                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information and financial statements appearing elsewhere in this Prospectus.
Unless otherwise indicated, the information in this Prospectus assumes (i) the
Underwriters' over-allotment option will not be exercised and (ii) the
reincorporation of the Company in the State of Delaware. Investors should
carefully consider the information set forth under the heading "Risk Factors."
This Prospectus contains forward-looking statements that involve certain risks
and uncertainties. The Company's actual results may differ materially from the
results discussed in the forward-looking statements. Factors that might cause
such a difference include, but are not limited to, those discussed in "Risk
Factors" and elsewhere in this Prospectus.
 
                                  THE COMPANY
 
     Alanex Corporation ("Alanex" or the "Company") is a drug discovery company
that is applying its highly integrated and comprehensive approach to rapidly and
cost-effectively discover and optimize novel, small molecule drug candidates.
The Company's proprietary core drug discovery technology, Pharmacophore Directed
Parallel Synthesis ("PDPS"), accelerates the steps necessary to discover small
molecule drug candidates, from the initial identification of compounds that
exhibit activity against selected biological targets to the progression of these
compounds to drug candidates for human clinical trials. PDPS combines
combinatorial chemistry with computational and medicinal chemistries which, when
used in conjunction with high throughput screening and pharmacology, form an
integrated drug discovery platform that can be broadly applied to a wide array
of biological targets. An important element of the Company's strategy is to
enter into collaborations with pharmaceutical companies. Alanex has
collaboration agreements with Astra Pharma, Inc. ("Astra Pharma"), Novo Nordisk
A/S ("Novo Nordisk") and Roche Bioscience, a division of Syntex (U.S.A.) Inc., a
wholly owned subsidiary of Roche Holding Ltd. ("Roche Bioscience"). To date,
Alanex has used PDPS to identify one preclinical drug development candidate for
the treatment of pain and a number of lead compounds in four other programs that
address diseases or conditions for which existing therapies are inadequate or
unavailable, including diabetes, obesity, depression and anxiety.
 
     A major challenge for the pharmaceutical industry is the rapid and
cost-effective identification of lead compounds and their subsequent development
into drugs. Combinatorial chemistry -- which creates large libraries of
molecules by generating combinations of chemical building blocks -- represents a
significant advance in drug discovery technology, permitting the identification
of lead compounds on a more rapid and cost-effective basis. The Company believes
that a key factor in the successful application of combinatorial chemistry,
however, is the diversity, not simply the number, of compounds comprising a
combinatorial library. Alanex uses its proprietary library design software,
LiBrain, to maximize the diversity of its exploratory library by selecting for
synthesis compounds from Alanex's virtual library of over 140 million chemical
structures. The Company's exploratory library is increasing at an average rate
of 10,000 individual compounds per month and currently consists of over 150,000
synthesized compounds.
 
     Alanex believes that its ability to create a highly diverse library of
individual molecules increases the likelihood of discovering lead compounds. The
Company's drug discovery approach broadens the scope of combinatorial chemistry
to include the transition from lead compound to drug candidate by making
medicinal chemistry an integral part of the PDPS technology and by focusing on
the synthesis of compounds with drug-like structures. Optimization of lead
compounds into drug candidates can be accelerated by Alanex's ability to quickly
design and synthesize thousands of derivatives of a lead compound and purify
them using the Company's proprietary parallel chromatography technology.
 
     The Company's opiate agonist program, its most advanced drug discovery
program, has produced compounds that, in preclinical models, act as potent,
orally active analgesics with a novel mechanism of action for the treatment of
pain. This program is being conducted on behalf of Astra Pharma and is in
preclinical development. From initiation of this program to production of
preclinical compounds required only 14 months. Alanex's diabetes programs, which
are being pursued in conjunction with Novo Nordisk, focus on two distinct
molecular targets and have produced active lead compounds for each target.
Alanex's neuropeptide Y (NPY) antagonist program has produced active lead
compounds for the potential treatment of obesity and cardiovascular disease. In
addition, the Company's corticotrophin releasing factor (CRF) antagonist
 
                                        3
<PAGE>   5
 
program has produced active lead compounds that are being evaluated for the
treatment of depression and anxiety. Alanex recently initiated a project to
discover drugs that inhibit the action of gonadotropin releasing hormone (GnRH)
for the treatment of endometriosis and sex hormone-dependent tumors. Most
recently, in collaboration with Roche Bioscience, Alanex initiated a project to
discover an antagonist for an undisclosed target for the treatment for pain.
Alanex intends to continue to develop in-house programs for the discovery of new
drugs. The Company will also continue to seek corporate collaborations with
major pharmaceutical companies in order to capitalize on the emerging trend in
the pharmaceutical industry to outsource those components of drug discovery that
can be more efficiently provided by firms with unique or focused technologies.
 
     The Company commenced operations as Alanex, L.P., a California limited
partnership (the "Partnership"), in May 1991. In November 1993, the Partnership
was converted into a California corporation. The Company intends to
reincorporate in Delaware prior to the completion of this offering. The
Company's principal executive offices are located at 3550 General Atomics Court,
San Diego, California 92121, and its telephone number is (619) 455-3200.

                                  RISK FACTORS
 
     An investment in the shares being offered hereby involves a high degree of
risk. Prospective investors should carefully consider the following Risk
Factors, in addition to the other information contained in this Prospectus,
before purchasing the shares of Common Stock being offered hereby. This
Prospectus contains forward-looking statements that involve risks and
uncertainties. The Company's actual results may differ materially from the
results discussed in the forward-looking statements as a result of certain
factors, including those set forth in the following Risk Factors and elsewhere
in this Prospectus.
 
EARLY STAGE OF PRODUCT DEVELOPMENT; LACK OF COMMERCIAL PRODUCTS; NO ASSURANCE OF
SUCCESSFUL PRODUCT DEVELOPMENT
 
     The Company was founded in 1991 to discover novel small molecule
therapeutics for the treatment of diseases for which existing therapies are
inadequate or unavailable. To achieve profitable operations, the Company,
independently or in collaboration with others, must successfully identify,
develop and market proprietary products. The Company does not have any products
available for sale nor does it expect that any drug development candidates
identified by the Company will become commercially available as approved
pharmaceutical products for at least the next several years, if at all. The
Company's potential products are at very early stages of research and
development, with only one preclinical drug development candidate identified to
date. Under the terms of a collaboration agreement between the Company and Astra
Pharma, Astra Pharma owns all rights to compounds being developed for the
treatment of pain on behalf of Astra Pharma and the Company will not receive any
royalties on the sale of any products developed under the agreement.
 
     The Company's potential products will require significant additional
preclinical and clinical development, regulatory approval and additional
investment prior to commercialization, either by the Company independently or by
others through collaborative arrangements. Potential products that appear to be
promising at early stages of development may be ineffective or be shown to cause
harmful side effects during preclinical testing or clinical trials, fail to
receive necessary regulatory approvals, be difficult to manufacture, be
uneconomical to produce, fail to achieve market acceptance or be precluded from
commercialization by proprietary rights of others. There can be no assurance
that any potential products will be successfully developed, prove to be safe and
efficacious in clinical trials, meet applicable regulatory standards, be capable
of being produced in commercial quantities at acceptable costs or achieve
commercial acceptance.
 
NEW AND UNCERTAIN TECHNOLOGY AND BUSINESS
 
     The Company's integrated approach to drug discovery and its PDPS technology
are largely new approaches to drug discovery. There can be no assurance that the
Company will be able to employ its methods of drug discovery successfully or
that its technologies and methodologies will lead to the discovery or
development of commercial pharmaceutical products. Although the Company has
developed a number of potential lead compounds, to date, the Company has
developed only one preclinical drug development candidate. There can be no
assurance that any of the Company's product development efforts will be
successfully completed or that any product developed using the Company's
technology will achieve market acceptance. See "Business."
 
DEPENDENCE ON COLLABORATORS
 
     The Company's strategy involves the formation of collaboration agreements,
principally with pharmaceutical and biotechnology companies. The Company
currently has three such collaboration agreements. Historically, pharmaceutical
and biotechnology companies have conducted lead compound identification and
optimization within their own research departments due to the highly proprietary
nature of the activities, the central importance of these activities to their
drug discovery and development efforts and the desire to obtain maximum patent
and other proprietary protection on the results of their internal programs.
Pharmaceutical and biotechnology companies must be persuaded that the Company's
drug discovery technology and expertise justify entering into collaboration
agreements with the Company. There can be no assurance that the Company will be
able to negotiate additional collaboration agreements in the future on
acceptable terms, if at all, or that such current or future collaboration
agreements will be successful. To the extent that the Company
 
                                        6
<PAGE>   8
 
chooses not to or is unable to establish such agreements, it will require
substantially greater capital to undertake the research, development and
marketing of products at its own expense. In addition, in the absence of such
collaboration agreements, the Company may be required to delay or curtail its
research and development activities to a significant extent.
 
     The amount and timing of resources that current and future collaborators,
if any, devote to collaborations with the Company are not within the control of
the Company. There can be no assurance that such collaborators will perform
their obligations as expected or that the Company will derive any additional
revenue from such agreements. Moreover, the Company's collaborations may be
terminated by its collaborators upon three to six months' notice, which
terminations could result in the Company's relinquishing rights to products
developed jointly with its collaborators. In June 1996, the collaboration
agreement between the Company and Amgen Inc. ("Amgen") was terminated by Amgen.
In connection with the termination, the Company redeemed 2,978,182 shares of
Series A Preferred Stock held by Amgen by issuance to Amgen of an unsecured,
non-interest bearing promissory note in the principal amount of $4,500,000, due
June 28, 2001, and issued to Amgen a warrant to purchase 450,000 shares of
Common Stock of the Company at an exercise price of $1.51 per share. In
addition, pursuant to the termination agreement, Alanex is obligated to provide
to Amgen, on a non-exclusive basis, certain compounds that were included in the
Alanex technology licensed to Amgen under the collaboration agreement. In
exchange for such compounds, Amgen agreed to pay Alanex $400,000. Any future
termination of the Company's existing or future collaboration agreements could
have a material adverse effect on the Company's business, financial condition
and results of operations. See "Business -- Collaboration Agreements and
Licenses" and "Certain Transactions."
 
     The Company's agreements with its collaborators do not obligate the
collaborators to develop or commercialize lead compounds discovered by the
Company. Continued collaborator participation will depend not only on the
achievement of research objectives by the Company and its collaborators, which
cannot be assured, but also on each collaborator's own financial, competitive,
marketing and strategic considerations, all of which are outside the Company's
control. Such strategic considerations may include the relative advantages of
alternative products being marketed or developed by others, including relevant
patent and proprietary positions. There can be no assurance that the interests
and motivations of the Company's collaborators are, or will remain, aligned with
those of the Company, that current or future collaborators will not pursue
alternative technology in preference to that of the Company or that such
collaborators will successfully perform their development, regulatory
compliance, manufacturing or marketing functions. Should a collaborator fail to
develop or commercialize a compound or product to which it has rights from the
Company, the Company may not receive any future milestone payments or royalties
associated with such compound or product, and the Company may have only limited
or no rights to commercialize such compounds or products. In addition, there can
be no assurance any product will be developed and marketed as a result of such
collaborations or that any such development or commercialization would be
successful. See "Business -- Collaboration Agreements and Licenses" and
"Business -- Government Regulation."
 
HISTORY OF OPERATING LOSSES; UNCERTAINTY OF FUTURE OPERATING RESULTS
 
     The Company was initially formed as a partnership in May 1991 and was
incorporated in November 1993. Accordingly, the Company has only a limited
operating history upon which an evaluation of the Company and its prospects can
be based. As of June 30, 1996, the Company had an accumulated deficit of
$444,000. The Company incurred net losses for the years ended December 31, 1993,
1994 and 1995 of $981,000, $939,000 and $762,000, respectively. The Company
anticipates that its operating expenses will increase substantially in the
foreseeable future as it expands its operations. The increased expenses
associated with such expansion may not be offset by significant revenue.
Further, the Company's revenue from collaboration agreements is affected by the
timing of efforts expended by the Company and the timing of lead compound
identification. The Company's collaborative agreements provide for milestone
payments and/or royalties only upon significant preclinical and clinical
development, requisite regulatory approvals and successful marketing of
commercialized pharmaceutical products. The Company expects that its ability to
achieve profitability will be dependent upon the success of its current
collaborations as well as its ability to enter into additional collaboration
agreements. The Company has not yet received any significant revenue from the
achievement of milestones, royalties or license fees from the discovery,
development or sale of a commercial drug and, with regard to royalties and
license fees, no such revenue is expected for a number of years, if at all.

<PAGE>   9
 
FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FUNDING; RISK OF FURTHER
DILUTION TO STOCKHOLDERS
 
     To continue to maintain the competitiveness of its technologies and to
conduct costly and time-consuming research and development, the Company will be
required to raise substantial funds in addition to the proceeds from this
offering. The Company anticipates that the net proceeds from this offering,
together with the Company's existing capital resources, will be adequate to fund
the Company's operations through 1998. The Company's forecast of the period of
time through which its financial resources will be adequate to support its
operations is a forward-looking statement that involves risks and uncertainties,
and actual results could vary as a result of a number of factors, including
those described in these Risk Factors and elsewhere in this Prospectus.
 
     There can be no assurance that the Company's collaboration agreements will
produce revenue adequate to fund the Company's operating expenses. Moreover, the
Company's future capital requirements will depend on many factors, including,
among others, (i) continued scientific progress in its research and development
programs, (ii) the ability of the Company to establish and maintain
collaboration agreements, (iii) the costs involved in developing new
combinatorial chemistry and other capabilities, (iv) the costs involved in
preparing, filing, prosecuting, maintaining and enforcing patent claims, (v)
competing technological and market developments, (vi) progress of preclinical
and clinical trials and (vii) in the long term, effective commercialization
activities and arrangements.
 
     As of June 30, 1996, the Company had aggregate outstanding indebtedness of
approximately $6,507,000, consisting of an unsecured, non-interest bearing
promissory note in the principal amount of $4,500,000 (not discounted for
imputed interest) due June 28, 2001, $715,000 outstanding on its existing line
of credit and a term loan in the principal amount of $1,240,000 and $52,000 of
other indebtedness. The Company anticipates that it will need to raise
additional capital in order to conduct its operations and repay such
indebtedness. Such additional capital may be raised through additional public or
private financings, as well as collaboration agreements, borrowings and other
resources. To the extent that additional capital is raised through the sale of
equity or equity-related securities, the issuance of such securities could
result in dilution to the Company's stockholders. There can be no assurance that
additional funding will be available on favorable terms, if at all. If adequate
funds are not available, the Company may be required to curtail operations
significantly or to obtain funds through entering into arrangements with
collaborative partners or others that may require the Company to relinquish
rights to certain of its technologies or product candidates that the Company
would not otherwise relinquish. See "Use of Proceeds" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
MANAGEMENT OF MULTIPLE COLLABORATIONS
 
     The Company has three collaboration agreements and the Company's strategy
is to enter into additional collaboration agreements. Accordingly, because the
Company's agreements with its collaborators may result in the development of
similar compounds for multiple parties, there can be no assurance that conflicts
will not arise among collaborators as to rights to particular compounds in the
Company's libraries. Failure to successfully manage existing and future
collaborations, if any, or the occurrence of conflicts could have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Business -- Collaboration Agreements and Licenses."
 
GOVERNMENT REGULATION; NO ASSURANCE OF PRODUCT APPROVAL
 
     The U.S. Food and Drug Administration (the "FDA") and comparable agencies
in foreign countries impose substantial requirements on biotechnology and
pharmaceutical companies prior to the introduction of therapeutic products.
These requirements include lengthy and detailed laboratory and clinical testing
procedures, sampling activities and other costly and time-consuming procedures.
In particular, human therapeutic products are subject to rigorous preclinical
and clinical testing and other approval requirements by the FDA and comparable
foreign agencies. Although the time required for completing such testing and
obtaining such approvals is uncertain, satisfaction of these requirements
typically takes a number of years and varies substantially based on the type,
complexity and novelty of the pharmaceutical product. The Company cannot
accurately predict when product applications or submissions for FDA or other
regulatory review may
 
                                        8
<PAGE>   10
 
be submitted. The lengthy process of obtaining regulatory approvals and ensuring
compliance with appropriate federal statutes and regulations requires the
expenditure of substantial resources. Any delays or failure by the Company or
its collaborators or licensees to obtain regulatory approval and ensure
compliance with appropriate standards could adversely affect the
commercialization of such products, the Company's ability to earn product or
royalty revenue and its results of operations, liquidity and capital resources.
 
     Any future FDA or other governmental approval of products, developed by the
Company independently or by collaborators, may entail limitations on the
indicated uses for which such products may be marketed. Approved products may be
subject to additional testing and surveillance programs as required by
regulatory agencies. In addition, product approvals may be withdrawn or limited
for noncompliance with regulatory standards or the occurrence of unforeseen
problems following initial marketing. Any party that manufactures therapeutic
products, including collaborators or contract manufacturers, would be required
to adhere to applicable standards for manufacturing practices and to engage in
extensive record keeping and reporting. Any manufacturing facilities, whether of
the Company, its collaborators or contract manufacturers, would be subject to
periodic inspection by state and federal agencies, including the FDA and
comparable agencies in foreign countries. See "Business -- Government
Regulation."
 
     The effect of governmental regulation may be to delay the marketing of new
products for a considerable period of time, to impose costly requirements on the
activities of the Company or its collaborators or to provide a competitive
advantage to other companies that compete with the Company or its collaborators.
There can be no assurance that FDA or other regulatory approval for any products
developed by the Company or its collaborators will be granted on a timely basis,
if at all or, if granted, that compliance with regulatory standards will be
maintained. Adverse clinical results by the Company, its collaborators or by
others could have a negative impact on the regulatory process and timing. A
delay in obtaining, or failure to obtain, regulatory approvals could preclude or
adversely affect the marketing of products and the Company's liquidity and
capital resources. The extent of potentially adverse governmental regulation
that might arise from future legislation or administrative action cannot be
predicted.
 
     The Company is also subject to various federal, state and local laws,
regulations and recommendations relating to safe working conditions, laboratory
and manufacturing practices, the experimental use of animals and the use and
disposal of hazardous or potentially hazardous substances, including radioactive
compounds and infectious disease agents, used in connection with its research
work. The extent and character of governmental regulation that might result from
future legislation or administrative action cannot be accurately predicted. See
"-- Potential Liability Regarding Hazardous Materials."
 
INTENSE COMPETITION; RISK OF OBSOLESCENCE OF TECHNOLOGY
 
     Competition in the pharmaceutical and biotechnology industry is intense.
Many organizations are actively attempting to identify and optimize compounds
for potential pharmaceutical development. The Company competes directly with the
research departments of pharmaceutical companies, biotechnology companies,
chemical companies and with other combinatorial chemistry companies and research
and academic institutions. Many of these competitors have greater financial and
other resources, and more experience in research and development, than the
Company.
 
     Historically, pharmaceutical companies have maintained close control over
their research activities, including the synthesis, screening and optimization
of chemical compounds. Many of these companies, which represent potential
collaborators, are developing their own combinatorial chemistry and other
methodologies to improve productivity. Academic institutions, governmental
agencies and other research organizations are also conducting research in areas
in which the Company is working, either on their own or through collaborative
efforts. In addition, the Company competes with several alternative technologies
in the design and synthesis of new chemical libraries for drug discovery
programs. Such competition is based on the speed and efficiency of lead compound
identification and the efficiency of lead compound optimization. A competitor's
ability to identify or optimize lead compounds more quickly or more efficiently
than the Company could adversely affect the Company. The Company's processes may
be rendered obsolete or uneconomical by technological advances or entirely
different approaches developed by one or more of the
 
                                        9
<PAGE>   11
 
Company's competitors. There can be no assurance that the existing approaches of
the Company's competitors or new approaches or technology developed by the
Company's competitors will not be more effective than those of the Company. See
"Business -- Competition."
 
UNCERTAINTIES ASSOCIATED WITH PATENTS AND PROPRIETARY RIGHTS
 
     The Company's success will depend in large part on its ability, and the
ability of its licensees and licensors, to obtain patents for its technologies
and compounds, if any, resulting from the application of such technologies, to
defend patents once obtained and to maintain trade secrets, both in the United
States and in foreign countries. To date, the Company has filed six U.S. patent
applications. The success of the Company will also depend upon avoiding the
infringement of patents issued to competitors. There can be no assurance that
the Company or its collaborators will be able to obtain patent protection for
lead compounds or pharmaceutical products based upon the Company's technology.
Moreover, there can be no assurance that any patents issued to the Company or
its collaborators, or for which the Company has a license, will not be
challenged, invalidated or circumvented or that the rights granted thereunder
will provide competitive advantages to the Company. Litigation, which could
result in substantial cost to the Company, may be necessary to enforce the
Company's patent and license rights or to determine the scope and validity of
others' proprietary rights. If competitors of the Company prepare and file
patent applications in the United States that claim technology also claimed by
the Company, the Company may have to participate in interference proceedings
declared by the U.S. Patent and Trademark Office (the "PTO") to determine the
priority of invention, which could result in substantial cost to the Company,
even if the outcome is favorable to the Company.
 
     Because of the length of time and expense associated with bringing new
products through development and the length of time required for the
governmental approval process, the pharmaceutical industry has traditionally
placed considerable importance on obtaining and maintaining patent and trade
secret protection for significant new technologies, products and processes. The
Company and other biotechnology and pharmaceutical firms have applied, and are
applying, for patents for their products and certain aspects of their
technologies. The enforceability of patents issued to biotechnology and
pharmaceutical firms can be highly uncertain. Federal court decisions
establishing legal standards for determining the validity and scope of patents
in the field are in transition. For example, in a currently pending case, the
U.S. Supreme Court will consider whether to alter or replace the traditional
standard for determining patent infringement under the doctrine of equivalents.
There can be no assurance that the historical legal standards surrounding
questions of validity and scope will continue to be applied or that current
defenses as to issued patents in the field will offer protection in the future.
In addition, there can be no assurance that patents will issue or, if issued, as
to the degree and range of protection any such patents will afford or the extent
to which the Company will be successful in not infringing patents granted to
others.
 
     A number of pharmaceutical and biotechnology companies, and research and
academic institutions, have developed technologies, filed patent applications or
received patents on various technologies that may be related to the Company's
business. Some of these technologies, applications or patents may conflict with
the Company's technologies or patent applications. Such conflicts could also
limit the scope of the patents, if any, that the Company may be able to obtain
or result in the denial of the Company's patent applications.
 
     Many of the Company's competitors have, or are affiliated with companies
having, substantially greater resources than the Company, and such competitors
may be able to sustain the costs of complex patent litigation to a greater
degree and for longer periods of time than the Company. Uncertainties resulting
from the initiation and continuation of any patent or related litigation could
have a material adverse effect on the Company's ability to compete in the
marketplace pending resolution of the disputed matters. Moreover, an adverse
outcome could subject the Company to significant liabilities to third parties
and require the Company to license disputed rights from third parties or cease
using the technology. The Company is aware of a U.S. patent issued to a third
party that broadly claims proprietary rights in the automation of iterative
parallel synthesis technology. Although the Company believes that its current
activities do not infringe this patent, there can be no assurance that the
Company's belief would be affirmed in any litigation over the patent or that the
Company's future technological developments would be outside the scope of this
patent. In the event that
 
                                       10
<PAGE>   12
 
third parties have or obtain rights to intellectual property or technology used
or needed by the Company, there can be no assurance that any licenses would be
available to the Company or would be available on terms reasonably acceptable to
the Company.
 
     The Company also relies on certain proprietary technologies, trade secrets
and know-how that are not patentable. Although the Company has taken steps to
protect its unpatented trade secrets and technology, in part through the use of
confidentiality agreements with its employees, consultants and certain of its
contractors, there can be no assurance that (i) these agreements will not be
breached, (ii) the Company would have adequate remedies for any breach or (iii)
the Company's proprietary trade secrets and know-how will not otherwise become
known or be independently developed or discovered by competitors. See "Business
- -- Patents and Proprietary Information."
 
DEPENDENCE ON KEY EMPLOYEES
 
     The Company is highly dependent on the principal members of its scientific
and management staff. The Company does not maintain key person life insurance on
the life of any employee. The Company's future success also will depend in part
on the continued service of its key scientific personnel in its computational
and medicinal chemistry and pharmacology departments as well as software,
engineering and management personnel and its ability to identify, hire and
retain additional qualified personnel. The Company has entered into an
employment agreement with its Director of Finance. The Company has not entered
into employment agreements with any other key employees.
 
     There is intense competition for qualified personnel in the areas of the
Company's activities, and there can be no assurance that the Company will be
able to continue to attract and retain such personnel necessary for the
development of the Company's business. Because of the intense competition, there
can be no assurance that the Company will be successful in adding technical
personnel as needed to meet the staffing requirements of additional
collaborative relationships. Failure to attract and retain key personnel could
have a material adverse effect on the Company. See "Business -- Employees" and
"Management."
 
POTENTIAL LIABILITY REGARDING HAZARDOUS MATERIALS
 
     The research and development processes of the Company involve the
controlled use of hazardous materials. The Company is subject to federal, state
and local laws and regulations governing the use, manufacture, storage, handling
and disposal of such materials and certain waste products. The risk of
accidental contamination or injury from hazardous materials cannot be completely
eliminated. In the event of such an accident, the Company could be held liable
for any damages that result and any such liability could exceed the financial
resources of the Company. In addition, there can be no assurance that in the
future the Company will not be required to incur significant costs to comply
with environmental laws and regulations relating to hazardous materials. See
"Business -- Government Regulation."
 
RISK OF PRODUCT LIABILITY; POTENTIAL UNAVAILABILITY OF INSURANCE
 
     The Company's business will expose it to potential product liability risks
that are inherent in the testing, manufacturing and marketing of human
therapeutic products. The Company does not currently have product liability
insurance, and there can be no assurance that the Company will be able to obtain
or maintain such insurance on acceptable terms or, if obtained, that such
insurance will provide adequate coverage against potential liabilities.
 
CONCENTRATION OF OWNERSHIP
 
     Upon completion of this offering, the current directors, executive officers
and affiliated entities will beneficially own approximately 57.8% of the
outstanding Common Stock (54.5% of the outstanding Common Stock if the
over-allotment option is exercised in full). In particular, upon completion of
this offering, Debar ERA, Inc. ("Debar") and The Jon and Caroline Jessen Family
1990 Trust (the "Jessen Family Trust") will in the aggregate beneficially own
38.7% of the outstanding Common Stock (36.5% of the outstanding Common Stock if
the over-allotment option is exercised in full). Juli Jessen, the daughter of
Jon Jessen, a
 
                                       11
<PAGE>   13
 
director of the Company, is the trustee of the Jessen Family Trust. All of the
outstanding shares of Debar are held by the adult children of Jon Jessen and are
subject to a voting trust, the trustee of which is Mark Jessen, a son of Jon
Jessen. Mark Jessen, who is also the President and Chief Executive Officer of
Debar, has sole disposition and voting power over the shares held in the voting
trust. As a result, these stockholders will be able to exercise control over all
matters requiring stockholder approval, including the election of directors and
approval of significant corporate transactions. Such concentration of ownership
may also have the effect of delaying, discouraging or preventing tender offers
for the Common Stock or changes in control of the Company unless the terms are
approved by such stockholders. See "Principal Stockholders" and "Description of
Capital Stock."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     Sales of substantial numbers of shares of Common Stock in the public market
following this offering could adversely affect the market price for the Common
Stock. Upon completion of this offering, the Company will have outstanding
6,247,635 shares of Common Stock, based upon the number of shares outstanding as
of September 1, 1996. Of these shares, all of the 2,500,000 shares sold in this
offering will be freely tradable (unless such shares are purchased by
"affiliates" of the Company, as that term is defined in Rule 144 ("Rule 144")
under the Securities Act of 1933, as amended (the "Securities Act")), without
restriction or registration under the Securities Act. The remaining 3,747,635
shares of Common Stock held by existing stockholders are "restricted
securities," as that term is defined in Rule 144 under the Securities Act (the
"Restricted Shares"), and are eligible for public sale only if they are
registered under the Securities Act or sold in accordance with Rules 144, 144(k)
or 701 promulgated under the Securities Act ("Rule 701"). As a result of
contractual restrictions and the provisions of Rules 144, 144(k) and 701,
additional shares will be available for sale in the public market as follows:
(i) no Restricted Shares will be eligible for immediate sale in the public
market on the date of this Prospectus; (ii) 2,973,715 Restricted Shares (plus
522,182 shares of Common Stock issuable to employees pursuant to stock options
that are then vested) will be eligible for sale upon expiration of lock-up
agreements 180 days after the date of this Prospectus; and (iii) an additional
773,920 Restricted Shares will be eligible for sale from time to time thereafter
upon expiration of their respective two-year holding periods under Rule 144.
Future sales of shares by existing stockholders pursuant to Rule 144, 144(k) or
701 could have an adverse effect on the market price of the Common Stock or
otherwise impair the Company's ability to raise additional capital. See
"Description of Capital Stock" and "Shares Eligible for Future Sale."
 
ANTITAKEOVER PROVISIONS
 
     Certain provisions of the Company's Certificate of Incorporation and
Bylaws, as well as provisions of Delaware law, could discourage potential
acquisition proposals and delay or prevent a change in control of the Company.
For example, the Company's Certificate of Incorporation authorizes the Board of
Directors to issue up to 10,000,000 shares of Preferred Stock and to determine
the designations, price, rights, powers, preferences, privileges, and
limitations, including voting rights, of those shares without any further vote
or action by the stockholders. The rights of the holders of Common Stock will be
subject to, and may be adversely affected by, the rights of the holders of any
Preferred Stock that may be issued in the future. The Certificate of
Incorporation and Bylaws, among other things, provide for a classified Board of
Directors, require that stockholder actions occur at duly called meetings of the
stockholders, limit the persons who may call special meetings of stockholders,
do not permit cumulative voting in the election of directors and require advance
notice of stockholder proposals and director nominations. Certain provisions
contained in the Company's charter documents and certain applicable provisions
of Delaware law could discourage a hostile bid in which stockholders could
receive a premium for their shares. In addition, these provisions could have the
effect of making it more difficult for a third party to acquire a majority of
the outstanding voting stock of the Company, or delay, prevent or deter a
merger, acquisition or tender offer in which the Company's stockholders could
receive a premium for their shares, or a proxy contest for control of the
Company or other change in the Company's management. See "Management" and
"Description of Capital Stock."
 
NO PRIOR PUBLIC MARKET; POTENTIAL VOLATILITY OF STOCK PRICE
 
     Prior to this offering, there has been no public market for the Common
Stock and there can be no assurance that an active public market for the Common
Stock will develop or be sustained after this offering.
 
                                       12
<PAGE>   14
 
The initial public offering price will be determined by negotiation between the
Company and the Representatives of the Underwriters based on several factors and
may not be indicative of the book value of the Company's assets, market price of
the Common Stock after this offering or any other indicator of financial value.
See "Underwriting."
 
     In addition, the market prices for securities of biotechnology companies
have been highly volatile and the market has experienced significant price and
volume fluctuations that are unrelated to the operating performance of
particular companies. Announcements of failure to attain milestones with respect
to the Company's programs, the Company's ability or inability to enter into
additional collaborations, developments concerning proprietary rights, including
patents and litigation matters, publicity regarding actual or potential results
with respect to research or compounds under development by the Company or its
collaborative partners, regulatory developments in both the United States and
foreign countries, public concern as to the efficacy of new technologies,
developments in the field of combinatorial chemistry, general market conditions
and other factors may have a significant impact on the market price of the
Common Stock. Failures by other drug discovery companies, including
combinatorial chemistry companies, could have an adverse effect on the market
price of the Common Stock. In the past, following periods of volatility in the
market price for a company's securities, securities class action litigation has
often been instituted. Such litigation could result in substantial costs and a
diversion of management attention and resources, which could have a material
adverse effect on the Company's business, results of operations and financial
condition.
 
IMMEDIATE AND SUBSTANTIAL DILUTION; NO DIVIDENDS
 
     The initial public offering price of the Common Stock is substantially
higher than the net tangible book value per share of the Common Stock. At an
assumed initial public offering price of $11.00 per share, (the midpoint of the
range set forth on the cover page of this Prospectus) investors participating in
this offering will incur an immediate, substantial dilution in net tangible book
value of $6.79 per share and may incur additional dilution upon exercise of
outstanding stock options and warrants.
 
     The Company has never declared or paid any cash dividends on its capital
stock. The Company currently intends to retain any and all earnings for use in
its business and does not anticipate paying any dividends within the foreseeable
future. See "Dilution" and "Dividend Policy."

<PAGE>   15
 
                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the shares of Common Stock
offered hereby are estimated to be approximately $25,000,000 ($28,836,000 if the
Underwriters' over-allotment option is exercised in full), based on an assumed
public offering price of $11.00 per share (the midpoint of the range set forth
on the cover page of this Prospectus), and after deducting underwriting
discounts and commissions and estimated offering expenses.
 
     The Company currently intends to use the proceeds of this offering as
follows: approximately 65% for research and development, approximately 10% for
facilities expansion and approximately 25% for general corporate purposes and
working capital. The Company believes the net proceeds of this offering, along
with its existing resources, will be adequate to fund the Company's operations
through 1998. The preceding forward-looking statements are subject to certain
risks and uncertainties that could cause actual results to differ materially
from those projected, as set forth in Risk Factors and elsewhere in this
Prospectus. The amounts and timing of expenditures will depend, among other
things, on the rate of progress in expanding the Company's core technologies,
the Company's success in entering into collaboration agreements, the timing of
payments under the Company's current and future collaboration agreements, the
progress of ongoing research and development, the results of preclinical testing
and clinical trials, the rate at which operating losses are incurred, the FDA
regulatory process and other factors, many of which are beyond the Company's
control. The Company's management and Board of Directors have broad discretion
in determining how the proceeds of this offering will be allocated.
 
     In addition, the Company may use a portion of the net proceeds of this
offering to acquire or invest in complementary businesses or technologies,
through mergers, acquisitions, joint ventures or otherwise. However, the Company
currently has no specific agreements or commitments with respect to such
transactions.
 
     Pending the uses described above, the Company intends to invest the net
proceeds of this offering in short-term, investment grade securities.
 
                                DIVIDEND POLICY
 
     The Company has never declared or paid any cash dividends on its capital
stock. The Company currently intends to retain any future earnings to finance
the growth and development of its business and, therefore, does not anticipate
paying any cash dividends in the foreseeable future.

                                    DILUTION
 
     The net tangible book value of the Company as of June 30, 1996 was
approximately $1,282,000, or $0.34 per share. Net tangible book value per share
is equal to the Company's total tangible assets less total liabilities, divided
by the number of outstanding shares of Common Stock. After giving effect to the
sale by the Company of the 2,500,000 shares of Common Stock offered hereby (at
an assumed initial public offering price of $11.00 per share, the midpoint of
the range set forth on the cover page of this Prospectus) and after deducting
underwriting discounts and commissions and estimated offering expenses, the net
tangible book value of the Company at June 30, 1996 would have been
approximately $26,282,000 million, or $4.21 per share. This represents an
immediate increase in net tangible book value of $3.87 per share to existing
stockholders and an immediate dilution of $6.79 per share to new investors
purchasing shares in this offering. The following table illustrates this per
share dilution:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following Management's Discussion and Analysis of Financial Condition
and Results of Operations contains forward-looking statements that involve
certain risks and uncertainties. The Company's actual results may differ
materially from the results discussed in the forward-looking statements as a
result of certain factors, including those set forth under "Risk Factors" and
elsewhere in this Prospectus. The following discussion should be read in
conjunction with the Consolidated Financial Statements and the Notes thereto
included elsewhere in this Prospectus.
 
OVERVIEW
 
     The Company has devoted substantially all of its resources to the
development of its highly integrated and comprehensive drug discovery technology
and to its efforts to discover and optimize small molecule drug candidates. The
Company intends to continue to develop in-house programs for the discovery of
new drugs and has established and will continue to seek corporate collaborations
with major pharmaceutical companies and biotechnology companies. Since inception
in May 1991, the Company raised $6.3 million through private sales of equity
securities (including the sale to Amgen of 2,978,182 shares of Series A
Preferred Stock of the Company in April 1994). See "Certain Transactions."
 
     To date, the Company's revenue under collaboration agreements has consisted
of project initiation fees of $2.5 million and contract research revenue of $8.5
million. Contract research revenue is recognized at the time that research and
development activities are performed under the terms of the research contracts.
Contract research payments are generally received in advance of the performance
of the related research activities under the contract at the beginning of each
quarter. Such payments received in excess of amounts earned are recorded as
deferred contract research revenue. Project initiation fees and milestone
payments are nonrefundable and the contracts do not specify any future
performance obligations on the part of the Company related to such fees or
payments. Project initiation fees are recognized under the contract as revenue
when earned, generally when received, upon signing of an agreement. Revenue from
milestone payments will be recognized if and when the results or events
stipulated in the agreement have been achieved. To date, the Company has not
received any milestone payments under any of its collaboration agreements.
 
     The Company earned revenue in 1994 and 1995 under collaboration agreements
with Amgen, Astra Pharma and Novo Nordisk. The Company expects that it will
continue to earn revenue from the collaborations noted, with the exception of
the Amgen collaboration, which was terminated in June 1996. In addition, the
Company expects to earn revenue from a collaboration with Roche Bioscience. See
"Business -- Collaboration Agreements." The Company will be required to conduct
significant research and development activities over the next several years to
fulfill its obligations under its collaboration agreements. The Company has
incurred cumulative net losses of $444,000 through June 30, 1996.
 
     To date, the Company has not earned any revenue related to product sales
and the Company expects that its revenue sources over the next few years will be
limited to contract research payments under collaboration agreements. The timing
and amounts of such revenue will vary based on the terms of such collaboration
agreements. The Company anticipates that its operating expenses will increase
substantially as it expands its research and development efforts and the
increased expenses associated with such expansion may not be offset by
significant revenue.
 
RESULTS OF OPERATIONS
 
SIX MONTHS ENDED JUNE 30, 1996 AND 1995
 
     Total revenue for the six-month period ended June 30, 1996 increased by
164% to $4.2 million from $1.6 million in the six-month period ended June 30,
1995. Of the total revenue, contract research revenue in the six-month period
ended June 30, 1996 increased by 39% to $2.2 million compared to $1.6 million in
the corresponding period of 1995. For the six-month period ended June 30, 1996,
contract research revenue from the Company's collaborative agreements totalled
$1.3 million from Amgen, $386,000 from Astra and
 
                                       18
<PAGE>   20
 
$560,000 from Novo Nordisk. During the same period, project initiation fees were
$2.0 million, due to the signing of the Roche Bioscience collaboration
agreement.
 
     Research and development expenses for the first six months of 1996
increased by 49% to $2.3 million from $1.5 million in the same period of 1995.
The increase reflects increased research and development expenses incurred both
on behalf of collaborators and under programs funded by the Company.
 
     General and administrative expenses for the six-month period ended June 30,
1996 increased by 45% to $562,000 from $387,000 for the corresponding period of
1995. The increase is primarily due to increased legal expenses related to
contract negotiations and accounting expenses, expenses of recruiting and hiring
of administrative personnel and increased business development activities.
 
     The Company records and amortizes over the related vesting periods deferred
compensation representing the difference between the exercise price of options
granted and the deemed fair market value of its Common Stock at the time of
grant. Options generally vest over four years. Deferred compensation amortized
to expense through June 30, 1996 was $3,000. Amortization of deferred
compensation over the next four fiscal years in connection with options granted
to date, including compensation recognized to date, will aggregate $601,750 as
such options vest.
 
     The Company's net income for the six-month period ended June 30, 1996
compared to a net loss for the comparable period of 1995, is due principally to
the recognition of revenue from the non-refundable project initiation fee
received in connection with the signing of the three-year collaboration
agreement with Roche Bioscience in 1996.
 
YEARS ENDED DECEMBER 31, 1995, 1994, AND 1993.
 
     Total revenue increased by approximately 114% to $3.8 million in 1995 from
$1.8 million in 1994. This increase was due to a higher level of activity
related to collaborative research. Total revenue in 1993 was $29,000. For 1995,
contract research revenue from collaboration agreements totalled $2.6 million
from Amgen, $750,000 from Astra, $186,000 from Novo Nordisk and $8,000 from
miscellaneous research contracts, and a nonrefundable project initiation fee of
$250,000 from Novo Nordisk. The 1994 revenues were primarily attributable to
research support payments of $1.4 million from Amgen and a nonrefundable project
initiation fee of $250,000 from Astra Pharma.
 
     Research and development expenses increased by 69% to $3.7 million in 1995
from $2.2 million in 1994. Research and developments costs totaled $816,000 in
1993. The increases were due to increased levels of research and development
under collaboration agreements and programs funded by the Company and include
costs associated with hiring of research and development personnel, increased
costs associated with depreciation of equipment and facilities expenses and
increased purchases of laboratory supplies and services.
 
     General and administrative expenses increased by 37% to $804,000 in 1995
from $585,000 in 1994 primarily due to increased recruiting and hiring of
administrative personnel and expenses related to increases in travel for
business development, and legal and accounting expenses. General and
administrative expenses totaled $162,000 in 1993.
 
     The Company's net loss decreased by 19% to $762,000 in 1995 from $939,000
1994. The total net operating loss in 1993 was $981,000.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company has financed its operations since inception through the private
sales of equity securities, revenue from research collaborations and various
term financing arrangements. In 1994, the Company raised $4.5 million from the
private sale of Series A Preferred Stock in connection with a collaboration
agreement with Amgen. The Series A Preferred Stock was redeemed in June 1996 as
part of the termination of the collaboration agreement. In consideration of the
stock redemption, the Company issued to Amgen an unsecured, non-interest bearing
$4.5 million promissory note due on June 28, 2001. In connection with the
termination of the collaboration agreement, Amgen's warrant to purchase 703,636
shares of Common Stock was canceled and the Company issued to Amgen a new
warrant to purchase 450,000 shares of Common Stock at an exercise price of $1.51
per share with a term of seven years. See "Certain Transactions."
 
                                       19
<PAGE>   21
 
     In June 1994, the Company secured $1.2 million in working capital financing
from Merrill Lynch Business Financial Services, Inc. The credit facility
requires $240,000 of the principal balance of the loan to be converted to a term
loan and paid annually. Interest is due monthly at an interest rate of 2.95%
above the 30-day commercial paper rate (8.42% at September 12, 1996). The
repayment of the term note and all amounts outstanding on the credit facility
are secured by the assets of the Company and are also guaranteed by Amgen. At
June 30, 1996, $715,000 was outstanding under the line of credit.
 
     In May 1995, the Company acquired and improved new facilities at a total
cost of $1.9 million. Of this total, $1.4 million was financed by Genesee
Properties, the owner of the property, at 11% payable over a seven-year term.
 
     As of June 30, 1996, the Company had $4.3 million in cash, debt securities
available for sale and interest receivable. Through June 30, 1996, the Company
had invested $4.3 million in research facility improvements, laboratory and
computer equipment and furniture.
 
     Contract research payments under collaboration agreements are generally
received in advance of the performance of the related research activities at the
beginning of each quarter. Nonrefundable project initiation fees are generally
received upon the signing of the collaboration agreement. Under the Company's
collaboration agreements, milestone payments are to be received if and when the
results or events stipulated in the agreement have been achieved.
 
     The Company's net cash provided by operating activities was $2.6 million
for the six-month period ended June 30, 1996. The cash was provided primarily by
the revenue earned in June 1996 with the signing of the Roche Bioscience
collaboration agreement. Net cash provided by financing activities included $1.7
million of long-term financing in 1995 used for facilities expansion, $482,000
in 1994 and $124,000 in 1993. Net borrowings on the Company's line of credit
were $219,000 in 1995 and $506,000 in 1994. The Company's net cash used in
operating activities was $62,000 in 1995, $421,000 in 1994 and $834,000 in 1993.
Cash used for capital expenditures was $134,000 for the six-month period ended
June 30, 1996, $2.6 million in 1995, $1.3 million in 1994 and $3,000 in 1993.
The Company expects to use a portion of the proceeds of this offering for
additional capital expenditures. See "Use of Proceeds."
 
     The Company anticipates that the net proceeds from this offering, together
with its existing capital resources, will be sufficient to fund the Company's
operations and capital requirements through 1998. The Company's forecast of the
period of time through which its financial resources will be adequate to support
its operations is a forward-looking statement that involves risk and
uncertainties and actual results could vary as a result of a number of factors,
including those described herein and included in Risk Factors. There can be no
assurance the Company will not be required to use its available capital
resources sooner than anticipated. The Company's future capital requirements
will depend on many factors, including among others, (i) continued scientific
progress in its research and development programs, (ii) the ability of the
Company to establish and maintain collaboration agreements, (iii) the costs
involved in developing new combinatorial chemistry and other capabilities, (iv)
the costs involved in preparing, filing, prosecuting, maintaining and enforcing
patent claims, (v) competing technological and market developments, (vi)
progress of preclinical and clinical trials and (vii) in the long term,
effective commercialization activities and arrangements.
 
     The Company anticipates that it will need to raise additional capital over
the next several years in order to conduct its operations. Such capital may be
raised through additional public or private financings, as well as collaboration
agreements, borrowings and other available resources. To the extent that
additional capital is raised through the sale of equity or equity-related
securities, the issuance of such securities could result in dilution to the
Company's existing stockholders. There can be no assurance that additional
funding will be available on favorable terms, if at all.
 
NEW ACCOUNTING PRONOUNCEMENT
 
     In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards ("SFAS") No. 123, "Accounting for Stock-Based
Compensation," effective for fiscal years beginning after December 15, 1995.
Under the provisions of SFAS 123, the Company is encouraged, but not required,
to measure compensation costs related to its employee stock compensation under
the fair value method. If the Company elects not to recognize compensation
expense under this method, it is required to disclose the pro forma effects
based on the SFAS 123 methodology. The Company anticipates adopting the pro
forma method of disclosure under SFAS 123.

OVERVIEW
 
     Alanex is a drug discovery company that is applying its highly integrated
and comprehensive approach to rapidly and cost-effectively discover and optimize
novel, small molecule drug candidates. The Company's proprietary core drug
discovery technology, Pharmacophore Directed Parallel Synthesis (PDPS),
accelerates the steps necessary to discover small molecule drug candidates, from
the initial identification of compounds that exhibit activity against selected
biological targets to the progression of these compounds to drug candidates for
human clinical trials. PDPS combines combinatorial chemistry with computational
and medicinal chemistries which, when used in conjunction with high throughput
screening and pharmacology, form an integrated drug discovery platform that can
be broadly applied to a wide array of biological targets. An important element
of the Company's strategy is to enter into collaborations with pharmaceutical
companies. Alanex has collaboration agreements with Astra Pharma, Novo Nordisk
and Roche Bioscience. To date, Alanex has used PDPS to identify one preclinical
drug development candidate, which is for the treatment of pain, and a number of
lead compounds in four other programs that address diseases or conditions for
which existing therapies are inadequate or unavailable, including diabetes,
obesity, depression and anxiety.
 
     A major challenge for the pharmaceutical industry is the rapid and
cost-effective identification of lead compounds and their subsequent development
into drugs. Combinatorial chemistry -- which creates large libraries of
molecules by generating combinations of chemical building blocks -- represents a
significant advance in drug discovery technology, permitting the identification
of lead compounds on a more rapid and cost-effective basis. The Company believes
that a key factor in the successful application of combinatorial chemistry,
however, is the diversity, not simply the number, of compounds comprising a
combinatorial library. Alanex uses its proprietary library design software,
LiBrain, to maximize the diversity of its exploratory library by selecting for
synthesis compounds from Alanex's virtual library of over 140 million chemical
structures. The Company's exploratory library is increasing at an average rate
of 10,000 individual compounds per month and currently consists of over 150,000
synthesized compounds.
 
     Alanex believes that its ability to create a highly diverse library of
individual molecules increases the likelihood of discovering lead compounds. The
Company's drug discovery approach broadens the scope of combinatorial chemistry
to include the transition from lead compound to drug candidate by making
medicinal chemistry an integral part of the PDPS technology and by focusing on
the synthesis of compounds with drug-like structures. Optimization of lead
compounds into drug candidates can be accelerated by Alanex's ability to quickly
design and synthesize thousands of derivatives of a lead compound and purify
them using the Company's proprietary parallel chromatography technology.
 
     The Company's opiate agonist program, its most advanced drug discovery
program, has produced compounds that, in preclinical models, act as potent,
orally active analgesics with a novel mechanism of action for the treatment of
pain. This program is being conducted on behalf of Astra Pharma and is in
preclinical development. From initiation of this program to production of
preclinical compounds required only 14 months. Alanex's diabetes programs, which
are being pursued in conjunction with Novo Nordisk, focus on two distinct
molecular targets and have produced active lead compounds for each target.
Alanex's neuropeptide Y (NPY) antagonist program has produced active lead
compounds for the potential treatment of obesity and cardiovascular disease. In
addition, the Company's corticotrophin releasing factor (CRF) antagonist program
has produced active lead compounds that are being evaluated for the treatment of
depression and anxiety. Alanex recently initiated a project to discover drugs
that inhibit the action of gonadotropin releasing hormone (GnRH) for the
treatment of endometriosis and sex hormone-dependent tumors. Most recently, in
collaboration with Roche Bioscience, Alanex initiated a project to discover an
antagonist for an undisclosed target for the treatment for pain. Alanex intends
to continue to develop in-house programs for the discovery of new drugs. The
Company will also continue to seek corporate collaborations with major
pharmaceutical companies in order to capitalize on the emerging trend in the
pharmaceutical industry to outsource those components of drug discovery that can
be more efficiently provided by firms with unique or focused technologies.

BACKGROUND
 
     The discovery process for small molecule drugs typically includes two
steps: lead discovery and optimization of leads into drug candidates. Lead
discovery is the identification of one or more compounds that are active with
respect to a selected biological target. These compounds are identified through
screening of large collections of chemical compounds, either accumulated over
time or newly synthesized using combinatorial chemistry. A compound with the
most desirable pharmacological features is selected as a lead compound.
 
     Although lead compounds display desirable pharmacological characteristics,
they typically do not initially have sufficient potency and selectivity to
qualify as drug candidates. Lead optimization improves upon a lead compound's
pharmacological characteristics by synthesizing and testing a number of
structural analogs of the lead compound. Typically, the chemical structure of
the lead compound must be significantly modified to optimize bioavailability and
stability and to minimize toxicity and undesirable side effects.
 
  TRADITIONAL DRUG DISCOVERY
 
     Historically, lead discovery and optimization were performed almost
exclusively by the internal research and development departments of large
pharmaceutical companies. In general, pharmaceutical companies' drug discovery
programs were limited to the use of collections of natural products and
compounds developed in previous drug discovery programs. As a result, existing
pharmaceutical libraries typically reflect a lack of chemical diversity and
breadth. Once lead compounds were identified, optimization was performed one
compound at a time using traditional medicinal chemistry. This approach to lead
discovery and optimization has been time consuming, expensive and often
ineffective in yielding a successful drug candidate.
 
     Recently, the pharmaceutical industry has been under pressure to lower the
cost and increase the efficiency of its drug discovery efforts. Cost containment
efforts by governmental agencies, managed care organizations and third-party
payors have reduced profit margins, particularly for drugs that have generic
equivalents or therapeutic alternatives. To overcome pricing pressures,
pharmaceutical companies must develop innovative drugs that address unmet
medical needs or offer improvements over available therapies. At the same time,
advances in molecular biology and genomics have led to the discovery of an
increasing number of novel biological targets. Research efforts at
pharmaceutical and biotechnology companies, universities and other institutions
have identified novel receptors, enzymes and other proteins as drug targets and
have generated information on their potential role in human diseases. The
identification of these targets has expanded the opportunity for the discovery
and development of new drugs.
 
     Despite the proliferation of new drug targets and increased spending on
drug discovery by major pharmaceutical companies, there has not been a
significant increase in the number of new drugs approved by the FDA on an annual
basis over the last 12 years. Furthermore, the time required to develop and
commercialize a drug is, on average, 15 years. Consequently, pharmaceutical
companies have placed high priority on improving their drug discovery
productivity and on capitalizing in an efficient manner on the proliferation of
new molecular targets.
 
  COMBINATORIAL CHEMISTRY
 
     Combinatorial chemistry emerged as a solution to many of the challenges of
traditional drug discovery. Combinatorial chemistry methods are capable of
generating large libraries of diverse molecules by creating combinations of
chemical building blocks. Such methods are intended to significantly shorten the
time and reduce the costs traditionally associated with the drug discovery
process.
 
     Initial combinatorial chemistry methods were based primarily on the use of
oligomeric chemistry in which a single chemical reaction was used to combine
structurally different building blocks in a polymeric fashion. However,
compounds in libraries compiled using oligomeric chemistry methods, typically
oligonucleotides and peptides, are generally not ideal drug candidates because
they are not usually bioavailable and are metabolized quickly.
 
     A significant advance in combinatorial chemistry was the shift to the
synthesis of drug-like, small molecule compounds that would be orally
bioavailable and metabolized at an acceptable rate. However, these
 
                                       22
<PAGE>   24
 
compounds were typically generated in large mixtures. The use of mixtures makes
it possible to synthesize many compounds simultaneously and to screen them as
mixtures. The large number of compounds present in mixtures, however, requires
elaborate tagging and deconvolution methods to identify the specific compounds
with activity. These methods are generally expensive and time consuming.
Moreover, biological testing of mixtures often generates false positive results,
which can lead to inefficient and unproductive research.
 
     The Company believes that existing combinatorial chemistry technologies
lack robust methods for converting active compounds identified through the
screening of libraries into lead compounds and drug candidates. Screening of
combinatorial libraries usually results in the identification of one or more
active compounds, or "hits." These hits may represent false leads or may be
weakly active predecessors of highly active and desirable drug candidates. Thus,
library screening and hit identification represent only the first in a series of
steps required for successful drug discovery. Combinatorial chemistry must be
integrated with medicinal chemistry and pharmacology to perform not only initial
improvement of activity of identified hits, but also full optimization of other
pharmacological characteristics, such as selectivity, metabolic stability,
bioavailability and safety.
 
     The Company believes that the successful application of combinatorial
chemistry will require an integrated comprehensive approach to drug discovery
that will:
 
     - Produce distinct individual compounds in sufficient numbers to generate
       active hits against specific biological targets while avoiding the
       limitations associated with the testing of mixtures;
 
     - Generate diverse libraries containing only drug-like small molecules with
       a relatively greater likelihood of being developed into drug candidates;
       and
 
     - Efficiently develop hits identified through the screening of compound
       libraries into lead compounds and drug candidates by integrating
       medicinal chemistry and pharmacology.
 
ALANEX'S DRUG DISCOVERY TECHNOLOGY
 
  OVERVIEW
 
     Alanex's drug discovery process is built around its PDPS technology that
has been designed to produce large numbers of diverse individual small molecule
compounds. PDPS is instrumental not only in the initial identification of active
lead compounds, but also in the efficient optimization of these leads into a
drug candidate. This is achieved by integrating combinatorial, computational and
medicinal chemistries with high throughput screening and
pharmacology -- disciplines that the Company believes are critical for achieving
success in drug discovery.

     Drug discovery at Alanex relies on the generation and screening of
combinatorial libraries. The successful discovery of drug candidates requires
that libraries be intelligently designed to provide a desired range of molecular
diversity and to incorporate available structural information about the selected
biological target. Alanex's proprietary library design software, LiBrain, is
used to create a large "virtual" library from which compounds to be synthesized
are selected, thereby facilitating the design of diverse exploratory, targeted
or analog combinatorial libraries. If no information is available regarding the
requirements for drug activity for a selected target, the initial search for a
hit is performed by screening Alanex's exploratory library, which consists of a
large number of molecules that have been selected to maximize diversity. When
information is available regarding the requirements for drug activity, targeted
or focused libraries are synthesized and screened. In a step-by-step fashion,
increasingly focused libraries are synthesized and screened to yield a drug
candidate with desirable activity. Alanex's PDPS technology produces
combinatorial libraries through high-speed, parallel synthesis of arrays of low
molecular weight individual compounds in a standard 96-well format used in high
throughput screening. Synthesized compounds can be purified using Alanex's
proprietary parallel chromatography technology.

<PAGE>   26
 
  COMBINATORIAL LIBRARIES
 
     Virtual Library. Alanex has created and is continuing to expand its virtual
library -- a collection of chemical structures that result from the combination
of available reagents with the chemical reactions for library synthesis.
Although the Company's proprietary software can access tens of billions of
molecular structures, the virtual library includes only those structures that
are drug-like and can be synthesized at Alanex within one or two days.
Currently, the Company's virtual library contains over 140 million such
structures, and its size increases as more reactions and more available building
blocks are added. This resource provides Alanex the ability to rapidly create
exploratory, targeted and analog libraries to use in the drug discovery process.
 
     Exploratory Library. Alanex's exploratory library contains a diverse set of
molecules. Compounds in the Company's exploratory library are screened when no
information is available about the structure of the target or about small
molecules that are capable of binding to the target. As of July 1996, Alanex's
exploratory library contained over 150,000 synthesized compounds. The library
continues to grow at an average rate of approximately 10,000 individual
compounds per month.
 
     Targeted Pharmacophore-Directed Libraries. Alanex's targeted libraries are
designed to incorporate all available information about the structural
requirements of a target. Alanex utilizes its targeted libraries either to
perform combinatorial optimization directed at identified hits or to discover
novel leads that are structurally different from known molecules but display
similar pharmacophoric features. A typical Alanex targeted library contains
between several hundred and several thousand compounds.
 
     Analog Libraries. Once an active compound has been identified, related
structural analogs are synthesized to determine which parts of the molecule are
critical for biological activity and which parts can be replaced or modified to
optimize other pharmacological characteristics, such as oral bioavailability.
This task, traditionally performed by medicinal chemists one analog at a time,
is accomplished at Alanex using PDPS to rapidly design and synthesize analog
libraries typically containing between several dozen and several hundred
analogs.
 
  IDENTIFICATION OF LEAD COMPOUNDS
 
     To screen the large numbers of compounds generated through the application
of Alanex's PDPS technology, the Company has established high throughput
screening facilities currently capable of testing thousands of compounds per
day. All screening operations are performed in a standard 96-well format using
commercially available robotic workstations, which allow systematic expansion of
capacity as needed. A dedicated group of pharmacologists develops and supports
new high throughput screening assays. When hits are identified using new high
throughput screening assays, they are subjected to a series of secondary
pharmacological assays to determine their functional activity and selectivity.
Confirmed hits displaying promising pharmacological profiles become chemical
leads.
 
  OPTIMIZATION OF LEAD COMPOUNDS INTO DRUG CANDIDATES
 
     Lead compounds usually require significant structural modification to
optimize their activity, selectivity and bioavailability, or to improve
metabolic stability and minimize toxicity. Lead optimization is an iterative
process in which structural and biological information obtained from each series
of active molecules is used to design and synthesize new compounds with improved
pharmacological characteristics. Alanex has incorporated its medicinal chemistry
expertise into PDPS to significantly accelerate the optimization of lead
compounds into viable drug candidates. New targeted and analog libraries focused
on essential structural and pharmacological features of current leads are
rapidly designed and synthesized. Compounds in these libraries are purified
using Alanex's parallel chromatography technology to obtain reliable data about
structure-activity relationships. In parallel with PDPS, Alanex medicinal
chemists often utilize additional chemistries when such an approach is required
for the efficient modification of the current lead compounds.
 
                                       25
<PAGE>   27
 
     The Company's integrated approach to drug discovery and its PDPS technology
are largely new approaches to drug discovery. There can be no assurance that the
Company will be able to employ its methods of drug discovery successfully or
that its technologies and methodologies will lead to discovery and development
of commercial pharmaceutical products. See "Risk Factors -- New and Uncertain
Technology and Business."
 
KEY BENEFITS OF ALANEX'S DRUG DISCOVERY APPROACH
 
  VIRTUAL LIBRARY
 
     Alanex's virtual library is comprised of more than 140 million chemical
structures, any one of which can be synthesized and screened by the Company in
one or two days. Access to such a large number of structures allows Alanex to
choose optimal sets of molecules for actual synthesis of both its diverse
exploratory library and targeted libraries.
 
  LIBRARY DESIGN AND INFORMATION MANAGEMENT SOFTWARE
 
     A central feature of Alanex's technology is the Company's proprietary
software, LiBrain, that is integrated into all stages of the drug discovery
process. This software is used to build and access chemical structures from
Alanex's virtual library, to evaluate and choose compounds for the synthesis of
exploratory, targeted and analog libraries, and to track and manage all chemical
and biological data associated with the testing of libraries and discovery of a
drug candidate.
 
  DIVERSITY OF LIBRARY COMPOUNDS
 
     Alanex's exploratory library is composed of multiple sub-libraries (1,000
to 10,000 compounds each) based on a variety of different chemical "templates,"
the fundamental core of the molecules. To create these sub-libraries, Alanex has
adapted over 45 chemical reactions and is continually expanding its list of
chemical reactions. The exploratory library achieves a high level of diversity
because the diversity within each sub-library is compounded by the large number
of templates. The Company believes that this approach to combinatorial
chemistry, as opposed to utilizing larger libraries with fewer templates,
enhances the likelihood of discovery of active compounds.
 
  SYNTHESIS OF DRUG-LIKE STRUCTURES
 
     Alanex designs and synthesizes libraries focused on structures that are
expected to have drug-like characteristics, such as compact heterocylic
structures, low molecular weights and other desirable pharmacological
properties. Compounds with these structures are preferred as drug candidates
because they are more likely to be orally active and typically have longer
duration of action.
 
  SYNTHESIS OF INDIVIDUAL COMPOUNDS
 
     Alanex's combinatorial synthesis technology produces large numbers of
distinct individual compounds and avoids the disadvantages associated with the
testing of mixtures. Individual compounds can be synthesized in larger
quantities than is typical with mixtures, allow for the performance of quality
control and can be used in a wide range of assays. Alanex's library production
is largely automated, and individual compounds are synthesized at an average
rate in excess of 10,000 per month.
 
  ABILITY TO CONVERT LEAD COMPOUNDS INTO DRUG CANDIDATES
 
     Alanex's PDPS' technology integrates combinatorial, computational and
medicinal chemistries with pharmacology and high throughput screening to expand
the scope of combinatorial chemistry by providing efficient tools for the
conversion of lead compounds into drug candidates. Optimization of important
pharmacological characteristics of the lead compounds requires modification of
its chemical structure. Alanex's access to over 45 chemical reactions and its
ability to add new reactions allows it to modify lead compounds in a wide
variety of ways, thus significantly facilitating the process of combinatorial
optimization.
 
                                       26
<PAGE>   28
 
In addition, Alanex's in-house medicinal chemistry expertise provides access to
chemical structures unavailable through combinatorial chemistry.
 
ALANEX'S DRUG DISCOVERY PROGRAMS
 
     Alanex is currently advancing seven drug discovery programs in conjunction
with corporate collaborators or independently. In selecting programs, the
Company considers (i) the existence of a characterized molecular target, (ii)
the existence or adequacy of available remedies, (iii) the potential market size
for any product and (iv) a collaborator's area of interest. The table below
identifies current Alanex drug discovery programs and their molecular targets,
indications, program status and commercial rights.

    Alanex has identified a compound that meets preselected in vitro criteria
    for potency and specificity. "Lead Discovery" includes the development of
    assay systems, screening of chemical libraries and discovery of lead
    compounds.
 
  ASTRA PHARMA PAIN PROGRAM
 
     The drugs used for the treatment of severe or chronic pain are generally of
limited effectiveness or associated with problems of tolerance, addiction and
gastrointestinal side effects. As a result, there is a substantial need for
effective pain relieving agents with a more favorable side effect profile. The
recent molecular cloning of multiple opiate receptor subtypes affords the
opportunity to discover new classes of analgesics.
 
     On behalf of Astra Pharma, Alanex applied its PDPS technology and
discovered a new class of analgesic compounds that interact with a novel opiate
receptor target. From initiation of the program to production of preclinical
compounds required only 14 months. There can be no assurance that the Company
will be able to develop compounds in other programs as rapidly. These compounds
have been shown to be orally active in preclinical studies and are currently
being considered by Astra Pharma as possible clinical candidates. See
"Collaboration Agreements and Licenses."
 
  NOVO NORDISK DIABETES PROGRAMS
 
     Diabetes is a common and frequently devastating disease that can lead to
the development of debilitating and life threatening cardiovascular disease,
blindness, kidney failure and neurologic disorders. Diabetes affects seven
million to eight million individuals in the United States. Control of blood
glucose levels using insulin and oral hypoglycemic agents are the most common
forms of treatment for diabetes. However, these treatments are frequently
inadequate because they neither provide sufficient control of blood glucose
levels nor prevent the development of the serious complications associated with
the disease. Discovery of drugs that
 
                                       27
<PAGE>   29
 
augment the synthesis, release and action of insulin could improve the
regulation of blood glucose levels and potentially reduce the severity of the
complications of diabetes.
 
     Two molecular targets have been selected by Alanex and Novo Nordisk as the
basis for discovery of new drugs to treat diabetes. Addressing these two
targets, one with an agonist and one with an antagonist, may offer the
opportunity to introduce drugs with new mechanisms of action to treat diabetes
and its complications. Alanex has discovered and is optimizing lead compounds
for the agonist molecular target and is currently conducting preclinical studies
on compounds for the antagonist molecular target. See "Collaboration Agreements
and Licenses."
 
  NEUROPEPTIDE Y (NPY) ANTAGONIST PROGRAM
 
     Neuropeptide Y (NPY) is a 36-amino acid peptide that is involved in the
regulation of the cardiovascular, immune and gastrointestinal systems. NPY is
also present within nerves of the brain that regulate appetite and mood. Several
different NPY receptors have been identified, providing the opportunity to
discover NPY antagonists that are selective for modulating one among several
possible actions of NPY. Alanex has discovered detailed information on the
molecular requirements for NPY's binding to its receptors and is using this
information to discover NPY receptor antagonists for the treatment of obesity
and cardiovascular disease.
 
     Obesity. Current estimates indicate that over 20% of the United States
population is obese. Obesity is a major risk factor responsible for the
development of hypertension, diabetes, degenerative joint disease, abnormal
wound healing and other major medical problems. Recent reports indicate that
direct and indirect costs associated with obesity were greater than $68 billion
in 1990.
 
     NPY is a powerful known appetite stimulant and has been demonstrated to be
present in abnormally high amounts in the brains of obese animals. Based on
these observations, Alanex believes that a suitable antagonist could block the
effects of NPY, resulting in decreased appetite and normalization of body
weight. In addition, NPY antagonists that control obesity may also serve as
adjunctive therapy in the treatment of obesity-related diseases, such as
diabetes, hypertension and degenerative joint disease. Alanex has discovered a
lead compound that blocks NPY-induced feeding in preclinical models. This
compound is currently being evaluated for its effects on feeding and obesity in
preclinical models.
 
     Cardiovascular Disease. Cardiovascular disease, including hypertension,
ischemic organ disease (such as myocardial infarction and stroke), heart failure
and reperfusion injury, is the leading cause of human morbidity and mortality in
the United States. There are currently over 900,000 deaths per year (43% of
deaths from all causes) in the United States that are attributable to
cardiovascular disease.
 
     In humans, excessive release of NPY may elevate blood pressure, decrease
blood flow to heart muscle and impair heart function. In addition, NPY may play
a role in the development of reperfusion abnormalities that are observed
following angioplasty and stroke. The Company believes that NPY antagonists
could be useful in the treatment of some forms of cardiovascular disease. Alanex
has discovered a lead compound that is active and is being evaluated in
preclinical models for its effects on cardiovascular function.
 
  CORTICOTROPIN RELEASING FACTOR (CRF) ANTAGONIST PROGRAM
 
     Corticotropin releasing factor (CRF) is a 41-amino acid peptide that is
synthesized in the brain and is released following stress. CRF is the primary
regulator of the pituitary gland, the autonomic (involuntary) nervous system and
the behavioral responses that are produced by stress. CRF acts on the pituitary
gland to release adrenocorticotropic hormone, which in turn stimulates steroid
hormone release from the adrenal gland. Within the brain, CRF affects hormones
that control growth and reproduction and activates the autonomic nervous system
to modify cardiovascular, metabolic, gastrointestinal and immune functions.
Under appropriate circumstances, these CRF-induced responses to stress are
important to restore or maintain homeostasis. However, repeated exposure to
stress may produce depression and anxiety, as well as a number of other
disorders that result from the actions of CRF. Two different CRF receptor
subtypes are known to mediate the actions of CRF.
 
     Depression and anxiety represent major health problems throughout the
world. The lifetime prevalence in the United States for any one person of
clinical depression is 10% and of generalized anxiety is 15%. Studies
 
                                       28
<PAGE>   30
 
performed on preclinical models and human subjects indicate a potential role of
CRF in mediating depression and anxiety. Development of a potent, orally
available drug that blocks the actions of CRF could be useful in the treatment
of these indications.
 
     Alanex is using its drug discovery technologies to develop an antagonist of
CRF that can be used to treat depression and anxiety. Alanex has discovered lead
compounds that are highly active on specific CRF receptor subtypes, and these
compounds are currently being optimized and evaluated in preclinical models for
their effects on depression and anxiety.
 
  GNRH ANTAGONIST PROGRAM
 
     Gonadotropin releasing hormone (GnRH) is a decapeptide that is synthesized
in the brain and controls the pituitary and gonadal hormones that regulate
fertility. In women, this peptide is required for successful ovulation and, in
men, it is necessary for spermatogenesis. Alanex is engaged in a program to
discover orally active small molecule drugs to treat two areas of human disease
that depend on GnRH action -- endometriosis and sex-hormone dependent tumors.
The GnRH project, initiated in July 1996, utilizes a human pituitary GnRH
receptor licensed from Mount Sinai School of Medicine of the City University of
New York ("Mount Sinai"). This project is in the lead discovery phase.
 
     Endometriosis. Endometriosis is an abnormal proliferation of uterine tissue
and is dependent, in part, on the production of sex hormones. Endometriosis
affects 7% of women of reproductive age in the United States and is the major
cause of female infertility. Because GnRH controls sex hormone production,
peptide antagonists of GnRH have been used to successfully treat endometriosis.
However, this treatment involves the use of peptide analogs of GnRH that, due to
the chemical makeup of the drug, may be painful to patients. Orally active
antagonists of GnRH should be less costly, involve less patient pain and
increased patient compliance.
 
     Sex-hormone Dependent Tumors. The growth of certain tumors, such as breast
cancer, is dependent on sex hormones. The Company believes that antagonists of
GnRH may be useful in the treatment of breast cancer in women and prostate
cancer in men. Prostate cancer is the most common form of cancer in men and is
currently diagnosed at a rate of approximately 100,000 new cases per year.
Presently there are an estimated 8.5 million men with prostate cancer in the
United States. Breast cancer is the most common form of cancer in women and has
a 12% cumulative lifetime probability of developing in any particular woman.
 
  ROCHE BIOSCIENCE PAIN PROGRAM
 
     In June 1996, the Company entered into a collaboration with Roche
Bioscience to discover an antagonist for an undisclosed target for the treatment
of pain. This project is in the lead discovery phase. The Company will perform
all aspects of this drug discovery project, including high throughput screening
of its exploratory library and lead optimization to provide Roche Bioscience
with one or more drug candidates. See "-- Collaboration Agreements and
Licenses."
 
     The Company's potential products will require significant additional
preclinical and clinical development, regulatory approval and additional
investment prior to commercialization, either by the Company independently or by
others through collaborative arrangements. There can be no assurance that any
potential products will be successfully developed, prove to be safe and
efficacious in clinical trials, meet applicable regulatory standards, be capable
of being produced in commercial quantities at acceptable costs or achieve
commercial acceptance. See "Risk Factors -- Early Stage of Product Development;
Lack of Commercial Products; No Assurance of Successful Product Development."
 
STRATEGY
 
     Alanex's objective is to use its integrated combinatorial chemistry drug
discovery technology to rapidly identify lead compounds and to efficiently
optimize these leads into drug development candidates that will address disease
conditions for which existing therapies are inadequate or unavailable. Key
elements of the Company's strategy to achieve this objective include the
following:
 
                                       29
<PAGE>   31
 
  CAPITALIZE ON STRATEGIC COLLABORATIONS WITH PHARMACEUTICAL COMPANIES
 
     Alanex has established and will continue to seek collaborations with major
pharmaceutical companies. Under such collaborations, the Company's intent is to
license to its collaborators the commercial rights to compounds discovered by
the Company in exchange for upfront project initiation fees, research funding,
milestone payments and royalties on drug sales, where appropriate. This approach
is intended to capitalize on the emerging trend in the pharmaceutical industry
to outsource certain components of drug discovery that can be more efficiently
provided by firms that have unique or focused technologies.
 
  ENTER INTO STRATEGIC RELATIONSHIPS WITH BIOTECHNOLOGY COMPANIES
 
     The Company believes that, while a number of biotechnology companies have
identified biological targets, many lack an adequate supply of differentiated
chemical entities for incorporation into their assay systems for the discovery
of drugs. To access these novel targets, the Company intends to establish
collaborations with biotechnology companies that have discovered novel
biological targets. Under these collaborations, Alanex intends to screen its
exploratory library against the collaborator's proprietary targets. Unlike its
collaborations with pharmaceutical companies, the Company anticipates that it
would fund a share of the development costs in return for increased commercial
rights with respect to such products.
 
  DEVELOP AND ADVANCE INTERNAL DRUG DISCOVERY PROGRAMS
 
     Alanex will continue to develop in-house programs for the discovery of new
drugs. Alanex anticipates that it may, where appropriate, advance certain lead
compounds through the early phases of clinical development in order to retain a
larger economic interest in such products. During the course of development, the
Company may enter into a collaboration to continue clinical development or may
license a product, if approved, for manufacturing or marketing. Alanex will
develop the programs internally or, where appropriate, the Company will seek to
license proprietary biological targets from biotechnology companies, academic
and nonprofit research institutions to be the foundation of the Company's
in-house drug discovery programs. In the long term, Alanex may choose to
develop, manufacture and market its products independently.
 
COLLABORATION AGREEMENTS AND LICENSES
 
     The Company has collaborative agreements with Astra Pharma, Novo Nordisk
and Roche Bioscience, as well as a licensing agreement with Mount Sinai. The
amount and timing of resources that the collaborators devote to the
collaborations are not within the control of the Company. There can be no
assurance that such collaborators will perform their obligations as expected or
that the Company will derive any additional revenue from such collaborations.
See "Risk Factors -- Dependence on Collaborators."
 
  ASTRA PHARMA
 
     In December 1994, the Company and Astra AB entered into a three-year
collaboration agreement for the identification and optimization of lead
compounds that interact with a specific opiate receptor which may have
application in the treatment of pain. The agreement was subsequently assigned to
Astra Pharma, an affiliate of Astra AB. The Company was paid a project
initiation fee of $250,000 and Astra Pharma is obligated to make additional
payments upon the achievement of certain milestones. In addition, Astra Pharma
is obligated to provide up to $2.25 million of additional funding to support
research undertaken in connection with the agreement. To date, Alanex has
received $1.3 million under the collaboration agreement. Under the terms of the
collaboration, Astra Pharma owns all rights in and has title to any and all
compounds discovered and products developed as a result of the research
collaboration. The Company has no right to commercialize and is not entitled to
receive royalties on the sales of any products resulting from the collaboration
agreement. Astra Pharma may terminate the collaboration agreement at any time
upon three months' written notice. In the event of early termination of the
collaboration agreement, Astra Pharma will have exclusive title to all compounds
and associated intellectual property rights discovered as a result of the
collaboration.

  NOVO NORDISK
 
     In October 1995, the Company and Novo Nordisk entered into a three-year
collaboration agreement for the characterization of novel, non-peptide ligands
with desired receptor ligand binding affinities to be used to develop small
molecule drugs for the treatment of diabetes. Novo Nordisk paid the Company a
project initiation fee of $250,000 and is obligated to make additional payments
to the Company upon the achievement of certain milestones. In addition, Novo
Nordisk is obligated to provide up to $4.5 million in additional funding to
support research at the Company in the field of the collaboration. To date,
Alanex has received $1.3 million under the collaboration agreement. The
agreement provides that, in the event the collaboration results in a drug
candidate which Novo Nordisk elects to pursue to commercialization, Novo Nordisk
will be granted an exclusive worldwide license to develop and commercialize such
drug candidate. The Agreement provides for the Company to receive royalties on
the sales of any such drug. Novo Nordisk may, at any time, terminate the
collaboration upon three months' written notice. Upon any such early
termination, any licenses granted to Novo Nordisk by Alanex under the
collaboration agreement will continue in full force and effect, unless otherwise
specifically terminated.
 
  ROCHE BIOSCIENCE
 
   
     In June 1996, the Company and Roche Bioscience entered into a three-year
collaboration agreement to discover an antagonist for an undisclosed target for
the treatment of pain. The agreement provides for Roche Bioscience to pay to the
Company a nonrefundable project initiation fee of $4.0 million, one-half of
which was paid and recognized as revenue upon execution of the collaboration
agreement and one-half of which Roche will be obligated to pay on October 31,
1996. Roche Bioscience is obligated to make additional payments upon the
achievement of certain milestones. In addition, during the term of the
agreement, Roche Bioscience will provide a minimum of $5.5 million in additional
funding to support research personnel at the Company, and the Company will work
exclusively with Roche Bioscience on the selected molecular target. To date, the
Company has received $2,575,000 under the collaboration agreement. Roche
Bioscience also has the option, until January 15, 1997, to expand the field of
research to include the funding of one or more additional molecular targets. The
agreement provides Roche Bioscience with an exclusive worldwide license to
commercialize any compounds resulting from the research that are selected by
Roche Bioscience for further development and to pay royalties to Alanex on any
sales of products developed from the collaboration. Alanex will retain all
rights to compounds not selected by Roche Bioscience for development, provided
that Roche Bioscience is not developing a structurally-related compound on which
Roche Bioscience will be paying milestones and royalties to the Company, and
Alanex may pursue such compounds following termination of the collaboration.
Upon completion of the first year of the agreement, Roche Bioscience may
terminate the collaboration at any time upon six months' prior written notice.
If the collaboration agreement is terminated prior to its expiration, all
licenses granted by the parties to one another will terminate and revert back to
the respective parties, but Roche Bioscience will retain the right to
commercialize any products resulting from the research efforts under licenses
granted by the Company prior to the termination.
    
 
  MOUNT SINAI
 
     In June 1996, the Company and Mount Sinai entered into an agreement to
conduct research relating to the human GnRH receptor. Under the agreement, the
Company funded the initial phase of the research and is obligated to provide
additional funding upon the achievement of certain milestones. In connection
with the research agreement, Mount Sinai granted to the Company (i) a
non-exclusive worldwide license to develop and commercialize any products based
upon certain inventions and technologies owned by Mount Sinai relating to the
human GnRH receptor and (ii) an exclusive worldwide license to develop and
commercialize any products based upon know-how or patents or patent applications
covering inventions made during the course of the research. Pursuant to the
terms of the licenses, the Company is obligated to pay Mount Sinai a percentage
of any milestone payments received by the Company from third-party sublicenses
and royalties on sales of products. The Company may terminate the licenses upon
60 days' written notice; however, in the event of such termination, all rights
granted under the licenses will revert to Mount Sinai.

COMPETITION
 
     The pharmaceutical and biotechnology industries are subject to intense
competition and rapid and significant technological change. Many organizations
are actively attempting to identify and optimize compounds for potential
pharmaceutical development. The Company competes directly with the research
departments of pharmaceutical companies, biotechnology companies, other
combinatorial chemistry companies and research and academic institutions. Many
of these competitors have greater financial and other resources, and more
experience in research and development, than the Company. Historically,
pharmaceutical companies have maintained close control over their research
activities, including the synthesis, screening and optimization of chemical
compounds. Many of these companies, which represent the greatest potential
market for the Company's services and compounds, are developing combinatorial
chemistry and other methodologies to improve productivity. In addition, these
companies may already have large collections of compounds previously synthesized
or ordered from chemical supply catalogs or other sources against which they may
screen new targets. Other sources of compounds include compounds extracted from
natural products, such as plants and microorganisms, and compounds created using
rational drug design. Academic institutions, governmental agencies and other
research organizations are also conducting research in areas in which the
Company is working, either on their own or through collaborative efforts.
 
     The Company competes with several alternative technologies in the design
and synthesis of new chemical libraries for drug discovery programs. Alanex
competes directly with several public companies, including Arris
Pharmaceuticals, Inc., Houghten Pharmaceuticals, Inc. and Pharmacopeia, Inc., as
well as several private companies. Competition is based on the speed and
efficiency of lead compound identification, the efficiency of lead compound
optimization, product efficacy and safety and the relative speed with which the
Company or its collaborators, as appropriate, can complete the preclinical and
clinical testing and approval processes and supply commercial quantities of any
product to the market.
 
     The Company anticipates that it will face increased competition in the
future as new companies enter the market and advanced technologies become
available. The Company's processes may be rendered obsolete or uneconomical by
technological advances or entirely different approaches developed by one or more
of the Company's competitors. The existing approaches of the Company's
competitors or new approaches or technology developed by the Company's
competitors may be more effective than those developed by the Company.
 
PATENTS AND PROPRIETARY INFORMATION
 
     To date, the Company has filed six U.S. patent applications, five of which
were filed in the third quarter of 1996. Two of the applications include
composition of matter claims relating to compounds in the Company's NPY and CRF
programs. The other applications relate to various aspects of the Company's
technology, including its parallel synthesis technology and related methods and
devices. There can be no assurance, however, that patents will be issued to the
Company as a result of its pending applications or that, if issued, such patents
will be sufficiently broad to afford protection against competitors with similar
technology. The Company's success will depend in large part on its ability, and
the ability of its licensees and its licensors, to obtain patents for its
technologies and the compounds and other products, if any, resulting from the
application of such technology, to defend patents once obtained, to maintain
trade secrets and to operate without infringing upon the proprietary rights of
others, both in the United States and in foreign countries.
 
     The patent positions of pharmaceutical and biotechnology companies,
including the Company, are often uncertain and involve complex legal and factual
questions which are largely unresolved. However, disputes may arise between the
Company and other patent holders as to claims of infringement, which could
involve protracted periods of litigation. Many of the Company's competitors
have, or are affiliated with companies having, substantially greater resources
than the Company, and such competitors may be able to sustain the costs of
complex patent litigation to a greater degree and for longer periods of time
than the Company. Uncertainties resulting from the initiation and continuation
of any patent or related litigation could have a material adverse effect on the
Company's ability to compete in the marketplace pending resolution of the
disputed matters. In the event that third parties have or obtain rights to
intellectual property or technology
 
                                       32
<PAGE>   34
 
used or needed by the Company, there can be no assurance that any licenses would
be available to the Company on acceptable terms, if at all.
 
     Moreover, there can be no assurance that the Company or its customers will
be able to obtain patent protection for lead compounds or pharmaceutical
products based upon the Company's technology. There can be no assurance that any
patents issued to the Company or its collaborative partners, or for which the
Company has license rights, will not be challenged, invalidated or circumvented,
or that the rights granted thereunder will provide competitive advantages to the
Company. Litigation, which could result in substantial cost to the Company, may
be necessary to enforce the Company's patent and license rights or to determine
the scope and validity of others' proprietary rights. Further, U.S. patents do
not provide any remedies for infringement that occurred before the patent is
granted. Because patent rights are territorial, the Company may not have an
effective remedy against use of its technology in any country in which it does
not, at that time, have an issued patent.
 
     Because of the length of time and expense associated with bringing new
products through development and the length of time required for the
governmental approval process, the pharmaceutical industry has traditionally
placed considerable importance on obtaining and maintaining patent and trade
secret protection for significant new technologies, products and processes. The
Company and other biotechnology and pharmaceutical firms have applied, and are
applying, for patents for their products and certain aspects of their
technologies. The enforceability of patents issued to biotechnology and
pharmaceutical firms can be highly uncertain. Federal court decisions
establishing legal standards for determining the validity and scope of patents
in the field are in transition. For example, in a currently pending case, the
U.S. Supreme Court will consider whether to alter or replace the traditional
standard for determining patent infringement under the doctrine of equivalents.
There can be no assurance that the historical legal standards surrounding
questions of validity and scope will continue to be applied or that current
defenses as to issued patents in the field will offer protection in the future.
In addition, there can be no assurance as to the degree and range of protection
any patents will afford, whether patents will issue or the extent to which the
Company will be successful in not infringing patents granted to others.
 
     The commercial success of the Company will also depend upon avoiding the
infringement of patents issued to competitors and upon maintaining the
technology licenses upon which certain of the Company's current products are, or
any future products under development might be, based. If competitors prepare
and file patent applications in the United States that claim technology also
claimed by the Company, the Company may have to participate in interference
proceedings declared by the PTO to determine the priority of invention, which
could result in substantial cost to the Company, even if the outcome is
favorable to the Company. An adverse outcome could subject the Company to
significant liabilities to third parties and require the Company to license
disputed rights from third parties or cease using the technology. The Company is
aware of a U.S. patent issued to a third party that broadly claims the
automation of iterative parallel synthesis technology. Although the Company
believes that its current activities do not infringe this patent, there can be
no assurance that the Company's belief would be affirmed in any litigation over
the patent or that the Company's future technological developments would be
outside the scope of this patent. A U.S. patent application is maintained under
conditions of confidentiality while the application is pending in the PTO, so
that the Company cannot determine the inventions being claimed in pending patent
applications filed by its competitors in the PTO. Further, U.S. patents do not
provide any remedies for infringement that occurred before the patent is
granted.
 
     The Company currently has certain licenses from a third party and in the
future may require additional licenses from other parties to develop,
manufacture and market commercially viable products effectively. There can be no
assurance that any future licenses will be obtainable on commercially reasonable
terms, if at all, that the patents underlying such licenses will be valid and
enforceable or that the proprietary nature of the patented technology underlying
such licenses will remain proprietary.
 
     The Company relies substantially on certain technologies which are not
patentable and are therefore potentially available to the Company's competitors.
The Company also relies on certain proprietary trade secrets and know-how, which
are not patentable. Although the Company has taken steps to protect its
unpatented technologies, trade secrets and know-how, in part through the use of
confidentiality agreements
 
                                       33
<PAGE>   35
 
with its employees, consultants and certain of its contractors, there can be no
assurance that these agreements will not be breached, that the Company would
have adequate remedies for any breach, or that the Company's trade secrets will
not otherwise become known or be independently developed or discovered by
competitors.
 
GOVERNMENT REGULATION
 
     Regulation by governmental authorities in the United States and foreign
countries is a significant factor in the manufacture and marketing of any
products that may be developed by the Company or a collaborator. The Company's
products will require regulatory approval by governmental agencies prior to
commercialization. In particular, human therapeutic products are subject to
rigorous preclinical and clinical testing and other approval requirements by the
FDA and comparable agencies in foreign countries. The time required for
completing such testing and obtaining such approvals is uncertain, although
satisfaction of these requirements typically takes a number of years and varies
substantially based on the type, complexity and novelty of the pharmaceutical
product. In addition, delays or rejections may be encountered based on changes
in FDA or foreign regulatory policy during the period of product development and
testing. Various federal statutes and regulations also regulate the
manufacturing, safety, labeling, storage, recordkeeping and marketing of such
products. The lengthy process of obtaining regulatory approvals and ensuring
compliance with appropriate federal statutes and regulations requires the
expenditure of substantial resources. Any delay or failure by the Company or its
collaborators or licensees to obtain regulatory approval could adversely affect
the commercialization of such products, the Company's ability to receive product
or royalty revenue and its liquidity and capital resources.
 
     Preclinical studies are generally conducted in the laboratory to evaluate
the potential efficacy and the safety of a therapeutic product. The results of
these studies are submitted to the FDA as part of an Investigational New Drug
application, which must be reviewed by the FDA before human clinical testing can
begin. Once the FDA is satisfied with the submission, the clinical trial process
can commence. Typically, clinical evaluation involves three sequential phases,
which may overlap. During Phase I, clinical trials are conducted with a
relatively small number of subjects to determine the early safety profile of a
drug, as well as the pattern of drug distribution and drug metabolism by the
subject. In Phase II, trials are conducted with groups of patients afflicted by
a specific target disease to determine preliminary efficacy, dosage tolerance
and optimal dosage, and to gather additional safety data. In Phase III,
large-scale, multicenter comparative trials are conducted with patients
afflicted with a specific target disease to provide data for the statistical
proof of efficacy and safety as required by the FDA and others. The FDA, the
clinical trial sponsor or the investigator may suspend clinical trials at any
time if it believes that clinical subjects are being exposed to an unacceptable
health risk.
 
     The results of preclinical and clinical testing are submitted to the FDA in
the form of a New Drug Application ("NDA"). In responding to an NDA, the FDA may
grant marketing approval, request additional information or deny the application
if the FDA determines that the application does not satisfy its regulatory
approval criteria. Furthermore, FDA or governmental approval of any products
developed by the Company, independently or with its collaborators, may entail
limitations on the indicated uses for which such products may be marketed. There
can be no assurance that approvals will be granted on a timely basis, if at all
or, if granted, whether such approvals will be sufficiently broad with respect
to the indicated uses for the product to be of significance to the Company. The
failure to obtain timely permission for clinical testing or timely approval for
product marketing would materially affect the Company. Product approvals may
subsequently be withdrawn if compliance with regulatory standards is not
maintained or if problems occur after the product reaches the market. The FDA
may require testing and surveillance programs to monitor the effect of a new
product and may prevent or limit future marketing of the product based on the
results of these postmarketing programs.
 
     The Company is subject to various federal, state and local laws,
regulations and recommendations relating to safe working conditions, laboratory
and manufacturing practices, the experimental use of animals and the use and
disposal of hazardous or potentially hazardous substances, including radioactive
compounds and infectious disease agents, used in connection with the Company's
work. The extent and character of
 
                                       34
<PAGE>   36
 
governmental regulation that might result from future legislation or
administrative action cannot be accurately predicted.
 
FACILITIES
 
     The Company currently leases approximately 17,000 square feet of laboratory
and office space in San Diego, California under a seven-year operating lease
which expires in May 2002. The Company has an option to lease an additional
3,000 square feet of administrative space in its current facility. The Company
is exploring alternatives to expand its current facilities to meet its planned
expansion and believes that such facilities will be available on commercially
reasonable terms.
 
EMPLOYEES
 
     As of September 1, 1996, the Company had 48 full-time employees. Of the 48
full-time employees, 39 were employed in research. Twenty-two of the Company's
employees have Ph.D.s and one has an M.D. None of the Company's employees are
covered by collective bargaining agreements and management considers
relationships with employees to be good.
 
LEGAL PROCEEDINGS
 
     The Company is not a party to any material legal proceedings.

BOARD OF DIRECTORS
 
     The Company currently has authorized five directors. The Company intends to
seek additional members of the Board of Directors upon the completion of this
offering. In accordance with the Company's Certificate of Incorporation to be
effective upon the completion of this offering, the Board of Directors will be
divided into three classes with staggered three-year terms. Class I will consist
of Dr. Brown, Class II will consist of Dr. Polinsky and Dr. Hagler, Class III
will consist of Mr. Jessen and Dr. Rink. At each annual meeting of stockholders
after the initial classification, the successors to directors whose term will
then expire will be elected to serve from the time of election and qualification
until the third annual meeting following election. Any additional directorships
resulting from an increase in the number of directors will be distributed among
the three classes so that, as nearly as possible, each class will consist of
one-third of the directors. This classification of the Board of Directors may
have the effect of delaying or preventing changes in control or management of
the Company.
 
COMMITTEES OF THE BOARD OF DIRECTORS
 
     The Audit Committee of the Board of Directors, composed of Dr. Hagler and
Mr. Jessen, was formed in July 1996 to review the internal accounting procedures
of the Company and consult with and review the services provided by the
Company's independent auditors. The Compensation Committee of the Board of
Directors, composed of Dr. Hagler and Mr. Jessen, was also formed in July 1996
to review and recommend to the Board of Directors the compensation and benefits
of all officers of the Company and review general policy relating to
compensation and benefits of employees of the Company. The Compensation
Committee will also administer the issuance of stock options and other awards
under the Company's 1993 Stock Plan and 1996 Equity Incentive Plan.
 
DIRECTOR COMPENSATION
 
     Directors currently do not receive any cash compensation from the Company
for their service as members of the Board of Directors, although they are
reimbursed for certain expenses in connection with attendance at Board of
Directors and Committee meetings.
 
     In January 1994, the Company issued and sold to Dr. Hagler, pursuant to the
Company's 1993 Stock Plan, 140,000 shares of restricted stock, at a price of
$0.10 per share (the then fair market value per share of the Common Stock as
determined in good faith by the Company's Board of Directors). These shares
vested over the 24-month period ended January 1996. In September 1996, the
Company granted to Dr. Rink an option to purchase 60,000 shares of Common Stock
of the Company at an exercise price of $1.50 per share. Such option has a term
of ten years and vests monthly and ratably over a three-year period from the
date of grant.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     Until July 1996, the Company did not have a Compensation Committee of the
Board of Directors, and the entire Board of Directors participated in all
compensation decisions. In July 1996, the Board of Directors formed the
Compensation Committee and appointed Dr. Hagler and Mr. Jessen as its members.
No member of the Compensation Committee was, at any time during the fiscal year
ended December 31, 1995 or at any other time, an officer or employee of the
Company. Three of the Company's directors have acquired shares of Common Stock.
See "Certain Transactions" and "Principal Stockholders."

scientists with expertise in fields related to the Company's programs. The SAB
advises the Company on specific scientific and technical issues. SAB members are
compensated on a time-and-expenses basis and have from time to time received
options to purchase shares of Common Stock. All of the SAB members are employed
by other companies or institutions and may have commitments to, or consulting or
advisory contracts with, other entities which may conflict with
 
                                       38

an exercise price of $0.10 per share were granted to Drs. Brown and Polinsky.
 
AGGREGATED OPTION EXERCISES IN LAST FISCAL YEAR AND FISCAL YEAR-END OPTION
VALUES
 
     No options were exercised during the fiscal year ended December 31, 1995 or
held at year end by the Named Executive Officers.
 
STOCK OPTION AND EQUITY INCENTIVE PLANS
 
     The Company currently maintains two stock option plans. The Company's 1993
Stock Plan (the "1993 Plan"), covering an aggregate of 1,350,000 shares of
Common Stock, was adopted by the Board in November 1993 and amended and restated
in December 1993 and, subject to stockholder approval, in July 1996. The
Company's 1996 Equity Incentive Plan (the "1996 Plan"), covering an aggregate of
500,000 shares of Common Stock, was adopted by the Board, subject to stockholder
approval, in July 1996. Unless sooner terminated by the Board, the 1993 Plan
will terminate in November 2003 and the 1996 Plan will terminate in July 2006.
The 1993 Plan and the 1996 Plan are referred to herein as the "Plans."
 
     The Plans are administered by the Board, unless the Board delegates
authority to a committee composed of members of the Board. Subject to certain
limitations set forth in the Plans, the Board has the authority to select the
persons to whom rights under the Plans (the "Stock Awards") will be granted, to
determine whether a Stock Award will be an incentive stock option (within the
meaning of Section 422 of the Internal Revenue Code (the "Code")) (an "Incentive
Stock Option"), an option that does not qualify as an Incentive Stock Option (a
"Nonqualified Stock Option" and, together with Incentive Stock Options, the
"Options"), a stock bonus, a right to purchase restricted stock or a combination
of the foregoing, and to specify the type of consideration to be paid to the
Company upon exercise of a Stock Award. Incentive Stock Options may be granted
only to employees of the Company and, subject to certain limitations set forth
in the Plans, Stock Awards other than Incentive Stock Options may be granted to
employees and directors of and consultants to the Company.
 
     The maximum term of Options granted under the Plans is ten years. The
exercise price of Incentive Stock Options must be equal to at least 100% of the
fair market value of the Common Stock on the date of grant. The exercise price
of Incentive Stock Options granted under the Plans to any person holding more
than 10% of the total combined voting power of all classes of stock of the
Company must be equal to at least 110% of the fair market value of the Common
Stock on the date of grant and the term of such option cannot exceed five years.
To the extent that the aggregate fair market value of Common Stock with respect
to which Incentive Stock Options granted to any person are first exercisable in
any calendar year exceeds $100,000, the Incentive Stock Options or portions
thereof which exceed such limit shall be treated as Nonqualified Stock Options.
The exercise price of Nonqualified Stock Options must be equal to at least 85%
of the fair market value of the Common Stock on the date of grant. Common Stock
subject to Options granted under the Plans that expire or otherwise terminate
without full exercise shall again become available for issuance under the
respective Plans.
 
     With certain limited exceptions, Options granted under the Plans are
non-transferable. Generally, Options granted under the Plans expire three months
after the termination of an optionee's employment or other service relationship
with the Company, except that Nonqualified Stock Options granted under the 1993
 
                                       40
<PAGE>   42
 
Plan generally expire six months after such termination. In general, if an
optionee is disabled while in an employment or service relationship with the
Company, Options granted under the Plans may be exercised up to twelve months
following such optionee's disablement. In general, if an optionee dies while in
an employment or service relationship with the Company, Options granted under
the 1993 Plan may be exercised up to twelve months after the death of such
optionee while Options granted under the 1996 Plan may be exercised up to 18
months after the death of such optionee.
 
     Subject to certain limitations contained in the Plans, the purchase price
of Common Stock subject to a stock purchase agreement granted pursuant to the
Plans, as well as the form of consideration to be paid to the Company upon the
exercise of an Option, may be determined by the Board. In addition, the Board
has the authority under the Plans to award stock pursuant to a stock bonus in
consideration of past services actually rendered to the Company. Stock bonuses
and restricted stock purchase awards granted under the Plans are generally
non-transferable and the Common Stock awarded or sold pursuant to a stock bonus
or restricted stock purchase agreement may be subject to a repurchase option in
favor of the Company.
 
     As of September 1, 1996, the Company had granted Options under the 1993
Plan to purchase an aggregate of 852,359 shares (net of cancellations) at
exercise prices ranging from $0.10 to $1.50 per share and 490,000 shares of
Common Stock had been issued as restricted stock under the 1993 Plan, all of
which is currently vested. As of September 1, 1996, no Stock Awards had been
granted under the 1996 Plan.
 
     In the event of a merger or consolidation involving the Company, the Board
has discretion to provide that all Stock Awards outstanding under the Plans will
be assumed by the successor corporation or substituted with similar Stock Awards
or, if such Stock Awards are not assumed or substituted, then, with respect to
Stock Awards held by persons performing services as employees, directors or
consultants, such Stock Awards will vest and become immediately exercisable
prior to such event.
 
STOCK OPTIONS GRANTED OUTSIDE OF THE 1993 PLAN AND THE 1996 PLAN
 
     The Company has from time to time granted options to purchase shares of
Common Stock outside of the 1993 Plan and the 1996 Plan ("Non-Plan Options") to
certain directors, officers and employees of the Company. As of September 1,
1996, Non-Plan Options were outstanding to purchase an aggregate of 210,000
shares of Common Stock with exercise prices ranging from $0.10 to $1.50 (and a
weighted average exercise price of $0.50 per share), and no Non-Plan Options had
been exercised. These Non-Plan Options vest monthly and ratably over a
three-year period. The Non-Plan Options have a term of ten years, except that
Non-Plan Options generally expire 30 days after the termination of an optionee's
employment or other service relationship with the Company. In general, if an
optionee dies while in an employment or service relationship with the Company,
that person's option may be exercised up to six months after his death.
 
EMPLOYEE STOCK PURCHASE PLAN
 
     In July 1996, the Board adopted, subject to stockholder approval, the
Employee Stock Purchase Plan (the "Purchase Plan") covering an aggregate of
125,000 shares of Common Stock. The Purchase Plan is intended to qualify as an
employee stock purchase plan within the meaning of Section 423(b) of the Code.
Under the Purchase Plan, the Board may authorize participation by eligible
employees, including officers, in periodic offerings of up to 27 months in
length. The Purchase Plan provides that the Board shall specify certain terms
and conditions that will apply to each such offering within the parameters set
forth in the Purchase Plan. The initial offering under the Purchase Plan will
commence on the date of this Prospectus and terminate on August 31, 1998.
Employees who receive annual compensation in excess of $90,000 (the "Eligibility
Cut-off") will not be eligible to participate in the initial offering. The Board
has the authority to increase or decrease the amount of the Eligibility Cut-off
from time to time.
 
     Except as set forth above, employees who satisfy the applicable length of
service requirement specified by the Board for an offering are eligible to
participate in the Purchase Plan for the period of such offering if they are
customarily employed by the Company or an affiliate of the Company for at least
20 hours per week and at least five months per calendar year. Participating
employees may elect to have up to 15% of their earnings (or such lesser amount
specified by the Board for a particular offering period) withheld from their
paychecks pursuant to the Purchase Plan. The amount withheld is then used to
purchase shares of Common Stock from
 
                                       41
<PAGE>   43
 
the Company on specified purchase dates determined by the Board. The price of
Common Stock purchased under the Purchase Plan generally will be equal to 85% of
the lower of the fair market value of the Common Stock at the commencement date
of each offering period or the specified purchase date. Employees may end their
participation in the offering at any time during the offering period, and
participation ends automatically on termination of employment with the Company.
Under the Purchase Plan, rights of any employee to purchase stock under all
employee stock purchase plans may not accrue at a rate that exceeds $25,000 in
fair market value per calendar year in which rights are outstanding, and no
person may purchase shares to the extent such person owns or would own 5% or
more of the total combined value or voting power of all classes of stock of the
Company and its affiliates (including stock subject to options).
 
     In the event of a merger, reorganization, consolidation or liquidation
involving the Company, the Board has discretion to provide that each right to
purchase Common Stock will be assumed or an equivalent right substituted by the
successor corporation, or the Board may shorten the offering period and provide
for all sums collected by payroll deductions to be applied to purchase stock
immediately prior to such merger or other transaction. The Board has the
authority to amend or terminate the Purchase Plan at any time; however, no such
action may adversely affect any outstanding rights to purchase Common Stock
under the Purchase Plan.
 
401(k) PLAN
 
     The Company maintains a tax-qualified employee savings and retirement plan
under Section 401(k) of the Code (the "401(k) Plan") covering all of the
Company's employees who have attained the age of 18 years and who have completed
six months of employment. Pursuant to the 401(k) Plan, employees may elect to
reduce their current compensation in an amount not to exceed the statutory
prescribed annual limit ($9,500 in 1996) and have the amount of such reduction
contributed to the 401(k) Plan. The Company may make discretionary contributions
to the 401(k) Plan, including contributions matching all or some portion of the
elective contributions made by employees. The Company does not currently match
employees' contributions. Any contributions made to the 401(k) Plan by the
Company generally vest proportionally over five years of service. The 401(k)
Plan is intended to qualify under Section 401 of the Code so that contributions
by employees or by the Company to the 401(k) Plan, and income earned on plan
contributions, are not taxable to employees until withdrawn from the 401(k)
Plan, and so that contributions by the Company, if any, will be deductible by
the Company when made. The 401(k) Plan may be amended or discontinued at any
time by the Company.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
     The Company's Bylaws provide that the Company will indemnify its directors
and executive officers and may indemnify its other officers, employees and other
agents to the fullest extent not prohibited by Delaware law as in effect from
time to time. The Company is also empowered under its Bylaws to enter into
indemnification contracts with its directors and officers and to purchase
insurance on behalf of any person it is required or permitted to indemnify.
Pursuant to this provision, the Company has entered into indemnification
agreements with each of its directors and executive officers.
 
     In addition, the Company's Certificate of Incorporation provides that
directors of the Company shall not be personally liable to the Company or its
stockholders for monetary damages for any breach of fiduciary duty as a
director, except for liability (i) for any breach of the directors' duty of
loyalty to the Company or its stockholders, (ii) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) in respect of certain unlawful payments of dividends or unlawful
stock repurchases or redemptions as provided in Section 174 of the Delaware
General Corporation Law or (iv) for any transaction from which the director
derives any improper personal benefit. The Certificate of Incorporation also
provides that if the Delaware General Corporation Law is amended after the
approval by the Company's stockholders of the Certificate of Incorporation to
authorize corporate action further eliminating or limiting the personal
liability of directors, then the liability of the Company's directors shall be
eliminated or limited to the fullest extent permitted by the Delaware General
Corporation Law. The provision also does not affect a director's
responsibilities under any other law, such as the federal securities laws or
state or federal environmental laws.

                              CERTAIN TRANSACTIONS
 
     Prior to November 1993, the Company's operations were conducted by the
Partnership. Effective as of November 22, 1993, the Partnership was reorganized
into the Company through a contribution and exchange transaction (the "Roll-Up")
pursuant to which the holders of general and limited partnership interests in
the Partnership received 2,450,000 shares of the Company's Common Stock in
exchange for their respective partnership interests in the Partnership. Of these
shares, Debar, a principal stockholder of the Company and the holder of a
partnership interest in the Partnership, received 2,418,500 shares. In
connection with the Roll-Up, Marvin R. Brown, President, Chief Executive Officer
and a director of the Company and Alexander Polinsky, Vice President of
Chemistry, Chief Scientific Officer and a director of the Company each
contributed his equity interest in Plictrix, Inc., a California corporation and
a general partner of the Partnership ("Plictrix"), to the Company in exchange
for 525,000 shares and 175,000 shares, respectively, of Common Stock, and
Plictrix became a wholly owned subsidiary of the Company. The Roll-Up was
effected to change the form of entity under which the Company's operations were
conducted.
 
     In April 1994, the Company entered into a collaboration agreement with
Amgen under which Alanex granted to Amgen a worldwide exclusive license to drugs
discovered by Alanex to treat neurological diseases and a worldwide
non-exclusive license to Alanet, a proprietary software program developed by the
Company to analyze peptides. In connection with the collaboration agreement, the
Company issued to Amgen 2,978,182 shares of Series A Preferred Stock at a
purchase price of $1.51 per share and a warrant to purchase 703,636 shares of
Common Stock at an exercise price of $0.005 per share. As of June 1996, the
Company had received a total of $5,280,000 in contract research revenue under
the collaboration agreement.
 
     In June 1996, the collaboration agreement between the Company and Amgen was
terminated by Amgen. In connection with the termination of the Amgen agreement,
(i) except as set forth below, all rights to the Company's technology reverted
to the Company, (ii) Amgen's warrant to purchase 703,636 shares of Common Stock
was canceled and the Company issued a new warrant to Amgen to purchase 450,000
shares of Common Stock at an exercise price of $1.51 per share with a term of
seven years and (iii) the Company redeemed Amgen's 2,978,182 shares of Series A
Preferred Stock (representing all of the issued and outstanding Preferred Stock
of the Company), at a repurchase price of $1.51 per share, payable with an
unsecured, non-interest-bearing promissory note for $4,500,000 due June 28,
2001. In addition, under the termination agreement, Alanex is obligated to
provide to Amgen, on a non-exclusive basis, on or before October 28, 1996,
certain compounds that were included in the Alanex technology licensed to Amgen
under the collaboration agreement. In exchange for such compounds, Amgen will
pay Alanex $400,000. In connection with the termination, all licenses, options
and other rights to the Company's technology granted to Amgen under the
collaboration agreement were terminated.
 
     In November 1993, in connection with the purchase of 350,000 shares of
Common Stock, Dr. Polinsky, Vice President of Chemistry, Chief Scientific
Officer and a director of the Company, borrowed $17,500 pursuant to a promissory
note. The promissory note is secured by the shares purchased and bears interest
at the rate of 6.75% per annum. Payments of principal and accrued interest are
payable in three equal annual installments beginning in November 1994; however,
in the event Dr. Polinsky's employment by, or association with, the Company is
terminated for any reason, all remaining unpaid principal and accrued interest
will be accelerated and become due and payable immediately after such
termination or disassociation. The shares of Common Stock pledged to secure the
promissory note will be released from pledge at the rate of 20 shares for each
$1.00 in principal amount of indebtedness paid. In fiscal 1995, the Company
forgave $7,459 of Dr. Polinsky's indebtedness owed to the Company under the
promissory note. As of September 1, 1996, the outstanding principal and accrued
interest under the promissory note was $12,717.
 
     In November 1995, Dr. Polinsky also borrowed $50,000 from the Company
pursuant to an unsecured promissory note bearing interest at the rate of 6.75%
per annum. Accrued interest on the promissory note is payable in three equal
annual installments commencing November 1996, with the entire principal amount
and any accrued and unpaid interest becoming due in November 1998. As of
September 1, 1996, the outstanding principal and accrued interest under the
promissory note was $52,780.

    respect to all shares of Common Stock shown as beneficially owned by them.
    Shares subject to options that are exercisable within 60 days of September

    percentage ownership of any other person. Applicable percentage of
    beneficial ownership is based on 3,747,635 shares of Common Stock
    outstanding as of September 1, 1996, and 6,247,635 shares of Common Stock
    outstanding after completion of this offering. Except as set forth above,

                          DESCRIPTION OF CAPITAL STOCK
 
     The Company intends to reincorporate in Delaware immediately prior to the
completion of this offering. The authorized capital stock of the Company
consists of 40,000,000 shares of Common Stock, $.001 par value, and 10,000,000
shares of Preferred Stock, $.001 par value.
 
COMMON STOCK
 
     As of September 1, 1996, there were issued and outstanding 3,747,635 shares
of Common Stock held by 15 holders of record.
 
     Holders of Common Stock are entitled to one vote for each share held of
record on all matters submitted to a vote of the stockholders. Subject to
preferences that may be applicable to any outstanding shares of Preferred Stock,
holders of Common Stock are entitled to receive ratably such dividends, if any,
as may be declared by the Board of Directors out of funds legally available for
the payment of dividends. See "Dividend Policy."
 
     In the event of a liquidation, dissolution or winding up of the Company,
holders of Common Stock are entitled to share ratably in all assets remaining
after payment of liabilities and liquidation preferences of any outstanding
shares of Preferred Stock. Holders of Common Stock have no preemptive rights or
rights to convert their Common Stock into any other securities. There are no
redemption or sinking fund provisions applicable to the Common Stock. All
outstanding shares of Common Stock are validly issued, fully paid and
nonassessable. All shares of Common Stock issuable upon conversion of the
outstanding shares of Preferred Stock will be validly issued, fully paid and
nonassessable upon such conversion.
 
PREFERRED STOCK
 
     The Board of Directors has the authority, without further action by the
stockholders, to issue up to 10,000,000 shares of Preferred Stock in one or more
series and to fix the designations, powers, preferences, privileges, and
relative participating, optional or special rights and the qualifications,
limitations or restrictions thereof, including dividend rights, conversion
rights, voting rights, terms of redemption and liquidation preferences, any or
all of which may be greater than the rights of the Common Stock. The Board of
Directors, without stockholder approval, can issue Preferred Stock with voting,
conversion or other rights that could adversely affect the voting power and
other rights of the holders of Common Stock. Preferred Stock could thus be
issued quickly with terms calculated to delay or prevent a change in control of
the Company or make removal of management more difficult. Additionally, the
issuance of Preferred Stock may have the effect of decreasing the market price
of the Common Stock, and may adversely affect the voting and other rights of the
holders of Common Stock. There are currently no shares of Preferred Stock
outstanding, and the Company has no current plans to issue any of the Preferred
Stock.

WARRANTS
 
     As of September 1, 1996, there was a warrant outstanding to purchase
450,000 shares of Common Stock (the "Warrant") at an exercise price of $1.51 per
share. The Warrant has a term of seven years. The Warrant was issued to Amgen in
June 1996 in connection with the termination of a collaboration agreement
between the Company and Amgen. See "Certain Transactions."
 
DELAWARE LAW AND CERTAIN CHARTER PROVISIONS
 
     The Company is subject to the provisions of Section 203 of the Delaware
General Corporation Law (the "Delaware Law"), an antitakeover law. In general,
the statute prohibits a publicly held Delaware corporation from engaging in a
"business combination" with an "interested stockholder" for a period of three
years after the date of the transaction in which the person became an interested
stockholder, unless the business combination is approved in a prescribed manner.
For purposes of Section 203, a "business combination" includes a merger, asset
sale or other transaction resulting in a financial benefit to the interested
stockholder, and an "interested stockholder" is a person who, together with
affiliates and associates, owns (or within the three preceding years, did own)
15% or more of the corporation's voting stock.
 
     The Company's Certificate of Incorporation and Bylaws include a number of
provisions that may have the effect of deterring hostile takeovers or delaying
or preventing changes in control of the Company. The Company's Certificate of
Incorporation provides that, upon the completion of this offering, the Board of
Directors will be divided into three classes of directors, with each class
serving a staggered three-year term. The classification system of electing
directors may tend to discourage a third party from making a tender offer or
otherwise attempting to obtain control of the Company and may maintain the
composition of the Board of Directors, as the classification of the Board of
Directors generally increases the difficulty of replacing a majority of
directors. In addition, the Company's Certificate of Incorporation provides that
all stockholder action must be effected at a duly called meeting of stockholders
and not by a consent in writing. The Company's Bylaws limit who may call a
special meetings of the stockholders. Further, the Company's Certificate of
Incorporation does not include a provision for cumulative voting for directors.
Under cumulative voting, a minority stockholder holding a sufficient percentage
of a class of shares may be able to ensure the election of one or more
directors. Finally, the Company's Bylaws establish procedures, including advance
notice procedures with regard to the nomination of candidates for election as
directors and stockholder proposals. These and other provisions of the
Certificate of Incorporation and Bylaws could discourage potential acquisition
proposals and could delay or prevent a change in control of management of the
Company. Such provisions also may have the effect of preventing changes in the
management of the Company. See "Risk Factors -- Antitakeover Provisions."
 
TRANSFER AGENT AND REGISTRAR
 
     American Stock Transfer & Trust Company has been appointed as the transfer
agent and registrar for the Company's Common Stock.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Prior to this offering there has been no public market for the Common
Stock, and no prediction can be made regarding the effect, if any, that market
sales of shares or the availability of shares for sale will have on the market
price prevailing from time to time. As described below, only a limited number of
shares are currently available for sale, or will be available for sale shortly
after this offering, due to certain contractual and legal restrictions on
resale. Nevertheless, sales of substantial amounts of Common Stock in the public
market after the restrictions lapse could adversely affect the prevailing market
price.
 
     Upon completion of this offering, the Company will have outstanding
6,247,635 shares of Common Stock. Of these shares, all of the 2,500,000 shares
of Common Stock sold in this offering will be freely tradable (unless such
shares are held by an "affiliate" of the Company as such term is defined in the
Securities Act) without restriction or registration under the Securities Act.
The remaining 3,747,635 shares are Restricted
 
                                       47
<PAGE>   49
 
Shares and are eligible for public sale only if registered under the Securities
Act or sold in accordance with Rule 144 or Rule 701 thereunder, which rules are
summarized below. As a result of the contractual restrictions described below
and the provisions of Rule 144 or Rule 701, additional shares will be available
for sale in the public market as follows: (i) no Restricted Shares will be
eligible for immediate sale in the public market on the date of this Prospectus,
(ii) 2,973,715 Restricted Shares (plus 522,182 shares of Common Stock issuable
to employees pursuant to stock options that are then vested) will be eligible
for sale upon expiration of lock-up agreements (as described below) 180 days
after the date of this Prospectus and (iii) an additional 773,920 Restricted
Shares will be eligible for sale from time to time hereafter upon expiration of
their respective two-year holding periods under Rule 144.
 
     The Company's executive officers, directors and stockholders, who own all
of the Restricted Shares, have agreed, subject to certain exceptions, that they
will not, without the prior written consent of PaineWebber Incorporated, offer,
sell, contract to sell, grant any option to purchase or otherwise dispose of any
shares of Common Stock or securities convertible into or exercisable or
exchangeable for Common Stock for a period of 180 days from the date of this
Prospectus (the "Lockup Period"). PaineWebber Incorporated, in its sole
discretion at any time and without notice, may release any or all shares from
the lockup agreements and permit holders of the shares to resell all or any
portion of their shares at any time prior to the expiration of the Lockup
Period.
 
     In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this Prospectus, any holder of Restricted Shares, including an
affiliate of the Company, as to which at least two years have elapsed since the
later of the date of their acquisition of such Restricted Shares from the
Company or an affiliate, would be entitled, within any three-month period, to
sell a number of shares that does not exceed the greater of 1% of the then
outstanding shares of Common Stock (approximately 62,476 shares immediately
after the completion of this offering assuming no exercise of the Underwriters'
over-allotment option) or the average weekly trading volume of the Common Stock
in the over-the-counter market during the four calendar weeks preceding the date
on which notice of the sale is filed with the Commission. Sales under Rule 144
are subject to certain requirements relating to manner of sale, notice and
availability of current public information about the Company. However, a person
(or persons whose shares are aggregated) who is not deemed to have been an
affiliate of the Company at any time during the 90 days immediately preceding
the sale and who owns beneficially Restricted Shares is entitled to sell such
shares under Rule 144(k) without regard to the limitations described above,
provided that at least three years have elapsed since the date the shares were
acquired from either the Company or from an affiliate of the Company.
 
     Subject to certain limitations on the aggregate offering price of a
transaction and other conditions, Rule 701 may be relied upon with respect to
the resale of securities originally purchased from the Company by its employees,
directors, officers, consultants or advisers prior to the completion of this
offering, pursuant to written compensatory benefit plans or written contracts
relating to the compensation of such persons. In addition, the Commission has
indicated that Rule 701 will apply to stock options granted by the Company
before this offering, along with the shares acquired upon exercise of such
options. Securities issued in reliance on Rule 701 are deemed to be Restricted
Shares and, beginning 90 days after the date of this Prospectus (unless subject
to the contractual restrictions described above), may be sold by persons other
than affiliates, subject only to the manner of sale provisions of Rule 144 and
by affiliates under Rule 144 without compliance with its two-year minimum
holding period requirements.
 
     The Company intends to file a registration statement under the Securities
Act covering (i) 1,350,000 shares of Common Stock issuable under the 1993 Plan,
(ii) 500,000 shares of Common Stock issuable under the 1996 Plan, (iii) 150,000
shares of Common Stock issuable upon exercise of options issued outside of the
1993 Plan and the 1996 Plan and (iv) 125,000 shares of Common Stock issuable
under the Purchase Plan. Such registration statement is expected to be filed
soon after the date of this Prospectus and will become effective upon filing.
Accordingly, the shares registered under such registration statement will be
available for sale in the public market, unless such shares are subject to
vesting restrictions with the Company or the contractual restrictions described
above.

     The Underwriting Agreement provides that the obligations of the
Underwriters to purchase the shares of Common Stock listed above are subject to
certain conditions. The Underwriting Agreement also provides that the
Underwriters are committed to purchase all of the shares of Common Stock offered
hereby, if any are purchased (without consideration of any shares that may be
purchased through the Underwriters' over-allotment option).
 
     The Representatives have advised the Company that the Underwriters propose
to offer the shares of Common Stock to the public at the public offering price
set forth on the cover page of this Prospectus and to certain dealers at such
price less a concession to other dealers not in excess of $  per share; and that
the Underwriters and such dealers may reallow a concession to other dealers not
in excess of $  per share. After the initial public offering of the Common
Stock, the public offering price, the concessions to selected dealers and
reallowance to other dealers may be changed by the Representatives.
 
     At the request of the Company, the Underwriters have reserved up to 125,000
shares of Common Stock for sale at the initial public offering price to
employees, business associates and related persons of the Company. The number of
shares of Common Stock available for sale to the general public will be reduced
to the extent such persons purchase such reserved shares. Any reserved shares
which are not so purchased will be offered by the Underwriters to the general
public on the same basis as the other shares offered hereby.
 
     The Company has granted to the Underwriters an option, exercisable during
the 30-day period after the date of this Prospectus, to purchase up to an
additional 375,000 shares of Common Stock at the initial public offering price,
less the underwriting discounts and commissions set forth on the cover page of
this Prospectus. The Underwriters may exercise such option only to cover
over-allotments, if any, incurred in the sale of the shares of Common Stock that
the Underwriters have agreed to purchase. To the extent the Underwriters
exercise such option, each of the Underwriters will become obligated, subject to
certain conditions, to purchase approximately the same percentage of such
additional shares of Common Stock as is approximately equal to the percentage of
shares of Common Stock that each is obligated to purchase as shown in the table
set forth above.
 
     The representatives have informed the Company that they do not intend to
confirm sales to any account over which they exercise discretionary authority.
 
     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, or to contribute to
payments that the Underwriters may be required to make in respect thereof.
 
     The Company, its directors and executive officers and certain stockholders
have agreed not to offer, sell, contract to sell or grant any option to purchase
or otherwise dispose of any shares of Common Stock owned by them prior to the
expiration of 180 days from the date of this Prospectus, except (i) for shares
of Common Stock offered hereby, (ii) with the prior written consent of
PaineWebber Incorporated, and (iii) in the case of
 
                                       49

the Company, for the issuance of shares of Common Stock upon the exercise of
options or the grant of options to purchase shares of Common Stock.
 
     Prior to this offering, there has been no public market for the Common
Stock of the Company. Accordingly, the initial public offering price will be
determined by negotiations among the Company and the Representatives. Among the
factors to be considered in determining the initial public offering price will
be the technology base of the Company, the quality and experience of the
Company's scientific talent, the previous experience of the Company's executive
officers, the medical and research applications and potential markets to be
addressed by the Company's product development programs, the market prices of
publicly traded stock of comparable companies in recent periods and the general
condition of the securities markets at the time of the offering.
 
                                 LEGAL MATTERS

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholders
Alanex Corporation:
 
     We have audited the accompanying consolidated balance sheets of Alanex
Corporation and subsidiary as of December 31, 1994 and 1995, and the related
consolidated statements of operations, stockholders' equity, and cash flows for
each of the years in the three-year period ended December 31, 1995. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Alanex
Corporation and subsidiary as of December 31, 1994 and 1995, and the results of
their operations and their cash flows for each of the years in the three-year
period ended December 31, 1995, in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
       DECEMBER 31, 1994 AND 1995 (AUDITED) AND JUNE 30, 1996 (UNAUDITED)
 
(1) ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization and Reorganization
 
     Alanex Corporation (the "Company") was incorporated in November 1993, under
the laws of the State of California. The Company is a drug discovery company
that is applying its highly integrated and comprehensive approach to rapidly and
cost-effectively discover and optimize novel, small molecule drug candidates.
 
     Prior to November 1993, the Company's operations were conducted through
Alanex, L.P., a California limited partnership ("Alanex") and Plictrix, Inc.
("Plictrix"), the general partner of Alanex. In 1993, the partners approved the
reorganization of Alanex and Plictrix to form the Company effective in November
1993. In conjunction with this transaction, the Company issued 2,450,000 shares
of common stock to the partners of Alanex and 700,000 shares to stockholders of
Plictrix in exchange for their respective ownership interests. The transaction
has been accounted for as a reorganization of entities under common control,
using historical cost. The Company has restated all historical financial
information to reflect the reorganization.
 
     On March 31, 1994, all of the assets and liabilities of Alanex were
transferred to the Company and Alanex was dissolved.
 
  Principles of Consolidation
 
     The consolidated financial statements include the accounts of Alanex
Corporation and its wholly owned subsidiary Plictrix. All significant
intercompany balances have been eliminated in consolidation.
 
  Debt Securities Available for Sale
 
     In May 1993, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 115, "Accounting for Certain Investments in
Debt and Equity Securities" (SFAS 115). SFAS 115 requires that investments be
classified as "held to maturity," "available for sale" or "trading securities."
Investments held to maturity would be reported at amortized cost. Other
investments in debt and equity securities would be recorded at fair market
value. The Company adopted SFAS 115 effective January 1, 1994. The adoption of
SFAS 115 did not have a material impact on the Company's financial position or
results of operations.
 
     Management determines the appropriate classification of its investments in
debt and equity securities at the time of purchase and reevaluates such
determination at each balance sheet date. Debt securities for which the Company
does not have the intent or ability to hold to maturity are classified as
available for sale. As of December 31, 1994 and 1995 and June 30, 1996, debt
securities available for sale consisted of government-backed and corporate debt
instruments. Debt securities available for sale are carried at fair value, which
approximates cost, with any unrealized gains and losses, net of tax, reported as
a separate component of stockholders' equity. These securities mature at various
dates through 1996.
 
  Inventory
 
     Inventory consists of chemical materials and supplies and is stated at the
lower of cost or net realizable value. Cost is determined on a first-in,
first-out basis.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
       DECEMBER 31, 1994 AND 1995 (AUDITED) AND JUNE 30, 1996 (UNAUDITED)
 
  Depreciation and Amortization
 
     Depreciation and amortization are computed using the double declining
balance method over the estimated useful lives of the related assets or over the
terms of the related capital leases, whichever is shorter (three to fifteen
years). Renewals and replacements which extend the useful life of the asset are
capitalized.
 
  Contract Revenue
 
     Contract research revenue is based on an established rate for each
full-time equivalent scientist ("FTE") and is negotiated to include a reasonable
profit. Research revenue is recognized at the time research and development
activities are performed under the terms of the research contracts. Contract
research payments are generally received in advance of the performance of the
related research activities under the contract at the beginning of each quarter.
Such payments received in excess of amounts earned are recorded as deferred
contract research revenue. Project initiation fees and milestone payments are
nonrefundable and the contracts do not specify any future performance
obligations on the part of the Company related to such fees or payments. Project
initiation fees are recognized under the contract as revenue when earned,
generally when received, upon signing of a contract. Revenue from milestone
payments will be recognized if and when the results or events stipulated in the
agreement have been achieved. Through June 30, 1996, the Company has not
received any milestone payments under any of its collaboration agreements.
 
  Research and Development Costs
 
     All research and development costs are expensed in the period incurred.
 
  Net Income (Loss) Per Share
 
     Net income (loss) per share is computed based upon the weighted average
number of common and common equivalent shares (using the treasury stock method)
outstanding after certain adjustments described below. Common equivalent shares
are not included in the per-share calculations where the effect of their
inclusion would be anti-dilutive, except that, in accordance with Securities and
Exchange Commission Staff Accounting Bulletin No. 83, all common and common
equivalent shares issued during the twelve-month period prior to the initial
filing of the Company's proposed initial public offering have been included in
the calculation as if they were outstanding for all periods presented using the
treasury stock method and the anticipated public offering price of common stock.
 
  Income Taxes
 
     The Company provides for income taxes in accordance with Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" (SFAS
109). Under the asset and liability method of SFAS 109, deferred tax assets and
liabilities are recognized for the future tax consequences attributable to
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax bases. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. Under SFAS 109, the effect on deferred tax assets and
liabilities of a change in tax rates is recognized in operations in the period
that includes the enactment date.
 
  Use of Estimates
 
     The preparation of these consolidated financial statements in conformity
with generally accepted accounting principles requires management of the Company
to make estimates and assumptions that affect
 
                                       F-9

       DECEMBER 31, 1994 AND 1995 (AUDITED) AND JUNE 30, 1996 (UNAUDITED)
 
the reported amounts of assets and liabilities, revenue and expenses, and the
disclosure of contingent assets and liabilities. Actual results could differ
from those estimates.
 
  Consolidated Interim Financial Information
 
     The accompanying interim financial information as of June 30, 1996, and for
the six-month periods ended June 30, 1995 and 1996, is unaudited and, in the
opinion of management, reflects all adjustments that are necessary for a fair
presentation of the Company's financial position, results of operations and cash
flows for the period then ended. All such adjustments are of a normal and
recurring nature.
 
(2) FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     Statement of Financial Accounting Standards No. 107, "Disclosures About
Fair Value of Financial Instruments," requires that fair values be disclosed for
the Company's financial instruments. The carrying amount of cash, other current
assets, accounts payable and accrued expenses, and deferred contract research
revenue are considered to be representative of their respective fair values due
to the short-term nature of those instruments. Debt securities available for
sale are carried at fair value. The carrying amount of the line of credit and
longterm debt are reasonable estimates of their fair values as the debt bears
interest based on market rates currently available for debt with similar terms.
 
(3) RELATED PARTY TRANSACTION
 
     As of December 31, 1995, the Company had a short-term receivable from an
officer of the Company of $10,000, due October 6, 1996. As of May 22, 1996, this
amount was combined with an outstanding note receivable from the officer in the
amount of $50,000 dated January 22, 1996. The new note, in the amount of
$60,000, is due in May 1999 with interest payable annually at the minimum rate
of interest required to avoid imputed interest (6.75% at December 31, 1995).
 
     As of December 31, 1995, the Company also has two notes receivable from
another officer with original principal face values of $17,500 and $50,000. The
balance on the first note of $12,000 is related to the purchase of common stock,
is secured by the stock and is due November 22, 1996. The unsecured note in the
amount of $50,000 is due November 3, 1998. Interest is payable annually at the
minimum rate of interest required to avoid imputed interest (6.75% at December
31, 1995).

     In connection with the secured term note payable, the Company has an
available line of credit for the difference between the balance outstanding on
the term notes and $1,200,000 and $960,000 at December 31, 1994 and 1995,
respectively. The credit facility requires $240,000 of the loan principal
balance to be converted to a term loan and paid annually. The line of credit
bears interest at the 30-day commercial paper rate plus 2.95%. The balance
outstanding on this line of credit was $506,000, $725,000 and $715,000 at
December 31, 1994 and 1995 and June 30, 1996, respectively. Both the term note
payable and line of credit are secured by all of the assets of the Company and
are guaranteed by Amgen Inc. ("Amgen") (Note 7).

(6) RESEARCH AND LICENSE AGREEMENTS
 
  Amgen
 
     In April 1994, the Company and Amgen, a preferred stockholder, entered into
a collaborative research and license agreement to conduct drug research
programs. Under the terms of the agreement, the Company received a negotiated
amount for each research FTE devoted to the programs per year. This research
agreement was terminated by mutual agreement effective in June 1996. Included in
contract revenue for 1994 and 1995 is $1,440,000 and $2,565,000, respectively,
recognized under this agreement (Note 7).
 
  Astra Pharma
 
     In December 1994, the Company and Astra AB entered into a three-year
collaboration agreement for the identification and optimization of lead
compounds that interact with a specific opiate receptor which may have
application in the treatment of pain. The agreement was subsequently assigned to
Astra Pharma, an affiliate of Astra AB. The Company was paid a project
initiation fee of $250,000 and, Astra Pharma is obligated to make additional
payments upon the achievement of certain milestones. In addition, Astra Pharma
is obligated to provide up to $2.25 million of additional funding to support
research undertaken in connection with the agreement. Through June 30, 1996,
Alanex has received $1.3 million under the collaboration agreement. Under the

periods presented to reflect a par value of $0.001 per share.
 
     The Company's 1996 Equity Incentive Plan (the "1996 Plan"), covering an
aggregate of 500,000 shares of Common Stock, was adopted by the Board, subject
to stockholder approval, in July 1996.
 
     In July 1996, the Board adopted, subject to stockholder approval, the
Employee Stock Purchase Plan (the "Purchase Plan") covering an aggregate of
125,000 shares of Common Stock. The Purchase Plan is intended to qualify as an
employee stock purchase plan within the meaning of Section 423(b) of the Code.
Under the Purchase Plan, the Board may authorize participation by eligible
employees, including officers, in periodic offerings of up to 27 months in
length. The Purchase Plan provides that the Board shall specify certain terms
and conditions that will apply to each such offering within the parameters set
forth in the Purchase Plan.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 145 of the Delaware General Corporation Law permits a corporation
to indemnify its directors, officers, employees and other agents in terms
sufficiently broad to permit indemnification (including reimbursement for
expenses) under certain circumstances for liabilities arising under the
Securities Act of 1933, as amended (the "Act"). The Registrant's Bylaws contain
provisions covering indemnification of corporate directors, officers and other
agents against certain liabilities and expenses incurred as a result of
proceedings involving such persons in their capacities as directors, officers,
employees or agents, including proceedings under the Act or the Securities
Exchange Act of 1934.
 
     The Registrant's Bylaws provide for the indemnification of directors and
executive officers to the fullest extent not prohibited by the Delaware General
Corporation Law and authorize the indemnification by the Company of other
officers, employees and other agents as set forth in the Delaware General
Corporation Law. The Registrant has entered into indemnification agreements with
its directors and executive officers, in addition to indemnification provided
for in the Registrant's Bylaws.
 
     The Underwriting Agreement filed as Exhibit 1.1 to this Registration
Statement provides for indemnification by the Underwriters of the Registrant and
its officers and directors for certain liabilities arising under the Act or
otherwise.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
     Since November 19, 1993, the date of the Registrant's inception, the
Registrant has sold and issued (without payment of any selling commission to any
person) the following unregistered securities:
 
          1. During the period November 19, 1993 to September 1, 1996, the
     Registrant granted incentive and non-statutory stock options to employees,
     officers and directors of and consultants to the Company under its 1993
     Stock Plan (the "1993 Plan") covering an aggregate of 914,200 shares of the
     Company's Common Stock. Certain of these option vest over a period of time
     following their respective dates of grant.
 
          2. During the period November 19, 1993 to September 1, 1996, the
     Registrant granted non-statutory stock options to employees, officers,
     directors and consultants of the Company outside of the Company's employee
     benefit plans covering an aggregate of 210,000 shares of the Company's
     Common Stock. Certain of these options vest over a period of time following
     their respective dates of grant.
 
                                      II-1
<PAGE>   70
 
          3. In November 1993, the Registrant issued 350,000 shares of Common
     Stock to a certain executive officer for a promissory note in the amount of
     $17,500 bearing interest at the rate of 6.75% per annum.
 
          4. In November 1993, the Registrant issued 3,640,000 shares of the
     Company's Common Stock to certain founders of the Company in exchange for
     certain partnership interests held by such founders in Alanex, L.P., a
     California limited partnership and certain equity interests in Plictrix,
     Inc., a California corporation.
 
          5. In December 1993, the Registrant issued 140,000 shares of Common
     Stock to a director of the Company for a total purchase price of $1,400.
 
          6. In April 1994, pursuant to the terms of an equity financing of the
     Company, the Registrant issued 2,978,182 shares of the Company's Series A
     Preferred Stock for $4,497,055 in cash to a certain investor. In connection
     with the equity financing, the Registrant granted a warrant to purchase
     703,636 shares of the Company's Common Stock at a purchase price of $.005
     per share to the same investor.
 
          7. In June 1996, the Registrant canceled the warrant referenced in
     paragraph (4) above and granted a warrant to purchase 450,000 shares of the
     Company's Common Stock at a purchase price of $1.51 per share to the same
     investor.
 
     The sales and issuances of securities in the transactions described in
paragraphs (1) and (2), (3) and (5) above were deemed to be exempt from
registration under the Securities Act by virtue of Rule 701 promulgated
thereunder in that they were offered and sold either pursuant to written
compensatory benefit plans or pursuant to a written contract relating to
compensation, as provided by Rule 701.
 
     The sales and issuances of securities in the transactions described in
paragraphs (4), (6) and (7) above were deemed to be exempt from registration
under the Securities Act by virtue of Section 4(2) and/or Regulation D
promulgated thereunder.
 
     The recipients represented their intention to acquire the securities for
investment purposes only and not with a view to the distribution thereof.
Appropriate legends are affixed to the stock certificates issued in such
transactions. Similar legends were imposed in connection with any subsequent
sales of any such securities. All recipients either received adequate
information about the Registrant or had access, through employment or other
relationships, to such information.

ITEM 17. UNDERTAKINGS.
 
     The Registrant hereby undertakes to provide the Underwriters at the closing
specified in the Underwriting Agreement certificates in such denominations and
registered in such names as required by the Underwriters to permit prompt
delivery to each purchaser.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers, and controlling persons of the
Registrant, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Securities Act and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer,
or controlling person of the Registrant in the successful defense of any action,
suit, or proceeding) is asserted by such director, officer, or controlling
person in connection with the securities being registered, the Registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
 
     The undersigned Registrant undertakes that: (1) for purposes of determining
any liability under the Securities Act, the information omitted from the form of
prospectus as filed as part of the registration statement in reliance upon Rule
430A and contained in the form of prospectus filed by the Registrant pursuant to
Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be
part of this registration statement as of the time it was declared effective,
and (2) for the purpose of determining any liability under the Securities Act,
each post-effective amendment that contains a form of prospectus shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

                             UNDERWRITING AGREEMENT


                                                                October __, 1996


PAINEWEBBER INCORPORATED
NEEDHAM & COMPANY, INC.
SUTRO & CO. INCORPORATED
  As Representatives of the
  several Underwriters
c/o PaineWebber Incorporated
  1285 Avenue of the Americas
  New York, New York 10019

Dear Sirs:

                 Alanex Corporation, a Delaware corporation (the "Company"),
proposes to sell an aggregate of 2,500,000 shares (the "Firm Shares") of the
Company's Common Stock, par value $0.001 per share (the "Common Stock"), to you
and to the other underwriters named in Schedule I (collectively, the
"Underwriters"), for whom you are acting as representatives (the
"Representatives").  The Company has also agreed to grant to you and the other
Underwriters an option (the "Option") to purchase up to an additional 375,000
shares of Common Stock (the "Option Shares") on the terms and for the purposes
set forth in Section 1(b).  The Firm Shares and the Option Shares are
hereinafter collectively referred to as the "Shares."

                 The initial public offering price per share for the Shares and
the purchase price per share for the Shares to be paid by the several
Underwriters shall be agreed upon by the Company and the Representatives,
acting on behalf of the several Underwriters, and such agreement shall be set
forth in a separate written instrument substantially in the form of Exhibit A
hereto (the "Price Determination Agreement").  The Price Determination
Agreement may take the form of an exchange of any standard form of written
telecommunication among the Company and the Representatives and shall specify
such applicable information as is indicated in Exhibit A hereto.  The offering
of the Shares will be governed by this Agreement, as supplemented by the Price
Determination Agreement.  From and after the date of the execution and delivery
of the Price Determination Agreement, this
<PAGE>   2
                                       2


Agreement shall be deemed to incorporate, and, unless the context otherwise
indicates, all references contained herein to "this Agreement" and to the
phrase "herein" shall be deemed to include the Price Determination Agreement.

                 Prior to the execution of this Agreement, Alanex Corporation,
a California corporation ("Alanex California"), was merged with and into the
Company (such transaction being referred to herein as the "Merger"), pursuant
to a Merger Agreement in substantially the form of Exhibit 2.1 to the
Registration Statement (the "Merger Agreement").

                 The Company confirms as follows its agreements with the
Representatives and the several other Underwriters.

                 1.       Agreement to Sell and Purchase.

                          (a)     On the basis of the representations,
warranties and agreements of the Company herein contained and subject to all
the terms and conditions of this Agreement, the Company agrees to sell to each
Underwriter named below, and each Underwriter, severally and not jointly,
agrees to purchase from the Company at the purchase price per share for the
Firm Shares to be agreed upon by the Representatives and the Company in
accordance with Section 1(c) and set forth in the Price Determination
Agreement, the number of Firm Shares set forth opposite the name of such
Underwriter in Schedule I, plus such additional number of Firm Shares which
such Underwriter may become obligated to purchase pursuant to Section 8 hereof.
Schedule I may be attached to the Price Determination Agreement.

                          (b)     Subject to all the terms and conditions of
this Agreement, the Company grants the Option to the several Underwriters to
purchase, severally and not jointly, up to 375,000 Option Shares from the
Company at the same price per share as the Underwriters shall pay for the Firm
Shares.  The Option may be exercised only to cover over-allotments in the sale
of the Firm Shares by the Underwriters and may be exercised in whole or in part
at any time (but not more than once) on or before the 30th day after the date
of this Agreement (or, if the Company has elected to rely on Rule 430A, on or
before the 30th day after the date of the Price Determination Agreement), upon
written or telegraphic notice (the "Option Shares Notice") by the
Representatives to the Company no later than 12:00 noon, New York City time, at
least two and no more than five business days before the date specified for
closing in the Option Shares Notice (the "Option Closing Date") setting forth
the aggregate number of Option Shares to be purchased and the time and date for
such purchase.  On the Option Closing Date, the Company will issue and sell to
the Underwriters the number of Option Shares set forth in the Option Shares
Notice, and each Underwriter will purchase such percentage of the Option Shares
as is equal to the percentage of Firm Shares that such Underwriter is
purchasing, as adjusted by the Representatives in such manner as they deem
advisable to avoid fractional shares.

                                       3


                          (c)     The initial public offering price per share
for the Firm Shares and the purchase price per share for the Firm Shares to be
paid by the several Underwriters shall be agreed upon and set forth in the
Price Determination Agreement.  In the event such price has not been agreed
upon and the Price Determination Agreement has not been executed by the close
of business on the fourteenth business day following the date on which the
Registration Statement becomes effective, this Agreement shall terminate
forthwith, without liability of any party to any other party except that
Section 6 shall remain in effect.

                 2.       Delivery and Payment.  Delivery of the Firm Shares
shall be made to the Representatives for the accounts of the Underwriters
against payment of the purchase price by, at the option of the Company, wire
transfer or certified or official bank check payable in New York Clearing House
(same-day) funds to the order of the Company at the office of PaineWebber
Incorporated, 1285 Avenue of the Americas, New York, New York 10019.  Such
payments shall be made at 10:00 a.m., New York City time, on the third business
day (or fourth business day, if the Price Determination Agreement is executed
after 4:30 p.m.) after the date on which the first bona fide offering of the
Shares to the public is made by the Underwriters or at such time on such other
date, not later than ten business days after such date, as may be agreed upon
by the Company and the Representatives (such date is hereinafter referred to as
the "Closing Date").

                          (a)     To the extent the Option is exercised,
delivery of the Option Shares against payment by the Underwriters (in the
manner specified above) will take place at the offices specified above for the
Closing Date at the time and date (which may be the Closing Date) specified in
the Option Shares Notice.

                          (b)     Certificates evidencing the Shares shall be
in definitive form and shall be registered in such names and in such
denominations as the Representatives shall request at least two business days
prior to the Closing Date or the Option Closing Date, as the case may be, by
written notice to the Company.  For the purpose of expediting the checking and
packaging of certificates for the Shares, the Company agrees to make such
certificates available for inspection at least 24 hours prior to the Closing
Date or the Option Closing Date, as the case may be.

                          (c)     The cost of original issue tax stamps, if
any, in connection with the issuance and delivery of the Firm Shares and Option
Shares by the Company to the respective Underwriters shall be borne by the
Company.  The Company will pay and save each Underwriter and any subsequent
holder of the Shares harmless from any and all liabilities with respect to or
resulting from any failure or delay in paying Federal and state stamp and other
transfer taxes, if any, which may be payable or determined to be payable in
connection with the original issuance or sale to such Underwriter of the Firm
Shares and Option Shares.

                 3.       Representations and Warranties of the Company.  The
Company represents, warrants and covenants to each Underwriter that:

                          (a)     A registration statement (Registration No.
333-09929) on Form S-1 relating to the Shares, including a preliminary
prospectus and such amendments to such registration statement as may have been
required to the date of this Agreement, has been prepared by the Company under
the provisions of the Securities Act of 1933, as amended (the "Act"), and the
rules and regulations (collectively referred to as the "Rules and Regulations")
of the Securities and Exchange Commission (the "Commission") thereunder, and
has been filed with the Commission.  The term "preliminary prospectus" as used
herein means a preliminary prospectus as contemplated by Rule 430 or Rule 430A
("Rule 430A") of the Rules and Regulations included at any time as part of the
registration statement.  Copies of such registration statement and amendments
and of each related preliminary prospectus have been delivered to the
Representatives.  The term "Registration Statement" means the registration
statement as amended at the time it becomes or became effective (the "Effective
Date"), including financial statements and all exhibits and any information
deemed to be included by Rule 430A or Rule 434 of the Rules and Regulations.
If the Company files a registration statement to register a portion of the
Shares and relies on Rule 462(b) of the Rules and Regulations for such
registration statement to become effective upon filing with the Commission (the
"Rule 462 Registration Statement"), then any reference to the "Registration
Statement" shall be deemed to include the Rule 462 Registration Statement, as
amended from time to time.  The term "Prospectus" means the prospectus as first
filed with the  Commission pursuant to Rule 424(b) of the Rules and Regulations
or, if no such filing is required, the form of final prospectus included in the
Registration Statement at the Effective Date.

                          (b)     On the Effective Date, the date the
Prospectus is first filed with the Commission pursuant to Rule 424(b) (if
required), at all times subsequent to and including the Closing Date and, if
later, the Option Closing Date and when any post-effective amendment to the
Registration Statement becomes effective or any amendment or supplement to the
Prospectus is filed with the Commission, the Registration Statement and the
Prospectus (as amended or as supplemented if the Company shall have filed with
the Commission any amendment or supplement thereto), including the financial
statements included in the Prospectus, did or will comply with all applicable
provisions of the Act and the Rules and Regulations and will contain all
statements required to be stated therein in accordance with the Act and the
Rules and Regulations.  On the Effective Date and when any post-effective
amendment to the Registration Statement becomes effective, no part of the
Registration Statement or any such amendment did or will contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements therein not
misleading.  At the Effective Date, the date the Prospectus or any amendment or
supplement to the Prospectus is filed with the Commission and at the Closing
Date and, if later, the Option Closing Date, the Prospectus did not or will not
contain any
<PAGE>   5
                                       5

untrue statement of a material fact or omit to state a material fact necessary
to make the statements therein, in the light of the circumstances under which
they were made, not misleading.  The foregoing representations and warranties
in this Section 3(b) do not apply to any statements or omissions made in
reliance on and in conformity with information relating to any Underwriter
furnished in writing to the Company by the Representatives specifically for
inclusion in the Registration Statement or Prospectus or any amendment or
supplement thereto.  For all purposes of this Agreement, the amounts of the
selling concession and reallowance set forth in the Prospectus constitute the
only information relating to any Underwriter furnished in writing to the
Company by the Representatives specifically for inclusion in the Registration
Statement, the preliminary prospectus or the Prospectus.  The Company has not
distributed any offering material in connection with the offering or sale of
the Shares other than the Registration Statement, the preliminary prospectus,
the Prospectus or any other materials, if any, permitted by the Act and the
Rules and Regulations.

                          (c)     The Company is, and at the Closing Date will
be, a corporation duly organized, validly existing and in good standing under
the laws of its jurisdiction of incorporation.  The Company has, and at the
Closing Date will have, full corporate power and authority to conduct all the
activities conducted by it, to own or lease all the assets owned or leased by
it and to conduct its business as described in the Registration Statement and
the Prospectus.  The Company is, and at the Closing Date will be, duly licensed
or qualified to do business and in good standing as a foreign corporation in
all jurisdictions in which the nature of the activities conducted by it or the
character of the assets owned or leased by it makes such licensing or
qualification necessary, except where any failure to be so licensed or
qualified would not, individually or in the aggregate, have a material adverse
effect on the Company or its business, properties, business prospects,
financial condition or results of operations, taken as a whole (a "Material
Adverse Effect").  Except as disclosed in the Registration Statement, the
Company does not own, and at the Closing Date will not own, directly or
indirectly, any shares of stock or any other equity or long-term debt
securities of any corporation or have any equity interest in any firm,
partnership, joint venture, association or other entity.  Complete and correct
copies of the certificate of incorporation and of the by-laws of the Company
and all amendments thereto have been delivered to the Representatives, and no
changes therein will be made subsequent to the date hereof and prior to the
Closing Date or, if later, the Option Closing Date.

                          (d)     The outstanding shares of Common Stock have
been, and the Shares to be issued and sold by the Company upon such issuance
will be, duly authorized, validly issued, fully paid and nonassessable and are
not, and will not be, subject to any preemptive or similar right.  The
description of the Common Stock in the Registration Statement and the
Prospectus is, and at the Closing Date will be, accurate in all material
respects and fairly summarizes the information presented.  Except as set forth
in the Prospectus, the Company does not have outstanding, and at the Closing
Date will not have outstanding, any options to purchase, or any rights or
warrants to subscribe for, or any
<PAGE>   6
                                       6

securities or obligations convertible into, or any contracts or commitments to
issue or sell, any shares of Common Stock or any such warrants, convertible
securities or obligations.

                          (e)     The financial statements and schedules
included in the Registration Statement or the Prospectus present fairly the
financial condition of the Company as of the respective dates thereof and the
results of operations and cash flows of the Company for the respective periods
covered thereby, all in conformity with generally accepted accounting
principles applied on a consistent basis throughout the entire period involved,
except as otherwise disclosed in the Prospectus.  No other financial statements
or schedules of the Company are required by the Act or the Rules and
Regulations to be included in the Registration Statement or the Prospectus.
KPMG Peat Marwick LLP (the "Accountants") who have reported on such financial
statements and schedules, are independent accountants with respect to the
Company as required by the Act and the Rules and Regulations.

                          (f)     The Company maintains a system of internal
accounting controls sufficient to provide reasonable assurance that (i)
transactions are executed in accordance with management's general or specific
authorization; (ii) transactions are recorded as necessary to permit
preparation of financial statements in conformity with generally accepted
accounting principles and to maintain accountability for assets; (iii) access
to assets is permitted only in accordance with management's general or specific
authorization; and (iv) the recorded accountability for assets is compared with
existing assets at reasonable intervals and appropriate action is taken with
respect to any differences.

                          (g)     Subsequent to the respective dates as of which
information is  given in the Registration Statement and the Prospectus and prior
to the Closing Date, except as set forth in or contemplated by the Registration
Statement and the Prospectus (including (i) the granting of stock options
pursuant to the Company's 1996 Equity Incentive Plan, (ii) the exercise of
employee stock options outstanding on the date hereof and (iii) the offering of
shares of Common Stock pursuant to the Company's Employee Stock Purchase Plan),
(i) there has not been and will not have been any change in the capitalization
of the Company, (ii) the Company has not incurred nor will it incur any material
liabilities or obligations, direct or contingent, nor has it entered into nor
will it enter into any material transactions other than pursuant to this
Agreement and the transactions referred to herein and (iii) the Company has not
and will not have paid or declared any dividends or other distributions of any
kind on any class of its capital stock.

                          (h)     The Company is not, and after giving effect
to the offering and sale of the Shares and the application of the proceeds
thereof as described in the Registration Statement and Prospectus will not be,
an "investment company" or an "affiliated person" of, or "promoter" or
"principal underwriter" for, an "investment company," as such terms are defined
in the Investment Company Act of 1940, as amended.
<PAGE>   7
                                       7

                          (i)     Except as set forth in the Registration
Statement and the Prospectus, there are no actions, suits or proceedings
pending or, to the best knowledge of the Company, threatened against or
affecting the Company or any of its officers in their capacity as such, before
or by any Federal or state court, commission, regulatory body, administrative
agency or other governmental body, domestic or foreign, wherein an unfavorable
ruling, decision or finding would reasonably be expected to have a Material
Adverse Effect.

                          (j)     The Company has, and at the Closing Date will
have, (i) all governmental licenses, permits, consents, orders, approvals and
other authorizations necessary to carry on its business as contemplated in the
Prospectus, (ii) complied in all respects with all laws, regulations and orders
applicable to it or its business and (iii) performed all its obligations
required to be performed by it, and is not, and at the Closing Date will not
be, in default, under any indenture, mortgage, deed of trust, voting trust
agreement, loan agreement, bond, debenture, note agreement, lease, contract or
other agreement or instrument (collectively, a "contract or other agreement")
to which it is a party or by which its property is bound or affected, except,
in each case, where the failure to have such license, permit, consent, order,
approval or other authorization, or the failure to comply or perform or where
such default would not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect.  To the best knowledge of the
Company, no other party under any material contract or other agreement to which

provisions of, or result in a breach or violation of any of the terms or
provisions of, or constitute a default under, or give any other party a right

court or other governmental agency or body applicable to the business or
properties of the Company, except, in each case, where such lien, charge,
encumbrance, breach, violation, default, termination, acceleration, or conflict
would not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect.

properties and assets described in the Prospectus as owned by it, free and

by the Company in this Agreement or made in any certificate or document
required by this Agreement to be delivered to the Representatives was or will
be, when made, inaccurate, untrue or incorrect in any material respect (except

such term).

such infringement of or conflict with) asserted rights of others with respect

The Company is in compliance with the Environmental Laws in all material
respects, and there is no pending or, to the Company's knowledge, threatened,
action or proceeding against the Company alleging violations of the
Environmental Laws.

full corporate power and authority to enter into the Merger Agreement and to
consummate the Merger.  The Merger Agreement was duly authorized, executed and
delivered by each of the Company and Alanex California and constituted a valid

except as enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, arrangement, moratorium or other similar laws affecting
creditors' rights, and subject to general equity principles and to limitations
on availability of equitable relief.  The performance of the Merger Agreement
and the consummation of Merger and other transactions contemplated thereby did
not result in the creation or imposition of any lien, charge or encumbrance
upon any of the assets of either the Company or Alanex California pursuant to
the terms or provisions of, or result in a breach or violation of any of the

applicable to the business or properties of the Company or Alanex California
except, in each case, where such lien, charge, encumbrance, breach, violation,

the Merger Agreement without waiver or modification of its terms unless any
such waiver or modification was approved in writing by the Representatives, and
such Merger is effective under applicable law with the effects set forth in
Section 259 of the Delaware General Corporation Law.  All consents and
approvals to the Merger, including any necessary regulatory approvals required
for the Company to conduct its business in the same manner as the business of
Alanex California immediately prior to the Merger, have been obtained, except
where the failure to obtain such consent or approval would not have a Material
Adverse Effect; and all actions by or in respect of or filing with any
governmental body, agency, official or authority required to consummate or

dealer, file any amendment or supplement to the Registration Statement or the

the happening of any event during the period mentioned in the second sentence
of Section 4(e) that in the judgment of the Company makes any statement made in
the Registration Statement or the Prospectus untrue or that requires the making
of any changes in the Registration Statement or the Prospectus in order to make
the statements therein, in light of the circumstances in which they are made,
not misleading and (5) of receipt by the Company, its counsel or auditors or

Commission shall issue any order suspending the effectiveness of the
Registration Statement, the Company will make every reasonable effort to obtain
the withdrawal of such order at the earliest possible moment.  The Company will
use its best efforts to comply with the provisions of and make all requisite

of the Prospectus or any amendment or supplement thereto by the several
Underwriters and by all dealers to whom the Shares may be sold, both in
connection with the offering or sale of the Shares and for any period of time
thereafter during which the Prospectus is required by law to be delivered in
connection therewith.  If during such period of time any event shall occur which
in the judgment of the Company or counsel to the Underwriters should be set
forth in the Prospectus in order to make any statement therein, in the light of
the circumstances under which it was made, not misleading, or if it is necessary
to supplement or amend the Prospectus to comply with law, the Company will
forthwith prepare and duly file with the Commission an appropriate supplement or
amendment thereto, and will deliver to each of the Underwriters, without charge,
such number of copies thereof as the Representatives may reasonably request.

not be audited but shall be in reasonable detail) for a period of 12 months
ended commencing after the Effective Date, and satisfying the provisions of
Section 11(a) of the Act (including Rule 158 of the Rules and Regulations).

offering and sale of the Shares by the Underwriters or by dealers to whom
Shares may be sold, (5) the listing and quotation of the Shares on the Nasdaq
National Market, (6) any filings required to be made by the Underwriters with
the NASD, and the reasonable fees, disbursements and other charges of counsel
for the Underwriters in connection therewith, (7) the registration or
qualification of the Shares for offer and sale under the securities or Blue Sky
laws of such jurisdictions designated pursuant to Section 4(f), including the
reasonable fees, disbursements and other charges of counsel to the Underwriters
in connection therewith, and the preparation and printing of preliminary,
supplemental and final Blue Sky memoranda, (8) counsel to the Company, (9) the

the Company pursuant to any of the provisions hereof (otherwise than pursuant
to Section 8) or (ii) by the Underwriters pursuant to Section 5 (other than a
termination resulting solely from a failure to satisfy the conditions listed in
paragraph (h) or (n) of Section 5), Section 7(a) or Section 7(b)(i), the
Company will reimburse the several Underwriters for all out-of-pocket expenses
(including the fees, disbursements and other charges of counsel to the

         make the statements therein, in light of the circumstances under which
         they were made, not misleading and (B) since the Effective Date, no
         event has occurred as a result of which it is necessary to amend or
         supplement the Prospectus in order to make the statements therein not
         untrue or misleading in any material respect.

                                  (ii)     Each of the representations and
         warranties of the Company contained in this Agreement were, when
         originally made, and are, at the time such certificate is delivered,
         true and correct in all material respects (except that such phrase "in
         all material respects" shall be disregarded to the extent any such
         representation and warranty is qualified by "material", "material
         adverse change", "Material Adverse Effect" or any phrase using any
         such term).

                                  (iii)    Each of the covenants required
         herein to be performed by the Company on or prior to the delivery of
         such certificate has been duly, timely and fully performed and each
         condition herein required to be complied with by the Company on or
         prior to the date of such certificate has been duly, timely and fully
         complied with.

                                  (iv)     A Material Adverse Change has not
         occurred.

                          (k)     On or prior to the Closing Date, the
Representatives shall have received the executed agreements referred to in
Section 4(n).

                          (l)     The Shares shall be qualified for sale in
such states as the Representatives may reasonably request, each such
qualification shall be in effect and not subject to any stop order or other
proceeding on the Closing Date and the Option Closing Date.

                          (m)     Prior to the Closing Date, the Shares shall
have been qualified for quotation on the Nasdaq National Market, subject only
to notice of official issuance.

                          (n)     The NASD shall not have raised any objection
with respect to the fairness and reasonableness of the underwriting terms and
arrangements that has not been resolved to the NASD's satisfaction.

                          (o)     The Company shall have furnished to the
Representatives such certificates, in addition to those specifically mentioned
herein, as the Representatives may have reasonably requested as to the accuracy
and completeness at the Closing Date and the Option Closing Date of any
statement in the Registration Statement or the Prospectus as to the accuracy at
the Closing Date and the Option Closing Date of the representations and
warranties of the Company herein, as to the performance by the Company of its
obligations
<PAGE>   18
                                       18

hereunder, or as to the fulfillment of the conditions concurrent and precedent
to the obligations hereunder of the Representatives.

                 If any of the conditions specified in this Section 5 shall not
have been fulfilled when and as required by this Agreement, this Agreement may
be terminated by you on notice to the Company at any time at or prior to the
Closing Time, and such termination shall be without liability of any party to
any other party except as provided in Section 4(i) and (j) herein.

                 6.       Indemnification.

                          (a)     The Company will indemnify and hold harmless
each Underwriter, the directors, officers, employees and agents of each
Underwriter and each person, if any, who controls each Underwriter within the
meaning of Section 15 of the Act or Section 20 of the Securities Exchange Act
of 1934, as amended (the "Exchange Act") from and against any and all losses,
claims, liabilities, expenses and damages (including any and all investigative,
legal and other expenses reasonably incurred in connection with, and any amount
paid in settlement of, any action, suit or proceeding between any of the
indemnified parties and any indemnifying parties or between any indemnified
party and any third party, or otherwise, or any claim asserted), to which they,
or any of them, may become subject under the Act, the Exchange Act or other
Federal or state statutory law or regulation, at common law or otherwise,
insofar as such losses, claims, liabilities, expenses or damages arise out of
or are based on (i) any untrue statement or alleged untrue statement of a
material fact contained in any preliminary prospectus, the Registration
Statement or the Prospectus or any amendment or supplement to the Registration
Statement or the Prospectus, (ii) the omission or alleged omission to state in
such document a material fact required to be stated in it or necessary to make
the statements in it not misleading or (iii) any act or failure to act or any
alleged act or failure to act by an underwriter in connection with, or relating
in any manner to, the Shares or the offering contemplated hereby, and which is
included as part of or referred to in any loss, claim, damage, liability or
action arising out of or based upon matters covered by clause (i) or (ii) above
(provided that the Company shall not be liable under this clause (iii) to the
extent it is determined in a final judgment by a court of competent
jurisdiction that such loss, claim, damage, liability or action resulted
directly from any such acts or failures to act undertaken or omitted to be
taken by such underwriter through its gross negligence or willful misconduct);
provided that the Company will not be liable to the extent that such loss,
claim, liability, expense or damage (i) arises from the sale of the Shares in
the public offering to any person by an Underwriter and is based on an untrue
statement or omission or alleged untrue statement or omission made in reliance
on and in conformity with information relating to any Underwriter furnished in
writing to the Company by the Representatives on behalf of any Underwriter
expressly for inclusion in the Registration Statement, any preliminary
prospectus or the Prospectus or (ii) results solely from an untrue statement of
a material fact contained in, or the omission of a material fact
<PAGE>   19
                                       19

from, such preliminary prospectus, which untrue statement or omission was
completely corrected in the Prospectus (as then amended or supplemented) if the
Company shall sustain the burden of proving that the Underwriters sold Shares
to the person alleging such loss, claim, liability, expense or damage without
sending or giving, at or prior to the written confirmation of such sale, a copy
of the Prospectus (as then amended or supplemented) if the Company had
previously furnished copies thereof to the Underwriters within a reasonable
amount of time prior to such sale or such confirmation, and the Underwriters
failed to deliver the corrected Prospectus, if required by law to have so
delivered it.  This indemnity agreement will be in addition to any liability
that the Company might otherwise have.

                          (b)     Each Underwriter will indemnify and hold
harmless the Company, each person, if any, who controls the Company within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act, each
director of the Company and each officer of the Company who signs the
Registration Statement to the same extent as the foregoing indemnity from the
Company to each Underwriter, but only insofar as losses, claims, liabilities,
expenses or damages arise out of or are based on any untrue statement or
omission or alleged untrue statement or omission made in reliance on and in
conformity with information relating to any Underwriter furnished in writing to
the Company by the Representatives on behalf of such Underwriter expressly for
use in the Registration Statement, the Preliminary Prospectus or the
Prospectus.  This indemnity will be in addition to any liability that each
Underwriter may otherwise have.

                          (c)     Any party that proposes to assert the right
to be indemnified under this Section 6 will, promptly after receipt of notice
of commencement of any action against such party in respect of which a claim is
to be made against an indemnifying party or parties under this Section 6,
notify each such indemnifying party of the commencement of such action,
enclosing a copy of all papers served, but the omission so to notify such
indemnifying party will not relieve it from any liability that it may have to
any indemnified party under the foregoing provisions of this Section 6 unless,
and only to the extent that, such omission results in the forfeiture of
substantive rights or defenses by the indemnifying party.  If any such action
is brought against any indemnified party and it notifies the indemnifying party
of its commencement, the indemnifying party will be entitled to participate in
and, to the extent that it elects by delivering written notice to the
indemnified party promptly after receiving notice of the commencement of the
action from the indemnified party, jointly with any other indemnifying party
similarly notified, to assume the defense of the action, with counsel
satisfactory to the indemnified party, and after notice from the indemnifying
party to the indemnified party of its election to assume the defense, the
indemnifying party will not be liable to the indemnified party for any legal or
other expenses except as provided below and except for the reasonable costs of
investigation subsequently incurred by the indemnified party in connection with
the defense.  The indemnified party will have the right to employ its own
counsel in any such action, but the fees, expenses and other charges of such
counsel will be at the expense of such indemnified
<PAGE>   20
                                       20

party unless (1) the employment of counsel by the indemnified party has been
authorized in writing by the indemnifying party, (2) the indemnified party has
reasonably concluded (based on advice of counsel) that there may be legal
defenses available to it or other indemnified parties that are different from
or in addition to those available to the indemnifying party, (3) a conflict or
potential conflict exists (based on advice of counsel to the indemnified party)
between the indemnified party and the indemnifying party (in which case the
indemnifying party will not have the right to direct the defense of such action
on behalf of the indemnified party) or (4) the indemnifying party has not in
fact employed counsel to assume the defense of such action within a reasonable
time after receiving notice of the commencement of the action, in each of which
cases the reasonable fees, disbursements and other charges of counsel will be
at the expense of the indemnifying party or parties.  It is understood that the
indemnifying party or parties shall not, in connection with any proceeding or
related proceedings in the same jurisdiction, be liable for the reasonable
fees, disbursements and other charges of more than one separate firm admitted
to practice in such jurisdiction at any one time for all such indemnified party
or parties.  All such fees, disbursements and other charges will be reimbursed
by the indemnifying party promptly as they are incurred.  An indemnifying party
will not be liable for any settlement of any action or claim effected without
its written consent (which consent will not be unreasonably withheld).  No
indemnifying party shall, without the prior written consent of each indemnified
party, settle or compromise or consent to the entry of any judgment in any
pending or threatened claim, action or proceeding relating to the matters
contemplated by this Section 6 (whether or not any indemnified party is a party
thereto) (a "Settlement"), unless such Settlement includes an unconditional
release of each indemnified party from all liability arising or that may arise
out of such claim, action or proceeding.  Notwithstanding any other provision
of this Section 6(c), if at any time an indemnified party shall have requested
an indemnifying party to reimburse the indemnified party for fees and expenses
of counsel, such indemnifying party agrees that it shall be liable for any
Settlement effected without its written consent if (i) such Settlement is
entered into more than 45 days after receipt by such indemnifying party of the
aforesaid request, (ii) such indemnifying party shall have received notice of
the terms of such Settlement at least 30 days prior to such Settlement being
entered into and (iii) such indemnifying party shall not have reimbursed such
indemnified party in accordance with such request prior to the date of such
Settlement.

                          (d)     In order to provide for just and equitable
contribution in circumstances in which the indemnification provided for in the
foregoing paragraphs of this Section 6 is applicable in accordance with its
terms but for any reason is held to be unavailable from the Company or the
Underwriters, the Company and the Underwriters will contribute to the total
losses, claims, liabilities, expenses and damages (including any investigative,
legal and other expenses reasonably incurred in connection with, and any amount
paid in settlement of, any action, suit or proceeding or any claim asserted,
but after deducting any contribution received by the Company from persons other
than the Underwriters, such as persons who control the Company within the
meaning of the Act,
<PAGE>   21
                                       21

officers of the Company who signed the Registration Statement and directors of
the Company, who also may be liable for contribution) to which the Company and
any one or more of the Underwriters may be subject in such proportion as shall
be appropriate to reflect the relative benefits received by the Company on the
one hand and the Underwriters on the other.  The relative benefits received by
the Company on the one hand and the Underwriters on the other shall be deemed
to be in the same proportion as the total net proceeds from the offering
(before deducting expenses) received by the Company bear to the total
underwriting discounts and commissions received by the Underwriters, in each
case as set forth in the table on the cover page of the Prospectus.  If, but
only if, the allocation provided by the foregoing sentence is not permitted by
applicable law, the allocation of contribution shall be made in such proportion
as is appropriate to reflect not only the relative benefits referred to in the
foregoing sentence but also the relative fault of the Company, on the one hand,
and the Underwriters, on the other, with respect to the statements or omissions
which resulted in such loss, claim, liability, expense or damage, or action in
respect thereof, as well as any other relevant equitable considerations with
respect to such offering.  Such relative fault shall be determined by reference
to whether the untrue or alleged untrue statement of a material fact or
omission or alleged omission to state a material fact relates to information
supplied by the Company or the Representatives on behalf of the Underwriters,
the intent of the parties and their relative knowledge, access to information
and opportunity to correct or prevent such statement or omission.  The Company
and the Underwriters agree that it would not be just and equitable if
contributions pursuant to this Section 6(d) were to be determined by pro rata
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take into account
the equitable considerations referred to herein.  The amount paid or payable by
an indemnified party as a result of the loss, claim, liability, expense or
damage, or action in respect thereof, referred to above in this Section 6(d)
shall be deemed to include, for purpose of this Section 6(d), any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim.  Notwithstanding the
provisions of this Section 6(d), no Underwriter shall be required to contribute
any amount in excess of the underwriting discounts received by it and no person
found guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) will be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.  The Underwriters' obligations to
contribute as provided in this Section 6(d) are several in proportion to their
respective underwriting obligations and not joint.  For purposes of this
Section 6(d), any person who controls a party to this Agreement within the
meaning of the Act will have the same rights to contribution as that party, and
each officer of the Company who signed the Registration Statement will have the
same rights to contribution as the Company, subject in each case to the
provisions hereof.  Any party entitled to contribution, promptly after receipt
of notice of commencement of any action against such party in respect of which
a claim for contribution may be made under this Section 6(d), will notify any
such party or parties from whom contribution may be sought, but the omission so
to notify will not relieve the party or parties from whom contribution may be
sought from any other
<PAGE>   22
                                       22

obligation it or they may have under this Section 6(d).  Except for a
Settlement entered into pursuant to the last sentence of Section 6(c), no party
will be liable for contribution with respect to any action or claim settled
without its written consent (which consent will not be unreasonably withheld).

                          (e)     The indemnity and contribution agreements
contained in this Section 6 and the representations and warranties of the
Company contained in this Agreement shall remain operative and in full force
and effect regardless of (i) any investigation made by or on behalf of the
Underwriters, (ii) acceptance of the Shares and payment therefor or (iii) any
termination of this Agreement.

                 7.       Termination.

                          (a)     If the Company shall fail on the Closing Date
or on the Option Closing Date to sell and deliver the Shares or Option Shares
which it is obligated to sell hereunder then the Underwriters may, at their
option, by notice from the Representatives to the Company terminate this
Agreement without any liability on the part of any Underwriter to the Company.

                          (b)     The obligations of the several Underwriters
under this Agreement may be terminated at any time on or prior to the Closing
Date (or, with respect to the Option Shares, on or prior to the Option Closing
Date), by notice to the Company from the Representatives, without liability on
the part of any Underwriter to the Company, if, prior to delivery and payment
for the Shares (or the Option Shares, as the case may be), in the sole judgment
of the Representatives, (i) there has been, since the respective dates as of
which information is given in the Registration Statement, any Material Adverse
Change, (ii) trading in any of the equity securities of the Company shall have
been suspended by the Commission, the NASD, by an exchange that lists the
Shares or by the NASDAQ Stock Market, (iii) trading in securities generally on
the New York Stock Exchange or in the NASDAQ Stock Market shall have been
suspended or limited or minimum or maximum prices shall have been generally
established on such exchange or over-the-counter market, or additional material
governmental restrictions, not in force on the date of this Agreement, shall
have been imposed upon trading in securities generally by such exchange or
over-the-counter market or by order of the Commission or the NASD or any court
or other governmental authority, (iv) a general banking moratorium shall have
been declared by either Federal or New York State authorities or (v) any
material adverse change in the financial or securities markets in the United
States or in political, financial or economic conditions in the United States
or any outbreak or material escalation of hostilities or declaration by the
United States of a national emergency or war or other calamity or crisis shall
have occurred the effect of any of which is such as to make it, in the sole
judgment of the Representatives, impracticable or inadvisable to market the
Shares on the terms and in the manner contemplated by the Prospectus.
<PAGE>   23
                                       23


                 8.       Substitution of Underwriters.  If any one or more of
the Underwriters shall fail or refuse to purchase any of the Firm Shares which
it or they have agreed to purchase hereunder, and the aggregate number of Firm
Shares which such defaulting Underwriter or Underwriters agreed but failed or
refused to purchase is not more than one-tenth of the aggregate number of Firm
Shares, the other Underwriters shall be obligated, severally, to purchase the
Firm Shares which such defaulting Underwriter or Underwriters agreed but failed
or refused to purchase, in the proportions which the number of Firm Shares
which they have respectively agreed to purchase pursuant to Section 1 bears to
the aggregate number of Firm Shares which all such non-defaulting Underwriters
have so agreed to purchase, or in such other proportions as the Representatives
may specify; provided, that in no event shall the maximum number of Firm Shares
which any Underwriter has become obligated to purchase pursuant to Section 1 be
increased pursuant to this Section 8 by more than one-ninth of the number of
Firm Shares agreed to be purchased by such Underwriter without the prior
written consent of such Underwriter.  If any Underwriter or Underwriters shall
fail or refuse to purchase any Firm Shares and the aggregate number of Firm
Shares which such defaulting Underwriter or Underwriters agreed but failed or
refused to purchase exceeds one-tenth of the aggregate number of the Firm
Shares and arrangements satisfactory to the Representatives and the Company for
the purchase of such Firm Shares are not made within 48 hours after such
default, this Agreement will terminate without liability on the part of any
non-defaulting Underwriter or the Company for the purchase or sale of any
Shares under this Agreement.  In any such case either the Representatives or
the Company shall have the right to postpone the Closing Date, but in no event
for longer than seven days, in order that the required changes, if any, in the
Registration Statement and in the Prospectus or in any other documents or
arrangements may be effected.  Any action taken pursuant to this Section 8
shall not relieve any defaulting Underwriter from liability in respect of any
default of such Underwriter under this Agreement.

                 9.       Miscellaneous.  Notice given pursuant to any of the
provisions of this Agreement shall be in writing and, unless otherwise
specified, shall be mailed or delivered (a) if to the Company, at the office of
the Company,  3550 General Atomics Court, San Diego, California 92121,
Attention:  President, or (b) if to the Underwriters, to the Representatives at
the offices of PaineWebber Incorporated, 1285 Avenue of the Americas, New York,
New York 10019, Attention:  Corporate Finance Department.  Any such notice
shall be effective only upon receipt.  Any notice under Section 7 or 8 may be
made by telex or telephone, but if so made shall be subsequently confirmed in
writing.

                 This Agreement has been and is made solely for the benefit of
the several Underwriters and the Company and of the controlling persons,
directors and officers referred to in Section 6, and their respective
successors and assigns, and no other person shall acquire or have any right
under or by virtue of this Agreement.  The term "successors and assigns" as
used in this Agreement shall not include a purchaser, as such purchaser, of
Shares from any of the several Underwriters.
<PAGE>   24
                                       24


                 All representations, warranties and agreements of the Company
contained herein or in certificates or other instruments delivered pursuant
hereto, shall remain operative and in full force and effect regardless of any
investigation made by or on behalf of any Underwriter or any of its controlling
persons and shall survive delivery of and payment for the Shares hereunder.

                 Any action required or permitted to be taken by the
Representatives under this Agreement may be taken by them jointly or by
PaineWebber Incorporated.

                 THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE
CONFLICT OF LAWS PRINCIPLES OF SUCH STATE.

                 This Agreement may be signed in two or more counterparts with
the same effect as if the signatures thereto and hereto were upon the same
instrument.

                  In case any provision in this Agreement shall be invalid,
illegal or unenforceable, the validity, legality and enforceability of the
remaining provisions shall not in any way be affected or impaired thereby.

                 The Company and the Underwriters each hereby irrevocably waive
any right they may have to a trial by jury in respect of any claim based upon
or arising out of this Agreement or the transactions contemplated hereby.

                 This Agreement may not be amended or otherwise modified or any
provision hereof waived except by an instrument in writing signed by the
Representatives and the Company.

agreement among the Company and the several Underwriters.

PAINEWEBBER INCORPORATED
NEEDHAM & COMPANY, INC.
SUTRO & CO. INCORPORATED
  As Representatives of the several Underwriters
c/o PaineWebber Incorporated
1285 Avenue of the Americas
New York, New York 10019

Dear Sirs:

                 Reference is made to the Underwriting Agreement, dated
October ___, 1996 (the "Underwriting Agreement"), among Alanex Corporation, a
Delaware corporation (the "Company"), and the several Underwriters named in
Schedule I thereto or hereto (the "Underwriters"), for whom PaineWebber
Incorporated, Needham & Company, Inc. and Sutro & Co. Incorporated are acting
as representatives (the "Representatives").  The Underwriting Agreement

                               Form of Opinion of
                              Cooley Godward LLP*


                 1.       The Company is a corporation duly organized, validly
existing and in good standing under the laws of the State of Delaware and has
full corporate power and authority to conduct all the activities conducted by
it, to own or lease all the assets and properties owned or leased by it and to
conduct its business as described in the Registration Statement and the
Prospectus.

                 2.       To the best of our knowledge, the Company is duly
qualified to transact business as a foreign corporation and is in good standing
in each state or territory of the United States in which it owns or leases
property of a nature, or transacts business of a type, that would make such
qualification necessary, except to the extent that the failure to so qualify or
be in good standing would not have a Material Adverse Effect.

                 3.       All of the outstanding shares of Common Stock have
been, and the Shares, when paid for by the Underwriters in accordance with the
terms of the Agreement, will be, duly authorized, validly issued, fully paid
and nonassessable.  The Shares are not subject to any preemptive or similar
right under (i) the statutes and judicial and administrative decisions of the
State of Delaware, (ii) the Company's certificate of incorporation or by-laws
or (iii) any instrument, contract or other agreement described in the
Registration Statement or any instrument, document, contract or agreement filed
as an exhibit to the Registration Statement.  Except as described in the
Registration Statement or the Prospectus, to the best of our knowledge, the
Company has no commitment to issue, and the Company has no outstanding options,
warrants or other rights calling for the issuance of, any share of capital
stock of the Company to any person or any security or other instrument that by
its terms is convertible into, exercisable for or exchangeable for capital
stock of the Company.

                 4.       No consent, approval, authorization or order of, or
any filing or declaration with, any court or governmental agency or body is
required in connection with the authorization, issuance, sale or delivery of
the Shares by the Company, in connection with the execution, delivery and
performance of the Agreement by the Company or in





__________________________________

*        All references in this opinion to the Agreement shall include the
         Price Determination Agreement.  Capitalized terms used herein and not
         otherwise defined have the same meanings as in the Underwriting
         Agreement.
<PAGE>   33
                                       2

connection with the taking by the Company of any action contemplated thereby,
except such as have been obtained under the Act and the Rules and Regulations
and such as may be required under state securities or "Blue Sky" laws or by the
by-laws and rules of the NASD in connection with the purchase and distribution
by the Underwriters of the Shares.

                 5.       The authorized, issued and outstanding capital stock
of the Company is as set forth in the Registration Statement and the Prospectus
under the caption "Capitalization" except for issuances of common stock upon
exercise of outstanding options and warrants.  The Shares conform in all
material respects as to legal matters to the description thereof in the
Prospectus under the caption "Description of Capital Stock--Common Stock" and
the statements made under such caption, to the extent they constitute matters
of law or legal conclusions, are accurate in all material respects and fairly
summarize the information presented therein to the extent required by the Act
and the Rules and Regulations.  The form of certificate used to evidence the
Common Stock is in due and proper form and complies with all applicable
statutory requirements of the General Corporation Law of the State of Delaware.

                 6.       The Registration Statement and the Prospectus comply
in all material respects as to form with the requirements of the Act and the
Rules and Regulations (except that we express no opinion as to financial
statements, schedules and other financial data and statistical data derived
therefrom contained in the Registration Statement or the Prospectus).  To the
best of our knowledge, any instrument, document, lease, license, contract or
other agreement to which the Company is a party (collectively, "Documents")
required to be described or referred to in the Registration Statement or the
Prospectus has been described or referred to therein to the extent required by
the Act and the Rules and Regulations and any Document required by the Act and
the Rules and Regulations to be filed as an exhibit to the Registration
Statement has been filed as an exhibit thereto.

                 7.       To the best of our knowledge, except as disclosed in
the Registration Statement or the Prospectus, no person or entity has the right
to require the registration under the Act of shares of Common Stock or other
securities of the Company by reason of the filing or effectiveness of the
Registration Statement.

                 8.       All descriptions in the Prospectus of statutes,
regulations or legal or governmental proceedings contained under the caption
"Shares Eligible for Future Sale" are accurate in all material respects and
fairly summarizes the information presented to the extent required by the Act
and the Rules and Regulations.

                 9.       The Company has full corporate power and authority to
enter into the Agreement, and the Agreement has been duly authorized, executed
and delivered by the Company, is a valid and binding agreement of the Company
and, except for the
<PAGE>   34
                                       3

indemnification and contribution provisions thereof, as to which we express no
opinion, is enforceable against the Company in accordance with the terms
thereof.

                 10.      The execution and delivery by the Company of, and the
performance by the Company of its agreements in, the Agreement do not and will
not (i) violate the certificate of incorporation or by-laws of the Company,
(ii) breach or result in a default under, cause the time for performance of any
obligation to be accelerated under, or result in the creation or imposition of
any lien, charge or encumbrance upon any of the assets of the Company pursuant
to the terms of, any Document filed as an exhibit to the Registration Statement
except, in each case, where such breach, default, acceleration, lien, charge or
encumbrance would not have a Material Adverse Effect, (iii) breach or otherwise
violate any existing obligation of the Company under any court or
administrative order, judgment or decree of which we have knowledge or (iv)
violate applicable provisions of any statute or regulation in the
United States or the Delaware General Corporation Law.

                 11.      The Company is not an "investment company," as such
term is defined in the Investment Company Act of 1940, as amended.

                 12.      The Shares have been duly approved for quotation on
the Nasdaq National Market.

                 13.      The Company and Alanex California had full corporate
power and authority to enter into the Merger Agreement and to consummate the
Merger.  The Merger Agreement was duly authorized, executed and delivered by
each of the Company and Alanex California and constituted a valid and binding
agreement of the Company and Alanex California and was enforceable against the
Company and Alanex California in accordance with the terms thereof.  The
performance of the Merger Agreement and the consummation of Merger did not,
except as would not have a Material Adverse Effect, result in the creation or
imposition of any lien, charge or encumbrance upon any of the assets of either
the Company or Alanex California pursuant to the terms or provisions of, or
result in a breach or violation of any of the terms or provisions of, or
constitute a default under, or give any other party a right to terminate any of
its obligations under, or result in the acceleration of any obligation under,
the respective charters or by-laws of the Company or Alanex California, any
Document filed as an exhibit to the Registration Statement, or violate or
conflict with any judgment, ruling, decree, order, statute, rule or regulation
of any court or other governmental agency or body applicable to the business or
properties of the Company or Alanex California.

                 14.      The Merger was consummated in accordance with the
Merger Agreement without waiver or modification of its terms in any material
respect except to the extent any such waiver or modification has been approved
in writing by the Representatives,
<PAGE>   35
                                       4

and such Merger is effective under applicable law with the effects set forth in
Section 259 of the Delaware General Corporation Law.

                 15.      We have been advised by the Staff of the Commission
that the Registration Statement became effective under the Act on
_____________, 1996 and that, to the best of our knowledge, no order suspending
the effectiveness of the Registration Statement has been issued and no
proceeding for that purpose has been instituted or is pending or threatened.

                 16.      The required filing of the Prospectus pursuant to
Rule 424(b) has been made in the manner and within the time period required by
Rule 424(b).

                 17.      To the best of our knowledge, there are no actions,
suits, proceedings or investigations pending or overtly threatened against the
Company before or by any court, governmental agency or arbitrator which (i)
seek to challenge the legality or enforceability of the Agreement or (ii) are
required to be described in the Prospectus under the Act and the Rules and
Regulations that have not been described as required.

                 In connection with the preparation of the Registration
Statement and the Prospectus, we have participated in conferences with officers
and representatives of the Company and with its certified public accountants
(as you and your counsel have done).  At such conferences we have made
inquiries of such officers, representatives and accountants, and discussed the
contents of the Registration Statement and the Prospectus.  We have not
ourselves independently verified, and accordingly, do not comment upon, the
accuracy, completeness or fairness of the Registration Statement or the
Prospectus.  Based upon the foregoing, nothing has come to our attention that
causes us to believe that, as of the Effective Date, the Registration Statement
[or any amendment thereto] contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein not misleading or that the Prospectus [or any
amendment or supplement thereto,] at the time such Prospectus was issued, [at
the time any such amended or supplemented Prospectus was issued,] at the
Closing Date [and the Option Closing Date], contained or contains any untrue
statement of a material fact or omitted or omits to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances in which they were made, not misleading (except that we express
no comment as to financial statements, schedules and other financial data or
statistical data derived therefrom contained in the Registration Statement or
the Prospectus).

                 Opinion 9 and 13 are subject to the qualification that the
enforceability of the Agreement, the Documents and the Merger Agreement may be:
(i) subject to bankruptcy, insolvency, reorganization, moratorium or similar
laws affecting creditors' rights generally; and (ii) subject to general
principles of  equity (regardless of whether such enforceability is
<PAGE>   36
                                       5

considered in a proceeding at law or in equity) including principles of
commercial reasonableness or conscionability and an implied covenant of good
faith and fair dealing.

                 This letter is furnished by us solely for your benefit in
connection with the transactions referred to in the Agreement and may not be
circulated to, or relied upon by, any other person.

                 In rendering the foregoing opinion, counsel may rely, to the
extent they deem such reliance proper, on the opinions (in form and substance
reasonably satisfactory to Underwriters' counsel) of other counsel reasonably
acceptable to Underwriters' counsel as to matters governed by the laws of
jurisdictions other than the United States and the State of Delaware, and as to
matters of fact, upon certificates of officers of the Company and of government
officials; provided that such counsel shall state that the opinion of any other
counsel is in form satisfactory to such counsel.  Copies of all such opinions
and certificates shall be furnished to counsel to the Underwriters on the
Closing Date.

                               Form of Opinion of
                         Knobbe, Martens, Olson & Bear


                 1.       The portions of the Registration Statement and the
Prospectus entitled "Risk Factors--Uncertainties Associated with Patents and
Proprietary Rights" and "Business--Patents and Proprietary Information"
(together, the "Patent Paragraphs") are accurate and complete statements or
summaries of the matters set forth therein.

                 2.       There are no legal or governmental proceedings, other
than patent applications pending, relating to patent rights of the Company, to
which the Company is a party, and, to our knowledge, no such proceedings are
threatened or contemplated by governmental authorities or others and no basis
for any such proceedings exist.

                 3.       To our knowledge, the Company has not received any
communication in which it is alleged that the Company is infringing or
violating patent rights of third parties.

                 4.       The Company owns or possesses licenses or other
rights to use all patents, trade secrets, trademarks, service marks or other
proprietary information or materials necessary to conduct the business now
being or proposed to be conducted by the Company as described in the
Prospectus.

                 5.       Although we have not independently verified the
accuracy and completeness of the statements contained in the Registration
Statement and the Prospectus, nothing has come to our attention that would
cause us to believe that, at the time the Registration Statement became
effective under the Securities Act of 1933, as amended, the description and
statements in the Patent Paragraphs of the Registration Statement contained any
untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary to make the statements made therein
not misleading; or as of the date of the Prospectus or the date of this
opinion, the description and statements in the Patent Paragraphs of the
Prospectus contained or contain any untrue statement of a material fact or
omitted or omit to state a material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading.

Gentlemen:

You have requested our opinion with respect to certain matters in connection
with the filing by Alanex Corporation (the "Company") of a Registration
Statement on Form S-1 (the "Registration Statement") with the Securities and
Exchange Commission, including a related prospectus to be filed with the
Commission pursuant to Rule 424(b) of Regulation C (the "Prospectus")
promulgated under the Securities Act of 1933, as amended, and the underwritten
public offering of up to 2,875,000 shares (including 375,000 shares of Common
Stock for which the underwriters have been granted an over allotment option) of
the Company's Common Stock (the "Common Stock").

In connection with this opinion, we have (i) examined and relied upon the
Registration Statement and related Prospectus, the Company's Articles of
Incorporation and Bylaws, and the originals or copies certified to our
satisfaction of such records, documents, certificates, memoranda and other
instruments as in our judgment are necessary or appropriate to enable us to
render the opinion expressed below, (ii) assumed that the shares of Common Stock
will be sold by the underwriters at a price established by the Pricing Committee
of the Board of Directors of the Company and (iii) assumed that the
reincorporation of the Company referred to in the Registration Statement will be
effective prior to the issuance of the Common Stock.

On the basis of the foregoing, and in reliance thereon, we are of the opinion
that the Common Stock, when sold and issued in accordance with the Registration

                                PROMISSORY NOTE

$1,000,000                                              San Diego, California

        1.      FOR VALUE RECEIVED, the undersigned, ALANEX CORPORATION, (the
"Maker"), promises to pay to AMGEN INC., a Delaware corporation ("Lender"), or
place or places which the Lender may designate in writing from time to time, the
principal amount of One Million Dollars ($1,000,000) or such lesser amount as
may actually be advanced to Maker, with interest from the date of advancement on
the unpaid principal balance hereunder at the rate   percent  (  %) per annum
(on the basis of a 365-day year and the actual number of days elapsed).  the
unpaid principal balance of the obligation at any time shall be the total
amount advanced hereunder less the amount of principal repayments made by or
for Maker hereunder.  Lender shall undertake to endorse hereon the amount of the
principal advance, repayments and outstanding balances from time to time;
provided, that any failure to make such notation or endorsement shall not affect
Maker's continuing obligations under this Note.  In no event shall such
interest be charged under this Note which would violate any applicable usury
law.  The principal amount under this Note together with all accrued and unpaid
interest thereon, plus any other amounts then owing pursuant to this Note,
shall be due and payable in full on          , (the "Maturity Date") without
notice and without the need for any action or election by Lender; provided,
however, that: (a) if such date is not a normal business day, such payment
shall not be due until the first business day thereafter and (b) upon a Default
(as defined in that certain Termination and Redemption Agreement between Maker
and Lender effective as of June    , 1996 (the "Agreement")) all such amounts 
shall automatically become immediately due and payable without presentment, 
demand, protest or other notice of any kind, all of which are hereby waived by 
Maker.  All accrued and unpaid interest shall be due and payable in arrears in 
monthly installments commencing on         and continuing 

                                      -1-
<PAGE>   18
thereafter on the same numerical day of each subsequent calendar month, except
as otherwise provided in clauses (a) and (b) of the preceding sentence.

        2.  Each payment under this note shall first be credited against
accrued and unpaid interest, and any remainder shall be credited against
principal.  Any prepayment shall be without penalty except that interest shall
be paid to the date of payment on the principal amount then outstanding.

        3.  Principal and interest shall be payable in lawful money of the
United States of America by check hand delivered to Lender or by federal funds
wire upon Lender's request, in which case applicable wiring instructions will
be provided.

        4.  If default occurs with respect to any payment due under this Note,
including, without limitation, failure to pay any principal and accrued
interest when due:  (i) interest shall thereafter accrue on the entire unpaid
principal balance hereunder at the same rate as that set forth hereinabove (on
the basis of a 365-day year and the actual number of days elapsed); (ii) Maker
promises to pay all costs and expenses, including attorneys' fees, incurred by
the holder hereof in collecting or attempting to collect the indebtedness under
this Note, whether or not any action or proceeding is commenced; and (iii)
Maker hereby waives the right to plead any and all statutes of limitation as a
defense to a demand hereunder to the full extent permitted by law.  

        5.  None of the provisions hereof and none of the Lender's rights or
remedies hereunder on account of past or future defaults shall be deemed to
have been waived by the Lender's acceptance of any past due installments or by
any indulgence granted by the Lender to Maker.

        6.  Maker hereby waives presentment, demand, protest and notice thereof
or of dishonor, and agrees that it shall remain liable for all amounts due
hereunder notwithstanding any extension of time or change in the terms of
payment of this Note granted by any holder hereof or any delay or failure by
the holder hereof to exercise any rights under this Note or the Agreement.

<PAGE>   19
        7.  This Note shall be governed by and construed in accordance with the
laws of the State of California.

        8.  Maker acknowledges, represents and agrees that:  (a) this Note
evidences indebtedness of Maker due Lender as a result of a loan (the "Loan")
in the aggregate principal amount of One Million Dollars ($1,000,000) or such
lesser aggregate principal amount as may actually be advanced to Maker by
Lender on the date hereof pursuant to the terms of Section 5 of the Agreement;
(b) nothing contained herein, in the Agreement or in any conduct of
representatives of Lender shall obligate Lender or shall be construed as an
obligation of or commitment by Lender to loan, advance, or arrange to provide
any additional funds to Maker;  (c) the representations and warranties made by
Maker to Lender as of the date hereof pursuant to Section 5 of the Agreement
are true, complete and correct as of the date hereof;  (d) Lender shall have no
responsibility whatsoever for Maker's financial condition or any changes in
Maker's financial condition; and (e) Maker shall indemnify and hold Lender and
its affiliates and its and their respective officers, directors, employees and
representatives harmless from any and all damages (whether or not arising out
of third party claims) arising from this Note or the Loan.

        9.  Until the unpaid principal and interest is repaid in full, Maker
hereby agrees to repay sums due under this Note (including accrued and unpaid
interest and principal, without any need for Lender to demand repayment) at any
and all such times as Maker receives Proceeds (as defined in the Agreement), by
an amount equal to fifty percent (50%) of all such Proceeds received.  Such
amounts shall be paid by Maker to Lender not later than ten (10) days following
Maker's receipt of the same.

        10.  Maker represents, warrants and covenants to Lender that the
proceeds of the Loan will be used by Maker only as provided in Section 5 of the
Agreement.

Amgen, Inc.
1840 DeHavilland Drive
Thousand Oaks, CA 91320

Dear Sir or Madam:

We have acted as counsel for Alanex Corporation, a California corporation (the
"Company"), in connection with the issuance and sale of (i) a warrant to
purchase Four Hundred Fifty Thousand (450,000) shares of the Company's Common
Stock (the "New Warrant") and (ii) a promissory note in the principal amount of
Four Million Five Hundred Thousand ($4,500,000) dollars (the "Alanex Promissory
Note"), to Amgen Inc., a Delaware Corporation ("Amgen") (the Alanex Promissory
Note and the New Warrant, collectively, are referred to as the "Related
Agreements"), under the Termination and Redemption Agreement dated as of June
28, 1996 (the "Agreement"). We are rendering this opinion pursuant to Section
3.3(iv)(d) of the Agreement. Except as otherwise defined herein, capitalized
terms used but not defined herein have the respective meanings given to them in
the Agreement.

With your consent, in connection with this opinion, we have examined and relied
upon the representations and warranties as to factual matters contained in and
made pursuant to the Agreement by the parties thereto and upon originals or
copies certified to our satisfaction of such records, documents, certificates,
opinions, memoranda and other instruments as in our judgement are necessary or
appropriate to enable us to render the opinion expressed below.  Where we
render an opinion "to the best of our knowledge" or concerning an item "known
to us" or our opinion otherwise refers to our knowledge, it is based solely
upon (i) an inquiry of attorneys within this firm who perform legal services
for the Company, (ii) receipt of a certificate executed by an officer of the
Company covering such matters, and (iii) such other investigation, if any, that
we specifically set forth herein.

In rendering this opinion, we have assumed: the genuineness and authenticity of
all signatures on original documents; the authenticity of all documents
submitted to us as originals; the conformity to originals of all documents
submitted to us as copies; the accuracy, completeness and authenticity of
certificates of public officials; and the due authorization, execution and
delivery of all documents (except the due authorization, execution and delivery
by the Company of the Agreement and the Related Agreements), where
authorization, execution and delivery are prerequisites to the effectiveness of
such documents. We have also assumed: that all individuals executing and
delivering

                          [COOLEY GODWARD LETTERHEAD]

Amgen Inc.

documents had the legal capacity to so execute and deliver; that the Agreement
and the Related Agreements are obligations binding upon you; that you have filed
any required California franchise or income tax returns and have paid any
required California Franchise or income taxes; and that there are no extrinsic
agreements or understandings among the parties to the Agreement that would
modify or interpret the terms among of the Agreement or the Related Agreements
or the respective rights or obligations of the parties thereunder.

        We have assumed that, at the Closing, Amgen will deliver to the Company
the certificate or certificates representing the Amgen Shares for redemption.

        With regard to our opinion in paragraph 3 below, we express no opinion
regarding any law or governmental rule or regulation regarding maximum
allowable interest rates.  In addition, in paragraph 3 below, with respect to
enforceability, we express no opinion as to the company's compliance with (i)
Chapter 5 of the California Corporations Code or (ii) the laws relating to
fraudulent conveyances. We have also, for purposes of paragraph 3 below,
assumed (i) the due authorization, execution and delivery by the creditors
named in the Agreement of the consent contemplated by Section 3.5 thereof (the
"Consents"), and (ii) the sufficiency of the consideration received by the
creditors therefor.  Any such Consents by the named creditors in no way impair
any rights of any other creditor whose claims may arise from the payment to
Amgen of any amounts under the Alanex Promissory Note to the return of such 
amounts.

        With regard to our opinion in paragraph 5 below with respect to material
defaults under any material agreement known to us, we have relied solely upon
(i) a list supplied to us by the Company, a copy of which has been supplied to
you, of material agreements to which the Company is a party, or by which it is
bound, and (ii) an examination of the items on the foregoing list; we have made
no further investigation.

        Our opinion is expressed only with respect to the federal laws of the
United States of America and the laws of the State of California.  We express no
opinion as to whether the laws of any particular jurisdiction apply, and no
opinion to the extent that the laws of any jurisdiction other than those
identified above are applicable to the subject matter hereof.  We are not
rendering any opinion as to compliance with any antifraud law, rule or
regulation relation to securities, or to the sale or issuance thereof.

        On the basis of foregoing, in reliance thereon and with the foregoing
qualifications, we are of the opinion that:

1.  The Company has been duly incorporated and is a validly existing corporation
    in good standing under the laws of the State of California.

2.  The Company has the requisite corporate power and authority to own or lease
    its property and assets and to conduct its business as it is currently being
    conducted and, to the best of our knowledge, is not required to qualify as a
    foreign corporation to do business in any other jurisdiction in the United
    States.  The Company has the corporate power and authority to execute,
    deliver and perform its obligations under the Agreement and the Related
    Agreements.

3.  The Agreement and the Related Agreements have been duly and validly
    authorized, executed and delivered by the Company and constitute valid and
    binding obligations of the Company, enforceable against the Company in
    accordance with their respective terms, except as enforceability may be
    subject to or limited by (a) general equity principles and to limitations on
    the availability of equitable relief including specific performance; (b) the
    effect of applicable bankruptcy, insolvency, reorganization, moratorium or
    other laws relating to or affecting the rights of creditors; (c) limitations
    on a borrower's ability to waive rights or benefits given by statute or
    otherwise; (d) limitations on the right of a lender to impose added charges
    for late payments or defaults by the borrower, where it is determined that
    such charges bear no reasonable relation to the damage suffered by the
    lender as a result of such late payments; and (e) the effect of California
    Civil Code Section 1717 on the recovery of attorneys' fees in contract
    actions.  Any creditors executing the Consent are not entitled under Chapter
    5 of the California Corporations Code to recovery of the fair market value
    of the Related Agreements or amounts paid to Amgen under the Alanex
    Promissory Note.

4.  The Warrant Shares issuable upon exercise of the New Warrant have been duly
    authorized and reserved for issuances by all necessary corporate action on

                              3. RESEARCH PROGRAM

        3.1  PURPOSE AND SCOPE.  The purpose of the Collaboration is to
characterize novel, non-peptide ligands with desired opioid receptor ligand
binding affinity. During the Research Term and subject to the terms and
conditions of this Agreement, ALANEX will use its good faith, scientific and
business judgement to conduct the Research Program and to furnish the facilities
and personnel necessary to carry out its responsibilities under the Research
Program pursuant to the funding provided in Section 4 hereof.

        3.2  ALANEX  RESPONSIBILITIES.

                3.2.1  ALANEX shall (i) apply ALANET(TM)-I to the Chemical
Entity Data supplied by ASTRA to assemble a database of analogs of the
compounds for which the Chemical Entity Data was supplied and, (ii) apply
ALANET(TM)-II to that database to identify new compounds with desired affinity
at opioid receptors and to characterize a 3-D pharmacophore based on those
compounds. ALANEX acknowledges that ASTRA will determine the Research Program
direction within the target of development of compounds with opioid receptor
binding activity. The target may be changed subject to mutual agreement by the
parties.

                3.2.2  ALANEX will use its peptide, organic and medicinal
chemistry, PDPS(TM) technology, and current and future databases to synthesize,
isolate, purify and characterize novel non-peptide ligands with desired
affinity to opioid receptors.

                3.2.3  ALANEX, with the assistance of ASTRA, will set up
specific opioid receptor binding assays for the routine testing of compounds
synthesized at ALANEX.

                3.2.4  ALANEX will provide to ASTRA adequate quantities of pure
and characterized compounds identified by ALANEX that exhibit desired binding
affinity to opioid receptors. Adequate Quantities shall mean amounts required
for verification of in vitro affinity, physiochemical properties and early
pharmacology studies.

                3.2.5  ALANEX shall provide ASTRA with 3-D pharmacophore
information about peptide-like and/or non-peptide candidates that fulfill the
requirements of the hypothesis. This will be an iterative process that will
require refinement of the pharmacophore hypothesis after the synthesis and
testing of new compounds.

        3.3  ASTRA  RESPONSIBILITIES.

                3.3.1  ASTRA shall be responsible for providing, at its own
discretion, the Chemical Entity Data to enable ALANEX to assemble a database
for ALANET(TM)-I that is adequate for the application of ALANET(TM)-II.

                3.3.2  ASTRA may carry on an effort independent of ALANEX,
utilizing pharmocophore information supplied by ALANEX, to synthesize organic
compounds with the required characteristics for binding to the opioid receptors
of interest.

        3.4  RESEARCH DURATION.  The Research Program shall be performed during
the Research Term hereof, subject to extension upon mutual agreement of the
parties.

        3.5  RECORD KEEPING.  ALANEX will keep accurate scientific records
relating to the Research Program and will make such records available to ASTRA
or its authorized representative throughout the Term of the Agreement during
normal business hours upon reasonable notice.

        3.6  ALANEX  AGREEMENT REGARDING RESEARCH.  ALANEX agrees that during
the Research Term, as may be extended or terminated in accordance with the terms
of this Agreement, and for twelve (12) months thereafter, it will not, alone or 
together with any third party, engage in research regarding opioid receptor
ligands. Nothing herein shall limit ALANEX's ability to conduct research
regarding any subject other than opioid receptor ligands during the period
described in the immediately preceding sentence or ALANEX's ability to conduct
research regarding any subject following the expiration of such period.

         4.2 FTE PAYMENTS. ALANEX will be paid ***********  per year per FTE,
adjusted annually by the Consumer Price Index of San Diego, California, USA,
over the preceding calendar year starting 1995 (the "FTE Rate"). Payments will
be made on a quarterly basis commencing not later than December 20, 1994. The
initial number of FTE's will be *******. These will include one (1) FTE for a
computational chemist, *************  for synthetic organic-medicinal
chemistry, and one (1) FTE for a pharmacologist to perform receptor ligand
binding assays. The FTE constitutes the entire compensation for the services
performed under this Agreement.

        4.3 FUNDING COMMITMENT MODIFICATION. At any time during the term of a
Research Program, either Party may propose in writing an increase or decrease
of the number of FTE's. ALANEX may request a change in the FTE Rate for the
remaining term of such Research Program; after providing competent proof and
explanation that ALANEX's research department cost structure exceeds the FTE
rate set forth in Section 4.2  and upon approval of ASTRA, which approval shall
not be unreasonably withheld, the FTE rate will change accordingly.

        Notwithstanding the above, ASTRA is entitled upon three (3) months'
prior written notice to ALANEX to terminate the Research Program for any
reason. Upon such premature termination of the Research Program, the remainder
of this Agreement will continue to be in full force and effect until terminated
in accordance with Article 10 below, and ASTRA will, as entire compensation for
the premature termination of the Research Program, compensate ALANEX for
reasonable and unavoidable wind-up costs not exceeding the FTE rate for six (6)

research and development activities, may produce one or more drug candidates
based, inter alia, on the Results, the Research Program and/or the
Collaboration, the NOVO NORDISK Patent Rights and other intellectual property
rights, know-how and technology belonging to NOVO NORDISK. In addition hereto,
it may be necessary for NOVO NORDISK to carry out such production to have
access, and ALANEX is willing to grant such access, to know-how, trade secrets
and technology belonging to ALANEX necessary to make, have made, use, promote,
and sell one or more candidate drugs. In the event that NOVO NORDISK exercises
the option described in the immediately preceding sentence, the license
acquired shall be sublicenseable and royalty bearing. Unless otherwise agreed,
said license shall be governed by a license agreement which, in all material
respects, shall be identical to the License Agreement attached hereto as
Appendix 3.

        In the event that NOVO NORDISK has included in the Research Program a
Non collaboration Product and, in such event, comes under an obligation to pay
royalties or other remuneration to a third party for having obtained the full

by more than ***.

        In the event that the Chemical Entity Data supplied by NOVO NORDISK
includes hits with a Ki value lower than one (1) mic.M, the milestone payments 
provided for in Section 7 hereof and the royalty payments contemplated in this
Section 8, and the standard License Agreement attached hereto as Exhibit 3,
shall be subject to renegotiation in good faith, it being recognized by ALANEX
that NOVO NORDISK shall be granted more favorable terms in such situation based
on the additional input and know-how, thus provided by NOVO NORDISK towards the
collaboration.

        1.8     "TERRITORY" shall mean the entire world.

                  2. LICENSING OF PATENT RIGHTS AND TECHNOLOGY

        2.1     Licensor grants to Licensee the exclusive right and license
under the ALANEX Patent Rights and any related know-how to make, have made, use
or sell Licensed Product within the Territory.

<PAGE>   19
                                              * CONFIDENTIAL TREATMENT REQUESTED

             The license granted herein shall, subject to third party rights,
include all improvements made by Licensor during the term hereof in the method
of manufacture or administration of Licensed Product.

        2.2  Licensor grants to licensee and its Affiliates the unrestricted
right to sub-license any portion or all of the ALANEX Patent Rights and the
related know-how to make, have made, use or sell Licensed Product within the
Territory; provided that prior notice shall be given to Licensor. Licensee
shall remain primarily liable for the performance of such sub-licensees. Each
sub-licensee shall enter into a written sub-license agreement having the same
obligations towards Licensor as those provided for herein.

                             3. MILESTONE PAYMENTS

        3.1  NOVO NORDISK's obligation to make milestone payments in accordance
with Section 7 of the Collaboration Agreement shall not be waived or otherwise
affected by entering into this Agreement.

                         4. ROYALTIES AND PAYMENT TERMS

        4.1  Licensee will pay Licensor a royalty for the Sale of Licensed
Product at a royalty rate based on the amount of Net Proceeds of Sale, according
to the following schedule:

        Annual Net Proceeds of Sale     Royalty rate applicable to Sales
                                        in described interval

               *****************                  ***
            ********************                  ***
            ********************                  ***
            ********************                  ***

        4.2  Only one royalty shall be paid under this Agreement for each
Licensed Product, regardless of the number of claims of patents or patent
applications applicable thereto or the number of Sales of the same Licensed
Product by Licensee or any sublicensee of Licensee.

        4.3  While Licensee will have the right to conduct Sales through
Affiliates and sub-licensees, Licensee shall be responsible for the payment of
all royalties and the performance of all other obligations hereunder for such 
Sales.

        4.4  In the event of the grant of one or more compulsory licenses in a
country in the Territory to a third party under any Patent included in the
ALANEX Patent Rights for a specific Licensed Product, the applicable royalty
rate as provided in Section 4.1 will be reduced by the same royalty payable by
that 

                                       3

<PAGE>   20
                                               *CONFIDENTIAL TREATMENT REQUESTED

third party in respect of the sale and manufacture of the specific Licensed
Product in that country of the Territory.

        4.5     All royalties and other payments due hereunder shall be paid in
U.S. Dollars. All royalties and other payments due hereunder shall be originated
from a bank located in the U.S.A. and shall be made by bank wire transfer in
immediately available funds to such account as Licensor shall designate before
such payment is due. If at any time legal restrictions in any country in the
Territory prevent the prompt remittance in the manner set forth in this Section
4.5 of part or all royalties owning with respect to Sales of Licensed Product in
such country, then the parties shall meet and mutually determine a lawful manner
of remitting the restricted part of such royalty payment so long as such legal
restrictions exit.

        4.6     With respect to Sales of Licensed Product invoiced in a currency
other than U.S. Dollars the Net Proceeds of Sales of licensed Product and the
royalties payable shall be calculated using the average closing buying rate for
such currency quoted in the continental terms method of quoting exchange rates
by the European version of the Wall Street Journal, or, in the absence of quoted
exchange rates from the European version of the Wall Street Journal, a
comparable bank or financial institution, on each of the last business days of
each month in the quarter prior to the date of payment.

        4.7     If required to do so by law, Licensee may withhold from royalty
payments due to Licensor any withholding or similar taxes required to be
withheld or collected on behalf of Licensor, provided that any such deductions
for the payment of such taxes are supported by duly executed receipts.

        4.8     NOVO NORDISK shall be entitled to deduct any milestone payments
made in respect of the relevant Program Compound from any royalties due
hereunder for the sale of the corresponding Licensed Products, it being
understood, however, that NOVO NORDISK shall in the event be allowed to
withhold more than **************** of the royalty amount otherwise due.

                     5. RECORD KEEPING PAYMENT AND REPORTS

        5.1     Licensee shall keep a complete and correct account of the
amounts sold and Net Proceeds of Sale of Licensed Product, and shall be
obliged to keep such account for three (3) years after the year of making of a
royalty payment as provided in Article 5.2.

        5.2     Licensee shall within sixty (60) days after the end of each
calendar quarter send to Licensor a written statement, certified by an
authorized officer of Licensee showing Net Proceeds of Sales of Licensed
Product, the deductions used to calculate such amount, withholding taxes, if
any, required by law to be deducted in respect of such sales, and the applicable
currency exchange


                                       4

                                              * CONFIDENTIAL TREATMENT REQUESTED

calculations. Such statements shall be accompanied by a payment of the total
amount of royalty then due. If no royalty is due, licensee shall nevertheless
render a statement to reflect such fact. Licensee shall also furnish such
additional information as Licensor may reasonably request from time to time to
assure that the proper royalty amount was paid.

        5.3     Not more than once in a calendar year, at Licensor's request
and cost, Licensee agrees to allow Licensor's independent auditors to audit the
relevant books and records of Licensee relating to the Net Proceeds of Sale and
the determination of the royalty; provided, however, if any such audit reflects
a discrepancy of greater than 5% in the amount of royalties payable, Licensee
shall bear the cost of such audit.

                                 6. WARRANTIES

        6.1     Licensor represents and warrants that, to the best of its
knowledge, upon due investigation, as of the effective date of this Agreement:

                6.1.1  it is the sole owner of the entire right, title and
                       interest in the ALANEX patent Rights and related know-how
                       and has the right to enter into this Agreement;

                6.1.2  there are no administrative or judicial proceedings
                       contesting the inventorship, ownership, validity of
                       enforceability of any element of ALANEX patent Rights;
                       and

                6.1.3  except as provided under or in connection with the
                       Collaboration Agreement, it has granted no prior license
                       or assignment of the ALANEX Patent Rights and the related
                       know-how within the Territory.

                               7. PAID-UP LICENSE

        7.1     Licensee's obligation to pay royalties under Section 4.1 shall
cease and this Agreement will remain in effect as a paid-up, non-exclusive,
royalty-free license of the ALANEX Patent Rights and related know-how to make,
have made, use and sell the Licensed Product in a country covered by the
Territory upon the date of the (i) expiration of the last of any Patent (product
patents only) belonging to NOVO NORDISK in that country, or (ii) twelve (12)
years after the first commercial sale (i.e., after all required regulatory and
pricing approvals) of the Licensed Product in such country. If the applicable
ALANEX Patent Rights expire before the end of such twelve (12) years, royalties
payable under Section 4.1 shall be reduced by **************************,
provided that if material generic competition should develop for the Licensed
Product, the royalty rate shall be further reduced by another
************************** on a country-by-country basis.

                                 8. TERMINATION

        8.1  If Licensee or Licensor at any time materially defaults in
rendering any of the reports required hereunder, or in the payment of any money
due hereunder or in fulfilling any of the other obligations or conditions
hereunder, either party may waive the default, or if electing not to waive the
default, such party shall notify the other in writing of said default and allow
sixty (60) days (or thirty (30) days in the case of non-payment) for the other
to correct the default. If at the end of said time period the default remains
uncorrected, the aggrieved party may terminate this Agreement and any licenses
granted thereunder by giving written notice of termination to the other party.
Upon the giving of such notice, this Agreement and any licenses granted
hereunder shall terminate immediately.

        8.2 Licensee shall have the right to terminate this Agreement at any
time upon giving Licensor sixty (60) days' written notice. Licensee shall upon
such termination becoming effective pay to Licensor all royalties accrued prior
to such termination date. 

                                 9. LITIGATION

        9.1 If any judgment holds claims of the ALANEX Patent Rights covering
such licensed Product, its use or manufacture unenforceable or invalid (whether
or not such judgment is further reviewable), any royalties which are due to be
paid to Licensor after the date of judgment under Section 4.1 shall be reduced
by ***********************; provided that if material generic competition 
should develop for the Licensed Product, the royalty rate shall be further 
reduced by another ***********************, on a country-by-country basis. In 
the event that the validity or enforceability of the claims is reinstated, the
full royalty rate or amount specified in Section 4.1 shall be restored and 
Licensee will pay Licensor the difference between the full and reduced royalty,
plus *************** annual interest, for the period when the reduced royalty 
rate was in effect.

        9.2 Licensor agrees to notify Licensee in writing if the validity,
infringement or priority of invention of any of the ALANEX Patent Rights is put
in issue by any person.

        9.3 Upon learning of any infringement of the ALANEX Patent Rights,
Licensee will promptly discuss the matter with Licensor. If such infringement
is likely to materially and adversely affect the sale of the Licensed Product,
Licensee shall have the right at any time upon written notice to Licensor to
take whatever action Licensee in its reasonable discretion deems appropriate,
including appropriate court action, to terminate the infringement or to enter
into a settlement agreement with the infringing party or parties. Such action
shall include the defense of any action in which the validity or infringement
of the 


                                       6

<PAGE>   23

ALANEX Patent Rights is placed in issue by a third party, e.g. by way of a
declaratory judgment action. Any such action or defense shall be under the sole
control of Licensee at Licensee's expense and with counsel of Licensee's
choosing and of whom Licensor does not reasonably object. Licensor shall have
the right to participate in such proceedings and to share equally all costs.
Licensor shall also be entitled to have a counsel of its choice observe the
progress of such action. Licensor agrees to cooperate fully with licensee and
provide Licensee with any assistance that Licensee might require in said action
(at Licensee's expense, as regards out-of-pocket expenses) including joining
with Licensee as a named party in any law suit in which licensee may become
involved in its efforts to terminate the infringement or confirm the validity
of the ALANEX Patent Rights. If Licensee does not elect within sixty (60) days
after such notice to so control the defense of such suit, Licensor may
undertake such control at its own expense, and Licensee shall then have the
right to be represented by advisory counsel of its own selection and at its own
expense, and Licensee shall cooperate fully with Licensor and provide Licensor
with any assistance that Licensor might require in said action.

        9.4 After deduction of all legal fees and expenses of either party, any
sums received by Licensee, if Licensee controlled the suit, as damages or
settlement for infringement shall be shared equally if Licensor participated in
such proceedings (and shared the legal costs); otherwise, Licensee shall retain
fifty percent (50%) of such net recovery. If licensee does not elect to control 
the defense of any suit as provided in Section 9.3 above, the Licensor
undertakes such control, Licensor shall retain such net recovery.

                              10. CONFIDENTIALITY

        10.1 In consideration of disclosure by either of the parties to the
other party of confidential information in written or oral form or in the form
of samples, the recipient and the recipient's Affiliates undertake for a period
of ten (10) years from the date of disclosure to treat received information as
strictly secret and therefore not to disclose it to any third party (except
reliable employees, sub-licensees and Affiliates under similar secrecy
obligations), and to make no commercial use of it except for the purposes of
this Agreement. This obligation does not apply to:

                10.1.1 information which, at the time of disclosure, is already
in the public domain;

                10.1.2 information which, after disclosure, becomes a part of
the public domain by publication through no violation of this Agreement;

                10.1.3 information which the recipient is able to prove to have
been in possession of prior to any disclosure; or

<PAGE>   24


                10.1.4 information which is hereafter lawfully disclosed by a 
third party to the recipient, which third party did not acquire the information
under a still effective secrecy obligation.


                                  11. NOTICES

      11.1  All notices required or provided for use in this Agreement shall be

                               12. FORCE MAJEURE

        12.1  Each of the parties hereto shall be excused from the performance
of its obligations (other than the obligation to pay monies due) and shall not
be liable for damages to the other in the event that such performance is
prevented by circumstances beyond its effective control. Such excuse from
performance shall continue for so long as the condition responsible for such
excuse continues and for a thirty (30) day period thereafter. For the purposes
of this Agreement, circumstances beyond the control of a party which excuse
that party from performance shall include, but not limited to, acts of God,
acts, regulations or laws of any government, injunction or judgment of any
court, war, civil commotion, destruction of facility or materials by fire,
earthquake, storm or other casualty, labor disturbances, epidemic and failure
of public utilities or common carrier.


                               13. MISCELLANEOUS

        13.1  This Agreement shall be construed and interpreted in accordance
with the laws of the State of New York. The English wording of this Agreement
shall prevail. The parties agree to submit to arbitration under the
International Chamber of Commerce any dispute arising from this Agreement which
cannot 


                                       8

be solved in an amicable manner. The arbitration shall take place in New York
City, New York, and shall not include the conciliation procedure. Judgment upon
the award rendered may be entered in any court in any country for execution.

        13.2   Both parties hereto agree that it is not the intention to
violate any public policy, statutory or common laws. However, if any sentence,
paragraph, clause or combination of the same is in violation of any state or
federal law or is found to be otherwise unenforceable by a court from which
there is no appeal, or no appeal is taken, such sentences, paragraphs, clauses
or combinations of the same shall be deleted and the remainder of this
Agreement shall remain binding.

        13.3  This Agreement and the covenants herein contained shall be
binding and inure to the benefit of the parties hereto and their heirs,
assigns, successors and legal representatives. Except as otherwise provided
herein, this Agreement shall not be assignable.

        13.4  This Agreement constitutes the entire understanding between the
parties with respect to the subject matter hereof and shall, except for the
Collaboration Agreement, supersede all previous communications,
representations, understandings and agreements, either oral or written, between
the parties with respect to the subject matter of this Agreement. This
Agreement may be amended or modified only by a written instrument executed by
all of the parties hereto.

        13.5  The paragraph headings contained herein are for reference only;
they are not a part of this Agreement nor shall they in any way affect the
interpretation thereof.

        13.6  The express or implied waiver by either party of a breach of any
provision of this Agreement shall not constitute a continuing waiver of other
breaches of the same or other provisions of this Agreement.

IN WITNESS WHEREOF, the parties hereto have affixed their authorized signatures
as of the date given.

                (g)  ********** upon the first NDA-equivalent filing approved
for the first therapeutic indication for any Product containing a Lead Compound
in a Major European Country or Japan.

The first achievement of each of the milestone events described in Section
8.3(a)-(c) need not be by the same Compound. Roche Bioscience will be obligated
to make the milestone payments set forth above in Section 8.3(a)-(c) only one
time with respect to each molecular target, such as *****. Notwithstanding the
foregoing, separate Milestone Payments with respect to Section 8.3(d)-(g) shall
not be paid with respect to any particular Product if it represents a change in
form or dosage of such product for which Milestones have previously been paid.

        8.4  ROYALTIES

                (a)  Roche Bioscience shall pay to Alanex the following royalty
on Net Sales of each Product based on or incorporating any Lead Compound and
sold by Roche Bioscience or its Affiliates or sublicensees:

                        (i)  ** of Net Sales in all countries where Patent
Protected on the portion of aggregate annual worldwide Net Sales up to
************* and

                        (ii)  ** of Net Sales in all countries where Patent
Protected on the portion of aggregate annual worldwide Net Sales exceeding 
*************

                        (iii)   **** of Net Sales in all countries where a
Product is not Patent Protected.

                (b)  If Roche Bioscience is required to pay royalties to a
third party (other than an Affiliate of Roche Bioscience), to make, use or sell
Product for which Roche Bioscience is currently paying royalties to Alanex to
avoid infringing such third party's patent rights (the "Additional Royalties"),
then the Royalties to be paid to Alanex by Roche Bioscience pursuant to this

Royalties, provided, however, that at no time during the Royalty Term will
Alanex receive less than a  **** royalty on Net Sales whether or not there is
Patent Protection.

                (c)  Royalties for Net Sales of any Product in any given
country shall be paid for a period equal to the Royalty Term for such Product
in such country.

SECTION 9  PAYMENT; RECORDS; AUDITS

        9.1  PAYMENT; REPORTS.  All royalty payments due to either Party under
this Agreement shall be paid within 60 days of the end of each calendar
quarter, unless otherwise specifically provided herein. Each payment of
royalties shall be accompanied by a report of Net Sales of Products in
sufficient detail to permit confirmation of the accuracy of the royalty 
payment made.



                                       12
<PAGE>   14

        9.2  EXCHANGE RATE; MANNER AND PLACE OF PAYMENT. Royalty payments and
reports for the sale of Products shall be calculated and reported for each
calendar quarter. With respect to each quarter, for countries other than the
United States, whenever for the purpose of calculating royalties conversion
from any foreign currency shall be required, such conversion shall be made as 
follows:

             (i)  when calculating the Adjusted Gross Sales, the amount of such
sales in foreign currencies shall be converted into Swiss Francs as computed in
the central Roche's Swiss Francs Sales Statistics for the countries concerned,
using the average monthly rate of exchange at the time for such currencies as
retrieved from the Reuters System;

             (ii) when calculating the royalties on Net Sales, such conversion
shall be at the average rate of the Swiss Franc to the United States dollar as
retrieved from the Reuters System for the applicable calendar quarter.

All payments owed under this Agreement shall be made by wire transfer, unless
otherwise specified by the receiving Party.

        9.3  LATE PAYMENTS. In the event that any payment, including royalty,
milestone and research payments, due hereunder is not made when due, the
payment shall accrue interest from the date due at the rate of 1.5% per month;
provided that in no event shall such rate exceed the maximum legal annual
interest rate. The payment of such interest shall not limit any Party from
exercising any other rights it may have as a consequence of the lateness of any 
payment.

        9.4  RECORDS AND AUDIT.

             (a)  During the term of this Agreement and for a period of two
years thereafter, Roche Bioscience shall keep complete and accurate records
pertaining to the sale or other disposition of Products in sufficient detail to
permit Alanex to confirm the accuracy of all payments due hereunder. Alanex
shall have the right to cause an independent, major (big six) certified public
accountant firm reasonably acceptable to Roche to audit such records to confirm
Roche Bioscience's Net Sales for the preceding year. Any information obtained
during such audit shall be treated as Confidential Information. Such audits may
be exercised during normal business hours once a year upon at least thirty (30)
working days' prior written notice to Roche Bioscience. Alanex shall bear the
full cost of such audit unless such audit discloses a variance of more than 5%
from the amount of the Net Sales reported by Roche Bioscience for such audited
period. In such case, Roche Bioscience shall bear the full cost of such audit.
The terms of this Section 9.4 shall survive any termination or expiration of
this Agreement for a period of two years.

           (b)  During the term of this Collaboration and for a period of two
years thereafter, Alanex shall keep complete and accurate records documenting
the time spent by Alanex employees in direct support of the Collaboration.
Roche Bioscience shall have the right to audit such records to confirm Alanex
time records and research costs for the preceding year upon thirty (30) working
days' prior written notice. Such audits may be exercised during normal business
hours once a year upon notice to Alanex.

         9.5  TAXES. All turnover and other taxes levied on account of the
royalties and other payments accruing to each Party under this Agreement shall
be paid by the Party receiving such royalty or other payment for its own
account, including taxes levied thereon as income to the receiving Party. If
provision is made in law or regulation for withholding, such tax shall be
deducted from the royalty or other payment made by the Party making such 
payment to the proper taxing authority and a receipt of payment of the tax
secured and promptly delivered to the Party entitled to the royalty. Each Party
agrees to assist the other Party in claiming exemption from such deductions or
withholdings under any double taxation or similar agreement or treaty from time
to time in force.

SECTION 10  PATENT RIGHTS AND INFRINGEMENT

        10.1  OWNERSHIP OF ROCHE BIOSCIENCE PATENTS AND ALANEX COMPOUND
PATENTS. Alanex shall retain all right, title and interest in and to any Alanex
Compound Patents and to the Alanex Discovery Technology, subject only to the
exclusive licenses expressly granted herein. Roche Bioscience shall retain all
right, title and interest in and to any Roche Bioscience Patents, subject only
to the licenses expressly granted herein.

        10.2  DISCLOSURE OF PATENTABLE INVENTIONS. In addition to the
disclosures required under Section 4.4, each Party shall provide to the other
any invention disclosure submitted in the normal course and disclosing an
Invention arising in the course of the Collaboration. Such Invention
disclosures shall be provided to the other Party promptly after submission and
in no event later than 30 days after the disclosure was submitted to patent
counsel. In addition, the Research Management Committee will from time to time
provide information relating to Inventions and will recommend to the Parties
the filing of applications for Inventions it believes are patentable.

        10.3  PATENT FILINGS.

              (a)  Alanex Compounds.

                   (i) The Parties intend to establish broad patent protection
for Alanex Compounds and other patentable inventions arising from the Research.
The parties intend that Roche Bioscience shall file and prosecute all patent
applications covering the Lead Compounds, but the parties recognize that some
initial patent work may need to be performed prior to the selection of Alanex a
Compound as a Lead Compound. Subject to the above, Alanex shall file and
prosecute all patent applications covering Inventions containing claims which
cover Alanex Compounds or other patentable inventions arising from the Research,
provided, however, that Alanex shall give Roche Bioscience the right of first
refusal to file and prosecute such Alanex Compound Patents on behalf of Alanex.
If Roche Bioscience declines such opportunity, Alanex shall file and prosecute
such Alanex Compound Patents, using counsel reasonably acceptable to Roche
Bioscience. Upon selection of such Compound as a Lead Compound (the "Selection
Date"), Alanex shall turn over to Roche Bioscience all files relating to such
Patent filing and prosecution and Roche Bioscience shall have full
responsibility for such Patent filing and prosecution.  Roche Bioscience shall
pay Alanex for all Patent Costs incurred up to the Selection Date of filing,
prosecuting and maintaining such

                                       14
<PAGE>   16

Patents necessary to protect such Lead Compound. Alanex shall provide invoices
of Patent Costs as costs are incurred and Roche Bioscience shall reimburse
Alanex within 30 days of the invoice date. The Parties shall each bear their
own internal costs and expenses of filing, prosecuting and maintaining such
Alanex Compound Patents. Roche Bioscience shall maintain all Patents that issue
on such applications. 

                (ii) If Roche Bioscience elects not to handle the filing or
prosecution of such Patent, Alanex shall provide Roche Bioscience with drafts
of any patent application covering Alanex Compounds or other patentable 
inventions arising from the Research prior to filing that application, allowing
adequate time for review and comment by Roche if possible; provided, however,
that Alanex shall not be obligated to delay the filing of any patent
application. Roche shall maintain any such patent application in confidence,
pursuant to Section 11.

                (iii) If Alanex decides, at any time, not to file or maintain
an application or a Patent as provided hereunder, it shall give Roche notice to
this effect and upon such notice Roche shall have the right, but not the
obligation, to file and maintain, such application or Patent, in its own name
and at its own expense, and, if it so elects to file and maintain, Alanex shall
assign to such other Party the rights in such application or Patent.

        (b)  Lead Compounds.

                (i) To the extent not previously filed in accordance with
Subsection 10.3(a) above, Roche Bioscience shall file and prosecute all patent
applications covering Inventions containing claims which cover Lead Compounds
or other patentable inventions arising from the Research.  Roche Bioscience
shall bear all Patent Costs of filing, prosecuting and maintaining such Lead
Compound Patents. Roche Bioscience shall maintain all Patents that issue on 
such applications.

                (ii) Roche Bioscience shall provide Alanex with drafts of any
patent application covering Lead Compounds prior to filing that application,
allowing adequate time for review and comment by Alanex if possible; provided,
however, that Roche Bioscience shall not be obligated to delay the filing of
any patent application. Alanex shall maintain any such patent application in
confidence, pursuant to Section 11.

                (iii) If Roche Bioscience decides on a world-wide basis, at any
time, not to file or maintain an application on all Lead Compound Patents as
provided hereunder, it shall give Alanex notice to this effect and upon such
notice Alanex shall have the right, but not the obligation, to file and
maintain, such applications or Patents, in its own name and at its own expense,
and, if it so elects to file and maintain, Roche Bioscience shall assign to
such other Party the rights in such applications or Patents.

     10.4  ENFORCEMENT RIGHTS.

        (a)  DEFENSE AND SETTLEMENT OF THIRD PARTY CLAIMS. If a Third Party 
asserts that a patent or other right owned by it is infringed by the
manufacture, use or sale of any Product, Roche Bioscience shall be solely
responsible for defending against any such
       
                                       15

<PAGE>   17

assertions at its cost and expense.

                (b)  INFRINGEMENT BY THIRD PARTIES WITH RESPECT TO PRODUCTS. If
any Patent is infringed by a Third Party in any country in connection with the
manufacture, use and sale of any Product in such country, the Party to this
Agreement first having knowledge of such infringement shall promptly notify the
other in writing. The notice shall set forth the facts of that infringement in
reasonable detail. Roche Bioscience shall have the primary right, but not the
obligation, to institute, prosecute, and control any action or proceeding with
respect to such infringement, by counsel of its own choice against such third
party in the name of Alanex and/or in the name of Roche Bioscience, and to join
Alanex as a party plaintiff (at Roche Bioscience's expense) if required, and 
Alanex shall have the right, at its own expense, to be represented in any 
action involving an Alanex Patent by counsel of its own choice. If Roche
Bioscience fails to bring an action or proceeding within a period of 120 days
after having knowledge of infringement of an Alanex Patent, Alanex shall have
the right to bring and control any such action by counsel of its own choice, and
Roche Bioscience shall have the right to be represented in any such action by
counsel of its own choice at its own expense. If one Party brings any such
action or proceeding, the other Party agrees to be joined as a Party plaintiff
if necessary to prosecute the action and to give the first Party reasonable
assistance and authority to file and prosecute the suit.

                (c)  MONETARY AWARDS. Any damages or other monetary awards
recovered shall be allocated first to the costs and expenses of the Party
bringing suit, then to the costs and expenses, if any, of the other Party. Any
amounts remaining shall be allocated two-thirds to the Party bringing suit and
one-third to the other Party. A settlement or consent judgment or other
voluntary final disposition of a suit under Sections 10.4(b) may be entered
into only with the consent of the Party not bringing the suit, which consent
shall not be unreasonably withheld.


SECTION 11  CONFIDENTIALITY

        11.1  NONDISCLOSURE. During the term of this Agreement and for a period
of five years after termination thereof, each Party will maintain all
Confidential Information in trust and confidence and will not disclose any
Confidential Information to any third Party or use any Confidential Information
for any purpose except (i) as expressly authorized by this Agreement, (ii) as
required by law or court order, (iii) as provided in Section 11.3, or (iv) to
its Affiliates. Each Party may use such Confidential Information only to the
extent required to accomplish the purposes of this Agreement. Each Party will
use at least the same standard of care as it uses to protect proprietary or
confidential information of its own to ensure that its Affiliates, employees,
agents, consultants and other representatives do not disclose or make any
unauthorized use of the Confidential Information. Each Party will promptly
notify the other upon discovery of any unauthorized use or disclosure of
the Confidential Information.

        11.2  EXCEPTIONS. Confidential Information shall not include any
information which the receiving Party can prove by competent evidence:

                (a) is now, or hereafter becomes, through no act or failure to
act on the part

                                       16
<PAGE>   18


of the receiving Party, generally known or available;

                (b) is known by the receiving Party at the time of receiving
such information, as evidenced by its records;

                (c) is hereafter furnished to the receiving Party by a third
Party, as a matter of right and without restriction on disclosure;

                (d) is independently developed by the receiving Party without
the aid, application or use of Confidential Information; or

                (e) is the subject of a written permission to disclose provided
by the disclosing Party.

        11.3  FINANCIAL TERMS. The Parties agree that the material financial
terms of this Agreement will be considered Confidential Information of both
Parties. Notwithstanding the foregoing, either Party may disclose such terms as
are required to be disclosed in its financial statements or under strictures of
confidentiality to bona fide potential sublicensees. Either Party shall have
the further right to disclose the material financial terms of this Agreement
under strictures of confidentiality to any potential acquiror or merger
partner. 

        11.4  PUBLICATIONS. Each Party to this Agreement recognizes that the
publication of papers regarding results of Research hereunder and other
information resulting from the Collaboration, including oral presentations and
abstracts, may be beneficial to both Parties provided such publications are
subject to reasonable controls to protect Confidential Information. In
particular, it is the intent of the Parties to maintain the confidentiality of
any Confidential Information included in any foreign patent application until
such foreign patent application has been published. Accordingly, each Party
shall have the right to review and approve any paper proposed for publication
by the other Party, including oral presentations and abstracts, which utilizes
data generated from the Collaboration and/or includes Confidential Information
of the other Party. Before any such paper is submitted for publication, the
Party proposing publication shall deliver a complete copy to the other Party at
least 45 days prior to submitting the paper to a publisher. The receiving Party
shall review any such paper and give its comments to the publishing Party
within 30 days of the delivery of such paper to the receiving Party. With
respect to oral presentation materials and abstracts, the Parties shall make
reasonable efforts to expedite review of such materials and abstracts, and
shall return such items as soon as practicable to the publishing Party with
appropriate comments, if any, but in no event later than 30 days from the date
of delivery to the receiving Party. The publishing Party shall comply with the
other Party's request to delete references to such other Party's Confidential
Information in any such paper and agrees to withhold publication of same for an
additional 180 days in order to permit the Parties to obtain patent protection,
if either of the Parties deem it necessary, in accordance with the terms of
this Agreement.

shall be resolved by final and binding arbitration conducted in San Diego
County, California under the then current Licensing Agreement Arbitration Rules
of the American Arbitration Association ("AAA"); provided, however, that
depositions shall be permitted as follows: each Party may take no more than
three depositions with a maximum of six hours of examination time per
deposition, and each such deposition shall take place in San Diego County,
California, unless otherwise agreed by the Parties. The arbitration shall be
conducted by one arbitrator who is knowledgeable in the subject matter which is
at issue in the dispute and who is selected by mutual agreement of the Parties
or, failing such agreement, shall be selected according to the AAA rules. In
conducting the arbitration, the arbitrator shall apply the California Evidence
Code, and shall be able to decree any and all relief of an equitable nature,
including but not limited to such relief as a temporary restraining order, a
preliminary injunction, a permanent injunction, or replevin of property. The
arbitrator shall also be able to award actual, general or consequential
damages, but shall not award any other form of damage (e.g., punitive damages).
The Parties shall share equally the arbitrator's fees and expenses pending the
resolution of the arbitration unless the arbitrator, pursuant to its right but
not its obligations, requires the non-prevailing Party to bear all or any
portion of the costs of the prevailing Party. The decision of the arbitrator
shall be final and may be sued on or enforced by the Party in whose favor it
runs in any court of competent jurisdiction at the option of such Party.

                             ******* RESEARCH PLAN


       GOAL:   To identify and initiate the clinical development of a selective
               **************** antagonist.

    Phase I:   Evaluate relevant pharmacophore information, establish high 
               throughput assays, and initiate screening of Alanex compound
               database. Initiate development of new chemistry methodology for
               the synthesis targeted libraries.

Alanex computational chemistry will begin an analysis of the pharmacophore
requirements for binding to the various ************** in order to facilitate
the design of new combinatorial libraries with the goal of creating compounds
that display selectivity for the ****************.

Alanex will obtain from Roche Bioscience cell lines that have been transfected
with the human **************** and the protocol for the binding assay in
order to adapt the assay for high throughput screening at Alanex. If necessary
to expedite the project, Alanex will purchase membrane preparations prepared
from cells that contain the receptor. Alanex will establish the **************
binding assay within six weeks of receiving the appropriate cell line
from Roche Bioscience. Once the high throughput screen for ****************
is established, testing of the Alanex compound database for activity at
**************** will commence.

Alanex will begin development of new synthetic strategies in preparation for
the development of targeted libraries, and in order to extend the range of
exploratory libraries.

   Phase II:   Complete screening of Alanex database. Design, synthesize and
               screen targeted libraries. Initial determination of receptor 
               selectivity.
    
Based on the results of screening and the computational modeling of known
compounds, Alanex will design novel targeted libraries, using precursors
synthesized at Alanex as well as those obtained from commercial sources. Active
compounds will be tested for binding activity in a variety of assay systems in
order to determine the selectivity profiles for different chemical series. The
types of assays will be determined by the Research Management Committee.
Modification of active compounds by both combinatorial and medicinal chemistry
methods will proceed.

  Phase III:    Optimization of active compounds. Detailed pharmacological
                analysis of most active compounds. Establish optimization plan
                for most active series.

Highly active compounds will be extensively characterized and further optimized
according to a plan established by the Research Management Committee.

market value of such consideration.

         3.2   ROYALTIES. Alanex agrees to pay Licensor during the term of this
Agreement a royalty equal to **************************  of Net Sales of 
Licensed Products.

         3.3   PAYMENTS; REPORTS. Payments made pursuant to Sections 3.1 and 3.2
above shall be payable in U.S. dollars. Payments made under Section 3.1 above
shall be made within thirty (30) days of Alanex' receipt of milestone payments
from its third party sublicensees. The first royalty payment under Section 3.2
shall cover all royalties due on Net Sales of Licensed Products during the
calendar quarter when such sales commence and shall be made forty-five (45) days
after the end of such quarter. Thereafter royalty payments shall be due
forty-five (45) days after each succeeding calendar quarter and shall cover the
royalties earned during such calendar quarter. Alanex agrees to provide written
reports to Licensor with such royalty payments setting forth the total number of
Licensed Products sold during the applicable period. In the event that Alanex is
required to withhold taxes imposed on such payments in any country, Alanex will
remit such taxes to the proper authorities, reduce payment to Licensor
accordingly and supply Licensor with all relevant documentation in Alanex's
possession so that Licensor may recover such taxes to the extent permissible.

         3.4   RECORDS RETENTION. Alanex will keep, and will cause its
Affiliates and sublicensees to keep, complete and accurate records pertaining to
the sale of Licensed Products in sufficient detail to permit Licensor to confirm
the accuracy of calculations of all payments due hereunder. Such records will be
maintained for a three (3) year period following the year in which any such
payments were made hereunder.

         3.5   AUDIT REQUEST. No more frequently than once a year, Licensor will
have the right to engage, at its own expense, an independent certified public
accountant reasonably acceptable to Alanex to examine Alanex's records to
determine, with respect to any calendar year, the correctness of any report or
payment made under this Agreement. Any such audit will be conducted under

as to Licensor), worldwide license under the Licensed Technologies to discover,
develop, manufacture, use, offer for sale, sell and import Licensed Products.
Licensor retains the right to practice the Licensed Technologies for

this Agreement at all times.

         2.3 LICENSED PATENTS. Licensor shall notify Alanex of each new
patentable invention subject to this Agreement at least thirty (30) days in
advance of filing any patent application on such invention. If Alanex notifies

for reimbursement of patent costs related to such invention, then such patents
shall not be included within the Licensed Patents and shall not be subject to
the terms of this Agreement.

         2.4 DISCLOSURE OF LICENSED KNOW-HOW. During the term of this Agreement,
Licensor shall use reasonable efforts to provide Alanex with all tangible and
intangible components of the Licensed Know-how.


                                    ARTICLE 3

                                  CONSIDERATION


         3.1 PATENT COSTS. Alanex agrees to reimburse Licensor in accordance
with Section 4.1 for all documented costs incurred by Licensor in connection
with the filing, prosecution and maintenance of the Licensed Patents. Alanex
will reimburse Licensor within thirty (30) days of receipt of such
documentation.

         3.2 MILESTONE PAYMENTS. Alanex agrees to pay to Mount Sinai an amount
equal to **************** of any milestone payments which Alanex may receive
from third party sublicensees upon the achievement of human clinical or
regulatory milestones with Licensed Products. License fees, equity investments,
bona fide loans, payments for research and development by Alanex and payments
other than the milestones described above shall not be subject to this Section
3.2. If Alanex receives consideration in a form other than cash, Alanex may pay
Licensor pursuant to this Section 3.2 either in kind or in cash based upon the
fair market value of such consideration.

         3.3 ROYALTIES. Alanex agrees to pay Licensor during the term of this
Agreement a royalty equal to **************************  of Net Sales of 
Licensed Products.

         3.4 PAYMENTS; REPORTS. Payments made pursuant to Sections 3.2 and 3.3
above shall be payable in U.S. dollars. Payments made under Section 3.2 above
shall be made within thirty (30) days of Alanex' receipt of milestone payments
from its third party sublicensees. The first royalty payment under Section 3.3
shall cover all royalties due on Net Sales of Licensed Products during the
calendar quarter when such sales commence and shall be made forty-five (45) days
after the end of such quarter. Thereafter royalty payments shall be due
forty-five (45) days after each succeeding calendar quarter and shall cover the
royalties earned during such calendar quarter. Alanex agrees to provide written
reports to Licensor with such royalty payments setting forth the total number of
Licensed Products sold during the applicable period. In the event that Alanex is
required to withhold taxes imposed on such payments in any country, Alanex will
remit such taxes to the proper authorities, reduce payment to Licensor
accordingly


                                       3.
<PAGE>   4
and supply Licensor with all relevant documentation in Alanex's possession so
that Licensor may recover such taxes to the extent permissible.

         3.5 RECORDS RETENTION. Alanex will keep, and will cause its Affiliates
and sublicensees to keep, complete and accurate records pertaining to the sale
of Licensed Products in sufficient detail to permit Licensor to confirm the
accuracy of calculations of all payments due hereunder. Such records will be
maintained for a three (3) year period following the year in which any such
payments were made hereunder.

         3.6 AUDIT REQUEST. No more frequently than once a year, Licensor will
have the right to engage, at its own expense, an independent certified public
accountant reasonably acceptable to Alanex to examine Alanex's records to
determine, with respect to any calendar year, the correctness of any report or
payment made under this Agreement. Any such audit will be conducted under
reasonable confidentiality restrictions. In the event that any such examination
reveals that payments made to Licensor hereunder are incorrect by more than
seven percent (7%) in any audited period, Alanex shall reimburse Licensor for
the costs of such audit in addition to promptly remitting the amount of any
underpayment with interest at the prime rate reported in the Wall Street Journal
on the last day of the month prior to the date of such remittance.


                                    ARTICLE 4

                            PATENTS AND INFRINGEMENT


         4.1 PATENT PROSECUTION AND MAINTENANCE. Licensor shall have the right,
but not the obligation, to file, prosecute and maintain all patent applications
and patents included in the Licensed Patents using counsel reasonably acceptable
to Alanex. Licensor and Alanex shall cooperate to determine appropriate
prosecution strategy with respect to each Licensed Patent, including the
countries in which such patent will be pursued. Licensor will provide Alanex
with copies of all correspondence with patent authorities promptly after receipt
or delivery. Licensor will provide Alanex with a reasonable opportunity to
review and comment on all patent filings in advance of filing. Alanex shall
reimburse Licensor for all documented costs, fees and expenses incurred by
Licensor in connection with the filing, prosecution and maintenance of the
Licensed Patents. In the event Licensor declines to file, prosecute or maintain
any application or patent within the Licensed Patents in any country, Licensor
shall give Alanex notice of such decision reasonably in advance of any filing
deadline applicable to such application or patent. Thereafter, Alanex may, at
its own expense, continue to prosecute or maintain such application or patent.

         4.2 PATENT ENFORCEMENT. Alanex shall have the first right, but not the
obligation, to enforce the Licensed Patents in infringement, interference or
other proceedings and to file suit in its own name or in the name of Licensor.
All costs, fees and/or expenses incurred in connection with such enforcement of
the Licensed Patents shall be borne by Alanex. To the extent that damages are

         Alanex agrees to indemnify, hold harmless and defend Licensor, its
trustees, officers, medical and professional staff, employees, students and
agents, and their respective successors and assigns (the "Indemnitees"), against
any liability, damage, loss or expense (including reasonable attorneys fees and

businesses the size of Alanex or engaged in the business in which Alanex is
engaged. Licensor will be named as an additional insured on any such insurance
and such insurance shall not be canceled without at least thirty (30) days
notice to Licensor. Alanex shall provide a certificate of insurance evidencing

                            NONSTATUTORY STOCK OPTION

                   _______________________, Optionee:

         ALANEX CORPORATION (the "Company") has this day granted to you, the
optionee named above, an option to purchase shares of the common stock of the
Company ("Common Stock"). This option is not intended to qualify as and will not
be treated as an "incentive stock option" within the meaning of Section 422 of
the Internal Revenue Code of 1986, as amended (the "Code").

         The grant hereunder is in connection with and in furtherance of the
Company's compensatory benefit plan for participation of the Company's employees
(including officers, directors and consultants) and is intended to comply with
the provisions of Rule 701 promulgated by the Securities and Exchange Commission
under the Securities Act of 1933, as amended (the "Act") and to satisfy the
requirements of Section 25102(f) of the California Corporate Securities Law of
1968, as amended.

         The details of your option are as follows:

         1. NUMBER OF OPTION SHARES AND VESTING. The total number of shares of
Common Stock subject to this option is __________________ (________). Subject to
the limitations contained herein, this option shall vest and become exercisable
[INSERT VESTING SCHEDULE].

         2. (a) EXERCISE PRICE. The exercise price of this option is
_____________ ($_______) per share.

            (b) METHOD OF PAYMENT. Payment of the exercise price per share is
due in full upon exercise of all or any part of each installment which has
accrued to you. You may elect, to the extent permitted by applicable statutes
and regulations, to make payment of the exercise price under one of the
following alternatives:

                (i) Payment of the exercise price per share in cash (including
check) at the time of exercise;

                (ii) Payment pursuant to a program developed under Regulation T
as promulgated by the Federal Reserve Board which, prior to the issuance of
Common Stock, results in either the receipt of cash (or check) by the Company or
the receipt of irrevocable instructions to pay the aggregate exercise price to
the Company from the sales proceeds;

                                       1.
<PAGE>   2

                (iii) Provided that at the time of exercise the Company's Common
Stock is publicly traded and quoted regularly in the Wall Street Journal,
payment by delivery of already-owned shares of Common Stock, held for the period
required to avoid a charge to the Company's reported earnings, and owned free
and clear of any liens, claims, encumbrances or security interests, which Common
Stock shall be valued at its fair market value on the date of exercise of the
option, or portion thereof, granted hereunder;

                (iv) Provided that the option exercise price for the
installment, or portion thereof, being purchased is at least one thousand
dollars ($1,000), payment pursuant to the deferred payment alternative as
described in paragraph 2(c) hereof; or

                (v) Payment by a combination of the methods of payment permitted
by subparagraph 2(b)(i) through 2(b)(iv) above.

             (C) CONDITIONS OF DEFERRED PAYMENT. In the event that you elect to
make payment of the exercise price pursuant to the deferred payment alternative:

                (i) Not less than twenty-five percent (25%) of the aggregate
exercise price shall be due at the time of exercise, not less than twenty-five
percent (25%) of said exercise price, plus accrued interest, shall be due each
year after the date of exercise, and final payment of the remainder of the
exercise price, plus accrued interest, shall be due three (3) years from the
date of exercise or, at the Company's election, upon termination of your
employment with the Company or an affiliate of the Company;

                (ii) Interest shall be payable at least annually and shall be
charged at the minimum rate of interest necessary to avoid the treatment as
interest, under any applicable provisions of the Code, of any portion of any
amounts other than amounts stated to be interest under the deferred payment
arrangement; and

                (iii) In order to elect the deferred payment alternative, you
must, as a part of your written notice of exercise, give notice of the election
of this payment alternative and, in order to secure the payment of the deferred
exercise price to the Company hereunder, if the Company so requests, you must
tender to the Company a promissory note and a security agreement covering the
purchased shares, both in form and substance satisfactory to the Company, and
such other or additional documentation as the Company may request.

         3. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary
contained herein, this option may not be exercised unless the shares issuable
upon exercise of this option are then registered under the Act or, if such
shares are not then so registered, the Company has determined that such exercise
and issuance would be exempt from the registration requirements of the Act. You
represent that you (i) are an officer or


                                       2.
<PAGE>   3
director of the Company, or (ii) have a preexisting personal or business
relationship with the Company or one or more of its officers, directors, or
controlling persons, or (iii) by reason of your business or financial experience
or the business or financial experience of your professional advisors who are
unaffiliated with and who are not directly or indirectly compensated by the
Company or any affiliate of the Company, you have the capacity to protect your
own interests in connection with the grant of this option. You also represent
that you are acquiring this option for your own account and not with a view to
or for sale in connection with any distribution of this security. You also
represent that you have acquired this option unaccompanied by the publication of
any advertisement. The Company may, upon advice of counsel to the Company, place
legends on stock certificates issued pursuant to the exercise of this option as
such counsel deems necessary and appropriate in order to comply with applicable
securities laws, including, but not limited to, legends restricting the transfer
of stock.

         4. MINIMUM EXERCISE. The minimum number of shares with respect to which
this option may be exercised at any one time is one hundred (100), except (a) as
to an installment subject to exercise, as set forth in paragraph 1, which
amounts to fewer than one hundred (100) shares, in which case, as to the
exercise of that installment, the number of shares in such installment shall be
the minimum number of shares, and (b) with respect to the final exercise of this
option this minimum shall not apply. In no event may this option be exercised
for any number of shares which would require the issuance of anything other than
whole shares.

         5. TERM. The term of this option commences on _____________ (the date
of grant) and, unless sooner terminated as set forth below, terminates on
____________ (the "Expiration Date" which date shall be no more than ten (10)
years from the date this option is granted). In no event may this option be
exercised on or after the date on which it terminates. This option shall
terminate prior to the expiration of its term as follows: three (3) months after
the termination of your continuous service to the Company as an employee,
consultant or director (your "Termination Date") for any reason or for no reason
unless:

             (a) such termination of service is due to your permanent and total
disability (within the meaning of Section 422(c)(6) of the Code), in which event
the option shall terminate on the earlier of the Expiration Date set forth above
or twelve (12) months following your Termination Date; or

             (b) such termination of service is due to your death, in which
event the option shall terminate on the earlier of the Expiration Date set forth
above or eighteen (18) months after your death; or


                                       3.
<PAGE>   4

             (c) during any part of such three (3) month period the option is
not exercisable solely because of the condition set forth in paragraph 3 above,
in which event the option shall not terminate until the earlier of the
Expiration Date set forth above or until it shall have been exercisable for an
aggregate period of three (3) months after your Termination Date; or

             (d) exercise of the option within three (3) months after your
Termination Date would result in liability under section 16(b) of the Securities
Exchange Act of 1934, in which case the option will terminate on the earlier of
(i) the Expiration Date set forth above, (ii) the tenth (10th) day after the
last date upon which exercise would result in such liability or (iii) six (6)
months and ten (10) days after your Termination Date with the Company or an
affiliate of the Company.

             This option may be exercised following your Termination Date only
as to that number of shares as to which it was exercisable on your Termination
Date under the provisions of paragraph 1 of this option.

         6. EXERCISE. (a) This option may be exercised, to the extent specified
above, by delivering a notice of exercise (in a form designated by the Company)
together with the exercise price to the Secretary of the Company, or to such
other person as the Company may designate, during regular business hours,
together with such additional documents as the Company may then reasonably
require.

             (b) By exercising this option you agree that:

                (i) as a precondition to the completion of any exercise of this
option, the Company may require you to enter an arrangement providing for the
cash payment by you to the Company of any tax withholding obligation of the
Company arising by reason of: (1) the exercise of this option; (2) the lapse of
any substantial risk of forfeiture to which the shares are subject at the time
of exercise; or (3) the disposition of shares acquired upon such exercise; and

                (ii) the Company (or a representative of the underwriters) may,
in connection with the first underwritten registration of the offering of any
securities of the Company under the Act, require that you not sell or otherwise
transfer or dispose of any shares of Common Stock or other securities of the
Company during such period (not to exceed one hundred eighty (180) days)
following the effective date (the "Effective Date") of the registration
statement of the Company filed under the Act as may be requested by the Company
or the representative of the underwriters. You further agree that the Company
may impose stop-transfer instructions with respect to securities subject to the
foregoing restrictions until the end of such period.

                                       4.

         7. COVENANT OF COMPANY. During the term of this option, the Company
shall keep available at all times the number of shares of stock required to
satisfy the exercise of such option.

         8. ADJUSTMENT UPON CHANGES IN STOCK. (a) If any change is made in the
stock subject to this option (through merger, consolidation, reorganization,
recapitalization, stock dividend, dividend in property other than cash, stock
split, liquidating dividend, combination of shares, exchange of shares, change
in corporate structure or other transaction not involving the receipt of
consideration by the Company), this option will be appropriately adjusted in the
type(s) and number of securities and price per share of stock subject to the
option. Such adjustments shall be made by the Board of Directors, the
determination of which shall be final, binding and conclusive. (The conversion
of any convertible securities of the Company shall not be treated as a
"transaction not involving the receipt of consideration by the Company.")

             (b) In the event of: (i) a merger or consolidation in which the
Company is not the surviving corporation; or (ii) a reverse merger in which the
Company is the surviving corporation but the shares of the Company's common
stock outstanding immediately preceding the merger are converted by virtue of
the merger into other property, whether in the form of securities, cash or
otherwise; or (iii) a sale of all or substantially all of the assets of the
Company, then, to the extent permitted by applicable law: (1) any surviving
corporation shall assume this option or shall substitute a similar option
(including an option to acquire the same consideration paid to stockholders in
the transaction described in this subparagraph 8(b)), if this option is still
outstanding, or (2) in the event any surviving corporation refuses to assume or
continue this option, or to substitute a similar option for this option (if
still outstanding), then this option shall become fully vested and exercisable
prior to such event and shall terminate after such acceleration of vesting if
not exercised at or prior to such corporate event. In the event of a dissolution
or liquidation of the Company, this option (if still outstanding) shall
terminate if not exercised prior to such event.

         9. TRANSFERABILITY. This option is not transferable, except by will or
by the laws of descent and distribution, and is exercisable during your life
only by you. By delivering written notice to the Company, in a form satisfactory
to the Company, you may designate a third party who, in the event of your death,
shall thereafter be entitled to exercise this option.

         10. OPTION NOT A SERVICE CONTRACT. This option is not an employment
contract and nothing in this option shall be deemed to create in any way
whatsoever any obligation on your part to continue in the employ of the Company,
or of the Company to continue your employment with the Company. In the event
that this option is granted to you in connection with the performance of
services as a consultant or director, or in the


                                       5.

event that this option is granted to you in connection with the performance of
services as an employee and you subsequently perform services as a consultant or
director, references to employment, employee and similar terms shall be deemed
to include the performance of services as a consultant or a director, as the
case may be, provided, however, that no rights as an employee shall arise by
reason of the use of such terms.

         11. NOTICES. Any notices provided for in this option shall be given in
writing and shall be deemed effectively given upon receipt or, in the case of
notices delivered by the Company to you, five (5) days after deposit in the
United States mail, postage prepaid, addressed to you at the address specified
below or at such other address as you hereafter designate by written notice to
the Company.

         12. AMENDMENT. This option may be amended by the Board of Directors at
any time; provided, however, that any change that would adversely affect your
rights in this option must first be approved by you in writing before becoming
effective.

         13. ADMINISTRATION. This option is subject to all interpretations,
amendments, rules and regulations which may from time to time be promulgated and
adopted by the Company. This authority shall be exercised by the Board, or by a
committee of one or more members of the Board in the event that the Board
delegates its authority to a committee. The Board, in exercise of this
authority, may correct any defect, omission or inconsistency in this option in a
manner and to the extent the Board shall deem necessary or desirable to make
this option fully effective. References to the Board shall mean the committee if
a committee has been appointed by the Board. Any interpretations, amendments,
rules and regulations promulgated by the Board shall be final and binding upon
the Company and its successors in interest as well as you and your heirs,
assigns, and other successors in interest.

             14. RIGHTS AS STOCKHOLDER. Neither you nor any person to whom this
option is transferred under paragraph 8 of this option shall be deemed to be the
holder of, or to have any of the rights of a holder with respect to, any shares
subject to this option unless and until such person has satisfied all
requirements for exercise of this option pursuant to its terms.

         Dated as of _________________.   

                                              Very truly yours,
