Item 1. BUSINESS

The Company
- -----------

         AMBI Inc. (the "Company") is a New York corporation which was
incorporated on June 29, 1983. The Company currently concentrates its business
in two areas: Pharmaceuticals and Nutrition Products. The Company engages in the
following activities for these areas: research, development, manufacturing, and
sales.

   
         On December 12, 1996, the Company completed the sale of its UK-based
food ingredients subsidiary, Aplin & Barrett Limited ("A&B") to Burns Philp &
Company Limited ("BP") for $13.5 million in cash and the return to the Company
of 2.42 million shares of the Company's Common Stock held by BP. In addition, BP
provided the Company with a revolving line of credit of up to $2.5 million. Any
borrowings under this line of credit can be forgiven under certain
circumstances. As of the date of filing this Form 10-K, no amount has been drawn
under this line of credit. The sale included the Company's nisin-based food
preservative business. The Company retained exclusive rights to its nisin-based
pharmaceutical and animal healthcare business. Substantially all of the
Company's earnings through the date of sale had been generated by this
subsidiary. This loss of revenue contributed to an operating loss of $16.6
million in fiscal 1997, compared with an operating loss of $4.6 million in
fiscal 1996. The sale of A&B did generate cash proceeds which provided
adequately for the Company's short-term capital requirements following the sale.
The Company has recently reinvested some of the proceeds from this sale into the
acquisition of Nutrition 21, which may replace the potential to generate
revenues. See Item 7 -- Management's Discussion and Analysis of Financial
Condition and Results of Operations and Item 13 --Certain Relationships and
Related Transactions.
    

         On August 11, 1997, the Company acquired the entire beneficial interest
in Nutrition 21, a limited partnership. Nutrition 21 is engaged in the business
of developing, producing, and marketing proprietary nutrition products and
dietary supplements. The purchase price for the acquisition was $10,000,000 (the
"Cash Purchase Price"), plus 500,000 restricted shares of Common Stock of the
Company, and additional cash payments which are contingent upon the achievement
of certain sales levels in the next four years. The Company will also pay
royalties to the sellers on sales of certain patented products. Part of the Cash
Purchase Price was provided pursuant to a Revolving Credit and Term Loan
Agreement (the "Loan Agreement") with State Street Bank and Trust Company
("SSBT") and the remainder came from internal working capital. The loans bear
interest at SSBT's prime rate plus one percent and are due February 1, 1998
unless extended pursuant to certain conditions set forth in the Loan Agreement.

                                       3

Nutrition Products

         Nutrition Products may take the form of either foods or beverages and
can include vitamins, minerals, enteral and parenteral supplements, other
dietary supplements, healthy foods, functional foods, special dietary foods,
medical foods, and are sometimes referred to colloquially as nutraceuticals.
Medical Foods are foods that supply particular dietary needs or that may aid in
the dietary management of diseases or conditions.

         In October, 1995, the Company acquired an exclusive license for a
Medical Food from a division of Orion Corporation ("Orion"), the largest
pharmaceutical company in Finland, to sell Orion's patented salt alternative in
the United States. The Company began selling the salt alternative in April 1996
under the trademark CardiaTM Salt Alternative in Florida and Pennsylvania, and
announced the national availability of Cardia Salt Alternative in January 1997.
This product has significantly less sodium than regular salt and contains
potassium and magnesium, essential minerals that may help in the dietary
management of high blood pressure. High blood pressure, or hypertension, affects
approximately 50 million Americans. The Company has conducted and is continuing
to conduct clinical trials on Cardia Salt Alternative that demonstrate its
safety and effectiveness as a dietary aid in the management of high blood
pressure. For example, two separate studies released in April and May 1997,
respectively, compared the use of Cardia Salt Alternative and regular salt in
hypertensive patients and found reduced blood pressure in the patients who used
Cardia Salt Alternative.

         The Company is evaluating other proprietary Nutrition Products in the
areas of cardiovascular disease, diabetes, infectious disease, and
gastrointestinal disorders.

         The Company markets Nutrition Products that are regulated by the 1994
Dietary Supplement Health and Education Act (DSHEA) and the Orphan Drug Act to
physicians, pharmacists, dietitians, and patients, and supports the use of these
products with data from clinical studies. In addition, the Company intends to
conduct its own clinical studies to further strengthen the clinical and
scientific rationale for these products.

         Nutrition 21
         ------------

         Nutrition 21 develops, manufactures, and markets essential trace
elements used primarily as ingredients in nutritional supplements. Currently,
Nutrition 21's primary product is chromium picolinate, which is protected by 4
patents which cover the composition and its use as a dietary supplement. The
composition patent is exclusively licensed for its duration to Nutrition 21 by
the United States Department of Agriculture ("USDA"), and expires August 8,
2000. Nutrition 21 owns patents for the use of chromium picolinate in the
management of high cholesterol, glucose control, and the conversion of fat to
lean body mass, which patents expire in 2009. Chromium picolinate is marketed by
Nutrition 21 under its registered trademark Chromax. In addition, Nutrition 21
also markets zinc picolinate, manganese picolinate, and selenium formulations.


                                       4
<PAGE>

Nutrition 21 has funded and continues to fund research studies investigating the
uses of chromium picolinate and other micro-nutrients or minerals as dietary
supplements with preventative and therapeutic benefits to humans.

         Nutrition 21 has its products manufactured and formulated to its
specifications by contract manufacturers as bulk raw materials. Nutrition 21
then sells the raw materials to customers who incorporate them into over 900
finished products such as vitamin/mineral formulas, dietary supplements, baked
goods, beverages and other products. These products are sold by the customers
under a variety of brands throughout the world through natural/health food
stores, supermarkets, and drug stores, and also through direct sales and
catalogues sales. Nutrition 21 has approximately 50 customers. During the year
ended June 30, 1997, Leiner Health Products accounted for 14.8% of Nutrition
21's revenues.

         In 1996, chromium picolinate was approved by the U.S. Food and Drug
Administration ("FDA") for use as a supplement in animal feed for swine.

         Nutrition 21 is developing new micro-nutrients such as arginine
silicate for which Nutrition 21 has an allowed patent, and magnesium taurate for
which Nutrition 21 has patent protection, and may commercialize these or other
products.

Pharmaceuticals

         Antibacterials
         --------------

         The Company is developing the compound nisin, a member of the lanthocin
class of peptides, in different proprietary formulations as a potential
treatment for diseases caused by serious bacterial infections, including
hospital-acquired infections, for infections of the colon, and for ulcer
disease. In addition, the Company is developing lysostaphin, an enzyme, as a
potential treatment for hospital-acquired infections.

         During each phase of the drug development process, scientific and
business evaluations of the cost, risk, and potential return on investment are
undertaken on a product by product basis. There can be no assurance that the
development programs will continue should there be a negative evaluation of the
cost and risks of continuing to develop a particular product.

         The development of nisin and lysostaphin as therapeutic agents for
these and other indications can be a long, difficult, and expensive process.
There can be no assurance that a drug product will be approved by the FDA or its
regulatory equivalent in a foreign country. Currently the Company's nisin
formulations for treatment of ulcers have been successfully tested for safety in
human studies outside the United States. Human studies have also been successful
in confirming that the Company's nisin formulations can be delivered orally to
the colon for treatment of infections of the colon. None of the human clinical
studies have tested for efficacy. The use of nisin and lysostaphin to treat
hospital-acquired infections is still being investigated in animal studies.

After the effectiveness of a treatment has been successfully demonstrated in
human 


                                       5
<PAGE>

clinical studies, an application for final approval is submitted for review by
the FDA. Such review can take one or more years and can result in the
requirement that further studies be undertaken. The Company does not anticipate
that any of its pharmaceutical products will be available for marketing before
1999. See also "Governmental Regulation."

         Infections of the colon --- The Company has developed an oral delivery
form of nisin for the treatment of antibiotic-associated diarrhea caused by
Clostridium difficile (C. difficile) and for the eradication of Vancomycin
Resistant Enterococci (VRE) that inhabit the colon. These infections can be
especially severe for patients with cancer, AIDS, or those who are in intensive
care units.

         Nisin is able to kill C. difficile and VRE without affecting the normal
flora of the colon. In June 1997, the Company announced results of a human study
demonstrating that nisin was successfully delivered orally, in the form of a
tablet, to the colon. Nisin has the potential to be the first peptide that can
be taken orally as a treatment for a serious infectious disease of the colon.

         Ulcer --- The Company has developed a different oral form of nisin for
the eradication of Helicobacter pylori (H. pylori), the causative agent of
peptic ulcer disease. Most ulcers, as well as other gastric disorders such as
chronic gastritis and cancer of the stomach, are caused by H. pylori, a
bacterium that colonizes the human stomach.

         Nisin has been shown to be safe in two clinical studies in almost 100
human subjects. Recent studies in animals have confirmed nisin's efficacy
against H. pylori.

         Hospital-acquired infections -- Hospital-acquired infections occur most
frequently among the sickest patients, such as those people who are
immunocompromised or have just had surgery. For some infections e.g., those
caused by Methicillin Resistant Staphylococcus Aureus (MRSA), Vancomycin
Resistant Staphylococcus Aureus (VRSA), and VRE, there are now virtually no
therapeutic agents that show consistent high rates of efficacy, and therefore,
certain serious infections can often be fatal.

         When administered by injection, both nisin and lysostaphin have been
found to be effective in curing lethal systemic bacterial infections in mice. In
September 1997, the Company announced results of a study demonstrating that
lysostaphin successfully treated endocarditis caused by MRSA bacteria in
rabbits.

Pharmaceutical Partners

         In March 1994, the Company entered into an exclusive License and Supply
Agreement with the Astra/Merck Group of Merck & Co., Inc. (now Astra Merck) to

develop and market in the U.S. drug products based on nisin for the treatment of
gastrointestinal disorders, including ulcers. The agreement provides for the
Company to perform raw material studies on nisin and toxicological studies on a
prototype formulation. Astra Merck is responsible for all clinical trials and
for obtaining FDA approvals of drug products. The agreement provides for
milestone and 


                                       6
<PAGE>

royalty payments to the Company, and for the purchase of raw materials from the
Company.

         In March 1996, the Company entered into an exclusive Agreement with
Nippon Shoji Kaisha, Ltd. of Osaka, Japan, to develop and market in Japan,
certain Asian countries, Australia and New Zealand drug products based on nisin
for the treatment of hospital acquired infections and infections of the colon.
The agreement provides for the Company to perform certain research and
development activities and to provide semi-annual reports thereon to NSK. NSK
provides the Company with research funds for a period of three years, milestone
payments and royalties, and agrees to make certain purchases of raw materials
from the Company. In connection with the agreement, NSK invested $2 million in
the Company's Common Stock and loaned the Company another $2 million which can
be repaid, at the Company's option, with the Company's Common Stock upon meeting
certain milestones.

Dairy Hygiene Products

         The Company manufactures and sells a preparation of nisin which the
Company markets under its trademark Ambicin(R)N, which is the active ingredient
in an animal hygiene product applied to the udders of lactating dairy cattle
before and after milking. The Company has developed a germicidal solution based
on Ambicin N that is applied to the teats of cows as a dip or spray before and
after milking in order to prevent the spread of mastitis. This dermatological
preparation is a potent broad spectrum germicide that acts rapidly against the
bacteria that cause mastitis.

         On December 15, 1988, the Company entered into a License and License
Option Agreement ("Agreement"), as amended November 25, 1991, July 1, 1993 and
February 9, 1996, with Babson Brothers ("Babson") of Naperville, Illinois. Under
the Agreement, Babson is granted licenses for certain exclusive territories
which include North America and Puerto Rico to manufacture and market Ambicin N
based mastitis preventatives, other than udder wipes, which are exclusively
reserved for manufacture and marketing by the Company. The Company supplies
Ambicin N to Babson. In July 1991, Babson commenced manufacturing and marketing
an Ambicin N-based teat dip product in the U.S. under its trademark Consept.

         Under a July 1991 agreement with CFPI, a French specialty chemical
manufacturer, the Company licensed CFPI to manufacture and market Ambicin
N-based formulations for use as topical germicides in the prevention of mastitis
in nine European countries. CFPI introduced its product in France in 1992. The
agreement with CFPI was terminated as of July 31, 1997, and the Company is
considering other approaches to the European market.


         The Company developed a moistened towel using an Ambicin N-based
formulation that is for use in preparing dairy cows for milking. Trials in dairy
cows at Cornell Veterinary College showed the product to be effective. The
Company launched the product under its trademark Wipe OutTM Dairy Wipes on a
test basis in February 1996, and nationally in April 1996.


                                       7

Governmental Regulation

         Healthcare
         ----------

         Products which are intended for use in the diagnosis, cure, mitigation,
treatment or prevention of disease in humans or animals are subject to extensive
governmental regulation. All such products must undergo extensive
characterization, and are subject to regulation for quality assurance,
toxicology and safety. Products containing such agents must undergo thorough
preclinical and clinical evaluations of performance as to safety and efficacy
under approved protocols.

         The Company intends to pursue regulatory approval for the
pharmaceutical and related uses of its drug products. The Company's proposed
pharmaceutical products will be subject to the regulatory approval processes for
new drugs. To take a pharmaceutical product from the discovery stage through
research and preclinical development to the point where the Company and/or its
partners can make the necessary filings (to the FDA and governmental agencies
outside the U.S.) to conduct human clinical trials may take several years.
Regulatory requirements for human clinical trials are substantial, depend upon a
variety of factors, vary by country, and will further add to the time necessary
to determine whether a product candidate can be approved for human use. The
Company does not have any pharmaceutical products which have completed this
process. All of these products are in various stages of preclinical or clinical
development. There can be no assurance that the Company's proposed drug products
will prove to be safe and effective under these regulatory procedures. See also
"Pharmaceuticals -- Antibacterials."

         Depending upon the ingredients of a specific product, some nutrition
products can be marketed in the U.S. under DSHEA or the Orphan Drug Act. The
Company's Nutrition 21 and Cardia Salt Alternative products fall in regulatory
categories that do not require FDA approval for marketing, but are subject to
monitoring by the FDA. In addition to FDA regulations, the Federal Trade
Commission ("FTC") regulates product advertising claims. Prior to the Company's
acquisition of Nutrition 21, Nutrition 21 and the FTC entered into a consent
agreement, which culminated in an FTC order that, among other things, requires
that claims for dietary supplements be supported by competent and reliable
scientific evidence. The order requires that Nutrition 21 advise its customers
who resell chromium picolinate to the public not to make claims which are not
supported by competent and reliable scientific evidence.

Research and Development


         The Company conducts research and development to expand uses of its
pharmaceutical product candidates, to identify new antibacterial products, and
to improve the production processes for the Company's antibacterial products. In
addition, the Company conducts preclinical, formulation, and clinical trials on
its Nutrition Products and product candidates. These efforts are conducted with
industrial and academic co-workers in various countries. During the fiscal year
ended June 30, 1997, approximately $4,833,000 was spent on research and
development by the Company.



                                       8

increasing lean body mass, and other patents relating to, among other things,
magnesium taurate treatments of cardiac conditions.

         Under an agreement with the University of Maryland, the Company has
obtained exclusive licenses under patents and applications relating to the
cloning, expression and alteration of genes encoding nisin, subtilin, and
related peptides, and their production and compositions. The licenses include
exclusive rights under a basic patent, which expires in 2010, for making
recombinant lanthocins.

         Under an agreement with the Institute of Food Research, Norwich, U.K.,
the Company owns certain strains of bacteria producing nisin and related
patents, and may obtain exclusive licenses to certain nisin-related mutants and

related patents.

         Under an agreement with the New York University Medical Center, the
Company owns patent rights to the parenteral treatment of drug-resistant
bacterial infections with lanthocins and other agents.

         Under a Pre-Clinical Study Agreement for work being performed at the
McGuire Veterans Administration Hospital, the Company owns patent rights to the
parenteral treatment of drug-resistant bacterial infections with lanthocins and
other agents.

         The Company maintains trade secret protection for bacterial strains,
technical know-how, 


                                       9
<PAGE>

and other information it considers proprietary and beneficial for the
manufacture, use, regulatory approval, and marketing of the Company's products.

         The Company maintains non-disclosure safeguards, including
confidentiality agreements, with employees, certain consultants, and Scientific
Advisory Board members. There can be no assurance, however, that others may not
independently develop similar technology or that secrecy will not be breached
despite any agreements which exist.

Manufacturing

         The Company's products, e.g. Ambicin N, Cardia Salt Alternative, and
Nutrition 21's products, are manufactured for the Company by subcontractors who
manufacture to the Company's specifications and use the Company's manufacturing
technology. The Company subcontracted purchases of nisin from BP for
pharmaceutical and animal healthcare uses from December 11, 1996 until September
26, 1997. Nisin-based products for pharmaceutical and animal healthcare are
currently being manufactured for the Company by another subcontractor. The
Company believes that these manufacturers can be readily replaced except that a
delay of a few months might be required to commence nisin production at another
facility. However, the Company believes that it has adequate inventory of
product, including nisin, to accommodate a suspension in the manufacture of any
of its products. There are numerous sources of supply for all of the raw
materials used in the manufacture of the Company's products.

Marketing and Sales

         The Company markets and distributes its nutrition product lines through
a network of distributors and agents, and markets its Wipe Out Dairy Wipes
product through direct sales efforts. See "Nutrition Products" and "Dairy
Hygiene Products" for further discussion of the marketing and distribution of
specific products. There were no significant unaffiliated customers comprising
over 10% of sales during the 1997 or 1996 fiscal years. Sales to BP constituted
12% of consolidated sales in the 1996 fiscal year but were not significant in
the 1997 fiscal year due to the sale of A&B to BP.


Financial Information About Industry Segments

         The Company's business historically was in a single industry segment,
the research, development, production and marketing of antibacterial proteins
for various applications. In April 1996, the Company began selling a salt
alternative as a Medical Food that may help in the dietary management of
hypertension, and on August 11, 1997 the Company acquired Nutrition 21 which
sells nutritional supplements. For financial data pertaining to the amount of
revenue and operating profit and loss of the Company, see "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Financial Statements."

Item 7 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
       OF OPERATIONS

         The following discussion should be read in conjunction with the
Consolidated Financial Statements and related notes thereto of the Company
included elsewhere herein.

General

         The Company's historical revenues have been primarily attributable to
sales of its own products. The Company has acted in the past as selling agent
for certain products of both affiliated as well as unaffiliated companies.
Effective July 1, 1995, the Company assumed responsibility for selling products
in the US on behalf of an affiliated company, Burns Philp & Company Ltd. ("Burns
Philp"). This relationship was discontinued effective September 11, 1996. The
Company also receives royalty income from users of its patented technology and
milestone payments from research partners.

         The Company completed the sale of its UK-based food preservative
business, Aplin & Barrett, Ltd. ("A&B"), to Burns Philp on December 12, 1996. As
a result, the operations of A&B are included in the financial statements through
that date. The decision to sell the UK-based food preservative business, A&B to
Burns Philip was made by the Company's Board of Directors in 1996. At that time
directors unaffiliated with Burns Philp constituted a majority of the Board of
Directors. The Board's decision was based upon its view that the Company's
resources would be more profitably employed in pursuing the development of its
own products and that such development would be facilitated by the cash proceeds
of the sale of A&B. After the sale, Burns Philip owns approximately 40% of the
Company's Common Stock. See "Item 12 -- Security Ownership of Certain Beneficial
Owners and Management."

         Cost of sales includes both direct and indirect manufacturing costs.
Research expenses include internal expenditures as well as expenses associated
with third party collaborators. Selling, general and administrative expenses
include salaries and overheads, third party fees and expenses, and costs
associated with the selling of the Company's products. The Company capitalizes
patent costs and amortizes them over periods of nine months to fifteen years.


                                       15

<PAGE>

Results of Operations

         The Company has an accumulated deficit due primarily to the write-off
of purchased goodwill (amortized over five years from 1986 - 1990) and purchased
research and development costs (written-off in the year ended June 30, 1993) in
connection with the BP Transactions, and the current year loss.

Three years ended June 30, 1997, 1996 and 1995

Revenues

- --------

         Revenues decreased 30% to $11.3 million in the fiscal year ended June
30, 1997 ("fiscal 1997") from $16.0 million in the fiscal year ended June 30,
1996 ("fiscal 1996"). A decline of $7.4 million was attributable to the
divestiture of the Company's A&B subsidiary which occurred December 12, 1996.
Sales as a percentage of total revenues attributable to A&B were 53%, 81%, and
100% of total revenues in fiscal 1997, fiscal 1996, and fiscal 1995,
respectively. A further $0.9 million decline was due to lower receipts of
milestone and research payments from third party research collaborators. Sales
of new products launched in 1996 fiscal year increased $3.6 million during the
year - Cardia Salt Alternative ($3.6 million in fiscal 1997 up from $0.7 million
in fiscal 1996) and Wipe Out Dairy Wipes ($1.2 million in fiscal 1997 up from
$0.5 million in fiscal 1996).

         Revenues increased 37% to $16.0 million in fiscal 1996 from $11.7
million in the fiscal year ended June 30, 1995 ("fiscal 1995"). $1.2 million of
this increase was attributable to new products launched during the year - Cardia
Salt Alternative ($0.7 million) and Wipe Out Dairy Wipes ($0.5 million). A
further $0.4 million in new business was recorded as a result of the Company
assuming responsibility for selling products in the US on behalf of an
affiliate. Sales of Nisaplin, a food preservative sold by A&B, increased 6% in
fiscal 1996; and accounted for 65% of the total sales, compared with 77% in
fiscal 1995. Other operating income increased by $1.4 million due to milestone
and research payments received from third party research collaborators.

Cost of Sales
- -------------

   
         Cost of sales was $5.0 million in fiscal 1997, a decline of 22% from
the fiscal 1996 figure of $6.4 million. As a percentage of revenues, it
increased to 44% in fiscal 1997, compared to 40% in fiscal 1996, due principally
to additional costs asssociated with production of animal health products.
    

         Cost of sales was $6.4 million in fiscal 1996, an increase of 95% from
the fiscal 1995 figure of $3.3 million. As a percentage of revenues, it
increased to 40%, compared to 28% in fiscal 1995. This was largely due to a
change in the sales mix, with a higher proportion of sales representing lower
margin products (for which the company acted solely as a distributor) versus the
prior year.



                                       16

Selling, General and Administrative Expenses
- --------------------------------------------

   
         Selling, general and administrative expenses ("SG&A") were $17.3
million, $11.2 million, and $5.4 million in fiscal 1997, fiscal 1996 and fiscal

1995, respectively, representing increases of 54% in fiscal 1997 from fiscal
1996, and 106% in fiscal 1996 from fiscal 1995. SG&A as a percentage of revenue
was 153%, 70%, and 46% in fiscal 1997, fiscal 1996, and fiscal 1995,
respectively.
    

         The main component of the increase in SG&A in fiscal 1997 was marketing
and sales expenditures incurred in continuing support of the two new products
Cardia Salt Alternative and Wipe Out Dairy Wipes. The main component of the
increase in SG&A in fiscal 1996 was marketing and sales expenditures incurred in
the launch of these same two new products. SG&A costs principally representing
marketing personnel and promotional expenditures attributable to Cardia Salt
Alternative were $10.3 million and $3.1 million in fiscal 1997 and fiscal 1996,
respectively. SG&A costs largely representing marketing personnel and
promotional expenditures attributable to Wipe Out Dairy Wipes were $1.3 million
and $0.7 million in fiscal 1997 and fiscal 1996, respectively.

Research Expenses
- -----------------

         Research expenses were $4.8 million, $2.3 million, and $1.8 million in
fiscal 1997, fiscal 1996, and fiscal 1995, respectively, representing increases
of 111% in fiscal 1997 from fiscal 1996, and 25% in fiscal 1996 from fiscal
1995. Research expenses as a percentage of revenue were 43%, 14% and 16% in
fiscal 1997, 1996, and 1995, respectively. The increases in expenses in fiscal
1997 and fiscal 1996 were related to added spending to support ongoing programs.
Research spending in fiscal 1997 increased $1.7 million for pharmaceutical
products and $0.8 million for Cardia Salt Alternative. Research spending in
fiscal 1996 increased $0.5 million for pharmaceutical products.

Operating Loss/Income
- ---------------------

   
         The Company had an operating loss of $16.6 million in fiscal 1997,
compared with an operating loss of $4.6 million in fiscal 1996. This increase in
the loss was a result of increased expenditures in the areas of SG&A and
research referred to above and reduced revenue due primarily to the sale of A&B.
A&B contributed operating profits of $0.5 million and $3.4 million in fiscal
1997 and fiscal 1996, respectively.
    

         The Company had an operating loss of $4.6 million in fiscal 1996,
compared with operating income of $0.4 million in fiscal 1995. This loss was a
result of increased expenditures in the areas of SG&A and research referred to
above.

Sale of Aplin & Barrett
- -----------------------

         The Company completed the sale of its UK-based food preservative
business, Aplin & 



                                       17
<PAGE>

   
Barrett, Ltd. ("A&B"), to Burns Philp on December 12, 1996. Key terms of the
transaction included the payment to the Company of $13.5 million in cash and the
return of 2.42 million shares of the Company's common stock held by Burns Philp.
In addition, Burns Philp has provided the Company with a revolving line of
credit of up to $2.5 million that could be forgiven under certain circumstances
related to the performance of the food preservative business through June 30,
1999. The Company recorded a gain of $9.7 million in fiscal 1997 related to the
sale of A&B. See also Item 1 -- Business -- The Company.
    

Loss Before Tax Expense
- -----------------------

   
         The Company had a loss before tax expense of $6.7 million in fiscal
1997, compared with a loss of $4.4 million in fiscal 1996. The increase in the
loss was a result of increased expenditures in the areas of SG&A and research
referred to above and reduced revenue due to the sale of A&B. The loss was
partially offset by the $9.7 million gain on the sale of A&B.
    

         The loss before tax expense was $4.4 million in 1996, compared with
income before tax of $0.5 million in fiscal 1995. The loss was a result of the
Company's increased expenditures in the areas of SG&A and research referred to
above.

Tax Expense
- -----------

         The Company had a tax expense in fiscal 1997, despite having a loss
before tax expense, because of profits generated from its UK subsidiary prior to
the sale on December 12, 1996.

         Refer to Note 12 of the Notes to the Consolidated Financial Statements

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

         Revenues in the fourth quarter of fiscal 1997 were $0.8 million, a
decrease of $5.0 million or 86% from the corresponding quarter for the previous
year. The absence of A&B sales ($3.9 million in the fourth quarter of fiscal
1996), accounted for 78% of the decline, with decreases in Cardia Salt
Alternative, Wipe Out Dairy Wipes, and research payment revenues representing
the remainder.

   
         Operating losses for the quarter were $4.4 million, compared to a loss
of $2.3 million the previous fiscal year.
    


Quarterly Variations
- --------------------

         On a quarter-to-quarter basis, the Company's sales and income may vary
widely, as a result of various factors, including, for example, customers
placing orders in anticipation of a price increase and customers adjusting
finished goods inventory levels. As a result, the Company may report sales
increases or declines and/or income gains or losses for a particular quarter
that may not


                                       18
<PAGE>

reflect end-customer usage of the Company's products.

Liquidity and Capital Resources

         As of June 30, 1997, the Company had working capital of $7.1 million,
which included cash and cash equivalents of $8.6 million. On June 30, 1996,
working capital was $14.8 million, which included cash and cash equivalents of
$8.4 million.

         The Company raised $18.1 million during fiscal 1997 as a result of the
sale of Aplin & Barrett ($13.5 million) and the issuance of preferred stock
($4.2 million) and common stock ($0.4 million). $14.2 million was used in
operating activities, mainly to fund the operating loss of $15.6 million. $1.3
million was used in investing activities including $0.9 million for the purchase
of property and equipment and $0.4 million for patent costs and licensing fees.
An additional $2.5 million was used in financing activities representing the
redemption of the redeemable preferred ($1.5 million), repayments of capital
leases ($0.8 million) and cash used for the payment of preferred stock dividends
($0.2 million).

   
         As a result of the sale of A&B, the Company experienced a significant
decline in revenues during the latter part of fiscal 1997. This loss of revenues
also contributed to the increase in operating loss to $16.6 million in fiscal
1997, compared with an operating loss of $4.6 million in fiscal 1996. A&B
generated cash flows of $0.5 million and $3.1 million in fiscal 1997 and fiscal
1996, respectively. The sale of A&B did generate cash proceeds of $13.5 million
which provided adequately for the Company's short-term capital requirements
following the sale. The Company has only recently reinvested the proceeds from
this sale into the acquisition of Nutrition 21, which may replace the potential
to generate revenues. Nutrition 21 reported sales of $16,273,227 and net income
of $5,975,768 in 1996. However, there can be no assurance that the Nutrition 21
business and sales of the Company's other products will generate revenues, cash
flow, and earnings equal to those which would have come from A&B or that they
will be sufficient to make the Company's operations profitable.
    

         The Company anticipates a decline in research and SG&A expenditures as
it seeks to find pharmaceutical partners to fund research. In addition, the

Company is eliminating expenditures that are not critical to the process of
generating sales or meeting drug development milestones. The Company may report
operating income during the fiscal year ending June 30, 1998 as a result of the
aforementioned expense reduction combined with operating income provided from
the recent acquisition of Nutrition 21 in August 1997 (see Note 17, Notes to the
Consolidated Financial Statements for further explanation).

         The acquisition of Nutrition 21 was funded in part by a debt financing
of $3.3 million from State Street Bank & Trust ("SSBT"). The loans bear interest
at SSBT's prime rate plus one percent and are due February 1, 1998. The Company
does not have the funds to repay the loan and will be required to either extend
the payment terms to SSBT or refinance the debt. The Company is already in
discussions with SSBT and other financing institutions and expects to be 


                                       19
<PAGE>

able to either extend the terms or refinance the debt.

         In connection with the sale of A&B, BP provided the Company with a
revolving credit line of up to $2.5 million that could be forgiven under certain
circumstances related to the performance of the Nisaplin food preservative
business through June 30, 1999. Borrowings under this credit line will accrue
interest at a rate equal to the prime rate set from time to time by Citibank. To
date the Company has not borrowed any monies against this credit line nor is it
determinable at this time whether the future performance of the food
preservative business would result in a forgiveness.

         The Company's existing resources are expected to be sufficient to fund
the Company's foreseeable operations for the next 12 months. However,
acquisition activities and any increased research and development expenses over
the present level would require additional funds. Also, the Company is obligated
to repay the borrowings to SSBT. The Company intends to seek any necessary
additional funding through arrangements with corporate collaborators, through
public or private sales of its securities, including equity securities, or
through bank financing arrangements. The Company does not currently have any
specific arrangements for additional financing and there can be no assurance
that additional funding will be available at all or on reasonable terms.

Inflation and Prevailing Economic Conditions

         The Company does not believe inflation has had a significant impact on
the Company's operations.

         The Company does not believe exchange rates have had a significant
impact on the Company's operations.

Seasonality

         The Company does not believe there is any significant seasonal effect
on the Company's operations. There may be variations between quarters due to
other factors. See "Quarterly Variations."


Recently Issued Accounting Standards

         In February 1997, FASB issued SFAS No. 128, "Earnings Per Share" and
SFAS No. 129, "Disclosure of Information about Capital Structure." SFAS No. 128
specifies the computation, presentation, and disclosure requirements for
earnings per share (EPS) for entities with publicly held common stock or
potential common stock. SFAS No. 128 replaces the presentation of primary EPS
and fully diluted EPS with basic EPS and diluted EPS. It also requires dual
presentation of basic and diluted EPS on the face of the income statement for
all entities with complex capital structures and requires reconciliation of the
numerator and denominator of the basic EPS computation to the numerator and
denominator of the diluted EPS computation.



                                       20
<PAGE>

         SFAS No. 129 was issued in connection with SFAS No. 128 and specifies
the required disclosures about capital structure. Both SFAS No. 128 and No. 129
are effective for financial statements for both interim and annual periods
ending after December 31, 1997. It is not expected that the adoption of either
of these statements will have a material impact on the Company's financial
position or operating results.

Employment Agreements

         Effective September 1994, the Company entered into an employment
agreement with Fredric Price. The agreement provides for an annual salary of
$260,000 plus a performance related bonus. He was also granted options to
purchase up to a total of 500,000 shares of Common Stock, vesting in equal
installments over a five year period commencing at the conclusion of his first
year of employment. In addition, he was granted 15,325 shares of Common Stock on
the first anniversary of the agreement. A further 15,326 shares of Common Stock
were granted on the second anniversary of the agreement. Although employment is
at will, salary and certain benefits continue for twelve months after notice of
termination.

Stock Option Plans

         The Board of Directors has adopted and the shareholders have approved
four Stock Option Plans (the "Plan(s)"):

         1. The Incentive Stock Option Plan provides for the grant of qualified
incentive stock options to officers and key employees.

         2. The Non-qualified Stock Option Plan provides for the grant of
options to various persons who render certain services to the Company.

         3. The 1989 Stock Option Plan provides for the grant of options to
either group which, in the case of employees, may be incentive stock options.

         4. The 1991 Stock Option Plan provides for the grant of options to
either group which, in the case of employees, may be incentive stock options.

         Each of the Incentive and Non-qualified Stock Option Plans permits the
purchase of an aggregate of up to 250,000 shares of Common Stock. The 1989 Stock
Option Plan permits the purchase of an aggregate of up to 500,000 shares of
Common Stock. The 1991 Stock Option Plan permits the purchase of an aggregate of
up to 3,000,000 shares of Common Stock. The purpose of the Plans is to attract
and retain competent executive personnel and other key employees and consultants
and to provide incentives to all such persons to use their effort and skill for
the advancement and betterment of the Company by permitting them to participate
in the ownership of the Company.

         Options granted as qualified incentive stock options are intended to
qualify as Incentive Stock Options within the meaning of Section 422A of the
Internal Revenue Code of 1986, as amended. The exercise price of Incentive Stock
Options granted under the Plans shall not be less than the fair market value
(110% of the fair market value for 10% or greater shareholders) of the Common
Stock on the date of grant. Incentive Stock Options may not be exercised later
than ten years from the date of grant (five years for 10% or greater
shareholders). Determinations as to recipients of stock options under the Plans
and other terms of such grants are made by the Company's Board of Directors.

         The following tables set forth information as of June 30, 1997 with
regard to options granted (i) to the Company's Chief Executive Officer, and (ii)
to other officers of the Company named in the Summary Compensation Table.

Pension Plans

    AMBI Inc.
    ---------

         Eligible employees of the Company are entitled to participate in the
Burns Philp Inc. Retirement Plan for Non-Bargaining Unit Employees, a
non-contributory pension plan (the "Pension Plan") maintained by Burns Philp as
long as Burns Philp owns at least 20% of the Company's outstanding Common Stock.
Burns Philp currently holds approximately 40% of the Company's outstanding
Common Stock. Assuming retirement at age 65, the Pension Plan provides benefits
equal to the greater of (a) 1.1% of the employee's final average earnings

multiplied by the employee's final average earnings in excess of the average of
the contribution and the benefit basis in effect under Section 230 of the Social
Security Act for each year in the 35-year period ending with the year of Social
Security retirement age, multiplied by the employee's years of credited service
up to 35, minus any predecessor plan benefit in the case of an employee who
participated in a predecessor plan or (b) $24 multiplied by the number of years
of credited service up to 25 years plus $12 multiplied by the years of
employment from 26-40 years, minus any predecessor plan benefit in the case of
an employee who participated in a predecessor plan. The "final average earnings"
are the average monthly earnings during the five 


                                       30
<PAGE>

highest-paid consecutive calendar years within the last ten calendar years of
credited service with the Company. Earnings include the salary and bonus listed
in the summary compensation table. Earnings which may be considered under the
Pension Plan are limited to $160,000 per year subject to annual cost of living
adjustments as determined by the IRS.

         The following table sets forth estimated annual benefits payable upon
retirement, assuming retirement at age 65 in 1997 and a single life annuity
benefit, according to years of credited service and final average earnings. The
benefits listed are not subject to any deduction for Social Security or other
offset amounts.

         Peter Herring, Solomon Mowshowitz, Benjamin Sporn and Fredric Price
each have 1.5, 1.5, 5.0 and 2.75 years, respectively, of credited service under
the Pension Plan as of June 30, 1997, and, at age 65, would have approximately
21, 12, 10, and 17 years of credited service, respectively.


Compliance with Section 16(a) of the Securities Exchange Act of 1934

         Section 16(a) of the Securities Exchange Act of 1934 requires the
Company's officers and directors, and persons who own more than ten percent of a
registered class of the Company's equity securities, to file reports of
ownership and changes in ownership with the Securities and Exchange Commission.
Officers, directors and greater than ten-percent shareholders are required by
SEC regulation to furnish the Company with copies of all Section 16(a) forms
they file.

         Based solely on review of the copies of such forms furnished to the
Company, or written representations that no Forms 5 were required, the Company
believes that during the period from July 1, 1996 through June 30, 1997 all
Section 16(a) filing requirements applicable to its officers, directors and
greater than ten-percent beneficial owners were complied with.

Item 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         From 1989 through 1992, the Company issued an aggregate of 10,648,837
shares of Common Stock to BP in connection with various transactions. Pursuant
to an Agreement for the Purchase and Sale of Stock dated as of June 30, 1992
(the "Purchase Agreement"), in July 1993 the Company issued an additional
935,000 shares of Common Stock to BP. During July 1996, BP sold 1,400,000 shares
of Common Stock, and during December 1996 BP returned 2,420,000 shares of Common
Stock to the Company in connection with the purchase of A&B. As a result of the
July 1993 issuance, of prior acquisitions of shares of Common Stock, the July
1996 sale of Common Stock, and the December 1996 return of Common Stock, BP
currently owns 7,763,837 shares of Common Stock.

         Under the Purchase Agreement, the Company and BP entered into certain
arrangements and understandings which were effective until September 1, 1996
with respect to election of directors, the Chief Executive Officer, issuances of
securities, borrowings, and other corporate matters.

         On December 12, 1996, the Company completed the sale of its UK-based
subsidiary, A&B to BP in accordance with the terms of a Share Purchase Agreement
for $13.5 million in cash and the return to the Company of 2.42 million shares
of the Company's Common Stock held by BP. In addition, BP has provided the
Company with a revolving line of credit of up to $2.5 million. Any borrowings
under this line of credit can be forgiven under certain circumstances. As of the

                                       34
<PAGE>

date of filing this Form 10-K, no amount has been drawn under this line of
credit. In accordance with the Share Purchase Agreement, the purchase price was
paid in two installments: an initial payment of $8 million to the Company was
made on December 11, 1996; and a final payment of $5.5 million was made to the
Company on June 12, 1997.

         In connection with the transaction, the Company and A&B entered into
two License Agreements. Pursuant to the first License Agreement, the Company is
exclusively licensed by A&B for the use of nisin generally in pharmaceutical
products and animal healthcare products. Pursuant to the second License

Agreement, A&B is exclusively licensed by the Company generally for the use of
nisin as a food preservative and for food preservation. In addition, the Company
entered into a Supply Agreement with A&B pursuant to which A&B was required to
sell nisin to the Company while the Company was establishing its own source of
supply. The Company established its own source of supply for nisin, and sent
notice of termination of the Supply Agreement effective September 26, 1997.

         In connection with the transaction, the Company and BP entered into an
Investors' Rights Agreement pursuant to which BP agreed until December 11, 1998,
not to acquire, directly or indirectly, the Company's securities, and to refrain
from selling the Company's Common Stock, except under certain circumstances
through underwritten public offerings and private placement transactions. Until
December 11, 1998 and so long as BP owns at least 10% of the Company's
outstanding common stock, BP will vote its shares in favor of Fredric D. Price
and one nominee of Fredric D. Price for election to the Company's Board. So long
as BP owns at least 20% of the Company's outstanding common stock, BP is
entitled to nominate one member for election to the Company's Board.

         As of the date of sale, two of the Company's Board members were
representatives of BP. BP's Board representatives did not participate in the
vote of the Company's Board which approved the sale of A&B to BP. As a result of
the sale, BP's representation on Registrant's Board of Directors is reduced from
two members to one member. Colin Kop is currently serving as the Director
designated by BP. The amount of consideration for the sale was arrived at
through arms-length negotiation and a fairness opinion was obtained.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors and Stockholders
AMBI Inc.:

We have audited the consolidated financial statements of AMBI Inc. and
subsidiary as listed in the accompanying index. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of AMBI Inc., and
subsidiary as of June 30, 1997 and 1996, and the results of their operations and
their cash flows for each of the years in the three-year period ended June 30,
1997, in conformity with generally accepted accounting principles.

                            AMBI INC. AND SUBSIDIARY

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

1.       NATURE OF BUSINESS
         ------------------

         AMBI Inc. ('The Company') is a New York corporation which was
         incorporated on June 29, 1983. The Company develops and commercializes
         nutrition products for cardiovascular and other conditions and develops
         pharmaceuticals for serious infectious diseases. It markets the
         nutrition products through a network of distributors and should the
         pharmaceutical products be approved by a regulatory authority, it is
         anticipated that such products will be commercialized by joint venture
         partners.

         As of June 30, 1997, Burns Philp & Company Limited ("BP) owned
         7,763,837 shares of the Company's common stock, which constitutes
         approximately 40% of the issued and outstanding shares of common stock.
         BP is a leading global food manufacturer and marketer.

         The Company sold its UK-based food preservative business, Aplin &
         Barrett Limited ("A&B"), a wholly-owned UK company, to BP on December
         12, 1996. As a result, the operations of A&B are included in the
         financial statements through that date. A&B's principal activities are
         the manufacture and marketing of food preservatives, cheese starter
         cultures and other ingredients for the dairy industry.

         In October 1995, the Company acquired an exclusive license from a
         division of Orion Corporation ("Orion"), the largest pharmaceutical
         company in Finland, to sell Orion's patented salt alternative in the
         US. The Company began selling the salt alternative on a test basis in
         April 1996, and announced national availability in January 1997, under
         the trademark CardiaTM Salt Alternative.

         The Company has developed a moistened towel using a proprietary
         antibacterial formulation that is for use in preparing dairy cows for
         milking. The Company launched the product under its trademark Wipe
         OutTM Dairy Wipes on a test basis in February 1996, and nationally in
         April 1996.

         The Company signed an agreement with Nippon Shoji Kaisha, Ltd. (NSK) of
         Osaka, Japan in March 1996, in which NSK acquired the right to develop
         and market nisin, the Company's proprietary antibacterial peptide, in
         Japan and certain Asian countries for the treatment of
         hospital-acquired infections and infections of the colon. Under the
         agreement, NSK purchased $2 million of newly-issued common stock of the
         Company at $6.34 per share. In addition, NSK loaned $2 million to the
         Company that, under certain circumstances can be repaid in common stock
         valued at the market price at the time of repayment, and agreed to make
         research and milestone payments to the Company. Upon commercialization,
         NSK will pay royalties to the Company. The Company issued to NSK

         warrants to purchase 315,408 shares of the Company's common stock as
         part of this transaction.

         On August 12, 1997 the Company completed the acquisition of Nutrition
         21, a privately-owned San Diego, California-based company engaged in
         the development and marketing of proprietary nutrition products and
         dietary supplements. See Note 18 -- Subsequent Events.

   
         During fiscal 1997, the Company incurred a $16.6 million loss from
         operations. As more fully discussed in note 18, the Company acquired
         Nutrition 21 for $10.0 million and other considerations. The
         transaction was financed from the Company's operating funds and a $3.3
         million loan from State Street Bank and Trust Company ("State Street
         Bank") that matures in February 1998. Management believes that the
         acquisition of Nutrition 21 and expense reductions will result in a
         significant reduction in the operating loss for fiscal 1998. Management
         also believes that it will be able to extend the loan from State Street
         Bank upon maturity or obtain other financing to satisfy this
         obligation. The achievement of a significant reduction in the operating
         loss and the refinancing the State Street Bank loan will be significant
         factors in the Company's ability to maintain adequate levels of cash
         flow.

2.       SIGNIFICANT ACCOUNTING POLICIES

         Significant accounting policies followed by the Company are in
accordance with generally accepted accounting principles and are as follows:

         a)       Consolidation

                  The consolidated financial statements include the results of
                  operations and financial position of the Company and its
                  wholly owned subsidiary, A&B, after elimination of material
                  inter-company accounts and transactions.

         b)       Cash Equivalents

                  The Company considers all highly liquid debt instruments with
                  original maturities of three months or less to be cash
                  equivalents. Cash equivalents included in the accompanying
                  financial statements include money market accounts.

         c)       Inventories


                  Inventories are valued at the lower of cost (first-in,
                  first-out) or market value, and consist of:

                                                        1997           1996

         d)       Property and Equipment

                  Property and equipment are stated at cost. Depreciation is
                  provided using the straight-line method to depreciate assets
                  over their estimated useful lives. The estimated useful lives
                  are as follows:

                             Buildings and building
                               improvements              -    50 years
                             Furniture and fixtures      -    20 years
                             Machinery and equipment     -    5 or 10 years
                             Office equipment            -    3, 5 or 6 years
                             Motor vehicles              -    5 years
                             Leased assets               -    3 or 5 years

         e)       Patent Costs and Licensed Technology

                  Patent costs and licensed technology have been capitalized and
                  are being amortized on a straight-line basis over periods
                  ranging from one to fifteen years.

         f)       Research and Development

                  Research and development costs are expensed as incurred.

2.       SIGNIFICANT ACCOUNTING POLICIES (Continued)

         g)       Net (Loss)/Earnings Per Share

                  Earnings per share for the years ended June 30, 1995 are
                  computed based on the weighted average number of shares
                  actually outstanding plus the shares that would be outstanding
                  assuming the exercise of dilutive stock options, all of which
                  are considered to be common stock equivalents. The number of

                  shares that would be issued from the exercise of stock options
                  and warrants has been reduced by the number of shares that
                  could have been purchased from the proceeds at the average
                  market price of the Company's stock.

                  Common stock equivalents are not included in the computation
                  of average shares outstanding for the year ended June 30, 1997
                  and June 30, 1996, because the effect of such inclusion would
                  be to decrease the loss per share.

</TABLE>

                  In accordance with the March 1997 SEC Staff announcement, the
                  conversion discount on the Company's preferred stock has been
                  recognized as additional preferred dividends. The conversion
                  discount on preferred stock in the table above represents the
                  amortized discount of $173,000 on the Series D preferred stock
                  in fiscal 1997 and the conversion discount of $1,343,000 on
                  the Series C preferred stock in fiscal 1996. See Note 8.

         h)       Foreign Currencies

                  Transactions in currencies other than the local currency are
                  recorded at the rate at the date of the transaction. Balances
                  denominated in currencies other than the local currency are
                  translated at the exchange rate at the balance sheet date.

                  Assets and liabilities of the Company's foreign subsidiary are
                  generally translated at current rates, and related translation
                  adjustments are reported as a component of stockholders'
                  equity. Statement of operations accounts are translated at the

                  average rates of exchange reported during the year.
                  Stockholders' equity amounts are translated at historical
                  rates, and variances from the balance sheet rate are recorded
                  as currency translation adjustment.

         i)       Taxation The Company accounts for deferred taxes using the
                  liability method.

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

4.       CAPITAL LEASES

         On December 11, 1996, concurrent with the sale of A&B to BP, the
         Company bought out the leases for certain lab and office equipment that
         were entered into in 1995. Subsequently, on December 30, 1996, the
         Company entered into an agreement to lease certain lab equipment. The
         terms of the lease met the criteria for capitalization under the
         Financial Accounting Standards (FAS) No. 13, "Accounting for Leases."
         Accordingly, the lease has been classified as a capital lease in the
         accompanying financial statements. The following is a schedule by years
         of future minimum lease payments under the capital lease together with

         the present value of the net minimum lease payments.

          Year ending June 30:                                      $ 000
                                                                     -----

                                                                      ----
                  Total minimum lease payments                         351

                  Present value of net minimum lease payments          311

         This obligation is reflected in the balance sheet at June 30, 1997, as
         current and non-current obligations of $127,000 and $184,000,
         respectively.

5.       NOTES PAYABLE

         In connection with the purchase of a telephone system, the Company
         borrowed approximately $35,000 in November 1995. This loan bears
         interest at a rate of 6% and matures in November 1999. The payments on
         the loan approximate $800 per month.

         As a result of the sale of A&B to BP the Company has access to a
         revolving line of credit of up to $2.5 million that could be forgiven
         under certain circumstances related to the performance of the food
         preservative business through June 30, 1999. The loan bears an interest
         rate equal to the Citibank prime rate. As of July 25, 1997, the Company
         has not borrowed any funds on this line of credit.

6.       LONG TERM DEBT

         In March 1996, as part of a research collaboration with Nippon Shoji
         Kaisha of Japan, the Company has secured a loan of $2 million. This
         loan bears interest at a rate of 5%, and matures in March 1999.
         Interest is payable quarterly and principal payment is due in full upon
         maturity.

8.       PREFERRED STOCK

         The Company is authorized to issue up to 5,000,000 shares of preferred
         stock, with a $0.01 par value, in one or more series and to fix the
         powers, designations, preferences and rights of each series.

         In May 1997, the Company issued 45,000 shares of non-voting, Series D
         preferred stock. Each share of D Preferred has a face value of $100 per
         share, and accrues a premium at 6% per annum for conversion purposes.
         The D Preferred is not convertible during the 90-day period from May 8,
         1997 until August 5, 1997. For the next 90 days until November 4, 1997,
         the D Preferred is convertible by the holder into Common Stock at
         $2.49557 per share, which is 110% of the average closing bid price for
         the 10 trading days prior to May 8, 1997. After November 4, 1997 the
         conversion price per share is the lesser of (i) $2.49557 or (ii) the
         average closing bid price of the Common Stock for the ten trading days
         prior to conversion less a discount which increases in stages from 13%
         on November 4, 1997 to 25% by August 1, 1998. The Company has
         registered the Common Stock issuable upon conversion. In connection
         with this private placement, the Company also issued Warrants to
         purchase 528,937 shares of Common Stock at $2.72 per share.

         In October 1995, the Company issued 895 shares of non-voting, Series C
         preferred stock for $10,000 per share. These shares are convertible
         into common stock of the Company at the lower of $3.25 per share or 85%
         of the average closing bid price for the common stock of the Company
         for the five trading days immediately preceding the date of conversion,
         and bear an 8% dividend payable in common stock of the Company on the
         same basis as the preferred stock at the time of conversion. The
         Company has the right to redeem the preferred stock for cash upon
         receipt of a notice of conversion. All preferred stock outstanding on
         October 13, 1999 will automatically convert into common stock of the
         Company. As of June 30, 1997, there were 222 shares of the preferred
         stock outstanding.

         Dividends payable at June 30, 1997 were approximately $340,000.

         All of the outstanding issue of 1,500 shares of redeemable preferred
         stock at June 30, 1996 was redeemed on June 12, 1997 and all cumulative
         annual dividends were paid at that time.

         At June 30, 1997, 2,170,401 shares were issuable upon exercise of the
         above warrants. All such warrants were available to be exercised
         immediately. The warrants expire between 1997 and 2004. Certain of the
         warrants include anti-dilution clauses.

         On April 10, 1986, the Company adopted a Nonqualified Stock Option Plan
         whereby options to purchase 250,000 shares of the Company's common
         stock may be granted to consultants and Business Advisory Board and
         Scientific Advisory Board members.

         The Company adopted three Incentive Stock Option Plans ('Incentive
         Plans') whereby options to purchase an aggregate of 3,750,000 shares of
         the Company's common stock may be granted to officers, directors,
         employees, consultants and others who render services to the Company.
         The exercise price per share for the options granted under the
         Incentive Plans may not be less than the fair value of the Company's
         common stock on the date of grant. The options expire between 1997 and
         2007.

         Each of these options are entitled to one share of common stock, and
         908,796 of these options are exercisable at June 30, 1997.

10.      STOCK-BASED COMPENSATION

         The per share weighted-average fair value of stock options granted
         during fiscal 1997 and 1996 was $2.43 and $2.22, respectively on the
         date of grant using the Black Scholes option-pricing model with the
         following weighted-average assumptions: expected dividend yield of 0%,
         risk free interest rate of 6%, expected stock volatility of 81%, and an
         expected option life of 5 years.

         The Company applies APB Opinion No. 25 in accounting for its Plan and,
         accordingly, no compensation cost has been recognized in the financial
         statements for its stock options which have an exercise price equal to

         the fair value of the stock on the date of the grant. 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 income
         would have been reduced to the pro forma amounts indicated below:

                                                         1997           1996

10.      STOCK-BASED COMPENSATION (Continued)

         Pro forma net income reflects only options granted in fiscal 1997 and
         1996. Therefore, the full impact of calculating compensation cost for
         the stock options under SFAS No. 123 is not reflected in the pro forma
         net income amounts presented above because compensation cost is
         reflected over the option's vesting period of 5 years and compensation
         cost for options granted prior to July 1, 1995.

16.      PENSION BENEFITS

         The Company participates in a defined benefit pension plan of Burns
         Philp Inc., an affiliated company, and the plan is called the 'Burns
         Philp Inc. Retirement Plan for Non-Bargaining Unit Employees'. This
         plan provides retirement benefits based upon years of service, or a
         combination of employee compensation and years of service.
         Contributions payable to the plan were approximately $67,000 in 1997,

         $42,000 in 1996 and $28,000 in 1995.

         A&B participated in a defined benefit pension plan of Burns Philp (UK)
         plc, an affiliated company called "The Burns Philp (K) plc Pension
         Plan." The funding status of the Burns Philp (UK) Plc Pension Plan for
         the A&B employees as of June 30, 1996 is shown below. Since the sale of
         A&B was completed December 12, 1996, figures as of June 30, 1997 are
         not relevant.

                  $383,000 relates to A&B as determined by actuarial valuation,
                  and is therefore included in the accounts of the Company.

                  Of the above net pension costs of $280,000 at June 30, 1996,
                  $181,000 relates to A&B as determined by actuarial valuation,
                  and is therefore included in the accounts of the Company. For
                  fiscal 1995 all of the pension cost relate to A&B. The pension
                  cost for the period July 1, 1996 through December 12, 1996
                  (date of sale of A&B) was approximately $88,000. The
                  components of this pension cost is not available.

                  Assumptions used in accounting for the pension plan as at
                  June 30, 1996 and 1995 were:

                                            1996 1995
                                               %    %
                                              --   --

                  Discount rate                8    9
                  Rates of increase in
                   compensation levels         7    7
                  Expected return on assets   10   10

17.      RISKS AND UNCERTAINTIES

         The Company buys certain of its inventories from single suppliers.
         Management believes that other suppliers could provide similar products
         at comparable terms. As a result, management believes a change in
         suppliers would not disrupt on-going operations and would not effect
         operating results adversely.

18.      SUBSEQUENT EVENTS

         On August 12, 1997, the Company completed the acquisition of Nutrition
         21, a privately-owned San Diego, California-based company engaged in
         the development and marketing of proprietary nutrition products and
         dietary supplements. Terms of the transaction included the payment by
         the Company of $10 million in cash and 500,000 shares of the Company's
         common stock. The purchase agreement also provides for annual
         contingent future payments for each of the next four years of $2.5
         million adjusted for the achievement of certain sales levels, and
         royalties of 2.5% to 5% of net sales of products recommended for
         certain patented uses. The acquisition was financed in part by a six
         month loan of $3.3 million from State Street Bank bearing an interest
         rate of prime plus 1%. As part of the same financing from State Street
         Bank and Trust, the Company secured a revolving credit facility of $4.0
         million which matures February 1, 1998 and is renewable for up to 18
         months, at the lender's option. The facility bears an interest rate of
         prime plus 1%.

19.      RECENTLY ISSUED ACCOUNTING STANDARDS

         In February 1997, FASB issued SFAS No. 128, "Earnings Per Share" and
         SFAS No. 129, "Disclosure of Information about Capital Structure." SFAS
         No. 128 specifies the computation, presentation, and disclosure
         requirements for earnings per share (EPS) for entities with publicly
         held common stock or potential common stock. SFAS No. 128 replaces the
         presentation of primary EPS and fully diluted EPS with basic EPS and
         diluted EPS. It also requires dual presentation of basic and diluted
         EPS on the face of the income statement for all entities with complex
         capital structures and requires reconciliation of the numerator and
         denominator of the basic EPS computation to the numerator and
         denominator of the diluted EPS computation.

         SFAS No. 129 was issued in connection with SFAS No. 128 and specifies
         the required disclosures about capital structure. Both SFAS No. 128 and
         No. 129 are effective for financial statements for both interim and
         annual periods ending after December 31, 1997. It is not expected that
         the adoption of either of these statements will have a material impact
         on the Company's financial position or operating results.

         In June 1997, FASB issued SFAS No. 130, "Reporting Comprehensive
         Income" and SFAS No.131, "Disclosures about Segments of an Enterprise
         and Related Information." SFAS No. 130 establishes standards for
         reporting and display of comprehensive income and its components in a
         full set of general purpose financial statements. SFAS No. 131
         supersedes SFAS No. 14, "Financial Reporting for Segments of a Business
         Enterprise," but retains the requirement to report information about
         major customers. Both SFAS No. 130 and No. 131 are effective for
         financial statements for both interim and annual periods ending after
         December 31, 1997. It is not expected that the adoption of either of
         these statements will have a material impact on the Company's financial
         position or operating results.
