               EACH UNIT CONSISTING OF ONE SHARE OF COMMON STOCK
                     AND ONE COMMON STOCK PURCHASE WARRANT
 
   
    Phytotech, Inc. ("Phytotech" or the "Company") is offering 2,000,000 units
("Units"), each Unit consisting of one share (the "Shares") of the Company's
voting common stock, no par value (the "Common Stock"), and one warrant to
purchase one share of Common Stock (the "Warrants"). The Units, the Common Stock
and the Warrants will trade as separate securities thirty days after the date of
this prospectus trading of the Units will be discontinued. Each Warrant
initially entitles the holder to purchase one share of Common Stock at a price
of $    per share (110% of the initial public offering price of a Unit). The
Warrants are exercisable at any time beginning on the Separation Date unless
previously redeemed, until the fifth anniversary of this Prospectus, subject to
certain conditions. The Company may redeem the Warrants, in whole or in part, at
any time upon at least thirty days prior written notice to the registered
holders thereof, at a price of $0.25 per Warrant, provided that the closing bid
price of the Common Stock has been at least $    (200% of the initial public
offering price of a Unit) for at least 20 consecutive trading days ending on a
date within 30 days before the date of the notice of redemption. It is
anticipated that the initial public offering price of a Unit will be between
$5.00 and $6.00.
    
 
   
    The Company has applied to have the Common Stock, Warrants and Units
approved for listing on the Nasdaq SmallCap Market under the symbols "PHYT,"
"PHYTW" and "PHYTU," respectively.
    
 
   
    The Company's independent auditors' report as of March 30, 1998, which
reports on the Company's financial statements as of and for the two years ended
December 31, 1997, states that certain factors raise substantial doubt about the
Company's ability to continue as a going concern. See "Independent Auditors'
Report" and Note 1 of "Notes to Financial Statements." The Financial Statements
included herein have been prepared assuming that Phytotech will continue as a
going concern. As of December 31, 1997 and March 31, 1998, the stockholders'
deficit was $2,148,806 and $2,639,946, respectively. Upon consummation of this
offering, assuming the sale of 2,000,000 Units at an assumed initial offering
price of $6.00, the Company's pro forma adjusted stockholders' equity as of
March 31, 1998 would be approximately $7,127,000.

                               PROSPECTUS SUMMARY
 
    THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED
INFORMATION INCLUDING THE FINANCIAL STATEMENTS, AND NOTES THERETO, APPEARING
ELSEWHERE IN THE PROSPECTUS.
 
                                  THE COMPANY
 
    Phytotech is a biotechnology company engaged in the development and
commercialization of products and services based on the control of biochemical
processes in selected plants. Phytotech currently offers waste cleanup
("bioremediation") services using plants grown under carefully controlled
conditions to absorb and dispose of unwanted metals, such as lead or uranium,
from toxic waste sites. The Company has also developed and is beginning to
market nutritionally important minerals absorbed into plants and is beginning to
develop technology for the production of high value proteins in plants.
Phytotech's goal is to develop a portfolio of proprietary and patentable
technologies based on its expertise in plant physiology, soil science, agronomy,
molecular biology and related areas and to commercialize these technologies
internally or through licensing or joint venture relationships with other
companies.
 
    All plants can, under appropriate conditions, absorb metals and other
minerals found in the soil or water in which they are grown. By carefully
selecting certain plants and managing the conditions in which they are
cultivated, it is possible to cause these plants to extract and accumulate
substantial amounts of target metals in the plant tissues. Phytotech has filed
patent applications and developed proprietary technologies involving metal
accumulation in plants for two commercial applications, phytoremediation and
nutritional supplements.
 
    Phytoremediation uses plants to accumulate large amounts of targeted heavy
metals and radionuclides (radioactive elements) in soil or water that has been
contaminated by industrial, military or other processes. The plants are grown
under carefully controlled conditions that optimize their absorption of these
metals. Sequential cropping and disposal or recycling of the plants can result
in the cost effective remediation of soil and water contaminated with heavy
metals such as lead or uranium. Phytotech has demonstrated the scientific and
economic feasibility of this application of its technology, has conducted
several field studies financed by grants, including a lead contaminated site in
Trenton, New Jersey, and is working on its initial commercial projects.
Additional commercial projects for the removal of lead and uranium are in
various stages of progress, from submitted proposals to completed agreements.
Phytotech is actively seeking additional commercial contracts and is expanding
its sales and customer support group in anticipation of business growth in this
area.
 
   
    Phytotech is also developing its metal accumulation technology by growing
select edible plants under proprietary conditions that cause the accumulation of
nutritionally important minerals such as selenium, chromium, iron, zinc and
manganese. Under cultivation using Phytotech's proprietary technology, the
plants concentrate these minerals to such high levels that they can be dried,
ground, encapsulated and used directly as nutritional supplements. Phytotech
believes that these new products may afford it a competitive advantage over
existing products for two reasons. First, Phytotech believes that its
nutritional supplements are the only botanical source of complete mineral
supplements currently available. Second, research performed by the Company and
others suggests that the bioavailability (the amount of the mineral that the
body can actually absorb and use) of mineral supplements is substantially
greater when delivered in Phytotech's mineral-rich plants than is the case with
most traditional alternatives. Phytotech has established a marketing
relationship with Arterio, Inc., a nutritional supplement distributor operating
under the trade names "Ecological Formulas" and "Cardiovascular Research", and
has shipped initial orders of chromium and selenium containing plants.
    
 
    Phytotech has recently begun research into the production of high value
proteins and nutritional chemicals in transgenic (genetically engineered)
plants. This technology, if successfully developed, could permit the production
of commercial quantities of human and other high value proteins, such as
collagen, heparin, gelatin and insulin, using genetically engineered plants that
can be cultivated and harvested to
 
                                       3
<PAGE>
   
produce the required protein. Phytotech believes that proteins grown in
genetically engineered plants may provide both biological and economic
advantages in comparison with currently available production methods. In
cooperation with independent consultants, Phytotech intends to develop a series
of carefully selected transgenic plant-based protein products for the consumer
market.
    
 
    Phytotech's ultimate goal is to be a leader in the development and
commercialization of plant-related products and technologies. Phytotech expects
to continue to perform and commission applied research in areas where its
management believes that there is good potential for commercial products, to
develop and protect a diverse portfolio of proprietary technologies, to
demonstrate the commercial feasibility of its proprietary technologies and to
exploit those technologies either directly, where such exploitation does not
require skills or other assets outside of Phytotech's scope of business, or
through licensing, joint venture or other relationships with industry partners
having complementary services and technologies.

(1) Assumes no exercise of Warrants, Representative's Warrants or outstanding
    options or warrants to purchase Common Stock. At the date of this
    Prospectus, there were issued or issuable options or warrants to purchase up
    to 924,424 shares of Common Stock at prices ranging from approximately $3.60
    to $9.00 per share (assuming an initial public offering price of $6.00 per
    Unit). Unless otherwise indicated, all information in this Prospectus
    assumes that the Underwriters' overallotment option is not exercised and
    gives retroactive effect to (i) the automatic conversion of all outstanding
    shares of the Company's Series A Convertible Preferred Stock ("Series A
    Voting Preferred Stock" or "Preferred Stock") and Non-voting Common Stock of
    the Company into an aggregate of 1,646,489 shares of Common Stock, effective
    upon the effectiveness of this offering (the "Conversions") and (ii) a
    1-for-4.5 reverse split of the Common Stock and Non-Voting Common Stock (the
    "Reverse Split") effective immediately prior to the effectiveness of this
    offering. See "Description of Securities."

STATEMENTS CONCERNING (I) THE COMPANY'S STRATEGY, (II) THE COMPANY'S EXPANSION
PLANS, (III) THE MARKET FOR THE COMPANY'S PRODUCTS, AND (IV) THE EFFECTS OF

STATEMENTS CONCERNING THE COMPANY'S OPERATIONS, ECONOMIC PERFORMANCE AND
FINANCIAL CONDITION. BECAUSE SUCH STATEMENTS INVOLVE RISKS AND UNCERTAINTIES,
ACTUAL RESULTS MAY DIFFER MATERIALLY FROM THOSE EXPRESSED OR IMPLIED BY SUCH
FORWARD-LOOKING STATEMENTS. FACTORS THAT COULD CAUSE SUCH DIFFERENCES INCLUDE,
BUT ARE NOT LIMITED TO, THOSE DISCUSSED UNDER "RISK FACTORS." IN ADDITION TO THE
INFORMATION CONTAINED ELSEWHERE IN THIS PROSPECTUS, PROSPECTIVE INVESTORS IN THE
UNITS SHOULD CAREFULLY CONSIDER THE FOLLOWING FACTORS, AMONG OTHERS, BEFORE
PURCHASING THE UNITS OFFERED HEREBY.
 
NEW TECHNOLOGIES
 
   
    The use of plants for each of the purposes for which the Company proposes to
use them has yet to be shown to be commercially viable. Although the Company has
shown that its phytoremediation techniques can reduce unwanted metals in
contaminated soil, the effectiveness of this process over a broad spectrum of
conditions has not been established. The Company has shown that targeted
minerals can be absorbed in its plants in significant quantities but has not
completed testing with respect to the speciation and bioavailability of the
targeted minerals in that form. The Company has not yet produced proteins from
plants in commercial quantities. In addition to the remaining technological
uncertainties, the novelty of the Company's technologies creates significant
uncertainty as to market acceptance. Companies introducing novel alternatives to
existing technologies generally are required to overcome initial market
skepticism, in particular when the Company introducing the technology is not a
recognized supplier to such markets. There is no assurance that the Company will
be successful in offering a commercially viable product or service or that any
such product or service, if offered, will be accepted by a broad spectrum within
its target market. See "Business--Phytoremediation" and "Business--Nutritional
Supplements."
    
 
CONTINUING LOSSES; NEED FOR ADDITIONAL FINANCING
 
   
    The Company has incurred losses since its inception and expects to continue
to incur losses at least through the end of the current fiscal year. At March
31, 1998 the Company had an accumulated deficit of $8,248,977. The independent
auditors' report expresses substantial doubt as to the Company's ability to
continue as a going concern. The timing and remaining expense associated with
bringing the Company's technologies into full commercial operation are subject
to considerable uncertainty. While the Company believes that the proceeds of
this offering will be sufficient to fund its budgeted capital requirements for
at least the next 12 months, unanticipated events could cause such proceeds to
be depleted earlier than anticipated. Management will exercise a great degree of
discretion in the application of the proceeds of this offering and a substantial
portion of the proceeds will be used to repay debt. There is no assurance that
the Company will be able to bring any of its technologies into full commercial
production with the proceeds of this offering or that additional capital
resources will be available to the Company if needed. Adequate funds to meet the
Company's working capital requirements, whether obtained through financial
markets, corporate strategic alliances, additional equity offerings or from
other sources, may not be available to the Company when required or may not be
available on terms acceptable to the Company. Any such additional financing may
result in significant dilution to existing stockholders or the issuance of
securities with rights superior to those of the Common Stock. In the event the
Company is unable to raise or borrow additional funds, the Company may be
required to curtail significantly one or more of its research and development
programs or seek additional third-party funds by relinquishing the marketing,
distribution, development or other rights to the Company's products and services
under development. See "Independent Auditors' Report," Note 1 of "Notes to
Financial Statements," "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Results of Operations."
    
 
                                       7
<PAGE>
UNCERTAINTY OF MARKET ACCEPTANCE OF PHYTOREMEDIATION SERVICES
 
   
    While the Company's phytoremediation services have been shown to be
effective in field trials, numerous factors may affect the commercial viability
of the service over a broad range of growing conditions. Factors such as
climate, soil conditions, local regulations or timing considerations may make
the Company's phytoremediation services unsuitable for a particular project.
Because of the limited testing of the service to date, there is no assurance
that it will be proven to be commercially viable over a wide range of
conditions. The market for bioremediation services generally is substantially
affected by the actions of the various regulatory organizations with
responsibility for environmental cleanup. Unless remediation is required by
regulatory authorities or as a condition of the sale or new use of a property,
the owner has little incentive to incur cleanup costs. Even where remediation is
required, bioremediation must compete with other technologies based on cost and
effectiveness. There is no assurance that the perceived need for bioremediation
will continue to support a vital market for such services. See
"Business--Phytoremediation."
    
 
UNCERTAINTY REGARDING CONSUMPTION OF NUTRITIONAL SUPPLEMENT PRODUCTS
 
   
    Although the ingredients in the Company's nutritional supplement products
are minerals for which there is a long history of human consumption, the
Company's products contain innovative ingredients or combinations of
ingredients. Although the Company believes all of its products to be safe when
taken as directed by the Company, there is little long-term experience with
human consumption of these innovative product ingredients or combinations
thereof. Although the Company performs research and/or tests the formulation and
production of its products, it has only begun to sponsor limited nutritional
studies. See "Business--Nutritional Supplements."
    
 
MANUFACTURING CAPABILITY
 
    The Company has only limited investments in manufacturing resources and will
depend substantially on contract manufacturers. There is no assurance that the
Company will be able to develop adequate manufacturing resources. Significant
time, expense and management resources would be required to develop internal
manufacturing capacity should the Company elect that alternative.
 
COMPETITION
 
   
    The Company's future success will depend in part on its ability to maintain
a competitive position with respect to evolving technologies. There is no
assurance that existing approaches or those under development or developed in
the future by others will not render the Company's current or future products or
services obsolete or noncompetitive. Moreover, traditional approaches to the
Company's chosen markets can be expected to have continuing market appeal and,
accordingly, present a serious competitive threat to the Company. The Company
competes against numerous companies, most of which have substantially greater
financial, research and development, testing, marketing and production resources
than does the Company, have established name recognition in their target markets
and are better equipped than is the Company to develop, market and manufacture
competitive products and services. Several such companies have programs, or have
initiated active product development programs, in remediation or nutritional
supplements. See "Business--Phytoremediation--Competition" and
"Business--Nutritional Supplements--Competition."
    
 
GOVERNMENT REGULATION
 
    Certain of the Company's products and services may require regulatory
approval prior to or during commercialization. There is no assurance that the
Company or its collaborative partners will be able to obtain any necessary
approvals. The effect of government regulation may be to delay marketing of new
products for a considerable or indefinite period of time, to impose costly
procedures upon the Company's activities and to provide a marketplace advantage
to companies that compete with the Company. There is no assurance any regulatory
approval for products or services developed by the Company will be granted on a
timely basis, if at all. Any delay in obtaining, or failure to obtain, maintain
or review such approvals
 
                                       8
<PAGE>
could materially and adversely affect the marketing of the Company's products
and the ability to generate product revenue and earnings. See
"Business--Government Regulation."
 
PATENTS AND PROPRIETARY RIGHTS
 
   
    The Company's success will, in part, depend on its ability to obtain patents
on its products, obtain licenses to use third party technologies, protect its
trade secrets and operate without infringing on the proprietary rights of
others. There is no assurance that the Company's pending patent applications
will issue as patents, that any issued or pending patent will provide the
Company with significant competitive advantages, or that challenges will not be
instituted against the validity or enforceability of any patent owned by the
Company or, if instituted, that such challenges will not be successful. The cost
of litigation to uphold the validity and prevent infringement of a patent is
substantial. There is no assurance that others will not independently develop
similar technologies or duplicate the Company's technology or design around the
patented aspects of the Company's technology or that the Company's proposed
technology will not infringe patents or proprietary rights owned by others,
licenses for which may not be available to the Company. Competitors of the
Company may possess or obtain patents claiming products or processes that are
necessary for or useful to the development, use or manufacture of the Company's
products. Such competitors could bring legal actions against the Company
claiming infringement by its products and processes and seeking damages and
injunctive relief. In that event the Company might be required to obtain
licenses from others to continue to develop, manufacture or market its products
or be required to cease those activities. For example, there is no assurance
that the Company will be able to obtain such licenses on commercially reasonable
terms or that the patents underlying the licenses will be valid and enforceable.
    
 
   
    The Company also relies upon unpatented proprietary technology. There is no
assurance that the Company can adequately protect its rights in such unpatented
proprietary technology, or that others will not independently develop
substantially equivalent proprietary information or techniques, otherwise gain
access to the Company's proprietary technology, or disclose such technology. See
"Business--Patents" and "Business--Phytoremediation--Technology Development."
    
 
POTENTIAL LIABILITY
 
    Various federal, state and local laws and regulations have been enacted
covering the handling and management of toxic substances and creating liability
for environmental contamination caused by them. The Company is likely to be
subject to extensive compliance review by federal, state and local environmental
regulatory authorities. There is no assurance that the Company's operations or
activities will not result in civil or criminal enforcement actions or private
actions, resulting in mandatory cleanup requirements, revocation of required
permits or licenses, denial of applications for future permits, or significant
fines, penalties or damages, any of which could have a material adverse effect
on the Company, its operations and financial condition. The Company is subject
to laws which regulate its procedures for waste treatment, storage, recycling,
transportation and disposal activities. So-called "toxic tort" litigation has
increased markedly in recent years as those injured by contamination seek
recovery for personal injuries or property damage. While these developments may
enhance the market for the Company's services, they also present a liability
exposure or risk should the Company be deemed to be responsible for
contamination or pollution caused or increased by the Company's normal
operations, including disposal of plant residue, roots or foliage, or by
negligence or other misconduct on the part of the Company.
 
   
    The Company may also be exposed to liability based on claims that its
nutritional supplements were harmful or ineffective. Although the Company does
not intend to manufacture drugs or other products with a high potential for
adverse effects, it may be exposed to a variety of claims, including claims
associated with product tampering by others. Such claims, even if lacking in
foundation, can cause material damage to the Company's reputation, can cause the
Company material expense, for example to fund a product recall, or can result in
material litigation expense. The Company expects to maintain liability insurance
when and to the extent such insurance is available on a cost effective basis.
However, there is no assurance that such insurance
    
 
                                       9
<PAGE>
   
will continue to be available to the Company on a cost effective basis or at
all. See "Business--Government Regulation."
    
 
DEPENDENCE ON, ATTRACTION AND RETENTION OF KEY PERSONNEL
 
   
    Because of the specialized nature of the Company's technology, the Company
is highly dependent upon existing management and its ability to attract and
retain qualified executive officers and scientific personnel for research and
development activities conducted or sponsored by the Company. The Company does
not currently maintain key man insurance on any of its employees. Phytotech is
currently seeking to recruit additional qualified senior operating, marketing,
scientific and technical personnel. There is intense competition for qualified
personnel in the areas of the Company's activities and there is no assurance
that the Company will be able to continue to attract and retain the qualified
personnel necessary for the development and commercialization of its products.
The Company has an employment contract with its President and Chief Executive
Officer and has consultant agreements with its key consultants. Despite the
Company's limited capital resources, the President received an increase in
annual compensation in 1996. See "Business--Personnel" and "Management."
    
 
   
POSSIBLE VOLATILITY OF STOCK PRICE; NONPAYMENT OF DIVIDENDS
    
 
   
    The market price of the Common Stock and Warrants may fluctuate
significantly based on variations in the Company's results of operations or
other factors. The Company's results of operations could be adversely affected
by a number of factors, some of which are beyond the Company's control,
including economic downturns, variations in demand for remediation technology or
nutritional supplements, changes in the mix of products sold, price changes in
response to competition, increases in the cost of raw materials and possible
supply shortages. In particular, the market price of the Common Stock could be
materially adversely affected by reports by official or unofficial health and
medical authorities and the general media regarding the potential health
benefits or detriments of products sold by the Company or of similar products
distributed by other companies regardless of whether such reports are
scientifically supported and regardless of whether the Company's operating
results are likely to be affected by such reports, as well as by consumer
perceptions regarding the safety and efficacy of the Company's remediation
services or nutritional supplements and consumer preferences generally. In
addition, the stock market in general has experienced wide price and volume
fluctuations in recent periods, and these fluctuations are often unrelated to
the operating performance of the specific issuers whose stock is affected. The
Company has never declared or paid dividends on its capital stock and does not
intend to declare or pay dividends in the future.
    
 
ABSENCE OF PUBLIC MARKET
 
    Prior to this offering, there has been no public market for the Common
Stock. Although the Company has applied to list the Common Stock on the Nasdaq
SmallCap Market, there is no assurance that an active trading market for the
Common Stock will develop or be sustained. The initial public offering price of
the Units will be determined by negotiations among the Company and the
Underwriters and will bear no direct relationship to the Company's historical
performance, assets, net worth or book value, or any other generally accepted
valuation criteria.
 
   
    To continue to be listed on the Nasdaq SmallCap Market, the Company must
continue to satisfy certain maintenance standards. If the Company is unable to
maintain the standards for continued quotation on the Nasdaq SmallCap Market,
the Common Stock and the Warrants could be subject to removal from the Nasdaq
SmallCap Market. Trading, if any, in the Common Stock and the Warrants could
thereafter be conducted in the over-the-counter market on an electronic bulletin
board established for securities that do not meet the Nasdaq SmallCap market
listing requirements or in what are commonly referred to as the "pink sheets."
As a result, an investor would find it more difficult to dispose of, or to
obtain accurate quotations as to the price of, the Company's securities. In
addition, depending on several factors including the future market price of the
Common Stock, the Company's securities could become
    
 
                                       10
<PAGE>
   
subject to the so-called "penny stock" rules that impose additional sales
practice and market making requirements on broker-dealers who sell and/or make a
market in the Company's securities and the ability of purchasers of the
Company's securities to sell their securities in the secondary market.
    
 
SHARES ELIGIBLE FOR FUTURE SALE
 
   
    Upon consummation of this offering, the Company will have 4,556,489 shares
of Common Stock outstanding. The 2,000,000 shares of Common Stock sold in this
offering and any shares of Common Stock issuable upon exercise of Warrants will
be freely tradeable without restriction or further registration under the
Securities Act of 1933 (the "Securities Act"), unless held by an affiliate of
the Company. The remaining 2,556,489 shares of Common Stock are "restricted
securities" as that term is defined in Rule 144 under the Securities Act, and
may not be sold unless such sale is registered under the Securities Act or is
made pursuant to an exemption from registration under the Securities Act,
including the exemption provided by Rule 144. Of such 2,556,489 shares,
1,028,889 are held by affiliates, with 1,026,667 shares held for longer than one
year. The remaining 1,527,600 shares are held by nonaffiliates, with 1,298,333
shares held longer than 2 years and 200,978 shares held longer than 1 year but
less than 2 years.
    
 
   
    In general, under Rule 144 as currently in effect, a shareholder (or
shareholders whose shares are aggregated) who has beneficially owned any
restricted securities for at least one year (including a shareholder who may be
deemed to be an affiliate of the Company), will be entitled to sell, within any
three-month period, that number of shares that does not exceed the greater of
(i) 1% of the then outstanding shares of Common Stock (45,565 shares based on
4,556,489 shares of Common Stock outstanding upon completion of this offering,
assuming the Underwriter's overallotment option is not exercised) or (ii) the
average weekly trading volume of the Common Stock during the four calendar weeks
preceeding the date on which notice of such sale is given to the Commission,
provided certain public information, manner of sale and notice requirements are
satisfied. A shareholder who is deemed to be an affiliate of the Company,
including members of the Board of Directors and senior management of the
Company, will still need to comply with the restrictions and requirements of
Rule 144, other than the one-year holding period requirement, in order to sell
shares of Common Stock that are not restricted securities, unless such sale is
registered under the Securities Act. A shareholder (or shareholders whose shares
are aggregated) who is deemed not to have been an affiliate of the Company at
any time during the 90 days preceding a sale by such shareholder, and who has
beneficially owned restricted shares for at least two years will be entitled to
sell such shares under Rule 144 without regard to the volume limitations
described above.
    
 
   
    As of the date of this Prospectus, options to purchase a total of 253,333
shares of Common Stock were outstanding at exercise prices ranging from $.45 to
$.68 per share, of which options to purchase 56,444 shares of Common Stock are
currently exercisable. As of the date of this Prospectus, warrants to purchase
671,091 shares of Common Stock were issued or issuable at exercise prices
ranging from approximately $3.60 to $9.00 per share (assuming an initial public
offering price of $6.00 per unit), all of which are currently exercisable.
Certain security holders of the Company have the right to require the Company to
register shares of Common Stock obtainable by them as a result of the

    LOCK-UP AGREEMENT.  The underwriters have requested that all officers,
directors and persons holding more than 5% of the Common Stock prior to this
offering, agree not to sell, offer to sell, grant any option for the sale of or
otherwise dispose of any shares of Common Stock or securities convertible into
or exchangeable or exercisable for Common Stock, without the prior written
consent of the Representative, for a period of one year after the date of this
Prospectus, except for transfers to a person's ancestor, descendants, spouse or
a trust and except for bona fide gifts or certain corporate sales or
distributions, as specified therein. No prediction can be made as to the effect,
if any, that sales of shares of Common Stock or the availability of shares of
Common Stock for sale will have on the market price of the Common Stock from
time to time. The sale of a substantial number of shares, whether pursuant to
public offerings or
    
 
                                       11

otherwise, or the perception that such sales could occur, could adversely affect
the market price of the Common Stock and could materially impair the Company's
future ability to raise capital through an offering of equity securities. There
are       shares subject to lock-up agreements.
    
 
                                USE OF PROCEEDS
 
   
    The net proceeds from the sale of the Units are estimated to be
approximately $9,940,000 (approximately $11,506,000 if the Underwriters'
overallotment option is exercised in full), assuming an initial public offering
price of $6.00 per Unit and after deducting underwriting discounts and estimated
offering expenses of approximately $         .
    
 
   
    The Company intends to use approximately $600,000 of proceeds to fund
internal research and development activities and $900,000 to fund research by
outside consultants. Of this amount, approximately $200,000 will be paid to
Rutgers, The State University of New Jersey ("Rutgers") over the next 24 months
under the Research Agreement. See "Business--Phytoremediation." The Company also
intends to use approximately $2.4 million to repay outstanding promissory notes.
The Company plans to use approximately $2.0 million of the net proceeds to fund
its sales and marketing efforts. All of the above uses have equal priority.
    
 
   
    The remaining net proceeds of approximately $4.0 million will be used for
working capital and general corporate purposes including the payment of
corporate salaries. Pending application of the net proceeds as set forth above,
the Company intends to invest the net proceeds in short term, investment grade
interest-bearing securities. The Company may reallocate the use of the net
proceeds to meet unanticipated technological or other changes in the Company's
business. The Company currently believes that its existing capital resources,
together with the net proceeds of this offering and interest earned thereon,
will satisfy the Company's capital requirements at least through the 12 months
following this offering.
    
 
   
    The following table sets forth, in tabular form, the uses of gross proceeds
described above:

                                DIVIDEND POLICY
 
    The Company has never declared or paid any cash dividends on its capital
stock. The Company intends to retain its future earnings, if any, to fund the
development and growth of its business and, therefore, does not anticipate
paying any cash dividends in the foreseeable future.
 
                                    DILUTION
 
    At March 31, 1998, the Company had a net deficit in tangible book value of
$(2,639,946) or $(1.03) per share of Common Stock. Net tangible book value
represents the amount of total tangible assets less total liabilities, divided
by the number of shares of Common Stock outstanding, after giving effect to the
Conversions and the repayment of principal and interest of approximately
$2,425,000 pursuant to the terms of certain promissory notes. After giving
effect to the sale of 2,000,000 Units in this offering at an assumed initial
public offering price of $6.00 per Unit (attributing no value to the Warrants),
and after deducting the underwriting discounts and estimated offering expenses,
the pro forma net tangible book value of the Company as of March 31, 1998 is
$7,126,717 or $1.56 per share of Common Stock. This represents an immediate
dilution of $4.44 per share to new investors. The following table illustrates
the per share dilution:

                            SELECTED FINANCIAL DATA
 
    The following selected financial data as of and for each of the years in the
two-year period ended December 31, 1997 have been derived from the financial
statements of the Company included elsewhere in this Prospectus, which have been
audited by KPMG Peat Marwick LLP, independent certified public accountants. The
selected financial data as of March 31, 1998 and for the three months ended
March 31, 1997 and 1998 have been derived from the Company's unaudited financial
statements included elsewhere in this Prospectus. In the opinion of management
of the Company, such unaudited financial statements have been prepared on a
basis consistent with the audited financial information and include all
adjustments, consisting of normal recurring adjustments, necessary to present
fairly the information set forth herein. Operating results for the three months
ended March 31, 1998 are not necessarily indicative of the results to be
expected for the year ending December 31, 1998. The selected financial data set
forth below are qualified in their entirety and should be read in conjunction
with "Management's Discussion and Analysis of Financial Condition and Results of
Operations," and the other financial information included elsewhere in this
Prospectus. The selected financial data should also be read in conjunction with
the financial statements, the related notes and the independent auditors' report
appearing elsewhere in this Prospectus. The independent auditors' report
contains an explanatory paragraph which states that the Company's recurring
losses from operations and insufficient working capital raise substantial doubt
about the Company's ability to continue as a going concern. The financial
statements and the selected financial data do not include any adjustments that
might result from the outcome of that uncertainty.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
    THE FOLLOWING DISCUSSION AND ANALYSIS SHOULD BE READ IN CONJUNCTION WITH THE
COMPANY'S FINANCIAL STATEMENTS AND THE NOTES THERETO. THE DISCUSSION OF RESULTS,
CAUSES AND TRENDS SHOULD NOT BE CONSTRUED TO IMPLY ANY CONCLUSION THAT SUCH
RESULTS OR TRENDS WILL NECESSARILY CONTINUE IN THE FUTURE.
 
OVERVIEW
 
    Since its inception in April 1993, the Company has devoted its resources to
research and development of plant-based biotechnology approaches to
environmental, nutritional and commercial protein markets, assembling a
management team, and raising capital. As an early stage company, the Company is
subject to all the risks inherent in establishing a new business, including the
risk that full-scale operations may not occur.
 
    The Company had revenues of approximately $461,000 in 1997 and anticipates
increased revenues in 1998. The Company has been unprofitable since inception
and anticipates that it will continue to incur significant expenses as it
transitions to full-scale commercial operations. The Company has begun to shift
its emphasis from research and development of its phytoremediation products to
focus on the commercialization of this technology. With respect to its
nutritional supplements products, the Company intends to increase its research
and development expenditures over the next 12 months to include preparation and
completion of laboratory testing, commencement of certain toxicology studies and
nutritional trials and other research and development expenses. Historic
spending levels are not indicative of anticipated future spending levels because
the Company is entering a period in which it may increase spending to exploit
its technology, broaden the introduction of its products into the market, and
expand manufacturing capacity. For these reasons, the Company expects to
continue operating at a loss through at least 1998. There is no assurance that
the Company will ever achieve profitability or if achieved, that such
profitability can be sustained.
 
RESULTS OF OPERATIONS
 
THREE MONTHS ENDED MARCH 31, 1998 COMPARED TO THREE MONTHS ENDED MARCH 31, 1997
 
    Grant revenue for the three months ended March 31, 1998 decreased by $5,489
or 4% to $116,942 from $122,431 for the three months ended March 31, 1997.
Commercial revenue for the three months ended March 31, 1998 increased by
$69,588 to $73,088 from $3,500 for the three months ended March 31, 1997 as the
Company transitioned to material commercial operations with an increase in
commercial sales efforts and growing industry acceptance of the Company's
technology. As a result of the foregoing factors, the Company's total revenue
for the three months ended March 31, 1998 increased by $64,099 or 51% to
$190,030 from $125,931 for the three months ended March 31, 1997.
 
   
    Research and development expenses for the three months ended March 31, 1998
decreased $114,891 or 25%, to $345,226 from $460,117 for the three months ended
March 31, 1997. The decrease was primarily attributable to substantial
completion of development efforts for the Company's phytoremediation products.
The Company expects research and development expenses to increase in the future
and to be funded primarily from the proceeds of this offering. See "Use of
Proceeds" and "Business--Nutritional Supplements--Future Development."
    
 
    General and administrative expenses for the three months ended March 31,
1998 decreased $35,382, or 10%, to $324,857 from $360,239 for the three months
ended March 31, 1997. The decrease was primarily attributable to cost controls
implemented by the Company in the period. General and administrative expenses
are expected to increase in future periods due to the hiring of additional sales
staff, expanded marketing efforts and increases in professional fees.
 
                                       16
<PAGE>
    As a result of the foregoing factors, including interest expenses of
$30,867, the Company's net loss for the three months ended March 31, 1998
decreased $178,036, or 26%, to $510,920 from $688,956 for the three months ended
March 31, 1997.
 
YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996
 
    Grant revenue for the year ended December 31, 1997 decreased by $54,636 or
17% to $270,936 from $325,572 for the year ended December 31, 1996. Commercial
revenue for the year ended December 31, 1997 increased by $122,619 or 181% to
$190,516 from $67,897 for the year ended December 31, 1996 reflecting the
commencement of material commercial operations. As a result of the foregoing
factors, the Company's total revenue for the year ended December 31, 1997
increased by $67,983 or 17% to $461,452 from $393,469 for the year ended
December 31, 1996.
 
    Research and development expenses for the year ended December 31, 1997
increased $431,256, or 24%, to $2,199,590 from $1,768,334 for the year ended
December 31, 1996. The increase was primarily attributable to increased
development efforts related to the Company's nutritional supplement products.
The Company's development efforts with respect to its nutritional supplement
products included preparation and completion of laboratory testing, preparation
for certain bioavailability studies and nutritional trials.
 
    General and administrative expenses for the year ended December 31, 1997
increased $31,806, or 3%, to $1,189,560 from $1,157,754 for the year ended
December 31, 1996. The increase was primarily attributable to the hiring of
additional personnel.
 
    As a result of the foregoing factors, including interest expense of $33,989,
the Company's net loss for the year ended December 31, 1997 increased $489,414,
or 20%, to $2,955,141 from $2,465,727 for the year ended December 31, 1997.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company has financed its operations primarily through the sale of equity
securities and the issuance of promissory notes. From inception (April 15, 1993)
through March 31, 1998, the Company raised net proceeds of approximately
$5,402,000 through private sales of equity securities and $1,867,000 from the
issuance of promissory notes. The Company had cash and cash equivalents of
$47,326 at March 31, 1998.
 
    The Company has incurred net operating losses since its inception and
expects net operating losses for at least the rest of 1998 as it continues its
commercialization efforts. The Company will incur additional net operating
losses until it can generate sufficient revenue from product sales, licenses and
other fees to fund continuing operations.
 
    While the Company has not had any operating profits, the Company believes
that its current capital resources and the proceeds of this offering will enable
it to maintain its current and planned operations for at least the next 12
months. However, there is no assurance that there will not be a change in the
Company's operations that would consume available resources more rapidly than
anticipated. The Company will need substantial funds to support its long term
product development programs. The Company has no established bank financing
arrangement and it is unlikely that the Company will establish a bank financing
arrangement in the foreseeable future. The Company's future capital requirements
will depend on many factors, including, without limitation, the progress of the
Company's commercialization efforts, research and development programs, the
progress and results of toxicology studies and nutritional trials, the timing
and costs involved in obtaining regulatory approvals and the costs of filing,
prosecuting, defending and enforcing patents.

NET OPERATING LOSS AND RESEARCH AND DEVELOPMENT CREDIT CARRYFORWARDS
 
   
    As of December 31, 1997 the Company had net operating loss ("NOL")
carryforwards of approximately $6,875,000 for federal and state income tax
reporting purposes. These loss carryforwards will expire beginning in 2000 for
state tax purposes and 2008 for federal tax purposes, if not utilized. The
Company also has research and development ("R&D") credit carryforwards of
approximately $119,000 as of December 31, 1997, which are available to reduce
federal income taxes, if any, through 2008. Changes in ownership, as defined in
Section 382 of the Internal Revenue Code of 1986, as amended, resulting from
prior sales of the Company's equity securities and the sale of the Units, could
limit the annual deductibility of a substantial portion of the NOL and R&D
credit carryforwards. See Note 10 of "Notes to Financial Statements."

                                    BUSINESS
 
OVERVIEW
 
    The Company's core technology has evolved out of research initially
performed at Rutgers on the ability of select plants, under certain conditions,
to absorb very high concentrations of various metals, either in the stems and
leaves ("Phytoextraction") or in the roots ("Rhizofiltration") of the plant. All
plants absorb minerals from the soil or water in which they are growing, but the
ability to absorb very high concentrations of particular heavy metals, such as
lead or uranium, presents the opportunity to use this process for commercial
purposes. The Company was formed to develop the commercial applications of this
technology.
 
    The emerging market for Phytotech's plant-based products and services in
processing and manufacturing presents an immediate opportunity for rapid
technical and commercial growth. Phytotech is exploring the applications of
plant biotechnology to create a unique, proprietary portfolio of products and
services. Phytotech's commercialization strategy is to capitalize on its
technologies through both the licensing and sale of superior products and
services. Phytotech currently offers waste cleanup ("bioremediation") services
using plants grown under carefully controlled conditions to absorb and dispose
of unwanted metals, such as lead or uranium, from toxic waste sites. It has also
developed and is beginning to market nutritionally important minerals absorbed
in plants and is beginning to develop technology for the production of high
value proteins in plants.
 
    Phytotech's ultimate goal is to develop a portfolio of proprietary
technologies based on its expertise in plant physiology, soil science, agronomy,
molecular biology and related areas and to commercialize these technologies
internally or through licensing or joint venture relationships with other
companies. Phytotech expects to continue to perform and commission applied
research in areas where its management believes that there is good potential to
develop commercial products. The Company intends to protect its diverse
portfolio of proprietary technologies, demonstrate their commercial feasibility
and market these technologies either directly, where such sales do not require
skills or other assets outside of Phytotech's scope of business, or through
licensing, joint venture or other relationships with industry partners having
complementary services and technologies.
 
PHYTOREMEDIATION
 
    TECHNOLOGY.  The term phytoremediation refers to the use of plants to treat
contaminated soil and water. The Company has demonstrated the feasibility of
phytoremediation in a number of field trials and several commercial projects
which have led to the development of two distinct approaches to cleanup:
 
    PHYTOEXTRACTION:  the use of metal-accumulating plants to transport and
    concentrate metals from the soil into the leaves and stems;
 
    RHIZOFILTRATION:  the use of plant roots to absorb, concentrate and
    precipitate toxic metals from polluted water.
 
    By screening and selection procedures focused on known, well characterized
crop species, Phytotech has identified superior metal-accumulating plant lines
for phytoextraction. The Company has shown that such plants can accumulate lead,
uranium, cesium, strontium, chromium, zinc, selenium, manganese, calcium, iron
and magnesium from soils into the above-ground, harvestable shoots.
 
    Phytotech has investigated several approaches to increasing the
phytoextraction capacity of plants. The Company screened numerous plants in
order to isolate high-performing cultivars and identified soil
 
                                       19
<PAGE>
amendments and other processes that increase the efficiency of phytoextraction.
The phytoextraction process currently employed by the Company is shown below:
 
                    THE PHYTOEXTRACTION PROCESS IN THE FIELD
 
   
                                  [CHART]
 
    In the Company's rhizofiltration process, hydroponically cultivated plants
remove heavy metals from water and concentrate them in the roots. Once the water
has been cleaned, the plants can be easily removed, replaced with fresh plants
at low cost, and the process continued. The plants containing heavy metals can
be disposed of or treated to recycle the metal. In addition to lead, plant roots
can effectively remove uranium, strontium, cesium and zinc to concentrations
within accepted state and federal water standards. The plants accumulate lead,
uranium, strontium, cesium and zinc at a rate sufficient to reduce the soil
concentrations to below regulatory standards within one to four growing seasons,
depending on the starting constituent concentration and depth of the
contaminated zone. The plants are grown to a density of approximately one ton
per acre per cropping to reach the uptake performance.
    
 
                                       20
<PAGE>
   
    The plants containing the metals can be dried, baled and disposed of as
hazardous waste in a permitted hazardous waste landfill. In some circumstances,
the metal containing plants can be smelted or chemically treated to remove the
metal for recycling, and the plant residue disposed of as non-hazardous waste.
    
 
   
    TECHNOLOGY DEVELOPMENT.  The initial theoretical work on phytoremediation
was performed by scientists at Rutgers. Rutgers and the Company executed a
Research Agreement on November 19, 1993 (as amended, the "Research Agreement")
to perform certain studies and field trials for the phytotreatment of heavy
metals. The initial term of the Research Agreement was for a three year period.
As currently extended, the Research Agreement expires August 13, 2002 but may be
extended, renewed, or amended by the mutual written agreement of both parties.
The Company agreed to reimburse Rutgers for all direct and indirect costs during
the initial three-year term, and has agreed to reimburse Rutgers for certain
additional costs up to $500,000. The Research Agreement may also be terminated
by either party without further financial obligation by giving at least ninety
(90) days written notice.
    
 
   
    Legal title to intellectual property conceived or discovered in the
performance of the Project is vested in Rutgers, subject to the terms and
conditions of the Research Agreement and the Company's license rights described
below. Rutgers must promptly notify the Company once it has identified any
potentially valuable intellectual property conceived and/or made during the term
of the Research Agreement. If the Company directs that a patent application or
application for other intellectual property protection (i.e. copyrights, Plant
Variety Protection Certificates, and plant patents) be filed, Rutgers must
promptly prepare, file and prosecute such U.S. and foreign application(s) in
Rutgers' name. The Company will bear all costs incurred in connection with the
preparation, filing, prosecution and maintenance of U.S. and foreign
application(s) directed to such intellectual property. If the Company does not
request Rutgers to file for protection of intellectual property in any country,
or decides to discontinue the financial support of any patent prosecution,
Rutgers may pursue whatever course it deems necessary to protect its
intellectual property, and Rutgers will have no further obligation to the
Company to option or to license with regard to that country. The Company and
Rutgers executed an Exclusive License Agreement in September 1997. Under the
Exclusive License Agreement, Phytotech is obligated to pay a royalty to Rutgers
equal to 2 1/2% of revenues from projects employing the licensed technology
(subject to increases to 3.5% and 5% at annual revenue rates of $250 million and
$500 million, respectively) and is entitled to the exclusive use of the licensed
technology subject to certain non-commercial exceptions. The Exclusive License
Agreement covers the life of the patents comprising the technology, subject to
earlier termination for breach of the Exclusive License Agreement.
    
 
    FIELD TRIALS.  Phytotech has conducted field trials over the last three
years to demonstrate metal accumulation from soil and water on selected sites.
These trials have provided the Company with the opportunity to validate the
technology, educate the public and accrue on-site experience. Current field
trials are designed to improve the performance of phytoextraction with lead and
uranium.
 
   
    In 1996 and 1997, Phytotech conducted a field trial on a lead-contaminated,
abandoned industrial site in Trenton, New Jersey. Six croppings of plants over
two growing seasons on this site have, to date, reduced the lead contamination
on 75% of the treated area to within New Jersey residential standards. This site
is the location of the Superfund Innovative Technology Evaluation Program the
Company is conducting in collaboration with the United States Environmental
Protection Agency ("EPA"). Phytoextraction results of lead from soil at the
Trenton test plot is shown below. The New Jersey residential standard for lead
in soil is 400 parts per million ("ppm") or less.

    MARKET OPPORTUNITY.  The EPA and various state environmental agencies
determine the requirements for, and standards applicable to, the clean-up and
remediation of contaminated property in the United States. Published reports
estimate that there are more than 30,000 sites in the U.S. requiring hazardous
waste treatment services. The Company believes heavy metals comprise a
particularly problematic component of this market, because no permanent, low
cost solutions exist for remediation of metal contamination. Phytotech is
applying its phytoremediation technology to the cleanup of such metal
contaminated sites, a U.S. market estimated by the EPA to be $35 billion over
the next five years. Based on these assumptions, the Company believes that the
potential U.S. market for its technology in treating heavy metals as the sole
contaminant on a site is of an order of magnitude of approximately $100 million
per year. Expansion of this technology to the treatment of sites contaminated
with a mixture of heavy metals and hazardous organic compounds could increase
the market to approximately $600 million per year. As a practical matter,
Phytotech can expect to be a serious candidate for only a small fraction of
these markets. Phytotech's approach is to penetrate the existing market by
targeting sites that can currently only be treated using very costly removal and
burial technology and that offer attractive pricing and liability
 
                                       22
<PAGE>
   
management options. Phytotech's experience leads it to believe that its
technology is appropriate in approximately one out of four projects in which a
site analysis has been completed. However, there is no assurance that any
predetermined percentage of sites meeting Phytotech's target critera will in
fact be suitable sites for Phytotech's technology.
    
 
   
    The emerging radioactive contamination treatment market, estimated at $250
billion over the next 70 years, represents a substantial domestic and
international opportunity. Radionuclides are elements whose nuclei are unstable
and transform into other elements through radioactive decay. This process
releases ionizing radiation that can damage or destroy living cells. A variety
of health risks, particularly various forms of cancer, are associated with
exposure to radionuclides. The Company believes that conventional technology
(excavation and landfill) is significantly more expensive than a plant-based
treatment. The Company is currently field testing and exploring the commercial
application of licenses for its technology to the remediation of these sites.
    
 
    TARGET CUSTOMER GROUPS.  The Company is targeting its marketing efforts
toward:
 
    - Owners of contaminated sites in the private and public sectors identified
      through lists published by the EPA, state and local environmental
      regulatory agencies as well as through established relationships with
      industry;
 
    - Large companies with significant environmental liabilities, including many
      Fortune 500 companies;
 
   
    - Companies in industries known for toxic-metal pollution problems, such as
      metal smelters, primary and secondary metal manufacturers, scrap metal
      recyclers, paint manufacturers, battery recycling and production
      facilities, chemical and petrochemical manufacturers, automobile
      manufacturers, utility companies, transportation, the mining industry and
      landfill operators.
    
 
    COMMERCIALIZATION STATUS.  Phytotech's phytoremediation technology has been
available on a commercial scale since mid-1997. The Company has demonstrated the
effectiveness of its technology in the field in several demonstration and pilot
scale programs since 1995. Phytotech has entered into several commercial
contracts for the 1998 phytoremediation season and has initiated clean-ups under
state and federal regulated programs for private and public sector clients.
 
    To date, the Company has been awarded nine contracts or subcontracts for
feasibility-scale studies, a full-scale remediation under the EPA Region I
voluntary corrective action program, and two full-scale treatment projects.
Additionally, a major electric utility is evaluating the technology for use as a
process application to prevent the build-up of metals in its wastewater
sprayfields. Revenues for commercial phytoextraction technology projects totaled
$190,000 in 1997. Current funding commitments for work to be performed in 1998
under grants and contracts exceeds $600,000.
 
    The Company has entered into a Cooperative Research and Development
Agreement ("CRADA") with the EPA to evaluate the efficacy of the Company's lead
removal phytoremediation technology at a contaminated site as part of the EPA's
Superfund Innovative Technology Evaluation ("SITE") program. The EPA's review is
expected to be concluded in 1998 and a report on the outcome of the study issued
thereafter. The Company believes that approval by the EPA would enhance the use
of the technology in the Superfund program.
 
    The Company is pursuing both domestic and international markets through
licensing arrangements with third parties. The Company believes that the
European market is equal to, and growing more rapidly than, the U.S. market.
Because phytoremediation is based on established agricultural practices and an
easily transferable applications technology, all of the necessary materials can
be manufactured at or near the treatment site. The Company is expanding its
market overseas through marketing arrangements with UI USA, Inc., a subsidiary
of Credit Agricole. UI USA, Inc. has arranged a technology evaluation agreement
for European applications of the Company's technology between Phytotech and ATE,
Inc., a subsidiary of Rhone Poulenc. Additionally, Phytotech has recently been
awarded a contract for a rhizofiltration treatability study of arsenic and
uranium contaminated groundwater from the Ammon-Zarga basin in Jordan.
 
                                       23
<PAGE>
    COMPETITION.  The diversity of technological approaches for hazardous waste
remediation has resulted in a fragmented industry. In 1996, the top 30
remediation companies reported combined treatment revenues of $4.5 billion from
U.S. projects, approximately half of the estimated $9 billion spent annually in
the U.S. for hazardous waste treatment. Standard options for the treatment of
soils contaminated with metals includes excavation and disposal in landfills,
stabilization or capping, which consists of covering the site with an
impermeable layer, such as asphalt or concrete. Each of these options does not
eliminate the liability, is costly and requires on-going operations and
maintenance. Phytotech's technology combines cost advantages with on-site
treatment or leaving cleaned soil in place. The high concentrations of metals in
Phytotech's plant residues may permit metal recycling, which could eliminate or
reduce the need for landfilling of hazardous wastes, and could eliminate the
client's liability, rather than simply moving it to another location. However,
Phytotech's technology may not be suitable in certain soil conditions, in areas
with relatively short growing seasons, where rapid remediation is required or
under other specific circumstances.
 
    Several research institutions or government agencies, such as the United
States Department of Energy ("DOE"), the United States Department of Defense
("DOD"), and the United States Department of Agriculture ("USDA"), have
phytoremediation programs. The Company believes it has the largest and most
advanced soil phytoremediation business in the world.
 
   
    The following table sets forth certain information relating to
phytoextraction and other principal technologies used in soil remediation:

Many other factors affect the relative advantage of the various treatment
alternatives, including the particular characteristics of each site. The Company
believes that each of the above-listed treatment methods may be suitable for
certain sites and not for others.
 
    Competitive methods of soil treatment are primarily practiced by engineering
and remediation services companies that offer excavation and off-site
landfilling of contaminated soil as hazardous waste. This approach denudes the
site of all contaminated topsoil and is cost prohibitive for large areas.
Landfills charge unloading (tipping) fees of $100-400 per ton. This work is
highly price competitive with low profit margins. The Company believes that many
heavy metals-contaminated sites are best remediated by a combination of
phytoextraction and conventional excavation and landfill. Accordingly,
Phytotech's strategy is to grant technology licenses and team with a number of
these contractors. The use of phytoremediation may provide the opportunity for
many sites to move forward that were previously thought to be cost prohibitive
and could allow municipalities to address more contaminated sites at reduced
cost.
 
NUTRITIONAL SUPPLEMENTS
 
    TECHNOLOGY.  Phytotech's original discoveries of the ability of selected
plants to take up high levels of target metals led the Company to evaluate
plants that would accumulate minerals that are essential trace nutrients. In
order for a plant to be a practical source of mineral supplements, it must be a
recognized, edible species and capable of accumulating large amounts of minerals
in its edible parts. Mineral and vitamin supplements have traditionally been
available as capsules or tablets. The Company has developed plants containing
targeted minerals in such concentrations that the minimum daily adult
requirements can be provided in a single tablet or capsule by reducing the plant
itself to powder form and encapsulating the powder. The plant is cultivated
under controlled conditions so that the metal uptake is specific and the
 
                                       24
<PAGE>
plant does not also accumulate undesirable minerals such as lead, arsenic or
cadmium. The Company and outside collaborators have identified edible plants and
cultivation conditions capable of producing the required concentrations of the
minerals iron, zinc, manganese, selenium and chromium in the edible parts of the
plants.
 
    The following table provides certain information with respect to the mineral
content of the Company's selected plants as compared to several "mineral rich"
vegetables:

    BIOAVAILABILITY.  Mineral supplements are available to the consumer as
organic or inorganic salts of metals manufactured primarily by the chemical
industry. Minerals in these forms are difficult for the body to absorb and use.
Some minerals, such as selenium and chromium, are also offered as a complex with
yeast, which makes them easier for the body to absorb. The bioavailability, or
amount actually absorbed by the body, of minerals in supplements has been a
long-standing concern, and forms of the minerals that are shown through testing
to be more bioavailable are highly valued by consumers. The Company believes
that its plant-based minerals may have high bioavailability because the minerals
are in a form that is biologically available to the plants and therefore may be
similarly available to other organisms. Bioavailability is an important property
since the value of the mineral is wasted if it is not taken up and absorbed by
the body. The Company has arranged for bioavailability testing with outside
laboratories and also conducted its own testing. Preliminary testing of the
Company's plants in its laboratories has indicated that its plant-based sources
of iron, zinc, chromium and selenium are among the most bioavailable forms of
these minerals when compared with other commercially available supplements.
 
    The Company has executed a Cooperative Research and Development Agreements
(CRADA) with the USDA laboratory at Cornell University, Ithaca, New York and is
negotiating a similar agreement with the USDA nutritional lab at The Presidio,
San Francisco focused on the measurement of mineral bioavailability in the
Company's plants. The Cornell lab has proposed to evaluate bioavailability IN
VITRO using a method based on transformed human intestinal monolayer cells. The
Presidio lab plans to conduct human nutritional studies with volunteers. The
Company expects these studies to be completed in 1998.
 
   
    SPECIATION.  The Company believes that in order to establish a solid
scientific basis for the nutritional value of its plant-based supplements, it is
important to identify the speciation, or chemical form of the minerals in the
plants. One of the Company's scientific consultants has begun to characterize
the speciation of minerals in fresh and dried plants. The speciation of selenium
has been completed, and the results of this work are expected to be published in
1998. The speciation of chromium has been partially characterized, and the
Company anticipates its consultants will characterize all of the minerals taken
up by its plants.
    
 
    FUTURE DEVELOPMENT.  Selenium accumulation by plants in the crucifer family,
of which broccoli and several of the Company's plants are members, combines the
antioxidant and anticarcinogenic aspects of
 
                                       25
<PAGE>
selenium and organoselenium compounds with natural organic antioxidants found in
cruciferous plants. Cruciferous plants and plant extracts are currently sold as
nutritional supplements by others because these plants are said to contain
particular compounds that have been linked to improved immune functions. The
Company believes that organic antioxidants are also present in its plants and is
developing the capability to identify and measure these compounds. The Company
is planning to measure the antioxidative effect of organoselenium enriched
supplements. Phytotech has recently submitted a proposal in collaboration with
two academic research institutions to the National Cancer Institute to evaluate
the antioxidant and anticarcinogenic properties of its selenium accumulating
cruciferous plants.
 
    MARKET OPPORTUNITY.  Recent estimates by THE VITAMIN RETAILER place the
annual sales of nutritional supplements worldwide at $20 billion in 1996.
According to a 1996 industry survey, the U.S. market totaled $6.5 billion,
generated through sales at 38,000 retail outlets and with an annual growth rate
of 15%. Vitamin and mineral supplements accounted for 49% of retail sales, and
single mineral supplements comprised 10% of such sales.
 
    The Company's approach to the development of its nutritional supplements
includes carefully controlled cultivation conditions, characterized
bioavailability and quantified chemical forms of the minerals in its plants at
consistent levels and quality standards. The Company will seek to establish the
following characteristics for its botanical mineral supplement products:
 
    - Batch to batch consistency;
 
    - Precise and carefully controlled quantities of active ingredients;
 
    - Standardized quality;
 
    - Solid scientific basis for the benefits of the supplements; and
 
    - Patented production methods.
 
    The Company has identified five nutritionally important minerals that can be
accumulated in its select plant cultivars at sufficient concentrations to supply
100% of the RDA or recommended daily intake of these supplements. Other mineral
and organic supplements are being evaluated by the Company as priorities allow.
The minerals under development include:
 
    SELENIUM.  Selenium is an essential trace mineral and is present in all the
tissues of the body as an activating component of the enzyme glutathione
peroxidase, which has been shown to protect cells from free radical damage.
Intake of 50-70 mg ("micrograms") per day is recommended for good health, but
even this small amount of selenium can be lacking in many diets. Recently,
selenium from a yeast source has been linked in a study by the Arizona Cancer
Center to a reduction in the incidence of and mortality from cancers of the
colon, prostate and lung. The administered dose of selenium in this study was
relatively high compared to multivitamins which typically contain 50 mg
selenium.
 
    CHROMIUM.  Chromium is primarily involved in the metabolism of glucose and
the synthesis of proteins. Because of its role in insulin production and glucose
regulation, chromium depletion has been implicated in hypercholesterolemia and
may play a role in the control of glucose levels. Chromium picolinate is
promoted by others as an important part of several weight-loss products, and
some studies support the use of dietary chromium as a weight loss aid.
 
    IRON.  Every cell in the body contains and requires iron. When its supply is
low, diverse symptoms and disorders may result. Iron is required in relatively
high doses to maintain proper nutrition. Of all the nutrient allowances, the
allowance for iron is the most difficult to obtain from dietary sources, which
is why iron is the most common single mineral deficiency in the world.
 
    The bioavailability of iron in supplements has historically been a problem.
The most commonly prescribed iron supplements for women of child-bearing years
are poorly absorbed and can cause
 
                                       26
<PAGE>
gastrointestinal upset. Phytotech has preliminary data indicating that the iron
in its hyperaccumulating crucifers may be more bioavailable than other
commercially available supplements. The Company is planning a human nutritional
trial in collaboration with the USDA to document the benefits of PHYTOIRON-TM-
as a "natural" iron supplement.
 
    ZINC.  Zinc is an essential trace mineral that is required in relatively
high doses and it is among the best selling individual trace minerals in the
health food industry. Zinc is an essential component of enzymes for various
metabolic processes. Daily intake of zinc lozenges containing 13 mg of zinc has
also been reported to ameliorate the symptoms of the common cold. Despite the
essential nature of zinc, the human body does not store this mineral, so the
body is dependent upon a continual external supply.
 
    MANGANESE.  Manganese is best known as a component in various enzymes,
including those involved in the metabolism of protein, lipids and carbohydrates.
Manganese is poorly absorbed by the body and is scare in processed foods.
Manganese does not have an RDA, but is included in a number of mineral
supplement products. Manganese is promoted by nutritional supplement suppliers
as having a role as an antioxidant and in maintaining healthy bones.
 
   
    COMMERCIALIZATION STATUS AND PROSPECTS.  The Company has completed pilot
scale studies for iron, zinc, selenium and chromium uptake by its plants. The
Company commenced commercial scale production of selenium and chromium
containing plants in the first quarter of 1998. The Company expects to proceed
with the commercial production of iron, zinc and manganese nutritional
supplements as resources permit. The Company is also evaluating several other
nutritional minerals as candidates for a plant-based source. Phytotech has
entered into a marketing arrangement with Arterio, Inc., a distributor of
nutritional supplements that markets products under the brand names Ecological
Formulas and Cardiovascular Research, to market its selenium and chromium
supplements and antioxidant skin care cream. Phytotech contracts with an outside
greenhouse contractor to produce bulk product which is then shipped to a Food
and Drug Administration ("FDA") approved manufacturing facility for tableting,
encapsulating, packaging and labeling. Ecological Formulas provides marketing,
distribution and sales coordination of the plant material as nutritional
supplements through its own sales organization and also to other distributors
and marketers of nutritional supplements.
    
 
    Phytotech may also choose to sell bulk tablets or capsules to companies
serving the nutritional supplement industry through the following established
distribution channels:
 
    MAIL ORDER.  These customers are reached through print and electronic
advertising, including through sites on the internet. Several companies
specialize in direct sales to consumers through mail order advertising.
 
    MULTILEVEL/NETWORK MARKETING.  These organizations, such as Amway, Shaklee,
Celltech and Herbalife sell products that generally cannot be obtained in retail
stores.
 
    INDEPENDENT RETAILERS OF NUTRITIONAL SUPPLEMENTS.  These retailers include
privately owned health food stores, of which approximately 7,000 existed in the
U.S. in 1996. In addition, nutritional supplements are sold widely in
pharmacies, wholesale outlets and clubs and supermarkets.
 
    OTHER DISTRIBUTORS.  These distributors could include private label
wholesalers such as General Nutrition, Nature's Sunshine Products, Weider
Nutrition, Twinlabs, Nature's Bounty, Rexall Sundown, and also fitness centers,
health practitioners and dispensing nutritionists.
 
    COMPETITION.  The nutritional supplement industry is fragmented and includes
several large manufacturers along with many smaller producers and distributors.
While a few of the distributors are vertically integrated, most distributors
contract with manufacturers for finished products.
 
    A large number of manufacturers produce mineral supplements for all
marketing outlets. Many of these mineral supplements are inexpensive to
manufacture, but have limited mineral bioavailability, which
 
                                       27
<PAGE>
can reduce their effectiveness. To attempt to address this problem, advanced
formulas containing chelated or organically complexed mineral supplements have
been introduced to the market during the last few years. As far as the Company
is aware, no other company offers plant-based nutritional supplements as a
source of dietary minerals, because plants ordinarily do not contain sufficient
quantities of minerals to be effective supplements.
 
COMMERCIAL PROTEIN PRODUCTION
 
    TECHNOLOGY.  The Company has received funding from the USDA under a Small
Business Innovative Research grant to develop transgenic plants, which are
plants capable of making proteins based on genes that are not native to the
plant, and is expanding this effort into a core technology for the expression of
commercially useful proteins in crop plants. Phytotech and its outside
collaborators believe they can develop transgenic crop plants to produce
valuable proteins for selected niche markets at a significant cost savings over
current sources.
 
    Recent developments in the application of plant molecular biology have made
it easier to develop transgenic plants that can inexpensively synthesize
desirable protein products. Applications of these and other methods to create
transgenic plants capable of producing valuable commercial proteins could offer
multiple, significant advantages over conventional fermentation and cell culture
techniques. These advantages could include lower production costs, easier
production scale-up and improved safety characteristics.
 
    Historically, it has been difficult to obtain stable levels of foreign
proteins in plants. In addition, certain plant characteristics complicate
protein recovery and purification processes. Rapid, large scale clonal
propagation of many plant species is now feasible. Evidence of stable, high
level expression of a bacterial gene in the leaves, roots and tubers of
transgenic potato plants has been published by the Company's collaborators.
These results suggest that this core technology can be developed to produce
large amounts of selected proteins in targeted organs of crop plants. Further
work has also shown that foreign proteins can be stably produced and the protein
accumulated in plant seeds.
 
    The Company believes production of proteins through transgenic plants offers
the potential for substantial cost savings, because novel genetic engineering
methods may allow the initial low cost advantage to be carried downstream
through purification, yield and recovery. Certain safety issues may also favor a
plant or plant cell culture based approach. A plant-based approach eliminates
the presence and risk of mammalian infectious agents. Proteins, such as heparin,
gelatin, collagen, insulin, as well as drug manufacturing proteins, such as
brain-heart infusion, bovine serum albumin, and fetal calf serum, all have
mammalian sources. There is a growing concern that proteins derived from
mammalian sources present the possibility of transmission of retroviruses and
other infectious agents. The tests for these infectious agents are complex and
their inactivation or removal is difficult. Phytotech and its collaborators are
presently engaged in developing plant-based proteins lacking these infectious
agents.
 
    MARKET OPPORTUNITY.  The potential market for commercial proteins from
transgenic plants is estimated by the Company to be at least $300 million
annually. Collagen is an example of a protein that may present a market
opportunity for plant-based manufacture. Collagen has both therapeutic and
cosmetic applications. Derivatized bovine collagen is the current source for
cosmetic use, plastic surgery, wound and bone healing, and wrinkle removal by
transdermal injection and had worldwide sales in 1997 in excess of $70 million.
Human collagen produced in a transgenic plant or plant organs might present
advantages over the bovine material. The stringent purification and analytical
procedures required for therapeutic use of bovine collagen could be reduced with
a plant-derived material. The absence of potential or perceived mammalian
pathogens in plant-derived collagen would simplify purification, testing and
validation procedures and could reduce manufacturing costs. Approximately 3% of
the human population is allergic to derivatized bovine collagen. A plant based
collagen source may eliminate this problem.
 
    COMMERCIALIZATION STATUS.  Phytotech has engaged in preliminary work toward
the development and commercialization of efficient, cost effective methods of
protein production using transgenic plants. The
 
                                       28
<PAGE>
Company is seeking to augment its internal efforts by licensing advanced
technology. Contingent on the closing of this offering, Phytotech has negotiated
an exclusive, worldwide license with an internationally recognized research
organization to use certain proprietary technology for the cost effective
production and commercialization of selected proteins in transgenic plants.
 
    If the preliminary development work in which the Company is engaged is
successful, the Company intends to use these transgenic plants to manufacture a
series of commercial proteins at significantly reduced cost. The Company plans
to cultivate, harvest and analyze the transgenic plants. Recovery and
purification of the protein product will be performed by outside manufacturers.
Phytotech intends primarily to provide the purified proteins as a bulk product
for resale. For selected products, the Company may market directly to consumers.
 
    Production of proteins using transgenic plants may offer manufacturing cost
advantages for products having moderate to high unit prices and markets in
quantities of tens to thousands of kilograms per year. These include proteins
that have dietary, catalytic or cosmetic applications with expired or dated
intellectual property protection. Some proteins are good potential targets
because both cost and perceived safety issues favor a plant-based approach.
 
    CUSTOMER GROUPS.  Phytotech plans to manufacture transgenic plants and
market plant-based proteins with moderate to high value that address niche
markets of $5 to $100 million in annual sales. Potential customer groups for the
Company's planned commercial protein products include:
 
    - Cosmetics formulators for proteins such as collagen and elastin;
 
    - Specialty food companies that use large quantities of proteins such as
      rennet in cheese making, pectinases and amylases in food processing and
      brewing and malting enzymes;
 
    - Companies producing protein sweeteners;
 
    - Grain processing companies that use enzymes for starch liquefaction and
      saccharification; and
 
    - Textile companies that use enzymes for desizing and fabric finishing.
 
    COMPETITION.  Large companies with extensive experience and research
programs in transgenic plants include Monsanto, DuPont, Novartis, DowElanco, and
Pioneer. The research programs at these companies are primarily focused on
applications associated with large markets, such as pesticide-containing and
herbicide-resistant transgenic crop plants grown for traditional uses. Mid-sized
firms such as DNA Plant Technology also focus on producing transgenic plants
that appeal to mass markets. Some small, privately held companies such as
BioSource and Prodigene have research programs involving the production of high
value proteins in transgenic plants, which may be directly competitive with
Phytotech's product development plans.
 
TECHNOLOGY DEVELOPMENT
 
    Phytotech is developing new technologies using its own resources and
expertise and by entering into cooperative arrangements with other
organizations. Funding for new technology development has come both from sales
of the Company's equity securities and promissory notes and from grants received
by the Company.
 
    RESEARCH GRANT FUNDING.  Some of the Company's research and development
activity is partially or fully underwritten by outside competitive grant
funding. This support validates the quality and helps defray the costs of
research and development efforts. The Company will continue to pursue additional
grants and contracts and certain Company personnel are actively writing grant
proposals. The Company anticipates that federal and state grants will continue
to defray a portion of the development and commercialization costs. Since
inception, the Company has completed seven funded projects totaling $811,000,
has five
 
                                       29
<PAGE>
ongoing projects with approximately $950,000 in total grant support and has five
proposals pending to various states and federal agencies.
 
    CONTRACTS AND TEAMING AGREEMENTS.  The Company has entered into and is
negotiating teaming and technology development agreements with public and
private organizations to further the commercial use of its products and
services. The Company has executed joint development and teaming agreements with
ATE, Inc. in France through its representative UI USA, Inc., and various
environmental consultants. The Company is negotiating similar agreements with
others to market its services.
 
PATENTS
 
   
    Phytotech has established an aggressive patent program to protect its
technology and intellectual property. In all countries it deems appropriate, it
holds the exclusive rights to inventions disclosed in three issued United States
patents covering the metal accumulating technologies. Exclusive rights to these
patents have been assigned to the Company. The U.S. government retains certain
rights to some issued patents, including a royalty-free, non-exclusive license.
The Company does not expect the retention of these rights to impact materially
on its patent protection or exclusivity in commercialization.
    
 
   
    The Company believes that the three issued patents will enable it to
establish an advantage position on the use of terrestrial plants for the
accumulation of metals. Phytotech continues to enhance these scientific
developments by supporting outside research and through work in the Company's
own laboratory. Three additional patent applications have been filed by Rutgers
covering improvements and new concepts arising from the supported research. A
Notification of Allowance has been issued for one of these patent applications.
The Company has rights to exclusive, worldwide licenses to the inventions
covered by these applications. Six U.S. patent applications arising from
discoveries owned solely by the Company have also been filed. Notifications of
Allowance have been issued for two of these patent applications. The Company
expects that future improvements and discoveries will be covered by additional
patent applications.
    
 
GOVERNMENT REGULATION
 
    The Company's products and services are subject to extensive regulation by
various governmental authorities. The Company's products may be regulated by
EPA, FDA and USDA and by various state or foreign regulatory bodies. The effect
of government regulation may be to delay marketing of new products for a
considerable or indefinite period of time, to impose costly procedures upon the
Company's activities and to provide an advantage to companies that compete with
the Company.
 
REGULATION OF PHYTOREMEDIATION
 
    The Company does not anticipate that it will be subject to the Resource
Conservation and Recovery Act ("RCRA"), as amended, as a "Treatment, Storage or
Disposal Facility" (a "TSD" facility). However, certain treatment systems that
the Company may elect to operate may require it or its customers to obtain a TSD
facility permit from the EPA (or a state authorized to run its own RCRA program)
before placing treatment systems into operation. Obtaining a TSD facility permit
can be a time-consuming and expensive process, requiring considerable
documentation, including process information, waste specifications and
information regarding compliance assessments, security procedures, emergency
plans and insurance. The TSD facility permitting process also requires local
public hearings. Where there is local public opposition to the siting of a
facility, obtaining a TSD facility permit can take more than a year, and in some
cases up to two to four years, if the permit is granted at all. There has been
public concern regarding the use of genetically modified plants in the
environment and there could be public opposition to the use of genetically
modified plants for toxic metal remediation. Delays in obtaining a TSD facility
permit or any other required permits could affect the ability of the Company to
receive revenues from the use or sales of its products, once developed, and such
delays could materially adversely affect the financial condition of
 
                                       30
<PAGE>
the Company given its limited financial resources. The Company's products may
also be subject to other environmental regulations regarding their operation,
including mandatory removal levels and prohibitions on the release of certain
levels of hazardous wastes in the exit stream of the Company's systems.
 
    Additionally, other permits may be required from the EPA and various state
and local agencies in connection with the use or operation of the Company's
products. The federal and state environmental laws, rules and regulations
regulating the Company's current or proposed business operation are complex,
subject to varying interpretations and are rapidly changing and evolving.
Compliance with these laws, rules and regulations by the Company is expected to
be time-consuming and expensive. Any failure by the Company to comply with the
requirements of these environmental laws regulating its activities, even if
unintentional, could give rise to liabilities, penalties or fines that could
materially adversely affect the financial condition of the Company and could
adversely affect its reputation in the industry.
 
REGULATION OF NUTRITIONAL SUPPLEMENTS
 
    In the United States as well as in any foreign markets in which the Company
may sell its products, the Company will be subject to regulations regarding (i)
the formulation, manufacture, packaging, labeling, distribution, importation,
sale and storage of the Company's products, and (ii) product claims and
advertising.
 
    The formulation, manufacture, packaging, storing, labeling, advertising,
distribution and sale of the Company's products are subject to regulation by
federal agencies, including the FDA, the Federal Trade Commission ("FTC"), the
Consumer Product Safety Commission ("CPSC"), the USDA, the EPA and the United
States Postal Service. The Company's activities are also regulated by various
agencies of the states, localities and foreign countries in which the Company's
products may be manufactured, distributed and sold. The FDA, in particular,
regulates the formulation, manufacture and labeling of weight management
products, dietary supplements, and cosmetics and skin care products, such as
those expected to be manufactured and sold by the Company. FDA regulations
require the Company and its suppliers to meet relevant regulatory good
manufacturing practices for the preparation, packaging and storage of these
products. Good manufacturing practices for dietary supplements have yet to be
promulgated but are expected to be proposed.
 
    A portion of the Company's planned sales will come from products that are
classified as dietary supplements under the Food, Drug and Cosmetic Act
("FDCA"). The labeling requirements for dietary supplements have not been
clearly established. In December 1995, the FDA issued proposed regulations which
govern the labeling of dietary supplements, including how to declare nutritional
information, how to make permissible "statements of nutritional support" and
when additional, defined terminology may be used on dietary supplements. As a
manufacturer of products that are ingested by consumers, the Company is subject
to the risk that one or more of the ingredients in its products may become the
subject of adverse regulatory action.
 
    In foreign markets, prior to commencing operations and prior to making or
permitting sales of its products, the Company may be required to obtain an
approval, license or certification from the country's ministry of health or
comparable agency. Prior to entering a new market in which a formal approval,
license or certificate is required, the Company will be required to work
extensively with local authorities to obtain the requisite approvals. The
approval process generally requires the Company to present each product and
product ingredient to appropriate regulators and, in some instances, arrange for
testing of products by local technicians for ingredient analysis. Such approvals
may be conditioned on reformulation of the Company's products or may be
unavailable with respect to certain products or ingredients.
 
    The FTC and certain states regulate advertising, product claims, and other
consumer matters, including advertising of the Company's products. All
advertising, promotional and solicitation materials used by distributors must be
approved by the Company prior to use. The FTC has in the past several years
instituted enforcement actions against several dietary supplement companies for
false and misleading
 
                                       31
<PAGE>
advertising of certain products. The Company also is subject to the risk of
claims by distributors and customers who may file actions on their own behalf,
as a class or otherwise, and may file complaints with the FTC or state or local
consumer affairs offices. Proceedings resulting from these complaints may result
in significant defense costs, settlement payments or judgments and could have a
material adverse effect on the Company.
 
REGULATION OF PLANT-BASED PROTEINS
 
    TRANSGENIC PLANTS.  The field scale cultivation of new plants constructed
with recombinant DNA techniques requires prior notification to the USDA.
Large-scale growth of transgenic plants requires prior approval by the USDA.
Unless there is some specific concern, approval is usually granted. Issues of
concern include genetic modifications that involve antibiotic resistance,
weediness or invasiveness, and the potential for genetic transfer to other
species.
 
    The manufacture and sale of nutritional and cosmetic products from
transgenic plants are regulated as products derived from naturally occurring
plants. See "Regulation of Nutritional Supplements" in this section.
 
    The use of products such as human collagen in an injectable form requires
approval from the FDA including Phase I, II and III clinical trials. This
approval process takes 7-12 years and for a new drug can cost in excess of $100
million. Because a form of collagen is already in pharmaceutical use, testing
and approval may be less time-consuming and costly than it would otherwise be.
 
LEGAL PROCEEDINGS
 
    The Company is not a party to any material legal proceedings.
 
PERSONNEL
 
   
    The Company currently has eighteen employees, including three administrative
employees, four marketing personnel, four scientists, one engineer and six
laboratory researchers. The Company also has several non-employee consultants.
Seven employees have advanced degrees. None of the Company's employees is
covered by collective bargaining agreements and management considers relations
with its employees to be good.
    
 
FACILITIES
 
    The Company has a five-year lease expiring February 2000 on approximately
11,000 square feet of laboratory and office space located at 1 Deer Park Drive,
Monmouth Junction, New Jersey. This laboratory and office space is anticipated
to be sufficient to meet the Company's needs for at least the next two years.

(1) Member of the Compensation Committee.

STOCK OPTION PLAN
 
    The Company has adopted the Phytotech Stock Option Plan (the "Plan") which
provides for the award of stock options to those employees, directors and
outside consultants of the Company who make substantial contributions to the
Company by their loyalty, industry and invention. The terms and conditions of
each award will be described in a separate agreement between the Company and the
key executive or consultant, as the case may be. The Plan is administered by the
Board of Directors (the "Board") or by a committee to whom the Board delegates
such authority. The Board or, if applicable, the committee appointed by the
Board, has full and final authority in its discretion (i) to interpret the
provisions of the Plan, (ii) to decide all questions of fact arising in the
Plan's application, (iii) to determine the individuals to
 
                                       36
<PAGE>
whom stock options shall be awarded under the Plan, (iv) to determine the
amount, size and terms of each such award, (v) to determine the time when awards
shall be granted, and (vi) to make all other determinations necessary or
advisable for the administration of the Plan.
 
   
    Currently only shares of Non-Voting Common Stock may be issued upon exercise
of options granted under the Plan. The total number of such shares reserved for
issuance subject to options under the Plan may not exceed in the aggregate
555,556 shares. Except as otherwise provided in the Plan, any shares subject to
an option which for any reason expires or is terminated unexercised shall again
be available under the Plan. All shares of Non-Voting Common Stock subject to
currently outstanding stock options will be automatically converted into shares
of Common Stock on a one-for-one basis upon effectiveness of this offering.
Following this offering, the Company intends to amend the Plan to provide for
the issuance of Common Stock on exercise of future options granted under the
Plan. The Company does not plan to grant options or warrants with exercise
prices of less than 85% of the Common Stock's fair market value on the date of
the grant.
    
 
   
    In the event of any change in the outstanding stock of the Company, by
reason of a stock dividend or distribution, recapitalization, merger,
consolidation, split-up, combination, exchange of shares or the like, the Board
may, in its discretion, adjust the number of shares of Common Stock which may be
issued under the Plan. In such event the Board may make any changes it deems
equitable to outstanding stock options. As of March 31, 1998, there were
outstanding options to purchase an aggregate of 253,333 shares of Non-Voting
Common Stock, of which options to purchase 56,444 such shares were exercisable.
    
 
                              CERTAIN TRANSACTIONS
 
   
    The Company has issued certain promissory notes to certain of its directors,
payable on demand, in the aggregate amount of $229,000. Such notes were issued
on May 26, 1997: (i) a $100,000 promissory note issued to Burt Ensley; (ii) a
$100,000 promissory note issued to Philip Whitcome; and (iii) a $25,000
promissory note issued to Abraham Nechemie ((i)-(iii), collectively, the
"Notes"). The Notes provide that the principal and interest on the unpaid
balance accruing from and after the date of issuance (the interest being the
minimum rate on the date of issuance necessary under the Code, to avoid an
imputed rate of interest under the Code) are payable on demand. An additional
note in the principal amount of $4,000 was issued to Burt Ensley on May 26,
1997. The note provides that the principal and the accrued interest in the
amount of 10% on the unpaid balance is payable on demand.
    
 
    Philip Whitcome, Ilya Raskin, Laura Meagher and Abraham Nechemie, directors
of the Company, each have consulting agreements with the Company pursuant to
which such persons perform, from time to time, services to the Company unrelated
to their services as directors. The amount of compensation paid by the Company
under such consulting agreements in 1997 and 1996 was not material.
 
    The Company has paid to Trautman, Kramer and Company, of which Eric Johnson
is an officer, warrants and cash compensation as consideration for its services
as placement agent for the Company in various private placements of the
Company's equity securities and promissory notes. Mr. Johnson received warrants
for services provided to the Company in connection with the Company's two most
recent private placements of promissory notes and warrants.
 
   
    The Company's management believes that the terms of the above transactions
were no less favorable to the Company than would have been obtained from a
nonaffiliated third party. Other than as disclosed above, there are no ongoing
transactions of the Company with affiliates. All prior transactions have been
approved by at least two independent directors.
    
 
   
    The above transactions were, and any future transactions with officers,
directors, or affiliates will be, ratified by a majority of independent outside
members of Phytotech's Board of Directors who do not have an interest in the
transactions, and on terms which are, or will be no less favorable to the
Company than those that can be obtained from unaffiliated third parties. At all
times the Company expects to maintain at least two independent directors on the
board.

                           DESCRIPTION OF SECURITIES
 
GENERAL
 
   
    The following description of the Company's securities is a summary and is
subject in all respects to applicable New Jersey law, provisions of the
Company's Certificate of Incorporation and By-laws, the Warrant Agreement
between the Company and Registrar and Transfer Company, as warrant agent,
pursuant to which the Warrants will be issued, the various agreements pursuant
to which other securities of the Company were issued and the Underwriting
Agreement between the Company and the Underwriter. However, the Company believes
that the material terms of its securities are described in the following
summary.
    
 
   
    Giving effect to the Reverse Split and certain redesignations of capital
stock approved by the Board of Directors to be effective immediately prior to
this offering, the Company is authorized to issue 41,111,111 shares of its
capital stock, without par value, of which 30,000,000 shares are designated as
Voting Common Stock, 1,111,111 are designated as Non-Voting Common Stock,
10,000,000 are designated as Series A Voting Preferred Stock. The Board of
Directors has the authority to divide authorized but unissued shares of capital
stock into classes and series or both and to determine or change the designation
and the number of shares of any class or series, and to determine the number of
shares, the relative rights, preferences and limitations of shares of any class
or series. Upon conversion of the outstanding shares of Non-Voting Common Stock
and Series A Voting Preferred Stock concurrently with this offering, the Company
intends to amend its Certificate of Incorporation to cancel all shares of
Non-Voting Common Stock and Series A Voting Preferred Stock, whereupon the
Company will have designated all 30,000,000 authorized shares as Voting Common
Stock.
    
 
UNITS
 
    Each Unit consists of one share of Common Stock and one Warrant, each
Warrant entitling the holder thereof to purchase one share of Common Stock. The
Units will separate and the Common Stock and Warrants that make up the Warrants
will trade only as separate securities, thirty days after the date of this
Prospectus.
 
COMMON STOCK
 
   
    Holders of Common Stock are entitled to one vote per share on all matters
submitted to a vote of the holders of Common Stock, including the election of
directors. There is no right to cumulate votes for the election of directors.
Subject to the rights of outstanding preferred stock, if any, the holders of
Common Stock are entitled to receive dividends when, as and if declared by the
Board of Directors out of funds legally available for such purpose. Subject to
the rights of outstanding preferred stock, if any, holders of Common Stock are
entitled to receive, on a pro rata basis, all assets of the Company available
for distribution to the stockholders in the event of the liquidation,
dissolution or winding up of the Company. Holders of Common Stock do not have
any preemptive rights to become subscribers or purchasers of additional shares
of any class of the Company's capital stock. All of the issued Common Stock is,
and on issuance as described herein, the Common Stock issuable as a part of the
Units or on exercise of Warrants will be, fully paid and nonassessable.
    
 
NON-VOTING COMMON STOCK
 
    Upon consummation of this offering, the outstanding shares of Non-Voting
Common Stock will be converted into 232,156 shares of Common Stock.
 
                                       39
<PAGE>
SERIES A VOTING PREFERRED STOCK
 
    Upon the consummation of this offering, the outstanding shares of Series A
Voting Preferred Stock will be converted into 1,414,333 shares of Common Stock.
 
WARRANTS
 
REPRESENTATIVE'S WARRANT
 
    In connection with this offering, the Company has authorized the issuance of
the Representative's Warrant and has reserved 400,000 shares of Common Stock for
issuance upon exercise of such warrant (including the warrants issuable upon
exercise of the Representative's Warrant). The Representative's Warrant will
entitle the holder to acquire up to 200,000 Units at an exercise price of
$      per Unit. The Representative's Warrant will be exercisable at any time
from the first anniversary of the date of this Prospectus until the fifth
anniversary of the date of this Prospectus.
 
UNIT WARRANTS
 
    Each Warrant will entitle the holder to purchase one share of Common Stock
at a price of $      per share. The Warrants will, subject to certain
conditions, be exercisable at any time after the Separation Date and until the
fifth anniversary of the date of this Prospectus, unless earlier redeemed. The
Warrants are redeemable by the Company, at $.25 per Warrant, upon thirty days
written notice, if the closing bid price (as defined in the warrant agreement
(the "Warrant Agreement") between the Company and Registrar and Transfer
Company, as Warrant Agent (the "Warrant Agent") described below) per share of
Common Stock for the twenty consecutive trading days immediately preceding the
date notice of redemption is given equals or exceeds $      . If the Company
gives notice of its intention to redeem, a holder would be forced either to
exercise his or her Warrant before the date specified in the redemption notice
or accept the redemption price.
 
    The Warrants will be issued in registered form under the Warrant Agreement.
The shares of Common Stock underlying the Warrants, when issued upon exercise of
a Warrant will be fully paid and nonassessable, and the Company will pay any
transfer tax incurred as a result of the issuance of Common Stock to the holder
upon its exercise.
 
    The Warrants and the Representative's Warrant contain provisions that
protect the holders against dilution by adjustment of the exercise price. Such
adjustments will occur in the event, among others, that the Company makes
certain distributions to holders of its Common Stock. The Company is not
required to issue fractional shares upon the exercise of a Warrant or the
Representative's Warrant. The holder of a Warrant or the Representative's
Warrant will not possess any rights as a shareholder of the Company until such
holder exercises the Warrant or the Representative's Warrant.
 
    A Warrant may be exercised upon surrender of the Warrant certificate
("Warrant Certificate") on or before the expiration date of the Warrant at the
offices of the Warrant Agent, with the form of "Election To Purchase" on the
reverse side of the Warrant Certificate completed and executed as indicated,
accompanied by payment of the exercise price (by certified or bank check payable
to the order of the Company) for the number of shares with respect to which the
Warrant is being exercised.
 
    For a holder to exercise the Warrants, there must be a current registration
statement in effect with the Commission and qualification in effect under
applicable state securities laws (or applicable exemptions from state
qualifications requirements) with respect to the issuance of shares or other
securities underlying the Warrants. The Company has agreed to use all
commercially reasonable efforts to cause a registration statement with respect
to such securities under the Securities Act to be filed and to become and remain
effective in anticipation of and prior to the exercise of the Warrants and to
take such other actions under the laws of various states may be required to
cause the sale of Common Stock (or other securities) upon exercise of Warrants
to be lawful. If a current registration statement is not in effect at the time a
Warrant is
 
                                       40
<PAGE>
exercised, the Company may at its option redeem the Warrant by paying to the
holder cash equal to the difference between the market price of the Common Stock
on the exercise date and the exercise price of the Warrant. The Company will not
be required to honor the exercise of Warrants if, in the opinion of the
Company's Board of Directors upon advice of counsel, the sale of securities upon
exercise would be unlawful.
 
    The foregoing discussion of certain terms and provisions of the Warrants and
the Representative's Warrant is qualified in its entirety by reference to the
detailed provisions of the Warrant Agreement and the Representative's Warrant
certificate (the "Representative's Warrant Certificate"), the form of each of
which has been filed as an exhibit to the Registration Statement of which this
Prospectus is a part.
 
    For the life of the Warrants and the Representative's Warrant, the holders
thereof have 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 Warrants. The Warrant holders may be
expected to exercise their Warrants at a time when the Company would, in all
likelihood, be able to obtain any needed capital by an offering of Common Stock
on terms more favorable than those provided for by the Warrants. Further, the
terms on which the Company could obtain additional capital during the life of
the Warrants may be adversely affected.
 
OTHER WARRANTS
 
    Warrants to purchase a total of 671,091 shares of Common Stock with exercise
prices ranging from $3.60 to approximately $9.00 per share (assuming an offering
price of $6.00 per Unit) are issued or issuable. All of said warrants are
currently exercisable, with the latest expiration date being March 2003.
 
   
    All of the warrants and the Common Stock issuable upon exercise thereof are
restricted securities under the Securities Act and as such are subject to
restrictions on transfer, except for 78,768 shares of Common Stock issuable upon
exercise of warrants which are being registered concurrently with this offering.
    
 
    The holders of the warrants have demand and piggyback registration rights,
subject to certain conditions, whereupon the exercise of said registration
rights the Company is obligated to register the shares of Common Stock
acquirable upon the exercise of the warrants.
 
    The warrants have antidilution provisions which provide for appropriate
adjustment to the exercise price and the number of shares of Common Stock
acquirable upon exercise in the event of stock splits, reverse stock rights,
stock dividends, reclassifications of the Company's securities, mergers or
consolidations or other similar events. Certain of the warrants also contain
price adjustment provisions in the event the Company issues Common Stock for a
consideration per share less than the exercise price in effect immediately prior
to such issuance.
 
PROMISSORY NOTES
 
   
    The Company has outstanding $1,225,000 principal amount of promissory notes
issued September 15, 1997 bearing simple interest at a rate of 10%. In addition,
the Company has outstanding $641,800 and $320,000 principal amount of promissory
notes issued February 27, 1998 and March 16, 1998, respectively, bearing simple
interest at a rate of 12%. In the absence of an initial public offering, the
promissory notes are repayable in 24 equal monthly installments beginning June
30, 1998 (subject to six months extension at the election of a majority in the
principal amount of all noteholders). The Company intends to repay all principal
and interest under the promissory notes with a portion of the net proceeds from
this offering. In addition, the Company has issued certain promissory notes to
certain of its directors, payable on demand in the aggregate amount of $229,000.
Repayment of all of the foregoing notes are secured equally and ratably by a
security interest in the assets of the Company.

REGISTRATION RIGHTS
 
   
    Registration rights agreements have been entered into with holders of
warrants and Preferred Stock of the Company. In general, the warrants have
piggyback registration rights, subject to the orderly distribution of the
Company's securities. In addition, both the warrants and the Preferred Stock
have single-demand registration rights, which are limited during the period one
hundred and eighty (180) days following the effective date of the registration
statement. There are a small number of warrants with double-demand registration
rights. The terms of the agreements provide that in connection with a public
offering of the Company's securities, the parties to the agreements will not
sell their shares of the Company for and during the period beginning on the date
that the Company executes an underwriting agreement with respect to such
offering and continuing to and including 180 days after the date of the
prospectus included in the registration statement under the Securities Act for
such offering, except for approximately 250,000 shares subject to outstanding
warrants which do not have such restrictions of which approximately 140,000 are
subject to lock-up agreements.
    
 
    The existence and exercise of such registration rights may hinder efforts by
the Company to arrange future financing for the Company and may have an adverse
effect on the market price of the Common Stock.
 
TRANSFER AGENT AND REGISTRAR
 
    The transfer agent and registrar for the Company's Common Stock is Registrar
and Transfer Company. Its address is 10 Commerce Drive, Cranford, New Jersey
07016-3572, and its telephone number is (800) 456-0596.

</TABLE>
    
 
   
    The Underwriting Agreement provides that the Underwriters are obligated to
purchase all of the Firm Units if any Units are purchased. The Company has been
advised that the Underwriters propose to offer the Units to the public initially
at the offering price shown on the cover page of this Prospectus and to selected
dealers, including Underwriters, at that price less a concession to be
determined by the Representative. After the initial public offering of the
Units, the public offering price and other offering terms may be changed. The
Underwriters do not expect to sell the Units on a discretionary basis.
    
 
   
    The Company has granted an overallotment option, exercisable by the
Underwriters during the 45-day period after the date of this Prospectus, to
purchase up to 300,000 additional Units (the "Option Units") on the same terms
as are applicable to the Firm Units. The Underwriters may exercise this option
only to cover overallotments in the sale of the Units.
    
 
   
    The Underwriters will purchase the Units (including the Units subject to the
Underwriters' overallotment option) at a discount equal to    % of the initial
public offering price. The Representative will also receive a non-accountable
expense allowance equal to     % of the aggregate initial public offering price
of the Units sold in this offering of which $35,000 has already been paid.
    
 
   
    The Company has agreed to issue the Representative's Warrants to the
Representative. The Representative's Warrants will allow the Representative to
purchase up to 200,000 Units. The Representative's Warrants are exercisable for
a period of four years beginning one year from the date of this Prospectus, at a
price of $    per Unit (120% of the initial public offering price of the Units)
and are restricted from sale, transfer, assignment or hypothecation for a period
of one year after the date of this Prospectus except (i) to any of the
Underwriters or to individuals who are either an officer or a partner of an
Underwriter or members of the selling group or (ii) by will or the laws of
descent and distribution. The holders of the Representative's Warrants will
have, in that capacity, no voting, dividend or other shareholder rights. Any
profits realized on the sale of the securities issuable on exercise of the
Representative's Warrants may be deemed to be additional underwriting
compensation.
    
 
    The sale of the shares issuable upon exercise of the Representative's
Warrants could dilute the interests of the other holders of Common Stock, and
the existence of the Representative's Warrants may make the raising of
additional capital by the Company more difficult. At any time at which exercise
of the Representative's Warrants might be expected, it is likely that the
Company could raise additional capital on terms more favorable than the terms of
the Representative's Warrants.
 
    The Underwriters have requested that all officers, directors and
shareholders of the Company, who own five percent or more of the outstanding
shares of Common Stock (on a fully diluted basis), agree not
 
                                       43
<PAGE>
to sell any Common Stock of the Company, pursuant to Rule 144 under the
Securities Act or otherwise, and the Company has agreed not to sell any Common
Stock without the prior written consent of the Representative, for a period of
one year after the date of this Prospectus.
 
    In addition, the Company has agreed to indemnify the Underwriters against
certain liabilities, including liabilities under the Securities Act, and to
contribute in certain events to any liabilities incurred by the Underwriters in
connection with the sale of the Units.
 
    The Representative has advised the Company that, pursuant to Regulation M
under the Securities Act, certain persons participating in the offering may
engage in transactions, including stabilizing bids, syndicate covering
transactions or the imposition of penalty bids, which may have the effect of
stabilizing or maintaining the market price of the Common Stock at a level above
that which might otherwise prevail in the open market. A "stabilizing bid" is a
bid for or the purchase of the Common Stock on behalf of the Underwriters for
the purpose of fixing or maintaining the price of the Common Stock. A "syndicate
covering transaction" is the bid for or the purchase of Common Stock on behalf
of the Underwriters to reduce a short position incurred by the Underwriters in
connection with the offering. A "penalty bid" is an arrangement permitting the
Representative to reclaim the selling concession otherwise accruing to an
Underwriter or syndicate member in connection with the offering if the Common
Stock originally sold by such Underwriter or syndicate member is purchased by
the Representative in a syndicate covering transaction and has therefore not
been effectively placed by such Underwriter or syndicate member. The
Representative has advised the Company that such transactions may be effected on
the Nasdaq Small Cap Market or otherwise and, if commenced, may be discontinued
at any time.
 
    Prior to the offering, there has been no public market for the Company's
securities. The initial public offering price for the Units will be determined
through negotiations between the Company and the Representative and will be
based on, among other things, the Company's financial condition, the prospects
of the Company and its industry in general, the management of the Company and
the market prices of securities of companies engaged in business similar to
those of the Company.
 
                             CERTAIN LEGAL MATTERS
 
    The validity of the Common Stock offered hereby will be passed upon for the
Company by Shanley & Fisher, P.C., Morristown, New Jersey. Stoel Rives LLP,
Portland, Oregon has acted as counsel for the Underwriters with respect to
certain legal matters in connection with this offering.
 
                                    EXPERTS
 
    The financial statements of the Company as of December 31, 1997 and for each
of the years in the two-year period ended December 31, 1997 have been included
herein and in the registration statement in reliance upon the report of KPMG
Peat Marwick LLP, independent certified public accountants, appearing elsewhere
herein, and upon the authority of said firm as experts in accounting and
auditing. The report of KPMG Peat Marwick LLP covering the December 31, 1997
financial statements contains an explanatory paragraph that states that the
Company's recurring losses from operations and insufficient working capital
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.
 
                             ADDITIONAL INFORMATION

                                                           KPMG PEAT MARWICK LLP
    
 
                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholders
Phytotech, Inc.:
 
    We have audited the accompanying balance sheet of Phytotech, Inc. as of
December 31, 1997, and the related statements of operations, stockholders'
equity (deficit), and cash flows for each of the years in the two-year period
ended December 31, 1997. 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 financial position of Phytotech, Inc. as of
December 31, 1997, and the results of its operations and its cash flows for each
of the years in the two year period then ended in conformity with generally
accepted accounting principles.
 
   
    The accompanying financial statements have been prepared assuming that
Phytotech, Inc. will continue as a going concern. As discussed in note 1 to the
financial statements, Phytotech, Inc. has suffered recurring losses from
operations and has insufficient working capital to fund its current operating
requirements. These factors raise substantial doubt about its ability to
continue as a going concern. Management's plans in regard to these matters are
also described in note 1. The financial statements do not include any
adjustments that might result from the outcome of that uncertainty.

                         NOTES TO FINANCIAL STATEMENTS
 
                           DECEMBER 31, 1996 AND 1997
 
           (INFORMATION AS OF MARCH 31, 1998 AND WITH RESPECT TO THE
            THREE MONTHS ENDED MARCH 31, 1997 AND 1998 IS UNAUDITED)
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    ORGANIZATION
 
    Phytotech, Inc. (the "Company") was organized under the laws of the State of
New Jersey on April 15, 1993. Phytotech currently offers waste cleanup services
using plants grown under carefully controlled conditions to absorb and dispose
of unwanted metals, such as lead or uranium, from toxic waste sites. The Company
has also developed and is beginning to market nutritionally important minerals
absorbed into plants and is beginning to develop technology for the production
of high value proteins in plants.
 
    Since inception, the Company has been engaged in organizational activities,
including raising capital and research and development activities, and in
completing certain studies utilizing its technology. There is no assurance that
the Company will be able to expand the market for its products in the future.
The Company has not yet achieved profitable operations, nor has it ever
generated positive cash flows from operations and there is no assurance that
profitable operations, if achieved, could be sustained on a continuing basis.
Further, the Company's future operations are dependent on the success of the
Company's efforts to raise additional capital, such as the initial public
offering of voting common stock and warrants contemplated herein (the
"Offering"), its research and commercialization efforts, and ultimately, the
market acceptance of the Company's products.
 
    The accompanying financial statements have been prepared on a going-concern
basis which contemplates the continuation of operations, realization of assets
and liquidation of liabilities in the ordinary course of business. The Company
incurred net losses of $2,465,727 and $2,955,141 for the years ended December
31, 1996 and 1997, respectively, and $510,920 (unaudited) for the three months
ended March 31, 1998 and has an accumulated deficit of $8,248,977 (unaudited) at
March 31, 1998. The net losses incurred by the Company have consumed working
capital and weakened the Company's financial position. The Company's ability to
continue in business is dependent upon its success in generating sufficient cash
flow from operations or obtaining additional financing. The Company is currently
attempting to complete an equity financing to raise additional capital through
the Offering. The Company's ability to continue as a going concern is dependent
upon the financing efforts being successful. There can be no assurance that
these efforts will be successful. The financial statements do not include any
adjustments relating to the recoverability and classifications of reported asset
amounts or the amounts of liabilities that might result from the outcome of that
uncertainty.
 
    USE OF ESTIMATES
 
    Management of the Company has made certain estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes
in conformity with generally accepted accounting principles. Actual results
could differ from these estimates.
 
    CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents are short-term, highly liquid investments that are
readily convertible to known amounts of cash and are so near their maturity
(three months or less) that they present insignificant

risk of changes in value because of changes in interest rates. Cash equivalents
are recorded at cost, which approximates market, and include certain
money-market funds.
 
    PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost. Depreciation and amortization of
property and equipment is computed using the straight-line method over the
estimated useful lives of the respective assets (ranging from three to ten
years), or the lease term, whichever is less. Maintenance and repairs are
charged to operations as incurred.
 
    The Company reviews long-lived assets for impairment whenever events or
changes in business circumstances occur that indicate that the carrying amount
of the assets may not be recoverable. The Company assesses the recoverability of
long-lived assets held and to be used based on undiscounted cash flows, and
measures the impairment, if any, using discounted cash flows.
 
    DEFERRED FINANCING AND OFFERING COSTS
 
    Debt offering costs are deferred and amortized based on a straight-line
method over the life of the related notes payable. Cost associated with the
Offering of approximately $70,000 (unaudited) have been deferred at March 31,
1998 and have not been amortized. These costs will be reclassified to equity
upon the successful completion of the Offering or expensed if the Offering is
unsuccessful.
 
    REVENUE RECOGNITION
 
    Payments due under research grants and commercial revenue agreements are
recognized as revenue when the related research expenses are incurred and the
Company's specific performance obligations under the terms of the respective
contracts are satisfied. Revenue recognized in the accompanying financial
statements is not subject to repayment. Payments, if any, received in advance of
performance under the agreements are deferred and recognized as revenue when
earned. Future losses, if any, on contracts are recognized in the period when
identified by the Company.
 
    RESEARCH AND DEVELOPMENT COSTS
 
    All research and development costs are expensed as incurred.
 
    INCOME TAXES
 
    The Company accounts for income taxes using the asset and liability method
of accounting. Under the asset and liability method, deferred tax assets and
liabilities are recognized for the estimated future tax consequences
attributable to differences between the financial statement carrying amounts of
existing assets and liabilities and their respective tax bases and the benefits
arising from operating loss and tax credit carryforwards. Deferred tax assets
and liabilities are measured using enacted tax rates and laws that will be in
effect for the years in which those differences are expected to reverse. The
measurement of deferred tax assets is reduced, if necessary, by a valuation
allowance for any tax benefits which are not expected to be realized. The effect
on deferred tax assets and liabilities of a change in tax rates is recognized in
the period that such tax rate changes are enacted.

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    STOCK-BASED COMPENSATION
 
    The Company accounts for its stock option issuances in accordance with the
provisions of Accounting Principles Board (APB) Opinion No. 25, "Accounting for
Stock Issued to Employees," and related interpretations. As such, deferred
compensation is recorded to the extent that the current market value of the
underlying stock exceeds the exercise price on the date both the number of
shares and the price per share are known (measurement date). Such deferred
compensation is amortized over the respective vesting periods of such option
grants. On January 1, 1996, the Company adopted the disclosure requirements of
Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for
Stock-Based Compensation," which permits entities to continue to apply the
provisions of APB Opinion No. 25 for financial statement reporting purposes and
provide pro forma net loss and net loss per share disclosures for employee
(including director) stock option grants as if the fair-value-based method
defined in SFAS No. 123 had been applied. The Company has elected to continue to
apply the provisions of APB Opinion No. 25 for financial statement reporting
purposes and to provide the pro forma disclosures required by SFAS No. 123.
Transactions with non-employees, in which goods or services are the
consideration received for the issuance of equity instruments, are accounted for
under the fair-value based method defined in SFAS No. 123.
 
    CONCENTRATION OF CREDIT RISK
 
    Financial instruments that potentially subject the Company to concentrations
of credit risk consist primarily of its receivables. The Company's grant and
commercial receivables are due from the U.S. Department of Defense and various
academic and private institutions. As of December 31, 1997, the Company believes
it has no significant concentration of credit risk with its receivables.
 
    FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The fair value of the Company's short-term financial instruments
approximates their carrying value due to the short maturity of those
instruments. The fair value of notes payable approximates their carrying value
due to the short period since their issuance.
 
    EQUITY SECURITY TRANSACTIONS
 
    Since inception, the Company's Board of Directors (the "Board") has
established the fair value of common stock, Series A convertible preferred
stock, stock options and warrants based upon facts and circumstances existing at
the dates such equity transactions occurred, including the price at which equity
instruments were sold to independent third parties.
 
    NET LOSS PER SHARE
 
    Net loss per share is computed in accordance with SFAS No. 128, "Earnings
Per Share." Weighted average common shares outstanding includes both the voting
and non-voting shares of common stock. Outstanding convertible preferred stock,
convertible notes payable, stock options and warrants (see notes 5, 6, 7 and 8)
have not been used in computing diluted net loss per share because to do so
would be anti-dilutive. As such the numerator (net loss) and the denominator
(weighted average shares outstanding), used in computing both basic and diluted
net loss per share are equal. During the periods presented herein, the Company
did not make any nominal issuances of equity securities as discussed in
Securities and Exchange Commission (SEC) Staff Accounting Bulletin No. 98.

    PRO FORMA BALANCE SHEET (UNAUDITED)
 
    Upon the effectiveness of the Offering, all of the outstanding shares of
non-voting common stock convert into 232,156 shares of voting common stock and
all outstanding shares of Series A convertible preferred stock convert into
1,414,333 shares of voting common stock (see notes 6 and 12). The unaudited pro
forma presentation of the March 31, 1998 balance sheet has been prepared
assuming the conversion of the Series A convertible preferred stock and the
non-voting common stock into voting common stock as of March 31, 1998, the most
recent balance sheet included in the accompanying financial statements.
 
    UNAUDITED FINANCIAL STATEMENTS
 
    The balance sheet at March 31, 1998, the statements of operations and cash
flows for the three months ended March 31, 1997 and 1998 and the statement of
stockholders' equity (deficit) for the three months ended March 31, 1998 are
unaudited. In the opinion of management of the Company, such unaudited financial
statements include all adjustments (consisting of normal recurring accruals)
necessary for a fair presentation of financial results for these periods. The
results of operations for the three months ended March 31, 1998 are not
necessarily indicative of results to be expected for the entire fiscal year.
 
    REVERSE STOCK SPLIT
 
   
    On           , 1998, the Company effected a 1:4.5 reverse stock split of its
voting and non-voting common stock. All voting and non-voting common shares and
per share amounts in the accompanying financial statements (except as to noted)
have been retroactively adjusted to reflect this reverse stock split. Preferred
stock amounts have not been retroactively adjusted to reflect the reverse stock
split.
    
 
    AUTHORIZED SHARES
 
   
    As a result of the reverse stock split and certain actions approved by the
Board, effective on           , 1998, the Company's authorized capital stock
consists of 30,000,000 shares of voting common stock, 10,000,000 shares of
Series A convertible preferred stock and 1,111,111 non-voting common stock.
Given the interrelated nature of these actions, these authorized shares have
been reflected on the balance sheet.

(4) RELATED PARTIES
 
    During 1997, the Company executed promissory notes with certain directors
and an officer aggregating $229,000 payable on demand. Interest on these notes
is approximately 5%.
 
    During 1997, in connection with both private note offerings (see note 5),
the Company paid fees of approximately $200,000 (approximately $260,000 in total
upon completion of the second private note offering on March 16, 1998) and is
obligated to issue warrants (see note 5) to the placement agent who employs one
of the Company's directors.
 
(5) NOTES PAYABLE AND CONVERTIBLE NOTES PAYABLE
 
    In 1997, the Company through a private offering and issued promissory notes
aggregating $1,225,000 and warrants to purchase 54,444 shares of voting common
stock. The Company received net proceeds after offering costs of $1,017,000. The
notes bear total interest of 10% regardless of the period the principal is
outstanding. The notes are secured by the assets of the Company and are
repayable starting at the earlier of (i) seven days after receipt of proceeds
from an initial public offering or (ii) June 30, 1998 in equal payments over a
24 month period (subject to extension for a period of six months at the option
of the majority in principal amount of all note holders). The warrants are
exercisable at $2.50 (pre-reverse-split) (to be subsequently adjusted upon the
effectiveness of the offering based upon a formula contained in the

warrant agreements) from the date of offering to five years after the offering
date. No value was ascribed to the warrants based on the fair value as
determined by a Black Scholes option pricing model calculation.
 
    In December 1997, the Company began a private offering of convertible
promissory notes and warrants to purchase shares of voting common stock. As of
December 31, 1997, the private offering was ongoing. The Company received gross
proceeds of $308,360 and net proceeds after offering costs of $277,525 in 1997.
The Company completed the private offering on March 16, 1998 for $961,800 of
cumulative gross proceeds and net cumulative proceeds after offering costs of
approximately $850,000.
 
   
    The notes bear total interest of 12% regardless of the period the principal
is outstanding. The notes are secured by the assets of the Company and are
repayable at the earlier of (i) seven days after receipt of proceeds from an
initial public offering or (ii) June 30, 1998 (subject to extension for a period
of six months at the option of the majority in principal amount of all note
holders) in equal payments over a 24 month period. The notes are convertible
into voting common stock at the holders' option upon stated written notice prior
to the time the Company's voting common stock becomes publicly traded. No
beneficial conversion feature existed on the date of issuance of the notes,
however, if the Company's voting common stock becomes publicly traded and a
holder elects conversion (with the appropriate prior written notice), the holder
would receive the greater number of voting common shares computed by dividing
the note principal and interest by either (i) 60% of the market price of the
common stock or (ii) $2.50. Any beneficial conversion feature will be recorded
as additional interest expense at the time the Company's voting common stock
becomes publicly traded.
    
 
    In addition, the Company is obligated to issue 20,578 warrants at December
31, 1997 (64,120 total warrants upon completion of the private offering, which
were issued during the three months ended March 31, 1998) to investors. The
warrants are exercisable at $2.50 (pre-reverse-split) (to be subsequently
adjusted upon the effectiveness of the Offering based upon a formula contained
in the warrant agreements) from the offering date to five years after the
offering date. No value was ascribed to the warrants based on the fair value as
determined by a Black Scholes option pricing model calculation.
 
   
    The Company has agreed to issue 269,658 warrants to purchase voting common
stock to the placement agent as total warrant consideration in connection with
both private offerings. The exercise price of the warrants will be 150% of the
price in an initial public offering of the Company's common stock and will have
a five year term.
    
 
(6) CAPITAL STOCK
 
    In the event of any liquidation, dissolution, or winding up of the Company,
the holders of preferred stock are entitled to receive out of assets of the
Company available for distribution to stockholders, after satisfaction of
indebtedness but before any distribution of assets is made to holders of common
stock, liquidating distributions in the amount of $.80 per share, plus declared
and unpaid dividends, if any.
 
    Subject to the dividend rights of holders of the preferred stock, holders of
common stock are entitled to any dividend declared by the Board out of funds
legally available for such purpose, and, after the payment of the $.80 per share
liquidation preference to holders of preferred stock ($5,091,600 in the
aggregate), holders of common stock are entitled to receive on a pro rata basis
all remaining assets of the

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
(6) CAPITAL STOCK (CONTINUED)
 
Company available for distribution to the stockholders in the event of the
liquidation, dissolution, or winding up of the Company. Holders of common stock
do not have any preemptive right to become subscribers or purchasers of
additional shares of any class of the Company's capital stock.
 
   
    There is no optional conversion of preferred stock into common stock. On the
fifth anniversary of the closing date of the first private placement of
preferred stock which closed in November 1994 (the First Offering), shares of
preferred stock then outstanding will automatically be converted into shares of
common stock at a rate of one (pre-reverse split) share of common stock for each
share of preferred stock, subject to adjustment, (the Conversion Rate).
Outstanding shares of preferred stock will also be automatically converted into
shares of common stock at the Conversion Rate (a) upon the effectiveness of an
underwritten public offering of common stock of the Company pursuant to which
common stock is offered to the public at a price of at least $3.00 per share
(pre-reverse-split), or (b) immediately prior to the effectiveness of a
consolidation or merger of the Company with or into another corporation or any
sale or transfer of all or substantially all of the assets of the Company,
pursuant to which holders of common stock (assuming the conversion of all
outstanding preferred stock into common stock at the Conversion Rate) will
receive cash, securities or property having a value (as determined by the
Company's Board) of at least $3.00 per share of common stock (pre-reverse-split)
(see note 12). The holder of any shares of preferred stock converted into common
stock in connection with such a public offering or other transaction will be
entitled to payment of all declared but unpaid dividends, if any, payable with
respect to such shares up to and including the date of the closing of such
public offering or other transaction.
    
 
    Holders of preferred stock will not be entitled to receive dividends on the
preferred stock unless and until dividends are paid and declared on the common
stock. If dividends are paid on the common stock, holders of preferred stock
shall be entitled to receive dividends on the preferred stock at the same time
and at the rate per share of preferred stock based upon the shares of common
stock to which the holders of preferred stock would be entitled, if they had
converted the preferred stock and been holders of common stock on the record
date for such dividend on the common stock.
 
    Each share of preferred stock will be entitled to one vote and will vote
together with the common stock.
 
    The non-voting common stock is convertible into voting common stock at a 1:1
ratio in the event of a public offering of registered securities.
 
    In 1996, the Company sold, in a confidential private offering, 1,452,000
shares of the Company's Series A convertible preferred stock for an aggregate
price of $1,815,000. Expenses relating to the private offering amounted to
$160,459 in agent fees and legal, accounting and printing costs.
 
    In 1996 and 1997, employees exercised stock options for 3,733 and 578
shares, respectively, of non-voting common stock at exercise prices of $.45 per
share. For the three months ended March 31, 1998, employees exercised stock
options for 1,178 shares of non-voting common stock at an average exercise price
of $.66 per share (unaudited).
 
    In 1996, a shareholder was awarded 1,111 shares of non-voting common stock
for services performed. Compensation expense of $500 was recorded which
represented the deemed fair value of the stock as determined by the Board. In
1997, an employee and consultant were awarded 6,667 shares of non-voting common
stock for services performed. Compensation expense totaling $5,000 was recorded
which represented the deemed fair value of the stock as determined by the Board.

(7) STOCK OPTIONS
 
    On July 15, 1994, the Board adopted the Phytotech, Inc. Stock Option Plan
(the "Plan") which provides for the award of stock options to certain employees,
directors and outside consultants of the Company. The terms and conditions of
each award will be described in a separate agreement between the Company and the
individual recipient. The Plan is to be administered by the Board or by a
committee to whom they delegate such authority.
 
    The shares of non-voting common stock that may be issued under the Plan
shall not exceed in the aggregate a maximum of 222,222 shares (on March 3, 1998,
the Board approved, subject to shareholder approval (see note 12) an increase in
the maximum number of shares to 555,556). Such shares shall be issued from
authorized and unissued shares or treasury stock. Except as otherwise provided
in the Plan, any shares subject to an option, which for any reason expires or is
terminated unexercised, shall again be available under the Plan. Unless
terminated earlier, the Plan shall terminate on July 15, 2004. No stock options
or rights under the Plan shall be granted thereafter. The Board, without
approval of the Company's stockholders, may at any time before that date
terminate the Plan.
 
    The Company had outstanding 37,333 stock options at an exercise price of
$.45 as of December 31, 1995. In 1996, 26,067 options were granted at a $.45 per
share exercise price and 3,733 options were exercised at a $.45 per share
exercise price. In 1997, 174,333 options were granted at an exercise price of
$.68 per share, 578 options were exercised at $.45 per share and 13,578 options
were canceled. The outstanding options at December 31, 1997 were 219,844 with a
weighted average exercise price of $.63. Shares available for grant at December
31, 1997 were 2,378. The options vest at various times over the next five-year
period and expire 10 years from date of grant. At December 31, 1997, 31,422
options were exercisable with a $.68 exercise price and 22,356 options were
exercisable with a $.45 exercise price.
 
   
    On October 1, 1997, the Company granted 142,222 options primarily to certain
officers and Board members. These options vest ratably on an annual basis over
five years and have an exercise price of $.68 per option. The difference between
the deemed fair value for financial reporting purposes as determined by the
Board based on facts and circumstances which existed on that date, including
technology developments, agreements/transactions entered into by the Company,
the Company's financial condition and the price at which equity securities were
previously sold to independent third parties, and the $.68 exercise price at the
grant date has been recorded as deferred compensation ($385,000) and is being
amortized over the aforementioned vesting period. For other option grants in
1996 and 1997, the exercise price approximated the deemed fair value of the
common stock at the date of grant as determined by the Board. In accordance with
APB Opinion No. 25, no compensation cost has been recognized for these employee
stock options in the financial statements. Had the Company determined
compensation cost based on the fair value at the grant date for its stock
options under SFAS No. 123, the Company's net loss would have been increased to
the pro forma amounts as follows:

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
(7) STOCK OPTIONS (CONTINUED)
    The per-share, weighted-average fair value of stock options granted during
1996 and 1997 was approximately $.18 and $.32, respectively, on the date of
grant using the Black Scholes option-pricing model with the following
weighted-average assumptions: no expected dividend yield, risk free interest
rate of approximately 6.5%, expected life of ten years and no volatility as the
stock is not publicly traded.
 
   
    On March 3, 1998, the Board granted, subject to shareholder approval to
increase the number of shares available under the Plan, 34,667 stock options to
certain employees. These options have an exercise price of $.68 per share and
vest over five years. The difference between the deemed fair value for financial
reporting purposes as determined by the Board based on facts and circumstances
which existed on that date, including technology developments,
agreements/transactions entered into by the Company, the Company's financial
condition and the price at which equity securities were previously sold to
independent third parties, and the $.68 exercise price at grant date has been
recorded as deferred compensation ($132,000) and is being amortized over the
aforementioned vesting period.
    
 
(8) WARRANTS
 
    As of December 31, 1997, the Company has outstanding warrants to purchase
shares of voting common stock totaling 326,202 (all of which are exercisable) at
prices ranging from $.80 to $2.50 (pre-reverse split, some of which will
subsequently adjust upon effectiveness of the Offering based upon a formula
contained in the warrant agreements). These warrants were issued in connection
with the Series A convertible preferred stock sales (see note 6) and the
issuance of notes payable (see note 5). All warrants expire within the next five
years. As of March 31, 1998, outstanding warrants to purchase shares of voting
common stock totaled 401,433 (all of which are exercisable) with exercise prices
ranging from $.80 to $2.50 (unaudited) (subject to adjustments as above).
 
(9) RESEARCH AND LICENSE AGREEMENTS
 
    During 1994, the Company entered into an initial three-year research
agreement with an academic institution (the "Institution") to perform certain
studies and field trials for the phytotreatment of heavy metals. Under the
research agreement the Company was to reimburse the Institution for all direct
and indirect costs, a total amount not to exceed approximately $1,100,000 over a
three-year period ending in 1997. In 1997, the agreement was extended for an
additional five years under which the Company has agreed to reimburse the
Institution for certain costs up to but not exceeding $500,000 in the aggregate.
The research agreement may be terminated by either party without any further
financial obligation by giving written notice to the other party of at least 90
days. Each of the studies has specific terms and conditions covering the
ownership of intellectual property conceived or discovered during the
performance of the work. Through December 31, 1997, $1,100,000 of research and
development expense under the initial agreement was incurred ($290,000 in 1996,
$250,000 in 1997 and $100,000 (unaudited) in the three months ended March 31,
1997). Under the 1997 extension, $49,000 of research and development expense was
incurred in 1997 and $21,000 (unaudited) was incurred for the three months ended
March 31, 1998. The Company is remitting payments to the Institution at certain
agreed-upon dates during the term of the agreement; $86,000 is scheduled to be
remitted in 1998.
 
    In 1997, the Company entered into a license agreement with the same
Institution for certain technology previously discovered as well as newly
discovered technology under the extended research agreement. The license period
is through the individual patent expiration date. In exchange for the license,
the Company granted the Institution 100,000 shares of Series A convertible
preferred stock. The deemed

fair value of this stock as determined by the Board was $125,000 which has been
expensed in the accompanying statement of operations. The Company is also
obligated to pay royalties on future net sales.
 
(10) INCOME TAXES
 
    The tax effects of temporary differences that give rise to significant
portions of the Company's deferred tax assets as of December 31, 1997 are as
follows:
 
<TABLE>
<S>                                               <C>

                                                  ----------
</TABLE>
 
    The valuation allowance previously noted offsets the deferred tax assets to
recognize the uncertainty of realizing such tax benefits. The net change in the
valuation allowance for the year ended December 31, 1997 was an increase of
$1,176,000, primarily related to additional net operating losses incurred by the
Company which are not currently deductible.
 
    At December 31, 1997, the Company has available net operating loss
carryforwards (NOL) of approximately $6,875,000 for Federal and state income tax
reporting purposes which are available to offset future Federal and state
taxable income, if any. These carryforwards expire beginning in 2000 for state
tax purposes and 2008 for Federal tax purposes. The Company also has research
and development credit carryforwards of approximately $119,000 for Federal
income tax reporting purposes which are available to reduce Federal income
taxes, if any, through 2008. The Company made no payments of Federal or state
income taxes, other than minimum state tax payments, since inception.
 
    The Tax Reform Act of 1986 (the Act) provides for a limitation on the annual
use of NOL and research and development tax credit carryforwards (following
certain ownership changes, as defined by the Act) which could significantly
limit the Company's ability to utilize these carryforwards. The Company has
experienced various ownership changes, as defined by the Act, as a result of
past financings and may experience others in connection with future financing.
Accordingly, the Company's ability to utilize the aforementioned carryforwards
may be limited. Additionally, because U.S. tax laws limit the time during which
these carryforwards may be applied against future taxes, the Company may not be
able to take full advantage of these attributes for Federal income tax purposes.
 
(11) COMMITMENTS
 
    In December 1997, the Company entered into an agreement with a consultant
whereby he was granted 11,111 warrants during the three months ended March 31,
1998, which were issued during the three months ended March 31, 1998, to
purchase voting common stock at $2.00 (pre-reverse split) (subsequently adjusted
upon the effectiveness of Offering based upon a formula in the warrant
agreement). The warrants have a five year term. No value was ascribed to the
warrants based on the fair value as determined by a Black Scholes option pricing
model calculation. An additional warrant to purchase 44,444 voting common shares
will be issued if certain performance criteria is met. The Company will also pay
$2,000 per month for 5 months in connection with this agreement.

    On May 17, 1996, the Company's president and chief executive officer
executed a three year employment agreement at a base salary of $120,000 per
year. A performance bonus of $15,000 was paid to him in 1996 (none in 1997). In
addition, under the agreement he received stock options for 10,000 shares of
non-voting common stock at an exercise price of $.45 per share vesting over a
three year period.
 
    The Company has entered into various other consulting agreements with
individuals to perform consulting services on behalf of the Company. Forms of
compensation vary between the payment of cash and granting of stock of the
Company, as approved by the Board. All consulting agreements contain provisions
that protect confidential information, proprietary data and intellectual
property of the Company. In the event that the consultant is deemed the sole
inventor of any intellectual property conceived during the terms of the
consulting agreement which is assigned to the Company, and the Company, at its
sole discretion and expense, obtains issued patents for the intellectual
property, the consultant shall receive a royalty from the Company during the
life of the patent equal to 5% of the portion of the gross revenues earned
attributable to the patented product, process or method invented by the
consultant, or a royalty of 2% in the event the consultant is deemed a
co-inventor of the patented technology (or a percentage mutually agreed upon by
the parties as a royalty if there are more than two co-inventors). Each
consultant has agreed that he will not be entitled to any additional
compensation by law or otherwise beyond that to which he is entitled under the
consulting agreement for any intellectual property.
 
    In 1997, the Company entered into a cooperative research agreement whereby
the Company is obligated to perform certain services valued in the aggregate at
$150,000 in 1998 and 1999.
 
    The Company rents certain equipment and leases, laboratory and office space
under various noncancelable operating lease agreements. Future minimum lease
payments under noncancelable leases as of December 31, 1997 are as follows:

(12) SUBSEQUENT EVENTS (UNAUDITED)
 
    INITIAL PUBLIC OFFERING
 
    On April 21, 1998, the Board authorized the filing of a registration
statement for the Offering with the SEC for the sale of up to 2,300,000 units
(including 300,000 for the underwriter's overallotment option) consisting of one
share of common stock and a warrant to purchase one share of common stock. All
shares of Series A convertible preferred stock and the non-voting common stock,
assuming effectiveness of the Offering, outstanding as of the closing date of
the Offering will convert into shares of voting common stock on a 1:.22 basis
and 1:1 basis, respectively.
 
    AUTOMATIC CONVERSION
 
    In April 1998, the Board and stockholders approved the removal of a
provision of the Series A convertible preferred stock requiring that the
offering price be above $3.00 (pre-reverse split) (subject to adjustment for
stock splits, combinations and similar events) to automatically convert into
voting common stock in an underwritten public offering.

ITEM 24. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
   
    Phytotech is organized under the laws of the State of New Jersey. The New
Jersey Business Corporation Act, as amended (the "Act"), provides that a New
Jersey corporation has the power generally to indemnify its directors, officers,
employees and other agents against expenses and liabilities in connection with
any proceeding involving such person by reason of his being a corporate agent,
other than a proceeding by or in the right of the corporation, if such person
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation and, with respect to any
criminal proceeding, such person had no reasonable cause to believe his conduct
was unlawful. In the case of an action brought by or in the right of the
corporation, indemnification of directors, officers, employees and other agents
against expenses permitted if such person acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation; however, no indemnification is permitted in respect to any claim,
issue or matter as to which such person shall have been adjudged to be liable to
the corporation, unless and only to the extent that the New Jersey Superior
Court, or the court in which such proceeding was brought, shall determine upon
application that despite the adjudication of liability, but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to such
indemnification. Expenses incurred by a director, officer, employee or other
agent in connection with a proceeding as authorized by the board of directors.
The power to indemnify and advance expenses under the Act does not exclude other
rights to which a director, officer, employee or other agent of the corporation
may be entitled to under the certificate of incorporation, by-laws, agreement,
vote of shareholders, or otherwise provided that no indemnification is permitted
to be made to or on behalf of such person if a judgment or other final
adjudication adverse to such person establishes that his acts or omissions were
in breach of his duty of loyalty to the corporation, were not in good faith or
involved a violation of the law, or resulted in the receipt by such person of an
improper personal benefit.
    
 
    Under the Act, a New Jersey corporation has the power to purchase and
maintain insurance on behalf of any director, officer, employee or other agent
against any expenses incurred in any proceeding and any liabilities asserted
against him by reason of his being or having been a corporate agent, whether or
not the corporation has the power to indemnify him against such expenses and
liabilities under the Act. All powers granted to a New Jersey corporation
discussed above may be exercised by such corporation notwithstanding the absence
of any provision in its certificate of incorporation or by-laws authorizing the
exercise of such powers. However, a New Jersey corporation may, with certain
limitations, provide in its certificate of incorporation that a director or
officer shall not be personally liable, or shall be liable only to the extent
therein provided, to the corporation or its shareholders for damages for breach
of any duty owed to the corporation or its shareholders.
 
   
    The Company's Amended and Restated Certificate of Incorporation (the
"Certificate of Incorporation") provides in Article SIXTH, a director or officer
of Phytotech shall not be personally liable to the Company or its shareholders
for damages for breach of duty as director or officer, except to the extent and
for the duration of any period of time such personal liability may not be
eliminated or limited under the Act as the same exists, or may hereafter be
amended.
    
 
    The Certificate of Incorporation further provides in Article SEVENTH all
corporate officers, directors, employees and agents shall be indemnified to the
full extent permitted by law. Such indemnification may be funded through
insurance or otherwise as authorized by the Board of Directors.
 
   
    Section 7 of the Company's Amended and Restated By-Laws provides that the
Company shall indemnify to the full extent permitted by law any person made, or
threatened to be made, a party to an action, suit or proceeding (whether civil,
criminal, administrative or investigative) by reason of the fact that

    distribution not previously disclosed in the registration statement or any
    material change to such information in the registration statement.
 
    (2) To provide to the underwriters at the closing specified in the
underwriting agreement certificates in such denominations and registered in such
names as required by the underwriters to permit prompt delivery to each
purchaser.
 
    (3) For determining liability under the Securities Act, to treat each
post-effective amendment as a new registration statement of the securities
offered, and the offering of the securities at that time to be the initial bona
fide offering.
 
    (4) To remove from the registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.
 
    (5) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers or controlling persons of the
registrant, pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that, in the opinion of the Securities and Exchange Commission,
such indemnification is against public policy as expressed in the Securities
Act, and is therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer, or controlling person in
connection with the securities being registered hereunder, the registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
   
    (6) For determining any liability under the Securities Act, to treat the
information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 403A and contained in a form of
prospectus filed by the issuer under Rule 424(b)(1) or (4) or 497(h) under the
Securities Act as part of this registration statement as of the time the
Commission declared it effective.
    
 
    (7) For determining any liability under the Securities Act, to treat each
post-effective amendment that contains a form of prospectus as a new
registration statement for the securities offered in the registration statement,
and that offering of the securities at that time as the initial bona fide
offering of those securities.

NO.                             [PHYTOTECH LOGO]                        WARRANTS


              INCORPORATED UNDER THE LAWS OF THE STATE OF NEW JERSEY

THIS CERTIFIES THAT, FOR VALUE RECEIVED                        CUSIP 718954 11 8

     or registered assigns, is the registered holder of the number of Warrants 
("Warrants") set forth above. Each Warrant entitles the holder thereof to 
purchase from Phytotech, Inc. a corporation incorporated under the laws of the 
State of New Jersey ("Company"), subject to the terms and conditions set forth 
hereinafter and in the Warrant Agreement hereinafter more fully described (the 
"Warrant Agreement") referred to, one fully paid and non-assessable share of 
Common Stock, no par value, of the Company ("Common Stock") upon presentation 
and surrender of this Warrant Certificate with the instructions for the 
registration and delivery of Common Stock filed in, at any time on or after 
__________, 1998 and at or before the close of business on __________, 2003 
or, if such Warrant is redeemed as provided in the Warrant Agreement, at any 
time prior to the effective time of such redemption, at the stock transfer 
office in Cranford, New Jersey, of Registrar and Transfer Company, Warrant 
Agent of the Company ("Warrant Agent") or of its successor warrant agent or, 
if there be no successor warrant agent, at the corporate offices of the 
Company, and upon payment of the Exercise Price (as defined in the Warrant 
Agreement) and any applicable taxes paid either in cash, or by certified or 
official bank check, payable in lawful money of the United States of America 
to the order of the Company. Each Warrant initially entitles the holder to 
purchase one share of Common Stock for $_____. The number and kind of 
securities or other property for which the Warrants are exercisable are 
subject to further adjustment in certain events, such as mergers, splits, 
stock dividends, recapitalizations and the like, to prevent dilution. The 
Company may redeem any or all outstanding and unexercised Warrants at any time 
if the Daily Price has exceeded $_____ for twenty (20) consecutive trading 
days immediately preceding the date of notice of such redemption, upon thirty 
(30) days notice, at a price equal to $0.25 per Warrant. For the purpose of 
the foregoing sentence, the term "Daily Price" shall mean, for any relevant 
day, the closing bid price on that day as reported by the principal exchange 
or quotation system on which prices for the Common Stock are reported. All 
Warrants not theretofore exercised or redeemed will expire on __________, 2003.

     This Warrant Certificate is subject to all of the terms, provisions and 
conditions of the Warrant Agreement, dated as of __________, 1998 ("Warrant 
Agreement"), between the Company and the Warrant Agent, to all of which terms, 
provisions and conditions the registered holder of this Warrant Certificate 
consents by acceptance hereof. The Warrant Agreement is incorporated herein by 
reference and made a part hereof and reference is made to the Warrant 
Agreement for a full description of the rights, limitation of rights, 
obligations, duties and immunities of the Warrant Agent, the Company and the 
holders of the Warrant Certificates. Copies of the Warrant Agreement are 
available for inspection at the stock transfer office of the Warrant Agent or 
may be obtained upon written request addressed to the Company at 1 Deer Park 
Drive, Suite l, Monmouth Junction, New Jersey 06852, Attention: Controller.

     The Company shall not be required upon the exercise of the Warrants 
evidenced by this Warrant Certificate to issue fractions of Warrants, Common 
Stock or other securities, but shall make adjustment therefor in cash on the 
basis of the current market value of any fractional interest as provided in the 
Warrant Agreement.

     In certain cases, the sale of securities by the Company upon exercise of 
Warrants would violate the securities laws of the United States, certain 
states thereof or other jurisdictions. The Company has agreed to use its best 
efforts to cause a registration statement to continue to be effective during 
the term of the Warrants with respect to such sales under the Securities Act 
of 1933, and to take such action under the laws of various states as may be 
required to cause the sale of securities upon exercise to be lawful. However, 
the Company will not be required to honor the exercise of Warrants if, in the 
opinion of the Board of Directors, upon advice of counsel, the sale of 
securities upon such exercise would be unlawful. In certain cases, the Company 
may, but is not required to, purchase Warrants submitted for exercise for a 
cash price equal to the difference between the market price of the securities 
obtainable upon such exercise and the exercise price of such Warrants.

     This Warrant Certificate, with or without other Certificates, upon 
surrender to the Warrant Agent, any successor warrant agent or, in the absence 
of any successor warrant agent, at the corporate offices of the Company, may 
be exchanged for another Warrant Certificate or Certificates evidencing in the 
aggregate the same number of Warrants as the Warrant Certificate or 
Certificates so surrendered. If the Warrants evidenced by this Warrant 
Certificate shall be exercised in part, the holder hereof shall be entitled to 
receive upon surrender hereof another Warrant Certificate or Certificates 
evidencing the number of Warrants not so exercised.

     No holder of this Warrant Certificate, as such, shall be entitled to 
vote, receive dividends or be deemed the holder of Common Stock or any other 
securities of the Company which may at any time be issuable on the exerciser 
hereof for any purpose whatsoever, nor shall anything contained in the Warrant

described in Exhibit A substantially in accordance with the terms and conditions
of this AGREEMENT.

3.   PRINCIPAL INVESTIGATOR
     RUTGERS will conduct the RESEARCH PROJECT under the direction and
supervision of Dr. Ilya Raskin, the PRINCIPAL INVESTIGATOR (PI).  If for any
reason the PI is unable to continue the research project, and a SPONSOR
acceptable substitute is not available, SPONSOR may terminate this AGREEMENT
according to the terms of Article 18.


<PAGE>


4.   PERIOD OF PERFORMANCE
     The period during which the RESEARCH PROJECT is to be performed shall run
from September 1, 1993 to June 30, 1994, and may be extended, renewed, or
amended by the mutual written agreement of both parties.


5.   REIMBURSEMENT OF COSTS

this AGREEMENT.

8.   PROPRIETARY DATA
     During the term of the RESEARCH PROJECT, it may be necessary or desirable
for SPONSOR to divulge to RUTGERS certain information which SPONSOR considers to
be proprietary.  Such Proprietary Information will be plainly marked in writing
before delivery, where possible.  RUTGERS agrees to make a good faith effort to
hold such information in confidence during the term of this AGREEMENT and for
three years beyond the termination of this AGREEMENT.  The standards observed by
RUTGERS in its good faith effort are to be the same as would apply to the
security of its own confidential records.  RUTGERS reserves the right to refuse
to accept Proprietary Information which it does not consider essential to the
completion of the RESEARCH PROJECT.  Furthermore, RUTGERS is not obliged to
treat as proprietary any information which is (i) public information, (ii)
already known to RUTGERS or its personnel, in their capacity as RUTGERS
employees (iii) independently developed at a later time by RUTGERS personnel
without knowledge of SPONSOR's Proprietary Information, (iv) provided to RUTGERS
by a third party without breaching any obligation to SPONSOR, or (v) required to
be disclosed by court order.  RUTGERS further agrees to destroy or return any
such Proprietary Information and any and all copies thereof to SPONSOR upon
request.

9.   PUBLICATIONS
     Publication of research results is one of the primary missions of RUTGERS
and SPONSOR agrees that researchers engaged in the RESEARCH PROJECT shall be
permitted to present at symposia, national or regional professional meetings,
and to publish in journals, theses or dissertations, or otherwise of their own
choosing, methods and results of the project.  However, SPONSOR will be
furnished copies of any proposed publication or presentation for review and
comment at least thirty (30) days in advance of the submission of such proposed
publication or presentation to a journal editor, or other third party.  During
this 30 day period, SPONSOR may 


<PAGE>



request: a) that RUTGERS delay publication to allow time for SPONSOR to file a
United States patent applications on RUTGERS' behalf, such period not to exceed
twelve (12) months; and b) that RUTGERS delete from the proposed publication
Proprietary Information obtained from SPONSOR by RUTGERS personnel during the
course of the RESEARCH PROJECT.  The submission and cataloging of any thesis or
dissertation prepared by a graduate student in fulfillment of an academic degree
requirement shall be delayed only in accord with procedures approved by RUTGERS.

10.  INTELLECTUAL PROPERTY
     a.   All rights and title to Intellectual Property conceived or discovered
          in the performance of this RESEARCH PROJECT shall belong to RUTGERS
          and shall be subject to the terms and conditions of this AGREEMENT.

     b.   RUTGERS will promptly notify SPONSOR once it has identified any
          potentially valuable Intellectual Property conceived and/or made
          during the term of this AGREEMENT. If SPONSOR directs that a patent
          application or application for other Intellectual Property Protection
          be filed, RUTGERS shall promptly prepare, file, and prosecute such
          U.S. and foreign applications in RUTGERS' name using a firm or
          attorney that is chosen by RUTGERS, or at SPONSOR's option, an
          attorney selected by SPONSOR subject to RUTGERS approval.  SPONSOR
          shall bear all costs incurred in connection with such preparation,
          filing, prosecution, and maintenance of U.S. and foreign applications
          directed to such RUTGERS Intellectual Property.  SPONSOR shall be
          given the opportunity to review and provide input to such applications
          to assure that SPONSOR's interests are covered.  RUTGERS shall keep
          SPONSOR advised as to all developments with respect to such
          applications and shall promptly supply SPONSOR copies of all papers
          received and filed in connection with the prosecution.
          
     c.   If SPONSOR does not request RUTGERS to file for Protection of
          Intellectual Property in a particular country, or decides to
          discontinue the financial support of the prosecution or maintenance of
          the Protection in that country, RUTGERS may pursue whatever course it
          deems necessary to protect its Intellectual Property, and RUTGERS
          shall have no further obligation to SPONSOR to option or to license
          with regard to that country.
          
11.  GRANT OF RIGHTS
     SPONSOR will promptly decide whether to pay for all costs of filing
applications for Protection.  If SPONSOR agrees to pay preparation fees and
filing costs, RUTGERS hereby grants SPONSOR an option to a license on
Intellectual Property resulting from the performance of research under this
AGREEMENT.  This option will expire six (6) months from disclosure of the
Intellectual Property, evidenced by a dated receipt.  Upon exercise of this
option, RUTGERS shall grant to SPONSOR, under a separate agreement, a license
which will include provisions for:

     a.   An exclusive or nonexclusive worldwide license, with a right to
          sublicense, for the duration of the protection afforded by U.S. and
          foreign law, in the field(s) of use for which the SPONSOR can
          demonstrate commercial intent.
          
     b.   A reasonable royalty paid to RUTGERS on the gross sales of any
          product, apparatus, or process commercially introduced as a result of
          the research work performed, including minimum royalty and due
          diligence clause(s).
          
     c.   Agreement by RUTGERS and SPONSOR to negotiate in good faith the terms
          and conditions of a license agreement which are satisfactory to both
          parties.  However, in the event of disagreement, the disputed matters
          will be submitted for arbitration under the rules and procedures of
          the American Arbitration Association.
          
          
<PAGE>


          
12.  INDEPENDENT CONTRACTOR
     a.   In the performance of all services hereunder, RUTGERS shall be deemed
          an independent contractor and, as such, RUTGERS and its faculty,
          students, and staff shall not be construed to be employees or agents
          of SPONSOR and shall not be entitled to any benefits applicable to
          employees of SPONSOR.
          
     b.   Neither party is authorized or empowered to act as agent for the other
          for any purpose and shall not on behalf of the other enter into any
          contract, warranty, or representation as to any matter.  Neither shall
          be bound by the acts or conduct of the other.
          
13.  PUBLICITY
     Neither party shall use the name of the other party, nor of any member of
the other party's staff, in connection with any publicity without the prior
written approval of the other party.  This shall not include RUTGERS internal
documents, annual reports and databases which are available to the public and
which identify the existence of the RESEARCH PROJECT by title, PRINCIPAL
INVESTIGATOR, SPONSOR, period of funding, amount of award, and an abstract of
project.

14.  WARRANTIES
     RUTGERS makes no warranties, expressed or implied, as to any matter
whatsoever, including, without limitation, the condition of the research or any
invention (s) or product (s) , whether tangible or intangible, conceived,
discovered, or developed under this AGREEMENT; or the ownership,
merchantability, or fitness for a particular purpose of the research or any such
invention or product.  RUTGERS shall not be liable for any direct,
consequential, or other damages suffered by any licensee or any others resulting
from the use of the research or any such invention or product.

     RUTGERS makes no representation or warranty regarding actual or potential
infringement of patents or copyrights of third parties, and SPONSOR acknowledges
that the avoidance of such infringement in the design, use, and sale of products
and processes related to this RESEARCH PROJECT shall remain the responsibility
of SPONSOR.

15.  INDEMNIFICATION
     SPONSOR agrees to indemnify and hold harmless RUTGERS, its employees and
agents against any liability, damages, loss or expense (including reasonable
attorney fees and expenses of litigation) arising out of the actions of the
SPONSOR, its employees or any Third Party acting on behalf of or under
authorization from SPONSOR in the performance of this AGREEMENT, except for the
sole negligent acts of RUTGERS, its employees and agents.

     Without limiting the foregoing, SPONSOR agrees to hold harmless, indemnify
and defend RUTGERS from all liabilities, demands, damages, expenses and losses

paragraph shall survive termination of this AGREEMENT.

16.  COMPLIANCE

obligations of the parties accrued prior to the effective date of termination of
this AGREEMENT.  Upon termination, RUTGERS will be reimbursed for all costs and
noncancelable commitments incurred in the performance of the research and not
yet paid for, such reimbursement together with other payments not to exceed the
total estimated project cost specified in Article 5.

19.  AGREEMENT MODIFICATION

                 OFFICE OF CORPORATE LIAISON AND TECHNOLOGY TRANSFER

                                  RESEARCH AGREEMENT
                                  Modification No. 2



     Research Agreement dated November 19, 1993 between Phytotech, Inc. and
Rutgers, The State University of New Jersey related to the work of Dr. Ilya
Raskin on the Development of Phytoremediation Technology.
     
     The purpose of this modification is to continue the Research Agreement for
three (3) years in accordance with the changes shown below and are referenced to
the corresponding paragraph number in the Agreement:
     
4.   PERIOD OF PERFORMANCE
     The period during which the RESEARCH PROJECT is to be performed shall run
from October 15, 1993 to August 14, 1994 and shall be extended from August 15,
1994 to August 14, 1997, and may be extended, renewed, or amended by the mutual
written agreement of both parties.

5.   REIMBURSEMENT OF COSTS
     SPONSOR shall reimburse RUTGERS for all direct and indirect costs incurred
in connection with the RESEARCH PROJECT each year pursuant to the costs shown in
the attached three (3) year budget (Attachment A), a total amount not to exceed
$1,100,000.  Any costs in excess of the yearly amounts specified must be
authorized as an amendment to this AGREEMENT by SPONSOR.  RUTGERS shall retain
title to equipment and supplies purchased with funds provided by SPONSOR under
this AGREEMENT.

6.   PAYMENT SCHEDULE
     Payments shall be made each year to RUTGERS by SPONSOR as follows:

     (1)  First payment representing 40% of the total yearly amount on or about
          the date of signing this Modification No. 2 and by August 15 of each 
          year thereafter.

     (2)  Second payment representing 30% of the total yearly amount by December
           15.

     (3)  Third payment representing 30% of the total yearly amount by April 15.

10.  INTELLECTUAL PROPERTY

     a.   All rights and title to Intellectual Property conceived and reduced to
          practice in the performance of this RESEARCH PROJECT shall belong to
          RUTGERS and shall be subject to the terms and conditions of this
          AGREEMENT.

     b.   RUTGERS will promptly notify SPONSOR once it has identified any
          potentially valuable Intellectual Property conceived and/or made or
          reduced to practice during the term of this AGREEMENT.  If SPONSOR
          requests in writing within ninety (90) days of such notification that
          a patent application or application for other Intellectual Property
          Protection be filed in the United States, RUTGERS shall promptly
          prepare, file, and prosecute such applications in RUTGERS' name using
          a firm or attorney that is chosen by RUTGERS, or at SPONSOR's option,
          an attorney selected by SPONSOR subject to RUTGERS approval.  SPONSOR
          shall bear all costs incurred in connection with such preparation,
          filing, prosecution, and maintenance of such applications.  


<PAGE>



          SPONSOR shall be given the opportunity to review and provide input on
          such applications to assure that SPONSOR's interests are covered. 
          RUTGERS shall keep SPONSOR advised as to all developments with respect
          to such applications and shall promptly supply SPONSOR copies of all
          papers received and filed in connection with the prosecution.
          
     c.   If SPONSOR does not request RUTGERS to file a patent application in
          the United States within said ninety (90) day period, or decides to
          discontinue the financial support of any patent prosecution, or fails
          to pay or agree to pay all patent costs in any country in a reasonable
          period of time before a bar date occurs for that country, RUTGERS may
          pursue whatever course it deems necessary to protect its Intellectual
          Property and RUTGERS shall have no further obligations to SPONSOR with
          regard to such Intellectual Property in such country.  In such event,
          such Intellectual Property shall not be subject to the terms of this
          AGREEMENT; provided, however, that if SPONSOR has made a timely
          request to file in the United States, but does not make such a request
          with respect to one or more other countries, and if RUTGERS decides to
          file a patent application in such other countries, RUTGERS shall
          provide written notice within a reasonable amount of time of such
          election to SPONSOR and a reasonable period of time thereafter in
          which to reconsider its support of Intellectual Property Protection.
          
11.  GRANT OF RIGHTS
          
     a.   If SPONSOR requests that a patent application be filed pursuant to
          section 10.b and 10.c., and if SPONSOR requests a license relating to
          such patent application within six (6) months of such request, RUTGERS
          hereby grants SPONSOR, to the extent it has the legal right to do so
          and commencing on the date of such request, subject to the provisions
          of section 11.b., a license relating to such Intellectual Property
          providing it does not unreasonably impair RUTGERS' rights to use and
          publish as set forth in Article 9.
          
     b.   During such six (6) month period, RUTGERS and SPONSOR agree to
          negotiate in good faith the terms and conditions of a license
          agreement which are satisfactory to both parties.  Such license
          agreement shall include a provision granting SPONSOR an exclusive or
          nonexclusive worldwide license, with a right to sublicense, for the
          duration of the protection afforded by United States and foreign law,
          in the field(s) of use for which the SPONSOR can demonstrate
          commercial intent.  However, in the event of disagreement, the
          disputed matters will be submitted for arbitration under the rules and
          procedures of the American Arbitration Association.
          
18.  TERMINATION
          
     This AGREEMENT may be terminated by either party by giving written notice
to the other party at least ninety (90) days in advance of the anniversary date
of each year which shall be August 15 of each year.  By such termination,
neither party may nullify the rights and obligations of the parties accrued
prior to the effective date of termination of this AGREEMENT.  Upon termination,
RUTGERS will be reimbursed for all costs and noncancelable commitments incurred
in the performance of the research and not yet paid for, such reimbursement
together with other payments not to exceed the total estimated project cost
specified in Article 5.

All other terms and conditions remain as originally stated.

TO:       Peter Day

FROM:     Andrew B. Rudczynski

SUBJECT:  Special Indirect Cost Return for Phytotech Agreement

- -----------------------------------------------------------------

     I am pleased to inform you that the University will return generated
indirect costs on the second 5-year contract from Phytotech, Inc.  These special
returns will be distributed as follows.  In consonance with the University's
current plan to provide the Advanced Technology Centers with transition support
during the NJCST's phase out of support, 100% of generated indirect costs will
be returned during years FY 98 and 99, corresponding to years 1 and 2 of the
Phytotech agreement. You have indicated that you will use all available funds in
the Phytotech agreement to support that program of research in project years one
and two.

     In FY 2000, FY 2001 and FY 2002, indirect costs will be charged against the
research contract, however, the University will return 2/3 of the generated IDC
to the project.  If Phytotech chooses to increase the annual amount of the
research agreement, this will result in no reduction of the research effort. 
Otherwise, the direct costs available to the project for Project years 3-5 will
be reduced by an amount equivalent to 1/3 of the generated indirect costs. 
Phytotech may provide the additional funds necessary to pay indirect costs in
project years 3-5.

     In either case, all indirect costs not paid in years 3-5 will be due in
equal amounts over the 3 years corresponding to "project years 6, 7 and 8,"
independent of any other agreements the University has with Phytotech at the
time.  If at any time during project years 3-5 products sales occur such that
they trigger royalty payments to the University under the licensing agreement
dated _____________, then all unpaid indirect cost amounts will be due
immediately.

     The attached table outlines the IDC payment schedule.

                                                  Agreed and accepted,


                                                   Burt Ensley

     THIS AGREEMENT is made and entered into by and between the Florida State
University, for and on behalf of the Florida Board of Regents, a public
corporation of the State of Florida (hereinafter University) and Phytotech, Inc.
(hereinafter Contractor).  For and in consideration of the mutual promises,
covenants, and obligations contained herein, the parties do agree as follows:

1.   SCOPE OF SERVICES

2.   CONTRACTOR RESPONSIBILITIES

     The Contractor is responsible for the professional quality, technical

furnished by the Contractor under this Agreement.  The Contractor shall, without
additional compensation, correct or revise any errors, omissions, or other
deficiencies in its services and reports.

3.   INDEPENDENT CONTRACTORS

     By this Agreement the parties intend to establish between them the
relationship of mutually independent contractors.  Each party and the officers,

deemed by virtue of this Agreement to be the officers, employees, or agents of
the other party nor in privity of contract therewith.

4.   DESIGNATION OF REPRESENTATIVES

which specifies the period of the extension and the criteria remaining to be met
by the Contractor, which document shall be properly executed prior to the
expiration of the Agreement period or any previous extension period.

7.   FORCE MAJEURE

     If the Contractor's performance under this Agreement or any obligation
hereunder is prevented, restricted or interfered with by reason of FORCE
MAJEURE, i.e., any act or condition totally beyond the Contractor's control and
without its fault or negligence, the Contractor, upon giving prompt notice to
the University, shall be excused from such performance to the extent of such
prevention, restriction, or interference; provided, however, that the Contractor
shall take all reasonable steps to avoid or remove such causes of nonperformance
and shall continue performance hereunder with dispatch whenever such causes are
removed; provided further, that if it appears that the time of delivery or
performance will be extended past the terms set forth herein, a written
extension of time will be negotiated by the parties.

8.   AVAILABILITY OF FUNDS AND COMPENSATION

     The State of Florida and the University's performance and obligation to pay
under this Agreement is contingent upon an annual appropriation by the
Legislature and funding by the


                                          2

University of the deliverables listed in the Schedule of Deliverables and
Payments in Attachment A.  To receive payments, the Contractor shall submit
invoices (in U.S. dollars) to the address stated on the purchase order in
accordance with the Schedule of Deliverables and Payments in Attachment A and in
sufficient detail for a proper preaudit and postaudit thereof.  The Contractor
shall certify on each invoice that all deliverables covered by the invoice have
been accomplished.  The certification statement shall carry an original
signature of an authorized, knowledgeable official of the Contractor.

     The University agrees to pay the Contractor through electronic funds
transfer.  The Contractor agrees that in the event the electronic address
provided to the University is incorrect, the University will not be held liable
for any funds lost in transit.

9.   FINAL PAYMENT

University within sixty (60) days from the expiration date of this Agreement. 
If the Contractor fails to do so, all rights to payment shall be forfeited after
the deadline and the University will not honor any request submitted after the
aforementioned deadline, unless through no fault of the Contractor.

10.  TRAVEL

     Whenever travel costs are included in the Agreement or attachments to the
Agreement, the provisions of Section 112.061 and 240.241(13).  FLORIDA STATUTES,
shall govern as to reimbursement of cost.

current cost or pricing data.  If it is determined that such data are not

accordingly and the Agreement shall be modified to reflect the reduction.

within 45 days following the time the overpayment and/or disallowance is
discovered unless otherwise authorized by the University in writing.  In
addition the Contractor agrees to exclude from its billings any amounts
disallowed by the Agency or the University per the terms of the Agreement.

another party nor subcontract for any of the work contemplated under this
Agreement without prior written approval of the University, subject to the
approval of the Agency.  No such approval by the University of any assignment or
subcontract shall be deemed in any event or in any manner to provide for the
incurrence of any obligation of the University in addition to the total dollar
amount agreed upon in this Agreement.  All such assignments or subcontracts
shall be subject to the conditions of this Agreement and to any additional
conditions of approval which the University shall deem necessary.

15.  INDEMNIFICATION

indemnify, defend and hold the University harmless for all claims, suits,
judgments or damages, including court costs and attorney fees, arising out of

(4)  52.247-64, Preference for Privately Owned U.S.-Flagged Commercial Vessels
(46 U.S.C. 1241) (flow down not required for subcontracts awarded beginning May
1, 1996).

(d)  The Contractor shall include the terms of this clause, including this
paragraph (d), in subcontracts awarded under this contract.


I.4  252.232-7007 LIMITATION OF GOVERNMENT'S OBLIGATION. (AUG 1993)

(a)  Contract line item 0001 is incrementally funded.  For this item, the sum of
$186,660.00 of the total price is presently available for payment and allotted
to this contract.  An allotment schedule is set forth in paragraph (i) of this
clause.

(b)  For item(s) identified in paragraph (a) of this clause, the Contractor
agrees to perform up to the point at which the total amount payable by the
Government, including reimbursement in the event of termination of those item(s)
for the Government's convenience, approximates the total amount currently
allotted to the contract.  The Contractor will not be obligated to continue work
on those item(s) beyond that point.  The Government will not be obligated in any
event to reimburse the Contractor in excess of the amount allotted to the
contract for those item(s) regardless of anything to the contrary in the clause
entitled "Termination for Convenience of the Government." As used in this
clause, the total amount payable by the Government in the event of termination
of applicable contract line item(s) for convenience includes cost, profit, and
estimated termination settlement costs for those items(s).

(c)  Notwithstanding the dates specified in the allotment schedule in paragraph
(i) of this clause, the Contractor will notify the Contracting Officer in
writing at least ninety days prior to the date when, in the Contractor's best
judgment, the work will reach the point at which the total amount payable by the
Government, including any cost for termination for convenience, will approximate
85 percent of the total amount then allotted to the contract for performance of
the applicable item(s).  The notification will state (1) the estimated date when
that point will be reached and (2) an estimate of additional funding, if any,
needed to continue performance of applicable line items up to the next scheduled
date for allotment of funds identified in paragraph (i) of this clause, or to a
mutually agreed upon substitute date.  The notification will also advise the
Contracting Officer of the estimated amount of additional funds that will be
required for the timely performance of the item(s) funded pursuant to this
clause, for subsequent period as may be

<PAGE>

CONTINUATION SHEET                 DAAE30-97-C-1081              PAGE 19 of


specified in the allotment schedule in paragraph (i) of this clause, or
otherwise agreed to by the parties.  If after such notification additional funds
are not allotted by the date identified in the Contractor's notification, or by
an agreed substitute date, the Contracting Officer will terminate any item(s)
for which additional funds have not be allotted, pursuant to the clause of this
contract entitled "Termination for Convenience of the Government."

(d)  When additional funds are allotted for continued performance of the
contract line item(s) identified in paragraph (a) of this clause the parties
will agree as to the period of contract performance which will be covered by the
funds.  The provisions of paragraph (b) through (d) of this clause will apply in
like manner to the additional allotted funds and agreed substitute date, and the
contract will be modified accordingly.

(e)  If, solely by reason of failure of the Government to allot additional
funds, by the dates indicated below, in amounts sufficient for timely
performance of the contract line item(s) identified in paragraph (a) of this
clause, the Contractor incurs additional costs or is delayed in the performance
of the work under this contract and if additional funds are allotted, an
equitable adjustment will be made in the price or prices (including appropriate
target, billing, and ceiling prices where applicable) of the item(s), or in the
time of delivery, or both.  Failure to agree to any such equitable adjustment
hereunder will be a dispute concerning a question of fact within the meaning of
the clause entitled "Disputes."

(f)  The Government may at any time prior to termination allot additional funds
for the performance of the contract line item(s) identified in paragraph (a) of
this clause.

(g)  The termination provisions of this clause do not limit the rights of the
Government under the clause entitled "Default." The provisions of this clause
are limited to the work and allotment of funds for the contract line item(s) set
forth in paragraph (a) of this clause.  This clause no longer applies once the
contract is fully funded except with regard to the rights or obligations of the
parties concerning equitable adjustments negotiated under paragraphs (d) or (e)
of this clause.

(h)  Nothing in this clause affects the right of the Government to terminate
this contract pursuant to the clause of this contract entitled "Termination for
Convenience of the Government."

(i)  The parties contemplate that the Government will allot funds to the
contract in accordance with the following schedule:

I.5  252.247-7023 TRANSPORTATION OF SUPPLIES BY SEA. (NOV 1995)

(a)  Definitions.  As used in this clause --

Contractor or any subcontractor.

(2)  "Department of Defense" (DoD) means the Army, Navy, Air Force, Marine
Corps, and defense agencies.

(3)  "Foreign flag vessel" means any vessel that is not a U.S.-flag vessel.

(4)  "Ocean transportation" means any transportation aboard a ship, vessel,
boat, barge, or ferry through international waters.

any level below the prime contractor whose contractual obligation to perform
results from, or is conditioned upon, award of the prime contract and who is
performing any part of the work or other requirement of the prime contract.
However, effective May 1, 1996, the term does not include a supplier,
materialman, distributor, or vendor of commercial items or commercial
components.

(6)  "Supplies" means all property, except land and interests in land, that is
clearly identifiable for eventual use by or owned by the DoD at the time of
transportation by sea.

(i)  An item is clearly identifiable for eventual use by the DoD if, for
example, the contract documentation contains a reference to a DoD contract
number or a military destination.

(ii) "Supplies" includes (but is not limited to) public works; buildings and
facilities; ships; floating equipment and vessels of every character, type, and
description, with parts subassemblies, accessories, and equipment; machine
tools; material; equipment; stores of all kinds; end items; construction

transportation by sea of any supplies to be furnished in the performance of this
contract.  The Contractor and its subcontractors may request that the
Contracting Officer authorize shipment in foreign-flag vessels, or designate
available U.S.-flag vessels, if the Contractor or a subcontractor believes that

(2)  The freight charges are inordinately excessive or unreasonable; or

(3)  Freight charges are higher than charges to private persons for
transportation of like goods.

(c)  The Contractor must submit any request for use of other than U.S.-flag
vessels in writing to the Contracting Officer at least 45 days prior to the
sailing date necessary to meet its delivery schedules.  The Contracting Officer
will process requests submitted after such date(s) as expeditiously as possible,
but the Contracting Officer's failure to grant approvals to meet the shipper's
sailing date will not of itself constitute a compensable delay under this or any
other clause of this contract.  Requests shall contain at minimum --

(1)  Type, weight, and cube of cargo;

(2)  Required shipping date;

(3)  Special handling and discharge requirements;

(4)  Loading and discharge points;

operating carrier's ocean bill of lading, which shall contain the following
information --

(1)  Prime contract number;

a representation that to the best of its knowledge and belief --

(1)  No ocean transportation was used in the performance of this contract;

(2)  Ocean transportation was used and only U.S.-flag vessels were used for all
ocean shipments under the contract;

(3)  Ocean transportation was used, and the Contractor had the written consent
of the Contracting Officer for all non-U.S.-flag ocean transportation; or

(4)  Ocean transportation was used and some or all of the shipments were made on
non-U.S.-flag vessels without the written consent of the Contracting Officer.
The Contractor shall describe these shipments in the following format:

     ITEM                     CONTRACT                 QUANTITY

               CLEARANCE OF TECHNICAL INFORMATION FOR PUBLIC RELEASE

                                    INSTRUCTIONS

IF AUTHOR/PRODUCER IS PICATINNY-BASED:
     Picatinny-based authors/producers are responsible for initiating the
clearance process and ensuring that their material is approved for public
release.  This is accomplished by attaching one copy of the material
(manuscript, photos, videotapes and any other material that requires clearance)
to this form and obtaining the necessary signatures.  When clearance is granted,
the Picatinny Public Affairs Office (the last office in the clearance process)
will forward one copy of this form along with the attached material to the ARDEC
Technical Library for archival purposes and provide another copy of this form to
the author/producer.  It is the author/producer's responsibility to notify all
interested parties of the release approval and to make subsequent distribution.

IF AUTHOR/PRODUCER IS A CONTRACTOR:
     A contractor initiates the clearance process by forwarding the material 
to a Picatinny sponsor, who in turn begins the clearance process in the same 
manner as a Picatinny-based request.  When clearance is granted, the 
Picatinny Public Affairs Office (the last office in the clearance process) 
will forward one copy of this form along with the attached material to the 
ARDEC Technical Library for archival purposes, and provide another copy of 
the form to the Picatinny sponsor.  It is the Picatinny sponsor's 
responsibility to notify the contractor and any other interested parties of 
the release approval and to coordinate subsequent distribution with the 
contractor.  Because contractor-submitted videotape material requires 
clearance at the Defense Department level, recommend that these submissions 
be made at least 90 days prior to the projected public release date. Only 
Picatinny-related portions of multi-topic videotapes will be reviewed here.

RECOMMENDED DISTRIBUTION:
     Each signator in the REQUIRED APPROVALS section recommends distribution
based on the categories listed at the bottom of the form.  The approved
distribution is circled at the bottom of the form and will equal the most
stringent distribution category selected by the signators.

- --------------------------------------------------------------------------------

                                      COMMENTS

(Use this space, and additional pages as necessary, to make additional 
remarks or written changes to the submitted material.  If changes are made 
directly on the material, a note to that effect in the REQUIRED APPROVALS 
section under "Remarks" is all that's necessary.)

PICATINNY ARSENAL PUBLIC AFFAIRS OFFICE; DSN 880-6365, (201) 724-6365.

1.1       GENERAL DESCRIPTION

          Parsons Engineering Science, Inc. (Parsons ES), CONTRACTOR, is under
contract to Air Mobility Command (AMC), CLIENT, to perform remedial treatability
study services at the CSSA oxidation pond (SWMU 0-1).  All work must meet the
requirements established in this statement of work.

          The CSSA site is a 4,000-acre tract located in northwestern Bexar
County less than 19 miles northwest of San Antonio, Texas, and 10 miles south of
Boerne.  CSSA began operations in the early 1900s as a military installation and
weapons storage and refurbishing facility.  The site operations consisted of an
open burn/open detonation (OB/OD) disposal area known as solid waste management
unit B-20 (SWMU B-20).  During the active life of the facility, there were no
recorded releases from the area.  The B-20 site (shown in Figure 1) was
investigated beginning in 1992.  A brief discussion of site investigation
results is included as an attachment to this statement of work.

1.2       SCOPE OF WORK

          The B-20 area has been identified with contamination exceeding cleanup
levels in surface soils.  This scope of work (SOW) includes requests for costs
associated with a laboratory benchscale treatability test of phytoremediation.
The purpose of the studies is to provide data for the feasibility of
phytoremediation at the B-20 site.
