as again amended and restated in a Fourth Amendment dated December 2, 1997 (the

referred to as the "Schedule 13D"), with respect to the common stock of
PharMerica, Inc., f/k/a Capstone Pharmacy Services, Inc. (the "Issuer" or
"PharMerica"). The reporting persons named below are hereby jointly filing this
statement on Schedule 13D, pursuant to Rule 13d-1(f)(1) promulgated by the

         Item 2 is amended and supplemented as follows:

         Information as to the identity and background of the directors and

attached hereto, which is incorporated herein by reference.

         Neither Counsel nor, to the best knowledge of Counsel, any of the

violations or similar misdemeanors) or (b) has been a party to a civil
proceeding of a judicial or administrative body of competent jurisdiction and,
as a result of such proceeding, was or is subject to a judgment, decree or final
order enjoining future violations of, or prohibiting or mandating activity
subject to, federal or state securities laws or finding any violations with
respect to such laws.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.

         Item 5 is deleted in its entirety and replaced and supplemented by the
following:

         (a)      As of the close of business on November 8, 1998, (i) Counsel
                  beneficially owns in the aggregate 7,819,315 shares of the
                  Issuer's common stock and disclaims beneficial ownership of
                  all shares held by Mr. Silber, and (ii) Mr. Silber
                  beneficially owns in the aggregate 567,500 shares of the
                  Issuer's common stock and disclaims beneficial ownership of
                  all shares held


                                       4
<PAGE>   5
                  by Counsel. Counsel's and Mr. Silber's ownership constitute
                  8.7% and 0.6%, respectively, of the outstanding shares of the
                  Issuer's common stock, based upon 89,387,126 shares
                  outstanding as of November 2, 1998 (represented by Issuer's
                  quarterly report on Form 10-Q as the number of shares of the
                  Issuer's common stock outstanding as of such date) plus, with
                  respect to each party, the number of shares subject to options
                  or warrants held by such party.

                  Counsel has direct beneficial ownership of 7,819,315 shares of
                  the Issuer's common stock.

                  Mr. Silber has direct beneficial ownership of 95,000 shares of
                  the Issuer's common stock and options to acquire an additional
                  810,000 shares, of which 472,500 are vested.

                  Mr. Silber is a director of Counsel and a shareholder who
                  beneficially owns or controls approximately 17% of the common
                  shares of Counsel, a majority of which is pledged to a lender.
                  Each of Counsel and Mr. Silber disclaims beneficial ownership
                  of the shares of the Issuer beneficially owned by the other.

         (b)      Mr. Silber has the sole power to direct the vote and
                  disposition of the shares of which he possesses beneficial
                  ownership. Counsel shares its voting power and
                  disposition rights, as more fully set forth in Item 6, with
                  Bergen Brunswig Corporation ("Bergen"), a New Jersey
                  corporation and national drug wholesaler and distributor whose
                  principal office is 4000 Metropolitan Drive, Orange,
                  California 92868-3598. To the best knowledge of Counsel,
                  Bergen has not, during the last five years, (a) been convicted
                  in any criminal proceeding (excluding traffic violations or
                  similar misdemeanors) or (b) been a party to a civil
                  proceeding of a judicial or administrative body of competent
                  jurisdiction and, as a result of such proceeding, was or is
                  subject to a judgment, decree or final order enjoining future
                  violations of, or prohibiting or mandating activity subject
                  to, federal or state securities laws or finding any violations
                  with respect to such laws. The responses of Counsel
                  Corporation and Mr. Silber to Items (7) through (11) of the
                  portions of the cover page of this Schedule 13D that relate to
                  beneficial ownership are incorporated herein by reference.

         (c)      The following transaction was effected by the reporting person
                  since in the last 60 days:

                  See Item 6.

         (d)      Not Applicable.

         (e)      Not Applicable.

ITEM 6.           CONTRACTS, ARRANGEMENTS, UNDERSTANDING OR RELATIONSHIPS WITH
                  RESPECT TO SECURITIES OF THE ISSUER.

         On November 8, 1998, Counsel entered into a stock purchase agreement
(the "Agreement") between Counsel, Stadt Holdings Inc., a Delaware corporation
and an indirect wholly-owned subsidiary of Counsel ("Stadt"), Stadtlander Drug
Co., Inc. , a Delaware corporation and an indirect wholly-owned subsidiary of
Counsel ("Stadtlander"), and Bergen, whereby Bergen agreed to purchase all of
the issued and outstanding capital stock of Stadtlander for an estimated
purchase price of approximately $400,000,000 (consisting of cash, stock and
payment of debt) along with certain voting rights and disposition powers with
respect to the shares of PharMerica held by Counsel.

         Counsel has direct beneficial ownership of 7,819,315 shares of the
Issuer's common stock (the "PharMerica Shares"). Counsel has agreed to transfer
to Bergen, for a limited period of time and under limited circumstances, the
right to vote all of the PharMerica Shares on issues relating to any "business
combination" involving PharMerica. The term "business combination" refers to,
among other things, a merger, consolidation, share exchange, sale, transfer, or
other similar transaction. The voting rights granted to Bergen in respect of the
PharMerica Shares will terminate on December 31, 2001. In addition, Counsel has
covenanted that it will not sell, distribute to its shareholders or otherwise
dispose of any of the PharMerica Shares prior to December 31, 1999 (or December
25, 1999 in the case of a distribution to Counsel's shareholders) without the
prior written consent of Bergen. Bergen has also been granted a right of first
refusal to purchase all the PharMerica Shares in the event that Counsel receives
a bona fide offer from a third-party for such shares. If, following notice of
such third-party offer, Bergen declines to purchase the PharMerica Shares,
Counsel will be free to sell such shares to the third-party. Notwithstanding the
foregoing, if the sale to the third-party is not consummated within 120 days
from the date Bergen was notified of the offer, the Corporation must resubmit
the offer to Bergen for further consideration. In addition to and to effectuate
the rights created through the Agreement, at closing of the transaction, Counsel
will grant to Bergen an irrevocable proxy, a back-up option agreement and
certain rights pursuant to a voting trust agreement.

         The foregoing description of the voting rights and disposition powers
transferred by Counsel are qualified in their entirety by reference to the
Agreement, the irrevocable proxy, the back-up option agreement and the voting
trust agreement, copies of which are attached hereto as Exhibits 2.1, 2.2, 2.3
and 2.4 and incorporated by reference herein.

Report prepared pursuant to Section 2.5) exceeds the September 30 Net Worth plus
(iii) the amount, if any, by which the Final Net Debt is less than One Hundred
Million Dollars ($100,000,000) minus (iv) the amount, if any, by which the
September 30 Net Worth exceeds the Net Worth as of the Closing Date (as
reflected in the Final Accounting Report prepared pursuant to Section 2.5) minus
(v) the amount, if any, by which the Final Net Debt is greater than One Hundred
Million Dollars ($100,000,000) and minus (vi) the Total Option Appreciation.

                  2.2.2    Payment of the Estimated Net Purchase Price. Subject 
to Section 2.2.4, upon the terms and subject to the conditions of this Agreement
and on the basis of the representations, warranties and agreements contained
herein, at the Closing, the Purchaser shall pay the Estimated Net Purchase Price
to the Sellers by (i) paying to the Canadian Seller in cash a sum equal to
13.96% of the Estimated Net Purchase Price by wire transfer to an account or
accounts specified in writing by the Canadian Seller, (ii) paying to the US
Seller in cash a sum equal to 36.04% of the Estimated Net Purchase Price by wire
transfer to an account or accounts specified in writing by the US Seller and
(iii) issuing and delivering to the US Seller a stock certificate, registered in
the US Seller's name, representing a number of shares of BBC Common Stock equal
to 


                                      -11-
<PAGE>   12

(x) 50% of the Estimated Net Purchase Price divided by (y) the Market Value.
In order to assure that the number of shares of BBC Common Stock to be issued
pursuant to this Section 2.2.2 properly gives effect to the Stock Split, the
following provisions shall apply:

                  2.2.2.1  In the event that the last sale price, regular way,
of the BBC Common Stock on the New York Stock Exchange (the "Last Price") does
not reflect the Stock Split for any trading day during the Market Price Period
and the Closing occurs prior to December 1, 1998, then, on December 1, 1998, the
Purchaser shall treat the shares issued pursuant to Section 2.2.2 as if they had
been issued on the record date for the Stock Split.

                  2.2.2.2  In the event that the Last Price does not reflect the
Stock Split for any trading day during the Market Price Period and the Closing
occurs on or after December 1, 1998, then the number of shares to be issued
pursuant to Section 2.2.2 at the Closing shall be equitably adjusted to give
effect to the Stock Split.

                  2.2.2.3  In the event that the Last Price reflects the Stock
Split for one or more trading days during the ten trading days utilized to
determine the Market Value, then the Closing shall not be held prior to December
1, 1998, notwithstanding any provision herein to the contrary.

                  2.2.3    Adjustments to the Estimated Net Purchase Price.

                           2.2.3.1  Increased Consideration.  Subject to Section
2.2.4, if the Net Purchase Price is greater than the Estimated Net Purchase
Price, then, upon final determination of the Net Worth as of the Closing Date
and the Net Debt as of the Closing Date pursuant to Section 2.5 and calculation
of the amount by which the Net Purchase Price exceeds the Estimated Net Purchase
Price (such excess amount, the "Increased Consideration"), the Purchaser shall
pay the Increased Consideration to the Sellers by (i) paying to the Canadian
Seller in cash a sum equal to 13.96% of the Increased Consideration by wire
transfer to an account or accounts specified in writing by the Canadian Seller,
(ii) paying to the US Seller in cash a sum equal to 36.04% of the Increased
Consideration by wire transfer to an account or accounts specified in writing by
the US Seller and (iii) issuing and delivering to the US Seller a stock
certificate, registered in the US Seller's name, representing a number of shares
of BBC Common Stock equal to (x) 50% of the Increased Consideration divided by
(y) the Market Value.

                           2.2.3.2  Decreased Consideration.  Subject to Section
2.2.4, if the Net Purchase Price is less than the Estimated Net Purchase Price,
then, upon final determination of the Net Worth as of the Closing Date and the
Net Debt as of the Closing Date pursuant to Section 2.5 and calculation of the
amount by which the Estimated Net Purchase Price exceeds the Net Purchase Price
(such excess amount,


                                      -12-
<PAGE>   13

the "Decreased Consideration"), the Sellers shall refund the Decreased
Consideration to the Purchaser as follows: (i) the Canadian Seller shall pay to
the Purchaser in cash a sum equal to 13.96% of the Decreased Consideration by
wire transfer to an account or accounts specified in writing by the Purchaser,
(ii) the US Seller shall pay to the Purchaser in cash a sum equal to 36.04% of
the Decreased Consideration by wire transfer to an account or accounts specified
in writing by the Purchaser and (iii) the US Seller shall transfer to the
Purchaser a stock certificate, registered in the US Seller's name and duly
endorsed for transfer, representing a number of shares of BBC Common Stock equal
to (x) 50% of the Decreased Consideration divided by (y) the Market Value.

                  2.2.4    Notwithstanding any provision herein to the contrary,
if the Market Value is less than $49.625 (subject to the proviso in the
definition of the term "Market Value" regarding the Stock Split), the Purchaser
shall have the right to change the nature of the consideration to be paid to the
Sellers in accordance with the following provisions:

                           2.2.4.1  At any time prior to the consummation of the
Closing, the Purchaser shall have the right to deliver to the Sellers a notice
(the "Cash Election Notice") advising the Sellers that the Purchaser desires to
pay the entire Net Purchase Price in cash rather than pay the Net Purchase Price
partly in cash and partly in shares of BBC Common Stock. In the event that the
Purchaser delivers a Cash Election Notice to the Sellers prior to the
consummation of the Closing, then, notwithstanding any provision herein to the
contrary, the following provisions shall apply:

                                    2.2.4.1.1  The Purchaser shall not have any
obligation to issue or deliver any shares of BBC Common Stock pursuant to
Section 2.2.2 and Sections 2.2.2.1, 2.2.2.2 and 2.2.2.3 shall cease to apply.

                                    2.2.4.1.2  In addition to the cash payments 
contemplated by clauses (i) and (ii) of Section 2.2.2 and in lieu of the
issuance of shares of BBC Common Stock pursuant to clause (iii) of Section
2.2.2, the Purchaser shall pay to the US Seller in cash a sum equal to 50% of
the Estimated Net Purchase Price by wire transfer to an account or accounts
specified in writing by the US Seller.

                                    2.2.4.1.3  If the Net Purchase Price is 
greater than the Estimated Net Purchase Price, the Purchaser shall not have any
obligation to issue or deliver any shares of BBC Common Stock pursuant to
Section 2.2.3.1.

                                    2.2.4.1.4  If the Net Purchase Price is 
greater than the Estimated Net Purchase Price, then, in addition to the cash
payments contemplated by clauses (i) and (ii) of Section 2.2.3.1 and in lieu of
the issuance of shares of BBC Common Stock pursuant to clause (iii) of Section
2.2.3.1, the Purchaser shall pay to the US Seller in cash a sum equal to 50% of
the Increased Consideration by wire transfer 


                                      -13-
<PAGE>   14

to an account or accounts specified in writing by the US Seller.

                                    2.2.4.1.5  If the Net Purchase Price is less
than the Estimated Net Purchase Price, the Sellers shall not have any obligation
to refund any shares of BBC Common Stock pursuant to Section 2.2.3.2.

                                    2.2.4.1.6  If the Net Purchase Price is less
than the Estimated Net Purchase Price, then, in addition to the cash refunds
contemplated by clauses (i) and (ii) of Section 2.2.3.2 and in lieu of the
refund of shares of BBC Common Stock pursuant to clause (iii) of Section
2.2.3.2, the US Seller shall refund to the Purchaser in cash a sum equal to 50%
of the Decreased Consideration by wire transfer to an account or accounts
specified in writing by the US Seller.

                           2.2.4.2  In the event that the Purchaser delivers a 
Cash Election Notice to the Sellers prior to the consummation of the Closing,
Sections 2.3 and 2.4 of this Agreement shall cease to apply.

                           2.2.4.3  In the event that (i) the Purchaser delivers
a Cash Election Notice to the Sellers prior to the consummation of the Closing
and (ii) there is an inconsistency between this Section 2.2.4 and any other
provision of this Agreement, the provisions of this Section 2.2.4 shall govern.

                  2.2.5    Notwithstanding any provision herein to the contrary,
the Purchaser shall not issue fractional shares of BBC Common Stock hereunder.
In lieu of issuing a fractional share, the Purchaser shall pay a cash amount
equal to the applicable fraction multiplied by the Market Value, as equitably
adjusted to reflect the Stock Split.



            Section 2.3    Securities Law Matters.

                  2.3.1    Private Offering. The Sellers acknowledge that the
shares of BBC Common Stock to be issued and delivered to the Sellers hereunder
(the "BBC Shares") will not be registered under the Securities Act of 1933, as
amended (the "Act"), but will be issued in reliance upon the exemption afforded
by Section 4(2) of the Act, and that the Purchaser is relying upon the truth and
accuracy of the representations set forth in Section 4.7. Each certificate
representing BBC Shares issued pursuant to this Agreement shall bear the
following legends:

                  "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ISSUED
         WITHOUT REGISTRATION PURSUANT TO THE SECURITIES ACT OF 1933, AS
         AMENDED, OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION, AND
         MAY NOT BE TRANSFERRED UNLESS THEY ARE SO REGISTERED OR, IN THE 


                                      -14-
<PAGE>   15

         OPINION OF COUNSEL REASONABLY ACCEPTABLE TO THIS CORPORATION, SUCH
         TRANSFER IS EXEMPT FROM REGISTRATION."

                  "IN THE EVENT THAT THE SHARES REPRESENTED BY THIS CERTIFICATE
         ARE REGISTERED FOR RESALE PURSUANT TO THE ABOVE-MENTIONED LAWS, SUCH
         SHARES MAY ONLY BE TRANSFERRED BY SALE ON THE NEW YORK STOCK EXCHANGE
         PURSUANT TO SEC RULE 153 WHILE SUCH REGISTRATION IS EFFECTIVE, UNLESS,
         IN THE OPINION OF COUNSEL REASONABLY ACCEPTABLE TO THIS CORPORATION,
         SUCH TRANSFER IS EXEMPT FROM REGISTRATION."

The Purchaser shall give instructions to its transfer agent consistent with the
foregoing legends.

                  2.3.2    No Transfer. The Sellers will not sell, pledge or
otherwise transfer the BBC Shares unless the BBC Shares are registered under the
Act and under all applicable securities laws of other jurisdictions or are
exempt therefrom in the opinion of counsel reasonably satisfactory to the
Purchaser, it being agreed that Harwell Howard Hyne Gabbert & Manner, P.C. is
acceptable to the Purchaser.

                  2.3.3    Agreement to Register. Prior to the Closing, the
Purchaser shall prepare a registration statement on Form S-3 (the "Registration
Statement") pursuant to the Act covering the resale of BBC Shares to be issued
pursuant to this Agreement and shall file such Registration Statement with the
SEC on or before the first Business Day following the Closing, provided that the
Purchaser has available to it, in form satisfactory for filing, any consolidated
financial information and pro forma financial information regarding the Company
necessary or appropriate for filing with the SEC. The Purchaser and the Sellers
shall both use their best efforts to expedite the preparation of such
information to the maximum extent practicable. Subsequent to the initial filing
of the Registration Statement, the Purchaser shall thereafter use its best
efforts to have such Registration Statement (covering the resale of all of the
BBC Shares to be issued pursuant to this Agreement) declared effective by the
Securities and Exchange Commission ("SEC") promptly after the Closing Date, and
to keep that Registration Statement current, subject to the provisions set forth
in Appendix 2.3.7 annexed hereto regarding the temporary suspension of use of
the Registration Statement, until the two year anniversary of the Closing Date.
The Purchaser reserves the right to include other shares of BBC Common Stock in
the Registration Statement, provided that such inclusion does not adversely
affect the Sellers in any substantive respect. The Purchaser agrees to use its
best efforts to cover in the Registration Statement, either initially or by
amendment when applicable, any of the BBC Shares which are pledged by one or
more of the Sellers to a lender and subsequently resold by such lender upon a
default by the applicable borrower and any other BBC Shares which 


                                      -15-
<PAGE>   16

are held by a Person to whom registration rights are transferred in accordance
with Section 2.3.6.

                  2.3.4    Costs. The Purchaser shall bear all costs incurred in
preparing and filing the Registration Statement, including, without limitation,
all applicable legal fees (excluding the fees of counsel to the Sellers),
accounting fees, printing fees, and SEC filing fees; provided, however, that the
Purchaser shall not be responsible for any underwriting commissions or
discounts, brokerage fees or legal fees or disbursements incurred by any person
or entity (other than the Purchaser) that sells any shares of BBC Common Stock
pursuant to the Registration Statement. Subject to the qualifications in the
immediately preceding sentence, the Purchaser shall also bear all costs of
keeping the Registration Statement current during the applicable period
described in Section 2.3.3.

                  2.3.5    Information. The Sellers will furnish the Purchaser
with all information concerning the Sellers reasonably required for inclusion in
the Registration Statement. The Sellers and the Purchaser represent and warrant
that no information to be furnished for the Registration Statement will contain
any statement which, at the time and in the light of the circumstances under
which it is made, is false or misleading with respect to any material fact, or
which omits to state any material fact necessary in order to make the statements
therein not false or misleading or necessary to correct any statement in any
earlier information furnished hereunder which has become false or misleading.

                  2.3.6    Personal Rights. The registration rights set forth in
this Section 2.3 are personal to the Sellers and may not be transferred or
assigned by the Sellers to any other person or entity other than (a) an
Affiliate of the Canadian Seller or the US Seller, (b) a lender who receives
such shares in accordance with Section 2.4 and pursuant to a bona pledge by the
Canadian Seller or the US Seller or (c) a Qualified Investor, provided, however,
that such rights shall not be assigned to a Qualified Investor unless the
Purchaser was offered the opportunity, in writing , to purchase the BBC Shares
offered to the Qualified Investor on terms no less favorable to the Purchaser
than the terms offered to the Qualified Investor, the Purchaser did not accept
such offer within ten Business Days of the date that the offer is delivered to
the Purchaser and the Qualified Investor completes such purchase within 120 days
of the date that such offer was made to the Purchaser.

                  2.3.7    Registration Rights. The Purchaser and the Sellers
shall abide by the registration rights provisions set forth in Appendix 2.3.7
annexed hereto.

            Section 2.4    Restrictions on Sales and Other Transfers.

                  2.4.1    General Restrictions. Except as otherwise provided in
Section 2.4.2, during the first 540 calendar days after the Closing Date, the
Sellers shall not (x)


                                      -16-
<PAGE>   17

effect an offer, pledge (other than a pledge which, by its terms, subjects the
pledgee to the same restrictions to which the Sellers are subject under this
Section 2.4 pursuant to an agreement acceptable to the Purchaser, such
acceptance not to be unreasonably withheld), sale, contract of sale, sale of any
option or contract to purchase, purchase of any option or contract to sell,
grant of any option, right or warrant to purchase, or other transfer or
disposition of , directly or indirectly, any of the BBC Shares or any securities
convertible into or exercisable or exchangeable for the BBC Shares (including,
without limitation, BBC Shares or securities convertible into or exercisable or
exchangeable for BBC Shares which may be deemed to be beneficially owned by the
Sellers in accordance with the rules and regulations of the SEC) or (y) enter
into any swap or other arrangement that transfers all or a portion of the
economic consequences associated with the ownership of any BBC Shares
(regardless of whether any of the transactions described in clause (x) or (y)
(each, a "Disposition") are to be settled by the delivery of BBC Shares, or such
other securities, in cash or otherwise). The Sellers authorize the Purchaser to
cause the Purchaser's transfer agent to decline to transfer and/or to note stop
transfer restrictions on the transfer books and records of the Purchaser with
respect to any of the BBC Shares and any securities convertible into or
exercisable or exchangeable for the BBC Shares for which the Sellers are the
beneficial or record holder and agree to cause the record holder to cause the
transfer agent to decline to transfer and/or to note stop transfer restrictions
on such books and records with respect to such shares or securities except to
the extent that such transfers are permitted pursuant to this Agreement.

                  2.4.2    Sequential Lapse of Restrictions. During the First
Quarterly Period, the Sellers have the right to make a Disposition of up to
thirty percent (30%) of the BBC Shares issued to the Sellers at the Closing or
subsequent to the Closing pursuant to the terms hereof (the "BBC Delivered
Shares"), less any such BBC Delivered Shares which are subject to a Disposition
by or on behalf of any lender during the First Quarterly Period upon default of
any loan made to either of the Sellers. During each of the Second Quarterly
Period, Third Quarterly Period, Fourth Quarterly Period and Fifth Quarterly
Period (each, a "Quarterly Period"), the Sellers shall have the right to effect
a Disposition of up to (x) ten percent (10%) of the BBC Delivered Shares, less
any BBC Delivered Shares which are subject to a Disposition by or on behalf of
any lender during such current Quarterly Period upon default of any loan made to
either of the Sellers, plus any BBC Delivered Shares which the Sellers had the
right to subject to a Disposition, but did not subject to a Disposition, during
any prior Quarterly Period; provided, however, that the Sellers shall not
subject to a Disposition more than thirty percent (30%) of the BBC Delivered
Shares in any one Quarterly Period, less any BBC Delivered Shares which are
subject to a Disposition by or on behalf of any lender during such Quarterly
Period upon default of any loan made to either of the Sellers. During the Sixth
Quarterly Period, the Sellers shall have the right to subject to a Disposition
up to thirty percent (30%) of the BBC Delivered Shares, less any BBC Delivered
Shares which are subject to a Disposition by or on behalf of any lender during
the Sixth Quarterly Period upon default of any loan made to either of the
Sellers. The 


                                      -17-
<PAGE>   18

restrictions set forth in Section 2.4.1 shall cease to apply after the last day
of the Sixth Quarterly Period. In the event that either of the Sellers utilize
any of the BBC Delivered Shares as collateral on a loan on or before the last
day of the Sixth Quarterly Period, the Sellers shall require that the lender
execute an agreement, a copy of which shall be delivered to the Purchaser and
shall be acceptable to the Purchaser, such acceptance not to be unreasonably
withheld, that (a) expressly states that the lender will not effect a
Disposition of a greater number of BBC Delivered Shares in any of the
above-mentioned periods than the Sellers are entitled to subject to a
Disposition in such periods and (b) acknowledges that the Purchaser is entitled
to rely upon such agreement.

                  2.4.3    The Sellers agree that the certificates representing 
the BBC Shares shall also bear a legend referring to the restrictions set forth
in this Section 2.4.

            Section 2.5    Determination of the Net Worth as of the Closing 
                           Date.

                  2.5.1    Accountants' Reports.

                           2.5.1.1  Proposed  Statement and Initial Accounting 
Report. The Sellers shall prepare at their expense, and furnish to the Purchaser
and CPA, a proposed consolidated balance sheet of the Company as of the Closing
Date prepared in accordance with GAAP, consistently applied (the "Proposed
Statement"). Such Proposed Statement shall provide sufficient detail to
establish, among other things, the Net Debt as of the Closing Date and the Net
Worth as of the Closing Date . The CPA shall submit the Proposed Statement to a
Limited Audit and, based upon the results of that Limited Audit, the Purchaser
shall render a draft report (the "Initial Accounting Report") to the Sellers and
the Purchaser with respect to the Net Worth as of the Closing Date and the Net
Debt as of the Closing Date. As soon as practicable, but, in any event, not more
than ninety (90) calendar days after the Purchaser receives the Proposed
Statement and any information that the Purchaser or the CPA reasonably and
promptly requests from the Sellers and/or the Accountants to complete the
Initial Accounting Report, the Purchaser shall furnish the Initial Accounting
Report to the Sellers, along with a schedule of the adjustments made to the
Proposed Statement.

                           2.5.1.2  Time for Objections.  After the Purchaser 
shall have furnished the Initial Accounting Report to the Sellers, if the
Sellers should object to that report on the grounds that it is not consistent
with GAAP, consistently applied, the Sellers may give written notice of their
objection to the Purchaser within twenty (20) calendar days after the Sellers'
receipt of that report. If requested by the Sellers at the time of delivery of
such notice, the Purchaser shall cause the CPA promptly to make available to the
Sellers and the Accountants any report prepared by the CPA with respect to the
matters in dispute in connection with the Initial Accounting Report. If no such
objection is made within such twenty (20) day period, or if the Purchaser and
the Sellers agree upon all matters in dispute, that Initial Accounting Report,
as adjusted to


                                      -18-
<PAGE>   19

reflect any such agreements, shall be final and binding on all parties hereto
for the purpose of determining the Net Worth as of the Closing Date and the Net
Debt as of the Closing Date and shall be referred to as the "Final Accounting
Report".

                           2.5.1.3  Dispute Resolution.  If the Purchaser and 
the Sellers are unable to resolve all items in dispute (with respect to the
calculation of the Net Worth as of the Closing Date and the Net Debt as of the
Closing Date) within fifteen (15) calendar days after the Purchaser's receipt of
the Sellers' written objections to the Initial Accounting Report, then those
items in dispute shall be submitted for resolution to a firm of independent
certified public accountants acceptable to the Sellers and the Purchaser (the
"Firm"). The Firm shall resolve such disputes by application of GAAP,
consistently applied, and such procedures as the Firm, in its discretion,
determines to be appropriate. The determination of the Firm with respect to
those items in dispute, together with the determinations of the Purchaser and
the Sellers with respect to those items not in dispute, shall become the "Final
Accounting Report" and shall be final and binding upon all parties hereto for
purposes of determining the Net Worth as of the Closing Date and the Net Debt as
of the Closing Date. The Purchaser and the Sellers will use reasonable efforts
to resolve these matters as rapidly as possible.

                           2.5.1.4  Payment of Fees.  The Sellers shall pay the
fees of its accountants, including without limitation the Accountants to the
extent that the Accountants are involved, in connection with the preparation
and/or review of the Proposed Statement, the Initial Accounting Report and/or
the Final Accounting Report and the Purchaser shall pay the fees of the CPA,
including fees in connection with the preparation and/or review of the Initial
Accounting Report and the Final Accounting Report. The fees and disbursements of
any Firm employed pursuant to the provisions of Section 2.5.1.3 shall be borne
one-half by the Purchaser and one-half by the Sellers.

                  2.5.2    Asset Value. In determining the Net Worth as of the
Closing Date, the consolidated assets of the Company and its Subsidiaries shall
be valued as of the Closing Date in accordance with GAAP, consistently applied.

                  2.5.3    Liability Value. In determining the Net Worth as of 
the Closing Date, the consolidated liabilities of the Company and its
Subsidiaries shall be valued as of the Closing Date in accordance with GAAP,
consistently applied, provided that notwithstanding any provision herein to the
contrary and regardless of the application of GAAP, any prepayment fees,
breakage fees or similar fees paid by any of the Companies or the Purchaser at
or after the Closing with respect to any indebtedness of any of the Companies as
of the Closing Date shall be treated as a liability of the Companies as of the
Closing Date for purposes of determining the Net Worth as of the Closing Date.

            Section 2.6    Determination of September 30 Net Worth.  The 
September 30 Net Worth shall be determined in accordance with Section 6.22.

            Section 2.7    Closing. Subject to the rights of the parties to 
terminate this Agreement in accordance with Article VIII and subject to Sections
2.2.2.3 and 6.22.4, the closing of the transactions contemplated hereby (the
"Closing") shall take place at the offices of Lowenstein Sandler PC, 65
Livingston Avenue, Roseland, New Jersey, at 10:00 A.M. on the fifth Business Day
after the satisfaction or waiver of the conditions set forth in Article VII (but
in no event prior to the twenty-first calendar day after the Purchaser receives
the Interim Audited Financial Statements pursuant to Section 6.22), or at such
other time and place as is mutually agreed by the Purchaser and the Seller. The
time and date of the Closing is herein called the "Closing Date".

                                   ARTICLE III

             REPRESENTATIONS AND WARRANTIES REGARDING THE COMPANIES

                  The Company, the Canadian Seller and the US Seller jointly and
severally represent and warrant to the Purchaser as follows:

            Section 3.1.   Organization and Standing; Business. Each of the
Companies is a corporation or limited liability company duly organized, validly
existing and in good standing under the laws of the state of its organization
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 the Companies 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 result in a Material Adverse

                                    ARTICLE V

             REPRESENTATIONS AND WARRANTIES REGARDING THE PURCHASER

         The Purchaser represents and warrants to the Sellers and the Company as
follows:

         Section 5.1 Organization and Standing. The Purchaser is a corporation
duly organized, validly existing and in good standing under the laws of the
state of New Jersey with full power and authority (corporate and other) to own,
lease, use and operate its properties and to conduct its business as and where
now owned, leased, used, operated and conducted. The Purchaser is duly licensed
or qualified to do business and is 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 result in a
Material Adverse Change with respect to the Purchaser and its subsidiaries,
taken as a whole. The copies of the Restated Certificate of Incorporation and
by-laws of the Purchaser previously provided to the Sellers' counsel are true,
correct and complete copies of such documents as in effect as of the date of
this Agreement.

         Section 5.2 Corporate Power and Authority. The Purchaser has all
requisite corporate power and authority to enter into the Transaction Agreements
and to consummate the transactions contemplated by the Transaction Agreements.
The execution and delivery of the Transaction Agreements and the consummation of
the



                                      -41-
<PAGE>   42


transactions contemplated hereby and thereby have been duly authorized by all
necessary corporate action on the part of the Purchaser. No other corporate
proceedings on the part of the Purchaser are necessary to consummate the
transactions contemplated by the Transaction Agreements. Each of the Transaction
Agreements has been (or, in the case of agreements to be executed at the
Closing, will be) duly executed and delivered by the Purchaser, and constitutes
(or, in the case of agreements to be executed at the Closing, will constitute)
the legal, valid and binding obligation of the Purchaser enforceable against the
Purchaser in accordance with its terms, except insofar as its enforcement may be
limited by (a) bankruptcy, insolvency, moratorium or similar laws affecting the
enforcement of creditors' rights generally and (b) equitable principles limiting
the availability of equitable remedies. All persons who executed this Agreement
on behalf of the Purchaser have been duly authorized to do so.

         Section 5.3 Capitalization of the Purchaser. As of September 30, 1998,
the Purchaser's outstanding capital stock consisted solely of shares of BBC
Common Stock, of which 51,441,165 shares were issued and outstanding. As of
September 30, 1998, 2,594,472 shares of BBC Common Stock were reserved for
issuance upon the exercise or conversion of outstanding options, warrants or
convertible securities granted or issuable by the Purchaser. Each outstanding
share of BBC Common Stock is, and all shares of BBC Common Stock to be issued in
connection with the transactions contemplated hereby will be, duly authorized
and validly issued, fully paid and nonassessable, with no personal liability
attaching to the ownership thereof, and each outstanding share of BBC Common
Stock has not been, and all shares of BBC Common Stock to be issued in
connection with the transactions contemplated hereby will not be, subject to or
issued in violation of any preemptive or similar rights. As of September 30,
1998, except as set forth above or in the "BBC SEC Documents" (as defined
herein) and except for shares issuable in connection with business acquisitions,
the Purchaser did not have and was not bound by any outstanding subscriptions,
options, warrants, calls, commitments or agreements of any character calling for
the purchase or issuance of any shares of BBC Common Stock or BBC Preferred
Stock or any other equity securities of the Purchaser or any securities
representing the right to purchase or otherwise receive any shares of BBC Common
Stock or BBC Preferred Stock.

         Section 5.4 Conflicts; Consents and Approvals. Except as set forth in
Section 5.4 to the disclosure schedule delivered by the Purchaser to the Sellers
and dated the date hereof (the "Purchaser's Disclosure Schedule"), neither the
execution and delivery of the Transaction Agreements by the Purchaser nor the
consummation of the transactions contemplated hereby or thereby will:

               5.4.1 conflict with, or result in a breach of any provision of,
the Purchaser's restated certificate of incorporation or by-laws, as amended;



                                      -42-
<PAGE>   43


               5.4.2 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 the Purchaser 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 the Purchaser or any of its subsidiaries is a party;

               5.4.3 violate any order, writ, injunction, decree, statute, rule
or regulation applicable to the Purchaser or any of its subsidiaries or their
respective properties or assets; or

               5.4.4 require any action or consent or approval of, or review by,
or registration or filing by the Purchaser or any of its Affiliates with, any
third party or any Governmental Authority, other than (i) registrations or other
actions required under federal and state securities laws as are contemplated by
this Agreement, or (ii) as required by the HSR Act,

except, in the case of Sections 5.4.2, 5.4.3 and 5.4.4, for any of the foregoing
that would not, individually or in the aggregate, have a material adverse effect
on the consolidated financial condition or consolidated results of operations of
the Purchaser or upon the ability of the parties to consummate the transactions
contemplated hereby.

         Section 5.5 Brokers. With the exception of Lehman Brothers, no Person
is or will be entitled to a broker's, finder's, investment banker's, financial
adviser's or similar fee from the Purchaser in connection with this Agreement or
any of the transactions contemplated hereby. The fees and expenses of Lehman
Brothers are the sole responsibility of, and shall be paid by, the Purchaser.

         Section 5.6 BBC SEC Documents and Other Public Disclosures.

               5.6.1 The Purchaser has timely filed with the SEC all forms,
reports, schedules, statements and other documents required to be filed by it
since September 1, 1996 under the Exchange Act (such documents, as supplemented
and amended since the time of filing, collectively, the "BBC SEC Documents").
The BBC SEC Documents, including, without limitation, any financial statements
or schedules included therein, at the time filed (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) complied
in all material respects with the applicable requirements of the Exchange Act.
The Purchaser has previously provided to the



                                      -43-
<PAGE>   44


Sellers" counsel true, correct and complete copies of the BBC SEC Documents. The
financial statements of the Purchaser included in the BBC SEC Documents at the
time filed complied as to form in all material respects with applicable
accounting requirements and with the published rules and regulations of the SEC
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 SEC), and fairly present (subject,
in the case of unaudited statements, to normal, recurring audit adjustments) the
consolidated financial position of the Purchaser and its consolidated
subsidiaries as at the dates thereof and the consolidated results of their
operations and cash flows for the periods then ended.

               5.6.2 Since December 31, 1997, except for events publicly
disclosed by the Purchaser prior to the date hereof, there has been no change in
the assets, liabilities, results of operations or financial condition of the
Purchaser and its Subsidiaries which would constitute a Material Adverse Change
with respect to the Purchaser and its Subsidiaries taken as a whole or any
event, occurrence or development which would have a material adverse effect on
the ability of the Purchaser to consummate the transactions contemplated hereby.

         Section 6.1 Access and Information. Prior to the Closing, the Purchaser
shall be entitled to make or cause to be made such investigation of the

                                      -44-
<PAGE>   45


Transaction Agreements. Except with respect to publicly available documents, in
the event that this Agreement is terminated, (a) the Purchaser will deliver to
the Company all documents obtained by it from the Companies or the Sellers in

Sellers and the Company will deliver to the Purchaser all documents obtained by
them from the Purchaser in confidence and any copies thereof in the possession
of the Company and/or either of the Sellers or their agents and representatives
or, at the option of the Company and the Sellers, the Company and the Sellers
shall cause all of such documents and all of such copies to be destroyed and
shall certify the destruction thereof to the Purchaser.

         No investigation by the Purchaser heretofore or hereafter made shall
modify or otherwise affect (a) any representations and warranties of the Company
or the Sellers made pursuant to this Agreement, which shall survive any such
investigation, or (b) the conditions to the obligation of the Purchaser to
consummate the transactions contemplated hereby, provided that the Purchaser
shall promptly notify the Sellers in writing of any facts and circumstances of
which it obtains knowledge prior to the Closing that indicate that any such
representations and warranties are inaccurate in any material respect (except
for any representation and warranty which is qualified hereunder as to
materiality, as to which such notification shall be given if the Purchaser
obtains knowledge that such representation and warranty is inaccurate in any
respect); failure to comply with this notification obligation with respect to
particular facts and circumstances shall preclude the Purchaser from relying
upon such facts and circumstances in bringing any action hereunder for
indemnification.

affect adversely the validity or enforcement thereof; maintain its other assets

<PAGE>   48


on the Closing Date, execute and deliver, or cause to be executed and delivered
to the Purchaser, the documents or instruments described in Section 7.2. The
Purchaser shall, prior to or on the Closing Date, execute and deliver, or cause
to be executed and delivered, to the Sellers, the documents or instruments
described in Section 7.3.

               6.5.1 The Sellers shall pay any stamp, stock transfer, sales,

arising out of or resulting from the purchase of the Stadtlander Shares. The
Sellers shall prepare and file the required Tax returns and other required
documents with respect to the Taxes and fees required to be paid by them
pursuant to the preceding sentence and shall promptly provide the Purchaser with
evidence of the payment of such Taxes and fees.

               6.5.2 The US Seller shall include the income of the Companies
(including any deferred income triggered into income by Treas. Reg.
ss.ss.1.1502-13 or any predecessor regulation and any excess loss accounts taken
into income under Treas. Reg. ss.ss.1.1502-19) on the US Seller's consolidated
federal income Tax returns for all periods through the Closing Date and pay any
federal income taxes attributable to such income. The Companies shall furnish
Tax information to the US Seller for inclusion in the US Seller's consolidated
federal income tax return and state and local income or franchise tax returns
for the period which includes the Closing Date in accordance with the Companies'
past custom and practice. The US Seller shall allow the Purchaser an opportunity
to review and comment upon such Tax returns (including any amended returns) to
the extent that they relate to the Companies and would adversely affect the
Purchaser or the Companies after the Closing Date. The income of the Companies

close of business on the Closing Date. Notwithstanding the foregoing,
information which is subject to a confidentiality agreement shall not be
released except to the extent required by law.

before the Closing, the Sellers shall provide to the Purchaser evidence of such
termination, in form satisfactory to the Purchaser.

               6.5.4 The US Seller shall allow the Purchaser and its counsel to

returns to the extent that such returns relate to the Companies. The US Seller
shall not settle any such audit in a manner that would adversely affect the
Companies after the Closing Date without the Purchaser's prior written consent,
which consent shall not be unreasonably withheld.

<PAGE>   49


               6.5.5 The US Seller shall immediately pay to the Purchaser any
Tax refund (or reduction in Tax liability) resulting from a carryback of a
post-acquisition Tax attribute of any of the Companies into the US Seller's
consolidated Tax return, when such refund or reduction is realized by the US
Seller's group. The US Seller shall cooperate with the Companies in obtaining
any such refund (or reduction in Tax liability), including through the filing of
amended Tax returns or refund claims. The Purchaser agrees to indemnify the US
Seller for any Taxes resulting from the disallowance of such post-acquisition
Tax attribute on audit or otherwise.

               6.5.6 The US Seller will not elect to retain any net operating
loss carryovers or capital loss carryovers of the Companies under Treas. Reg.

               6.5.7 Prior to the Closing, the Canadian Seller shall furnish the
Purchaser with a statement issued by the Company pursuant to Treas. Reg.
ss.1.897-2(h) by which statement the Company certifies that the Stadtlander
Shares are not United States real property interests within the meaning of
Section 897(c) of the Code.

         Section 6.6 Non-Competition and Confidentiality Agreement. For a period
of five years after the Closing Date, the Sellers will not, and the Sellers will
cause their Subsidiaries (other than Subsidiaries that are not at least
majority-owned) not to, (a) directly or indirectly, anywhere within the United
States, engage in a Competitive Business or (b) without the written consent of
the Purchaser, directly or indirectly employ, engage, contract for or solicit
the services in any capacity of any Person (other than Allan Silber, Morris
Perlis or James Sas) who is employed by any of the Companies on the date hereof,
unless the employment of such Person is terminated by the Purchaser prior to any
solicitation of employment or employment; or (c) use for its own benefit or
divulge or convey to any third party, any Confidential Information (as
hereinafter defined) relating to any of the Companies. For purposes of this
Agreement, the Sellers shall not be deemed to have violated clause (a) of this
Section 6.6 in the event that (i) the Sellers or their Affiliates acquire the
capital stock or a substantial portion of the assets of a Person whose revenues
during its last fiscal year attributable to a Competitive Business represent (x)
less than $50,000,000 and (y) less than twenty five percent (25%) of such
Person's aggregate revenues, (ii) the Sellers promptly offer to sell such
Competitive Business to the Purchaser on commercially reasonable terms at a
price that is either agreed upon by the Sellers and the Purchaser or is
determined by a valuation firm mutually acceptable to the Sellers and the
Purchaser to represent the fair market value of such Competitive Business and
(iii) if the Purchaser does not accept such offer, the Sellers dispose of the
Competitive Business promptly, but in no event more than twelve months after the
acquisition of the Competitive Business by the Sellers. For purposes of this
Agreement, the Sellers shall not be deemed to have violated clause (a) of this
Section 6.6 by virtue of their combined ownership (together with the ownership
of their Subsidiaries) of (x) less than five percent (5%) of the issued



                                      -49-

and outstanding stock of a publicly held corporation, (y) the shares of the
capital stock of PharMerica or (z) shares of the capital stock of American Home
Patient Inc., a Delaware corporation. For purposes of this Agreement,
"Confidential Information" consists of all information, knowledge or data
relating to any of the Companies including, without limitation, customer and
supplier lists, formulae, trade know-how, processes, secrets, consultant
contracts, pricing information, marketing plans, product development plans,
business acquisition plans and all other information relating to the operation
of the Companies not in the public domain or otherwise publicly available which
are or were treated as confidential by the Companies. Information which enters
the public domain or is publicly available loses its confidential status
hereunder so long as neither the Sellers nor its Affiliates directly or
indirectly cause such information to enter the public domain.

         The Sellers acknowledge that the restrictions contained in this Section
6.6 are reasonable and necessary to protect the legitimate interests of the
Purchaser and that any breach by the Sellers of any provision of this Section
6.6 will result in irreparable injury to the Purchaser. The Sellers acknowledge
that, in addition to all remedies available at law, the Purchaser shall be
entitled to equitable relief, including injunctive relief, and an equitable
accounting of all earnings, profits or other benefits arising from any such
breach and shall be entitled to receive such other damages, direct or
consequential, as may be appropriate. The Purchaser shall not be required to
post any bond or other security in connection with any proceeding to enforce
this Section 6.6.

         Section 6.7 Reasonable Efforts; Further Assurances. Subject to the
terms and conditions herein provided, each of the parties hereto shall use all
reasonable efforts to take, or cause to be taken, all action, and to do, or
cause to be done, all things reasonably necessary, proper or advisable under
applicable laws and regulations to consummate and make effective the
transactions contemplated by this Agreement. Each of the Company, the Sellers
and the Purchaser will use all reasonable efforts to obtain consents of all
Governmental Authorities and third parties necessary to the consummation of the
transactions contemplated by this Agreement. In the event that at any time after
Closing any further action is necessary to carry out the purposes of this
Agreement or to obtain any licenses required, necessary or advisable in
connection with the operation of any of the Businesses, the Sellers or the
Purchaser, as the case may be, shall take all such action without any further
consideration therefor.

         Section 6.8  Third Party Proposals.

               6.8.1 Each of the Company, the U.S. Seller and the Canadian
Seller agrees that, during the term of this Agreement, it shall not, and shall
not authorize or permit any of its subsidiaries or any of its or its
subsidiaries' directors, officers, employees, agents or representatives to,
directly or indirectly, 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



                                      -50-
<PAGE>   51


or other business combination involving the Companies, or acquisition of any
capital stock from the Companies or any assets of the Companies in a transaction
outside of the Ordinary Course of Business, or any acquisition by any of the
Companies of any material assets or capital stock of any other person or any
combination of the foregoing (a "Competing Transaction"), or negotiate, explore
or otherwise engage in discussions with any person (other than the Purchaser, a
wholly-owned subsidiary of the Purchaser 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 terminate this Agreement or abandon, terminate or fail to consummate the
Closing or any other transactions contemplated by this Agreement; provided that,
at any time prior to the approval of the sale of the Stadtlander Shares by the
shareholders of the Canadian Seller, the Canadian Seller 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 the Canadian Seller 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 be inconsistent with the fiduciary duties
of the Board of Directors of the Canadian Seller under applicable laws and
determines that such a proposal is, after consulting with Donaldson, Lufkin and
Jenrette (or any other nationally recognized investment banking firm), more
favorable to the Canadian Seller's shareholders from a financial point of view
than the transactions contemplated by this Agreement (including any adjustment
to the terms and conditions proposed by the Purchaser in response to such
Competing Transaction). The Company and the Sellers 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 6.8.1, in the event that,
prior to the approval of the sale of the Stadtlander Shares to the Purchaser by
the shareholders of the Canadian Seller, the Board of Directors of the Canadian
Seller 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 be
inconsistent with the fiduciary duties of the Canadian Seller's Board of
Directors, the Board of Directors of the Canadian Seller may (subject to this
and the following sentences) withdraw, modify or change, in a manner adverse to
the Purchaser, its recommendation in favor of the transactions contemplated
hereby, provided that it uses all reasonable efforts to give the Purchaser two
calendar days prior written notice of its intention to do so (provided that the
foregoing shall in no way limit or otherwise affect the Purchaser's right to
terminate this Agreement pursuant to Section 8.1.14). The Canadian Seller's
Board of Directors shall not, in connection with any such withdrawal,
modification or change of its recommendation with respect to the transactions
contemplated hereby, take any action to change the approval of the Board of
Directors of the Canadian Seller for purposes of causing any takeover statute or
other law to be inapplicable to the transactions contemplated hereby, including
the Closing or the performance of the Support Agreements. From and after the
execution of this Agreement, the Company and the Sellers shall immediately
advise the Purchaser in



                                      -51-
<PAGE>   52


writing of the receipt, directly or indirectly, of any inquiries, discussions,
negotiations, or proposals relating to a Competing Transaction (including the
specific terms thereof and the identity of the other party or parties involved)
and furnish to the Purchaser 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, the Company and the Sellers shall immediately advise the Purchaser, in
writing, if the Board of Directors of the Canadian Seller shall make any
determination as to any Competing Transaction as contemplated by the proviso to
the first sentence of this Section 6.8.1.

               6.8.2 If, prior to the approval of the sale of the Stadtlander
Shares to the Purchaser by the shareholders of the Canadian Seller, the Board of
Directors of the Canadian Seller 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 the Canadian Seller or any of its
subsidiaries or Affiliates in violation of this Agreement, that failure to enter
into such Competing Transaction would be inconsistent with the fiduciary duties
of the Board of Directors of the Canadian Seller and that such Competing
Transaction is more favorable to the shareholders of the Canadian Seller 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 the Purchaser in response to such Competing Transaction)
and is in the best interest of the Canadian Seller's shareholders and the
Canadian Seller has received (x) the advice of its outside legal counsel as to
whether failure to enter into such a Competing Transaction would be inconsistent
with a breach of the Board of Directors' fiduciary duties and (y) advice from
Donaldson, Lufkin & Jenrette (or any other nationally recognized investment
banking firm) that the Competing Transaction is more favorable from a financial
point of view to the Canadian Seller's shareholders than the transactions
contemplated by this Agreement (including any adjustment to the terms and
conditions of such transaction proposed in writing by the Purchaser), the
Canadian Seller 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) the Canadian Seller has provided the
Purchaser with written notice that it intends to terminate this Agreement
pursuant to this Section 6.8.2, 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 the Canadian Seller has provided the notice
referred to in clause (i) above (provided that the advice referred to in clauses
(x) and (y) above shall continue in effect without revocation, revision or
modification), the Canadian Seller, as a condition to termination, delivers to
the Purchaser (A) a written notice of termination of



                                      -52-
<PAGE>   53


this Agreement pursuant to this Section 6.8.2 and (B) a certified or bank
cashier's check in the amount of twelve million dollars ($12,000,000).

         Section 6.9 Tax Election. The US Seller shall join with the Purchaser
in making an election under Sections 338(g) and 338(h)(10) of the Code (and any
corresponding elections under state, local or foreign tax law) (collectively, a
"338(h)(10) Election") with respect to the purchase and sale of the Stadtlander
Shares hereunder.

               6.9.1 The Purchaser shall determine the allocation of the Net
Purchase Price and the liabilities of the Companies (plus other relevant items)
to the assets of the Companies and shall furnish to the US Seller a schedule
(the "Allocation Schedule") setting forth that allocation. Neither the Purchaser
nor the US Seller shall take any action or any position that is inconsistent
with the Allocation Schedule on any Tax return or in any administrative or
judicial proceeding.

               6.9.2 The Purchaser and the US Seller shall on a timely basis
file all forms required under federal, state, local or foreign law to effect the
338(h)(10) Election (including IRS Form 8023), which forms shall be prepared
consistently with the Allocation Schedule.

               6.9.3 At the Closing, the Purchaser shall pay to the US Seller
the sum of twenty eight million dollars ($28,000,000) as consideration for the
US Seller's joining with the Purchaser in making the 338(h)(10) Election.

               6.9.4 Notwithstanding any other provisions of this Section 6.9,
the US Seller will be responsible for paying any Taxes attributable to the
making of the 338(h)(10) Election and the Sellers will indemnify and hold
harmless the Purchaser and the Companies against any costs arising out of any
failure to pay such Taxes.

         Section 6.10 Hart-Scott-Rodino Filings. Each of the Purchaser, the
Company and the Sellers will use all reasonable efforts to file with the
Antitrust Division of the Department of Justice (the "Antitrust Division") and
the Federal Trade Commission (the "FTC") within five Business Days after the
date hereof the notification and report form (the "Report") required under the
HSR Act with respect to the transactions contemplated hereby. Each of the
Company, the Sellers and the Purchaser shall cooperate with each other to the
extent necessary to assist each other in the preparation of its Report, shall
request early termination of the waiting period required by the HSR Act and, if
requested, will promptly amend or furnish additional information thereunder if
requested by the Antitrust Division and/or the FTC.

         Section 6.11 Notification by the Purchaser. The Purchaser shall
promptly inform the Sellers in writing if, prior to the consummation of the
Closing, any of the representations and warranties contained in Article V cease
to be accurate and complete.



                                      -53-

         Section 6.12 Agreements. At the Closing, the Purchaser and the Canadian
Seller shall (and shall cause its subsidiaries to) execute and deliver the
Voting Trust Agreement and make all deliveries required thereunder and the
Canadian Seller shall (and shall cause its subsidiaries to) execute and deliver
the Proxy and the Back-Up Option Agreement.

         Section 6.13  Company Options.

               6.13.1 The following terms shall have the following meanings:

               6.13.1.1 "Total Price" means (a) $300,000,000 plus (b) the
aggregate amount of cash payable to the Company upon the exercise in full of all
Stock Options outstanding immediately prior to the consummation of the Closing
plus (c) the amount, if any, by which the Certified Net Debt is less than
$100,000,000 plus (d) the Stock Appreciation Figure minus (e) the amount, if
any, by which the Certified Net Debt is greater than $100,000,000. For purposes
of this Agreement, the term "Stock Appreciation Figure" shall mean 3,022,670
(representing $150,000,000 divided by $49.625) multiplied by the extent, if any,
by which the Market Value exceeds $49.625; provided, however, that such $49.625
amount, the Market Value and such 3,022,670 number shall be equitably adjusted
hereunder as necessary to reflect the Stock Split if, on the date that any
determination of Market Value is made hereunder, the last sale price, quoted
regular way, of the BBC Common Stock reflects the Stock Split. It is understood
that the Stock Appreciation Figure shall be zero in the event that the Market
Value (as equitably adjusted for the Stock Split) is less than or equal to
$49.625 (as equitably adjusted for the Stock Split).

               6.13.1.2 "Fully Diluted Number" means the sum of (i) the
aggregate number of shares of Stadtlander Common Stock outstanding on the
Closing Date plus (ii) the aggregate number of shares of Stadtlander Common
Stock covered by subscriptions, options, rights, warrants, convertible
securities or other agreements or commitments to issue, or contracts or any
other agreements obligating the Company to issue, or to transfer from treasury,
any shares of Stadtlander Common Stock, or securities convertible into any such
shares, which options, warrants or other rights are outstanding immediately
prior to the consummation of the Closing.

               6.13.1.3 "Share Price" means the "Total Price" divided by the
Fully Diluted Number.

               6.13.1.4 "Stock Option" means an option to purchase one or more
shares of Stadtlander Common Stock pursuant to the Company's 1996 Incentive and
Non-qualified Stock Option Plan for Key Personnel and Directors or pursuant to
any other plan or agreement approved by the Board of Directors of the Company;
provided, however, that the exercise price of such option is the same for each
share of



                                      -54-
<PAGE>   55


Stadtlander Common Stock covered thereby. Accordingly, a Person who owns stock
options to purchase Stadtlander Common Stock at more than one exercise price
shall be deemed to own one Stock Option for each separate exercise price.

               6.13.1.5 "Optionee" shall mean each Person who owns one or more
Stock Options immediately prior to the Closing. "Designated Optionee" shall mean
each of Allan Silber, Morris Perlis, James Sas and Gordon Vanscoy.
"Non-Designated Optionee" shall mean each Optionee other than the Designated
Optionees.

               6.13.1.6 "Aggregate Appreciation" for an Optionee means, for each
Stock Option held by such Optionee immediately prior to the Closing, (a) the
amount by which the Share Price exceeds the exercise price of such Stock Option,
multiplied by (b) the number of shares of Stadtlander Common Stock covered by
such Stock Option.

               6.13.2 Prior to the Closing, the Company shall enter into
Designated Optionee Option Cancellation Agreements with each of the Designated
Optionees and Non-Designated Optionee Option Cancellation Agreements with each
of the Non-Designated Optionees. Each of the Option Cancellation Agreements
shall provide that (a) concurrent with the Closing, the Company shall pay to the
applicable Optionee, in cash, a dollar amount equal to such Optionee's Aggregate
Appreciation for each of such Optionee's Stock Options and (b) upon receipt of
such payment, all of such Designated Optionee's Stock Options shall be canceled.

         Section 6.14 Retained Employees. It is understood that on and after the
Closing, Allan Silber, Morris Perlis and James Sas (the "Retained Employees")
shall cease to be employees of the Companies and shall become, or continue to
be, employees of the Sellers. The Sellers agree that, subject to the terms of
the Transitional Consulting Agreements, the Sellers shall assume, and shall
indemnify the Companies against, all liabilities arising after the Closing with
respect to the post-Closing employment of the Retained Employees, including
without limitation all liabilities arising under any employment agreement or
employment benefit plan applicable to any of the Retained Employees. Concurrent
with the execution of this Agreement, the Purchaser and the Retained Employees
have entered into transitional consulting agreements in the form and substance
of the agreements annexed hereto as Appendix 6.14 (the "Transitional Consulting
Agreements"). For the first thirty (30) days after the Closing, the Sellers
shall make James Sas available to the Companies as a consultant on an as
requested basis for up to fifty percent (50%) of James Sas' work week. For the
next one hundred and fifty (150) days thereafter, the Sellers shall make James
Sas available to the Companies on an as requested basis for up to twenty percent
(20%) of James Sas' work week. The Purchaser shall cause the Company to
reimburse the Sellers for work performed by James Sas at the Company's request
at a rate of $130 per hour. In the performance of such work, James Sas shall be
employed as an employee of one or both of the Sellers and shall be designated by
the Sellers to provide



                                      -55-
<PAGE>   56


consulting services to the Purchaser in accordance with this Section 6.14.

         Section 6.15 PharMerica Shares. The Canadian Seller agrees as follows
with respect to the PharMerica Shares that it and its subsidiaries now or may
hereinafter beneficially own or otherwise hold (the "Subject PharMerica
Shares"):

               6.15.1 Without the prior written consent of the Purchaser, until
December 31, 1999, the Canadian Seller will not (and will not permit its
subsidiaries to), directly or indirectly, offer, sell, pledge (other than the
pledge existing on the date hereof, which pledge does not preclude the Canadian
Seller or its Subsidiaries from voting any Subject PharMerica Shares), transfer,
contract to sell, grant any option to purchase or otherwise dispose of any
Subject PharMerica Shares or any securities convertible into, derivative of or
exercisable or exchangeable for any Subject PharMerica Shares, provided,
however, that this Section 6.15.1 shall not prohibit the Canadian Seller from
distributing Subject PharMerica Shares to its shareholders as a dividend at any
time after December 25, 1999 and shall not prohibit the Canadian Seller or its
subsidiaries from selling the Subject PharMerica Shares pursuant to Section
6.15.2 at any time. At or prior to the Closing, the Canadian Seller shall (and
shall cause each of its subsidiaries that then owns PharMerica Shares to) use
its best efforts to cause the stock certificates representing the Subject
PharMerica Shares to be legended, in a manner reasonably satisfactory to the
Purchaser, to reflect the restrictions set forth in this Section 6.15.

               6.15.2 In the event that the Canadian Seller or any of its
subsidiaries receives, and desires to accept, a Bona Fide Offer from a
third-party (an "Offeror") to purchase for consideration any of the Subject
PharMerica Shares, the Canadian Seller will (or will cause its subsidiaries to)
promptly deliver to the Purchaser written notice of the intended disposition
(the "Disposition Notice") and the basic terms and conditions of the proposed
disposition, including the identity of the Offeror. The Purchaser will have the
right, exercisable upon written notice to the Canadian Seller within ten (10)
Business Days after receipt of the Disposition Notice, to purchase the Subject
PharMerica Shares covered by such Bona Fide Offer on the same terms and
conditions as those set forth in the Disposition Notice. The Canadian Seller
will not (and will cause its subsidiaries not to) sell any of such Subject
PharMerica Shares to the Offeror unless and until either (i) the Purchaser
notifies the Canadian Seller (or its subsidiaries, if applicable) that the
Purchaser does not intend to meet the terms set forth in the Disposition Notice
or (ii) the Purchaser fails to advise the Canadian Seller (or its subsidiaries,
if applicable) in writing, prior to the expiration of such ten (10) Business Day
period, that the Purchaser agrees to purchase such Subject PharMerica Shares on
the terms set forth in the Disposition Notice. In the event that the Purchaser
advises the Canadian Seller (or its subsidiaries, if applicable) of such
agreement within such ten (10) Business Day period, the Canadian Seller will (or
will cause its subsidiaries to) sell to the Purchaser, and the Purchaser will
purchase from the Canadian Seller (or its subsidiaries, if applicable), the
Subject PharMerica Shares covered by the Bona Fide




                                      -56-
<PAGE>   57


Offer upon the terms and conditions set forth in the Disposition Notice at a
closing to be held on the later of (x) the fifth Business Day after the Canadian
Seller's (or its subsidiaries', if applicable) receipt of notice of acceptance
from the Purchaser or (y) the second Business Day after the parties to such
closing shall have received all regulatory approvals necessary to consummate
such closing. If the Purchaser does not elect to purchase such Subject
PharMerica Shares, the Canadian Seller (or its subsidiaries, if applicable) will
be permitted to sell such Subject PharMerica Shares to the Offeror upon the
terms and conditions set forth in the Disposition Notice. If such sale is not
consummated within 120 calendar days of the mailing of the original Disposition
Notice, the procedures of this paragraph shall be followed again. For purposes
of this Agreement, the term "Bona Fide Offer" shall mean a bona fide offer to
acquire some or all of the Subject PharMerica Shares, provided that (x) the
Offeror is not an Affiliate of the Canadian Seller, (b) if the offer is a cash
offer, such offer is fully financed, (c) if the offer is not a cash offer, it is
an offer of marketable securities having a readily ascertainable market and (d)
the offer is not subject to any conditions other than conditions, if any,
imposed pursuant to the HSR Act. The provisions of this Section 6.15.2 shall
cease to apply on the sooner of (x) December 31, 1999 and (y) the first date on
which the Canadian Seller and its subsidiaries, having complied with this
Section 6.15, no longer beneficially own or otherwise hold any Subject
PharMerica Shares.

                  6.15.3 In the event that the shareholders of PharMerica are
asked to vote (either by vote, solicitation of proxies, solicitation of consents
or otherwise) with respect to a PharMerica Business Combination involving
PharMerica at any time prior to December 31, 2001, the Canadian Seller shall
(and shall cause its subsidiaries to) (a) notify the Purchaser that such vote is
being conducted promptly after the Canadian Seller is advised that such vote is
to be taken and (b) vote all of the Subject PharMerica Shares then owned by the
Canadian Seller in accordance with the Purchaser's written instructions if the
Purchaser provides the Canadian Seller and such subsidiaries with such
instructions prior to the date of the meeting of Party's shareholders or the
date three (3) Business Days prior to the last date on which consents may be
submitted. The provisions of this Section 6.15.3 shall terminate as to Subject
PharMerica Shares transferred or distributed in accordance with Sections 6.15.1
or 6.15.2 upon such transfer or distribution.

         Section 6.16 Environmental Matters. Prior to the Closing, the Purchaser
shall have the right, at its expense, to make such environmental studies of each
of the premises at which the Companies perform the Businesses (the "Premises"),
including reviewing records, inspecting the properties and testing the air,
subsoil, groundwater and building materials at the Premises, as it shall deem
necessary to determine whether the Premises are in compliance with all
applicable Environmental Laws and whether any Regulated Substances are present
at the Premises, but shall indemnify and hold the Companies harmless from any
loss, cost or damage proximately caused by such inspection. Such inspection
shall be scheduled and performed so as not to



                                      -57-
<PAGE>   58


unreasonably interfere with the Companies' business.

         Section 6.17 Canadian Seller's Shareholders' Meeting.

               6.17.1 The Canadian Seller shall take all action in accordance
with all applicable laws necessary to convene a special meeting of the
shareholders of the Canadian Seller (the "Canadian Sellers' Shareholders
Meeting") to be held on the earliest practical date after the date hereof and
use its best efforts to obtain the consent and approval of the Canadian Seller's
shareholders with respect to the sale of the Stadtlander Common Stock pursuant
to this Agreement, including recommending approval of such sale.

               6.17.2 The Canadian Seller shall, as soon as is reasonably
practicable, prepare an information circular in accordance with all applicable
laws and regulations pertaining thereto (the "Information Circular") for review
by the Purchaser. Subject to the consent of the Purchaser (which shall not be
unreasonably withheld), the Canadian Seller shall prepare and file the
Information Circular with the requisite Canadian regulatory authorities as soon
as is reasonably practicable following receipt of comments from the Purchaser's
representatives and shall use all reasonable efforts to have the Information
Circular declared effective by the requisite Canadian regulatory authorities or
otherwise comply with all prerequisites to delivery of the Information Circular
to the Canadian Seller's shareholders and shall use all reasonable efforts to
comply with all applicable legal requirements with respect to the Information
Circular through the date of the Canadian Sellers' Shareholders Meeting. If, at
any time prior to the date of such meeting, the Canadian Seller shall obtain
knowledge of any information contained in or omitted from the Information
Circular that would require an amendment or supplement to the Information
Circular, the Canadian Seller will so advise the Purchaser in writing and will
promptly take such action, if any, as shall be required by law to amend or
supplement the Information Circular. Such Information Circular shall include the
Canadian Seller's Board Recommendation. The Canadian Seller 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
jurisdiction's securities laws in connection with the Canadian Seller's
Shareholders Meeting.

         Section 6.18 Payment of Certain Debt. Subsequent to the Closing, the
Purchaser shall cause the Companies to pay the debt of the Companies included
within the Net Debt as of the Closing Date, except that any such debt secured by
any assets of the Companies shall be paid contemporaneously with the Closing.
Pursuant to such obligation, the Purchaser shall cause the Company to pay,
contemporaneously with the Closing (to the extent that the debt is secured by
any assets of the Companies) or as soon as practicable after the Closing Date,
any such indebtedness owed by the Company to the Canadian Seller and, subject to
the next sentence hereof, any such indebtedness owed by the Company to any
financial institution ("Bank Debt").



                                      -58-
<PAGE>   59


Notwithstanding the foregoing, in the event that at least three Business Days
prior to the Closing, (a) the Canadian Seller advises the Purchaser that such
payment of any portion of the Bank Debt will result in the payment of
prepayment, breakage or other similar fees (which fees will be included as
liabilities in determining the Net Worth as of the Closing Date pursuant to
Section 2.5.3 if paid by any of the Companies), (b) the Canadian Seller advises
the Purchaser that the Canadian Seller is willing to assume all of the
Companies' obligations with respect to such portion of the Bank Debt upon
payment by the Company to the Canadian Seller of an amount equal to the
aggregate dollar amount of such obligations (limited to principal and interest
through the date of payment) as of the Closing Date (the "Fee-Related Bank
Debt") and (c) the lender of the Fee-Related Bank Debt provides the Company with
documentation, in form and substance satisfactory to the Purchaser, to the
effect that upon payment of the Fee-Related Bank Debt by the Company to the
Canadian Seller, (i) the Companies will be discharged from any and all liability
with respect to the Fee-Related Bank Debt (including, without limitation, any
obligation to pay any principal, interest or premium with respect to the
Fee-Related Bank Debt and any obligation to pay any prepayment, breakage or
similar fee) and (ii) such lender will release all liens, encumbrances and
security interests securing the payment of such Fee-Related Bank Debt with
respect to any assets or other property of the Companies, then, in lieu of
causing the Company to repay the Fee-Related Bank Debt, the Purchaser shall
cause the Company, contemporaneous with the Closing, to pay to the Canadian
Seller an amount equal to the Fee-Related Bank Debt, provided that at the time
of such payment the Companies shall receive such discharges and releases as the
Purchaser and the Company shall reasonably request. Any debt paid

               6.22.4 In the event that (i) the Purchaser disputes any aspect of
the Interim Audited Financial Statements on the basis that, in any respect, the
Interim Audited Financial Statements were not prepared in accordance with GAAP,
consistently applied, (ii) the Purchaser notifies the Sellers of such dispute or
disputes within fourteen (14) calendar days after the Purchaser's receipt of
such financial statements and (iii) the Purchaser and the Sellers are unable to
resolve such dispute or disputes within seven (7) calendar days after the
Purchaser delivers such notice to the Sellers, the Purchaser shall have the
right to refer such dispute or disputes to an independent accounting firm
mutually acceptable to the Purchaser and the Sellers (the "Audit Firm"). In the
event of such a referral, the Purchaser, the Sellers and the Company shall
cooperate with the Audit Firm in providing the Audit Firm with such information
as the Audit Firm shall reasonably request for purposes of resolving such
disputed items. The conclusions of the Audit Firm shall be binding upon the

respect to the representations made by the Company and the Sellers regarding the
Interim Balance Sheet and the Interim Income, Stockholders' Equity and Cash Flow
Statements and (b) the calculation of the Net Worth as of September 30, 1998. In
the event that any such dispute or disputes is or are referred by the Purchaser
to the Audit Firm, (a) the Closing shall not be held prior to the fifth Business
Day after the Audit Firm has delivered to the parties hereto its written report
with respect to the items in dispute and (b) the Outside Date shall be extended
by the number of calendar days that elapse from the date of such referral to the
sixth Business Day after such delivery has been made. The Sellers shall pay the
fees of its accountants, including without limitation the Accountants, and the
Purchaser shall pay the fees of the CPA to the extent that the CPA is involved,
in connection with the preparation and review of the Interim Audited Financial
Statements. The fees and disbursements of any Audit Firm retained pursuant to
the provisions of this Section 6.22 shall be borne one-half by the Purchaser and
one-half by the Sellers.

               6.22.5 For purposes of this Agreement, the term "September 30 Net
Worth" shall mean (x) the Net Worth reflected in the Interim Audited Balance
Sheet in the event that the Purchaser does not provide the notice referred to in
clause (ii) of Section 6.22.4, (y) the Net Worth as of September 30, 1998 that
the Purchaser and the Sellers shall agree upon in writing in the event that the
Purchaser provides the notice referred to in clause (ii) of Section 6.22.4 but
such agreement of the Purchaser and the Sellers is reached prior to the
resolution of any disputed matters by the Audit Firm pursuant to this Section
6.22 and (z) the Net Worth as of September 30, 1998 as determined by the Audit
Firm (which firm shall determine such Net Worth by combining its conclusions
with respect to all matters in dispute with the conclusions of the Sellers and
the Purchaser with respect to all matters not in dispute) in the event that the
Purchaser provides the notice referred to in clause (ii) of Section 6.22.4 and
the Purchaser and the Sellers are unable to agree upon the disputed matters
prior to the resolution of any disputed matters by the Audit Firm.

               Section 6.23 Waiver The Purchaser waives compliance by the
Sellers with all

the date set for the Closing or in the event that the Purchaser reasonably
determines that any such condition cannot possibly be satisfied prior to the
Outside Date;

               8.1.10 by the Sellers, in the event that the conditions to their

               8.1.13 by the Canadian Seller pursuant to Section 6.8.2;

Seller determines, and the Purchaser concurs (such concurrence not to be
unreasonably withheld), that the number of shares of the Canadian Seller's
capital stock for which dissenters' rights have been exercised in connection
with the Canadian Seller's Shareholders' Meeting is so substantial as to
materially adversely affect the Canadian Seller's financial condition.

         Section 8.2  Effect of Termination

liability on the part of any party or its directors, officers or stockholders.
Notwithstanding the foregoing, nothing in this Section 8.2 shall relieve any

intentional breach of this Agreement, then, in addition to other remedies at law

pursuant to Sections 6.8.2 and 8.1.13;

                     8.2.2.2 the Purchaser terminates this Agreement pursuant to
Section 8.1.12 or 8.1.14;

                     8.2.2.3 (A) the Purchaser or the Canadian Seller terminates

the case of a termination by the Canadian Seller as described in Section
8.2.2.1, concurrently with such termination, (Y) in the case of a termination by
the Canadian Seller as described in Section 8.2.2.4 upon the earlier of a

with respect thereto if either such consummation or such execution occurs within
twelve months after such termination by the Canadian Seller, or (Z) in the case
of a termination by the Canadian Seller or the Purchaser as described in Section
8.2.2.3 where a Competing Transaction has been publicly announced or publicly
disclosed prior to the Canadian Seller's Shareholders Meeting (including any
adjournment or postponement thereof), prior to the earlier consummation of a

Canadian Seller will pay to the Purchaser in cash by wire transfer in
immediately available funds to an account designated by the Purchaser the sum of
twelve million dollars ($12,000,000), inclusive of the Purchaser's costs. For
purposes of this Agreement, "Business Combination" means (i) a merger,
consolidation, share exchange, business combination or similar transaction
involving any of the Companies or either of the Sellers as a result of which



                                      -70-
<PAGE>   71


the shareholders thereof reduce their percentage ownership interest in the

               9.2.4 The Sellers' indemnification obligations contained in
Sections 9.2.1(i), 9.2.1(iii) and 9.2.1(iv) hereunder shall not apply to any

9.2.1(iii)and 9.2.1(iv) hereunder shall apply to the total amount in excess of
$2,000,000, subject to a maximum liability to the Purchaser of $25,000,000 for

               9.2.5 The provisions of Article IX shall constitute the sole and
exclusive remedy of any Indemnified Party for Damages arising out of, resulting
from or incurred in connection with any inaccuracy in any representation or the
breach of any warranty made by the Purchaser, the Company or the Sellers in this
Agreement.

                  Section 9.3 Procedures for Third Party Claims. In the case of
any claim for indemnification arising from a claim of a third party (a "Third
Party Claim"), an Indemnified Party shall give prompt written notice to the
Indemnifying Party of any claim or demand of which such Indemnified Party has
knowledge and as to which it may request indemnification hereunder. The
Indemnifying Party shall have the right to defend and to direct the defense
against any such Third Party Claim, in its name or in the name of the
Indemnified Party, as the case may be, at the expense of the Indemnifying Party,
and with counsel selected by the Indemnifying Party unless (i) such Third Party
Claim seeks an order, injunction or other equitable relief against the
Indemnified Party, or (ii) the Indemnified Party shall have reasonably concluded
that (x) there is a conflict of interest between the Indemnified Party and the
Indemnifying Party in the conduct of the defense of such Third Party Claim or
(y) the Indemnified Party has one or more defenses not available to the
Indemnifying Party. Notwithstanding anything in this Agreement to the contrary,
the Indemnified Party shall, at the expense of the Indemnifying Party, cooperate
with the Indemnifying Party, and keep the Indemnifying Party fully informed, in
the defense of such Third Party Claim. The Indemnified Party shall have the
right to participate in the defense of any Third Party Claim with counsel
employed at its own expense; provided, however, that, in the case of any Third
Party Claim described in clause (i) or (ii) of the second preceding sentence or
as to which the Indemnifying Party shall not in fact have employed counsel to
assume the defense of such Third Party Claim, the reasonable fees and
disbursements of such counsel shall be at the expense of the Indemnifying Party.
The Indemnifying Party shall have no indemnification obligations with respect to
any Third Party Claim which shall be settled by the Indemnified Party without
the prior written consent of the



                                      -73-
<PAGE>   74


Indemnifying Party, which consent shall not be unreasonably withheld or delayed.

         Section 9.4 Procedures for Inter-Party Claims. In the event that an
Indemnified Party determines that it has a claim for Damages against an
Indemnifying Party hereunder (other than as a result of a Third Party Claim),
the Indemnified Party shall give prompt written notice thereof to the
Indemnifying Party, specifying the amount of such claim and any relevant facts
and circumstances relating thereto. The Indemnified Party shall provide the
Indemnifying Party with reasonable access to its books and records for the
purpose of allowing the Indemnifying Party a reasonable opportunity to verify
any such claim for Damages. The Indemnified Party and the Indemnifying Party
shall negotiate in good faith regarding the resolution of any disputed claims
for Damages. Promptly following the final determination of the amount of any
Damages claimed by the Indemnified Party, the Indemnifying Party shall pay such
Damages to the Indemnified Party by wire transfer or check made payable to the
order of the Indemnified Party, without interest. In the event that the
Indemnified Party is required to institute legal proceedings in order to recover
Damages hereunder, the cost of such proceedings (including costs of
investigation and reasonable attorneys' fees and disbursements) shall be added
to the amount of Damages payable to the Indemnified Party.

         Section 9.5 Intentionally omitted.

         Section 9.6 Limitations Arising from Knowledge of Claims.
Notwithstanding any provision herein to the contrary, neither the Sellers nor
the Purchaser shall be entitled to indemnification with respect to any claim
under either Section 9.2.1(i) or 9.2.2(i) in the event that the party seeking
indemnification had knowledge of the substance and approximate magnitude of such
claim prior to the Closing.

of Directors (or executive committees thereof), at any time before or after

hereto.

         Section 10.9 Publicity. Unless otherwise required by applicable laws or

Hooper, James Sas, Gordon Vanscoy, Michele Law, Trey Hartman, Sean Creehan,

Collis, Eric Schmitt and Donna Dolan.

         Section 10.14 Subsidiaries' Ownership of PharMerica Shares. To the

actions with respect to its subsidiaries' conduct relating to the

______________ , 1998




Bergen Brunswig Corporation
4000 Metropolitan Drive
Orange, CA  92868


RE:      IRREVOCABLE PROXY FOR PHARMERICA SHARES

Gentlemen:

         We refer to that certain Stock Purchase Agreement, dated as of November
8, 1998 (the "Stock Purchase Agreement"), by and among Bergen Brunswig
Corporation, a New Jersey corporation ("BBC"), Stadtlander Drug Co., Inc., a
Pennsylvania corporation ("Stadtlander"), Counsel Corporation, an Ontario
corporation (the "Canadian Seller"), and Stadt Holdings, Inc., a Delaware
corporation and an indirect subsidiary of the Canadian Seller (the "U.S. Seller"
and, collectively with the Canadian Seller, the "Sellers"). All capitalized
terms not otherwise defined herein shall have the meanings ascribed thereto in
the Stock Purchase Agreement.

         This letter is being delivered pursuant to Section 6.15 of the Stock
Purchase Agreement to evidence the voting rights we have granted to BBC with
respect to the PharMerica Shares now owned and hereafter acquired by us, subject
to our right to dispose of our PharMerica Shares in accordance with Section 6.15
of the Stock Purchase Agreement. We reiterate our acknowledgment that as a
material inducement and condition to your willingness to enter into the Stock
Purchase Agreement, you have requested, and the Sellers have agreed (on behalf
of themselves and their subsidiaries) under Section 6.15 of the Stock Purchase
Agreement to grant to you, an irrevocable proxy to vote the PharMerica Shares in
any and all votes by the stockholders of PharMerica in a vote to approve or
disapprove a PharMerica Business Combination (a "PharMerica Business Combination
Vote"), subject to our right to dispose of our PharMerica Shares in accordance
with Section 6.15 of the Stock Purchase Agreement.

         In fulfillment of our agreement as aforesaid, we have executed and
attached to this letter an irrevocable proxy (the "Proxy") appointing BBC as
proxy, with full power of substitution, to vote in a PharMerica Business
Combination Vote all of the PharMerica Shares owned by the undersigned as of the
record date for such vote, as and to the extent BBC shall determine in its sole
discretion. We further acknowledge that the Proxy is coupled with an interest in
the subject PharMerica Shares by reason of the rights granted to BBC therein
under the Stock Purchase Agreement.

         The Proxy is irrevocable, and shall not be terminated, revoked, amended
or modified in any way except by a writing signed by BBC and the undersigned.
This letter agreement, together with the Proxy and the Stock Purchase Agreement,
contains the entire agreement of the parties with respect to the subject matter
hereof. The undersigned acknowledge and agree that monetary damages are an
inadequate remedy for breach of the Proxy. Therefore, the undersigned agree that
BBC has the right and shall be entitled to, in addition to any other rights it
may have, specific enforcement of the Proxy. Each of the undersigned hereby
further agree that it shall do all things, take all steps, including without
limitation, executing all further documents, instruments, powers and agreements
to further the intent and purposes of this letter agreement and to confer upon
BBC the practical benefits to be realized by it hereunder.

step, to revoke this Proxy or otherwise diminish or prevent the practical
realization of the rights granted to BBC hereunder, subject to the undersigned's

deliver this Proxy, and when so executed, this Proxy shall remain valid and in

                          W I T N E S S E T H T H A T:

        WHEREAS, the Canadian Seller, the Purchaser, Stadtlander Drug Co., Inc.,

has agreed, under 


<PAGE>   2


Section 6.15 of the Stock Purchase Agreement, that the Canadian Seller and its
subsidiaries shall grant to the Purchaser an irrevocable option to purchase the
PharMerica Stock in accordance with the conditions set forth herein;

        WHEREAS, all of the PharMerica Shareholders' shares of PharMerica Stock
have been delivered to and deposited with the Purchaser as the voting trustee
(the "Voting Trustee") under that certain Voting Trust Agreement, dated
__________, 199 , by and among the parties hereto (the "Voting Trust");

        WHEREAS, each of the PharMerica Shareholders have granted to the Voting
Trustee an irrevocable proxy authorizing the Purchaser to vote the PharMerica
Stock in certain circumstances (the "Proxy");

        WHEREAS, each of the parties hereto believes it to be in their
respective best interests to set forth the terms of their respective
understandings with respect to the option described herein and the matters
related thereto as hereinafter provided.

        NOW, THEREFORE, in consideration of the foregoing premises, the mutual
covenants herein contained and other good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged, the parties hereto,
intending to be legally bound, hereby agree as follows:

        Section 1. Grant of Option. On and subject to the terms and conditions
in this Agreement, each of the PharMerica Shareholders hereby grants to the
Purchaser the irrevocable option to purchase (the "Option") all of the shares of
PharMerica Stock then owned by such PharMerica Shareholder at the time the
Purchaser gives an Exercise Notice (as defined below) to such Shareholder. The
Option shall expire at 11:59 p.m. Eastern Standard Time, on December 31, 2001
(the "Expiration Time") and, prior to the Expiration Time, shall cease to apply
(at the time of disposition) to any shares of PharMerica Stock that are disposed
of by the PharMerica Shareholders in accordance with Section 6.15 of the Stock
Purchase Agreement.

        Section 2. Terms Governing Exercise of Option. (a) The Option may be
exercised, in whole or in part, from time to time, during the period commencing
simultaneously with the occurrence of a Triggering Event (as defined below) and
ending at the Expiration Time. In order to exercise the Option, the Purchaser
shall give written notice (an "Exercise Notice") to the PharMerica Shareholders
from whom it elects to acquire PharMerica Stock, specifying the number of shares
of PharMerica Stock it elects to purchase, the date on which such purchase shall
occur (which may be the date on which such notice is given) (the "Closing Date")
and the outcome of the vote at the Business Combination Meeting (as defined
below) that it desires to result. The parties hereto acknowledge that a
Triggering Event may occur as late as the day on which the Purchaser desires to
be the owner of some or all of the PharMerica Stock subject to this Agreement,
and therefore, an Exercise Notice given on the same date specified for Closing

<PAGE>   3

purposes of giving an Exercise Notice, provided that such notice is actually
received by the PharMerica Shareholders. It is further understood and agreed
that the Closing Date specified in an Exercise Notice need not be a date
certain, but may be a day, date or number of days related to another date
certain. By way of example and not in limitation, an Exercise Notice may provide
that a Closing shall occur on the business day immediately before a specifically
scheduled meeting of the shareholders of PharMerica.

        (b) Certain Definitions. The following terms shall have the meanings
ascribed thereto for the purposes of this Agreement:

        (i) The "Purchase Price" for the purchase of PharMerica Stock pursuant
to this Agreement shall equal the product (rounded to the nearest penny) of (x)
the number of shares of PharMerica Stock specified for purchase in an Exercise
Notice, multiplied by (y) 110% of the average closing price for one share of
PharMerica Stock (subject to appropriate adjustments for splits, dividends or
other subdivisions or combinations) for the last ten (10) Trading Days ending
three (3) Trading Days immediately prior to the Closing Date.

        (ii) A "Trading Day" shall mean a day on which the PharMerica Stock is
traded in the NASDAQ National Market or other exchange or quotation service on
which the PharMerica Stock is traded.

        (iii) The "Closing" shall be the closing of the purchase of the
PharMerica Stock specified in the Exercise Notice for which such Exercise Notice
is given.

        (iv) A "Triggering Event" shall mean the occurrence of (x) and (y) in
any order:

               (x) the announcement of, or the giving of notice for, a meeting
        (a "Business Combination Meeting") of the PharMerica Shareholders to
        vote on (exclusively or non-exclusively) a PharMerica Business
        Combination (as defined in the Stock Purchase Agreement); and

               (y) the first to occur of any one or more of the following
        events: (1) the filing or commencement by any party other than the
        Purchaser (or an "affiliate", as that term is defined in Rule 12b-2 of
        the Rules and Regulations promulgated under the Securities Act of 1934,
        as amended (the "'34 Act"), of the Purchaser) of an action, suit or
        proceeding, to interpret, construe, overturn, invalidate, block, suspend
        or otherwise impede the enforceability of, or the exercise of the
        Purchaser's rights under, (A) any proxy relating to the PharMerica Stock
        given at any time by any of the PharMerica Shareholders to the
        Purchaser, including without limitation, the Proxy (a "Shareholder's
        Proxy"), or (B) the Voting Trust; or (2) the revocation or attempted
        revocation of any Shareholder's Proxy or the Voting Trust, including
        without limitation, the delivery of any notice to the Purchaser in
        respect of any such Shareholder's Proxy or the Voting Trust with 


                                      -3-
<PAGE>   4


        the intent or effect to revoke such Shareholder's Proxy or the Voting
        Trust, or any other act (by any party other than the Purchaser) that has
        the intended or unintended effect of revoking a Shareholder's Proxy or
        the Voting Trust; or (3) the breach of, default of or other failure to
        comply with or failure to perform any material term or condition by any
        party other than the Purchaser of any Shareholder's Proxy, the Voting
        Trust or Section 6.15 of the Stock Purchase Agreement.

        (v) A "Prohibiting Event" shall mean (x) any judgment, order or ruling

PharMerica Business Combination or a Business Combination Meeting; or (y) the
receipt of an opinion of the Canadian Seller's counsel that the purchase of
PharMerica Stock contemplated by the applicable Exercise Notice cannot be
consummated unless further action is taken under or in connection with the HSR
Act (as defined herein).

        (c) Closing. On the Closing Date, unless there shall then be in effect a
Prohibiting Event, the Closing shall occur and (i) each PharMerica Shareholder
receiving an Exercise Notice (a "Selling Shareholder") shall sell, transfer,
convey, assign and deliver unto the Purchaser, all of such PharMerica
Shareholder's right, title and interest in and to the shares of PharMerica Stock
specified for purchase in such Exercise Notice together with an irrevocable
proxy appointing the Purchaser to vote such PharMerica Stock in the manner
determined by the Purchaser in its sole discretion, and (ii) the Purchaser shall
purchase and acquire all such right, title and interest in and to such shares of
PharMerica Stock. In consideration of the aforesaid sale, transfer, conveyance,
assignment and delivery, the Purchaser shall deliver or cause to be delivered to
each Selling Shareholder the Purchase Price for the PharMerica Stock acquired
from such Selling Shareholder in immediately available funds by wire transfer to
a bank account designated by such Selling Shareholder at or before the Closing,
or by certified check to such Selling Shareholder at the Closing. If a
Prohibiting Event shall occur and prevent the occurrence of a Closing under this
Section 2(c), then, subject to Section 3(b), at the Purchaser's election, the
Closing shall either (a) be postponed until such time as the Purchaser shall
determine in its sole discretion, but in no event sooner than the first date on
which there would no longer be a Prohibiting Event in effect and in no event
later than the Expiration Time, or (b) be canceled. No Closing shall occur with
respect to the PharMerica Stock that is disposed of prior to the Closing Date in
accordance with Section 6.15 of the Stock Purchase Agreement.

        (d) Transfer Documents. The sale of the PharMerica Stock pursuant to
this Agreement shall be effected by the delivery at the Closing by each Selling
Shareholder to the Purchaser (i) as the Voting Trustee (or the current successor
thereto) under the Voting Trust, if it be such and if the Shares of PharMerica
Stock are held in the Voting Trust at that time, of written authorization to
release from the Voting Trust and deliver to the Purchaser in its corporate
capacity, and not as Voting Trustee, the shares of PharMerica Stock then
purchased hereunder by the Purchaser, (ii) of an irrevocable 


                                      -4-
<PAGE>   5

proxy appointing the Purchaser to vote the PharMerica Stock, in the form of the
proxies set forth in Exhibits A-1 and A-2, as applicable, annexed hereto and
made a part hereof, and (iii) of such other appropriate instruments of sale,
transfer, conveyance, assignment and delivery, including without limitation,
stock powers duly endorsed in blank, powers of attorney, and instructions to any
applicable voting trustee then holding such shares in trust, and such other
documents and instruments as the Purchaser may reasonably require to effect the
sale, transfer, conveyance, assignment and delivery of such shares.

        Section 3.    Conditions and Covenants.

        (a) HSR. The parties acknowledge that (i) depending upon the number of
shares of PharMerica Stock to be acquired pursuant to the terms of a particular
Election Notice, the consummation of a Closing may be precluded until such time
as the requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
as amended (the "HSR Act"), are satisfied, (ii) Purchaser will pay any filing
fees associated with such HSR Act filing.

        (b) Rescission. The sale, transfer, conveyance, assignment and delivery
to the Purchaser of the PharMerica Stock pursuant to Section 2(c) may be
rescinded by the PharMerica Shareholders or the Purchaser if either of the
following events occur: (i) the PharMerica Stock acquired pursuant to Section
2(c) is voted at the Business Combination Meeting in accordance with the last
written instructions delivered by the Purchaser to Canadian Seller at or before
the Business Combination Meeting; or (ii) the outcome of the vote at the
Business Combination Meeting is the intended outcome specified in the last
written instructions delivered by the Purchaser to Canadian Seller at or before
the Business Combination Meeting.

        (c) Subsequent Purchases. If the Purchaser (or any of its wholly owned
or majority owned subsidiaries) acquires shares of PharMerica Stock pursuant to
Section 2(c) and, during the Operative Period, acquires any other shares of
PharMerica Stock at a price per share that is higher than the price per share
paid by the Purchaser pursuant to Section 2(c) (the "Exercise Price"), the
Purchaser shall pay to the PharMerica Shareholders an amount equal to the
Differential Price multiplied by the number of shares of PharMerica Stock
acquired by the Purchaser pursuant to Section 2(c), such amount to be allocated
between the PharMerica Shareholders in proportion to the relative number of
shares of PharMerica Stock sold by each such entity pursuant to Section 2(c).
For purposes of this Section 3(c), (w) the term "Highest Price" shall mean the
highest price (excluding assumed liabilities and valuing any non-cash asset at
its fair market value, it being understood that any dispute with respect to such
fair market value shall be resolved by a valuation firm mutually acceptable to
the Purchaser and the PharMerica Shareholders) per share paid by the Purchaser
(or any of its wholly owned or majority owned subsidiaries) for any shares of
PharMerica Stock during the Operative Period, (x) the term "Differential Price"
shall mean the amount by which the Highest Price exceeds the Exercise Price, (y)
the term "Operative Period" shall mean 


                                      -5-
<PAGE>   6

the period commencing on the date hereof and expiring on the date that the
current term of the PharMerica/Purchaser Agreement terminates or expires and (z)
the term "PharMerica/Purchaser Agreement" shall mean the existing pharmaceutical
supply agreement between PharMerica and the Purchaser pursuant to which
PharMerica purchases pharmaceuticals on a wholesale basis from Purchaser.

        (d) Subsequent Sales. If the Purchaser (or any of its wholly owned or
majority owned subsidiaries) acquires shares of PharMerica Stock pursuant to
Section 2(c) and, during the Operative Period, sells any or all of such shares
(the "Sold Shares") to an individual or entity that is not affiliated with the
Purchaser at a price per share (excluding assumed liabilities and valuing any
non-cash asset at its fair market value, it being understood that any dispute
with respect to such fair market value shall be resolved by a valuation firm
mutually acceptable to the Purchaser and the PharMerica Shareholders) (such
price, the "Sale Price") that is greater than the Exercise Price, the Purchaser
shall pay to the PharMerica Shareholders (such payment to be allocated between
the PharMerica Shareholders in proportion to the relative number of shares of
PharMerica Stock sold by each such entity pursuant to Section 2(c)) an amount
equal to the amount, if any, by which the Stock Appreciation exceeds the Net
Carrying/Tax Costs. For purposes of this Agreement, (w) the term "Stock
Appreciation" shall mean the Profit multiplied by the number of Sold Shares, (x)
the term "Profit" shall mean the amount by which the Sale Price exceeds the
Exercise Price (or, if the Purchaser has paid to the PharMerica Shareholders any
amount pursuant to Section 3(c), the sum of the Exercise Price and the per share
amount paid by the Purchaser pursuant to Section 3(c)) and (y) the term
"Carrying/Tax Costs" shall mean the sum of (i) interest on the amount paid by
the Purchaser pursuant to Section 2(c), from the date of the Closing to the date
on which the Sold Shares are sold, at an implied interest rate equal to the
weighted average interest rate paid by the Purchaser on bank borrowings during
such period and (ii) all federal and state taxes payable by the Purchaser with
respect to the sale of the Sold Shares (provided that the Purchaser uses
commercially reasonable efforts to minimize its tax liability with respect to
such sale), and (z) the term "Net Carrying/Tax Costs" shall mean the difference
between the Carrying/Tax Costs and the amount of any dividends or distributions
paid by the Purchaser on the Sold Shares during the period from the date of the
Closing to the date they are sold.

        (e) Further Assurances. If the Purchaser exercises the Option and such
exercise is not rescinded pursuant to Section 3(b), from time to time
thereafter, each of the PharMerica Shareholders shall execute and deliver all
such further documents and instruments and take all such further action as may
be necessary in order to consummate the transactions contemplated hereby.

        Section 4. Specific Performance. Each of the PharMerica Shareholders
acknowledges and agrees that monetary damages are an inadequate remedy for
breach of this Agreement. Therefore, each PharMerica Shareholder agrees that the
Purchaser has the right and shall be entitled to, in addition to any other right
it may have, specific performance of this Agreement in the event of any such
breach.

Voting Trust, the Proxy and the Stock Purchase Agreement) constitutes the entire
agreement among the parties hereto pertaining to the subject matter hereof and
supersedes all other prior and contemporaneous agreements, understandings,
negotiations and discussions, whether oral or written, of the parties. There are
no other agreements between the parties in connection with the subject matter
hereof except as specifically set forth herein.

        Section 10. Governing Law; Consent to Jurisdiction. This Agreement shall
be governed by, and construed in accordance with, the internal laws of the State
of Delaware, without reference to the choice of law principles thereof. Each of
the parties hereto irrevocably submits to the exclusive jurisdiction of the

District of Delaware for the purpose of any suit, action, proceeding or judgment
relating to or arising out of this Agreement and the transactions contemplated

courts in which any suit, action or proceeding hereunder shall be brought.

        Section 11. Assignment; Successors and Assigns; No Third Party Rights.

                                  VOTING TRUST


     VOTING TRUST AGREEMENT, dated as of             , 1998, by and among
Counsel Corporation, an Ontario corporation (the "Canadian Seller"), Counsel
Healthcare Assets, Inc., a Delaware corporation ("CHA", and together with the
Canadian Seller, the "Stockholders"), and Bergen Brunswig Corporation, a New
Jersey corporation, its successors in trust, as voting trustee (in such
capacity, the "Voting Trustee").


                                    RECITALS

     WHEREAS, the Stockholders are the legal and beneficial owners of the number
of shares, indicated on Schedule 1 hereto, of common stock, par value $.01 (the

constitute on the day hereof, approximately 8% of the issued and outstanding
PharMerica Stock; and

     WHEREAS, the Canadian Seller, Bergen Brunswig Corporation, Stadtlander Drug
Co., Inc., a Pennsylvania corporation, and another subsidiary of the Canadian
Seller have entered into a certain Stock Purchase Agreement, dated as of
November 8, 1998 (the "Stock Purchase Agreement"), pursuant to which the 
Stockholders have agreed that the Voting Trustee shall be empowered to exercise 
the Stockholders' rights to direct the vote of their PharMerica Stock upon the 
circumstances described herein;

     NOW, THEREFORE, the parties hereto herby agree that a voting trust with
respect to the shares of PharMerica Stock now owned (or received as a dividend
on such shares) by each of the Stockholders is hereby created and established,
subject to the terms and conditions of this Agreement (the "Voting Trust"), and
further agree as follows:

     SECTION 1. Registration of Voting Trust Stock. Simultaneously with the
execution of this Agreement, the Stockholders shall deposit with the Voting
Trustee all of the shares of PharMerica Stock owned by each of them by delivery
to the Voting Trustee of certificates representing such shares of PharMerica
Stock, together with stock powers, duly endorsed in blank, transferring such
certificates to the Voting Trustee. The Voting Trustee is fully authorized to
take such action as is necessary to effect the transfer of such shares of
PharMerica Stock to, and in the name of, the Voting Trustee on the books of the
Corporation (and also to cause any further transfers of such shares to be made
which become necessary through any change of the entities holding the office of
Voting Trustee, as hereinafter provided). The Voting Trustee shall file
duplicates of this Agreement with the Secretary of the Corporation and the
registered office of the Corporation in the State of Delaware. The certificates

this Agreement shall be surrendered by the Voting Trustee to the Corporation and
canceled, and new certificates therefor shall be issued to and held by the 
Voting Trustee in the name of the Voting Trustee (in its capacity as such) 
(such shares of PharMerica Stock and any other shares of PharMerica Stock that 
may in the future be deposited in the voting Trust being referred to herein as 
the "Voting Trust Stock"). Upon receipt by the Voting Trustee of the 
certificates for such shares of PharMerica Stock and upon the transfer of such 
shares of PharMerica Stock into the name of the Voting Trustee, the Voting 
Trustee shall hold the Voting Trust Stock, as stockholder of record, subject to 
the terms and conditions of this Agreement. The Voting Trustee shall request 
the Corporation to state in the stock ledger of the Corporation that the shares 
of PharMerica Stock transferred or issued to the Voting Trustee were 
transferred or issued pursuant to this Agreement.

     SECTION 2.   Stock Certificates.   On all certificates representing Voting
Trust Stock, in addition to any other legend that may be required, the following
legend shall be appended:

     The shares of Common Stock evidenced by this stock certificate

   voting and on transfer, contained in the Voting Trust Agreement,
   dated as of _______________, 199_, among Counsel Corporation, 
   Counsel Healthcare Assets, Inc. and Bergen Brunswig Corporation, 
   as voting trustee, and are issued pursuant to such Voting Trust 
   Agreement. By accepting this stock certificate, the holder hereof
   agrees to be bound by all of the provisions of such Voting Trust 
   Agreement, which is available for inspection by the holder hereof
   daily at the registered office of the Corporation in the State of 
   Delaware during regular business hours.

     SECTION 3.   Issuance of Voting Trust Certificates.   The Voting Trustee
shall issue to each of the Stockholders, in exchange for the Voting Trust Stock
delivered hereunder, a voting trust certificate substantially in the form
attached as Exhibit A hereto (a "Voting Trust Certificate"). Except as otherwise
provided herein, all options, rights of purchase and other powers and privileges
affecting the Voting Trust Stock represented by a Voting Trust Certificate shall
attach to such Voting Trust Certificate.

     (a) The Voting Trustee shall have the exclusive right to exercise, in 
person or by its nominees or proxies or by written consent, all voting rights

the holders of the Voting Trust Certificates notify the Voting Trustee that 
such holder desires to offer, sell, pledge or transfer any shares of the Voting

Voting Trust Certificate has been destroyed, lost or stolen, and upon proof of 
ownership satisfactory to the Voting Trustee together with such security or

Trustee shall execute and deliver a new Voting Trust Certificate for the same 
number of shares of Voting Trust Stock as the Voting Trust Certificate so 
mutilated, destroyed, lost or stolen, with such notations, if any, as the 
Voting Trustee shall determine.

     (c) Prior to due presentment of a Voting Trust Certificate for transfer in 
compliance with the requirements of Section 5(a), the Voting Trustee may treat
