2. PRIME LEASE. Landlord is the tenant under a Lease Agreement and certain
amendments thereto (collectively, the "Prime Lease") identified in Section 1(F)
with the Prime Landlord identified in Section 1(D). The Prime Lease is attached
hereto as Exhibit "B". Landlord represents and warrants to Tenant that (a)
Landlord has delivered to Tenant a full and complete copy of the Prime Lease and
all other agreements between Prime Landlord and Landlord relating to the
leasing, use, and occupancy of the Premises, (b) the Prime Lease is, as of the
date hereof, in full force and effect, and (c) no event of default has occurred
under the Prime Lease and, to Landlord's knowledge, no event has occurred and is
continuing which would constitute an event of default but for the requirement of
the giving of notice and/or the expiration of the period of time to cure. Except
as expressly set forth in this Sublease, Tenant hereby agrees to be bound by all
of the terms, conditions and covenants of the Prime Lease and, for purposes of
this Sublease, the term "Landlord" in the Prime Lease shall be deemed to refer
to the Landlord under this Sublease and the term "Tenant" in the Prime Lease
shall be deemed to refer to "Tenant" under this Sublease.

3. SUBLEASE. In consideration of the rents herein reserved and of the covenants
and agreements herein contained on the part of the Tenant to be performed,
Landlord hereby subleases to the Tenant, and the Tenant accepts from the
Landlord, certain space described in Section 1(B) (the "Premises") and located
in the building, situated on and a part of the property (the "Property") more
particularly described in the Prime Lease.

4. TERM. The term of this Sublease (hereinafter "Term") shall commence on the
date hereof. The Term shall expire on the date ("Expiration Date") specified in
Section 1(I), unless sooner terminated as otherwise provided elsewhere in this
Sublease.

5. POSSESSION. Landlord agrees to deliver possession of the Premises on or
before the Commencement Date in their condition as of the execution and delivery
hereof, reasonable wear and tear excepted; that is to say, AS IS.

6. TENANT'S IMPROVEMENTS. Tenant agrees to lease from Landlord all leasehold
improvements, furniture, fixtures and equipment listed on Exhibit "C" attached
hereto for One Dollar ($1.00) per year beginning on the Commencement Date and
ending on the Expiration Date. Tenant acknowledges that the leasehold
improvements, furniture, fixtures and equipment are in good working order and
that all maintenance and repair costs to maintain the good and working order of
such leasehold improvements, furniture, fixtures and equipment are the
responsibility of Tenant.

7. RENT. Beginning on the Commencement Date, Tenant agrees to pay the Base Rent
set forth in Section I(J) to the Landlord, at the address specified in Section
1(C), or to such other payee or at such other address as may be designated by
notice in writing from Landlord to Tenant, without prior demand therefor and
without any deduction whatsoever. Base Rent shall be paid in equal monthly
installments in advance on the first day of each month of the Term, except that
the first installment of Base Rent shall be paid by Tenant to Landlord upon
execution of this Sublease by Tenant. Base Rent shall be pro-rated for partial
months at the beginning and end of the

                                       2
<PAGE>

Term. All charges, costs and sums required to be paid by Tenant to Landlord
under this Sublease in addition to Base Rent shall be deemed "Additional Rent,"
and Base Rent and Additional Rent shall hereinafter collectively be referred to
as "Rent." Tenant's covenant to pay Rent shall be independent of every other
covenant in this Lease. If Rent is not paid when due, Tenant shall pay, relative
to the delinquent payment, an amount equal to the sum which would be payable by
Landlord to Prime Landlord for an equivalent default under the Prime Lease.

8.       ADDITIONAL RENT.

         A.       If and to the extent that Landlord is obligated to pay
                  additional rent under the Prime Lease, whether such additional
                  rent is to reimburse Prime Landlord for taxes, operating
                  expenses, common area maintenance charges or other expenses
                  incurred by the Prime Landlord in connection with the
                  Property, Tenant shall pay to Landlord the percentage of such
                  additional rent (to the extent such additional rent is
                  attributable to events occurring during the term of this
                  Sublease) which is set forth in Section 1(K) as the Sublease
                  Share. Such payment shall be due from Tenant to Landlord no
                  fewer than five (5) days prior to the date upon which
                  Landlord's payment of such additional rent is due to the Prime
                  Landlord, provided that Tenant shall have been billed therefor
                  at least ten (10) days prior to such due date (which bill
                  shall be accompanied by a copy of Prime Landlord's bill and
                  other material furnished to Landlord in connection therewith).

         B.       The Sublease Share provided for in Section 1(K) is calculated
                  by dividing the rentable area of the Premises by the rentable
                  area of the premises leased by Prime Landlord to Landlord
                  pursuant to the Prime Lease. In the event the rentable area of
                  the Premises or the area of the premises leased pursuant to
                  the Prime Lease shall be changed during the Term, then the
                  Sublease Share shall be recalculated.

         C.       To the extent not covered by Section 8(A) above, Tenant shall
                  obtain and maintain in full force and effect throughout the
                  Term insurance coverage for the leasehold improvements and
                  equipment in the Premises in such amounts and with such
                  carriers as reasonably approved by Landlord. In addition,
                  Tenant also shall pay its share of property taxes and
                  utilities (including alarm system).

9.       PRIME LANDLORD'S CONSENT. This Sublease and the obligations of the
parties hereunder are expressly conditioned upon Landlord's obtaining prior
written consent hereto by Prime Landlord and Prime Landlord waiving any rights
it may have to recapture the Premises or any Base Rent or Additional Rent
payable by Tenant to Landlord pursuant to the terms of the Prime Lease.

10.      BROKERAGE. Each party warrants to the other that it has had no dealings
with any broker or agent in connection with this Sublease, and covenants to pay,
hold harmless

                                       3
<PAGE>

and indemnify the other party from and against any and all costs (including
reasonable attorneys' fees), expense or liability for any compensation,
commission and charges claimed by any broker or agent with respect to this
Sublease or the negotiation thereof on behalf of such party.

11.      FORCE MAJEURE. Landlord shall not be deemed in default with respect to
any of the terms, covenants and conditions of this Sublease on Landlord's part
to be performed if Landlord's failure to timely perform same is due in whole or
in part to any strike, lockout, labor trouble (whether legal or illegal), civil
disorder, failure of power, restrictive governmental laws and regulations,
riots, insurrections, war, shortages, accidents, casualties, acts of God, acts
caused directly by Tenant or Tenant's agents, employees and invitees, or any
other cause beyond that reasonable control of Landlord. This Section shall not
be applicable, however, if Landlord's failure timely to perform creates a
default by Landlord under the Prime Lease.

12.      SUCCESSORS AND ASSIGNS. This Sublease shall be binding upon and
enforceable by, and shall inure to the benefit of, the parties hereto and their
respective successors and assigns.

13.      ATTORNEYS' FEES. In the event of the bringing of any action by any
party hereto against any other party arising out of this Sublease, the party who
is determined to be the prevailing party shall be entitled to recover from the
other party all costs and expenses of suit, including reasonable attorneys'
fees.

14.      COUNTERPARTS. This Sublease may be executed in counterparts, each of
which shall be deemed an original, but all of which, together, shall constitute
one and the same instrument.

                         SETTLEMENT AND GENERAL RELEASE

         This Settlement and General Release ("SETTLEMENT AGREEMENT") is
effective as of June 30, 2000, by and among Ike E. Lynch, Daniel L. McPeak, Jr.,
and Todd C. Crow (each, an "OPTIONEE" and collectively, the "OPTIONEES") and The
RiceX Company, a Delaware corporation (the "COMPANY").

         A. On November 1, 1999, the Company and each Optionee entered into a
Nonstatutory Stock Option Agreement (each, a "STOCK OPTION AGREEMENT" and
collectively, the "STOCK OPTION AGREEMENTS"), whereby the Company granted to
each of the Optionees stock options (the "OPTIONS") under the Company's 1997
Stock Option Plan (the "PLAN") to acquire 900,000 shares of Company common stock
at a price of seventy-two cents ($0.72) per share. The Optionees each
immediately exercised Options for 500,000 shares and tendered promissory notes
to the Company secured by the shares in payment of the exercise price. On May 1,
2000, the Optionees each exercised Options for the remaining 400,000 shares
(together with the 1999 shares, the "OPTION SHARES") in exchange for the
promissory notes (together with the 1999 promissory notes, the "NOTES").

         B. The parties now dispute whether the exercise of the Options in
exchange for the Notes was in the best interests of the Company and wish to
mutually rescind the exercise of the Options and restore the parties to their
respective positions prior to the exercise.

         Through this Settlement Agreement, the parties now wish to settle and
finally resolve all disputes between them including, but not limited to, all
issues relating to the grant and/or exercise of the Options and the tendering of
the Notes. In consideration of the mutual covenants and agreements contained
herein, and subject to the terms and conditions set forth herein, the parties
agree as follows:

                                    SECTION 1
                                MUTUAL RESCISSION

         1.1 RESCISSION OF THE EXERCISE OF THE STOCK OPTIONS. The parties hereby
agree to rescind each exercise of the Stock Options on November 1, 1999 and May
1, 2000. Accordingly, the exercise of the Options is ineffective and any Notice
of Exercise delivered pursuant to section 3(b) of the Stock Option Agreement is
similarly rescinded. The Optionees agree to return all Option Shares, along with
executed stock powers, to the Company for cancellation.

         1.2 RESCISSION OF NOTES. The parties hereby rescind each of the Notes
dates as of November 1, 1999 and May 1, 2000 between the Company and each
Optionee tendered as consideration for the exercise price of the Options.
Accordingly, all interest paid under each of the Notes shall be returned to the
respective Optionee, and all accrued and unpaid interest shall

<PAGE>

be cancelled. The parties mutually agree to forego all rights and benefits
provided for under the Notes.

         1.3 RESTORATION OF THE PARTIES. The mutual rescissions and all other
actions taken pursuant to sections 1.1 and 1.2 above shall be effective as of
November 1, 1999 and May 1, 2000, as applicable, and shall fully extinguish the
Notes and the exercise of the Stock Options as if never formed so as to restore
the parties to the positions they occupied prior to the exercise of the Options.
Accordingly, the Stock Option Agreements are fully executory, exactly as they
were upon grant and prior to exercise, and all 900,000 shares are available for
future exercise according to the terms of the Stock Option Agreements.

                                    SECTION 2
                                    RELEASES

(including any of said persons or entities) by reason of any occurrence, damage
or injury whatsoever sustained at any time prior to and including the date this
Settlement Agreement is executed by all parties, related to the grant and/or
exercise of the Options, the rescission of the exercise of the Options, and the

Agreement is executed by all parties related to the grant and/or exercise of the

         SETTLEMENT WITH THE DEBTOR.
