PROSPECTUS
   
                              LIDAK PHARMACEUTICALS

                    3,111,748 Shares of Class A Common Stock*

       This Prospectus relates to 3,111,748 shares of Class A Common Stock, no
par value (the "Class A Common Stock") of LIDAK Pharmaceuticals (the "Company")
reserved for issuance upon the exercise of 1,780,021 outstanding Class D
Warrants of the Company (the "Class D Warrants"), 100,000 outstanding Class E
Warrants of the Company (the "Class E Warrants"), and 1,231,727 shares of
outstanding Class A Common Stock which resulted from the conversion of Series B
Preferred and/or exercise of Class D Warrants and Class E Warrants. The Class D
Warrants were originally issued to certain investors in private placements which
occurred in July 1991 and February 1992. The Class E Warrants were originally
issued to Whale Securities Co., L.P., and its designees, as partial
consideration for services as placement agent in the private placement which
occurred in February 1992. The holders of the Class D Warrants and Class E
Warrants and the Class A Common Stock resulting from their exercise are referred
to herein as the "Selling Securityholders." See "Selling Securityholders."

       Each Class D Warrant is exercisable through February 26, 1997 to
purchase, for $1.50, one share of Class A Common Stock. Each Class E Warrant is
exercisable through January 7, 1997 to purchase, for $0.20, one share of Class A
Common Stock. The exercise prices of the Class D Warrants and Class E Warrants
are subject to adjustment under certain circumstances. See "Description of
Securities." (The Class D Warrants and Class E Warrants are referred to herein
collectively as the "Securities.")
    

       The Class A Common Stock issued or issuable upon conversion or exercise
of the Securities may be sold from time to time by the Selling Securityholders
or by their transferees. At the date of this Prospectus, no underwriting
arrangements have been entered into by the Selling Securityholders. The
distribution of the Class A Common Stock by the Selling Securityholders may be
effected in one or more transactions that may take place in the over-the-counter
market, or such other market on which the Company's securities may from time to
time be trading, including ordinary broker's transactions or through sales to
one or more dealers for resale of such shares as principals, at market prices
prevailing at the time of sale or at prices determined in privately negotiated
transactions. Usual and customary or specifically negotiated brokerage fees or
commissions may be paid by the Selling Securityholders in connection with such
sales of Class A Common Stock. See "Description of Securities" and "Plan of
Distribution."

   
       The Selling Securityholders and intermediaries through whom such
securities are sold may be deemed "underwriters" within the meaning of the
Securities Act of 1933, as amended (the "Act"), with respect to the securities
offered, and any profits realized or commissions received may be deemed
underwriting compensation. The Company will not receive any of the proceeds from
the sale of Class A Common Stock by the Selling Securityholders. Cumulative
expenses of this offering, estimated at $155,000 are payable by the Company. In
the event Class D Warrants or Class E Warrants are exercised, the Company will
receive cash in the amount of the exercise price. See "Description of
Securities" and "Selling Securityholders."

       covered in this Post-Effective Amendment represent the number of

       and warrants have been disposed of by the Selling Shareholders prior to
       the date of the Prospectus.

                                   THE COMPANY

   
   LIDAK Pharmaceuticals ("LIDAK" or the "Company") is a development stage
company organized to engage in research, development and commercialization of
innovative pharmaceutical products. The Company was incorporated in California
in 1988 and since inception has operated in one business segment -- research and
development of pharmaceutical products. The Company is currently focusing on the
development and commercialization of 1) its patented therapeutic product
n-docosanol 10% cream (LIDAKOL(TM)), as a topical treatment for oral herpes
(cold sores or fever blisters), and 2) its patented Large Multivalent Immunogen
("LMI") technology as a potential immunotherapeutic vaccine treatment of
malignant melanoma and other human cancers.

   During fiscal 1995, a Phase 3 clinical trial of LIDAKOL as a topical
treatment for oral herpes was completed in Europe by the Company's European
licensing partner, Yamanouchi Europe. Three additional Phase 3 clinical trials
of LIDAKOL for the same indication conducted by the Company in the U.S. and
Canada have been recently completed and results of these trials are expected in
the first calendar quarter of 1996.
    

   To date, the Company has entered into four licensing agreements relating to
the marketing of LIDAKOL. In November 1991, the Company entered into an
agreement with Yamanouchi Europe, b.v., formerly Brocades-Pharma, b.v. of the
Netherlands ("Yamanouchi"), under which Yamanouchi received rights to market
certain topical indications of LIDAKOL in certain European and other countries.
In July 1993, the Company entered into a licensing agreement with CTS Chemical
Industries, Ltd. ("CTS"), a subsidiary of CTS, Ltd., located in Kiryat Malachi,
Israel, under which CTS received rights to market certain topical indications of
LIDAKOL in Israel. In July 1994, the Company entered into an agreement with
Boryung Pharmaceuticals Company, Ltd. ("Boryung"), located in Seoul, Korea,
under which Boryung received the rights to market certain topical indications of
LIDAKOL in the Republic of Korea. In October 1994, the Company entered into an
agreement with Grelan Pharmaceutical Co., Ltd. ("Grelan"), located in Tokyo,
Japan, under which Grelan received rights to market certain indications of
LIDAKOL in Japan. In each of the territories covered by the above agreements, as
well as in the United States and other territories not covered by these
agreements, marketing of LIDAKOL is subject to obtaining appropriate government
approvals. The Company is currently seeking to enter into licensing and/or other
collaborative arrangements with respect to LIDAKOL in the United States and
other territories not covered by the above agreements.

   
   The Company's second current area of focus is the development of new
therapeutic approaches to cancer and viral infections using the LMI technology.
This technology involves the use of antigen-containing artificial cell membranes
to stimulate the immune system's defense against cancer and viral diseases. In
December 1995, the Company initiated a Phase 1/Phase 2 clinical trial of LMI in
patients with malignant melanoma pursuant to an Investigational New Drug
Application ("IND") approved by the United States Food and Drug Administration
("FDA"). The Company's rights to the LMI technology, and certain other
technologies, derive from a licensing agreement with Medical Biology Institute
("MBI"), a non-profit research organization founded in 1981 by Dr. David H.
Katz, the founder, President and Chief Executive Officer of the Company.

   The Company has experienced significant losses since inception and its
business is subject to significant risks. The Company does not expect LIDAKOL,
LMI or any other of its proposed products to be available for commercial sale
for several years, if at all. Assuming that the Company is successful in
obtaining applicable regulatory approvals, it will still be necessary to enter
into additional licensing or
    

                                               
                                      - 7 -
<PAGE>   11
   
other collaborative arrangements with pharmaceutical or biotechnology companies
which have sufficient financing and personnel resources and/or to raise
substantial additional financing and hire appropriate personnel in order for the
Company to successfully commercialize LIDAKOL for oral herpes in the United
States. In order for the Company to successfully commercialize other indications
of LIDAKOL, LMI, or any other technologies, it will be necessary to enter into
additional licensing or other collaborative arrangements with pharmaceutical or
biotechnology companies which will bear the cost of completing the remaining
non-clinical development, the required clinical trails and regulatory approval
process and marketing of such products, if approved, and/or to raise substantial
additional financing and hire appropriate personnel.

   There can be no assurance that the results from the Phase 3 clinical trials
of LIDAKOL in the U.S. and Canada or future clinical trials of LMI will
demonstrate satisfactory efficacy and safety to support the filing of New Drug
Applications ("NDA") with the FDA or other marketing approval applications with
regulatory agencies outside the U.S., that the FDA and/or other regulatory
agencies outside the U.S. will not require the Company to perform additional
clinical trials or that the FDA and/or other regulatory agencies outside the
U.S. will ultimately grant marketing approval for these products. There can be
no assurance that additional non-clinical and clinical testing will demonstrate
that the Company's other technologies will meet the safety and efficacy
requirements to complete development and obtain appropriate regulatory marketing
approvals. Furthermore, there can be no assurance that the Company will be able
to raise sufficient additional capital to complete development efforts and
commercialize any of its proposed products or that additional licensing
arrangements can be established on terms favorable to the Company, or at all.

   The Company was incorporated in California on August 31, 1988. The Company's
executive offices are located at 11077 North Torrey Pines Road, La Jolla,
California 92037 and its telephone number is (619) 558-0364. See "Risk
Factors--Relationship with and Dependence on Medical Biology Institute."
    


                                  RISK FACTORS

   The purchase of the securities offered hereby involves a high degree of risk
including, but not necessarily limited to, the risk factors described below.
Prospective investors should carefully review and consider the following risks
as well as the other information provided in this Prospectus.

   
   1.  Development Stage Company; Explanatory Paragraph in Independent Auditors'
Report for the Fiscal Year Ended September 30, 1995; History of and Continuing
Losses.  The Company's independent auditors have included an explanatory
paragraph in their report issued in connection with their audit of the Company's
financial statements as of and for the fiscal year ended September 30, 1995 that
refers to the Company's activities as those of a development stage enterprise.
Through September 30, 1995 the Company has generated only limited revenues.
Primarily as a result of expenses incurred in organizational and research and
development activities, the Company has incurred net losses aggregating
approximately $28.2 million from its inception through September 30, 1995. Since
September 30, 1995 the Company has incurred operating losses, and anticipates
that it will continue to incur substantial operating losses until such time, if
ever, that the Company achieves significant revenue from its products. Potential
investors should be aware of the problems, delays, expense and difficulties
encountered by any company in the developmental stage, many of which may be
beyond the Company's control. These include, but are not limited to,
unanticipated problems relating to product development and formulation, clinical
testing, regulatory compliance, production and marketing, additional costs and
competition. There can be no
    
                                                 
                                      - 8 -
<PAGE>   12
assurance that the Company's proposed products, if fully developed and if
required regulatory approvals are obtained, can be successfully marketed or that
the Company will ever achieve significant revenues or profitable operations.

   
   2.  Significant Capital Requirements; Need for Working Capital and Additional
Financing.  The commercialization of LIDAKOL or any of the Company's other
products will require capital reserves substantially greater than those
currently available to the Company. Accordingly, the Company will be required to
raise additional capital and/or to collaborate with one or more large
pharmaceutical companies which will provide the necessary financing and
expertise to obtain regulatory approvals, complete clinical development,
manufacture and market LIDAKOL or any other products for sale in the United
States and certain other foreign countries. To date, the Company has entered
into four such agreements relating to LIDAKOL for herpes. There can be no
assurance that the Company will be able to raise additional capital or to enter
into other collaborative arrangements necessary to further develop or
commercialize LIDAKOL or any of its other proposed products on acceptable terms.
Failure to obtain required additional financing, or to enter into additional
collaborative and licensing arrangements for the continued development,
manufacturing, marketing and distribution of the Company's products, would
materially limit the Company's ability to finance or undertake its proposed
operations. In such event, if the Company were unable to obtain from alternate
sources the substantial financing necessary on acceptable terms, it would be
unable to commercialize any products.

       In addition, the Company is obligated to repay $13,500,000 of Convertible
Notes (the "Notes") in late 1997 and early 1998 to the extent the Notes are not
previously converted. There can be no assurance that the Company will have
sufficient capital resources on hand or, if not, that it will be able to
successfully raise the additional capital required to repay the Notes.
Furthermore, the Notes are convertible into a maximum of 5,513,018 shares of the
Company's Common Stock, with each Note limited to a pro-rata amount of such
number of shares. In the event that shares of Class A Common Stock underlying a
particular Note cannot be issued upon request for conversion due to the above
referenced maximum share limitation, the Company is immediately obligated to
repay the principal of that portion of the Note which is presented for
conversion and cannot be converted plus a premium equal to 25% of such principal
plus any accrued and unpaid interest. See "Description of Securities-Convertible
Notes Due 1997 and 1998," below. In such event, depending upon the dollar amount
of the repayment obligation, the Company's working capital might be
substantially reduced, which could occur at a time when it would be difficult
for the Company to raise additional capital. Should that occur it would also
likely have a material adverse effect on the Company.

   3.  Early Stage of Research Development; Unproven Products; Possible Loss of
Product Development Costs.  The Company does not expect LIDAKOL for oral herpes
to be available for commercial sale or use in the United States and certain
foreign markets for several years, if at all. There can be no assurance that
LIDAKOL or any of the Company's other proposed products will be successfully
developed, proved to be safe and efficacious in clinical trials, prove to be
more effective than formulated products based on existing or newly developed
technologies, meet applicable regulatory standards, demonstrate substantial
therapeutic benefits in the treatment of any disease, be capable of being
produced in commercial quantities at reasonable costs or be successfully
marketed. There can be no assurance that effectiveness of these technologies in
pre-clinical studies performed in vitro or in animal models will be pertinent to
the development of, or indicative of the efficacy of, a product for human use.
The continued development of the Company's products, including LIDAKOL, remain
subject to all the risks inherent in the development of products based on
innovative technologies, including unanticipated development problems and the
possible insufficiency of funds which could result in the abandonment or
substantial
    

                                      - 9 -
<PAGE>   13
   
change in the development of a specific product. The development of medical
products is a lengthy and capital intensive process. The risk of failure to
complete development of the Company's proposed products is substantial.
Unsuccessful Phase 3 clinical trial results for proposed products or the
inability to successfully complete development, or a determination by the
Company, for economic or other reasons, not to undertake to complete development
of a particular product, could have a material adverse effect on the Company.
Such a material adverse effect with respect to unsuccessful clinical trial
results for LIDAKOL for oral herpes would be virtually assured.

   4.  Uncertainty of Market Acceptance; Limited Marketing Arrangements for
Proposed Products.  Except for its arrangement with Molecular Probes, Inc. (See
"Business--Research and Development; Free Fatty Acids") the Company has not
commenced marketing of any products to date and, at the present time, has
limited marketing capabilities. Achieving market acceptance will require
substantial marketing efforts and the expenditure of significant funds to inform
potential consumers of the perceived benefits of the Company's proposed
products. The Company has no experience in the marketing or distribution of its
proposed products. Moreover, the Company does not have the financial and other
resources to undertake extensive marketing and advertising activities.
Accordingly, the Company intends generally to rely on marketing arrangements,
including possible joint ventures, license or distribution arrangements with
third parties. To date, the Company has entered into agreements with Yamanouchi,
CTS, Boryung, Grelan and Molecular Probes, Inc. There can be no assurance that
it will be successful in entering into similar agreements with other parties in
the future or that its products can be successfully marketed.

   5.  Government Regulation.  The development, production, testing,
manufacturing and marketing of pharmaceutical products is subject to significant
regulation by governmental authorities in the United States and other countries.
The clinical testing and regulatory approval process can take a number of years
and require the expenditure of substantial resources. There can be no assurance
that regulatory approval will be obtained for any of the Company's proposed
products. A significant portion of the proceeds of the Company's financings are
being used for research and development and clinical trials necessary for
seeking such approvals for the Company's products. There can be no assurance
that the Company will be able to enter into additional collaborative
arrangements with large pharmaceutical companies to provide the financing
necessary to complete the required testing and regulatory review process for the
Company's products. Further, the expenditures by the Company will be made
without any assurance that approvals will be obtained and before it can be
ascertained whether the Company's products can be commercialized. The inability
to obtain, or delays in obtaining, such approval would adversely affect the
Company's ability to commence marketing such products and could have a material
adverse effect on the Company. The Company is unable to predict the extent of
adverse governmental regulation which might arise from future United States or
foreign legislative or administrative action.

       Moreover, the Company cannot predict with accuracy the effect of
unspecified, but possible, future changes in the regulatory approval process and
in the domestic health care system. Possible future changes could affect the
time frame required for regulatory review and the sale prices of the Company's
products, if approved for sale.

   6.  Technological Change and Competition.  The pharmaceutical industry is
subject to rapid, unpredictable and significant technological change.
Competition from universities, research institutions and pharmaceutical,
chemical and bio-engineering companies may be intense. There can be no assurance
that developments by the Company's competitors or potential competitors will not
render the Company's proposed products obsolete. Most of such competitors or
potential competitors have greater financial resources, research and development
facilities and manufacturing and marketing experience than the
    

                                     - 10 -
<PAGE>   14
   
Company. If the Company's first proposed product, LIDAKOL, is successfully
developed, it will compete with other prescription anti-viral products used to
treat herpes currently on the market in the United States and other
over-the-counter preparations, as well as other products or potential products
which are or may be under development or undergoing the FDA regulatory approval
process. See "Business--Competition."

   7.  Relationship With and Dependence on Medical Biology Institute.  With the
exception of LIDAKOL, the Company's technologies have been obtained by license
from Medical Biology Institute ("MBI"), a nonprofit research organization
founded by Dr. Katz and principally funded by research grants awarded by the
National Institutes of Health. Dr. Katz serves as President and Chief Executive
Officer of MBI. Under this licensing agreement (the "MBI Agreement"), the
Company was granted a twenty-year exclusive worldwide license to all technology
and know-how which MBI developed or had under development as of October 10,
1988, the date of the MBI Agreement, and a right of first preference to license
future technology subject to restrictions, if any, in the funding agreements by
which MBI develops the technology. In consideration of these rights, MBI
received 2,000,000 shares of the Company's nonvoting Series A Preferred Stock,
licensing fees in the amount of $900,000, 10 percent of all net license fees
obtained by the Company based on licensed technology, 20 percent of all
royalties paid to the Company by any sublicensee and 6 percent royalties (for
patented inventions) or 3 percent royalties (for nonpatented inventions) on net
sales of products based on licensed technology manufactured and marketed
directly by the Company or any of its subsidiaries. In addition, if the Company
failed to market on a production scale at least one product derived from a
licensed technology or pay a royalty of at least $100,000 per year for the
calendar year ending December 31, 1995, or any calendar year thereafter, MBI had
the right to convert the license to a nonexclusive license upon six months'
notice. MBI may terminate the MBI Agreement upon 180 days' notice in the event
of a default thereunder by the Company which remains uncured for 90 days.
    

       In July 1993, the MBI Agreement was amended, and pursuant to the terms of
the amendment, the Company issued 1,500,000 shares of Class A Common Stock to
MBI in consideration for a 5-year extension of their exclusive technology rights
(until October 10, 2013) and a 5-year postponement (until December 31, 2000) of
the Company's obligation to pay minimum royalties to MBI. The shares granted to
MBI pursuant to the amendment are restricted stock under the federal securities
laws and do not enjoy any registration rights. Additionally, in connection with
the issuance of the new shares, MBI waived all rights to 1,500,000 of its Series
A Preferred Shares which were then held in escrow.

       In July 1994 the MBI Agreement was further amended to provide for future
research funding and support for projects outside the realm of the initial
license agreement. This amendment provides for the transfer of ownership rights
for each specific project during the time it is being funded by the Company.

       There can be no assurance that the Company will have the ability to
satisfy all of its obligations under the MBI Agreement, that the MBI Agreement
will result in the development of any additional products or technologies, that
the Company will be able to maintain its exclusivity to MBI technology, that MBI
will be able to continue to receive adequate research funding, or that MBI will
be able to attract and/or maintain qualified scientific or administrative
personnel. Modification or termination of the MBI Agreement could have a
material adverse effect on the Company.

   8.  Dependence Upon Key Personnel.  The Company is dependent on its executive
management and scientific staff, particularly Dr. David H. Katz, its President
and Chief Executive Officer. Dr. Katz also serves as President, Chief Executive
Officer and a Director of MBI and devotes a portion of his time to MBI. A
reduction in the amount of time Dr. Katz or other key personnel devote to the
Company or the

                                     - 11 -
<PAGE>   15
   
loss of any key person could have a material adverse effect upon the Company's
business. The Company has entered into an employment agreement with Dr. Katz and
has obtained "key-man" life insurance on the life of Dr. Katz in the amount of
$1,000,000. In addition, in order to carry out its business plan, the Company
will be required to retain additional qualified scientific, technical and
administrative personnel. There can be no assurance that the Company will be
able to attract or maintain such additional personnel.

   9.  Patents and Proprietary Rights.  The Company owns five United States and
two European patents, has additional U.S. and foreign patent applications
relating to the topical and systemic uses of LIDAKOL and has been granted rights
under certain United States and foreign patents and patent applications relating
to ophthalmic uses of LIDAKOL held by a third party. In addition, the Company
has been granted rights to certain United States and foreign patents and patent
applications related to LMI and other technologies pursuant to the MBI
Agreement. There can be no assurance that the claims in the pending patent
applications will issue as patents, that any issued patents will provide the
Company with significant competitive advantages, or that challenges will not be
instituted against the validity or enforceability of any patent owned by the
Company or, if instituted, that such challenges will not be successful. The cost
of litigation to uphold the validity and prevent infringement of a patent would
be substantial. Furthermore, there can be no assurance that others will not
independently develop similar technologies or duplicate the Company's
technologies or design around the patented aspects of the Company's
technologies. There is no assurance the Company's proposed technologies will not
infringe patents or other rights owned by others, licenses to which may not be
available to the Company. Finally, federal NIH regulations provide that if
federally-funded institutions do not timely pursue patent applications for
patentable inventions, the government can exercise its right to own such
inventions. This right is in addition to the government's right to use the
results of government sponsored research for specified purposes. Accordingly,
the Company must monitor MBI's filing of patent applications in order to protect
the value of its license agreement with MBI. The MBI Agreement requires the
Company to pay the costs of pursuing and obtaining patents on the licensed
technology and any improvements thereto.
    

       In some cases, the Company may rely on trade secrets and confidentiality
agreements to protect its innovations. There can be no assurance that trade
secrets will be established, that secrecy obligations will be honored or that
others will not independently develop similar or superior technology. To the
extent that consultants, key employees or other third parties apply
technological information independently developed by them or by others to
Company projects, disputes may arise as to the proprietary rights to such
information which may not be resolved in favor of the Company.

   
   10. Dependence Upon a Limited Number of Proposed Products.  The Company's
principal efforts to date have been devoted to the development of LIDAKOL and
LMI technologies. Of these products and technologies, the Company believes that
LIDAKOL is the product most likely to be first available for commercial
distribution; however, the Company does not expect LIDAKOL to be available for
commercial sale or use in the United States and certain foreign markets for
several years, if at all. Accordingly, it is not anticipated that the Company
will generate any significant revenues from sales for several years.
    

   The failure of these products to achieve commercial viability would have a
material adverse effect upon the business and financial condition of the 
Company.

   
   11. Potential Conflicts of Interest.  The Company's President and Chief
Executive Officer is also employed by MBI and serves on the board of directors
of MBI. Other than LIDAKOL, it is hoped that a large part of the Company's
business activities will relate to development of technologies licensed from
    

                                     - 12 -
<PAGE>   16
   
MBI. However, conflicts could arise with respect to, among other things, the
funding for development of licensed projects between the Company and MBI, as
well as the terms of licenses to future developments at MBI pursuant to the
Company's right of first preference to such developments. Although the decisions
with respect to such matters must be approved by a majority of the members of
the Board of Directors not employed by MBI, there can be no assurance that
effective transactions between the Company and MBI will be advantageous to the
Company, that conflicts of interest will not arise with respect to such
transactions or that, if conflicts of interest do arise, they will be resolved
in a manner favorable to the Company.

   12. Control by Insiders.  As of December 31, 1995, the officers and directors
of the Company own approximately 4.38% of the outstanding capital stock of the
Company and possess approximately 7.16% of the voting power. The officers and
directors of the Company may be able, as a practical matter, to influence
considerably the election of directors and thereby select the management and
direct the policies of the Company. At such date, the officers and directors of
the Company also held options and warrants to purchase an additional 3,718,006
shares of Class A Common Stock and 407,000 shares of Class B Common Stock.

   13. Dependence Upon Third-Party Arrangements.  The Company does not have and
does not expect to have in the foreseeable future the resources to manufacture
or directly market on a large commercial scale LIDAKOL or any other products
which it may develop. To successfully commercialize LIDAKOL or any other
products it will be necessary for the Company to enter into collaborative
arrangements with pharmaceutical or biotechnology companies to assist in funding
development costs, including the costs of clinical testing necessary to obtain
regulatory approvals, and costs of manufacturing and marketing. The Company
believes that these arrangements will be more effective in promoting and
distributing its products in view of the Company's limited resources and the
extensive marketing networks and large promotional and advertising budgets of
established pharmaceutical companies. The Company has entered into several
licensing agreements which cover the clinical development, manufacturing and
marketing of LIDAKOL. There can be no assurance, however, that the Company will
be able to finalize any licensing or distributorship arrangements for the United
States and other territories not covered by existing agreements on favorable
terms or at all. The Company may ultimately determine to establish its own
manufacturing and/or marketing capability, at least for certain products, in
which case it will require substantial additional funds and personnel.

   14. Risks Related to Foreign Sales.  The Company is subject to various risks
inherent in foreign trade in connection with the continued development of
LIDAKOL by foreign licensees, and the manufacture, marketing and distribution of
LIDAKOL, if ever, overseas by foreign licensees. Such risks could include
economic or political instability, shipping delays, fluctuations in foreign
currency exchange rates, customs duties and export quotas and other trade
restrictions, all of which could have a significant impact on the Company's
ability to deliver its products.
    

   15. Possible Volatility of Stock Price.  Recent history relating to the 
market prices of the shares of biotechnology companies in general, and the
historical fluctuations in the market price of the Company's Class A Common
Stock, indicates that following this offering the market price of the Company's
Class A Common Stock may be highly volatile. Factors such as fluctuations in the
Company's operating results, developments relating to the progress of clinical
trials for the Company's products and the Company's relationships with present
and potential licensees and distributors, announcements of technological
innovations or new products by the Company or its competitors, and changes in
market conditions and in the economy generally, may have a significant impact in
the market price of the Company's Class A

                                     - 13 -
<PAGE>   17
Common Stock. Further, the market price for the securities of many biotechnology
companies have experienced wide fluctuations which were not necessarily related
to the operating performance of such companies.

   
   16. Dilution.  Purchasers of the shares of the Common Stock offered hereby
will experience immediate and substantial dilution in the net tangible book
value of their shares of approximately $4.77 per share or 93% based on the last
reported sales price of the Company's Common Stock on January 12, 1996.

   17. Product Liability; Absence of Insurance Coverage.  The testing, marketing
and sale of pharmaceutical products entails a risk of product liability claims
by consumers and others. Claims may be asserted against the Company by end users
of any of the Company's proposed products which may be developed. The Company
has obtained product liability insurance coverage for its clinical trials in the
amount of $2,000,000 per incident, and aggregate, and although the Company will
attempt to obtain additional product liability insurance prior to the marketing
of any of its proposed products, there is no assurance that the Company will be
able to obtain such insurance or, if obtained, that such insurance can be
acquired at a reasonable cost or will be sufficient to cover all possible
liabilities. In the event of a successful suit against the Company, lack or
insufficiency of insurance coverage could have a material adverse effect on the
Company. Further, certain distributors of pharmaceutical products require
minimum product liability insurance coverage as a condition precedent to
purchasing or accepting products for distribution. Failure to satisfy such
insurance requirements could impede the ability of the Company to achieve broad
distribution of its proposed products, which would have a material adverse
effect upon the business and financial condition of the Company.

   18. Future Sales of Common Stock.  All of the Company's shares of Class B
Common Stock currently outstanding are "restricted securities" as that term is
defined in Rule 144 promulgated under the Securities Act of 1933, as amended,
(the "Act") and under certain circumstances may be sold without registration
pursuant to such Rule. The outstanding shares of Class B Common Stock, which
will convert into Class A Common Stock upon certain sales or transfers, are
eligible for sale under Rule 144. Additionally, 1,386,800 shares of Class A
Common Stock, outstanding as of December 31, 1995, which were issued to MBI in
July 1993 are also "restricted securities" as defined in Rule 144 of the Act and
under certain circumstances are also eligible for sale without registration
under such Rule. Finally, up to 5,513,018 shares of Class A Common Stock are
potentially issuable upon conversion of the Notes. (See "Description of
Securities - Convertible Notes Due 1997 and 1998"). The Company is unable to
predict the effect that sales of the above-mentioned securities made under Rule
144, or otherwise, may have on the then prevailing market price of the Class A
Common Stock although any substantial sale of such securities may have an
adverse effect.

   19. Effect of Outstanding Convertible Stock, Option and Warrants. As of
December 31, 1995, exclusive of the Shares registered herein, there are
outstanding stock options, to purchase an aggregate of 4,972,196 shares of Class
A Common Stock, which have exercise prices ranging between $0.9375 to $6.75 per
share, and 437,000 shares of Class B Common Stock which have exercise prices
ranging between $0.0125 to $.50 per share. In addition, the Company had
outstanding 283,000 shares of Class B Common Stock at that date, each share of
which is convertible into one share of Class A Common Stock. In addition, the
Company had outstanding at December 31, 1995, Class D and E Warrants which have
exercise prices ranging from $0.20 - $1.50, which, if exercised, would result in
the issuance of 1,880,021 shares of Class A Common Stock. Finally, up to
5,513,018 shares of Class A Common Stock are
    

                                     - 14 -
<PAGE>   18
   
potentially issuable upon conversion of $13,500,000 of principal amount of
currently outstanding Convertible Notes. (See "Description of Securities -
Convertible Notes Due 1997 and 1998").

       To the extent that these outstanding securities are exercised or
converted, dilution of the percentage ownership of the Company's Shareholders
will occur. See "Dilution." Sales in the public market of the Class A Common
Stock underlying options, warrants and the Notes may adversely affect prevailing
market prices for the Class A Common Stock. This, in turn, might adversely
affect the terms upon which the Company will be able to obtain additional equity
capital.
    

   20. Dividends Unlikely.  The Company does not intend to declare or pay cash
dividends in the foreseeable future. Earnings are expected to be retained to
finance its business.

   
   21. Lack of Trading Market in Certain Jurisdictions.  Although securities of
the Company have been qualified for sale only in certain jurisdictions, the
Company's Listed Securities are exempted from the qualification requirements for
offers in the secondary market of most states because of their listing on the
NMS/NASDAQ. However, the Company has not qualified the secondary offering of its
securities in the states of Hawaii and Nebraska and NMS/NASDAQ exemption is not
available in Hawaii. Consequently, the secondary trading of securities of the
Company (including the shares of Class A Common Stock offered by this
Prospectus) in Hawaii and Nebraska can only be conducted through unsolicited buy
and sell orders, privately negotiated transactions, or through other exempt
transactions. Similar restrictions may apply in other jurisdictions.

<PAGE>   19
                                 USE OF PROCEEDS

   
The Company will not receive any of the proceeds from the sale of the Securities
by the Selling Securityholders. The Company will, however, receive gross
proceeds of $2,690,032 in the event of the exercise of all Class D Warrants and
Class E Warrants held by the Selling Shareholders. There can be no assurance
that all or any portion of such securities will be exercised at any particular
time, if ever. It is likely that the Selling Securityholders will not exercise
their securities unless and until the market price of the Class A Common Stock
is significantly greater than the exercise prices of their securities for an
extended period of time. See "Selling Securityholders" and "Description of
Securities."
    

The use to which the Company would put proceeds received upon the exercise of
the Class D Warrants and Class E Warrants offered by this prospectus after the
payment of expenses, will depend upon the amount of proceeds received at any
given time, the then current cash balance of the Company and the then current
funding priorities of the Company. As of the date of this Prospectus, if all of
such securities were exercised concurrently the Company expects that, after the
payment of expenses, it would apply all of the net proceeds to working capital.

                                 DIVIDEND POLICY

   The Company has never paid a cash dividend and does not anticipate the
payment of cash dividends in the foreseeable future as earnings, if any, are
expected to be retained to finance the Company's operations. Declaration of
dividends in the future will remain within the discretion of the Company's Board
of Directors, which may review its dividend policy from time to time.

                            PRICE RANGE OF SECURITIES

   
   The Company's shares of Class A Common Stock have traded on the NASDAQ
National Market System under the symbol LDAKA since September 30, 1993. Previous
to this date, these securities were traded on the NASDAQ Small-Cap Market since
May 8, 1990. The prices set forth below represent quotes between dealers and do
not include commissions, mark-ups or mark-downs, and may not necessarily
represent actual transactions.

                                    DILUTION

   
       As of September 30, 1995, the pro forma net tangible book value of the
Company's common stock was approximately $10,309,716 or $0.36 per share of
common stock. Pro forma net tangible book value per share represents the amount
of total tangible assets of the Company adjusted to give effect to the proceeds
that would be received in the event of exercise of the Class D Warrants and
Class E Warrants registered herein, reduced by the total liabilities and divided
by the number of shares of common stock outstanding after giving effect to the
exercise of the Class D Warrants and Class E Warrants, subject to this
registration, for shares of Class A Common Stock. No additional shares of common
stock will be issued, nor will any proceeds be received by the Company, as a
result of the sale by the Selling Securityholders of the Securities offered by
this Prospectus. See "Use of Proceeds" and "Selling Securityholders." Therefore,
the pro forma net tangible book value at September 30, 1995, after the
distribution of all shares of Class A Common Stock offered hereby, will remain
$0.36 per share of common stock. Assuming a price to the public of $5.13 per
share (based upon the last reported sales price of the Class A Common Stock on
NASDAQ at January 12, 1996), there will be an immediate dilution per share of
$4.77 to new investors purchasing the shares of Class A Common Stock offered
hereby. The dilution to be experienced by new investors will be the same
regardless of the number of Securities sold because the Company would receive no
consideration for the sale.

       The following table illustrates the dilution per share as described
above:

</TABLE>


       At December 31, 1995, the Company also had outstanding options to
purchase an aggregate of 4,972,196 shares of Class A Common Stock at exercise
prices ranging between $0.9375 and $6.75 per share, and 437,000 shares of Class
B Common Stock, at exercise prices ranging between $0.0125 and $0.50 per share.
To the extent such options are exercised and shares of Class B Common are
converted, there will be further dilution to the purchasers of the Class A
Common Stock offered hereby from the public offering price. Finally, up to
5,513,018 shares of Class A Common Stock are potentially issuable upon
conversion of $13,500,000 of principal amount of currently outstanding
Convertible Notes due 1997 and 1998. (See "Description of Securities -
Convertible Notes Due 1997 and 1998").

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

   
       The Company is a development stage company. Since inception in August
1988, the Company has been engaged primarily in research and development
activities. The Company is currently focusing its efforts primarily on the
commercialization of n-docosanol 10% cream (LIDAKOL TM) and its Large
Multivalent Immunogen (LMI) technology. The Company has not generated any
significant product revenues and has been unprofitable since inception. For the
period from inception to September 30, 1995, the Company incurred a cumulative
net loss of $28.2 million. The Company's research and development, clinical
trial and general and administrative expenses will continue to be substantial
and the Company expects to continue to incur operating losses during the next
several years.

       The Company's business is subject to significant risks including, but not
limited to, the success of its research and development efforts, uncertainties
associated with obtaining and enforcing patents important to the Company's
business and lengthy and expensive regulatory approval processes and competition
from pharmaceutical and biotechnology companies, increasing pressure on
pharmaceutical pricing from payors, patients, and government agencies and
limitations on the availability of capital. Even if the Company's products
appear promising at an early stage of development, they may not reach the market
for a number of reasons. Such reasons include, but are not limited to, the
possibilities that the potential products will be found ineffective or toxic
during clinical trials, fail to receive the necessary regulatory approvals, be
difficult to manufacture on a large scale, be uneconomical to market, or be
precluded from commercialization by proprietary rights of third parties, or that
the Company may not have sufficient financial resources. Additional expenses,
delays and losses of opportunities that may arise out of these and other risks
could have a material adverse effect on the Company's financial condition and
results of operations.

RESULTS OF OPERATIONS

COMPARISON OF FISCAL 1994 AND 1995

       Revenues totaled $885,000 for the fiscal year ended September 30, 1995
("fiscal 1995") as compared to $1.0 million for the fiscal year ended September
30, 1994 ("fiscal 1994"). The entire amount of fiscal 1995 revenue is
attributable to interest and other income representing an increase of $402,000
over the fiscal 1994 amount. No revenue was earned during fiscal 1995 from
contract research and federal grant revenue as compared to an aggregate of
$534,000 from these categories in fiscal 1994. The increase in interest and
other income during fiscal 1995 is attributable primarily to higher average cash
balances available for investment and higher interest rates during the year. See
"Liquidity and Capital Resources." The decrease in contract research and federal
grant revenue during fiscal 1995 is due to the completion of all such agreements
prior to the beginning of fiscal 1995.

       Research and development expenses increased by $4.6 million to $7.7
million during fiscal 1995 as compared to fiscal 1994. This increase is
attributable primarily to expenditures associated with the Phase 3 clinical
trials in the United States and Canada, the non-clinical toxicology program for
LIDAKOL for the topical treatment of oral herpes which began in fiscal 1995, and
the continued preclinical development of LMI.

       General and administrative expenses increased to $3.3 million during
fiscal 1995 from $2.6 million in fiscal 1994. The increase in current year
expenses is attributable primarily to the one-time payment of fees in
    

                                     - 21 -
<PAGE>   25
   
connection with the completion of a two-year consulting agreement in February
1995, and investment banking fees associated with the Company's license
agreement with Grelan Pharmaceutical Co., Ltd. of Japan. General and
administrative expenses also increased during the year due to personnel costs
related to staff additions, market research expenditures, and occupancy costs
related to an expansion of office space. In addition, consulting, legal and
other costs increased as a consequence of a proposed acquisition during the
year.

       Contract research expenses decreased during fiscal 1995 by $155,000 as
compared to fiscal 1994 as a direct result of decreased contract research
revenue as noted above.

       As a result of the foregoing revenues and expenses, the Company's net
loss increased to $10.2 million during fiscal 1995 from $4.8 million in fiscal
1994.

COMPARISON OF FISCAL 1993 AND 1994

       Revenues increased by $426,000 to $1.0 million for the fiscal year ended
September 30, 1994 ("fiscal 1994") as compared to the fiscal year ended
September 30, 1993 ("fiscal 1993"). The increase in revenues in fiscal 1994 is
attributable primarily to an increase in contract research activity involving
the Company's hu-PBL-SCID mouse technology. As a result of this activity,
contract research revenues increased $320,000 as compared to fiscal 1993. The
Company does not expect that future revenues from contract research activity
involving the hu-PBL-SCID mouse technology will be significant. Interest and
other income increased $153,000 primarily as a result of higher interest rates
and a higher cash balance available for investment due to proceeds received from
the exercise of warrants during fiscal 1994. See "Liquidity and Capital
Resources." Partially offsetting these increases was a decrease in federal
research grant revenue of $48,000 during fiscal 1994 as a result of the
completion, in August, 1994, of a phase II SBIR grant awarded in September 1992.
See "Item 1--Business, Research and Development."

       Research and development expenses decreased by $1.5 million to $3.1
million during fiscal 1994 as compared to fiscal 1993. This decrease is
primarily attributable to a one-time, non-cash charge of $2.7 million which
represented the estimated fair market value of common stock issued to MBI in
connection with the license agreement amendment in July 1993 included in the
fiscal 1993 amount. See "Item 1--Business, Relationship with the Medical Biology
Institute." Adjusting for this charge, fiscal 1994 research and development
expenses increased by $1.1 million from fiscal 1993, primarily as a result of
increased costs related to the clinical development of LIDAKOL and preclinical
development work on LMI.

       General and administrative expenses increased to $2.6 million during
fiscal 1994 from $2.1 million in fiscal 1993. The increase in fiscal 1994
expenses were attributable primarily to increases in legal fees, consulting
fees, increased expenses associated with the Company's directors and officers
liability insurance and increases in costs associated with the Company's
securities listing on the NASDAQ National Market System. Included in fiscal 1994
consulting expense is a non-cash expense of $245,000 incurred in connection with
a two-year consulting agreement entered into in February 1993 pursuant to which
the Company issued options to purchase shares of its Class A Common Stock at an
exercise price below the estimated fair market value on the date of grant.
During fiscal 1995, the Company recorded additional non-cash expenses
approximating $82,000 in connection with the issuance of these options.
    

       Contract research expenses increased during fiscal 1994 by $154,000 as
compared to fiscal 1993. This increase is directly related to the increased
contract research activity related to the hu-PBL-SCID mouse technology noted
above.


                                     - 22 -
<PAGE>   26
         As a result of the foregoing revenues and expenses, the Company's net
loss decreased to $4.8 million during fiscal 1994 from $6.1 million in fiscal
1993.

   
LIQUIDITY AND CAPITAL RESOURCES

         Since inception, the Company has financed its operations primarily
through the sale of equity and debt securities and stockholder loans raising an
aggregate $33.9 million (net of issuance costs) through September 30, 1995.
After deducting repayments of stockholder loans and subordinated notes totaling
$323,000 and $625,000, respectively, and technology license fee payments to MBI
totaling $958,000, net cash provided from financing activities through
September 30, 1995 was $33.1 million.

         At September 30, 1995, the Company had cash, cash equivalents and
short-term investments totaling $10.0 million and working capital of $8.6
million, as compared to $17.4 million and $16.8 million, respectively, at
September 30, 1994.  Cash utilized by the Company to fund operating activities
for fiscal 1995 and from inception to September 30, 1995, was $9.3 million and
$22.6 million, respectively, as a result of net losses incurred during these
periods.  In addition, $93,000 and $420,000 of cash was utilized for capital
expenditures during fiscal 1995 and from inception to September 30, 1995,
respectively.  Offsetting such cash utilization during fiscal 1995 was the 
receipt of net proceeds from the exercises of certain outstanding options and 
warrants totaling $1.9 million.

         Subsequent to September 30, 1995 the Company received gross proceeds
of approximately $15 million from the sale of $1.5 million of Class A Common
Stock and $13.5 million of Convertible Notes ("Notes") in a private financing.

         The Notes accrue interest at an annual rate of 7% beginning six months
from the issue date with the principal due and payable two-years from the issue
date.  The Notes are convertible into Class A Common Stock at a price equal to
80% of the average closing bid price of the Company's Class A Common Stock for
seven trading days prior to the date of conversion.  The Notes may be converted
into Class A Common Stock in installments commencing February 1996 through
April 1996.

         The Notes are convertible into an aggregate maximum of 5,513,018
shares of the Company's Class A Common Stock at the option of the holders (with
each Note convertible into a pro-rata amount of such maximum number).  Any
Notes not converted are due and payable two years from the issue date.   In the
event that shares of Class A Common Stock cannot be issued upon request for
conversion due to the above referenced maximum share limitation, the Company is
immediately obligated to repay the principal of that portion of the Notes which
cannot be converted plus a premium equal to 25% of such principal plus any
accrued and unpaid interest.  (See "Description of Securities - Convertible
Notes Due 1997-1998").
    



                                      -23-
<PAGE>   27
   
         At December 31, 1995 the Company had additional exercisable warrants
and options outstanding which, if fully exercised, would result in the
aggregate issuance of approximately 7.3 million shares of the Company's Class A
Common Stock and would result in approximate gross proceeds to the Company of
$17 million.  Included in such warrants and options are Class D Warrants,
exercisable into approximately 1.8 million shares of the Company's Class A
Common Stock at an exercise price of $1.50 per share.  Such warrants are
redeemable by the Company, at a price of $.05 per warrant, upon 30 days notice
if the average closing bid price of the Company's Class A Common Stock for the
30 days prior to the notice exceeds $3.45 per share.  In the event the Company
does call the Class D Warrants for redemption, there can be no assurance
regarding the number of warrants which would be exercised or the amount of
proceeds which the Company would receive.  The remaining exercisable options
and warrants are not redeemable by the Company and can be exercised by the
holders at various times through 2004.  The average exercise price of the
remaining exercisable options and warrants is approximately $2.2831 per share
which is below the market price of the Company's Class A Common Stock on
December 31, 1995.  There can be no assurance that voluntary option and warrant
exercises will continue to occur in the future.

         The Company had available cash, cash equivalents and short term
investments of approximately $16.5 million at December 31, 1995.  The Company
expects to continue to incur substantial operating losses for the foreseeable
future.  The Company's available funds are not sufficient to permit the Company
to commercialize LIDAKOL in the United States and certain foreign markets or to
complete development or commercialize any other proposed pharmaceutical
products.  Accordingly, the Company may be required to raise substantial
additional capital or to collaborate with one or more large pharmaceutical or
biotechnology companies which could provide the necessary financing and
expertise to complete clinical development, manufacture and package finished
product and obtain regulatory approvals to market its products.  Furthermore,
the Company may not have sufficient funds to repay the Notes in the event the
Notes are not converted or if the Company becomes obligated to repay the Notes
in lieu of conversion.  There can be no assurance that the Company can
successfully obtain such additional capital or enter into the collaborative
arrangements necessary to fully develop or commercialize any of its proposed
products on acceptable terms, or to repay the Notes, if not converted.

                                    BUSINESS

GENERAL
   
         LIDAK Pharmaceuticals ("LIDAK" or the "Company") is a development
stage company organized to engage in research, development and
commercialization of innovative pharmaceutical products.  The Company was
incorporated in California in 1988 and since inception has operated in one
business segment -- research and development of pharmaceutical products.  The
Company is currently focusing on the development and commercialization of 1)
its patented therapeutic product n-docosanol 10% cream (LIDAKOLTM), as a
topical treatment for oral herpes (cold sores or fever blisters), and 2) its
patented Large Multivalent Immunogen ("LMI") technology as a potential
immunotherapeutic vaccine treatment for malignant melanoma and other human
cancers.

         During fiscal 1995, a Phase 3 clinical trial of LIDAKOL as a topical
treatment for oral herpes was completed in Europe by the Company's European
licensing partner, Yamanouchi Europe.  Three additional Phase 3 clinical trials
of LIDAKOL for the same indication conducted by the Company in the U.S. and
Canada have been recently completed and results of these trials are expected in
the first calendar quarter of 1996.
    
         To date, the Company has entered into four licensing agreements
relating to the marketing of LIDAKOL.  In November 1991, the Company entered
into an agreement with Yamanouchi Europe, b.v., formerly Brocades-Pharma, b.v.
of the Netherlands ("Yamanouchi"), under which Yamanouchi received rights to
market certain topical indications of LIDAKOL in certain European and other
countries.  In July 1993, the Company entered into a licensing agreement with
CTS Chemical Industries, Ltd. ("CTS"), a subsidiary of CTS Ltd., located in
Kiryat Malachi, Israel, under which CTS received rights to market certain
topical indications of LIDAKOL in Israel.  In July 1994, the Company entered
into an agreement with Boryung Pharmaceuticals Company, Ltd. ("Boryung"),
located in Seoul, Korea, under which Boryung received the rights to market
certain topical indications of LIDAKOL in the Republic of Korea.  In October
1994, the Company entered into an agreement with Grelan Pharmaceutical Co.,
Ltd. ("Grelan"), located in Tokyo, Japan, under which Grelan received rights to
market certain indications of LIDAKOL in Japan.  In each of the territories
covered by the above agreements, as well as in the United States and other
territories not covered by these agreements, marketing of LIDAKOL is subject to
obtaining appropriate government approvals.  The Company is currently seeking
licensing and/or other collaborative arrangements with respect to LIDAKOL in
the United States and other territories not covered by the above agreements.
   
         The Company's second current area of focus is the development of new
therapeutic approaches to cancer and viral infections using the LMI technology.
This technology involves the use of antigen-containing artificial cell
membranes to stimulate the immune system's defense against cancer and viral
diseases.  In December 1995, the Company initiated a Phase 1/Phase 2 clinical
trial of LMI in patients with malignant melanoma pursuant to an IND approved by
the FDA. The Company's rights to the LMI technology, and certain other
technologies, derive from a licensing agreement with Medical Biology Institute
("MBI"), a non-profit research organization founded in 1981 by Dr. David H.
Katz, the founder, President and Chief Executive Officer of the Company.

         The Company has experienced significant losses since inception and its
business is subject to significant risks.  The Company does not expect LIDAKOL,
LMI or any other of its proposed products to be available for commercial sale
for several years, if at all.  Assuming that the Company is successful in
obtaining applicable regulatory approvals, it will still be necessary to enter
into additional licensing or other collaborative arrangements with
pharmaceutical or biotechnology companies which have sufficient financial
resources and expertise and/or to raise substantial additional financing and
hire appropriate personnel in order for the Company to successfully
commercialize LIDAKOL for oral herpes in the United States.  In order for the
Company to successfully
    

                                      -25-
<PAGE>   29
   
commercialize other indications of LIDAKOL, LMI, or any other technologies, it
will be necessary to enter into additional licensing or other collaborative
arrangements with pharmaceutical or biotechnology companies which will bear the
cost of completing the remaining non- clinical development, the required
clinical trials and regulatory approval process and marketing of such products,
if approved, and/or to raise substantial additional financing and hire
appropriate personnel.

         There can be no assurance that the results from the Phase 3 clinical
trials of LIDAKOL in the U.S. and Canada or future clinical trials of LMI will
demonstrate satisfactory efficacy and safety to support the filing of New Drug
Applications ("NDA") with the FDA or other marketing approval applications with
regulatory agencies outside the U.S., that the FDA and/or other regulatory
agencies outside the U.S. will not require the Company to perform additional
clinical trials or that the FDA and/or other regulatory agencies outside the
U.S. will ultimately grant marketing approval for these products. There can be
no assurance that additional non-clinical and clinical testing will demonstrate
that the Company's other technologies will meet the safety and efficacy
requirements to complete development and obtain appropriate regulatory
marketing approvals.  Furthermore, there can be no assurance that the Company
will be able to raise sufficient additional capital to complete development
efforts and commercialize any of its proposed products or that additional
licensing arrangements can be established on terms favorable to the Company, or
at all.
    
RESEARCH AND DEVELOPMENT
   
         LIDAKOL:  Company scientists have developed a therapeutic compound,
n-docosanol, trademarked under the name LIDAKOL, which has demonstrated
anti-viral and anti-inflammatory properties.  The Company has been focusing on
approval for LIDAKOL as a topical treatment for oral herpes infections.  During
fiscal 1995, a Phase 3 clinical trial of LIDAKOL as a topical treatment for
oral herpes was completed in Europe by Yamanouchi, the Company's licensing
partner in Europe.  In this double blind study, LIDAKOL was compared to
acyclovir (Zovirax(R)) 5% cream in over 300 patients initiating treatment at
early stage of a recurrent herpes episode.  Results of this trial demonstrated
that LIDAKOL showed statistically comparable therapeutic efficacy to Zovirax 5%
cream,  a product which is approved by European regulatory authorities as a
treatment for this indication.  Zovirax 5% cream is not available in the U.S.
and Zovirax ointment, which is available in the U.S., has not been approved by
the FDA for use as a treatment for recurrent oral herpes.  Demonstrating
comparable efficacy to an approved product is a requirement for obtaining
regulatory approval in most major European countries ("European Regulatory
Approval").  Results of this trial will be used by Yamanouchi, along with
results from the U.S./Canada placebo controlled trials described below, for
submission to the appropriate regulatory agencies for marketing approval in
Europe as clear efficacy versus placebo is also a requirement for European
Regulatory Approval.  Demonstrating comparative efficacy to an approved product
is not a requirement for approval in the United States where only efficacy
versus placebo is relevant.

         In November 1994, the Company initiated two double-blind placebo
controlled Phase 3 clinical trials in sites in both the U.S. and Canada.  These
trials were designed to evaluate LIDAKOL versus placebo in patients with both
early and late stage episodes of oral herpes.  In April 1995, a third Phase 3
trial was initiated in the U.S. evaluating LIDAKOL versus placebo in only early
stage patients.  In aggregate these three trials include over 1,000 patients at
25 clinical sites in the U.S. and Canada.  If the results of these
placebo-controlled trials demonstrate that using LIDAKOL results in a
statistically and clinically significant reduction in the average healing time
of the herpes episode, the Company plans to submit an NDA to the FDA for
marketing approval of LIDAKOL in the U.S. and a New Drug Submission ("NDS") to
the Health Protection Branch for marketing approval in Canada.  Results of
these trials are expected to be available in the first calendar quarter of
1996.  See "Business-General".
    
                                      -26-
<PAGE>   30
   
         The Company has recently initiated two separate Phase 2 clinical
studies in AIDS patients of LIDAKOL as a topical treatment for Karposi's
Sarcoma cutaneous lesions (KS) and Molluscum Contagiosum (MC), and is also
investigating the possibility of initiating additional clinical trials for
other topical indications of LIDAKOL which may include therapeutic use in
genital herpes, shingles, burns, wound healing, fungal infections and other
skin conditions, although no specific plan has been established for initiation
of such trials.  In addition, the Company has preliminary data indicating that
the topical formulation of LIDAKOL might be beneficial in preventing sexually
transmitted HIV.

         The Company is also developing LIDAKOL for systemic (internally
administered) anti-viral and anti-inflammatory use.  Preclinical studies
indicate that systemically formulated LIDAKOL inhibits viral replication of
certain lipid-enveloped viruses.  Several medically significant diseases are
caused by these viruses which include herpes, shingles, cytomegalovirus (CMV),
influenza, respiratory syncytial virus (RSV), hepatitis and HIV.

         Patents covering medical and veterinary uses of the topical and
systemic formulations of LIDAKOL have been issued to LIDAK in the U.S. and
Europe.  The Company has additional foreign patent applications pending
covering topical and systemic uses of LIDAKOL and has been granted rights under
certain United States and foreign patents and patent applications relating to
ophthalmic uses of LIDAKOL held by a third party.  See "Patents and Proprietary
Rights."

         LARGE MULTIVALENT IMMUNOGEN (LMI):  Utilizing LMI technology acquired
pursuant to its license agreement with MBI, the Company is attempting to
develop anti-cancer and anti-viral therapeutic products.  See "Relationship
with Medical Biology Institute".  This technology incorporates artificial cell
membranes containing cancer or virus antigens to stimulate the immune system,
in particular cytotoxic T lymphocytes ("CTL") or "killer cells", to attack and
kill the cancer cells or virus infected cells.  CTL's play a major role in the
immune system's defense against diseases.  Provided they are effectively
stimulated into their killing action, CTL's can recognize foreign antigens on
cancer or virus-infected cells and kill such cells.  The LMI approach has been
shown to effectively stimulate and enhance cancer-specific CTL responses
against a variety of tumors in mice, and, when combined with traditional
chemotherapy, has been shown to significantly improve survival rates of
cancer-bearing mice.  In December 1995, the Company initiated a Phase 1/Phase 2
clinical trial of LMI in patients with malignant melanoma pursuant to an IND
approved by the FDA.

         In August 1993, the Company entered into an agreement with Ribi
Immunochem Research, Inc. ("Ribi") under which Ribi granted the Company a
license to use Ribi's melanoma cell lines in the clinical development of LMI
technology for use in malignant melanoma.  The Company granted Ribi an option
for an exclusive license to commercialize the Company's LMI technology with
Ribi's melanoma cell lines for the treatment of melanoma.  This agreement does
not restrict the Company from using its LMI technology for the treatment of
melanoma using melanoma antigens from other sources.
    
         Although research efforts are at an early stage, Company scientists
believe that the LMI approach may also be effective for stimulating enhanced
virus-specific CTL responses, thereby providing the opportunity to also develop
improved therapies and vaccines for viral diseases.
   
         Patents covering the use of LMI to treat human tumors have been issued
to MBI in the U.S. and Europe.  The rights to these patents belong to the
Company through the license agreement with MBI described under "Relationship
with Medical Biology Institute" below (the "MBI" Agreement).  Both U.S. and
foreign patents are pending for use of LMI as a treatment for viral diseases.
See "Patents and Proprietary Rights."
    

                                      -27-
<PAGE>   31
   
         FREE FATTY ACIDS (FFA):  Using technology acquired pursuant to its
license agreement with MBI, Company scientists have developed an assay which
rapidly measures, with high precision, levels of unbound FFA in blood plasma
and other tissue fluids.  See "Relationship with Medical Biology Institute".
Significant variations in blood plasma levels of unbound FFA are associated
with several diseases including cancer, heart disease and diabetes.  The
Company's FFA assay can be used in the attempt to verify a direct correlation
between unbound FFA levels and specific diseases.  Company scientists are
attempting to further develop this technology for use as a clinical assay for
predicting, diagnosing and monitoring the course of specific diseases.  The FFA
assay is currently available for sale to the medical research community through
a non-exclusive distribution agreement with Molecular Probes, Inc. of Eugene,
Oregon, although such sales have not and are not expected to result in
significant revenues to the Company.  Both U.S. and foreign patents have been
issued for the FFA technology.  The rights to these patents belong to the
Company through the MBI Agreement.  See "Patents and Proprietary Rights."

         HUMAN IMMUNE SYSTEM-RECONSTITUTED SCID MOUSE TECHNOLOGY:  The human
immune system-reconstituted SCID mouse technology (hu- PBL-SCID), which the
Company acquired pursuant to the MBI Agreement, creates a functional human
immune system in mice which have a genetic defect known as Severe Combined
ImmunoDeficiency ("SCID") by reconstituting such mice with human blood cells.
See "Relationship with Medical Biology Institute".  Certain aspects of the
human immune system are thereby created to function in laboratory animals.  The
Company believes there may be both commercial and scientific applications of
the hu-PBL-SCID mouse technology.  The focus of work with this model has been
diseases of the human immune system, including AIDS.  This model permits basic
studies on the infection of human cells with human viruses, such as Human
Immunodeficiency Virus ("HIV"), without risk to human life and efficacy testing
of possible vaccines for prevention of disease or drugs for therapy.

         To date, the Company has completed work under twelve contract research
agreements pursuant to which the Company used hu- PBL-SCID mice infected with
HIV to screen compounds developed by other pharmaceutical and biotechnology
companies for potential therapeutic efficacy in human AIDS and other
virus-induced diseases, although no such contractual agreements were completed
or initiated during fiscal 1995.  The Company has, from time to time,
subcontracted portions of the services performed under such agreements to MBI.
The Company will continue to make this research service available to other
pharmaceutical and biotechnology companies.  The Company does not expect that
long term future revenue from contract research agreements to test compounds in
hu-PBL- SCID mice will be significant, however, both U.S. and foreign patents
have been issued for the hu-PBL-SCID technology.  The rights to these patents
belong to the Company through the MBI Agreement.  See "Patents and Proprietary
Rights".

         OTHER RESEARCH AND DEVELOPMENT:  The Company is also conducting and/or
supporting research and development efforts on other technologies developed at
MBI including work related to the inhibition of complement activation, IgE
regulation, hematopoietic stem cell development and epidermal cell migration
function.  See "Relationship with Medical Biology Institute".  Research and
development efforts relating to the FFA, hu-PBL-SCID and other technologies are
at an early stage.  There can be no assurance that efforts to develop
commercial applications of these technologies will be continued.  In the event
that the Company proceeds with efforts to develop commercial applications of
these technologies, it may require additional financing either from
collaborative arrangements with pharmaceutical or biotechnology companies or
from other sources to commercialize any such applications of this technology.
There can be no assurance that the required development and testing will be
successfully completed, and result in safe and effective products for human
use, that the Company will be able to raise additional financing or that the
Company will be able to enter into licensing or other collaborative
arrangements on favorable terms, if at all.

RELATIONSHIP WITH MEDICAL BIOLOGY INSTITUTE
   
         In October 1988, the Company entered into an exclusive  license
agreement with Medical Biology Institute, a non-profit research organization
founded by David H. Katz, M.D.  Dr. Katz serves as President, Chief Executive
Officer and a director of MBI.  MBI was incorporated in California in 1981 to
conduct interdisciplinary basic research in biological sciences.  MBI currently
conducts research on a variety of projects funded predominantly by Federal
grants.  Certain of the founders, scientific consultants, staff scientists and
administrative personnel of the Company are affiliated with and/or employed by
MBI.  See "Human Resources." The MBI Agreement was amended in 1993 and 1994.

         Under the MBI Agreement, as amended, the Company has been granted an
exclusive worldwide license to all technology and know-how of MBI which had
been developed or which was under development as of the original date of the
MBI Agreement and a right of first preference to license future technology of
MBI through the year 2013 subject to restrictions, if any, in the funding
agreements by which MBI develops the technology.  The Company expects that, if
rights to additional technologies developed at MBI are acquired pursuant to
right of first preference under the MBI Agreement, the Company will assume
responsibility including funding, for the commercial development efforts
including remaining research and development, clinical testing and regulatory
approvals.
    
         MBI currently leases office and laboratory facilities in La Jolla,
California.  The lease expires in 1997.  MBI's laboratories are designed for
all phases of biological, biochemical, molecular biology and immunochemical
studies, including tissue culture facilities, walk-in environmental rooms,
facilities for recombinant DNA experimentation and modern computer equipment.
MBI maintains a modern vivarium for breeding and housing of certain rodents in
ample numbers to meet the needs of its researchers.  The Company entered into a
sublease agreement with MBI for laboratory and administrative facilities,
equipment and services.  The MBI Agreement provides that MBI will perform
research services for the Company at its request on a fee-for-service basis not
to exceed MBI's cost of providing such services, including reasonable overhead
and administrative costs.  Excluded from the computation of such fees are
salaries of scientists also employed by the Company, as well as the costs of
facilities, equipment and administrative services already included in the
sublease agreement.

         There can be no assurance that the Company will have the ability to
satisfy all of its obligations under the MBI Agreement, that the MBI Agreement
will result in the development of any additional products or technologies, that
MBI will be able to continue to receive adequate research funding, or that MBI
will be able to attract and/or maintain qualified scientific or administrative
personnel.  Modification or termination of the MBI Agreement could have a
material adverse effect on the Company.

GOVERNMENT REGULATIONS

         The manufacture and sale of pharmaceutical products under development
by the Company are subject to extensive regulation by the FDA in the United
States and by comparable regulatory agencies in certain foreign countries.  The
FDA has established guidelines and safety standards which are applicable to the
preclinical evaluation and clinical investigation of therapeutic products and
stringent regulations which govern the manufacture and sale of such products.
   
         The process of obtaining FDA approval for a new therapeutic product,
such as LIDAKOL or LMI, usually takes a significant amount of time and
substantial resources.  The steps typically required before such a product can
be produced and marketed for human use include preclinical evaluation in vitro
and in animal models,
    

                                      -29-
<PAGE>   33
   
the filing of an IND, the conduct of human clinical investigations and the
filing and of a NDA which must be approved by the FDA.
    

         Preclinical studies are conducted in vitro and in animal models in
order to gain preliminary information on the safety and efficacy of a drug.
The results of such preclinical studies are submitted to the FDA as part of the
IND application.  After the sponsor files an IND, the sponsor may commence
investigating the drug in humans within 30 days unless otherwise notified by
the FDA.

   
         The human clinical testing program for a drug generally involves three
phases.  Phase 1 investigations are conducted on volunteers or, in the case of
certain anti-tumor agents, on volunteers with a terminal disease to determine
the maximum tolerated doses and any side effects of the product.  Phase 2
studies are conducted on a small number of patients with the disease or
condition to be studied, in order to determine whether the product demonstrates
some level of effectiveness against the disease and to determine the most
effective doses and schedule of administration.  Phase 3 studies involve
wide-scale, well controlled investigations on patients who have the disease or
condition for the purpose of determining whether the drug is safe and effective
in a rigorously controlled trial.  Data from Phase 1, Phase 2 and Phase 3
trials are submitted to the FDA in an NDA.  The NDA involves considerable data
collection, verification and analysis, as well as the preparation of summaries
of the manufacturing and testing processes, preclinical studies and clinical
trials.  The FDA's Center for Drug Evaluation and Research must approve an NDA
for a drug before the drug may be marketed in the United States.

         The Company has recently completed a series of Phase 3 clinical trials
of LIDAKOL as a topical treatment of oral herpes infections under an IND with
the FDA, results of which are expected in the first calendar quarter of 1996.
In December 1995, the Company initiated a Phase 1/Phase 2 human clinical trial
of its LMI technology as a treatment for late stage melanoma under an IND
approved by the FDA.  A Phase 1/Phase 2 trial combines the safety and efficacy
testing previously described into one trial.  In addition, the Company has
recently initiated two separate Phase 2 clinical studies in AIDS patients of
LIDAKOL as a topical treatment for Karposi's Sarcoma cutaneous lesions (KS) and
Molluscum Contagiosum (MC).  No other IND applications have been filed with the
FDA or any other agency with respect to any of the Company's other products or
technologies.
    

         At such time, if ever, that the Company begins marketing its products
for commercial sale in the United States, any manufacturing operations which
may be established within or outside the United States will be subject to
rigorous regulation, including the need to comply with Federal Good
Manufacturing Practice Regulations.  See "Manufacturing and Marketing."  The
Company may also be subject to regulation under the Occupational Safety and
Health Act, the Environmental Protection Act, the Toxic Substance Control Act,
Export Control Act and other present and future laws of general application.

         Additionally, the handling, care and use of laboratory mice, such as
the hu-PBL-SCID mice, and rats is subject to the Guidelines for the Humane Use
and Care of Laboratory Animals published by the NIH.

         The Company intends to seek approval to market its products in foreign
countries which may have regulatory processes that materially differ from that
of the FDA.  The Company anticipates that it will rely upon the pharmaceutical
or biotechnology companies to which it may license its products, or independent
consultants, to seek approvals to market its products in foreign countries.
There can be no assurance that approvals to market any of the Company's
products can be obtained in any country.  Approval to market a product in any
foreign country does not necessarily indicate that approval can be obtained in
other countries.

                                      -30-
<PAGE>   34
PATENTS AND PROPRIETARY RIGHTS

   
         The Company owns five United States and two European patents, and has
additional foreign patent applications pending relating to the topical and
systemic uses of LIDAKOL and has been granted rights under certain United
States and foreign patents and patent applications relating to ophthalmic uses
of LIDAKOL held by a third party.  In addition, the Company has been granted
rights to certain United States and foreign patents and patent applications
related to LMI, FFA, and the hu-PBL-SCID technologies pursuant to the MBI
Agreement.    The MBI Agreement requires the Company to pay the costs of
pursuing and obtaining patents on the licensed technology and any improvements
thereto.  See "Research and Development" and "Relationship with Medical Biology
Institute".
    

         There can be no assurance that the claims in the pending patent
applications will issue as patents, that any issued patents will provide the
Company with significant competitive advantages, or that challenges will not be
instituted against the validity or enforceability of any patent owned by the
Company or, if instituted, that such challenges will not be successful.  The
cost of litigation to uphold the validity and prevent infringement of the
Company's patents could be substantial.  Furthermore, there can be no assurance
that others will not independently develop similar technologies or duplicate
the Company's technology or design around the patented aspects of the Company's
technology.  There is no assurance that the Company's proposed technology will
not infringe patents or other rights owned by others, licenses to which may not
be available to the Company.  Finally, NIH regulations provide that if
federally-funded institutions do not timely pursue patent applications for
patentable inventions, the government can exercise its right to own such
inventions.  Accordingly, the Company must monitor MBI's filing of patent
applications in order to protect the value of its license agreement with MBI.

         The process for the approval of patent applications in foreign
countries may differ significantly from the process in the United States.
Approval in one country does not necessarily indicate that approval can be
obtained in other countries.  The patent authorities in each country administer
that country's laws and regulations relating to patents independently of the
laws and regulations of any other country and the patents must be sought and
obtained separately.

         In some cases, the Company may rely on trade secrets and
confidentiality agreements to protect its innovations.  There can be no
assurance that trade secrets will be established, or that secrecy obligations
will be honored, or that others will not independently develop similar or
superior technology.  To the extent that consultants, key employees or other
third parties apply technological information independently developed by them
or by others to Company projects, disputes may arise as to the proprietary
rights to such information which may not be resolved in favor of the Company.

PRODUCT LIABILITY

   
         The testing, marketing and sale of pharmaceutical products entails a
risk of product liability claims by consumers and others.  Claims may be
asserted against the Company by end users of any of the Company's proposed
products which may be developed.  The Company has obtained product liability
insurance coverage in the amount of $2,000,000 per incident and in aggregate
for its clinical trials and, although the Company will attempt to obtain
additional product liability insurance prior to marketing any of its proposed
products, there is no assurance that the Company will be able to obtain such
insurance or, if obtained, that such insurance can be acquired at a reasonable
cost or will be sufficient to cover all possible liabilities.  In the event of
a successful suit against the Company, lack or insufficiency of insurance
coverage could have a material adverse effect on the Company.  Further, certain
distributors of pharmaceutical products require minimum product liability
insurance coverage as a condition precedent to purchasing or accepting products
for distribution.  Failure to satisfy such
    

                                      -31-
<PAGE>   35
insurance requirements could impede the ability of the Company to achieve broad
distribution of its proposed products, which would have a material adverse
effect upon the business and financial condition of the Company.

MANUFACTURING AND MARKETING

   
         The Company has established certain contractual manufacturing
relationships with respect to the manufacturing of LIDAKOL and LMI.  The
Company does not have the resources to directly manufacture or directly market
LIDAKOL or any other products which it may develop on a large commercial scale.
To successfully commercialize LIDAKOL or any other products, it will be
necessary for the Company to enter into collaborative arrangements with
pharmaceutical or biotechnology companies to assist in funding development
costs, including the costs of clinical testing necessary to obtain regulatory
approvals, and costs of manufacturing and marketing.  The Company believes that
these arrangements will be more effective in promoting and distributing its
products in view of the Company's limited resources and the extensive marketing
networks and large advertising budgets of established companies.  Such
third-party arrangements, however, will reduce the Company's profit margin on
its products.
    

         In November 1991, the Company entered into a licensing agreement with
Yamanouchi for the clinical development, manufacturing, marketing and
distribution of LIDAKOL in certain European and other countries.  Pursuant to
this agreement the Company and Yamanouchi have and will continue to jointly
design clinical trials of LIDAKOL to be conducted by Yamanouchi to confirm
clinical efficacy and generate data to support regulatory approval for market
introduction of LIDAKOL for topical treatment of herpes in covered territories.

   
         In July 1993, the Company entered into a licensing agreement with CTS
Chemical Industries, Ltd. ("CTS"), a subsidiary of CTS Ltd., located in Kiryat
Malachi, Israel, for the promotion of LIDAKOL in Israel, including obtaining
governmental approvals for its manufacture and distribution.  Separate clinical
trials in Israel are not required for marketing approval.  Accordingly, CTS
will be able to file for marketing approval based on the data generated in U.S.
and Canadian clinical trials, if successful, and European clinical trials.  See
"See Research and Development-LIDAKOL".

         In July 1994, the Company entered into a licensing agreement with
Boryung Pharmaceuticals Company, Ltd. located in Seoul, Korea, for the
promotion of LIDAKOL in the Republic of Korea, including obtaining governmental
approvals for its manufacture and distribution. In Korea, certain local
clinical trials, in addition to clinical data generated in the U.S., Canada and
Europe, are required in order to apply for marketing approval.  To date, no
local clinical trials have been initiated.  See "Research and
Development-LIDAKOL".

         In October 1994, the Company entered into a licensing agreement with
Grelan Pharmaceutical Company, Ltd. located in Tokyo, Japan, for the promotion
of LIDAKOL in Japan, including obtaining governmental approvals for its
manufacture and distribution.  In Japan complete Phase 1, 2 and 3 clinical
trials, conducted in Japan, are required in order to apply for marketing
approval.  To date, no local clinical trials have been initiated.

         The Company is currently discussing licensing agreements for LIDAKOL
in the United States and other territories not covered by the above agreements
with  other pharmaceutical companies.  The Company may ultimately decide to
establish its own manufacturing and/or marketing capability, at least for
certain products or certain applications related thereto, in which case it
would require substantial additional funds and personnel.  There can be no
assurances, however, that the Company will be able to finalize any substantial
additional licensing arrangements on favorable terms, if at all, or that the
Company will be able to raise additional financing necessary to develop and
market LIDAKOL and any of its other products.

COMPETITION

         The pharmaceutical industry is characterized by rapidly evolving
technology and intense competition.  Many companies of all sizes, including
major pharmaceutical companies and specialized biotechnology companies, are
engaged in activities similar to those of the Company.  Many of the Company's
competitors have substantially greater financial and other resources, larger
research and development staffs and, unlike the Company, have significant
experience in pre-clinical testing, human clinical trials and other regulatory
approval procedures.  In addition, colleges, universities, governmental
agencies and other public and private research organizations will continue to
conduct research and are becoming more active in seeking patent protection and
licensing arrangements to collect royalties for use of technology that they
have developed, some of which may be directly competitive with that of the
Company.  In addition, these institutions compete with commercial firms, such
as the Company, in recruiting highly qualified scientific personnel.  The
Company does not have the resources and does not intend to compete with major
pharmaceutical companies on a wide scale basis in the areas of clinical
testing, regulatory approvals, manufacturing and marketing.  See "Manufacturing
and Marketing" and "Government Regulations."

   
         The Company's first proposed product, LIDAKOL, if successfully
developed and approved for commercialization for the treatment of oral herpes,
will compete with other anti-viral products marketed for the treatment of
herpes viruses including Zovirax(R) (acyclovir) and Valtrex(R) (valaciclovir), 
products marketed by Glaxo-Wellcome Corp., and Famvir(R) (famciclovir), a 
product marketed by Smith Kline Beecham. Various over-the-counter preparations
are also sold for the symptomatic relief of oral herpes.  In addition, there 
are products and compounds being developed by other pharmaceutical and
biotechnology companies for treatment of various indications of herpes,
including pencyclovir, a product being developed by Smith Kline Beecham.  
There can be no assurance that LIDAKOL, if successfully developed and approved
for sale by the FDA, will gain widespread acceptance by the medical community
or consumer market.

         The Company's LMI technology will compete with technologies being
developed by other companies and academic institutions which attempt to
stimulate an immune response.  There can be no assurance that these competing
technologies will be less efficacious than LMI or that LMI will gain widespread
acceptance by the medical community.

Annual Meeting of Shareholders.  The terms of the Class II Directors (currently

         The California General Corporation Law permits a corporation through
its Articles of Incorporation to eliminate the personal liability of its
directors to the corporation or its stockholders for monetary damages for
breach of fiduciary duty of loyalty and care as a director, with certain
exceptions.  The exceptions include a breach of the director's duty of loyalty,
acts or omissions not in good faith or which involve intentional misconduct or
knowing violation of law, improper declarations of dividends, and transactions
from which the directors derived an improper personal benefit.  The Company's
Articles of Incorporation exonerates its directors from monetary liability to
the fullest extent permitted by this statutory provision.  The Company has also
purchased and maintained directors and officers insurance coverage in the
aggregate amount of $5,000,000 since August 1992.  The insurance policies
indemnify the Company's officers and directors against certain liabilities and
expenses which they may incur in their capacities as officers and directors of
the Company.

         The Company has been advised that it is the position of the Securities
and Exchange Commission that insofar as the foregoing provision may be invoked
to disclaim liability for damages arising under the Act, that provision is
against public policy as expressed in the Act and is therefore unenforceable.

EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT ARRANGEMENTS

         In April 1993, the Company entered into an employment agreement with
David H. Katz, M.D. (the "1993 Employment Agreement") which replaced the prior
employment agreement between Dr. Katz and the Company dated September 9, 1988,
as amended, September 19, 1989 and October 8, 1989, respectively (the "1988
Employment Agreement").  The 1993 Employment agreement provides that Dr. Katz's
term of employment by the Company shall be at an "at will" basis, subject to
the discretion of the Board, for an annual base salary of $207,692.  Dr. Katz's
salary is reviewed by the Compensation Committee of the Board of Directors of
the Company from time to time to determine, within the Board's discretion,
whether an increase is appropriate.  In March 1994, the Board increased Dr.
Katz's annual base salary to $228,000.  In addition, Dr. Katz's base salary
increases or decreases in proportion to any future mutually agreed upon
increase or decrease in the percentage amount of time Dr. Katz allocates to the
Company (currently 75%) compared with MBI (currently 25%).

         In the event that Dr. Katz is terminated for any reason other than
cause, Dr. Katz will receive a severance payment in the amount of his base
salary.  Dr. Katz is also entitled to all benefits generally available to the
Company's employees.

         The 1993 Employment Agreement further provides that, except for Dr.
Katz's involvement with MBI, Dr. Katz's services shall be exclusive to the
Company.  The terms of the 1993 Employment Agreement prohibit Dr. Katz from
engaging in any other businesses or providing services of a business or
commercial nature to any other person or organization unless such activity is
fully disclosed to the Company and approved by the Company's Board of
Directors.

CERTAIN RELATIONSHIPS AND TRANSACTIONS
   
         David H. Katz, President and CEO of the Company is also President and
CEO of MBI.  In October 1988, the Company and MBI entered into a twenty-year
licensing agreement (the "MBI Agreement") which granted the Company an
exclusive, worldwide license to all existing technology of MBI and a right of
first preference to license future technology developed at MBI.  The MBI
Agreement was amended in 1993 and 1994.  Under the MBI Agreement, as amended,
the Company has been granted an exclusive worldwide license to all technology
and know-how of MBI which had been developed or which was under development as
of the original date of the MBI Agreement and a right of first preference to
license future technology of MBI through the year 2013 subject to restrictions,
if any, in the funding agreements by which MBI develops the technology.  The
Company expects that, if rights to additional technologies developed at MBI are
acquired pursuant to right of first preference under the MBI Agreement, the
Company will assume responsibility including funding, for the commercial
development efforts including remaining research and development, clinical
testing and regulatory approvals.

         The Company and MBI have also entered into agreements for the leasing
of facilities and equipment and the use of certain research and administrative
services.  During the fiscal year ended September 30, 1995, the Company
incurred charges to MBI totaling $399,251 and $189,389 respectively, under
these agreements.

_______________

(1)      Mr. Arsenault is employed as a registered representative of Whale
         Securities Co., L.P.

(2)      Dr. Katz is a director and President and Chief Executive Officer of
         the Company.  The amount listed does not include options to 1,877,000
         shares of Class A Common Stock and 375,000 shares of Class B Common
         Stock; nor does the amount include options to purchase 43,000 shares
         of Class A Common Stock and 10,000 shares of Class B Common Stock held
         by a member of his family.  See "Principal Shareholders."

         To the Company's knowledge, except for David H. Katz, none of the
foregoing persons, after the sale of all shares of Class A Common Stock offered
hereby, would own more than 1% of the aggregate of the Company's outstanding

                              PLAN OF DISTRIBUTION

         The Class A Common Stock issuable to the Selling Shareholders upon
conversion or exercise of the Securities may be offered and sold from time to
time as market conditions permit in the over-the-counter market, or otherwise,
at prices and terms then prevailing or at prices related to the then current
market price, or in privately negotiated transactions.  At the date of this
Prospectus, no underwriting arrangements have been entered into by the Selling
Securityholders.  The shares offered hereby may be sold by one or more of the
following methods, without limitation:  (a) a block trade in which a broker or
dealer so engaged will attempt to sell the shares as agent but may position and
resell a portion of the block as principal to facilitate the transaction, (b)
purchases by a broker or dealer as principal and resale by such broker or
dealer for its account pursuant to this Prospectus, (c) ordinary brokerage
transactions and transactions in which the broker solicits purchasers and (d)
face-to-face transactions between sellers and purchasers without a
broker-dealer.  In effecting sales, brokers or dealers engaged by the Selling
Securityholders may arrange for other brokers or dealers to participate.  Such
brokers or dealers may receive commissions or discounts from Selling
Securityholders in amounts to be negotiated.  Such brokers and dealers, any
other participating brokers or dealers, and the Selling Securityholders, may be
deemed to be "underwriters" within the meaning of the Act in connection with
such sales and any profits realized or commissions received may be deemed
underwriting compensation.

         The Company will pay certain expenses incident to the offering and
sale of the securities offered hereby to the public by the Selling
Securityholders.  The Company will not pay for, among other expenses,
commissions and discounts of underwriters, dealers or agents or the fees and
expenses of counsel for the Selling Securityholders, if any.


                           DESCRIPTION OF SECURITIES

COMMON STOCK

GENERAL

   
         The Company is authorized to issue 99,490,000 shares of Class A Common
Stock, no par value, 30,470,132 of which were issued and outstanding at
December 31, 1995, and 510,000 shares of Class B Common Stock, no par value,
283,000 of which were issued and outstanding at December 31, 1995.
    

         Holders of Class A Common Stock and Class B Common Stock have equal
rights to receive dividends when, as and if declared by the Board of Directors
out of funds legally available therefor.

         Holders of Class A Common Stock have one vote for each share held of
record and holders of Class B Common Stock have five votes for each share held
of record on all matters to be voted on by the stockholders.  The Class A
Common Stock and Class B Common Stock vote as one class on all matters
requiring stockholder approval except that under California law the affirmative
vote of a majority of the outstanding shares of Class A Common Stock and a
majority of the outstanding shares of Class B Common Stock, each voting
separately as a class, is required for any amendment to the Company's Articles
of Incorporation which would alter or change the powers, preferences or special
rights of, or increase or decrease the number of shares of, or create a new
class or series of shares having rights, preferences or privileges prior to,
each respective class of the Company's common stock.

                                      -47-
<PAGE>   51
         Holders of both classes of Common Stock are entitled upon liquidation
of the Company to share ratably in the net assets available for distribution
subject to the rights, if any, of holders of any preferred stock then
outstanding. Shares of both classes of Common Stock are not redeemable and have
no preemptive or similar rights. The Class B Common Stock may be converted into
Class A Common Stock on a share for share basis at any time at the election of
the holder and will automatically convert into Class A Common Stock upon sale or
transfer other than to another holder of Class B Common Stock.

DIVIDEND POLICY

         The Company does not anticipate paying cash dividends on its common
stock in the foreseeable future.

PREFERRED STOCK

   
The Company is authorized to issue up to 10,000,000 shares of Preferred Stock
containing such rights, preferences, privileges and restrictions as the
Company's Board of Directors may determine.

CONVERTIBLE NOTES DUE 1997 AND 1998

In November, 1995, December 1995 and January 1996, the Company sold $7,500,000,
$3,000,000 and $3,000,000, respectively, in principal amount of Convertible
Notes ("Notes") for an aggregate total of $13,500,000. The Notes bear interest
of 7%, payable quarterly, with the principal due and payable two years from the
date of issue if and to the extent that the Notes are not previously converted.
The Notes are convertible at the option of the holder (subject to the maximum
share and timing limitations set forth below) into Class A Common Stock at a
price equal to 80% of the average closing bid price for the Class A Common Stock
on the NASDAQ for the seven trading days prior to the date of conversion. The
conversion schedule with respect to $10.5 million of the principal amount of the
Notes is as follows: One third may be converted on February 9, 1996, March 10,
1996 and March 30, 1996, respectively. The conversion schedule with respect to
$3.0 million of the principal amount of the Notes is as follows: One third may
be converted on February 24, 1996, March 25, 1996 and April 24, 1996,
respectively.

The $13.5 million of Notes are convertible into an aggregate maximum of
5,513,018 shares of the Company's Class A Common Stock at the option of the
holders, with each individual Note limited to a pro-rata amount of such number
of shares. To the extent the Notes are not converted they are due and payable
two years from the issue date.

In the event that shares of Class A Common Stock underlying a particular Note
cannot be issued upon request for conversion due to the above referenced maximum
share limitations, the Company is immediately obligated to repay the principal
of that portion of the Note which is presented for conversion which cannot be
converted plus a premium equal to 25% of such principal plus any accrued and
unpaid interest. At its option, the Holder(s) of $3.0 million of the principal
amount of the Notes can require the Company to issue shares of Class A Common
Stock at their then fair market value in exchange for the above-referenced
principal and premium payment.

WARRANTS

         Class D Warrants. Each Class D Warrant entitles the registered holder
to purchase one share of Class A Common Stock at an exercise price of $1.50 from
the date of issuance until 5:00 p.m., New York City Time, on February 26, 1997.
The Class D Warrants are redeemable by the Company on 30 days' written notice at
a redemption price of $0.05 per Class D Warrant, if the closing price of the
Class A Common Stock for any 30 consecutive trading days ending within 15 days
of the notice of redemption averages in excess of $3.45 per share. All Class D
Warrants must be redeemed if any are redeemed. As of December 31, 1995,
1,780,021 Class D Warrants were outstanding.

         Class E Warrants. Each Class E Warrant entitles the registered holder
to purchase one share of Class A Common Stock at an exercise price of $0.20 from
the date of issuance until 5:00 p.m. New York City time on January 7, 1997. The
Class E Warrants are not redeemable. As of December 31, 1995, 100,000 Class E
Warrants were outstanding.

   
         General. The Class D Warrants were issued pursuant to warrant
agreements under which American Stock Transfer & Trust Company, New York, New
York serves as warrant agent. The warrants are evidenced by warrant certificates
in registered form. The warrants provide for adjustment of the exercise price
and for a change in the number of shares issuable upon exercise or market price
to protect holders against dilution in the event of a stock dividend, stock
split, combination or reclassification of the common stock or upon issuance of
shares of common stock at prices lower than the warrant exercise price then in
effect other than issuances upon exercise of options granted to employees,
directors and consultants to the Company, or options to be granted under the
Company's stock option plan.
    

         The exercise prices of all outstanding Warrants were determined by
negotiation between the Company and its previous underwriters, and should not be
construed to be predictive of or to imply that any price increases in the
Company's securities will occur or be sustained.

         A warrant may be exercised upon surrender of the warrant certificate on
or prior to its expiration date (or earlier redemption date) at the offices of
American Stock Transfer & Trust Company, New York, New York, with the form of
"Election to Purchase" on the reverse side of the warrant certificate completed
and executed as indicated, accompanied by payment of the full exercise price (by
certified or bank check payable to the order of the Company) for the number of
shares with respect to which the warrant is being exercised. Shares issued upon
exercise of warrants and payment in accordance with the terms of the warrants
will be fully paid and nonassessable.

   
         The Company has agreed not to solicit exercises of the Class D Warrants
other than through Whale Securities Co., L.P. ("Whale"). Upon exercise of the
Class D Warrants, the Company will pay Whale a fee of 5% of the aggregate
exercise price, if (i) the market price of the Company's Class A Common Stock on
the date the warrant is exercised is greater than the then exercise price of the
warrant; (ii) the exercise of the warrant was solicited by a member of the
National Association of Securities Dealers, Inc.; (iii) the warrant is not held
in a discretionary account; (iv) disclosure of compensation arrangements was
made both at the time of the offering and at the time of exercise of the warrant
and (v) the solicitation of exercise of the warrant was not in violation of Rule
10b-6 promulgated under the Securities Exchange Act of 1934.
    

                                     - 49 -
<PAGE>   53
         No warrants confer upon any warrantholder any voting or other rights of
a stockholder of the Company. Upon notice to the warrantholders, the Company has
the right to reduce the exercise price or extend the expiration date of the
warrants.

TRANSFER AGENT AND WARRANT AGENT

   
         American Stock Transfer & Trust Company, New York, New York currently
serves as transfer agent for the Common Stock and warrant agent for the Class D
Warrants.
    

REGISTRATION RIGHTS

   
         The Company has registered under the Act the shares of Class A Common
Stock underlying the Class D and E Warrants pursuant to registration rights
previously granted. The Company has agreed to use its best efforts to keep such
registration effective until all of such shares of Class A Common Stock are sold
pursuant to such registration, or an opinion of counsel satisfactory to the
Company is received that the shares may be sold under the provisions of Rule
144(k) under the Act.
    

         In March 1994, the Company also registered under the Act the Class A
Common Stock underlying certain options granted in July 1993 ("July 1993
Options") on a Form S-3 Registration Statement. The Company has agreed to keep
such registration statement effective during the ten year term of the exercise
of the July 1993 Options.

   
         In January 1996, the Company also registered all 5,513,018 shares
potentially of Class A Common Stock potentially issuable upon conversion of the
$13,500,000 Convertible Notes due 1997 and 1998 plus 481,651 shares of Class A
Common Stock sold to an investor as part of the placement of such Notes.

INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Stockholders of
   LIDAK Pharmaceuticals:

We have audited the accompanying balance sheets of LIDAK Pharmaceuticals (a
development stage enterprise) as of September 30, 1994 and 1995, and the
related statements of operations, stockholders' equity (deficit), and cash
flows for each of the three years in the period ended September 30, 1995 and
for the period August 31, 1988 (inception) to September 30, 1995.  These
financial statements are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these 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, such financial statements present fairly, in all material
respects, the financial position of LIDAK Pharmaceuticals at September 30, 1994
and 1995, and the results of its operations and its cash flows for each of the
three years in the period ended September 30, 1995 and the period August 31,
1988 (inception) to September 30, 1995 in conformity with generally accepted
accounting principles.

The Company is in the development stage as of September 30, 1995.  As discussed
in Note 1 to the financial statements, the Company has not yet completed
product development, obtained required regulatory approvals or verified the
market acceptance and demand for its products.

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1.  THE COMPANY AND ITS SIGNIFICANT ACCOUNTING POLICIES

    THE COMPANY - LIDAK Pharmaceuticals (the "Company") was incorporated in the
state of California on August 31, 1988.  The Company is organized to engage in
research, development, and commercialization of innovative pharmaceutical
products.

    BASIS OF ACCOUNTING - The Company has not yet completed product
development, obtained required regulatory approvals or verified the market
acceptance and demand for its products.  The Company has completed certain
clinical trials on one of its products under an Investigational New Drug
("IND") application filed with the United States Food & Drug Administration
("FDA") and has filed an IND application with the FDA to initiate clinical
trials on a second product.  The Company is also currently performing research
in connection with other technologies.  Accordingly, the Company's activities
have been accounted for as those of a "development stage enterprise" as set
forth in Financial Accounting Standards Board Statement No. 7.

    CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS - Cash equivalents consist of
highly liquid investments purchased with original maturities of three months or
less.  Short-term investments represent certificates of deposit, U.S.
government securities, commercial paper, and other money market instruments
with maturities of less than twelve months.  Cash equivalents and short-term
investments are carried at cost, which approximates market value.  At October
1, 1995, the Company adopted Statement of Financial Standards ("SFAS") No. 115,
"Accounting for Certain Investments in Debt and Equity Securities".
In accordance with SFAS 115, management determined that the appropriate
classification of its investments is "held-to-maturity". There was no cumulative
effect as a result of adopting SFAS 115 in the current year, and in accordance
with SFAS 115, prior years' financial statements have not been restated.

    CONCENTRATION OF CREDIT RISK - The Company invests its excess cash in
certificates of deposit, U.S. government securities, commercial paper, and
other money market instruments and has established guidelines relative to
diversification and maturities in an effort to maintain safety and liquidity.
These guidelines are periodically reviewed and modified to take advantage of
trends in yields and interest rates.  The Company has not experienced any
significant losses on its cash equivalents or short-term investments.

    DEPRECIATION - Depreciation is provided over the estimated useful lives of
the property (generally five years) on the straight-line method.  Depreciation
expense for the years ended September 30, 1993, 1994 and 1995 and the period
from inception to September 30, 1995 was $32,068, $56,818 and $74,799 and
$178,729, respectively.

    PATENT COSTS - Legal expenses incurred in connection with applications for
patents are capitalized.  Amortization of the costs of approved patent

                                      F-11
<PAGE>   66
applications is provided over the useful lives of the patents.  For patent
applications that are abandoned, accumulated costs are charged to expense.

    CONTRACT RESEARCH REVENUES AND COSTS - Revenues from research contracts are
recognized on the percentage of completion method.  Under this method, revenues
and costs are recognized as the work is performed based on the ratio that
incurred costs bear to the estimated total costs.  Provisions for anticipated
losses would be made in the period in which they first become determinable.

    GRANTS - Revenues from grants are recognized during the period in which
related grant expenditures are incurred.

    RESEARCH AND DEVELOPMENT - Research and development costs are expensed as
incurred.

    INCOME TAXES - The Company adopted Statement of Financial Accounting
Standards ("SFAS") No. 109, "Accounting for Income Taxes", effective October 1,
1993.  This Statement supersedes Accounting Principles Board Opinion No. 11,
which had been in use by the Company.  There was no cumulative effect of
adopting SFAS No. 109.

2.  MBI AND THE LICENSE AGREEMENT

    Medical Biology Institute ("MBI"), is a non-profit research organization
incorporated in 1981 to conduct interdisciplinary basic research in biological
sciences.  The President, Chief Executive Officer and director of the Company
is also President, Chief Executive Officer and a director of MBI.

    The Company and MBI entered into a twenty year licensing agreement
("Agreement") as of October 10, 1988 which granted the Company an exclusive,
worldwide license to all existing technology of MBI and a right of first
preference to license future technology arising from the research and
development efforts of MBI.  As consideration for entering into the agreement,
MBI was granted 2,000,000 shares of the Company's preferred stock, which was
recorded at the nominal value of $1.  Upon completion by the Company of its
initial capitalization in May 1990, the Company became obligated to MBI for
$900,000 payable in three equal annual installments.  The payments were made in
May 1990, 1991 and 1992, respectively.  The present value of the obligation
(approximately $818,000) as of May 1990 was reflected in the financial
statements as a charge to research and development expense in May 1990.  In
addition, MBI shall receive 10% of all net license fees and 20% of royalties
relating to sub licenses of the licensed technology.  For products manufactured
and sold by the Company, MBI will receive royalties of 6% and 3% of sales
relating to patented (issued or pending) and non patented licensed technology,
respectively.

     Prior to the amendment of the Agreement, if the annual fees and royalties
paid to MBI failed to exceed $100,000 for the calendar year ending December 31,
1995 or any calendar year thereafter then MBI had the right to convert the
license to a non-exclusive license upon six months notice.  Fees and royalties
on future technology are subject to negotiation.

                                      F-12
<PAGE>   67
    In July 1993 the Agreement was amended.  Pursuant to the terms of the
amendment, the Company issued 1,500,000 shares of Class A common stock to MBI
as consideration for a 5-year extension to its exclusive technology rights
(until October 10, 2013) and a 5-year postponement (until December 31, 2000) of
the Company's obligation to pay minimum royalties to MBI.  Additionally, MBI
waived its rights to 1,500,000 shares of the Company's Series A preferred stock
which were being held in escrow (See Note 5).  The value of the common stock
issued ($2,670,000) was reflected in the financial statements as a charge to
research and development expense in July 1993.

    In November 1993 the Company and MBI entered into a Grant-in-Aid agreement
as an addendum to the October 10, 1988 license agreement.  Under this grant the
Company agreed to provide direct laboratory support to fund a specific research
program.  Such grant will automatically renew for additional one year periods
until terminated in writing by the Company.

    In July 1994 the Agreement was further amended to provide for future
research funding and support for projects not included in the initial license
agreement.  This amendment provides for the transfer of ownership rights for
each specific project during the time it is being funded by the Company.

UNDERWRITER AGREEMENTS
               On May 8, 1990, the Company entered into an agreement with an 
underwriter for the sale of common stock units. Among other things, the
agreement provides for: (i) underwriter shall have a right of first refusal to
act as underwriter on any offerings of securities for a period of five years,
(ii) upon the exercise of any warrants after May 8, 1991 the Company shall pay
underwriter a fee of 4% of the aggregate exercise price if the market price of
the Company's common stock exceeds the exercise price on the date of exercise,
and (iii) certain anti-dilution rights.

       On November 3, 1993, the Company entered into an agreement whereby the
underwriter waived its right of first refusal and any and all rights under a
merger and acquisition agreement dated May 15, 1990. As compensation for such
waivers, the Company paid the underwriter $40,000 and issued non-qualified
options exercisable until November 3, 1996 into 50,000 shares of the Company's
Class A common stock at an exercise price of $6.75 per share.

UNIT PURCHASE OPTIONS
       On May 15, 1990, the underwriter of the Company's initial public offering
received an option to purchase 100,000 common stock units, each common stock
unit consisting of five shares of Class A common stock and five redeemable Class
A warrants, at an exercise price of $6.00 per common stock unit. In September
1992, the number of common stock units and the exercise price per unit were
adjusted to 158,730 and $3.78, respectively, in accordance with certain
anti-dilution provisions included in the option agreement. The option was
non-transferable and was exercised during fiscal 1993.

       In July 1991 such underwriter also received options to purchase 0.9
preferred stock units, each preferred stock unit consisting of 106,667 shares of
Series B preferred stock and 53,334 Class D warrants, in connection with a
private placement of Series B preferred stock. The options were exercised in
fiscal 1993.

ESCROW AGREEMENT
       Pursuant to an agreement between the Company and the underwriter of the
Company's initial public offering, 3,783,750 shares of Class B common stock,
1,500,000 shares of Series A convertible preferred stock, and options to
purchase 2,216,250 shares of Class B common stock were placed in an escrow
account to be held until January 1994. During fiscal 1992, 70,000 of these
options were exercised resulting in 70,000 shares of Class A common stock being
placed in the escrow account. In July 1993, certain holders of the shares and
options placed in escrow waived all rights to their respective shares and
options, resulting in the cancellation of 2,240,250 shares of Class B common
stock, 1,500,000 shares of Series A convertible preferred stock and options to
purchase 1,603,500 shares of Class B common stock. At September 30, 1993, there
were 70,000 shares and 1,546,500 shares, respectively, of Class A common and
Class B common stock remaining in escrow which were cancelled during fiscal
1994.

STOCK OPTIONS
       In March 1994 the Company's shareholders approved the adoption of the
1994 Stock Option Plan ("the 1994 Plan") pursuant to which an aggregate of
750,000 shares of Class A Common Stock were reserved for issuance. Such options
may be granted to officers, directors, employees and consultants of the Company.
The options are to be granted at an exercise price of at least fair market value
on the date of grant and generally vest over a three year period. The 1994 Plan
provides for an automatic annual grant of an option to purchase 10,000 shares to
each director who is not also an employee of the Company. The 1994 Plan shall
terminate on January 14, 2004. In March, 1995 the Company s shareholders voted
to increase the shares reserved for issuance under the plan to an aggregate of
1,100,000 shares. At September 30, 1995, there were 465,167 shares of Class A
Common Stock remaining available for grant under the 1994 Plan.

       Prior to the adoption of the 1994 Plan, the Company had other stock
option plans which provided for the grant of options to purchase up to 1,200,000
and 1,500,000 shares of Class A and Class B common stock, respectively, to key
employees and others at an option price of at least fair market value at date of
grant. In March 1994 and November 1989, respectively, the Company terminated
these plans as to the issuance of new options.

       In September 1988, under an employment agreement with its President and
Chief Executive Officer, the Company issued options to purchase 900,000 shares
of Class B common stock at an option price of $.0125 per share representing the
estimated fair market value on the date of grant. Effective in August 1990, the
employment agreement was amended to provide for the grant of options to purchase
an additional 600,000 shares of Class B common stock at an option price of
$.0125 per share (which was below the estimated fair market value of $.05 on the
date of grant resulting in the recording of related compensation expense) in
return for the cancellation of certain anti-dilution rights. The options were
fully exercisable when issued and expire on September 9, 2003. In July 1993
options to purchase 1,125,000 shares were canceled and replaced pursuant to
certain of the July 1993 grants discussed below. As of September 30, 1995, fully
vested options to purchase 375,000 shares of Class B common stock remained
outstanding.

       In February 1993 the Company granted options to purchase 500,000 shares
of Class A common stock to a consultant (see Note 5) at an option price of $0.50
per share (which was below the estimated fair market value of $1.48 on the date
of grant). In June 1994 the Company issued additional options to purchase
100,000 shares of Class A common stock at an exercise price of $2.25 pursuant to
the consulting agreement. In February 1995, the consultant exercised options to
purchase 500,000 shares of the Company's Class A Common Stock at the option
price of $0.50 per share.

       In July 1993 the Company granted options to purchase an aggregate of
3,843,750 shares of Class A common stock to certain current employees,
consultants, directors and original investors of the Company at an option price
of $3.56 per share. Recipients of these options waived all of their respective
rights to an aggregate of 3,843,750 shares of Class B common stock and options
to purchase Class B common stock held in an escrow account. These options were
fully exercisable when issued and expire on July 17, 2003.

       In September 1994 the Company reduced the exercise price on options
granted to certain employees, officers and consultants to purchase 3,285,250
shares of Class A and Class B common stock to $2.75 per share.

       The Company has provided a valuation allowance against the net deferred
tax assets recorded as of September 30, 1994 and 1995 due to uncertainties as to
their ultimate realization. The net operating loss and research credit
carryforwards expire through 2009. In the event of certain ownership changes,
the Tax Reform Act of 1986 imposes certain restrictions on the amount of net
operating loss carryforwards which may be used in any year by the Company.

8.  NET LOSS PER SHARE
       Net loss per share is computed using the weighted average number of
common shares outstanding during the period. Certain shares of common stock
which were outstanding during the fiscal years ended September 30, 1993 and 1994
were excluded from the number of shares used in the calculation of weighted
average number of common shares outstanding during those periods as these shares
had been placed in escrow and were subject to forfeiture. All shares which had
been placed in escrow were subsequently cancelled (see Note 5). Common
equivalent shares have been excluded from the number of shares used in the
calculation of weighted average number of common shares outstanding as their
inclusion would be antidilutive.

9.  RELATED PARTY TRANSACTIONS

  Private Placement - In July 1991 the Company's President and Chief Executive
Officer purchased nine preferred stock units in a private placement offering

ITEM 17.  UNDERTAKINGS

         The undersigned Registrant hereby undertakes to provide to the
Underwriter at the closing specified in the underwriting agreement, certificates
in such denominations and registered in such names as required by the
Underwriter to permit prompt delivery to each purchaser.

         The undersigned Registrant hereby undertakes:

         1.    To file, during any period in which offers or sales are being 
made, a post-effective amendment to this registration statement:

               i.   To include any prospectus required by Section 10(a)(3) of
the Securities Act of 1933;

               ii.  To reflect in the prospectus any facts or events arising
after the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the registration
statement; and

               iii. To include any material information with respect to the plan
of distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement.

         2.    That, for the purpose of determining any liability under the Act,
each such post-effective amendment 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.

                                     II - 4
<PAGE>   81
         3.    To remove from registration by means of a post-effective 
amendment any of the securities being registered which remain unsold at the
termination of the offering.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the provisions of its Restated Articles of
Incorporation and By-Laws of the Registrant, the California General Corporation
Law or otherwise, 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 Act and is therefore unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the issuer 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.
