Dear Sirs:

     1.  Introductory.  Laboratory Corporation of America Holdings, a Delaware
corporation (the "Company"), proposes, subject to the terms and conditions
stated herein, to issue and sell to the several initial purchasers named in
Schedule A hereto (the "Purchasers") U.S.$350,000,000 principal amount of
its 5 1/2% Senior Notes due February 1, 2013 ("Offered Securities") to be
issued under an indenture dated as of January 31, 2003  (the "Indenture"),
between the Company and Wachovia Bank, National Association, as Trustee on a
private placement basis pursuant to an exemption under Section 4(2) of the
United States Securities Act of 1933 (the "Securities Act"), and hereby agrees
with the several Purchasers as follows:

     The holders of the Offered Securities will be entitled to the benefits
of a Registration Rights Agreement of even date herewith among the Company
and the Purchasers (the "Registration Rights Agreement"), pursuant to which
the Company agrees to file a registration statement with the Securities
Exchange Commission (the "Commission") registering the issuance of Exchange
Securities (as defined herein) in exchange for the Offered Securities or,
under the circumstances described herein, the resale of the Offered
Securities under the Securities Act.

     2.  Representations and Warranties of the Company.  The Company
represents and warrants to, and agrees with, the several Purchasers that:

           (a)  A preliminary offering circular and an offering circular
     relating to the Offered Securities have been prepared by the Company.
     Such preliminary offering circular (the "Preliminary Offering Circular")
     and offering circular (the "Offering Circular"), as supplemented as of
     the date of this Agreement, together with the documents incorporated
     therein by reference and any other document approved by the Company for
     use in connection with the contemplated resale of the Offered Securities,
     are hereinafter collectively referred to as the "Offering Document".  On
     the date of this Agreement, the Offering Document does not include any
     untrue statement of a material fact or omit to state any material fact
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading.  The preceding
     sentence does not apply to statements in or omissions from the Offering
     Document based upon written information furnished to the Company by any
     Purchaser through Credit Suisse First Boston LLC ("CSFB") specifically
     for use therein, it being understood and agreed that the only such
     information is that described as such in Section 7(b) hereof.  Except
     as disclosed in the Offering Document, on the date of this Agreement,
     the Company's Annual Report on Form 10-K most recently filed with the
     Commission and all subsequent reports (collectively, the "Exchange Act
     Reports") which have been filed by the Company with the Commission or
     sent to shareholders pursuant to the Securities Exchange Act of 1934
     (the "Exchange Act"), taken together, do not include any untrue statement
     of a material fact or omit to state any material fact necessary to make
     the statements therein, in the light of the circumstances under which
     they were made, not misleading.  Such documents, when they were filed
     with the Commission, conformed in all material respects to the
     requirements of the Exchange Act and the rules and regulations of the
     Commission thereunder.

           (b)  [intentionally deleted]

           (c)  The Company has been duly incorporated and is an existing
     corporation in good standing under the laws of the State of Delaware,
     with power and authority (corporate and other) to own its properties and
     conduct its business as described in the Offering Document; and the
     Company is duly qualified to do business as a foreign corporation in good
     standing in all other jurisdictions in which its ownership or lease of
     property or the conduct of its business requires such qualification,
     except where the failure to be so qualified individually or in the
     aggregate would not have a material adverse effect on the business,
     financial condition, properties or results of operations of the Company
     and its subsidiaries taken as a whole (a "Material Adverse Effect").

           (d)  Each subsidiary of the Company has been duly incorporated and
     is an existing corporation in good standing under the laws of the
     jurisdiction of its incorporation, with power and authority (corporate
     and other) to own its properties and conduct its business as described
     in the Offering Document; and each subsidiary of the Company is duly
     qualified to do business as a foreign corporation in good standing in
     all other jurisdictions in which its ownership or lease of property or
     the conduct of its business requires such qualification, except where
     the failure to be so qualified individually or in the aggregate would
     not have a Material Adverse Effect; all of the issued and outstanding
     capital stock of each subsidiary of the Company has been duly authorized
     and validly issued and is fully paid and nonassessable; and the capital
     stock of each subsidiary owned by the Company, directly or through
     subsidiaries, is owned free from liens, encumbrances and defects.

           (e)  The Indenture has been duly authorized; the Offered Securities
     have been duly authorized; and assuming due authorization, execution and
     delivery of the Indenture and authentification of the Offered Securities,
     in accordance with the Indenture, by the Trustee, when the Offered
     Securities are delivered and paid for pursuant to this Agreement on the
     Closing Date (as defined below), the Indenture will have been duly
     executed and delivered, such Offered Securities will have been duly
     executed, authenticated, issued and delivered and will conform to the
     description thereof contained in the Offering Document; and the Indenture
     and such Offered Securities will constitute valid and legally binding
     obligations of the Company, enforceable in accordance with their terms,
     subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
     moratorium and similar laws of general applicability relating to or
     affecting creditors' rights and to general equity principles.

           (f)  No consent, approval, authorization, or order of, or filing
     with, any governmental agency or body or any court is required for the
     consummation of the transactions contemplated by this Agreement and the
     Registration Rights Agreement in connection with the issuance and sale
     of the Offered Securities by the Company, except for the filing of the
     Exchange Offer Registration or the Shelf Registration Statement (each as
     defined in the Registration Rights Agreement) and the order of the
     Commission declaring such registration statement effective and such
     consents, approvals, authorizations, orders or filings under state
     securities or Blue Sky laws that the failure to obtain would not
     individually or in the aggregate (i) have a Material Adverse Effect or
     (ii) adversely affect in a material respect the ability of the Company
     to perform its obligations under the Indenture, this Agreement or the
     Registration Rights Agreement, or would otherwise be material in the
     context of the sale of the Offered Securities.

           (g)  The execution, delivery and performance of the Indenture, this
     Agreement, the Registration Rights Agreement, and the issuance and sale
     of the Offered Securities and compliance with the terms and provisions
     thereof will not result in a breach or violation of any of the terms and
     provisions of, or constitute a default under, (i) any statute, any rule,
     regulation or order of any governmental agency or body or any court,
     domestic or foreign, having jurisdiction over the Company or any
     subsidiary of the Company or any of their properties, or (ii) any
     agreement or instrument to which the Company or any such subsidiary is
     a party or by which the Company or any such subsidiary is bound or to
     which any of the properties of the Company or any such subsidiary is
     subject, or (iii) the charter or by-laws of the Company or any such
     subsidiary, and the Company has full power and authority to authorize,
     issue and sell the Offered Securities as contemplated by this Agreement,
     except in the case of clause (i) or (ii), any such breach, violation or
     default that would not (x) individually or in the aggregate have a
     Material Adverse Effect or (y) prevent the consummation of the
     transactions contemplated by this Agreement and the Registration Rights
     Agreement in connection with the issuance and sale of the Offered
     Securities by the Company.

           (h)  This Agreement and the Registration Rights Agreement have been

     and all other properties and assets owned by them, in each case free

     aggregate would have a Material Adverse Effect or materially interfere
     with the use made or to be made thereof by them; and except as disclosed
     in the Offering Document, the Company and its subsidiaries hold any
     leased real or personal property under valid and enforceable leases with
     no exceptions that would materially interfere with the use made or to be

     would individually or in the aggregate have a Material Adverse Effect.

           (k)  No labor dispute with the employees of the Company or any

     presently employed by them, and have not received any notice of
     infringement of or conflict with asserted rights of others with respect

     sale of the Offered Securities by the Company to the several Purchasers

     or supplement the Offering Document and will not effect such amendment
     or supplementation without CSFB's consent.  If, at any time prior to the
     completion of the resale of the Offered Securities by the Purchasers any
     event occurs as a result of which the Offering Document as then amended
     or supplemented would include an untrue statement of a material fact or
     omit to state any material fact necessary in order to make the statements
     therein, in the light of the circumstances under which they were made,
     not misleading, the Company promptly will notify CSFB of such event and
     promptly will prepare, at its own expense, an amendment or supplement
     which will correct such statement or omission.  Neither CSFB's consent
     to, nor the Purchasers' delivery to offerees or investors of, any such
     amendment or supplement shall constitute a waiver of any of the
     conditions set forth in Section 6.

           (b)  The Company will furnish to CSFB copies of any preliminary
     offering circular, the Offering Document and all amendments and
     supplements to such documents, in each case as soon as available and in
     such quantities as CSFB requests, and the Company will furnish to CSFB on
     the date hereof three copies of the Offering Document signed by a duly
     authorized officer of the Company, one of which will include the
     independent accountants' reports therein manually signed by such
    independent accountants.  At any time when the Company is not subject to
     Section 13 or 15(d) of the Exchange Act, the Company will promptly
     furnish or cause to be furnished to CSFB (and, upon request, to each of
     the other Purchasers) and, upon request of holders and prospective
     purchasers of the Offered Securities, to such holders and purchasers,
     copies of the information required to be delivered to holders and
     prospective purchasers of the Offered Securities pursuant to Rule
     144A(d)(4) under the Securities Act (or any successor provision thereto)
     in order to permit compliance with Rule 144A in connection with resales
     by such holders of the Offered Securities.  The Company will pay the
     expenses of printing and distributing to the Purchasers all such
     documents.

           (c)  The Company will use its best efforts to arrange for the
     qualification of the Offered Securities for sale and the determination of
     their eligibility for investment under the laws of such states in the
     United States as CSFB designates and will continue such qualifications in
     effect so long as required for the resale of the Offered Securities by
     the Purchasers provided that the Company will not be required to qualify
     as a foreign corporation or to file a general consent to service of
     process in any such state.

           (d)  During the period of two years after the Closing Date, the
     Company will, upon request, furnish to CSFB, each of the other Purchasers
     and any holder of Offered Securities a copy of the restrictions on
     transfer applicable to the Securities.

           (e)  During the period of two years after the Closing Date, the
     Company will not, and will not permit any of its affiliates (as defined
     in Rule 144 under the Securities Act) to, resell any of the Offered
     Securities that have been reacquired by any of them otherwise than
     pursuant to an effective registration statement under the Securities Act.

           (f)  During the period of two years after the Closing Date, the
     Company will not be or become, an open-end investment company, unit
     investment trust or face-amount certificate company that is or is
     required to be registered under Section 8 of the Investment Company Act.

           (g)  The Company will pay all expenses incidental to the
     performance of its obligations under this Agreement, the Indenture and
     the Registration Rights Agreement  including (i) the fees and expenses
     of the Trustee and its professional advisers; (ii) all expenses in
     connection with the execution, issue, authentication, packaging and
     initial delivery of the Offered Securities and, as applicable, the
     Exchange Securities (as defined in the Registration Rights Agreement),
     the preparation and printing of this Agreement, the Registration Rights
     Agreement, the Offered Securities, the Indenture, the Offering Document
     and amendments and supplements thereto, and any other document relating
     to the issuance, offer, sale and delivery of the Offered Securities, and
     as applicable, the Exchange Securities; (iii) the cost of qualifying the
     Offered Securities for trading in The PortalSM Market ("PORTAL") of The
     Nasdaq Stock Market, Inc. and any expenses incidental thereto, (iv) the
     cost of any advertising approved by the Company in connection with the
     issue of the Offered Securities, (v) any expenses (including fees and
     disbursements of counsel) incurred in connection with qualification of
     the Offered Securities or the Exchange Securities for sale under the
     laws of such jurisdictions as CSFB designates and the printing of
     memoranda relating thereto, (vi) any fees charged by investment rating
     agencies for the rating of the Securities or the Exchange Securities,
     and (vii) expenses incurred in distributing preliminary offering
     circulars and the Offering Document (including any amendments and
     supplements thereto) to the Purchasers.  The Company will reimburse the
     Purchasers for all expenses of the Purchasers and the Company in
     connection with attending or hosting meetings with prospective
     purchasers of the Offered Securities.

           (h)  In connection with the offering, until CSFB shall have
     notified the Company and the other Purchasers of the completion of the
     resale of the Offered Securities, neither the Company nor any of its
     affiliates has or will, either alone or with one or more other persons,
     bid for or purchase for any account in which it or any of its affiliates
     has a beneficial interest any Offered Securities or attempt to induce any
     person to purchase any Offered Securities; and neither it nor any of its
     affiliates will make bids or purchases for the purpose of creating
     actual, or apparent, active trading in, or of raising the price of, the
     Offered Securities.

           (i)  For a period of 30 days after the date of the initial offering
     of the Offered Securities by the Purchasers, the Company will not offer,
     sell, contract to sell, pledge, or otherwise dispose of, directly or
     indirectly, any debt securities issued or guaranteed by the Company and
     having a maturity of more than one year from the date of issue.  The
     Company will not at any time offer, sell, contract to sell, pledge or
     otherwise dispose of, directly or indirectly, any securities under
     circumstances where such offer, sale, pledge, contract or disposition
     would cause the exemption afforded by Section 4(2) of the Securities Act
     or the safe harbor of Regulation S thereunder to cease to be applicable
     to the offer and sale of the Offered Securities.

     6.  Conditions of the Obligations of the Purchasers.  The obligations of
the several Purchasers to purchase and pay for the Offered Securities will be
subject to the accuracy of the representations and warranties on the part of
the Company herein, to the accuracy of the statements of officers of the
Company made pursuant to the provisions hereof, to the performance by the
Company of its obligations hereunder and to the following additional
conditions precedent:

           (a)  The Purchasers shall have received a letter, dated the date of
     this Agreement, of PricewaterhouseCoopers LLP confirming that they are
     independent public accountants within the meaning of the Securities Act
     and the applicable published rules and regulations thereunder ("Rules and
     Regulations") and to the effect that:

                (i) In their opinion the financial statements and schedules
           examined by them and included in the Offering Document and in the
           Exchange Act Reports comply as to form in all material respects
           with the applicable accounting requirements of the Securities Act
           and the related published Rules and Regulations;

               (ii) they have performed the procedures specified by the
           American Institute of Certified Public Accountants for a review of
           interim financial information as described in Statement of Auditing
           Standards No. 71, Interim Financial Information, on the unaudited
           financial statements included in the Offering Document and in the
           Exchange Act Reports;

              (iii) on the basis of the review referred to in clause (ii)
           above, a reading of the latest available interim financial
           statements of the Company, inquiries of officials of the Company
           who have responsibility for financial and accounting matters and
           other specified procedures, nothing came to their attention that
           caused them to believe that:

                          (A) the unaudited financial statements included in
                    the Offering Document or in the Exchange Act Reports do
                    not comply as to form in all material respects with the
                    applicable accounting requirements of the Securities Act
                    and the related published Rules and Regulations or any
                    material modifications should be made to such unaudited
                    financial statements for them to be in conformity with
                    generally accepted accounting principles;

                          (B) the unaudited consolidated net sales, net
                    operating income, net income and net income per share
                    amounts for the nine-month periods ended September 30,
                    2001, and September 30, 2002, included in the Offering
                    Document do not agree with the amounts set forth in the
                    unaudited consolidated financial statements for those same
                    periods or were not determined on a basis substantially
                    consistent with that of the corresponding amounts in the
                    audited statements of income;

                          (C) at the date of the latest available balance
                    sheet read by such accountants, or at a subsequent
                    specified date not more than three business days prior to
                    the date of this Agreement, there was any change in the
                    capital stock or any increase in short-term indebtedness
                    or long-term debt of the Company and its consolidated
                    subsidiaries or, at the date of the latest available
                    balance sheet read by such accountants, there was any
                    decrease in consolidated net current assets or net assets,
                    as compared with amounts shown on the latest balance sheet
                    included in the Offering Document; or

                          (D) for the period from the closing date of the
                    latest income statement included in the Offering Document
                    to the closing date of the latest available income
                    statement read by such accountants there were any
                    decreases, as compared with the corresponding period of
                    the previous year and with the period of corresponding
                    length ended the date of the latest income statement
                    included in the Offering Document, in consolidated net
                    sales, net operating income consolidated income before
                    extraordinary items or net income or in the ratio of
                    earnings to fixed charges; except in all cases set forth
                    in clauses (B) and (C) above for changes, increases or
                    decreases which the Offering Document disclose have
                    occurred or may occur or which are described in such
                    letter; and

                          (iv) they have compared specified dollar amounts (or
                    percentages derived from such dollar amounts) and other
                    financial information contained in the Offering Document
                    and the Exchange Act Reports (in each case to the extent
                    that such dollar amounts, percentages and other financial
                    information are derived from the general accounting
                    records of the Company and its subsidiaries subject to the
                    internal controls of the Company's accounting system or
                    are derived directly from such records by analysis or
                    computation) with the results obtained from inquiries, a
                    reading of such general accounting records and other
                    procedures specified in such letter and have found such
                    dollar amounts, percentages and other financial information
                    to be in agreement with such results, except as otherwise
                    specified in such letter.

                          (v) on the basis of a reading of the pro forma
                    financial statements, carrying out certain specified
                    procedures, reading of minutes, inquiries of certain
                    officials of the Company who have responsibility for
                    financial and accounting matters and proving the
                    arithmetic accuracy of the application of the pro forma
                    adjustments to the historical amounts in the pro forma
                    consolidated financial statements, nothing came to their
                    attention which caused them to believe that the pro forma
                    financial statements do not comply as to form in all
                    material respects with the applicable accounting
                    requirements of Rule 11-02 of Regulation S-X under the
                    Securities Act or that the pro forma adjustments have not
                    been properly applied to the historical amounts in the
                    compilations of such statements or on the pro forma basis
                    described in the notes thereto.

           (b)  Subsequent to the execution and delivery of this Agreement,
     there shall not have occurred (i) any change, or any development or event
     involving a prospective change, in the condition (financial or other),
     business, properties or results of operations of the Company and its
     subsidiaries taken as one enterprise which, in the judgment of a majority
     in interest of the Purchasers, including CSFB, is material and adverse
     and makes it impractical or inadvisable to proceed with completion of the
     offering or the sale of and payment for the Offered Securities on the
     terms and in the manner described in the Offering Document; (ii) any
     downgrading in the rating of any debt securities of the Company by any
     "nationally recognized statistical rating organization" (as defined for
     purposes of Rule 436(g) under the Securities Act), or any public
     announcement that any such organization has under surveillance or review
     its rating of any debt securities of the Company (other than an
     announcement with positive implications of a possible upgrading, and no
     implication of a possible downgrading, of such rating); (iii) any change
     in U.S. or international financial, political or economic conditions or
     currency exchange rates or exchange controls as would, in the judgment of
     a majority in interest of the Purchasers including CSFB, be likely to
     prejudice materially the success of the proposed issue, sale or
     distribution of the Offered Securities, whether in the primary market or
     in respect of dealings in the secondary market; (iv) any material
     suspension or material limitation of trading in securities generally on
     the New York Stock Exchange or any setting of minimum prices for trading
     on such exchange, or any suspension of trading of any securities of the
     Company on any exchange or in the over-the-counter market; (v) any
     banking moratorium declared by U.S. Federal or, New York authorities;
     (vi) any major disruption of settlements of securities or clearance
     services in the United States or (vii) any attack on, outbreak or
     escalation of hostilities or act of terrorism involving the United
     States, any declaration of war by Congress or any other national or
     international calamity or emergency if, in the judgment of a majority in
     interest of the Purchasers including CSFB, the effect of any such attack,
     outbreak, escalation, act, declaration, calamity or emergency makes it
     impractical or inadvisable to proceed with completion of the offering or
     sale of and payment for the Offered Securities on the terms and in the
     manner described in the Offering Document.

           (c)  The Purchasers shall have received an opinion, dated such
     Closing Date, of Hogan & Hartson L.L.P., counsel for the Company, that:

                (i) The Company is validly existing as a corporation and in
           good standing under the laws of the State of Delaware.

                (ii) The Company has the corporate power to execute, deliver
           and perform this Agreement, the Indenture and the Registration
           Rights Agreement.  The execution, delivery and performance by the
           Company of this Agreement, the Indenture and the Registration
           Rights Agreement have been duly authorized by all necessary
           corporate action of the Company.

                (iii) The Indenture has been duly authorized, executed and
           delivered by the Company and constitutes a valid and legally
           binding instrument, enforceable in accordance with its terms.

                (iv) The Offered Securities have been duly authorized and
           executed by the Company and, assuming due authentication by the
           Trustee and payment therefor, are duly  issued and delivered by the
           Company and constitute valid and legally binding obligations of the
           Company entitled to the benefits of the Indenture and enforceable
           against the Company in accordance with their terms.

                (v) This Agreement and the Registration Rights Agreement have
           been duly executed and delivered on behalf of the Company.

                (vi) The execution, delivery and performance by the Company of
           this Agreement, the Indenture and the Registration Rights Agreement
           do not (i) require any approval of its stockholders which has not
           been obtained, (ii) violate the General Corporation Law of the
           State of Delaware, as amended, or the Certificate of Incorporation
           of the Company or the Bylaws of the Company, (iii) violate any
           federal statute or regulation covered by such letter, or (iv) to
           the best of such counsel's knowledge, violate any court or
           administrative order, judgment or decree that names the Company and
           is specifically directed to it or any of its property.

                (vii) Based upon and assuming the accuracy of the
           representations and warranties, and assuming due performance of the
           covenants and agreements, of the Company and the Purchasers
           contained in this Agreement, it is not necessary in connection with
           the offer, sale and delivery of the Offered Securities to the
           Purchasers under this Agreement, or in connection with the initial
           resale of the Offered Securities in accordance with this Agreement
           and the Offering Document, to register the Offered Securities under
           the Securities Act of 1933 or to qualify the Indenture under the
           Trust Indenture Act of 1939; it being understood that no opinion
           need be expressed as to any resale of an Offered Security
           subsequent to such initial resale thereof by the Purchasers.

                (viii) The Offered Securities conform to the summary of the
           terms thereof contained in the Offering Document under the caption
           "Description of the Notes".

                (ix) In addition to the matters set forth above, such letter
           shall also contain a statement of such counsel to the effect that:
           while counsel does not assume any responsibility for the accuracy,
           completeness or fairness of the statements in the Offering
           Document, no facts have come to such counsel's attention which have
           resulted in such counsel having concluded that the Offering
           Document, as of its date and as of the Closing Date, contained an
           untrue statement of a material fact or omitted to state a material
           fact necessary to make the statements therein not misleading;
           provided that in making the foregoing statements (which shall not
           constitute an opinion), such counsel need not express any views as
           to the financial statements and supporting schedules and other
           financial information and data included in or omitted from the
           Offering Document.

           (d)  The Purchasers shall have received an opinion, dated such
     Closing Date, of  David P. King, General Counsel of the Company, that:

                (i) The Company and each subsidiary (a) is duly organized,
           validly existing and in good standing under the laws of the
           jurisdiction of its organization, (b) has all requisite power and
           authority to own its property and assets and to carry on its
           business as described in the Offering Document and (c) is qualified
           to do business in, and is in good standing in, every jurisdiction
           where such qualification is required, except where the failure so
           to qualify could not reasonably be expected to result in a Material
           Adverse Effect.  All of the issued and outstanding capital stock of
           each subsidiary of the Company has been duly authorized and validly
           issued and is fully paid and nonassessable; and the capital stock
           of each subsidiary owned by the Company, directly or through
           subsidiaries, is owned free from liens, encumbrances and defects.

                (ii) The execution, delivery and performance of this
           Agreement, the Indenture and the Registration Rights Agreement by
           the Company (a) have been duly authorized by all requisite
           corporate and, if required, stockholder action of the Company and
           (b) will not (i) violate (A) any provision of law, statute, rule or
           regulation of the United States of America or the Delaware General
           Corporation Law or of the certificate or articles of incorporation
           or other constitutive documents or by-laws of the Company or any
           subsidiary, (B) any order of any Governmental Authority or (C) any
           provision of any indenture, agreement or other instrument to which
           the Company or any subsidiary is a party or by which any of them or
           any of their property is bound, the effect of which could
           reasonably be expected to result in a Material Adverse Effect or
           would adversely affect the ability of the Company to perform its
           obligations under the Indenture, this Agreement or the Registration
           Rights Agreement, or would otherwise be material in the context of
           the sale of the Offered Securities, (ii) result in a breach of or
           constitute (alone or with notice or lapse of time or both) a
           default under, or give rise to any right to accelerate or to
           require the prepayment, repurchase or redemption of any obligation
           under any such indenture, agreement or other instrument, the effect
           of which could reasonably be expected to result in a Material
           Adverse Effect or would adversely affect the ability of the Company
           to perform its obligations under the Indenture, this Agreement or
           the Registration Rights Agreement, or would otherwise be material
           in the context of the sale of the Offered Securities or (iii)
           result in the creation or imposition of any Lien upon or with
           respect to any property or assets now owned by the Company or any
           subsidiary.

                (iii) No action, consent or approval of, registration or
           filing with or any other action by any United States federal
           Governmental Authority, or to the extent required under state law,
           any state Governmental Authority, is required for the due
           execution, delivery and performance by the Company of this
           Agreement, the Indenture or the Registration Rights Agreement,
           except for the filing of the Exchange Offer Registration Statement
           or the Shelf Registration Statement and the order of the Commission
           declaring such registration statement effective.

                (iv) There are not any actions, suits or proceedings at law or
           in equity or by or before any Governmental Authority now pending or
           threatened or, to the best of such counsel's knowledge
           contemplated, against or affecting the Company or any Subsidiary
           that, if adversely determined, could reasonably be expected,
           individually or in the aggregate, to result in a Material Adverse
           Effect or would materially and adversely affect the ability of the
           Company to perform its obligations under the Indenture, this
           Agreement or the Registration Rights Agreement or which are
           otherwise material in the context of the sale of the Offered
           Securities.

                (v) The descriptions in the Offering Document of statutes,
           legal and governmental proceedings and contracts and other
           documents are accurate and fairly present the information required
           to be shown.

           (e)  The Purchasers shall have received from Cravath, Swaine &
     Moore, counsel for the Purchasers, such opinion or opinions, dated the
     Closing Date, with respect to the incorporation of the Company, the
     validity of the Offered Securities and the Offering Circular, the
     exemption from registration for the offer and sale of the Offered
     Securities by the Company to the several Purchasers and the resales by
     the several Purchasers as contemplated hereby and other related
     matters as CSFB may require, and the Company shall have furnished to
     such counsel such documents as they request for the purpose of enabling
     them to pass upon such matters.

           (f)  The Purchasers shall have received a certificate, dated the
     Closing Date, of the President or any Vice President and a principal
     financial or accounting officer of the Company in which such officers, to
     the best of their knowledge after reasonable investigation, shall state
     that the representations and warranties of the Company in this Agreement
     are true and correct, that the Company has complied with all agreements
     and satisfied all conditions on its part to be performed or satisfied
     hereunder at or prior to the date of the most recent financial statements
     in the Offering Document there has been no material adverse change, nor
     any development or event involving a prospective material adverse change,
     in the financial condition, business, properties or results of operations
     of the Company and its subsidiaries taken as a whole except as set forth
     in or contemplated by the Offering Document or as described in such
     certificate.

           (g)  The Purchasers shall have received a letter, dated the Closing
     Date, of PricewaterhouseCoopers LLP which meets the requirements of
     subsection (a) of this Section, except that the specified date referred
     to in such subsection will be a date not more than three days prior to
     the Closing Date for the purposes of this subsection.The Company will
     furnish the Purchasers with such conformed copies of such opinions,
     certificates, letters and documents as the Purchasers reasonably request.
     CSFB may in its sole discretion waive on behalf of the Purchasers
     compliance with any conditions to the obligations of the Purchasers
     hereunder.

     7.  Indemnification and Contribution.  (a)  The Company will indemnify
and hold harmless each Purchaser, its partners, directors and officers and
each person, if any, who controls such Purchaser within the meaning of Section
15 of the Securities Act, against any losses, claims, damages or liabilities,
joint or several, to which such Purchaser may become subject, under the
Securities Act or the Exchange Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of any
material fact contained in the Offering Document, or any amendment or
supplement thereto, or any related preliminary offering circular or the
Exchange Act Reports, or arise out of or are based upon the omission or
alleged omission to state therein a material fact necessary in order to make
the statements therein, in light of the circumstances under which they were
made, not misleading, including any losses, claims, damages or liabilities
arising out of or based upon the Company's failure to perform its obligations
under Section 5(a) of this Agreement, and will reimburse each Purchaser for
any legal or other expenses reasonably incurred by such Purchaser in
connection with investigating or defending any such loss, claim, damage,
liability or action as such expenses are incurred; provided, however, that
the Company will not be liable in any such case to the extent that any such
loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement in or omission or alleged omission from
any of such documents in reliance upon and in conformity with written
information furnished to the Company by any Purchaser through CSFB
specifically for use therein, it being understood and agreed that the only such
information consists of the information described as such in subsection (b)
below; and provided, further, that with respect to any untrue statement or
alleged untrue statement in, or omission or alleged omission from, any
preliminary offering circular, the indemnity agreement contained in this
subsection (a) shall not inure to the benefit of any Purchaser that sold the
Offered Securities concerned to the person asserting any such losses, claims,
damages or liabilities, to the extent that such sale was an initial resale by
such Purchaser and any such loss, claim, damage or liability of such Purchaser
results from the fact that there was not sent or given to such person, at or
prior to the written confirmation of the sale of such Offered Securities to
such person, a copy of the Offering Document (exclusive of any material
included therein but not attached thereto) if the Company had previously
furnished copies thereof to such Purchaser.

      (b)  Each Purchaser will severally and not jointly indemnify and hold
harmless the Company, its directors and officers and each person, if any, who
controls the Company within the meaning of Section 15 of the Securities Act,
against any losses, claims, damages or liabilities to which the Company may
become subject, under the Securities Act or the Exchange Act or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact contained in the Offering Document, or any
amendment or supplement thereto, or any related preliminary offering circular,
or arise out of or are based upon the omission or the alleged omission to
state therein a material fact 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 reliance upon and in conformity with written information
furnished to the Company by such Purchaser through CSFB specifically for use
therein, and will reimburse any legal or other expenses reasonably incurred by
the Company in connection with investigating or defending any such loss,
claim, damage, liability or action as such expenses are incurred, it being
understood and agreed that the only such information furnished by any
Purchaser consists of the following information in the Offering Document
furnished on behalf of each Purchaser: (i) the over-allotment and stabilizing
descriptions appearing in the ninth paragraph under the caption "Plan of
Distribution" and (ii) the following information in the Offering Document
furnished on behalf of the Purchasers: the information appearing in the tenth
paragraph under the caption "Plan of Distribution"; provided however, that the
Purchasers shall not be liable for any losses, claims, damages or liabilities
arising out of or based upon the Company's failure to perform its obligations
under Section 5(a) of this Agreement.

      (c)  Promptly after receipt by an indemnified party under this Section
of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under
subsection (a) or (b) above, notify the indemnifying party of the commencement
thereof; but the failure to notify the indemnifying party shall not relieve it
from any liability that it may have under subsection (a) or (b) above except
to the extent that it has been materially prejudiced (through the forfeiture
of substantive rights or defenses) by such failure; and provided further
that the failure to notify the indemnifying party shall not relieve it from
any liability that it may have to an indemnified party otherwise than under
subsection (a) or (b) above.  In case any such action is brought against any
indemnified party and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate therein and,
to the extent that it may wish, jointly with any other indemnifying party
similarly notified, to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified party (who shall not, except with the consent
of the indemnified party, be counsel to the indemnifying party), and after
notice from the indemnifying party to such indemnified party of its election
so to assume the defense thereof, the indemnifying party will not be liable to
such indemnified party under this Section for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof other than reasonable costs of investigation.  No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened action in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party unless such settlement includes
(i) an unconditional release of such indemnified party from all liability on
any claims that are the subject matter of such action and (ii) does not
include a statement as to or an admission of fault or failure to act by
or on behalf of any indemnified party.

      (d)  If the indemnification provided for in this Section is unavailable
or insufficient to hold harmless an indemnified party under subsection (a) or
(b) above, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of the losses, claims, damages
or liabilities referred to in subsection (a) or (b) above (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company on the one hand and the Purchasers on the other from the offering of
the Offered Securities or (ii) if the allocation provided by clause (i) above
is not permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause (i) above but
also the relative fault of the Company on the one hand and the Purchasers on
the other in connection with the statements or omissions which resulted in
such losses, claims, damages or liabilities as well as any other relevant
equitable considerations.  The relative benefits received by the Company on
the one hand and the Purchasers on the other shall be deemed to be in the same
proportion as the total net proceeds from the offering (before deducting
expenses) received by the Company bear to the total discounts and commissions
received by the Purchasers from the Company under this Agreement.  The
relative fault shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or the Purchasers and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission.  The amount paid by an indemnified party as a
result of the losses, claims, damages or liabilities referred to in the first
sentence of this subsection (d) shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any action or claim which is the subject of this
subsection (d).  Notwithstanding the provisions of this subsection (d), no
Purchaser shall be required to contribute any amount in excess of the amount
by which the total price at which the Offered Securities purchased by it were
resold exceeds the amount of any damages which such Purchaser has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission.  The Purchasers' obligations in this subsection
(d) to contribute are several in proportion to their respective purchase
obligations and not joint.

      (e)  The obligations of the Company under this Section shall be in
addition to any liability which the Company may otherwise have and shall
extend, upon the same terms and conditions, to each person, if any, who
controls any Purchaser within the meaning of the Securities Act or the
Exchange Act; and the obligations of the Purchasers under this Section shall
be in addition to any liability which the respective Purchasers may otherwise
have and shall extend, upon the same terms and conditions, to each person, if
any, who controls the Company within the meaning of the Securities Act or the
Exchange Act.

     8.  Default of Purchasers.  If any Purchaser or Purchasers default in
their obligations to purchase Securities hereunder and the aggregate principal
amount of the Offered Securities that such defaulting Purchaser or Purchasers
agreed but failed to purchase does not exceed 10% of the total principal
amount of the Offered Securities, CSFB may make arrangements satisfactory to
the Company for the purchase of such Offered Securities by other persons,
including any of the Purchasers, but if no such arrangements are made by the
Closing Date, the non-defaulting Purchasers shall be obligated severally, in
proportion to their respective commitments hereunder, to purchase the
Securities that such defaulting Purchasers agreed but failed to purchase on
such Closing Date.  If any Purchaser or Purchasers so default and the
aggregate principal amount of the Offered Securities with respect to which
such default or defaults occur exceeds 10% of the total principal amount of
the Offered Securities and arrangements satisfactory to CSFB and the Company
for the purchase of such Offered Securities by other persons are not made
within 36 hours after such default, this Agreement will terminate without
liability on the part of any non-defaulting Purchaser or the Company, except
as provided in Section 9.  As used in this Agreement, the term "Purchaser"
includes any person substituted for a Purchaser under this Section. Nothing
herein will relieve a defaulting Purchaser from liability for its default.

     9.  Survival of Certain Representations and Obligations.  The respective
indemnities, agreements, representations, warranties and other statements of
the Company or its officers and of the several Purchasers set forth in or made
pursuant to this Agreement will remain in full force and effect, regardless of
any investigation, or statement as to the results thereof, made by or on
behalf of any Purchaser, the Company or any of their respective
representatives, officers or directors or any controlling person, and will
survive delivery of and payment for the Offered Securities.  If this Agreement
is terminated pursuant to Section 8 or if for any reason the purchase of the
Offered Securities by the Purchasers is not consummated, the Company shall
remain responsible for the expenses to be paid or reimbursed by it pursuant to
Section 5 and the respective obligations of the Company and the Purchasers
pursuant to Section 7 shall remain in effect.  If  the purchase of the Offered
Securities by the Purchasers is not consummated for any reason other than
solely because of the termination of this Agreement pursuant to Section 8 or
the occurrence of any event specified in clause (iii), (iv), (v), (vi) or
(vii) of Section 6(b), the Company will reimburse the Purchasers for all out-
of-pocket expenses (including fees and disbursements of counsel) reasonably
incurred by them in connection with the offering of the Offered Securities.

     10.  Notices.  All communications hereunder will be in writing and, if
sent to the Purchasers will be mailed, delivered or telegraphed and confirmed
to the Purchasers, c/o Credit Suisse First Boston LLC, One Madison Avenue, New
York, NY 10010-3629, Attention:  Transactions Advisory Group, or, if sent to
the Company, will be mailed, delivered or telegraphed and confirmed to it at
358 South Main Street, Burlington, North Carolina  27215, Attention:  Chief
Legal Officer; provided, however, that any notice to a Purchaser pursuant to
Section 7 will be mailed, delivered or telegraphed and confirmed to such
Purchaser.

     11.  Successors.  This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and the
controlling persons referred to in Section 7, and no other person will have
any right or obligation hereunder, except that holders of Offered Securities
shall be entitled to enforce the agreements for their benefit contained in the
second and third sentences of Section 5(b) hereof against the Company as if
such holders were parties hereto.

     12.  Representation of Purchasers.  CSFB will act for the several
Purchasers in connection with this purchase, and any action under this
Agreement taken by CSFB will be binding upon all the Purchasers.

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

     14.  Applicable Law.  This Agreement shall be governed by, and construed
in accordance with, the laws of the State of New York without regard to
principles of conflicts of laws.

     The Company hereby submits to the non-exclusive jurisdiction of the
Federal and state courts in the Borough of Manhattan in The City of New York
in any suit or proceeding arising out of or relating to this Agreement or the
transactions contemplated hereby.


     If the foregoing is in accordance with the Purchasers' understanding of
our agreement, kindly sign and return to the Company one of the counterparts
hereof, whereupon it will become a binding agreement between the Company and
the several Purchasers in accordance with its terms.

                         Very truly yours,


                                        LABORATORY CORPORATION OF AMERICA

INDENTURE dated as of January 31, 2003, between LABORATORY CORPORATION OF AMERICA HOLDINGS, a Delaware corporation (the "Company"), and WACHOVIA BANK, NATIONAL ASSOCIATION, a national banking association organized under the laws of the United States, as trustee (the "Trustee"). Each party agrees as follows for the benefit of the other parties and for the equal and ratable benefit of the Holders of the Company's 5 1/2% Senior Notes due February 1, 2013.

The Initial Securities and the Trustee's certificate of authentication shall be substantially in the form of Exhibit 1 to the Appendix, the terms and provisions of which are hereby incorporated in and 8

expressly made part of this Indenture. The Exchange Securities, the Private Exchange Securities and the Trustee's certificate of authentication shall be substantially in the form of Exhibit A attached hereto, the terms and provisions of which are hereby incorporated in and expressly made part of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Company is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company). Each Security shall be dated the date of its authentication. The terms of the Securities set forth in the Appendix and Exhibit A are part of the terms of this Indenture. SECTION 2.02. Execution and Authentication. Two Officers shall sign the Securities for the Company by manual or facsimile signature. If an Officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless. A Security shall not be valid until an authorized signatory of the Trustee manually authenticates the Security. The signature of the Trustee on a Security shall be conclusive evidence that such Security has been duly and validly authenticated and issued under this Indenture. The Trustee shall authenticate and make available for delivery the Securities as set forth in the Appendix. The Trustee may appoint an agent (the "Authenticating Agent") reasonably acceptable to the Company to authenticate the Securities. Unless limited by the terms of such appointment, any such Authenticating Agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An Authenticating Agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands. SECTION 2.03. Registrar and Paying Agent. The Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (the "Registrar") and an office or agency where Securities may be presented for payment (the "Paying Agent"). The Registrar shall keep a register of the Securities and of their transfer and 9

exchange. The Company may have one or more co-registrars and one or more additional paying agents. The term "Paying Agent" includes any additional paying agent. The Company shall enter into an appropriate agency agreement with any Registrar, Paying Agent or co-registrar not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee in writing of the name and address of each such agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The Company or any Wholly-Owned Subsidiary incorporated or organized within the United States of America may act as Paying Agent, Registrar, co-registrar or transfer agent. The Company may remove any Registrar or Paying Agent upon written notice to such Registrar or Paying Agent and to the Trustee; provided, however, that no such removal shall become effective until (i) acceptance of an appointment by a successor as evidenced by an appropriate agreement entered into by the Company and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee or (ii) notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above. The Paying Agent or the Registrar may resign as such upon 30 days' prior written notice to the Company and the Trustee; upon resignation of any Paying Agent or Registrar, the Company shall appoint a successor Paying Agent or Registrar, as the case may be, no later than 30 days thereafter and shall provide notice in writing to the Trustee of such successor Paying Agent or Registrar. The Company initially appoints the Trustee as Registrar and Paying Agent for the Securities. SECTION 2.04. Paying Agent To Hold Money in Trust. On the Business Day next preceding the day on which any principal of or interest on any Security is due and payable, the Company shall deposit with the Paying Agent a sum sufficient to pay such principal or interest when due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that such Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by such Paying Agent for the payment of principal of or interest on the Securities and shall notify the Trustee of any default by the Company in making any such payment. If the Company or a Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. 10

The Company at any time may require a Paying Agent (other than the Trustee) to pay all money held by it to the Trustee and to account for any funds disbursed by such Paying Agent. Upon complying with this Section 2.04, the Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money delivered to the Trustee. Upon any bankruptcy, reorganization or similar proceeding with respect to the Company, the Trustee shall serve as Paying Agent for the Securities. SECTION 2.05. Securityholder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Securityholders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee, in writing at least seven Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Securityholders. SECTION 2.06. Transfer and Exchange. The Securities shall be issued in registered form and shall be transferable only upon the surrender of a Security for registration of transfer and in compliance with the Appendix. When a Security is presented to the Registrar or a co-registrar with a request to register a transfer, the Registrar shall register the transfer as requested if the requirements for this Indenture are met. When Securities are presented the Securities shall be issued in registered form and shall be transferable only upon the surrender of a Security for registration to transfer. When Securities are presented to the Registrar or a co-registrar with a request to exchange them for an equal principal amount of Securities of other denominations, the Registrar shall make the exchange as requested if the same requirements are met. SECTION 2.07. Replacement Securities. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security if the Holder provides an affidavit as to such lost, destroyed or stolen Security and provides satisfactory indemnification, including, if required by the Trustee or the Company, indemnity bond sufficient in the judgment of the Company and the Trustee to protect the Company, the Trustee, the Paying Agent, the Registrar and any co- registrar from any loss which any of them may suffer if a Security is replaced. The Company and the Trustee may charge the Holder for their expenses in replacing a Security. 11

Every replacement Security is an additional obligation of the Company under this Indenture. The provisions of this Section 2.07 are exclusive and shall exclude (to the extent lawful) all other rights and remedies with respect to replacement or repayment of mutilated, lost, destroyed or wrongfully taken Securities. SECTION 2.08. Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancelation and those described in this Section 2.08 as not outstanding. Subject to the provisions of Section 10.06, a Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security. If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a protected purchaser (as such term is defined in Section 8-303 of the Uniform Commercial Code). If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or at Stated Maturity money sufficient to pay all principal and interest payable on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case may be, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue. SECTION 2.09. Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities, in the name of the Holder, and deliver them to the Holder in exchange for temporary Securities representing an equal principal amount in authorized denominations. Until so exchanged, the Holder of a temporary Security shall be in all respects entitled to the same benefits as a Holder of definitive Securities. SECTION 2.10. Cancelation. The Company at any time may deliver Securities to the Trustee for cancelation. The Registrar and the Paying Agent shall forward to the Trustee any 12

Securities surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel and destroy in accordance with customary procedures (subject to the record retention requirements of the Exchange Act) all Securities surrendered for registration of transfer, exchange, payment or cancelation and maintain a certificate on file of such destruction unless the Company directs the Trustee in writing to deliver canceled Securities to the Company. The Company may not issue new Securities to replace Securities it has redeemed, paid or delivered to the Trustee for cancelation. The Trustee shall not authenticate Securities in place of canceled Securities other than pursuant to the terms of this Indenture. SECTION 2.11. Defaulted Interest. If the Company defaults in a payment of interest on the Securities, the Company shall pay defaulted interest (plus interest on such defaulted interest to the extent lawful) in any lawful manner. The Company may pay the defaulted interest to the Persons who are Securityholders on a subsequent special record date. The Company shall fix or cause to be fixed (or upon the Company's failure to do so the Trustee shall fix pursuant to a written instruction of Holders of at least a majority in principal amount of the Securities) any such special record date and payment date to the reasonable satisfaction of the Trustee, which specified record date shall not be less than 10 days prior to the payment date for such defaulted interest, and shall promptly mail or cause to be mailed to each Securityholder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid. SECTION 2.12. CUSIP Numbers. The Company in issuing the Securities may use "CUSIP" numbers (if then generally in use) and, if so, the Trustee shall use "CUSIP" numbers in notices as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice and that reliance may be placed only on the other identification numbers printed on the Securities, and no redemption shall be affected by any defect in or omission of such numbers. SECTION 2.13. Issuance of Additional Securities. The Company shall be entitled to issue Additional Securities under this Indenture which shall have identical terms as the Initial Securities issued on the Issue Date, other than with respect to the date of issuance and, if appropriate, the issue price. The Initial Securities issued on the Issue Date, any Additional 13

Securities and all Exchange Securities or Private Exchange Securities issued in exchange therefor shall be treated as a single class for all purposes under this Indenture. With respect to any Additional Securities, the Company shall set forth in a resolution of the Board of Directors and an Officers' Certificate, a copy of each which shall be delivered to the Trustee, the following information: (1) the aggregate principal amount of such Additional Securities to be authenticated and delivered pursuant to this Indenture; (2) the issue price, the issue date and the CUSIP number of such Additional Securities; provided, however, that no Additional Securities may be issued unless such Additional Securities are fungible in all respects for U.S. Federal income tax purposes with the Securities then outstanding as set forth in an Opinion of Counsel addressed to and delivered to the Trustee; (3) whether such Additional Securities shall be Transfer Restricted Securities and issued in the form of Initial Securities as set forth in the Appendix to this Indenture or shall be issued in the form of Exchange Securities as set forth in Exhibit A; and (4) that the Company has complied with this Section 2.13. ARTICLE III Redemption ---------- SECTION 3.01. Notices to Trustee. If the Company elects to redeem Securities pursuant to paragraph 5 of the Securities as set forth in Exhibit 1 to the Appendix, it shall notify the Trustee in writing of the redemption date, the principal amount of Securities to be redeemed and the paragraph of the Securities pursuant to which the redemption will occur. The Company shall give each notice to the Trustee provided for in this Section at least 45 days before the redemption date unless the Trustee consents to a shorter period. Such notice shall be accompanied by an Officers' Certificate and an Opinion of Counsel to the effect that such redemption will comply with the conditions herein. 14

The Trustee shall make the selection from outstanding Securities not previously called for redemption. The Trustee may select for redemption portions of the principal of Securities that have denominations larger than $1,000. Securities and portions of them the Trustee selects to be redeemed shall be in principal amounts of $1,000 or a whole multiple of $1,000. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company promptly of the Securities or portions of Securities to be redeemed. SECTION 3.03. Notice of Redemption.

(b) If the Company shall not act as its own Paying Agent, it shall, by the opening of business (New York City time) on each due date of the principal and interest on any Security, deposit with such Paying Agent a sum in same day funds sufficient to pay the principal of or interest so becoming due, such sum to be held in trust for the benefit of the holders of 18

Securities entitled to such principal of or interest, and (unless such Paying Agent is the Trustee) the Company shall promptly notify the Trustee of its failure so to act. (c) If the Company shall act as its own Paying Agent, it shall, by the opening of business (New York City time) on each due date of the principal and interest on any Security, set aside, segregate and hold in trust for the benefit of the persons entitled thereto, a sum sufficient to pay such principal or interest so becoming due and shall notify the Trustee of any failure to take such action. (d) Anything in this Section 4.04 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust by it, or any Paying Agent hereunder, as required by this Section 4.04, such sums to be held by the Trustee upon the trusts herein contained.

So long as any of the Securities are outstanding, the Company shall not, and shall not permit any Restricted Subsidiary to, create, incur, assume or suffer to exist any Lien upon any Principal Property or shares of stock or Indebtedness of any Restricted Subsidiary to secure any Indebtedness, without effectively providing that the Securities then outstanding shall (so long as such other Indebtedness shall be so secured) be equally and ratably secured; provided, however, that this restriction shall not apply to or prevent the creation or existence of: (a) Liens for taxes not yet due or that are being contested in good faith by appropriate proceedings, provided that adequate reserves with respect thereto are maintained on the books of the Company or its Restricted Subsidiaries, as the case may be, in conformity with GAAP; 19

or development of property or assets used or held by the Company or any Restricted Subsidiary or within one year after such time to secure all or a portion of the purchase price or lease for, or the costs of improvement or development of, such property or assets; (j) any Lien upon any property or assets existing thereon at the time of the acquisition thereof (provided such Lien was not incurred in anticipation of such acquisition) by the Company or any Restricted Subsidiary (whether or not the obligations secured thereby are assumed by the Company or any Restricted Subsidiary); (k) any Lien in favor of the Company or any Restricted Subsidiary; (l) Liens in respect of judgments that do not constitute an Event of Default; (m) Liens to secure any extension, renewal, refinancing or refunding (or successive extensions, renewals, refinancings or refundings), in whole or in part, of any Indebtedness secured by Liens referred to in the foregoing clauses (f) through (l) or Liens created in connection with any amendment, consent or waiver relating to such Indebtedness, so long as such Lien does not extend to any other property and the Indebtedness so secured does not exceed the fair market value (as determined by the Board of Directors) of the assets subject to such Liens at the time of such extension, renewal, refinancing or refunding, or such amendment, consent or waiver, as the case may be; or (n) any Lien securing any Indebtedness in an amount which, together with, without duplication, (1) all other Indebtedness secured by a Lien that is not otherwise permitted by the provisions of this Section 4.06, and (2) all Attributable Debt of the Company and its Subsidiaries with respect to Sale and Leaseback Transactions permitted only under Section 4.07(e), and (3) any indebtedness incurred by a Subsidiary of the Company pursuant to clause (x) or (y) of Section 4.08, does not at the time of the incurrence of the Indebtedness so secured exceed 5% of the Company's Consolidated Total Assets. SECTION 4.07. Limitation on Sale and Leaseback Transactions. So long as any Securities are outstanding, the 21

Company shall not enter into, and shall not permit any Restricted Subsidiary to enter into, any Sale and Leaseback Transaction with respect to any Principal Property unless: (a) such Sale and Leaseback Transaction involves a lease for a term of not more than five years; (b) such Sale and Leaseback Transaction is between the Company and a Subsidiary Guarantor or between Subsidiary Guarantors; (c) the Company or a Restricted Subsidiary would be entitled to incur Indebtedness secured by a Lien on such property or assets involved in such Sale and Leaseback Transaction without equally and ratably securing the Securities pursuant to Section 4.06 above; (d) the cash proceeds of such Sale and Leaseback Transaction are at least equal to the fair market value thereof (as determined in good faith by the Board of Directors) or the debt attributable thereto and the Company applies an amount equal to the greater of the net proceeds of such sale or the Attributable Debt with respect to such Sale and Leaseback Transaction within 270 days of such sale to either (or a combination) of (1) the retirement (other than the mandatory retirement, mandatory prepayment or sinking fund payment or by payment at maturity) of long-term debt of the Company or a Restricted Subsidiary (other than long-term debt that is subordinated to the Securities) or (2) the acquisition, purchase, improvement or development of other comparable property, including the acquisition of other businesses; or (e) any Sale and Leaseback Transaction in an amount which, together with, without duplication, (1) all Attributable Debt of the Company and its Restricted Subsidiaries under this clause (e), (2) all other Indebtedness secured by a Lien that is not otherwise permitted by the provisions of Sections 4.06(a) through (m), and (3) any Indebtedness incurred by a Subsidiary of the Company pursuant to clause (x) or (y) of Section 4.08, does not at the time of such transaction exceed 5% of Consolidated Total Assets.

So long as any Securities are outstanding, the Company shall not cause or permit its direct or indirect Subsidiaries to incur, create, issue, assume or permit to exist any Indebtedness or Preferred Stock (other than Permitted Indebtedness) unless the aggregate principal amount of such 22

Indebtedness or Preferred Stock, when taken together with, without duplication, (1) all other Indebtedness (other than Permitted Indebtedness) incurred pursuant to this Section 4.08, (2) all other Indebtedness secured by a Lien that is not otherwise permitted by the provisions of Section 4.06(a) through (m), and (3) any Sale Leaseback Transactions permitted only under Section 4.07(e), does not at the time of the incurrence exceed the greater of (x) $170 million and (y) 5% of the Company's Consolidated Total Assets.

SECTION 4.09. Compliance Certificate. The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company an Officers' Certificate stating that in the course of the performance by the signers of their duties as Officers of the Company they would normally have knowledge of any Default or Event of Default and whether or not the signers know of any Default or Event of Default that occurred during such period. If they do, the certificate shall describe the Default or Event of Default, its status and what action the Company is taking or proposes to take with respect thereto. The Company also shall comply with TIA Section 314(a)(4). SECTION 4.10. Further Instruments and Acts. Upon request of the Trustee, the Company shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture. SECTION 4.11. SEC Reports.

In addition, at any time that the Company is neither subject to Section 13 or 15(d) of the Exchange Act, nor exempt from reporting pursuant to Rule 12g3- 2(b) under the Exchange Act, the Company shall furnish to the 23

Holders of the Initial Securities and to prospective investors in such Initial Securities, upon the requests of such Holders, any information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act so long as such Securities are not freely transferable under the Securities Act.

The Company shall not consolidate or merge with or into any Person, or sell, lease, convey or otherwise dispose of all or substantially all of its assets, or assign any of its obligations under this Indenture or the Securities, to any Person, unless: (1) the Person formed by or surviving such consolidation or merger (if other than the Company), or to which such sale, lease, conveyance or other disposition or arrangement shall be made (collectively, the "Successor Company"), is a corporation organized and existing under the laws of the United States or any State thereof or the District of Columbia and the Successor Company assumes by supplemental indenture in a form reasonably satisfactory to the Trustee all of the obligations of the Company under this Indenture and under the Securities; (2) immediately after giving effect to such transaction no Default shall have occurred and be continuing; and (3) the Company shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental indenture (if any) comply with this Indenture. The Successor Company shall be the successor to the Company and shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture, and the predecessor Company (except in the case of a lease) shall be released from the obligation to pay the principal of and interest on the Securities. 24

ARTICLE VI Defaults and Remedies --------------------- SECTION 6.01. Events of Default. An "Event of Default" occurs if: (1) the Company defaults in any payment of interest on any Security when the same becomes due and payable and such default continues for a period of 30 days; (2) the Company defaults in the payment of the principal of any Security when the same becomes due and payable at its Stated Maturity, upon optional redemption, upon declaration or otherwise; (3) the Company fails to comply with Section 5.01; (4) the Company fails to comply with any of its agreements in the Securities or this Indenture (other than those referred to in clauses (1), (2) or (3) above) and such failure continues for 60 days after the notice specified below; (5) any default or event of default under any Indebtedness of the Company or any of its Subsidiaries (other than any indebtedness of the Company or any Subsidiary to the seller of a business or asset incurred in connection with the purchase thereof) which default or event of default results in at least $50.0 million of aggregate principal amount of such Indebtedness being declared due and payable prior to maturity (the "cross acceleration provision"); (6) failure by the Company or any of its Subsidiaries to pay at maturity or otherwise when due (after giving effect to any applicable grace period) at least $50.0 million aggregate principal amount of Indebtedness at any one time; (7) the Company pursuant to or within the meaning of any Bankruptcy Law: (A) commences a voluntary case; (B) consents to the entry of an order for relief against it in an involuntary case; 25

(C) consents to the appointment of a Custodian of it or for any substantial part of its property; or (D) makes a general assignment for the benefit of its creditors; or takes any comparable action under any foreign laws relating to insolvency; or (8) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (A) is for relief against the Company in an involuntary case; (B) appoints a Custodian of the Company or for any substantial part of its property; or (C) orders the winding up or liquidation of the Company; or any similar relief is granted under any foreign laws and the order, decree or relief remains unstayed and in effect for 60 days. The foregoing shall constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body. The term "Bankruptcy Law" means Title 11, United States Code, or any similar Federal or state law for the relief of debtors. The term "Custodian" means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law. Notwithstanding the foregoing, a Default under Section 6.01(4) shall not constitute an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the outstanding Securities notify the Company of the Default and the Company does not cure such Default within the time specified in Section 6.01(4) after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a "Notice of Default." 26

The Company shall deliver to the Trustee, within 30 days after the occurrence thereof, written notice in the form of an Officers' Certificate of any Event of Default under clauses (5) and (6) and any event which with the giving of notice or the lapse of time would become an Event of Default under clause (4) or (6), its status and what action the Company is taking or proposes to take with respect thereto. SECTION 6.02. Acceleration. If an Event of Default (other than an Event of Default specified in Section 6.01(7) or (8)) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in outstanding principal amount of the Securities by notice to the Company and the Trustee, may declare the principal of and accrued and unpaid interest on all the Securities to be due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately. If an Event of Default specified in Section 6.01(7) or (8) occurs, the principal of and accrued and unpaid interest on all the Securities shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. The Holders of a majority in principal amount of the Securities outstanding by notice to the Trustee may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of acceleration. No such rescission shall affect any subsequent Default or Event of Default or impair any right consequent thereto. SECTION 6.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture. The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative. SECTION 6.04. Waiver of Past Defaults. The Holders of a majority in outstanding principal amount of the Securities by notice to the Trustee may waive an existing Default and its 27

consequences except (i) a Default in the payment of the principal of or interest on a Security or (ii) a Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Holder affected. When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right. SECTION 6.05. Control by Majority. The Holders of a majority in outstanding principal amount of the Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.01, that the Trustee reasonably determines is unduly prejudicial to the rights of other Holders or would involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. SECTION 6.06. Limitation on Suits. Except to enforce the right to receive payment of principal or interest when due, no Holder may pursue any remedy with respect to this Indenture or the Securities unless: (1) the Holder gives to the Trustee written notice stating that an Event of Default is continuing; (2) the Holders of at least 25% in outstanding principal amount of the Securities make a written request to the Trustee to pursue the remedy; (3) such Holder or Holders offer to the Trustee reasonable security or indemnity against any loss, liability or expense; (4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of security or indemnity; and (5) the Holders of a majority in principal amount of the Securities do not give the Trustee a direction inconsistent with the request during such 60-day period. 28

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder. SECTION 6.07. Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of and interest on the Securities held by such Holder, on or after the respective due dates expressed in the Securities, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. SECTION 6.08. Collection Suit by Trustee. If an Event of Default specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as Trustee of an express trust against the Company for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 7.07. SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company, its Subsidiaries or their respective creditors or properties and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.07. SECTION 6.10. Priorities. If the Trustee collects any money or property pursuant to this Article VI, it shall pay out the money or property in the following order: FIRST: to the Trustee for amounts due under Section 7.07; SECOND: to Holders for amounts due and unpaid on the Securities for principal and interest, ratably, without preference or priority of any kind, according to the 29

amounts due and payable on the Securities for principal and interest, respectively; and THIRD: to the Company. Notwithstanding anything to the contrary in Section 2.11, the Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. At least 15 days before such record date, the Company shall mail to each Holder and the Trustee a notice that states the record date, the payment date and amount to be paid. SECTION 6.11. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in outstanding principal amount of the Securities. SECTION 6.12. Waiver of Stay or Extension Laws. The Company (to the extent it may lawfully do so) shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted. ARTICLE VII Trustee ------- SECTION 7.01. Duties of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise as a 30

prudent person would exercise or use under the circumstances in the conduct of such person's own affairs. (b) Except during the continuance of an Event of Default: (1) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture. (c) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act or its own wilful misconduct, except that: (1) this paragraph does not limit the effect of Section 7.01(b); (2) the Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and (3) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05. (d) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. (e) Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. (f) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties 31

hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. (g) Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 7.01 and to the provisions of the TIA. SECTION 7.02. Rights of Trustee. (a) The Trustee may rely on any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document. (b) Before the Trustee acts or refrains from acting, it may require an Officers' Certificate or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on the Officers' Certificate or Opinion of Counsel. (c) The Trustee may act through its attorneys and agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care. (d) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers; provided, however, that the Trustee's conduct does not constitute wilful misconduct or negligence. (e) The Trustee may consult with counsel, and the advice or opinion of counsel with respect to legal matters relating to this Indenture and the Securities shall be full and complete authorization and protection from liability in respect to any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel. SECTION 7.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11. 32

SECTION 7.04. Trustee's Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company's use of the proceeds from the Securities, it shall not be responsible for the use or application of any money received by any Paying Agent (other than itself as Paying Agent), and it shall not be responsible for any statement of the Company in this Indenture or in any document issued in connection with the sale of the Securities or in the Securities other than the Trustee's certificate of authentication. SECTION 7.05. Notice of Defaults. If a Default or Event of Default occurs and is continuing and it is known to the Trustee, the Trustee shall mail to each Holder notice of the Default or Event of Default within 60 days after it occurs or promptly upon the Trustee's attaining knowledge of such Default or Event of Default, whichever comes first. Except in the case of a Default or Event of Default in payment of principal of, or interest on, any Security, the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is in the interests of Holders. SECTION 7.06. Reports by Trustee to Holders. As promptly as practicable after each May 15 beginning with the May 15 following the date of this Indenture, and in any event prior to July 15 in each year, if required by TIA Section 313, the Trustee shall mail to each Holder a brief report dated as of such May 15 that complies with TIA Section 313(a). The Trustee also shall comply with TIA Section 313(b). The Trustee shall also transmit by mail all reports required by TIA Section 313(c). A copy of each report at the time of its mailing to Holders shall be filed by the Company with the SEC and each stock exchange (if any) on which the Securities are listed. The Company agrees to notify promptly the Trustee whenever the Securities become listed on any stock exchange and of any delisting thereof. SECTION 7.07. Compensation and Indemnity. The Company shall pay to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation for its services. The Trustee's compensation shall not be limited by any law on compensation of a Trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, costs of preparing and reviewing 33

reports, certificates and other documents, costs of preparation and mailing of notices to Holders and reasonable costs of counsel retained by the Trustee in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee's agents, counsel, accountants and experts. The Company shall indemnify and hold harmless the Trustee against any and all loss, liability or expense (including reasonable attorneys' fees) incurred by it in connection with the administration of this trust and the performance of its duties hereunder, including the costs and expenses of enforcing this Indenture (including this Section 7.07) and of defending itself against any claims (whether asserted by any Holder, the Company or otherwise). The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee may have separate counsel and the Company shall pay the fees and expenses of such counsel. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee's own wilful misconduct, negligence or bad faith. To secure the Company's payment obligations in this Section 7.07, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Securities. The Trustee's right to receive payment of any amounts due under this Section 7.07 shall not be subordinate to any other liability or indebtedness of the Company. The Company's payment obligations pursuant to this Section 7.07 shall survive the discharge of this Indenture and the resignation or removal of the Trustee. When the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(7) or (8) with respect to the Company, the expenses are intended to constitute expenses of administration under any Bankruptcy Law. SECTION 7.08. Replacement of Trustee. The Trustee may resign at any time by so notifying the Company. The Holders of a majority in outstanding principal amount of the Securities may remove the Trustee by so notifying the Trustee and may appoint a successor Trustee. The Company shall remove the Trustee if: (1) the Trustee fails to comply with Section 7.10; 34

(2) the Trustee is adjudged bankrupt or insolvent; (3) a receiver or other public officer takes charge of the Trustee or its property; or (4) the Trustee otherwise becomes incapable of acting. If the Trustee resigns, is removed by the Company, is removed by the Holders of a majority in outstanding principal amount of the Securities and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee. A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to the Securityholders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07. If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of 10% in outstanding principal amount of the Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee. If the Trustee fails to comply with Section 7.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. Notwithstanding the replacement of the Trustee pursuant to this Section 7.08, the Company's obligations under Section 7.07 shall continue for the benefit of the retiring Trustee. SECTION 7.09. Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, 35

surviving or transferee corporation or banking association without any further act shall be the successor Trustee. If at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture, any of the Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee, and deliver such Securities so authenticated; and if at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Securities or in this Indenture provided that the certificate of the Trustee shall have. SECTION 7.10. Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of TIA Section 310(a). The Trustee shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. The Trustee shall comply with TIA Section 310(b); provided, however, that there shall be excluded from the operation of TIA Section 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in TIA Section 310(b)(1) are met. SECTION 7.11. Preferential Collection of Claims Against Company. The Trustee shall comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated. ARTICLE VIII Discharge of Indenture; Defeasance ---------------------------------- SECTION 8.01. Discharge of Liability on Securities; Defeasance. (a) When (1) the Company delivers to the Trustee all outstanding Securities (other than Securities replaced pursuant to Section 2.07) for cancelation or (2) all outstanding Securities have become due and payable, whether at Stated Maturity or on a redemption date as a result of the mailing of a notice of redemption pursuant to Article 3 hereof and the 36

Company irrevocably deposits with the Trustee funds sufficient to pay at Stated Maturity or upon redemption all outstanding Securities, including interest thereon to Stated Maturity or such redemption date (other than Securities replaced pursuant to Section 2.07), and if in either case the Company pays all other sums payable hereunder by the Company, then this Indenture shall, subject to Section 8.01(c), cease to be of further effect. The Trustee shall acknowledge satisfaction and discharge of this Indenture on demand of the Company (accompanied by an Officers' Certificate and an Opinion of Counsel stating that all conditions precedent specified herein relating to the satisfaction and discharge of this Indenture have been complied with and at the cost and expense of the Company). (b) Subject to Sections 8.01(c) and 8.02, the Company at any time may terminate (1) all its obligations under the Securities and this Indenture ("legal defeasance option") or (2) its obligations under Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07 and 4.08, and the operation of Sections 6.01(3), 6.01(4), 6.01(5) and 6.01(6) ("covenant defeasance option"); provided, however, no deposit under this Article VIII shall be effective to terminate the obligations of the Company under the Securities or this Indenture prior to 91 days following any such deposit. The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. If the Company exercises its legal defeasance option, payment of the Securities may not be accelerated because of an Event of Default. If the Company exercises its covenant defeasance option, payment of the Securities may not be accelerated because of an Event of Default specified in Sections 6.01(3), 6.01(5) or 6.01(6). Upon satisfaction of the conditions set forth herein and upon request of the Company, the Trustee shall acknowledge in writing the discharge of those obligations that the Company terminates. (c) Notwithstanding the provisions of Sections 7.01(a) and (b), the Company's obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 7.07 and 7.08 and this Article VIII shall survive until the Securities have been paid in full. Thereafter, the Company's obligations in Sections 7.07, 8.04 and 8.05 shall survive. 37

SECTION 8.02. Conditions to Defeasance. The Company may exercise its legal defeasance option or its covenant defeasance option only if: (1) the Company irrevocably deposits in trust with the Trustee money or U.S. Government Obligations for the payment of principal of and interest on the Securities to Stated Maturity or redemption, as the case may be; (2) the Company delivers to the Trustee a certificate from a nationally recognized firm of independent accountants expressing their opinion that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without reinvestment will provide cash at such times and in such amounts as will be sufficient to pay principal and interest when due on all the Securities to Stated Maturity or redemption, as the case may be; (3) 91 days pass after the deposit is made and during the 91-day period no Default specified in Sections 6.01(7) or (8) occurs which is continuing at the end of the periods; (4) the deposit does not constitute a default under any other agreement binding on the Company; (5) the Company delivers to the Trustee an Opinion of Counsel to the effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940; (6) in the case of the legal defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (B) since the date of this Indenture there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Securityholders will not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such legal defeasance had not occurred; 38

(7) in the case of the covenant defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Securityholders shall not recognize income, gain or loss for Federal income tax purposes as a result of such covenant defeasance and shall be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred; (8) the Securityholders shall have a perfected security interest under applicable law in the cash or U.S. Government Obligations deposited pursuant to Section 8.02(1) above; (9) the Company shall have delivered to the Trustee an Opinion of Counsel, in form and substance reasonably satisfactory to the Trustee, to the effect that, after the passage of 91 days following the deposit, the trust funds shall not be subject to any applicable bankruptcy, insolvency, reorganization or similar law affecting creditors' rights generally; (10) such defeasance shall not cause the Trustee to have a conflicting interest with respect to any securities of the Company; and (11) the Company delivers to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Securities and this Indenture as contemplated by this Article VIII have been complied with. Before or after a deposit, the Company may make arrangements satisfactory to the Trustee for the redemption of Securities at a future date in accordance with Article III. SECTION 8.03. Application of Trust Money. The Trustee shall hold in trust money or U.S. Government Obligations deposited with it pursuant to this Article VIII. It shall apply the deposited money and the money from U.S. Government Obligations through the Paying Agent and in accordance with this Indenture to the payment of principal of and interest on the Securities. SECTION 8.04. Repayment to Company. The Trustee and the Paying Agent shall promptly turn over to the Company upon request any excess money or securities held by them upon payment of all the obligations under this Indenture. 39

Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Company upon request any money held by them for the payment of principal of or interest on the Securities that remains unclaimed for two years, and, thereafter, Securityholders entitled to the money must look to the Company for payment as general creditors. SECTION 8.05. Indemnity for U.S. Government Obligations. The Company shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations. SECTION 8.06. Reinstatement. If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article VIII by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the obligations of the Company under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to this Article VIII until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article VIII; provided, however, that, if the Company has made any payment of interest on or principal of any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent. ARTICLE IX Amendments ---------- SECTION 9.01. Without Consent of Holders. The Company and the Trustee may amend this Indenture or the Securities without notice to or consent of any Holder: (1) to cure any ambiguity, omission, defect or inconsistency; (2) to comply with Article V; (3) to provide for uncertificated Securities in addition to or in place of certificated Securities; 40

provided, however, that the uncertificated Securities are issued in registered form for purposes of Section 163(f) of the Code or in a manner such that the uncertificated Securities are described in Section 163(f)(2)(B) of the Code; (4) to add guarantees with respect to the Securities, or to secure the Securities. (5) to add to the covenants of the Company for the benefit of the Holders or to surrender any right or power herein conferred upon the Company; (6) to make any change that does not adversely affect the rights of any Holder; or (7) to comply with any requirement of the SEC in connection with qualifying this Indenture under the TIA. After an amendment under this Section 9.01 becomes effective, the Company shall mail to each Securityholder a notice briefly describing such amendment. The failure to give such notice to all Securityholders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.01. SECTION 9.02. With Consent of Holders. The Company and the Trustee may amend this Indenture or the Securities without notice to any Securityholder but with the written consent of the Holders of at least a majority in principal amount of the Securities then outstanding (including consents obtained in connection with a tender offer or exchange for the Securities). However, without the consent of each Securityholder affected thereby, an amendment may not: (1) reduce the amount of Securities whose Holders must consent to an amendment; (2) reduce the rate of or extend the time for payment of interest on any Security; (3) reduce the principal of, or extend the Stated Maturity of, any Security; (4) make any Security payable in money other than that stated in such Security; 41

(5) reduce the amount payable upon redemption of any Security or change the time at which any Security may be redeemed in accordance with Article III; (6) modify or affect in any manner adverse to the Holders the right of any Holder of the Securities to receive payment of principal of and interest on such Holder's Securities on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder's Securities; (7) make any change in Section 6.04 or 6.07 or the second sentence of this Section 9.02; or (8) make any change in the ranking or priority of any Security that would adversely affect the holders of the Securities. It shall not be necessary for the consent of the Holders under this Section to approve the particular form of any proposed amendment, but it shall be sufficient if such consent approves the substance thereof. After an amendment under this Section 8.02 becomes effective, the Company shall mail to Securityholders a notice briefly describing such amendment. The failure to give such notice to all Securityholders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.02. SECTION 9.03. Compliance with Trust Indenture Act. Every amendment to this Indenture or the Securities shall comply with the TIA as then in effect. SECTION 9.04. Revocation and Effect of Consents and Waivers. A consent to an amendment or a waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same debt as the consenting Holder's Security, even if notation of the consent or waiver is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder's Security or portion of the Security if the Trustee receives the notice of revocation before the date the amendment or waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every Holder. An amendment or waiver becomes effective upon the execution of such amendment or waiver by the Trustee and the Company. 42

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. SECTION 9.05. Notation on or Exchange of Securities. If an amendment changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may, but shall not be required to, place an appropriate notation on the Security regarding the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. Failure to make the appropriate notation or to issue a new Security shall not affect the validity of such amendment. SECTION 9.06. Trustee To Sign Amendments. The Trustee shall sign any amendment authorized pursuant to this Article IX if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such amendment the Trustee shall be entitled to receive indemnity reasonably satisfactory to it and to receive, and (subject to Section 7.01) shall be fully protected in relying upon, an Officers' Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture. SECTION 9.07. Payment for Consent. Neither the Company nor any Affiliate of the Company shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Securities unless such consideration is offered to be paid to all Holders that so consent, waive or agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or agreement. 43

Also, subject to the foregoing, only Securities outstanding at the time shall be considered in any such determination. SECTION 10.07. Rules by Trustee, Paying Agent and Registrar. The Trustee may make reasonable rules for action by or a meeting of Holders. The Registrar and the Paying Agent may make reasonable rules for their functions. SECTION 10.08. Legal Holidays.

ANNEX A [FORM OF SUPPLEMENTAL INDENTURE TO BE DELIVERED BY SUBSIDIARY GUARANTORS] SUPPLEMENTAL INDENTURE (this "Supplemental Indenture"), dated as of [ ] among [ ] (the "Subsidiary Guarantor"), a [ ] corporation and a subsidiary of Laboratory Corporation of America Holdings, a Delaware corporation (or its permitted successor) (the "Company"), the Company, [other Subsidiary Guarantors] and Wachovia Bank, National Association, as Trustee under the Indenture (the "Trustee"). W I T N E S S E T H WHEREAS, the Company has heretofore executed and delivered to the Trustee an indenture (the "Indenture"), dated as of January 31, 2003, providing for the issuance of an aggregate principal amount of $350,000,000 of 5 1/2% Senior Notes due February 1, 2013 (the "Securities"); WHEREAS, in its discretion, the Company may have the Subsidiary Guarantor to execute and deliver to the Trustee a Guaranty Agreement pursuant to which the Subsidiary Guarantor will Guarantee payment of the Securities; and WHEREAS, pursuant to Section 9.01(4) of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture. NOW THEREFORE, in consideration of the foregoing and for good and valuable consideration, the receipt of which is hereby acknowledged, the Company, the Subsidiary Guarantor[, the other Subsidiary Guarantors] and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Securities as follows: SECTION 1. Capitalized Terms. Capitalized terms used herein but not defined shall have the meanings assigned to them in the Indenture. SECTION 2. Guaranties. The Subsidiary Guarantor hereby unconditionally and irrevocably guarantees[, jointly and severally with the other Guarantors], to each Holder and to the Trustee and its successors and assigns (a) the full and punctual payment of principal of and interest on the Securities when due,

whether at maturity, by acceleration, by redemption or otherwise, and all other monetary obligations of the Company under the Indenture and the Securities and (b) the full and punctual performance within applicable grace periods of all other obligations of the Company under the Indenture and the Securities (all the foregoing being hereinafter collectively called the "Obligations"). The Subsidiary Guarantor further agrees that the Obligations may be extended or renewed, in whole or in part, without notice to or further assent from the Subsidiary Guarantor and that the Subsidiary Guarantor will remain bound under this Supplemental Indenture notwithstanding any extension or renewal of any Obligation. The Subsidiary Guarantor waives presentation to, demand of, payment from and protest to the Company of any of the Obligations and also waives notice of protest for nonpayment. The Subsidiary Guarantor waives notice of any default under the Securities or the Obligations. The obligations of the Subsidiary Guarantor hereunder shall not be affected by (a) the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person under the Indenture, this Supplemental Indenture, the Securities or any other agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of the Indenture, this Supplemental Indenture, the Securities or any other agreement; (d) the release of any security held by any Holder or the Trustee for the Obligations or any of them; (e) the failure of any Holder or the Trustee to exercise any right or remedy against any other guarantor of the Obligations; or (f) except as set forth in Section 7 of this Supplemental Indenture, any change in the ownership of the Subsidiary Guarantor. The Subsidiary Guarantor further agrees that its guaranty herein constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder or the Trustee to any security held for payment of the Obligations. Except as expressly set forth in Section 8.01(b) of the Indenture and Sections 3 and 7 of this Supplemental Indenture, the obligations of the Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, 2

release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of the Subsidiary Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under the Indenture, this Supplemental Indenture, the Securities or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, wilful or otherwise, in the performance of the Obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of the Subsidiary Guarantor or would otherwise operate as a discharge of the Subsidiary Guarantor as a matter of law or equity. The Subsidiary Guarantor further agrees that its guaranty herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise. In furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee has at law or in equity against the Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay the principal of or interest on any Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Obligation, the Subsidiary Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of (1) the unpaid amount of such Obligations, (2) accrued and unpaid interest on such Obligations (but only to the extent not prohibited by law) and (3) all other monetary Obligations of the Company to the Holders and the Trustee. The Subsidiary Guarantor agrees that, as between it, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article 6 of the Indenture for the purposes of the Subsidiary Guarantor's guaranty herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations 3

guaranteed hereby, and (y) in the event of any declaration of acceleration of such Obligations as provided in Article 6 of the Indenture, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Subsidiary Guarantor for the purposes of this Supplemental Indenture. The Subsidiary Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys' fees) incurred by the Trustee or any Holder in enforcing any rights under this Section 2. SECTION 3. Limitation on Liability. Any term or provision of this Supplemental Indenture to the contrary notwithstanding, the maximum aggregate amount of the Obligations guaranteed hereunder by the Subsidiary Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Supplemental Indenture, as it relates to the Subsidiary Guarantor, voidable under applicable law relating to fraudulent conveyance, fraudulent transfer or similar laws affecting the rights of creditors generally. SECTION 4. Successors and Assigns. This Supplemental Indenture shall be binding upon the Subsidiary Guarantor and its successors and assigns and shall inure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that party in this Supplemental Indenture and in the Securities shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Supplemental Indenture. SECTION 5. No Waiver. Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Supplemental Indenture shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Supplemental Indenture at law, in equity, by statute or otherwise. SECTION 6. Modification. No modification, amendment or waiver of any provision of this Supplemental Indenture, nor the consent to any departure by the Subsidiary Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or 4

consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on the Subsidiary Guarantor in any case shall entitle the Subsidiary Guarantor to any other or further notice or demand in the same, similar or other circumstances. SECTION 7. Release. Upon the sale or other disposition (including by way of consolidation or merger) of the Subsidiary Guarantor or the sale or disposition of all or substantially all the assets of the Subsidiary Guarantor (in each case other than a sale or disposition to the Company or an affiliate of the Company), the Subsidiary Guarantor shall be deemed released from all obligations under this Supplemental Indenture without any further action required on the part of the Trustee or any Holder. At the request and expense of the Company, the Trustee shall execute and deliver an appropriate instrument evidencing such release. Upon the merger or consolidation of the Subsidiary Guarantor with or into, or the dissolution and liquidation of the Subsidiary Guarantor into, a Subsidiary Guarantor or another Person that Guarantees the Securities, the Subsidiary Guarantor shall be released from all obligations under this Supplemental Indenture without any further action required on the part of the Trustee or any Holder. At the request and expense of the Company, the Trustee shall execute and deliver an appropriate instrument evidencing such release. SECTION 8. Governing Law. This Supplemental Indenture shall be governed by, and construed in accordance with, the laws of the State of New York but without giving effect to applicable principles of conflicts of law to the extent that the application of the laws of another jurisdiction would be required thereby. SECTION 9. No Recourse Against Others. A director, officer, employee or stockholder, as such, of the Subsidiary Guarantor shall not have any liability for any obligations of the Company under the Securities or the Indenture or of the Subsidiary Guarantor under its guaranty, the Indenture or this Supplemental Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Holder shall waive and release all such liability. The waiver and release shall be part of the consideration for the issue of the Securities. SECTION 10. Multiple Originals. The parties may sign any number of copies of this Supplemental Indenture. Each signed 5

copy shall be an original, but all of them together represent the same agreement. One signed copy is enough to prove this Supplemental Indenture. SECTION 11. Headings. The headings of the Sections of this Supplemental Indenture have been inserted for convenience of reference only, are not intended to be considered a part hereof and shall not modify or restrict any of the terms or provisions hereof.

15 [FORM OF REVERSE SIDE OF INITIAL SECURITY] 5 1/2% Senior Note due February 1, 2013 1. Interest Laboratory Corporation of America Holdings, a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the "Company"), promises to pay interest on the principal amount of this Security at the rate per annum shown above; provided, however, that if a Registration Default (as defined in the Registration Rights Agreement) occurs, additional interest will accrue on this Security at a rate of 0.50% per annum (increasing by an additional 0.50% per annum after each consecutive 90-day period that occurs after the date on which such Registration Default occurs up to a maximum additional interest rate of 2.00%) from and including the date on which any such Registration Default shall occur to but excluding the date on which all Registration Defaults have been cured. The Company will pay interest semiannually on February 1 and August 1 of each year, commencing August 1, 2003. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from January 31, 2003. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The Company will pay interest on overdue principal at the rate borne by the Securities plus 1% per annum, and it will pay interest on overdue installments of interest at the same rate to the extent lawful. 2. Method of Payment The Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered holders of Securities at the close of business on the January 15 or July 15 next preceding the interest payment date even if Securities are canceled after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository

16 Trust Company. The Company will make all payments in respect of a certificated Security (including principal, premium and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on a certificated Security will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately pre- ceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion). 3. Paying Agent and Registrar Initially, Wachovia Bank, National Association, a national banking association (the "Trustee"), will act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent, Registrar or co-registrar without notice. The Company or any of its domestically incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or co-registrar. 4. Indenture The Company issued the Securities under an Indenture dated as of January 31, 2003 ("Indenture"), between the Company and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C.

The Securities are subject to all such terms, and Securityholders are referred to the Indenture and the Act for a statement of those terms. The Securities are general unsecured obligations of the Company. The Company shall be entitled to issue Additional Securities pursuant to Section 2.13 of the Indenture. The Initial Securities issued on the Issue Date, any Additional Securities and all Exchange Securities or Private Exchange Securities issued in exchange therefor will be treated as a single class for all purposes under the Indenture. The Indenture contains covenants that limit the ability of the Company and its Restricted Subsidiaries to create liens on assets and engage in Sale and Leaseback Transactions. The Indenture also contains a covenant that limits the ability of the Company's Subsidiaries from incurring indebtedness or

17 issuing preferred stock. These covenants are subject to important exceptions and qualifications. 5. Optional Redemption The Securities are subject to redemption, in whole or in part, at the option of the Company, at any time at a redemption price equal to the greater of (1) 100% of the principal amount of the Securities being redeemed plus accrued and unpaid interest to the redemption date or (2) the Make-Whole Amount for the Securities being redeemed. "Make Whole Amount" means the sum, as determined by a Quotation Agent, of the present values of the principal amount of the Securities to be redeemed, together with scheduled payments of interest (exclusive of interest to the redemption date) from the redemption date to the maturity date of the Securities being redeemed, in each case discounted to the redemption date on a semi-annual basis, assuming a 360-day year consisting of twelve 30-day months, at the Adjusted Treasury Rate, plus accrued and unpaid interest on the principal amount of the Securities being redeemed to the redemption date. "Adjusted Treasury Rate" means, with respect to any redemption date, (i) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated "H.15(519)" or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption "Treasury Constant Maturities," for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the remaining term of the Securities of the series being redeemed, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month) or (ii) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semi- annual equivalent yield to maturity of the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date, in each case calculated on the third Business Day preceding the redemption date, plus 0.25%.

18 "Comparable Treasury Issue" means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term from the redemption date to the maturity date of the Securities being redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Securities. "Comparable Treasury Price" means, with respect to any redemption date, if clause (ii) of the Adjusted Treasury Rate is applicable, the average of three, or such lesser number as is obtained by the Trustee, Reference Treasury Dealer Quotations for such redemption date. "Quotation Agent" means the Reference Treasury Dealer selected by the Company. "Reference Treasury Dealer" means Credit Suisse First Boston Corporation and its successors and assigns, and two other nationally recognized investment banking firms selected by the Company that are primary U.S. Government securities dealers. "Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such redemption date. 6. Notice of Redemption Notice of redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each Holder of Securities to be redeemed at his registered address. Securities in denominations larger than $1,000 principal amount may be redeemed in part but only in whole multiples of $1,000. If money sufficient to pay the redemption price of and accrued interest on all Securities (or portions thereof) to be redeemed on the redemption date is deposited with the Paying Agent on or before the redemption date and certain other conditions are satisfied, on and after such date interest ceases to accrue on such Securities (or such portions thereof) called for redemption.

19 7. Denominations; Transfer; Exchange The Securities are in registered form without coupons in denominations of $1,000 principal amount and whole multiples of $1,000. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or any Securities for a period of 15 days before a selection of Securities to be redeemed or 15 days before an interest payment date. 8. Persons Deemed Owners The registered Holder of this Security may be treated as the owner of it for all purposes. 9. Unclaimed Money If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for payment. 10. Discharge and Defeasance Subject to certain conditions, the Company at any time shall be entitled to terminate some or all of its obligations under the Securities and the Indenture if the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Securities to redemption or maturity, as the case may be. 11. Amendment, Waiver Subject to certain exceptions set forth in the Indenture, (i) the Indenture and the Securities may be amended with the written consent of the Holders of at least a majority in principal amount outstanding of the Securities and (ii) any default or noncompliance with any provision may be waived with the written consent of the Holders of a majority in principal

20 amount outstanding of the Securities. Subject to certain exceptions set forth in the Indenture, without the consent of any Securityholder, the Company and the Trustee shall be entitled to amend the Indenture or the Securities to cure any ambiguity, omission, defect or inconsistency, or to comply with Article 5 of the Indenture, or to provide for uncertificated Securities in addition to or in place of certificated Securities, or to add guarantees with respect to the Securities or to secure the Securities, or to add additional covenants or surrender rights and powers conferred on the Company or to comply with any request of the SEC in connection with qualifying the Indenture under the Act or to make any change that does not adversely affect the rights of any Securityholder. 12. Defaults and Remedies Under the Indenture, Events of Default include (i) default for 30 days in payment of interest on the Securities; (ii) default in payment of principal on the Securities, upon redemption pursuant to paragraph 5 of the Securities, upon acceleration or otherwise; (iii) failure by the Company to comply with other agreements in the Indenture or the Securities, in certain cases subject to notice and lapse of time; (iv) certain accelerations of other Indebtedness of the Company if the amount accelerated (or so unpaid) exceeds $50.0 million; (v) failure by the Company or any Subsidiary to pay at maturity at least $50.0 million of other Indebtedness; and (vi) certain events of bankruptcy or insolvency with respect to the Company and its Subsidiaries. Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default (except a Default in payment of principal or interest) if it determines that withholding notice is in the interest of the Holders. 13. Trustee Dealings with the Company Subject to certain limitations imposed by the Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the

21 Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 14. No Recourse Against Others A director, officer, employee or stockholder, as such, of the Company or the Trustee shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Securityholder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities. 15. Authentication This Security shall not be valid until an authorized signatory of the Trustee (or an Authenticating Agent) manually signs the certificate of authentication on the other side of this Security. 16. Abbreviations Customary abbreviations may be used in the name of a Securityholder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gifts to Minors Act). 17. CUSIP Numbers Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Securityholders. No representation is made as to the accuracy of such numbers either as printed on the Securities or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon. 18. Holders' Compliance with Registration Rights Agreement Each Holder of a Security, by acceptance hereof, acknowledges and agrees to the provisions of the Registration

22 Rights Agreement, including the obligations of the Holders with respect to a registration and the indemnification of the Company to the extent provided therein. 19. Governing Law THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

Interest Laboratory Corporation of America Holdings, a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the "Company"), promises to pay interest on the principal amount of this Security at the rate per annum shown above; [provided, however, that if a Registration Default (as defined in the Registration Rights Agreement) occurs, additional interest will accrue on this Security at a rate of 0.50% per annum (increasing by an additional 0.50% per annum after each consecutive 90-day period that occurs after the date on which such Registration Default occurs up to a maximum additional interest rate of 2.00%) from and including the date on which any such Registration Default shall occur to but excluding the date on which all Registration Defaults have been cured.](1) The Company will pay interest semiannually on February 1 and August 1 of each year, commencing August 1, 2003. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from January 31, 2003. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The Company will pay interest on overdue principal at the rate borne by the Securities plus 1% per annum, and it will pay interest on overdue installments of interest at the same rate to the extent lawful. 2. Method of Payment The Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered holders of Securities at the close of business on the January 15 or July 15 next preceding the interest payment date even if Securities are canceled after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and _______________________ (1) Insert if at the date of issuance of the Exchange Security or Private Exchange Security, as the case may be, any Registration Default has occurred with respect to the related Initial Securities during the interest period in which such date of issuance occurs.

4 private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Company will make all payments in respect of a certificated Security (including principal, premium and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on a certificated Security will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately pre- ceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion). 3. Paying Agent and Registrar Initially, Wachovia Bank, National Association, a national banking association (the "Trustee"), will act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent, Registrar or co-registrar without notice. The Company or any of its domestically incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or co-registrar. 4. Indenture The Company issued the Securities under an Indenture dated as of January 31, 2003 ("Indenture"), between the Company and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. '' 77aaa-77bbbb) as in effect on the date of the Indenture (the "Act"). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture and the Act for a statement of those terms. The Securities are general unsecured obligations of the Company. The Company shall be entitled to issue Additional Securities pursuant to Section 2.13 of the Indenture. The Initial Securities issued on the Issue Date, any Additional Securities and all Exchange Securities or Private Exchange Securities issued in exchange therefor will be treated as a single class for all purposes under the Indenture. The Indenture contains covenants that limit the ability of the Company and its Restricted Subsidiaries to create liens on assets and engage in Sale and Leaseback Transactions. The

5 Indenture also contains a covenant that limits the ability of the Company's Subsidiaries from incurring indebtedness or issuing preferred stock. These covenants are subject to important exceptions and qualifications. 5. Optional Redemption The Securities are subject to redemption, in whole or in part, at the option of the Company, at any time at a redemption price equal to the greater of (1) 100% of the principal amount of the Securities being redeemed plus accrued and unpaid interest to the redemption date or (2) the Make-Whole Amount for the Securities being redeemed. "Make Whole Amount" means the sum, as determined by a Quotation Agent, of the present values of the principal amount of the Securities to be redeemed, together with scheduled payments of interest (exclusive of interest to the redemption date) from the redemption date to the maturity date of the Securities being redeemed, in each case discounted to the redemption date on a semi-annual basis, assuming a 360-day year consisting of twelve 30-day months, at the Adjusted Treasury Rate, plus accrued and unpaid interest on the principal amount of the Securities being redeemed to the redemption date. "Adjusted Treasury Rate" means, with respect to any redemption date, (i) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated "H.15(519)" or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption "Treasury Constant Maturities," for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the remaining term of the Securities of the series being redeemed, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month) or (ii) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semi- annual equivalent yield to maturity of the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date, in

6 each case calculated on the third Business Day preceding the redemption date, plus 0.25%. "Comparable Treasury Issue" means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term from the redemption date to the maturity date of the Securities being redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Securities. "Comparable Treasury Price" means, with respect to any redemption date, if clause (ii) of the Adjusted Treasury Rate is applicable, the average of three, or such lesser number as is obtained by the Trustee, Reference Treasury Dealer Quotations for such redemption date. "Quotation Agent" means the Reference Treasury Dealer selected by the Company. "Reference Treasury Dealer" means Credit Suisse First Boston Corporation and its successors and assigns, and two other nationally recognized investment banking firms selected by the Company that are primary U.S. Government securities dealers. "Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such redemption date. 6. Notice of Redemption Notice of redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each Holder of Securities to be redeemed at his registered address. Securities in denominations larger than $1,000 principal amount may be redeemed in part but only in whole multiples of $1,000. If money sufficient to pay the redemption price of and accrued interest on all Securities (or portions thereof) to be redeemed on the redemption date is deposited with the Paying Agent on or before the redemption date and certain other conditions are satisfied, on and after such date interest ceases to accrue on

7 such Securities (or such portions thereof) called for redemption. 7. Denominations; Transfer; Exchange The Securities are in registered form without coupons in denominations of $1,000 principal amount and whole multiples of $1,000. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or any Securities for a period of 15 days before a selection of Securities to be redeemed or 15 days before an interest payment date. 8. Persons Deemed Owners The registered Holder of this Security may be treated as the owner of it for all purposes. 9. Unclaimed Money If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for payment. 10. Discharge and Defeasance Subject to certain conditions, the Company at any time shall be entitled to terminate some or all of its obligations under the Securities and the Indenture if the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Securities to redemption or maturity, as the case may be. 11. Amendment, Waiver Subject to certain exceptions set forth in the Indenture, (i) the Indenture and the Securities may be amended with the written consent of the Holders of at least a majority in principal amount outstanding of the Securities and (ii) any

8 default or noncompliance with any provision may be waived with the written consent of the Holders of a majority in principal amount outstanding of the Securities. Subject to certain exceptions set forth in the Indenture, without the consent of any Securityholder, the Company and the Trustee shall be entitled to amend the Indenture or the Securities to cure any ambiguity, omission, defect or inconsistency, or to comply with Article 5 of the Indenture, or to provide for uncertificated Securities in addition to or in place of certificated Securities, or to add guarantees with respect to the Securities or to secure the Securities, or to add additional covenants or surrender rights and powers conferred on the Company or to comply with any request of the SEC in connection with qualifying the Indenture under the Act or to make any change that does not adversely affect the rights of any Securityholder. 12. Defaults and Remedies Under the Indenture, Events of Default include (i) default for 30 days in payment of interest on the Securities; (ii) default in payment of principal on the Securities, upon redemption pursuant to paragraph 5 of the Securities, upon acceleration or otherwise; (iii) failure by the Company to comply with other agreements in the Indenture or the Securities, in certain cases subject to notice and lapse of time; (iv) certain accelerations of other Indebtedness of the Company if the amount accelerated (or so unpaid) is at least $50.0 million; (v) failure by the Company or any Subsidiary to pay at maturity at least $50.0 million of other Indebtedness; and (vi) certain events of bankruptcy or insolvency with respect to the Company and its Subsidiaries. Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default (except a Default in payment of principal or interest) if it determines that withholding notice is in the interest of the Holders. 13. Trustee Dealings with the Company Subject to certain limitations imposed by the Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may

9 otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 14. No Recourse Against Others A director, officer, employee or stockholder, as such, of the Company or the Trustee shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Securityholder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities. 15. Authentication This Security shall not be valid until an authorized signatory of the Trustee (or an Authenticating Agent) manually signs the certificate of authentication on the other side of this Security. 16. Abbreviations Customary abbreviations may be used in the name of a Securityholder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gifts to Minors Act). 17. CUSIP Numbers Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Securityholders. No representation is made as to the accuracy of such numbers either as printed on the Securities or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

Dear Sirs:

     Laboratory Corporation of America Holdings, a Delaware corporation (the
"Company"), proposes to issue and sell to Credit Suisse First Boston LLC and
Banc of America Securities LLC, UBS Warburg LLC, Wachovia Securities, Inc.,
SunTrust Capital Markets, Inc. and U.S. Bancorp Piper Jaffray Inc.
(collectively, the "Initial Purchasers"), upon the terms set forth in a
purchase agreement of even date herewith (the "Purchase Agreement"),
$350,000,000 aggregate principal amount of its 5 1/2% Senior Notes due
February 1, 2013 (the "Initial Securities").  The Initial Securities will be
issued pursuant to an Indenture, dated as of January 31, 2003 (the
"Indenture"), among the Company and Wachovia Bank, National Association, as
trustee  (the "Trustee").  As an inducement to the Initial Purchasers to
enter into the Purchase Agreement, the Company agrees with the Initial
Purchasers, for the benefit of the Initial Purchasers and the holders of the
Securities (as defined below) (collectively the "Holders"), as follows:

     1.  Registered Exchange Offer.  Unless not permitted by applicable law,
the Company shall prepare and, not later than 90 days (such 90th day being a
"Filing Deadline") after the date on which the Initial Purchasers purchase
the Initial Securities pursuant to the Purchase Agreement (the "Closing
Date"), file with the Securities and Exchange Commission (the "Commission") a
registration statement (the "Exchange Offer Registration Statement") on an
appropriate form under the Securities Act of 1933, as amended (the
"Securities Act"), with respect to a proposed offer (the "Registered Exchange
Offer") to the Holders of Transfer Restricted Securities (as defined in
Section 6 hereof), who are not prohibited by any law or policy of the
Commission from participating in the Registered Exchange Offer, to issue and
deliver to such Holders, in exchange for the Initial Securities, a like
aggregate principal amount of debt securities of the Company issued under the
Indenture, identical in all material respects to the Initial Securities and
registered under the Securities Act (the "Exchange Securities").  The Company
shall use its reasonable best efforts to (i) cause such Exchange Offer
Registration Statement to become effective under the Securities Act within
180 days after the Closing Date (such 180th day being an "Effectiveness
Deadline")  and (ii)  keep the Exchange Offer Registration Statement
effective for not less than 30 days (or longer, if required by applicable
law) after the date notice of the Registered Exchange Offer is mailed to the
Holders (such period being called the "Exchange Offer Registration Period").

     If the Company commences the Registered Exchange Offer, the Company (i)
will be entitled to consummate the Registered Exchange Offer 30 days after
such commencement (provided that the Company has accepted all the Initial
Securities theretofore validly tendered in accordance with the terms of the
Registered Exchange Offer) and (ii) will be required to consummate the
Registered Exchange Offer no later than 40 days after the date on which the
Exchange Offer Registration Statement is declared effective (such 40th day
being the "Consummation Deadline").

     Following the declaration of the effectiveness of the Exchange Offer
Registration Statement, the Company shall promptly commence the Registered
Exchange Offer, it being the objective of such Registered Exchange Offer to
enable each Holder of Transfer Restricted Securities electing to exchange the
Initial Securities for Exchange Securities (assuming that such Holder is not
an affiliate of the Company within the meaning of the Securities Act,
acquires the Exchange Securities in the ordinary course of such Holder's
business and has no arrangements with any person to participate in the
distribution of the Exchange Securities and is not prohibited by any law or
policy of the Commission from participating in the Registered Exchange Offer)
to trade such Exchange Securities from and after their receipt without any
limitations or restrictions under the Securities Act and without material
restrictions under the securities laws of the several states of the United
States.

     The Company and the Initial Purchasers acknowledge that, pursuant to
current interpretations by the Commission's staff of Section 5 of the
Securities Act, in the absence of an applicable exemption therefrom, (i) each
Holder that is a broker-dealer electing to exchange Initial Securities,
acquired for its own account as a result of market making activities or other
trading activities, for Exchange Securities (an "Exchanging Dealer"), is
required to deliver a prospectus containing the information set forth in (a)
Annex A hereto on the cover, (b) Annex B hereto in the "Exchange Offer
Procedures" section and the "Purpose of the Exchange Offer" section, and (c)
Annex C hereto in the "Plan of Distribution" section of such prospectus in
connection with a sale of any such Exchange Securities received by such
Exchanging Dealer pursuant to the Registered Exchange Offer and (ii) an
Initial Purchaser that elects to sell Securities (as defined below) acquired
in exchange for Initial Securities constituting any portion of an unsold
allotment, is required to deliver a prospectus containing the information
required by Items 507 or 508 of Regulation S-K under the Securities Act, as
applicable, in connection with such sale.

     The Company shall use its best efforts to keep the Exchange Offer
Registration Statement effective and to amend and supplement the prospectus
contained therein, in order to permit such prospectus to be lawfully
delivered by all persons subject to the prospectus delivery requirements of
the Securities Act for such period of time as such persons must comply with
such requirements in order to resell the Exchange Securities; provided,
however, that (i) in the case where such prospectus and any amendment or
supplement thereto must be delivered by an Exchanging Dealer or an Initial
Purchaser, such period shall be the lesser of 180 days and the date on which
all Exchanging Dealers and the Initial Purchasers have sold all Exchange
Securities held by them (unless such period is extended pursuant to Section
3(j) below) and (ii) the Company shall make such prospectus and any amendment
or supplement thereto available to any broker-dealer for use in connection
with any resale of any Exchange Securities for a period of not less than 180
days after the consummation of the Registered Exchange Offer.

     If, upon consummation of the Registered Exchange Offer, any Initial
Purchaser holds Initial Securities acquired by it as part of its initial
distribution, the Company, simultaneously with the delivery of the Exchange
Securities pursuant to the Registered Exchange Offer, shall issue and deliver
to such Initial Purchaser upon the written request of such Initial Purchaser,
in exchange (the "Private Exchange") for the Initial Securities held by such
Initial Purchaser, a like principal amount of debt securities of the Company
issued under the Indenture and identical in all material respects to the
Initial Securities (the "Private Exchange Securities").  The Initial
Securities, the Exchange Securities and the Private Exchange Securities are
herein collectively called the "Securities".

     In connection with the Registered Exchange Offer, the Company shall:

           (a)  mail to each Holder a copy of the prospectus forming part of
     the Exchange Offer Registration Statement, together with an appropriate
     letter of transmittal and related documents;

           (b)  keep the Registered Exchange Offer open for not less than 30
     days (or longer, if required by applicable law) after the date notice
     thereof is mailed to the Holders;

           (c)  utilize the services of a depositary for the Registered
     Exchange Offer with an address in the Borough of Manhattan, The City of
     New York, which may be the Trustee or an affiliate of the Trustee;

           (d)  permit Holders to withdraw tendered Securities at any time
     prior to the close of business, New York time, on the last business day
     on which the Registered Exchange Offer shall remain open; and

           (e)  otherwise comply with all applicable laws.

     As soon as practicable after the close of the Registered Exchange Offer
or the Private Exchange, as the case may be, the Company shall:

           (x) accept for exchange all the Securities validly tendered and
     not withdrawn pursuant to the Registered Exchange Offer and the Private
     Exchange;

           (y) deliver to the Trustee for cancellation all the Initial
     Securities so accepted for exchange; and

           (z) cause the Trustee to authenticate and deliver promptly to each
     Holder of the Initial Securities, Exchange Securities or Private
     Exchange Securities, as the case may be, equal in principal amount to
     the Initial Securities of such Holder so accepted for exchange.

     The Indenture will provide that the Exchange Securities will not be
subject to the transfer restrictions set forth in the Indenture and that all
the Securities will vote and consent together on all matters as one class and
that none of the Securities will have the right to vote or consent as a class
separate from one another on any matter.

     Interest on each Exchange Security and Private Exchange Security issued
pursuant to the Registered Exchange Offer and in the Private Exchange will
accrue from the last interest payment date on which interest was paid on the
Initial Securities surrendered in exchange therefor or, if no interest has
been paid on the Initial Securities, from the date of original issue of the
Initial Securities.

     Each Holder participating in the Registered Exchange Offer shall be
required to represent to the Company that at the time of the consummation of
the Registered Exchange Offer (i) any Exchange Securities received by such
Holder will be acquired in the ordinary course of business, (ii) such Holder
will have no arrangements or understanding with any person to participate in
the distribution of the Securities or the Exchange Securities within the
meaning of the Securities Act, (iii) such Holder is not an "affiliate," as
defined in Rule 405 of the Securities Act, of the Company or if it is an
affiliate, such Holder will comply with the registration and prospectus
delivery requirements of the Securities Act to the extent applicable,
(iv) if such Holder is not a broker-dealer, that it is not engaged in, and
does not intend to engage in, the distribution of the Exchange Securities and
(v) if such Holder is a broker-dealer, that it will receive Exchange
Securities for its own account in exchange for Initial Securities that were
acquired as a result of market-making activities or other trading activities
and that it will be required to acknowledge that it will deliver a prospectus
in connection with any resale of such Exchange Securities.

     Notwithstanding any other provisions hereof, the Company will ensure
that (i) any Exchange Offer Registration Statement and any amendment thereto
and any prospectus forming part thereof and any supplement thereto complies
in all material respects with the Securities Act and the rules and
regulations thereunder, (ii) any Exchange Offer Registration Statement and
any amendment thereto does not, when it becomes effective, contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading and
(iii) any prospectus forming part of any Exchange Offer Registration
Statement, and any supplement to such prospectus, does not include an untrue
statement of a material fact or omit to state 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.

     If following the date hereof there has been announced a change in
Commission policy with respect to exchange offers that in the reasonable
opinion of counsel to the Company raises a substantial question as to whether
the Registered Exchange Offer is permitted by applicable federal law, the
Company will (unless advised in writing by outside counsel that seeking such
no-action letter has no reasonable probability of success) seek a no-action
letter or other favorable decision from the Commission allowing the Company
to consummate the Registered Exchange Offer.  The Company will pursue the
issuance of such a decision to the Commission staff level.  In connection
with the foregoing, the Company will take all such other actions as may be
reasonably requested by the Commission or otherwise reasonably required in
connection with the issuance of such decision, including without limitation
(i) participating in telephonic conferences with the Commission, (ii)
delivering to the Commission staff an analysis prepared by counsel to the
Company setting forth the legal bases, if any, upon which such counsel has
concluded that the Registered Exchange Offer should be permitted and (iii)
diligently pursuing a resolution (which need not be favorable) by the
Commission staff.

     2.  Shelf Registration.  If, (i) because of any change in law or in
applicable interpretations thereof by the staff of the Commission, the
Company is not permitted to effect a Registered Exchange Offer, as
contemplated by Section 1 hereof, (ii) the Registered Exchange Offer is not
consummated by the 210th day after the Closing Date, (iii) any Initial
Purchaser so requests with respect to the Initial Securities (or the Private
Exchange Securities) not eligible to be exchanged for Exchange Securities in
the Registered Exchange Offer and held by it following consummation of the
Registered Exchange Offer or (iv) any Holder (other than an Exchanging
Dealer) is not eligible to participate in the Registered Exchange Offer or,
in the case of any Holder (other than an Exchanging Dealer) that participates
in the Registered Exchange Offer, such Holder does not receive freely
tradeable Exchange Securities on the date of the exchange and any such Holder
so requests, the Company shall take the following actions (the date on which
any of the conditions described in the foregoing clauses (i) through (iv)
occur, including in the case of clauses (iii) or (iv) the receipt of the
required notice, being a "Trigger Date"):

           (a)  The Company shall promptly  (but in no event more than 60
     days after the Trigger Date (such 60th day being a "Filing Deadline"))
     file with the Commission and thereafter use its reasonable best efforts
     to cause to be declared effective no later than 180 days after the
     Trigger Date (such 180th day being an "Effectiveness Deadline") a
     registration statement (the "Shelf Registration Statement" and, together
     with the Exchange Offer Registration Statement, a "Registration
     Statement") on an appropriate form under the Securities Act relating to
     the offer and sale of the Transfer Restricted Securities by the Holders
     thereof from time to time in accordance with the methods of distribution
     set forth in the Shelf Registration Statement and Rule 415 under the
     Securities Act (hereinafter, the "Shelf Registration"); provided,
     however, that no Holder (other than an Initial Purchaser) shall be
     entitled to have the Securities held by it covered by such Shelf
     Registration Statement unless such Holder agrees in writing to be bound
     by all the provisions of this Agreement applicable to such Holder.

           (b)  The Company shall use its reasonable best efforts to keep the
     Shelf Registration Statement continuously effective in order to permit
     the prospectus included therein to be lawfully delivered by the Holders
     of the relevant Securities, for a period of two years (or for such
     longer period if extended pursuant to Section 3(j) below) from the date
     of its effectiveness or such shorter period that will terminate when all
     the Securities covered by the Shelf Registration Statement (i) have been
     sold pursuant thereto or (ii) are no longer subject to limitations under
     clauses (c), (e), (f) and (h) of Rule 144 under the Securities Act, or
     any successor rule thereof (such period being called the "Shelf
     Registration Period").  The Company shall be deemed not to have used its
     reasonable best efforts to keep the Shelf Registration Statement
     effective during the requisite period if it voluntarily takes any
     action that would result in Holders of Securities covered thereby not
     being able to offer and sell such Securities during that period, unless
     the Company shall determine after consulting with outside counsel that
     such action is required by applicable law or otherwise permitted
     hereunder.

           (c)  Notwithstanding any other provisions of this Agreement to the
     contrary, the Company shall cause the Shelf Registration Statement and
     the related prospectus and any amendment or supplement thereto, as of
     the effective date of the Shelf Registration Statement or amendment or
     the filing date of the supplement, (i) to comply in all material
     respects with the applicable requirements of the Securities Act and the
     rules and regulations of the Commission and (ii) other than with respect
     to information included therein in reliance upon and in conformity with
     written information furnished to the Company by or on behalf of any
     Holder specifically for use therein (the "Holders' Information") not to
     contain any untrue statement of a material fact or omit to state a
     material fact required to be stated therein or necessary in order to
     make the statements therein, in light of the circumstances under which
     they were made, not misleading.

     3.  Registration Procedures.  In connection with any Shelf Registration
contemplated by Section 2 hereof and, to the extent applicable, any
Registered Exchange Offer contemplated by Section 1 hereof, the following
provisions shall apply:

           (a)  The Company shall (i) furnish to each Initial Purchaser,
     prior to the filing thereof with the Commission, a copy of the
     Registration Statement and each amendment thereof and each supplement,
     if any, to the prospectus included therein and, in the event that an
     Initial Purchaser (with respect to any portion of an unsold allotment
     from the original offering) is participating in the Registered Exchange
     Offer or the Shelf Registration Statement, the Company shall use its
     reasonable best efforts to reflect in each such document, when so filed
     with the Commission, such comments as such Initial Purchaser reasonably
     may propose; (ii) include the information set forth in Annex A hereto on
     the cover, in Annex B hereto in the "Exchange Offer Procedures" section
     and the "Purpose of the Exchange Offer" section and in Annex C hereto in
     the "Plan of Distribution" section of the prospectus forming a part of
     the Exchange Offer Registration Statement and include the information
     set forth in Annex D hereto in the Letter of Transmittal delivered
     pursuant to the Registered Exchange Offer; (iii) if requested by an
     Initial Purchaser, include the information required by Items 507 or 508
     of Regulation S-K under the Securities Act, as applicable, in the
     prospectus forming a part of the Exchange Offer Registration Statement;
     (iv) include within the prospectus contained in the Exchange Offer
     Registration Statement a section entitled "Plan of Distribution," which
     shall contain a summary statement of the positions taken or policies
     made by the staff of the Commission with respect to the potential
     "underwriter" status of any broker-dealer that is the beneficial owner
     (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as
     amended (the "Exchange Act")) of Exchange Securities received by such
     broker-dealer in the Registered Exchange Offer (a "Participating Broker-
     Dealer"), whether such positions or policies have been publicly
     disseminated by the staff of the Commission or such positions or
     policies, in the reasonable judgment of the Initial Purchasers based
     upon advice of counsel (which may be in-house counsel), represent the
     prevailing views of the staff of the Commission; and (v) in the case of
     a Shelf Registration Statement, to the extent required by the applicable
     Commission staff interpretations, include the names of the Holders who
     propose to sell Securities pursuant to the Shelf Registration Statement
     as selling securityholders.

           (b)  The Company shall give written notice to the Initial
     Purchasers, the Holders of the Securities and any Participating Broker-
     Dealer from whom the Company has received prior written notice that it
     will be a Participating Broker-Dealer in the Registered Exchange Offer
     (which notice pursuant to clauses (ii)-(v) hereof shall be accompanied
     by an instruction to suspend the use of the prospectus until the
     requisite changes have been made):

                (i) when the Registration Statement or any amendment thereto
           has been filed with the Commission and when the Registration
           Statement or any post-effective amendment thereto has become
           effective;

                (ii) of any request by the Commission for amendments or
           supplements to the Registration Statement or the prospectus
           included therein;

                (iii) of the issuance by the Commission of any stop order
           suspending the effectiveness of the Registration Statement or the
           initiation of any proceedings for that purpose;

                (iv) of the receipt by the Company or its legal counsel of
           any notification with respect to the suspension of the
           qualification of the Securities for sale in any jurisdiction
           or the initiation or threatening of any proceeding for such
           purpose; and

                (v) of the happening of any event that requires the Company
           to make changes in the Registration Statement or the prospectus in
           order that the Registration Statement or the prospectus do not
           contain an untrue statement of a material fact nor omit to state a
           material fact required to be stated therein or necessary to make
           the statements therein (in the case of the prospectus, in light of
           the circumstances under which they were made) not misleading,
           provided, the Company will be under no obligation to give notice
           to any person of the specific event that has occurred and shall
           only be required to notify such person that the use of the
           prospectus must be suspended.

           (c)  The Company shall make every reasonable effort to obtain the
     withdrawal at the earliest possible time, of any order suspending the
     effectiveness of the Registration Statement.

           (d)  The Company shall furnish to each Holder of Securities
     included within the coverage of the Shelf Registration, without charge,
     at least one copy of the Shelf Registration Statement and any post-
     effective amendment thereto, including financial statements and
     schedules, and, if the Holder so requests in writing, all exhibits
     thereto (including those, if any, incorporated by reference).

           (e)  The Company shall deliver to each Exchanging Dealer and each
     Initial Purchaser, and to any other Holder who so requests, without
     charge, at least one copy of the Exchange Offer Registration Statement
     and any post-effective amendment thereto, including financial statements
     and schedules, and, if any Initial Purchaser or any such Holder
     requests, all exhibits thereto (including those incorporated by
     reference).

           (f)  The Company shall, during the Shelf Registration Period,
     deliver to each Holder of Securities included within the coverage of the
     Shelf Registration, without charge, as many copies of the prospectus
     (including each preliminary prospectus) included in the Shelf
     Registration Statement and any amendment or supplement thereto as such
     person may reasonably request.  The Company consents, subject to the
     provisions of this Agreement, to the use of the prospectus or any
     amendment or supplement thereto by each of the selling Holders of the
     Securities in connection with the offering and sale of the Securities
     covered by the prospectus, or any amendment or supplement thereto,
     included in the Shelf Registration Statement.

           (g)  The Company shall deliver to each Initial Purchaser, any
     Exchanging Dealer, any Participating Broker-Dealer and such other
     persons required to deliver a prospectus following the Registered
     Exchange Offer, without charge, as many copies of the final prospectus
     included in the Exchange Offer Registration Statement and any amendment
     or supplement thereto as such persons may reasonably request.  The
     Company consents, subject to the provisions of this Agreement, to
     the use of the prospectus or any amendment or supplement thereto by any
     Initial Purchaser, if necessary, any Participating Broker-Dealer and
     such other persons required to deliver a prospectus following the
     Registered Exchange Offer in connection with the offering and sale of
     the Exchange Securities covered by the prospectus, or any amendment or
     supplement thereto, included in such Exchange Offer Registration
     Statement.

           (h)  Prior to any public offering of the Securities pursuant to
     any Registration Statement the Company shall register or qualify or
     cooperate with the Holders of the Securities included therein and their
     respective counsel in connection with the registration or qualification
     of the Securities for offer and sale under the securities or "blue sky"
     laws of such states of the United States as any Holder of the Securities
     reasonably requests in writing and do any and all other acts or things
     necessary or advisable to enable the offer and sale in such
     jurisdictions of the Securities covered by such Registration Statement;
     provided, however, that the Company shall not be required to (i) qualify
     generally to do business in any jurisdiction where it is not then so
     qualified or (ii) take any action which would subject it to general
     service of process or to taxation in any jurisdiction where it is not
     then so subject.(i)  The Company shall cooperate with the Holders of the
     Securities to facilitate the timely preparation and delivery of
     certificates representing the Securities to be sold pursuant to any
     Registration Statement free of any restrictive legends and in such
     denominations and registered in such names as the Holders may request a
     reasonable period of time prior to sales of the Securities pursuant to
     such Registration Statement.

           (j)  Upon the occurrence of any event contemplated by paragraphs
     (ii) through (v) of Section 3(b) above during the period for which the
     Company is required to maintain an effective Registration Statement, the
     Company shall promptly prepare and file a post-effective amendment to
     the Registration Statement or a supplement to the related prospectus and
     any other required document so that, as thereafter delivered to Holders
     of the Securities or purchasers of Securities, the prospectus (other
     than the Holders' Information) will not contain an untrue statement of a
     material fact or omit to state any material fact required to be stated
     therein or necessary to make the statements therein, in light of the
     circumstances under which they were made, not misleading.  If the
     Company notifies the Initial Purchasers, the Holders of the Securities
     and any known Participating Broker-Dealer in accordance with paragraphs
     (ii) through (v) of Section 3(b) above to suspend the use of the
     prospectus until the requisite changes to the prospectus have been made,
     then the Initial Purchasers, the Holders of the Securities and any such
     Participating Broker-Dealers shall suspend use of such prospectus, and
     the period of effectiveness of the Shelf Registration Statement provided
     for in Section 2(b) above and the Exchange Offer Registration Statement
     provided for in Section 1 above shall each be extended by the number of
     days from and including the date of the giving of such notice to and
     including the date when the Initial Purchasers, the Holders of the
     Securities and any known Participating Broker-Dealer shall have received
     such amended or supplemented prospectus pursuant to this Section 3(j);
     provided, however, that such period of effectiveness, including any such
     extension, shall terminate upon the occurrence of any event specified in
     Section 2(b)(i) or Section 2(b)(ii).  Notwithstanding the foregoing, the
     Company shall not be required to file and distribute any such amendment,
     supplement or other required document for a period not to exceed an
     aggregate of 30 days in any calendar year, if (i) an event occurs and is
     continuing as a result of which the Registration Statement would, in the
     Company's good faith judgment, contain an untrue statement of a material
     fact or omit to state a material fact necessary in order to make the
     statements therein, in light of the circumstances in which they were
     made, not misleading and (ii) the board of directors of the Company
     determines in its good faith judgment that the disclosure of such event
     at such time would have a material adverse effect on the business or
     operations of the Company.

           (k)  Not later than the effective date of the applicable
     Registration Statement, the Company will provide a CUSIP number for the
     Initial Securities, the Exchange Securities or the Private Exchange
     Securities, as the case may be, and provide the applicable trustee with
     printed certificates for the Initial Securities, the Exchange Securities
     or the Private Exchange Securities, as the case may be, in a form
     eligible for deposit with The Depository Trust Company.

           (l)  The Company will comply with all rules and regulations of the
     Commission to the extent and so long as they are applicable to the
     Registered Exchange Offer or the Shelf Registration and will make
     generally available to its security holders (or otherwise provide in
     accordance with Section 11(a) of the Securities Act) an earnings
     statement satisfying the provisions of Section 11(a) of the Securities
     Act, no later than 45 days after the end of a 12-month period (or 90
     days, if such period is a fiscal year) beginning with the first month of
     the Company's first fiscal quarter commencing after the effective date
     of the Registration Statement, which statement shall cover such 12-month
     period.

           (m)  The Company shall cause the Indenture to be qualified under
     the Trust Indenture Act of 1939, as amended, in a timely manner and
     containing such changes, if any, as shall be necessary for such
     qualification.  In the event that such qualification would require the
     appointment of a new trustee under the Indenture, the Company shall
     appoint a new trustee thereunder pursuant to the applicable provisions
     of the Indenture.

           (n)  The Company may require each Holder of Securities to be sold
     pursuant to the Shelf Registration Statement to furnish to the Company
     such information regarding the Holder and the distribution of the
     Securities as the Company may from time to time reasonably require for
     inclusion in the Shelf Registration Statement, and the Company may
     exclude from such registration the Securities of any Holder that
     unreasonably fails to furnish such information within a reasonable time
     after receiving such request.

           (o)  The Company shall enter into such customary agreements
     (including, if requested, an underwriting agreement in customary form)
     and take all such other action, if any, as any Holder of the Securities
     shall reasonably request in order to facilitate the disposition of the
     Securities pursuant to any Shelf Registration.

           (p)  In the case of any Shelf Registration, the Company shall (i)
     make reasonably available for inspection by the Holders of the
     Securities, any underwriter participating in any disposition pursuant to
     the Shelf Registration Statement and any attorney, accountant or other
     agent retained by the Holders of the Securities or any such underwriter
     (collectively, the "Inspectors") all relevant financial and other
     records, pertinent corporate documents and properties of the Company and
     (ii) cause the Company's officers, directors, employees, accountants and
     auditors to supply all relevant information reasonably requested by the
     Holders of the Securities or any such underwriter, attorney, accountant
     or agent in connection with the Shelf Registration Statement, in each
     case, as shall be reasonably necessary to enable such persons, to
     conduct a reasonable investigation within the meaning of Section 11 of
     the Securities Act; provided, however, that the foregoing inspection and
     information gathering shall be coordinated on behalf of the Initial
     Purchasers by you and on behalf of the other parties, by one counsel
     designated by and on behalf of such other parties as described in
     Section 4 hereof.  Records which the Company reasonably determines, in
     good faith, to be confidential and any records which they notify the
     Inspectors are confidential shall not be disclosed by the Inspectors
     unless (i) the disclosure of such records is necessary to avoid or
     correct a material misstatement or omission in such Registration
     Statement after a failure by the Company to make such disclosure for a
     period of 5 business days after receiving written notice from any
     Inspector of the need to make such disclosure, (ii) the release of such
     records is ordered pursuant to a subpoena or other order from a court of
     competent jurisdiction or (iii) the information in such records has been
     made generally available to the public.  Each selling Holder of such
     Registrable Securities and each such Participating Broker-Dealer will
     be required to agree that information obtained by it as a result of such
     inspections shall be deemed confidential, shall be used solely in
     connection with the transactions contemplated herein and shall not be
     used by it as the basis for any market transactions in the securities of
     the Company unless and until such is made generally available to the
     public.  Each selling Holder of such Registrable Securities and each
     such Participating Broker-Dealer will be required to further agree that
     it will, upon learning that disclosure of such records is sought in a
     court of competent jurisdiction, give notice to the Company and allow
     the Company at its expense to undertake appropriate action to prevent
     disclosure of the records deemed confidential.

           (q)  In the case of any Shelf Registration, the Company, if
     requested by Holders of a majority in aggregate principal amount of the
     Securities covered thereby, shall cause (i) its counsel to deliver an
     opinion and updates thereof relating to the Securities in customary form
     addressed to such Holders and the managing underwriters, if any, thereof
     and dated, in the case of the initial opinion, the effective date of
     such Shelf Registration Statement, which opinions shall cover matters
     customarily addressed in opinions requested by underwriters in
     connection with underwritten offerings; (ii) its officers to execute and
     deliver customary documents and certificates and updates thereof
     reasonably requested by any underwriters of the applicable Securities
     and (iii) its independent public accountants to provide to the selling
     Holders of the applicable Securities and any underwriter therefor a
     comfort letter in customary form and covering matters of the type
     customarily covered in comfort letters in connection with primary
     underwritten offerings, subject to receipt of appropriate documentation
     as contemplated, and only if permitted, by Statement of Auditing
     Standards No. 72.

           (r)  In the case of the Registered Exchange Offer, if requested by
     any Initial Purchaser or any known Participating Broker-Dealer, the
     Company shall cause (i) its counsel to deliver to such Initial Purchaser
     or such Participating Broker-Dealer signed opinions in the form set
     forth in Sections 6(c) and 6(d) of the Purchase Agreement with such
     changes as are customary in connection with the preparation of a
     Registration Statement and (ii) its independent public accountants and
     the independent public accountants with respect to any other entity for
     which financial information is provided in the Registration Statement to
     deliver to such Initial Purchaser or such Participating Broker-Dealer a
     comfort letter, in customary form, meeting the requirements as to the
     substance thereof as set forth in Section 6(a) and (g) of the Purchase
     Agreement, with appropriate date changes.

           (s)  If a Registered Exchange Offer or a Private Exchange is to be
     consummated, upon delivery of the Initial Securities by Holders to the
     Company (or to such other Person as directed by the Company) in exchange
     for the Exchange Securities or the Private Exchange Securities, as the
     case may be, the Company shall mark, or caused to be marked, on the
     Initial Securities so exchanged that such Initial Securities are being
     canceled in exchange for the Exchange Securities or the Private Exchange
     Securities, as the case may be; in no event shall the Initial Securities
     be marked as paid or otherwise satisfied.

           (t)  The Company will use its best efforts to (a) if the Initial
     Securities have been rated prior to the initial sale of such Initial
     Securities, confirm such ratings will apply to the Securities covered by
     a Registration Statement, or (b) if the Initial Securities were not
     previously rated, cause the Securities covered by a Registration
     Statement to be rated with the appropriate rating agencies, if so
     requested by Holders of a majority in aggregate principal amount of
     Securities covered by such Registration Statement, or by the managing
     underwriters, if any.

           (u)  In the event that any broker-dealer registered under the
     Exchange Act shall underwrite any Securities or participate as a member
     of an underwriting syndicate or selling group or "assist in the
     distribution" (within the meaning of the Conduct Rules (the "Rules") of
     the National Association of Securities Dealers, Inc. ("NASD")) thereof,
     whether as a Holder of such Securities or as an underwriter, a placement
     or sales agent or a broker or dealer in respect thereof, or otherwise,
     the Company will assist such broker-dealer in complying with the
     requirements of such Rules, including, without limitation, by (i) if
     such Rules, including Rule 2720, shall so require, engaging a "qualified
     independent underwriter" (as defined in Rule 2720) to participate in the
     preparation of the Registration Statement relating to such Securities,
     to exercise usual standards of due diligence in respect thereto and, if
     any portion of the offering contemplated by such Registration Statement
     is an underwritten offering or is made through a placement or sales
     agent, to recommend the yield of such Securities, (ii) indemnifying any
     such qualified independent underwriter to the extent of the
     indemnification of underwriters provided in Section 5 hereof and (iii)
     providing such information to such broker-dealer as may be required in
     order for such broker-dealer to comply with the requirements of the
     Rules.

           (v)  The Company shall use its reasonable best efforts to take all
     other steps necessary to effect the registration of the Securities
     covered by a Registration Statement contemplated hereby.

4.  Registration Expenses.

      (a)  All expenses incident to the Company's performance of and
compliance with this Agreement will be borne by the Company, regardless
of whether a Registration Statement is ever filed or becomes effective,
including without limitation;

           (i) all registration and filing fees and expenses;

           (ii) all fees and expenses of compliance with federal securities
      and state "blue sky" or securities laws;

           (iii) all expenses of printing (including printing
      certificates for the Securities to be issued in the Registered
      Exchange Offer and the Private Exchange and printing of
      Prospectuses), messenger and delivery services and telephone;

           (iv) all fees and disbursements of counsel for the Company;

           (v) all application and filing fees in connection with
      listing the Exchange Securities on a national securities exchange
      or automated quotation system pursuant to the requirements hereof;
      and

           (vi) all fees and disbursements of independent certified public
      accountants of the Company (including the expenses of any special audit
      and comfort letters required by or incident to such performance).

     In connection with any Registration Statement required by this
Agreement, in no event shall the Company be responsible for any underwriting
discounts or commissions or brokerage fees or fees and disbursements of
counsel for any underwriter or commissions or brokerage fees incurred by the
selling Holders in connection with a Shelf Registration Statement.  The
Company will bear its internal expenses (including, without limitation, all
salaries and expenses of its officers and employees performing legal or
accounting duties), the expenses of any annual audit and the fees and
expenses of any person, including special experts, retained by the Company.
The Holders participating in any underwritten offering shall be responsible
for any underwriting discounts and commissions and fees and disbursements of
counsel to the selling Holders to the extent not required to be paid by the
Company pursuant to this Agreement.

      (b)  In connection with any Registration Statement required by this
Agreement, the Company will reimburse the Initial Purchasers and the Holders
of Transfer Restricted Securities who are tendering Initial Securities in the
Registered Exchange Offer or selling or reselling Securities pursuant to the
"Plan of Distribution" contained in the Exchange Offer Registration Statement
or the Shelf Registration Statement, as applicable, for the reasonable fees
and disbursements not to exceed $50,000 of not more than one counsel, who
shall be Cravath, Swaine & Moore unless another firm shall be chosen by the
Holders of a majority in principal amount of the Transfer Restricted
Securities for whose benefit such Registration Statement is being prepared.

5.  Indemnification.

      (a)  The Company agrees to indemnify and hold harmless each Holder of
the Securities, any Participating Broker-Dealer and each person, if any, who
controls such Holder or such Participating Broker-Dealer within the meaning
of the Securities Act or the Exchange Act (each Holder, any Participating
Broker-Dealer and such controlling persons are referred to collectively as
the "Indemnified Parties") from and against any losses, claims, damages or
liabilities, joint or several, or any actions in respect thereof (including,
but not limited to, any losses, claims, damages, liabilities or actions
relating to purchases and sales of the Securities) to which each Indemnified
Party may become subject under the Securities Act, the Exchange Act or
otherwise, insofar as such losses, claims, damages, liabilities or actions
arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in a Registration Statement or
prospectus or in any amendment or supplement thereto or in any preliminary
prospectus relating to a Shelf Registration, or arise out of, or are based
upon, the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, and shall reimburse, as incurred, the Indemnified Parties for any
legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action
in respect thereof; provided, however, that (i) the Company shall not be
liable in any such case to the extent that such loss, claim, damage or
liability arises out of or is based upon any untrue statement or alleged
untrue statement or omission or alleged omission made in a Registration
Statement or prospectus or in any amendment or supplement thereto or in any
preliminary prospectus relating to a Shelf Registration in reliance upon and
in conformity with written information pertaining to such Holder and
furnished to the Company by or on behalf of such Holder specifically for
inclusion therein and (ii) with respect to any untrue statement or omission
or alleged untrue statement or omission made in any preliminary prospectus
relating to a Shelf Registration Statement, the indemnity agreement contained
in this subsection (a) shall not inure to the benefit of any Holder or
Participating Broker-Dealer from whom the person asserting any such losses,
claims, damages or liabilities purchased the Securities concerned, to the
extent that a prospectus relating to such Securities was required to be
delivered by such Holder or Participating Broker-Dealer under the Securities
Act in connection with such purchase and any such loss, claim, damage or
liability of such Holder or Participating Broker-Dealer results from the fact
that there was not sent or given to such person, at or prior to the written
confirmation of the sale of such Securities to such person, a copy of the
final prospectus if the Company had previously furnished copies thereof to
such Holder or Participating Broker-Dealer; provided further, however, that
this indemnity agreement will be in addition to any liability which the
Company may otherwise have to such Indemnified Party.  The Company shall also
indemnify underwriters, their officers and directors and each person who
controls such underwriters within the meaning of the Securities Act or the
Exchange Act to the same extent as provided above with respect to the
indemnification of the Holders of the Securities if requested by such
Holders.

      (b)  Each Holder of the Securities, severally and not jointly, will
indemnify and hold harmless the Company and each person, if any, who controls
the Company within the meaning of the Securities Act or the Exchange Act from
and against any losses, claims, damages or liabilities or any actions in
respect thereof, to which the Company or any such controlling person may
become subject under the Securities Act, the Exchange Act or otherwise,
insofar as such losses, claims, damages, liabilities or actions arise out of
or are based upon any untrue statement or alleged untrue statement of a
material fact contained in a Registration Statement or prospectus or in any
amendment or supplement thereto or in any preliminary prospectus relating to
Shelf Registration, or arise out of or are based upon the omission or alleged
omission to state therein a material fact necessary to make the statements
therein not misleading, but in each case only to the extent that the untrue
statement or omission or alleged untrue statement or omission was made in
reliance upon and in conformity with written information pertaining to such
Holder and furnished to the Company by or on behalf of such Holder
specifically for inclusion therein; and, subject to the limitation set forth
immediately preceding this clause, shall reimburse, as incurred, the Company
for any legal or other expenses reasonably incurred by the Company or any
such controlling person in connection with investigating or defending any
loss, claim, damage, liability or action in respect thereof.  This indemnity
agreement will be in addition to any liability which such Holder may
otherwise have to the Company or any of its controlling persons.

      (c)  Promptly after receipt by an indemnified party under this Section
5 of notice of the commencement of any action or proceeding (including a
governmental investigation), such indemnified party will, if a claim in
respect thereof is to be made against the indemnifying party under this
Section 5, notify the indemnifying party of the commencement thereof; but the
failure to notify the indemnifying party shall not relieve it from any
liability that it may have under subsection (a) or (b) above except to the
extent that it has been materially prejudiced (through the forfeiture of
substantive rights or defenses) by such failure; and provided further that
the failure to notify the indemnifying party shall not relieve it from any
liability that it may have to an indemnified party otherwise than under
subsection (a) or (b) above.  In case any such action is brought against any
indemnified party, and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate therein and,
to the extent that it may wish, jointly with any other indemnifying party
similarly notified, to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified party (who shall not, except with the
consent of the indemnified party, be counsel to the indemnifying party), and
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof the indemnifying party will not be
liable to such indemnified party under this Section 5 for any legal or other
expenses, other than reasonable costs of investigation, subsequently incurred
by such indemnified party in connection with the defense thereof.  No
indemnifying party shall, without the prior written consent of the
indemnified party, effect any settlement of any pending or threatened action
in respect of which any indemnified party is or could have been a party and
indemnity could have been sought hereunder by such indemnified party unless
such settlement (i) includes an unconditional release of such indemnified
party from all liability on any claims that are the subject matter of such
action, and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act by or on behalf of any indemnified party.

      (d)  If the indemnification provided for in this Section 5 is
unavailable or insufficient to hold harmless an indemnified party under
subsections (a) or (b) above, then each indemnifying party shall contribute
to the amount paid or payable by such indemnified party as a result of the
losses, claims, damages or liabilities (or actions in respect thereof)
referred to in subsection (a) or (b) above in such proportion as is
appropriate to reflect the relative fault of the indemnifying party or
parties on the one hand and the indemnified party on the other in connection
with the statements or omissions that resulted in such losses, claims,
damages or liabilities (or actions in respect thereof) as well as any other
relevant equitable considerations.  The relative fault of the parties shall
be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the
Company on the one hand or such Holder or such other indemnified party, as
the case may be, on the other, and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.  The amount paid by an indemnified party as a result of the losses,
claims, damages or liabilities referred to in the first sentence of this
subsection (d) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with
investigating or defending any action or claim which is the subject of this
subsection (d).  Notwithstanding any other provision of this Section 5(d),
the Holders of the Securities shall not be required to contribute any amount
in excess of the amount by which the net proceeds received by such Holders
from the sale of the Securities pursuant to a Registration Statement exceeds
the amount of damages which such Holders have otherwise been required to pay
by reason of such untrue or alleged untrue statement or omission or alleged
omission.  No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.  For purposes of this paragraph (d), each person, if any,
who controls such indemnified party within the meaning of the Securities Act
or the Exchange Act shall have the same rights to contribution as such
indemnified party and each person, if any, who controls the Company within
the meaning of the Securities Act or the Exchange Act shall have the same
rights to contribution as the Company.

      (e)  The agreements contained in this Section 5 shall survive the sale
of the Securities pursuant to a Registration Statement and shall remain in
full force and effect, regardless of any termination or cancellation of this
Agreement or any investigation made by or on behalf of any indemnified party.

6.  Additional Interest Under Certain Circumstances.

      (a)  Additional interest (the "Additional Interest") with respect to
the Securities shall be assessed as follows if any of the following events
occur (each such event in clauses (i) through (iv) below being herein called
a "Registration Default"):

           (i) any Registration Statement required by this Agreement is not
      filed with the Commission on or prior to the applicable Filing
      Deadline;

           (ii) any Registration Statement required by this Agreement is
      not declared effective by the Commission on or prior to the applicable
      Effectiveness Deadline;

           (iii) the Registered Exchange Offer has not been consummated on or
      prior to the Consummation Deadline; or

           (iv) any Registration Statement required by this Agreement has
      been declared effective by the Commission but (A) such Registration
      Statement thereafter ceases to be effective or (B) such Registration
      Statement or the related prospectus ceases to be usable (except as
      permitted in paragraph (b)) in connection with resales of Transfer
      Restricted Securities during the periods specified herein because
      either (1) any event occurs as a result of which the related prospectus
      forming part of such Registration Statement would include any untrue
      statement of a material fact or omit to state any material fact
      necessary to make the statements therein in the light of the
      circumstances under which they were made not misleading, or (2) it
      shall be necessary to amend such Registration Statement or supplement
      the related prospectus, to comply with the Securities Act or the
      Exchange Act or the respective rules thereunder.

Each of the foregoing will constitute a Registration Default whatever the
reason for any such event and whether it is voluntary or involuntary or is
beyond the control of the Company or pursuant to operation of law or as a
result of any action or inaction by the Commission .

Additional Interest shall accrue on the Securities over and above the
interest set forth in the title of the Securities from and including the date
on which any such Registration Default shall occur to but excluding the date
on which all such Registration Defaults have been cured, at a rate of 0.50%
per annum (the "Additional Interest Rate") for the first 90-day period
immediately following the occurrence of such Registration Default.  The
Additional Interest Rate shall increase by an additional 0.50% per annum with
respect to each subsequent 90-day period until all Registration Defaults have
been cured, up to a maximum Additional Interest Rate of 2.0% per annum.

      (b)  A Registration Default referred to in Section 6(a)(iv) hereof
shall be deemed not to have occurred and be continuing in relation to a Shelf
Registration Statement or the related prospectus if (i) such Registration
Default has occurred solely as a result of (x) the filing of a post-effective
amendment to such Shelf Registration Statement to incorporate annual audited
financial information with respect to the Company where such post-effective
amendment is not yet effective and needs to be declared effective to permit
Holders to use the related prospectus or (y) other material events, with
respect to the Company that would need to be described in such Shelf
Registration Statement or the related prospectus and (ii) in the case of
clause (y), subject to Section 3(j), the Company is proceeding promptly and
in good faith to amend or supplement such Shelf Registration Statement and
related prospectus to describe such events; provided, however, that in any
case if such Registration Default occurs for a continuous period in excess of
45 days, Additional Interest shall be payable in accordance with the above
paragraph from the day such Registration Default occurs until such
Registration Default is cured.

      (c)  Any amounts of Additional Interest due pursuant to Section 6(a)
will be payable in cash on the regular interest payment dates with respect to
the Securities.  The amount of Additional Interest will be determined by
multiplying the applicable Additional Interest Rate by the principal amount
of the Securities and further multiplied by a fraction, the numerator of
which is the number of days such Additional Interest Rate was applicable
during such period (determined on the basis of a 360-day year comprised of
twelve 30-day months), and the denominator of which is 360.

      (d)  "Transfer Restricted Securities" means each Security until (i) the
date on which such Security has been exchanged by a person other than a
broker-dealer for a freely transferable Exchange Security in the Registered
Exchange Offer, (ii) following the exchange by a broker-dealer in the
Registered Exchange Offer of an Initial Security for an Exchange Note, the
date on which such Exchange Note is sold to a purchaser who receives from
such broker-dealer on or prior to the date of such sale a copy of the
prospectus contained in the Exchange Offer Registration Statement, (iii) the
date on which such Security has been effectively registered under the
Securities Act and disposed of in accordance with the Shelf Registration
Statement or (iv) the date on which such Security is distributed to the
public pursuant to Rule 144 under the Securities Act or is saleable pursuant
to Rule 144(k) under the Securities Act.

     7.  Rules 144 and 144A.  The Company shall use its best efforts to file
the reports required to be filed by it under the Securities Act and the
Exchange Act in a timely manner and, if at any time the Company is not
required to file such reports, it will, upon the request of any Holder of
Securities, make publicly available other information so long as necessary to
permit sales of their securities pursuant to Rules 144 and 144A.  The Company
covenants that it will take such further action as any Holder of Securities
may reasonably request, all to the extent required from time to time to
enable such Holder to sell Securities without registration under the
Securities Act within the limitation of the exemptions provided by Rules 144
and 144A (including the requirements of Rule 144A(d)(4)).  The Company will
provide a copy of this Agreement to prospective purchasers of Initial
Securities identified to the Company by the Initial Purchasers upon request.
Upon the request of any Holder of Initial Securities, the Company shall
deliver to such Holder a written statement as to whether it has complied with
such requirements.  Notwithstanding the foregoing, nothing in this Section 7
shall be deemed to require the Company to register any of its securities
pursuant to the Exchange Act.

     8.  Underwritten Registrations.  If any of the Transfer Restricted
Securities covered by any Shelf Registration are to be sold in an
underwritten offering, the investment banker or investment bankers and
manager or managers that will administer the offering ("Managing
Underwriters") will be selected by the Holders of a majority in aggregate
principal amount of such Transfer Restricted Securities to be included in
such offering, subject to the approval of the Company (which shall not be
unreasonably withheld); provided that at least 10% of the outstanding
Transfer Restricted Securities are included in such underwritten offering.
The Company shall not be obligated to arrange for more than two underwritten
offerings during the Shelf Registration Period. No person may participate in
any underwritten registration hereunder unless such person (i) agrees to sell
such person's Transfer Restricted Securities on the basis reasonably provided
in any underwriting arrangements approved by the persons entitled hereunder
to approve such arrangements and (ii) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents reasonably required under the terms of such underwriting
arrangements.

     9.  Miscellaneous.

           (a)  Remedies.  The Company acknowledges and agrees that any
     failure by the Company to comply with its obligations under Section 1
     and 2 hereof may result in material irreparable injury to the Initial
     Purchasers or the Holders for which there is no adequate remedy at law,
     that it will not be possible to measure damages for such injuries
     precisely and that, in the event of any such failure, the Initial
     Purchasers or any Holder may obtain such relief as may be required to
     specifically enforce the Company's obligations under Sections 1 and 2
     hereof.  The Company further agrees to waive the defense in any action
     for specific performance that a remedy at law would be adequate.

           (b)  No Inconsistent Agreements.  The Company will not on or after
     the date of this Agreement enter into any agreement with respect to its
     securities that is inconsistent with the rights granted to the Holders
     in this Agreement or otherwise conflicts with the provisions hereof.
     The rights granted to the Holders hereunder do not in any way conflict
     with and are not inconsistent with the rights granted to the holders of
     the Company's securities under any agreement in effect on the date
     hereof.

           (c)  Amendments and Waivers.  The provisions of this Agreement may
     not be amended, modified or supplemented, and waivers or consents to
     departures from the provisions hereof may not be given, except by the
     Company and the written consent of the Holders of a majority in
     principal amount of the Securities affected by such amendment,
     modification, supplement, waiver or consents.  Without the consent of
     the Holder of each Security, however, no modification may change the
     provisions relating to the payment of Additional Interest.

           (d)  Notices.  All notices and other communications provided for
     or permitted hereunder shall be made in writing by hand delivery, first-
     class mail, facsimile transmission, or air courier which guarantees

herein, or the application thereof in any circumstance, is held invalid,
illegal or unenforceable, the validity, legality and enforceability of any
such provision in every other respect and of the remaining provisions
contained herein shall not be affected or impaired thereby.

      (k)  Securities Held by the Company.  Whenever the consent or approval
of Holders of a specified percentage of principal amount of Securities is
required hereunder, Securities held by the Company or its affiliates (other
than subsequent Holders of Securities if such subsequent Holders are deemed
to be affiliates solely by reason of their holdings of such Securities) shall
not be counted in determining whether such consent or approval was given by
the Holders of such required percentage.

      (l)  Submission to Jurisdiction; Waiver of Immunities.  By the
execution and delivery of this Agreement, the Company submits to the
nonexclusive jurisdiction of any federal or state court in the State of New
York in any suit or proceeding arising out of or relating to this Agreement
that may be instituted in or brought under federal or state securities laws.
To the extent that the Company may acquire any immunity from jurisdiction of
any court or from any legal process (whether through service of notice,
attachment prior to judgment, attachment in aid of execution, execution or
otherwise) with respect to itself or its property, it hereby irrevocably
waives such immunity in respect of this Agreement, to the fullest extent
permitted by law.


     If the foregoing is in accordance with your understanding of our
agreement, please sign and return to the Company a counterpart hereof,
whereupon this instrument, along with all counterparts, will become a binding
agreement among the several Initial Purchasers and the Company in accordance
with its terms.

   Title: Director


ANNEX A Each broker-dealer that receives Exchange Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities.
