Adair ("Adair"), Gloria L. Austin ("Austin"), William P. Bracciodieta ("Bracciodieta"), Larry L. Georgopolous ("Georgopolous"), Gary E. Goldstein, M.D. ("Goldstein"), Richard D. Jacobs ("Jacobs"), R. Judd Jessup ("Jessup"), Jack D. Massimino ("Massimino"), Barbara C. McNutt ("McNutt"), Kenneth S. Ord ("Ord"), Westcott W. Price III ("Price"), Walter R. Stone ("Stone"), Margaret Van Meter ("Van Meter"), and Michael J. Weinstock ("Weinstock"). In this Agreement, Adair, Austin, Bracciodieta, Georgopolous, Goldstein, Jacobs, Jessup, Massimino, McNutt, Ord, Price, Stone, Van Meter and Weinstock are referred to individually as a "Management Investor" and collectively as the "Management Investors." A. WHEREAS, FHP has formed the Company to function as a physician practice management company to provide practice management services to certain professional corporations; and B. WHEREAS, FHP has acquired 9,100,000 shares of the Class A Voting Common Stock of the Company, par value $.01 (one cent) per share (the "Class A Common Stock"), which shares of Class A Common Stock comprise all of the issued and outstanding shares of Class A Common Stock of the Company, for consideration in the amount of $91,000.00; and C. WHEREAS, the Company and FHP regard the services provided to the Company by the Management Investors as valuable to the Company and FHP, and have determined that it would be to the advantage and in the best interests of the Company and FHP to provide for the issuance of shares of Class B Common Stock of the Company, par value $.01 (one cent) per share (the "Class B Common Stock," with the Class A Common Stock and the Class B Common Stock collectively referred to herein as the "Common Stock"), to the Management Investors as provided for in this Agreement (i) as an inducement to remain in the service of the Company and FHP, and (ii) as an incentive for increased efforts during such service; and D. WHEREAS, FHP desires to provide for the issuance of shares of Class B Common Stock of the Company to the Management Investors, and the Management Investors wish to acquire such shares from the Company, all on the terms and subject to the conditions set forth in this Agreement. NOW, THEREFORE, in consideration of the mutual promises, representations, warranties, covenants and conditions set forth in this Agreement, and for other good and valuable consideration, the receipt of which is hereby acknowledged, the parties to this Agreement mutually agree as follows: 1. DEFINITIONS. 1.1 ACCOUNTING TERMS. In this Agreement, "GAAP" means generally accepted accounting principles, consistently applied. All accounting terms not specifically defined herein shall be construed in accordance with GAAP. 1.2 TERMS GENERALLY. The definitions in this Agreement shall apply equally to both the singular and plural forms of the terms defined. Whenever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms. The words "include", "includes" and "including" shall be deemed to be followed by the phrase "without limitation" if such phrase does not actually appear. The headings of Sections are inserted for convenience of reference only and are not intended to be a part of or to affect the meaning or interpretation of this Agreement. Unless the context shall otherwise require, any reference to any agreement or other instrument or statute or regulation is to it as amended and supplemented from time to time (and, in the case of a statute or regulation, to any successor provision). Any reference in this Agreement to a "day" or a number of "days" (without the explicit qualification of "business") shall be interpreted as a reference to a calendar day or number of calendar days. If any action or notice is to be taken or given on or by a particular calendar day, and such calendar day is not a business day, then such action or notice shall be deferred until, or may be taken or given, on the next business day. 2. PURCHASE AND SALE OF STOCK. 2.1 PURCHASE AND SALE. Subject to the terms and conditions of this Agreement, each of the Management Investors, severally and not jointly, agrees to purchase, and FHP agrees to cause the Company to, and the Company agrees to, issue, sell and transfer to each of the Management Investors, severally and not jointly, at the Closing (as defined below), for consideration in the amount of $.01 (one cent) per share, the following: as to each such Management Investor, the number of shares of the Class B Common Stock of the Company (the "Stock") set forth in that certain schedule signed by each of FHP, the Company, and such Management Investor (each, a "Management Investor Schedule"). The aggregate number of shares of Stock issued to the Management Investors shall be 900,000, and the Stock issued to the Management Investors, collectively, initially shall comprise 9% of the total outstanding Common Stock of the Company (the "Management Stock"). Stock certificates evidencing the Management Stock, in addition to blank stock 2 powers executed by each Management Investor, initially shall be held by the Assistant Secretary of FHP (the "Escrow Holder"), and shall continue to be held by the Escrow Holder for the periods set forth in Section 3 below, subject to the rights and limitations set forth in this Agreement. All shares of Management Stock shall be fully paid and nonassessable shares. Except as otherwise provided in this Agreement, each Management Investor shall have all rights of a shareholder with respect to the Management Stock, including rights to vote, to receive dividends (including stock dividends), to participate in stock splits or other recapitalizations, and to exchange such shares in a merger, consolidation or other reorganization or exchange of shares. 2.2 CLOSING AND CLOSING DATE. The closing of the transactions contemplated by this Agreement (the "Closing") shall take place on the date ten (10) days following the date of the execution of this Agreement. 3. RESTRICTIONS. Subject to other limitations contained in this Agreement, the Management Investors shall not have any right to sell, give, pledge, hypothecate or otherwise transfer or dispose of any Management Stock (the "Restrictions") until the Restrictions lapse as provided in this Section 3. Prior to the lapse of the Restrictions, and subject to the provisions of Section 3.1 below, the Management Stock shall continue to be held in escrow by the Escrow Holder and shall be deemed to be "Restricted Securities." The Restrictions shall lapse, and the Management Stock (and a proportional amount of any Additional Securities (as defined herein)) shall vest, during the period commencing on the date of the Closing and ending on July 1, 1999 (the "Vesting Period") as follows: 3.1 The Restrictions imposed on the Restricted Securities under this Section 3 shall lapse as to 25% of the shares of the Management Stock issued to each Management Investor on July 1 of each year during the Vesting Period. Upon the lapse of the Restrictions on shares of the Management Stock, such shares shall cease to be Restricted Securities. Within thirty (30) days after the lapse of the Restrictions on shares of the Management Stock, the Escrow Holder shall, upon receiving confirmation from the Company that the Management Investor's withholding obligations, if any, under Section 8 of this Agreement have been satisfied, transmit to the Management Investor the certificates evidencing those shares of Management Stock with respect to which the Restrictions have lapsed; PROVIDED, HOWEVER, that certificates representing shares of Management Stock which are subject to a Performance Purchase Option under Section 5.3, below, shall not be released from escrow until such time as the applicable Performance Purchase Option has expired without having been exercised. 3 3.2 The occurrence of a change in control of the Company or FHP shall not be an event which causes Restrictions imposed upon and remaining applicable to Management Stock to terminate. 4. ADDITIONAL SECURITIES. Any securities received as the result of ownership of Restricted Securities ("Additional Securities"), including, without limitation, securities received as a stock dividend or stock split, or as a result of a merger, consolidation, recapitalization or reorganization, shall be held by the Escrow Holder in the same manner and subject to the same conditions as the Restricted Securities with respect to which they were issued. Each Management Investor shall be entitled to direct the Escrow Holder to exercise any warrant or option received as Additional Securities upon supplying the funds necessary to do so, in which event the securities so purchased shall constitute Additional Securities. In the event any Restricted Securities or Additional Securities consist of a security by its terms or otherwise convertible or exchangeable for another security at the election of the holder thereof, each Management Investor may exercise any such right or conversion or exchange, and any securities so acquired shall be deemed Additional Securities. 5. FHP OPTIONS TO PURCHASE. Notwithstanding the foregoing, the Management Stock held by the Management Investors shall be subject to the following terms: 5.1 OPTIONS RELATED TO TERMINATION OF EMPLOYMENT. Prior to the lapse of the Restrictions on any Restricted Securities, and upon such time as a Management Investor ceases to be employed by one of the Company, FHP, or an Affiliate (as defined below) of FHP, FHP shall have the option to purchase from such Management Investor, and such Management Investor shall be obligated to sell to FHP, for consideration in the amount of $.01 (one cent) per share (subject to Section 5.5, below), all or any portion of such Restricted Securities (including any Additional Securities issued in respect of such Restricted Securities) at the date of such termination of employment. As used herein, an "Affiliate" of a Person (as defined in Section 9.2(a), below) shall mean a Person controlling, under common control with or controlled by such Person. 5.2 UNRESTRICTED OPTION. At any time prior to October 1, 1999, FHP shall have the option to purchase from any Management Investor(s), and such Management Investor(s) shall be obligated to sell to FHP, any or all of the Management Stock, together with any Additional Securities issued in respect of such Management Stock, of such Management Investor(s), at a price per share of $30.00 (subject to Section 5.5, below). 4 5.3 PERFORMANCE OPTIONS. FHP shall have the option to purchase from any Management Investor(s), and such Management Investor(s) shall be obligated to sell to FHP, for consideration in the amount of $.01 (one cent) per share (subject to Section 5.5, below), certain amounts of the Management Stock, together with any Additional Securities issued in respect of such Management Stock, under the following circumstances (the "Performance Purchase Options"): (a) If the Company fails to meet the Financial Goal, as adjusted, for the fiscal year 1996, as approved by the Audit Committee of FHP's Board of Directors (the "Audit Committee") in accordance with the procedures outlined in Section 5.3(d) below, FHP shall have the option to purchase from each Management Investor that portion of the Management Stock with respect to which the Restrictions lapsed on July 1, 1996 comprising 20% of the total amount of such Management Stock. (b) If the Company fails to meet the Financial Goal, as adjusted, for the fiscal year 1997, as approved by the Audit Committee in accordance with the procedures outlined in Section 5.3(d) below, FHP shall have the option to purchase from each Management Investor that portion of the Management Stock with respect to which the Restrictions lapsed on July 1, 1997 comprising 20% of the total amount of such Management Stock. (c) If the Company fails to meet the Financial Goal, as adjusted, for the fiscal year 1998, as approved by the Audit Committee in accordance with the procedures outlined in Section 5.3(d) below, FHP shall have the option to purchase from each Management Investor up to an additional 20% of the total amount of Management Stock pursuant to the following formula: for every $100,000 below the amount which is $4 million below the Financial Goal, FHP shall have the option to purchase from each Management Investor 0.5% of the total amount of such person's Management Stock. For example, if the Company's fiscal year 1998 results are $7 million below the Financial Goal for the fiscal year 1998, FHP may purchase additionally that portion of the Management Stock with respect to which the Restrictions lapsed on July 1, 1998 comprising 15% of the total amount of such Management Stock. (d) The Financial Goals for the fiscal years 1996, 1997 and 1988 shall be as approved by the Audit Committee in accordance with the following guidelines: The Financial Goal for fiscal year 1996 will be a pretax loss of $21,784,000 (after allocation of FHP corporate charges and after net interest income or expense). This pretax loss assumes that the Fountain Valley Hospital, Salt Lake City 5 Hospital, and Westminster subacute facility (collectively the "Hospitals") were sold on July 1, 1995. The Financial Goal for fiscal year 1996 will be adjusted to reflect the following: (i) an adjustment will be made to include the budget of daily operating expenses for every day the Hospitals are not sold during the fiscal year (the daily expenses to be added to budget are as follows: Fountain Valley - $35,271, Utah Hospital - $21,271, and Westminster subacute - $10,000); (ii) an adjustment will be made to reflect interest on any debt incurred in connection with the formation of the Company or lease expenses in excess of depreciation for assets leased from FHP or its subsidiaries. The Financial Goal for fiscal year 1997 will be equivalent to the Financial Goal for fiscal year 1996 (a pretax loss of $21,784,000) adjusted to reflect (x) the annual impact of adjustments under clause (ii) above and (y) an improvement of $20,000,000. The Financial Goal for fiscal year 1998 will be the Financial Goal for fiscal year 1997 plus an improvement of $20,000,000. The determination of the Financial Goal for fiscal year 1996 will be approved by the Audit Committee, and the initial determination of the Financial Goals for fiscal year 1997 and 1998 will be approved by the Audit Committee prior to July 1, 1996, and July 1, 1997, respectively. The Audit Committee may, in its sole discretion exercised in good faith, adjust the Financial Goals if it determines that such adjustment is necessary or desirable to accomplish the purposes of this Agreement. The determination as to whether the Company has met the Financial Goal for any particular fiscal year shall be made by the Audit Committee within 90 days after the end of such fiscal year (as to each fiscal year, the "Determination Date"). The determinations of the Audit Committee shall be conclusive and binding upon the parties in all respects. 5.4 MECHANICS OF OPTION EXERCISE. (a) An option granted under Sections 5.1 or 5.2 hereof shall be exercised by FHP upon 30 days' prior written notice to such effect to the Management Investor(s) whose shares are subject to the option. (b) With respect to each Performance Purchase Option granted under Section 5.3 hereof, FHP shall have 90 days from the Determination Date for such fiscal year within which to exercise the Performance Purchase Option for that fiscal year. (c) In the event that an option under this Section 5 is exercised, the total purchase price for such shares shall be paid by bank check at the time the certificate or certificates evidencing the shares involved are delivered. Delivery of the certificate or certificates 6 evidencing the shares involved, properly endorsed, shall be made, against payment therefor, immediately after the date of exercise of the option granted under this Section 5, or such other time as may be agreed upon by the parties to such transaction. 5.5 CERTAIN ADJUSTMENTS. The Audit Committee may, in its sole discretion exercised in good faith, adjust the number of shares of Management Stock that may be purchased by FHP at any time upon the exercise of the options provided in this Section 5, and the purchase price per share pursuant thereto, if it determines that such adjustment is equitably required to prevent the dilution or enlargement of the rights of FHP or the Management Investors, as appropriate, that otherwise would result from any stock dividend, stock split, combination of shares, recapitalization or other change in capital structure of the Company, merger, consolidation, spin-off, reorganization, partial or complete liquidation, issuance of rights or warrants to purchase securities, or any other corporate transaction or event having an effect similar to any of the foregoing. 6. DRAG-ALONG RIGHTS AND TAG-ALONG RIGHTS. The provisions of this Section 6 shall expire at such time as there has been sold or distributed to the public in a spin-off or in one or more underwritten public offerings pursuant to one or more Registration Statements (as defined in Section 7) filed with, and declared effective by, the Commission under the Securities Act (both as defined in Section 7) an aggregate number of shares of the Common Stock of the Company equal to at least twenty percent (20%) of the Common Stock of the Company outstanding after the last such public offering. 6.1 DRAG-ALONG RIGHTS. If FHP proposes a transaction which would involve the sale or other transfer for consideration by FHP of an amount of shares of Common Stock of the Company, which, if completed, would result in a person or entity (other than FHP or its direct or indirect subsidiaries or affiliates) acquiring 80% or more of the shares of the outstanding Common Stock of the Company held by FHP (a "Proposed Transaction"), then FHP shall give written notice (a "Transaction Notice") to the Management Investors describing the material terms of the Proposed Transaction. FHP shall be entitled to require each Management Investor to include in such Proposed Transaction all of such Management Investor's shares of Management Stock; PROVIDED, HOWEVER, that no Management Investor shall be required to enter into any Proposed Transaction pursuant to this Section 6.1 unless the terms and conditions of the Proposed Transaction provide that either (a) such Management Investor will not be required to participate in any indemnification of the buyer or buyers, or (b) if such Management Investor will participate in such indemnification, (i) such Management Investor's liability 7 will be several and not joint and several, and (ii) such Management Investor's liability will be capped at the market value, determined at the time of receipt, of the net pre-tax proceeds to be received by such Management Investor pursuant to the terms of the Proposed Transaction. 6.2 TAG-ALONG RIGHTS. In connection with any Proposed Transaction, each Management Investor shall have a right to include in such Proposed Transaction up to the number of shares of Management Stock computed by multiplying (i) the total number of shares of Common Stock of the Company proposed to be sold or otherwise disposed of by FHP pursuant to the Proposed Transaction by (ii) a fraction, the numerator of which shall equal the aggregate number of shares of Management Stock owned by such Management Investor and which are no longer subject to the Restrictions provided for in Section 3 or the Performance Options provided for in Section 5.3 as of the close of business on the day immediately preceding the date of the Transaction Notice and the denominator of which shall equal the sum of the aggregate number of shares of the Common Stock of the Company issued and outstanding on a fully diluted basis on such date. Any Management Investor desiring to exercise his or her tag-along right must deliver a written notice of exercise to FHP within 10 days after the date FHP gives the Transaction Notice to such Management Investors. 6.3 SAME TERMS AND CONDITIONS. In the case of both the drag-along rights described in Section 6.1 and the tag-along rights described in Section 6.2, a sale of Management Stock by a Management Investor shall be at the same price per share (in both amount and purchase medium) applicable to the sale of the shares of Common Stock of the Company by FHP and otherwise shall be on terms and conditions at least as favorable as those applicable to FHP. 7. REGISTRATION RIGHTS. 7.1 CERTAIN DEFINITIONS. As used in this Section 7 and elsewhere in this Agreement, the following terms shall have the following respective meanings: (a) "Commission" shall mean the Securities and Exchange Commission or any other Federal agency at the time administering the Securities Act; (b) "Exchange Act" shall mean the Securities Exchange Act of 1934, or any similar Federal statute, and the rules and regulations of the Commission thereunder, all as the same shall be in effect at the time; (c) "Registrable Securities" shall mean all Management Stock and Additional Securities held by the Management Investors which are no longer subject to the restrictions specified in Section 3 or the purchase options granted to FHP under Section 5; (d) "Securities Act" shall mean the Securities Act of 1933, or any similar Federal statute, and the rules and regulations 8 of the Commission thereunder, all as the same shall be in effect at the time; and (e) The terms "register," "registered" and "registration" refer to a registration effected by preparing and filing a registration statement or similar document in compliance with the Securities Act, and the declaration or ordering of effectiveness of such registration statement or document. 7.2 INCIDENTAL REGISTRATION. (a) RIGHT TO INCLUDE REGISTRABLE SECURITIES. If the Company proposes to register any of its Common Stock under the Securities Act (other than by a registration on Form S-4 or S-8 or any successor or similar forms or filed in connection with an exchange offer or any offering of securities solely to the Company's existing stockholders), whether or not for sale for its own account, the Company will each such time give written notice thereof to all Management Investors and, upon the written request of any Management Investor made within 20 days after the receipt of any such notice, the Company will use its best efforts to effect the registration under the Securities Act of the Registrable Securities for which the Management Investor(s) has requested registration thereof; PROVIDED, HOWEVER, that if the Company shall determine for any reason (i) not to register such securities, then the Company shall be relieved of its obligation to use best efforts to effect registration of the Registrable Securities, or (ii) to delay registration of such securities, then the Company shall be permitted to delay registering any Registrable Securities. (b) PRIORITY IN INCIDENTAL REGISTRATIONS. If a registration pursuant to this Section 7 involves an underwritten offering, and the managing underwriter shall advise the Company that, in its opinion, the number of securities requested and otherwise proposed to be included in such registration exceeds the number which can be sold in such offering within a price range acceptable to the Company, the Company will include in such registration, to the extent of the number which the Company is so advised can be sold in such offering, (i) first, all securities proposed to be sold by the Company, (ii) second, all securities proposed to be sold by FHP, and (iii) third, the number of Registrable Securities requested to be included in such registration by the Management Investors and securities of other persons requested to be included in such registration that, in the opinion of such managing underwriter, can be sold, such amount to be allocated among all such Management Investors and other persons pro rata based upon the respective number of securities each such person has requested to be included in such registration. 9 (c) SELLER INFORMATION; SUSPENSION. The Company may require each seller of Registrable Securities to furnish the Company such information regarding such seller and the distribution of such securities as the Company may from time to time reasonably request. Notwithstanding any other provision of this Agreement, the Management Investors understand that there may be periods during which the Company may determine, in good faith, that it is in the best interest of the Company and its stockholders to defer disclosure of any material facts regarding the Company business which the Company requires for reasonable business purposes to remain confidential (collectively, "Non-Public Information"), until such information has reached a more advanced stage and that during such periods sales of Registrable Securities and the effectiveness of any registration statement covering Registrable Securities may be suspended or delayed. Each Management Investor agrees by acquisition of such Registrable Securities that upon receipt of any notice from the Company of (i) the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made, or (ii) the development of any Non-Public Information, then such Management Investor will forthwith discontinue such Management Investor's disposition of Registrable Securities pursuant to the registration statement relating to such Registrable Securities. 7.3 UNDERWRITTEN OFFERINGS; LOCKUP. In connection with any distribution by one or more underwriters of the Company's securities registered pursuant to this Section 7, to the extent not inconsistent with applicable law, each Management Investor agrees as a condition to such Management Investor's rights under this Agreement not to effect any public sale or distribution of any equity securities of the Company, or any securities convertible into or exchangeable or exercisable for such securities, including a sale pursuant to Rule 144 under the Securities Act (or any similar provision then in force), during such period as may be agreed to between the Company and the underwriters, except as part of such underwritten registration. 7.4 INDEMNIFICATION/INDEMNIFICATION AGREEMENTS. Notwithstanding the foregoing, the Company may require, as a condition to including any Management Investor's Registrable Securities in any registration statement filed pursuant to this Sections 7, that each Management Investor who has requested that his or her Registrable Securities be included in such registration statement enter into an indemnification agreement 10 with the Company on terms and conditions customary for indemnification agreements in connection with transactions of this type. 7.5 TERMINATION OF REGISTRATION RIGHTS. The registration rights granted to the Management Investors pursuant to this Section 7 shall terminate: (a) As to any particular Registrable Securities, at the time that such Registrable Securities can be sold by the Management Investor holding such Registrable Securities pursuant to Rule 144 or successor rules without the necessity for registration; (b) Upon transfer by the Management Investor of such Registrable Securities; and (c) In any event, ten years from the date of this Agreement. 7.6 REGISTRATION EXPENSES. All expenses incurred by the Company incident to the Company's performance of or compliance with this Section 7, including, without limitation, all registration and filing fees, fees and expenses of compliance with state securities or blue sky laws, printing expenses and fees and disbursements of counsel for the Company and all independent public accountants (including the expenses of any audit), but excluding underwriting commissions, and discounts and expenses agreed to be paid to underwriters (all such expenses being herein called "Registration Expenses"), shall be borne by the Company. 8. WITHHOLDING. The Management Investors acknowledge that the Company may withhold compensation (in cash, or, at the Company's option, in stock) to satisfy all applicable federal, state, and local income, employment and other tax withholding requirements. 9. REPRESENTATIONS, WARRANTIES AND AGREEMENTS. 9.1 AUTHORIZATION. FHP and each Management Investor represent and warrants that this Agreement, when executed and delivered by each of them, will constitute a valid and legally binding obligation of each of them, enforceable against each of them in accordance with its terms. 9.2 INVESTMENT REPRESENTATIONS. (a) This Agreement is made with the Management Investors in reliance upon each Management Investor's representation to the Company and to FHP, which by such Management Investor's execution and delivery hereof each Management Investor hereby confirms, that the shares of the Management Stock to be received by such Management Investor will be acquired for investment for such Management Investor's own account, not as a nominee or agent, and not with a view to the sale in connection with a public distribution of any part thereof; and (ii) such Management Investor has no present intention of selling, granting a 11 participation in or otherwise distributing, and does not have any contract, undertaking, agreement or arrangement with any natural person, corporation, partnership, association or other entity ("Person") to sell, transfer or grant a participation to such Person, or to any third Person, with respect to any of the shares of the Management Stock. (b) Each Management Investor understands that the Management Stock has not been registered under the Securities Act on the ground that the sale and the issuance of Management Stock hereunder is exempt from registration under the Securities Act pursuant to Section 4(2) thereof and regulations issued thereunder, and that FHP's and the Company's reliance on such exemption is predicated on the Management Investors' representations set forth herein. (c) Each Management Investor represents that such Management Investor is an executive officer or director of the Company or FHP. Each Management Investor further represents that, during the course of the transaction and prior to such Management Investor's purchase of shares of the Management Stock, such Management Investor had access to, the opportunity to ask questions of, and receive answers from, representatives of FHP and the Company concerning the terms and conditions of the offering and to obtain additional information (to the extent FHP or the Company possessed such information or could acquire it without unreasonable effort or expense) necessary to verify the accuracy of any information furnished to such Management Investor or to which such Management Investor had access. (d) Each Management Investor has relied solely on its own investigations in making a decision to purchase the Management Stock, and has received no representation or warranty from FHP or the Company, or any of the affiliates, employees or agents of either. (e) Each Management Investor understands that the Management Stock may not be sold, transferred or otherwise disposed of without registration or qualification under the Securities Act and the California Corporate Securities Law of 1968, as amended (the "CSL") or pursuant to an exemption therefrom, and that in the absence of an effective registration statement and permit covering the Management Stock or an available exemption from registration under the Securities Act and qualification under the CSL, the Management Stock must be held indefinitely. Each Management Investor represents that, in the absence of such an effective registration statement and permit covering the Management Stock, such Management Investor will sell, transfer or otherwise dispose of the Management Stock only in a manner consistent with his or its representations set 12 forth herein and then only in accordance with the provisions of this Agreement and applicable laws and regulations. (f) Each Management Investor agrees that, except as specifically contemplated hereunder, in no event will such Management Investor transfer or dispose of any of the Management Stock other than pursuant to an effective registration statement under the Securities Act, unless and until (i) there is compliance with all requirements contained in other sections of this Agreement; (ii) the Management Investor shall have notified the Company of the proposed disposition and shall have furnished the Company with a statement of the circumstances surrounding the disposition; (iii) if requested by the Company, at the expense of the Management Investor or transferee, such Management Investor shall have furnished to the Company an opinion of counsel, reasonably satisfactory to the Company, to the effect that such transfer may be consummated without registration under the Securities Act; and (iv) the transferee executes and delivers an assumption agreement, in form and substance satisfactory to FHP, by which the transferee assumes all obligations of a Management Investor under this Agreement. 9.3 LEGENDS; STOP TRANSFER.

CERTAIN COVENANTS. 10.1 RIGHT OF FIRST REFUSAL. The provisions of this Section 10 shall expire at such time as there has been sold or distributed to the public in a spin-off or in one or more underwritten public offerings pursuant to one or more Registration Statements filed with, and declared effective by, the Commission under the Securities Act. (a) Each Management Investor agrees that such Management Investor will not sell or otherwise dispose of all or any portion of the Management Stock held by such Management Investor unless such sale or disposition (i) involves only those shares of Management Stock (a) with respect to which the Restrictions have lapsed, and (b) are no longer subject to any of the options provided in Section 5 hereof, and (ii) is made (a) for consideration that is payable in cash or cash equivalents at the time of sale, (b) only in strict accordance with and after full compliance with the provisions of this Section 10.1, and (c) pursuant to a good faith offer to purchase such Management Stock in writing from a responsible third party. In the event of any such proposed sale or other disposition, the Management Investor proposing to make such sale or other disposition (the "Selling Investor") will give notice to the Company and 14 concurrently to FHP containing a complete description of the transaction proposed (the "Proposal"), including the number of shares of Management Stock proposed to be sold or otherwise disposed of (the "Transfer Shares"), the consideration to be paid per Transfer Share and the names of all other parties to, and all other material terms of, the proposed transaction, and a copy of the written offer from the third party. (b) For a period of thirty (30) business days after delivery of the Proposal (the "FHP Option Period"), FHP shall have the sole and exclusive right to purchase all or any portion of the Transfer Shares owned by the Selling Investor for the consideration stated in the Proposal and on such other terms and conditions as those offered to the Selling Investor as set forth in the Proposal. (c) If within the FHP Option Period FHP does not exercise the option provided in subsection (b) above as to all of the Transfer Shares, then for a period of ten (10) days (the "Company Option Period") commencing upon the expiration of the FHP Option Period (or such earlier time as FHP has either given notice of exercise pursuant to (e) below or has advised the Selling Investor that it does not intend to exercise such option), the Company shall have the sole and exclusive right to purchase all or any portion of the remaining Transfer Shares for the consideration and on the other terms and conditions set forth in the Proposal. (d) After expiration of the FHP Option Period and the Company Option Period, if FHP and the Company have not exercised their respective options so as to purchase, in the aggregate, all of the Transfer Shares proposed to be sold by the Selling Investor, then none of such Transfer Shares will be sold to either of said parties, and within a period ending sixty (60) days after the expiration of the Company Option Period, the Selling Investor may sell or otherwise dispose of the Transfer Shares as are the subject of the Proposal, but (i) only for cash or cash equivalents, and (ii) only in strict accordance with the terms and provisions set forth in the Proposal. (e) Any option granted under this Section 10.1 may be exercised by notice in writing to the Selling Investor and the Company stating that such option is exercised. (f) In the event that the options under this Section 10.1 have been exercised so as to purchase all of the Transfer Shares proposed to be sold by the Selling Investor, delivery of the certificate or certificates evidencing the Transfer Shares, properly endorsed, shall be made by the Selling Investor against payment therefor within 15 ten (10) days after the expiration of the Company Option Period at the principal office of the Company, unless a different time and place or both is agreed upon by the parties to such transaction, and the total purchase price with respect to such option shall be paid in the manner and at the time or times specified in the Proposal. (g) Notwithstanding anything to the contrary contained in this Agreement, a Management Investor shall be permitted to transfer those shares of such Management Investor's Management Stock with respect to which the Restrictions have lapsed, to a Permitted Transferee (as defined below) of such Management Investor. For purposes of this Agreement, "Permitted Transferee" shall mean (i) any member of the immediate family of such Management Investor, (ii) any trust, all of the beneficiaries of which are members of the immediate family of such Management Investor, or (iii) the estate or personal representative of such Management Investor if such Management Investor is deceased; PROVIDED, HOWEVER, that any Permitted Transferee to whom such shares of Management Stock are transferred pursuant to this paragraph (g) shall be required, as a condition of such transfer, to execute and deliver a written assumption agreement by which such assignee assumes all rights and obligations of a Management Investor under this Agreement, including but not limited to (i) the restrictions imposed by Sections 5 hereof, and (ii) the rights and obligations of FHP under Section 6 hereof. Any reference to a "Management Investor" contained in this Agreement shall be deemed to include such Management Investor's Permitted Transferees. 11. MISCELLANEOUS. 11.1 REMEDIES. The parties to this Agreement acknowledge and agree that breach of any of the covenants of FHP, the Company and the Management Investors set forth in this Agreement may not be compensable by payment of money damages and, therefore, that the covenants of FHP, the Company and the Management Investors set forth in this Agreement may be enforced in equity by a decree requiring specific performance. Without limiting the foregoing, if any dispute arises concerning the sale or other disposition of any of the Management Stock subject to this Agreement, the parties to this Agreement agree that an injunction may be issued restraining the sale or other disposition of such Management Stock or rescinding any such sale or other disposition, pending resolution of such controversy.

(3) Pursuant to this Amendment, (i) all rights and obligations created under the Stock Purchase Agreement between (a) FHP and the Management Investors with respect to the TMMC Management Stock, and (b) the Company and the Management Investors with respect to the TMMC Management Stock, shall hereby also create separate and identical rights and obligations between (x) FHP and the Management Investors with respect to the THSC Management Stock, and (y) THSC and the Management Investors with respect to the THSC Management Stock, respectively, as if two separate and identical sets of such rights and obligations were originally created thereunder, (ii) all other rights and obligations created under the Stock Purchase Agreement between (a) FHP and the Management Investors, and (b) the Company and the Management Investors, shall hereby also create separate and identical rights and obligations between (x) FHP and the Management Investors, and (y) THSC and the Management Investors, respectively, as if two separate and identical sets of such rights and obligations were originally created thereunder, (iii) all references in the Stock Purchase Agreement to "the Company," in so far as such references relate to such rights and obligations created between the Management Investors and the Company described in clauses (i)(b) and (ii)(b), shall also be references to THSC and shall relate to such separate and identical rights and obligations between the Management Investors and THSC as described in clauses (i)(y) and (ii)(y), above, and (iv) all other references to "the Company" in the Stock Purchase Agreement shall also be references to THSC; PROVIDED, HOWEVER, that the foregoing clauses (iii) and (iv) shall not apply to those references to "the Company" contained in Sections 5.1, 5.3, 8 and 11.5 of the Stock Purchase Agreement.

The Management Investors acknowledge that the Company, FHP or THSC, as appropriate, may withhold compensation (in cash, or, at the option of the Company, FHP or THSC, as appropriate, in stock) to satisfy all applicable federal, state, and local income, employment and other tax withholding requirements." (6) The parties hereto acknowledge that there exists the possibility that at some future date, THSC may be merged with or into the Company, and in the event such merger occurs, it is presently contemplated that upon the effective time of such merger (the "Effective Time"), each Management Investor shall receive, in exchange for the shares of THSC Common Stock purchased by such Management Investor pursuant to the Stock Purchase Agreement, as amended by this Amendment (or, in the event that THSC and the Company are merged into a new entity, for the shares of the THSC Common Stock and the shares of the TMMC Common Stock so purchased by such Management Investor), the number of shares of TMMC Common Stock (or shares of the common stock of the new entity) which, when combined with the number of shares of TMMC Common Stock purchased by such Management Investor pursuant to the Stock Purchase Agreement, as amended by this Amendment (or which shares of the common stock of the new entity), would result in the ownership by such Management Investor of the same percentage of the total outstanding common stock of the Company (or of such merged entity) immediately after the Effective Time as the percentage of the total outstanding common stock of the Company owned by such Management Investor immediately prior to the Effective Time. In such event, immediately following the Effective Time: (i) all rights and obligations created under this Amendment between (a) FHP and the Management Investors with respect to the THSC Management Stock, and (b) THSC and the Management Investors with respect to the THSC Management Stock, shall become rights and obligations between (x) FHP and the Management Investors with respect to the TMMC Management Stock, and (y) the Company and the Management Investors with respect to the TMMC Management Stock, respectively, as if the separate and identical obligations created pursuant to Section 1(a)(3)(i), above, had never been created thereunder; (ii) all other rights and obligations created pursuant to this Amendment between (a) FHP and the Management Investors, and (b) THSC and the Management Investors, shall become rights and obligations between (x) FHP and the Management Investors, and (y) the Company and the Management Investors, respectively, as if the separate and identical sets of rights and obligations created pursuant to Section 1(a)(3)(ii), above, had never been created thereunder; 4 (iii) all references in the Stock Purchase Agreement, as amended by this Amendment, to "the Company," in so far as such references relate to such rights and obligations created pursuant to Section 1(3)(a)(iii), above, between the Management Investors and THSC, shall be references only to the Company, and shall no longer be references to THSC, and shall relate only to the rights and obligations between the Management Investors and the Company as described in clauses (i)(y) and (ii)(y) of this Section 1(a)(6); and (iv) all other references to "the Company" in the Stock Purchase Agreement, as amended by this Amendment, shall be references to the Company only. Each Management Investor hereby agrees and consents that the execution of this Amendment by such Management Investor shall constitute an agreement by such Management Investor to (i) consent in writing to a merger of THSC with or into the Company pursuant to Section 228 of the Delaware General Corporation Law, as amended (the "DGCL"), and (ii) refrain from demanding any appraisal rights to which such Management Investor might otherwise be entitled pursuant to Section 262 of the DGCL, or pursuant to any other provision of applicable law, in connection with such a merger.

Bracciodieta" and "Bracciodieta" in the Stock Purchase Agreement. Accordingly, William P. Bracciodieta shall not be a party to the Stock Purchase Agreement. 2. NOTICES.

(b) EXPIRATION OF CERTAIN OPTIONS. At the Effective Time (as that term is defined in the Reorganization Agreement), the Stock Purchase Agreement shall be amended to add the following as Section 12: "12. EXPIRATION OF CERTAIN OPTIONS. Notwithstanding anything to the contrary contained in this Agreement (including, without limitation, the provisions of Sections 3.2 and 5.4, above): 12.1 TERMINATION OF FHP MANAGEMENT INVESTORS WITHOUT CAUSE. In the event that the employment with FHP of any of the Management Investors who are officers of FHP (the "FHP Management Investors") is terminated without cause, any Restrictions remaining applicable to the Management Stock owned by such FHP Management Investor shall terminate, and all unvested Management Stock owned by such FHP Management Investor shall vest. Such Restrictions shall be deemed to terminate, and such Management Stock shall be deemed to vest, prior to the time FHP's repurchase option provided for in Section 5.1, above, arises; PROVIDED, HOWEVER, that in such event, the Management Stock owned by such FHP Management Investor shall remain subject to the options provided by Sections 5.2 and 5.3, above, until the first to occur of the expiration of such options pursuant to the terms of Section 5, above, or the expiration of such options pursuant to the terms of Section 12.2, below. 12.2 CHANGE IN CONTROL OF THE COMPANY. Both the option granted under Section 5.1 and the Performance Purchase Option granted under Section 5.3 shall expire as to all Management Investors upon a Change in Control (as herein defined) of TMMC which occurs at any time after the date of the expiration of the subscription period during which the Rights are exercisable under the Rights Offering (the "Expiration Date"). For purposes of this Agreement, "Change in Control" means: (a) The acquisition by any individual entity or group (within the meaning of Section 13(d) or 14(d)(2) of the Exchange Act) (a "Person") of 2 beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of over 50% of either (i) the then outstanding shares of common stock of the Company (the "Outstanding Company Common Stock") or (ii) the combined voting power of the then outstanding voting securities of the Company entitled to vote generally in the election of directors (the "Outstanding Company Voting Securities"); PROVIDED, HOWEVER, that for purposes of this subsection (a), the following acquisitions shall not constitute a Change of Control: (i) any acquisition directly from the Company, (ii) any acquisition by FHP or PacifiCare, or (iii) any acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Company or PacifiCare, or any corporation controlled by the Company or PacifiCare; or (b) Individuals who, as of the Expiration Date, constitute the Board of Directors of the Company (the "Incumbent Board") cease for any reason to constitute at least a majority of the Board of Directors of the Company; PROVIDED, HOWEVER, that any individual becoming a director subsequent to the Expiration Date whose election, or nomination for election by the Company's shareholders, was approved by a vote of at least a majority of the directors then comprising the Incumbent Board shall be considered as though such individual were a member of the Incumbent Board, but excluding, for this purpose, any such individual whose initial assumption of office occurs as a result of an actual or threatened election contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies or consents by or on behalf of a Person other than the Board of Directors of the Company." 2. FHP PURCHASE OF STOCK. The parties hereto consent to the purchase by FHP from, and the issuance, sale and transfer to FHP by, (i) the Company of 87,500 shares of TMMC Common Stock, for consideration in the amount of $.01 per share, and (ii) THSC of 5 shares of THSC Common Stock, for consideration in the amount of $2.00 per share. Such purchases by FHP shall occur as soon as practicable after the execution of this Amendment, and pursuant to a resolution of the Board of Directors of each of the Company and THSC adopted as of September 17, 1996. 3. FHP CAPITALIZATION OF THE COMPANY. The parties hereto consent to any capital contributions which have been or will be made to the Company by FHP pursuant to Section 4.15(b) of the Reorganization Agreement. 4. GOVERNING LAW. This Amendment shall be governed by and construed in accordance with the law of the State of Delaware, without reference to its conflicts of law rules. 5. NO OTHER AMENDMENTS. The Stock Purchase Agreement, as amended by this Amendment, is and shall continue to be in full force and effect and is hereby in all respects ratified and confirmed. Except as provided herein, nothing in this Amendment shall waive or be deemed to waive or modify (except as expressly set forth herein) any rights or obligations of any of the parties under the Stock Purchase Agreement. 3 6. COUNTERPARTS. This Amendment may be executed in any number of counterparts, each of which will be deemed to be an original but all of which together will constitute but one instrument. IN WITNESS WHEREOF, the parties have duly executed this Amendment as of the date first above mentioned.

WHEREAS, concurrently with the FHP Merger, Holdings will distribute rights to purchase common stock of Holdings (the "Holdings Stock") to the common and preferred stockholders of FHP pursuant to a registration statement on Form S-1 (the "Offering").

EXCHANGE OF TMMC STOCK AND THSC STOCK FOR HOLDINGS STOCK.

Weinstock S-2 AMENDMENT NO. 4 TO STOCK PURCHASE AGREEMENT THIS AMENDMENT TO STOCK PURCHASE AGREEMENT ("Amendment") is made and entered into as of February 14, 1997 by FHP International Corporation, a Delaware corporation ("FHP"), as separate agreements between FHP and each of Westcott W. Price III, Kenneth S. Ord and Michael J. Weinstock (each an "Executive"), with reference to the following facts: A. Each Executive is a party to a separate Employment Agreement with FHP dated as of February 1, 1996 (each, as previously amended, such Executive's "Employment Agreement"). B. FHP, Talbert Medical Management Corporation and Talbert Health Services Corporation, each a Delaware corporation which is a wholly owned subsidiary of FHP (the "Company" and "THSC," respectively), the Executives, and certain other persons are parties to that certain Stock Purchase Agreement made and entered into as of March 15, 1996, as amended by Amendment No. 1 to Stock Purchase Agreement dated as of May 31, 1996, Amendment No. 2 to Stock Purchase Agreement dated as of September 17, 1996, and Amendment No. 3 to Stock Purchase Agreement dated as of February 14, 1997 (collectively, the "Talbert Stock Purchase Agreement"). C. FHP, N-T Holdings, Inc., a Delaware corporation ("PacifiCare Holding"), and certain other corporations are parties to that certain Amended and Restated Agreement and Plan of Reorganization dated as of November 11, 1996 (the "Reorganization Agreement"), pursuant to Section 4.15 of which PacifiCare Holding is required to cause the issuance of rights to shareholders of FHP to purchase, directly or indirectly through one or more other corporations formed to facilitate such purchase, all of FHP's interest in TMMC and THSC. In accordance with Section 4.15, the issuance of such rights to purchase stock of Talbert Medical Management Holdings Corporation, a Delaware corporation formed to acquire FHP's interest in TMMC and THSC ("TMMHC"), has been registered under the Securities Act of 1933 (the "Talbert Rights Offering"). TMMC and THSC collectively, and TMMHC if it acquires TMMC and THSC in connection with the Talbert Rights Offering, are referred to herein as "Talbert," and stock of TMMC and THSC, or of TMMHC if the Executives acquire stock of TMMHC pursuant to the Talbert Stock Purchase Agreement, is referred to herein as "Talbert Stock." -1- D. FHP and the Executives deem it to be in their mutual best interests to amend the Talbert Stock Purchase Agreement to delete certain restrictions imposed thereby upon stock of Talbert owned by the Executives, provided the Talbert Rights Offering results in the issuance of Talbert Stock to the public. NOW, THEREFORE, the parties agree as follows: 1. DELETION OF PERFORMANCE PURCHASE OPTIONS. Subject to and upon the expiration of seven (7) days following the closing of an issuance of Talbert Stock upon the exercise of rights issued in the Talbert Rights Offering (such closing the "Talbert IPO Closing"), the Talbert Stock Purchase Agreement with respect to each Executive shall be and hereby is amended by deleting the provisions of Section 5.3 thereof (relating to the "Performance Purchase Options" as therein defined). 2. UPDATING OF PARACHUTE PAYMENT CALCULATIONS. FHP shall cause Deloitte & Touche LLP, as the "Accounting Firm" (as defined in Section 11(b) of the Employment Agreement of each Executive), to make calculations for each Executive, as of the date of the Talbert IPO Closing and assuming effectiveness of the amendment of the Talbert Stock Purchase Agreement pursuant to Section 1 of this Amendment (such calculations as to an Executive, a "Parachute Recalculation"), as to (i) whether a Payment (as defined in Section 11 of his Employment Agreement) or benefit paid or required to be paid to him by FHP is or would be an excess parachute payment within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (an "Excess Parachute Payment"), and (ii) the amount of Talbert Stock (such amount, a "Parachute Adjustment"), if any, that such Executive would have to forfeit pursuant to Section 2(b) below in order to avoid treatment of any such Payment or benefit as an Excess Parachute Payment. With respect to each Executive, the Parachute Recalculation shall be deemed to be determinations required to be made under Section 11 of his Employment Agreement. a. NO EXCESS PARACHUTE PAYMENT. If the Parachute Recalculation for an Executive indicates that no Excess Parachute Payment is or has been required to be made by FHP to Executive, then the amendment pursuant to Section 1 of this Amendment shall be deemed to be fully effective. b. EXCESS PARACHUTE PAYMENT. If, but for the provision of this Section 2(b), the Parachute Recalculation for an Executive indicates that a Parachute Adjustment is required in order to avoid treatment of a Payment or benefit referred to above as an Excess Parachute Payment to such Executive, then, (i) effective upon the expiration of seven (7) days following the Talbert IPO Closing, such Executive shall -2- be deemed to have forfeited to FHP that number of his shares of Talbert Stock corresponding to the Parachute Adjustment for such Executive (and Executive shall promptly surrender the certificate or certificates for such number of shares to FHP), and (ii) the amendment pursuant to Section 1 hereof shall be deemed to be fully effective as to the balance of shares of Talbert Stock owned by such Executive. 3. LIMITATION IN THE EVENT OF EXCESS PARACHUTE PAYMENTS. All amounts payable to the Executives for services are intended to be reasonable compensation therefor. Notwithstanding the foregoing, should the Internal Revenue Service determine, or the applicable court if such Internal Revenue Service determination is disputed, that payment to Executive of any amount payable under his Employment Agreement, together with any other amounts that must be included in such determination, will result in the payment to him of an Excess Parachute Payment, then such Executive shall repay to the Company, the minimum amount ("Overpayment") that would have to be repaid such that the Parachute Adjustment with respect to that Executive would be zero. Any forfeiture by such Executive of Talbert Stock pursuant to Section 2(b) hereof shall be treated as such a repayment on the date of forfeiture to the extent of the fair market value of such Talbert Stock as of such date. Any Overpayment shall be treated for all purposes as a loan by FHP to Executive from the date such Overpayment was made in an amount equal to the value of such Overpayment as of such date, which loan Executive shall repay to FHP, together with interest at the applicable federal rate under Section 7872(f)(2)(B) of the Internal Revenue Code of 1986, as amended, within thirty (30) business days after receipt by -3- Executive of a final determination by the Internal Revenue Service, or appropriate court as the case may be. 4. GOVERNING LAW. This Amendment shall be governed by and construed in accordance with the law of the State of Delaware, without reference to its conflicts of law rules. 5. NO OTHER AMENDMENTS. The Talbert Stock Purchase Agreement, as amended by this Amendment, is and shall continue to be in full force and effect and is hereby in all respects ratified and confirmed. Except as provided herein, nothing in this Amendment shall waive or modify or be deemed to waive or modify (except as expressly set forth herein) any rights or obligations of any of the parties under the Talbert Stock Purchase Agreement. 6. COUNTERPARTS. This Amendment may be executed in any number of counterparts, each of which shall be deemed to be an original but all of which together shall constitute but one instrument.
