                                   (Unaudited)



1. BASIS OF PRESENTATION

     The financial statements presented herein have been prepared in accordance
with generally accepted accounting principles for interim financial information
and with the instructions to Form 10-Q and Article 10 of Regulation S-X and are
unaudited. In the opinion of management, the financial statements reflect all
adjustments (which consist of normal recurring accruals and adjustments)
necessary for a fair statement of the financial position and results of the
interim periods presented.

2. LOSS PER SHARE

     Since the Company incurred net losses in all periods presented, outstanding
options and warrants to purchase an aggregate of 1,060,455 and 1,508,481 shares
of Common Stock at March 31, 1998 and 1999, respectively, were not included in
diluted per share calculations, as their effect would be antidilutive.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS.

General

     Algos, a development stage company, is engaged primarily in the development
and commercialization of proprietary pharmaceutical products. Since its
formation in January 1992, the Company has devoted a substantial amount of its
efforts to licensing technology, recruiting key management and staff, developing
products, filing patents and other regulatory applications and raising capital.

     The Company has incurred losses since its inception and expects to incur
losses in the future. The Company's product development expenses may increase as
additional drugs are developed. In August 1998, the Company filed a New Drug
Application (NDA) for its most developmentally advanced drug, MorphiDex'r'. The
Company may incur significant costs associated with the possible
commercialization of MorphiDex'r' prior to the first commercial sale of the
product, including the purchase of inventory, the establishment of a sales
force, the preparation of promotional plans and materials, additions to and
changes in financial and operating systems, and other related administrative
expenses.

Results of Operations

Three months ended March 31, 1998 and 1999

Research and development:

     In the three months ended March 31, 1999, research and development expenses
were $2.5 million, a decrease of approximately $700,000, or 22%, from 1998. In
1999, expenses decreased due to the impact in 1998 of large-scale, advanced
clinical trials and toxicology studies of MorphiDex'r' and the conduct of
formulation and manufacture of HydrocoDex'TM'clinical supplies. These effects
were offset by expenses related to Phase II clinical studies of HydrocoDex'TM'
in 1999.

Selling, general and administrative:

     In the three months ended March 31, 1999, selling, general and
administrative expenses were $3.5 million, an increase of $2.7 million from
1998. The significant increase was primarily attributable to the possible future
commercialization of products including fees to sales and marketing consultants,
educational materials and activities, and the addition of marketing personnel,
as well as the general expansion of the Company's business activities.

Liquidity and Capital Resources

     As a result of its drug development efforts, the Company has experienced
net cash outflows from operations since its inception in 1992. In the three
months ended March 31, 1999, cash outflows from operations amounted to
approximately $3.7 million compared to $3.0 million in the first quarter of
1998, primarily as a result of its increased expenses related to the possible
commercialization of MorphiDex'r'.

     The Company intends to continue certain pre-commercialization activities
and ongoing large-scale clinical trials for MorphiDex'r' in 1999 and has entered
into several research and development commitments for HydrocoDex'TM'. The
Company expects to incur product development expenses as clinical
trials of MorphiDex'r' continue and other drugs that the Company currently has
under development, including HydrocoDex'TM' move into advanced clinical trials
and as additional drugs are developed and research and development staff
increased. In August 1998, the Company filed an NDA for MorphiDex'r'. Algos may
incur significant costs associated with the possible commercialization of
MorphiDex'r' prior to the first commercial sale of

                                       5







the product, including the purchase of inventory, the establishment of a sales
force, the preparation of promotional plans and materials, additions to and
changes in financial and operating systems and other related administrative
expenses. The Company currently expects that its cash and marketable securities
at March 31, 1999 will be sufficient to fund its development activities for
approximately two years and provide for certain pre-launch activities based
upon the Company's current schedule of clinical trials and level of business
activities. However, if a significant portion of existing funds is required
in the preparation for the possible commercialization of MorphiDex'r', or if
additional trials are necessary or advisable, or if additional products are
developed, the Company may require additional funds. In the event that revenue
and income from successful product introductions or other internally generated
funds are insufficient for such efforts, the Company will need to raise
additional funds either by incurring debt, issuing additional equity or
through collaborative or license arrangements to ensure continuity of
operations. There is no assurance that the Company would be able to obtain
such additional financing on terms acceptable to the Company.

     The Company's future funding requirements will depend on a number of
factors, including: the amount of resources required for the establishment of
sales and distribution capabilities; the preparation of promotional plans and
materials and other activities in preparation for the possible commercialization
of MorphiDex'r'; the results of its development efforts; the timing and costs of
obtaining required regulatory approvals; the commercialization of competing
products; the execution of licensing or other collaborative research agreements
on terms acceptable to the Company; and the cost of prosecuting and defending
patents.

Year 2000

     A potential problem exists for all companies that rely on computers as the
year 2000 approaches. Any of Algos' computer software applications and systems
that use only the last two digits of a year to refer to a year may not properly
recognize the year 2000. This phenomenon (the Year 2000 Issue) could cause a
disruption of operations, including, among other things, a temporary inability
to engage in normal business activities.

     Algos is in the process of evaluating the impact of the Year 2000 Issue and
currently believes that the financial and operational systems of Algos, as
currently used, will function adequately with respect to the Year 2000 Issue
given that Algos is not significantly reliant on its computer software
applications and systems during its developmental stage. However, if certain
data management and statistical applications do not function properly, the
analysis and reporting of study results could be delayed and the timing of
subsequent development activities and regulatory filings adversely affected. In
addition, Algos has very limited information concerning the compliance status of
its third-party contractors. Algos' current third party contractors generally
test Algos products and provide Algos with the results of those tests. Algos
believes that any Year 2000 Issue for such third-party contractors would not be
material, since many activities could be performed without the aid of a
computer. As part of the commercialization of MorphiDex'r', Algos intends to
have third parties manufacture and distribute its products. Algos will place
significant dependence on the third parties' computer systems for purchasing,
production, customer order entry and invoicing and other related activities. A
disruption in these systems could result in lost revenue from inventory
shortages, improper execution of customer orders and/or delays in the resolution
and collection of outstanding invoices. Algos will evaluate each potential
third-party manufacturer's and distributor's readiness for the Year 2000 Issue
and will reevaluate the Year 2000 Issue as it relates to Algos as part of its
preparation for the commercialization of MorphiDex'r'. Algos has filed an NDA
for MorphiDex'r' and may make significant additions to and changes in its
existing computer software applications and systems and/or the use of such
systems in anticipation of the possible commercialization of MorphiDex'r'. If
Algos makes any such additions or changes, it would affect Algos' exposure to
the Year 2000 Issue since Algos would become more reliant on its computer
software applications and systems. Therefore, Algos' assessment of its Year 2000
Issue is not complete and Algos cannot complete its assessment or develop any
contingency plans until mid-1999.

                                       6








     At this time, Algos does not expect that the cost of its Year 2000 Issue
compliance program will be material to its business, financial condition or
results of operations and does not currently anticipate any material disruption
in its operations. Algos has not incurred more than $10,000 of costs to date
related to the Year 2000 Issue.
