THIS OPTION HAS BEEN ISSUED PURSUANT TO EXEMPTIONS FROM THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND THE
QUALIFICATION REQUIREMENTS OF APPLICABLE STATE SECURITIES LAWS (THE "LAWS"). IT
IS UNLAWFUL TO EXERCISE, SELL, PLEDGE OR OTHERWISE DISPOSE OF THIS OPTION, OR
ANY INTEREST THEREIN, OR RECEIVE ANY CONSIDERATION THEREFORE, IN THE ABSENCE OF

LAWS, UNLESS EXEMPTIONS FROM SUCH REGISTRATION AND QUALIFICATION REQUIREMENTS
ARE AVAILABLE.

THIS OPTION MAY BE EXERCISED ONLY IN ACCORDANCE WITH THE TERMS OF THIS STOCK
OPTION AGREEMENT.            ----

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

                                THE RICEX COMPANY

                      NON-STATUTORY STOCK OPTION AGREEMENT
                      ------------------------------------

         The RiceX Company, a Delaware corporation (the "Company"), hereby
grants to Terrence Barber (the "Optionee"), an option (the "Option") to purchase
up to 300,000 shares ("Shares") of Common Stock, per value $.001, of the Company
(the "Common Stock") at an exercise price (the "Exercise Price") equal to
fifteen cents ($.15) per share, in all respects subject to the terms,
definitions and provisions of this Non-Statutory Stock Option Agreement (the
"Agreement").

         1.   NATURE OF THE OPTION. The Option is intended to be a nonstatutory
option and not an incentive stock option within the meaning of Section 422 of
the Internal Revenue Code of 1986, as amended (the "Code").

         2.   PAYMENT OF EXERCISE PRICE.

              (a)  METHOD OF PAYMENT. Payment of the Exercise Price for shares
purchased upon exercise of the Option shall be made (i) by delivery to the
Company of cash or a check to the order of the Company in an amount equal to the
purchase price of such shares; (ii) subject to the consent of the Company, by
delivery to the Company of shares of Common Stock of the Company then owned by
the Optionee having a fair market value equal in amount to the purchase price of
such shares in accordance with Section 2(b); (iii) by any other means approved
by the Board of Directors and which is consistent with applicable laws and
regulations (including, without limitation, the provisions of Rule 16b-3 under
the Securities Exchange Act of 1934 and Regulation T promulgated by the Federal
Reserve Board); or (iv) by any combination of such methods of payment.

              (b)  METHOD OF PAYMENT -PUBLIC MARKET. In the event there exists a
public market for the Company's Common Stock on the date of exercise, payment of
the exercise price

                                        1
<PAGE>
may be made by surrender of shares of the Company's Common Stock. In this case
payment shall be made as follows:

                   (i)  Optionee shall deliver to the Secretary of the Company a
written notice which shall set forth the portion of the purchase price the
Optionee wishes to pay with Common Stock, and the number of shares of such
Common Stock the Optionee intends to surrender pursuant to exercise of this
Option, which shall be determined by dividing the aforementioned portion of the
purchase price by the average of the last reported bid and asked prices per
share of Common Stock of the Company, as reported in The Wall Street Journal,
(or, if not so reported, as otherwise reported by the National Association of
Securities Dealers Automated Quotation (NASDAQ) System or, in the event the
Common Stock is listed on a national securities exchange, or on the NASDAQ
National Market System, NASDAQ Small-Cap Market or any successor national market
system, the closing price of Common Stock of the Company on such exchange as
reported in the Wall Street Journal), for the day on which the notice of
exercise is sent or delivered;

                   (ii) Fractional shares shall be disregarded and the Optionee
shall pay in cash an amount equal to such fraction multiplied by the price
determined under subparagraph (i) above;

                   (iii)The written notice shall be accompanied by a duly
endorsed blank stock power with respect to the number of Shares set forth in the
notice, and the certificate(s) representing said Shares shall be delivered to
the Company at its principal offices within three (3) working days from the date
of the notice of exercise;

                   (iv) The Optionee hereby authorizes and directs the Secretary
of the Company to transfer so many of the Shares represented by such
certificate(s) as are necessary to pay the purchase price in accordance with the
provisions herein;

                   (v)  If any such transfer of Shares requires the consent of
the California Commissioner of Corporations or of some other agency under the
securities laws of any other state, or an opinion of counsel for the Company or
Optionee that such transfer may be effected under applicable Federal and state
securities laws, the time periods specified herein shall be extended for such
periods as the necessary request for consent to transfer is pending before said
Commissioner or other agency, or until counsel renders such an opinion, as the
case may be. All parties agree to cooperate in making such request for transfer,
or in obtaining such opinion of counsel, and no transfer shall be effected
without such consent or opinion if required by law; and

                   (vi) Nothwithstanding any other provision herein, the
Optionee shall only be permitted to pay the purchase price with shares of the
Company's Common Stock owned by him as of the exercise date in the manner and
within the time periods allowed under Rule 16b-3 promulgated under the
Securities Exchange Act of 1934 as such regulation is presently constituted, as
it is amended from time to time, and as it is interpreted now or hereafter by
the Securities and Exchange Commission and any such shares shall have been held
by the Optionee for not less than six (6) months.

                                        2
<PAGE>
         3.   EXERCISE OF OPTION. The Option shall vest and become exercisable
during its term, subject to the provisions of Section 5 below, as follows:

              (a)  VESTING AND RIGHT TO EXERCISE.

                   (i)  The Option hereby granted shall vest and become
exercisable as to the following schedule: a) 1/3 of the shares subject to this
Option, shall vest and become exercisable on the award date; b) 1/3 of the
shares subject to this Option, shall vest and become exercisable on the first
anniversary of the award date; c) 1/3 of the shares subject to this Option,
shall vest and become exercisable on the second anniversary of the award date.

If there should occur a "change of control" of the Company, as defined below,
then the Option shall immediately vest and become exercisable in full. For
purposes of the foregoing provision, a "change in control" means the occurrence
of any of the following:

                        (A)  any "person", as such term is used in Sections
13(d) and 14(d) of the Exchange Act of 1934, as amended (the "Exchange Act")
(other than the Company or its existing shareholders) is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly
or indirectly, of securities of the Company (or a successor to the Company)
representing 50% or more of the combined voting power of the then outstanding
securities of the Company or such successor;

                        (B)  the dissolution of the Company or liquidation of
more than 50% or more in value of the assets of the Company, (ii) any merger or
reorganization of the Company whether or not another entity is the survivor,
(iii) a transaction (other than the initial public offering of Company's shares)
pursuant to which holders, as a group, of all of the shares of the Company
outstanding before the transaction, hold, as a group, less than 50% of the
combined voting power of the Company or any successor company outstanding after
the transaction, or (iv) any other event or series of events which the board
determines, in its discretion, would materially alter the structure of the
Company or its ownership.

                   (ii) In the event of the Optionee's death, disability or
other termination of employment prior to exercise, the exercisability of the
Option shall be governed by Section 5, below.

                   (iii)The Option may be exercised in whole or in part but may
not be exercised as to fractional shares.

              (b)  METHOD OF EXERCISE. In order to exercise any portion of the
Option, the Optionee shall execute and deliver to the Chief Financial Officer of
the Company, the Notice of Exercise of Stock Option in the form attached hereto
as Exhibit A, together with the Consent of Spouse. The Notice of Exercise must
be accompanied by payment in full of the aggregate purchase price for the Shares
to be purchased in the type of consideration set forth in Section 2. The Notice
of Exercise may be delivered to the Company at any time. The certificate(s) for
the Shares as to which the Option has been exercised shall be registered in the
name of Optionee or his designee.

                                        3
<PAGE>
              (c)  RESTRICTIONS ON EXERCISE. The Option may not be exercised if
the issuance of the Shares upon such exercise or the method of payment of
consideration for such Shares would constitute a violation of any applicable
Federal or state securities law or any other law or regulation. As a condition
to the exercise of the Option, the Company may require the Optionee to make any
representation or warranty to the company at the time of exercise of the Option
as in the opinion of legal counsel for the Company may be required by any
applicable law or regulation, including the execution and delivery of an
appropriate representation statement. The stock certificate (s) for the Shares
issued upon exercise of the Option may bear appropriate legends restricting
transfer.

              (d)  DELIVERY OF CERTIFICATES. The Company shall deliver the
certificate(s) for the Shares issued upon exercise of the Option to the Optionee
as soon as is practicable; provided, however, that if any law or regulation
requires the Company to take any action with respect to such shares before the
issuance thereof, including, without limitation, actions taken pursuant to
Section 6 below, then the date of delivery of such Shares shall be extended for
a period necessary to take such action.

         4.   NON-TRANSFERABILITY OF OPTION. The Option may be exercised during
the lifetime of the Optionee only by the Optionee any may not be transferred in
any manner other than by will or by the laws of descent and distribution. The
terms of the Option shall be binding upon the executors, administrators, heirs
and successors of the Optionee.

         5.   TERM OF THE OPTION. Except as otherwise provided in this
Agreement, to the extent not previously exercised, the right to exercise the
Option shall terminate on the tenth (10th) anniversary of the Date of Grant.
Notwithstanding the foregoing, if an Optionee ceases to be an employee of the
Company he/she will be treated in the following manner relative to their option
exercise period: a) If the Optionee retires, their option exercise period will
be extended for three years from the date of retirement. b) If the Optionee dies
or becomes disabled, their option period will be extended for three years from
the date of such death or disability. In the event of death of Optionee, the
surviving heirs will have the same extended exercise right as that of the
Optionee. c) If the Optionee's employment is terminated for the benefit of the
Company, their option exercise period will be extended for three years from the
date of termination. d) In all other cases of separation, the option exercise
period will be 90 days; provided, however, that in no event may the Option be
exercised after its ten (10) year term has expired. To the extent that the
Optionee was not entitled to exercise an Option at the date of such termination,
or if he or she does not exercise such Option (which he or she was entitled to
exercise) within the time specified herein, the Option shall terminate.

         6.   ADJUSTMENTS UPON CHANGES IN CAPITALIZATION: OTHER ADJUSTMENTS.
Subject to any required action by the shareholders of the Company, the number of
Shares and the Exercise Price shall be proportionately adjusted for any increase
or decrease in the number of issued shares of common stock resulting from a
stock split, reverse stock split, combination, reclassification, the payment of
a stock dividend on the common stock or any other increase or decrease in the
number of shares of Common Stock of the Company effected without the receipt of
consideration by the Company; PROVIDED, HOWEVER, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the Board,
whose determination in that respect shall be final,

                                        4
<PAGE>
binding and conclusive. Except as expressly provided herein, no issue by the
Company of shares of stock of any class, or securities convertible into shares
of stock of any class, shall affect, and not adjustment by reason thereof shall
be made with respect to, the number of Shares subject to, or the Exercise Price
of, this Option.

The Board may, if it so determines in the exercise of its sole discretion, also
make provision for adjusting the number of Shares, we well as the Exercise
Price, in the event that the Company effects one or more reorganizations,
recapitalizations, rights offerings, or other increases or reductions of shares
of its outstanding common stock, and in the event of the Company being
consolidated with or merged into any other corporation; provided, however, that
in no event shall the Optionee be adversely affected by such adjustment.

The Board may, if it so determines in the exercise of its sole discretion, also
make provision for changing, modifying, amending or adjusting any of the terms
of this Option solely in order for the Company to perfect a significant
financing; provided, however, that in no event shall the Optionee be adversely
affected by such adjustment.

         7.   RIGHTS OF SHAREHOLDER. Optionee shall have no rights as a
shareholder with respect to the Shares until the date of the issuance or the
transfer to the Optionee of the certificate(s) for such Shares and only after
the Exercise Price for such Shares has been paid in full.

         8.   AMENDMENT. Except as set forth in Section 6, this Agreement may
not be amended without the written consent of the Optionee.

         9.   INCOME TAX WITHHOLDING. The Optionee authorizes the Company to
withhold, in accordance with applicable law from any compensation payable to him
or her, any taxes required to be withheld by Federal, state or local laws as a
result of the exercise of this Option. Furthermore, in the event of any
determination that the Company has failed to withhold a sum sufficient to pay
all withholding taxes due in connection with the exercise of this Option, the
Optionee agrees to pay the Company the amount of such deficiency in cash within
five (5) days after receiving a written demand from the Company to do so,
whether or not Optionee is an employee or director of the Company at that time.

         10.  INVESTMENT REPRESENTATIONS; LEGENDS.

              (a)  REPRESENTATIONS. The Optionee represents, warrants and
covenants that:

                   (i)  Any shares purchased upon exercise of this Option shall
be acquired for the Optionee's account for investment only, and not with a view
to, or for sale in connection with, any distribution of the shares in violation
