                               PROSPECTUS SUMMARY

THIS SUMMARY PROVIDES AN OVERVIEW OF SELECTED INFORMATION CONTAINED ELSEWHERE IN
THIS PROSPECTUS AND DOES NOT CONTAIN ALL OF THE INFORMATION YOU SHOULD CONSIDER.
THEREFORE, YOU SHOULD ALSO READ THE MORE DETAILED INFORMATION IN THIS PROSPECTUS
AND OUR FINANCIAL STATEMENTS. WHEN WE REFER IN THIS PROSPECTUS TO THE "COMPANY,"
"WE," "US," AND "OUR," WE MEAN OPTICON MEDICAL, INC., A DELAWARE CORPORATION,
TOGETHER WITH OUR SUBSIDIARIES AND THEIR RESPECTIVE PREDECESSORS, UNLESS
OTHERWISE INDICATED. THIS PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS AND
INFORMATION RELATING TO OPTICON MEDICAL, INC. SEE "FORWARD-LOOKING STATEMENTS
MAY PROVE TO BE INACCURATE" ON PAGE 11.

                                  OUR BUSINESS

         Our predecessor, Immune Response, Inc. was incorporated on May 24,
1984, as Med-Mark Technologies, Inc. for the purpose of marketing medical
products. We became Immune Response, Inc. on November 10, 1986. We established
and operated the Clinical Testing and Research Division until May 1991, when we
sold all of our assets to Infinity Laboratories, Inc. due to a lack of
commercial viability. Until recently, we had been inactive, seeking and
evaluating alternative business opportunities.

         On February 25, 2000, as part of a merger among us, Opticon Medical,
Inc., an Iowa corporation, and Opticon Acquisition Corporation, a Delaware
corporation and our wholly-owned subsidiary, we acquired the business of Opticon
Medical, Inc., a development stage enterprise formed to develop, manufacture,
and market disposable devices to manage and control the symptoms of urinary
incontinence in adults. In the merger, Opticon Medical, Inc. was merged into our
wholly-owned subsidiary, which then changed its name from Opticon Acquisition,
Inc. to Opticon Medical, Inc. On July 27, 2000, pursuant to shareholder
approval, Immune Response merged into its wholly-owned subsidiary, Opticon
Medical, Inc. As a result of the mergers, our sole business now consists of the
research and development activities relating to the OPTICON(TM), a disposable,
silicone indwelling valved catheter designed to manage urinary incontinence, and
other related products for urology markets.

         We are a development stage company, and to date have had no sales and
generated no revenues.

We are located at 7001 Post Road, Dublin, Ohio  43016, telephone:
(614) 336-2000.

                                  RISK FACTORS

         An investment in our common stock is highly speculative, involves a
high degree of risk, and should be made only by investors who can afford a
complete loss. You should carefully consider the following risk factors, as well
as the other information contained in this prospectus, before purchasing our
common stock.


WE ARE A DEVELOPMENT STAGE ENTERPRISE AND MAY NEVER HAVE POSITIVE EARNINGS OR
CASH FLOW

         Our current business is limited to research and development activities
relating to the OPTICON(TM) and related products, from which we have yet to
derive any revenues. Therefore, our business is subject to risks incident to any
early stage business, including the absence of earnings. As of December 31,
1999, we had an accumulated deficit of $4,365,416. Until a successful commercial
launch of the OPTICON(TM) (which is by no means assured) we will realize little,
if any, revenue, and will be dependent upon the proceeds from our recent
debenture/preferred stock financing and follow-on rounds of capitalizations to
fund operations. See "Business - Recent Developments."

WE HAVE NEVER HAD ANY SALES OR REVENUES AND HAVE A HISTORY OF LOSSES. WE ALSO
ANTICIPATE FUTURE LOSSES.

         We have been engaged primarily in the research, development and testing
of the OPTICON(TM) and related products. We have not had any commercial sales or
generated any revenues from the OPTICON(TM) or any other product to date and
have experienced operating losses since our inception, including those for
fiscal year 1999 totaling $799,873. We expect to incur substantial operating
losses and the rate at which such losses are incurred is expected to increase
relative to prior years as we prepare for the commercialization of the
OPTICON(TM). Until a successful commercial launch of the OPTICON(TM), which is
by no means assured, we will realize little, if any, revenue, and will be
dependent upon the proceeds of our recent debenture/preferred stock financing to
fund operations. There can be no assurance that we will ever generate revenues
or achieve profitability.

WE NEED TO RAISE ADDITIONAL CAPITAL IN 2000 IN ORDER TO BE SUCCESSFUL

         We will likely incur substantial expenditures during 2000 to further
the development and commercialization of the OPTICON(TM). We do not currently
have adequate funds to accomplish our objectives and anticipate that we may need
to raise additional capital in 2000. We are unsure whether capital will be
available at that time.

WE FACE CERTAIN PRODUCT DEVELOPMENT RISKS AND THE UNCERTAINTY OF REGULATORY
APPROVAL

         The OPTICON(TM) device is new and, accordingly, its safety and efficacy
has not yet been established. The production and marketing of our products,
including the OPTICON(TM), and our ongoing research and development activities
are subject to regulations by numerous government authorities in the United
States and other countries. The manufacture and sale of the OPTICON(TM) and
future products are subject to Food and Drug Administration review and approval,
which can be an expensive, lengthy and uncertain process. We received 510(k)
allowance to market the OPTICON(TM) Direct, a non-valved product, as a drainage
device in the United States, although we do not anticipate marketing the
OPTICON(TM) Direct at least until after introducing the OPTICON(TM). In February
1998, the FDA approved our petition to permit us to conduct human trials on
acute patient populations requiring short-term urinary management and to seek
market clearance for short-term use of the OPTICON(TM) via a 510(k) submission
rather than via the lengthier Pre-Market Approval process. The FDA, however,
currently requires the more extensive PMA process for qualifying transurethral
devices for the long-term management of incontinence. Once chronic use trials
begin, a PMA filing is expected within 24 months. The approval process for a PMA
application


                                      -5-
<PAGE>   8

entails longer and more complicated regulatory review, often taking 6 to 12
months or longer from the time of filing.

         Failure to complete clinical trials or obtain the necessary FDA
allowances or approvals, or to complete clinical trials or obtain such
allowances or approvals on a timely basis, would have a material adverse effect
on our business, financial condition and results of operations. In addition, the
FDA and various state agencies inspect medical device manufacturers (including
contract manufactures, such as we intend to employ) from time to time to
determine whether they are in compliance with applicable regulations, including
ones concerning manufacturing, testing, quality control and product labeling
practices. Noncompliance with applicable regulatory requirements (including
noncompliance by our third-party contract manufacturers) can result in, among
other things, fines, injunctions, civil penalties, recall or seizure of
products, total or partial suspension of production, failure of the government
to grant pre-market clearance or approval for devices, withdrawal of marketing
clearances or approvals, and criminal prosecution. The FDA also has the
authority to request recall, repair, replacement or refund of the cost of any
device we manufacture or distribute.

OUR PRODUCTS FACE THE UNCERTAINTY OF MARKET ACCEPTANCE

         The OPTICON(TM) represents a new approach to managing certain types of
urinary incontinence, and there can be no assurance that the OPTICON(TM) will
gain any significant degree of market acceptance even if necessary regulatory
clearances or approvals are obtained. We believe that recommendations by
physicians may be significant for market acceptance of the OPTICON(TM), and
there can be no assurance that we will obtain any such recommendations. In
addition, there can be no assurance that urinary incontinence sufferers in the
United States and abroad will accept the OPTICON(TM). Further, the incontinence
and urological device industry is highly competitive. In order to compete
successfully against other products, we must maintain competitive pricing.
Insufficient market acceptance of the OPTICON(TM) would have a material adverse
effect on our business, financial condition and results of operations.

OUR SUCCESS IS COMPLETELY DEPENDENT UPON THE SUCCESS OF THE OPTICON(TM)

         Although we intend to develop a family of products for urology and
incontinence care, we expect that substantially all of our revenues in the
near-term will be derived from the OPTICON(TM). Failure to successfully
commercialize the OPTICON(TM) would have a material adverse effect on our
business, financial condition and results of operations.

WE DO NOT HAVE ANY MANUFACTURING CONTRACTS AND WILL BE DEPENDENDENT UPON THIRD
PARTIES FOR MANUFACTURING

         Initially, we expect to contract with third parties for all of our
manufacturing and there can be no assurance that we will be able to enter into
acceptable contracts with appropriate third parties. In addition, we have
contracted with third parties for the creation of tooling, assembly, packaging
and sterilization. As a result, we will be dependent on such third parties to
produce our products efficiently and on a timely basis. Further, we will be
dependent on such third parties' quality control procedures. Failure of such
third parties to maintain adequate quality control or to manufacture products in
sufficient quantities and on a timely and cost-effective basis could have a
material adverse effect on our business, financial condition and results of
operations. Any interruption in supplies would also have a material adverse
effect on our business, financial condition and results of operations.

WE DO NOT HAVE ANY MARKETING AND SALES SUPPORT

         We currently have no employees dedicated solely to marketing and sales.
We expect to market our products initially through distribution alliances. In
the future, we expect to market our products for the incontinence market in part
through a direct sales force. There can be no assurance that we can build a
distribution alliance or an effective sales force, attract and retain our own
qualified marketing and sales group in the United States, or otherwise design
and implement an effective marketing and sales strategy for the OPTICON(TM) or
any future products we develop.


                                      -6-
<PAGE>   9

         We expect to market our products internationally principally through
distributors or strategic alliances. There can be no assurance that we will be
able to engage such distributors or strategic partners or that if retained such
distributors or partners will be able to successfully market and sell our
products.



OUR PRODUCTS FACE SIGNIFICANT COMPETITION AND OUR COMPETITORS MAY DEVELOP MORE
EFFECTIVE PRODUCTS

         Our ability to compete in the urinary incontinence management field
will depend primarily upon physician and consumer acceptance of the OPTICON(TM)
device, consistency of product quality and delivery, price, technical capability
and the training of health care professionals and consumers. Other factors
within and outside our control will also affect our ability to compete,
including our product development and innovation capabilities, our ability to
obtain required regulatory clearances, our ability to protect the proprietary
technology included in our products, our manufacturing and marketing
capabilities, our third-party reimbursement status, and our ability to attract
and retain skilled employees. Certain of our competitors have significantly
greater financial, technical, research, marketing, sales, distribution and other
resources than we have. The OPTICON(TM) is intended to be a management option
for the treatment of urinary incontinence, but it is not a permanent cure. The
development of new treatments that offer a permanent cure for urinary
incontinence could have a material adverse effect on our business, financial
condition and results of operations. There can be no assurance that our
competitors will not succeed in developing or marketing technologies and
products that are more effective or commercially attractive than any products
that we may offer, nor can there be any assurance that such competitors will not
succeed in obtaining regulatory clearance, introducing or commercializing any
such products before we do. Such developments could have a material adverse
effect on our business, financial condition and results of operations.

WE MAY NOT BE ABLE TO PROTECT OUR PATENTS OR PRODUCE OR MAINTAIN PROPRIETARY
TECHNOLOGY

         Our ability to compete effectively will depend, in part, on our ability
to develop and maintain proprietary aspects of our technology. Although we have
a number of patents relating to the shape of the balloon and to the design and
function of the discharge valve, there can be no assurance that our patents will
not be challenged, invalidated or circumvented in the future. Legal standards
related to the enforceability, scope and validity of patents are in transition
and are subject to uncertainty due to broad judicial discretion and evolving
case law. Moreover, there can be no assurance that our competitors, many of
which have substantial resources and have made substantial investments in
competing technologies, will not seek to apply for and obtain patents that will
prevent, limit or interfere with our ability to make, use and sell our products
either inside or outside the United States. The defense and prosecution of
patent litigation or other legal or administrative proceedings related to
patents is both costly and time-consuming, even if the outcome is favorable to
us. An adverse outcome could subject us to significant liabilities to third
parties, require disputed rights to be licensed from others or require us to
cease making, using or selling any products. There also can be no assurance that
any licenses required under any patents or proprietary rights would be made
available on terms acceptable to us, if at all.

         We also rely on unpatented proprietary technology, and there can be no
assurance that others may not independently develop the same or similar
technology or otherwise obtain access to our unpatented proprietary technology.
In addition, we cannot be certain that others will not independently develop
substantially equivalent or superseding proprietary technology, or that an
equivalent product will not be marketed in competition with our products,
thereby substantially reducing the value of our proprietary rights. There can be
no assurance that any confidentiality agreements between us and our employees,
consultants or contractors will provide meaningful protection for our trade
secrets, know-how or other proprietary information in the event of any
unauthorized use or disclosure of such trade secrets, know-how or other
proprietary information.

OUR PRODUCTS MAY NOT BE ELIGIBLE FOR THIRD-PARTY REIMBURSEMENT

         In the United States and many foreign countries, third-party
reimbursement is currently generally available


                                      -7-
<PAGE>   10

for surgical procedures for incontinence, but generally unavailable for
patient-managed products such as diapers and pads. Although we believe that
users of the OPTICON(TM) may ultimately be eligible for third-party
reimbursement, there can be no assurance that such reimbursement will become
available. The availability of third-party reimbursement for the OPTICON(TM) in
Europe will vary from country to country. If third-party reimbursement is
unavailable in the relevant European country or in the United States, consumers
will have to pay for the OPTICON(TM) themselves, resulting in greater relative
out-of-pocket costs of the OPTICON(TM) as compared to surgical procedures and
other management options for which third-party reimbursement is available.
Changes in the availability of third-party reimbursement for the OPTICON(TM),
for products of our competitors or for surgical procedures may affect the
pricing of the OPTICON(TM) or the relative cost to the consumer. We are not able
to predict the effect that the availability or unavailability of third-party
reimbursement for the OPTICON(TM) may have on the commercialization of the
OPTICON(TM) abroad or, ultimately, in the United States, but such effect may be
significant.

OUR PRODUCTS FACE INTERNATIONAL SALES AND OPERATIONS RISK

         We intend to sell the OPTICON(TM) and any future products to customers
outside the United States as well as domestically. International sales and
operations may be limited or disrupted by the imposition of government controls,
export license requirements, political instability, market instability, trade
restrictions, changes in tariffs or difficulties in staffing and managing
international operations. Foreign regulatory agencies often establish product
standards different from those in the United States, and any inability to obtain
foreign regulatory approvals on a timely basis could have an adverse effect on
our international business and our financial condition and results of
operations. Additionally, our business, financial condition and results of
operations may be adversely affected by fluctuations in currency exchange rates
as well as increases in duty rates and difficulties in obtaining export
licenses. There can be no assurance that we will be able to successfully
commercialize the OPTICON(TM) or any future product in any foreign market.

WE ARE DEPENDENT ON KEY PERSONNEL AND NEED ADDITIONAL PERSONNEL

         We are currently dependent on the services of our officers and
directors as well as our founder and other consultants. Our success is also
dependent in large part upon our ability to attract and retain key management
and operating personnel. Qualified individuals are in high demand and are often
subject to competing offers. In the immediate future, we will need to add
additional skilled personnel and to retain consultants in the areas of research
and development, regulatory affairs, marketing and manufacturing. There can be
no assurance that we will be able to attract and retain the qualified personnel
needed for our business. The loss of the services of one or more members of our
research or management group or the inability to hire additional personnel as
needed, would likely have a material adverse effect on our business, financial
condition and prospects. In addition, we do not have in force key man life
insurance policies on any of our key officers.

AS A MANUFACTURER AND MARKETER OF A CONSUMER PRODUCT, WE COULD EXPERIENCE
PRODUCT LIABILITY CLAIMS AND WE MAY NOT HAVE ADEQUATE INSURANCE COVERAGE

         We face an inherent business risk of exposure to product liability
claims in the event that a consumer is adversely affected by our prospective
products. Based on the nature of the OPTICON(TM) technology and our preliminary
clinical results, we are hopeful that the OPTICON(TM) may potentially lower
infection rates compared to traditional Foley catheters. Because the OPTICON(TM)
is a foreign body in the urethra, however, there is always a chance of urinary
tract infection. The OPTICON(TM) is also subject to other potential risks that
apply to all indwelling catheters and devices, including urethral complications
(balloon inflation in the urethra, urethral stricture, damage to the urethra if
catheter removal is attempted while balloon is inflated) and bladder
complications (hematuria due to irritation or infection, polypoid cystitis
associated with long-term use, bladder perforation). There can be no assurance
that our existing $2 million umbrella insurance policy is adequate to protect us
from any liability we might incur in connection with the clinical studies or
sales of the OPTICON(TM). In addition, we may require increased product
liability coverage as the OPTICON(TM) is commercialized. Such insurance is
expensive, and there can be no assurance that such insurance in the future will
be available on commercially reasonable terms, or at all, or that such
insurance, even if obtained, would adequately cover any product liability claim.
A product liability or


                                      -8-
<PAGE>   11

other claim with respect to uninsured liabilities or in excess of insured
liabilities could have a material adverse effect on our business, financial
condition and prospects.

YOU MAY HAVE DIFFICULTY BUYING AND SELLING OUR COMMON STOCK

         Our common stock is currently traded in the over-the-counter market on
the OTC Bulletin Board. There can be no assurance that our common stock will
continue to be listed on the OTC Bulletin Board or that a market for our common
stock will exist in the future should our stockholders wish to sell any of their
shares. There is no assurance that, if a market exists in the future, that it
will be an active, liquid or continuous trading market. The stock market has
experienced extreme price and volume fluctuations and volatility that has
particularly affected the market prices of many technology, emerging growth, and
developmental companies. Such fluctuations and volatility have often been
related or disproportionate to the operating performance of such companies.
Factors such as announcements of the introduction of enhanced services or
related products by us or our competitors may have a significant impact on the
market price of our common stock.

BECAUSE OUR COMMON STOCK IS A "PENNY STOCK," TRADING IN IT IS SUBJECT TO THE
PENNY STOCK RULES WHICH COULD AFFECT YOUR ABILITY TO RESELL THE STOCK IN THE
MARKET

         Our common stock is currently trading at a price below $5.00 per share,
subjecting trading in the stock to certain rules promulgated under the
Securities Exchange Act of 1934 requiring additional disclosures by
broker-dealers. These rules generally apply to any non-NASDAQ equity security
that has a market price of less than $5.00 per share, subject to certain
exceptions (a "penny stock"). Such rules require the delivery, prior to any
penny stock transaction, of a disclosure schedule explaining the penny stock
market and the risks associated therewith and impose various sales practice
requirements on broker-dealers who sell penny stocks to persons other than
established customers and accredited investors (generally defined as an investor
with a net worth in excess of $1,000,000 or annual income exceeding $200,000
individually or $300,000 together with a spouse). For these types of
transactions, the broker-dealer must make a special suitability determination
for the purchaser and have received the purchaser's written consent to the
transaction prior to the sale. The broker-dealer also must disclose the
commissions payable to the broker-dealer, current bid and offer quotations for
the penny stock and, if the broker-dealer is the sole market-maker, the
broker-dealer must disclose this fact and the broker-dealer's presumed control
over the market. Such information must be provided to the customer orally or in
writing before or with the written confirmation of trade sent to the customer.
Monthly statements must be sent disclosing recent price information for the
penny stock held in the account and information on the limited market in penny
stocks. The additional burdens imposed upon broker-dealers by such requirements
could discourage broker-dealers from effecting transactions in our common stock
which could severely limit the market liquidity of our common stock and our
stockholders' ability to sell them.

WE HAVE NEVER PAID A DIVIDEND AND DO NOT ANTICPATE DOING SO IN THE FORESEEABLE
FUTURE

         We have never paid or declared a dividend on our common stock and do
not anticipate doing so in the foreseeable future. We have accumulated
substantial losses since our inception and there can be no assurance that our
operations will result in sufficient revenues to enable us to operate at
profitable levels or to generate positive cash flow. Any earnings generated from
our operations will be used to finance our business and growth.

THE ISSUANCE OF THE COMMON STOCK TO THE SELLING STOCKHOLDERS MAY CAUSE DOWNWARD
PRICING PRESSURE AND WILL DILUTE OUR STOCKHOLDERS' PERCENTAGE OF OWNERSHIP

         The shares of preferred stock held by the selling stockholders are
convertible into common stock at a 35% discount to the market price of the
common stock at the time of conversion, which means that the potential dilution
of our stockholders' ownership will increase as our stock price goes down, since
the preferred stock is convertible at a floating rate that is a discount to the
market price. If the selling stockholders were to convert the preferred stock at



                                      -9-
<PAGE>   12

the prevailing market price as of the date of this prospectus, the conversion
would result in the issuance of approximately 3,134,408 additional shares of
common stock to the selling stockholders. In addition, the sale of the common
stock issued upon conversion of the preferred stock and exercise of the warrants
issued to the selling stockholders will put downward pricing pressure on our
common stock.

         We also expect to issue additional shares of our common stock to pay
dividends on the preferred stock, further diluting our stockholders' ownership
and putting additional downward pricing pressure on the common stock.

         We also have outstanding options and warrants to purchase common stock
that were issued pursuant to the exchange of options and warrants held by
Opticon Medical, Inc. stockholders before the merger. Additional warrants were
issued to the selling stockholders. If some or all of these options and warrants
are exercised, our stockholders would experience a dilution in their percentage
of ownership and their voting power.

         If we issue equity securities to raise funds, each stockholder's
interest may be reduced. Further, such equity securities may have rights,
preferences, or privileges senior to the common stock.

THE CONCENTRATION OF OWNERSHIP OF OUR COMMON STOCK MAY LIMIT YOUR ABILITY TO
INFLUENCE MATTERS

         Our directors, executive officers and principal stockholders (5% or
greater) collectively beneficially own or have the right to acquire under
currently exercisable options approximately 71.63% of our outstanding shares of
common stock. As a result, these stockholders will be able to exercise
significant influence over matters requiring stockholder approval, including the
election of directors and approval of significant corporate transactions. Such
concentration of ownership may have the effect of delaying or preventing a
change in control.

VOLATILITY OF MEDICAL TECHNOLOGY COMPANIES' SECURITIES MAY ADVERSELY EFFECT THE
MARKET PRICE OF YOUR STOCK

         Market prices of securities of medical technology companies, including
the shares of our common stock, have experienced significant volatility from
time to time. There may be volatility in the market price of our common stock
due to factors that may not relate to our performance. Various factors and
events, such as announcements by us or our competitors concerning new product
developments, governmental approvals, regulations or actions, developments or
disputes relating to patent or proprietary rights and public concern over
product liability may have a significant impact on the market price our common
stock.

                           PRICE RANGE OF COMMON STOCK

         Our common stock has been traded on the over-the-counter market since
July 1988. Trading in the our common stock was reported by National Quotation
Service's "Pink Sheets" until January 1992 when the common stock ceased being
quoted. Effective July 1999, our common stock is admitted for quotation on the
NASD OTC Bulletin Board under the symbol "IMUN." Effective July 27, 2000, as a
result of the merger of Immune Response, Inc. with and into Opticon Medical,
Inc, we began trading under the new symbol "OPMI" on the NASD OTC Bulletin
Board. The following table sets forth, for the periods indicated, the high and
low bid per share, as reported by Nasdaq Trading & Market Services.

Third Quarter 1999 ...............................    $0.9375    $0.5
Fourth Quarter 1999 ..............................    $0.7       $0.25
First Quarter 2000 ...............................    $6.5       $0.39
Second Quarter 2000 ..............................    $3.5       $0.375
Third Quarter 2000 (through August 21, 2000) .....    $1.75      $0.94

         The bid price quotations reflect inter-dealer prices, without retail
mark-up, mark-down or commission and may not represent actual transactions.

         On August 22, 2000, the last reported sale price of our common stock
was $1.50 per share. On August 22, 2000, there were 706 holders of record of
shares of our common stock. This figure excludes an indeterminate number of
stockholders whose shares are held in "street" or "nominee" name.

                                 DIVIDEND POLICY

         We have not paid a dividend on our common stock and do not anticipate
paying any dividends in the foreseeable future. We may never pay cash dividends
or distributions on our common stock. Whether we pay cash dividends in the
future will be at the discretion of our Board of Directors and will be dependent
upon our financial condition, results of operations, capital requirements, and
any other factors that the Board of Directors decides is relevant.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS

         Our working capital, derived from a Debenture/Preferred Stock financing
 completed in February 2000, was $1,736,780 at the end of the second quarter,
 and is expected to fund our planned operations into the second quarter of 2001,
 after which additional funds will be required for further business development.
 We will continue to apply our existing cash resources to executing the current
 stage of our business plan, specifically across four initiatives -
 infrastructure, product development, regulatory approval and manufacturing
 scale-up. Broadly, it is our plan to advance development to the point that
 initial market introduction of the OPTICON(TM) device is considered imminent,
 thereby establishing the basis for subsequent funding.

         We have been methodically building our organization and internal
capabilities, and will continue the hiring of key employees as the demands of
the business call for the requisite financial, engineering and management
skills. We have successfully recruited management and operating personnel in
both the areas of product development/engineering and clinical and regulatory
affairs. While the recruiting of additional operating personnel in these areas
is expected, we plan to continue to use outside contractors to some extent, as
the needs of the business dictate. We expect that manufacturing and assembly
operations will be contracted to outside sources, and the process of qualifying
and specifying these contractors is nearing completion. Marketing and business
development management will be added to the organization later in the cycle as
the product approaches market readiness. We currently expect to employ directly
a total of some 8-10 associates by the end of 2000.

         The primary focus of our product development activity currently centers
on integrating the final specifications of the first-generation female device
and creating the initial tooling which will facilitate the assembly of finished
devices for use in clinical trial. A final packaging design is also being
specified and sourced. A series of test equipment and test protocols have been
acquired or developed and are in routine use within our research and development
facility to better demonstrate product performance characteristics, to
facilitate failure mode analysis, and to further specify quality standards. We
plan to move the male-gender version of the device from prototype to pilot stage
following the completion of this critical phase of development for the female
configuration. We also hope to proceed in other developmental areas such as a
suprapubic configuration and an artificial sphincter, but the extent to which we
will be able to pursue development will be limited by resource constraints and
the prioritization of first-generation market entry.

         Conducting clinical trials to support a 510(k) submission for
short-term urinary management is our primary objective in regulatory affairs. We
have drafted a trial protocol which we plan to finalize with assistance from our
previously assembled network of clinical investigators, after which we plan to
consult with the FDA for guidance prior to proceeding. A meeting with FDA is
scheduled for early September. We believe that a statistically valid sampling of
patients can be studied over a relatively short 4-5 month time frame once the
Institutional Review Boards of each of our investigative sites grant their
approval to proceed. Assuming trial results remain satisfactory, we expect to
have made our submission to the FDA before the end of the first quarter of 2001.
Within that period of time, it is also our goal to have essentially completed
the process necessary to apply for the European CE marking - the regulatory
requirement for entering major foreign markets.

         Finally, production tooling is being preliminarily specified and
sourced so that we will be able to equip one or more contract manufacturers for
producing product components in scale quantities. Once we obtain regulatory
clearance, this will enable a marketing-level manufacturing capacity and provide
for meeting initial unit cost forecasts. Such tooling is significant in cost and
we have not been successful in attempting to arrange debt or leasing in advance
to mitigate the cash flow impact, primarily due to our pre-revenue status. This
may have an adverse impact by accelerating the need for cash infusion by several
months. We expect that we will need to raise additional capital early in 2001 in
order to complete development and commercialization of our first product.

         Underlying the operating plan described above is the objective to
secure sales and distribution channels to the urology markets in both the U.S.
and Europe. We continue to have dialog with a number of the established market
participants for creating a strategic alliance and as we get closer to
demonstrating market readiness, it is likely that one or more of these
discussions will become more meaningful and definitive.

                                    BUSINESS

BACKGROUND

         Immune Response, Inc. was incorporated in the State of Colorado on May
24, 1984, as Med-Mark Technologies, Inc. for the purpose of marketing medical
products. When we were unable to obtain suitable products, we ceased operations
and remained inactive from July 1985 until November 10, 1986, when we changed
our name to Immune Response, Inc. From November 1986 until May 1991, we were a
biomedical firm engaged in three levels of activity - clinical testing, clinical
research, and basic research.

         We operated the Clinical Testing and Research Division until May 1991,
when the Board of Directors, following an analysis of the results of the
Division's operations, determined that the operations were not commercially
viable and that it was highly unlikely the Division would ever be profitable.
Accordingly, on May 10, 1991, we entered into an Asset Purchase Agreement with
Infinity Laboratories, Inc. pursuant to which we sold to Infinity all of our
assets relating to our laboratory services. We suspended our biomedical
activities following this transaction and were inactive except for evaluating
alternative business opportunities.

         On January 8, 1996, we announced that we had executed an agreement to
merge with Ocurest Laboratories, Inc. of Palm Beach Gardens, Florida. Concurrent
with executing the merger agreement, we made a secured loan to Ocurest in the
amount of $125,000. On February 23, 1996, we announced the mutual termination of
our merger agreement. As part of the mutual termination agreement, Ocurest
repaid the aforementioned loan with interest. In addition, Ocurest agreed to pay
us a fee of $10,000, with interest, upon the successful completion of its
planned initial public offering which fee was paid during the fourth quarter of
1996.

         On February 10, 1997, at an Annual Meeting of Stockholders, our
stockholders approved a one-for-one hundred (1 for 100) reverse stock split
whereby every one hundred shares of our $.0001 par value common stock were
converted to one share of $.0001 par value common stock and approved a reduction
in the number of authorized shares from 950,000,000 to 25,000,000 effective
March 3, 1997. As a result, our issued shares were decreased from 312,470,000 to
3,124,700 and outstanding shares decreased from 294,970,000 to 2,949,700.

RECENT DEVELOPMENTS

         On December 9, 1999, we entered into an Agreement and Plan of
Reorganization with Opticon Acquisition Corporation, a Delaware corporation and
our wholly-owned subsidiary, and Opticon Medical, Inc., an Iowa corporation,
("Opticon Iowa"), providing for the merger of Opticon Iowa with and into Opticon
Acquisition Corporation.

         The stockholders of Opticon Iowa approved and adopted the Agreement and
Plan of Reorganization at a special meeting held on January 28, 2000. The merger
became effective February 25, 2000 and as a result, Opticon Acquisition
Corporation changed its name to Opticon Medical, Inc.

         At the effective date of the merger, each outstanding share of common
stock, no par value, Series A Preferred Stock, no par value, and Series B
Preferred Stock, no par value, of Opticon Iowa, totaling 4,482,906 shares and
held by approximately 88 shareholders, was converted into the right to receive
1.23 shares of Immune Response, Inc. common stock, $.0001 par value. A total of
5,513,974 Immune Response shares were issued in the merger. All shares issued in
the merger were issued pursuant to exemptions from registration under the
Securities Act of 1933. The merger consideration was determined based upon
arms-length negotiations between us and Opticon Iowa.

         As a result of the merger, all outstanding options, warrants, or other
purchase rights of Opticon Medical, Inc. were converted into the right to
receive the number of shares of our common stock as would have been issued or
delivered upon the exercise of such options, warrants and rights immediately
prior to the effectiveness of the merger. At the effective date of the merger,
there were outstanding an aggregate of 1,968,517 options and warrants, which by
reason of the merger may be exercised for approximately 2,421,276 shares of our
common stock.


                                      -14-
<PAGE>   17


         The transaction between us and Opticon Medical, Inc, was a business
combination between an operating enterprise (Opticon Medical, Inc.) and a "shell
company" (Immune Response, Inc.), in which we were the issuer of securities and
the operating enterprise was determined to be the acquiring enterprise for
financial reporting purposes. In this case, the business combination was being
treated for financial reporting purposes as an issuance of securities by Opticon
Medical, Inc. which has credited equity for the fair value of the tangible net
assets of Immune Response (i.e., no goodwill or intangible assets were
recognized in this transaction). Costs related to this transaction were charged
directly to equity.

         The historical financial statements of Opticon Iowa have been presented
as the historical financial statements of the combined enterprise and the assets
and liabilities of Immune Response were accounted for as required by the
purchase method of accounting without regard to which enterprise is the
surviving enterprise. The results of the operations of Immune Response are
included in the financial statements of the combined enterprise only from the
date of acquisition. The equity of Opticon Iowa has been presented as the equity
of the combined enterprise; however, the capital stock account of Opticon Iowa
has been adjusted to reflect the par value of our outstanding stock after giving
effect to the number of shares issued in the business combination. The
difference between the capital stock account of Opticon Iowa and our capital
stock account has been recorded as an adjustment to additional paid-in capital
of the combined enterprise. For periods prior to the business combination, the
equity of the combined enterprise is the historical equity of Opticon Iowa,
prior to the merger retroactively restated to reflect the number of shares
received in the business combination. The accumulated deficit of Opticon Iowa,
will be carried forward after the acquisition. Earnings (loss) per share for
periods prior to the business combination have been restated to reflect the
number of equivalent shares received by the shareholders of Opticon in the
merger.

         Immediately following the merger, we entered into Securities Purchase
Agreements with certain investors, whereby investors purchased $3 million in
principal amount of 6% convertible debentures and warrants to purchase 300,000
shares of our common stock at a price of $6.60 per share. The debentures were
convertible, either in whole or in part, into common shares, at any time at the
option of the holder, and from time to time, at a conversion price per share of
common stock equal to the lesser of: (a) $4.50 or (b) 65% of the market price of
our common stock. Any principal amount of debentures outstanding on the third
anniversary of the issuance were automatically convertible into common stock at
the conversion price unless the common stock issuable on such conversion would
exceed 19.99% of the common stock outstanding on the mandatory conversion date,
in which case our shareholders would have to approve the issuance of the common
stock in excess of the 19.99% threshold. In the event of no shareholder
approval, any unconverted portion of the debentures were required to be redeemed
for cash.

         The debentures were recorded at the amount of gross proceeds of $3
million, less the fair value of the warrants, which were valued at $775,000. The
calculated conversion price at February 25, 2000, the first available conversion
date, was $2.93 per share. In accordance with the FASB's Emerging Issues Task
Force Issue 98-5, the difference between this conversion price and the market
price of $4.50 per share was reflected as additional interest expense of
$1,613,013 in the combined company's statement of operations for the quarter
ended March 31, 2000.

         On March 17, 2000, the debentures were exchanged for 3,000 shares of
Series A 6% Convertible Preferred Stock. The preferred stock has identical terms
and conditions to the debentures, except that the holders of preferred stock are
entitled to cumulative dividends rather than interest, payable quarterly in cash
or common stock. At the time of conversion, the principal balance of the
debentures was $2,246,528, and accrued interest was $9,250. On the conversion
date, we also netted the deferred debt issuance costs of $440,159, previously
recorded as an asset, with the carrying value of the preferred stock. The
dividends were accrued at June 30, 2000, in the amount of $51,781.

         On July 27, 2000, Immune Response merged into its wholly-owned
subsidiary, Opticon Medical, Inc., a Delaware corporation. The merger was
approved at our Annual Meeting of Shareholders and became effective on July 27,
2000. As a result, our corporate structure was consolidated into a single entity
domiciled in Delaware, and began trading under the new symbol "OPMI" on the OTC
Bulletin Board. We continue our operations as a development stage enterprise
formed to develop, manufacture, and market disposable devices for use in urology
and for the management and control of the symptoms of urinary incontinence in
adults. Our current focus is on the development activities and regulatory
approval process relating to its initial product, the OPTICON(TM) , a
disposable, silicone indwelling valved catheter, to be first indicated for use
in acute, short-term urinary management.


                                      -15-
<PAGE>   18

         At the effective date of the merger, each outstanding share of common
stock of Immune Response was converted automatically into one share of our
common stock, par value $0.0001 per share, and each outstanding share of Immune
Response preferred stock was converted into one share of our Series A, 6%
Convertible Preferred Stock, par value $0.0001 per share.

         All outstanding options, warrants and other rights to purchase Immune
Response common stock were converted into options, warrants or rights to
purchase the same number of shares of Opticon Medical common stock.

OVERVIEW

         Our current business began in 1994, as an Iowa corporation formed to
develop, manufacture, and market a series of innovative, proprietary,
cost-effective, disposable devices designed to manage and control the symptoms
of urinary incontinence in adults. Urinary incontinence, the involuntary loss of
urine, affects an estimated 18 million people in the United States, the vast
majority of which are female. Urinary incontinence can be an intrusive,
debilitating, and embarrassing condition that has a significant impact on a
patient's quality of life. Our founder, Fouad A. Salama, M.D., conceived,
produced, and tested a series of devices which showed promise for treating
individuals suffering from urinary incontinence, and his efforts ultimately
resulted in the OPTICON(TM) device and its associated patents, which formed the
basis of our business. We have recently relocated to Dublin, Ohio, and are
preparing to enter into the commercialization phase of business development.

         Our initial product is the OPTICON(TM), a disposable, silicone,
indwelling valved catheter designed to manage urinary incontinence in females.
We have also developed the OPTICON(TM) Direct, a non-valved, continuous drainage
device to be used in the same manner as a Foley catheter. Because of the greater
innovation and distinct value of the OPTICON(TM) (valved) device, we intend to
market the OPTICON(TM) Direct on an opportunistic basis and only after the
OPTICON(TM) has been introduced commercially. We have developed prototypes of
male versions of the devices as well. We believe that the OPTICON(TM) device
represents a whole new modality in the management of urinary incontinence,
particularly for the moderate-to-severely incontinent patient who fails to be
satisfied by wearing absorbent pads or adult diapers, or for whom specific
surgical remedies or other treatments are not available. Additionally, early
clinical trial experience has suggested that our technology will have
applications within the short-term urinary management market as well. The
OPTICON(TM) is more functional than urethral plugs or patches and more
convenient than traditional Foley catheters. Individuals using the OPTICON(TM)
will remain dry and odor free and better able to engage in normal life
activities with reduced fear and embarrassment.

         We expect to initially use a contract manufacturer to produce the
OPTICON(TM) and are pursuing arrangements with various vendors for different
phases of manufacturing, including tooling, component parts assembly,
sterilization, and packaging. We plan to market the products in the United
States using multiple distribution channels, including a direct sales force and
alliances with major health care companies. We also expect to develop
distribution relationships and corporate alliances for international
distribution.

          Prior to the merger, we had had no sales, generated no revenues, and,
until the completion of the financing, have operated as a "virtual corporation"
by combining the contributions of a small number of direct full-time employees
with the services of a host of third-party contractors. We intend to apply
working capital toward more fully establishing its directly employed
infrastructure, completing its clinical trials for short-term use of the valved
device, further progressing its product development projects, and establishing
its initial market channels. We will continue to outsource expertise in the
legal and financial disciplines and expect to continue with contract
manufacturing at least through the first two years of market experience.

MARKET AND COMPETITIVE BUSINESS CONDITIONS

         We believe that our principal competition will come initially from
existing urinary incontinence products, such as adult diapers and absorbents,
with additional competition from existing catheters and surgical products. Also,
pharmaceutical products have been introduced which have been shown to have a
certain effectiveness for urge incontinence. Procter & Gamble, Kimberly-Clark,
PMP, Inc., and Johnson & Johnson lead the market for diapers


                                      -16-
<PAGE>   19

and pads. The urological division of C.R. Bard is the market leader for current
indwelling catheters and supply products, holding over 50% of the market through
its branded and original equipment manufactured product lines. Other significant
participants in this market include Hollister, Sherwood, Rusch, Kendall, and
Mentor. Their primary market thrust continues to be in the area of traditional
urinary management. Bard also leads the United States market for bulking agents
with Contigen(TM), a collagen-based material which is injected into the
pertinent tissues for Intrinsic Sphincter Deficiency related incontinence.

         We believe that we are well positioned to ultimately compete within a
total domestic market that currently exceeds $1.2 billion annually. We estimate
similarly sized opportunities in markets overseas.

GOVERNMENTAL REGULATIONS

         Government regulation in the United States and other countries is a
significant factor in the development and marketing of our products and in our
ongoing manufacturing and research and development activities. We and our
products are subject to regulation by numerous governmental authorities,
primarily the United States Food and Drug Administration and corresponding
foreign agencies, under a number of statutes including the Food, Drug and
Cosmetic Act, as amended. Manufacturers of medical devices must comply with
applicable provisions and associated government regulations governing the
development, testing, manufacturing, labeling, marketing, and distribution of
medical devices and the reporting of certain information regarding their safety.
The FDC Act requires certain clearances from the FDA before medical devices,
such as the OPTICON(TM), can be marketed.

         In August 1996, we received 510(k) allowance from the FDA to market the
OPTICON(TM) Direct as a drainage device. We expect to obtain FDA 510(k)
allowance and to have the OPTICON(TM) (valved) product market-ready for
short-term use, and plan to enter the market for short-term urinary management
for indications requiring use for 14 or fewer days. Thereafter, we intend to
seek an Investigational Device Exemption to permit clinical trials regarding
chronic use of the OPTICON(TM) and then file a Pre-Market Approval application
to obtain approval to market the OPTICON(TM) for chronic use in the United
States. The process for a Pre-Market Approval application often takes in excess
of 2 1/2 years, including the clinical trial process and subsequent
consideration from the FDA. In addition, we intend to seek ISO and CE mark
certification, which will facilitate the marketing of the OPTICON(TM) in Europe.

         Conducting the clinical trials to support a 510(k) submission for
short-term urinary management is the primary objective in regulatory affairs. A
trial protocol has been drafted and will be brought to final form with
assistance from our previously assembled network of clinical investigators,
after which we will collaborate with the FDA to gain agreement to proceed to
trial. A meeting with FDA is now scheduled for early September. We believe that
a statistically valid sampling of patients can be studied over a relatively
short 4-5 month time frame once the Institutional Review Boards of each of our
investigative sites grant their approval to proceed. Assuming trial results
remain satisfactory, we expect to have made our submission to the FDA before the
end of the first quarter of 2001. Within that period of time, it is also our
goal to have essentially completed the process necessary to apply for the
European CE marking - the regulatory requirement for entering major foreign
markets.

PATENTS AND TRADEMARKS

         Following the initial research and development of our core technology,
an initial United States patent was issued in 1990 relating to the one-way
disposable urinary control valve. Several subsequent patents and patent
extensions have been issued, the most recent of which was in December 1997, and
notice of allowance for claims relating to a new discharge valve was received in
March 1998. Patents relating to this core technology have also been issued in
Canada, Australia, Japan, North Korea, South Korea, and a number of countries
throughout Europe, including those countries participating in the Patent
Cooperation Treaty.

         Issued patent claims apply to the proprietary shape of the retention
balloon and to the method for adjusting length and anchoring the device in
place. The design and function of the discharge valve is also patented.
Continuing development has resulted in additional patent applications, and in
April 1999, a new patent was issued for a surgically implantable artificial
sphincter. We originally acquired an exclusive and irrevocable license to the


                                      -17-
<PAGE>   20

OPTICON(TM) and its related technology from Dr. Salama. In 1997, we entered into
an ongoing exclusive consulting agreement with Dr. Salama, wherein Dr. Salama
assigned ownership of all existing patents, and will assign all future patents
he develops in the fields of urology, urogynecology, and urinary incontinence
care, directly to us.

EMPLOYEES

         As of August 22, 2000, we employed 5 full time employees and used the
services of several external consultants. None of our employees are subject to a
collective bargaining agreement, and we consider our relationships with our
employees to be good.

PROPERTIES

         We lease approximately 4,100 square feet of space at 7001 Dublin Road,
Suite 100, Dublin, Ohio 43016, at an annual net rent of $58,997, under a lease
that expires on September 30, 2001.

          year end ($0.39 on December 31, 1999). An option is in-the-money if
          the fair market value of the underlying shares exceeds the exercise
          price of the option.

EMPLOYMENT AGREEMENTS

         In March 1997, we entered into an employment agreement with Mr. Post,
which provides, among other things, for a salary of $160,000, payment of bonus
compensation upon achievement of certain milestones, grant of an option to
purchase 250,000 shares of our common stock, indemnification for certain
breaches of his fiduciary duty as a director, continuation of his then current
base salary for a period of 12 months (or such lesser period until he finds
other full-time employment) if we terminate his employment without "cause" (as
such term is defined in such agreement), and a covenant not to compete and not
to solicit our employees during the term of his employment and for two years
following the termination of his employment for any reason. Such employment
agreement has an initial term of two years and is automatically extended for
successive one year periods unless either party objects to such extension at
least 30 days prior to the end of the initial term or any extension term. In
light of our limited financial resources, we amended such employment agreement
in February 1998 to defer Mr. Post's unpaid bonuses earned in 1997 and 1998,
which deferred amount accrued interest at a rate of 10%. The deferrals continued
in 1999. In March 2000, we paid the deferrals with interest.

         In September 1997, we entered into an employment agreement with Mr.
LaMarche, which agreement provides, among other things, for a salary of
$100,000, indemnification for certain breaches of his fiduciary duty as a
director, continuation of his then current base salary for a period of four
months (or such lesser period until he finds other full-time employment) if we
terminate his employment without "cause" (as such term is defined in such
agreement), and a covenant not to compete and not to solicit our employees
during the term of his employment and for two years following the termination of
his employment for any reason. Such employment agreement had an initial term
ending December 31, 1997, but is automatically extended for successive one year
periods unless either party objects to such extension at least 30 days prior to
the end of any extension term. In light of our limited financial resources, such
employment agreement was amended in February 1998 to defer 27% of Mr. LaMarche's
1998 salary, which deferred amount accrued interest at a rate of 10%. The
deferrals continued in 1999. In March 2000, the deferrals were paid with
interest.

         In November 1997, we entered into a four-year consulting agreement with
Dr. Salama, pursuant to which Dr. Salama agreed to render his exclusive
developmental services and design expertise in the areas of urology,
urogynecology and incontinence care. In return for his services, Dr. Salama
received $110,000 per year for the first two years of the agreement and will
receive $75,000 per year for the remaining two years as well as reasonable and
necessary out-of-pocket expenses. The consulting agreement also provides that
Dr. Salama will assign directly to us all future patents developed during the
consulting period or within one year thereafter and relating to our business. In
connection with the consulting agreement, we also entered into an agreement with
Dr. Salama, providing, among other things, for (i) assignment to us of all of
Dr. Salama's existing patents relating to our business, (ii) continuation and
extension of certain benefits and stock options, (iii) mutual release of claims,
and (iv) a two-year noncompetition agreement.

                             PRINCIPAL STOCKHOLDERS

         The following table provides information regarding the beneficial
ownership of our common stock as of August 22, 2000 by:

         - each stockholder known by us to be the beneficial
           owner of more than 5% of our common stock;

         - each director;

         - the named executive officer; and

         - all directors and executive officers as a group.

         We have determined beneficial ownership in accordance with the rules of
the Securities and Exchange Commission. Unless otherwise indicated, the persons
and entities included in the table have sole voting and investment power with
respect to all shares beneficially owned, subject to applicable community
property laws. Shares of our common stock subject to options that are either
currently exercisable or exercisable within 60 days of August 22, 2000, are
treated as outstanding and beneficially owned by the option holder for the
purpose of computing the percentage ownership of the option holder. However,
these shares are not treated as outstanding for the purpose of computing the
percentage ownership of any other person.

                           RELATED PARTY TRANSACTIONS

         On November 29, 1999, Opticon Medical, Inc., the Iowa corporation,
issued a Promissory Note to us for the sum of $100,000. The loan was made for
the purpose of covering Opticon Medical, Inc., the Iowa corporation's operating
expenses pending the merger. We financed the loan through our Private Placement
Offering in November 1999. We settled the Promissory Note, together with accrued
interest at a rate of 8.5%, as part of the merger.

                          DESCRIPTION OF CAPITAL STOCK

         The following brief description of certain provisions of our Conformed
Certificate of Incorporation and Amended and Restated Bylaws does not purport to
be complete and is subject in all respects to the provisions of the Certificate
and Bylaws, copies of which have been filed as exhibits to the registration
statement of which this prospectus is a part.

         Our authorized capital stock consists of 25,000,000 shares of common
stock, $0.0001 par value, and 1,000,000 shares of preferred stock, $0.0001 par
value. There are currently outstanding 7,691,762 shares of common stock, and
3,000 shares of preferred stock. All outstanding shares of common stock are
fully paid and non-assessable.

COMMON STOCK

         Holders of validly issued and outstanding shares of common stock are
entitled to one vote per share of record on all matters to be voted upon by
stockholders. At a meeting of stockholders at which a quorum is present, a
majority of the votes cast decides all questions, unless the matter is one upon
which a different vote is required by express provision of law or our
Certificate or Bylaws. Our Certificate does not provide stockholders the right
to cumulate their votes in the election of directors. As a result, holders of
more than 50% of the outstanding shares can elect all of our directors.
Stockholders have no preemptive or other rights to subscribe for additional
shares nor any other rights to convert their common stock into any other
securities.

         Subject to the preferences that may be applicable to the holders of any
outstanding shares of preferred stock, holders of common stock are entitled to
such dividends as may be declared by the Board of Directors out of funds legally
available therefor. The payment by us of dividends, if any, rests within the
discretion of our Board of Directors and will depend upon our operating results,
financial condition and capital expenditure plans, as well as other factors
considered relevant by the Board of Directors. Upon our liquidation, dissolution
or winding-up, the assets legally available for distribution to stockholders are
distributable ratably among the holders of common stock at that time
outstanding, subject to prior distribution rights of our creditors and
preferential rights of any outstanding shares of preferred stock.

PREFERRED STOCK

          Our Certificate authorizes the Board of Directors to issue up to
1,000,000 shares of preferred stock in one or more series and to establish such
relative dividend, redemption, liquidation, conversion and other powers,
preferences, rights, qualifications, limitations and restrictions as the Board
of Directors may determine without further approval of our stockholders. The
issuance of preferred stock by the Board of Directors could be used, under
certain circumstances, as a method of delaying or preventing a change in control
and could permit the Board of Directors, without any action by holders of common
stock, to issue preferred stock which could have a detrimental effect on the
rights of holders of common stock, including loss of voting control. In certain
circumstances, this could have the effect of decreasing the market price of the
common stock.

         The issuance of any series of preferred stock, and the relative powers,
preferences, rights, qualifications, limitations and restrictions of such
series, if and when established, will depend upon, among other things, our
future capital needs, the then-existing market conditions and other factors
that, in the judgment of the Board of Directors, might warrant the issuance of
preferred stock.

SERIES A, 6% CONVERTIBLE PREFERRED STOCK

         On February 24, 2000, the directors authorized the designation of 3,000
shares of preferred stock as the "Series A, 6% Convertible Preferred Stock".
These shares were issued pursuant to an Exchange Agreement between us and the
selling stockholders whereby the selling stockholders received an equal number
of preferred stock for their interests in the debentures. See "Selling
Stockholders."

         Each share of preferred stock has a stated value of $1,000 and is
entitled to receive dividends at a rate of six (6%) percent per annum of the
stated value per share thereof. Dividends are cumulative from the date of issue,
whether or not declared for any reason and whether or not there are funds
legally available for the payment thereof. Each dividend is payable at our
option, in common stock or cash on a pro rata basis, in equal quarterly amounts
on each March 31, June 30, September 30 and December 31 of each year the Series
A Preferred Stock is outstanding, beginning on June 30, 2000.

         Except as otherwise provided by the Delaware General Corporation Law,
the holders of the preferred stock have no voting rights.

         The shares of preferred stock are convertible at any time into shares
of common stock, at a price equal to the lesser of: (a) $4.50 and (b) 65% of the
average of the closing bid prices of the common stock as reported by the OTC/BB
for the five (5) consecutive trading days immediately prior to conversion,
subject to adjustment for certain events. We will mandatorily convert the
preferred shares into common stock on February 25, 2003.


WARRANTS

         We issued to the selling stockholders warrants to purchase 300,000
shares of our common stock. They are exercisable by the selling stockholders at
any time until February 28, 2005, at a purchase price equal to $6.60 per share.

         The warrants issued to the selling stockholders contain provisions that
protect the holder against dilution by adjustment of the exercise price and
number of shares to be received upon exercise. Adjustments will occur in the
event, among others, of a merger, stock split or reverse stock split, stock
dividend or recapitalization. We are not required to issue fractional shares
upon the exercise of the warrants. The holder of the warrants will not possess
any rights as a stockholder until the holder exercises the warrants.

         The warrants may be exercised upon surrender on or before the
expiration date of the warrants at our offices, with an exercise form completed
and executed as indicated, accompanied by payment of the exercise price for the
number of shares for which the warrant is being exercised. The exercise price is
payable by check or bank draft payable to our order or by wire transfer.

         For the life of the warrants, the holder has the opportunity to profit
from a rise in the market price of the common stock without assuming the risk of
ownership of the shares of common stock issuable upon the exercise of the
warrant. The warrant holder should be expected to exercise the warrant at a time
when we would likely be able to obtain any needed capital by an offering of
common stock on terms more favorable than those provided for by the warrant.
Furthermore, the term on which we could obtain additional capital during the
life of the warrant may be adversely affected.

TRANSFER AGENT

         The Transfer Agent and registrar for our common stock is Corporate
Stock Transfer, Inc., Denver, Colorado.

CERTAIN PROVISIONS OF OUR ARTICLES AND BYLAWS

STOCKHOLDER ACTION BY WRITTEN CONSENT

                                      -27-
<PAGE>   30


         Our Bylaws provide that any action that may be taken at a meeting of
our stockholders may be taken without a meeting if such action is authorized by
the unanimous written consent of all stockholders entitled to vote at a meeting
for such purposes. Since we have numerous stockholders, it is not likely that
action by unanimous written consent of the stockholders is feasible.


SPECIAL MEETINGS

         Our Bylaws provide that special meetings of our stockholders may be
called by the Board, by our President or by one or more written demands for the
meeting, stating the purposes for which it is to be held, signed and dated by
the holders of shares representing at least 10 percent of all the votes entitled
to be cast on any issue proposed to be considered at the meeting. This
provisions may make it difficult for stockholders to take action opposed by the
Board.

AMENDMENTS TO OUR BYLAWS

         Our Bylaws provide that they may be amended or repealed by the
stockholders or, except to the extent limited by Delaware law, by the Board of
Directors.

INDEMNIFICATION

         Our directors and officers are entitled to statutory rights to be
indemnified by us against litigation-related liabilities and expenses if the
director or officer is either successful in the defense of litigation or is
otherwise not to have engaged in willful misconduct, knowingly violated the law,
failed to deal fairly with us or our stockholders or derived an improper
personal benefit in the performance of his duties to us. These rights are
incorporated in our Certificate and Bylaws. Insofar as indemnification for
liabilities arising under the Securities Act may be permitted to our directors,
officers, and controlling persons, we have been advised that in the opinion of
the Securities and Exchange Commission, such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities, other than
the payment by us of expenses incurred or paid by our directors, officers or
controlling persons in connection with any securities being registered, we will,
unless in the opinion of counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question of whether
such indemnification by us is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issues.

                              SELLING STOCKHOLDERS

         The 5,455,385 shares of our common stock described in this prospectus
includes 4,615,385 shares which may be issued to the selling stockholders upon
exchange of their preferred stock, 540,000 shares which may be issued as payment
for dividends on the preferred stock, plus 300,000 shares which may be issued
upon exercise of their warrants. Except for the ownership of the preferred stock
and the warrants (and any shares upon conversion or exercise thereof), the
selling stockholders have not had a material relationship within the past three
years with us. The shares of common stock are being registered to permit public
secondary trading of the shares, and the selling stockholders may offer the
shares for resale from time to time. See "PLAN OF DISTRIBUTION."

         The warrants were issued by us in February 2000, and are exercisable at
a price equal to $6.60 per share. Pursuant to an Exchange Agreement between us
and the selling stockholders, the preferred stock was issued in exchange for
certain debentures issued by us in February 2000. The preferred stock and any
dividends accrued thereon may be converted into common stock at any time. The
preferred stock is entitled to cumulative annual dividends at the rate of 6% of
stated value payable in common stock at the time of each conversion, and is
convertible into shares of our common stock based on the conversion price at the
time of conversion. The conversion price is an amount equal to the lesser of (a)
$4.50 and (b) 65% of the average of the closing bid prices of the common stock
for the five business days prior to conversion. The conversion price is subject
to equitable adjustment upon the occurrence of certain events, such as stock
splits, stock dividends, reclassifications or combinations.

         A selling stockholder is prohibited from converting any portion of the
preferred stock which would result in the selling stockholder being deemed the
beneficial owner, in accordance with the provisions of Rule 13d-3 under the
Exchange Act, of 5.00% or more of the then issued and outstanding common stock.

                  As required by the Exchange Agreement and related Registration
Rights Agreement, in recognition of the fact that selling stockholders may wish
to be legally permitted to sell any shares of common stock acquired upon
conversion of the preferred stock or exercise of the warrants, or received as
payment for dividends on the preferred stock when they deem appropriate, we have
filed with the Commission under the Securities Act a registration statement on
Form SB-2, of which this prospectus forms a part, with respect to the resale of
the shares of common stock by the selling stockholders from time to time on the
OTC Bulletin Board or in privately-negotiated transactions.

entitled to acquire upon conversion of the preferred stock, assuming a market
price upon conversion of $1.64 per share, and upon exercise of the warrants. The
selling stockholders currently beneficially own approximately 3,134,093 shares
in the aggregate, but the actual number of shares which may be beneficially
owned by them on any future date will depend on the aggregate principal amount
of preferred stock then outstanding, the conversion price(s) on the date(s)
preferred stock has been converted, and the number of shares of our common stock
which have previously been sold by them pursuant to this registration statement.

conversion of the preferred stock and 150,000 shares that would be held upon
exercise of the warrants. As of the date of this prospectus, Shaar has converted
85 shares of preferred stock into 99,572 shares of common stock.

(3) Includes 938,086 shares of common stock which would be held upon conversion

                              PLAN OF DISTRIBUTION

         Although we have not been advised of any selling stockholders' plans to
do so, the selling stockholders may sell the shares from time to time in
transactions in over-the-counter transactions reported on the OTC Bulletin
Board, in negotiated transactions, or otherwise, or by a combination of these
methods, at fixed prices which may be changed, at market prices at the time of
sale, at prices related to market prices or at negotiated prices. A selling
stockholder shall have the sole and absolute discretion not to accept any
purchase offer or make any sale of shares if it deems the purchase price to be
unsatisfactory at any particular time. The selling stockholders may effect these
transactions by selling the shares to or through broker-dealers, who may receive
compensation in the form of discounts, concessions or commissions from the
selling stockholders or the purchasers of the shares for whom the broker-dealer
may act as an agent or to whom they may sell the shares as a principal, or both.
The compensation to a particular broker-dealer may be in excess of customary
commissions.

         Broker-dealers who act in connection with the sale of the shares may be
underwriters. Profits on any resale of the shares as a principal by such
broker-dealers and any commissions received by such broker-dealers may be
underwriting discounts and commissions under the Securities Act.

         Any broker-dealer participating in transactions as agent may receive
commissions from a selling stockholder and, if they act as agent for the
purchaser of the shares, from the purchaser. Broker-dealers may agree with a
selling stockholder to sell a specified number of shares at a stipulated price
per share and, to the extent a broker-dealer is unable to do so acting as agent
for the selling stockholder, to purchase as principal any unsold shares at a
price required to fulfill the broker-dealer commitment to the selling
stockholder. Broker-dealers who acquire shares as a principal may resell the
shares from time to time in transactions (which may involve crosses and block
transactions and which may involve sales to and through other broker-dealers,
including transactions of the nature described above) in the over-the-counter
market, in negotiated transactions or otherwise at market prices prevailing at
the time of sale or at negotiated prices, and may pay to or receive from the
purchasers of the shares commissions computed as described above. To the extent
required under the Securities Act, a supplemental prospectus will be filed,
disclosing:

         - the name of the broker-dealers;

         - the number of shares involved;

         - the price at which the shares are to be sold;

         - the commissions paid or discounts or concessions
           allowed to the broker-dealers, where applicable;

         - that broker-dealers did not conduct any investigation to
           verify the information in this prospectus, as supplemented; and

         - other facts material to the transaction.

         Under applicable rules and regulations under the Exchange Act, any
person engaged in a distribution of the shares may not simultaneously engage in
market making activities with the common stock for a period beginning when the
person becomes a distribution participant and ending upon the person's
completion of participation in a distribution, including stabilization
activities in the common stock to effect covering transactions, to impose
penalty bids or to effect passive market making bids. In addition, we and the
selling stockholders will be subject to applicable provisions of the Exchange
Act, including Rule 10b-5 and to the extent we and the selling stockholders are
distribution participants, Regulation M. These rules and regulations may affect
the marketability of the shares.

         The selling stockholders will pay any commissions associated with the
sale of the shares. The shares offered by this prospectus are being registered
to comply with contractual obligations, and we have paid the expenses of the
preparation of this prospectus. We have also agreed to indemnify the selling
stockholders against liabilities, including liabilities under the Securities
Act, or, if the indemnity is unavailable, to contribute toward amounts required
to be paid the liabilities.


                                  LEGAL MATTERS

         The validity of the shares offered hereby has been passed upon for us
by Porter, Wright, Morris & Arthur LLP, 41 South High Street, Columbus, Ohio
43215.

                                     EXPERTS

         The financial statements of Opticon Medical, Inc. (f/k/a Immune
Response, Inc.)(a development stage enterprise) as of December 31, 1999, and for
the year ended December 31, 1999 and the period from May 14, 1984 (inception) to
December 31, 1999, included herein and elsewhere in the registration statement
have been audited by KPMG LLP, independent certified public accountants. Such
financial statements have been included herein and in the registration statement
in reliance upon the report of KPMG LLP, appearing elsewhere herein, and upon
the authority of said firm as experts in accounting and auditing.



         The cumulative statements of operations, stockholders' equity, and cash
flows for the period May 14, 1984 (inception) to December 31, 1999 include
amounts for the period from May 14, 1984 (inception) to December 31, 1998 and
for the year ended December 31, 1998, which were audited by other auditors whose
report has been furnished to KPMG LLP, and KPMG LLP's opinion, insofar as it
relates to the amounts included for the period May 14, 1984 through December 31,
1998 is based solely on the report of the other auditors.


         The report of KPMG LLP covering the December 31, 1999, financial
statements contains an explanatory paragraph that states that the Company's
recurring losses from operations raise substantial doubt about the entity's
ability to continue as a going concern. The financial statements do not include
any adjustments that might result from the outcome of that uncertainty.

                  CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS
                     ON ACCOUNTING AND FINANCIAL DISCLOSURE

         On November 2, 1999, we dismissed Davis & Co., CPA's, P.C. as our
independent certified public accountant. There have been no adverse opinions,
disclaimers of opinion or qualifications or modifications as to audit scope or
accounting principles regarding the reports of Davis on our financial statements
for each of the fiscal years ended December 31, 1998 and 1997, or any subsequent
interim period. Our Board of Directors approved the change of accountants and
that action was ratified by our Board of Directors as we had no formal audit
committee.

         For the fiscal years ended December 31, 1998 and 1997, the auditors
report contained a qualification as to uncertainty which read as follows:


                                      -32-
<PAGE>   35

         "The accompanying financial statements have been prepared assuming that
the Company will continue as a going concern. As discussed in Note 8, the
Company has minimal capital resources presently available to meet obligations
which normally can be expected to be incurred by similar companies, and has
accumulated deficit of ($924,145) at December 31, 1998. These factors raise
substantial doubt about the Company's ability to continue as a going concern.
Management's plans in regard to these matters are also described in Note 8. The
financial statements do not include any adjustments that might result from the
outcome of this uncertainty."

         Simultaneously with the dismissal of Davis, we approved and engaged
Gelfond Hochstadt Pangburn, P.C. to act as our independent certified public
accountant as successor to Davis. During our fiscal years ended December 31,
1998 and 1997, or subsequent interim period, we had not consulted with Gelfond
regarding the application of accounting principles to a specified transaction,
either completed or proposed, or the type of audit opinion that might be
rendered on our financial statements, or any other matter that was the subject
of disagreement or a reportable condition.

         On March 13, 2000, we dismissed Gelfond as our independent certified
public accountant. Gelfond has not issued any opinions on our financial
statements, and, therefore, there have been no adverse opinions, disclaimers of
opinion or qualifications or modification as to audit scope or accounting
principles regarding any report of Gelfond on our financial statements. Our
Board of Directors approved the change of accountants and that action was
ratified by our Board of Directors. There were no disagreements with Gelfond on
any matter of accounting principles or practices, financial statement
disclosure, or auditing scope of procedures leading to their dismissal. The
dismissal is a result of the change of the our Board of Directors and the moving
of our principal office to Dublin, Ohio, as a result of our merger with Opticon
Medical.

         Simultaneously with the dismissal of our former accountants, we
approved and engaged KPMG LLP to act as our independent certified public
accountant as successor to Gelfond. During our two most recent fiscal years and
subsequent interim periods we have not consulted with KPMG regarding the
application of accounting principles to a specified transaction, either
completed or proposed, or the type of audit opinion that might be rendered on
the our financial statements, or any matter that was the subject of a
disagreement or a reportable condition.

         There were no reportable conditions, in each case, during either of our
two most recent fiscal years or any subsequent interim period.

                          INDEPENDENT AUDITORS' REPORT



     The Board of Directors and Stockholders
     Immune Response, Inc.:

     We have audited the accompanying balance sheet of Immune Response, Inc. (a
     development stage enterprise) as of December 31, 1999, and the related
     statements of operations, stockholders' equity and comprehensive income,
     and cash flows for year ended December 31, 1999 and for the period from May
     14, 1984 (inception) to December 31, 1999. 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 audit. The
     cumulative statements of operations, stockholders' equity, and cash flows
     for the period May 14, 1984 (inception) to December 31, 1999 include
     amounts for the period from May 14, 1984 (inception) to December 31, 1998
     and for the year ended December 31, 1998, which were audited by other
     auditors whose report has been furnished to us, and our opinion, insofar as
     it relates to the amounts included for the period May 14, 1984 through
     December 31, 1998 is based solely on the report of the other auditors.

     We conducted our audit 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 audit
     provides a reasonable basis for our opinion.

     In our opinion, based on our audit and the report of the other auditors,
     the financial statements referred to above present fairly, in all material
     respects, the financial position of Immune Response, Inc. (a development
     stage enterprise) as of December 31, 1999, and the results of its
     operations and its cash flows for each of the year ended December 31, 1999
     and for the period May 14, 1984 (inception) to December 31, 1999, in
     conformity with generally accepted accounting principles.

     The accompanying financial statements have been prepared assuming that the
     Company will continue as a going concern. As discussed in Note 6 to the
     financial statements, the Company has suffered recurring losses from
     operations that raise substantial doubt about its ability to continue as a
     going concern. The financial statements do not include any adjustments that
     might result from this uncertainty.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

To the Board of Directors
Immune Response, Inc.

We have audited the accompanying statements of operations, changes in
stockholders' equity (deficit) and cash flows of Immune Response, Inc. (a
development stage company) for the year ended December 31, 1998, and for the
period from inception (May 14, 1984) to December 31, 1998. 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, the financial statements referred to above present fairly, in
all material respects, the results of operations and cash flows of Immune
Response, Inc. (a development stage company) for the year ended December 31,
1998, and for the period from inception (May 14, 1984) to December 31, 1998, in
conformity with generally accepted accounting principles.

The accompanying financial statements referred to above have been prepared
assuming that the Company will continue as a going concern. The Company has
minimal capital resources presently available to meet obligations which normally
can be expected to be incurred by similar companies, and has an accumulated
deficit of ($924,145) at December 31, 1998. These factors raise substantial
doubt about the Company's ability to continue as a going concern. The Company
has no significant fixed commitments as of December 31, 1998 or March 23, 1999.
Management believes that the remaining minimal cash flow requirements needed to
pursue potential mergers or other business opportunities can be met through use
of the Company's current cash balance and additional sales of IntraNet stock.
The financial statements do not include any adjustments that might result from
the outcome of this uncertainty.

                              IMMUNE RESPONSE, INC.
                        (A development stage enterprise)

                          Notes to Financial Statements


1.      NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

         (a)  NATURE OF BUSINESS

              Immune Response, Inc. (the Company) was incorporated under the
              laws of the State of Colorado on May 14, 1984 as Med Mark
              Technologies, Inc. and was inactive during the period from July 1,
              1985 to November 9, 1986. On November 10, 1986, the Company
              changed its name to Immune Response, Inc. and resumed its
              organizational activities.

              Until the Company sold its laboratory assets in May 1991, the
              Company performed research and provided testing facilities for
              disorders of the immune system. Although the Company received
              laboratory test income and revenue from the sale of marketing
              rights in 1990 and early 1991, the amounts received were minimal
              and did not represent revenues from the Company's principal
              planned line of business. The Company has been inactive since the
              sale of its lab assets in May 1991. The Company's Directors do
              maintain some minimal level of activity which is performed at
              another entity affiliated with the Directors. The Company
              reimburses the affiliated entity for these activities. These
              amounts are included in accounts payable to related parties in the
              accompanying balance sheet. The Company also owes $22,453 in
              accrued interest to this entity.

              The accompanying financial statements have been prepared on the
              basis that the Company will continue as a going concern, which
              contemplates the realization of assets and satisfaction of
              liabilities in the normal course of business. The Company has
              incurred operating losses in each period since inception. There is
              no assurance that the Company will be profitable in the future.

        (b)   CASH AND CASH EQUIVALENTS

              Cash equivalents consist of money market funds. For purposes of
              the statement of cash flows, the Company considers all highly
              liquid debt instruments with original maturities of three months
              or less to be cash equivalents.

         (c)  INVESTMENT SECURITIES

              Investment securities at December 31, 1999 consist of equity
              securities. The Company classifies its equity securities as
              available-for-sale. These securities are recorded at fair value.
              Unrealized holding gains and losses on available for sale
              securities are excluded from earnings and are reported as a
              separate component of other comprehensive income until realized.
              Realized gains and losses from the sale of available-for-sale
              securities are determined on a specific identification basis.

              A decline in the market value of available-for-sale securities
              below cost that is deemed to be other than temporary results in a
              reduction in carrying amount to fair value. The impairment is
              charged to earnings and a new cost basis for the security is
              established. Dividend income is recognized when earned.

                          Notes to Financial Statements


         (d)  USE OF ESTIMATES

              The preparation of financial statements in conformity with
              generally accepted accounting principles requires management to
              make estimates and assumptions that affect the reported amounts of
              assets and liabilities and disclosure of contingent assets and
              liabilities at the date of financial statements and the reported
              amounts of revenues and expenses during the reporting period.
              Actual results could differ from those estimates.

         (e)  FINANCIAL INSTRUMENTS

              At December 31, 1999 and 1998, the financial statement carrying
              amounts of cash and cash equivalents, current assets, current
              liabilities and current notes receivable approximated the fair
              value of these instruments because of the short-term maturity of
              these instruments. The fair value of investment securities are
              based on quoted market prices at the reporting date for those
              investments.

        (f)   RECENT ACCOUNTING PRONOUNCEMENTS

              The Company adopted the provisions of Statement of Financial
              Accounting Standards "(SFAS") No. 130, "Reporting Comprehensive
              Income" in 1998. SFAS No. 130 requires the Company to report in
              its financial statements, in addition to its net loss,
              comprehensive income (loss), which includes all changes in equity
              during a period from non-owner sources including, as applicable,
              foreign currency items, minimum pension liability adjustments and
              unrealized gains and losses on certain investments in debt and
              equity securities. During 1999, the Company had unrealized holding
              gains of $33,055, less a reclassification adjustment for gains
              realized in income $19,564.

              In June 1997, the FASB issued SFAS No. 131, "Disclosure About
              Segments of an Enterprise and Related Information." SFAS No. 131
              establishes standards for the way that public enterprises report
              information about operating segments. It also establishes
              standards for related disclosures about products and services,
              geographic areas and major customers. The Company has determined
              that it does not have any reportable segments.

              In June 1998, the FASB issued SFAS No. 133, "Accounting for
              Derivative Instruments and Hedging Activities." SFAS No. 133
              establishes accounting and reporting standards for derivative
              instruments, including derivative instruments embedded in other
              contracts, and for hedging activities. Subsequently, the FASB
              issued SFAS No. 137 which deferred the effective date of SFAS No.
              133. SFAS No. 137 is effective for all fiscal quarters of fiscal
              years beginning after June 15, 2000. This statement is not
              expected to affect the Company, as the Company does not have any
              derivative instruments or engage in hedging activities.

                          Notes to Financial Statements


         (g)  INCOME TAXES

              Income taxes are accounted for under the asset and liability
              method. Deferred tax assets and liabilities are recognized for the
              future tax consequences attributable to differences between the
              financial statement carrying amounts of existing assets and
              liabilities and their respective tax bases and operating loss and
              tax credit carryforwards. Deferred tax assets and liabilities are
              measured using enacted tax rates expected to apply to taxable
              income in the years in which those temporary differences are
              expected to be recovered or settled. The effect on deferred tax
              assets and liabilities of a change in tax rates is recognized in
              income in the period that includes the enactment date.

        (h)   NET INCOME (LOSS) PER COMMON SHARE

              The net loss per common share is computed by dividing the net
              income (loss) by the weighted average number of shares outstanding
              for each period shown. There are no differences in basic and
              diluted loss per share for the Company related to any of the years
              presented. The net loss per common share for all periods presented
              excludes any common shares issuable upon exercise of outstanding
              stock options or warrants since such inclusion would be
              antidilutive.

2.      INVESTMENT SECURITIES

        In January of 1994, the Company converted its Class B preferred stock of
        MacGregor Sports and Fitness into 133,904 shares of unrestricted common
        stock. This conversion was completed in April of 1994 resulting in the
        Company owning 167,360 unrestricted shares of MacGregor's common stock
        at December 31, 1994. During the fourth quarter of 1995, the Company
        sold 133,904 of the shares in the open market for $208,567. During
        January of 1996, the Company sold an additional 27,500 shares in the
        open market for $89,503 leaving 5,956 shares still owned by the Company.

        MacGregor successfully merged with Technical Publishing Solutions, Inc.
        on July 31, 1996 and the combined entity was renamed IntraNet Solutions.
        IntraNet provides integrated solutions to large corporations for the
        management and distribution of business critical information contained
        in documents using proprietary and standard internet technologies. In
        October 1996, IntraNet declared a 1-for-4 reverse stock split resulting
        in 1,489 shares still owned by the Company at December 31, 1998. During
        1999, the Company sold 1,000 shares on the open market for $22,221,
        leaving 489 shares still owned by the Company.

        At December 31, 1999, the Company's historical cost of the securities
        was $1,301. The fair value at that date was $18,093, resulting in an
        unrealized gain of $16,792. At December 31, 1998, the Company's
        historical cost of the securities was $3,958. The fair value at that
        date was $7,259, resulting in an unrealized gain of $3,301.

                          Notes to Financial Statements


3.      NOTE RECEIVABLE FROM OPTICON MEDICAL INC.

        On November 29, 1999, the Company executed a 8.5% note payable with
        Opticon Medical Inc. On December 9, 1999, the Company entered into an
        Agreement and Plan of Reorganization, providing for the merger of the
        Opticon Medical Inc. into the Company. This transaction closed on
        February 25, 2000 (see Note 6).

4.      INCOME TAXES

        The Company has net operating loss carryforwards of approximately
        $860,000 at December 31, 1999, which can be used to offset future
        taxable income. These net operating loss carryforwards, if not used,
        will expire in the years 2000-2019. The Company had a deferred tax asset
        of $292,000 and $302,000 at December 31, 1999 and 1998, respectively,
        that relates primarily to the aforementioned net operating losses. A
        valuation allowance equal to the full amount of the related deferred tax
        asset has been recorded due to the uncertainty of realization of the
        deferred tax asset.

        Under Sections 382 and 383 of the Internal Revenue Code (IRC) of 1986,
        as amended, the utilization of the net operating loss carryforwards may
        be limited under the change in stock ownership rules.

5.      STOCKHOLDERS' EQUITY

        On July 5, 1988, the Company completed a sale of 300,000 units of its
        $.0001 par value common stock in a public offering. Net proceeds from
        the sale were $700,239 after deducting the Underwriter's commission of
        $90,000 and direct offering costs of $109,761.

        Each unit consisted of one share of the Company's common stock, one
        Class A common stock purchase warrant and one Class B common stock
        purchase warrant. One Class A unit warrant entitles the holder to
        purchase one share of common stock at $4.50 per share. One Class B unit
        warrant entitles the holder to purchase one share of common stock at
        $6.00 per share. The Class A and Class B warrants expired on December
        16, 1995.

                          Notes to Financial Statements


        STOCKHOLDERS' EQUITY (continued)

        In October and November, 1988, Class A warrants to purchase a total of
        18,233 shares of common stock of the Company were exercised at $4.50 per
        share for total proceeds of $81,950, net of costs. In October 1988,
        Class B warrants to purchase 1,000 shares of common stock were exercised
        at $6.00 per share for total proceeds of $6,000. In January 1989, Class
        A warrants to purchase a total of 12,733 shares of common stock of the
        Company were exercised at $4.50 per share for total proceeds of $57,046,
        net of costs.

        During October and November 1999, the Company sold 1,000,000 shares of
        common stock at a price of $0.30. The Company received cash proceeds of
        $166,000, less issuance costs of $1,665, for 553,334 shares. In
        addition, the Company executed a stock subscription agreement for
        $100,000 for 333,333 shares and issued 113,333 shares to the Company's
        Officers/Directors at fair value in settlement of outstanding fees. The
        stock subscription receivable accrues interest at 8.5% per year. This
        receivable was collected in January 2000.

        On February 10, 1997, the Company's shareholders approved a 1-for-100
        reverse split whereby every one hundred shares of the Company's $.0001
        par value common stock were converted to one share of $.0001 par value
        common stock. The shareholders also approved a reduction in the number
        of authorized shares from 950,000,000 to 25,000,000 effective March 3,
        1997. The financial statements herein have been adjusted to reflect the
        1-for-100 reverse stock split back to the date of inception.

        On January 20, 2000, The Company's shareholders approved a 1-for-3
        reverse stock split and authorized 1,000,000 shares of preferred stock
        and an increase in the authorized capital stock to 26,000,000 shares.
        The financial statements herein have been adjusted to reflect the
        1-for-3 reverse stock split back to the date of inception.

(6)     SUBSEQUENT EVENTS AND LIQUIDITY

        On December 9, 1999, the Company entered into an Agreement and Plan of
        Reorganization (the "Merger Agreement") with Opticon Medical Inc., an
        Iowa Corporation. The Merger became effective February 25, 2000.

        At the effective date of the Merger, each outstanding share of Opticon
        common and preferred stock was converted to the right to receive 1.23
        shares of Company common stock, $.0001 par value, so that, in the
        aggregate, the holders of the Opticon's stock would, on the effective
        date, hold 80% of the outstanding common stock of the Company, on a
        fully diluted basis.

        The Merger Agreement provided that the Company assume Opticon's rights
        and obligations under all of Opticon's outstanding options, warrants and
        other purchase rights. As a result, on the effective date, the right of
        any holder of an outstanding option, warrant, or other purchase right,
        was converted into the right to receive the number of shares of Company
        common stock as would have been issued or delivered to the holder if it
        had exercised the warrant or option and received the shares of Opticon
        stock upon such exercise immediately prior to the effectiveness of the
        Merger. At the option of the holder, the Debentures may be converted,
        either in whole or in part, into common shares, at any time, and from
        time to time, at a conversion price per share of common stock equal to
        the lesser of: (a) $4.50 and (b) 65% of the market price of the Company.
        On the third anniversary of the Debentures, the Company shall convert
        all debt outstanding at the conversion price unless such conversion
        would exceed 19.99% of the common stock outstanding on the mandatory
        conversion date, unless the Company's shareholders approve the issuance
        of an amount of the common stock in excess of the 19.99% threshold. In
        the event of no shareholder approval, any amounts in excess of the
        19.99% threshold are to be redeemed in cash.

                          Notes to Financial Statements


        SUBSEQUENT EVENTS AND LIQUIDITY (continued)

        The transaction between Opticon and the Company is a business
        combination between an operating enterprise (Opticon) and a "shell
        company," (the Company) in which the shell company is the issuer of
        securities and the operating enterprise has been determined to be the
        acquiring enterprise for financial reporting purposes. Thus, the
        business combination will be treated for financial reporting purposes as
        an issuance of securities by Opticon.

        Immediately following the merger, the Company entered into Securities
        Purchase Agreements with certain investors whereby the Company agreed to
        sell, and the Investors to purchase $3 million in principal amount of 6%
        convertible debentures and warrants to purchase 300,000 shares of the
        Company's common stock.

        The convertible debt will be recorded at the amount of gross proceeds
        less the fair value of the warrants. The calculated conversion price at
        February 25, 2000, the first available conversion date, was $2.93 per
        share. In accordance with the FASB's Emerging Issues Task Force Issue
        98-5, the difference between this conversion price and the market price
        of $4.50 per share will be reflected as additional interest expense in
        the merged company's statement of operations for the quarter ended March
        31, 2000.

        On March 22, 2000, the convertible debentures were exchanged for 3,000
        shares of Series A 6% Preferred Stock. The Preferred Stock has
        conversion terms identical to the Convertible Debentures. In addition,
        the Preferred Stockholders will be entitled to 6% dividends payable
        quarterly in cash or common stock.

        The Company has suffered recurring losses from operations. The merged
        company intends to use the proceeds from the convertible debentures, as
        well as proceeds from potential future debt or equity financing, to more
        fully establish its infrastructure and continue Opticon's research and
        development activities. There can be no assurance that the Company will
        be able to raise sufficient capital to fully establish its
        infrastructure and continue to execute its business plans. These
        circumstances raise substantial doubt about the Company's ability to
        continue as a going concern. The financial statements do not include any
        adjustments that might result from the outcome of this uncertainty.

                          INDEPENDENT AUDITORS' REPORT



     The Board of Directors and Stockholders
     Opticon Medical Inc.

     We have audited the accompanying balance sheet of Opticon Medical Inc. (a
     development stage enterprise) as of December 31, 1999, and the related
     statements of operations, stockholders' equity (deficit), and cash flows
     for year ended December 31, 1999 and for the period from July 28, 1994
     (inception) to December 31, 1999. 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 audit. The
     cumulative statements of operations, stockholders' equity (deficit), and
     cash flows for the period July 28, 1994 (inception) to December 31, 1999
     include amounts for the period from July 28, 1994 (inception) to December
     31, 1998 and year ended December 31, 1998, which were audited by other
     auditors whose report has been furnished to us, and our opinion, insofar as
     it relates to the amounts included for the period July 28, 1994 through
     December 31, 1998 is based solely on the report of the other auditors.

     We conducted our audit 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 audit
     provides a reasonable basis for our opinion.

     In our opinion, based on our audit and the report of the other auditors,
     the financial statements referred to above present fairly, in all material
     respects, the financial position of Opticon Medical Inc. (a development
     stage enterprise) as of December 31, 1999, and the results of its
     operations and its cash flows for each of the year ended December 31, 1999
     and for the period July 28, 1994 (inception) to December 31, 1999, in
     conformity with generally accepted accounting principles.

     The accompanying financial statements have been prepared assuming that the
     Company will continue as a going concern. As discussed in Note 8 to the
     financial statements, the Company has suffered recurring losses from
     operations and has a net capital deficiency that raise substantial doubt
     about its ability to continue as a going concern. The financial statements
     do not include any adjustments that might result from this uncertainty.

                              OPTICON MEDICAL INC.
                        (a development stage enterprise)

                        Notes to the Financial Statements

1.      NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

        (a)   NATURE OF BUSINESS

              Opticon Medical Inc. (the Company) was incorporated in Iowa on
              July 28, 1994 and is currently headquartered in Dublin, Ohio. The
              Company was formed to design, develop and market innovative,
              cost-effective disposable devices to manage and control the
              symptoms of urinary incontinence in adults. The Company plans to
              market its product in the United States and other world markets
              using multiple distribution channels.

              The accompanying financial statements have been prepared on the
              basis that the Company will continue as a going concern, which
              contemplates the realization of assets and satisfaction of
              liabilities in the normal course of business. The Company has
              incurred operating losses in each period since inception. There is
              no assurance that the Company will be profitable in the future.

        (b)   CASH AND CASH EQUIVALENTS

              Cash equivalents consist of overnight repurchase agreements with
              an initial term of less than three months. For purposes of the
              statement of cash flows, the Company considers all highly liquid
              debt instruments with original maturities of three months or less
              to be cash equivalents.

        (c)   PROPERTY AND EQUIPMENT

              Property and equipment are recorded at cost. Property and
              equipment under capital leases are stated at the present value of
              the minimum lease payments.

              Depreciation on property and equipment is calculated using
              accelerated methods (primarily double declining balance) over the
              estimated useful lives of the assets ranging from three to seven
              years. Property and equipment held under capital leases and
              leasehold improvements are amortized straight line over the
              shorter of the lease term or estimated useful life of the asset
              and is included in depreciation. Maintenance, repairs and minor
              renewals are expensed when incurred.

        (d)   RESEARCH AND DEVELOPMENT COSTS

              Research and development costs are charged to expense when
              incurred.

        (e)   INTANGIBLES

              The Company's founder paid certain patent and intellectual
              property costs prior to incorporating the Company. The founder
              contributed this property in exchange for common stock valued at
              $219,350. These amounts were capitalized and are being amortized
              using the straight-line method over 17 years. Intellectual
              property consists of designs, concepts and inventions related to
              the Company's urinary product development.

                        Notes to the Financial Statements


        (f)   USE OF ESTIMATES

              The preparation of financial statements in conformity with
              generally accepted accounting principles requires management to
              make estimates and assumptions that affect the reported amounts of
              assets and liabilities and disclosure of contingent assets and
              liabilities at the date of financial statements and the reported
              amounts of revenues and expenses during the reporting period.
              Actual results could differ from those estimates.

        (g)   FINANCIAL INSTRUMENTS

              At December 31, 1999 and 1998, the financial statement carrying
              amounts of cash and cash equivalents, current assets, current
              liabilities and current notes payable approximated the fair value
              of these instruments because of the short-term maturity of these
              instruments.

        (h)   RECENT PRONOUNCEMENTS

              In June 1998, the FASB issued SFAS No. 133, "Accounting for
              Derivative Instruments and Hedging Activities." SFAS No. 133
              establishes accounting and reporting standards for derivative
              instruments, including derivative instruments embedded in other
              contracts, and for hedging activities. Subsequently, the FASB
              issued SFAS No. 137 which deferred the effective date of SFAS No.
              133. SFAS No. 137 is effective for all fiscal quarters of fiscal
              years beginning after June 15, 2000. This statement is not
              expected to affect the Company, as the Company does not have any
              derivative instruments or engage in hedging activities.

        (i)   INCOME TAXES

              Income taxes are accounted for under the asset and liability
              method. Deferred tax assets and liabilities are recognized for the
              future tax consequences attributable to differences between the
              financial statement carrying amounts of existing assets and
              liabilities and their respective tax bases and operating loss and
              tax credit carryforwards. Deferred tax assets and liabilities are
              measured using enacted tax rates expected to apply to taxable
              income in the years in which those temporary differences are
              expected to be recovered or settled. The effect on deferred tax
              assets and liabilities of a change in tax rates is recognized in
              income in the period that includes the enactment date.

        (j)   IMPAIRMENT OF LONG-LIVED ASSETS AND LONG-LIVED ASSETS TO BE
              DISPOSED OF

              Long-lived assets and certain identifiable intangibles are
              reviewed for impairment whenever events or changes in
              circumstances indicate that the carrying amount of an asset may
              not be recoverable. Recoverability of assets to be held and used
              is measured by a comparison of the carrying amount of an asset to
              future net undiscounted cash flows expected to be generated by the
              asset. If such assets are considered to be impaired, the
              impairment to be recognized is measured by the amount by which the
              carrying amount of the assets exceeds the fair value of the
              assets. Assets to be disposed of are reported at the lower of the
              carrying amount or fair value less cost to sell.

        (k)   ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES

              The Company applies the intrinsic value-based method of accounting
              prescribed by Accounting Principles Board ("APB") Opinion No. 25,
              "Accounting for Stock Issued to Employees," and related
              interpretations, in accounting for its fixed plan stock options.
              As such, compensation expense would be recorded on the date of
              grant only if the current market price of the underlying stock
              exceeded the exercise price. SFAS No. 123, "Accounting for
              Stock-Based Compensation," established accounting and disclosure
              requirements using a fair value-based method of accounting for
              stock-based employee compensation plans. As allowed by SFAS No.
              123, the Company has elected to continue to apply the intrinsic
              value-based method of accounting described above, and has adopted
              the disclosure requirements of SFAS No. 123.

5.      INCOME TAXES

        The Company has net operating loss carryforwards of approximately $4.1
        million at December 31, 1999, which can be used to offset future taxable
        income. These net operating loss carryforwards, if not used, will expire
        in the years 2009-2019. The Company had a deferred tax asset of
        $1,504,000 and $1,050,000 at December 31, 1999 and 1998, respectively,
        that relates primarily to the aforementioned net operating losses. A
        valuation allowance equal to the full amount of the related deferred tax
        asset has been recorded due to the uncertainty of realization of the
        deferred tax asset.

        Under Sections 382 and 383 of the Internal Revenue Code (IRC) of 1986,
        as amended, the utilization of the net operating loss carryforwards may
        be limited under the change in stock ownership rules.

6.      STOCKHOLDERS' EQUITY

        PRIVATE PLACEMENTS OF COMMON STOCK AND WARRANTS - During 1995 and 1996,
        the Company sold 499,995 shares of its common stock in a private
        placement for $1.00 per share and received net proceeds of $499,995. A
        second private placement of common stock was completed in 1996 for
        300,000 shares of common stock for $1.00 per share and resulted in net
        proceeds of $300,000. In connection with the second private placement,
        the Company issued warrants to purchase 300,000 shares of common stock
        at $1.00. The warrants are exercisable for 10 years.

        CONVERSION OF DEBT - During 1994, the Company entered into a venture
        agreement with Iowa Seed Capital Corporation. The venture agreement
        provided for a convertible loan of $115,000 and required the Company to
        pay a percentage of revenues in lieu of interest as defined in the
        agreement. The loan was converted into 150,000 shares of common stock in
        November 1997.

        During January 1998, the Company approved the issuance of Series 1998
        Convertible Debentures (the Debentures) of up to $750,000. The
        Debentures accrued interest at 10%, and were secured by substantially
        all of the assets of the Company. During 1998, the Company issued
        Debentures in the amount of $525,000 and issued detachable warrants to
        purchase an aggregate of 378,512 shares of common stock at an exercise
        price of $1.50 exercisable for ten years. The proceeds from the issuance
        of the Debentures and warrants were allocated between the Debentures and
        warrants based on the relative fair value of the two securities at the
        time of issuance. The resulting original issuance discount of $71,500
        was amortized as interest expenses during the year ended December 31,
        1998. The principal and accrued interest on the Debentures were
        converted into 378,512 shares of the Company's Series B convertible
        preferred stock in December 1998 at a conversion price of $1.50 per
        share.

        During August 1998, a stockholder of the Company advanced the Company
        $300,000 pursuant to a convertible promissory note. The convertible
        promissory note accrued interest at 6%. The principal and four months'
        accrued interest on the loan were converted into 204,266 shares of the
        Company's Series B preferred stock in December 1998 at a conversion
        price of $1.50 per share. Concurrent with the issuance of the
        convertible promissory note, the Company also issued a ten year warrant
        to purchase 30,000 shares of common stock of the Company to the
        stockholder at an exercise price of $1.50 per share. The proceeds from
        the issuance of the convertible promissory note and warrants were
        allocated between the convertible promissory note and warrants based on
        the relative fair value of the two securities at the time of issuance.
        The resulting original issuance discount of $7,000 was amortized as
        interest expense during the year ended December 31, 1998.

        STOCKHOLDERS' EQUITY (continued)

        PRIVATE PLACEMENT OF SERIES A CONVERTIBLE PREFERRED STOCK - During 1996
        and 1997, the Company sold 1,062,633 shares of Series A convertible
        preferred stock (Series A preferred stock) in a private offering for
        $1.50 per share and received net proceeds of $1,541,581. Dividends are
        payable on the Series A preferred stock only if declared by the Board of
        Directors. No dividends have been declared to date. The Series A
        preferred stockholders are entitled to a liquidation preference of $1.50
        per share. Series A preferred shares are eligible to vote on stockholder
        matters on an "as if converted" basis with holders of the Company's
        common stock. The Series A preferred stock is convertible at the option
        of the holder into common stock at any time on a share-for-share basis.
        The Series A preferred stock will be automatically converted into common
        stock upon the occurrence of a significant initial public offering.

        SERIES B CONVERTIBLE PREFERRED STOCK - During 1998, the Company
        converted debt and accrued interest of $874,167 into 582,778 shares of
        Series B convertible preferred stock (Series B preferred stock).
        Dividends are payable on the Series B preferred stock only if declared
        by the Board of Directors. No dividends have been declared to date. The
        Series B preferred stockholders are entitled to a liquidation preference
        of $1.50 per share. Series B preferred shares are eligible to vote on
        stockholder matters on an "as if converted" basis with holders of the
        Company's common stock. The Series B preferred stock is convertible at
        the option of the holder into common stock at any time on a
        share-for-share basis. The Series B preferred stock will be
        automatically converted into common stock upon the occurrence of a
        significant initial public offering.

        In February, May and June 1999, the Company sold 350,000 shares of its
        Series B convertible preferred stock in a private placement for $1.50
        per share, and received gross proceeds of $525,000. Concurrent with the
        issuance of the Series B preferred shares, the Company also issued five
        year warrants to purchase 60,000 shares of common stock of the Company
        at an exercise price of $2.00 per share.

        STOCK OPTION PLANS - The Company adopted an Incentive Stock Option Plan,
        pursuant to which options to acquire an aggregate of 1,000,000 shares of
        the Company's common stock may be granted at fair market value as
        determined by the Board of Directors. In general, the options granted
        vest as determined by the Board of Directors ranging from immediately to
        four years, and expire five or ten years from the date of the grant. In
        addition, the Company adopted a Director Stock Option Plan, pursuant to
        which options to acquire an aggregate of 1,000,000 shares of the
        Company's common stock may be granted at fair market value as determined
        by the Board of Directors. In general, the options granted vest as

        The Company applies APB Opinion 25 "Accounting for Stock Issued to
        Employees" and related Interpretations in accounting for its stock
        options. According, no compensation cost has been recognized for its

        In determining the compensation cost of the options granted, as
        specified by Statement 123, the fair value of each option grant has been
        estimated on the date of grant using the following assumptions:

               Risk free interest rate                          5.5%
               Expected life of options granted            5-10 years

7.      RELATED PARTIES

        EMPLOYMENT AGREEMENTS -The Company has employment agreements with two of
        its officers. In February 1998, the agreements were amended whereby the
        officers elected to defer a portion of their annual compensation. The
        deferred amount accrues interest at 10% and is convertible into
        approximately 36,000 shares of Series B preferred stock at $1.50 per
        share as defined in the amended agreements. At December 31, 1999, the
        Company had accrued deferred compensation totaling $164,000. The Company
        had also accrued $20,700 at December 31, 1999 in interest under these
        agreements, which is included in accrued interest due to related
        parties. Subsequent to year-end, the Company settled all of these
        obligations in cash, with the exception of $22,000, which was used to
        exercise outstanding stock options.

        CONSULTING AGREEMENTS - On November 1, 1997, the Company entered into a
        consulting agreement with a director, stockholder and the original
        founder of the Company. The agreement is for a four-year period and
        requires annual consulting fees of $110,000 for the first two years and
        $75,000 for the last two years of the agreement. The agreement includes
        a two-year non-compete provision. In addition, the Company also has a
        consulting agreement with a consulting company affiliated with a member
        of the Company's Board of Directors. The Company incurred costs of
        $45,150 in 1999 and $60,000 in 1998 under this agreement. Amounts due
        under both agreements are included in accrued liability due to related
        parties for consulting services in the accompanying balance sheets.

                        Notes to the Financial Statements


 8.     SUBSEQUENT EVENTS AND LIQUIDITY

        On December 9, 1999, the Company entered into an Agreement and Plan or
        Reorganization (the "Merger Agreement") with Immune Response, Inc
        (Immune), a Colorado Corporation. The Company's shareholders approved
        and adopted the merger agreement on January 28, 2000. The Merger became
        effective February 25, 2000.

        At the effective date of the Merger, each outstanding share of common
        stock, Series A preferred stock, and Series B preferred stock was
        converted to the right to receive 1.23 shares of common stock, $.0001
        par value, of Immune, so that, in the aggregate, the holders of the
        Company's stock would, on the effective date, hold 80% of the
        outstanding common stock of Immune, on a fully diluted basis.

        The Merger Agreement provided that Immune assume the Company's rights
        and obligations under all of the Company's outstanding options, warrants
        and other purchase rights. As a result, on the effective date, the right
        of any holder of an outstanding option, warrant, or other purchase
        right, was converted into the right to receive the number of shares of
        Immune common stock as would have been issued or delivered to the holder
        if it had exercised the warrant or option and received the shares of
        Company stock upon such exercise immediately prior to the effectiveness
        of the Merger.

        The transaction between Immune and the Company is a business combination
        between an operating enterprise (the Company) and a "shell company,"
        (Immune) in which the shell company is the issuer of securities and the
        operating enterprise has been determined to be the acquiring enterprise
        for financial reporting purposes. Thus, the business combination will be
        treated for financial reporting purposes as an issuance of securities by
        the Company.

        Immediately following the merger, Immune entered into Securities
        Purchase Agreements with certain investors whereby Immune agreed to
        sell, and the Investors to purchase $3 million in principal amount of 6%
        convertible debentures and warrants to purchase 300,000 shares of
        Immune's common stock at a price of $6.60 per share. At the option of
        the holder, the Debentures may be converted, either in whole or in part,
        into common shares, at any time, and from time to time, at a conversion
        price per share of common stock equal to the lesser of: (a) $4.50 and
        (b) 65% of the market price of Immune Response, Inc. On the third
        anniversary of the Debentures, Immune shall convert all debt outstanding
        at the conversion price unless such conversion would exceed 19.99% of
        the common stock outstanding on the mandatory conversion date, unless
        Immune's shareholders approve the issuance of an amount of the common
        stock in excess of the 19.99% threshold. In the event of no shareholder
        approval, any amounts in excess of 19.99% are to be redeemed for cash.

        The convertible debt will be recorded at the amount of gross proceeds
        less the fair value of the warrants. The calculated conversion price at
        February 25, 2000, the first available conversion date, was $2.93 per
        share. In accordance with the FASB's Emerging Issues Task Force Issue
        98-5, the difference between this conversion price and the market price
        of $4.50 per share will be reflected as additional interest expense in
        the merged company's statement of operations for the quarter ended March
        31, 2000.

                        Notes to the Financial Statements


        SUBSEQUENT EVENTS AND LIQUIDITY (continued)

        On March 22, 2000, the convertible debentures were exchanged for 3,000
        shares of Series A 6% Preferred Stock. The Preferred Stock has
        conversion terms identical to the Convertible Debentures. In addition,
        the Preferred Stockholders will be entitled to 6% dividends payable
        quarterly in cash or common stock.

        The Company has suffered recurring losses from operations and has a net
        capital deficiency as of December 31, 1999. The merged company intends
        to use the proceeds from the convertible debentures, as well as proceeds
        from potential future debt or equity financing, to more fully establish
        its infrastructure and continue its research and development activities.
        There can be no assurance that the Company will be able to raise
        sufficient funds to fully establish its infrastructure and continue its
        research and development activities and continue to execute its business
        plans. These circumstances raise substantial doubt about the Company's
        ability to continue as a going concern. The financial statements do not
        include any adjustments that might result from the outcome of this
        uncertainty.

              Pro Forma Condensed Consolidated Financial Statements
                                   (unaudited)

On December 9, 1999, the Company, Opticon Acquisition Corporation, a Delaware
corporation and wholly-owned subsidiary of the Company ("Sub"), and Opticon
Medical, Inc. (Opticon), an Iowa corporation entered into an Agreement and Plan
of Reorganization (the "Merger Agreement"), providing for the merger of Opticon
with and into Sub (the "Merger").

The Merger Agreement was approved by the Company, acting as sole shareholder of
Sub. The shareholders of Opticon approved and adopted the Merger Agreement at a
special meeting held on January 28, 2000. The Merger became effective February
25, 2000. Through the Certificate of Merger, Sub changed its name to Opticon
Medical, Inc.

At the Effective Date of the Merger, each outstanding share of Common Stock, no
par value, Series A Preferred Stock, no par value, and Series B Preferred Stock,
no par value, of Opticon, totaling 4,482,906 shares (the "Opticon Stock") and
held by approximately 88 shareholders, was converted into the right to receive
1.23 shares of common stock, $.0001 par value, of the Company (the "Company
Common Stock"), so that, in the aggregate, the holders of Opticon Stock would,
on the Effective Date, hold 80% of the outstanding Company Common Stock, on a
fully diluted basis, and the then current shareholders of the Company would
hold, in the aggregate, 20% of the outstanding Company Common Stock on a fully
diluted basis. No fractional shares were issued. All fractional shares of
Company Common Stock to which a holder of Opticon Stock would otherwise be
entitled at the Effective Date were aggregated, and any fractional share
resulting from such aggregation was rounded to the nearest whole. All shares
issued pursuant to the Merger Agreement were issued pursuant to exemptions from
registration under the Securities Act of 1933, as amended (the "Act").

No other consideration was provided in connection with the Merger. The merger
consideration was determined based upon arms-length negotiations between the
Company and Opticon.

The Merger Agreement provided that the Company assume Opticon's rights and
obligations under all of Opticon's outstanding options and warrants and other
purchase rights. As a result, on the Effective Date, the right of any holder of
an outstanding option, warrant, or other purchase right, was converted into the
right to receive the number of shares of Company Common Stock as would have been
issued or delivered to the holder if it had exercised the warrant or option and
received the shares of Opticon Stock upon such exercise immediately prior to the
effectiveness of the Merger. At the Effective Date, there were outstanding an
aggregate of 1,968,517 Opticon options and warrants.

In connection with the Merger, on January 20, 2000, the Company's shareholders
approved a one-for-three reverse stock split and authorized 1,000,000 shares of
preferred stock and an increase in the authorized capital stock to 26,000,000
shares. As a result, prior to the Effective Date, the Company had a total of
1,983,526 shares of Company Common Stock issued and outstanding. In the Merger,
5,513,974 shares of Company Common Stock were issued in exchange for the
outstanding shares of Opticon Stock, causing the Company to have a total of
7,497,500 shares of Company Common Stock issued and outstanding. If all of the
Opticon options and warrants were to be exercised, approximately another
2,421,276 shares of Company Common Stock would be issued.

Immediately following the Merger, the Company entered into Securities Purchase
Agreements with certain investors (the "Investors") whereby the Company agreed
to sell, and the Investors to purchase $3,000,000 in principal amount of 6%
Redeemable Convertible Debentures ("Debentures"), and warrants to purchase
300,000 shares of Company Common Stock ("Warrants"), for an aggregate purchase
price of $3,000,000.

The transaction between the Company and Opticon is a business combination
between an operating enterprise (Opticon) and a "shell company," (the Company)
in which the shell company is the issuer of securities and the operating
enterprise has been determined to be the acquiring enterprise for financial
reporting purposes. In this case, the business combination is being treated for
financial reporting purposes as an issuance of securities by Opticon. Opticon
will credit equity for the fair value of the tangible net assets of the Company
(i.e., no goodwill or intangible assets will be recognized in this transaction).
Costs related to this transaction will be charged directly to equity.

In future filings, the historical financial statements of Opticon (accounting
acquirer) will be presented as the


                                      F-34
<PAGE>   70

historical financial statements of the combined enterprise and the assets and
liabilities of the Company (legal acquirer) will be accounted for as required by
the purchase method of accounting without regard to which enterprise is the
surviving enterprise. The results of operations of the Company (legal acquirer)
will be included in the financial statements of the combined enterprise only
from the date of acquisition. The equity of Opticon will be presented as the
equity of the combined enterprise; however, the capital stock account of Opticon
will be adjusted to reflect the par value of the outstanding stock of the
Company after giving effect to the number of shares issued in the business
combination. The difference between the capital stock account of Opticon and the
capital stock account of the Company will be recorded as an adjustment to
additional paid-in capital of the combined enterprise. For periods prior to the
business combination, the equity of the combined enterprise will be the
historical equity of Opticon prior to the merger retroactively restated to
reflect the number of shares received in the business combination. The
accumulated deficit of Opticon will be carried forward after the acquisition.
Earnings (loss) per share for periods prior to the business combination will be
restated to reflect the number of equivalent shares received by Opticon.

The unaudited Pro Forma Condensed Consolidated Statement of Operations for the
year ended December 31, 1999 gives affect to the acquisition of Opticon as if it
had occurred on January 1, 1999. The Pro Forma Statement of Operations is based
on historical results of operations of the Company and Opticon for the year
ended December 31, 1999. The unaudited Pro Forma Condensed Balance Sheet as of
December 31, 1999 gives effect to the acquisition of Opticon as if the
acquisition has occurred on that date. The Pro Forma Statement of Operations and
the Pro Forma Balance Sheet and accompanying notes (the "Pro Forma financial
information") should be read in conjunction with and are qualified by the
historical financial statements of the Company and Opticon and notes thereto.

The Pro Forma Financial Information is intended for informational purposes only
and is not necessarily indicative of the future financial position or future
results of operations of the consolidated Company after the acquisition of
Opticon, or of the financial position or results of operations of the
consolidated Company that would have actually occurred has the acquisition of
Opticon been effected on January 1, 1999.

         Notes to Pro Forma Condensed Consolidated Financial Statements
                                   (unaudited)

1.       PRO FORMA ADJUSTMENTS AND ASSUMPTIONS

(a)      On December 9, 1999, the Company, Opticon Acquisition Corporation, a
         Delaware corporation and wholly-owned subsidiary of the Company
         ("Sub"), and Opticon Medical, Inc. (Opticon), an Iowa corporation
         entered into an Agreement and Plan of Reorganization (the "Merger
         Agreement"), providing for the merger of Opticon with and into Sub (the
         "Merger").

         The Merger Agreement was approved by the Company, acting as sole
         shareholder of Sub. The shareholders of Opticon approved and adopted
         the Merger Agreement at a special meeting held on January 28, 2000. The
         Merger became effective February 25, 2000.

         At the Effective Date of the Merger, each outstanding share of Common
         Stock, no par value, Series A Preferred Stock, no par value, and Series
         B Preferred Stock, no par value, of Opticon, totaling 4,482,906 shares
         (the "Opticon Stock") and held by approximately 88 shareholders, was
         converted into the right to receive 1.23 shares of common stock, $.0001
         par value, of the Company (the "Company Common Stock"), so that, in the
         aggregate, the holders of Opticon Stock would, on the Effective Date,
         hold 80% of the outstanding Company Common Stock, on a fully diluted
         basis, and the then current shareholders of the Company would hold, in
         the aggregate, 20% of the outstanding Company Common Stock on a fully
         diluted basis. No fractional shares were issued. All fractional shares
         of Company Common Stock to which a holder of Opticon Stock would
         otherwise be entitled at the Effective Date were aggregated, and any
         fractional share resulting from such aggregation was rounded to the
         nearest whole. All shares issued pursuant to the Merger Agreement were
         issued pursuant to exemptions from registration under the Securities
         Act of 1933, as amended (the "Act").

         No other consideration was provided in connection with the Merger. The
         merger consideration was determined based upon arms-length negotiations
         between the Company and Opticon.

         In the Merger, 5,513,974 shares of Company Common Stock were issued in
         exchange for the outstanding shares of Opticon Stock, causing the
         Company to have a total of 7,497,500 shares of Company Common Stock
         issued and outstanding.

         The transaction between the Company and Opticon is a business
         combination between an operating enterprise (Opticon) and a "shell
         company," (the Company) in which the shell company is the issuer of
         securities and the operating enterprise has been determined to be the
         acquiring enterprise for financial reporting purposes. Thus, the
         business combination is being treated for financial reporting purposes
         as an issuance of securities by Opticon. Opticon credited equity for
         the fair value of the tangible net assets of the Company (i.e., no
         goodwill or intangible assets were recognized in this transaction).
         Costs related to this transaction, totaling $90,570, have been charged
         directly to equity.

         In addition, the intercompany notes, totaling $100,000, and the related
         accrued interest totaling $745 were canceled in the Merger.


(b)      In connection with the Merger, the Company entered into Securities
         Purchase Agreements with certain investors (the "Investors") whereby
         the Company agreed to sell, and the Investors to purchase $3,000,000 in
         principal amount of 6% Redeemable Convertible Debentures
         ("Debentures"), and warrants to purchase 300,000 shares of Company
         Common Stock ("Warrants"), for an aggregate purchase price of
         $3,000,000.

         The Company received gross proceeds from the Debenture issuance of
         $3,000,000, less issuance costs of $452,735, resulting in net proceeds
         of $2,547,265. The issuance costs, which have been recorded as an
         asset, will be amortized as interest expense over the 3 year life of
         the Debentures. Total amortization in 1999 if the Debentures had been
         outstanding for the entire period would have been $150,912.

         Notes to Pro Forma Condensed Consolidated Financial Statements
                                   (unaudited)

         The Company also recorded the warrants at their fair value ($775,000
         calculated using a Black Sholes valuation model) as a discount on the
         face amount of the Debentures with a corresponding credit to additional
         paid-in capital. This discount will also be amortized as interest
         expense over the 3 year life of the Debentures. Total amortization in
         1999 if the Debentures had been outstanding for the entire period would
         have been $258,333.

         The calculated conversion price of the Debentures at February 25, 2000,
         the first available conversion date, was $2.93 per share. In accordance
         with the FASB's Emerging Issues Tax Force Issue 98-5, the difference
         between this conversion price and the market price of $4.50 per share
         were reflected as additional interest expense in the Company's Pro
         Forma Condensed Statement of Operations and a credit to additional
         paid-in capital in the Pro Forma Condensed Balance Sheet.

(c)      In the Merger, 5,513,974 shares of Company Common Stock were issued in
         exchange for the outstanding shares of Opticon Stock, causing the
         Company to have a total of 7,497,500 shares of Company Common Stock
         issued and outstanding. The pro forma based and diluted net loss per
         share is computed by dividing the net loss attributable to common
         shareholders by the weighted average number of common shares
         outstanding. The calculation of the weighted average number of shares
         outstanding assumes that shares issued in connection with the Merger
         were outstanding for the entire period. Diluted net loss per share
         equals basic net loss per share, as common stock equivalents are
         anti-dilutive for all pro forma periods presented.

The Board of Directors
Opticon Medical, Inc. (f/k/a Immune Response, Inc.):

We consent to the use of our report included herein and to the reference to our
firm under the heading "Experts" in the prospectus.

Our report dated March 25, 2000, states that we have audited the balance sheet
of Immune Response, Inc. (a development stage enterprise) as of December 31,
1999, and the related statements of operations, stockholders' equity and
comprehensive income, and cash flows for year ended December 31, 1999 and for
the period from May 14, 1984 (inception) to December 31, 1999. The statements of
operations, stockholders' equity, and cash flows for the period May 14, 1984
(inception) to December 31, 1999 include amounts for the period from May 14,
1984 (inception) to December 31, 1998 and for the year ended December 31, 1998,
which were audited by other auditors whose report has been furnished to us, and
our opinion, insofar as it relates to the amounts included for the period May
14, 1984 through December 31, 1998 is based solely on the report of the other
auditors.

Our report dated March 25, 2000, contains an explanatory paragraph that states
that the Company has suffered recurring losses from operations, which raises
substantial doubt about its ability to continue as a going concern. The
financial statements do not include any adjustments that might result from the
outcome of that uncertainty.

NOTE 1 - BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements of Opticon Medical,
Inc. (formerly Immune Response, Inc. - see Note 4) (the "Company") have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-QSB and Item 10(a) of
Regulation S-B. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation have
been included. Operating results for the three and six month periods ended June
30, 2000 are not necessarily indicative of the results that may be expected for
the year ended December 31, 2000. For further information, refer to the
financial statements and footnotes thereto included in the Company's Form 10-KSB
for the year ended December 31, 1999 as filed with the Securities and Exchange
Commission.



NOTE 2 - MERGER OF IMMUNE RESPONSE, INC. AND OPTICON MEDICAL, INC. (AN IOWA
CORPORATION)

On December 9, 1999, Immune Response, Inc., a Colorado corporation ("Immune"),
Opticon Acquisition Corporation, a Delaware corporation and wholly-owned
subsidiary of Immune ("Sub"), and Opticon Medical, Inc., an Iowa corporation
("Opticon Iowa"), entered into an Agreement and Plan of Reorganization (the
"Merger Agreement"), providing for the merger of Opticon Iowa with and into Sub
(the "Merger").

The Merger Agreement was approved by Immune, acting as sole shareholder of Sub.
The shareholders of Opticon Iowa approved and adopted the Merger Agreement at a
special meeting held on January 28, 2000. The Merger became effective February
25, 2000. Through the Certificate of Merger, Sub changed its name to Opticon
Medical, Inc.

At the Effective Date of the Merger, each outstanding share of Common Stock, no
par value, Series A Preferred Stock, no par value, and Series B Preferred Stock,
no par value, of Opticon Iowa, totaling 4,482,906 shares (the "Opticon Iowa
Stock") and held by approximately 88 shareholders, was converted into the right
to receive 1.23 shares of common stock, $.0001 par value, of Immune (the "Immune
Common Stock"), so that, in the aggregate, the holders of Opticon Iowa Stock
would, on the Effective Date, hold 80% of the outstanding Immune Common Stock,
on a fully diluted basis, and the then current shareholders of Immune would
hold, in the aggregate, 20% of the outstanding Immune Common Stock on a fully
diluted basis. No fractional shares were issued. All fractional shares of Immune
Common Stock to which a holder of Opticon Iowa Stock would otherwise be entitled
at the Effective Date were aggregated, and any fractional share resulting from
such aggregation was rounded to the nearest whole. All shares issued pursuant to
the Merger Agreement were issued pursuant to exemptions from registration under
the Securities Act of 1933, as amended (the "Act"). In addition, notes
outstanding between the two companies, totaling $100,000 were cancelled in
connection with the merger. The merger consideration was determined based upon
arms-length negotiations between Immune and Opticon Iowa.

                                      F-44
<PAGE>   80

The Merger Agreement provided that Immune assume Opticon Iowa's rights and
obligations under all of Opticon Iowa's outstanding options and warrants and
other purchase rights. As a result, on the Effective Date, the right of any
holder of an outstanding option, warrant, or other purchase right, was converted
into the right to receive the number of shares of Immune Common Stock as would
have been issued or delivered to the holder if it had exercised the warrant or
option and received the shares of Opticon Iowa Stock upon such exercise
immediately prior to the effectiveness of the Merger. At the Effective Date,
there were outstanding an aggregate of 1,968,517 Opticon Iowa options and
warrants.



In connection with the Merger, on January 20, 2000, Immune's shareholders
approved a one-for-three reverse stock split and authorized 1,000,000 shares of
preferred stock and an increase in the authorized capital stock to 26,000,000
shares. As a result, prior to the Effective Date, Immune had a total of
1,983,526 shares of Immune Common Stock issued and outstanding. In the Merger,
5,513,974 shares of Immune Common Stock were issued in exchange for the
outstanding shares of Opticon Iowa Stock, causing Immune to have a total of
7,497,500 shares of Immune Common Stock issued and outstanding. If all of the
Opticon Iowa options and warrants had been exercised, approximately another
2,421,276 shares of Immune Common Stock would have been issued.



The transaction between Immune and Opticon Iowa was a business combination
between an operating enterprise (Opticon Iowa) and a "shell company" (Immune),
in which the shell company was the issuer of securities and the operating
enterprise was determined to be the acquiring enterprise for financial reporting
purposes. In this case, the business combination is being treated for financial
reporting purposes as an issuance of securities by Opticon Iowa. Opticon Iowa
has credited equity for the fair value of the tangible net assets of Immune
(i.e., no goodwill or intangible assets were recognized in this transaction).
Costs related to this transaction were charged directly to equity.



In this filing and in future filings, the historical financial statements of
Opticon Iowa (accounting acquirer) has and will be presented as the historical
financial statements of the combined enterprise and the assets and liabilities
of the Immune (legal acquirer) has and will be accounted for as required by the
purchase method of accounting without regard to which enterprise is the
surviving enterprise. The results of operations of Immune (legal acquirer) are
included in the financial statements of the combined enterprise only from the
date of acquisition. The equity of Opticon Iowa is presented as the equity of
the combined enterprise; however, the capital stock account of Opticon Iowa has
been adjusted to reflect the par value of the outstanding stock of Immune after
giving effect to the number of shares issued in the business combination. The
difference between the capital stock account of Opticon Iowa and the capital
stock account of Immune has been recorded as an adjustment to additional paid-in
capital of the combined enterprise. For periods prior to the business
combination, the equity of the combined enterprise is the historical equity of
Opticon Iowa prior to the merger retroactively restated to reflect the number of
shares received in the business combination. The accumulated deficit of Opticon
Iowa will be carried forward after the acquisition. Earnings (loss) per share
for periods prior to the business combination have been restated to reflect the
number of equivalent shares received by Opticon Iowa shareholders in the Merger.



NOTE 3 - CONVERTIBLE PREFERRED STOCK SERIES A



Immediately following the Merger, Immune entered into Securities Purchase
Agreements with certain investors (the Investors") whereby Immune agreed to
sell, and the Investors to purchase $3 million in principal amount of 6%
convertible debentures (the "Debentures") and warrants to purchase 300,000
shares of Immune's common stock (the Warrants") at a price of $6.60 per share.
At the option of the holder, the Debentures were convertible, either in whole or
in part, into common shares, at any time, and from time to time, at a conversion
price per share of common stock equal to the lesser of: (a) $4.50 or (b) 65% of
the market price of Immune Common Stock. Any principal amount of Debentures
outstanding on the third anniversary of the issuance were automatically
convertible into common stock at the conversion price unless the common stock
issuable on such conversion would exceed 19.99% of the common stock outstanding
on the mandatory conversion date, in which case Immune's shareholders would have
to approve the issuance of the common stock in excess of the 19.99% threshold.
In the event of no shareholder approval, any unconverted portion of the
Debentures were required to be redeemed for cash.


                                      F-45
<PAGE>   81


The Debentures were recorded at the amount of gross proceeds of $3 million, less
the fair value of the Warrants, which were valued at $775,000. The calculated
conversion price at February 25, 2000, the first available conversion date, was
$2.93 per share. In accordance with the FASB's Emerging Issues Task Force Issue
98-5, the difference between this conversion price and the market price of $4.50
per share was reflected as additional interest expense of $1,613,013 in the
merged company's statement of operations for the quarter ended March 31, 2000.



On March 17, 2000, the Debentures were exchanged for 3,000 shares of Series A 6%
Convertible Preferred Stock (the "Preferred Stock"). The Preferred Stock has
identical terms and conditions to the Debentures, except that the holders of
Preferred Stock are entitled to cumulative dividends rather than interest,
payable quarterly in cash or common stock. At the time of conversion, the
principal balance of the Debentures was $2,246,528, and accrued interest was
$9,250. On the conversion date, Immune also netted the deferred debt issuance
costs of $440,159, previously recorded as an asset, with the carrying value of
the preferred stock. The dividends were accrued at June 30, 2000, in the amount
of $51,781.



NOTE 4 - SUBSEQUENT EVENTS



MERGER OF IMMUNE RESPONSE, INC. INTO OPTICON MEDICAL, INC. (A DELAWARE
CORPORATION)

On July 27, 2000, Immune merged into its wholly-owned subsidiary, Opticon
Medical, Inc., a Delaware corporation (referred to herein as the "Company"). The
merger was approved at the Annual Meeting of Shareholders and became effective
upon the filing of certificates of merger with the Secretaries of State of
Colorado and Delaware on July 27, 2000.



At the effective date of the merger, each outstanding share of Immune Common
Stock and each outstanding share of Immune Preferred Stock was converted
automatically into one share of Company common stock, par value $0.0001 per
share ("Company Common Stock"), and one share of Company Series A, 6%
Convertible Preferred Stock, par value $0.0001 per share ("Company Preferred
Stock"), respectively.



The Company has assumed and will continue the outstanding stock options and all
other employee benefit plans of Immune. Each outstanding and unexercised option
or other right to purchase shares of Immune Common Stock will become an option
or right to purchase the same number of shares of Company Common Stock on the
same terms and conditions and at the same exercise price applicable to any such
option or stock purchase right as of the date of the effectiveness of the
merger.



ADOPTION OF 2000 STOCK INCENTIVE PLAN



On July 27, 2000, the shareholders of the Company approved the adoption of the
2000 Stock Incentive Plan (the "2000 Plan"). The 2000 Plan is intended to
increase incentive and to encourage stock ownership on the part of (1) employees
of the Company and its affiliates, (2) consultants who provide significant
services to the Company and its affiliates, and (3) directors of the Company who
are employees of neither the Company nor any affiliate ("Non-employee
Directors").



The 2000 Plan permits the granting of stock options and restricted stock awards
(collectively, "Awards") to eligible participants. The total number of shares of
Company Common Stock available for Awards to be granted under the 2000 Plan will
consist of 1,500,000 shares. If an Award expires or is canceled without having
been fully exercised or vested, the unvested or canceled shares generally will
be available again for grants of Awards.

The 2000 Plan is administered by the Compensation and Stock Option Committee of
the Company's Board of Directors (the "Committee"). The members of the Committee
must qualify as "outside directors" under section 162(m) of the Internal Revenue
Code (the "Code"). Subject to the terms of the 2000 Plan, the Committee has the

                                      F-46
<PAGE>   82


sole discretion to determine the key employees and consultants who shall be
granted Awards, the terms and conditions of such Awards, and to construe and
interpret the 2000 Plan. The actual number of employees and consultants who will
receive Awards under the 2000 Plan cannot be determined because eligibility for
participation in the Plan is in the discretion of the Committee. The 2000 Plan
may be amended or terminated by the Board of Directors at any time and for any
reason. Certain material amendments to the 2000 Plan must be approved by the
stockholders.


If a participant engages in a certain activity that is harmful to the Company,
all outstanding and unexercised Awards may be cancelled and terminated. Awards
granted under the 2000 Plan may not be sold, transferred, pledged, assigned, or
otherwise alienated or hypothecated, other than by will or by the applicable
laws of descent and distribution.

                     INFORMATION NOT REQUIRED IN PROSPECTUS


ITEM 24.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Our Certificate of Incorporation limits the liability of directors to
stockholders for monetary damages for breach of a fiduciary duty except in the
case of liability: (i) for any breach of their duty of loyalty to us or our
stockholders; (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law; (ii) for unlawful
distributions as provided in Section 174 of the Delaware General Corporation
Law; or (iv) for any transaction from which the director derived an improper
personal benefit.

         Our Certificate and Bylaws provide for the indemnification of our
directors and officers to the maximum extent permitted by the Delaware General
Corporation Law, against all liability and expense (including attorney's fees)
incurred by reason of the fact that the officer or director served in such
capacity, or in a certain capacity for another entity at our request. Section
145 of the Delaware General Corporation Law provides generally for
indemnification of directors against liability incurred as a result of actions,
suits, or proceedings if they acted in good faith and in a manner they
reasonably believed to be in or not opposed to our best interests.

ITEM 25.  OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION

         The expenses relating to the registration of the shares of common stock
being offered hereby, other than underwriting discounts and commissions, will be

Accounting Fees and Expenses                         $  4,000

Miscellaneous Expenses                               $  2,325

Total                                                $ 22,637

ITEM 26.  RECENT SALES OF UNREGISTERED SECURITIES

         In November 1999 (and prior to a subsequent one-for-three reverse stock
split), we completed the private placement of 3,000,000 shares of common stock,
which was offered on a best efforts basis to accredited investors. The gross
proceeds from the private placement was $300,000 and were used for working
capital. We claimed exemption from registration under Rule 506 of Regulation D
of the Securities Act, and we restricted the sale of stock accordingly.

         In February 2000, following the effectiveness of the merger, we sold to
the selling stockholders $3,000,000 in principal amount of 6% Redeemable
Convertible Debentures, and warrants to purchase 300,000 shares of common stock,
for an aggregate purchase price of $3,000,000. The debentures were subsequently
exchanged for 3,000 shares of our Series A 6% Convertible Preferred Stock . The
shares of preferred stock are entitled to cumulative dividends at the rate of 6%
per annum. The warrants are exercisable at a price equal to $6.60 per share. The
preferred stock is convertible from time to time at the option of the holder
into shares of common stock at a conversion price equal to 65% of the average
closing bid price of the common stock for the 5 business days prior to
conversion. Both the preferred stock and the warrants have adjustment features
to compensate for the dilutive issuance by us of common equity (or options,
warrants or other rights convertible into or exercisable for common equity)
while the preferred stock and warrants remain outstanding. We also entered into
a Registration Rights Agreement pursuant to which we are filing this
registration statement on Form SB-2 under the Securities Act for the resale by
the selling stockholders of shares of common stock issuable on conversion of the
preferred stock or


<PAGE>   85

exercise of the warrants, and we will incur substantial penalties if the
registration statement is not declared effective within 180 days of the closing
of the sale of the preferred stock and warrants. Our net proceeds from this
transaction, after payment of fees and expenses, was approximately $2,547,265.

         In connection with the debentures, warrants, and shares of preferred
stock, we claimed exemption from registration under Rule 506 of Regulation D of
the Securities Act, and we restricted the sale of stock accordingly.

ITEM 28. UNDERTAKINGS

         The undersigned hereby undertakes:

                  A. Undertakings Regarding Amendments to this Prospectus and
                  the Registration Statement

                  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. Notwithstanding the foregoing, any increase or
                  decrease in volume of securities offered (if the total dollar
                  value of securities offered would not exceed that which was
                  registered) and any deviation from the low or high end of the
                  estimated maximum offering range may be reflected in the form
                  of prospectus filed with the Commission pursuant to Rule
                  424(b) if, in the aggregate, the change in volume and price
                  represent no more than a 20% change in the maximum aggregate
                  offering price set forth in the "Calculation of Registration
                  Fee" in the effective 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 Securities Act of 1933, 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.

                  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.

                  B. Undertaking in Respect of Indemnification. Insofar as
                  indemnification for liabilities arising under the Securities
                  Act of 1933 may be permitted to the registrant's directors,
                  officers, and controlling persons pursuant to the foregoing
                  provisions, or otherwise, the registrant has been advised that
                  in the opinion of the Commission such indemnification is
                  against public policy as expressed in the Securities Act and
                  is, therefore, unenforceable. In the event that a claim for
                  indemnification against such liabilities (other than the
                  payment by the registrant of expenses incurred or paid by a
                  directors, officers 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 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 Securities Act and will be governed by the final
                  adjudication of such issue.

         Pursuant to the requirements of the Securities Act of 1933, as amended,

SB-2 and has duly caused this Registration Statement to be signed on our behalf

Ohio, on August 22, 2000.
