As Representatives of the several Purchasers,
    c/o Credit Suisse First Boston Corporation
        Eleven Madison Avenue
        New York, N.Y. 10010-3629

Dear Sirs:

         1. Introductory. AmerisourceBergen Corporation, 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. $300,000,000 principal amount of its 7 1/4% Senior Notes due
2012 (the "Offered Securities"), to be issued under an indenture, dated as of
November 18, 2002 (the "Indenture"), among the Company, each of the subsidiary
guarantors named in Schedule D hereto (the "Guarantors") and J.P. Morgan Trust
Company, National Association, as Trustee. The Offered Securities will be
guaranteed by each of the Guarantors, who will enter into a notation of
guarantee (each, a "Notation of Guarantee" and together, the "Subsidiary
Guarantees") pursuant to the terms of the Indenture. As a result of the
Subsidiary Guarantees, the Offered Securities will be unconditionally guaranteed
on a senior unsecured basis as to payment of principal, premium, if any,
liquidated damages, if any, and interest by each of the Guarantors. The United
States Securities Act of 1933 is herein referred to as the "Securities Act."

         Holders (including subsequent transferees) of the Offered Securities
will have the registration rights set forth in the registration rights agreement
(the "Registration Rights Agreement"), to be dated the Closing Date, in
substantially the form of Exhibit I hereto, for so long as such Offered
Securities constitute "Transfer Restricted Securities" (as defined in the
Registration Rights Agreement). Pursuant to the Registration Rights Agreement,
the Company and the Guarantors will agree to file with the Securities and
Exchange Commission (the "Commission") under the circumstances set forth
therein, (i) a registration statement under the Securities Act (the "Exchange
Offer Registration Statement") relating to the Company's 7 1/4% Senior Notes due
2012 (the "Exchange Securities"), in a like aggregate principal amount as the
Company issued under the Indenture

<PAGE>

and guarantees thereof by the Guarantors (the "Exchange Security Guarantee"),
identical in all material respects to the Offered Securities and the Subsidiary
Guarantees and registered under the Securities Act to be offered in exchange for
the Offered Securities (such offer to exchange being referred to as the
"Exchange Offer") and the Subsidiary Guarantees thereof and (ii) a shelf
registration statement pursuant to Rule 415 under the Securities Act (the "Shelf
Registration Statement" and, together with the Exchange Offer Registration
Statement, the "Registration Statements") relating to the resale by certain
holders of the Offered Securities and to use its best efforts to cause such
Registration Statements to be declared and remain effective and usable for the
periods specified in the Registration Rights Agreement and to consummate the
Exchange Offer. The Offered Securities, the Exchange Securities, the Subsidiary
Guarantees and the Exchange Security Guarantees are referred to collectively as
the "Securities."

         The Company hereby agrees with the several Purchasers as follows:

         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 to be offered by the Purchasers 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, are
         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 Corporation ("CSFBC")
         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 "Compensation of Directors," "Security Ownership of
         Certain Beneficial Owners and Management," "Management" and "Certain
         Transactions" sections from the proxy statement of the Company filed on
         Form DEF 14A on January 23, 2002, the "Legal Matters and Contingencies"
         section from the quarterly report of the Company filed on Form 10-Q on

         (the "Commission") and all subsequent reports (collectively, the

         Act of 1934 (the "Exchange Act") 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) The Company has been duly incorporated and is an existing

         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 to the extent that the failure to be so qualified
         or in good standing would not have a material adverse effect on the
         condition (financial or other), business, properties or result of
         operations of the Company and its subsidiaries, taken as a whole (a
         "Material Adverse Effect").

         Offering Document; and each subsidiary of the Company is duly
         qualified to do business as a foreign corporation in good standing in

         extent that the failure to be so qualified or in good standing 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, except for any lien or encumbrance on such capital stock to
         secure the Company's obligations under the Credit Agreement (as

         and regulations of the Commission applicable to an indenture which is
         qualified thereunder.

                 (f) Except as disclosed in the Offering Document, or as
         contemplated by this Agreement, there are no contracts, agreements or
         understandings between the Company and any person that would give rise
         to a valid claim against the Company or any Purchaser for a brokerage
         commission, finder's fee or other like payment in connection with the
         offer and sale of the Offered Securities.

         assigned or (b) any change in the outlook for any rating of the
         Company, any Guarantor or any securities of the Company or any
         Guarantor.

                  (aa) No form of general solicitation or general advertising
         (as defined in Regulation D under the Securities Act) was used by the
         Company, the Guarantors or any of their respective representatives
         (other than the Purchasers, as to whom the Company and the Guarantors
         make no representation) in connection with the offer and sale of the
         Offered Securities contemplated hereby, including, but not limited to,
         articles, notices or other communications published in any newspaper,
         magazine, or similar medium or broadcast over television or radio, or
         any seminar or meeting whose attendees have been invited by any general
         solicitation or general advertising. No securities of the same class as
         the Offered Securities have been issued and sold by the Company within
         the six-month period immediately prior to the date hereof.

                  (bb) None of the Company, the Guarantors nor any of their
         respective affiliates or any person acting on its or their behalf
         (other than the Purchasers, as to whom the Company and the Guarantors
         make no representation) has engaged or will engage in any directed
         selling efforts within the meaning of Regulation S under the Securities
         Act ("Regulation S") with respect to the Offered Securities or the
         Subsidiary Guarantees.

                  (cc) Assuming the accuracy of the Purchaser's representations
         set forth in Section 4 hereof, the offer and sale by the Company and
         the Guarantors of the Offered Securities and the Subsidiary Guarantees,
         respectively, in the manner contemplated by this Agreement, to the
         Purchasers and the Exempt Resales will be exempt from the registration
         requirements of the Securities Act by reason of Section 4(2) thereof
         and Regulation S thereunder; and it is not necessary to qualify an
         indenture in respect of the Offered Securities under the United States
         Trust Indenture Act of 1939, as amended (the "Trust Indenture Act").

                  (dd) None of the Company, the Guarantors nor any of their
         respective affiliates or any person acting on its or their behalf
         (other than the Purchasers, as to whom the Company and the Guarantors
         make no representation) has offered or sold, or will offer or sell, the
         Offered Securities in reliance on Regulation S other than in offshore
         transactions.

                  (ee) The sale of the Offered Securities pursuant to Regulation
         S is not part of a plan or scheme by the Company, the Guarantors or any
         of their respective affiliates or any person acting on its or their
         behalf (other than the Purchasers, as to whom the Company and the
         Guarantors make no representation) to evade the registration provisions
         of the Securities Act.

                  (ff) Neither the Company, nor any of its affiliates (as
         defined in Rule 501(b) of Regulation D), nor any person acting on its
         or their behalf (other than the Purchasers, as to whom the Company and
         the Guarantors make no representation) (i) has, within the six-month
         period prior to the date hereof, offered or sold in the United States
         or to any U.S. person (as such terms are defined in Regulation S under
         the Securities Act) the Offered Securities, or any security of the same
         class or series as the Offered Securities or (ii) has offered or will
         offer or sell the Offered Securities (A) in the United States by means
         of any form of general solicitation or general advertising within the
         meaning of Rule 502(c) under the Securities Act or (B) with respect to
         any such securities sold in reliance on Rule 903 of Regulation S
         ("Regulation S") under the Securities Act, by means of any directed
         selling efforts within the meaning of Rule 902(c) of Regulation S. The
         Company, its affiliates and any person acting on its or their behalf
         have complied and will comply with the offering restrictions
         requirement of Regulation S, provided, however, that no representation
         is made with respect to compliance by the Purchasers with the offering
         restrictions requirement of Regulation S. The Company has not entered
         and will not enter into any contractual arrangement with respect to the
         distribution of the Offered Securities except for this Agreement.

                  (gg) The proceeds to the Company from the offering of the
         Offered Securities will not be used to purchase or carry any security
         except as set forth in the Offering Document.

                  (hh) The Company is subject to Section 13 or 15(d) of the
         Exchange Act.

         4.  Representations by Purchasers; Resale by Purchasers.

                  (a)  Each Purchaser severally represents and warrants to the
         Company that it is an "accredited investor" within the meaning of
         Regulation D under the Securities Act.

                  (b)  Each Purchaser severally acknowledges that the Offered
         Securities have not been registered under the Securities Act and may
         not be offered or sold within the United States or to, or for the
         account or benefit of, U.S. persons except in accordance with
         Regulation S or pursuant to an exemption from the registration
         requirements of the Securities Act. Each Purchaser severally represents
         and agrees that it has offered and sold the Offered Securities, and
         will offer and sell the Offered Securities (i) as part of its
         distribution at any time and (ii) otherwise until 40 days after the
         later of the commencement of the offering and the latest Closing Date,
         only in accordance with Rule 903 or Rule 144A under the Securities Act
         ("Rule 144A"). Accordingly, neither such Purchaser nor its affiliates,
         nor any persons acting on its or their behalf, have engaged or will
         engage in any directed selling efforts with respect to the Offered
         Securities, and such Purchaser, its affiliates and all persons acting
         on its or their behalf have complied and will comply with the offering
         restrictions requirement of Regulation S. Each Purchaser severally
         agrees that, at or prior to confirmation of sale of the Offered
         Securities, other than a sale pursuant to Rule 144A, such Purchaser
         will have sent to each distributor, dealer or person receiving a
         selling concession, fee or other remuneration that purchases the
         Offered Securities from it during the restricted period a confirmation
         or notice to substantially the following effect:

                  "The Securities covered hereby have not been registered under
                  the U.S. Securities Act of 1933 (the "Securities Act") and may
                  not be offered or sold within the United States or to, or for
                  the account or benefit of, U.S. persons (i) as part of their
                  distribution at any time or (ii) otherwise until 40 days after
                  the later of the date of the commencement of the offering and
                  the closing date, except in either case in accordance with
                  Regulation S (or Rule 144A if available) under the Securities
                  Act. Terms used above have the meanings given to them by
                  Regulation S."

                                       8

<PAGE>

         Terms used in this subsection (b) have the meanings given to them by
         Regulation S.

                  (c)  Each Purchaser severally acknowledges that the Offered
         Securities have not been registered under the Securities Act and may
         not be offered or sold within the United States or to, or for the
         account or benefit of, U.S. persons except in accordance with
         Regulation S or pursuant to an exemption from the registration
         requirements of the Securities Act. Each Purchaser severally represents
         and agrees that it has offered and sold the Offered Securities, and
         will offer and sell the Offered Securities only in accordance with Rule
         903 or Rule 144A under the Securities Act ("Rule 144A"). Accordingly,
         neither such Purchaser nor its affiliates, nor any persons acting on
         its or their behalf, have engaged or will engage in any directed
         selling efforts with respect to the Offered Securities, and such
         Purchaser, its affiliates and all persons acting on its or their behalf
         have complied and will comply with the offering restrictions
         requirement of Regulation S and Rule 144A.

                  (d)  Each Purchaser severally agrees that it and each of its
         affiliates has not entered and will not enter into any contractual
         arrangement with respect to the distribution of the Offered Securities
         except for any such arrangements with the other Purchasers or
         affiliates of the other Purchasers or with the prior written consent of
         the Company.

                  (e)  Each Purchaser severally agrees that it and each of its
         affiliates will not offer or sell the Offered Securities in the United
         States by means of any form of general solicitation or general
         advertising within the meaning of Rule 502(c) under the Securities Act,
         including, but not limited to (i) any advertisement, article, notice or
         other communication published in any newspaper, magazine or similar
         media or broadcast over television or radio, or (ii) any seminar or
         meeting whose attendees have been invited by any general solicitation
         or general advertising. Each Purchaser severally agrees, with respect
         to resales made in reliance on Rule 144A of any of the Offered
         Securities, to deliver either with the confirmation of such resale or
         otherwise prior to settlement of such resale a notice to the effect
         that the resale of such Offered Securities has been made in reliance
         upon the exemption from the registration requirements of the Securities
         Act provided by Rule 144A.

                  (f)  Each of the Purchasers severally represents and agrees
         that (i) it has not authorized the Offered Securities to be offered to
         the public in the United Kingdom, within the meaning of the Public
         Offers of Securities Regulation 1995, as amended; (ii) it has only
         issued and passed on and will only issue and pass on in the United
         Kingdom the Offering Document or any other document issued in
         connection with the sale of the Offered Securities, to a person who is
         of a kind described in Article 19 of the Financial Services and Markets
         Act 2000 (Financial Promotion) Order 2001 or is a person to whom the
         document may otherwise lawfully be issued or passed on; (iii) to the
         extent it has directed the Offering Document to persons in the United
         Kingdom, it has only directed the Offering Document at persons having
         professional experience in matters relating to investments and it will
         only make the offering described in the Offering Document available to
         such persons and only such persons will be permitted to participate in
         the offering; and (iv) it has complied and will comply with all
         applicable provisions of the Financial Services and Markets Act 2002,
         as amended, with respect to anything done by it in relation to the
         Offered Securities in, from or otherwise involving the United Kingdom.

         5.  Certain Agreements of the Company.  The Company agrees with the
         several Purchasers that:

                  (a)  The Company will advise CSFBC promptly of any proposal to
         amend or supplement the Offering Document and will not effect such
         amendment or supplementation without CSFBC's consent, which consent
         shall not be unreasonably withheld. 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

                                       9

<PAGE>

         will notify CSFBC of such event and promptly will prepare, at its own
         expense, an amendment or supplement which will correct such statement
         or omission. Neither CSFBC'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 CSFBC 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 CSFBC reasonably requests. 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 CSFBC
         (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, a reasonable number of 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 arrange for the qualification of the
         Offered Securities for sale and the determination of their eligibility
         for investment under the laws of such jurisdictions in the United
         States and Canada as CSFBC 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)  To the extent that the Company's periodic reports under
         the Exchange Act are not readily available in the Commission's EDGAR
         system (or any successor thereto), or the Company no longer files
         periodic reports under Section 13 or 15(d) of the Exchange Act, during
         the period of five years hereafter, the Company will furnish to CSFBC
         and, upon request, to each of the other Purchasers, as soon as
         practicable after the end of each fiscal year, a copy of its annual
         report to shareholders for such year; and the Company will furnish to
         CSFBC and, upon request, to each of the other Purchasers (i) as soon as
         available, a copy of each report and any definitive proxy statement of
         the Company filed with the Commission under the Exchange Act or mailed
         to shareholders, and (ii) from time to time, such other information
         concerning the Company as CSFBC may reasonably request.

                  (e)  During the period of two years after the Closing Date or,
         if earlier until such time as the Offered Securities are no longer
         restricted securities (as defined in Rule 144 under the Securities
         Act), the Company will, upon request, furnish to CSFBC, each of the
         other Purchasers and any holder of Offered Securities a copy of the
         restrictions on transfer applicable to the Offered Securities.

                  (f)  During the period of two years after the Closing Date or,
         if earlier until such time as the Offered Securities are no longer
         restricted securities (as defined in Rule 144 under the Securities
         Act), 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.

                  (g)  During the period of two years after the Closing Date or,
         if earlier until such time as the Offered Securities are no longer
         restricted securities (as defined in Rule 144 under the Securities
         Act), 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.

                  (h)  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 counsel; (ii) all expenses in connection with
         the execution, issuance,

                                       10

         Securities and, as applicable, the Exchange Securities (as defined in
         the Registration Rights Agreement), the preparation and printing by the
         Company's advisors and printers 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 listing the Offered Securities and qualifying the Offered Securities
         for trading in The Portal(SM) Market ("PORTAL") and any expenses
         incidental thereto; (iv) the cost of any advertising approved in
         writing by the Company in connection with the issuance of the Offered
         Securities; (v) any reasonable 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 in the United States and Canada as CSFBC
         designates and the printing of memoranda relating thereto; (vi) for any
         fees charged by investment rating agencies for the rating of the
         Securities or the Exchange Securities; and (vii) for expenses incurred
         in distributing the Preliminary Offering Circulars and the Offering
         Document (including any amendments and supplements thereto) to the
         Purchasers. The Company will also pay or reimburse the Purchasers (to
         the extent incurred by them) for all travel expenses of the Purchasers
         and the Company's officers and employees and any other reasonable
         expenses of the Purchasers and the Company in connection with attending
         or hosting meetings between the Company and with prospective purchasers
         of the Offered Securities from the Purchasers.

                  (i) In connection with the offering, until CSFBC shall have
         notified the Company and the other Purchasers of the completion of the
         resale of the Offered Securities (which it agrees to do promptly after
         such completion), 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.

                  (j) Other than notes evidencing indebtedness under the Credit
         Agreement or any of the Company's or its subsidiaries' securitization
         facilities, for a period of 180 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 United States dollar-denominated debt
         securities issued or guaranteed by the Company and having a maturity of
         more than one year from the date of issue except issuances of Exchange
         Securities pursuant to the Registration Rights Agreement. 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. For the purposes of
         this section, all references to "subsidiaries" shall be deemed to
         include all entities that are subsidiaries of the Company. 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 letters, dated the date
         of this Agreement, from each of Deloitte & Touche LLP and Ernst & Young
         LLP in agreed form 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") in
         form and substance previously agreed to by the Purchasers and their
         counsel.

<PAGE>

                  (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 CSFBC,
         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; (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) or any announcement that the Company has been placed on
         negative outlook; (iii) any change in U.S. or international financial,
         political or economic conditions or currency exchange rates or exchange
         controls as would, in the interest 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 CSFBC, 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.

                  (c) The Purchasers shall have received an opinion, dated such
         Closing Date, of Dechert, counsel for the Company, that:

                          (i)  The Company has been duly incorporated and is
                  validly existing as a corporation in good standing under the
                  laws of the State of Delaware, with corporate power and
                  authority to own its properties and conduct its business as
                  described in the Offering Document; and, based solely on such
                  counsel's review of certificates of qualification to do
                  business as a foreign corporation, the Company is duly
                  qualified to do business as a foreign corporation in good
                  standing in all other jurisdictions set forth in an exhibit to
                  the opinion (which exhibit shall identify, based solely on a
                  certificate of an officer of the Company, each jurisdiction in
                  which the Company owns or leases material properties or
                  conducts material business) except to the extent that the
                  failure to be so qualified or be in good standing would not
                  have a Material Adverse Effect.

                          (ii) Each Guarantor incorporated or formed in the
                  State of California, the State of Connecticut, the State of
                  Delaware, the State of New Jersey, the State of New York or
                  the Commonwealth of Pennsylvania (the "Relevant Guarantors")
                  has been, to the extent a corporation, duly incorporated, and,
                  to the extent a limited liability company or limited
                  partnership, duly formed and is validly existing and in good
                  standing under the laws of the jurisdiction of its
                  incorporation or formation and has the corporate, limited
                  liability company or limited partnership power and authority
                  to own its property and to conduct its business as described
                  in the Offering Document; and each Relevant Guarantor, based
                  solely on such counsel's review of certificates of
                  qualification to do business as a foreign corporation, is duly
                  qualified to transact business and is in good standing in each
                  jurisdiction set forth in an exhibit to the opinion (which
                  exhibit shall identify, based solely on a certificate of an
                  officer of the Company, each jurisdiction in which the Company
                  or

                                       12

<PAGE>

         any Relevant Guarantor owns or leases material properties or conducts
         material business) except to the extent that the failure to be so
         qualified or be in good standing would not have a Material Adverse
         Effect.

              (iii)  The Indenture has been duly authorized, executed and
         delivered by the Company and the Relevant Guarantors; the Offered
         Securities have been duly authorized, executed and delivered by the
         Company; the Subsidiary Guarantees have been duly authorized, executed
         and delivered by the Relevant Guarantors; and the Indenture, the
         Offered Securities and such Subsidiary Guarantees, when duly
         authenticated by the Trustee in accordance with the terms of the
         Indenture and delivered and paid for in accordance with the terms of
         this Agreement, constitute valid and legally binding obligations of the
         Company and the Relevant Guarantors, respectively, 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.

              (iv)   Assuming that the Indenture and the Subsidiary Guarantees
         have been duly authorized, executed and delivered by each Guarantor
         other than the Relevant Guarantors, the Indenture and the Offered
         Securities, when duly authenticated by the Trustee in accordance with
         the terms of the Indenture and delivered and paid for in accordance
         with the terms of this Agreement, constitute valid and legally binding
         obligations of each Guarantor other than the Relevant Guarantors,
         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.

              (v)    The Company is not and, after giving effect to the offering
         and sale of the Offered Securities and the application of the proceeds
         thereof as described in the Offering Circular, will not be an
         "investment company" as defined in the Investment Company Act.

              (vi)   No consent, approval, authorization or order of, or filing
         with, any governmental agency or body or any court is required for the
         offer and sale of the Securities or the transactions contemplated by
         the Registration Rights Agreement (subject to the assumptions set forth
         in paragraph (xi) as it relates to the Securities Act and the Trust
         Indenture Act), except such as may be required under state securities
         or blue sky laws or regulations and, with respect to the Exchange Offer
         Registration Statement, the Registration Rights Agreement and the
         transactions contemplated thereunder, as may be required under the
         Securities Act or the Exchange Act or the rules and regulations of the
         Commission promulgated thereunder or the bylaws of the National
         Association of Securities Dealers, Inc.

              (vii)  Except as set forth in, or incorporated by reference in,
         the Offering Document, there are, to such counsel's knowledge, no
         pending or threatened actions, suits or proceedings against or
         affecting the Company, any of its subsidiaries or any of their
         respective properties that, is reasonably likely to be determined
         adversely to the Company or any of its subsidiaries, and if so
         adversely determined would individually or in the aggregate have 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.

              (viii) The execution, delivery and performance by the Company of
         the Indenture, this Agreement and the Registration Rights Agreement, as
         applicable, and the issuance and sale by the Company 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

                                       13

<PAGE>

         of, or constitute a default under, (i) any statute, rule, regulation
         applicable to the Company or, to such counsel's knowledge, order of
         any governmental agency or body or any court having jurisdiction over
         the Company or any subsidiary of the Company or any of their
         properties (other than a breach or violation that is not likely to
         cause a Material Adverse Effect), (ii) any agreement or instrument,
         set forth in an exhibit to the opinion (which exhibit shall identify,
         based solely on a certificate of an officer of the Company, all
         material agreements or instruments of the Company) (other than a
         breach or violation that is not likely to cause a Material Adverse
         Effect) 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.

              (ix)   Such counsel has no reason to believe that the descriptions
         in the Offering Circular under the caption "Description of the Notes,"
         insofar as they purport to constitute a summary of the terms of the
         Offered Securities, and under the captions "Certain United States
         Federal Income Tax Consequences" and "Transfer Restrictions," insofar
         as they purport to describe the provisions of the law and documents
         referred to therein, do not summarize in all material respects the
         matters referred to therein.

              (x)    This Agreement has been duly authorized, executed and
         delivered by the Company and the Guarantors.

              (xi)   Assuming (A) the accuracy of the representations and
         warranties of the Company set forth in Items (w), (y), (aa), (bb),
         (cc), (dd), (ee) and (ff) of Section 2 of this Agreement, (B) the due
         performance by the Company of the agreements set forth in Section 5 of
         this Agreement, (C) the accuracy of the representations and warranties
         made by the Purchasers of the agreement set forth in Section 4 of this
         Agreement, (D) compliance by the Purchasers with the offering and
         transfer procedures and restrictions described elsewhere in this
         Agreement and the Offering Document and (E) the accuracy of the
         representations and warranties made in accordance with this Agreement
         and the Offering Document by purchasers to whom the Purchasers
         initially resell the Offered Securities, it is not necessary in
         connection with (i) the offer, sale and delivery of the Offered
         Securities by the Company to the several Purchasers pursuant to this
         Agreement or (ii) the resales of the Offered Securities by the several
         Purchasers in the manner contemplated by this Agreement, to register
         the Offered Securities under the Securities Act (it being understood
         that no opinion shall be expressed as to any resale subsequent to the
         initial resale of the Offered Securities); and it is not necessary in
         connection with the offer, sale, or delivery of the Offered Securities
         to the initial Purchasers in the manner contemplated by the Purchase
         Agreement or in connection with the Exempt Resales to qualify the
         Indenture under the Trust Indenture Act.

              (xii)  The Indenture conforms in all material respects to the
         requirements of the Trust Indenture Act of 1939, as amended (the "TIA"
         or "Trust Indenture Act"), and the rules and regulations of the
         Commission applicable to an indenture which is qualified thereunder.

              (xiii) The Exchange Securities and the Exchange Security
         Guarantees have been duly authorized by the Company and each of the
         Relevant Guarantors, as applicable.

              (xiv)  The Registration Rights Agreement has been duly authorized,
         executed and delivered by the Company and each of the Relevant
         Guarantors, and (assuming due authorization, execution and delivery by
         the parties thereto other than the Company and the Relevant Guarantors)
         is a valid and binding agreement of the Company and each of the
         Guarantors, enforceable against the Company and each Guarantor in
         accordance with its terms, subject to bankruptcy, insolvency,
         fraudulent transfer, reorganization, moratorium

                                       14

<PAGE>

         and similar laws of general applicability relating to or affecting
         creditors' rights and to general equity principles.

              (xv) To such counsel's knowledge, there are no contracts,
         agreements or understandings between the Company or any Guarantor and
         any person granting such person the right to require the Company or
         such Guarantor to file a registration statement under the Securities
         Act with respect to any securities of the Company or such Guarantor and
         to require the Company or such Guarantor to include such securities
         with the Securities and Subsidiary Guarantees registered pursuant to
         any Registration Statement.

         In rendering such opinion, such counsel may rely as to matters of fact,
to the extent they deem proper, on certificates of responsible officers of the
Company and public officials. Such opinion may be limited to the General
Corporation Law and the Limited Liability Company Act of the State of Delaware,
the New Jersey Business Corporation Act, the laws of the State of California,
the laws of the State of Connecticut, the laws of the State of New York, the
laws of the Commonwealth of Pennsylvania and the federal laws of the United
States.

         Such counsel shall also state, in a separate letter, that, in the
course of preparation by the Company of the Offering Circular, such counsel has
participated in conferences with directors, officers and other representatives
of the Company, representatives of the independent public accountants for the
Company, representatives of the Purchasers and representatives of counsel for
the Purchasers, at which conferences the contents of the Offering Circular and
related matters were discussed and, although such counsel has not independently
verified and is not passing upon and assumes no responsibility for the accuracy,
completeness or fairness of the statements contained in the Offering Circular
(except as expressly provided above), and noting that they have relied as to
materiality to a large extent upon the statements of directors, officers and
other representatives of the Company, on the basis of the information that was
developed in the course of the performance of the services referred to above,
considered in light of such counsel's understanding of the applicable law, no
facts have come to such counsel's attention which has caused such counsel to
believe that as of the date of the Offering Document and at the Closing Date,
the Offering Circular contained an untrue statement of a material fact or
omitted to state any material fact necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading (it being understood that such counsel need express no view with
respect to the financial statements and the notes related thereto or any other
financial data, statistical data derived from financial data and accounting data
included or incorporated by reference in the Offering Circular).

         (d) The Purchasers shall have received an opinion, dated the Closing
Date, of Dechert, counsel to the Company, for each Guarantor not incorporated or
formed under the laws of California, Connecticut, Delaware, New Jersey, New York
or Pennsylvania, that:

              (i)   each of the relevant Guarantors has been duly incorporated
         and is validly existing as a corporation in good standing under the
         laws of the jurisdiction in which it is chartered or organized, with
         corporate power and authority to own its properties and conduct its
         business as described in the Offering Document;

              (ii)  each of the Subsidiary Guarantees has been duly authorized,
         executed and delivered and each of the Exchange Securities Guarantees
         has been duly authorized, in each case by each of the relevant
         Guarantors that is a party hereto or thereto; and

              (iii) the Indenture and the Registration Rights Agreement has been
         duly authorized, executed and delivered by each of the relevant
         Guarantors.

                                       15

<PAGE>

                  In rendering such opinion, such counsel may rely (A) as to
        matters involving the application of laws of any jurisdiction other than
        the jurisdiction in which the relevant Guarantors are chartered or
        organized or the United States, to the extent they deem proper and
        specified in such opinion, upon the opinion of other counsel who are
        satisfactory to counsel for the Purchasers, and (B) as to matters of
        fact, to the extent they deem proper, on certificates of responsible
        officers of the relevant Guarantors and public officials. Furthermore,
        such counsel may assume, for the purpose of rendering such opinion, that
        the laws of the jurisdiction in which the relevant Guarantors are
        chartered or organized are identical to the laws of Delaware.

                  (e) The Purchasers shall have received from Latham & Watkins,
         counsel for the Purchasers, such opinion or opinions, dated such
         Closing Date, with respect to the incorporation of the Company, the
         validity of the Offered Securities, 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 CSFBC may require, and the Company shall have furnished to such
         counsel such documents as they reasonably 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 Closing
         Date, and that, subsequent to the date of the most recent financial
         statements included or incorporated by reference in the Offering
         Document there has been no material adverse change, nor any development
         or event involving a prospective material adverse change, in the
         condition (financial or other), 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 letters, dated the
         Closing Date, from each of Deloitte & Touche LLP and Ernst & Young LLP
         which meet 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 five days prior to the Closing Date for the purposes of
         this subsection.

                  (h) The Purchasers shall have received a certificate, dated
         the Closing Date, of the Senior Vice President and Chief Financial
         Officer of the Company stating that:

                      (i)  as of September 30, 2002, the amount that would have
         been available to the Company for Restricted Payments pursuant to the
         second clause (3) of the first paragraph under the section "Description
         of Notes -- Certain Covenants -- Restricted Payments" in the Offering
         Document was $294.2 million; and

                      (ii) as of September 30, 2002, those subsidiaries of the
         Company designated as "Designated Non-Guarantors" in an officers'
         certificate delivered to the Purchasers and the Trustee pursuant to the
         definition of "Designated Non-Guarantors" in the Indenture,
         individually and in the aggregate, represent less than 3.0% of the
         Company's consolidated total assets, consolidated stockholders' equity,
         consolidated revenues, consolidated income from continuing operations
         before income taxes and consolidated cash flows from operating
         activities.

                  Documents described as being "in the agreed form" are
       documents which are in the forms which have been initialled for the
       purpose of identification by Latham & Watkins, copies of which are held
       by the Company and CSFBC, with such changes as CSFBC may approve.

                                       16

<PAGE>

                  The Company will furnish the Purchasers with such conformed
       copies of such opinions, certificates, letters and documents as the
       Purchasers reasonably request. CSFBC 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 and the Guarantors will, jointly and
         severally, 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 the 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 (i) 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 CSFBC 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 or (ii) results from the fact
         that such Purchaser failed to deliver an Offering Circular, as then
         amended or supplemented, (so long as the Offering Circular and any
         amendment or supplement thereto was provided by the Company to the
         Purchasers in the requisite quantity and on a timely basis to permit
         proper delivery on or prior to the Closing Date) to the person
         asserting any losses, claims, damages, liabilities or judgments caused
         by any untrue statement or omission or alleged untrue statement or
         omission of a material fact contained in any Preliminary Offering
         Circular, and such untrue statement or alleged untrue statement or
         omission was cured in the Offering Circular.

                  (b) Each Purchaser will severally and not jointly indemnify
         and hold harmless the Company, each Guarantor, their directors and
         officers and each person, if any, who controls the Company or such
         Guarantor within the meaning of Section 15 of the Securities Act,
         against any losses, claims, damages or liabilities to which the Company
         or such Guarantor 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
         CSFBC 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
         (i) the following information in the Offering Document furnished on
         behalf of each Purchaser: under the caption "Plan of Distribution"
         paragraphs three, ten and twelve and the third sentence of paragraph
         nine; provided, however, that the Purchasers shall not be liable for
         any

                                       17

<PAGE>

         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 written 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
         omission so to notify the indemnifying party in writing will not
         relieve it from any liability which it may have to any 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 elect by written notice, jointly with any other indemnifying
         party similarly notified, to assume the defense thereof, with counsel
         reasonably satisfactory to such indemnified party. 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
         prior to assumption of defenses. 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, culpability 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 discounts, fees and commissions received by
         such Purchaser 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 and the Guarantors under
         this Section shall be in addition to any liability which the Company
         and the Guarantors may otherwise have and shall

                                       18

<PAGE>

         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 or the
         Guarantors 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 Offered Securities hereunder and the aggregate
principal amount of Offered Securities that such defaulting Purchaser or
Purchasers agreed but failed to purchase does not exceed 10% of the total
principal amount of Offered Securities, CSFBC 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 such
Closing Date, the non-defaulting Purchasers shall be obligated severally, in
proportion to their respective commitments hereunder, to purchase the Offered
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 Offered Securities with respect to which such default or
defaults occur exceeds 10% of the total principal amount of Offered Securities
and arrangements satisfactory to CSFBC 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 Corporation, Eleven Madison
Avenue, New York, N.Y. 10010-3629, Attention: Investment Banking Department -
Transactions Advisory Group, if sent to the Company or the Guarantors, will be
mailed, delivered or telegraphed and confirmed to it at AmerisourceBergen
Corporation, 1300 Morris Drive, Suite 100, Chesterbrook, PA 19087-5594,
Attention: General Counsel; 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 thereto.

         12. Representation of Purchasers.  CSFBC, Banc of America Securities
LLC and J.P. Morgan Securities Inc. will act for the several Purchasers in
connection with this purchase, and any action under this

                                       19

<PAGE>

Agreement taken by CSFBC, Banc of America Securities LLC and J.P. Morgan
Securities Inc. jointly or by CSFBC 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 and the Guarantors hereby submit 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 us one of the counterparts hereof,
whereupon it will become a binding agreement among the Company, the Guarantors
and the several Purchasers in accordance with its terms.
