                            ASSET PURCHASE AGREEMENT

      THIS ASSET PURCHASE AGREEMENT (this "AGREEMENT") is made and entered into
as of January 17, 2003, by and among Bronson Nutritionals, LLC, a New York
limited liability company ("BUYER"), Kabco Pharmaceuticals, Inc., a New York

("SELLER"), and Twin Laboratories Inc., a Utah corporation and parent
corporation of Seller ("PARENT").

      A. Seller is engaged in the business of selling branded vitamins and
nutritional supplements through its direct to consumer mail-order catalogs and

conducted on the date hereof (the "BUSINESS").

      B. Parent owns all of the issued and outstanding shares of capital stock
of Seller.

      C. Seller desires to sell and assign to Buyer, and Buyer desires to
purchase from Seller certain assets and rights of Seller on the terms and
conditions set forth in this Agreement.

      NOW, THEREFORE, in consideration of the foregoing premises and the mutual
representations, warranties and agreements set forth herein, and for other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto, intending to be legally bound, agree as
follows:

1. SALE AND TRANSFER OF ASSETS.

      1.1   Assets.

            (a) Acquired Assets. On the terms and subject to the conditions set
forth in this Agreement, on the date hereof (the "CLOSING DATE"), Seller,
pursuant to a Bill of Sale in the form of Exhibit A (the "BILL OF SALE"), is
conveying, transferring, assigning, selling and delivering to Buyer, and Buyer
is acquiring, accepting and purchasing, all of Seller's right, title and
interest in the assets listed on Schedule 1.1(a) (the "ACQUIRED ASSETS").

            (b) Excluded Assets. Seller is not selling, and Buyer is not
purchasing, any of the assets of Seller listed on Schedule 1.1(b) (the "EXCLUDED
ASSETS"), all of which shall be retained by Seller.

      1.2 No Assumption of Liabilities. It is understood and agreed that, except
as set forth on Schedule 1.2, Buyer is not assuming, and will not be obligated
or liable for, any direct or indirect debts, obligations, claims or liabilities
of Seller or Parent of any nature related to the Business, the Acquired Assets
or otherwise, whether absolute, accrued, contingent, liquidated or otherwise,
and whether due or to become due, asserted or unasserted, known or unknown,
including Seller's obligations in respect of taxes, employee benefit or profit
sharing plans, or litigation to which the Seller is a party. Buyer shall not
have any liabilities or obligations by reason of this Agreement, except as
expressly provided in this Agreement. Buyer will be indemnified, pursuant to
Section 5.2, from and against any claims in respect of any debts,


                                       1
<PAGE>

obligations, claims or liabilities of Seller or Parent, except to the extent
expressly assumed hereunder.

      1.3 Closing. The closing of the sale and purchase of the Acquired Assets
(the "CLOSING") is taking place at 10:00 a.m., Eastern Standard Time, on the
date hereof, at the offices of Latham & Watkins, 885 Third Avenue, New York, New
York 10022. On the date hereof, Seller is conveying, transferring, assigning,
selling and delivering to Buyer the Acquired Assets, by delivery to Buyer of the
Bill of Sale, and Buyer is paying to Seller the Purchase Price as provided in
Section 1.4.

      1.4 Purchase Price. The consideration to be paid by Buyer for the Acquired
Assets (the "PURCHASE PRICE") is $5,000,000, which shall be paid by wire
transfer of immediately available funds to the account designated in writing by
Seller at least two business days prior to the Closing.

      1.5 Purchase Price Allocation. The Purchase Price will be allocated for
tax purposes (the "ALLOCATION") in the manner set forth on Schedule 1.5. The
Allocation will be used by the parties in preparing all applicable tax returns
and shall be binding upon the parties and upon each of their successors and
assigns, and the parties shall report the transaction herein for tax purposes in
accordance with the Allocation and shall not take any position or action
inconsistent with the Allocation.

2. REPRESENTATIONS AND WARRANTIES OF SELLER AND PARENT.

      Each representation and warranty contained in this Article 2 is qualified
by the disclosures made in the disclosure schedule attached hereto, which is
arranged in paragraphs corresponding to the numbered and lettered paragraphs in
this Article 2 (the "DISCLOSURE SCHEDULE"). This Article 2 and the Disclosure
Schedule shall be read together as an integrated provision. Seller and Parent,
jointly and severally, represent and warrant to Buyer, as of the date hereof,
that:

      2.1 Organization and Good Standing. Seller is a corporation validly
existing and in good standing under the laws of the State of Delaware, with full
corporate power and authority to carry on the Business as it is now being
conducted, and to own, lease or operate the Acquired Assets. Seller is duly
qualified to do business and is in good standing in the State of New York and
every jurisdiction in which the character of the properties owned or leased by
it or the nature of the business conducted by it makes such qualification
necessary, except where failure to be so qualified has not and could not
reasonably be expected to have a material adverse effect on the business,
operations, assets, results of operations, condition (financial or otherwise) or
prospects of the Business or the Acquired Assets or the ability of Seller to
consummate the transactions contemplated hereby (a "MATERIAL ADVERSE EFFECT").
No jurisdiction in which Seller is not qualified or licensed as a foreign
corporation has demanded or requested in writing that it qualify or become
licensed as a foreign corporation. Complete and accurate copies of the charter
documents and bylaws of Seller, with all amendments thereto to the date hereof,
have been furnished to Buyer or its representatives.


                                       2
<PAGE>

      2.2 Authorization. Seller has all requisite corporate power and authority
to enter into this Agreement and to consummate the transactions contemplated
hereby. This Agreement and all other agreements and instruments to which Seller
or Parent is a party and which are to be delivered in connection herewith
(collectively, the "TRANSACTION DOCUMENTS"), have been duly and validly approved
by the Board of Directors of Seller and by Parent, and no other corporate
proceedings on the part of Seller or Parent are necessary to approve this
Agreement and to consummate the transactions contemplated hereby and thereby.
This Agreement and the other Transaction Documents to which Seller or Parent is
a party have been duly executed and delivered by Seller and Parent, have been
effectively authorized by all necessary corporate and shareholder action and
constitute legal, valid and binding obligations of Seller and Parent.

      2.3 Acquired Assets.

            (a) Ownership. Seller is the lawful owner of or has the right and
title to use and transfer to Buyer each of the Acquired Assets. The Acquired
Assets are free and clear of all liens, mortgages, pledges, security interests,
restrictions, prior assignments, encumbrances, legal or equitable claims of
others and other claims of any kind (each a "LIEN"), except for: (i) liens for
taxes not yet payable and (ii) Liens listed on Schedule 2.3(a). The delivery to
Buyer of the Bill of Sale will vest good title to the Acquired Assets in Buyer,
free and clear of all Liens. There are no outstanding Contracts (as defined
below) of any nature obligating Seller or Parent to directly or indirectly
transfer any of the Acquired Assets or rights or interests therein to any Person
other than Buyer. For purposes of this Agreement, "PERSON" shall mean any
individual, partnership, joint venture, association, limited liability company,
corporation, trust, unincorporated organization, Governmental Authority (as
defined below), or other entity.

            (b) Condition of the Acquired Assets. All of the Acquired Assets are
in good operating condition and repair, ordinary wear and tear accepted. None of
the Acquired Assets is in need of repair or replacement other than as part of
routine maintenance in the ordinary course of business. The Acquired Assets are
sufficient to produce a catalog similar to the catalog used in the Business
during the past year and to enable the Buyer to distribute such catalog to the
customers of the Seller listed on the customer list included in the Acquired
Assets.

            (c) Ownership of Seller. Parent is the record and beneficial owner
of all of the issued and outstanding capital stock of Seller. There are no
Contracts relating to the issuance, sale or transfer of any voting or other
equity securities of Seller. For purposes of this Agreement, "CONTRACTS" means
all contracts, agreements and other instruments and understandings of any kind,
including without limitation, loan agreements, letters of credit, guarantees,
notes, leases, employee plans, and all amendments, supplements, modifications,
extensions, or renewals in respect of the foregoing.

      2.4 Proprietary Rights. Except as set forth on Schedule 2.4(a), to the
best of Seller's knowledge based upon due inquiry, Seller (i) owns and/or has
the right to use the formulations in the Bronson Products (as hereinafter
defined) (the "FORMULATIONS") or has the right to sell the Bronson Products;
(ii) owns and/or has the right to use the trade name "Bronson Laboratories";

<PAGE>

hereinafter defined), the Bronson Online website and the Bronson marketing
materials; and (vi) will transfer to Buyer, on the date hereof, the trademarks
listed on Schedule 2.4(b) and the Licenses listed on Schedule 2.11, to the
extent transferable. Parent is licensing to Buyer the Formulations (or the right
to use, manufacture or sell a Formulation) that Parent may possess to the extent
such Formulation is used in a Bronson Product and is set forth on Schedule
2.4(c) (the "LICENSED Products"). Except with respect to the Licensed Products,
Seller is conveying, transferring, assigning, selling and delivering to Buyer
its rights in the Formulations Seller uses in the Bronson Products, and all
proprietary rights listed in this Section 2.4, to the extent transferable by
Seller; it being expressly understood and agreed that, except as set forth in
this Section 2.4, neither Seller nor Parent is making and shall not be deemed to
make any representation or warranty concerning or relating to any Formulation,
or any part thereof. For purposes of this Agreement, "AFFILIATE" shall mean a
Person that directly, or indirectly through one or more intermediaries, controls
or is controlled by, or is under common control with, the Person specified. For
purposes of this Agreement, "BRONSON PRODUCTS" shall mean the Bronson branded
vitamins and nutritional supplements sold by Seller through the Business.

      2.5 No Conflict or Violation. The execution, delivery and performance by
Seller and Parent of this Agreement and the other Transaction Documents to be
delivered by Seller or Parent and the consummation of the transactions
contemplated hereby and thereby do not: (i) violate or conflict with any
provision of the charter documents or bylaws of Seller or Parent or any
resolution adopted by the board of directors or stockholders of Seller or
Parent; (ii) violate in any material respect any provision or requirement of any
domestic or foreign, federal, state, or local law, statute, judgment, order,
writ, injunction, decree, award, rule, or regulation of any Governmental Entity
applicable to Seller, Parent, the Business or the Acquired Assets; (iii)
violate, result in a material breach of, constitute (with due notice or lapse of
time or both) a default or cause any material obligation, penalty, premium or
right of termination to arise or accrue under any Seller Contract (as defined
below); or (iv) result in the creation or imposition of any Lien upon the
Acquired Assets. For purposes of this Agreement, "GOVERNMENTAL ENTITY" shall
mean any United States federal, state or local, or any foreign, government,
governmental, regulatory or administrative authority, agency or commission or
any court, tribunal, or judicial or arbitral body.

      2.6 Consents. Schedule 2.6 lists all consents and notices required (i) by
law, rule, regulation or order of any Governmental Entity or (ii) by the
provisions of any material contract to which Seller or Parent is a party or by
which their respective properties are bound to be obtained or given by or on
behalf of Seller or Parent in connection with the execution of this Agreement
and the other Transaction Documents and the consummation of the transactions
contemplated hereby and thereby. All such consents have been duly obtained and
are in full force and effect and all such notices have been given.

      2.7 Labor and Employment Matters. Schedule 2.7(a) lists all current
employees of Seller, including the current title and current compensation of
such employees. Except as set forth on Schedule 2.7(b), there is no employment
agreement, severance agreement, collective bargaining agreement or other labor
or employment contract to which Seller is a party or by which it is bound. No
petition has been filed by any employee or group of employees of Seller with any
labor relations board seeking recognition of a bargaining representative for
such employees. Seller has complied in all material respects with all applicable
laws, rules and


                                       4
<PAGE>

regulations relating to employment and termination of employment of employees,
including without limitation those related to wages, hours, collective
bargaining and the payment and withholding of taxes and other sums as required
by appropriate Governmental Entities and has withheld and paid to the
appropriate Governmental Entities or is holding for payment not yet due to such
Governmental Entities, all amounts required to be withheld from employees of
Seller and is not liable for any arrears of wages, taxes, penalties or other
sums for failure to comply with any of the foregoing. There is no unfair labor

Schedule 2.8, no claims have been filed with any Governmental Entity by any
employee listed on Schedule 4.3(b) alleging the breach of a fiduciary obligation
by Seller or Parent prior to the date hereof under any employee benefit plan

      2.9 Litigation. Except as set forth on Schedule 2.9, there are no claims,
actions, suits or proceedings of any nature pending or, to the knowledge of
Seller or Parent threatened, by or against Parent, Seller, the officers,
directors, employees, agents of Seller, or any of their respective Affiliates
involving, affecting or relating to the Acquired Assets or the transactions
contemplated by this Agreement. No Acquired Asset is subject to any order, writ,
judgment, award, injunction or decree of any Governmental Entity.

      2.10 Certain Contracts.

            (a) Schedule 2.10(a) lists all material Contracts to which Seller is
a party relating to, binding on or affecting any of the Acquired Assets,
including, without limitation, all: (i) supply, distribution or other Contracts
pursuant to which third parties are or will be entitled or obligated to purchase
or use any of the Acquired Assets; (ii) personal property leases or any
subleases relating thereto; (iii) Contracts limiting or restraining any of
Seller's employees from engaging or competing in any lines of business with any
Person; and (iv) other Contracts affecting the ownership of, title to, use of or
any leasehold or other interest in the Acquired Assets (each a "SELLER
CONTRACT," and collectively, the "SELLER CONTRACTS.") Schedule 2.10(b) lists all
Seller Contracts to be assumed by Buyer upon the Closing (the "ASSIGNED
CONTRACTS").

            (b) Each Seller Contract is valid, binding and enforceable against
the Seller in accordance with its terms, except as such enforceability may be
limited by general principles of equity and bankruptcy, insolvency,
reorganization and moratorium and other laws relating to creditors' rights, and
is in full force and effect. Seller has performed all material obligations
required to be performed by it under, and is not in material breach or in
default of, any Seller Contract, and no event has occurred which, with due
notice or lapse of time or both, would constitute such a material breach or
default.

<PAGE>

             (c) To the knowledge of Seller or Parent, without any independent
investigation, no other party to any Seller Contract is in material breach or in

lapse of time or both, would constitute such a material breach or default.

            (d) There are no material disputes with any party to any Seller
Contract, and to the knowledge of Seller or Parent, no party to any Seller
Contract has credibly threatened to cancel or terminate any Seller Contract,
whether as a result of the transactions contemplated by this Agreement or
otherwise.

            (e) To the knowledge of Seller or Parent, without any independent
investigation, no party to any Seller Contract has assigned any of its rights or
delegated any of its duties under such Seller Contract.

            (f) Neither the execution and delivery by Seller of this Agreement,
nor the consummation by Seller of the transactions contemplated herein in
accordance with the terms hereof, in any material respect, violates, or
conflicts with, or results in a breach of any provision of, or constitutes a
material default (or an event which, with notice or lapse of time or both, would
constitute a default) under, or results in the termination or in a right of
termination or cancellation of, or accelerates the performance required by, or
results in the triggering of any payment obligations under, or results in the
creation of any Lien upon any of the Acquired Assets under, or results in being
declared void, voidable, or without further binding effect, any of the terms,
conditions or provisions of any Seller Contract.

            (g) Seller has delivered to Buyer or its representatives true and
complete originals or copies of all the Seller Contracts and a copy of every
Material Notice received by Seller or Parent since January 1, 2001 with respect
to any of the Seller Contracts. For purposes hereof, "MATERIAL NOTICE" means

or materially modify a Seller Contract, but does not include routine
correspondence.

regulations, orders and other requirements of all Governmental Entities having
jurisdiction over it and its assets, properties and operations, including,
without limitation, all such laws, regulations, orders and requirements relating
to the Acquired Assets. Without limiting the foregoing, Seller has complied with
all orders, judgments and decrees of any Governmental Entity under the
Occupational Safety and Health Act and its state law equivalents that apply to
the Acquired Assets, except where failure to so comply would not have a Material
Adverse Effect. Seller has not received any notice of any actual, alleged,
possible or potential material violation of any such law, regulation, order or
other legal requirement from any Governmental Authority, and to Seller's
knowledge no event has occurred nor any circumstance exists that (with or
without notice or lapse of time) may constitute or result in a violation by
Seller of, or a failure on the part of Seller to comply with, any such law,
regulation, order or other legal requirement or may give rise to any obligation
on the part of Seller to undertake or bear all or any portion of the cost of any
remedial action of any nature.

presently conducted, except where the failure to have such License would not
have a material adverse effect on the Business. Seller has delivered to Buyer or

all amendments and modifications thereto. Schedule 2.12 identifies all Licenses

paid for by Seller and is valid, in full force and effect and not subject to any

safety or the environment (collectively, "ENVIRONMENTAL LAWS") and Seller has
obtained and maintained in effect all licenses, permits and other authorizations
or registrations relating to the Acquired Assets and the Facility required under
all Environmental Laws (collectively "ENVIRONMENTAL PERMITS") and is in material
compliance with all such Environmental Permits.

            (b) Seller has not performed, failed to perform or suffered any act
relating to the Acquired Assets which could reasonably be expected to give rise
to, or has otherwise incurred, material liability relating to the Acquired
Assets to any Person (governmental or not) under the Comprehensive Environmental
Response, Compensation and Liability Act, 42 U.S.C. Section 9601 et seq.
("CERCLA"), or any other Environmental Laws, nor has it received notice of any
such liability or any claim therefore.

corporate power and authority to carry on its business as it is now being
conducted and to own, lease or operate the Acquired Assets. Buyer is duly
qualified to do business and is in good standing in every jurisdiction in which
the character of the properties owned or leased by it or the nature of the
business conducted by it makes such qualification necessary, except where
failure to be so qualified has not and could not reasonably be expected to have
a Material Adverse Effect on the business, operations, assets, results of
operations, condition (financial or otherwise) or prospects of its business. No
jurisdiction in which Buyer is not qualified or licensed as a foreign
corporation has demanded or requested that it qualify or become licensed as a
foreign corporation.

      3.2 Authorization. Buyer has all requisite corporate power and authority
to enter into this Agreement and to consummate the transactions contemplated
hereby. This Agreement and the other Transaction Documents to which Buyer is a
party have been duly and validly approved by the Board of Directors of Buyer and
no other proceedings on the part of Buyer are necessary to approve this
Agreement and to consummate the transactions contemplated hereby and thereby.
This Agreement and the other Transaction Documents to which the Buyer is a party
have been (or upon execution by Buyer will have been) duly executed and
delivered by Buyer, have been effectively authorized by all necessary action of
Buyer, corporate or otherwise, and constitute (or upon execution will
constitute) legal, valid and binding obligations of Buyer.

      3.3 No Conflict or Violation. The execution, delivery and performance by
Buyer of this Agreement and the other Transaction Documents to be executed and
delivered by Buyer and the consummation of the transactions contemplated hereby
and thereby do not and will not: (i) violate or conflict with any provision of
the charter documents or bylaws of Buyer; or (ii) violate in any material
respect any provision or requirement of any domestic or foreign, national, state
or local law, statute, judgment, order, writ, injunction, decree, award, rule,
or regulation of any Governmental Entity applicable to Buyer.

      3.4 Consents. No consents or notices are required to be obtained or given
by or on behalf of Buyer in connection with the execution of this Agreement and
the other Transaction Documents and the consummation of the transactions
contemplated hereby and thereby.

the January catalog relating to the sale of the Bronson Products (the "JANUARY
CATALOG") and has approved the final form of the January Catalog, which was
printed and distributed to customers of Seller in December 2002.

      3.6 Brokers. No broker, finder, investment banker, or other Person is
entitled to any brokerage, finder's or other fee or commission in connection
with the transactions contemplated by this Agreement, based upon arrangements
made by or on behalf of Buyer.

4. CERTAIN UNDERSTANDINGS AND AGREEMENTS OF THE PARTIES.

      4.1   Tax Matters.

            (a) Seller and Buyer will each provide the other party with such
assistance as may reasonably be requested in connection with preparation of any
tax return, audit or other examination by any taxing authority or judicial or
administrative proceeding relating to liability for taxes related to or
attributable to the Acquired Assets (each, a "TAX RETURN", and collectively the
"TAX RETURNS"), will each retain and provide to the other party all records and
other information that may be relevant to any such Tax Return, audit or
examination, proceeding or determination and will each provide the other party
with any final determination of any such audit or examination, proceeding or
determination that affects any amount required to be shown on any such Tax
Return of the other party for any period. Without limiting the generality of the
foregoing, each of Buyer and Seller will retain, until the expiration of the
applicable statutes of limitation (including any extensions thereof) copies of
all such Tax Returns, supporting work schedules and other records relating to
tax periods or portions thereof ending on or prior to the Closing Date.

            (b) Notwithstanding any other provision of this Agreement, the
covenants set forth in this Section 4.1 shall survive until the expiration of
the respective statute of limitations applicable to the periods to which the
taxes referred to herein relate.

      4.2   Access to Records and Files.

            (a) Seller shall have the right for a period of five years following
the Closing Date to have reasonable access to such books, records and accounts,
correspondence, employment records and other similar information as are
transferred to Buyer pursuant to the terms of this Agreement for any lawful and
proper purpose. Buyer shall have the right for a period of five years following
the Closing Date to have reasonable access to those books, records and accounts,
correspondence, and other records which are retained by Seller pursuant to the
terms of this Agreement to the extent that any of the foregoing relate to the
Acquired Assets or to the extent that such access is required for any lawful and
proper purpose.

            (b) Buyer agrees that, in the event Seller receives written notice
of a claim relating to the Acquired Assets or any product manufactured or
distributed by Seller prior to the '


                                       9
<PAGE>

Closing Date, Buyer shall cooperate with Seller in all reasonable respects, at
Seller's cost, in the investigation, trial, defense and any appeal arising from
the matter from which such claim arose, including without limitation providing
Seller access to all information necessary for Seller's defense of such claim.

      4.3 Employment.

            (a) Except as set forth herein, Buyer shall not assume any
liabilities or obligations of Seller to any current or former employee of
Seller. Except as set forth in Section 4.3(b), Buyer shall not have any
liability or obligation to or in respect of any employee of Seller, including,
without limitation, any liability or obligation (i) to employ or engage any such
employee, (ii) arising from such employee's dismissal by Seller, whether or not
in connection with the transactions contemplated hereby, or any notice or
payment in lieu of notice required by applicable law in connection with such
dismissal, or (iii) in respect of any compensation (including severance payments
and accrued vacation or sick day payments), tenure, seniority, benefit or
welfare plan or arrangement of any kind.

            (b) Buyer agrees to offer employment or engagement to each of the
employees of Seller listed on Schedule 4.3. Except as otherwise specifically set
forth herein, the salaries, wages or compensation rates, medical insurance and
other benefits, and seniority and title of such employees shall be determined in
the sole discretion of Buyer. Notwithstanding the foregoing, Buyer agrees to
offer medical insurance to the employees of Seller hired by Buyer as soon as
permitted by its current insurance carrier that provides such plans to Buyer's
employees. At any time after the Closing, Buyer may offer employment or similar
engagements to any other former employee of Seller, notwithstanding the fact
that they were not offered employment as of the Closing Date. Seller shall have
no responsibility for any liabilities or obligations (except for any continuing
obligations of Seller required by law) with respect to any transferred
employee's employment by Buyer.

            (c) Buyer shall be obligated to comply with all applicable laws,
regulations and obligations under the Consolidated Omnibus Reconciliation Act of
1985, as amended, and any similar state law ("COBRA") for all employees of
Seller, and their respective spouses and eligible beneficiaries, hired by Buyer
on or after the date hereof.

      4.4 WARN Act. Prior to the Closing Date, Seller shall have full
responsibility for providing any notice to its employees and appropriate
government officials which may be required pursuant to the Worker Adjustment and
Retraining Notification Act of 1988, as amended (the "WARN ACT"), or any similar
state law with respect to any employees terminated by Seller. Seller will bear
any costs, obligations or liabilities which may accrue, prior to the Closing
Date, to such employees or any unit of local government under such Act or any
similar state law as a result of improper or untimely notice or other failure to
comply with such laws. Seller shall have no responsibility under the WARN Act
with respect to any employees of Seller employed by Buyer after the Closing
Date.

      4.5 Rights in "Bronson Laboratories, Inc.". Promptly after the Closing
Date, Seller will, and Parent will cause Seller to, change its name to Twinlab
Catalog Corp., or such other name not confusingly similar with "Bronson
Laboratories, Inc.", which does not contain the


                                       10
<PAGE>

word "Bronson", as may be acceptable to Buyer. From and after the Closing Date,
neither Parent, Seller nor any of their Affiliates will employ the term
"Bronson" or "Bronson Laboratories" or a confusingly similar term in its
business, except in connection with documents referencing the fact that Seller
was previously a wholly owned subsidiary of Parent. From and after the Closing
Date, Seller shall provide Buyer all documents of assignment reasonably
requested by Buyer to transfer to Buyer all of Seller's right, title and
interest in the name "Bronson Laboratories."

      4.6 Expenses Related to January Catalog. Buyer shall have full
responsibility for the payment of all fees, costs and expenses relating to the
printing and production of the January Catalog. Buyer and Seller agree that
Seller shall be responsible for the payment of the postage fees of mailing the
January Catalog (the "POSTAGE FEES"), only to the extent such Postage Fees are
equal to or less than $30,000. Buyer agrees that it shall reimburse Seller for
any Postage Fees in excess of $30,000, which amount, if any, is being paid on
the date hereof.

      4.7 Non-Competition and Non-Solicitation.

            (a)   Non-Competition

                  (i) Until the date that is thirty (30) months after the
Closing Date, Seller and Parent shall not, directly or indirectly, on their
behalf or on behalf of others, own, manage, operate, control or participate in
the ownership, management, operation or control of, or provide consulting
services to, any other corporation, firm, business, partnership, person,
proprietorship or other entity engaged in or carrying on the Business (other
than the business of selling branded vitamins and nutritional supplements via
the internet channel of distribution, which is governed exclusively by the
provisions of clause (ii) hereof).

                  (ii) Until the date that is one year after the Closing Date,
Seller and Parent shall not, directly or indirectly, on their behalf or on
behalf of others, own, manage, operate, control or participate in the ownership,
management, operation or control of, or provide consulting services to, any
other corporation, firm, business, partnership, person, proprietorship or other
entity engaged in or carrying on the business of selling branded vitamins and
nutritional supplements (other than any branded products currently sold by
Parent or any successor in interest of Parent) via the internet channel of
distribution.

                  (iii) The provisions of clause (i) of this Section 4.7(a)
shall terminate on or as of the date that is six months after the Closing Date
in the event of the sale, merger, consolidation, disposition or sale of all or
substantially all of the assets of Parent to, with or into any other Person.
However, at no time subsequent to the date hereof shall Seller or Parent or any
successor in interest of Seller or Parent, directly or indirectly, use the name
"Bronson" or any Bronson Customer List (as defined below) in connection with the
business activities of Seller or Parent, except as provided for herein.

            (b) Until the first anniversary of the Closing Date, Seller and
Parent shall not, and shall cause their Affiliates not to, directly or
indirectly, on their behalf or on behalf of others, hire or attempt to hire, or
cause any other Person to hire or attempt to hire, any employee of Buyer
(including without limitation persons employed or engaged by Seller before the
Closing


                                       11
<PAGE>

Date who accept offers of employment with Buyer), or directly or
indirectly entice or solicit or seek to induce or influence any of such
employees to leave their employment or engagement with Buyer.

            (c) Except for the employees listed on Schedule 4.3, until the first
anniversary of the Closing Date, Buyer shall not, and shall cause its Affiliates
not to, directly or indirectly, on its behalf or on behalf of others, hire or
attempt to hire, or cause any other Person to hire or attempt to hire, any
employee of Parent or its Affiliates, or directly or indirectly entice or
solicit or seek to induce or influence any of such employees to leave their
employment or engagement with Parent or its Affiliates.

            (d) The covenants set forth in subsections (a), (b) and (c) above
shall be read and interpreted with every reasonable inference given to their
enforceability. However, if any term, provision or condition of such covenants
is held by a court or arbitrator to be invalid, void or unenforceable, the
remainder of the provisions thereof shall remain in full force and effect and
shall in no way be affected, impaired or invalidated. If a court or arbitrator
should determine any of such covenants are unenforceable because of
over-breadth, then the court or arbitrator shall modify such covenant so as to
make it enforceable to the fullest extent the court or arbitrator deems
reasonable and enforceable under the prevailing circumstances.

      4.8 Inventory Bill of Sale. As of the date hereof and as a condition to
the purchase of the Acquired Assets, Seller shall have sold and Buyer shall have
purchased certain inventory of the Seller pursuant to a bill of sale (the
"INVENTORY BILL OF SALE") in the form of Exhibit B.

      4.9 Transition Services Agreement. As of the date hereof, Buyer and Seller
shall enter into a Transition Services Agreement, in the form of Exhibit C,
setting forth the terms by which Seller will assist Buyer in the continuance of
the Business for a period of time sufficient to allow Buyer to relocate the
Acquired Assets to the Buyer's New York facility.

      4.10 Bronson Customer List. Seller and Parent agree that, subsequent to
the Closing Date, they shall not use, maintain, copy or distribute, or permit
any Affiliate, officer or director of Seller or Parent to use maintain, copy or
distribute, for any purpose relating to the Business or otherwise, any customer
list of Seller being sold to Buyer pursuant to this Agreement (each, a "Bronson
Customer List"). Seller and Parent agree that, subsequent to the date hereof,
they shall not maintain any copies of any Bronson Customer List, in any form
whatsoever, except to the extent necessary to perform their obligations under
the Transition Services Agreement, or as required by law.

      4.11 Further Assurances. Upon the reasonable request of a party or parties
hereto at any time after the Closing Date, the other party or parties shall
forthwith execute and deliver such further instruments of assignment, transfer,
conveyance, endorsement, direction or authorization and other documents as the
requesting party or parties or its or their counsel may reasonably request in
order to perfect title of Buyer and its successors and assigns to the Acquired
Assets or otherwise to effectuate the purposes of this Agreement (including with

      5.4   Indemnification Procedure.

            (a) Notice. Whenever any claim shall arise for indemnification
hereunder (a "CLAIM"), the party entitled to indemnification (the "INDEMNITEE")
shall promptly give written notice to the party obligated to provide indemnity
(the "INDEMNITOR") with respect to the Claim after the receipt by the Indemnitee
of reliable information of the facts constituting the basis for the Claim; but
the failure to timely give such notice shall not relieve the Indemnitor from any
obligation under this Agreement, except to the extent, if any, that the
Indemnitor is materially prejudiced thereby.

            (b) Third-Party Claims.

                  (i) Upon receipt of written notice from the Indemnitee of a
            Claim, the Indemnitor shall promptly pay the amount of the Claim,
            unless the Indemnitor shall dispute the Claim or the amount thereof,
            and the Indemnitor may provide counsel (such counsel subject to the
            reasonable approval of the Indemnitee) to defend the Indemnitee
            against the matter from which the Claim arose, at the Indemnitor's
            sole cost, risk and expense. If the Indemnitor assumes such defense,
            the Indemnitee shall cooperate in all reasonable respects, at the
            Indemnitor's sole cost, risk and expense, with the Indemnitor in the
            investigation, trial, defense and any appeal arising from the matter
            from which the Claim arose; provided, however, that the Indemnitee
            may (but shall not be obligated to) participate in any such
            investigation, trial, defense and any appeal arising in connection
            with the Claim at the sole cost of the Indemnitee. After notice from
            the Indemnitor to the Indemnitee of the Indemnitor's election to
            assume the defense, compromise or settlement of such Claim, the
            Indemnitor shall not, as long as it diligently conducts such
            defense, be liable to the Indemnitee for any fees of other counsel
            or any other expenses with respect to the defense of such Claim, in
            each case subsequently incurred by the Indemnitee in connection with
            the defense, compromise, or settlement of the Claim. The Indemnitor
            shall have the right to elect to settle any Claim for monetary
            damages without the Indemnitee's consent, only if the settlement
            includes a complete release of the Indemnitee. If the settlement
            does not include such a release, it will be subject to the consent
            of the Indemnitee, which consent shall not be unreasonably withheld.
            The Indemnitor may not admit any liability of the Indemnitee or
            waive any of the Indemnitee's rights without the Indemnitee's prior
            written consent, which consent shall not be unreasonably withheld.
            If the subject of any Claim results in a judgment or settlement, the
            Indemnitor shall promptly pay such judgment or settlement.

                   (ii) If the Indemnitor fails to promptly assume the defense
            of the subject of any Claim in accordance with the terms of Section
            5.4(b)(i), or fails diligently to prosecute such defense, the
            Indemnitee may defend against the subject of the Claim, and the
            Indemnitor shall be responsible for the reasonable expenses incurred
            by the Indemnitee in connection with such defense, including
            employment of one counsel reasonably satisfactory to the Indemnitee.
            If the Indemnitee defends the subject of a Claim in accordance with

the Bronson Laboratories Inventory Summary, attached hereto as Schedule A (the
"INVENTORY"), to have and to hold the same unto Buyer and the heirs, successors
and assigns of Buyer forever.

            1.2 The Inventory Purchase Price shall be adjusted so that, to the
extent that the value of the Inventory, as determined on a cost basis as agreed
to by the parties (the "BOOK VALUE") on the date hereof, is greater than
$2,000,000, the Inventory Purchase Price shall be increased, on a dollar for
dollar basis, by an amount equal to the difference between the Book Value and
$2,000,000 (the "PURCHASE PRICE INCREASE"), such Purchase Price Increase shall
in no event exceed $500,000. Buyer shall have 90 days from the Closing Date to
pay to Seller, by wire transfer of immediately available funds, the amount, if
any, of the Purchase Price Increase. To the extent that the Book Value on the
date hereof is less than $2,000,000, the Inventory Purchase Price shall be
reduced, on a dollar for dollar basis, by an amount equal to the difference
between $2,000,000 and the Book Value (the "PURCHASE PRICE REDUCTION"). Seller
shall promptly reimburse to Buyer, by wire transfer of immediately available
funds, the amount, if any, of the Purchase Price Reduction. The parties agree
that, within fifteen business days of the Closing Date (the "VALUATION PERIOD"),
they shall determine the Book Value in accordance with procedures to be agreed
upon by the parties. To the extent that the parties are unable to agree upon the
Book Value during the Valuation Period, an independent accounting firm selected
by, and mutually acceptable to, and whose fees and expenses shall be shared
equally by, Seller and Buyer shall determine the Book Value. Seller and Buyer
shall be bound by the Book Value as determined by the independent accounting
firm. The independent accounting firm shall make the determination of the Book
Value within thirty Business Days of the selection of the independent accounting
firm.

            1.3 Seller hereby constitutes and appoints Buyer, its successors and
assigns, as Seller's true and lawful attorney with full power of substitution in
Seller's name and stead, on behalf of and for the benefit of Buyer, its
successors and assigns, solely to demand and receive any and all of the
Inventory transferred hereunder and to give receipts and releases for and in
respect of the same, and any part thereof, and from time to time to institute
and prosecute in Seller's name, or otherwise, for the benefit of Buyer, its
successors and assigns, any and all proceedings at law, in equity or otherwise,
which Buyer, its successors or assigns, may deem proper for the collection or
reduction to possession of any of the Inventory transferred hereunder or for the
collection and enforcement of any claim or right of any kind hereby sold,
conveyed, transferred, assigned or delivered, or intended so to be, and to do
all other acts and things in relation to the Inventory that Buyer, its
successors or assigns, shall deem desirable. Seller hereby declares that the
foregoing powers are coupled with an interest and are and shall be irrevocable
by Seller in any manner or for any reason whatsoever.
