ITEM 5. OTHER EVENTS.


     On September 17, 1996, PacifiCare Health Systems, Inc. (the "Registrant")
entered into the Amended and Restated Agreement and Plan of Reorganization (the
"Reorganization Agreement") with FHP International Corporation ("FHP"), which
amends the Agreement and Plan of Reorganization entered into on August 4, 1996
by the Registrant and FHP (the "Original Reorganization Agreement").  The
Reorganization Agreement modifies the Original Reorganization Agreement by
providing an alternative exchange formula in the event that the stockholders of
FHP fail to approve an amendment to the FHP Certificate of Incorporation (the
"FHP Certificate") to: (i) exempt the merger of Tree Acquisition Corporation
with and into FHP (the "FHP Merger") from a requirement of the existing FHP
Certificate that, in the event of a merger or consolidation of FHP, the holders
of FHP Preferred Stock are entitled to receive upon conversion thereof the same
consideration per share as the consideration per share they would have received
in the event they converted their FHP Preferred Stock into FHP Common Stock
immediately prior to such merger or consolidation; and (ii) provide that the
holders of FHP Preferred Stock are not entitled to Special Conversion Rights (as
defined in the existing FHP Certificate) as a result of the FHP Merger.  The
Reorganization Agreement also clarifies various other provisions of the Original
Reorganization Agreement.  The Reorganization Agreement is filed herewith as
Exhibit 2.1.

     On September 9, 1996, the Registrant announced that it received notice from
the Health Care Financing Administration that its Secure Horizons-Registered
Trademark- Medicare risk programs will receive an overall weighted average
premium rate increase of approximately 6.1 percent for the calendar year
beginning January 1, 1997.  The calendar year 1997 average rate increase varies
by state and other demographic factors and compares to the approximately 5.6
percent overall increase received for the 1996 calendar year.  The Registrant
issued a press release announcing the calendar year 1997 average rate increase,
which is filed herewith as Exhibit 99.1.

     On September 20, 1996, the Registrant and FHP jointly announced that the
U.S. Federal Trade Commission had, in accordance with the regulations
promulgated under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended, requested additional documentation regarding the proposed acquisition
transaction involving the Registrant and FHP (the "Second Request").  The
Registrant issued a press release announcing the Second Request, which is filed
herewith as Exhibit 99.2.

                              AMENDED AND RESTATED
                      AGREEMENT AND PLAN OF REORGANIZATION
 
    THIS AMENDED AND RESTATED AGREEMENT AND PLAN OF REORGANIZATION (this
"Agreement") is made and entered into as of September 17, 1996, by and among:
N-T HOLDINGS, INC., a Delaware corporation ("Holding"), PACIFICARE HEALTH
SYSTEMS, INC., a Delaware corporation ("PacifiCare"); NEPTUNE MERGER CORP., a
Delaware corporation and a wholly-owned subsidiary of Holding ("Neptune Sub");
FHP INTERNATIONAL CORPORATION, a Delaware corporation (the "Company"), and TREE
ACQUISITION CORP., a Delaware corporation and a wholly-owned subsidiary of
Holding ("Company Sub") who hereby amend and entirely restate the Agreement and
Plan of Reorganization among the same parties dated as of August 4, 1996 (the
"Original Agreement").
 
                                    RECITALS
 
    A.  The parties intend concurrently to effect a merger of Neptune Sub into
PacifiCare (the "PacifiCare Merger") and a merger of Company Sub into Company
(the "Company Merger"), each such merger to be carried out in accordance with
this Agreement and the laws of the State of Delaware (the "Mergers"), such that
PacifiCare and Company become wholly-owned subsidiaries of Holding and the
shareholders of PacifiCare and Company become shareholders of Holding. After the
Closing, Holding will act as a holding company for PacifiCare and the Company.
 
    B.  This Agreement has been approved by the respective Boards of Directors
of Holding, PacifiCare, Neptune Sub, Company and Company Sub.
 
    C.  For United States federal income tax purposes, it is intended that the
transactions contemplated by this Agreement qualify as transfers subject to
Section 351(a) of the Internal Revenue Code of 1986, as amended, and the rules
and regulations promulgated thereunder (the "Code") and that the shareholders of
the Company be treated as if they transferred their stock in Company to Holding
in exchange for the Company merger consideration and that the shareholders of
PacifiCare be treated as if they transferred their stock in PacifiCare to
Holding in exchange for the PacifiCare merger consideration.
 
    D.  On August 4, 1996 PacifiCare had issued and outstanding approximately
12,370,758 shares of Class A Common Stock, $0.01 par value ("PacifiCare Class A
Common Stock") and 18,812,799 shares of Class B Common Stock, $0.01 par value
("PacifiCare Class B Common Stock"). On August 4, 1996 the Company had issued
and outstanding approximately 40,806,165 shares of Common Stock, $0.05 par value
("Company Common Stock") and approximately 21,030,345 shares of Series A
Cumulative Convertible Preferred Stock, $0.05 par value ("Company Series A
Preferred Stock").
 
    E.  Contemporaneously with the execution and delivery of the Original
Agreement, certain stockholders of PacifiCare and of the Company executed Voting
and Non-Disposition Agreements.
 
                                   AGREEMENT
 
    Holding, PacifiCare, Neptune Sub, the Company, and Company Sub hereby agree
as follows:
 
                                   ARTICLE 1
                           DESCRIPTION OF TRANSACTION
 
    1.1  MERGERS.  Upon the terms and subject to the conditions set forth in
this Agreement, at the Effective Time (as defined in Section 1.3), Company Sub
shall be merged into the Company and the separate existence of the Company Sub
shall cease. The Company will be the surviving corporation in the Company Merger
(the "Company Surviving Corporation") and its separate corporate existence, with
all its purposes, objects, rights, privileges, powers and franchises shall
continue unaffected by such merger. Upon the terms and subject to the conditions
set forth in this Agreement, at the Effective
 
                                       1
<PAGE>
Time, Neptune Sub shall be merged into PacifiCare and the separate existence of
Neptune Sub shall cease. PacifiCare shall be the surviving corporation in
PacifiCare Merger ("PacifiCare Surviving Corporation") and its separate
corporate existence, with all its purposes, objects, rights, privileges, powers
and franchises shall continue unaffected by such merger. Company Sub and Neptune
Sub have been formed solely for the purpose of effecting the Company Merger and
the PacifiCare Merger, respectively, and there will be no other activity in
Company Sub and Neptune Sub.
 
    1.2  EFFECT OF THE MERGERS.  The Mergers shall have the effects set forth in
this Agreement and in Section 259 of the Delaware General Corporation Law (the
"DGCL").
 
    1.3  CLOSING; EFFECTIVE TIME.  The consummation of the transactions
contemplated by this Agreement (the "Closing") shall take place at the offices
of PacifiCare on the second business day following the date as of which each of
the conditions set forth in Articles 5 and 6 has been fulfilled or waived or on
such other date or at such other place as may be jointly designated by
PacifiCare and the Company (the "Closing Date"). As soon as practicable after
the Closing, properly executed certificates of merger for each Merger conforming
to the requirements of the DGCL and changing the name of Holding to "PacifiCare
Health Systems, Inc." and the name of PacifiCare to "PacifiCare Operations,
Inc." or some other name chosen by PacifiCare, shall be filed with the Delaware
Secretary of State. The Mergers shall become effective at the time said
certificates of merger are filed with the Delaware Secretary of State or at such
later time as may be specified in said certificates of merger (the "Effective
Time").
 
    1.4  CERTIFICATES OF INCORPORATION AND BYLAWS; DIRECTORS AND OFFICERS.
 
    (a)  The Certificates of Incorporation of PacifiCare and Company shall be
the Certificates of Incorporation of PacifiCare Surviving Corporation and the
Company Surviving Corporation, respectively, as of the Effective Time.
 
    (b)  The Bylaws of PacifiCare and the Company, as in effect immediately
prior to the Effective Time, shall become the Bylaws of PacifiCare Surviving
Corporation and the Company Surviving Corporation, respectively, at the
Effective Time.
 
    (c)  The directors of the Company shall resign or be removed concurrently
with the Effective Time.
 
    (d)  PacifiCare shall cause Holding to take all necessary corporate action
to amend the Certificate of Incorporation and Bylaws of Holding prior to the
Effective Time to be in substantially the form of the Amended and Restated
Certificate of Incorporation attached hereto as Exhibit 1.4A (the "Holding
Restated Certificate of Incorporation") and the Bylaws of PacifiCare in effect
on the date hereof; PROVIDED, HOWEVER, that if the Series A Required Vote (as
defined in Section 2.11) is not received for the Series A Amendment (as defined
in Section 2.11), PacifiCare shall cause Holding to take all necessary corporate
action to amend the Certificate of Incorporation of Holding prior to the
Effective Time to be in substantially the form of the Amended and Restated
Certificate of Incorporation attached hereto as Exhibit 1.4B (the "Holding
Restated Certificate of Incorporation without Series A") instead of the Holding
Restated Certificate of Incorporation; and, PROVIDED FURTHER, that the
indemnification provisions of the Bylaws of Holding may be amended to provide
additional indemnification rights to the Directors and/or Officers of Holding.
PacifiCare shall cause the Board of Directors of Holding after the Effective
Time to consist of at least ten persons, of which two individuals shall be
designated by the Board of Directors of the Company and be reasonably
satisfactory to the Board of Directors of PacifiCare. The designation of such
new directors by the Board of Directors of the Company, and the approval of such
new directors by the Board of Directors of PacifiCare shall each occur prior to
the Effective Time. Such new directors shall be appointed to different classes,
and they shall commence to serve within 60 days of the Effective Time and remain
as directors until their successors have been duly elected or until their
earlier death, removal or resignation, provided that they shall be renominated
as required to be able to serve a minimum of three years. If, prior to the end
of such period, either of such directors becomes unable to serve as director, or
is no longer qualified to
 
                                       2
<PAGE>
serve as a director, the remaining director (or his successor) shall select a
replacement nominee (which nominee shall be satisfactory to the Board of
Directors of Holding) to be appointed to serve the remaining term.
 
    1.5  CONVERSION OF SHARES.
 
    (a)  At the Effective Time, by virtue of the Company Merger (and without any
action on the part of any stockholder of the Company):
 
        (i) any shares of Company Common Stock or Company Series A Preferred
    Stock then held by the Company or any subsidiary of the Company (or held in
    the Company's treasury) shall be canceled;
 
        (ii) any shares of Company Common Stock or Company Series A Preferred
    Stock then held by PacifiCare, Neptune Sub or any other subsidiary of
    PacifiCare shall be canceled;
 
       (iii) except as provided in clauses (i) and (ii) above or as provided in
    Section 1.8 with respect to shares as to which appraisal rights have been
    exercised and subject to Section 1.5(c) below, each share of Company Common
    Stock outstanding immediately prior to the Effective Time shall be converted
    into the right to receive:
 
           (A)  an amount of Cash equal to $17.50 (the "Common Cash
       Consideration"), plus
 
           (B)  the Final Class A/Common Share Ratio (as defined in Section
       1.5(a)(vi)(D) below) of a share of Holding's Class A Common Stock, $.01
       par value, as provided in the Holding Restated Certificate of
       Incorporation or Holding Restated Certificate of Incorporation without
       Series A, as the case may be ("Holding Class A Common Stock"), plus
 
           (C)  the Final Class B/Common Share Ratio (as defined in Section
       1.5(a)(vi)(E) below) of a share of Holding's Class B Common Stock, $.01
       par value, as provided in the Holding Restated Certificate of
       Incorporation or Holding Restated Certificate of Incorporation without
       Series A, as the case may be ("Holding Class B Common Stock");
 
           (D)  Talbert Rights as specified in Section 1.5(a)(v) below.
 
       (iv) except as provided in clauses (i) and (ii) above and subject to
    Section 1.5(c), each share of Company Series A Preferred Stock outstanding
    immediately prior to the Effective Time shall be converted into Talbert
    Rights as specified in Section 1.5(a)(v) below and the other consideration
    specified in this clause (iv).
 
    If the Series A Required vote is received for Series A Amendment, each share
of Series A Preferred Stock shall, in addition to the consideration described in
the first sentence of this Section 1.5(a)(iv), be converted into (A) an amount
of cash equal to $14.113 (the "Series A Cash Consideration"); and (B) and
one-half ( 1/2) share of Holding Series A (as defined in section 1.7(a)).
 
    If the Series A Required Vote is not received for the Series A Amendment,
then, in accordance with the Company's Certificate of Incorporation, the Company
shall, on the date of the Effective Time (or as soon thereafter as practicable
and in any event within 5 days thereof), give notice (the "Conversion Notice")
in accordance with the Company's Certificate of Designation with respect to the
Company Series A Preferred Stock (the "Certificate of Designation") to all
holders of Company Series A Preferred Stock that a "Change of Control" (as
defined in the Certificate of Designation) has occurred on the date of the
Effective Time and that such holders may exercise certain "Special Conversion
Rights," as defined in the Certificate of Designation, by delivery of written
notice of exercise of such rights, together with certificates representing the
Company Series A Preferred Stock with respect to which such rights are being
exercised, duly endorsed for transfer, until the expiration of 55 days from the
date of the Conversion Notice. Such Conversion Notice shall also include such
other information as may be required by the Certificate of Designation. In
accordance with the Certificate of Designation, each holder of Company Series A
Preferred Stock shall be entitled, upon exercise of such Special Conversion
Rights, to convert each share of Company Series A Preferred
 
                                       3
<PAGE>
Stock into either (A) the consideration to be received by a holder of a single
share of Company Common Stock pursuant to Section 1.5(a)(iii) times a fraction,
the numerator of which is $25.00 and the denominator of which is equal to the
closing price of the Company Common Stock on the last business day prior to the
date the Company gives the Conversion Notice to the holders of the Company
Series A Preferred Stock or (B) $25.00 cash plus any accrued but unpaid
dividends on such share; PROVIDED, HOWEVER, that if any holder elects the option
specified in clause (A) above, Holding (directly or through the Company
Surviving Corporation) may, at its option, elect to pay such holder $25.00 cash
plus any accrued but unpaid dividends on such share instead of the consideration
set forth in said clause (A). The Conversion Notice shall also provide that the
holders of Company Series A Preferred Stock may elect to waive their Special
Conversion Rights and elect to receive the same consideration in the Company
Merger that such holder would have received if such holder had converted such
holder's shares of Company Series A Preferred Stock into Company Common Stock
pursuant to such holder's regular conversion rights immediately prior to the
Effective Time ("As-If-Converted Company Merger Consideration"). If any holder
of Company Series A Preferred Stock fails to exercise such holder's Special
Conversion Rights or to waive such rights and elect to receive As-If-Converted
Company Merger Consideration within the time period specified in this Section
1.5(a)(iv) and the Certificate of Designation, such holder shall thereafter have
only the right to surrender such shares in accordance with the provisions of
Section 1.7 and to receive for each share the As-If-Converted Company Merger
Consideration.
 
        (v) Subject to Section 1.8 and subject to completion of the transactions
    contemplated by Section 4.15, at the Effective Time, by virtue of the
    Company Merger (and without any action on the part of any stockholder of the
    Company) each share of Company Common Stock and Company Series A Preferred
    Stock outstanding immediately prior to the Effective Time shall be converted
    in part into rights to purchase directly or indirectly through one or more
    other corporations formed to facilitate such purchase, all of the Company's
    interest in Talbert Medical Management Corporation and Talbert Health
    Services Corporation (collectively, "Talbert") pro rata based on the number
    of then outstanding shares of Company Common Stock and the number of shares
    of Company Common Stock into which outstanding shares of Company Series A
    Preferred Stock are convertible immediately prior to the Effective Time.
 
       (vi) for purposes of this Agreement:
 
           (A)  the "Average Pre-Vote Closing Share Price" for the PacifiCare
       Class B Common Stock shall be the average closing price as quoted in the
       Wall Street Journal of PacifiCare's Class B Common Stock ("PacifiCare
       Class B Common Stock") during the twenty trading days ending on the
       trading date immediately prior to the date of the stockholder meeting at
       which the Company's stockholders vote on whether to approve the Company
       Merger,
 
           (B)  the "Initial Exchange Ratio" shall be .258,
 
           (C)  the "Closing Price/Signing Price Ratio" shall be the Average
       Pre-Vote Closing Share Price for PacifiCare Class B Common Stock divided
       by $68.00,
 
           (D)  the "Final Class A/Common Share Ratio" shall be 2,350,000
       divided by the Common Outstanding Number (as defined in Section
       1.5(a)(vi)(G)), calculated to the nearest .001,
 
           (E)  the "Final Class B/Common Share Ratio" shall be the Final
       Exchange Ratio minus the Final Class A/Common Share Ratio,
 
                                       4
<PAGE>
           (F)  the "Final Exchange Ratio" shall be the product of the Initial
       Exchange Ratio times the following multiplier, calculated to the nearest
       .001:

</TABLE>
 
           (G)  The "Common Outstanding Number" shall be the number of shares of
       Company Common Stock issued and outstanding immediately before the
       Effective Time plus the number of shares of Company Common Stock subject
       to Company Options (as defined below), if any, which at the Effective
       Time have the right to receive, upon exercise, the consideration set
       forth in Section 1.5(a)(iii) after the Effective Time; PROVIDED, HOWEVER,
       that if the Series A Required Vote is not received for the Series A
       Amendment, then the "Common Outstanding Number" shall also include the
       number of shares of Company Common Stock into which the Company Series A
       Preferred Stock outstanding immediately prior to the Effective Time could
       be converted.
 
       (vii) each share of the Common Stock, par value $.01 per share, of
    Company Sub outstanding shall be converted into an equal number of shares of
    Company Common Stock.
 
    (b)  At the Effective Time, by virtue of the PacifiCare Merger (and without
any action on the part of any stockholder of PacifiCare):
 
        (i) any shares of PacifiCare Class A Common Stock or PacifiCare Class B
    Common Stock (PacifiCare Class A Common Stock and PacifiCare Class B Common
    Stock being sometimes collectively referred to herein as "PacifiCare Common
    Stock") then held by PacifiCare or any subsidiary of PacifiCare (or held in
    PacifiCare's treasury) shall be canceled and no payment shall be made with
    respect thereto;
 
        (ii) any shares of PacifiCare Common Stock then held by the Company,
    Company Sub or any other subsidiary of the Company shall be canceled;
 
       (iii) except as provided in clauses (i) and (ii) above and subject to
    Section 1.5(c) below, each share of PacifiCare Class A Common Stock then
    outstanding shall be converted into the right to receive one share of
    Holding Class A Common Stock and each share of PacifiCare Class B Common
    Stock then outstanding shall be converted into the right to receive one
    share of Holding Class B Common Stock (Holding Class A Common Stock and
    Holding Class B Common Stock being sometimes collectively referred to herein
    as "Holding Common Stock");
 
       (iv) each share of Common Stock, par value $.001 per share, of Neptune

    Common Stock; and
 
        (v) each share of the capital stock of Holding existing immediately
    prior to the Effective Time shall be canceled.
 
    (c)  If, between the date of this Agreement and the Effective Time, the
outstanding shares of Company Common Stock or Company Series A Preferred Stock
or PacifiCare Class A Common Stock or PacifiCare Class B Common Stock are
changed into a different number or class of shares by reason of any stock
dividend, subdivision, reclassification, recapitalization, split-up, combination
or similar transaction, the exchange ratio applicable thereto shall be
appropriately adjusted.

shall be canceled and exchanged as provided in Section 1.7.
 
    1.7  EXCHANGE OF CERTIFICATES.
 
    (a)  If the Series A Required Vote is received for the Series A Amendment,
the Holding Restated Certificate of Incorporation shall establish the terms of
Holding's preferred stock, including the Series A Preferred Stock (the "Holding

Secretary of State of the State of Delaware prior to the Effective Time. The
Holding Series A shall be convertible into Holding Class B Common Stock upon the

forth in Exhibit 1.4A.
 
    (b)  Prior to the Closing Date, PacifiCare shall select a reputable bank or

Promptly after the Effective Time, (i) Holding shall deposit with the Exchange
Agent certificates representing the shares of Holding Class A Common Stock,

the Series A Amendment, Holding Series A issuable pursuant to Section 1.5 and
(ii) Holding shall deposit cash sufficient to make the payments called for in
Section 1.5 and payments in lieu of fractional shares in accordance with Section
1.7(e). The shares of Holding Class A Common Stock, Holding Class B Common Stock
and Holding Series A, if any, and cash amounts so deposited with the Exchange
Agent, together with any dividends or distributions received by the Exchange
Agent with respect to such shares, are referred to collectively as the "Exchange
Fund."
 
    (c)  As soon as practicable after the Effective Time, the Exchange Agent
will mail to the holders of Old Stock Certificates (i) a letter of transmittal
in customary form and containing such provisions as Holding or PacifiCare may
reasonably specify and (ii) instructions for use in effecting the surrender of
Old Stock Certificates in exchange for the consideration set forth in Section
1.5. If the Series A Required Vote is not received for the Series A Amendment,
the Exchange Agent may (i) delay mailing the letter of transmittal for holders
of Company Series A Preferred Stock until after expiration of the period during
which Special Conversion Rights may be exercised or (ii) include the letter of
transmittal with the Conversion Notice. Upon surrender of an Old Stock
Certificate to the Exchange Agent for exchange, together with a duly executed
letter of transmittal and such other documents as may be reasonably required by
the Exchange Agent, the holder of such Old Stock Certificate shall be entitled
to receive in exchange therefor (i) in the case of holders of Company Common
Stock, (A) a check in the amount calculated pursuant to this Article 1 (subject
to required tax withholding) and (B) certificates representing the number of
whole shares of Holding Class A Common Stock and Holding Class B Common Stock
that such holder has the right to receive pursuant to the provisions of this
Article 1; (ii) in the case of holders of Company Series A Preferred Stock if
the Series A Required Vote is received for the Series A Amendment, (A) a check
in the amount calculated pursuant to this Article 1 (subject to required tax
withholding), and (B) a certificate representing the whole number of shares of
Holding Series A that such holder has the right to receive pursuant to the
provisions of this Article 1; (iii) in the case of holders of Company Series A
Preferred Stock if the Series A Required Vote for the Series A
 
                                       6
<PAGE>
Amendment is not received, (A) if Special Conversion Rights are exercised, the
consideration which such holder is entitled to receive upon exercise thereof
(subject to required tax withholding) or (B) the As-If-Converted Company Merger
Consideration (subject to required tax withholding); and (iv) in the case of
holders of PacifiCare Class A Common Stock and PacifiCare Class B Common Stock,
certificates representing the number of whole shares of Holding Series A and
Holding Series B Common Stock that such holder has the right to receive pursuant
to the provisions of Section 1.5. In each case, the Old Stock Certificate so
surrendered shall be canceled. Until surrendered as contemplated by this Section
1.7 or by Section 1.5(a)(iv), each Old Stock Certificate shall be deemed, from
and after the Effective Time to represent only the right to receive upon such
surrender the consideration contemplated by Section 1.5.
 
    (d)  No dividends or other distributions declared or made with respect to
Holding Class A Common Stock, Holding Class B Common Stock or, if applicable,
Holding Series A with a record date after the Effective Time shall be paid to
the holder of any unsurrendered Old Stock Certificate with respect to the shares
of Holding Class A Common Stock, Holding Class B Common Stock and Holding Series
A represented thereby, and no cash payment shall be paid to any such holder,
until such holder surrenders such Old Stock Certificate in accordance with this
Section 1.7 (at which time such holder shall be entitled to receive all such
dividends and distributions and such cash payment).
 
    (e)  No certificates or scrip for fractional shares of Holding Class A
Common Stock, Holding Class B Common Stock or, if applicable, Holding Series A
shall be issued, but in lieu thereof, each holder of shares of Company Common
Stock or Company Series A Preferred Stock who would otherwise be entitled to
receive a certificate or scrip for a fraction of a share of Holding Class A
Common Stock, Holding Class B Common Stock or Holding Series A shall receive
from Holding a cash amount equal to the market value of one share of Holding
Class A Common Stock, Holding Class B Common Stock or Holding Series A, as the
case may be, (based on the closing sales price of one share of Holding Class A
Common Stock, Holding Class B Common Stock or Holding Series A as quoted on the
Nasdaq National Market or the New York Stock Exchange ("NYSE"), as the case may
be, on the first trading day after the Mergers become effective) multiplied by
the fraction of a share of Holding Class A Common Stock, Holding Class B Common
Stock or Holding Series A to which such holder would otherwise be entitled.
 
    (f)  Any portion of the Exchange Fund that remains undistributed to former
stockholders of the Company or PacifiCare as of the date 365 days after the date
on which the Mergers become effective shall be delivered to Holding upon demand,
and any former stockholders of the Company or PacifiCare who have not
theretofore surrendered their Old Stock Certificates in accordance with this
Section 1.7 shall thereafter look only to Holding for payment of their claims
for cash, Holding Class A Common Stock, Holding Class B Common Stock, Holding
Series A and any dividends or distributions with respect thereto.
 
    (g)  Neither PacifiCare nor the Company shall be liable to any holder or
former holder of shares of Company Common Stock, PacifiCare Common Stock or
Company Series A Preferred Stock with respect to any shares (or dividends or
distributions with respect thereto) or cash amounts from the Exchange Fund
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law.
 
    1.8  APPRAISAL RIGHTS.  Notwithstanding Section 1.5 above, shares of stock
of the Company or PacifiCare outstanding immediately prior to the Effective Time
and held by a holder who has not voted in favor of the Company Merger or the
PacifiCare Merger, as applicable, and who has exercised appraisal rights in
respect of such shares of the Company or PacifiCare in accordance with the DGCL,
shall not be converted into a right to receive shares or cash or other
consideration otherwise available to such holder (including without limitation
the Talbert Rights) unless such holder fails to perfect or withdraws or
otherwise loses his appraisal rights prior to the Effective Time. Shares of
Company's and PacifiCare's stock in respect of which appraisal rights have been
exercised shall be treated in accordance with Section 262 of the DGCL. If after
the Effective Time such holder fails to perfect or
 
                                       7
<PAGE>
withdraws or otherwise loses his right to demand payment of the fair value of
his shares under the DGCL, such shares shall be treated as if they had been
converted as of the Effective Time into a right to receive the shares and
consideration such holder would have received if such holder had not exercised
his appraisal rights; provided, however, that, such shares shall not be entitled
to a distribution of any Talbert Rights as provided in Section 4.15, but shall
be entitled to receive in cash the amount equal to the average closing price at
which such rights trade on their first five trading days. The Company shall give
PacifiCare prompt notice of any demands received by the Company for the exercise
of appraisal rights with respect to shares of the Company's Common Stock or the
Company's Series A Preferred Stock and PacifiCare shall have the right to
participate in all negotiation and proceedings with respect to such demands. The
Company shall not, except with the prior written consent of PacifiCare, make any
payment with respect to, or settle or offer to settle, any such demands.
 
    1.9  STOCK SUBJECT TO CONDITIONS.  If any shares of Company Common Stock or
PacifiCare Common Stock outstanding immediately prior to the Effective Time are
unvested or are subject to a repurchase option, risk of forfeiture or other
condition under any applicable stock purchase agreement, restriction agreement
or other agreement with the Company or PacifiCare, then (unless such condition
terminates by virtue of the applicable Merger pursuant to the express terms of
such agreement) the shares of Holding Common Stock issued in exchange for such
shares of Company Common Stock or PacifiCare Common Stock, as the case may be,
will also be unvested or subject to the same repurchase option, risk of
forfeiture or other condition, and the certificates evidencing such shares of
Holding Common Stock may accordingly be marked with appropriate legends.
 
    1.10  TAX CONSEQUENCES.  For federal income tax purposes, the Mergers are
intended to constitute contributions of property in exchange for stock within
the meaning of Section 351(a) of the Code. Neither the Company nor PacifiCare
shall take a position inconsistent with this Section 1.10 on any tax return.
 
    1.11  ACCOUNTING CONSEQUENCES.  For accounting purposes, the Company Merger
is intended to be treated as a "purchase."
 
    1.12  FURTHER ACTION.  If at any time after the Effective Time any further
action is determined by Holding to be necessary or desirable to carry out the
purposes of this Agreement or to vest the Company Surviving Corporation or
PacifiCare Surviving Corporation with the full right, title and possession of
and to all assets, property, rights, privileges, immunities, powers and
franchises of Company Sub and the Company or of Neptune Sub and PacifiCare,
respectively, the officers and directors of the applicable Surviving Corporation
shall be fully authorized (in the name of Company Sub, in the name of the
Company, in the name of Neptune Sub, or in the name of PacifiCare and otherwise)
to take such action.
 
                                   ARTICLE 2
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
    Except as set forth in the disclosure schedule delivered to PacifiCare on
the date of the Original Agreement and signed by the President of the Company
(the "Company Disclosure Schedule"), the Company represents and warrants to
PacifiCare and Holding, as of the date of the Original Agreement (except to the
extent set forth in Section 5.1(b)) as follows:
 
    2.1  ORGANIZATION; SUBSIDIARIES; CAPITALIZATION.
 
    (a)  The Company is a corporation duly organized, existing and in good
standing under the laws of the State of Delaware. The Company has all necessary
power and authority under applicable corporate law and its organizational
documents to own or lease its properties and to carry on its business as
presently conducted. As of the date of the Original Agreement, the Company
Disclosure
 
                                       8
<PAGE>
Schedule sets forth a list of all of the Company's subsidiaries. For purposes of
this Agreement, a company's "subsidiaries" shall include all corporations,
limited partnerships, joint ventures and other entities in which such company,
directly or indirectly, owns a majority interest.
 
    (b)  Each of the Company and its subsidiaries, to the extent conducting
business as a health maintenance organization ("HMO"), insurance company,
third-party administrator or otherwise requiring any form of governmental
licensure, qualification or authorization, is duly licensed, qualified or
authorized and in good standing under the applicable laws and regulations,
respectively, of each state or territory in which the conduct of such business
requires such licensure, qualification or authorization, except where failure
would not have a material adverse effect on the Company or its material
subsidiaries as set forth in Schedule 2.1(b) (the "Company's Material
Subsidiaries"). The conduct of the Company's and its subsidiaries' respective
business is in conformity with all applicable foreign, federal, state or
territorial, local and other governmental and regulatory requirements and the
forms, procedures and practices of the Company and its subsidiaries in the
conduct of their respective business are also in compliance with all such
requirements, to the extent applicable, except where nonconformity or
noncompliance would not constitute a Material Adverse Effect on the Company. For
purposes of this Agreement, "Material Adverse Effect," as it applies to the
Company, means a material adverse effect on the business, operations, financial
condition or assets of the Company and its subsidiaries, taken as a whole, other
than as a result of the performance by the Company of its obligations, or the
exercise by Holding, PacifiCare and Neptune Sub of their rights, under this
Agreement.
 
    (c)  As of the date of the Original Agreement, the authorized capital stock
of the Company consisted of: 100,000,000 shares of Company Common Stock, par
value $0.05 per share, of which, as of the date of the Original Agreement,
40,806,165 shares were issued and outstanding; and 40,000,000 shares of
preferred stock, par value $0.05 per share, of which, as of the date of the
Original Agreement, 21,030,345 shares of Company Series A Preferred Stock were
issued and outstanding. All the issued and outstanding shares of Company Common
Stock and Company Series A Preferred Stock are validly issued, fully paid and
nonassessable and free of preemptive rights. As of the date of the Original
Agreement, the Company had issued outstanding options to purchase a total of
3,917,259 shares of Company Common Stock (the "Company Options") pursuant to
Company's stock option plans and agreements. The Company has provided PacifiCare
a schedule (the "Option and Restricted Stock Schedule") which sets forth (i)
with respect to the Company Options, the name of each optionee, the number of
shares of Company Common Stock subject to each Company Option, the date of grant
and exercise price and the vesting schedule of each Company Option, (ii) each
option plan and agreement under which the Company Options have been granted, and
the Company has delivered to PacifiCare complete and accurate copies of all such
plans, and (iii) the name of each holder of restricted stock, the date of sale
and issuance of such restricted stock to each such holder, and the applicable
restrictions on such restricted stock. The Company has an Amended and Restated
Rights Agreement dated as of March 28,1994 between Company and American Stock
Transfer & Trust Co., as agent (the "Restated Rights Agreement") under which
certain shareholder rights have been granted. The execution of Voting and
Non-Disposition Agreements by certain stockholders of the Company has not and
will not give rise to any rights or benefits under the Restated Rights Plan.
Except as set forth above or on the Company Disclosure Schedule, as of the date
of the Original Agreement, (i) there were no shares of capital stock of the
Company authorized, issued or outstanding, (ii) there were no outstanding
subscriptions, options, warrants, stock appreciation right plans, calls, rights,
convertible securities, stockholder rights plans (or similar plans commonly
referred to as "poison pills") or other agreements or commitments of any
character relating to issued or unissued capital stock or other securities of
the Company or any of its subsidiaries, or obligating the Company or any other
party to issue, transfer or sell any shares of the capital stock or other
securities of the Company or any of its subsidiaries, and (iii) there were no
other outstanding securities convertible into, exchangeable for or evidencing
the right to subscribe for any shares of the capital stock or other securities
of the Company or any of its
 
                                       9
<PAGE>
subsidiaries or any successor corporation or controlling person of such
successor corporation. The Company is not under any obligation to register under
the Securities Act any of its presently outstanding securities or any securities
that may be subsequently issued.
 
    (d)  Each subsidiary of the Company is a corporation duly organized, validly
existing and in good standing under the laws of its jurisdiction of
incorporation and has all necessary power and authority under applicable
corporate law to own and lease its properties and to carry on its business as
presently conducted. All of the outstanding shares of capital stock of each
subsidiary of the Company are validly issued, fully paid and nonassessable and
are owned beneficially and of record by the Company or another subsidiary of the
Company, free and clear of any liens, claims or encumbrances.
 
    (e)  Complete and accurate copies of the Certificate of Incorporation and
Bylaws (or other or comparable charter documents), each as amended to date, of
the Company and each of its subsidiaries are filed as exhibits to the Company
SEC Reports or have been delivered to PacifiCare.
 
    2.2  SEC FILINGS; FINANCIAL STATEMENTS.
 
    (a)  The Company has made available to PacifiCare a complete and accurate
copy of each report, schedule, registration statement and definitive proxy
statement filed by the Company with the Securities and Exchange Commission
("SEC") on or after July 1, 1995 (the "Company SEC Reports"), which are all the
forms, reports and documents required to be filed by the Company with the SEC
since July 1, 1995. The Company SEC Reports (i) complied in all material
respects with the requirements of the Securities Act or the Exchange Act (as
such terms are defined in Section 2.17), as the case may be, at and as of the
times they were filed (or, if amended or superseded by a filing prior to the
date of this Agreement, then on the date of such filing) and (ii) did not at and
as of the time they were filed (or, if amended or superseded by a filing prior
to the date of this Agreement, then on the date of such filing) contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary in order to make the statements therein, in light
of the circumstances under which they were made, not misleading.
 
    (b)  Each of the sets of financial statements (including, in each case, any
related notes thereto) contained in the Company SEC Reports and the Company's
estimated balance sheet as of May 31, 1996 (the "May 31, 1996 Balance Sheet"),
as well as the Company's preliminary interim income statement for the fiscal
year ended June 30, 1996 (the "June 30 Statement") that have been delivered to
PacifiCare (collectively, the "Past Financial Statements") were prepared in
accordance with generally accepted accounting principles ("GAAP") applied on a
consistent basis throughout the periods involved (except as may be indicated in
the notes thereto) and fairly presents the consolidated financial position of
the Company and its subsidiaries as at the respective dates thereof and the
consolidated results of its operations and cash flows for the periods indicated,
except that the May 31, 1996 Balance Sheet and the June 30 Statement included in
the Past Financial Statements (i) were or are subject to normal year-end audit
adjustments which were not or are not expected to be material in amount and (ii)
do not contain footnotes.
 
    (c)  The Company and its subsidiaries have no Liabilities, except for (i)
any Liability which is accrued or fully reserved against in the May 31, 1996
Balance Sheet or disclosed in the notes included in the Past Financial
Statements, (ii) any Liability which was incurred after May 31, 1996 in the
ordinary course of business, (iii) other Liabilities which, individually or in
the aggregate, have not had and would not reasonably be expected to have a
Material Adverse Effect on the Company or (iv) any Liability under or disclosed
in this Agreement. As used herein, "Liabilities" shall mean any liability or
obligation of any kind or nature, secured or unsecured (whether absolute,
accrued, contingent or otherwise, and whether due or to become due).
 
    2.3  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Since March 31, 1996, there has
not been (a) any change, or any development or combination of changes or
developments that has had or would reasonably be expected to have a Material
Adverse Effect on the Company, (b) any damage, destruction or loss, whether or
not covered by insurance, that has had or would reasonably be expected to have a
Material Adverse Effect on the Company or (c) except as permitted or required in
this
 
                                       10
<PAGE>
Agreement, any transaction, commitment, dispute or other event or condition
(financial or otherwise) of any character (whether or not in the ordinary course
of business) which would be prohibited by Section 4.2(b)(i), (ii), (v), (vi),
(vii), (ix), (xiv), and (xvi) if it were to occur or be effected between the
date of the Original Agreement and the Effective Time.
 
    2.4  TAX MATTERS.
 
    (a)  The Company (or, if applicable, one of its subsidiaries) has filed,
within the time (including any extensions of applicable due dates) and in the
manner prescribed by law, all material returns, declaration, reports, estimates,
information returns and statements, including information returns and reports
("Returns"), required to be filed under federal, state or territorial, local or

    (c)  The Company and its subsidiaries have not filed (and will not file
prior to the Closing Date) any consent agreement under Section 341(f) of the
Code or agreed to have Section 341(f)(2) of the Code apply to any disposition of
any subsection (f) asset (as such term is defined in Section 341(f)(4) of the

    (a)  COMPANY MATERIAL CONTRACTS. For purposes of this Agreement, "Company
Material Contracts" shall mean (i) each contract, agreement or other arrangement

Company and its subsidiaries or their businesses or prospects taken as a whole;
and (iv) for each state in which the Company or its subsidiary conducts business

                                       11

    All Company Material Contracts, are in full force and effect and are binding
upon Company or its subsidiary, as the case may be, and, to the Company's
knowledge, are binding on the other parties thereto, except as enforcement
thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or
other similar laws, both state and federal, affecting the enforcement of
creditors' rights or remedies in general from time to time in effect and the
exercise by courts of equity powers. To the Company's knowledge, no material
default by the Company or any of its subsidiaries has occurred under any of the
Company Material Contracts and (A) no material default by any of the other
contracting parties has occurred under any of the Company Material Contracts,
(B) no event has occurred which with the giving of notice or the lapse of time,
or both, would constitute a material default by the Company or any of its
subsidiaries or any of the other contracting parties and (C) there is no other
reason, including without limitation any pending or threatened termination, that
any Company Material Contract will terminate (other than expiration in
accordance with its terms).

than invoices in the ordinary course of business, or claims made under risk
programs in the ordinary course of business made or, to the Company's knowledge,
threatened against the Company or any of its subsidiaries under each Company

charges, rebates, price reductions, breaches of product or service warranties or
for product or service liability for products manufactured or sold), to the
extent such claims have had or would reasonably be expected to have (i) for
provider contracts, a cost to the Company or its Material Subsidiaries in excess
of $5,000,000 or (ii) for other Company Material Contracts, a material adverse
effect on the Company or any of its Material Subsidiaries.
 
    (c)  Except as listed on the Company Disclosure Schedule, there are no
contracts, agreements or understandings, oral or written, between the Company or
any of its subsidiaries and Talbert that would interfere or conflict with the
transactions contemplated by Section 4.15 hereof.
 
    2.6  EMPLOYEES.
 
    (a)  The Company has made available to PacifiCare a list of the top 100 paid
employees of the Company and its subsidiaries and, to the Company's knowledge,
the information relating to each person on such list is correct. The Company
Disclosure Schedule identifies each "employee benefit plan," as defined in
Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), currently or previously maintained, contributed to or entered into by
the Company or any ERISA Affiliate (as defined below) under which the Company or
any ERISA Affiliate thereof has any present or future obligation or liability
(collectively, the "Company Employee Plans"). For purposes of this Section 2.6,
"ERISA Affiliate" shall mean any entity which is a member of (A) a "controlled
group of corporations," as defined in Section 414(b) of the Code, (B) a group of
entities under "common
 
                                       12
<PAGE>
control," as defined in Section 414(c) of the Code, or (C) an "affiliated
service group," as defined in Section 414(m) of the Code, or treasury
regulations promulgated under Section 414(o) of the Code, any of which includes
Company. Copies of all Company Employee Plans (and, if applicable, related trust
agreements) and all amendments thereto and written interpretations thereof
(including summary plan descriptions) have been made available to PacifiCare or
its counsel, together with the most recent annual report (Form 5500, including,
if applicable, Schedule B thereto) prepared in connection with any such Company
Employee Plan. All Company Employee Plans which individually or collectively
would constitute an "employee pension benefit plan," as defined in Section 3(2)
of ERISA (collectively, the "Company Pension Plans"), are identified as such in
the Company Disclosure Schedule. All material contributions due from the Company
with respect to any of the Company Employee Plans have been made as required
under ERISA or have been accrued on the Company's financial statements as of
March 31, 1996. Each Company Employee Plan has been maintained substantially in
compliance with its terms and with the requirements prescribed by any and all
statutes, orders, rules and regulations, including, without limitation, ERISA
and the Code, which are applicable to such Company Employee Plans, except as
would not have a Material Adverse Effect on the Company.
 
    (b)  No Company Pension Plan constitutes, or has since the enactment of
ERISA constituted, a "multiemployer plan," as defined in Section 3(37) of ERISA.
No Company Pension Plans are subject to Title IV of ERISA. No "prohibited
transaction," as defined in Section 406 of ERISA or Section 4975 of the Code,
has occurred with respect to any Company Employee Plan which is covered by Title
I of ERISA which would have a Material Adverse Effect on the Company, excluding
transactions effected pursuant to a statutory or administrative exemption.
Nothing done or omitted to be done by the Company and no transaction or holding
of any asset under or in connection with any Company Employee Plan has or will
make the Company or any officer or director of the Company subject to any
material liability under Title I of ERISA or liable for any material tax or
penalty pursuant to Sections 4972, 4975, 4976 or 4979 of the Code or Section 502
of ERISA.
 
    (c)  With respect to each Company Pension Plan that is intended to be
qualified under Section 401(a) of the Code (a "Company 401(a) Plan"), either (A)

    3.6  EMPLOYEES.
 
    (a)  "PacifiCare Employee Plan" means each "employee benefit plan," as
defined in Section 3(3) of ERISA, currently or previously maintained,
contributed to or entered into by PacifiCare or any ERISA Affiliate (as defined
below) under which PacifiCare or any ERISA Affiliate thereof has any present or
future obligation or liability. For purposes of this Section 3.6, "ERISA
Affiliate" shall mean any entity which is a member of (A) a "controlled group of
corporations," as defined in Section 414(b) of the Code, (B) a group of entities
under "common control," as defined in Section 414(c) of the Code, or (C) an
"affiliated service group," as defined in Section 414(m) of the Code, or

includes PacifiCare. All material contributions due from PacifiCare with respect
to any of the PacifiCare Employee Plans have been made as required under ERISA
or have been accrued on PacifiCare's financial statements as of June 30, 1996.
Each PacifiCare Employee Plan has been maintained substantially in compliance
with its terms and with the requirements prescribed by any and all statutes,
orders, rules and regulations, including, without limitation, ERISA and the
Code, which are applicable to such PacifiCare Employee Plans, except as would
not have a Material Adverse Effect on PacifiCare.
 
    (b)  No PacifiCare Pension Plan constitutes, or has since the enactment of
ERISA constituted, a "multiemployer plan," as defined in Section 3(37) of ERISA.
No PacifiCare Pension Plans are subject to Title IV of ERISA. No "prohibited
transaction," as defined in Section 406 of ERISA or Section 4975 of the Code,
has occurred with respect to any PacifiCare Employee Plan which is covered by
Title I of ERISA which would have a Material Adverse Effect on PacifiCare,
excluding transactions effected
 
                                       22
<PAGE>
pursuant to a statutory or administrative exemption. Nothing done or omitted to
be done by PacifiCare and no transaction or holding of any asset under or in
connection with any PacifiCare Employee Plan has or will make PacifiCare or any
officer or director of PacifiCare subject to any material liability under Title
I of ERISA or liable for any material tax or penalty pursuant to Sections 4972,
4975, 4976 or 4979 of the Code or Section 502 of ERISA.
 
    (c)  With respect to each PacifiCare Pension Plan that is intended to be
qualified under Section 401(a) of the Code (a "PacifiCare 401(a) Plan"), either
(A) a favorable determination letter has been received from the IRS as to such
qualification under the Code as in effect immediately after the Tax Reform Act
of 1986, (B) an application for a favorable determination letter is pending that
was duly filed with the IRS prior to the expiration of the time within which
retroactive amendment relating back to the effective date of such plan may be
made under Section 401(b) of the Code and regulations or IRS pronouncements
thereunder, or (C) the time provided under Section 401(b) of the Code and
regulations or IRS pronouncements thereunder for making retroactive amendments
relating back to the effective date of such plan will not expire before the date
that is sixty (60) days after the date hereof, and there is no reason to believe
that any favorable determination letter will not be received.
 
    (d)  PacifiCare has provided, or will have provided prior to the Closing (as
defined in Section 1.3), to individuals entitled thereto all required notices
and coverage pursuant to Section 4980B of the Code and COBRA, with respect to
any "qualifying event" (as defined in Section 4980B(f)(3) of the Code) occurring

Section 4980B of the Code has been incurred with respect to any current or
former employees (or their beneficiaries) of PacifiCare.

point of view, to PacifiCare and its stockholders.
 
    3.16  FINANCIAL ADVISOR.  PacifiCare represents and warrants that except for
Dillon, Read & Co., no broker, finder or investment banker is entitled to any

    3.17  ENFORCEABILITY.  Each of PacifiCare and Holding has full corporate
power and authority to execute, deliver and perform each of the Transactional
Agreements to which it is or will become a party. The execution and delivery of
said Transactional Agreements have been duly and validly authorized by the
Boards of Directors of PacifiCare and Holding, and no other corporate
proceedings on the part of PacifiCare and Holding are necessary for PacifiCare
and Holding to authorize any of the Transactional Agreements, and no such

PacifiCare and Holding enforceable against it in accordance with their terms

and the Prospectus/Proxy Statement) and laws governing insurance companies,
HMOs, third-party administrators or other businesses operated by PacifiCare or
its subsidiaries requiring licensure, qualification or authorization, there is
no requirement applicable to PacifiCare or any of its subsidiaries to make any

Governmental Authority as a condition to the lawful consummation of any of the
transactions contemplated by this Agreement, except for such filings, permits,
authorizations, consents or approvals which, if not made or obtained, would not
have a Material Adverse Effect on PacifiCare. Except as set forth in the
PacifiCare Disclosure Schedule, neither the execution and delivery of this
Agreement by PacifiCare nor the consummation by PacifiCare will (a) conflict
with, violate or result in any breach of any provision of the Certificate of
Incorporation or Bylaws (or comparable charter documents) of PacifiCare or any
of its subsidiaries, (b) result in a material default (or with notice or lapse
of time or both would result in a default) under, or materially impair the
rights of PacifiCare or any of its subsidiaries or materially alter the rights
or

the terms of this Agreement, will be duly authorized, validly issued, fully paid
and non-assessable, will be issued in compliance with applicable federal and
state securities laws and will be clear of all liens, encumbrances and adverse
claims and may be resold by Company Affiliates (as defined in Section 4.12) in

    3.20  RESERVES.  The reserves established by PacifiCare and its subsidiaries
in the PacifiCare SEC Reports, or in any financial statement or balance sheet
contained in any document filed with the SEC after the date of the Original
Agreement, for statutorily required reserves and for incurred but not yet paid
claims for, or relating to, medical treatment or similar claims (i) are computed
in accordance with presently accepted industry standards consistently applied,

used in computing the corresponding reserve in the prior fiscal year, and (iv)
include provision for all actuarial reserves and related items which ought to be
established in accordance with applicable laws or regulations and prudent
industry practices. As of the date of the Original Agreement, neither PacifiCare
nor its senior management was aware of any fact or circumstance which would
necessitate, in the good faith application of prudent reserving practices and
policies, any material adverse change in statutorily required reserves or
reserves for such incurred but not yet paid claims above that reflected in the
most recent balance sheet included in the PacifiCare SEC Reports (other than
increases consistent with past experience resulting from increases in enrollment

    3.21  AUDITS OR INVESTIGATIONS BY GOVERNMENTAL ENTITIES.  As of the date of
the Original Agreement, other than as disclosed in the PacifiCare Disclosure
Schedule, no audit or investigation of PacifiCare or any of its subsidiaries

pending before, or to PacifiCare's knowledge had been threatened by, any
governmental or regulatory authority of the United States (other than the IRS),
the several States or territories (other than state taxing authorities) or any
foreign jurisdiction. There are no pending or anticipated proceedings which may
be expected to have a Material Adverse Effect on PacifiCare by or on behalf or
in the name of the state or federal government or any governmental agency
relating to the imposition of civil monetary penalties, exclusion or debarment
from governmental programs or other administrative sanctions.
 
    3.22  ENVIRONMENTAL PROVISIONS.
 
    (a)  For the purposes of this Section 3.22, the following definitions apply.
"Environmental Claim" means any claim, action, cause of action, or written
notice by any person or entity alleging potential liability (including, without
limitation, potential liability for investigatory costs, cleanup costs,
governmental response costs, natural resources damages, property damages,
personal injuries, or penalties) resulting from (A) the presence, or release
into the environment, of any Material of Environmental Concern at any location,
whether or not owned or operated by PacifiCare or any subsidiary, or (B) any
violation, or alleged violation, of any Environmental Law. "Environmental Laws"
means all applicable federal, state or territorial, local and foreign laws and
regulations relating to pollution or protection of human health or the
environment (including, without limitation, ambient
 
                                       26
<PAGE>
air, surface water, ground water, land surface or subsurface strata), including,
without limitation, laws and regulations relating to emissions, discharges,
releases or threatened releases of Materials of Environmental Concern, or
otherwise relating to the manufacture, processing, distribution, use, treatment,
storage, disposal, transport or handling of Materials of Environmental Concern.
"Materials of Environmental Concern" means chemicals, pollutants, contaminants,
wastes, and substances that are hazardous, toxic or otherwise a danger to
health, reproduction, or the environment or are regulated by Environmental Laws.
 
    (b)  PacifiCare and each subsidiary is in compliance in all material
respects with all applicable Environmental Laws, which compliance includes, but
is not limited to, the possession by them of all material permits and other
governmental authorizations required under applicable Environmental Laws, and
compliance in all material respects with the terms and conditions thereof except
where the costs of any failure to comply will not exceed $5,000,000. PacifiCare
and its subsidiaries have not received any written communication, whether from a
Governmental Authority, citizens group, employee or otherwise, that alleges that
they are not in such full compliance in all material respects, and, to the
knowledge of PacifiCare, there are no circumstances that may prevent or
interfere with such full compliance in all material respects in the future. To
the knowledge of PacifiCare, no current or prior owner of any property owned or
leased by PacifiCare or any subsidiary has received any written communication,
whether from a Governmental Authority, citizens group, employee or otherwise,
that alleges that any of them is not in such compliance.
 
    (c)  There is no material Environmental Claim pending or, to the knowledge
of PacifiCare, threatened against PacifiCare or any subsidiary or against any
person or entity whose liability for any Environmental Claim PacifiCare has or
may have retained or assumed either contractually or by operation of law.
 
    (d)  To the knowledge of PacifiCare, there are no past or present actions,
activities, circumstances, conditions, events or incidents, including, without
limitation, the release, emission, discharge, presence or disposal of any
Material of Environmental Concern, that could reasonably form the basis for any
Environmental Claim against PacifiCare, any subsidiary or, to the knowledge of
PacifiCare, against any person or entity whose liability for any material
Environmental Claim PacifiCare or any subsidiary has or may have retained or
assumed either contractually or by operation of law, which Environmental Claim

    3.23  INTELLECTUAL PROPERTY.
 
    (a)  To the knowledge of PacifiCare, PacifiCare and its subsidiaries own or
have in their possession certain information of the sort typically considered as
trade secrets in the healthcare industry (the "Trade Secrets"). PacifiCare and
its subsidiaries have good title and an absolute (though not necessarily
exclusive) right to use all Trade Secrets, and, to the knowledge of PacifiCare,
the use of the Trade Secrets does not infringe the rights of any third party.

as currently conducted which PacifiCare or its subsidiaries do not currently own
or license on commercially reasonable terms.

issued 200 shares of Common Stock to PacifiCare in exchange for $1.00 per share;
(ii) Neptune Sub has issued 100 shares of Common Stock to Holding in exchange

the adoption of stockholder and director resolutions in connection therewith and
to authorize execution and delivery of this Agreement, adoption of the Holding

subsidiaries' Representatives, directly or indirectly, to (i) solicit, initiate
or knowingly encourage or induce the making of any Acquisition Proposal (as
defined in Section 7.1), (ii) furnish non-public information regarding the
Company or any of its subsidiaries in connection with an Acquisition Proposal or
potential Acquisition Proposal, (iii) negotiate or engage in discussions with
any third party with respect to any Acquisition Proposal, (iv) approve, endorse
or recommend any Acquisition Proposal or (v) enter into any letter of intent,
contract or other instrument related directly or indirectly to any Acquisition
Proposal (other than a nondisclosure agreement entered into in accordance with

foregoing, nothing in this Section 4.4 shall be construed to prohibit the
Company or its Board of Directors from taking any actions or permitting any
actions described above (other than any action described in clause (i) above)
with respect to any Acquisition Proposal to the extent that the Board of
Directors of the Company shall conclude in good faith, based upon the advice of
its outside counsel, that such action is required in order for the Board of
Directors of the Company to act in a manner that is consistent with its
fiduciary obligations under applicable law (PROVIDED that, in the event any
letter of intent, contract or other instrument of the type described in clause
(v) of the preceding sentence is entered into, the consummation of any
transaction contemplated by the Acquisition Proposal to which such instrument
relates must be expressly conditioned upon the prior and valid termination of
this Agreement and the payment of any fee due under Article 7 hereof).
 
    (b)  The Company shall immediately advise PacifiCare orally and in writing
of the receipt of any Acquisition Proposal or any inquiry relating to an
Acquisition Proposal prior to the Effective Time, including a full description
of the terms of such Acquisition Proposal.
 
    (c)  Notwithstanding anything to the contrary contained herein, the Company
shall not furnish any information to any third party pursuant to clause (ii) of
the first sentence of Section 4.4(a) unless
 
                                       31
<PAGE>
such third party has executed and delivered to the Company a nondisclosure
agreement that is not substantially less restrictive than the nondisclosure
agreement then in effect between the Company and PacifiCare.
 
    (d)  The Company shall immediately cease and cause to be terminated any
discussions or negotiations with any parties existing as of the date of this
Agreement and that relate to any Acquisition Proposal and shall request the
return or destruction of all information previously disclosed to such parties in
accordance with the terms of any confidentiality agreements with such parties,
and shall use commercially reasonable efforts to ensure that such information is
returned or destroyed.
 
    4.5  REGISTRATION STATEMENT; PROSPECTUS/PROXY STATEMENT.
 
    (a)  As promptly as practicable after the date of this Agreement, Holding
and PacifiCare shall prepare, with the assistance of the Company, and cause to
be filed with the SEC the S-4 Registration Statement, together with the
Prospectus/Proxy Statement and any other documents required by the Securities
Act or the Exchange Act in connection with the Mergers. Each of Holding,
PacifiCare and the Company shall use all commercially reasonable efforts to
cause the S-4 Registration Statement to comply with the rules and regulations
promulgated by the SEC, to respond promptly to any comments of the SEC or its
staff and to have the S-4 Registration Statement declared effective under the
Securities Act as promptly as practicable after such filing. The Company shall
promptly furnish to Holding and PacifiCare all information concerning the
Company, its subsidiaries and its stockholders as may be required or reasonably
requested in connection with any action contemplated by this Section 4.5. Each
of Holding, PacifiCare and the Company shall (i) notify the other promptly of
the receipt of any comments from the SEC or its staff and of any request by the
SEC or its staff for amendments or supplements to the S-4 Registration Statement
or the Prospectus/Proxy Statement or for additional information and (ii) shall
supply the other with copies of all correspondence with the SEC or its staff
with respect to the S-4 Registration Statement or the Prospectus/Proxy
Statement. Neither Holding, PacifiCare nor the Company shall file any amendment
or supplement to the S-4 Registration Statement or the Prospectus/Proxy
Statement to which the other shall have reasonably objected. Whenever any event
occurs that should be set forth in an amendment or supplement to the S-4
Registration Statement or the Prospectus/Proxy Statement, Holding, PacifiCare or
the Company, as the case may be, shall promptly inform the other of such
occurrence and shall cooperate in filing with the SEC or its staff, and, if
appropriate, mailing to stockholders of the Company and PacifiCare, such
amendment or supplement.
 
    (b)  Prior to the Effective Time, Holding shall make all required filings
with state regulatory authorities and the NASD and shall use all commercially
reasonable efforts to obtain all regulatory approvals needed to ensure that the
Holding Class A Common Stock, Holding Class B Common Stock and Holding Series A
to be issued in the Mergers (i) will be qualified under the securities or "blue
sky" law of every jurisdiction of the United States in which any registered
stockholder of the Company or PacifiCare has an address of record on the record
date for determining the stockholders entitled to notice of and to vote on the
Mergers and (ii) will be approved for quotation at the Effective Time on the
Nasdaq National Market or the NYSE.
 
    (c)  Prior to the Effective Time, Holding shall file either the Holding
Restated Certificate of Incorporation or the Holding Restated Certificate of
Incorporation without Series A, as the case may be, with the Secretary of State
of the State of Delaware.
 
    4.6  STOCKHOLDERS' MEETINGS.
 
    (a)  The Company shall take all action necessary in accordance with
applicable law to call and convene a meeting of the holders of Company Common
Stock and Company Series A Preferred Stock (the "Company Stockholders' Meeting")
to consider, act upon and vote upon the adoption and approval of this Agreement,
the Company Merger and the Series A Amendment. The Company Stockholders' Meeting
will be held within 60 days after the S-4 Registration Statement is declared
 
                                       32
<PAGE>
effective by the SEC. The Company shall ensure that the Company Stockholders'
Meeting is called, held and conducted, and that all proxies solicited in
connection with the Company Stockholders' Meeting are solicited, in compliance
with applicable law.
 
    (b)  The Board of Directors of the Company has unanimously recommended (and
the Prospectus/ Proxy Statement shall include a statement to the effect that the
Board of Directors of the Company has unanimously recommended) that the holders
of Company Common Stock and Company Series A Preferred vote in favor of and
adopt and approve this Agreement, the Company Merger and the Series A Amendment
at the Company Stockholders' Meeting and any related amendment to the Company's
Certificate of Incorporation, which unanimous recommendation shall not be
withdrawn, amended or modified in a manner adverse to PacifiCare. For purposes
of this Agreement, it shall constitute a modification adverse to PacifiCare if
such recommendation shall no longer be unanimous.
 
    (c)  PacifiCare shall take all action necessary in accordance with
applicable law to call or convene a meeting of the holders of PacifiCare Class A
Common Stock and the PacifiCare Class B Common Stock (the "PacifiCare
Stockholders' Meeting") to consider, act upon and vote upon the approval of this
Agreement, the PacifiCare Merger, the PacifiCare Amendment and any related
matters. The PacifiCare Stockholders' Meeting will be held as close to the date
of the Company Stockholders' meeting as is practicable. PacifiCare shall ensure
that the PacifiCare Stockholder's Meeting is called, held and conducted, and
that all proxies solicited in connection with such meeting are solicited, in
compliance with applicable law.
 
    (d)  The Board of Directors of PacifiCare has recommended, with no
dissenting votes (and the Prospectus/Proxy Statement shall include a statement
to the effect that the Board of Directors has so recommended) that the holders
of PacifiCare Class A Common Stock vote in favor of this Agreement, the
PacifiCare Merger, and related matters and that the holders of PacifiCare Class
A Common Stock and PacifiCare Class B Common Stock vote in favor of the
PacifiCare Amendment.
 
    (e)  Notwithstanding the foregoing, nothing in Section 4.5 or in this
Section 4.6 shall prevent the Board of Directors of the Company or PacifiCare
from withdrawing, amending or modifying its recommendation in favor of the
respective Mergers and approval and adoption of this Agreement and related
matters (and the Prospectus/Proxy Statement may reflect such withdrawal,
amendment or modification) to the extent that such Board of Directors of the
Company or PacifiCare shall conclude in good faith, based upon the advice of its
outside counsel, that such withdrawal, amendment or modification is required in
order for such Board of Directors to act in a manner that is consistent with its
fiduciary obligations under applicable law. Nothing contained in this Section
4.6(e) shall limit the Company's or PacifiCare's obligation to convene the
Company Stockholders' Meeting and the PacifiCare Stockholders' Meeting
(regardless of whether the recommendation of the Board of Directors of the
Company or PacifiCare, as the case may be, shall have been withdrawn, amended or
modified).
 
    4.7  REGULATORY APPROVALS.
 
    (a)  Holding, the Company and PacifiCare shall use all reasonable efforts to
file and to cause any stockholders of the Company or PacifiCare, as the case may
be, to file as soon as practicable after the date of this Agreement all notices,
reports and other documents required by law to be filed with any Governmental
Authority with respect to the Mergers and the other transactions contemplated by
this Agreement and to submit promptly any additional information requested by
any such Governmental Authority. Without limiting the generality of the
foregoing, Holding, the Company and PacifiCare shall within fifteen (15)
business days from the date of the Original Agreement prepare and file the
notifications required under the HSR Act in connection with the Mergers.
Holding, the Company and PacifiCare shall respond as promptly as practicable to
(i) any inquiries or requests received from the Federal Trade Commission or the
Antitrust Division of the Department of Justice for additional information or
documentation and (ii) any inquiries or requests received from any state
attorney general or other Governmental Authority in connection with antitrust or
related matters.
 
                                       33



<PAGE>
    (b)  Holding, the Company and PacifiCare shall (i) give each other prompt
notice of the commencement of any Proceeding by or before any court or
Governmental Authority with respect to the Mergers or any of the other
transactions contemplated by this Agreement, (ii) keep each other informed as to
the status of any such Proceeding and (iii) except as may be prohibited by any
Governmental Authority or by any law or court order or decree, permit the other
party to be present at each meeting or conference relating to any such
Proceeding and to have access to and be consulted in advance in connection with
any document filed or provided to any Governmental Authority in connection with
any such Proceeding.
 
    4.8  EMPLOYEE BENEFITS PLANS.
 
    (a)  At least twenty (20) days before the date of the Company Stockholders'
Meeting, PacifiCare shall notify the Company if it wishes to provide a mechanism
to cash out either vested or all outstanding Company Options. If PacifiCare
wishes to provide such a mechanism, PacifiCare shall offer (in a form reasonably
acceptable to the Company) to each holder of applicable Company Options, the
right to receive on the Effective Date, in return for the cancellation of such
option, an amount equal to (i) the product of the value of the consideration to
be received for each share of Company Common Stock covered by the cash out (with
stock values of Holding Common Stock measured by the average closing price as
quoted in the Wall Street Journal of PacifiCare's Class A Common Stock during
the twenty trading days ending the date immediately prior to the date of the
Company's Stockholder Meeting for Holding Class A Common Stock and by the
Average Pre-Vote Closing Share Price for Holding Class B Common Stock) times the
number of shares of Company Common Stock with respect to which such option is
exercisable, less (ii) the aggregate exercise price of such shares. The amount
paid to any holder of Company Options following such payment and cancellation
shall be net of applicable withholding taxes.
 
    (b)  On the Closing Date, and subject to any required approval of the
holders of Company Options, which the Company hereby covenants to exercise its
best efforts to obtain, Holding and PacifiCare will cause each Company Option to
be replaced effective as of the Effective Time, by a substitute option of
Holding (an "Exchange Option") issued under a Holding stock option plan that
complies in all respects with the applicable requirements of Rule 16b-3
promulgated under the Exchange Act. The per share exercise price of an Exchange
Option shall equal the quotient, rounding up to the nearest cent, of (i) the per
share exercise price of the corresponding Company Option, less the average
closing price at which the rights to acquire Talbert stock trade on their first
five trading days after issuance, as quoted in the Wall Street Journal, divided
by (ii) the fraction of a share of Holding Class B Common Stock that the holder
of such Company Option is entitled to purchase for each share of Company Common
Stock subject to such Company Option, as determined in the next sentence. For
each share of Company Common Stock subject to such Company Option, the Exchange
Option shall entitle the holder thereof to purchase a fraction of a share of
Holding Class B Common Stock equal to the sum of (i) the fraction of a share of
Holding Class B Common Stock into which one (1) share of Company Common Stock
actually outstanding at the Effective Time is converted pursuant to Article 1,
plus (ii) the fraction of a share of Holding Class B Common Stock that could be
purchased at the Average Pre-Vote Closing Share Price for the value of the
PacifiCare Class A Common Stock into which one (1) share of Company Common Stock
actually outstanding at the Effective Time is converted pursuant to Article 1,
which value shall be the average closing price as quoted in the Wall Street
Journal of the PacifiCare Class A Common Stock during the same trading days that
the Average Pre-Vote Closing Share Price is determined, plus (iii) the fraction
of a share of Holding Class B Common Stock that could be purchased at the
Average Pre-Vote Closing Share Price for $17.50. Any restriction on the exercise
of any Company Option shall apply to the Exchange Option and the term,
exercisability, vesting schedule and other provisions of such Company Option
shall similarly apply to the Exchange Option; provided, however, that each such
Exchange Option shall, in accordance with its terms, be subject to further
adjustment as appropriate to reflect any stock split, stock dividend,
recapitalization or other similar transaction subsequent to the Effective Time;
provided, further, that in the case of an Exchange Option of a person who is an
employee of the Company or one of its subsidiaries, such Exchange Option shall
provide that (i) any unvested shares, the vesting
 
                                       34
<PAGE>
of which depends on achievement by the Company of earnings or financial
performance of the Company for a fiscal year beginning on or after July 1, 1996,
shall instead vest no later than 25% per year over a four year period, with the
first 25% vesting on July 1, 1997 and (ii) if the holder of such Exchange Option
is terminated without cause after the Closing Date and before the date as of
which, determined as of execution of this Agreement and assuming no termination
of any employee and the application of the vesting schedule set forth in clause
(i) above, there would remain no more than 100,000 of such Exchange Options in
the aggregate that are not vested, such option shall thereupon become fully
vested; provided further that in the case of an Exchange Option of a person who
is an employee of Talbert, if the rights offering described in Section 4.15(c)
is consummated in such a manner that Talbert would no longer be considered a
subsidiary of FHP for purposes of such Exchange Option, the employment of such
person by FHP or one of its subsidiaries shall be deemed terminated for the
convenience of the Company and the accelerated vesting rights set forth in the
foregoing proviso shall not apply; further provided, that, in the case of a
holder of an Exchange Option who is a director of the Company or one of its
subsidiaries and who is not an employee of the Company or any of its
subsidiaries, the Exchange Option shall vest immediately when such holder no
longer is serving as a director of Holding or Company or one of their
subsidiaries. The Company, Holding and PacifiCare shall take such reasonable
actions, and cooperate with each other in all action, that may be necessary and
permissible to effectuate the provisions of this Section 4.8(b), including
without limitation, timely sending notice of the Company's Board of Director's
determination to suspend acceleration of vesting of Company Options issues under
the Company's Executive Incentive Plan. The provisions of this Section 4.8(b)
shall not limit in any manner PacifiCare's right to cash out the vested portion
of outstanding Company options under Section 4.8(a). To the extent required
under applicable law, the terms of the applicable Company Option plans or under
any agreement thereunder, the Company shall obtain stockholder approval of the
transactions contemplated by this Section 4.8(b) and shall use its best efforts
to obtain the consent of any optionee whose consent may be required. As soon as
practicable after the Effective Time, Holding shall file with the SEC a
registration statement on Form S-8 with respect to the shares of Holding Class B
Common Stock underlying the Exchange Options and use its reasonable best efforts
to have such registration statement declared effective under the Securities Act.
The Company may amend the employment agreements described in Schedule 2.6 of the
Company Disclosure Schedule to adjust the terms and conditions for vesting of
Company Options held by employees party to such agreements, provided the
adjusted vesting is no more favorable than acceleration upon a "Change of
Control" as defined in such agreements and does not render nondeductible to the
Company any amounts under Section 280G of the Code, and further provided any
such adjustment shall neither increase other benefits or amounts payable by the
Company nor increase the number of shares or decrease the exercise price under
any Company Option now outstanding.
 
    (c)  Either (i) the Company shall cause the Company's Employee Stock
Purchase Plan to be terminated immediately prior to the Effective Time, and such
termination shall have the effects set forth in such Plan, or (ii) prior to the
Effective Time, Holding, Company and PacifiCare shall cause each right to
purchase Company Common Stock to be replaced, effective as of the Effective
Time, by a substitute right to purchase shares of Holding Class B Common Stock
("Exchange Purchase Right") issued under a Holding Employee Stock Purchase Plan
("Holding Purchase Plan") that is intended to comply with Section 423 of the
Code. The purchase price of shares of Holding Class B Common Stock under an
Exchange Purchase Right shall be equal to 85% of the fair market value of
Holding Class B Common Stock on the first date on which shares of Holding Class
B Common Stock are purchased under the terms of the Holding Purchase Plan. The
terms and conditions of each Exchange Purchase Right shall satisfy the
requirements of Section 424(a) of the Code.
 
    (d)  As of the Effective Time and for a period of not less than one year
thereafter, except to the extent required to satisfy applicable, governing law,
Holding shall, or shall cause the Company Surviving Corporation and its
subsidiaries, to provide employee benefits other than those addressed in Section
4.8(a), 4.8(b) or 4.8(c) which are either (i) no less favorable on an aggregate
basis to the benefits provided by the Company or its subsidiaries prior to the
Effective Time or (ii) as provided to
 
                                       35
<PAGE>
similarly situated employees of PacifiCare and its subsidiaries. Thereafter, to
the extent that employees of the Company Surviving Corporation or its
subsidiaries participate in benefit plans of Holding, for purposes of
eligibility of such employees for such employee benefits, Holding agrees to
credit such employee's service with the Company or its subsidiaries for such
purposes as vesting, calculation of benefits, and eligibility to participate
and, if applicable, to waive any pre-existing condition limitations related
thereto to the extent permitted by such plans as currently in effect and
applicable law. Holding and PacifiCare shall cause the Company's and its
subsidiaries' employees to be offered the right to participate in Holding's and
its subsidiaries' stock option plans and arrangements upon substantially
consistent terms.
 
    (e)  STOCK OPTIONS OF PACIFICARE. At the Effective Time, each outstanding
option to purchase shares of PacifiCare Class B Common Stock (a "PacifiCare
Class B Option") under any of PacifiCare's stock options plans, shall be
canceled and Holding shall issue in substitution therefor an option to purchase
Holding Class B Common Stock (a "Holding Class B Substitute Option") issued
under a Holding stock option plan to be adopted by Holding prior to the
Effective Time. The exercise price and the number of shares of Holding Class B
Common Stock subject to each Holding Class B Substitute Option shall be
identical to the exercise price and the number of shares of PacifiCare Class B
Common Stock subject to the PacifiCare Class B Option that such Holding Class B
Substitute Option replaces. In compliance with Section 424(a) of the Code, each
such Holding Class B Substitute Option shall be subject to substantially all of
the other terms and conditions of PacifiCare stock option it replaces. At the
Effective Time, each outstanding option to purchase shares of PacifiCare Class A
Common Stock (a "PacifiCare Class A Option") shall be converted into an option
to purchase shares of Holding Class A Common Stock (a "Holding Class A
Substitute Option") MUTATIS MUTANDIS. The exercise price and the number of
shares of Holding Class A Common Stock subject to each Holding Class A
Substitute Option shall be identical to the exercise price and the number of
shares of PacifiCare Class A Common Stock subject to the PacifiCare Class A
Option that such Holding Class A Substitute Option replaces. In compliance with
Section 424(a) of the Code, each such Holding Class A Substitute Option shall be
subject to substantially all of the other terms and conditions of the PacifiCare
stock option it replaces.
 
    4.9  INDEMNIFICATION.
 
    (a)  With respect to actions, omissions and events occurring through the
Effective Time, all rights to indemnification existing in favor of the current
directors and officers of the Company and PacifiCare as provided in their
respective Certificates of Incorporation and indemnification agreements, each as
in effect as of the date of the Original Agreement, shall survive the Mergers
and shall be observed by Holding, PacifiCare Surviving Corporation and Company
Surviving Corporation.
 
    (b)  In addition to and without limiting Section 4.9(a), Holding shall, from
and after the Closing, to the fullest extent permitted under applicable laws,
indemnify, defend and hold harmless the current officers and directors of
PacifiCare and the Company (collectively, the "Indemnified Parties") against all
losses, expenses, claims, damages, liabilities or amounts that are paid in
settlement of (subject to Section 4.9(c)), or otherwise incurred in connection
with, any claim, action, suit, proceeding or investigation by reason of the fact
that such Indemnified Party was a director or officer of PacifiCare or the
Company prior to the Effective Time and arising out of actions, omissions and
events occurring at or prior to the Effective Time or in connection with the
Mergers and the actions taken in connection therewith (a "Claim") and shall pay
expenses in advance of the final disposition of any such Claim to each
Indemnified Party upon receipt from the Indemnified Party to whom expenses are
advanced of an undertaking reasonably satisfactory to Holding to repay such
advances if legally required to do so PROVIDED, HOWEVER, that Holding will not
be liable under this Section 4.9(b) to any Indemnified Party for any action
found by a court of competent jurisdiction to constitute a violation of law, a
breach of fiduciary duty to the Company (or any subsidiary) or wilful
misconduct.
 
    (c)  For purposes of Section 4.9(b), in the event any Claim is brought
against any Indemnified Party, Holding will be entitled to participate therein
at its own expense. In such event, the Indemnified Parties shall cooperate with
and provide all information reasonably requested by Holding. Except as
 
                                       36
<PAGE>
otherwise provided below, Holding may, at its option, assume the defense of any
Claim, with counsel reasonably satisfactory to the Indemnified Party. After
notice from Holding to the Indemnified Party of the election by PacifiCare to
assume the defense thereof, Holding will not be liable to the Indemnified Party
under Section 4.9(b) for any legal or other expenses subsequently incurred by
the Indemnified Party in connection with the defense thereof except for
reasonable costs of investigation or otherwise as provided below. The
Indemnified Party shall have the right to employ separate counsel in connection
with such Claim, but the fees and expenses of such counsel incurred after notice
from Holding of its assumption of the defense thereof shall be at the expense of
the Indemnified Party unless (i) the employment of counsel by the Indemnified
Party has been authorized by Holding, (ii) the Indemnified Party shall have
reasonably concluded that there is, under applicable standards of professional
conduct, an actual conflict between the interests of Holding and the Indemnified
Party in the conduct of the defense of such action or (iii) Holding shall not
have employed counsel to assume the defense of such action, in each of which
cases the reasonable fees and expenses of the Indemnified Party's separate
counsel shall be at the expense of Holding. In any case where the expense of
defending a Claim is to be borne by Holding, the Indemnified Parties as a group
shall be entitled to no more than one law firm (in addition to local counsel) to
represent them with respect to such Claim unless there is, under applicable
standards of professional conduct (as reasonably determined by counsel to the
Indemnified Parties), an actual conflict between the interests of any two or
more Indemnified Parties, in which event such additional counsel as may be
required by reason of such conflict may be retained by the Indemnified Parties.
 
    Holding shall not be liable to indemnify the Indemnified Party under Section
4.9(b) for any amounts paid in any settlement of any Claim if such settlement is
effected without Holding's written consent. Holding shall be permitted to settle
any Claim, except that Holding shall not settle any Claim in any manner which
would impose any non-monetary penalty or material limitation (or any monetary
penalty with respect to which the Indemnified Party is not entitled to
indemnification pursuant to Section 4.9(b)) on the Indemnified Party without the
Indemnified Party's consent.
 
    Any Indemnified Party wishing to claim indemnification under Section 4.9
upon learning of any such Claim shall promptly notify Holding (although the
failure so to notify Holding shall not relieve Holding from any liability that
Holding may have under Section 4.9, except to the extent such failure materially
prejudices Holding's position with respect to such Claim), and shall deliver to
Holding the undertaking specified in Section 4.9(b) above.
 
    (d)  Holding shall maintain in effect for a period of not less than five
years from the Effective Time the current policy of directors' and officers'
liability insurance maintained by PacifiCare and the Company, as the case may
be, with respect to matters occurring prior to the Effective Time; PROVIDED,
HOWEVER, that (i) Holding may substitute therefor policies of comparable
coverage (with carriers comparable to PacifiCare's and the Company's existing
carriers) and (ii) Holding shall not be required to pay an annual premium for
such insurance in excess of two hundred percent (200%) of the last annual
premium paid by PacifiCare or the Company, as the case may be, for such
insurance prior to the date of this Agreement (the "200% Amount"). In the event
the annual premium for such insurance exceeds the 200% Amount, Holding shall be
entitled to reduce the amount of coverage of such insurance to the amount of
coverage that can be obtained for a premium equal to the 200% Amount.
 
    (e)  In the event Holding or any of its successors or assigns (i)
consolidates with or merges into any other Person and shall not be the
continuing or surviving corporation or entity of such consolidation or merger,
or (ii) transfers or conveys all or substantially all of its properties and
assets to any Person, then, and in each such case, to the extent necessary to
effectuate the purposes of this Section 4.9, proper provision shall be made so
that the successors and assigns of Holding assume the obligations set forth in
this Section 4.9 and none of the actions described in clause (i) or (ii) shall
be taken until such provision is made.
 
                                       37

    4.10  ADDITIONAL AGREEMENTS.
 
    (a)  Subject to Section 4.10(b), Holding, PacifiCare and the Company agree
to use all commercially reasonable efforts to take, or cause to be taken, all
actions necessary to consummate the Mergers and make effective the other
transactions contemplated by this Agreement. Without limiting the generality of
the foregoing, but subject to Section 4.10(b), Holding, PacifiCare and the
Company shall use all commercially reasonable efforts to (i) obtain the consent
and approval of each Governmental Authority, lessor or other person whose
consent or approval is required (by virtue of any contractual provision or legal
requirement or otherwise) in order to permit the consummation of the Merger or
any of the other transactions contemplated by this Agreement or in order to
enable Holding, PacifiCare Surviving Corporation and Company Surviving
Corporation to conduct their respective businesses in the manner in which such
business is currently being conducted or is proposed to be conducted, (ii)
effect all registrations and filings necessary to consummate the Mergers and
(iii) lift any restraint, injunction or other legal bar to the Mergers.
 
    (b)  Notwithstanding anything to the contrary contained in Section 4.10(a)
or elsewhere in this Agreement, (i) Holding shall not have any obligation under
this Agreement to dispose or cause any of its subsidiaries to dispose of any
material assets, (ii) Holding shall not have any obligation to make any changes
to its operations or proposed operations or to the operations or proposed
operations of any of its subsidiaries and (iii) Holding shall not have any
obligation to make any commitment (to any Governmental Authority or otherwise)
regarding its future operations, or the future operations of any of its
subsidiaries, or the future operations of PacifiCare Surviving Corporation or
the Company Surviving Corporation or any of their respective Material
Subsidiaries which would, in each of case (ii) and (iii) above, have a material
adverse effect thereon (even though the disposition of such assets or the making
of such change or commitment might facilitate the obtaining of a required
approval from a Governmental Authority or might otherwise facilitate the
consummation of the Mergers).
 
    4.11  DISCLOSURE.  PacifiCare and the Company will (i) mutually agree on the
text of any press release and (ii) consult with each other before making any
other public statement with respect to this Agreement and the transactions
contemplated by this Agreement, except, in each such case, as may be required by
applicable law (including disclosure requirements) or any listing or similar
agreement with any national securities exchange or the Nasdaq National Market.
 
    4.12  AFFILIATE AGREEMENTS.  The Company shall deliver to PacifiCare, within
ten days after the date of this Agreement, a letter from the Company identifying
all persons who may be "affiliates" of the Company as that term is used in
paragraphs (c) and (d) of Rule 145 under the Securities Act ("Company
Affiliates"). The Company shall use all commercially reasonable efforts to cause
each person who is or becomes a Company Affiliate to execute and deliver to
PacifiCare, on or prior to the date of the mailing of the Prospectus/Proxy
Statement, an Affiliate Agreement in the form attached hereto as Exhibit 4.12.
PacifiCare shall use all commercially reasonable efforts to cause each person
who is or becomes an affiliate of PacifiCare to execute and deliver a similar
agreement on or prior to such date.
 
    4.13  TAX QUALIFICATION AND OPINION BACK-UP CERTIFICATES.  Each of Holding,
the Company and PacifiCare will use its reasonable best efforts to cause the
transactions contemplated by this Agreement, other than the transactions with
respect to Talbert contemplated by Section 4.15 hereof, to qualify as transfers
subject to the provisions of Section 351(a) of the Code and to deliver, in
connection with the tax opinions referred to in Sections 5.9 and 6.8,
certificates of representation reasonable under the circumstances ("Tax
Certificates").
 
    4.14  FINANCING.  PacifiCare has received from Bank of America NT&SA a
commitment letter dated August 2, 1996 (the "Commitment Letter") containing its
commitment, subject to the terms and conditions thereof, to provide sufficient
financing to permit PacifiCare and Holding to consummate the transactions
contemplated hereby. A true and accurate copy of the Commitment Letter has
 
                                       38
<PAGE>
been provided to the Company. PacifiCare and Holding shall enter into the
definitive credit agreements contemplated by the Commitment Letter (or any
revised commitment letter more favorable to PacifiCare and Holding) prior to the
date on which the Proxy/Prospectus is mailed to the Company's Stockholders.
 
    4.15  TALBERT.
 
    (a)  The Company shall negotiate a written agreement with Talbert under
which all Talbert contracted medical providers or sites agree to provide
professional services to members of HMOs and enrollees in insurance products of
the Company and Company Surviving Corporation and their subsidiaries in exchange
for a current market rate capitation payment ("Capitated Contract"). The
Capitated Contract shall be subject to the review and approval of PacifiCare
prior to execution. In addition to the Capitated Contract, the Company and
Talbert shall enter into an agreement for the Company to render administrative
services (information systems, payroll, accounts payable, employee benefits
administration and the like) for a period not to exceed one year following the
Effective Date at a rate and on other terms approved by PacifiCare. PacifiCare
shall negotiate in good faith with the Company and Talbert in determining
whether to give its approval.
 
    (b)  Following execution of the Capitated Contract, the Company shall
capitalize Talbert to increase its net worth to approximately $60,000,000
("Capital Contribution"); provided, however, that in all events the net worth of
Talbert shall be equal to the proceeds of the rights offering referred to in
Section 4.15(c) below, assuming all such rights are exercised.
 
    (c)  Following the Capital Contribution, simultaneous with consummation of
the Mergers, Holding shall cause the issuance of rights to all holders of
Company Common Stock and Company Series A Preferred Stock outstanding
immediately prior to the Effective Time (other than holders who have perfected
appraisal rights in accordance with Section 1.8) and allocated among them on a
Company common share equivalent basis, exercisable until the first business day
on or after the thirtieth day after the date of the Effective Time and expiring
thereafter, to purchase, directly or indirectly through one or more other
corporations formed to facilitate such purchase all of Company's interest in
Talbert. In connection with the purchase, Holding, PacifiCare, the Company and
Talbert shall discuss the possibility of a Code section 338(h)(10) election in
connection with such purchase; provided however, that no such election shall be
made without the prior written consent of PacifiCare, which consent shall not be
withheld unless there is an adverse impact to PacifiCare.
 
    (d)  Before the Effective Time and with the prior consent of PacifiCare as
to significant actions, the Company and Talbert shall take such steps as are
reasonably required to consummate the separation of Talbert from the Company.
The Company and Talbert shall have the right to continue to prosecute the
application now pending before the California Department of Corporations for the
issuance of stock options to employees of Talbert and to carry out transactions
consistent with such application as permitted by Section 4.2(b) if and when a
permit is granted pursuant thereto.
 
    (e)  The Company will not assign any of its rights under that certain Stock
Purchase Agreement dated as of March 15, 1996 by and between the Company,
Talbert Medical Management Corporation, Talbert Health Services Corporation and
certain management investors, as amended (the "Talbert Stock Purchase
Agreement"). From and after the Effective Time, Holding will cause the committee
of the Company that makes the determinations required by Section 5.3 of the
Talbert Stock Purchase Agreement to consist of the members of the Compensation
Committee of Holding and one member of the Board of Directors of Talbert,
designated by the Board of Directors of Talbert and reasonably acceptable to the
Board of Directors of Holding.
 
    4.16  7% SENIOR NOTES DUE 2003.  Holding shall, in accordance with the terms
of the Company's 7% Senior Notes Due 2003 (the "Senior Notes"), assume the
Senior Notes.

<PAGE>
    4.17  NOTICES OF CERTAIN EVENTS.  Each of Holding, the Company and
PacifiCare shall promptly notify the other of:
 
    (a)  any notice or other communication from any Person alleging that the
consent of such Person is or may be required in connection with the transactions
contemplated by this Agreement;
 
    (b)  any notice or other communication from any governmental body, agency,
official or authority in connection with the transactions contemplated by this
Agreement that indicates such body, agency, official or authority intends to
take action that would prevent or materially interfere with the transactions
contemplated by this Agreement; and
 
    (c)  any actions, suits, claims, investigations, proceedings or health or
insurance related proceedings or market conduct examinations or audits commenced
or, to the best of Company's or PacifiCare's knowledge (as the case may be)
threatened against, relating to or involving or otherwise affecting the Company
or PacifiCare or any of their subsidiaries which, if pending on the date of this
Agreement, would have been required to have been disclosed pursuant to Section
2.7 or 3.7 or which relate to the consummation of the transactions contemplated
by this Agreement.
 
    4.18  CERTAIN CORPORATE MATTERS WITH RESPECT TO PACIFICARE.
 
    (a)  PacifiCare shall cause Holding to take all necessary corporate action
for the establishment of the Holding stock option plans contemplated by Section
4.8 hereof and agrees to vote the shares of capital stock of Holding owned by it
in favor of the adoption of such plans as required under the laws of the State
of Delaware.
 
    (b)  From the date hereof until the Effective Time, PacifiCare shall cause
Holding (x) not to take any action inconsistent with the provisions of this
Agreement and (y) not to conduct business or activity other than in connection

    4.19  COMPLIANCE WITH REGULATIONS.  PacifiCare and the Company will each use
reasonable commercial efforts, and will cause their subsidiaries to use
reasonable commercial efforts, to comply with applicable rules and regulations
of the Health Care Financing Administration relating to so-called physician
incentive plans.
 
    4.20  ASSUMPTION BY SUCCESSOR.  Holding, effective as of the Effective Time,
assumes expressly and agrees to perform the employment agreements described in
Schedule 2.6 of the Company Disclosure Schedule in the same manner and to the
same extent that the Company would be required to perform them.
 
    4.21  NO ACTIVITY BY HOLDING.  From the date of the Original Agreement until
the Effective Time, PacifiCare shall not cause or permit Holding, Neptune Sub or
Company Sub to (i) issue any stock or securities or (ii) acquire any property,
incur any liabilities or engage in any business or activity whatsoever, other
than to consummate the Mergers and transactions contemplated hereby (including
the financing thereof) and to carry out its obligations hereunder.

<PAGE>
except that any inaccuracies in such representations and warranties will be
disregarded if the circumstances giving rise to such inaccuracies (considered
individually and collectively) do not constitute, and would not reasonably be
expected to result in, a Material Adverse Effect on the Company (it being
understood that, for purposes of determining the accuracy of such
representations and warranties, (i) all Material Adverse Effect qualifications
shall be disregarded and (ii) any update of or modification to the Company

                            TERMINATION OF AGREEMENT
 
    7.1  TERMINATION.  This Agreement may be terminated prior to the Closing
Date, whether before or after approval of the Mergers by the stockholders of the
Company and PacifiCare:
 
    (a)  by mutual written consent of the respective Boards of Directors of
PacifiCare and the Company;
 
    (b)  by either PacifiCare or the Company if either of the Mergers shall not
have been consummated by April 30, 1997 (unless the failure to consummate such
Merger is attributable to a failure on the part of the party seeking to
terminate this Agreement to perform any material obligation required
to be performed by such party at or prior to the Effective Time);
 
    (c)  by either PacifiCare or the Company if a court of competent
jurisdiction or Governmental Authority shall have issued a final and
nonappealable order, decree or ruling, or shall have taken any other action,
having the effect of permanently restraining, enjoining or otherwise prohibiting
either of the Mergers;
 
    (d)  by either PacifiCare or the Company if (i) the Company Stockholders'
Meeting shall have been held and (ii) this Agreement and the Company Merger
shall not have been adopted and approved at such meeting by the Company Required
Vote;
 
    (e)  by PacifiCare (at any time prior to the adoption and approval of this
Agreement and the Company Merger by stockholders of the Company by the Company
Required Vote) if a Triggering Event (as defined below) shall have occurred;
 
    (f)  by either PacifiCare or the Company if (i) the PacifiCare Stockholders'
Meeting shall have been held and (ii) this Agreement, the PacifiCare Merger and
any related matters shall not have been adopted and approved at such meeting by
the Required PacifiCare Vote;
 
    (g)  by PacifiCare if any of the Company's representations and warranties
contained in this Agreement shall be or shall have become materially inaccurate
as of the date of the Original Agreement, or if any of the Company's covenants
contained in this Agreement shall have been breached in any material respect;
PROVIDED, HOWEVER, that if an inaccuracy in the Company's representations and
warranties or a breach of a covenant by the Company is curable by the Company
and the Company is continuing to exercise all commercially reasonable efforts to
cure such inaccuracy or breach, then PacifiCare may not terminate this Agreement
under this Section 7.1(g) on account of such inaccuracy or breach; or
 
    (h)  by the Company if any of PacifiCare's or Holding's representations and
warranties contained in this Agreement shall be or shall have become materially
inaccurate as of the date of the Original Agreement, or if any of PacifiCare's
or Holding's covenants contained in this Agreement shall have been breached in
any material respect; PROVIDED, HOWEVER, that if an inaccuracy in PacifiCare's
or Holding's representations and warranties or a breach of a covenant by
PacifiCare or Holding is curable by PacifiCare or Holding and PacifiCare or
Holding is continuing to exercise all commercially reasonable efforts to cure
such inaccuracy or breach, then the Company may not terminate this Agreement
under this Section 7.1(h) on account of such inaccuracy or breach.
 
    A "Triggering Event" shall be deemed to have occurred if (i) the Board of
Directors of the Company shall have failed to recommend, shall for any reason
have withdrawn or shall have amended or modified in a manner adverse to
PacifiCare its unanimous recommendation in favor of the Company Merger or
approval or adoption of this Agreement, or the Company shall have failed to
include in the Prospectus/Proxy Statement the unanimous recommendation of the
Board of Directors of the Company in favor of the Company Merger and approval
and adoption of this Agreement and related matters; (ii) the Board of Directors
of the Company shall have approved, endorsed or recommended any Acquisition
Proposal; (iii) the Company shall have entered into any letter of intent,
contract or
 
                                       44
<PAGE>
other instrument related directly or indirectly to any Acquisition Proposal
(other than a nondisclosure agreement entered into in accordance with Section
4.4(c) or contracts with advisors or consultants); or (iv) the Company shall
have failed to hold the Company Stockholders' Meeting within 60 days after the
S-4 Registration Statement is declared effective and any Acquisition Proposal
shall have been made during such 60-day period.
 
    "Acquisition Proposal" shall mean any proposal (other than any proposal by
PacifiCare or Neptune Sub or in connection with the transactions contemplated in
Section 4.15 regarding Talbert) regarding (i) any merger, consolidation, share
exchange, business combination or other similar transaction or series of related
transactions involving the Company; (ii) any sale, lease, exchange, transfer or
other disposition of the assets of the Company or any subsidiary of the Company
constituting more than 50% of the consolidated assets of the Company or
accounting for more than 50% of the consolidated revenues of the Company in any
one transaction or in a series of related transactions; and (iii) any offer to
purchase, tender offer, exchange offer or any similar transaction or series of
related transactions made by any Person involving more than 50% of the
outstanding shares of the capital stock of the Company or the filing of any
Statement on Schedule 14D-1 with the SEC in connection therewith.
 
    7.2  EFFECT OF TERMINATION.  In the event of the termination of this
Agreement as provided in Section 7.1, this Agreement shall be of no further
force or effect; PROVIDED, HOWEVER, that (i) this Section 7.2, Section 7.3 and
Article 8 shall survive the termination of this Agreement and shall remain in
full force and effect, (ii) such termination shall have no effect on the
Confidentiality Agreement dated July 22, 1996 between PacifiCare and the Company
which shall remain in full force and effect and, (iii) subject to Section 7.3(b)
and 7.3(c) below, the termination of this Agreement shall not relieve any party
from any liability for any breach of this Agreement.
 
    7.3  FEES AND EXPENSES.
 
    (a)  Except as set forth in this Section 7.3, all fees and expenses incurred
in connection with this Agreement and the transactions contemplated by this
Agreement shall be paid by the party incurring such expenses, whether or not the
Mergers are consummated.
 
    (b)  In consideration of the substantial time, expense and forgoing of other
opportunities that PacifiCare and Holding have invested in the transactions
contemplated hereby:
 
        (i) If this Agreement is terminated pursuant to Section 7.1(d) at any
    time after the occurrence of a Triggering Event or if this Agreement is
    terminated by PacifiCare pursuant to Section 7.1(e), then the Company shall
    pay to PacifiCare a fee, in immediately available funds, of $50,000,000 (the
    "Termination Amount"). In the case of termination of this Agreement by the
    Company pursuant to Section 7.1(d), the Termination Amount shall be paid
    prior to such termination, and in the case of termination of this Agreement
    pursuant to Section 7.1(e) or by PacifiCare pursuant to Section 7.1(d), the
    Termination Amount shall be paid within one business day of such
    termination. If the Company fails to pay such fee by the date provided
    herein, in addition to any other remedies that may be available to
    PacifiCare for such breach by the Company, said fee shall bear interest at
    the lower of 10% per annum and the maximum rate allowable by law from the
    date such payment was due until the date such fee is actually paid.
 
        (ii) If this Agreement is terminated pursuant to Section 7.1(d) (and
    Section 7.3(b)(i) is not applicable) and within 12 months of the date of the
    Company Stockholders' Meeting the Company enters into an agreement relating
    to an Acquisition Proposal, the Company shall pay to PacifiCare, within one
    business day of entering into such agreement, a fee in immediately available
    funds, of the Termination Amount. If the Company fails to pay such fee by
    the date provided herein, in addition to any other remedies that may be
    available to PacifiCare for such breach by the Company, said fee shall bear
    interest at the lower of 10% per annum and the maximum rate allowable by law
    from the date such payment was due until the date such fee is actually paid.
 
                                       45
<PAGE>
    (c)  In consideration of the substantial time, expense and forgoing of other
opportunities that the Company has invested in the transactions contemplated
hereby if this Agreement is terminated pursuant to Section 7.1(f) or if the
Mergers are not consummated solely by reason of a breach by PacifiCare caused by
its failure to enter into definitive agreements related to the financing
contemplated by the Commitment Letter, or the termination of such agreements or
the failure of PacifiCare to receive the funding contemplated by the Commitment
Letter, and after diligent efforts to find commercially reasonable alternative
financing (a "Financing Breach"), then PacifiCare shall pay the Company a fee,
in immediately available funds, of $50,000,000, in the case of a termination
pursuant to Section 7.1(f) or $100,000,000 in the case of a Financing Breach. In
the case of a termination by PacifiCare pursuant to Section 7.1(f), the
Termination Amount shall be paid upon termination. In the case of a termination
by the Company pursuant to Section 7.1(f) or the failure to consummate the
transactions contemplated hereby solely because of a Financing Breach,
PacifiCare shall pay the Termination Amount promptly following such event.
 
    If PacifiCare fails to pay such fee by the date provided, in addition to
such other remedies as may be available to the Company for such breach by
PacifiCare, said fee shall bear interest on such fee at the lower of 10% per
annum and the maximum rate allowable by law from the date such fee was due until
the date it was actually paid.
 
    (d)  Each of PacifiCare and the Company acknowledge that the fees payable
pursuant to Sections 7.3(b) and 7.3(c) (and, if applicable, any interest thereon
and attorneys' fees and costs related to any suit to enforce such provisions)
are the sole remedies of such parties for termination or failure to consummate
the Mergers under the circumstances described in such sections (other than any
willful breach of any agreement or covenant set forth in this Agreement).
 
                                   ARTICLE 8
                                 MISCELLANEOUS
 
    8.1  AMENDMENT.  This Agreement may be amended with the approval of the
respective Boards of Directors of Holding, the Company and PacifiCare at any
time before or after approval of this Agreement by the stockholders of the
Company and the stockholders of PacifiCare; PROVIDED, HOWEVER, that after any
such stockholder approval, no amendment shall be made which would have a
material adverse effect on the stockholders of the Company or the stockholders
of PacifiCare without the further approval of such stockholders. This Agreement
may not be amended except by an instrument in writing signed on behalf of each
of the parties hereto.
 
    8.2  WAIVER.
 
    (a)  No failure on the part of any party to exercise any power, right,
privilege or remedy under this Agreement, and no delay on the part of any party
in exercising any power, right, privilege or remedy under this Agreement, shall
operate as a waiver of such power, right, privilege or remedy; and no single or
partial exercise of any such power, right, privilege or remedy shall preclude
any other or further exercise thereof or of any other power, right, privilege or
remedy.
 
    (b)  No party shall be deemed to have waived any claim arising out of this
Agreement, or any power, right, privilege or remedy under this Agreement, unless
the waiver of such claim, power, right, privilege or remedy is expressly set
forth in a written instrument duly executed and delivered on behalf of such
party; and any such waiver shall not be applicable or have any effect except in
the specific instance in which it is given.
 
    8.3  NO SURVIVAL OF REPRESENTATIONS AND WARRANTIES.  None of the
representations and warranties contained in this Agreement or in any instrument
delivered pursuant to this Agreement shall survive the Mergers.
 
    8.4  ENTIRE AGREEMENT; COUNTERPARTS; APPLICABLE LAW.  This Agreement and the
other agreements referred to herein and the Confidentiality Agreement dated as
of July 22, 1996 between PacifiCare and the Company constitute the entire
agreement and supersede all prior agreements and
 
                                       46
<PAGE>
understandings, both written and oral, among or between any of the parties with
respect to the subject matter hereof. This Agreement may be executed in several
counterparts, each of which shall be deemed an original and all of which shall
constitute one and the same instrument, and shall be governed in all respects by
the laws of the State of Delaware without regard to its conflicts of laws
principles.
 
    8.5  ATTORNEYS' FEES.  In any action at law or suit in equity to enforce
this Agreement or the rights of any of the parties hereunder, the prevailing
party in such action or suit shall be entitled to receive a reasonable sum for

action or suit.
 
    8.6  ASSIGNABILITY.  This Agreement shall be binding upon, and shall be
enforceable by and inure solely to the benefit of, the parties hereto and their
respective successors; PROVIDED, HOWEVER, that this Agreement may not be
assigned by any party without the prior written consent of the other parties,
and any attempted assignment without such consent shall be void and of no
effect. Nothing in this Agreement, express or implied, is intended to or shall
confer upon any person except the parties hereto and their respective successors
any right, benefit or remedy of any nature whatsoever under or by reason of this
Agreement.
 
    8.7  NOTICES.  All notices and other communications pursuant to this
Agreement shall be in writing and shall be deemed given if delivered personally,

"Class B Common Shares," and "Preferred Shares." The total number of shares of
stock which the Corporation shall have authority to issue is two hundred forty

Certificate of Incorporation, as amended, and subject to the powers, preferences
and rights of the holders of Preferred Shares, as provided in or as otherwise

    1.  DIVIDENDS.  Dividends may be declared and paid to the holders of the
Class A Common Shares and the Class B Common Shares in cash, property, or other
securities of the Corporation out of any funds legally available therefore. If
and when dividends on the Class A Common Shares and the Class B Common Shares
are declared payable from time to time by the Board of Directors, whether
payable in cash, in property or in securities of the Corporation, the holders of
the Class A Common Shares and the holders of the Class B Common Shares shall be
entitled to share equally, on a per share basis, in such dividends, except that,
dividends or other distributions payable on the Common Shares in Common Shares
shall be made to all holders of Common Shares and may be made (i) in Class B
Common Shares to the record holders of Class A Common Shares and to the record
holders of Class B Common Shares, (ii) in Class A Common Shares to the record
holders of Class A Common Shares and in Class B Common Shares to the record

<PAGE>
    2.  DISTRIBUTION ON DISSOLUTION, ETC.  Upon any liquidation, dissolution or
winding up of the Corporation, whether voluntary or involuntary, the remaining
net assets of the Corporation shall, after payment in full of the liquidation
preference, if any, of any outstanding Preferred Shares, be distributed pro rata
to the holders of the Class A Common Shares and the Class B Common Shares in
accordance with their respective rights and interests.
 
    3.  VOTING RIGHTS.
 
    (a) At each annual or special meeting of the shareholders, each holder of
Class A Common Shares shall be entitled to one (1) vote in person or by proxy
for each Class A Common Share standing in his name on the stock transfer records
of the corporation in connection with the election of directors and all other
actions submitted to a vote of shareholders; holders of Class B Common Shares
shall not vote on any matters except as otherwise provided by this Certificate
of Incorporation, as amended, and the Delaware General Corporation Law.
 
    (b) The holders of Class B Common Shares shall be entitled to vote
separately as a group only with respect to (i) proposals to change the par value
of the Class B Common Shares, (ii) amendments to this Certificate of
Incorporation that alter or change the powers, preference or special rights of
the holders of Class B Common Shares so as to affect them adversely, and (iii)
such other matters as may require separate group voting under this Certificate
of Incorporation, as amended, and the Delaware General Corporation Law.
 
    (c) The number of authorized Class B Common Shares may be increased or
decreased (but not below the number of shares then outstanding) by the
affirmative vote of the holders of a majority of the Class A Common Shares.
 
    4.  CONVERSION.
 
    (a) All outstanding Class B Common Shares may be converted into Class A
Common Shares on a share-for-share basis by the Board of Directors if, as a
result of the existence of the Class B Common Shares, either the Class A Common
Shares or Class B Common Shares is or both are excluded from trading on the New
York Stock Exchange, the American Stock Exchange and all other principal
national securities exchanges then in use and also is excluded from quotation on
the National Association of Securities Dealers Automated Quotation ("Nasdaq")
National Market and other comparable national quotation systems then in use. In
making such determination, the Board of Directors may conclusively rely on any
information or documentation available to it, including filings made with the
Securities and Exchange Commission, any stock exchange, the National Association
of Securities Dealers, Inc. or any other governmental or regulatory agency or
any written instrument purporting to be authentic.
 
    (b) All outstanding Class B Common Shares shall be converted into Class A
Common Shares on a share-for-share basis if at any time the number of
outstanding Class A Common Shares, as reflected on the stock transfer records of
the Corporation, falls below ten percent (10%) of the aggregate number of
outstanding Class A Common Shares and of Class B Common Shares. For purposes of
the immediately preceding sentence, any Common Shares repurchased and held as
treasury shares or canceled by the Corporation shall no longer be deemed
"outstanding" from and after the date of repurchase.
 
    (c) In the event of any conversion of the Class B Common Shares pursuant to
subparagraph 4(a) or 4(b), certificates which formerly represented outstanding
shares of Class B Common Shares will thereafter be deemed to represent a like
number of shares of Class A Common shares and all authorized Common Shares shall
consist of only Class A Common Shares.
 
    5.  CLASS B COMMON SHARE PROTECTION PROVISION.
 
    (a) If, after the effective time (the "Effective Time") of the PacifiCare
Merger (the "PacifiCare Merger"), as that term is defined in the Amended and
Restated Agreement and Plan of Reorganization dated as of September 17, 1996,
among PacifiCare Health Systems, Inc., N-T Holdings, Inc., Neptune Merger Corp.,
Tree Acquisition Corp. and FHP International Corporation, as amended (the
 
                                       2
<PAGE>
"Reorganization Agreement"), any person or group acting in concert acquires
beneficial ownership of shares representing 10% or more of the then issued and
outstanding Class A Common Shares (excluding the number of shares beneficially
owned by such person or group at or before the Effective Time and other than
upon the issuance or sale by the Corporation, by operation of law, including a
merger, consolidation or reorganization of a beneficial owner, by will or the
laws of descent and distribution, by gift or by foreclosure of a bona fide
loan), and such person or group (a "Significant Shareholder") does not own an
equal or greater percentage of the Class B Common Shares acquired after the
Effective Time, such Significant Shareholder must, within a ninety (90) day
period beginning the day after becoming a Significant Shareholder, make a public
cash tender offer in compliance with all applicable laws and regulations to
acquire additional Class B Common Shares as provided in this subparagraph B (5)
of Article IV (a "Class B Protection Transaction").
 
    (b) In each Class B Protection Transaction, the Significant Shareholder must
make a public tender offer to acquire that number of Class B Common Shares
determined by (i) multiplying the percentage of outstanding Class A Common
Shares beneficially owned by such Significant Shareholder and acquired after the
Effective Time by such Significant Shareholder by the total number of shares of
Class B Common Shares outstanding on the date such person or group became a
Significant Shareholder, and (ii) subtracting therefrom the total number of
shares of Class B Common Shares beneficially owned on such date and acquired
after the Effective Time by such Significant Shareholder (including shares
acquired on such date at or prior to the time such person or group became a
Significant Shareholder). The Significant Shareholder must acquire all of such
shares validly tendered; provided, however, that if the number of Class B Common
Shares tendered to the Significant Shareholder exceeds the number of shares
required to be acquired pursuant to the formula set forth in this subparagraph
5(b), the number of Class B Common Shares acquired from each tendering holder
shall be pro rata in proportion to the total number of Class B Common Shares
tendered by all tendering holders.
 
    (c) The offer price for any Class B Common Shares required to be purchased
by the Significant Shareholder pursuant to this subparagraph B(5) shall be the
greater of (i) the highest price per share paid by the Significant Shareholder
for any Class A Common Share in the six month period ending on the date such
person or group became a Significant Shareholder or (ii) the highest bid price
of a Class A Common Share or Class B Common Share on the Nasdaq National Market
(or such other exchange or quotation system as is then the principal trading
market for such shares) on the date such person or group became a Significant
Shareholder or (iii) the highest bid price of a Class A Common Share or Class B
Common Share on the Nasdaq National Market (or such other exchange or quotation
system as is then the principal trading market for such shares) on the date
preceding the date the Significant Shareholder makes the tender offer required
by this subparagraph B(5). For purposes of subparagraph B(5)(d) below, the
applicable date for the calculations required by clauses (i) and (ii) of the
preceding sentence shall be the date on which the Significant Shareholder
becomes required to engage in a Class B Protection Transaction. In the event
that the Significant Shareholder has acquired Class A Common Shares in the six
month period ending on the date such person or group becomes a Significant
Shareholder for consideration other than cash, the value of such consideration
per Class A Common Share shall be as determined in good faith by the Board of
Directors.
 
    (d) A Class B Protection Transaction shall also be required to be effected
by any Significant Shareholder each time that the Significant Shareholder
acquires beneficial ownership of the next higher integral multiple of 5% (e.g.,
15%, 20%, 25%, etc.) of the outstanding Class A Common Shares after the
Effective Time (other than upon the issuance or sale by the Corporation, by
operation of law, including a merger, consolidation or reorganization of a
beneficial owner, by will or the laws of descent and distribution, by gift, or
by foreclosure of a bona fide loan) if such Significant Shareholder does not
then own an equal or greater percentage of the Class B Common Shares acquired
after the Effective Time. Such Significant Shareholder shall be required to make
a public tender offer to acquire that
 
                                       3
<PAGE>
number of Class B Common Shares prescribed by the formula set forth in
subparagraph B(5)(b) above, and must acquire all shares validly tendered or a
pro rata portion thereof, as specified in subparagraph B(5)(b), at the price
determined pursuant to subparagraph B(5)(c) above.
 
    (e) If any Significant Shareholder fails to make an offer required by this
subparagraph B(5) of Article IV, or to purchase shares validly tendered and not
withdrawn (after proration, if any), such Significant Shareholder shall not be
entitled to vote any Class A Common Shares beneficially owned by such
Significant Shareholder unless and until such requirements are complied with or
unless and until all Class A Common Shares causing such offer requirement to be
effective are no longer beneficially owned by such Significant Shareholder.
 
    (f) The Class B Protection Transaction requirement shall not apply to any
increase in percentage ownership of Class A Common Shares resulting solely from
a change in the total amount of Class A Common Shares outstanding, provided that
any acquisition after such change which resulted in any person or group owning
10% or more of the Class A Common Shares (excluding in the case of the numerator
but not the denominator of the calculation of such percentage, Class A Common
Shares held by such Significant Shareholder immediately after the Effective
Time) shall be subject to any Class B Protection Transaction requirement that
would be imposed with respect to a Significant Shareholder pursuant to this
subparagraph B(5) of Article IV.
 
    (g) All calculations with respect to percentage ownership of issued and
outstanding shares of either class of Common Shares will be based upon the
numbers of issued and outstanding shares reported by the Corporation on the last
to be filed of (i) the Corporation's most recent annual report on Form 10-K,
(ii) its most recent Quarterly Report on Form 10-Q, or (iii) its most recent
Current Report on Form 8-K.
 
    (h) For purposes of this subparagraph B(5) of this Article IV, the term
"person means a natural person, corporation, partnership, trust, association,
government, or political subdivision, agency or instrumentality of a government,
or other entity. "Beneficial ownership" shall be determined pursuant to Rule
13d-3 promulgated under the Securities Exchange Act of 1934, as amended (the
"1934 Act"), or any successor regulation. The formation or existence of a
"group" shall be determined pursuant to Rule 13d-5(b) under the 1934 Act or any
successor regulation.
 
    6.  MERGER OR CONSOLIDATION.  In the event of a merger or consolidation of
the Corporation with or into another entity (whether or not the Corporation is
the surviving entity), the holders of Class B Common Shares shall be entitled to
receive the same per share consideration as the per share consideration, if any,
received by any holder of the Class A Common Shares in such merger or
consolidation; provided, however, that this restriction shall not apply to the
PacifiCare Merger.
 
    7.  SPLITS, SUBDIVISIONS, ETC.  If the Corporation shall in any manner
split, subdivide or combine the outstanding Class A Common Shares or Class B
Common Shares, the outstanding shares of the other such class of Common Shares
shall be proportionally subdivided or combined in the same manner and on the
same basis as the outstanding shares of the other class of Common Shares have
been split, subdivided or combined.
 
    8.  NO PREEMPTIVE RIGHTS.  No holder of Class A Common Shares or Class B
Common Shares shall, by reason of such holding, have any preemptive right to
subscribe to any additional issue of stock of any class or series of the
Corporation or to any security of the Corporation convertible into such stock.
 
    9.  CONSIDERATION FOR SALE FOR SHARES.  The Board of Directors shall have
the power to issue and sell all or any part of any class of stock herein or
hereafter authorized to such persons, firms, associations or corporations, and
for such consideration as the Board of Directors shall from time to time, in its
discretion, determine, whether or not greater consideration could be received
upon the issue or sale of the same number of shares of another class, and as
otherwise permitted by law.
 
                                       4
<PAGE>
    10.  CONSIDERATION FOR PURCHASE OF SHARES.  The Board of Directors shall
have the power to purchase any class of stock herein or hereafter authorized
from such persons, firms, associations or corporations, and for such
consideration as the Board of Directors shall from time to time, in its
discretion, determine, whether or not less consideration could be paid upon the
purchase of the same number of shares of another class, and as otherwise
permitted by law.
 
    C.  The Preferred Shares may be issued from time to time in one or more
series. The Board of Directors is hereby authorized, by filing a certificate (a
"Preferred Shares Designation") pursuant to the Delaware General Corporation
Law, to fix or alter from time to time the designation, powers, preferences and
rights of the shares of each such series and the qualifications, limitations or
restriction of any wholly unissued series of Preferred Shares, and to establish
from time to time the number of shares constituting any such series or any of
them; and to increase or decrease the number of shares of any series subsequent
to the issuance of shares of that series, but not below the number of shares of
such series then outstanding. The Board of Directors shall designate each series
to distinguish it from other series and classes of stock of the Corporation,
shall specify the number of shares to be included in the series, and shall fix
the terms, rights, restrictions and qualifications of the shares of the series,
including any preferences, voting powers, dividend rights and redemption,
sinking fund and conversion rights. Subject to the express terms of any other
series of Preferred Shares outstanding at the time, the Board of Directors may
increase or decrease the number of shares or alter the designation or classify
or reclassify any unissued shares of a particular series of Preferred Stock by
fixing or altering in any one or more respects from time to time before issuing
the shares, any terms, rights, restrictions and qualifications of the shares. In
case the number of shares of any series shall be decreased in accordance with
the foregoing sentence, the shares constituting such decrease shall resume the
status that they had prior to the adoption of the resolution originally fixing
the number of shares of such series. The Board of Directors shall have the power
to purchase any of the Preferred Shares herein or hereafter authorized from such
persons, firms, or corporations, and for such consideration as the Board of
Directors shall from time to time, in its discretion, determine, whether or not
less consideration could be paid upon the purchase of the same number of shares
of another class, and as otherwise permitted by law.
 
    There shall be a series of Preferred Stock designated "Series A Cumulative
Convertible Preferred Shares" (the "Convertible Preferred Shares") which shall
have the powers, preferences and rights as follows:
 
    1.  RANK.  The Convertible Preferred Shares shall have a par value of $1.00
per share. The Convertible Preferred Shares will rank, with respect to dividend
rights and rights on liquidation, winding-up and dissolution, (i) senior to all
classes of common stock of the Corporation, as they exist on the date hereof or
as such stock may be constituted from time to time, and each other class or
series of capital stock or preferred stock established by the Board of Directors
to the extent the terms of such stock do not expressly provide that it ranks
senior to or on a parity with the Convertible Preferred Shares as to dividend
rights and rights on liquidation, winding-up and dissolution (collectively,
together with the Common Shares, the "Junior Securities"), (ii) on a parity with
each other class or series of capital stock or of preferred stock issued by the
Corporation established by the Board of Directors to the extent the terms of
such stock expressly provide that it will rank on a parity with the Convertible
Preferred Shares as to dividend rights and rights on liquidation, winding-up and
dissolution (collectively, the "Parity Securities"), and (iii) junior to each
other class of capital stock or series of preferred stock established by the
Board to the extent the terms of such stock expressly provide that it will rank
senior to the Convertible Preferred Shares as to dividend rights and rights on
liquidation, winding-up and dissolution (collectively, the "Senior Securities").
Each share of the Convertible Preferred Shares shall rank equally in all respect
with each other share of the Convertible Preferred Shares.
 
    2.  AUTHORIZED NUMBER.  The authorized number of shares constituting the
Convertible Preferred Shares shall be 11,000,000 shares.
 
                                       5
<PAGE>
    3.  DIVIDENDS.  Holders of Convertible Preferred Shares will be entitled to
receive, when, as and if declared by the Board of Directors out of funds of the
Corporation legally available therefor, cash dividends at an annual rate of 4%
of the Stated Value per share of Convertible Preferred Shares, payable quarterly
in arrears on March 15, June 15, September 15, and December 15, of each year,
commencing , 199 [first dividend date following the Mergers], provided that the
dividend payable on         , 199 [first dividend date following the Mergers]
shall be in an amount determined by assuming that the Convertible Preferred
Shares (a) had been outstanding on         , 199 [the date immediately following
the last dividend payment date on the FHP Series A Cumulative Convertible
Preferred Stock] (the "Transition Period Commencement Date"), and (b) had been
entitled to receive, when, as and if declared by the Board of Directors out of
funds of the Corporation legally available therefor, cash dividends at an annual
rate of (i) 5% of an amount equal to twice the Stated Value per share from such
date through         , 199 [the date of the Merger] (the "Effective Date") and
(ii) 4% of the Stated Value per share from         , 199 [the date immediately
following the date of the Merger] through         , 199 [the first dividend date
following the Merger]. Each dividend will be payable to holders of record as
they appear on the books of the Corporation at the close of business on a record
date, not more than 60 nor less than 15 days before the payment date, fixed by
the Board of Directors. Dividends will be cumulative from the date of original
issuance of the Convertible Preferred Shares, which will be the Effective Date,
provided that, for purposes of dividends payable on         , 199 [the first
dividend payment date following the Mergers] in respect of the period from the
Transition Period Commencement Date through the Effective Date (the "Transition
Period"), the Transition Period Commencement Date will be treated as the
issuance date for the Convertible Preferred Shares. Except as otherwise provided
in this subparagraph 3, dividends for each full dividend period will be computed
by dividing the annual dividend rate by four and dividends payable for any
period less than a full dividend period, which may include, without limitation,
dividends payable with respect to the Transition Period, will be computed on the
basis of a 360-day year consisting of twelve 30-day months. The Convertible
Preferred Shares will not be entitled to any dividends, whether payable in cash,
property or stock, in excess of full cumulative dividends. No interest, or sum
of money in lieu of interest, will be payable in respect of any accrued and
unpaid dividends. No full dividends may be declared or paid or funds set apart
for the payment of dividends on any Parity Securities (except dividends on
Parity Securities paid in shares of Junior Securities) for any period unless
full cumulative dividends to be paid hereunder prior to the date thereof shall
have been paid, or contemporaneously are declared and paid, or declared and a
sum sufficient for payment thereof is set apart for such payment on the
Convertible Preferred Shares in accordance with the terms hereof. If full
dividends are not so paid, the Convertible Preferred Shares shall share
dividends PRO RATA with the Parity Securities according to the amount of
dividends due and payable with respect to each. No dividends may be paid or set
apart for such payment, or other distributions made on Junior Securities (except
dividends on Junior Securities paid in additional shares of Junior Securities),
and no Convertible Preferred Shares, Parity Securities or Junior Securities may
be repurchased, redeemed or otherwise retired nor may funds be set apart for
payment with respect thereto, nor shall the Corporation permit any corporation
or entity directly or indirectly controlled by the Corporation to purchase any
Convertible Preferred Shares, Parity Securities or Junior Securities, if full
cumulative dividends to be paid hereunder prior to the date thereof have not
been paid on the Convertible Preferred Shares. Notwithstanding the foregoing,
the Corporation may (i) make redemptions, purchases or other acquisitions of
Convertible Preferred Shares, Parity Securities or Junior Securities payable in
Junior Securities or repurchases of Convertible Preferred Shares, Parity
Securities or Junior Securities in the ordinary course of business pursuant to
the terms of any current or future employee stock incentive plan or similar plan
adopted by the Board and (ii) make redemptions of Rights (as defined in Section
6 below) distributed pursuant to a Rights Agreement (as defined in Section 6
below).
 
    4.  LIQUIDATION RIGHTS.  The Stated Value of each share of Convertible
Preferred Shares shall be $25.00. In the event of any voluntary or involuntary
liquidation, dissolution or winding-up of the Corporation, after satisfaction of
the claims of creditors and any holders of Senior Securities and
 
                                       6
<PAGE>
before any payment or distribution of assets is made on any Junior Securities,
including, without limitation, the Common Shares, (i) the holders of Convertible
Preferred Shares shall receive a liquidation preference equal to the Stated
Value of their shares, and shall be entitled to receive an amount equal to all
accrued and unpaid dividends through the date of distribution (whether or not
declared), and (ii) the holders of any Parity Securities shall be entitled to
receive an amount equal to the full respective liquidation preferences
(including any premium) to which they are entitled and shall receive an amount
equal to all accrued and unpaid dividends with respect to their respective
shares through and including the date of distribution (whether or not declared).
If, upon such a voluntary or involuntary liquidation, dissolution or winding-up
of the Corporation, the assets of the Corporation are insufficient to pay in
full the amounts described above as payable with respect to the Convertible
Preferred Shares and any Parity Securities, the holders of the Convertible
Preferred Shares and such Parity Securities will share ratably in any
distribution of assets of the Corporation, first in proportion to their
respective liquidation preferences until such preferences are paid in full, and
then in proportion to their respective amounts of accrued but unpaid dividends.
After payment of any such liquidation preference and accrued but unpaid
dividends, the Convertible Preferred Shares will not be entitled to any further
participation in any distribution of assets by the Corporation. Neither the sale
or transfer of all or any part of the assets of the Corporation for cash,
securities or other property, nor the merger or consolidation of the Corporation
into or with any other corporation or a merger of any other corporation with or
into the Corporation, will be deemed to be a liquidation, dissolution or
winding-up of the Corporation.
 
    5.  VOTING RIGHTS.
 
    (a) Except as provided below or as may be required by Delaware law or
provided by the resolution creating any other series of Preferred Shares, the
holders of Convertible Preferred Shares will not be entitled to vote. So long as
any shares of Convertible Preferred Shares are outstanding, the vote or consent
of the holders of 66 2/3% of the outstanding shares of Convertible Preferred
Shares, voting together as a single class, shall be necessary to (i) increase or
decrease the par value of the shares of Convertible Preferred Shares or (ii)
alter or change the powers, preferences, or special rights of the shares of
Convertible Preferred Shares so as to affect them adversely or (iii) authorize
or issue any additional class or series of Parity Securities or Senior
Securities, or any security convertible into Parity Securities or Senior
Securities.
 
    (b) (i)  In the event that any accrued dividends (whether or not declared)
on the Convertible Preferred Shares shall not have been paid in an aggregate
amount equal to or greater than six quarterly dividends, the maximum authorized
number of directors of the Corporation will be automatically increased by two,
and holders of Convertible Preferred Shares shall be entitled to vote their
shares of Convertible Preferred Shares, together with the holders of any Parity
Securities upon which like voting rights have been conferred and are exercisable
(the "Voting Parity Securities"), in accordance with the procedures set forth
below, to elect, as a class, an additional two directors. So long as any shares
of Convertible Preferred Shares shall be outstanding, the holders of shares of
Convertible Preferred Shares shall retain the right to vote and elect, with the
holders of such Voting Parity Securities, as a class, two directors until all
accrued but unpaid dividends on the Convertible Preferred Shares are paid in
full or declared and set aside for payment. The period during which holders of
Convertible Preferred Shares retain such right is referred to as a "Default
Period".
 
        (ii) So long as any shares of Convertible Preferred Shares shall be
    outstanding, during any Default Period, the voting right described in
    subsection (i) above may be exercised initially at a special meeting called
    pursuant to subsection (iii) below or at any annual meeting of stockholders.
    The absence of a quorum of holders of Common Shares (or any class thereof)
    shall not affect the exercise of such voting rights by the holders of
    Convertible Preferred Shares and Voting Parity Securities. Holders of
    Convertible Preferred Shares and Voting Parity Securities shall be entitled,
    as among the class of holders of Convertible Preferred Shares and Voting
    Parity Securities, to one vote for each $25.00 of liquidation preference
    represented by the shares so held.
 
                                       7
<PAGE>
       (iii) Unless the holders of Convertible Preferred Shares and Voting
    Parity Securities, if any are then outstanding, have, during an existing
    Default Period, previously exercised their right to elect directors, the
    Board may, and upon the request of the holders of record of not less than
    10% of the aggregate liquidation preference of Convertible Preferred Shares
    and Voting Parity Securities, the Board shall, order the calling of a
    special meeting of holders of Convertible Preferred Shares and Voting Parity
    Securities, if any are then outstanding, which meeting shall thereupon be
    called by the Chairman of the Board, the President, a Vice President or the
    Secretary of the Corporation. Notice of such meeting and of any annual
    meeting at which holders of Convertible Preferred Shares and Voting Parity
    Securities are entitled to vote pursuant to this subsection (iii) shall be
    given to each holder of record of Convertible Preferred Shares by mailing a
    copy of such notice to such holder at such holder's last address as it
    appears on the books of the Corporation. Such meeting shall be called for a
    date not later than 90 days after such order or request, or, in default of
    the calling of such meeting within 90 days after such order or request, such
    meeting may be called on similar notice by any stockholder or stockholders
    owning in the aggregate not less than 10% of the aggregate liquidation
    preference of the Convertible Preferred Shares and Voting Parity Securities.
    Notwithstanding the provisions of this subsection (iii), the Corporation
    shall not be required to call such a special meeting if such request is
    received less then 120 days before the date fixed for the next ensuing
    annual meeting of stockholders of the Corporation, at which meeting such
    newly created directorships shall be filled by vote of the holders of
    Convertible Preferred Shares and Voting Parity Securities.
 
       (iv) During any Default Period, the holders of Class A Common Shares, and
    other classes of stock of the Corporation, if applicable, shall continue to
    be entitled to elect all of the Directors unless and until the holders of
    Convertible Preferred Shares and Voting Parity Securities shall have
    exercised their right to elect two Directors voting as a class. After the
    exercise of this right (x) the Directors so elected by the holders of
    Convertible Preferred Shares and Voting Parity Securities shall continue in
    office until the earlier of (A) such time as their successors shall have
    been elected by such holders and (B) the expiration of the Default Period,
    and (y) any vacancy in the Board of Directors with respect to a Directorship
    to be elected pursuant to this subparagraph (b) by the holders of
    Convertible Preferred Shares and Voting Parity Securities may be filled by
    vote of the remaining Director previously elected by such holders.
    References in this subsection (b) to Directors elected by the holders of a
    particular class of stock shall include Directors elected by such Directors
    to fill vacancies as provided in clause (y) of the foregoing sentence.
 
        (v) Immediately upon the expiration of a Default Period, (x) the right
    of the holders of Convertible Preferred Shares to elect Directors pursuant
    to this subparagraph (b) shall cease, subject to continuing application of
    subparagraph (b)(i) upon each and every subsequent reoccurrence of the event
    described therein, (y) the term of any Directors elected by the holders of
    Convertible Preferred Shares and Voting Parity Securities pursuant to this
    subparagraph (b) shall terminate, and (z) the number of Directors shall be
    such number as may be provided for in the Certificate of Incorporation or
    bylaws irrespective of any increase made pursuant to subsection (i) of this
    subparagraph (b) (such number being subject, however, to subsequent change
    in any manner provided by law or in the Certificate of Incorporation or
    bylaws).
 
    6.  CONVERSION.
 
    (a) RIGHT TO CONVERT. Each share of Convertible Preferred Shares will be
convertible (the rights to convert described in this subsection (a) are referred
to as the "Conversion Rights") at the option of the holder thereof, into such
number of fully paid and non-assessable shares of Class B Common Shares
(together with any Rights (as defined in subsection (b)(iii) below) associated
therewith) as is equal to (A) the sum of (i) twice the Stated Value of the
Convertible Preferred Shares plus (ii) accrued but unpaid dividends in arrears
thereon to which the holder converting such shares is entitled, divided
 
                                       8
<PAGE>
by (B) the Conversion Price then in effect. The initial "Conversion Price" for
the Convertible Preferred Shares shall be $[        (1)] and shall be subject to
adjustment as described below. The holders of Convertible Preferred Shares at
the close of business on a dividend payment record date shall be entitled to
receive the dividend payable on such shares on the corresponding dividend
payment date notwithstanding the conversion of such Convertible Preferred Shares
or the Corporation's default on payment of the dividend due on such dividend
payment date. However, shares of Convertible Preferred Shares surrendered for
conversion during the period from the close of business on any record date for
the payment of dividends on such shares to the opening of business on the
corresponding dividend payment date (except shares called for redemption to
occur during the period from the record date to the close of business on the
payment date pursuant to Section 7 below) must be accompanied by payment of an
amount equal to the dividend payable on such shares on such dividend payment
date. A holder of Convertible Preferred Shares on a dividend payment record date
who (or whose transferee) tenders shares of Convertible Preferred Shares on a
dividend payment date will be entitled to receive the dividend payable on such
shares by the Corporation on such date, and such converting holder need not
include payment in the amount of such dividend upon surrender of shares of
Convertible Preferred Shares for conversion. Except as provided above, no
payment or adjustment will be made on account of accrued or unpaid dividends
upon the conversion of shares of Convertible Preferred Shares. Shares of
Convertible Preferred Shares called for redemption will not be convertible after
the close of business on the day preceding the date fixed for redemption, unless
the Corporation defaults in payment of the redemption price.
 
    (b)  ANTI-DILUTION PROVISIONS.  The Conversion Price is subject to
adjustment after the issuance of the Convertible Preferred Shares from time to
time as follows:
 
        (i) In case the Corporation shall (1) pay a dividend or make a
    distribution on Common Shares in shares of Common Shares, (2) subdivide its
    outstanding shares of Common Shares into a greater number of shares or (3)
    combine its outstanding shares of any class of Common Shares into a smaller
    number of shares, the Conversion Price in effect immediately prior to such
    action shall be adjusted (and any other appropriate action taken by the
    Corporation) so that the holder of any Convertible Preferred Shares
    thereafter surrendered for conversion shall be entitled to receive the
    number of shares of Common Shares which such holder would have been entitled
    to receive immediately following such action had the holder's Convertible
    Preferred Shares been converted immediately prior thereto. An adjustment
    made pursuant to this subsection (i) shall become effective immediately
    (except as provided in subsection (vi) below) after the record date in the
    case of a dividend or distribution and shall become effective immediately
    after the effective date in the case of a subdivision or combination.
 
        (ii) In case the Corporation shall issue rights, options or warrants to
    all holders of its outstanding shares of Common Shares, or of its
    outstanding shares of any class or series of Common Shares, entitling them,
    for a period expiring within 45 days after the record date mentioned below,
    to subscribe for or purchase shares of Common Shares at a price per share
    less than the Current Market Price per share (as defined in subsection (v)
    below) of such offered Common Shares on the record date mentioned below,
    then the Conversion Price in effect immediately prior thereto shall be
    adjusted so that it shall equal the price determined by multiplying the
    Conversion Price in effect immediately prior to the date of issuance of such
    rights, options or warrants by a fraction of which
 
           (1) the numerator shall be the sum of (A) the number of shares of
       Common Shares outstanding on the date of issuance of such rights, options
       or warrants immediately prior to such issuance plus (B) the number of
       shares of such offered Common Shares which the aggregate offering price
       of the total number of shares so offered would purchase at such
 
- ------------------------
(1) A price equal to the FHP existing conversion price of $31 per share times a
    fraction, the numerator of which is $1.00 and the denominator of which is
    the Final Exchange Ratio as defined in the Reorganization Agreement.
 
                                       9
<PAGE>
       Current Market Price (determined by multiplying such total number of
       shares offered for subscription or purchase by the sum of the exercise
       price of such rights, options or warrants plus the value of any
       consideration per share paid to the Corporation for such rights, options
       or warrants and dividing the product so obtained by such Current Market
       Price), and
 
           (2) the denominator shall be the sum of (A) the number of shares of
       Common Shares outstanding on the date of issuance of such rights, options
       or warrants immediately prior to such issuance plus (B) the number of
       additional shares of Common Shares which are so offered for subscription
       or purchase.
 
        Such adjustment shall be made successively whenever any rights, options
    or warrants are issued, and shall become effective immediately (except as
    provided in subsection (vi) below) after the record date for the
    determination of stockholders entitled to receive such rights, options or
    warrants; provided, however, in the event that all the shares of Common
    Shares offered for subscription or purchase are not delivered upon the
    exercise of such rights, options or warrants, upon the expiration of such
    rights, options or warrants the Conversion Price shall be readjusted to the
    Conversion Price which would have been in effect had the numerator and the
    denominator of the foregoing fraction and the resulting adjustment been made
    based upon the number of shares of Common Shares actually delivered upon the
    exercise of such rights, options or warrants rather than upon the number of
    shares of Common Shares offered for subscription or purchase. In determining
    the value of any consideration received by the Corporation for such rights,
    options or warrants, the determination of the Board of Directors in good
    faith shall be conclusive and shall be described in a Board resolution.
 
       (iii) Notwithstanding subsection (ii) above, any adjustments to the
    Conversion Price to account for the issuance of rights ("Rights") under a
    shareholder rights plan or agreement, "poison pill" or similar arrangement
    (a "Rights Agreement") adopted subsequent to the date hereof shall be made
    when such Rights become exercisable or exchangeable by the holder thereof
    for Common Shares (Common Shares issued pursuant to the exercise of, or
    exchange by the Corporation for, such Rights are referred to as "Rights
    Stock") pursuant to a Rights Agreement at a price per share less than the
    Current Market Price per share of such Common Shares on the date of such
    exercise or exchange. The Conversion Price in effect immediately prior to
    such exercise or exchange shall be adjusted so that it shall equal the price
    determined by multiplying the Conversion Price in effect immediately prior
    to the date of such exercise or exchange by a fraction of which
 
           (1) the numerator shall be the sum of (A) the number of shares of
       Common Shares of the type issued pursuant to the exercise of, or exchange
       by the Corporation for, such Rights outstanding on the date of issuance
       of such Rights Stock immediately prior to such issuance plus (B) the
       number of shares of Common Shares of the type issued pursuant to the
       exercise of, or exchange by the Corporation for, such Rights which the
       aggregate consideration received for the total number of shares of Rights
       Stock so issued would purchase at such Current Market Price (determined
       by multiplying such total number of shares of Rights Stock by the
       consideration received per share of such Rights Stock and dividing the
       product so obtained by such Current Market Price), and
 
           (2) the denominator shall be the sum of (A) the number of shares of
       Common Shares of the type issued pursuant to the exercise of, or exchange
       by the Corporation for, such Rights outstanding on the date of issuance
       of such Rights Stock immediately prior to such issuance plus (B) the
       number of additional shares of Rights Stock which are so issued.
 
        Such adjustment shall be made successively whenever any Rights Stock is
    issued, and shall become effective immediately (except as provided in
    subsection (vi) below) after the issuance of Rights Stock. If after the
    applicable "Distribution Date" or a similar date (as defined in a Rights
    Agreement) holders converting shares of Convertible Preferred Shares are,
    for any reason, not entitled to receive the Rights or similar rights,
    options or warrants which would otherwise be attributable (but for the date
    of conversion) to the shares of Common Shares received upon such
 
                                       10
<PAGE>
    conversion), then a reducing adjustment shall be made in the Conversion
    Price to reflect the fair market value of the Rights or similar rights,
    options or warrants. If such an adjustment is made and the Rights or similar
    rights, options or warrants are later exchanged, redeemed, invalidated or
    terminated, then a corresponding reversing adjustment shall be made to the
    Conversion Price, on an equitable basis, to take account of such event.
    However, the Corporation may elect to provide that such shares of Common
    Shares issuable upon conversion of the Convertible Preferred Shares, whether
    or not issued after the Distribution Date or such similar date for such
    Rights, will be accompanied by the Rights which would otherwise be
    attributable (but for the date of conversion to such shares of Common
    Shares, in which event the preceding two sentences shall not apply).
 
       (iv) In case the Corporation shall distribute to substantially all
    holders of Common Shares, or to substantially all holders of its outstanding
    shares of any class or series of Common Shares, evidences of indebtedness,
    equity securities (including equity interests in the Corporation's
    subsidiaries) other than Common Shares or other assets (other than cash
    dividends paid out of earned surplus of the Corporation or, if there shall
    be no earned surplus, out of net profits for the fiscal year in which the
    dividend is made and/or the preceding fiscal year), or shall distribute to
    substantially all holders of Common Shares or to substantially all holders
    of any class or series of Common Shares, rights, options or warrants to
    subscribe to securities (other than any rights, options or warrants referred
    to in subsection (ii) above or Rights referred to in subparagraph (iii)
    above), then in each such case the Conversion Price shall be adjusted so
    that it shall equal the price determined by multiplying the Conversion Price
    in effect immediately prior to the date of such distribution by a fraction
    of which the numerator shall be the Current Market Price per share of the
    Common Shares (as determined below) on the record date mentioned below less
    the quotient of the then fair market value of the assets, evidences of
    indebtedness and equity securities so distributed, or of such subscription
    rights, warrants or options, divided by the number of shares of Common
    Shares outstanding on such record date, and of which the denominator shall
    be such Current Market Price of the Common Shares. For the purposes of this
    subsection (iv), in the event of a distribution of shares of capital stock
    or other securities of any subsidiary of the Corporation as a dividend on
    shares of Common Shares, the "then fair market value" of the shares or other
    securities so distributed shall be the value of such shares or other
    securities on the record date mentioned below as determined by the Board of
    Directors, whose good faith determination shall be conclusive evidence of
    such value, and shall be described in a Board resolution. Such adjustment
    shall become effective immediately (except as provided in subsection (vi)
    below) after the record date for the determination of stockholders entitled
    to receive such distribution.
 
        (v) For the purpose of any computation under subsection (ii), (iii) or
    (iv) above, the "Current Market Price" per share of stock on any date shall
    be (A) deemed to be the average of the last sale prices of a share of such
    shares for the fifteen consecutive trading days commencing 20 trading days
    before the earliest of the date in question and the date before the "ex
    date" with respect to the issuance or distribution requiring such
    computation, or (B) in each case where the Current Market Price per share is
    to be determined with respect to the two classes or series of Common Shares
    considered together, deemed to equal the quotient of (i) the sum of (a) AvgA
    multiplied by Na and (b) AvgB multiplied by Nb, divided by (ii) Nt, where
 
<TABLE>
<S>        <C>        <C>
AvgA       =          the average of the last sale prices of a share of Class A Common
                      Shares for the fifteen consecutive trading days commencing 20
                      trading days before the earliest of the date in question and the
                      date before the "ex date" with respect to the issuance or
                      distribution requiring such computation,
 
AvgB       =          the average of the last sale prices of a share of Class B Common
                      Shares for the fifteen consecutive trading days commencing 20
                      trading days before the earliest of the date in question and the
                      date before the "ex date" with respect to the issuance or

Na         =          the average number of shares of Class A Common Shares outstanding
                      during the fifteen consecutive trading days commencing 20 trading
                      days before the earliest of the date in question and the date before
                      the "ex date" with respect to the issuance or distribution requiring
                      such computation,
 
Nb         =          the average number of shares of Class B Common Shares outstanding
                      during the fifteen consecutive trading days commencing 20 trading
                      days before the earliest of the date in question and the date before
                      the "ex date" with respect to the issuance or distribution requiring
                      such computation, and
 
Nt         =          the sum of Na and Nb.
</TABLE>
 
    For purposes of this subsection (v), the term "ex date," when used with
    respect to any issuance or distribution, means the first date on which the
    stock trades regular way on the principal national securities exchange on
    which the stock is listed or admitted to trading (or if not so listed or
    admitted, on Nasdaq, or a similar organization if Nasdaq is no longer
    reporting trading information) without the right to receive such issuance or
    distribution.
 
       (vi) In any case in which this Section shall require that an adjustment
    be made immediately following a record date or immediately following the
    exercise of, or exchange of a right, option or warrant, the Corporation may
    elect to defer the effectiveness of such adjustment (but in no event until a
    date later then the later of the "ex date" as defined above and the
    effective date of the event giving rise to such adjustment), in which case
    the Corporation shall, with respect to any Convertible Preferred Shares
    converted after the date of such exercise or exchange or such record date,
    as the case may be, and before such adjustment shall have become effective
    (1) defer making any cash payment or issuing to the holder of such
    Convertible Preferred Shares the number of shares of Common Shares and other
    capital stock of the Corporation issuable upon such conversion in excess of
    the number of shares of Common Shares and other capital stock of the
    Corporation issuable thereupon only on the basis of the Conversion Price
    prior to adjustment, and (2) not later than five business days after such
    adjustment shall have become effective, pay to such holder the appropriate
    cash payment and issue to such holder the additional shares of Common Shares
    and other capital stock of the Corporation issuable on such conversion.
 
       (vii) No adjustment in the Conversion Price shall be required if the
    holders of Convertible Preferred Shares are to participate in the
    transaction on a basis and with notice that the Board of Directors
    determines in good faith to be fair and appropriate in light of the basis
    and notice on which holders of Common Shares participate in the transaction.
    In addition, no adjustment in the Conversion Price shall be required unless
    such adjustment (plus any adjustments not previously made by reason of this
    subsection (vii)) would require an increase or decrease of at least 1% in
    the Conversion Price; provided, that any adjustments which by reason of this
    subsection (vii) are not required to be made shall be carried forward and
    taken into account in any subsequent adjustment. All calculations under this
    Section shall be made to the nearest cent or to the nearest one-hundredth of
    a share, as the case may be.
 
      (viii) Whenever the Conversion Price is adjusted as provided above:
 
           (1) the Corporation shall compute the adjusted Conversion Price and
       shall promptly file with the stock transfer or conversion agent, as
       appropriate, for the Convertible Preferred Shares, a certificate signed
       by a principal financial officer of the Corporation setting forth the
       adjusted Conversion Price and showing in reasonable detail the facts upon
       which such adjustment is based and the computation thereof; and
 
           (2) a notice stating that the Conversion Price has been adjusted and
       setting forth the adjusted Conversion Price shall, as soon as
       practicable, be sent by first-class mail to the holders of record of the
       Convertible Preferred Shares.
 
                                       12
<PAGE>
           In case:
 
               (A) the Corporation shall take any action which would require an
           adjustment to the Conversion Price pursuant to subsection (iv) above;
 
               (B) the Corporation shall authorize the granting to the holders
           of its Common Shares of rights, options or warrants entitling them to
           subscribe for or purchase any shares of capital stock of any class or
           of any other rights;
 
               (C) of any reorganization or reclassification of the Common
           Shares or any class or series of Common Shares (other than a
           subdivision or combination of its outstanding Common Shares), or of
           any consolidation or merger to which the Corporation is a party and
           for which approval of any stockholders of the Corporation is
           required, or of the sale, lease or transfer of all or substantially
           all the assets of the Corporation; or
 
               (D) of the voluntary or involuntary liquidation, dissolution or
           winding-up of the Corporation;
 
       then the Corporation shall cause to be mailed to the stock transfer or
       conversion agent, as appropriate, for the Convertible Preferred Shares
       and to the holders of record of Convertible Preferred Shares, at least 20
       days (for 10 days in any case described in subsections (A) or (B) above)
       prior to the applicable record date or effective date specified below, a
       notice stating (x) the date as of which the holders of record of Common
       Shares to be entitled in such dividend, distribution, rights, options or
       warrants are to be determined, or (y) the date on which such
       reorganization, reclassification, consolidation, merger, sale, lease,
       transfer, liquidation, dissolution or winding-up is expected to become
       effective, and the date or dates as of which it is expected that holders
       of record of Common Shares shall be entitled to exchange their shares for
       securities or other property, if any, deliverable upon such
       reorganization, reclassification, consolidation, merger, sale, lease,
       transfer, liquidation, dissolution or winding-up. Neither the failure to
       give the notice required by this subsection (viii), nor any defect
       therein, to any particular holder shall affect the sufficiency of the
       notice or the legality or validity of any such dividend, distribution,
       right, option, warrant, reorganization, reclassification, consolidation,
       merger, sale, lease, transfer, liquidation, dissolution or winding-up, or
       the vote authorizing any such action with respect to the other holders.
 
       (ix) To the extent permitted by law, the Corporation from time to time
    may reduce the Conversion Price by any amount for any period of at least 20
    days (or such other period as may then be required by applicable law) if the
    Board of Directors has made a determination in good faith that such
    reduction would be in the best interests of the Corporation, which
    determination shall be conclusive. No reduction in the Conversion Price
    pursuant to this subsection (ix) shall become effective unless the
    Corporation shall have mailed a notice, at least 15 days prior to the date
    on which such reduction is scheduled to become effective, to each holder of
    Convertible Preferred Shares. Such notice shall be given by first-class
    mail, postage prepaid, at such holder's address as it appears on the books
    of the Corporation. Such notice shall state the amount per share by which
    the Conversion Price will be reduced and the period for which such reduction
    will be in effect.
 
        (x) At its option, the Corporation may make such reduction in the
    Conversion Price, in addition to those otherwise required by this Section 6,
    as the Board deems advisable to avoid or diminish any income tax to holders
    of Common Shares resulting from any dividend or distribution of stock (or
    rights to acquire stock) or from any event treated as such for income tax
    purposes; provided that any such reduction shall not be effective until
    written evidence of the action of the Board of Directors authorizing such
    reduction shall be filed with the Secretary of the Corporation and notice
    thereof shall have been given by first-class mail, postage prepaid, to each
    holder of Convertible Preferred Shares at such holder's address as it
    appears on the books of the Corporation.

    (c)  CONSOLIDATION, MERGER OR SALE OF ASSETS.  If any transaction shall
occur, including without limitation (i) any recapitalization or reclassification
of shares of Common Shares or any class or series of Common Shares (other than a
change in par value, or from par value to no par value, or from no par value to
par value, or as a result of a subdivision or combination of the Common Shares),
(ii) any consolidation or merger of the Corporation with or into another person
or any merger of another person into the Corporation (other than a merger in
which the Corporation is the surviving corporation and that does not result in a
reclassification, conversion, exchange or cancellation of Common Shares, or any
class or series of Common Shares), (iii) any sale, lease or transfer of all or
substantially all of the assets of the Corporation, (iv) any compulsory share
exchange, or (v) any conversion of all of the outstanding Class B Common Shares
into Class A Common Shares, pursuant to any of which holders of Class B Common
Shares shall be entitled to receive other securities, cash or other property,
then appropriate provision shall be made so that the holder of each share of
Convertible Preferred Shares then outstanding shall have the right thereafter to
receive on account of such share only the kind and amount of the securities,
cash or other property that would have been receivable upon such
recapitalization, reclassification, consolidation, merger, sale, lease,
transfer, share exchange or conversion by a holder of the number of shares of
Class B Common Shares issuable upon conversion of such share of Convertible
Preferred Shares immediately prior to such recapitalization, reclassification,
consolidation, merger, sale, lease, transfer or share exchange, and the
Corporation shall not enter into any such merger, consolidation, sale, lease,
transfer or share exchange unless the company formed by such consolidation or
resulting from such merger or that acquires such assets or that acquires the
Corporation's shares, as the case may be, shall make provisions in its
certificate or articles of incorporation or other constituent document or
certificate of merger or other document effecting any such merger,
consolidation, sale, lease, transfer or share exchange to establish such right.
Upon the occurrence of any transaction described in the preceding sentence
(except clause (i) thereof), the Convertible Preferred Shares then outstanding
shall be deemed converted, subject nevertheless to the provisions of Section 8
to the extent applicable.
 
    (d)  ACCRUED DIVIDENDS AND FRACTIONAL SHARES.  Dividends shall cease to
accrue on shares of the Convertible Preferred Shares surrendered for conversion
into Class B Common Shares pursuant to this Section or Section 8 below. No
fractional shares of Class B Common Shares shall be issued upon conversion of
the Convertible Preferred Shares, and any portion of Convertible Preferred
Shares surrendered for conversion which would otherwise result in a fractional
share of Class B Common Shares shall be redeemed for cash in an amount equal to
the product of such fraction multiplied by the closing price of the Class B
Common Shares on the last business day prior to conversion.
 
    (e)  MECHANICS OF CONVERSION.  Before any holder of Convertible Preferred
Shares shall be entitled to convert such stock into shares of Class B Common
Shares and to receive certificates therefor, such holder shall surrender the
certificate or certificates for the Convertible Preferred Shares to be
converted, duly endorsed, at the office of the Corporation or of any transfer
agent for the Convertible Preferred Shares, and shall give written notice to the
Corporation at such office that such holder elects to convert the same. The
Corporation shall, within 10 days after such delivery, issue and deliver at such
office to such holder of the Convertible Preferred Shares (or to any other
person specified in the notice delivered by such holder) a certificate or
certificates for the number of shares of Class B Common Shares to which such
holder shall be entitled as aforesaid and a check payable to the holder for any
cash amounts payable as the result of a conversion into fractional shares of
Class B Common Shares. Such conversion shall be deemed to have been made
immediately prior to the close of business on the date of such surrender of the
shares of Convertible Preferred Shares to be converted, and the Person or
persons entitled to receive the shares of Class B Common Shares issuable upon
such conversion shall be treated for all purposes as the record holder or
holders of such shares of Class B Common Shares on such date. In case any
certificate for shares of the Convertible Preferred Shares shall be surrendered
for conversion of only a part of the shares represented thereby, the Corporation
shall deliver within 10 days at such office to or upon the written order of the
holder thereof, a certificate or certificates for the number of shares of
Convertible Preferred Shares represented by such surrendered certificate which
are not being converted. Notwithstanding the foregoing, the
 
                                       14
<PAGE>
Corporation shall not be obligated to issue certificates evidencing the shares
of Class B Common Shares issuable upon such conversion unless the certificates
evidencing the Convertible Preferred Shares are either delivered to the
Corporation or its transfer agent or the Corporation or its transfer agent shall
have received evidence satisfactory to it evidencing that such certificates have
been lost, stolen or destroyed and the holder of such Convertible Preferred
Shares executes an agreement satisfactory to the Corporation to indemnify the
Corporation from any loss incurred by it in connection with such certificates.
The issuance of certificates of shares of Class B Common Shares issuable upon
conversion of shares of Convertible Preferred Shares shall be made without
charge to the converting holder for any tax imposed in respect of the issuance
thereof; provided that the Corporation shall not be required to pay any tax
which may be payable with respect to any transfer involved in the issue and
delivery of any certificate in a name other than that of the holder of the
shares of Convertible Preferred Shares being converted.
 
    (f)  ADOPTION OF RIGHTS AGREEMENT.  The Corporation shall not adopt a Rights
Agreement unless such Rights Agreement shall provide that (i) each holder of a
share of Convertible Preferred Shares shall be entitled to receive thereunder,
upon conversion of such share of Convertible Preferred Shares (in accordance
with the terms hereof), prior to the earlier to occur of the date of redemption
of Rights issued under such Rights Agreement, the date of expiration of the
Rights issued under such Rights Agreement, or the date the Conversion Price of
the Convertible Preferred Shares is adjusted pursuant to subsection 6(b)(iii)
above rights for each share of Common Shares issued upon conversion of such
share of Convertible Preferred Shares in an amount equal to the amount of Rights
issued with respect to each outstanding share of Common Shares issued rights
pursuant to such Rights Agreement and (ii) if such Rights are redeemed prior to
the conversion of any share of Convertible Preferred Shares into Common Shares,
then, upon conversion of such share of Convertible Preferred Shares, the holder
thereof shall receive an amount in cash equal to the amount in cash that such
holder would have received had he converted such share of Convertible Preferred
Shares prior to such redemption.
 
    7.  OPTIONAL REDEMPTION.  On or after June 17, 1998, the Corporation may, at
its option, redeem all or from time to time any part of the shares of
Convertible Preferred Shares, out of funds legally available therefor, upon
giving a notice of redemption as set forth below, at the following redemption
prices per share (expressed as percentages of the Stated Value thereof), plus an
amount equal to accrued and unpaid dividends, if any (whether or not declared),
up to but excluding the date fixed for redemption, if redeemed during the
twelve-month period commencing on June 17, 1998 of the years indicated below:

2004...................................................................       100.0%
</TABLE>
 
    If fewer than all of the outstanding shares of the Convertible Preferred
Shares are to be redeemed, the number of shares to be redeemed shall be
determined by the Board of Directors in good faith and the shares to be redeemed
will be determined pro rata as nearly as practicable, or by such other method as
the Board of Directors may determine to be fair and appropriate. Convertible
Preferred Shares may not be redeemed unless full cumulative dividends have been
paid on the Convertible Preferred Shares for all past dividend periods.
 
    Notice of redemption of Convertible Preferred Shares will be given by (i)
first-class mail, not less than 30 nor more than 60 days prior to the date fixed
for redemption thereof, to each record holder of shares of Convertible Preferred
Shares to be redeemed at the address of such holder in the books of the
Corporation and (ii) publication in THE WALL STREET JOURNAL. On the date such
notices are
 
                                       15
<PAGE>
mailed, the Corporation shall issue a press release announcing the redemption.
The mailed and published notice shall state, as appropriate: (1) the redemption
date and record date for purposes of such redemption; (2) the number of shares
of Convertible Preferred Shares to be redeemed and, if fewer than all
outstanding shares of Convertible Preferred Shares held by any holder are to be
redeemed, the number of shares to be redeemed from such holder; (3) the place or
places at which certificates for such shares are to be surrendered; (4) the then
current redemption price; and (5) that dividends on the Convertible Preferred
Shares to be redeemed shall cease to accrue on such Redemption Date, except as
otherwise provided herein. If such notice of redemption has been given, from and
after the specified redemption date (unless the Corporation defaults in making
payment of the redemption price), dividends on the Convertible Preferred Shares
so called for redemption will cease to accrue, such shares will no longer be
deemed to be outstanding, and all rights of the holders thereof as stockholders
of the Corporation (except the right to receive the redemption price and any
dividends due on a dividend payment date after the redemption date relating to a
dividend record date prior to such redemption date) will cease.
 
    8.  CHANGE IN CONTROL.  If there occurs a Change in Control (as defined
below) with respect to the Corporation, then each share of Convertible Preferred
Shares may be converted (the rights to convert described in this Section
referred to as the "Special Conversion Rights"), at the option of the holder
thereof at any time from the date of such Change in Control until the expiration
of 60 days after the date of the Conversion Notice (as defined below) by the
Corporation to all holders of the Convertible Preferred Shares, into, at its
option, either (A) such number of fully paid and non-assessable shares of Class
B Common Shares as is equal to the Stated Value of the Convertible Preferred
Shares divided by the Special Conversion Price (as defined below) or (B) an
amount in cash equal to the Stated Value of the Convertible Preferred Shares
plus an amount equal to any accrued but unpaid dividends thereon. The "Special
Conversion Price" shall be the closing price of the Class B Common Shares on the
last trading day prior to the date the Corporation gives the Conversion Notice
(as defined below) to the holders of Convertible Preferred Shares.
 
    Within five days after the occurrence of a Change in Control, the
Corporation shall give notice of the occurrence of the Change in Control and of
the Special Conversion Rights set forth herein in accordance with the procedures
set forth below to each holder of Convertible Preferred Shares (the "Conversion
Notice").
 
    Each Conversion Notice shall state:
 
    (a) that a Change in Control has occurred (and shall specify the date of
occurrence), and that the holder's Special Conversion Rights may be exercised in
accordance with this Section;
 
    (b) the expiration date of the Special Conversion Rights;
 
    (c) that a holder of Convertible Preferred Shares, in order to exercise
Special Conversion Rights, must deliver on or before the fifth day prior to the
expiration date of the Special Conversion Rights written notice to the
Corporation of the holder's exercise of those rights, together with the
certificate evidencing such holder's shares with respect to which the rights are
being exercised, duly endorsed for transfer;
 
    (d) the Special Conversion Price and the Conversion Price which would
otherwise be applicable;
 
    (e) a description of the procedure which a holder must follow to exercise
its Special Conversion Rights; and
 
    (f) that holders of Convertible Preferred Shares electing to have such
shares converted will be required to surrender the certificates evidencing such
shares for delivery of shares of Class B Common Shares.
 
    The Conversion Notice shall be given by first-class mail, postage paid, to
the holders of record of Convertible Preferred Shares at their respective
addresses as they appear on the books of the Corporation.
 
                                       16
<PAGE>
    No failure of the Corporation to give the Conversion Notice shall limit any
holder's right to exercise its Special Conversion Rights.
 
    Exercise of the Special Conversion Rights by a holder of Convertible
Preferred Shares will be irrevocable. The Corporation shall not enter into any
consolidation, merger or sale of assets, unless in connection therewith the
holders of Convertible Preferred Shares exercising Special Conversion Rights
will be entitled to receive the same consideration as received for the number of
shares of Class B Common Shares into which their shares of Convertible Preferred
Shares would have been converted pursuant to the Special Conversion Rights. The
Special Conversion Rights are in addition to the regular Conversion Rights that
apply to the Convertible Preferred Shares.
 
    The Corporation may, at its option, elect to pay holders of Convertible
Preferred Shares exercising Special Conversion Rights an amount in cash equal to
the Stated Value of the Convertible Preferred Shares plus an amount equal to any
accrued but unpaid dividends thereon.
 
    "Change in Control" means any of the following: (i) the sale, lease,
conveyance or other disposition of all or substantially all of the Corporation's
assets as an entirety or substantially as an entirety to any person or "group"
(within the meaning of Section 13(d)(3) of the 1934 Act) in one or a series of
transactions, provided that a transaction where the holders of Common Shares
immediately prior to such transaction own, directly or indirectly, 50% or more
of the common stock of such person or group immediately after such transactions
shall not be a Change in Control; (ii) the acquisition by the Corporation and/or
any of its subsidiaries of 50% or more of the aggregate voting power of the
Common Shares in one transaction or a series of related transactions; (iii) the
liquidation or dissolution of the Corporation, provided that a liquidation or
dissolution of the Corporation which is part of a transaction or series of
related transactions that does not constitute a Change in Control under the
"provided" clause of clause (i) above shall not constitute a Change in Control
under this clause (iii); or (iv) any transaction or series of transactions (as a
result of a tender offer, merger, consolidation or otherwise) that results in,
or that is in connection with, (a) any person, including a "group" (within the
meaning of Section 13(d)(3) of the 1934 Act) that includes such person,
acquiring "beneficial ownership" (as defined in Rule 13d-3 under the 1934 Act),
directly or indirectly, of 50% or more of the aggregate voting power of the
Common Shares of the Corporation or any person that possesses "beneficial
ownership" (as defined in Rule 13d-3 under the 1934 Act), directly, of 50% or
more of the aggregate voting Power of the Common Shares, or (b) less than 50%
(measured by the aggregate voting power of all classes) of the Corporation's
Common Shares being registered under Section 12(b) or 12(g) of the 1934 Act.
 
    9.  STATUS OF REACQUIRED SHARES.  If shares of Convertible Preferred Shares
are converted pursuant to Section 6 hereof or redeemed pursuant to Section 7
hereof, the shares so converted or redeemed shall, upon compliance with any
statutory requirements, assume the status of authorized but unissued shares of
preferred stock of the Corporation, but may not be reissued as Convertible
Preferred Shares.
 
    10.  RESERVED SHARES.  So long as any shares of Convertible Preferred Shares
remain outstanding, the Corporation agrees to keep reserved for issuance in
connection with the conversion of the Convertible Preferred Shares at all times
a number of authorized but unissued shares of Class B Common Shares at least
equal to 150% of the number of shares of Class B Common Shares issuable upon
conversion at the Conversion Price of all of the Convertible Preferred Shares
outstanding at such time. The Corporation shall take all action necessary so
that Class B Common Shares so issued will be validly issued, fully paid and
non-assessable. The Corporation shall use its best efforts to list the Class B
Common Shares required to be delivered upon conversion of the shares of
Convertible Preferred Shares, prior to such conversion, upon each national
securities exchange, if any, upon which the outstanding Common Shares are listed
at the time of such delivery.
 
    11.  PREEMPTIVE RIGHTS.  The Convertible Preferred Shares are not entitled
to any preemptive or subscription rights in respect of any securities of the
Corporation.

    12.  NOTICES.  Except as otherwise provided herein, all notices, requests,
demands, and other communications hereunder shall be in writing and shall be
deemed to have been duly given if delivered by and when sent by telex or
telecopier (with receipt confirmed), provided a copy is also sent by express
(overnight, if possible) courier, addressed (i) in the case of a holder of
Convertible Preferred Shares, to such holder's address as it appears on the
books of the Corporation, and (ii) in the case of the Corporation, to the
Corporation's principal executive offices to the attention of the Corporation's
President,
 
    13.  SEVERABILITY OF PROVISIONS.  Whenever possible, each provision of this
paragraph C shall be interpreted in a manner as to be effective and valid under
applicable law, but if any provision hereof is held to be prohibited by or
invalid under applicable law, such provision shall be ineffective only to the
extent of such prohibition or invalidity, without invalidating or otherwise
adversely affecting the remaining provisions hereof. If a court of competent
jurisdiction should determine that a provision hereof would be valid or
enforceable if a period of time were extended or shortened or a particular
percentage were increased or decreased, then such court may make such change as
shall be necessary to render the provision in question effective and valid under
applicable law.
 
                                       V
 
    The number of Directors of the Corporation shall be ten. The number of
Directors may hereafter be fixed from time to time by bylaw or amendment duly
adopted by the Board of Directors, provided, however, that the number of
Directors shall not be more than twelve nor less than five, except as otherwise
may be required to implement the provisions of paragraph C.5(b) of Article IV
hereof.
 
                                       VI
 
    A.  The Board of Directors shall be and is divided in to three classes,
Class I, Class II and Class III. The number of Directors in each class shall be
the whole number contained in the quotient arrived at by dividing the authorized
number of Directors by three, and if a fraction is also contained in such
quotient then if such fraction is one-third (1/3) the extra Director shall be a
member of Class I and if the fraction is two-thirds (2/3) one of the extra
Directors shall be a member of Class I and the other shall be a member of Class
II. Each Director shall serve for a term ending on the date of the third annual
meeting following the annual meeting at which such Director was elected,
provided, however, that the Directors initially appointed to Class I shall serve
for a term ending on the date of the third annual meeting next following the
date hereof, the Directors initially appointed to Class II shall serve for a
term ending on the date of the second annual meeting next following the date
hereof, and the Directors initially appointed to Class III shall serve for a
term ending on the date of the first annual meeting next following the date
hereof.
 
    B.  In the event of any increase or decrease in the authorized number of
Directors, (1) each Director then serving as such shall nevertheless continue as
a Director of the class of which he is a member until the expiration of his
current term, or his prior death, resignation or removal, and (2) the newly
created or eliminated Directorships resulting from such increase shall be
apportioned by the Board of Directors to such class or classes as shall, so far
as possible, bring the number of Directors in the respective classes into
conformity with the formula in this Article, as applied to the new authorized
number of Directors.
 
    C.  Notwithstanding any of the foregoing provisions of this Article, each
Director shall serve until his successor is elected and qualified or until his
death, resignation or removal. A Director shall not be removed from office prior
to the expiration of his term except by the affirmative vote or written consent
of not less than sixty-six and two-thirds percent (66 2/3%) of the total votes
entitled to be cast in an election of Directors. Should a vacancy occur or be
created, the remaining Directors (even though less than a quorum) may fill the
vacancy for the full term of the class in which the vacancy occurs or is
created.

                                      VII
 
    A.  In addition to requirements of any applicable statute, the affirmative
vote or written consent of not less than 66 2/3% of the total votes entitled to
be cast in an election of Directors, considered for purposes of this Article as
one class, shall be required for approval or authorization of any Business
Transaction (as hereinafter defined) between the Corporation and any Control
Person (as hereinafter defined); provided, however, that such additional voting
requirement shall not be applicable if:
 
        (1) The Business Transaction was approved by a two-thirds vote of the
    Board of Directors of the Corporation prior to the acquisition by the
    Control Person, together with its Affiliates and Associates (as hereinafter
    defined), of stock of the Corporation, which, in the aggregate, bears the
    rights to 10% or more of the total votes entitled to be cast in an election
    of Directors; or
 
        (2) The Business Transaction was approved by a two-thirds vote of the
    Board of Directors of the Corporation after the acquisition by the Control
    Person, together with its Affiliates and Associates, of stock of the
    Corporation, which, in the aggregate, bears the rights to 10% or more of the
    total votes entitled to be cast in an election of Directors, and such
    acquisition by such Control Person and its Affiliates and Associates was
    unanimously approved by the Board of Directors of the Corporation; or
 
        (3) The Business Transaction is solely between the Corporation and
    another corporation, 50% or more of the voting stock of which is owned by
    the Corporation and none of which is owned by a Control Person, and each
    holder of stock of the Corporation receives the same type of consideration
    in proportion to his holdings; or
 
        (4) Both of the following are satisfied:
 
           (a) the cash or fair market value of the property, securities or
       other consideration to be received per share in the Business Transaction
       by holders of the stock of the Corporation is not less than the higher of
       (i) the highest price per share (including brokerage commissions,
       soliciting dealers' fees, dealer-management compensation, and other
       expenses, including, but not limited to, newspaper advertisements,
       printing and attorney's fees) paid by such Control Person in acquiring
       any of its holdings of the Corporation's stock, or (ii) the highest per
       share market price of the stock of the Corporation during the 3-month
       period immediately preceding the date of the proxy statement described in
       (c) below; and
 
           (b) a proxy statement responsive to the requirements of the 1934 Act
       shall be mailed to public stockholders of the Corporation for the purpose
       of soliciting stockholder approval of such Business Transaction and shall
       contain at the front thereof, in a prominent place, any recommendations
       as to the advisability (or inadvisability) of the Business Transaction
       which the Continuing Directors, or any of them, may choose to state, and,
       if deemed advisable by a majority of the Continuing Directors, an opinion
       of a reputable investment banking firm as to the fairness (or unfairness)
       of the terms of such Business Transaction, from the point of view of the
       remaining public stockholders of the Corporation (such investment banking
       firm to be selected by a majority of the Continuing Directors and to be
       paid a reasonable fee for their services by the Corporation upon receipt
       of such opinion).
 
    B.  For the purposes of this Article:
 
        (1) The term "Control Person" shall mean and include any individual,
    corporation, partnership or other person or entity which, together with its
    Affiliates and Associates, "beneficially owns" (as this term is defined on
    the date on which this Article becomes effective in Rule 13d-3 of the
    General Rules and Regulations under the 1934 Act) in the aggregate, stock of
    the Corporation, which bears the rights to 10% or more of the total votes
    entitled to be cast in an election of Directors, and any Affiliate or
    Associate (as those terms are defined on the date of which this Article is
    adopted in Rule 12b-2 of the General Rules and Regulations under the 1934
    Act) of any such individual, corporation, partnership or other person or
    entity;
 
                                       19
<PAGE>
        (2) The term "Business Transaction" shall mean (a) any merger or
    consolidation of the Corporation with or into a Control Person, (b) any
    sale, lease, exchange, transfer or other disposition, including without
    limitation a mortgage or any other security device, of all or any
    Substantial Part (as hereinafter defined) of the assets of the Corporation
    (including, without limitation, any voting securities of a subsidiary) or of
    a subsidiary, to a Control Person, (c) any merger of consolidation of a
    Control Person with or into the Corporation or a subsidiary of the
    Corporation, (d) any sale, lease, exchange, transfer or other disposition of
    all or any Substantial Part (as hereinafter defined) of the assets of a
    Control Person to the Corporation or a subsidiary of the Corporation, (e)
    the issuance of any securities of the Corporation or a subsidiary of the
    Corporation to a Control Person, (f) the acquisition by the Corporation or a
    subsidiary of the Corporation of any securities of a Control Person, (g) any
    reclassification or recapitalization (including any reverse stock split)
    involving stock of the Corporation, consummated within five (5) years after
    a Control Person becomes a Control Person, (h) any plan or proposal by a
    Control Person for the dissolution or liquidation of the Corporation, and
    (i) any agreement, contract or other arrangement providing for any of the
    transactions described in this definition of Business Transaction;
 
        (3) The term "Continuing Director" shall mean any Director who was
    elected by the public stockholders of the Corporation prior to the
    acquisition by the Control Person, together with its Affiliates and
    Associates, in the aggregate, of stock of the Corporation, which bears the
    rights to 10% or more of the total votes entitled to be cast in an election
    of Directors, or a person recommended by succeed a Continuing Director by a

    A.  N-T Holdings, Inc. ("Corporation") is authorized to issue three classes
of shares of stock to be designated, respectively, "Class A Common Shares,"
"Class B Common Shares," and "Preferred Shares." The total number of shares of
stock which the Corporation shall have authority to issue is two hundred forty
million (240,000,000). The total number of Class A Common Shares which the

each such Class B Common Share shall be one cent ($0.01). The total number of

    B.  The powers, preferences and rights of the holders of Class A Common
Shares and Class B Common Shares (collectively, the "Common Shares"), and the
qualifications, limitations or restrictions thereof, shall be in all respects
identical, except as otherwise required by law or expressly provided in this
Certificate of Incorporation, as amended, and subject to the powers, preferences
and rights of the holders of Preferred Shares, as provided in or as otherwise
determined by the Board of Directors pursuant to paragraph C of this Article IV.
 
    1.  DIVIDENDS.  Dividends may be declared and paid to the holders of the
Class A Common Shares and the Class B Common Shares in cash, property, or other
securities of the Corporation out of any funds legally available therefore. If
and when dividends on the Class A Common Shares and the Class B Common Shares
are declared payable from time to time by the Board of Directors, whether
payable in cash, in property or in securities of the Corporation, the holders of
the Class A Common Shares and the holders of the Class B Common Shares shall be
entitled to share equally, on a per share basis, in such dividends, except that,
dividends or other distributions payable on the Common Shares in Common Shares
shall be made to all holders of Common Shares and may be made (i) in Class B
Common Shares to the record holders of Class A Common Shares and to the record
holders of Class B Common Shares, (ii) in Class A Common Shares to the record
holders of Class A Common Shares and in Class B Common Shares to the record

                                       1
<PAGE>
    2.  DISTRIBUTION ON DISSOLUTION, ETC.  Upon any liquidation, dissolution or
winding up of the Corporation, whether voluntary or involuntary, the remaining
net assets of the Corporation shall, after payment in full of the liquidation
preference, if any, of any outstanding Preferred Shares, be distributed pro rata
to the holders of the Class A Common Shares and the Class B Common Shares in
accordance with their respective rights and interests.
 
    3.  VOTING RIGHTS.
 
    (a) At each annual or special meeting of the shareholders, each holder of
Class A Common Shares shall be entitled to one (1) vote in person or by proxy
for each Class A Common Share standing in his name on the stock transfer records
of the corporation in connection with the election of directors and all other
actions submitted to a vote of shareholders; holders of Class B Common Shares
shall not vote on any matters except as otherwise provided by this Certificate
of Incorporation, as amended, and the Delaware General Corporation Law.
 
    (b) The holders of Class B Common Shares shall be entitled to vote
separately as a group only with respect to (i) proposals to change the par value
of the Class B Common Shares, (ii) amendments to this Certificate of
Incorporation that alter or change the powers, preference or special rights of
the holders of Class B Common Shares so as to affect them adversely, and (iii)
such other matters as may require separate group voting under this Certificate
of Incorporation, as amended, and the Delaware General Corporation Law.
 
    (c) The number of authorized Class B Common Shares may be increased or
decreased (but not below the number of shares then outstanding) by the
affirmative vote of the holders of a majority of the Class A Common Shares.
 
    4.  CONVERSION.
 
    (a) All outstanding Class B Common Shares may be converted into Class A
Common Shares on a share-for-share basis by the Board of Directors if, as a
result of the existence of the Class B Common Shares, either the Class A Common
Shares or Class B Common Shares is or both are excluded from trading on the New
York Stock Exchange, the American Stock Exchange and all other principal
national securities exchanges then in use and also is excluded from quotation on
the National Association of Securities Dealers Automated Quotation ("Nasdaq")
National Market and other comparable national quotation systems then in use. In
making such determination, the Board of Directors may conclusively rely on any
information or documentation available to it, including filings made with the
Securities and Exchange Commission, any stock exchange, the National Association
of Securities Dealers, Inc. or any other governmental or regulatory agency or
any written instrument purporting to be authentic.
 
    (b) All outstanding Class B Common Shares shall be converted into Class A
Common Shares on a share-for-share basis if at any time the number of
outstanding Class A Common Shares, as reflected on the stock transfer records of
the Corporation, falls below ten percent (10%) of the aggregate number of
outstanding Class A Common Shares and of Class B Common Shares. For purposes of
the immediately preceding sentence, any Common Shares repurchased and held as
treasury shares or canceled by the Corporation shall no longer be deemed
"outstanding" from and after the date of repurchase.
 
    (c) In the event of any conversion of the Class B Common Shares pursuant to
subparagraph 4(a) or 4(b), certificates which formerly represented outstanding
shares of Class B Common Shares will thereafter be deemed to represent a like
number of shares of Class A Common shares and all authorized Common Shares shall
consist of only Class A Common Shares.
 
    5.  CLASS B COMMON SHARE PROTECTION PROVISION.
 
    (a) If, after the effective time (the "Effective Time") of the PacifiCare
Merger (the "PacifiCare Merger"), as that term is defined in the Amended and
Restated Agreement and Plan of Reorganization dated as of September 17, 1996,
among PacifiCare Health Systems, Inc., N-T Holdings, Inc., Neptune Merger Corp.,
Tree Acquisition Corp. and FHP International Corporation, as amended (the
 
                                       2
<PAGE>
"Reorganization Agreement"), any person or group acting in concert acquires
beneficial ownership of shares representing 10% or more of the then issued and
outstanding Class A Common Shares (excluding the number of shares beneficially
owned by such person or group at or before the Effective Time and other than
upon the issuance or sale by the Corporation, by operation of law, including a
merger, consolidation or reorganization of a beneficial owner, by will or the
laws of descent and distribution, by gift or by foreclosure of a bona fide
loan), and such person or group (a "Significant Shareholder") does not own an
equal or greater percentage of the Class B Common Shares acquired after the
Effective Time, such Significant Shareholder must, within a ninety (90) day
period beginning the day after becoming a Significant Shareholder, make a public
cash tender offer in compliance with all applicable laws and regulations to
acquire additional Class B Common Shares as provided in this subparagraph B (5)
of Article IV (a "Class B Protection Transaction").
 
    (b) In each Class B Protection Transaction, the Significant Shareholder must
make a public tender offer to acquire that number of Class B Common Shares
determined by (i) multiplying the percentage of outstanding Class A Common
Shares beneficially owned by such Significant Shareholder and acquired after the
Effective Time by such Significant Shareholder by the total number of shares of
Class B Common Shares outstanding on the date such person or group became a
Significant Shareholder, and (ii) subtracting therefrom the total number of
shares of Class B Common Shares beneficially owned on such date and acquired
after the Effective Time by such Significant Shareholder (including shares
acquired on such date at or prior to the time such person or group became a
Significant Shareholder). The Significant Shareholder must acquire all of such
shares validly tendered; provided, however, that if the number of Class B Common
Shares tendered to the Significant Shareholder exceeds the number of shares
required to be acquired pursuant to the formula set forth in this subparagraph
5(b), the number of Class B Common Shares acquired from each tendering holder
shall be pro rata in proportion to the total number of Class B Common Shares
tendered by all tendering holders.
 
    (c) The offer price for any Class B Common Shares required to be purchased
by the Significant Shareholder pursuant to this subparagraph B(5) shall be the
greater of (i) the highest price per share paid by the Significant Shareholder
for any Class A Common Share in the six month period ending on the date such
person or group became a Significant Shareholder or (ii) the highest bid price
of a Class A Common Share or Class B Common Share on the Nasdaq National Market
(or such other exchange or quotation system as is then the principal trading
market for such shares) on the date such person or group became a Significant
Shareholder or (iii) the highest bid price of a Class A Common Share or Class B
Common Share on the Nasdaq National Market (or such other exchange or quotation
system as is then the principal trading market for such shares) on the date
preceding the date the Significant Shareholder makes the tender offer required
by this subparagraph B(5). For purposes of subparagraph B(5)(d) below, the
applicable date for the calculations required by clauses (i) and (ii) of the
preceding sentence shall be the date on which the Significant Shareholder
becomes required to engage in a Class B Protection Transaction. In the event
that the Significant Shareholder has acquired Class A Common Shares in the six
month period ending on the date such person or group becomes a Significant
Shareholder for consideration other than cash, the value of such consideration
per Class A Common Share shall be as determined in good faith by the Board of
Directors.
 
    (d) A Class B Protection Transaction shall also be required to be effected
by any Significant Shareholder each time that the Significant Shareholder
acquires beneficial ownership of the next higher integral multiple of 5% (e.g.,
15%, 20%, 25%, etc.) of the outstanding Class A Common Shares after the
Effective Time (other than upon the issuance or sale by the Corporation, by
operation of law, including a merger, consolidation or reorganization of a
beneficial owner, by will or the laws of descent and distribution, by gift, or
by foreclosure of a bona fide loan) if such Significant Shareholder does not
then own an equal or greater percentage of the Class B Common Shares acquired
after the Effective Time. Such Significant Shareholder shall be required to make
a public tender offer to acquire that
 
                                       3
<PAGE>
number of Class B Common Shares prescribed by the formula set forth in
subparagraph B(5)(b) above, and must acquire all shares validly tendered or a
pro rata portion thereof, as specified in subparagraph B(5)(b), at the price
determined pursuant to subparagraph B (5)(c) above.
 
    (e) If any Significant Shareholder fails to make an offer required by this
subparagraph B(5) of Article IV, or to purchase shares validly tendered and not
withdrawn (after proration, if any), such Significant Shareholder shall not be
entitled to vote any Class A Common Shares beneficially owned by such
Significant Shareholder unless and until such requirements are complied with or
unless and until all Class A Common Shares causing such offer requirement to be
effective are no longer beneficially owned by such Significant Shareholder.
 
    (f) The Class B Protection Transaction requirement shall not apply to any
increase in percentage ownership of Class A Common Shares resulting solely from
a change in the total amount of Class A Common Shares outstanding, provided that
any acquisition after such change which resulted in any person or group owning
10% or more of the Class A Common Shares (excluding in the case of the numerator
but not the denominator of the calculation of such percentage, Class A Common
Shares held by such Significant Shareholder immediately after the Effective
Time) shall be subject to any Class B Protection Transaction requirement that
would be imposed with respect to a Significant Shareholder pursuant to this
subparagraph B(5) of Article IV.
 
    (g) All calculations with respect to percentage ownership of issued and
outstanding shares of either class of Common Shares will be based upon the
numbers of issued and outstanding shares reported by the Corporation on the last
to be filed of (i) the Corporation's most recent annual report on Form 10-K,
(ii) its most recent Quarterly Report on Form 10-Q, or (iii) its most recent
Current Report on Form 8-K.
 
    (h) For purposes of this subparagraph B(5) of this Article IV, the term
"person" means a natural person, corporation, partnership, trust, association,
government, or political subdivision, agency or instrumentality of a government,
or other entity. "Beneficial ownership" shall be determined pursuant to Rule
13d-3 promulgated under the Securities Exchange Act of 1934, as amended (the
"1934 Act"), or any successor regulation. The formation or existence of a
"group" shall be determined pursuant to Rule 13d-5(b) under the 1934 Act or any
successor regulation.
 
    6.  MERGER OR CONSOLIDATION.  In the event of a merger or consolidation of
the Corporation with or into another entity (whether or not the Corporation is
the surviving entity), the holders of Class B Common Shares shall be entitled to
receive the same per share consideration as the per share consideration, if any,
received by any holder of the Class A Common Shares in such merger or
consolidation; provided, however, that this restriction shall not apply to the
PacifiCare Merger.
 
    7.  SPLITS, SUBDIVISIONS, ETC.  If the Corporation shall in any manner
split, subdivide or combine the outstanding Class A Common Shares or Class B
Common Shares, the outstanding shares of the other such class of Common Shares
shall be proportionally subdivided or combined in the same manner and on the
same basis as the outstanding shares of the other class of Common Shares have
been split, subdivided or combined.
 
    8.  NO PREEMPTIVE RIGHTS.  No holder of Class A Common Shares or Class B
Common Shares shall, by reason of such holding, have any preemptive right to
subscribe to any additional issue of stock of any class or series of the
Corporation or to any security of the Corporation convertible into such stock.
 
    9.  CONSIDERATION FOR SALE FOR SHARES.  The Board of Directors shall have
the power to issue and sell all or any part of any class of stock herein or
hereafter authorized to such persons, firms, associations or corporations, and
for such consideration as the Board of Directors shall from time to time, in its
discretion, determine, whether or not greater consideration could be received
upon the issue or sale of the same number of shares of another class, and as
otherwise permitted by law.
 
                                       4
<PAGE>
    10.  CONSIDERATION FOR PURCHASE OF SHARES.  The Board of Directors shall
have the power to purchase any class of stock herein or hereafter authorized
from such persons, firms, associations or corporations, and for such
consideration as the Board of Directors shall from time to time, in its
discretion, determine, whether or not less consideration could be paid upon the
purchase of the same number of shares of another class, and as otherwise
permitted by law.
 
    C.  The Preferred Shares may be issued from time to time in one or more
series. The Board of Directors is hereby authorized, by filing a certificate (a
"Preferred Shares Designation") pursuant to the Delaware General Corporation
Law, to fix or alter from time to time the designation, powers, preferences and
rights of the shares of each such series and the qualifications, limitations or
restriction of any wholly unissued series of Preferred Shares, and to establish
from time to time the number of shares constituting any such series or any of
them; and to increase or decrease the number of shares of any series subsequent
to the issuance of shares of that series, but not below the number of shares of
such series then outstanding. The Board of Directors shall designate each series
to distinguish it from other series and classes of stock of the Corporation,
shall specify the number of shares to be included in the series, and shall fix
the terms, rights, restrictions and qualifications of the shares of the series,
including any preferences, voting powers, dividend rights and redemption,
sinking fund and conversion rights. Subject to the express terms of any other
series of Preferred Shares outstanding at the time, the Board of Directors may
increase or decrease the number of shares or alter the designation or classify
or reclassify any unissued shares of a particular series of Preferred Stock by
fixing or altering in any one or more respects from time to time before issuing
the shares, any terms, rights, restrictions and qualifications of the shares. In
case the number of shares of any series shall be decreased in accordance with
the foregoing sentence, the shares constituting such decrease shall resume the
status that they had prior to the adoption of the resolution originally fixing
the number of shares of such series. The Board of Directors shall have the power
to purchase any of the Preferred Shares herein or hereafter authorized from such
persons, firms, or corporations, and for such consideration as the Board of
Directors shall from time to time, in its discretion, determine, whether or not
less consideration could be paid upon the purchase of the same number of shares
of another class, and as otherwise permitted by law.
 
    There shall be a series of Preferred Stock designated "Series A Cumulative
Convertible Preferred Shares" (the "Convertible Preferred Shares") which shall
have the powers, preferences and rights set forth on Exhibit A hereto.
 
                                       V
 
    The number of Directors of the Corporation shall be ten. The number of
Directors may hereafter be fixed from time to time by bylaw or amendment duly
adopted by the Board of Directors, provided, however, that the number of
Directors shall not be more than twelve nor less than five, except as otherwise
may be required to implement the provisions of paragraph C.5(b) of Article IV
hereof.
 
                                       VI
 
    A.  The Board of Directors shall be and is divided in to three classes,
Class I, Class II and Class III. The number of Directors in each class shall be
the whole number contained in the quotient arrived at by dividing the authorized
number of Directors by three, and if a fraction is also contained in such
quotient then if such fraction is one-third (1/3) the extra Director shall be a
member of Class I and if the fraction is two-thirds (2/3) one of the extra
Directors shall be a member of Class I and the other shall be a member of Class
II. Each Director shall serve for a term ending on the date of the third annual
meeting following the annual meeting at which such Director was elected,
provided, however, that the Directors initially appointed to Class I shall serve
for a term ending on the date of the third annual meeting next following the
date hereof, the Directors initially appointed to Class II shall serve for a
term ending on the date of the second annual meeting next following the date
hereof, and the Directors initially appointed to Class III shall serve for a
term ending on the date of the first annual meeting next following the date
hereof.
 
                                       5
<PAGE>
    B.  In the event of any increase or decrease in the authorized number of
Directors, (1) each Director then serving as such shall nevertheless continue as
a Director of the class of which he is a member until the expiration of his
current term, or his prior death, resignation or removal, and (2) the newly
created or eliminated Directorships resulting from such increase shall be
apportioned by the Board of Directors to such class or classes as shall, so far
as possible, bring the number of Directors in the respective classes into
conformity with the formula in this Article, as applied to the new authorized
number of Directors.
 
    C.  Notwithstanding any of the foregoing provisions of this Article, each
Director shall serve until his successor is elected and qualified or until his
death, resignation or removal. A Director shall not be removed from office prior
to the expiration of his term except by the affirmative vote or written consent
of not less than sixty-six and two-thirds percent (66 2/3%) of the total votes
entitled to be cast in an election of Directors. Should a vacancy occur or be
created, the remaining Directors (even though less than a quorum) may fill the
vacancy for the full term of the class in which the vacancy occurs or is
created.
 
                                      VII
 
    A.  In addition to requirements of any applicable statute, the affirmative
vote or written consent of not less than 66 2/3% of the total votes entitled to
be cast in an election of Directors, considered for purposes of this Article as
one class, shall be required for approval or authorization of any Business
Transaction (as hereinafter defined) between the Corporation and any Control
Person (as hereinafter defined); provided, however, that such additional voting
requirement shall not be applicable if:
 
        (1) The Business Transaction was approved by a two-thirds vote of the
    Board of Directors of the Corporation prior to the acquisition by the
    Control Person, together with its Affiliates and Associates (as hereinafter
    defined), of stock of the Corporation, which, in the aggregate, bears the
    rights to 10% or more of the total votes entitled to be cast in an election
    of Directors; or
 
        (2) The Business Transaction was approved by a two-thirds vote of the
    Board of Directors of the Corporation after the acquisition by the Control
    Person, together with its Affiliates and Associates, of stock of the
    Corporation, which, in the aggregate, bears the rights to 10% or more of the
    total votes entitled to be cast in an election of Directors, and such
    acquisition by such Control Person and its Affiliates and Associates was
    unanimously approved by the Board of Directors of the Corporation; or
 
        (3) The Business Transaction is solely between the Corporation and
    another corporation, 50% or more of the voting stock of which is owned by
    the Corporation and none of which is owned by a Control Person, and each
    holder of stock of the Corporation receives the same type of consideration
    in proportion to his holdings; or
 
        (4) Both of the following are satisfied:
 
           (a) the cash or fair market value of the property, securities or
       other consideration to be received per share in the Business Transaction
       by holders of the stock of the Corporation is not less than the higher of
       (i) the highest price per share (including brokerage commissions,
       soliciting dealers' fees, dealer-management compensation, and other
       expenses, including, but not limited to, newspaper advertisements,
       printing and attorney's fees) paid by such Control Person in acquiring
       any of its holdings of the Corporation's stock, or (ii) the highest per
       share market price of the stock of the Corporation during the 3-month
       period immediately preceding the date of the proxy statement described in
       (c) below; and
 
           (b) a proxy statement responsive to the requirements of the 1934 Act
       shall be mailed to public stockholders of the Corporation for the purpose
       of soliciting stockholder approval of such Business Transaction and shall
       contain at the front thereof, in a prominent place, any recommendations
       as to the advisability (or inadvisability) of the Business Transaction
       which the Continuing Directors, or any of them, may choose to state, and,
       if deemed advisable by a
 
                                       6
<PAGE>
       majority of the Continuing Directors, an opinion of a reputable
       investment banking firm as to the fairness (or unfairness) of the terms
       of such Business Transaction, from the point of view of the remaining
       public stockholders of the Corporation (such investment banking firm to
       be selected by a majority of the Continuing Directors and to be paid a
       reasonable fee for their services by the Corporation upon receipt of such
       opinion).
 
    B.  For the purposes of this Article:
 
        (1) The term "Control Person" shall mean and include any individual,
    corporation, partnership or other person or entity which, together with its
    Affiliates and Associates, "beneficially owns" (as this term is defined on
    the date on which this Article becomes effective in Rule 13d-3 of the

FOR IMMEDIATE RELEASE


                            PACIFICARE HEALTH SYSTEMS
                    RECEIVES 1997 MEDICARE RATE INCREASES


     CYPRESS, Calif., September 9, 1996 -- PacifiCare Health Systems, Inc. 
(NASDAQ: PHSYA and PHSYB) announced today that it has received notice from 
the Health Care Financing Administration that its Secure Horizons Medicare 
risk programs will receive an overall weighted average premium rate increase 
of approximately 6.1 percent for the year beginning January 1, 1997. This new 
rate increase compares to the approximately 5.6 percent overall increase 
received for the 1996 year.

     The 1997 average rate increase varies by state and other demographic 
factors. Accordingly, the company will receive increases of approximately 6.3 
percent in California, 6.2 percent in Oklahoma, 1.8 percent in Oregon, 7.5 
percent in Texas and 4.4 percent in Washington.

     "We are pleased with next year's premium rate increases which will allow 
us to continue to provide quality, cost-effective health care products and 
services to the nearly 550,000 seniors who have selected Secure Horizons for 
their health benefits needs," said Alan Hoops, president and chief executive 
officer.

     "Secure Horizons is the largest and, for four years, has been one of the 
fastest-growing Medicare risk programs in the country," Hoops continued. "We 
attribute this success to having highly satisfied members that have access to 
comprehensive health care benefits delivered by a broad selection of very 
capable health care providers.

     "With less than ten percent of the nation's 33 million seniors currently 
in Medicare risk programs, we are excited about the tremendous opportunity 
to introduce our Secure Horizons programs to

many more Medicare eligible persons," said Hoops. "Our recently announced 
plan to acquire FHP International Corporation (NASDAQ: FHPC) will, if 
consummated, give us access to nine new states, many of which have Medicare 
risk penetration rates below the national average."

     Medicare risk programs like PacifiCare's Secure Horizons typically 
provide more benefits and services to seniors than traditional Medicare, with 
the simplicity of no paperwork. Secure Horizons programs offer its members a 
full array of health care benefits including unlimited hospitalization, 
annual physical examinations and other preventive care services for little 
or no premium. Other benefits frequently offered include vision and hearing 
examinations, dental care and prescription drug coverage.

     PacifiCare Health Systems is one of the nation's leading managed health 
care services companies. Primary operations include managed care products for 
employer groups, and Medicare and Medicaid beneficiaries in California, 
Florida, Oklahoma, Oregon, Texas and Washington serving approximately two 
million members. Other specialty managed care operations include Medicare 
risk management services, pharmacy benefit management, military health care 
management, coordination of managed care products for multi-region employers, 
health and life insurance, behavioral health, dental and vision services and 
health promotion.
