      9. Resignation and Removal of Escrow Agent. Escrow Agent may resign from
the performance of its duties hereunder at any time by giving thirty (30) days'

and duties of the retiring Escrow Agent, and the retiring Escrow Agent shall be

Escrow Agent's sole responsibility shall be for the safekeeping, investment, and
disbursement of the Escrow Funds in accordance with the terms of this Agreement.
Escrow Agent shall have no implied duties or obligations and shall not be
charged with knowledge or notice or any fact or circumstance not specifically
set forth herein. Escrow Agent may rely upon any instrument, not only as to its
due execution, validity and effectiveness, but also as to the truth and accuracy
of any information contained herein, which Escrow Agent shall in good faith
believe to be genuine, to have been signed or presented by the person or parties
purporting to sign the same and conform to the provisions of this Agreement. In
no event shall Escrow Agent be liable for incidental, indirect, special, and
consequential or punitive damages. Escrow Agent shall not be obligated to take
any legal action or commence any proceeding in connection with the Escrow Funds,
any account in which Escrow Funds are deposited, this Agreement or the Purchase
Agreement, or to appear in, prosecute or defend any such legal action or
proceeding. Escrow Agent may consult legal counsel selected by it in any event
of any dispute or question as to construction of any of the provisions hereof or
of any other agreement or its duties hereunder, or relating to any dispute
involving any party hereto, and shall incur no liability and shall be fully
indemnified from any liability whatsoever in acting in accordance with the
opinion or instructions of such counsel. The Company and the Investor(s) jointly
and severally shall promptly pay, upon demand, the reasonable fees and expenses
of any such counsel.

      b. Escrow Agent is hereby authorized, in its sole discretion, to comply
with orders issued or process entered by any court with respect to the Escrow
Funds, without determination by Escrow Agent of such court's jurisdiction in the
matter. If any portion of the Escrow Funds is at any time attached, garnished or
levied upon under any court order, or in case the payment, assignment, transfer,
conveyance or delivery of any such property shall be stayed or enjoined by any
court order, or in any case any order judgment or decree shall be made or
entered by any court affecting such property or any part thereof, then and in
any such event, Escrow Agent is authorized, in its sole discretion, to rely upon
and comply with any such order, writ judgment or decree which it is advised by
legal counsel selected by it, binding upon it, without the need for appeal or
other action; and if Escrow Agent complies with any such order, writ, judgment
or decree, it shall not be liable to any of the parties hereto or to any other
person or entity by reason of such compliance even though such order, writ
judgment or decree may be subsequently reversed, modified, annulled, set aside
or vacated.

      11. Indemnification of Escrow Agent. From and at all times after the date
of this Agreement, the parties jointly and severally, shall, to the fullest
extent permitted by law and to the extent provided herein, indemnify and hold
harmless Escrow Agent and each director, officer, employee, attorney, agent and
affiliate of Escrow Agent (collectively, the "Indemnified Parties") against any
and all actions, claims (whether or not valid), losses, damages, liabilities,
costs and expenses of any kind or nature whatsoever (including without
limitation reasonable attorney's fees, costs and expenses) incurred by or
asserted against any of the Indemnified Parties from and after the date hereof,
whether direct, indirect or consequential, as a result of or arising from or in
any way relating to any claim, demand, suit, action, or proceeding (including
any inquiry or investigation) by any person, including without limitation the
parties to this Agreement, whether threatened or initiated, asserting a claim
for any legal or equitable remedy against any person under any statute or
regulation, including, but not limited to, any federal or state securities laws,
or under any common law or equitable cause or otherwise, arising from or in
connection with the negotiation, preparation, execution, performance or failure
of performance of this Agreement or any transaction contemplated herein, whether
or not any such Indemnified Party is a party to any such action or proceeding,
suit or the target of any such inquiry or investigation; provided, however, that
no Indemnified Party shall have the right to be indemnified hereunder for
liability finally determined by a court of competent jurisdiction, subject to no
further appeal, to have resulted from the gross negligence or willful misconduct
of such Indemnified Party. If any such action or claim shall be brought or
asserted against any Indemnified Party, such Indemnified Party shall promptly
notify the Company and the Investor(s) hereunder in writing, and the Investor(s)
and the Company shall assume the defense thereof, including the employment of
counsel and the payment of all expenses. Such Indemnified Party shall, in its
sole discretion, have the right to employ separate counsel (who may be selected
by such Indemnified Party in its sole discretion) in any such action and to
participate and to participate in the defense thereof, and the fees and expenses
of such counsel shall be paid by such Indemnified Party, except that the
Investor(s) and/or the Company shall be required to pay such fees and expense if
(a) the Investor(s) or the Company agree to pay such fees and expenses, or (b)
the Investor(s) and/or the Company shall fail to assume the defense of such
action or proceeding or shall fail, in the sole discretion of such Indemnified
Party, to employ counsel reasonably satisfactory to the Indemnified Party in any
such action or proceeding, (c) the Investor(s) and the Company are the plaintiff
in any such action or proceeding or (d) the named or potential parties to any
such action or proceeding (including any potentially impleaded parties) include
both the Indemnified Party, the Company and/or the Investor(s) and the
Indemnified Party shall have been advised by counsel that there may be one or
more legal defenses available to it which are different from or additional to
those available to the Company or the Investor(s). The Investor(s) and the
Company shall be jointly and severally liable to pay fees and expenses of
counsel pursuant to the preceding sentence, except that any obligation to pay
under clause (a) shall apply only to the party so agreeing. All such fees and
expenses payable by the Company and/or the Investor(s) pursuant to the foregoing
sentence shall be paid from time to time as incurred, both in advance of and
after the final disposition of such action or claim. The obligations of the
parties under this section shall survive any termination of this Agreement, and
resignation or removal of the Escrow Agent shall be independent of any
obligation of Escrow Agent.

      The parties agree that neither payment by the Company or the Investor(s)
of any claim by Escrow Agent for indemnification hereunder shall impair, limit,
modify, or affect, as between the

                                        6

to officers, directors, employees and others who render services to NUTRITION

strengthen the desire of such persons to join and remain in the employ of the
Corporation, or otherwise render services to the Corporation, and stimulate
their efforts on behalf of the Corporation.

      1.2. Term. No Award shall be granted under the Plan after the close of
business on the day immediately preceding the 10-year anniversary of the

Awards made under the Plan prior to such termination of the Plan shall remain in
effect until such Awards have been satisfied or terminated in accordance with
the Plan and the terms of such Awards.

      1.3. Shares Subject to the Plan. Subject to adjustments as provided in
Article IX, the number of shares of Stock that may be delivered, purchased or
used for reference purposes (with respect to SARs or Stock Units) with respect
to Awards granted under the Plan shall be 5,000,000 shares. If any Award, or
portion of an Award, under the Plan expires or terminates unexercised, becomes
unexercisable or is forfeited or otherwise terminated, surrendered or canceled
as to any shares without the delivery of shares of Stock or other consideration,
the shares subject to such Award shall thereafter be available for further

of grant.

Administrator's determinations under the Plan (including without limitation
determinations of the persons to receive Awards, the form, amount and timing of
such Awards, the terms and provisions of such Awards and the agreements

the Plan, whether or not such persons are similarly situated.

      3.2. Duties. The Administrator shall have full power and authority to
administer and interpret the Plan and to adopt such rules, regulations,
agreements, guidelines and instruments for the administration of the Plan and
for the conduct of its business as the Administrator deems necessary or
advisable, all within the Administrator's sole and absolute discretion. The

limited to, the authority to:

      3.2.1. construe the Plan and any Award under the Plan;

cashless exercise of Awards and/or reduction in the exercise price of
outstanding Awards) and to approve the form of written instrument evidencing
Awards;

      3.2.5. accelerate the time or times at which an Award becomes vested or
when an Award may be exercised or becomes payable and to waive or accelerate the
lapse, in whole or in part, of any restriction or condition with respect to such
Award, including, but not limited to, any restriction or condition with respect
to the vesting or exercisability of an Award following a Participant's
termination of employment or death;

      3.2.6. impose limitations on Awards, including limitations on transfer and

<PAGE>

4.    ARTICLE IV Eligibility and Participation

      4.1. Eligibility. The persons eligible to participate in the Plan are
officers, directors, employees of the Corporation or its Subsidiaries and others
that render services to the Corporation or its Subsidiaries.

5.    ARTICLE V Stock Options

      5.1. General. Subject to the other applicable provisions of the Plan, the
Administrator may from time to time grant to eligible Participants Awards of
ISOs or NSOs. The ISO or NSO Awards granted shall be subject to the following
terms and conditions.

      5.2. Grant of Option. The grant of an Option shall be evidenced by a Grant
Agreement, executed by the Corporation and the Participant, describing the
number of shares of Stock subject to the Option, whether the Option is an ISO or
NSO, the Exercise Price of the Option, the vesting period for the Option and
such other terms and conditions that the Administrator deems, in it sole
discretion, to be appropriate, provided that such terms and conditions are not
inconsistent with the Plan.

      5.3. Price. The price per share payable upon the exercise of each Option
(the "Exercise Price") shall be determined by the Administrator and set forth in
the Grant Agreement; provided, however, that in the case of ISOs, the Exercise
Price shall not be less than 100% of the Fair Market Value of the shares on the
Grant Date.

      5.4. Payment. Options may be exercised in whole or in part by payment of
the Exercise Price of the shares to be acquired in accordance with the
provisions of the Grant Agreement, and/or such rules and regulations as the
Administrator may prescribe, and/or such determinations, orders, or decisions as
the Administrator may make.

      5.5. Terms of Options. The term during which each Option may be exercised
shall be determined by the Administrator; provided, however, that in no event
shall an ISO be exercisable more than ten years from the date it is granted.

      5.6. Reload Options. The terms of an Option may provide for the automatic
grant of a new Option Award when the Exercise Price of the Option and/or any
related tax withholding obligation is paid by tendering shares of Stock.

      5.7. Restrictions on ISOs. ISO Awards granted under the Plan shall comply
in all respects with Code section 422 and, as such, shall meet the following
additional requirements:

      5.7.1. Grant Date. An ISO must be granted within ten (10) years of the
earlier of the Plan's adoption by the Board of Directors or approval by the
Corporation's shareholders.

<PAGE>

      5.7.2. Exercise Price and Term. The Exercise Price of an ISO shall not be
less than 100% of the Fair Market Value of the shares on the date the Option is
granted and the term of the Option shall not exceed ten (10) years.
Notwithstanding the immediately preceding sentence, the Exercise Price of any
ISO granted to a Participant who owns, within the meaning of Code section
422(b)(6), after application of the attribution rules in Code section 424(d),
more than ten percent (10%) of the total combined voting power of all classes of
shares of the Corporation, or its Parent or Subsidiary corporations, shall not
be less than 110% of the Fair Market Value of the Stock on the Grant Date and
the term of such ISO shall not exceed five (5) years.

      5.7.3. Maximum Grant. The aggregate Fair Market Value (determined as of
the Grant Date) of shares of Stock with respect to which all ISOs first become
exercisable by any Participant in any calendar year under this or any other plan
of the Corporation and its Parent and Subsidiary corporations may not exceed
$100,000 or such other amount as may be permitted from time to time under Code
section 422. To the extent that such aggregate Fair Market Value shall exceed
$100,000, or other applicable amount, such Options shall be treated as NSOs. In
such case, the Corporation may designate the shares of Stock that are to be
treated as stock acquired pursuant to the exercise of an ISO by issuing a
separate certificate for such shares and identifying the certificate as ISO
shares in the stock transfer records of the Corporation.

      5.7.4. Participant. ISOs shall only be issued to employees of the
Corporation, or of a Parent or Subsidiary of the Corporation.

      5.7.5. Tandem Options Prohibited. An ISO may not be granted in tandem with
a NSO in such a manner that the exercise of one affects a Participant's right to
exercise the other.

      5.7.6. Designation. No option shall be an ISO unless so designated by the
Administrator at the time of grant or in the Grant Agreement evidencing such
Option.

      5.8. Exercisability. Options shall be exercisable as provided in the Grant
Agreement.

      5.9. Transferability. ISOs shall be non-transferable. Except as provided
in the Grant Agreement, NSOs shall not be assignable or transferable by the
Participant, except by will or by the laws of descent and distribution.

6.    ARTICLE VI Stock Appreciation Rights

      6.1. Award of SARs. Subject to the other applicable provisions of the
Plan, the Administrator may at any time and from time to time grant SARs to
eligible Participants, either on a free-standing basis (without regard to or in
addition to the grant of an Option) or on a tandem basis (related to the grant
of an underlying Option).

      6.2. Restrictions on Tandem SARs. ISOs may not be surrendered in
connection with the exercise of a tandem SAR unless the Fair Market Value of the
Stock subject to the ISO is greater than the Exercise Price for such ISO. SARs
granted in tandem with Options shall be exercisable only to the same extent and
subject to the same conditions as the related Options are exercisable. The
Administrator may, in its discretion, prescribe additional conditions to the
exercise of any such tandem SAR.

<PAGE>

      6.3. Amount of Payment Upon Exercise of SARs. A SAR shall entitle the
Participant to receive, subject to the provisions of the Plan and the Grant
Agreement, a payment having an aggregate value equal to the product of (i) the
excess of (A) the Fair Market Value on the exercise date of one share of Stock
over (B) the base price per share specified in the Grant Agreement, times (ii)
the number of shares specified by the SAR, or portion thereof, which is
exercised. In the case of exercise of a tandem SAR, such payment shall be made
in exchange for the surrender of the unexercised related Option (or any portions
thereof which the Participant from time to time determines to surrender for this
purpose).

      6.4. Form of Payment Upon Exercise of SARs. Payment by the Corporation of
the amount receivable upon any exercise of a SAR may be made by the delivery of
Stock or cash, or any combination of Stock and cash, as determined in the sole
discretion of the Administrator.

      6.5. Transferability. SARs shall be transferable only as provided in the
Grant Agreement.

7.    ARTICLE VII; Restricted Stock and Stock Units

      7.1. Grants. Subject to the other applicable provisions of the Plan, the
Administrator may grant Restricted Stock or Stock Units to Participants in such
amounts and for such consideration, including no consideration or such minimum
consideration as may be required by law, as it determines. Such Awards shall be
made pursuant to a Grant Agreement.

      7.2. Terms and Conditions. A Restricted Stock Award entitles the recipient
to acquire shares of Stock and a Stock Unit Award entitles the recipient to be
paid the Fair Market Value of the Stock on the exercise date. Stock Units may be
settled in Stock, cash or a combination thereof, as determined by the
Administrator. Restricted Stock Awards and Stock Unit Awards are subject to
vesting periods and other restrictions and conditions as the Administrator may
include in the Grant Agreement.

      7.3. Restricted Stock.

      7.3.1. The Grant Agreement for each Restricted Stock Award shall specify
the applicable restrictions on such shares of Stock, the duration of such
restrictions, and the times at which such restrictions shall lapse with respect
to all or a specified number of shares of Stock that are part of the Award.
Notwithstanding the foregoing, the Administrator may reduce or shorten the
duration of any restriction applicable to any shares of Stock awarded to any
Participant under the Plan.

      7.3.2. Share certificates with respect to restricted shares of Stock may
be issued at the time of grant of the Restricted Stock Award, subject to
forfeiture if the restrictions do not lapse, or upon lapse of the restrictions.
If share certificates are issued at the time of grant of the Restricted Stock
Award, the certificates shall bear an appropriate legend with respect to the
restrictions applicable to such Restricted Stock Award (as described in Section
11.1) or, alternatively, the Participant may be required to deposit the
certificates with the Corporation during the period of any restriction thereon
and to execute a blank stock power or other instrument of transfer.

<PAGE>

      7.3.3. The extent of the Participant's rights as a shareholder with
respect to the Restricted Stock shall be specified in the Grant Agreement.

      7.4. Stock Units.

      7.4.1. The grant of Stock Units shall be evidenced by a Grant Agreement
that states the number of Stock Units evidenced thereby and the terms and
conditions of such Stock Units.

      7.4.2. Stock Units may be exercised in the manner described in the Grant
Agreement.

      7.4.3. The extent of the Participant's rights as a shareholder with
respect to the Stock Units shall be specified in the Grant Agreement.

      7.5. Transferability. Unvested Restricted Stock Awards or Stock Units may
not be sold, assigned, transferred, pledged or otherwise encumbered or disposed
of except as specifically provided in the Grant Agreement.

8.    ARTICLE VIII Tax Withholding

      8.1. Corporation's Right to Demand Payment for Withholding.

      8.2. Subject to subparagraph 8.3, as a condition to taking any action
otherwise required under the Plan or any Grant Agreement, the Corporation shall
have the right to require assurance that the Participant will remit to the
Corporation when required an amount sufficient to satisfy federal, state and
local tax withholding requirements. The Administrator may permit such
withholding obligations to be satisfied through cash payment by the Participant,
through the surrender of shares of Stock which the Participant already owns or
through the surrender of shares of Stock to which the Participant is otherwise
entitled under the Plan or through any other method determined by the
Administrator.

      8.3. If a Participant makes a disposition of shares of Stock acquired upon
the exercise of an ISO within either two (2) years after the Option was granted
or one (1) year after its exercise by the Participant, the Participant shall
promptly notify the Corporation and the Corporation shall have the right to
require the Participant to pay to the Corporation an amount sufficient to
satisfy federal, state and local tax withholding requirements.

9.    ARTICLE IX Corporate Transactions

      9.1. Adjustments Due to Special Circumstances.

<PAGE>

      9.1.1. In the event of any change in the capital structure or business of
the Corporation by reason of any stock dividend or extraordinary dividend, stock
split or reverse stock split, recapitalization, reorganization, merger,
consolidation, split-up, combination or exchange of shares, non-cash
distributions with respect to its outstanding Stock, reclassification of the
Corporation's capital stock, any sale or transfer of all or part of the
Corporation's assets or business, or any similar change affecting the
Corporation's capital structure or business or the capital structure of any
business of any Subsidiary, as determined by the Administrator, if the
Administrator determines that an adjustment is equitable, then the Administrator
may make such adjustments as it deems equitable with respect to the Plan and
Awards, including, without limitation, in: (i) the number of shares of Stock
that can be granted or used for reference purposes pursuant to the Plan; (ii)
the number and kind of shares or other securities subject to any then
outstanding Awards under the Plan; and (iii) the exercise price, base price, or
purchase price applicable to outstanding Awards under the Plan. The adjustment
by the Administrator shall be final, binding and conclusive.

      9.1.2. The Administrator may cancel outstanding Awards, but not
outstanding Stock or Restricted Stock Awards, in connection with any merger,
consolidation of the Corporation, or any sale or transfer of all or part of the
Corporation's assets or business, or any similar event. The Administrator may
determine to pay no compensation whatsoever for any canceled Awards that are not
in-the-money (as hereinafter defined) or for any canceled Awards to the extent
not vested. The Corporation shall provide payment in cash or other property for
the in-the-money value of the vested portion of Awards that are in-the-money and
that are canceled as aforesaid. Awards are "in-the-money" only to the extent of
their then realizable market value, without taking into account the potential
future increase in the value of the Award (whether under Black-Scholes-type
formulas or otherwise). The opinion by the Administrator of the in-the-money
value of any Award shall be final, binding and conclusive.

      9.2. Substitution of Options. In the event that, by reason of a corporate
merger, consolidation, acquisition of property or stock, separation,
reorganization or liquidation, the Board shall authorize the issuance or
assumption of a stock option or stock options in a transaction to which Code
section 424(a) applies, then, notwithstanding any other provision of the Plan,
the Administrator may grant options upon such terms and conditions as it may
deem appropriate for the purpose of assumption of the old option, or
substitution of a new option for the old option, in conformity with the
provisions of Code section 424(a) and the rules and regulations thereunder, as
they may be amended from time to time.

<PAGE>

10.   ARTICLE X Amendment and Termination

      10.1. Amendment. The Board may amend the Plan at any time and from time to
time, provided that (i) no amendment shall deprive any person of any rights
granted under the Plan before the effective date of such amendment, without such
person's consent; and (ii) amendments may be subject to shareholder approval to
the extent needed to comply with applicable law and stock exchange requirements.

      10.2. Termination. The Board reserves the right to terminate the Plan in
whole or in part at any time, without the consent of any person granted any
rights under the Plan.

11.   ARTICLE XI Miscellaneous

      11.1. Restrictive Legends. The Corporation may at any time place legends
referencing any restrictions described in the Grant Agreement and any applicable
federal or state securities law restrictions on all certificates representing
shares of Stock underlying an Award.

      11.2. Compliance with Governmental Regulations. Notwithstanding any
provision of the Plan or the terms of any Grant Agreement entered into pursuant
to the Plan, the Corporation shall not be required to issue any shares hereunder
prior to registration of the shares subject to the Plan under the Securities Act
of 1933, as amended, or the Securities Exchange Act of 1934, as amended, if such
registration shall be necessary, or before compliance by the Corporation or any
Participant with any other provisions of either of those acts or of regulations
or rulings of the Securities and Exchange Commission thereunder, or before
compliance with other federal and state laws and regulations and rulings
thereunder, including the rules of any applicable securities exchange or
quotation system.

      11.3. No Guarantee of Employment. Participation in this Plan shall not be
construed to confer upon any Participant the legal right to be retained in the
employ of the Corporation or give any person any right to any payment
whatsoever, except to the extent of the benefits provided for hereunder.

      11.4. Governing Law. The provisions of this Plan shall be governed by,
construed and administered in accordance with applicable federal law; provided,
however, that to the extent not in conflict with federal law, this Plan shall be
governed by, construed and administered under the laws of Delaware, other than
its laws respecting choice of law.

      11.5. Severability. If any provision of the Plan shall be held invalid,
the remainder of this Plan shall not be affected thereby and the remainder of
the Plan shall continue in force.
