               PHARMACEUTICAL RESOURCES ANNOUNCES SAWYER TO RETIRE

SPRING VALLEY, NEW YORK, JUNE 19, 2003 - Pharmaceutical Resources, Inc.
(NYSE:PRX) today announced that Kenneth I. Sawyer, chairman, president and chief
executive officer, plans to retire, effective July 1, 2003. Sawyer, who has led
the company since 1989, will devote much of his time and efforts to managing the
Landon Morley Sawyer Foundation, a charitable foundation established in 2002.

The board of directors will conduct a search for a new chairman and chief
executive officer of PRX. In the interim, Scott Tarriff, president and chief
executive officer of PRX's Par Pharmaceutical subsidiary, and Arie L. Gutman,
Ph.D., president and chief executive officer of PRX's FineTech unit, will report
to the company's lead outside director. During this transition, Mr. Sawyer will
remain a director and be available to consult with the company.

"Our company has never been stronger or more successful, so, after almost 14
years, I've decided it is the ideal time, both personally and professionally, to
retire from PRX. I now look forward to the opportunity to pursue those personal
interests that are of great importance to me," said Sawyer. "We have just
completed the most successful year in our history, having achieved record sales
and earnings, and look forward to 2003 being even better. We have succeeded in
building a strong business that has propelled us into the ranks of the fastest
growing generic pharmaceutical companies. Most importantly, with a talented and
experienced management team in place, I am confident that the substantial
progress we have achieved together will continue. My decision to retire at the
end of June reflects my confidence in the future of PRX."

In October 1989, Sawyer became president and chief executive officer of the
company and was named chairman of the board in October 1990. Over the past two
years, PRX's sales have grown almost 350 percent with record sales and earnings
achieved in each of the last two years. Since 2001, PRX, or its partners, has
launched many new products, including six drugs with first-to-file status. PRX
currently has over 40 drugs in development and 26 Abbreviated New Drug
Applications (ANDA) awaiting approval at the U.S. Food and Drug Administration.
These ANDAs include as many as 5 that may represent first-to-file opportunities
entitling the company, or its strategic partner, up to 180 days of marketing
exclusivity or co-exclusivity.

Earlier this year, PRX was included in the Standard & Poor's (S&P) MidCap 400
Index, which measures the performance of the mid-size company segment of the
U.S. equity market. This index is used by over 95 percent of U.S. portfolio
managers and pension plan sponsors with more than $25 billion indexed to the S&P
MidCap 400.



On behalf of his fellow board members, Mark Auerbach, a director since 1990,
said, "we are grateful to Ken for his many contributions to PRX and his
sacrifices in its behalf over the years. We wish Ken all the best and
congratulate him on his record of achievement."
