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.

(b)Except as otherwise identified in the NHL Disclosure Schedule: (i) no NHL Employee Plan constitutes a "multiemployer plan", as defined in Section 3(37) of ERISA (a "Multiemployer Plan"), and no NHL Employee Plan is maintained in connection with any trust described in Section 501(c)(9) of the Code; (ii) no NHL Employee Plans are subject to Title IV of ERISA (the "NHL Retirement Plans"); (iii) as of December 31, 1993, the fair market value of the assets of each NHL Retirement Plan (excluding for these purposes any accrued but unpaid contributions) exceeded the accumulated benefit obligation, as determined in accordance with GAAP, under such NHL Retirement Plan; (iv) no "accumulated funding deficiency", as defined in Section 412 of the Code, has been incurred with respect to any NHL Retirement Plan, whether or not waived; (v) no "reportable event", within the meaning of Section 4043 of ERISA, and no event described in Section 4041, 4042, 4062 or 4063 of ERISA has occurred in connection with any NHL Employee Plan, other than a "reportable event" that will not have an NHL Material Adverse Effect; (vi) no condition exists and no event has occurred that could constitute grounds for termination of any NHL Retirement Plan or, with respect to any NHL Employee Plan which is a Multiemployer Plan, presents a material risk of a complete or partial withdrawal under Title IV of ERISA; (vii) neither NHL nor any of its ERISA Affiliates has incurred any material liability under Title IV of ERISA arising in connection with the termination of, or complete or partial withdrawal from, any plan covered or previously covered by Title IV of ERISA; (viii) if a "complete withdrawal" by NHL and all of its ERISA Affiliates were to occur as of the Effective Time with respect to all NHL Employee Plans which are Multiemployer Plans, neither NHL nor any ERISA Affiliate would incur any withdrawal liability under Title IV of ERISA; (ix) nothing done or omitted to be done and no transaction or holding of any asset under or in connection with any NHL Employee Plan has made or will make NHL or any of its Subsidiaries, any officer or director of NHL or any of its Subsidiaries subject to any liability under Title I of ERISA or liable for any Tax pursuant to Section 4975 of the Code that could have an NHL Material Adverse Effect; and (x) neither NHL nor any of its ERISA Affiliates (A) has engaged in a transaction described in Section 4069 of ERISA that could subject NHL to material liability at any time after the date hereof or (B) has acted in a manner that could, or failed to act so as to, result in fines, penalties, taxes or related charges under (x) Section 502(c), (i) or (1) or ERISA, (y) Section 4071 of ERISA or (z) Chapter 43 of the Code, which penalties, taxes or related charges, individually or in the aggregate, would constitute a liability in a material amount. (c)Each NHL Employee Plan which is intended to be qualified under Section 401(a) of the Code has received a favorable IRS determination letter to such effect and NHL knows of no event or circumstance occurring or existing since the date of such letter that would adversely affect such NHL Employee Plan's qualified status. NHL has furnished or made available upon request to HLR and RBL copies of the most recent IRS determination letters with respect to each such Plan. Each NHL Employee Plan has been maintained in substantial compliance with its terms and with the requirements prescribed by any and all statutes, orders, rules and regulations, including but not limited to ERISA and the Code, which are applicable to such Plan. There are no investigations by any governmental agency, termination proceedings or other claims (except claims for benefits payable in the normal operation of the NHL Employee Plans), suits or proceedings against or involving any NHL Employee Plan or asserting any rights to or claims for benefits under any NHL Employee Plan that could give rise to any material liability, and there are not any facts that could give rise to any material liability in the event of any such investigation, claim, suit or proceeding. (d)There is no contract, agreement, plan or arrangement covering any employee or former employee of NHL or any ERISA Affiliate that, individually or collectively, could give rise to the payment of any amount that would not be deductible pursuant to the terms of Section 280G of the Code. No employee of NHL or any of its Subsidiaries will be entitled to any additional benefits or any acceleration of the time of payment or vesting of any NHL benefits under any NHL Benefit Arrangements (as defined below in Section3.14(e)) as a result of the transactions contemplated by this Agreement. (e)NHL has furnished or made available upon request to RBL copies or descriptions of each employment, severance or other similar contract, arrangement or policy providing for annual compensation in excess of $200,000 and each plan or arrangement (written or oral) providing for insurance coverage (including any self-insured arrangements), workers' compensation, disability benefits, supplemental unemployment benefits, vacation benefits, retirement benefits or for deferred compensation, profit-sharing, bonuses, stock options, stock appreciation or other forms of incentive compensation or post-retirement insurance, compensation or benefits which (i) is not an Employee Plan, (ii) is entered into, maintained or contributed to, as the case may be, by NHL or any of its Subsidiaries and (iii) covers any employee or former employee of NHL or any of its Subsidiaries, to the extent existing on the date hereof. The above arrangements (whether or not existing as of the date hereof) are referred to collectively herein as the "NHL Benefit Arrangements"). Each NHL Benefit Arrangement has been maintained in substantial compliance with its terms and with the requirements prescribed by any and all statutes, orders, rules and regulations that are applicable to such NHL Benefit Arrangement. (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. As of the date of this Agreement, to the knowledge of NHL, neither NHL nor its Subsidiaries, nor their respective representatives or employees, has committed any unfair labor practices in connection with the operation of the respective businesses of NHL or its Subsidiaries, and there is no pending or threatened in writing charge or complaint against NHL or its Subsidiaries by the National Labor Relations Board (the "NLRB") or any comparable state agency, except where such unfair labor practice, charge or complaint would not have an NHL Material Adverse Effect. 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. SECTION 3.17. Other Information. NHL's projections and forward-looking information furnished by NHL to HLR were prepared in good faith and represent NHL's best estimate as of the date hereof as to the subject matter thereof; provided that NHL makes no representation or warranty as to the completeness or accuracy of the projections or forward-looking information furnished by NHL to HLR. SECTION 3.18. Environmental Matters. Except as set forth in the SEC Documents: (a) (i) no notice, notification, notice of violation, demand, request for information, investigation (whether civil or criminal), citation, summons, complaint, order or other similar document has been received by, or, to the knowledge of NHL or any of its Subsidiaries, is pending or threatened by any Person against, NHL or any of its Subsidiaries, nor has any material penalty been assessed against NHL or any of its Subsidiaries in either case with respect to any (A) alleged violation of any Environmental Law or liability thereunder, (B) alleged failure to have any permit, certificate, license, approval, registration or authorization required under any Environmental Law, (C) generation, treatment, storage, recycling, transportation or disposal of any Hazardous Substance or (D) Release of any Hazardous Substance; (ii) no Hazardous Substance has been Released or is present at any property now owned, leased or operated by NHL or any of its Subsidiaries nor, to the knowledge of NHL, has any Hazardous Substance been Released at any property formerly owned, leased or operated by NHL, which Release or presence, individually or in the aggregate, could reasonably be expected to result in an NHL Material Adverse Effect; (iii) there are no NHL Environmental Liabilities that have had or may reasonably be expected to have, individually or in the aggregate, an NHL Material Adverse Effect; and (iv) there are no circumstances relating to the disposal of Hazardous Substances from any properties at the time they were owned, leased or operated by NHL that could give rise to liabilities under Environmental Laws which could reasonably be expected to result in, individually or in the aggregate, an NHL Material Adverse Effect. (b) There has been no environmental investigation, study, audit, test, review or other analysis conducted since 1989 of which NHL has knowledge in relation to the current or prior business of NHL or any property or facility now or previously owned, leased or operated by NHL or any of its Subsidiaries the contents of which could reasonably be expected to result in an NHL Material Adverse Effect. (c) Neither NHL nor any of its Subsidiaries owns or leases any real property or an industrial facility, or conducts any operations, in New Jersey or Connecticut. (d) For purposes of this Section 3.18, the following terms shall have the meanings set forth below: (i) "NHL" and "Subsidiary" shall include any entity which is, in whole or in part, a predecessor of NHL or any of its Subsidiaries. (ii) "NHL Environmental Liabilities" means any and all liabilities of or relating to NHL and any of its Subsidiaries, whether vested or unvested, contingent or fixed, actual or potential, known or unknown, which (A) arise under or relate to matters covered by Environmental Laws and (B) arose from actions occurring or conditions existing on or prior to the Effective Time. (e) For purposes of this Section 318 and Section 416, the following terms shall have the meanings set forth below: (i) "Environmental Laws" means any and all federal, state, local and foreign statutes, laws, judicial decisions, regulations, ordinances, rules, judgments, orders, decrees, codes, injunctions, permits, licenses, agreements and governmental restrictions (whether now or hereinafter in effect), relating to human health, the environment or to emissions, discharges, Releases or threatened Releases of Hazardous Substances or wastes into the environment, including, without limitation, ambient air, surface water, ground water or land, or otherwise relating to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Substances or wastes or the investigation, clean-up, remediation or monitoring thereof. (ii) "Hazardous Substances" means any toxic, radioactive, caustic, corrosive, infectious, mutagenic, carcinogenic or otherwise hazardous waste, material or substance, including petroleum, its derivatives, by-products and other hydrocarbons, or any substance having any constituent elements displaying any of the foregoing characteristics, including, without limitation, any substance which meets the definition of "hazardous substance" contained in 42 U.S.C. Section 9601(14). (iii) "Release" means any discharge, emission or release, including a Release as defined in the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended ("CERCLA") at 42 U.S.C.

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. ARTICLE 4 REPRESENTATIONS AND WARRANTIES OF HLR AND RBL HLR and RBL represent and warrant to NHL that, except as set forth on the disclosure schedule delivered by RBL to NHL prior to the execution of this Agreement (the "RBL Disclosure Schedule"): SECTION 4.1.

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 4.4. Non-Contravention.

SECTION 4.5. Capitalization of RBL. The authorized capital stock of RBL consists of 1000 shares of common stock, no par value per share, 100 shares of which are issued and outstanding and no shares of which are held in RBL's treasury.

There are no partnerships or joint venture arrangements or other business entities in which RBL or any Subsidiary of RBL owns an equity interest that is material to the business of RBL and its Subsidiaries, taken as a whole. (b)All of the outstanding capital stock of each Subsidiary of RBL is owned by RBL, directly or indirectly, free and clear of any Lien and free of any other limitation or restriction (including any restriction on the right to vote, sell or otherwise dispose of such capital stock) other than any such limitations or restrictions imposed by statutes or regulations of general applicability.

There are no investigations by any governmental agency, termination proceedings or other claims (except claims for benefits payable in the normal operation of the RBL Employee Plans), suits or proceedings against or involving any RBL Employee Plan or asserting any rights to or claims for benefits under any RBL Employee Plan that could give rise to any material liability, and there are not any facts that could give rise to any material liability in the event of any such investigation, claim, suit or proceeding.

(g) Except as disclosed in the RBL Disclosure Schedule, there has been no amendment to, written interpretation or announcement (whether or not written) by RBL or any of its ERISA Affiliates relating to, or change in employee participation or coverage under, any RBL Employee Plan or RBL Benefit Arrangement which would increase materially the expense of maintaining such RBL Employee Plan or RBL Benefit Arrangement above the level of the expense incurred in respect thereof for the fiscal year ended on the RBL Balance Sheet Date (other than those that would not result in the representation and warranty set forth in Section 4.9(i) becoming untrue as of the Effective Time). (h) Neither RBL 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 RBL or its Subsidiaries and no collective bargaining agreement is being negotiated by RBL or any of its Subsidiaries.

(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.
