Note 1   BASIS OF PRESENTATION
         ---------------------

         The accompanying unaudited interim consolidated financial statements
         have been prepared in accordance with generally accepted accounting
         principles for interim financial statement reporting and in accordance
         with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X.
         Accordingly, they do not include all the information and footnotes
         required by generally accepted accounting principles for complete
         financial statements. In the opinion of management, all adjustments
         (consisting of normal recurring accruals) considered necessary for a
         fair presentation have been included. Operating results for the three
         month period ended September 30, l998 are not necessarily indicative of
         the results that may be expected for the fiscal year ending June 30,
         l999. For further information, refer to the consolidated financial
         statements and notes thereto, included in the Company's annual report
         on Form 10-K as amended for the year ended June 30, l998.

         Certain reclassifications have been made to the prior period's
         financial statement amounts to conform to the current period
         presentation.


Note 2   ACQUISITION OF NUTRITION 21
         ---------------------------

         The purchase price for the acquisition of Nutrition 21 was $10,000,000
         in cash plus 500,000 restricted shares of common stock of the Company.
         The Purchase Agreement also provides for annual contingent payments for
         each of the next four years of $2.5 million, but subject to adjustment
         for the achievement of net sales levels of certain products (contingent
         consideration clause), and royalties of 2.5% to 5.0% on net sales of
         products recommended for certain patented uses. At September 30, l998,
         the Company recorded on its balance sheet a then current liability of
         $275 in respect of a contingent payment due in September 1999 to the
         former owners of Nutrition 21 as provided for in the acquisition
         agreement. On September 30, l998, the Company paid the former owners of
         Nutrition 21 approximately $3.3 million representing the full amount of
         the contingent payment due for the 12 month period September 1997
         through August 1998.

         The following represents the pro forma consolidated results of
         operations as if the Company and Nutrition 21 had been combined for the
         three months ended September 30, 1997. The pro forma results of
         operations reflect amounts adjusted to their accounting basis as if the
         acquisition had occurred at the beginning of the respective periods.
         The pro forma information is not necessarily indicative of the results
         of operations as they may be in the future or as they would have been
         had the acquisition been effected on the assumed dates. The pro forma
         information for the three months ended September 30, 1997 is as
         follows:


                           Net sales                                   $4,566

         During the quarter ended September 30, l998, and the fiscal year ended
         June 30, 1998, the Company did not deduct any amounts from the
         inventory valuation reserve.


Note 4   STOCKHOLDERS' EQUITY
         --------------------

         Convertible 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 (the "D Preferred"). 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 Company has registered 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. At September 30, 1998, there were 15,250 shares of D
         Preferred outstanding.

         With respect to the D Preferred, on December 5, 1997 the holders of the
         D Preferred (the "D Investors") converted fifty percent of their
         holdings into common stock of the Company at a twenty-five percent
         discount to the average closing bid prices for the Company's Common
         Stock for the five (5) consecutive trading days immediately preceding
         conversion. The Company reduced both the fixed conversion price of
         $2.49557 and the warrant exercise price of $2.72 to $2.25. The maturity
         date for mandatory conversion was extended to May 8, 2001. The D
         Investors agreed not to convert any of their remaining holdings for a
         period of six months ending on June 5, 1998. The twenty-five percent
         conversion discount described above has been recorded as additional
         preferred dividends and reduced net income available to common
         stockholders for the year ended June 30, 1998.

         In October 1995, the Company issued 895 shares of non-voting, Series C
         Preferred Stock (the "C Preferred") 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 C Preferred outstanding on
         October 13, 1999 will automatically convert into common stock of the
         Company. As of September 30, 1998, there were 222 shares of C Preferred
         outstanding.

Note 4   STOCKHOLDERS' EQUITY, Continued
         -------------------------------

         With respect to the C Preferred, on December 5, 1997, the Company
         reduced the fixed conversion price from $3.25 to $2.75. The maturity
         date for mandatory conversion was extended to October 13, 1999. The
         holders of the C Preferred agreed not to convert any of their remaining
         holdings for a period of six months ending on June 5, 1998.

         Dividends payable on the C Preferred and the D Preferred were
         approximately $654 and $637 at September 30, 1998 and June 30, l998,
         respectively.

         The reduction in the fixed conversion price described above for the
         Series C and Series D Preferred Stock has not been recorded as
         additional preferred dividends for the year ended June 30, 1998 and the
         three months ended September 30, l998 because the Company's stock price
         is not high enough for the fixed conversion price to be beneficial to
         the Series C and Series D investors. As of June 30, 1998 and September
         30, l998, the original discounts of fifteen and twenty-five percent
         granted to the Series C and Series D investors, respectively, are more
         beneficial for conversion purposes. As such, these conversion discounts
         have been recorded as additional preferred dividends. Should the fixed
         conversion price become more beneficial to the Series C investors (when
         the Company's stock price exceeds $3.23) or the D Investors (when the
         Company's stock price exceeds $3.00), the Company will record
         additional preferred dividends based on the Company's stock price at
         that time.

Item 2   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

         Historically, the Company's revenues have been attributable primarily
         to sales of its own products. Since the acquisition of Nutrition 21 on
         August 11, l997, the Company's revenues have been primarily derived
         from the sale of nutrition products to manufacturers of vitamin and
         mineral supplements and to a lesser extent from the sale of Wipe
         Out(TM) Dairy Wipes and Cardia(R) Salt. The Company has also received
         royalty income from users of its patented technology and milestone
         payments from research partners.

         Cost of goods sold 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
         acquisition-related goodwill and intangible assets, and amortizes them
         over periods of one to twenty years.

         On August 11, l997, 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 in cash plus 500,000 restricted shares of
         Common Stock of the Company, and additional cash payments which are
         contingent upon the achievement of certain sales level in the four
         years following acquisition. The Company will also pay royalties to the
         sellers on sales of certain patented products. Of the $10 million cash
         paid at closing, $3.3 million was provided pursuant to a Loan Agreement
         with State Street Bank and Trust Company ("SSBT") and the remainder
         came from internal working capital. The loan bears interest at SSBT's
         prime rate plus one percent and is due June 30, 2000.

         The acquisition of Nutrition 21 was accounted for under the purchase
         method. Based upon the allocation of purchase price, the transaction
         resulted in $10.7 million of identifiable intangible assets, primarily
         patents and trademarks, and $1.0 million of goodwill. These amounts
         include approximately $2.5 million of identifiable intangible assets
         and $0.2 million of goodwill recorded in connection with amounts due
         under a contingency consideration clause in the Nutrition 21 purchase
         agreement. As additional contingency consideration is earned, the
         Company will allocate these amounts in accordance with the original
         purchase price allocation. The Company is amortizing the goodwill over
         15 years and amortizing the identifiable intangible assets over their
         useful economic lives, which range from three to 15 years.


         Results of Operations

         The Company has an accumulated deficit due primarily to historical
         operating losses, 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, l993).

Item 2   Management's Discussion and Analysis of Financial Condition and
         Results of Operations, Continued


         Net Sales
         ---------

         Net sales increased 86% to $5,815 for the quarter ended September 30,
         l998 from $3,118 for the quarter ended September 30, l997. The increase
         in net sales of $2,697 is attributable to the acquisition of Nutrition
         21 which generated $5,504 for the quarter ended September 30, l998 as
         compared to net sales of $2.5 million for the quarter ended September
         30, l997. N21 was acquired by the Company on August 11, l997 and
         therefore the quarter ended September 30, l997 includes Nutrition 21
         from the acquisition date until the end of the quarter. Net sales of
         other products decreased in the quarter ended September 30, l998 from
         the quarter ended September 30, l997 by a net amount of $200 primarily
         due to a change in marketing and distribution strategy for Cardia Salt.

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

         Gross profit for the Company as a percentage of net revenues was 88%
         for the quarter ended September 30, l998, compared to 80% for the
         quarter ended September 30, 1997. This increase in gross profit
         reflects a sales mix which includes the higher margin Nutrition 21
         products for the quarter ended September 30, l998, compared to a sales
         mix which included the Company's lower margin products for the quarter
         ended September 30, l997. Nutrition 21 products had a gross profit
         percentage of approximately 92% for the quarter ended September 30,
         1998 and September 30, 1997 while other products had a gross profit
         percentage of approximately 28% for the quarter ended September 30,
         1998 and September 30, 1997.

         Selling, General and Administrative Expenses (SG&A)
         ---------------------------------------------------

         SG&A expenses decreased $45 or 2% for the quarter ended September 30,
         1998 as compared to the quarter ended September 30, 1997. The decrease
         is primarily due to lower marketing costs for Cardia(R) Salt, offset by
         the addition of Nutrition 21 for the full quarter ended September 30,
         1998.

         Research and Development Expenses
         ---------------------------------

         Research costs decreased slightly for the quarter ended September 30,
         l998, compared to the quarter ended September 30, 1997. This decrease
         is due to the Company's decision to reduce research activities related
         to the infectious disease drug business.

         Operating Income/(Loss)
         -----------------------

         The Company's reported operating income of $1,478 for the quarter ended
         September 30, 1998 compared to a loss of $862 for the quarter ended
         September 30, l997. The increase in revenue and profitability of the
         company was due to the increase in gross profit attributable to the
         acquisition of Nutrition 21 and its product lines.

         Interest Expense, Net
         ---------------------

         Interest expense, net of interest income, was $54 in the quarter ended
         September 30, l998 compared to interest income of $20 in the
         corresponding period in 1997. Interest expense increased for the
         quarter ended September 30, 1998 as compared to the same period during
         the prior fiscal year because the loan from SSBT was outstanding for
         the period August 11, 1997 through September 30, 1997 during the prior
         year and the loan was outstanding for the entire three months ended
         September 30, 1998.

Item 2   Management's Discussion and Analysis of Financial Condition and
         Results of Operations, Continued


         Other Income, Net
         -----------------

         In conjunction with the relocation of the Company's headquarters
         operations in September 1998 to Purchase, NY, the Company received $404
         when it vacated the prior premises. The Company is utilizing $361 of
         those funds to pay the costs associated with the relocation. The
         decrease in Other Income, Net arises primarily from a reduction in
         sponsored pharmaceutical-related research.

         Income Tax Expense
         ------------------

         Income tax expense increased from $7 for the quarter ended September
         30, l997 to $91 for the quarter ended September 30, l998 primarily due
         to estimated federal alternative minimum tax and state taxes.

         Net Income/Loss and Earnings Per Share
         --------------------------------------

         Net income for the quarter ended September 30, l998 was $1,412 as
         compared to a net loss for the quarter ended September 30, l997 of
         $724. Basic and diluted earnings per share for the quarter ended
         September 30, l998 were $0.06 and $0.05, respectively, as compared to a
         basic and diluted loss per share of ($0.06) for the quarter ended
         September 30, l997. This increase in net income and the resulting
         earnings per share increase resulted from the acquisition by Nutrition
         21 and its product lines.

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

         Liquidity and Capital Resources

         As of September 30, l998, the Company had a working capital deficit of
         $1.6 million. Cash and cash equivalents were $322. The Company
         continues to take steps to improve its working capital position by
         increasing sales from existing businesses and reducing operating
         expenses. With the closing of the AHP transaction (discussed below),
         the Company has restored a working capital surplus. On June 30, l998,
         the Company had a working capital deficit of $2.3 million, which
         included cash and cash equivalents of $2.1 million.

         On September 17, l998, the Company entered into agreements to form a
         strategic alliance with American Home Products Corporation ("AHP") for
         retail distribution of the Company's proprietary nutrition products. As
         part of the alliance, Whitehall-Robins Healthcare Division was granted
         an exclusive license to sell the Company's Cardia(R) Salt Alternative
         in retail markets in the United States and received a first negotiation
         option for exclusive rights and licenses for additional nutrition
         products for retail distribution in the United States. In addition, AHP
         agreed to make equity investments in newly issued shares of the
         Company's common stock. The alliance became effective on October 8,
         l998, when AHP paid $1.15 per share, or a total of $4.0 million, for
         3,478,261 shares of newly issued common stock. Also on October 8, l998,
         the Company received an upfront payment of $1.0 million from AHP for
         the rights and options granted under the agreement. The Company
         retained the exclusive rights to market its products in both direct
         response and ingredient channels. Until used in the Company's
         operations, the Company will invest the AHP proceeds in investment
         grade commercial paper or equivalent instruments.

Item 2   Management's Discussion and Analysis of Financial Condition and
         Results of Operations, Continued


         As of September 30, l998, the Company had a term loan balance of $2.2
         million with SSBT. The Company had originally borrowed $3.3 million
         from SSBT to fund the acquisition of Nutrition 21. At December 31,
         1997, the Company refinanced the then existing $2.8 million balance of
         the loan. Under the revised terms the Company received a $2.8 million
         term loan which is being amortized through monthly payments of
         principal and interest over a 30 month period at an interest rate equal
         to the prime rate plus one percent. SSBT also continues to provide a
         revolving credit line, based upon the level of inventory and
         receivables, of up to $4.0 million. All amounts owing under the term
         loan and the revolving credit line are due by June 30, 2000, the
         expiration date of the credit line. The Company had a zero balance
         under the revolving credit line at September 30, 1998.

         On December 12, 1996, the Company completed the sale of its UK-based
         food preservative business, Aplin & Barrett Ltd. ("A&B") to Burns Philp
         & Company Ltd. ("Burns Philp"). The Company reinvested the proceeds
         from the sale of A&B into the acquisition of Nutrition 21, which has
         thus far generated revenues greater than those lost as a result of the
         sale of A&B. In connection with the sale of A&B, Burns Philp 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 food preservative business through June 30, l999.
         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 amounts under this credit line, nor is it
         determinable at this time whether the future performance of the food
         preservative business would result in the forgiveness of any debt.

         With respect to the acquisition of Nutrition 21, at September 30, l998,
         the Company recorded on its balance sheet a then current liability of
         $275 in respect of a contingent payment due in September 1999 to the
         former owners of Nutrition 21 as provided for in the acquisition
         agreement. On September 30, l998, the Company paid the former owners of
         Nutrition 21 approximately $3.3 million representing the full amount of
         the contingent payment due for the 12 month period September 1997
         through August 1998. The Company utilized cash generated from
         operations to satisfy the contingent payment obligation.

         In March 1996, the Company entered into an agreement with AZWELL, Inc.
         (formerly Nippon Shoji Kaisha), under which AZWELL agreed to provide
         research funding and equity and debt financing in return for exclusive
         rights to certain nisin based drug products in Japan and certain other
         Asian countries. In conjunction with that Agreement, AZWELL 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. The Company has
         advised AZWELL that one milestone, FDA acceptance of its
         Investigational New Drug application for diseases of the colon, has
         been met and as a result, the Company intends to repay $1 million of
         the loan with its Common Stock and $1 million in cash from operating
         activities. The loan is payable in full in March 1999.

         The Company's primary sources of financing are cash generated from
         continuing operations and the SSBT revolving line of credit. The
         availability under the SSBT revolving line of credit is based on the
         Company's accounts receivable and inventory. At September 30, l998, the
         Company had a zero balance under this line. The Company believes that
         cash generated from operations and cash available under the line of
         credit will provide sufficient liquidity to fund operations. The
         Company continues to eliminate expenditures that are not critical to
         the process of generating sales.

Item 2   Management's Discussion and Analysis of Financial Condition and
         Results of Operations, Continued


         Future acquisition activities and any increases in research and
         development expenses over the present level may require additional
         funds. Also, the Company is obligated to repay the borrowings to SSBT
         in June 2000. 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.

         Year 2000
         ---------

         The Company is analyzing the nature and extent of work required to make
         its products, systems and infrastructure Year 2000 compliant. The
         Company uses a number of computer software programs and operating
         systems in its internal operations, including applications in financial
         business systems, product development, marketing and various other
         administrative functions. To the extent that these software
         applications contain source code that is unable to appropriately
         interpret the upcoming year "2000", some level of modification or
         possibly replacement of such applications may be necessary. The Company
         is also asking its suppliers to determine whether there are any Year
         2000 problems which could affect the Company, and to provide assurances
         that they will not permit a Year 2000 problem to interfere with
         performance under agreements with the Company. To the extent that the
         Company is uncertain as to its suppliers compliance, it may choose to
         increase certain key product inventories during 1999 to assure
         continuity of operations. The Company continues to evaluate the
         estimated costs associated with its Year 2000 compliance efforts. While
         these efforts involve some additional costs, the Company believes,
         based on available information, that it will be able to manage it total
         Year 2000 transition without material adverse effect on its business,
         financial condition, or operating results.

         Recently Issued Accounting Standards
         ------------------------------------

         In June 1997, the Financial Accounting Standards Board (FASB) issued
         Statement of Financial Accounting Standards (SFAS) No. 131 "Disclosures
         about Segments of an Enterprise and Related Information." 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. This statement is effective for financial statements
         for annual periods beginning after December 15, l997.

         In June 1998, the FASB issued SFAS No. 133 "Accounting for Derivative
         Instruments and Hedging Activities," SFAS No. 133 requires companies to
         recognize all derivatives as assets or liabilities measured at their
         fair value. Gains or losses resulting from changes in the values of
         those derivatives would be accounted for depending on the use of the
         derivative and whether it qualifies for hedge accounting.

         It is not expected that adoption of these statements will have a
         material impact on the Company's financial position or operating
         results.

Item 1 - Legal Proceedings


The Company was a defendant in a lawsuit brought in 1997 in the United States
District Court for the Southern District of New York (Civil Action No. 97
Civ.5802 (BDP)) by RCN Products, Inc. ("RCN"). RCN sued under the Lanham Act and
New York General Business Law, alleging that the term "Salt Alternative" used by
AMBI to describe its Cardia(R) product, amounts to unfair competition by leading
consumers to believe that the Cardia product is salt free. Effective November 9,
1998, the Company and RCN settled the lawsuit.

Exhibit 10.58

Certain portions of this Exhibit have been filed separately with the
Commission and are subject to a request for confidential treatment.

                          STOCK PURCHASE AGREEMENT

         AGREEMENT FOR THE PURCHASE AND SALE OF STOCK dated as of September
17, 1998, by and between AMBI INC., a New York corporation ("AMBI"), and
AMERICAN HOME PRODUCTS CORPORATION, a Delaware corporation ("AHP").

                            PRELIMINARY STATEMENT

         The parties are concurrently herewith entering into a License, Option 
and Marketing Agreement dated the date hereof (the "Product Agreement"). The 
terms "Effective Date," "HSR Act," "Product," "Option Product," and "Additional
Product" shall have the meanings attributed thereto in the Product Agreement.

         The parties wish to provide for certain purchases by AHP of common
stock of AMBI ("common stock") and for certain agreements in connection
therewith.

         NOW, THEREFORE, in consideration of the premises and the
representations, warranties, covenants and agreements herein contained, the
parties hereto agree as follows:

1.   Purchases and Sales of AMBI Stock

     1.1. Base Purchase.

         1.1.1.     At a closing (the "Base Closing") to occur on September 24,
               1998, or, if a filing is required to be made under the HSR
               Act or rules, within five business days after any applicable
               waiting periods under the HSR Act or rules shall have
               terminated or expired, AHP shall purchase from AMBI, and AMBI
               shall issue to AHP, 3,478,261 shares of common stock (the
               "Base Shares").

         1.1.2.     The purchase price for the Base Shares shall be $4,000,000,
               and shall be paid by AHP at the Base Closing by wire transfer
               against the delivery by AMBI to AHP of the certificates which
               represent the Base Shares and the opinion of AMBI's counsel
               to the effect that the Base Shares are duly authorized,
               validly issued, fully paid and nonassessable, and free and
               clear from any liens or encumbrances of any kind (except
               restrictions from transfer as set forth in applicable
               securities laws).


<PAGE>

         1.1.3.     The Base Closing shall occur at the offices of AMBI. At such
               Closing, each of AMBI and AHP shall deliver to the other
               party, a certificate by an officer of each company (whose
               incumbency is verified by the Corporate Secretary or an
               Assistant Secretary) certifying that each of the
               representations and warranties (other than with respect to
               the number of shares issued and outstanding in the
               capitalization) are true and correct as of the date of such
               Closing and that all covenants required to be performed in
               this Agreement have been performed in all material respects
               by each such party.

     1.2. Additional Purchases.

         1.2.1.     At a closing (each, an "Additional Closing," with any of the
               "Base Closing" or Additional Closing being referred to herein
               as a "Closing") to occur at the offices of AMBI concurrently
               with the execution of each of the first three licenses for
               any one or more Option Products or Additional Products, as
               provided in Section 12.2 of the Product Agreement, AHP shall
               purchase from AMBI, and AMBI shall issue to AHP, a number of
               additional shares of common stock equal to $(***) divided by
               (***)% of the average of the closing prices of a share of
               common stock on NASDAQ on each of the 10 trading days up to
               and including the date which is 5 trading days immediately
               preceding such Additional Closing. In addition, as provided
               in Section 7.2 of the Product Agreement, AHP may make certain
               purchases of additional shares of AMBI common stock, the
               number of additional shares of common stock of each purchase
               being equal to $(***) divided by (***)% of the average of the
               closing prices of a share of common stock on NASDAQ during
               the 10 trading days up to and including the date which is 5
               trading days immediately preceding such Additional Closing.
               The shares of common stock to be purchased by AHP at each
               Additional Closing are referred to herein as the "License
               Shares."

         1.2.2.     The purchase price for the License Shares purchased at each
               Additional Closing shall be $(***), and shall be paid by AHP
               at such Additional Closing by wire transfer against the
               delivery by AMBI to AHP of the certificates which represent
               the License Shares purchased at such Additional Closing and
               the opinion of AMBI's counsel to the effect that the License
               Shares are duly authorized, validly issued, fully paid and
               nonassessable, and free and clear from any liens or
               encumbrances of any kind (except restrictions from transfer
               as set forth in applicable securities laws). At such Closing,
               each of AMBI and AHP shall deliver to the other party, a
               certificate by an officer of each company (whose incumbency
               is verified by the Corporate Secretary or an Assistant
               Secretary) certifying that each of the representations and
               warranties (other than with respect to the number of shares
               issued and outstanding in the capitalization) are true and
               correct as of the date of such Closing and that all covenants
               required to be 


<PAGE>

               performed in this Agreement have been performed in all material 
               respects by each such party.

         1.2.3.     By way of example, if on any day AHP executes two licenses
               for Option Products, AHP shall in connection therewith
               purchase common stock for an aggregate purchase price of
               $(***).

         1.2.4.     In the event that the common stock of AMBI is not traded on
               NASDAQ during the period or periods set forth in this Article
               1, the fair market price on each such day shall be determined
               to be the average bid and asked price on each such day that
               the common stock is traded on the over-the-counter bulletin
               board, or if not so traded, as determined in good faith by
               the Board of Directors of AMBI.

     1.3. Hart-Scott-Rodino

         1.3.1.     Prior to the effectuation and as a condition to any Closing
               under this Agreement, AHP shall have: (i) valued its holdings
               of AMBI stock and assets and any stock to be acquired at less
               than $15 million in accordance with Title II of the U.S.
               Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
               amended and the rules promulgated thereunder (16 C.F.R.
               ss.ss.801.1 et seq.); or (ii) determined that no such filing
               is required to be made under the HSR Act or rules; provided,
               however, that in the event that AHP has determined that a
               filing under the HSR Act and rules is required, AMBI and AHP
               shall promptly make all required filings under the HSR Act
               and rules, and shall not effect any Closing hereunder until
               any applicable waiting periods under the HSR Act or rules
               shall have terminated or expired.

2.   Representations And Warranties of AMBI. AMBI represents and warrants to
     AHP that the following statements are true and correct:

     2.1. Organization and Qualification. AMBI is a corporation duly
          organized, validly existing and in good standing under the laws of
          the State of New York and has corporate power to carry on its
          business as it is now being conducted. The character of AMBI's
          properties owned or held under lease and the nature of its
          activities does not make it necessary that AMBI qualify to do
          business in any foreign jurisdiction.

     2.2. Capitalization. The authorized capital stock of AMBI consists of
          65,000,000 shares of Common Stock, par value $.005 per share, and
          5,000,000 shares of Preferred Stock $.01 par value per share. AMBI
          does not have any outstanding securities convertible into or
          exchangeable or exercisable for any shares of the capital stock of
          AMBI, nor are there outstanding any rights to subscribe for or to
          purchase, or any agreements providing for the issuance (contingent
          or otherwise) of, or any options, warrants, calls, commitments,
          understandings, arrangements or claims of any character relating
          to, the capital stock of AMBI or any securities 


<PAGE>

          encumbrances of any kind (except restrictions from transfer as set

     2.3. Authority Relative to This Agreement.

         2.3.1.     AMBI has the corporate power to enter into this Agreement 
               and to carry out its obligations hereunder. The execution and
               delivery of this Agreement, the performance by AMBI of its
               obligations hereunder and the consummation of the
               transactions contemplated hereby have been duly authorized by
               AMBI's Board of Directors in all material respects; the
               issuance of the shares of AMBI Stock pursuant to this
               Agreement have been duly authorized by AMBI's Board of
               Directors; and no other corporate proceedings on the part of
               AMBI are necessary to authorize this Agreement and the
               transactions contemplated hereby.

         2.3.2.     This Agreement has been executed and delivered by AMBI and
               (assuming the valid authorization, execution and delivery of
               this Agreement by AHP) is a valid and binding obligation of
               AMBI enforceable against AMBI in accordance with its terms,
               except as may be limited by or subject to any bankruptcy,
               insolvency, reorganization, moratorium or other similar laws
               affecting the enforcement of creditors' rights generally, and
               subject to general principles of equity. No filing or
               registration with, or authorization, consent or approval of,
               any public body or authority is necessary for the
               consummation by AMBI and its subsidiaries of the transactions
               contemplated by this Agreement.

         2.3.3.     No notice to or filing with, and no authorization, consent 
               or approval of, any domestic or foreign court or any public or
               governmental body or authority is necessary for the
               consummation by AMBI of the transactions contemplated by this
               Agreement (except as may be required by the HSR Act), except
               for notices or filings the failure to give or make, and
               authorizations, consents and approvals the failure to obtain,
               would not materially and adversely affect the ability of AMBI
               to consummate the transactions contemplated hereby, or the
               future conduct of the AMBI's business.

         2.3.4.     Neither the execution and delivery of, nor the consummation
               of the transactions contemplated by, this Agreement will
               result in any of the following:

                      instruments of AMBI, or any material contract,

                      party or by which AMBI or its property is bound;

              2.3.4.2.     an event that would permit any Person to terminate
                      any material contract, agreement, license or
                      instrument to which AMBI is a party or by which AMBI
                      or its property is bound, or to accelerate the
                      maturity of any indebtedness or other material
                      obligation of AMBI;

              2.3.4.3.     the creation or imposition of any lien, mortgage,

                      material asset of AMBI;

              2.3.4.4.     a violation or breach of any statute, ordinance, rule

                      or governmental instrumentality to which AMBI is a
                      party or by which it or any of its properties are
                      bound; or

              2.3.4.5.     a loss or adverse modification under the terms
                      thereof, of any material license, franchise or other
                      authorization granted to or otherwise held by AMBI.

     2.4. Reports and Financial Statements. AMBI has filed all required
          reports and other filings with the Securities and Exchange
          Commission (the "Commission") and all such filings complied in all
          material respects with all applicable requirements of the
          Securities Act of 1933, as amended, and the rules and regulations
          thereunder (the "Securities Act") and/or the Securities Exchange
          Act of 1934, as amended, and the rules and regulations thereunder
          (the "Exchange Act"). As of their respective dates, such reports,
          statements and other written materials did not contain any untrue
          statement of a material fact or omit to state a material fact
          required to be stated therein or necessary to make the statements
          therein, in light of the circumstances under which they were made,
          not misleading. The audited statements and any unaudited interim
          financial statements of AMBI included in such reports have been
          prepared in accordance with generally accepted accounting
          principles applied on a consistent basis and fairly present the
          financial position of AMBI and its subsidiaries as at the dates
          thereof and the results of their operations and changes in
          financial position for the periods then ended, except as indicated
          therein or in the notes thereto.

     2.5. No Material Adverse Change. Since March 31, 1998, as of which date
          the AMBI filed its most recent report on Form 10-Q, there has not
          been any material adverse change in the financial condition,
          results of operations, businesses, properties, assets or
          liabilities of AMBI taken as a whole.


<PAGE>

     2.6. Fees, Commissions and Expenses. AMBI has not paid or agreed to
          pay, nor has it received any claims with respect to, any brokerage
          commissions, finders' fees or similar compensation in connection
          with the transactions contemplated by this Agreement.

     2.7. Investment Company Act. AMBI is not, and after giving effect to
          the transactions described herein will not be, an "investment
          company" as such term is defined in the Investment Company Act of
          1940, as amended.

3.   Representations And Warranties Of AHP. AHP represents and warrants to
     AMBI that the following statements are true and correct in all material

     3.2. Authority Relative to this Agreement.

         3.2.1.     AHP has the corporate power to enter into this Agreement and
               to carry out its obligations hereunder. The execution and
               delivery of this Agreement, the performance by AHP of its
               obligations hereunder and the consummation of the

               and no other corporate proceedings on the part of AHP are
               necessary to authorize this Agreement and the transactions
               contemplated hereby. This Agreement has been executed and
               delivered by the AHP and (assuming the valid authorization,
               execution and delivery of this Agreement by AMBI) is a valid
               and binding obligation of AHP enforceable against AHP in
               accordance with its terms, except as may be limited by or
               subject to any bankruptcy, insolvency, reorganization,
               moratorium or other similar laws affecting the enforcement of
               creditors' rights generally, and subject to general
               principles of equity. Except as referred to herein, no filing
               or registration with, or authorization, consent or approval
               of, any public body or authority is necessary for the

              3.2.2.1.     a default or an event that, with notice or lapse of

                      instruments of AHP, or any material contract,
                      agreement, license or instrument to which AHP is a
                      party or by which AHP, or the property of AHP is
                      bound;

              3.2.2.2.     an event that would permit any Person to terminate
                      any material contract, agreement, license or

                      material asset of AHP;

              3.2.2.4.     a violation or breach of any statute, ordinance, rule
                      or regulation in any material respect applicable to
                      AHP , or any writ, injunction or decree of any court
                      or governmental instrumentality to which AHP is a
                      party or by which AHP, or the property of AHP is
                      bound; or

              3.2.2.5.     a loss or adverse modification under the terms
                      thereof, of any material license, franchise or other

          or similar compensation in connection with the transactions
          contemplated by this Agreement.

     3.4. Investment Representations.

         3.4.1.     The AMBI Stock may be sold or otherwise transferred only if
               registered under the Securities Act, pursuant to an exemption
               therefrom as indicated in an opinion of counsel supplied by
               AHP reasonably acceptable to AMBI and its counsel, or with
               the favorable opinion of counsel to AMBI to the effect that
               such sale or other transfer may be made in the absence of
               registration under the Securities Act. The certificates
               representing the AMBI Stock will be legended to reflect this
               restriction, and stop transfer instructions will apply.

         3.4.2.     AHP represents and warrants that it is purchasing the common
               stock solely for investment solely for its own account and
               not with a view to or for the resale or distribution thereof
               except as permitted under a Registration Statement or as
               otherwise permitted under the Securities Act.

4.   Rule 144 Current Information. AMBI shall timely file periodic reports
     under the Exchange Act to the end that AMBI shall satisfy the
     requirements of Rule 144 in relation to the availability of current
     public information with respect to AMBI.

5.   Participation Registration Rights.

     5.1. If AMBI shall at any time propose the registration under the
          Securities Act of any shares of common stock, AMBI shall give
          notice as promptly as possible (but no less than 10 days before
          filing a registration statement with respect to such registration)
          of such proposed registration to AHP, and AMBI at its sole expense


<PAGE>

          (except with respect to any underwriting discount) shall use its
          best efforts to cause such number of Common Shares as AHP shall
          request within 10 days after the receipt of such notice to be
          included in any such offering; provided, however, that

         5.1.1.     AMBI shall not be required to give notice or include such
               shares in any such registration which is (A) a registration
               of a stock option or compensation plan or of securities
               issued or issuable pursuant to any such plan, or (B) a
               registration of securities proposed to be issued in exchange
               for securities or assets of, or in connection with a merger
               or consolidation with, another corporation;

         5.1.2.     AMBI shall not be required to include such shares in any 
               such registration if AMBI is advised in writing by its investment
               banking firm that the inclusion of such shares would in its
               opinion have a materially adverse effect on such proposed
               offering of its common stock, provided, however, that such
               exclusion shall be made in proportion to the number of shares
               proposed to be included in such offering other than by AMBI,
               and in no case shall such exclusion be more than 10% of the
               total number of shares proposed to be sold in any such
               offering; and

     5.2. AMBI may, without the consent of AHP, withdraw such registration
          statement and abandon the proposed offering in which AHP had
          requested to participate.

     5.3. AMBI shall supply to AHP a reasonable number of copies of all
          registration materials and prospectuses. AMBI and AHP shall
          execute and deliver to each other indemnity agreements which are
          conventional in registered offerings of this type, indemnifying
          AHP for any and all liabilities relating to any registration
          statement, other than based upon information supplied by AHP
          specifically for use therein, and in no case shall AHP's liability
          exceed the proceeds of the sale to AHP under any such offering or
          registration. AHP shall reasonably cooperate with AMBI in the
          preparation and filing of the Registration Statement and
          appropriate amendments thereto, and shall provide to AMBI such
          information with respect to the AHP as AMBI may reasonably require
          in connection therewith.

     5.4. AHP's rights under this Section 5 shall terminate on the later of
          (i) 5 years from the date of this Agreement, or (ii) after AHP
          owns less than 5% of the outstanding common stock of AMBI and is
          free to sell all shares it owns under Rule 144 (k) of the
          Securities Act or any successor provision thereof.

6.   General Provisions

     6.1. Survival of Representations and Warranties. All representations
          and warranties made hereunder shall survive the Closing until
          September 30, 1999, or 12 months from the last Closing in which a

Trademark so that it appears as follows: CARDIA(R). Such notice, where

promotional materials and all other printed and written materials in
connection with the Products manufactured, distributed or sold by W-R under
the CARDIA Trademark.

         5.4   Cooperation and Protection. W-R agrees to reasonably cooperate
with and assist AMBI (at AMBI's sole expense and for AMBI's sole benefit) in

in writing of any infringements, claims or actions by others (which come to
the attention of W-R) in derogation of the CARDIA Trademark.

         5.5   AMBI shall diligently act to terminate any infringement of the
CARDIA Trademark within the Territory, including without limitation
prosecuting a lawsuit or other legal proceeding, at AMBI's sole expense, and

action AMBI takes to terminate infringement and shall be reimbursed by AMBI
for all reasonable out of pocket expenses incurred in connection therewith.

infringement, including without limitation prosecuting a lawsuit or other
legal proceeding, at W-R's own expense; and W-R may retain any recovery it
may receive as a result of its actions to terminate such infringement. AMBI
shall fully cooperate with W-R in any such action taken by W-R, including
without limitation agreeing to be joined as party plaintiff and approving
any reasonable settlement agreement achieved by W-R, and shall be reimbursed
by W-R for all reasonable out of pocket expenses incurred in connection
therewith.

faith by the parties hereto.

         6.2   Second Option. In the event that W-R is licensed by AMBI for a

for the third Option Product, which shall provide for a right for W-R to

         6.3   Extended Option Period. The Option Period defined under Section

month period in which such sales were attained and shall be known as the
"Extended Option Period."

         6.4   Option Exercise.

               6.4.1  On a quarterly basis, AMBI shall provide to W-R
through the Committee, summary information describing any new Option Product
available for license by W-R (the "Disclosure").

               6.4.2  From the date of receiving the Disclosure provided
to W-R pursuant to Section 6.4.1 hereof, W-R shall have the right at any
time prior to (i) the longer of sixty (60) days following W-R's receipt of

               6.4.3  If W-R provides AMBI with an Exercise Notice during

terms of a definitive license agreement relating to the Option Product.
However if the parties are unable within sixty (60) days from the date of

relating to the subject of the Exercise Notice, then AMBI shall have no
further obligation to W-R with respect to such Option Product, and shall be
free to grant licenses to such Option Product to third parties; provided,
however, that such licenses are granted on terms no more favorable to the
third party than those last offered to W-R.

AMBI requests W-R to enter into negotiations for licensing an Option

desires to enter into such negotiations. In the event that W-R does not
desire to enter into negotiations for licensing the Option Product or does
not respond to AMBI within 30 days, then AMBI shall have no further
obligation to W-R with respect to such Option Product, and shall be free to
grant licenses to such Option Product to third parties. In the event that
W-R desires to enter into such negotiations, the parties shall negotiate in
good faith for the licensing of the Option Product. However if the parties
are unable within sixty (60) days from the date that W-R advises AMBI that
it desires to negotiate a license, to negotiate and execute a definitive
license agreement relating to the Option Product, then AMBI shall have no
further obligation to W-R with respect to such Option Product, and shall be

however, that such licenses are granted on terms no more favorable to the
third party than those last offered to W-R. In the event that AMBI elects to
license the subject of the Option Notice to a third party, it shall, if
requested by W-R, provide W-R with a summary of the terms of the proposed
third party license.

               6.4.6  If AMBI requests W-R to enter into negotiations for

results from a clinical trial of the Option Product in humans demonstrating
safety and a reasonable indication of efficacy as measured by an end-point

negotiations for licensing such Option Product. The parties shall negotiate
in good faith the terms of a definitive license agreement relating to the
Option Product. However if the parties are unable within sixty (60) days
from the date of the Exercise Notice, to negotiate and execute a definitive
license agreement relating to the subject of the Exercise Notice, then AMBI
shall have no further obligation to W-R with respect to such Option Product,
and shall be free to grant licenses to such Option Product to third parties;
provided, however, that such licenses are granted on terms no more favorable
to the third party than those last offered to W-R. Such Option Product may
or may not be one that was the subject of an earlier request for W-R to
enter into negotiation for a license, prior to the conditions set forth in
the preceding sentence being in effect.

made in accordance with the terms and conditions of the Stock Purchase
Agreement set forth in Exhibit A.

percentage sharing of expenses will relate to the estimated market size and
the estimated profitability by distribution channel and will be determined
by the Committee.

         9.2   W-R will seek AMBI's counsel and will coordinate all regulatory
submissions which relate to the Product or Other Licensed Products with
AMBI. W-R shall grant AMBI an exclusive license (except for W-R's retained

10       Product Manufacturing and Supply

         10.1  During the term of each license hereunder, each party shall
have the right to manufacture or have manufactured the Product, and shall
offer the other party the right to purchase the fully manufactured Product
at a price which reflects only the direct manufacturing costs, excluding

by a subcontractor to manufacture the product, or (ii) if produced by W-R or
AMBI, the direct costs consisting of labor, material, and facilities for the
actual facilities used for manufacture (i.e. plant and equipment). For the
avoidance of any doubt, direct cost shall also include any incremental cost
increases or decreases attributable to increased capacity utilization
resulting from incremental volume or a rush order by the party placing such
order.  Unallowable overheads shall mean allocations of general and
administrative expenses.

         10.2  All Product shall be delivered F.O.B. the manufacturer's plant
or other place of shipment. The party manufacturing the Products or having
the Product manufactured for it (the "Manufacturing Party") shall deliver
the Product by the applicable order date to the carrier of the Ordering
Party (hereinafter defined) , unless otherwise specified in writing and
agreed to by the parties, to any destinations specified in writing from time
to time by the ordering party. All customs, duties, costs, taxes, insurance
premiums, and other expenses relating to such delivery, shall be at the
expense of the party that placed the order with the Manufacturing Party (the
"Ordering Party").

<PAGE>

         10.3  The Manufacturing Party will package the Products in
accordance with the specifications provided by the Ordering Party, and will
include with each shipment copies of all applicable quality and testing
records, which shall be in a form acceptable for FDA submission (if
applicable).

         10.4  The Ordering Party may reject any portion of any shipment of
Product which (i) does not conform with any applicable specifications
provided to the Manufacturing Party, or (ii) is adulterated or misbranded
within the meaning of the Federal Food, Drug and Cosmetic Act (the "Act"),
or (iii) does not contain quality and testing records in accordance with
Section 10.3 above, or (iv) is not produced in conformance with cGMP for
food, to the extent applicable.

         10.5  In order to reject a shipment, the Ordering Party must (i)
give notice to the Manufacturing Party of the Ordering Party's intent to
reject the shipment within ninety (90) days of receipt together with a
written indication of the reasons for such possible rejection, and (ii) as
promptly as reasonably possible thereafter but in any event within an
additional 30 days, provide the Manufacturing Party with notice of final
rejection and the full basis therefor. After notice of intention to reject
is given, the Ordering Party shall cooperate with the Manufacturing Party in
determining whether rejection is necessary or justified. If no such notice
of intent to reject is timely received, the Ordering Party shall be deemed
to have accepted such delivery of Product. The Manufacturing Party will have
the opportunity to test any rejected Product. The Manufacturing Party, at
its sole discretion, will rework or replace Product, or refund purchase
price. If the parties cannot agree on whether rejection is appropriate,
Product will be tested by an independent third party, and the party deemed
to be incorrect in its evaluation of the rejection will pay the cost of the
independent party's fees.

         10.6  The Manufacturing Party shall pay the return transportation
and delivery costs in addition to any refund of the purchase price of
properly rejected Product.

         10.7  Unless the Manufacturing Party requests the return to it of a
rejected batch of Product within sixty (60) days of receipt of the Ordering
Party's final notice of rejection, the Ordering Party shall destroy such
batch promptly in an environmentally acceptable manner and provide the
Manufacturing Party with certification of such destruction. The Ordering
Party shall, upon receipt of the Manufacturing Party's request for return,
promptly dispatch said batch to the Manufacturing Party, at Manufacturing
Party's cost.

         10.8  Each party hereby agrees to ascertain and comply with all
applicable laws and regulations and standards of industry or professional
conduct in connection with the use, distribution or promotion of Product,
including without limitation, those applicable to product claims, labeling,
approvals, registrations and notifications.

         10.9  Each party further agrees to keep for three years after
termination of this Agreement records of all Product sales and customers
sufficient to adequately administer a recall of any Product and to
reasonably cooperate in any decision by the other party to recall, retrieve
and/or replace any Product.

<PAGE>

         10.10 In the event of a recall of any of the Product required by a
governmental agency or authority of competent jurisdiction or if recall of
any of the Product is deemed advisable by the parties, such recall shall be
promptly implemented and administered by the parties in a manner which is
appropriate. The costs of any such recall shall be borne by the party or
parties whose actions caused the recall to be necessary. The provisions and
obligations of this Sections shall survive any termination of this
Agreement.

reported by NASDAQ for the ten (10) trading days immediately preceding the
date of purchase. All equity purchases shall be made in accordance with the
terms and conditions of the Stock Purchase Agreement set forth in Exhibit A.

         11.2  W-R shall further purchase an additional (***) worth of
newly-issued AMBI Common stock from AMBI upon execution of each license for
an Option Product or an Additional Product, up to a maximum of three (3)
such Option Products and Additional Products. The price for such Common
Stock shall be equal to (***)% of the average closing prices of AMBI Common
Stock as reported by NASDAQ for the ten (10) trading days immediately
preceding the date of purchase. All equity purchases shall be made in
accordance with the terms and conditions of the Stock Purchase Agreement set
forth in Exhibit A.

         11.3  Royalty on Products.

               11.3.1  Because the parties agree that the Cardia Patent
Rights, the CARDIA Trademark, and the Know-How relating to the Product each
deserve royalty payments of differing amounts, and each would last for a
different term, and because the parties have determined, solely for reasons
of convenience, that a blended royalty rate for the Cardia Patent Rights,
the CARDIA Trademark, and the Know-How relating to the Product will be
advantageous for both AMBI and W-R, the parties hereby agree that W-R shall
pay to AMBI in respect of Net Sales of Product made by W-R and its
Affiliates running royalties of (***)% for so long as W-R shall sell the
Product. However, if the 

<PAGE>

total amount of royalties paid by W-R to AMBI in any year from the Effective
Date of this Agreement for the Product is less than (***), then within thirty
(30) days of the end of such year, W-R shall pay to AMBI the difference between
(***) and the total amount of royalties paid in such year for the Product.

         11.4  AMBI shall have the right and option to assign its right to
receive any or all payments under this Agreement to one or more of its
Affiliates. AMBI shall notify W-R in writing if it exercises such option,
and W-R shall provide reasonable cooperation in connection with such revised
payment arrangements.

         11.5  Royalties shall be paid within forty-five (45) days of the end
of each calendar quarter with respect to royalty-bearing sales and use
occurring in that quarter. Late payments will bear interest at the Prime
interest rate as reported by the Wall Street Journal on the date immediately
preceding the date on which such payment is made.

         11.6  W-R and its Affiliates shall keep and maintain detailed and
accurate books and records with regard to Net Sales, royalties and the
calculation thereof. A Certified Public Accountant selected by AMBI
(reasonably acceptable to W-R) shall be entitled to review and audit such
books and records related to the payment of royalties hereunder from time to
time during normal business hours upon reasonable notice to W-R and at
AMBI's expense; provided that W-R will bear any such expense if the review
or audit shows an underpayment of more than 5% for the applicable period and
furthermore W-R shall remit promptly to AMBI the amount of any underpayment
and interest thereon. Such Certified Public Accountant's report to AMBI
shall be limited to the accuracy of W-R's royalty report(s) and payments and
shall contain no other information relating to the sales of the Products.

12       Committee.

         12.1  The parties shall create and structure a committee
(hereinafter referred to as the "Committee") which will have equal
membership of up to three (3) members from each party, and that will have
the responsibility to coordinate activities between AMBI and W-R. The
Committee shall be responsible for, without limitation, sharing relevant
information on the Product, Other Licensed Products, Option Products and
Additional Products between the parties. Such information shall include
information relevant to marketing and other promotion and sales activities,
manufacturing and quality control, clinical and pre-clinical trial design,
implementation, publications, regulatory and other governmental issues. The
Committee will prepare and approve a plan (hereinafter referred to as a
"Plan") for the Product and for each of the Other Licensed Products, which
shall include, without limitation, development and commercialization
budgets, and development and commercialization responsibilities for the
Retail Channels in the Territory, and Canada where appropriate.

         12.2  All decisions of the Committee must receive the consent of (i)
a majority of Committee members present in person or by telecommunications,
and (ii) such majority must include representatives of both parties.

<PAGE>

         12.3  W-R shall keep the Committee informed on a timely basis as to
developments within W-R which could reasonably have a material impact on the
Product and Other Licensed Products. All information provided to AMBI
pursuant to the operation of this provision shall be Proprietary Information
and treated pursuant to the terms of confidentiality recited in the
Agreement. AMBI shall keep the Committee informed on a timely basis as to
developments within AMBI that could reasonably have a material impact on the
Product and Other Licensed Products. All information provided to W-R
pursuant to the operation of this provision shall be deemed Proprietary
Information and treated pursuant to the terms of confidentiality recited in
the Agreement.

         12.4  The Committee shall decide how best to distribute Product and
Other Licensed Products in those areas in which neither party has expertise.

         12.5  In the event that one party does not wish to proceed to
develop a Plan for an Other Licensed Product, the other party shall have the
right to develop and/or commercialize that product on its own, at its own
expense with no obligation to share its plan with the other party.

13       Clinical Studies

         13.1  AMBI shall grant W-R access to clinical studies of the Product
relating to efficacy and safety conducted prior to the Effective Date of the
Agreement.

         13.2  Expenses related to future clinical studies needed to
demonstrate efficacy and/or safety of the Product and Other Licensed
Products shall be shared by AMBI and W-R.

         13.3  The sharing of clinical trial expenses pursuant to Section
13.2 will be determined by the Committee based upon the applicable Plan and
will be set forth in the agreement. In general, the percentage sharing of
expenses will relate to the estimated market size and the estimated
profitability by distribution channel.

14       Representations, Warranties and Indemnities.

         14.1 (a) AMBI represents and warrants to W-R that AMBI has full
power and authority to enter into this Agreement and to grant the licenses

              (b) AMBI agrees to hold W-R and its Affiliates harmless

granted to W-R.

              (c) AMBI represents and warrants that the use of the

<PAGE>

              (d) AMBI represents and warrants that it has not granted any
license, right, or interest in or to the Products or any method of their
manufacture or use to any third party, which are inconsistent with the licenses,
rights and interests granted to W-R, e.g., AMBI has granted the right to Wixon
to manufacture CARDIA Salt Alternative for sales to AMBI.

              (e) Promptly following the Effective Date, AMBI shall initiate,
with W-R's assistance, discussions with Oriola oy of Finland ("Oriola"), the
registered owner of the Cardia Trademark towards negotiating a royalty for the

represents and warrants that it will negotiate the royalty with Oriola for use
of the Cardia Trademark after termination of the Cardia Patent Rights, and will
pay the agreed-upon royalty to Oriola.

         14.2  W-R represents and warrants to AMBI that W-R has full power
and authority to enter into this Agreement and will carry on its
development, marketing and sales and other obligations hereunder promptly,
in good faith and with commercially reasonable efforts.

         14.3  AMBI shall indemnify, defend and hold harmless W-R, its
Affiliates and their respective officers, directors, agents and employees
(the "W-R Indemnitees"), against any liability, damage, loss or expense
(including but not limited to fees and disbursements of counsel incurred by
the W-R Indemnitee in any action or proceeding between AMBI and the W-R
Indemnitee or between the W-R Indemnitee and any third party or otherwise)
resulting from a breach of its warranties, from infringement by the Product
of any patent within the Territory, or defective Product manufactured by
AMBI or its Affiliates (or their designees) .

         14.4  W-R shall indemnify, defend and hold harmless AMBI, its
Affiliates and their respective officers, directors, agents and employees
(the "AMBI Indemnitees"), against any liability, damage, loss or expense
(including but not limited to fees and disbursements of counsel incurred by
the AMBI Indemnitees in any action or proceeding between the W-R and the
AMBI Indemnitee or between the AMBI Indemnitee and any third party or
otherwise) arising from any product liability or other lawsuit, claim,
demand or other action brought with respect to (i) development work and
clinical trials conducted by W-R or its Affiliates in relation to the
Product, (ii) Product manufactured by W-R or its Affiliates, or (iii)
Product imported, distributed or sold by W-R or its Affiliates, except in
this case of (iii) defective Product manufactured by AMBI or its Affiliates
(or their designees).

         14.5  The party claiming indemnification (the "Indemnified Party")
from the other (the "Indemnifying Party") shall promptly notify the
Indemnifying Party in writing of any lawsuit, claim, demand or other action
or threat thereof in respect of which indemnification may be sought under
this Section 14, shall give the Indemnifying Party complete control of the
defense and/or settlement of the suit and to the extent allowed by law, the
Indemnified Party shall cooperate with the Indemnifying Party in defending
or settling any such lawsuit, claim, demand or other action. No settlement
of any claim, suit 

<PAGE>

or threat thereof for which indemnification is sought, shall be made without the
prior written approval of the Indemnifying Party.

15       Confidentiality.

         15.1  Each party recognizes the importance to the other of the other's
Proprietary Information. In particular W-R recognizes that AMBI's Proprietary
Information (and the confidential nature thereof) are critical to the business
of AMBI and that AMBI would not enter into this Agreement without assurance that
such Proprietary Information and the value thereof will be protected as provided
in this Section 15 and elsewhere in this Agreement. Accordingly, each party
agrees as follows:

         15.2  The Receiving Party agrees (i) to hold the Disclosing Party's
Proprietary Information in confidence as a fiduciary and to take all
reasonable precautions to protect such Proprietary Information (including,
without limitation, all precautions the Receiving Party employs with respect
to its own confidential materials), (ii) not to divulge any such Proprietary
Information or any information derived therefrom to any third person, and
(iii) not to make any use whatsoever at any time of such Proprietary
Information except as expressly authorized in this Agreement. Any employee
given access to any such Proprietary Information must have a legitimate
"need to know" and shall be similarly bound in writing. Without granting any
right or license, the Disclosing Party agrees that the foregoing clauses
(i), (ii) and (iii) shall not apply with respect to information the
Receiving Party can document (w) is in or (through no improper action or
inaction by the Receiving Party or any Affiliate, agent or employee) enters
the public domain or (x) was rightfully in its possession or known by it
prior to receipt from the Disclosing Party, or (y) was rightfully disclosed
to it by another person without restriction, or (z) was independently
developed by it by persons without access to such information and without
use of any Proprietary Information of the Disclosing Party. The Receiving
Party must promptly notify the Disclosing Party of any information it
believes comes within any circumstance listed in the immediately preceding
sentence and will bear the burden of proving the existence of any such
circumstance by clear and convincing evidence. Each party's obligations
under this Section 16 shall terminate 5 years after the termination of this
Agreement.

         15.3  Except as provided herein, immediately upon termination of
this Agreement, the Receiving Party will turn over to the Disclosing Party
or destroy all Proprietary Information of the Disclosing Party and all
documents or media containing any such Proprietary Information and any and
all copies or extracts thereof. Each party may retain in its legal
department one (1) copy of the Proprietary Information of the other party as
evidence of its obligations hereunder.

         15.4  The Receiving Party acknowledges and agrees that due to the
unique nature of the Disclosing Party's Proprietary Information, there can
be no adequate remedy at law for any breach of its obligations hereunder,
that any such breach may allow the Receiving Party or third parties to
unfairly compete with the Disclosing Party resulting in 

<PAGE>

irreparable harm to the Disclosing Party, and therefore, that upon any such
breach or any threat thereof, the Disclosing Party shall be entitled to seek
appropriate equitable relief in addition to whatever remedies it might have at
law and to be indemnified by the Receiving Party from any loss or harm,
including, without limitation, lost profits and attorney's fees, in connection
with any breach or enforcement of the Receiving Party's obligations hereunder or
the unauthorized use or release of any such Proprietary Information. The
Receiving Party will notify the Disclosing Party in writing immediately upon the
occurrence of any such unauthorized release or other breach. Any breach of this
Section 15 will constitute a material breach of this Agreement.

16       Ownership and Patent Matters.

         16.1  Except as explicitly set forth elsewhere in this Agreement, as
between the parties, AMBI is the sole owner of all right, title and interest to
the Product, Other Licensed Products, Option Products, Additional Products,
Know-How, and other Proprietary Rights in relation thereto.

         16.2  AMBI shall file and prosecute patent applications and maintain
patents relating to the Product, Other Licensed Products, Option Products,
and Additional Products, .

         16.3  If W-R becomes aware of any product or activity of any third
party that involves infringement or violation of any of AMBI's Cardia Patent
Rights, Patent Rights or other Proprietary Rights, then W-R shall promptly
notify AMBI in writing of such infringement or violation. AMBI may in its
discretion take or not take whatever action it believes is appropriate; if AMBI
elects to take action, W-R will fully cooperate therewith at AMBI's expense. If
AMBI does not, within ninety (90) days after receipt of such a notice of a
patent infringement within the scope of a W-R's license hereunder, commence
action directed towards restraining or enjoining such patent infringement, W-R,
so long as it is an exclusive licensee hereunder, may take such legally
permissible action as it deems necessary or appropriate to enforce AMBI's Cardia
Patent Rights, Patent Rights and restrain such infringement. AMBI agrees to
cooperate reasonably in any such action initiated by W-R including supplying
essential documentary evidence and making essential witnesses then in AMBI's
employment available. As part of such cooperation, W-R may join AMBI as a party,
if the need arises, although such joinder shall be entirely at W-R's expense.
W-R will indemnify AMBI for any damages, expenses, costs and fees in connection
with W-R's actions under this Section 16.3. Nothing in this Section 17.3 allows
W-R or requires AMBI to disclose Proprietary Information of AMBI. If AMBI
initiates and prosecutes any such an action under this Section 16.3, all legal
expense (including court costs and attorneys' fees) shall be for AMBI's account
and it shall be entitled to all amounts awarded by way of judgment, settlement
or compromise. Similarly, if W-R initiates and prosecutes such an action, all
legal expenses (including court costs and attorneys' fees) shall be for W-R's
account and it shall be entitled to all amounts awarded by way of judgment,
settlement, or compromise.

<PAGE>

         16.4  AMBI and W-R agree to work cooperatively regarding issues
concerning patents and Proprietary Rights and similar matters and to exercise
reasonable business judgment in carrying out the objects of this Agreement to
avoid exposing either party to liability under patent laws of the United States
and Canada, if applicable. Each party represents and warrants that it is not
aware of infringement or potential infringement issues relating to the Product
that have not been communicated to the other in writing before Effective Date.

17       Dispute Resolution.

         17.1  In the event that any dispute arises between the parties in
connection with this Agreement, the representatives of each party responsible
for the subject matter of such dispute shall use good faith efforts to resolve
such dispute promptly. In the event that such dispute cannot be resolved by the
parties' representatives, the matter shall be submitted to the parties'
respective Chief Executive Officers ("CEOs") or their designees who have full
decision making authority for resolution.

         17.2  In the event that the CEOs or their designees who have full
decision making authority cannot reach resolution of the issue, each party shall
be free to pursue other remedies.

18       Term and Termination.

         18.1  Unless this Agreement is terminated earlier pursuant to this
Section 18, this Agreement will remain in effect in perpetuity (the "Term").

         18.2  If a party breaches a material provision of this Agreement
(e.g. failure to make payments when due), the other party may terminate this
Agreement upon sixty (60) days prior written notice, unless the breach is
cured within such sixty (60) day period (the "Cure Period"). In the event of
a material breach by W-R under this Agreement which is not cured within the
Cure Period, AMBI shall, in its sole discretion, have the option of
terminating the exclusivity of W-R's license hereunder in respect of the
Product and Other Licensed Products, or in respect of the Product or a
particular Other Licensed Products, instead of terminating this Agreement.
If AMBI wishes to exercise the foregoing option, it shall so notify W-R in
writing prior to the expiration of the Cure Period.

         18.3  In the event of any termination of this Agreement, any accrued
rights to payment, and causes of action or remedies for breach, shall
survive such termination. In the year of termination of this Agreement, the
minimum $(***) royalty for Product set forth in Section 11.3.1, shall be
prorated to the date of termination. In addition, Sections 15, 21, 24, and
other provisions which by their nature should survive termination of this
Agreement, shall survive termination of this Agreement.

         18.4  W-R may terminate the licenses for Product and the Cardia
Trademark upon one year's prior written notice. During the one year period
between notice and 

<PAGE>

termination, W-R agrees to spend no less for marketing and sales expense for
Product than the average of the total expenditures for marketing and sales for
Product in each of the three years prior to notice.

         18.5  In the event of any termination of this Agreement all of W-R's
rights in relation to the Product, Other Licensed Products, Know-How and all
Proprietary Rights in relation thereto, shall revert to AMBI, and W-R shall
promptly assign to AMBI any and all regulatory filings and approvals held by
W-R in relation to the Product or Other Licensed Products.

         18.6  Neither party shall incur any liability whatsoever for any
damage, loss or expenses of any kind suffered or incurred by the other
arising from or incident to any termination of this Agreement (or any part
thereof) by such party which complies with the terms of the Agreement
whether or not such party is aware of any such damage, loss or expenses.

         18.7  Termination is not the sole remedy under this Agreement and,
whether or not termination is effected, all other remedies will remain
available.

<PAGE>

Agreement may not be assigned or transferred except (i) rights to payment of

all the assets, business or stock of a party to which this Agreement relates.

with draft press releases for review and comment. Each party agrees to review
and comment promptly on draft press releases received from the other party.

23       Competition

         Nothing in this Agreement will be deemed to preclude W-R from
developing, selling, promoting or otherwise marketing at any time compound(s) or
composition(s) which compete, directly or indirectly, against the Product,
Option Products, Other Licensed Products or Additional Products. Nothing in this
Letter or in the Agreement will be deemed to preclude AMBI from developing,
selling, promoting or otherwise marketing at any time compound(s) or
composition(s) which compete, directly or indirectly, against products sold by
W-R or its Affiliates.

24       Subrogation

<PAGE>

         The Cardia Patent Rights and the Cardia Trademark are exclusively
licensed, with the right to sublicense, by Oriola to AMBI. AMBI will notify

permit W-R to make such payments on behalf of AMBI directly to Oriola. Any
payment made by W-R hereunder shall be creditable against other sums due
AMBI.

         25.1  Prior to the closing of the announced merger between AHP and
Monsanto Chemical Company, W-R may enter into discussions with the
appropriate personnel at Monsanto to ascertain Monsanto's interest in
providing assistance to W-R as it relates to W-R's obligations under this
Agreement. W-R will notify AMBI prior to such proposed discussions and will
keep AMBI informed as to the nature of such discussions. Should W-R propose
to enter into an agreement with Monsanto relating to this Agreement or any
license granted by AMBI prior to the closing of the AHP/Monsanto merger, W-R
must secure AMBI's written consent.

         25.2  If the Committee believes that it is in W-R's best interest to
offer samples of Product to physicians, dietitians, nutritionists,
pharmacist, etc. that W-R details or otherwise communicates with, then AMBI
will provide samples of Product to W-R for such distribution at AMBI's
actual cost of manufacturing (without overheads) for so long as AMBI
manufactures Product. No royalty under Section 11.3.1 shall be due AMBI on
such Products.

         25.3  W-R shall have the right to offer certain of its products for
AMBI's consideration for distribution by AMBI through the Direct Response
Distribution Channels (such as Heart's Content). If the parties agree to
such distribution, AMBI will purchase such product(s) from W-R under the

requires any changes to the Agreement, the parties will in good faith modify
the Agreement so that it is acceptable to the government.

         25.5  W-R may, at its option, distribute AMBIis Heartis Content
catalog (following W-R medical and legal approval thereof which approval

products in Heartis Content at no charge to W-R.

         25.6  Amendment and Waiver. Except as otherwise expressly provided
herein, any provision of this Agreement may be amended and the observance of
