Allergan Specialty Therapeutics, Inc.

Notes to Condensed Financial Statements

1.  Basis of Presentation and Significant Accounting Policies

    Allergan Specialty Therapeutics, Inc. ("ASTI" or "the Company") was
    incorporated in Delaware on November 12, 1997 and commenced operations on
    March 10, 1998. ASTI was formed for the purpose of conducting research and
    development of potential human pharmaceutical products, and to commercialize
    such products, most likely through licensing to Allergan, Inc. (Allergan).

    The Company is subject to risks associated with development stage companies.
    All of the Company's efforts to date have been limited to obtaining capital
    and board review of various research and development proposals presented by
    Allergan. The Company does not yet generate any revenues from product sales
    or royalties. Research and development is performed by Allergan and the
    costs incurred are reimbursed by ASTI.

    The accompanying financial statements at June 30, 1998 and for the quarter
    ended June 30, 1998 and for the period from commencement of operations to
    June 30, 1998 are unaudited, and in the opinion of management, includes all
    adjustments (consisting only of normal recurring accruals) necessary to
    present fairly the financial information contained therein. These statements
    do not include all disclosures required by generally accepted accounting
    principles. The results of operations for the period ended June 30, 1998 and
    for the period from commencement of operations to June 30, 1998 are not
    necessarily indicative of the results to be expected for the year ending
    December 31, 1998.

    Accounting for revenues and expenses

    ASTI's revenues consist solely of interest and investment income. In later
    years ASTI may also derive revenues from the sale or license of its
    products, most likely through the sale of licensed products by Allergan.
    Royalty and other product revenue will be recorded as earned.

    ASTI incurs most of its expenses under its agreements with Allergan.
    Research and development costs paid to Allergan under a Research and
    Development Agreement (R&D Agreement) are recorded as research and
    development expenses when incurred. Technology fees paid to Allergan under a
    Technology License Agreement (Technology Agreement) are recorded as
    technology fees on a straight-line basis over the life of the Technology
    Agreement. Amounts paid to Allergan under a Services Agreement are recorded
    as administrative expenses as incurred. See Note 2 for a description of the
    agreements between ASTI and Allergan.

    Use of estimates

    The preparation of financial statements in accordance with generally
    accepted accounting principles requires management to make estimates and
    assumptions that affect the amounts reported in the financial statements and
    accompanying notes. Actual results could differ from those estimates.

Notes to Condensed Financial Statements

1.  Basis of Presentation and Significant Accounting Policies (continued)

    The Company considers all highly liquid investments with an original
    maturity of three months or less to be cash equivalents. The Company invests
    its excess cash in money market funds, equity securities and debt
    instruments of financial institutions and corporations with strong credit
    ratings. The Company has established guidelines with respect to the
    diversification and maturities in order to maintain safety and liquidity. At
    June 30, 1998, all excess cash amounting to $179,894,000 was invested
    primarily in debt securities. ASTI classifies such investments as
    available-for-sale securities with net unrealized gains or losses as a
    component of other comprehensive income. Amounts classified as investments
    are liquidated and used to pay operating expenses as needed.

    Per share information

    In 1997, the Financial Accounting Standards Board issued Statement of
    Financial Accounting Standards (SFAS) No. 128, "Earnings per Share," (EPS).
    SFAS No. 128 requires calculations for "basic earnings per share" including
    only actual weighted shares outstanding and "diluted earnings per share"
    including the effect of any common equivalent shares or other items that are
    dilutive. The reconciliations of the numerators and denominators of the
    basic and diluted earnings per share computations for the quarter ended June
    30, 1998 and for the period from commencement of operations (March 10, 1998)
    to June 30, 1998 are as follows:

2.  Arrangements with Allergan, Inc.

    On March 10, 1998, 3,272,690 shares of callable Class A Common Stock of
    ASTI, representing all of the issued and outstanding shares of such class,
    were distributed by Allergan to the holders of record of Allergan common
    stock at the close of business on February 17, 1998 (the "Distribution").
    Prior to the Distribution, Allergan contributed $200,000,000 in cash to ASTI
    in exchange for all of the shares of ASTI Common Stock.

    On March 10, 1998, 1,000 shares of Class B Common Stock of ASTI,
    representing all of the issued and outstanding shares of such class,

2.  Arrangements with Allergan, Inc. (continued)

    were issued to Allergan. As sole holder of all of the issued and outstanding
    shares of Class B Common Stock, Allergan has the option to repurchase all of
    the outstanding Class A Common Stock under specified conditions.

    In connection with the Distribution, ASTI and Allergan entered into a number
    of agreements, including the R&D Agreement, Technology Agreement, Services
    Agreement and License Option Agreement (License Agreement).

    Pursuant to the R&D Agreement, ASTI reimbursed Allergan for research and
    development costs of $6,516,000 incurred during the quarter ended June 30,
    1998, with respect to the initial ASTI Products and Pre-Selection Work, as
    defined. Research and development expenses were $16,128,000 during the
    period from commencement of operations through June 30, 1998 which includes
    reimbursement to Allergan for research and development services performed
    during the period from October 24, 1997 through March 9, 1998. From time to
    time thereafter, Allergan shall propose work plans, subject to ASTI board
    approval, for the continued development of each of the initial ASTI Products
    as well as other product candidates. ASTI is required to utilize the cash
    initially contributed to ASTI by Allergan plus interest and investment
    income thereon, less administrative expenses and technology fees to conduct
    activities under the R&D Agreement. The R&D Agreement specifies payment of
    Developed Technology Royalties and Pre-Selection Product Payments by
    Allergan to ASTI under certain conditions. Through June 30, 1998, no amounts
    have been earned by ASTI with respect to Developed Technology Royalties or
    Pre-Selection Product Payments.

    Subject to certain limitations, the Technology Agreement grants ASTI an
    exclusive license to research and develop all of Allergan's proprietary and
    contractual rights with respect to certain retinoid and neuroprotective
    technologies. As consideration for the exclusive license, ASTI will pay a
    technology fee of $10,000,000 in year one; $6,700,000 in year two;
    $3,300,000 in year three; and $2,000,000 in year four commencing October 24,
    1997. The technology fee is charged to operations on a straight-line basis
    over the life of the Technology Agreement. The technology fee is payable
    monthly in arrears provided, however, that ASTI shall no longer be obligated
    to make such payments beginning with any month following the date on which
    the total number of ASTI Products either under development or licensed to
    Allergan pursuant to the License Agreement is less than two. Through June
    30, 1998, ASTI paid $6,855,000 in technology fees, of which $3,085,000 is
    included in prepaid technology fees in the accompanying balance sheet.

    ASTI has granted Allergan an option to acquire a license to each product
    developed under the R&D Agreement, including the Initial Products on a
    country-by-country basis at any time until (a) with respect to the United
    States, 30 days after clearance by the FDA to commercially market such ASTI
    Product and (b) with respect to any

    other country, 90 days after the earlier of (i) clearance by the appropriate
    regulatory agency to commercially market the product and (ii) clearance by
    the FDA to market the product in the United States.

    Upon exercise of the license option, Allergan will make Product Payments to
    ASTI as defined in the R&D Agreement. Through June 30, 1998, no license
    option has been exercised. The license option will expire to the extent not
    previously exercised, 30 days after the expiration of Allergan's option to
    purchase all of the outstanding ASTI Shares, described below.

    In accordance with ASTI's Restated Certificate of Incorporation, Allergan
    has the right to purchase all (but not less than all) of the ASTI Class A
    Common Stock (the "Purchase Option"). Allergan may exercise the Purchase
    Option by written notice to ASTI at any time during the period beginning
    immediately after the Distribution and ending on December 31, 2002; provided
    that such date will be extended for successive six month periods if, as of
    June 30, 2001, ASTI has not paid or accrued expenses for at least 95% of all
    Available Funds, as defined, pursuant to the R&D Agreement. In any event,
    the Purchase Option will expire 90 days after Allergan receives notice that
    the Available Funds (as defined in the R&D Agreement) held by ASTI is less
    than $15 million. Through June 30, 1998, Allergan has not exercised the
    Purchase Option.

    If the Purchase Option is exercised, the exercise price will be the greatest
    of:

    (a)(i) 25 times the aggregate of (1) all worldwide payments with respect to
    all Licensed Products, Developed Technology Products and Pre-Selection
    Products for the four calendar quarters immediately preceding the quarter in
    which the Purchase Option is exercised (Base Period) and (2) all payments
    that would have been made and all payments due to be made by Allergan to
    ASTI during the Base Period if Allergan had not previously exercised its
    payment buy-out option with respect to any product; provided, however, that,
    for the purposes of the foregoing calculation, for any product which has not
    been commercially sold during each of the four calendar quarters in the Base
    Period, Allergan will be deemed to have made Product Payments, Developed
    Technology Royalties and Pre-Selection Product Payments to ASTI for each
    such quarter equal to the average of the payments made during each of such
    calendar quarters during which such product was commercially sold, less (ii)
    any amounts previously paid to exercise any payment buy-out option for any
    product;

    (b)the fair market value of 500,000 shares of Allergan Common Stock
    determined as the average of the closing sales price of Allergan Common
    Stock on the New York Stock Exchange for the 20 trading days ending with the
    trading day that is two trading days prior to the date of determination.

    (c) $250 million less the aggregate amount of all technology fee payments
        and research and development costs paid or incurred by ASTI as of the
        date the Purchase Option is exercised; or

    (d) $60 million.

    In each case, the amount payable as the Purchase Option Exercise Price will
    be reduced to the extent, if any, that ASTI's liabilities at the time of
    exercise (other than liabilities under the R&D Agreement, Services Agreement
    and the Technology Agreement) exceed ASTI's cash and cash equivalents and
    short-term and long-term investments (excluding the amount of Available
    Funds remaining at such time). Allergan must pay the Purchase Option
    Exercise Price in cash.

    ASTI and Allergan have entered into a Services Agreement pursuant to which
    Allergan has agreed to provide ASTI with administrative services, including
    accounting and legal services on a fully-burdened cost reimbursement basis.
    The Services Agreement expires on December 31, 1998 and will be renewed
    automatically for successive one year periods during the term of the R&D
    Agreement. ASTI may terminate the Services Agreement at any time upon 60
    days written notice.

3.  New Accounting Standards

    In June 1997, SFAS No. 130, "Reporting Comprehensive Income," was issued.
    SFAS No. 130 established standards for reporting comprehensive income and
    its components. Other comprehensive income for the quarter ended June 30,
    1998 and for the period from commencement of operations through June 30,
    1998 is comprised of unrealized loss on investments of $144,000.

4.  Subsequent Events

    Subsequent to June 30, 1998, Allergan announced that it had entered into a
    multi-year research and development collaboration with Parke-Davis
    Pharmaceutical Research Division of Warner-Lambert Company to identify,
    develop and commercialize up to two RXR subtype selective retinoid compounds
    for the treatment of metabolic diseases, including adult onset diabetes,
    insulin resistant syndromes and dyslipidemias. RXR compounds have been
    accepted by ASTI as Pre-Selection Work. As a result, ASTI is entitled to
    receive a portion of the revenue stream paid by Warner-Lambert to Allergan.
    ASTI intends to use the funds received for further research and development.

    Subsequent to June 30, 1998, ASTI's Board of Directors approved a plan to
    fund Pre-Selection Work for androgen tears, which is being investigated for
    the treatment of dry eye, and certain research aimed at diseases of the
    retina.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS FOR THE QUARTER ENDED JUNE 30, 1998

This Quarterly Report on Form 10-Q may contain certain projections, estimates
and other forward-looking statements that involve a number of risks and
uncertainties. While this outlook represents management's current judgment on
the future direction of the business, such risks and uncertainties could cause
actual results to differ materially from any future performance suggested below.
The Company undertakes no obligation to release publicly the results of any
revisions to these forward-looking statements to reflect events or circumstances
arising after the date hereof.

The following should be read in conjunction with "--Risks and Uncertainties"
below and the Company's Financial Statements and notes thereto in Item 1 above.

RESULTS OF OPERATIONS
---------------------

Revenues, consisting of net interest and investment income earned on investment
funds, were $2,791,000 for the quarter ended June 30, 1998 and $3,508,000 for
the period from ASTI's commencement of operations, March 10, 1998, through June
30, 1998. Interest income was earned during the period from March 10, the date
Allergan contributed $200 million to ASTI, and June 30, 1998. In the future, as
ASTI's funds are used pursuant to the R&D Agreement and to pay the Technology
Fee pursuant to the Technology Agreement, lower cash balances will be available
for investment and therefore interest and investment income is expected to
decrease. During the period in which products are under development and
applications for regulatory clearance are submitted and reviewed, ASTI does not
anticipate revenues other than from interest and investment income.

Research and development expenses were $6,516,000 for the quarter ended June 30,
1998. Research and development expenses were $16,128,000 during the period from
commencement of operations through June 30, 1998 which includes reimbursement
for services performed during the period from October 24, 1997 through March 9,
1998. During the quarter, ASTI's Board of Directors approved work plans and cost
estimates presented by Allergan in accordance with the R&D Agreement for the
remainder of the 1998 calendar year. The approved work plans and cost estimates
are similar to the estimates provided in ASTI's prospectus dated March 6, 1998.

ASTI paid technology fees of $2,500,000 to Allergan during the quarter ended
June 30, 1998. ASTI paid technology fees of $6,855,000 for the period from
commencement of operations to June 30, 1998 which includes technology fees
incurred during the period from October 24, 1997 through March 9, 1998.

General and administrative expenses for the quarter ended June 30, 1998 and for
the period from commencement of operations through June 30, 1998 were not
material. It is anticipated that such expenses will increase in future reporting
periods, particularly with respect to expenses under the Services Agreement
pursuant to which Allergan has agreed to provide ASTI with administrative
services, including accounting and legal services, on a fully-burdened cost
reimbursement basis.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS FOR THE QUARTER ENDED JUNE 30, 1998

RESULTS OF OPERATIONS (Continued)
---------------------------------

In its early years, the results of operations of ASTI are expected to reflect
primarily interest and investment income on the funds contributed by Allergan,
and research and development expenses related to development of ASTI Products
and the Technology Fee. ASTI's net loss for the quarter ended June 30, 1998 was
$6,137,000 or $(1.87) per share. ASTI's net loss for the period from
commencement of operations through June 30, 1998 was $17,442,000 or $(5.33) per
share. ASTI is expected to continue to record significant net losses in future
periods, as expenses under its agreements with Allergan are expected to continue
to exceed investment income.

Provision for taxes was $922,000 for both periods presented. ASTI expects to
have taxable income as a result of the requirement to capitalize technology fees
and its likely election to capitalize research and development expenses for tax
purposes.

Under its agreements with Allergan, ASTI depends upon Allergan's operating and
accounting systems. Allergan has indicated to ASTI that Allergan's operating and
accounting systems applicable to ASTI are year 2000 compliant. ASTI does not
currently expect its financial condition or results of operations to be
materially adversely affected by year 2000 issues.

LIQUIDITY AND CAPITAL RESOURCES
-------------------------------

On March 9, 1998, Allergan contributed $200 million in cash to ASTI in exchange
for all of the issued and outstanding shares of callable Class A Common Stock of
ASTI. On March 10, 1998, Allergan distributed the Class A shares to holders of
Allergan common stock and ASTI commenced operations. The funds contributed by
Allergan, plus investment income earned thereon, will be used primarily to fund
the development of ASTI Products and to conduct related activities. Funds not
immediately required for development activities will be invested in low-risk
securities.

At June 30, 1998, ASTI had cash and cash equivalents of approximately $72,000.
The Company invests its excess cash in money market funds, equity securities and
debt instruments of financial institutions and corporations with strong credit
ratings. The Company has established guidelines with respect to the
diversification and maturities in order to maintain safety and liquidity. At
June 30, 1998, ASTI had $179,894,000 in investments. ASTI classifies such
investments as available-for-sale securities with net unrealized holding gains
or losses as a component of other comprehensive income. ASTI liquidates
investments to pay for operating expenses as needed.

Based on anticipated spending levels for the continued development of all the
current ASTI Products, it is expected that ASTI's funds for product development
will be exhausted during the next few years. At that time, product development
funding by ASTI will cease. However, several factors

Allergan Specialty Therapeutics, Inc.

OPERATIONS FOR THE QUARTER ENDED JUNE 30, 1998

LIQUIDITY AND CAPITAL RESOURCES (Continued)
-------------------------------------------

could impact the level and timing of ASTI funding, including the addition of any
new ASTI Products, the discontinuation of the development of any ASTI Products,
any commercial arrangements between Allergan and other companies which would
cause Allergan to exercise its License Option with respect to any ASTI Product,
any change in the number of projects advancing to or continuing in later stages
of development or any adjustments in the rate of spending on products currently
in development.

When ASTI's Available Funds (as defined in the R&D Agreement) is below $15
million, certain events will be triggered. First, Allergan's Purchase Option
with respect to all of the ASTI Class A Common Stock will terminate on the 90th
day after ASTI provides Allergan with a statement that, as of the end of any
calendar month, there are less than $15 million of Available Funds remaining.
Such statement will be accompanied by a report of ASTI's independent auditors.
In addition, Allergan has the right, for 30 days after expiration of the
Purchase Option, to license any or all ASTI Products which have not yet been
licensed, on a product-by-product and country-by-country basis. Allergan is
under no obligation to exercise the Purchase Option or the License Option with
respect to any ASTI Product. In the event that Allergan does not exercise the
Purchase Option or the License Option for all ASTI Products after ASTI's cash
available for product development is exhausted, ASTI will not have funds to
continue or complete development of any remaining products.

RISKS AND UNCERTAINTIES
-----------------------

New Company. ASTI is a newly formed company and is subject to the risks inherent
in the establishment of a new business enterprise in the biotechnology industry.
ASTI will incur substantial losses for several years due to the long-term nature
of the research and development of pharmaceutical products through clinical
testing and the regulatory process, which losses may never be recovered.

No Assurance of Continued Research or Development of ASTI Products. There can be
no assurance that the ASTI Board of Directors will continue the funding of the
research and development of the initial ASTI Products, or that any ASTI Products
can be successfully researched, developed and/or commercialized within the
anticipated cost estimates or time frames, if at all. Certain of the ASTI
Products are at critical stages of research and development, and technical and
clinical outcomes are impossible to predict. Because of the long-range nature of
any pharmaceutical product research and development plan, research and
development of a particular product or products could accelerate, slow down or
be discontinued, and other unforeseen events could occur, all of which would
significantly affect the timing and amount of ASTI's expenditures on a
particular product, or in total. As a result, estimates of costs and timing of
research and development programs and for the use of Available Funds may not be
accurate. There can be no assurance that Allergan will recommend, or that ASTI
will approve, additional products for research and development as ASTI Products
beyond the initial ASTI Products.

OPERATIONS FOR THE QUARTER ENDED JUNE 30, 1998 (Continued)

RISKS AND UNCERTAINTIES (Continued)
-----------------------------------

Although ASTI has received from Allergan a license to use Allergan Technology
for the purpose of researching, developing and commercializing ASTI Products,
some or all of the ASTI Products may require new technologies or enhancements or
modifications to existing Allergan Technology, and there can be no assurance
that such technology can or will be successfully developed or acquired. Even if
appropriate technology is available or developed, there can be no assurance that
such ASTI Products will be successfully researched or developed (or be
researched or developed in a timely fashion) or be proven to be safe and
efficacious in clinical trials.

Need for Regulatory Clearance. All ASTI Products, Developed Technology Products
and Pre-Selection Products will require FDA clearance before such products may
be lawfully marketed in the United States. Applications for FDA clearance must
be based on costly and extensive clinical trials designed to demonstrate safety
and efficacy. Clearance to market such products will also be required from
corresponding regulatory authorities in foreign countries before such products
may be marketed in those countries. Such clearance often involves pricing and
reimbursement approvals in addition to clearance based on safety and efficacy.
Delay in obtaining FDA and/or foreign regulatory clearance or pricing or
reimbursement approvals for any such product may have a material adverse effect
on the commercial success of such product. There can be no assurance that the
necessary regulatory clearances and approvals will be obtained in a timely
fashion or, if obtained, that such clearances and approvals will not be revoked
or withdrawn.

No Assurance of Sufficiency of Funds or Availability of Additional Funds.
Allergan has contributed $200 million in cash to ASTI. Allergan has no
obligation to contribute additional funds to ASTI, and has no present intention
to do so. It is anticipated that if ASTI were to fund the continued research and
development of the initial ASTI Products through FDA review for marketing
clearance, the funding of these activities, together with any Pre-Selection Work
undertaken by Allergan and/or ASTI and funded by ASTI, would require
substantially all of the Available Funds. There can be no assurance that ASTI
will have sufficient funds to complete the research and development of any or
all of the ASTI Products, including the four initial ASTI Products.

Allergan's rights under the Allergan/ASTI Agreements may limit ASTI's ability to
raise funds, or may prevent ASTI from doing so, if ASTI needs additional funds
to continue or complete research and development of any ASTI Product. If ASTI
were to attempt to raise funds following the expiration of the Purchase Option,
ASTI would have very little cash, few assets and an undeterminable number of
products under research and development. Allergan would at that time have the
unilateral option to license any or all ASTI Products for such countries for
which Allergan's License Option had not previously expired. Third parties might
therefore be reluctant to lend money to ASTI, or to invest in ASTI.

OPERATIONS FOR THE QUARTER ENDED JUNE 30, 1998 (Continued)

RISKS AND UNCERTAINTIES (Continued)
-----------------------------------

No Assurance of Successful Manufacturing or Marketing. Even if ASTI Products are
developed and receive necessary regulatory clearances and approvals, there can
be no assurance that the ASTI Products will be successfully manufactured for
clinical trials or successfully manufactured or marketed for commercial sale. To
be successfully marketed, any ASTI Product must be manufactured in commercial
quantities in compliance with regulatory requirements and at an acceptable cost.
Any significant delays in the completion of validation and licensing of expanded
or new facilities could have a material adverse effect on the ability to
continue clinical trials of and ultimately to market ASTI Products on a timely
and profitable basis. If Allergan does not exercise its License Option for an
ASTI Product (and does not exercise the Purchase Option), ASTI will have to make
alternative arrangements for manufacturing that ASTI Product, and there can be
no assurance that ASTI will be able to do so.

If Allergan exercises its License Option for any ASTI Product, Allergan may need
to develop and/or expand its marketing capabilities to commercialize such
Licensed Product effectively. If Allergan exercises its License Option for any
ASTI Product, and does not at the time the product is to be commercialized have
a sales force in the relevant country or countries, Allergan will need to
arrange for marketing by third parties outside of the United States, and, if the
product is not within Allergan's target markets at such time, within the United
States. If Allergan does not exercise its License Option for an ASTI Product
(and does not exercise the Purchase Option), ASTI will need to find other means
to commercialize that ASTI Product not involving Allergan, and there can be no
assurance that ASTI will be able to do so.

At the present time, ASTI does not have, nor, through the development stage of
the ASTI Products, does it expect to develop, any manufacturing or marketing
capability. If ASTI decides to manufacture or market one or more ASTI Products
itself, ASTI will need substantial additional funds. There is no assurance that
additional funds will be available, or will be available on attractive terms,
and Allergan has no obligation to supply any additional funds to ASTI. In
addition, ASTI may not use Available Funds for this purpose without Allergan's
consent.

If either Allergan or ASTI seeks a third party to manufacture or market an ASTI
Product, there can be no assurance that satisfactory arrangements can be
successfully negotiated or that any such arrangements will be on commercial
terms acceptable to Allergan or ASTI. In addition, even if ASTI decides to
license any ASTI Product to a third party, agreements with that third party, if
available, may be on terms less favorable to ASTI than the terms of the
Allergan/ASTI Agreements.

Even if acceptable manufacturing and marketing resources are available, there
can be no assurance that any ASTI Products will be accepted in the marketplace.
There can be no assurance that there will be adequate reimbursement by health
insurance companies or other third party payors for any ASTI Products that are
marketed.

RISKS AND UNCERTAINTIES (Continued)
-----------------------------------

No Assurance of Exercise of Allergan's Options. Allergan is not obligated to
exercise the License Option for any ASTI Product or to exercise the Purchase
Option, and Allergan will exercise any such option only if it is in Allergan's
best interest to do so. The timing of the exercise of the Purchase Option is
within Allergan's sole discretion, and Allergan may choose to exercise the
Purchase Option at a time when the Purchase Option Exercise Price is as low as
possible. Because the contractual relationship between Allergan and ASTI
contemplates that Allergan will perform research and development activities on
behalf of ASTI, in the event of Allergan's failure to exercise the Purchase
Option, ASTI would be required to seek alternative research and development
facilities, either independently or with a third party. There can be no
assurance that ASTI would be able to obtain access to adequate research and
development facilities in such event on a timely basis, on acceptable terms, or
at all. The timing of the exercise of the License Option with respect to any
Licensed Product is also within Allergan's sole discretion and thereafter
research, development and funding of any such product will be controlled by
Allergan.

Reliance on Proprietary Technologies; Unpredictability of Patent Protection.
Patent protection generally has been important in the pharmaceutical industry.
Therefore, ASTI's financial success may depend in part upon Allergan obtaining
strong patent protection for the technologies incorporated in ASTI Products.
Allergan will determine which patent applications to pursue, and the expense of
obtaining and maintaining patents covering Developed Technology will be shared
equally by Allergan and ASTI during the terms of the Research and Development
Agreement.

However, there can be no assurance that patents will be issued covering any
products, or that any existing patents or patents issued in the future will be
of commercial benefit. In addition, it is impossible to anticipate the breadth
or degree of protection that any such patents will afford, and there can be no
assurance that any such patents will not be successfully challenged in the
future. If Allergan is unsuccessful in obtaining or preserving patent
protection, or if any products rely on unpatented proprietary technology, there
can be no assurance that others will not commercialize products substantially
identical to such products.

Patents have been issued to third parties covering various therapeutic agents,
products and technologies. There can be no assurance that any ASTI Products,
Developed Technology Products or Pre-Selection Products will not infringe
patents held by third parties. In such event, licenses from such third parties
would be required, or their patents would have to be designed around. There can
be no assurance that such licenses would be available or that they would be
available on commercially attractive terms, or that any necessary redesign could
be successfully completed.

Allergan licenses certain intellectual property from third parties which it will
sublicense to ASTI pursuant to the Technology License Agreement. Specifically,
Allergan has licensed certain rights to its retinoid technology from Allergan
Ligand Retinoid Therapeutics, Inc. (ALRT) and certain rights to the technology
underlying Memantine from Children's Medical Center Corporation and Merz + Co.
GmbH & Co. ("Merz"). Under the terms of

RISKS AND UNCERTAINTIES (Continued)
-----------------------------------

certain of its license agreements, Allergan may be obligated to exercise
diligence and make certain royalty and milestone payments as well as incur costs
related to filing and prosecuting the underlying patents. Each agreement is
terminable by either party upon notice if the other party defaults in its
obligations. Should Allergan default under any of its agreements, Allergan and
therefore ASTI may lose its right to market and sell products based upon such
licensed technology. In addition, there can be no assurance that Allergan's
licensors will meet their obligations to Allergan pursuant to such licenses. In
such event, ASTI's results of operations and business prospects would be
materially and adversely affected.

Competition. ASTI Products, Developed Technology Products and Pre-Selection
Products are likely to face competition from other therapies for the same
indications. Competitors potentially include any of the world's pharmaceutical
and biotechnology companies. Many pharmaceutical companies have greater
financial resources, technical staffs and manufacturing and marketing
capabilities than Allergan or ASTI. A number of companies have developed and are
developing competing technologies and products. To the extent that ASTI
Products, Developed Technology Products and Pre-Selection Products incorporate
therapeutic agents that are off-patent or therapeutic agents marketed by
multiple companies, such products will face more competition than products
incorporating proprietary therapeutic agents.

The fundamental technology underlying retinoids licensed to ASTI is also
cross-licensed to Ligand Pharmaceuticals Incorporated (Ligand) and therefore
competition from similar activities by Ligand and its collaborators in retinoids
is likely. In addition, pursuant to an agreement between Allergan and Ligand,
each party has been granted non-exclusive rights to use any unsynthesized
compounds developed by ALRT provided that such license will become exclusive
with respect to any compound for which an IND is filed with and accepted by the
FDA. Accordingly, no assurance can be given that Ligand will not be the first
party to file an IND with respect to any retinoid compound under research by
ASTI, thereby preventing ASTI and Allergan from undertaking any further
research, development or commercialization with respect to such compound.

Potential Conflicts of Interest Between Allergan and ASTI. Because Allergan may
develop and/or market products (including Developed Technology Products and
Pre-Selection Products) for its own account, independent of ASTI, that compete
directly with ASTI Products, Allergan and ASTI may have conflicting interests
with respect to certain products and/or certain markets. In addition, ASTI
Products, Developed Technology Products and Pre-Selection Products may compete
with one another. Allergan Technology excludes, and ASTI will have no rights
with respect to, any topical formulation of Tazarotene. Allergan is currently
marketing a topical formulation of Tazarotene for the treatment of psoriasis and
acne in the United States under the brand name "Tazorac" and outside of the
United States under the brand name "Zorac".

RISKS AND UNCERTAINTIES (Continued)
-----------------------------------

Dependence on Allergan for Personnel and Facilities. ASTI will depend
substantially on Allergan for research and development activities to be
performed under the Research and Development Agreement. Although ASTI may
perform directly, or engage other third parties to perform on its behalf, some
of these activities, it is likely that Allergan will be responsible for
executing substantially all of ASTI's research and development activities. While
Allergan believes that its current and planned personnel and facilities will be
adequate for the performance of its duties under the R&D Agreement, such
personnel will perform services in the same facilities for Allergan itself.
Subject to Allergan's obligation to use diligent efforts under the R&D
Agreement, Allergan may allocate its personnel and facilities as it deems
appropriate. Allergan's own research and development activities may restrict the
resources that otherwise would be available for performing Allergan's duties
under the Research and Development Agreement.

Relationship Between ASTI and Allergan May Limit ASTI's Activities and Market
Value. The terms of the Allergan/ASTI Agreements and ASTI's Restated Certificate
of Incorporation were not determined on an arm's-length basis and certain terms
may limit ASTI's activities and its market value.

ASTI's Restated Certificate of Incorporation prohibits ASTI from taking or
permitting any action that might impair Allergan's rights under the Purchase
Option. Prior to the expiration of the Purchase Option, ASTI may not, without
the consent of the holders of ASTI Class B Common Stock, merge or liquidate, or
sell, lease, exchange, transfer or dispose of any substantial assets, or amend
its Restated Certificate of Incorporation to alter the Purchase Option, ASTI's
authorized capitalization, or the provisions of the Restated Certificate of
Incorporation governing ASTI's Board of Directors. Because Allergan owns all of
the outstanding Class B Common Stock, Allergan is able to influence
significantly or control the outcome of any of the foregoing actions requiring
approval by the Class B stockholders of ASTI. The ability of Allergan to
significantly influence or control such matters, together with the provisions of
ASTI's Restated Certificate of Incorporation eliminating the right of the ASTI
stockholders to call special meetings of stockholders, could affect the
liquidity of the ASTI Shares and have an adverse effect on the price of the ASTI
Shares, and may have the effect of delaying or preventing a change in control of
ASTI, including transactions in which stockholders might otherwise receive a
premium for their shares over the current market price. Neither the terms of the
ASTI/Allergan Agreements nor ASTI's Restated Certificate of Incorporation
prohibit Allergan from transferring its ASTI Class B Common Stock. The special
rights accorded to the holder or holders of the ASTI Class B Common Stock will
expire upon expiration of the Purchase Option.

So long as the Purchase Option is exercisable, the market value of the ASTI
Shares will be limited by the Purchase Option Exercise Price. The Purchase
Option Exercise Price was determined by Allergan, giving consideration to the
structure of the Distribution, ASTI's planned business, the Allergan/ASTI
Agreements, advice given by Merrill Lynch, Pierce, Fenner & Smith Incorporated,
and such other factors as Allergan deemed appropriate.

RISKS AND UNCERTAINTIES (Continued)
-----------------------------------

The Purchase Option Exercise Price was not determined on an arm's-length basis.

The existence of the Purchase Option and Allergan's rights as holder of the ASTI
Class B Common Stock may inhibit ASTI's ability to raise capital. Additional
capital raised by ASTI, if any, would most likely reduce the per share proceeds
available to holders of ASTI Shares if the Purchase Option were exercised. The
existence of the Purchase Option and Allergan's rights as the holder of the ASTI
Class B Common Stock may inhibit a change of control and may make an investment
in ASTI Shares less attractive to certain potential stockholders, which could
adversely affect the liquidity and market value of ASTI Shares.

If Allergan exercises its License Option for any ASTI Product, Allergan will
have the right to commercialize the product with third parties on such terms as
Allergan deems appropriate. In such event, payments from Allergan to ASTI with
respect to the ASTI Product will be based solely on Sublicensing Revenues
received from such third parties.

Limitation on ASTI's Ability to License Products to Third Parties. ASTI has
granted Allergan the License Option, which is exercisable on a
product-by-product and country-by-country basis. During the term of the License
Option for each ASTI Product, ASTI will not be able to license such ASTI Product
to any party other than Allergan. Furthermore, ASTI may perform research with
respect to product candidates which become ASTI Products only if recommended by
Allergan and accepted by ASTI. In particular, it is expected that Allergan will
perform Pre-Selection Work with respect to various product candidates. If such
product candidates do not become ASTI Products, ASTI will have no rights with
respect thereto except the right to receive limited royalties from Allergan on
commercial sales of such products, if any.

Possible Dilution; Reduction of Per Share Purchase Option Exercise Price. All
ASTI Shares issued by ASTI after the Distribution will be subject to the
Purchase Option, and the Purchase Option Exercise Price will not increase as a
result of any such issuance. Accordingly, if additional ASTI Shares were to be
issued, the percentage of the Purchase Option Exercise Price payable with
respect to each ASTI Share in the event Allergan exercises the Purchase Option
would be reduced. Liabilities, including any debt issued by ASTI, but excluding
any accounts payable to Allergan, will reduce the Purchase Option Exercise Price
to the extent that such liabilities exceed ASTI's cash, cash equivalents, and
short-term and long-term investments (excluding Available Funds), unless repaid
or discharged by ASTI prior to exercise of the Purchase Option.

No Dividends. ASTI's Restated Certificate of Incorporation prohibits the payment
of dividends from Available Funds.
