Barr's Second Quarter Fiscal 2004 GAAP Earnings of $0.49 Per Share Driven by 79%
Increase in Revenues

Excluding Write-off of Acquired In-Process R&D, Second Quarter Earnings Were
$0.81 Per Share

Woodcliff Lake, NJ - February 5, 2004... Barr Pharmaceuticals, Inc. (NYSE-BRL)
today reported that revenues increased 79% to $374.1 million for the second
quarter of fiscal 2004, ended December 31, 2003, compared to $209.0 million for
the same period last year. Net earnings for the quarter were $35.1 million, or
$0.49 per share on a fully diluted basis, compared to $42.7 million, or $0.62
per fully diluted share for the same period last year. The quarter results
include an after-tax charge of $0.32 per fully diluted share related to a $35.6
million write-off of acquired in-process research and development representing
the purchase price of the assets of Endeavor Pharmaceuticals, Inc. Excluding
this item, adjusted earnings for the quarter would have been $0.81 per fully
diluted share.

For the first six months, revenues increased 59% to $684.8 million, compared to
$429.5 million in the prior year period. Net earnings were $73.6 million, or
$1.04 per share on a fully diluted basis, compared to net earnings of $84.6
million, or $1.24 per share on a fully diluted basis in the prior year period.
In the first six months, the Company's results included the charge of $0.32 per
fully diluted share related to the write-off acquired of in-process research
and development costs discussed above and a charge of $0.14 per fully diluted
share taken in the first quarter of fiscal 2004 related to the establishment of
a $15.7 million reserve against loans and accrued interest owed to Barr by
Natural Biologics, LLC. Excluding these items, adjusted earnings per fully
diluted share for the first six months would have been $1.50.

A reconciliation of GAAP-based earnings per fully diluted share to adjusted
non-GAAP earnings per share is presented in a table at the end of this press
release.

"Continued strong sales of our distributed Ciprofloxacin product, sales from new
product launches, including our Mirtazapine Orally Disintegrating Tablet and
Tri-Sprintec(R) oral contraceptive products, and higher sales of our expanding
oral contraceptive franchise, which now totals 18 products, drove an outstanding
quarter," said Bruce L. Downey, Barr's Chairman and CEO. "Our strong revenue
growth more than offset our significant investment in R&D and our increased
sales and marketing costs associated with the mid-November launch of our
SEASONALE(R) extended-cycle oral contraceptive."

"We are very pleased that our launch of SEASONALE(R) has been well received by
the medical community and has generated excitement among consumers," continued
Downey. "The early prescription data for SEASONALE is promising and we remain
committed to an extensive educational and promotional campaign to healthcare
providers and consumers that we believe will complement the already high
awareness of the product."

Revenues

Product Sales

Total product sales for the quarter increased 78% to $369.9 million, compared to
$207.7 million in the prior year period. For the first six months, total product
sales increased 59% to $678.6 million, compared to $426.4 million for the prior
year period. Sales of the Company's distributed Ciprofloxacin product, an
antibiotic that the Company launched on June 9, 2003, contributed $145.4 million
to product sales during the quarter.

Sales of the Company's generic oral contraceptive product portfolio increased
39% to $98.5 million for the quarter, compared to $71.0 million for the prior
year period. Contributing to this increase were higher sales of the Company's
in-line generic oral contraceptive franchise and sales from the Company's
Tri-Sprintec(R) oral contraceptive that was launched during the quarter.

Sales of Cenestin(R) (Synthetic Conjugated Estrogens, A), Barr's estrogen-only
conjugated estrogen product, were $14.2 million for the quarter, as compared to
$12.6 million in the prior year period.

Development and Other Revenue

The Company reported development and other revenue of $4.3 million for the
quarter, compared to $1.4 million in the prior year quarter. For the first six
months, development and other revenue totaled $6.2 million, compared to $3.1
million in the prior year period. Development revenues in the quarter rose
compared to the prior year primarily due to higher reimbursable R&D costs for
products currently in development, including the Company's Adenovirus vaccine
product.

Margins

Margins on product sales for the quarter were 43.8%, compared to 54.3% in the
prior year period. Contributing to the decline was a higher percentage of sales
from the Company's distributed Ciprofloxacin product and a pre-tax charge of
approximately $4.0 million related to a write-down of fixed assets in the
Company's Pomona, New York and Cincinnati, Ohio manufacturing facilities
primarily related to renovations to these facilities and to changes in the
estimated useful lives of certain building improvements. Ciprofloxacin, as both
a distributed product and a product subject to a profit split with a partner,
carries a lower margin than the Company's other products, which continued to
contribute margins in the mid-60% range during the quarter, up slightly as
compared to the same period last year.

Research and Development

R&D expenses were $63.1 million for the quarter, compared to $22.4 million for
the same period last year. For the first six months, R&D expenses totaled $86.6
million, compared to $43.6 million for the prior year period. The increase in
R&D expenses for the quarter were primarily driven by a $35.6 million write-off
of acquired in-process research and development costs arising from the
acquisition of the assets of Endeavor in November 2003. R&D costs for the
quarter also included a pre-tax charge of $2.2 million related to a write-down
of certain fixed assets in our Pomona, New York research center.

Proprietary Drug Research and Development

The Company currently has three applications for proprietary products pending at
the U.S. Food and Drug Administration (FDA): a supplemental New Drug Application
(sNDA) for Cenestin (Synthetic Conjugated Estrogens, A) 0.45 mg tablets, a New
Drug Application



[BARR LOGO]


(NDA) for Enjuvia(TM) (Synthetic Conjugated Estrogens) 0.3 mg and 0.45 mg
tablets and a NDA for Enjuvia (Synthetic Conjugated Estrogens) 0.625 mg and 1.25
mg tablets. In addition, the Company has six products in clinical development,
four of which are in Phase III studies.

Generic Drug Research and Development

The Company currently has 28 Abbreviated New Drug Applications (ANDAs) pending
at the FDA. During the quarter, the Company received five product approvals and
launched four products including generic versions of Organon, Inc.'s Remeron(R)
Soltab(TM) and Ortho-McNeil Pharmaceutical's Ortho Tri-Cyclen(R).

Patent Challenges

In October 2003, the Company announced the initiation of a patent challenge
related to Ortho-McNeil Pharmaceutical's Ortho Tri-Cyclen(R) Lo oral
contraceptive that is indicated for the prevention of pregnancy in women who
elect to use this product as a method of contraception.

In December 2003, the Company announced the initiation of a patent challenge for
King Pharmaceutical's Prefest(R) hormone therapy. Prefest is indicated in women
with an intact uterus for the treatment of moderate to severe menopausal
symptoms.

Selling, General and Administrative

SG&A expenses increased to $54.0 million for the quarter, compared to $33.1
million for the same period last year. For the first six months, SG&A expenses
totaled $119.5 million, compared to $64.4 million for the prior year period. The
increase in SG&A costs reflect the Company's continued and increasing commitment
to the sales and marketing of its expanding line of proprietary products
primarily related to higher sales force costs associated with the March 2003
expansion of the Company's Women's Healthcare Sales Force from 132 to 250 sales
representatives and launch costs for SEASONALE(R). The remainder of the increase
relates to higher costs associated with business development activities and
higher legal costs, and higher workforce costs to support the Company's growth.

Tax Rate

The Company's effective tax rate for the quarter decreased to 28.7%, as compared
to 37.3% in the prior year period. The tax rate for the quarter was favorably
impacted by a tax benefit of $3.9 million related to the completion of certain
state tax audits, and IRS approval of a change in the Company's method of
computing certain tax credits. The Company indicated that this change in method
is expected to slightly lower its effective tax rate in future periods.
Excluding the tax benefit, the Company's tax effective tax rate for the quarter
was 36.7%.

Balance Sheet

The Company's cash and marketable securities totaled $504.9 million at December
31, 2003. Cash flows from operations totaled $78.5 million for the quarter.
During the quarter, the Company used $35.6 million of cash to purchase the
assets of Endeavor and also funded capital investments of $7.4 million to
support the on-going growth of its business.

                 Use of Adjusted Non-GAAP Financial Information

To supplement its consolidated financial statements presented in accordance with
accounting principles generally accepted in the United States of America
("GAAP"), the Company is providing this summary to reflect the earnings per
share effect of the following items:

     o    the write-off of acquired in-process research and development
          associated with the purchase of certain assets and liabilities of
          Endeavor Pharmaceuticals, Inc. in November 2003, and

     o    the provision for losses on the Company's loans to Natural Biologics.

When disclosing financial information, Barr provides all information required in
accordance with GAAP, but believes that evaluating its results may be difficult
if limited to reviewing only GAAP financial measures. Barr's management does not
itself, nor does it suggest that investors should, consider such non-GAAP
financial measures in isolation from, or as a substitute for, financial
information prepared in accordance with GAAP. Barr presents such non-GAAP
financial measures in reporting its financial results to provide investors with
an additional tool to evaluate Barr's results. Barr's management believes it is
useful for itself and investors to review both GAAP information that includes
the charges mentioned above and the non-GAAP measure of earnings per share that
excludes such charges to have a better understanding of the overall performance
of Barr's business and its ability to perform in subsequent periods.
