                    Endo Pharmaceuticals Achieves Strong
                           2001 Financial Results

 -- Results Reflect Strength of Product Line and New Strengths of Percocet(R)--
     -- 2001 Results Exceed Previous Guidance, 2002 Guidance Raised --

         CHADDS FORD, PA, February 20, 2002 -- Endo Pharmaceuticals
Holdings Inc. (Nasdaq: ENDP; ENDPW), a market leader in pain management,
today reported its financial results for the year and quarter ended
December 31, 2001.

         For the year ended December 31, 2001, Endo's net sales grew 28% to
$252.0 million from $197.4 million for the same period in 2000. Operating
loss decreased to $27.9 million from $147.9 million in the comparable 2000
period. Net loss decreased to $36.5 million from $156.8 million in the
comparable 2000 period. Consolidated EBITDA increased by 17% to $79.5
million from $67.7 million over the comparable 2000 period. Full year 2001
included a $23.0 million increase in selling, general and administrative
("SG&A") expense and a $13.0 million increase in research and development
("R&D") expense, primarily supporting new product marketing and new product
development.

         Carol A. Ammon, President and Chief Executive Officer of Endo
Pharmaceuticals, said, "We are extremely pleased with our 2001 financial
results. We continue to invest in research and development and sales and
marketing as well as the infrastructure to support our continued growth.
During the fourth quarter of 2001, we successfully launched our new
strengths of Percocet(R) and thus far are very satisfied with their market
acceptance. We also are excited that both Lidoderm(R) and our
extended-release morphine sulfate product continue to perform strongly and
gain market share.

         "Moreover, we have improved Endo's financial position. Having
successfully completed a public offering of an additional 12.9 million
shares of common stock in the fourth quarter of 2001, we used the proceeds,
for, among other things, the repayment of the Company's outstanding term
loans. We believe 2002 will be another year of growth for Endo. As a result
of the anticipated continued strength of our product line, we believe that
we are well positioned to achieve net sales in 2002 of approximately $280
million and consolidated EBITDA of $90 million. Of course, there can be no
assurance of Endo achieving these numbers."

         In addition, Endo announced that John W. Lyle has resigned as
Chairman and as a Director of the Company in order to be able to more
actively pursue other interests. Mr. Lyle will continue to support Endo's
marketing efforts pursuant to the agreement he entered into with the
Company in connection with the Company's acquisition of Algos
Pharmaceutical Corporation in July 2000. Ms. Ammon stated, "We thank John
for his service on our Board of Directors over the past year and a half,
and we look forward to his continued contributions to our company's
success."

         The Company also announced that the Board of Directors had
selected Carol A. Ammon to serve as Chairman of the Board, which will be in
addition to her current role as President and Chief Executive Officer of
the Company.

         For the fourth quarter ended December 31, 2001, Endo's net sales
increased to $78.5 million from $77.6 million for the same period in 2000.
As expected, the Company continued to experience generic erosion of its
Percocet(R) product during the fourth quarter of 2001. This erosion was
offset, in part, by the launch of its new strengths of Percocet(R). In
addition, net sales of Lidoderm(R) and other products increased during the
fourth quarter of 2001. Operating income increased 73% to $7.6 million from
$4.4 million. Net income increased to $8.0 million from a net loss of
($3.3) million in the comparable 2000 period. Earnings per share increased
to $.08 per diluted share for the fourth quarter of 2001 compared to a net
loss per diluted share of ($.04) in the comparable 2000 period.
Consolidated EBITDA decreased by 36% to $23.6 million from $37.1 million
over the comparable 2000 period. This decrease in consolidated EBITDA
occurred primarily due to an $8.8 million increase in SG&A expense and a
$3.6 million increase in R&D expense in 2001.

         During the fourth quarter of 2000, Endo recorded a $15.3 million
non-cash charge resulting from the vesting of stock options pursuant to the
Endo Pharma LLC stock option plans. Stock options granted pursuant to the
Endo Pharma LLC stock option plans vest if Endo's common stock reaches
certain defined thresholds. These options are exercisable for shares
currently held by Endo Pharma LLC, and their exercise will not dilute the
ownership of other holders of Endo common stock. Excluding this charge,
Endo would have recorded net income of $11.2 million or $.13 per share in
the fourth quarter of 2000.

         During the fourth quarter of 2001, Endo determined that the
utilization of its deferred tax benefits was more likely than not based on
its anticipated future taxable income in the foreseeable future.
Accordingly, Endo reversed its valuation reserves that had been recorded
against those deferred tax assets. The reversal of the reserves established
in connection with the acquisition of Algos Pharmaceutical Corporation
(Algos) in July 2000 were recorded as a reduction of goodwill. The reversal
of the reserves recorded subsequent to the Algos acquisition were recorded
as an increase to income tax benefit. In addition, during the fourth
quarter of 2001, the Company extinguished its term loan and recorded this
charge as an extraordinary item.

         Endo's results have fluctuated in the past, and may continue to
fluctuate. These fluctuations are primarily due to the timing of new
product launches, purchasing patterns of Endo's customers, market
acceptance of our products and the impact of competitive products and
pricing.


Forward-Looking Statements

         This press release contains forward-looking statements, within the

of competitive products and pricing; dependence on sole source suppliers;
the success of the Company's product development activities and the
timeliness with which regulatory authorizations and product launches may be
achieved; successful compliance with extensive, costly, complex and
evolving governmental regulations and restrictions; the availability on
commercially reasonable terms of raw materials and other third party
manufactured products; exposure to product liability and other lawsuits and
contingencies; dependence on third party suppliers, distributors and
collaboration partners; the ability to timely and cost effectively
integrate acquisitions; uncertainty associated with pre-clinical studies
and clinical trials and regulatory approval; uncertainty of market
acceptance of new products; the difficulty of predicting FDA approvals;
risks with respect to technology and product development; the effect of
competing products and prices; uncertainties regarding intellectual
property protection; uncertainties as to the outcome of litigation; changes
in operating results; impact of competitive products and pricing; product
development; changes in laws and regulations; customer demand; possible
future litigation; availability of future financing and reimbursement
policies of government and private health insurers and others; and other
risks and uncertainties detailed in Endo's Registration Statement on Form
S-4 filed with the Securities and Exchange Commission on June 9, 2000, as
amended, and in Endo's Registration Statement on Form S-3 dated October 17,
2001. Readers should evaluate any statement in light of these important
factors.

(1)      Definition of Consolidated EBITDA: Endo's credit facility defines
         Consolidated EBITDA as consolidated net income for the applicable
         period plus, without duplication and to the extent deducted from
         revenues in determining consolidated net income for that period,
         the sum of (a) the aggregate amount of consolidated cash interest
         expense for the period, (b) the aggregate amount of letter of
         credit fees paid during the period, (c) the aggregate amount of
         income tax expense for the period, (d) all amounts attributable to
         depreciation and amortization for the period, (e) all
         extraordinary and non-recurring charges during the period
         (provided that the amount of charges added to consolidated net
         income pursuant to this clause (e) that are incurred in connection
         with any transfer of manufacturing operations shall not exceed $10
         million during any fiscal year of Endo or $20 million in the
         aggregate) and (f) all other non-cash charges during the period;
         and minus, without duplication and to the extent added to revenues
         in determining consolidated net income for such period, the sum of
         (i) all extraordinary gains during the period and (ii) all other
         non-cash gains during such period, all as determined on a
         consolidated basis with respect to Endo and its subsidiaries in

Operating Income (Loss) to Consolidated EBITDA and Pro Forma Consolidated
EBITDA Reconciling Items:

Non-cash manufacturing charges reflect the present value of non-interest
bearing promissory notes issued annually to Bristol-Myers Squibb Pharma
Company ("BMS") (formerly the DuPont Pharmaceuticals Company) over the
initial five-year term of the manufacturing and supply agreement with BMS.
Compensation related to stock options is the non-cash charge resulting from
the vesting of stock options pursuant to the Endo Pharma LLC stock option
plans. Stock options granted pursuant to the Endo Pharma LLC stock option
plans vest if Endo's common stock reaches certain defined thresholds. These
options are exercisable for shares currently held by Endo Pharma LLC, and
their exercise will not dilute the ownership of other holders of Endo
common stock. Non-cash separation benefits is the non-cash charge resulting
from the acceleration of vesting of stock options held by two former
executives pursuant to two separation and release agreements entered into
by Endo in 2000. The assets acquired and liabilities assumed, results of
operations and cash flows of Algos have been included in Endo's financial
results prospectively for reporting periods beginning July 17, 2000. Pro
forma adjustments for Algos reflect results as if Algos was acquired on
January 1, 2000. Merger and other related costs are fees incurred in the
merger with Algos. Cash separation benefits is the cash charge related to
the severance recorded for two former executives.
