ITEM 5.  OTHER EVENTS

   On August 24, 1997, Bergen Brunswig Corporation ("Bergen") and Cardinal
Health, Inc. ("Cardinal") announced that they have entered into an Agreement
and Plan of Merger, dated as of August 23, 1997 (the "Merger Agreement"),
pursuant to which Bruin Merger Corp., a newly formed wholly owned subsidiary of
Cardinal, will be merged with and into Bergen and Bergen will become a wholly
owned subsidiary of Cardinal (the "Merger").  Under the terms of the Merger
Agreement, shareholders of Bergen will receive 0.7750 of a Cardinal Common
Share for each share of Bergen Common Stock they hold upon consummation of the
Merger.  The Merger is intended to be tax-free and to qualify as a pooling of
interests for financial reporting purposes.  Consummation of the transaction is
subject to the satisfaction of certain conditions, including approvals by the
shareholders of Bergen and Cardinal and receipt of certain regulatory
approvals.

     The Merger Agreement also provides that in the event the Merger is
terminated pursuant to certain of the circumstances specified under Article VII
thereof, either Bergen or Cardinal, depending upon the circumstances giving rise
to the termination, may be obligated to pay to the other a termination fee or as
liquidated damages, either $50 million or $75 million. In addition to such
payment, in certain circumstances set forth in such Article, one party may
become obligated to reimburse the other party up to $12 million for costs and
expenses incurred in connection with the transaction.

   The Merger Agreement is filed as Exhibit 99.1 hereto and is incorporated
herein by reference.  The foregoing description of the Merger Agreement is
qualified in its entirety by reference to such Exhibit.

   In connection with the execution of the Merger Agreement, Bergen and
Cardinal entered into a Stock Option Agreement, dated August 23, 1997 (the
"Stock Option Agreement"), pursuant to which Bergen granted Cardinal an option,
exercisable under certain circumstances specified in such agreement, to
purchase up to 10,028,163 shares of Bergen Common Stock (approximately 19.9% of
the outstanding shares of Bergen Brunswig Stock, without giving effect to the
exercise of the option), at a purchase price of $48.29 per share.  The Stock
Option Agreement is filed as Exhibit 99.2 hereto and is incorporated herein by
reference.  The foregoing description of the Stock Option Agreement is
qualified in its entirety by reference to such Exhibit.

   In connection with the execution of the Merger Agreement, Mr. Robert E.
Martini, Chairman of Bergen, entered into a Support/Voting Agreement, dated
August 23, 1997 (the "Support/Voting Agreement"), with Cardinal, pursuant to
which Mr. Martini agreed to take certain actions in connection with the
proposed Merger, including voting the shares of Bergen Common Stock
beneficially owned by him in favor of the Merger at any meeting of shareholders
held to consider the Merger.  Mr. Martini beneficially owns approximately 5.5%
of the outstanding shares of Bergen Common Stock.  The Support/Voting Agreement
is filed as Exhibit

                           AGREEMENT AND PLAN OF MERGER


                   This Agreement and Plan of Merger (this "Agreement")
         is made and entered into as of the 23rd day of August, 1997, by
         and among Cardinal Health, Inc., an Ohio corporation
         ("Cardinal"), Bruin Merger Corp., a New Jersey corporation and
         a wholly owned subsidiary of Cardinal ("Subcorp"), and Bergen
         Brunswig Corporation, a New Jersey corporation ("Bergen").

                              PRELIMINARY STATEMENTS

                   A.  Cardinal desires to combine its pharmaceutical
         distribution business and other businesses with the
         pharmaceutical distribution business and other businesses
         operated by Bergen through the merger of Subcorp with and into
         Bergen, with Bergen as the surviving corporation (the
         "Merger"), pursuant to which each share of Bergen Common Stock
         (as defined in Section 4.4) outstanding at the Effective Time
         (as defined in Section 1.2) will be converted into the right to
         receive Cardinal Common Shares (as defined in Section 3.4) as
         more fully provided herein.

                   B.  The Board of Directors of Bergen has determined
         that the Merger is consistent with and in furtherance of the
         long-term business strategy of Bergen and Bergen desires to
         combine its pharmaceutical distribution business and other
         businesses with the healthcare service businesses operated by
         Cardinal and for the holders of shares of Bergen Common Stock
         ("Bergen Shareholders") to have a continuing equity interest in
         the combined Cardinal/Bergen businesses through the ownership
         of Cardinal Common Shares.

                   C.  The parties intend that the Merger constitute a
         tax-free "reorganization" within the meaning of Section
         368(a)(1)(A) of the Internal Revenue Code of 1986, as amended
         (the "Code"), by reason of Section 368(a)(2)(E) thereof.

                   D.  The parties intend that the Merger be accounted
         for as a pooling-of-interests for financial reporting purposes.

                   E.  The respective Boards of Directors of Cardinal,
         Subcorp and Bergen have determined the Merger in the manner
         contemplated herein to be desirable and in the best interests
         of their respective shareholders and, by resolutions duly
         adopted, have approved and adopted this Agreement.


                                    AGREEMENT

                   Now, therefore, in consideration of these premises
         and the mutual and dependent promises hereinafter set forth,
         the parties hereto agree as follows:

                                    ARTICLE I.

                                    THE MERGER

                   1.1  The Merger.  Upon the terms and subject to the
         conditions hereof, and in accordance with the provisions of the
         New Jersey Business Corporation Act (the "NJBCA"), Subcorp
         shall be merged with and into Bergen at the Effective Time.  As
         a result of the Merger, the separate corporate existence of
         Subcorp shall cease and Bergen shall continue its existence
         under the laws of the State of New Jersey.  Bergen, in its
         capacity as the corporation surviving the Merger, is
         hereinafter sometimes referred to as the "Surviving
         Corporation."

                   1.2  Effective Time.  As promptly as possible on the
         Closing Date (as defined below), the parties shall cause the
         Merger to be consummated by filing with the Secretary of State
         of the State of New Jersey (the "New Jersey Secretary of
         State") a certificate of merger (the "Certificate of Merger")
         in such form as is required by and executed in accordance with
         Section 14A:10-4.1 of the NJBCA.  The Merger shall become
         effective (the "Effective Time") when the Certificate of Merger
         has been filed with the New Jersey Secretary of State or at
         such later time as shall be agreed upon by Cardinal and Bergen
         and specified in the Certificate of Merger.  Prior to the
         filing referred to in this Section 1.2, a closing (the
         "Closing") shall be held at the offices of Cardinal, 5555
         Glendon Court, Dublin, Ohio 43016, or such other place as the
         parties may agree as soon as practicable (but in any event
         within ten business days) following the date upon which all
         conditions set forth in Article VI hereof have been satisfied
         or waived, or at such other date as Cardinal and Bergen may
         agree; provided, that the conditions set forth in Article VI
         have been satisfied or waived at or prior to such date.  The
         date on which the Closing takes place is referred to herein as
         the "Closing Date."  For all tax purposes, the Closing shall be
         effective at the end of the day on the Closing Date.

                   1.3  Effects of the Merger.  From and after the
         Effective Time, the Merger shall have the effects set forth in
         Section 14A:10-6 of the NJBCA.

                   1.4  Certificate of Incorporation and Bylaws.  At the
         Effective Time (i) the Certificate of Incorporation of the
         Surviving Corporation as in effect immediately prior to the
         Effective Time shall be amended as of the Effective Time so as
         to contain the provisions, and only the provisions, contained
         immediately prior thereto in the Amended and Restated
         Certificate of Incorporation of Subcorp, except for Article I
         thereof which shall continue to read "The name of the
         corporation is 'BERGEN BRUNSWIG CORPORATION'", and (ii) the
         Bylaws of Subcorp in effect immediately prior to the Effective
         Time shall be the Bylaws of the Surviving Corporation; in each
         case until amended in accordance with applicable law.  Cardinal
         agrees not to amend the Certificate of Incorporation of the
         Surviving Corporation for a period of at least one year from
         the Effective Time.

                   1.5  Directors and Officers of the Surviving
         Corporation.  From and after the Effective Time, the officers
         of Bergen shall be the officers of the Surviving Corporation


                                     -2-

<PAGE>   7








         and the directors of Subcorp shall be the directors of the
         Surviving Corporation, in each case until their respective
         successors are duly elected and qualified.  On or prior to the
         Closing Date, Bergen shall deliver to Cardinal a written
         acknowledgment reasonably satisfactory to Cardinal from each
         director of Bergen  that they will not be directors of Bergen
         or the Surviving Corporation effective as of the Effective
         Time. 

                   1.6  Additional Actions.  If, at any time after the
         Effective Time, the Surviving Corporation shall consider or be
         advised that any further deeds, assignments or assurances in
         law or any other acts are necessary or desirable to (a) vest,
         perfect or confirm, of record or otherwise, in the Surviving
         Corporation its right, title or interest in, to or under any of
         the rights, properties or assets of Bergen, or (b) otherwise
         carry out the provisions of this Agreement, Bergen and its
         officers and directors shall be deemed to have granted to the
         Surviving Corporation an irrevocable power of attorney to
         execute and deliver all such deeds, assignments or assurances
         in law and to take all acts necessary, proper or desirable to
         vest, perfect or confirm title to and possession of such
         rights, properties or assets in the Surviving Corporation and
         otherwise to carry out the provisions of this Agreement, and
         the officers and directors of the Surviving Corporation are
         authorized in the name of Bergen or otherwise to take any and
         all such action.

                                   ARTICLE II.

                             CONVERSION OF SECURITIES

                   2.1  Conversion of Capital Stock.  At the Effective
         Time, by virtue of the Merger and without any action on the
         part of Cardinal, Subcorp or Bergen or their respective
         shareholders:

                   (a)  Each share of common stock, $0.01 par value, of
              Subcorp issued and outstanding immediately prior to the
              Effective Time shall be converted into one share of common
              stock, $0.01 par value, of the Surviving Corporation.
              Such newly issued shares shall thereafter constitute all
              of the issued and outstanding capital stock of the
              Surviving Corporation.

                   (b)  Subject to the other provisions of this Article
              II, each share of Bergen Common Stock issued and
              outstanding immediately prior to the Effective Time shall
              be converted into and represent a number of Cardinal
              Common Shares equal to the Exchange Ratio (as defined in
              Section 2.2(a)).

                   (c)  Each share of capital stock of Bergen held in
              the treasury of Bergen shall be cancelled and retired and
              no payment shall be made in respect thereof. 

                   2.2  Exchange Ratio; Fractional Shares; Adjustments.

                   (a)  The "Exchange Ratio" shall be equal to 0.775.
              No certificates for fractional Cardinal Common Shares
              shall be issued as a result of the conversion provided for
              in Section 2.1(b).

                   (b)  In lieu of any such fractional shares, the
              holder of a certificate previously evidencing Bergen
              Common Stock, upon presentation of such fractional
              interest represented by an appropriate certificate for
              Bergen Common Stock to the Exchange Agent pursuant to
              Section 2.3, shall be entitled to receive a cash payment
              therefor in an amount equal to the value (determined with
              reference to the closing price of Cardinal Common Shares
              as reported on the New York Stock Exchange ("NYSE")
              Composite Tape ("NYSE Composite Tape") on the last full
              trading day immediately prior to the Closing Date) of such
              fractional interest.  Such payment with respect to
              fractional shares is merely intended to provide a
              mechanical rounding off of, and is not a separately
              bargained for, consideration.  If more than one
              certificate representing shares of Bergen Common Stock
              shall be surrendered for the account of the same holder,
              the number of Cardinal Common Shares for which
              certificates have been surrendered shall be computed on
              the basis of the aggregate number of shares represented by
              the certificates so surrendered. 

                   (c)  In the event that prior to the Effective Time
              Cardinal shall declare a stock dividend or other
              distribution payable in Cardinal Common Shares or
              securities convertible into Cardinal Common Shares, or
              effect a stock split, reclassification, combination or
              other change with respect to Cardinal Common Shares, the
              Exchange Ratio set forth in this Section 2.2 shall be
              adjusted to reflect such dividend, distribution, stock
              split, reclassification, combination or other change.

                   2.3  Exchange of Certificates.

                   (a)  Exchange Agent.  Promptly following the
              Effective Time, Cardinal shall deposit with ChaseMellon
              Shareholder Services, Inc. or such other exchange agent as
              may be designated by Cardinal (the "Exchange Agent"), for
              the benefit of Bergen Shareholders, for exchange in
              accordance with this Section 2.3, certificates
              representing Cardinal Common Shares issuable pursuant to
              Section 2.1 in exchange for outstanding shares of Bergen
              Common Stock and shall from time-to-time deposit cash in
              an amount reasonably expected to be paid pursuant to
              Section 2.2 (such Cardinal Common Shares and cash,
              together with any dividends or distributions with respect
              thereto, being hereinafter referred to as the "Exchange
              Fund").

                   (b)  Exchange Procedures.  As soon as practicable
              after the Effective Time, Cardinal shall instruct the
              Exchange Agent to mail to each holder of record of a
              certificate or certificates (the "Certificates") which
              immediately prior to the Effective Time represented
              outstanding shares of Bergen Common Stock whose shares
              were converted into the right to receive Cardinal Common
              Shares pursuant to Section 2.1(b), (i) a letter of
              transmittal (the form and substance of which shall have
              been reasonably approved by Bergen prior to the Effective
              Time and which shall specify that delivery shall be
              effected, and risk of loss and title to the Certificates
              shall pass, only upon delivery of the Certificates to the
              Exchange Agent and shall be in such form and have such
              other customary provisions as Cardinal may reasonably
              specify) and (ii) instructions for effecting the surrender
              of the Certificates in exchange for certificates
              representing 


                                     -4-

              Cardinal Common Shares.  Upon surrender of a Certificate
              for cancellation to the Exchange Agent, together with a
              duly executed letter of transmittal, the holder of such
              Certificate shall be entitled to receive in exchange
              therefor (x) a certificate or certificates representing
              that whole number of Cardinal Common Shares which such
              holder has the right to receive pursuant to Section 2.1 in
              such denominations and registered in such names as such
              holder may request and (y) a check representing the amount
              of cash in lieu of fractional shares, if any, and unpaid
              dividends and distributions, if any, which such holder has
              the right to receive pursuant to the provisions of this
              Article II, after giving effect to any required
              withholding tax.  The shares represented by the
              Certificate so surrendered shall forthwith be cancelled.
              No interest will be paid or accrued on the cash in lieu of
              fractional shares, if any, and unpaid dividends and
              distributions, if any, payable to holders of shares of
              Bergen Common Stock.  In the event of a transfer of
              ownership of shares of Bergen Common Stock which is not
              registered on the transfer records of Bergen, a
              certificate representing the proper number of Cardinal
              Common Shares, together with a check for the cash to be
              paid in lieu of fractional shares, if any, and unpaid
              dividends and distributions, if any, may be issued to such
              transferee if the Certificate representing such shares of
              Bergen Common Stock held by such transferee is presented
              to the Exchange Agent, accompanied by all documents
              required to evidence and effect such transfer and to
              evidence that any applicable stock transfer taxes have
              been paid.  Until surrendered as contemplated by this
              Section 2.3, each Certificate shall be deemed at any time
              after the Effective Time to represent only the right to
              receive upon surrender a certificate representing Cardinal
              Common Shares and cash in lieu of fractional shares, if
              any, and unpaid dividends and distributions, if any, as
              provided in this Article II.

                   (c)  Distributions with Respect to Unexchanged
              Shares.  Notwithstanding any other provisions of this
              Agreement, no dividends or other distributions declared or
              made after the Effective Time with respect to Cardinal
              Common Shares having a record date after the  Effective
              Time shall be paid to the holder of any unsurrendered
              Certificate, and no cash payment in lieu of fractional
              shares shall be paid to any such holder, until the holder
              shall surrender such Certificate as provided in this
              Section 2.3.  Subject to the effect of Applicable Laws (as
              defined in Section 3.10), following surrender of any such
              Certificate, there shall be paid to the holder of the
              certificates representing whole Cardinal Common Shares
              issued in exchange therefor, without interest, (i) at the
              time of such surrender, the amount of dividends or other
              distributions with a record date after the Effective Time
              theretofore payable with respect to such whole Cardinal
              Common Shares and not paid, less the amount of any
              withholding taxes which may be required thereon, and (ii)
              at the appropriate payment date subsequent to surrender,
              the amount of dividends or other distributions with a
              record date after the Effective Time but prior to
              surrender and a payment date subsequent to surrender
              payable with respect to such whole Cardinal Common Shares,
              less the amount of any withholding taxes which may be
              required thereon.

                   (d)  No Further Ownership Rights in Bergen Common
              Stock.  All Cardinal Common Shares issued upon surrender
              of Certificates in accordance with the terms


                                     -5-

<PAGE>   10








              hereof (including any cash paid pursuant to this Article
              II) shall be deemed to have been issued in full
              satisfaction of all rights pertaining to such shares of
              Bergen Common Stock represented thereby, and there shall
              be no further registration of transfers on the stock
              transfer books of Bergen of shares of Bergen Common Stock
              outstanding immediately prior to the Effective Time.  If,
              after the Effective Time, Certificates are presented to
              the Surviving Corporation for any reason, they shall be
              cancelled and exchanged as provided in this Section 2.3.
              Certificates surrendered for exchange by any person
              constituting an "affiliate" of Bergen for purposes of Rule
              145(c) under the Securities Act of 1933, as amended (the
              "Securities Act"), shall not be exchanged until Cardinal
              has received written undertakings from such person in the
              form attached hereto as Exhibit A-1.

                   (e)  Termination of Exchange Fund.  Any portion of
              the Exchange Fund which remains undistributed to Bergen
              Shareholders six months after the date of the mailing
              required by Section 2.3(b) shall be delivered to Cardinal,
              upon demand therefor, and holders of Certificates
              previously representing shares of Bergen Common Stock who
              have not theretofore complied with this Section 2.3 shall
              thereafter look only to Cardinal for payment of any claim
              to Cardinal Common Shares, cash in lieu of fractional
              shares thereof, or dividends or distributions, if any, in
              respect thereof.

                   (f)  No Liability.  None of Cardinal, the Surviving
              Corporation or the Exchange Agent shall be liable to any
              person in respect of any shares of Bergen Common Stock (or
              dividends or distributions with respect thereto) or cash
              from the Exchange Fund delivered to a public official
              pursuant to any applicable abandoned property, escheat or
              similar law.  If any Certificates shall not have been
              surrendered prior to seven years after the Effective Time
              of the Merger (or immediately prior to such earlier date
              on which any cash, any cash in lieu of fractional shares
              or any dividends or distributions with respect to whole
              shares of Bergen Common Stock in respect of such
              Certificate would otherwise escheat to or become the
              property of any Governmental Authority (as defined in
              Section 3.5)), any such cash, dividends or distributions
              in respect of such Certificate shall, to the extent
              permitted by Applicable Laws, become the property of
              Cardinal, free and clear of all claims or interest of any
              person previously entitled thereto.

                   (g)  Investment of Exchange Fund.  The Exchange Agent
              shall invest any cash included in the Exchange Fund, as
              directed by Cardinal, on a daily basis.  Any interest and
              other income resulting from such investments shall be paid
              to Cardinal upon termination of the Exchange Fund pursuant
              to Section 2.3(e). 

                   2.4  Treatment of Stock Options.

                   (a)  Prior to the Effective Time, Cardinal and Bergen
              shall take all such actions as may be necessary to cause
              each unexpired and unexercised option under stock option
              plans of Bergen in effect on the date hereof which has
              been granted to current or former directors, officers or
              employees of Bergen by Bergen (or which has been granted
              by Bergen prior to the Effective Time pursuant to
              agreements in compliance with the terms of this Agreement)
              (each, a "Bergen Option") to be automatically converted at
              the


                                     -6-

              Effective Time into an option (a "Cardinal Exchange
              Option") to purchase that number of Cardinal Common Shares
              equal to the number of shares of Bergen Common Stock
              issuable immediately prior to the Effective Time upon
              exercise of the Bergen Option (without regard to actual
              restrictions on exercisability) multiplied by the Exchange
              Ratio, with an exercise price equal to the exercise price
              which existed under the corresponding Bergen Option
              divided by the Exchange Ratio, and with other terms and
              conditions that are the same as the terms and conditions
              of such Bergen Option immediately before the Effective
              Time; provided that with respect to any Bergen Option that
              is an "incentive stock option" within the meaning of
              Section 422 of the Code, the foregoing conversion shall be
              carried out in a manner satisfying the requirements of
              Section 424(a) of the Code.  In connection with the
              issuance of Cardinal Exchange Options, Cardinal shall (i)
              reserve for issuance the number of Cardinal Common Shares
              that will become subject to Cardinal Exchange Options
              pursuant to this Section 2.4 and (ii) from and after the
              Effective Time, upon exercise of Cardinal Exchange
              Options, make available for issuance all Cardinal Common
              Shares covered thereby, subject to the terms and
              conditions applicable thereto.

                   (b)  Bergen agrees to issue treasury shares of
              Bergen, to the extent available, upon the exercise of
              Bergen Options prior to the Effective Time.

                   (c)  Cardinal agrees to use its reasonable efforts to
              file with the Securities and Exchange Commission (the
              "Commission") within 15 business days after the Closing
              Date a registration statement on Form S 8 or other
              appropriate form under the Securities Act to register
              Cardinal Common Shares issuable upon exercise of the
              Cardinal Exchange Options and use its reasonable efforts
              to cause such registration statement to remain effective
              until the exercise or expiration of such options. 

                                   ARTICLE III.

              REPRESENTATIONS AND WARRANTIES OF CARDINAL AND SUBCORP

                   In order to induce Bergen to enter into this
         Agreement, Cardinal and Subcorp hereby represent and warrant to
         Bergen that the statements contained in this Article III are
         true, correct and complete. 

                   3.1  Organization and Standing.  Each of Cardinal and
         Subcorp is a corporation duly organized, validly existing and
         in good standing under the laws of its state of incorporation
         with full corporate power and authority to own, lease, use and
         operate its properties and to conduct its business as and where
         now owned, leased, used, operated and conducted.  Each of
         Cardinal and Subcorp is duly qualified to do business and in
         good standing in each jurisdiction in which the nature of the
         business conducted by it or the property it owns, leases or
         operates, makes such qualification necessary, except where the
         failure to be so qualified or in good standing in such
         jurisdiction would not reasonably be expected to have a
         Material Adverse Effect (as defined in Section 8.3) on
         Cardinal.  Cardinal is not in default in the performance,
         observance or fulfillment of any provision of its Articles of
         Incorporation, as amended and restated (the "Cardinal
         Articles"), or its Code of Regulations, as amended and restated
         (the "Cardinal Code of


                                     -7-

<PAGE>   12








         Regulations"), and Subcorp is not in default in the
         performance, observance or fulfillment of any provisions of its
         Amended and Restated Certificate of Incorporation or Bylaws.
         Cardinal has heretofore furnished to Bergen a complete and
         correct copy of the Cardinal Articles and Cardinal Code of
         Regulations.

                   3.2  Subsidiaries.  Except as set forth in Section
         3.2 to the disclosure schedule delivered by Cardinal to Bergen
         and dated the date hereof (the "Cardinal Disclosure Schedule"),
         Cardinal owns directly or indirectly each of the outstanding
         shares of capital stock (or other ownership interests having by
         their terms ordinary voting power to elect a majority of
         directors or others performing similar functions with respect
         to such subsidiary) of each of Cardinal's subsidiaries.

                   3.3  Corporate Power and Authority.  Each of Cardinal
         and Subcorp has all requisite corporate power and authority to
         enter into and deliver this Agreement, subject to approval of
         (i) amendments to the Cardinal Articles to change Cardinal's 
         name as provided for in Section 5.2(i) and to increase the 
         number of authorized Cardinal Common Shares, and (ii) the 
         issuance of Cardinal Common Shares issuable in the Merger and 
         the transactions contemplated hereby by the Cardinal Shareholders
         (such proposals to amend the Cardinal Articles and to authorize
         the issuance of Cardinal Common Shares collectively the
         "Cardinal Shareholder Proposals"), to perform its obligations
         hereunder and to consummate the transactions contemplated by
         this Agreement.  The execution and delivery of this Agreement
         and the consummation of the transactions contemplated hereby
         have been duly authorized by all necessary corporate action on
         the part of each of Cardinal and Subcorp, subject to approval
         by the Cardinal Shareholders of the Cardinal Shareholder
         Proposals.  This Agreement has been duly executed and delivered
         by each of Cardinal and Subcorp, and constitutes the legal,
         valid and binding obligation of each of Subcorp and Cardinal
         enforceable against each of them in accordance with its terms.

                   3.4  Capitalization of Cardinal and Subcorp.

                   (a)  As of August 7, 1997, Cardinal's authorized
         capital stock consisted solely of (a) 150,000,000 common
         shares, without par value ("Cardinal Common Shares"), of which
         (i) 109,097,646 shares were issued and outstanding, (ii)
         240,709 shares were issued and held in treasury (which does not
         include the shares reserved for issuance as set forth in clause
         (a)(iii) below) and (iii) 6,000,434 shares were reserved for
         issuance upon the exercise or conversion of options, warrants
         or convertible securities granted or issuable by Cardinal, (b)
         5,000,000 Class B common shares, without par value, none of
         which was issued and outstanding or reserved for issuance, and
         (c) 500,000 Non-Voting Preferred Shares, without par value,
         none of which was issued and outstanding or reserved for
         issuance.  Each outstanding share of Cardinal capital stock is,
         and all Cardinal Common Shares to be issued in connection with
         the Merger will be, duly authorized and validly issued, fully
         paid and nonassessable, and each outstanding share of Cardinal
         capital stock has not been, and all Cardinal Common Shares to
         be issued in connection with the Merger will not be, issued in
         violation of any preemptive or similar rights.  As of the date
         hereof, other than as set forth in the first sentence hereof or
         in


                                     -8-

<PAGE>   13








         Section 3.4 to the Cardinal Disclosure Schedule, there are no
         outstanding subscriptions, options, warrants, puts, calls,
         agreements, understandings, claims or other commitments or
         rights of any type relating to the issuance, sale, repurchase,
         transfer or registration by Cardinal of any equity securities
         of Cardinal, nor are there outstanding any securities which are
         convertible into or exchangeable for any shares of capital
         stock of Cardinal and neither Cardinal nor any Cardinal
         subsidiary has any obligation of any kind to issue any
         additional securities or to pay for or repurchase any
         securities of Cardinal, its subsidiaries or its or their
         predecessors.  The Cardinal Common Shares (including those
         shares to be issued in the Merger) are registered under the
         Securities Exchange Act of 1934, as amended (together with the
         rules and regulations thereunder, the "Exchange Act").  Except
         as set forth in Section 3.4 to the Cardinal Disclosure
         Schedule, Cardinal has no agreement, arrangement or
         understanding to register any securities of Cardinal or any of
         its subsidiaries under the Securities Act or under any state
         securities law and has not granted registration rights to any
         person or entity (other than agreements, arrangements or
         understandings with respect to registration rights that are no
         longer in effect as of the date of this Agreement); copies of
         all such agreements have previously been provided to Bergen.

                   (b)  Subcorp's authorized capital stock consists
         solely of 1,000 shares of Common Stock, par value $.01 per
         share ("Subcorp Common Stock"), of which, as of the date
         hereof, 100 were issued and outstanding and none were reserved
         for issuance.  As of the date hereof, all of the outstanding
         shares of Subcorp Common Stock are owned free and clear of any
         liens, claims or encumbrances by Cardinal.

                   3.5  Conflicts; Consents and Approval.  Neither the
         execution and delivery of this Agreement by Cardinal or Subcorp
         nor the consummation of the transactions contemplated hereby
         will:

                   (a)  conflict with, or result in a breach of any
              provision of the Cardinal Articles or Cardinal Code of
              Regulations or the Amended and Restated Certificate of
              Incorporation or Bylaws of Subcorp, subject to approval by
              the Cardinal Shareholders of the Cardinal Shareholder
              Proposals;

                   (b)  violate, or conflict with, or result in a breach
              of any provision of, or constitute a default (or an event
              which, with the giving of notice, the passage of time or
              otherwise, would constitute a default) under, or entitle
              any party (with the giving of notice, the passage of time
              or otherwise) to terminate, accelerate, modify or call a
              default under, or result in the creation of any lien,
              security interest, charge or encumbrance upon any of the
              properties or assets of Cardinal or any of its
              subsidiaries under, any of the terms, conditions or
              provisions of any note, bond, mortgage, indenture, deed of
              trust, license, contract, undertaking, agreement, lease or
              other instrument or obligation to which Cardinal or any of
              its subsidiaries is a party;


                                     -9-

<PAGE>   14








                   (c)  violate any order, writ, injunction, decree,
              statute, rule or regulation applicable to Cardinal or any
              of its subsidiaries or any of their respective properties
              or assets; or

                   (d)  require any action or consent or approval of, or
              review by, or registration or filing by Cardinal or any of
              its affiliates with, any third party or any local,
              domestic, foreign or multi-national court, arbitral
              tribunal, administrative agency or commission or other
              governmental or regulatory body, agency, instrumentality
              or authority (a "Governmental Authority"), other than (i)
              approval by the Cardinal Shareholders of the Cardinal
              Shareholder Proposals, (ii) authorization for inclusion of
              the Cardinal Common Shares to be issued in the Merger and
              the transactions contemplated hereby on the NYSE, subject
              to official notice of issuance, (iii) actions required by
              the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
              as amended, and the rules and regulations promulgated
              thereunder (the "HSR Act"), (iv) registrations or other
              actions required under federal and state securities laws
              as are contemplated by this Agreement, or (v) consents or
              approvals of any Governmental Authority set forth in
              Section 3.5 to the Cardinal Disclosure Schedule;

         except in the case of (b), (c) and (d) for any of the foregoing
         that would not, individually or in the aggregate, reasonably be
         expected to have a Material Adverse Effect on Cardinal or a
         material adverse effect on the ability of the parties to
         consummate the transactions contemplated hereby.

                   3.6  Brokerage and Finder's Fees.  Except as set
         forth in Section 3.6 of the Cardinal Disclosure Schedule,
         neither Cardinal nor any shareholder, director, officer or
         employee thereof has incurred or will incur on behalf of
         Cardinal any brokerage, finder's or similar fee in connection
         with the transactions contemplated by this Agreement.

                   3.7  Accounting Matters; Reorganization.  Neither
         Cardinal nor any of its affiliates has taken or agreed to take
         any action that (without giving effect to any actions taken or
         agreed to be taken by Bergen or any of its affiliates) would
         (a) prevent Cardinal from accounting for the business
         combination to be effected by the Merger as a pooling-of-
         interests for financial reporting purposes or (b) prevent the
         Merger from constituting a reorganization qualifying under the
         provisions of Section 368(a) of the Code.

                   3.8  Cardinal SEC Documents.  Cardinal has timely
         filed with the Commission all forms, reports, schedules,
         statements and other documents required to be filed by it since
         December 31, 1994 under the Exchange Act or the Securities Act
         (such documents, as supplemented and amended since the time of
         filing, collectively, the "Cardinal SEC Documents").  The
         Cardinal SEC Documents, including, without limitation, any
         financial statements or schedules included therein, at the time
         filed (and, in the case of registration statements and proxy
         statements, on the dates of effectiveness and the dates of
         mailing, respectively) (a) did not 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, and (b) except as set forth in Section
         3.8 to the Cardinal Disclosure Schedule, complied in all
         material respects with the 


                                    -10-

<PAGE>   15








         applicable requirements of the Exchange Act and the Securities
         Act, as the case may be.  The financial statements of Cardinal
         included in the Cardinal SEC Documents at the time filed (and,
         in the case of registration statements and proxy statements, on
         the dates of effectiveness and the dates of mailing,
         respectively) complied as to form in all material respects with
         applicable accounting requirements and with the published rules
         and regulations of the Commission with respect thereto, were
         prepared in accordance with generally accepted accounting
         principles applied on a consistent basis during the periods
         involved (except as may be indicated in the notes thereto or,
         in the case of unaudited statements, as permitted by Form 10-Q
         of the Commission), and fairly present (subject in the case of
         unaudited statements to normal, recurring audit adjustments)
         the consolidated financial position of Cardinal and its
         consolidated subsidiaries as at the dates thereof and the
         consolidated results of their operations and cash flows for the
         periods then ended.

              3.9  Registration Statement.  None of the information
         provided by Cardinal in writing for inclusion in the
         registration statement on Form S-4 (such registration statement
         as amended, supplemented or modified, the "Registration
         Statement") to be filed with the Commission by Cardinal under
         the Securities Act, including the prospectus relating to
         Cardinal Common Shares to be issued in the Merger (as amended,
         supplemented or modified, the "Prospectus") and the joint proxy
         statement and form of proxies relating to the vote of Bergen
         Shareholders with respect to the Merger and the vote of
         Cardinal Shareholders with respect to the Cardinal Shareholder
         Proposals (as amended, supplemented or modified, the "Joint
         Proxy Statement"), at the time the Registration Statement
         becomes effective or, in the case of the Joint Proxy Statement,
         at the date of mailing and at the date of the Bergen
         Shareholders Meeting or the Cardinal Shareholders Meeting
         (each, as hereinafter defined) to consider the Merger and the
         transactions contemplated thereby, will contain any untrue
         statement of a material fact or omit to state any material fact
         required to be stated therein or necessary in order to make the
         statements therein, in light of the circumstances under which
         they are made, not misleading.  Each of the Registration
         Statement and Joint Proxy Statement, except for such portions
         thereof that relate only to Bergen, will comply as to form in
         all material respects with the provisions of the Securities Act
         and Exchange Act.

                   3.10  Compliance with Law.  Cardinal and its
         subsidiaries are in compliance with, and at all times since
         September 30, 1994 have been in compliance with, all applicable
         laws, statutes, orders, rules, regulations, policies or
         guidelines promulgated, or judgments, decisions or orders
         entered by any Governmental Authority, including, without
         limitation, the Federal Prescription Drug Marketing Act and
         comparable or related state law provisions, the Federal
         Controlled Substances Act of 1970, the Food, Drug and Cosmetic
         Act (the "FDCA"), the Good Manufacturing Practices standards of
         the Food and Drug Administration (the "FDA"), federal Medicare
         and Medicaid statutes, including, without limitation, 42 U.S.C.
         Section 1320a-7b and 42 U.S.C. Section 1395nn or related state
         or local statutes or regulations, applicable state laws
         regulating pharmacy or wholesaling practices, the Occupational
         Safety and Health Act and the regulations promulgated
         thereunder (all such laws, statutes, orders, rules,
         regulations, policies, guidelines, judgments, decisions and
         orders, collectively, "Applicable Laws"), relating to Cardinal,
         its subsidiaries or their respective business or properties,
         except where the failure to be in compliance therewith
         (individually or in the aggregate) would not reasonably be
         expected to 


                                    -11-

<PAGE>   16








         have a Material Adverse Effect on Cardinal or where such non-
         compliance has been cured.  Except as disclosed in Section 3.10
         to the Cardinal Disclosure Schedule, no investigation or review
         by any Governmental Authority with respect to Cardinal or its
         subsidiaries is pending, or, to the knowledge of Cardinal,
         threatened, nor has any Governmental Authority indicated in
         writing an intention to conduct the same, other than those the
         outcome of which would not reasonably be expected to have a
         Material Adverse Effect on Cardinal.

                   3.11  Litigation.  Except as set forth in Section
         3.11 to the Cardinal Disclosure Schedule or in the Cardinal SEC
         Documents, there is no suit, claim, action, proceeding or
         investigation (an "Action") pending or, to the knowledge of
         Cardinal, threatened against Cardinal or any of its
         subsidiaries which, individually or in the aggregate, would
         have a Material Adverse Effect on Cardinal or a material
         adverse effect on the ability of Cardinal to consummate the
         transactions contemplated hereby.  Neither Cardinal nor any of
         its subsidiaries is subject to any outstanding order, writ,
         injunction or decree which, individually or in the aggregate,
         insofar as can be reasonably foreseen, could have a Material
         Adverse Effect on Cardinal or a material adverse effect on the
         ability of Cardinal to consummate the transactions contemplated
         hereby.  Except as set forth in Section 3.11 to the Cardinal
         Disclosure Schedule, since September 30, 1994, neither Cardinal
         nor any of its subsidiaries has been subject to any outstanding
         order, writ, injunction or decree relating to Cardinal's method
         of doing business or its relationship with past, existing or
         future users or purchasers of any goods or services of
         Cardinal.

                   3.12  Board Recommendation.  The Board of Directors
         of Cardinal, at a meeting duly called and held, has by
         unanimous vote of those directors present (who constituted
         100% of the directors then in office) (i) determined that this
         Agreement and the transactions contemplated hereby, including
         the Merger, taken together, are fair to and in the best
         interests of Cardinal and the Cardinal Shareholders, and (ii)
         resolved to recommend that the Cardinal Shareholders approve
         and authorize the Cardinal Shareholder Proposals and the
         transactions contemplated hereby.

                   3.13  No Material Adverse Change.  Except as
         disclosed in the Cardinal SEC Documents filed prior to the date
         of this Agreement, since June 30, 1996, there has been no
         change in the assets, liabilities, results of operations or
         financial condition of Cardinal which would constitute a
         Material Adverse Effect on Cardinal or any event, occurrence or
         development which would have a material adverse effect on the
         ability of Cardinal to consummate the transactions contemplated
         hereby.

                   3.14  Title to and Condition of Properties.
         Cardinal and its subsidiaries own or hold under valid leases
         all real property, plants, machinery and equipment necessary
         for the conduct of the business of Cardinal and its
         subsidiaries as presently conducted, except where the failure
         to own or so hold such property, plants, machinery and
         equipment would not reasonably be expected to have a Material
         Adverse Effect on Cardinal.

                   3.15  Undisclosed Liabilities.  Except (i) as and to
         the extent disclosed or reserved against on the restated
         consolidated balance sheet of Cardinal as of June 30, 1996
         included in the Cardinal SEC Documents, (ii) as incurred after
         the date thereof in the ordinary


                                    -12-

<PAGE>   17








         course of business consistent with prior practice and not
         prohibited by this Agreement or (iii) as set forth in Section
         3.15 to the Cardinal Disclosure Schedule, Cardinal, together
         with its subsidiaries, does not have any liabilities or
         obligations of any nature, whether known or unknown, absolute,
         accrued, contingent or otherwise and whether due or to become
         due, that, individually or in the aggregate, have or would have
         a Material Adverse Effect on Cardinal.

                   3.16  Operation of Cardinal's Business;
         Relationships.

                   (a)  Since March 31, 1997, through the date of this
         Agreement, neither Cardinal nor any of its subsidiaries has
         engaged in any transaction which, if done after execution of
         this Agreement, would violate in any material respect Section
         5.2(c) hereof except as set forth in Section 3.16(a) to the
         Cardinal Disclosure Schedule. 

                   (b)  Except as set forth in Section 3.16(b) to the
         Cardinal Disclosure Schedule, since January 1, 1997, no
         material customer of Cardinal or any of its subsidiaries has
         indicated that it will stop or materially decrease purchasing
         materials, products or services from Cardinal or its
         subsidiaries and no material supplier of Cardinal or any of its
         subsidiaries has indicated that it will stop or materially
         decrease the supply of materials, products or services to
         Cardinal or its subsidiaries, in each case, the effect of which
         would have a Material Adverse Effect on Cardinal.

                   3.17  Interested Stockholder or Acquiring Person.
         Neither Cardinal nor any of its affiliates is or has been an
         "Interested Stockholder" as such term is defined in the New
         Jersey Shareholders Protection Act (the "NJSPA") or an
         "Acquiring Person" as such term is defined in the Bergen Rights
         Agreement.

                                   ARTICLE IV.

                     REPRESENTATIONS AND WARRANTIES OF BERGEN

                   In order to induce Subcorp and Cardinal to enter into
         this Agreement, Bergen hereby represents and warrants to
         Cardinal and Subcorp that the statements contained in this
         Article IV are true, correct and complete. 

                   4.1  Organization and Standing.  Bergen is a
         corporation duly organized, validly existing and in good
         standing under the laws of the State of New Jersey with full
         corporate power and authority to own, lease, use and operate
         its properties and to conduct its business as and where now
         owned, leased, used, operated and conducted.  Each of Bergen
         and each subsidiary of Bergen is duly qualified to do business
         and in good standing in each jurisdiction in which the nature
         of the business conducted by it or the property it owns, leases
         or operates requires it to so qualify, except where the failure
         to be so qualified or in good standing in such jurisdiction
         would not reasonably be expected to have a Material Adverse
         Effect on Bergen.  Bergen is not in default in the performance,
         observance or fulfillment of any provision of its Certificate
         of Incorporation, as amended and restated (the "Bergen
         Certificate"), or its Bylaws, as in effect on the date hereof
         (the "Bergen Bylaws").  Bergen has heretofore furnished to
         Cardinal a complete and correct copy of the Bergen Certificate
         and the Bergen Bylaws.  Listed in Section 


                                    -13-

<PAGE>   18








         4.1 to the disclosure schedule delivered by Bergen to Cardinal
         and dated the date hereof (the "Bergen Disclosure Schedule") is
         each jurisdiction in which Bergen or a subsidiary of Bergen is
         qualified to do business and in good standing as of the date of
         the Agreement.

                   4.2  Subsidiaries.  Bergen does not own, directly or
         indirectly, any equity or other ownership interest in any
         corporation, partnership, joint venture or other entity or
         enterprise, except for the subsidiaries and other entities set
         forth in Section 4.2 to the Bergen Disclosure Schedule.  Except
         as set forth in Section 4.2 to the Bergen Disclosure Schedule,
         Bergen is not subject to any obligation or requirement to
         provide funds to or make any investment (in the form of a loan,
         capital contribution or otherwise) in any such entity that is
         not wholly owned by Bergen.  Bergen owns directly or indirectly
         each of the outstanding shares of capital stock (or other
         ownership interests having by their terms ordinary voting power
         to elect a majority of directors or others performing similar
         functions with respect to such subsidiary) of each of Bergen's
         subsidiaries.  Each of the outstanding shares of capital stock
         of each of Bergen's subsidiaries is duly authorized, validly
         issued, fully paid and nonassessable, and is owned, directly or
         indirectly, by Bergen free and clear of all liens, pledges,
         security interests, claims or other encumbrances.  The
         following information for each subsidiary of Bergen is set
         forth in Section 4.2 to the Bergen Disclosure Schedule, as
         applicable:  (i) its name and jurisdiction of incorporation or
         organization; (ii) for a subsidiary which is not wholly owned
         by Bergen, its authorized capital stock or share capital; and
         (iii) for a subsidiary which is not wholly owned by Bergen, the
         number of issued and outstanding shares of capital stock or
         share capital, the record owner(s) thereof to the extent known
         to Bergen and the number of issued and outstanding shares of
         capital stock or share capital beneficially owned by Bergen.
         Other than as set forth in Section 4.2 to the Bergen Disclosure
         Schedule, there are no outstanding subscriptions, options,
         warrants, puts, calls, agreements, understandings, claims or
         other commitments or rights of any type relating to the
         issuance, sale or transfer of any securities of any subsidiary
         of Bergen, nor are there outstanding any securities which are
         convertible into or exchangeable for any shares of capital
         stock of any subsidiary of Bergen, and neither Bergen nor any
         subsidiary of Bergen has any obligation of any kind to issue
         any additional securities of any subsidiary of Bergen or to pay
         for or repurchase any securities of any subsidiary of Bergen or
         any predecessor thereof.

                   4.3  Corporate Power and Authority.  Bergen has all
         requisite corporate power and authority to enter into and
         deliver this Agreement, to perform its obligations hereunder
         and, subject to approval of the Merger and the transactions
         contemplated hereby by Bergen Shareholders, to consummate the
         transactions contemplated by this Agreement.  The execution and
         delivery of this Agreement by Bergen have been duly authorized
         by all necessary corporate action on the part of Bergen,
         subject to approval of the Merger and the transactions
         contemplated hereby by Bergen Shareholders.  This Agreement has
         been duly executed and delivered by Bergen and constitutes the
         legal, valid and binding obligation of Bergen enforceable
         against it in accordance with its terms. 

                   4.4  Capitalization of Bergen.  As of July 31, 1997,
         Bergen's authorized capital stock consisted solely of (a)
         100,000,000 shares of Class A common stock, par value $1.50 per
         share ("Bergen Common Stock"), of which (i) 50,392,779 shares
         were issued and outstanding, (ii) 5,454,983 shares were issued
         and held in treasury (which does not include the shares
         reserved


                                    -14-

<PAGE>   19








         for issuance set forth in clause (iii) below) and no shares
         were held by subsidiaries of Bergen, (iii) 2,531,152 shares
         were reserved for issuance upon the exercise of outstanding
         options and no shares were reserved for issuance upon the
         conversion or exchange of convertible or exchangeable
         securities granted or issued by Bergen, (iv) 820,313 shares of
         Bergen Common Stock were reserved for issuance under the Bergen
         Elective Savings Retirement Plan and (v) 10,028,163 shares of
         Bergen Common Stock were reserved for future issuance under the
         Stock Option Agreement dated August 23, 1997 between Cardinal
         and Bergen (the "Bergen Stock Option Agreement"); and (b)
         3,000,000 shares of preferred stock, without par value ("Bergen
         Preferred Stock"), none of which was issued and outstanding or
         reserved for issuance, except for a series of 400,000 shares of
         Bergen Preferred Stock designated as Series A Junior
         Participating Preferred Stock reserved for issuance pursuant to
         the Bergen Rights Agreement (as defined in Section 4.25), none
         of which was issued and outstanding.  Each outstanding share of
         Bergen capital stock is duly authorized and validly issued,
         fully paid and nonassessable, and has not been issued in
         violation of any preemptive or similar rights.  Other than as
         set forth in the first sentence hereof, in Section 4.4 to the
         Bergen Disclosure Schedule or as contemplated by the Bergen
         Stock Option Agreement, there are no outstanding subscriptions,
         options, warrants, puts, calls, agreements, understandings,
         claims or other commitments or rights of any type relating to
         the issuance, sale, repurchase or transfer by Bergen of any
         securities of Bergen, nor are there outstanding any securities
         which are convertible into or exchangeable for any shares of
         capital stock of Bergen, and neither Bergen nor any subsidiary
         of Bergen has any obligation of any kind to issue any
         additional securities or to pay for or repurchase any
         securities of Bergen or any predecessor.  The Bergen Disclosure
         Schedule accurately sets forth as of August 7, 1997 the names
         of, and the number of shares of each class (including the
         number of shares issuable upon exercise of Bergen Options and
         the exercise price and vesting schedule with respect thereto)
         and the number of options held by, all holders of options to
         purchase Bergen capital stock.  Except as set forth in Section
         4.4 to the Bergen Disclosure Schedule, Bergen has no agreement,
         arrangement or understandings to register any securities of
         Bergen or any of its subsidiaries under the Securities Act or
         under any state securities law and has not granted registration
         rights to any person or entity (other than agreements,
         arrangements or understandings with respect to registration
         rights that are no longer in effect as of the date of this
         Agreement); copies of all such agreements have previously been
         provided to Cardinal.

                   4.5  Conflicts; Consents and Approvals.  Neither the
         execution and delivery of this Agreement or the Bergen Stock
         Option Agreement by Bergen, nor the consummation of the
         transactions contemplated hereby or thereby will:

                   (a)  conflict with, or result in a breach of any
              provision of, the Bergen Certificate or the Bergen Bylaws;

                   (b)  violate, or conflict with, or result in a breach
              of any provision of, or constitute a default (or an event
              which, with the giving of notice, the passage of time or
              otherwise, would constitute a default) under, or entitle
              any party (with the giving of notice, the passage of time
              or otherwise) to terminate, accelerate, modify or call a
              default under, or result in the creation of any lien,
              security interest, charge or encumbrance upon any of the
              properties or assets of Bergen under, any of the terms,
              conditions or provisions of any


                                    -15-

<PAGE>   20








              note, bond, mortgage, indenture, deed of trust, license,
              contract, undertaking, agreement, lease or other
              instrument or obligation to which Bergen or any of its
              subsidiaries is a party;

                   (c)  violate any order, writ, injunction, decree,
              statute, rule or regulation applicable to Bergen or any of
              its subsidiaries or any of their respective properties or
              assets; or

                   (d)  require any action or consent or approval of, or
              review by, or registration or filing by Bergen or any of
              its affiliates with, any third party or any Governmental
              Authority, other than (i) approval of the Merger and the
              transactions contemplated hereby by Bergen Shareholders,
              (ii) actions required by the HSR Act, (iii) registrations
              or other actions required under federal and state
              securities laws as are contemplated by this Agreement and
              (iv) consents or approvals of any Governmental Authority
              set forth in Section 4.5 to the Bergen Disclosure
              Schedule;

         except in the case of (b), (c) and (d) for any of the foregoing
         that would not, individually or in the aggregate, reasonably be
         expected to have a Material Adverse Effect on Bergen or a
         material adverse effect on the ability of the parties to
         consummate the transactions contemplated hereby. Other than as
         set forth on Schedule 4.5(b) to the Bergen Disclosure Schedule,
         to the knowledge of Bergen, neither the execution and delivery
         of this Agreement or the Bergen Stock Option Agreement by
         Bergen, nor the consummation of the transactions contemplated
         hereby or thereby will violate, or conflict with, or result in
         a breach of any provision of, or constitute a default (or an
         event which, with the giving of notice, the passage of time or
         otherwise, would constitute a default) under, or entitle any
         party (with the giving of notice, the passage of time or
         otherwise) to terminate, accelerate, modify or call a default
         under, or result in the creation of any lien, security
         interest, charge or encumbrance upon any of the material
         properties or assets of Bergen under, any of the terms,
         conditions or provisions of any material note, bond, mortgage,
         indenture, deed of trust, license, contract, undertaking,
         agreement, lease or other instrument or obligation to which
         Bergen or any of its subsidiaries is a party.

                   4.6  No Material Adverse Change.  Except as disclosed
         in the Bergen SEC Documents (as defined in Section 4.7 hereof)
         filed prior to the date of this Agreement, since September 30,
         1996, there has been no change in the assets, liabilities,
         results of operations or financial condition of Bergen which
         would constitute a Material Adverse Effect on Bergen or any
         event, occurrence or development which would have a material
         adverse effect on the ability of Bergen to consummate the
         transactions contemplated hereby.

                   4.7  Bergen SEC Documents.  Bergen has timely filed
         with the Commission all forms, reports, schedules, statements
         and other documents required to be filed by it since December
         31, 1994 under the Exchange Act or the Securities Act (such
         documents, as supplemented and amended since the time of
         filing, collectively, the "Bergen SEC Documents").  The Bergen
         SEC Documents, including, without limitation, any financial
         statements or schedules included therein, at the time filed
         (and, in the case of registration statements and proxy
         statements, on the dates of effectiveness and the dates of
         mailing, respectively) (a) did not 


                                    -16-

<PAGE>   21








         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,
         and (b) except as set forth in Section 4.7 to the Bergen
         Disclosure Schedule, complied in all material respects with the
         applicable requirements of the Exchange Act and the Securities
         Act, as the case may be.  The financial statements of Bergen
         included in the Bergen SEC Documents at the time filed (and, in
         the case of registration statements and proxy statements, on
         the dates of effectiveness and the dates of mailing,
         respectively) complied as to form in all material respects with
         applicable accounting requirements and with the published rules
         and regulations of the Commission with respect thereto, were
         prepared in accordance with generally accepted accounting
         principles applied on a consistent basis during the periods
         involved (except as may be indicated in the notes thereto or,
         in the case of unaudited statements, as permitted by Form 10-Q
         of the Commission), and fairly present (subject in the case of
         unaudited statements to normal, recurring audit adjustments)
         the consolidated financial position of Bergen and its
         consolidated subsidiaries as at the dates thereof and the
         consolidated results of their operations and cash flows for the
         periods then ended.  No subsidiary of Bergen is subject to the
         periodic reporting requirements of the Exchange Act or required
         to file any form, report or other document with the Commission,
         the NYSE, any other stock exchange or any other comparable
         Governmental Authority.

             4.8 Taxes. Except as set forth in Section 4.8 to the Bergen
         Disclosure Schedule and except for such matters that would not,
         individually or in the aggregate, reasonably be expected to
         have a Material Adverse Effect on Bergen:

             (a) Bergen and its subsidiaries (i) have duly filed all federal,
         state, local and foreign income, franchise, excise, real and
         personal property and other Tax Returns and reports (including,
         but not limited to, those filed on a consolidated, combined or
         unitary basis) required to have been filed by Bergen or its
         subsidiaries prior to the date hereof, all of which foregoing
         Tax Returns and reports are true and correct; (ii) have within
         the time and manner prescribed by Applicable Law paid or, prior
         to the Effective Time, will pay all Taxes, interest and
         penalties required to be paid in respect of the periods covered
         by such returns or reports or otherwise due to any federal,
         state, foreign, local or other taxing authority; (iii) have
         adequate reserves on their financial statements for any Taxes
         in excess of the amounts so paid; (iv) are not delinquent in
         the payment of any Tax and have not requested or filed any
         document having the effect of causing any extension of time
         within which to file any returns in respect of any fiscal year
         which have not since been filed; and (v) have not received
         written notice of any deficiencies for any Tax from any taxing
         authority, against Bergen or any of its subsidiaries for which
         there are not adequate reserves.  Neither Bergen nor any of its
         subsidiaries is the subject of any currently ongoing Tax audit.
         As of the date of this Agreement, there are no pending requests
         for waivers of the time to assess any Tax, other than those
         made in the ordinary course and for which payment has been made
         or there are adequate reserves.  With respect to any taxable
         period ended prior to September 30, 1992, all federal income
         Tax Returns including Bergen or any of its subsidiaries have
         been audited by the Internal Revenue Service or are closed by
         the applicable statute of limitations.  Neither Bergen nor any
         of its subsidiaries has waived any statute of limitations in
         respect of Taxes or agreed to any extension of time with
         respect to a Tax assessment or deficiency.  There are no liens
         with respect to Taxes upon any of the properties or 


                                    -17-

         assets, real or personal, tangible or intangible of Bergen or
         any of its subsidiaries (other than liens for Taxes not yet
         due).  No claim has ever been made in writing by an authority
         in a jurisdiction where none of Bergen and its subsidiaries
         files Tax Returns that Bergen or any of its subsidiaries is or
         may be subject to taxation by that jurisdiction.  Bergen has
         not filed an election under Section 341(f) of the Code to be
         treated as a consenting corporation. 

                   (b)  Neither Bergen nor any of its subsidiaries is
         obligated by any contract, agreement or other arrangement to
         indemnify any other person with respect to Taxes.  Neither
         Bergen nor any of its subsidiaries are now or have ever been a
         party to or bound by any agreement or arrangement (whether or
         not written and including, without limitation, any arrangement
         required or permitted by law) binding Bergen or any of its
         subsidiaries which (i) requires Bergen or any of its
         subsidiaries to make any Tax payment to (other than payments
         made prior to March 31, 1997 or payments which are adequately
         reserved on Bergen's balance sheet as of September 30, 1996
         included in the Bergen SEC Documents) or for the account of any
         other person, (ii) affords any other person the benefit of any
         net operating loss, net capital loss, investment Tax credit,
         foreign Tax credit, charitable deduction or any other credit or
         Tax attribute which could reduce Taxes (including, without
         limitation, deductions and credits related to alternative
         minimum Taxes) of Bergen or any of its subsidiaries, or (iii)
         requires or permits the transfer or assignment of income,
         revenues, receipts or gains to Bergen or any of its
         subsidiaries, from any other person.

                   (c)  Bergen and its subsidiaries have withheld and
         paid all Taxes required to have been withheld and paid in
         connection with amounts paid or owing to any employee,
         independent contractor, creditor, shareholder or other third
         party.

                   (d)  "Tax Returns" means returns, reports and forms
         required to be filed with any Governmental Authority of the
         United States or any other jurisdiction responsible for the
         imposition or collection of Taxes.

         state, local or foreign) based upon or measured by income and
         any other Tax whatsoever, including, without limitation, gross
         receipts, profits, sales, use, occupation, value added, ad
         valorem, transfer, franchise, withholding, payroll, employment,
         excise, or property Taxes, together with any interest or
         penalties imposed with respect thereto and (ii) any obligations
         under any agreements or arrangements with respect to any Taxes
         described in clause (i) above.

                   4.9  Compliance with Law.  Except as set forth in
         Section 4.9 to the Bergen Disclosure Schedule, Bergen is in
         compliance, and at all times since September 30, 1994 has been
         in compliance, with all Applicable Laws relating to Bergen or
         its business or properties, except where the failure to be in
         compliance with such Applicable Laws (individually or in the
         aggregate) would not reasonably be expected to have a Material
         Adverse Effect on Bergen or where such non-compliance has been
         cured.  Except as disclosed in Section 4.9 to the Bergen
         Disclosure Schedule, no investigation or review by any
         Governmental Authority with respect to Bergen is pending, or,
         to the knowledge of Bergen, threatened, nor has any
         Governmental


                                    -18-

<PAGE>   23








         Authority indicated in writing an intention to conduct the
         same, other than those the outcome of which would not
         reasonably be expected to have a Material Adverse Effect on
         Bergen. 

                   4.10  Intellectual Property.  Except as would not,
         individually or in the aggregate, reasonably be expected to
         have a Material Adverse Effect on Bergen, Bergen owns or
         possesses adequate licenses or other valid rights to use all
         patents, patent rights, trademarks, trademark rights, trade
         names, trade dress, trade name rights, copyrights, service
         marks, trade secrets, applications for trademarks and for
         service marks, know-how and other proprietary rights and
         information used or held for use in connection with the
         businesses of Bergen ("Intellectual Property") as currently
         conducted, and there has not been any written assertion or
         claim against Bergen challenging the validity or the use by
         Bergen of any of the foregoing.  Other than licenses generally
         available to the public at reasonable cost and material
         licenses or rights to use set forth in Section 4.10 to the
         Bergen Disclosure Schedule, no material licenses or other valid
         rights to use all patents, patent rights, trademarks, trademark
         rights, trade names, trade dress, trade name rights,
         copyrights, service marks, trade secrets, applications for
         trademarks and for service marks, know-how and other
         proprietary rights is necessary for the operation of the
         business of Bergen in substantially the same manner as such
         business is presently conducted.  The conduct of the businesses
         of Bergen as currently conducted does not conflict with or
         infringe upon any patent, patent right, license, trademark,
         trademark right, trade dress, trade name, trade name right,
         service mark or copyright of any third party except for any
         conflict or infringement that, individually or in the
         aggregate, would not reasonably be expected to have a Material
         Adverse Effect on Bergen.  Except as would not, individually or
         in the aggregate, reasonably be expected to have a Material
         Adverse Effect on Bergen, there are no infringements of any of
         the Intellectual Property owned by or licensed by or to Bergen
         and the Intellectual Property is not the subject to any pending
         Action.  

                   4.11  Title to and Condition of Properties.  Bergen
         owns or holds under valid leases all real property, plants,
         machinery and equipment necessary for the conduct of the
         business of Bergen as presently conducted, except where the
         failure to own or so hold such property, plants, machinery and
         equipment would not reasonably be expected to have a Material
         Adverse Effect on Bergen.  

                   4.12  Registration Statement; Joint Proxy Statement.
         None of the information provided in writing by Bergen for
         inclusion in the Registration Statement at the time it becomes
         effective or, in the case of the Joint Proxy Statement, at the
         date of mailing and at the date of the Bergen Shareholders
         Meeting or the Cardinal Shareholders Meeting, will 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.  The Registration
         Statement and Joint Proxy Statement, except for such portions
         thereof that relate only to Cardinal and its subsidiaries, will
         each comply as to form in all material respects with the
         provisions of the Securities Act and the Exchange Act.

                   4.13  Litigation.  Except as set forth in Section
         4.13 to the Bergen Disclosure Schedule or specifically
         identified in the Bergen SEC Documents filed prior to the date
         of the Agreement, there is no Action pending or, to the
         knowledge of Bergen, threatened against 


                                    -19-

<PAGE>   24








         Bergen or any executive officer or director of Bergen which,
         individually or in the aggregate, would have a Material Adverse
         Effect on Bergen or a material adverse effect on the ability of
         Bergen to consummate the transactions contemplated hereby.
         Bergen is not subject to any outstanding order, writ,
         injunction or decree which, individually or in the aggregate,
         insofar as can be reasonably foreseen, could have a Material
         Adverse Effect on Bergen or a material adverse effect on the
         ability of Bergen to consummate the transactions contemplated
         hereby.  Except as set forth in Section 4.13 to the Bergen
         Disclosure Schedule, since September 30, 1994, Bergen has not
         been subject to any outstanding order, writ, injunction or
         decree relating to Bergen's method of doing business or its
         relationship with past, existing or future users or purchasers
         of any goods or services of Bergen.  

                   4.14  Brokerage and Finder's Fees; Expenses.  Except
         for Bergen's obligations to Merrill Lynch & Co., Inc. ("Merrill
         Lynch") (copies of all written agreements relating to such
         obligations having previously been provided to Cardinal),
         neither Bergen nor any stockholder, director, officer or
         employee thereof, has incurred or will incur on behalf of
         Bergen, any brokerage, finder's or similar fee in connection
         with the transactions contemplated by this Agreement. 

                   4.15  Accounting Matters; Reorganization.  Neither
         Bergen nor any of its affiliates has taken or agreed to take
         any action that (without giving effect to any actions taken or
         agreed to be taken by Cardinal or any of its affiliates) would
         (a) prevent Cardinal from accounting for the business
         combination to be effected by the Merger as a pooling-of-
         interests for financial reporting purposes or (b) prevent the
         Merger from constituting a reorganization qualifying under the
         provisions of Section 368(a) of the Code.

                   "Plans" means all employee welfare benefit plans
              within the meaning of Section 3(1) of ERISA and all
              employee pension benefit plans within the meaning of
              Section 3(2) of ERISA sponsored or maintained by Bergen or
              any of its subsidiaries or to which Bergen or any of its
              subsidiaries contributes or is obligated to contribute.  

                   "Withdrawal Liability" means liability to a
              Multiemployer Plan as a result of a complete or partial
              withdrawal from such Multiemployer Plan, as those terms
              are defined in Part I of Subtitle E of Title IV of ERISA.

                   (b)  With respect to each Plan, Bergen has provided
         to Cardinal a true, correct and complete copy of the following
         (where applicable):  (i) each writing constituting a part of
         such Plan, including without limitation all plan documents,

         vehicles; (ii) the most recent Annual Report (Form 5500 Series)

                   (c)  Except as set forth in Section 4.16(c) to the
         Bergen Disclosure Schedule, the Internal Revenue Service has
         issued a favorable determination letter with respect to each
         Plan that is intended to be a "qualified plan" within the
         meaning of Section 401(a) of the Code (a "Qualified Plan") and
         there are no existing circumstances nor any events that have
         occurred that would adversely affect the qualified status of
         any Qualified Plan or the related trust in a manner that would
         have a Material Adverse Effect.

                   (d)  All contributions required to be made to any
         Plan by Applicable Laws or by any plan document or other
         contractual undertaking, and all premiums due or payable with
         respect to insurance policies funding any Plan, before the date
         hereof have been made or paid in full on or before the final
         due date thereof and through the Closing Date will be made or
         paid in full on or before the final due date thereof.

                   (e)  Bergen and its subsidiaries have complied, and
         are now in compliance, in all material respects, with all
         provisions of ERISA, the Code and all laws and regulations
         applicable to the Plans.  Each Plan has been operated in
         material compliance with its terms.  There is not now, and
         there are no existing circumstances that would give rise to,
         any requirement for the posting of security with respect to a
         Plan or the imposition of any lien on the assets of Bergen or
         any of its subsidiaries under ERISA or the Code.

                   (f)  Except as set forth in Section 4.16(f) to the
         Bergen Disclosure Schedule, no Plan is a "multiemployer plan"
         within the meaning of Section 4001(a)(3) of ERISA (a
         "Multiemployer Plan") or a plan that has two or more
         contributing sponsors at least two of whom are not under common
         control, within the meaning of Section 4063 of ERISA (a
         "Multiple Employer Plan"), nor has Bergen or any of its
         subsidiaries or any of their respective ERISA Affiliates, at
         any time within six years before the date hereof, contributed
         to or been obligated to contribute to any Multiemployer Plan or
         Multiple Employer Plan.  With respect to each Multiemployer
         Plan: (i) neither Bergen nor any of its ERISA Affiliates has
         incurred any Withdrawal Liability that has not been satisfied
         in full; and (ii) neither Bergen nor any ERISA 


                                    -21-


<PAGE>   26







         Affiliate has received any notification, nor has any reason to
         believe, that any such plan is in reorganization, is insolvent,
         has been terminated, or would be in reorganization, to be
         insolvent, or to be terminated.  Except for Multiemployer
         Plans, no Plan is subject to Title IV or Section 302 of ERISA
         or Section 412 or 4971 of the Code.

                   (g)  There does not now exist, and there are no
         currently existing circumstances that would result in, any
         material Controlled Group Liability that would be a liability
         of Bergen or any of its subsidiaries following the Closing.
         Without limiting the generality of the foregoing, neither
         Bergen nor any of its subsidiaries nor any of their respective
         ERISA Affiliates has engaged in any transaction described in
         Section 4069 or Section 4204 of ERISA.

                   (h)  Except for health continuation coverage as
         required by Section 4980B of the Code or Part 6 of Title I of
         ERISA and except as set forth in Section 4.16(h) to the Bergen
         Disclosure Schedule, neither Bergen nor any of its subsidiaries
         has any material liability for life, health, medical or other
         welfare benefits to former employees or beneficiaries or
         dependents thereof.

                   (i)  Except as disclosed in Section 4.16(i) to the
         Bergen Disclosure Schedule, neither the execution and delivery
         of this Agreement nor the consummation of the transactions
         contemplated hereby will result in, cause the accelerated
         vesting or delivery of, or increase the amount or value of, any
         payment or benefit to any employee, officer, director or
         consultant of Bergen or any of its subsidiaries.  Without
         limiting the generality of the foregoing, except as set forth
         in Section 4.16(i) to the Bergen Disclosure Schedule, no amount
         paid or payable by Bergen or any of its subsidiaries in
         connection with the transactions contemplated hereby either
         solely as a result thereof or as a result of such transactions
         in conjunction with any other events will be an "excess
         parachute payment" within the meaning of Section 280G of the
         Code.

                   (j)  Except as disclosed in Section 4.16(j) to the
         Bergen Disclosure Schedule, there are no pending or to the
         knowledge of Bergen threatened claims (other than claims for
         benefits in the ordinary course), lawsuits or arbitrations
         which have been asserted or instituted against the Plans, any
         fiduciaries thereof with respect to their duties to the Plans
         or the assets of any of the trusts under any of the Plans which
         would result in any material liability of Bergen or any of its
         subsidiaries to the Pension Benefit Guaranty Corporation, the
         Department of Treasury, the Department of Labor or any
         Multiemployer Plan.

                   (k)  Section 4.16(k) to the Bergen Disclosure
         Schedule sets forth a list of each employment, severance or
         similar agreement under which Bergen or any of its subsidiaries
         is or could become obligated to provide compensation or
         benefits in excess of $200,000 in any one calendar year, and
         Bergen has provided to Cardinal a copy of each such agreement. 

                   (l)  The Bergen Amended and Restated Supplemental
         Executive Retirement Plan (the "SERP") and the Amended and
         Restated Bergen Capital Accumulation Plan (the "CAP") have been
         amended, and the Company has executed an amendment (the "Trust
         Amendment") to the Master Trust Agreement for Bergen Brunswig
         Corporation Executive Deferral Plans dated as of December 27,
         1994, between Bergen and Wachovia Bank of North Carolina, N.A.
         (the "Trustee"), which amendment is subject to execution by the
         Trustee.  Such amendments provide 


                                    -22-

<PAGE>   27








         that, except as set forth in the immediately following
         sentence, (i) the consummation of the Merger shall not
         effectuate a "Change in Control" within the meaning thereof,
         and (ii) effective as of the Effective Time, all provisions
         thereof that relate to a "Change in Control" shall be null and
         void and of no further force and effect, as if deleted.
         Notwithstanding the foregoing, the consummation of the Merger
         shall effectuate a "Change in Control" solely for purposes of
         giving effect to (A) the provisions of Section 5.1(b)(i) of the
         SERP that call for full vesting of the "Accrued Benefit" of
         each "Participant" upon a "Change in Control" (as those terms
         are defined in the SERP, as amended to exclude from
         participation, contingent upon consummation of the Merger,
         certain executives who previously participated therein), and
         (B) the provisions of Section 5.4(a)(F) of the CAP that call
         for the benefit of a "Participant" that is "Accrued" as of a
         "Change in Control" (without giving effect to clauses (A)-(E)
         of Section 5.4(a)) to become fully "Vested" as of a "Change in
         Control" (as those terms are defined in the CAP, as similarly
         amended to exclude from participation, contingent upon
         consummation of the Merger, certain executives who previously

         a default under or permit the termination of, any such Contract
         or Material Contract except such violations or defaults under
         or terminations which, individually or in the aggregate, would

         Bergen.  Set forth in Section 4.17(j) to the Bergen Disclosure
         Schedule is a description of any material changes to the amount
         and terms of the indentures of Bergen and its subsidiaries from

         contracts or collective bargaining agreements with any persons
         employed by Bergen or any persons otherwise performing services
         primarily for Bergen.  There is no labor strike, dispute or

         Section 4.20(a) to the Bergen Disclosure Schedule. 

                   (b)  Except as set forth in Section 4.20(b) to the

         from Bergen and no material supplier of Bergen has indicated
         that it will stop or materially decrease the supply of
         materials, products or services to Bergen, in each case, the

         business as it is now being conducted (collectively, the
         "Bergen Permits"), except where the failure to be in possession
         of such Bergen Permits would not, individually or in the
         aggregate, reasonably be expected to have a Material Adverse
         Effect on Bergen or a material adverse effect on the ability of
         the parties to consummate the transactions contemplated hereby,
         and there is no Action pending or, to the knowledge of Bergen,
         threatened regarding any of the Bergen Permits which, if
         successful, would have Material Adverse Effect on Bergen or a
         material adverse effect on the ability of the parties to
         consummate the transactions contemplated hereby.  Bergen is not
         in conflict with, or in default or violation of any of the
         Bergen Permits, except for any such conflicts, defaults or
         violations which, individually or in the aggregate, would not
         reasonably be expected to have a Material Adverse Effect on

              statement to the FDA or any similar governmental agency,
              failed to disclose a material fact required to be
              disclosed to the FDA or similar governmental agency, or
              committed an act, made a statement or failed to make a

              respecting "Fraud, Untrue Statements of Material Facts,
              Bribery, and Illegal Gratuities" or similar governmental
              policy, rule, regulation or law;

              of any jurisdiction; and

                   (iv)  none of Bergen or any of its officers (during
              the term of such person's employment by Bergen),
              subsidiaries or affiliates has been convicted of any crime

              arguments, opinions and proposals made or submitted by or
              on behalf of any party hereto in connection with
              proceedings under or relating to the HSR Act or other
              Antitrust Laws.

                        (ii)  Each of Cardinal and Bergen shall use all
              reasonable efforts to resolve such objections, if any, as
              may be asserted by any Governmental Authority with respect
              to the transactions contemplated by this Agreement under
              the HSR Act, the Sherman Act, as amended, the Clayton Act,
              as amended, the Federal Trade Commission Act, as amended,
              and any other federal, state or foreign statues, rules,
              regulations, orders, decrees, administrative or judicial
              doctrines or other laws that are designed to prohibit,
              restrict or regulate actions having the purpose or effect
              of monopolization or restraint of trade (collectively,
              "Antitrust Laws").  In connection therewith, if any
              administrative or judicial action or proceeding is
              instituted (or threatened to be instituted) challenging
              any transaction contemplated by this Agreement as
              violative of any Antitrust Law, each of Cardinal and
              Bergen shall cooperate and use all reasonable efforts
              vigorously to contest and resist any such action or
              proceeding, including any legislative, administrative or
              judicial action, and to have vacated, lifted, reversed, or
              overturned any decree, judgment, injunction or other order
              whether temporary, preliminary or permanent (each an
              "Order"), that is in effect and that prohibits, prevents,
              or restricts consummation of the Merger or any other
              transactions contemplated by this Agreement, including,
              without limitation, by vigorously pursuing all available
              avenues of administrative and judicial appeal and all
              available legislative action, unless by mutual agreement
              Cardinal and Bergen decide that litigation is not in their
              respective best interests.  Notwithstanding the foregoing
              or any other provision of this Agreement, nothing in this
              Section 5.1(a) shall limit a party's right to terminate
              this Agreement pursuant to Section 7.1, so long as such
              party has up to then complied in all material respects
              with its obligations under this Section 5.1(a).  Each of
              Cardinal and Bergen shall use all reasonable efforts to
              take such action as may be required to cause the
              expiration of the notice periods under the HSR Act or
              other Antitrust Laws with respect to such transactions as
              promptly as possible after the execution of this
              Agreement.  

                        (iii)  Each of the parties agrees to use all
              reasonable efforts to take, or cause to be taken, all
              actions, and to do, or cause to be done, and to assist and
              cooperate with the other parties in doing, all things
              necessary, proper or advisable to consummate and make
              effective, in the most expeditious manner practicable, the
              Merger and the other transactions contemplated by this
              Agreement, including (A) the obtaining of all other
              necessary actions or nonactions, waivers, consents,
              licenses, permits, authorizations, orders and approvals
              from Governmental Authorities and the making of all other
              necessary registrations and filings (including filings
              under the New Jersey Industrial Site Recovery Act, if
              applicable, and other filings with Governmental
              Authorities, if any), (B) the obtaining of all consents,
              approvals or waivers from third parties related to or
              required in connection with the Merger that are necessary
              to consummate the Merger and the transactions contemplated
              by this Agreement or required to prevent a Material
              Adverse Effect on Cardinal or Bergen from occurring prior
              to or after the Effective Time, (C) the preparation of the
              Joint Proxy Statement, the Prospectus and the Registration
              Statement, (D) the taking of all action necessary to
              ensure that it is a "poolable entity" eligible to
              participate in a transaction to be accounted for as a
              pooling of interests for financial reporting purposes and
              to ensure that the Merger constitutes a tax-free
              reorganization within the meaning of Section 368(a)(1)(A),
              and (E) the execution and delivery of any additional


                                    -29-

<PAGE>   34








              instruments necessary to consummate the transaction
              contemplated by, and to fully carry out the purposes of,
              this Agreement.

                        (iv)  Notwithstanding anything to the contrary
              in this Agreement, neither Cardinal nor Bergen shall be
              required to hold separate (including by trust or
              otherwise) or divest any of their respective businesses or
              assets, provided , however, that unless Cardinal and
              Bergen otherwise agree, if required to avoid an HSR
              Authority instituting an Action challenging the
              transactions under this Agreement under the Antitrust Laws
              and seeking to enjoin or prohibit the consummation of any
              of the transactions contemplated by this Agreement,
              Cardinal shall and, at the direction of Cardinal, Bergen
              shall, hold separate (including by trust or otherwise) or
              divest any of their respective businesses or assets, or
              take or agree to take any action or agree to any
              limitation required to avoid an HSR Authority instituting
              an Action challenging the transactions under this
              Agreement under the Antitrust Laws and seeking to enjoin
              or prohibit the consummation of any of the transactions
              contemplated hereby unless such action would reasonably be
              expected to have a material adverse effect on the assets,
              liabilities, results of operations or financial condition
              of Cardinal combined with the Surviving Corporation after
              the Effective Time, or would reasonably be expected to
              substantially impair the overall benefits expected, as of
              the date hereof, to be realized from consummation of the
              Merger.  Notwithstanding any other provision of this
              Section 5.1(a)(iv) neither party shall be required to (i)
              waive any of the conditions to the Merger set forth in
              Article VI of this Agreement as they apply to such party,
              or (ii) divest any of their respective businesses or
              assets if the divestitures would be required to be
              consummated prior to the Effective Time.

                   (b)  Pooling-of-Interests.  Each of the parties
         agrees that it shall not, and shall not permit any of its
         subsidiaries to, take any actions which would, or would be
         reasonably likely to, prevent Cardinal from accounting, and
         shall use its best efforts (including, without limitation,
         providing appropriate representation letters to Cardinal's
         accountants) to allow Cardinal to account, for the Merger in
         accordance with the pooling-of-interests method of accounting
         under the requirements of Opinion No. 16 "Business
         Combinations" of the Accounting Principles Board of the
         American Institute of Certified Public Accountants, as amended
         by applicable pronouncements by the Financial Accounting
         Standards Board, and all related published rules, regulations
         and policies of the Commission ("APB No. 16"), and to obtain a
         letter, in form and substance reasonably satisfactory to
         Cardinal, from Deloitte & Touche LLP dated the date of the
         Effective Time and, if requested by Cardinal, dated the date of
         the Joint Proxy Statement stating that they concur with
         management's conclusion that the Merger will qualify as a
         transaction to be accounted for by Cardinal in accordance with
         the pooling of interests method of accounting under the
         requirements of APB No. 16.

                   (c)  Tax-Free Treatment.  Each of the parties shall
         use its best efforts to cause the Merger to constitute a tax-
         free "reorganization" under Section 368(a) of the Code and to
         cooperate with one another in obtaining an opinion from
         Lowenstein, Sandler, Kohl, Fisher & Boylan, P.A. ("Lowenstein,
         Sandler"), counsel to Bergen, as provided for in Section
         6.2(d).  In connection therewith, each of Cardinal and Bergen
         shall deliver to Lowenstein, Sandler


                                    -30-

<PAGE>   35








         representation letters and Bergen shall use all reasonable
         efforts to obtain representation letters from appropriate
         shareholders of Bergen and shall deliver any such letters
         obtained to Lowenstein, Sandler, in each case in form and
         substance reasonably satisfactory to Lowenstein, Sandler.

                   (d)  Public Announcements.  The initial press release
         concerning the Merger and the transactions contemplated hereby
         shall be a joint press release, which shall state, among other
         matters, that subject to the consummation of the transactions
         contemplated hereby, Robert E. Martini shall be appointed
         Chairman of the Board of Directors of Cardinal to serve in such
         office until the annual meeting of Cardinal Shareholders in the
         year 2000.  Unless otherwise required by Applicable Laws or
         requirements of the NYSE (and in that event only if time does
         not permit), at all times prior to the earlier of the Effective
         Time or termination of this Agreement pursuant to Section 7.1,
         Cardinal and Bergen shall consult with each other before
         issuing any press release with respect to the Merger and shall
         not issue any such press release prior to such consultation.

                   5.2  Covenants of Cardinal.

                   (a)  Cardinal Shareholders Meeting.  Cardinal shall
         take all action in accordance with the federal securities laws,
         the Ohio Revised Code and the Cardinal Articles and Code of
         Regulations, as amended and restated, necessary to convene a
         special meeting of Cardinal Shareholders (the "Cardinal
         Shareholders Meeting") to be held on the earliest practical
         date determined by Cardinal, subject to the consent of Bergen
         (which shall not be unreasonably withheld), and to obtain the
         consent and approval of Cardinal Shareholders with respect to
         the Cardinal Shareholder Proposals and the transactions
         contemplated hereby, including recommending approval of the
         Cardinal Shareholder Proposals and transactions contemplated by
         this Agreement to the Cardinal Shareholders as set forth in
         Section 3.12 of this Agreement.

                   (b)  Preparation of Registration Statement.  Cardinal
         shall, as soon as is reasonably practicable, prepare the Joint
         Proxy Statement for filing with the Commission on a
         confidential basis.  Consistent with the timing for the
         Cardinal Shareholders Meeting and the Bergen Shareholders
         Meeting as determined by Cardinal, subject to the consent of
         Bergen (which shall not be unreasonably withheld), Cardinal
         shall prepare and file the Registration Statement with the
         Commission as soon as is reasonably practicable following
         clearance of the Joint Proxy Statement by the Commission and
         reasonable approval of the Joint Proxy Statement by Bergen and
         shall use all reasonable efforts to have the Registration
         Statement declared effective by the Commission as promptly as
         practicable and to maintain the effectiveness of the
         Registration Statement through the Effective Time.  If, at any
         time prior to the Effective Time, Cardinal shall obtain
         knowledge of any information pertaining to Cardinal contained
         in or omitted from the Registration Statement that would
         require an amendment or supplement to the Registration
         Statement or the Joint Proxy Statement, Cardinal will so advise
         Bergen in writing and will promptly take such action as shall
         be required to amend or supplement the Registration Statement
         and/or the Joint Proxy Statement.  Cardinal shall promptly
         furnish to Bergen all information concerning it as may be
         required for the Joint Proxy Statement and any supplements or
         amendments thereto.  Cardinal shall cooperate with Bergen in
         the preparation of the Joint


                                    -31-

<PAGE>   36








         Proxy Statement in a timely fashion and shall use all
         reasonable efforts to assist Bergen in clearing the Joint Proxy
         Statement with the Staff of the Commission, such Joint Proxy
         Statement to include the recommendation of the Cardinal Board
         of Directors referred to in Section 3.12 above.  Cardinal also
         shall take such other reasonable actions (other than qualifying
         to do business in any jurisdiction in which it is not so
         qualified) required to be taken under any applicable state
         securities laws in connection with the issuance of Cardinal
         Common Shares in the Merger. 

                   (c)  Conduct of Cardinal's Operations.  During the
         period from the date of this Agreement to the Effective Time,
         Cardinal shall use its reasonable efforts to maintain and
         preserve its business organization and to retain the services
         of its officers and key employees and maintain relationships
         with customers, suppliers and other third parties to the end
         that their goodwill and ongoing business shall not be impaired
         in any material respect.  Without limiting the generality of
         the foregoing, during the period from the date of this
         Agreement to the Effective Time, Cardinal shall not, except as
         otherwise expressly contemplated by this Agreement and the
         transactions contemplated hereby or as set forth in Section
         5.2(c) to the Cardinal Disclosure Schedule, without the prior
         written consent of Bergen:

                        (i)  change any method or principle of
              accounting in a manner that is inconsistent with past
              practice except to the extent required by generally
              accepted accounting principles as advised by Cardinal's 
              regular independent accountants;

                        (ii)  take any action that could likely result
              in the representations and warranties set forth in Article
              III becoming false or inaccurate in any material respect;

                        (iii)  make any changes in the Cardinal Articles
              that would adversely affect in any material respect the
              rights and preferences of the holders of Cardinal Common
              Shares or make any changes in the Amended and Restated
              Certificate of Incorporation of Subcorp;

                        (iv)  acquire a material amount of assets or
              capital stock of any other person if such acquisition
              would materially and adversely affect the ability of
              Section 6.1(b) to be satisfied on or prior to April 30,
              1998 (and, in any case, Cardinal agrees to give Bergen
              reasonable prior notice of any acquisition of a material
              amount of assets or capital stock of any other person);

                        (v)  permit or cause any subsidiary to do any of
              the foregoing or agree or commit to do any of the
              foregoing; or

                        (vi)  agree in writing or otherwise to take any
              of the foregoing actions.

                   (d)  Indemnification; Directors' and Officers'
         Insurance.  

                        (i)  From and after the Effective Time, Cardinal
              shall cause (including, to the extent required, providing
              sufficient funding to enable the Surviving Corporation to
              satisfy all of its obligations under this Section
              5.2(d)(i)), the Surviving Corporation to 


                                    -32-

<PAGE>   37








         indemnify, defend and hold harmless the present and former
         officers and directors of Bergen in respect of acts or
         omissions occurring prior to the Effective Time to the fullest
         extent provided or permitted under the Bergen Certificate, as
         amended and restated, the Bergen Bylaws, and the
         indemnification agreements disclosed in Section 5.2(d) to the
         Bergen Disclosure Schedule in effect on the date hereof.

                        (ii)  Cardinal shall use all reasonable efforts
              to cause the Surviving Corporation or Cardinal to obtain
              and maintain in effect for a period of six years after the
              Effective Time policies of directors' and officers'
              liability insurance at no cost to the beneficiaries
              thereof with respect to acts or omissions occurring prior
              to the Effective Time with substantially the same coverage
              and containing substantially similar terms and conditions
              as existing policies; provided, however, that neither the
              Surviving Corporation nor Cardinal shall be required to
              pay an aggregate premium for such insurance coverage in
              excess of 325% of the amount set forth in Section 4.17(k)
              to the Bergen Disclosure Schedule.

                        (iii)  Cardinal covenants and agrees from and
              after the Effective Time to (A) provide to the directors
              of Bergen who become directors of Cardinal directors' and
              officers' liability insurance on the same basis and to the
              same extent as that, if any, provided to other directors
              of Cardinal, and (B) enter into indemnification agreements
              with the directors of Bergen who become directors of
              Cardinal on terms entered into with other directors of
              Cardinal generally.

                   (e)  Merger Sub.  Prior to the Effective Time,
         Subcorp shall not conduct any business or make any investments
         other than as specifically contemplated by this Agreement and
         will not have any assets (other than a de minimis amount of
         cash paid to Subcorp for the issuance of its stock to Cardinal)
         or any material liabilities.

                   (f)  NYSE Listing.  Cardinal shall use its reasonable
         efforts to cause the Cardinal Common Shares issuable pursuant
         to the Merger (including, without limitation, the Cardinal
         Common Shares issuable upon the exercise of the Cardinal
         Exchange Options) to be approved for listing on the NYSE,
         subject to official notice of issuance, prior to the Effective
         Time.

                   (g)  Access.  Cardinal shall permit representatives
         of Bergen to have appropriate access at all reasonable times to
         Cardinal's premises, properties, books, records, contracts,
         documents, customers and suppliers.  Information obtained by
         Bergen pursuant to this Section 5.2(g) shall be subject to the
         provisions of the confidentiality agreement between Cardinal
         and Bergen dated July 23, 1997 (the "Confidentiality
         Agreement"), which agreement remains in full force and effect.
         No investigation conducted pursuant to this Section 5.2(g)
         shall affect or be deemed to modify any representation or
         warranty made in this Agreement.

                   (h)  Board of Directors of Cardinal.  The Board of
         Directors of Cardinal shall take all action necessary
         immediately following the Effective Time to elect each of
         Robert E. Martini and Donald R. Roden and two other persons
         from the Board of Directors of Bergen as of the date of this
         Agreement (designated by Robert E. Martini and reasonably
         acceptable to Cardinal) as a director of Cardinal (with Messrs.
         Robert E. Martini and Donald R. Roden being


                                    -33-

<PAGE>   38








         assigned to the class of directors whose term of office expires
         at Cardinal's third annual meeting of shareholders after the
         Effective Time and second annual meeting of shareholders after
         the Effective Time, respectively, and the other two persons
         being assigned to the class or classes of directors with a
         vacancy (other than those vacancies to be filled by Robert E.
         Martini and Donald R. Roden) and with the longest term of
         office available) effective as of the Effective Time, for a
         term expiring at Cardinal's next annual meeting of stockholders
         following the Effective Time at which the term of the class to
         which such director belongs expires, subject to being
         renominated as a director at the discretion of Cardinal's Board
         of Directors.  The Board of Directors of Cardinal shall take
         all action necessary immediately following the Effective Time
         to (i) elect Robert E. Martini as the Chairman of the Board of
         Cardinal; (ii) elect Robert D. Walter as the Chairman of the
         Executive Committee of the Board of Directors of Cardinal;

         hold such offices until his successor is elected and qualified,
         subject to being reelected or reappointed to such positions at
         the discretion of Cardinal's Board of Directors.

                   (i)  Corporate Name.  Subject to approval of the
         holders of Cardinal Common Shares (the "Cardinal Shareholders")
         at the Cardinal Shareholders Meeting of an amendment to Article

         following the Effective Time, Article First of the Cardinal
         Articles shall read "The name of the corporation shall be
         'Cardinal Bergen Health, Inc.'"  At any time prior to the
         Cardinal Shareholders Meeting, Cardinal and Bergen may agree to
         change the proposed name for Cardinal following the Effective
         Time.

                   (j)  Affiliates of Cardinal.   Cardinal shall cause
         each such person who may be at the Effective Time or was on the
         date hereof an "affiliate" of Cardinal for purposes of
         applicable accounting releases of the Commission with respect
         to pooling of interests accounting treatment, to execute and
         deliver to Bergen no less than 30 days prior to the date of the
         Cardinal Shareholders Meeting, the written undertakings in the
         form attached hereto as Exhibit A-2 (the "Cardinal Affiliate
         Letter").

                   (k)  Notification of Certain Matters.  Cardinal shall
         give prompt notice to Bergen of (i) the occurrence or non-
         occurrence of any event the occurrence or non-occurrence of
         which would cause any Cardinal representation or warranty
         contained in this Agreement to be untrue or inaccurate at or
         prior to the Effective Time in any material respect and (ii)
         any material failure of Cardinal to comply with or satisfy any
         covenant, condition or agreement to be complied with or
         satisfied by it hereunder; provided, however, that the delivery
         of any notice pursuant to this Section 5.2(k) shall not limit
         or otherwise affect the remedies available hereunder to Bergen.

                   (l)  Employees and Employee Benefit.  From and after
         the Effective Time, Cardinal shall treat all service by Bergen
         Employees (as defined below) with Bergen and their respective
         predecessors prior to the Effective Time for all purposes as
         service with Cardinal (except to the extent such treatment
         would result in duplicative accrual on or after the Closing
         Date of benefits for the same period of service), and, with
         respect to any medical or dental


                                    -34-

         benefit plan in which Bergen Employees participate after the
         Effective Time, Cardinal shall waive or cause to be waived any
         pre-existing condition exclusions and actively-at-work
         requirements (provided, however, that no such waiver shall
         apply to a pre-existing condition of any Bergen Employee who
         was, as of the Effective Time, excluded from participation in a
         Bergen Benefit Plan by virtue of such pre-existing condition),
         and shall provide that any covered expenses incurred on or
         before the Effective Time by a Bergen Employee or a Bergen
         Employee's covered dependent shall be taken into account for
         purposes of satisfying applicable deductible, coinsurance and
         maximum out-of-pocket provisions after the Effective Time to
         the same extent as such expenses are taken into account for the
         benefit of similarly situated employees of Cardinal and
         subsidiaries of Cardinal.  For purposes of this Section 5.2(l),
         "Bergen Employees" shall mean persons who are, as of the
         Effective Time, employees of Bergen. 

                   5.3  Covenants of Bergen.

                   (a)  Bergen Shareholders Meeting.  Bergen shall take
         all action in accordance with the federal securities laws, the
         NJBCA and the Bergen Certificate and the Bergen Bylaws
         necessary to convene a special meeting of Bergen Shareholders
         (the "Bergen Shareholders Meeting") to be held on the earliest
         practicable date determined by Cardinal, subject to the consent
         of Bergen (which shall not be unreasonably withheld), to
         consider and vote upon approval of the Merger, this Agreement
         and the transactions contemplated hereby.

                   (b)  Information for the Registration Statement and
         Preparation of Joint Proxy Statement.  Bergen shall promptly
         furnish Cardinal with all information concerning it as may be
         required for inclusion in the Registration Statement.  Bergen
         shall cooperate with Cardinal in the preparation of the
         Registration Statement in a timely fashion and shall use all
         reasonable efforts to assist Cardinal in having the
         Registration Statement declared effective by the Commission as
         promptly as practicable consistent with the timing for the
         Cardinal Shareholders Meeting and the Bergen Shareholders
         Meeting as determined by Cardinal, subject to the consent of
         Bergen (which shall not be unreasonably withheld).  If, at any
         time prior to the Effective Time, Bergen obtains knowledge of
         any information pertaining to Bergen that would require any
         amendment or supplement to the Registration Statement or the
         Joint Proxy Statement, Bergen shall so advise Cardinal and
         shall promptly furnish Cardinal with all information as shall
         be required for such amendment or supplement and shall promptly
         amend or supplement the Registration Statement and/or Joint
         Proxy Statement.  Bergen shall use all reasonable efforts to
         cooperate with Cardinal in the preparation and filing of the
         Joint Proxy Statement with the Commission on a confidential
         basis. Consistent with the timing for the Cardinal Shareholders
         Meeting and the Bergen Shareholders Meeting as determined by
         Cardinal, subject to the consent of Bergen (which shall not be
         unreasonably withheld), Bergen shall use all reasonable efforts
         to mail at the earliest practicable date to Bergen Shareholders
         the Joint Proxy Statement, which shall include all information
         required under Applicable Law to be furnished to Bergen
         Shareholders in connection with the Merger and the transactions
         contemplated thereby and shall include the Bergen Board
         Recommendation to the extent not previously withdrawn in
         compliance with Section 5.3(d) and the written opinion of
         Merrill Lynch described in Section 4.23.

                   (c)  Conduct of Bergen's Operations.  Bergen shall
         conduct its operations in the ordinary course except as
         expressly contemplated by this Agreement and the transactions
         contemplated hereby and shall use all reasonable efforts to
         maintain and preserve its business organization and its
         material rights and franchises and to retain the services of
         its officers and key employees and maintain relationships with
         customers, suppliers, lessees, licensees and other third
         parties, and to maintain all of its operating assets in their
         current condition (normal wear and tear excepted), to the end
         that its goodwill and ongoing business shall not be impaired in
         any material respect.  Without limiting the generality of the
         foregoing, during the period from the date of this Agreement to
         the Effective Time, Bergen shall not, except as otherwise
         expressly contemplated by this Agreement and the transactions
         contemplated hereby or as set forth in Section 5.3(c) to the
         Bergen Disclosure Schedule, without the prior written consent
         of Cardinal:

              with respect to its securities:  (A) adjust, split,
              combine or reclassify its capital stock, (B) make, declare
              or pay any dividend (other than regular quarterly
              dividends on Bergen Common Stock of $0.12 per share with
              record and payment dates consistent with past practice) or
              distribution on, or directly or indirectly redeem,
              purchase or otherwise acquire, any shares of its capital
              stock or any securities or obligations convertible into or
              exchangeable for any shares of its capital stock, (C)
              grant any person any right or option to acquire any shares
              of its capital stock, provided, however, that Bergen may
              grant options with a fair market value exercise price to
              purchase up to 1% of the number of shares of Bergen Common
              Stock outstanding as of the date of this Agreement to
              employees of Bergen in the ordinary course consistent with
              prior practice or in connection with acquisitions of
              assets or capital stock permitted pursuant to clause (v)
              below, (D) issue, deliver or sell or agree to issue,
              deliver or sell any additional shares of its capital stock
              or any securities or obligations convertible into or
              exchangeable or exercisable for any shares of its capital
              stock or such securities (except pursuant to the exercise
              of Bergen Options which are outstanding as of the date
              hereof or which are granted by Bergen prior to the
              Effective Time in compliance with the terms of this
              Agreement), or (E) enter into any agreement, understanding
              or arrangement with respect to the sale, voting,
              registration or repurchase of its capital stock;

                       (ii)  directly or indirectly sell, transfer,
              lease, pledge, mortgage, encumber or otherwise dispose of
              any of its property or assets other than in the ordinary
              course of business;

                      (iii)  make or propose any changes in the Bergen
              Certificate or the Bergen Bylaws;

                       (iv)  merge or consolidate with any other person
              (other than as permitted, in each case, by Section
              5.3(d));

                        (v)  acquire for cash a material amount of
              assets or capital stock of any other person valued, giving
              effect to assumed indebtedness, at more than $50 million
              per transaction and $100 million in the aggregate (and, in
              each case, Bergen shall give Cardinal reasonable prior
              notice of any such acquisition or agreement to make such
              an

              acquisition); provided, that to the extent Cardinal
              consents to any such acquisition, such acquisition shall
              not be taken into account in computing the dollar
              limitations in this clause (v); and provided further, that
              Bergen shall not make any acquisition if such acquisition
              would materially and adversely affect the ability of
              Section 6.1(b) to be satisfied on or prior to April 30,
              1998;

                       (vi)  amend or modify, or propose to amend or
              modify, the Bergen Rights Agreement, as amended as of the
              date hereof;

                      (vii)  except pursuant to existing credit
              arrangements, incur, create, assume or otherwise become
              liable for any indebtedness for borrowed money or assume,
              guarantee, endorse or otherwise as an accommodation become
              responsible or liable for the obligations of any other
              individual, corporation or other entity, other than in the
              ordinary course of business, consistent with past practice
              or in connection with a refinancing of existing
              indebtedness (which refinancing shall not increase the
              aggregate amount of indebtedness permitted to be
              outstanding thereunder and shall not include any covenants
              that shall be more burdensome to Bergen in any material
              respect or increase costs to the Surviving Corporation
              after the Effective Time in any material respect);

                     (viii)  create any subsidiaries other than in
              connection with acquisitions of assets or capital stock
              permitted pursuant to clause (v) of this Section 5.3(c);

                       (ix)  enter into or modify any employment,
              severance, termination or similar agreements or
              arrangements with, or grant any bonuses, salary increases,
              severance or termination pay to, any officer, director,
              consultant or employee other than in the ordinary course
              of business consistent with past practice (except for
              change-of-control severance agreements that in all cases
              shall require the prior written consent of Cardinal), or
              otherwise increase the compensation or benefits provided
              to any officer, director, consultant or employee except as
              may be required by Applicable Law or in the ordinary
              course of business consistent with past practice;
              provided, however, that Bergen may implement a stay-bonus
              program providing for bonuses in an aggregate amount,
              together with any severance benefits payable to Bergen
              employees in such program or otherwise, not to exceed
              $13.75 million for employees of Bergen (other than
              employees of Bergen who are in a position of Tier 1 or
              Tier 2) and will consult with, but need not have the
              approval of, Cardinal prior to implementing any such
              plans;

                        (x)  enter into, adopt or amend any employee
              benefit or similar plan except as may be required by
              Applicable Law;

                       (xi)  change any method or principle of
              accounting in a manner that is inconsistent with past
              practice except to the extent required by generally
              accepted accounting principles as advised by Bergen's
              regular independent accountants;

                      (xii)  modify, amend or terminate, or waive,
              release or assign any material rights or claims with
              respect to, any Contract set forth in Section 4.17 to the
              Bergen Disclosure Schedule or any Material Contract other
              than with respect to modifications or

              amendments to, terminations of, waivers or releases under,
              or assignments of (A) Contracts or Material Contracts with
              customers or suppliers entered into in the ordinary course
              of business, (B) Contracts relating to existing
              indebtedness which may be refinanced in compliance with

              incurrence of or commitment to any capital expenditures up
              to $1 million individually or $5 million in the aggregate
              or as set forth in the budget set forth in Section 5.3(c)
              to the Bergen Disclosure Schedule, or (D) without the
              prior written consent of Cardinal (which consent shall not
              be unreasonably withheld) any other material Contract or
              Material Contract to which Bergen is a party or any
              confidentiality agreement to which Bergen is a party;

                     (xiii)  enter into any confidentiality agreements
              or arrangements other than in the ordinary course of
              business consistent with past practice;

              expenditures, individually or in the aggregate, in excess
              of 120% of the amount set forth in Bergen's capital

              excess of 200% of the amount set forth in Section 4.17(k)
              to the Bergen Disclosure Schedule;

                      (xvi)  take any action to exempt or make not
              subject to (x) the provisions of the NJSPA or (y) any
              other state takeover law or state law that purports to
              limit or restrict business combinations or the ability to

              Cardinal or its subsidiaries) or any action taken thereby,

              clauses in this Section 5.3(c);

                      (xix)  permit or cause any subsidiary to do any of

                   (d)  No Solicitation.  Bergen agrees that, during the
         term of this Agreement, it shall not, and shall not authorize

         representatives, directly or indirectly, to solicit, initiate,

         encourage or facilitate, or furnish or disclose non-public
         information in furtherance of, any inquiries or the making of
         any proposal with respect to any recapitalization, merger,
         consolidation or other business combination involving Bergen,
         or acquisition of any capital stock from Bergen (other than
         upon exercise of Bergen Options which are outstanding as of the
         date hereof and other than to the extent specifically permitted
         by Section 5.3(c)(i)) or 15% or more of the assets of Bergen
         and its subsidiaries, taken as a whole, in a single transaction
         or a series of related transactions, or any acquisition by
         Bergen of any material assets or capital stock of any other
         person (other than to the extent specifically permitted by
         Section 5.3(c)(v)), or any combination of the foregoing
         (a "Competing Transaction"), or negotiate, explore or otherwise
         engage in discussions with any person (other than Cardinal,
         Subcorp or their respective directors, officers, employees,
         agents and representatives) with respect to any Competing
         Transaction or enter into any agreement, arrangement or
         understanding requiring it to abandon, terminate or fail to
         consummate the Merger or any other transactions contemplated by
         this Agreement; provided that, at any time prior to the
         approval of the Merger by the Bergen Shareholders, Bergen may
         furnish information to, and negotiate or otherwise engage in
         discussions with, any party who delivers a written proposal for
         a Competing Transaction which was not solicited or encouraged
         after the date of this Agreement if and so long as the Board of
         Directors of Bergen determines in good faith by a majority
         vote, after consultation with and receipt of advice from its
         outside legal counsel, that failing to take such action would
         constitute a breach of the fiduciary duties of the Board of
         Directors of Bergen under Applicable Law and determines that
         such a proposal is, after consulting with Merrill Lynch (or any
         other nationally recognized investment banking firm), more
         favorable to Bergen's Stockholders from a financial point of
         view than the transactions contemplated by this Agreement
         (including any adjustment to the terms and conditions proposed
         by Cardinal in response to such Competing Transaction).  Bergen
         will immediately cease all existing activities, discussions and
         negotiations with any parties conducted heretofore with respect
         to any proposal for a Competing Transaction.  Notwithstanding
         any other provision of this Section 5.2(d), in the event that
         prior to the approval of the Merger by the Bergen Shareholders
         the Board of Directors of Bergen determines in good faith by a
         majority vote, after consultation with and receipt of advice
         from outside legal counsel, that failure to do so would
         constitute a breach of the fiduciary duties of the Bergen Board
         of Directors under Applicable Law, the Board of Directors of
         Bergen may (subject to this and the following sentences)
         withdraw, modify or change, in a manner adverse to Cardinal,
         the Bergen Board Recommendation and, to the extent applicable,
         comply with Rule 14e-2 promulgated under the Exchange Act with
         respect to a Competing Transaction by disclosing such
         withdrawn, modified or changed Bergen Board Recommendation in
         connection with a tender or exchange offer for Bergen
         securities, provided that it uses all reasonable efforts to
         give Cardinal two days prior written notice of its intention to
         do so (provided that the foregoing shall in no way limit or
         otherwise affect Cardinal's right to terminate this Agreement
         pursuant to Section 7.1(d)).  The Bergen Board of Directors
         shall not, in connection with any such withdrawal, modification
         or change of the Bergen Board Recommendation, take any action
         to change the approval of the Board of Directors of Bergen for
         purposes of causing any state takeover statute or other state
         law to be inapplicable to the transactions contemplated hereby,
         including the Merger, the Bergen Stock Option Agreement or the
         Support Agreement.  From and after the execution of this
         Agreement, Bergen shall immediately advise Cardinal in writing
         of the receipt, directly or indirectly, of any inquiries,
         discussions, negotiations, or proposals relating to a Competing


                                    -39-

         Transaction (including the specific terms thereof and the
         identity of the other party or parties involved) and furnish to
         Cardinal within 24 hours of such receipt an accurate
         description of all material terms (including any changes or
         adjustments to such terms as a result of negotiations or
         otherwise) of any such written proposal in addition to any
         information provided to any third party relating thereto.  In
         addition, Bergen shall immediately advise Cardinal, in writing,
         if the Board of Directors of Bergen shall make any
         determination as to any Competing Transaction as contemplated
         by the proviso to the first sentence of this Section 5.3(d).

                   (e)  Termination Right.  If prior to the approval of
         the Merger by the Bergen Shareholders the Board of Directors of
         Bergen shall determine in good faith, after consultation with
         its financial and legal advisors, with respect to any written
         proposal from a third party for a Competing Transaction
         received after the date hereof that was not solicited or
         encouraged by Bergen or any of its subsidiaries or affiliates
         in violation of this Agreement that failure to enter into such
         Competing Transaction would constitute a breach of the
         fiduciary duties of the Board of Directors of Bergen under
         Applicable Law and that such Competing Transaction is more
         favorable to the Bergen Shareholders from a financial point of
         view than the transactions contemplated by this Agreement
         (including any adjustment to the terms and conditions of such
         transaction proposed in writing by Cardinal in response to such
         Competing Transaction) and is in the best interest of the
         Bergen Shareholders and Bergen has received (x) the advice of
         its outside legal counsel as to whether failure to enter into
         such a Competing Transaction would constitute a breach of the
         Board of Directors' fiduciary duties under Applicable Law and
         (y) an opinion (a copy of which, if delivered in writing, has
         been delivered to Cardinal) from Merrill Lynch (or any other
         nationally recognized investment banking firm) that the
         Competing Transaction is more favorable from a financial point
         of view to the Bergen Shareholders than the transactions
         contemplated by this Agreement (including any adjustment to the
         terms and conditions of such transaction proposed in writing by
         Cardinal), Bergen may terminate this Agreement and enter into a
         letter of intent, agreement-in-principle, acquisition agreement
         or other similar agreement (each, an "Acquisition Agreement")
         with respect to such Competing Transaction provided that, prior
         to any such termination, (i) Bergen has provided Cardinal
         written notice that it intends to terminate this Agreement
         pursuant to this Section 5.3(e), identifying the Competing
         Transaction then determined to be more favorable and the
         parties thereto and delivering an accurate description of all
         material terms (including any changes or adjustments to such
         terms as a result of negotiations or otherwise) of the
         Acquisition Agreement to be entered into for such Competing
         Transaction, and (ii) at least three full business days after
         Bergen has provided the notice referred to in clause (i) above
         (provided that the advice and opinion referred to in clauses
         (x) and (y) above shall continue in effect without revocation,
         revision or modification), Bergen delivers to Cardinal (A) a
         written notice of termination of this Agreement pursuant to
         this Section 5.3(e), (B) a check in the amount of Cardinal's
         Costs (as defined in Section 7.2) as the same may have been
         estimated by Cardinal in good faith prior to the date of such
         delivery (subject to an adjustment payment between the parties
         upon Cardinal's definitive determination of such Costs), plus
         the amount of the termination fee as provided in Section 7.2,
         (C) a written acknowledgment from Bergen that (x) the
         termination of this Agreement and the entry into the
         Acquisition Agreement for the Competing Transaction will be a
         "Purchase Event" as defined in the Bergen Stock Option
         Agreement and (y) the Bergen Stock Option Agreement shall be
         honored in accordance with its terms and (D) a written
         acknowledgment from each other party to 


                                    -40-

<PAGE>   45








         such Competing Transaction that it is aware of the substance of
         Bergen's acknowledgment under clause (C) above and waives any
         right it may have to contest the matters thus acknowledged by
         Bergen. 

                   (f)  Affiliates of Bergen.  Bergen shall cause each
         such person who may be at the Effective Time or was on the date
         hereof an "affiliate" of Bergen for purposes of Rule 145 under
         the Securities Act or applicable accounting releases of the
         Commission with respect to pooling of interests accounting
         treatment, to execute and deliver to Cardinal no less than 30
         days prior to the date of the Bergen Shareholders Meeting, the
         written undertakings in the form attached hereto as Exhibit A-1
         (the "Bergen Affiliate Letter").  No later than 45 days prior
         to the date of the Bergen Shareholders Meeting, Bergen, after
         consultation with its outside counsel, shall provide Cardinal
         with a letter (reasonably satisfactory to outside counsel to
         Cardinal) specifying all of the persons or entities who, in
         Bergen's opinion, may be deemed to be "affiliates" of Bergen
         under the preceding sentence.  The foregoing notwithstanding,
         Cardinal shall be entitled to place legends as specified in the
         Bergen Affiliate Letter on the certificates evidencing any of
         the Cardinal Common Shares to be received by (i) any such
         "affiliate" of Bergen specified in such letter or (ii) any
         person Cardinal reasonably identifies (by written notice to
         Bergen) as being a person who may be deemed an "affiliate" for
         purposes of Rule 145 under the Securities Act or applicable
         accounting releases of the Commission with respect to pooling
         of interests accounting treatment, pursuant to the terms of
         this Agreement, and to issue appropriate stop transfer
         instructions to the transfer agent for the Cardinal Common
         Shares, consistent with the terms of the Bergen Affiliate
         Letter, regardless of whether such person has executed the
         Bergen Affiliate Letter and regardless of whether such person's
         name appears on the letter to be delivered pursuant to the
         preceding sentence.

                   (g)  Access.  Bergen shall permit representatives of
         Cardinal to have appropriate access at all reasonable times to
         Bergen's premises, properties, books, records, contracts,
         documents, customers and suppliers. Information obtained by
         Cardinal pursuant to this Section 5.3(g) shall be subject to
         the provisions of the Confidentiality Agreement, which
         agreement remains in full force and effect.  No investigation
         conducted pursuant to this Section 5.3(g) shall affect or be
         deemed to modify any representation or warranty made in this
         Agreement. 

                   (h)  Notification of Certain Matters.  Bergen shall
         give prompt notice to Cardinal of (i) the occurrence or non-
         occurrence of any event the occurrence or non-occurrence of
         which would cause any Bergen representation or warranty
         contained in this Agreement to be untrue or inaccurate at or
         prior to the Effective Time in any material respect and (ii)
         any material failure of Bergen to comply with or satisfy any
         covenant, condition or agreement to be complied with or
         satisfied by it hereunder; provided, however, that the delivery
         of any notice pursuant to this Section 5.3(h) shall not limit
         or otherwise affect the remedies available hereunder to
         Cardinal.

                   (i)  Subsequent Financial Statements.  Bergen shall
         consult with Cardinal prior to making publicly available its
         financial results for any period after the date of this
         Agreement and prior to filing any Bergen SEC Documents after
         the date of this Agreement.

                   (j)  Employee Agreements; Trust Amendment.  Bergen
         shall use its reasonable efforts to cause each of the employees
         of Bergen specified in Section 5.3(j) to the Bergen Disclosure
         Schedule to execute and deliver an Employee Agreement with
         Bergen substantially in the form attached to Section 4.28 to
         the Bergen Disclosure Schedule as soon as possible after the

                   6.2  Conditions to Obligations of Bergen.  The

         transactions contemplated hereby shall be subject to the
         fulfillment of the following conditions unless waived by
         Bergen:

                   (a)  Each of the representations and warranties of
         each of Cardinal and Subcorp set forth in Article III:

                        (i)  which is qualified by materiality or
                   contains references to Material Adverse Effect shall
                   be true and correct in all respects on the date
                   hereof and on and as of the Closing Date as though
                   made on and as of the Closing Date (except for such
                   representations and warranties made as of a specified
                   date, the accuracy of which will be determined as of
                   the specified date); provided, however, that

                             (x)  with respect to any Non-Recurring Non-
                        Attributable Change, the aggregate amount
                        excluded from the determination of whether there
                        has been a Material Adverse Effect on Cardinal
                        from all such Non-Recurring Non-Attributable
                        Changes applied to all of the representations
                        and warranties of Cardinal shall not exceed $30
                        million (without giving effect to any tax
                        consequences), and 

                             (y) solely for purposes of Section
                        7.1(j)(iii) of this Agreement, Attributable
                        Changes with respect to Cardinal may be
                        considered in determining whether there has been
                        any Material Adverse Effect on Cardinal; and

                        (ii)  which is not qualified by materiality and
                   does not contain any reference to Material Adverse
                   Effect shall be true and correct in all material
                   respects on the date hereof and on and as of the
                   Closing Date as though made on


                                    -43-

<PAGE>   48








                   and as of the Closing Date (except for such
                   representations and warranties made as of a specified
                   date, the accuracy of which will be determined as of
                   the specified date).

         The representations and warranties of each of Cardinal and
         Subcorp set forth in Article III shall be true and correct in
         all respects on the date hereof and on and as of the Closing
         Date as though made on and as of the Closing Date (except for
         such representations and warranties made as of a specified
         date, the accuracy of which will be determined as of the
         specified date), except where any such failure of the
         representations and warranties in the aggregate to be true and
         correct in all respects would not have a Material Adverse
         Effect on Cardinal (disregarding, for purposes of this
         provision, the Material Adverse Effect qualification in any
         single representation and warranty); provided, however, that,
         solely for purposes of Section 7.1(j)(iii) of this Agreement,
         Attributable Changes with respect to Cardinal may be considered
         in determining whether there has been any Material Adverse
         Effect on Cardinal.

                   (b)  Each of Cardinal and Subcorp shall have
         performed in all material respects each obligation and
         agreement and shall have complied in all material respects with
         each covenant to be performed and complied with by it hereunder
         at or prior to the Effective Time, except, in all such cases,
         for acts and omissions of Cardinal which, in the aggregate, do
         not have a Material Adverse Effect on Cardinal.

                   (c)  Each of Cardinal and Subcorp shall have
         furnished Bergen with a certificate dated the Closing Date
         signed on behalf of it by the Chairman, President or any Vice
         President to the effect that the conditions set forth in
         Sections 6.2(a) and (b) have been satisfied.

                   (d)  Bergen shall have received the opinion of
         Lowenstein, Sandler, dated on or prior to the effective date of
         the Registration Statement, to the effect that (i) the Merger
         will constitute a reorganization under section 368(a) of the
         Code, (ii) Bergen, Cardinal and Subcorp will each be a party to
         that reorganization, and (iii) no gain or loss will be
         recognized by the shareholders of Bergen upon the receipt of
         Cardinal Common Shares in exchange for shares of Bergen Common
         Stock pursuant to the Merger except with respect to cash
         received in lieu of fractional share interests in Cardinal
         Common Shares.

                   (e)  There shall not be pending any Action which is
         reasonably likely to have a Material Adverse Effect on
         Cardinal.

                   (f)  Since the date of this Agreement, there shall
         not have been any change in the assets, liabilities, results of
         operations or financial condition of Cardinal which would
         constitute a Material Adverse Effect on Cardinal or any event,
         occurrence or development which would have a material adverse
         effect on the ability of Cardinal to consummate the
         transactions contemplated hereby; provided, however, that
         solely for purposes of Section 7.1(j)(iii) of this Agreement,
         Attributable Changes with respect to Cardinal may be considered
         in determining whether there has been any such material adverse
         change that would constitute a Material Adverse Effect on
         Cardinal.

         be subject to the fulfillment of the following conditions

                   contains references to Material Adverse Effect shall
                   be true and correct in all respects on the date
                   hereof and on and as of the Closing Date as though
                   made on and as of the Closing Date (except for such
                   representations and warranties made as of a specified
                   date, the accuracy of which will be determined as of
                   the specified date); provided, however, that

                             (x)  with respect to any Non-Recurring Non-
                        Attributable Change, the aggregate amount
                        excluded from the determination of whether there
                        has been a Material Adverse Effect on Bergen
                        from all such Non-Recurring Non-Attributable
                        Changes applied to all of the representations
                        and warranties of Bergen shall not exceed $30
                        million (without giving effect to any tax
                        consequences), and 

                             (y)  solely for purposes of Section
                        7.1(j)(iii) of this Agreement, Attributable
                        Changes with respect to Bergen may be considered
                        in determining whether there has been any
                        Material Adverse Effect on Bergen; and 

                        (ii)  which is not qualified by materiality and
                   does not contain any reference to Material Adverse
                   Effect shall be true and correct in all material
                   respects on the date hereof and on and as of the
                   Closing Date as though made on and as of the Closing
                   Date (except for such representations and warranties
                   made as of a specified date, the accuracy of which
                   will be determined as of the specified date).

         The representations and warranties of Bergen set forth in
         Article IV shall be true and correct in all respects on the
         date hereof and on and as of the Closing Date as though made on
         and as of the Closing Date (except for such representations and
         warranties made as of a specified date, the accuracy of which
         will be determined as of the specified date), except where any
         such failure of the representations and warranties in the
         aggregate to be true and correct in all respects would not have
         a Material Adverse Effect on Bergen (disregarding, for purposes
         of this provision, the Material Adverse Effect qualification in
         any single representation and warranty); provided, however,
         that, solely for purposes of Section 7.1(j)(iii) of this
         Agreement, Attributable Changes with respect to Bergen may be
         considered in determining whether there has been any Material
         Adverse Effect on Bergen.

                   (b)  Bergen shall have performed in all material
         respects each obligation and agreement and shall have complied
         in all material respects with each covenant to be performed


                                    -45-

         and complied with by it hereunder at or prior to the Effective
         Time, except, in all such cases, for acts and omissions of
         Bergen which, in the aggregate, do not have a Material Adverse
         Effect on Bergen.

                   (c)  Bergen shall have furnished Cardinal with a
         certificate dated the Closing Date signed on its behalf by its
         Chairman, President or any Vice President to the effect that
         the conditions set forth in Sections 6.3(a) and (b) have been
         satisfied.

                   (d)  Since the date of this Agreement, there shall
         not have been any change in the assets, liabilities, results of
         operations or financial condition of Bergen which would
         constitute a Material Adverse Effect on Bergen or any event,
         occurrence or development which would have a material adverse
         effect on the ability of Bergen to consummate the transactions
         contemplated hereby; provided, however, that solely for
         purposes of Section 7.1(j)(iii) of this Agreement, Attributable
         Changes with respect to Bergen may be considered in determining
         whether there has been any such material adverse change that
         would constitute a Material Adverse Effect on Bergen.

                   (e)  There shall not have been a material breach of
         the Bergen Stock Option Agreement.

                   (f)  There shall not be pending any Action which is
         reasonably likely to have a Material Adverse Effect on Bergen.

                   (g)  The Employee Agreements between Bergen and each
         employee of Bergen set forth in Section 4.28 to the Bergen
         Disclosure Schedule, each as in effect as of the date of this
         Agreement, shall be in full force and effect and shall not have
         been terminated; provided, however, that it is understood that
         this condition shall not fail to be satisfied with respect to
         any such person who is no longer employed by Bergen so long as
         Bergen shall not have modified, amended or terminated, granted
         any waiver or release under, or assigned any material rights or
         claims under the Employee Agreement with such former employee
         other than in accordance with its terms.

                            TERMINATION AND AMENDMENT

                   7.1  Termination.  This Agreement may be terminated
         and the Merger may be abandoned at any time prior to the
         Effective Time (notwithstanding any approval of this Agreement
         by Bergen Shareholders and Cardinal Shareholders):

                   (a)  by mutual written consent of Cardinal and
         Bergen;

                   (b)  by either Cardinal or Bergen if there shall be
         any law or regulation that, as supported by written opinion of
         outside legal counsel, makes consummation of the Merger illegal
         or otherwise prohibited, or if any judgment, injunction, order
         or decree of a court or other 


                                    -46-

<PAGE>   51








         competent Governmental Authority enjoining Cardinal or Bergen
         from consummating the Merger shall have been entered and such
         judgment, injunction, order or decree shall have become final
         and nonappealable;

                   (c)  by either Cardinal or Bergen if the Merger shall
         not have been consummated before April 30, 1998, provided,
         however, that the right to terminate this Agreement under this
         Section 7.1(c) shall not be available to any party whose
         failure or whose affiliate's failure to perform any material
         covenant or obligation under this Agreement has been the cause
         of or resulted in the failure of the Merger to occur on or
         before such date;

                   (d)  by Cardinal if the Board of Directors of Bergen
         shall withdraw, modify or change the Bergen Board
         Recommendation in a manner adverse to Cardinal, or if the Board
         of Directors of Bergen shall have refused to affirm the Bergen
         Board Recommendation as promptly as practicable (but in any
         case within 10 business days) after receipt of any written
         request from Cardinal which request was made on a reasonable
         basis;

                   (e)  by Cardinal or Bergen if at the Bergen
         Shareholders Meeting (including any adjournment or postponement
         thereof) the requisite vote of the Bergen Shareholders to
         approve the Merger and the transactions contemplated hereby
         shall not have been obtained; 

                   (f)  by Cardinal or Bergen if the authorization of
         the Cardinal Shareholders with respect to the issuance of
         Cardinal Common Shares in the Merger or the increase in the
         number of authorized Cardinal Common Shares shall not have been
         obtained by reason of the failure to obtain the required vote
         at a meeting held for such purpose;

                   (g)  by Bergen, pursuant to Section 5.3(e);

                   (h)  by Cardinal if Bergen shall have breached in any
         material respect any of its obligations under the Bergen Stock
         Option Agreement or if Mr. Robert E. Martini shall have
         breached in any material respect any of his obligations under
         the Support Agreement with Cardinal; 

                   (i)  by Cardinal if at any time the representations
         and warranties of Bergen set forth in Section 4.15 shall not be
         true and correct and Cardinal shall have been advised by
         Deloitte & Touche LLP that the condition set forth in Section
         6.1(g) cannot be satisfied; 

                   (j)  by Cardinal or Bergen if: 

                             (i)  there shall have been a material
                   breach by the other of any of its representations,
                   warranties, covenants or agreements contained in this
                   Agreement, which breach would result in the failure
                   to satisfy one or more of the conditions set forth in
                   Section 6.2(a) or 6.2(b) (in the case of a breach by
                   Cardinal) or Section 6.3(a) or 6.3(b) (in the case of
                   a breach by Bergen) or would result in a material
                   adverse effect on the ability of Cardinal and/or
                   Bergen to consummate the transactions contemplated
                   hereby, and such breach shall not have been cured

<PAGE>   52








                   within 30 days after notice thereof shall have been
                   received by the party alleged to be in breach; or

                             (ii)  the condition set forth in Section
                   6.3(d) (in the case of a termination by Cardinal) or
                   Section 6.2(f) (in the case of a termination by
                   Bergen) is not satisfied; or

                             (iii)  the condition set forth in Sections
                   6.3(a) or 6.3(d) (in the case of a termination by
                   Cardinal) or Sections 6.2(a) or 6.2(f) (in the case
                   of a termination by Bergen) is not satisfied solely
                   because the proviso regarding Attributable Changes in
                   such section is considered in determining whether any
                   such condition has been satisfied, provided, that the
                   terminating party complies with Section 7.4(c)
                   hereof;

                   (k)  by Bergen if at any time the representations and
         warranties of Cardinal set forth in Section 3.7 shall not be
         true and correct and Cardinal shall have been advised by
         Deloitte & Touche LLP that the condition set forth in Section
         6.1(g) cannot be satisfied; or

                   (l)  by Cardinal or Bergen on one business day's
         prior notice if either party has received any communication
         from the Federal Trade Commission or the Department of Justice
         (each an "HSR Authority") (such communication to be confirmed
         to the other party by the Bureau Director of the Federal Trade
         Commission or such Director's delegate or an Assistant Attorney
         General or the latter's delegate) indicating that an HSR
         Authority has authorized the institution of litigation
         challenging the transactions contemplated by this Agreement
         under the Antitrust Laws, which litigation will include a
         motion seeking an order or injunction prohibiting the
         consummation of any of the transactions contemplated by this
         Agreement; provided, however, that the right to terminate this
         Agreement pursuant to this Section 7.1(l) shall only be
         exercisable within 10 business days after the receipt by either
         party of the first such communication from an HSR Authority.

                   7.2  Effect of Termination.  

                   (a)  In the event of the termination of this
         Agreement pursuant to Section 7.1, this Agreement, except for
         the provisions of the second sentence of each of Section 5.2(g)
         and Section 5.3(g) and the provisions of Sections 7.2 and 8.11,
         shall become void and have no effect, without any liability on
         the part of any party or its directors, officers or
         stockholders.  Notwithstanding the foregoing, nothing in this
         Section 7.2 shall relieve any party to this Agreement of
         liability for a material breach of any provision of this
         Agreement and provided, further, however, that if it shall be
         judicially determined that termination of this Agreement was
         caused by an intentional breach of this  Agreement, then, in
         addition to other remedies at law or equity for breach of this
         Agreement, the party so found to have intentionally breached
         this Agreement shall indemnify and hold harmless the other
         parties for their respective out-of-pocket costs, fees and
         expenses of their counsel, accountants, financial advisors and
         other experts and advisors as well as fees and expenses
         incident to negotiation, preparation and execution of this
         Agreement and related documentation and shareholders' meetings
         and consents ("Costs").

                   (b)  Bergen agrees that, if:

                        (i)  Bergen terminates this Agreement pursuant
                   to Sections 5.3(e) and 7.1(g);

                        (ii)  Cardinal terminates this Agreement
                   pursuant to Section 7.1(d) or 7.1(h); or

                        (iii) (A) Cardinal or Bergen terminates this
                   Agreement pursuant to Section 7.1(e), (B) at the time
                   of such failure by Bergen Shareholders to so approve
                   this Agreement there is a publicly announced or
                   disclosed Competing Transaction with respect to
                   Bergen involving a third party, and (C) within 12
                   months after such termination, Bergen shall enter
                   into an Acquisition Agreement for a Business
                   Combination (as defined herein) or consummates a
                   Business Combination; 

         then, (X) in the case of a termination by Cardinal, within
         three business days following any such termination, (Y) in the
         case of a termination by Bergen as described in clause (i)
         above, concurrently with such termination, or (Z) in the case
         of a termination by Bergen as described in clause (iii) above
         where a Competing Transaction has been publicly announced or
         publicly disclosed prior to the Bergen Shareholders Meeting
         (including any adjournment or postponement thereof), prior to
         the earlier consummation of a Business Combination or execution
         of a definitive agreement with respect thereto, Bergen will pay
         to Cardinal in cash by wire transfer in immediately available
         funds to an account designated by Cardinal (i) in reimbursement
         for Cardinal's expenses an amount in cash equal to the
         aggregate amount of Cardinal's Costs incurred in connection
         with pursuing the transactions contemplated by this Agreement,
         including, without limitation, legal, accounting and investment
         banking fees, up to but not in excess of an amount equal to $12
         million in the aggregate and (ii) a termination fee in an
         amount equal to $75 million (such amounts collectively, the
         "Termination Fee").  For the purposes of this Section 7.2,
         "Business Combination" means (i) a merger, consolidation, share
         exchange, business combination or similar transaction involving
         Bergen as a result of which the Bergen Shareholders prior to
         such transaction in the aggregate cease to own at least 85% of
         the voting securities of the entity surviving or resulting from
         such transaction (or the ultimate parent entity thereof), (ii)
         a sale, lease, exchange, transfer or other disposition of more
         than 15% of the assets of Bergen and its subsidiaries, taken as
         a whole, in a single transaction or a series of related
         transactions, or (iii) the acquisition, by a person (other than
         Cardinal or any affiliate thereof) or group (as such term is
         defined under Section 13(d) of the Exchange Act and the rules
         and regulations thereunder) of beneficial ownership (as defined
         in Rule 13d-3 under the Exchange Act) of more than 15% of the
         Bergen Common Stock whether by tender or exchange offer or
         otherwise. 

                   7.3  Amendment.  This Agreement may be amended by the
         parties hereto, by action taken or authorized by their
         respective Boards of Directors, at any time before or after
         adoption of this Agreement by Bergen Shareholders, but after
         any such approval, no amendment shall be made which by law
         requires further approval or authorization by the Bergen 


                                    -49-

<PAGE>   54








         Shareholders without such further approval or authorization.
         Notwithstanding the foregoing, this Agreement may not be
         amended except by an instrument in writing signed on behalf of
         each of the parties hereto.

                   7.4  Liquidated Damages.   

                   (a)  In the event that the Board of Directors of
         Cardinal shall withdraw or change in a manner adverse to Bergen
         its recommendation as set forth in Section 3.12 of this
         Agreement, and this Agreement shall have terminated in
         accordance with the terms hereof as a result thereof, then
         within 3 days after delivery of notice of such termination by
         Bergen to Cardinal, Cardinal shall pay to Bergen in cash by
         wire transfer of immediately available funds to an account
         designated by Bergen, as liquidated damages (i) in
         reimbursement for Bergen's expenses, an amount of cash equal to
         the aggregate amount of Bergen's Costs up to but not equal to
         $12 million in the aggregate and (ii) the amount of $75
         million.

                   (b)  In the event that this Agreement is terminated
         by Cardinal or Bergen (the "Terminating Party") pursuant to
         Section 7.1(j) hereof as a result of the failure of the other
         party or its affiliates (the "Breaching Party") to perform its
         material covenants and obligations under Section 5.1(a)(i) or
         5.1(a)(ii) hereof, then within 3 days after such termination,
         the Breaching Party shall pay to the Terminating Party in cash
         by wire transfer of immediately available funds to an account
         designated by the Terminating Party, as liquidated damages, an
         amount of cash equal to $50 million.

                   (c)  In the event that this Agreement is terminated
         by Cardinal or Bergen pursuant to Section 7.1(j)(iii) as a
         result, in whole or in part, of an Attributable Change with
         respect to the other party, then contemporaneously with such
         termination, the terminating party shall pay in cash by wire
         transfer of immediately available funds to an account
         designated by the other party as liquidated damages the amount
         of $75 million.

                   7.5  Exclusive Remedy.  In the event that any
         Termination Fee is paid pursuant to Section 7.2 or any
         liquidated damages are paid pursuant to Section 7.4,
         notwithstanding any other provision of this Agreement, it is
         understood and agreed that such Termination Fee or liquidated
         damages, as the case may be, shall be the exclusive remedy for
         any act or omission resulting in the termination of this
         Agreement or other claim arising out of this Agreement or the
         transactions contemplated hereby.

                   7.6  Extension; Waiver.  At any time prior to the
         Effective Time, Cardinal (with respect to Bergen) and Bergen
         (with respect to Cardinal and Subcorp) by action taken or
         authorized by their respective Boards of Directors, may, to the
         extent legally allowed, (a) extend the time for the performance
         of any of the obligations or other acts of such party, (b)
         waive any inaccuracies in the representations and warranties
         contained herein or in any document delivered pursuant hereto
         and (c) waive compliance with any of the agreements or
         conditions contained herein.  Any agreement on the part of a
         party hereto to any such extension or waiver shall be valid
         only if set forth in a written instrument signed on behalf of
         such party.

         effect on the assets (including intangible assets), liabilities
         (contingent or otherwise), results of operations or financial
         condition of such party and its subsidiaries taken as a whole;
         provided, however, that a Material Adverse Effect with respect
         to any party shall not include:

                        (i)  any change in or effect upon the assets
                   (including intangible assets), liabilities
                   (contingent or otherwise), financial condition, or

                   subsidiaries directly or indirectly arising out of or
                   attributable to any decrease in the market price of
                   Cardinal Common Shares in the case of Cardinal or
                   Bergen Common Stock in the case of Bergen (but in
                   either case not any change or effect underlying such
                   decrease to the extent such change or effect would
                   otherwise constitute a Material Adverse Effect on
                   such party), 

                        (ii)  any change in or effect upon the assets
                   (including intangible assets), liabilities
                   (contingent or otherwise), financial condition, or

                   subsidiaries directly or indirectly arising out of or
                   attributable to conditions, events, or circumstances
                   generally affecting the industries in which Cardinal
                   (and its subsidiaries) and Bergen (and its

                   Changes in determining whether the conditions set
                   forth in Sections 6.3(d) or 6.2(f) have been
                   satisfied, and (B) in considering the accuracy of an
                   individual representation and warranty, such $30
                   million may be allocated among the various
                   representations and warranties so long as the
                   aggregate amount does not exceed $30 million
                   (determined without giving effect to any tax
                   consequences), or

                              STOCK OPTION AGREEMENT


                   STOCK OPTION AGREEMENT ("Option Agreement") dated
         August 23, 1997, between Cardinal Health, Inc., an Ohio
         corporation ("Cardinal"), and Bergen Brunswig Corporation, a
         New Jersey corporation ("Bergen").


                               W I T N E S S E T H:

                   WHEREAS, the Board of Directors of Cardinal and the
         Board of Directors of Bergen have approved an Agreement and
         Plan of Merger dated as of even date herewith (the "Merger
         Agreement") providing for the merger of a wholly owned
         subsidiary of Cardinal with and into Bergen;

                   WHEREAS, as a condition to Cardinal's entering into
         the Merger Agreement, Cardinal has required that Bergen agree,
         and Bergen has agreed, to grant to Cardinal the option set
         forth herein to purchase authorized but unissued shares of
         Bergen Common Stock;

                   NOW, THEREFORE, in consideration of the premises
         herein contained, the parties agree as follows:



         1.  Definitions.

                   Capitalized terms used but not defined herein shall
         have the same meanings as in the Merger Agreement.  

         2.  Grant of Option.

                   Subject to the terms and conditions set forth herein,
         Bergen hereby grants to Cardinal an option (the "Option") to
         purchase up to 10,028,163 authorized and unissued shares of
         Bergen Common Stock (the "Option Shares") at a price per share
         equal to $48.29 (the "Purchase Price") payable in cash as
         provided in Section 4 hereof.

         3.  Exercise of Option.

         (a)  Cardinal may exercise the Option, in whole or in part, at
         any time or from time to time if a Purchase Event (as defined
         below) shall have occurred and the Merger Agreement shall have
         been terminated; provided, however, that to the extent the
         Option shall not have been exercised, it shall terminate and be
         of no further force and effect upon the earliest to occur of:

                   (i)  the Effective Time of the Merger,

                   (ii)  5:00 p.m. New York City time, on the date which
              is 180 days following the occurrence of a Purchase Event
              and 

                   (iii)  (x) the termination of the Merger Agreement in
              accordance with its terms (other than (A) pursuant to
              Section 7.1(g) thereof or (B) pursuant to Section 7.1(e)
              thereof if at the Bergen Shareholders Meeting (including
              any adjournment or postponement thereof) the requisite
              vote of the Bergen Shareholders to approve the Merger and
              the transactions contemplated hereby shall not have been
              obtained, and at the time of such failure by Bergen
              Shareholders to so approve the Merger there is a publicly
              announced or disclosed Competing Transaction with respect
              to Bergen) prior to the occurrence of a Purchase Event, or
              (y)  5:00 p.m. New York City time, on the date which is
              one year following the termination of the Merger Agreement
              pursuant to Section 7.1(e) thereof if no Purchase Event
              has occurred pursuant to clause (b)(ii) below; 

         and provided, further, that if the Option cannot be exercised
         before its date of termination as a result of any injunction,
         order or similar restraint issued by a court of competent
         jurisdiction, the Option shall expire on the 10th business day
         after such injunction, order or restraint shall have been
         dissolved or when such injunction, order or restraint shall
         have become permanent and no longer subject to appeal, as the
         case may be but in no event later than 18 months after the
         occurrence of a Purchase Event.

         (b)  As used herein, a "Purchase Event" shall mean any of the
         following events:

                   (i)  the Board of Directors of Bergen shall have
              withdrawn, modified or changed the Bergen Board
              Recommendation in a manner adverse to Cardinal, or if the
              Board of Directors of Bergen shall have refused to affirm
              the Bergen Board Recommendation as promptly as practicable
              (but in any case within 10 business days) after receipt of
              any written request from Cardinal which request was made
              on a reasonable basis;

                   (ii)  if at the Bergen Shareholders Meeting
              (including any adjournment or postponement thereof) the
              requisite vote of the Bergen Shareholders to approve the
              Merger and the transactions contemplated hereby shall not
              have been obtained, and at the time of such failure by
              Bergen Shareholders to so approve the Merger there is a
              publicly announced or disclosed Competing Transaction with
              respect to Bergen involving a third party and within
              twelve months after termination of the Merger Agreement,
              Bergen shall enter into a letter of intent, agreement-in-
              principle, business combination or merger agreement or
              other similar agreement for a Competing Transaction or a
              Competing Transaction is consummated in each case with
              such third party or a national or international wholesale
              pharmaceutical distributor or any of their respective
              affiliates;

                   (iii)  if Bergen shall have breached in any material
              respect any of its obligations under this Agreement; or

                   (iv)  the Merger Agreement shall have been terminated
              by Bergen pursuant to Sections 5.3(e) and 7.1(g) of the
              Merger Agreement.

         (c)  As used herein, the terms "Beneficial Ownership",
         "Beneficial Owner" and "Beneficially Own" shall have the
         meanings ascribed to them in Rule 13d-3 under the Exchange Act.
         As used herein, "person" shall have the meaning specified in
         Sections 3(a)(9) and 13(d)(3) of the Exchange Act.

         (d)  In the event Cardinal wishes to exercise the Option, it
         shall deliver to Bergen a written notice (the date of receipt
         of which being herein referred to as the "Notice Date")
         specifying (i) the total number of shares it intends to
         purchase pursuant to such exercise and (ii) a place and date
         not earlier than two business days nor later than 60 calendar
         days from the Notice Date for the closing of such purchase (the
         "Closing Date"); provided that if the closing of the purchase
         and sale pursuant to the Option (the "Closing") cannot be
         consummated by reason of any applicable judgment, decree,
         order, law or regulation, the period of time that otherwise
         would run pursuant to this sentence shall run instead from the
         date on which such restriction on consummation has expired or
         been terminated; and, provided further that, without limiting
         the foregoing, if prior notification to or approval of any
         regulatory authority is required in connection with such
         purchase, Cardinal and, if applicable, Bergen shall promptly
         file the required notice or application for approval and shall
         expeditiously process the same (and Bergen shall cooperate with
         Cardinal in the filing of any such notice or application and
         the obtaining of any such approval), and the period of time
         that otherwise would run pursuant to this sentence shall run
         instead from the date on which, as the case may be, (i) any
         required notification period has expired or been terminated or
         (ii) such approval has been obtained, and in either event, any
         requisite waiting period has passed.

         (e)  In the event (i) Cardinal receives official notice that an
         approval of any regulatory authority required for the purchase
         of Option Shares would not be issued or granted or (ii) a
         Closing Date shall not have occurred within 18 months after the
         related Notice Date due to the failure to obtain any such
         required approval, Cardinal shall be entitled to exercise its
         right as set forth in Section 7 or, to the extent legally
         permitted, to exercise the Option in connection with the resale
         of Bergen Common Stock or other securities pursuant to a
         registration statement as provided in Section 9.  The
         provisions of this Section 3 and Section 6 shall apply with
         appropriate adjustments to any such exercise.

         4.  Payment and Delivery of Certificates.

         (a)  At the closing, referred to in Section 3 hereof, on the
         Closing Date, Cardinal shall pay to Bergen the aggregate
         Purchase Price for the shares of Bergen Common Stock purchased
         pursuant to the exercise of the Option in immediately available
         funds by wire transfer to a bank account designated not later
         than one business day prior to the Closing Date by Bergen.

         (b)  At such closing, simultaneously with the delivery of cash
         as provided in Section 4(a), Bergen shall deliver to Cardinal a
         certificate or certificates representing the number of shares
         of Bergen Common Stock purchased by Cardinal, registered in the
         name of Cardinal or a nominee designated in writing by
         Cardinal, which shares shall be fully paid and non-assessable
         and free and clear of all liens, claims, charges and
         encumbrances of any kind whatsoever.


                                     -3-

         (c)  If at the time of issuance of any Bergen Common Stock
         pursuant to any exercise of the Option, Bergen shall have
         issued any share purchase rights or similar securities to
         holders of Bergen Common Stock, then each such share of Bergen
         Common Stock shall also represent rights with terms
         substantially the same as and at least as favorable to Cardinal
         as those issued to other holders of Bergen Common Stock.

         (d)  Certificates for Bergen Common Stock delivered at any
         closing hereunder shall be endorsed with a restrictive legend
         which shall read substantially as follows:

                   "The shares represented by this certificate are
                   subject to certain provisions of an agreement between
                   the registered holder hereof and Bergen Brunswig
                   Corporation, a copy of which is on file at the
                   principal office of Bergen Brunswig Corporation, and
                   to resale restrictions arising under the Securities
                   Act of 1933, as amended, and any applicable state
                   securities laws.  A copy of such agreement will be
                   provided to the holder hereof without charge upon
                   receipt by Bergen Brunswig Corporation of a written
                   request therefor."

         It is understood and agreed that the above legend shall be
         removed by delivery of substitute certificate(s) without such
         legend in connection with a transfer or sale if (i) Bergen has
         been furnished with an opinion of counsel, reasonably
         satisfactory to counsel for Bergen, that such transfer or sale
         will not violate the Securities Act or applicable securities
         laws of any state or (ii) such transfer or sale shall have been
         registered and qualified pursuant to the Securities Act and any
         applicable state securities laws.

         5.  Authorization, etc.

         (a)  Bergen hereby represents and warrants to Cardinal that: 

                   (i)  Bergen has full corporate authority to execute
              and deliver this Option Agreement and to consummate the
              transactions contemplated hereby;

                   (ii)  such execution, delivery and consummation have
              been authorized by the Board of Directors of Bergen, and
              no other corporate proceedings are necessary therefor; 

                   (iii)  this Option Agreement has been duly and
              validly executed and delivered by Bergen and represents a
              valid and legally binding obligation of Bergen,
              enforceable against Bergen in accordance with its terms;

                   (iv)  Bergen has taken all necessary corporate action
              to authorize and reserve and permit it to issue and, at
              all times from the date hereof through the date of the
              exercise in full or the expiration or termination of the
              Option, shall have reserved for issuance upon exercise of
              the Option, 10,028,163 shares of Bergen Common Stock
              (subject to adjustment as provided herein), all of which,
              upon issuance in accordance with the terms of this Option
              Agreement, shall be duly authorized, validly issued, fully
              paid and nonassessable, and shall be delivered free and
              clear of all claims, liens, encumbrances


                                     -4-

              and security interests and not subject to any preemptive
              rights of any shareholder of Bergen; and  

                   (v)  The Bergen Rights Agreement has been amended,
              and will remain amended (and no replacement plan will be
              adopted), so as to provide that none of Cardinal and its
              affiliates will become an "Acquiring Person" and that no
              "Stock Acquisition Date" or "Distribution Date" (as such
              terms are defined in the Rights Agreement) will occur as a
              result of the execution of this Option Agreement, the
              grant of the Option hereunder or the acquisition or
              transfer of shares of Bergen Common Stock by Cardinal
              pursuant to the exercise, in whole or in part, of the
              Option. 

         (b)  Bergen hereby agrees that, prior to the termination of the
         Option pursuant to Section 3(a) hereof, Bergen shall not take,
         or allow to be taken, any action that could result in the
         representations and warranties set forth in Section 5(a)(v)
         hereof becoming false or inaccurate.

         (c)  Cardinal hereby represents and warrants to Bergen that:  

                   (i)  Cardinal has full corporate authority to execute
              and deliver this Option Agreement and to consummate the
              transactions contemplated hereby; 

                   (ii)  such execution, delivery and consummation have
              been authorized by all requisite corporate action by
              Cardinal, and no other corporate proceedings are necessary
              therefor; 

                   (iii)  this Option Agreement has been duly and
              validly executed and delivered by Cardinal and represents
              a valid and legally binding obligation of Cardinal,
              enforceable against Cardinal in accordance with its terms;
              and

                   (iv)  any Bergen Common Stock acquired by Cardinal
              upon exercise of the Option will be acquired for its own
              account and not be taken with a view to the public
              distribution thereof and will not be transferred or
              otherwise disposed of except in compliance with the
              Securities Act.

         6.  Adjustment upon Changes in Capitalization.

                   In the event of any change in Bergen Common Stock by
         reason of stock dividends, split-ups, recapitalizations or the
         like, the type and number of shares subject to the Option, and
         the purchase price per share, as the case may be, shall be
         adjusted appropriately.  In the event that any additional
         shares of Bergen Common Stock are issued after the date of this
         Option Agreement (other than pursuant to an event described in
         the preceding sentence or pursuant to this Option Agreement or
         options granted under employee benefit plans), the number of
         shares of Bergen Common Stock subject to the Option shall be
         adjusted so that, after such issuance, it equals at least 19.9%
         of the number of shares of Bergen Common Stock then issued and
         outstanding (without considering any shares subject to or
         issued pursuant to the Option).

         7.  Repurchase.

         (a)  At the request of Cardinal, at any time from and after the
         occurrence of a Purchase Event and ending 180 days immediately
         thereafter (the "Cardinal Repurchase Period"), Bergen (or any
         successor entity thereof) shall repurchase the Option from
         Cardinal together with all (but not less than all) shares of
         Bergen Common Stock purchased by Cardinal pursuant thereto with
         respect to which Cardinal then has Beneficial Ownership, at a
         price (when calculated on a per share basis, the "Per Share
         Repurchase Price") equal to the sum of:

                   (i)  The difference between (A) the "Market/Tender
              Offer Price" for shares of Bergen Common Stock (defined as
              the higher of (x) the highest price per share at which a
              tender or exchange offer has been made for shares of
              Bergen Common Stock or (y) the highest closing price per
              share of Bergen Common Stock as reported by the NYSE
              Composite Tape for any day within that portion of the
              Cardinal Repurchase Period which precedes the date
              Cardinal gives notice of the required repurchase under
              this Section 7) and (B) the Purchase Price (subject to
              adjustment as provided in Section 6), multiplied by the
              number of shares of Bergen Common Stock with respect to
              which the Option has not been exercised, but only if such
              Market/Tender Offer Price is greater than such exercise
              price;

                   (ii)  The exercise price paid by Cardinal for any
              shares of Bergen Common Stock acquired pursuant to the
              Option; and

                   (iii)  The difference between the Market/Tender Offer
              Price and the exercise price paid by Cardinal for any
              shares of Bergen Common Stock purchased pursuant to the
              exercise of the Option, multiplied by the number of shares
              so purchased, but only if such Market/Tender Offer Price
              is greater than such exercise price.

         (b)  In the event Cardinal exercises its rights under this
         Section 7, Bergen shall, within 10 business days thereafter,
         pay the required amount to Cardinal by wire transfer of
         immediately available funds to an account designated by
         Cardinal and Cardinal shall surrender to Bergen the Option and
         the certificates evidencing the shares of Bergen Common Stock
         purchased thereunder with respect to which Cardinal then has
         Beneficial Ownership.  

         (c)  In determining the Market/Tender Offer Price, the value of
         any consideration other than cash shall be determined by an
         independent nationally recognized investment banking firm
         selected by Cardinal. 

         8.  Repurchase at Option of Bergen.

                   Except to the extent that Cardinal shall have
         previously exercised its rights under Section 7, at the request
         of Bergen during the six-month period commencing 180 days
         following the first occurrence of a Purchase Event, Bergen may
         repurchase from Cardinal, and Cardinal shall sell to Bergen,
         all (but not less than all) of the Bergen Common Stock acquired
         by Cardinal pursuant to the Option and with respect to which
         Cardinal has Beneficial Ownership at the time


                                     -6-

<PAGE>   7






         of such repurchase at a price per share equal to the greater of
         (i) 110% of the Market/Tender Offer Price per share (calculated
         in the manner set forth in Section 7(a)(i) hereof but utilizing
         the period beginning on the occurrence of a Purchase Event and
         ending on the date Bergen exercises its repurchase right
         pursuant to this Section 8), (ii) the Per Share Repurchase
         Price or (iii) the sum of (A) the aggregate Purchase Price of
         the shares so repurchased plus (B) interest on the aggregate
         Purchase Price paid for the shares so repurchased from the date
         of purchase by Cardinal to the date of repurchase at the
         highest rate of interest announced by Bank One, Columbus, NA as
         its prime or base lending or reference rate during such period,
         less any dividends received on the shares so repurchased, which
         sum shall be divided by the number of shares of Bergen Common
         Stock to be repurchased by Bergen.  Any repurchase under this
         Section 8 shall be consummated in accordance with Section 7(b).

         9.  Registration Rights.

                   At any time after a Closing, Bergen shall, if
         requested by any holder or Beneficial Owner of shares of Bergen
         Common Stock issued upon exercise of the Option (each a
         "Holder"), as expeditiously as possible file a registration
         statement on a form for general use under the Securities Act if
         necessary in order to permit the sale or other disposition of
         the shares of Bergen Common Stock that have been acquired upon
         exercise of the Option in accordance with the intended method
         of sale or other disposition requested by any such Holder.
         Each such Holder shall provide all information reasonably
         requested by Bergen for inclusion in any registration statement
         to be filed hereunder.  Bergen shall use its best efforts to
         cause such registration statement first to become effective and
         then to remain effective for such period not in excess of 180
         days from the day such registration statement first becomes
         effective as may be reasonably necessary to effect such sales
         or other dispositions.  The registration effected under this
         Section 9 shall be at Bergen's expense except for underwriting
         commissions and the fees and disbursements of such Holders'
         counsel attributable to the registration of such Bergen Common
         Stock.  In no event shall Bergen be required to effect more
         than one registration hereunder.  The filing of any
         registration statement required hereunder may be delayed for
         such period of time (not to exceed 90 days) as may reasonably
         be required to facilitate any public distribution by Bergen of
         Bergen Common Stock, if a special audit of Bergen would
         otherwise be required in connection therewith during which
         Bergen is in possession of material information concerning it,
         its business affairs or a material transaction in each case the
         public disclosure of which could have a material adverse effect
         on Bergen or significantly disrupt such material transaction.
         If requested by any such Holder in connection with such
         registration, Bergen shall become a party to any underwriting
         agreement relating to the sale of such shares on terms and
         including obligations and indemnities which are customary for
         parties similarly situated.  Upon receiving any request for
         registration under this Section 9 from any Holder, Bergen
         agrees to send a copy thereof to any other person known to
         Bergen to be entitled to registration rights under this Section
         9, in each case by promptly mailing the same, postage prepaid,
         to the address of record of the persons entitled to receive
         such copies.

         10.  Listing.

                   If Bergen Common Stock or any other securities to be
         acquired upon exercise of the Option are then listed on the
         NYSE or any other national securities exchange, Bergen, upon
         the request of Cardinal, will promptly file an application to
         list the shares of Bergen Common Stock or other securities to
         be acquired upon exercise of the Option on the NYSE or such
         other exchange and will use its best efforts to obtain approval
         of such listings as soon as practicable.

         11.  Severability.

                   Any term, provision, covenant or restriction
         contained in this Option Agreement held by a court or other
         Governmental Authority of competent jurisdiction to be invalid,
         void or unenforceable, shall be ineffective to the extent of
         such invalidity, voidness or unenforceability, but neither the
         remaining terms, provisions, covenants or restrictions
         contained in this Option Agreement nor the validity or
         enforceability thereof in any other jurisdiction shall be
         affected or impaired thereby.  Any term, provision, covenant or
         restriction contained in this Option Agreement that is so found
         to be so broad as to be unenforceable shall be interpreted to
         be as broad as is enforceable.  

         12.  Miscellaneous.

         (a)  Expenses.  Each of the parties hereto shall pay all costs
         and expenses incurred by it or on its behalf in connection with
         the transactions contemplated hereunder, including fees and
         expenses of its own financial consultants, investment bankers,
         accountants and counsel, except as otherwise provided herein.

         (b)  Entire Agreement.  This Option Agreement, the Support
         Agreements, the Merger Agreement (including the documents and
         the instruments referred to therein) and the Confidentiality
         Agreement constitute the entire agreement among the parties and

         Agreement, expressed or implied, is intended to confer upon any
         party, other than the parties hereto, and their respective
         successors and assigns, any rights, remedies, obligations, or

         an original instrument, but both such counterparts together
         shall constitute but one agreement.

         (f)  Further Assurances.  In the event of any exercise of the
         Option by Cardinal, Bergen and Cardinal shall execute and
         deliver all other documents and instruments and take all other
         action that may be reasonably necessary in order to consummate
         the transactions provided for by such exercise.

         (g)  Specific Performance.  The parties hereto agree that if
         for any reason Cardinal or Bergen shall have failed to perform

         hereto seeking to enforce this Option Agreement against such
         non-performing party shall be entitled to specific performance
         and injunctive and other equitable relief, and the parties
         hereto further agree to waive any requirement for the securing
         or posting of any bond in connection with the obtaining of any

         without prejudice to any other rights that either party hereto

         (h)  Governing Law.  Except to the extent that the laws of the
         jurisdiction of organization of any party hereto, or any other
         jurisdiction, are mandatorily applicable to matters arising

         Agreement shall be governed by the laws of the State of New
         York.  All actions and proceedings arising out of or relating
         to this Option Agreement shall be heard and determined in any

              York and to the jurisdiction of the United States District
              Court for the Southern District of New York, for the
              purpose of any action or proceeding arising out of or
              relating to this Option Agreement and each of the parties
              hereto irrevocably agrees that all claims in respect to
              such action or proceeding may be heard and determined
              exclusively in any New York state or federal court sitting
              in the City of New York.  Each of the parties hereto
              agrees that a final judgment in any action or proceeding
              shall be conclusive and may be enforced in other
              jurisdictions by suit on the judgment or in any other
              manner provided by law.

                   (ii)  Each of the parties hereto irrevocably consents
              to the service of any summons and complaint and any other

              delivery of copies of such process to such party.  Nothing
              in this Section 11(i) shall affect the right of any party
              hereto to serve legal process in any other manner
              permitted by law.

         (j)  Regulatory Approvals; Section 16(b).  If, in connection
         with the exercise of the Option under Section 3, prior
         notification to or approval of any Governmental Authority is
         required, then the required notice or application for approval
         shall be promptly filed and/or expeditiously processed by
         Bergen and periods of time that otherwise would run pursuant
         hereto (if any) shall run instead from the date on which any
         such required notification period has expired or been

         terminated or such approval has been obtained, and in either
         event, any requisite waiting period shall have passed.  Periods
         of time that otherwise would run pursuant to Sections 3, 7 or 8
         shall also be extended to the extent necessary to avoid
         liability under Section 16(b) of the Exchange Act.

         (k)  Waiver and Amendment.  Any provision of this Option
         Agreement may be waived at any time by the party that is

         Cardinal Health, Inc.
         5555 Glendon Court
         Dublin, Ohio  43016

                   Re:  Support/Voting Agreement
                        ------------------------
         Dear Sirs:

                   The undersigned understands that Cardinal Health,
         Inc. ("Cardinal"), Bruin Merger Corp., a wholly owned
         subsidiary of Cardinal ("Subcorp"), and Bergen Brunswig
         Corporation ("Bergen") are entering into an Agreement and Plan
         of Merger, dated the date hereof (the "Agreement"), providing
         for, among other things, a merger between Subcorp and Bergen
         (the "Merger"), in which all of the outstanding shares of
         capital stock of Bergen will be exchanged for common shares,
         without par value, of Cardinal.

                   The undersigned is a shareholder of Bergen (the
         "Shareholder") and is entering into this letter agreement to
         induce you to enter into the Agreement and to consummate the
         transactions contemplated thereby.

                   The Shareholder confirms its agreement with you as
         follows:

                   1.   The Shareholder represents, warrants and agrees
         that Schedule I annexed hereto sets forth the shares of the
         capital stock of Bergen of which the Shareholder is the record
         or beneficial owner (the "Shares") and that the Shareholder is
         on the date hereof the lawful owner of the number of Shares set
         forth in Schedule I, free and clear of all liens, charges,
         encumbrances, voting agreements and commitments of every kind,
         except as disclosed previously in writing to Cardinal.  Except
         for the Shares set forth in Schedule I, the Shareholder does
         not own or hold any rights to acquire any additional shares of
         the capital stock of Bergen (other than pursuant to stock
         options) or any interest therein or any voting rights with
         respect to any additional shares.  

                   2.   The Shareholder agrees that it will not, will
         not permit any company, trust or other entity controlled by the
         Shareholder to contract to sell, sell or otherwise transfer or
         dispose of any of the Shares or any interest therein or
         securities convertible thereinto or any voting rights with
         respect thereto, other than (i) pursuant to the Merger, (ii)
         with your prior written consent or (iii) to the extent
         contractually required (as disclosed previously in writing to
         Cardinal).

                   3.   The Shareholder agrees to, will cause any
         company, trust or other entity controlled by the Shareholder
         to, and will use its reasonable best efforts to cause its
         affiliates (as defined under the Securities Exchange Act of
         1934, as amended) to, cooperate fully with you in connection
         with the Agreement and the transactions contemplated thereby.
         The Shareholder agrees that, during the term of this letter
         agreement, it will not, and will not permit any such company,
         trust or other entity to, and will use its reasonable best
         efforts to not permit any of its affiliates to, directly or
         indirectly (including through its directors, officers,
         employees or other representatives) solicit, initiate,
         encourage or facilitate, or furnish or disclose non-public
         information in furtherance of, any inquiries or the making of
         any proposal with respect to any Competing Transaction, or
         negotiate, explore or otherwise engage in discussions with any
         person (other than Cardinal, Subcorp or their respective
         directors, officers, employees, agents and representatives)
         with respect to any Competing Transaction or enter into any
         agreement, arrangement or understanding with respect to any
         Competing Transaction or agree to or otherwise assist in the
         effectuation of any Competing Transaction; provided, however,
         that nothing herein shall prevent the Shareholder from taking
         any action, after having notified Cardinal thereof, or omitting
         to take any action solely as a member of the Board of Directors
         of Bergen required so as not to violate such Shareholder's
         fiduciary obligations as a Director after consultation with
         outside counsel.  

                   4.   The Shareholder agrees that all of the Shares
         beneficially owned by the Shareholder (except shares subject to
         unexercised stock options), or over which the Shareholder has
         voting power or control, directly or indirectly (including any
         common shares of Bergen acquired after the date hereof), at the
         record date for any meeting of shareholders of Bergen called to
         consider and vote to approve the Merger and the Agreement and/
         or the transactions contemplated thereby and/or any Competing
         Transaction will be voted in favor the Merger and the Agreement
         and the transactions contemplated thereby and that the
         Shareholder will not vote such Shares in favor of any Competing
         Transaction during the term of this letter agreement.

                   5.   The Shareholder has all necessary power and
         authority to enter into this letter agreement.  This letter
         agreement is the legal, valid and binding agreement of the
         Shareholder, and is enforceable against the Shareholder in
         accordance with its terms.

                   6.   The Shareholder agrees that damages are an
         inadequate remedy for the breach by Shareholder of any term or
         condition of this letter agreement and that you shall be
         entitled to a temporary restraining order and preliminary and
         permanent injunctive relief in order to enforce our agreements
         herein.  

                   7.   Except to the extent that the laws of the
         jurisdiction of organization of any party hereto, or any other
         jurisdiction, are mandatorily applicable to matters arising
         under or in connection with this letter agreement, this letter
         agreement shall be governed by the laws of the State of New
         York.  All actions and proceedings arising out of or relating

         the District of New York, for the purpose of any action or
         proceeding arising out of or relating to this letter agreement
         and each of the parties hereto irrevocably agrees that all
         claims in respect to such action or proceeding may be heard and
         determined exclusively in any New York state or federal court

         be conclusive and may be enforced in other jurisdictions by
         suit on the judgment or in any other manner provided by law.

         agreement among the parties hereto with respect to the matters
         covered hereby and supersedes all prior agreements,
         understandings or representations among the parties written or
