         EXETER, NH, FEBRUARY 26, 2004 - Bentley Pharmaceuticals, Inc. (AMEX:
BNT), a technology-based specialty pharmaceutical and drug delivery company with
a growing branded and generic product line in Europe, today announced financial
results for the fourth quarter and twelve months ended December 31, 2003.

         Total revenues for the 2003 fourth quarter increased 57% (29% at
constant currency) to a record $18.1 million from $11.5 million in the
prior-year fourth quarter, reflecting the Company's expanding market share in
the European generic pharmaceuticals market and royalties from U.S. sales of
Auxilium's Testim(R), the first commercialized product containing Bentley's
CPE-215 technology. Fourth quarter operating income more than doubled to $2.6
million from $1.2 million in the comparable quarter of 2002. Net income in the
2003 fourth quarter increased 144% to $1.7 million, or $0.09 per basic common
share ($0.08 per diluted common share), compared to net income of $691,000, or
$0.04 per basic common share ($0.03 per diluted common share), in the 2002
fourth quarter.

         James R. Murphy, president and CEO, stated, "We had another outstanding
quarter fueled by continued growth of our branded and generic pharmaceutical
business in Europe. We are encouraged by the tremendous market opportunities in
Europe where we continue to build our presence as a leading, low-cost
manufacturer of high quality pharmaceutical products. We are equally encouraged
by the progress of our U.S. drug delivery business, which now has a consistent
and growing royalty stream from sales of Auxilium's Testim(R), the first
commercialized product containing our CPE-215 technology. In addition, we are
making significant progress with the developmental products in our
pipeline-most recently, we announced successful Phase I clinical trial results
for our proprietary intranasal insulin. We expect our Company to continue to
grow and mature throughout 2004."

         Total 2003 revenues grew by 65% (38% at constant currency) to a record
$64.7 million from $39.1 million in the prior year. Full-year income from
operations increased significantly to $11.4 million, an improvement of $7.4
million from last year. Net income for 2003 improved 273% to $6.1 million, or
$0.34 per basic common share ($0.28 per diluted common share), compared with
$1.6 million, or $0.10 per basic common share ($0.08 per diluted common share),
last year. Note that prior year net income included approximately $425,000 as a
result of an after-tax gain on the sale of a drug license.

         Michael D. Price, vice president and chief financial officer,
commented, "The strong rise in revenues in 2003 primarily reflects the continued
success of Bentley's branded and generic pharmaceutical products in Europe. Our
performance in Europe was mainly driven by sales of omeprazole and simvastatin,
and exports from Spain, which increased 227% in 2003 compared to 2002. The
October 2003 announcement of new price controls on certain pharmaceutical
products in Spain had a temporary effect on November product sales, as some of
our customers postponed purchases. Consequently, we made the decision to reduce
prices effective December 1, 2003, approximately one month ahead of schedule,
resulting in an increase in our market share. We are optimistic that careful
cost controls and increasing market share will enable us to improve our margins
in the future.

         Mr. Price added, "We also continued to strengthen our balance sheet
throughout 2003. Cash and short-term investment balances at December 31, 2003,
increased 51% to $40.6 million from $27.0 million last year, primarily due to
increased cash flow from operations and cash proceeds from the exercises of our
Class B Redeemable Warrants. Our current ratio is greater than 3 to 1 and we
have essentially no long-term debt."

         Working capital at December 31, 2003, increased 49% to $45.7 million
from $30.7 million at December 31, 2002. Total assets at December 31, 2003, grew
55% to $100.5 million from $64.7 at December 31, 2002, while stockholders'
equity increased 56% to $76.2 million at December 31, 2003 from $48.8 million at
December 31, 2002.

         Mr. Murphy concluded, "We are better positioned, both financially and
strategically, going into 2004 than at any time in our history. For the first
quarter of 2004, we expect to generate revenues in the range of $16 million to
$18 million. We anticipate another strong year in 2004, with total revenues in
the range of $70 million to $80 million. Our strong balance sheet will allow us
to continue to pursue opportunities to expand our business in the U.S. and
abroad. We continue to pursue our long-term strategy to penetrate high growth
markets, increase our pipeline and advance our drug delivery business. We look
forward to creating additional shareholder value in 2004."

COMPANY UPDATES

         o        In February 2003, Testim(TM), a patented testosterone
                  replacement therapy gel and the first product containing
                  Bentley Pharmaceuticals' patented CPE-215(TM) drug delivery
                  technology, was launched in the U.S. by its licensee, Auxilium
                  Pharmaceuticals, Inc. Since its launch, Auxilium's Testim(TM)
                  has continued to gain market share and clinical commendations
                  in the U.S., achieving approximately 10% of new prescriptions
                  by February 2004. Auxilium received its first European
                  approval in 2003 and recently entered into a distribution
                  agreement for the Canadian market place. Approximately 5
                  million men in the United States suffer from lower than normal
                  levels of testosterone.

         o        The Company's Spanish subsidiaries Laboratorios Belmac, S.A.,
                  Laboratorios Davur, S.L., and Laboratorios Rimafar, S.L. were
                  granted approvals by the Spanish Ministry of Health to market
                  several new drug formulations in Spain including paroxetine
                  and trimetazidine.

         o        The Company completed a successful Phase I clinical study
                  using its proprietary intranasal insulin product in human
                  volunteers. The study was conducted by a clinical research
                  organization in a hospital-based clinical pharmacology unit in
                  Ireland in compliance with U.S. and European clinical
                  standards. The clinical study consisted of 8 healthy
                  (non-diabetic) human volunteers who each received up to four
                  intranasal sprays of insulin over several weeks utilizing
                  Bentley's proprietary drug delivery technology. The Company is
                  planning additional studies for its intranasal insulin,
                  including the protocols for a Phase II study and an IND in the
                  U.S. The Company is also developing a licensing strategy.

                                      -4-


         o        In late February 2004, the Company's leading candidate to
                  license its topical Antifungal Nail Lacquer product line
                  decided not to move forward with a collaboration following a
                  change in their senior management. Bentley has opened
                  discussions with other potential licensees and continues to be
                  encouraged with the level of commercial interest in this
                  product line.

         o        The Company signed a wide-ranging agreement with Teva
                  Pharmaceutical Industries, Ltd in July 2000. A considerable
                  number of products resulting from this agreement are now in
                  the pipeline, and the Company expects these products to be an
                  important growth driver in 2004 and beyond.

         o        The Company signed an R&D agreement with Pfizer Inc in
                  December 2001. Following Pfizer's merger with Pharmacia,
                  progress on the collaboration has been slow. The current
                  agreement expires in April 2004.

         o        The Company has developed alliances in several European
                  countries, which have laid the groundwork for a significant
                  expansion into other high growth markets. As noted above,
                  exports from the Company's Spanish operations to other
                  European markets grew dramatically last year and this positive
                  trend is expected to continue.

         o        Almost all of the Company's outstanding Class B Redeemable
                  Warrants were exercised in 2003, generating more than $14
                  million in proceeds to the Company.

         o        In April 2003, the Company relocated its corporate
                  headquarters to Exeter, NH, where it opened a new research and
                  development laboratory focused on the advancement of it drug
                  delivery business in the U.S.

         o        Significant components of Bentley's revenues for 2003 and 2002
                  are summarized below:

         For the year ended December 31, 2002:
