Item 3. Source and Amount of Funds or Other Consideration. Pursuant to the Merger Agreement described in Item 4 below, at the Effective Time (as defined in Item 4 below) HLR received 49,008,538 shares of Common Stock and (in accordance with an agency agreement with HLR) Holdings received 12,320,718 shares of Common Stock. The total of 61,329,256 shares of Common Stock acquired by the Reporting Persons collectively (the "Roche Shares") represents, in the aggregate, approximately 49.9% of the outstanding Common Stock, based upon the Company's estimate of the number of outstanding shares as of April 28, 1995, immediately after the Merger (as described in Item 4 below). The Roche Shares were issued pursuant to the Merger Agreement through (i) a conversion of all of the outstanding shares of common stock, no par value per share, of Roche Biomedical Laboratories, Inc. ("RBL"), a New Jersey corporation which, prior to the Merger, was a wholly-owned subsidiary of HLR, into Common Stock at the Effective Time and (ii) the payment by HLR (with funds provided by Holdings pursuant to an agency agreement as referred to below) of an aggregate of $135,651,100 (the "HLR Cash Consideration"). The HLR Cash Consideration was financed from working capital of Holdings (including funds from general purpose financing obtained by Holdings) and paid by HLR on behalf of Holdings pursuant to an agency agreement dated as of April 27, 1995. In addition, pursuant to the Merger Agreement, on April 28, 1995, the effective date of the Merger (the "Effective Date") Roche purchased from the Company, for an aggregate purchase price of $51,048,900 (the "Roche Warrant Consideration"), 8,325,000 warrants to purchase shares of Common Stock (the "Roche Warrants"). The principal terms of such Roche Warrants are set forth in the Warrant Agreement described in Item 4 below. The Roche Warrant Consideration was financed from working capital of Roche (including funds provided from general purpose financing obtained by Roche). Item 4. Purpose of Transaction. The acquisition of the Common Stock, including the Roche Shares, and the Roche Warrants referred to in Item 3 above was made pursuant to an Agreement and Plan of Merger dated as of December 13, 1994 among the Company, HLR, RBL and (for the purposes stated therein) Roche (the "Merger Agreement"). The Merger Agreement provided that, following the approval and adoption of the Merger Agreement by the stockholders of the Company and the satisfaction or waiver of the other conditions to the Merger (i) RBL would be merged with and into the Company (with the Company being the surviving corporation) (the "Merger"), (ii) each outstanding share of Common Stock (other than shares of Common Stock owned by RBL or HLR and other than certain shares of Common Stock owned by stockholders who properly exercise their appraisal rights under Delaware law) would be converted into (A) 0.72 of a share of Common stock and (B) the right to receive $5.60 in cash, without interest (the "Cash Consideration"), and (iii) all shares of common stock, no par value, of RBL outstanding immediately prior to the Effective Time (other than treasury shares, which would be cancelled) would be converted into, and become, that number of newly issued shares of Common Stock as would, in the aggregate and after giving effect to the Merger and the Common Stock owned by HLR and RBL and their subsidiaries immediately prior to the Effective Time, equal 49.9% of the total number of shares of Common Stock outstanding immediately after the Effective Time (after giving effect to the issuance of Common Stock in respect of certain Company employee stock options in connection with the Merger, as described in the Merger Agreement). A copy of the Merger Agreement is attached as Exhibit 1 hereto and is hereby incorporated herein by reference, and the description herein of the terms of such agreement is qualified in its entirety by reference to such Exhibit. On April 28, 1995, at a special meeting of stockholders of the Company, the Company's stockholders voted to approve and adopt the Merger Agreement and to amend the Company's certificate of incorporation to change the name of the Company from National Health Laboratories Holdings Inc. to Laboratory Corporation of America Holdings. Later on the Effective Date, a certificate of merger was filed with each of the Secretary of State of the State of Delaware and the Secretary of the State of the State of New Jersey, and the Merger was consummated (the "Effective Time"), and the Roche Shares and the Roche Warrants were issued to the Reporting Persons as referred to in Item 3 above. In connection with the Merger, the Company declared a dividend, payable to holders of record of shares of the Company Common Stock as of April 21, 1995, which dividend consisted of 0.16308 of a warrant per outstanding share of Common Stock, each such warrant (a "Warrant" and, together with the Roche Warrants, the "Warrants") representing the right to purchase one newly issued share of Common Stock for $22.00 (subject to adjustments as provided in the Warrant Agreement) on April 28, 2000 (the "Expiration Date"). In addition, pursuant to the Merger Agreement, on April 28, 1995 Roche purchased and was issued the Roche Warrants for the Roche Warrant Consideration. The terms of the Warrants (including the Roche Warrants) are set forth in the Warrant Agreement (the "Warrant Agreement") dated as of April 10, 1995, between the Company and American Stock Transfer & Trust Company (the "Warrant Agent"). Pursuant to the Warrant Agreement, the Company has the right, exercisable by notice at least 60 but not more than 90 days prior to the Expiration Date, to redeem the Warrants on the Expiration Date for a cash redemption price per Warrant equal to the average closing price of the shares of the Common Stock over a specified period prior to the Expiration Date minus the exercise price of $22.00 per share (subject to adjustments). A copy of the Warrant Agreement is attached as Exhibit 2 hereto and is hereby incorporated herein by reference, and the description herein of the terms of such agreement is qualified in its entirety by reference to such Exhibit. In connection with the Merger, the Company, HLR, Roche and Holdings entered into a stockholder agreement dated as of April 28, 1995 (the "Stockholder Agreement") which sets forth, among other things, certain agreements and understandings regarding the governance of the Company following the Merger, including but not limited to the composition of the Board of Directors. The Stockholder Agreement also contains certain provisions relating to the issuance, sale and transfer of the Company's Equity Securities (as defined in the Stockholder Agreement) by the Company, HLR and Holdings (for the purposes of the Stockholder Agreement, HLR and Holdings are collectively referred to herein as the "Investor"), the acquisition of additional Equity Securities of the Company by the Investor and the registration rights granted by the Company to the Investor and its affiliates (other than the Company and its subsidiaries) (the "Investor Group") with respect to the Company's Equity Securities, which provisions are described under Item 6 below and which description is incorporated herein by reference. A copy of the Stockholder Agreement is attached as Exhibit 3 hereto and is hereby incorporated herein by reference, and the description herein of the terms of such agreement is qualified in its entirety by reference to such Exhibit. Pursuant to the Stockholder Agreement (subject to the exceptions provided therein), for a period of one year after the Effective Date (the "Initial Period") the Board of Directors of the Company will be comprised of seven members, consisting of James R. Maher, three designees of the Investor (each an "Investor Director"), who are Jean-Luc Belingard (the Director General, Diagnostics Division and Executive Committee Member of F. Hoffmann-La Roche Ltd), Thomas P. Mac Mahon (a Senior Vice President of Roche and the President of Roche Diagnostics Group) and Dr. James B. Powell (former President of RBL who is the President and Chief Executive Officer of the Company), and three Independent Directors (as defined in the Stockholder Agreement, which provides in general that such persons shall not be officers, employees or affiliates of the Company or the Investor). The Stockholder Agreement provides that these Independent Directors were required to be mutually acceptable to a majority of the members of the Company's Board of Directors in office immediately prior to the Effective Time and to the Investor. Following the Initial Period, the Board of Directors of the Company will (subject to specified exceptions described in the Stockholder Agreement) be comprised of seven members, consisting of three Investor Directors and four Independent Directors selected by the Nominating Committee of the Board of Directors. Consistent with the Stockholder Agreement, Mr. Maher has been elected by the Board of Directors to serve as the Chairman of the Board of the Company and Mr. Mac Mahon has been elected to serve as the Vice Chairman of the Board of the Company for the Initial Period. The Stockholder Agreement provides that, if the percentage (the "Investor Group Interest") of the aggregate number of votes entitled to be voted in an election of directors of the Company by all outstanding securities having the right to vote generally in any election of Directors of the Company ("Total Voting Power") that is controlled directly or indirectly by the Investor Group is less than 30% but at least 20%, the Investor will have the right to designate for nomination two Investor Directors, and if the Investor Group Interest is less than 20% but at least 10%, the Investor will have the right to designate for nomination one Investor Director. The Stockholder Agreement provides that the Board of Directors of the Company will establish, empower, maintain and elect the members of the following committees of the Board of Directors: (i) an Audit Committee, comprised solely of Independent Directors, (ii) a Nominating Committee, which will be comprised of one Investor Director (designated by the majority of Investor Directors), and two Independent Directors (designated by the majority of Independent Directors), (iii) an Employee Benefits Committee, comprised of Investor Directors and Independent Directors (with the Independent Directors constituting a majority) and (iv) such other committees as the Board of Directors deems necessary or desirable to establish, empower and maintain, provided that such committees are approved by a majority of the Board of Directors, which majority includes approval by a majority of the Investor Directors and at least one Independent Director (a "Special Majority of the Board"). Except as otherwise provided in the Stockholder Agreement or as agreed by a majority of the Independent Directors and the Investor Directors, the number of Investor Directors serving on each committee of the Board of Directors will be the same proportion of the total membership of such committee as the number of Investor Directors is of the entire Board of Directors, with a minimum of one member so long as the Investor is entitled under the Stockholder Agreement to designate one Investor Director. Notwithstanding the previous sentence, if the Investor Group Interest is less than 30% but more than 20%, the number of Investor Directors serving on each committee of the Board of Directors (other than the Audit Committee) will be two, if such committee has five or more total members, or one, in all other cases. If the Investor Group interest is less than 20% but more than 10%, the number of Investor Directors serving on each committee of the Board of Directors (other than the Audit Committee) will be one. The Stockholder Agreement provides that, so long as the Investor Group Interest is 30% or more, no action by the Company or any of its subsidiaries will be taken with respect to any of the following matters without the approval of a Special Majority of the Board: (i) the appointment of any of the Chairman of the Board, Chief Executive Officer, President, Secretary, Treasurer, Chief Administration Officer, General Counsel, Chief Financial Officer or Chief Operating Officer or other executive officer in any similar capacity of the Company or any of its subsidiaries, (ii) the approval of Strategic Plans and Annual Operating Plans (referred to below), (iii) any merger or consolidation of the Company or any of its subsidiaries with or into any Person (as defined in the Stockholder Agreement) other than the Company or any of its subsidiaries, (iv) any amendment to the certificate of incorporation or the bylaws of the Company or any adoption of, or amendment to, the certificate of incorporation or the bylaws of any subsidiary of the Company, (v) any acquisition of assets, business, operations or securities by the Company or any of its subsidiaries by merger or otherwise

authority or where the amount to be paid in settlement is in excess of $5,000,000, (viii) any material transaction between the Company or any of its subsidiaries, on the one hand, and any stockholder

(B) seeking appointment of a receiver, trustee, custodian or other similar official for the Company or any of its subsidiaries or for all or any Substantial Part of the Company or any of its subsidiaries or making a general assignment for the benefit of the creditors of the Company or any of its subsidiaries. The Stockholder Agreement also requires that the Annual Operating Plans and the Strategic Plans (each as defined in the Stockholder Agreement) be approved by a Special Majority of the Board of Directors. The purpose of HLR, Roche and Holdings in effecting the Merger and acquiring the Roche Shares was to acquire a substantial equity interest in the Company and the benefits of the Stockholder Agreement and the Sharing and Call Option Agreement (referred to in Item 6 below). The Reporting Persons intend to review continually the Company's business affairs and financial condition, as well as conditions in the securities markets and general economic and industry conditions. Based on an evaluation of these and other similar considerations and as consistent with the Stockholder Agreement, the Reporting Persons will continue to consider various alternative courses of action and will in the future take such actions with respect to the Company as each of them deems appropriate in light of the circumstances existing from time to time. Except as set forth herein, none of the Reporting Persons nor any other person controlling the Reporting Persons, nor, to the best of the knowledge of any of the Reporting Persons, any person named in Schedules A, B, C, D and E attached hereto currently has any plans or proposals which relate to or would result in (i) the acquisition by any person of additional securities of the Company, or the disposition of securities of the Company; (ii) an extraordinary corporate transaction, such as a merger, reorganization or liquidation involving the Company or any of its subsidiaries; (iii) a sale or transfer of a material amount of assets of the Company or any of its subsidiaries; (iv) any change in the present Board of Directors or management of the Company; (v) any material change in the present capitalization or dividend policy of the Company; (vi) any other material change in the Company's business or corporate structure; (vii) changes in the Company's charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Company by any person; (viii) causing the Common Stock to cease to be authorized to be quoted on the New York Stock Exchange; (ix) the Common Stock becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Exchange Act; or (x) any action similar to any of those enumerated in this paragraph.

In the Merger, HLR acquired 49,008,538 shares of Common Stock and Holdings acquired 12,320,718 shares of Common Stock. Based upon information provided by the Company, the Reporting Persons believe that the Roche Shares represent approximately 49.9% of the Common Stock estimated to be outstanding after the Effective Time on the Effective Date. The Roche Shares owned by HLR may be deemed, for purposes of Rule 13d-3, to be beneficially owned by Roche, Holdings, Finance, Roche Holding and Dr. Sacher.

The Roche Warrants are not exercisable until April 28, 2000, and the Reporting Persons disclaim beneficial ownership of the shares of Common Stock issuable upon exercise of the Roche Warrants. To the best of the knowledge of the Reporting Persons, the number of shares of Common Stock beneficially owned by the persons named in Schedules A, B, C, D and E hereto (beneficial ownership of which shares is disclaimed by the Reporting Persons) is set forth below: No. of Shares of Common Stock Individual Beneficially Owned __________ _____________________________ Patrick J.

(d) Inapplicable. (e) Inapplicable. Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer. The information contained in Item 4 above is hereby incorporated by reference herein. In addition to the provisions of the Stockholder Agreement described above in Item 4, the Stockholder Agreement prohibits, subject to certain exceptions, the Company from issuing, selling or transferring any (i) Common Stock or other voting stock of the Company, (ii) any debt or equity securities of the Company convertible or exchangeable for Common Stock or voting stock of the Company or (iii) any options, rights or warrants issued by the Company to acquire Common Stock or other voting stock of the Company ("Equity Securities") to any person, unless the Investor is offered in writing the right to purchase, at the same price and on the same terms proposed to be issued or sold, an amount of such Equity Securities (the "Maintenance Securities") as is necessary for the Investor Group to maintain the Investor Group Interest as it existed immediately prior to such issuance (the "Anti-Dilutive Rights"). If the Investor does not deliver to the Company written notice of acceptance of any such offer within 20 business days after the Investor's receipt thereof, the Investor will be deemed to have waived its right to purchase all or part of the Maintenance Securities as set forth in such offer, but the Investor will retain its Anti-Dilutive Rights with respect to future offers. The Anti-Dilutive Rights do not apply to (i) the grant or exercise of options to purchase shares of stock of the Company, the issuance of shares of stock of the Company to employees of the Company or any of its subsidiaries (other than employees who are also employees of a stockholder, its affiliates or any subsidiary of a stockholder) or otherwise pursuant to any stock option or similar plan in existence on the date of the Stockholder Agreement or otherwise adopted by the Board of Directors after the date of the Stockholder Agreement, (ii) the issuance of the stock of the Company pursuant to the Warrants or of shares of the stock of the Company issuable upon exercise of any option, warrant, convertible security or other rights to purchase shares of stock of the Company which, in each case, has been issued in compliance with the terms of the provisions pertaining to the Anti-Dilutive Rights, (iii) the issuance of any securities pursuant to any stock split, stock dividend or other similar stock recapitalization or (iv) the issuance of shares of stock of the Company pursuant to any underwritten public offering of Equity Securities under an effective registration statement filed by the Company with the Securities and Exchange Commission (the "SEC") in accordance with the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (the "Securities Act") (such an offering being referred to as a "Public Offering"), provided that the action described in clauses (i), (iii) or (iv) above, as the case may be, has been approved (to the extent required) in accordance with the provisions of the Stockholder Agreement. The Stockholder Agreement provides that, during the Initial Period, the Investor may not, and will use its best efforts to cause each member of the Investor Group not to, directly or indirectly, purchase or otherwise acquire any Equity Securities if, after giving effect thereto, the Investor Group Interest would exceed 49.99%. Notwithstanding the foregoing, the Stockholder Agreement permits the Investor Group or one or more members thereof to acquire, directly or indirectly, by purchase or otherwise, Equity Securities resulting in the Investor Group Interest exceeding such limitation in the event (i) any Person or group makes an Acquisition Proposal (as defined in the Merger Agreement), (ii) after the Effective time, Mafco Holdings Inc., a Delaware Corporation ("Mafco"), or any affiliate thereof acquires Equity Securities representing 1% or more of the Total Voting Power, (iii) any Person or group acquires beneficial ownership of Equity Securities representing 5% or more of Total Voting Power (10% or more in the case of beneficial ownership permitted to be reported on Schedule 13G under the Exchange Act), or (iv) there has been a material adverse change in the business, financial condition or operations of the Company for, or which would reasonably be expected to continue for, a sustained period, and the Investor has determined in good faith that the acquisition of additional Equity Securities is reasonably necessary to protect its investment in the Company. The Stockholder Agreement requires that from the first anniversary of the Effective Date until the third anniversary of the Effective Time the Investor not, and use its best efforts to cause each member of the Investor Group not to, directly or indirectly, purchase or otherwise acquire, or propose or offer to purchase or acquire, any Equity Securities of the Company, whether by tender offer, market purchase, privately negotiated purchase, merger or otherwise, except that the Investor Group may acquire Equity Securities to the extent that, after giving effect thereto, the Investor Group Interest would not exceed 75%. The Stockholder Agreement permits, however, the Investor Group to acquire Equity Securities, notwithstanding the fact that, after giving effect thereto, the Investor Group Interest would exceed 75%, if the Investor Group (or a member or affiliate thereof, as the case may be) offers, prior to consummating such purchase, to purchase all outstanding Equity Securities, and holders of Equity Securities representing more that 50% of the outstanding Equity Securities (excluding any Equity Securities held by the Investor Group) accept such offer, and the Investor Group (or a member or affiliate thereof, as the case may be) consummates such purchase. The Stockholder Agreement provides that the Investor may not sell or otherwise transfer any Equity Securities, except pursuant to a Public Offering, Rule 144 or Rule 144A or any other transaction in compliance with the Securities Act, state securities laws and other applicable laws. The Investor has agreed to cause any Person who acquires 30% of the Total Voting Power from the Investor to agree to be bound by the provisions of the Stockholder Agreement, whereupon such Person will become entitled to all of the rights and benefits of HLR under the Stockholder Agreement. The Stockholder Agreement provides that the Investor (which, for the purposes of this paragraph and the following three paragraphs hereof, includes Roche) may from time to time make a written request to the Company for registration under the Securities Act of Registrable Securities (as defined in the Stockholder Agreement) (each, a "Demand Registration"). The obligations of the Company to register such Registrable Securities are subject to the following conditions: (i) the Registrable Securities requested to be registered must (unless reduced pursuant to the provisions of the section of the Stockholder Agreement entitled "Reduction of Offering"), constitute at least 2% of the equivalent outstanding Equity Securities or at least 5% of the Registrable Securities at such time, whichever amount is smaller, (ii) there shall not have been consummated more than one offering pursuant to a Demand Registration within the preceding 12 month period, (iii) if the Investor Group Interest is less than 30% but more than 20%, no more than three other Demand Registrations shall have been effected after the date on which the Investor Group Interest was reduced to less than 30%, if the Investor Group Interest is less than 20% but more than 10%, no more than two other Demand Registrations shall have been effected after the date on which the Investor Group Interest was reduced to less than 20% and if the Investor Group Interest is less than 10%, no more than one other Demand Registration shall have been effected after the date on which the Investor Group Interest was reduced to less than 10%, (iv) the Investor shall conform to all applicable requirements of the Securities Act and the Exchange Act with respect to the offering and sale of securities and advise each underwriter, broker or dealer through which any of the Registrable Securities are offered that the Registrable Securities are part of a distribution that is subject to the prospectus delivery requirements of the Securities Act and (v) the Investor shall use all reasonable efforts to effect as wide a distribution of such Registrable Securities as is reasonably practicable, but in no event will any sale of Registrable Securities be made knowingly to any Person who beneficially owns 5% or more of the Total Voting Power. In addition, the Company's obligations pursuant to any Demand Registration will be suspended if (i) the fulfillment of such obligations would require the Company to make a disclosure that would, in the reasonable good faith and judgment of the Board of Directors, be materially detrimental and premature, (ii) the Company has filed a registration statement with respect to Equity Securities to be distributed in a Public Offering and it is advised by its lead or managing underwriter that an offering by the Investor of the Registrable Securities would materially adversely affect the distribution of such Equity Securities or (iii) the fulfillment of such obligations would require the Company to prepare audited financial statements not required to be prepared for the Company to comply with its obligations under the Exchange Act as of any date not coincident with the last day of any fiscal year of the Company. The obligations of the Company, however, will be reinstated (x) in the case of clause (i) above, upon the making of such disclosure (or, if earlier, when such disclosure would either be no longer necessary for the fulfillment of such obligations or no longer detrimental), (y) in the case of clause (ii) above, upon the conclusion of any period during which the Company would not, pursuant to the terms of its underwriting arrangements, be permitted to sell securities of the Company for its own account and (z) in the case of clause (iii) above, as soon as it would no longer be necessary to prepare such financial statements to comply with the Exchange Act. The Stockholder Agreement provides that, if the Company proposes to file a registration statement under the Securities Act with respect to an offering of any securities of the Company for the Company's own account (other than a registration statement on Form S-4 or S-8 (or any substitute that may be adopted by the SEC) or the account of any holder of Equity Securities other than any member of the Investor Group (each, an "Other Holder") (other than Mafco or any of its affiliates), then the Company will give written notice of such proposed filing to the Investor as soon as practicable, and such notice will offer the Investor the opportunity to register such number of shares of, or Warrants constituting, Registrable Securities as the Investor may request on the same terms and conditions as those applicable to the securities of the Company or of the Other Holders in the offering (a "Piggyback Registration"). Upon the written request of the Investor made within ten days after the receipt of notice from the Company, which request shall specify the amount and types of Registrable Securities intended to be issued or disposed of, the Company will use its best efforts, subject to certain conditions set forth in the Stockholder Agreement, to effect the registration under the Securities Act of all such Registrable Securities which the Company has been so requested to register by the Investor, to the extent requisite to permit the disposition of such Registrable Securities to be so registered. In connection with any Demand Registration or any Piggyback Registration, the Company will pay all Registration Expenses (as defined in the Stockholder Agreement) of the Investor. Pursuant to the Stockholder Agreement, the Company has agreed that it will file necessary reports with the SEC and to take other action as reasonably requested by the Investor to enable it to sell its Company securities pursuant to Rule 144 under the Securities Act. If the Investor desires to transfer any of its securities of the Company pursuant to Rule 144A, the Stockholder Agreement requires the Company to promptly, upon request by the Investor, use its best efforts to facilitate the consummation of such Rule 144A transaction in accordance with the requirements of such rule and with such request and will take all necessary or appropriate actions in connection therewith. If the Investor Group Interest is less than 30%, then the Company will only be required to facilitate the consummation of such Rule 144A transaction according to the following provisions: (i) if the Investor Group Interest is less than 30% but more than 20%, no more than three other Rule 144A transactions will have been effected after the date on which the Investor Group Interest was reduced to less than 30%, (ii) if the Investor Group Interest is less than 20% but more that 10%, no more than two other Rule 144A transaction will have been effected after the date on which the Investor Group Interest was reduced to less than 20% and (iii) if the Investor Group Interest is less than 10%, no more than one other Ruler 144A transaction will have been effected after the date on which the Investor Group Interest was reduced to less than 10% the Company has agreed to pay all expenses in connection with Rule 144A transactions by the Investor to the same extent as the Company would be required to pay Registration Expenses. In the Stockholder Agreement, the Company has agreed to provide certain information to the Investor on a periodic basis and as requested, and the Company has agreed that it will not enter into any agreements with respect to its securities which would be inconsistent with the rights granted to the Investor, the Investor Group and the Investor Directors in the Stockholder Agreement. The provisions of the Stockholder Agreement will terminate if the Investor Group Interest is less than 30%, provided, however, that the provisions relating to the obligation of the Company to furnish certain information will not terminate until such time as the Investor Group Interest is less than 20%, certain provisions regarding Board and Board committee membership and amendment of the Company's certificate of incorporation and bylaws will not terminate until such time as the Investor Group Interest is less than 10%, the registration rights will not terminate until such time as the Investor Group does not own any Registrable Securities (except the provisions relating to Piggyback Registrations, which will terminate at such time as the Investor Group Interest is less than 20%) and certain miscellaneous provisions will not terminate until all other provisions of the Stockholder Agreement have terminated. Furthermore, in the event that the Investor Group Interest exceeds 50%, the provisions pertaining to corporate governance will terminate, but will be reinstated, at the request of the Investor, if the Investor Group Interest is later reduced below 50%. The description herein regarding terms of Stockholder Agreement is qualified by reference to Exhibit I attached hereto and incorporated by reference herein. In connection with entering into the Merger Agreement, HLR, Mafco, National Health Care Group, Inc., a Delaware corporation ("NHCG"), and (for the purposes set forth therein) the Company entered into the Sharing and Call Option Agreement dated as of December 13, 1994 (the "Sharing and Call Option Agreement"), which among other things, sets forth certain agreements among the parties thereto with respect to the securities of the Company, as described below. A copy of the Sharing and Call Option Agreement is filed as Exhibit 4 hereto and is hereby incorporated herein by reference, and the description herein of the terms of such agreement is qualified in its entirety by reference to such Exhibit. The Sharing and Call Option Agreement provides (among other things) that at any time after the third anniversary of the Effective Date, a member of the Investor Group may exercise the right (the "Call Right"), which right may only be exercised once, to purchase all, but not less than all, the shares of Common Stock then owned by NHCG, Mafco or any of their controlled affiliates. If a member of the Investor Group intends to exercise the Call Right, then, not less than 20 business days prior to the exercise thereof, such member is required to so notify Mafco and NHCG of such intention, specifying in such notice (the "Call Notice") the date of such exercise (the "Exercise Date"). From and after the receipt of a Call Notice, the Sharing and Call Option Agreement prohibits NHCG, Mafco and any of their controlled affiliates from transferring any shares of Common Stock that are owned by them except during any period expiring 15 business days prior to the Exercise Date. The Sharing and Call Option Agreement provides that a member of the Investor Group will pay a price per share for the shares to be purchased equal to 102% of the average closing price per share of such security as reported on the principal national securities exchange on which such shares are listed, or if not so listed, as reported on NASDAQ/NMS, for the 30 trading days before the Exercise Date. Except as otherwise described herein, to the best of the Reporting Persons' knowledge, there are no contracts, arrangements, understandings or relationship (legal or otherwise) among the Reporting Persons and between the Reporting Persons and any person with respect to any securities of the issuer, including but not limited to transfer or voting of any of the securities, finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.

WHEREAS, the respective Boards of Directors of HLR, RBL and NHL have approved the merger of RBL with and into NHL (the "Merger") upon the terms and subject to the conditions of this Agreement and in accordance with the General Corporation Law of the State of Delaware ("Delaware Law"); and WHEREAS, the Board of Directors of NHL has determined that the Merger is fair to, and in the best interests of, the holders of NHL common stock, par value $0.01 per share ("NHL Common Stock"), and has approved this Agreement, the Sharing and Call Option Agreement dated the date hereof among HLR, National Health Care Group, Inc. ("NHCG"), a Delaware corporation, which is a significant stockholder of NHL, and Mafco Holdings Inc., the ultimate parent company of NHCG (the "Sharing and Call Option Agreement") and the HLR Stockholder Agreement to be entered into immediately prior to the Merger by HLR and NHL which agreement shall be substantially in the form of Exhibit A hereto (the "HLR Stockholder Agreement") and the transactions contemplated hereby and thereby, and recommended approval and adoption of this Agreement and such transactions by the stockholders of NHL; and WHEREAS, the Board of Directors of RBL has determined that the Merger is fair to, and in the best interests of, RBL and HLR, and has approved this Agreement, and the transactions contemplated hereby and the Board of Directors of HLR has approved and adopted this Agreement and has approved the HLR Stockholder Agreement and the Sharing and Call Option Agreement and the transactions contemplated hereby and thereby; and WHEREAS, the parties intend that the Merger qualify as a reorganization within the meaning of Section 368(a)(i) of the Internal Revenue Code of 1986, as amended (the "Code"); and WHEREAS, in connection with the Merger, a portion of each share of NHL Common Stock will be converted into the right to receive $5.60 in cash in a transaction constituting a redemption within the meaning of Section 317(b) of the Code; and NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements contained herein, the parties hereto agree as follows: ARTICLE 1 THE MERGER SECTION 1.1. The Merger. (a) Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with Delaware Law, RBL shall be merged with and into NHL at the Effective Time (as defined in Section 1.1(b)), whereupon the separate existence of RBL shall cease, and NHL shall be the surviving corporation (the "Surviving Corporation"). (b) As soon as practicable after satisfaction or, to the extent permitted hereunder, waiver of all conditions to the Merger, NHL and RBL will file a certificate of merger, in the form required by and executed in accordance with Delaware Law, with the Secretary of State of the State of Delaware and make all other filings or recordings required by Delaware Law in connection with the Merger. The Merger shall become effective at such time as the certificate of merger is duly filed with the Secretary of State of the State of Delaware, which shall be as soon as practicable following the NHL Stockholder Meeting (as defined in Section 5.2 hereof) (the "Effective Time"). (c) From and after the Effective Time, the Surviving Corporation shall possess all the rights, privileges, powers and franchises and be subject to all of the restrictions, disabilities and duties of NHL and RBL, all as provided under Delaware Law. SECTION 1.2. Conversion of Shares. At the Effective Time: (a) each share of NHL Common Stock (each an "NHL Share") issued and outstanding prior to the Effective Time (other than any NHL Shares held by RBL, HLR or any Subsidiary) (as defined in Section 3.1) shall, subject to Section 1.2(d) be converted into (x) 0.72 of an NHL Share and (y) the right to receive $5.60 in cash without interest thereon (the "Cash Consideration" and, together with the NHL Shares to be issued pursuant to (x) above, the "Conversion Consideration"; such conversion is referred to herein as the "NHL Share Conversion"); (b) all RBL common shares, no par value (each a "Share" and collectively the "Shares"), outstanding immediately prior to the Effective Time shall (except as provided in Section 1.2(c)) be converted into and become, in the aggregate, the HLR Number (as defined below) of NHL Shares, newly issued as contemplated by this Agreement (the "HLR-NHL Shares"), each such HLR-NHL Share having the same rights, powers and privileges as an NHL Share outstanding immediately prior to the Effective Time. The "HLR Number" shall be that number of NHL Shares as would, in the aggregate and after giving effect to the Merger (including issuance of the HLR-NHL Shares and the NHL Share Conversion) and the number of NHL Shares held by HLR or any Affiliate immediately prior to the Merger, equal 49.9% of the total number of NHL Shares which would be outstanding immediately after the Effective Time (after giving effect to the issuance under such Section 1.5 of NHL Shares in respect of Employee Stock Options (as defined in Section 1.5(a)). If between the date of this Agreement and the Effective Time, the outstanding shares of NHL Common Stock shall have been changed into a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares, the HLR Number shall be correspondingly adjusted to reflect such stock dividend, subdivision, classification, recapitalization, split, combination or exchange of shares (any such adjustment being referred to herein as an "Anti-dilution Adjustment"); and (c) each Share held by RBL, HLR or any Subsidiary thereof as treasury stock immediately prior to the Effective Time shall be canceled and no payment or issuance of a HLR-NHL Share shall be made with respect thereto; (d) no certificates or scrip representing less than one share of NHL Common Stock shall be issued upon the surrender for exchange of Certificates pursuant to Section 1.2. In lieu of any such fractional share, each holder of a Certificate who would otherwise have been entitled to a fraction of a share of NHL Common Stock upon surrender of Certificates for exchange pursuant to Section 1.2 shall be paid upon such surrender cash (without interest) in an amount equal to such holder's proportionate interest in the net proceeds from the sale or sales in the open market by the Exchange Agent, (as defined in Section 1.3) on behalf of all such holders, of the aggregate fractional NHL Common Stock issued pursuant to this Section 1.2(d). As soon as practicable following the Effective Time, the Exchange Agent shall determine the excess of (i) the number of full shares of NHL Common Stock delivered to the Exchange Agent by NHL over (ii) the sum of the number of full shares of NHL Common Stock to be distributed to each holder of Certificates (such excess being herein called the "Excess Shares"), and the Exchange Agent, as agent for the former holders of Certificates, shall sell the Excess Shares at the prevailing prices on the New York Stock Exchange, Inc. ("NYSE"). The sales of the Excess Shares by the Exchange Agent shall be executed on the NYSE through one or more member firms of the NYSE and shall be executed in round lots to the extent practicable. NHL shall pay all commissions, transfer taxes and other out- of-pocket transaction costs, including the expenses and compensation of the Exchange Agent, incurred in connection with such sale of Excess Shares. Until the net proceeds of such sale have been distributed to the holders of Certificates, the Exchange Agent will hold such proceeds in trust for such former holders of Certificates (the "Fractional Shares Fund"). As soon as practicable after the determination of the amount of cash to be paid to holders of certificates in lieu of any fractional interests, the Exchange Agent shall make available in accordance with this Agreement such amounts to such holders of Certificates; (e) notwithstanding anything in this Agreement, any issued and outstanding NHL Shares held by a person who objects to the Merger (a "Dissenting Stockholder") and complies with all the provisions of Delaware Law concerning the right of holders NHL Shares to dissent from the Merger and require appraisal of their NHL Shares ("Dissenting Shares") shall not be converted as described in Section 1.2(a) but shall become the right to receive such consideration as may be determined to be due to such Dissenting Stockholder pursuant to Delaware Law. If, after the Effective Time, such Dissenting Stockholder withdraws his demand for appraisal or fails to perfect or otherwise loses his right to appraisal, in any case pursuant to Delaware Law, his NHL Shares shall be deemed to be converted as of the Effective Time into the Conversion Consideration. NHL shall give HLR (i) prompt notice of any demands for appraisal of NHL Shares received by NHL and (ii) the opportunity to participate in and direct all negotiations and proceedings with respect to any such demands. NHL shall not, without the prior written consent of HLR, make any payment with respect to, or settle, offer to settle or otherwise negotiate, any such demands. SECTION 1.3. Surrender and Payment. (a) Prior to the Effective Time, HLR and NHL shall appoint a mutually acceptable bank or trust company as agent (the "Exchange Agent") for the purpose of exchanging certificates in connection with the NHL Share Conversion in accordance with the terms of this Agreement. At or prior to the Effective Time, HLR shall deposit in trust with the Exchange Agent $135,651,100 (the "HLR Cash Consideration"). At or prior to the Effective Time, Roche shall provide to NHL $51,048,900 (the "Roche Warrant Consideration") in respect of Roche's purchase of 8,325,000 Warrants (as defined in Section 1.4(a)) pursuant to Section 1.4(b) (the "Roche Warrants"). At or prior to the Effective Time, NHL shall, subject to Section 7.2, deposit in trust with the Exchange Agent (x) $288,000,000 (the "NHL Cash Consideration") and (y) the Roche Warrant Consideration received from Roche. The HLR Cash Consideration, the NHL Cash Consideration and the Roche Warrant Consideration are referred to collectively as (the "Cash Consideration Fund"). The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Cash Consideration contemplated to be issued as part of the NHL Share Conversion out of the Cash Consideration Fund. The Cash Consideration Fund shall not be used for any other purpose. (b) As soon as reasonably practicable after the Effective Time, the Surviving Corporation shall cause the Exchange Agent to mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of NHL Shares (the "Certificates") (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as NHL may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for certificates representing the NHL Shares and Cash Consideration into which such Certificates shall have been converted pursuant to the NHL Share Conversion. Upon surrender of a Certificate for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by NHL, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate shall be entitled to receive in exchange therefor a certificate representing that number of NHL Shares and the Cash Consideration which such holder has the right to receive pursuant to the provisions of this Article (and cash, if any, in lieu of fractional shares pursuant to Section 1.2(d)). In the event of a transfer of ownership of NHL Shares which is not registered in the transfer records of NHL, a certificate representing the proper number of shares of NHL Shares may be issued and the Cash Consideration may be paid (and cash, if any, in lieu of fractional shares) to a Person other than the Person in whose name the Certificate so surrendered is registered, if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment shall pay any transfer or other taxes required by reason of the issuance of NHL Shares and payment of Cash Consideration (and cash, if any, in lieu of fractional shares) to a Person other than the registered holder of such Certificate or establish to the satisfaction of HLR that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 1.3, each Certificate shall be deemed at any time after the Effective Time to represent only the number of NHL Shares and the right to receive Cash Consideration (and cash, if any, in lieu of fractional shares) to which such holder is entitled pursuant to the NHL Share Conversion, and the holder of such Certificate shall cease to have any rights with respect to the number of NHL Shares represented by such Certificate immediately prior to the Effective Time in excess of the number of NHL Shares to which such holder is entitled pursuant to the NHL Share Conversion except as otherwise provided herein or by law. No interest will be paid or will accrue on any Conversion Consideration (or cash, if any, payable in lieu of fractional shares). (c) From and after the Effective Time, there shall be no further registration of transfers of Certificates. (d) The Cash Consideration Fund and the Fractional Shares Fund shall be invested by the Exchange Agent as directed by HLR in consultation with the Surviving Corporation (so long as such directions do not impair the rights of the holders of NHL Shares) in direct obligations of the United States of America, obligations for which the full faith and credit of the United States of America is pledged to provide for the payment of principal and interest, commercial paper rated of the highest quality by Moody's Investors Services, Inc. or Standard & Poor's Corporation or certificates of deposit issued by a commercial bank having combined capital, surplus and undivided profits aggregating at least $500,000,000 (provided that no such investment made prior to the thirtieth day after the Effective Time shall mature more than seven days after such investment is made), and any net earnings with respect thereto shall be paid to the Surviving Corporation as and when requested by the Surviving Corporation. (e) Any portion of the Cash Consideration Fund and the Fractional Shares Fund which remains undistributed six months after the Effective Time shall be delivered to the Surviving Corporation upon demand, and any holders of such NHL Shares who have not theretofore complied with this Article 1 shall thereafter look only to the Surviving Corporation for the Cash Consideration (and cash, if any, payable in lieu of fractional shares) to which they are entitled. (f) Neither HLR nor the Surviving Corporation shall be liable to any holder of NHL Shares for any such Cash Consideration (or cash, if any, payable in lieu of fractional shares) or any certificates for any NHL Shares delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. (g) The Surviving Corporation shall be entitled to deduct and withhold from the Cash Consideration (and cash, if any, payable in lieu of fractional shares) otherwise payable pursuant to this Agreement to any holder of NHL Shares such amounts as the Surviving Corporation is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of such NHL Shares in respect of which such deduction and withholding was made by the Surviving Corporation. SECTION 1.4. Warrants. (a) NHL currently intends to declare a dividend payable to holders of NHL Common Stock of record as of the third Business Day prior to the date of the NHL Stockholder Meeting, which dividend shall consist of .16308 of a warrant for each NHL Share outstanding on such date, each such Warrant (a "Warrant" and together with the Roche Warrants, the "Warrants") representing the right to purchase one newly issued share of NHL Common Stock and which shall be in the form and have substantially the terms and conditions set forth in the Warrant Agreement to be entered into between NHL and a warrant agent, which Warrant Agreement shall be satisfactory to NHL and to Roche (the "Warrant Agreement"). The Warrant Agreement will contain customary terms and conditions and will provide, among other things, for the issuance of the Warrants to be dividended to holders of record of NHL Common Stock on the third Business Day preceding the date of the NHL Stockholder Meeting, for the issuance of the Roche Warrants, that each Warrant may be exercised on the fifth anniversary (the "Expiration Date") of issuance to purchase one share of Common Stock at a purchase price of $22.00 per share (subject to adjustments), and that NHL shall have the option, exercisable by notice 60 days prior to the Expiration Date, to redeem the Warrants on the Expiration Date for a cash redemption price per Warrant equal to the average closing price of the NHL Common Stock over a specified period prior to the Expiration Date minus the exercise price. It is understood and agreed by the parties hereto that the representations and warranties of NHL with respect to the Warrant Agreement set forth in Article 3 hereof are based upon the assumption that the Warrant Agreement will conform to the description set forth in the preceding sentence. (b) At or prior to the Effective Time, Roche shall cause to be delivered to NHL an amount in cash equal to the Roche Warrant Consideration in payment of the aggregate purchase price of $51,048,900 payable in respect of the Roche Warrants. In consideration of receipt of such payment, NHL shall issue and deliver to Roche pursuant to the Warrant Agreement a warrant certificate or certificates (in such denominations as requested by Roche) representing the Roche Warrants so purchased. SECTION 1.5. Stock Options. (a) Each employee stock option or right to acquire NHL Shares under NHL's 1988 and 1994 Stock Option Plans (such rights being referred to as "Employee Stock Options") outstanding on the date hereof shall be deemed fully vested and, immediately prior to the Effective Time, NHL shall use reasonable efforts, including with respect to obtaining consents, to cause each Employee Stock Option to be canceled and terminated in exchange for an amount in cash and NHL Shares (in the proportions set forth below) equal to the product of (i) the number of NHL Shares subject to such Employee Stock Option immediately prior to the Effective Time and (ii) the excess of (1) $18.50 over (2) the per share exercise price of such Employee Stock Option (such product, the "Option Value Amount"). The Option Value Amount shall be payable at the Effective Time as follows: 40% of such amount (the "Option Cash Amount") shall be payable in cash, and 60% of such amount (the "Option Stock Amount") shall be payable in the number of NHL Shares obtained by dividing the Option Stock Amount by $15.42; provided that any fractional share resulting from such calculation shall be paid in cash, with the value of a whole share for such purpose assumed to be $15.42. All amounts payable to this Section 1.5(a) shall be subject to any required withholding of taxes and shall be paid without interest thereon. (b) Notwithstanding the foregoing Section 1.5(a), the Employee Stock Options with respect to which the requisite consents are not obtained shall not be canceled, but instead shall be immediately converted as of the Effective Time into the right ("Adjusted Option") to purchase the Option Conversion Number (as defined below) of NHL Shares. Each Adjusted Option will have substantially the same terms as the Employee Stock Option to which it is related, except that: (i) the Adjusted Option shall be deemed fully vested and (ii) the exercise price of an Adjusted Option shall be an amount equal to the exercise price of the Employee Stock Option related to such Adjusted Option as of the date of this Agreement divided by the Conversion Number (as defined below). The "Option Conversion Number" for any Adjusted Option shall be equal to the number of NHL Shares purchasable pursuant to the Employee Stock Option related to such Adjusted Option as of the date of this Agreement multiplied by the Conversion Number. The "Conversion Number" shall be a number equal to (i) the sum of (x) the product of (A) the average closing price of a share of NHL Common Stock on the NYSE Composite Tape for the period of five consecutive trading days beginning on the trading day following the date on which the Effective Time occurs (the "Post Merger Value") and (B) 0.72 and (y) $6.60 divided by (ii) the Post Merger Value. ARTICLE 2 THE SURVIVING CORPORATION SECTION 2.1. Certificate of Incorporation. The certificate of incorporation of NHL in effect at the Effective Time shall, except as may be amended to give effect, as necessary, to the provisions of this Agreement and the HLR Stockholder Agreement, be the certificate of incorporation of the Surviving Corporation until amended in accordance with applicable law. SECTION 2.2. Bylaws. The bylaws of NHL in effect at the Effective Time shall, except as may be amended to give effect, as necessary, to the provisions of this Agreement and the HLR Stockholder Agreement, be the bylaws of the Surviving Corporation until amended in accordance with applicable law. SECTION 2.3. Directors and Officers. From and after the Effective Time, (i) the number of directors constituting the Board of Directors of NHL shall be seven and shall be comprised of three members designated by HLR and four persons who are mutually acceptable to NHL and HLR, until successors are duly elected or appointed and qualified in accordance with applicable law and the HLR Stockholder Agreement, and (ii) the executive officers of the Surviving Corporation shall be such Persons as are identified on a certificate delivered by HLR to NHL prior to the Effective Time, which certificate, upon the delivery thereof, shall be deemed to be incorporated into this Agreement for purposes hereof. ARTICLE 3 REPRESENTATIONS AND WARRANTIES OF NHL NHL represents and warrants to RBL and HLR that, except as set forth on the disclosure schedule delivered by NHL to HLR prior to the execution of this Agreement (the "NHL Disclosure Schedule"): SECTION 3.1. Corporate Existence and Power. NHL is a corporation duly incorporated, validly existing and in good standing under the laws of the jurisdiction in which it is incorporated and has all corporate powers required to carry on its business as now being conducted. NHL is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction where the character of the property owned or leased by it or the nature of its activities makes such qualification necessary, except for those jurisdictions where the failure to be so qualified would not, individually or in the aggregate, have a material adverse effect on the business, financial condition, assets, results of operations or prospects of NHL and its Subsidiaries, taken as a whole (an "NHL Material Adverse Effect"), or NHL's ability to perform its obligations under this Agreement, the HLR Stockholder Agreement, the Warrant Agreement or the Sharing and Call Option Agreement. NHL has heretofore delivered to HLR true and complete copies of its certificate of incorporation and bylaws and the certificate of incorporation and bylaws of each of its Subsidiaries, in each case as currently in effect. For purposes of this Agreement, "Subsidiary" of any Person means any entity of which securities or other ownership interests having ordinary voting power to elect a majority of the board of directors or other Persons performing similar functions are directly or indirectly owned by such Person.

Each of this Agreement and the Sharing and Call Option Agreement constitutes, and each of the HLR Stockholder Agreement, and the Warrant Agreement when executed and delivered by NHL, will constitute, a valid and binding agreement of NHL. SECTION 3.3. Governmental Authorization. The execution, delivery and performance by NHL of this Agreement, the HLR Stockholder Agreement, the Warrant Agreement and the Sharing and Call Option Agreement, and the consummation by NHL of the transactions contemplated hereby (including, without limitation, the Merger, the delivery of the Conversion Consideration, the issuance of the HLR-NHL Shares and of the Warrants and the NHL Common Stock issuable thereunder) and thereby require no action by, or filing with, any governmental body, agency, official or authority other than (i) the filing of a certificate of merger in accordance with Delaware Law and any amendments to NHL's certificate of incorporation as referred to in Section 2.1, (ii) compliance with any applicable requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act"), (iii) compliance with any applicable requirements of the Securities Exchange Act of 1934, as amended (the "1934 Act"), (iv) compliance with any applicable requirements of the Securities Act of 1933, as amended (the "1933 Act"), (v) compliance with any applicable foreign or state securities or "blue sky" laws and (vi) such actions by or filings with governmental bodies, agencies, officials or authorities, the failure of which to obtain or make would not reasonably be expected to have, individually or in the aggregate (A) an NHL Material Adverse Effect, (B) impair the ability of NHL to perform its obligations under this Agreement, the HLR Stockholder Agreement, the Warrant Agreement or the Sharing and Call Option Agreement, or (C) prevent the consummation of any of the transactions contemplated by this Agreement, the HLR Stockholder Agreement, the Warrant Agreement or the Sharing and Call Option Agreement. SECTION 3.4. Non-Contravention. The execution, delivery and performance by NHL of this Agreement, the HLR Stockholder Agreement, the Warrant Agreement and the Sharing and Call Option Agreement do not, and the consummation by NHL of the transactions contemplated hereby and thereby do not and will not (i) contravene or conflict with the certificate of incorporation (taking into account appropriate amendments contemplated by Section 2.1 hereof) or the bylaws of NHL or the organizational documents of any of its Subsidiaries, (ii) assuming compliance with the matters referred to in Section 3.3, contravene or conflict with or constitute a violation of any provision of any law, regulation, judgment, injunction, order or decree binding upon or applicable to NHL or any of its Subsidiaries, (iii) constitute a default under or give rise to a right of termination, cancellation or acceleration of any right or obligation of NHL or any of its Subsidiaries or to a loss of any benefit to which NHL or any of its Subsidiaries is entitled under any provision of any agreement, contract or other instrument binding upon NHL or any of its Subsidiaries or any license, franchise, permit or other similar authorization held by NHL or any of its Subsidiaries, or (iv) result in the creation or imposition of any Lien on any asset of NHL or any of its Subsidiaries, except, with respect to clauses (ii), (iii) and (iv) above, for contraventions, conflicts, defaults, rights of termination, cancellation or acceleration, losses of benefits and creation or imposition of Liens that would not reasonably be expected to have, individually or in the aggregate, an NHL Material Adverse Effect. For purposes of this Agreement, "Lien" means, with respect to any asset, any mortgage, lien, pledge, charge, security interest or encumbrance of any kind in respect of such asset. SECTION 3.5. Capitalization. The authorized capital stock of NHL consists of 10,000,000 shares of preferred stock, par value $0.10 per share ("NHL Preferred Stock"), and 220,000,000 NHL Shares. As of December 12, 1994, (a) there were issued and outstanding 84,761,817 NHL Shares and no shares of NHL Preferred Stock, (b) no NHL Shares were held in NHL's treasury and (c) 1,756,507 NHL Shares were reserved for issuance upon exercise of outstanding Employee Stock Options (of which options to purchase an aggregate of 3,527,876 NHL Shares were vested and exercisable).

NHL has delivered to HLR a list of all of NHL's Subsidiaries. There are no partnerships or joint venture arrangements or other business entities in which NHL or any Subsidiary of NHL owns an equity interest that is material to the business of NHL and its Subsidiaries, taken as a whole.

SECTION 3.9. Disclosure Documents. (a) None of the information supplied or to be supplied by NHL specifically for inclusion or incorporation by reference in (i) the registration statement on Form S-4 to be filed with the SEC by NHL in connection with the issuance of NHL Shares in the Merger (the "Registration Statement", which Registration Statement will include a resale prospectus) will, at the time the Registration Statement is filed with the SEC, at any time it is amended or supplemented or at the time it becomes effective under the 1933 Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) the proxy statement relating to the approval by the stockholders of NHL of the Merger and certain other matters, together with all other related proxy materials prepared in connection with the NHL Stockholder Meeting relating to the Merger (the "NHL Proxy Statement") will, at the date the NHL Proxy Statement is first mailed to NHL's stockholders or at the time of the NHL Stockholder Meeting, contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

SECTION 3.12. Litigation. Except as set forth in the SEC Documents, there is no action, suit, investigation or proceeding pending, or to the knowledge of NHL threatened (or, to the knowledge of NHL or its Subsidiaries, any basis therefor), against NHL or any of its Subsidiaries or any of their respective properties before any court or arbitrator or any governmental body, agency or official that could reasonably be expected to (A) have an NHL Material Adverse Effect, (B) impair the ability of NHL to perform its obligations under this Agreement, the HLR Stockholder Agreement, the Warrant Agreement or the Sharing and Call Option Agreement or (C) prevent or materially delay the consummation of any of the transactions contemplated by this Agreement, the HLR Stockholder Agreement, the Warrant Agreement or the Sharing and Call Option Agreement.

(f)Except as disclosed in the NHL Disclosure Schedule, neither NHL nor any of its Subsidiaries has any current or projected liability in respect of post-employment or post-retirement health and medical benefits for retired or former employees of NHL and its Subsidiaries, except as required to avoid excise tax under Section 4980B of the Code; and no condition exists that would prevent NHL or any of its Subsidiaries from amending or terminating any NHL Employee Plan or NHL Benefit Arrangement providing health or medical benefits in respect of any active employee of NHL or any of its Subsidiaries other than limitations imposed under the terms of a collective bargaining agreement. (g)Except as disclosed in the NHL Disclosure Schedule, there has been no amendment to, written interpretation or announcement (whether or not written) by NHL or any of its ERISA Affiliates relating to, or change in employee participation or coverage under, any NHL Employee Plan or NHL Benefit Arrangement which would increase materially the expense of maintaining such NHL Employee Plan or NHL Benefit Arrangement above the level of the expense incurred in respect thereof for the fiscal year ended on December 31, 1993 (other than those that would not result in the representation and warranty set forth in Section 3.10(j) becoming untrue as of the Effective Time). (h)Neither NHL nor any of its Subsidiaries is a party to or subject to any collective bargaining or other labor union contracts applicable to persons employed by NHL or its Subsidiaries and no collective bargaining agreement is being negotiated by NHL or any of its Subsidiaries.

SECTION 3.15. Compliance with Laws; Permits. (a) Except as set forth in the SEC Documents and except for violations which do not have and would not reasonably be expected to have, individually or in the aggregate, an NHL Material Adverse Effect, neither NHL nor any of its Subsidiaries is in violation of, or has violated, any applicable provisions of any laws, statutes, ordinances or regulations or any term of any judgment, decree, injunction or order outstanding against it. (b)As of the date of this Agreement, each of NHL and each of its Subsidiaries is in possession of all franchises, grants, authorizations, licenses, permits, easements, variances, exemptions, consents, certificates, identification numbers, approvals and orders (collectively, the "NHL Permits") necessary to own, lease and operate its properties and to carry on its business as it is now being conducted, and there is no action, proceeding or investigation pending or, to the knowledge of NHL, threatened regarding suspension or cancellation of any of the NHL Permits, except where the failure to possess, or the suspension or cancellation of, such NHL Permits would not reasonably be expected to have, individually or in the aggregate, an NHL Material Adverse Effect. SECTION 3.16. Finders' Fees. Except for Morgan Stanley & Co. Incorporated ("Morgan Stanley"), whose fees in the amount previously disclosed to HLR will be paid by NHL, and as contemplated herein, there is no investment banker, broker, finder or other intermediary which has been retained by or is authorized to act on behalf of, NHL or any of its Subsidiaries which might be entitled to any fee or commission from HLR or any of its Affiliates upon consummation of the transactions contemplated by this Agreement.

The Board of Directors of NHL has approved the HLR Stockholder Agreement, the Merger, the Warrants, the Sharing and Call Option Agreement and this Agreement, and such approval is sufficient to render inapplicable to the HLR Stockholder Agreement, the Merger, the Warrants, the Sharing and Call Option Agreement and this Agreement and the transactions contemplated or permitted thereby and hereby, the provisions of Section 203 of Delaware Law. To NHL's knowledge, no other state takeover statute or similar statute or regulation applicable to NHL applies or purports to apply to the HLR Stockholder Agreement, the Merger, the Warrants, the Sharing and Call Option Agreement or this Agreement, or any of the transactions contemplated thereby and hereby. SECTION 3.20. Opinion of Financial Advisor. NHL has received the opinion of Morgan Stanley & Co. Incorporated dated the date of this Agreement to the effect that the aggregate consideration to be received by the stockholders of NHL in connection with the Merger, when taken together with the Warrants to be dividended to such stockholders, is fair, from a financial point of view, to such stockholders. SECTION 3.21. Vote Required. The affirmative vote of the holders of a majority of the outstanding shares of NHL Common Stock is the only vote of the holders of any class or series of NHL securities necessary to approve the Merger and the other transactions contemplated by this Agreement and any amendments to the certificate of incorporation of NHL as referred to in Section 2.1.

Corporate Existence and Power. Each of HLR and RBL is a corporation duly incorporated, validly existing and in good standing under the laws of the jurisdiction in which it is incorporated and has all corporate powers required to carry on its business as now being conducted. Each of HLR and RBL is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction where the character of the property owned or leased by it or the nature of its activities makes such qualification necessary, except for those jurisdictions where the failure to be so qualified would not, individually or in the aggregate, have a material adverse effect on the business, financial condition, results of operations or prospects of RBL and its Subsidiaries, taken as a whole (a "RBL Material Adverse Effect"), or RBL's ability to perform its obligations hereunder or under the HLR Stockholder Agreement. RBL has heretofore delivered to NHL true and complete copies of its certificate of incorporation and bylaws and the certificate of incorporation and bylaws of each of its Subsidiaries, in each case as currently in effect. SECTION 4.2. Corporate Authorization. The execution, delivery and performance by each of HLR and RBL of this Agreement, the HLR Stockholder Agreement and the Sharing and Call Option Agreement and the consummation by HLR and RBL of the transactions contemplated hereby and thereby are within their respective corporate powers and, except for any required approval by HLR as RBL's sole stockholder in connection with the consummation of the Merger, have been duly authorized by all necessary corporate action.

(ii) HLR shall promptly indemnify the Surviving Corporation or any other member of the NHL Group for any liability for Taxes or loss arising as a result of the breach by HLR or any of its Subsidiaries of its obligations under Section 8.2(e)(i), the representation contained in Section 4.12(k) or the representations and covenants contained in the HLR Representations Letter (as defined in Section 8.2(i)) that results in the Merger failing to qualify as a reorganization within the meaning of Section 368(a)(1) of the Code (or any comparable provision of state or local tax law), or in the recognition of gain by RBL pursuant to Section 357(c) of the Code (or any other provision of state or local tax law). (f) HLR shall promptly indemnify the Surviving Corporation or any other member of the NHL Group for (i) all Taxes of RBL and its Subsidiaries for any Pre-Merger Tax Period, but, with respect to Taxes (other than federal income taxes) for any Pre-Merger Tax Period with respect to which no return has been filed (and is not yet due) at the Effective Time, only to the extent in each case that such Tax exceeds the portion of the Tax shown as due on the return which includes such Pre-Merger Tax Period that is attributable to such Pre-Merger Tax Period; and (ii) all Taxes of any member of the HLR Group (other than RBL and its Subsidiaries, and for any Post-Merger Tax Period, the Surviving Corporation and its Subsidiaries) with respect to any Pre-Merger or Post-Merger Tax Period. (g) None of the Surviving Corporation, any other member of the NHL Group, HLR, or any other member of the HLR Group shall settle or pay any claim for Taxes with respect to which the Surviving Corporation or HLR, as the case may be, is obligated to make any payment pursuant to Sections 8.2(d)(ii), 8.2(e)(ii) or 8.2(f) without the consent of the Surviving Corporation or HLR, as the case may be, which consent shall not be unreasonably withheld. (h) NHL agrees to execute and deliver a letter, dated as of the date on which the Effective Time occurs, in the form set forth in Exhibit B hereto (the "NHL Representations Letter") to each of counsel for NHL and counsel for RBL and HLR prior to the Effective Time. (i) HLR agrees to execute and deliver a letter, dated as the date on which the Effective Time occurs, in the form set forth in Exhibit C hereto (the "HLR Representations Letter") to each of counsel for NHL and counsel for RBL and HLR prior to the Effective Time. SECTION 8.3. Termination of Existing Tax Sharing Agreements. Any and all existing Tax Sharing Agreements between RBL or any Subsidiary of RBL and any member of the HLR Group shall be terminated as of the date on which the Effective Time occurs. After such date neither RBL, any Subsidiary of RBL, HLR nor any Subsidiary of HLR shall have any further rights or liabilities thereunder. This Agreement shall be the sole Tax sharing agreement relating to RBL or any Subsidiary of RBL for all Pre-Merger and Post-Merger Tax Periods. SECTION 8.4. Tax Sharing. (a) (i) Immediately before the Effective Time, RBL shall pay to HLR an amount equal to the federal income Taxes of RBL and its Subsidiaries with respect to the Pre-Merger Tax Period that ends on the date of the Effective Time. The amount of such payment in respect of such Taxes shall be based upon HLR's reasonable good faith estimates of the amounts of federal taxable income of RBL and its Subsidiaries (determined as if RBL and its Subsidiaries filed a consolidated federal income Tax return with RBL as the common parent) for such Pre-Merger Tax Period and an effective federal tax rate of 35%, and reduced by the amount of any payments on account of such Taxes previously paid by RBL or any of its Subsidiaries to HLR, any other member of the HLR Group (other than RBL and its Subsidiaries) or the IRS. (ii) At such time as the HLR Group prepares its federal income tax return for such Pre-Merger Tax Period, it shall deliver to the Surviving Corporation a pro forma return (each a "Pro Forma Return") for RBL and its Subsidiaries which calculates the amount of federal income Taxes that RBL and its Subsidiaries would have paid with respect to such Pre-Merger Tax Period had RBL timely filed its own consolidated federal income Tax return including its Subsidiaries (with RBL as the common parent) for such Pre-Merger Tax Period. The Surviving Corporation shall have the right at its expense to review all work papers and procedures used to prepare such Pro Forma Return. Unless the Surviving Corporation timely objects as specified in this Section 8.4(a)(ii) such Pro Forma Return shall be binding on the parties without further adjustment. If the Surviving Corporation objects to any item on such Pro Forma Return, it shall notify HLR in writing that it so objects, specifying with particularity any such item and the factual or legal basis for its objection, within 10 days after delivery of such Pro Forma Return. If HLR and the Surviving Corporation are unable to reach agreement on such items within 20 days after HLR receives such notice, the disputed items shall be resolved by a nationally recognized accounting firm with no material relationship to the Surviving Corporation, HLR or any of their Affiliates, chosen within 5 days of the date upon which the need to retain such firm arises by and mutually acceptable to both HLR and the Surviving Corporation. The costs and expenses of retaining such firm shall be borne equally by HLR and the Surviving Corporation. Upon resolution by such firm of all such items and adjustment of the Pro Forma Return to reflect such resolution, the Pro Forma Return shall be binding on the parties without further adjustment. Once the Pro Forma Return has become binding, HLR shall promptly pay the Surviving Corporation, or the Surviving Corporation shall promptly pay HLR, as appropriate, an amount equal to (A) the difference between (x) the sum of the liabilities shown on the Pro Forma Return and (y) the sum of all payments previously made by RBL (including any payment pursuant to Section 8.4(a)(i)) or any Subsidiary with respect thereto to HLR, any other member of the HLR Group (other than RBL and its Subsidiaries) or the IRS, and (B) interest on such difference, which shall accrue at a rate equal to the three-month London Interbank Offered Rate plus 0.5% from the Effective Time until the date payment is made pursuant to this sentence. (b) At such time as the HLR Group prepares its federal income tax return for its 1994 tax year, it shall deliver to the Surviving Corporation a pro forma return (each a "Pro Forma Return") for RBL and its Subsidiaries which calculates the amount of federal income Taxes that RBL and its Subsidiaries would have paid with respect to such tax year had RBL timely filed its own consolidated federal income Tax return including its Subsidiaries (with RBL as the common parent) for such tax year. The Surviving Corporation shall have the right at its expense to review all work papers and procedures used to prepare such Pro Forma Return. Unless the Surviving Corporation timely objects as specified in this Section 8.4(b) such Pro Forma Return shall be binding on the parties without further adjustment. If the Surviving Corporation objects to any item on such Pro Forma Return, it shall notify HLR in writing that it so objects, specifying with particularity any such item and the factual or legal basis for its objection, within 10 days after delivery of such Pro Forma Return. If HLR and the Surviving Corporation are unable to reach agreement on such items within 20 days after HLR receives such notice, the disputed items shall be resolved by a nationally recognized accounting firm with no material relationship to the Surviving Corporation, HLR or any of their Affiliates, chosen within 5 days of the date upon which the need to retain such firm arises by and mutually acceptable to both HLR and the Surviving Corporation. The costs and expenses of retaining such firm shall be borne equally by HLR and the Surviving Corporation. Upon resolution by such firm of all such items and adjustment of the Pro Forma Return to reflect such resolution, the Pro Forma Return shall be binding on the parties without further adjustment. Once the Pro Forma Return has become binding, HLR shall promptly pay the Surviving Corporation, or the Surviving Corporation shall promptly pay HLR, as appropriate, an amount equal to (A) the difference between (x) the sum of the liabilities shown on the Pro Forma Return and (y) the sum of all payments previously made by RBL or any Subsidiary with respect thereto to HLR, any other member of the HLR Group (other than RBL and its Subsidiaries) or the IRS, provided that, where (x) exceeds (y), the Surviving Corporation shall be obligated to pay to HLR such difference only to the extent that it does not exceed the greatest amount of intercompany account balances in respect of such Taxes that, if in existence as of December 31, 1994, in addition to the other intercompany account balances existing as of that date and actually taken into account in formulating the Pro Forma Balance Sheet pursuant to Section 6.7(a), could have been eliminated by payment rather than capitalization in formulating such Pro Forma Balance Sheet, and (B) interest on the amount required to be paid pursuant to clause (A) (determined taking into account the proviso thereto), which shall accrue at a rate equal to the three-month London Interbank Offered Rate plus 0.5% from the Effective Time until the date payment is made pursuant to this sentence. (c) The Surviving Corporation shall prepare or cause to be prepared, and shall deliver to HLR, each return with respect to state or local income, franchise, sales and use Taxes for any Pre-Merger Tax Period for which no return has been filed (and is not yet due) as of the Effective Time and which relates, in whole or in part, to Taxes with respect to which HLR may be required to indemnify the Surviving Corporation or any other member of the N Co. Group at least 90 days prior to the due date for such return. HLR shall have the right at its expense to review all work papers and procedures used to prepare such return. Unless HLR timely objects as specified in this Section 8.4(c), the Surviving Corporation or its Subsidiary, as appropriate, shall file such return without further adjustment with the appropriate taxation authority, and pay the Tax shown as due thereon. If HLR objects to any item on such return, it shall notify the Surviving Corporation in writing that it so objects, specifying with particularity any such item and the factual or legal basis for its objection, within 10 days after delivery of such return. If HLR and the Surviving Corporation are unable to reach agreement on such items within 20 days after the Surviving Corporation receives such notice, the disputed items shall be resolved by a nationally recognized accounting firm with no material relationship to the Surviving Corporation, HLR or any of their Affiliates, chosen within 5 days of the date upon which the need to retain such firm arises by and mutually acceptable to both HLR and the Surviving Corporation. The costs and expenses of retaining such firm shall be borne equally by HLR and the Surviving Corporation. Upon resolution by such firm of all such items and adjustment of the return to reflect such resolution, the Surviving Corporation or its Subsidiary, as appropriate, shall file such return without further adjustment with the appropriate taxation authority, and pay the Tax shown as due thereon. SECTION 8.5. Cooperation on Tax Matters. The Surviving Corporation and HLR agree to furnish or cause to be furnished to each other, upon request, as promptly as practicable, such information (including access to books and records) and assistance relating to RBL and its Subsidiaries as is reasonably necessary for the filing of any return, for the preparation for any audit, and for the prosecution or defense of any claim, suit or proceeding relating to any proposed adjustment, provided that (i) HLR shall not be obligated to furnish or cause to be furnished any information with respect to Genentech, Inc. and any of its Subsidiaries, and (ii) in the case of information which also relates, in whole or in part, to members of the HLR Group other than RBL and its Subsidiaries, in order to ensure the confidentiality of the HLR Group's commercial or proprietary information to the maximum extent feasible HLR shall be obligated to furnish or to be caused to be furnished such information upon request only to an independent advisor with no material relationship to the Surviving Corporation, HLR or any of their Affiliates chosen by and mutually acceptable to both HLR and the Surviving Corporation. The Surviving Corporation and HLR agree to retain or cause to be retained all books and records pertinent to RBL and its Subsidiaries until the end of the fifth year after the Effective Time, and to abide by or cause the abidance with all record retention agreements entered into with any taxation authority, in the case of the Surviving Corporation, but only to the extent such agreements have been disclosed in writing to NHL prior to the date hereof. The Surviving Corporation agrees to give HLR reasonable notice prior to transferring, discarding or destroying any such books and records relating to Tax matters and, if HLR so requests, the Surviving Corporation shall allow HLR to take possession of such books and records at HLR's cost and expense. The Surviving Corporation and HLR shall cooperate with each other in the conduct of any audit or other proceedings involving RBL or any of its Subsidiaries for any Tax purposes and each shall execute and deliver such powers of attorney and other documents as are necessary to carry out the intent of this subsection.

SECTION 2.5 Notice to Holders with Respect to Exercise and Redemption. Not earlier than 90 days nor later than 60 days prior to the Expiration Date, the Company shall deliver to the Warrant Agent notice in writing, which notice shall be irrevocable, stating whether or not it shall have elected to redeem the Warrants on the Expiration Date in accordance with Section 2.7 Promptly after receipt of the Company's notice, the Warrant Agent shall mail a notice to all Holders at the addresses set forth on the Warrant Register to the effect that (as applicable) each outstanding Warrant shall be redeemed for the Redemption Amount on the Expiration Date or that such Warrants shall not be redeemed and describing the exercise procedure set forth in Section 2.6 (which notice shall include the statement that the Warrants will terminate and become void as of the Close of Business on the Expiration Date and that failure by a Holder to comply with the exercise procedures will result in the forfeiture of such Holder's rights with respect to such Holder's Warrants). SECTION 2.6 Exercise of Warrants. (a) Subject to the provisions of this Agreement, each Warrant shall be exercisable only prior to the Close of Business on the Expiration Date and only if the Company shall not have duly elected to effect a Redemption pursuant to Section 2.7. The Warrants shall expire at and become null and void and have no value and no Person shall have any rights thereto as of the Close of Business on the Expiration Date, provided, however, that, notwithstanding such expiration, Holders that have properly exercised Warrants in accordance with this Section 2.6 shall be entitled to receive Warrant Shares with respect to such Holders' Warrants as provided in subsection (b) unless the Company shall have elected to effect a Redemption pursuant to Section 2.7, in which case each Holder shall be entitled to received the Redemption Amount as described in Section 2.7. (b) Subject to Section 2.7, for each Warrant held, the Holder thereof shall have the right to purchase from the Company (and the Company shall issue and sell to such Holder) one fully paid and non-assessable share of Common Stock at the Exercise Price (in each case subject to adjustment as hereinafter provided) upon (i) surrender to the Warrant Agent, at a Warrant Agent Office of the Warrant Certificate evidencing such Warrant, with the form of election to exercise on the reverse thereof properly completed and signed by the Holder or Holders thereof or by the duly appointed legal representative thereof or by a duly authorized attorney, and (ii) payment of the Exercise Price for the number of Warrant Shares in respect of which such Warrant is being exercised. Such surrender and payment (if applicable) may be made and shall be accepted by the Warrant Agent at any time during the 45 day period immediately preceding the Close of Business on the Expiration Date, but any Warrants so surrendered shall not be deemed to be exercised until the Expiration Date. Payment of the Exercise Price shall be made by a certified or official bank check payable to the order of the Warrant Agent for the account of the Company or by wire transfer of funds to an account designated by the Company for such purpose. The Warrants evidenced by a Warrant Certificate shall be exercisable, at the election of the Holder thereof, either in their entirety or in part. Except as expressly provided to the contrary in Article 4, no adjustments shall be made for any cash dividends or other cash distributions on Warrant Shares issuable upon the exercise of a Warrant. (c) Upon the surrender of each Warrant Certificate in accordance with subsection (b) above and payment of the per share Exercise Price (and an amount representing any transfer taxes payable with respect to the issuance of the relevant Warrant Shares) immediately following the Expiration Date, the Company shall issue and cause its transfer agent for the Common Stock ("Transfer Agent") to deliver with all reasonable dispatch to or upon the written order of the Holder and in such name or names as such Holder may designate, a certificate or certificates for the number of full Warrant Shares so purchased upon the exercise of such Warrant or Warrants together with cash as provided in Section 2.12 in respect of any Fractional Warrant Share (as defined below) otherwise issuable upon such exercise. Such certificate or certificates shall be deemed to have been issued and any person so designated to be named therein shall be deemed to have become a holder of record of such Warrant Shares as of the Expiration Date; provided, however, that if, at such date, the transfer books for the Warrant Shares shall be closed, the certificates for the Warrant Shares in respect of which such Warrants are then exercised shall be issuable as of the date on which such books shall next be opened and until such date Holders shall be under no duty to deliver any certificates for such Warrant Shares; provided further, however, that such transfer books, unless otherwise required by law, shall not be closed at any one time for a period longer than 20 calendar days. SECTION 2.7 Redemption. (a) Notwithstanding Section 2.6, the Company shall have the right to redeem all, but not less than all, of the Warrants on the Expiration Date by payment to each Holder as of the Expiration Date in cash of the Redemption Amount with respect to the Warrants held by such Holder as of the Expiration Date (a "Redemption"), but only if the Company shall have timely delivered to the Warrant Agent the notice of its election to redeem the Warrants referred to in Section 2.5. If the Company has elected to redeem the Warrants as herein provided, at or immediately prior to the Expiration Date, the Company shall cause to be transferred to the Warrant Agent an amount in immediately available funds equal to the aggregate Redemption Amount for all outstanding Warrants for payment by the Warrant Agent to the Holders as of the Expiration Date in respect of the Warrants held as of the Expiration Date. If the Company shall have duly elected to redeem the Warrants but the aggregate Redemption Amount is zero or less than zero, no amount shall be required to be paid by the Company in respect of the redemption of the Warrants but the Warrants shall nonetheless be deemed to have been redeemed. (b) If the Company has duly elected to redeem the Warrants and the Company determines in its sole discretion that a Market Disruption Event has occurred and is continuing on any day that but for the occurrence of a Market Disruption Event would have been a Valuation Date with respect to the determination of the Redemption Amount, then such day shall not be deemed to be a Valuation Date and the Valuation Date shall instead be deemed to be the next Trading Day on which the Company determines that no Market Disruption Event is continuing and the Valuation Period shall be extended accordingly. If the Valuation Period shall have been so extended, then the Expiration Date for purposes of the Redemption shall be deemed to be the fifth Trading Day after the end of the Valuation Period as so extended. In the event that the Company determines that a Market Disruption Event has occurred, the Company shall give telephonic notice (promptly confirmed in writing) of such event to the Warrant Agent. SECTION 2.8 Certain Action. Before taking any action that would cause an adjustment pursuant to Article 4 reducing the Exercise Price below the then par value (if any) of the Warrant Shares issuable upon exercise of the Warrants, the Company will take any corporate action that may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares at the Exercise Price as so adjusted. SECTION 2.9 No Voting Rights. Prior to the exercise of the Warrants and the issuance of Warrant Shares in respect thereof, no Holder, as such, shall be entitled to any rights of a stockholder of the Company including, without limitation, the right to receive dividends or subscription rights, the right to vote, to consent, to exercise any preemptive right, to receive any notice of meetings of stockholders for the election of directors of the Company or any other matter or to receive any notice of any proceedings of the Company, except as may be specifically provided for herein. SECTION 2.10 Warrant Shares to be Fully Paid and Nonassessable. The Company covenants that all Warrant Shares issued upon exercise of the Warrants will, upon payment of the applicable Exercise Price, delivery of properly completed forms of election to exercise and issuance of such Warrant Shares in accordance with the terms of this Agreement, be fully paid and nonassessable and free from all liens, charges and security interests created by or imposed upon the Company with respect to the issuance and holding thereof. The Company shall no less than 50 days prior to the Expiration Date (unless the Company shall have elected to effect a Redemption pursuant to Section 2.7) at all times thereafter until issuance of Warrant Shares in accordance herewith keep reserved out of its authorized shares of Common Stock a number of shares of Common Stock sufficient to provide for the exercise of all outstanding Warrants. SECTION 2.11 No Fractional Warrants. (a) No certificates or scrip representing fractional Warrants shall be issued to any Holder in the Warrant Distribution. As promptly as practicable following the Warrant Distribution Record Date, the Warrant Agent shall determine with respect to each Person entitled to receive Warrants pursuant to the Warrant Distribution the excess of (x) the number of Warrants delivered to the Warrant Agent by the Company pursuant to Section 2.2 with respect to each such Person over (y) the number of whole Warrants to be distributed with respect to such Person (such excess fraction of a Warrant being hereinafter referred to in connection with each such Person as a "Fractional Warrant"). As soon after the Warrant Distribution Record Date as practicable, the Warrant Agent, as agent for Holders otherwise entitled to receive Fractional Warrants (each, a "Fractional Warrant Holder"), shall aggregate and sell in normal transactions the Fractional Warrants for all Fractional Warrant Holders at then available prices on the NYSE. Until the net proceeds of such sale or sales (the "Fractional Warrant Proceeds") have been distributed to the Fractional Warrant Holders, the Warrant Agent shall hold the Fractional Warrant Proceeds in trust for the Fractional Warrant Holders. The Company shall pay, and deduct from the Fractional Warrant Proceeds, all commissions, transfer taxes and other out-of-pocket transaction costs, including the expenses and compensation of the Warrant Agent, incurred in connection with such sale of the Fractional Warrants. The Warrant Agent shall determine the portion of the net Fractional Warrant Proceeds to which each Fractional Warrant Holder shall be entitled, if any, by multiplying the net Fractional Warrant Proceeds amount by a fraction, the numerator of which is the Fractional Warrant to which such Fractional Warrant Holder would otherwise be entitled and the denominator of which is the aggregate Fractional Warrants to which all Fractional Warrant Holders would otherwise be entitled. As soon as practicable after the determination of the amount of Fractional Warrant Proceeds, if any, to be paid in cash to each Fractional Warrant Holder in lieu of any Fractional Warrants, the Warrant Agent shall make available such amounts, without interest, to each such Fractional Warrant Holder. (b) If Warrants are to be issued Holders pursuant to Section 4.7(h), the Company and the Warrant Agent shall, prior to such issuance, establish a procedure corresponding to the procedure described in subsection (a) above such that Holders that would otherwise receive Fractional Warrants shall instead receive the appropriate amount of the Fractional Warrant Proceeds thereof. SECTION 2.12 No Fractional Warrant Shares. Notwithstanding any adjustment pursuant to Article 4 in the number of Warrant Shares purchasable upon the exercise of a Warrant, no certificates or scrip representing fractional Warrant Shares shall be issued upon exercise of a Warrant. As promptly as practicable following the Expiration Date, if the Company shall not have elected to effect a Redemption pursuant to Section 2.7, the Transfer Agent shall determine the excess of (x) the number of Warrant Shares delivered to the Transfer Agent by the Company with respect to each Holder pursuant to Section 2.6 over (y) the aggregate number of whole Warrant Shares to be issued with respect to such Holder (such excess being hereinafter referred to in connection with each such Holder as the "Fractional Warrant Share"). As soon after the Expiration Date as practicable, the Transfer Agent, as agent for Holders otherwise entitled to receive Fractional Warrant Shares (each, a "Fractional Warrant Share Holder"), unless the Company has elected to effect a Redemption pursuant to Section 2.7, shall aggregate and sell in normal transactions the Fractional Warrant Shares for all the Fractional Warrant Share Holders at then available prices on the NYSE or on the principal United States securities exchange on which the Common Stock is listed, if any, or on NASDAQ, if the Common Stock is quoted on NASDAQ. Until the net proceeds of such sale or sales (the "Fractional Warrant Share Proceeds") have been distributed to such Holders, the Transfer Agent will hold the Fractional Warrant Share Proceeds in trust for the Fractional Warrant Share Holders. The Company shall pay, and deduct from the Fractional Warrant Share Proceeds, all commissions, transfer taxes and other out-of-pocket transaction costs, including the expenses and compensation of the Transfer Agent, incurred in connection with such sale of the Fractional Warrant Shares. The Transfer Agent shall determine the portion of the net Fractional Warrant Share Proceeds to which each Fractional Warrant Share Holder shall be entitled, if any, by multiplying the net Fractional Warrant Share Proceeds amount by a fraction, the numerator of which is the Fractional Warrant Share to which such Fractional Warrant Share Holder would otherwise be entitled and the denominator of which is the aggregate amount of Fractional Warrant Shares to which all such Fractional Warrant Share Holders would otherwise be entitled. As soon as practicable after the determination of the amount of the net Fractional Warrant Share Proceeds, if any, to be paid in cash to each such Fractional Warrant Share Holder in lieu of its Fractional Warrant Share, the Transfer Agent shall make available such amounts, without interest, to each such Fractional Warrant Share Holder. ARTICLE 3 TRANSFER, EXCHANGE AND REPLACEMENT OF WARRANTS, LISTING SECTION 3.1 Ownership of Warrants. The Company and the Warrant Agent may deem and treat any Holder as the absolute owner for all purposes, notwithstanding any notation of ownership or other writing on the relevant Warrant Certificate made by anyone, and shall not be affected by any notice to the contrary until due presentation of such Warrant Certificate for registration and transfer as provided in this Article 3. SECTION 3.2 Registration and Countersignature. Warrant Certificates shall be countersigned manually or by facsimile and dated the date of countersignature by the Warrant Agent and shall not be valid for any purpose unless so countersigned. The Warrant Certificates shall be numbered and shall be registered in the Warrant Register. The countersignature of the Warrant Agent shall be that of a duly authorized employee of the Warrant Agent. SECTION 3.3 Registration of Transfers and Exchanges. (a) The Warrant Agent shall from time to time register the transfer of any outstanding Warrant Certificate in the Warrant Register, upon surrender of such Warrant Certificate, duly endorsed, and accompanied by a written instrument or instruments of transfer in a form satisfactory to the Warrant Agent, duly signed by the Holder or Holders thereof or by the duly appointed legal representative thereof or by a duly authorized attorney, such signature to be guaranteed by (i) a bank or trust company, (ii) a broker or dealer that is a member of the NASD or (iii) a member of a national securities exchange, and funds sufficient to pay and transfer taxes payable with respect to such transfer. Upon any such registration or transfer, a new Warrant Certificate shall be issued to the transferee. (b) Warrant Certificates may be exchanged at the option of the holder or holders thereof, when surrendered to the Warrant Agent at a Warrant Agent Office, or at the offices of any successor Warrant Agent as provided in Section 5.3 hereof, for another Warrant Certificate or other Warrant Certificates of like tenor and representing in the aggregate a like number of Warrants. (c) Notwithstanding paragraphs (a) and (b) above, the Warrant Agent shall not be required to transfer or exchange any Warrant Certificate from and after the 105th day preceding the scheduled Expiration Date provided that if, in the notice provided by the Company pursuant to Section 2.5, the Company shall not have elected to redeem the Warrants, then the Warrant Agent shall permit transfers or exchanges of Warrant Certificates from and after the mailing of the notice to Holders referred to in Section 2.5 but shall not be required to transfer or exchange any Warrant Certificate from and after the 15th day preceding the Expiration Date. SECTION 3.4 Cancellation of Warrants. If the Company shall purchase or otherwise acquire Warrants, the Company may deliver the Warrant Certificates representing such Warrants to the Warrant Agent to be canceled by it and retired. The Warrant Agent shall cancel all Warrant Certificates so surrendered. SECTION 3.5 Payments of Taxes. The Company will pay any documentary stamp taxes attributable to the initial issuance of Warrants and of Warrant Shares upon the exercise of Warrants; provided, that the Company shall not be required to pay any tax or taxes which may be payable in respect of any transfer involved in the issue of any Warrant Certificates or any certificates for Warrant Shares in a name other than the registered holder of Warrant Certificate surrendered upon the exercise of a Warrant, and the Company shall not be required to issue or deliver such certificates unless or until the person or persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. SECTION 3.6 Mutilated or Missing Warrant Certificates. (a) If (i) any mutilated Warrant Certificate is surrendered to the Warrant Agent or (ii) the Company and the Warrant Agent receive evidence to their satisfaction of the destruction, loss or theft of any Warrant Certificate, and there is delivered to the Company and the Warrant Agent such security or indemnity as may be reasonably required by them to hold each of them harmless with respect thereto, then, in the absence of notice to the Company or the Warrant Agent that such Warrant Certificate has been acquired by a bona fide purchaser, the Company shall execute and upon its written request the Warrant Agent shall countersign and deliver, in exchange for any such mutilated Warrant Certificate or in lieu of any such destroyed, lost or stolen Warrant Certificate, a new Warrant Certificate of like tenor and for a like aggregate number of Warrants. (b) Upon the issuance of any new Warrant Certificate under this Section 3.6 the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and other expenses (including the reasonable fees and expenses of the Warrant Agent and of counsel to the Company) in connection therewith. (c) Every new Warrant Certificate executed and delivered pursuant to this Section 3.6 in lieu of any destroyed, lost or stolen Warrant Certificate shall constitute an original contractual obligation of the Company, whether or not the destroyed, lost or stolen Warrant Certificate shall be at any time enforceable by anyone, and shall be entitled to the benefits of this Warrant Agreement equally and proportionately with any and all other Warrant Certificates duly executed and delivered hereunder. SECTION 3.7 Governmental Approvals and Stock Exchange Listing. The Company from time to time will use its best efforts (a) to obtain and keep effective any and all permits, consents and approvals of governmental agencies and authorities and to file such documents under federal and state securities acts and laws, which may be or become requisite in connection with the issuance, sale, transfer and delivery of the Warrant Certificates, the exercise of the Warrants and the issuance, sale, transfer and delivery of the Warrant Shares issued upon exercise of Warrants (including, without limitation, causing a registration statement under the Securities Act in respect of the Warrant Shares to be filed and declared effect but, subject to the Company's other contractual obligations, not including maintaining an effective registration statement for purposes of resale of Warrant Shares), provided, however, if any such permits, consents, approvals or documents are not so obtained or effective, the Company will immediately notify the Warrant Agent; (b) to have the Warrants listed on the NYSE or on the principal United States securities exchange on which the Common Stock is listed, if any, or quoted on NASDAQ if the Common Stock is so quoted; and (c) immediately upon the issuance of Warrant Shares upon exercise of Warrants, to have such Warrant Shares listed on the NYSE or on the principal United States securities exchange or exchanges on which the Common Stock is listed, if any, or quoted on NASDAQ if the Common Stock is so quoted. The Company shall cause the Warrants to be delisted on the NYSE or cease to be quoted, as the case may be, effective as of the Close of Business on the Expiration Date. Notwithstanding anything in this Agreement to the contrary, in no event shall a Holder be entitled to exercise a Warrant unless a registration statement filed under the Securities Act in respect of the Warrant Shares is then effective (unless in the opinion of counsel to the Company an exemption from the registration requirements is available under the Securities Act at the time of such exercise). SECTION 3.8 Transfer to Comply with the Securities Laws. Neither the Warrants nor any of the Warrant Shares, nor any interest in either, may be sold, assigned, pledged, hypothecated, encumbered or in any other manner transferred or disposed of, in whole or in part, except in compliance with applicable United States federal and state securities laws and the terms and conditions hereof and thereof. SECTION 3.9 Company Option to Repurchase Warrants. The Company and its subsidiaries shall have the option, in their sole discretion, at any time or from time to time, to purchase Warrants (i) in the public market, (ii) by tender or exchange offer available to all Holders at any price or (iii) in private transactions at a price not more than ten percent (10%) over the Market Price of the Warrants as of closing date of each such transaction respectively. Warrants acquired by the Company or its subsidiaries shall be canceled and shall not be available for reissuance or resale. ARTICLE 4 ANTI-DILUTION PROVISIONS SECTION 4.1 Adjustment of Exercise Price and Number of Shares Purchasable or Number of Warrants. The Exercise Price, the number of Warrant Shares purchasable upon the exercise of each Warrant and the number of Warrants outstanding are subject to adjustment from time to time upon the occurrence of the events enumerated in this Article 4. SECTION 4.2 Stock Dividends, Stock Splits, Combinations and Stock Reclassifications. If the Company shall (i) pay a dividend on its shares of capital stock (including Common Stock) in shares of Common Stock, (ii) subdivide its outstanding shares of Common Stock, (iii) combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock or (iv) issue any shares of its capital stock in a reclassification of the Common Stock (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing corporation), in each case, other than the Merger pursuant to the Merger Agreement, the number of Warrant Shares purchasable upon exercise of each Warrant immediately prior thereto shall be adjusted so that each Holder shall be entitled upon exercise to receive the kind and number of Warrant Shares or other securities of the Company which such Holder would have owned or have been entitled to receive after the happening of any of the events described above, had such Warrant been exercised immediately prior to the happening of such event or any record date with respect thereto. An adjustment made pursuant to this Section 4.2 shall become effective immediately after the effective date of such event retroactive to the record date, if any, for such event. SECTION 4.3 Rights, Options and Warrants. If the Company shall issue any rights, options or warrants to holders of its outstanding Common Stock (other than pursuant hereto, pursuant to stock option plans or similar plans approved by the Board of Directors of the Company or pursuant to the Merger Agreement), without payment of additional consideration by such holders, entitling them (for a period expiring within 45 days after the record date mentioned below) to subscribe for or purchase shares of Common Stock at a price per share that is lower than the Market Price per share of Common Stock at the record date mentioned below, the number of Warrant Shares thereafter purchasable upon the exercise of each Warrant shall be determined by multiplying the number of Warrant Shares theretofore purchasable upon exercise of each Warrant by a fraction, of which the numerator shall be (i) the number of shares of Common Stock outstanding on the record date for the issuance of such rights, options or warrants plus the number of additional shares of Common Stock offered for subscription or purchase, and of which the denominator shall be (ii) the number of shares of Common Stock outstanding on the record date for the issuance of such rights, options or warrants plus the number of shares which the aggregate offering price of the total number of shares of Common Stock so offered would purchase at the Market Price per share of Common Stock at such record date. Such adjustment shall be made whenever such rights, options or warrants are issued, and shall become effective immediately on the date of issuance retroactive to the record date for the determination of stockholders entitled to receive such rights, options or warrants. SECTION 4.4 Certain Distributions. If the Company shall distribute to all holders of its shares of Common Stock evidences of its indebtedness of assets (excluding cash dividends or distributions payable out of consolidated earnings or earned surplus and dividends or distributions referred to Section 4.2) or rights, options or warrants or convertible or exchangeable securities containing the right to subscribe for or purchase shares of Common Stock (excluding those referred to in Section 4.3), then in each case the number of Warrant Shares thereafter purchasable upon the exercise of each Warrant shall be determined by multiplying the number of Warrant Shares theretofore purchasable upon the exercise of each Warrant, by a fraction, of which the numerator shall be (i) the then current Market Price per share of Common Stock on the date of such distribution, and of which the denominator shall be (ii) the then current Market Price per share of Common Stock on the date of such distribution, less the then fair value (as determined in good faith by the Board of Directors of the Company, whose determination shall be conclusive and shall be evidenced by a resolution filed with the Warrant Agent) of the portion of the assets or evidences of indebtedness so distributed or of such subscription rights, options or warrants or convertible or exchangeable securities applicable to one share of Common Stock. Such adjustment shall be made whenever any such distribution is made, and shall become effective on the date of distribution retroactive to the record date for the determination of stockholders entitled to receive such distribution. SECTION 4.5 Capital Reorganizations and Stock Reclassifications. In the event of any capital reorganization or any reclassification of the Common Stock (except as provided in Section 4.2, 4.3, 4.4 or 4.6), any Holder of Warrants upon exercise thereof shall be entitled to receive, in lieu of the Common Stock to which such Holder would have become entitled upon exercise immediately prior to such reorganization or reclassification, the shares (of any class or classes) or other securities or property of the Company that such Holder would have been entitled to receive at the same aggregate Exercise Price upon such reorganization or reclassification if such Holder's Warrants had been exercised immediately prior thereto; and in any such case, appropriate provision (as determined in good faith by the Board of Directors of the Company, whose determination shall be conclusive and shall be evidenced by a resolution filed with the Warrant Agent) shall be made for the application of this Article 4 with respect to the rights and interests thereafter of the Holders (including the allocation of the adjusted Exercise Price between or among shares of classes of capital stock), to the end that this Article 4 (including the adjustments of the number of shares of Common Stock or other securities purchasable and the Exercise Price thereof) shall thereafter be reflected, as nearly as reasonably practicable, in all subsequent exercises of the Warrants for any shares or securities or other property thereafter deliverable upon the exercise of the Warrants. SECTION 4.6 Consolidations, Mergers, Sales and Conveyances. In case of any consolidation of the Company with or merger of the Company into another corporation or in case of any sale or conveyance to another corporation of the property of the Company as an entirety or substantially as an entirety, the Company or such successor or purchasing corporation, as the case may be, shall execute with the Warrant Agent an agreement that each Holder shall have the right thereafter upon payment of the Exercise Price in effect immediately prior to such action to purchase upon exercise of each Warrant the kind and amount of shares and other securities and property which such holder would have owned or have been entitled to receive after the happening of such consolidation, merger, sale or conveyance had such Warrant been exercised immediately prior to such action. The Company shall mail by first-class mail, postage prepaid, to each Holder, notice of the exception of any such agreement. Such agreement shall provide for adjustments, which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 4. The provisions of this Section 4.6 shall similarly apply to successive consolidations, mergers, sales or conveyances. The Warrant Agent shall be under no duty or responsibility to determine the correctness of any provisions contained in any such agreement relating either to the kind or amount of shares of stock or other securities or property receivable upon exercise of Warrants or with respect to the method employed and provided therein for any adjustments and shall be entitled to rely upon the provisions contained in any such agreement. SECTION 4.7 Adjustment Rules. (a) For the purposes of adjustments required by Section 4.2 and Section 4.3, the shares of Common Stock that the holder of any rights, options, warrants or convertible or exchangeable securities shall be entitled to subscribe for or purchase shall be deemed to be issued and outstanding as of the date of sale, issuance or distribution of such securities and the consideration, if any, received by the Company therefor shall be deemed to be the consideration received by the Company for such securities, plus the consideration or premiums stated in such securities to be paid for the shares of Common Stock covered thereby. (b) Except for adjustments required by Section 4.6, no adjustment in the number of Warrant Shares purchasable hereunder shall be required unless such adjustment would require an increase or decrease of at least one percent in the number of Warrant Shares purchasable upon the exercise of each Warrant; provided, however, that any adjustments which by reason of this Section 4.7(b) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations shall be made to the nearest cent and to the nearest one-hundredth of a share, as the case may be. (c) Whenever the number of Warrant Shares purchasable upon the exercise of each Warrant is adjusted as herein provided (whether or not the Company then or thereafter elects to issue additional Warrants in substitution for an adjustment in the number of Warrant Shares as provided in Section 4.7(h)), the Exercise Price payable upon exercise of each Warrant shall be adjusted by multiplying such Exercise Price immediately prior to such adjustment by a fraction, of which the numerator shall be the number of Warrant Shares purchasable upon the exercise of each Warrant immediately prior to such adjustment, and of which the denominator shall be the number of Warrant Shares so purchasable immediately thereafter, provided, however, that the Exercise Price shall not be reduced below par unless the Company has taken action pursuant to Section 2.8. (d) For the purpose of this Article 4, the term "shares of Common Stock" shall mean (i) the class of stock designated as the Common Stock of the Company at the date of this Agreement, or (ii) any other class of stock resulting from successive changes or reclassification of such shares consisting solely of changes in par value, or from par value to no par value, or from no par value to par value. If at any time, as a result of an adjustment made pursuant to Section 4.2 or Section 4.5 above, the holders of Warrants shall become entitled to purchase any shares of the Company other than shares of Common Stock, thereafter the number of such other shares so purchasable upon exercise of each Warrant and the Exercise Price with respect to such shares shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Warrant Shares contained in Section 4.2 through Section 4.5 and subsections (a), (b) and (c) of this Section 4.7, inclusive, above, and the provisions of Sections 3.2, 3.5, 3.7 and 4.9, with respect to the Warrant Shares, shall apply on like terms to any such other shares. (e) Except as provided in Sections 4.2, 4.3 and 4.4, no adjustment in respect of any dividends shall be made during the term of a Warrant or upon the exercise of a Warrant. (f) Irrespective of any adjustments in the Exercise Price or the number or kind of shares purchasable upon the exercise of the Warrants, Warrants theretofore or thereafter issued may continue to express the same price and number and kind of shares as are stated in the Warrants initially issuable pursuant to this Agreement. (g) Upon the expiration of any rights, options, warrants or conversion or exchange privileges, if any thereof shall not have been exercised, the Exercise Price and the number of Warrant Shares purchasable upon the exercise of each Warrant shall, upon such expiration, be readjusted and shall thereafter be such as it would have been had it been originally adjusted (or had the original adjustment not been required, as the case may be) as if (i) the only shares of Common Stock so issued were the shares of Common Stock, if any, actually issued or sold upon the exercise of such rights, options, warrants or conversions or exchange rights and (ii) such shares of Common Stock, if any, were issued or sold for the consideration actually received by the Company upon such exercise plus the aggregate consideration, if any, actually received by the Company for the issuance, sale or grant of all of such rights, options, warrants or conversion or exchange rights whether or not exercised; provided, that no such readjustment shall have the effect of increasing the Exercise Price or decreasing the number of shares by an amount in excess of the amount of the readjustment initially made in respect to the issuance, sale or grant of such rights, options, warrants or conversion or exchange rights. (h) The Company may elect, on or after the date of any adjustment required by Section 4.2 through Section 4.5, to adjust the number of Warrants in substitution for an adjustment in the number of Warrant Shares purchasable upon the exercise of a Warrant. Each of the Warrants outstanding after such adjustment of the number of Warrants shall be exercisable for the same number of Warrant Shares as immediately prior to such adjustment. Each Warrant held of record prior to such adjustment of the number of Warrants shall become that number of Warrants (calculated to the nearest hundredth) obtained by dividing the Exercise Price in effect prior to adjustment of the Exercise Price by the Exercise Price in effect after adjustment of the Exercise Price. The Company shall notify the Holders in the same manner as provided in Section 4.8, of its election to adjust the number of Warrants, indicating the record date for the adjustment, and, if known at the time, the amount of the adjustment to be made. This record date may be the date on which the Exercise Price is adjusted or any date thereafter. Upon each adjustment of the number of Warrants pursuant to this Section 4.7(h) the Company shall, as promptly as practicable, cause to be distributed to Holders as of such record date Warrant Certificates evidencing, subject to Sections 2.8 and 2.11, the additional Warrants to which such holders shall be entitled as a result of such adjustment, or, at the option of the Company, shall cause to be distributed to such holders of record in substitution and replacement for the Warrant Certificates held by such holders prior to the date of adjustment, and upon surrender thereof, if required by the Company, new Warrant Certificates evidencing all the Warrants to be issued, executed and registered in the manner specified in Sections 3.2 and 3.3 (and which may bear, at the option of the Company, the adjusted Exercise Price) and shall be registered in the names of the Holders on the record date specified in the notice. SECTION 4.8 Notice to Holders with Respect to Adjustments. Not more than 30 days following the record date or effective date, as the case may be, of any adjustment or readjustment pursuant to this Article 4, the Company shall forthwith file in the custody of its Secretary or an Assistant Secretary at its principal executive office and with the Warrant Agent, an officers' certificate showing the adjusted number of Warrant Shares purchasable upon exercise of the Warrants, the additional number of Warrants to be issued for each outstanding Warrant or the adjusted Exercise Price, as the case may be, determined as herein provided, setting forth in reasonable detail the facts requiring such adjustment and the manner of computing such adjustment. Each such officers' certificate shall be signed by the Chairman, President or Chief Financial Officer of the Company and by the Secretary or any Assistant Secretary of the Company. Each such officers' certificate shall be made available at the Warrant Agent Office all reasonable times for inspection by the Holder or any Holder of a Warrant and then upon written request of a Holder the Warrant Agent shall mail a copy of such certificate by first-class mail to such Holder. ARTICLE 5 WARRANT AGENT SECTION 5.1 Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company in accordance with the instructions hereinafter in this Agreement set forth; and the Warrant Agent hereby accepts such appointment, upon the terms and conditions hereinafter set forth. SECTION 5.2 Warrant Agent. (a) The Warrant Agent undertakes the duties and obligations imposed by this Agreement upon the following terms and conditions, by all of which the Company and the Holders, by their acceptance of the Warrants, shall be bound: (i) the statements contained herein and in the Warrant Certificates shall be taken as statements of the Company, and the Warrant Agent assumes no responsibility for the correctness of any of the same except such as describes the Warrant Agent or action taken or be taken by it. Except as herein otherwise provided, the Warrant Agent assumes no responsibility with respect to the execution, delivery or distribution of the Warrant Certificates. (ii) The Warrant Agent shall not be responsible for any failure of the Company to comply with any of the covenants contained in this Agreement or in the Warrant Certificates to be complied with by the Company nor shall it at any time be under any duty or responsibility to any Holder to make or cause to be made any adjustment in the Exercise Price or in the number of Warrant Shares issuable upon exercise of any Warrant (except as instructed by the Company), or to determine whether any facts exist which may require any such adjustments, or with respect to the nature or extent of or method employed in making any such adjustments when made. (iii) The Warrant Agent may consult at any time with counsel satisfactory to it (who may be counsel for the Company) and the Warrant Agent shall incur no liability or responsibility to the Company or any holder of any Warrant Certificate in respect of any action taken, suffered or omitted by it hereunder in good faith and in accordance with the opinion or the advice of such counsel. (iv) The Warrant Agent shall incur no liability or responsibility to the Company or to any Holder for any action taken in reliance on any notice, resolution, waiver, consent, order, certificate or other paper, document or instrument believed by it to be genuine and to have been signed, sent or presented by the proper party or parties. (v) The Company agrees promptly to pay the Warrant Agent the compensation to be agreed upon with the Company for all services rendered by the Warrant Agent and to reimburse the Warrant Agent for its reasonable out-of-pocket expenses (including attorneys' fees and expenses) incurred by the Warrant Agent without negligence, bad faith or breach of this Agreement on its part in connection with the services rendered by it hereunder. The Company also agrees to indemnify the Warrant Agent for, and to hold it harmless against, any loss, liability or expense (including reasonable attorneys' fees and expenses) incurred without negligence, bad faith or breach of this Agreement on the part of the Warrant Agent, arising out of or in connection with its acting as such Warrant Agent hereunder, as well as the reasonable costs and expenses of defending against any claim of liability in the premises. The obligations of the Company under this Section 5.2 shall survive the termination of this Agreement. (vi) The Warrant Agent shall be under no obligation to institute any action, suit or legal proceeding or to take any other action likely to involve expense unless the Company or one or more registered holders of Warrant Certificates shall furnish the Warrant Agent with reasonable security and indemnity for any costs or expenses which may be incurred. All rights of action under this Agreement or under any of the Warrants may be enforced by the Warrant Agent without possession of any of the Warrant Certificates or the production thereof at any trial or other proceeding relative thereto, and any such action, suit or proceeding instituted by the Warrant Agent shall be brought in its name as Warrant Agent, and any recovery or judgment shall be for the ratable benefit of the Holders, as their respective rights or interests may appear. (vii) The Warrant Agent, and any stockholder, director, officer or employee thereof, may buy, sell or deal in any of the Warrants or other securities of the Company or become pecuniarily interested in any transaction in which the Company may be interested, or contract with or lend money to the Company or otherwise act as fully and freely as though they were not the Warrant Agent under this Agreement, or a stockholder, director, officer or employee of the Warrant Agent, as the case may be. Nothing herein shall preclude the Warrant Agent from acting in any other capacity for the Company or for any other legal entity. (viii) The Warrant Agent shall act hereunder solely as agent for the Company, and its duties shall be determined solely by the provisions hereof. The Warrant Agent shall not be liable for anything which it may do or refrain from doing in connection with this Agreement except for its own negligence or bad faith. (ix) The Company agrees that it will perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further and other acts, instruments and assurances as may reasonably be required by the Warrant Agent for the carrying out or performing of the provisions of this Agreement. (x) The Warrant Agent shall not be under any responsibility in respect of the validity of this Agreement or the execution and delivery hereof (except the due execution hereof by the Warrant Agent) or in respect of the validity or execution of any Warrant Certificate (except its countersignature thereof), nor shall the Warrant Agent by any act hereunder be deemed to make any representation or warrant as to the authorization or reservation of the Warrant Shares to be issued pursuant to this Agreement or any Warrant Certificate or as to whether the Warrant Shares will when issued be validly issued, fully paid and nonassessable or as to the Exercise Price or the number of Warrant Shares issuable upon exercise of any Warrant. (xi) The Warrant Agent is hereby authorized and directed to accept instructions with respect to the performance of its duties hereunder from the Chairman of the Board, the Chief Executive Officer, the President, any Vice President, the Treasurer, the Secretary or an Assistant Secretary of the Company, and to apply to such officers for advice or instructions in connection with its duties, and shall not be liable for any action taken or suffered to be taken by it in good faith in accordance with instruction of any such officer or in good faith reliance upon any statement signed by any one of such officers of the Company with respect to any fact or matter (unless other evidence in respect thereof is herein specifically prescribed) which may be deemed to be conclusively proved and established by such signed statement. SECTION 5.3 Change of Warrant Agent. If the Warrant Agent shall resign (such resignation to become effective not earlier than 60 days after the giving of written notice thereof to the Company and the Holders) or shall become incapable of acting as Warrant Agent or if the Board of Directors of the Company shall by resolution remove the Warrant Agent (such removal to become effective not earlier than 30 days after the filing of a certified copy of such resolution with the Warrant Agent and the giving of written notice of such removal to the registered holders of Warrant Certificates), the Company shall appoint a successor to the Warrant Agent. If the Company shall fail to make such appointment within a period of 30 days after such removal or after it has been so notified in writing of such resignation or incapacity by the Warrant Agent, then any Holder may apply to any court of competent jurisdiction for the appointment of a successor to the Warrant Agent. Pending appointment of a successor to the Warrant Agent, either by the Company or by such a court, the duties of the Warrant Agent shall be carried out by the Company. Any successor Warrant Agent, whether appointed by the Company or by such a court, shall be a bank or trust company, in good standing, incorporated under the laws of any state or of the United States of America. As soon as practicable after appointment of the successor Warrant Agent, the Company shall cause written notice of the change in the Warrant Agent to be given to each of the Holders at such Holder's address appearing on the Warrant Register. After appointment, the successor Warrant Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Warrant Agent without further act or deed. The former Warrant Agent shall deliver and transfer to the successor Warrant Agent any property at the time held by it hereunder and execute and deliver, at the expense of the Company, any further assurance, conveyance, act or deed necessary for the purpose. Failure to give any notice provided for in this Section 5.3 or any defect therein, shall not affect the legality or validity of the removal of the Warrant Agent or the appointment of a successor Warrant Agent, as the case may be. SECTION 5.4 Merger, Consolidation or Change of Name of Warrant Agent. (a) Any corporation into which the Warrant Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Warrant Agent shall be a party, or any corporation succeeding to the shareholder services business of the Warrant Agent, shall be the successor to the Warrant Agent hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that such corporation would be eligible for appointment as a successor Warrant Agent under the provisions of Section 5.3. If at the time such successor to the Warrant Agent shall succeed under this Agreement, any of the Warrant Certificates shall have been countersigned but not delivered, any such successor to the Warrant Agent may adopt the countersignature of the original Warrant Agent, and if at that time any of the Warrant Certificates shall not have been countersigned, any successor to the Warrant Agent may countersign such Warrant Certificates either in the name of the predecessor Warrant Agent or in the name of the successor Warrant Agent; and in all such cases such Warrant Certificates shall have the full force provided in the Warrant Certificates and in this Agreement. (b) If at any time the name of the Warrant Agent shall be changed and at such time any of the Warrant Certificates shall have been countersigned but not delivered, the Warrant Agent whose name has changed may adopt the countersignature under its prior name; and if at that time any of the Warrant Certificates shall not have been countersigned, the Warrant Agent may countersign such Warrant Certificates either in its prior name or in its changed name; and in all such cases such Warrant Certificates shall have the full force provided in the Warrant Certificates and in this Agreement. ARTICLE 6 MISCELLANEOUS SECTION 6.1 Notices.

SECTION 6.3 Termination. This Agreement shall terminate immediately after (i) the Company has paid the Redemption Amount with respect to all Holders in the case of a Redemption or (ii) all Warrant Shares in respect of properly exercised Warrants have been issued in the case the Company does not elect to effect a Redemption pursuant to Section 2.7, provided, that the provisions of Section 5.2 shall survive such termination until such time that the obligations contemplated thereunder have been performed.

SECTION 6.6 Counterparts. This Agreement may be executed in any number of counterparts and each of such counterparts shall for all purposes be deemed to be an original, and such counterparts shall together constitute but one and the same instrument.

NEW YORK CITY TIME ON APRIL 28, 2000 CUSIP 5054OR 11 0 This Warrant Certificate certifies that or registered assigns, is the registered holder (the "Holder") of the number of warrants set forth above (each, a "Warrant") issued by Laboratory Corporation of America Holdings, a Delaware corporation (the "Company"), subject to the terms and conditions set forth herein and in the Warrant Agreement referred to on the reverse side hereof. Each Warrant entitles the Holder thereof to purchase from the Company one fully paid and nonassessable share (a "Warrant Share") of common stock, $0.01 par value (the "Common Stock"), of the Company at the initial exercise price per share of $22.00 (the "Exercise Price"), payable in lawful money of the United States of America, subject to adjustment as described below. The Warrants evidenced by this Certificate expire at 5:00 p.m. New York City Time (the "Close of Business") on April 28, 2000 (the "Expiration Date") unless such date is extended at the option of the Company as set forth in the Warrant Agreement referred to on the reverse side hereof. Subject to the terms and conditions set forth herein and in the Warrant Agreement referred to on the reverse side hereof, a Warrant may be exercised upon proper surrender of this Warrant Certificate and payment of the aggregate Exercise Price to American Stock Transfer & Trust Company (the "Warrant Agent") at 40 Wall Street, 46th Floor, New York, NY 10005 or such other of its offices as may be designated by the Warrant Agent (the "Warrant Agent Office"). The number of Warrants, the Exercise Price and the number of Warrant Shares purchasable upon exercise of a Warrant are subject to adjustment upon the occurrence of certain events as set forth in Article 4 of the Warrant Agreement referred to on the reverse side hereof Upon notice to the Warrant Agent in accordance with the Warrant Agreement, the Company may at its sole option elect to redeem all but not less than all of the Warrants on the Expiration Date by payment of an amount in cash in respect of each Warrant equal to the Redemption Amount (as defined in the Warrant Agreement).

A Warrant may only be exercised prior to the Close of Business on the Expiration Date and only if the Company shall not have elected to redeem the Warrants (provided that the Warrant Agent will accept surrenders of Warrant Certificates and payments of the Exercise Price in respect of Warrants to be exercised during the 45-day period preceding the Expiration Date, but such Warrants will not be deemed to have been exercised until the Expiration Date). As of the Close of Business on the Expiration Date, the Warrants will become wholly void and of no value. This Warrant Certificate shall be governed by and construed in accordance with the internal laws of the State of New York. REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS WARRANT CERTIFICATE SET FORTH ON THE REVERSE SIDE HEREOF.

Such request will specify the number of shares of or warrants constituting Registrable Securities proposed to be sold and will also specify the intended method of disposition thereof. Following the Investor's request, the Company will use its best efforts to effect, as expeditiously as possible, the registration under the Securities Act of the Registrable Securities which the Company has been so requested to register by the Investor so as to permit the disposition (in accordance with the intended methods thereof as aforesaid) of such Registrable Securities. (b) If the Investor so elects, the offering of such Registrable Securities pursuant to such Demand Registration shall be in the form of Public Offering.

SECTION 6.3. Additional Conditions to Demand Offerings. Notwithstanding the provisions of Sections 6.1 and 6.2, the Company's obligations pursuant to Section 6.1 shall be suspended if (a) the fulfillment of such obligations would require the Company to make a disclosure that would, in the reasonable good faith judgment of the Company's Board of Directors, be materially detrimental to the Company and premature, (b) the Company has filed a Registration Statement with respect to Equity Securities to be distributed in a Public Offering and it is advised by its lead or managing underwriter that an offering by the Investor of the Registrable Securities would materially adversely affect the distribution of such Equity Securities or (c) the fulfillment of such obligations would require the Company to prepare audited financial statements not required to be prepared for the Company to comply with its obligations under the Exchange Act as of any date not coincident with the last day of any fiscal year of the Company. Such obligations of the Company shall be reinstated (x) in the case of clause (a) above, upon the making of such disclosure by the Company (or, if earlier, when such disclosure would either no longer be necessary for the fulfillment of such obligations or no longer be detrimental), (y) in the case of clause (b) above, upon the conclusion of any period during which the Company would not, pursuant to the terms of its underwriting arrangements, be permitted to sell securities of the Company for its own account and (z) in the case of clause (c) above, as soon as it would no longer be necessary to prepare such financial statements to comply with the Exchange Act. SECTION 6.4. Piggyback Registration.

Upon the written request of the Investor made within ten days after the receipt of notice from the Company (which request shall specify the amount and types of Registrable Securities intended to be issued or disposed of), the Company will use its best efforts to effect the registration under the Securities Act of all such Registrable Securities which the Company has been so requested to register by such Investor, to the extent requisite to permit the disposition of such Registrable Securities to be so registered, provided that (i) if such registration involves a Public Offering, the Investor must sell its Registrable Securities to the underwriters on the same terms and conditions as apply to the Company and (ii) if, at any time after giving written notice of its intention to register any securities of the Company pursuant to this Section 6.4 and prior to the effective date of the Registration Statement filed in connection with such registration, the Company shall determine for any reason not to register such securities, the Company shall give written notice to the Investor and, thereupon, shall be relieved of its obligation to register any Registrable Securities in connection with such registration (without prejudice, however, to rights of the Investor under Section 6.1 hereof). No registration effected under this Section 6.4 shall relieve the Company of its obligations to effect any Demand Registration to the extent required by Section 6.1 hereof. SECTION 6.5.

SECTION 6.6. Filings; Registration Procedures. Whenever the Investor requests that any Registrable Securities be registered pursuant to Section 6.1 hereof, the Company will use its reasonable efforts to effect the registration of such Registrable Securities as promptly as is practicable, and in connection with any such request: (a) The Company will as expeditiously as possible prepare and file with the SEC a Registration Statement on any form for which the Company then qualifies and which counsel for the Company shall deem appropriate and available for the sale of the Registrable Securities to be registered thereunder in accordance with the intended method of distribution thereof. A registration will not count as a Demand Registration until a Registration Statement shall have become effective under the Securities Act and remained effective for at least 270 days (or such shorter period in which all Registrable Securities of the Investor included in such registration have actually been sold thereunder), provided that, if after any Registration Statement requested pursuant to Section 6.1 becomes effective, such Registration Statement is interfered with by any stop order, injunction or other order or requirement of the Commission or other governmental agency or court solely due to the actions or omissions to act of the Company, such registration shall not be considered a Demand Registration. (b) The Company will, if requested, prior to filing such Registration Statement or any amendment or supplement thereto, furnish to the Investor and each applicable managing underwriter, if any, copies thereof, and thereafter furnish to the Investor and each such underwriter such number of copies of such Registration Statement, amendment and supplement thereto (in each case including all exhibits thereto and documents incorporated by reference therein) and the prospectus included in such Registration Statement (including each preliminary prospectus) as the Investor or each such underwriter may reasonably request in order to facilitate the sale of the Registrable Securities. (c) The Company will use all reasonable efforts to cause the Registerable Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of the Company to enable the Investor to consummate the disposition of such Registrable Securities. (d) After the filing of the Registration Statement, the Company will (i) prepare and file with the SEC such amendments and post-effective amendments to the registration statement as may be necessary to keep such registration statement effective for a reasonable period not to exceed 270 days; cause the related prospectus to be supplemented by any required prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities Act, and (ii) comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement during the applicable period in accordance with the intended methods of disposition by the sellers thereof set forth in such registration statement or supplement to such prospectus and promptly notify the Investor of any stop order issued or, to the Company's knowledge, threatened to be issued by the SEC and take all reasonable actions required to prevent the entry of such stop order or to remove it if entered. (e) The Company will endeavor to qualify the Registrable Securities for offer and sale under such other securities or blue sky laws of such jurisdictions in the United States as the Investor reasonably requests, provided that the Company will not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 6.6(e), (ii) subject itself to taxation in any such jurisdiction or (iii) consent to general service of process in any such jurisdiction. (f) The Company will as promptly as is practicable notify the Investor, at any time when a prospectus relating to the sale of the Registrable Securities is required by law to be delivered in connection with sales by an underwriter or dealer, of the occurrence of any event requiring the preparation of a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and promptly make available to the Investor and to the underwriters, if any such supplement or amendment. The Investor agrees that, upon receipt of any notice from the Company of the occurrence of any event of the kind described in the preceding sentence, the Investor will forthwith discontinue the offer and sale of Registrable Securities pursuant to the Registration Statement covering such Registrable Securities until receipt by the Investor and the underwriters, if any, of the copies of such supplemented or amended prospectus and, if so directed by the Company, the Investor will deliver to the Company all copies, other than permanent file copies then in the Investor's possession, of the most recent prospectus covering such Registrable Securities at the time of receipt of such notice. In the event the Company shall give such notice, the Company shall extend the period during which such Registration Statement shall be maintained effective as provided in Section 6.6(a) hereof by the number of days during the period from and including the date of the giving of such notice to the date when the Company shall make available to the Investor such supplemented or amended prospectus. (g) The Company will enter into customary agreements (including an underwriting agreement in customary form) and take such other actions as are reasonably required in order to expedite or facilitate the sale of the Registrable Securities covered by a Registration Statement in accordance herewith. (h) The Company shall make available for inspection by the Investor, any underwriter participating in any disposition pursuant to such registration, and any attorney, accountant or other agent retained by the Investor or any such underwriter (collectively, the "Inspectors"), all financial and other records, pertinent corporate documents and properties of the Company (collectively, the "Records") as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause the officers, directors and employees of the Company to supply all information reasonably requested by any such Inspector in connection with such registration, provided that (i) records and information obtained hereunder shall be used by such Persons only to exercise their due diligence responsibility and (ii) records or information which the Company determines, in good faith, to be confidential shall not be disclosed by the Inspectors unless (x) the disclosure of such Records or information is necessary to avoid or correct a misstatement or omission in the Registration Statement or (y) the release of such Records or information is ordered pursuant to a subpoena or other order from a court or governmental authority of competent jurisdiction. The Investor shall use reasonable efforts, prior to any such disclosure, to inform the Company that such disclosure is necessary to avoid or correct a misstatement or omission in the Registration Statement. The Investor further agrees that it will, upon learning that disclosure of such Records or information is sought in a court or governmental authority, give notice to the Company and allow the Company, at the expense of the Company, to undertake appropriate action to prevent disclosure of the Records or information deemed confidential; the Investor agrees that information obtained by it as a result of such inspections shall be deemed confidential and shall not be used by it as the basis for any market transactions in the securities of the Company or its Affiliates unless and until such information is made generally available to the public. (i) The Company will furnish to the Investor and to each underwriter, if any, a signed counterpart, addressed to the Investor or such underwriter, if any, of (i) an opinion or opinions of counsel to the Company and (ii) a comfort letter or comfort letters from the Company's independent public accountants, each in customary form and covering such matters of the type customarily covered by opinions or comfort letters, as the case may be, as the Investor or the managing underwriter reasonably requests. (j) The Company will make generally available to its security holders, as soon as reasonably practicable, an earnings statement covering a period of 12 months, beginning within three months after the effective date of the Registration Statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act. (k) The Company will use its reasonable efforts to cause all such Registrable Securities to be listed on each securities exchange on which similar securities issued by the Company are then listed. (l) The Company may require the Investor promptly to furnish in writing to the Company such information regarding the Investor, the plan of distribution of the Registrable Securities and other information as the Company may from time to time reasonably request or as may be legally required in connection with such registration. SECTION 6.7. Registration Expenses. In connection with any Demand Registration or any Piggyback Registration, the Company shall pay the Registration Expenses. SECTION 6.8. Indemnification by the Company. The Company agrees to indemnify, to the fullest extent permitted by law, the Investor and directors, officers and controlling Persons of the Investor (within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act) against any and all losses, claims, damages, liabilities and expenses (including attorneys' fees) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement or prospectus (each as amended and or supplemented, if the Company shall have furnished any amendments or supplements thereto) or preliminary prospectus relating to the Registrable Securities, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading, provided that the Company shall not be required to indemnify the Investor or the officers, directors or controlling Persons of the Investor for any losses, claims, damages, liabilities or expenses resulting from any such untrue statement or omission if such untrue statement or omission is made in reliance on and conformity with any information with respect to the Investor furnished to the Company by the Investor expressly for use therein, and further provided that the foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of the Investor if a copy of the most current at the time of the delivery of the Registrable Securities prospectus was not provided to purchaser and such current prospectus would have cured the defect giving rise to such loss, claim, damage or liability. In connection with an underwritten offering, the Company will indemnify any underwriter thereof, the officers and directors of such underwriter, and each Person who controls such underwriter (within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act) to the same extent as provided above with respect to the indemnification of the Investor, provided that such underwriter agrees to indemnify the Company to the same extent as provided below with respect to the indemnification of the Company by the Investor. SECTION 6.9. Indemnification by the Investor. In connection with any registration in which the Investor is participating, the Investor will furnish to the Company in writing such information and affidavits with respect to the Investor as the Company reasonably requests for use in connection with any such registration, prospectus, or preliminary prospectus and agrees to indemnify the Company, its directors, its officers who sign the Registration Statement and each Person, if any, who controls the Company (within the meaning of either Section 15 of the Securities Act or of Section 20 of the Exchange Act) to the same extent as the foregoing indemnity from the Company to the Investor, but only with respect to information relating to the Investor furnished to the Company in writing by the Investor expressly for use in the Registration Statement, the prospectus, any amendment or supplement thereto, or any preliminary prospectus. SECTION 6.10. Conduct of Indemnification Proceedings. In case any proceeding (including any governmental investigation) shall be instituted involving any Person in respect of which indemnity may be sought pursuant to Section 6.8 or Section 6.9, such Person (the "Indemnified Party") shall promptly notify the Person against whom such indemnity may be sought (the "Indemnifying Party") in writing and the Indemnifying Party, upon request of the Indemnified Party, shall retain counsel reasonably satisfactory to the Indemnified Party to represent the Indemnified Party and any others the Indemnifying Party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any Indemnified Party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless (i) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the Indemnifying Party and the Indemnified Party and the Indemnified Party shall have been advised by counsel that representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the Indemnifying Party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) at any time for all such Indemnified Parties, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Indemnified Parties, such firm shall be designated in writing by the Indemnified Parties. The Indemnifying Party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Party agrees to indemnify the Indemnified Party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Party shall have requested an Indemnifying Party to reimburse the Indemnified Party for fees and expenses of counsel as contemplated by the third sentence of this Section 6.10, the Indemnifying Party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (A) such settlement is entered into more than 30 days after receipt by such Indemnifying Party of the aforesaid request and (B) such Indemnifying Party shall not have reimbursed the Indemnified Party in accordance with such request or reasonably objected in writing, on the basis of the standards set forth herein, to the propriety of such reimbursement prior to the date of such settlement. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such proceeding. SECTION 6.11. Contribution. (a) If the indemnification provided for in this Article from the Indemnifying Party is unavailable to an Indemnified Party hereunder in respect of any losses, claims, damages, liabilities or expenses referred to in this Article , then the Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages, liabilities or expenses (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, the Investor and the underwriters from the offering of the securities, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company, the Investor and the underwriters in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company, the Investor and the underwriters shall be deemed to be in the same respective proportions as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by each of the Company and the Investor Group and the total underwriting discounts and commissions received by the underwriters, in each case as set forth in the table on the cover of the prospectus, bear to the aggregate public offering price of the securities. The relative fault of the Company, the Investor and the underwriters shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, each such party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 6.10, any legal or other fees or expenses reasonably incurred by such party in connection with any investigation or proceeding. (b) The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 6.11 were determined by pro rata allocation (even if the underwriters were treated as one entity for such purpose or by any other method of allocation which does not take into account the equitable considerations referred to in the immediately preceding Section 6.11(a). Notwithstanding the provisions of this Article , no underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Equity Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and the Investor shall not be required to contribute any amount in excess of the amount by which the net proceeds of the offering (before deducting expenses) received by the Investor Group exceeds the amount of any damages which the Investor has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. (c) If indemnification is available under this Article , the Indemnifying Party shall indemnify each Indemnified Party to the full extent provided in Sections 6.8 and 6.9 without regard to the relative fault of said Indemnifying Party or Indemnified Party or any other equitable consideration provided for in this Section 6.11. ARTICLE 7 FURNISHING OF INFORMATION SECTION 7.1. Furnishing of Information. (a) The Company will furnish or make available to the Investor any documents filed by the Company pursuant to each of Section 13, 14 and 15(d) of the Exchange Act (or successor provisions) and all annual, quarterly or other reports furnished to the Company's public security holders and all such other information concerning the Company and its Subsidiaries as the Investor may reasonably request. (b) From and after the Effectiveness of this Agreement, the Company shall furnish to the Investor: (i) within 60 days after the end of each fiscal year, its consolidated balance sheet and related statements of income and changes in financial position, showing the financial condition of the Company and its consolidated Subsidiaries as of the close of such fiscal year and the results of its operations and the operations of such Subsidiaries during such year, all audited by the Company's independent public accountants of recognized international standing and accompanied by an opinion of such accountants (which shall not be qualified in any material respect) to the effect that such consolidated financial statements fairly present the financial condition and results of operations of the Company on a consolidated basis in accordance with GAAP consistently applied; and (ii) within 30 days after the end of each of the first three fiscal quarters of each fiscal year, its consolidated balance sheet and related statements of income and changes in financial position, showing the financial condition of the Company and its consolidated Subsidiaries as of the close of such fiscal quarter and the results of its operations and the operations of such Subsidiaries during such fiscal quarter and the then elapsed portion of the fiscal year, all certified by one of the senior financial officers as fairly presenting the financial condition and results of operations of the Company on a consolidated basis in accordance with GAAP consistently applied, subject to normal year-end audit adjustments. (c) At the request of the Investor, at such time as the Investor is required to include the financial results of the Company in the Investor's financial statements, the Company shall cooperate with and assist the Investor in the translation of the financial statements referred to in Subsection (a) above in order to conform such financial statements to international accounting standards. (d) The Company shall deliver to the Investor, within a reasonable period of time after receipt of a request from the Investor, the statement required by Treasury Department Regulation Section 1.897-2(h)(1) (relating to the Company's and each of its Subsidiaries' status as a United States Real Property Holding Corporation) without regard to whether the Company's Equity Securities are publicly traded at the time such statement is requested. ARTICLE 8 COVENANTS SECTION 8.1. Rule 144 and Rule 144A. (a) The Company covenants that it will file the reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder, and it will take such further action as the Investor may reasonably request, all to the extent required from time to time to enable the Investor to sell Shares without registration under the Securities Act within the limitation of the exemptions provided by (i) Rule 144 under the Securities Act, as such Rule may be amended from time to time, or (ii) any similar rule or regulation hereafter adopted by the SEC. Upon the request of the Investor, the Company will deliver to the Investor a written statement as to whether it has complied with such reporting requirements. (b) If the Investor desires to transfer any of its securities of the Company pursuant to Rule 144A, the Company will promptly, upon request by the Investor, use its best efforts to facilitate the consummation of such Rule 144A transaction in accordance with the requirements of such Rule and with such request and shall take all necessary or appropriate actions in connection therewith, including but not limited to (i) preparing of an offering memorandum with respect to such transaction containing information customarily included in connection with Rule 144A transactions of the type contemplated by the request, (ii) taking the actions, to the extent requested by the Investor, referred to in Section 6.6(e), (h) and (i) and (iii) conducting "road show" presentations as reasonably requested by such Investor. Notwithstanding the previous sentence, if the Investor Group Interest shall be less than 30%, the Company will only be required to facilitate the consummation of such Rule 144A transaction as follows: (x) if the Investor Group Interest shall be less than 30% but more than 20%, no more than three other Rule 144A transactions shall have been effected after the date on which the Investor Group Interest was reduced to less than 30%, (y) if the Investor Group Interest shall be less than 20% but more than 10%, no more than two other Rule 144A transactions shall have been effected after the date on which the Investor Group Interest was reduced to less than 20% and (z) if the Investor Group Interest shall be less than 10%, no more than one other Rule 144A transaction shall have been effected after the date on which the Investor Group Interest was reduced to less than 10%. The Company shall pay all expenses in connection with any Rule 144A transaction pursuant hereto to the same extent the Company would be obligated to pay Registration Expenses in connection with a Demand or Piggyback Registration pursuant to Section 6.7. SECTION 8.2. No Inconsistent Agreements. The Company is not bound by any agreement and will not hereafter enter into any agreement, with respect to its securities which conflicts or is inconsistent with the rights granted to the Investor, the Investor Group or Investor Directors.
