Item 5.       Other Events

    On January 26, 1996, Empresas La Moderna S.A. de C.V. ("ELM") and
certain of its affiliates and DNA Plant Technology Corporation ("DNAP") signed
a definitive merger agreement to combine ELM's fresh produce subsidiary,
Bionova S.A. de C.V. ("Bionova"), with DNAP.  Under the terms of the agreement
and plan of merger (the "Merger Agreement"),  Bionova will transfer its
controlling interest in its subsidiaries to a new holding company, Bionova
U.S., Inc., a newly formed Delaware corporation to be renamed "DNAP Holding
Corporation" ("Holding").  In the merger (the "Merger"), DNAP will merge with
a merger subsidiary of Holding (with DNAP as the surviving entity).  As a
result of the transactions contemplated by the Merger Agreement,  ELM or an
affiliate will receive a 70% interest in Holding, and DNAP common and
preferred stockholders, in the aggregate, will receive 30% of the common stock
of Holding (which is expected to trade on the Nasdaq NMS), assuming no
exercise of dissenters' rights.

    Under the Merger Agreement, at the effective time of the Merger DNAP's
common stockholders will receive one share of Holding common stock for each
share of DNAP common stock; holders of DNAP $2.25 Convertible Exchangeable
Preferred Stock will receive 6.8375 shares of Holding common stock for each of
their preferred shares; and holders of DNAP Series A Convertible Preferred
Stock will receive 1,000 shares of Holding common stock for each of their
preferred shares.  Options and warrants of DNAP will become options and
warrants to acquire Holding common stock on essentially the same terms.

    Under the Merger Agreement, ELM has agreed to guarantee certain loans to
Holding with a maximum exposure of $20 million.  ELM (directly or through its
related companies, including Asgrow Seed Company, Petoseed and Royal Sluis),
has agreed to enter into a Long-Term Funded Research Agreement with Holding
upon the closing of the Merger, committing ELM or its subsidiaries to fund $30
million in future research and development at Holding over a ten-year period. 
The research commitment involves minimum quarterly payments to Holding of
$625,000 and minimum payments of $9 million over each three-year period.

    Holding and DNAP have also entered into a three-year Loan Agreement
whereby DNAP will borrow $10 million ($5 million funded upon the execution of
the Merger Agreement and $5 million to be funded on July 1, 1996).  As
provided in the Merger Agreement, funding for such loan has been or will be
provided to Holding by ELM or affiliates thereof.  The Merger Agreement also
provides that the $10 million in funding provided to Holding by ELM or
affiliates thereof will be deemed a contribution to the capital of Holding as
of the effective time of the Merger.  As security for the loan, DNAP has
assigned to Holding, while the loan is outstanding, certain patents and patent
applications, including those relating to DNAP's Transwitch technology, but
will retain certain rights to use the patents.  Under a Non-Exclusive Patent
License entered into with Holding, DNAP will receive, in exchange for a non-
exclusive license of the Transwitch patents to Holding, certain license fees
and product royalties. 

    The closing of the Merger is subject to approval by holders of a
majority of the outstanding common stock of DNAP as well as other conditions.

    After the Merger, Robert Serenbetz, the present chief executive officer
of DNAP, and three independent directors from the present DNAP Board will be
included on the Holding Board of Directors, which is also expected to include
initially an additional seven (7) directors (including one independent
director) appointed by ELM.  Pursuant to a Governance Agreement, to be entered
into at the effective time of the Merger, approval of a majority of a
committee of independent directors will be required until Holding's 1999
annual stockholder's meeting for certain transactions, including, among other
things, certain material transactions between Holding and ELM or its
affiliates.  In addition, the Governance Agreement contains certain
limitations on the ability of ELM and its affiliates to buy or sell shares of
Holding stock for three years after the closing of the Merger. 

    Under the terms of the Merger Agreement, the DNAP Board and its advisors
are available to receive inquiries from other parties interested in the
possible acquisition of or merger with DNAP and, as appropriate, to provide
information and enter into discussions and negotiations with such parties in
connection with such indicated interest.  Under the Merger Agreement, DNAP may
ultimately enter into an agreement with such third party.  If the Merger is
not consummated, certain fees and expenses may become payable by Holding to
DNAP or by DNAP to Holding on the terms provided in the Merger Agreement.

                    THE MERGER AND RELATED TRANSACTIONS

     1.1  The Merger.  At the Effective Time, and on the terms and subject
to the conditions set forth in this Agreement, Sub shall be merged with and
into the Company (the "Merger"), the Company shall continue its corporate

will cause the Merger to be consummated by filing with the Secretary of State
of Delaware a certificate of merger in such form as required by, and executed
in accordance with, the relevant provisions of State Law.  The Merger shall
become effective at such time as the certificate of merger is duly filed with
the Secretary of State of Delaware (the "Effective Time").

     1.3  Closing.  The closing of the Merger (the "Closing") shall take
place (i) at the offices of Thompson & Knight, 1700 Pacific Avenue, Suite
3300, Dallas, Texas 75201, as soon as practicable after the satisfaction or,
if permissible, waiver of the conditions to the obligations of the parties set
forth in Articles VIII, IX and X or (ii) at such other time or place or on
such other date as the parties hereto shall agree, provided that the closing
conditions set forth in Articles VIII, IX and X have been satisfied or waived
at or prior to such other time and date.  The date on which the Closing occurs
is herein referred to as the "Closing Date".  All Closing transactions shall
be deemed to have occurred simultaneously.

     1.4  Effects of the Merger.  The Merger shall have the effects set
forth in the applicable provisions of State Law.  Without limiting the
generality of the foregoing, and subject thereto, at the Effective Time, all
the properties, rights, privileges, powers, and franchises of the Company and

assignment having occurred, and all debts, liabilities, and duties of the
Company and Sub shall become the debts, liabilities, and duties of the
Surviving Corporation.

     1.5  Certificate of Incorporation.  The Certificate of Incorporation of
the Company, as in effect immediately prior to the Effective Time, shall be
the Certificate of Incorporation of the Surviving Corporation, until
thereafter amended in accordance with its terms and as provided by State Law.

     1.6  Bylaws.  The Bylaws of the Company, as in effect immediately prior
to the Effective Time, shall be the Bylaws of the Surviving Corporation, until
thereafter amended in accordance with its terms and as provided by State Law.

Effective Time shall be as set forth in Schedule 1.7, each to hold office in
accordance with the Certificate of Incorporation and Bylaws of Bionova U.S.
and until his successor is duly elected and qualified in accordance with State
Law or until his earlier death, resignation, or removal.  Not later than the
date on which the Company first transmits its preliminary Proxy Statement to
the Securities and Exchange Commission as provided in Section 7.4, letters
from each of those persons identified in Schedule 1.7 shall have been obtained
pursuant to which they shall consent to their designation as such directors;
provided that if any such person shall not have consented to serve as a

Effective Time shall be identified by Bionova U.S. not later than the date on
which the Company first transmits its preliminary Proxy Statement to the

and Bylaws of Bionova U.S. and until his successor is duly elected and
qualified in accordance with State Law or until his earlier death,
resignation, or removal.

     1.9  Name Change.  Prior to or on the Closing Date, the Certificate of
Incorporation of Bionova U.S. shall be amended to change the name of Bionova
U.S. to "DNAP Holding Corporation."

     1.10 Directors of the Surviving Corporation.  Prior to or on the
Closing Date, the then existing directors of the Company and each Company
Subsidiary shall have submitted their resignations from such positions.  On
the Closing Date, Bionova U.S., then acting as the sole stockholder of the
Surviving Corporation, and the Surviving Corporation, then acting as the sole

of each of the Surviving Corporation and each Company Subsidiary, as the case
may be, the persons listed on Schedule 1.10.  Such persons shall hold office
in accordance with the Certificate of Incorporation and Bylaws of the
Surviving Corporation and each Company Subsidiary, as the case may be, and
until his successor is duly elected and qualified in accordance with State Law
or until his earlier death, resignation, or removal.  Not later than the date
on which the Company first transmits its preliminary Proxy Statement to the
Securities and Exchange Commission as provided in Section 7.4, letters from
each of those persons identified in Schedule 1.10 shall have been obtained
pursuant to which they shall consent to their designation as such directors;
provided that if any such person shall not have consented to serve as a
director by that date, then a substitute therefor shall be appointed by
Parent.

     1.11 Capitalization of Bionova U.S. and Surviving Corporation.

          (a)  Concurrent with the execution and delivery of this
     Agreement, Bionova U.S. and the Company have entered into the Loan
     Agreement and Bionova U.S. has loaned the sum of $5 million to the
     Company as provided in Section 2.01(i) of the Loan Agreement.  Subject
     to the terms of the Loan Agreement, on the date specified in Section
     2.01(ii) of the Loan Agreement, Bionova U.S. shall, and Parent shall
     cause Bionova U.S. to, loan the additional sum of $5 million to the
     Company as provided therein. In each such case, Parent or affiliates
     thereof will have provided such funds to Bionova U.S. and such funds
     will have been provided to Bionova U.S. from sources other than the
     members of the Bionova Group.

          (b)  On the Closing Date, Parent shall cause to be transferred to
     Bionova U.S. free and clear of all Encumbrances all of the capital stock
     then owned by Parent or affiliates thereof in IPHC and ABSA, which
     entities shall then own, directly or indirectly, all of the issued and
     outstanding capital stock of each other member of the Bionova Group
     (except for Bionova Mexico, except to the extent specified in Schedule
     5.4 and except for dormant members of the Bionova Group which do not
     have material operations or assets).  At such time, such transferred
     businesses shall represent all of the assets and earning power indicated
     in the Bionova Group Financial Statements delivered pursuant to Section
     5.5 (except for immaterial variations resulting from the ordinary course
     of business).

          (c)  On the Closing Date, Parent shall cause the $10 million
     provided to Bionova U.S. referenced in Section 1.11(a) to be deemed a
     contribution to the capital of Bionova U.S.  Under such circumstances,
     any related accounting entries previously recorded by any of Parent or
     its affiliates or by Bionova U.S., as the case may be, shall be
     appropriately modified to reflect such capital contribution, and any
     conflicting written arrangements shall be deemed cancelled and of no
     further force and effect.

          (d)  In consideration of the transactions specified in Section
     1.11(b) and Section 1.11(c), on the Closing Date Bionova U.S. shall
     issue to Bionova Mexico such number of shares of Bionova U.S. Common
     Stock as shall represent (when added to the 25,000 shares of Bionova
     U.S. Common Stock owned by Bionova Mexico as of the date of this
     Agreement) 70% (assuming that the holder of any Dissenting Shares does
     not exercise its appraisal rights under State Law) of the issued and
     outstanding shares thereof as of the Effective Time of the Merger.  Such
     shares shall be fully paid and nonassessable shares of Bionova U.S.
     Common Stock.  At the Effective Time, all other issued and outstanding
     shares of Bionova U.S. Common Stock shall be represented by the shares
     thereof issued pursuant to Sections 2.1(a), (b) and (c).


                                ARTICLE II

       CONVERSION OF SECURITIES; ASSUMPTION OF OPTIONS AND WARRANTS

     2.1  Conversion of Securities.  At the Effective Time, by virtue of the
Merger and without any action on the part of Parent, Bionova U.S., Sub, the
Company or any holder of any of the following securities, the following events
will transpire:

          (a)  Each then outstanding share of Common Stock, par value $0.01
     per share, of the Company ("Company Common Stock") (other than the
     shares of Company Common Stock referred to in Section 2.1(d)) shall be
     converted into the right to receive one fully paid and nonassessable
     share of Common Stock, par value $0.01 per share, of Bionova U.S.
     ("Bionova U.S. Common Stock"), provided, however, that no fractional
     shares of Bionova U.S. Common Stock shall be issued, and, in lieu
     thereof, a cash payment shall be made in accordance with Section 2.3(d). 
     All such shares, when so converted, shall no longer be outstanding and
     shall automatically be cancelled and retired and shall cease to exist,
     and each holder of a certificate representing any such shares shall
     cease to have any rights with respect thereto, except the right to
     receive shares of Bionova U.S. Common Stock and any cash in lieu of
     fractional shares as hereinafter provided.

          (b)  Each then outstanding share of $2.25 Convertible
     Exchangeable Preferred Stock, par value $0.01 per share, of the Company
     ("Company Convertible Exchangeable Preferred Stock") (other than the
     shares of such stock referred to in Section 2.1(d)) shall be converted
     into the right to receive 6.8375 fully paid and nonassessable shares of
     Bionova U.S. Common Stock, provided, however, that no fractional shares
     of Bionova U.S. Common Stock shall be issued, and, in lieu thereof, a
     cash payment shall be made in accordance with Section 2.3(d).  All such
     shares, when so converted, shall no longer be outstanding and shall
     automatically be cancelled and retired and shall cease to exist, and
     each holder of a certificate representing any such shares shall cease to
     have any rights with respect thereto, except the right to receive shares
     of Bionova U.S. Common Stock and any cash in lieu of fractional shares
     as hereinafter provided.

          (c)  Each then outstanding share of Series A Convertible
     Preferred Stock, par value $0.01 per share, of the Company ("Company
     Series A Preferred Stock") (other than (i) the shares of such stock
     referred to in Section 2.1(d) and (ii) Dissenting Shares) shall be
     converted into the right to receive 1,000 fully paid and non assessable
     shares of Bionova U.S. Common Stock, provided, however, that no
     fractional shares of Bionova U.S. Common Stock shall be issued, and, in
     lieu thereof, a cash payment shall be made in accordance with Section
     2.3(d).  All such shares, when so converted, shall no longer be
     outstanding and shall automatically be cancelled and retired and shall
     cease to exist, and each holder of a certificate representing any such
     shares shall cease to have any rights with respect thereto, except the
     right to receive shares of Bionova U.S. Common Stock and any cash in
     lieu of fractional shares or any amount paid in respect to appraisal
     rights, if any, as hereinafter provided.

          (d)  Each share of Company Common Stock, Company Convertible
     Exchangeable Preferred Stock and Company Series A Preferred Stock
     (collectively "Company Stock") then held in the treasury of the Company
     or by any of the Company Subsidiaries shall be cancelled and
     extinguished without any conversion thereof and no payment shall be made
     with respect thereto.

          (e)  Each then outstanding share of Common Stock, par value $.01
     per share, of Sub shall be converted into and become one fully paid and
     nonassessable share of Company Common Stock.

          (f)  All then outstanding options and warrants to purchase
     Company Common Stock will be assumed by Bionova U.S. in accordance with
     Sections 2.5 and 2.6.

     The consideration to be paid or delivered to each holder of Company
Stock pursuant to any of Sections 2.1(a), (b) and (c) is herein referred to as
the "Merger Consideration."

     2.2  Dissenting Shares.  Notwithstanding anything in this Agreement to
the contrary, if the holder of shares of Company Series A Preferred Stock has
demanded appraisal of such shares in accordance with State Law, and if State
Law provides for appraisal rights for such shares in the Merger ("Dissenting
Shares"), then such holder shall be entitled to appraisal rights for his
Dissenting Shares in accordance with the provisions of State Law; provided
that such holder properly perfects his right to appraisal of his Dissenting
Shares under State Law.  The Company shall give Bionova U.S. prompt notice of
any demands received by the Company for appraisal of shares, and Bionova U.S.
shall have the right to participate in all negotiations and proceedings with
respect to such demands.  The Company shall not, except with the prior written
consent of Bionova U.S., make or agree to make any payment with respect to, or
settle or offer to settle, any such demands.

     2.3  Exchange of Certificates.

          (a)  Pursuant to an agreement, to be entered into on or before
     the Closing Date among Bionova U.S., the Company, and such designee,
     Bionova U.S. shall designate a bank or trust company reasonably
     acceptable to the Company to act as exchange agent in the Merger (the
     "Exchange Agent") for purposes of effecting the exchange for the Merger
     Consideration of certificates that, immediately prior to the Effective
     Time, represented shares of Company Stock entitled to receive the Merger
     Consideration pursuant to Section 2.1 ("Certificates").  Upon the
     surrender to the Exchange Agent of each Certificate, together with the
     letter of transmittal contemplated by Section 2.3(f) duly completed and
     executed, the Exchange Agent shall pay the holder of such Certificate
     the applicable Merger Consideration in exchange therefor, and such
     Certificate shall forthwith be cancelled.  Until so surrendered and
     exchanged, each such Certificate shall represent solely the right to
     receive the applicable Merger Consideration and any amounts to which the
     holder thereof is entitled pursuant to Sections 2.3(c) and (d).  No
     interest shall be paid or accrue on the Merger Consideration.  If the
     Merger Consideration (or any portion thereof) is to be delivered to any
     person other than the person in whose name the Certificate surrendered
     in exchange therefor is registered, it shall be a condition to such
     exchange that (i) the Certificate so surrendered shall be properly
     endorsed or otherwise be in proper form for transfer and (ii) the person
     requesting such exchange shall pay to the Exchange Agent any transfer or
     other Taxes required by reason of the payment of the Merger
     Consideration to a person other than the registered holder of the
     Certificate surrendered or establish to the satisfaction of the Exchange
     Agent that such Tax has been paid or is not applicable.  Bionova U.S.
     may impose such other reasonable conditions upon the exchange of
     Certificates as it may deem necessary or desirable and as are consistent
     with the provisions of this Agreement.  Bionova U.S. Common Stock into
     which Company Stock shall be converted pursuant to this Agreement and
     the Merger shall be deemed to have been issued at the Effective Time;
     provided, however, that, subject to Applicable Law, no holder of an
     unsurrendered Certificate shall be entitled, until the surrender of such
     Certificate, to vote the shares of Bionova U.S. Common Stock into which
     his or her Company Stock shall have been converted.

          (b)  At or immediately prior to the Effective Time, Bionova U.S.
     shall deposit, or cause to be deposited, in trust with the Exchange
     Agent stock certificates representing the aggregate stock Merger
     Consideration to which holders of shares of Company Stock shall be
     entitled at the Effective Time pursuant to Section 2.1 (the "Payment
     Fund").  The Exchange Agent shall, pursuant to irrevocable instructions,
     make the payments or deliveries referred to in Section 2.3(a) out of the
     Payment Fund.  The Payment Fund shall not be used for any other purpose
     except as expressly provided in this Agreement.

          (c)  Unless and until a Certificate is surrendered, dividends
     payable to the holders of record of Bionova U.S. Common Stock shall not
     be paid to the holder of such Certificate in respect of the Bionova U.S.
     Common Stock represented thereby, but, subject to applicable abandoned
     property, escheat, and similar laws, there shall be paid to the holder
     thereof (i) upon surrender of such Certificate, the amount of any
     dividends, the record date for the determination of the holders entitled
     to which shall be after the Effective Time, which theretofore shall have
     become payable with respect to the whole shares of Bionova U.S. Common
     Stock represented by such Certificate and issued in exchange upon its
     surrender, but without interest on such dividends, and (ii) after
     surrender of such Certificate, the amount of any dividends with respect
     to such whole shares of Bionova U.S. Common Stock, the record date for
     the determination of the holders entitled to which shall be after the
     Effective Time but prior to the surrender of such Certificate, and the
     payment date of which shall be subsequent to such surrender, such amount
     to be paid on such payment date.

          (d)  No certificates or scrip representing fractional shares of
     Bionova U.S. Common Stock shall be issued upon the surrender for
     exchange of any Certificate.  In lieu of any such fractional share of
     Bionova U.S. Common Stock, each holder of a Certificate whose aggregate
     number of shares of Company Stock are not convertible into a whole
     number of shares of Bionova U.S. Common Stock shall be entitled to
     receive from the Exchange Agent, upon surrender of such holder's
     Certificates for exchange as provided above, an amount of cash rounded
     to the nearest cent (without interest) determined by multiplying such
     fractional interest by the mean closing sales price of Bionova U.S.
     Common Stock as reported on NASDAQ National Market System ("NASDAQ NMS")
     for the ten trading days immediately following the fifth trading day
     after the Closing Date.  After the Closing Date, Bionova U.S. shall
     deposit with the Exchange Agent, as and when required, cash sufficient
     for the Exchange Agent to make payment of cash in lieu of fractional
     shares in accordance with this Section 2.3(d).  Notwithstanding the
     foregoing, further rules and regulations concerning the settlement of
     fractional shares otherwise issuable, not inconsistent with this
     Agreement, may be adopted by Bionova U.S.

          (e)  Promptly following the date which is one year after the
     Effective Time, the Exchange Agent shall deliver to Bionova U.S. all
     cash, certificates, and other documents and instruments in its
     possession relating to the transactions described in this Agreement, and
     the Exchange Agent's duties shall terminate.  Thereafter, each holder of
     a Certificate may surrender such Certificate to Bionova U.S. and
     (subject to applicable abandoned property, escheat, and similar laws)
     receive in exchange therefor the applicable Merger Consideration and any
     amounts to which such holder is entitled pursuant to Sections 2.3(c) and
     (d), but such holder shall have no greater rights against Bionova U.S.
     than may be accorded to general creditors of Bionova U.S. under
     Applicable Law.  Notwithstanding anything in this Agreement to the
     contrary, neither the Exchange Agent nor any party hereto shall be
     liable to a holder of shares of Company Stock for any cash or other
     property delivered to a public official pursuant to applicable abandoned
     property, escheat, or similar laws.

          (f)  Promptly after the Effective Time, the Exchange Agent shall
     mail to each record holder of a Certificate a form of letter of
     transmittal (which shall specify that delivery of a Certificate shall be
     effected, and risk of loss and title to a Certificate shall pass, only
     upon proper delivery of the Certificate to the Exchange Agent and shall
     be in such form and contain such other provisions, reasonably acceptable
     to the Company, as Bionova U.S. shall specify) and instructions for use
     in surrendering such Certificate and receiving the applicable Merger
     Consideration in exchange therefor.

          (g)  At the Effective Time, the stock transfer books of the
     Company shall be closed and no transfers of Company Stock shall
     thereafter be made.  If, after the Effective Time, Certificates are
     presented to the Surviving Corporation or the Exchange Agent, they shall
     be cancelled and exchanged for the applicable Merger Consideration as
     provided in Section 2.1, subject to State Law in the case of Dissenting
     Shares.

          (h)  In the event any Certificate shall have been lost, stolen,
     or destroyed, upon the making of an affidavit of that fact by the person
     claiming such Certificate to be lost, stolen, or destroyed, Bionova U.S.
     shall issue or cause to be issued in exchange for such lost, stolen, or
     destroyed Certificate the Merger Consideration deliverable in respect
     thereof as determined in accordance with Section 2.1.  When authorizing
     such issue of the Merger Consideration in exchange therefor, Bionova
     U.S. may, in its discretion and as a condition precedent to the issuance
     thereof, require the owner of such lost, stolen, or destroyed
     Certificate to give Bionova U.S. a bond in such sum as it may direct as
     indemnity against any claim that may be made against Bionova U.S. with
     respect to the Certificate alleged to have been lost, stolen, or
     destroyed.

          (i)  Bionova U.S. shall be entitled to deduct and withhold from
     the Merger Consideration otherwise payable pursuant to this Agreement to
     any holder of a Certificate such amounts as Bionova U.S. is required to
     deduct and withhold with respect to the making of such payment under the
     Code or any provision of state, local, or foreign tax law.  To the
     extent that amounts are so withheld by Bionova U.S., such withheld
     amounts shall be treated for all purposes of this Agreement as having
     been paid to the holder of the Certificate in respect of which such
     deduction and withholding was made by Bionova U.S.

     2.4  Adjustment.  Subject to compliance with Section 6.2, in the event
of any stock split, combination, reclassification, recapitalization, exchange,
or stock dividend or distribution with respect to shares of Company Common
Stock or Bionova U.S. Common Stock (or if a record date with respect to any of
the foregoing should occur) during the period between the date of this
Agreement and the Effective Time, then the conversion rates set forth in
Section 2.1 shall be appropriately adjusted to reflect such stock split,
combination, reclassification, recapitalization, exchange, stock dividend, or
other distribution.

     2.5  Stock Options.

          (a)  At the Effective Time, each then outstanding option
     (including any option comprising a part of a unit) to purchase shares of
     Company Common Stock (a "Company Stock Option") shall become an option
     applicable to Bionova U.S., which Company Stock Option shall thereafter
     constitute an option to acquire on the same terms, conditions and
     vesting requirements as were applicable under the Company Stock Option,
     the same number of shares of Bionova U.S. Common Stock as the holder of
     such Company Stock Option would have been entitled to receive pursuant
     to the Merger had such holder exercised such option in full immediately
     prior to the Effective Time, at a price per share equal to (y) the
     aggregate exercise price for the shares of Company Common Stock
     otherwise purchasable pursuant to such Company Stock Option divided by
     (z) the number of full shares of Bionova U.S. Common Stock deemed
     purchasable pursuant to such option in accordance with the foregoing,
     and Bionova U.S. agrees to issue such Bionova U.S. Common Stock upon any
     such exercise; provided, however,  that in the case of any Company Stock
     Option to which Section 422 of the Code applies (incentive stock
     options), the option price, the number of shares purchasable pursuant to
     such option and the terms and conditions of exercise of such option
     shall be determined in order to comply with Section 424(a) of the Code. 
     As soon as practicable after the Effective Time, Bionova U.S. shall
     deliver to the participants in the Company's stock option plans
     appropriate notice setting forth such participants' rights pursuant
     thereto and the grants pursuant to those plans shall continue in effect
     on the same terms and conditions (subject to the adjustments required by
     this Section 2.5 after giving effect to the Merger), Bionova U.S. shall
     ensure compliance with the terms of the stock option plans and Bionova
     U.S. shall ensure, to the extent required by, and subject to the
     provisions of, such plans and Applicable Laws, that the stock options
     thereunder which qualified as incentive stock options prior to the
     Effective Time continue to qualify as incentive stock options after the
     Effective Time.

          (b)  Prior to the Effective Time, Bionova U.S. shall take all
     corporate action necessary to reserve for issuance a sufficient number
     of shares of Bionova U.S. Common Stock for delivery under the Company
     Stock Options becoming options of Bionova U.S. in accordance with this
     Section 2.5.  If and to the extent required under the Securities Act, as
     soon as practicable after the Effective Time, Bionova U.S. shall file a
     registration statement on Form S-3 or Form S-8 as the case may be (or
     any successor or other appropriate forms), or another appropriate form
     with respect to the shares of Bionova U.S. Common Stock subject to such
     options and shall use its best efforts to maintain the effectiveness of
     such registration statement or registration statements (and maintain the
     current status of the prospectus or prospectuses contained therein) for
     so long as such options remain outstanding.  With respect to those
     individuals who subsequent to the Merger will be subject to the
     reporting requirements under Section 16(a) of the Exchange Act, where
     applicable, Bionova U.S. shall ensure administration of Company Stock
     Options assumed pursuant to this Section 2.5 in a manner that complies
     with Rule 16b-3 promulgated under the Exchange Act if and to the extent
     the Company Option Plan complied with such rule prior to the Merger.

     2.6  Warrants.  At the Effective Time, each then outstanding warrant
(including any warrant comprising part of a unit) to purchase shares of
Company Common Stock shall become a warrant applicable to Bionova U.S., and
the registered holders thereof, after the Effective Time, will have the right
to acquire and receive in lieu of the shares of Company Common Stock
acquirable upon exercise of such warrants and upon payment of the
consideration required to be paid thereunder in connection with the exercise
thereof, such shares of Bionova U.S. Common Stock as would have been issued
pursuant to the Merger in exchange for the number of shares of Company Common
Stock acquirable if such warrants had been exercised immediately prior to the
Effective Time.


                                ARTICLE III

           REPRESENTATIONS AND WARRANTIES REGARDING THE COMPANY

     The Company represents and warrants to Parent, Bionova Mexico, Bionova
U.S. and Sub that:

     3.1  Corporate Organization.  The Company is a corporation duly
organized, validly existing, and in good standing under the laws of the
jurisdiction of its incorporation and has all requisite corporate power and
corporate authority to own, lease, and operate its properties and to carry on
its business as now being conducted.  Other than as contemplated by this
Agreement, no actions or proceedings to dissolve the Company are pending or,
to the best knowledge of the Company, threatened.

     3.2  Qualification.  Each of the Company and the Company Subsidiaries
is duly qualified or licensed to do business as a foreign corporation and each
of the Company and the Company Subsidiaries is in good standing in each of the
jurisdictions set forth opposite its name on Schedule 3.2, which are all the
jurisdictions in which the property owned, leased, or operated by it or the
conduct of its business requires such qualification or licensing, except
jurisdictions in which the failure to be so qualified or licensed would not,
individually or in the aggregate, have a Company Material Adverse Effect.

     3.3  Charter and Bylaws.  The Company has delivered to Bionova U.S.
accurate and complete copies of (i) the charter and bylaws of each of the
Company and the Subsidiaries as currently in effect and (ii) the stock records
of each of the Subsidiaries.  Such records accurately reflect the stock
ownership of the Subsidiaries.  Neither the Company nor any Subsidiary is in
violation of any provision of its charter or bylaws.

the Company consists of 60,000,000 shares of Common Stock, par value $0.01 per

securities, options, warrants, equity equivalents, interests, or rights.  The
Company is not a party to, and is not aware of, any voting agreement, voting
trust, or similar agreement or arrangement relating to any class or series of
its capital stock.  The classes of Company Stock denominated as Company Common
Stock and Company Convertible Exchangeable Preferred Stock are each listed for
trading and trade on the NASDAQ NMS.

     3.5  Authority Relative to This Agreement.  The Company has full
corporate power and corporate authority to execute, deliver, and perform this
Agreement and the Ancillary Documents to which it is a party and, subject to
the approval of this Agreement by the holders of Company Common Stock in

execution, delivery, and performance by the Company of this Agreement and the
Ancillary Documents to which it is a party, and the consummation by it of the

accordance with Applicable Law and the Company's Certificate of Incorporation)
are required on the part of the Company to authorize the execution, delivery,
and performance by the Company of this Agreement and such Ancillary Documents
and the consummation by it of the transactions contemplated hereby and
thereby.  This Agreement has been duly executed and delivered by the Company
and constitutes, and each Ancillary Document executed or to be executed by the
Company has been, or when executed will be, duly executed and delivered by the
Company and constitutes, or when executed and delivered will constitute, a
valid and legally binding obligation of the Company, enforceable against the
Company in accordance with their respective terms, except that such
enforceability may be limited by (i) applicable bankruptcy, insolvency,
reorganization, moratorium, and similar laws affecting creditors' rights
generally, (ii) fiduciary obligations under the laws of the jurisdiction of
its incorporation, (iii) equitable principles which may limit the availability
of certain equitable remedies (such as specific performance) in certain
instances, and (iv) public policy considerations with respect to the
enforceability of rights of indemnification.

     3.6  Noncontravention.  The execution, delivery, and performance, as
the case may be, by the Company or the Company Subsidiaries of this Agreement
and the Ancillary Documents to which it is a party and the consummation by it
of the transactions contemplated hereby and thereby do not and will not,
subject to any consents, waivers or approvals to be effective at the Closing
Date and as may be listed on Schedule 3.6, (i) conflict with or result in a
violation of any provision of the charter or bylaws of the Company or any
Company Subsidiary, (ii) conflict with or result in a violation of any
provision of, or constitute (with or without the giving of notice or the
passage of time or both) a default under, or give rise (with or without the
giving of notice or the passage of time or both) to any right of termination,
cancellation, or acceleration under, or require any consent, approval,
authorization or waiver of, or notice to, any party to, any material bond,

respective properties may be bound or any material Permit held by the Company
or any Company Subsidiary, (iii) result in the creation or imposition of any
Encumbrance upon the properties of the Company or any Company Subsidiary, or
(iv) assuming compliance with the matters referred to in Section 3.7, violate
any Applicable Law binding upon the Company or any Company Subsidiary.

     3.7  Governmental Approvals.  No consent, approval, order, or
authorization of, or declaration, filing, or registration with, any
Governmental Entity is required to be obtained or made by the Company or any
Subsidiary in connection with the execution, delivery, or performance by the

consents, approvals, orders, or authorizations which, if not obtained, and
such declarations, filings, or registrations which, if not made, would not,
individually or in the aggregate, have a Company Material Adverse Effect.

     3.8  Company Subsidiaries.

          (a)  Except as set forth on Schedule 3.8, the Company does not
     own, directly or indirectly, any capital stock or other securities of
     any corporation or have any direct or indirect equity or ownership
     interest in any other person, other than the Company Subsidiaries,
     excluding for this purpose mutual funds.  Schedule 3.8 lists each
     Company Subsidiary, the jurisdiction of incorporation of each Company
     Subsidiary, and the authorized and outstanding capital stock of each
     Company Subsidiary.  Each Company Subsidiary is a corporation duly
     organized, validly existing, and in good standing under the laws of the
     jurisdiction of its incorporation.  Each Company Subsidiary has all
     requisite corporate power and corporate authority to own, lease, and
     operate its properties and to carry on its business as now being
     conducted.  No actions or proceedings to dissolve any Company Subsidiary
     are pending.

          (b)  Except as otherwise indicated on Schedule 3.8, all the
     outstanding capital stock of each Company Subsidiary is owned directly
     by the Company, free and clear of all Encumbrances.  All outstanding
     shares of capital stock of each Company Subsidiary have been validly
     issued and are fully paid and nonassessable.  No shares of capital stock
     of any Company Subsidiary are subject to, nor have any been issued in
     violation of, preemptive or similar rights.

          (c)  Except as set forth on Schedule 3.8, there are (and as of
     the Closing Date there will be) outstanding (i) no shares of capital
     stock or other voting securities of any Company Subsidiary, (ii) no
     securities of the Company or any Company Subsidiary convertible into or
     exchangeable for shares of capital stock or other voting securities of
     any Company Subsidiary, (iii) no options, warrants or other rights
     (including preemptive rights) to acquire from the Company or any Company
     Subsidiary, and no obligation of the Company or any Company Subsidiary
     to issue or sell, any shares of capital stock or other voting securities
     of any Company Subsidiary or any securities convertible into or
     exchangeable for such capital stock or voting securities, and (iv) no
     equity equivalents, interests in the ownership or earnings, or other
     similar rights of or with respect to any Company Subsidiary.  There are
     (and as of the Closing Date there will be) no outstanding obligations of
     the Company or any Company Subsidiary to repurchase, redeem, or
     otherwise acquire any of the foregoing shares, securities, options,
     equity equivalents, interests, or rights.

     3.9  Inapplicability of Section 203.  The Board of Directors of the
Company has taken all actions so that the restrictions contained in Section
203 of the State Law applicable to a "business combination" (as defined
therein) will not apply to the execution, delivery or performance of this
Agreement or the consummation of the Merger or the other transactions
contemplated by this Agreement.

     3.10 SEC Filings.  The Company has filed with the Securities and
Exchange Commission all forms, reports, schedules, statements, and other
documents required to be filed by it under the Securities Act, the Exchange
Act, and all other federal securities laws.  All such forms, reports,
schedules, statements, and other documents (including all amendments thereto)
filed by the Company with the Securities and Exchange Commission are herein
collectively referred to as the "SEC Filings".  The Company has delivered to
or made available for inspection by Bionova U.S. accurate and complete copies
of all the SEC Filings in the form filed by the Company with the Securities
and Exchange Commission since December 31, 1992.  The SEC Filings, including,
without limitation, the financial statements, financial statement footnotes
and financial statement schedules included or incorporated by reference
therein, at the time filed, complied in all material respects with all
applicable requirements of federal securities laws.  None of the SEC Filings,
including, without limitation, any financial statements or schedules included
therein, at the time filed, contained any untrue statement of a material fact
or omitted to state any material fact required to be stated therein or
necessary in order to make the statements contained therein, in light of the
circumstances under which they were made, not misleading.  All material
contracts of the Company and the Subsidiaries required to be filed in the
Company's filings with the SEC under Item 601 of Regulation S-K promulgated by
the SEC have been included in the SEC Filings.  The audited consolidated
financial statements and unaudited consolidated interim financial statements
of the Company included in the SEC Filings present fairly, in conformity with
generally accepted accounting principles applied on a consistent basis (except
as may be indicated in the notes thereto), the consolidated financial position
of the Company as of the dates thereof and its consolidated results of
operations and cash flows for the periods then ended (subject to normal
year-end audit adjustments in the case of any unaudited interim financial
statements).  The Company shall deliver to Bionova U.S. as soon as they become
available accurate and complete copies of all forms, reports, and other
documents furnished by it to its stockholders generally or filed by it with
the Securities and Exchange Commission subsequent to the date hereof and prior
to the Closing Date.

     3.11 Absence of Undisclosed Liabilities.  Except as and to the extent
disclosed in the SEC Filings filed prior to the date hereof, as of
September 30, 1995, neither the Company nor any Subsidiary had any liabilities
or obligations (whether accrued, absolute, contingent, unliquidated, or
otherwise, whether or not known to the Company or any Subsidiary, and whether
due or to become due) material to the Company and the Company's Subsidiaries
taken as a whole.  Since September 30, 1995, neither the Company nor any
Subsidiary has incurred any such material liabilities or obligations, other
than those incurred in the ordinary course of business consistent with past
practice or pursuant to or as contemplated by this Agreement.

     3.12 Absence of Certain Changes.   Except as disclosed in the SEC
Filings filed prior to the date hereof or as disclosed on Schedule 3.12, since
September 30, 1995, (i) there has not been any change, development, or effect,
individually or in the aggregate, that has had, or might reasonably be
expected to have, a Company Material Adverse Effect; (ii) the businesses of
each of the Company and each of the Subsidiaries have been conducted only in
the ordinary course consistent with past practice; (iii) neither the Company
nor any Subsidiary has incurred any material liability, engaged in any
material transaction, or entered into any material agreement outside the
ordinary course of business consistent with past practice; (iv) neither the
Company nor any Subsidiary has suffered any material loss, damage,
destruction, or other casualty to any of its assets (whether or not covered by
insurance); and (v) neither the Company nor any Subsidiary has taken any of
the actions set forth in Section 6.2 except as permitted thereunder.

     3.13 Tax Matters.

          (a)  Except as disclosed on Schedule 3.13:

               (i)  the Company and each Company Subsidiary have (and as
          of the Closing Date will have) duly filed all material federal,
          state, local, and foreign Tax Returns required to be filed by or
          with respect to them with the IRS or other applicable Taxing
          authority, and no extensions with respect to such Tax Returns have
          (or as of the Closing Date will have) been requested or granted;

               (ii) the Company and each Company Subsidiary have (and as
          of the Closing Date will have) paid, or adequately reserved
          against in its financial statements included as part of its SEC
          Filings, all Taxes due, or claimed by any Taxing authority to be
          due, from or with respect to them, except Taxes that are being
          contested in good faith by appropriate legal proceedings and for
          which adequate reserves have been set aside as disclosed on
          Schedule 3.13;

               (iii)     there has been no issue raised or adjustment proposed
          (and none is pending) by the IRS or any other Taxing authority in
          connection with any of such Tax Returns;

               (iv) the Company and each Company Subsidiary have (and as
          of the Closing Date will have) made all deposits required with
          respect to Taxes;

               (v)  the federal income Tax Returns of the Company and the
          Subsidiaries have not been audited by the IRS; and

               (vi) no waiver or extension of any statute of limitations
          as to any federal, state, local, or foreign Tax matter has been
          given by or requested from the Company or any Company Subsidiary.

     3.14 Compliance With Laws.  Except as disclosed in the SEC Filings
filed prior to the date hereof, the Company and the Company Subsidiaries have
complied in all material respects with all Applicable Laws (including without
limitation Applicable Laws relating to securities, properties, business
products, manufacturing processes, advertising and sales practices, employment
practices, terms and conditions of employment, wages and hours, safety,
occupational safety, health, environmental protection, product safety, and
civil rights) relating to any material aspect of the Company's or a Company
Subsidiary's business.  Neither the Company nor any Company Subsidiary has
received any written notice, which has not been dismissed or otherwise
disposed of, that the Company or any Company Subsidiary has not so complied. 
Neither the Company nor any Company Subsidiary is charged or, to the best
knowledge of the Company, threatened with, or, to the best knowledge of the
Company, under investigation with respect to, any violation of any Applicable
Law relating to any aspect of the business of the Company or any Company
Subsidiary.

     3.15 Legal Proceedings.  Except as disclosed on Schedule 3.15, there
are no Proceedings pending or, to the best knowledge of the Company,
threatened against or involving the Company or any Company Subsidiary (or, to
the Company's knowledge, any of their respective directors or officers in
connection with the business or affairs of the Company or any Company
Subsidiary) or any properties or rights of the Company or any Company
Subsidiary except (i) as disclosed in the SEC Filings filed prior to the date
hereof, (ii) for any Proceedings that pertain to routine claims by persons
other than Governmental Entities that are covered by insurance (subject to
applicable insurance deductibles), and (iii) for Proceedings which,
individually or in the aggregate, if prosecuted to judgment, would not have a
Company Material Adverse Effect.  Neither the Company nor any Company
Subsidiary is subject to any judgment, order, writ, injunction, or decree of
any Governmental Entity which has had or is reasonably likely to have a
Company Material Adverse Effect.  There are no Proceedings pending or, to the
best knowledge of the Company, threatened seeking to restrain, prohibit, or
obtain damages or other relief in connection with this Agreement or the
transactions contemplated hereby.

     3.16 Title to Properties.  Each of the Company and the Company
Subsidiaries has good and indefeasible title, and in the case of real property
insurable title, to all material properties (real, personal, and mixed,
tangible and intangible) it owns or purports to own, including without
limitation the properties reflected in its books and records and in the latest
balance sheet of the Company included in the SEC Filings filed prior to the
date hereof, other than those disposed of after the date of such balance sheet
in the ordinary course of business consistent with past practice, free and
clear of all Encumbrances, except (i) as disclosed in the SEC Filings filed
prior to the date hereof, and (ii) liens for Taxes not yet due and payable. 
Except as disclosed on Schedule 3.16, no financing statement (or other
instrument sufficient or effective as a financing statement) under the Uniform
Commercial Code with respect to any properties of the Company or any Company
Subsidiary has been filed and is effective in any jurisdiction, and the
Company and the Company Subsidiaries have not signed any such financing
statement (or other instrument) or any mortgage or security agreement
authorizing any secured party thereunder to file any such financing statement
(or other instrument).  Neither the whole nor any part of the Company's or any
Company Subsidiary's property is subject to any pending or, to the Company's
knowledge, threatened condemnation or similar proceeding.

     3.17 Sufficiency and Condition of Properties.  The material properties
owned, leased, or used by the Company and the Company Subsidiaries are (i) in
the case of tangible properties, in good operating condition and repair
(ordinary wear and tear excepted) and have been maintained in accordance with
standard industry practice, (ii) suitable for the purposes used, and (iii)
adequate and sufficient for the normal operation of the Company's and the
Company Subsidiaries' businesses, as presently conducted.  The Company and the
Company Subsidiaries own or have a valid leasehold interest in, or otherwise
have a valid right to use, all such properties.  The lessee under each such
lease is not in breach of or in default under such lease.  Such properties and
their uses conform in all material respects to all Applicable Laws, except for
such minor variations as do not impair or interfere with the use of such
properties for the purposes for which they are employed and the Company and
the Company Subsidiaries have not received any notice to the contrary.  All
such tangible properties are in the Company's or a Company Subsidiary's
possession or under their control.

     3.18 Intellectual Property.

          (a)  Set forth on Schedule 3.18 is a list of all Intellectual
     Property owned, held, or used by the Company or any Company Subsidiary. 
     Schedule 3.18 specifies, as applicable: (i) the nature of such
     Intellectual Property; (ii) the owner of such Intellectual Property;
     (iii) the jurisdictions by or in which such Intellectual Property is
     recognized without regard to registration or has been issued or
     registered or in which an application for such issuance or registration
     has been filed, including the respective registration or application
     numbers; and (iv) all licenses, sublicenses, and other agreements to
     which the Company or any Company Subsidiary is a party and pursuant to
     which the Company, any Company Subsidiary, or any other person is
     authorized to use such Intellectual Property, including the identity of
     all parties thereto, a description of the nature and subject matter
     thereof, the applicable royalty, and the term thereof.  Except as noted
     in Schedule 3.18, all maintenance fees/annuities have been paid and
     renewals thereof have been duly made with respect to such applications,
     patents and registrations.

          (b)  The listed Intellectual Property constitutes all
     Intellectual Property necessary for the operation of the Company's
     business and that of the Subsidiaries as presently conducted.  The
     Company or a Company Subsidiary has good and indefeasible title to or is
     validly licensed to use all such Intellectual Property.  Except as noted
     in Schedule 3.18, each item of such Intellectual Property is in full
     force and effect, the Company or such Company Subsidiary is in
     compliance with all its obligations with respect thereto, and, to the
     best knowledge of the Company, no event has occurred which permits, or
     upon the giving of notice or the passage of time or otherwise would
     permit, revocation or termination of any thereof.  During the
     prosecution of the U.S. patents listed in Schedule 3.18, the Company
     complied with its Rule 56 disclosure obligations.  Other than as
     identified in Schedule 3.15 hereto, there are no (i) Proceedings
     pending, (ii) to the best knowledge of the Company, Proceedings
     threatened against the Company or any Company  Subsidiary, or (iii) to
     the best knowledge of the Company, notices received by the Company or
     any Company Subsidiary from another person, asserting that (x) use by
     the Company or a Company Subsidiary of any of such Intellectual Property
     (y) the making, producing, using or selling of any commercial product of
     the Company or any Company Subsidiary, or (z) the making, producing,
     using or selling of any experimental product of the Company or any
     Company Subsidiary, infringes the rights of any other person.  To the
     best of the knowledge of the Company, the (x) use by the Company or a
     Company Subsidiary of any of such Intellectual Property (y) the making,
     producing, using or selling of any commercial product of the Company or
     any Company Subsidiary, or (z) the making, producing, using or selling
     of any experimental product of the Company or any Company Subsidiary,
     does not infringe the rights of any other person.  To the best knowledge
     of the Company, none of such Intellectual Property is being infringed
     upon by any other person.  None of such Intellectual Property owned by
     the Company or any Company Subsidiary and, to the best of Company's
     knowledge, none of such Intellectual Property held or used by the
     Company or any Company Subsidiary is subject to any outstanding
     judgment, order, writ, injunction, or decree of any Governmental Entity,
     or any agreement, arrangement, or understanding, written or oral,
     restricting the scope or use thereof.  To the best knowledge of the
     Company, other than as identified on Schedule 3.15 the conduct of the
     Company's and the Subsidiaries' businesses at any time prior to the
     Closing Date did not, and the conduct of such businesses on a basis
     consistent with past practice as of the Closing Date will not, infringe
     upon or otherwise misappropriate any Intellectual Property of any other
     person.

          (c)  The Company has provided Parent with a complete copy of the
     option/license agreement (the "Option/License Agreement") between
     Advanced Genetic Sciences, Inc. ("AGS") and Garching Instruments
     ("Garching"), which has not been amended or supplemented except to the
     extent indicated in the correspondence identified in Schedule 3.18-1. 
     Schedule 3.18-1 is a complete list of all correspondence between the
     Company and Garching defining royalty rates under the Option/License
     Agreement. To the best of the Company's knowledge, the Option/License
     Agreement is in full force and effect, and is enforceable by the
     Company.  To the best of the Company's knowledge and belief, Garching
     was duly authorized by the Max-Planck Institute to enter the
     Option/License Agreement on Max-Planck's behalf with AGS.  The Company
     has made all required royalty payments in a timely manner to Garching
     pursuant to the Option/License Agreement.  The Company exercised its
     option under the Option/License Agreement by providing Garching with
     written notice of same, and now is licensed under that agreement.  The
     Company has made available to Parent's counsel copies of all
     correspondence between Max-Planck or Garching on the one hand, and the
     Company or AGS on the other.  To the best of the Company's knowledge and
     belief, there exist only five licenses under the Max-Planck technology
     that is the subject of the Option/License Agreement.  To the best of the
     Company's knowledge and belief, the licensees are Hoechst, Bayer, Plant
     Genetic Systems, Keygene and the Company.  The only sublicensee under
     the Company's Option/License Agreement is Hilleshog.  To the best of the
     Company's knowledge and belief, there are no patents or patent
     applications owned by Max-Planck which dominate the patents or patent
     applications licensed to AGS in the Option/License Agreement.  AGS is a
     wholly owned subsidiary of the Company.  By change of name AGS is now
     known as DNA Plant Technologies, Inc., which name has been changed to
     DNAP Technologies, Inc.  To the best of the Company's knowledge and
     belief, none of the motions filed by the parties to the interference
     proceedings involving the Max-Planck transformation technology has yet
     been decided by the United States Patent and Trademark Office.  To the
     best of the Company's knowledge and belief, Max-Planck has a priority
     position in connection with Max-Planck's transformation technology
     patent filings (corresponding to the filings that are the subject of the
     interference proceedings referenced in the preceding sentence) in
     Europe, Australia, Israel and Japan.  To the best of the Company's
     knowledge and belief, the contract between Gent University and Monsanto
     provided to Bionova U.S. or its counsel by the Company, which contract
     was filed in the above-referenced interference proceedings, does not in
     any way reduce the rights of the Company pursuant to the Option/License
     Agreement.

          (d)  Schedule 3.18-2 is a complete list of all of the Company's
     research or license agreements in which the Company is the licensee.  To
     the best of the Company's knowledge, each of the agreements listed in
     Schedule 3.18-2 is valid and subsisting and is enforceable by the
     Company (except as the enforceability thereof may be limited by
     bankruptcy, insolvency, bank moratorium or similar laws affecting
     creditors' rights generally and laws restricting the availability of
     equitable remedies and may be subject to general principles of equity
     whether or not such enforceability is considered in a proceeding at law
     or equity), and none of these agreements has been amended or
     supplemented to include terms or conditions not disclosed to Bionova
     U.S.  To the best of the Company's knowledge, the Company is not in
     material breach of the agreements identified in Schedule 3.18-2 except
     as noted in Schedule 3.15.

          (e)  Schedule 3.18-3 is a complete list of all license agreements
     of the Company's Transwitch Technology.  The Company's Transwitch
     patents were developed without the use of any government grant, and the
     Company has no obligation to assign or license the Transwitch technology
     to any governmental entity.  To the best of the Company's knowledge and
     belief, Townsend & Townsend has no documents relating to the Transwitch
     patents and pending patent applications other than documents that are
     part of the U.S. Patent and Trademark Office file histories, or
     correspondence with the Company.  To the best of the Company's knowledge
     and belief, all of the Company's patents are valid, and the Company's
     Transwitch patents cover sense suppression technology as claimed in the
     patents.

          (f)  The Confidential Settlement Agreement between the Company
     and Monsanto relating to the suit brought by Monsanto against the
     Company in the District of Delaware, C.A. No. 95-278 LON, does not
     change or alter any of the material terms of the Consent Judgment
     entered in that action except as noted in Schedule 3.18-4, which
     schedule will be prepared in a manner consistent with the requirements
     of such Confidential Settlement Agreement.

     3.19 Permits.  Except as set forth in Schedule 3.19, (i) the Company
and the Company Subsidiaries hold all the Permits materially necessary or
required for the conduct of the business of the Company and the Company
Subsidiaries as currently conducted; (ii) each of such Permits is in full
force and effect, the Company and the Company Subsidiaries are in compliance
with all their obligations with respect thereto, and, to the best knowledge of
the Company, no event has occurred which permits, or with or without the
giving of notice or the passage of time or both would permit, the revocation
or termination of any thereof; and (iii) no notice has been issued by any
Governmental Entity and no Proceeding is pending or, to the best knowledge of
the Company, threatened with respect to any alleged failure by the Company and
the Company Subsidiaries to have any Permit the absence of which would have a
Company Material Adverse Effect.

     3.20 Agreements.

          (a)  All agreements, arrangements, and understandings of any
     nature (written or oral, formal or informal) (collectively, for purposes
     of this Section, "agreements") to which the Company or any Company
     Subsidiary is a party or by which the Company or any Company Subsidiary
     or any of their respective properties is otherwise bound, that are
     material to the business, assets, results of operations, condition
     (financial or otherwise), or prospects of the Company and the Company
     Subsidiaries considered as a whole, and that provide for annual payments
     or receipts in excess of $100,000, are listed either in Part IV of the
     Company's Annual Report on Form 10-K for the fiscal year ended December
     31, 1994 included in the SEC Filings or on Schedule 3.20.

          (b)  The Company has made available to Bionova U.S. accurate and
     complete copies of the agreements listed in Part IV of the Company's
     Annual Report on Form 10-K for the fiscal year ended December 31, 1994
     and on Schedule 3.20.  Each of such agreements is a valid and binding
     agreement of the Company and the Company Subsidiaries (to the extent
     each is a party thereto) and (to the best knowledge of the Company) the
     other party or parties thereto, enforceable against the Company and the
     Company Subsidiaries (to the extent each is a party thereto) and (to the
     best knowledge of the Company) such other party or parties in accordance
     with its terms, except that such enforceability may be limited by
     (i) applicable bankruptcy, insolvency, reorganization, moratorium, and
     similar laws affecting creditors' rights generally, (ii) fiduciary
     obligations under the laws of the jurisdiction of its incorporation,
     (iii) equitable principles which may limit the availability of certain
     equitable remedies (such as specific performance) in certain instances,
     and (iv) public policy considerations with respect to the enforceability
     of rights of indemnification.  Neither the Company nor any Company
     Subsidiary is in breach of or in default under, nor has any event
     occurred which (with or without the giving of notice or the passage of
     time or both) would constitute a default by the Company or any Company
     Subsidiary under, any material provision of any of such agreements, and
     neither the Company nor any Company Subsidiary has received any notice
     from, or given any notice to, any other party indicating that the
     Company or any Company Subsidiary is in breach of or in default under
     any of such agreements.  To the best knowledge of the Company, no other
     party to any of such agreements is in material breach of or in material
     default under such agreements, nor has any assertion been made by the
     Company or any Company Subsidiary of any such breach or default.

          (c)  Neither the Company nor any Company Subsidiary has received
     notice of any plan or intention of any other party to any agreement to
     exercise any right of offset with respect to, or any right to cancel or
     terminate, any agreement, and neither the Company nor any Company
     Subsidiary knows of any fact or circumstance that would justify the
     exercise by any such other party of such a right other than the
     automatic termination of such agreement in accordance with its terms. 
     Neither the Company nor any Company Subsidiary currently contemplates,
     or has reason to believe any other person currently contemplates, any
     amendment or change to any agreement, which amendment or change could
     have a Company Material Adverse Effect.

     3.21 ERISA.

          (a)  Set forth on Schedule 3.21 is a list identifying each
     "employee benefit plan", as defined in Section 3(3) of ERISA, (i) which
     is subject to any provision of ERISA, (ii) which is maintained,
     administered, or contributed to by the Company or any affiliate of the
     Company, and (iii) which covers any employee or former employee of the
     Company or any affiliate of the Company or under which the Company or
     any affiliate of the Company has any liability.  The Company has
     delivered to Bionova U.S. accurate and complete copies of such plans
     (and, if applicable, the related trust agreements) and all amendments
     thereto and written interpretations thereof, together with (i) the three
     most recent annual reports (Form 5500 including, if applicable,
     Schedule B thereto) prepared in connection with any such plan and
     (ii) the most recent actuarial valuation report prepared in connection
     with any such plan.  Such plans are referred to in this Section as the
     "Employee Plans".  For purposes of this Section only, an "affiliate" of
     any person means any other person which, together with such person,
     would be treated as a single employer under Section 414 of the Code. 
     The only Employee Plans which individually or collectively would
     constitute an "employee pension benefit plan" as defined in Section 3(2)
     of ERISA are identified as such on Schedule 3.21.

          (b)  Except as otherwise identified on Schedule 3.21, (i) no
     Employee Plan constitutes a "multiemployer plan", as defined in
     Section 3(37) of ERISA (for purposes of this Section, a "Multiemployer
     Plan"), (ii) no Employee Plan is maintained in connection with any trust
     described in Section 501(c)(9) of the Code, (iii) no Employee Plan is
     subject to Title IV of ERISA or to the minimum funding standards of
     ERISA and the Code, and (iv) during the past five years, neither the
     Company nor any of its affiliates have made or been required to make
     contributions to any Multiemployer Plan.  There are no accumulated
     funding deficiencies as defined in Section 412 of the Code (whether or
     not waived) with respect to any Employee Plan.  The fair market value of
     the assets held with respect to each Employee Plan that is a defined
     benefit plan and employee pension benefit plan, as defined in
     Section 3(2) of ERISA, exceeds the actuarially determined present value
     of all benefit liabilities accrued under such Employee Plan (whether or
     not vested) determined using reasonable actuarial assumptions.  Neither
     the Company nor any affiliate of the Company has incurred any material
     liability under Title IV of ERISA arising in connection with the
     termination of, or complete or partial withdrawal from, any plan covered
     or previously covered by Title IV of ERISA.  The Company and all of the
     affiliates of the Company have paid and discharged promptly when due all
     liabilities and obligations arising under ERISA or the Code of a
     character which if unpaid or unperformed might result in the imposition
     of a lien against any of the assets of the Company or any Subsidiary. 
     To the knowledge of the Company, nothing done or omitted to be done and
     no transaction or holding of any asset under or in connection with any
     Employee Plan has or will make the Company or any Subsidiary or any
     director or officer of the Company or any Subsidiary subject to any
     liability under Title I of ERISA or liable for any Tax pursuant to
     Section 4975 of the Code that could have a Company Material Adverse
     Effect.  To the knowledge of the Company, there are no threatened or
     pending claims by or on behalf of the Employee Plans, or by any
     participant therein, alleging a breach or breaches of fiduciary duties
     or violations of Applicable Laws which could result in liability on the
     part of the Company, its officers or directors, or such Employee Plans,
     under ERISA or any other Applicable Law and there is no basis for any
     such claim.

          (c)  Each Employee Plan which is intended to be qualified under
     Section 401(a) of the Code is so qualified and has been so qualified
     since the date of its adoption, and each trust forming a part thereof is
     exempt from Tax pursuant to Section 501(a) of the Code.  Set forth on
     Schedule 3.21 is a list of the most recent IRS determination letters
     with respect to any such Plans, accurate and complete copies of which
     letters have been delivered to Bionova U.S.  To the best of the
     Company's knowledge, each Employee Plan has been maintained in
     compliance with its terms and with the requirements prescribed by all
     Applicable Laws, including but not limited to ERISA and the Code, which
     are applicable to such Plans.

          (d)  There is set forth on Schedule 3.21 a list of each
     employment, severance, or other similar contract, arrangement, or policy
     and each plan or arrangement (written or oral) providing for insurance
     coverage (including any self-insured arrangements), workers'
     compensation, disability benefits, supplemental unemployment benefits,
     vacation benefits, retirement benefits, deferred compensation, profit-
     sharing, bonuses, stock options, stock appreciation rights, or other
     forms of incentive compensation or post-retirement insurance,
     compensation, or benefits which (i) is not an Employee Plan, (ii) is
     entered into, maintained, or contributed to, as the case may be, by the
     Company or any affiliate of the Company, and (iii) covers any employee
     or former employee of the Company or any affiliate of the Company or
     under which the Company or any affiliate of the Company has any
     liability.  Such contracts, plans, and arrangements as are described in
     the preceding sentence are referred to for purposes of this Section as
     the "Benefit Arrangements".  Each Benefit Arrangement has been
     maintained in substantial compliance with its terms and with the
     requirements prescribed by Applicable Laws.

          (e)  To the best of the Company's knowledge, neither the Company
     nor any affiliate of the Company has performed any act or failed to
     perform any act, and there is no contract, agreement, plan, or
     arrangement covering any employee or former employee of the Company or
     any affiliate of the Company, that, individually or collectively, could
     give rise to the payment of any amount that would not be deductible
     pursuant to the terms of Section 162(a)(1) or 280G of the Code, or could
     give rise to any penalty or excise Tax pursuant to Section 4980B or 4999
     of the Code.

          (f)  Except as disclosed on Schedule 3.21, there has been no
     amendment, written interpretation, or announcement (whether or not
     written) by the Company or any affiliate of the Company of or relating
     to, or change in employee participation or coverage under, any Employee
     Plan or Benefit Arrangement which would increase materially the expense
     of maintaining such Employee Plan or Benefit Arrangement above the level
     of the expense incurred in respect thereof for the fiscal year ended
     December 31, 1994.

     3.22 Environmental Matters.

          (a)  Except as disclosed in the SEC Filings filed prior to the
     date hereof or as previously disclosed on Schedule 3.22 and except for
     matters that in the aggregate would not have a Company Material Adverse
     Effect:

               (i)  the properties, operations, and activities of the
          Company and the Company Subsidiaries comply with all Applicable
          Environmental Laws (as defined below);

               (ii) the Company and the Company Subsidiaries and the
          properties, operations, and activities of the Company and the
          Company Subsidiaries are not subject to any existing, pending, or,
          to the best knowledge of the Company, threatened Proceeding under,
          or to any remedial obligations under, any Applicable Environmental
          Laws;

               (iii)     all Permits, if any, required to be obtained by the
          Company or any Company Subsidiary under any Applicable
          Environmental Laws in connection with any aspect of the business
          of the Company or the Company Subsidiaries, including without
          limitation those relating to the treatment, storage, disposal, or
          release of a hazardous material (as defined below), have been duly
          obtained and are in full force and effect, and the Company and the
          Company Subsidiaries are in compliance with the terms and
          conditions of all such Permits;

               (iv) the Company and the Company Subsidiaries have
          satisfied and are currently in compliance with all financial
          responsibility requirements applicable to their respective

     and the Comision Nacional Bancaria y de Valores, as the case may be, all
     forms, reports, schedules, statements, and other documents required to
     be filed by it under the Securities Act, the Exchange Act, and all other
     U.S. federal and Mexican securities laws.  All such forms, reports,
     schedules, statements, and other documents (including all amendments
     thereto) filed by Parent with the Securities and Exchange Commission or
     the Comision  Nacional Bancaria y de Valores are herein collectively
     referred to as the "Filings."  Parent has delivered to or made available
     for inspection by the Company accurate and complete copies of all the
     Filings in the form filed by Parent with the Securities and Exchange
     Commission or the Comision Nacional Bancaria y de Valores since December
     31, 1992.  The Filings, at the time filed, complied in all material
     respects with all applicable requirements of United States or Mexican
     securities laws, as the case may be.  None of the Filings, including,
     without limitation, any financial statements or schedules included
     therein, at the time filed, contained any untrue statement of a material
     fact or omitted to state any material fact required to be stated therein
     or necessary in order to make the statements contained therein, in light
     of the circumstances under which they were made, not misleading.  All
     material contracts of Parent have been included in the Filings, except
     for those contracts not required to be filed pursuant to the rules and
     regulations of the Securities and Exchange Commission or the Comision
     Nacional Bancaria y de Valores.

          (b)  The audited consolidated financial statements and unaudited
     consolidated interim financial statements of Parent included in the
     Filings present fairly, in conformity with generally accepted accounting
     principles in effect in Mexico or the United States (as specified
     therein) applied on a consistent basis (except as may be indicated in
     the notes thereto), the consolidated financial position of Parent as of
     the dates thereof and its consolidated results of operations and cash
     flows for the periods then ended (subject to normal year-end audit
     adjustments in the case of any unaudited interim financial statements). 
     Parent shall deliver to the Company as soon as they become available
     accurate and complete copies of all forms, reports, and other documents
     furnished by it to its stockholders generally or filed by it with the
     Securities and Exchange Commission or the Comision Nacional Bancaria y
     de Valores subsequent to the date hereof and prior to the Closing Date.

     4.11 Control.  Except as set forth on Schedule 4.11, Bionova Mexico
controls each other member of the Bionova Group as of the date of this
Agreement (which includes the power on its own, without the joinder of any
other person, to direct all material decisions) and, assuming the
effectiveness of this Agreement and the transactions contemplated by it,
Bionova U.S. will so control such Bionova Group members after the Effective
Time.

                      REPRESENTATIONS AND WARRANTIES
                        REGARDING THE BIONOVA GROUP

     Parent, Bionova Mexico, Bionova U.S. and Sub represent and warrant to
the Company that:

     5.1  Corporate Organization.  Each member of the Bionova Group is a
corporation duly organized, validly existing, and in good standing under the
laws of the jurisdiction of its incorporation and has all requisite corporate
power and corporate authority to own, lease, and operate its properties and to

     5.2  Qualification.  Each member of the Bionova Group is duly qualified
or licensed to do business as a foreign corporation, and is in good standing,
in each of the jurisdictions set forth opposite its name on Schedule 5.2,
which are all the jurisdictions in which the property owned, leased, or
operated by it or the conduct of its business requires such qualification or
licensing, except jurisdictions in which the failure to be so qualified or
licensed would not, individually or in the aggregate, have a Bionova Group
Material Adverse Effect.

     5.3  Charter and Bylaws.  Bionova U.S. has delivered to the Company
accurate and complete copies of (i) the charter and bylaws (or other
organizational documents) of each member of the Bionova Group as currently in

Bionova Group will be in violation of any provision of its organizational
documents.

     5.4  Capitalization of the Bionova Group.  Except as set forth on

the Closing Date there will be) no outstanding obligations of the Bionova
Group to repurchase, redeem, or otherwise acquire any of the foregoing shares,
securities, options, equity equivalents, interests, or rights.  Except as set
forth on Schedule 5.4, no member of the Bionova Group is a party to, or is
aware of, any voting agreement, voting trust, or similar agreement or
arrangement relating to any class or series of its capital stock.

     5.5  Financial Statements.  Bionova Mexico has delivered to the Company

as of September 30, 1995, and the related consolidated statement of income for
the nine-month period then ended, as well as, for each material member of the
Bionova Group, such entity's consolidating balance sheet as of September 30,

     5.6  Absence of Undisclosed Liabilities.  No member of the Bionova
Group has any material liability or obligation (whether accrued, absolute,

whether due or to become due), except (i) liabilities reflected on the Bionova

warranty, tort, or infringement), (iii) liabilities arising under executory
contracts entered into in the ordinary course of business (none of which is a
material liability for breach of contract), (iv) liabilities specifically set

          Tax Returns required to be filed by or with respect to it with the
          IRS or other applicable Taxing authority, and no extensions with

          have) been requested or granted;

               (ii) the Bionova Group has (and as of the Closing Date will

          Financial Statements, all Taxes due, or claimed by any Taxing
          authority to be due, from or with respect to it, except Taxes that
          are being contested in good faith by appropriate legal proceedings

          on Schedule 5.8;

               (iii)     there has been no issue raised or adjustment proposed
          (and none is pending) by the IRS or any other Taxing authority in

               (vi) no waiver or extension of any statute of limitations
          as to any federal, state, local, or foreign Tax matter has been
          given by or requested from the Bionova Group.

     5.9  Compliance With Laws.  Except as disclosed on Schedule 5.9,
Bionova Mexico and the Bionova Group has complied in all material respects
with all Applicable Laws (including without limitation Applicable Laws
relating to securities, properties, business products, manufacturing
processes, advertising and sales practices, employment practices, terms and
conditions of employment, wages and hours, safety, occupational safety,
health, environmental protection, product safety, and civil rights) relating
to any material aspect of the Bionova Group's business.  Neither Bionova
Mexico nor any member of the Bionova Group has received any written notice,
which has not been dismissed or otherwise disposed of, that it has not so
complied.  Neither Bionova Mexico nor any member of the Bionova Group is
charged or, to the best knowledge of Bionova U.S., threatened with, or, to the
best knowledge of Bionova U.S., under investigation with respect to, any
violation of any Applicable Law relating to any aspect of the business of
Bionova Mexico or the Bionova Group.

     5.10 Legal Proceedings.  There are no Proceedings pending or, to the
best knowledge of Bionova Mexico and Bionova U.S., threatened against or
involving Bionova Mexico or the Bionova Group (or any of their respective
directors or officers in connection with the business or affairs of Bionova
Mexico or the Bionova Group) or any properties or rights of Bionova Mexico or
the Bionova Group except (i) as disclosed on Schedule 5.10, (ii) for any
Proceedings that pertain to routine claims by persons other than Governmental
Entities that are covered by insurance (subject to applicable insurance
deductibles), and (iii) for Proceedings which, individually or in the
aggregate, if prosecuted to judgment, would not have a Bionova Group Material
Adverse Effect.  Neither Bionova Mexico nor any member of the Bionova Group is
subject to any judgment, order, writ, injunction, or decree of any
Governmental Entity which has had or is reasonably likely to have a Bionova
Group Material Adverse Effect.  There are no Proceedings pending or, to the
best knowledge of Bionova Mexico or Bionova U.S., threatened seeking to
restrain, prohibit, or obtain damages or other relief in connection with this
Agreement or the transactions contemplated hereby.

     5.11 Title to Properties.  Each member of the Bionova Group has good
and indefeasible title, and in the case of real property located in the United
States of America insurable title, to all material properties (real, personal,
and mixed, tangible and intangible) it owns or purports to own, including
without limitation the properties reflected in its books and records and in
the Bionova U.S. Financial Statements, other than those disposed of after the
date of such balance sheet in the ordinary course of business consistent with
past practice, free and clear of all Encumbrances, except (i) as disclosed on
Schedule 5.11, and (ii) liens for Taxes not yet due and payable and (iii) such
imperfections or irregularities of title, if any, as (A) are not substantial
in character, amount, or extent and do not materially detract from the value
of the property subject thereto, (B) do not materially interfere with either
the present or intended use of such property, and (C) do not, individually or
in the aggregate, materially interfere with the conduct of the Bionova Group's
normal operations.  Except as disclosed on Schedule 5.11, no financing
statement (or other instrument sufficient or effective as a financing
statement) under the Uniform Commercial Code or other comparable statute with
respect to any properties of the Bionova Group has been filed and is effective
in any jurisdiction, and no member of the Bionova Group has signed any such
financing statement (or other instrument) or any mortgage or security
agreement authorizing any secured party thereunder to file any such financing
statement (or other instrument).

     5.12 Sufficiency and Condition of Properties.  The material properties
owned, leased, or used by the Bionova Group's business are (i) in the case of
tangible properties, in good operating condition and repair (ordinary wear and
tear excepted) and have been maintained in accordance with standard industry
practice, (ii) suitable for the purposes used, and (iii) adequate and
sufficient for the normal operation of the Bionova Group's business, as
presently conducted.  The members of the Bionova Group own or have a valid
leasehold interest in, or otherwise have a valid right to use, all such
properties.  Such properties and their uses conform in all material respects
to all Applicable Laws, except for such minor variations as do not impair or
interfere with the use of such properties for the purposes for which they are
employed and Bionova U.S. has not, nor has any member of the Bionova Group,
received any notice to the contrary.  All such tangible properties are in the
Bionova Group's possession or under their control.

     5.13 Intellectual Property.

          (a)  Set forth on Schedule 5.13 is a list of all Intellectual
     Property owned, held, or used by the Bionova Group.  Schedule 5.13
     specifies, as applicable: (i) the nature of such Intellectual Property;
     (ii) the owner of such Intellectual Property; (iii) the jurisdictions by
     or in which such Intellectual Property is recognized without regard to
     registration or has been issued or registered or in which an application
     for such issuance or registration has been filed, including the
     respective registration or application numbers; and (iv) all licenses,
     sublicenses, and other agreements to which any member of the Bionova
     Group is a party and pursuant to which any member of the Bionova Group,
     or any other person is authorized to use such Intellectual Property,
     including the identity of all parties thereto, a description of the
     nature and subject matter thereof, the applicable royalty, and the term
     thereof.

          (b)  The listed Intellectual Property constitutes all
     Intellectual Property necessary for the operation of the Bionova Group's
     business as presently conducted.  The Bionova Group has good and
     indefeasible title to or is validly licensed to use all such
     Intellectual Property, free from burdensome restrictions.  Except as
     noted in Schedule 5.13, each item of such Intellectual Property is in
     full force and effect, the Bionova Group is in compliance with all its
     obligations with respect thereto, and, to the best knowledge of Bionova
     U.S., no event has occurred which permits, or upon the giving of notice
     or the passage of time or otherwise would permit, revocation or
     termination of any thereof.  During the prosecution of the U.S. patents
     listed on Schedule 5.13, the Bionova Group complied with its Rule 56
     disclosure obligations.  Other than as identified on Schedule 5.10,
     there are no Proceedings pending or, to the best knowledge of Bionova
     U.S., threatened against the Bionova Group asserting that the use by the
     Bionova Group of any of such Intellectual Property infringes the rights
     of any other person or seeking revocation, termination, or concurrent
     use of any of such Intellectual Property, and there is, to the best
     knowledge of the Bionova U.S., no basis for any such Proceeding.  To the
     best knowledge of the Bionova U.S., none of such Intellectual Property
     is being infringed upon by any other person.  None of such Intellectual
     Property is subject to any outstanding judgment, order, writ,
     injunction, or decree of any Governmental Entity, or any agreement,
     arrangement, or understanding, written or oral, restricting the scope or
     use thereof.  Except as set forth on Schedule 5.13, to the best
     knowledge of Bionova U.S., the conduct of the Bionova Group's business
     at any time prior to the Closing Date did not, and the conduct of such
     business on a basis consistent with past practice as of the Closing Date
     will not, infringe upon or otherwise misappropriate any Intellectual
     Property of any other person.

          (c)  To the best knowledge of Bionova Mexico and Bionova U.S.,
     none of the Bionova Group's commercial products now in the marketplace
     infringes any third-party utility patent, plant patent or plant
     protection certificate.  Schedule 5.13 sets forth a complete list of all
     of the Bionova Group's research or license agreements in which a member
     of the Bionova Group is a licensee.  To the best knowledge of Bionova
     Mexico and Bionova U.S., each of the agreements listed on Schedule 5.13
     is valid and subsisting and is enforceable by the Bionova Group (except
     as the enforceability thereof may be limited by bankruptcy, insolvency,
     bank moratorium or similar laws affecting creditors' rights generally
     and laws restricting the availability of equitable remedies and may be
     subject to general principles of equity whether or not such
     enforceability is considered in a proceeding at law or equity), and none
     of these agreements has been amended or supplemented to include terms or
     conditions not disclosed to the Company.

          (d)  As of the date of this Agreement, those members of the
     Bionova Group using Parent's "Premier Selecion" and "Market Delight"
     trademarks or tradenames have a royalty free arrangement from Parent
     pursuant to which such members are permitted to utilize such trademarks
     or tradenames.  Such arrangement will not be cancelled or reconstituted
     as a royalty bearing arrangement as a result of the consummation of the
     Merger.  Not later than the Effective Time of the Merger, such
     arrangement will be memorialized in a written instrument granting to
     such members of the Bionova Group the right to use all such trademarks
     or tradenames for a perpetual period of time and on a royalty free
     basis.

     5.14 Permits.  Except as set forth on Schedule 5.14, (i) the Bionova
Group holds all the Permits materially necessary or required for the conduct
of the business of the Bionova Group as currently conducted; (ii) each of such
Permits is in full force and effect, the Bionova Group is in compliance with
all its obligations with respect thereto, and, to the best knowledge of
Bionova U.S., no event has occurred which permits, or with or without the
giving of notice or the passage of time or both would permit, the revocation
or termination of any thereof; and (iii) no notice has been issued by any
Governmental Entity and no Proceeding is pending or, to the best knowledge of
Bionova U.S., threatened with respect to any alleged failure by the Bionova
Group to have any Permit the absence of which would have a Bionova Group
Material Adverse Effect.

     5.15 Agreements.

          (a)  All agreements, arrangements, and understandings of any
     nature (written or oral, formal or informal) (collectively, for purposes
     of this Section, "agreements") to which the Bionova Group is a party or
     by which the Bionova Group or any of their respective properties is
     otherwise bound, that are material to the business, assets, results of
     operations, condition (financial or otherwise), or prospects of the
     Bionova Group considered as a whole, and that provide for annual
     payments or receipts in excess of $100,000,  are listed on Schedule
     5.15.

          (b)  Bionova U.S. has delivered to the Company accurate and
     complete copies of the agreements listed on Schedule 5.15.  Each of such
     agreements is a valid and binding agreement of the Bionova Group (to the
     extent each is a party thereto) and (to the best knowledge of Bionova
     U.S.) the other party or parties thereto, enforceable against the
     Bionova Group (to the extent each is a party thereto) and (to the best
     knowledge of Bionova U.S.) such other party or parties in accordance
     with its terms, except that such enforceability may be limited by (i)
     applicable bankruptcy, insolvency, reorganization, moratorium, and
     similar laws affecting creditors' rights generally, (ii) fiduciary
     obligations under the laws of its jurisdiction of incorporation,
     (iii) equitable principles which may limit the availability of certain
     equitable remedies (such as specific performance) in certain instances,
     (iv) public policy considerations with respect to the enforceability of
     rights of indemnification, and (v) priority claims under Mexican law
     with respect to labor claims, taxes, social security payments,
     retirement funds, housing funds and similar items.  No member of the
     Bionova Group is in breach of or in default under, nor has any event
     occurred which (with or without the giving of notice or the passage of
     time or both) would constitute a default by the Bionova Group under, any
     material provision of any of such agreements, and no member of the
     Bionova Group has received any notice from, or given any notice to, any
     other party indicating that the Bionova Group is in breach of or in
     default under any of such agreements.  To the best knowledge of Bionova
     U.S., no other party to any of such agreements is in material breach of
     or in material default under such agreements, nor has any assertion been
     made by the Bionova Group of any such breach or default.

          (c)  No member of the Bionova Group has received notice of any
     plan or intention of any other party to any agreement to exercise any
     right of offset with respect to, or any right to cancel or terminate,
     any agreement, and no member of the Bionova Group knows of any fact or
     circumstance that would justify the exercise by any such other party of
     such a right other than the automatic termination of such agreement in
     accordance with its terms.  No member of the Bionova Group currently
     contemplates, or has reason to believe any other person currently
     contemplates, any amendment or change to any agreement, which amendment
     or change could have a Bionova Group Material Adverse Effect.

     5.16 ERISA.

          (a)  Set forth on Schedule 5.16 is a list identifying each
     "employee benefit plan", as defined in Section 3(3) of ERISA, (i) which
     is subject to any provision of ERISA, (ii) which is maintained,
     administered, or contributed to by Bionova U.S. or any affiliate of
     Bionova U.S., and (iii) which covers any employee or former employee of
     Bionova U.S. or any affiliate of Bionova U.S. or under which Bionova
     U.S. or any affiliate of Bionova U.S. has any liability.  Bionova U.S.
     has delivered to the Company accurate and complete copies of such plans
     (and, if applicable, the related trust agreements) and all amendments
     thereto and written interpretations thereof, together with (i) the three
     most recent annual reports (Form 5500 including, if applicable,
     Schedule B thereto) prepared in connection with any such plan and
     (ii) the most recent actuarial valuation report prepared in connection
     with any such plan.  Such plans are referred to in this Section as the
     "Employee Plans".  For purposes of this Section only, an "affiliate" of
     any person means any other person which, together with such person,
     would be treated as a single employer under Section 414 of the Code. 
     The only Employee Plans which individually or collectively would
     constitute an "employee pension benefit plan" as defined in Section 3(2)
     of ERISA are identified as such on Schedule 5.16.

          (b)  Except as otherwise identified on Schedule 5.16, (i) no
     Employee Plan constitutes a "multiemployer plan", as defined in
     Section 3(37) of ERISA (for purposes of this Section, a "Multiemployer
     Plan"), (ii) no Employee Plan is maintained in connection with any trust
     described in Section 501(c)(9) of the Code, (iii) no Employee Plan is
     subject to Title IV of ERISA or to the minimum funding standards of
     ERISA and the Code, and (iv) during the past five years, neither Bionova
     U.S. nor any of its affiliates have made or been required to make
     contributions to any Multiemployer Plan.  There are no accumulated
     funding deficiencies as defined in Section 412 of the Code (whether or
     not waived) with respect to any Employee Plan.  The fair market value of
     the assets held with respect to each Employee Plan that is a defined
     benefit plan and an employee pension benefit plan, as defined in
     Section 3(2) of ERISA, exceeds the actuarially determined present value
     of all benefit liabilities accrued under such Employee Plan (whether or
     not vested) determined using reasonable actuarial assumptions.  Neither
     Bionova U.S. nor any affiliate of Bionova U.S. has incurred any material
     liability under Title IV of ERISA arising in connection with the
     termination of, or complete or partial withdrawal from, any plan covered
     or previously covered by Title IV of ERISA.  Bionova U.S. and all of the
     affiliates of Bionova U.S. have paid and discharged promptly when due
     all liabilities and obligations arising under ERISA or the Code of a
     character which if unpaid or unperformed might result in the imposition
     of a lien against any of the assets of the Bionova Group.  To the
     knowledge of Bionova Mexico or Bionova U.S., nothing done or omitted to
     be done and no transaction or holding of any asset under or in
     connection with any Employee Plan has or will make the Bionova Group or
     any director or officer of the Bionova Group subject to any liability
     under Title I of ERISA or liable for any Tax pursuant to Section 4975 of
     the Code that could have a Bionova Group Material Adverse Effect.  To
     the knowledge of Bionova Mexico or Bionova U.S., there are no threatened
     or pending claims by or on behalf of the Employee Plans, or by any
     participant therein, alleging a breach or breaches of fiduciary duties
     or violations of Applicable Laws which could result in liability on the
     part of Bionova U.S., its officers or directors, or such Employee Plans,
     under ERISA or any other Applicable Law and there is no basis for any
     such claim.

          (c)  To the knowledge of Bionova Mexico or Bionova U.S., each
     Employee Plan which is intended to be qualified under Section 401(a) of
     the Code is so qualified and has been so qualified since the date of its
     adoption, and each trust forming a part thereof is exempt from Tax
     pursuant to Section 501(a) of the Code.  Set forth on Schedule 5.16 is a
     list of the most recent IRS determination letters with respect to any
     such Plans, accurate and complete copies of which letters have been
     delivered to Bionova U.S.  To the best of the knowledge of Parent,
     Bionova Mexico, Bionova U.S. and Sub, each Employee Plan has been
     maintained in compliance with its terms and with the requirements
     prescribed by all Applicable Laws, including but not limited to ERISA
     and the Code, which are applicable to such Plans.

          (d)  There is set forth on Schedule 5.16 a list of each
     employment, severance, or other similar contract (including any non-
     competition agreement), arrangement, or policy and each plan or
     arrangement (written or oral) providing for insurance coverage
     (including any self-insured arrangements), workers' compensation,
     disability benefits, supplemental unemployment benefits, vacation
     benefits, retirement benefits, deferred compensation, profit-sharing,
     bonuses, stock options, stock appreciation rights, or other forms of
     incentive compensation or post-retirement insurance, compensation, or
     benefits which (i) is not an Employee Plan, (ii) is entered into,
     maintained, or contributed to, as the case may be, by the Bionova Group,
     and (iii) covers any employee or former employee of the Bionova Group. 
     Such contracts, plans, and arrangements as are described in the
     preceding sentence are referred to for purposes of this Section as the
     "Benefit Arrangements".  Each Benefit Arrangement has been maintained in
     substantial compliance with its terms and with the requirements
     prescribed by Applicable Laws.

          (e)  To the knowledge of Bionova Mexico or Bionova U.S., neither
     Bionova U.S. nor any affiliate of Bionova U.S. has performed any act or
     failed to perform any act, and there is no contract, agreement, plan, or
     arrangement covering any employee or former employee of Bionova U.S. or
     any affiliate of Bionova U.S., that, individually or collectively, could
     give rise to the payment of any amount that would not be deductible
     pursuant to the terms of Section 162(a)(1) or 280G of the Code, or could
     give rise to any penalty or excise Tax pursuant to Section 4980B or 4999
     of the Code.

          (f)  Except as disclosed on Schedule 5.16, there has been no
     amendment, written interpretation, or announcement (whether or not
     written) by Bionova U.S. or any affiliate of Bionova U.S. of or relating
     to, or change in employee participation or coverage under, any Employee
     Plan or Benefit Arrangement which would increase materially the expense
     of maintaining such Employee Plan or Benefit Arrangement above the level
     of the expense incurred in respect thereof for the fiscal year ended
     December 31, 1994.

     5.17 Environmental Matters.

     clauses (ii) and (iii) of the immediately preceding sentence in response
     to solicitations and transactions which may, in the reasonable judgement
     of the Board of Directors of the Company, ultimately result, directly or

     7.3  Special Meeting; Proxy Statement.  The Company shall take all
action necessary in accordance with State Law and the Company's Certificate of

cause to be prepared and filed, with the assistance and consent of Bionova
U.S., a proxy statement with the SEC under the Exchange Act.  The term "Proxy
Statement," as used herein means such proxy statement and all amendments and
supplements thereto, if any.  The Company shall use all reasonable best
efforts to have the proxy statement cleared with the SEC as promptly as
practicable after the filing thereof.  As promptly as practicable after the
date hereof, Bionova U.S., with the assistance and consent of the Company,
shall prepare and file with the Securities and Exchange Commission a
registration statement on an appropriate form (which will contain a prospectus
to be used by the Company as the Proxy Statement) for the purpose of
registering under the Securities Act the offering, sale, and delivery of the
Bionova U.S. Common Stock to be issued to the stockholders of the Company
pursuant to the Merger.  The term "Registration Statement", as used herein,
means such registration statement and all amendments and supplements thereto,
if any.  Bionova U.S. shall use all reasonable best efforts to have the
Registration Statement declared effective under the Securities Act as promptly
as practicable after the filing thereof.  Bionova U.S. or the Company, as the
case may be, shall notify the other promptly of the receipt of any comments
on, or any requests for amendments or supplements to, the Proxy Statement or
the Registration Statement by the Securities and Exchange Commission, and each
shall supply the other with copies of all correspondence between it and its
representatives, on the one hand, and the Securities and Exchange Commission
or members of its staff, on the other, with respect to the Proxy Statement or
the Registration Statement.  Bionova U.S. or the Company, as the case may be,
after consultation with and the consent of the other, shall use its reasonable
best efforts to respond promptly to any comments made by the Securities and
Exchange Commission with respect to the Proxy Statement or the Registration
Statement.  The Company shall obtain the approval of Bionova U.S. and Bionova
U.S. shall obtain the approval of the Company, before making any filings with
the Securities and Exchange Commission pertaining to the Proxy Statement or
the Registration Statement or any matter pertaining to this Agreement.

     Parent, Bionova U.S., Sub, and the Company each agrees promptly to
correct any information provided by it for use in the Proxy Statement or the
Registration Statement if and to the extent that such information shall have
become false or misleading in any material respect, and Bionova U.S. further
agrees to take all steps necessary to cause the Proxy Statement or the
Registration Statement (or the prospectus contained therein) as so corrected
to be filed with the Securities and Exchange Commission and to be disseminated
promptly to holders of shares of Company Stock, in each case as and to the
extent required by Applicable Law.  Bionova U.S. shall also take any action
reasonably required to be taken under any applicable state securities laws in
connection with the issuance of Bionova U.S. Common Stock pursuant to the
Merger, and the Company shall furnish all information concerning the Company
and its stockholders as may be reasonably requested in connection with any
such action.

     Bionova U.S. shall prepare and file with the SEC a registration
statement on Form 8-A registering the Bionova U.S. Common Stock as a class of
"equity securities" under the Exchange Act prior to effectiveness of the
Registration Statement.

     7.5  Reasonable Best Efforts.  Each party hereto agrees that it will
not voluntarily undertake any course of action inconsistent with the
provisions or intent of this Agreement and will use its reasonable best
efforts to take, or cause to be taken, all action and to do, or cause to be
done, all things reasonably necessary, proper, or advisable under Applicable
Laws to consummate the transactions contemplated by this Agreement, including,

with or cause to be complied with any requests by the Federal Trade Commission
or the United States Department of Justice for additional information
concerning such transactions, in each case so that the waiting period

the HSR Act shall expire as soon as practicable after the execution and
delivery of this Agreement.  Prior to making any filing under the HSR Act,
each party will obtain the consent of the other party to the content of such
filing, which consent shall not be unreasonably withheld.  Each party hereto
agrees to request, and to cooperate with the other party or parties in
requesting, early termination of any applicable waiting period under the HSR
Act.  The filing fees and other costs of compliance with the HSR Act (other
than each party's attorneys' and accountant's fees and other third party
expenses) shall be borne equally by Bionova U.S. and the Company.

     7.7  Public Announcements.  Except as may be required by Applicable Law
or the National Association of Securities Dealers, Inc., neither Parent,
Bionova U.S. or any member of the Bionova Group, on the one hand, nor the
Company or the Company Subsidiaries, on the other, shall issue any press
release or otherwise make any public statement with respect to this Agreement
or the transactions contemplated hereby without the prior written consent of
the other party (which consent shall not be unreasonably withheld or delayed). 
Any such press release or public statement required by Applicable Law or by
the National Association of Securities Dealers, Inc. shall only be made after
reasonable notice to the other party.

     7.8  Delivery and Amendment of Schedules.  Each of Bionova U.S. and the
Company shall deliver all Schedules relating to the representations and
warranties of such party contained in this Agreement to the other party
simultaneously with the execution of this Agreement, except that (i) the
following schedules may be delivered up to thirty days after the date this
Agreement is signed: Schedules 7.8A, 7.8B, 7.8C, 9.5 and 10.4; and
(ii) Schedules 7.9A and 7.9B may be delivered on February 28, 1996.  Any date
on which a party delivers any such Schedule is referred to as a "Schedule
Delivery Date" for such party.  Each party hereto agrees that, with respect to
the representations and warranties of such party contained in this Agreement,
such party shall have the continuing obligation until the Closing to
supplement or amend promptly the Schedules hereto with respect to any matter
hereafter arising or discovered which, if existing or known on a Schedule
Delivery Date, would have been required to be set forth or described in the
Schedules, including, without limitation, any material development with
respect to any pending on threatened litigation or governmental proceeding
previously disclosed in the Schedules.  For all purposes of this Agreement,
including without limitation for purposes of determining whether the
conditions set forth in Sections 9.1 and 10.1 have been fulfilled, the
Schedules hereto shall be deemed to include only that information contained
therein on a Schedule Delivery Date and shall be deemed to exclude all
information contained in any supplement or amendment thereto; provided,
however, that if the Closing shall occur, then all matters disclosed pursuant
to any such supplement or amendment at or prior to the Closing shall be waived
and no party shall be entitled to make a claim thereon pursuant to the terms
of this Agreement.  In addition to those schedules specifically referenced in
any other section of this Agreement, each of the parties hereto shall be
entitled to deliver to the other as provided in clause (i) above an omnibus
disclosure schedule through which they shall be entitled to supplement any of
the representations and warranties set forth in Articles III, IV and V hereof. 
Any such omnibus disclosure schedule shall be delivered as Schedule 7.8A in
the case of the Company and Schedule 7.8B in the case of Parent, Bionova
Mexico, Bionova U.S. or Sub.  Any documents referred to in either such
Schedule shall be delivered to the other party by the disclosing party
simultaneously with the delivery of Schedule 7.8A or 7.8B, as the case may be. 
Schedule 7.8C referred to above shall consist of documents referenced in the
Schedules to the representations set forth in Articles IV and V together with
certain other documents requested by the Company in a written document request
to Bionova U.S. from the Company (or its counsel) dated January 25, 1996.  The
failure to timely deliver any schedule required to be delivered after the date
hereof shall be deemed a material breach for all purposes hereof.

     7.9  Delivery of 1995 Audited Financial Statements.

          (a)  On or before February 28, 1996, Bionova U.S. shall deliver
     to the Company copies of the Bionova Group's audited consolidated
     balance sheet as of December 31, 1995, and the related consolidated
     statements of income, stockholders' equity, and cash flows for the year
     then ended, and the notes and schedules thereto, prepared in accordance
     with United States generally accepted accounting principles, which
     financial statements shall be delivered as Schedule 7.9A hereto.  Such
     financial statements shall be accompanied by the audit report of a
     nationally recognized "Big Six" accounting firm.

          (b)  On or before February 28, 1996, the Company shall deliver to
     Bionova U.S. copies of the Company's audited consolidated balance sheet

     income, stockholders' equity, and cash flows for the year then ended,
     and the notes and schedules thereto, prepared in accordance with United
     States generally accepted accounting principles, which financial
     statements shall be delivered as Schedule 7.9B hereto.  Such financial
     statements shall be accompanied by the audit report of a nationally
     recognized "Big Six" accounting firm.

     7.10 Notice of Litigation.  Until the Closing, (i) Parent, Bionova
Mexico, Bionova U.S., and Sub upon learning of the same, shall promptly notify
the Company of any Proceeding which is commenced or threatened against Parent
(pertaining solely to the transactions contemplated by this Agreement),
Bionova Mexico, Bionova U.S., or the Bionova Group and (ii) the Company, upon
learning of the same, shall promptly notify Bionova U.S. of any Proceeding
which is commenced or threatened against the Company or a Company Subsidiary.

     7.11 Notification of Certain Matters.  The Company shall give prompt
notice to Bionova U.S. of the occurrence or nonoccurrence of any event the
occurrence or nonoccurrence of which would be likely to cause any
representation or warranty contained in Article III to be untrue or inaccurate
in any material respect at or prior to the Closing.  Parent, Bionova Mexico,
Bionova U.S. and Sub shall give prompt notice to the Company of the occurrence
or nonoccurrence of any event the occurrence or nonoccurrence of which would
be likely to cause any representation or warranty contained in Article IV or
Article V to be untrue or inaccurate in any material respect at or prior to
the Closing.  The delivery of any notice pursuant to this Section shall not be
deemed to (i) modify the representations or warranties hereunder of the party
delivering such notice, (ii) modify the conditions set forth in Articles IX
and X, or (iii) limit or otherwise affect the remedies available hereunder to
the party receiving such notice.

     7.12 Bionova U.S. Standstill.  Prior to the earlier of the Closing or
the termination of this Agreement, none of Parent, Bionova Mexico, the Bionova
Group, or any affiliate, director, officer, employee, or representative of
Parent, Bionova Mexico or the Bionova Group shall (i) directly or indirectly,
solicit, initiate, or conduct discussions or negotiations with any person
(other than the Company) concerning any merger, consolidation, sale of assets,
tender offer, sale of shares of capital stock, or similar transaction
involving Bionova Mexico or the Bionova Group, the securities of the Bionova
Group, or any significant assets of Bionova Mexico or the Bionova Group which
would result in a change in control of Bionova Mexico or the Bionova Group
other than as contemplated by this Agreement (each a "Bionova Acquisition
Proposal"), or (ii) disclose directly or indirectly to any person preparing to
make a Bionova Acquisition Proposal any confidential information regarding the
Bionova Group, or (iii) enter into any agreement, arrangement, understanding,
or commitment regarding any Bionova Acquisition Proposal.  Notwithstanding the
immediately preceding sentence, the Boards of Directors of Parent, Bionova
Mexico, Bionova U.S., Sub and the Bionova Group may take any of the actions
described in the preceding sentence where they have been advised by legal
counsel that taking such actions is advisable in order to fulfill their
fiduciary duties.  Bionova U.S. shall notify the Company promptly of any
Bionova Acquisition Proposal that is received after the date of this Agreement
and which a related party desires to accept and shall inform the Company if
the Board of Directors of any such party has been advised by counsel to
consider such Bionova Acquisition Proposal in order to fulfill the directors'
fiduciary duties and shall provide to the Company such information regarding
the Bionova Acquisition Proposal as the Company may reasonably request.

     7.13 Indemnification and Insurance.  To the full extent permitted by
Applicable Law, and subject to the limitations contained in Applicable Law,
all rights to indemnification now existing in favor of the directors of the
Company as provided in its Certificate of Incorporation or Bylaws in effect on
the date of this Agreement shall survive the Merger and shall continue in full
force and effect for such period as shall be permitted by Applicable Law and
shall be deemed to cover and constitute indemnification obligations of the
Surviving Corporation with respect to acts or omissions by such directors
through and including the Effective Time of the Merger (but not thereafter). 
The Surviving Corporation shall cause to be maintained for a period of three
years from the Effective Time of the Merger for the benefit of such directors,
policies of directors' and officers' liability insurance providing coverage no
less favorable than the policies currently maintained by the Company with
respect to matters occurring through and including the Effective Time of the
Merger (but not thereafter) and with aggregate limits equal to not less than
three times the aggregate limits of such currently maintained policies. 
During such three year period, Bionova U.S. will fund any "deductible" amount
specified in any such policies in the event that a claim is asserted which
implicates such policies and then only to the extent that the Surviving
Corporation is permitted to do so under such policies and Applicable Law but
is unable to do so because of its financial condition.  In the event that
Bionova U.S. or the Surviving Corporation or any of its successors and assigns
consolidates with or merges into any other person and shall not be the
continuing or surviving corporation or entity of such consolidation or merger
or transfers and conveys all or substantially all of its property and assets
to any person, then, and in each case, proper provisions shall be made so that
the successor and assigns of Bionova U.S. or the Surviving Corporation, as the
case may be, assume the obligations set forth in this Section 7.13.

     The provisions of this Section 7.13 are intended to be for the benefit
of, and shall be enforceable by, each aforementioned indemnified party, his
heirs and representatives, and may not be amended, altered or repealed without
the written consent of any such indemnified party.

     7.14 Limited Guaranty of Parent.  For a period of three years from the
Effective Time of the Merger, Parent covenants to provide when requested by
Bionova U.S. a guarantee in a form reasonably acceptable to the applicable
financial institution of Bionova U.S.'s obligations to such financial
institution pursuant to a loan or line of credit (a "Loan") if and only if
(i) Parent's maximum exposure under the guaranty is limited to $20 million,
and (ii) the documents evidencing the Loan provide that the amounts loaned to
Bionova U.S. from time to time will not exceed the sum of 80% of its and its
consolidated subsidiaries' accounts receivable from time to time plus 50% of
its and its consolidated subsidiaries' inventory from time to time and will be
secured by both such accounts and inventory.

     7.15 Governing Documents.  Prior to the Closing, Parent shall (i) cause
the governing documents of each of ABSA, Interfruver S.A. de C.V., Asesoria y
Servicios del Noreste, S.A. de C.V., Excelencia en Frutas y Verduras, S.A. de
C.V., Premier del Pacifico, S.A. de C.V. and Comercializadora Premier S.A. de
C.V. to be amended to permit the foreign ownership of such entities capital
stock to the maximum extent permitted by Mexican law, and (ii) cause the
governing documents of ABSA to be amended to reduce the quorum required to
conduct ordinary meetings of the equity owners to a simple majority of the
outstanding capital stock of ABSA and to provide that a concurring vote of a
simple majority of the present and voted capital stock of ABSA is sufficient
to validly pass resolutions at such meetings on such matters that do not
require a higher vote under Applicable Law or other governing documents.  Such
amendments shall be in the form set forth in Schedule 7.15.

     7.16 Fairness Opinion.  The Company shall use its best efforts to
obtain the fairness opinion referenced in Section 9.4 not later than the date
set forth therein.

     7.17 Bionova U.S. Organizational Documents.  Not later than the Closing
Date, Parent shall cause the certificate of incorporation and bylaws of
Bionova U.S., copies of which are included in Schedule 4.3, to be amended if
necessary under State Law, in the reasonable judgment of the parties hereto,
to accomplish the purpose, and to carry out the intent, of the Governance
Agreement.

     7.18 Notices.  To the extent that the Company and the Company
Subsidiaries, on the one hand, and Parent, Bionova Mexico, Bionova U.S., Sub
or any member of the Bionova Group, on the other hand, are required under the
terms of any agreement or arrangement, whether written or oral, to notify any
third party or to take any other action as a result of the transactions
contemplated hereby or the Ancillary Documents, they will effect any such
notice or action not later than the date specified in any such agreement or
arrangement.

                                ARTICLE XI

of itself and on behalf of Parent, Bionova Mexico and Sub, this Agreement may
be terminated and the transactions contemplated hereby abandoned at any time
prior to the Closing (notwithstanding any approval of this Agreement by the
stockholders of the Company) in the following manner:

          (a)  by mutual written consent of the Company and Bionova U.S.;
     or

          (b)  by either the Company or Bionova U.S., if the Closing shall
     not have occurred on or before July 31, 1996, unless such failure to

     terminate this Agreement pursuant to this clause (b); or

          (c)  by either the Company or Bionova U.S., if there shall be any
     statute, rule, or regulation that makes consummation of the transactions

     Entity shall have issued an order, decree, or ruling or taken any other
     action permanently restraining, enjoining, or otherwise prohibiting the
     consummation of the transactions contemplated hereby, and such order,
     decree, ruling, or other action shall have become final and

     material facts relating to the business, assets, results of operations,
     condition (financial or otherwise), or prospects of the Bionova Group
     which, in the good faith judgment of the Company, make it inadvisable
     for the Company to proceed with the consummation of the transactions
     contemplated hereby; or

          (f)  by Bionova U.S. no later than fifteen days after a Schedule
     Delivery Date for the Company if, as a result of the delivery of any

     the transactions contemplated hereby; or

          (g)  by the Company, in the event of a material breach by Parent,
     Bionova U.S., or Sub of any representation, warranty, covenant or
     agreement contained herein which is not curable or has not been cured,
     in the case of a representation or warranty, prior to the Closing or, in

     representation or warranty, prior to the Closing or, in the case of a
     covenant or agreement, within thirty days following receipt by the
     Company of written notice of such breach from Bionova U.S.; or

          (i)  by the Company, if, for the twelve month period ended
     December 31, 1995, the Earnings Before Interest and Tax (net of minority
     interests) of the entities that will constitute the Bionova Group as of
     the Closing as set forth in the financial statements of the Bionova
     Group delivered pursuant to Section 7.9(a) (Delivery of 1995 Audited
     Financial Statements) are less than $6 million; or

          (j)  by either the Company or Bionova U.S., if the Board of
     Directors of the Company shall have approved and/or recommended to the
     stockholders of the Company an Alternative Transaction (as defined in
     Section 11.3(e)). 

     11.2 Effect of Termination.  In the event of the termination of this
Agreement pursuant to Section 11.1 by the Company, on the one hand, or Bionova
U.S., on the other, written notice thereof shall forthwith be given to the

is made, and this Agreement shall become void and have no effect, except that
the agreements contained in this Section, in Sections 7.7 and 11.3, in Article
XII, and in applicable provisions of Article XIII shall survive the
termination hereof.  Nothing contained in this Section shall relieve any party
from liability for damages actually incurred as a result of any breach of this
Agreement.  No termination of this Agreement shall affect the obligations of
the parties pursuant to the Confidentiality Agreement referred to in
Section 7.1, except to the extent specified in such agreement.

     11.3 Expenses.

          (a)  Except as otherwise expressly provided in this Agreement,
     all fees and expenses, including fees and expenses of counsel, financial
     advisors, and accountants, incurred in connection with this Agreement
     and the transactions contemplated hereby shall be paid by the party
     incurring such fee or expense, whether or not the transactions
     contemplated hereby are consummated; provided, that all such fees and
     expenses incurred by any of Bionova Mexico, Bionova U.S. or Sub shall be
     paid by Parent (other than the expenses pertaining to compliance with

          (c)  Parent or Bionova U.S. shall pay the Company up to
     $1,500,000 as reimbursement for expenses of the Company actually
     incurred relating to the transactions contemplated by this Agreement
     prior to termination (including without limitation fees and expenses of
     the Company's counsel, accountants and financial advisers) upon the
     earliest to occur of the following:

               (i)  the termination of this Agreement by the Company

               (iii)     the termination of the Agreement by Bionova U.S.
          pursuant to Section 11.1(b) at a time when the Company could have
          terminated the Agreement pursuant to Section 11.1(g).

          (d)  In addition to any amounts required to be paid by the
     Company pursuant to Section 11.3(b), the Company shall pay Bionova U.S.
     (or any person designated by Bionova U.S. for such purpose) a fee equal
     to the excess of $2,000,000 over the amount paid by the Company pursuant
     to Section 11.3(b) if, within one year from the date of termination of
     this Agreement for any of the reasons set forth in Section 11.3(b), an
     Alternative Transaction occurs, the Company announces publicly its
     intention to enter into an Alternative Transaction, or the Company
     enters into an agreement contemplating an Alternative Transaction.  Such
     payment shall be made upon the earlier to occur of the events described

     or exercisable into voting capital stock) of the Company representing
     more than 15% (for purposes of Section 11.1(j)) or 35% (for purposes of
     Section 11.3(d)) of the outstanding voting power of the Company, whether
     from the Company, pursuant to a tender offer or exchange offer, or
     otherwise; (ii) a merger or other business combination involving the
     Company pursuant to which any Third Party acquires capital stock (or

     voting capital stock) of the Company representing more than 15% (for
     purposes of Section 11.1(j)) or 35% (for purposes of Section 11.3(d)) of
     the outstanding voting power of the Company or the entity surviving such
     merger or business combination; or (iii) any other transaction pursuant
     to which any Third Party acquires control of assets (including for this
     purpose the outstanding equity securities of Subsidiaries of the
     Company, and the entity surviving any merger or business combination
     including any of them) of the Company having a fair market value equal
     to more than 15% (for purposes of Section 11.1(j)) or 35% (for purposes
     of Section 11.3(d)) of the fair market value of all the assets of the
     Company immediately prior to such transaction.

     11.4 Amendment.  This Agreement may not be amended except by an
instrument in writing signed by or on behalf of all the parties hereto.

     11.5 Waiver.  Each of the Company and Bionova U.S. may (i) waive any
inaccuracies in the representations and warranties of the other contained
herein or in any document, certificate, or writing delivered pursuant hereto
or (ii) waive compliance by the other with any of the other's agreements or
fulfillment of any conditions to its own obligations contained herein.  Any
agreement on the part of a party hereto to any such waiver shall be valid only
if set forth in an instrument in writing signed by or on behalf of such party. 
No failure or delay by a party hereto in exercising any right, power, or
privilege hereunder shall operate as a waiver thereof nor shall any single or
partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power, or privilege.


                                ARTICLE XII

                               MISCELLANEOUS

     12.1 Nonsurvival of Representations, Warranties, and Agreements.  None
of the representations, warranties and agreements in this Agreement or in any
instrument delivered pursuant to this Agreement shall survive the Closing and
the Effective Time, except for the agreements contained in Article I, Article
II, Article XII, and Sections 7.1, 7.5, 7.13, 7.14, 11.3, 12.2, 12.3, 12.5,
12.6 and 12.14.

     12.2 Indemnification.

          (a)  Subject to the terms and conditions of this Section 12.2,
     Parent shall indemnify and hold harmless Bionova U.S. from and against
     any and all losses, damages, liabilities, judgments, settlements,
     penalties, costs, and expenses (including reasonable attorneys' fees and
     expenses), of any nature whatsoever (collectively, "Losses"), incurred
     by Bionova U.S. or any member of the Bionova Group, directly or
     indirectly, by reason of, relating to, or resulting from any of the
     events ("Triggering Events") described on Schedule 12.2-1 (collectively,
     "Company Claims").

          (b)  Parent shall not have any indemnification obligation
     pursuant to this Section 12.2 or otherwise in respect of this Agreement
     unless before the Claim Limitation Date it shall have received from
     Bionova U.S. written notice that a Triggering Event has occurred (a
     "Claim Notice").  The Claim Notice shall set forth with reasonable
     specificity (i) the factual basis for asserting that a Triggering Event
     has occurred and (ii) an estimate of the amount of Losses to be incurred
     as a direct or indirect result of such Triggering Event (which estimate
     shall not be conclusive of the final amount of indemnification) and an
     explanation of the calculation of such estimate, including a statement
     of any significant assumptions employed therein.  The decision to
     deliver a Claim Notice shall be in the sole discretion of the DNAP
     Independent Directors as such term is defined in the Governance
     Agreement.  The "Claim Limitation Date" shall be the first anniversary
     of the Closing Date (except for matters identified in items 1 and 4 of
     Schedule 12.2-1, in which case the Claim Limitation Date shall be the
     Final Claim Date, as defined below).

          (c)  The indemnification obligations of Parent pursuant to this
     Section 12.2 shall be subject to the following limitations and other
     provisions:

               1.   No indemnification shall be required to be made by
          Parent with respect to any Company Claims unless the aggregate
          amount of Losses incurred by Bionova U.S. and the Bionova Group
          with respect to all Company Claims, less all reductions and other
          adjustments provided for in this Section 12.2(c), exceeds
          $300,000, in which event indemnification will relate back to the
          first dollar of Loss.

               2.   Parent's indemnification obligation hereunder shall in
          no event exceed $1,500,000.

               3.   Any indemnity payments owed by Parent to Bionova U.S.
          pursuant to this Section 12.2 shall be reduced by the amount of
          the Indemnity Offset, if any, provided that Parent has delivered
          an Offset Notice to Bionova U.S. before the first anniversary of
          the Closing Date.  The "Indemnity Offset" shall be the aggregate
          Losses incurred by Bionova U.S. and the Surviving Corporation by
          reason of, relating to, or resulting from any of the events
          described on Schedule 12.2-2 ("Offset Events").  "Offset Notice"
          means a written notice setting forth with reasonable specificity
          (i) the factual basis for asserting that an Offset Event has
          occurred and (ii) an estimate of the amount of Losses to be
          incurred as a direct or indirect result of such Offset Event
          (which estimate shall not be conclusive of the final amount of
          offset) and an explanation of the calculation of such estimate,
          including a statement of any significant assumptions employed
          therein.

               4.   Any indemnity payments owed by Parent to Bionova U.S.
          pursuant to this Section 12.2 arising from Losses incurred by a
          company of the Bionova Group shall be reduced to the product of
          (x) the amount of such Losses multiplied by (y) the percentage of
          the equity of such company owned directly or indirectly by Bionova
          U.S.

               5.   Any indemnity payments owed by Parent to Bionova U.S.
          pursuant to this Section 12.2 as a result of any Company Claim
          shall be reduced to the extent of any amounts actually received by
          Bionova U.S. or any other member of the Bionova Group pursuant to
          the terms of any insurance policies or contractual indemnities
          covering such claim.  The amount of the Indemnity Offset shall
          likewise be reduced to the extent of any amounts actually received
          by Bionova U.S. or the Surviving Corporation pursuant to the terms
          of any insurance policies or contractual indemnities covering such
          matters.

               6.   Notwithstanding any other provision of this Section
          12.2, Parent will have no obligation to make any payment to
          Bionova U.S. relating to a matter described on Schedule 12.2-1
          unless, prior to the date of the 1999 annual meeting of
          shareholders of Bionova U.S. (the "Final Claim Date"), (i) a
          Governmental Entity has issued an order or assessment against a
          member of the Bionova Group with respect to that matter,
          (ii) Bionova U.S. or a member of the Bionova Group has agreed to
          make a payment in settlement of that matter, or (iii) Parent has
          become obligated to make such payment pursuant to Section 12.2(d).

                                Background

     WHEREAS, the Company, a subsidiary of the Company (the "Subsidiary"),
ELM, Bionova, S.A. de C.V. and DNA Plant Technology Corporation ("DNAP") have
entered into an Agreement and Plan of Merger, dated as of January 26, 1996
(the "Merger Agreement"), pursuant to which (i) the Subsidiary is being merged
with and into DNAP on the date of this Agreement (the "Merger"), and (ii) the
issued and outstanding shares of capital stock of DNAP (except for shares held
by DNAP in its treasury, which shares shall be cancelled, and shares as to
which appraisal rights have been perfected) are being converted in the Merger
into shares of common stock, $.01 par value, of the Company (the "Common
Stock") at various rates provided in the Merger Agreement;

     WHEREAS, the parties to this Agreement recognize the need to protect the
public shareholders (because of their status as minority shareholders) of the
Company subsequent to the Merger and intend that such shareholders as a group
be deemed third-party beneficiaries of this Agreement whose rights will be
protected by certain independent directors of the Company;

     WHEREAS, the parties to this Agreement desire to establish certain terms
and conditions concerning the corporate governance of the Company including
the composition of the board of the Company (the "Board"); and

     WHEREAS, the parties to this Agreement also desire to establish certain
terms and conditions concerning the acquisition and disposition of securities
of the Company by ELM and its affiliates;

     NOW, THEREFORE, in consideration of the foregoing and the mutual
promises and agreements contained herein, the parties hereto agree as follows:

                      ARTICLE I - BOARD OF DIRECTORS

     1.01  Independent Directors.  From and after the effective time of the
Merger ("Effective Time") and until this Agreement is terminated in accordance
with its terms, the number of directors comprising the Board shall be not less
than eleven.  Of those eleven directors, four directors shall (subject to the
adjustment pursuant to Section 1.02 hereof) be independent directors, each of
whom shall be deemed independent (each of these four directors being an
"Independent Director") if:  (i) other than acting as a director of DNAP at
any time or of the Company or a subsidiary of the Company after the date of
this Agreement, such director is not an employee or an Affiliate (as defined
below) of the Company, ELM or any Affiliate of ELM, and (ii) such director is
an "independent director" for purposes of Part III Section 6(c) of Schedule D
to the By-Laws of the National Association of Securities Dealers, Inc. 
"Affiliate" means, with respect to any person, any other person controlling,
controlled by or under direct or indirect common control with such person. 
For the purposes of this definition, "control," when used with respect to any
specified person, shall mean the power to direct the management and policies
of such person, directly or indirectly, whether through ownership of voting
securities, by contract or otherwise.  Three of the initial Independent
Directors shall be current DNAP Independent Directors (the "DNAP Independent
Directors") designated by the DNAP board of directors prior to the Merger and
one shall be designated by ELM (the "ELM Independent Director"), with the
consent of DNAP, which consent shall not be unreasonably withheld or delayed,
prior to the Merger.  Notwithstanding the foregoing and any other provision of
this Agreement, upon the occurrence of the first DNAP Independent Director to
resign or die after the date of this Agreement, the number of Company
directors shall be reduced to not less than nine.  Of those nine directors,
three directors (subject to adjustment pursuant to Section 1.02 hereof) shall
be Independent Directors.  Under such circumstances, two of such Independent
Directors shall be DNAP Independent Directors and one such Independent
Director shall be an ELM Independent Director.  The reduction from eleven to
nine directors as hereinabove provided shall not have the effect of shortening
the term of any director in office at the time of such reduction, but such
reduction will be effected in connection with the next succeeding annual
meeting of Company stockholders.

     1.02  ELM Directors.  The other seven (six in the event of a reduction
of the type contemplated in Section 1.01) directors shall be designated by ELM
and may be Affiliates or employees of either the Company or ELM, but shall not
be considered "Independent Directors" for purposes of this Agreement.  If the
Common Stock beneficially owned, directly or indirectly, by ELM and its
Affiliates is 80% or more, ELM may designate nine (seven in the event of a
reduction of the type contemplated in Section 1.01) directors, and the number
of DNAP Independent Directors shall be reduced to two.  All such adjustments
are intended to be made at the next annual meeting of the Company after a
change in stock ownership.

     1.03  Initial Nomination.  In accordance with this Agreement, ELM and
DNAP shall designate the eleven director nominees prior to the mailing of the
Proxy Statement (as defined in the Merger Agreement), to serve from the
Effective Time until the next annual meeting of stockholders of the Company.

     1.04  Continued Independent Director Representation.  Each year the
proxy statement for the Company s annual meeting as approved by the Board
(each an "Annual Proxy Statement") shall include as nominees for election to
the Board the Independent Directors who then currently sit on the Board.  If
any of the DNAP Independent Directors resigns from, or otherwise leaves, the
Board, the remaining Independent Directors shall by majority vote select a
replacement Independent Director for the departing DNAP Independent Director,
subject to the consent of ELM which shall not be unreasonably withheld or
delayed, and upon the receipt of such consent such individual shall
immediately assume the remaining term of the departing Independent Director. 
If the ELM Independent Director resigns, or otherwise leaves, the Board, ELM
shall select a replacement Independent Director for the departing ELM
Independent Director, subject to the consent of a majority of the DNAP
Independent Directors which consent shall not be unreasonably withheld or
delayed, and upon the receipt of such consent such individual shall
immediately assume the remaining term of the departing ELM Independent
Director.  To the extent permitted by the certificate of incorporation and the
bylaws of the Company, the Board shall elect each person so designated or
nominated, and shall include such individual in the next Annual Proxy
Statement as a nominee for election to the Board.  Notwithstanding the
foregoing, the Company shall not be required in the Annual Proxy Statement for
the Company's 1999 annual meeting of stockholders to include as nominees for
election as directors at such meeting any DNAP Independent Directors then in
office, which annual meeting shall be held no earlier than May 1, 1999.

     1.05  ELM Vote.  Whenever an election of the directors of the Company is
held, ELM shall vote, or cause to be voted, all shares of the Common Stock
that it directly or indirectly beneficially owns for the incumbent DNAP
Independent Directors (and any replacement Independent Director(s) nominated
by the Independent Directors).  In addition, ELM shall not vote its shares in
a manner that contravenes the terms and intentions of this Agreement.

     1.06  Removal of Independent Directors.  A DNAP Independent Director may
be removed from office only with the unanimous vote of the other DNAP
Independent Directors.  An ELM Independent Director may be removed from office
only with the consent of ELM.

     1.07  Non-Independent Directors.  Other than Robert Serenbetz whom ELM
shall cause to continue as a director so long as he remains an employee of the
Company or any of its Affiliates, ELM (subject to the requirements of
Section 1.01 and subject to the adjustment in Section 1.02 (ELM Directors))
and any nominating or proxy committee of the Company shall have the right to
designate or nominate any replacement director who is not a DNAP Independent
Director at the termination of such director s term or upon death,
resignation, retirement, disqualification, removal from office or other cause. 
To the extent permitted by the certificate of incorporation or bylaws of the
Company, the Board shall elect each person so designated or nominated.

     1.08  Committees.  Each committee which may be established by the Board
(other than a committee of Independent Directors constituted for the purposes
of making any determination under the terms of this Agreement or otherwise)
shall at all times include at least one DNAP Independent Director (in each
case designated by a majority of the Independent Directors), and no action by
any such committee shall be valid unless taken at a meeting for which adequate
notice has been duly given to or waived by the members of such committee.  Any
committee member unable to participate in person at any meeting shall be given
the opportunity to participate by telephone.  Any DNAP Independent Director
designated by the Independent Directors to serve on any committee may
designate as his or her alternate another DNAP Independent Director.

     1.09  Independent Director Approval Required for Certain Actions.  In
addition to such other approvals as may be required under applicable law, the
approval of a majority of the Independent Directors then in office shall be
required to approve any of the following:

     (a)  the sale, lease, license, transfer or other disposal of, including
any pledge or other grant of a security interest in all or a substantial
portion of the business or assets of the Company or any merger or
consolidation of any kind involving the Company in one or in a series of
transactions.  (For purposes of this clause, a "substantial portion of the
business or assets of the Company" shall mean either substantially all of the
assets that constitute the assets of DNAP as of the date of this Agreement or
a portion of the business or assets of the Company accounting for 51% of the
consolidated total assets, contribution to net income or revenues of the
Company and its subsidiaries taken as a whole, and shall include any
intellectual property that is material to the business of the Company and its
subsidiaries taken as a whole, and "material intellectual property" shall mean
any intellectual property that is required in any process resulting in or
independently results in 51% of the revenues of the Company and its
subsidiaries taken as a whole);

     (b)  any material transaction or activities (including, without
limitation, any repurchase, redemption or issuance of any capital stock or
equity including any Equity Securities of the Company) by the Company or one
of its subsidiaries with or for the benefit of ELM or an ELM Affiliate (other
than any benefit that derives as a result of its or its Affiliate's ownership
interest in the Company) other than as expressly permitted by the Ancillary
Documents (as defined in the Merger Agreement), except that any amendment to
the Ancillary Documents or any waiver by the Company of any covenant or other
provision under them or the Merger Agreement requires approval under this
Section 1.09.  For purposes of this Section 1.09(b) "material" transactions
and activities shall not include the following so long as the terms thereof
are commercially reasonable and entered on terms that are no less favorable
than could be obtained in a similar transaction with an independent third
party:  (i) a transaction or activity, or series of related transactions or
activities not involving the repurchase, redemption or issuance of any capital
stock or equity including any Equity Security, not reasonably anticipated to
result in annual expenditures or annual revenue in excess of $1,000,000 in any
of the first five years after such transaction occurs or activity begins; (ii)
any renewal on substantially the same terms of an existing agreement other
than an Ancillary Agreement or (iii) an inter-company transfer involving the
purchase or sale of goods or services available in the ordinary course from
third party providers on substantially the same terms.  "Equity Security"
shall mean any (x) voting stock of the Company (other than shares of voting
stock not having the right to vote generally in any election of directors of
the Company), (y) securities of the Company convertible into or exchangeable
for such stock, and (z) options, rights and warrants issued by the Company to
acquire such stock;

     (c)  the repurchase or redemption of any Equity Securities or other
capital stock of the Company, other than redemptions required by the terms
thereof and purchases made at fair market value in connection with any
deferred compensation plan maintained by the Company;

     (d)  the creation of any committee of the Board with power to approve
any matter that is the subject of this Agreement;

     (e)  a tender offer, directly or indirectly, by ELM for Equity
Securities of the Company, as provided in Section 2.01 (Purchase Limitation);

     (f)  the amendment or the waiver by the Company of a provision of this
Agreement, as provided in Section 6.02 to this Agreement (Amendments; No
Waivers);

     (g)  any amendment to the certificate of incorporation or bylaws of the
Company which would have a direct adverse effect on the rights or protections
provided to those holders of Common Stock other than ELM and its Affiliates
under this Agreement; or

     (h)  any attempt to effect or any action that reasonably could be
anticipated to result in the delisting or deregistering of the Company's
Common Stock from the NASDAQ National Market System or from any other national
securities exchange on which such Common Stock may then be listed.

     1.10 Indemnification and Insurance for Independent Directors.

     (a)  After the Effective Time, ELM shall cause the Company, to the full
extent permitted, but subject to the limitations of, applicable law, to
indemnify, defend and hold harmless each person who is at any time after the
date of this agreement an Independent Director (for the purposes of this
section, the "Indemnified Parties") against all losses, claims, damages,
costs, expenses, liabilities or judgments or amounts that are paid in
settlement with the approval of the Company (which approval shall not be
unreasonably withheld) of or in connection with any claim, action, suit,
proceeding or investigation based in whole or in part on  or arising in whole
or in part out of the fact that such person is or was after the Effective Time
an Independent Director ("Indemnified Liabilities") including, without
limitation, all losses, claims, damages, costs, expenses, liabilities or
judgments based in whole or in part on, or arising in whole or in part out of,
or pertaining to this Agreement or any transaction contemplated hereby.  The
Company will pay expenses in advance of the final disposition of any such
action or proceeding to each Indemnified Party to the full extent permitted by
law upon receipt of any undertaking contemplated by Section 145(e) of the
Delaware General Corporation Law ("DGCL").  Without limiting the foregoing, in
the event of any such claim, action, suit, proceeding or investigation is
brought against any Indemnified Party, (i) the Indemnified Parties may retain
counsel satisfactory to them and the Company, (ii) the Company shall pay all
reasonable fees and expenses of such counsel for the Indemnified Parties
promptly as statements therefor are received, and (iii) the Company will use
all reasonable efforts to assist in the defense of any such matter, provided
that the Company shall not be liable for any settlement or any claim effected
without such party s written consent, which consent, however, shall not be
unreasonably withheld.  Any Indemnified Party wishing to claim indemnification
under this Section 1.10, upon learning of any such claim, action, suit,
proceeding or investigation, shall promptly notify the Company (but the
failure so to notify the Company shall not relieve it from any liability which
it may have under this Section 1.10 except to the extent such failure
prejudices such party), and shall deliver to the Company the undertaking
contemplated by Section 145(e) of the DGCL.  The Indemnified Parties as a
group shall retain only one law firm to represent them with respect to each
such matter unless there is, under applicable standards of professional
conduct, a conflict on any significant issue between the positions of any two
or more Indemnified Parties.

     (b)  For a period of five years after the Effective Time, the Company
shall use its best efforts to contract and maintain in effect directors  and
officers  liability insurance covering equally all directors, including the
Independent Directors, on terms and in an amount not less than that provided
to the directors of DNAP prior to the Effective Time (which policy may take
the form of a policy covering the directors of ELM and majority owned
subsidiaries thereof).

     (c)  In the event that any of the Company or any of its successors and
assigns consolidates with or merges into any other person and shall not be the
continuing or surviving corporation or entity of such consolidation or merger
or transfers and conveys all or substantially all of its property and assets
to any person, then, and in each case, proper provisions shall be made so that
the successor and assigns of such Indemnifying Parties assume the obligations
set forth in this Section 1.10.

     (d)  The provisions of this Section 1.10 are intended to be for the
benefit of, and shall be enforceable by, each Indemnified Party, his or he
heirs and representatives, and may not be amended, altered or repealed without
the written consent of any affected Indemnified Party.
     (e)  Other than to cause the Company to carry out the terms of this
Section 1.10, ELM shall have no liability or obligation under this
Section 1.10, including, without limitation, any obligation to advance funds
to the Company for the purpose of enabling the Company to pay or satisfy any
obligations arising under this Section 1.10. 

ARTICLE II - FURTHER ACQUISITIONS OF COMPANY SECURITIES BY ELM
     
     2.01  Purchase Limitation.  Prior to the third anniversary of the date
of this Agreement, ELM and its Affiliates shall not, directly or indirectly,
purchase or otherwise acquire, or propose or offer to purchase or acquire, any
Equity Security of the Company, whether by tender offer, market purchase,
privately negotiated purchase, merger or otherwise.  In addition, except as
specifically provided in this Agreement, ELM and its Affiliates shall not
solicit any proxies or form a "group" with any third party as such term is
defined in Section 13(d) of the Securities Exchange Act of 1934, as amended
(the "1934 Act").

     2.02  "Top Up" Rights.  Notwithstanding the restrictions in Section 2.01
(Purchase Limitation), when any holder as of the Effective Time (not
affiliated with ELM) of warrants or options to purchase capital stock of DNAP
which have been assumed by the Company pursuant to Sections 2.5 and 2.6 of the
Merger Agreement exercises such warrants or options and is issued shares of
the Common Stock, ELM may make purchases in the open market or in privately
negotiated transactions of such number of shares ("Top-Up Right") required to
maintain its Voting Interest at the level held immediately prior to the
exercise of the warrants or options referred to in this sentence.  ELM's
"Voting Interest" means the percentage of votes for election of directors of
the Company generally controlled directly or indirectly by ELM.

     2.03  Subscription Right.  Notwithstanding the restrictions in
Section 2.01 (Purchase Limitation), upon any issuance (except upon the
exercise of warrants or options creating a Top-Up Right) by the Company
(except to a person who is an Affiliate of ELM), by direct sale or as a result
of a merger or otherwise, ELM has a right to purchase directly from the
Company such amount of shares required to maintain its Voting Interest at the
level held immediately before the issuance referred to in this sentence.

     2.04  Subscription Procedure.  Any offer of securities required to be
made to ELM pursuant to Section  2.03 (Subscription Right) shall be made by
notice in writing at least thirty (30) days prior to the date on which the
Company intends to issue and sell such securities (the "Subscription Notice"). 
Such Subscription Notice shall set forth (i) the approximate number and type
of securities proposed to be issued and sold to persons other than ELM and ELM
Affiliates and the material terms of such securities, (ii) the proposed price
or range of prices at which such securities are proposed to be sold and the
terms of payment, (iii) the number of securities offered to ELM in compliance
with the provisions of Section  2.03, and (iv) the proposed date of issuance
and sale of such securities.  Not later than ten (10) days after receipt of
such notice, ELM shall notify the Company in writing whether it elects to
purchase all or any portion of the securities offered to ELM pursuant to such
Subscription Notice.  If ELM elects to purchase any such securities, it shall
be obligated to do so, and the securities that it shall have so elected to
purchase shall be issued and sold to ELM by the Company at the same time and
on the same terms and conditions as the securities that are issued and sold to
third parties.  If, for any reason, the sale of securities to the third
parties is not consummated, ELM s election with regard solely to the issuance
referenced in the Subscription Notice shall lapse.

     2.05  Termination of Top-Up and Subscription Rights.  Both the Top-Up
Right pursuant to Section 2.02 ("Top-Up" Rights) and the Subscription Right
pursuant to Section 2.03 (Subscription Right) shall terminate upon the sale or
any other transfer of shares of Common Stock such that ELM in combination with
its Affiliates no longer beneficially owns more than 50% of the Common Stock
on a fully diluted basis.

     2.06  Tender Offer Exception.  Notwithstanding the restrictions in
Section 2.01 (Purchase Limitation), ELM or an ELM Affiliate may make a tender
offer for 100% of the outstanding Common Stock; provided, however, that the
majority of Independent Directors then in office make a determination that the
tender offer is fair to the holders of the Company's Common Stock other than
ELM and its Affiliates from a financial point of view.

     2.07 Acquisitions of 80.1%.  Notwithstanding the restrictions in
Section 2.01 (Purchase Limitation), ELM or an ELM Affiliate can acquire
additional shares of the outstanding Common Stock so long as their aggregate
beneficial ownership of Common Stock shall not exceed 80.1%.

ARTICLE III - RESTRICTIONS ON TRANSFER OF COMMON STOCK

     3.01  Restrictions on Transfer of Common Stock.  Until the third
anniversary of the date of this Agreement, ELM agrees that it will not sell or
otherwise transfer (for the purposes of this section, "transfer" is intended
in the broadest sense and specifically includes, without limitation, a pledge
of such shares (other than a pledge of shares to secure ordinary course
loan(s) from unaffiliated commercial lender(s) or other unaffiliated financing
source(s)) and any assignment by operation of law, but shall not include a
change-in-control of ELM) any shares of Common Stock except (i) a transfer to
any entity that is directly or indirectly 51% or more owned and controlled by
ELM, provided that such entity agrees in writing to assume all of ELM s
obligations under this Agreement and performs such obligations, (ii) if it
shall have become illegal for ELM to own its shares of Common Stock directly
or indirectly or exercise fully its rights of ownership with respect to its
shares of Common Stock, ELM may sell such shares as applicable law requires,
(iii) pursuant to an unsolicited tender offer by a non-Affiliate of ELM, (iv)
any sale or other transfer of Common Stock by ELM or an Affiliate of ELM which
results in ELM together with its Affiliates beneficially owning less than 51%
of the outstanding Common Stock (on a fully diluted basis) and all holders of
Common Stock (other than ELM and its Affiliates) are given the opportunity to
sell all of their Common Stock in the transaction on substantially the same
terms per share as ELM (provided, that such holders have the opportunity to
receive all of their consideration in cash), and (v) any sale so long as,
after giving effect to such sale, ELM and its Affiliates shall beneficially
own 51% or more of the outstanding Common Stock on a fully diluted basis.


ARTICLE IV - REGISTRATION RIGHTS

     4.01  Registration.  (a)  The Company agrees that, at any time after the
third anniversary of the date of this Agreement (or such earlier date as it
shall have become illegal for ELM to own Common Stock directly or indirectly
or to exercise fully all rights of ownership with respect to its shares) and
until the tenth anniversary of the date of this Agreement, upon the request of
ELM, the Company will file a registration statement (a "Registration
Statement") under the 1933 Act as to the number of shares specified in such
request (the "Registered Shares"); provided that, subject to Section 4.04 of
this Agreement (Additional Conditions), the Company shall not be required to
file more than two Registration Statements that become effective and remain
effective for the period referred to in Section 4.01(b).

     (b)  The Company agrees to use its best efforts (i) to have any
registration of the Registered Shares declared effective as promptly as
practicable after the filing thereof, and (ii) to keep such registration
statement effective for a period (up to three months) sufficient to complete
the distribution of the Registered Shares.  The Company further agrees to
supplement or make amendments to the Registration Statement, if required (w)
to respond to the comments of the Securities and Exchange Commission, (x)
by the registration form utilized by the Company for such registration or by
the instructions applicable to such registration form, (y) by the 1933 Act or
the rules and regulations thereunder, or (z) by ELM (or any underwriter for
ELM) with respect to information concerning ELM or such underwriter or the
plan of distribution to be utilized with respect to the Registered Shares. 
The Company agrees to furnish to ELM copies of any such supplement or
amendment prior to its being used or filed with the Securities and Exchange
Commission (the "SEC").

     4.02  Registration Procedures.  Subject to the provisions of
Section 4.01 of this Agreement (Registration) in connection with the
registration of shares hereunder, the Company will as expeditiously as
possible:

     (a)  furnish to ELM, prior to filing of a Registration Statement,
copies of such Registration Statement as is proposed to be filed, and
thereafter such number of copies of such Registration Statement, each
amendment and supplement thereto (in each case including all exhibits
thereto), the prospectus included in such Registration Statement (including
each preliminary thereto), the prospectus included in such Registration
Statement (including each preliminary prospectus) and such other documents in
such quantities as ELM may reasonably request from time to time in order to
facilitate the disposition of the Registered Shares:

     (b)  use all reasonable efforts to register or qualify the Registered
Shares under such other securities or Blue Sky laws of such jurisdiction as
ELM reasonably requests and of any and all other acts and things as may be
reasonably necessary or advisable to enable ELM to consummate the disposition
in such jurisdictions of the Shares owned by ELM; provided that the Company
will not be required to qualify but for this subsection (b), (ii) subject
itself to taxation in any such jurisdiction, or (iii) consent to general
service of process in any such jurisdiction;

     (c)  use all reasonable efforts to cause the Registered Shares to be
registered with or approved by such other governmental agencies or authorities
as may be necessary by virtue of the business and operations of the Company to
enable ELM to consummate the disposition of such Shares;

     (d)  notify ELM, at any time when a prospectus relating thereto is
required to be delivered under the 1933 Act, of the happening of any event as
a result of which the prospectus included in such Registration Statement or
amendment contains an untrue statement of a material fact or omits to state
any material fact required to be stated therein or necessary to make the
statements therein not misleading, and the Company will prepare a supplement
or amendment to such prospectus so that, as thereafter delivered to the
purchasers of the Registered Shares, such prospectus will not contain an
untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary to make the statements therein not
misleading;

     (e)  enter into customary agreements (including an underwriting
agreement in customary form) and take such other actions as are reasonably
required in order to expedite or facilitate the disposition of the Registered
Shares;

     (f)  make available for inspection by ELM, any underwriter participating
in any disposition pursuant to such registration, and any attorney, accountant
or other agent retained by any ELM or any such underwriter (collectively, the
"Inspectors"), all financial and other records, pertinent corporate documents
and properties of the Company (collectively, the "Records") as shall be
reasonably necessary to enable them to exercise their due diligence
responsibility, and cause the officers, directors and employees of the Company
to supply all information reasonably requested by any such Inspector in
connection with such registration; provided that (i) records and information
obtained hereunder shall be used by such persons only to exercise their due
diligence responsibility, and (ii) records or information which the Company
determines, in good faith, to be confidential shall not be disclosed by the
Inspectors unless (x) the disclosure of such Records or information is
necessary to avoid or correct a misstatement or omission in the Registration
Statement, or (y) the release of such Records or information is ordered
pursuant to a subpoena or other order from a court or governmental authority
of competent jurisdiction.  ELM shall use reasonable efforts, prior to any
such disclosure, to inform the Company that such disclosure is necessary to
avoid or correct a misstatement or omission in the Registration Statement. 
ELM further agrees that it will, upon learning that disclosure of such Records
or information is sought in a court of governmental authority, give notice to
the Company and allow the Company, at the expense of the Company, to undertake
appropriate action to prevent disclosure of the Records or information deemed
confidential;

     (g)  use all reasonable efforts to obtain a comfort letter from the
independent public accountants for the Company in customary form and covering
such matters of the type customarily covered by comfort letters as ELM
reasonably requests;

     (h)  otherwise use all reasonable efforts to comply with all applicable
rules and regulations of the SEC, and make generally available to its security
holders, as soon as reasonably practicable, an earnings statement covering a
period of twelve months, beginning within three months after the effective
date of the registration, which earnings statement shall satisfy the
provisions of Section 11(a) of the 1933 Act and Rule 158 thereunder; and

     (i)  use all reasonable efforts to cause all Registered Shares to be
listed on each securities exchange on which similar securities issued by the
Company are listed.

     4.03  Conditions to Offerings.  The obligations of the Company to take
the actions contemplated by Section 4.01 (Registration) with respect to an
offering of Shares shall be subject to the following conditions:

     (i)  The Registered Shares shall constitute at least 10% of the
outstanding Common Stock.  If Registered Shares are to be distributed in an
underwritten firm commitment offering, ELM shall have the right to select the
investment banker or bankers and lead manager or managers to administer the
offering and its or their counsel; provided that such lead manager or managers
and such counsel must be reasonably satisfactory to the Company.

     (ii)  There shall not have been an offering registered pursuant to
Section 4.01 (Registration) within the immediately preceding twelve months and
if such earlier offering was completed or is continuing.

     (iii)  ELM shall conform to all applicable requirements of the 1933 Act
and the 1934 Act with respect to the offering and sale of securities and
advise each underwriter, broker or dealer through which any of the Registered
Shares are offered that the Registered Shares are part of a distribution that
is subject to the prospectus delivery requirements of the 1933 Act.

     The Company may require ELM to furnish to the Company such information
regarding ELM or the distribution of the Registered Shares as the Company may
from time to time reasonably request in writing, in each case only as required
by the 1933 Act or the rules and regulations thereunder or under state
securities or Blue Sky laws.

     ELM agrees that, upon receipt of any notice from the Company of the
happening of any event of the kind described in Section 4.02(d) hereof, such
holder will forthwith discontinue disposition of Registered Shares pursuant to
the registration covering such Shares until ELM's receipt of the copies of the
supplemented or amended prospectus contemplated by Section 4.02(d) hereof.

     4.04  Additional Conditions.   The Company's obligations pursuant to
Section 4.01 (Registration) shall be suspended if (i) the fulfillment of such
obligations would require the Company to make a disclosure that would, in the
reasonable good faith judgment of the Board, be detrimental to the Company
because it is premature, (ii) the Company has filed a registration statement
with respect to securities to be distributed in an underwritten public
offering and it is advised by its lead or managing underwriter that an
offering by ELM of the Registered Shares would materially adversely affect the
distribution of such equity securities, or (iii) the fulfillment of such
obligations would require the Company to prepare audited financial statements
not required to be prepared for the Company to comply with its obligations
under the 1934 Act as of any date not coincident with the last day of any
fiscal year of the Company.  Such obligations shall be reinstated (x) in the
case of clause (i) above, upon the making of such disclosure by the Company
(or, if earlier, when such disclosure would either no longer be necessary for
the fulfillment of such obligations or no longer be detrimental, (y) in the
case of clause (ii) above, upon the conclusion of any period during which the
Company would not, pursuant to the terms of its underwriting arrangements, be
permitted to sell the Registered Securities for its own account, and (z) in
the case of clause (iii) above, as soon as it would no longer be necessary to
prepare such financial statements to comply with the 1933 Act.  The period
during which ELM is required to sell its shares pursuant to Section 4.05
(Registration Expenses) shall be tolled for the duration of any suspension
pursuant to this paragraph.

     4.05  Registration Expenses.  All expenses incident to the performance
of or compliance with this Article IV by the Company, including, without
limitation, all fees and expenses of compliance with securities or Blue Sky
laws (including reasonable fees and disbursements of counsel in connection
with Blue Sky qualifications of the Registered Shares), rating agency fees,
printing expenses, messenger and delivery expenses, internal expenses
(including, without limitation, all salaries and expenses of its officers and
employees performing legal or accounting duties), the fees and expenses
incurred in connection with the listing of the securities to be registered on
each securities exchange on which similar securities issued by the Company are
then listed, fees and disbursements of counsel for the Company and its
independent certified public accounts (including the expenses of any comfort
letters required by or incident to such performance), securities acts
liability insurance (if the Company elects to obtain such insurance), the
reasonable fees and expenses of any special experts retained by the Company in
connection with such registration and the fees and expenses of other persons
retained by the Company (all such expenses being herein called "Registration
Expenses"), will be borne by the Company.  The Company will not have any
responsibility for any registration or filing fees payable under any federal
or state securities or Blue Sky laws or for any of the expenses of the holders
of Registrable Securities incurred in connection with any registration
hereunder including, without limitation, underwriting fees, discounts and
commissions and transfer taxes, if any, attributable to the sale of
Registrable Securities, counsel fees of such holders and travel costs.

     4.06  Indemnification Contribution.

     (a)  Indemnification by the Company.  The Company agrees to indemnify,
to the fullest extent permitted by law, ELM, its directors and officers and
each person who controls ELM (within the meaning of either the 1933 Act or the
1934 Act) against any and all losses, claims, damages, liabilities and
expenses (including attorneys' fees) caused by any untrue or alleged untrue
statement of material fact contained in any Registration Statement, prospectus
or preliminary prospectus (each as amended and or supplemented, if the Company
shall have furnished any amendments or supplements thereto), or any omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein (in the case of a
prospectus, in the light of the circumstances, under which they were made) not
misleading, provided that the Company shall not be required to indemnify ELM
or its officers, directors or controlling persons for any losses, claims,
damages, liabilities or expenses resulting from any such untrue statement or
omission if such untrue statement or omission is made in reliance on and
conformity with any information with respect to such ELM or such other parties
furnished to the Company by ELM or such other parties expressly for use
therein.  In connection with an underwritten offering, the Company will
indemnify each underwriter thereof, the officers and directors of such
underwriter, and each person who controls such underwriter (within the meaning
of either the 1933 Act or 1934 Act) to the same extent as provided above with
respect to the indemnification of ELM.

     (b)  Indemnification by ELM.  In connection with any registration in
which ELM is participating, ELM will furnish to the Company in writing such
information and affidavits with respect to ELM as the Company reasonably
requests for use in connection with any such registration, prospectus, or
preliminary prospectus and agrees to indemnify the Company, its directors, its
officers who sign the Registration Statement and each person, if any, who
controls the Company (within the meaning of either the 1933 Act or the 1934
Act) to the same extent as the foregoing indemnity from the Company to such
holder, but only with respect to information relating to such holder furnished
to the Company in writing by ELM expressly for use in the Registration
Statement, the prospectus, any amendment or supplement thereto, or any
preliminary prospectus.

     (c)  Conduct of Indemnification Proceedings.  In case any proceeding
(including any governmental investigation) shall be instituted involving any
person in respect of which indemnity may be sought pursuant to Section 4.07(a)
or Section 4.07(b), such person (hereinafter called the indemnified party) in
writing and the indemnifying party, upon request of the indemnified party,
shall retain counsel reasonably satisfactory to the indemnified party to
represent the indemnified party and any others the indemnifying party may
designate in such proceeding and shall pay the fees and disbursements of such
counsel related to such proceeding.  In any such proceeding, any indemnified
party shall have the right to retain its own counsel, but the fees and
expenses of such counsel shall be at the expense of such indemnified party
unless (i) the indemnifying party and the indemnified party shall have
mutually agreed to the retention of such counsel, or (ii) the named parties to
any such proceeding (including any impleaded parties) include both the
indemnifying party and the indemnified party and the indemnified party shall
have been advised by counsel that representation of both parties by the same
counsel would be inappropriate due to actual or potential differing interests
between them.  It is understood that the indemnifying party shall not, in
connection with any proceeding or related proceedings in the same
jurisdiction, be liable for the fees and expenses of more than one separate
firm (in addition to any local counsel) for all such indemnified parties, and
that all such fees and expenses shall be reimbursed as they are incurred.  In
the case of any such separate firm for the indemnified parties, such firm
shall be designated in writing by the indemnified parties.  The indemnifying
party shall not be liable for any settlement of any proceeding effected
without its written consent, but if settled with such consent or if there be a
final judgment for the plaintiff, the indemnifying party agrees to indemnify
the indemnified party from and against any loss or liability by reason of such
settlement or judgment.  Notwithstanding the foregoing sentence, if at any
time an indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for fees and expenses of counsel as
contemplated by the third sentence of this Section 4.07(c), the indemnifying
party agrees that it shall be liable for any settlement of any proceeding
affected without its written consent if (i) such settlement is entered into
more than 30 days after receipt by such indemnifying party of the aforesaid
request, and (ii) such indemnifying party shall not have reimbursed the
indemnified party in accordance with such request or reasonably objected in
writing, on the basis of the standards set forth herein, to the propriety of
such reimbursement prior to the date of such settlement.  No indemnifying
party shall, without the prior written consent of the indemnified party,
effect any settlement of any pending or threatened proceeding in respect of
which any indemnified party is or could have been a party and indemnity could
have been sought hereunder by such indemnified party, unless such settlement
includes an unconditional release of such indemnified party from all liability
on claims that are the subject matter of such proceeding.

     (d)  Contribution.  If the indemnification provided for in this
Section 4.07 from the indemnifying party is unavailable to an indemnified
party hereunder in respect of any losses, claims, damages, liabilities or
expenses referred to in this Section 4.07,  then the indemnifying party, in
lieu of indemnifying such indemnified party, shall contribute to the amount
paid or payable by such indemnified party as a result of such losses, claims,
damages, liabilities or expenses in such proportion as is appropriate to
reflect the relative fault of the indemnifying party and indemnified parties
in connection with the actions which resulted in such losses, claims, damages,
liabilities or expenses, as well as any other relevant equitable
considerations.  The relative fault of such indemnifying party and indemnified
parties shall be determined by reference to, among other things, whether any
action in question, including any untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact, has
been made by, or relates to information supplied by, such indemnifying party
or indemnified parties, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action.  The amount
paid or payable by a party as a result of the losses, claims, damages,
liabilities and expenses referred to above shall be deemed to include, subject
to the limitations set forth in Section 4.07(c), any legal or other fees or
expenses reasonably incurred by such party in connection with any
investigation or proceeding.

     The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 4.07(d) were determined by pro rata
allocation or by any other method of allocation which does not take into
account the equitable considerations referred to in the immediately preceding
paragraph.  No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution
from any person who was not guilty of such fraudulent misrepresentation.

     If indemnification is available under this Section 4.07, the
indemnifying parties shall indemnify each indemnified party to the full extent
provided in Section Section 4.06(a) and (b) without regard to the relative
fault of said indemnifying party or indemnified party or any other equitable
consideration provided for in this Section 4.06(d).

     4.07  Rule 144.  The Company covenants that it will file the reports
required to be filed by it under the 1933 Act and the 1934 Act and the rules
and regulations adopted by the SEC thereunder, and it will take such further
action as ELM may reasonably request, all to the extent required from time to
time to enable ELM to sell Shares without registration under the 1933 Act
within the limitation of the exemptions provided by (i) Rule 144 under the
1933 Act, as such Rule may be amended from time to time, or (ii) any similar
rule or regulation hereafter adopted by the SEC.  Upon the request of ELM, the
Company will deliver to ELM a written statement as to whether it has complied
with such requirements.

     4.08  No Inconsistent Agreements.  The Company will not hereafter enter
into any agreement with respect to its securities which is inconsistent with
the rights granted to ELM in this Agreement.

     4.09  Determination by Independent Directors.  Any determination
required to be made by the Company under this Article IV shall be made by a
majority of the Independent Directors then in office.

assignment in substantially the same form as Schedule 1, assigning Lender's
interest in the Patents back to Borrower, along with such other documentation

of the Loan Documents to which it is a party, the performance of its

                                 ARTICLE V

                   Covenants and Agreements of Borrower

     To conform with the terms and conditions under which Lender is willing
to have credit outstanding to Borrower, and to induce Lender to enter into
this Agreement and make the Loan, Borrower warrants, covenants and agrees as
follows until all of the Loan Indebtedness has been paid in full:

     5.01  Use of Proceeds.  Borrower shall use the proceeds of this Loan
Agreement solely for purposes of paying operating costs of the businesses of
Borrower and other general corporate purposes (including payment of costs
incurred in relation to the Merger Agreement and the Ancillary Documents (as
defined therein)), but not for any purposes prohibited by this Article V.  In
no event shall the proceeds of any Advance be used directly or indirectly for
personal, family, or household purposes.

     5.02  Costs and Expenses.  All reasonable costs and expenses associated
with collection under this Loan Agreement, including, without limitation, (a)
all fees for filing or recording any documents related to consummation of the
transactions contemplated by this Loan Agreement, (b) all reasonable fees and
expenses of counsel to Lender related to collection under this Loan Agreement,
and (c) all other reasonable costs and expenses payable to third parties
incurred by Lender in connection with the collection under this Loan
Agreement, including in connection with the defense of the Loan Documents or
the defense of Lender's exercise of its rights thereunder shall be added to
and included as Loan Indebtedness payable by Borrower to Lender in accordance
with this Loan Agreement.

     5.03  Collateral Value Deficiencies.  If at any time not earlier than
365 days after July 1, 1996 and not later than 180 days prior to the scheduled
termination date of this Loan Agreement, Lender has received an opinion from
any of the qualified professionals listed in Schedule 6 to this Loan Agreement
or such other professional as may be mutually agreed from time to time by the
parties (a "Qualified Professional") that a Collateral Value Deficiency
exists, Lender may notify Borrower of such Collateral Value Deficiency in
writing, which shall include the amount of such Collateral Value Deficiency;
provided, that no Collateral Value Deficiency Notice shall be delivered
earlier than 180 days following a prior Collateral Value Deficiency Notice
Date.  Within 30 days from and after the Collateral Value Deficiency
Notification Date, Borrower shall, at its election, take one of the following
actions:

          (i)  demonstrate to Lender's satisfaction that no such Collateral
Value Deficiency exists; provided that the delivery to Lender of a written
opinion from a Qualified Professional that no Collateral Value Deficiency
exists shall be deemed to have satisfied Lender.  Such opinion of value may
assume that additional security is made available to Lender as provided in
Section 5.03(ii) below provided that such security is so provided to Lender;

          (ii)  execute and deliver to Lender additional security which may
include, without limitation, letters of credit, guaranties and supplemental or
additional documents, in each case in form and substance reasonably
satisfactory to Lender and its counsel, securing repayment of the Loan
Indebtedness, covering property owned by Borrower not currently covered by any
Loan Document and which property is of a type and nature, and having a value
(determined by Lender and its advisors using customary standards for lending)
satisfactory to Lender; provided, however, that Borrower shall not be required
to provide an item of additional collateral if the provision of such would
cause Borrower, in the reasonable opinion of Borrower's counsel, to materially
breach any agreement between Borrower and an unrelated third party; or

          (iii)  make a payment to Lender with respect to the Loan
Indebtedness in an amount sufficient to eliminate such Collateral Value
Deficiency.

     Borrower's obligations to cure a Collateral Value Deficiency shall be
limited to those assets (other than cash and marketable securities) available
to Borrower; provided, however, if a Collateral Value Deficiency Notice has
been sent and the Collateral Value is determined to be less than the Loan
Indebtedness, then cash and marketable securities shall be considered
available assets to the extent they exceed the amount of $4,400,000.

     5.04  Additional Documents.  Borrower shall execute and deliver to
Lender, from time to time as requested by Lender, such other documents as
shall reasonably be necessary to provide the rights and remedies to Lender
granted or provided for by the Loan Documents.

     5.05  Inspection of Books and Records.  Borrower shall permit Lender or
its representatives, including independent accountants and agents, at all
reasonable times to examine and copy the books and records of Borrower
pertaining to the Loan. 

     5.06  Defense of Actions.  Borrower shall retain all rights to commence,
appear in, or defend or make decisions concerning any action or proceeding or
prosecution (including any proceeding in the United States Patent and
Trademark Office) purporting to affect, the Patents or the respective rights
and obligations of Lender and Borrower with respect thereto pursuant to any
Loan Document; provided, however, if Lender requests that Borrower take any
action regarding the matters set forth in this Section 5.06 and Borrower
refuses or fails to take such action on a timely basis, then, prior to the
repayment of the Loan Indebtedness, Lender may (but shall not be obligated to)
commence, appear in, or defend any action or proceeding (including any
proceeding in the United States Patent and Trademark Office) purporting to
affect the Patents or the respective rights and obligations of Lender and
Borrower with respect thereto pursuant to any Loan Document.  In the event
Borrower refuses or fails to take action on a timely basis reasonably
requested by Lender, then Lender shall, at its sole option, control any such
action or proceeding and Borrower agrees to appear as a party therein if
requested by Lender, and to cooperate with Lender in the conduct of such
action or proceeding whether or not it is a party.  Lender may (but shall not
be obligated to) pay all necessary expenses, including reasonable attorneys'
fees and expenses incurred in connection with such proceedings or actions,
which shall be added to and included as Loan Indebtedness payable by Borrower
to Lender in accordance with this Loan Agreement.  Any recovery obtained by
either party in enforcing the Patents will be applied first to the expenses
incurred in obtaining such recovery and then to the Loan Indebtedness.

     5.07  Prohibition on Assignment.  Borrower shall not assign or encumber
any interest of Borrower under this Loan Agreement without the prior written
consent of Lender.

     5.08  Financial Statements.  Within three business days of their filing

relating to, or supporting, such filings or that otherwise relate to
Borrower's ability to repay the Loan Indebtedness that are reasonably
requested by Lender within thirty days of such request.
  
     5.09  Notification of Adverse Changes.  Borrower shall promptly notify
Lender of the occurrence of any event or condition which, if not remedied,
would result in a material, adverse change to the financial condition of
Borrower and its subsidiaries taken as a whole or would materially and
adversely affect the value of the Patents or any portion thereof.

     5.10  Limitation on Dividends and Redemptions.  Without the prior
written consent of Lender, Borrower will not declare or pay any dividends on,
or make any other distribution in respect of, any class of its capital stock
or its other equity interests (whether such stock or interests are now or
hereafter issued, outstanding or created) while any part of the Loan
Indebtedness is unpaid.  Without the written consent of Lender, Borrower will
not directly or indirectly make any capital contribution to or purchase,
redeem, acquire or retire any shares of its capital stock or its other equity
interests (whether such stock or interests are now or hereafter issued,
outstanding or created), or cause or permit any reduction or retirement of
such capital stock or such other equity interests.

     5.11  Limitation on Sales of Property.  Without the written consent of

                 hereunder, not to exceed $25,000 in any single

Indebtedness under provisions (vi) or (viii) of this Section 5.15 if Borrower
has received a Notice of Collateral Value Deficiency and such Collateral Value
Deficiency continues to exist; and provided further, however, that the renewal
of existing Indebtedness in the amount then outstanding shall not constitute
the incurrence of additional Indebtedness under this provision.

subsidiaries will engage in any transaction with or pay any management or
other fees or compensation to any of its affiliates except transactions in the

called "liabilities and costs") which to any extent (in whole or in part) may
be imposed on, incurred by, or asserted against Lender growing out of,
resulting from or in any way associated with any of the Collateral, the Loan
Documents, or the transactions and events (including the enforcement or
defense thereof) at any time associated therewith or contemplated therein
(including any violation or noncompliance with any environmental or other

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND
COSTS ARE IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY
NEGLIGENT ACT OR OMISSION OF ANY KIND BY LENDER, provided only that Lender
shall be not entitled under this section to receive indemnification for that
portion, if any, of any liabilities and costs which is proximately caused by
its own individual gross negligence or willful misconduct, as determined by a
final judgment.  If any person (including Borrower or any of its affiliates)
ever alleges such gross negligence or willful misconduct by Lender, the

demand, subject to later adjustment or reimbursement, until such time as a
court of competent jurisdiction enters a final judgment as to the extent and
effect of the alleged gross negligence or willful misconduct.  As used in this

set forth in this Article V, in the event that Borrower is permitted under
Section 6.2 of the Merger Agreement to take or fail to take any action, it
shall also be permitted to take or fail to take such action hereunder.

                                ARTICLE VI

Agreement to require Lender to convey an assignment of Lender's interest in

no obligation to convey any interest in the Patents back to Borrower.  In the
event of such termination of Borrower's assignment rights, Lender shall be
entitled to (i) dispose of the Patents (subject to such retained rights, if
any, in the Patents that may then be granted to Borrower by Lender under the
Sole Patent License) in a commercially reasonable manner (including, without
limitation, a sale in which Lender shall be entitled to "credit bid" the Loan
Indebtedness and, if it is the highest bidder for the Patents, retain title to
the Patents) and the proceeds therefrom shall be applied to the Loan
Indebtedness, or (ii) if Lender can demonstrate with a written opinion of a
Qualified Professional that (a) the value of the Patents is equal to or less
than the amount of the Loan Indebtedness or (b) the value of the Patents
exceeds the Loan Indebtedness by an amount which Lender agrees to pay to
Borrower, retain the Patents in full and complete satisfaction of the Loan
Indebtedness by giving Borrower thirty days prior written notice of such
election.  

    6.03  No Waiver or Exhaustion.  All of Lender's rights and remedies with
respect to any Loan Document or relating to the Patents shall be cumulative
and may be exercised singularly or concurrently.  No waiver by Lender of any
of its rights or remedies hereunder, in the other Loan Documents, or
otherwise, shall be considered a waiver of any other or subsequent right or
remedy of Lender; no delay or omission in the exercise or enforcement by
Lender of any rights or remedies shall ever be construed as a waiver of any
right or remedy of Lender; and, no exercise or enforcement of any such rights
or remedies shall ever be held to exhaust any right or remedy of Lender.

                                ARTICLE VII

                       General Terms and Conditions

    7.01  Notices.  All notices, demands, requests, and other communications
required or permitted hereunder shall be in writing and shall be deemed to
have been given when received by Borrower or Lender, as the case may be, at
the respective addresses set forth on the first page of this Loan Agreement,
or such other address as Borrower or Lender may from time to time designate by
written notice to the other as herein required.

    7.02  Modifications.  No provision of this Loan Agreement or the other
Loan Documents may be modified, waived, or terminated except by instrument in
writing executed by the party against whom a modification, waiver, or
termination is sought to be enforced.

    7.03  Severability.  In case any of the provisions of this Loan
Agreement shall for any reason be held to be invalid, illegal, or
unenforceable, such invalidity, illegality, or unenforceability shall not
affect any other provision hereof, and this Loan Agreement shall be construed
as if such invalid, illegal, or unenforceable provision had never been
contained herein.

    7.04  Election of Remedies.  Lender shall have all of the rights and
remedies granted in the Loan Documents and available at law or in equity, and
these same rights and remedies shall be cumulative and may be pursued
separately, successively, or concurrently against Borrower, or the Patents at
the sole discretion of Lender.  The exercise or failure to exercise any of the
same shall not constitute a waiver or release thereof or of any other right or
remedy, and the same shall be nonexclusive.

    7.05  Form and Substance.  All documents, certificates, and other items
required under this Loan Agreement to be executed and/or delivered to Lender
shall be in form and substance reasonably satisfactory to Lender.

    7.06  Controlling Agreement.  All agreements between Borrower and
Lender, whether now existing or hereafter arising and whether written or oral,
are hereby limited so that in no event shall the interest paid, or agreed to
be paid, to Lender for the use, forbearance, or detention of the money to be
loaned pursuant to this Loan Agreement, or for the performance or payment of
any covenant or obligation contained herein, exceed the maximum amount
permissible under applicable law.  If from any circumstances whatsoever
fulfillment of any provision hereof or of any other document evidencing,
securing, or pertaining to the Loan, at any time performance of such provision
shall be due, shall involve transcending the limit of validity prescribed by
law, then ipso facto, the obligation to be fulfilled shall be reduced to the
limit of such validity; and if from any such circumstances Lender shall ever
receive anything of value deemed interest under applicable law which would
exceed interest at the highest lawful rate, the excessive interest shall be
applied to the reduction of the principal amount owing under the Note and not
to the payment of interest, or if the excessive interest exceeds the unpaid
balance of principal of the Note, such excess shall be refunded to Borrower. 
All sums paid or agreed to be paid to Lender for the use, forbearance, or
detention of the indebtedness evidenced hereby shall, to the extent permitted
by applicable law, be amortized, prorated, allocated, and spread throughout
the full term of such indebtedness until payment in full in such manner as is
permitted by law.  This paragraph shall control all agreements between
Borrower and Lender.

    7.07  No Third Party Beneficiary.  This Loan Agreement is for the sole
benefit of Lender and Borrower and is not for the benefit of any third party.

    7.08  Number and Gender.  Whenever used herein, the singular number
shall include the plural and the singular, and the use of any gender shall be
applicable to all genders.

                              PROMISSORY NOTE


$10,000,000.00                 Dallas, Texas               January 26, 1996


     FOR VALUE RECEIVED, the undersigned, DNA PLANT TECHNOLOGY CORPORATION, a
Delaware corporation (herein called the "Borrower"), hereby promises to pay to
the order of BIONOVA U.S. INC., a Delaware corporation (herein called the
"Lender", which term shall also include any subsequent transferee of this Note),
the principal sum of Ten Million and No/100 Dollars U.S. ($10,000,000.00), with
interest on the unpaid balance thereof from the date of advancement thereof
pursuant to the Loan Agreement (as hereinafter defined) until maturity at the
rate or rates hereinafter provided, both principal and interest payable as
hereinafter provided funds in lawful money of the United States of America at
1700 Pacific Avenue, Suite 3300 (attention: JAR), Dallas, Texas 75201, or at 
such other place as from time to time may be designated in writing by the holder
of this Note.

     Borrower promises to pay interest on the principal amount hereof from time
to time outstanding, from January 29, 1996, at the rate of 10.25% per annum (the
"Loan Rate"), compounded annually.  Interest shall accrue but not be payable
until the unpaid principal amount hereof or any portion hereof which is prepaid
is due and payable in full to Lender.  Such interest shall be payable in like
coin or currency as the principal amount hereof.  Anything to the contrary
notwithstanding, if at any time the Loan Rate exceeds the Maximum Rate (as
hereinafter defined), the Loan Rate shall be limited to the Maximum Rate, but 
any subsequent reductions in the Loan Rate shall not reduce the rate of interest
which the unpaid principal balance of this Note bears below the Maximum Rate
until such time as the total amount of interest accrued on this Note equals the
amount of interest that would have accrued under this Note if the Loan Rate had
at all times been in effect.  All past due principal and/or interest hereunder
shall bear interest from maturity at the Maximum Rate.  All interest 
calculations hereunder shall be made on the basis of a 365 day year and the 
actual number of days elapsed.  Any payment made by Borrower to Lender
hereunder be credited first to accrued and unpaid expenses hereunder or under 
the Loan Agreement, next to accrued and unpaid interest hereunder, and last to 
unpaid principal hereunder.

     Unless sooner demanded by Lender as permitted under the Loan Agreement, the
entire unpaid principal amount hereof, together with interest accrued hereon,
shall, without notice, be due and payable in full to Lender in immediately
available funds on the earlier of (i) January 26, 1999, (ii) if either party has
elected to terminate that certain Merger Agreement of even date herewith among
Lender, Borrower and certain other parties noted therein (as such agreement may
be amended from time to time,the "Merger Agreement") pursuant to Section 11.1(j)
thereof, then on the date on which any form of "Alternative Transaction"(as that
term is defined in the Merger Agreement) is actually consummated by Borrower,and
(iii) if the Merger Agreement terminates for any other reason, then on the date
on which an Alternative Transaction involving more than 35% of the voting power,
directly or indirectly through options, warrants or convertible securities, of
Borrower or any party surviving such Alternative Transaction or more than 35% of
the fair market value of the assets of Borrower) is actually consummated by
Borrower.  Upon the occurrence of an "Event of Default" under the Loan 
Agreement, Lender may elect to declare and may at any time declare the entire 
unpaid principal amount hereof, together with interest accrued hereon, to be 
immediately due and payable.  

     As provided in the Loan Agreement, this Note is secured by an Assignment
of Patents of even date herewith evidencing a transfer of an interest in certain
patent rights by Borrower to Lender as described therein.

     This Note may be prepaid in whole or in part at any time without bonus or
penalty, subject to the terms and conditions of the Loan Agreement.

     This Note (a) is issued and delivered under that certain Loan Agreement of
even date herewith between Borrower and Lender (herein, as from time to time
supplemented, amended or restated, called the "Loan Agreement"), and is the Note
as defined therein, and (b) is subject to the terms and provisions of the Loan
Agreement, which contains provisions for payments and prepayments hereunder and
acceleration of the maturity hereof upon the happening of certain stated events.

     It is the intent of Borrower and Lender in the execution of this Note and
all other instruments now or hereafter executed in connection with this Note to
contract in strict compliance with applicable usury law. In furtherance thereof,
Borrower and Lender stipulate and agree that none of the terms and provisions
contained in this Note, or in any other instrument executed in connection
herewith, shall ever be construed to create a contract to pay for the use,
forbearance or detention of money, interest at a rate in excess of the maximum
interest rate permitted to be charged by applicable law (the "Maximum Rate"). 
Neither the Borrower nor any guarantors, endorsers or other parties now or
hereafter becoming liable for payment of this Note shall ever be required to pay
interest on this Note at a rate in excess of the Maximum Rate and the provisions
of this paragraph shall control over all other provisions of this Note and any
other instruments now or hereafter executed in connection herewith which may be
in apparent conflict herewith. Lender expressly disavows any intention to charge
or collect excessive unearned interest or finance charges in the event the
maturity of this Note is accelerated.  If the maturity of this Note shall be
accelerated for any reason or if the principal of this Note is paid prior to the
end of the term of this Note, and as a result thereof the interest received for
the actual period of existence of the loan evidenced by this Note exceeds the
Maximum Rate, Lender shall refund to Borrower the amount of such excess or shall
credit the amount of such excess against the principal balance of this Note then
outstanding.  In the event that Lender shall collect monies which are deemed to
constitute interest which would increase the effective interest rate on this 
Note to a rate in excess of the Maximum Rate, all such sums deemed to constitute
interest in excess of the Maximum Rate shall, upon such determination, at the
option of Lender, be either immediately returned to Borrower or credited against
the principal balance of this Note then outstanding, without further penalty to
Lender.  By execution of this Note Borrower acknowledges that it believes the
loan evidenced by this Note to be non-usurious and agrees that if, at any time,
Borrower should have reason to believe that such loan is in fact usurious, it
will give Lender notice of such condition and Borrower agrees that Lender shall
have ninety (90) days in which to make appropriate refund or other adjustment in
order to correct such condition if in fact such exists.  The term "applicable
law" as used in this Note shall mean the laws of the State of New York or the
laws of the United States, whichever laws allow the greater rate of interest, as
such laws now exist or may be changed or amended or come into effect in the
future.

     Should the indebtedness represented by this Note or any part thereof be
collected at law or in equity or through any bankruptcy, receivership, probate
or other court proceedings or if this Note is placed in the hands of attorneys
for collection after default, Borrower and all endorsers, guarantors and 
sureties of this Note jointly and severally agree to pay in addition to the 
principal and interest due and payable hereon reasonable attorneys' and 
collection fees.

     Borrower and all endorsers, guarantors and sureties of this Note and all
other persons liable or to become liable on this Note severally waive 
presentment for payment, demand, notice of demand and of dishonor and nonpayment
of this Note, notice of intention to accelerate the maturity of this Note, 
protest and notice of protest, diligence in collecting, and the bringing of
suit against any other party, and agree to all renewals, extensions, 
modifications, partial payments, releases or substitutions of security, in whole
or in part, with or without notice, before or after maturity.

     This Note and the rights and duties of the parties hereunder shall be
governed for all purposes by the law of the State of New York and the law of the
United States applicable to transactions within such state.

     THIS AGREEMENT is made and entered into this 26th day of January, 1996,
by and between BIONOVA U.S. INC., a Delaware corporation (hereinafter BIONOVA)
and DNA PLANT TECHNOLOGY, a Delaware corporation (hereinafter DNAP).

                                WITNESSETH

     WHEREAS, BIONOVA, pursuant to the Loan Agreement dated as of even date
herewith ("Loan Agreement"), as the Lender, has agreed, subject to certain
conditions, to lend to DNAP, as the Borrower, $10,000,000 on a term loan
basis;

     WHEREAS, BIONOVA is willing to make the term loan under the Loan
Agreement only upon the condition, inter alia, that DNAP shall have executed
and delivered to BIONOVA an Assignment dated as of even date herewith of
patents and patent applications listed on the attached Schedule I;

     WHEREAS, immediately prior to the execution of such Assignment, DNAP and
BIONOVA executed a Non-Exclusive Patent License Agreement (the "NON-EXCLUSIVE
LICENSE"), which the parties hereto acknowledge continues through and beyond
the term of this Agreement, unless such Non-Exclusive Patent License Agreement
is earlier terminated pursuant to its terms.

     WHEREAS, BIONOVA, pursuant to the Loan Agreement and the Assignment, is
the owner of the right, title and interest in and to the patents and patent
applications listed on the attached Schedule I;

     WHEREAS, DNAP desires to obtain a sole license under the patents and
patent applications listed on the attached Schedule I;

     WHEREAS, BIONOVA is willing to grant such sole license to DNAP, for the
time and subject to the terms and conditions hereinafter set forth.

     NOW THEREFORE, for and in consideration of the mutual promises contained
herein, and for other good and valuable consideration, the parties hereto
agree as follows:

     1.   Definitions.  In this Agreement, the following terms shall have
the following meanings:

          a.   LICENSED PATENTS shall mean the patents and patent
               applications listed on the attached Schedule I, patents to
               be issued pursuant thereto, and all divisions,
               continuations, reissues, reexamination certificates,
               substitutes, and extensions thereof.

          b.   LICENSED PRODUCTS shall mean any product or process covered
               by one or more claims of the Licensed Patents.

          c.   COMMERCIALIZATION COLLABORATORS shall mean only those
               entities who, from the Closing Date until the time of a
               termination under this License Agreement, are in the chain
               of commercialization of the products made, used or sold by
               DNAP or by Affiliates of the DNAP.

          d.   RESEARCH SPONSORS shall mean those entities (other than
               entities listed on Schedule II with respect only to the
               Existing Licenses and extensions thereof) who, from the date
               hereof until the time of termination of this License
               Agreement shall fund research activities of DNAP or
               Affiliates of DNAP under agreements requiring funding to
               DNAP of at least $350,000 over a period not to exceed three
               years.

          e.   EXISTING LICENSES shall mean those license agreements with
               respect to the LICENSED PATENTS that are set forth in
               Schedule II hereto.

          f.   AFFILIATES means persons or entities controlling, controlled
               by or under common control with the party, as well as any
               majority owned entities of the party and of its other
               affiliates.  "Control" of an entity means either the power,
               directly or indirectly, to direct or cause the direction of
               the management and policies of the entity, whether by
               contract or otherwise, or the right to receive at least 50%
               of the profits from such entity.

     2.   License Grant to DNAP.

          a.   Upon execution of this Agreement and until termination of
DNAP's rights to compel a reconveyance of the LICENSED PATENTS pursuant to
Section 6.03 of the Loan Agreement, only for the Term indicated in Section
5(a) hereof, and subject to the NON-EXCLUSIVE LICENSE, BIONOVA hereby grants
to DNAP and its Affiliates a fully paid up royalty free sole license under the
LICENSED PATENTS to (i) use the LICENSED PATENTS, (ii) together with its
COMMERCIALIZATION COLLABORATORS, to make, have made, use and sell throughout
the world all LICENSED PRODUCTS, and (iii) to meet its obligations under the
Existing Licenses.

          b.   Upon termination of DNAP's rights to compel a reconveyance
of the LICENSED PATENTS pursuant to Section 6.03 of the Loan Agreement, and
for the Term indicated in Section 5(b) hereof and subject to the NON-EXCLUSIVE
LICENSE, BIONOVA hereby grants to DNAP and its Affiliates a fully paid up,
royalty free, non-exclusive license under the LICENSED PATENTS to (i) use the
LICENSED PATENTS, (ii) together with its COMMERCIALIZATION COLLABORATORS, to
make, have made, use and sell throughout the world all LICENSED PRODUCTS, and
(iii) to meet its obligations under the Existing Licenses.

     3.   DNAP's Right to Sublicense.  Except as specifically set forth
herein, during the term of this Agreement, DNAP shall not have a right to
sublicense the LICENSED PATENTS under this Agreement.  BIONOVA shall be deemed
to have consented to the EXISTING LICENSES and the NON-EXCLUSIVE LICENSE (and
to DNAP's continuing ability to receive all royalties and license fees
thereunder).  DNAP shall have the right to sublicense the LICENSED PATENTS to
RESEARCH SPONSORS at a commercially reasonable royalty rate acceptable to DNAP
whereby 50% of such royalties received by DNAP shall be paid, only if and to
the extent that there is any outstanding "Loan Indebtedness," as that term is
defined in the Loan Agreement, to BIONOVA within thirty (30) days of receipt
by DNAP and applied to such "Loan Indebtedness," and provided that the scope
of any such sublicense shall be (i) a non-exclusive license, and (ii) strictly
limited to the development and commercialization of the products and processes
resulting from the funded research program (collectively, the "Permitted
Sublicenses").  Allocations of royalty value in agreements with RESEARCH
SPONSORS between the LICENSED PATENTS and other intellectual property or
research services to be provided by DNAP shall be commercially reasonable. 
Without the written consent of BIONOVA, DNAP shall not be entitled to
materially amend or modify any such PERMITTED SUBLICENSE if such amendment or
modification would cause the sublicense to no longer meet the criteria for a
Permitted Sublicense.  Without the written consent of BIONOVA, DNAP shall not
be entitled to materially amend or modify any of the EXISTING LICENSES, if
such amendment or modification would have a materially adverse affect on the
value of the LICENSED PATENTS.  Subject to BIONOVA executing a Confidentiality
Agreement, DNAP agrees to send BIONOVA a complete and executed copy of each
PERMITTED SUBLICENSE or any modification of such PERMITTED SUBLICENSE or any
of the EXISTING LICENSES modified hereunder within 10 days of the final
execution or modification.

     4.   Limitation of Rights of BIONOVA.  While the sole license is in
effect, and other than pursuant to the NON-EXCLUSIVE LICENSE, BIONOVA shall
have no rights, without the prior written consent of DNAP (i) to grant any
licenses of the LICENSED PATENTS; or (ii) to make any use on its own behalf of
the LICENSED PATENTS including without limitation the right to make, have
made, use and sell throughout the world all LICENSED PRODUCTS.

     5.   Term.

          a.   The term of the sole license granted to DNAP in section 2(a)
shall be the earlier of three years from the date of execution hereof or until
termination of DNAP's right to compel a reconveyance of the LICENSED PATENTS
pursuant to Section 6.03 of the Loan Agreement.

          b.   The term of the non-exclusive license granted to DNAP in
section 2(b) shall be until expiration of the last to expire of the LICENSED
PATENTS.

     6.   Enforcement of LICENSED PATENTS.  As long as its sole license
remains in effect pursuant to Section 2(a) and subsequent to that time for the
sole purpose of meeting its obligations under the EXISTING LICENSES and the
PERMITTED SUBLICENSES, DNAP shall retain all rights to commence, appear in, or
defend or make decisions concerning any action or proceeding (including any
proceeding or prosecution in the United States Patent and Trademark Office)
including the right to compel the joinder of BIONOVA as a party, purporting to
affect, the LICENSED PATENTS.  If BIONOVA requests that DNAP take any action
regarding the matters set forth in this Section 6 and DNAP refuses or fails to
take such action on a timely basis, then, while the sole license remains in

               a.   Projects.  During the term of the Agreement, the
parties will discuss potential Projects.  Either party may propose such
Projects.  ELM will decide which particular Projects to undertake.  The
parties shall use their best efforts to agree on reasonable terms for all
Projects proposed, and DNAP shall not unreasonably refuse to agree to the
terms of any project proposed by ELM, including any confidentiality
restrictions regarding the subject matter and scope of a Project.

               b.   Project Plan.  Each such agreed Project shall have a

no consequential damages).

          2.3  Reports

               DNAP shall provide ELM with written reports on the progress
of each Project, on a quarterly basis or more often if requested by ELM.

          2.4  Oversight

               ELM shall have the right to oversee each Project, including
reasonable access to the DNAP employees and facilities being utilized in the
Project.

          2.5  License to Existing IP

               a.   License.  ELM shall have a worldwide royalty bearing
non-exclusive license under this Agreement with respect to DNAP IP solely to
the extent necessary or reasonably appropriate for ELM to commercialize the
Developed IP, including the right to make, have made, use and sell any Product
or technology resulting from a Project.

               b.   Royalty.  

                    (i)  ELM shall pay a royalty to DNAP for the use of
DNAP IP which royalty shall be at standard industry rates, with the specific
amount to be negotiated as Projects are identified; provided that the royalty
rate shall be equitably adjusted to the extent that the Non-Exclusive Patent
License between DNAP and Bionova U.S. Inc. remains in full force and effect.

                    (ii) With each royalty payment, ELM will provide to
DNAP a written royalty statement verified by the President or Chief Financial
Officer of ELM, setting forth the total sales identified by Product
designation or other basis upon which royalties are calculated during the
period covered by the statement.  DNAP shall have the right once per year to
designate an independent certified public accountant to inspect ELM's books
and records relating to the basis upon which royalties are calculated.

               c.   Exclusivity.  DNAP agrees that it will not undertake
to perform substantially the same research and development program as any
Project without the prior written consent of ELM.

          2.6  License to ELM IP

               a.   License.  If ELM IP is utilized in a Project and
incorporated in Developed IP, unless otherwise agreed in a Project Plan, DNAP
shall have a royalty bearing non-exclusive license under this Agreement with
respect to ELM IP solely to the extent necessary or reasonably appropriate for
DNAP to exercise its rights with respect to the Developed IP pursuant to
Section 4.2.

               b.   Royalty.  

                    (i)  DNAP shall pay a royalty to ELM for the use of
ELM IP which royalty shall be at standard industry rates, with the specific
amount to be negotiated as Projects are identified.

                    (ii) With each royalty payment, DNAP will provide to
ELM a written royalty statement verified by the President or Chief Financial
Officer of DNAP, setting forth the total sales identified by Product
designation or other basis upon which royalties are calculated during the
period covered by the statement.  ELM shall have the right once per year to
designate an independent certified public accountant to inspect DNAP's books
and records relating to the basis upon which royalties are calculated.


          2.7  Consultation.  The parties specifically understand that the
modification of phenotypic traits through biotechnology and genetic
engineering is of potential significant competitive importance to the
industry.  The parties need to work closely together to create and define
appropriate Projects.  DNAP will use its reasonable best efforts to
continually apprise ELM of scientific developments relating to ELM's products,
and ELM will apprise DNAP of those aspects of its competitive strategy and
development plans for its products which are necessary or useful to DNAP with
respect to its obligations hereunder.

     Article III.   Research Program Funding

          3.1  Payment by ELM

               ELM shall pay DNAP in accordance with the payment schedule
established for each Project in the Project Plan, provided that if DNAP fails
to provide the resources it is committed to provide to a Project, then, in
addition to its other remedies provided for herein, such payments shall be
equitably adjusted.

          3.2  Minimum Project Funding

               ELM and DNAP shall undertake Projects with payment schedules
that will generate payments to DNAP of at least $9,000,000 each three years,
up to a maximum of $30,000,000 during the ten-year period beginning on the
effective date hereof, with the understanding that if the minimum payments in
any year exceed the amounts payable for research services provided by DNAP
hereunder, then such excess shall be available as a credit towards future
services but shall not reduce ELM's obligation to continue minimum funding. 
Unless otherwise agreed by the parties, minimum funding of $625,000 shall be
paid to DNAP at the beginning of each calendar quarter during the term of this
Agreement until the maximum of $30,000,000 has been reached.

               The payment obligations of ELM shall be reduced by payments
by ELM to DNAP, if any, under other agreements (e.g., calling for joint
development of seed or crops) whereby DNAP provides research or development
services for ELM.  Similarly, in such event, DNAP's corresponding duty to
provide services hereunder shall be reduced.

          3.3  Payment Level

               Unless otherwise agreed in the Project Plan, ELM shall pay
DNAP all of DNAP's direct costs (including direct R&D overhead) plus an
industry standard operating margin, but in no event more than % of DNAP's
modified direct costs, as customarily computed by DNAP to include only
salaries, benefits, supplies and travel with respect to Project personnel.  

Article IV.    Rights to Results of Research Program

          4.1  Ownership Rights

               Subject to paragraph 4.2, ELM will own the entire right,
title and interest in all Developed IP, as well as all other inventions,
discoveries, improvements or other technology, arising out of each Project and
the Research Program, whether or not patentable, together with all patent
applications or patents based thereon, regardless of whether the Developed IP
are made by employees of ELM or employees of DNAP.  ELM will have the right to
file, prosecute and maintain patent applications for all Developed IP (at
ELM's expense if outside a Project Plan).  DNAP will promptly disclose to ELM
both the conception and the reduction to practice of Developed IP.  DNAP
hereby represents and agrees that all employees and other persons acting on
its behalf in performing its obligations under this Agreement will be
obligated under a binding written agreement or applicable law to assign to
DNAP or ELM, as directed, all Developed IP made or developed by such employee
or other person.  DNAP will make available to ELM or to ELM's authorized
attorneys, agents or representatives, (at ELM's expense if outside a Project
Plan) DNAP employees as necessary or appropriate to enable ELM to file,
prosecute and maintain patent applications and resulting patents with respect
to all Developed IP, for a period of time sufficient for ELM to obtain the
assistance it needs from such personnel.  If DNAP requests that ELM take any
action  in a proceeding incident to the Developed IP and ELM refuses or fails
to take such action, DNAP shall then have the right, but not the obligation,
in the name of ELM, to prosecute or defend any action or proceeding incident
to the Developed IP.  Any such action shall be at the sole expense of DNAP. 
DNAP shall have no obligation to undertake any such action, and if DNAP should
do so, it shall have no liability to ELM for the sufficiency or adequacy of
any such actions taken by DNAP.

          4.2  License Rights to Developed IP

               Unless otherwise agreed in a Project Plan, ELM hereby grants
to DNAP a perpetual, royalty-free (except as provided in Section 2.6 hereof)
(a) non-exclusive license, to use the Developed IP for research purposes only
within the Field, and (b) sole license to use the Developed IP outside the
Field (which sole license is subject to ELM's retained rights to use the
Developed IP outside the Field).  Such retained rights to use the Developed IP
outside the Field shall include, but not be limited to, the right to make
products and otherwise commercialize the Developed IP.  ELM will promptly, on
request, execute any further document or license with respect to DNAP's rights
under this Section 4.2.

          4.3  Notice of Patents Affecting Commercialization Rights

               During the term of the Research Program, DNAP shall use all
reasonable efforts to inform ELM of:

                    (a)  any patent owned by or patent application filed
by a third party of which DNAP is aware which claims a technology that DNAP is
considering for use in a Project, and that requires or may require one or both
of the parties to license rights thereunder in order to commercialize the
results of the Project; and

                    (b)  any possible alternative to such a patented
technology of which DNAP is aware.  In each such instance where DNAP is aware
of an alternative technology, the parties shall consider and discuss the
feasibility of using the alternative technology in place of the patented
technology.

Article V.     Confidentiality

          5.1  Duties

               Each party shall: (i) keep confidential and not disclose to
any third person or entity, (ii) restrict access to only those of its
employees and consultants who have reason to know for the purposes of this
Agreement, and (iii) use solely for purposes of this Agreement, any and all
information and biomaterials received from the other party under this
Agreement, and all Developed IP of which it obtains knowledge, except as
provided in paragraph 5.2 below.  Notwithstanding the foregoing each party
shall be free to use such information, biomaterials and Developed IP for
purposes of exercising its rights and fulfilling its duties under this
Agreement.

          5.2  Exceptions

               The duties of confidentiality, access restrictions and non-
use provided by paragraph 5.1(a) above shall not apply to information received
by one party ("Receiving Party") from the other party ("Disclosing Party") if
the information:

                    (a)  is public information at the time of disclosure
by the Disclosing Party to the Receiving Party;

                    (b)  subsequently becomes public information other
than by act or omission of the Receiving Party;

                    (c)  is already in the lawful possession of the
Receiving Party, as can reasonably be demonstrated by documentary evidence
from the Receiving Party, at the time of first disclosure by the Disclosing
Party to the Receiving Party; or

                    (d)  is independently developed by employees of the
Receiving Party who did not have access to the information.

Article VI.    Event of Default/Remedies/Other Termination Rights

          6.1  Event of Default

               It shall be an Event of Default hereunder if either party
(i) fails to pay any sums payable pursuant to this Agreement as and when they
are due; or (ii) materially breaches this Agreement.

          6.2  Termination

               The non-defaulting party shall have the right to terminate
this Agreement upon the occurrence of an Event of Default unless (i) the Event
of Default occurs under clause (i) of Section 6.1 and is cured within ten (10)
days after written notices thereof, or (ii) the Event of Default occurs under
clause (ii) of Section 6.1 and is cured within thirty (30) days after written
notice thereof, or (iii) the Event of Default occurs under clause (ii) of
Section 6.1 and is remediable but is not reasonably susceptible to cure within
such thirty (30) day period, then within such period of time as may be
required to cure the same if the defaulting party promptly commences to cure
such Event of Default within such thirty (30) day period and diligently
prosecutes such cure to completion as soon as is reasonably practicable; or
(iv) if such Event of Default is not one that can be remedied, the defaulting
party shall have taken reasonable steps within such thirty (30) day period to
prevent a recurrence of such breach; provided, however, that if such Event of
Default that cannot be remedied recurs in the same calendar year, the
nondefaulting party may, at its option, terminate this Agreement immediately
upon the recurrency by written notice to the other party.  ELM's rights to
Developed IP and DNAP IP shall survive any termination by ELM pursuant to this
Agreement.  DNAP's License rights to Developed IP shall survive any
termination by DNAP pursuant to this Agreement.

          6.3  Other Remedies

               In addition to all other remedies specified in Article 6,
the non-defaulting party shall have the right to pursue any and all available
legal or equitable remedies for the breach.

          6.4  No Consequential Damages

               In no event will either party be liable to the other or any
third party for any indirect, incidental or consequential damages with respect
to the performance or non-performance of this Agreement, whether arising out
of breach of warranty, breach of contract, tort (including negligence), strict
products liability or otherwise, even if advised of the possibility of such
damage or if such damage could have been reasonably foreseen, except only in
case of personal injury where applicable law requires such liability.

                  NON-EXCLUSIVE PATENT LICENSE AGREEMENT


     THIS LICENSE AGREEMENT ("LICENSE AGREEMENT") is made and entered into
this 26th day of January, 1996, by and between BIONOVA U.S. INC., a Delaware
corporation (hereinafter BIONOVA) and DNA PLANT TECHNOLOGY CORPORATION, a
Delaware corporation (hereinafter DNAP).

                                WITNESSETH

     WHEREAS, BIONOVA desires to have a non-exclusive license as recited
herein under the patent and patent applications listed in the attached
Schedule 1; and

     WHEREAS, DNAP is willing to grant such license to BIONOVA, subject to
the terms and conditions hereinafter set forth.

     NOW THEREFORE, for and in consideration of the mutual promises contained
herein, and for other good and valuable consideration, the parties hereto
agree as follows:

     1.   Definitions.  In this LICENSE AGREEMENT, the following terms shall
have the following meanings:

          a.   LICENSED PATENTS shall mean the patents and patent
applications listed on the attached Schedule 1, patents to be issued pursuant
thereto, and all divisions, continuations, reissues, reexamination
certificates, substitutes, and extensions thereof.

          b.   LICENSED PRODUCTS shall mean any product or process covered
by one or more claims of the LICENSED PATENTS.

          c.   ROYALTY BEARING PRODUCTS shall mean the LICENSED PRODUCTS
that are covered by one or more issued and not lapsed or expired claims of one
or more of the LICENSED PATENTS.

          d.   NET SALES shall mean the gross invoice price of ROYALTY
BEARING PRODUCTS sold by BIONOVA or its Sublicensees minus documented returns
and allowances for defective goods.  The gross invoice price shall not include
any sales, use or value added taxes.

     2.   License Grant To BIONOVA.  DNAP grants to BIONOVA for the term of
this Agreement a non-exclusive license under LICENSED PATENTS to use the
LICENSED PATENTS and to make, have made, use and sell LICENSED PRODUCTS,
except that such license does not include rights in the areas listed in
Schedule 2.  The license is non-transferable; provided, that DNAP consents to
BIONOVA'S sublicense of its rights hereunder to its Affiliates as of the date
of this Agreement provided that each such Sublicensee agrees to become bound
by the terms and conditions of this License (the "Sublicensees").  For
purposes of this provision, "Affiliates" means persons or entities
controlling, controlled by or under common control with the party, as well as
any majority owned entities of the party and of its other affiliates, and
"control" of an entity means either the power, directly or indirectly, to
direct or cause the direction of the management and policies of the entity,
whether by contract or otherwise, or the right to receive at least 50% of the
profits from such entity.

     3.   Royalties.

          a.   BIONOVA shall pay DNAP a running royalty fee of $250,000.00
for each full quarter during which this LICENSE AGREEMENT is in effect;
provided, however, the fee for the calendar quarter ending March 31, 1996
shall be $50,000 and the fee for the calendar quarter ending June 30, 1996
shall be $125,000.00.  For any portion of a quarter during which this LICENSE
AGREEMENT is in effect BIONOVA shall pay DNAP a percentage of the applicable
quarterly fee equal to the number of days of such quarter divided by 91 days,
multiplied by the applicable quarterly fee.  

          b.   BIONOVA may pay any royalty or other amounts due or payable
under this LICENSE AGREEMENT by crediting the amount of such royalty or other
payment against any indebtedness owed to BIONOVA by DNAP pursuant to that
certain Loan Agreement executed by and between DNAP and BIONOVA dated of even
date herewith.

          c.   BIONOVA shall make the royalty payments set forth in
subparagraphs (a) and (b) hereof sixty (60) days after the close of each
quarter.

          d.   With each royalty payment, BIONOVA will provide to DNAP a
written royalty statement verified by the President or Chief Financial Officer
of BIONOVA, setting forth the NET SALES identified by product designation upon
which royalties are calculated during the period covered by the statement. 
DNAP shall have the right once per year to designate an independent certified
public accountant to inspect BIONOVA's books and records relating to NET SALES
upon which royalties are calculated.

     4.   BIONOVA's Option To Convert To Fully-Paid License.  BIONOVA may,
at any time prior to September 30, 1996, notify DNAP that it is electing to
convert to a fully paid LICENSE with respect to the quarterly license fees
owed by BIONOVA under subparagraph 3(a) by paying the sum of $1,500,000 plus a
royalty equal to 2.5% of the NET SALES of ROYALTY BEARING PRODUCTS sold by
BIONOVA or its Sublicensees during any quarter subsequent to the election
during which this LICENSE AGREEMENT is in effect, which fully paid LICENSE
shall continue in full force and effect and shall not terminate until the last
to expire of the LICENSED PATENTS.  At any time subsequent to September 30,
1996, if BIONOVA has not made the above described election, BIONOVA may upon
thirty (30) days notice to DNAP, convert to a fully paid royalty-free license
by paying DNAP the following sum as a lump sum payment for a fully paid up
license to BIONOVA and its Sublicensees:  an amount when discounted, at a
discount rate of ten percent (10%), which, if added to the discounted stream
of any and all royalty payments made pursuant to subparagraph 3(a) hereunder
(with the exception of the March 31, 1996 and June 30, 1996 payments), would
yield a total present value as of the date of this Agreement of $5,000,000.00. 


     5.   Enforcement of LICENSED PATENTS.  DNAP will be solely responsible
at its own expense for using all reasonable efforts to prosecute and enforce
LICENSED PATENTS owned by DNAP; provided, however if BIONOVA requests that
DNAP take any reasonable action to prosecute and enforce the  LICENSED PATENTS
and DNAP refuses or fails to take such action on a timely basis, BIONOVA shall
be permitted and authorized, in the name of DNAP or in the name of BIONOVA as
appropriate, to use all reasonable efforts to prosecute and enforce LICENSED
PATENTS.  DNAP will provide BIONOVA with reasonable assistance in such
prosecution and enforcement.  BIONOVA shall have no obligation to undertake
any such action, and if BIONOVA should do so, BIONOVA shall have no liability
to DNAP for the sufficiency or adequacy of any such actions taken by BIONOVA. 

     6.   Notices.  All notices, demands, requests, and other communications
required or permitted hereunder shall be in writing and shall be deemed to
have been given when received by BIONOVA or DNAP, as the case may be, at the
respective addresses set forth below or as BIONOVA or DNAP may from time to
time designate by written notice to the other:

been contained herein.

remedies granted herein and available at law or in equity, and these same
rights and remedies shall be cumulative and may be pursued separately,
successively, or concurrently against the other party, or to the LICENSED
PATENTS at the sole discretion of the pursuing party.  The exercise or failure
to exercise any of the same shall not constitute a waiver or release thereof
or of any other right or remedy, and the same shall be non-exclusive.

     10.  Form and Substance.  All documents, certificates, and other items
required under this LICENSE AGREEMENT to be executed and/or delivered to a

parties hereto acknowledge that immediately subsequent to the execution of
this LICENSE, DNAP will be granting an Assignment of its ownership of the
LICENSED PATENTS to BIONOVA as security for repayment of its obligations under
the Loan Agreement.  The Assignment shall not affect the rights or obligations
of either party hereunder.  Notwithstanding the above, a party may assign this
LICENSE AGREEMENT to a successor of all or substantially all of its business
without the prior written consent of the other party, provided however, that
no such assignment shall be valid unless the assignee assumes all of the
duties and obligations of the assigning party.

acts, as may be necessary or appropriate in order to carry out the intent and

          b.  Exceptions:  The duties of confidentiality, access
restrictions and non-use provided by subparagraph (a) above shall not apply to
information received by BIONOVA from DNAP if the information:

                    (i)  is public information at the time of disclosure
by DNAP to BIONOVA;

                    (ii) subsequently becomes public information other
than by act or omission of BIONOVA;

                    (iii)     is already in the lawful possession of BIONOVA,

     19.  Term and Termination.  This Agreement shall continue until the

have the unilateral right to terminate this LICENSE AGREEMENT by giving DNAP
thirty (30) days written notice of such termination together with payment of
all amounts due hereunder through the date of termination; provided, however,
upon termination BIONOVA and its Affiliates shall be required (i) to return

retain a copy thereof to be held in confidence for the sole purpose of
preserving a record for any future litigation. and (ii) to cease any and all
use of the LICENSED PATENTS pursuant to this LICENSE AGREEMENT.  BIONOVA's
obligation to pay royalties under this LICENSE AGREEMENT shall cease upon such
termination.

January 29, 1996


                Unit of Empresas La Moderna To Combine with
                           DNA Plant Technology

ELM to Combine Operating Subsidiaries, Inject Cash, and Guarantee Long-Term
         R&D Contracts in Exchange for Majority Ownership Position


Monterrey, Mexico, January, 29, 1996 -- Empresas La Moderna S.A. de C.V.
(NYSE/ADR:ELM) today announced it has signed a definitive agreement to combine
its fresh produce subsidiary, Bionova, with DNA Plant Technology Corporation
(Nasdaq:DNAP) in exchange for an approximate 70% interest in the new entity. 
Under the terms of the agreement, approved by the DNAP Board of Directors, the
ELM unit agrees to combine the controlling interests in its $200 million fresh
produce business, Bionova S.A. de C.V. with DNAP under a new holding company,
DNAP Holding Corporation, and to inject $10 million in cash.  At closing, ELM,
with its related companies, Asgrow Seed Company, Petoseed, Royal Sluis and
Agroindustrias Moderna, among others, will enter into contracts with DNAP
which will focus ELM's biotech R&D in DNAP, and will provide $30 million in
research funding over a ten-year period.

Following the transaction, it is anticipated that the common shares of the new
holding company, DNAP Holding Corporation, will be listed on Nasdaq.

Alfonso Romo Garza, Chairman and Chief Executive Officer of ELM, said, "This
agreement represents another important step in achieving our stated objective
of attaining global leadership in the agro-biotech and seed industries.  We
believe the synergies and resulting benefits from this transaction should
enhance shareholder value, bring greater opportunities to the combined
entities and position ELM and its subsidiaries in the forefront of the
industry." 

Mr. Romo noted that DNAP has developed worldwide leadership in the genetic
transformation of fruits and vegetables.  ELM through its Seminis subsidiary
has world-class elite germplasm, an essential component for the delivery of
the promise of biotechnology. ELM's $200 million Bionova division, one of the
fastest growing producers and distributors of quality fresh produce, is
positioned to rapidly commercialize new products on a large scale.  The
combination of these entities should provide an excellent opportunity to meet
the growing consumer need for quality, differentiated fresh products in a $50
billion retail market.

Under the terms of the agreement, holders of existing DNAP common stock will
receive one common share of DNAP Holding Corporation for each share of DNAP
common stock; each share of DNAP convertible preferred stock will receive
6.8375 shares of DNAP Holding Corporation common stock; and each share of DNAP
Series A preferred stock will receive 1,000 shares of DNAP Holding Corporation
common stock.  The transaction is subject to approval of DNAP common
shareholders and other conditions.  The transaction is expected to close in
the second quarter of 1996.  JP Morgan are advising ELM, and Piper Jaffray and
BioScience Securities are advising DNAP.

As a result of the transaction, ELM through its agro-biotech division
subsidiaries will own approximately 70% of the common shares and designate
eight of the eleven seats of the new company's Board of Directors.  The Board
of Directors will include six ELM representatives, Robert Serenbetz, current
Chairman of DNAP, and four independent directors, three of whom are current
board members of DNAP.  Approval of a majority of a committee of independent
directors will, under a Governance Agreement, be required for certain matters,
including certain material transactions and transactions with ELM or its
affiliates.

"This business combination will create a leading-edge, technology-based
branded produce company, combining the biotechnology and value added produce
development expertise of DNAP with the production, distribution and scientific
strengths of Bionova and Seminis," stated Robert Serenbetz.  "We started the
process of looking for a strategic partner several months ago that could offer
DNAP shareholders the best course for long-term success.  The Board believes
this transaction is in the best long-term interests of all DNAP shareholders
and offers a promising outlook for the future."

Empresas La Moderna, a Pulsar Internacional company based in Monterrey,
Mexico, has operations in three divisions:  Cigarettes, Agrobiotechnology and
Packaging.  Bionova and Seminis are a part of the agrobiotechnology unit of
ELM.  Its Bionova subsidiary is a leading grower and shipper of fruits and
vegetables in Mexico, and has distribution and marketing operations in the
U.S., Mexico and Canada.  With 1995 sales of $200 million, Bionova has grown
six-fold since inception in 1992.  Bionova is a fully integrated fresh produce
leader in North America producing and distributing through its operating
subsidiaries a broad range of premium produce products, including tomatoes,
peppers and melons under the brand name Master's Touch.  Seminis, one of the
top five global producers of vegetable and agronomic seeds, holds a leading
22% worldwide market share in the vegetable seed category.  Through a
combination of several strategic mergers of leading seed companies -- Asgrow
Seed Company, Petoseed and Royal Sluis -- Seminis today owns the world's
largest vegetable germplasm bank, operates R&D facilities in more than 25
countries and has sales of $535 million worldwide.

DNA Plant Technology Corporation, headquartered in Oakland, California, is a
leading agribusiness biotechnology company focused on developing and marketing
premium branded fresh and processed fruits and vegetables using advanced
breeding, genetic engineering, and other biotechnologies.  Fresh World Farms,
a wholly-owned subsidiary of DNAP, markets a line of premium vegetables under
the Fresh World Farms brand, including tomatoes, carrot bites (baby whole
carrots), sweet red mini-peppers, and VegiSnax  carrot sticks.  DNAP's two-
track strategy uses advanced breeding to develop and market improved premium
products for today, while using genetic engineering to improve flavor and
shelf life of its products for tomorrow.

While the DNAP Board enthusiastically supports the ELM offer, in compliance
with its fiduciary obligations, the Board and its advisors are available to
receive inquiries from other parties interested in the possible acquisition of
or merger with DNAP and, as appropriate, to provide information and enter into
discussions and negotiations with such parties in connection with such
indicated interest.
