FIRST UNION SECURITIES, INC.

c/o Banc of America Securities LLC
9 West 57th Street, 47th Floor
New York, NY  10019

Ladies and Gentlemen:

            Introductory. Pursuant to the terms of a Note Purchase Agreement,
dated October 17, 2001, among InSight Health Services Acquisition Corp., a
Delaware corporation, InSight Health Services Corp., a Delaware corporation (the
"Company"), InSight Health Services Holdings Corp., a Delaware corporation
("Holdings"), the Subsidiary Guarantors (as defined herein), Banc of America
Bridge LLC and Banc of America Securities LLC, (the "Note Purchase Agreement"),
the Company is (i) issuing to Banc of America Securities LLC and First Union
Securities, Inc. (collectively, the "Initial Purchasers"), acting severally and
not jointly, the respective amounts set forth in Schedule D of $200,000,000
aggregate principal amount of the Company's 9-7/8% Senior Subordinated Notes Due
2011 (the "Initial Notes") in exchange for $200,000,000 principal amount of the
Company's 12-1/8% Senior Subordinated Notes due 2011 (the "Existing Notes") and
(ii) issuing and selling to the Initial Purchasers, acting severally and not
jointly, the respective amounts set forth in Schedule D of an additional
$25,000,000 aggregate principal amount of the Company's 9-7/8% Senior
Subordinated Notes due 2011 (the "Additional Notes" and, together with the
Initial Notes, the "Notes). Terms used herein and not otherwise defined herein
shall have the respective meanings assigned to them in the Note Purchase
Agreement.

            The Notes will be issued pursuant to an indenture, dated as of
October 30, 2001 (the "Indenture"), among the Company, the Guarantors (as
defined below) and State Street Bank and Trust Company N.A., as trustee (the
"Trustee"). Notes issued in book-entry form will be issued in the name of Cede &
Co., as nominee of The Depository Trust Company (the "Depositary") pursuant to a
letter of representations, to be dated as of the Closing Date (as defined in
Section 2), to be entered into in connection with the issuance of the Securities
(the "DTC Letter of Representations") among the Company, the Trustee and the
Depositary.

            The payment of principal of, premium and Liquidated Damages (as
defined in the Indenture), if any, and interest on the Notes and the Exchange
Notes (as defined below) will,
<PAGE>
upon issuance of the Notes, become fully and unconditionally guaranteed on a
senior subordinated and unsecured basis, jointly and severally by (i) Holdings,
(ii) each of the Company's directly and indirectly wholly-owned subsidiaries
listed in Schedule A attached hereto, and (iii) any wholly-owned or other
subsidiary of the Company formed or acquired after the Closing Date that
executes an additional guarantee in accordance with the terms of the Indenture,
and respective successors and assigns of Holdings and the subsidiaries of the
Company referred to in (ii) and (iii) above (collectively, the "Guarantors," and
the subsidiaries referred to in (ii) and (iii) above, the "Subsidiary
Guarantors"), pursuant to their guarantees (the "Guarantees"). The Notes and the
Guarantees attached thereto are herein collectively referred to as the
"Securities," and the Exchange Notes and the Guarantees attached thereto are
herein collectively referred to as the "Exchange Securities."

            The holders of the Notes will be entitled to the benefits of a
remarketed notes registration rights agreement, to be dated as of the Closing
Date (the "Registration Rights Agreement"), among the Company, the Guarantors
and the Initial Purchasers, substantially in the form of Exhibit E attached to
the Note Purchase Agreement, pursuant to which the Company and the Guarantors
agree to file, within 120 days of the Closing Date, a registration statement
with the Securities and Exchange Commission (the "Commission") registering the
Exchange Securities under the Securities Act of 1933, as amended (the
"Securities Act," which term, as used herein, includes the rules and regulations
of the Commission promulgated thereunder).

            The Company understands that the Initial Purchasers propose to make
an offering of the Securities on the terms and in the manner set forth herein
and in the Offering Memorandum (as defined below) and agrees that the Initial
Purchasers may sell, subject to the conditions set forth herein, all or a
portion of the Securities to purchasers (the "Subsequent Purchasers") at any
time after the date of this Agreement. The Securities are to be offered and sold
to or through the Initial Purchasers without being registered with the
Commission under the Securities Act, in reliance upon exemptions therefrom. The
terms of the Securities and the Indenture will require that investors that
acquire Securities expressly agree that Securities may only be resold or
otherwise transferred, after the date hereof, if such Securities are registered
for sale under the Securities Act or if an exemption from the registration
requirements of the Securities Act is available (including the exemptions
afforded by Rule 144A under the Securities Act ("Rule 144A") or Regulation S
under the Securities Act ("Regulation S")).

            The Company has prepared and delivered to the Initial Purchasers
copies of a preliminary offering memorandum, dated October 19, 2001 (the
"Preliminary Offering Memorandum"), and has prepared and will deliver to the
Initial Purchasers, copies of the Offering Memorandum (defined below),
describing the terms of the Securities, each for use by the Initial Purchasers
in connection with their solicitation of offers to purchase the Securities. As
used herein, the "Offering Memorandum" shall mean, with respect to any date or
time referred to in this Agreement, the offering memorandum, dated October 25,
2001, including amendments or supplements thereto, any exhibits thereto and the
Incorporated Documents (as defined in Section 1 below), in the most recent form
that has been prepared and delivered by the Company to the Initial Purchasers in
connection with their solicitation of offers to purchase Securities. Further,
any reference to the Preliminary Offering Memorandum or the Offering Memorandum
shall be deemed to refer to and include any Additional Issuer Information (as
defined in Section 3) furnished by the Company prior to the completion of the
distribution of the Securities.

                                       2
<PAGE>
            All references in this Agreement to financial statements and other
information which is "contained," "included" or "stated" in the Offering
Memorandum (or other references of like import) shall be deemed to mean and
include all such financial statements and schedules and other information which
are incorporated by reference in the Offering Memorandum; all references in this
Agreement to amendments or supplements to the Offering Memorandum shall be
deemed to mean and include the filing of any document under the Securities
Exchange Act of 1934 (as amended, the "Exchange Act," which term, as used
herein, includes the rules and regulations of the Commission promulgated
thereunder) which is incorporated or deemed to be incorporated by reference in
the Offering Memorandum; and all references in this Agreement to the Transaction
Documents shall be deemed to mean and include this Purchase Agreement, the
Registration Rights Agreement, the Indenture, the Securities and the DTC Letter
of Representations. References herein to "Subsidiaries" shall mean each
corporation, partnership, joint venture or other entity in which (i) the Company
owns, directly or indirectly, 50% or more of the outstanding voting securities
or equity interests or (ii) the Company or any Subsidiary is the sole general
partner or the sole managing member.

            Each of the Company and the Guarantors hereby confirms its
respective agreement with the Initial Purchasers as follows:

            Section 1. Representations and Warranties. The Company and each of
the Guarantors hereby jointly and severally represent, warrant and covenant to
each Initial Purchaser as follows:

            (a) No Registration Required. Subject to compliance by the Initial
      Purchasers with the representations and warranties set forth in Section
      2(e) hereof and with the procedures set forth in Section 7 hereof, it is
      not necessary in connection with the issuance and sale of the Securities
      to the Initial Purchasers and the offer, sale and delivery of the
      Securities to each Subsequent Purchaser in the manner contemplated by this
      Agreement and the Offering Memorandum to register the Securities under the
      Securities Act or, until such time as the Exchange Securities are issued
      pursuant to an effective registration statement, to qualify the Indenture
      under the Trust Indenture Act of 1939 (the "Trust Indenture Act," which
      term, as used herein, includes the rules and regulations of the Commission
      promulgated thereunder).

            (b) No Integration of Offerings or General Solicitation. None of the
      Company or any Guarantor has, directly or indirectly, solicited any offer
      to buy or offered to sell, and none of them will, directly or indirectly,
      solicit any offer to buy or offer to sell, in the United States or to any
      United States citizen or resident, any security which is or would be
      integrated with the sale of the Securities in a manner that would require
      the Securities to be registered under the Securities Act. None of the
      Company, the Guarantors, their respective affiliates (as such term is
      defined in Rule 501(b) under the Securities Act (each, an "Affiliate")) or
      any person acting on their behalf (other than the Initial Purchasers, as
      to whom none of the Company or any Guarantor makes any representation or
      warranty) has engaged or will engage, in connection with the offering of
      the Securities, in any form of general solicitation or general advertising
      within the meaning of Rule 502(c) under the Securities Act. With respect
      to those Securities sold in reliance upon Regulation S, (i) none of the
      Company, the Guarantors, their Affiliates or

                                       3
<PAGE>
      any person acting on their behalf (other than the Initial Purchasers, as
      to whom none of the Company or any Guarantor makes any representation or
      warranty) has engaged or will engage in any directed selling efforts
      within the meaning of Regulation S and (ii) each of the Company, the
      Guarantors and their Affiliates and any person acting on their behalf
      (other than the Initial Purchasers, as to whom none of the Company or any
      Guarantor makes any representation or warranty) has complied and will
      comply with the offering restrictions set forth in Regulation S.

            (c) Eligibility for Resale Under Rule 144A. The Securities are
      eligible for resale pursuant to Rule 144A and will not be, at the Closing
      Date, of the same class as securities listed on a national securities
      exchange registered under Section 6 of the Securities Exchange Act of
      1934, as amended (the "Exchange Act," which term, as used herein, includes
      the rules and regulations of the Commission promulgated thereunder) or
      quoted in a U.S. automated interdealer quotation system.

            (d) The Offering Memorandum. The Offering Memorandum does not, and
      at the Closing Date will not, include an untrue statement of a material
      fact or omit to state a material fact necessary in order to make the
      statements therein, in the light of the circumstances under which they
      were made, not misleading; provided that this representation, warranty and
      agreement shall not apply to statements in or omissions from the Offering
      Memorandum made in reliance upon and in conformity with information
      furnished to the Company in writing by the Initial Purchasers expressly
      for use in the Offering Memorandum. Each of the Preliminary Offering
      Memorandum and the Offering Memorandum, as of its respective date,
      contains all the information specified in, and meeting the requirements of
      Rule 144A(d)(4). None of the Company or any Guarantor has distributed and
      none of them will distribute, prior to the later of the Closing Date and
      the completion of the Initial Purchasers' distribution of the Securities,
      any offering material in connection with the offering and sale of the
      Securities other than the Preliminary Offering Memorandum, the Offering
      Memorandum or as agreed upon by the Initial Purchasers.

            (e) Incorporated Documents. The Offering Memorandum as delivered
      from time to time shall incorporate by reference the Annual Report of the
      Company on Form 10-K for the fiscal year ended June 30, 2001 filed with
      the Commission on September 14, 2001 (the "Annual Report"), each Quarterly
      Report of the Company on Form 10-Q and each Current Report of the Company
      on Form 8-K (and any amendment(s) thereto) filed with the Commission
      between the date hereof and the Closing Date. The documents incorporated
      or deemed to be incorporated by reference in the Offering Memorandum, at
      the time they were, or hereafter are, filed with the Commission
      (collectively, the "Incorporated Documents") complied and will comply in
      all material respects with the requirements of the Exchange Act.

            (f) The Purchase Agreement. This Agreement has been duly authorized,
      executed and delivered by each of the Company and the Guarantors.

            (g) The Registration Rights Agreement. At the Closing Date, the
      Registration Rights Agreement will have been duly authorized, executed and
      delivered by, and

                                       4
<PAGE>
      (assuming the due authorization, execution and delivery thereof by the
      other parties thereto) will be a valid and binding agreement of, the
      Company and each Guarantor, enforceable in accordance with its terms,
      except as rights to indemnification and contribution thereunder may be
      limited by applicable law and except as the enforcement thereof may be
      limited by bankruptcy, insolvency, fraudulent conveyance, reorganization,
      moratorium or other similar laws relating to or affecting the rights and
      remedies of creditors or by general equitable principles (whether
      considered in a proceeding at law or in equity). Pursuant to the
      Registration Rights Agreement, the Company and each Guarantor will agree
      to file with the Commission, under the circumstances set forth therein,
      (i) a registration statement under the Securities Act relating to another
      series of debt securities of the Company with terms substantially
      identical to the Notes (the "Exchange Notes") to be offered in exchange
      for the Notes (the "Exchange Offer") and (ii) to the extent required by
      the Registration Rights Agreement, a shelf registration statement pursuant
      to Rule 415 of the Securities Act relating to the resale by certain
      holders of the Notes, and in each case, to use its best efforts to cause
      such registration statements to be declared effective.

            (h) The DTC Letter of Representations. At the Closing Date, the DTC
      Letter of Representations will have been duly authorized, executed and
      delivered by, and (assuming the due authorization, execution and delivery
      thereof by the other parties thereto) will be a valid and binding
      agreement of, the Company, enforceable in accordance with its terms except
      as the enforcement thereof may be limited by bankruptcy, insolvency,
      fraudulent conveyance, reorganization, moratorium or other similar laws
      relating to or affecting the rights and remedies of creditors or by
      general equitable principles (whether considered in a proceeding at law or
      in equity).

            (i) Authorization of the Securities and the Exchange Securities. (i)
      The Notes to be issued to the Initial Purchasers are in the form
      contemplated by Section 10(a) of the Note Purchase Agreement and by the
      Indenture, have been duly authorized for issuance and sale pursuant to
      this Agreement and the Indenture and, at the Closing Date, will have been
      duly executed by the Company and, when authenticated in the manner
      provided for in the Indenture and delivered in exchange for the Existing
      Notes (and against payment of the purchase price for the Additional
      Notes), will constitute valid and binding agreements of the Company,
      enforceable in accordance with their terms, except as the enforcement
      thereof may be limited by bankruptcy, insolvency, fraudulent conveyance,
      reorganization, moratorium or other similar laws relating to or affecting
      the rights and remedies of creditors or by general equitable principles
      (whether considered in a proceeding at law or in equity) and will be
      entitled to the benefits of the Indenture; (ii) prior to their issuance,
      the Exchange Notes will have been duly and validly authorized for issuance
      by the Company, and when issued and authenticated in accordance with the
      terms of the Indenture, the Registration Rights Agreement and the Exchange

      Guarantees of the Notes and the Indenture conform, or will conform, in all
      material respects to the respective statements relating thereto contained

            (l) No Material Adverse Change. Except as otherwise disclosed in the
      Offering Memorandum, subsequent to the respective dates as of which
      information is given in the Offering Memorandum, (i) there has been no
      material adverse change or any development that could reasonably be
      expected to result in a material adverse change, in the condition,
      financial or otherwise, or in the business, assets, properties,
      liabilities (contingent or otherwise) or operations, of Holdings or the
      Company and its Subsidiaries considered as one entity (any such change or
      development is called a "Material Adverse Change"); (ii) Holdings, and the
      Company and its Subsidiaries considered as one entity, have not incurred
      any material liability or obligation, indirect, direct or contingent, not
      in

                                       6

      Company or to another Subsidiary of the Company) or repurchase or
      redemption by Holdings, the Company or any of its Subsidiaries of any
      class of capital stock.

            (m) Independent Accountants. Arthur Andersen LLP (the "Independent
      Accountants"), who have expressed their opinion with respect to the
      financial statements (which term as used in this Agreement includes the
      related notes thereto) included in the Offering Memorandum are independent
      public or certified public accountants with respect to the Company within
      the meaning of Regulation S-X under the Exchange Act.

            (n) Preparation of the Financial Statements. The consolidated
      financial statements of the Company, together with the related notes,
      included in the Offering Memorandum present fairly, in all material
      respects, the consolidated financial position of the Company and its
      Subsidiaries as of and at the dates indicated and the results of their
      operations and cash flows for the periods specified. The financial
      statements included in the Offering Memorandum comply as to form with the
      applicable requirements of the Securities Act. Such financial statements
      have been prepared in conformity with generally accepted accounting
      principles as applied in the United States of America applied on a
      consistent basis throughout the periods involved, except as may be
      expressly stated in the related notes thereto. The financial data with
      respect to the Company and its Subsidiaries set forth in the Offering
      Memorandum under the captions "Offering Memorandum Summary -- Summary
      Consolidated Historical and Pro Forma Financial and Operating Data,"
      "Unaudited Pro Forma Condensed Consolidated Financial Statements" and
      "Selected Historical Financial and Operating Data" present fairly, in all
      material respects, the historical financial information set forth therein
      on a basis consistent with that of the audited and unaudited financial
      statements contained in the Offering Memorandum. The unaudited pro forma
      financial data of the Company and its Subsidiaries, and the related notes
      thereto included in the Offering Memorandum present fairly, in all
      material respects, the information contained therein, have been prepared
      in accordance with the Commission's rules and guidelines with respect to
      pro forma financial statements and have been properly presented on the
      bases described therein, and the assumptions used in the preparation
      thereof are believed to be reasonable in light of then existing conditions
      and the adjustments used therein are appropriate to give effect to the
      transactions and circumstances referred to therein.

            (o) Incorporation and Good Standing of Company and its Subsidiaries.
      Each of Holdings, the Company and the Subsidiaries of the Company has been
      duly organized and is validly existing as a corporation, limited
      partnership or limited liability company, as the case may be, in good
      standing under the laws of the jurisdiction of its organization; each of
      Holdings, the Company and the Subsidiaries of the Company has the power
      and authority to own, lease and operate its properties and to conduct its
      business as described in the Offering Memorandum; and each of Holdings,
      the Company and the Subsidiary Guarantors has the power and authority to
      enter into and/or perform its obligations, as the case may be, under each
      of this Agreement, the Indenture, the Registration Rights

                                        7
<PAGE>
      Agreement, the DTC Letter of Representations, the Securities and the
      Exchange Securities to which it is a party. Each of Holdings, the Company
      and each of its Subsidiaries is duly qualified as a foreign corporation,
      limited liability company or limited partnership, as the case may be, to
      transact business and is in good standing in each jurisdiction in which
      such qualification is required, whether by reason of the ownership or
      leasing of property or the conduct of business, except for such
      jurisdictions where the failure to so qualify or to be in good standing
      would not, individually or in the aggregate, result in a Material Adverse
      Change.

            (p) Capitalization and Other Capital Stock Matters. At the date
      specified in such table, the Company had the authorized, issued and
      outstanding capitalization as set forth in the Offering Memorandum under
      the caption "Capitalization" under the heading "Actual." At the date
      specified in such table, on a consolidated basis, after giving pro forma
      effect to (i) the issuance and sale of the Securities pursuant hereto,
      (ii) the consummation of the Merger, (iii) the funding of the Credit
      Facilities, (iv) the Equity Contribution, (v) the Option Rollover, each as
      described in the Offering Memorandum, and (vi) the application of the
      proceeds from the issuance and sale of the Securities, the funding of the
      Credit Facilities, the Equity Contribution and the Option Rollover to the
      refinancing transactions described under the caption "Use of Proceeds" in
      the Offering Memorandum, the Company would have an authorized and
      outstanding capitalization as set forth in the Offering Memorandum under
      the caption "Capitalization" under the heading "Pro Forma." All of the
      outstanding shares of capital stock of Holdings and the Company have been
      duly authorized and validly issued, are fully paid and nonassessable. None
      of the outstanding shares of capital stock of Holdings or the Company were
      issued in violation of any preemptive rights, rights of first refusal or
      other similar rights to subscribe for or purchase securities of Holdings
      or the Company, as the case may be. Except for rights of first refusal or
      "tag-along" or "drag along" rights customarily contained in stockholders'
      agreements, partnership agreements or joint venture operating agreements,
      there are no authorized or outstanding options, warrants, preemptive
      rights, rights of first refusal or other rights to purchase, or equity or
      debt securities convertible into or exchangeable or exercisable for, any
      capital stock of Holdings or the Company or any of the Subsidiaries, other
      than those described in the Offering Memorandum. The description of
      Holdings' stock option, stock bonus, stock purchase and other stock plans
      or arrangements and the options or other rights granted thereunder, set
      forth in the Offering Memorandum accurately and fairly describes, in all
      material respects, such plans, arrangements, options and rights. As of the
      date hereof, all of the issued and outstanding capital stock of the
      Company has been duly authorized and validly issued, is fully paid and
      nonassessable and is owned directly by Holdings, free and clear of any
      security interest, mortgage, pledge, lien, encumbrance or claim except as
      described in the Offering Memorandum. In addition, all of the issued and
      outstanding capital stock of each Subsidiary, except as described in the
      Offering Memorandum, has been duly authorized and validly issued, is fully
      paid and nonassessable and is owned by the Company, directly or through
      subsidiaries, free and clear of any security interest, mortgage, pledge,
      lien, encumbrance or claim, except for any security interests, mortgages,
      pledges, liens, encumbrances or claims of the lenders existing under the
      Credit Agreement, dated as of October 17, 2001, among the Company, the
      Guarantors, Bank of America, N.A., as administrative agent, First Union
      National Bank, as

                                       8
<PAGE>
      syndication agent, The CIT Group/Business, Inc., as documentation agent,
      and the other lenders party thereto (such agreement, as amended from time
      to time, the "Existing Credit Agreement"). The only Subsidiaries of the
      Company are those Subsidiaries listed in Schedule C hereto.

            (q) Non-Contravention of Existing Instruments; No Further
      Authorizations or Approvals Required. None of Holdings, the Company or any
      of its Subsidiaries is in violation of its charter or by-laws or is in
      default or has violated any provision of, or committed or failed to
      perform any act which, with or without notice, lapse of time, or both,
      would reasonably be expected to constitute a default ("Default") under any
      indenture, mortgage, loan or credit agreement, note, contract, franchise,
      lease, license or other instrument to which Holdings, the Company or any
      of its Subsidiaries is a party or by which it or any of them may be bound
      or to which any of the property or assets of Holdings, the Company or any
      of its Subsidiaries is subject (each, an "Instrument"), except for such
      Defaults as would not, individually or in the aggregate, result in a
      Material Adverse Change or except for such defaults that have been waived
      in writing. The Company's and each Guarantor's execution, delivery and
      performance of this Agreement, the Company's and each Guarantor's
      execution and delivery of, and the performance by the Company and the
      Guarantors of, the Registration Rights Agreement and the Indenture, the
      Company's execution and delivery of, and the performance by the Company
      of, the DTC Letter of Representations, and the issuance and delivery of
      the Securities or the Exchange Securities, and consummation of the
      transactions contemplated hereby and thereby and by the Offering
      Memorandum (i) will not result in any violation of the provisions of the
      partnership agreement, operating agreement, charter or by-laws, as
      applicable, of Holdings, the Company or any of its Subsidiaries, (ii) will
      not conflict with or constitute a breach of, or Default or a Debt
      Repayment Triggering Event (as defined below) under, or result in the
      creation or imposition of any lien, charge or encumbrance upon any
      property or assets of Holdings, the Company or any of its Subsidiaries
      pursuant to, or require the consent of any other party to, any Instrument,
      except for such conflicts, breaches, Defaults, Debt Repayment Triggering
      Events, liens, charges or encumbrances as would not, individually or in
      the aggregate, result in a Material Adverse Change and (iii) will not
      result in any violation of any law, administrative regulation or
      administrative or court decree applicable to Holdings or the Company or
      any of its Subsidiaries except for such violations that would not,
      individually or in the aggregate, result in a Material Adverse Change. No
      consent, approval, authorization or other order of, or registration or
      filing with, any court or other governmental or regulatory authority or
      agency, is required for the Company's or each Guarantor's execution,
      delivery and performance of this Agreement, the Registration Rights
      Agreement, the DTC Letter of Representations or the Indenture, to which it
      is a party, or the issuance and delivery of the Securities or the Exchange
      Securities, or consummation of the transactions contemplated hereby and
      thereby and by the Offering Memorandum, except such as will be obtained by
      the Company or the Guarantors and are in full force and effect under the
      Securities Act, the Trust Indenture Act and such as may be required under
      state securities laws or the blue sky laws of any jurisdiction in
      connection with the purchase and distribution of the Securities by the
      Initial Purchasers in the manner contemplated herein and in the Offering
      Memorandum and in connection with Holdings', the Company's and the
      Subsidiary Guarantors' obligations under the

                                       9
<PAGE>
      Registration Rights Agreement. As used herein, a "Debt Repayment
      Triggering Event" means any event or condition which gives, or with the
      giving of notice or lapse of time would give, the holder of any note,
      debenture or other evidence of material indebtedness (or any person acting
      on such holder's behalf) the right to require the repurchase, redemption
      or repayment of all or a portion of such indebtedness by Holdings or the
      Company or any of its Subsidiaries.

            (r) No Material Actions or Proceedings. Except as otherwise
      disclosed in the Offering Memorandum, there are no legal or governmental
      actions, suits or proceedings pending or, to the best of the knowledge of
      Holdings and the Company, threatened (i) against or affecting Holdings or
      the Company or any of the Subsidiaries, (ii) which has as the subject
      thereof any property owned or leased by, Holdings, the Company or any of
      its Subsidiaries, where in any such case (A) there is a reasonable
      possibility that such action, suit or proceeding might be determined
      adversely to Holdings or the Company or such Subsidiary and (B) any such
      action, suit or proceeding, if so determined adversely, would reasonably
      be expected to result in a Material Adverse Change or materially and
      adversely affect the transactions contemplated by this Agreement.

            (s) Intellectual Property Rights. The Company and its Subsidiaries
      own, possess or license sufficient trademarks, trade names, patent rights,
      copyrights, licenses, approvals, trade secrets and other similar rights
      (collectively, "Intellectual Property Rights") reasonably necessary to
      conduct their businesses as now conducted; and the expected expiration of
      any of such Intellectual Property Rights would not result in a Material
      Adverse Change. Neither the Company nor any of its Subsidiaries has
      received any notice of infringement or conflict with asserted Intellectual
      Property Rights of others, which infringement or conflict, if the subject
      of an unfavorable decision, ruling or filing would reasonably be expected
      to result in a Material Adverse Change and, except as otherwise disclosed
      in the Offering Memorandum, neither the Company nor any of its
      Subsidiaries is in default under the terms of any license or similar
      agreement related to any Intellectual Property Rights necessary to conduct
      their business as now conducted or contemplated except as would not
      reasonably be expected to result in a Material Adverse Change.

            (t) All Necessary Permits, Etc. The Company and each of its
      Subsidiaries possess such valid and current certificates, authorizations
      or permits issued by the appropriate municipal, state, federal or foreign
      regulatory agencies or bodies necessary to conduct their respective
      businesses as now conducted except as would not reasonably be expected to
      result in a Material Adverse Change, and neither the Company nor any
      Subsidiary has received any notice of proceedings relating to the
      revocation or modification of, or non-compliance with, any such license,
      certificate, authorization or permit which, singly or in the aggregate, if
      the subject of an unfavorable decision, ruling or finding, could
      reasonably be expected to result in a Material Adverse Change.

            (u) Regulatory Matters. To the knowledge of Holdings, the Company
      and each Subsidiary Guarantor, none of (i) the Company, any of its
      Subsidiaries, or the officers, directors, employees, or agents (as defined

      person who has a direct or indirect ownership interest of 5% or more (as
      those terms are defined in 42 C.F.R. Part 420 Subpart C and 42 C.F.R.
      Section 1001.1001(a)(2)) in the Company or any Subsidiary, has been

      Subsidiary has a Medicare provider number, and a participating provider
      agreement in force with a Medicare Part B carrier, and materially meets
      all applicable Medicare conditions of coverage, in each locale, as
      applicable, in which the Company, such Subsidiary or such entity bills
      directly to Medicare for services furnished by the Company, such
      Subsidiary or such entity. The Company, a Subsidiary, or an entity owned
      in whole or in part by the Company or a Subsidiary has a Medicare provider
      number, and a participating provider agreement, and materially satisfies
      all applicable Medicaid conditions of coverage, in each state, as
      applicable, in which the Company, such Subsidiary, or such other entity
      bills directly to such state's Medicaid agency for services provided by
      the Company, such Subsidiary, or such other entity for Medicaid patients.

            (w) Title to Properties. Except as otherwise disclosed in the
      Offering Memorandum, the Company and each of its Subsidiaries has good and
      marketable title to all their properties and assets reflected as owned in
      the financial statements referred to in Section 1(n) above (or elsewhere
      in the Offering Memorandum), in each case free and clear of any security
      interests, mortgages, liens, encumbrances, equities, claims and other
      defects, except as would not reasonably be expected to result in a
      Material Adverse Change. Any real property, improvements, equipment and
      personal property held under lease by the Company or any of its
      Subsidiaries are held under valid and enforceable leases, except for such
      invalidations and unenforceabilities as would not reasonably be expected
      to result in a Material Adverse Change.

            (x) Material Agreements. The agreements, contracts or instruments
      listed as exhibits to the Annual Report and those listed in Schedule B
      attached hereto are the only material agreements, contracts or instruments
      binding upon Holdings and/or the Company and its Subsidiaries, or
      agreements, contracts or instruments that provide for the payments by
      Holdings, the Company or any of its Subsidiaries after the date hereof of
      $2 million or more.

            (y) Tax Law Compliance. The Company and its Subsidiaries have filed
      all material federal, state and foreign income and franchise tax returns
      required to be filed and have paid all taxes shown on such returns
      required to be paid by any of them which are due and payable and, if due
      and payable, any related or similar assessment, fine or penalty levied
      against any of them. The Company and each Subsidiary Guarantor has made
      adequate charges, accruals and reserves in the applicable financial
      statements referred to in Section 1(n) above in respect of all federal,
      state and foreign income and franchise taxes for all periods as to which
      the tax liability of the Company or any of its Subsidiaries has not been
      finally determined, except where such failure would not reasonably be
      expected to result in a Material Adverse Change.

            (z) Company Not an "Investment Company". Holdings and the Company
      have been advised of the rules and requirements under the Investment
      Company Act of 1940, as amended (the "Investment Company Act"). None of
      Holdings or the Company is an "investment company" within the meaning of
      Investment Company Act and each of Holdings and the Company will conduct
      its business in a manner so that it will not become subject to the
      Investment Company Act.

            (aa) Insurance. Each of the Company and its Subsidiaries are insured
      by recognized, financially sound institutions with policies in such
      amounts and with such deductibles and covering such risks as are generally
      deemed adequate and customary for their businesses including, but not
      limited to, policies covering real and personal property owned or leased
      by the Company and its Subsidiaries against theft, damage, destruction,
      acts of vandalism and earthquakes. The Company has no reason to believe
      that it or any Subsidiary will not be able (i) to renew its existing
      insurance coverage as and when such policies expire or (ii) to obtain
      comparable coverage from similar institutions as may be necessary or
      appropriate to conduct its business as now conducted and at a cost that
      would not result in a Material Adverse Change. To the best of the
      Company's knowledge, after due inquiry, neither the Company nor any
      Subsidiary has been denied

                                       13
<PAGE>
      any insurance coverage which it has sought or for which it has applied and
      there are no claims by the Company or any of its Subsidiaries under any
      current insurance policy as to which any insurance company or institution
      is denying, or will deny, liability or coverage or defending under a
      reservation of rights clause.

            (bb) No Price Stabilization or Manipulation. None of the Company,
      the Guarantors or any of their respective Affiliates has taken or will
      take, directly or indirectly, any action designed to or that might be
      reasonably expected to cause or result in stabilization or manipulation of
      the price of any security of the Company to facilitate the sale or resale
      of the Securities.

            (cc) Solvency. Holdings, the Company and each of the Company's
      Subsidiaries, taken as a whole, is Solvent. As used herein, the term
      "Solvent" means, with respect to Holdings, the Company and its
      Subsidiaries, taken as a whole, on a particular date, that on such date
      (i) such entity is able to pay its debts and other liabilities, contingent
      obligations and other commitments as they mature in the ordinary course of
      business, (ii) such entity does not intend to, and does not believe that
      it will, incur debts or liabilities beyond such entity's ability to pay as
      such debts and liabilities mature in their ordinary course, (iii) such
      entity is not engaged in a business or a transaction, and is not about to
      engage in a business or a transaction, for which such entity's assets
      would constitute unreasonably small capital after giving due consideration
      to the prevailing practice in the industry in which such entity is engaged
      or is to engage, (iv) the fair value of the assets of such entity is
      greater than the total amount of liabilities, including, without
      limitation, contingent liabilities, of such entity and (v) the present
      fair salable value of the assets of such entity is not less than the
      amount that will be required to pay the probable liability of such entity
      on its debts as they become absolute and matured. In computing the amount
      of contingent liabilities at any time, it is intended that such
      liabilities will be computed at the amount which, in light of all the
      facts and circumstances existing at such time, represents the amount that
      can reasonably be expected to become an actual or matured liability.

            (dd) No Unlawful Contributions or Other Payments. Neither the
      Company nor any of its Subsidiaries nor, to the best of the Company's or
      any Guarantor's knowledge, any employee or agent of the Company or any
      Subsidiary, has made any contribution or other payment to any official of,
      or candidate for, any federal, state or foreign office in violation of any
      law or of the character necessary to be disclosed in the Offering
      Memorandum in order to make the statements therein not misleading.

            (ee) Company's Accounting System. The Company and each of its
      Subsidiaries maintains a system of accounting controls sufficient to
      provide reasonable assurances that (i) transactions are executed in
      accordance with management's general or specific authorization; (ii)
      transactions are recorded as necessary to permit preparation of financial
      statements in conformity with generally accepted accounting principles as
      applied in the United States of America and to maintain accountability for
      assets; (iii) access to assets is permitted only in accordance with
      management's general or specific authorization; and (iv) the recorded
      accountability for assets is compared with

                                       14
<PAGE>
      existing assets at reasonable intervals and appropriate action is taken
      with respect to any differences.

            (ff) Compliance with Environmental Laws. Except as otherwise
      disclosed in the Offering Memorandum or as would not, individually or in
      the aggregate, result in a Material Adverse Change (i) the Company and
      each of its Subsidiaries have all permits, authorizations and approvals
      required under any Environmental Laws and are in compliance with their
      requirements, (ii) neither the Company nor any of its Subsidiaries, to the
      knowledge of the Company, after due inquiry, is in violation of any
      federal, state, local or foreign law or regulation relating to pollution
      or protection of human health or the environment (including, without
      limitation, ambient air, surface water, groundwater, land surface or
      subsurface strata) or wildlife, including without limitation, laws and
      regulations relating to emissions, discharges, releases or threatened
      releases of chemicals, pollutants, contaminants, wastes, toxic substances,
      hazardous substances, petroleum and petroleum products (collectively,
      "Materials of Environmental Concern"), or otherwise relating to the
      manufacture, processing, distribution, use, treatment, storage, disposal,
      transport or handling of Materials of Environmental Concern (collectively,
      "Environmental Laws"), which violation includes, but is not limited to,
      noncompliance with any permits or other governmental authorizations
      required for the operation of the business of the Company or its
      Subsidiaries under applicable Environmental Laws, or noncompliance with
      the terms and conditions thereof, nor has the Company or any of its
      Subsidiaries received any written communication, whether from a
      governmental authority, citizens group, employee or otherwise, that
      alleges that the Company or any of its Subsidiaries is in violation of any
      Environmental Law; (iii) there is, to the knowledge of the Company, after
      due inquiry, no claim, action or cause of action filed with a court or
      governmental authority, no investigation with respect to which the Company
      or any Subsidiary has received written notice, and no written notice by
      any person or entity alleging potential liability for investigatory costs,
      cleanup costs, governmental responses costs, natural resources damages,
      property damages, personal injuries, attorneys' fees or penalties arising
      out of, based on or resulting from the presence, or release into the
      environment, of any Material of Environmental Concern at any location
      owned, leased or operated by the Company or any of its Subsidiaries, now
      or in the past (collectively, "Environmental Claims"), pending or, to the
      best of the Company's or any Guarantor's knowledge, threatened against the
      Company or any of its Subsidiaries or any person or entity whose liability
      for any Environmental Claim the Company or any of its Subsidiaries has
      retained or assumed either contractually or by operation of law; and (iv)
      to the knowledge of the Company, there are no past or present actions,
      activities, circumstances, conditions, events or incidents, including,
      without limitation, the release, emission, discharge, presence or disposal
      of any Material of Environmental Concern, that reasonably could result in
      a violation of any Environmental Law or form the basis of a potential
      Environmental Claim against the Company or any of its Subsidiaries or
      against any person or entity whose liability for any Environmental Claim
      the Company or any of its Subsidiaries has retained or assumed either
      contractually or by operation of law.

            (gg) ERISA Compliance. The Company and its Subsidiaries and any
      "employee benefit plan" (as defined under the Employee Retirement Income
      Security Act of 1974, as amended, and the regulations and published
      interpretations thereunder

                                       15
<PAGE>
      (collectively, "ERISA")) established or maintained by the Company, its
      Subsidiaries or their "ERISA Affiliates" (as defined below) are in
      compliance in all respects with ERISA or, if not in compliance, would not
      reasonably be expected to result in a Material Adverse Change. "ERISA
      Affiliate" means, with respect to the Company or a Subsidiary, any member
      of any group of organizations described in Sections 414(b), (c), (m) or
      (o) of the Internal Revenue Code of 1986, as amended, and the regulations
      and published interpretations thereunder (the "Code") of which the Company
      or such Subsidiary is a member. No "reportable event" (as defined under
      ERISA) has occurred or is reasonably expected to occur with respect to any
      "employee benefit plan" established or maintained by the Company, its
      Subsidiaries or any of their ERISA Affiliates. No "employee benefit plan"
      established or maintained by the Company, its Subsidiaries or any of their
      ERISA Affiliates, if such "employee benefit plan" were terminated, would
      have any "amount of unfunded benefit liabilities" (as defined under
      ERISA). Neither the Company, its Subsidiaries nor any of their ERISA
      Affiliates has incurred or reasonably expects to incur any liability under
      (i) Title IV of ERISA with respect to termination of, or withdrawal from,
      any "employee benefit plan" or (ii) Sections 412, 4971, 4975 or 4980B of
      the Code. Each "employee benefit plan" established or maintained by the
      Company, its Subsidiaries or any of their ERISA Affiliates that is
      intended to be qualified under Section 401(a) of the Code is so qualified
      and nothing has occurred, whether by action or failure to act, which would
      cause the loss of such qualification.

            (hh) Regulation S Compliance. The Company, the Guarantors and their
      respective Affiliates and all authorized persons acting on their behalf
      (other than the Initial Purchasers, as to whom the Company and the
      Guarantors make no representation) have complied with and will comply with
      the offering restrictions requirements of Regulation S in connection with
      the offering of the Securities outside the United States and, in
      connection therewith, the Offering Memorandum will contain the disclosure
      required by Rule 902(h).

            (ii) Taxes; Fees. There are no stamp or other issuance or transfer
      taxes or duties or other similar fees or charges required to be paid in
      connection with the execution and delivery of this Agreement or the
      issuance or sale by the Company of the Securities.

            (jj) No Labor Disputes. As of the date hereof, (i) there is no
      unfair labor practice complaint pending against the Company or any of its
      Subsidiaries or, to the best knowledge of the Company, threatened against
      any of them, before the National Labor Relations Board or any state or
      local labor relations board, and no significant grievance or significant
      arbitration proceeding arising out of or under any collective bargaining
      agreement is so pending against the Company or any of its Subsidiaries or,
      to the best knowledge of the Company, threatened against any of them, (ii)
      there is no material strike, labor dispute, slowdown or stoppage pending
      against the Company or any of its Subsidiaries or, to the knowledge of the
      Company, threatened against the Company and (iii) the Company is not aware
      of any existing, threatened or imminent labor disturbance by the employees
      of any of its principal customers, suppliers, manufacturers or
      contractors, in each case which is likely to result in a Material Adverse
      Change.

                                       16
<PAGE>
            Any certificate signed by an officer of the Company or any Guarantor
and delivered to the Initial Purchasers pursuant to this Agreement or to counsel
for the Initial Purchasers shall be deemed to be a representation and warranty
by the Company or such Guarantor to the Initial Purchasers as to the matters set
forth therein.

            Section 2. Purchase, Sale and Delivery of the Securities.

            (a) The Securities. The Company agrees to (x) issue to the Initial
      Purchasers, in exchange for all of the Existing Notes held by the Initial
      Purchasers, the aggregate principal amount of Notes set forth on Schedule
      D hereto and (y) issue and sell to the Initial Purchasers, acting
      severally and not jointly, the aggregate principal amount of Additional
      Notes set forth on Schedule D hereto at a purchase price equal to 97% of
      the principal amount thereof, payable on the Closing Date (it being
      acknowledged that the discount of 3% shall be in satisfaction of the fees
      payable with respect to the Additional Notes by the Company pursuant to
      the second sentence of Section 2 of the Fee Letter). The Notes shall be
      resold by the Initial Purchasers at par; provided that, with the consent
      of J.W. Childs Associates, L.P. and The Halifax Group, L.L.C., the Initial
      Purchasers may resell the Notes at a price below par.

            (b) The Closing Date. Delivery of certificates for the Securities in
      definitive form to be issued and sold to the Initial Purchasers (and
      payment of the purchase price for the Additional Notes) shall be made at
      the offices of Shearman & Sterling, 599 Lexington Avenue, New York, New
      York 10022-6069 (or such other place as may be agreed to by the Company
      and Banc of America Securities LLC) at 9:00 a.m. New York City time, on
      the Exchange Date (as defined in the Note Purchase Agreement), or such
      other time and date as Banc of America Securities LLC shall designate by
      notice to the Company (the time and date of such closing are called the
      "Closing Date"). The Company hereby acknowledges that circumstances under
      which the Initial Purchasers may provide notice to postpone the Closing
      Date as originally scheduled include, but are in no way limited to, any
      determination by the Company or the Initial Purchasers to recirculate to
      investors copies of an amended or supplemented Offering Memorandum.

            (c) Delivery of the Notes. The Notes shall be delivered as provided
      in Section 10(a) of the Note Purchase Agreement. The certificates for the
      Notes shall be in such denominations and registered in the name of the
      Depositary or its nominee, pursuant to the DTC Letter of Representations,
      and shall be made available for inspection on the business day preceding
      the Closing Date at a location in New York City, as the Initial Purchasers
      may designate. Time shall be of the essence.

            (d) Delivery of Offering Memorandum to the Initial Purchasers. Not
      later than 12:00 p.m. on the second business day following the date of
      this Agreement, the Company shall deliver or cause to be delivered copies
      of the Offering Memorandum in such quantities and at such places as the
      Initial Purchasers shall reasonably request.

            (e) Initial Purchasers as Qualified Institutional Buyers. Each
      Initial Purchaser represents and warrants to, and agrees with, the Company
      that (i) it is a "qualified institutional buyer" within the meaning of
      Rule 144A (a "Qualified

                                       17
<PAGE>
      Institutional Buyer"), and (ii) with respect to those Securities sold in
      reliance on Regulation S, (A) has not engaged and will not engage in any
      direct selling efforts within the meaning of Regulation S and (B) has
      complied and will comply with the offering restrictions requirements of
      Regulations S.

            Section 3. Covenants. The Company and each Guarantor further jointly
and severally covenant and agree with each Initial Purchaser as follows:

            (a) The Initial Purchasers' Review of Proposed Amendments and
      Supplements. Prior to amending or supplementing the Offering Memorandum
      (including any amendment or supplement through incorporation by reference
      of any report filed under the Exchange Act), the Company shall furnish to
      the Initial Purchasers for review a copy of each such proposed amendment
      or supplement, and the Company shall not use any such proposed amendment
      or supplement to which any Initial Purchaser reasonably objects in writing
      within 3 business days (with advice from its independent counsel).

            (b) Amendments and Supplements to the Offering Memorandum and Other
      Securities Act Matters. If, prior to the completion of the placement of
      the Securities by the Initial Purchasers with the Subsequent Purchasers,
      any event shall occur or condition exist as a result of which it is
      necessary to amend or supplement the Offering Memorandum in order to make
      the statements therein, in the light of the circumstances when the
      Offering Memorandum is delivered to a Subsequent Purchaser, not
      misleading, or if in the opinion of the Initial Purchasers or counsel for
      the Initial Purchasers it is otherwise necessary to amend or supplement
      the Offering Memorandum to comply with law, the Company agrees to promptly
      prepare (subject to Section 3(a) hereof), and furnish at its own expense
      to the Initial Purchasers, amendments or supplements to the Offering
      Memorandum so that the statements in the Offering Memorandum as so amended
      or supplemented will not, in the light of the circumstances when the
      Offering Memorandum is delivered to a Subsequent Purchaser, be misleading
      or so that the Offering Memorandum, as amended or supplemented, will
      comply with law.

            The Company and the Guarantors hereby expressly acknowledge that the
      indemnification and contribution provisions of Sections 8 and 9 hereof are
      specifically applicable and relate to each offering memorandum,
      registration statement, prospectus, amendment or supplement referred to in
      this Section 3(b).

            (c) Copies of the Offering Memorandum. The Company agrees to furnish
      the Initial Purchasers, without charge, as many copies of the Offering
      Memorandum and any amendments and supplements thereto as they shall have
      reasonably requested prior to or at the time of the original printing of
      the Offering Memorandum or any amendment or supplement thereto.

            (d) Blue Sky Compliance. Holdings, the Company and the Subsidiary
      Guarantors shall cooperate with the Initial Purchasers and counsel for the
      Initial Purchasers to qualify or register the Securities for sale under
      (or obtain exemptions from the application of) the Blue Sky or state
      securities laws of those jurisdictions designated by the Initial
      Purchasers, shall comply with such laws and shall continue such

                                       18
<PAGE>
      qualifications, registrations and exemptions in effect so long as required
      for the distribution of the Securities. Holdings, the Company and the
      Subsidiary Guarantors shall not be required to qualify as a foreign
      corporation or to take any action that would subject it to general service
      of process in any such jurisdiction where it is not presently qualified or
      where it would be subject to taxation as a foreign corporation. Holdings
      and the Company will advise the Initial Purchasers promptly of the
      suspension of the qualification or registration of (or any such exemption
      relating to) the Securities for offering, sale or trading in any
      jurisdiction or any initiation or threat of any proceeding for any such
      purpose, and in the event of the issuance of any order suspending such
      qualification, registration or exemption, Holdings, the Company and the
      Subsidiary Guarantors shall use their reasonable best efforts to obtain
      the withdrawal thereof at the earliest possible moment.

            (e) Depositary. The Company will cooperate with the Initial
      Purchasers and use its reasonable best efforts to permit the Securities to
      be eligible for clearance and settlement through the facilities of the
      Depositary.

            (f) Additional Issuer Information. Prior to the completion of the
      placement of the Securities by the Initial Purchasers with the Subsequent
      Purchasers, the Company, or, if permitted by the Exchange Act, Holdings,
      shall file, on a timely basis, with the Commission all reports and
      documents required to be filed under Section 13 or 15 of the Exchange Act;
      provided that if such filings are being made by Holdings, rather than by
      the Company, such filings shall adequately disclose the Company's results
      of operations and financial condition in the "Management's Discussion and
      Analysis of Financial Condition and Results of Operations" section in at
      least such detail as would be required if the Company were filing such
      report. In addition, at any time Holdings or the Company is not subject to
      Section 13 or 15 of the Exchange Act, Holdings and the Company covenant
      that they will furnish, at their expense, upon request, to registered
      holders of Securities within the time periods specified in the Exchange
      Act (i) all quarterly and annual reports that would be required to be
      filed with the Commission on Forms 10-Q and 10-K if Holdings or the
      Company were required to file such Forms, (including, in each case,
      financial information and a "Management's Discussion and Analysis of
      Financial Condition and Results of Operations" and, with respect to the
      annual information only, a report on the annual financial statements by
      Holdings' and the Company's certified independent accountants); and (ii)
      all current reports that would be required to be filed with the Commission
      on Form 8-K if Holdings or the Company were required to file such reports.
      In addition, following the date the Company is required to consummate the
      exchange offer contemplated by the Registration Rights Agreement, whether
      or not required by the Commission, Holdings and the Company will file a
      copy of all of the information and reports referred to in clauses (i) and
      (ii) above with the Commission for public availability within the time
      periods specified in the Commission's rules and regulations (unless the
      Commission will not accept such a filing) and make such information
      available to securities analysts and prospective purchasers of Securities
      upon request. In addition, the Company and the Guarantors agree that, for
      so long as Securities (but not the Exchange Securities) remain
      outstanding, they will furnish to holders and beneficial owners of
      Securities and to securities analysts and prospective purchasers of
      Securities, upon their request, the information (together with the
      documents

                                       19

            (g) Future Agreement Not to Offer or Sell Additional Securities.
      Holdings and the Company, during the period of 180 days following the date
      of the Offering Memorandum, will not, without the prior written consent of
      Banc of America Securities LLC (which consent may be withheld at the sole
      discretion of such Initial Purchaser), directly or indirectly, sell,
      offer, contract or grant any option to sell, pledge, transfer or establish
      an open "put equivalent position" within the meaning of Rule 16a-1(h)
      under the Exchange Act, or otherwise dispose of or transfer, or announce
      the offering of, or file any registration statement under the Securities
      Act in respect of, any debt securities of the Company or securities
      exchangeable for or convertible into debt securities of the Company (other
      than to register the Exchange Securities).

      the Company mailed generally to holders of its capital stock or debt
      securities (including the holders of the Securities).

            (i) No Integration. Each of Holdings and the Company agrees that it
      will not and will cause its affiliates not to, make any offer or sale of
      securities of any class if, as a result of the doctrine of "integration"
      referred to in Rule 502 under the Securities Act, such offer or sale would
      render invalid (for the purpose of (i) the issuance and sale of the
      Securities by the Company to the Initial Purchaser, (ii) the resale of the
      Securities by the Initial Purchasers to Subsequent Purchasers or (iii) the
      resale of the Securities by such Subsequent Purchasers to others) the
      exemption from the registration requirements of the Securities Act
      provided by Section 4(2) thereof or by Rule 144A or by Regulation S
      thereunder or otherwise.

      Purchase Agreement for the time period and upon the other terms stated in
      the Offering Memorandum.

            (k) PORTAL. The Company will use its reasonable best efforts to
      cause such Notes when issued to be eligible for the National Association
      of Securities Dealers, Inc. PORTAL market (the "PORTAL market").

      action necessary to enable Standard & Poor's Ratings Services, a division
      of McGraw Hill, Inc. ("S&P"), and Moody's Investor Services, Inc.

      the form of which is attached as Exhibit C.

            (e) Officers' Certificate. On the Closing Date, each of Holdings and
      the Company shall deliver to the Initial Purchasers written certificates,
      executed by the Chief Executive Officer, President, Executive Vice

      the case may be, and the Chief Financial Officer or Chief Accounting

                  (i) for the period from and after the date of this Agreement

            inquiry, there has not occurred any Material Adverse Change;

                  (ii) for the period from the date of this Agreement and prior
            to the Closing Date, there has not occurred any downgrading, nor has
            any notice been given of any intended or potential downgrading or of
            any review for a possible change that does not indicate the
            direction of the possible change, in the rating accorded any
            securities of the Company or any of its Subsidiaries by any
            "nationally recognized statistical rating organization", as such

            respects (without giving effect to any limitation as to
            "materiality" or "Material Adverse Change" set forth therein) with
            the same force and effect as though expressly made on and as of the
            Closing Date; and

                  (iv) the Company and the Guarantors have complied in all
            material respects with all the agreements and satisfied all the
            conditions on its part to be performed or satisfied at or prior to
            the Closing Date.

            (f) Bring-down Comfort Letters. The Company shall use its best
      efforts to cause the Independent Accountants to deliver to the Initial

                                       22
<PAGE>
      on the Closing Date, a letter dated such date, in form and substance
      satisfactory to the Initial Purchasers, to the effect that such
      Independent Accountants reaffirm the statements made in the letter
      furnished by them pursuant to subsection (a) of this Section 5, except
      that the specified date referred to therein for the carrying out of
      procedures shall be no more than three business days prior to the Closing

            (g) Registration Rights Agreement. The Company and the Guarantors
      shall enter into the Registration Rights Agreement and deliver to the

            (h) Additional Documents. On or before the Closing Date, the Company
      shall deliver to the Initial Purchasers and counsel for the Initial
      Purchasers such information and documents as the Initial Purchasers and
      such counsel may reasonably require for the purposes of enabling them to
      pass upon the issuance and sale of the Securities as contemplated herein,
      or in order to evidence the accuracy of any of the representations and
      warranties, or the satisfaction of any of the conditions or agreements,
      herein contained.

            Section 6. Reimbursement of Initial Purchasers' Expenses. If the
issuance and sale to the Initial Purchasers of the Securities on the Closing
Date is not consummated because of any refusal, inability or failure on the part
of the Company to perform any agreement herein or to comply with any provision
hereof, the Company agrees to, and Holdings agrees to cause the Company to,
reimburse the Initial Purchasers upon demand for all reasonable out-of-pocket
expenses that shall have been incurred by the Initial Purchasers in connection
with the proposed offering and sale of the Securities.

            Section 7. Offer, Sale and Resale Procedures. The Initial
Purchasers, on the one hand, and Holdings and the Company, on the other hand,
hereby establish and agree to observe the following procedures in connection
with the offer and sale of the Securities:

            (a) Offers and Sales Only to Qualified Institutional Buyers and
      Non-U.S. Persons. Offers and sales of the Securities will be made only by
      the Initial Purchasers or Affiliates thereof qualified to do so in the
      jurisdictions in which such offers or sales are made. Each such offer or
      sale shall only be made (A) to persons whom the offeror or seller
      reasonably believes to be qualified institutional buyers (as defined in
      Rule 144A under the Securities Act) or (B) non-U.S. persons outside the
      United States to whom the offeror or seller reasonably believes offers and
      sales of the Securities may be made in reliance upon Regulation S under
      the Securities Act, upon the terms and conditions set forth in Annex I
      hereto, which Annex I is hereby expressly made a part hereof.

            (b) No General Solicitation. The Securities will be offered by
      approaching prospective Subsequent Purchasers on an individual basis. No
      general solicitation or general advertising (within the meaning of Rule
      502(c) under the Securities Act) will be used in the United States in
      connection with the offering of the Securities.

            (c) Restrictions on Transfer. Upon original issuance by the Company,
      and until such time as the same is no longer required under the applicable
      requirements of the Securities Act, the Notes (and all securities issued
      in exchange therefor or in substitution

                                       23
<PAGE>
      thereof, other than the Exchange Securities) shall bear a legend
      substantially in the form set forth in Section 10(d) of the Note Purchase
      Agreement.

Following the sale of the Securities by the Initial Purchasers to Subsequent
Purchasers pursuant to the terms hereof, the Initial Purchasers shall not be
liable or responsible to the Company for any losses, damages or liabilities
suffered or incurred by the Company, including any losses, damages or
liabilities under the Securities Act, arising from or relating to any resale or
transfer of any Security.

            Section 8. Indemnification.

            (a) Indemnification of the Initial Purchasers. Each of Holdings, the
      Company and each of the Subsidiary Guarantors jointly and severally agrees
      to indemnify and hold harmless each Initial Purchaser, its directors,
      officers and employees, and each person, if any, who controls any Initial
      Purchaser within the meaning of Section 15 of the Securities Act and
      Section 20 of the Exchange Act against any loss, claim, damage, liability
      or expense, as incurred, to which such Initial Purchaser or such
      controlling person may become subject, under the Securities Act, the
      Exchange Act or other federal or state statutory law or regulation, or at
      common law or otherwise (including in settlement of any litigation, if
      such settlement is effected with the written consent of Holdings and the
      Company), insofar as such loss, claim, damage, liability or expense (or
      actions in respect thereof as contemplated below) arises out of or is
      based (i) upon any untrue statement or alleged untrue statement of a
      material fact contained in the Preliminary Offering Memorandum or the
      Offering Memorandum (or any amendment or supplement thereto), or the
      omission or alleged omission therefrom of a material fact necessary in
      order to make the statements therein, in the light of the circumstances
      under which they were made, not misleading; or (ii) in whole or in part
      upon any inaccuracy in the representations and warranties of the Company
      or any Guarantor contained herein; or (iii) in whole or in part upon any
      failure of the Company or any Guarantor to perform its obligations
      hereunder or under law; or (iv) any act or failure to act or any alleged
      act or failure to act by any Initial Purchaser in connection with, or
      relating in any manner to, the offering contemplated hereby, and which is
      included as part of or referred to in any loss, claim, damage, liability
      or action arising out of or based upon any matter covered by clause (i)
      above to the extent such loss, claim, damage, liability or expense is not
      covered in items (i) through (iii) (subject to the limitations set forth
      below), provided that none of the Company or any Guarantor shall be liable
      under this clause (iv) to the extent that a court of competent
      jurisdiction shall have determined by a final judgment that such loss,
      claim, damage, liability or action resulted directly from any such acts or
      failures to act undertaken or omitted to be taken by such Initial
      Purchaser through its gross negligence or willful misconduct; and to
      reimburse such Initial Purchaser and each such controlling person for any
      and all expenses (including the fees and disbursements of counsel chosen
      by Banc of America Securities LLC) as such expenses are reasonably
      incurred by such Initial Purchaser or such controlling person in
      connection with investigating, defending, settling, compromising or paying
      any such loss, claim, damage, liability, expense or action; provided,
      however, that the foregoing indemnity agreement shall not apply to any
      loss, claim, damage, liability or expense to the extent, but only to the
      extent, arising out of or based upon any untrue statement or alleged
      untrue statement or omission or alleged

                                       24
<PAGE>
      omission made in reliance upon and in conformity with written information
      furnished to the Company by the Initial Purchasers expressly for use in
      any Preliminary Offering Memorandum or the Offering Memorandum (or any
      amendment or supplement thereto). The indemnity agreement set forth in
      this Section 8(a) shall be in addition to any liabilities that Holdings or
      the Company and the Subsidiary Guarantors may otherwise have.

            (b) Indemnification of the Company and the Guarantors and their
      Directors and Officers. Each Initial Purchaser agrees to indemnify and
      hold harmless Holdings and the Company and each of their respective
      directors and each person, if any, who controls the Company or Holdings
      within the meaning of the Securities Act or the Exchange Act against any
      loss, claim, damage, liability or expense, as incurred, to which Holdings
      or the Company or any such director, or controlling person may become
      subject, under the Securities Act, the Exchange Act, or other federal or
      state statutory law or regulation, or at common law or otherwise
      (including in settlement of any litigation, if such settlement is effected
      with the written consent of the Initial Purchasers), insofar as such loss,
      claim, damage, liability or expense (or actions in respect thereof as
      contemplated below) arises out of or is based upon any untrue or alleged
      untrue statement of a material fact contained in any Preliminary Offering
      Memorandum or the Offering Memorandum (or any amendment or supplement
      thereto), or arises out of or is based upon the omission or alleged
      omission to state therein a material fact required to be stated therein or
      necessary in order to make the statements therein in the light of the
      circumstances under which they were made not misleading, in each case to
      the extent, but only to the extent, that such untrue statement or alleged
      untrue statement or omission or alleged omission was made in any
      Preliminary Offering Memorandum or the Offering Memorandum (or any
      amendment or supplement thereto), in reliance upon and in conformity with
      written information furnished to the Company by the Initial Purchasers
      expressly for use therein; and to reimburse Holdings and the Company or
      any such director or controlling person for any legal and other expenses
      reasonably incurred by Holdings or the Company or any such director or
      controlling person in connection with investigating, defending, settling,
      compromising or paying any such loss, claim, damage, liability, expense or
      action. Holdings and the Company hereby acknowledge that the only
      information that the Initial Purchasers have furnished to the Company
      expressly for use in any Preliminary Offering Memorandum or the Offering
      Memorandum (or any amendment or supplement thereto) are the statements set
      forth in (A) the seventh full paragraph on introductory page ii of the
      Offering Memorandum, (B) the second sentence under the caption "Risk
      Factors -- You cannot be sure that an active trading market will develop
      for these notes," and (C) the first sentence of the third paragraph, the
      first three sentences of the fourth paragraph, the third sentence of the
      sixth paragraph and the eighth paragraph under the caption "Plan of
      Distribution" in the Offering Memorandum; and the Initial Purchasers
      confirm that such statements are correct. The indemnity agreement set
      forth in this Section 8(b) shall be in addition to any liabilities that
      each Initial Purchaser may otherwise have.

            (c) Notifications and Other Indemnification Procedures. Promptly
      after receipt by an indemnified party under this Section 8 of notice of
      the commencement of any action, such indemnified party will, if a claim in
      respect thereof is to be made against an indemnifying party under this
      Section 8, notify the indemnifying party in writing of

                                       25
<PAGE>
      the commencement thereof, but the omission so to notify the indemnifying
      party will not relieve it from any liability which it may have to any
      indemnified party for contribution or otherwise than under the indemnity
      agreement contained in this Section 8 or to the extent it is not
      prejudiced as a proximate result of such failure. In case any such action
      is brought against any indemnified party and such indemnified party seeks
      or intends to seek indemnity from an indemnifying party, the indemnifying
      party will be entitled to participate in and, to the extent that it shall
      elect, jointly with all other indemnifying parties similarly notified, by
      written notice delivered to the indemnified party promptly after receiving
      the aforesaid notice from such indemnified party, to assume the defense
      thereof with counsel reasonably satisfactory to such indemnified party;
      provided, however, if the defendants in any such action include both the
      indemnified party and the indemnifying party and the indemnified party
      shall have reasonably concluded that a conflict may arise between the
      positions of the indemnifying party and the indemnified party in
      conducting the defense of any such action or that there may be legal
      defenses available to it and/or other indemnified parties which are
      different from or additional to those available to the indemnifying party,
      the indemnified party or parties shall have the right to select separate
      counsel to assume such legal defenses and to otherwise participate in the
      defense of such action on behalf of such indemnified party or parties.
      Upon receipt of notice from the indemnifying party to such indemnified
      party of such indemnifying party's election so to assume the defense of
      such action and approval by the indemnified party of counsel, the
      indemnifying party will not be liable to such indemnified party under this
      Section 8 for any legal or other expenses subsequently incurred by such
      indemnified party in connection with the defense thereof unless (i) the
      indemnified party shall have employed separate counsel in accordance with
      the proviso to the next preceding sentence (it being understood, however,
      that the indemnifying party shall not be liable for the expenses of more
      than one separate counsel (together with local counsel), approved by the
      indemnifying party (Banc of America Securities LLC in the case of Section
      8 and Section 9), representing the indemnified parties who are parties to
      such action) or (ii) the indemnifying party shall not have employed
      counsel satisfactory to the indemnified party to represent the indemnified
      party within a reasonable time after notice of commencement of the action,
      in each of which cases the fees and expenses of counsel shall be at the
      expense of the indemnifying party.

            (d) Settlements. The indemnifying party under this Section 8 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
      non-appealable judgment for the plaintiff, the indemnifying party agrees
      to indemnify the indemnified party against any loss, claim, damage,
      liability or expense 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
      Section 8(c) hereof, the indemnifying party agrees that it shall be liable
      for any settlement of any proceeding effected without its written consent
      if (i) such settlement is entered into more than 45 days after receipt by
      such indemnifying party of the aforesaid request, (ii) such indemnifying
      party shall have received notice of the final terms of such proposed
      settlement as soon as practicable prior to such settlement being entered
      into and (iii) such indemnifying party shall not have reimbursed the
      indemnified party in accordance with such request prior to the date of
      such settlement. No

                                       26
<PAGE>
      indemnifying party shall, without the prior written consent of the
      indemnified party, effect any settlement, compromise or consent to the
      entry of judgment in any pending or threatened action, suit or proceeding
      in respect of which any indemnified party is or could have been a party
      and indemnity was or could have been sought hereunder by such indemnified
      party, unless such settlement, compromise or consent includes an
      unconditional release of such indemnified party from all liability on
      claims that are the subject matter of such action, suit or proceeding.

            Section 9. Contribution. If the indemnification provided for in
Section 8 is for any reason held to be unavailable to or otherwise insufficient
to hold harmless an indemnified party in respect of any losses, claims, damages,
liabilities or expenses referred to therein, then each indemnifying party shall
contribute to the aggregate amount paid or payable by such indemnified party, as
incurred, as a result of any losses, claims, damages, liabilities or expenses
referred to therein (i) in such proportion as is appropriate to reflect the
relative benefits received by Holdings, the Company and the Subsidiary
Guarantors, on the one hand, and the Initial Purchasers, on the other hand, from
the offering of the Securities pursuant to this Agreement 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) above but also the relative fault of Holdings and the
Company and the Subsidiary Guarantors, on the one hand, and the Initial
Purchasers, on the other hand, in connection with the statements or omissions or
inaccuracies in the representations and warranties herein which resulted in such
losses, claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations. The relative benefits received by Holdings and the
Company and the Subsidiary Guarantors, on the one hand, and the Initial
Purchasers, on the other hand, in connection with the offering of the Securities
pursuant to this Agreement shall be deemed to be in the same respective
proportions as the total net proceeds, if any, from the offering of the
Securities pursuant to this Agreement (before deducting expenses) received by
the Company and the total discount, if any, received by the Initial Purchasers
bear to the aggregate initial offering price of the Securities. The relative
fault of Holdings, the Company and the Subsidiary Guarantors, on the one hand,
and the Initial Purchasers, on the other hand, shall be determined by reference
to, among other things, whether any such untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact or any
such inaccurate or alleged inaccurate representation or warranty relates to
information supplied by Holdings, the Company or the Subsidiary Guarantors, on
the one hand, or the Initial Purchasers, on the other hand, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

            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 8(c), any legal or
other fees or expenses reasonably incurred by such party in connection with
investigating or defending any action or claim. The provisions set forth in
Section 8(c) with respect to notice of commencement of any action shall apply if
a claim for contribution is to be made under this Section 9; provided that no
additional notice shall be required with respect to any action for which notice
has been given under Section 8(c) for purposes of indemnification.

                                       27

            The Company, the Guarantors and the Initial Purchasers agree that it
would not be just and equitable if contribution pursuant to this Section 9 were
determined by pro rata allocation (even if the Initial Purchasers were treated
as one entity for such purpose) or by any other method of allocation which does
not take account of the equitable considerations referred to in this Section 9.

            Notwithstanding the provisions of this Section 9, the Initial
Purchasers shall not be required to contribute any amount in excess of the
discount received by the Initial Purchasers in connection with the Securities
distributed by them. 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. For purposes of this Section 9, each director, officer and
employee of any Initial Purchaser and each person, if any, who controls any
Initial Purchaser within the meaning of the Securities Act and the Exchange Act
shall have the same rights to contribution as the Initial Purchasers, and each
director of Holdings and the Company and each person, if any, who controls
Holdings and the Company within the meaning of the Securities Act and the
Exchange Act shall have the same rights to contribution as Holdings and the
Company.

            Section 10. [Intentionally Omitted.]

            Section 11. Representations and Indemnities to Survive Delivery. The
respective indemnities, agreements, representations, warranties and other
statements of Holdings and the Company of their officers and of the Initial
Purchasers set forth in or made pursuant to this Agreement will remain in full
force and effect, regardless of any investigation made by or on behalf of the
Initial Purchasers, Holdings or the Company or any of its or their partners,
officers or directors or any controlling person, as the case may be, and will
survive delivery of and payment for the Securities sold hereunder and any
termination of this Agreement.

                       FORM OF OPINION OF KAYE SCHOLER LLP

            (i) Each of Holdings and the Company has been duly incorporated and
is validly existing as a corporation in good standing under the laws of the
State of Delaware.

            (ii) Each of Holdings and the Company has the corporate power and
authority to own, lease and operate its properties and to conduct its business
as described in the Offering Memorandum and to enter into and perform its
obligations under the Purchase Agreement and the other Transaction Documents to
which it is a party.

            (iii) All of the issued and outstanding capital stock of each of
Holdings and the Company has been duly authorized and, to our knowledge, has
been validly issued, is fully paid and non-assessable. Except as described in
the Offering Memorandum, all the outstanding shares of capital stock of the
Company are owned of record by Holdings, free and clear of any security
interest, mortgage, pledge, lien, encumbrance or any pending or threatened
claim.

            (iv) The description of Holdings' stock option, stock bonus and
other stock plans or arrangements and the options or other rights granted
thereunder set forth in the Offering Memorandum fairly summarizes, in all
material respects, such plans, arrangements, options and rights.

            (v) The issuance and sale of the Notes by the Company will not be
subject to any preemptive right arising by operation of the charter or by-laws
of the Company or the General Corporation Law of the State of Delaware or under
any agreement listed on Schedule 1 hereto.

            (vi) The Purchase Agreement has been duly authorized, executed and
delivered by Holdings and the Company.

            (vii) Each of the Registration Rights Agreement and the DTC Letter
of Representations has been duly authorized, executed and delivered by, and is a
valid and binding agreement of, the Company, enforceable in accordance with its
terms, except with respect to any indemnification or contribution provision
thereof and subject to bankruptcy, insolvency, reorganization, moratorium,
fraudulent conveyance or other similar laws now or hereafter in effect relating
to creditors' rights and remedies and general principles of equity (regardless
of whether considered in a proceeding at law or in equity), and the Registration
Rights Agreement has been duly authorized, executed and delivered by, and is a
valid and binding agreement of, Holdings, enforceable in accordance with its
terms, except with respect to any indemnification or contribution provision
thereof and subject to bankruptcy, insolvency, reorganization, moratorium,
fraudulent conveyance or other similar laws now or hereafter in effect relating
to creditors' rights and remedies and general principles of equity (regardless
of whether considered in a proceeding at law or in equity).

            (viii) The Indenture has been duly authorized, executed and
delivered by the Company and Holdings and (assuming the due authorization,
execution and delivery thereof by the Trustee) constitutes a valid and binding
agreement of the Company and Holdings, enforceable against the Company and
Holdings in accordance with its terms, except with respect

                                      A-1
<PAGE>
to any indemnification or contribution provision thereof and subject to
bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or
other similar laws now or hereafter in effect relating to creditors' rights and
remedies and general principles of equity (regardless of whether considered in a
proceeding at law or in equity).

            (ix) The Notes are in the form contemplated by the Indenture, have
been duly authorized by the Company for issuance and sale pursuant to the
Purchase Agreement and the Indenture and, when executed by the Company and
authenticated by the Trustee in the manner provided in the Indenture (assuming
the due authorization, execution and delivery of the Indenture by the Trustee)
and delivered against surrender of the Existing Notes in exchange therefor (and,
in the case of the Additional Notes, payment of the purchase price therefor),
will constitute valid and binding obligations of the Company, enforceable
against the Company in accordance with their terms, except with respect to any
indemnification or contribution provision thereof and subject to bankruptcy,
insolvency, reorganization, moratorium, fraudulent conveyance or other similar
laws now or hereafter in effect relating to creditors' rights and remedies and
general principles of equity (regardless of whether considered in a proceeding
at law or in equity).

            (x) The Board of Directors of the Company has duly adopted by
requisite vote the resolutions necessary to authorize the execution, delivery
and performance of the Exchange Notes. No approval by Holdings, as sole
stockholder of the Company, is required therefor.

            (xi) The Guarantee by Holdings of the Notes is in the form
contemplated by the Indenture, has been duly authorized for issuance and sale
pursuant to the Purchase Agreement and the Indenture and, at the Closing Date,
will have been duly executed by Holdings and, when the Notes have been
authenticated in the manner provided for in the Indenture and delivered against
surrender of the Existing Notes in exchange therefor (and, in the case of the
Additional Notes, payment of the purchase price therefor), will constitute the
valid and binding agreement of Holdings, enforceable in accordance with its
terms, subject to bankruptcy, insolvency, reorganization, moratorium, fraudulent
conveyance or other similar laws now or hereafter in effect relating to
creditors' rights and remedies and general principles of equity (regardless of
whether considered in a proceeding at law or in equity), and will be entitled to
the benefits of the Indenture.

            (xii) The Securities, the Indenture and the Registration Rights
Agreement conform in all material respects to the descriptions thereof contained
in the Offering Memorandum.

            (xiii) The statements in the Offering Memorandum under the captions
"Offering Memorandum Summary -- The Acquisition and Related Financing
Transactions," "Risk Factors -- Risks Relating to the Notes -- Your right to
receive payments on these notes is junior to the issuer's existing senior
indebtedness and possibly all of its future borrowings. Further, the guarantees
of these notes are junior to all of the guarantors' existing senior indebtedness
and possibly to all their future borrowings," "Risk Factors -- Risks Relating to
the Notes -- Since the notes are unsecured, your right to enforce remedies is
limited by the rights of holders of secured debt," "Risk Factors -- Risks
Relating to the Notes -- You should not rely on our parent company's guarantee
in evaluating an investment in the notes," "Risk Factors -- Risks Relating to
the Notes -- Not all of our subsidiaries guarantee our obligations under the
notes, and the assets

                                      A-2
<PAGE>
of the non-guarantor subsidiaries may not be available to make payments on the
notes," "Risk Factors -- Risks Relating to the Notes -- The indenture related to
the notes and the new senior credit facilities will contain various covenants
which limit our management's discretion in the operations of our business,"
"Risk Factors -- Risks Relating to the Notes -- The issuer may not have the
ability to raise the funds necessary to finance the change of control offer
required by the indenture," "Risk Factors -- Risks Relating to the Notes --
Federal and state statutes allow courts, under specific circumstances, to avoid
guarantees and require noteholders to return payments received from guarantors,"
"Risk Factors -- Risks Relating to Our Company and Our Industry -- The interests
of our controlling stockholders could conflict with those of the holders of the
notes offered hereby," "The Acquisition and Related Financing Transactions,"
"Management -- Employment Agreements," "Management -- 2001 Stock Option Plan,"
"Management -- Stock Option Agreements," "Certain Relationships and Related
Transactions," "Description of New Senior Credit Facilities," "Description of
the Notes," "Certain Federal Income Tax Considerations" and "Notice to
Investors," insofar as such statements constitute matters of law, summaries of
legal matters, documents or legal conclusions, have been reviewed by such
counsel, fairly summarize, in all material respects, the matters referred to
therein and do not omit a material fact necessary to make the statements
contained therein not misleading.

            (xiv) No consent, approval, authorization or other order of, or
registration or filing with, any court or other governmental or regulatory
authority or agency of the federal government of the United States or the State
of New York, is required for the execution, delivery and performance by the
Company or any Guarantor of the Purchase Agreement, the Registration Rights
Agreement, the Indenture or the Securities, as applicable, the execution,
delivery and performance by the Company of the DTC Letter of Representations or
the issuance and delivery by the Company or any Guarantor of the Securities, or
consummation of the transactions contemplated hereby and thereby, except as may
be required under the Securities Act, the Exchange Act, the Trust Indenture Act
and applicable state securities or blue sky laws.

            (xv) The execution and delivery of the Purchase Agreement, the
Registration Rights Agreement, the DTC Letter of Representations, the Securities
and the Indenture by the Company and Holdings, to the extent it is a party
thereto, the performance by the Company and Holdings of their respective
obligations thereunder (i) will not result in any violation of the provisions of
the charter or by-laws of the Company or Holdings, as applicable, (ii) will not
constitute a breach of, or Default, or result in the imposition of any lien,
charge or encumbrance upon any property or assets of the Company or Holdings, as
applicable, pursuant to, with respect to the Company, any of the Agreements
listed on Schedule 1 hereto, and with respect to Holdings, any of the Agreements
listed on Schedule 2 hereto which Holdings has identified to us as its only
material agreements; or (iii) to the best knowledge of such counsel, will not
result in any violation of any law or administrative regulation, which a lawyer
exercising customary professional diligence would reasonably recognize as being
applicable to Holdings or the Company with respect to the transactions
contemplated by the Purchase Agreement, the Registration Rights Agreement, the
Indenture and the Securities. Such counsel need express no opinion herein as to
the applicability or effect of Healthcare Laws.

            (xvi) Neither the Company nor Holding is, nor after surrender of the
Existing Notes in exchange for the Notes (and receipt of payment for the
Additional Notes) will it be, an "investment company" requiring it to register
under the Investment Company Act.

                                      A-3
<PAGE>
            (xvii) Assuming the accuracy of the representations, warranties and
covenants of the Company, the Guarantors and the Initial Purchasers contained in
the Purchase Agreement, no registration of the Notes or the Guarantees under the
Securities Act, and no qualification of an indenture under the Trust Indenture
Act with respect thereto, is required in connection with the exchange of the
Existing Notes for the Securities (or, with respect to the Additional Notes, the
purchase thereof) by the Initial Purchasers or the initial resale of the
Securities by the Initial Purchasers to Qualified Institutional Buyers or
non-U.S. persons in the manner contemplated by the Purchase Agreement and the
Offering Memorandum other than any registration or qualification that may be
required in connection with the Exchange Offer contemplated by the Offering
Memorandum or in connection with the Registration Rights Agreement. Such counsel
need express no opinion, however, as to (x) the effect of state securities or
"blue sky" laws, foreign securities laws or the Exchange Act or (y) when or
under what circumstances any Notes initially sold by the Initial Purchasers may
be reoffered or resold.

            (xviii) To such counsel's knowledge, other than as described in the
Offering Memorandum, there are no pending or threatened legal or governmental
proceedings to which Holdings is a party that would be required to be described
by Item 103 of Regulation S-K under the Securities Act if the issuance of the
Notes were being registered under the Securities Act but is not so described in
the Offering Memorandum.

            (xix) None of the sale, issuance, execution or delivery of the Notes
will contravene Regulation T (12 C.F.R. Part 220), Regulation U (12 C.F.R. Part
221) or Regulation X (12 C.F.R. Part 224) of the Board of Governors of the
Federal Reserve System.

                                                                     EXHIBIT A-2

                      FORM OF OPINION OF HUNTON & WILLIAMS

            (i) Based solely on certificates of public officials and officers of
the Company, including the organizational documents attached thereto, the
Company is duly qualified as a foreign corporation to transact business and is
in good standing in each other jurisdiction in which such qualification is
required, whether by reason of the ownership or leasing of property or the
conduct of business, except for such jurisdictions where the failure to so
qualify or to be in good standing would not, individually or in the aggregate,
result in a Material Adverse Change.

            (ii) Based solely on certificates of public officials and officers
of the Company (which certificates shall be attached as exhibits to such
opinion), and the documents attached to such certificates (including the
organizational documents of the Subsidiary Guarantors), each Subsidiary
Guarantor is in valid existence and in good standing under the laws of its
respective jurisdiction of incorporation or formation as set forth on Schedule I
hereto. Based solely on certificates of public officials and officers of the
Company (which certificates shall be attached as exhibits to such opinion), and
the documents attached to such certificates (including the organizational
documents of the Subsidiary Guarantors), each Subsidiary Guarantor (a) has
corporate or entity power and authority to own, lease and operate its properties
and to conduct its business as described in the Offering Memorandum and to enter
into the Purchase Agreement and the other Transaction Documents to which it is a
party and (b) to the best of our knowledge, is duly qualified as a foreign
corporation or limited partnership, as the case may be, to transact business and
is in good standing in each jurisdiction in which such qualification is
required, whether by reason of the ownership or leasing of property or the
conduct of business, except for such jurisdictions where the failure to so
qualify or to be in good standing would not, individually or in the aggregate,
result in a Material Adverse Change.

            (iii) All of the issued and outstanding capital stock of each
Subsidiary Guarantor, if a corporation, has been duly authorized and, to our
knowledge, has been validly issued, is fully paid and non-assessable and is
owned by Holdings, directly or through Subsidiaries, free and clear of any
security interest, mortgage, pledge, lien, encumbrance or any pending or
threatened claim, except as disclosed in the Offering Memorandum.

            (iv) The Purchase Agreement has been duly authorized, executed and
delivered by each Subsidiary Guarantor.

            (v) The Registration Rights Agreement has been duly authorized,
executed and delivered by, and is a valid and binding agreement of, each
Subsidiary Guarantor, enforceable in accordance with its terms.

            (vi) The Indenture has been duly authorized, executed and delivered
by the each Subsidiary Guarantor and (assuming the due authorization, execution
and delivery thereof by the Trustee) constitutes a valid and binding agreement
of each Subsidiary Guarantor, enforceable against each Subsidiary Guarantor in
accordance with its terms.

            (vii) The Guarantees by the Subsidiary Guarantors of the Notes are
in the respective forms contemplated by the Indenture, have been duly authorized
for issuance and sale pursuant

                                      A-5
<PAGE>
to the Purchase Agreement and the Indenture and have been duly executed by each
of the Subsidiary Guarantors and, assuming the Notes have been authenticated in
the manner provided for in Section 2.02 of the Indenture and delivered against
surrender of the Existing Notes in exchange therefor (and, in the case of the
Additional Notes, assuming the payment of the purchase price therefor), will
constitute the valid and binding agreement of each Subsidiary Guarantor,
enforceable in accordance with its terms and will be entitled to the benefits of
the Indenture.

            (viii) The documents incorporated by reference in the Offering
Memorandum (other than the financial statements and related notes thereto and
other financial, statistical and accounting data and supporting schedules
therein, as to which no opinion need be rendered), when they were filed with the
Commission, complied as to form in all material respects with the requirements
of the Exchange Act.

            (ix) To such counsel's knowledge, there are no pending or threatened
legal or governmental proceedings to which the Company or any of its
subsidiaries is a party that would be required to be described by Item 103 of
Regulation S-K under the Securities Act if the issuance of the Notes were being
registered under the Securities Act but is not so described in the Offering
Memorandum.

            The enforceability of the Registration Rights Agreement, the
Indenture and the Guarantees of the Notes by the Subsidiary Guarantors is
subject to (i) bankruptcy, insolvency, reorganization, moratorium, fraudulent
conveyance or other laws affecting the rights of creditors generally, and (ii)
general principles of equity, whether considered at law or in equity. We express
no opinion with respect to the indemnification and contribution provisions
contained in the Registration Rights Agreement and the Indenture.

            We have participated in various conferences with the officers and
other representatives of the Company and its independent certified public
accountants. In some conferences you and your counsel also participated. At
those conferences, the contents of the Offering Memorandum and Prospectus were
discussed and revised. Since the dates of those conferences, we have inquired of
certain officers whether there has been any material change in the affairs of
the Company.

Because of the inherent limitations in the independent verification of factual
matters, and the character of determinations involved in the preparation of
offering memoranda under the Securities Act, we are not passing upon, and do not
assume any responsibility for, and make no representation that we have
independently verified, the accuracy, completeness or fairness of the statements
contained in the Offering Memorandum. Also, we do not express any opinion or
belief as to the financial statements or other financial and statistical
information contained in the Offering Memorandum, or derived therefrom, or
incorporated therein by reference. However, subject to the foregoing, on the
basis of our participation in the conferences referred to above and our
examination of the documents referred to herein, we advise you that nothing has
come to the attention of the attorneys of this firm who have been engaged in the
representation of the Company in connection with the Company's issuance and sale
of the Notes that leads us to believe that the Offering Memorandum, as of its
date or at the Closing Date, contained or contains an untrue statement of
material fact or omitted or omits to state a material fact necessary

<PAGE>
violation of the provisions of the limited partnership agreement, charter or
by-laws of the Company or any Subsidiary Guarantor, as applicable, or (ii) will
not constitute a breach of, or Default under or result in the imposition of any
lien, charge or encumbrance upon any property or assets of the Company or any
Subsidiary Guarantor pursuant to (x) any contract, loan agreement, note
indenture, mortgage, deed of trust, lease or other agreement or instrument filed
by the Company with the Commission (other than the agreements listed on Schedule

any of the Subsidiary Guarantors is in violation of its charter or by-laws or
equivalent constitutive document or any law, administrative regulation or
administrative or court decree applicable to it or is in Default in the
performance or observance of any obligation, agreement, covenant or condition
contained in any agreement listed as an Exhibit to the Annual Report or in

   In addition, such counsel shall state that such counsel has participated in
conferences with officers and other representatives of Acquisition and the
Company, representatives of the independent public or certified public
accountants for the Company and with representatives of the Initial Purchaser at
which the contents of the Offering Memorandum, and any supplements or amendments
thereto, and related matters were discussed and revised and, although such
counsel is not passing upon and does not assume any responsibility for, and
makes no representation that such counsel has independently verified, the
accuracy, completeness or fairness of the statements contained in the Offering
Memorandum (other than as specified above), and any supplements or amendments
thereto, subject to the foregoing, no facts have come to such counsel's
attention which would lead such counsel to believe that either the Offering
Memorandum, as of its date or at the Closing Date, contained or contains an
untrue statement of a material fact or omitted or omits to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading (it being understood
that such counsel need express no belief as to the financial statements or other
financial or statistical data derived therefrom, included or incorporated by
reference in the Offering Memorandum or any amendments or supplements thereto).
