Item 2.    Acquisition of Assets

         On January 21, 1999, AMBI Inc. (the "Company") acquired substantially
all of the assets and assumed certain of the liabilities of Optimum Lifestyle,
Inc. ("Seller") relating to the business (the "Business") of developing,
producing, and marketing dietary supplements, primarily nutrition bars which are
marketed under the trademark "Lite-Bites" through the QVC Inc. television
network. These products are manufactured to proprietary specifications under
agreements with third party manufacturers. The purchase price paid by the
Company at the closing was $6,000,000 in cash (the "Cash Purchase Price") and
1,304,347 shares of common stock of the Company. Additional contingent payments
will be made to the Seller depending primarily on sales levels of the Business
achieved during the five year period following the closing, payable in preferred
stock of the Company and up to $5,500,000 in cash. A portion 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 (the
"Bank"), which Loan Agreement also amended and restated a prior agreement with
the Bank, and the balance was funded from internal working capital. Loans from
the Bank bear interest at the prime rate plus 1% and are due February 1, 2002.

Exhibit 2.1


                    AGREEMENT OF PURCHASE AND SALE OF ASSETS


AGREEMENT OF PURCHASE AND SALE OF ASSETS ("Agreement") is made January 19, 1999
by and among DEAN RADETSKY and CHERYL RADETSKY (each, a "Shareholder" and
collectively the "Shareholders"), OPTIMUM LIFESTYLE, INC., a California
corporation (the "Seller"), and AMBI INC., a New York corporation ("Purchaser").
Shareholders own all of the outstanding shares of capital stock of Seller.


                              W I T N E S S E T H:


IN CONSIDERATION of the mutual covenants and agreements hereinafter set forth,
the parties hereby agree as follows:

1.       Purchase and Sale of Business and Assets.

         (a)      Purchase and Sale.

                  (i) Subject to and upon the terms and conditions set forth in
         this Agreement, Seller will sell, transfer, convey, assign and deliver
         to Purchaser, and Purchaser will purchase, at the closing described in
         Section 6 (the "Closing"), all of the business, assets, properties,
         goodwill and rights of Seller as a going concern, of every nature, kind
         and description, tangible and intangible, wheresoever located and
         whether or not carried or reflected on the books and records of Seller,
         except for the Excluded Assets (as defined in Section 1(d)). Such
         business, assets, properties, goodwill and rights other than the
         Excluded Assets are hereinafter sometimes collectively called "Seller's
         Assets."

                  (ii) The purchase and sale hereunder shall be deemed made as
         of the opening of business on January 1, 1999 (the "Effective Date"),
         so that, once the Closing has occurred, the economic benefits of
         Seller's business from and after the Effective Date shall be deemed to
         have accrued to the benefit of Purchaser, and the economic burdens of
         Seller's business from and after the Effective Date shall be deemed to
         be for the account of Purchaser. The parties will at the Closing make
         such payments among themselves as shall be necessary to put the parties
         in the same economic position they would have occupied had the Closing
         occurred on the Effective Date (the "As-Of Adjustments").

         (b)      Except as set forth in Section 1(d), Seller's Assets include,
                  without limitation:

                  (i) All of Seller's merchandise, inventories, materials and
         supplies used in the business of Seller including items in transit from
         vendors (hereinafter collectively referred to as "Inventory");

                  (ii) All accounts receivable, notes receivable and all accrued
         or unaccrued payments or obligations which have inured or shall inure
         to the benefit of Seller as of the date of Closing (the "Closing
         Date");


                                       1
<PAGE>

                  (iii) All machinery, equipment, office equipment, leasehold
         improvements, fixtures, and supplies of Seller existing as of the

         office equipment and furniture currently located in the personal
         residence of the Shareholders;

                  (iv) All of the right, title and interest of Seller in and to
         all United States and foreign patents, trademarks and copyrights,
         application for any of the foregoing, if any, all inventions and
         technology of Seller, including, but not limited to, manufacturing
         information, know-how and processes, quality control and quality
         assurance information, testing specifications and procedures, product
         formulations, and other trade secrets, and any and all variations or
         derivations thereof, and in and to all logos, insignias and advertising
         materials of Seller bearing the name "LITE BITES" or "HEALTHY BITES"
         and/or relating to the Seller's Assets, and all trade dress, trade
         names, and trademarks and trademark applications of Seller in any way
         related to the business of making, having made, using, selling and
         furnishing dietary supplements and other nutrition food products (the
         "Business");

                  (v) All of the right, title and interest in and to all leases
         of real and personal property to which Seller is a party with respect
         to the Business; Purchaser will succeed to the current month-to-month
         lease and will seek to amend the term thereof to a six-month or other
         term;

                  (vi) All of the right, title and interest of Seller in and to
         all agreements, contracts and orders, license agreements, franchise and
         all other agreements and contracts with respect to the Business,
         including but not limited to those described on the Disclosure Schedule
         (as hereinafter defined) as "Assumed Contracts";

                  (vii) The lists of Seller of suppliers and of clients which
         exist as of the Closing Date;

                  (viii) To the extent dated from and after January 1, 1997 or
         relating to any period from and after January 1, 1997, all of Seller's
         files, records and correspondence, including without limitation,
         employee lists and files, and sales and advertising materials and
         records, sales and purchase correspondence (reference is made to
         Section 7(f) for Purchaser's rights with respect to all files and
         materials prior to January 1, 1997);

                  (ix) All deposits, credits and prepaid items related to or
         arising from the Business;

                  (x) The goodwill of Seller;

                  (xi) The assets referred to in the form of Bill of Sale
         attached hereto as Exhibit A to this Agreement;

                  (xii) The assets (except for Excluded Assets, as defined in
         Section 1(d)) reflected on the December Balance Sheet (as defined in
         Section 10(f)), with only such dispositions of such assets reflected on
         the December Balance Sheet as shall have occurred in the ordinary
         course of Seller's business between the date thereof and the Closing
         and the existence of which shall not constitute a breach of any
         representation or warranty by Seller or either Shareholder hereunder;

                  (xiii) All other assets, properties, rights and businesses of
         every kind and nature owned or held by Seller relating to the Business,
         or in which Seller has an interest, on the


                                       2
<PAGE>

         date hereof, known or unknown, fixed or unfixed, choate or inchoate,
         accrued, absolute, contingent or otherwise, whether or not specifically
         referred to in this Agreement.

         (c)      Seller's Assets shall be conveyed free and clear of all
                  liabilities, obligations, liens and encumbrances excepting
                  only those liabilities and obligations which are expressly to
                  be assumed by Purchaser hereunder and those liens and
                  encumbrances securing the same which are specifically
                  disclosed herein or expressly permitted by the terms hereof.

         (d)      Prior to the Closing, Seller shall distribute to its
                  shareholders an amount of cash and accounts receivable (if
                  necessary) equal to its good faith estimate of undistributed
                  profits (including amounts in its "AAA" account, if any, but
                  excluding any bonus awarded to Marvin Segel in 1998) through
                  the Effective Date, except to the extent that such
                  distributions would reduce estimated working capital as of the
                  Effective Date to less than $50,000. Any such undistributed
                  profit which is not distributed by Seller to its shareholders
                  prior to the Closing is considered an Undistributed Amount.
                  The Undistributed Amount will be verified by Purchaser within
                  thirty days of Closing. Purchaser shall pay the Undistributed
                  Amount, if any, to Seller according to the following schedule:
                  (i) if the Undistributed Amount is less than $100,000,
                  Purchaser shall pay Seller the full amount promptly upon
                  verification of the amount, (ii) if the Undistributed Amount
                  is between $100,000 and $250,000, the Purchaser shall pay
                  Seller half each within 30 and 60 days of Closing, (iii) if
                  the Undistributed Amount is between $250,000 and $400,000,
                  then Purchaser shall pay one-third each within 30, 60 and 90
                  days of Closing, and (iv) if the Undistributed Amount is
                  greater than $400,000, then Purchaser shall pay one-fourth
                  each within 30, 60, 90 and 120 days of Closing. All payments
                  of Undistributed Amounts shall be offset by the Purchaser
                  against the First Contingent Payment (as hereinafter defined)
                  in the manner provided in Section 2(e)(i). Cash or receivables
                  distributed by Seller to its shareholders to satisfy
                  undistributed profit distribution prior to the Closing (the
                  "Pre-Closing Dividend"), the assets reflected on the December
                  Balance Sheet (as hereinafter defined) as "Non-Assumed
                  Accounts Receivables" and the assets designated on Schedule
                  1(d) (collectively the "Excluded Assets") are excluded from
                  Seller's Assets. The term "working capital" means the amount,
                  determined as of the Effective Date by which cash, accounts
                  receivable and inventory exceed trade accounts payable. If,
                  upon verification of the Undistributed Amount it is determined
                  that Seller has distributed assets in excess of actual profits
                  through the Effective Date, then Seller shall repay Purchaser
                  pursuant to the same terms and schedule as stated above.

2.       Purchase Price.

         (a)      In consideration of the sale, transfer, conveyance, assignment
                  and delivery by Seller of the Seller's Assets to Purchaser,
                  and in reliance upon the representations and warranties made
                  herein by Seller and Shareholders, Purchaser will, in full
                  payment thereof, pay to Seller a purchase price (the "Purchase
                  Price") which shall be payable as and to the extent provided
                  in Sections 2(b) through 2(i) and which shall consist of:

                  (i) $6,000,000 (the "Cash Payment"), plus

                  (ii) the Post-Closing Cash Adjustment (as defined in Section
         2(c)), plus

                                       3
<PAGE>

                  (iii) a number of shares of Purchaser's fully paid and
         nonassessable Common Stock (hereinafter "Purchase Price Shares")
         calculated under Section 2(d)), plus

                  (iv) the First Contingent Payments (as defined in Section
         2(e)), plus

                  (v) the Second Contingent Payments (as defined in Section
         2(f)), plus

                  (vi) the Third Contingent Payment (as defined in Section 2(g).

         (b)      Purchaser shall pay the Cash Payment at the Closing by wire
                  transfer to accounts designated by Seller.

         (c)      The Post-Closing Cash Adjustment is as follows:

                  (i) The "Post-Closing Cash Adjustment" shall equal the amount,
         if any, by which net sales of the Business during the period from
         October 1, 1998 through March 31, 1999 shall exceed $3,430,000, but in
         no event shall the Post-Closing Cash Adjustment be greater than
         $1,500,000. By mutual written agreement, in the event of the occurrence
         of material, non-ordinary events, the parties may determine that an
         alternative means of calculating the Post-Closing Cash Adjustment is
         necessary; but in the absence of such agreement, such calculation shall
         be made as provided in the preceding sentence.

                  (ii) The Post-Closing Cash Adjustment shall be determined by
         Purchaser's chief financial officer or other designated officer subject
         to the provisions of Section 3. Within 30 days after such
         determination, Purchaser shall pay the Post-Closing Cash Adjustment by
         wire transfer to accounts designated by Seller.

                  (iii) "Net sales" means sales of Products (as hereinafter
         defined) net of returns, discounts and allowances consistent with past
         practices. "Products" means products currently marketed by Seller under
         the name "Lite Bites" or "Healthy Bites" or the same product or any
         substantially similar product marketed under any name by Purchaser.

         (d)      Purchase Price Shares.

                  (i) The Purchase Price Shares means 1,304,347 shares of common
         stock of Purchaser ("Common Stock").

                  (ii) [omitted]

                  (iii) The Purchase Price Shares shall be issued to Seller
         and/or its designees (the "Designees") at the Closing, provided that
         each stock recipient has made customary investor representations to
         Purchaser.

                  (iv) By mutual written agreement, the parties may agree that,
         in lieu of the Purchase Price Shares or any agreed portion thereof,
         Purchaser will at the Closing pay to Seller cash in an agreed amount.

         (e)      First Contingent Payments.

                  (i) With respect to each of the first three anniversaries of
         the Closing, at the times and as otherwise set forth in Section
         2(e)(iii), Purchaser will be obligated to pay to Seller:

                  (1)      a percentage of $1,000,000 which is equal to the
                           percentage that (x) the number of days in which
                           Purchaser engaged in the Base Business (as
                           hereinafter defined) during the 12-month period prior
                           to such anniversary is of (y) 365; and

                  (2)      if Purchaser on any date (the "termination date")
                           before the third anniversary of the Closing ceases to
                           engage in the Base Business, then on each of such
                           anniversaries which occurs thereafter, Purchaser will
                           be obligated to pay to Seller an amount equal to
                           $1,000,000 times the Base Arms Sales Ratio (as
                           hereinafter defined) for (x) the 12-month period
                           prior to such anniversary or (y), if the termination
                           date occurred during such 12-month period, for the
                           period beginning after the termination date.

                  (ii) In no event shall Purchaser be obligated to pay to Seller
         an aggregate amount in excess of $1,000,000 with respect to any
         anniversary aforesaid.

                  (iii) Payments under this Section 2(e) are referred to herein
         as "First Contingent Payments."

                  (iv) The "Base Business" means the business of selling
         Products through (1) on-air sales over any television shopping network
         which has substantially the market reach of QVC or HSN (a "television
         shopping network"), (2) any non- on-air distribution arms of any
         television shopping network, including, for example, the internet,
         direct mail, telephone sales, reorders, and catalog etc. arms of any
         television shopping network (collectively, "television shopping arms"),
         and (3) infomercials on any television station, provided that:

                  (1)      If Purchaser at its discretion terminates on-air
                           sales over television shopping networks as a channel
                           for the sale of Products, then the Base Business
                           shall also include sales of Products in any business
                           channel; and

                  (2)      If television shopping networks terminate on-air
                           television sales of Products or refuse to engage in
                           the on-air sale of Products on terms substantially
                           similar to those in effect on the date hereof in
                           Seller's sales through QVC, Purchaser shall no longer
                           be deemed to be engaged in the Base Business whether
                           or not it sells Products through television shopping
                           arms, or through infomercials, or through other
                           business channels.

                  (v) The "Base Arms Business" means the business of selling
         Products through television shopping arms, but only so long as such
         sales are at the annual rate of not less than $2,000,000.

                  (vi) The "Base Arms Sales Ratio" for any period means sales of
         the Base Arms Business in such period (net of returns, discounts and
         allowances consistent with past practice), divided by (1) $500,000,
         multiplied by (2) the number of whole calendar months in such period.

                                       5

                  (vii) The First Contingent Payment for each anniversary date
         aforesaid shall be determined within 30 days after such anniversary,
         and shall be paid promptly thereafter by wire transfer to accounts
         designated by Seller. However, by notice given by Seller to Purchaser
         not less than 20 days before a payment is due hereunder, Seller may
         elect to receive all or 50% of such payment in shares of Common Stock
         valued at the average closing price of the Common Stock during the 10
         trading days prior to the anniversary for which such payment is being
         made.

                  (viii) In the event that Purchaser's chief financial officer
         or other designated officer shall determine, subject to the provisions
         of Section 3, that Seller's working capital as of the Effective Date
         (after giving effect to the distributions permitted under Section 1(d))
         is less than $50,000, the amount of such deficiency shall be deducted
         from the first payment which would otherwise be made in respect of the
         First Contingent Payment.

         (f)      Second Contingent Payments.

                  (i) For each of the first two years after the Closing Date,
         Purchaser will make a payment (a "Second Contingent Payment") to Seller
         in an amount equal to such year's Base Business Ratio (as defined
         below), multiplied by $1,500,000.

                  (ii) The Base Business Ratio for the first year shall be
         determined as follows: If the quotient (the "Quotient") of (i) Base Net
         Sales (as hereinafter defined) in such year, divided by (ii)
         $7,500,000, is at least equal to one, the Base Business Ratio for such
         year is the Quotient. If the Quotient is less than one, the Base
         Business Ratio for such year is the Quotient squared (the Quotient
         times the Quotient).

                  (iii) The Base Business Ratio for the second year shall be
         determined as follows: If the quotient (the "Quotient") of (i) Base Net
         Sales (as hereinafter defined) in such year, divided by (ii)
         $8,400,000, is at least equal to one, the Base Business Ratio for such
         year is the Quotient. If the Quotient is less than one, the Base
         Business Ratio for such year is the Quotient squared.

                  (iv) The term "Base Net Sales" means sales of Products through
         the Base Business, net of returns, discounts and allowances consistent
         with past practice; provided that during periods in which the Company
         does not engage in the Base Business, the term "Base Net Sales" shall
         mean sales of Products through the Base Arms Business, net of returns,
         discounts and allowances consistent with past practice.

                  (v) If during the first two years after the Closing Purchaser
         records revenues from the sale of Products through mass consumer
         markets (i.e., grocery, drug, discount, and other retail outlets with
         "shelves," etc.) ("Additional Net Sales") and such Additional Net Sales
         are not included in the term "Base Net Sales" because Purchaser has not
         theretofore at its discretion terminated on-air sales over television
         shopping networks as a channel for the sale of Products, then such
         Additional Net Sales shall nevertheless be included in the calculation
         of Base Net Sales for the applicable year, but only to the extent that
         the Base Business Ratio as calculated in strict accordance with
         Sections 2(f)(ii) or 2(f)(iii) above would otherwise be less than 1.00.
         For such purpose, the Base Business Ratio will be calculated including
         Additional Net Sales in the numerator of the ratio, but in no event
         shall the Base Business Ratio exceed 1.00.

                                       6

                  (vi) By way of example, assume that Base Net Sales during the
         first year are $13,000,000 and during the second year are $7,000,000.
         The Quotient for the first year would be 1.7333 and the Quotient for
         the second year would be .8333. The Second Contingent Payment for the
         first year would be 1.7333 times $1,500,000, or $2,599,950. The Second
         Contingent Payment for the second year would be 0.6943 (.8333 squared)
         times $1,500,000, or $1,041,450. If, however, Purchaser records
         Additional Net Sales of $2,000,000 in the second year of this example
         and the Additional Net Sales are not included in the term "Base Net
         Sales," then the full $2,000,000 Additional Net Sales would be added to
         the $7,000,000 and the resulting $9,000,000 total would then be divided
         by $8,400,000 yielding a quotient in excess of 1.00 (of which the
         excess over 1.0 is disregarded) and a Second Contingent Payment of
         $1,5000,000.

                  (vii) A "year" for the purpose of this Section is each of the
         successive 12-month periods beginning on the first day of the first
         month which begins after the Closing Date.

                  (viii) The amount of each Second Contingent Payment shall be
         determined by Purchaser's chief financial officer subject to the
         provisions of Section 3. Within 30 days after the final determination
         of a Second Contingent Payment, Purchaser shall make such payment by
         issuing to Seller and its Designees one share of 5% Series G Preferred
         Stock of Purchaser (the "Preferred Stock") for each full $1,000 payable
         in respect of the Second Contingent Payment, together with a cash
         payment for any fractional share which would otherwise be issued
         hereunder. The Certificate of Amendment of Purchaser's Certificate of
         Incorporation in respect of the Preferred Stock shall be in the form of
         Exhibit B to this Agreement.

         (g)      Third Contingent Payment.

                  (i) Purchaser will pay to Seller $1,000,000 (the "Third
         Contingent Payment") within 30 days after the end of the first 12
         consecutive month period which ends before the fifth anniversary of the
         Closing during which:

                  (1)      net sales of the Products in "mass consumer markets"
                           (i.e., grocery, drug, discount, and other retail
                           outlets with "shelves", etc.) are equal to or exceed
                           net on-air sales of the Products on the QVC
                           television network during such 12-month period, and

                  (2)      net on-air sales of the Products on the QVC
                           television network or any other television channel
                           are at least equal to such net sales in the 12
                           consecutive whole calendar months prior to the
                           Closing.

         (h)      Imputed Interest Gross-up. To the extent that Seller shall
                  incur federal and state income tax based on imputed interest
                  on any portion of the Purchase Price paid after the Closing,
                  Purchaser shall gross up such payments in order to make Seller
                  whole in respect of the tax rate differential applicable to
                  ordinary income versus capital gain.

         (i)      The Purchase Price shall be allocated among the Seller's
                  Assets as set forth on Schedule 2(i) to this Agreement, and
                  the parties agree to report this transaction in all required
                  filings and reports to taxing authorities in accordance with
                  said allocation.

3.       Financial Reports, Audit Rights, Non-Circumvention.

         (a)      During the period beginning on the Closing Date and ending
                  upon the earlier of the Third Contingent Payment or the fifth
                  anniversary of the Closing (the "Contingent Payment Period"),
                  Purchaser shall make available to Seller and its
                  representatives: (i) copies of Purchaser's annual and
                  quarterly reports to the SEC within a reasonable time after
                  such reports are filed; and (ii) within 45 days after the end
                  of each quarter, detailed information regarding the number and
                  type of Products sold during the preceding quarter.

         (b)      Seller or its representative will have the right at Seller's
                  expense reasonably to audit Purchaser's records which are
                  relevant to Purchaser's obligations to make payments under
                  Section 2.

         (c)      If there is a dispute between Seller and Purchaser as to the
                  determination of any portion of the Purchase Price, the
                  undisputed portion (if any) shall be paid promptly as provided
                  in Section 2, and the dispute shall be submitted to Price
                  Waterhouse Coopers, which shall review Purchaser's books and
                  records and make a final determination within 30 days. The
                  determination of Price Waterhouse Coopers shall be final and
                  binding on all parties. The fees of Price Waterhouse Coopers
                  shall be paid (i) by Purchaser, if such firm determines that
                  Purchaser underpaid Seller by 3% or more, (ii) by Seller, if
                  such firm determines that Purchaser overpaid Seller by 3% or
                  more, and (iii) equally by Purchaser and Seller in all other
                  cases.

         (d)      Payments under Section 2 which are not made when due shall
                  accrue interest at the lesser of (i) 3.5 points over the
                  "Prime Rate" (as quoted in the Wall Street Journal) or (ii)
                  the highest rate permitted by law.

         (e)      During the Contingent Payment Period, Purchaser shall not take
                  actions which are designed to reduce payments to Seller
                  hereunder unless such actions are primarily intended to
                  benefit Purchaser economically other than by merely reducing
                  such payments to Seller.

4.       Assumption of Certain Liabilities.

         (a)      Purchaser will at the Closing assume the liabilities of Seller
                  which are referred to in Seller's disclosure schedule
                  ("Seller's Disclosure Schedule" or "Disclosure Schedule") as
                  "Assumed Liabilities." Purchaser is not assuming any
                  liabilities of Shareholders.

         (b)      Anything in this Agreement to the contrary notwithstanding,
                  Purchaser shall not assume, or in any way be liable or
                  responsible for:

                  (i) any liability under any contracts which arises out of
         Seller's failure to perform its obligations thereunder to the extent
         such performance is due on or prior to the Effective Date;

                  (ii) any liabilities or obligations for any foreign, federal,
         state, county or local income, franchise, gross receipts or value added
         taxes, or any interest, additions to tax or penalties thereon, accrued
         for, applicable to or arising from any period prior to the Effective
         Date;


                                       8
<PAGE>

                  (iii) any liability or obligation arising in connection with
         Excluded Assets or the operation thereof;

                  (iv) any liability to the extent covered by insurance of
         Seller pursuant to a policy in effect on or prior to Closing; or

                  (v) any profit sharing or incentive bonuses or sales
         commissions or similar bonuses or payments (including, without
         limitation, the liability in the amount of $61,353 to Marvin Segel
         which is reflected on the December Balance Sheet as a Non-Assumed
         Commission Payable, and any other profit sharing or incentive bonuses,
         or sales commissions or similar bonuses or payments to Marvin Segel )
         allocable to the period prior to the Effective Date, it being
         understood that where such bonuses or payments are measured by results
         during a period which straddles the Effective Date, the amount of such
         bonus or payment shall be allocated to the periods before and after the
         Effective Date on a pro rata basis based on the number of days in such
         period before and after the Effective Date, and an estimate of the
         amount due for the period through the Effective Date shall be paid by
         Seller at the Effective Date; or

                  (vi) any payments to employees or others under
         incentive/profit sharing arrangements; or

                  (vii) liabilities reflected on the December Balance Sheet as
         "Non-Assumed Accounts Payable."

5.       Securities Covenants, Lock-Ups and Registration Rights.

         (a)      Seller covenants that at the Closing each of Seller and its
                  Designees shall deliver to Purchaser a certificate in form
                  reasonably satisfactory to Purchaser in which it absolutely
                  and unconditionally represents and warrants to Purchaser that:

                  (i) It will acquire the shares of Common Stock and Preferred
         Shares issuable hereunder, and the shares of common stock issuable on
         conversion of the Preferred Stock (collectively, the "Shares") only for
         its own account, for investment, and without a view to the distribution
         thereof (except in compliance with applicable securities laws).

                  (ii) It understands that it may sell or otherwise transfer the
         Shares only if such transaction is duly registered under the Securities
         Act of 1933, as amended (the "Act"), or an exemption from such
         registration is available. It has been advised or is aware of the
         provisions of Rule 144 promulgated under the Act, which permits limited
         resale of shares purchased in a private placement subject to the
         satisfaction of certain conditions, including, among other things, (1)
         the availability of certain current public information about the
         Purchaser, (2) the passage of required holding periods under Rule 144
         and (3) compliance with limitations on the volume of shares which may
         be sold during any three-month period.

                  (iii) It acknowledges that the certificates representing the
         Shares will be legended to reflect these restrictions.


                                       9
<PAGE>

         (b)      Without limiting Purchaser's other rights or remedies which
                  shall arise out of any breach of the aforesaid covenant, no
                  certificates for the Shares will be delivered if any of Seller
                  or its Designees fails to confirm the foregoing
                  representations as of the Closing.

         (c)      Seller will not, and will cause its Designees not to: (1) sell
                  or otherwise dispose of the shares of common stock issued at
                  Closing for a period of six months from and after the Closing;
                  (2) sell the common stock issued in respect of the First
                  Contingent Payment for a period of six months from and after
                  the date of such First Contingent Payment; or (3) convert the
                  Preferred Stock into common stock during the first six months
                  after the issuance of the Preferred Stock. No restriction is
                  imposed by this Section 5(d) on the sale of any shares of
                  common stock which are issued upon conversion of the Preferred
                  Stock, to the extent such sale is otherwise permitted
                  hereunder. Certificates for the Shares shall be legended to
                  reflect the provisions of this Section.

         (d)      Registration Rights.

                  (i) Purchaser will on or before the 45th day after the Closing
         file a registration statement with the Securities and Exchange
         Commission (the "SEC") for the public sale by the Seller and its
         Designees of the shares of Common Stock issued to Seller and its
         Designees at the Closing. Purchaser will also on or before the 90th day
         after the issuance of the Preferred Stock file a registration statement
         with the Securities and Exchange Commission (the "SEC") for the public
         sale by the Seller and its Designees of the shares of Common Stock
         issuable on conversion of the Preferred Stock. The term "Registration
         Statement" means each registration statement referred to in this
         Section.

                  (ii) If Purchaser shall at any time propose the registration
         under the Act of any shares of common stock, Purchaser shall give
         notice as promptly as possible (but no less than 15 days before filing
         a registration statement with respect to such registration) of such
         proposed registration to Seller, and Purchaser shall use its best
         efforts to include in such registration statement such number of shares
         of common stock as Seller and its Designees shall request within 10
         days after the receipt of such notice to be included in any such
         offering; provided, however, that

                  (1)      Purchaser 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;

                  (2)      Purchaser shall not be required to include such
                           shares in any such registration if Purchaser 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 Purchaser,
                           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

                           withdraw such registration statement and abandon the
                           proposed offering in which Seller had requested to
                           participate.

                  (iii) Purchaser shall use commercially reasonable efforts to
         cause the Registration Statement to become effective not later than 60
         days after the date of filing, and to remain effective for two years.
         The registration shall be accompanied by blue sky clearances in such
         states as Seller and its Designees may reasonably request and in which
         there is no applicable exemption from the requirement to register.

                  (iv) Purchaser shall pay all expenses of the registration
         hereunder including reasonable fees of any one law firm which alone
         represents Seller and all of its Designees, but Purchaser shall not pay
         Seller's underwriting discounts.

                  (v) Purchaser shall supply to Seller and its Designees a
         reasonable number of copies of all registration materials and
         prospectuses. Purchaser and Seller shall execute and deliver to each
         other indemnity agreements which are set forth in Schedule 5(d)(v). The
         Shareholders shall reasonably cooperate with Purchaser in the
         preparation and filing of the Registration Statement and appropriate
         amendments thereto.

                  (vi) Whether or not any shares have been registered, neither
         Seller nor either Shareholder shall engage (or cause others, including
         without limitation Seller's employees, to engage) in the trading of
         securities of Purchaser prior to the Closing.

                  confirmation and take such action as Purchaser may reasonably
                  deem necessary or desirable in order to more effectively

                  Seller and each Shareholder agree that after the Closing, each
                  will execute any documents which may be required to vest all

                  in the Intangible Property.

                  notice, Seller shall have access to the books and records
                  included in the Seller's Assets, and Purchaser shall have
                  access to Seller's books and records for the period prior to
                  the Closing to the extent that the same are not included in
                  Seller's Assets, and Purchaser shall have the right at its
                  expense to make copies of any of such records. Each party
                  shall retain such books and records for a period of not less
                  than three years after the Closing, and shall not dispose of

                  Purchaser as provided herein and to endorse with the name of
                  Seller any checks received on account of any such receivables
                  or other items. Seller agrees that it will promptly transfer
                  and deliver to Purchaser any cash or other property which
                  Seller may receive in respect of such receivables or other
                  items.

8.   Board Position. So long as Seller and the Shareholders own more than 10% of
     the total number of outstanding shares of Common Stock (including in such
     calculation that number of shares of Common Stock into which Preferred
     Stock held by Seller and the Shareholders is convertible), Seller and the
     Shareholders shall have the right jointly to nominate one member of
     Purchaser's Board of Directors, subject to Purchaser's approval, which will
     not be unreasonably withheld. Purchaser shall in Purchaser's annual proxy
     statement to its shareholders submit such nominee to Purchaser's
     shareholders for election as a management nominee.

     non-exclusive, fully paid-up license in the form of Exhibit F to use the
     name "Optimum Lifestyle" for a one-year period beginning on the Closing

     trademark for "Optimum Lifestyle" to be cancelled, and that in any event
     Seller will not use such term as a trademark or in connection with the
     dietary supplement or nutrition food products business.

     forth in the Disclosure Schedule with respect to specifically identified
     subsections of this Section 10 or except where a disclosure with respect to
     a specifically identified subsection manifestly is also an exception to
     another one or more subsections, Seller and each Shareholder jointly and
     severally represent and warrant to Purchaser as follows:

                  properties; and it is duly qualified, licensed or domesticated
                  and in good standing as a foreign corporation authorized to do
                  business in the states listed on Seller's Disclosure Schedule,
                  which are the only states where the nature of the activities
                  conducted by it or the character of the properties owned,
                  leased or operated by it require such qualification, licensing
                  or domestication and where the failure to be so qualified
                  would cause a material adverse effect on Seller's business.

         (b)      Subsidiaries. Seller has no subsidiaries. Seller has no
                  interest, direct or indirect, and has no commitment to
                  purchase any interest, direct or indirect, in any other
                  corporation or in any partnership, joint venture or other
                  business enterprise or entity. The business carried on by
                  Seller has not been conducted through any other direct or
                  indirect subsidiary or affiliate of any Shareholder.

         (c)      Transactions with Certain Persons.

                  (i) During the past three years Seller has not, directly or
         indirectly, purchased, leased from others or otherwise acquired any
         property or obtained any services from, or sold, leased to others or

         course of business or otherwise, (i) any shareholder of Seller or (ii)
         any person, firm or corporation which, directly or indirectly, alone or
         together with others, controls, is controlled by or is under common
         control with Seller or any shareholder of Seller.

                  (ii) Seller does not owe any amount to, or have any contract
         with or commitment to, any of its shareholders, directors, officers,
         employees or consultants (other than compensation for current services
         not yet due and payable and reimbursement of expenses arising in the
         ordinary course of business), and none of such persons owes any amount
         to Seller.

                  (iii) Seller does not use any property or assets of any
         Shareholder or any direct or indirect subsidiary or affiliate of any
         Shareholder.

                  Neither the execution, delivery nor performance of this
                  Agreement by Seller or any Shareholder will, with or without
                  the giving of notice or the passage of time, or both, conflict
                  with, result in a default, right to accelerate or loss of
                  rights under, or result in the creation of any lien, charge or
                  encumbrance pursuant to, any provision of Seller's articles of
                  incorporation or by laws or any franchise, mortgage, deed of
                  trust, lease, license, agreement, understanding, law, rule or
                  regulation or any order, judgment or decree to which Seller or
                  any Shareholder is a party or by which any of them may be
                  bound or affected. Seller and each Shareholder have the full
                  power and authority to enter into this Agreement and to carry
                  out the transactions contemplated hereby, all proceedings
                  required to be taken by them or its shareholders to authorize

                  this Agreement constitutes a valid and binding obligation of
                  Seller and each Shareholder.

                  beneficially 50% of the authorized, issued and outstanding
                  shares of capital stock of Seller, free and clear of any
                  liens, claims, encumbrances or restrictions of any kind, and

         collectively called the "Financial Statements") which are attached as
         Exhibit G have been prepared from the books and records of Seller in
         accordance with accounting principles which have been consistently

         operations for the periods covered thereby.

                  (iii) The statements of earnings included in the Financial
         Statements do not contain any items of special or nonrecurring income

                  on the December Balance Sheet date or any other debts,
                  liabilities or obligations relating to or arising out of any
                  act, transaction, circumstance or state of facts which
                  occurred or existed on or before the December Balance Sheet
                  Date, whether or not then known, due or payable.

                  country, or by any other taxing authority, which are due or
                  payable by Seller, and all interest and penalties thereon,
                  whether disputed or not, have been paid in full . All deposits
                  required by law to be made by Seller with respect to
                  employees' withholding taxes have been duly made. Seller has
                  not been delinquent in the payment of any foreign or domestic
                  tax, assessment or governmental charge or deposit and has no
                  tax deficiency or claim outstanding, proposed or assessed
                  against it, and there is no basis for any such deficiency or
                  claim. The audit status of Seller's federal income tax returns
                  is as set forth in the Disclosure Schedule, and there is not
                  now in force any extension of time with respect to the date on
                  which any tax return was or is due to be filed by or with
                  respect to Seller, or any waiver or agreement by it for the
                  extension of time for the assessment of any tax.

         (i)      Absence of Changes or Events. Since the December Balance Sheet
                  Date, Seller has conducted its business only in the ordinary
                  course and has not:

                  (1)      incurred any obligation or liability, absolute,
                           accrued, contingent or otherwise, whether due or to

                           business obligations incurred in the ordinary course
                           of business and consistent with its prior practice,
                           none of which liabilities, in any case or in the
                           aggregate, materially and adversely affects the
                           business, liabilities or financial condition of
                           Seller;

                           discharged or satisfied, or paid any obligation or
                           liability, absolute, accrued, contingent or
                           otherwise, whether due or to become due, other than
                           current liabilities shown on the December Balance
                           Sheet and current liabilities incurred since the
                           December Balance Sheet Date in the ordinary course of
                           business and consistent with its prior practice;

                  (3)      except for the Pre-Closing Dividend, declared or made
                           any payment of dividends or other distribution to its
                           shareholders or upon or in respect of any shares of
                           its capital stock, or purchased, retired or redeemed,
                           or obligated itself to purchase, retire or redeem,
                           any of its shares of capital stock or other
                           securities;

                  (4)      mortgaged, pledged or subjected to lien, charge,
                           security interest or any other encumbrance or

                           tangible or intangible;

                           transferred, leased to others or otherwise disposed
                           of any of its assets, except for inventory sold in
                           the ordinary course of business, or canceled or
                           compromised any debt or claim, or waived or released
                           any right of substantial value;

                           has had or may have a materially adverse effect on

                  existing laws, rules, regulations, ordinances, orders,
                  judgments and decrees applicable to its business, properties
                  or operations as presently conducted, including without

                  authorizations applicable to its business, properties or

                  and the Shareholders, neither the ownership nor use of
                  Seller's properties nor the conduct of its business as
                  currently conducted conflicts with the rights of any other

                  lease, license, agreement, understanding, law, ordinance, rule
                  or regulation, or any order, judgment or decree to which
                  Seller is a party or by which it may be bound or affected; and
                  Seller is not aware of any proposed laws, rules, regulations,
                  ordinances, orders, judgments, decrees, governmental takings,
                  condemnations or other proceedings which would be applicable
                  to its business, operations or properties and which might
                  adversely affect its properties, assets, liabilities,
                  operations or prospects, either before or after the Closing.

         Seller's Assets and those assets and properties which are reflected in
         the December Balance Sheet (except inventory sold after the December

         immediately prior to the Closing, the Pre-Closing Dividend).

                  (ii) None of such properties and assets is subject to any
         mortgage, pledge, lien, charge, security interest, encumbrance,

         any nature whatsoever, direct or indirect, whether accrued, absolute,
         contingent or otherwise, except:

                  (1)      as expressly set forth in the December Balance Sheet
                           or in the Disclosure Schedule as securing specific
                           liabilities or as otherwise expressly permitted by

                                    extent and do not materially detract from
                                    the value of the properties subject thereto,

                           (b)      do not interfere with either the present and
                                    continued use of such property or the

                           (c)      have arisen only in the ordinary course
                                    of business.

                           relate to Seller's Assets (pursuant to license

                  (2)      all applications for and registrations of Proprietary
                           Rights and the jurisdictions in which the Proprietary

                           the Proprietary Rights; and

                  (4)      all inventions and technology used by or possessed by
                           Seller, including, but not limited to, manufacturing
                           information, know-how and processes, quality control

                  (ii) Seller has not received notice of any claims or demands
         of any person pertaining to the Proprietary Rights or the Trade Secrets
         or the rights of Seller thereunder, and to the knowledge of Seller or
         any Shareholder, no proceedings have been instituted or are pending or
         threatened which challenge the rights of Seller in respect thereof. To
         the knowledge of Seller and Shareholders none of the issued trademarks,
         service marks, trade names, trade dress, label filings, patents,
         copyrights, logos, registrations thereof, or, as the case may be, the
         rights granted to Seller in respect thereof and to be listed in
         Seller's Disclosure Schedule, infringes on or is being infringed upon
         by others, and none is subject to any outstanding order, decree,
         judgment, stipulation, injunction, restriction or agreement restricting
         the scope of the use by Seller.

                  (iii) To the knowledge of Seller and Shareholders, Seller is

         of any former employer of any employee of Seller.

                  (iv) Seller and Shareholders have no knowledge of any patented
         device or application therefor owned or held by others which could
         materially and adversely affect the operation of the businesses of
         Seller, as now conducted.

                  (v) The Trade Secrets have not been, and will not be,
         disclosed by Seller to any person other than Purchaser and its agents
         and representatives, and comprise all of the same necessary to permit
         the continued operation of the business of Seller.

         (o)      No Guaranties. None of the obligations or liabilities of
                  Seller is guaranteed by any other person, firm or corporation,
                  nor has Seller guaranteed the obligations or liabilities of
                  any other person, firm or corporation.

         (p)      Inventory. All items of Seller's inventory and related
                  supplies (including raw materials, work-in-process and
                  finished goods) reflected on the December Balance Sheet or
                  thereafter acquired and not subsequently disposed of in the
                  ordinary course of business ( except for obsolete items and
                  items of below-standard quality, all of which have been
                  written off or written down in value as reflected on the
                  December Balance Sheet or which have not been written off or
                  written down but are reflected on the December Balance Sheet
                  at an aggregate of no more than $50,000) are merchantable, or
                  suitable and usable


                                       21

                  for the production or completion of merchantable products, for
                  sale in the ordinary course of business as first quality goods
                  at normal mark-ups, none of such items is obsolete or below
                  standard quality and each item of such inventory reflected in
                  the December Balance Sheet and the books and records of Seller
                  is so reflected on the basis of a complete physical count and
                  is valued at the lower of cost (on a first-in, first-out
                  basis) or market in accordance with generally accepted
                  accounting principles consistently applied. Seller's Assets
                  include a sufficient but not an excessive quantity of each
                  type of such inventory and supplies in order to meet the
                  normal requirements of Seller's business.

         (q)      Receivables. All receivables of Seller (including accounts
                  receivable, loans receivable and advances) which are reflected
                  in the December Balance Sheet, and all such receivables which
                  will have arisen since the date thereof, shall have arisen
                  only from bona fide transactions in the ordinary course of
                  Seller's business.

         (r)      Labor Matters. Seller is not a party to any collective
                  bargaining agreement and there are no material or formal
                  complaints, charges, cases or controversies or any
                  conciliation agreement, consent or decree pending or, to the
                  knowledge of Seller or Shareholders, threatened against Seller
                  and any of its employees acting individually or in concert and
                  to the knowledge of Seller and Shareholders no organization is
                  presently attempting to gain, petitioning for or asserting
                  representational status with respect to any group or groups of
                  employees of Seller, and Seller is in material compliance with
                  Federal and state laws respecting employment practices, terms
                  and conditions of employment, wages and hours, and is not
                  presently engaged in any unfair labor practice. All employees
                  of the Company are legally employed, and those who are not
                  U.S. citizens have appropriate U.S. governmental
                  authorizations. There is no labor strike or other labor
                  dispute and there is no complaint, proceeding or other action
                  instituted under the Equal Opportunity Act pending or, to the
                  knowledge of Seller or Shareholders, threatened against
                  Seller.

         (s)      Environmental Matters.

                  (i) Seller is, and at all times has been, in material
         compliance with, and has not been in violation of, any federal, state,
         foreign, or local laws, statutes, ordinances, regulations, rules and
         orders pertaining to the environment, pollution and/or the health and
         safety of human beings (collectively "Environmental Law"). Neither
         Shareholder nor Seller has any basis to expect or has received, any
         actual or threatened order, notice, or other communication from (A) any
         governmental body or private citizen acting in the public interest, or
         (B) the current or prior owner or operator of any facilities, of any
         actual or potential violation or failure to comply with any
         Environmental Law with respect to any of the properties or assets
         (whether real, personal, or mixed) in which Seller has or has had an
         interest, or with respect to any property at or to which any hazardous
         or toxic waste or substance ("Hazardous Materials") was generated,
         manufactured, refined, transferred, imported, used, or processed by
         Seller, or from which Hazardous Materials have been transported,
         treated, stored, handled, transferred, disposed, recycled, or received.

                  (ii) To the knowledge of Seller and Shareholders, there are no
         pending or threatened claims, encumbrances, or other restrictions of
         any nature, resulting from any environmental, health, and safety
         liabilities or arising under or pursuant to any Environmental Law, with
         respect to or affecting any of the facilities or any other



                                       22
<PAGE>

         properties and assets (whether real personal or mixed) in which Seller
         has or had an interest.

                  (iii) Neither Shareholder nor Seller has permitted or
         conducted, or is aware of, any Hazardous Materials activity conducted
         with respect to the properties or assets (whether real, personal, or
         mixed) in which Seller has or had an interest.

                  (iv) To the knowledge of Seller and the Shareholders, there
         has been no release or threat of release of any Hazardous Materials at
         or from the locations where any Hazardous Materials were generated,
         manufactured, refined, transferred, produced, imported, used or
         processed from or by the properties and assets (whether real, personal,
         or mixed) in which Seller has or had an interest.

                  (v) Seller has delivered to Purchaser true and complete copies
         and results of any reports, studies, analyses, tests, or monitoring
         possessed or initiated by Seller pertaining to Hazardous Materials or
         Hazardous Materials activities in, on, or under the properties of
         Seller, or concerning compliance by Seller with respect to
         Environmental Laws.

         (t)      Proceedings re Employee Benefit Plans. There has not been any
                  (i) termination of any "defined benefit plan" within the
                  meaning of the Employee Retirement Income Security Act of l974
                  ("ERISA") maintained by Seller or any person, firm or
                  corporation ("Affiliate") which is under "common control"
                  (within the meaning of Section 4001(b) of ERISA) with Seller,
                  or (ii) commencement of any proceeding to terminate any such
                  plan pursuant to ERISA, or otherwise or (iii) written notice
                  given to Seller or any Affiliate of the intention to commence
                  or seek the commencement of any such proceeding. All accrued
                  benefits under each pension plan of Seller covering employees
                  who are to be transferred to the employ of Purchaser following
                  the Closing ("Transferred Employees") shall be fully provided
                  for as of the date of the Closing by any one or more of (i)
                  annuity contracts for the benefit of such Transferred
                  Employees issued by an insurance company acceptable to
                  Purchaser, (ii) the transfer to a successor plan established
                  or maintained by Purchaser for the benefit of such Transferred
                  Employees of assets having a fair market value of not less
                  than the present value of all such accrued benefits, (iii) in
                  the case of any multi-employer plan or any single employer
                  plan which Purchaser shall assume, by the fair market value of
                  the assets of such plan as of the date of the Closing being
                  not less than the present value of all accrued benefits under
                  such plan at such date and/or (iv) the termination of such
                  plan and the distribution of total account balances to
                  participants. Seller has no knowledge or information of any
                  planned or required increase in the level of contributions or
                  benefits under any such pension plan, or of any circumstances
                  which would suggest that such an increase may be required, or
                  that any union representing employees covered under any such
                  plan will attempt to negotiate for such an increase. In the
                  case of each pension plan to which Seller makes contributions
                  on behalf of Transferred Employees under which contributions
                  are fixed pursuant to a collective bargaining agreement, the
                  level of contributions currently provided for in the
                  applicable collective bargaining agreement is sufficient to
                  meet the funding requirements of ERISA applicable to such
                  plan, based on Acceptable Actuarial Assumptions. Each funded
                  pension plan maintained by Seller for one or more Transferred
                  Employees constitutes a qualified plan under section 40l(a) of
                  the Internal Revenue Code of l954 and meets all applicable
                  requirements of ERISA.

         (u)      Absence of Certain Business Practices. Neither Seller nor
                  either Shareholder, nor any other person acting on its or
                  their behalf, has, directly or indirectly, within the past
                  three years given or agreed to give any gift or similar
                  benefit, to any customer, supplier, governmental employee or
                  other person who is or may be in a position to help or hinder
                  the business of Seller (or assist Seller in connection with
                  any actual or proposed transaction) which (i) might subject
                  Seller to any damage or penalty in any civil, criminal or
                  governmental litigation or proceeding, (ii), if not given in
                  the past, might have had an adverse effect on the assets,
                  business or operations of Seller as reflected in the Financial
                  Statements or (iii), if not continued in the future, might
                  adversely affect Seller's assets, business, operations or
                  prospects or which might subject Seller to suit or penalty in
                  any private or governmental litigation or proceeding.

         (v)      Certain Representations

                  (i) To the knowledge of Seller and Shareholders, no supplier
         or customer is considering termination, non-renewal or adverse
         modification of its agreements or arrangements with Seller and the
         transactions contemplated by this Agreement will not have a material
         adverse effect on Seller's relationships with its suppliers and
         customers. In particular, Seller's representative has notified
         Shareholders that QVC intends to increase both the quantity and quality
         of air time in 1999 as compared to 1998.

                  (ii) Within the past three years, Seller has not entered into
         any agreement with, or been investigated by, any governmental
         authority, community group or other third party that could restrict the
         operation of its business.

                  (iii) No Key Employee of Seller has indicated to either
         Shareholder that he or she is considering terminating his or her
         employment.

                  (iv) No shareholder has any direct or indirect interest of any
         kind in any business or entity which is competitive with Seller.

         (w)      Disclosure. No representation or warranty by Seller or any
                  Shareholder contained in this Agreement nor any statement or
                  certificate furnished or to be furnished by Seller or any
                  Shareholder to Purchaser or its representatives in connection
                  herewith or pursuant hereto contains or will contain any
                  untrue statement of a material fact, or omits or will omit to
                  state any material fact, in light of the circumstances when
                  made, required to make the statements herein or therein
                  contained not misleading. The representations and warranties
                  contained in this Section 10 shall not be affected or deemed
                  waived by reason of the fact that Purchaser and/or its
                  representatives knew or should have known that any such
                  representation or warranty is or might be inaccurate in any
                  respect, but any such representation or warranty shall be
                  deemed waived if Seller clearly and unambiguously demonstrates
                  that Purchaser's officers prior to the date of this Agreement
                  had actual knowledge that such representation or warranty was
                  inaccurate.

11.  Representations and Warranties by Purchaser. Purchaser represents and
     warrants to Seller and the Shareholders as follows:

         (a)      Organization. Purchaser is a corporation duly organized,
                  validly existing and in good standing under the laws of New
                  York and has full corporate power and authority to carry on
                  its business as now being conducted and to own, lease or
                  operate its properties.

         (b)      Authorization and Approval of Agreement. All proceedings or
                  corporate action required to be taken by Purchaser relating to
                  the execution and delivery of this Agreement and the
                  consummation of the transactions contemplated hereby shall
                  have been taken.

         (c)      Execution, Delivery and Performance of Agreement. Neither the
                  execution, delivery nor performance of this Agreement by
                  Purchaser will, with or without the giving of notice or the
                  passage of time, or both, conflict with, result in a default,
                  right to accelerate or loss of rights under, or result in the
                  creation of any lien, charge or encumbrance pursuant to, any
                  provision of Purchaser's certificate of incorporation or
                  by-laws or any franchise, mortgage, deed of trust, lease,
                  license, agreement, understanding, law, ordinance, rule or
                  regulation or any order, judgment or decree to which Purchaser
                  is a party or by which it may be bound or affected. Purchaser
                  has full power and authority to enter into this Agreement and
                  to carry out the transactions contemplated hereby, all
                  proceedings required to be taken by Purchaser to authorize the
                  execution, delivery and performance of this Agreement and the
                  agreements relating hereto have been properly taken and this
                  Agreement constitutes a valid and binding obligation of
                  Purchaser.

         (d)      Litigation. There is no legal action, suit, arbitration,
                  governmental investigation or other legal or administrative
                  proceeding, nor any order, decree or judgment in progress,
                  pending or in effect, or to the knowledge of Purchaser
                  threatened, against or relating to Purchaser in connection
                  with or relating to the transactions contemplated by this
                  Agreement or otherwise, that could have a material adverse
                  effect upon Purchaser or its business or financial condition.

         (e)      Reports and Financial Statements.

                  (i) Purchaser has previously furnished to Seller copies of
         Purchaser's (i) Annual Report on Form 10-K/A for the year ended June
         30, 1998, as filed with the SEC (the "Purchaser Annual Report"), (ii)
         Quarterly Report on Form 10-Q filed for the fiscal quarters ended
         September 30, 1998 (the "Purchaser Quarterly Report"), (iii) proxy
         statements relating to all meetings of its stockholders (whether annual
         or special) since December 31, 1996, and (iv) all other reports,
         registration statements and other written materials filed by Purchaser
         with the SEC since December 31, 1996.

                  (ii) The financial statements included in such reports were
         prepared in accordance with generally accepted accounting principles,
         consistently applied, and present fairly the financial position and the
         results of operations of Purchaser for the periods indicated. There has
         been no material adverse change in Purchaser's business or financial
         condition since September 30, 1998.

                  (iii) 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.

         (f)      Capitalization. The capitalization of Purchaser as of
                  September 30, 1998 was as set forth in the Purchaser Quarterly
                  Report. As of June 30, 1998, except as reflected in the
                  Purchaser Annual Report, there were no outstanding
                  subscriptions, options, warrants, calls, contracts, demands,
                  commitments, convertible securities or other agreements or
                  arrangements of any character or nature whatsoever under which
                  Purchaser is or may become to issue, assign or transfer any
                  shares of the capital stock of Purchaser.

         (g)      Absence of Undisclosed Liabilities. Except as and to the
                  extent reflected in the Purchaser Quarterly Report, as of the
                  September 30, 1998, Purchaser had no debts, liabilities or
                  obligations which were not reflected in the Purchaser
                  Quarterly Report and which should have been reflected thereon
                  under GAAP as consistently applied by Purchaser.

         (h)      Taxes. All taxes, including, without limitation, income,
                  property, sales, use, franchise, added value, employees'
                  income withholding and social security taxes, imposed by the
                  United States or by any foreign country or by any state,
                  municipality, subdivision or instrumentality of the United
                  States or of any foreign country, or by any other taxing
                  authority, which are due or payable by Purchaser, and all
                  interest and penalties thereon, whether disputed or not, have
                  been paid in full, all tax returns required to be filed in
                  connection therewith have been accurately prepared and duly
                  and timely filed and all deposits required by law to be made
                  by Purchaser with respect to employees' withholding taxes have
                  been duly made. Purchaser has not been delinquent in the
                  payment of any foreign or domestic tax, assessment or
                  governmental charge or deposit and has no tax deficiency or
                  claim outstanding, proposed or assessed against it, and there
                  is no basis for any such deficiency or claim. The audit status
                  of Purchaser's federal income tax returns is as Purchaser has
                  advised by separate document. There is not now in force any
                  extension of time with respect to the date on which any tax
                  return was or is due to be filed by or with respect to
                  Purchaser, or any waiver or agreement by it for the extension
                  of time for the assessment of any tax.

         (i)      Labor Matters. Purchaser is not a party to any collective
                  bargaining agreement and there are no material or formal
                  complaints, charges, cases or controversies or any
                  conciliation agreement, consent or decree pending or, to the
                  knowledge of Purchaser, threatened against Purchaser and any
                  of its employees acting individually or in concert and to the
                  knowledge of Purchaser no organization is presently attempting
                  to gain, petitioning for or asserting representational status
                  with respect to any group or groups of employees of Purchaser,
                  and Purchaser is in material compliance with Federal and state
                  laws respecting employment practices, terms and conditions of
                  employment, wages and hours, and is not presently engaged in
                  any unfair labor practice. All employees of Purchaser are
                  legally employed, and those who are not U.S. citizens have
                  appropriate U.S. governmental authorizations. There is no
                  labor strike or other labor dispute and there is no complaint,
                  proceeding or other action instituted under the Equal
                  Opportunity Act pending or, to the knowledge of Purchaser,
                  threatened against Purchaser.

         (j)      Environmental Matters.

                  (i) Purchaser is, and at all times has been, in material
         compliance with, and has not been in violation of, any federal, state,
         foreign, or local laws, statutes, ordinances, regulations, rules and
         orders pertaining to the environment, pollution and/or the health and
         safety of human beings (collectively "Environmental Law"). Purchaser
         has no basis to expect or has received, any actual or threatened order,
         notice, or other communication from (i) any governmental body or
         private citizen acting in the public interest, or (ii) the current or
         prior owner or operator of any facilities, of any actual or potential
         violation or failure to comply with any Environmental Law with respect
         to any of the properties or assets (whether real, personal, or mixed)
         in which Purchaser has or has had an interest, or with respect to any
         property at or to which any hazardous or toxic waste or substance
         ("Hazardous Materials") was generated, manufactured, refined,
         transferred, imported, used, or processed by Purchaser, or



                                       26
<PAGE>

         from which Hazardous Materials have been transported, treated, stored,
         handled, transferred, disposed, recycled, or received.

                  (ii) To the knowledge of Purchaser, there are no pending or
         threatened claims, encumbrances, or other restrictions of any nature,
         resulting from any environmental, health, and safety liabilities or
         arising under or pursuant to any Environmental Law, with respect to or
         affecting any of the facilities or any other properties and assets
         (whether real personal or mixed) in which Purchaser has or had an
         interest.

                  (iii) Purchaser has not permitted or conducted, or is aware
         of, any Hazardous Materials activity conducted with respect to the
         properties or assets (whether real, personal, or mixed) in which
         Purchaser has or had an interest. (iv) To the knowledge of Purchaser,
         there has been no release or threat of release of any Hazardous
         Materials at or from the locations where any Hazardous Materials were
         generated, manufactured, refined, transferred, produced, imported, used
         or processed from or by the properties and assets (whether real,
         personal, or mixed) in which Purchaser has or had an interest.

         (k)      Proceedings re Employee Benefit Plans. There has not been any
                  (i) termination of any "defined benefit plan" within the
                  meaning of the Employee Retirement Income Security Act of l974
                  ("ERISA") maintained by Purchaser or any person, firm or
                  corporation ("Affiliate") which is under "common control"
                  (within the meaning of Section 4001(b) of ERISA) with
                  Purchaser, or (ii) commencement of any proceeding to terminate
                  any such plan pursuant to ERISA, or otherwise or (iii) written
                  notice given to Purchaser or any Affiliate of the intention to
                  commence or seek the commencement of any such proceeding.
                  Purchaser has no knowledge or information of any planned or
                  required increase in the level of contributions or benefits
                  under any such pension plan, or of any circumstances which
                  would suggest that such an increase may be required, or that
                  any union representing employees covered under any such plan
                  will attempt to negotiate for such an increase. Each funded
                  pension plan maintained by Purchaser for one or more
                  Transferred Employees constitutes a qualified plan under
                  section 40l(a) of the Internal Revenue Code of l954 and meets
                  all applicable requirements of ERISA.

         (l)      Compliance with Laws and Other Instruments. To the knowledge
                  of Purchaser, Purchaser has complied with all existing laws,
                  rules, regulations, ordinances, orders, judgments and decrees
                  applicable to its business, properties or operations as
                  presently conducted, including without limitation, all federal
                  OSHA and California Department of Health requirements, and has
                  all permits, licenses and other authorizations applicable to
                  its business, properties or operations as presently conducted.
                  To the knowledge of Purchaser, neither the ownership nor use
                  of Purchaser's properties nor the conduct of its business as
                  currently conducted conflicts with the rights of any other
                  person, firm or corporation or violates, or with or without
                  the giving of notice or the passage of time, or both, will
                  violate, conflict with or result in a default, right to
                  accelerate or loss of rights under, any terms or provisions of
                  its certificate of incorporation or bylaws as presently in
                  effect, or any lien, encumbrance, mortgage, deed of trust,
                  lease, license, agreement, understanding, law, ordinance, rule
                  or regulation, or any order, judgment or decree to which
                  Purchaser is a party or by which it may be bound or affected;
                  and Purchaser is not aware of any proposed laws, rules,
                  regulations, ordinances, orders, judgments, decrees,
                  governmental takings, condemnations or other proceedings which
                  would be applicable to 


                                       27
<PAGE>

                  its business, operations or properties and which might
                  adversely affect its properties, assets, liabilities,
                  operations or prospects, either before or after the Closing.

         (m)      Disclosure. No representation or warranty by Purchaser
                  contained in this Agreement nor any statement or certificate
                  furnished or to be furnished by Purchaser to Seller or the
                  Shareholders or their representatives in connection herewith
                  or pursuant hereto contains or will contain any untrue
                  statement of a material fact, or omits or will omit to state
                  any material fact, in light of the circumstances when made,
                  required to make the statements herein or therein contained
                  not misleading. The representations and warranties contained
                  in this Section 11 shall not be affected or deemed waived by
                  reason of the fact that Seller and/or its representatives or
                  the Shareholders knew or should have known that any such
                  representation or warranty is or might be inaccurate in any
                  respect, but any such representation or warranty shall be
                  deemed waived if Purchaser clearly and unambiguously
                  demonstrates that Seller or the Shareholders prior to the date
                  of this Agreement had actual knowledge that such
                  representation or warranty was inaccurate.

                  (b) of this Section have been fulfilled.

         (e)      All agreements, instruments and documents required to be

<PAGE>

                  (v) any and all actions, suits, proceedings, claims, demands,
         assessments, judgments, costs, and expenses, including, without
         limitation, legal fees and expenses, incident to any of the foregoing
         or incurred in investigating or attempting to avoid the same or to
         oppose the imposition of any claims by third parties, or in enforcing
         this indemnity.

         (c)      Indemnity Procedure.

                  (i) In the event any person indemnified under this Section (an
         "Indemnified Party") seeks indemnification pursuant to this Agreement,
         the Indemnified Party shall give prompt notice to the party or parties
         from whom such indemnification is sought (the "Indemnifying Party") of
         the assertion of any claim, or the commencement of any action or
         proceeding, in respect of which indemnity may be sought hereunder.

                  (ii) The Indemnifying Party shall have the right to, and shall
         at the request of the Indemnified Party, assume the defense of any such
         action or proceeding at its own expense.

                  (iii) In any such action or proceeding, the Indemnified Party
         shall have the right to retain its own counsel; but the fees and
         expenses of such counsel shall be at its own expense unless (A) the
         Indemnifying Party and Indemnified Party shall have mutually agreed to
         the retention of such counsel or (B) the named parties to any suit,
         action or proceeding (including any impleaded parties) include both the
         Indemnifying Party and the Indemnified Party and representation of all
         parties by the same counsel would be inappropriate due to actual or
         potential conflicts of interest between them. An Indemnifying Party
         shall not be liable under this Agreement for any settlement effected
         without its consent of any claim, litigation or proceeding in respect
         of which indemnity may be sought hereunder, but such consent shall not
         be unreasonably withheld or delayed.

                  (iv) The Indemnifying Party may settle any claim without the
         consent of the Indemnified Party, but only if the sole relief awarded
         is monetary damages that are paid in full by the Indemnifying Party.

         (d)      The following limitations shall apply to any and all claims
                  for indemnification by any party under this Agreement:

                  (i) The representations and warranties of the parties
         contained in Sections 10 and 11 of this Agreement (including the
         Disclosure Schedule) shall survive the Closing until August 31, 2000,
         provided that if written notice of a claim meeting the requirements of
         this Section has been made during such period, the relevant
         representations shall survive as to such claim until the claim has been
         finally resolved. Notwithstanding the foregoing, the representations
         and warranties set forth in Sections 10(h) and 10(s) shall survive
         until 30 days after the applicable statutes of limitation.

                  (ii) No Indemnified Party listed in Section 15(a) shall be
         entitled to assert any right to indemnification hereunder unless and
         until the aggregate of all claims for indemnification equals or exceeds
         $75,000. Once such claims equal or exceed the $75,000 threshold, such
         Indemnified Party shall be entitled to the full amount of all
         indemnified claims in excess of such threshold; provided that no claim
         for 


                                       31


<PAGE>



         indemnification hereunder may be asserted by an indemnified party
         unless such claim (or series of related claims) equals or exceeds
         $5,000 individually.

                  (iii) No Indemnified Party listed in Section 15(b) shall be
         entitled to assert any right to indemnification hereunder unless and
         until the aggregate of all claims for indemnification equals or exceeds
         $75,000. Once such claims equal or exceed the $75,000 threshold, such
         Indemnified Party shall be entitled to the full amount of all
         indemnified claims in excess of such threshold; provided that no claim
         for indemnification hereunder may be asserted by an indemnified party
         unless such claim (or series of related claims) equals or exceeds
         $5,000 individually.


Except in the case of fraud or intentional misrepresentations, the aggregate
liability under this Section 15 of Seller and the Shareholders shall not at any
time exceed an amount equal to (1) 30% of the initial or current value
(whichever is greater) of all cash and Common Stock theretofore paid by
Purchaser to Seller and Seller's Designees, plus (2) a 100% offset against all
payments which might otherwise subsequently become payable to Seller under
Section 2.

16.      Bulk Sales Compliance. Purchaser hereby waives compliance by Seller
         with the provisions of the Bulk Sales Law of any state, and Seller
         warrants and agrees to pay and discharge when due all claims of
         creditors which could be asserted against Purchaser by reason of such
         non-compliance to the extent that such liabilities are not specifically
         assumed by Purchaser under this Agreement. Seller and each of the
         Shareholders, jointly and severally hereby indemnify and agree to hold
         Purchaser harmless from, against and in respect of (and shall on demand
         reimburse Purchaser for) any loss, liability, cost or expense,
         including, without limitation, attorneys' fees, suffered or incurred by
         Purchaser by reason of the failure of Seller to pay or discharge such
         claims.

17.      Termination. This Agreement may, by notice given prior to the Closing,
         be terminated:

         (a)      by Purchaser if a material breach of any provision of this
                  Agreement has been committed by Seller or the Shareholders and
                  such breach has not been waived;

         (b)      by Seller if material breach of any provision of this
                  Agreement has been committed by Purchaser and such breach has
                  note been waived;

         (c)      by Purchaser if any condition in Section 13 has not been
                  satisfied as of the Closing Date and Purchaser has not waived
                  such condition on or before the Closing Date;

         (d)      by Seller if any condition in Section 14 has not been
                  satisfied as of the Closing Date and Seller has not waived
                  such condition on or before the Closing Date;

         (e)      by mutual consent of the parties; or

         (f)      by either Purchaser or Seller if the Closing has not occurred
                  (other than through the failure of any party seeking to
                  terminate this Agreement to comply fully with its obligations
                  under this Agreement) on or before January 31, 1999, or such
                  later date as the parties may agree upon.

Borrowers' account(s) at the Lender (a "Check Request").

                  (b) Without in any way limiting the Borrowers' obligation to
confirm in writing any Notice of Borrowing, the Lender may act without liability
upon the basis of telephonic notice believed by the Lender in good faith to be

such case, the Borrowers hereby waive the right to dispute the Lender's record
of the terms of such telephonic Notice of Borrowing, except for the Lender's
manifest error.

                  (c) The Lender will make available each requested Revolving
Loan to the Borrower by crediting the proceeds thereof to the Borrowers'

unconditionally promise to pay to the Lender, and there shall become absolutely

unpaid interest accrued to such date on the amount of the principal of the
Revolving Loans being repaid or prepaid on such date. Whenever any interest on

set forth in this Agreement, the Lender agrees to lend to the Borrowers on the
Closing Date the principal amount of $5,500,000 (the "Term Loan"). The Lender

         Section 3.02. The Term Note. The Term Loan shall be evidenced by an
amended and restated promissory note of the Borrowers, in substantially the form
of Exhibit B hereto (the "Term Note"), dated the Closing Date and with

Loan and shall represent the obligation of the Borrowers to pay to the Lender at
such times as are provided herein the original principal amount of the Term Loan
to the Borrowers, plus interest accrued thereon, as set forth below. The Lender
will mark on the Term Note, or enter in a record pertaining thereto, the
original principal amount of the Term Loan made thereunder and repayments
thereof, provided that the failure by the Lender to make any such notation, or
any error made in so doing, shall not limit or otherwise affect the
unconditional obligation of the Borrowers hereunder or under the Term Note to
make payments of principal and interest on the Term Note as and when due. The
Term Note shall mature and be due and payable (subject to earlier acceleration
as herein provided) on February 1, 2002 (the "Term Loan Maturity Date").

                                       13

may not be reborrowed.

                  (b) The Borrowers shall have the right, at any time and from
time to time, to prepay the Term Loan made to the Borrowers hereunder, in whole
or in part, without premium or penalty, upon three (3) Business Days' prior
written or telephonic notice to the Lender, subject to Section 2.08 hereof. Any
partial prepayment of the Term Loan shall be in an amount equal to $10,000 or an
integral multiple thereof and shall be applied to the remaining principal
installments of the Term Loan in the inverse order of maturity. No optional
prepayment of a portion of the Term Loan shall relieve the Borrower from its

notice of default to the Borrower, the outstanding amounts of Revolving Loans
and the Term Loan shall bear interest, payable on demand, to the extent
permitted by law, compounded monthly at an interest rate equal to four percent
(4%) above the Prime Rate. Notwithstanding the foregoing provisions of this
Section 4.01, it is the intention of the Borrowers and the Lender that under no

any payment of proceeds of any condemnation or eminent domain proceedings in
respect of any such property, the Borrowers shall pay all such proceeds to the
Lender to be applied in the Lender's sole discretion to the Obligations in such
order as the Lender shall choose in its sole discretion. Notwithstanding the
foregoing, in the event that the insurance or condemnation proceeds resulting
from any individual loss of the Borrowers are no greater than $50,000 and so
long as no Event of Default shall have occurred hereunder or under any of the
other Loan Documents, Lender agrees to apply such proceeds to reimburse the
Borrowers for the



                                       14
<PAGE>

reasonable costs incurred in the restoration, repair or replacement of such
property, all on such terms as the Lender shall reasonably require.

the Lender, not later than 2:00 p.m., Boston time, on the due date of such
payment, and in immediately available and freely transferable funds.

                  (b) If any sum would, but for the provisions of this
subsection 4.03(b), become due and payable to the Lender by the Borrowers under
this Agreement or the Notes on any day which is not a Business Day, then such
sum shall become due and payable on the Business Day next succeeding the day on
which such sum would otherwise have become due and payable hereunder or

shall be adjusted by the Lender accordingly.

                  (c) All computations of interest and fees payable under this
Agreement or the Notes shall be made by the Lender on the basis of actual days

error, be final, conclusive and binding for all purposes.

                  (d) The Lender will determine the Prime Rate in effect from
time to time. Any change in the Prime Rate shall, for all purposes of this
Agreement and the Notes, become effective on, and from the beginning of the day
on which such change shall first be announced by the Lender in accordance with
the Lender's customary banking practices.

                  (e) Each payment which shall become due and payable by the
Borrowers under this Agreement or the Notes shall be made without set-off and
free and clear of and without deduction or withholding of any kind.

         Section 4.04. Use of Proceeds. The Borrowers agrees that the proceeds
of the Term Loan and the Initial Revolving Loans made on the Closing Date shall
be used by the Borrowers first to refinance the existing term loan in the
original principal amount of $2,800,000, then to finance the acquisition of OLI,
and then for general corporate purposes and working capital of the Borrowers.

                                   ARTICLE VII

         In order to induce the Lender to enter into this Agreement and to make
the Loans as herein provided for, the Borrowers jointly and severally make the
following representations and warranties, all of which shall survive the
execution and delivery of this Agreement and the making of the Loans and shall,
except to the extent such representations and warranties relate solely to facts
in existence or actions to be taken on the Closing Date, be deemed to be
incorporated in each Borrowing Base Certificate and be deemed repeated and
confirmed with respect to each borrowing hereunder as of the time of such
borrowing.

         Section 7.01. Corporate and Partnership Status. Each of AMBI and its
Subsidiaries is a duly organized and validly existing corporation in good
standing under the laws of its respective jurisdiction of incorporation, with
perpetual corporate existence, and has the corporate power and authority to own

presently proposes to engage. N21 is a duly organized and validly existing
limited partnership under the laws of its jurisdiction of incorporation, with
perpetual partnership existence and has the partnership power and authority to
own its respective properties and to transact the business in which it is
engaged or presently proposes to engage. Each of the Borrowers and their
Subsidiaries is duly qualified as a foreign corporation or partnership and in
good standing in all jurisdictions where the failure to so qualify would have a
material adverse effect on the operations, properties, business or financial
condition of the Borrowers or their Subsidiaries.

         Section 7.02. Corporate and Partnership Power and Authority. Each of
the Borrowers has the corporate or partnership power and authority to borrow and
to execute, deliver and carry out the terms and provisions of this Agreement,
the other Loan Documents executed and delivered by such parties and the

corporate or partnership action (including, without limitation, the obtaining of
any consent of any stockholder or partner of such Borrowers and their
Subsidiaries required by law or their respective charters or by-laws or
partnership agreement), to authorize the execution, delivery and performance of
this Agreement, the borrowings hereunder, and the execution, delivery and
performance of the other Loan Documents executed and/or delivered by it. This
Agreement and each of the other Loan Documents executed and delivered by the
Borrowers and their Subsidiaries constitutes the legal, valid and binding
obligations of the Borrowers and their Subsidiaries and are enforceable in
accordance with their respective terms.

         Section 7.03. No Violation of Agreements. Neither the Borrowers nor
their Subsidiaries are in material default under any indenture, mortgage, deed
of trust, agreement or other instrument to which any of them is a party or by
which they or any of their properties may be bound. Neither the execution and
delivery of this Agreement, or any of the other Loan Documents by the Borrowers
or any Subsidiary nor the consummation of the transactions herein and therein
contemplated, nor compliance with the provisions hereof or thereof will violate
any provision of the charter or by-laws of the Borrowers or any Subsidiary, or
any law, statute or regulation, or any order or decree of any court or
governmental instrumentality, or will conflict with, or result in the breach of,
or constitute a material default under, any indenture, mortgage, deed of trust,
agreement or other instrument to which the Borrowers or their Subsidiaries are a
party or by which they or any of their properties is bound, or, except as
contemplated under this Agreement, result in the creation or imposition of any
Lien upon any property of the Borrowers or their Subsidiaries.

         Section 7.04. No Burdensome Agreements. Neither the Borrowers nor their

governmental or administrative body or agency which challenges the validity or
propriety of the transactions contemplated under this Agreement or the other
Loan Documents or which is pending or threatened as of the date of this
Agreement and which is reasonably likely to result in any material adverse
change in the operations, properties, business, assets, liabilities or
condition, financial or otherwise, of the Borrowers, OLI or any Subsidiary. As
of the date of this Agreement, neither the Borrowers, OLI nor any Subsidiary is
a defendant in any action for money damages brought in any court, and no
unsatisfied judgment in connection with any such action has been docketed
against the Borrowers, OLI or any Subsidiary. The Borrowers nor OLI are in
default under any applicable statute, rule, order, decree or regulation of any
court, arbitrator or governmental body or agency having jurisdiction over the
Borrowers, OLI or any Subsidiary which default is reasonably likely to result in
a material adverse effect on the Borrowers, OLI or any Subsidiary or any of
their assets or properties.

audited consolidated and consolidating balance sheet of AMBI and its

sheet of OLI as at November 30, 1998 and December 31, 1997, and the related
statements of income, stockholders' equity and changes in cash flows for the

its Subsidiaries as of the dates thereof. The Borrowers, OLI and their
Subsidiaries had no direct or contingent liabilities as of such dates which are
required to be reflected or reserved for in such financial statements or the
footnotes thereto which are not so reflected or reserved for therein. There has

                                       23
<PAGE>

change in the assets, liabilities, properties, business and condition, financial
or otherwise, of the Borrowers, OLI and their Subsidiaries since June 30, 1998.
The Borrowers represent that as of the date hereof, the remaining outstanding
principal balance under that certain Promissory Note dated March 18, 1996 issued

governmental or public body or authority (other than normal reporting
requirements or filings under the provisions of Article VI) is required to
authorize, or is otherwise required in connection with, the execution, delivery
and performance of this Agreement and the other Loan Documents.

         Section 7.11. Disclosure. Neither the Schedules nor Exhibits hereto,
nor any certificate, statement, report or other document furnished to the Lender
by or on behalf of the Borrowers and their Subsidiaries in connection herewith
or in connection with any transaction contemplated hereby, nor this Agreement,
nor any other Loan Document, contains, at the time furnished, any untrue
statement of a material fact or omits to state any material fact necessary in
order to make the statements contained therein not misleading.

         Section 7.12. Regulations G, U and X. Neither the Borrowers, OLI nor
any Subsidiary own any "margin stock" as such term is defined in Regulations G
and U, as amended, of the Board. The proceeds of the borrowings made pursuant to
Articles II, III, IV and V hereof will be used by the Borrowers only for the
purposes set forth in Section 4.04 hereof. None of such proceeds will be used,
directly or indirectly, for the purpose of purchasing or carrying any margin
stock or for the purpose of reducing or retiring any Indebtedness which was
originally incurred to purchase or carry margin stock or for any other purpose
which might constitute any of the Loans under this Agreement a "purpose credit"
within the meaning of said Regulations G and U or Regulation X of the Board.
Neither the Borrowers nor any Subsidiary have taken and none of them will take
any action which would be reasonably likely to cause this Agreement or any of
the other Loan Documents to violate any regulation of the Board or any state
securities laws, in each case as in effect on the date hereof, and neither the
Borrowers nor any Subsidiary have a class of securities registered under the
Securities Exchange Act of 1934.

         Section 7.13. Employee Benefit Plans. (a) No "reportable event" (as
defined in Section 4043(b) of ERISA) (whether or not waived) has occurred or is
continuing with respect to any "employee pension benefit plan" (as defined in
Section 3(2) of ERISA) maintained for employees of the Borrowers, OLI or their
Subsidiaries (a "Pension Benefit Plan").

                  (b) No prohibited transaction (within the meaning of Section
406 of ERISA) has occurred with respect to any Pension Benefit Plan or any other
"employee benefit plan" (as defined in Section 3(3) of ERISA) (together with a
Pension Benefit Plan, an "Employee Plan") maintained for employees of the
Borrowers or their Subsidiaries and covered by Part 4 of the Subtitle B of Title
I of ERISA.

                  (c) With respect to each Pension Benefit Plan, the amount for
which the Borrowers, OLI or their Subsidiaries would be liable pursuant to the
provisions of Sections 4062, 4063 or 4064 of ERISA would be zero if such Plans
had terminated as of the Closing Date.

                  (d) Neither the Borrowers, OLI nor their Subsidiaries are now,
nor have been during the preceding five years, a contributing employer to a
"multiemployer plan" (as defined in Section 4001(a)(3) of ERISA) (a
"Multiemployer Plan"). Neither the Borrowers, OLI nor their Subsidiaries have
(i) ceased operations at a facility so as to become subject to the provisions of
Section 4062(f) of ERISA, (ii) withdrawn as a substantial employer so as to
become subject to the provisions of Section 4063 of ERISA, (iii) ceased making
contributions on or before the Closing Date to any Pension Benefit Plan subject
to the provisions of Section 4064(a) of ERISA to which the Borrowers, OLI and
their Subsidiaries made contributions during any of the five years prior to the
Closing Date, (iv) incurred or caused to occur a "complete withdrawal" (within
the meaning of Section 4203 of ERISA) or a "partial withdrawal" (within the
meaning of Section 4205 of ERISA) from a Multiemployer Plan that is a Pension
Benefit Plan so as to incur withdrawal liability under Section 4201 of ERISA
(without regard to subsequent reduction or waiver of such liability under
Sections 4207 or 4208 of ERISA), or (v) been a party to any transaction or
agreement under which the provisions of Section 4204 of ERISA were applicable.

                  (e) No notice of intent to terminate a Pension Benefit Plan
has been filed, nor has any Plan been terminated, pursuant to the provisions of
Section 4041(f) of ERISA.

                  (f) The PBGC has not instituted proceedings to terminate (or
appoint a trustee to administer) a Pension Benefit Plan and no event has
occurred or condition exists which might constitute grounds under the provisions
of Section 4042 of ERISA for the termination of (or the appointment of a trustee
to administer) any such Plan.

                  (g) With respect to each Pension Benefit Plan that is subject
to the provisions of Title I, Subtitle B, Part 3 of ERISA, the funding method
used in connection with such Plan is acceptable under ERISA, and the actuarial
assumptions used in connection with funding such Pension Benefit Plan are, in
the aggregate, reasonable. The assets of each such Pension Benefit Plan (other
than the Multiemployer Plans) are at least equal to the present value of the
greater of (i) accrued benefits (both vested and non-vested) under such Plan, or
(ii) "benefit commitments" (within the meaning of Section 4001(a)(16) of ERISA)
under such Plan, in each case as of the latest actuarial valuation date for such
Plan (determined in accordance with the same actuarial


                                       25
<PAGE>

assumptions and methods as those used by the Borrowers', OLI's and their
Subsidiaries actuaries in their valuation of such Plan as of such valuation
date). No such Pension Benefit Plan has incurred any "accumulated funding
deficiency" (as defined in Section 412 of the Code), whether or not waived.

                  (h) There are no actions, suits or claims pending (other than
routine claims for benefits) or, to the knowledge of the Borrowers, OLI or their
Subsidiaries, which could reasonably be expected to be asserted, against any
Employee Plan or the assets of any such plan. No civil or criminal action
brought pursuant to the provisions of Title I, Subtitle B, Part 5 of ERISA is
pending or, to the best of the Borrowers' knowledge, threatened against any
fiduciary of any Employee Plan. None of the Employee Plans or any fiduciary
thereof has been the direct or indirect subject of an audit, investigation or
examination by any governmental or quasi-governmental agency other than routine
audits or examinations.

                  (i) All of the Employee Plans comply currently, and have
complied in the past, both as to form and operation, with their terms and with
the provisions of ERISA and the Code, and all other applicable laws, rules and
regulations (including, but not limited to, each of the (1) Tax Equity and
Fiscal Responsibility Act of 1982, (2) Deficit Reduction Act of 1984, (3)
Retirement Equity Act of 1984, and (4) Consolidated Omnibus Budget
Reconciliation Act of 1985); all necessary governmental approvals for the
Employee Plans have been obtained and a favorable determination as to the
qualification under Section 401(a) of the Code of each of the Pension Benefit
Plans and each amendment thereto has been made by the Internal Revenue Service
and a recognition of exemption from federal income taxation under Section 501(a)
of the Code of each of the funded welfare benefit plans (within the meaning of
Section 3(1) of ERISA) has been made by the Internal Revenue Service, and
nothing has occurred since the date of each such determination or recognition
letter that would adversely affect such qualification.

                  (j) For purposes of all Sections of this Agreement dealing
with ERISA, the term "Borrowers, OLI and their Subsidiaries" shall include each
trade or business (whether or not incorporated) which together with the
Borrowers, OLI and their Subsidiaries would be treated as a single employer
under the provisions of Title I or IV of ERISA.

         Section 7.14. Subsidiaries. Except as set forth on Schedule 7.14, AMBI
has no Subsidiaries. N21 has no subsidiaries.

         Section 7.15. Permits, etc. Each of the Borrowers and their
Subsidiaries possesses all licenses, approvals and consents of Federal, state
and local governments and regulatory authorities as required to conduct properly
its business.

         Section 7.16. Solvency. Each of the Borrowers and its Subsidiaries,
both before and after giving effect to the transactions contemplated hereby, are
solvent, and has assets with a fair salable value in excess of the amount
required to pay its probable liabilities on existing debts as they become
absolute and matured. Each of the Borrowers and its Subsidiaries has, and will
have, access to adequate capital for the conduct of its business and the ability
to pay its debts from time to time incurred in connection therewith as such
debts mature.

         Section 7.17. Environmental Matters. (a) Except as set forth on
Schedule 7.17, neither the Borrowers, OLI nor their Subsidiaries has ever owned,
occupied or operated a site or vessel on which any hazardous material or oil was
or is stored without compliance with all statutes, regulations, ordinances,
directives and orders of every federal, state, municipal and other governmental
authority with jurisdiction relative thereto, or disposed of, transported, or
arranged for the transport of any hazardous material or oil without compliance
with all such statutes, regulations, ordinances, directives and orders, or
caused or been legally responsible for any release of any hazardous material or
oil; (b) the Borrowers, OLI and their Subsidiaries shall not dispose of any
hazardous material or oil on any site or vessel owned, occupied or operated by
the Borrowers, OLI and their Subsidiaries, nor store on any site or vessel
owned, occupied or operated by the Borrowers, OLI and their Subsidiaries, nor
transport or arrange for the transport of, any hazardous material or oil except
if such storage or transport is in the ordinary course of the Borrowers', OLI's
and Subsidiaries' business, and is in compliance with all such statutes,
regulations, ordinances, directives and orders and shall take all such action
(including, without limitation, engineering tests) as Lender may from time to
time reasonably require to confirm that there has been no release of any
hazardous material or oil on any site or vessel owned, occupied or operated by
the Borrower, OLI and their Subsidiaries; (c) the Borrowers shall indemnify, and
shall cause their Subsidiaries to indemnify, and hold the Lender harmless from
all loss, cost or expense (including reasonable attorneys' fees and expenses)
suffered by the Lender as a result of any claim brought against the Lender by
any governmental agency or authority or any other person on account of the
release of hazardous materials or oil on or from any site or vessel owned,
occupied or operated by the Borrowers, OLI or their Subsidiaries, or the failure

reasonable judgment with counsel of the Lender's selection, but at the expense
of the Borrowers, OLI or their Subsidiaries). Such indemnification shall survive
payment of the Obligations. As used herein the terms "site," "vessel" and

of the General Laws of Massachusetts.

Common Stock, no par value per share, of which as of the date hereof, 100 shares
have been issued on a fully diluted basis. All of the foregoing shares have been
duly and properly issued and are outstanding and are fully paid-up and
non-assessable. N21 is wholly owned by AMBI. All of the partnership interests of
N21 and the stock of Selene and JBE are owned and held free and clear of all
mortgages, liens, pledges, charges, security interests and other encumbrances of
every kind whatever.

                  (b) Except as disclosed on Schedule 7.18, there are no
outstanding commitments, options, warrants, calls or other agreements or
obligations (whether written or oral) binding on the Borrowers, Selene and/or
JBE which require or could require the Borrowers, Selene and/or JBE to issue,
sell, grant, transfer, assign, mortgage, pledge or otherwise dispose of (i) any
shares of any class in the capital of the Borrowers, (ii) any securities
exchangeable for or convertible into or carrying any rights to acquire any

restrictions on transfer pursuant to any charter or incorporation documents or
by-laws, or (ii) any shareholder agreements, voting agreements, voting trusts,
trust agreements, trust deeds, irrevocable proxies or any other similar
agreements or instruments (whether written or oral).

                  Section 7.19 Year 2000 Compliance. The Borrowers have made a
comprehensive review and assessment of their computers and similar devices,
including embedded microchips in non-computing devices (collectively, "Computing
Devices"), and have made inquiry of their material suppliers, vendors and
customers with respect to their Computing Devices concerning the possibility
that such Computing Devices may not properly perform date-sensitive functions on
and after December 31, 1999 or with respect to dates occurring on and after
December 31, 1999 (the "Year 2000 Problem"). Based on such review and
assessment, and upon such inquiries, the Borrowers believe that either (i) the
Year 2000 Problem will not affect such Computing Devices, or (ii) the Year 2000
Problem, including any costs of remediation, could not reasonably be expected to
result in an Event of Default or a material adverse change in the Borrrower's
business, operations, financial condition or prospects. The Borrowers have
developed feasible contingency plans adequate to ensure uninterrupted and
unimpaired business operation in the event of failure of its own or a third
party's Computing Devices due to the Year 2000 Problem, as well as in the event
of a general failure of or interruption in their communications and delivery
infrastructure.

         All nonpublic information obtained by the Lender pursuant to this

external auditors and legal advisors. Notwithstanding the above, the Lender is
hereby authorized to deliver a copy of any financial statement or any other
information relating to the business, operations or financial condition of the
Borrowers and their Subsidiaries which may be furnished to it hereunder or
otherwise, to any court, regulatory body or agency having jurisdiction over the
Lender or to any Person which shall, or shall have any right or obligation to,

Agreement, the other Loan Documents or any Collateral.

and duly observe, all valid requirements of governmental authorities (including,
without limitation, ERISA and the rules and regulations promulgated thereunder),
and all applicable statutes, rules, regulations and orders relating to
environmental protection and to public and employee health and safety
(including, without limitation, OSHA and the rules and regulations promulgated
thereunder).

         Section 8.04. Payment of Taxes and Claims, etc. Pay, and cause their
Subsidiaries to pay, (i) all taxes, assessments and governmental charges imposed
upon it or upon their property and (ii) all material claims (including, without
limitation, claims for labor, materials, supplies or services) which might, if
unpaid, become a Lien upon their property prior to becoming delinquent;
provided, however, that any such tax, assessment, charge or claim need not be
paid if the validity or amount thereof is being contested in good faith by
appropriate proceedings and if the Borrowers and their Subsidiaries have
established adequate reserves with respect thereto; and provided, further that
the Borrowers and their Subsidiaries shall pay all such taxes, assessments,
charges and claims forthwith upon the attachment of any Lien to the Collateral
or any portion thereof, which Lien shall not have been released within five days
of its attachment.

         Section 8.05. Keeping of Books, Visitation, Inspection, etc.

                  (a) Keep, and cause their Subsidiaries to keep, proper books
of record and account, containing complete and accurate entries of all financial

prepare the financial statements described in Section 8.01 hereof.

                  (b) Permit any representative of the Lender to visit and
inspect any of the Borrowers' property and that of their Subsidiaries, to
examine their books and records and to make copies and take extracts therefrom,
and to discuss their affairs, finances and accounts with its officers, all at

upon reasonable prior notice to the Borrowers and their Subsidiaries provided no
Event of Default has occurred.

         Section 8.06. Insurance. (a) (i) Keep, and cause their Subsidiaries to
keep, all of their properties adequately insured, at all times, with insurance
carriers satisfactory to the Lender, in


                                       31
<PAGE>

amounts and pursuant to insurance policies reasonably acceptable to the Lender,
against loss or damage by fire and other hazards, (ii) maintain, and cause their
Subsidiaries to maintain, adequate insurance, at all times with insurance
carriers reasonably satisfactory to the Lender, in amounts and pursuant to
insurance policies reasonably acceptable to the Lender against liability on
account of damage to persons and property and under all applicable workers'
compensation laws, and (iii) maintain, and cause their Subsidiaries to maintain,
adequate insurance, covering such other risks as the Lender may reasonably
request. All insurance premiums shall be paid as they become due or as may be
permitted either through existing plans or through such payment plans as are
hereafter reviewed and approved by the Lender in its sole discretion. All
insurance covering tangible property subject to a Lien in favor of the Lender
granted pursuant to this Agreement or under any other Loan Document shall
provide that, in the case of each separate loss, the full amount of insurance
proceeds with respect thereto shall be payable to the Lender as secured party or
otherwise as its interests may appear, to be applied in accordance with Section
4.02 hereof, and shall further (w) provide for at least 30 days' prior written
notice to the Lender of the cancellation or substantial modification thereof,

the Borrowers or any other Person, (y) insure the Lender's interests regardless
of any breach of or violation by the Borrowers or any other Person of any
warranties, declarations, or conditions contained in such insurance, and (z)
provide that the Lender shall have the right (but not the obligation) to cure
any default by the Borrowers or any Person under such insurance. Each liability
policy required pursuant to this Section 8.06 shall name the Lender as an
additional insured and loss payee and shall be primary without right of
contribution from any other insurance which is carried by the Lender to the
extent that such other insurance provides the Lender with contingent and/or
excess liability insurance with respect to its interest as such in the
Collateral and shall expressly provide that all of the provisions thereof,
except the limits of liability (which shall be applicable to all insureds as a
group) and except liability for premiums (which shall be solely a liability of
the Borrowers or such Subsidiary), shall operate in the same manner as if there
were a separate policy covering each insured.

                  (b) From time to time upon request of the Lender, promptly
furnish or cause to be furnished to the Lender evidence, in form and substance
satisfactory to the Lender, of the maintenance of all insurance required to be
maintained by Section 8.06(a) hereof, including, but not limited to, such
originals or copies as the Lender may request of policies, certificates of
insurance, riders and endorsements relating to such insurance and proof of
premium payments.

                  (c) Immediately upon receipt thereof, provide to the Lender a
copy of any notice of cancellation or suspension of any insurance coverage.

         Section 8.07. Properties in Good Condition. Keep, and cause their
Subsidiaries to keep, their leased properties in good repair, working order and
condition and, from time to time, make all needed and proper repairs, renewals,
replacements, additions and improvements thereto, in accordance with the terms
of the applicable leases so that the business carried on by the Borrowers and
their Subsidiaries may be properly and advantageously conducted at all times in
accordance with prudent business management.

         Section 8.08. Maintenance of Liens. Except for the filing of
continuation statements and



                                       32
<PAGE>

the making of other filings by the Lender as secured party or assignee, at all
times take all action necessary, and cause their Subsidiaries to take all action
necessary, to maintain the Liens and security interests provided for under or
pursuant to this Agreement or the other Loan Documents as valid and perfected
first Liens on the property intended to be covered thereby (subject only to
Liens expressly permitted hereunder) and supply all information to the Lender
necessary for such maintenance.

         Section 8.09. Notice of Default. Notify, and cause their Subsidiaries
to notify the Lender in writing promptly upon becoming aware of any default or
event, condition or occurrence which with notice or lapse of time, or both,
would constitute a default under any agreement for borrowed money to which the
Borrowers or any Subsidiary are parties or by which any of their assets are
bound or under any lease agreement to which the Borrowers or any Subsidiary are
parties.

         Section 8.10. Further Assurances. At the expense of the Borrowers, upon
request of the Lender, duly execute and deliver, or cause to be duly executed
and delivered to the Lender such further instruments and take and cause to be
taken such further actions as may be necessary or proper in the reasonable
opinion of the Lender to carry out more effectually the provisions and purposes
of this Agreement and the other Loan Documents.

         Section 8.11. ERISA.

                  (a) Pay and discharge, and cause their Subsidiaries to pay and
discharge promptly any liability imposed upon it pursuant to the provisions of
the Code and Title IV of ERISA; provided, however, that neither the Borrowers
nor any Subsidiary shall be required to pay any such liability if (1) the
amount, applicability or validity thereof shall be diligently contested in good
faith by appropriate proceedings and (2) the Borrowers or their Subsidiaries
shall have set aside on their books reserves which, in the opinion of the
Borrowers' independent certified public accountants, are adequate with respect
thereto.

                  (b) Deliver, and cause their Subsidiary to deliver to the
Lender promptly and in any event within 10 days, after (i) the occurrence of any
"reportable event" (within the meaning of Section 4043(b) of ERISA) with respect
to any Pension Benefit Plan, a copy of the materials that are filed with the
PBGC, or the materials that would have been required to be filed if the 30-day
notice requirement to the PBGC was not waived, (ii) the Borrowers or their
Subsidiaries or an administrator of any Pension Benefit Plan files with
participants, beneficiaries or the PBGC a notice of intent to terminate any such
Plan, a copy of any such notice, (iii) the receipt of notice by the Borrowers or
their Subsidiaries or an administrator of any Pension Benefit Plan from the PBGC
of the PBGC's intention to terminate any Pension Benefit Plan or to appoint a
trustee to administer any such Plan, a copy of such notice, (iv) the filing
thereof with the Internal Revenue Service, copies of each annual report that is
filed on Treasury Form 5500 with respect to any Pension Benefit Plan or Employee
Plan, together with certified financial statements (if any) for the Plan and any
actuarial statements on Schedule B to such Form 5500, (v) the Borrowers or their
Subsidiaries know or have reason to know of any event or condition which might
constitute grounds under the provisions of Section 4042 of ERISA for the
termination of (or the appointment of a trustee to administer) any Pension
Benefit Plan, an

                                       33
<PAGE>

explanation of such event or condition, (vi) the receipt by the Borrowers of an
assessment of withdrawal liability under Section 4201 of ERISA from a
Multiemployer Plan, a copy of such assessment, or (vii) the Borrowers or their
Subsidiaries know or have reason to know that an application is to be, or has
been made to the Secretary of the Treasury for a waiver of the minimum funding
standard under the provisions of Section 412 of the Code, a copy of such
application, in each case together with a statement signed by the treasurer or
controller of the Borrowers or such Subsidiary setting forth details as to such
reportable event, notice, event or condition and the action which the Borrowers
or their Subsidiaries propose to take with respect thereto.

         Section 8.12. Appraisals. Upon the reasonable request of the Lender no
more than once annually provided that no Event of Default shall have occurred,
deliver appraisals on all property owned and operated by the Borrowers and their
Subsidiaries, which appraisals shall be prepared by appraisers reasonably
satisfactory to the Lender at the expense of the Borrowers and shall be in form
reasonably satisfactory to the Lender.

Flow, for purposes of the foregoing, shall be calculated on an annual basis
based on the audited financial statements for Fiscal Year 1999, Fiscal Year 2000
and Fiscal Year 2001, respectively and shall be due within no more than one
hundred and twenty (120) days after completion of such audited financial
statements.

         Section 8.15 Assignment of Life Insurance. In the event that the
Borrowers obtain life insurance policies on the life of Marvin Segel at any time
after the Closing Date, the Borrowers shall within thirty (30) days of the
issuance of any such policies assign such policies in favor of the Lender, such

provision contained herein or in any document or instrument delivered in
connection with or pursuant to this Agreement, or to enforce the payment of the
Obligations or any other legal or equitable right or remedy.

         Section 10.03. Rights and Remedies Cumulative. No right or remedy
herein conferred upon the Lender is intended to be exclusive of any other right
or remedy contained herein or in any instrument or document delivered in
connection with or pursuant to this Agreement, and every such right or remedy
shall be cumulative and shall be in addition to every other such right or remedy
contained herein and therein or now or hereafter existing at law or in equity or
by statute, or otherwise.

         Section 10.04. Right of Setoff. In addition to and not in limitation of
all rights of offset that the Lender may have under applicable law, the Lender
shall, upon the occurrence and during the continuance of any Event of Default
and whether or not the Lender has made any demand or any Obligations are
matured, have the right to appropriate and apply to the payment of the
Obligations, all deposits (general or special, time or demand, provisional or
final) then or thereafter held by and other indebtedness or property then or
thereafter owing to the Borrowers by the Lender, whether or not related to this
Agreement, the other Loan Documents or any transaction hereunder regardless of
the existence or sufficiency of any other Collateral therefor.

         Section 11.03. No Waiver. No failure or delay on the part of the Lender
in exercising any right, power or remedy hereunder or under any other Loan
Document and no course of dealing between the Borrowers or any Subsidiary and
the Lender shall operate as a waiver of any thereof, nor shall any single or

right, power or remedy preclude any other or further exercise thereof or the
exercise of any other right, power or remedy hereunder. No notice to or demand

<PAGE>

any Subsidiary to any other or further notice or demand in similar or other

further action in any circumstances without notice or demand.

         Section 11.04. Payment of Expenses, Indemnity, etc. The Borrowers
shall:

                  (a) except as specifically limited herein, whether or not the
transactions hereby contemplated are consummated, pay all out-of-pocket costs
and expenses of the Lender in the administration (both before and after the
execution hereof and including advice of counsel as to the rights and duties of
the Lender with respect thereto) of, and in connection with the preparation,
execution and delivery of, preservation of rights under, enforcement of, and
refinancing, renegotiation or restructuring of, this Agreement, the Notes, the
other Loan Documents and the documents and instruments referred to herein and
therein and any amendment, waiver or consent relating thereto (including,
without limitation, the fees and disbursements of counsel for the Lender in each
instance and all reasonable travel, lodging and related costs of Lender in
connection with any periodic site visits to the Borrowers during the term of the
Loans in connection with its review of the Borrowers' business);

                  (b) pay and hold the Lender harmless from and against any and
all present and future stamp and other similar taxes with respect to the
foregoing matters and hold the Lender harmless from and against any and all
liabilities with respect to or resulting from any delay or omission to pay such
taxes;

                  (c) indemnify, defend and hold harmless the Lender and its
directors, officers, agents, employees and counsel from and against any and all
losses, claims, damages, liabilities, deficiencies, judgments or expenses
incurred by any of them (except to the extent that it is finally judicially
determined to have resulted from their own gross negligence or willful
misconduct) arising out of or by reason of any litigations, investigations,
claims or proceedings, pending or threatened, which arise out of or are in any
way related to (i) any actual or proposed use by the Borrowers of the proceeds
of the Loans or (ii) the Lender's entering into this Agreement, any of the other
Loan Documents including, without limitation, amounts paid in settlement, court
costs and the fees and disbursements of counsel incurred in connection with any
such litigation, investigation, claim or proceeding.

         If and to the extent that the obligations of the Borrowers under this
Section 11.04 are unenforceable for any reason, the Borrowers hereby agree to
make the maximum contribution to the payment and satisfaction of such
obligations which is permissible under applicable law. The Borrowers'
obligations under this Section 11.04 shall survive any termination of this
Agreement and the payment in full of the Obligations.

         Section 11.05. Benefit of Agreement. (a) This Agreement shall be
binding upon and inure to the benefit of and be enforceable by the respective
successors and assigns of the parties hereto, provided that the Borrowers may
not assign or transfer any of their interest hereunder without the prior written
consent of the Lender.

                  (b) The Lender may make, carry or transfer Loans at, to or for
the account of,


                                       45
<PAGE>

any of its branch offices or the office of an Affiliate of the Lender.

                  (c) (i) The Lender may assign its rights, but may not delegate
its obligations, under this Agreement and further may assign, or sell
participations in, all or any part of any Loan or Loans made by it or any other
interest herein or in its Notes to another bank or insurance company or pension
fund, in which event (A) in the case of an assignment, upon notice thereof by
the Lender to the Borrowers, the assignee shall have, to the extent of such
assignment (unless otherwise provided therein), the same rights and benefits as
it would have if it were the Lender hereunder and the holder of a Note, and (B)
in the case of a participation, the participant shall not have any rights under
this Agreement or any Note or any other Loan Document, except as set forth in
this Section 11.05(c) (the participant's rights against the Lender in respect of
such participation to be those set forth in the agreement executed by the Lender
in favor of the participant relating thereto). The Lender may furnish any
information concerning the Borrowers in the possession of the Lender from time
to time to assignees and participants (including prospective assignees and
participants). In the event that the Lender assigns or sells a participation in
all or any part of the Notes or the Loans or any interest in the Collateral in
connection therewith to any Person other than an Affiliate of the Lender, the
Lender shall endeavor to give the Borrowers prompt notice thereof, provided that
the failure of the Lender to give such notice shall not result in any liability
to the Lender.

                      (ii) The Borrowers hereby grant to each participant in the
Loans, and each such participant shall have and is hereby given, a continuing
lien on and security interest in any and all monies, securities, and other
property of the Borrowers and the proceeds thereof, now or hereafter held or
received by such participant, and also upon any and all deposits (general or
special) and credits of the Borrowers with, and any and all claims of the
Borrowers against, such participant, at any time existing, including the right
of setoff, to the extent of such participant's participation in the Loans, and
such participant shall be deemed to have, the same right of setoff to the extent
of such participant's participation in the Loans as it would if it were a direct
lender.

         Section 11.06. Governing Law, Submission to Jurisdiction, etc.

                  (a) This Agreement and the rights and obligations of the
parties hereunder and under the Notes shall be construed in accordance with and
be governed by the laws of the Commonwealth of Massachusetts (without giving
effect to the conflict of law principles thereof).

                  (b) Any legal action or proceeding with respect to this
Agreement or the Notes or any other Loan Document may be brought in the courts
of The Commonwealth of Massachusetts or of the United States of America for the
District of Massachusetts, and, by execution and delivery of this Agreement, the
Borrowers hereby accept for itself and their Subsidiaries and in respect of
their respective property, generally and unconditionally, the jurisdiction of
the aforesaid courts.

                  (c) The Borrowers hereby irrevocably waive, in connection with
any such action or proceeding, (i) any objection, including, without limitation,
any objection to the laying of venue or based on the grounds of forum non
conveniens, which it may now or hereafter have to the bringing of any such
action or proceeding in such respective jurisdictions, (ii) the right to


                                       46
<PAGE>

interpose any setoff, non-compulsory counterclaim or cross-claim and (iii) to
the maximum extent not prohibited by law, the Borrowers, and the Lender each
hereby knowingly, voluntarily and intentionally waive any right they may have to
a trial by jury in respect of any litigation directly or indirectly arising out
of, under or in connection with this Agreement, the other Loan Documents, or the
transactions contemplated hereby or thereby.

                  (d) The Borrowers irrevocably consent to the service of
process of any of the aforementioned courts in any such action or proceeding by
the mailing of copies thereof by registered or certified mail, postage prepaid,
to the Borrowers at their address set forth in Section 11.01 hereof.

                  (e) Nothing herein shall affect the right of the Lender to
serve process in any other manner permitted by law or to commence legal
proceedings or otherwise proceed against the Borrowers in any other
jurisdiction.

         Section 11.07. Counterparts. This Agreement may be executed in any
number of counterparts and by the different parties hereto on separate
counterparts, each of which when so executed and delivered shall be an original,
but all of which shall together constitute one and the same agreement.

         Section 11.08. Collection Costs. In the event that the Lender shall
retain an attorney or attorneys to collect, enforce, protect, maintain, preserve
or foreclose its interests with respect to this Agreement, the Loans, the Notes,
any other Loan Document, any Obligations, any Receivable, or the lien or
security interest in any Collateral or any other security for the Obligations or
under any instrument or document delivered pursuant to this Agreement, or in
connection with any Obligations, or to protect the rights of any holder or
holders with respect thereto, the Borrowers shall pay all of the reasonable
costs and expenses actually incurred of such collection, enforcement or
protection, including, without limitation, reasonable attorneys' fees, which
amounts shall be part of the Obligations, and the Lender may take judgment for
all such amounts.

         Section 11.09. Termination of Agreement. (a) The Borrowers may
terminate this Agreement at any time upon (i) the delivery to the Lender of
irrevocable notice of its intention to terminate this Agreement and (ii) payment
of all Obligations of the Borrowers to the Lender under or in respect of this
Agreement, the Notes and the other Loan Documents, including, without
limitation, the principal amount of all Loans outstanding as of the date of such
payment, all interest accrued thereon through the date of such payment, and all
fees and expenses accrued and unpaid through the date of such payment.

                  (b) The Lender may terminate this Agreement immediately, at
any time during the continuance of an Event of Default under Article X;
provided, however, that this Agreement shall automatically terminate if there
shall occur an Event of Default under Section 10.01(e) or 10.01(f) hereof.

                  (c) The termination of this Agreement shall not affect any
rights of the Borrowers or the Lender arising prior to the effective date of
such termination, and the provisions 


                                       47


<PAGE>



hereof shall continue to be fully operative until all transactions entered into,
rights created or Obligations incurred prior to such termination have been fully
disposed of, concluded or liquidated. Upon the termination of this Agreement,
all Obligations (including, without limitation, the Loans) shall be due and
payable without notice or demand. The security interests, liens and rights
granted to the Lender hereunder and under the Loan Documents shall continue in
full force and effect, notwithstanding the termination of this Agreement or the
fact that the Borrowers' accounts may from time to time be temporarily in a
credit position, until all of the Obligations have been paid in full after the
termination hereof. All representations, warranties, covenants, waivers and
agreements contained herein shall survive termination hereof unless otherwise
provided. Notwithstanding the foregoing, if after receipt of any payment of all
or any part of the Obligations, the Lender is for any reason compelled to
surrender such payment to any Person or entity because such payment is
determined to be void or voidable as a preference, impermissible setoff, a
diversion of trust funds or for any other reason, this Agreement shall continue
in full force and the Borrowers shall be liable to, and shall indemnify and hold
the Lender harmless for, the amount of such payment surrendered until the Lender
shall have been finally and irrevocably paid in full. The provisions of the
foregoing sentence shall be and remain effective notwithstanding any contrary
action which may have been taken by the Lender in reliance upon such payment,
and any such contrary action so taken shall be without prejudice to the Lender's
rights under this Agreement and shall be deemed to have been conditioned upon
such payment having become final and irrevocable.

         Section 11.10. Headings Descriptive. The headings of the several
articles and sections of this Agreement, and the Table of Contents, are inserted
for convenience only and shall not in any way affect the meaning or construction
of any provision of this Agreement.

         Section 11.11. Entire Agreement. This Agreement, together with the
other Loan Documents and the Subordination Agreements, embodies the entire
agreement and understanding among the parties relating to the subject matter
hereof and supersedes all prior proposals, negotiations, agreements and
understandings relating to such subject matter. Each of the Borrowers certifies
that it is relying on no statement, representation, warranty, covenant or
agreement of any kind except for those set forth in this Agreement and the other
Loan Documents.

         Section 11.12. Waiver of Rights Related to Damages. To the maximum
extent not prohibited by law, the Borrowers and the Lender each hereby
knowingly, voluntarily and intentionally waives any right it may have to claim
or recover in any litigation directly or indirectly arising out of, under or in
connection with this Agreement, the other Loan Documents, or the transactions
contemplated hereby or thereby any special, exemplary, punitive or consequential
damages or any damages other than, or in addition to, actual damages, unless
such claim is with respect to the willful misconduct or gross negligence of the
Lender.

         Section 11.13. Certifications. The Borrowers and the Lender each hereby
certifies that neither any representative or agent of the Lender nor the
Lender's counsel has represented, expressly or otherwise, or implied that the
Lender would not, in the event of litigation, seek to enforce the waivers set
forth in subsection 11.06(c) and Section 11.12 hereof. The Borrowers and the
Lender each acknowledge that they have been induced to enter into this Agreement
by,


                                       48
<PAGE>

 among other things, the mutual waivers and certifications herein.

         Section 11.14. Severability. In the event that any court of competent
jurisdiction shall determine that any provision, or any portion thereof,
contained in this Agreement shall be unreasonable or unenforceable in any
respect, then such provision shall be deemed limited to the extent that such
court deems it reasonable and enforceable, and as so limited shall remain in
full force and effect. In the event that such court shall deem any such
provision, or portion thereof, wholly unenforceable, the remaining provisions of
this Agreement shall nevertheless remain in full force and effect.

Exhibit 20.1

                   AMBI ACQUIRES LITE BITES(R) NUTRITION BARS

     ACQUISITION OF PROFITABLE BRAND NAME PRODUCT SOLD ON THE QVC TELEVISION
          NETWORK ADDS TO AMBI'S DIRECT-TO-CONSUMER NUTRITION BUSINESS


         Purchase, New York, January 22, 1999 --- AMBI Inc. (NASDAQ: AMBI)
announced that it purchased the business and assets of Optimum Lifestyle, Inc.
(OL), a Sausalito, California company engaged in the development and marketing
of premium nutrition bars sold on the QVC television network under the trademark
Lite Bites(R). Terms of the transaction included the payment by AMBI of $6
million in cash and 1.3 million shares of AMBI common stock. In addition, AMBI
has agreed to make contingent payments based upon the achievement of certain
future sales levels of Lite Bites(R).

         AMBI noted that Lite Bites(R) had sales of approximately $5.5 million,
generated Earnings Before Interest, Taxes, Depreciation, and Amortization
(EBITDA) of about $1.3 million in the year ended December 31, 1998, and that the
acquisition would be accretive to earnings.

         Fredric D. Price, AMBI's President and Chief Executive Officer, said,
"The acquisition of Lite Bites(R) offers AMBI an ideal fit with our products and
distribution channels in the following three ways. First, it enables us to enter
one of the fastest growing segments of the nutritional supplement business with
a proven consumer-accepted, brand name product. Second, it adds a leading
Direct-to-Consumer distribution channel, the QVC television network, to our
catalog (Heart's Content(TM)) and internet e-commerce site
(www.CardiaNutrition.com) initiatives, which are expected to be up and running
later this year. Third, it forms the basis for developing and launching new and
improved proprietary bar products that will include one or more of our patented
nutrition ingredients.

         "AMBI has positioned itself strategically to be in all three segments
- --- Retail, Direct-to-Consumer, and Ingredients --- of the nutrition business.
Our mission is both to develop and acquire new, proprietary nutrition products
to market in each of these business segments."

         According to the Nutrition Business Journal, sales of nutrition bars
increased 40% in 1997 and reached a sales level in excess of $300 million in
1998.


<PAGE>




         Lite Bites(R) nutrition bars contain a custom herbal blend and
twenty-two important vitamins and minerals. They are sold as part of a total
lifestyle system for weight management, come in twelve flavors, and have a
reputation for great taste.

         Obesity and fat intake are major risk factors for cardiovascular
diseases and Type 2 diabetes, and the control of weight and fat intake is
recommended by the American Diabetes Association, the American Heart
Association, and the National Institutes of Health. The Lite Bites(R) products
have been designed for use as part of a fat fighting system for people concerned
about these risk factors. This approach is consistent with AMBI's other products
such as CARDIA(R) SALt and ChromAx(R) chromium picolinate.

         Commenting on the acquisition, Cheryl and Dean Radetsky, creators of
Lite Bites(R), said, in a joint statement, "We are pleased to have joined forces
with AMBI, as they share our commitment to creating high quality nutrition
products that address unmet consumer needs, especially in the area of weight
control and living a healthier lifestyle. As consultants to AMBI, we will work
with senior management in the development of new, patented Lite Bites(R)
products."

         The Company noted that this was the third major nutrition transaction
it had entered into in the last year and a half. The previous two were the
August 1997 acquisition of Nutrition 21, a leading nutrition supplements
ingredients developer and marketer, and the October 1998 strategic alliance with
the Whitehall-Robins Healthcare Division of American Home Products Corporation
(NYSE: AHP), concerning the retail distribution of CARDIA(R) SALT as well as
rights to distribute additional AMBI nutrition products in the retail channel in
the future.

         Financing for the acquisition came from both AMBI's own cash resources
as well as a loan from State Street Bank and Trust (SSBT.) The Company noted
that the loan from SSBT that was secured in August 1997 to finance the
acquisition of Nutrition 21 has been completely repaid.

         AMBI develops and markets proprietary nutrition products.

the year ended June 30, 1998. Actual results and timing of certain events could
