                   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.


                                       -2-





         (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).  


                                       -5-





         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-





         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
         supersede all prior agreements and understandings, agreements
         or representations by or among the parties, written and oral,
         with respect to the subject matter hereof and thereof.

         (c)  Successors; No Third Party Beneficiaries.  The terms and
         conditions of this Option Agreement shall inure to the benefit
         of and be binding upon the parties hereto and their respective
         successors and permitted assigns.  Nothing in this Option
         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
         liabilities under or by reason of this Option Agreement, except
         as expressly provided herein.

         (d)  Notices.  All notices or other communications which are
         required or permitted hereunder shall be in writing and
         sufficient if delivered in accordance with Section 8.2 of the
         Merger Agreement (which is incorporated herein by reference).

         (e)  Counterparts.  This Option Agreement may be executed in
         counterparts, and each such counterpart shall be deemed to be
         an original instrument, but both such counterparts together
         shall constitute but one agreement.


                                       -8-





         (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
         its obligations under this Option Agreement, then either party
         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
         such injunctive or other equitable relief.  This provision is
         without prejudice to any other rights that either party hereto
         may have against the other party hereto for any failure to
         perform its obligations under this Option Agreement.

         (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
         under or in connection with this Option Agreement, this Option
         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
         New York state or federal court sitting in the City of New
         York.

         (i)  Consent to Jurisdiction; Venue.

                   (i)  Each of the parties hereto irrevocably submits
              to the exclusive jurisdiction of the state courts of New
              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
              process in any other action or proceeding relating hereto,
              on behalf of itself or its property, by the personal
              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


                                       -9-





         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
         entitled to the benefits of such provision.  This Option
         Agreement may not be modified, amended, altered or supplemented
         except upon the execution and delivery of a written agreement
         executed by the parties hereto.
