01 out of the Exchange Fund. The Exchange Fund
shall not be used for any other purpose.

     (b) Exchange Procedures. Promptly after the Effective Time, Acquiror shall
instruct the Exchange Agent to mail to each holder of record of a certificate or
certificates which immediately prior to the Effective Time represented
outstanding shares of Company Common Stock (the "Certificates") (i) a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon proper delivery of the
Certificates to the Exchange Agent and shall be in customary form) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for certificates representing Closing Shares. Upon surrender of a Certificate
for cancellation to the Exchange Agent, together with such letter of transmittal
and a waiver in the form of Exhibit 2.02(b) to this Agreement, each duly
executed, and such other documents as may be required pursuant to such
instructions, the holder of such Certificate shall receive in exchange a
certificate representing that number of whole Closing Shares which such holder
has received in the Merger in respect of the shares of Company Common Stock
formerly represented by such Certificate, cash in lieu of fractional shares of
Acquiror Common Stock to which such holder is entitled pursuant to Section
2.02(e) (after taking into account all shares of Company Common Stock then held
by such holder) and any dividends or other distributions to which such holder is
entitled pursuant to Section 2.02(c) with respect only to the number of whole
shares of Acquiror Common Stock which such holder has received, and the
Certificate so surrendered shall forthwith be canceled. In the event of a
transfer of ownership of shares of Company Common Stock which is not registered
in the transfer records of the Company, a certificate representing the proper
number of shares of Acquiror Common Stock, together with cash in lieu of
fractional shares of Acquiror Common Stock and any dividends or other
distributions to which such holder is entitled, may be issued to such a
transferee if the Certificate representing such shares of Company Common Stock
is presented to the Exchange Agent, accompanied by all documents required to
evidence and effect such transfer and by evidence that any applicable stock
transfer taxes have been paid. Until surrendered as contemplated by this Section
2.02, each Certificate shall be deemed at any time after the Effective Time to
represent solely the right to receive (i) the Merger Consideration and (ii) any
dividends or other distributions to which such holder is entitled pursuant to
Section 2.02(c).

     (c) Distributions with Respect to Unexchanged Shares of Acquiror Common
Stock. No dividends or other distributions declared or made with respect to
Acquiror Common Stock with a record date after the Effective Time shall be paid
to the holder of any unsurrendered Certificate with respect to the shares of
Acquiror Common Stock represented thereby, and no cash payment in lieu of
fractional shares shall be paid to any such holder pursuant to Section 2.02(e),
until the holder

                                      A-7
<PAGE>
 
of such Certificate shall surrender such Certificate. The Surviving Corporation
will replace lost certificates representing Company Common Stock upon receipt of
such documentation as is customary in the case of lost certificates and
reasonably requested by Acquiror. Subject to the effect of escheat, tax or other
applicable Laws, following surrender of any such Certificate, there shall be
paid to the holder, without interest, (i) promptly, the amount of any cash
payable with respect to a fractional share of Acquiror Common Stock to which
such holder is entitled pursuant to Section 2.02(e) and the amount of dividends
or other distributions with a record date after the Effective Time theretofore
paid with respect to the Closing Shares which the holder received as part of the
Merger Consideration, and (ii) at the appropriate payment date, the amount of
dividends or other distributions, with a record date after the Effective Time
but prior to surrender and a payment date occurring after surrender, payable
with respect to the Closing Shares which the holder received as part of the
Merger Consideration.

     (d) No Further Rights in Company Common Stock. All shares of Acquiror
Common Stock issued upon conversion of the shares of Company Common Stock in
accordance with the terms of this Agreement (including any cash paid pursuant to
Sections 2.02(c) or (e)) shall be deemed to have been issued in full
satisfaction of all rights pertaining to such shares of Company Common Stock,
other than the right to receive payments in respect of the Contingent Payment
Rights in accordance with Section 2.04.

     (e) No Fractional Shares. No certificates or scrip representing fractional
shares of Acquiror Common Stock shall be issued upon the surrender for exchange
of Certificates, and the owner of such fractional share interests will not be
entitled to vote or to any other rights of a shareholder of Acquiror. Each
holder of Certificates who otherwise would be entitled to receive a fractional
share of Acquiror Common Stock shall receive, in lieu of such fractional share
interest, an amount in cash (without interest) determined by multiplying (i) the
closing sale price per share of Acquiror Common Stock as reported on the NYSE on
the business day immediately preceding the Closing Date by (ii) the fractional
share interest to which such holder would otherwise be entitled. Acquiror shall
transfer to the Exchange Agent on a timely basis the cash necessary to make
payments under this Section 2.02(e). As soon as practicable after the
determination of the amount of cash, if any, to be paid to holders of Company
Common Stock with respect to any fractional share interests, the Exchange Agent
shall promptly pay such amounts to such holders of Company Common Stock subject
to and in accordance with the terms of Section 2.02(c).

     (f) Termination of Exchange Fund . Any portion of the Exchange Fund which
remains undistributed to the holders of Company Common Stock for one year after
the Effective Time shall be delivered to Acquiror, upon demand, and any holders
of Company Common Stock who have not theretofore complied with this Article II
shall thereafter look only to Acquiror for the shares of Acquiror Common Stock,
any cash in lieu of fractional shares of Acquiror Common Stock to

                                      A-8
<PAGE>
 
which they are entitled pursuant to Section 2.02(e) and any dividends or other
distributions with respect to Acquiror Common Stock to which they are entitled
pursuant to Section 2.02(c).

     (g) No Liability. Neither Acquiror nor the Company shall be liable to any
holder of shares of Company Common Stock for any such shares of Acquiror Common
Stock (or dividends or distributions with respect to such shares) or cash
delivered to a public official pursuant to any abandoned property, escheat,
interpleader or similar Law, provided that Acquiror will endeavor to give the
record holder advance notice thereof at holder's address of record.

     SECTION 2.03  Stock Transfer Books. At the Effective Time, the stock
transfer books of the Company shall be closed and there shall be no further
registration of transfers of shares of Company Common Stock thereafter on the
records of the Company, except for transfers resulting from proceedings under
any interpleader or similar Law. From and after the Effective Time, the holders
of certificates representing shares of Company Common Stock outstanding
immediately prior to the Effective Time shall cease to have any rights with
respect to such shares of Company Common Stock except as otherwise provided in
this Agreement or by Law. On or after the Effective Time, any Certificates
presented to the Exchange Agent or Acquiror, in accordance with Section 2.02(b),
for any reason shall be converted into shares of Acquiror Common Stock, any cash
in lieu of fractional shares of Acquiror Common Stock to which the holders of
the Certificates are entitled pursuant to Section 2.02(e), any dividends or
other distributions to which the holders of the Certificates are entitled
pursuant to Section 2.02(c) and Contingent Payment Rights.

     SECTION 2.04  Contingent Payment Rights.

     (a) Each Contingent Payment Right shall represent only a right to receive a
cash payment (the "Earn-Out") from Acquiror, subject to the terms set forth in
this Section 2.04 and Acquiror's right of offset under Article IX of this
Agreement. The amount of any Earn-Out payment payable with respect to each
Contingent Payment Right shall be equal to the aggregate Earn-Out payment
payable, calculated as set forth below, divided by the total number of
Contingent Payment Rights outstanding as of the date such payment is due. The
amount of the Earn-Out payment payable for each Earn-Out Year (as defined
below), if any, shall be calculated by Acquiror as set forth in this Section
2.04 and paid not later than 45 days following public announcement of Acquiror's
audited financial results for each Earn-Out Year. Contingent Payment Rights
shall not possess any attributes of common stock or other security and shall not
entitle the holders of the Contingent Payment Rights to any rights of any kind
other than as specifically set forth in this Agreement. Subject to Section
2.04(j), all payments of the Earn-Out shall be made net of any amount for which
Acquiror is entitled to indemnification under Article IX of this Agreement.

                                      A-9
<PAGE>
 
     (b) The term "Earn-Out Year" shall refer to each of the following twelve
month periods: (i) January 1, 1996 to December 31, 1996; and (ii) January 1,
1997 to December 31, 1997.

     (c) The Earn-Out payments shall be determined by measuring the Actual Net
Income (as defined below) of the Community Health Entities for Earn-Out Years
1996 and 1997 against certain target amounts, as follows:

          (i) subject to Section 2.04(d) below, for the 1996 Earn-Out Year, the
     total Earn-Out payment shall equal the product of: (A) Actual Net Income
     for the 1996 Earn-Out Year less $10.0 million, multiplied by (B) 6.3;
     provided that if Actual Net Income for the 1996 Earn-Out Year is less than
     $10.0 million, the Earn-Out payment for such year will be zero; and

          (ii) subject to Section 2.04(d) below, for the 1997 Earn-Out Year, the
     total Earn-Out payment shall equal the product of (A) Actual Net Income for
     the 1997 Earn-Out Year less $16.5 million, multiplied by (B) 4.5; provided
     that if Actual Net Income for the 1997 Earn-Out Year is less than $16.5
     million, the Earn-Out payment for such year will be zero.

     (d) In no event shall the aggregate Earn-Out payments payable in respect of
Contingent Payment Rights exceed $35.0 million.  Accordingly, the Earn-Out
payments calculated under Section 2.04(c) above shall be reduced to the extent,
if any, that the sum of such payments exceeds $35.0 million.

     (e) "Actual Net Income" means the audited net income of the Community
Health Entities, determined on a consolidated basis in accordance with GAAP,
subject to the adjustments described in Exhibit 2.04(e). Actual Net Income shall
be determined by Acquiror in the manner set forth in Exhibit 2.04(e) to this
Agreement.

     (f) The Contingent Payment Rights are personal to each initial holder
thereof and shall not be transferable for any reason other than by operation of
law or by will or the laws of descent and distribution. Any attempted transfer
of a Contingent Payment Right by any holder thereof (other than as permitted by
the immediately preceding sentence) shall be null and void.

     (g) Payment of the Earn-Out shall be made by cashier's or certified check.

     (h) During the two Earn-Out Years: (i) Acquiror and the Surviving
Corporation will not dispose of all or substantially all its interest in the
Community Health Entities or otherwise combine the operations of the Community
Health Entities unless Acquiror shall have made reasonably adequate provision to
provide for the determination of the Earn-Out payments; and (ii) Acquiror and
the

                                      A-10
<PAGE>
 
Surviving Corporation will maintain its books and records in accordance with
GAAP.

     (i) Within 90 days following the end of each Earn-Out Year, Acquiror will
deliver to the Shareholder Representative, as defined in Section 2.04(k), a
calculation of the aggregate Earn-Out with respect to such Year, together with
the certification of the chief financial officers of Acquiror and the Surviving
Corporation to the effect that the provisions of Section 2.04(h) have been
complied with, and the further certification of such officers and the
independent certified public accountants of Acquiror or the Surviving
Corporation to the effect that the calculation shown therein is in accordance
with an audit by such accountants of the Community Health Entities, with the
adjustments provided for in Exhibit 2.04(e). A copy of the audit shall be
delivered to the Shareholder Representative, together with such other
information reasonably related to the calculation of the Earn-out as the
Shareholder Representative may reasonably request. The Shareholder
Representative will be deemed to have accepted such calculation and to have
waived forever any right to contest it unless it notifies Acquiror within 60
days after delivery of the calculation to the Shareholder Representative that
such Representative contests such calculation and the reasons therefor. Any such
contest which cannot be resolved within 30 days by Acquiror and the Shareholder
Representative shall be resolved by arbitration in the manner provided in
Section 11.01, except that the third arbitrator shall be a member of a
nationally recognized accounting firm. Acquiror shall make the Earn-Out payment
required pursuant to Section 2.04(a) when due notwithstanding the pendency of
any such contest, except that until such contest shall have been finally
determined Acquiror shall be required to pay only the amount reflected in its
calculation. Any remaining amount determined to be due by the arbitrators, or
any other amount not paid by the due date, shall bear interest at the rate
provided for in Section 9.05 from the original due date until paid.

     (j) If, at the time an Earn-Out payment is otherwise to be made, Acquiror
reasonably determines that it is or may be entitled to an offset pursuant to
Article IX against such payment, Acquiror shall, in good faith, estimate the
amount of such offset and deduct it from the payments otherwise to be made
pursuant to this Section 2.04. Acquiror shall give prompt notice of any such
offset to the Shareholder Representative (as defined in Section 2.04(k)).
Promptly following any development that would reduce the amount of such offset,
Acquiror shall remit to the Former Holders (as defined in Section 2.04(k)) the
resulting amount in the manner provided for in this Section 2.04 together with
interest as provided in Section 9.05.

     (k) (i) A group of 3 shareholders of the Company (the "Shareholder
Representative") shall be constituted to act on behalf of the persons who were
shareholders of the Company at the Effective Time ("Former Holders") with
respect to all matters relating to Earn-Out payments pursuant to this Section
2.04 as well as to any indemnity pursuant to Article IX. The Shareholder
Representative shall

                                      A-11
<PAGE>
 
consist initially of the persons identified in Exhibit 2.04(k). The Shareholder
Representative shall act (A) by meeting (of which reasonable notice shall be
given to its members of the date, time, place, and purpose, which notice may be
waived in writing but shall not otherwise be deemed to have been waived), by the
affirmative vote of at least a majority of the persons serving as Shareholder
Representative (failing which the Shareholder Representative shall be deemed to
have determined not to act with respect to the matter voted upon), which vote
may be cast by general or special proxy held by any Former Holder, or (B) by
unanimous written consent. Any vacancy in the Shareholder Representative may be
filled by majority vote of the remaining persons then serving (even if not
constituting a quorum) from among Former Holders.

     (ii) The Former Holders may at any time, by vote of a majority of their
former voting power of Company Common Stock present in person or by proxy at a
meeting or by written consent of such a majority, (A) remove any person from
service as a member of the Shareholder Representative and elect a replacement
(who shall be a Former Holder) and (B) ratify any proposed action of the
Shareholder Representative. No such ratification shall be required unless so
determined by the Shareholder Representative.

     (iii) Meetings of the Former Holders shall be held as if the Company were
still in existence, still had the same Articles and By-Laws as it had at the
Effective Time, the Former Holders were its holders of record, and the persons
serving as Shareholder Representative were its directors. The Shareholder
Representative will not be liable for any act or failure to act in the capacity
as Shareholder Representative except to the extent such act or failure to act
involved gross negligence or wilful misconduct. Any action taken in good faith
upon the written advice of qualified legal counsel or certified public
accountants shall be conclusively deemed not to constitute gross negligence or
wilful misconduct. The Surviving Corporation and Acquiror shall, promptly upon
request, pay the reasonable expenses of the Shareholder Representative with
respect to its duties hereunder, including the fees of counsel and accountants,
up to a maximum aggregate amount of $200,000. In addition, upon request by
notice at any time from the Shareholder Representative, Acquiror will pay
directly to the Shareholder Representative such portion of any subsequent Earn-
Out payment as the Shareholder Representative may request for the purpose of
paying expenses incurred or reasonably anticipated by the Shareholder
Representative.

     (iv) The Shareholder Representative may pay, from any funds held by it, any
expenses incurred by it in such capacity and may reimburse its members for their
reasonable expenses and indemnify them against claims made against them as
persons serving as Shareholder Representative to the same extent as if funds
held by the Shareholder Representative were funds of the Company and the persons
serving as Shareholder Representative were directors of the Company.

     SECTION 2.05  Dissenting Shareholders. In the event the Merger is approved 
by less than 80% of the total voting power of the outstanding Company Common
Stock, each outstanding share of Company Common Stock, the holder of which has
demanded and perfected such shareholder's demand for payment of the fair value
of such share in accordance with Section 12:131 of the Louisiana Law (the
"Dissent Provisions"), to the extent applicable, and has not effectively
withdrawn or lost such shareholder's right to an appraisal (the "Dissenting
Shares"), shall not be converted into or represent a right to receive the Merger
Consideration issuable or payable in the Merger but the holder thereof shall be
entitled only to such rights as are granted by the Dissent Provisions. In the
event the Merger is approved by less than 80% of the total voting power of the
outstanding Company Common Stock, the Company shall give Acquiror prompt written
notice upon receipt by the Company of any written objection to the Merger and
any written demands for payment of the fair cash value of shares of Company
Common Stock, and of withdrawals of such demands, and any other instruments
provided to the Company pursuant to the Dissent Provisions (any shareholder duly
making such demand being hereinafter called a "Dissenting Shareholder"). Each
Dissenting Shareholder who becomes entitled, pursuant to the Dissent Provisions,
to payment of the fair cash value for any shares of Company Common Stock held by
such Dissenting Shareholder shall receive payment therefor from the Surviving
Corporation (but only after the amount thereof shall have been agreed upon or at
the times and in the amounts required by the Dissent Provisions) and all of such
Dissenting Shareholder's shares of Company Common Stock shall be canceled.
Neither the Company nor the Surviving Corporation shall, except with the prior
written consent of Acquiror, voluntarily make any payment with respect to, or
settle or offer to settle, any demand for payment by any Dissenting Shareholder.
If any Dissenting Shareholder shall have failed to perfect or shall have
effectively withdrawn or lost such right to demand payment of the fair cash
value, the shares of Company Common Stock held by such Dissenting Shareholder
shall thereupon be deemed to have converted into the right to receive the
consideration to be issued in the Merger as provided by this Agreement.


                                  ARTICLE III
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     Except as set forth in the Disclosure Schedule delivered by the Company to
Acquiror prior to the execution of this Agreement (the "Company Disclosure
Schedule"), which identifies exceptions by specific Section references, the
Company hereby represents and warrants to Acquiror as set forth in this Article
III. For purposes of this Article III, references to the "Company" mean solely
Louisiana Independent Physicians Association, Inc. and exclude all Community
Health Entities as well as any obligation or liability of the Company that
exists solely by reason of its status as a partner or shareholder, as the case
may be, of any of the Community Health Entities or as a consolidated parent of
any of them. All representations and warranties that pertain to the Community
Health Entities

                                      A-13
<PAGE>
 
(including, without limitation, representations and warranties pertaining to the
Company Financial Statements (as defined in Section 3.07(b)), to the extent such
Financial Statements include the accounts of any of the Community Health
Entities) are based on the Company's actual knowledge, without independent
investigation or inquiry.

     SECTION 3.01  Organization and Qualification; Subsidiaries. The Company is 
a corporation, duly incorporated, validly existing and in good standing under
the Laws of the jurisdiction of its incorporation or organization, has all
requisite corporate power and authority to own, lease and operate its properties
and to carry on its business as it is now being conducted and is duly qualified
and in good standing to do business in each jurisdiction in which the nature of
the business conducted by it or the ownership or leasing of its properties makes
such qualification necessary. Except for CHN, 51% of the outstanding common
stock of which is owned by the Company, the Company does not have any
Subsidiaries.

     SECTION 3.02 Articles of Incorporation; By-Laws. The Company has furnished
to Acquiror complete and correct copies of the Articles of Incorporation and the
By-Laws, as amended or restated, of the Company. The Company is not in violation
of any of the provisions of its Articles of Incorporation or By-Laws.

     SECTION 3.03  Capitalization; Ownership of Shares.

     (a) As of the date of this Agreement, the authorized capital stock of the
Company consists of 5,000 shares of Company Common Stock, of which 418 shares
were issued and outstanding.

     (b) Of the shares of CHN common stock outstanding, 900,000 are held
beneficially and of record by the Company. Of the shares of common stock of LHP
outstanding, 490 are held beneficially and of record by the Company.
Information, as of the date of this Agreement, relating to the Company's
beneficial and record ownership of outstanding partnership interests in LHMC, is
set forth in the Company Disclosure Schedule.

     (c) Except as described in this Section 3.03, no shares of Company Common
Stock are reserved for any purpose. Since December 31, 1994, no shares of
Company Common Stock have been issued by the Company. Each of the outstanding
shares of Company Common Stock is duly authorized, validly issued, fully paid
and non-assessable, and such shares were issued in compliance with all
applicable federal and state securities Laws. None of the outstanding shares of
Company Common Stock are subject to preemptive rights created by statute, the
Company's Articles of Incorporation or By-Laws or any agreement to which the
Company is a party or by which it is bound. Section 3.03 of the Company
Disclosure Schedule sets forth a true and complete list of the shareholders of
record of the Company, including the name, address and number of shares held by
each such shareholder.

     SECTION 3.07  Reports; Financial Statements.

     (a) Since December 31, 1991, the Company has filed all forms, reports
statements and other documents required to be filed by it with (i) the SEC, (ii)
any applicable state securities authorities; and (iii) any other applicable

insurance and health regulatory authorities (all such forms, reports, statements
and other documents being collectively referred to as the "Company Reports").
The Company Reports, including all Company Reports filed after the date of this
Agreement and prior to the Effective Time were or will be prepared in all
material respects in accordance with the requirements of applicable Law.

     (b) The Company has reviewed copies of (i) the consolidated balance sheet
of the Company as at December 31, 1994 and the related consolidated statements
of operations, shareholders' equity and cash flows for the fiscal year then
ended together with any notes thereto audited by Arthur Andersen LLP (the "1994
Financials"), (ii) the unaudited balance sheets of the Company as at September
30, 1995 and the related unaudited statement of operations for the nine months
then ended (the "1995 Financials"), (iii) the respective balance sheets of CHN,
LHP and LHMC, as at December 31, 1994 and the respective related statements of
operations, and cash flows for the fiscal year then ended together with any
notes thereto, audited by Arthur Andersen LLP, (the "1994 Louisiana

<PAGE>
 
Financials are sometimes collectively referred to herein as the "Louisiana
Financial Statements." Copies of the Company Financial Statements have been
delivered to Acquiror. Those portions of the Company Financial Statements
relating directly to the Company on an unconsolidated basis present fairly in
accordance with GAAP the financial position of the Company as of the respective
date thereof and the results of operations and cash flows for the periods
indicated, except that such Company Financial Statements are not consolidated
with the majority owned subsidiary, do not include a statement of cash flows,
and omit substantially all disclosures. The 1995 Financials and Louisiana
Financials are subject to normal and recurring year-end adjustments and
consolidation. To the Company's knowledge, the Louisiana Financial Statements
(including, in each case, any related notes to such statements, if any) do not
contain any material inaccuracy that would cause such financial statements not
to present fairly in accordance with GAAP, in all material respects, the
financial position of CHN, LHP and LHMC, as the case may be, as of the
respective dates thereof and the results of operations and cash flows of each
such entity for the periods indicated, except that the 1995 Louisiana Financial
Statements are subject to normal and recurring year-end adjustments which, to
the Company's knowledge, are not expected to be material in amount and do not
have statements of cash flows and accompanying footnotes.

     (c) The Company does not actively conduct, and has not ever actively
conducted, any trade or business, except indirectly through the Community Health

to the extent set forth on the Company Financial Statements, including all notes
thereto, the Company does not have any material liabilities or obligations of
any nature (whether known or unknown, matured or unmatured, and whether accrued,
absolute, contingent or otherwise) that would be required to be reflected on, or
reserved against in, a balance sheet of the Company or in the notes thereto
prepared in accordance with GAAP, other than those incurred in the ordinary
course of business since September 30, 1995 that would not have a Community
Health Material Adverse Effect and none of which is a liability resulting from
breach of contract, breach of warrant, tort, infringement, claim or lawsuit and
except for those incurred in connection with this Agreement and the transactions
contemplated hereby, none of which would constitute a Community Health Material
Adverse Effect.

     SECTION 3.08  Absence of Certain Changes or Events.  Except as

Entity or arbitrator, including, without limitation, cease-and-desist or other

(collectively, the "Indemnitees") against all losses, expenses (including
reasonable attorney's fees), claims, damages, liabilities, costs or judgments or
amounts that are paid in settlement with the written consent of Acquiror arising
out of actions or omissions occurring at or prior to the Effective Time in the
Indemnitees' respective capacities as officers and/or directors of the Company
and/or any of the Community Health Entities (including the transactions
contemplated by this Agreement but excluding claims against an Indemnitee
relating to that Indemnitee's purchase of Company Common Stock from another
shareholder of the Company) to the full extent permitted as of the date of this
Agreement by the Louisiana Law or the Company's Articles of Incorporation and
Bylaws (and shall also advance expenses as incurred to the fullest extent
permitted under the Louisiana Law or the Company's Articles of Incorporation and
Bylaws; provided that the person to whom expenses are advanced provides an
undertaking to repay such advances as contemplated by applicable Law or such
Articles of Incorporation or Bylaws). The Company shall use reasonable efforts
to obtain extended reporting endorsements (tail coverage) on the fiduciary
liability, professional liability and directors and officers liability policies
currently covering the Company or any of the Indemnitees required to be
indemnified by Acquiror at a commercially reasonable cost, effective as of and
following the Closing; provided that such coverage and the cost thereof shall be
subject to Acquiror's approval. In connection with such efforts, the Company
will use its reasonable efforts to accurately complete any insurance
applications and forms of the applicable insurer and take any reasonable steps
to preserve any known claims, including submitting a full and complete list of
any potential claims of which the Company has knowledge, under the policy issued
by such insurer. In the event the Company is unable to obtain such extended
reporting coverage under the Company's existing directors and officers liability
insurance policies at a commercially reasonable cost, Acquiror shall use
reasonable efforts to provide similar coverage for those Indemnitees that it is
required to indemnify under policies then maintained by Acquiror; provided that
such similar coverage is available to Acquiror at a commercially reasonable
cost. Notwithstanding any provisions of this Section 6.06(a), failure by the
Company, Acquiror, or both, despite

                                      A-36
<PAGE>
 
use of their respective reasonable efforts, to obtain such extended reporting
endorsements or to provide such similar coverage under Acquiror's policies shall
not in any way affect, lessen or excuse Acquiror from its obligation to, and to
cause the Surviving Corporation to, indemnify, defend and hold harmless the
Indemnitees to the extent required by this Section 6.06.

     (b) In the event any claim, action, suit, proceeding or investigation (a
"D&O Claim") for which indemnification is provided under this Section 6.06 is
brought against an Indemnitee (whether arising before or after the Closing)
after the Closing (i) such Indemnitee may retain counsel satisfactory to it
(subject to prior reasonable approval by Acquiror and subject to the terms and
conditions of the applicable directors and officers liability insurance or
fiduciary liability insurance policies), (ii) the indemnifying party shall pay
all reasonable fees and expenses of such counsel for such Indemnitee promptly as
statements therefor are received (subject to the ability of the indemnifying
party to receive such information relative to the legal services provided as is
customarily provided and reasonably requested by the indemnifying party and
provided that nothing in this Section 6.06 shall prevent the indemnifying party
from disputing any fees it believes are not reasonable), and (iii) the
indemnifying party will use all reasonable efforts to assist in the vigorous
defense of any such matter, provided that the indemnifying party shall not be
liable for any settlement of any D&O Claim effected without its written consent,
which consent will not be unreasonably withheld. Any Indemnitee wishing to claim
indemnification under this Section 6.06, upon learning of any such D&O Claim,
shall notify the appropriate indemnifying party (but the failure so to notify
such indemnifying party shall not relieve it from any liability which it may
have under this Section 6.06 except to the extent such failure materially
prejudices such indemnifying party), and shall deliver to such indemnifying
party the expense reimbursement undertaking contemplated by applicable Law. The
Indemnitees as a group may retain only one law firm to represent them with
respect to each such matter unless there is, under applicable standards of
professional conduct, a conflict on any significant issue between the positions
of any two or more Indemnitees.

     (c) This Section 6.06 is intended to benefit the Indemnitees, shall be
enforceable by each Indemnitee and his or her heirs and representatives, and
shall be binding on all successors and assigns of the Company and Acquiror.

     SECTION 6.07  Obligations of Acquiror Sub. Acquiror shall take all action 
necessary to cause Acquiror Sub to perform its obligations under this Agreement
and to consummate the Merger on the terms and conditions set forth in this
Agreement.

     SECTION 6.08  Registration of Acquiror Common Stock.

     (a) As promptly as practicable after the execution of this Agreement,
Acquiror shall prepare and file with the SEC a registration statement on Form 
S-4 (the registration statement together with the amendments thereto being the

                                      A-37
<PAGE>
 
"Registration Statement"), complying in all material respects with the
applicable requirements of the Securities Act and Exchange Act, in connection
with the registration under the Securities Act of the Acquiror Common Stock
issuable in the Merger. As promptly as practicable after the execution of this
Agreement, the Company shall cause to be prepared those portions of the proxy
statement/prospectus contained in the Registration Statement that pertain
directly to the Company, and a form of proxy, in connection with the vote of the
Company's shareholders with respect to the Merger (such proxy
statement/prospectus, together with any amendments thereof or supplements
thereto, in each case in the form or forms mailed to the Company's shareholders,
being the "Proxy Statement"). The form of proxy included in the Proxy Statement
shall include or be accompanied by a waiver substantially in the form of Exhibit
2.02(b) to this Agreement. Each of Acquiror and the Company will use all
reasonable efforts to cause the Registration Statement to become effective as
promptly as practicable, which Registration Statement, at the time it becomes
effective, and at the Effective Time, shall in all material respects conform to
the requirements of the Securities Act. Acquiror shall take all actions required
to register or qualify or obtain exemptions from such registrations or
qualifications under any applicable state securities laws in connection with the
issuance of shares of Acquiror Common Stock in the Merger. Each of Acquiror and
the Company shall furnish all information concerning it and the holders of its
capital stock as the other may reasonably request in connection with such
actions. As promptly as practicable after the Registration Statement shall have
become effective, the Company shall mail the Proxy Statement to its
shareholders. The Proxy Statement shall include the recommendation of the
Company's Board of Directors in favor of the Merger unless, in the written
opinion of counsel experienced in such matters, the inclusion of such
recommendation would constitute a breach of such directors' fiduciary duties.

     (b) The Company covenants and agrees that the information specifically
designated as being supplied by the Company for inclusion in the Registration
Statement shall not, at the time the Registration Statement is declared
effective, contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they are made, not
misleading. The Company covenants and agrees that the information specifically
designated as being supplied by the Company for inclusion in the Proxy Statement
to be sent to the shareholders of the Company in connection with the meeting of
the Company's shareholders to consider the Merger (the "Shareholder Meeting")
shall not, at the date the Proxy Statement (or any amendment thereof or
supplement thereto) is first mailed to shareholders, or at the time of the
Shareholder Meeting, contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they
are made, not misleading. If at any time prior to the Effective Time the Company
discovers any event or circumstance relating to the Company, or its officers or
directors, which should be set forth in an

                                      A-38
<PAGE>
 
amendment to the Registration Statement or a supplement to the Proxy Statement,
the Company shall promptly inform Acquiror of such event or circumstance.

     (c) The Acquiror covenants and agrees that, except for the information
referred to in subsection (b) above, the Registration Statement shall not, at
the time the Registration Statement is declared effective, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they are made, not misleading. The Acquiror
covenants and agrees that, except for the information referred to in subsection
(b) above, in the Proxy Statement to be sent to the shareholders of the Company
in connection with the Shareholder Meeting shall not, at the date the Proxy
Statement (or any amendment thereof or supplement thereto) is first mailed to
shareholders, or at the time of the Shareholder Meeting, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they are made, not misleading. If at any
time prior to the Effective Time Acquiror discovers any event or circumstance
relating to Acquiror or any of its Subsidiaries, or its or their respective
officers or directors which should be set forth in an amendment to the
Registration Statement or a supplement to the Proxy Statement, Acquiror shall
promptly inform the Company of such event or circumstance and shall promptly
file such amendment to the Registration Statement or supplement to the Proxy
Statement. All documents that Acquiror is responsible for filing with the SEC in
connection with the transactions contemplated herein will comply as to form and
substance in all material respects with the applicable requirements of the
Securities Act and the Exchange Act.

     (d) Each party to the Agreement hereby (i) consents to the use of its name
and, on behalf of its Subsidiaries and affiliates, the names of such
Subsidiaries and affiliates and to the inclusion of financial statements and
business information relating to such party and its Subsidiaries and affiliates
(in each case, to the extent required by applicable securities laws) in any
registration statement or proxy statement prepared by the Company, Acquiror or
any person or entity with which the Acquiror may enter into a definitive
acquisition agreement prior to the Effective Time, (ii) agrees to use its
reasonable efforts to obtain the written consent of any person or entity
retained by it which may be required to be named (as an expert or otherwise) in
such registration statement or proxy statement (provided that reasonable
efforts, as used herein and elsewhere in this Agreement, shall not include
expending money other than as is customary for professional advisors and
reasonable expenses) and (iii) agrees to cooperate, and agrees to use its
reasonable efforts to cause its Subsidiaries and affiliates to cooperate, with
any legal counsel, investment banker, accountant or other agent or
representative retained by any of the parties specified in clause (i) in
connection with the preparation of any and all information required, as
determined after consultation with each party's counsel, by applicable
securities laws to be disclosed in any such registration statement or proxy
statement.

                                      A-39

     (e) The Company shall use its reasonable efforts to cause to be delivered
to Acquiror "cold comfort" letters of Arthur Andersen LLP, its independent
public accountant, dated the date on which the Registration Statement shall
become effective and as of the Closing, respectively, and addressed to Acquiror,
in form and substance reasonably satisfactory to Acquiror and reasonably
customary in scope and substance for letters delivered by independent public
accountants in connection with registration statements similar to the
Registration Statement and transactions such as those contemplated by this
Agreement.

     (f) Acquiror shall use its reasonable efforts to cause to be delivered to
the Company "cold comfort" letters of Arthur Andersen LLP, its independent
public accountant, dated the date on which the Registration Statement shall
become effective and as of the Closing, respectively, and addressed to the
Company, in form and substance reasonably satisfactory to the Company and
reasonably customary in scope and substance for letters delivered by independent
public accountants in connection with registration statements similar to the
Registration Statement and transactions such as those contemplated by this
Agreement.

     (g) Acquiror will indemnify and hold harmless the Company, and each of its
directors and officers, and each controlling person of the Company within the
meaning of the Securities Act, against any claims, suits, proceedings,
investigations or other actions ("Claims"), and any related losses, damages,
costs, expenses, liabilities or judgments, whether joint, several or solidary
insofar as they arise out of or are based upon an untrue statement or alleged
untrue statement of a material fact made in the Registration Statement or the
Proxy Statement, or an omission or alleged omission therefrom of a material fact
necessary in order to make the statements made therein, in light of the
circumstances under which they were made, not misleading, and will reimburse
each such person promptly as incurred for legal and other expenses reasonably
incurred in connection with investigating or defending any such Claims;
provided, that Acquiror will not be liable to the extent that any such Claim
arises out of or is based upon any such untrue statement or omission or alleged
untrue statement or omission made in reliance on and in conformity with
information furnished to Acquiror by the Company or, with respect to any other
indemnified person, by that person, specifically for inclusion therein.

     (h) Any indemnified person wishing to claim indemnification under Section
6.08(g), upon learning of any claim, shall notify Acquiror thereof as promptly
as is practicable, but the failure so to notify Acquiror shall not relieve
Acquiror from any obligation it has under Section 6.08(g) except to the extent
it is actually prejudiced by such failure. Acquiror shall have the right to
assume the defense thereof and shall not be liable for any expenses subsequently
incurred by such indemnified person in connection with the defense thereof,
except that if Acquiror does not assume or continue to pursue such defense, or
counsel for the indemnified person advises in writing that there are material
substantive issues

                                      A-40
<PAGE>
 
that raise conflicts of interest between Acquiror and the indemnified person,
requiring separate representation under applicable attorneys' rules of
professional conduct, then the indemnified person may retain counsel
satisfactory to such person (and reasonably satisfactory to Acquiror), and
Acquiror shall pay all reasonable fees and expenses of such counsel promptly as
incurred, provided that (i) Acquiror shall not be obligated to pay for more than
one counsel for all indemnified persons in any jurisdiction except as may be
required due to conflicts of interest as evidenced by a written opinion of
reputable counsel, (ii) the indemnified persons will cooperate (to the extent
reasonably appropriate under the circumstances) in the defense of any such
claim, and (iii) Acquiror shall not be liable for any settlement effected
without its prior written consent.

     SECTION 6.09  Cooperation and Exchange of Tax Information; Preparation of 
Tax Returns.

     (a) The Company shall file (or cause to be filed) at its own expense, on or
prior to the due date, all Tax returns for all Tax periods ending on or before
the Closing Date where the due date for such returns or reports (taking into
account valid extensions of the respective due dates) falls on or before the
Closing Date; provided, however, that the Company shall not file any such Tax
returns, or other returns, elections, claims for refund or information
statements with respect to any liabilities for Taxes (other than federal, state
or local sales, use, withholding or employment tax returns or statements) for
any Tax period, or consent to any adjustment or otherwise compromise or settle
any matters with respect to Taxes, without prior consultation with Acquiror;
provided, further, that the Company shall not make any election or take any
other discretionary position with respect to Taxes, in a manner inconsistent
with past practices, without the prior written approval of Acquiror. The Company
shall provide Acquiror with a copy of appropriate workpapers, schedules, drafts
and final copies of each federal and state income Tax return or election of the
Company (including returns of all Employee Benefit Plans) at least ten days
before filing such return or election and shall reasonably cooperate with any
request by Acquiror in connection therewith.

     (b) Acquiror will file (or cause to be filed) all Tax returns of the
Company due after the Closing Date. After the Closing Date, Acquiror, to the
extent permitted by Law, shall have the right to amend, modify or otherwise
change all Tax returns of the Company for all Tax Periods. Acquiror will file
(or cause to be filed) any Returns of the Company for Tax periods which begin
before the Closing Date and end after the Closing Date. All such Returns
described in this Section 6.09(b) and any schedules to be included therewith
shall be prepared on a basis consistent with those of the Company prepared for
prior Tax periods.

     (c) For purposes of this Section 6.09, all references to the Company shall
include the Subsidiaries and affiliates, and the former Subsidiaries and
affiliates, of the Company.

     SECTION 6.10  NYSE Listing. Acquiror shall cause those shares of Acquiror 
Common Stock to be issued in the Merger to be listed on the NYSE, subject only 
to official notice of issuance thereof.

     SECTION 6.11  Other Agreements.

     (a) The Company will use reasonable efforts to cause each director and
officer of the Company to encourage actively all other Company shareholders to
vote their shares in favor of the Merger, unless to do so in the written opinion
of counsel experienced in such matters would violate such directors' fiduciary
duties; provided that any director of the Company who votes, in such person's
capacity as a director, against approval of the Merger by the Company's board of
directors shall only be required to agree, subject to fiduciary duties, not to
discourage any shareholder of the Company from voting such shareholder's Company
Common Stock in favor of the Merger.

     (b) The Company shall use its reasonable efforts to obtain from each
shareholder of the Company who is also a provider of medical services to the
Company or the Community Health Entities the waiver contemplated by Exhibit
2.02(b).
                                    
     SECTION 6.12  Consulting Agreements. As a material inducement to Acquiror 
to enter into this Agreement and consummate the Merger, and in order to assist
Acquiror in operating the Community Health Entities for a period following the
Closing, Acquiror has required that each of the persons listed on Exhibit 6.12
enter into a consulting and noncompetition agreement with Acquiror, which
agreements shall be executed and delivered by such persons not later than the
Closing.

     SECTION 6.13.  Access to Information. After the Effective Time, Acquiror
shall grant and cause the Surviving Corporation to grant to the Shareholder
Representative (defined in Section 2.04(k)) (or their designees) access at all
reasonable times to information, books and records relating to the Company or
the Surviving Corporation within the possession of Acquiror or the Surviving
Corporation (including workpapers and correspondence with taxing authorities),
and shall afford the Shareholder Representative (or their designees) the right
(at the expense of the Shareholder Representative except to any extent to which
such expense is subject to indemnification under Section 9.07) to take extracts
therefrom and to make copies thereof, but only to the extent necessary to permit
the Shareholder Representative (or their designees) to prepare Tax Returns, to
conduct negotiations with Tax authorities, or to implement the provisions of, or
to investigate or defend any claims between the parties arising under, this
Agreement. Acquiror will, and will cause the Surviving Corporation to, retain
all of the Company's books and records and those of the Surviving Corporation
relating to the Company, for not less than three years following the Effective
Time or such

                                      A-42
<PAGE>
 
longer period of time during which any claim for indemnity or dispute regarding
payments pursuant to Section 2.04 remains unresolved.

     SECTION 6.14.  Rule 145 Transfers. If any holder of Company Common Stock 
(or affiliate or associate thereof) who is subject to Rule 145 under the
Securities Act with respect to shares of Acquiror Common Stock desires to sell,
transfer or otherwise dispose of any of such Acquiror Common Stock during the
restrictive period set forth in Rule 145(d), Acquiror will request its transfer
agent to send a copy of the typical representation letter and other information
to Acquiror's counsel. If Acquiror's counsel concludes that such proposed
disposition complies with Rule 145(d), Acquiror shall request such counsel, at
Acquiror's expense, to provide such opinions as may be necessary to Acquiror's
transfer agent so that such transfer agent may complete the proposed
disposition. If such counsel is unable to so conclude, such counsel will
immediately notify such holder of the reasons and of any action that would
enable such counsel to conclude that such proposed disposition complies with
Rule 145(d).

satisfaction (or waiver by the Company) of each of the following conditions;
provided that, under no circumstances shall the decrease in the price per share

                                   ARTICLE IX
                                INDEMNIFICATION

results of any such investigation and notwithstanding the participation of such
party in the Closing, the representations and warranties contained in Articles

     SECTION 9.02  Indemnification of Acquiror.

     (a) Subject to the limitations set forth in Section 9.02(b) below, Acquiror
and its officers, directors, employees and agents (collectively, the "Acquiror
Indemnified Parties") shall, from and after the Effective Time, be indemnified
and held harmless against any loss, liability, Tax (including interest and
penalties), damage or expense (including reasonable legal expenses and costs) or
any assertion thereof, whether or not matured, contingent or prospective in
nature ("Losses"), which any Acquiror Indemnified Party (but without
duplication) may suffer, sustain or become subject to as a result of (i) any
representation or warranty by the Company in this Agreement, that is not true
and correct as of the date made, other than any such representation and warranty
pertaining to any of the Community Health Entities as to which Acquiror has
actual knowledge no later than the Effective Time that such representation and
warranty is not then or was not when made true and correct, (ii) any breach of
any covenant or agreement of the Company contained in this Agreement, but only
to the extent that such agreement or covenant is required to be performed prior
to the Effective Time, (iii) any claim by a person who held shares of Company
Common Stock prior to the Effective Time against the Company or one or more
directors or officers of the Company alleging a breach of fiduciary duty or
other improper action by such director(s) or officer(s) in connection with the
approval of the Merger, this Agreement and the transactions contemplated hereby,

                                      A-49
<PAGE>
 
(iv) any claim for indemnification under Section 6.06, (v) Taxes, if any, of the
Company, any of its Subsidiaries or Acquiror Sub, or any successor thereto, as a
result of the failure of the Merger to qualify as a tax-free reorganization
under Section 368(a) of the Code by reason of any actions taken by any Former
Holder of the Company after the Effective Time, and (vi) any amounts paid in
respect of Dissenting Shares in excess of the Merger Consideration. Such
indemnification shall be deemed to be a reduction in the Merger Consideration,
shall be payable solely as provided in Section 9.03(c), and shall not constitute
a personal liability of any shareholder of the Company or any officer, director,
employee or agent of the Company.

     (b) The Acquiror Indemnified Parties shall be entitled to indemnification
for any Losses described in Section 9.02(a) only if (i) aggregate Losses for
which timely notice is given in accordance with clause (ii) exceed $1,000,000
(and then the Acquiror Indemnified Parties shall be indemnified only to the
extent of such excess) and (ii) Acquiror or another Acquiror Indemnified Party
delivers to the Shareholder Representative written notice, setting forth in
reasonable detail the basis of the claim and the identity, nature and (to the
extent known) amount of Losses related to such claim or claims prior to
expiration of Acquiror's right to indemnity under Section 9.04. Notwithstanding
the foregoing, the aggregate entitlement of the Acquiror Indemnified Parties for
indemnity under this Article IX shall be payable solely as provided in Section
9.03.

     SECTION 9.03  Method of Asserting Claims. As used in this Section 9.03, the
terms "Indemnified Party" and "Notifying Party" shall refer to the Acquiror
Indemnified Party who is entitled to indemnification hereunder.

     (a) In the event that any of the Indemnified Parties is made a defendant in
or party to any action or proceeding, judicial or administrative, instituted by
any third party, the liability or the costs or expenses of which are Losses (any
such third party action or proceeding being referred to as a "Claim"), the
Notifying Party shall give the Shareholder Representative prompt notice thereof.
The failure to give such notice shall not affect any Indemnified Party's ability
to seek indemnification unless such failure has materially and adversely
affected the Shareholder Representative's ability to defend successfully a
Claim. The Shareholder Representative shall be entitled, on behalf of the
Company's shareholders, to contest and defend such Claim; provided that the
Shareholder Representative (i) has a reasonable basis for concluding that such
defense may be successful and (ii) diligently contests and defends such Claim.
Notice of the intention so to contest and defend shall be given by the
Shareholder Representative to the Notifying Party within 20 business days after
the Notifying Party's notice of such Claim (but, in all events, at least five
business days prior to the date that an answer to such Claim is due to be
filed). Such contest and defense shall be conducted by reputable attorneys
employed by the Shareholder Representative. Acquiror shall pay the reasonable
fees and reimbursable expenses of such attorneys (based on no more than normal
hourly rates for services provided, without markup

                                      A-50
<PAGE>
 
and the actual cost of any such disbursements) promptly as billed and all other
reasonable expenses of conducting such defense, all of which payments shall
constitute Losses. The Notifying Party shall be entitled at any time, at its own
cost and expense (which expense shall not constitute a Loss unless the Notifying
Party reasonably determines that the Shareholder Representative is not
adequately representing or, because of a conflict of interest, may not
adequately represent, any interests of the Indemnified Parties, and only to the
extent that such expenses are reasonable), to participate in such contest and
defense and to be represented by attorneys of its or their own choosing. If the
Notifying Party elects to participate in such defense, the Notifying Party will
cooperate with the Shareholder Representative in the conduct of such defense.
Neither the Notifying Party nor the Shareholder Representative may concede,
settle or compromise any Claim without the consent of the other party, which
consents will not be unreasonably withheld. Notwithstanding the foregoing, (i)
if a Claim seeks equitable relief or (ii) if the subject matter of a Claim
relates to the ongoing business of any of the Indemnified Parties, which Claim,
if decided against any of the Indemnified Parties, would materially adversely
affect the ongoing business or reputation of any of the Indemnified Parties,
then, in each such case, the Indemnified Parties alone shall be entitled to
contest, defend and settle such Claim in the first instance and, if the
Indemnified Parties do not contest, defend or settle such Claim, the Shareholder
Representative shall then have the right to contest and defend (but not settle)
such Claim.

     (b) In the event any Indemnified Party should have a claim for
indemnification under this Article IX that does not involve a Claim, the
Notifying Party shall deliver a notice of such claim with reasonable promptness
to the Shareholder Representative. If the Shareholder Representative notifies
the Notifying Party that it does not dispute the claim described in such notice
or fails to notify the Notifying Party within 30 days after delivery of such
notice by the Notifying Party whether the Shareholder Representative disputes
the claim described in such notice, the Notifying Party shall conclusively be
deemed to be entitled to indemnification for the Loss in the amount specified in
the Notifying Party's notice by offset as provided in Section 9.03(c). If the
Shareholder Representative has timely disputed Liability with respect to such
claim, the representatives of each of the Shareholder Representative and the
Notifying Party will proceed in good faith to negotiate a resolution of such
dispute, and if not resolved through the negotiations of such persons within 60
days after the delivery of the Notifying Party's notice of such claim, such
dispute shall be resolved fully and finally pursuant to an arbitration
proceeding in accordance with Section 11.01 below. The arbitrator(s) shall
resolve the dispute within 30 days after selection, and judgment upon the award
rendered by such arbitrator(s) may be entered in any court of competent
jurisdiction.

     (c) Claims for indemnification by Acquiror Indemnified Parties pursuant to
Section 9.02(a) shall be payable solely by offset by Acquiror against amounts
(if any) that become payable by Acquiror in accordance with Section 2.04

                                      A-51
<PAGE>
 
pursuant to the Contingent Payment Rights, and then only if such amounts both
(i) have not previously been paid by Acquiror to the Former Holders, and (ii)
would not have previously been paid by Acquiror to the Former Holders if
Acquiror were, at the time the claim is asserted, in full compliance with the
provisions of Section 2.04 (other than any noncompliance resulting from
withholding a payment in accordance with Section 2.04(j)).

     If any Earn-out payment becomes due at a time during which Acquiror has
pending a claim for indemnification pursuant to Section 9.02(a) (as limited by
Section 9.02(b)), then Acquiror may make such payment to the Former Holders
entitled thereto after deducting therefrom an amount equal to Acquiror's good
faith estimate of the amount of such claim. Acquiror shall pay interest on the
amount of any such deduction to the extent it is subsequently determined that
the actual amount of such claim is less than the amount so deducted at the rate
provided for in Section 9.05. Payments pursuant to this Section 9.03 shall be
distributed to the Former Holders in proportion to their respective interests in
Earn-out payments pursuant to this Agreement.
                                        
     SECTION 9.04  Expiration of Indemnities. The indemnification obligations 
set forth in Section 9.02(a) shall expire as to any claim that has not been
asserted as of 5:00 p.m., Minneapolis Time, on May 15, 1998; provided, however,
if any such claim is based on a breach of a representation or warranty relating
to any Community Health Entity, the obligation shall expire as to any claim that
has not been asserted as of 5:00 p.m., Minneapolis time, on May 15, 1997.

     SECTION 9.05  Indemnification Claims; Interest. Interest on any claim for
indemnification pursuant to this Article IX shall accrue at a floating rate
equal to the Prime Rate as published from time to time in the "Money Rates"
section of the Wall Street Journal, from the date the claim arose until the
claim is satisfied by payment.

     SECTION 9.06  Exclusivity of Indemnification; Right of Offset. After the
Closing, the indemnification rights of the Acquiror Indemnified Parties under
this Article IX shall be the sole and exclusive remedy of the Acquiror
Indemnified Parties arising from this Agreement; provided, that nothing in this
Article IX shall limit the ability of any party to seek prior to Closing
injunctive or other equitable relief for any breach of this Agreement; provided
further that nothing herein shall prevent any Indemnified Party from bringing an
action based upon allegations of fraud or with respect to any party in
connection with this Agreement and such other agreements. In the event such a
fraud action is brought, the prevailing party's attorneys' fees and costs shall
be paid by the nonprevailing party.

     SECTION 9.07.  Indemnification of Shareholders.

     (a) From and after the Effective Time, Acquiror shall, subject to the
limitations set forth in Section 9.07(b) below, indemnify and hold harmless the
former shareholders of the Company and the Shareholder Representative
(collectively, the "Shareholder Indemnified Parties") from and against any
Losses which any Shareholder Indemnified Party (but without duplication) may
suffer, sustain or become subject to as a result of (i) any representation or
warranty by Acquiror in this Agreement relating to the validity of the Acquiror
Common Stock received by such Shareholder Indemnified Party in connection with
the Merger, that it is not true and correct as of the date made, (ii) any breach
by Acquiror or the Surviving Corporation of any covenant or agreement contained
in this Agreement required to be performed after the Effective Time, (iii) any
claim by a person who held shares of Acquiror Common Stock prior to the
Effective Time against Acquiror or one or more directors or officers of Acquiror
alleging a breach of fiduciary duty or other improper action by such director(s)
or officer(s) in connection with the approval of the Merger, this Agreement and
the transactions contemplated hereby, or (iv) Taxes, if any, of any Shareholder
Indemnified Party, or any successor thereto, as a result of the failure of the
Merger to qualify as a tax-free reorganization under Section 368(a) of the Code
by reason of any actions taken by Acquiror or the Surviving Corporation after
the Effective Time.

     (b) The Shareholder Indemnified Parties shall be entitled to
indemnification for any Losses described in Section 9.07(a) only if a
Shareholder Indemnified Party delivers to Acquiror written notice, setting forth
in reasonable detail the basis of the claim and the identity, nature and (to the
extent known) amount of Losses related to such claim or claims prior to (i) 5:00
p.m., Minneapolis time, on May 15, 1998, if such claim is based on the untruth
or incorrectness of a representation or warranty of Acquiror, or (ii) two years
after the Shareholder Indemnified Party asserting the claim became aware of such
claim, in all other cases.

     (c) The provisions of Section 9.03 shall apply to indemnification pursuant
to Section 9.07(a) except that (i) "Shareholder Representative" in Section 9.03
shall mean Acquiror, and "Indemnified Party" and "Notifying Party" shall refer
to the Shareholder Indemnified Party who is entitled to indemnification under
this Section 9.07 (or to the Shareholder Representative acting in behalf of the
Indemnified Party), and (ii) the sixth sentence (beginning "Acquiror shall 
pay. . .") shall be disregarded.

     (d) Section 9.05 and 9.06 shall apply to the indemnification pursuant to
Section 9.07, for which purpose references to the Acquiror Indemnified Parties
shall mean the Shareholder Indemnified Parties.

                              GENERAL PROVISIONS

     SECTION 11.01  Arbitration.

     (a) Any dispute, controversy or claim arising out of or relating to this
Agreement or the agreements contemplated by this Agreement, the breach hereof or
thereof, or coverage of this arbitration provision which is not settled shall be
resolved by arbitration conducted in accordance with this Section 11.01. In such
cases the disputing parties will submit their differences to a panel of three
arbiters selected in accordance with Section 11.01(b) below. The arbiters will
make their award with a view to effectuating the intent of the parties; provided
that the arbiters shall have no authority to award punitive or exemplary damages
or to vary or ignore (but may interpret or construe) the terms of this Agreement
or the other agreements contemplated by this Agreement, and the arbiters shall
be bound by controlling Laws and legal precedent. In the event of disagreement
among the arbiters, the decision will rest with the majority. Each arbiter shall
be independent, and no arbiter shall be a present or former associate,
affiliate, attorney, director, officer or employee of any party or its
affiliates.

     (b) Arbitration may be initiated by Acquiror or by the Company or the
Shareholder Representative (the initiating party is referred to as the

                                      A-59
<PAGE>
 
"Petitioner") by written notice to the other party or parties demanding
arbitration and naming its arbiter. The other party or parties (collectively,
the "Respondent') shall have 20 days after receipt of said notice within which
to designate its arbiter. The third arbiter shall be chosen by the two arbiters
named by the Respondent and the Petitioner within 20 days thereafter and the
arbitration shall be held at the place hereinafter set forth ten days after the
appointment of the third arbiter. Should the two arbiters not be able to agree
on the choice of the third, each arbiter shall nominate three persons and the
other arbiter shall be entitled to reject one such person. The third arbiter
shall then be chosen by drawing lots. If the Respondent does not name its
arbiter within 20 days, the Petitioner may designate the second arbiter.
Arbitration shall take place in Louisiana.

     (c) The arbiters shall apply the Commercial Arbitration Rules of the
American Arbitration Association, except as may otherwise be agreed and
stipulated by all of the disputing parties prior to commencement of any
arbitration. The arbiters shall conduct the arbitration so that a final result,
determination, finding, judgment and/or award (a "Final Determination") is made
or rendered as soon as practicable, but in no event later than 90 days after the
third arbiter is chosen. The arbiters shall render a Final Determination within
15 days of completion of the arbitration. The Final Determination shall be final
and binding on all parties and there shall be no appeal from or reexamination of
the Final Determination, except (i) in the case of fraud, evident partiality or
misconduct by an arbiter which materially prejudices the rights of any party,
and (ii) to correct manifest clerical errors. Judgment may be entered upon the
Final Determination in any court of competent jurisdiction. If injunctive or
other equitable relief is permitted under this Agreement or otherwise
permissible under applicable law, either the arbiters or a court of competent
jurisdiction (if an arbitration panel cannot be timely convened or is otherwise
unavailable) shall be empowered to grant such injunctive or other equitable
relief on a permanent, preliminary or temporary basis, as appropriate under the
circumstances. The parties hereby irrevocably consent and submit to the
jurisdiction of the courts of or sitting in the State of Louisiana for all
purposes relative to any arbitration and to any subsequent entry of judgment on
any Final Determination rendered pursuant thereto. Subject to Section 8.03(c)
and Article IX: (i) the Petitioner and the Respondent each shall pay its own
attorneys' and witnesses' fees and expenses and other expenses connected with
the presentation of its case subject to Section 9.03(a) and (ii) the remaining
costs of any arbitration, including the cost of the record or transcripts
thereof, if any, administrative fees and other fees and expenses of the arbiters
shall be shared equally between the Petitioner and the Respondent.

     SECTION 11.02  Notices. All notices and other communications given or made
pursuant to this Agreement shall be in writing and shall be deemed to have been
duly given or made as of the date delivered, mailed or transmitted, and shall be

express courier, charges prepaid, to the parties at the following addresses (or

      SECTION 11.03  Amendment. This Agreement may be amended by the parties by
action taken by or on behalf of their respective Boards of Directors at any time
prior to the Effective Time; provided, however, that, after adoption of this

parties.

invalid, illegal or incapable of being enforced by any rule of Law or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated hereby is not affected in any manner materially
adverse to any party. Upon any such determination prior to the Effective Time
that any term or other provision is invalid, illegal or incapable of being
enforced, the parties shall negotiate in good faith to modify this Agreement so

the tax effect thereof: (a) interest expense, (b) expenses of the acquisition
transactions contemplated by the Agreement or goodwill therefrom or similar
expenses or goodwill from other acquisitions, and (c) matters for which any
Acquiror Indemnified Party has received, or will receive, indemnification under
Article IX.

     3.  There shall be added to Net Income the amount (if any) by which
"Adjusted Operating Expenses" (defined below) exceeds 10% of "Adjusted Premium
Revenues" (defined below), after deducting the tax effect of such excess
expenses. For purposes of this calculation, (a) Adjusted Operating Expenses
means all expenses (including any charges under a management contract or charges
for any services provided to the Community Health Entities by Acquiror or any
Affiliate of Acquiror or by any officer, director or employee of Acquiror or any
such Affiliate) other than (i) cost of Medical Services Expenses, (ii) expenses
added back to Net Income in accordance with 2. above, (iii) broker commissions,
and (iv) premium and other taxes; and (b) Adjusted Premium Revenues means all
premium revenues other than (i) interest and other investment income, (ii) fees
from self-funded groups, and (iii) miscellaneous management fees.

     4.  The Louisiana HMO operations acquired by Acquiror from The MetraHealth
Companies, Inc. will be deemed to be a Community Health Entity for all purposes
of calculating the Earn-Out.

     5.  Adjustments identified by the independent auditors of the Community
Health Entities as part of their standard audit procedures, which procedures
shall be in accordance with Generally Accepted Auditing Standards and consistent
with prior periods, will be considered not material in preparing the
consolidated financial statements only if the aggregate effect thereof, taking
in account both positive and negative adjustments, does not exceed $20,000.

Board of Directors
Louisiana Independent Physicians Association, Inc.
c/o Thomas H. Benton
601 St. Ferdinand Street
Baton Rouge, Louisiana  70802

Gentlemen:

       We understand that Louisiana Independent Physicians Association, Inc.
("LIPA" or the "Company") has entered into an Agreement and Plan of Merger (the
"Proposed Transaction") with UNC Gold Acquisition, Inc., a wholly-owned
subsidiary of United HealthCare Corporation ("United").  The Company is a
holding company which owns (i) 51% of the common stock of Community Health
Network of Louisiana, Inc., a Louisiana corporation, (ii) a 48.51% general
partnership interest in Louisiana Health Management Company, a Louisiana general
partnership ("LHMC"), and (iii) 49% of the common stock of Louisiana Health
Partners, Inc., a Louisiana corporation and the 1% owner and managing general
partner of LHMC.

       In connection with the Proposed Transaction, we understand that the
stockholders of LIPA shall receive approximately $50.0 million of United's
common stock as merger consideration at closing.  In addition, the stockholders
shall be entitled to cash earn-out payments up to an aggregate of $35.0 million
if the Company's net income in 1996 and 1997 exceeds certain minimum thresholds.
The combination of the initial stock payment and the potential earn-out payments
is herein referred to in the aggregate as the consideration (the
"Consideration").  A detailed description of the Proposed Transaction is
provided in the Agreement and Plan of Merger (the "Agreement").

       We have been requested by the Company to render our opinion (the
"Opinion") with respect to the fairness, from a financial point of view, to the
Company's stockholders of the Consideration to be received by the Company's
stockholders in the Proposed Transaction.  We have not been requested to opine
as to, and our opinion does not in any manner address, the Company's underlying
business decision to proceed with or effect the Proposed Transaction.

       In arriving at our Opinion, we reviewed and analyzed: (i) the Agreement,
(ii) financial and operating information with respect to the business,
operations and prospects of the Company furnished to us by the Company, (iii) a
comparison of the historical financial results and present financial condition
of the Company with those of other companies which we deemed relevant, (iv) an
analysis of financial and stock market information of selected publicly-traded
companies which we deemed comparable to the Company, (v) a comparison of the
financial terms of the Proposed Transaction with the financial terms of certain
other recent transactions which we deemed relevant, (vi) analyses of the present
value of the free cash flows projected to be generated by the Company during the
forecast period, and (vii) certain information regarding

United, including, among others, (a) certain recent filings with the Securities
and Exchange Commission, (b) equity research reports published by analysts
within the investment community who provide research coverage of United, (c) the
recent trading and volume history of United's stock, and (d) historical and
projected financial information of the Louisiana HMO operations of the
MetraHealth Companies, Inc. acquired by United. In addition, we held discussions
with the management of the Company and United concerning their respective
businesses and operations, assets, present conditions and future prospects and
undertook such other studies, analyses and investigations as we deemed
appropriate.

       We have relied upon the accuracy and completeness of the financial and
other information used by us in arriving at our Opinion without independent
verification and have further relied upon the assurances of management of the
Company that it is not aware of any facts that would make such information
inaccurate or misleading.  In arriving at our Opinion, we have not conducted a
physical inspection of the properties and facilities of the Company.  We have
not made nor obtained any evaluations or appraisals of the assets or liabilities
of the Company.  Our Opinion is necessarily based upon market, economic and
other conditions as they exist and can be evaluated as of the date of this
letter.

       We have acted as financial advisor to the Company in connection with the
Proposed Transaction and will receive a fee for our services which will be paid
upon the delivery of this Opinion.  In addition, the Company has agreed to
indemnify us for certain potential liabilities arising out of the rendering of
this Opinion.

       Based upon and subject to the foregoing, we are of the Opinion as of the
date hereof that, from a financial point of view, the Consideration to be
received by the Company's stockholders in the Proposed Transaction is fair to
the stockholders of the Company.

       This opinion is solely for the use and benefit of the Board of Directors
of the Company and shall not be disclosed publicly or made available to, or
relied upon by, any third party without our prior approval except that (i) this
opinion may be filed with the Securities and Exchange Commission as an exhibit
to the registration statement on Form S-4 being filed by United in connection
with the Proposed Transaction; and (ii) this opinion may be described in, and a
copy hereof may be annexed to, the proxy statement to be circulated to the
stockholders of the Company in connection with the Proposed Transaction.  This
Opinion is not intended to be and does not constitute a recommendation to any
stockholder as to how such stockholder should vote with respect to the Proposed
Transaction.

                                       Very truly yours,

                                                                       EXHIBIT C

     LOUISIANA BUSINESS CORPORATION LAW SECTION 12:131--RIGHTS OF SHAREHOLDER 
DISSENTING FROM CERTAIN CORPORATE ACTIONS.

     A.  Except as provided in subsection B of this Section if a corporation
has, by vote of its shareholders, authorized a sale, lease or exchange of all of
its assets, or has, by vote of its shareholders, become a party to a merger or
consolidation, then, unless such authorization or action shall have been given
or approved by at least eighty per cent of the total voting power, a shareholder
who voted against such corporate action shall have the right to dissent.  If a
corporation has become a party to a merger pursuant to R.S. 12:112(H), the
shareholders of any subsidiaries party to the merger shall have the right to
dissent without regard to the proportion of the voting power which approved the
merger and despite the fact that the merger was not approved by vote of the
shareholders of any of the corporations involved.

     B.  The right to dissent provided by this Section shall not exist in the
case of:

     (1)  A sale pursuant to an order of a court having jurisdiction in the
premises.

     (2)  A sale for cash on terms requiring distribution of all or 
substantially all of the net proceeds to the shareholders in accordance with
their respective interests within one year after the date of the sale.

     (3)  Shareholders holding shares of any class of stock which, at the record
date fixed to determine shareholders entitled to receive notice of and to vote
at the meeting of shareholders at which a merger or consolidation was acted on,
were listed on a national securities exchange, or were designated as a national
market system security on an inter-dealer quotation system by the National
Association of Securities Dealers, unless the articles of the corporation
issuing such stock provide otherwise or the shares of such shareholders were not
converted by the merger or consolidation solely into shares of the surviving or
new corporation.
    
     C.  Except as provided in the last sentence of this subsection, any
shareholder electing to exercise such right of dissent shall file with the
corporation, prior to or at the meeting of shareholders at which such proposed
corporate action is submitted to a vote, a written objection to such proposed
corporate action, and shall vote his shares against such action.  If such
proposed corporate action be taken by the required vote, but by less than eighty
per cent of the total voting power, and the merger, consolidation or sale, lease
or exchange of assets authorized thereby be effected, the corporation shall
promptly thereafter give written notice thereof, by registered mail, to each
shareholder who filed such written objection to, and voted his shares against,
such action, at such shareholder's last address on the corporation's records.
Each such shareholder may, within twenty days after the mailing of such      

                                      C-1

<PAGE>
     
notice to him, but not thereafter, file with the corporation a demand in writing
for the fair cash value of his shares as of the day before such vote was taken;
provided that he state in such demand the value demanded, and a post office
address to which the reply of the corporation may be sent, and at the same time
deposit in escrow in a chartered bank or trust company located in the parish of
the registered office of the corporation, the certificates representing his
shares, duly endorsed and transferred to the corporation upon the sole condition
that said certificates shall be delivered to the corporation upon payment of the
value of the shares determined in accordance with the provisions of this
Section. With his demand the shareholder shall deliver to the corporation, the
written acknowledgement of such bank or trust company that it so holds his
certificates of stock. Unless the objection, demand and acknowledgement
aforesaid be made and delivered by the shareholder within the period above
limited, he shall conclusively be presumed to have acquiesced in the corporate
action proposed or taken. In the case of a merger pursuant to R.S. 12:112(H),
the dissenting shareholder need not file an objection with the corporation nor
vote against the merger, but need only file with the corporation, within twenty
days after a copy of the merger certificate was mailed to him, a demand in
writing for the cash value of his shares as of the day before the certificate
was filed with the Secretary of State, state in such demand the value demanded
and a post office address to which the corporation's reply may be sent, deposit
the certificates representing his shares in escrow as hereinabove provided, and
deliver to the corporation with his demand the acknowledgement of the escrow
bank or trust company as hereinabove prescribed.     

     D.  If the corporation does not agree to the value so stated and demanded,
or does not agree that a payment is due, it shall, within twenty days after
receipt of such demand and acknowledgement, notify in writing the shareholder,
at the designated post office address, of its disagreement, and shall state in
such notice the value it will agree to pay if any payment should be held to be
due; otherwise it shall be liable for, and shall pay to the dissatisfied
shareholder, the value demanded by him for his shares.

     E.  In the case of disagreement as to such fair cash value, or as to
whether any payment is due, after compliance by the parties with the provisions
of subsections C and D of this Section, the dissatisfied shareholder, within
sixty days after receipt of notice in writing of the corporation's disagreement,
but not thereafter, may file suit against the corporation, or the merged or
consolidated corporation, as the case may be, in the district court of the
parish in which the corporation or the merged or consolidated corporation, as
the case may be, has its registered office, praying the court to fix and decree
the fair cash value of the dissatisfied shareholder's shares as of the day
before such corporate action complained of was taken, and the court shall, on
such evidence as may be adduced in relation thereto, determine summarily whether
any payment is due, and, if so, such cash value, and render judgment
accordingly.  Any shareholder entitled to file 

                                      C-2
<PAGE>
 
such suit may, within such sixty-day period but not thereafter, intervene as a
plaintiff in such suit filed by another shareholder, and recover therein
judgment against the corporation for the fair cash value of his shares. No order
or decree shall be made by the court staying the proposed corporate action, and
any such corporate action may be carried to completion notwithstanding any such
suit. Failure of the shareholder to bring suit, or to intervene in such a suit,
within sixty days after receipt of notice of disagreement by the corporation
shall conclusively bind the shareholder (1) by the corporation's statement that
no payment is due, or (2) if the corporation does not contend that no payment is
due, to accept the value of his shares as fixed by the corporation in its notice
of disagreement.

     F.  When the fair value of the shares has been agreed upon between the
shareholder and the corporation, or when the corporation has become liable for
the value demanded by the shareholder because of failure to give notice of
disagreement and of the value it will pay, or when the shareholder has become
bound to accept the value the corporation agrees is due because of his failure
to bring suit within sixty days after receipt of notice of the corporation's
disagreement, the action of the shareholder to recover such value must be
brought within five years from the date the value was agreed upon, or the
liability of the corporation became fixed.

     G.  If the corporation or the merged or consolidated corporation, as the
case may be, shall, in its notice of disagreement, have offered to pay to the
dissatisfied shareholder on demand an amount in cash deemed by it to be the fair
cash value of his shares, and if, on the institution of a suit by the
dissatisfied shareholder claiming an amount in excess of the amount so offered,
the corporation, or the merged or consolidated corporation, as the case may be,
shall deposit in the registry of the court, there to remain until the final
determination of the cause, the amount so offered, then, if the amount finally
awarded such shareholder, exclusive of interest and costs, be more than the
amount offered and deposited as aforesaid, the costs of the proceeding shall be
taxed against the corporation, or the merged or consolidated corporation, as the
case may be; otherwise the costs of the proceeding shall be taxed against such
shareholder.

     H.  Upon filing a demand for the value of his shares, the shareholder
shall cease to have any of the rights of a shareholder except the rights
accorded by this Section.  Such a demand may be withdrawn by the shareholder for
any time before the corporation gives notice of disagreement, as provided in
subsection D of this Section.  After such notice of disagreement is given,
withdrawal of a notice of election shall require the written consent of the
corporation.  If a notice of election is withdrawn, or the proposed corporate
action is abandoned or rescinded, or a court shall determine that the
shareholder is not entitled to receive payment for his shares, or the
shareholder shall otherwise lose his dissenter's rights, he shall not have the
right to receive payment for his shares, his share certificates shall be

                                      C-3
<PAGE>
 
returned to him (and, on his request, new certificates shall be issued to him in
exchange for the old ones endorsed to the corporation), and he shall be
reinstated to all his rights as a shareholder as of the filing of his demand for
value, including any intervening preemptive rights, and the right to payment of
any intervening dividend or other distribution, or, if any such rights have
expired or any such dividend or distribution other than in cash has been
completed, in lieu thereof, at the election of the corporation, the fair value
thereof in cash as determined by the board as of the time of such expiration or
completion, but without prejudice otherwise to any corporate proceedings that
may have been taken in the interim.

                    INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  Indemnification of Officers and Directors.

     Minnesota Statutes Section 302A.521 provides that a corporation shall
indemnify any person made or threatened to be made a party to a proceeding by
reason of the former or present official capacity of such person against
judgments, penalties, fines (including, without limitation, excise taxes
assessed against such person with respect to any employee benefit plan),
settlements and reasonable expenses, including attorneys' fees and
disbursements, incurred by such person in connection with the proceeding, if,
with respect to the acts or omissions of such person complained of in the
proceeding, such person (1) has not been indemnified therefor by another
organization or employee benefit plan; (2) acted in good faith; (3) received no
improper personal benefit and Section 302A.255 (with respect to director
conflicts of interest), if applicable, has been satisfied; (4) in the case of a
criminal proceeding, had no reasonable cause to believe the conduct was
unlawful; and (5) reasonably believed that the conduct was in the best interests
of the corporation in the case of acts or omissions in such person's official
capacity for the corporation or reasonably believed that the conduct was not
opposed to the best interests of the corporation in the case of acts or
omissions in such person's official capacity for other affiliated organizations.
Article IX of the Bylaws of United provides that United shall indemnify officers
and directors to the extent permitted by Section 302A.521 as now enacted or
hereafter amended.

     United also carries a directors' and officers' liability insurance policy.

ITEM 22.  Undertakings.  The undersigned Registrant hereby undertakes:

     (a)(1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this Registration Statement:

          (A)  To include any prospectus required by Section 10(a)(3) of the
               Securities Act of 1933;

          (B)  To reflect in the prospectus any facts or events arising after
               the effective date of the registration statement (or the most
               recent post-effective amendment thereof) which, individually or
               in the aggregate, represent a fundamental change in the
               information set forth in the registration statement.
               Notwithstanding the foregoing, any increase or decrease in volume
               of securities offered (if the total dollar value of securities
               offered would not exceed that which was registered) and any
               deviation from the low or high end of the estimated maximum
               offering range may be reflected in the form of prospectus filed
               with the Commission pursuant to Rule 424(b) if, in the aggregate,
               the changes in volume and price represent no more than a 20%
               change in the maximum aggregate offering price set forth in the
               "Calculation of Registration Fee" table in the effective
               Registration Statement.

          (C)  To include any material information with respect to the plan of
               distribution not previously disclosed in the registration
               statement or any material change to such information in the
               registration statement;

     (2) 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

                                      II-2
<PAGE>
 
     (3) 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.

     (b)(1) That prior to any public reoffering of the securities registered
hereunder through use of a prospectus which is a part of this registration
statement, by any person or party who is deemed to be an underwriter within the
meaning of Rule 145(c), such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form; and

     (2) That every prospectus (A) that is filed pursuant to paragraph (1)
immediately preceding, or (B) that purports to meet the requirements of section
10(a)(3) of the Securities Act of 1933 and is used in connection with an
offering of securities subject to Rule 415, will be filed as a part of an
amendment to the Registration Statement and will not be used until such
amendment is effective and that, for purposes 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.

     (c) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, 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 Act 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 action, suit or proceeding) is asserted by such
director, 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 Act and will be governed by the final adjudication of
such issue.

     (d) To respond to requests for information that is incorporated by
reference into the Prospectus pursuant to Items 4, 10(b), 11 or 13 of this Form,
within one business day of receipt of such request, and to send the incorporated
documents by first class mail or other equally prompt means. This includes
information contained in documents filed subsequent to the effective date of the
Registration Statement through the date of responding to the request.

     (e) To supply by means of a post-effective amendment all information
concerning a transaction, and the company being acquired involved therein, that
was not the subject of and included in the Registration Statement when it became
effective.

                                     II-3
<PAGE>
 
     (f) For purposes of determining any liability under the Securities Act,
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.
