(1) PCFL DISPOSITION - Pro forma adjustments to remove the historical operating
    results of PCFL and the assets acquired and liabilities assumed by Total
    Health Choice, Inc.  During the fiscal year ended September 30, 1996, 
    PacifiCare recognized a charge for the impairment of goodwill, the 
    disposition of Pasteur Delivery Systems and restructuring charges associated
    with its Florida operations totaling $68.0 million ($42.4 million or 
    $1.34 per share, net of tax).

    No pro forma adjustments have been made to reflect interest income for the
    fiscal year ended September 30, 1996, or the three months ended December 31,
    1996, on the net proceeds from the Disposition.

(2) CORPORATE ALLOCATIONS - Pro forma adjustment to reflect an increase in
    marketing, general and administrative expenses for corporate allocations
    included in the PCFL results of operations that are expected to remain
    after the Disposition, and to recognize the related tax benefit at the
    statutory tax rate of 40.2%.

(3) INCOME TAXES - Pro forma adjustment to reflect the tax effects of the
    Disposition and related non-deductible goodwill amortization at the
    statutory rates in effect during the fiscal year ended September 30, 1996
    and the three months ended December 31, 1996 (in thousands).

(4) SALES PRICE - Pro forma adjustments to record cash received by PacifiCare
    for the sale of PCFL. The sale of PCFL was effected by the Stock Purchase
    Agreement, as Amended (the "Agreement"), dated February 21, 1997, by and
    between PacifiCare and Total Health Choice, Inc.  The Agreement includes a
    put option whereby in the event that regulatory approvals are not obtained
    by January 31, 1998, Total Health Choice, Inc. shall have the option to
    require PacifiCare to repurchase PCFL for $5.9 million.  PacifiCare,
    therefore, will defer the gain of approximately $1.9 million on the sale of
    PCFL until such regulatory approvals are obtained.

                        POST-CLOSING COVENANTS AND OBLIGATIONS


    10.1 PAYMENT OF THE COMPANY'S LIABILITIES. After the Closing, Buyer shall,
or shall cause the Company to, administer and manage the payment or performance
of all Company Payables in a timely manner, consistent with customary and
prudent business practices. Prior to or as of Closing, Seller shall have
deposited in a special account of the Company the amount of Three Million
Dollars ($3,000,000.00) (the "Special Fund") to be applied to payment of claims
for specialist referrals made by PrimeCare of Florida, Inc. dba PrimeCare
Physician Network, Inc. on or before the Closing Date or claims for hospital
services furnished to PrimeCare patients on or before the Closing Date (the
"PrimeCare Pre-Closing IBNR"). However, Seller's creation of the Special Fund is
conditioned upon the Company assigning to Seller all of the Company s right,
title and interest in and to the PrimeCare Pre-Closing IBNR up to Three Million
Dollars ($3,000,000.00) under that certain Health Services Agreement, dated as
of May 31, 1996, made and entered into by and between the Company and PrimeCare
of Florida.

         Buyer shall, or shall cause the Company to, apply the Special Funds
only to payment of the PrimeCare Pre-Closing IBNR until the Prime Care Pre-
Closing IBNR has been paid in full.  Any of the Special Funds which remain after
the payment of the PrimeCare Pre-Closing IBNR shall be remitted to PrimeCare. 
Creation of the Special Fund creates no liability of Seller for any PrimeCare
Pre-Closing IBNR in excess of the Special Funds.  Except


                                         -30-

<PAGE>

for the Special Fund and those Company Liabilities expressly assumed by Seller
pursuant to the Indemnification Agreement and Section 2.4 above, Buyer, jointly
and severally with the Company, shall be responsible for the payment,
performance and satisfaction of all other Company Liabilities.

    10.2 FURTHER ASSIGNMENTS. If at any time after the Closing legal counsel
for Buyer or Seller shall deem it necessary, advisable or appropriate to take
further or additional steps for the purpose of assigning, transferring,
conveying, perfecting and/or confirming or reducing to possession the Shares or
the Assets, the other party shall execute, acknowledge and deliver any such
assignments, conveyances, certificates or other documents or instruments of
transfer consistent with the terms of this Agreement as may reasonably be
requested by legal counsel.
    
    10.3 OBLIGATIONS RELATING TO THE COMPANY'S EMPLOYEES.
    
         10.3.1 TERMINATING EMPLOYEES. The Company shall have terminated all of
the Company Employees as of the Closing Date.
         
         10.3.2 OBLIGATIONS TO EMPLOY THE COMPANY EMPLOYEES. Buyer agrees to,
or to cause an affiliated management company to use reasonable efforts in good
faith to employ and retain, subject to the limitations in Section 10.3.3, no
less than forty (40) of the terminated Company Employees (the "Minimum Hires").
Buyer agrees to use reasonable efforts in good faith to retain the Minimum Hires
for a period of not less than one hundred (100) days after the Closing Date, and
shall not consummate or cause any "plant closing" or "mass layoff" with respect
to such employees or their business enterprise prior to the expiration of such
100-day period. Any "plant closing" or "mass layoff" instituted by Buyer or its
related or affiliated management company after the Closing shall comply in all
respects with the WARN Act. Nothing in this Section 10.3.2 or in any other
provision of this Agreement shall create any rights which inure to the Company
Employees.

         10.3.3 CONTINUED BENEFITS FOR THE EMPLOYED COMPANY EMPLOYEES. For a
period of not less than six (6) months after the Closing Date, Buyer shall, or
shall cause an affiliated management company to, continue to make available to
any employed Company Employees those employee benefit plans, arrangements and
programs which are provided to similarly situated employees of Buyer or an
affiliated management company which employs such employees. In determining the
extent to which the employed Company Employees may participate in the employee
benefit plans, arrangements or programs of the new employer, Buyer shall credit
such employees' prior service with the Company and/or any of the Company's
affiliates for such purposes as eligibility to participate in, vesting and
calculation of benefits and, if applicable, shall waive any pre-existing
condition limitations or waiting periods for benefits.


                                         -31-

<PAGE>

    10.4 CHANGE NAME OF THE COMPANY. Immediately after the Closing, Buyer shall
cause the Company to change its corporate name to one which does not include the
word "PacifiCare" or any other word or phrase which is confusingly similar to
"PacifiCare." Immediately after the Closing, Buyer shall cause the Company to
immediately discontinue any use of the name or mark "PacifiCare" or "Secure
Horizons" in connection with any of the Company's operations, communications or
marketing, except as reasonably necessary for the collection or enforcement of
pre-Closing obligations or otherwise to identify itself as the legal successor
of the Company.
    
    10.5 RETENTION OF CERTAIN RECORDS BY THE COMPANY. Buyer shall cause the
Company to retain possession of and to not destroy any books, records or other
written materials or information respecting the conduct of the Company's
business prior to the Closing Date for a period of at least seven (7) years from
the date of creation of the book, record or other written material.
    
    10.6 ESTABLISHING THE FINAL BALANCE SHEET. (a) In accordance with the
process and procedures described in this Section 10.6, Buyer and Seller shall
work with the Company to review, verify and, if necessary, adjust the line items
on the Preliminary Balance Sheet for the purpose of establishing the Final
Balance Sheet. The review period shall begin immediately after the Closing and
shall expire thirty (30) days thereafter. During the 30-day review period, Buyer
and Seller shall take reasonable and appropriate steps to verify the following
line items (with their corresponding schedules) of the Preliminary Balance
Sheet: Premiums Receivable, Restricted Investments, Deposits, Other Accrued
Liabilities, Accounts Payable, Unearned Premiums and L/T Debt, Current Portion.
To accomplish such verification, Buyer shall afford Seller access to the books
and records of the Company and its subsidiaries. In the event of a discrepancy
between the amount of any such line item as reflected on the Preliminary Balance
Sheet and the amount of such item, as verified and mutually agreed to by Buyer
and Seller, the appropriate adjustment in such line item shall be made for the
Final Balance Sheet.
    
         (b)  Buyer and Seller also shall review and evaluate the Company's
actual payment experience with respect to the Incurred But Not Paid claims,
exclusive of the PrimeCare IBNR, as reflected on the Preliminary Balance Sheet
(the "Normalized IBNR"). In view of the Company's actual claims payment
experience prior to Closing, Buyer and Seller shall agree to appropriate
adjustments to the Normalized IBNR to be reflected on the Final Balance Sheet.
For the purpose of adjusting the Normalized IBNR, any adjustments shall be
mutually agreed to by Buyer and Seller prior to the Final Adjustment Date. If
Buyer and Seller have not reached mutual agreement as to any such adjustments
prior to the ten (10) business day period preceding such date, then the matter
immediately shall be submitted to the Actuary for its review and determination.
The Actuary's review shall be limited to a determination of the adequacy of the
reserves set aside to pay the then-unpaid Normalized


                                        -32-

<PAGE>

IBNR. In its review and determination, the Actuary shall make a final point
estimate without conservatism of the appropriate reserve amount for the then-
unpaid Normalized IBNR. The Actuary's estimation shall be made and delivered to
Buyer and Seller no later than two (2) business days prior to the Final
Adjustment Date. The Actuary's final point estimate, made without conservatism,
shall be final, binding and conclusive upon Buyer and Seller and shall finally
determine the amount of the Normalized IBNR to be reflected on the Final Balance
Sheet. The cost of the Actuary shall be borne equally between Buyer and Seller.

         (c)  The value of the PPE and the Real Estate as reflected on the
Preliminary Balance Sheet shall not be adjusted and shall remain unchanged for
the purposes of the Final Balance Sheet; provided, however, that Buyer and
Seller acknowledge and agree that, if any parcel of the Real Estate is sold
prior to Closing, the Final Balance Sheet shall be adjusted only to (i) increase
the Cash by the amount of the sale proceeds, and (ii) reduce the value of the
Real Estate by such sale proceeds.

         (d)  Any capitalized terms used in this Section 10.6 which are not
defined in this Section 10.6 or in Section 1.1 above shall be as described on
the Preliminary Balance Sheet.

    10.7 ADJUSTMENTS TO THE COMPANY'S HMO MEMBERS. The number of the Company's
HMO members reflected on the February Enrollment Report will be reviewed and
evaluated during the forty-five (45) days following the Closing to determine the
actual number of HMO members enrolled in the Company's HMO as of February 1,
1997. The number of Adjusted Members will be determined by adjusting the number
of HMO members reflected on the February Enrollment Report to take into account
retroactive additions to the HMO membership and retroactive disenrollments from
the HMO membership. Adjusted Members shall include only those HMO members who,
on February 1, 1997, (i) were properly enrolled as a subscriber or dependent of
a subscriber in one of the Company's health benefit plans, (ii) satisfied all
the eligibility requirements for membership in that health benefit plan, (iii)
paid all applicable premiums and (iv) had not (a) been terminated by the
Company's HMO, or (b) voluntarily terminated membership in the Company's HMO.
The adjustments to the February Enrollment Report will be based upon the best
information available to the Company from internal and governmental sources
during the 45-day review period. Buyer and Seller shall work cooperatively and
diligently, and in good faith, to determine the number of Adjusted Members based
upon this information. At the end of the 45-day review period, Buyer shall cause
the Company to generate an updated February Enrollment Report to reflect the
retroactive additions to, or disenrollments from, the Company's HMO membership
as mutually agreed to by Buyer and Seller and this updated report shall be the
basis for the number of Adjusted Members and shall be final, binding and
conclusive upon the parties.

    10.8 INFORMATION SYSTEMS AGREEMENT. After the Closing, the Company, Buyer
or Buyer's affiliated management company will use and license from Seller the
information systems, software and services described on Exhibit "C" in
accordance with the I S Terms. Buyer shall cause full compliance with the I S
Terms and shall promptly pay to Seller all fees in connection with the services
provided by Seller.
    
    10.9 EXPENSES. Buyer and Seller each shall pay its own expenses (including
fees of any attorneys, accountants, brokers or other professionals engaged by

stock of the Company, and Seller has agreed to purchase the capital stock of the

First Amendment.

    NOW, THEREFORE, in consideration of the above premises and the promises,
covenants, conditions, representations and warranties exchanged by the parties
hereinbelow, Buyer and Seller hereby agree as follows:

    1.   AMENDMENTS TO THE AGREEMENT.   Buyer and Seller agree to amend the

    of Real Estate which are owned or held by the Company, Buyer or one of
    their subsidiaries or affiliates at the end of the Regulatory
    Negotiation Period, the depreciated book value of such parcels; plus
    (ii) with respect to those parcels of Real Estate which have been sold

         REGULATORY NEGOTIATION PERIOD:  The thirty (30) day period which
    follows (if applicable) the earlier to occur of (i) DOI's final and
    nonappealable rejection or disapproval of Buyer's completed application for

    has submitted its completed application for HMO Regulatory Approval without
    having obtained such approval."

         1.2  Article 1, Section 1.1, entitled DEFINED TERMS, is further
    amended by deleting the definition of "Assets" in its entirety and
    substituting the following definition therefor:

         "ASSETS:  The assets, properties, business, goodwill and rights

    Subsidiaries, except for the (i) Excluded Claims, (ii) the items
    listed in the last column of Schedule 2.4 entitled "Balances Retained
    by PacifiCare"; and (iii) account number 22072, entitled Accrued

    account was inadvertently excluded from the "Balances Retained by

    amended by deleting the definition of "Closing Date" in its entirety and
    substituting the following definition therefor:

         "CLOSING DATE:  February 21, 1997."

    substituting the following definition therefor:

         "PURCHASE REFUND:  To compensate Buyer for the deterioration in
    the value of the Company due to the Company's projected losses in the
    month of February, 1997, the Preliminary Purchase Price shall be
    reduced by an amount equal the product of (i) Four Hundred Thousand
    Dollars ($400,000.00), multiplied by (ii) a fraction the numerator of
    which is the number of days which


                                         -2-

<PAGE>

    have elapsed in the month of February through the Closing Date and 
    the denominator of which is twenty-eight (28), the number of days 
    in the month of February."

         1.5  Article 2 is amended by adding a new Section 2.7 as follows:

         "2.7 SUBSEQUENT HMO REGULATORY APPROVAL.  Without limiting any
    other provision of this Agreement, the purchase and sale of the
    Company's Shares as contemplated hereunder is subject to Buyer
    obtaining HMO Regulatory Approval as a condition subsequent to such
    transaction.  Buyer's inability to obtain HMO Regulatory Approval
    shall result in a rescission of the purchase and sale of the Shares in
    accordance with the provisions of Section 10.10 below."

         1.6  Article 6, Section 6.1, entitled REPRESENTATIONS AND WARRANTIES
TRUE; CLOSING CONDITIONS SATISFIED, is amended by (1) deleting the first clause

Article 6 have been fully satisfied by Seller or waived in writing by Buyer."

         1.7  Article 6, Section 6.4, entitled CONSENTS AND APPROVALS, is

satisfied by Buyer or waived in writing by Seller."

         1.9  Article 7, Section 7.4, entitled CONSENTS AND APPROVALS, is
amended by deleting the first sentence thereof in its entirety.  The deleted
sentence read as follows:  "HMO Regulatory Approval shall have been obtained."

         1.10 Article 10 is amended by adding the following provisions at the

    "After the Closing, Buyer shall fully cooperate with any appropriate
    requests made by Seller or others to review, copy or otherwise
    duplicate any books, records or other written materials or information
    respecting the conduct of the


                                         -3-

<PAGE>

    Company's business which may be reasonably necessary under the
    circumstances."

         1.11 Article 10 is amended by adding new Sections 10.11 and Section
10.12 as follows:

         "10.11    SEEKING HMO REGULATORY APPROVAL. (a) Seller shall use
    its best good faith efforts to continue to seek and to diligently
    pursue HMO Regulatory Approval.  In connection with its pending
    application for HMO Regulatory Approval, Buyer shall, and shall cause
    the Company to, promptly respond to all governmental requests for
    additional information and comments to the application.  Buyer shall,
    and shall cause the Company to, provide DOI or AHCA with all
    information and documentation necessary to obtain HMO Regulatory
    Approval.  Buyer shall comply with all reasonable regulatory
    requirements of DOI or AHCA in obtaining regulatory approval.

              (b)  During the continued pendency of HMO Regulatory
    Approval, Buyer shall preserve the Company's value and shall comply
    with the remaining obligations of this Section 10.11(b).  Buyer shall
    promote the Company's HMO business and market the Company's health
    benefit plans.  Buyer shall use reasonable and customary business and
    financial practices to enhance the Company's value and to preserve the
    Company's financial condition.  Buyer shall cause the Company to be
    operated in compliance with applicable regulatory and other laws.

              (c)  In the event that HMO Regulatory Approval cannot be
    obtained prior to January 31, 1998 or, prior to such time, DOI has
    rendered a final and nonappealable order disapproving or rejecting
    such completed application, then Buyer and Seller shall work
    cooperatively, diligently and in good faith during the Regulatory
    Negotiation Period to persuade DOI and/or AHCA to provide HMO
    Regulatory Approval.  If HMO Regulatory Approval has not been obtained
    prior to the expiration of the Regulatory Negotiation Period, then
    Buyer shall have the option (the "Put Option") to cause Seller to
    repurchase the Shares in exchange for the Put Option Price; provided,
    however, that Buyer's right to exercise the Put Option is conditioned
    upon satisfaction of the following obligations:

                   (i)  Buyer shall have complied with its obligations
    under Section 10.11(a) and 10.11(b) with respect to obtaining HMO
    Regulatory Approval and the conduct of the Company's business;


                                         -4-

<PAGE>

                   (ii) The Tangible Net Equity of the Company as of the
    end of the Regulatory Negotiation Period shall not be less than the
    Adjusted Real Estate Value; and

                   (iii)     Buyer agrees to and shall be solely
    responsible for and shall defend, indemnify and hold harmless Seller
    and Seller's shareholders, directors, officers, subsidiaries,
    affiliates, successors, successors-in-interest and assigns from and
    against:   (A) any balance sheet liabilities necessary to increase the
    Company's Tangible Net Equity to the Adjusted Real Estate Value; and
    (B) any other Liabilities of the Company or of any of its Subsidiaries
    which have arisen, occurred or accrued from and after the Closing Date
    through the date of repurchase of the Shares by Seller.

                   Provided that the conditions in the foregoing clauses
    (i), (ii) and (iii) are satisfied, then, upon the conditions described
    in this Section 10.11(c), including Buyer's timely exercise of the Put
    Option, Seller shall be required to repurchase the Shares for the Put
    Option Price.  Seller shall be required to effect such repurchase
    within ten (10) business days after Buyer's proper exercise of the Put
    Option.  Upon Buyer's exercise of the Put Option, the Put Option
    Price, in Seller's sole discretion, may be reduced by any known
    balance sheet liabilities or other known Liabilities of the Company
    for which Buyer has agreed to indemnify Seller pursuant to clause
    (iii) of this Section 10.11(c).  The covenants and obligations of this
    Section 10.11 shall survive the Closing.

         10.12     OTHER NOTICES, CONSENTS AND APPROVALS.  In the event
    that any notices to, or filings or registrations with, Governmental
    Authorities or other Persons necessary to consummate the purchase and
    sale of the Shares as contemplated hereunder were not given or made
    prior to Closing, then Buyer and Seller, as the case may be, shall
    provide such notice or make such filings or registrations as soon
    after Closing as possible.   In the event that any consents or
    approvals, other than HMO Regulatory Approval, necessary to, or
    contemplated by, the purchase and sale of the Shares hereunder were
    not obtained prior to Closing ("Other Consents"), Buyer shall
    diligently continue to use its best good faith efforts to obtain such
    Other Consents as expeditiously as possible.  In order to obtain such
    Other Consents, Buyer shall, or shall cause the Company to, comply
    with all requests for information and all other reasonable requests
    required by the Person whose consent or approval is required.  Buyer
    acknowledges that Seller has, prior to the Closing, provided Buyer
    with copies of all requests for the Other Consents required to be
    obtained on Seller's part to consummate the transactions contemplated
    hereunder.  The covenants and obligations of this Section 10.12 shall
    survive the Closing.
