                               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 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 at 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, forms 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 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>   6
 
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. In addition, failures in the field of
combinatorial chemistry, whether by the Company or by others, could have an
adverse effect on the Company. 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
 
                                        6
<PAGE>   9
 
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
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 or find that the
development, manufacture or sale of its proposed products is materially and
adversely affected.
 
     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. One such agreement has been
terminated. Any future termination could have a material adverse effect on the
Company. 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, or that current or future collaborators will not pursue
alternative technology in preference to that of the Company, 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 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 revenues. Further, the Company's revenues from collaboration
agreements are 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 revenues 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 revenues are expected for a number
of years, if at all.
 
FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FUNDING
 
     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
 
                                        7
<PAGE>   10
 
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.
 
     The Company anticipates that it will need to raise additional capital 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 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 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.
 
                                        8
<PAGE>   11
 
     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 marketing 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 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."
 
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 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 one U.S. patent
application. 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, and 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.
 
     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 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 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
 
                                       10
<PAGE>   13
 
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. There is intense competition for such
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     % of the
outstanding Common Stock (     % of the outstanding Common Stock if the
overallotment option is exercised in full). In particular, upon completion of
this offering, Debar ERA, Inc. ("Debar") and The Jon and Caroline Jessen 1990
Family Trust (the "Jessen Family Trust") will in the aggregate beneficially
own     % of the outstanding Common Stock (     % of the outstanding Common
Stock if the over-allotment option is exercised in full). Julie Jessen, the
daughter of Jon Jessen, a 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
 
                                       11
<PAGE>   14
 
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
shares of Common Stock. Of these shares, all of the 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 under the Securities Act) without
restriction or registration under the Securities Act. The remaining 3,746,968
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. 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) 2,973,048 Restricted Shares (plus 511,775 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. 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. 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
 
                                       12
<PAGE>   15
 
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.
 
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 $          per share, investors
participating in this offering will incur an immediate, substantial dilution in
net tangible book value of $          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."

                                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 $       ($          if the
Underwriters' over-allotment option is exercised in full), 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 shares of Common Stock offered hereby (at an assumed
initial public offering price of $          per share) 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 $     million, or $          per share. This represents an
immediate increase in net tangible book value of $          per share to
existing stockholders and an immediate dilution of $          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 for working capital.
 
     To date, the Company's revenues under collaboration agreements have
consisted of project initiation fees, research fees and a milestone payment. The
Company earned revenue in 1994 and 1995 under collaboration agreements with
Amgen Inc. ("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 by mutual agreement in June
1996. In addition, the Company expects to earn revenue from a collaboration with
Roche Bioscience. 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 revenues.
 
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, due primarily to the signing of the Novo
Nordisk and the Roche Bioscience collaboration agreements.
 
     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 due to added expenses of increased corporate activities,
the 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
 
                                       18
<PAGE>   21
 
expense through June 30, 1996 was $3,000. Amortization of deferred compensation
over the next four fiscal years, including compensation recognized to date, will
aggregate $160,000 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. The 1995
revenues resulted from collaboration agreements with Amgen, Astra and Novo
Nordisk and consisted entirely of payments for research support. The 1994
revenues were attributable to research support payments from Amgen and Astra
Pharma and nonrefundable project initiation fees from Astra Pharma and Novo
Nordisk.
 
     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 staffing of administrative
personnel and expenses related to increases in general corporate activity.
General and administrative expenses totaled $162,000 in 1993.
 
     The Company's net loss decreased 23% 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 mutual 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."
 
     In June 1994, the Company secured $1.2 million in working capital financing
from Merrill Lynch Business Financial Services. 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. At June 30, 1996, $715,000 was outstanding on 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.
 
                                       19
<PAGE>   22
 
     The Company's 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. The Company's 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.

                                    BUSINESS
 
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, forms 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 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 were limited to
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 thirdparty
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 20 years. Furthermore, the time required to develop and
commercialize a drug has remained, on average, ten to 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>   25
 
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.

                                    (Chart)
 
     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 or targeted
and 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
large numbers 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
 
                                       24
<PAGE>   27
 
used in high throughput screening. Synthesized compounds can be purified using
Alanex's proprietary parallel chromatography technology.
 
  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>   28
 
     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) 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>   29
 
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>   30
 
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 novel molecular targets have been selected by Alanex and Novo Nordisk
as the basis for discovery of new drugs to treat diabetes. Addressing these two
new 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 each of the molecular targets for these programs. 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 $48 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 world. 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. Nine percent of the United States population suffers from depression and
8% from panic and generalized anxiety disorders.
 
                                       28
<PAGE>   31
 
Studies 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 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>   32
 
  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

  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 $4.8 million in additional funding to
support research at the Company in the field of the collaboration. To date,
Alanex has received $880,000 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 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. Roche Bioscience also has the
option, until September 27, 1996, 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 one U.S. patent application relating to
various aspects of its technology, including its PDPS and parallel synthesis
technology and certain of its compounds. 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 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.
 
                                       32
<PAGE>   35
 
     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, and 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 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 governmental regulation that might result from
future legislation or administrative action cannot be accurately predicted.

FACILITIES
 
     The Company currently leases 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 August 1, 1996, the Company had 43 full-time employees. Of the 43
full-time employees, 34 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 four 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 Class III will consist
of Dr. Hagler and Mr. Jessen. At each annual meeting of stockholders after the
initial classification, the successors to directors whose term will then expire
will be elected to serve
 
                                       37
<PAGE>   40
 
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.
 
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 appointed the
Compensation Committee. 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."
 
SCIENTIFIC ADVISORY BOARD
 
     The Company's Scientific Advisory Board ("SAB") is composed of scientists

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. 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
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
exercise, 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 August 1, 1996, the Company had granted Options under the 1993 Plan
to purchase an aggregate of 850,092 shares (net of cancellations) at exercise
prices ranging from $0.10 to $1.50 per share and 490,000
 
                                       40
<PAGE>   43
 
shares of Common Stock had been issued as restricted stock under the 1993 Plan,
all of which is currently vested. As of August 1, 1996, no Stock Awards had been
granted under the 1996 Plan.
 
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 August 1, 1996,
Non-Plan Options were outstanding to purchase an aggregate of 150,000 shares of
Common Stock at an exercise price of $0.10 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.
 
     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 will be substituted with similar
Stock Awards.
 
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 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 2,352,000 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 their 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. 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 August 1, 1996, the outstanding principal and accrued
interest under the promissory note was $12,651.
 
     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 August
1, 1996, the outstanding principal and accrued interest under the promissory
note was $52,500.

     In May 1996, Dr. Brown, President, Chief Executive Officer and a director
of the Company, borrowed $60,000 from the Company pursuant to an unsecured
promissory note bearing interest at the rate of 6.75% per annum. Accrued
interest is payable in three equal annual installments commencing May 1997, with
the entire principal amount and any accrued and unpaid interest becoming due in
May 1999. As of August 1, 1996, the outstanding principal and accrued interest
under the promissory note was $61,924.
 
     In May 1996, the Company entered into an employment agreement with Ms.
Youngers, the Director of Finance and Secretary of the Company. Under the
employment agreement, the Company will pay Ms. Youngers an annual base salary of
$108,000. In addition, Ms. Youngers will receive a bonus of $11,250 upon the
successful completion of the Company's initial public offering of Common Stock
and a second bonus of $11,250 upon the completion of one year of service with
the Company. In connection with the employment agreement, the Company granted to
Ms. Youngers an option to purchase 50,000 shares of Common Stock at an exercise
price of $0.10 per share, with such option vesting in equal monthly installments
over a four-year period; however, if Ms. Youngers is terminated by the Company
without cause during the first two years of employment with the Company, the
vesting of the option will be accelerated by a period of two years from the date
of termination and if Ms. Youngers is terminated by the Company without cause at
any time after the first two years of employment with the Company, the option
will accelerate by a period of one year from the date of termination.
 
     In July 1996, the Company entered into an arrangement with Dr. Brown which
provides that if Dr. Brown is terminated by the Company without cause, he will
be entitled to receive a severance payment in an amount equal to twelve months
of his base salary in effect at the time of his termination. In July 1996, the
Company entered into an arrangement with Dr. Polinsky which provides that if Dr.
Polinsky is terminated by the Company without cause, he will be entitled to
receive a severance payment in an amount equal to nine months of his base salary
in effect at the time of his termination.
 
     The Company has entered into indemnification agreements with each of its
executive officers and directors. See "Management -- Limitation of Liability and
Indemnification of Officers and Directors."

                          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 August 1, 1996, there were issued and outstanding 3,746,968 shares of
Common Stock held by 14 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 August 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
 
                                       46
<PAGE>   49
 
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 ______
shares of Common Stock. Of these shares, all of the ______ 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
3,746,968 shares are Restricted 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
 
                                       47
<PAGE>   50
 
of this Prospectus, (ii) 2,973,048 Restricted Shares (plus 511,775 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 ______ 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 charged by the Representatives.
 
     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        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 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 Company's record of operations, its current financial condition, its
future prospects, the market for its potential
 
                                       49

Company's industry in general, the general condition of the equity securities
market, the demand for similar securities of companies considered comparable to
the Company and other relevant factors.

                          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 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 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
 
     Research revenue is recognized at the time research and development
activities are performed under the terms of the research contracts. Contract
payments received in excess of amounts earned are recorded as deferred contract
research revenue. Nonrefundable project initiation fees are recognized as
revenue when received. Revenue from milestone payments is recognized when the
results or events stipulated in the agreement have been achieved.
 
  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 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

            DECEMBER 31, 1994 AND 1995 AND JUNE 30, 1996 (UNAUDITED)
 
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 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).
 
(4) PROPERTY AND EQUIPMENT
 
     Property and equipment are recorded at cost and consist of the following at
December 31, 1994 and 1995 and June 30, 1996:

$40,000, $300,000 and $322,000 for the years ended December 31, 1993, 1994 and

of the Internal Revenue Code Section 401(k). The 401k Plan was approved by the
IRS in 1995. The 401k Plan is for the benefit of all qualifying employees, and
permits employee voluntary contributions and Company profit sharing
contributions. At the discretion of the Board of Directors, the Company may
match employee contributions equal to a discretionary percentage of the
employee's salary reductions, limited to the maximum contribution allowable for
income tax purpose. Employer contributions vest proportionally over five years
of service. No employer contributions have been approved by the Board of
Directors through December 31, 1995.

Delaware corporation. As a result of the reincorporation, the accounts within
the consolidated financial statements have been retroactively restated for all
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.

     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 August 1, 1996, the
     Registrant granted non-statutory stock options to employees, officers,

     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

     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.

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.

                          AGREEMENT AND PLAN OF MERGER

         This AGREEMENT AND PLAN OF MERGER (hereinafter called the "Merger
Agreement") is made as of __________, 1996 by and between ALANEX CORPORATION, a
California corporation ("Alanex California"), and ALANEX CORPORATION, a Delaware
corporation ("Alanex Delaware"). Alanex California and Alanex Delaware are
sometimes referred to as the "Constituent Corporations."

         The authorized capital stock of Alanex California consists of thirty
million (30,000,000) shares of Common Stock and ten million (10,000,000) shares
of Preferred Stock. The authorized capital stock of Alanex Delaware consists of
forty million (40,000,000) shares of Common Stock, $.001 par value, and ten
million (10,000,000) shares of Preferred Stock, $.001 par value.

         The directors of the Constituent Corporations deem it advisable and to
the advantage of said corporations that Alanex California merge into Alanex
Delaware upon the terms and conditions herein provided.

         Following the Merger (as defined below) the subsidiaries of Alanex
California shall be the subsidiaries of Alanex Delaware.

         NOW, THEREFORE, the parties do hereby adopt the plan of reorganization
encompassed by this Merger Agreement and do hereby agree that Alanex California
shall merge into Alanex Delaware on the following terms, conditions and other
provisions:

1.                TERMS AND CONDITIONS

         (a)      MERGER. Alanex California shall be merged with and into Alanex
Delaware (the "Merger"), and Alanex Delaware shall be the surviving corporation
(the "Surviving Corporation") effective at 12:00 p.m. (Eastern Standard Time) on
_______, 1996 (the "Effective Time").

         (b)      SUCCESSION. At the Effective Time, Alanex Delaware shall
continue its corporate existence under the laws of the State of Delaware, and
the separate existence and corporate organization of Alanex California, except
insofar as it may be continued by operation of law, shall cease.

         (c)      TRANSFER OF ASSETS AND LIABILITIES. At the Effective Time, the
rights, privileges, powers and franchises, both of a public as well as of a
private nature, of each of the Constituent Corporations shall be vested in and
possessed by the Surviving Corporation, subject to all of the disabilities,
duties and restrictions of or upon each of the Constituent Corporations; and all
and singular rights, privileges, powers and franchises of each of the
Constituent Corporations, and all property, real, personal and mixed, of each 


                                       1.
<PAGE>   2

of the Constituent Corporations, and all debts due to each of the Constituent
Corporations on whatever account, and all things in action or belonging to each
of the Constituent Corporations shall be transferred to and vested in the
Surviving Corporation; and all property, rights, privileges, powers and
franchises, and all and every other interest, shall be thereafter the property
of the Surviving Corporation as they were of the Constituent Corporations, and
the title to any real estate vested by deed or otherwise in either of the
Constituent Corporations shall not revert or be in any way impaired by reason of
the Merger; provided, however, that the liabilities of the Constituent
Corporations and of their shareholders, directors and officers shall not be
affected and all rights of creditors and all liens upon any property of either
of the Constituent Corporations shall be preserved unimpaired, and any claim
existing or action or proceeding pending by or against either of the Constituent
Corporations may be prosecuted to judgment as if the Merger had not taken place
except as they may be modified with the consent of such creditors and all debts,
liabilities and duties of or upon each of the Constituent Corporations shall
attach to the Surviving Corporation, and may be enforced against it to the same
extent as if such debts, liabilities and duties had been incurred or contracted
by it.

         (d)      COMMON STOCK OF ALANEX CALIFORNIA AND ALANEX DELAWARE. At the
Effective Time, by virtue of the Merger and without any further action on the
part of the Constituent Corporations or their shareholders, (i) each share of
Common Stock of Alanex California issued and outstanding immediately prior
thereto shall be exchanged for one fully paid and nonassessable share of Common
Stock of Alanex Delaware; and (ii) each share of Common Stock of Alanex Delaware
issued and outstanding immediately prior thereto shall be canceled and returned
to the status of authorized but unissued shares.

                              AMENDED AND RESTATED

     The undersigned, Marvin R. Brown and Alexander Polinsky hereby certify
that:

     ONE:  They are the duly elected and acting President and Secretary,
respectively, of Alanex Corporation, a California corporation.

     TWO:  The articles of incorporation of this corporation are amended and
restated to read as follows:

                                       I.

     The name of the corporation is Alanex Corporation.

                                      II.

     The purpose of this corporation is to engage in any lawful act or activity
for which a corporation may be organized under the General Corporation Law of
California other than the banking business, the trust company business or the
practice of a profession permitted to be incorporated by the California
Corporations Code.

                                      III.

     A.   Classes of Stock.  This corporation is authorized to issue two (2)
classes of shares, to be designated "Common" and "Preferred" and referred to
herein as the "Common Shares" or the "Preferred Shares" respectively. The total
number of Common Shares the corporation is authorized to issue is Thirty Million
(30,000,000). The total number of the Preferred Shares the corporation is
authorized to issue is Ten Million (10,000,000).

          The board of directors of the corporation may divide the Preferred
Shares into any number of series. The board of directors shall fix the
designation and number of shares of each such series. The board of directors may
determine and alter the rights, preferences, privileges and restrictions granted
to and imposed upon any wholly unissued series of the Preferred Shares. The
board of directors (within the limits and restrictions of any resolution adopted
by it, originally fixing the number of shares of any series) may increase or
decrease the number of shares of any such series after the issue of shares of
that series, but not below the number of then outstanding shares of such series.
<PAGE>   2
     B.   Rights, Preferences, Privileges and Restrictions of the Series A
Preferred Stock.

          1.   Designation of Series A Preferred Stock. Four Million (4,000,000)
shares of Preferred Stock are designated Series A Preferred Stock (the "Series A
Preferred") with the rights, preferences and privileges specified herein.

          2.   Dividend Rights of Series A Preferred. The holders of the then
outstanding shares of Series A Preferred shall be entitled to receive dividends
at the rate of $0.09 per share per annum when, as and if declared by the Board
of Directors out of any funds legally available therefor, prior and in
preference to any declaration or payment of any dividend on the Common Stock of
this corporation ("Common") payable other than in Common or other securities and
rights convertible into or entitling the holder thereof to receive, directly or
indirectly, additional shares of Common. Such dividends shall not be cumulative.

          3.   Liquidation Preference. In the event of any liquidation,
dissolution or winding up of the corporation, either voluntary or involuntary,
the holders of the Series A Preferred shall be entitled to receive, prior and in
preference to any distribution of any of the assets or surplus funds of the
corporation to the holders of the Common by reason of their ownership thereof,
the sum of (i) $1.51 per share for each share of Series A Preferred then held by
them and (ii) an amount equal to all declared but unpaid dividends on the Series
A Preferred then held by them. If, upon the occurrence of such event, the assets
and funds thus distributed among the holders of the Series A Preferred shall be
insufficient to permit the payment to such holders of the full aforesaid
preferential amount, then the entire assets and funds of the corporation legally
available for distribution shall be distributed ratably among the holders of the
Series A Preferred in proportion to the preferential amount each such holder
would have been entitled to receive pursuant to this Section 3 if such
distribution had been sufficient to permit the full payment of such
preferential amount. After payment has been made to the holders of the Series A
Preferred of the full amounts to which they shall be entitled as aforesaid, the
holders of the Common shall be entitled to receive all remaining assets of the
corporation. For purposes of this Section 3, a liquidation, dissolution or
winding up of the corporation shall be deemed to be occasioned by, or to
include, the corporation's sale of all or substantially all of its assets or the
acquisition of this corporation by another entity by means of merger or
consolidation resulting in the exchange of the outstanding shares of this
corporation for securities or consideration issued, or caused to be issued, by
the acquiring corporation or its subsidiary.

                                      -2-
<PAGE>   3
          4.   Conversion. The holders of the Series A Preferred shall have
conversion rights as follows (the "Conversion Rights"):

               a.   Optional and Automatic Conversion. Each share of Series A
Preferred shall be convertible at the option of the holder thereof, without
payment of additional consideration, at any time after the date of issuance of
such share, at the office of the corporation or any transfer agent for the
Series A Shares of Common as is determined by dividing $1.51 by the Conversion
Price, determined as hereinafter provided, in effect at the time of conversion.
The price at which shares of Common shall be deliverable upon conversion (the
"Conversion Price") of the Series A Preferred shall initially be $1.51 per share
of Common. Such initial Conversion Price shall be subject to adjustment as
hereinafter provided.


                    Each share of Series A Preferred shall automatically be
converted into shares of Common at the then effective Conversion Price in
the event of either (i) the closing of a firm commitment underwritten public
offering pursuant to an effective registration statement under the Securities
Act of 1933, as amended (the "Act"), covering the offer and sale of Common
(whether for the account of the corporation or for the account of one or more
shareholders of the corporation) of the corporation to the public at an
aggregate offering price of not less than $10,000,000 and at a public offering
price (prior to underwriters' discounts and expenses) equal to or exceeding
$7.50 per share of Common (as adjusted for any stock dividends, combinations or
splits with respect to such shares) or (ii) the written consent of holders of
more than 50% of the then outstanding shares of Series A Preferred voting as a
class. In the even of the automatic conversion of the Series A Preferred upon a
public offering as aforesaid, the conversion of Series A Preferred shall be
deemed to have occurred automatically at the closing of such public offering.

               b.   Mechanics of Conversion. No fractional shares of Common
shall be issued upon conversion of Series A Preferred. In lieu of any fractional
shares to which the holder would otherwise be entitled, the corporation shall
pay cash equal to such fraction multiplied by the then effective Conversion
Price. Before any holder of Series A Preferred shall be entitled to convert the
same into full shares of Common, it shall surrender the certificate or
certificates therefor, duly endorsed, at the office of the corporation or of
any transfer agent for the Series A Preferred, and shall give written notice to
the corporation at such office that it elects to convert the same (except that
no such written notice of election to convert shall be necessary in the event of
an automatic conversion pursuant to Section 4(a)). The corporation shall, as
soon as practicable thereafter, issue and deliver at such office to such holder
of Series A Preferred a certificate or certificates,

                                      -3-
<PAGE>   4
registered in such names as specified by the holder, for the number of shares of
Common to which he shall be entitled as aforesaid and a check payable to the
holder in the amount of any cash amounts payable as the result of a conversion
into fractional shares of Common, and any accrued and unpaid dividends on the
converted Series A Preferred. Such conversion shall be deemed to have been made
immediately prior to the close of business on the date of such surrender of the
shares of Series A Preferred to be converted, and the person or persons entitled
to receive the shares of Common issuable upon such conversion shall be treated
for all purposes as the record holder or holders of such shares of Common on
such date (except that in the event of an automatic conversion pursuant to
Section 4(a) such conversion shall be deemed to have been made immediately prior
to the closing of the offering referred to in such clause of Section 4(a)). If
the conversion is in connection with an underwritten offer of securities
registered pursuant to the Act, the conversion may, at the option of any holder
tendering Series A Preferred for conversion, be conditioned upon the closing
with the underwriter of the sale of securities pursuant to such offering, in
which event the person(s) entitled to receive the Common issuable upon such
conversion of the Series A Preferred shall not be deemed to have converted such
Series A Preferred until immediately prior to the closing of such sale of
securities.


               c.   Adjustments for Subdivisions, Dividends, Combinations or
Consolidations of Common.

                    (1)  In the event the outstanding shares of Common shall be
combined or consolidated, by reclassification or otherwise, into a lesser number
of shares of Common, the Conversion Price in effect immediately prior to such
combination or consolidation shall, concurrently with the effectiveness of such
combination or consolidation, be proportionately increased.


                    (2)  In the event the corporation shall declare or pay any
dividend on the Common payable in Common or in the event the outstanding
shares of Common shall be subdivided, by reclassification or otherwise than by
payment of a dividend in Common, into a greater number of shares of Common, the
Conversion Price in effect immediately prior to such dividend or subdivision
shall be proportionately decreased:


                         (a)  in the case of any such dividend, immediately
after the close of business on the record date for the determination of holders
of any class of securities entitled to receive such dividend, or

                         (b)  in the case of any such subdivision, at the close
of business on the date immediately prior to the date upon which such corporate
action becomes effective.



                                      -4-
<PAGE>   5
     If such record date shall have been fixed and such dividend shall not have
been fully paid on the date fixed therefor, the adjustment previously made in
the Conversion Price which became effective on such record date shall be
canceled as of the close of business on such record date, and thereafter the
Conversion Price shall be adjusted as of the time of actual payment of such
dividend.

          d.   Adjustments for Other Reclassifications, Dividends and
Distributions. If there occurs any capital reorganization or any
reclassification of the capital stock of the Corporation (other than a
subdivision, dividend, combination, consolidation or other transaction provided
for in Section 2 or Section 4 (c)), each share of Series A Preferred shall
thereafter be convertible into the same kind and amounts of securities or other
assets, or both, that were issuable or distributable to the holders of shares of
outstanding Common upon such reorganization or reclassification, in respect of
that number of shares of Common into which such shares of Series A Preferred
might have been converted immediately prior to such reorganization or
reclassification: and in any such case, appropriate adjustments (as determined
by the Board of Directors) shall be made in the application of the provisions
herein set forth with respect to the rights and interests thereafter of the
holders of Series A Preferred to the end that the provisions of these Articles
shall thereafter be applicable, as nearly as reasonably may be, in relation to
any securities or other assets thereafter deliverable upon the conversion of the
Series A Preferred.

          e.   Certificate as to Adjustments. Upon the occurrence of each
adjustment or readjustment of the Conversion Price pursuant to this Section 4,
the corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and furnish to each holder of
Series A Preferred a certificate setting forth such adjustment or readjustment
and showing in detail the facts upon which such adjustment or readjustment is
based. The corporation shall, upon the written request at any time of any holder
of Series A Preferred, furnish or cause to be furnished to such holder a like
certificate setting forth (i) such adjustments and readjustments, (ii) the
Conversion Price at the time in effect, and (iii) the number of shares of Common
and the amount, if any, of other property which at the time would be received
upon the conversion of Series A Preferred.

          f.   Notices of Record Date. In the event that this corporation shall
propose at any time:

               (1)  to declare any dividend or distribution upon its Common
Shares, whether in cash, property, stock or other securities, whether or not a
regular cash dividend and whether or not out of earnings or earned surplus;


                                      -5-
<PAGE>   6
               (2)  to offer for subscription pro rata to the holders of any
class or series of its stock any additional shares of stock of any class or
series or other rights;


               (3)  to effect any reclassification or recapitalization of its
Common Shares outstanding involving a change in the Common Shares; or

               (4)  to merge or consolidate with or into any other corporation,
or sell, lease or convey all or substantially all its property or business, or
to liquidate, dissolve or wind up; then, in connection with each such event,
this corporation shall send to the holders of the Series A Preferred shares:

                    (a)  at least 10 days' prior written notice of the date on
which a record shall be taken for such dividend, distribution or subscription
rights (and specifying the date on which the holders of Common Shares shall be
entitled thereto) or for determining rights to vote in respect of the matters
referred to in (3) and (4) above; and

                    (b)  in the case of the matters referred to in (3) and (4)
above, at least 10 days' prior written notice of the date when the same shall
take place (and specifying, if practicable, or estimating the date on which the
holders of Common Shares shall be entitled to exchange their Common Shares for
securities or other property deliverable upon the occurrence of such event).

     Each such written notice shall be given by first class mail, postage
prepaid, addressed to the holders of Series A Preferred at the address for each
such holder as shown on the books of this corporation.

          g.   Common Stock Reserved.  The corporation shall at all times
reserve and keep available out of its authorized but unissued shares of Common,
solely for the purpose of effecting the conversion of the shares of Series A
Preferred, such number of shares of Common as shall from time to time be
sufficient to effect the conversion of all outstanding shares of the Series A
Preferred, and if at any time the number of authorized but unissued shares of
Common shall not be sufficient to effect the conversion of all then outstanding
shares of the Series A Preferred, the corporation shall take such corporate
action as may, in the opinion of its counsel, be necessary to increase its
authorized but unissued shares of Common to such number of shares as shall be
sufficient for such purpose.

     5.   Voting Rights.  Except as otherwise required by law, each share of
Common issued and outstanding shall have one vote, each share of Series A
Preferred issued and outstanding shall have the number of votes equal to the
number of Common Shares into which such share of Series A Preferred is
convertible as adjusted from time to time pursuant to Section 4 hereof and the
Common and the Series A Preferred shall vote together as a


                                      -6-

<PAGE>   7
single class. Fractional votes by the holders of Series A Preferred shall not,
however, be permitted and any fractional voting rights resulting from the above
formula (after aggregating all shares into which shares of Series A Preferred
held by each holder could be converted) shall be rounded to the nearest whole
number.

     6.   Protective Provisions.

     a.   Subject to the rights of series of Preferred which may from time to
time come into existence, so long as shares of Series A Preferred are
outstanding, this corporation shall not, without first obtaining the approval
(by vote or written consent, as provided by law) of the holders of at least a
majority of the then outstanding shares of Series A Preferred:

          (1)  alter or change the rights, preference or privileges of the
shares of Series A Preferred so as to adversely affect the Series A Preferred;
provided that the issuance of additional preferred stock of the corporation with
rights pari passu to the Series A Preferred shall not be deeded to have such an
adverse effect;

          (2)  issue any new securities of the corporation having a preference
over the Series A Preferred upon liquidation;

          (3)  amend the corporation's Articles of Incorporation or Bylaws in a
way so as to adversely affect the rights of the Series A Preferred; provided
that the issuance of additional preferred stock of the corporation with rights
pari passu to the Series A Preferred shall not be deemed to have such an adverse
effect; or

          (4)  redeem any of the shares of Common or Series A Preferred (except
for repurchases of Common pursuant to the Corporation's repurchase rights in
connection with an employee's or consultant's termination of employment or
engagement, or pursuant to rights of first refusal in favor of the corporation).

     b.   Subject to the rights of series of Preferred which may from time to
time come into existence, so long as shares of Preferred are outstanding, this
corporation shall not, without first obtaining the approval (by vote or written
consent, as provided by law) of the holders of at least a majority of the then
outstanding shares of Preferred:

          (1)  sell, convey or otherwise dispose of all or substantially all of
its assets or business or merge into or consolidate with any other corporation
(other than a wholly-owned subsidiary corporation).

     7.   Status of Converted Stock.  In the event any shares of Series A
Preferred shall be converted pursuant to Section 4 hereof, the shares so
converted shall be cancelled and shall not be issuable by the corporation. The
Articles of


                                      -7-

<PAGE>   8

                          CERTIFICATE OF INCORPORATION
                                       OF
                               ALANEX CORPORATION

         The undersigned, a natural person (the "Sole Incorporator"), for the
purpose of organizing a corporation to conduct the business and promote the
purposes hereinafter stated, under the provisions and subject to the
requirements of the laws of the State of Delaware hereby certifies that:

                                       I.

         The name of this corporation is Alanex Corporation.

                                       II.

         The address of the registered office of the corporation in the State of
Delaware is 9 East Loockerman Street, City of Dover, County of Kent, and the
name of the registered agent of the corporation in the State of Delaware at such
address is the National Registered Agents, Inc.

                                      III.

         The purpose of this corporation is to engage in any lawful act or
activity for which a corporation may be organized under the General Corporation
Law of the State of Delaware.

                                       IV.

         A.       This corporation is authorized to issue two classes of stock
to be designated, respectively, "Common Stock" and "Preferred Stock." The total
number of shares which the corporation is authorized to issue is fifty million
(50,000,000) shares, of which forty million (40,000,000) shares shall be
designated Common Stock, each share having a par value of one-tenth of one cent
($.001) and ten million (10,000,000) shares shall be designated Preferred Stock,
each share having a par value of one-tenth of one cent ($.001).

         B.       The Preferred Stock may be issued from time to time in one or
more series. The Board of Directors is hereby authorized, by filing a
certificate (a "Preferred Stock Designation") pursuant to the Delaware General
Corporation Law, to fix or alter from time to time the designation, powers,
preferences and rights of the shares of each such 

                                       1.
<PAGE>   2

series and the qualifications, limitations or restrictions of any wholly
unissued series of Preferred Stock, and to establish from time to time the
number of shares constituting any such series or any of them; and to increase or
decrease the number of shares of any series subsequent to the issuance of shares
of that series, but not below the number of shares of such series then
outstanding. In case the number of shares of any series shall be decreased in
accordance with the foregoing sentence, the shares constituting such decrease
shall resume the status that they had prior to the adoption of the resolution
originally fixing the number of shares of such series.

                                       V.

         For the management of the business and for the conduct of the affairs
of the corporation, and in further definition, limitation and regulation of the
powers of the corporation, of its directors and of its stockholders or any class
thereof, as the case may be, it is further provided that:

         A.

                  1.       The management of the business and the conduct of the
affairs of the corporation shall be vested in its Board of Directors. The number
of directors which shall constitute the whole Board of Directors shall be fixed
exclusively by one or more resolutions adopted by the Board of Directors.

                  2.       Subject to the rights of the holders of any series of
Preferred Stock to elect additional directors under specified circumstances,
following the closing of the initial public offering pursuant to an effective
registration statement under the Securities Act of 1933, as amended (the "1933
Act"), covering the offer and sale of Common Stock to the public (the "Initial
Public Offering"), the directors shall be divided into three classes designated
as Class I, Class II and Class III, respectively. Directors shall be assigned to
each class in accordance with a resolution or resolutions adopted by the Board
of Directors. At the first annual meeting of stockholders following the closing
of the Initial Public Offering, the term of office of the Class I directors
shall expire and Class I directors shall be elected for a full term of three
years. At the second annual meeting of stockholders following the Closing of the
Initial Public Offering, the term of office of the Class II directors shall
expire and Class II directors shall be elected for a full term of three years.
At the third annual meeting of stockholders following the Closing of the Initial
Public Offering, the term of office of the Class III directors shall expire and
Class III directors shall be elected for a full term of three years. At each
succeeding annual meeting of stockholders, directors shall be elected for a full
term of three years to succeed the directors of the class whose terms expire at
such annual meeting.

                                       2.
<PAGE>   3


         Notwithstanding the foregoing provisions of this Article, each director
shall serve until his successor is duly elected and qualified or until his
death, resignation or removal. No decrease in the number of directors
constituting the Board of Directors shall shorten the term of any incumbent
director.

                  3.       Subject to the rights of the holders of any series of
Preferred Stock, the Board of Directors or any individual director may be
removed from office at any time (i) with cause by the affirmative vote of the
holders of a majority of the voting power of all the then-outstanding shares of
voting stock of the corporation, entitled to vote at an election of directors
(the "Voting Stock") or (ii) without cause by the affirmative vote of the
holders of at least sixty-six and two-thirds percent (66-2/3%) of the voting
power of all the then-outstanding shares of the Voting Stock.

                  4.       Subject to the rights of the holders of any series of
Preferred Stock, any vacancies on the Board of Directors resulting from death,
resignation, disqualification, removal or other causes and any newly created
directorships resulting from any increase in the number of directors, shall,
unless the Board of Directors determines by resolution that any such vacancies
or newly created directorships shall be filled by the stockholders, except as
otherwise provided by law, be filled only by the affirmative vote of a majority
of the directors then in office, even though less than a quorum of the Board of
Directors, and not by the stockholders. Any director elected in accordance with
the preceding sentence shall hold office for the remainder of the full term of
the director for which the vacancy was created or occurred and until such
director's successor shall have been elected and qualified.

         B.

                  1.       Subject to paragraph (h) of Section 43 of the Bylaws,
the Bylaws may be altered or amended or new Bylaws adopted by the affirmative
vote of at least sixty-six and two-thirds percent (66-2/3%) of the voting power
of all of the then-outstanding shares of the Voting Stock. The Board of
Directors shall also have the power to adopt, amend, or repeal Bylaws.

                  2.       The directors of the corporation need not be elected
by written ballot unless the Bylaws so provide.

                  3.       No action shall be taken by the stockholders of the
corporation except at an annual or special meeting of stockholders called in
accordance with the Bylaws and following the closing of the Initial Public
Offering no action shall be taken by the stockholders by written consent.

                  4.       Advance notice of stockholder nominations for the
election of directors and of business to be brought by stockholders before any
meeting of the 

                                       3.
<PAGE>   4

stockholders of the corporation shall be given in the manner provided in the
Bylaws of the corporation.

                                      VI.

         A.       A director of the corporation shall not be personally liable
to the corporation or its stockholders for monetary damages for any breach of
fiduciary duty as a director, except for liability (i) for any breach of the
director's duty of loyalty to the corporation or its stockholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law (iii) under Section 174 of the Delaware General
Corporation Law, or (iv) for any transaction from which the director derived an
improper personal benefit. If the Delaware General Corporation Law is amended
after approval by the stockholders of this Article to authorize corporate action
further eliminating or limiting the personal liability of directors, then the
liability of a director shall be eliminated or limited to the fullest extent
permitted by the Delaware General corporation Law, as so amended.

         B.       Any repeal or modification of this Article VI shall be
prospective and shall not affect the rights under this Article VI in effect at
the time of the alleged occurrence of any act or omission to act giving rise to
liability or indemnification.

                                      VII.

         A.       The corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statute, except as provided in paragraph
B. of this Article VII, and all rights conferred upon the stockholders herein
are granted subject to this reservation.

         B.       Notwithstanding any other provisions of this Certificate of
Incorporation or any provision of law which might otherwise permit a lesser vote
or no vote, but in addition to any affirmative vote of the holders of any
particular class or series of the Voting Stock required by law, this Certificate
of Incorporation or any Preferred Stock Designation, the affirmative vote of the
holders of at least sixty-six and two-thirds percent (66-2/3%) of the voting
power of all of the then-outstanding shares of the Voting Stock, voting together
as a single class, shall be required to alter, amend or repeal Articles V, VI,
and VII.

description of the business desired to be brought before the annual meeting and
the reasons for conducting such business at the annual meeting, (ii) the name
and address, as they appear on the corporation's books, of the stockholder
proposing such business, (iii) the class and number of shares of the corporation
which are beneficially owned by the stockholder, (iv) any material interest of
the stockholder in such business and (v) any other information that is required

statement and form of proxy for a stockholder's meeting, stockholders must
provide notice as required by the regulations promulgated under the 1934 Act.
Notwithstanding anything in these Bylaws to the contrary, no business shall be
conducted at any annual meeting except in accordance with the procedures set
forth in this paragraph (b). The chairman of the annual meeting shall, if the
facts warrant, determine and declare at the meeting that business was not
properly brought before the meeting and in accordance 

                                       2.
<PAGE>   6

with the provisions of this paragraph (b), and, if he should so determine, he
shall so declare at the meeting that any such business not properly brought
before the meeting shall not be transacted.

                  (c) Only persons who are nominated in accordance with the
procedures set forth in this paragraph (c) shall be eligible for election as
directors. Nominations of persons for election to the Board of Directors of the
corporation may be made at a meeting of stockholders by or at the direction of
the Board of Directors or by any stockholder of the corporation entitled to vote
in the election of directors at the meeting who complies with the notice
procedures set forth in this paragraph (c). Such nominations, other than those
made by or at the direction of the Board of Directors, shall be made pursuant to
timely notice in writing to the Secretary of the corporation in accordance with
the provisions of paragraph (b) of this Section 5. Such stockholder's notice
shall set forth (i) as to each person, if any, whom the stockholder proposes to
nominate for election or re-election as a director: (A) the name, age, business
address and residence address of such person, (B) the principal occupation or
employment of such person, (C) the class and number of shares of the corporation
which are beneficially owned by such person, (D) a description of all
arrangements or understandings between the stockholder and each nominee and any
other person or persons (naming such person or persons) pursuant to which the
nominations are to be made by the stockholder, and (E) any other information
relating to such person that is required to be disclosed in solicitations of
proxies for election of directors, or is otherwise required, in each case
pursuant to Regulation 14A under the 1934 Act (including without limitation such
person's written consent to being named in the proxy statement, if any, as a
nominee and to serving as a director if elected); and (ii) as to such
stockholder giving notice, the information required to be provided pursuant to
paragraph (b) of this Section 5. At the request of the Board of Directors, any
person nominated by a stockholder for election as a director shall furnish to
the Secretary of the corporation that information required to be set forth in
the stockholder's notice of nomination which pertains to the nominee. No person
shall be eligible for election as a director of the corporation unless nominated
in accordance with the procedures set forth in this paragraph (c). The chairman
of the meeting shall, if the facts warrant, determine and declare at the meeting
that a nomination was not made in accordance with the procedures prescribed by
these Bylaws, and if he should so determine, he shall so declare at the meeting,
and the defective nomination shall be disregarded.

                  (d) For purposes of this Section 5, "public announcement"
shall mean disclosure in a press release reported by the Dow Jones News Service,
Associated Press or comparable national news service or in a document publicly
filed by the corporation with the Securities and Exchange Commission pursuant to
Section 13, 14 or 15(d) of the Exchange Act.

         SECTION 6. SPECIAL MEETINGS.

                  (a) Special meetings of the stockholders of the corporation
may be called, for any purpose or purposes, by (i) the Chairman of the Board of
Directors, (ii) the Chief Executive Officer, (iii) the Board of Directors
pursuant to a resolution adopted by a majority of the total number of authorized
directors (whether or not there exist any vacancies in previously authorized
directorships at the time any such resolution is presented to the Board of
Directors for adoption) or (iv) by the holders of shares entitled to cast not
less than ten percent (10%) of the votes at the meeting, and shall be held at
such place, on such date, and at such time as the Board of Directors, shall fix.

                  (b) If a special meeting is called by any person or persons
other than the Board of Directors, the request shall be in writing, specifying
the general nature of the business proposed to be transacted, and shall be
delivered personally or sent by registered mail or by telegraphic or other
facsimile transmission to the Chairman of the Board of Directors, the Chief
Executive Officer, or the Secretary of the corporation. No business may be
transacted at such special meeting otherwise than specified in such notice. The
Board of Directors shall determine the time and place of such special meeting,
which shall be held not less than thirty-five (35) nor more than one hundred
twenty (120) days after the date of the receipt of the request. Upon
determination of the time and place of the meeting, the officer receiving the
request shall cause notice to be given to the stockholders entitled to vote, in
accordance with the provisions of Section 7 of these Bylaws. If the notice is
not given within sixty (60) days after the receipt of the request, the person or
persons requesting the meeting may set the time and place of the meeting and
give the notice. Nothing contained in this paragraph (b) shall be construed as
limiting, fixing, or affecting the time when a meeting of stockholders called by
action of the Board of Directors may be held.

         SECTION 7. NOTICE OF MEETINGS. Except as otherwise provided by law or
the Certificate of Incorporation, written notice of each meeting of stockholders
shall be given not less than ten (10) nor more than sixty (60) days before the
date of the meeting to each stockholder entitled to vote at such meeting, such
notice to specify the place, date and hour and purpose or purposes of the
meeting. Notice of the time, place and purpose of any meeting of stockholders
may be waived in writing, signed by the person entitled to notice thereof,
either before or after such meeting, and will be waived by any stockholder by
his attendance thereat in person or by proxy, except when the stockholder
attends a meeting for the express purpose of objecting, at the beginning of the
meeting, to the transaction of any business because the meeting is not lawfully
called or convened. Any stockholder so waiving notice of such meeting shall be
bound by the proceedings of any such meeting in all respects as if due notice
thereof had been given.


                                       4.
<PAGE>   8

         SECTION 8. QUORUM. At all meetings of stockholders, except where
otherwise provided by statute or by the Certificate of Incorporation, or by
these Bylaws, the presence, in person or by proxy duly authorized, of the
holders of a majority of the outstanding shares of stock entitled to vote shall
constitute a quorum for the transaction of business. In the absence of a quorum,
any meeting of stockholders may be adjourned, from time to time, either by the
chairman of the meeting or by vote of the holders of a majority of the shares
represented thereat, but no other business shall be transacted at such meeting.
The stockholders present at a duly called or convened meeting, at which a quorum
is present, may continue to transact business until adjournment, notwithstanding
the withdrawal of enough stockholders to leave less than a quorum. Except as
otherwise provided by law, the Certificate of Incorporation or these Bylaws, all
action taken by the holders of a majority of the vote cast, excluding
abstentions, at any meeting at which a quorum is present shall be valid and
binding upon the corporation; provided, however, that directors shall be elected
by a plurality of the votes of the shares present in person or represented by
proxy at the meeting and entitled to vote on the election of directors. Where a
separate vote by a class or classes or series is required, except where
otherwise provided by the statute or by the Certificate of Incorporation or
these Bylaws, a majority of the outstanding shares of such class or classes or
series, present in person or represented by proxy, shall constitute a quorum
entitled to take action with respect to that vote on that matter and, except
where otherwise provided by the statute or by the Certificate of Incorporation
or these Bylaws, the affirmative vote of the majority (plurality, in the case of
the election of directors) of the votes cast, including abstentions, by the
holders of shares of such class or classes or series shall be the act of such
class or classes or series.

         SECTION 9. ADJOURNMENT AND NOTICE OF ADJOURNED MEETINGS. Any meeting of
stockholders, whether annual or special, may be adjourned from time to time
either by the chairman of the meeting or by the vote of a majority of the shares
casting votes, excluding abstentions. When a meeting is adjourned to another
time or place, notice need not be given of the adjourned meeting if the time and
place thereof are announced at the meeting at which the adjournment is taken. At
the adjourned meeting, the corporation may transact any business which might
have been transacted at the original meeting. If the adjournment is for more
than thirty (30) days or if after the adjournment a new record date is fixed for
the adjourned meeting, a notice of the adjourned meeting shall be given to each
stockholder of record entitled to vote at the meeting.

         SECTION 10. VOTING RIGHTS. For the purpose of determining those
stockholders entitled to vote at any meeting of the stockholders, except as
otherwise provided by law, only persons in whose names shares stand on the stock
records of the corporation on the record date, as provided in Section 12 of
these Bylaws, shall be entitled to vote at any meeting of stockholders. Every
person entitled to vote shall have the right to do so either in person or by an
agent or agents authorized by a proxy granted in accordance with 

                                       5.
<PAGE>   9

Delaware law. An agent so appointed need not be a stockholder. No proxy shall be
voted after three (3) years from its date of creation unless the proxy provides
for a longer period.

         SECTION 11. JOINT OWNERS OF STOCK. If shares or other securities having
voting power stand of record in the names of two (2) or more persons, whether
fiduciaries, members of a partnership, joint tenants, tenants in common, tenants
by the entirety, or otherwise, or if two (2) or more persons have the same
fiduciary relationship respecting the same shares, unless the Secretary is given
written notice to the contrary and is furnished with a copy of the instrument or
order appointing them or creating the relationship wherein it is so provided,
their acts with respect to voting shall have the following effect: (a) if only
one (1) votes, his act binds all; (b) if more than one (1) votes, the act of the
majority so voting binds all; (c) if more than one (1) votes, but the vote is
evenly split on any particular matter, each faction may vote the securities in
question proportionally, or may apply to the Delaware Court of Chancery for
relief as provided in the General Corporation Law of Delaware, Section 217(b).
If the instrument filed with the Secretary shows that any such tenancy is held
in unequal interests, a majority or even-split for the purpose of subsection (c)
shall be a majority or even-split in interest.

         SECTION 12. LIST OF STOCKHOLDERS. The Secretary shall prepare and make,
at least ten (10) days before every meeting of stockholders, a complete list of
the stockholders entitled to vote at said meeting, arranged in alphabetical
order, showing the address of each stockholder and the number of shares
registered in the name of each stockholder. Such list shall be open to the
examination of any stockholder, for any purpose germane to the meeting, during
ordinary business hours, for a period of at least ten (10) days prior to the
meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not
specified, at the place where the meeting is to be held. The list shall be
produced and kept at the time and place of meeting during the whole time thereof
and may be inspected by any stockholder who is present.

         SECTION 13. ACTION WITHOUT MEETING.

                  (a) Unless otherwise provided in the Certificate of
Incorporation, any action required by statute to be taken at any annual or
special meeting of the stockholders, or any action which may be taken at any
annual or special meeting of the stockholders, may be taken without a meeting,
without prior notice and without a vote, if a consent in writing, setting forth
the action so taken, shall be signed by the holders of outstanding stock having
not less than the minimum number of votes that would be necessary to authorize
or take such action at a meeting at which all shares entitled to vote thereon
were present and voted.

                  (b) Every written consent shall bear the date of signature of
each stockholder who signs the consent, and no written consent shall be
effective to take the corporate action referred to therein unless, within sixty
(60) days of the earliest dated consent delivered to the corporation in the
manner herein required, written consents signed by a sufficient number of
stockholders to take action are delivered to the corporation by delivery to its
registered office in the State of Delaware, its principal place of business or
an officer or agent of the corporation having custody of the book in which
proceedings of meetings of stockholders are recorded. Delivery made to a
corporation's registered office shall be by hand or by certified or registered
mail, return receipt requested.

                  (c) Prompt notice of the taking of the corporate action
without a meeting by less than unanimous written consent shall be given to those
stockholders who have not consented in writing. If the action which is consented
to is such as would have required the filing of a certificate under any section
of the General Corporation Law of the State of Delaware if such action had been
voted on by stockholders at a meeting thereof, then the certificate filed under
such section shall state, in lieu of any statement required by such section
concerning any vote of stockholders, that written notice and written consent
have been given as provided in Section 228 of the General Corporation Law of
Delaware.

                  (d) Notwithstanding the foregoing, no such action by written
consent may be taken following the closing of the initial public offering
pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "1933 Act"), covering the offer and sale of Common Stock
of the corporation (the "Initial Public Offering").

         SECTION 14. ORGANIZATION.

                  (a) At every meeting of stockholders, the Chairman of the
Board of Directors, or, if a Chairman has not been appointed or is absent, the
President, or, if the President is absent, a chairman of the meeting chosen by a
majority in interest of the stockholders entitled to vote, present in person or
by proxy, shall act as chairman. The Secretary, or, in his absence, an Assistant
Secretary directed to do so by the President, shall act as secretary of the
meeting.

                  (b) The Board of Directors of the corporation shall be
entitled to make such rules or regulations for the conduct of meetings of
stockholders as it shall deem necessary, appropriate or convenient. Subject to
such rules and regulations of the Board of Directors, if any, the chairman of
the meeting shall have the right and authority to prescribe such rules,
regulations and procedures and to do all such acts as, in the judgment of such
chairman, are necessary, appropriate or convenient for the proper conduct of the
meeting, including, without limitation, establishing an agenda or order of
business for the meeting, rules and procedures for maintaining order at the
meeting and the safety of those present, limitations on participation in such
meeting to stockholders of record of the corporation and their duly authorized
and constituted proxies and such other persons as the chairman shall permit,
restrictions on entry to the meeting after the time fixed for the commencement
thereof, limitations on the time allotted to questions or comments by
participants and regulation of the opening and closing of the polls for
balloting on matters which are to be voted on by ballot. Unless and to the
extent determined by the Board of Directors or the chairman of the meeting,
meetings of stockholders shall not be required to be held in accordance with
rules of parliamentary procedure.

                                   ARTICLE IV

                                    DIRECTORS

         SECTION 15. NUMBER AND TERM OF OFFICE. The authorized number of
directors of the corporation shall be fixed in accordance with the Certificate
of Incorporation. Directors need not be stockholders unless so required by the
Certificate of Incorporation. If for any cause, the directors shall not have
been elected at an annual meeting, they may be elected as soon thereafter as
convenient at a special meeting of the stockholders called for that purpose in
the manner provided in these Bylaws.

         SECTION 16. POWERS. The powers of the corporation shall be exercised,
its business conducted and its property controlled by the Board of Directors,
except as may be otherwise provided by statute or by the Certificate of

         SECTION 17. CLASSES OF DIRECTORS. Subject to the rights of the holders
of any series of Preferred Stock to elect additional directors under specified
circumstances, following the closing of the Initial Public Offering, the
directors shall be divided into three classes designated as Class I, Class II
and Class III, respectively. Directors shall be assigned to each class in
accordance with a resolution or resolutions adopted by the Board of Directors.
At the first annual meeting of stockholders following the closing of the Initial
Public Offering, the term of office of the Class I directors shall expire and
Class I directors shall be elected for a full term of three years. At the second
annual meeting of stockholders following the Closing of the Initial Public
Offering, the term of office of the Class II directors shall expire and Class II
directors shall be elected for a full term of three years. At the third annual
meeting of stockholders following the Closing of the Initial Public Offering,
the term of office of the Class III directors shall expire and Class III
directors shall be elected for a full term of three years. At each succeeding
annual meeting of stockholders, directors shall be elected for a full term of
three years to succeed the directors of the class whose terms expire at such
annual meeting.

         Notwithstanding the foregoing provisions of this Article, each director
shall serve until his successor is duly elected and qualified or until his
death, resignation or removal. No decrease in the number of directors
constituting the Board of Directors shall shorten the term of any incumbent
director.

         SECTION 18. VACANCIES. Unless otherwise provided in the Certificate of
Incorporation, any vacancies on the Board of Directors resulting from death,
resignation, disqualification, removal or other causes and any newly created
directorships resulting from any increase in the number of directors, shall
unless the Board of Directors determines by resolution that any such vacancies
or newly created directorships shall be filled by stockholders, be filled only
by the affirmative vote of a majority of the directors then in office, even
though less than a quorum of the Board of Directors. Any director elected in
accordance with the preceding sentence shall hold office for the remainder of
the full term of the director for which the vacancy was created or occurred and
until such director's successor shall have been elected and qualified. A vacancy
in the Board of Directors shall be deemed to exist under this Bylaw in the case
of the death, removal or resignation of any director.

         SECTION 19. RESIGNATION. Any director may resign at any time by
delivering his written resignation to the Secretary, such resignation to specify
whether it will be effective at a particular time, upon receipt by the Secretary
or at the pleasure of the Board of Directors. If no such specification is made,
it shall be deemed effective at the pleasure of the Board of Directors. When one
or more directors shall resign from the Board of Directors, effective at a
future date, a majority of the directors then in office, including those who
have so resigned, shall have power to fill such vacancy or vacancies, the vote
thereon to take effect when such resignation or resignations shall become
effective, and

                                       9.

each Director so chosen shall hold office for the unexpired portion of the term
of the Director whose place shall be vacated and until his successor shall have
been duly elected and qualified

         SECTION 20. REMOVAL. Subject to the rights of the holders of any series
of Preferred Stock, the Board of Directors or any individual director may be
removed from office at any time (i) with cause by the affirmative vote of the
holders of a majority of the voting power of all the then-outstanding shares of
voting stock of the corporation, entitled to vote at an election of directors
(the "Voting Stock") or (ii) without cause by the affirmative vote of the
holders of at least sixty-six and two-thirds percent (66 2/3%) of the voting
power of all the then-outstanding shares of the Voting Stock.

         SECTION 21. MEETINGS.

                  (a) ANNUAL MEETINGS. The annual meeting of the Board of
Directors shall be held immediately before or after the annual meeting of
stockholders and at the place where such meeting is held. No notice of an annual
meeting of the Board of Directors shall be necessary and such meeting shall be
held for the purpose of electing officers and transacting such other business as
may lawfully come before it.

or of any committee thereof, may participate in a meeting by means of conference
telephone or similar communications equipment by means of which all persons
participating in the meeting can hear each other, and participation in a meeting
by such means shall constitute presence in person at such meeting.

                  (e) NOTICE OF MEETINGS. Notice of the time and place of all
special meetings of the Board of Directors shall be orally or in writing, by
telephone, facsimile, telegraph or telex, during normal business hours, at least
twenty-four (24) hours before the date and time of the meeting, or sent in
writing to each director by first class mail, charges prepaid, at least three

meeting may be waived in writing at any time before or after the meeting and
will be waived by any director by attendance thereat, except when the director

lawfully called or convened.

                  (f) WAIVER OF NOTICE. The transaction of all business at any
meeting of the Board of Directors, or any committee thereof, however called or
noticed, or wherever held, shall be as valid as though had at a meeting duly
held after regular call and notice, if a quorum be present and if, either before
or after the meeting, each of the directors not present shall sign a written
waiver of notice. All such waivers shall be filed with the corporate records or
made a part of the minutes of the meeting.

         SECTION 22. QUORUM AND VOTING.

                  (a) Unless the Certificate of Incorporation requires a greater
number and except with respect to indemnification questions arising under
Section 43 hereof, for which a quorum shall be one-third of the exact number of
directors fixed from time to time in accordance with the Certificate of
Incorporation, a quorum of the Board of Directors shall consist of a majority of
the exact number of directors fixed from time to time by the Board of Directors
in accordance with the Certificate of Incorporation; provided, however, at any
meeting whether a quorum be present or otherwise, a majority of the directors
present may adjourn from time to time until the time fixed for the next regular
meeting of the Board of Directors, without notice other than by announcement at
the meeting.

                  (b) At each meeting of the Board of Directors at which a
quorum is present, all questions and business shall be determined by the
affirmative vote of a majority of the directors present, unless a different vote
be required by law, the Certificate of Incorporation or these Bylaws.

         SECTION 23. ACTION WITHOUT MEETING. Unless otherwise restricted by the
Certificate of Incorporation or these Bylaws, any action required or permitted
to be taken at any meeting of the Board of Directors or of any committee thereof
may be taken without a meeting, if all members of the Board of Directors or

writings are filed with the minutes of proceedings of the Board of Directors or
committee.

         SECTION 24. FEES AND COMPENSATION. Directors shall be entitled to such
compensation for their services as may be approved by the Board of Directors,
including, if so approved, by resolution of the Board of Directors, a fixed sum
and expenses of attendance, if any, for attendance at each regular or special

of Directors. Nothing herein 

                                      11.
<PAGE>   15

contained shall be construed to preclude any director from serving the
corporation in any other capacity as an officer, agent, employee, or otherwise
and receiving compensation therefor.

         SECTION 25. COMMITTEES.

                  (a) EXECUTIVE COMMITTEE. The Board of Directors may by
resolution passed by a majority of the whole Board of Directors appoint an
Executive Committee to consist of one (1) or more members of the Board of
Directors. The Executive Committee, to the extent permitted by law and provided
in the resolution of the Board of Directors shall have and may exercise all the
powers and authority of the Board of Directors in the management of the business
and affairs of the corporation, including without limitation the power or
authority to declare a dividend, to authorize the issuance of stock and to adopt
a certificate of ownership and merger, and may authorize the seal of the
corporation to be affixed to all papers which may require it; but no such
committee shall have the power or authority in reference to amending the
Certificate of Incorporation (except that a committee may, to the extent
authorized in the resolution or resolutions providing for the issuance of shares
of stock adopted by the Board of Directors fix the designations and any of the
preferences or rights of such shares relating to dividends, redemption,
dissolution, any distribution of assets of the corporation or the conversion
into, or the exchange of such shares for, shares of any other class or classes
or any other series of the same or any other class or classes of stock of the
corporation or fix the number of shares of any series of stock or authorize the
increase or decrease of the shares of any series), adopting an agreement of
merger or consolidation, recommending to the stockholders the sale, lease or
exchange of all or substantially all of the corporation's property and assets,
recommending to the stockholders a dissolution of the corporation or a
revocation of a dissolution, or amending the bylaws of the corporation.

                  (b) OTHER COMMITTEES. The Board of Directors may, by
resolution passed by a majority of the whole Board of Directors, from time to
time appoint such other committees as may be permitted by law. Such other
committees appointed by the Board of Directors shall consist of one (1) or more
members of the Board of Directors and shall have such powers and perform such
duties as may be prescribed by the resolution or resolutions creating such
committees, but in no event shall such committee have the powers denied to the
Executive Committee in these Bylaws.

                  (c) TERM. Each member of a committee of the Board of Directors
shall serve a term on the committee coexistent with such member's term on the
Board of Directors. The Board of Directors, subject to the provisions of
subsections (a) or (b) of this Bylaw may at any time increase or decrease the
number of members of a committee or terminate the existence of a committee. The
membership of a committee member shall terminate on the date of his death or
voluntary resignation from the committee or from the 



                                      12.
<PAGE>   16

Board of Directors. The Board of Directors may at any time for any reason remove
any individual committee member and the Board of Directors may fill any
committee vacancy created by death, resignation, removal or increase in the
number of members of the committee. The Board of Directors may designate one or
more directors as alternate members of any committee, who may replace any absent
or disqualified member at any meeting of the committee, and, in addition, in the
absence or disqualification of any member of a committee, the member or members
thereof present at any meeting and not disqualified from voting, whether or not
he or they constitute a quorum, may unanimously appoint another member of the
Board of Directors to act at the meeting in the place of any such absent or
disqualified member.

                  (d) MEETINGS. Unless the Board of Directors shall otherwise
provide, regular meetings of the Executive Committee or any other committee
appointed pursuant to this Section 25 shall be held at such times and places as
are determined by the Board of Directors, or by any such committee, and when
notice thereof has been given to each member of such committee, no further
notice of such regular meetings need be given thereafter. Special meetings of
any such committee may be held at any place which has been determined from time
to time by such committee, and may be called by any director who is a member of
such committee, upon written notice to the members of such committee of the time
and place of such special meeting given in the manner provided for the giving of

may, in its discretion, determine the method and designate the signatory officer
or officers, or other person or persons, to execute on behalf of the corporation
any corporate instrument or document, or to sign on behalf of the corporation
the corporate name without limitation, or to enter into contracts on behalf of
the corporation, except where otherwise provided by law or these Bylaws, and

         Unless otherwise specifically determined by the Board of Directors or

documents requiring the corporate seal, and certificates of shares of stock

                                 SHARES OF STOCK

         SECTION 34. FORM AND EXECUTION OF CERTIFICATES. Certificates for the
shares of stock of the corporation shall be in such form as is consistent with
the Certificate of Incorporation and applicable law. Every holder of stock in
the corporation shall be entitled to have a certificate signed by or in the name
of the corporation by the Chairman of the Board of Directors, or the President
or any Vice President and by the Treasurer or Assistant Treasurer or the
Secretary or Assistant Secretary, certifying the number of shares owned by him
in the corporation. Any or all of the signatures on the certificate may be
facsimiles. In case any officer, transfer agent, or registrar who has signed or
whose facsimile signature has been placed upon a certificate shall have ceased
to be such officer, transfer agent, or registrar before such certificate is
issued, it may be issued with the same effect as if he were such officer,
transfer agent, or registrar at the date of issue. Each certificate shall state
upon the face or back thereof, in full or in summary, all of the powers,
designations, preferences, and rights, and the limitations or restrictions of
the shares authorized to be issued or shall, except as otherwise required by
law, set forth on the face or back a statement that the corporation will furnish
without charge to each stockholder who so requests the powers, designations,
preferences and relative, participating, optional, or other special rights of
each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights. Within a reasonable time after
the issuance or transfer of uncertificated stock, the corporation shall send to
the registered owner thereof a written notice containing the information
required to be set forth or stated on certificates pursuant to this section or
otherwise required by law or with respect to this section a statement that the
corporation will furnish without charge to each stockholder who so requests the
powers, designations, preferences and relative participating, optional or other
special rights of each class of stock or series thereof and the qualifications,
limitations or restrictions of such preferences and/or rights. Except as
otherwise expressly provided by law, the rights and obligations of the holders
of certificates representing stock of the same class and series shall be
identical.

         SECTION 35. LOST CERTIFICATES. A new certificate or certificates shall 
be issued in place of any certificate or certificates theretofore issued by the
corporation alleged to have been lost, stolen, or destroyed, upon the making of
an affidavit of that fact by the 

                                      17.
<PAGE>   21
person claiming the certificate of stock to be lost, stolen, or destroyed. The
corporation may require, as a condition precedent to the issuance of a new
certificate or certificates, the owner of such lost, stolen, or destroyed
certificate or certificates, or his legal representative, to advertise the same
in such manner as it shall require or to give the corporation a surety bond in
such form and amount as it may direct as indemnity against any claim that may be
made against the corporation with respect to the certificate alleged to have
been lost, stolen, or destroyed.

         SECTION 36. TRANSFERS.

                  (a) Transfers of record of shares of stock of the corporation
shall be made only upon its books by the holders thereof, in person or by
attorney duly authorized, and upon the surrender of a properly endorsed
certificate or certificates for a like number of shares.

                  (b) The corporation shall have power to enter into and perform
any agreement with any number of stockholders of any one or more classes of
stock of the corporation to restrict the transfer of shares of stock of the
corporation of any one or more classes owned by such stockholders in any manner
not prohibited by the General Corporation Law of Delaware.

         SECTION 37. FIXING RECORD DATES.

                  (a) In order that the corporation may determine the
stockholders entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, the Board of Directors may fix, in advance, a record
date, which record date shall not precede the date upon which the resolution
fixing the record date is adopted by the Board of Directors, and which record
date shall not be more than sixty (60) nor less than ten (10) days before the
date of such meeting. If no record date is fixed by the Board of Directors, the
record date for determining stockholders entitled to notice of or to vote at a
meeting of stockholders shall be at the close of business on the day next
preceding the day on which notice is given, or if notice is waived, at the close
of business on the day next preceding the day on which the meeting is held. A
determination of stockholders of record entitled to notice of or to vote at a
meeting of stockholders shall apply to any adjournment of the meeting; provided,
however, that the Board of Directors may fix a new record date for the adjourned
meeting.

                  (b) Prior to the Initial Public Offering, in order that the
corporation may determine the stockholders entitled to consent to corporate
action in writing without a meeting, the Board of Directors may fix a record
date, which record date shall not precede the date upon which the 

                                      18.
<PAGE>   22
resolution fixing the record date is adopted by the Board of Directors, and
which date shall not be more than 10 days after the date upon which the
resolution fixing the record date is adopted by the Board of Directors. Any
stockholder of record seeking to have the stockholders authorize or take
corporate action by written consent shall, by written notice to the Secretary,
request the Board of Directors to fix a record date. The Board of Directors
shall promptly, but in all events within 10 days after the date on which such a
request is received, adopt a resolution fixing the record date. If no record
date has been fixed by the Board of Directors within 10 days of the date on
which such a request is received, the record date for determining stockholders
entitled to consent to corporate action in writing without a meeting, when no
prior action by the Board of Directors is required by applicable law, shall be
the first date on which a signed written consent setting forth the action taken
or proposed to be taken is delivered to the corporation by delivery to its
registered office in the State of Delaware, its principal place of business or
an officer or agent of the corporation having custody of the book in which
proceedings of meetings of stockholders are recorded. Delivery made to the
corporation's registered office shall be by hand or by certified or registered
mail, return receipt requested. If no record date has been fixed by the Board of
Directors and prior action by the Board of Directors is required by law, the
record date for determining stockholders entitled to consent to corporate action
in writing without a meeting shall be at the close of business on the day on
which the Board of Directors adopts the resolution taking such prior action.

                  (c) In order that the corporation may determine the
stockholders entitled to receive payment of any dividend or other distribution
or allotment of any rights or the stockholders entitled to exercise any rights
in respect of any change, conversion or exchange of stock, or for the purpose of
any other lawful action, the Board of Directors may fix, in advance, a record
date, which record date shall not precede the date upon which the resolution
fixing the record date is adopted, and which record date shall be not more than
sixty (60) days prior to such action. If no record date is fixed, the record
date for determining stockholders for any such purpose shall be at the close of
business on the day on which the Board of Directors adopts the resolution
relating thereto.

         SECTION 38. REGISTERED STOCKHOLDERS. The corporation shall be entitled 
to recognize the exclusive right of a person registered on its books as the
owner of shares to receive dividends, and to vote as such owner, and shall not
be bound to recognize any equitable or other claim to or interest in such share
or shares on the part of any other person whether or not it shall have express
or other notice thereof, except as otherwise provided by the laws of Delaware.

                       OTHER SECURITIES OF THE CORPORATION

         SECTION 39. EXECUTION OF OTHER SECURITIES. All bonds, debentures and 
other corporate securities of the corporation, other than stock certificates
(covered in Section 34), may be signed by the Chairman of the Board of
Directors, the President or any Vice President, or such other person as may be
authorized by the Board of Directors, and the corporate seal impressed thereon
or a facsimile of such seal imprinted thereon and attested by the signature of
the Secretary or an Assistant Secretary, or the Chief Financial Officer or
Treasurer or an Assistant Treasurer; provided, however, that where any such
bond, debenture or other corporate security shall be authenticated by the manual
signature, or where permissible facsimile signature, of a trustee under an
indenture pursuant to which such bond, debenture or other corporate security
shall be issued, the signatures of the persons signing and attesting the
corporate seal on such bond, debenture or other corporate security may be the
imprinted facsimile of the signatures of such persons. Interest coupons
appertaining to any such bond, debenture or other corporate security,
authenticated by a trustee as aforesaid, shall be signed by the Treasurer or an
Assistant Treasurer of the corporation or such other person as may be authorized
by the Board of Directors, or bear imprinted thereon the facsimile signature of
such person. In case any officer who shall have signed or attested any bond,
debenture or other corporate security, or whose facsimile signature shall appear
thereon or on any such interest coupon, shall have ceased to be such officer
before the bond, debenture or other corporate security so signed or attested
shall have been delivered, such bond, debenture or other corporate security
nevertheless may be adopted by the corporation and issued and delivered as
though the person who signed the same or whose facsimile signature shall have
been used thereon had not ceased to be such officer of the corporation.

                                   ARTICLE IX

                                    DIVIDENDS

         SECTION 40. DECLARATION  OF DIVIDENDS.  Dividends upon the capital
stock of the corporation, subject to the provisions of the Certificate of
Incorporation, if any, may be declared by the Board of Directors pursuant to law
at any regular or special meeting. Dividends may be paid in cash, in property,
or in shares of the capital stock, subject to the provisions of the Certificate
of Incorporation.

         SECTION 41. DIVIDEND RESERVE. Before payment of any dividend, there may
be set aside out of any funds of the corporation available for dividends such
sum or sums as the Board of Directors from time to time, in their absolute
discretion, think proper as a reserve or reserves to meet contingencies, or for
equalizing dividends, or for repairing or 

                                      20.
<PAGE>   24
maintaining any property of the corporation, or for such other purpose as the
Board of Directors shall think conducive to the interests of the corporation,
and the Board of Directors may modify or abolish any such reserve in the manner
in which it was created.

                                   ARTICLE XI

                                 INDEMNIFICATION

         SECTION 43. INDEMNIFICATION OF DIRECTORS,  EXECUTIVE OFFICERS,  OTHER 
                     OFFICERS,  EMPLOYEES AND OTHER AGENTS.

                  (a) DIRECTORS AND EXECUTIVE OFFICERS. The corporation shall
indemnify its directors and executive officers (for the purposes of this Article
XI, "executive officers shall have the meaning defined in Rule 3b-7 promulgated
under the 1934 Act) to the fullest extent not prohibited by the Delaware General
Corporation Law; provided, however, that the corporation may modify the extent
of such indemnification by individual contracts with its directors and executive
officers; and, provided, further, that the corporation shall not be required to
indemnify any director or executive officer in connection with any proceeding
(or part thereof) initiated by such person unless (i) such indemnification is
expressly required to be made by law, (ii) the proceeding was authorized by the
Board of Directors of the corporation, (iii) such indemnification is provided by
the corporation, in its sole discretion, pursuant to the powers vested in the
corporation under the Delaware General Corporation Law or (iv) such
indemnification is required to be made under subsection (d).

                  (b) OTHER  OFFICERS,  EMPLOYEES  AND OTHER  AGENTS.  
The corporation shall have power to indemnify its other officers, employees and
other agents as set forth in the Delaware General Corporation Law.

                  (c) EXPENSES. The corporation shall advance to any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative, by reason of the fact that he is or was a director or
executive officer of the corporation, or is or was serving at the request of the
corporation as a director or executive officer of another corporation,
partnership, joint venture, trust or other enterprise, prior to the final
disposition of the proceeding, promptly following request therefor, all expenses
incurred 

                                      21.
<PAGE>   25
by any director or executive officer in connection with such proceeding upon
receipt of an undertaking by or on behalf of such person to repay said amounts
if it should be determined ultimately that such person is not entitled to be
indemnified under this Bylaw or otherwise.

Notwithstanding the foregoing, unless otherwise determined pursuant to paragraph
(e) of this Bylaw, no advance shall be made by the corporation to an executive
officer of the corporation (except by reason of the fact that such executive
officer is or was a director of the corporation in which event this paragraph
shall not apply) in any action, suit or proceeding, whether civil, criminal,
administrative or investigative, if a determination is reasonably and promptly
made (i) by the Board of Directors by a majority vote of a quorum consisting of
directors who were not parties to the proceeding, or (ii) if such quorum is not
obtainable, or, even if obtainable, a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, that the facts known
to the decision-making party at the time such determination is made demonstrate
clearly and convincingly that such person acted in bad faith or in a manner that
such person did not believe to be in or not opposed to the best interests of the
corporation.

                  (d) ENFORCEMENT. Without the necessity of entering into an
express contract, all rights to indemnification and advances to directors and
executive officers under this Bylaw shall be deemed to be contractual rights and
be effective to the same extent and as if provided for in a contract between the
corporation and the director or executive officer. Any right to indemnification
or advances granted by this Bylaw to a director or executive officer shall be
enforceable by or on behalf of the person holding such right in any court of
competent jurisdiction if (i) the claim for indemnification or advances is
denied, in whole or in part, or (ii) no disposition of such claim is made within
ninety (90) days of request therefor. The claimant in such enforcement action,
if successful in whole or in part, also shall be entitled to be paid the expense
of prosecuting his claim. In connection with any claim for indemnification, the
corporation shall be entitled to raise as a defense to any such action that the
claimant has not met the standards of conduct that make it permissible under the
Delaware General Corporation Law for the corporation to indemnify the claimant
for the amount claimed. In connection with any claim by an executive officer of
the corporation (except in any action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that such
executive officer is or was a director of the corporation) for advances, the
corporation shall be entitled to raise a defense as to any such action clear and
convincing evidence that such person acted in bad faith or in a manner that such
person did not believe to be in or not opposed to the best interests of the
corporation, or with respect to any criminal action or proceeding that such
person acted without reasonable cause to believe that his conduct was lawful.
Neither the failure of the corporation (including its Board of Directors,
independent legal counsel or its stockholders) to have made a determination
prior to the commencement of such action that indemnification of the claimant is
proper 

                                      22.
<PAGE>   26
in the circumstances because he has met the applicable standard of conduct set
forth in the Delaware General Corporation Law, nor an actual determination by
the corporation (including its Board of Directors, independent legal counsel or
its stockholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that claimant
has not met the applicable standard of conduct.

                  (e) NON-EXCLUSIVITY OF RIGHTS. The rights conferred on any
person by this Bylaw shall not be exclusive of any other right which such person
may have or hereafter acquire under any statute, provision of the Certificate of
Incorporation, Bylaws, agreement, vote of stockholders or disinterested
directors or otherwise, both as to action in his official capacity and as to
action in another capacity while holding office. The corporation is specifically
authorized to enter into individual contracts with any or all of its directors,
officers, employees or agents respecting indemnification and advances, to the
fullest extent not prohibited by the Delaware General Corporation Law.

                  (f) SURVIVAL OF RIGHTS.  The rights  conferred on any person
by this Bylaw shall continue as to a person who has ceased to be a director,
officer, employee or other agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.

                  (g) INSURANCE.  To the fullest extent  permitted by the 
Delaware General Corporation Law, the corporation, upon approval by the Board of
Directors, may purchase insurance on behalf of any person required or permitted
to be indemnified pursuant to this Bylaw.

                  (h) AMENDMENTS.  Any repeal or  modification  of this Bylaw  
shall only be prospective and shall not affect the rights under this Bylaw in
effect at the time of the alleged occurrence of any action or omission to act
that is the cause of any proceeding against any agent of the corporation.

                  (i) SAVING CLAUSE. If this Bylaw or any portion hereof shall 
be invalidated on any ground by any court of competent jurisdiction, then the
corporation shall nevertheless indemnify each director and executive officer to
the full extent not prohibited by any applicable portion of this Bylaw that
shall not have been invalidated, or by any other applicable law.

                  (j) CERTAIN  DEFINITIONS.  For the purposes of this Bylaw, the
following definitions shall apply:

                                    (i)      The term  "proceeding"  shall be
broadly construed and shall include, without limitation, the investigation,

threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative.

                                    (ii)      The term  "expenses"  shall be  
broadly construed and shall include, without limitation, court costs, attorneys'
fees, witness fees, fines, amounts paid in settlement or judgment and any other
costs and expenses of any nature or kind incurred in connection with any
proceeding.

                                    (iii)      The  term  the  "corporation"   
shall include, in addition to the resulting corporation, any constituent
corporation (including any constituent of a constituent) absorbed in a
consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors, officers, and employees
or agents, so that any person who is or was a director, officer, employee or
agent of such constituent corporation, or is or was serving at the request of
such constituent corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
shall stand in the same position under the provisions of this Bylaw with respect
to the resulting or surviving corporation as he would have with respect to such
constituent corporation if its separate existence had continued.

                                    (iv)      References to a "director,"
"executive officer," "officer," "employee," or "agent" of the corporation shall
include, without limitation, situations where such person is serving at the
request of the corporation as, respectively, a director, executive officer,
officer, employee, trustee or agent of another corporation, partnership, joint
venture, trust or other enterprise.

                                    (v)      References  to  "other enterprises"
shall include employee benefit plans; references to "fines" shall include any
excise taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the corporation" shall include any
service as a director, officer, employee or agent of the corporation which
imposes duties on, or involves services by, such director, officer, employee, or
agent with respect to an employee benefit plan, its participants, or
beneficiaries; and a person who acted in good faith and in a manner he
reasonably believed to be in the interest of the participants and beneficiaries
of an employee benefit plan shall be deemed to have acted in a manner "not
opposed to the best interests of the corporation" as referred to in this Bylaw.

                                     NOTICES

         SECTION 44. NOTICES.

                  (a) NOTICE TO STOCKHOLDERS. Whenever, under any provisions of
these Bylaws, notice is required to be given to any stockholder, it shall be
given in writing, timely and duly deposited in the United States mail, postage
prepaid, and addressed to his last known post office address as shown by the
stock record of the corporation or its transfer agent.

                  (b) NOTICE TO DIRECTORS. Any notice required to be given to 
any director may be given by the method stated in subsection (a), or by
facsimile, telex or telegram, except that such notice other than one which is
delivered personally shall be sent to such address as such director shall have
filed in writing with the Secretary, or, in the absence of such filing, to the
last known post office address of such director.

                  (c) AFFIDAVIT OF MAILING. An affidavit of mailing, executed by
a duly authorized and competent employee of the corporation or its transfer
agent appointed with respect to the class of stock affected, specifying the name
and address or the names and addresses of the stockholder or stockholders, or
director or directors, to whom any such notice or notices was or were given, and
the time and method of giving the same, shall in the absence of fraud, be prima
facie evidence of the facts therein contained.

                  (d) TIME NOTICES DEEMED GIVEN. All notices given by mail, as
above provided, shall be deemed to have been given as at the time of mailing,
and all notices given by facsimile, telex or telegram shall be deemed to have
been given as of the sending time recorded at time of transmission.

                  (e) METHODS OF NOTICE.  It shall not be necessary  that the 
same method of giving notice be employed in respect of all directors, but one
permissible method may be employed in respect of any one or more, and any other
permissible method or methods may be employed in respect of any other or others.

                  (f) FAILURE TO RECEIVE NOTICE. The period or limitation of 
time within which any stockholder may exercise any option or right, or enjoy any
privilege or benefit, or be required to act, or within which any director may
exercise any power or right, or enjoy any privilege, pursuant to any notice sent
him in the manner above provided, shall not be affected or extended in any
manner by the failure of such stockholder or such director to receive such
notice.

                                      25.
<PAGE>   29
                  (g) NOTICE TO PERSON WITH WHOM COMMUNICATION IS UNLAWFUL.
Whenever notice is required to be given, under any provision of law or of the
Certificate of Incorporation or Bylaws of the corporation, to any person with
whom communication is unlawful, the giving of such notice to such person shall
not be required and there shall be no duty to apply to any governmental
authority or agency for a license or permit to give such notice to such person.
Any action or meeting which shall be taken or held without notice to any such
person with whom communication is unlawful shall have the same force and effect
as if such notice had been duly given. In the event that the action taken by the
corporation is such as to require the filing of a certificate under any
provision of the Delaware General Corporation Law, the certificate shall state,
if such is the fact and if notice is required, that notice was given to all
persons entitled to receive notice except such persons with whom communication
is unlawful.

                  (h) NOTICE TO PERSON WITH UNDELIVERABLE ADDRESS. Whenever
notice is required to be given, under any provision of law or the Certificate of
Incorporation or Bylaws of the corporation, to any stockholder to whom (i)
notice of two consecutive annual meetings, and all notices of meetings to such
person during the period between such two consecutive annual meetings, or (ii)
all, and at least two, payments (if sent by first class mail) of dividends or
interest on securities during a twelve-month period, have been mailed addressed
to such person at his address as shown on the records of the corporation and
have been returned undeliverable, the giving of such notice to such person shall
not be required. Any meeting which shall be held without notice to such person
shall have the same force and effect as if such notice had been duly given. If
any such person shall deliver to the corporation a written notice setting forth
his then current address, the requirement that notice be given to such person
shall be reinstated. In the event that the action taken by the corporation is
such as to require the filing of a certificate under any provision of the
Delaware General Corporation Law, the certificate need not state that notice was
not given to persons to whom notice was not required to be given pursuant to
this paragraph.

                                  ARTICLE XIII

                                   AMENDMENTS

         SECTION 45. AMENDMENTS

         Subject to paragraph (h) of Section 43 of the Bylaws, the Bylaws may be
altered or amended or new Bylaws adopted by the affirmative vote of at least
sixty-six and two-thirds percent (66-2/3%) of the voting power of all of the
then-outstanding shares of the Voting Stock. The Board of Directors shall also
have the power to adopt, amend, or repeal Bylaws.

                                LOANS TO OFFICERS

         SECTION 46. LOANS TO OFFICERS. The corporation may lend money to, or
guarantee any obligation of, or otherwise assist any officer or other employee
of the corporation or of its subsidiaries, including any officer or employee who
is a Director of the corporation or its subsidiaries, whenever, in the judgment
of the Board of Directors, such loan, guarantee or assistance may reasonably be
expected to benefit the corporation. The loan, guarantee or other assistance may
be with or without interest and may be unsecured, or secured in such manner as
the Board of Directors shall approve, including, without limitation, a pledge of
shares of stock of the corporation. Nothing in these Bylaws shall be deemed to
deny, limit or restrict the powers of guaranty or warranty of the corporation at
common law or under any statute.

                                   ARTICLE XV

                                  MISCELLANEOUS

         SECTION 47. ANNUAL REPORT.

                  (a) Subject to the provisions of paragraph (b) of this Bylaw,
the Board of Directors shall cause an annual report to be sent to each
stockholder of the corporation not later than one hundred twenty (120) days
after the close of the corporation's fiscal year. Such report shall include a
balance sheet as of the end of such fiscal year and an income statement and
statement of changes in financial position for such fiscal year, accompanied by
any report thereon of independent accounts or, if there is no such report, the
certificate of an authorized officer of the corporation that such statements
were prepared without audit from the books and records of the corporation. When
there are more than 100 stockholders of record of the corporation's shares, as
determined by Section 605 of the California Corporations Code, additional
information as required by Section 1501(b) of the California Corporations Code
shall also be contained in such report, provided that if the corporation has a
class of securities registered under Section 12 of the 1934 Act, that Act shall
take precedence. Such report shall be sent to stockholders at least fifteen (15)
days prior to the next annual meeting of stockholders after the end of the
fiscal year to which it relates.

                  (b) If and so long as there are fewer than 100 holders of
record of the corporation's shares, the requirement of sending of an annual
report to the stockholders of the corporation is hereby expressly waived.

                                      27.

                               INDEMNITY AGREEMENT

         THIS AGREEMENT is made and entered into this ____ day of ___________,
1996 by and between ALANEX CORPORATION, a Delaware corporation (the 
"Corporation"), and _____________ ("Agent").

                                    RECITALS

         WHEREAS, Agent performs a valuable service to the Corporation in his
capacity as a director of the Corporation;

         WHEREAS, the stockholders of the Corporation have adopted bylaws (the
"Bylaws") providing for the indemnification of the directors, officers,
employees and other agents of the Corporation, including persons serving at the
request of the Corporation in such capacities with other corporations or
enterprises, as authorized by the Delaware General Corporation Law, as amended
(the "Code");

         WHEREAS, the Bylaws and the Code, by their non-exclusive nature, permit
contracts between the Corporation and its agents, officers, employees and other
agents with respect to indemnification of such persons; and

         WHEREAS, in order to induce Agent to continue to serve as a director of
the Corporation, the Corporation has determined and agreed to enter into this
Agreement with Agent;

         NOW, THEREFORE, in consideration of Agent's continued service as a
director after the date hereof, the parties hereto agree as follows:

                                    AGREEMENT

         1.       SERVICES TO THE CORPORATION. Agent will serve, at the will of
the Corporation or under separate contract, if any such contract exists, as a
director of the Corporation or as a director, officer or other fiduciary of an
affiliate of the Corporation (including any employee benefit plan of the
Corporation) faithfully and to the best of his ability so long as he is duly
elected and qualified in accordance with the provisions of the Bylaws or other
applicable charter documents of the Corporation or such affiliate; provided,
however, that Agent may at any time and for any reason resign from such position
(subject to any contractual obligation that Agent may have assumed apart from
this Agreement) and that the Corporation or any affiliate shall have no
obligation under this Agreement to continue Agent in any such position.

                                       1.
<PAGE>   2
         2.       INDEMNITY OF AGENT. The Corporation hereby agrees to hold
harmless and indemnify Agent to the fullest extent authorized or permitted by
the provisions of the Bylaws and the Code, as the same may be amended from time
to time (but, only to the extent that such amendment permits the Corporation to
provide broader indemnification rights than the Bylaws or the Code permitted
prior to adoption of such amendment).

         3.       ADDITIONAL INDEMNITY. In addition to and not in limitation of
the indemnification otherwise provided for herein, and subject only to the
exclusions set forth in Section 4 hereof, the Corporation hereby further agrees
to hold harmless and indemnify Agent:

                  (a)      against any and all expenses (including attorneys'
fees), witness fees, damages, judgments, fines and amounts paid in settlement
and any other amounts that Agent becomes legally obligated to pay because of any
claim or claims made against or by him in connection with any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
arbitrational, administrative or investigative (including an action by or in the
right of the Corporation) to which Agent is, was or at any time becomes a party,
or is threatened to be made a party, by reason of the fact that Agent is, was or
at any time becomes a director, officer, employee or other agent of Corporation,
or is or was serving or at any time serves at the request of the Corporation as
a director, officer, employee or other agent of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise;
and

                  (b)      otherwise to the fullest extent as may be provided to
Agent by the Corporation under the non-exclusivity provisions of the Code and
Section 43 of the Bylaws.

         4.       LIMITATIONS ON ADDITIONAL INDEMNITY. No indemnity pursuant to
Section 3 hereof shall be paid by the Corporation:

                  (a)      on account of any claim against Agent for an
accounting of profits made from the purchase or sale by Agent of securities of
the Corporation pursuant to the provisions of Section 16(b) of the Securities
Exchange Act of 1934 and amendments thereto or similar provisions of any
federal, state or local statutory law;

                  (b)      on account of Agent's conduct that was knowingly
fraudulent or deliberately dishonest or that constituted willful misconduct;

                  (c)      on account of Agent's conduct that constituted a
breach of Agent's duty of loyalty to the Corporation or resulted in any personal
profit or advantage to which Agent was not legally entitled;

                                       2.
<PAGE>   3
                  (d)      for which payment is actually made to Agent under a
valid and collectible insurance policy or under a valid and enforceable
indemnity clause, bylaw or agreement, except in respect of any excess beyond
payment under such insurance, clause, bylaw or agreement;

                  (e)      if indemnification is not lawful (and, in this
respect, both the Corporation and Agent have been advised that the Securities
and Exchange Commission believes that indemnification for liabilities arising
under the federal securities laws is against public policy and is, therefore,
unenforceable and that claims for indemnification should be submitted to
appropriate courts for adjudication); or

                  (f)      in connection with any proceeding (or part thereof)
initiated by Agent, or any proceeding by Agent against the Corporation or its
directors, officers, employees or other agents, unless (i) such indemnification
is expressly required to be made by law, (ii) the proceeding was authorized by
the Board of Directors of the Corporation, (iii) such indemnification is
provided by the Corporation, in its sole discretion, pursuant to the powers
vested in the Corporation under the Code, or (iv) the proceeding is initiated
pursuant to Section 9 hereof.

         5.       CONTINUATION OF INDEMNITY. All agreements and obligations of
the Corporation contained herein shall continue during the period Agent is a
director, officer, employee or other agent of the Corporation (or is or was
serving at the request of the Corporation as a director, officer, employee or
other agent of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise) and shall continue thereafter so long as Agent
shall be subject to any possible claim or threatened, pending or completed
action, suit or proceeding, whether civil, criminal, arbitrational,
administrative or investigative, by reason of the fact that Agent was serving in
the capacity referred to herein.

         6.       PARTIAL INDEMNIFICATION. Agent shall be entitled under this
Agreement to indemnification by the Corporation for a portion of the expenses
(including attorneys' fees), witness fees, damages, judgments, fines and amounts
paid in settlement and any other amounts that Agent becomes legally obligated to
pay in connection with any action, suit or proceeding referred to in Section 3
hereof even if not entitled hereunder to indemnification for the total amount
thereof, and the Corporation shall indemnify Agent for the portion thereof to
which Agent is entitled.

         7.       NOTIFICATION AND DEFENSE OF CLAIM. Not later than thirty (30)
days after receipt by Agent of notice of the commencement of any action, suit or
proceeding, Agent will, if a claim in respect thereof is to be made against the
Corporation under this Agreement, notify the Corporation of the commencement
thereof; but the omission so to notify the Corporation will not relieve it from
any liability which it may have to Agent 

                                       3.
<PAGE>   4
otherwise than under this Agreement. With respect to any such action, suit or
proceeding as to which Agent notifies the Corporation of the commencement
thereof:

                  (a)      the Corporation will be entitled to participate
therein at its own expense;

                  (b)      except as otherwise provided below, the Corporation
may, at its option and jointly with any other indemnifying party similarly
notified and electing to assume such defense, assume the defense thereof, with
counsel reasonably satisfactory to Agent. After notice from the Corporation to
Agent of its election to assume the defense thereof, the Corporation will not be
liable to Agent under this Agreement for any legal or other expenses
subsequently incurred by Agent in connection with the defense thereof except for
reasonable costs of investigation or otherwise as provided below. Agent shall
have the right to employ separate counsel in such action, suit or proceeding but
the fees and expenses of such counsel incurred after notice from the Corporation
of its assumption of the defense thereof shall be at the expense of Agent unless
(i) the employment of counsel by Agent has been authorized by the Corporation,
(ii) Agent shall have reasonably concluded that there may be a conflict of
interest between the Corporation and Agent in the conduct of the defense of such
action or (iii) the Corporation shall not in fact have employed counsel to
assume the defense of such action, in each of which cases the fees and expenses
of Agent's separate counsel shall be at the expense of the Corporation. The
Corporation shall not be entitled to assume the defense of any action, suit or
proceeding brought by or on behalf of the Corporation or as to which Agent shall
have made the conclusion provided for in clause (ii) above; and

                  (c)      the Corporation shall not be liable to indemnify
Agent under this Agreement for any amounts paid in settlement of any action or
claim effected without its written consent, which shall not be unreasonably
withheld. The Corporation shall be permitted to settle any action except that it
shall not settle any action or claim in any manner which would impose any
penalty or limitation on Agent without Agent's written consent, which may be
given or withheld in Agent's sole discretion.

         8.       EXPENSES. The Corporation shall advance, prior to the final
disposition of any proceeding, promptly following request therefor, all expenses
incurred by Agent in connection with such proceeding upon receipt of an
undertaking by or on behalf of Agent to repay said amounts if it shall be
determined ultimately that Agent is not entitled to be indemnified under the
provisions of this Agreement, the Bylaws, the Code or otherwise.

         9.       ENFORCEMENT. Any right to indemnification or advances granted
by this Agreement to Agent shall be enforceable by or on behalf of Agent in any
court of competent jurisdiction if (i) the claim for indemnification or advances
is denied, in whole or in part, or (ii) no disposition of such claim is made
within ninety (90) days of request 

                                       4.
<PAGE>   5
therefor. Agent, in such enforcement action, if successful in whole or in part,
shall be entitled to be paid also the expense of prosecuting his claim. It shall
be a defense to any action for which a claim for indemnification is made under
Section 3 hereof (other than an action brought to enforce a claim for expenses
pursuant to Section 8 hereof, provided that the required undertaking has been
tendered to the Corporation) that Agent is not entitled to indemnification
because of the limitations set forth in Section 4 hereof. Neither the failure of
the Corporation (including its Board of Directors or its stockholders) to have
made a determination prior to the commencement of such enforcement action that
indemnification of Agent is proper in the circumstances, nor an actual
determination by the Corporation (including its Board of Directors or its
stockholders) that such indemnification is improper shall be a defense to the
action or create a presumption that Agent is not entitled to indemnification
under this Agreement or otherwise.

         10.      SUBROGATION. In the event of payment under this Agreement, the
Corporation shall be subrogated to the extent of such payment to all of the
rights of recovery of Agent, who shall execute all documents required and shall
do all acts that may be necessary to secure such rights and to enable the
Corporation effectively to bring suit to enforce such rights.

         11.      NON-EXCLUSIVITY OF RIGHTS. The rights conferred on Agent by
this Agreement shall not be exclusive of any other right which Agent may have or
hereafter acquire under any statute, provision of the Corporation's Certificate
of Incorporation or Bylaws, agreement, vote of stockholders or directors, or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding office.

         12.      SURVIVAL OF RIGHTS.

                  (a)      The rights conferred on Agent by this Agreement shall
continue after Agent has ceased to be a director, officer, employee or other
agent of the Corporation or to serve at the request of the Corporation as a
director, officer, employee or other agent of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise and shall inure
to the benefit of Agent's heirs, executors and administrators.

                  (b)      The Corporation shall require any successor (whether
direct or indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business or assets of the Corporation, expressly to
assume and agree to perform this Agreement in the same manner and to the same
extent that the Corporation would be required to perform if no such succession
had taken place.

         13.      SEPARABILITY. Each of the provisions of this Agreement is a
separate and distinct agreement and independent of the others, so that if any
provision hereof shall be held to be invalid for any reason, such invalidity or
unenforceability shall not affect the 

                                       5.
<PAGE>   6
validity or enforceability of the other provisions hereof. Furthermore, if this
Agreement shall be invalidated in its entirety on any ground, then the
Corporation shall nevertheless indemnify Agent to the fullest extent provided by
the Bylaws, the Code or any other applicable law.

         14.      ENTIRE AGREEMENT. This Agreement and the agreements referenced
herein constitute the entire agreement between the parties hereto pertaining to
the subject matter hereof, and any and all other written or oral agreements
existing between the parties hereto pertaining to the subject matters hereof are
superseded and expressly canceled.

         15.      GOVERNING LAW. This Agreement shall be interpreted and
enforced in accordance with the laws of the State of Delaware.

         16.      AMENDMENT AND TERMINATION. No amendment, modification,
termination or cancellation of this Agreement shall be effective unless in
writing signed by both parties hereto.

         17.      IDENTICAL COUNTERPARTS. This Agreement may be executed in one
or more counterparts, each of which shall for all purposes be deemed to be an
original but all of which together shall constitute but one and the same
Agreement. Only one such counterpart need be produced to evidence the existence
of this Agreement.

         18.      HEADINGS. The headings of the sections of this Agreement are
inserted for convenience only and shall not be deemed to constitute part of this
Agreement or to affect the construction hereof.

         19.      NOTICES. All notices, requests, demands and other
communications hereunder shall be in writing and shall be deemed to have been
duly given (i) upon delivery if delivered by hand to the party to whom such
communication was directed or (ii) upon the third business day after the date on
which such communication was mailed if mailed by certified or registered mail
with postage prepaid:

         (b) The Board shall have the power, subject to, and within the 
limitations of, the express provisions of the Plan:

                  (1) To determine from time to time which of the persons
eligible under the Plan shall be granted Stock Awards; when and how each Stock
Award shall be granted; whether a Stock Award will be an Incentive Stock Option,
a Nonstatutory Stock Option, a stock bonus, a right to purchase restricted
stock, or a combination of the foregoing; the provisions of each Stock Award
granted (which need not be identical), including the time or times when a person

                  (2) To construe and interpret the Plan and Stock Awards
granted under it, and to establish, amend and revoke rules and regulations for
its administration. The Board, in the exercise of this power, may correct any
defect, omission or inconsistency in the Plan or in any Stock Award Agreement,
in a manner and to the extent it shall deem necessary or expedient to make the
Plan fully effective.

                  (3) To amend the Plan or a Stock Award as provided in Section

                  (4) Generally, to exercise such powers and to perform such

to delegate to a subcommittee of two (2) or more Outside Directors any of the
administrative powers the Committee is authorized to exercise (and references in
this Plan to the Board shall thereafter be to the Committee or such a
subcommittee), subject, however, to such resolutions, not inconsistent with the
provisions of the Plan, as may be adopted from time to time by the Board. The
Board may abolish the Committee at any time and revest in the


                                       4.
<PAGE>   5
Board the administration of the Plan. Notwithstanding anything in this Section 3
to the contrary, at any time the Board or the Committee may delegate to a
committee of one or more members of the Board the authority to grant Stock
Awards to eligible persons who (1) are not then subject to Section 16 of the

expected to be Covered Employees at the time of recognition of income resulting

         (d) Any requirement that an administrator of the Plan be a Non-Employee
Director shall not apply (i) prior to the date of the first registration of an
equity security of the Company under Section 12 of the Exchange Act, or (ii) if

apply. Any Non-Employee Director shall otherwise comply with the requirements of
Rule 16b-3.

4.       SHARES SUBJECT TO THE PLAN.

         (a) Subject to the provisions of Section 12 relating to adjustments
upon changes in stock, the stock that may be issued pursuant to Stock Awards
granted under the Plan shall not exceed in the aggregate five hundred thousand
(500,000) shares of the Company's common stock. If any Stock Award granted under
the Plan shall for any reason expire or otherwise terminate, in whole or in
part, without having been exercised in full, the stock not acquired under such
Stock Award shall revert to and again become available for issuance under the
Plan.

         (b) The stock subject to the Plan may be unissued shares or reacquired
shares, bought on the market or otherwise.

5.       ELIGIBILITY.

         (a) Incentive Stock Options may be granted only to Employees. Stock
Awards other than Incentive Stock Options may be granted only to Employees,
Directors or Consultants. Notwithstanding the foregoing, no Stock Awards shall
be granted to a Director (including a Director who is an Employee or a
Consultant) between (i) the date of the first registration of an equity security
of the Company under Section 12 of the Exchange Act, and (ii) August 15, 1996
(or such later date as the amendments to Rule 16b-3 adopted by the Securities
and Exchange Commission pursuant to Release No. 34-37260 become effective as to
the Company), unless such Director is expressly declared eligible to participate
in the Plan by action of the Board or the Committee.

         (b) No person shall be eligible for the grant of an Incentive Stock
Option if, at the time of grant, such person owns (or is deemed to own pursuant
to Section 424(d) of the Code) stock possessing more than ten percent (10%) of
the total combined voting power of all classes of stock of the Company or of any
of its Affiliates unless the exercise price of such Option is at least one
hundred ten percent (110%) of the Fair Market Value of such stock at the date of
grant and the Option is not exercisable after the expiration of five (5) years
from the date of grant. Prior to the date of the first registration of an equity
security of the Company under


                                       5.
<PAGE>   6
Section 12 of the Exchange Act, the provisions of this subsection 5(b) shall
also apply to the grant of a Nonstatutory Stock Option made to a ten percent
(10%) stockholder as described in the preceding sentence.

         (c) Subject to the provisions of Section 12 (relating to adjustments
upon changes in stock) no person shall be eligible to be granted Options
covering more than three hundred seventy-five thousand (375,000) shares of the
Company's common stock in any calendar year. This subsection 5(c) shall not
apply prior to the date of the first registration of an equity security of the
Company under Section 12 of the Exchange Act and, following such registration,
shall not apply until (i) the earliest of: (A) the first material modification
of the Plan (including any increase to the number of shares reserved for
issuance under the Plan in accordance with Section 4); (B) the issuance of all
of the shares of common stock reserved for issuance under the Plan; (C) the
expiration of the Plan; or (D) the first meeting of stockholders at which
directors are to be elected that occurs after the close of the third calendar
year following the calendar year in which occurred the first registration of an
equity security under Section 12 of the Exchange Act; or (ii) such other date
required by Section 162(m) of the Code and the rules and regulations promulgated
thereunder.

6.       OPTION PROVISIONS.

         Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. The provisions of separate
Options need not be identical, but each Option shall include (through
incorporation of provisions hereof by reference in the Option or otherwise) the
substance of each of the following provisions:

         (a) TERM.  No Option shall be exercisable after the expiration of ten 
(10) years from the date it was granted.

         (b) PRICE. The exercise price of each Incentive Stock Option shall be
not less than one hundred percent (100%) of the Fair Market Value of the stock
subject to the Option on the date the Option is granted. The exercise price of
each Nonstatutory Stock Option shall be determined by the Board or the
Committee. Notwithstanding the foregoing sentence, the exercise price of each
Nonstatutory Stock Option granted prior to the date of the first registration of
an equity security of the Company under Section 12 of the Exchange Act shall be
not less than eighty-five percent (85%) of the Fair Market Value of the stock
subject to the Option on the date the Option is granted. Notwithstanding the
foregoing, an Option may be granted with an exercise price lower than that set
forth above if such Option is granted pursuant to an assumption or substitution
for another option in a manner satisfying the provisions of Section 424(a) of
the Code.

         (c) CONSIDERATION. The purchase price of stock acquired pursuant to an
Option shall be paid, to the extent permitted by applicable statutes and
regulations, either (i) in cash at the time the Option is exercised, or (ii) at
the discretion of the Board or the Committee, at the time of the grant of the
Option, (A) by delivery to the Company of other common stock of the Company, (B)
according to a deferred payment or other arrangement (which may include,


                                       6.
<PAGE>   7
without limiting the generality of the foregoing, the use of other common stock
of the Company) with the person to whom the Option is granted or to whom the
Option is transferred pursuant to subsection 6(d), or (C) in any other form of
legal consideration that may be acceptable to the Board.

         In the case of any deferred payment arrangement, 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 amounts other than amounts stated to be interest under the
deferred payment arrangement.

         (d) TRANSFERABILITY. An Option shall not be transferable except by will
or by the laws of descent and distribution, and shall be exercisable during the
lifetime of the person to whom the Option is granted only by such person, except
that, after the date of the first registration of an equity security of the
Company under Section 12 of the Exchange Act, a Nonstatutory Stock Option may be
transferred by the Optionee upon such terms and conditions as are set forth in
the Option Agreement for such Nonstatutory Option, as the Board or the Committee
shall determine in its discretion, including (without limitation) pursuant to a
"domestic relations order" within the meaning of such rules, regulations or
interpretations of the Securities and Exchange Commission as are applicable for
purposes of Section 16 of the Exchange Act (a "DRO"). In the event of a transfer
of a Nonstatutory Option as provided in the Option Agreement, the transferee
shall be entitled to exercise such Nonstatutory Option to the extent of his or
her interest received in such transfer, subject to the terms and conditions of
the Option Agreement. Notwithstanding the foregoing, the person to whom an
Option is granted may, by delivering written notice to the Company, in a form
satisfactory to the Company, designate a third party who, in the event of the
death of the Optionee, shall thereafter be entitled to exercise the Option.

         (e) VESTING. The total number of shares of stock subject to an Option
may, but need not, be allotted in periodic installments (which may, but need
not, be equal). The Option Agreement may provide that from time to time during
each of such installment periods, the Option may become exercisable ("vest")
with respect to some or all of the shares allotted to that period, and may be
exercised with respect to some or all of the shares allotted to such period
and/or any prior period as to which the Option became vested but was not fully
exercised. The Option may be subject to such other terms and conditions on the
time or times when it may be exercised (which may be based on performance or
other criteria) as the Board may deem appropriate. The vesting provisions of
individual options may vary; provided, however, that Options granted prior to
the date of the first registration of an equity security of the Company under
Section 12 of the Exchange Act will in each case provide for vesting of at least
twenty percent (20%) per year of the total number of shares subject to the
Option. The provisions of this subsection 6(e) are subject to any Option
provisions governing the minimum number of shares as to which an Option may be
exercised.

         (f) TERMINATION OF EMPLOYMENT OR RELATIONSHIP AS A DIRECTOR OR 
CONSULTANT. In the event an Optionee's Continuous Status as an Employee,
Director or Consultant terminates (other than upon the Optionee's death or
disability), the Optionee may exercise his or her Option


                                       7.
<PAGE>   8
(to the extent that the Optionee was entitled to exercise it at the date of
termination) but only within such period of time ending on the earlier of (i)
the date three (3) months after the termination of the Optionee's Continuous
Status as an Employee, Director or Consultant (or such longer or shorter period
specified in the Option Agreement, which period shall be no less than thirty
(30) days for Options granted prior to the date of the first registration of an
equity security of the Company under Section 12 of the Exchange Act), or (ii)
the expiration of the term of the Option as set forth in the Option Agreement.
If, at the date of termination, the Optionee is not entitled to exercise his or
her entire Option, the shares covered by the unexercisable portion of the Option
shall revert to and again become available for issuance under the Plan. If,
after termination, the Optionee does not exercise his or her Option within the
time specified in the Option Agreement, the Option shall terminate, and the
shares covered by such Option shall revert to and again become available for
issuance under the Plan.

                  An Optionee's Option Agreement may also provide that if the
exercise of the Option following the termination of the Optionee's Continuous
Status as an Employee, Director, or Consultant (other than upon the Optionee's
death or disability) would result in liability under Section 16(b) of the
Exchange Act, then the Option shall terminate on the earlier of (i) the
expiration of the term of the Option set forth in the Option Agreement, or (ii)
the tenth (10th) day after the last date on which such exercise would result in
such liability under Section 16(b) of the Exchange Act.

         (g) DISABILITY OF OPTIONEE. In the event an Optionee's Continuous
Status as an Employee, Director or Consultant terminates as a result of the
Optionee's disability, the Optionee may exercise his or her Option (to the
extent that the Optionee was entitled to exercise it at the date of
termination), but only within such period of time ending on the earlier of (i)
the date twelve (12) months following such termination (or such longer or
shorter period specified in the Option Agreement, which period shall be no less
than six (6) months for Options granted prior to the date of the first
registration of an equity security of the Company under Section 12 of the
Exchange Act), or (ii) the expiration of the term of the Option as set forth in
the Option Agreement. If, at the date of termination, the Optionee is not
entitled to exercise his or her entire Option, the shares covered by the
unexercisable portion of the Option shall revert to and again become available
for issuance under the Plan. If, after termination, the Optionee does not
exercise his or her Option within the time specified herein, the Option shall
terminate, and the shares covered by such Option shall revert to and again
become available for issuance under the Plan.

         (h) DEATH OF OPTIONEE. In the event of the death of an Optionee during,
or within a period specified in the Option after the termination of, the
Optionee's Continuous Status as an Employee, Director or Consultant, the Option
may be exercised (to the extent the Optionee was entitled to exercise the Option
at the date of death) by the Optionee's estate, by a person who acquired the
right to exercise the Option by bequest or inheritance or by a person designated
to exercise the option upon the Optionee's death pursuant to subsection 6(d),
but only within the period ending on the earlier of (i) the date eighteen (18)
months following the date of death (or such longer or shorter period specified
in the Option Agreement, which period shall be no less than six (6) months for
Options granted prior to the date of the first registration of an equity


                                       8.
<PAGE>   9
security of the Company under Section 12 of the Exchange Act), or (ii) the
expiration of the term of such Option as set forth in the Option Agreement. If,
at the time of death, the Optionee was not entitled to exercise his or her
entire Option, the shares covered by the unexercisable portion of the Option
shall revert to and again become available for issuance under the Plan. If,
after death, the Option is not exercised within the time specified herein, the
Option shall terminate, and the shares covered by such Option shall revert to
and again become available for issuance under the Plan.

         (i) EARLY EXERCISE. The Option may, but need not, include a provision
whereby the Optionee may elect at any time while an Employee, Director or
Consultant to exercise the Option as to any part or all of the shares subject to
the Option prior to the full vesting of the Option. Any unvested shares so
purchased may be subject to a repurchase right in favor of the Company or to any
other restriction the Board determines to be appropriate.

                  With respect to Options granted prior to the date of the first
registration of an equity security of the Company under Section 12 of the
Exchange Act, the right of the Company under this subsection 6(i) to repurchase
at the original purchase price shall lapse at a minimum rate of twenty percent
(20%) per year over five (5) years from the date the Option was granted, and
(ii) such right shall be exercisable only within the ninety (90) day period
following the termination of employment or the relationship as a Director or
Consultant, and (iii) such right shall be exercisable only for cash or
cancellation of purchase money indebtedness for the shares. Should such right of
repurchase be assigned by the Company, the assignee shall pay the Company cash
equal to the difference between the original purchase price and the stock's Fair
Market Value if the original purchase price is less than the stock's Fair Market
Value.

         (j) RE-LOAD OPTIONS. Without in any way limiting the authority of the
Board or Committee to make or not to make grants of Options hereunder, the Board
or Committee shall have the authority (but not an obligation) to include as part
of any Option Agreement a provision entitling the Optionee to a further Option
(a "Re-Load Option") in the event the Optionee exercises the Option evidenced by
the Option agreement, in whole or in part, by surrendering other shares of
Common Stock in accordance with this Plan and the terms and conditions of the
Option Agreement. Any such Re-Load Option (i) shall be for a number of shares
equal to the number of shares surrendered as part or all of the exercise price
of such Option; (ii) shall have an expiration date which is the same as the
expiration date of the Option the exercise of which gave rise to such Re-Load
Option; and (iii) shall have an exercise price which is equal to one hundred
percent (100%) of the Fair Market Value of the Common Stock subject to the
Re-Load Option on the date of exercise of the original Option. Notwithstanding
the foregoing, a Re-Load Option which is an Incentive Stock Option (or a
Nonstatutory Stock Option granted prior to the date of the first registration of
an equity security of the Company under Section 12 of the Exchange Act) and
which is granted to a 10% stockholder (as described in subsection 5(c)), shall
have an exercise price which is equal to one hundred ten percent (110%) of the
Fair Market Value of the stock subject to the Re-Load Option on the date of
exercise of the original Option and shall have a term which is no longer than
five (5) years.


                                       9.

         Any such Re-Load Option may be an Incentive Stock Option or a
Nonstatutory Stock Option, as the Board or Committee may designate at the time
of the grant of the original Option; provided, however, that the designation of
any Re-Load Option as an Incentive Stock Option shall be subject to the one
hundred thousand dollar ($100,000) annual limitation on exercisability of
Incentive Stock Options described in subsection 11(d) of the Plan and in Section
422(d) of the Code. There shall be no Re-Load Options on a Re-Load Option. Any
such Re-Load Option shall be subject to the availability of sufficient shares
under subsection 4(a) and shall be subject to such other terms and conditions as
the Board or Committee may determine.

7.       TERMS OF STOCK BONUSES AND PURCHASES OF RESTRICTED STOCK.

         Each stock bonus or restricted stock purchase agreement shall be in
such form and shall contain such terms and conditions as the Board or the
Committee shall deem appropriate. The terms and conditions of stock bonus or
restricted stock purchase agreements may change from time to time, and the terms
and conditions of separate agreements need not be identical, but each stock
bonus or restricted stock purchase agreement shall include (through
incorporation of provisions hereof by reference in the agreement or otherwise)
the substance of each of the following provisions as appropriate:

         (a) PURCHASE PRICE. The purchase price under each restricted stock
purchase agreement shall be such amount as the Board or Committee shall
determine and designate in such agreement. Notwithstanding the foregoing
sentence, the purchase price applicable to each restricted stock purchase grant
made prior to the date of the first registration of an equity security of the
Company under Section 12 of the Exchange Act shall be not less than eighty-five
percent (85%) of the Fair Market Value of the stock subject to the purchase
right on the date such restricted stock purchase right is granted. In any event,
the Board or the Committee may determine that eligible participants in the Plan
may be awarded stock pursuant to a stock bonus agreement in consideration for
past services actually rendered to the Company or for its benefit.

         (b) TRANSFERABILITY. No rights under a stock bonus or restricted stock
purchase agreement shall be transferable except by will or the laws of descent
and distribution or, after the date of the first registration of an equity
security of the Company under Section 12 of the Exchange Act, if the agreement
so provides, pursuant to a DRO (as defined in subsection 6(d) hereof), so long
as stock awarded under such agreement remains subject to the terms of the
agreement.

         (c) CONSIDERATION. The purchase price of stock acquired pursuant to a
stock purchase agreement shall be paid either: (i) in cash at the time of
purchase; (ii) at the discretion of the Board or the Committee, according to a
deferred payment or other arrangement with the person to whom the stock is sold;
or (iii) in any other form of legal consideration that may be acceptable to the
Board or the Committee in their discretion. Notwithstanding the foregoing, the
Board or the Committee to which administration of the Plan has been delegated
may award stock pursuant to a stock bonus agreement in consideration for past
services actually rendered to the Company or for its benefit.


                                       10.
<PAGE>   11
         (d) VESTING. Shares of stock sold or awarded under the Plan may, but
need not, be subject to a repurchase option in favor of the Company in
accordance with a vesting schedule to be determined by the Board or the
Committee; provided, however, with respect to Stock Awards granted under this
Section 7 prior to the date of the first registration of an equity security of
the Company under Section 12 of the Exchange Act, that (i) the right of the
Company to repurchase at the original purchase price shall lapse at a minimum
rate of twenty percent (20%) per year over five (5) years from the date the
Stock Award was granted, and (ii) such right shall be exercisable only within
the ninety (90) day period following the termination of employment or the
relationship as a Director or Consultant, (iii) such right shall be exercisable
only for cash or cancellation of purchase money indebtedness for the shares, and
(iv) should such right of repurchase be assigned by the Company, the assignee
shall pay the Company cash equal to the difference between the original purchase
price and the stock's Fair Market Value if the original purchase price is less
than the stock's Fair Market Value.

         (e) TERMINATION OF EMPLOYMENT OR RELATIONSHIP AS A DIRECTOR OR
CONSULTANT. In the event a Participant's Continuous Status as an Employee,
Director or Consultant terminates, the Company may repurchase or otherwise
reacquire, subject to the limitations described in subsection 7(d), any or all
of the shares of stock held by that person which have not vested as of the date
of termination under the terms of the stock bonus or restricted stock purchase
agreement between the Company and such person.

8.       CANCELLATION AND RE-GRANT OF OPTIONS.

         (a) The Board or the Committee shall have the authority to effect, at
any time and from time to time, (i) the repricing of any outstanding Options
under the Plan and/or (ii) with the consent of any adversely affected holders of
Options, the cancellation of any outstanding Options under the Plan and the
grant in substitution therefor of new Options under the Plan covering the same
or different numbers of shares of stock, but having an exercise price per share
not less than eighty-five percent (85%) of the Fair Market Value (one hundred
percent (100%) of the Fair Market Value in the case of an Incentive Stock Option
or, in the case of an Option held by a 10% stockholder (as described in
subsection 5(b)), not less than one hundred ten percent (110%) of the Fair
Market Value) per share of stock on the new grant date.

         (b) Shares subject to an Option canceled under this Section 8 shall
continue to be counted against the maximum award of Options permitted to be
granted pursuant to subsection 5(c) of the Plan. The repricing of an Option
under this Section 8, resulting in a reduction of the exercise price, shall be
deemed to be a cancellation of the original Option and the grant of a substitute
Option; in the event of such repricing, both the original and the substituted
Options shall be counted against the maximum awards of Options permitted to be
granted pursuant to subsection 5(c) of the Plan. The provisions of this
subsection 8(b) shall be applicable only to the extent required by Section
162(m) of the Code.


                                       11.
<PAGE>   12
9.       COVENANTS OF THE COMPANY.

         (a) During the terms of the Stock Awards, the Company shall keep
available at all times the number of shares of stock required to satisfy such
Stock Awards.

         (b) The Company shall seek to obtain from each regulatory commission or
agency having jurisdiction over the Plan such authority as may be required to
issue and sell shares of stock upon exercise of the Stock Award; provided,
however, that this undertaking shall not require the Company to register under
the Securities Act of 1933, as amended (the "Securities Act"), either the Plan,
any Stock Award or any stock issued or issuable pursuant to any such Stock
Award. If, after reasonable efforts, the Company is unable to obtain from any
such regulatory commission or agency the authority which counsel for the Company
deems necessary for the lawful issuance and sale of stock under the Plan, the
Company shall be relieved from any liability for failure to issue and sell stock
upon exercise of such Stock Awards unless and until such authority is obtained.

10.      USE OF PROCEEDS FROM STOCK.

         Proceeds from the sale of stock pursuant to Stock Awards shall
constitute general funds of the Company.

11.      MISCELLANEOUS.

         (a) The Board shall have the power to accelerate the time at which a
Stock Award may first be exercised or the time during which a Stock Award or any
part thereof will vest pursuant to, notwithstanding the provisions in the Stock
Award stating the time at which it may first be exercised or the time during
which it will vest.

         (b) Neither an Employee, Director or Consultant, nor any person to whom
a Stock Award is transferred in accordance with the Plan, 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 such Stock Award unless and until such person has satisfied
all requirements for exercise of the Stock Award pursuant to its terms.

         (c) The Company shall deliver at least annually to the holder of any
Stock Award a balance sheet and an income statement. This section shall not
apply when issuance is limited to key employees whose duties in connection with
the Company assure them access to equivalent information.

         (d) Nothing in the Plan, or any instrument executed or Stock Award
granted pursuant thereto, shall confer upon any Employee, Director or Consultant
or other holder of Stock Awards any right to continue in the employ of the
Company or any Affiliate (or to continue acting as a Director of or Consultant)
or shall affect the right of the Company or any Affiliate to terminate the
employment of any Employee with or without cause, the right of the Company's
Board and or the Company's stockholders to remove any Director pursuant to the
terms of the


                                       12.
<PAGE>   13
Company's By-Laws and the provisions of any applicable law, or the right to
terminate the relationship of any Consultant pursuant to the terms of such
Consultant's agreement with the Company or Affiliate.

         (e) To the extent that the aggregate Fair Market Value (determined at
the time of grant) of stock with respect to which Incentive Stock Options
granted after 1986 are exercisable for the first time by any Optionee during any
calendar year under all plans of the Company and its Affiliates exceeds one
hundred thousand dollars ($100,000), the Options or portions thereof which
exceed such limit (according to the order in which they were granted) shall be
treated as Nonstatutory Stock Options.

         (f) The Company may require any person to whom a Stock Award is
granted, or any person to whom a Stock Award is transferred in accordance with
the Plan, as a condition of exercising or acquiring stock under any Stock Award,
(1) to give written assurances satisfactory to the Company as to such person's
knowledge and experience in financial and business matters and/or to employ a
purchaser representative reasonably satisfactory to the Company who is
knowledgeable and experienced in financial and business matters, and that he or
she is capable of evaluating, alone or together with the purchaser
representative, the merits and risks of exercising the Stock Award; and (2) to
give written assurances satisfactory to the Company stating that such person is
acquiring the stock subject to the Stock Award for such person's own account and
not with any present intention of selling or otherwise distributing the stock.
The foregoing requirements, and any assurances given pursuant to such
requirements, shall be inoperative if (i) the issuance of the shares upon the
exercise or acquisition of stock under the Stock Award has been registered under
a then currently effective registration statement under the Securities Act, or
(ii) as to any particular requirement, a determination is made by counsel for
the Company that such requirement need not be met in the circumstances under the
then applicable securities laws. The Company may, upon advice of counsel to the
Company, place legends on stock certificates issued under the Plan as such
counsel deems necessary or appropriate in order to comply with applicable
securities laws, including, but not limited to, legends restricting the transfer
of the stock.

         (g) To the extent provided by the terms of a Stock Award Agreement, the
person to whom a Stock Award is granted may satisfy any federal, state or local
tax withholding obligation relating to the exercise or acquisition of stock
under a Stock Award by any of the following means or by a combination of such
means: (1) tendering a cash payment; (2) authorizing the Company to withhold
shares from the shares of the common stock otherwise issuable to the participant
as a result of the exercise or acquisition of stock under the Stock Award; or
(3) delivering to the Company owned and unencumbered shares of the common stock
of the Company.

12.      ADJUSTMENTS UPON CHANGES IN STOCK.

         (a) If any change is made in the stock subject to the Plan, or subject
to any Stock Award, without the receipt of consideration by the Company (through
merger, consolidation, reorganization, recapitalization, reincorporation, stock
dividend, dividend in property other than


                                       13.
<PAGE>   14
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), the Plan will be appropriately
adjusted in the class(es) and maximum number of shares subject to the Plan
pursuant to subsection 4(a) and the maximum number of shares subject to award to
any person during any calendar year pursuant to subsection 5(c), and the
outstanding Stock Awards will be appropriately adjusted in the class(es) and
number of shares and price per share of stock subject to such outstanding Stock
Awards. Such adjustments shall be made by the Board or the Committee, 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: (1) a dissolution, liquidation or sale of
substantially all of the assets of the Company; (2) a merger or consolidation in
which the Company is not the surviving corporation; or (3) 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 (4) the acquisition by any person, entity or group within
the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act, or any
comparable successor provisions (excluding any employee benefit plan, or related
trust, sponsored or maintained by the Company or any Affiliate of the Company)
of the beneficial ownership (within the meaning of Rule 13d-3 promulgated under
the Exchange Act, or comparable successor rule) of securities of the Company
representing at least fifty percent (50%) of the combined voting power entitled
to vote in the election of directors, then (i) any surviving or acquiring
corporation shall assume Stock Awards outstanding under the Plan or shall
substitute similar Stock Awards (including a Stock Award to acquire the same
consideration paid to stockholders in the transaction described in this
subsection 12(b)) for those outstanding under the Plan or (ii) to the extent
permitted by applicable law, in the event any surviving or acquiring corporation
refuses to assume such Stock Awards or to substitute similar Stock Awards for
those outstanding under the Plan, (A) with respect to Stock Awards held by
persons then performing services as Employees, Directors or Consultants, the
vesting and, if applicable, exercisability of such Stock Awards shall be
accelerated prior to such event and any Stock Awards requiring exercise shall be
terminated if not exercised after such acceleration and at or prior to such
event, and (B) with respect to any other Stock Awards outstanding under the
Plan, such Stock Awards shall be terminated if not exercised prior to such
event.

13.      AMENDMENT OF THE PLAN AND STOCK AWARDS.

         (a) The Board at any time, and from time to time, may amend the Plan.
However, except as provided in Section 12 relating to adjustments upon changes
in stock, no amendment shall be effective unless approved by the stockholders of
the Company within twelve (12) months before or after the adoption of the
amendment, where the amendment will:

                         (i)        Increase the number of shares reserved for 
Stock Awards under the Plan;


                                       14.
<PAGE>   15
                        (ii)        Modify the requirements as to eligibility 
for participation in the Plan (to the extent such modification requires
stockholder approval in order for the Plan to satisfy the requirements of
Section 422 of the Code); or

                       (iii)        Modify the Plan in any other way if such 
modification requires stockholder approval in order for the Plan to satisfy the
requirements of Section 422 of the Code or to comply with the requirements of
Rule 16b-3.

         (b) The Board may in its sole discretion submit any other amendment to
the Plan for stockholder approval, including, but not limited to, amendments to
the Plan intended to satisfy the requirements of Section 162(m) of the Code and
the regulations promulgated thereunder regarding the exclusion of
performance-based compensation from the limit on corporate deductibility of
compensation paid to certain executive officers.

         (c) It is expressly contemplated that the Board may amend the Plan in
any respect the Board deems necessary or advisable to provide eligible
Employees, Directors or Consultants with the maximum benefits provided or to be
provided under the provisions of the Code and the regulations promulgated
thereunder relating to Incentive Stock Options and/or to bring the Plan and/or
Incentive Stock Options granted under it into compliance therewith.

         (d) Rights and obligations under any Stock Award granted before
amendment of the Plan shall not be impaired by any amendment of the Plan unless
(i) the Company requests the consent of the person to whom the Stock Award was
granted and (ii) such person consents in writing.

         (e) The Board at any time, and from time to time, may amend the terms
of any one or more Stock Award; provided, however, that the rights and
obligations under any Stock Award shall not be impaired by any such amendment
unless (i) the Company requests the consent of the person to whom the Stock
Award was granted and (ii) such person consents in writing.

14.      TERMINATION OR SUSPENSION OF THE PLAN.

         (a) The Board may suspend or terminate the Plan at any time. Unless
sooner terminated, the Plan shall terminate on July 15, 2006, which shall be
within ten (10) years from the date the Plan is adopted by the Board or approved
by the stockholders of the Company, whichever is earlier. No Stock Awards may be
granted under the Plan while the Plan is suspended or after it is terminated.

         (b) Rights and obligations under any Stock Award granted while the Plan
is in effect shall not be impaired by suspension or termination of the Plan,
except with the consent of the person to whom the Stock Award was granted.

15.      EFFECTIVE DATE OF PLAN.

         The Plan shall become effective as determined by the Board, but no
Stock Awards granted under the Plan shall be exercised unless and until the Plan
has been approved by the stockholders of the Company, which approval shall be
within twelve (12) months before or after the date the Plan is adopted by the
Board, and, if required, an appropriate permit has been issued by the
Commissioner of Corporations of the State of California.

                             INCENTIVE STOCK OPTION

__________________, Optionee:

         ALANEX CORPORATION (the "Company"), pursuant to its 1996 Equity
Incentive Plan (the "Plan"), has granted to you, the optionee named above, an
option to purchase shares of the common stock of the Company ("Common Stock").
This option is intended to qualify 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 or 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"). The grant of this
option and the issuance of shares upon the exercise of this option are also
intended to be exempt from the securities qualification requirements of the
California Corporations Code pursuant to Section 25102(o) of that code. Defined
terms not explicitly defined in this agreement but defined in the Plan shall
have the same definitions as in the Plan.

         The details of your option are as follows:

         1.       TOTAL NUMBER OF SHARES SUBJECT TO THIS OPTION. The total
number of shares of Common Stock subject to this option is ____________________
(__________).

         2.       VESTING. Subject to the limitations contained herein,
__________ of the shares will vest (become exercisable) on ____________, 19__
and __________ of the shares will then vest each ____________ [DRAFTING NOTE:
INDICATE APPLICABLE TIME PERIOD (E.G., MONTH OR YEAR)] thereafter until either
(i) you cease to provide services to the Company for any reason, or (ii) this
option becomes fully vested. [DRAFTING NOTE: MUST INDICATE AT LEAST 20% VESTING
PER YEAR PRIOR TO IPO]

         3.       EXERCISE PRICE AND METHOD OF PAYMENT.

                  (a)      EXERCISE PRICE. The exercise price of this option is
___________________________ ($___________) per share, being not less than the
fair market value of the Common Stock on the date of grant of this option.

                  (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:

                                       1.
<PAGE>   2
                           (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;

                           (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; or

                           (iv)     Payment by a combination of the methods of
payment permitted by subparagraph 3(b)(i) through 3(b)(iii) above.

         4.       WHOLE SHARES. 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 2, which
amounts to fewer than one hundred (100) shares, in which case, 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.       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.

         6.       TERM. The term of this option commences on __________, 19__,
the date of grant, and expires on ________________________ (the "Expiration
Date," which date shall be no more than ten (10) years from the date this option
is granted), unless this option expires sooner as set forth below or in the
Plan. In no event may this option be exercised on or after the Expiration Date.
This option shall terminate prior to the Expiration Date as follows: three (3)
months after the termination of your Continuous Status as an Employee, Director
or Consultant with the Company or an Affiliate of the Company unless one of the
following circumstances exists:

                  (a)      Your termination of Continuous Status as an Employee,
Director or Consultant is due to your permanent and total disability (within the
meaning of Section 422(c)(6) of the Code). This option will then expire on the
earlier of the Expiration Date set forth above

                                       2.
<PAGE>   3
or twelve (12) months following such termination of Continuous Status as an
Employee, Director or Consultant.

                  (b)      Your termination of Continuous Status as an Employee,
Director or Consultant is due to your death. This option will then expire on the
earlier of the Expiration Date set forth above or twelve (12) months after your
death.

                  (c)      If during any part of such three (3) month period you
may not exercise your option solely because of the condition set forth in
paragraph 5 above, then your option will not expire until the earlier of the
Expiration Date set forth above or until this option shall have been exercisable
for an aggregate period of three (3) months after your termination of Continuous
Status as an Employee, Director or Consultant.

                  (d)      If your exercise of the option within three (3)
months after termination of your Continuous Status as an Employee, Director or
Consultant with the Company or with an Affiliate of the Company would result in
liability under section 16(b) of the Securities Exchange Act of 1934, then your
option will expire 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 the
termination of your Continuous Status as an Employee, Director or Consultant
with the Company or an Affiliate of the Company.

         However, this option may be exercised following termination of
Continuous Status as an Employee, Director or Consultant only as to that number
of shares as to which it was exercisable on the date of termination of
Continuous Status as an Employee, Director or Consultant under the provisions of
paragraph 2 of this option.

         In order to obtain the federal income tax advantages associated with an
"incentive stock option," the Code requires that at all times beginning on the
date of grant of the option and ending on the day three (3) months before the
date of the option's exercise, you must be an employee of the Company or an
Affiliate of the Company, except in the event of your death or permanent and
total disability. The Company has provided for continued vesting or extended
exercisability of your option under certain circumstances for your benefit, but
cannot guarantee that your option will necessarily be treated as an "incentive
stock option" if you provide services to the Company or an Affiliate of the
Company as a consultant or exercise your option more than three (3) months after
the date your employment with the Company and all Affiliates of the Company
terminates.

         7.       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 require pursuant
to subsection 12(f) of the Plan.

                                       3.
<PAGE>   4
                  (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 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;

                           (ii)     you will notify the Company in writing
within fifteen (15) days after the date of any disposition of any of the shares
of the Common Stock issued upon exercise of this option that occurs within two
(2) years after the date of this option grant or within one (1) year after such
shares of Common Stock are transferred upon exercise of this option; and

                           (iii)    the Company (or a representative of the
underwriters) may, in connection with the first underwritten registration of the

                            NONSTATUTORY STOCK OPTION

__________________________, Optionee:

         ALANEX CORPORATION (the "Company"), pursuant to its 1996 Equity
Incentive Plan (the "Plan"), has 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 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 or 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"). The grant of this
option and the issuance of shares upon the exercise of this option are also
intended to be exempt from the securities qualification requirements of the
California Corporations Code pursuant to Section 25102(o) of that code. Defined
terms not explicitly defined in this agreement but defined in the Plan shall
have the same definitions as in the Plan.

         The details of your option are as follows:

         1. TOTAL NUMBER OF SHARES SUBJECT TO THIS OPTION. The total number of
shares of Common Stock subject to this option is ____________ (____________).

         2. VESTING. Subject to the limitations contained herein, __________ of
the shares will vest (become exercisable) on ____________, 19__ and __________
of the shares will then vest each ____________ [DRAFTING NOTE: INDICATE
APPLICABLE TIME PERIOD (E.G., MONTH OR YEAR)] thereafter until either (i) you
cease to provide services to the Company for any reason, or (ii) this option
becomes fully vested. [DRAFTING NOTE: MUST INDICATE AT LEAST 20% VESTING PER
YEAR PRIOR TO IPO]

         3. EXERCISE PRICE AND METHOD OF PAYMENT.

            (a) EXERCISE PRICE. The exercise price of this option is ___________
($________) per share, being not less than 85% of the fair market value of the
Common Stock on the date of grant of this option.

            (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:

                                       1.
<PAGE>   2
                (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;

                (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; or

                (iv)  Payment by a combination of the methods of payment
permitted by subparagraph 3(b)(i) through 3(b)(iii) above.

         4. WHOLE SHARES. 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 2, which
amounts to fewer than one hundred (100) shares, in which case, 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. 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.

         6. TERM. The term of this option commences on _________, 19__, the date
of grant and expires on _____________________ (the "Expiration Date," which date
shall be no more than ten (10) years from the date this option is granted),
unless this option expires sooner as set forth below or in the Plan. In no event
may this option be exercised on or after the Expiration Date. This option shall
terminate prior to the Expiration Date as follows: three (3) months after the
termination of your Continuous Status as an Employee, Director or Consultant
with the Company or an Affiliate of the Company for any reason or for no reason
unless:

            (a) such termination of Continuous Status as an Employee, Director
or Consultant 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 expire on the
earlier of the Expiration Date set

                                       2.
<PAGE>   3
forth above or twelve (12) months following such termination of Continuous
Status as an Employee, Director or Consultant; or

            (b) such termination of Continuous Status as an Employee, Director
or Consultant is due to your death, in which event the option shall expire on
the earlier of the Expiration Date set forth above or twelve (12) months after
your death; or

            (c) during any part of such three (3) month period the option is not
exercisable solely because of the condition set forth in paragraph 5 above, in
which event the option shall not expire 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 the termination of Continuous Status as an Employee,
Director or Consultant; or

            (d) exercise of the option within three (3) months after termination
of your Continuous Status as an Employee, Director or Consultant with the
Company or with an Affiliate of the Company would result in liability under
section 16(b) of the Securities Exchange Act of 1934 (the "Exchange Act), in
which case the option will expire 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
the termination of your Continuous Status as an Employee, Director or Consultant
with the Company or an Affiliate of the Company.

         However, this option may be exercised following termination of
Continuous Status as an Employee, Director or Consultant only as to that number
of shares as to which it was exercisable on the date of termination of
Continuous Status as an Employee, Director or Consultant under the provisions of
paragraph 2 of this option.

         7. 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 require pursuant to subsection
12(f) of the Plan.

            (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. You
also agree that any exercise of this option has not been completed and that the
Company is under no obligation to issue any Common Stock to you until such an
arrangement

                                       3.
<PAGE>   4
is established or the Company's tax withholding obligations are satisfied, as
determined by the Company; 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.

         8.  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. Notwithstanding the foregoing, 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.

         9.  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 addition,
nothing in this option shall obligate the Company or any Affiliate of the
Company, or their respective stockholders, Board of Directors, officers, or
employees to continue any relationship which you might have as a Director or
Consultant for the Company or Affiliate of the Company.

         10. NOTICES. Any notices provided for in this option or the Plan 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.

         11. GOVERNING PLAN DOCUMENT. This option is subject to all the
provisions of the Plan, a copy of which is attached hereto and its provisions
are hereby made a part of this option, including without limitation the
provisions of Section 6 of the Plan relating to option provisions, and is
further subject to all interpretations, amendments, rules and regulations which

                               ALANEX CORPORATION

                          EMPLOYEE STOCK PURCHASE PLAN

                              ADOPTED JULY 17, 1996

1.       PURPOSE.

         (a)      The purpose of the Employee Stock Purchase Plan (the "Plan")
is to provide a means by which employees of Alanex Corporation, a California
corporation (the "Company"), and its Affiliates, as defined in subparagraph
1(b), which are designated as provided in subparagraph 2(b), may be given an
opportunity to purchase stock of the Company.

         (b)      The word "Affiliate" as used in the Plan means any parent
corporation or subsidiary corporation of the Company, as those terms are defined
in Sections 424(e) and (f), respectively, of the Internal Revenue Code of 1986,
as amended (the "Code").

         (c)      The Company, by means of the Plan, seeks to retain the
services of its employees, to secure and retain the services of new employees,
and to provide incentives for such persons to exert maximum efforts for the
success of the Company.

         (d)      The Company intends that the rights to purchase stock of the
Company granted under the Plan be considered options issued under an "employee
stock purchase plan" as that term is defined in Section 423(b) of the Code.

2.       ADMINISTRATION.

         (a)      The Plan shall be administered by the Board of Directors (the
"Board") of the Company unless and until the Board delegates administration to a
Committee, as provided in subparagraph 2(c). Whether or not the Board has
delegated administration, the Board shall have the final power to determine all
questions of policy and expediency that may arise in the administration of the
Plan.

         (b)      The Board shall have the power, subject to, and within the
limitations of, the express provisions of the Plan:

                  (i)      To determine when and how rights to purchase stock of
the Company shall be granted and the provisions of each offering of such rights
(which need not be identical).

                  (ii)     To designate from time to time which Affiliates of
the Company shall be eligible to participate in the Plan.

                  (iii)    To construe and interpret the Plan and rights granted
under it, and to establish, amend and revoke rules and regulations for its
administration. The Board, in the

                                       1.
<PAGE>   2
exercise of this power, may correct any defect, omission or inconsistency in the
Plan, in a manner and to the extent it shall deem necessary or expedient to make
the Plan fully effective.

                  (iv)     To amend the Plan as provided in paragraph 13.

                  (v)      Generally, to exercise such powers and to perform
such acts as the Board deems necessary or expedient to promote the best
interests of the Company and its Affiliates.

         (c)      The Board may delegate administration of the Plan to a
Committee composed of not fewer than two (2) members of the Board (the
"Committee"). If administration is delegated to a Committee, the Committee shall
have, in connection with the administration of the Plan, the powers theretofore
possessed by the Board, subject, however, to such resolutions, not inconsistent
with the provisions of the Plan, as may be adopted from time to time by the
Board. The Board may abolish the Committee at any time and revest in the Board
the administration of the Plan.

3.       SHARES SUBJECT TO THE PLAN.

         (a)      Subject to the provisions of paragraph 12 relating to
adjustments upon changes in stock, the stock that may be sold pursuant to rights
granted under the Plan shall not exceed in the aggregate one hundred twenty-five
thousand (125,000) shares of the Company's common stock (the "Common Stock").
If any right granted under the Plan shall for any reason terminate without
having been exercised, the Common Stock not purchased under such right shall
again become available for the Plan.

         (b)      The stock subject to the Plan may be unissued shares or
reacquired shares, bought on the market or otherwise.

4.       GRANT OF RIGHTS; OFFERING.

         (a)      The Board or the Committee may from time to time grant or
provide for the grant of rights to purchase Common Stock of the Company under
the Plan to eligible employees (an "Offering") on a date or dates (the "Offering
Date(s)") selected by the Board or the Committee. Each Offering shall be in such
form and shall contain such terms and conditions as the Board or the Committee
shall deem appropriate. The provisions of separate Offerings need not be
identical, but each Offering shall include (through incorporation of the
provisions of this Plan by reference in the Offering or otherwise) the period
during which the Offering shall be effective, which period shall not exceed
twenty-seven (27) months beginning with the Offering Date, and the substance of
the provisions contained in paragraphs 5 through 8, inclusive.

         (b)      If an employee has more than one right outstanding under the
Plan, unless he or she otherwise indicates in agreements or notices delivered
hereunder: (1) each agreement or notice delivered by that employee will be
deemed to apply to all of his or her rights under the Plan, and (2) a right with
a lower exercise price (or an earlier-granted right, if two rights have

                                       2.
<PAGE>   3
identical exercise prices), will be exercised to the fullest possible extent
before a right with a higher exercise price (or a later-granted right, if two
rights have identical exercise prices) will be exercised.

5.       ELIGIBILITY.

         (a)      Rights may be granted only to employees of the Company or, as
the Board or the Committee may designate as provided in subparagraph 2(b), to
employees of any Affiliate of the Company. Except as provided in subparagraph
5(b), an employee of the Company or any Affiliate shall not be eligible to be
granted rights under the Plan, unless, on the Offering Date, such employee has
been in the employ of the Company or any Affiliate for such continuous period
preceding such grant as the Board or the Committee may require, but in no event
shall the required period of continuous employment be greater than two (2)
years. In addition, unless otherwise determined by the Board or the Committee
and set forth in the terms of the applicable Offering, no employee of the
Company or any Affiliate shall be eligible to be granted rights under the Plan,
unless, on the Offering Date, such employee's customary employment with the
Company or such Affiliate is for at least twenty (20) hours per week and at
least five (5) months per calendar year.

         (b)      The Board or the Committee may provide that, each person who,
during the course of an Offering, first becomes an eligible employee of the
Company or designated Affiliate will, on a date or dates specified in the
Offering which coincides with the day on which such person becomes an eligible
employee or occurs thereafter, receive a right under that Offering, which right
shall thereafter be deemed to be a part of that Offering. Such right shall have
the same characteristics as any rights originally granted under that Offering,
as described herein, except that:

                  (i)      the date on which such right is granted shall be the
"Offering Date" of such right for all purposes, including determination of the
exercise price of such right;

                  (ii)     the period of the Offering with respect to such right
shall begin on its Offering Date and end coincident with the end of such
Offering; and

                  (iii)    the Board or the Committee may provide that if such
person first becomes an eligible employee within a specified period of time
before the end of the Offering, he or she will not receive any right under that
Offering.

         (c)      No employee shall be eligible for the grant of any rights
under the Plan if, immediately after any such rights are granted, such employee
owns stock possessing five percent (5%) or more of the total combined voting
power or value of all classes of stock of the Company or of any Affiliate. For
purposes of this subparagraph 5(c), the rules of Section 424(d) of the Code
shall apply in determining the stock ownership of any employee, and stock which
such employee may purchase under all outstanding rights and options shall be
treated as stock owned by such employee.

                                       3.
<PAGE>   4
         (d)      An eligible employee may be granted rights under the Plan only
if such rights, together with any other rights granted under "employee stock
purchase plans" of the Company and any Affiliates, as specified by Section
423(b)(8) of the Code, do not permit such employee's rights to purchase stock of
the Company or any Affiliate to accrue at a rate which exceeds twenty-five
thousand dollars ($25,000) of fair market value of such stock (determined at the
time such rights are granted) for each calendar year in which such rights are
outstanding at any time.

         (e)      Officers of the Company and any designated Affiliate shall be
eligible to participate in Offerings under the Plan, provided, however, that the
Board may provide in an Offering that certain employees who are highly
compensated employees within the meaning of Section 423(b)(4)(D) of the Code
shall not be eligible to participate.

6.       RIGHTS; PURCHASE PRICE.

         (a)      On each Offering Date, each eligible employee, pursuant to an
Offering made under the Plan, shall be granted the right to purchase up to the
number of shares of Common Stock of the Company purchasable with a percentage
designated by the Board or the Committee not exceeding fifteen percent (15%) of
such employee's Earnings (as defined in subparagraph 7(a)) during the period
which begins on the Offering Date (or such later date as the Board or the
Committee determines for a particular Offering) and ends on the date stated in
the Offering, which date shall be no later than the end of the Offering. The
Board or the Committee shall establish one or more dates during an Offering (the
"Purchase Date(s)") on which rights granted under the Plan shall be exercised
and purchases of Common Stock effected in accordance with such Offering.

         (b)      In connection with each Offering made under this Plan, the
Board or the Committee shall specify a maximum number of shares which may be
purchased by any employee as well as a maximum aggregate number of shares which
may be purchased by all eligible employees pursuant to such Offering. In
addition, in connection with each Offering which contains more than one Purchase
Date, the Board or the Committee may specify a maximum aggregate number of
shares which may be purchased by all eligible employees on any given Purchase
Date under the Offering. If the aggregate purchase of shares upon exercise of
rights granted under the Offering would exceed any such maximum aggregate
number, the Board or the Committee shall make a pro rata allocation of the
shares available in as nearly a uniform manner as shall be practicable and as it
shall deem to be equitable.

         (c)      The purchase price of stock acquired pursuant to rights
granted under the Plan shall be not less than the lesser of:

                  (i)      an amount equal to eighty-five percent (85%) of the
fair market value of the stock on the Offering Date; or

                  (ii)     an amount equal to eighty-five percent (85%) of the
fair market value of the stock on the Purchase Date.

                                       4.
<PAGE>   5
7.       PARTICIPATION; WITHDRAWAL; TERMINATION.

         (a)      An eligible employee may become a participant in the Plan
pursuant to an Offering by delivering a participation agreement to the Company
within the time specified in the Offering, in such form as the Company provides.
Each such agreement shall authorize payroll deductions of up to the maximum
percentage specified by the Board or the Committee of such employee's Earnings
during the Offering. "Earnings" is defined as an employee's regular salary or
wages (including amounts thereof elected to be deferred by the employee, that
would otherwise have been paid, under any cash or deferred arrangement
established by the Company), which shall include commissions and overtime pay,
but shall exclude bonuses, incentive pay, profit sharing, other remuneration
paid directly to the employee, the cost of employee benefits paid for by the
Company or an Affiliate, education or tuition reimbursements, imputed income
arising under any group insurance or benefit program, traveling expenses,
business and moving expense reimbursements, income received in connection with
stock options, contributions made by the Company or an Affiliate under any
employee benefit plan, and similar items of compensation. The payroll deductions
made for each participant shall be credited to an account for such participant
under the Plan and shall be deposited with the general funds of the Company or
an Affiliate. A participant may reduce (including to zero), increase or begin
such payroll deductions after the beginning of any Offering only as provided for
in the Offering. A participant may make additional payments into his or her
account only if specifically provided for in the Offering and only if the
participant has not had the maximum amount withheld during the Offering.

         (b)      At any time during an Offering, a participant may terminate
his or her payroll deductions under the Plan and withdraw from the Offering by
delivering to the Company a notice of withdrawal in such form as the Company
provides. Such withdrawal may be elected at any time prior to the end of the
Offering except as provided by the Board or the Committee in the Offering. Upon
such withdrawal from the Offering by a participant, the Company shall distribute
to such participant all of his or her accumulated payroll deductions (reduced to
the extent, if any, such deductions have been used to acquire stock for the
participant) under the Offering, without interest, and such participant's
interest in that Offering shall be automatically terminated. A participant's
withdrawal from an Offering will have no effect upon such participant's
eligibility to participate in any other Offerings under the Plan but such
participant will be required to deliver a new participation agreement in order
to participate in subsequent Offerings under the Plan.

         (c)      Rights granted pursuant to any Offering under the Plan shall
terminate immediately upon cessation of any participating employee's employment
with the Company and any designated Affiliate, for any reason, and the Company
shall distribute to such terminated employee all of his or her accumulated
payroll deductions (reduced to the extent, if any, such deductions have been
used to acquire stock for the terminated employee), under the Offering, without
interest.

                                       5.
<PAGE>   6
         (d)      Rights granted under the Plan shall not be transferable, and,
except as provided in paragraph 14, shall be exercisable only by the person to
whom such rights are granted.

8.       EXERCISE.

         (a)      On each date specified therefor in the relevant Offering
("Purchase Date"), each participant's accumulated payroll deductions and other
additional payments specifically provided for in the Offering (without any
increase for interest) will be applied to the purchase of whole shares of stock
of the Company, up to the maximum number of shares permitted pursuant to the
terms of the Plan and the applicable Offering, at the purchase price specified
in the Offering. No fractional shares shall be issued upon the exercise of
rights granted under the Plan. The amount, if any, of accumulated payroll
deductions remaining in each participant's account after the purchase of shares
which is less than the amount required to purchase one share of stock on the
final Purchase Date of an Offering shall be held in each such participant's
account for the purchase of shares under the next Offering under the Plan,
unless such participant withdraws from such next Offering, as provided in
subparagraph 7(b), or is no longer eligible to be granted rights under the Plan,
as provided in paragraph 5, in which case such amount shall be distributed to
the participant after such final Purchase Date, without interest. The amount, if
any, of accumulated payroll deductions remaining in any participant's account
after the purchase of shares which is equal to the amount required to purchase
whole shares of stock on the final Purchase Date of an Offering shall be
distributed in full to the participant after such Purchase Date, without
interest.

         (b)      No rights granted under the Plan may be exercised to any
extent unless the Plan (including rights granted thereunder) is covered by an
effective registration statement pursuant to the Securities Act of 1933, as
amended (the "Securities Act"). If on a Purchase Date in any Offering hereunder
the Plan is not so registered, no rights granted under the Plan or any Offering
shall be exercised on such Purchase Date, and the Purchase Date shall be delayed
until the Plan is subject to such an effective registration statement, except
that the Purchase Date shall not be delayed more than twelve (12) months and the
Purchase Date shall in no event be more than twenty-seven (27) months from the
Offering Date. If on the Purchase Date of any Offering hereunder, as delayed to
the maximum extent permissible, the Plan is not registered, no rights granted
under the Plan or any Offering shall be exercised and all payroll deductions
accumulated during the Offering (reduced to the extent, if any, such deductions
have been used to acquire stock) shall be distributed to the participants,
without interest.

9.       COVENANTS OF THE COMPANY.

         (a)      During the terms of the rights granted under the Plan, the
Company shall keep available at all times the number of shares of stock required
to satisfy such rights.

         (b)      The Company shall seek to obtain from each regulatory
commission or agency having jurisdiction over the Plan such authority as may be
required to issue and sell shares of stock upon exercise of the rights granted
under the Plan. If, after reasonable efforts, the

                                       6.
<PAGE>   7
Company is unable to obtain from any such regulatory commission or agency the
authority which counsel for the Company deems necessary for the lawful issuance
and sale of stock under the Plan, the Company shall be relieved from any
liability for failure to issue and sell stock upon exercise of such rights
unless and until such authority is obtained.

10.      USE OF PROCEEDS FROM STOCK.

         Proceeds from the sale of stock pursuant to rights granted under the
Plan shall constitute general funds of the Company.

11.      RIGHTS AS A STOCKHOLDER.

         A participant shall not be deemed to be the holder of, or to have any
of the rights of a holder with respect to, any shares subject to rights granted
under the Plan unless and until the participant's stockholdings acquired upon
exercise of rights under the Plan are recorded in the books of the Company.

12.      ADJUSTMENTS UPON CHANGES IN STOCK.

         (a)      If any change is made in the stock subject to the Plan, or
subject to any rights granted under the Plan (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 otherwise), the Plan and outstanding
rights will be appropriately adjusted in the class(es) and maximum number of
shares subject to the Plan and the class(es) and number of shares and price per
share of stock subject to outstanding rights.

         (b)      In the event of: (1) a dissolution or liquidation of the
Company; (2) a merger or consolidation in which the Company is not the surviving
corporation; (3) 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 (4) any other capital
reorganization in which more than fifty percent (50%) of the shares of the
Company entitled to vote are exchanged, then, as determined by the Board in its
sole discretion (i) any surviving corporation may assume outstanding rights or
substitute similar rights for those under the Plan, (ii) such rights may
continue in full force and effect, or (iii) participants' accumulated payroll
deductions may be used to purchase Common Stock immediately prior to the
transaction described above and the participants' rights under the ongoing
Offering terminated.

13.      AMENDMENT OF THE PLAN.

         (a)      The Board at any time, and from time to time, may amend the
Plan. However, except as provided in paragraph 12 relating to adjustments upon
changes in stock, no amendment shall be effective unless approved by the
stockholders of the Company within twelve (12) months

                                       7.
<PAGE>   8
before or after the adoption of the amendment, where the amendment will:

                  (i)      Increase the number of shares reserved for rights
         under the Plan;

                  (ii)     Modify the provisions as to eligibility for
         participation in the Plan (to the extent such modification requires
         stockholder approval in order for the Plan to obtain employee stock
         purchase plan treatment under Section 423 of the Code or to comply with
         the requirements of Rule 16b-3 promulgated under the Securities
         Exchange Act of 1934, as amended ("Rule 16b-3")); or

                  (iii)    Modify the Plan in any other way if such modification
         requires stockholder approval in order for the Plan to obtain employee
         stock purchase plan treatment under Section 423 of the Code or to
         comply with the requirements of Rule 16b-3.

It is expressly contemplated that the Board may amend the Plan in any respect
the Board deems necessary or advisable to provide eligible employees with the
maximum benefits provided or to be provided under the provisions of the Code and
the regulations promulgated thereunder relating to employee stock purchase plans
and/or to bring the Plan and/or rights granted under it into compliance
therewith.

         (b)      Rights and obligations under any rights granted before
amendment of the Plan shall not be altered or impaired by any amendment of the
Plan, except with the consent of the person to whom such rights were granted or
except as necessary to comply with any laws or governmental regulation.

14.      DESIGNATION OF BENEFICIARY.

         (a)      A participant may file a written designation of a beneficiary
who is to receive any shares and cash, if any, from the participant's account
under the Plan in the event of such participant's death subsequent to the end of
an Offering but prior to delivery to him of such shares and cash. In addition, a
participant may file a written designation of a beneficiary who is to receive
any cash from the participant's account under the Plan in the event of such
participant's death during an Offering.

         (b)      Such designation of beneficiary may be changed by the
participant at any time by written notice. In the event of the death of a
participant and in the absence of a beneficiary validly designated under the
Plan who is living at the time of such participant's death, the Company shall
deliver such shares and/or cash to the executor or administrator of the estate
of the participant, or if no such executor or administrator has been appointed
(to the knowledge of the Company), the Company, in its discretion, may deliver
such shares and/or cash to the spouse or to any one or more dependents or
relatives of the participant, or if no spouse, dependent or relative is known to
the Company, then to such other person as the Company may designate.

                                       8.
<PAGE>   9
15.      TERMINATION OR SUSPENSION OF THE PLAN.

         (a)      The Board may suspend or terminate the Plan at any time. No
rights may be granted under the Plan while the Plan is suspended or after it is
terminated.

         (b)      Rights and obligations under any rights granted while the Plan
is in effect shall not be altered or impaired by suspension or termination of
the Plan, except as expressly provided in the Plan or with the consent of the
person to whom such rights were granted or except as necessary to comply with
any laws or governmental regulation.

16.      EFFECTIVE DATE OF PLAN.

         The Plan shall become effective upon the effectiveness of the Company's
initial public offering of shares of common stock, but no rights granted under
the Plan shall be exercised unless and until the Plan has been approved by the
stockholders of the Company.

                               ALANEX CORPORATION

                     EMPLOYEE STOCK PURCHASE PLAN OFFERING




1.       GRANT; OFFERING DATE.

         (a)  The Board of Directors of Alanex Corporation (the "Company"),
pursuant to the Company's Employee Stock Purchase Plan (the "Plan"), hereby
authorizes the grant of rights to purchase shares of common stock of the Company
("Common Stock") to all Eligible Employees (an "Offering"). The first Offering
shall begin simultaneously with the initial public offering of the Company's
Common Stock, or the effective date of such initial public offering (the
"Effective Date") and end on August 31, 1998 (the "Initial Offering").
Thereafter, an Offering shall begin on September 1 every second year, beginning
with calendar year 1998, and shall end on the day prior to the second
anniversary of its Offering Date. The first day of an Offering is that
Offering's "Offering Date." If an Offering Date does not fall on a day during
which the Company's Common Stock is actively traded, then the Offering Date
shall be the next subsequent day during which the Company's Common Stock is
actively traded.

         (b)  Prior to the commencement of any Offering, the Board of Directors
(or the Committee described in subparagraph 2(c) of the Plan, if any) may change
any or all terms of such Offering and any subsequent Offerings. The granting of
rights pursuant to each Offering hereunder shall occur on each respective
Offering Date unless, prior to such date (a) the Board of Directors (or such
Committee) determines that such Offering shall not occur, or (b) no shares
remain available for issuance under the Plan in connection with the Offering.

2.       ELIGIBLE EMPLOYEES.

         (a)  All employees of the Company and each of its Affiliates (as
defined in the Plan) incorporated in the United States shall be granted rights
to purchase Common Stock under each Offering on the Offering Date of such
Offering, (an "Eligible Employee"). Notwithstanding the foregoing, no employee
who (i) receives compensation from the Company and its Affiliates in excess of
ninety thousand dollars ($90,000) on an annualized basis (provided that such
employee is a "highly compensated employee" within the meaning of Section
423(b)(4)(D) of the Code), or (ii) is disqualified by subparagraph 5(c) or 5(d)
of the Plan shall be an Eligible Employee or be granted rights under an
Offering. An employee need not otherwise satisfy the employment requirements of
subparagraph 5(a) (that is, an employee need not be customarily employed for at
least twenty (20) hours per week and at least five (5) months per calendar year)
to be an Eligible Employee granted rights under the Offering.

         (b)  Notwithstanding the foregoing, each person who first becomes an
Eligible Employee during any Offering will, on the day after the first Purchase
Date (that is, on September 1 or March 1) coincident with or next following the
date such person first satisfies


                                       1.

<PAGE>   11
any service requirement to become an Eligible Employee, receive a right under
such Offering, which right shall thereafter be deemed to be a part of the
Offering. Such right shall have the same characteristics as any rights
originally granted under the Offering except that:

                  (1)      the date on which such right is granted shall be the
"Offering Date" of such right for all purposes, including determination of the
exercise price of such right; and

                  (2)      the Offering for such right shall begin on its
Offering Date and end coincident with the end of the ongoing Offering.

3.       RIGHTS.

         (a)  Subject to the limitations contained herein and in the Plan, on
each Offering Date each Eligible Employee shall be granted the right to purchase
the number of shares of Common Stock purchasable with up to fifteen percent
(15%) of such employee's Earnings paid during the period of such Offering
beginning after such Eligible Employee first commences participation; provided,
however, that no employee may purchase Common Stock in a particular year with
more than fifteen percent (15%) of such employee's Earnings in such year under
all ongoing Offerings under the Plan and all other Company plans intended to
qualify as "employee stock purchase plans" under Section 423 of the Internal
Revenue Code of 1986, as amended (the "Code"). "Earnings" for this purpose means
an employee's regular salary or wages (including amounts the employee elected to
defer, but which would otherwise have been paid under a 401(k) plan or similar
arrangement), commissions, overtime pay, bonuses and incentive pay. The maximum
number of shares of Common Stock an Eligible Employee may purchase on any
Purchase Date in an Offering shall be such number of shares as has a fair market
value (determined as of the Offering Date for such Offering) equal to (x)
$25,000 multiplied by the number of calendar years in which the right under such
Offering has been outstanding at any time, minus (y) the fair market value of
any other shares of Common Stock (determined as of the relevant Offering Date
with respect to such shares) which, for purposes of the limitation of Section
423(b)(8) of the Code, are attributed to any of such calendar years in which the
right is outstanding. The amount in clause (y) of the previous sentence shall be
determined in accordance with regulations applicable under Section 423(b)(8) of
the Code based on (i) the number of shares previously purchased with respect to
such calendar years pursuant to such Offering or any other Offering under the
Plan, or pursuant to any other Company plans intended to qualify as "employee
stock purchase plans" under Section 423 of the Code, and (ii) the number of
shares subject to other rights outstanding on the Offering Date for such
Offering pursuant to the Plan or any other such Company plan.

         (b)  The maximum aggregate number of shares available to be purchased
by all Eligible Employees under an Offering on any Purchase Date shall be the
number of shares remaining available under the Plan on the applicable Purchase
Date. If the aggregate purchase of shares of Common Stock upon exercise of
rights granted under the Offering would exceed the maximum aggregate number of
shares available, the Board shall make a pro rata allocation of the shares
available in a uniform and equitable manner.



                                       2.

<PAGE>   12
4.       PURCHASE PRICE.

         The purchase price of the Common Stock under the Offering shall be the
lesser of eighty-five percent (85%) of the fair market value of the Common Stock
on the Offering Date or eighty-five percent (85%) of the fair market value of
the Common Stock on the Purchase Date, in each case rounded up to the nearest
whole cent per share. For the Initial Offering, the fair market value of the
Common Stock at the time when the Offering commences shall be the price per
share at which shares of Common Stock are first sold to the public in the
Company's initial public offering as specified in the final prospectus with
respect to that offering.

5.       PARTICIPATION.

         (a)  Except as otherwise provided in this paragraph 5, an Eligible
Employee may elect to participate in an Offering on his or her Offering Date. An
Eligible Employee shall become a participant in an Offering by delivering an
agreement authorizing payroll deductions. Such deductions may be in whole
percentages only, with a minimum percentage of one percent (1%), and a maximum
percentage of fifteen percent (15%). A participant may not make additional
payments into his or her account. The agreement shall be made on such enrollment
form as the Company provides, and must be delivered to the Company before the
applicable Offering Date to be effective for that Offering (or the remaining
portion of that Offering), unless a later time for filing the enrollment form is
set by the Board for all Eligible Employees with respect to a given Offering
Date. As to the Initial Offering, the time for filing an enrollment form and
commencing participation for individuals who are Eligible Employees on the
Offering Date for the Initial Offering shall be determined by the Company and
communicated to such Eligible Employees.

         (b)  A participant may not increase his or her participation level
during the course of an Offering. A participant may reduce (including to zero)
his or her participation level only once during any six month period ending on a
Purchase Date by delivering a notice to the Company in such form and at such
time as the Company provides. Notwithstanding the foregoing, a participant may
make a second reduction during such six month period if such second reduction is
to zero. A participant may withdraw from an Offering and receive his or her
accumulated payroll deductions from the Offering (reduced to the extent, if any,
such deductions have been used to acquire Common Stock for the participant on
any prior Purchase Dates), without interest, at any time prior to the end of the
Offering, except the 10 days immediately preceding any Purchase Date, by
delivering a withdrawal notice to the Company in such form as the Company
provides.

6.       PURCHASES.

         Subject to the limitations contained herein, on each Purchase Date,
each participant's accumulated payroll deductions (without any increase for
interest) shall be applied to the purchase of whole shares of Common Stock, up
to the maximum number of shares permitted under the Plan and the Offering.
"Purchase Date" shall be defined as each February 28 and August 31 (i.e., the
first Purchase Date of the Initial Offering shall be February 28, 1997 and


                                       3.

<PAGE>   13
the next Purchase Date shall be August 31, 1997). If a Purchase Date does not
fall on a day during which the Company's Common Stock is actively traded then
the Purchase Date shall be the nearest prior day during which the Company's
Common Stock is actively traded.


7.       TERMINATION.

         Rights granted under the Offering shall terminate immediately upon
cessation of any participating employee's employment with the Company and any
designated Affiliate, for any reason, and the Company shall distribute to such
terminated employee all of his or her accumulated payroll deductions (reduced to
the extent, if any, such deductions have been used to acquire stock for the
terminated employee), under the Offering, without interest.

8.       NOTICES AND AGREEMENTS.

         Any notices or agreements provided for in an Offering or the Plan shall
be given in writing, in a form provided by the Company, and unless specifically
provided for in the Plan or this Offering shall be deemed effectively given upon
receipt or, in the case of notices and agreements delivered by the Company, five
(5) days after deposit in the United States mail, postage prepaid.

9.       EXERCISE CONTINGENT ON SHAREHOLDER APPROVAL.

         The rights granted under an Offering are subject to the approval of the
Plan by the stockholders as required for the Plan to obtain treatment as a
tax-qualified employee stock purchase plan under Section 423 of the Code and to
comply with the requirements of the exemption from potential liability under
Section 16(b) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), set forth in Rule 16b-3 promulgated under the Exchange Act.

10.      OFFERING SUBJECT TO PLAN.

         Each Offering is subject to all the provisions of the Plan, and its
provisions are hereby made a part of the Offering, and is further subject to all
interpretations, amendments, rules and regulations which may from time to time
be promulgated and adopted pursuant to the Plan. In the event of any conflict
between the provisions of an Offering and those of the Plan (including
interpretations, amendments, rules and regulations which may from time to time
be promulgated and adopted pursuant to the Plan), the provisions of the Plan
shall control.

                                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.

day and year first above written.

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

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
    the part of the Company, and upon issuance and delivery against payment
    therefor in accordance with the terms of the New Warrant, the Warrant Shares
    will be duly and validly issued, outstanding, fully paid and nonassessable.
    To the best of our knowledge, there are no options, warrants, conversion
    privileges, preemptive rights or other rights presently

certificate or certificated for the Exercise Shares so purchased, registered in

                THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
                ACT OF 1933.  THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR
                HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
                STATEMENT AS TO THE SECURITIES UNDER SAID ACT OR AN OPINION OF
                COUNSEL SATISFACTORY TO THE CORPORATION THAT SUCH REGISTRATION
                IS NOT REQUIRED.

                THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A 
                RIGHT OF FIRST REFUSAL OPTION IN FAVOR OF THE CORPORATION

                CORPORATION.

                                       4.
<PAGE>   5
                (c)  The Holder further agrees that the Corporation (or a
representative of the underwriters of the Corporation) may, in connection with
the first underwritten registration of the offering of any securities of the
Corporation under the Act, require that Holder not sell or otherwise transfer or
dispose of all or any part of this Warrant or any Exercise Shares during such
period (not to exceed one hundred eighty (180) days) following the effective
date (the "Effective Date") of the registration statement of the Corporation
filed under the Act as may be requested by the Corporation or the representative
of the underwriters; provided that all officers and  directors and each holder
of five percent (5%) or more of the Corporation's outstanding voting securities
shall have agreed to market stand-off restrictions no less restrictive than
those set forth in this Section 4(c).  Holder further agrees that the
Corporation may impose stop-transfer instructions with respect to securities
subject to the foregoing restrictions until the end of such period.

                SECTION 5.  Adjustment of Exercise Price and Number of Exercise
Shares Issuable. The Exercise Price and the number of Exercise Shares issuable
upon the exercise of the Warrant are subject to adjustment from time to time
upon the occurrence of the events enumerated in this Section 5.  For purposes of
the Section 5, "Common Stock" means shares now or hereafter authorized of any
class of common stock of the Corporation and any other stock of the Corporation,
however, designated, that has the right (subject to any prior rights of any
class of series of preferred stock) to participate in any distribution of the
assets or earnings of the Corporation without limit as to per share amount.

                (a)  Adjustment for Change in Capital Stock.

                     If the Corporation:

                     (1)  pays a dividend or makes a distribution on its Common
                Stock in shares of its Common Stock;

                     (2)  subdivides its outstanding shares of Common Stock into
                a greater number of shares.

                     (3)  combines its outstanding shares of Common Stock into a
                smaller number of shares;

                     (4)  makes a distribution on its Common Stock in shares of
                its capital stock other than Common Stock or preferred stock; or

                     (5)  issues by reclassification of its Common Stock any
                shares of its capital stock;

then the Exercise Price in effect immediately prior to such action shall be
proportionately adjusted so that the holder of any Warrant thereafter exercised
may receive the aggregate number and kind of shares of capital stock of the
Corporation which he would have owned immediately following such action if such
Warrant had been exercised immediately prior to such action.


                                       5.
<PAGE>   6
                The adjustment shall become effective immediately after the
record date in the case of a dividend or distribution and immediately after the
effective date in the case of a subdivision, combination or reclassification.

                If after an adjustment a holder of a Warrant upon exercise of it
may receive shares of two or more classes of capital stock of the Corporation,
the Corporation shall determine the allocation of the adjusted  Exercise Price
between the classes of capital stock.  After such allocation, the exercise
privilege and the Exercise Price of each class of capital stock shall thereafter
be subject to adjustments on terms comparable to those applicable to Common 
Stock in this Section.

                Such adjustment shall be made successively whenever any event
listed above shall occur.

                (b)  Adjustment for Rights Issue.

                If the Corporation distributes any rights, options or warrants
to all holders of its Common Stock entitling them for a period expiring within
60 days after the record date mentioned below to purchase shares of Common Stock
at a price per share less than the current market price per share on that record
date, the Exercise Price shall be adjusted in accordance with the formula.

                                                0 + (N x P)
                                                    -------
                                     E' = E  x         M
                                                    -------
                                                    O + N

where:

        E'  =  the adjusted Exercise Price.

        E   =  the current Exercise Price

        O   =  the number of shares of Common Stock outstanding on the record
               date.

        N   =  the number of additional shares of Common Stock offered.

        P   =  the offering price per share of the additional shares

        M   =  the current market price per share of the Common Stock on the
               record date.

                The adjustment shall be made successively whenever any such
rights, options or warrants are issued and shall become effective immediately
after the record date for the determination of stockholders entitled to receive
the rights, options or warrants.  If at the end of the period during which such
rights, options or warrants are exercisable, not all rights, options or warrants
shall have been exercised, the Exercise Price shall be immediately readjusted


                                       6.
<PAGE>   7
to what it would have been if "N" in the above formula had been the number of
shares actually issued.

         (c)   Adjustment for Other Distributions.

               If the Corporation distributes to all holders of its Common Stock
any of its assets (including but not limited to cash), debt securities,
preferred stock, or any rghts or warrants to purchase debt securities, preferred
stock, assets or other securities of the Corporation, the Exercise Price shall
be adjusted in accordance with the formula:

                             E' = E x M - F
                                      -----
                                        M

where:

         E'    =    the adjusted Exercise Price.

         E     =    the current Exercise Price.

         M     =    the current market price per share of Common Stock on the
                    record date mentioned below.

         F     =    the fair market value on the record date for the assets,
                    securities, rights or warrants applicable to one share of
                    Common Stock.  The Board of Directors shall determine the
                    fair market value.

                    The adjustment shall be made successively whenever any such
distribution is made and shall become effective immediately after the record
date for the determination of stockholders entitled to receive the distribution.

                    This subsection does not apply to rights, options or
warrants referred to subsection (b) of this Section 5.

         (d)   Adjustment for Common Stock Issue.

               If the Corporation issues shares of Common Stock for a
consideration per share less than the current market price per share on the date
the Corporation fixes the offering price of such additional shares, the Exercise
Price shall be adjusted in accordance with the formula:

                                          P
                                         ---
                             E' = E x O + M
                                      ------
                                          A

                                       7.
<PAGE>   8
where:

         E'    =    the adjusted Exercise Price.

         E     =    the then current Exercise Price

         O     =    the number of shares outstanding immediately prior to the
                    issuance of such additional shares.

         P     =    the aggregate consideration received for the issuance of
                    such additional shares.

         M     =    the current market price per share on the date of issuance
                    of such additional shares.

         A     =    the number of shares outstanding immediately after the
                    issuance of such additional shares.

                    The adjustment shall be made successively whenever any such
issuance is made, and shall become effective immediately after such issuance.

                     This subsection (d) does not apply to:

                     (1)    any of the transactions described in subsections (b)
         and (c) of this Section 5,

                     (2)    the exercise of a Warrant, or the conversion or
         exchange of other securities convertible or exchangeable for Common 
         Stock,

                     (3)    Common Stock issued to the Corporation's employees,
         directors or consultants under bone fide benefit plans adopted by the
         Board of Directors and approved by the holders of Common Stock when
         required by law, if such Common Stock would otherwise be covered by
         this subsection (d) (but only to the extent that the aggregate number
         of shares excluded hereby and issued after the date of this Warrant
         shall not exceed 10% of the Common Stock outstanding at the time of the
         adoption of each such plan, exclusive of antidilution adjustments
         thereunder).

                     (4)    Common Stock issued upon the exercise of rights or
         warrants issued to the holders of Common Stock,

                     (5)    Common Stock issued to shareholders of any person
         which merges into the Corporation in proportion to their stock holdings
         of such person immediately prior to such merger, upon such merger,

                                       8.
<PAGE>   9
                     (6)    Common Stock issued in a bona fide public offering
         pursuant to a firm commitment underwriting or

                     (7)    Common Stock issued in a bona fide private placement
         through a placement agent which is a member firm of the National
         Association of Securities Dealers, Inc. (except that any discount from
         the current market price attributable to restrictions on
         transferability of the Common Stock, as determined in good faith by the
         Board of Directors and described in a Board resolution which shall be
         delivered to the  Holder, shall exceed 20%).

         (e)   Adjustment for Convertible Securities Issue.

               If the Corporation issues any securities convertible into or
exchangeable for Common Stock (other than securities issued in transactions
described in subsections (b) and (c) of this Section 5) for a consideration per
share of Common Stock initially deliverable upon conversion or exchange of such
securities less than the current market price per share on the date of issuance
of such securities, the Exercise Price shall be adjusted in accordance with this
formula:
                                          P
                                         ---
                             E' = E x O + M
                                      ------
                                      O + D

where:

         E'    =    the adjusted Exercise Price.

         E     =    the then current Exercise Price

         O     =    the number of shares outstanding immediately prior to the
                    issuance of such securities.

         P     =    the aggregate consideration received for the issuance of
                    such securities.

         M     =    the current market price per share on the date of issuance
                    of such securities.

         D     =    the maximum number of shares deliverable upon conversion or
                    in exchange for such securities at the initial conversion or
                    exchange rate.

                    The adjustment shall be made successively whenever any such
issuance is made, and shall become effective immediately after such issuance.

                    If all of the Common stock deliverable upon conversion or
exchange of such securities have not been issued when such securities are no
longer outstanding, then the

                                       9.
<PAGE>   10
Exercise Price shall promptly be readjusted to the Exercise Price which would
then be in effect had the adjustment upon the issuance of such securities been
made on the basis of the actual number of shares of Common Stock issued upon
conversion or exchange of such securities.

              This subsection (e) does not apply to:

              (1)    convertible securities issued to shareholders of any person
         which merges into the Corporation, or with a subsidiary of the
         Corporation, in proportion to their stock holdings of such person
         immediately prior to such merger, upon such merger;

              (2)    convertible securities issued in a bona fide public 
         offering pursuant to a firm commitment underwriting; or

              (3)    convertible securities issued in a bona fide private
          placement through a placement agent which is a member firm of the
          National Association of Securities Dealers, Inc. (except to the extent
          that any discount from the current market price attributable to
          restrictions on transferability of Common Stock issuable upon
          conversion, as determined in good faith by the Board of Directors and
          described in a Board resolution which shall be delivered to the
          Holder, shall exceed 20% of the then current market price).

          (f) Current Market Price.

              In subsections (b), (c), (d) and (e) of this Section 5 the current
          market price per share of Common Stock on any date is the average of
          the Quoted Prices of the Common Stock for 30 consecutive trading days
          commencing 45 trading days before the date in question.  The "Quoted
          Price" of the Common Stock is the last reported sales price of the
          Common Stock as reported NASDAQ, National Market System, or if the
          Common Stock is listed or a securities exchange, the last reported
          sales price of the Common Stock on such exchange which shall be for
          consolidated trading if applicable to such exchange, or if neither so
          reported or listed the last reported bid price of the Common Stock.
          In the absence of one or more such quotations, the Board of Directors
          of the Corporation shall determine the current market price on the
          basis of such factors as it in good faith considers appropriate.

          (g) Consideration Received.

              For purposes of any computation respecting consideration received
         pursuant to subsections (d) and (e) of this Section 5, the following
         shall apply:

              (1)     in the case of the issuance of shares of Common Stock for
          cash, the consideration shall be the amount of such cash, provided
          that in no case shall any deduction be made for any commissions,
          discounts or other expenses incurred by the Corporation for any
          underwriting of the issue or otherwise in connection therewith;

                                      10.
<PAGE>   11
                 (2)      in the case of the issuance of shares of Common Stock
       for a consideration in whole or in part other than cash, the
       consideration other than cash shall be deemed to be the fair market value
       thereof as determined in good faith by the Board of Directors
       (irrespective of the accounting treatment thereof), whose determinations
       shall be conclusive, and described in a Board resolution;


                 (3)      in the case of the issuance of securities convertible
       into or exchangeable for shares, the aggregate consideration received
       therefor shall be deemed to be the consideration received by the
       Corporation for the issuance of such securities plus the additional
       minimum consideration, if any, to be received by the Corporation upon the
       conversion or exchange thereof (there consideration in each case to be
       determined in the same manner as provided in clauses (1) and (2) of this
       subsection).

       (h)       When De Minimis Adjustment Be Deferred.

                 No adjustment in the Exercise Price need to be made unless the
adjustment would require an increase or decrease of at least 1% in the Exercise
Price.  Any adjustments that are not made shall be carried forward and taken
into account in any subsequent adjustment.

                 All calculations under this Section shall be made to the
nearest cent or to the nearest 1/100th of a share, as the case may be.

       (i)       When No Adjustment Required.

                 No adjustment need be made for a transaction referred to in
subsections (a), (b), (c), (d) or (e) of this Section 5 if Warrant holders are
to participate in the transaction on a basis and which notice that the Board of
Directors determines to be fair and appropriate in light of the basis and notice
on which holders of Common Stock participate in the transaction.

                 No adjustment need be made for rights to purchase Common Stock
pursuant to a Corporation plan for reinvestment of dividends or interest.

                 No adjustment need be made for a change in the par value or no
par value of the Common Stock.

                 To the extent the Warrants become convertible into cash, no
adjustment need be made thereafter as to the cash.  Interest will not accrue on
the cash.

       (j)       Notices to Warrant Holder.  Upon any adjustment of the Exercise
Price pursuant to Section 5, the Corporation shall promptly thereafter (i) cause
to be filed with the Corporation a certificate of a firm of independent public
accountants of recognized standing selected by the Board of Directors of the
Corporation (who may be the regular

                                      11.

       auditors of the Corporation) setting forth the Exercise Price after such
       adjustment and setting forth in reasonable detail the method of
       calculation and the facts upon which such calculations are based an
       setting forth the number of Exercise Shares (or portion thereof) issuable
       after such adjustment in the Exercise Price, upon exercise of a Warrant
       and payment of the adjusted Exercise Price, which certificate shall be
       conclusive evidence of the correctness of the matters set forth therein,
       and (ii) cause to be given to each of the registered holders of the
       warrant certificates at his address appearing on the Warrant register
       written notice of such adjustments by first-class mail, postage prepaid.
       Where appropriate, such notice may be given in advance and included as a
       part of the notice required to be mailed under the other provisions of
       this Section 5 (j).

                  In case:

                                (1)       the Corporation shall authorize the
issuance to all holders of shares of Common Stock of rights, options or warrants
to subscribe for or purchase shares of Common Stock or of any other subscription
rights or warrants; or

                                (2)       the Corporation shall authorize the
distribution to all holders of shares of Common Stock of evidences of its
indebtedness or assets (other than cash dividends or cash distributions payable
out of consolidated earnings or earned surplus or dividends payable in shares of
Common Stock or distributions referred to subsection (a) of Section 5 hereof);
or

                                (3)       of any consolidation or merger to
which the Corporation is a party and for which approval of any shareholders of
the Corporation is required, or of the conveyance or transfer of the properties
and assets of the Corporation substantially as an entirety, or of any
reclassification or change of Common Stock issuable upon exercise of the Warrant
(other than a change in par value, or from par value to no par value, or from no
par value to par value, or as a result of a subdivision or combination), or a
tender offer or exchange offer for shares of Common Stock; or

                                (4)       of the voluntary or involuntary
dissolution, liquidation or winding up of the Corporation; or


                                (5)       the Corporation proposes to take any
action (other than actions of the character described in Section 5(a)) which
would require an adjustment of the Exercise Price pursuant to Section 5; then
the Corporation shall cause to be given to each of the registered holders of the
warrant certificates at his address appearing on the Warrant register, at least
20 days (or 10 days in any cased specified in clauses (a) or (b) above) prior to
the applicable record date hereinafter specified, or promptly in the case of
events for which there is no record date, by first-class mail, postage prepaid,
a written notice stating (i) the date as of which the holders of record of
shares of Common Stock to be entitled to receive any such rights, options,
warrants or distribution are to be determined, or (ii) the initial expiration
date set forth in any tender offer or exchange offer for shares of Common Stock,
or (iii) the date on which any such consolidation, merger, conveyance, transfer,
dissolution, liquidation or winding up is expected to become effective or
consummated, and the date as of which is its expected that holders of

                                      12.
<PAGE>   13
record of shares of Common Stock shall be entitled to exchange such shares for
securities or other property, if any, deliverable upon such reclassification,
consolidation, merger, conveyance, transfer, dissolution, liquidation or winding
up.  The failure to give the notice required by this Section 5(j) or any defect
therein shall not affect the legality or validity of any distribution, right,
option, warrant, consolidation, merger, conveyance, transfer, dissolution,
liquidation or winding up, or the vote upon any action.

           Nothing contained in this Warrant or in any of the warrant
certificates shall be construed as conferring upon the holders thereof the right
to vote or to consent or to receive notice as shareholders in respect of the
meetings of shareholders or the election of Directors of the Corporation or any
other matter, or any rights whatsoever as shareholders of the Corporation.

           (k)        Voluntary Reduction.

           The Corporation from time to time may reduce the Exercise Price by
any amount for any period of time if the period is at least 20 days and if the
reduction is irrevocable during the period; provided, however, that in no event
may the Exercise Price be less than the par value of a share of Common Stock.

            Whenever the Exercise Price is reduced, the Corporation shall mail
to Warrant holders a notice of the reduction.  The Corporation shall mail the
notice at least 15 days before the date the reduced Exercise Price takes
effect.  The notice shall state the reduced Exercise Price and the period it
will be in effect.

            A reduction of the Exercise Price does not change or adjust the
Exercise Price otherwise in effect for purposes of subsections (a), (b), (c),
(d) and (e) of this Section 5.

            (l)       Notice of Certain Transactions.

            If:

                      (1)     the Corporation takes any action that would
require an adjustment in the Exercise Price pursuant to subsections (a), (b),
(c), (d) or (e) of this Section 5 and if the Corporation does not arrange for
Warrant holders to participate pursuant to subsection (i) of this Section 5;

                      (2)      the Corporation takes any action that would
require a supplemental Warrant Agreement pursuant to subsection (m) of this
Section 5; or

                      (3)       there is a liquidation or dissolution of the
Corporation, the Corporation shall mail to Warrant holders a notice stating the
proposed record date for a dividend or distribution or the proposed effective
date of a subdivision, combination, reclassification, consolidation, merger,
transfer, lease, liquidation or dissolution.  The

                                      13.
<PAGE>   14
        Corporation shall mail the notice at least 15 days before such date.
        Failure to mail the notice or any defect in it shall not affect the
        validity of the transaction.

               (m)     Reorganization of Corporation.

               If the Corporation consolidates or merges with or into, or
transfers or leases all or substantially all its assets to, any person, upon
consummation of such transaction the Warrant shall automatically become
exercisable for the kind and amount of securities, cash or other assets which
the holder of a Warrant would have owned immediately after the consolidation,
merger, transfer or lease if the holder had exercised the Warrant immediately
before the effective date of the transaction.  Concurrently with the
consummation of such transaction, the corporation formed by or surviving any
such consolidation or merger if other than the Corporation, or the person to
which such sale or conveyance shall have been made, shall enter into a
supplemental Warrant Agreement so providing and further providing for
adjustments which shall be as nearly equivalent as may be practical to the
adjustments provided for in this Section.  The successor Corporation shall mail
to Warrant holders a notice describing the supplemental Warrant Agreement.

               If the issuer of securities deliverable upon exercise of Warrants
under the supplemental Warrant Agreement is an affiliate of the formed,
surviving, transferee of lessee corporation, that issuer shall join in the
supplemental Warrant Agreement.

               If this subsection (m) applies, subsections (a), (b), (c), (d),
and (e) of this Section 5 do not apply.

                (n)     Corporation Determination Final.

                Any determination that the Corporation or the Board of Directors
must make pursuant to subjection (a), (c), (d), (e), (f), (g) or (i) of this
Section 5 is conclusive.

                (o)     When Issuance or Payment Be Deferred.

                In any case in which the Section 5 shall require that an
adjustment in the Exercise Price be made effective as of a record date for a
specified event, the Corporation may elect to defer until the occurrence of such
event (i) issuing to the holder of any Warrant exercised after such record date
the Exercise Shares and other capital stock of the Corporation, if any, issuable
upon such exercise over and above the Exercise Shares and other capital stock of
the Corporation, if any, issuable upon such exercise on the basis of the
Exercise Price and (ii) paying to such  holder any amount in cash in lieu of a
fractional share pursuant to Section 6, provided, however, that the Corporation
shall deliver to such  holder a due bill or other appropriate instrument
evidencing such holder's right to receive such additional Exercise Shares, other
capital stock and cash upon the occurrence of the event requiring such
adjustment.

                                      14.
<PAGE>   15
        (p)  Adjustment in Number of Shares.

             Upon each adjustment of the Exercise Price pursuant to this 
Section 5 each Warrant outstanding prior to the making of the adjustment in the
Exercise Price shall thereafter evidence the right to receive upon payment of
the adjusted Exercise Price that number of shares of Common Stock (calculated to
the nearest hundredth) obtained from the following formula:

                                       N' = N x E
                                                -
                                                E'

where:

        N' =  the adjusted number of Exercise Shares issuable upon exercise of a
              Warrant by payment of the adjusted Exercise Price.

        N =   the number of Exercise Shares previously issuable upon exercise of
              a Warrant by payment of the Exercise Price prior to adjustment.

        E' =  the adjusted Exercise Price.

        E =   the Exercise Price prior to adjustment.

        This Section 5(p) shall terminate with respect to the adjustments
contemplated by Sections 5(d) and (e) upon the effective date of the initial
public offering of the Company's Common Stock.

        SECTION 6.  Fractional Shares.  No fractional shares shall be issued
upon the exercise of this Warrant as a consequence of any adjustment pursuant
hereto.  All Exercise Shares (including fractions) issuable upon exercise of
this Warrant may be aggregated for purposes of determining whether the exercise
would result in the issuance of any fractional share.  If, after aggregation,
the exercise would result in the issuance of a fractional share, the Corporation
shall, in lieu of issuance of any fractional share, pay the Holder otherwise
entitled to such fraction a sum in cash equal to the product resulting from
multiplying the then current fair market value of an Exercise Share by such
fraction.

        SECTION 7.  Obtaining Stock Exchange Listings.  The Corporation will
from time to time take all action which may be necessary so that the Exercise
Shares, immediately upon their issuance upon the exercise of the Warrant, will
be listed on the principal securities exchanges and markets within the United
States of America, if any, on which other shares of Common Stock are then
listed.

        SECTION 8.  No Stockholder Rights for Liability.  This Warrant in and of
itself shall not entitle the Holder to any voting rights or other rights as a
stockholder of the Corporation.  No provision hereof, in the absence of
affirmative action by the Holder to purchase the Exercise

                                      15.


























<PAGE>   16
Shares, and no emuneration herein of the rights or privileges of the Holder
shall give rise to any liability of the Holder as a shareholder of the
Corporation.

        SECTION 9.  Transfer of Warrant.  Subject to applicable laws and the
restriction on transfer set forth on the first page of this Warrant, this
Warrant and all rights hereunder are transferable, by the Holder in person or by
duly authorized attorney, upon delivery of this Warrant and the form of
assignment attached hereto to any transferee designated by Holder.  The
transferee shall sign an investment letter in form and substance satisfactory to
the Corporation.  Upon due presentation for registration of transfer of this
Warrant at the office of the Corporation a new Warrant of like tenor and
evidencing in the aggregate a like number of Exercise Shares shall be issued to
the transferee(s) in exchange for this Warrant, subject to the limitations
provided in this Warrant, without charge except for any tax or other
governmental charge imposed in connection therewith.

        SECTION 10.  Lost, Stolen, Mutilated or Destroyed Warrant.  If this
Warrant is lost, stolen, mutilated or destroyed, the Corporation may, on such
terms as to indemnity or otherwise as it may reasonably impose (which shall, in
the case of a mutilated Warrant, include the surrender thereof), issue a new
Warrant of like denomination and tenor as the Warrant so lost, stolen, mutilated
or destroyed.  Any such new Warrant shall constitute an original contractual
obligation of the Corporation, whether or not the allegedly lost, stolen,
mutilated or destroyed Warrant shall be at any time enforceable by anyone.

        SECTION 11.  Notices, etc.  All notices and other communications
thereunder shall be in writing and shall be deemed given if delivered
personally, or mailed by registered or certified mail (return receipt requested)
with postage prepaid, or sent by express courier service, to the parties at the
following address (or at such address for a Party as shall be specified by like
notice):.

        SECTION 13.  Governing Law.  All questions concerning the construction,
validity and interpretation of this Warrant and all issues concerning the
relative rights of the Corporation and holders of its securities shall be
governed by and construed in accordance with the laws of the State of California
as applied to contracts entered into and performed wholly within the State of
California.

        Section 14.  Amendments, Waiver, Etc.  This Warrant and any term hereof
may be changed, waived, discharged or terminated only by an instrument in
writing signed by the Holder and the Corporation.

stamp taxes attributable to the initial issuance of Exercise Shares upon the
exercise of the Warrant, provided, however, that the Corporation shall be
required to pay any tax or taxes which may be payable in respect of any transfer
involved in the issue of any warrant certificates or any certificates for
Exercise Shares in a name other than that of the registered holder of a warrant
certificate surrendered upon the exercise of a Warrant, and the Corporation
shall not be required to issue or deliver such warrant certificates unless or
until the person or persons requested the issuance thereof shall have to the
Corporation the amount of such tax or shall have established to the
satisfaction of the Corporation that such tax has been paid.

        Section 16.  Counterparts.  This Warrant may be executed in any number
of counterparts and each of such counterparts shall for all purposes be deemed
to be an original, and all such counterparts shall together constitute but one
and the same instrument.

        IN WITNESS WHEREOF, the Corporation has caused this Warrant to be

                              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 *************** 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.  FUNDING

        4.1  PROJECT INITIATION FEE.  To fund the performance by ALANEX of its
obligations under this Agreement, ASTRA will pay to ALANEX $250,000.00 after
the signing of this Agreement and prior to the initiation of the project. This
fee should be used to purchase equipment needed for the initiation of the
research program and is independent of FTE and milestone payments.

                                               *CONFIDENTIAL TREATMENT REQUESTED


         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 *********  for a
computational chemist, *************  for synthetic organic-medicinal
chemistry, and *********  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)
months. 

                          5. CONSULTATION AND REPORTS


        5.1 CONSULTATION. During the Term of the Agreement, ASTRA's
representatives may consult informally with ALANEX's representatives regarding
the Research Program, both personally and by telephone. Access to ASTRA work
carried on in ALANEX laboratories in the course of the Research Program shall
be made available to ASTRA during normal business hours upon reasonable notice.

                  2. LICENSING OF PATENT RIGHTS AND TECHNOLOGY

<PAGE>   19
                                              * CONFIDENTIAL TREATMENT REQUESTED

             The license granted herein shall, subject to third party rights,

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

obligations towards Licensor as those provided for herein.

                             3. MILESTONE PAYMENTS

        3.1  NOVO NORDISK's obligation to make milestone payments in accordance

                         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

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)
*************** 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 **********
****** the 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
                                          * CONFIDENTIAL TREATMENT REQUESTED

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

                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

SECTION 6  DEVELOPMENT

        6.1  SELECTION OF LEAD COMPOUNDS. Following the identification of a
Compound, the further optimization and characterization of such Compound and
the collection of data on such Compound, the Research Management Committee
shall determine whether such Compound satisfies the Preclinical Development
Criteria. The Research Management Committee shall notify Roche Bioscience in
writing when a Compound is determined to have satisfied the Preclinical
Development Criteria (the "RMC Notice"). Roche Bioscience shall have a 90-day
period beginning on the date of the RMC Notice in which to select such Compound
for development by providing written notice of such election to Alanex. If
Roche Bioscience selects such Compound, the Compound will then be considered a
Lead Compound for purposes of this Agreement and Roche Bioscience shall have
the exclusive license to such Lead Compound, its analogues, all
structurally-related compounds, and progenitors of the Lead Compound back to
and including the predecessor Compound, as contemplated by Section 7.2. If
Roche Bioscience does not select such Compound and if Roche Bioscience is not
developing a structurally-related compound on which Roche Bioscience will be
paying Milestones and Royalties under this Agreement, Alanex shall retain all
rights to such Compound; provided, however, that Alanex cannot conduct any
research with respect to or sublicense such Compound in the Field until
termination of this Collaboration. If Roche

        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 **** per month;
provided that in no event shall such rate exceed the maximum legal annual

         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

aspect of this Agreement, except with respect to disclosures required by law or
regulation. Within 30 days following the Effective Date, the Parties shall
issue a joint press release. Neither party shall use the name of the other
party in any public statement, prospectus, annual report, or press release
without the prior written approval of the other party, which may not be
unreasonably withheld or delayed, provided, however, that both parties shall
endeavor in good faith to give the other party a minimum of five business days
to review such press release, prospectus, annual report, or other public
statement; and provided, further, that either party may use the name of the
other party in any public statement, prospectus, annual report, or press
release without the prior written approval of the other party, if such party is

SECTION 15  DISPUTE RESOLUTION

        15.1  DISPUTES.  The Parties recognize that disputes as to certain
matters may from time to time arise during the term of this Agreement which
relate to either Party's rights and/or obligations hereunder or thereunder. It
is the objective of the Parties to establish procedures to facilitate the
resolution of disputes arising under this Agreement in an expedient manner by
mutual cooperation and without resort to litigation. To accomplish this

        For Alanex:                Chief Executive Officer

        15.3  ARBITRATION. Any such dispute arising out of or relating to this
Agreement which is not resolved between the Parties or the Research Management
Committee or the designated officers of the Parties pursuant to the foregoing
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.

SECTION 16    MISCELLANEOUS

Agreement shall be void.

        16.2  FORCE MAJEURE.  Neither Party shall lose any rights hereunder or

        16.7  WAIVER.  Except as specifically provided for herein, the waiver
from time to time by either of the Parties of any of their rights or their

provided in this Agreement.

        16.8  SEVERABILITY.  If any term, covenant or condition of this
Agreement or the application thereof to any Party or circumstance shall, to any

                    MATERIALS TRANSFER AND RESEARCH AGREEMENT

         This Agreement is made as of June 27, 1996 (the "EFFECTIVE DATE"), by
and between ALANEX CORPORATION, a California corporation having offices at 3550
General Atomics Court, San Diego, California 92121 (the "COMPANY") and ROCHE
BIOSCIENCE, a division of Syntex (USA), Inc., a Delaware corporation, having
offices at 3401 Hillview Avenue, Mail Stop R7-101, Palo Alto, California 94303
("ROCHE BIOSCIENCE"), with respect to the following:

         WHEREAS, the Company desires to transfer to Roche Bioscience, and Roche
Bioscience desires to receive, certain materials described in Exhibit A hereto
(the "MATERIALS") for the purpose of carrying out certain research (the
"RESEARCH") as more fully described in Section 5.1 of the Collaborative Research
and License Agreement between the Company and Roche Bioscience of even date
herewith.

         NOW THEREFORE, in consideration of the foregoing premises and the
mutual covenants set forth below, the Company and Roche Bioscience hereby agree
as follows:

         1. USE OF MATERIALS BY ROCHE BIOSCIENCE. Roche Bioscience shall use the
Materials solely for the purpose of carrying out the Research and shall not
attempt to reverse engineer, deconstruct or in any way determine the structure
or composition of the Materials. Roche Bioscience shall not sell, transfer,
disclose or otherwise provide access to the Materials to any person or entity
without the prior express written consent of the Company, except that Roche
Bioscience may allow access to the Materials to employees and agents for
purposes consistent with this Agreement provided that prior to such disclosure,
such individuals shall have been apprised of the proprietary nature of the
Materials and shall have executed written agreements consistent with the terms
hereof. Roche Bioscience will take all reasonable steps to ensure that such
employees and agents will use the Materials in a manner that is consistent with
the terms of this Agreement.

         2. CONDUCT OF RESEARCH. Upon receipt of the Materials, Roche Bioscience
shall perform the Research utilizing its expertise and facilities in strict
accordance with all applicable laws, regulations and guidelines, including
without limitation, those regulations and guidelines promulgated by the U.S.
Food and Drug Administration and the U.S. Department of Agriculture. Roche
Bioscience understands that the Materials may have biological and/or chemical
properties that are unpredictable and unknown at the time of transfer, that they
are to be used with caution and prudence, and are not to be used for testing in
or treatment of humans.

                                       1.
<PAGE>   2
         3. RESEARCH RESULTS. Roche Bioscience shall, in accordance with its
established practice, keep complete, accurate and authentic accounts, notes,
data and records of the Research performed under this Agreement. Roche
Bioscience shall promptly and fully disclose to the Company any and all
information, data and results obtained from conducting the Research or relating
to the use of the Materials (the "RESULTS"), which disclosure shall include,
without limitation, copies of relevant data, summaries and reports. Upon request
by the Company and in any event upon the conclusion of the Research, Roche
Bioscience shall prepare a summary report detailing the Results and the
underlying data, which report shall be delivered within thirty (30) days of the
termination of this Agreement. The Company shall have the right to use all such
Results for any purpose, including without limitation, referencing such Results
in any regulatory filings or patent applications. Roche Bioscience shall have
the right to use all such Results solely for research and other non-commercial
purposes.

         4. PROPRIETARY RIGHTS.

                  a. COMPANY PROPRIETARY RIGHTS. Roche Bioscience agrees and
acknowledges that Roche Bioscience shall acquire no rights of any kind
whatsoever with respect to any patents, copyrights, trademarks, trade secrets or
other proprietary rights of the Company as a result of Roche Bioscience's
performance under this Agreement or otherwise and that the Company is, and shall
remain at all times, the sole owner of the Materials and related know-how.

                  b. INVENTIONS IN THE COURSE OF RESEARCH. In performing the
Research, Roche Bioscience may develop ideas, inventions, techniques and other
technology and associated intellectual property, whether or not patentable
(collectively, "INVENTIONS"). The Company and Roche Bioscience agree that all
Inventions shall be owned by Roche Bioscience; provided, however, that if Roche
Bioscience fails to exercise its option pursuant to Section 5.2 of the
Collaborative Research and License Agreement, Roche Bioscience shall assign all
of its right, title and interest in and to such Inventions to the Company at the
end of the Option Period (as defined therein). Roche Bioscience shall promptly

                                               *CONFIDENTIAL TREATMENT REQUESTED

2.       CONDUCT OF THE RESEARCH PROGRAM

         (A) Sponsor hereby engages the services of Mount Sinai as an
independent contractor to conduct the Research Program in accordance with the
terms of this Agreement. Mount Sinai will use its best efforts to conduct the
Research Program. During the term of this Agreement, the Principal Investigator
will collaborate with Sponsor in the Field on an exclusive basis; he will not
consult, perform work or otherwise engage in activities in the Field with any
other for-profit entity. This provision shall not restrict in any manner the
Researchers' rights to engage in academic, non-commercial scientific discourse
regarding the Field, including applying to the federal government for grants.

         (B) The Principal Investigator shall exercise technical direction of

                                               *CONFIDENTIAL TREATMENT REQUESTED

payment shall be due on or before the date six (6) months from the Effective
Date. The parties agree that ******* of such amount shall be used directly in
the Research Program and the remainder constitutes institutional overhead at the
rate of ************************. Promptly upon receipt of such funding, Mount 
Sinai will commence Phase II of the Research Program as described on Exhibit A. 
If the above milestone is not achieved and Sponsor elects not to make the 
******* payment, this Agreement shall expire on the date six (6) months from the
Effective Date.

         (B) During Phase II of the Research Program, the Principal Investigator
shall make himself available to provide reasonable assistance to Sponsor in the
preparation of an application for an SBIR grant of approximately ******** 
relating to further research in the Field.

5.       SPONSOR'S PROGRAM; PHASE III

         Concurrently with the Research Program, Sponsor intends to perform
chemical synthesis and pharmacological testing of compounds to initiate studies
to discover novel small molecule GnRH receptor agonists or antagonists, using
cells transfected with DNA coding for the human GnRH receptor provided by Mount
Sinai. If Sponsor identifies a lead drug candidate, the parties anticipate that
they may wish to provide for further research to be carried out at Mount Sinai.
The parties currently envision that such research might require up to ******** 
in research funding for up to two years. Prior to the conclusion of the Research
Program established under this Agreement, the parties shall meet to discuss the
progress of the parties' efforts in this area and the need for further research
at Mount Sinai.

6.       REPORTS AND CONFERENCES

         (A) Mount Sinai agrees to keep complete and accurate scientific records
of the work conducted under the Research Program and to provide Sponsor, upon

                                   ARTICLE 3

                                 CONSIDERATION

         3.1   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. Such milestones shall include the
filing of an IND with the U.S. FDA, events during Phase I, II or III clinical
trials, and the filing or approval of an application for regulatory approval of
a Licensed Product. License fees, equity investments, at 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 3.1. If Alanex
receives consideration in a form other than cash, Alanex may pay Licensor
pursuant to this Section 3.1 either in kind or in cash based upon the fair
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
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

                                       3.

         5.1   TERM. This Agreement will commence as of the Effective Date and,
unless sooner terminated as provided in this Article 5, will expire upon the
later of (a) ten (10) years from first commercial sale of any Licensed Product
or (b) the date of expiration of the last-to-expire patent included in the
Licensed Patents.

         5.2   TERMINATION BY ALANEX. Alanex will have the right to terminate
this Agreement for any reason upon sixty (60) days prior written notice to
Licensor. In the event of material breach by Licensor, Alanex may elect to
terminate this Agreement upon sixty (60) days prior written notice or continue
this Agreement while pursuing its legal remedies, including the receipt of
damages related to such breach. Any damages finally awarded may, at Alanex's
option, be deducted from any payments owed to Licensor pursuant to Article 3
hereof.

         5.3   TERMINATION BY LICENSOR. Licensor will have the right to
terminate this Agreement, in addition to pursuing any remedies available under
law or in equity, upon sixty (60) days written notice to Alanex if Alanex is in
material breach of this Agreement, unless within such sixty (60) day period
Alanex cures such breach.

         5.4   EFFECT OF TERMINATION; SURVIVAL. Upon any termination of this
Agreement, Alanex will pay Licensor all accrued payments due Licensor through
the expiration or termination date and all licenses shall revert to Licensor.

and Articles 6 and 7 shall survive indefinitely.

                         INDEMNIFICATION AND INSURANCE

         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
expenses of litigation) incurred or imposed upon Indemnitees in connection with
any claims, suits, actions, demands or judgments resulting or arising out of the
development, distribution, possession, manufacture, use, sale or administration
of Licensed Products by Alanex, its Affiliates or sublicensees, or by any third
party. Alanex or its sublicensees agree to carry and keep in force commercial
general liability insurance of not less than $1 million per occurrence and $2
million in aggregate to cover liability for damages on account of bodily or
personal injury or death to any person or damage to property of any person. In
addition, Alanex or its sublicensees shall keep in force product liability
insurance of not less than $2 million per occurrence and $4 million in aggregate
prior to any commercial distribution of Licensed Products; provided, however,
such limits shall be increased if Licensor can demonstrate that higher amounts
are customary for businesses the size of Alanex or engaged in the business in
which Alanex is engaged. Licensor will be named as an additional insured on

                                       5.

<PAGE>   6
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 that all required coverage is in effect stating the limits
of such coverage. Such insurance shall be written to include coverage for any
claims incurred in connection with the matters which are the subject of this
Agreement regardless of when such claims are brought. Licensor shall promptly
notify Alanex of any claim for which Licensor may seek indemnification under
this Article 7. Alanex shall have the right to control the defense of such claim
and may enter into any settlement that does not adversely affect the rights of
Licensor. Licensor shall fully cooperate with Alanex in the defense of such
claim, with out-of-pocket costs reimbursed by Alanex as part of the
indemnification.

                         TECHNOLOGY RIGHTS AND TRANSFER


         2.1 LICENSE GRANT. Licensor hereby grants to Alanex an exclusive (even
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
noncommercial academic and educational purposes. Alanex may grant sublicenses
under such rights, provided that Licensor approves the identity of any
sublicensee that is not a "Fortune 500" pharmaceutical company or on Fortune
Magazine's comparable international list. Licensor shall not unreasonably
withhold or delay any such approval.

         Alanex acknowledges that the United States Government may retain
certain rights under 35 U.S.C. 200-212 with respect to the Licensed
Technologies. The license granted to Alanex hereunder is subject to such rights.
Alanex agrees to use its reasonable best efforts to cause Licensed Products to
be manufactured in the United States.

         2.2 UPDATES OF LICENSED TECHNOLOGIES. As reasonably requested by
Alanex, the Principal Investigation and Licensor shall update Alanex as to
Licensed Patents and Licensed Know-how developed in the course of the Research
Program. Exhibit A shall be periodically updated by the parties to include all
such Licensed Patents and Licensed Know-how. Such list

shall be maintained for convenience only. The definitions set forth in Sections
1.2 and 1.3 shall define the Licensed Know-how and Licensed Patents covered by
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
Licensor within such thirty (30) day period that Alanex will not be responsible
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
awarded to Alanex in any suit for infringement, such damages shall be applied
first to reimburse Alanex for its enforcement expenses and the remainder will be
treated as Net Sales of Alanex subject to royalties under Section 3.3. In the
event that Alanex declines


                                       4.
<PAGE>   5
to prosecute infringement of any Licensed Patents pursuant to this Section 4.2,
Licensor shall have the right to prosecute such infringement at its own expense
and to retain any recovery obtained in such action.

         4.3 ASSISTANCE. Licensor shall provide any assistance reasonably
requested by Alanex in exercising its rights under this Article 4, subject to
reimbursement of Licensor's out-of-pocket costs in providing such assistance.
Without limitation, to the extent possible Licensor will execute any documents
necessary for Alanex to bring suit to enforce the Licensed Patents and will make
employees and other personnel associated with Licensor reasonably available to
assist with patent prosecution or to give testimony relating to the Licensed
Patents.

understanding, oral or written, to which it is a party or by which it may be
bound, nor violate any law or regulation of any court, governmental body or
administrative or other agency having jurisdiction over it.

Agreement for any reason upon sixty (60) days prior written notice to Licensor.
In the event of material breach by Licensor, Alanex may elect to terminate this
Agreement upon sixty (60) days prior written notice or continue this Agreement
while pursuing its legal remedies, including the receipt of damages related to
such breach. Any damages finally awarded may, at Alanex's option, be deducted
from any payments owed to Licensor pursuant to Article 3 hereof.

         6.3 TERMINATION BY LICENSOR. Licensor will have the right to terminate
this Agreement, in addition to pursuing any remedies available under law or in
equity, upon sixty (60) days written notice to Alanex if Alanex is in material
breach of this Agreement, unless


                                       5.
<PAGE>   6
within such sixty (60) day period Alanex initiates good faith efforts reasonably
calculated to cure such breach.

         6.4  EFFECT OF TERMINATION; SURVIVAL. Upon any termination of this
Agreement, Alanex will pay Licensor all accrued payments due Licensor through
the expiration or termination date and all licenses shall revert to Licensor.

following termination.


                                    ARTICLE 7

                                 CONFIDENTIALITY

         7.1  CONFIDENTIALITY.

              (a)  For purposes of this Agreement, "Confidential Information"
means any information or material disclosed or provided by Alanex to Licensor
pursuant to Article 3 or 4 of this Agreement, except:

                   (1)  information that is known to or independently developed
by Licensor prior to the time of disclosure, as evidenced by Licensor's records;

                   (2)  information disclosed to Licensor by a third party that

                   (3)  information that becomes patented, published or

or

                   (4)  information that is required to be disclosed by law.

              (b)  Licensor shall, for the term of this Agreement, maintain
Confidential Information in confidence and shall not disclose Confidential
Information to any third party or use Confidential Information for any purpose
not contemplated under this Agreement, except with the written consent of
Alanex.

         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
expenses of litigation) incurred or imposed upon Indemnitees in connection with
any claims, suits, actions, demands or judgments resulting or arising out of the
development, distribution, possession, manufacture, use, sale or administration
of Licensed Products by Alanex, its affiliates or sublicensees, or by any third
party. Alanex or its

sublicensees agree to carry and keep in force general commercial liability
insurance of not less than $1 million per occurrence and $2 million in aggregate

to any person or damage to property of any person. In addition, Alanex or its
sublicensees shall keep in force product liability insurance of not less than $2
million per occurrence and $4 million in aggregate prior to any commercial
distribution of Licensed Products; provided, however, such limits shall be
increased if Licensor can demonstrate that higher amounts are customary for
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
that all required coverage is in effect stating the limits of such coverage.
Such insurance shall be written to include coverage for any claims incurred in
connection with the matters which are the subject of this Agreement regardless

                    TERM WCMA(R) LOAN AND SECURITY AGREEMENT

This Term WCMA Loan and Security Agreement ("Loan Agreement") is entered into
as of June 6, 1994, between ALANEX CORPORATION, a corporation organized and
existing under the laws of the State of California having its principal office
at 3550 General Atomics Court, San Diego, CA 92121 ("Customer"), and MERRILL
LYNCH BUSINESS FINANCIAL SERVICES INC., a corporation organized and existing
under the laws of the State of Delaware having its principal office at 33 West
Monroe Street, Chicago, IL 60603 ("MLBFS").

In accordance with that certain Working Capital Management(R) Account Agreement
No. 232-07A39 ("WCMA Agreement") between Customer and MLBFS' affiliate, Merrill
Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), Customer has subscribed
to the WCMA Program described in the WCMA Agreement.  The WCMA Agreement is by
this reference incorporated as a part hereof.  In conjunction therewith,
Customer has requested that MLBFS make the Term WCMA Loan hereinafter described
(the "Loan"); and, subject to the terms and conditions herein set forth, MLBFS
has agreed to make the Loan to Customer.

The Loan combines the equivalent of 5 successive one-year term loans, each
equal to that portion of the Loan that will be fully amortized in one year,
with a line of credit under the WCMA Program ("WCMA Line of Credit") equal to
that portion of the Loan that will not be amortized in the ensuing year.
Subject to the terms hereof, each year after the initial funding there will be
an additional funding on account of the term portion of the Loan, with the
proceeds deposited into Customer's WCMA Account concurrently with a
corresponding reduction in the maximum WCMA Line of Credit.

This structure provides Customer with substantially the same funding and
amortization as a conventional term loan.  However, unlike most conventional
term loans, it permits both a prepayment in whole or in part at any time
without penalty, and subject to the terms and conditions herein set forth, a
re-borrowing on a revolving basis of any such amounts prepaid on account of the
WCMA Line of Credit portion of the Loan.  The structure therefore enables
Customer at its option to use its free cash balances to reduce term loan
interest expense without impairing working capital.

Accordingly, and in consideration of the premises and of the mutual covenants
of the parties hereto, Customer and MLBFS hereby agree as follows:

                            ARTICLE I.  DEFINITIONS

1.1  SPECIFIC TERMS.  In addition to terms defined elsewhere in this Loan
Agreement, when used herein the following terms shall have the following

                             ARTICLE II.  THE LOAN

2.1  COMMITMENT.  Subject to the terms and conditions hereof, MLBFS hereby
agrees to make the Loan to Customer, and Customer hereby agrees to borrow the
Loan from MLBFS.  Unless otherwise hereafter agreed by MLBFS, the entire
proceeds of the Loan will be disbursed either directly to the applicable third
party or parties on account of the Loan Purpose or to reimburse Customer for
amounts directly expended by it; all as directed by Customer in a Closing
Certificate to be executed and delivered to MLBFS prior to the date of funding.

2.2  OPERATION OF LOAN.

(a) The Loan will be evidenced by and shall be repayable in accordance with the
terms of the Term WCMA Note and this Loan Agreement.  The Term WCMA Note
combines two promissory notes, one evidencing the term portion of the Loan (the
"Term Note") and the other evidencing the WCMA Line of Credit portion of the
Loan (the "WCMA Note").  The balance owing by Customer on account of the Loan
at any time shall be an amount equal to the sum of the then outstanding
balances under the WCMA Note and the Term Note included in the Term WCMA Note.
The Term WCMA Note is hereby incorporated as a part hereof.

(b) The principal balance owing under the Term Note at any time shall be an
amount equal to the difference between (i) the Loan Amount less the aggregate
principal paid by Customer on account of the Term Note; and (ii) the WCMA Line
of Credit.  So long as there shall be any moneys owing by Customer to MLBFS
hereunder or there shall be a WCMA Line of Credit, no reduction in the unpaid
principal balance of the Term Note to zero shall be deemed a payment of the
Term Note in full or an extinguishment of any of the obligations of Customer
thereunder or hereunder.


                                      -3-
<PAGE>   4
(c) Subject to the terms hereof, the Term Note will be funded by MLBFS in 5
annual installments, each equal to 1/5th of the Loan Amount.  The first 1/5th
installment funded by MLBFS will be funded on the Closing Date and applied on
account of the Loan Purpose, as aforesaid.  Subsequent installments will be
funded on a date chosen by MLBFS in its sole discretion which will be on or
within two weeks before or after each subsequent anniversary of the last day of
the calendar month in which the Closing Date occurs (each, a "Subsequent
Funding Date").  Each Term Note funding after the first shall be deposited into
Customer's WCMA Account.

(d) On the Closing Date, MLBFS will activate and make available as an integral
part of the Loan a WCMA Line of Credit equal to 4/5ths of the Loan Amount, all
of which will be immediately disbursed on account of the Loan Purpose as part
of the Loan in accordance with the directions of Customer set forth in the
Closing Certificate, as aforesaid.

(e) On the first Subsequent Funding Date, concurrently with MLBFS' funding of
the second installment of the debt evidenced by the Term Note into the WCMA
Account, the WCMA Line of Credit will be reduced to an amount equal to 3/5ths
of the Loan Amount.  On the second Subsequent Funding Date, the WCMA Line of
Credit will be reduced to an amount equal to 2/5ths of the Loan Amount; and on
the third Subsequent Funding Date the WCMA Line of Credit will be reduced to an
amount equal to 1/5th of the Loan Amount.

(f) On the fourth Subsequent Funding Date (the "WCMA Maturity Date"), the WCMA
Line of Credit will be terminated and the WCMA Account, at the option of
Customer, will either be converted to a WCMA Cash Account (subject to any
requirements of MLPF&S) or terminated.

2.3  CONDITIONS OF MLBFS' OBLIGATION.  The Closing Date and MLBFS' obligation
to make the Loan on the Closing Date are subject to the prior fulfillment of
each of the following conditions: (a) MLBFS shall have received a written
request from Customer that the Loan be funded in accordance with the terms
hereof, together with a written direction from Customer as to the method of
payment and payee(s) of the proceeds of the Loan, which request and direction
shall have been received by MLBFS not less than two Business Days prior to any
requested funding date; (b) MLBFS shall have received a copy of invoices, bills
of sale, payoff letters or other applicable evidence reasonably satisfactory to
it that the proceeds of the Term Loan will satisfy the Loan Purpose; (c) the
Commitment Fee shall have been paid in full; (d) the Commitment Expiration Date
shall not then have occurred; and (e) each of the General Funding Conditions
shall have been met or satisfied to the reasonable satisfaction of MLBFS.

2.4  CONDITIONS OF SUBSEQUENT FUNDINGS; TERMINATION.

(a) The obligation of MLBFS to fund installments of the term portion of the
Loan on any Subsequent Funding Date shall be subject to each of the conditions
specified in Section 2.3 hereof being met at such date, and the further
condition that all payments due under the Term Note on or prior to any
Subsequent Funding Date shall have been paid in full; provided, however, that
notwithstanding the failure of any such conditions to have been met, MLBFS may
in its sole discretion fund such installment and/or any other installments, and
no such funding shall constitute a waiver by MLBFS of any of its rights
hereunder or under any of the Additional Agreements.  Without limiting the
foregoing, it is understood that no funding by MLBFS of any sum hereunder while
an Event of Default shall have occurred and is continuing shall under any
circumstances be deemed a waiver by MLBFS of such Event of Default, or a waiver
of any of MLBFS' rights hereunder.

(b) Notwithstanding anything herein or in any of the Additional Agreements to
the contrary, if at any time after the Closing Date there shall not be a
balance outstanding under either the WCMA Note or Term Note included in the
Term WCMA Note, then either Customer or MLBFS may at its respective option
terminate the Loan.  Following any such termination, MLBFS shall be relieved of
all further obligations with respect to the Loan and WCMA Line of Credit.


                                      -4-
<PAGE>   5
2.5 COMMITMENT FEE.  In consideration of the agreement by MLBFS to extend the
Loan to Customer in accordance with and subject to the terms hereof, Customer
has paid or shall, on or before the Closing Date pay, the Commitment Fee to
MLBFS.  The Commitment Fee shall not be refundable under any circumstances.

2.6 ACKNOWLEDGEMENT OF CUSTOMER.  Customer acknowledges, covenants and agrees
that:

(a) PAYMENT OF WCMA INTEREST; ADDITIONAL DEPOSITS.  Under the terms of this Loan
Agreement, interest accrued on amounts outstanding on the Term WCMA Line of
Credit each month will, subject to the terms hereof, ordinarily be paid from the
proceeds of a borrowing of an additional sum under the Term WCMA Line of Credit.
Since substantially the entire Term WCMA Line of Credit may be drawn on the
Closing Date, CUSTOMER AGREES THAT IT WILL, WITHOUT DEMAND, INVOICING OR THE
REQUEST OF MLBFS, FROM TIME TO TIME MAKE SUFFICIENT DEPOSITS INTO THE WCMA
ACCOUNT IN ORDER TO ASSURE THAT THE MAXIMUM WCMA LINE OF CREDIT IS NOT
EXCEEDED.  Installments of principal and interest under the Term Note shall be
paid directly to MLBFS in accordance with the terms of the Term Note.

(b) ADDITIONAL INTEREST CHARGES.  SUBJECT TO THE TERMS HEREOF, ON EACH
SUBSEQUENT FUNDING DATE MLBFS WILL DEPOSIT THE AMOUNT FUNDED INTO THE WCMA
ACCOUNT.   DUE TO POSSIBLE DELAYS IN POSTING AS WELL AS CERTAIN DELAYS IN
RECOGNITION OF DEPOSITS INHERENT IN THE WCMA PROGRAM, CUSTOMER WILL NOT RECEIVE
CREDIT FOR THE AMOUNT DEPOSITED FOR UP TO SEVERAL DAYS THEREAFTER, RESULTING IN
AN INTEREST CHARGE FOR THAT PERIOD OF TIME ACCRUING AND CHARGED IN THE WCMA
ACCOUNT.  ON THE OTHER HAND, BECAUSE MLBFS BORROWS ALL OR SUBSTANTIALLY ALL OF
THE FUNDS THAT IT LENDS ON THE DATE OF FUNDING, IT MUST CHARGE INTEREST ON THE
AMOUNT FUNDED ON EACH SUBSEQUENT FUNDING DATE FROM THE DATE OF ITS DEPOSIT INTO
THE WCMA ACCOUNT, WHETHER OR NOT SUCH DEPOSIT IS IMMEDIATELY RECOGNIZED.  THE
TIMING DIFFERENCES BETWEEN THE DATE OF DEPOSIT AND DATE OF RECOGNITION OF THE
DEPOSIT IN THE WCMA ACCOUNT WILL THEREFORE RESULT IN EXTRA INTEREST CHARGES TO
CUSTOMER, WHICH ACKNOWLEDGES ARE AN ADDITIONAL COST OF THE LOAN AND HEREBY
UNCONDITIONALLY AGREES TO PAY.

                     ARTICLE III.  THE WCMA LINE OF CREDIT

3.1 WCMA NOTE.

All amount owing under the WCMA Line of Credit shall be deemed owing under and
evidenced by the WCMA Note included in the Term WCMA Note.

3.2 WCMA LOANS.

(a) LOAN COMMITMENT AND REQUESTS.  Subject to the terms and conditions hereof:
(i) on the Closing Date, MLBFS will make a WCMA Loan to Customer in an amount
equal to the Maximum WCMA Line of Credit, the entire proceeds of which will be
disbursed on account of the Loan Purpose, as aforesaid; and (ii) during the
period from and after the Closing Date to the WCMA Maturity Date: (x) Customer
may repay said WCMA Loan and any other WCMA Loans in whole or in part at any
time without premium or penalty, and request a re-borrowing of amounts repaid
on a revolving basis, and (y) MLBFS will make such additional WCMA Loans as
Customer may from time to time request in accordance with the terms hereof,
provided that without limiting any of the other conditions hereof, the making
of any such WCMA Loan shall not cause the WCMA Loan Balance to exceed the
Maximum WCMA Line of Credit.  Customer may request WCMA Loans by use of WCMA
Checks, FTS, Visa(R) charges, wire transfers, or such other means of access to
the WCMA Line of Credit as may be permitted by MLBFS from time to time; it
being understood that so long as the WCMA Line of Credit shall be in effect,
any change or debit to the WCMA Account which but for the WCMA Line of Credit
would under the terms of the WCMA Agreement result in an overdraft, shall be
deemed a request by Customer for a WCMA Loan.



                                      -5-
<PAGE>   6
(b) CONDITIONS OF WCMA LOANS.  Notwithstanding the foregoing, MLBFS shall not
be obligated to make any WCMA Loan, and may without notice refuse to honor any
such request by Customer, if at the time of Customer's request: (i) the making
of such WCMA Loan would cause the Maximum WCMA Line of Credit to be exceeded;
or (ii) the Maturity Date shall have occurred, or the WCMA Line of Credit
shall have otherwise been terminated in accordance with the terms hereof; or
(iii) an event shall have occurred and is continuing which shall have caused
any of the General Funding Conditions to not then be met or satisfied to the
reasonable satisfaction of MLBFS.  The making by MLBFS of any WCMA Loan at a
time when any one or more of said conditions shall not have been met shall not
in any event be construed as a waiver of said condition or conditions or of any
Event of Default, and shall not prevent MLBFS at any time thereafter while any
condition shall not have been met from refusing to honor any request by
Customer for a WCMA Loan.

(c) FORCE MAJEURE.  MLBFS shall not be responsible, and shall have no liability
to Customer or any other party, for any delay or failure of MLBFS to honor any
request of Customer for a WCMA Loan or any other act or omission of MLBFS,
MLPF&S or any of their affilliates due to or resulting from any system failure,
error or delay in posting or other clerical error, loss of power, fire, Act of
God or other cause beyond the reasonable control of MLBFS, MLPF&S or any of
their affiliates unless directly arising out of the willful wrongful act or
active gross negligence of MLBFS. In no event shall MLBFS be liable to Customer
or any other party for any incidental or consequential damages arising from any
act or omission by MLBFS, MLPF&S or any of their affiliates in connection with
the WCMA Line of Credit or this Loan Agreement.

(d) INTEREST.  The WCMA Loan Balance shall bear interest at the Interest Rate.
Interest shall be computed for the actual number of days elapsed on the basis of
a year consisting of 360 days.  Notwithstanding any other provision in this Loan
Agreement or any Additional Agreements to the contrary, in no event shall the
Interest Rate exceed the highest rate permissible under any applicable law.  In
the event that any court having jurisdiction determines that MLBFS has received
excess interest hereunder, MLBFS will promptly refund such excess interest to
Customer, without charge or penalty.  Except as otherwise provided herein,
accrued and unpaid interest on the WCMA Loan Balance shall be payable monthly on
the last Business Day of each calendar month, commencing with the last Business
Day of the calendar month in which the Closing Date shall occur.  Customer
hereby irrevocably authorizes and directs MLPF&S to pay MLBFS such accrued
interest from any available free credit balances in the WCMA Account, and if
such available free credit balances are insufficient to satisfy any interest
payment due, to liquidate any investments in the Money Accounts (other than any
investments constituting any Minimum Money Accounts Balance) in an amount up to
the balance of such accrued interest, and pay to MLBFS the available proceeds on
account thereof.  If available free credit balances in the WCMA Account and
available proceeds of the Money Accounts are insufficient to pay the entire
balance of accrued interest, and Customer otherwise fails to make such payment
when due, MLBFS may, in its sole discretion, make a WCMA Loan in an amount equal
to the balance of such accrued interest and pay the proceeds of such WCMA Loan
to itself on account of such interest.  The amount of any such WCMA Loan will be
added to the WCMA Loan Balance.  If MLBFS declines to extend a WCMA Loan to
Customer under these circumstances, Customer hereby authorizes and directs
MLPF&S to make all such interest payments to MLBFS from any Minimum Money
Accounts Balance.  If there is no Minimum Money Accounts Balance, or it is
insufficient to pay all such interest, MLBFS will invoice Customer for payment
of the balance of the accrued interest, and Customer shall pay such interest as
directed by MLBFS within 5 business Days of receipt of such invoice.

(e) PAYMENTS.  All payments required or permitted to be made pursuant to this
Loan Agreement shall be made in lawful money of the United States.  Unless
otherwise directed my MLBFS, payments on account of the WCMA Loan Balance may be
made by the delivery of checks (other than WCMA Checks), or by means of FTS or
wire transfer of funds (other than funds from the WCMA Line of Credit) to MLPF&S
for credit to Customer's WCMA Account.  Notwithstanding anything in the WCMA
Agreement to the contrary, Customer hereby irrevocably authorizes and directs
MLPF&S to apply available free credit balances in the WCMA Account to the
repayment of the WCMA Loan Balance prior to application for any other purpose.
Payments to MLBFS from funds in the WCMA Account shall be deemed to be made by
Customer upon the same basis and schedule as funds are made available for
investment in the Money Accounts in accordance with the terms of the WCMA
Agreement.  The acceptance by or on behalf of MLBFS of a check or other payment
for a lesser amount than shall be due from Customer, regardless of any
endorsement or statement thereon or 



                                      -6-
<PAGE>   7
transmitted therewith, shall not be deemed an accord and satisfaction or
anything other than a payment on account, and MLBFS or anyone acting on behalf
of MLBFS may accept such check or other payment without prejudice to the rights
of MLBFS to recover the balance actually due or to pursue any other remedy under
this Loan Agreement or applicable law for such balance. All checks accepted by
or on behalf of MLBFS in connection with the Loan and WCMA Line of Credit are
subject to final collection.

(f) EXCEEDING THE MAXIMUM WCMA LINE OF CREDIT. In the event that the WCMA Loan
Balance shall at any time exceed the Maximum WCMA Line of Credit, Customer shall
within 2 Business Days of the first to occur of (i) any request or demand of
MLBFS, or (ii) receipt by Customer of a statement from MLPF&S showing a WCMA
Loan Balance in excess of the WCMA Line of Credit, deposit sufficient funds into
the WCMA Account to reduce the WCMA Loan Balance below the Maximum WCMA Line of
Credit.

(g) STATEMENTS. MLPF&S will include in each monthly statement it issues under
the WCMA Program information with respect to WCMA Loans and the WCMA Loan
Balance. Any questions that Customer may have with respect to such information
should be directed to MLBFS; and any questions with respect to any other matter
in such statements or about or affecting the WCMA Program should be directed to
MLPF&S.

otherwise, shall be deemed an assumption by MLBFS of any of Customer's said
obligations.

(d) ALTERATIONS AND MAINTENANCE.  Except upon the prior written consent of
MLBFS, Customer shall not make or permit any material alterations to any
Collateral which might materially reduce or impair its market value or utility.
Customer shall at all times keep the Collateral in good condition and repair and
shall pay or cause to be paid all obligations arising from the repair and
maintenance of such Collateral, as well as all obligations with respect to the
premises where any Collateral is or may be located, except for any such
obligations being contested by Customer in good faith by appropriate
proceedings.

(e) LOCATION.  Except for movements required in the ordinary course of
Customer's business, Customer shall give MLBFS 30 days' prior written notice of
the placing at or movement of any Collateral to any location other than a
Location of Collateral.  In no event shall Customer cause or permit any
Collateral to be removed from the United States without the prior written
consent of MLBFS.

(f) INSURANCE.  Customer shall insure all of the Collateral under a policy or
policies of physical damage insurance providing that losses will be payable to
MLBFS as its interests may appear pursuant to a Lender's Loss Payable
Endorsement and containing such other provisions as may be reasonably required
by MLBFS.  Customer shall further provide and maintain a policy or policies or
comprehensive public liability insurance naming MLBFS as an additional party
insured.  Customer and each Business Guarantor shall maintain such other
insurance as may be required by law or is customarily maintained by companies
in a similar business or otherwise reasonably required by MLBFS.  All such
insurance shall provide that MLBFS will receive not less than 10 days prior
written notice of any cancellation, and shall otherwise be in form and amount
and with an insurer or insurers reasonably acceptable to MLBFS.  Customer shall
furnish MLBFS with a copy or certificate of each such policy or policies and,
prior to any expiration or cancellation, each renewal or replacement thereof.

(g) EVENT OF LOSS.  Customer shall at its expense promptly repair all
repairable damage to any Collateral.  In the event that any Collateral is
damaged beyond repair, lost, totally destroyed or confiscated (an "Event of
Loss") and such Collateral had a value prior to such Event of Loss of
$25,000.00 or more, then, on or before the first to occur of (i) 90 days after
the occurrence of such Event of Loss, or (ii) 10 Business Days after the date
on which either Customer or MLBFS shall receive any proceeds of insurance on
account of such Event of Loss, or any underwriter of insurance on such
Collateral shall advise either Customer or MLBFS that it disclaims liability in
respect of such Event of Loss, Customer shall, at Customer's option, either
replace the Collateral subject to such Event of Loss with comparable Collateral
free of all liens other than Permitted Liens, or, in absence of insurance
payment, as reasonably determined by MLBFS.  Notwithstanding the foregoing, if
at the time of occurrence of such Event of Loss or any time thereafter prior to
replacement or prepayment, as aforesaid, an Event of Default shall occur
hereunder, then MLBFS may at its sole option, exercisable at any time while
such Event of Default shall be continuing, require Customer to either replace
such Collateral or prepay the Loan, as aforesaid.  Any prepayment of the Loan
pursuant to this Section shall be applied first to installments on account of
the then "Term Note Balance" (as defined in the Term WCMA Note) in inverse
order of maturity; with any prepayment in excess of the then Term Note Balance
applied on account of the WCMA Note concurrently with: (i) a like permanent
reduction in the WCMA Line of Credit, and (ii) a like reduction in the
obligation of MLBFS to fund future installments on account of the Term Note in
inverse order of funding.  No amount prepaid pursuant to this Section may be
re-borrowed by Customer.


                                      -10-
<PAGE>   11
(h)  NOTICE OF CERTAIN EVENTS.  Customer shall give MLBFS immediate notice of
any attachment, lien, judicial process, encumbrance or claim affecting or
involving $25,000.00 or more of the Collateral.

(i)  INDEMNIFICATION.  Customer shall indemnify, defend and save MLBFS harmless
from and against any and all claims, liabilities, losses, costs and expenses
(including, without limitation, reasonable attorneys' fees and expenses) of any
nature whatsoever which may be asserted against or incurred by MLBFS arising
out of or in any manner occasioned by (i) the ownership, possession use or
operation of any Collateral, or (ii) any failure by Customer to perform any of
its obligations hereunder; excluding, however, from said indemnity any such
claims, liabilities, etc. arising directly out of the willful wrongful act or
active gross negligence of MLBFS.  This indemnity shall survive the expiration
or termination of this Loan Agreement as to all matters arising or accruing
prior to such expiration or termination.

4.5  EVENTS OF DEFAULT.

The occurrence of any of the following events shall constitute an "Event of
Default" under this Loan Agreement: (a) Customer shall fail to pay when due any
amount owing by Customer to MLBFS under the Note or this Loan Agreement, and
such failure shall continue for more than 5 Business Days after written notice
thereof shall have been given by MLBFS to Customer; or (b) Customer or any
Guarantor shall default in the performance or observance of any covenant or
agreement on its part to be performed or observed under this Loan Agreement or
any of the Additional Agreements (not constituting an Event of Default under
any other clause of this Paragraph), and such default shall continue unremedied
for 10 Business Days after written notice thereof shall have been given by
MLBFS to Customer; or (c) any representation or warranty made by Customer or
any Guarantor contained in this Loan Agreement or any of the Additional
Agreements shall at any time prove to have been incorrect in any material
respect when made; or (d) a default or Event of Default by Customer or any
Guarantor shall occur under the terms of any other agreement, instrument or
document with or intended for the benefit of MLBFS, MLPF&S or any of their
affiliates, and any required notice shall have been given and required passage
of time shall have elapsed; or (e) a proceeding under any bankruptcy,
reorganization, arrangement, insolvency, readjustment of debt or receivership
law or statute shall be filed by Customer or any Guarantor, or any such
proceeding shall be filed against Customer or any Guarantor and shall not be
dismissed or withdrawn within 60 days after filing, or Customer or any
Guarantor shall make an assignment for the benefit of creditors, or Customer or
any Guarantor shall become insolvent or generally fail to pay, or admit in
writing its inability to pay, its debts as they become due; or (f) any event
shall occur which shall reasonably cause MLBFS to in good faith believe that
the prospect of payment or performance by Customer or any Guarantor has been
materially impaired; or (g) any event shall occur which results in the
acceleration of the maturity of any indebtedness of $100,000.00 or more of
Customer or any Guarantor to another creditor under any indenture, agreement,
undertaking, or otherwise; or (h) the Collateral, or any material part thereof,
shall be or become subject to any material abuse or misuse, or any levy,
attachment, seizure or confiscation which is not released within 10 Business
Days.

4.6  REMEDIES.

(a)  REMEDIES UPON DEFAULT.  Upon the occurrence and continuance of any Event
of Default: (i) MLBFS may terminate the Loan and WCMA Line of Credit without
notice, and upon any such termination MLBFS shall be relieved of any further
obligation to make the Loan (if any portion of the Loan has not then been
funded), or fund any further amount on account of the Term Note, or make or
continue to make the WCMA Line of Credit available to Customer, or otherwise
extend any credit to or for the benefit of Customer; and (ii) MLBFS may declare
the principal of and interest on the Term Note and WCMA Note included in the
Term WCMA Note, and all other Obligations to be forthwith due and payable,
whereupon all such amounts shall be immediately due and payable, without
presentment, demand, protest or other notice of any kind, all of which are
hereby expressly waived; and (iii) MLBFS may exercise any or all of the
remedies of a secured party under applicable law, including, but not limited to,
the UCC, and any or all of its other rights and remedies under this Loan
Agreement, the Term WCMA Note and the other Additional Agreements; and (iv)
MLBFS may require Customer to make the Collateral and the records pertaining to
the Collateral available to MLBFS at a place designated by MLBFS which is
reasonably convenient or may take possession of the Collateral and the records
pertaining to the Collateral without the use of any judicial process and
without any prior notice to Customer, and (v) MLBFS may sell any or all of the
Collateral at public or private sale upon



                                      -11-
<PAGE>   12
such terms and conditions as MLBFS may reasonably deem proper, and MLBFS may
purchase any Collateral at any such public sale; and the net proceeds of any
such public or private sale and all other amounts actually collected or
received by MLBFS pursuant hereto, after deducting all costs and expenses
incurred at any time in the collection of the Obligations and in the
protection, collection and sale of the Collateral, will be applied to the
payment of the Obligations, with any remaining proceeds paid to Customer or
whoever else may be entitled thereto, and with Customer and the Guarantors
remaining jointly and severally liable for any amount remaining unpaid after
such application.

(b)  REMEDIES ARE SEVERABLE AND CUMULATIVE.  All rights and remedies of MLBFS
herein are severable and cumulative and in addition to all other rights and
remedies available in the Note, the other Additional Agreements, at law or in
equity, and any one or more of such rights and remedies may be exercised
simultaneously or successively.

(c)  NOTICES.  To the fullest extent permitted by applicable law, Customer
hereby irrevocably waives and releases MLBFS of and from any and all
liabilities and penalties for failure of MLBFS to comply with any statutory or
other requirement imposed upon MLBFS relating to notices of sale, holding of
sale or reporting of any sale, and Customer waives all rights of redemption from
any such sale.  Any notices required under applicable law shall be reasonably
and properly given to Customer if given by any of the methods provided herein
at least 5 Business Days prior to taking action.  MLBFS shall have the right to
postpone or adjourn any sale or other disposition of Collateral at any time
without giving notice of any such postponed or adjourned date.  In the event
MLBFS seeks to take possession of any or all of the Collateral by court
process. Customer further irrevocably waives to the fullest extent permitted by
law any bonds and any surety or security relating thereto required by any
statute, court rule or otherwise as an incident to such possession, and any
demand for possession prior to the commencement of any suit or action.

4.7  MISCELLANEOUS.

(a)  NON-WAIVER.  No failure or delay on the part of MLBFS in exercising any
right, power or remedy pursuant to this Loan Agreement, the Term WCMA Note or
any of the other Additional Agreements shall operate as a waiver thereof, and no
single or partial exercise of any such right, power or remedy shall preclude any
other or further exercise thereof, or the exercise of any other right, power or
remedy.  Neither any amendment, modification, supplement, termination or waiver
of any provision of this Loan Agreement, the Term WCMA Note or any of the other
Additional Agreements, nor any consent to any departure by Customer therefrom,
shall be effective unless the same shall be in writing and signed by MLBFS.  Any
waiver of any provision of this Loan Agreement, the Term WCMA Note or any of the
other Additional Agreements and any consent to any departure by Customer from
the terms thereof shall be effective only in the specific instance and for the
specific purpose for which given.  Except as otherwise expressly provided
herein, no notice to or demand on Customer shall in any case entitle Customer to
any other or further notice or demand in similar or other circumstances.

(b)  SET-OFF; DISCLOSURE.  MLBFS shall have the right upon the occurrence and
during the continuance of an Event of Default to set-off, appropriate and apply
toward payment of any of the Obligations, in such order of application as MLBFS
may from time to time and at any time elect, any cash, credit, deposits,
accounts, securities and any other property of Customer which is in transit to
or in the possession, custody or control of MLBFS, MLPF&S or any agent, bailee,
or affiliate of MLBFS or MLPF&S including, without limitation, the WCMA Account
and any Money Accounts, and all cash and securities therein or controlled
thereby, and all proceeds thereof.  Customer hereby grants to MLBFS a security
interest in all such property as additional Collateral.  Customer and each
Guarantor hereby irrevocably authorized MLBFS and each of its affiliates,
including without limitation MLPF&S, to at any time (whether or not an Event of
Default shall have occurred) obtain from and disclose to each other any and all
financial and other information about Customer or any Guarantor.

(c)  COMMUNICATIONS.  All notices and other communications required or
permitted hereunder or in connection with any of the Additional Agreements
shall be in writing, and shall be either delivered personally, mailed by
postage prepaid certified mail or sent by express overnight courier or by
facsimile.  Such notices and communications shall be deemed to be given on the
date of personal delivery, facsimile



                                      -12-
<PAGE>   13
transmission or actual delivery of certified mail, or one Business Day after
delivery to an express overnight courier. Unless otherwise specified in a
notice sent or delivered in accordance with the terms hereof, notices and other
communications in writing shall be given to the parties hereto at their
respective addresses set forth at the beginning of this Loan Agreement, or, in
the case of facsimile transmission, to the parties at their respective regular
facsimile telephone number.

(d) COSTS, EXPENSES AND TAXES.  Customer shall upon demand pay or reimburse
MLBFS for: (i) all reasonable fees and out-of-pocket expenses of MLBFS
(including, but not limited to, reasonable fees and expenses of outside counsel
and Uniform Commercial Code filing and search fees and expenses) in connection
with the verification, protection, perfection or preservation of MLBFS' rights
hereunder or in the Collateral or any other collateral for the Obligations, or
the enforcement of this Loan Agreement or any of the Additional Agreements,
excluding, however, salaries and expenses of MLBFS' employees; and (ii) any and
all stamp, transfer and other taxes and fees payable or determined to be
payable in connection with the execution, delivery and/or recording of this
Loan Agreement or any of the Additional Agreements. If any suit or proceeding
arising from any of the foregoing is brought against MLBFS, Customer, to the
extent and in the manner directed by MLBFS, shall resist and defend such suit
or proceeding with counsel approved by MLBFS (such approval not to be
unreasonably withheld). The obligations of Customer under this paragraph shall
survive the expiration or termination of this Loan Agreement and the discharge
of the other Obligations.

(e) RIGHT TO PERFORM OBLIGATIONS.  If Customer shall fail to do any act or
thing which it has covenanted to do under this Loan Agreement or any
representation or warranty on the part of Customer contained in this Loan
Agreement shall be breached, MLBFS may, in its sole discretion, after 5
Business Days written notice is sent to Customer, do the same or cause it to be
done or remedy any such breach, and may expend its funds for such purpose.  Any
and all reasonable amounts so expended by MLBFS shall be repayable to MLBFS by
Customer upon demand, with interest at the Interest Rate during the period from
and including the date funds are so expended by MLBFS to the date of repayment,
and all such amounts shall be additional Obligations.

(f) LATE CHARGES.  Any payment required to be made by Customer pursuant to this
Loan Agreement or any of the Additional Agreements not paid within 5 Business
Days of the applicable due date shall be subject to a late charge in an amount
equal to the lesser of: (i) 5% of the overdue amount, or (ii) the maximum
amount permitted by applicable law.  Such late charges shall be payable on
demand, or, without demand, may in the sole discretion of MLBFS be paid by a
WCMA Loan and added to the WCMA Loan Balance in the same manner as provided
herein for accrued interest with respect to the WCMA Line of Credit.

(g) FURTHER ASSURANCES.  Customer agrees to do such further acts and things and
to execute and deliver to MLBFS such additional agreements, instruments and
documents as MLBFS may reasonably require or deem advisable to carry into
effect the purposes of this Loan Agreement, or to confirm unto MLBFS its
rights, powers and remedies under this Loan Agreement, the Term WCMA Note and
the other Additional Agreements.

(h) BINDING EFFECT.  This Loan Agreement, the Term WCMA Note and the other
Additional Agreements shall be binding upon, and shall inure to the benefit of
MLBFS, Customer and their respective successors and assigns.  Customer shall not
assign any of its rights or delegate any of its obligations under this Loan
Agreement, the Term WCMA Note or any of the other Additional Agreements without
the prior written consent of MLBFS. Unless otherwise expressly agreed to in a
writing signed by MLBFS, no such consent shall in any event relieve Customer of
any of its obligations under this Loan Agreement, the Term WCMA Note or any of
the other Additional Agreements.

(i) HEADINGS.  Captions and section and paragraph headings in this Loan
Agreement and the Additional Agreements are inserted only as a matter of
convenience, and shall not affect the interpretation hereof.

(j) GOVERNING LAW. This Loan Agreement, the Term WCMA Note and, unless otherwise
expressly provided therein, each of the other Additional Agreements, shall be

(m) INTEGRATION. THIS LOAN AGREEMENT, TOGETHER WITH THE TERM WCMA NOTE AND THE
OTHER ADDITIONAL AGREEMENTS, CONSTITUTES THE ENTIRE UNDERSTANDING AND REPRESENTS
THE FULL AND FINAL AGREEMENT BETWEEN THE PARTIES WITH RESPECT TO THE SUBJECT
MATTER HEREOF, AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR WRITTEN
AGREEMENTS OR PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE
PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS OF THE PARTIES.  WITHOUT
LIMITING THE FOREGOING, CUSTOMER ACKNOWLEDGES THAT: (i) NO PROMISE OR COMMITMENT
HAS BEEN MADE TO IT BY MLBFS, MLPF&S OR ANY OF THEIR RESPECTIVE EMPLOYEES,
AGENTS OR REPRESENTATIVES TO MAKE THE LOAN ON ANY TERMS OTHER THAN AS EXPRESSLY
SET FORTH HEREIN AND IN THE TERM WCMA NOTE, OR TO MAKE ANY OTHER LOAN OR
OTHERWISE EXTEND ANY OTHER CREDIT TO CUSTOMER OR ANY OTHER PARTY; AND (ii)

                               TERM WCMA(R) NOTE

FOR VALUE RECEIVED, ALANEX CORPORATION, a corporation organized and existing
under the laws of the State of California ("Customer"), hereby promises to pay
to the order of MERRILL LYNCH BUSINESS FINANCIAL SERVICES INC., a corporation
organized and existing under the laws of the State of Delaware ("MLBFS"), in
lawful money of the United States, the principal sum of $1,200,000.00, or, if
less, an amount equal to the sum of the balances from time to time outstanding
under the "Term Note" and "WCMA Note" included herein.

                                   TERM NOTE

FOR VALUE RECEIVED.  Customer hereby promises to pay to the order of MLBFS, in
lawful money of the United States, an amount equal to the difference between
(i) the principal sum of $1,200,000.00 or, if less, the aggregate amount
advanced by MLBFS to Customer pursuant to the "Loan Agreement," as herein
defined (the "Loan Amount"), and (ii) the sum of (x) the aggregate amount paid
by Customer on account of the principal hereof, and (y) the WCMA Line of Credit
(said difference being herein called the "Term Note Balance"); together with
interest on the Term Note Balance, from the date of advancement of funds
hereunder until payment, at the Interest Rate.

Said indebtedness shall be payable in 61 consecutive monthly installments
commencing on the first day of the calendar month following the calendar month
in which funds are advanced hereunder, and continuing on the first day of each
calendar month thereafter until this Note shall be paid in full.  The first such
installment shall be in an amount equal to accrued interest at the Interest Rate
and installments 2 through 61, both inclusive, shall be in an amount equal to
the sum of (i) accrued interest at the Interest Rate and (ii) 1/60th of the Loan
Amount.  Each payment received hereunder shall be applied first to interest at
the Interest Rate, with the balance applied on account of the Term Note Balance.
All sums payable hereunder shall be payable at the office of MLBFS at 33 West
Monroe Street, Chicago, Illinois 60603, or at such other place or places as the
holder hereof may from time to time appoint in writing.

Customer may prepay this Term Note at any time in whole or in part without
premium or penalty.  Any partial prepayment shall be applied to installments of
the Loan Amount in inverse order of maturity.  Customer shall not have the
right to re-borrow amounts prepaid on account of this Term Note.

                                   WCMA NOTE

FOR VALUE RECEIVED.  Customer hereby promises to pay to the order of MLBFS, at
the times and in the manner set forth in the Loan Agreement, or in such other
manner and at such place as MLBFS may hereafter designate in writing, the
following: (a) on the WCMA Maturity Date, the then WCMA Loan Balance; and (b)
interest at the Interest Rate on the outstanding WCMA Loan Balance, from and
including the date on which the initial WCMA Loan is made until the date of
payment of all WCMA Loans in full.  Interest shall be payable in the manner and
on the dates specified in, or determined in accordance with, the Loan Agreement.

             PROVISIONS APPLICABLE TO BOTH TERM NOTE AND WCMA NOTE

As used herein, the term "Interest Rate" shall mean a fluctuating per annum
rate equal to the sum of (i) 2.95%, and (ii) the interest rate from time to
time published in the "Money Rates" section of The Wall Street Journal for
30-day high-grade unsecured notes sold though dealers by major corporations
(the "30-Day

<PAGE>   2
Commercial Paper Rate").  The Interest Rate will change as of the date of
publication in The Wall Street Journal of a 30-Day Commercial Paper Rate that is
different from that published on the preceding Business Day.  In the event that
The Wall Street Journal shall, for any reason, fail or cease to publish the
30-Day Commercial Paper Rate, MLBFS will choose a reasonably comparable index or
source to use as the basis for the Interest Rate.  Any part of the principal
hereof or interest hereon not paid within 5 Business Days of the applicable due
date shall be subject to a late charge equal to the lesser of (i) 5% of the
overdue amount, or (ii) the maximum amount permitted by law.  All interest shall
be computed on the basis of actual days elapsed over a 360-day year.

This Term WCMA Note constitutes and includes both the "Term Note" and the "WCMA
Note" referred to in, and is entitled to all of the benefits of, that certain
Term WCMA Loan and Security Agreement No. 9406340101 between Customer and MLBFS
(the "Loan Agreement").  Capitalized terms used herein and not defined herein
shall have the meaning set forth in the Loan Agreement.  The Loan Agreement is
by this reference hereby incorporated as a part hereof.

If Customer shall fail to pay when due any installment or other sum due
hereunder, and any such failure shall continue for more than 5 Business Days
after written notice thereof from the holder hereof to Customer, or if any
other "Event of Default", as that term is defined in the Loan Agreement, shall
occur, then at the option of the holder hereof, and in addition to all other
rights and remedies available to such holder under the Loan Agreement and
otherwise, an amount equal to the sum of the WCMA Loan Balance and the Term
Note Balance at such time remaining unpaid, together with accrued interest
thereon, and all other sums then owing by Customer under the Loan Agreement,
may be declared to be and thereby become immediately due and payable.

It is expressly understood, however, that nothing contained in the Loan
Agreement, any other agreement, instrument or document executed by Customer, or
otherwise, shall affect or impair the right, which is unconditional and
absolute, of the holder hereof to enforce payment of all sums due under this
Term WCMA Note at or after maturity, whether by acceleration or otherwise, or
shall affect the obligation of Customer, which is also unconditional and
absolute, to pay the sums payable under this Term WCMA Note in accordance with
its terms.

Except as expressly otherwise provided herein or in the Loan Agreement,
Customer hereby waives presentment, demand for payment, protest and notice of
protest, notice of dishonor and all other notices and formalities in
connection with this Term WCMA Note.  Wherever possible each provision of this
Term WCMA Note shall be interpreted in such manner as to be effective and valid
under applicable law, but if any provision of this Term WCMA Note shall be
prohibited by or invalid under such law, such provision shall be ineffective to
the extent of such prohibition or invalidity without invalidating the remainder
of such provision or the remaining provisions of this Term WCMA Note.
Notwithstanding anything herein to the contrary, in no event shall any interest
charged hereunder exceed the highest rate permissible under any law which a
court of competent jurisdiction shall, in a final determination, deem
applicable hereto.  In the event that such a court determines that MLBFS has
received interest hereunder in excess of the highest rate applicable hereto,
MLBFS shall promptly refund such excess interest to Customer without charge or
penalty.  This Term WCMA Note shall be construed in accordance with the laws of
the State of Illinois and may be enforced by the holder hereof in any
jurisdiction in which the Loan Agreement may be enforced.


                                      -2-

FOR VALUE RECEIVED, and in order to induce MERRILL LYNCH BUSINESS FINANCIAL
SERVICES INC. ("MLBFS") to advance moneys or extend or continue to extend
credit to or for the benefit of ALANEX CORPORATION, a corporation organized and
existing under the laws of the State of California (with any successor-in
interest, including without limitation, any successor by merger or by operation
of law, herein collectively referred to as "Customer") under (a) that certain
Term WCMA Loan and Security Agreement No. 9406340101 between MLBFS and Customer
(the "Loan Agreement") and (b) any "Additional Agreements", as that term is
defined in the Loan Agreement (including, without limitation, the Term WCMA
Note incorporated by reference into the Loan Agreement (collectively, the
"Guaranteed Documents"), the undersigned AMGEN INC., a corporation duly
organized and validly existing under the laws of the State of Delaware
("Guarantor"), hereby unconditionally guarantees to MLBFS: (i) the prompt and
full payment when due, by acceleration or otherwise, of all sums now or any
time hereafter due from Customer to MLBFS under the Guaranteed Documents; and
(ii) the prompt, full and faithful performance and discharge by Customer of
each and every other covenant and warranty of Customer set forth in the
Guaranteed Documents (collectively, the "Obligations"). Guarantor further
agrees to pay all reasonable costs and expenses (including, but not limited to,
court costs and reasonable attorneys' fees) paid or incurred by MLBFS in
endeavoring to collect or enforce performance of any of the Obligations, or in
enforcing this Guaranty.

This Guaranty is absolute, unconditional and continuing and shall remain in
effect until all of the Obligations shall have been fully paid, performed and
discharged. Upon the occurrence and during the continuance of any Event of
Default under the Guaranteed Documents, any or all of the indebtedness hereby
guaranteed then existing shall, at the option of MLBFS, become immediately due
and payable from Guarantor. Notwithstanding the occurrence of any such event,
this Guaranty shall continue and remain in full force and effect until such
date as all of the Obligations have been fully paid, performed or discharged.
The liability of Guarantor hereunder shall in no event be affected or impaired
by any of the following, any of which may be done or omitted by MLBFS from time
to time, without notice to or the consent of Guarantor; (a) any renewals,
amendments, modifications or supplements of or to any of the Guaranteed
Documents, or any renewals, extensions, forbearances, compromises or releases
of any of the Obligations or any of MLBFS's rights under any of the Guaranteed
Documents; (b) any acceptance by MLBFS of any collateral or security for, or
other guarantors of, any of the Obligations; (c) any failure, neglect or
omission on the part of MLBFS to realize upon or protect any of the
Obligations, or any collateral or security therefor, or to exercise any lien
upon or right of appropriation of any moneys, credits or property of Customer
or any other guarantor, possessed by or under the control of MLBFS or any of
its affiliates, toward the liquidation or reduction of the Obligations; (d) any
application of payments or credits by MLBFS; (e) the granting of credit from
time to time by MLBFS to Customer in excess of the amount set forth in the
Guaranteed Documents [provided, however, that in no event will the granting of
any additional credit or any loan of additional moneys to Customer (beyond that
contemplated at the time the Guaranteed Documents are first signed by
Customer), under the Guaranteed Documents or otherwise, increase the liability
of Guarantor hereunder without its prior written consent]; or (f) any other act
of commission or omission of any kind or at any time upon the part of MLBFS or
any of its affiliates or any of their respective employees or agents with
respect to any matter whatsoever. MLBFS shall not be required at any time, as a
condition of Guarantor's obligations hereunder, to resort to payment from
Customer or other persons or entities whatsoever, or any of their properties or
estates, or resort to any collateral or pursue or exhaust any other rights or
remedies whatsoever.
No release or discharge in whole or in part of any other guarantor of the
Obligations shall release or discharge Guarantor unless and until all of the
Obligations shall have been fully paid and discharged. Guarantor expressly
waives presentment, protest, demand, notice of dishonor or default, notice of
<PAGE>   8
acceptance of this Guaranty, notice of advancement of funds under the
Guaranteed Documents and all other notices and formalities to which Customer or
Guarantor might be entitled, by statute or otherwise.

Guarantor further waives any claim, right or remedy which Guarantor may now
have or hereafter acquire against Customer that arises hereunder and/or from
the performance by Guarantor hereunder, including, without limitation, any
claim, remedy or right of subrogation, reimbursement, exoneration,
contribution, indemnification, or participation in any claim, right or remedy
of MLBFS against Customer or any security which MLBFS now has or hereafter
acquires, whether or not such claim, right or remedy arises in equity, under
contract, by statute, under common law, or otherwise.

Guarantor further hereby irrevocably authorizes MLBFS and each of its
affiliates, including without limitation MLPF&S, to at any time (whether or not
an Event of Default shall have occurred) obtain from and disclose to each other
any and all financial and other information about Guarantor.

No delay on the part of MLBFS in the exercise of any right or remedy under any
agreement (including, but not limited to, this Guaranty) shall operate as a
waiver thereof, and, without limiting the foregoing, no delay in the
enforcement of any security interest, and no single or partial exercise by
MLBFS of any right or remedy shall preclude any other or further exercise
thereof or the exercise of any other right or remedy.  This Guaranty may be
executed in any number of counterparts, each of which counterparts, once they
are executed and delivered, shall be deemed to be an original and all of which
counterparts, taken together, shall constitute but one and the same Guaranty.
This Guaranty shall be binding upon Guarantor and its successors and assigns,
and shall inure to the benefit of MLBFS and its successors and assigns. If
there is more than one guarantor of the Obligations, all of the obligations and
agreements of Guarantor are joint and several with such other guarantors.

This Guaranty shall be governed by the laws of the State of Illinois.
GUARANTOR AGREES THAT THIS GUARANTY MAY BE ENFORCED BY MLBFS IN ANY
JURISDICTION AND VENUE IN WHICH THE LOAN AGREEMENT MAY BE ENFORCED.  GUARANTOR
AND MLBFS HEREBY EACH EXPRESSLY WAIVE ANY AND ALL RIGHTS TO A TRIAL BY JURY IN
ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER OF THE PARTIES AGAINST
THE OTHER PARTY IN ANY WAY RELATED TO OR ARISING OUT OF THIS GUARANTY OR THE
OBLIGATIONS.  Wherever possible each provision of this Guaranty shall be
interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Guaranty shall be prohibited by or invalid under
such law, such provision shall be ineffective only to the extent of such
prohibition or invalidity, without invalidating the remainder of such provision
or the remaining provisions of this Guaranty.  No modification or wavier of any
of the provisions of this Guaranty shall be effective unless in writing and
signed by both Guarantor and an officer of MLBFS.

          (ii) Any other service to be provided by Lessor that is elsewhere in
this Lease stated to be an "Operating Expense." 

          (iii) The cost of water/sewer, gas and electricity as stipulated in 
Exhibit E. 
  
      (c) The inclusion of the improvements, facilities and services set 
forth in paragraph 4.2(b)(f)(i) of the definition of Operating Expenses shall 
not be deemed to impose an obligation upon Lessor to either have said 
improvements of facilities or to provide those services unless the Industrial 
Center already has the same, Lessor already provides the services or Lessor 
has agreed elsewhere in this Lease to provide the same or some of them. 
(d) Lessee's Share of Operating Expense shall be payable by Lessee within
ten (10) days after a reasonably detailed statement of actual expenses is
presented to Lessee by Lessor.

5.  SECURITY DEPOSIT. Lessee shall deposit with Lessor upon execution hereof 
$      Refer to Exhibit E as security for Lessee's faithful performance of 
Lessee's obligations hereunder.  If Lessee fails to pay rent or other charges
due hereunder, or otherwise defaults with respect to any provision of this
Lease, Lessor may use, apply or retain all or any portion of said deposit for
the payment of any rent or other charge in default or for the payment of any
other sum to which Lessor may become obligated by reason of Lessee's default, or
to compensate Lessor for any loss or damage which Lessor may suffer thereby.  If
Lessor so uses or applies all or any portion of said deposit, Lessee shall
within ten (10) days after written demand therefor deposit cash with Lessor in
an amount sufficient to restore said deposit to the full amount then required of
Lessee.  If the monthly rent shall, from time to time, increase during the term
of this Lease, Lessee shall, at the time of such increase, deposit with Lessor
additional money as a security deposit so that the total amount of the security
deposit held by Lessor shall at all times bear the same proportion to the then
current Base Rent as the initial security deposit bears to the initial Base Rent
set forth in paragraph 4.  Lessor shall not be required to keep said security
deposit separate from its general accounts.  If Lessee performs all of Lessee's
obligations hereunder, said deposit, or so much thereof as has not theretofore
been applied by Lessor, shall be returned, without payment of interest or other
increment for its use, to Lessee (or at Lessor's option, to the last assignee,
if any, of Lessee's interest hereunder) at the expiration of the term hereof,
and after Lessee has vacated the Premises.  No trust relationship is created
herein between Lessor and Lessee with respect to said Security Deposit.   Refer
to Exhibit E, Security Deposit

6.  USE
        6.1  USE.  The Premises shall be used and occupied only for office and
science laboratory in accordance with City of San Diego scientific research 
zoning or any other use which is reasonably comparable and for no other 
purpose.

        6.2     COMPLIANCE WITH LAWS
               
                 (a) Lessor warrants to Lessee that the Premises, in the state
existing on the date that the Lease term commences, but without regard to the
use for which Lessee will occupy the Premises, does not violate any covenants
or restrictions of record, or any applicable building code, regulation or
ordinance in effect on such Lease term commencement date.  In the event it is
determined that this warranty has been violated, then it shall be the
obligation of the Lessor, after written notice from Lessee, to promptly, at
Lessor's sole cost and expense, rectify any such violation.  In the event
Lessee does not give to Lessor written notice of the violation of this warranty
within six months from the date that the Lease term commences, the correction
of same shall be the obligation of the Lessee at Lessor's sole cost. The
warranty contained in this paragraph 6.2(a) shall be of no force or effect if,
prior to the date of this Lease, Lessee was an owner or occupant of the
Premises and, in such event, Lessor shall correct any such violation at
Lessee's sole cost.  Refer to Paragraphs 48 and 49.

                (b) Except as provided in paragraph 6.2(a) Lessee shall, at
Lessee's expense, promptly comply with all applicable statutes, ordinances,
rules, regulations, orders, covenants and restrictions of record, and
requirements of any fire insurance underwriters or rating bureaus, now in effect
or which may hereafter come into effect, whether or not they reflect a change in
policy from that now existing, during the term or any part of the term hereof,
relating in any manner to the Premises and the occupation and use by Lessee of
the Premises and of the Common Areas.  Lessee shall not use nor permit the use 
of the Premises of the Common Areas in any manner that will tend to create 
waste or a nuisance or shall tend to disturb other occupants of the Industrial 
Center.  Refer to Paragraph 50.

        6.3     CONDITION OF PREMISES.

                (a) Lessor shall deliver the Premise to Lessee clean and free of
debris on the Lease commencement date (unless Lessee is already in possession)
and Lessor warrants to Lessee that the plumbing, lighting, air conditioning,
heating, and loading doors in the Premises shall be in good operating condition
on the Lease commencement date.  In the event that it is determined that this
warranty has been violated, then it shall be the obligation of Lessor, after
receipt of written notice from Lessee setting forth with specificity the nature
of violation, to promptly, at Lessor's sole cost, rectify such violation.
Lessee's failure to give such written notice to Lessor within thirty (30) days
after the Lease commencement date shall cause the conclusive presumption that
Lessor has complied with all of Lessor's obligations hereunder.  The warranty
contained in this paragraph 6.3(a) shall be of no force or effect if prior to
the date of this Lease, Lessee was an owner or occupant of the Premises.

                (b) Except as otherwise provided in this Lease, Lessee hereby
accepts the Premises in their condition existing as of the Lease commencement
date or the date that Lessee takes possession of the Premises, whichever is
earlier, subject to all applicable zoning, municipal, county and state laws,
ordinances and regulations governing and regulating the use of the Premises,
and any covenants or restrictions of record, and accepts this Lease subject
thereto and to all matters disclosed thereby and by any exhibits attached
hereto. Lessee acknowledges that neither Lessor not Lessor's agent has made
any representation or warranty as to the present or future suitability of the
Premises for the conduct of Lessee's business. Refer to Paragraph 51

7.      MAINTENANCE, REPAIRS, ALTERATIONS AND COMMON AREA SERVICES.

        7.1  LESSOR'S OBLIGATIONS.  Subject to the provisions of paragraphs 4.2
(Operating Expenses), 6(Use), 7.2 (Lessee's Obligations) and 9 (Damage or
Destruction) and except for damage caused by any negligent or intentional act
or omission or Lessee, Lessee's employees, suppliers, shippers, customers, or
invitees, in which event Lessee shall repair the damage.  Lessor, at Lessor's
expense, subject to reimbursement pursuant to paragraph 4.2, shall keep in good
condition and repair the foundations, exterior walls, structural condition of
interior bearing walls, and roof of the Premises, as well as the parking lots,
walkways, driveways, landscaping, fences, signs and utility installations of
the Common Areas and all parts thereof, as well as providing the services for
which there is an Operating Expense pursuant to paragraph 4.2. Lessor shall not,
however, be obligated to paint the exterior or interior surface of exterior
walls, nor shall Lessor be required to maintain, repair or replace windows,
doors or plate glass of the Premises.  Lessor shall have no obligation to make
repairs under this paragraph 7.1 until a reasonable time after receipt of
written notice from Lessee of the need for such repairs.  Lessee expressly
waives the benefits of any statute now or hereafter in effect which would
otherwise afford Lessee the right to make repairs at Lessor's expense or to
terminate this Lease because of Lessor's failure to keep the Premises in good
order, condition and repair.  Lessor shall not be liable for damages or loss of
any kind or nature by reason of Lessor's failure to furnish any Common Area
Services when such failure is caused by accident, breakage, repairs, strikes,
lockout, or other labor disturbances or disputes of any character, or by any
other cause beyond the reasonable control of Lessor.

        7.2     LESSEE'S OBLIGATIONS.

                (a) Subject to the provisions of paragraphs 6 (Use), 7.1
(Lessor's Obligations), and 9 (Damage or Destruction), Lessee at Lessee's
expense, shall keep in good order, condition and repair the Premises and every
part thereof (whether or not the damaged portion of the Premises or the means
of repairing the same are reasonably or readily accessible to Lessee)
including, without limiting the generality of the foregoing, all plumbing,
heating, ventilating and air conditioning systems (Lessee shall procure and
maintain, at Lessee's expense, a ventilating and air conditioning system
maintenance contract), electrical and lighting facilities and equipment within
the Premises, fixtures, interior walls and interior surfaces of exterior walls,
ceilings, windows, doors, plate glass, and skylights located within the
Premises.  Lessor reserves the right to procure and maintain the ventilating
and air conditioning system maintenance contract and if Lessor so elects, Lessee
shall reimburse Lessor, upon demand, for the cost thereof. Refer to
Paragraph 52

                (b) If Lessee fails to perform Lessee's obligations under this
paragraph 7.2 or under any other paragraph of this lease, Lessor may enter upon
the Premises after ten (10) days' prior written notice to Lessee (except in the
case of emergency, in which no notice shall be required), perform such
obligations on Lessee's behalf and put the Premises in good order, condition
and repair, and the cost thereof together with interest thereon at the maximum
rate then allowable by law shall be due and payable as additional rent to
Lessor together with Lessee's next Base Rent installment.

                (c) On the last day of the term hereof, or on any sooner
termination, Lessee shall surrender the Premises to Lessor in the same
condition as received, ordinary wear and tear excepted, clean and free of
debris.  Any damage or deterioration of the Premises shall not be deemed
ordinary wear and tear if the same could have been prevented by good
maintenance practices.  Lessee shall repair any damage to the Premises
occasioned by the installation or removal of Lessee's trade fixtures,
alterations, furnishings and equipment.  Notwithstanding anything to the
contrary otherwise stated in this Lease, Lessee shall leave the air lines,
power panels, electrical distribution systems, lighting fixtures, space
heaters, air conditioning, plumbing and fencing on the Premises in good
operating condition.  Refer to Paragraph 53

        7.3     ALTERATIONS AND ADDITIONS.

                (a)  Lessee shall not, without Lessor's prior written consent
make any alterations, improvements, additions, or Utility installations in, on
or about the Premises, or the Industrial Center, except for nonstructual
alterations to the Premises not exceeding $2,500 in cumulative costs, during
the term of this Lease. In any event, whether or not in excess of $2,500 in
cumulative cost, Lessee shall make no change or alteration to the exterior 
of the Premises nor the exterior of the Building nor the Industrial Center 
without Lessor's prior written consent.  As used in this paragraph 7.3 the 
term "Utility Installation" shall mean carpeting, window coverings, air 
lines, power panels, electrical distribution systems, lighting fixtures, 
space heaters, air conditioning, plumbing, ducting, Hoods and fencing.  
Lessor may require that Lessee remove any or all of said alterations, 
improvements, additions or Utility installations at the

expiration of the term, and restore the Premises and the Industrial Center to
their existing condition on the date of possession, Lessor may require Lessee
to provide Lessor, at Lessee's sole cost and expense, a lien and completion
bond in an amount equal to one and one-half times the estimated cost of such
improvements, to insure Lessor against any liability for mechanic's and
materialmen's liens and to insure completion of the work.  Should Lessee make
any alterations, improvements, additions or Utility Installations without the
prior approval of Lessor, Lessor may, at any time during the term of the Lease,
require that Lessee remove any or all of the same.  Refer to Paragraph 54.

        (b)  Any alterations, improvements, additions or Utility Installations
in or about the Premises or the Industrial Center that Lessee shall desire to
make and which requires the consent of the Lessor shall be presented to Lessor
in written form, with proposed detailed plans.  If Lessor shall give its
consent, the consent shall be deemed conditioned upon Lessee acquiring a permit
to do so from appropriate governmental agencies, the furnishing of a copy
thereof to Lessor prior to the commencement of the work and the compliance by
Lessee of all conditions of said permit in a prompt and expeditious manner.
Lessor's consent shall not be unreasonably withheld.

        (c)  Lessee shall pay, when due, all claims for labor or materials
furnished or alleged to have been furnished to or for Lessee at or for use in
the Premises, which claims are or may be secured by any mechanic's or
materialmen's lien against the Premises, or the Industrial Center, or any
interest therein. Lessee shall give Lessor not less than ten (10) days' notice
prior to the commencement of any work in the Premises, and Lessor shall have the
right to post notices of non-responsibility in or on the Premises or the
Building as provided by law.  If Lessee shall, in good faith, contest the
validity of any such lien, claim or demand, then Lessee shall, at its sole
expense defend itself and Lessor against the same and shall pay and satisfy any
such adverse judgment that may be rendered thereon before the enforcement
thereof against the Lessor or the Premises or the Industrial Center, upon the
condition that if Lessor shall require, Lessee shall furnish to Lessor a surety
bond satisfactory to Lessor in an amount equal to such contested lien claim or
demand indemnifying Lessor against liability for the same and holding the
Premises and the Industrial Center free from the effect of such lien or claim.
In addition, Lessor may require Lessee to pay Lessor's attorney's fees and costs
in participating in such action if Lessor shall decide it is to Lessor's best
interest to do so.

          (d)  All alterations, improvements, additions and Utility
Installations which may be made on the Premises shall be the property of Lessor
and shall remain upon and be surrendered with the Premises at the expiration of
the Lease term, unless Lessor requires their removal pursuant to paragraph
7.3(a). Notwithstanding the provisions of this paragraph 7.3(d), Lessee's
machinery and equipment, other than that which is affixed to the Premises so
that it cannot be removed without material damage to the Premises, and other
than Utility Installations, shall remain the property of Lessee and may be
removed by Lessee subject to the provisions of paragraph 7.2.

     7.4  UTILITY ADDITIONS.  Lessor reserves the right to install new or
additional utility facilities throughout the Building and the Common Areas for
the benefit of Lessor or Lessee, or any other lessee of the Industrial Center,
including, but not by way of limitation, such utilities as plumbing, electrical
systems, security systems, communication systems, and fire protection and
detection systems, so long as such installations do not unreasonably interfere
with Lessee's use of the Premises.

8.  INSURANCE; INDEMNITY.

     8.1  LIABILITY INSURANCE--LESSEE.  Lessee shall, at Lessee's expense,
obtain and keep in force during the term of this Lease a policy of Combined
Single Limit Bodily Injury and Property Damage Insurance insuring Lessee and
Lessor against any liability arising out of the use, occupancy or maintenance of
the Premises and the Industrial Center.  Such insurance shall be in an amount
not less than $1,000,000 per occurrence.  The policy shall insure performance by
Lessee of the indemnity provisions of this paragraph 8.  The limits of said
Insurance shall not, however, limit the liability of Lessee hereunder.

     8.2  LIABILITY INSURANCE--LESSOR.  Lessor shall obtain and keep in force
during the term of this Lease a policy of Combined Single Limit Bodily Injury
and Property Damage Insurance, insuring Lessor, but not Lessee, against any
liability arising out of the ownership, use, occupancy or maintenance of the
Industrial Center in an amount not less than $1,000,000 per occurrence.

     8.3  PROPERTY INSURANCE.  Lessor shall obtain and keep in force during the
term of this Lease a policy or policies of insurance covering loss or damage to
the premises, but not Lessee's personal property, fixtures, equipment or tenant
improvements, in an amount not to exceed the full replacement value thereof, as
the same may exist from time to time, providing protection against all
perils included within the classification of fire, extended coverage, vandalism,
malicious mischief, flood (in the event same is required by a lender having a
lien on the Premises), special extended perils ("all risk," as such term is used
in the insurance industry), plate glass insurance and such other insurance as
Lessor deems advisable.  In addition, Lessor shall obtain and keep in force,
during the term of this Lease, a policy of rental value insurance covering a
period of one year, with loss payable to Lessor, which insurance shall also
cover all Operating Expenses for said period.

     8.4    DELETED Refer to Paragraph 55.

     8.5  INSURANCE POLICIES.  Insurance required hereunder shall be in
companies holding a "General Policyholders Rating" of at least 8 plus, or such
other rating as may be required by a lender having a lien on the Premises, as
set forth in the most current issue of "Best's Insurance Guide".  Lessee shall
not do or permit to be done anything which shall invalidate the insurance
policies carried by Lessor.  Lessee shall deliver to Lessor copies of liability
insurance policies required under paragraph 8.1 or certificates evidencing the
existence and amounts of such insurance within seven (7) days after the
commencement date of this Lease.  No such policy shall be cancellable or subject
to reduction of coverage or other modification except after thirty (30) days
prior written notice to Lessor.  Lessee shall, at least thirty (30) days prior
to the expiration of such policies, furnish Lessor with renewals or "binders"
thereof.  Lessee's insurance policies shall name Lessor as additional insured.

     8.6  WAIVER OF SUBROGATION.  Lessee and Lessor each hereby release and
relieve the other, and waive their entire right of recovery against the other
for loss or damage arising out of or incident to the perils insured against
which perils occur in, on or about the Premises, whether due to the negligence
of Lessor or Lessee or their agents, employees, contractors and/or invitees.
Lessee and Lessor shall, upon obtaining the policies of insurance required
hereunder, give notice to the insurance carrier or carriers that the foregoing
mutual waiver of subrogation is contained in this Lease.

     8.7  INDEMNITY.  Lessee shall indemnify and hold harmless Lessor from and
against any and all claims arising from Lessee's use of the Industrial Center,
or from the conduct of Lessee's business or from any activity, work or things
done, permitted or suffered by Lessee in or about the Premises or elsewhere and
shall further indemnify and hold harmless Lessor from and against any and all
claims arising from any breach or default in the performance of any obligation
on Lessee's part to be performed under the terms of this Lease, or arising from
any act or omission of Lessee, or any of Lessee's agents, contractors, or
employees, and from and against all costs, attorney's fees, expenses and
liabilities incurred in the defense of any such claim or any action or
proceeding brought thereon, and in case any action or proceeding be brought
against Lessor by reason of any such claim. Lessee upon notice from Lessor
shall defend the same at Lessee's expense by counsel reasonably satisfactory to
Lessor and Lessor shall cooperate with Lessee in such defense.  Lessee, as a
material part of the consideration to Lessor, hereby assumes all risk of damage
to property of Lessee or injury to persons, in, upon or about the Industrial
Center arising from any cause and Lessee hereby waives all claims in respect
thereof against Lessor.  Refer to Paragraph 56(a).

     8.8  EXEMPTION OF LESSOR FROM LIABILITY. Lessee hereby agrees that Lessor
shall not be liable for injury to Lessee's business or any loss of income
therefrom or for damage to the goods, wares, merchandise or other property of
Lessee, Lessee's employees, invitees, customers, or any other person in or
about the Premises or the Industrial Center, nor shall Lessor be liable for
injury to the person of Lessee, Lessee's employees, agents or contractors,
whether such damage or injury is caused by or results from fire, steam,
electricity, gas, water or rain, or from the breakage, leakage, obstruction or
other defects of pipes, sprinklers, wires, appliances, plumbing, air
conditioning or lighting fixtures, or from any other cause, whether said damage
or injury results from conditions arising upon the Premises or upon other
portions of the Industrial Center, or from other sources or places and
regardless of whether the cause of such damage or injury or the means of
repairing the same is inaccessible to Lessee, Lessor shall not be liable for
any damages arising from any act or neglect of any other lessee, occupant or
user of the Industrial Center, nor from the failure of Lessor to enforce the
provisions of any other lease of the Industrial Center. Refer to Paragraph
56(b).

9.4 and 9.5, if at any time during the term of this lease there is damage
which is an Insured Loss and which falls into the classification of either

case this Lesse shall be cancelled and terminated as of the date of the

of the date of occurrence of such damage by giving written notice to Lessee of
Lessor's election to do so within 30 days after the date of occurrence of such
damage.

                (b)     Notwithstanding paragraph 9.4(a), in the event that
Lessee has an option to extend or renew this Lease, and the time within which
said option may be exercised has not yet expired, Lessee shall exercise such
option, if it is to be exercised at all, no later than twenty (20) days after 
the occurrence of an Insured Loss falling within the classification of Premises
Partial Damage, during the last six months of the term of this Lease.  If
Lessee duly exercises such option during said twenty (20) day period, Lessor
shall, at Lessor's expense, repair such damage, but not Lessee's fixtures,
equipment or tenant improvements, as soon as reasonably possible and this
Lease shall continue in full force and effect.  If Lessee fails to exercise such
option during said twenty (20) day period, then Lessor may at Lessor's option
terminate and cancel this Lease as of the expiration of said twenty (20) day
period by giving written notice to Lessee of Lessor's election to do so within
ten (10) days after the expiration of said twenty (20) day period,
notwithstanding any term or provision in the grant of option to the contrary.

        9.5     ABATEMENT OF RENT; LESSEE'S REMEDIES.

                (a)     In the event Lessor repairs or restores the Premises
pursuant to the provisions of this paragraph 9, the rent payable hereunder for
the period during which such damage, repair or restoration continues shall be
abated in proportion to the degree to which Lessee's use of the Premises is
impaired.  Except for abatement of rent, if any, Lessee shall have no claim
against Lessor for any damage suffered by reason of any such damage,
destruction, repair or restoration.

                (b)     If Lessor shall be obligated to repair or restore the
Premises under the provisions of this paragraph 9 and shall not commence such
repair or restoration within ninety (90) days after such obligation shall
accrue, Lessee may at Lessee's option cancel and terminate this Lease by giving
Lessor written notice of Lessee's election to do so at any time prior to the
commencement of such repair or restoration.  In such event this Lease shall
terminate as of the date of such notice.

        9.6     TERMINATION -- ADVANCE PAYMENTS.  Upon termination of this Lease
pursuant to this paragraph 9, an equitable adjustment shall be made concerning
advance rent and any advance payments made by Lessee to Lessor.  Lessor shall,
in addition, return to Lessee so much of Lessee's security deposit as has not
theretofore been applied by Lessor.

        9.7     WAIVER.  Lessor and Lessee waive the provisions of any statute
which relate to termination of leases when leased property is destroyed and 
agree that such event shall be governed by the terms of this Lease.

10.     REAL PROPERTY TAXES.

        10.1    PAYMENT OF TAX INCREASE.  Lessee shall pay in addition to rent
the prorata share of the real property tax, as defined in paragraph 10.3,
applicable to the Industrial Center, provided, however, that Lessee shall
pay, in addition to rent, Lessee's Share (as defined in paragraph 4.2(a)) of 
the amount, if any, by which real property taxes applicable to the Premises
increase over the fiscal real estate tax year 1993 - 1994.  Such payment shall
be made by Lessee within ten (10) days after receipt of Lessor's written
statement setting forth the amount of such increase and the computation 
thereof.  If the term of this Lease shall not expire concurrently with the 
expiration of the tax fiscal year, Lessee's liability for increased taxes for 
the last partial lease year shall be prorated on an annual basis.  Refer 
to Paragraph 57

        10.2    ADDITIONAL IMPROVEMENTS.  Lessee shall not be responsible for
paying Lessee's Share of any increase in real property tax specified in the tax
assessor's records and work sheets as being caused by additional improvements
placed upon the Industrial Center by other lessees or by Lessor for the
exclusive enjoyment of such other lessees.  Lessee shall, however, pay to
Lessor at the time that Operating Expenses are payable under paragraph 4.2(c)
the entirety of any increase in real property tax if assessed solely by reason
of additional improvements placed upon the Premises by Lessee or at Lessee's 
request.

        10.3    DEFINITION OF "REAL PROPERTY TAX."  As used herein, the term
"real property tax" shall include any form of real estate tax or assessment,
general, special, ordinary or extraordinary, and any license fees, commercial
rental tax, improvement bond or bonds, levy or tax (other than inheritance,
personal income or estate taxes) imposed on the Industrial Center or any
portion thereof by any authority having the direct or indirect power to tax,
including any city, county, state or federal government, or any school,
agricultural, sanitary, fire, street, drainage or other improvement district
thereof, as against any legal or equitable interest of Lessor in the Industrial
Center or in any portion thereof, as against Lessor's right to rent or other
income therefrom, and as against Lessor's business of leasing Industrial
Center.  The term "real property tax" shall also include any tax, fee, levy,
assessment or charge (i) in substitution of, partially or totally, any tax,
fee, levy, assessment or charge hereinabove included within the definition of
"real property tax," or (ii) the nature of which was hereinbefore included
within the definition of "real property tax," or (ii) which is imposed for a
service or right not charged prior to June 1, 1978, or, if previously charged,
has been increased since June 1, 1978.

        10.5    PERSONAL PROPERTY TAXES.
                
                (a)     Lessee shall pay prior to delinquency as taxes assessed
against and levied upon trade fixtures, furnishings, equipment and all other
personal property of Lessee contained in the Premises or elsewhere.  Lessee
shall cause said trade fixtures, furnishings, equipment and all other personal
property to be assessed and billed separately from the real property of Lessor.

                (b)     If any of Lessee's said personal property shall be
assessed with Lessor's real property, Lessee shall pay to Lessor the taxes
attributable to Lessee within ten (10) days after receipt of a written statement
setting forth the taxes applicable to Lessee's property.

11.     UTILITIES.      Except as covered in Paragraph 58, Lessor, shall pay for
all water, gas, heat, light, power and other utilities and services supplied to
the Premises, together with any taxes thereon.  If any such services are not
separately metered to the Premises, Lessee shall pay at Lessor's option, either
Lessee's Share or a reasonable proportion to be determined by Lessor of all
charges jointly metered with other premises in the Building.  Refer to Paragraph
58.

12.     ASSIGNMENT AND SUBLETTING.

        12.1    LESSOR'S CONSENT REQUIRED.  Lessee shall not voluntarily or by
operation of law assign, transfer, mortgage, sublet, or otherwise transfer or
encumber all or any part of Lessee's interest in the Lease or in the Premises, 
without Lessor's prior written consent, which Lessor shall not unreasonably
withhold.  Lessor shall respond to Lessee's request for consent hereunder in a
timely manner and any attempted assignment, transfer, mortgage, encumbrance or
subletting without such consent shall be void, and shall constitute a breach of
this Lease without the need for notice to Lessee under paragraph 13.1.

        12.2    LESSEE AFFILIATE.  Notwithstanding the provisions of paragraph
12.1 hereof, Lessee may assign or sublet the Premises, or any portion thereof,
without Lessor's consent, to any corporation which controls, is controlled by or
is under common control with Lessee, or to any corporation resulting from the
merger or consolidation with Lessee, or to any person or entity which acquires
all the assets of Lessee as a going concern of the business that is being
conducted on the Premises, all of which are referred to as "Lessee Affiliate,"
provided that before such assignment shall be effective said assignee shall
assume, in full, the obligations of Lessee under this Lease.  Any such
assignment shall not, in any way, affect or limit the liability of Lessee under
the terms of this Lease even if after such assignment or subletting the terms
of this Lease are materially changed or altered without the consent of Lessee,
the consent of whom shall not be necessary.

        12.3    TERMS AND CONDITIONS OF ASSIGNMENT.  Regardless of Lessor's
consent, no assignment shall release Lessee of Lessee's obligations hereunder
or alter the primary liability of Lessee to pay the Base Rent and Lessee's Share
of Operating Expenses, and to perform all other obligations to be performed by
Lessee hereunder.  Lessor may accept rent from any person other than Lessee
pending approval or disapproval of such assignment.  Neither a delay in the
approval or disapproval of such assignment nor the acceptance of rent shall
constitute a waiver or estoppel of Lessor's right to exercise its remedies for
the breach of any of the terms or conditions of this paragraph 12 or this
Lease.  Consent to one assignment shall not be deemed consent to any subsequent
assignment.  In the event of default by any assignee of Lessee or any successor
of Lessee, in the performance of any of the terms hereof, Lessor may proceed
directly against Lessee without the necessity of exhausting remedies against
said assignee.  Lessor may consent to subsequent assignments of this Lease or
amendments or modifications to this Lease with assignees of Lessee, without
notifying Lessee, or any successor of Lessee, and without obtaining its or their
consent thereto and such action shall not relieve Lessee of liability under this
Lease.

        12.4    TERMS AND CONDITIONS APPLICABLE TO SUBLETTING.  Regardless of
Lessor's consent, the following terms and conditions shall apply to any
subletting by Lessee of all or any part of the Premises and shall be included in
subleases:

                (a)  Lessee hereby assigns and transfers to Lessor all of
Lessee's interest in all rentals and income arising from any sublease
heretofore or hereafter made by Lessee, and Lessor may collect such rent and
income and apply same toward Lessee's obligations under this Lease; provided,
however, that until a default shall occur in the performance of Lessee's
obligations under this Lease, Lessee may receive, collect and enjoy the rents
accruing under such sublease.  Lessor shall not, by reason of this or any other
assignment of such sublease to Lessor nor by reason of the collection of the
rents from a sublessee, be deemed liable to the sublessee for any failure of
Lessee to perform and comply with any of Lessee's obligations to such sublessee
under such sublease.  Lessee hereby irrevocably authorizes and directs any such
sublessee, upon receipt of a written notice from Lessor stating that a default
exists in the performance of Lessee's obligations under this Lease, to pay to
Lessor the rents due and to become due under the sublease.  Lessee agrees that
such sublessee shall have the right to rely upon any such statement and request
from Lessor, and that such sublessee shall pay such rents to Lessor without any
obligation or right to inquire as to whether such default exists and
notwithstanding any notice from or claim from Lessee to the contrary.  Lessee
shall have no right or claim against such sublessee or Lessor for any such
rents so paid by said sublessee to Lessor.

                (b) No sublease entered into by Lessee shall be effective
unless and until it has been approved in writing by Lessor.  In entering into
any sublease, Lessee shall use only such form of sublease as is satisfactory to
Lessor, and once approved by Lessor, such sublease shall not be changed or
modified without Lessor's prior written consent.  Any sublessee shall, by
reason of entering into a sublease under this Lease, be deemed, for the benefit
of Lessor, to have assumed and agreed to conform and comply with each and every
obligation herein to be performed by Lessee other than such obligations as are
contrary to or inconsistent with provisions contained in a sublease to which
Lessor has expressly consented in writing.

                (c) If Lessee's obligations under this Lease have been
guaranteed by third parties, then a sublease, and Lessor's consent thereto,
shall not be effective unless said guarantors give their written consent to
such sublease and the terms thereof.

                (d) The consent by Lessor to any subletting shall not release
Lessee from its obligations or alter the primary liability of Lessee to pay the
rent and perform and comply with all of the obligations of Lessee to be
performed under this Lease.

                (e) The consent by Lessor to any subletting shall not
constitute a consent to any subsequent subletting by Lessee or to any assignment
or subletting by the sublessee.  However, Lessor may consent to subsequent
sublettings and assignments of the sublease or any amendments or modifications
thereto without notifying Lessee or anyone else liable on the Lease or sublease
and without obtaining their consent and such action shall not relieve such
persons from liability.

                (f) In the event of any default under this Lease, Lessor may
proceed directly against Lessee, any guarantors or any one else responsible for
the performance of this Lease, including the sublessee, without first
exhausting Lessor's remedies against any other person or entity responsible
therefor to Lessor, or any security held by Lessor or Lessee.

                (g) In the event Lessee shall default in the performance of its
obligations under this Lease, Lessor, at its option and without any obligation
to do so, may require any sublessee to attorn to Lessor, in which event Lessor
shall undertake the obligations of Lessee under such sublease from the time of
the exercise of said option to the termination of such sublease; provided,
however, Lessor shall not be liable for any prepaid rents or security deposit
paid by such sublessee to Lessee or for any other prior defaults of Lessee
under such sublease.

                (h) Each and every consent required of Lessee under a sublease
shall also require the consent of Lessor.

                (i) No sublessee shall further assign or sublet all or any part
of the Premises without Lessor's prior written consent.

                (j) Lessor's written consent to any subletting of the Premises
by Lessee shall not constitute an acknowledgement that no default then exists
under this Lease of the obligations to be performed by Lessee nor shall such
consent be deemed a waiver of any then existing default, except as may be
otherwise stated by Lessor at the time.

                (k) With respect to any subletting to which Lessor has
consented, Lessor agrees to deliver a copy of any notice of default by Lessee
to the sublessee.  Such sublessee shall have the right to cure a default of
Lessee within ten (10) days after service of said notice of default upon such
sublessee, and the sublessee shall have a right of reimbursement and offset
from and against Lessee for any such defaults cured by the sublessee.

        12.5    ATTORNEY'S FEES.  In the event Lessee shall assign or sublet the
Premises or request the consent of Lessor to any assignment or subletting or if
Lessee shall request the consent of Lessor for any act Lessee proposes to do
then Lessee shall pay Lessor's reasonable attorney's fees incurred in connection
therewith, such attorney's fees not to exceed $350.00 for each such request.

13.     DEFAULT; REMEDIES.

        13.1    DEFAULT.  The occurrence of any one or more of the following
events shall constitute a material default of this Lease by Lessee:

                (a) The vacating or abandonment of the Premises by Lessee.

                (b) The failure by Lessee to make any payment of rent or any
other payment required to be made by Lessee hereunder, as and when due, where
such failure shall continue for a period of three (3) days after written notice
thereof from Lessor to Lessee.  In the event that Lessor serves Lessee with a
Notice to Pay Rent or Quit pursuant to applicable Unlawful Detainer statutes
such Notice to Pay Rent or Quit shall also constitute the notice required by
this subparagraph.

                (c) Except as otherwise provided in this Lease, the failure by
Lessee to observe or perform any of the covenants, conditions or provisions of
this Lease to be observed or performed by Lessee, other than described in
paragraph (b) above, where such failure shall continue for a period of thirty
(30) days after written notice thereof from Lessor to Lessee; provided, however,
that if the nature of Lessee's noncompliance is such that more than thirty (30)
days are reasonably required for its cure, then Lessee shall not be deemed to be
in default if Lessee commenced such cure within said thirty (30) day period and
thereafter diligently prosecutes such cure to completion. To the extent
permitted by law, such thirty (30) day notice shall constitute the sole and
exclusive notice required to be given to Lessee under applicable Unlawful
Detainer statutes.

                (d) (i) The making by Lessee of any general arrangement or
general assignment for the benefit of creditors; (ii) Lessee becomes a "debtor"
as defined in 11 U.S.C. Section 101 or any successor statute thereto (unless,
in the case of a petition filed against Lessee, the same is dismissed within
sixty (60) days); (iii) the appointment of a trustee or receiver to take
possession of substantially all of Lessee's assets located at the Premises or
of Lessee's interest in this Lease, where possession is not restored to Lessee
within thirty (30) days; or (iv) the attachment, execution or other judicial
seizure of substantially all of Lessee's assets located at the Premises or of
Lessee's interest in this Lease, where such seizure is not discharged within
thirty (30) days.  In the event that any provision of this paragraph 13.1(d) is
contrary to any applicable law, such provision shall be of no force or effect.

                (e) The discovery by Lessor that any financial statement given
to Lessor by Lessee, any assignee of Lessee, any subtenant of Lessee, any
successor in interest of Lessee or any guarantor of Lessee's obligation
hereunder, was materially false.

        13.2    REMEDIES.  In the event of any such material default by Lessee,
Lessor may at any time thereafter, with or without notice or demand and without
limiting Lessor in the exercise of any right or remedy which Lessor may have by
reason of such default:

                (a) Terminate Lessee's right to possession of the Premises by
any lawful means, in which case this Lease and the term hereof shall terminate
and Lessee shall immediately surrender possession of the Premises to Lessor.
In such event Lessor shall be entitled to recover from Lessee all damages
incurred by Lessor by reason of Lessee's default including, but not limited
to, the cost of recovering possession of the Premises, expenses of reletting,
including necessary renovation and alteration of the Premises, reasonable
attorney's fees, and any real estate commission actually paid; the worth at the
time of award by the court having jurisdiction thereof of the amount by which
the unpaid rent for the balance of the term after the time of such award
exceeds the amount of such rental loss for the same period that Lessee proves
could be reasonably avoided; that portion of the leasing commission paid by
Lessor pursuant to paragraph 15 applicable to the unexpired term of this Lease.

<PAGE>   6
                 (b)  Maintain Lessee's right to possession in which case this
Lease shall continue in effect whether or not Lessee shall have vacated or
abandoned the Premises.  In such event Lessor shall be entitled to enforce all
of Lessor's rights and remedies under this Lease, including the right to recover
the rent as it becomes due hereunder.

                 (c)  Pursue any other remedy now or hereafter available to
Lessor under the laws or judicial decisions of the state wherein the Premises
are located.  Unpaid installments of rent and other unpaid monetary obligations
of Lessee under the terms of this Lease shall bear interest from the date due at
the maximum rate then allowable by law.

         13.3 DEFAULT BY LESSOR.  Lessor shall not be in default unless Lessor
fails to perform obligations required of Lessor within a reasonable time, but in
no event later than thirty (30) days after written notice by Lessee to Lessor
and to the holder of any first mortgage or deed of trust covering the Premises
whose name and address shall have theretofore been furnished to Lessee in
writing, specifying wherein Lessor has failed to perform such obligation;
provided, however, that if the nature of Lessor's obligation is such that more
than thirty (30) days are required for performance then Lessor shall not be in
default if Lessor commences performance within such thirty (30) day period and
thereafter diligently prosecutes the same to completion.

         13.4 LATE CHARGES.  Lessee herby acknowledges that late payment by
Lessee to Lessor of Base Rent, Lessee's Share of Operating Expenses or other
sums due hereunder will cause Lessor to incur costs not contemplated by this
Lease, the exact amount of which will be extremely difficult to ascertain. Such
costs include, but are not limited to, processing and accounting charges, and
late charges which may be imposed on Lessor by the terms of any mortgage or
trust deed covering the Industrial Center.  Accordingly, if any installment of
Base Rent, Operating Expenses, or any other sum due from Lessee shall not be
received by Lessor or Lessor's designee within ten (10) days after such amount
shall be due, then, without any requirement for notice to Lessee, Lessee shall
pay to Lessor a late charge equal to 6% of such overdue amount. The parties
hereby agree that such late charge represents a fair and reasonable estimate of
the costs Lessor will incur by reason of late payment by Lessee. Acceptance of
such late charge by Lessor shall in no event constitute a waiver of Lessee's
default with respect to such overdue amount, nor prevent Lessor from exercising
any of the other rights and remedies granted hereunder.  In the event that a
late charge is payable hereunder, whether or not collected, for three (3)
consecutive installments of any of the aforesaid monetary obligations of Lessee,
then Base Rent shall automatically become due and payable quarterly in advance,
rather than monthly, notwithstanding paragraph 4.1 or any other provision of
this Lease to the contrary.

14.  CONDEMNATION.  If the Premises or any portion thereof or the Industrial
Center are taken under the power of eminent domain, or sold under the threat of
the exercise of said power (all of which are herein called "condemnation"), this
Lease shall terminate as to the part so taken as of the date the condemning
authority takes title or possession, whichever first occurs.  If more than ten
percent of the floor area of the Premises, or more than twenty-five percent of
that portion of the Common Areas designated as parking for the Industrial Center
is taken by condemnation, Lessee may, at Lessee's option, to be exercised in
writing only within ten (10) days after Lessor shall have given Lessee written
notice of such taking (or in the absence of such notice, within ten (10) days
after the condemning authority shall have taken possession) terminate this Lease
as of the date the condemning authority takes such possession.  If Lessee does
not terminate this Lease in accordance with the foregoing, this Lease shall
remain in full force and effect as to the portion of the Premises remaining,
except that the rent shall be reduced in the proportion that the floor area of
the Premises taken bears to the total floor area of the Premises.  No reduction
of rent shall occur if the only area taken is that which does not have the
Premises located thereon.  Any award for the taking of all or any part of the
Premises under the power of eminent domain or any payment made under threat of
the exercise of such power shall be the property of Lessor, whether such award
shall be made as compensation for diminution in value of the leasehold or for
the taking of the fee, or as severance damages; provided, however, that Lessee
shall be entitled to any award for loss of or damage to Lessee's trade fixtures
and removable personal property.  In the event that this Lease is not terminated
by reason of such condemnation, Lessor shall to the extent of severance damages
received by Lessor in connection with such condemnation, repair any damage to
the Premises caused by such condemnation except to the extent that Lessee has
been reimbursed therefor by the condemning authority.  Lessee shall pay any
amount in excess of such severance damages required to complete such repair.

15.  BROKER'S FEE.  Refer to Paragraph 59

         (a)   Upon execution of this Lease by both parties, Lessor shall pay to
N/A, Licensed Real Estate Broker(s), a fee as set forth in a separate agreement
between Lessor and said broker(s), or in the event there is no separate
agreement between Lessor and said broker(s), the sum of $         , for
brokerage services rendered by said broker(s) to Lessor in this transaction.

16.  ESTOPPEL CERTIFICATE.  Refer to Paragraph 60

         (a)    Each party (as "responding party") shall at any time upon not
less than ten (10) days' prior written notice from the other party ("requesting
party") execute, acknowledge and deliver to the requesting party a statement in
writing (i) certifying that this Lease is unmodified and in full force and
effect (or, if modified, stating the nature of such modification and certifying
that this Lease, as so modified, is in full force and effect) and the date to
which the rent and other charges are paid in advance, if any, and (ii)
acknowledging that there are not, to the responding party's knowledge, any
uncured defaults on the part of the requesting party, or specifying such
defaults if any are claimed.  Any such statement may be conclusively relied upon
by any prospective purchaser or encumbrancer of the Premises or of the business
of the requesting party.

         (b)    At the requesting party's option, the failure to deliver such
statement within such time shall be a material default of this Lease by the
party who is to respond, without any further notice to such party, or it shall
be conclusive upon such party that (i) this Lease is in full force and effect,
without modification except as may be represented by the requesting party; (ii)
there are no uncured defaults in the requesting party's performance, and (iii)
if Lessor is the requesting party, not more than one month's rent has been paid
in advance.

         (c)    If Lessor desires to finance, refinance, or sell the Industrial
Center, or any part thereof, Lessee hereby agrees to deliver to any lender or
purchaser designated by Lessor such financial statements of Lessee as may be
reasonably required by such lender or purchaser.  Such statements shall include
the past three (3) years' financial statements of Lessee.  All such financial
statements shall be received by Lessor and such lender or purchaser in
confidence and shall be used only for the purposes herein set forth.

17.  LESSOR'S LIABILITY.  The term "Lessor" as used herein shall mean only
General Atomics.  The obligations contained in this Lease to be performed by
Lessor shall, subject as aforesaid, be binding on Lessor's successors and
assigns.

18.  SEVERABILITY.  The invalidity of any provision of this Lease as determined
by a court of competent jurisdiction, shall in no way affect the validity of
any other provision hereof.

19.  INTEREST ON PAST-DUE OBLIGATIONS.  Except as expressly herein provided, any
amount due to Lessor not paid when due shall bear interest at the maximum rate
then allowable by law from the date due.  Payment of such interest shall not
excuse or cure any default by Lessee under this Lease; provided, however, that
interest shall not be payable on late charges incurred by Lessee nor on any
amounts upon which late charges are paid by Lessee.

20.  TIME OF ESSENCE.  Time is of the essence with respect to the obligations
to be performed under this Lease.

21.  ADDITIONAL RENT.  All monetary obligations of Lessee to Lessor under the
terms of this Lease, including but not limited to Lessee's Share of Operating
Expenses and insurance and tax expenses payable shall be deemed to be rent.

22.  INCORPORATION OF PRIOR AGREEMENTS; AMENDMENTS.  This Lease contains all

24.     WAIVERS.  No waiver by lessor or any provision hereof shall be deemed a
waiver of any other provision hereof or of any subsequent breach by Lessee of
the same or any other provision.  Lessor's consent to, or approval of, any act
shall not be deemed to render unnecessary the obtaining of Lessor's consent to
or approval of any subsequent act by Lessee.  The acceptance of rent hereunder
by Lessor shall not be a waiver of any preceding breach by Lessee of any
provision hereof, other than the failure of Lessee to pay the particular rent
so accepted, regardless of Lessor's knowledge of such preceding breach at the
time of acceptance of such rent.

25.     RECORDING.

26.     HOLDING OVER.  If Lessee, with Lessor's consent, remains in possession
of the Premises or any part thereof after the expiration of the term hereof,
such occupancy shall be a tenancy from month to month upon all the provisions
of this Lease pertaining to the obligations of Lessee, but all Options, if any,
granted under the terms of this Lease shall be deemed terminated and be of no
further effect during said month to month tenancy.  Base Rent specified in
Paragraph 4.1 during holdover period shall be 125% of rent for the month
immediately preceding start of the holdover period.

27.     CUMULATIVE REMEDIES.  No remedy or election hereunder shall be deemed
exclusive but shall, wherever possible, be cumulative with all other remedies
at law or in equity.

28.     COVENANTS AND CONDITIONS.  Each provision of this Lease performable by
Lessee shall be deemed both a covenant and a condition.

29.     BINDING EFFECT; CHOICE OF LAW.  Subject to any provisions hereof
restricting assignment or subletting by Lessee and subject to the provisions of
paragraph 17, this Lease shall bind the parties, their personal
representatives, successors and assigns.  This Lease shall be governed by the
laws of the State where the Industrial Center is located and any litigation
concerning this Lease between the parties hereto shall be initiated in the
county in which the Industrial Center is located.

30.     SUBORDINATION.

        (a)     This Lease, and any Option granted hereby, at Lessor's option,
shall be subordinate to any ground lease, mortgage, deed of trust, or any other
hypothecation or security now or hereafter placed upon the Industrial Center
and to any and all advances made on the security thereof and to all renewals,
modifications, consolidations, replacements and extensions thereof.
Notwithstanding such subordination, Lessee's right to quiet possession of the
Premises shall not be disturbed if Lessee is not in default and so long as
Lessee shall pay the rent and observe and perform all of the provisions of this
Lease, unless this Lease is otherwise terminated pursuant to its terms.  If any
mortgagee, trustee or ground lessor shall elect to have this Lease and any
Options granted hereby prior to the lien of its mortgage, deed of trust or
ground lease, and shall give written notice thereof to Lessee, this Lease and
such Options shall be deemed prior to such mortgage, deed of trust or ground
lease, whether this Lease or such Options are dated prior or subsequent to the
date of said mortgage, deed of trust or ground lease or the date of recording
thereof.

        (b)     Lessee agrees to execute any documents required to effectuate
an attornment, a subordination or to make this Lease or any Option granted
herein prior to the lien of any mortgage, deed of trust or ground lease, as the
case may be.  Lessee's failure to execute such documents within ten (10) days
after written demand shall constitute a material default by Lessee hereunder
without further notice to Lessee or, at Lessor's option, Lessor shall execute
such documents on behalf of Lessee as Lessee's attorney-in-fact.  Lessee does
hereby make, constitute and irrevocably appoint Lessor as Lessee's
attorney-in-fact and in Lessee's name, place and stead, to execute such
documents in accordance with this paragraph 30(b).

31.     ATTORNEY'S FEES.  If either party or the broker(s) named herein bring
an action to enforce the terms hereof or declare rights hereunder, the
prevailing party in any such action, on trial or appeal, shall be entitled to
his reasonable attorney's fees to be paid by the losing party as fixed by the
court.  The provisions of this paragraph shall inure to the benefit of the
broker named herein who seeks to enforce a right hereunder.

32.     LESSOR'S ACCESS.  Lessor and Lessor's agents shall have the right to
enter the Premises at reasonable times for the purpose of inspecting the same,
showing the same to prospective purchasers, lenders, or lessees, and making
such alterations, repairs, improvements or additions to the Premises or to the
Industrial Center as Lessor may deem necessary or desirable.  Lessor may at any
time, place on or about the Premises or the Building any ordinary "For Sale"
signs and Lessor may at any time during the last 120 days of the term hereof
place on or about the Premises any ordinary "For Lease" signs.  All activities
of Lessor pursuant to this paragraph shall be without abatement of rent, nor
shall Lessor have any liability to Lessee for the same.

33.     AUCTIONS.  Lessee shall not conduct, nor permit to be conducted, either
voluntarily or involuntarily, any auction upon the Premises or the Common Areas
without first having obtained Lessor's prior written consent.  Notwithstanding
anything to the contrary in this Lease, Lessor shall not be obligated to
exercise any standard of reasonableness in determining whether to grant such
consent.

34.     SIGNS.  Lessee shall not place any sign upon the Premises or the
Industrial Center without Lessor's prior written consent.  Under no
circumstances shall Lessee place a sign on any roof of the Industrial Center.

35.     MERGER.  The voluntary or other surrender of this Lease by Lessee, or a
mutual cancellation thereof, or a termination by Lessor, shall not work a
merger, and shall, at the option of Lessor, terminate all or any existing
subtenancies or may, at the option of Lessor, operate as an assignment to
Lessor of any or all of such subtenancies.

36.     CONSENTS.  Except for paragraph 33 hereof, wherever in this Lease the
consent of one party is required to an act of the other party such consent
shall not be unreasonably withheld or delayed.

37.     GUARANTOR.  In the event that there is a guarantor of this Lease, said
guarantor shall have the same obligations as Lessee under this Lease.

38.     QUIET POSSESSION.  Upon Lessee paying the rent for the Premises and
observing and performing all of the covenants, conditions and provisions on
Lessee's part to be observed and performed hereunder, Lessee shall have quiet
possession of the Premises for the entire term hereof subject to all of the
provisions of this Lease.  The individuals executing this Lease on behalf of
Lessor represent and warrant to Lessee that they are fully authorized and
legally capable of executing this Lease on behalf of Lessor and that such
execution is binding upon all parties holding an ownership interest in the
Industrial Center.

39.     OPTIONS.  Refer to Paragraph 62

        39.1    DEFINITION.  As used in this paragraph the word "Option" has
the following meaning: the right or option to expand the Premises consolidate
in Building 9 Premises and surrender Building 2 Premises and terminate plans to
expand to Building 9.

        39.2    OPTIONS PERSONAL.  Each Option granted to Lessee in this Lease
is personal to the original Lessee and may be exercised only by the original
Lessee while occupying the Premises who does so without the intent of
thereafter assigning this Lease or subletting the Premises or any portion
thereof, and may not be exercised or be assigned, voluntarily or involuntarily,
by or to any person or entity other than Lessee, provided, however, that an
Option may be exercised by or assigned to any Lessee Affiliate as defined in
paragraph 12.2 of this Lease.  The Options, if any, herein granted to Lessee
are not assignable separate and apart from this Lease, nor may any Option be
separated from this Lease in any manner, either by reservation or otherwise.

        39.3    MULTIPLE OPTIONS.  In the event that Lessee has any multiple
options to extend or renew this Lease a later option cannot be exercised unless
the prior option to extend or renew this Lease has been so exercised.

        39.4    EFFECT OF DEFAULT ON OPTIONS.

                (a)     Lessee shall have no right to exercise an Option,
notwithstanding any provision in the grant of Option to the contrary, (i)
during the time commencing from the date Lessor gives to Lessee a notice of
default pursuant to paragraph 13.1(b) or 13.1(c) and continuing until the
noncompliance alleged in said notice of default is cured, or (ii) during the
period of time commencing on the date after a monetary obligation to Lessor is
due from Lessee and unpaid (without any necessity for notice thereof to Lessee)
and continuing until the obligation is paid, or (iii) at any time after an
event of default described in paragraphs 13.1(a), 13.1(d), or 13.1(e) (without
any necessity of Lessor to give notice of such default to Lessee), or (iv) in
the event that Lessor has given to Lessee three or more notices of default
under paragraph 13.1(b) or paragraph 13.1(c), whether or not the defaults are
cured, during the 12 month period of time immediately prior to the time that
Lessee attempts to exercise the subject Option.

                (b)     The period of time within which an Option may be
exercised shall not be extended or enlarged by reason of Lessee's inability to
exercise an Option because of the provisions of paragraph 39.4(a).

                (c)     All rights of Lessee under the provisions of an Option
shall terminate and be of no further force or effect, notwithstanding Lessee's
due and timely exercise of the Option, if, after such exercise and during the
term of this Lease, (i) Lessee fails to pay to Lessor a monetary obligation of
Lessee for a period of thirty (30) days after such obligation becomes due
(without any necessity of Lessor to give notice thereof to Lessee), or (ii)
Lessee fails to commence to cure a default specified in paragraph 13.1(c) within
thirty (30) days after the date that Lessor gives notice to Lessee of such
default and/or Lessee fails thereafter to diligently prosecute said cure to
completion, or (iii) Lessee commits a default described in paragraphs 13.1(a),
13.1(d) or 13.1(e) (without any necessity of Lessor to give notice of such
default to Lessee), or (iv) Lessor gives to Lessee three or more notices of
default under paragraph 13.1(b), or paragraph 13.1(c), whether or not the
defaults are cured.

40.     SECURITY MEASURES.  Lessee hereby acknowledges that Lessor shall have
no obligation whatsoever to provide guard service or other security measures
for the benefit of the Premises or the Industrial Center.  Lessee assumes all
responsibility for the protection of Lessee, its agents, and invitees and the
property of Lessee and of Lessee's agents and invitees from acts of third
parties.  Nothing herein contained shall prevent Lessor, at Lessor's sole
option, from providing security protection for the Industrial Center or any
part thereof.

grant such easements, rights and dedications that Lessor deems necessary or
desirable, and to cause the recordation of Parcel Maps and restrictions, so long
as such easements, rights, dedications, Maps and restrictions do not
unreasonably interfere with the use of the Premises by Lessee. Lessee shall sign
any of the aforementioned documents upon request of Lessor and failure to do so
shall constitute a material default of this Lease by Lessee without the need for
further notice to Lessee.

42.     PERFORMANCE UNDER PROTEST. If at any time a dispute shall arise as to
any amount or sum of money to be paid by one party to the other under the
provisions hereof, the party against whom the obligation to pay the money is
asserted shall have the right to make payment, under protest, and such payment
shall not be regarded as a voluntary payment, and there shall survive the right
on the part of said party to institute suit for recovery of such sum. If it
shall be adjudged that there was no legal obligation on the part of said party
to pay such sum or any part thereof, said party shall be entitled to recover
such sum or so much thereof as it was not legally required to pay under the
provisions of this Lease.

"Lessee" means "Sublessee."

48.     Insert to Paragraphs 3.2 Delay of Possession and 3.3 Early Possession
and 6.2(a) Compliance with Law (as it applies to warranty.)

Parties agree that Paragraphs 3.2, Delay of Possession, 3.3, Early Possession
and 6.2(a) Compliance with Law (as it applies to warranty), do not apply to
Lessee's "CURRENT" premises since Lessee took possession during a period
starting May 31, 1991 and ending June 30, 1994. Warranty provisions of 6.2(a)
shall apply to Buildings 2 and 9 "ADDED" space.

49.     Insert to Paragraph 6.2(a) Compliance with Law

Lessee agrees to accept the Premises subject to a Master Lease and all
applicable zoning, municipal, county, state and federal laws, ordinances, and

Lease are in full force and effect.

50.     Insert to Paragraph 6.2(b) Compliance with Law

50.1    Lessee shall not use the Premises for processing, storage or production
of "Hazardous Substances" (as defined below) without the express written consent
of the Lessor. "Hazardous Substance" means (a) any substance that is toxic,
explosive, corrosive, flammable, infectious, radioactive, carcinogenic,
mutagenic or otherwise hazardous, and is, or becomes, regulated by any
government authority, department, commission, board, agency or instrumentality
of the United States, the State of California or any political subdivision
thereof; (b) any other substance, the presence of which requires investigation
or remediation under any federal, state or local statute, regulation, ordinance,
order, action of common law; and (c) any additional substances or materials
which at such time are classified or considered to be hazardous or toxic under
the Laws of California or any other applicable Laws relating to the Premises.
Lessee shall coordinate any permit application for use and handling of Hazardous

Lessor, Lessee shall submit a list and material data sheet for all Hazardous
Substances maintained in the Premises.

50.2    Lessor and its representative agents shall have the right to enter the
Premises at reasonable times for the purpose of inspecting the same for

50.3    Hazardous Substances produced by Lessee shall be the responsibility of
Lessee, and Lessee shall dispose of such Hazardous Substances in accordance with

Practices, and in a safe and reasonable manner, both during the term of the
Lease, when required or appropriate, but in no event later than the date that
the Lease is terminated.

50.4    Lessee shall cooperate with Lessor to implement a policy, prepared by
the Lessor and acceptable to the City of San Diego, whereby the storage,
dispensing, use and handling of hazardous materials and flammable gases are in
compliance with the Uniform Building and Uniform Fire Codes. Final resolution
may require one or a combination of the following: reducing the amount of
inventory in common areas; establishing control areas to store materials
within the premises; sharing storage in a specially designed hazardous material
storage room established by the Lessor with its use charged as an operating
expense to the Lessee.

Any equipment installed outside the building shall receive the Lessor's consent
and approval. Cost for alterations, installation, service,

maintenance or other operating expenses including that required for removal and
cleanup for such tenant fixtures or equipment, shall be borne by the Lessor.

50.5  Lessor's written consent under Paragraph 50.1 shall be documented by
satisfactory results from inspections performed by the Lessor, local, state and
federal agencies, and inspections performed on behalf of insurance companies,
lenders and owners holding interest in the real property; Specifically, Lessor
shall show its concurrence by quarterly inspection of space under State
Radiological License and by resolution of any adverse findings resulting from
the quarterly and annual inspections confirming Lessee's compliance with policy
established to control "Hazardous Substances" and acceptable use of the
premises.

51.  Insert to Paragraph 6.3(b), Condition of Premises

Parties agree Paragraph 6.3(b), Condition of Premises does not apply to the
Lessee's "CURRENT" premises since Lessee has been in possession of said
premises under terms of the Sublease and subsequent Amendments (Paragraph 61)
that modified the terms and size of the premises.

52.  Insert to Paragraph 7.2(a), Lessee's Obligations

52.1  Lessee agrees to conduct day-to-day operations of the premises in a
manner to preserve the integrity of building structures and its systems
including, fire barriers, heating, air-conditioning and ventilation systems and
other installed utilities.  Specifically, Lessee agrees to keep exterior doors
closed at all times, except for passage; keep windows closed at all times; keep
doors separating laboratories from office corridors and service corridors
closed at all times, except with used for passage; and to limit heat loads and
laboratory exhaust ventilating rates within Building and system design limits.


Lessee's Building 2, "CURRENT" and "ADDED" premises, are served from central
heating, ventilating and air conditioning zones S-2 and S-3.  Zone S-2 serves
the laboratories and provides 100% outside conditioned air.  Zone S-3 serves
the offices and corridor with circulated air using approximately 20%
conditioned outside air.  Lessee shall cooperate with Lessor to implement a
policy, prepared by the Lessor, whereby changes to the Building 2 ventilation
system are controlled to insure prudent laboratory practices are implemented to
comply with applicable codes and standards.  Provisions of the policy allows
the Lessee flexibility to divert air supply and ventilation within its
laboratory space block on condition that this diversion complies with codes and
standards, spaces are contiguous, the diversion does not affect other users in
the ventilation zone, and the physical changes are removed and the system
restored to its original condition by the Lessee upon surrender of the
premises.  Following are the ventilation rates assigned to the Building 2
laboratory spaces.

Lessee's Building 9 "ADDED" premises currently exists in shell condition and
shall be improved in accordance with working drawings and specification jointly
developed by parties to this Lease Agreement.  Laboratory space shall be
designed with a ventilation system using 100% outside air or variable volume or
auxiliary conditioned air, all separate from the administrative space.
Administrative space will likely be designed to be served by a system wherein
approximately 20% outside air is conditioned and circulated.  Ventilation rates
for the laboratories shall be recorded as established design limits in a Lease
Amendment prepared and executed to document Lessee's term commencement for
Building 9 premises.

In those cases where exhaust and ventilation rates, or heat loads, served from
Lessor's central system, are exceeded, Lessee shall take action to bring
ventilation rates and heat loads within design conditions, all at the Lessee's
sole expense.  Operating costs associated with maintenance, repair and utility
supply of said equipment shall be borne by the Lessee.

52.2  For Building 2 premises, Lessee's obligations to maintain plumbing,
heating, ventilating and air conditioning systems, electrical and lighting
facilities and equipment within the premises is interpreted to include Lessee's
machinery, equipment or fixtures which the Lessee has or will install during
its tenancy, or for that equipment which Lessee has assumed the obligation as
an assignee from a previous tenant, or that which is non-standard to Lessor's
offering.  In situ, non-standard equipment owned by the Lessor, or machinery,
equipment or fixtures installed by the Lessee, all considered by the Lessor as
serving the function of supplementing Lessee's specific use of the premises, is
determined by the Lessor as being the Lessee's obligation under this section of
the Lease.

For Building 9 space, it shall be the Lessee's responsibility to operate,
maintain and repair all laboratory mechanical, plumbing, electrical and other
improvements from point of use to the point of connection at the exterior of the
premises serving the Leasehold.  In addition, Lessee shall be responsible to
operate, maintain and repair all space improvements including flooring, walls,
ceilings, doors, windows, hardware and its own fixtures, equipment and systems.

52.3  For that part of the Lessee's premises served by Lessor's central
heating, ventilation and air-conditioning (HVAC) systems, in either Buildings 2
or 9, Lessor shall operate equipment and systems needed to supply conditioned
air to the interior spaces between the hours of 6:00AM to 6:00PM, except on
National Holidays and during scheduled outages or breakdowns.  Exhausters for
the laboratory spaces shall be operated twenty four hours per day, seven days a
week, except for scheduled outages or breakdowns.  Lessee shall plan its
operations accordingly.

For that part of the Lessee's premises served by dedicated or supplemental
HVAC, in either Building 2 or 9, Lessee shall operate equipment at its own
discretion, as long as such operation does not affect other building users or
common areas.

53.  Insert to Paragraph 7.2(c), Lessee's Obligations

53.1  For Building 2, Lessee took possession of the "CURRENT" premises by Lease
and subsequent Amendments spanning a period of approximately three years (Refer
to Paragraph 61) and agrees to perform to the obligations of this new Lease
dating back to that date of possession for the respective space blocks.

53.2  For Building 9 "ADDED" space, Lessee accepts the premises in the
condition existing upon substantial completion of leasehold improvements.  For
all other "ADDED" or "EXPANSION" space, Building 2 or 9, Lessee accepts the
premises in the condition existing upon possession.

54.  Insert to Paragraph 7.3(a), Alterations and Additions

54.1  For Building 2, Date of Possession of "CURRENT" space is defined as the
date of Lessee's original Lease.  (Refer to Paragraph 61)

54.2  For Building 9, Date of Possession of "ADDED" space is defined as the
date of completion of substantial leasehold improvements.  Lessor accepts
condition of premises with leasehold improvements installed in accordance with
the provisions stated and agreed upon in the WORK LETTER AGREEMENT, contained
herein as Exhibit F (Pages 1-6).


54.3  Alterations, improvements, additions or utility installations by the
Lessee shall be performed by licensed and insured construction or service
companies having qualified craftworkers possessing the proper qualifications
and training for performing the work.  Alterations, improvements, additions or
utility installations shall be performed by contractors for which Lessor has
given Lessee its consent. Firms engaged in performing services for the Lessor
on Blanket Order Service Agreements are pre-qualified to perform services for
the Lessee.

55.  Insert to Paragraph 8.4, Payment of Premium Increase

Lessee shall reimburse Lessor for the increase of insurance premium assessed by
Lessor's insurance carrier caused by or directly attributable, totally or in
part, to Lessee's activities or use of the Premises, as it

                                                                Initials_______

relates to use, handling and storage of radiological and hazardous materials.
The amount of accessed premium to Lessee shall be calculated by its prorata
share of the space occupied by Lessee on the effective date of invoice from the
insurance carrier, without offset for partial year possession or change of use
of its premises.  If the assessment is likewise attributable to similar use of
its Premises by other tenants, the assessment shall be prorated based on the
area encumbered by said activities.  If the assessment is attributable to a
specific tenant's use, the premium increase shall be assessed to that specific
tenant.

56 (a).  Insert to Paragraph 8.7 Indemnity

Lessor shall protect, defend and hold harmless Lessee and Lessee's employees,
officer, agents, directors, and shareholders, and the successors and assigns of
each of the foregoing, against and from any and all claims, demands, losses
liabilities, damages, costs and expenses, (including, without limitation,
attorneys' and consultants' fees and the costs and expenses of defense) arising
or resulting from (i) Lessor's or Lessor's Agents' breach of any covenant,
representation or warranty under this Lease, (ii) Lessee's or Lessors' Agents
negligence or willful misconduct.  The mutual indemnity obligations of Lessor
and Lessee under this Lease shall not, however, release the respective insurers
of Lessor and Lessee from such insurers' obligations under any policies
covering their respective insureds.

56 (b).  Insert to Paragraph 8.8 Exemption of Lessor From Liability

Except for planned outages that are conducted by the Lessor for the purpose of
altering or maintaining its Buildings or private service systems of the
"Industrial Center," Lessee hereby agrees that the Lessee shall be responsible
for making any necessary provisions that may be required for standby utility
services, considered critical to Lessee's operations or use of the premises in
the event electrical power, air, water, sewer, gas, telephone or other Lessor
supplied services are interrupted.

57.  Insert to Paragraph 10, Real Property Taxes

57.1  Paragraph 10 shall apply only to that space designated "ADDED" and
"EXPANSION" Space Building 9 (Exhibit B); Lessee shall reimburse Lessor for
prorata share of real property taxes.  The tax bill for the "Industrial Center"
includes tax assessments for three parcels; one for Genesee Properties and two
for Hopkins Properties.  Building 9 is located on the Genesee Properties parcel
which includes buildings with combined space of 501,757 GSF.  Lessee's share of
taxes shall be calculated using the Genesee Properties, Inc. tax bill for the
period July 1, 1993 through June 30, 1994 adjusted in accordance with
Paragraph 10.

57.2  Lessor shall be solely responsible for any increases in Real Property
Taxes/or assessments that result from change of ownership of the Building or
Industrial Center, redevelopment, or for any new construction except for any
supplemental tax assessment that may be levied specifically for the leasehold
improvements of Lessee's Building 9 "ADDED" space in which case the
supplemental premium shall be paid by Lessee.

58.  Insert to Paragraph 11, Utilities

58.1  For the space designated "CURRENT" and "ADDED" Space Building 2, ordinary
utilities including electric, gas, water and sewer, are included in the base
rent.  If in the Lessor's reasonable opinion, Lessee's utility usage in these
areas exceeds that which Lessor considers normal building usage, (ordinary
utility usage), Lessor shall have the option to meter or calculate such usage
(extraordinary utility usage) and charge Lessee a monthly operating expense
equal to the actual cost charged to the Lessor.  For purposes of determining
extraordinary utility usage, Lessor shall apply what is considered normal
standards for lighting and convenience utility usage, and the criteria used for
design of the building heating, air conditioning, exhaust and ventilation
systems.  Extraordinary utility usage is generally judged to be that usage
needed to supplement operation of Lessee's special or added equipment installed
to support special laboratory operations, supply Lessee's special heating,
ventilation and air conditioning, refrigeration [reference Paragraph 52.2],
autoclaves, process

pumping, water purification, deionized water source, and the like.  If the
Lessor elects to use the calculation method of determining extraordinary usage,
Lessee shall have the right, at its own expense, to cause the Premises or
equipment to be separately metered in order to determine the extraordinary
usage.

58.2.  Lessee's Building 9 space currently exists in shell condition and shall
be improved in accordance with working drawings and specifications jointly
developed by parties to this Lease Agreement (Refer to Exhibit B).  To the
extent practical and economical, utility usage in the Lessee's premises shall
be metered so utility costs can be passed through to the Lessee based on
consumption measured using submeters.  In those cases where submetering is
impractical or too costly, usage shall be charged on a prorate basis as covered
in Exhibit E.

58.3  Lessee shall use Lessor's telephone service and shall pay for
installation, moves, changes and monthly services attributable to Lessee,
including all toll charges.  Charges for service and equipment are subject to
reasonable annual increases but shall not exceed the standard amounts charged to
other tenants in the "Industrial Center," for such services and equipment.
Parties agree that the 1994 calendar year equipment and service costs shall be
in accordance with the following schedule:

        Equipment Rental

        Telephone:  $30 per instrument/mo.
        Modem Line:  $30/mo.

        Adds, Moves and Changes

                Program/Designation Change:  $20/set
                Long Handset/Line Cords:  $20/set

Parties agree that reasonable annual adjustments, the same as applied to other
"Industrial Center" tenants, can be made without prior notice effective January
of each calendar year.

Charges for telephone rental, services, and toll calls and extraordinary
utilities shall be invoiced monthly by Lessor and shall be due and payable by
Lessee in accordance with Paragraph 21.

59.  Insert to Paragraph 15, Broker's Fee

Lessee represents and warrants to Lessor that it has not engaged any broker,
finder, or other person who would be entitled to any commission or fees in
respect to the negotiation, execution or delivery of this Sublease and shall
indemnify and hold harmless Lessor against any loss, cost, liability, or expense
incurred by Lessor as a result of any claim asserted by any broker, finder, or
other person on the basis of any arrangements made or alleged to have been made
by or on behalf of Lessee.

60.  Insert to Paragraph 16, Estoppel Certificate

Upon request of Master Lessor, or on behalf of the "Industrial Center" owner,
Lessee shall subordinate its interest in the Lease and the Premises to the
encumbrance instruments of any loans made to Lessor or owner.  Lessee shall
attorn to any purchaser at any foreclosure sale, or to any grantee or
transferee designated in any deed given in lieu of foreclosure.  Lessee shall
execute a subordination agreement and any other documents required by any
lender of Master Lessor to accomplish the purposes of this Section.

62.1  Option to Expand

Lessee shall be granted "Right of First Offer" ("ROFO") for administrative
space on the second floor of Building 9 designated as "EXPANSION" space,
Exhibit B.

      (a)  If the Lessor desires to offer part or all "ROFO" space for lease,
Lessor shall deliver a written notice to the Lessee, specifying the expansion
space block, and the terms of the offer.

      (b)  Lessee shall respond within (30) days.  If the Lessee fails to
accept or reject such an offer within (30) thirty days, then Lessor shall be
allowed to lease said space to other third parties.

      (c)  Rejection of the offer shall be in writing to the Lessor stipulating
the reason for rejection of the offer.

      (d)  If the Lessee fails to respond within the given period, Lessor shall
interpret Lessee's lack of response as a rejection and Lessee's "Right of First
Offer" for said space shall terminate for the remaining period of the Lease or
one year, whichever is shorter.

      (e)  The right to expand shall be granted only after Lessor's review of
Lessee's financial statement to establish Lessor's satisfaction that Lessee has
the ability to pay for rental and operating expenses for the offered space.

      (f)  The right to expand shall be granted only upon consent of the
Property Owner, and its lender, as expansion rights relate to the use of the
property, subordination, Lease term and financial consideration.

Parties agree that "ROFO" shall not apply to part or all of the space that may
be used by Lessor's affiliates.

62.2  Option to Surrender Building 2 Premises

Lessor grants to Lessee the option to surrender part or all of Lessee's
premises in Building 2, on condition that any space retained by the Lessee
shall be contiguous, that the retained space be comprised of a block starting
with Lab space number 564 and office space 565, and that the mix of surrendered
office and laboratory space be consistent with Lessor's reasonable use of the
surrendered space for lease to third parties.  Lessee shall give Lessor ninety
(90) days advanced written notice of its intent to retain Building 2 space.  If
Lessee fails to notify Lessor in writing of its intent to retain space, this
option shall be assumed executed by the Lessee and Lessor shall proceed on the
basis that all space in Building 2 will be surrendered by the Lessee thirty
(30) days after possession of

Building 9 "ADDED" premises.  Parties to this Agreement shall execute a Lease
Amendment identifying that space to be retained and any amended terms of the
Lease Agreement.

62.3  Option to Terminate Lease of Building 9 "ADDED" Space

Genesee Properties has agreed to finance leasehold improvements in the amount
not to exceed $100 per gross square feet of "ADDED" leased space in Building 9.
Lessee's monthly costs to service payment of the leasehold debt has been
determined using the promised funding.  Parties acknowledge that execution of
this lease agreement precedes completion of working drawings and specifications
that will lead to a project cost estimate that can be used to validate the
Lessee's expenses. In the event that cost of improvements exceed 110% of
promised financing and if after reviewing alternatives of reducing cost of
leasehold improvements to within 110% promised financing, Lessee determines
that cost of the leasehold improvements are beyond its capability to pay, then
Lessee has the option to terminate its agreement to lease Building 9 premises
on condition that the Lessee notifies the Lessor in writing within thirty (30)
days after receipt of the estimate and pays for all Lessors', and Genesee
Properties', costs expended to date, including and limited to: cost of design;
cost for producing documents, permit fees; cost of preparing the project
estimate; and loss of base rent for the Building 9 "ADDED" premises for the
30-day delay period.

     63   RENT ESCALATIONS

     (a) On each anniversary date of the Lease (July 1 of each year) the monthly
rent payable under paragraph 4 of the attached Lease shall be adjusted by the
increase, if any, from the date this Lease commenced, in the Consumer Price
Index of the Bureau of Labor Statistics of the U.S. Department of Labor for
Urban Wage Earners and Clerical Workers, Los Angeles-Long Beach-Anaheim,
California (1967 = 100), "All Items", herein referred to as "C.P.I."

     (b) The monthly rent payable in accordance with paragraph (a) of this
Addendum shall be calculated as follows: the rent payable for the first month of
the term of this Lease, as set forth in paragraph 4 of the attached Lease, shall
be multiplied by a fraction the numerator of which shall be the C.P.I. of the
calendar month during which the adjustment is to take effect, and the
denominator of which shall be the C.P.I. for the calendar month in which the 
original Lease term commences. The sum so calculated shall constitute the new 
monthly rent hereunder, but in no event, shall such new monthly rent be less 
than the rent payable for the month immediately preceding the date for rent 
adjustment.

     (c) Pending receipt of the required C.P.I. and determination of the actual
adjustment, Lessee shall pay an estimated adjusted rental, as reasonably
determined by Lessor by reference to the then available C.P.I. information. Upon
notification of the actual adjustment after publication of the required C.P.I.,
any overpayment shall be credited against the next installment of rent due, and
any underpayment shall be immediately due and payable by Lessee. Lessor's
failure to request payment of an estimated or actual rent adjustment shall not
constitute a waiver of the right to any adjustment provided for in the Lease or
this addendum.

     (d) In the event the compilation and/or publication of the C.P.I. shall be
transferred to any other governmental department or bureau or agency or shall be
discontinued, then the index most nearly the same as the C.P.I. shall be used to
make such calculation. In the event that Lessor and Lessee cannot agree on such
alternative index, then the matter shall be submitted for decision to the
American Arbitration Association in accordance with the then rules of said
association and the decision of the arbitrators shall be binding upon the
parties. The cost of said Arbitrators shall be paid equally by Lessor and
Lessee.

     (e) For Building 2 Premises, the Base Rent under (b) above shall be capped
by an increase of 4% minimum and 8% maximum.

                             WORK LETTER AGREEMENT

In consideration of the terms and conditions of the Sublease by and between
General Atomics (Lessor) and Alanex Corporation (Lessee) dated July 1, 1994,
the parties agree to the terms specified in this Work Letter Agreement. The
Work Letter Agreement is written to complement the Form Sublease and its
Addenda; it expands and elaborates on the Form Sublease with no conflict
intended. 

General Atomics (GA) will deliver to Alanex Corporation (Alanex) Building 9
space, common area and building services suitable for conversion to biotech use
under the following provisions:

                                I. BASE BUILDING

Description: The space will be comprised of two contiguous "High Bay" spaces,
one "Low Bay" space and two equipment enclosures.

A. The "High Bay" space is comprised of two bays (Bays 2 & 3) currently in a
"Building shell" condition. Bay #2 measures approximately 4440gsf, Bay #3
measures approximately 4534gsf and both provide an overhead clearance of
approximately 29 ft. floor to deck. The existing overhead crane will be removed
or parked in place, and will not serve any on-going function to the Alanex 
Leasehold. Existing ventilation exhaust units, lighting, fire protection, and 
electrical services will be left in place to serve the space during 
installation of Leasehold Improvements and common space as dictated by the 
design. The interspace between laboratory structure and building roof deck 
will be used to house laboratory mechanical, electrical, piping and support
systems equipment and to provide access to other building users of the
interspace in Bay #1 and second floor improved space.

"Low Bay" space (Bay #4) is comprised of approximately 1224gsf of shell space,
2627gsf of previously improved administrative space, and common space to be
retained by the Lessor to serve the Lessee and other users. Overhead clearance
in this Bay is approximately 15 ft. from floor level to the overhead deck
forming the floor support structure for second level office space. Ventilation
ducting and other services will be installed in a manner to use Bays #2 & #3
interspace for points of connection to Bay #4 space and equipment.

Outside service enclosures are available for placement of mechanical and
electrical equipment and storage as needed to serve the Alanex Leasehold
Improvements. One enclosure is shared with other building occupants and its use
will be charged based on that portion assigned to the respective occupant. The
second enclosure is shared with the Lessor and its use will be charged based on
a monthly prorated basis according to floor space occupied.

B. Points of connection will be provided to site and building services having
sufficient capacity to serve the Alanex Leasehold. This will include commercial
electrical power, natural gas, potable water, fire water, sewer and telephone.
Connection to these services will be provided at a point near to or within the
exterior walls of the building. Fresh air will be provided to the space from
the south or west building exterior and exhausted through the building roof in
the easterly direction. New laboratories will be designed to discharge rejected
heat to the building exterior and not inside the High Bay interspace.

C. Alanex will be provided non-exclusive access to the Building 9 service yard,
to the outside service enclosures, to service corridors serving its premises
and the interstitial space above the laboratories. Alanex will be given
permission to install a chemical storage container, if allowed by building
permit, which is architecturally acceptable and located to the satisfaction of
General Atomics and permitting agencies. Such an enclosure is

classified as a tenant fixture and installation of services such as power,
water and alarms will be borne by Alanex.

D.      Alanex will have non-exclusive use of the existing loading dock and
ramp located in the Building 9 service yard for use in shipping and receiving
operations. Storage on the loading dock or in the service yard is not allowed
unless material is in process of being shipped or received or Alanex has
received express written approval from General Atomics for such storage.

E.      If Alanex leases second floor "EXPANSION" space, Alanex will have
non-exclusive use of heating, air conditioning, and mechanical equipment in
place and currently used for space conditioning of the office and common space.

                           II. LEASEHOLD IMPROVEMENTS

General Atomics will cause to be installed and Genesee Properties will finance
Leasehold Improvements required to convert the premises for Alanex use.
Financing will be provided for improvements that are generic to biotech use,
are of value to the realty, and can be used for follow-on use by other biotech
users. A Leasehold Improvement allowance in the amount not to exceed $100/gsf
will be provided by Genesee Properties to be collected by GA or Genesee
Properties as added rent starting with substantial completion of Leasehold
Improvements, the total amortized at 11% per annum over a seven year period.

The Leasehold allowance can be used for the following:

A.      Design costs, costs expended in preparing leasehold improvement cost
and estimate, document preparation, processing fees, and cost of permits to
install Leasehold Improvements.

B.      Installation of structures, walls, ceilings, doors, and access
openings required to access laboratories and to establish corridors and access
control features to serve the laboratories and supporting administrative space.

C.      Installation of mechanical and plumbing equipment and services to
support laboratories, offices, and service areas. This includes heating, air
conditioning, exhaust systems, distribution of natural gas, compressed air,
deionized water, specialty gases, potable water, standard fire protection
water, industrial water, and sewer. In those cases where services interface
with Alanex fixtures, or equipment, Leasehold Improvements will provide for
specified service installation to a convenient point of connection such as
above ceiling or at rough-in locations as designated on the working drawings
and specifications.

D.      Installation of electrical equipment and services to distribute
commercial and portable power for lab equipment, lighting, telecommunications,
standard data communications, special data communications to serve Building 9
premises, and standard life safety, fire protection, and alarms. In those cases
where services interface directly with Alanex fixtures or equipment, the
Leasehold Improvements will provide for installation of specified services to a
convenient point of connection such as above ceiling; to a junction box or
disconnect device such as a fused switch or quick disconnect; or as designated
on the design drawings.

E.      Installation of exterior windows, interior windows, window treatment,
doors, door hardware, suspended ceiling, electrical trim, mechanical trim, floor
covering and painting.

Once working drawings and specifications are completed:

F.      GA will prepare a project cost estimate (with a 10% contingency) to be
used during bidding and construction of the Leasehold Improvements. This
estimate plus costs of design,

                                                                     ---------
<PAGE>   30
document preparation, permits, fees and other costs (Paragraph II) will
establish baseline cost for planned improvements.

G.      If the total cost, including contingency, exceeds $100/gsf, Alanex will
have the option to pay or finance with other third parties the "excess costs"
or reduce the scope of work to bring costs within the financing budget. If
after reviewing alternatives of reducing cost of the leasehold improvements to
within 110% of the promised financing, Lessee determines that the costs of the
leasehold improvements are beyond its capability to pay, then Lessee has the
option to terminate its agreement to the Lease Building 9 premises on condition
that Lessee notifies the Lessor in writing within thirty (30) days after receipt
of the estimate, and pays for all Lessors costs expended to date, including and
limited to: cost of design, cost for producing documents; permit fees; cost of
preparing the estimate; and payment of the base rent for the Building 9 premises
for the thirty (30) day delay period.

H.      If at any time during the construction of the Leasehold Improvements,
the costs thereof incurred by GA equals the amount of the allowance plus any
already paid "excess costs", General Atomics will immediately prepare an
estimate of the amounts reasonably required to complete the construction and
will request Alanex to deposit funds with General Atomics in the amount of the
estimate.

I.      To control costs and maintain schedule, delays will be minimized. Once
work starts on preparing working drawings and specifications, any delays will
be formalized by notice or weekly progress meeting minutes. These delays may
represent: delay in providing design criteria or other information; delay in
approving design drawings; delays in obtaining permits; delays due to
implementing change orders; delays in delivery of long lead mechanical,
electrical or building materials.

J.      General Atomics will prepare a milestone project schedule to be used by
the project team during design, permitting and construction of the Leasehold
Improvements. Delays in the installation of Alanex fixtures shall not
constitute delays in bringing the installation to substantial completion.

K.      Alanex will determine its preference for contracting the installation
of fixtures and equipment requiring structural, electrical, mechanical or
piping connections. One option is to include part or all of the installation
through contractors engaged by General Atomics to install Leasehold
Improvements. If Alanex elects to use these contractors, General Atomics will
require advanced payment to cover the work authorized through General Atomics
purchase orders. Accounting for the installation of Alanex equipment, fixtures
and personal property will be maintained separate from Genesee Properties
Leasehold Improvement costs.

L.      Upon substantial completion of the Leasehold Improvements (that date
which permitting agencies give their final approval to occupy) a walk-through
inspection will be conducted to develop a punch-list of items needing
correction or additional work.

M.      No later than 60 days after substantial completion of Leasehold
Improvements, Alanex shall provide GA with a final punchlist of any items
requiring correction.

                       III. TENANT FIXTURES AND EQUIPMENT

Alanex will be responsible for the design, purchase, installation, or
relocation of its fixtures, hardware, and personal property to complement the
Leasehold Improvements. Said equipment will remain under Alanex ownership, and
its installation will be the responsibility of Alanex. Alanex will discharge
its responsibilities as follows:

formal policy for storage, dispensing, use and handling of hazardous materials
and flammable gases at the "Industrial Center" in compliance with local codes
that promulgate the requirements of the Uniform Building and Uniform Fire Codes.

                2.  Lenders and insurance carriers have intensified overview
inspections at the "Industrial Center" including the Lessee's premises;
insurance carriers have imposed additional insurance premiums for increased
liability caused by the Lessee's use, and use by others, of the Lessor's
"Industrial Center." Underwriters and consultants have recommended improved
communications between parties hereto as a method for mitigating further 
liability.

                3.  On occasion, certain building systems and utilities have
been modified or altered by individuals or companies that do not possess the
knowledge, qualifications, license and insurance to engage in these services.
Modifications or alterations to building structures, systems or utilities
including fire walls, doors, electrical, plumbing, heating, ventilation and air
conditioning, or other common area utilities, by service companies or
personnel, particularly those not holding a license, having the proper
insurance coverage or possessing adequate training and qualifications, could
cause damage to Lessee's business as well as to that of others.

                4.  Unplanned utility interruptions such as those caused by
abnormal weather conditions, earthquakes, fires, construction mishaps, or
"Industrial Center" plant equipment failures, may result in extended utility
outages that could affect the Lessee's business operations. Restoration of
services through connection to standby equipment such as portable electric
generators, portable air conditioning chillers, or other "Industrial Center"
Systems, could require outages extending beyond a 24-hour period.

                5.  Shared building systems and utilities, including heating
and ventilation, plumbing, electrical and other common utilities, require
day-to-day attention and operations within system design limits. Specifically,
laboratory heating and air conditioning systems are designed for conditioning
of 100% outside air, variable volume supply or for auxiliary supply, whereas
the system serving the combined office and corridor spaces is designed to
circulate space envelope air using at least 20% outside air. The two space
envelopes should therefore be maintained separate to prevent air mixture,
provide isolation for fire protection and to prevent overload of heating and
cooling systems.

NOW, THEREFORE, in consideration of the foregoing, and in consideration of
mutual covenants and agreements of the parties hereto, the parties mutually
covenant and agree as follows:

as follows:

        Payments of principal and accrued interest hereunder shall be due in
three equal annual installments beginning one year from the date hereof with
the principal amount and any unpaid interest due in full on November 22, 1996;
provided, however, that in the event that the undersigned's employment by or

principal and interest shall become due and payable immediately after such
termination. If the undersigned fails to pay any of the principal and accrued
interest when due, the Corporation may deliver a notice requesting payment of
interest within 10 days of receipt thereof; if such payment is not made, the
Corporation, at its sole option, shall have the right to accelerate this Note,
in which event the entire principal balance and all accrued interest shall

        This Note may be prepaid at any time without penalty. All money paid

interest as required hereunder and then to the retirement of the principal.

                                PROMISSORY NOTE

$50,000                      San Diego, California      Dated: November 3, 1995

        FOR VALUE RECEIVED, the undersigned, ALEXANDER POLINSKY an individual,
promises to pay to the order of ALANEX CORPORATION, a California corporation,
at 3550 General Atomics Ct., San Diego, California, the principal sum of Fifty
Thousand Dollars ($50,000). Accrued interest shall be paid annually in three
installments from the date of this note until November 3, 1998 at which time
the entire balance of unpaid principal shall all be due and payable in full,
along with any unpaid interest. Interest is payable at the minimum rate of
interest required to avoid imputed interest. Any installment, when paid, shall
be credited first on interest then due and the remainder on principal, and
interest shall thereupon cease upon the principal so credited.

        Should interest not be paid when due, it shall thereafter bear like
interest as the principal, but such unpaid interest so compounded shall not
exceed an amount equal to simple interest on the unpaid principal at the
maximum rate permitted by law.

        The Borrower hereunder shall have the right, at any time, to prepay all
or any portion of the principal amount of this Note without penalty.

        If default is made in the payment when due of any part or installment
of principal or interest under this Note, then the whole sum of principal then
unpaid, together with accrued interest thereon, shall become immediately due
and payable at the option of the holder of this Note, without notice.

        The provisions hereof shall be binding upon the successors and assigns
of the borrower hereunder, and shall insure to the benefit of the holder of
this Note, and his respective heirs, legal representatives, successors and 
assigns.

        Principal and interest are payable in lawful money of the United States
of America. Should default be made in payment and if action is instituted on
this Note, the undersigned promises to pay such sum as the court may fix as
attorney's fees. This Note shall be governed by and construed in accordance
with the laws of the State of California.

                                PROMISSORY NOTE


$60,000                      San Diego, California           Dated: May 22, 1996


        FOR VALUE RECEIVED, the undersigned, MARVIN R. BROWN an individual,
promises to pay to the order of ALANEX CORPORATION, a California Corporation,
at 3550 General Atomics Ct., San Diego, California, the principal sum of Sixty
Thousand Dollars ($60,000). Interest shall be paid annually in three
installments from the date of this note until May, 1999 at which time the
entire balance of unpaid principal shall be due and payable in full, along with
any unpaid interest. Interest is payable at the minimum rate of interest
required to avoid imputed interest. Any installment, when paid, shall be
credited first on interest then due and the remainder on principal, and
interest shall thereupon cease upon the principal so credited.

        Should interest not be paid when due, it shall thereafter bear like
interest as the principal, but such unpaid interest so compounded shall not
exceed an amount equal to simple interest on the unpaid principal at the
maximum rate allowed by law.

        The borrower hereunder shall have the right, at any time, to repay all
or any portion of the principal amount of this Note without penalty.

        If default be made in the payment when due of any part or installment
of principal or interest under this Note, then the whole sum of principal then
unpaid, together with accrued interest thereon, shall become immediately due
and payable at the option of the holder of this Note, without notice.

        The provisions hereof shall be binding upon the successors and assigns
of the borrower hereunder, and shall insure to the benefit of the holder of
this Note, and his respective heirs, legal representatives, successors and 
assigns.

        Principal and interest are payable in lawful money of the United States
of America. Should default be made in payment and if action is instituted on
this Note, the undersigned promises to pay such sum as the court may fix as
attorney's fees. This Note shall be governed by and construed in accordance
with the laws of the State of California.

Dear Michelle:

Alanex Corporation (the "Company") is pleased to offer you the position of
Director of Finance and Administration on the following terms.

You will be expected to manage the financial, accounting and administrative

the Company. Of course, Alanex may change your position, duties and work
location from time to time as it deems necessary.

You will receive a salary of one hundred eight thousand dollars ($108,000) per

Such salary shall be prorated for any partial year of employment on the basis
of a three hundred sixty-five day (365) fiscal year. Your compensation shall be
subject to customary withholding taxes and any other employment taxes which are
commonly required to be collected or withheld by the Company. You will also be
eligible for a bonus of twenty-two thousand five hundred dollars ($22,500.00)

dollars ($11,250.00) shall be payable within thirty (30) days following the
successful completion of an initial public offering of securities of the
Company; and (2) eleven thousand two hundred fifty dollars ($11,250.00) shall
be paid upon the completion of one year of service with the Company, subject to
your satisfactory performance in that year.

(the fair market value of the company's Common Stock) (the "Option") under the
standard terms of the company's 1993 Stock Option Plan or any successor stock
option plan. The Option shall vest in equal monthly installments over a
four-year period. The Option shall have a term of ten years.

However, with respect to your entitlement to vacation time, you will receive

annually. The company may modify its compensation and benefits from time to
time as it deems necessary.

As an Alanex employee, you will be expected to abide by company rules and
regulations, acknowledge in writing that you have read the company Employee
Handbook, and sign and comply with a Proprietary Information and Inventions

whatsoever simply by notifying the Company. Likewise, the Company may terminate
your employment at any time and for any reason whatsoever, with or without
cause or advance notice. This at-will employment relationship cannot be changed
except in writing signed by a company officer.

Notwithstanding your status as an at-will employee, the Company agrees that if
you are terminated without cause at any time within the first two years of your
employment with the Company, the vesting of your Option shall accelerate by a
period of two years from the date of your termination. If you are terminated
without cause at any time after the first two years of employment with the
Company, the vesting of your Option shall accelerate by a period of one year
from the date of your termination. All shares subject to the Option that do not
vest pursuant to this paragraph shall cease vesting and the Option with respect
to such shares will be canceled.

If your employment under this letter agreement is terminated by the Company for
cause, you shall be entitled to receive only your accrued base salary and other
accrued benefits required by law, prorated to the date of termination. For
purposes of this Agreement, "for cause" termination shall be limited to the
following: (1) engaging or in any way participating in any activity which is
competitive with or intentionally injurious to the Company or which violates
any provisions of the Proprietary Information and Inventions Agreement; (2) the
commission of any fraud against the Company or use or appropriation for your
personal use or benefit any funds or properties of the Company not so
authorized by the Board of Directors; (3) the conviction of a crime involving
dishonesty or moral turpitude; or (4) conduct which in good faith and
reasonable determination of the Board of Directors demonstrates gross unfitness
to serve in your position.

The employment terms in this letter supersede any other agreements or promises
made to you by anyone, whether oral or written. As required by law, this offer
is subject to your satisfactory proof of your right to work in the United

                          TO GENESEE PROPERTIES, INC.
                                October 31, 1994
                             San Diego, California


Name of Borrower:       ALANEX CORPORATION
Maximum Disbursements:  $1,476,640
Interest Rate:          11.0 PERCENT PER ANNUM
Maturity Date:          MAY 1, 2002 


1.      FOR VALUE RECEIVED, the undersigned, Alanex Corporation, a California
corporation ("Borrower"), promises to pay to the order of Genesee Properties,
Inc., a Wyoming corporation ("Holder"), located at 3550 General Atomics Court,
Room 01-141, San Diego, California 92121, amounts of principal equal to the
total aggregate amounts to be disbursed by Holder to General Atomics on behalf
of Borrower for the leasehold improvements to be made by General Atomics to the
Alanex "ADDED" space as that term is defined in the Sublease By and Between
General Atomics and Alanex Corporation dated July 1, 1994 (the "Sublease")
plus the accrued interest for the period March 1, 1995 until May 1, 1995, as
described in paragraph 2 (this principal and interest to be collectively
referred to as the "Debt".) Borrower may, at its election, prior to May 1, 1995
pay the accrued interest for the period March 1, 1995 to May 1, 1995. Effective
May 1, 1995 interest will accrue on the unpaid balance of the Debt at the rate
of 11.0 percent per annum (computed on the basis of a 360 day year). Repayment
of the Debt will be made in eighty-four (84) equal payments of principal and
interest with the first payment due on June 1, 1995 and subsequent payments 
being due on the first day of each month thereafter. The amount of the monthly
payments shall be determined by computing the amount necessary to fully
amortize the Debt as of May 1, 1995 over eight four (84) months with equal
payments of principal and interest. All unpaid Debt and interest outstanding on
May 1, 2002 shall be due and payable on that date.

2.      The maximum total aggregate amount to be disbursed by Holder to General
Atomics pursuant to this Note shall be limited to One Million Four Hundred and
Seventy Six Thousand Six Hundred and Forty Dollars ($1,476,640.) The accrued
interest portion of the Debt, as described in paragraph 1, shall be determined
by calculating the finance costs from March 1, 1995 until May 1, 1995 based on
the total aggregate amounts disbursed by Holder to General Atomics with
interest at the rate of 11% per annum (computed on the basis of a 360 day year)
for the period March 1, 1995 until May 1, 1995.

3.      To secure payment of this Note the undersigned hereby pledges to the
Holder as collateral all rights it now has or may have in the Sublease and any
subsequent amendments including any future amendments. At the request of
Holder, Borrower will join with Holder in executing one or more Financing
Statements recording the Holder's security interest in the Sublease.

Secured Promissory Note to Genesee Properties, Inc. (10/31/94)       Page 1 of 3
  
<PAGE>   2
4.      In case of default in payment of this Note or a default in the Sublease
that is not cured within ten (10) days of written notice and in addition to all
other rights Holder may have under this Note, Borrower, upon written demand by
Holder, shall abandon all rights it has in the Sublease in favor of the Holder,
and the Holder shall acquire all rights which were previously accorded Borrower
under the terms of the Sublease. Notwithstanding any action taken by Holder in
the event of default under this Note or the Sublease, Borrower shall continue
to be obligated to General Atomics under the terms of the Sublease.

5.      Each payment shall be credited first to the interest then due and the
remainder shall be credited to Debt. Interest shall thereupon cease to accrue
upon the Debt so credited.

6.      If Borrower fails to make any payment of Debt or interest when due, or
is in default to General Atomics under the terms of the Sublease, or the
Sublease is terminated for any reason the whole sum of the Debt then unpaid,
together with accrued interest thereon, shall become immediately due and
payable at the option of the Holder of this Note, without notice.

7.      Acceptance by the Holder of any installment after any default hereunder
shall not operate to extend the time of payment of any amount then remaining
unpaid or constitute a waiver of any other rights of the Holder under this Note.

8.      Borrower reserves the right at any time to pay all of the installments
remaining due on this Note with interest to the time of payment, and with no
penalty.

9.      Borrower agrees to pay the actual expenditures reasonably incurred by
Holder in any attempt to collect any amounts due pursuant to this Note.

10.     Borrower agrees that if any legal action is necessary to enforce or
collect this Note, the Holder shall be entitled to reasonable attorneys' fees
in addition to any other relief to which it may be entitled.

IN WITNESS WHEREOF, the undersigned Corporation has caused this note to be
executed by an officer duly authorized to do so.
