Item 4. Purpose of Transaction

         At  the  closing  described  in a  purchase  agreement  (the  "Purchase
Agreement"),  dated as of November 8, 1998, among the Reporting Person,  Counsel
Corporation (the "Canadian Seller"),  a wholly-owned  subsidiary of the Canadian
Seller (the "US Seller"),  and Stadtlander Drug Co., Inc.  ("Stadtlander"),  the
Reporting  Person will  acquire  100% of  Stadtlander.  Pursuant to the Purchase
Agreement and as a material  inducement and condition to the  willingness of the
Reporting Person to agree to the terms of the Purchase  Agreement,  the Canadian
Seller  agreed,  with respect to the shares of the Common  Stock of  PharMerica,
Inc. (the "Issuer") that it (and its subsidiaries)  currently  beneficially owns
or may in the future  beneficially  own or otherwise  hold (the "Subject  Issuer
Shares"),  that, from the date of such Purchase Agreement: (i) without the prior
written consent of the Reporting  Person,  until December 31, 1999, the Canadian
Seller (and its  subsidiaries)  will not dispose of any Subject  Issuer  Shares,
provided,  however,  that the  Purchase  Agreement  (a) does  not  prohibit  the
Canadian Seller (or its subsidiaries) from distributing Subject Issuer Shares to
its shareholders as a dividend at any time after December 25, 1999, and (b) does
not prohibit the Canadian Seller (or its subsidiaries)  from selling the Subject
Issuer  Shares  at any  time  pursuant  to the  procedures  described  below  in
connection with the right of first refusal granted to the Reporting Person; (ii)
in the event that the Canadian Seller (or any of its subsidiaries)  receives and
desires to accept an offer from a third party to purchase for  consideration any
of the  Subject  Issuer  Shares,  the  Canadian  Seller (or its  subsidiary,  as
applicable) is required to deliver to the Reporting Person written notice of the
intended  disposition  and  the  basic  terms  and  conditions  of the  proposed
disposition,  including the identity of the offering third party.  The Reporting
Person will have the right to purchase the Subject  Issuer Shares covered by the
offer on the same  terms  and  conditions  as set  forth in the  notice.  If the
Reporting  Person does not elect to  purchase  the Subject  Issuer  Shares,  the
Canadian  Seller (or its  subsidiary)  will be  permitted  to sell such  Subject
Issuer  Shares to the  offering  third party upon the terms and  conditions  set
forth in the notice.  After  December  31,  1999,  the  Canadian  Seller will be
permitted  to  dispose  of the  Subject  Issuer  Shares  without  providing  the
Reporting  Person with any right of first  refusal;  and (iii) in the event that
the  shareholders  of the  Issuer  are asked to vote with  respect  to an Issuer
Business  Combination (as defined below) at any time prior to December 31, 2001,
the  Canadian  Seller is required to (and is required to cause its  subsidiaries
to) (a) notify the Reporting Person that such a vote is being conducted, and (b)
vote all of the Subject  Issuer  Shares then owned by such parties in accordance
with the Reporting Person's written  instructions.  The rights described in this
clause (iii) above are  hereinafter  referred to as the "Limited Voting Rights".
Subject  Issuer  Shares  disposed of prior to December 31, 2001  pursuant to the
Purchase  Agreement  will cease to be subject to the Limited  Voting Rights upon
such disposition.  Under the Purchase Agreement,  an Issuer Business Combination
means (a) any merger,  consolidation,  share exchange,  business  combination or
similar transaction  involving the Issuer (other than a transaction in which the
shareholders  of the Issuer,  after such  transaction,  will  continue to own at
least 50.1% of the shares of the  successor  corporation  and the members of the
Board of  Directors  immediately  preceding  the  transaction  will  continue to
represent  at least a majority of the members of the Board of  Directors  of the
successor corporation),  (b) any sale, lease or transfer of substantially all of
the assets of the Issuer, (c) any tender or exchange offer made generally to the
shareholders of the Issuer and (d) any other transaction  which, if 

<PAGE>

consummated,  would be  required by the SEC to be reported in response to Item 1
of the Current Report on Form 8-K.

         The foregoing description of the Purchase Agreement is qualified in its
entirety by  reference to the  Purchase  Agreement,  a copy of which is attached
hereto as Exhibit 2.1 and incorporated by reference  herein.  In addition to the
rights  granted  to the  Reporting  Person  under the  Purchase  Agreement,  the
Purchase  Agreement  provides that at the Closing,  the Canadian Seller (and its
subsidiary)  will execute a voting trust agreement,  an irrevocable  proxy and a
back-up  option.  Pursuant to the voting  trust  agreement  (the  "Voting  Trust
Agreement"),  the  Reporting  Person  will be the Voting  Trustee for all of the
Subject  Issuer Shares,  which will be deposited with the Reporting  Person upon
the Closing.  The  certificates  representing  the Subject Issuer Shares will be
canceled and new certificates will be issued to and held by the Reporting Person
in the name of the Reporting Person.  All options,  rights of purchase and other
powers and  privileges of the Subject  Issuer Shares (other than voting  rights)
will attach to Voting Trust Certificates issued to the Canadian Seller (and such
subsidiary).  The Reporting  Person will not be entitled to retain any dividends
or distributions of cash or other property or securities relating to the Subject
Issuer Shares (other than dividends or distributions  made in Issuer stock which
will be held by the Reporting  Person under the Voting Trust  Agreement).  These
must be paid to the Canadian Seller (and its subsidiary). Under the Voting Trust
Agreement,  the  Reporting  Person  will vote the Subject  Issuer  Shares on all
matters in accordance with the written  instructions of the Canadian Seller (and
its  subsidiary)  or abstain if no  instructions  are given,  except that in the
event that the  shareholders  of the Issuer are asked to vote with respect to an
Issuer Business  Combination,  the Reporting Person will be entitled to vote the
Subject  Issuer Shares with respect to such vote in the manner and to the extent
that it determines in its sole discretion,  regardless of any instructions  that
may be given by the Canadian Seller (or its subsidiary).

         Under  certain  circumstances,  including  any  instance  in which  the
Canadian  Seller may transfer the Subject Issuer Shares pursuant to the Purchase
Agreement,  the  Canadian  Seller (and its  subsidiary)  may transfer the Voting
Trust  Certificates  with the consent of the Reporting Person, in which case the
Subject Issuer Shares will no longer be governed by the Voting Trust  Agreement.
The trust  created  under the  Voting  Trust  Agreement  will  terminate  on the
earliest of December 31, 2001, the date on which the  consummation  of an Issuer
Business  Combination  occurs,  the termination of the Voting Trust Agreement by
the  Reporting  Person or when the  Reporting  Person ceases to hold any Subject
Issuer  Shares.  The  foregoing  description  of the Voting  Trust  Agreement is
qualified in its entirety by reference to the form of Voting Trust Agreement,  a
copy of which is attached  hereto as Exhibit 9.1 and  incorporated  by reference
herein.

         The Purchase  Agreement  also  requires  the  Canadian  Seller (and its
subsidiary)  to  grant  to  the  Reporting  Person  an  irrevocable  proxy  (the
"Irrevocable  Proxy"), to be delivered at the Closing,  appointing the Reporting
Person as proxy, with full power of substitution,  to vote in connection with an
Issuer  Business  Combination  all of the  Subject  Issuer  Shares  owned by the
Canadian Seller (and its subsidiary) as of the applicable record date, as and to
the extent the  Reporting  Person shall  determine in its sole  discretion.  The
Irrevocable  Proxy will cease to apply 

<PAGE>

with respect to any Subject  Issuer Shares  transferred  in accordance  with the
Purchase  Agreement.  The  foregoing  description  of the  Irrevocable  Proxy is
qualified in its entirety by reference to the form of Irrevocable  Proxy, a copy
of which is attached hereto as Exhibit 9.2 and incorporated by reference herein.

         The Purchase  Agreement  also  requires  the  Canadian  Seller (and its
subsidiary) to grant the Reporting Person an irrevocable  option to purchase the
Subject Issuer Shares in accordance with the terms and conditions set forth in a
back-up option agreement (the "Back-Up Option Agreement") to be delivered at the
Closing.  Under the  Back-Up  Option  Agreement,  the  Canadian  Seller (and its
subsidiary)  will  grant to the  Reporting  Person  the  irrevocable  option  to
purchase all of the Subject Issuer Shares at the time the Reporting Person gives
notice of exercise of the option,  provided,  however, that such option may only
be exercised in certain  limited  circumstances.  The option expires on December
31, 2001 and prior to its  expiration  will cease to apply to any Subject Issuer
Shares  that are  disposed  of by the  Canadian  Seller (or its  subsidiary)  in
accordance with the terms of the Purchase Agreement.  In order for the Reporting
Person to exercise the Back-Up  Option,  (i) a vote of the  shareholders  of the
Issuer with respect to an Issuer Business Combination must be scheduled and (ii)
any one of the following  events must occur:  (a) the filing or  commencement by
any party other than the Reporting Person of an action,  suit or proceeding,  to
interpret,  construe, overturn,  invalidate,  block, suspend or otherwise impede
the enforceability of, or the exercise of, the Reporting Person's Limited Voting
Rights or voting rights under the Voting Trust Agreement and Irrevocable  Proxy;
or (b) the revocation or attempted revocation of the Irrevocable Proxy or Voting
Trust  Agreement;  or (c) the breach of,  default of or other  failure to comply
with or the failure to perform any material term or condition by any party other
than the Reporting  Person of the Irrevocable  Proxy, the Voting Trust Agreement
or the applicable  section of the Purchase  Agreement.  The purchase price to be
delivered in  connection  with the exercise of the option would equal the number
of  Subject  Issuer  Shares  specified  for  purchase  in  an  exercise  notice,
multiplied  by 110% of the average  closing  price for one share of the Issuer's
Common Stock for the last ten trading days ending three trading days immediately
prior to the time specified in the option exercise notice given by the Reporting
Person for the closing of the purchase of the Subject  Issuer Shares  covered by
the option. The Reporting Person will be required to make additional payments to
the Canadian Seller if the Reporting Person  subsequently  purchases  additional
shares of the Issuer's Common Stock at a higher price or disposes of the Subject
Issuer Shares acquired upon the exercise of the option within a specified period
after such  acquisition.  It is  anticipated  that,  should  the  option  become
exercisable  and should the Reporting  Person  determine to exercise the option,
the Reporting Person would obtain the funds for purchase from working capital or
by  borrowing  from  parties  whose  identity  is not yet known.  The  foregoing
description  of the Back-Up  Option  Agreement  is  qualified in its entirety by
reference to the form of Back-Up Option  Agreement,  a copy of which is attached
hereto as Exhibit 10.1 and incorporated by reference herein.

         On  November 9, 1998,  the Issuer  issued a press  release  (the "Press
Release") which stated that:  "[I]ts Board of Directors has retained  Donaldson,
Lufkin &  Jenrette  Securities  Corporation  to  advise  it in  connection  with
considering  various  strategic  alternatives to enhance  shareholder  value. No
specific  timetable has been  established by the Board for completing its review
of such  strategic  alternatives."  The Issuer is a significant  customer of the
Reporting Person.  The 

<PAGE>

Reporting  Person  sought the Limited  Voting Rights and the other voting rights
described  herein to provide it with certain  input in the event that the Issuer
became  involved  in an  Issuer  Business  Combination  that  could  affect  the
Reporting Person's ongoing business  relationship with the Issuer.  Furthermore,
in light of the Press  Release,  the Reporting  Person  believed that the voting
rights  described herein could provide the Reporting Person with an advantage in
the event  that the Issuer  were to  conclude,  after  analyzing  its  strategic
alternatives,  that it should  pursue an Issuer  Business  Combination  with the
Reporting Person.

         On January  11,  1999,  the  Reporting  Person,  the Issuer and Peacock
Merger  Corporation,  a newly formed  wholly-owned  subsidiary  of the Reporting
Person  ("Subcorp"),  entered into an Agreement  and Plan of Merger (the "Merger
Agreement").  Under the terms of the Merger  Agreement,  at the closing  Subcorp
will be merged with and into the Issuer,  each outstanding share of the Issuer's
Common Stock will be converted  into 0.275 of a share of the Reporting  Person's
Class A Common Stock,  and the Issuer will become a  wholly-owned  subsidiary of
the  Reporting  Person.  Consummation  of the  closing is  subject  to  numerous
conditions,  including  regulatory approval and the approval of the shareholders
of both the  Reporting  Person  and the  Issuer.  The  proposed  merger  will be
accounted for as a purchase  transaction.  The Reporting  Person intends to vote
the Subject  Issuer  Shares in favor of such  merger at the  special  meeting of
stockholders to be held to vote upon such merger.  The Merger Agreement is filed
as Exhibit 2.2 hereto and is  incorporated  herein by  reference.  The foregoing
description of the Merger Agreement is qualified in its entirety by reference to
such Exhibit.

         Except as set forth  herein,  the  Reporting  Person  does not have any
current plans or proposals that relate to or would result in (i) the acquisition
by  any  person  of  additional  shares  of the  Issuer's  Common  Stock  or the
disposition  of the  Issuer's  Common  Stock,  (ii) an  extraordinary  corporate
transaction,  such as a merger,  reorganization  or  liquidation,  involving the
Issuer or any of its  subsidiaries,  (iii) a sale or  transfer  of any  material
amount of assets of the  Issuer or any of its  subsidiaries,  (iv) any change in
the present board of directors or management of the Issuer,  including any plans
or proposals to change the number or term of directors or to fill any  vacancies
on the board, (v) any material change in the present  capitalization or dividend
policy of the Issuer, (vi) any other material change in the Issuer's business or
corporate   structure,   (vii)  any  change  in  the  Issuer's   Certificate  of
Incorporation or By-Laws, or instruments corresponding thereto, or other actions
that may impede the  acquisition of control of the Issuer by any person,  (viii)
causing a class of  securities  of the  Issuer to be  delisted  from a  national
securities exchange or to cease to be authorized to be quoted in an inter-dealer
quotation system of a registered national securities  association,  (ix) a class
of  equity  securities  of the  Issuer  becoming  eligible  for  termination  of
registration  pursuant to Section  12(g)(4) of the  Securities  Exchange  Act of
1934, as amended, or (x) any action similar to any of those enumerated above.

         Except as set forth herein,  the Reporting  Person has not effected any
transactions in the Issuer's Common Stock during the past sixty days.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to
Securities of the Issuer


<PAGE>

         Except for the  Purchase  Agreement,  the Voting Trust  Agreement,  the
Irrevocable  Proxy, the Back-Up Option Agreement and the Merger Agreement,  none
of  the  persons  named  in  Item  2 has  any  arrangements,  understandings  or
relationships  (legal  or  otherwise)  with  any  person  with  respect  to  any
securities of the Issuer,  including,  but not limited to, transfer or voting of
any securities, finder's fees, joint ventures, loan or option arrangements, puts
or calls,  guarantees  of profits,  division of profits or loss or the giving or
withholding of proxies.

                          AGREEMENT AND PLAN OF MERGER

          This  Agreement  and Plan of  Merger  (this  "Agreement")  is made and
entered into as of the 11th day of January,  1999, by and among Bergen  Brunswig
Corporation,  a New Jersey  corporation  ("Bergen"),  Peacock  Merger  Corp.,  a
Delaware  corporation and a wholly owned subsidiary of Bergen  ("Subcorp"),  and
PharMerica, Inc., a Delaware corporation ("PharMerica").

                             PRELIMINARY STATEMENTS

          A. Bergen desires to combine its pharmaceutical  distribution business
and other  businesses  with the  institutional  pharmacy  and  other  businesses
operated by PharMerica  through the merger of Subcorp with and into  PharMerica,
with PharMerica as the surviving  corporation (the "Merger"),  pursuant to which
each share of PharMerica Common Stock (as defined in Section 3.14.1) outstanding
at the Effective Time (as defined in Section 1.2), together with each associated
right issued under the PharMerica  Rights Agreement (as defined in Section 3.5),
will be  converted  into the right to  receive a  fraction  of a share of Bergen
Common  Stock (as  defined in Section  4.12.1),  together  with a fraction of an
associated  right  under the  Bergen  Shareowners'  Rights  Plan (as  defined in
Section  4.12.1) and cash in lieu of fractional  shares,  as more fully provided
herein.

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

          C.  The  respective  Boards  of  Directors  of  Bergen,   Subcorp  and
PharMerica have determined that the Merger, in the manner  contemplated  herein,
is desirable and in the best interests of their respective  stockholders and, by
resolutions duly adopted, have approved and adopted this Agreement.

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

                                   ARTICLE I.

                                   THE MERGER

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

          1.2.  Effective  Time. As promptly as possible on the Closing Date (as
defined  below),  the parties shall cause the Merger to be consummated by filing
with the Secretary of State of the State of Delaware (the "Delaware Secretary of
State") a certificate of merger (the "Certificate of Merger") in such form as is
required by Section 251 of the DGCL and executed in accordance  with Section 251
of the DGCL. The Merger shall become  effective (the "Effective  Time") when the
Certificate of Merger has been filed with the Delaware  Secretary of State or at
such later time as shall be agreed upon by Bergen and  PharMerica  and specified
in the  Certificate of Merger.  Prior to the filing  referred to in this Section
1.2,  a closing  (the  "Closing")  shall be held at the  offices  of  Lowenstein
Sandler PC, 65 Livingston Avenue, Roseland, New Jersey 07068 or such other place
as the parties may agree,  as soon as practicable  (but in any event within five
business days) following the date upon which all conditions set forth in Article
VI hereof  have been  satisfied  or waived,  or at such other date as Bergen and
PharMerica may agree,  provided that the conditions set forth in Article VI have
been satisfied or waived at or prior to such date. The date on which the Closing
takes place is referred to herein as the "Closing  Date." For all tax  purposes,
the Closing shall be effective at the end of the day on the Closing Date.

          1.3.  Effects of the Merger.  From and after the Effective  Time,  the
Merger shall have the effects set forth in Section 259 of the DGCL.

          1.4.  Certificate of Incorporation  and Bylaws. At the Effective Time,
(i) the Certificate of Incorporation  of the Surviving  Corporation as in effect
immediately  prior to the  Effective  Time shall be amended as of the  Effective
Time so as to  contain  the  provisions,  and  only  the  provisions,  contained
immediately prior thereto in the Certificate of Incorporation of Subcorp, except
for Article I thereof which shall continue to read "The name of the  corporation
is PharMerica, Inc.", and (ii) the Bylaws of Subcorp in effect immediately prior
to the Effective Time shall be the Bylaws of the Surviving Corporation;  in each
case until amended in accordance with applicable law.

          1.5.  Directors  and Officers of the Surviving  Corporation.  From and
after  the  Effective  Time,  individuals  designated  by  Bergen  prior  to the
Effective  Time  shall be the  officers  of the  Surviving  Corporation  and the
directors of Subcorp  shall be the directors of the  Surviving  Corporation,  in
each case until their respective  successors are duly elected and qualified.  On
or prior to the  Closing  Date,  PharMerica  shall  deliver  to Bergen a written
resignation, in form and substance satisfactory to Bergen, from each director of
PharMerica, effective as of the Effective Time.

                                   ARTICLE II.

                            CONVERSION OF SECURITIES

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

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

               2.1.2  Subject to the other  provisions  of this Article II, each
share of PharMerica  Common Stock,  together with each  associated  right issued
under the PharMerica Rights Agreement,  issued and outstanding immediately prior
to the Effective Time shall be converted into the right to receive a fraction of
a share of Bergen  Common  Stock  equal to the  Exchange  Ratio (as  defined  in
Section 2.2.1),  together with the appropriate  fraction of an associated  right
under the Bergen Shareowners' Rights Plan (the consideration referred to in this
Section 2.1.2 being hereinafter referred to as the "Merger Consideration").

               2.1.3  Each  share of  capital  stock of  PharMerica  held in the
treasury of  PharMerica  shall be canceled  and retired and no payment  shall be
made in respect thereof.

         2.2. Exchange Ratio; Fractional Shares; Adjustments.

               2.2.1 The "Exchange Ratio" shall be equal to 0.275.

               2.2.2 No  certificates  for  fractional  shares of Bergen  Common
Stock  shall be issued as a result of the  conversion  provided  for in  Section
2.1.2.  In lieu of any such  fractional  shares,  the  holder  of a  certificate
previously  evidencing  PharMerica  Common  Stock,  upon  presentation  of  such
fractional  interest  represented by an appropriate  certificate  for PharMerica
Common Stock to the Exchange Agent pursuant to Section 2.3, shall be entitled to
receive  a cash  payment  therefor  in an  amount  equal  to the  value  of such
fractional  interest  (determined  by  reference to the average of the per share
last daily  closing  prices of Bergen Common Stock as quoted on the NYSE (and as
reported by The Wall  Street  Journal or, if not  reported  thereby,  by another
authoritative source) during the ten (10) consecutive trading days ending on the
fourth  trading day  immediately  preceding the Closing Date.  Such payment with
respect to fractional shares is merely intended to provide a mechanical rounding
off of, and is not a separately bargained for,  consideration.  If more than one
certificate  representing shares of PharMerica Common Stock shall be surrendered
for the account of the same holder,  the number of shares of Bergen Common Stock
for which  certificates  have been surrendered shall be computed on the basis of
the aggregate number of shares represented by the certificates so surrendered.

               2.2.3 In the event that,  subsequent to the date hereof and prior
to  the  Effective  Time,  Bergen  shall  declare  a  stock  dividend  or  other
distribution payable in shares of Bergen Common Stock or securities  convertible
into shares of Bergen Common Stock,  or effect a stock split,  reclassification,
combination  or other change with respect to shares of Bergen Common Stock,  the
Exchange  Ratio set forth in this  Section 2.2 shall be adjusted to reflect such
dividend,  distribution,  stock split,  reclassification,  combination  or other
change.

         2.3. Exchange of Certificates.

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

               2.3.2  Exchange  Procedures.  As soon as  practicable  after  the
Effective Time,  Bergen shall instruct the Exchange Agent to mail to each holder
of  record  of  a  certificate  or  certificates  (the   "Certificates")   which
immediately  prior to the  Effective  Time  represented  outstanding  shares  of
PharMerica  Common Stock whose shares were  converted  into the right to receive
the Merger Consideration  pursuant to Section 2.1.2 the following:  (i) a letter
of transmittal (which shall specify that delivery shall be effected, and risk of
loss and  title to the  Certificates  shall  pass,  only  upon  delivery  of the
Certificates to the Exchange Agent and shall be in such form and have such other
customary provisions as Bergen may reasonably specify) and (ii) instructions for
effecting  the  surrender  of the  Certificates  in  exchange  for  certificates
representing  shares  of  Bergen  Common  Stock  and cash in lieu of  fractional
shares.  Upon surrender of a Certificate for cancellation to the Exchange Agent,
together  with a duly  executed  letter  of  transmittal,  the  holder  of  such
Certificate  shall be entitled to receive in exchange therefor (x) a certificate
or certificates  representing  the whole number of shares of Bergen Common Stock
which  such  holder  has the right to receive  pursuant  to  Section  2.1.2 (and
representing each associated right under the Bergen Shareowners' Rights Plan) in
such  denominations  and registered in such names as such holder may request and
(y) a check  representing  the amount of cash in lieu of fractional  shares,  if
any, and unpaid dividends and  distributions,  if any, which such holder has the
right to receive  pursuant to the  provisions  of this  Article II, after giving
effect  to  any  required   withholding  tax.  The  shares  represented  by  the
Certificates  so surrendered  shall  forthwith be canceled.  No interest will be
paid or accrued on the cash in lieu of fractional shares, if any, and the unpaid
dividends and distributions,  if any, payable to holders of shares of PharMerica
Common  Stock.  In the event of a transfer of ownership of shares of  PharMerica
Common Stock which is not registered on the transfer  records of  PharMerica,  a
certificate representing the proper number of shares of Bergen Common Stock (and
representing each associated right under the Bergen  Shareowners'  Rights Plan),
together with a check for the cash to be paid in lieu of fractional  shares,  if
any,  and unpaid  dividends  and  distributions,  if any,  may be issued to such
transferee if the  Certificate  representing  such shares of  PharMerica  Common
Stock held by such transferee is presented to the Exchange Agent, accompanied by
all documents required to evidence and effect such transfer and to evidence that
any  applicable  stock  transfer  taxes have been  paid.  Until  surrendered  as
contemplated by this Section 2.3, each  Certificate  shall be deemed at any time
after the Effective Time to represent only the right to receive upon surrender a
certificate  representing  whole shares of Bergen Common Stock issuable pursuant
to Section  2.1.2  (and  representing  each  associated  right  under the Bergen
Shareowners'  Rights Plan) and cash in lieu of  fractional  shares,  if any, and
unpaid dividends and distributions, if any, as provided in this Article II.

               2.3.3   Distributions   with  Respect  to   Unexchanged   Shares.
Notwithstanding  any other  provisions of this Agreement,  no dividends or other
distributions  declared or made after the Effective  Time with respect to shares
of Bergen  Common Stock having a record date after the  Effective  Time shall be
paid to the  holder of any  unsurrendered  Certificate  until the  holder  shall
surrender  such  Certificate  as provided in this  Section  2.3.  Subject to the
effect of all applicable laws, statutes, orders, rules, regulations, policies or
guidelines  promulgated,  or  judgments,  decisions  or orders  entered,  by any
Governmental  Authority  (as  defined  in  Section  2.3.6),  including,  without
limitation,  the Federal  Prescription  Drug  Marketing  Act and  comparable  or
related state law provisions, the Federal Controlled Substances Act of 1970, the
Food, Drug and Cosmetic Act, the Good Manufacturing  Practices  standards of the
Food  and  Drug  Administration  (the  "FDA"),  federal  Medicare  and  Medicaid
statutes,  including,  without  limitation,  42 U.S.C.  Section  1320a-7b and 42
U.S.C.  Section  1395nn  or  related  state or local  statutes  or  regulations,
applicable  state  laws  regulating  pharmacy  or  wholesaling  practices,   the
Occupational  Safety and Health Act and the regulations  promulgated  thereunder
(all such laws, statutes,  orders,  rules,  regulations,  policies,  guidelines,
judgments,  decisions and orders,  collectively,  "Applicable Laws"),  following
surrender  of any such  Certificate,  there  shall be paid to the  holder of the
certificates representing whole shares of Bergen Common Stock issued in exchange
therefor,  without  interest,  (i) at the time of such surrender,  the amount of
dividends or other  distributions  with a record date after the  Effective  Time
theretofore payable with respect to such whole shares of Bergen Common Stock and
not  paid,  less the  amount of any  withholding  taxes  which  may be  required
thereon,  and (ii) at the appropriate payment date subsequent to surrender,  the
amount  of  dividends  or other  distributions  with a  record  date  after  the
Effective Time but prior to surrender and a payment date subsequent to surrender
payable  with  respect to such whole  shares of Bergen  Common  Stock,  less the
amount of any withholding taxes which may be required thereon.

               2.3.4 No Further Ownership Rights in PharMerica Common Stock. All
shares  of  Bergen  Common  Stock  issued  upon  surrender  of  Certificates  in
accordance  with the terms  hereof (and each  associated  right under the Bergen
Shareowners' Rights Plan) and all cash paid pursuant to this Article II shall be
deemed  to  have  been  issued  and  paid  in full  satisfaction  of all  rights
pertaining to such shares of PharMerica  Common Stock represented  thereby,  and
there shall be no further  registration of transfers on the stock transfer books
of PharMerica of shares of PharMerica Common Stock outstanding immediately prior
to the Effective Time. If, after the Effective Time,  Certificates are presented
to the  Surviving  Corporation  for any  reason,  they  shall  be  canceled  and
exchanged as provided in this Section 2.3. Certificates surrendered for exchange
by any person  constituting  an  "affiliate"  of PharMerica for purposes of Rule
145(c)  under  the  Securities  Act of  1933,  as  amended,  and the  rules  and
regulations   promulgated  thereunder  (the  "Securities  Act"),  shall  not  be
exchanged until Bergen has received written undertakings from such person in the
form attached hereto as Exhibit A-1.

               2.3.5  Termination  of Exchange Fund. Any portion of the Exchange
Fund which remains undistributed to PharMerica Stockholders six months after the
date of the mailing required by Section 2.3.2 shall be delivered to Bergen, upon
demand therefor, and holders of Certificates  previously  representing shares of
PharMerica Common Stock who have not theretofore  complied with this Section 2.3
shall  thereafter  look only to  Bergen  for  payment  of any claim to shares of
Bergen Common Stock, cash in lieu of fractional shares thereof,  or dividends or
distributions, if any, in respect thereof.

               2.3.6 No Liability.  None of Bergen, the Surviving Corporation or
the  Exchange  Agent  shall be liable to any  person in respect of any shares of
PharMerica Common Stock (or dividends or distributions  with respect thereto) or
cash from the  Exchange  Fund  delivered  to a public  official  pursuant to any
applicable abandoned property, escheat or similar law. If any Certificates shall
not have been  surrendered  prior to seven years after the Effective Time of the
Merger (or immediately prior to such earlier date on which any cash, any cash in
lieu of  fractional  shares or any  dividends or  distributions  with respect to
whole shares of  PharMerica  Common Stock in respect of such  Certificate  would
otherwise escheat to or become the property of any local,  domestic,  foreign or
multi-national court, arbitration tribunal,  administrative agency,  commission,
legislative   body  or  other   governmental   or   regulatory   body,   agency,
instrumentality  or  authority  (a  "Governmental  Authority")),  any such cash,
dividends or distributions  in respect of such Certificate  shall, to the extent
permitted by Applicable Laws,  become the property of Bergen,  free and clear of
all claims or interest of any person previously entitled thereto.

               2.3.7  Investment  of Exchange  Fund.  The  Exchange  Agent shall
invest any cash included in the Exchange Fund, as directed by Bergen, on a daily
basis. Any interest and other income  resulting from such  investments  shall be
paid to Bergen upon termination of the Exchange Fund pursuant to Section 2.3.5.

         2.4. Treatment of Stock Options and Warrants.

               2.4.1 Conversion of Options.  Prior to the Effective Time, Bergen
and  PharMerica  shall take all such  actions as may be  necessary to cause each
unexpired and unexercised  option (each, a "PharMerica  Option") under all stock
option plans of  PharMerica  in effect on the date hereof which has been granted
by PharMerica to current or former directors,  officers, employees,  consultants
or  representatives  of  PharMerica or to other  persons with  relationships  to
PharMerica  and each  PharMerica  Warrant  (as  defined in  Section  3.14) to be
automatically converted at the Effective Time into an option (a "Bergen Exchange
Option")  or  warrant  (a "Bergen  Exchange  Warrant"),  as the case may be, to
purchase  that  number of shares of Bergen  Common  Stock equal to the number of
shares of PharMerica  Common Stock issuable  immediately  prior to the Effective
Time upon  exercise of the  PharMerica  Option or  PharMerica  Warrant  (without
regard to actual  restrictions  on  exercisability)  multiplied  by the Exchange
Ratio (the  product of such  multiplication  to be rounded to the nearest  whole
number),  with an exercise price equal to the exercise price which existed under
the  corresponding  PharMerica  Option  or  PharMerica  Warrant  divided  by the
Exchange  Ratio (the  quotient  of such  division  to be rounded to the  nearest
penny),  and with other terms and conditions  that are the same as the terms and
conditions of such PharMerica Option or PharMerica  Warrant  immediately  before
the Effective Time;  provided that with respect to any PharMerica Option that is
an "incentive  stock  option"  within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended (the "Code"), the foregoing conversion shall be
carried out in a manner  satisfying  the  requirements  of Section 424(a) of the
Code.  In  connection  with the issuance of Bergen  Exchange  Options and Bergen
Exchange Warrants, Bergen shall (i) reserve for issuance the number of shares of
Bergen  Common  Stock that will become  subject to Bergen  Exchange  Options and
Bergen  Exchange  Warrants  pursuant to this Section 2.4 and (ii) from and after
the Effective Time, upon exercise of Bergen Exchange Options and Bergen Exchange
Warrants,  make available for issuance all shares of Bergen Common Stock covered
thereby, subject to the terms and conditions applicable thereto.

               2.4.2  S-8  Registration  Statement.  Bergen  agrees  to use  its
reasonable  efforts to file with the  Securities  and Exchange  Commission  (the
"SEC") as promptly as practicable  (but in no event more than ten business days)
after the Closing Date a registration statement on Form S-8 or other appropriate
form under the Securities Act to register shares of Bergen Common Stock issuable
upon exercise of the Bergen Exchange  Options and use its reasonable  efforts to
cause such  registration  statement  to remain  effective  until the exercise or
expiration of such options.

             ARTICLE III. REPRESENTATIONS AND WARRANTIES OF PEACOCK

          Except  as  set  forth  in  the  disclosure   statement  delivered  by
PharMerica  to  Bergen  at or  prior to the  execution  of this  Agreement  (the
"PharMerica   Disclosure  Statement")  (each  section  of  which  qualifies  the
correspondingly numbered representation and warranty, regardless of whether such
representation  or warranty  expressly refers to or is qualified by reference to
such PharMerica  Disclosure  Statement),  PharMerica  represents and warrants to
Bergen as follows:

          3.1  Organization  and  Qualification.  Each  of  PharMerica  and  its
Subsidiaries  (as defined in this Section  3.1) is an entity duly  incorporated,
validly  existing and in good standing under the laws of the jurisdiction of its
incorporation  and has the  corporate  power  and  authority  to own,  lease and
operate  its  properties  and  to  conduct  its  business  as  described  in the
PharMerica  SEC Reports (as defined in Section  3.10.1).  Each of PharMerica and
each of PharMerica's  Subsidiaries  is duly qualified to transact  business as a
foreign  corporation  or other  foreign  entity and is in good  standing in each
jurisdiction  in which the conduct of its business or the ownership,  leasing or
operation of its property requires such qualification, except for failures to be
so qualified or in good  standing  which would not,  singly or in the  aggregate
with all  such  other  failures,  have a  PharMerica  Material  Adverse  Effect.
"PharMerica   Material  Adverse  Effect"  means,  with  respect  to  any  event,
occurrence,  matter,  failure of event or occurrence,  change,  effect, state of
affairs, breach, default, violation, fine, penalty or failure to comply (each, a
"Circumstance"),  individually  or taken  together with all other  Circumstances
contemplated  by or in  connection  with any or all of the  representations  and
warranties  made in this Agreement,  a material  adverse effect on the business,
assets (including without limitation intangible assets), liabilities (contingent
or  otherwise),  financial  condition or results of operations of PharMerica and
its Subsidiaries,  taken as a whole; provided, however, that PharMerica Material
Adverse  Effect shall not be deemed to include the impact of: (A) any decline in
the share price of either PharMerica Common Stock or Bergen Common Stock, except
that any effect  underlying  such decline  shall be  considered  in  determining
whether a  PharMerica  Material  Adverse  Effect has occurred to the extent that
such effect would otherwise be so considered); (B) the implementation of changes
in  generally  accepted  accounting  principles;  (C) actions and  omissions  of
PharMerica or its Subsidiaries taken or permitted with the prior written consent
of Bergen after the date hereof; (D) expenses  reasonably incurred by PharMerica
or its  Subsidiaries  in  consummating  the  transactions  contemplated  by this
Agreement;  and (E) the impact of the implementation of the prospective  payment
system for skilled nursing facilities and other long-term care providers, except
to  the  extent  that  such  implementation  would  render  consummation  of the
transactions  contemplated by this Agreement illegal. Neither PharMerica nor any
of its  Subsidiaries is in violation of any of the provisions of its certificate
of incorporation (or other applicable charter document), as amended, or by-laws,
as  amended,  or, if it is a  limited  liability  company  or  partnership,  its
operating agreement,  partnership agreement or other comparable agreement.  True
and  complete  copies  of the  certificate  of  incorporation  and  by-laws,  as
currently in effect,  of PharMerica and copies that are true and complete in all
material respects of the certificate of incorporation and by-laws,  as currently
in effect,  of each Subsidiary of PharMerica  have been previously  delivered or
made available to Bergen. No amendments to the certificate of incorporation,  as
amended,  of PharMerica have been authorized since December 31, 1997 and, except
as set forth in minute books and other  organizational  documents made available
to  Bergen  for its  review,  no  amendments  to the  by-laws,  as  amended,  of
PharMerica  have been  authorized  since December 31, 1997. For purposes of this
Agreement,  all references to the  "Subsidiaries" of PharMerica shall constitute
references  to any entity (i) the accounts of which would be  consolidated  with
those of PharMerica in PharMerica's  consolidated  financial  statements if such
financial  statements  were  prepared  in  accordance  with  generally  accepted
accounting  principles or (ii) of which securities or other ownership  interests
representing more than 50% of the equity or more than 50% of the ordinary voting
power or, in the case of a partnership, more than 50% of the general partnership
interests  or more than 50% of the  profits  or losses  are owned by  PharMerica
and/or one or more subsidiaries of PharMerica.

          3.2  Authority  Relative  to  This  Agreement  .  PharMerica  has  the
corporate  power and authority to execute and deliver this  Agreement  and, upon
obtaining  the approval of a majority of the  outstanding  shares of  PharMerica
Common Stock at the PharMerica  Special Meeting (as defined in Section 3.8.1) or
any adjournment  thereof as authorized  under the DGCL, to consummate the Merger
and the other  transactions  contemplated  hereby. The execution and delivery of
this  Agreement and the  consummation  of the Merger and the other  transactions
contemplated  hereby  have  been  duly and  validly  authorized  by the Board of
Directors of  PharMerica,  and except as stated in the  preceding  sentence,  no
other corporate proceedings on the part of PharMerica are necessary to authorize
this  Agreement  or  to  consummate  the  Merger  and  the  other   transactions
contemplated  hereby.  This  Agreement  has been duly and validly  executed  and
delivered by  PharMerica  and,  assuming the due  authorization,  execution  and
delivery  hereof by Bergen and Subcorp and  subject to  stockholder  approval as
aforesaid, constitutes a valid and binding agreement of PharMerica,  enforceable
against  PharMerica in accordance with its terms,  except to the extent that its
enforceability   may  be   limited   by   applicable   bankruptcy,   insolvency,
reorganization, moratorium or other laws affecting the enforcement of creditors'
rights generally or by general equitable principles.

          3.3 Consents, No Conflicts.

               3.3.1 Except for actions to be taken in  connection  with (a) the
filing of the  Certificate of Merger,  (b) the filing and  effectiveness  of the
Registration  Statement (as hereinafter defined), (c) the filings required under
and in connection  with the  applicable  requirements  of the  Hart-Scott-Rodino
Antitrust  Improvements Act of 1976, as amended (the "HSR Act"), (d) any filings
required under the New Jersey Industrial Site Recovery Act, (e) filings required
pursuant  to any state  securities  or "blue sky" laws,  (f)  filings  and other
matters  relating to the listing on the New York Stock  Exchange (the "NYSE") of
the  shares of Bergen  Common  Stock  required  to be  issued  pursuant  to this
Agreement,  (g) notices to or filings  with the  Internal  Revenue  Service (the
"IRS") or the Pension Benefit Guaranty  Corporation (the "PGBC") with respect to
any employee  benefit  plans (to the extent such notices to and filings with the
IRS or the PGBC are  described  in Section  3.3.1 of the  PharMerica  Disclosure
Statement),  (h) any other filings,  notices,  disclosures or registrations  set
forth in Section  3.3.1 of the  PharMerica  Disclosure  Statement  and (i) other
consents,  filings or  notifications  which,  if not  obtained or made,  are not
reasonably  likely  to have,  individually  or in the  aggregate,  a  PharMerica
Material  Adverse  Effect,  no  filing or  registration  with,  notification  or
disclosure to, or permit, authorization,  consent or approval of, (x) any court,
(y) any government  agency or body or (z) any third party,  whether acting in an
individual,  fiduciary or other  capacity,  is required for the  consummation by
PharMerica of the Merger or the other transactions contemplated hereby.

               3.3.2  Except as set  forth in  Section  3.3.2 of the  PharMerica
Disclosure Statement, the execution,  delivery and performance of this Agreement
and the  consummation  of the  Merger  and the other  transactions  contemplated
hereby and compliance by PharMerica with any of the provisions hereof do not and
will not: (i) subject to  obtaining  the approval of the Merger by a majority of
the outstanding  shares of PharMerica  Common Stock,  conflict with or result in
any breach or violation of any provision of the certificate of incorporation (or
other comparable charter  documents),  as amended,  or by-laws,  as amended,  of
PharMerica  or any of its  Subsidiaries  or,  with  respect to a  Subsidiary  of
PharMerica that is a limited  liability  company or  partnership,  its operating
agreement, partnership agreement or other comparable agreement or (ii) result in
(1) a breach  or  violation  of, a  default  under  or an event  triggering  any
payment,  obligation or acceleration of any obligation  pursuant to any existing
pension  plans,  welfare plans,  multiemployer  plans,  employee  benefit plans,
benefit  arrangements  or similar  plans,  arrangements  or policies,  including
without  limitation bonus,  incentive,  deferred  compensation,  stock purchase,
stock option,  stock appreciation  right,  health or group insurance,  severance
pay, retirement or other benefit plans, and all similar arrangements or policies
of PharMerica and its  Subsidiaries  (the  "PharMerica  Compensation and Benefit
Plans") or any grant or award made under any of the  foregoing,  (2) a breach or
violation of, a default under or an event  triggering a right of termination of,
a default  under,  or the  acceleration  of any  obligation or the creation of a
lien, pledge,  security interest or other encumbrance on assets (with or without
the giving of notice or the lapse of time or both) pursuant to any provision of,
any  agreement,  lease  of  real  or  personal  property,  marketing  agreement,
contract, note, mortgage,  indenture or other obligation of PharMerica or any of
its  Subsidiaries  ("PharMerica  Contracts")  or, subject to making all filings,
notifications  and  disclosures  and  receipt  of all  permits,  authorizations,
consents and  approvals  referred to in clauses "a" through "h" of Section 3.3.1
or in Section  3.3.1 of the  PharMerica  Disclosure  Statement,  any law,  rule,
ordinance or regulation or judgment,  decree, order or award to which PharMerica
or any of its  Subsidiaries is subject or any  governmental or  non-governmental
authorization,  consent, approval,  registration,  franchise,  license or permit
under which PharMerica or any of its Subsidiaries  conducts any of its business,
or (3) any other change in the rights or  obligations  of any party under any of
the  PharMerica  Contracts,  except,  with  respect  to this  clause  (ii),  for
breaches, violations,  defaults, triggering events, creations of liens, pledges,
security  interests  or other  encumbrances  on assets,  or changes in rights or
obligations  which  would not,  singly or in the  aggregate  with all other such
matters, have a PharMerica Material Adverse Effect.

          3.4 Board Recommendation. The Board of Directors of PharMerica has, by
a unanimous  vote of those  Directors in  attendance  at a meeting of such Board
duly held on January 10, 1999  approved and adopted this  Agreement,  the Merger
and the other transactions  contemplated  hereby. At such meeting,  the Board of
Directors of  PharMerica  determined  that the  consideration  to be received by
holders of PharMerica Common Stock pursuant to the Merger is fair to the holders
of shares of PharMerica  Common Stock and  recommended  that the holders of such
shares approve and adopt this Agreement,  the Merger and the other  transactions
contemplated hereby (the "PharMerica Board Recommendation").

          3.5  State  Anti-takeover  Statutes;   Stockholder  Protection  Rights
Agreement.  PharMerica  has  granted  all  approvals  and taken all other  steps
necessary to exempt the Merger and the other  transactions  contemplated  hereby
from the  requirements  and  provisions  of  Section  203 of the  DGCL,  Section
607.0901  of the  Florida  Corporation  Law,  Section  607.0902  of the  Florida
Corporation Law and any other state antitakeover statute or regulation such that
none  of  the  provisions  of any  such  "business  combination,"  "moratorium,"
"control share" or other state antitakeover  statute or regulation (x) prohibits
or restricts either  PharMerica's  ability to perform its obligations under this
Agreement  or its ability to  consummate  the Merger and the other  transactions
contemplated  hereby,  (y) would have the effect of invalidating or voiding this
Agreement or any provision  hereof,  or (z) would subject Bergen to any material
impediment  or  condition in  connection  with the exercise of any of its rights
under this Agreement. A copy of the resolutions adopted by PharMerica's Board to
effect such results,  which  resolutions  have been adopted by a majority of the
"disinterested  directors" (as such term is defined in Section 607.0901(1)(h) of
the Florida  Corporation Law) of PharMerica's Board, has been provided to Bergen
prior to the execution of this  Agreement.  The  Stockholder  Protection  Rights
Agreement,  dated as of August 13,  1998 (the  "PharMerica  Rights  Agreement"),
between  PharMerica and Harris Trust and Savings Bank, as Rights Agent, has been
amended so that,  solely with respect to the  transactions  contemplated by this
Agreement  (after  taking  into  consideration  the  rights  granted  by Counsel
Corporation  and its  affiliates to Bergen as described by Bergen in a report on
Schedule  13D filed by Bergen with the SEC in November  1998),  Bergen is exempt
from the definition of "Acquiring  Person"  contained in the  PharMerica  Rights
Agreement and no "Stock Acquisition  Date",  "Separation Time" or "Flip-in Date"
(as such terms are defined in the PharMerica  Rights  Agreement) will occur as a
result of the  execution  of this  Agreement or the  consummation  of the Merger
pursuant to this Agreement.  The PharMerica Rights Agreement, as so amended, has
not been  further  amended or  modified.  Copies of all such  amendments  to the
PharMerica  Rights  Agreement  have been  previously  provided  to  Bergen.  The
PharMerica  Rights  Agreement  will  expire  pursuant  to  Section  5.2  thereof
immediately prior to the Effective Time.

          3.6 No Existing  Violation,  Default,  Etc.  None of PharMerica or its
Subsidiaries is in violation  (except for any violations which would not, singly
or in the aggregate with all such other violations,  have a PharMerica  Material
Adverse  Effect) of (A) any Applicable Law or (B) any order,  decree or judgment
of any Governmental  Authority having jurisdiction over PharMerica or any of its
Subsidiaries. No event of default or event that, but for the giving of notice or
the lapse of time or both,  would  constitute an event of default,  exists under
any  PharMerica  Contract or any lease,  permit,  license or other  agreement or
instrument to which PharMerica or any of its Subsidiaries is a party or by which
any of them is bound or to which any of the properties,  assets or operations of
PharMerica  or any of its  Subsidiaries  is  subject  (except  for any events of
default or other defaults  which would not,  singly or in the aggregate with all
such other defaults, have a PharMerica Material Adverse Effect).

          3.7 Licenses and Permits.  Each of PharMerica and its Subsidiaries has
such certificates,  permits, licenses, franchises,  consents, approvals, orders,
authorizations and clearances from appropriate  governmental agencies and bodies
("PharMerica Licenses") as are necessary to own, lease or operate its properties
and to conduct  its  business  in the manner  described  in the  PharMerica  SEC
Reports and as presently  conducted and all such  PharMerica  Licenses are valid
and in full force and effect, other than any failure to have any such PharMerica
License or any  failure of any such  PharMerica  License to be valid and in full
force and effect as would not,  singly or in the  aggregate  with all such other
failures,  have a PharMerica Material Adverse Effect.  PharMerica or one or more
of its  Subsidiaries  are  participants  in the  Medicaid  program in the states
listed in Section 3.7 of the PharMerica Disclosure Statement. Each of PharMerica
and its  Subsidiaries  is and,  within the period of all applicable  statutes of
limitations,  has been in compliance with its obligations  under such PharMerica
Licenses and no event has occurred that allows, or after notice or lapse of time
would allow,  revocation or termination of such PharMerica Licenses,  other than
any  such  failure  to be in  compliance  with  such  obligations  or  any  such
revocation or termination as would not, singly or in the aggregate with all such
other failures, revocations or terminations,  have a PharMerica Material Adverse
Effect.  PharMerica  has no knowledge of any facts or  circumstances  that could
reasonably  be expected to result in an  inability of  PharMerica  or any of its
Subsidiaries to renew any PharMerica License, other than any such non-renewal as
would  not,  singly  or in the  aggregate  with  all such  non-renewals,  have a
PharMerica Material Adverse Effect. Subject to making all filings, notifications
and  disclosures  and  receipt  of all  permits,  authorizations,  consents  and
approvals referred to in Section 3.3.1 of the PharMerica  Disclosure  Statement,
neither the  execution  and delivery by  PharMerica  of this  Agreement  nor the
consummation of any of the transactions  contemplated  herein will result in any
revocation  or  termination  of any material  PharMerica  License.  Set forth in
Section 3.7 of the PharMerica  Disclosure  Statement is a true and complete list
of all material  PharMerica  Licenses which are necessary for the conduct of the
business presently conducted by PharMerica and its Subsidiaries.

          3.8 Registration Statement;  Prospectus/Joint Proxy Statement. None of
the  information  supplied  by  PharMerica  for  inclusion  in,  and none of the
information regarding PharMerica and its Subsidiaries  incorporated by reference
in, the  registration  statement under the Securities Act registering the Bergen
Common Stock to be issued pursuant to the Merger (such  registration  statement,
as  amended  by  any  amendments  thereto,  being  referred  to  herein  as  the
"Registration  Statement") or the prospectus/joint proxy statement to be sent to
the  stockholders of Bergen and PharMerica in connection with the annual meeting
of  stockholders of Bergen at which such  stockholders  will be asked to approve
the issuance of Bergen Common Stock  pursuant to the Merger (the "Bergen  Annual
Meeting")  and the special  meeting of the  stockholders  of PharMerica at which
such  stockholders  will be asked to approve the Merger and this  Agreement (the
"PharMerica Special Meeting") (such prospectus/joint proxy statement, as amended
by any amendments  thereto,  being  referred to herein as the  "Prospectus/Joint
Proxy Statement"),  including all amendments and supplements to the Registration
Statement  and  Prospectus/Joint  Proxy  Statement,  shall,  in the  case of the
Registration Statement, at the time the Registration Statement becomes effective
and, in the case of the Prospectus/Joint  Proxy Statement,  on the date or dates
the  Prospectus/Joint  Proxy  Statement is first mailed to Bergen and PharMerica
stockholders  and on the date or  dates of the  Bergen  Annual  Meeting  and the
PharMerica  Special Meeting,  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 the light of the circumstances  under
which they were made, not misleading.

          3.9 Finders or Brokers; Compensation Arrangements. Except as set forth
in Section 3.9 of the PharMerica  Disclosure  Statement,  neither PharMerica nor
any Subsidiary of PharMerica has employed any investment banker,  broker, finder
or  intermediary  in connection with the  transactions  contemplated  hereby who
might be entitled to a fee or any commission the receipt of which is conditioned
in whole or part upon consummation of the Merger. The compensation payable by or
on behalf of PharMerica and its  Subsidiaries  (with respect to the transactions
contemplated  hereby) to any investment banker,  broker,  finder or intermediary
identified in Section 3.9 of the PharMerica Disclosure Statement is set forth in
one or more  engagement  letters  delivered to Bergen prior to the  execution of
this Agreement.

          3.10 SEC Filings.

               3.10.1  Except as set  forth in  Section  3.10 of the  PharMerica
Disclosure Statement, PharMerica (and, with respect to periods prior to December
30, 1997, Captsone Pharmacy Services, Inc.) has, in all material respects, filed
with the SEC all required forms,  reports and documents  required to be filed by
it with the SEC since  December  31, 1994  (collectively,  the  "PharMerica  SEC
Reports"), all of which, when filed (in the case of forms, reports and documents
filed  pursuant to the Exchange Act) or when declared  effective (in the case of
registration  statements filed pursuant to the Securities  Act),  complied as to
form in all material  respects with the applicable  provisions of the Securities
Act and the Exchange Act, as the case may be. As of their respective  dates, the
PharMerica  SEC Reports  (including  documents  included as exhibits  thereto or
incorporated  by reference  therein)  did not contain any untrue  statement of a
material fact or omit to state a material fact required to be stated  therein or
necessary to make the statements  therein,  in light of the circumstances  under
which they were made, not misleading.

               3.10.2  PharMerica  will deliver to Bergen as soon as they become
available  true and  complete  copies  of any  report  or  statement  mailed  by
PharMerica  to its  security  holders  generally or filed by it with the SEC, in
each case  subsequent to the date hereof and prior to the Effective  Time. As of
their respective dates,  such reports and statements  (excluding any information
therein provided by Bergen, as to which PharMerica makes no representation) will
comply as to form in all material respects with the applicable provisions of the
Securities Act and the Exchange Act, will not contain any untrue  statement of a
material fact or omit to state a material fact required to be stated  therein or
necessary to make the statements  therein,  in light of the circumstances  under
which they are made,  not  misleading,  and will further  comply in all material
respects with all applicable  requirements  of law,  except for such failures to
comply as to form,  untrue statements or omissions or further failures to comply
which would not be reasonably likely to have,  individually or in the aggregate,
a  PharMerica  Material  Adverse  Effect.  The  audited  consolidated  financial
statements and unaudited consolidated interim financial statements of PharMerica
and its Subsidiaries to be included or incorporated by reference in such reports
and statements will be prepared in accordance with generally accepted accounting
principles applied on a consistent basis throughout the periods involved (except
as  may  be  indicated  in the  notes  to  such  financial  statements),  and in
accordance  with all  applicable  published  accounting  requirements  under the
Securities  Act and the Exchange  Act,  and will fairly  present in all material
respects the consolidated  financial position of PharMerica and its Subsidiaries
as of  the  dates  thereof  and  the  consolidated  results  of  operations  and
consolidated  cash flows of PharMerica and its Subsidiaries for the periods then
ended (subject,  in the case of any unaudited interim financial  statements,  to
normal  year-end  adjustments  and to the  extent  that  they  may  not  include
footnotes or may be condensed or summary statements);  provided,  however,  that
any pro forma  financial  statements  will not  necessarily be indicative of the
consolidated financial position of PharMerica as of the respective dates thereof
and the consolidated  results of operations and cash flows of PharMerica for the
periods indicated.

          3.11 Financial Statements. The audited year-end consolidated financial
statements and unaudited  consolidated  interim financial statements included or
incorporated  by reference in the  PharMerica  SEC Reports have been 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 to
such financial  statements),  and in accordance  with all  applicable  published
accounting  requirements  under the  Securities  Act and the  Exchange  Act, and
fairly present in all material respects the consolidated  financial  position of
the  entities  described  therein as of the dates  thereof and the  consolidated
results of  operations  and  consolidated  cash flows of such  entities  for the
periods then ended  (subject,  in the case of any  unaudited  interim  financial
statements,  to  normal  year-end  adjustments  and to the  extent  they may not
include footnotes or may be condensed or summary statements); provided, however,
that any pro forma  financial  statements  will not necessarily be indicative of
the  consolidated  financial  position of PharMerica as of the respective  dates
thereof and the consolidated  results of operations and cash flows of PharMerica
for the periods indicated.

          3.12 Absence of Undisclosed Liabilities. Neither PharMerica nor any of
its  Subsidiaries  has any  liabilities or  obligations  of any nature,  whether
absolute,  accrued,  unmatured,  contingent  or  otherwise,  or any  unsatisfied
judgments  or any leases of  personalty  or realty or  unusual or  extraordinary
commitments,  except for those  liabilities or allowances  recorded,  accrued or
reserved against on the PharMerica Balance Sheet (as defined in Section 3.18) or
described in the notes thereto,  and except for liabilities or obligations  that
would  not,  singly  or in the  aggregate,  be  reasonably  expected  to  have a
PharMerica Material Adverse Effect.

          3.13  Absence of Changes or Events.  Except for (a)  matters  publicly
disclosed by PharMerica prior to the date hereof (including  without  limitation
matters disclosed in PharMerica SEC Reports filed prior to the date hereof), (b)
matters disclosed in Section 3.13 of the PharMerica Disclosure Statement and (c)
matters disclosed in Section 3.16 of the PharMerica Disclosure Statement:

               3.13.1  Since   September  30,  1998:   (i)  PharMerica  and  its
Subsidiaries  have conducted  their business in the ordinary course and have not
entered  into  any  material  oral  or  written   agreement  or  other  material
transaction  that is not in the  ordinary  course of  business  (other than this
Agreement)  or that  could  reasonably  be  expected  to result in a  PharMerica
Material  Adverse Effect;  (ii) neither  PharMerica nor any of its  Subsidiaries
have  sustained  any  material  loss or  interference  with  their  business  or
properties  from fire,  flood,  windstorm,  accident,  strike or other  calamity
(whether or not covered by insurance);  (iii) there has been no material  change
in the indebtedness of PharMerica and its Subsidiaries, no change in the capital
stock of PharMerica and no dividend or distribution  of any kind declared,  paid
or made by PharMerica on any class of its capital stock;  (iv) there has been no
event or condition which has caused a PharMerica  Material  Adverse Effect,  nor
any  development,  occurrence  or  state  of  facts  or  circumstances  known to
PharMerica  that could,  singly or in the  aggregate,  reasonably be expected to
result  in a  PharMerica  Material  Adverse  Effect;  and (v)  there has been no
material  change  by  PharMerica  in its  accounting  principles,  practices  or
methods.

               3.13.2  Since  September  30,  1998,  other than in the  ordinary
course  of  business  consistent  with  past  practice,  there  has not been any
increase in the  compensation or other benefits  payable,  or which could become
payable,  by PharMerica,  to its officers or key employees,  or any amendment of
any of the PharMerica Compensation and Benefit Plans.

         3.14  Capitalization.

               3.14.1 The authorized capital stock of PharMerica consists solely
of 300,000,000  shares of PharMerica's  common stock,  par value $0.01 per share
(the "PharMerica  Common Stock"),  and 500,000 shares of PharMerica's  preferred
stock,  par value  $0.01 per share (the  "PharMerica  Preferred  Stock").  As of
December 31, 1998, there were 89,387,106  shares of PharMerica  Common Stock and
no shares of PharMerica  Preferred Stock outstanding and no shares of PharMerica
Common Stock or PharMerica  Preferred Stock were held in PharMerica's  treasury;
and except for shares  which have been  issued upon the  exercise of  PharMerica
Warrants and PharMerica  Options  outstanding  on December 31, 1998,  there have
been no issuances of capital stock of PharMerica  since December 31, 1998. As of
December 31, 1998,  290,000 shares of PharMerica Common Stock were issuable upon
the exercise of outstanding  warrants (the "PharMerica  Warrants") and 5,969,272
shares of PharMerica Common Stock were issuable upon the exercise of outstanding
PharMerica  Options  granted  under the stock  option plans of  PharMerica  (the
"PharMerica  Option Plans");  no shares of PharMerica  Common Stock are reserved
for  issuance  for any  purpose  other than upon  exercise  of such  outstanding
PharMerica Warrants or such outstanding  PharMerica Options or upon the grant of
other  options  pursuant  to the  PharMerica  Option  Plans or  pursuant  to the
PharMerica Rights Agreement.  Since December 31, 1998, no PharMerica Warrants or
PharMerica  Options have been granted and no agreements or commitments have been
made to grant any  PharMerica  Warrants or  PharMerica  Options.  Except for the
foregoing, there are not any existing options,  warrants, calls,  subscriptions,
or other rights or other  agreements  or  commitments  obligating  PharMerica to
issue,  transfer or sell any shares of capital  stock of PharMerica or any other
securities  convertible  into or evidencing  the right to subscribe for any such
shares.  There are no outstanding stock appreciation  rights with respect to the
capital stock of  PharMerica.  All issued and  outstanding  shares of PharMerica
Common  Stock  are  duly   authorized  and  validly   issued,   fully  paid  and
nonassessable  and have  not been  issued  in  violation  of (nor are any of the
authorized  shares of capital stock of, or other equity interests in, PharMerica
subject to) any preemptive or similar rights created by statute, the Certificate
of  Incorporation  or By-laws of PharMerica or any agreement to which PharMerica
is a party or by which it may be bound.

               3.14.2  Except as set forth in Section  3.14.2 of the  PharMerica
Disclosure Statement, there are no (i) obligations,  contingent or otherwise, of
PharMerica or its  Subsidiaries to repurchase,  redeem or otherwise  acquire any
shares of PharMerica Common Stock or provide funds to, or make any investment in
(in the form of a loan,  capital  contribution  or  otherwise),  or provide  any
guarantee  with  respect  to the  obligations  of,  any  other  person,  or (ii)
agreements,   arrangements  or  commitments  of  any  character  (contingent  or
otherwise)  pursuant  to which any person is or may be  entitled  to receive any
payment  based on the  revenues  or  earnings  (or any  component  thereof),  or
calculated in accordance  therewith,  of PharMerica or any of its  Subsidiaries.
Section 3.14.2 of the PharMerica  Disclosure Statement sets forth the contingent
earn-out  obligations to which PharMerica or any of its Subsidiaries is subject.
There are no voting trusts,  proxies or other  agreements or  understandings  to
which  PharMerica is a party or by which PharMerica is bound with respect to the
voting of any shares of capital stock of PharMerica.

               3.14.3  PharMerica  has  delivered  or made  available  to Bergen
complete and correct copies of each of the  PharMerica  Warrants and each of the
plans or agreements  pursuant to which the PharMerica Options have been granted,
including all amendments  thereto.  Section 3.14.3 of the PharMerica  Disclosure
Statement sets forth a complete and correct list of all  outstanding  PharMerica
Warrants and  PharMerica  Options,  setting forth (i) the exercise price of each
outstanding  PharMerica  Warrant  and  PharMerica  Option,  (ii) the  number  of
PharMerica  Warrants  and  PharMerica  Options and (iii) the date of issuance or
grant of each such PharMerica Warrant or PharMerica Option.  Since September 30,
1998, the time periods during which the PharMerica Options may be exercised have
not been extended with respect to any of the PharMerica Options.  Section 3.14.3
of the PharMerica Disclosure Statement sets forth a complete and correct list of
all restricted stock awards applicable to PharMerica Common Stock, including the
recipients and the number of shares of PharMerica Common Stock received or to be
received by each.

          3.15  Capital  Stock of  Subsidiaries.  The only  direct  or  indirect
Subsidiaries  of PharMerica  are those listed in Section 3.15 of the  PharMerica
Disclosure  Statement.  PharMerica  is  directly  or  indirectly  the record and
beneficial  owner of all of the  outstanding  shares of capital stock of each of
its  Subsidiaries,  there are no proxies with respect to such shares,  and there
are not any existing options, warrants, calls, subscriptions, or other rights or
other   agreements  or  commitments   obligating   PharMerica  or  any  of  such
Subsidiaries  to issue,  transfer or sell any shares of capital  stock of any of
such  Subsidiaries or any other  securities  convertible  into or evidencing the
right to subscribe for any such shares. All of such shares so beneficially owned
by PharMerica are duly authorized and validly issued, fully paid,  nonassessable
and free of preemptive  rights with respect thereto and are owned by PharMerica,
directly or indirectly,  free and clear of any claim, lien or encumbrance of any
kind with respect thereto. Except as set forth in Section 3.15 of the PharMerica
Disclosure  Statement,  PharMerica  does  not  directly  or  indirectly  own any
interest in any  corporation,  partnership,  limited  liability  company,  joint
venture or other business association or entity.

          3.16 Litigation. Except as set forth in Section 3.16 of the PharMerica
Disclosure  Statement or in the  PharMerica  SEC Reports,  as of the date hereof
there are no material pending actions,  suits,  proceedings or, to the knowledge
of PharMerica,  investigations by, against or affecting  PharMerica,  any of its
Subsidiaries or any of their properties,  assets or operations,  or with respect
to  which  PharMerica  or any  of  its  Subsidiaries  is  responsible  by way of
indemnity or  otherwise.  Except as set forth in Section 3.16 of the  PharMerica
Disclosure  Statement:  (i) no  pending  or,  to the  knowledge  of  PharMerica,
threatened  actions,  suits,   proceedings  or  investigations  by,  against  or
affecting PharMerica, any of its Subsidiaries or any of their properties, assets
or operations, or with respect to which they are responsible by way of indemnity
or otherwise,  whether or not disclosed in such  PharMerica SEC Reports,  would,
singly or in the aggregate with all such other actions, suits, investigations or
proceedings,  reasonably  be  expected  to have a  PharMerica  Material  Adverse
Effect; and (ii) to the knowledge of PharMerica,  no actions, suits, proceedings
or  investigations  which would  reasonably  be  expected  to have a  PharMerica
Material  Adverse  Effect  are  threatened  or  contemplated  and  there  is  no
reasonable  basis,  to the  knowledge  of  PharMerica,  for  any  action,  suit,
proceeding or  investigation,  whether or not threatened or contemplated,  which
could reasonably be expected to have a PharMerica Material Adverse Effect.

          3.17  Insurance.   PharMerica  and  its  Subsidiaries  have  insurance
policies and fidelity bonds covering it and its Subsidiaries' assets,  business,
equipment,  properties,  operations,  employees,  officers and  directors  which
PharMerica  reasonably  and in good faith  believes  are adequate to conduct the
business of PharMerica and its Subsidiaries.  All premiums due and payable under
all such policies and bonds have been paid,  and PharMerica is otherwise in full
compliance with the terms and conditions of all such policies and bonds,  except
where the failure to have made  payment or to be in full  compliance  would not,
individually or in the aggregate with all such other failures, have a PharMerica
Material  Adverse  Effect.  PharMerica  reasonably  believes  that the  reserves
established by PharMerica and its  Subsidiaries  in respect of all matters as to
which  PharMerica or any of its Subsidiaries  self-insures or carries  retention
and/or  deductibles,  including without limitation workers' medical coverage and
workers' compensation, are adequate and appropriate, and PharMerica is not aware
of any  facts  or  circumstances  existing  as of the  date  hereof  that  would
reasonably  be expected to cause such  reserves to be  materially  inadequate or
inappropriate.  Section 3.17 of the PharMerica Disclosure Statement sets forth a
true and complete list of all insurance  policies,  including  retention  and/or
deductible programs, and fidelity bonds of PharMerica. PharMerica has previously
provided to Bergen's counsel a copy of the existing  insurance policies referred
to in Section 5.13.2.  Section 3.17 of the PharMerica  Disclosure Statement sets
forth  the  amount of the  annual  premium  currently  paid for  directors'  and
officers' liability insurance by PharMerica and its Subsidiaries.

          3.18  Title  to  and  Condition  of  Properties.  PharMerica  and  its
Subsidiaries  have good title to all of the real property and personal  property
reflected on  PharMerica's  September 30, 1998  unaudited  consolidated  balance
sheet  contained in PharMerica's  Quarterly  Report on Form 10-Q for the quarter
ended September 30, 1998 filed with the SEC (the  "PharMerica  Balance  Sheet"),
except for property since sold or otherwise  disposed of in the ordinary  course
of business and  consistent  with past  practice and except for defects of title
which are not  material to  PharMerica  and its  Subsidiaries  taken as a whole.
Neither  PharMerica nor any of its Subsidiaries owns any material real property.
No real or  personal  property  owned  or  leased  by  PharMerica  or any of its
Subsidiaries  is subject to claims,  liens or other  encumbrances of any kind or
character, including, without limitation, mortgages, pledges, liens, conditional
sale agreements, charges, security interests, easements,  restrictive covenants,
rights of way or options,  except for (i) liens for taxes not yet  delinquent or
which  are being  contested  in good  faith by  appropriate  proceedings  and in
respect of which  PharMerica or its appropriate  Subsidiary has set aside on its
books  adequate  reserves  in  accordance  with  generally  accepted  accounting
principles; (ii) mechanics',  carriers',  workers',  repairers',  materialmen's,
landlords'  and other  similar  statutory  or common law liens  incurred  in the
ordinary  course of business for  obligations not yet delinquent or the validity
of which is being  contested  in good faith by  appropriate  proceedings  and in
respect of which  PharMerica or its appropriate  Subsidiary has set aside on its
books  adequate  reserves  in  accordance  with  generally  accepted  accounting
principles;  (iii)  in the  case of real  property,  easements,  rights  of way,
restrictions,  minor defects or irregularities in title that do not individually
or in the aggregate  have a material  adverse  effect on the value or use of the
real  property  encumbered  thereby as  currently  used in the  operation of the
business  of  PharMerica  or  its  Subsidiaries;  (iv)  those  which  would  not
materially  interfere  with the conduct of the  business of  PharMerica  and its
Subsidiaries  (the  encumbrances  described  in clauses (i) through (iv) of this
sentence,  collectively,  the "PharMerica  Permitted  Encumbrances");  (v) those
securing  liabilities  reflected in the PharMerica  Balance Sheet; or (vi) those
described in Section 3.18 of the PharMerica Disclosure Statement.

          3.19 Leases.  There have been  delivered  or made  available to Bergen
true and  complete  copies of each  lease  pursuant  to which  real or  personal
property is held under lease by PharMerica or any of its Subsidiaries  (limited,
in the case of personal property, to leases pursuant to which annual rentals are
reasonably  expected to be at least  $100,000  per year),  and true and complete
copies of each lease  pursuant to which  PharMerica  or any of its  Subsidiaries
leases  real or  personal  property  to others  (limited in the case of personal
property,  to leases pursuant to which annual rentals are reasonably expected to
be at least  $100,000  per  year).  Section  3.19 of the  PharMerica  Disclosure
Statement  sets  forth a true and  complete  list of all such  leases,  and such
leases are the only  leases  that are  material  to the  business  conducted  by
PharMerica and its  Subsidiaries  taken as a whole.  All of the leases so listed
(i) are, in all material  respects,  valid and  subsisting and in full force and
effect with respect to PharMerica and its Subsidiaries, as the case may be, and,
to PharMerica's knowledge, with respect to any other party thereto and (ii) were
entered into as a result of bona fide arm's length  negotiations  with the other
party or parties thereto.  PharMerica or its  Subsidiaries,  as the case may be,
have valid  leasehold  interests in all properties  leased  thereunder  free and
clear of all material liens and  encumbrances  other than  PharMerica  Permitted
Encumbrances. The real properties leased by PharMerica and its Subsidiaries are,
in all material  respects,  in good operating  order and  condition,  subject to
ordinary  wear and  tear.  To  PharMerica's  knowledge,  there  are no  material
structural, mechanical or other defects in any improvements located on such real
properties.

          3.20 Contracts and Commitments. Except as set forth in Section 3.20 of

Subsidiaries  of  medicines,  materials,  supplies  or  equipment  which are not
cancelable  upon 90 days' or less  notice  and  which  either  (i) have not been
entered  into in the  ordinary  course  of  business  and  consistent  with past
practice or (ii) provide for purchase  prices  substantially  greater than those

collection in the ordinary course of business and consistent with past practice,
become absolutely or contingently or otherwise liable for (i) the performance of
any other person, firm or corporation under a contract, or (ii) the whole or any
part  of  the  indebtedness  or  liabilities  of  any  other  person,   firm  or
corporation;

               3.20.3 powers of attorney  outstanding  from PharMerica or any of
its  Subsidiaries  other than as issued in the  ordinary  course of business and
consistent  with past  practice  with  respect to  customs,  insurance,  patent,
trademark or tax matters, or to agents for service of process;

               3.20.4  contracts under which any amount payable by PharMerica or
any of its Subsidiaries is dependent upon, or calculated in accordance with, the
revenues or  earnings  (or any  component  thereof of  PharMerica  or any of its
Subsidiaries;

               3.20.5  contracts  with  any  director,   officer,   employee  or
affiliate of PharMerica or any of its  Subsidiaries  other than in such person's
capacity  as a  director,  officer  or  employee  of  PharMerica  or  any of its
Subsidiaries;

               3.20.6  contracts which limit or restrict where PharMerica or any
of its  Subsidiaries may conduct its business or the type or line of business in
which PharMerica or any of its Subsidiaries may engage;

               3.20.7  contracts  with  any  party  for  the  loan of  money  or

ordinary course of business and consistent with past practice); or

               3.20.8 any material hedging, option,  derivative or other similar
transaction.

True and complete copies of all contracts, obligations and commitments listed in
Section 3.20 of the PharMerica  Disclosure Statement have been delivered or made
available to Bergen. None of PharMerica or its Subsidiaries or, to the knowledge
of  PharMerica,  any other  party is in breach  of or  default  under any of the
contracts,  obligations and commitments listed in Section 3.20 of the PharMerica
Disclosure  Statement  or under  any other  PharMerica  Contracts  (and,  to the
knowledge of PharMerica,  no facts or circumstances exist which could reasonably
support the  assertion  of any such breach or default)  except for  breaches and
defaults  which  would  not,  singly or in the  aggregate  with all  other  such
breaches, have a PharMerica Material Adverse Effect.

          3.2l Labor Matters.  None of PharMerica or its Subsidiaries is a party
to any  union  contract  or  other  collective  bargaining  agreement.  Each  of
PharMerica and its  Subsidiaries is in compliance in all material  respects with
all applicable laws respecting  employment and employment  practices,  terms and
conditions of employment,  safety,  wages and hours, and neither  PharMerica nor
any of its Subsidiaries is engaged in any unfair labor practice, except for such
failures to comply or unfair labor  practices as could not,  individually  or in
the aggregate, reasonably be expected to result in a PharMerica Material Adverse
Effect.  There is no labor  strike,  slowdown  or stoppage  pending  (or, to the
knowledge of  PharMerica,  any labor strike or stoppage  threatened)  against or
affecting PharMerica or any of its Subsidiaries.  To PharMerica's  knowledge, no
union  organizing  activities  with  respect to any of its or its  Subsidiaries'
employees are occurring or threatened.

          3.22 No Change of Control Puts. Except as described in Section 3.22 of
the  PharMerica  Disclosure  Statement,  neither the  execution  and delivery by
PharMerica  of this  Agreement nor the  consummation  of the Merger or any other
transaction  contemplated  hereby gives rise to any  obligation of PharMerica or
any of its  Subsidiaries  to, or any  right of any  holder  of any  security  of
PharMerica or any of its Subsidiaries to require PharMerica to, purchase,  offer
to purchase,  redeem or otherwise prepay or repay any such security,  or deposit
any funds to effect the same.

          3.23  Employment and Labor  Contracts.  Except as set forth in Section
3.23 of the PharMerica Disclosure  Statement,  neither PharMerica nor any of its
Subsidiaries is a party to any employment,  management services, consultation or
other  contract  or  agreement  with any past or present  officer,  director  or
employee or, to the knowledge of PharMerica, any entity affiliated with any past
or present officer,  director or employee, other than the agreements executed by
employees generally, the forms of which have been provided to Bergen.

          3.24 Intellectual Property Rights.  PharMerica or its Subsidiaries own
or have the right to use all material  Intellectual  Property Rights (as defined
in this Section 3.24) necessary to the conduct of their  respective  businesses.
Subject to obtaining  any  associated  consents  with respect to  agreements  or
licenses listed in Section 3.3.2 of the PharMerica  Disclosure  Statement,  each
Intellectual  Property  Right  owned  or  used  by  PharMerica  or  any  of  its

merger,  dated as of April 15, 1997, by and among  Capstone  Pharmacy  Services,
Inc.  and  Beverly  Enterprises,  Inc.  and the related  distribution  agreement

agreement,  the "April 1997  Agreements")  were  binding  (within the meaning of
Section  1012(d)(3)(A) of the Taxpayer Relief Act of 1997) on April 15, 1997 and
at all times thereafter.  All of the information  submitted and  representations
made to the  Internal  Revenue  Service in  connection  with the private  letter
ruling request(s)  regarding the transactions  described in such agreements were
accurate  and  complete  in all  material  respects  at  the  time  such  ruling
request(s) were made. To the knowledge of PharMerica,  there is no evidence that
would  preclude  PharMerica  or Bergen  from  establishing,  pursuant to Section
355(e)(2)(B)  of the  Code,  that  (i) the  Merger  and  (ii)  the  transactions
consummated by Capstone Pharmacy Services,  Inc. and Beverly  Enterprises,  Inc.
pursuant to the April 1997  Agreements  are "not pursuant to a plan or series of
related transactions" (within the meaning of such Code Section).

          3.26 Employee Benefit Plans; ERISA.

               3.26.1  Except as set  forth in  Section  3.26 of the  PharMerica
Disclosure  Statement,  there are no "employee pension benefit plans" as defined
in Section  3(2) of the Employee  Retirement  Income  Security  Act of 1974,  as
amended  ("ERISA"),  maintained  or  contributed  to by PharMerica or any of its
Subsidiaries or any of their ERISA  Affiliates (as hereinafter  defined),  or to
which  PharMerica or any of its  Subsidiaries  or any of their ERISA  Affiliates
contributes  or is obligated to make  payments  thereunder or otherwise may have
any  liability  ("PharMerica  Pension  Benefit  Plans").  For  purposes  of this
Agreement,  "ERISA  Affiliate" shall mean any person (as defined in Section 3(9)
of ERISA) that is a member of any group of persons  described in Section 414(b),
(c),  (m)  or  (o)  of  the  Code  which  includes  PharMerica  or  any  of  its
Subsidiaries.

               3.26.2  PharMerica has delivered or made available to Bergen true
and complete copies of, and Section 3.26 of the PharMerica  Disclosure Statement
lists, all PharMerica Pension Benefit Plans, "welfare benefit plans" (as defined
in Section 3(1) of ERISA) covering employees (or former  employees),  maintained
or  contributed  to by  PharMerica  or any of its  Subsidiaries  or under  which
PharMerica  or  any  of  its  Subsidiaries  otherwise  may  have  any  liability
("PharMerica  Welfare Plans"),  all  multiemployer  plans (as defined in Section
3(37) of ERISA) to which  PharMerica or any of its  Subsidiaries or any of their
ERISA  Affiliates  is required to make  contributions  or otherwise may have any
liability  (which  multiemployer  plans are  designated  as such in such Section
3.26), and all stock bonus,  stock option,  restricted stock, stock appreciation
right,  stock purchase,  bonus,  incentive,  deferred  compensation,  severance,
change  of  control,  executive  compensation,  "top  hat,"  other  equity-based
compensation,  and vacation plans,  agreements,  or  arrangements  maintained or
contributed to by PharMerica or any of its Subsidiaries.

               3.26.3 PharMerica and each of its  Subsidiaries,  and each of the
PharMerica Pension Benefit Plans,  PharMerica Welfare Plans, and all other plans
or  arrangement  referenced in Section  3.26.2  (collectively,  the  "PharMerica
Employee Benefit Plans") are, and have been  maintained,  in compliance with the
applicable  provisions  of ERISA  and other  Applicable  Laws  except  where the
failure to comply would not, singly or in the aggregate,  reasonably be expected
to have a PharMerica Material Adverse Effect.

               3.26.4 All material  contributions  to and all material  payments
from the PharMerica  Employee Benefit Plans which are required to have been made
in accordance with the PharMerica  Employee  Benefit Plans and, when applicable,
Section 302 of ERISA or Section 412 of the Code, have been timely made.

               3.26.5 The PharMerica  Pension  Benefit Plans intended to qualify
under  Section  401(a)  of  the  Code  either  (i)  have  a  current   favorable
determination letter from the IRS, or (ii) have been submitted on a timely basis
to obtain a  favorable  determination  letter,  and nothing  has  occurred  with
respect to such  PharMerica  Pension  Benefit Plans which is likely to cause the
loss of tax  qualified  status or  exemption or the  imposition  of any material
liability, penalty, or tax under ERISA or the Code. Such plans have been amended
to the extent required to maintain the qualified status of the plans.

               3.26.6 There are (i) no  investigations  or audits pending or, to
the knowledge of PharMerica, threatened by any governmental entity involving any
PharMerica Employee Benefit Plan, (ii) no termination  proceedings involving any
PharMerica  Pension  Benefit  Plan and (iii) no pending or, to the  knowledge of
PharMerica,  threatened  claims  (other  than  routine  uncontested  claims  for
benefits),  suits or  proceedings  relating to any PharMerica  Employee  Benefit
Plan,  against  the assets of any of the trusts  under any  PharMerica  Employee
Benefit Plan or against any fiduciary of any  PharMerica  Employee  Benefit Plan
who is  PharMerica,  any  Subsidiary of  PharMerica,  any officer or employee of
PharMerica  or  its  Subsidiaries  or,  to  PharMerica's  knowledge,  any  other
fiduciary,  except for those which would not,  singly or in the aggregate,  give
rise to any  liability  which would  reasonably be expected to have a PharMerica
Material  Adverse  Effect,  nor, to the knowledge of  PharMerica,  are there any
facts which could give rise to any such  liability  except for those which would
not,  singly or in the  aggregate,  reasonably  be expected to have a PharMerica
Material Adverse Effect in the event of any such  investigation,  claim, suit or
proceeding.

               3.26.7 No  trustee,  administrator,  fiduciary  or any  "party in
interest"  or  "disqualified  person" with  respect to any  PharMerica  Employee
Benefit Plan who is PharMerica,  any  Subsidiary of  PharMerica,  any officer or
employee of PharMerica or its  Subsidiaries or, to PharMerica's  knowledge,  any
other trustee,  administrator,  fiduciary,  "party-in-interest"  or disqualified
person,  has engaged in a "prohibited  transaction"  (as such term is defined in
Section 4975 of the Code or Section 406 of ERISA) which could result in a tax or
penalty on PharMerica or any of its Subsidiaries  under Section 4975 of the Code
or Section 502(i) of ERISA,  except any such event which would not, singly or in
the  aggregate,  reasonably  be expected to have a PharMerica  Material  Adverse
Effect.

               3.26.8 None of the PharMerica Pension Benefit Plans is subject to
Title IV of ERISA.

               3.26.9  Neither  PharMerica  nor any Subsidiary of PharMerica nor
any ERISA  Affiliate  has incurred any  currently  outstanding  liability to the
Pension  Benefit  Guaranty  Corporation  (the "PBGC") or to a trustee  appointed
under  Section  4042(b) or (c) of ERISA (other than for the payment of premiums,
all of which have been paid when due) and  PharMerica  has no  knowledge  of any
events,  facts or conditions  which reasonably could be expected to give rise to
any  such  liability.  No  PharMerica  Pension  Benefit  Plan has  applied  for,
received,  or been the  subject of, a waiver of the  minimum  funding  standards
imposed by Section 412 of the Code.

               3.26.10 Neither  PharMerica,  any of its  Subsidiaries nor any of
their ERISA  Affiliates  has any liability  (including  without  limitation  any
contingent   liability  under  Section  4204  of  ERISA)  with  respect  to  any
multiemployer plan, within the meaning of Section 3(37) of ERISA.

               3.26.11 With respect to each of the PharMerica  Employee  Benefit
Plans,  true,  correct and complete copies of the following  documents have been
delivered or made  available to Bergen:  (i) the current plans and related trust
documents,   including  amendments  thereto,   (ii)  any  current  summary  plan
descriptions,  (iii) the three most recent Forms 5500,  financial statements and
actuarial  reports,  if applicable,  and (iv) the most recent IRS  determination
letter, if applicable.

               3.26.12 Neither PharMerica, nor to PharMerica's knowledge, any of
its Subsidiaries,  any organization to which PharMerica is a successor or parent
corporation,  within the meaning of Section  4069(b) of ERISA,  nor any of their
ERISA Affiliates has engaged in any  transaction,  within the meaning of Section
4069(a) of ERISA,  except where the liability  therefor would not,  singly or in
the  aggregate,  reasonably  be expected to have a PharMerica  Material  Adverse
Effect.

               3.26.13  None  of the  PharMerica  Welfare  Plans  maintained  by
PharMerica or any of its  Subsidiaries  include  retiree life or retiree  health
benefits or provide for continuing  benefits or coverage for any  participant or
any beneficiary of a participant following termination of employment,  except as
may be required  under the  Consolidated  Omnibus Budget  Reconciliation  Act of
1985,  as  amended  ("COBRA").  PharMerica  and each of its  Subsidiaries  which
maintain a "group  health plan" within the meaning of Section  5000(b)(1) of the
Code have  complied  with the notice and  continuation  requirements  of Section
4980B of the  Code,  COBRA,  Part 6 of  Subtitle  B of Title I of ERISA  and the
regulations thereunder,  except where the failure to comply would not, singly or
in the aggregate,  reasonably be expected to have a PharMerica  Material Adverse
Effect.

               3.26.14  No  material  liability  under any  PharMerica  Employee
Benefit  Plan has been funded or satisfied by or with the purchase of a contract
from an insurance  company as to which PharMerica or any of its Subsidiaries has
received notice that such insurance company is in rehabilitation.

               3.26.15  Except as set forth in  Section  3.26 of the  PharMerica
Disclosure Statement, the consummation of the transactions  contemplated by this
Agreement  will not  result in an  increase  in the  amount of  compensation  or
benefits,   deemed   satisfaction   of  goals  or  conditions,   forgiveness  or
modification  of loans,  or  accelerate  the vesting or timing of payment of any
benefits  or  compensation  payable to or in respect of any  employee  or former
employee of PharMerica or any of its Subsidiaries.

               3.26.16 Intentionally omitted.

               3.26.17 With respect to each PharMerica Employee Benefit Plan and
any other similar arrangement or plan either currently or previously terminated,
maintained,  or  contributed  to by any entity  which either is currently or was
previously  under common control with  PharMerica or any of its  Subsidiaries as
determined under Section 414 of the Code, no event has occurred and no condition
exists that after the Merger could  subject  PharMerica  or Bergen,  directly or
indirectly,  to any material liability  (including without limitation  liability
under any indemnification  agreement) under Section 412, 4971, 4975, or 4980B of
the Code or Section 502, 601 or 606 of ERISA.

               3.26.18 All material  contributions  and all material payments to
or with respect to each PharMerica  Employee  Benefit Plan have been timely made
and PharMerica has made adequate provision for reserves to satisfy contributions
and  payments  that  have not been made  because  they are not yet due under the
terms of such plan or related  arrangement,  document,  or  applicable  law.  No
PharMerica Employee Benefit Plan has any material unfunded benefits that are not
fully reflected in the PharMerica Balance Sheet.

               3.26.19  No  agreement,   commitment,  or  obligation  exists  to
increase,  in any material respect,  any benefits under any PharMerica  Employee
Benefit Plan or to adopt any new PharMerica Employee Benefit Plan.

         3.27     Environmental Matters.

               3.27.1 Except as would not,  singly or in the aggregate  with all
other such  instances  of  non-compliance,  have a PharMerica  Material  Adverse
Effect,  PharMerica  and its  Subsidiaries  are,  and  within  the period of all
applicable  statutes of limitation  have been, in compliance with all applicable
Environmental Laws (as hereinafter defined), which compliance includes,  without
limitation,  the possession of all licenses,  permits,  registrations  and other
governmental  authorizations  (collectively,   "Environmental   Authorizations")
required under all applicable  Environmental Laws, and compliance with the terms
and conditions  thereof,  and there are no  circumstances of which PharMerica is
aware which may  materially  prevent or interfere  with such  compliance  in the
future. To PharMerica's knowledge,  all Environmental  Authorizations  currently
held by  PharMerica  and its  Subsidiaries  pursuant to  Environmental  Laws are
identified  in  Section  3.27.1  of  the  PharMerica  Disclosure  Statement  and
represent  all  Environmental  Authorizations  necessary  for the conduct of the
businesses of PharMerica and its  Subsidiaries as currently  conducted.  Neither
PharMerica nor any of its Subsidiaries has been notified,  or has any reasonable
basis to believe,  that any such Environmental  Authorizations will be modified,
suspended  or  revoked  or cannot be  renewed  or  otherwise  maintained  in the
ordinary  course of business.  To  PharMerica's  knowledge,  the  execution  and
delivery  of  this  Agreement  and  the   consummation   by  PharMerica  of  the
transactions  contemplated  hereby  will not affect the  validity or require the
transfer  of  any  Environmental  Authorizations,   and  will  not  require  any
notification,  registration,  reporting,  filing,  investigation  or remediation
under any applicable Environmental Laws.

               3.27.2  There  are  no  Environmental   Notices  (as  hereinafter
defined) that,  singularly or in the aggregate,  reasonably could be expected to
have a PharMerica  Material  Adverse  Effect (i) pending or, to the knowledge of
PharMerica,  threatened against  PharMerica or any of its Subsidiaries,  (ii) to
the knowledge of PharMerica,  pending or threatened against any person or entity
whose liability for such Environmental Notice could reasonably be expected to be
imputed  or  attributed  by  law  or  contract  to  PharMerica  or  any  of  its
Subsidiaries, (iii) that to the knowledge of PharMerica could subject PharMerica
to any  material  risk of  liability,  loss  or  damages,  or  (iv)  that to the
knowledge of  PharMerica  could  reasonably  be expected to require any material
investigation,  removal or remedial or corrective action by PharMerica or any of
its  Subsidiaries.  Since  December 31, 1997 neither  PharMerica  nor any of its
Subsidiaries has received any  Environmental  Notice alleging that PharMerica or
any of its Subsidiaries is subject to liability under any  Environmental  Law or
that  PharMerica or any of its  Subsidiaries  is not in full compliance with all
applicable Environmental Laws.

               3.27.3  There is no civil,  criminal  or  administrative  action,
suit, demand,  claim, hearing,  notice of violation,  notice or demand letter or
request  for  information  or, to the  knowledge  of  PharMerica,  investigation
pending or, to the knowledge of PharMerica,  threatened under any  Environmental
Law (i) against PharMerica or any of its Subsidiaries,  or (ii) to the knowledge
of PharMerica  against any person or entity in connection  with which  liability
could  reasonably  be expected to be imputed or attributed by law or contract to
PharMerica or any of its Subsidiaries,  except,  with respect to each of clauses
(i) and (ii), for such demands,  claims, notices of violation,  notice or demand
letters or requests for  information  which singly or in the aggregate could not
reasonably be expected to have a PharMerica Material Adverse Effect.

               3.27.4 To the  knowledge of  PharMerica,  no property or facility
presently  or formerly  owned,  operated or leased by  PharMerica  or any of its
present  Subsidiaries,  or to the  knowledge  of  PharMerica  any of its  former
Subsidiaries,  or any of their respective predecessors in interest, is listed or
proposed  for  listing  on the  National  Priorities  List or the  Comprehensive
Environmental Response,  Compensation and Liability Information System, pursuant
to the Comprehensive Environmental Response,  Compensation and Liability Act, as
amended   ("CERCLA"),   or  on  any  comparable  list   established   under  any
Environmental  Law, nor has PharMerica or any of its  Subsidiaries  received any
written  notification  of  potential  or actual  liability  or any  request  for
information under CERCLA or any comparable foreign, state or local law.

               3.27.5  Other  than  in  material   compliance   with  applicable
Environmental Laws, there has been no disposal,  spill,  discharge or release of
any Hazardous Materials (as hereinafter defined) generated,  used, owned, stored
or controlled by  PharMerica,  or, to the  knowledge of  PharMerica,  any of its
Subsidiaries or any of their respective predecessors in interest on, at or under
any property presently or formerly owned, leased or operated by PharMerica,  or,
to the  knowledge  of  PharMerica,  its  Subsidiaries,  or any  predecessors  in
interest,  and to the knowledge of PharMerica  there are no Hazardous  Materials
located  in,  at, on or under,  or in the  vicinity  of,  any such  facility  or
property,  or at any other  location,  that (i) could  reasonably be expected to
subject PharMerica to a material risk of liability,  loss or damages,  or result
in PharMerica's incurring material costs under any Environmental Law, (ii) could
reasonably  be expected to form the basis of any material  Environmental  Notice
against or with respect to PharMerica or any of its Subsidiaries, or against any
person or entity whose liability for any  Environmental  Notice could reasonably
be expected to be imputed or  attributed by law or contract to PharMerica or any
of its  Subsidiaries or (iii) could  reasonably be expected to require  material
investigation,  removal or remedial or corrective action by PharMerica or any of
its  Subsidiaries,  that in any case  singularly or in the aggregate  reasonably
could be expected to have a PharMerica Material Adverse Effect.

               3.27.6  Other  than  in  material   compliance   with  applicable
Environmental Laws, without in any way limiting the generality of the foregoing,
to the knowledge of  PharMerica  (i) there are and have been no  underground  or
aboveground  storage tanks or other  storage  receptacles  or related  piping or
other  disposal areas  containing  Hazardous  Materials  located on, at or under
property owned, operated or leased by PharMerica, any of its Subsidiaries or any
of their  respective  predecessors in interest,  (ii) there are and have been no
polychlorinated biphenyls located on any properties owned, operated or leased by
PharMerica or any of its Subsidiaries,  and (iii) there is no asbestos contained
in or forming  part of any  building,  building  component,  structure or office
space owned, operated or leased by PharMerica or any of its Subsidiaries.

               3.27.7 To the knowledge of PharMerica,  no lien has been recorded
under any Environmental Law with respect to any properties, assets or facilities
owned, operated or leased by PharMerica or any of its Subsidiaries.

               3.27.8   PharMerica   has  given   Bergen   and  its   authorized
representatives  access to all  records and files in its  possession  or control
relating to actual or potential  compliance or liability issues of PharMerica or
its Subsidiaries and any of their respective  predecessors in interest under any
Environmental  Laws,  including,   without  limitation,  all  reports,  studies,
analyses,  tests or monitoring  results pertaining to the existence of Hazardous
Material or any other  environmental  concern relating to properties,  assets or
facilities  currently or formerly  owned,  operated,  managed,  leased,  used or
controlled  by PharMerica or any of its  Subsidiaries,  or otherwise  concerning
compliance with or liability under any Environmental Laws.

               3.27.9  For purposes of this Agreement:

               3.27.9.1 "Environment" shall mean any surface water,  groundwater
or drinking water supply,  land surface or subsurface  strata or ambient air and
includes, without limitation, any indoor location.

               3.27.9.2  "Environmental Laws" shall mean CERCLA, the Solid Waste
Disposal  Act, the Resource  Conservation  and Recovery Act of 1976, as amended,

regulating, relating to or imposing liability or standards of conduct concerning
air emissions,  water  discharges,  noise  emissions,  the release or threatened
release  or  discharge  of any  Hazardous  Material  into the  Environment,  the
generation, handling, treatment, storage, transport or disposal of any Hazardous
Material or otherwise  concerning  pollution or the protection of the outdoor or
indoor Environment,  or employee health or safety. The term "Environmental Laws"
shall also include laws  governing  the transfer of real  property or a business
that require notification,  registration,  reporting,  filing,  investigation or
remediation  prior to,  concurrent with or following sale or transfer of control
of any property,  facility or  establishment  in  connection  with the actual or
threatened presence or release of Hazardous Materials at such property, facility
or establishment.

               3.27.9.3  "Environmental   Notice"   shall   mean   any   written
communication,  notice or claim by any  Governmental  Authority  or other  third
party  alleging  civil or criminal  liability  (including,  without  limitation,
liability for investigatory costs, cleanup costs, governmental costs, compliance
costs or harm, injuries or damages to any person,  property,  natural resources,
or any fines or penalties) or alleging noncompliance arising out of, based upon,
resulting from or relating to any Environmental Law.

               3.27.9.4   "Hazardous   Material"   shall  mean  any   pollutant,

Environmental Law.

         3.28     Intentionally omitted.

         3.29     Institutional Pharmacy Business.

               3.29.1 Section 3.29 of the PharMerica  Disclosure Statement lists
each pharmacy  utilized by PharMerica and its  Subsidiaries  in connection  with
their pharmacy business and indicates (i) the location of each such pharmacy and
(ii) whether such  pharmacy  premises are owned or held  pursuant to a leasehold
interest,  management agreement or otherwise.  No other person or entity has any
beneficial  ownership or interest in or to any such  pharmacy nor does any other
person or entity have any right or option to acquire any beneficial ownership or
interest in or to any such pharmacy.

               3.29.2 Section 3.29 of the PharMerica  Disclosure Statement lists
all of the customers to which PharMerica and its Subsidiaries  provided pharmacy
services  pursuant  to oral or written  contracts  which  generated  revenues in
excess of $10,000,000 for the year ended December 31, 1997 ("PharMerica Pharmacy
Contracts").  Except as set forth in such Section 3.29,  PharMerica has not been
informed,  and has no reason to believe,  that any PharMerica  Pharmacy Contract
will be terminated for or without cause.

               3.29.3 To PharMerica's  knowledge,  none of PharMerica nor any of
its  Subsidiaries  has  violated or is in  violation  of any law or order of any
court  or  governmental  authority  that is  applicable  to any of  them,  their
businesses  or their  properties,  including but not limited to the Medicare and
Medicaid  fraud and abuse  provisions  of the  Social  Security  Act,  the Civil
Monetary Penalties Law of the Social Security Act, the so called "Stark" law, 42
USC  Section  1395nn,  or any  other  federal  or state  law,  statute,  rule or
regulation  prohibiting  rebates,  kickbacks,  fee-splitting  or other financial
incentives or  inducements,  including but not limited to providing  products or
services below cost for the referral or continuation of business, except for any
past  or  present  violations  which  could  not,  singly  or in the  aggregate,
reasonably be expected to result in a PharMerica  Material Adverse Effect.  None
of PharMerica or its  Subsidiaries  is, to the  knowledge of  PharMerica,  under
investigation by the Office of Inspector General of the Department of Health and
Human Services or any other federal or state investigatory or regulatory body or
agency  relating to their business  activities,  nor is PharMerica  aware of any
state of facts which could  reasonably  be likely to subject  PharMerica  or its
Subsidiaries to a claim for civil penalties (other than penalties which would be
immaterial to PharMerica and its Subsidiaries, taken as a whole), criminal fines
or other sanctions  (other than criminal fines or other sanctions which would be
immaterial to PharMerica and its Subsidiaries, taken as a whole) with respect to
a violation or claimed violation of any such laws or regulations relating to the
conduct of their business.

               3.29.4  Intentionally omitted.

               3.29.5 To PharMerica's knowledge, PharMerica and its Subsidiaries
have  delivered  or  made  available  true  and  correct  billing  requests  for
reimbursement and underlying information to all governmental programs, including
but not limited to the Medicare and Medicaid programs, in substantial compliance
with all  rules,  regulations,  policies  and  procedures  of such  governmental
programs  and of the  fiscal  intermediaries  of such  programs,  except for any
failures to be true and correct or any failures to be in compliance  which could
not,  singly  or in  the  aggregate,  reasonably  be  expected  to  result  in a
PharMerica  Material  Adverse Effect.  To the knowledge of PharMerica,  all such
billings were for goods and/or  services  actually  provided,  and at charges or
costs  that  were  lawful  in all  material  respects,  and  PharMerica  and its
Subsidiaries  have appropriate  documentation to support such billing  requests,
except  for  any  charges  or  costs  (if  deemed  to be  unlawful)  or  lack of
documentation that could not, singly or in the aggregate, reasonably be expected
to  result  in a  PharMerica  Material  Adverse  Effect.  To  the  knowledge  of
PharMerica, all accounts receivable of PharMerica and its Subsidiaries reflected
in the  PharMerica  Balance Sheet  represent,  in all material  respects,  valid
claims against  debtors for sales of products or services or other charges on or
before the date of the PharMerica  Balance Sheet, are not subject to discount to
any material extent except for normal cash discounts and have been appropriately
reduced, in all material respects, to their estimated net realizable value.

          3.30  Fairness  Opinion.   PharMerica  has  received  the  opinion  of
Donaldson Lufkin & Jenrette Securities  Corporation to the effect that as of the
date hereof the Merger Consideration is fair to PharMerica's stockholders from a
financial point of view.

          3.31 Year 2000.  Subject to the  completion  schedule set forth in the
most recent  PharMerica SEC Report  heretofore filed by PharMerica with the SEC,
PharMerica and its Subsidiaries have taken, in all material respects,  the steps
described in the PharMerica SEC Reports with respect to the computer systems and
software of PharMerica and its  Subsidiaries  relating to the  specification  of
dates in, into and between the 20th and 21st centuries.

                                   ARTICLE IV.

                  REPRESENTATIONS AND WARRANTIES OF BLUEJAY AND
                                     SUBCORP

          Except as set forth in the disclosure statement delivered by Bergen to
PharMerica  at or  prior  to  the  execution  of  this  Agreement  (the  "Bergen
Disclosure  Statement")  (each section of which  qualifies  the  correspondingly
numbered representation and warranty,  regardless of whether such representation
or warranty  expressly  refers to or is  qualified  by  reference to such Bergen
Disclosure  Statement),  Bergen and Subcorp jointly and severally  represent and
warrant to PharMerica as follows:

          4.1   Organization   and   Qualification.   Each  of  Bergen  and  its
Subsidiaries  (as defined in this Section  4.1) is an entity duly  incorporated,
validly  existing and in good standing under the laws of the jurisdiction of its
incorporation  and has the  corporate  power  and  authority  to own,  lease and
operate its  properties  and to conduct its  business as described in the Bergen
SEC Reports (as defined in Section  4.9.1).  Each of Bergen and each of Bergen's
Subsidiaries is duly qualified to transact business as a foreign  corporation or
other foreign entity and is in good standing in each  jurisdiction  in which the
conduct of its business or the  ownership,  leasing or operation of its property
requires such  qualification,  except for failures to be so qualified or in good
standing  which  would  not,  singly  or in the  aggregate  with all such  other
failures,  have a Bergen  Material  Adverse  Effect.  "Bergen  Material  Adverse
Effect" means, with respect to any event,  occurrence,  matter, failure of event
or occurrence,  change, effect, state of affairs,  breach,  default,  violation,
fine,  penalty or failure to comply (each, a  "Circumstance"),  individually  or
taken  together with all other  Circumstances  contemplated  by or in connection
with any or all of the representations and warranties made in this Agreement,  a
material adverse effect on the business,  assets (including  without  limitation
intangible assets),  liabilities (contingent or otherwise),  financial condition
or  results of  operations  of Bergen  and its  Subsidiaries,  taken as a whole;
provided,  however,  that Bergen Material  Adverse Effect shall not be deemed to
include  the  impact of: (A) any  decline  in the share  price of either  Bergen
Common Stock or PharMerica Common Stock,  except that any effect underlying such
decline shall be considered in  determining  whether a Bergen  Material  Adverse
Effect has  occurred  to the  extent  that such  effect  would  otherwise  be so
considered;  (B) the implementation of changes in generally accepted  accounting
principles;  (C) actions and  omissions of Bergen or its  Subsidiaries  taken or
permitted  with the prior written  consent of PharMerica  after the date hereof;
(D) expenses  reasonably  incurred by Bergen or its Subsidiaries in consummating
the  transactions  contemplated  by this  Agreement;  and (E) the  impact of the
implementation of the prospective  payment system for skilled nursing facilities
and  other  long  term  care   providers,   except  to  the  extent   that  such
implementation  would render  consummation of the  transactions  contemplated by
this  Agreement  illegal.  Neither  Bergen  nor  any of its  Subsidiaries  is in
violation of any of the provisions of its certificate of incorporation (or other
applicable charter document) or By-laws or, if it is a limited liability company
or  partnership,  its  operating  agreement,   partnership  agreement  or  other
comparable   agreement.   True  and  complete   copies  of  the  certificate  of
incorporation  and  By-laws,  as  currently  in  effect,  of  Bergen  have  been
previously  delivered or made  available to  PharMerica.  Except for  amendments
reflected in the Restated  Certificate  of  Incorporation  and by-laws of Bergen
heretofore  delivered to PharMerica and  amendments  described in Section 4.1 of
the Bergen Disclosure  Statement,  no amendments to the Restated  Certificate of
Incorporation,  as  amended,  and  By-laws,  as  amended,  of  Bergen  have been
authorized from September 30, 1998 through the date hereof. For purposes of this
Agreement,  all  references  to the  "Subsidiaries"  of Bergen shall  constitute
references  to any entity (i) the accounts of which would be  consolidated  with
those of Bergen in Bergen's consolidated  financial statements if such financial
statements  were  prepared in  accordance  with  generally  accepted  accounting
principles or (ii) of which securities or other ownership interests representing
more than 50% of the equity or more than 50% of the ordinary voting power or, in
the case of a partnership, more than 50% of the general partnership interests or
more than 50% of the  profits or losses  are owned by Bergen  and/or one or more
subsidiaries of Bergen.

          4.2 Authority Relative to This Agreement. Bergen and Subcorp each have
the  corporate  power and authority to execute and deliver this  Agreement  and,
upon  obtaining the requisite  approval of the holders of Bergen Common Stock at
the  Bergen  Annual  Meeting  or any  adjournment  thereof  with  respect to the
issuance of shares of Bergen Common Stock pursuant to the Merger,  to consummate
the Merger and the other  transactions  contemplated  hereby.  The execution and
delivery  of this  Agreement  and the  consummation  of the Merger and the other
transactions  contemplated  hereby have been duly and validly  authorized by the
Boards of Directors of Bergen and Subcorp and by Bergen as the sole  stockholder
of Subcorp,  and except as stated in the preceding sentence,  no other corporate
proceedings  on the part of Bergen or Subcorp are  necessary to  authorize  this
Agreement or to consummate  the Merger and the other  transactions  contemplated
hereby.  This  Agreement  has been duly and validly  executed  and  delivered by
Bergen and Subcorp and, assuming the due  authorization,  execution and delivery
hereof  by  PharMerica  and  subject  to  stockholder   approval  as  aforesaid,
constitutes  a valid and binding  agreement of Bergen and  Subcorp,  enforceable
against  Bergen and Subcorp in accordance  with its terms,  except to the extent
that its  enforceability  may be limited by applicable  bankruptcy,  insolvency,
reorganization, moratorium or other laws affecting the enforcement of creditors'
rights generally or by general equitable principles.

         4.3      Consents; No Conflicts.

               4.3.1 Except for actions to be taken in  connection  with (a) the
filing of the  Certificate of Merger,  (b) the filing and  effectiveness  of the
Registration  Statement,  (c) the filings  required under and in connection with
the applicable  requirements of the HSR Act, (d) any filings  required under the
New Jersey  Industrial Site Recovery Act, (e) filings  required  pursuant to any
state  securities or "blue sky" laws, (f) filings and other matters  relating to
the  listing  on the NYSE of the share of Bergen  Common  Stock  required  to be
issued  pursuant to this  Agreement,  (g) any filings,  notices,  disclosures or
registrations set forth in Section 4.3.1 of the PharMerica Disclosure Statement,
(h) such  reports  under  Section 13 of the  Exchange  Act as may be required in
connection  with  this  Agreement,   the  Merger  and  the  other   transactions
contemplated hereby and (i) other consents,  filings or notifications  which, if
not obtained or made, are not reasonably likely to have,  individually or in the
aggregate,  a Bergen Material  Adverse Effect,  no filing or registration  with,
notification or disclosure to, or permit, authorization, consent or approval of,
(x) any court, (y) any government agency or body or (z) any third party, whether
acting in an  individual,  fiduciary  or other  capacity,  is  required  for the
consummation  by  Bergen or  Subcorp  of the  Merger  or the other  transactions
contemplated hereby.

               4.3.2  Except  as set  forth  in  Section  4.3.2  of  the  Bergen
Disclosure Statement, the execution,  delivery and performance of this Agreement
and the  consummation  of the  Merger  and the other  transactions  contemplated
hereby and compliance by Bergen and Subcorp with any of the provisions hereof do
not and will not:  (i)  subject  to  obtaining  the  requisite  approval  of the
issuance of Bergen Common Stock  pursuant to the Merger by the holders of Bergen
Common  Stock,  conflict  with or  result  in any  breach  or  violation  of any
provision of the  certificate  of  incorporation  (or other  comparable  charter

Subsidiary of Bergen that is a limited  liability  company or  partnership,  its
operating agreement, partnership agreement or other comparable agreement or (ii)
result in (1) a breach or violation of, a default  under or an event  triggering
any  payment,  obligation  or  acceleration  of any  obligation  pursuant to any
existing pension plans,  welfare plans,  multiemployer  plans,  employee benefit
plans,  benefit  arrangements  or  similar  plans,   arrangements  or  policies,
including without  limitation bonus,  incentive,  deferred  compensation,  stock
purchase,  stock option,  stock appreciation  right,  health or group insurance,

the giving of notice or the lapse of time or both) pursuant to any provision of,
any  agreement,  lease  of  real  or  personal  property,  marketing  agreement,
contract, note, mortgage,  indenture or other obligation of Bergen or any of its
Subsidiaries   ("Bergen   Contracts")   or,   subject  to  making  all  filings,
notifications  and  disclosures  and  receipt  of all  permits,  authorizations,
consents and  approvals  referred to in clauses "a" through "i" of Section 4.3.1
or in Section 4.3.1 of the Bergen Disclosure Statement, any law, rule, ordinance
or regulation or judgment,  decree, order or award to which Bergen or any of its
Subsidiaries is subject or any governmental or  non-governmental  authorization,
consent, approval, registration, franchise, license or permit under which Bergen
or any of its Subsidiaries conducts any of its business, or (3) any other change
in the rights or  obligations  of any party  under any of the Bergen  Contracts,
except,  with respect to this clause (ii), for breaches,  violations,  defaults,
triggering  events,  creations of liens,  pledges,  security  interests or other
encumbrances  on assets,  or changes in rights or  obligations  which would not,
singly or in the aggregate with all other such matters,  have a Bergen  Material
Adverse Effect.

          4.4 Board  Recommendation.  The Board of Directors of Bergen has, by a
unanimous vote at a meeting of such Board duly held on January 8, 1999, approved
and adopted this Agreement,  the Merger and the other transactions  contemplated
hereby. At such meeting,  the Board of Directors of Bergen  recommended that the
holders of Bergen  Common  Stock  approve the  issuance of Bergen  Common  Stock
pursuant to this Agreement.

          4.5 No  Existing  Violation,  Default,  Etc.  None  of  Bergen  or its
Subsidiaries is in violation  (except for any violations which would not, singly
or in the  aggregate  with all such  other  violations,  have a Bergen  Material
Adverse  Effect) of (A) any Applicable Law or (B) any order,  decree or judgment
of any  Governmental  Authority  having  jurisdiction  over Bergen or any of its
Subsidiaries. No event of default or event that, but for the giving of notice or
the lapse of time or both,  would  constitute an event of default,  exists under
any  Bergen  Contract  or any  lease,  permit,  license  or other  agreement  or
instrument to which Bergen or any of its Subsidiaries is a party or by which any
of them is bound or to which  any of the  properties,  assets or  operations  of
Bergen or any of its  Subsidiaries  is subject (except for any events of default
or other  defaults  which would not,  singly or in the  aggregate  with all such
other defaults, have a Bergen Material Adverse Effect).

          4.6 Licenses and Permits. Each of Bergen and its Subsidiaries has such
certificates,   permits,  licenses,  franchises,  consents,  approvals,  orders,
authorizations and clearances from appropriate  governmental agencies and bodies
("Bergen Licenses") as are necessary to own, lease or operate its properties and
to conduct its business in the manner described in the Bergen SEC Reports and as
presently conducted and all such Bergen Licenses are valid and in full force and
effect, other than any failure to have any such Bergen License or any failure of
any such  Bergen  License to be valid and in full force and effect as would not,
singly or in the aggregate with all such other failures,  have a Bergen Material
Adverse Effect. Each of Bergen and its Subsidiaries is and, within the period of
all  applicable  statutes  of  limitations,  has  been in  compliance  with  its
obligations under such Bergen Licenses and no event has occurred that allows, or
after notice or lapse of time would allow,  revocation  or  termination  of such
Bergen  Licenses,  other  than any such  failure to be in  compliance  with such
obligations or any such revocation or termination as would not, singly or in the
aggregate  with all such other  failures,  revocations or  terminations,  have a
Bergen  Material  Adverse  Effect.  Bergen  has no  knowledge  of any  facts  or
circumstances  that could  reasonably  be expected to result in an  inability of
Bergen or any of its  Subsidiaries to renew any Bergen  License,  other than any
such  non-renewal  as  would  not,  singly  or in the  aggregate  with  all such
non-renewals,  have a Bergen  Material  Adverse  Effect.  Subject  to making all
filings,   notifications   and   disclosures   and   receipt  of  all   permits,
authorizations,  consents  and  approvals  referred  to in Section  4.3.1 of the
Bergen  Disclosure  Statement,  neither the  execution and delivery by Bergen or
Subcorp  of this  Agreement  nor  the  consummation  of any of the  transactions
contemplated herein will result in any revocation or termination of any material
Bergen License.

          4.7 Registration Statement;  Prospectus/Joint Proxy Statement. None of
the information supplied by Bergen for inclusion in, and none of the information
regarding  Bergen  and  its  Subsidiaries  incorporated  by  reference  in,  the
Registration  Statement or the Prospectus/Joint  Proxy Statement,  including all
amendments  and  supplements  thereto,  shall,  in the case of the  Registration
Statement, at the time the Registration Statement becomes effective, and, in the
case  of  the  Prospectus/Joint  Proxy  Statement,  on the  date  or  dates  the
Prospectus/Joint  Proxy  Statement  is first  mailed  to Bergen  and  PharMerica
stockholders  and on the date or  dates of the  Bergen  Annual  Meeting  and the
PharMerica  Special Meeting,  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 the light of the circumstances  under
which  they were  made,  not  misleading.  The  Registration  Statement  and the
Prospectus/Joint Proxy Statement will comply as to form in all material respects
with the  applicable  provisions of the  Securities Act and the Exchange Act, as
the case may be.

          4.8 Finders or Brokers; Compensation Arrangements. Except as set forth
in  Section  4.8 of the  Bergen  Disclosure  Statement,  neither  Bergen nor any
Subsidiary  of Bergen has  employed any  investment  banker,  broker,  finder or
intermediary in connection with the transactions  contemplated  hereby who might
be entitled to a fee or any  commission  the receipt of which is  conditioned in
whole or part upon consummation of the Merger. The compensation payable by or on
behalf  of  Bergen  and  its  Subsidiaries  (with  respect  to the  transactions
contemplated  hereby) to any investment banker,  broker,  finder or intermediary
identified in Section 4.8 of the Bergen Disclosure Statement is set forth in one
or more  engagement  letters  delivered to PharMerica  prior to the execution of
this Agreement.

          4.9 SEC Filings.

               4.9.1  Bergen has, in all material  respects,  filed with the SEC
all required  forms,  reports and documents  required to be filed by it with the
SEC since December 31, 1994  (collectively,  the "Bergen SEC  Reports"),  all of
which, when filed (in the case of forms, reports and documents filed pursuant to
the  Exchange  Act) or when  declared  effective  (in the  case of  registration
statements  filed  pursuant to the Securities  Act),  complied as to form in all
material  respects with the applicable  provisions of the Securities Act and the
Exchange Act, as the case may be. As of their  respective  dates, the Bergen SEC
Reports  (including  documents  included as exhibits  thereto or incorporated by
reference  therein) did not contain any untrue  statement of a material  fact or
omit to state a material fact required to be stated therein or necessary to make
the  statements  therein,  in light of the  circumstances  under which they were
made, not misleading.

               4.9.2  Bergen will deliver to  PharMerica  as soon as they become
available true and complete  copies of any report or statement  mailed by Bergen
to its  security  holders  generally  or filed by it with the SEC,  in each case
subsequent  to the date  hereof  and prior to the  Effective  Time.  As of their
respective dates, such reports and statements (excluding any information therein
provided by PharMerica,  as to which Bergen makes no representation) will comply
as to form in all  material  respects  with  the  applicable  provisions  of the
Securities Act and the Exchange Act, will not contain any untrue  statement of a
material fact or omit to state a material fact required to be stated  therein or
necessary to make the statements  therein,  in light of the circumstances  under
which they are made,  not  misleading,  and will further  comply in all material
respects with all applicable  requirements  of law,  except for such failures to
comply as to form,  untrue statements or omissions or further failures to comply
which would not be reasonably likely to have,  individually or in the aggregate,
a Bergen Material Adverse Effect. The audited consolidated  financial statements
and  unaudited  consolidated  interim  financial  statements  of Bergen  and its
Subsidiaries  to be included or  incorporated  by  reference in such reports and
statements  will be prepared in accordance  with generally  accepted  accounting
principles applied on a consistent basis throughout the periods involved (except
as  may  be  indicated  in the  notes  to  such  financial  statements),  and in
accordance  with all  applicable  published  accounting  requirements  under the
Securities  Act and the Exchange  Act,  and will fairly  present in all material
respects the consolidated  financial  position of Bergen and its Subsidiaries as
of the dates thereof and the consolidated results of operations and consolidated
cash flows of Bergen and its  Subsidiaries  for the periods then ended (subject,
in the case of any unaudited  interim financial  statements,  to normal year-end
adjustments  and to the extent  that they may not  include  footnotes  or may be
condensed  or  summary  statements);  provided,  however,  that  any  pro  forma
financial  statements  will not  necessarily  be indicative of the  consolidated
financial  position  of  Bergen  as of the  respective  dates  thereof  and  the
consolidated  results of  operations  and cash  flows of Bergen for the  periods
indicated.

          4.10 Financial  Statements.  Bergen's  audited  consolidated  year-end
financial  statements  and Bergen's  unaudited  consolidated  interim  financial
statements  included or incorporated by reference in the Bergen SEC Reports have
been  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 to such financial statements), and in accordance with all
applicable  published  accounting  requirements under the Securities Act and the
Exchange  Act,  and fairly  present in all material  respects  the  consolidated
financial position of the entities described therein as of the dates thereof and
the  consolidated  results of  operations  and  consolidated  cash flows of such
entities  for the  periods  then ended  (subject,  in the case of any  unaudited
interim financial  statements,  to normal year-end adjustments and to the extent
they may not  include  footnotes  or may be  condensed  or summary  statements);
provided,  however, that any pro forma financial statements will not necessarily
be  indicative  of the  consolidated  financial  position  of  Bergen  as of the
respective  dates thereof and the  consolidated  results of operations  and cash
flows of Bergen for the periods indicated.

          4.11 Absence of Changes.  Since  September  30,  1998,  except for (a)
matters publicly disclosed by Bergen prior to the date hereof (including without
limitation  matters  disclosed  in Bergen SEC  Reports  filed  prior to the date
hereof)  and (b)  matters  disclosed  in Section  4.13 of the Bergen  Disclosure
Statement,  there  has been no  event or  condition  which  has  caused a Bergen
Material Adverse Effect,  nor any  development,  occurrence or state of facts or
circumstances known to Bergen that could, singly or in the aggregate, reasonably
be expected to result in a Bergen Material Adverse Effect.

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 Bergen Common Stock has not

Stock or any other equity  securities of Bergen or any  securities  representing
the right to purchase or otherwise  receive any shares of Bergen Common Stock or
Bergen Preferred Stock or any other equity securities of Bergen.

no material pending actions, suits,  proceedings or, to the knowledge of Bergen,
investigations  by, against or affecting Bergen,  any of its Subsidiaries or any
of their  properties,  assets or operations,  or with respect to which Bergen or
any of its  Subsidiaries is responsible by way of indemnity or otherwise,  which
would,  singly  or  in  the  aggregate  with  all  such  other  actions,  suits,

Subsidiary  has set aside on its books  adequate  reserves  in  accordance  with
generally accepted  accounting  principles;  (iii) in the case of real property,

the value or use of the real property  encumbered  thereby as currently  used in
the  operation of the business of Bergen or its  Subsidiaries;  (iv) those which
would not  materially  interfere  with the conduct of the business of Bergen and

this  Agreement  and to consummate  the  transactions  contemplated  hereby (the

collectively,   the  "Bergen  Permitted   Encumbrances");   (v)  those  securing

material respects,  prepared and timely filed or will, in all material respects,
timely file with the appropriate governmental agencies all franchise, income and
all other Tax  returns  and  reports  (hereinafter  collectively  referred to as

Subsidiaries  have been paid in full to the proper  authorities or fully accrued
or provided  for with  respect to fiscal  periods  for which there are  publicly

accounting  principles or are not material to Bergen and its Subsidiaries  taken
as a whole;  (iii)  all  deficiencies  asserted  in  writing  as a result of Tax
examinations of federal,  state and foreign income,  sales and franchise and all
other Tax Returns  filed by Bergen and its  Subsidiaries  have,  in all material

knowledge of Bergen,  no unpaid deficiency has been asserted or assessed against
Bergen or any of its  Subsidiaries,  and no  examination of Bergen or any of its
Subsidiaries  is pending or  threatened,  for any material  amount of Tax by any
taxing authority.

          4.16  Absence  of  Undisclosed  Liabilities.  As of the  date  hereof,
neither Bergen nor any of its Subsidiaries has any liabilities or obligations of
any nature, whether absolute,  accrued,  unmatured,  contingent or otherwise, or
any  unsatisfied  judgments or any leases of  personalty or realty or unusual or
extraordinary commitments,  except for those liabilities or allowances recorded,
accrued or reserved  against on the Bergen  Balance Sheet (as defined in Section
4.14) or described in the notes thereto,  except for  liabilities or obligations
that would not,  singly or in the  aggregate,  be reasonably  expected to have a
Bergen  Material  Adverse Effect and except for those  liabilities  described in
Section 4.16 of the Bergen Disclosure Statement.

confidentiality  agreement,  Bergen  shall (a)  provide  complete  and  accurate
information  to  PharMerica  and its  representatives  in response to reasonable

particular  date) and the fulfillment of the covenants of this Article V and the
closing  conditions  in  Sections  6.1 and 6.3 and (b)  furnish to  PharMerica's
financial advisor complete and accurate  information  comparable to the types of
information  heretofore furnished by Bergen to PharMerica's financial advisor in
connection with the transactions  contemplated hereby and such other information

the  destruction  thereof to PharMerica and (b) PharMerica will return to Bergen
all documents  obtained by it from Bergen and its Subsidiaries in confidence and
any  copies   thereof  in  the  possession  of  PharMerica  or  its  agents  and
representatives  or, at the option of PharMerica,  PharMerica shall cause all of
such  documents  and all of such copies to be  destroyed  and shall  certify the
destruction  thereof  to  Bergen.  No  investigation  by  Bergen  or  PharMerica
heretofore or hereafter made shall modify or otherwise  affect the conditions to
the  obligation  of  Bergen  and  PharMerica  to  consummate  the   transactions
contemplated hereby.

otherwise  expressly  provided  herein,  PharMerica  shall (and PharMerica shall

close to be satisfied; and

consummation of the Closing, to its knowledge (a) any of the representations and
warranties  contained  in Article III cease to be accurate  and  complete in all
material  respects  (except for any  representation  and  warranty  (i) which is
qualified  hereunder as to materiality,  as to which such notification  shall be
given  if   PharMerica  or  its   Subsidiaries   obtain   knowledge   that  such
representation and warranty is inaccurate in any respect, or (ii) that addresses
matters only as of a particular  date, which need only be true and correct as of
such  date) or 4(b)  PharMerica  fails to comply  with or satisfy  any  material
covenant,  condition  or  agreement  to be  complied  with  or  satisfied  by it
hereunder;  provided,  however, that the delivery of any notice pursuant to this

hereunder to Bergen.

otherwise  expressly provided herein,  Bergen shall (and Bergen shall cause each
of its Subsidiaries to):

               5.3.4  use   commercially   reasonable   efforts  to  obtain  all
authorizations,  consents,  waivers,  approvals or other actions and to make all
filings and  applications  necessary or desirable to consummate the transactions
contemplated hereby and to cause the other conditions to PharMerica's obligation
to close to be satisfied; and

               5.3.5  promptly  notify  PharMerica  in writing if,  prior to the
consummation of the Closing, to its knowledge (a) any of the representations and
warranties  contained  in Article IV cease to be  accurate  and  complete in all
material  respects  (except for any  representation  and  warranty  (i) which is
qualified  hereunder as to materiality,  as to which such notification  shall be
given if Bergen or its Subsidiaries  obtain  knowledge that such  representation
and warranty is inaccurate in any respect,  or (ii) that addresses  matters only
as of a particular date, which need only be true and correct as of such date) or
(b) Bergen fails to comply with or satisfy any material  covenant,  condition or
agreement to be complied with or satisfied by it hereunder;  provided,  however,
that the delivery of any notice  pursuant to this Section  5.3.5 shall not limit
or otherwise affect the remedies available hereunder to PharMerica.

          5.4 PharMerica's Negative Covenants. Prior to the Closing, without the
prior  written  consent of Bergen or as  otherwise  expressly  provided  herein,
PharMerica will not and PharMerica will cause its Subsidiaries not to:

               5.4.1  take any  action or omit to take any  action  which  would
result in  PharMerica's  or any of its  Subsidiaries'  (a)  incurring  any trade

practice); (g) entering into or amending any collective bargaining agreement, or
creating  or  modifying  any pension or  profit-sharing  plan,  bonus,  deferred

excess of $10,000,000 in the aggregate;  (l) except for PharMerica  Common Stock
issuable  upon  exercise of a  PharMerica  Stock  Option or  PharMerica  Warrant
outstanding on December 31, 1998, issuing any shares of the capital stock of any
kind of  PharMerica  or its  Subsidiaries,  transferring  from the  treasury  of
PharMerica or its  Subsidiaries any shares of the capital stock of PharMerica or
its  Subsidiaries  or issuing or granting any  subscriptions,  options,  rights,

issue, or to transfer from treasury, any shares of capital stock of any class or

terminating any material  PharMerica  Contract other than in the ordinary course
of business that is  consistent  with past  practices;  or (n) entering into any
other transaction outside of the ordinary course of business;

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

               5.4.3  take  any  action   that  would   likely   result  in  the
representations   and   warranties   set  forth  in  Article   III  (other  than
representations  made as of a particular  date)  becoming false or inaccurate in
any material respect (or, as to representations and warranties,  which, by their
terms,  are  qualified as to  materiality,  becoming  false or inaccurate in any
respect);

               5.4.4  incur  or  create  any  encumbrances,  liens,  pledges  or
security interests on assets other than PharMerica Permitted Encumbrances;

               5.4.5 except as contemplated  herein,  take any action or omit to
take any action which would materially  interfere with Bergen's rights to compel
performance of each of the obligations of PharMerica under this Agreement;

               5.4.6 take or omit to be taken any  action,  or permit any of its
affiliates  to take or to omit to take any  action,  which would  reasonably  be
expected to result in a PharMerica Material Adverse Effect;

               5.4.7  amend or  modify,  or  propose  to amend  or  modify,  the
PharMerica Rights Agreement, as amended as of the date hereof; or

Section 5.4.

          5.5 Bergen's  Negative  Covenants.  Prior to the Closing,  without the
prior written consent of PharMerica or as otherwise  expressly  provided herein,
Bergen will not and Bergen will cause its Subsidiaries not to:

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

               5.5.2  take  any  action   that  would   likely   result  in  the
representations   and   warranties   set  forth  in  Article   IV  (other   than
representations  made as of a particular  date)  becoming false or inaccurate in
any material respect (or, as to representations and warranties,  which, by their
terms,  are  qualified as to  materiality,  becoming  false or inaccurate in any
respect);

               5.5.3 except as contemplated  herein,  take any action or omit to
take any action which would  materially  interfere with  PharMerica's  rights to
compel performance of each of the obligations of Bergen under this Agreement;

               5.5.4 take or omit to be taken any  action,  or permit any of its
affiliates  to take or to omit to take any  action,  which would  reasonably  be
expected to result in a Bergen Material Adverse Effect;

               5.5.5 amend Bergen's  Restated  Certificate of  Incorporation  or
by-laws in any material  manner that does not generally apply to all of Bergens
stockholders; or

               5.5.6  agree or  commit  to take  any  action  precluded  by this
Section 5.5.

          5.6 Closing  Documents.  PharMerica shall,  prior to or on the Closing
Date, execute and deliver, or cause to be executed and delivered,  to Bergen the
documents or instruments  described in Section 6.2. Bergen shall, prior to or on
the Closing Date, execute and deliver, or cause to be executed and delivered, to
PharMerica the documents or instruments described in Section 6.3.

         5.7      HSR Act.

               5.7.1 Each of Bergen and PharMerica shall (A) make or cause to be
made the filings required of such party or any of its subsidiaries or affiliates
under  the HSR Act with  respect  to the  transactions  contemplated  hereby  as
promptly as  practicable  and in any event within five  business  days after the
date of this  Agreement,  (B) comply at the earliest  practicable  date with any
request  under  the HSR Act for  additional  information,  documents,  or  other
materials  received  by such party or any of its  subsidiaries  from the Federal
Trade  Commission  or  the  Department  of  Justice  or any  other  Governmental
Authority in respect of such  filings or such  transactions,  and (C)  cooperate
with the other  party in  connection  with any such  filing  (including  without
limitation  the exchange  between the  parties,  or where  prudent,  between the
outside  counsel of the parties,  of relevant  materials  prior to the filing of
such  materials,  provided that nothing  herein shall obligate a party hereto to
waive attorney-client protections or similar protections,  and, if requested, to
accept all reasonable  additions,  deletions or changes  suggested in connection
therewith) and in connection with resolving any  investigation  or other inquiry
of any such agency or other Governmental  Authority under any Antitrust Laws (as
hereinafter  defined)  with respect to any such filing or any such  transaction.
Each  party  shall use all  reasonable  efforts  to  furnish  to each  other all
information  required for any application or other filing to be made pursuant to
any  Applicable  Law in  connection  with the Merger and the other  transactions
contemplated by this Agreement. Each party shall promptly inform the other party
of any  communication  with,  and any proposed  understanding,  undertaking,  or
agreement  with, any  Governmental  Authority  regarding any such filings or any
such transaction.  Neither party shall  independently  participate in any formal
meeting with any Governmental Authority in respect of any filing,  investigation
or other  inquiry  relating to the Merger  without  giving the other party prior
notice  of the  meeting  and,  to the  extent  permitted  by  such  Governmental
Authority, the opportunity to attend and/or participate. The parties hereto will
consult  and  cooperate  with one  another,  in  connection  with any  analyses,
appearances, presentations, memoranda, briefs, arguments, opinions and proposals
made or  submitted  by or on  behalf  of any party  hereto  in  connection  with
proceedings  relating  to the Merger  under or  relating to the HSR Act or other
Antitrust Laws.

               5.7.2  Each of Bergen  and  PharMerica  shall use all  reasonable
efforts  to  resolve  such  objections,  if  any,  as  may  be  asserted  by any
Governmental  Authority with respect to the  transactions  contemplated  by this
Agreement under the HSR Act, the Clayton Act, as amended,  the Sherman Antitrust
Act, as amended,  the Federal Trade  Commission  Act, as amended,  and any other
federal,  state  or  foreign  statues,  rules,  regulations,   orders,  decrees,
guidelines, administrative or judicial doctrines or other laws that are designed
to  prohibit,  restrict  or  regulate  actions  having the  purpose or effect of
monopolization  or restraint of trade or competition  (collectively,  "Antitrust
Laws").   In  connection   therewith  and  subject  to  Section  5.7.3,  if  any
administrative  or judicial action or proceeding is instituted (or threatened to
be instituted)  challenging  any  transaction  contemplated by this Agreement as
violative of any Antitrust  Law, each of Bergen and PharMerica  shall  cooperate
and use all reasonable  efforts vigorously to contest and resist any such action
or proceeding,  including without limitation any legislative,  administrative or
judicial  action,  and to have vacated,  lifted,  reversed,  or  overturned  any
decree,  judgment,  injunction or other order whether temporary,  preliminary or
permanent (each an "Order"), that is in effect and that prohibits,  prevents, or
restricts  consummation of the Merger or any other transactions  contemplated by
this  Agreement,  including,  without  limitation,  by  vigorously  pursuing all
available  avenues of  administrative  and  judicial  appeal  and all  available
legislative action, unless by mutual agreement Bergen and PharMerica decide that
any such action is not in their respective best interests.  Notwithstanding  the
foregoing or any other provision of this Agreement,  nothing in this Section 5.7
shall limit a party's right to terminate this Agreement pursuant to Section 7.1,
so long as such party has up to then complied in all material  respects with its
obligations  under this Section 5.7. Each of Bergen and PharMerica shall use all
reasonable  efforts to take such  action as may be  required  to cause the early
termination  or  expiration  of the waiting  periods  under the HSR Act or other
Antitrust Laws with respect to such  transactions  as promptly as possible after
the execution of this Agreement.

               5.7.3 If required to avoid a Governmental  Authority  instituting
an action challenging the transactions  contemplated by this Agreement under the
Antitrust Laws and seeking to enjoin or prohibit the  consummation of any of the
transactions  contemplated  by this Agreement (or if required to settle any such
action previously instituted by a Governmental Authority), Bergen shall, and, at
the direction of Bergen,  PharMerica shall,  propose,  negotiate,  commit to and
effect,  by  consent  decree,  hold  separate  order,  or  otherwise,  the sale,
divestiture or disposition of any of their respective  businesses or assets,  or
take or agree to take any action or agree to any  limitation  as may be required
in order to avoid the entry of, or to effect the dissolution of, any injunction,
temporary  restraining  order or other  order in any suit or  proceeding,  which
would otherwise have the effect of preventing or delaying the Closing; provided,
however,  that this Section 5.7.3 shall not require Bergen to take any action if
such action, in the reasonable judgment of Bergen's Board of Directors, would be
reasonably  likely to have a Bergen Material  Adverse Effect after the Effective
Time giving effect to  consummation  of the  transactions  contemplated  by this
Agreement.

          5.8  Further  Actions.  Each of the parties  hereto  agrees to use all
reasonable  efforts to take,  or cause to be taken,  all actions,  and to do, or
cause to be done,  and to assist and cooperate  with the other parties in doing,
all things necessary,  proper or advisable to consummate and make effective,  in
the most  expeditious  manner  practicable  in light of the  circumstances,  the
Merger and the other  transactions  contemplated  by this  Agreement,  including
without  limitation  (A)  the  obtaining  of  all  other  necessary  actions  or
nonactions,  waivers, consents,  licenses, permits,  authorizations,  orders and
approvals from  Governmental  Authorities  and the making of all other necessary
registrations  and  filings,  (B) the  obtaining of all  consents,  approvals or
waivers from third parties  related to or required in connection with the Merger
that are necessary to consummate the Merger and the transactions contemplated by
this  Agreement  or required to prevent a Bergen  Material  Adverse  Effect or a
PharMerica  Material  Adverse  Effect  from  occurring  prior  to or  after  the
Effective Time, (C) the preparation of the Prospectus/Joint  Proxy Statement and
the Registration Statement, the declaration of effectiveness of the Registration
Statement by the SEC and the mailing of the Prospectus/Joint  Proxy Statement to
the  stockholders of Bergen and PharMerica,  (D) if necessary as a result of the
circumstances,  the amendment of the Registration Statement and Prospectus/Joint
Proxy  Statement as required by law,  (E) the taking of all action  necessary to
ensure that the Merger constitutes a tax-free  reorganization within the meaning
of Section  368(a)(1)(A)  of the Code, and (F) the execution and delivery of any
additional instruments necessary to consummate the transactions contemplated by,
and to fully carry out the purposes of, this Agreement.

          5.9 Employment  Agreement.  Prior to execution of this Agreement,  the
officer  of  PharMerica  identified  in  Section  5.9 of the  Bergen  Disclosure
Statement has executed an employment agreement (the "New Employment Agreement").
PharMerica  shall not amend or modify the New Employment  Agreement at or before
the Effective Time.

          5.10 Public  Announcements.  Unless  otherwise  required by Applicable
Laws or  requirements of the NYSE or Nasdaq (and in that event only if time does
not  permit),  at all  times  prior  to the  earlier  of the  Effective  Time or
termination  of this  Agreement  pursuant to Section 7.1,  Bergen and PharMerica
shall  consult with each other before  issuing any press release with respect to
the  Merger  and  shall  not  issue  any  such  press   release  prior  to  such
consultation.

          5.11. Stockholders' Meetings.

               5.11.1  Bergen  Annual  Meeting.  Subject to Article VII,  Bergen
shall take all action in accordance  with the federal  securities  law,, the New
Jersey   Business   Corporations   Act,   Bergen's   Restated   Certificate   of
Incorporation,  as amended,  and  Bergen's  by-laws,  as amended,  necessary  to
convene the Bergen Annual  Meeting to be held on the earliest  practical date as
reasonably determined by Bergen in light of the circumstances, and to obtain the
consent and  approval of Bergen's  stockholders  with respect to the issuance of
Bergen  Common  Stock  pursuant  to the  Merger,  including  (in the  absence of
conditions that would justify the  termination of this  Agreement)  recommending
such approval to Bergen's stockholders.

               5.11.2 PharMerica  Special Meeting.  Subject to Sections 5.17 and
5.18 and Article VII,  PharMerica  shall take all action in accordance  with the
federal securities laws, the DGCL, PharMerica's Certificate of Incorporation, as
amended,  and  PharMerica's  by-laws,  as  amended,  necessary  to  convene  the
PharMerica  Special  Meeting  to be  held  on the  earliest  practical  date  as
reasonably determined by Bergen in light of the circumstances, and to obtain the
consent and approval of PharMerica's stockholders with respect to this Agreement
and  the  transactions   contemplated  hereby,  including  (in  the  absence  of
conditions that would justify the  termination of this  Agreement)  recommending
such approval to PharMerica's stockholders.

          5.12  Preparation of the  Joint/Proxy  Statement and the  Registration
Statement.  Bergen  shall,  as soon as is  reasonably  practicable,  prepare the
Prospectus/Joint  Proxy Statement to be included in the Registration  Statement.
Once both parties consent to the filing of the Prospectus/Joint  Proxy Statement
with the SEC (which consent shall not be  unreasonably  withheld),  Bergen shall
file the  Prospectus/Joint  Proxy  Statement with the SEC, which filing shall be
made on a confidential  basis to the extent  permitted by the regulations of the
SEC with  respect  to such  filings.  Consistent  with the timing for the Bergen
Annual  Meeting and the  PharMerica  Special  Meeting as determined by Bergen in
accordance with Section 5.11, Bergen shall, subject to the consent of PharMerica
(which shall not be unreasonably  withheld),  prepare and file the  Registration
Statement with the SEC as soon as is reasonably  practicable following clearance
of the  Prospectus/Joint  Proxy Statement by the SEC and reasonable  approval of
the Prospectus/Joint  Proxy Statement by PharMerica and Bergen and shall use all
reasonable efforts to have the Registration  Statement declared effective by the
SEC as promptly as practicable  thereafter and to maintain the  effectiveness of
the Registration  Statement through the Effective Time. If, at any time prior to
the  Effective  Time,  Bergen  or  PharMerica  shall  obtain  knowledge  of  any
information  contained in or omitted from the Registration  Statement that would
require  an  amendment  or  supplement  to  the  Registration  Statement  or the
Prospectus/Joint  Proxy  Statement,  the party  obtaining  such  knowledge  will
promptly  so advise the other party in writing  and both  PharMerica  and Bergen
will promptly  take such action as shall be required to amend or supplement  the
Registration Statement and/or the Prospectus/Joint  Proxy Statement.  PharMerica
shall promptly furnish to Bergen all financial and other information  concerning
it as  may  be  required  for  the  Prospectus/Joint  Proxy  Statement  and  any
supplements or amendments thereto.  Bergen and PharMerica shall cooperate in the
preparation  of the  Prospectus/Joint  Proxy  Statement in a timely  fashion and
shall use all reasonable efforts to clear the  Prospectus/Joint  Proxy Statement
and the  Registration  Statement  with the Staff of the SEC.  Promptly after the
Registration  Statement is declared effective by the SEC, each of PharMerica and
Bergen shall use all reasonable efforts to mail at the earliest practicable date
to its stockholders the  Prospectus/Joint  Proxy Statement,  which shall include
all  information  required under  Applicable Law to be furnished to PharMerica's
stockholders  and Bergen's  stockholders  in connection  with the Merger and the
transactions  contemplated  thereby  and  shall  include  the  PharMerica  Board
Recommendation to the extent not previously withdrawn in compliance with Section
5.17  and  the  written  opinion  of  Donaldson  Lufkin  &  Jenrette  Securities
Corporation  described  in  Section  7.1.8.  Bergen  also  shall take such other
reasonable  actions (other than qualifying to do business in any jurisdiction in
which it is not so qualified or  submitting to taxation in any  jurisdiction  in
which it is not subject to taxation)  required to be taken under any  applicable
state  securities laws in connection with the issuance of Bergen Common Stock in
the Merger.  Notwithstanding any provision herein to the contrary,  prior to the
time that the Registration Statement is declared effective, the Prospectus/Joint
Proxy  Statement  shall contain the audited  consolidated  financial  statements
described in clause "a" of Section 5.22.1.

          5.13 Indemnification; Directors' and Officers' Insurance.

               5.13.1 From and after the Effective  Time, to the fullest  extent
permitted by law, Bergen shall  indemnify,  defend and hold harmless the present
and former  officers and directors of PharMerica in respect of acts or omissions
occurring  prior  to the  Effective  Time  to the  fullest  extent  provided  or
permitted  under  PharMerica's  Certificate  of  Incorporation,  as amended  and
restated  through the date  hereof,  and  PharMerica's  By-laws,  as amended and
restated through the date hereof.  Notwithstanding  the foregoing,  Bergen shall
not be liable for any  settlement  relating to such acts or  omissions  effected
without Bergen's prior written consent,  which consent shall not be unreasonably
withheld.

               5.13.2  Bergen  shall  use all  reasonable  efforts  to cause the
Surviving Corporation or Bergen to obtain and maintain in effect for a period of
six years  after  the  Effective  Time  policies  of  directors'  and  officers'
liability insurance at no cost to the beneficiaries thereof with respect to acts
or omissions  occurring prior to the Effective Time with  substantially the same
coverage and containing  substantially similar terms and conditions as currently
existing policies maintained by PharMerica;  provided, however, that neither the
Surviving  Corporation  nor Bergen  shall be required  to pay an annual  premium
during such six-year period for such insurance coverage in excess of 150% of the
annual premium currently paid for such insurance by PharMerica.

               5.13.3  Bergen  covenants and agrees from and after the Effective
Time to provide to the directors of PharMerica,  if any, who become directors of
Bergen directors' and officers' liability insurance on the same basis and to the
same extent as that, if any, provided to other directors of Bergen.

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

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

          5.16 Employees and Employee  Benefits.  Following the Effective  Time,
Bergen shall provide  generally to officers and employees of PharMerica  and its
Subsidiaries employee benefits under employee benefit and welfare plans on terms
and conditions which are  substantially  similar to those provided by PharMerica
and its  Subsidiaries  on the date hereof.  From and after the  Effective  Time,
Bergen shall treat all service by PharMerica  Employees (as defined  below) with
PharMerica and its Subsidiaries and their respective  predecessors  prior to the
Effective  Time for all  purposes as service  with Bergen  (except to the extent
such treatment would result in duplicative  accrual on or after the Closing Date
of benefits for the same period of service), and, with respect to any medical or
dental  benefit  plan  in  which  PharMerica  Employees  participate  after  the
Effective  Time,  Bergen  shall  waive or cause to be  waived  any  pre-existing
condition exclusions and actively-at-work  requirements (provided, however, that
no such  waiver  shall  apply  to a  pre-existing  condition  of any  PharMerica
Employee who was, as of the Effective  Time,  excluded from  participation  in a
PharMerica  Benefit Plan by virtue of such  pre-existing  condition),  and shall
provide that any covered expenses  incurred on or before the Effective Time by a
PharMerica Employee or a PharMerica  Employee's covered dependent shall be taken
into account for purposes of satisfying applicable  deductible,  coinsurance and
maximum out-of-pocket  provisions after the Effective Time to the same extent as
such  expenses  are taken into  account  for the benefit of  similarly  situated
employees  of Bergen and  subsidiaries  of Bergen.  For purposes of this Section
5.16,  "PharMerica  Employees"  shall mean persons who are, as of the  Effective
Time,  employees of PharMerica or its Subsidiaries.  Bergen also shall cause the
Surviving  Corporation  and its  Subsidiaries  to honor in accordance with their
terms all employment,  severance,  consulting and other  compensation  contracts
disclosed  in  Section  3.23  of the  PharMerica  Disclosure  Statement  between
PharMerica  or one of its  Subsidiaries  and any  current  of  former  director,
officer,  or employee  thereof,  and all provisions for vested benefits or other
vested amounts earned or accrued through the Effective Time under the provisions
of  the  PharMerica  Employee  Benefit  Plans  listed  in  Section  3.26  of the
PharMerica Disclosure Statement as such provisions exist on the date hereof.

          5.17   No   Solicitation;   Withdrawal   of   the   PharMerica   Board
Recommendation.

               5.17.1 PharMerica 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,  directly or  indirectly,  to solicit,  initiate,  encourage or
facilitate, or furnish or disclose non-public information in furtherance of, any
inquiries  or the making of any proposal  with respect to any  recapitalization,
merger,  consolidation or other business combination  involving  PharMerica,  or
acquisition  of any capital  stock of  PharMerica  (other than upon  exercise of
PharMerica  Options or PharMerica  Warrants which are outstanding as of the date
hereof) or 20% or more of the assets of PharMerica and its  Subsidiaries,  taken
as a whole, in a single transaction or a series of related transactions,  or any
acquisition  by PharMerica 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 Bergen, Subcorp or their respective directors,  officers, employees, agents
and representatives) with respect to any Competing Transaction or enter into any
agreement,  arrangement or understanding  requiring it to abandon,  terminate or
fail to consummate  the Merger or any other  transactions  contemplated  by this
Agreement;  provided  that,  at any time prior to the  approval of the Merger by
PharMerica' stockholders,  PharMerica 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
PharMerica determines, in good faith by a majority vote, after consultation with
its financial  advisors and  consultation and receipt of advice from its outside
legal counsel, that failing to take such action (i.e.,  furnishing  information,
negotiating  and engaging in  discussions,  as aforesaid)  would be inconsistent
with  the  fiduciary  duties  of the  Board of  Directors  of  PharMerica  under
Applicable  Law.  PharMerica  will  immediately  cease all existing  activities,
discussions and negotiations with any parties conducted  heretofore with respect
to any proposal for a Competing Transaction.

               5 17.2  Notwithstanding any other provision of this Section 5.17,
in  the  event  that,  prior  to the  approval  of the  Merger  by  PharMerica's
stockholders,  the Board of Directors of PharMerica determines, in response to a
written  proposal  for a  Competing  Transaction  which  was  not  solicited  or
encouraged  after the date of this Agreement,  such  determination to be in good
faith by a majority  vote after  consultation  with its  financial  advisors and
consultation  and  receipt of advice from its outside  legal  counsel,  that its
failure to withdraw,  modify or change the PharMerica Board Recommendation would
be inconsistent  with the fiduciary  duties of the PharMerica Board of Directors
under  Applicable  Law, the Board of Directors of PharMerica may (subject to the
provisions of this Section 5.17) withdraw, modify or change, in a manner adverse
to Bergen,  the PharMerica Board  Recommendation  and, to the extent applicable,
comply with Rule 14e-2  promulgated  under the  Exchange  Act with  respect to a
Competing  Transaction  by  disclosing  such  withdrawn,   modified  or  changed
PharMerica  Board  Recommendation  in connection with a tender or exchange offer
for PharMerica  securities,  provided that  PharMerica (i) provides  Bergen with
written notice of (A) its intention to withdraw, modify or change the PharMerica
Board  Recommendation  and  (B)  the  terms  and  conditions  of  any  Competing
Transaction  at least  48  hours  prior  to any  termination  of this  Agreement
pursuant  to this  Section  5.17 (it  being  understood  that  once 48 hours has
elapsed  since  PharMerica's  first  notice to Bergen of its intent to withdraw,
modify or change the PharMerica  Board  Recommendation,  PharMerica  may, in its
discretion, terminate this Agreement pursuant to this Section 5.17 regardless of
any response by Bergen to such notice if such  termination is in accordance with
the provisions of this Section 5.17, and (ii) delivers to Bergen concurrent with
such  withdrawal,  modification or change (A) a written notice of termination of
this  Agreement  pursuant to this  Section  5.17,  (B) a payment in cash by wire
transfer in immediately  available  funds to an account  designated by Bergen in
the amount of Bergen' Costs (as hereinafter  defined) as the same may have been
estimated by Bergen in good faith prior to the date of such delivery (subject to
an adjustment payment between the parties upon Bergen's definitive determination
of such (costs), and a payment in cash by wire transfer in immediately available
funds to an account designated by Bergen in the amount of the termination fee as
provided in Section 7.2 and (C) a written  acknowledgment  from  PharMerica that
upon  termination of this  Agreement  pursuant to this Section 5.17, the amended
and restated  Bergen  Supply  Agreement  described in Section  7.2.2 shall be in
effect,  shall be binding upon  PharMerica  and its  successors  and assigns and
shall be honored in accordance  with its terms.  The  foregoing  shall in no way
limit or otherwise affect Bergen's right to terminate this Agreement pursuant to
Section 7.1.4.  The PharMerica  Board of Directors  shall not take any action to
change the  approval of the Board of  Directors  of  PharMerica  for purposes of
causing any state  takeover  statute or other state law to be  applicable to the
transactions  contemplated hereby,  including the Merger,  unless and until this
Agreement is terminated.

               5.17.3 From and after the execution of this Agreement, PharMerica
shall,  as  promptly as  possible  and in any event  within 24 hours of receipt,
advise  Bergen  in  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 Bergen 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,  PharMerica shall immediately  advise Bergen, in
writing, if the Board of Directors of PharMerica shall make any determination as
to any  Competing  Transaction  as  contemplated  by the  proviso  to the  first
sentence of Section 5.17.1.

          5.18  Termination  Right.  If,  prior to the approval of the Merger by
PharMerica's  stockholders,  the Board of Directors of PharMerica determines, in
response  to a  written  proposal  for a  Competing  Transaction  which  was not
solicited or encouraged after the date of this Agreement,  such determination to
be in good  faith by a  majority  vote  after  consultation  with its  financial
advisors and  consultation  and receipt of advice from is outside legal counsel,
that it must withdraw, modify or change the PharMerica Board Recommendation (all
in accordance with and in compliance with Section 5.17) and that a failure to do
so would be inconsistent  with the fiduciary duties of the Board of Directors of
PharMerica  under  Applicable  Law, then if PharMerica has complied with each of
the  provisions  of  Section  5.17  (including  without  limitation  each of the
provisions of Section 5.17.2),  it 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.

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

          5.20 Subsequent  Financial  Statements.  PharMerica shall consult with
Bergen prior to making publicly  available its financial  results for any period
after the date of this  Agreement and prior to filing any PharMerica SEC Reports
after the date of this Agreement.

          5.21 Environmental  Matters.  Prior to the Closing,  Bergen shall have
the right,  at its expense,  to make such  environmental  studies of each of the
premises  at  which  PharMerica  and  its  Subsidiaries  conduct  business  (the
"Premises"),  including without  limitation  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 PharMerica
and its Subsidiaries  harmless from any loss, cost or damage  proximately caused
by such  inspection.  Such inspection shall be scheduled and performed so as not
to unreasonably interfere with the business of PharMerica and its Subsidiaries.

          5.22 Financial Statements for a Current Report on Form 8-K.

               5.22.1 Prior to the Closing,  PharMerica  shall provide to Bergen
(a)  regardless of when the Closing  occurs,  (i) audited  consolidated  balance
sheets of PharMerica and its Subsidiaries as of December 31, 1998 and 1997, (ii)
audited   consolidated   statements  of  income,   cash  flows  and  changes  in
shareholders'  equity of  PharMerica  and its  Subsidiaries  for the years ended
December 31, 1998,  1997 and 1996, and (iii) an unqualified  report with respect
to such audited financial  statements by Arthur Andersen & Co. LLP, which report
shall be in form and substance reasonably satisfactory to Bergen, and (b) if the
Closing occurs on or after May 14, 1999, in addition to the items referred to in
clause "a" of this Section 5.22.1, (i) unaudited  consolidated balance sheets of
PharMerica and its Subsidiaries as of March 31, 1999 and 1998 and (ii) unaudited
consolidated  statements  of  income,  cash flows and  changes in  shareholders'
equity of PharMerica and its  Subsidiaries  for the three months ended March 31,
1999 and 1998.  Such financial  statements  shall be prepared in accordance with
generally  accepted  accounting  principles,  consistently  applied,  and  shall
conform in all material  respects to all provisions of the SEC's Regulation S-X,
so that such financial  statements  meet the  requirements  for filing by Bergen
with the SEC in  response to Items 2 and 7 of the SEC's  Current  Report on Form
8-K.

               5.22.2 At the Closing,  PharMerica  shall cause Arthur Andersen &
Co.  LLP to  deliver  to  Bergen  an  executed  consent,  in form and  substance
reasonably  satisfactory  to Bergen and  suitable  for filing by Bergen with the
SEC,  which  consent  shall  authorize  Bergen to file  with the SEC the  report
delivered pursuant to Section 5.22.1.

               5.22.3 Upon Bergen's request,  contemporaneous  with the delivery
of the  consolidated  financial  statements  described  in clause "a" of Section
5.22.1,  PharMerica  shall cause Arthur  Andersen & Co. LLP to make available to
Bergen and its representatives the work papers generated in connection with such
accounting  firm's  audit  of  the  audited  consolidated  financial  statements
delivered pursuant to Section 5.22.1.

               5.22.4  Prior to the Closing,  PharMerica  shall  cooperate  with
Bergen in providing to Bergen such consolidated financial statements,  financial
data and accountants' reports as Bergen shall reasonably request with respect to
any filing that Bergen shall make under the Securities Act or the Exchange Act.

          5.23  Tax-Free  Treatment.  Each of the  parties  shall  use its  best
efforts to cause the Merger to  constitute  a  tax-free  "reorganization"  under
Section  368(a) of the Code and to  cooperate  with one another in  obtaining an
opinion from Lowenstein Sandler PC ("Lowenstein Sandler"), counsel to Bergen, as
provided  for in Section  6.1.6.  In  connection  therewith,  each of Bergen and
PharMerica  shall  deliver to  Lowenstein  Sandler  representation  letters  and
PharMerica  shall use all reasonable  efforts to obtain  representation  letters
from  appropriate  stockholders of PharMerica and shall deliver any such letters
so obtained to Lowenstein Sandler, in each case in form and substance reasonably
satisfactory to Lowenstein Sandler.  Each of Bergen and PharMerica represent one
to the other that they are aware of no matter that would cause the Merger not to
be treated as a tax free reorganization under Section 368(a) of the Code.

          5.24  Employee  Stock  Purchase  Plans.  Consistent  with the terms of
PharMerica's   stock  purchase  plans,   promptly  following  the  date  hereof,
PharMerica  shall take such actions as are  necessary to provide that (a) shares
sold to plan  participants  pursuant to such plans subsequent to the date hereof
shall be purchased by  PharMerica  or its agent in the market,  (b) at or before
the Effective Time, the amount of all payroll deduction  contributions then held
in each participant's plan account shall be returned to such participant and (c)
as of the Effective Time, such plans shall be terminated.

contemplated by this Agreement.

               6.1.3  The  waiting  period  required  by the  HSR  Act,  and any

          7.1. Termination.  This Agreement may be terminated and the Merger may

stockholders):

               7.1.1 by mutual written consent of Bergen and PharMerica;

               7.1.2 by either Bergen or PharMerica if there shall be any law or
regulation  that, as supported by the written  opinion of outside legal counsel,
makes  consummation  of the Merger  illegal or otherwise  prohibited,  or if any
judgment, injunction, order or decree of a court or other competent Governmental
Authority enjoining Bergen or PharMerica from consummating the Merger shall have
been entered and such  judgment,  injunction,  order or decree shall have become
final and nonappealable;

               7.1.3 by either Bergen or PharMerica if the Merger shall not have
been  consummated  before the Outside Date (as hereinafter  defined),  provided,
however,  that the right to terminate  this  Agreement  under this Section 7.1.3
shall not be available to any party whose failure or whose  affiliate's  failure
to perform any material covenant or obligation under this Agreement has been the
cause of or  resulted  in the  failure of the Merger to occur on or before  such
date;

               7.1.4 by Bergen if the Board of  Directors  of  PharMerica  shall
withdraw,  modify or change  the  PharMerica  Board  Recommendation  in a manner
adverse to Bergen;

               7.1.6 by either  Bergen or  PharMerica  if at the  Bergen  Annual
Meeting  (including any adjournment or postponement  thereof) the requisite vote
(under  all  Applicable  Laws and the  rules  and  regulations  of the  NYSE) of
Bergen's  stockholders  to authorize  the issuance of Bergen Common Stock in the
Merger shall not have been obtained;

               7.1.7 by PharMerica, pursuant to Section 5.17 or Section 5.18;

               7.1.8 by PharMerica if (a) Donaldson Lufkin & Jenrette Securities

standards  consistent with prior practices,  declines to provide PharMerica with
an  opinion,   in  substantially  the  form  and  substance  of,  and  based  on
substantially  the same  analyses  as were  utilized in  preparing,  the opinion
described  in  Section  3.30,  to  the  effect  that,  as of  the  date  of  any
Prospectus/Joint   Proxy  Statement,   the  Merger   Consideration  is  fair  to
PharMerica's  stockholders from a financial point of view and (b) an independent
investment banking firm,  mutually acceptable to Bergen and PharMerica (a "Third
Party  Firm"),  after  being  given  a  reasonable   opportunity  to  perform  a
satisfactory  inquiry,  advises Bergen and PharMerica that, acting in good faith
and in accordance with recognized  professional  standards consistent with prior
practices,  it is unable to  provide  PharMerica  with an  opinion,  in form and
substance  consistent with industry  practice to the effect that, as of the date
of any  Prospectus/Joint  Proxy Statement,  the Merger  Consideration is fair to
PharMerica's  stockholders  from a financial point of view; or by Bergen, if (c)
Nationsbanc  Montgomery  Securities  LLC, acting in good faith and in accordance
with recognized professional standards consistent with prior practices, declines
to provide Bergen with an opinion,  in substantially  the form and substance of,
and based on substantially the same analyses as were utilized in preparing,  the
opinion  delivered by such firm in connection  with  Bergen's  execution of this
Agreement,  to the effect  that,  as of the date of any  Prospectus/Joint  Proxy
Statement,  the Merger Consideration is fair to Bergen from a financial point of
view, and (d) a Third Party Firm, after being given a reasonable  opportunity to
perform a satisfactory  inquiry,  advises Bergen and PharMerica that,  acting in
good faith and in accordance with recognized  professional  standards consistent
with prior  practices,  it is unable to provide Bergen with an opinion,  in form
and substance  consistent  with industry  practice to the effect that, as of the
date of any Prospectus/Joint  Proxy Statement,  the Merger Consideration is fair
to Bergen from a financial point of view.

               7.1.9 by either  Bergen or PharMerica  if any  representation  or
warranty made in this  Agreement  (including  without  limitation the PharMerica
Disclosure  Statement and the Bergen  Disclosure  Statement)  for its benefit is
untrue in any material respect (other than  representations and warranties which
are qualified as to materiality,  which representations and warranties will give
rise to termination if untrue in any respect);  provided that, in each case, (a)
the party seeking to terminate this Agreement is not then in material  breach of
any material  representation or warranty  contained in this Agreement,  (b) such
untrue representation or warranty cannot be or has not been cured within 30 days
after  receipt  of  written  notice  of  such  breach  and  (c) in the  case  of
PharMerica,  except for the representations and warranties contained in Sections
3.1,  3.2,  3.5  and  3.14,   and  in  the  case  of  Bergen,   except  for  the
representations  and  warranties  contained in Sections 4.1, 4.2 and 4.12,  such
untrue  representation  and  warranty  has, or is  reasonably  likely to have, a
PharMerica  Material Adverse Effect or a Bergen Material Adverse Effect,  as the
case may be and in each case after the Effective Time and after giving effect to
consummation of the transactions contemplated by this Agreement;

               7.1.10 by either  Bergen or  PharMerica  if the other party shall
have defaulted in the  performance of any material  covenant or agreement  under
this Agreement;  provided that, in each case, (a) the party seeking to terminate
this  Agreement  has  complied  with its  covenants  and  agreements  under this
Agreement in all material  respects and (b) such failure to comply  cannot be or
has not been  cured  within 30 days  after  receipt  of  written  notice of such
default;

               7.1.11  by  Bergen  if  any  authorization,  consent,  waiver  or
approval required for the consummation of the transactions  contemplated  hereby
shall  require the  divestiture  or cessation of any of the present  business or
operations  conducted  by  Bergen  or  its  Subsidiaries  or  PharMerica  or its
Subsidiaries or shall impose any other material condition or requirement,  which
divestiture,  cessation, condition or requirement, in the reasonable judgment of
Bergen's  Board  of  Directors,  would  be  reasonably  likely  to have a Bergen
Material  Adverse Effect after the Effective Time giving effect to  consummation
of the  transactions  contemplated by this Agreement,  except to the extent that
any such divestiture, cessation, condition or requirement is consistent with the
obligations of Bergen and PharMerica pursuant to Section 5.7.3;

               7.1.12  by  Bergen,  in the  event  that  the  conditions  to its
obligations  set forth in  Article VI have not been  satisfied  or waived by the
date set for the Closing or in the event that such conditions cannot possibly be
satisfied  prior  to the  Outside  Date,  provided  that  Bergen  is not then in
material  breach of any  material  representation,  warranty,  covenant or other
agreement contained in this Agreement; or

               7.1.13 by  PharMerica,  in the event that the  conditions  to its
obligations  set forth in  Article VI have not been  satisfied  or waived by the
date set for the Closing or in the event that such conditions cannot possibly be
satisfied  prior to the Outside Date,  provided  that  PharMerica is not then in
material  breach of any  material  representation,  warranty,  covenant or other
agreement contained in this Agreement.

For purposes of this Agreement,  the "Outside Date" shall mean (a) June 1, 1999,
or,  (b) if a Third  Party Firm (as  defined  herein) is  retained  pursuant  to
Section 7.1.8, then July 1, 1999.

          7.2. Effect of Termination.

confidentiality  obligations  of the  parties  hereto  to  each  other  and  the

     stockholders to so approve this Agreement there is a publicly  announced or

     third party,  and (C) within 12 months after such  termination,  PharMerica
     shall enter into an Acquisition  Agreement for a Business  Combination  (as

described in Section  7.2.2.4 has been  disclosed to  PharMerica  at the time of
such  termination,  prior  to the  earlier  of the  consummation  of a  Business

following steps (the "Contingency Steps") will occur: (1) PharMerica will pay to
Bergen in cash by wire  transfer in  immediately  available  funds to an account
designated  by Bergen (i) in  reimbursement  for Bergen's  expenses an amount in
cash equal to the aggregate  amount of Bergen's Costs up to but not in excess of
