and its components. Comprehensive income represents the change in net assets of
a business enterprise as a result of non-owner transactions. The adoption of the
standard did not have an impact on the Company's financial statements.

3. LOSS PER SHARE

         Since the Company incurred net losses in all periods presented,
outstanding options and warrants to purchase an aggregate of 1,018,737 and
1,399,755 shares of Common Stock at September 30, 1997 and 1998, 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 for
pain management. 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 for its most developmentally advanced drug, MorphiDex'TM'.
The Company may incur significant costs associated with the possible
commercialization of MorphiDex'TM' prior to the first commercial sale of the
product, including the purchase of inventory, the establishment of a sales
force, 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 September 30, 1997 and 1998

Research and development:

         In the three months ended September 30, 1998, research and development
expenses were $3.4 million, an increase of approximately $1.0 million or 43%,
from the comparable 1997 period. The significant increase in 1998 third quarter
expenses was primarily attributable to large-scale, advanced clinical trials of
MorphiDex'TM'. The Company also incurred higher expenses due to increased
development activity for HydrocoDex'TM' and the expansion of the Company's
development staff since the 1997 third quarter. The effect of these increases
was partially offset by reduced expenses in other development programs.

Selling, general and administrative:

         In the three months ended September 30, 1998, selling, general and
administrative expenses were $1.4 million, an increase of $0.8 million or 131%,
from the comparable 1997 period. The 1998 third quarter expense increase was
primarily attributable to general expansion of the Company's business, additions
to management personnel, market research and expenditures related to the
possible future commercialization of products such as the addition of sales and
marketing personnel and the move to the Company's new administrative offices.

Interest income:

         Interest income decreased 31% in the three months ended September 30,
1998 to $0.4 million due to lower average cash and securities balances compared
to the 1997 third quarter.


                                       7




Nine months ended September 30, 1997 and 1998

Research and development:

         In the nine months ended September 30, 1998, research and development
expenses were $10.4 million, an increase of approximately $2.9 million or 39%,
from the 1997 nine-month period. The significant increase in the nine-month 1998
expenses was primarily attributable to large-scale, advanced clinical trials for
MorphiDex'TM' and the expansion of the Company's development staff. The impact
of these increases was partially offset by reduced expenses related to
bioavailability studies and the costs of manufacturing small-scale regulatory
test batches of MorphiDex'TM', which occurred in 1997.

Selling, general and administrative:

         In the nine months ended September 30, 1998, selling, general and 
administrative expenses were $3.3 million, an increase of $1.4 million or 77%,
from the 1997 nine-month period. The nine-month results included approximately
$0.8 million of expenses for pre-marketing and related activities in preparation
for the commercialization of MorphiDex'TM'. The company incurred increased 
general and administrative costs to support the Company's business activities,
including the relocation and expansion of the Company's headquarters facilities
in April 1998.

Interest income:

         Interest income decreased 18% in the nine months ended September 30,
1998 to $1.5 million as a result of lower average cash and securities balances.

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 nine months ended September 30, 1998, cash outflows from operations amounted
to approximately $11.2 million compared to $6.3 million in the first nine months
of 1997, primarily as a result of its increased  MorphiDex'TM' development
spending.

         The Company intends to continue certain ongoing large-scale clinical
trials for MorphiDex'TM' and has entered into several research and development
commitments for HydrocoDex'TM'. The Company expects to incur continued product
development expenses as clinical trials of MorphiDex'TM' 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 its
research and development staff increased. In addition, in August 1998, the
Company filed a New Drug Application for its most developmentally advanced drug,
MorphiDex'TM'. The Company may incur significant costs associated with the
possible commercialization of MorphiDex'TM' prior to the first commercial sale
of the product, including the purchase of inventory, the establishment of a
sales force, preparation of promotional plans and materials, additions to and
changes in financial and operating systems, and other administrative expenses.
In November 1998, to provide greater financial flexibility the Company raised
$25 million in a private sale of common stock and warrants. The Company expects
that its cash and


                                       8




marketable securities 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.

         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; preparation of promotional plans and
materials and other activities in preparation for the possible commercialization
of MorphiDex'TM'; 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. If additional funds are required in the preparation for the possible
commercialization of MorphiDex'TM', 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.

Year 2000

         A potential problem exists for all companies that rely on computers as
the year 2000 approaches. Any of the Company's 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.

         The Company is in the process of evaluating the impact of the Year 2000
Issue and currently believes that the financial and operational systems of the
Company, as currently used, will function adequately with respect to the Year
2000 Issue given that the Company is not significantly reliant on its computer
software applications and systems during its developmental stage. In addition,
the Company has very limited information concerning the compliance status of 
its third party contractors. The Company's third party contractors generally 
test the Company's pharmaceuticals and provide the Company with its results. 
The Company 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'TM', the Company
intends to have third parties manufacture and distribute its products. The
Company 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 the Company as part of its preparation for the
commercialization of Morphidex'TM'. The Company has filed an NDA for
MorphiDex'TM' 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'TM'. If the Company
makes any such additions or changes, it would effect the Company's exposure to
the Year 2000 Issue since the Company would become more reliant on its computer
software applications and systems. Therefore, the Company's assessment of its
Year 2000 Issue is not complete and the Company cannot complete its assessment
or develop any contingency plans until mid-1999.


         At this time, the Company 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. The Company has not incurred significant
costs to date related to the Year 2000 Issue.
