Item 1.  Change of Control.
- -------  ------------------

         Introduction

          On June 30, 1998 (the "Closing Date"), Pharmaceutical Resources, Inc.,
a New Jersey corporation (the "Company" or the "Registrant"), completed the sale
of 10,400,000  shares (the  "Shares") of the Company's  common stock,  par value
$.01 per share  (the  "Common  Stock"),  to Lipha  Americas,  Inc.,  a  Delaware
corporation  ("Lipha"),  at a price of $2.00  per  share or  $20,800,000  in the
aggregate.  Also on the Closing Date, the Company issued options (the "Options")
to purchase up to an aggregate of 1,171,040  shares of Common Stock (the "Option
Shares")  at an  exercise  price of $2.00  per share to Merck  KGaA,  Darmstadt,
Germany, a Kommanditgesellschaft  auf Aktien organized under the laws of Germany
("Merck  KGaA"),  and Genpharm  Inc., a Canadian  corporation  ("Genpharm"),  in
exchange for certain services to be provided to the Company.  Lipha and Genpharm
are subsidiaries of Merck KGaA.  Simultaneously  with the sale of the Shares and
the issuance of the Options,  Merck KGaA  purchased  1,813,272  shares of Common
Stock from Clal Pharmaceutical  Industries Ltd. ("Clal").  Such transactions and
certain  related   transactions  are  referred  to  in  this  Form  8-K  as  the
"Transaction."

         Immediately  following  the  closing  of the  Transaction,  Merck  KGaA
beneficially  owned  approximately 42% of the outstanding Common Stock. If Merck
KGaA and its  affiliates  exercise the Options and Merck KGaA acquires from Clal
an  additional  500,000  shares of Common  stock it has rights to in the future,
Merck KGaA would  beneficially own approximately  46% of the outstanding  Common
Stock.  Through its subsidiary  Lipha,  Merck KGaA  designated a majority of the
directors on the Company's  Board of  Directors.  As a result of its large stock
ownership and ability to appoint directors of the Company,  Merck KGaA is likely
to be able to exercise control over matters requiring shareholder approval.  The
Company  believes that the source of funds for the purchase price for the Shares
and the shares  purchased  from Clal was the working  capital of Lipha and Merck
KGaA.

         The following is a description  of certain terms of the Stock  Purchase
Agreement,  dated  March 25,  1998,  between  the  Company and Lipha (the "Stock
Purchase  Agreement")  and related  agreements.  Such agreements are attached to
this  Form 8-K as  exhibits.  The  following  description  of the  terms of such
agreements is qualified in their entirety by reference to such exhibits.

         General

         Stock  Purchase  Agreement.  On the Closing  Date,  the Company sold to
Lipha the Shares at an aggregate purchase price of $20,800,000 in cash, or $2.00
per Share.  The closing price of the Common Stock on The New York Stock Exchange
on March 25, 1998, the day the Stock Purchase Agreement was executed, was $2.625
per share.  The Shares are not  registered  under the Securities Act of 1933, as
amended (the "Securities Act"). However, Lipha has certain demand and piggy-back
registration  rights with  respect to the  Shares.  See  "--Registration  Rights
Agreement"  below. The Stock Purchase  Agreement  contains  certain  significant
terms,  obligations  and other  agreements,  as described  below,  including the
obligation  to grant and issue the  Options  in return  for the right to receive
certain  services,  Lipha's  right to designate a majority of the members of the
Company's  Board of Directors (the  "Board"),  Lipha's right of first refusal in
respect of certain  equity  offerings,  and Lipha's  agreement  not to engage in
certain extraordinary transactions.

         Board  Representation.  Lipha has the right to  designate a majority of
the members of the Board.  Pursuant to this right, Lipha has designated Bernhard
Scheuble,  Anthony S.  Tabatznik,  J. Neil  Tabatznik  and Klaus  Jander.  Three

                                      -2-


members of the Board are comprised of Kenneth I. Sawyer, the Chairman, President
and Chief Executive Officer of the Company,  and two additional designees of the
Board prior to the consummation of the Stock Purchase  Agreement  (collectively,
the "Company  Designees").  Mark Auerbach and Stephen A.  Ollendorff are the two
other  Company  Designees.  All of such seven  persons  have been elected by the
shareholders  at the Annual Meeting of  Shareholders of the Company held on June
26, 1998 (the "Annual Meeting").  In addition,  Lipha has the right to designate
(i) jointly with the Company Designees, two members of the Board to comprise the
Audit Committee of the Board and (ii) the President and Chief Operating  Officer
of the  Company.  Mr.  Sawyer  will  continue  to serve as  Chairman  and  Chief
Executive  Officer of the  Company  and each of its  subsidiaries  upon  Lipha's
designation of a President.  The effect of the foregoing  agreement is to afford
voting  control to the designees of Lipha with respect to matters  determined by
the Board.

         Mr. J. Neil  Tabatznik,  a director of the Company,  is the Chairman of
Genpharm, which will develop, manufacture and distribute products to the Company
pursuant  to the  Distribution  Agreement,  dated  March 25,  1998,  between the
Company  and  Genpharm  (the  "Distribution  Agreement").   See  "--Distribution
Agreement"  below.  Mr. Anthony S.  Tabatznik,  a director of the Company,  is a
board member of Merck Pharma which  controls the  pharmaceutical  operations  of
Merck  KGaA,  including  Genpharm.  Dr.  Bernhard  Scheuble,  a director  of the
Company,  is Deputy Member of the Executive Board of Merck KGaA. The Company and
Genpharm and its  affiliate  are presently  parties to  distribution  agreements
entered into in 1992 and 1993. Under such distribution  agreements,  payments by
the Company to Genpharm and an affiliate in fiscal year 1997  accounted for less
than five percent of the Company's and Genpharm's  consolidated  gross revenues.
However,  in fiscal  year 1998,  it is  expected  that,  under the  Distribution
Agreement  and the other  distribution  agreements,  payments  by the Company to
Genpharm  and  its  affiliate   would  exceed  five  percent  of  the  Company's
consolidated gross revenues.

         Right of First Refusal. Lipha has a right of first refusal for a period
of six years  following the Closing Date to purchase all, but not less than all,
of any equity  securities  to be sold by the Company  pursuant  to any  proposed
non-registered  offering or any  registered  offering  solely for cash. If Lipha
does not exercise  its first  refusal  rights  within 30 days of notice from the
Company,   the  Company  may  sell  such   securities  to  any  third  party  on
substantially  the same terms and  conditions  as first  offered  to Lipha.  The
Shares and the Option Shares do not have any preemptive rights.

         Limitations on Related Party  Transactions  and Business  Combinations;
Lock-up.  Lipha has agreed,  for a period of three years  following  the Closing
Date, not to cause or permit the Company to engage in any  transactions or enter
into any  agreements or  arrangements  with, or make any  distributions  to, any
Affiliate  or Associate  (each as defined in the Stock  Purchase  Agreement)  of
Lipha without the prior written consent of a majority of the Company  Designees.
In addition, Lipha has agreed, for a period of three years following the Closing
Date,  not to propose  that the  Company,  or to cause or permit the Company to,
engage in business combinations or other extraordinary  transactions,  including
mergers and tender  offers,  without the prior written  consent of a majority of
the  Company  Designees  and the prior  receipt  of a fairness  opinion  from an
independent nationally recognized investment bank.

         As a condition to the closing of the Stock Purchase Agreement,  certain
holders of options to purchase Common Stock, including Mr. Sawyer, and the other
executive officers of the Company, have agreed not to exercise their options for
a period of three  years and 10 days from the  Closing  Date and  certain  other
holders,  including the non-employee  directors of the Company immediately prior
to the Closing Date,  have agreed not to exercise  more than  one-third of their
options annually commencing on the first anniversary of the Closing Date.

                                      -3-


         Merck KGaA and the Company have  reached an agreement in principle  for
Merck KGaA to prepay in full a promissory note of a subsidiary of the Company in
the  principal  amount of $600,000 on behalf of such  subsidiary in exchange for
consideration  relating to the Company's  Israel-based  research and development
facility to be agreed upon in the future.

         Distribution   Agreement.   In  connection   with  the  Stock  Purchase
Agreement,  Genpharm and the Company have entered into a Distribution Agreement,
dated March 25, 1998 (the "Distribution  Agreement")  pursuant to which Genpharm
granted  exclusive  distribution  rights to the Company within the United States
and certain  other U.S.  territories  with respect to  approximately  40 generic
pharmaceutical  products  currently under  development or being sold by Genpharm
and its  affiliates  outside of the United  States.  Products may be added to or
removed  from the  Distribution  Agreement  by mutual  agreement of the parties.
Genpharm  is  required  to use  commercially  reasonable  efforts to develop the
products which are subject to the Distribution  Agreement and is responsible for
the  completion  of  product   development  and  for  obtaining  all  applicable
regulatory  approvals.  The  Company  will pay  Genpharm a  percentage  of gross
profits  attributable to sales of such products.  

         Services  Agreements.  On the  Closing  Date,  each of  Merck  KGaA and
Genpharm entered into separate  Services  Agreements to provide various services
to the  Company  for a period  of 36  months,  including,  but not  limited  to,
rendering advice and providing  technical support and assistance in the areas of
research and development, regulatory compliance,  manufacturing, quality control
and quality assurance,  administration,  marketing and promotion  (collectively,
the "Services").  In consideration of providing the Services, the Company issued
on the Closing Date, an Option to Merck KGaA to purchase up to 820,000 shares of
Common  Stock and an Option to  Genpharm  to  purchase  up to 351,040  shares of
Common Stock.

         Options.  The Options entitle Merck KGaA and Genpharm to purchase up to
an aggregate of 1,171,040  Option Shares at an exercise price of $2.00 per share
with  one-third of the total Option Shares  vesting  annually  commencing on the
first  anniversary of the Closing Date. The Options are  exercisable at any time
beginning three years and 10 days following the Closing Date and will terminate,
to the extent  unexercised,  on April 30, 2003. The Options  contain  provisions
that protect the holder against dilution by adjustment of the exercise price and
the number of Option Shares  issuable upon exercise in certain  events,  such as
stock  dividends,  stock  splits,  consolidation,  merger,  or  sale  of  all or
substantially  all of the  Company's  assets.  The holders of the Options do not
have any rights as shareholders of the Company unless and until the Options have
been exercised. The Options are not and the Option Shares will not be registered
under the Securities Act. However,  the Option Shares may be registered upon the
exercise of  registration  rights by the holders of the  Options  and/or  Option
Shares pursuant to certain demand and piggy-back  registration  rights under the
Registration Rights Agreement described below.

         Clal Sale Agreement.  Pursuant to a letter  agreement,  dated March 25,
1998 (the "Clal Sale Agreement"), between the Company, Merck KGaA and Clal, Clal
sold to Lipha on the Closing  Date,  an aggregate of 1,813,272  shares of Common
Stock at a price of $2.00 per share. Pursuant to the Clal Sale Agreement,  Merck
KGaA  agreed to pay Clal,  on the second  anniversary  of the Closing  Date,  an
amount equal to the excess, if any, of the weighted average trading price of all
trades in shares of Common  Stock on The New York Stock  Exchange  during the 30
trading days preceding such date over $2.00, multiplied by 500,000. In addition,
Clal has the right to cause Merck KGaA  and/or the  Company to  purchase  Clal's

                                      -4-


remaining  500,000 shares of Common Stock during the five-day period  commencing
three years and five days after the Closing Date, in certain circumstances, at a
price of $2.50 per share. If Clal does not exercise such right,  then Merck KGaA
and the  Company  have the right to cause Clal to sell its  remaining  shares in
open market  transactions and Merck KGaA and the Company will purchase from Clal
all shares  which have not been sold within 90 days.  The shares of Common Stock
to be purchased  from Clal under the Clal Sale  Agreement are referred to herein
as the "Clal Shares." Clal has agreed,  for the  three-year and five-day  period
following the Closing Date, not to acquire or sell, directly or indirectly,  any
shares of Common Stock,  other than pursuant to the Clal Sale  Agreement,  enter
into any agreement with respect to the voting,  holding or  transferring  of any
shares  of  Common  Stock  or to  propose  or  participate  in any  transactions
involving the Company or recommend  others to take any of such  actions.  All of
Clal's rights under the Stock Purchase Agreement,  dated March 25, 1995, between
the Company and Clal,  including the right to appoint  directors of the Company,
terminated on the Closing Date.

         Registration  Rights  Agreement.  In  consideration  of the  rights and
benefits  obtained by the Company  under the Stock  Purchase  Agreement  and the
services  that  will  be  provided  to the  Company  pursuant  to  the  Services
Agreements,  the Company,  on the Closing Date, granted to Lipha, Merck KGaA and
Genpharm  (collectively,  the  "Holders")  certain  registration  rights under a
registration rights agreement (the "Registration Rights Agreement"). In general,
the Holders will not be able to freely sell the Shares, the Option Shares or the
Clal Shares (collectively,  the "Registrable Shares") without registration under
applicable   securities  laws  or  unless  an  exemption  from  registration  is
available.

         Starting  nine months  after the  Closing  Date,  the  Holders  will be
entitled to three demand  registrations of Registrable Shares and two additional
demand registrations if the Options are exercised. In addition, the Holders have
the right to register the  Registrable  Shares on each occasion that the Company
registers shares of Common Stock, subject to certain limitations and exceptions.
If the  Company  at any time  registers  shares of Common  Stock for sale to the
public, the Holders have agreed not to sell publicly, make any short sale, grant
any option for the purchase of or otherwise publicly dispose of shares of Common
Stock during the same period during which  directors  and executive  officers of
the Company are similarly limited in selling the Company's  securities up to 180
days after the effective date of the applicable registration statement.

         Amendment to Certificate of Incorporation

         At the Annual  Meeting,  the  shareholders  of the Company  approved an
amendment  to  Article  IV of the  Company's  Certificate  of  Incorporation  to
increase  the  authorized  number of shares of Common Stock from  60,000,000  to
90,000,000  (the  "Common  Stock  Amendment").  The purpose of the Common  Stock
Amendment is to provide  additional  shares of Common Stock for the consummation
of the  Transaction  and for other  valid  corporate  purposes  without  further
shareholder approval unless required by applicable law or regulation. The Common
Stock Amendment was  filed with the Secretary of State of New Jersey on June 26,
1998, a copy of which is attached as an exhibit to this Form 8-K.

         1997 Directors Stock Option Plan

         At the Annual Meeting,  the  shareholders  of the Company  approved the
Company's 1997 Directors Stock Option Plan (the "Directors  Plan").  The Company
has reserved  for issuance  under the  Directors  Plan 500,000  shares of Common
Stock. Options granted under the Directors Plan may be granted only to directors
of the Company who are not  employees  of the Company or  otherwise  eligible to
receive  options  under any other  plan  adopted by the  Company.  A copy of the
Directors  Plan is attached as an exhibit to this Form 8-K.  The 1995  Directors
Stock Option Plan terminated upon shareholder  approval of the Directors Plan at
the Annual Meeting.  A total of 100,000 shares of Common Stock were reserved and
available for issuance under the 1995 Directors Stock Option Plan.
