                   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
