(1) Monsanto Company ("Monsanto") and Calgene, Inc. ("Calgene") have entered
    into an Agreement and Plan of Reorganization which provides for a series
    of transactions (collectively, the "Reorganization") pursuant to which,
    among other things, (i) a wholly-owned subsidiary of the Registrant will
    be merged with and into Calgene and all outstanding shares of Calgene's
    Common Stock will be converted into the Registrant's Common Stock and (ii)
    Monsanto will contribute certain assets to the Registrant in exchange for
    shares of the Registrant's Common Stock. This Registration Statement
    covers the maximum number of shares of the Registrant's common stock which
    are expected to be issued to Calgene stockholders in connection with the
    Reorganization plus the maximum number of shares of the Registrant's
    Common Stock which are reserved for issuance pursuant to the exercise of
    outstanding options under Calgene's stock option plans that will be
    assumed by the Registrant upon consummation of the Reorganization and will
    be exercisable prior to April 15, 1996.
(2) Estimated solely for the purpose of calculating the registration fee
    pursuant to Rule 457(c) under the Securities Act of 1933, as amended (the
    "Securities Act"), and based upon the high and low sale prices of Calgene
    Common Stock as quoted on the Nasdaq National Market on January 30, 1996.
(3) A fee of $39,696.00 was previously paid by Calgene pursuant to Rules 14a-6
    promulgated under the Securities Exchange Act of 1934, as amended, in
    connection with the filing of the preliminary Proxy Statement/Prospectus
    on November 7, 1995. Pursuant to Rule 457(b) under the Securities Act,
    such fee is being credited against the registration fee, and accordingly,
    an additional fee of $21,672 is being paid upon filing of this
    Registration Statement.
                                ---------------
  THE REGISTRANT HEREBY AMENDS THIS REGISTRATION STATEMENT ON SUCH DATE OR
DATES AS MAY BE NECESSARY TO DELAY ITS EFFECTIVE DATE UNTIL THE REGISTRANT
SHALL FILE A FURTHER AMENDMENT WHICH SPECIFICALLY STATES THAT THIS
REGISTRATION STATEMENT SHALL THEREAFTER BECOME EFFECTIVE IN ACCORDANCE WITH
SECTION 8(A) OF THE SECURITIES ACT OF 1933 OR UNTIL THE REGISTRATION STATEMENT
SHALL BECOME EFFECTIVE ON SUCH DATE AS THE COMMISSION, ACTING PURSUANT TO SAID
SECTION 8(A), MAY DETERMINE.

                   NOTICE OF SPECIAL MEETING OF STOCKHOLDERS
 
                               February 6, 1996
 
 To the Stockholders of Calgene, Inc.:
 
  NOTICE IS HEREBY GIVEN that a Special Meeting of Stockholders (the "Special
Meeting") of Calgene, Inc., a Delaware corporation ("Calgene"), will be held
on Monday, March 25, 1996, at the Varsity Theatre, 616 2nd Street, Davis,
California, commencing at 9:00 a.m., local time, for the following purposes:
 
    1. To approve the Agreement and Plan of Reorganization dated as of
  October 13, 1995 (the "Reorganization Agreement"), between Calgene and
  Monsanto Company, a Delaware corporation ("Monsanto"), and the related Plan
  of Merger, under which Calgene and Tomato Investment Associates, Inc., a
  Delaware corporation and a wholly-owned subsidiary of Monsanto ("TIA"),
  which will, upon the Effective Time (as defined in the Reorganization
  Agreement), own the entire equity interest in Gargiulo, L.P., a Delaware
  limited partnership, will become wholly-owned subsidiaries of a newly-
  formed holding company, Calgene II, Inc., a Delaware corporation ("Newco"),
  pursuant to: (i) a merger of a wholly-owned subsidiary of Newco with and
  into Calgene and the conversion of each outstanding share of Calgene Common
  Stock, par value $0.001 per share (the "Calgene Common Stock"), into the
  right to receive one share of Common Stock, par value $0.001 per share, of
  Newco (the "Newco Common Stock"), followed immediately by (ii) the exchange
  by Monsanto of all of the outstanding shares of capital stock of TIA and
  certain other assets for that number of shares of Newco Common Stock
  representing 49.9% of the outstanding shares of Newco Common Stock upon the
  Effective Time (the "Merger Proposal"). Upon the Effective Time, Newco will
  be renamed "Calgene, Inc." A vote in favor of the Merger Proposal shall be
  deemed to be ratification of (i) the assumption by Newco of Calgene's 1991
  Stock Option Plan, (ii) the assumption by Newco of Calgene's 1990 Employee
  Stock Purchase Plan, (iii) the adoption of the Newco 1996 Stock Option Plan
  and (iv) the election of the eight directors of Newco specified in the
  accompanying Proxy Statement/Prospectus.
 
    2. To transact such other business as may properly come before the
  Special Meeting or any postponements or adjournments thereof.
 
  The Board of Directors of Calgene has fixed the close of business on January
25, 1996, as the record date for the determination of stockholders entitled to
notice of and to vote at the Special Meeting and any adjournment or
postponement thereof. A list of stockholders entitled to vote at the Special
Meeting will be available for examination by any stockholder, at the
headquarters of Calgene, not less than ten days prior to the Special Meeting.
 
  The affirmative vote of the holders of a majority of the outstanding shares
of Calgene Common Stock is necessary to approve the Merger Proposal. Holders
of Calgene Common Stock are not entitled to dissenters' appraisal rights in
connection with the Merger Proposal.
 
  All stockholders are cordially invited to attend the Special Meeting in
person. However, to ensure your representation at the Special Meeting, you are

  The following is a summary (the "Summary") of certain information contained
elsewhere in this Proxy Statement/Prospectus. Reference is made to, and this
Summary is qualified in its entirety by, the more detailed information
contained, or incorporated by reference, in this Proxy Statement/Prospectus
and the Annexes hereto. Unless otherwise defined herein, capitalized terms
used in this Summary have the respective meanings ascribed to them elsewhere
in this Proxy Statement/Prospectus. Unless the context otherwise requires, all
references to Newco, Calgene, TIA, Gargiulo L.P. and Collier Farms include
their respective consolidated or unconsolidated, if any, subsidiaries.
Stockholders of Calgene are urged to read this Proxy Statement/Prospectus and
the Annexes hereto in their entirety.
 
INTRODUCTION
 
  On October 13, 1995, Calgene entered into an Agreement and Plan of
Reorganization with Monsanto, pursuant to which Calgene and Monsanto agreed,
subject to the approval of Calgene stockholders and the fulfillment of certain
other conditions, to a series of transactions referred to herein as the
"Reorganization." See "Approval of the Merger."
 
  The first step of the Reorganization involves the merger (the "Merger") of
Calgene Acquisition Corp., a Delaware corporation and wholly-owned subsidiary
of Newco, with and into Calgene. Calgene will be the surviving corporation in
the Merger and will become a wholly-owned subsidiary of Newco. Upon the
Effective Time (as defined herein), Newco will change its name to "Calgene,
Inc." and Calgene will change its name to "Calgene Technology Corporation."
The senior management of Calgene immediately prior to the Effective Time,
other than Roderick N. Stacey, will become the senior management of Newco
following the Effective Time. See "Approval of the Merger" and "Calgene II,
Inc."
 
  In connection with the Merger, each stockholder of Calgene will be entitled
to receive one share of Newco Common Stock for each share of Calgene Common
Stock held by such stockholder immediately prior to the Effective Time. The
shares of Newco Common Stock to be received by Calgene stockholders in the
Merger are registered under the Securities Act and will be listed on the
Nasdaq National Market under the symbol "CGNE." See "Approval of the Merger."
 
  The second step of the Reorganization involves the exchange by Monsanto of
(i) all outstanding shares of capital stock of Tomato Investment Associates,
Inc., a Delaware corporation and wholly-owned subsidiary of Monsanto ("TIA"),
whose principal asset is the entire equity interest in Gargiulo, L.P., a
Delaware limited partnership ("Gargiulo L.P."), (ii) $30 million in cash (less
amounts previously advanced to Calgene under an existing subordinated
promissory note, under which $18 million was outstanding at December 31, 1995)
and (iii) certain technology licenses, for that number of shares of Newco
Common Stock representing 49.9% of the outstanding shares of Newco Common
Stock upon the Effective Time. See "Tomato Investment Associates, Inc." The
shares of Newco Common Stock to be received by Monsanto in the Reorganization
initially will not be registered under the Securities Act. However, upon the
occurrence of certain events, Monsanto will have certain registration rights
with respect to its shares of Newco Common Stock. Monsanto will also have
certain rights with respect to the election of directors of Newco. See "The
Reorganization Agreement and Related Agreements--The Stockholders Agreement."

Corporation," and (ii) all of the outstanding shares of capital stock of TIA,
which owns the entire equity interest in Gargiulo
 
                                       7

of $5.6 million for the quarter ended December 31, 1994. The results for the
second quarter ended December 31, 1995 reflect a non-recurring technology
license sale of $3.8 million.
 
  In January 1995, Calgene determined to terminate its joint venture for
potatoes with Kirin Brewery, and expects to incur a charge of approximately
$1.0 million in the third quarter ending March 31, 1996 in connection with
such termination.
 
 Gargiulo L.P.
 
  Gargiulo L.P. had estimated revenues of $19.7 million and an estimated net
loss of approximately $3.2 million in the fiscal quarter ended December 31,
1995. The major contributors to the net loss were a loss in the California
tomato operations of approximately $1.3 million and expenses related to the
upcoming launch of the branded tomato program of approximately $1.2 million.
The loss from the California tomato operations reflected very low yields at
the end of the season and low prices. The low yields were primarily due to a
virus, but also reflected pricing which made it uneconomical to harvest at
times.
 
  Results for the quarter were also affected by lower than normal volume in
Gargiulo L.P.'s Naples operations due to cooler than normal weather, which
delayed harvest.
 
  In 1994 and 1995 the market experienced a state of oversupply in the months
of February, March and April, as a result of increased Mexican exports. Prices
during these periods were depressed as a result of the oversupply. It is
highly possible that a recurrence of such oversupply will take place in
February, March and April of 1996. Furthermore, Gargiulo L.P.'s financial
position will be even riskier than it has been in past years if its
acquisition of Collier Farms is completed. Under the terms of its agreement
with Collier Farms, Gargiulo L.P. will assume all expenses incurred by Collier
Farms since July 1, 1995 which relate to the production of Collier Farms'
1995-96 crop. Depressed pricing might result in a loss on the Collier Farms
crops for the season, with proceeds from the sales of such crops insufficient
to pay Collier Farms' related expenses.
 
  Gargiulo L.P. had estimated working capital of negative $3.3 million at
December 31, 1995. This represents a decrease of $15.9 million from September
30, 1995, when working capital was $12.6 million. This decrease resulted from
the combination of the reclassification of its line of credit from long-term
to current liabilities, the loss incurred during the period and capital
expenditures.
 
  Gargiulo L.P. conducts its California tomato operations through a
partnership in which it has a two-thirds interest and its partner, Dresick
Farms, Inc. ("Dresick Farms"), has a one-third interest. Dresick Farms has
indicated it intends to withdraw from the partnership in 1996. Gargiulo L.P.
intends to continue to run the California tomato operation as a wholly-owned
division of Gargiulo L.P. after Dresick Farms withdraws.
 
 Collier Farms
 
  Based on a preliminary analysis, Collier Farms estimates it incurred a loss
of between $1.0 million and $2.0 million for the fiscal quarter ended December
31, 1995. The estimate is based on ultimate total yields which will be
determined only after the acreage is completely harvested. Typically, Collier
Farms harvests the same acreage two or three times through the end of the
fiscal year, dependent upon the pricing at the time harvest decisions are
made.
 
  The estimated loss includes related party management fees of $300,000 and
interest expense of $308,000.
 
  The loss is primarily a result of reduced volume caused by unfavorable
weather conditions. Additionally, for the crop that has been sold, selling
prices averaged below normal expectations. As is standard for Collier Farms,
over 70% of the entire crop is expected to be harvested in the months of
January through May.

THE SPECIAL MEETING
 
 Date and Place of the Special Meeting
 
  The Special Meeting will be held on Monday, March 25, 1996, at the Varsity
Theatre, 616 2nd Street, Davis, California, commencing at 9:00 a.m., local
time. See "The Special Meeting."
 
 Stockholders Entitled to Vote
 
  Holders of record of shares of Calgene Common Stock at the close of business
on January 25, 1996 (the "Record Date") are entitled to notice of and to vote
at the Special Meeting. On the Record Date, there were 30,264,257 shares of
Calgene Common Stock outstanding, each of which will entitle the holder
thereof to one vote on each matter to be acted upon or which may properly come
before the Special Meeting and all adjournments thereof.
 
 Matters to be Considered at the Special Meeting
 
  The purpose of the Special Meeting is to approve the Agreement and Plan of
Reorganization dated as of October 13, 1995 (the "Reorganization Agreement"),
between Calgene and Monsanto, and the related Plan of Merger, under which
Calgene and TIA will become wholly-owned subsidiaries of Newco, pursuant to:
(i) a merger of a wholly-owned subsidiary of Newco with and into Calgene and
the conversion of each outstanding share of Calgene Common Stock immediately
prior to the Effective Time into the right to receive one share of Newco
Common Stock, followed immediately by (ii) the exchange by Monsanto of all of
the outstanding shares of capital stock of TIA, $30 million in cash (less
amounts previously advanced to Calgene under an existing subordinated
promissory note, under which $18 million was outstanding at December 31,
1995), and certain technology licenses, for that number of shares representing
49.9% of the outstanding shares of Newco Common Stock upon the Effective Time
(collectively, the "Merger Proposal"). Upon the Effective Time, Newco will be
renamed "Calgene, Inc." A vote in favor of the Merger Proposal shall be deemed
to be ratification of (i) the assumption by Newco of Calgene's 1991 Stock
Option Plan, (ii) the assumption by Newco of Calgene's 1990 Employee Stock
Purchase Plan, (iii) the adoption of the Newco 1996 Stock Option Plan and (iv)
the election of the eight directors of Newco specified in this Proxy
Statement/Prospectus. See "The Special Meeting--Matters to be Considered at
the Special Meeting" and "Calgene II, Inc.--Directors and Executive Officers."
 
 Vote Required
 
  The approval of the Merger Proposal will require the affirmative vote of the
holders of a majority of the outstanding shares of Calgene Common Stock. See
"The Special Meeting--Voting at the Special Meeting; Record Date." As of
September 30, 1995, directors and executive officers of Calgene and their
affiliates may be deemed to beneficially own approximately 1.9% of the
outstanding shares of Calgene Common Stock. Each director and executive
officer of Calgene has advised Calgene that he intends to vote or direct the
vote of all shares of Calgene Common Stock over which he has voting control
FOR approval of the Merger Proposal.
 
 Effects of Abstentions and "Broker Non-Votes"
 
  Shares of Calgene Common Stock held by stockholders who abstain from voting
will be counted for determining the presence or absence of a quorum for the
transaction of business at the Special Meeting but will not be counted as
votes for or against the Merger Proposal. With respect to broker non-votes,
there is case law to the effect that such shares may be counted for
determining the presence or absence of a quorum, but should not be counted for
purposes of determining the number of shares voting with respect to any
proposal on which the broker has expressly not voted. Accordingly, broker non-
votes will not be counted as voting shares of Calgene Common Stock with
respect to the Merger Proposal at the Special Meeting. Since the Merger
Proposal requires the affirmative vote of a majority of the outstanding shares
of Calgene Common Stock, an abstention or broker non-vote will have the same
effect as a vote against the Merger Proposal.

THE REORGANIZATION AGREEMENT
 
 Effect of the Reorganization
 
  Upon the consummation of the Reorganization, Calgene and TIA will each
become a wholly-owned subsidiary of Newco, holders of Calgene Common Stock
immediately prior to the Effective Time will have the right to receive, in the
aggregate, 50.1% of the then outstanding shares of Newco Common Stock and
Monsanto will receive 49.9% of the then outstanding shares of Newco Common
Stock. Upon the Effective Time, Monsanto will also contribute to Newco $30
million in cash (less amounts previously advanced to Calgene under an existing
subordinated promissory note, under which $18 million was outstanding at
December 31, 1995) and certain licenses of technology relating to fatty acid
composition, fruit ripening control, virus and insect resistance, carbohydrate
partitioning and gene expression. Immediately following the Reorganization,
Gargiulo L.P. will be liquidated and TIA will succeed to all of the assets and
liabilities of Gargiulo L.P. See "The Reorganization Agreement and Related
Agreements--Gargiulo Reorganization Agreement."
 
 Effective Time of the Reorganization
 
  It is anticipated that the Reorganization will become effective as promptly
as practicable after the holders of Calgene Common Stock approve the Merger
Proposal and all other conditions to the Reorganization have been satisfied or
waived (the "Effective Time"). It is anticipated that, assuming all conditions
are met, the Reorganization will close shortly after the Special Meeting.
 
 Recommendations; Fairness Opinion
 
  The Calgene Board has unanimously approved the Reorganization Agreement and
the Reorganization and unanimously recommends that holders of Calgene Common
Stock vote FOR the Merger Proposal. In making its recommendation with respect
to the Merger Proposal, the Calgene Board considered, among other things, the
oral opinion of Montgomery Securities ("Montgomery"), Calgene's financial
advisor, delivered to the Calgene Board on October 5, 1995, and subsequently
confirmed in writing as of such date, to the effect that the consideration to
be received by Newco in exchange for 49.9% of the Newco Common Stock pursuant
to the Reorganization Agreement, consisting of all of the capital stock of
TIA, plus certain intellectual property and research and development assets
and a combination of cash and forgiveness of indebtedness in the aggregate
amount of $30 million was fair to Calgene, from a financial point of view, as
of such date.
 
  A copy of the opinion of Montgomery (the "Montgomery Opinion"), which sets
forth the assumptions made, matters considered and scope of Montgomery's
review, is attached to this Proxy Statement/Prospectus as Annex C and should
be read in its entirety. See "Approval of the Merger--Opinion of Calgene's
Financial Advisor," which also contains a description of the fees to be paid
to Montgomery.
 
  For a discussion of the factors considered by the Calgene Board in reaching
its decisions, see "Approval of the Merger--Calgene's Reasons for the
Reorganization; Recommendation of the Calgene Board of Directors."
 
 Interests of Certain Parties
 
  As of September 30, 1995, directors and executive officers of Calgene and
their affiliates may be deemed to beneficially own approximately 1.9% of the
outstanding shares of Calgene Common Stock. Each director and executive
officer of Calgene has advised Calgene that he intends to vote or direct the
vote of all the shares of Calgene Common Stock over which he has voting
control FOR approval of the Merger Proposal. See "Calgene, Inc.--Executive
Compensation" and "Related Party Transactions" for a description of the terms
of employment agreements between Calgene and TIA and certain of their
respective executive officers.
 
 Directors and Executive Officers of Newco After the Reorganization
 
  Pursuant to the Stockholders Agreement (as defined herein), the Board of
Directors of Newco (the "Newco Board") at the Effective Time shall consist of
nine directors, of which two shall be executive officers (Roger H. Salquist
and another executive officer to be designated), three shall be designated by
Calgene (Howard D. Palefsky, Carl V. Stinnett and Allen J. Vangelos) and four
shall be designated by Monsanto (Hendrik A. Verfaillie, Robert T. Fraley,
Jeffrey D. Gargiulo and John E. Robson). See "The Reorganization Agreement and
 
                                      11
<PAGE>
 
Related Agreements--The Reorganization Agreement--Representation on the Newco
Board" and "Calgene II, Inc.--Directors and Executive Officers."
 
  Upon the Effective Time, the executive officers of Calgene immediately prior
to the Effective Time, together with Jeffrey D. Gargiulo, the Chairman and
Chief Executive Officer of Gargiulo L.P., will be the principal executive
officers of Newco, except that Roderick N. Stacey, the President and Chief
Operating Officer of Calgene, has indicated that he intends to resign
following the Effective Time. See "Calgene II--Directors and Executive
Officers."
 
 Termination; Termination Payment
 
  The Reorganization Agreement is subject to termination: (i) by mutual
consent of the Calgene Board and the Monsanto Board of Directors (the
"Monsanto Board"); (ii) by either the Calgene Board or the Monsanto Board if
the Merger is not consummated before March 31, 1996, unless such failure to
consummate shall be due to the failure of the party seeking to terminate the
Reorganization Agreement to perform in all material respects each of its
obligations under the Reorganization Agreement; (iii) by the Calgene Board or
the Monsanto Board in the event that the Calgene Board shall withdraw or
change its recommendation to its stockholders to adopt and approve the
Reorganization Agreement or authorize the Merger or if the approval of
Calgene's stockholders is not obtained; and (iv) upon the occurrence of
certain other events. If the Reorganization Agreement is terminated under
certain circumstances and Calgene consummates a similar transaction with a
party other than Monsanto within 12 months thereafter, Calgene must pay
Monsanto a termination fee in cash equal to $7.5 million. See "The
Reorganization Agreement and Related Agreements--The Reorganization
Agreement--Termination; Termination Fees."
 
RELATED AGREEMENTS
 
 Calgene Subordinated Promissory Note
 
  Pursuant to the terms of a subordinated promissory note of Calgene in favor
of Monsanto, Calgene borrowed $10 million from Monsanto on June 29, 1995. The
original promissory note was amended and restated on September 27, 1995 (as
amended and restated, the "Amended Note") to permit Calgene to borrow an
additional $8 million. As of December 31, 1995, all $18 million of principal
was outstanding under the Amended Note.
 
  The Amended Note is due on June 30, 1997; provided, however, that if the
Reorganization is not consummated because (i) Calgene's stockholders fail to
approve the Merger Proposal or (ii) any of Monsanto's other conditions to
closing set forth in the Reorganization Agreement, to the extent such
conditions are within the control of Calgene, are not satisfied at or prior to
Closing, then the maturity date of the Amended Note shall be June 30, 1996. If
the Reorganization Agreement is terminated for any reason, the outstanding
principal and interest due under the Amended Note can be converted, subject to
certain limitations, at the option of Monsanto from and after 60 days
following such termination, into shares of Calgene Common Stock at a
conversion price equal to 85% of the average of the closing market prices of
Calgene Common Stock on the Nasdaq National Market during a specified period
prior to conversion. Based upon the last reported sales price of Calgene
Common Stock on the Nasdaq National Market on December 15, 1995 ($4.875 per
share), the conversion of the Amended Note in such an event, assuming no
portion of the Amended Note is repaid before such conversion, would result in
the issuance of approximately 4,343,891 shares of Calgene Common Stock to
Monsanto, or approximately 14% of the total number of shares of Calgene Common
Stock currently outstanding. Upon the Effective Time, the outstanding
principal amount due under the Amended Note shall be credited against the $30
million cash contribution to be made by Monsanto in connection with the
Reorganization. Interest on the Amended Note will cease accruing at the
Effective Time and all interest accrued prior to such time shall be waived by
Monsanto. See "The Reorganization Agreement and Related Agreements--Calgene
Subordinated Promissory Note."

 The Stockholders Agreement
 
  The Reorganization Agreement provides that, at the Effective Time, Monsanto
and Newco shall enter into a Stockholders Agreement (the "Stockholders
Agreement"), containing provisions relating to: (a) the composition of the
Boards of Directors of Newco, Calgene and TIA; (b) restrictions upon the
purchase of additional shares of Newco Common Stock by Monsanto; (c)
restrictions upon sales of shares of Newco Common Stock by Monsanto; (d)
rights of Monsanto to require the registration of shares of Newco Common Stock
under the Securities Act; (e) rights of Monsanto to participate in future
equity financings of Newco; and (f) requirements that certain actions of Newco
be approved by at least one Calgene designee and one Monsanto designee on the
Newco Board. See "The Reorganization Agreement and Related Agreements--The
Stockholders Agreement."
 
 Newco Credit Facility Agreement
 
  Upon the Effective Time, Newco and Monsanto shall enter into a revolving
credit facility agreement (the "Newco Credit Facility Agreement") pursuant to
which Monsanto, subject to certain terms and conditions, shall make, at the
request of Newco, three consecutive one-year subordinated loans of up to $15
million each to Newco for general corporate purposes, provided that not more
than $15 million may be outstanding at any time. Under certain circumstances,
the principal and interest due under such loans may be converted into shares
of Newco Common Stock. The agreement also contains a number of restrictions on
Newco and its subsidiaries. See "The Reorganization Agreement and Related
Agreements--Newco Credit Facility Agreement."
 
 Gargiulo Credit Facility Agreement
 
  Upon the Effective Time, Newco and Monsanto shall enter into a revolving
credit facility agreement (the "Gargiulo Credit Facility Agreement") pursuant
to which Monsanto, subject to certain terms and conditions, shall make a loan
of up to $40 million to Newco, the proceeds of which are to be used solely by
TIA. Gargiulo L.P. expects to borrow up to $40 million from Monsanto pursuant
to an amendment of an existing credit facility to acquire Collier Farms, to
support Gargiulo L.P.'s branded tomato strategy and to allow Gargiulo L.P. to
make an approximately $2 million payment to Monsanto pursuant to the
Development License Agreement dated December 23, 1992 (the "Development
Agreement"), which amounts will be converted into a loan under the Gargiulo
Credit Facility Agreement at the Effective Time. The balance of any future
borrowings under the Gargiulo Credit Facility Agreement shall be used by TIA
to implement the branded tomato strategy described below. The loan is
repayable out of a specified portion of the Cumulative Free Cash Flow (as
defined in the Gargiulo Credit Facility Agreement) of TIA or, if not repaid
within eight years, may be converted by Monsanto under certain circumstances
into shares of Newco Common Stock. Based solely upon the last reported sales
price of Calgene Common Stock on the Nasdaq National Market on December 15,
1995 ($4.875 per share), the conversion of the maximum principal amount
available to Newco under the Gargiulo Credit Facility ($40,000,000) would
result in the issuance of approximately 8 million shares of Newco Common Stock
to Monsanto, or approximately 13% of the total number of shares of Newco
Common Stock which will be outstanding immediately after the Effective Time.

Possible Conflicts of Interest" and "--Possible Need for Additional
Financing." The agreement also contains a number of restrictions on Newco and
its subsidiaries. The final terms of the Gargiulo Credit Facility Agreement
are subject to the approval of Gargiulo L.P.'s principal lender. See "The
Reorganization Agreement and Related Agreements--Gargiulo Credit Facility
Agreement."
 
 License Agreements
 
  As part of the Reorganization, Monsanto will license to Newco certain
technology pursuant to various license agreements and letter agreements
(collectively, the "License Agreements"). See "The Reorganization Agreement
and Related Agreements--License Agreements."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
  As discussed in more detail below under "Approval of the Merger--Certain
Federal Income Tax Consequences," Calgene has received an opinion of its legal
counsel that the exchange of Calgene Common Stock for Newco Common Stock in
the Merger will qualify as tax-free pursuant to Section 351 of the Internal
Revenue Code of 1986, as amended (the "Code").
 
ACCOUNTING TREATMENT
 
  The Merger will be accounted for under the purchase method of accounting in
accordance with generally accepted accounting principles, whereby the purchase
price will be allocated based on the fair value of the assets acquired and
liabilities assumed. Such allocation will be made based upon valuations that
have not been finalized. It is anticipated that a significant portion of the
purchase price will be allocated to in-process research and technology which
will result in a charge to Newco's statement of operations of approximately
$59.2 million in the fiscal quarter in which the Reorganization closes. The
amount of the estimated charge is based on a preliminary valuation and the
actual amount could vary significantly upon completion of the final valuation.
 
  In addition, Newco plans to consolidate certain of the personnel, facilities
and other assets of Calgene, currently operating as its CalFresh division
("CalFresh"), with those of Gargiulo L.P. and, if the Collier Transaction is
consummated, to integrate the tomato operations of Collier Farms. In
connection with such consolidation activities, Newco expects to close certain
duplicative facilities and to incur restructuring charges, including the
write-off of redundant intangibles, of approximately $8.5 million, which will
be recorded in the fiscal quarter in which the Reorganization closes.
 
  A significant effect of the purchase accounting will be to record a
significant amount of goodwill and other intangible assets which will result
in substantial amortization charges to the consolidated income of Newco over
the useful lives of such assets. The amount of such charges are estimated at
approximately $6.5 million per fiscal year for approximately 12 years;
however, actual charges could vary significantly in the event the underlying
assets are impaired or the related useful lives are less than currently
estimated. See "Unaudited Selected Pro Forma Combined Financial Data."
 
REGULATORY APPROVALS
 
  No state or federal regulatory approvals are required relating to the
Reorganization, other than (i) the pre-transaction filing and waiting period
requirements applicable to the Reorganization under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the "HSR Act"), (ii) the
effectiveness of the Registration Statement of which this Proxy
Statement/Prospectus is a part and (iii) compliance with applicable state
securities laws. See "Approval of the Merger--Regulatory Approvals."
 
  The Reorganization is subject to the requirements of the HSR Act, and the
rules and regulations thereunder, which provide that certain transactions may
not be consummated until certain required information and materials have been
furnished to the Antitrust Division of the Department of Justice (the
"Antitrust Division") and the Federal Trade Commission (the "FTC") and certain
waiting periods have expired or been terminated. Monsanto
 
                                      14
<PAGE>
 
filed its notification pursuant to the HSR Act in October 1995. (Calgene was
not obligated to submit an HSR notification). In November 1995, the Antitrust
Division extended the HSR waiting period on the proposed transactions by
issuance of a request for additional information to Monsanto pursuant to the
HSR Act. The Antitrust Division has also requested information from Calgene
pursuant to the Antitrust Civil Process Act. Both Monsanto and Calgene have
provided significant documentary and other information to the Antitrust
Division in response to these requests and continue to do so. Both companies
expect to be in substantial compliance with the requests they received in the
near future. The parties are continuing to work with the Antitrust Division to
resolve any remaining issues and believe that they will ultimately be able to
resolve the Antitrust Division's questions, if any, in a manner which will
permit the Reorganization to proceed. See "Approval of the Merger--Regulatory
Approvals."
 
COMPARISON OF STOCKHOLDER RIGHTS
 
  The rights of holders of Calgene Common Stock are substantially similar to
the rights of holders of Newco Common Stock, provided, however, that Monsanto
will have certain additional rights as a stockholder of Newco pursuant to the
Stockholders Agreement. See "Comparison of Stockholder Rights" and "The
Reorganization Agreement and Related Agreements--The Stockholders Agreement."
 
NO APPRAISAL RIGHTS
 
  Holders of Calgene Common Stock do not have rights of appraisal under the
Delaware General Corporation Law (the "Delaware Law") in connection with the
Reorganization. See "No Appraisal Rights."
 
EXCHANGE OF CERTIFICATES FOR CALGENE COMMON STOCK
 
  From and after the Effective Time, certificates evidencing shares of Calgene
Common Stock will be deemed for all purposes to represent an equivalent number
of shares of Newco Common Stock. CALGENE STOCKHOLDERS WILL NOT BE REQUIRED TO
SUBMIT THEIR CERTIFICATES IN CONNECTION WITH THE REORGANIZATION.
 
RISK FACTORS
 
  In considering the Merger Proposal, holders of Calgene Common Stock should
consider the risks set forth under "Risk Factors."

                                 RISK FACTORS
 
  The following risk factors should be considered by stockholders of Calgene
in evaluating whether to approve the Merger Proposal and thereby become
holders of Newco Common Stock. These factors should be considered in
conjunction with the other information included and incorporated by reference
in this Proxy Statement/Prospectus.
 
RISKS RELATING TO NEWCO
 
  Management and Coordination of Operations. The achievement of the
anticipated benefits of the Reorganization will depend in part upon whether
the businesses of Calgene and Gargiulo L.P. can be managed and coordinated in
an efficient and effective manner after the Effective Time, and there can be
no assurance that this will occur. The difficulties of managing and
coordinating the businesses of Calgene and Gargiulo L.P. may be increased by
the geographic separation of the organizations and their decentralized
managements. The coordination of the businesses of Calgene and Gargiulo L.P.
following the Reorganization may require the dedication of management
resources which may temporarily distract attention from the day-to-day
business of the combined companies. In addition, if the Collier Transaction is
consummated, Gargiulo L.P. will need to integrate the operations of Collier
Farms into its own operations, which may further distract the management of
Gargiulo L.P. from day-to-day operations. In connection with the Collier
Transaction, Gargiulo L.P. expects to incur approximately $20 million of
indebtedness in the form of a $10 million loan from Monsanto under an existing
credit facility and a $10 million purchase money note payable to Collier
Enterprises (the "Seller Note"), subject to reduction in the event Gargiulo
L.P. assumes certain obligations of Collier Enterprises. Gargiulo L.P.'s
ability to repay such indebtedness will depend, in part, on the successful
integration of the operations of Collier Farms into the operations of Gargiulo
L.P. and the success of the Collier Farms operations which are subject to the
same agribusiness risks as apply to Newco as described below.
 
  Accounting Treatment of Certain Reorganization Costs. It is anticipated that
a significant portion of the purchase price for Calgene will be allocated to
in-process research and technology, which will result in a charge to Newco's
statement of operations of approximately $59.2 million in the fiscal quarter
in which the Reorganization closes. The amount of the estimated charge is
based on a preliminary valuation and the actual amount could vary
significantly upon completion of the final valuation. In addition, Newco plans
to consolidate CalFresh with Gargiulo L.P. and, if acquired, the tomato
operations of Collier Farms. In connection with such consolidation activities,
Newco expects to close certain duplicative facilities and to incur
restructuring charges, including the write-off of redundant intangibles, of
approximately $8.5 million, which will be recorded in the fiscal quarter in
which the Reorganization closes.
 
  A significant effect of the purchase accounting will be to record a
significant amount of goodwill and other intangible assets which will result
in substantial amortization charges to the consolidated income of Newco over
the useful lives of such assets. The amount of such charges are estimated at
approximately $6.5 million per year for approximately 12 years; however actual
charges could vary significantly in the event the underlying assets are
impaired or the related useful lives are less than currently estimated. See
"Unaudited Selected Pro Forma Combined Financial Data."
 
  Separate Board of Directors and Management of TIA. Pursuant to the
Stockholders Agreement, the Board of Directors of TIA shall consist of Jeffrey
D. Gargiulo and his brother, John R. Gargiulo (who are both officers of
Gargiulo L.P.), Hendrik A. Verfaillie and Robert T. Fraley (who are senior
executives of Monsanto), Roger H. Salquist and Roderick N. Stacey (who are
presently officers of Calgene), and an additional director designated by Newco
and reasonably acceptable to both Monsanto and Jeffrey D. Gargiulo (as long as
he is a director). The Chairman of the Board and Chief Executive Officer of
TIA shall be Jeffrey D. Gargiulo as long as he is employed by TIA. See
"Related Party Transactions--Gargiulo Employment Agreement." The Board of
Directors of TIA shall appoint the other officers of TIA. The TIA Board of
Directors shall have the authority to operate the business of Gargiulo L.P.
within the confines of the annual operating plan and strategic plan approved
by the Newco Board. See "The Reorganization Agreement and Related Agreements--
The Stockholders Agreement."
 
                                      21
<PAGE>
 
  The separate Boards of Directors and management of TIA and Newco could
present possible conflicts of interest and managerial difficulties to the
extent that there are differences between actions proposed to be taken (or not
taken) by the TIA Board of Directors or management and the Newco Board of
Directors or management. Such conflicts of interest and managerial
difficulties could adversely affect the business and operations of Newco.
 
  Combination of Calgene and Gargiulo L.P. Tomato Businesses. After the
Effective Time, Newco plans to consolidate CalFresh with Gargiulo L.P. under
the management of TIA, and to close certain duplicative facilities. In
addition, if the Collier Transaction is consummated, Gargiulo L.P. will
acquire the right to lease up to 11,000 acres of farmland in southwest
Florida. In such event, certain of the farmland owned by Gargiulo L.P. in
Florida would no longer be necessary and it is likely TIA would attempt to
sell such farmland. At December 31, 1995, such farmland secured approximately
$4.0 million of mortgage indebtedness. If the Collier Transaction is
consummated, such farmland would also be used as security for the Seller Note.
There can be no assurance that TIA will be able to sell such farmland for an
amount that is sufficient to repay the indebtedness secured by such farmland,
if at all. Newco anticipates further consolidations, the financial impact of
which cannot be estimated at this time. There can be no assurance that Newco
will not encounter difficulties in integrating the businesses of CalFresh and
Gargiulo L.P. See "--Risks Applicable to the Branded Tomato Strategy" and
"Calgene, Inc.--Business of Calgene--Fresh Market Tomato."
 
  Significant Influence by Monsanto and Possible Conflicts of Interest. After
the Effective Time, Monsanto will own 49.9% of the outstanding shares of Newco
Common Stock and will have the right to designate four of the nine members of
the Newco Board. Monsanto shall have the right to designate additional
directors if and when its percentage ownership of Newco Common Stock
increases. In addition, certain actions may not be taken by Newco without the
approval of Monsanto. See "The Reorganization Agreement and Related
Agreements--The Stockholders Agreement." Also, Monsanto is obligated, subject
to certain terms and conditions, to lend up to $40 million to Newco to effect
the Collier Transaction, make an approximately $2 million payment to Monsanto
pursuant to the Development Agreement and fund the branded tomato strategy
described below, and up to $15 million annually for a period of three years to
Newco for general corporate purposes, although not more than $15 million may
be outstanding thereunder at any one time. The Gargiulo Credit Facility
Agreement and the Newco Credit Facility Agreement each contain various
covenants precluding Newco and its subsidiaries from taking certain actions
without the approval of Monsanto. Also, in the event of a default by Newco
under the Newco Credit Facility Agreement or the Gargiulo Credit Facility
Agreement, Monsanto has certain rights to convert the outstanding principal
and interest under such agreements into additional shares of Newco Common
Stock at the then market value of the Newco Common Stock, and any such
conversion could substantially dilute the ownership interest of other Newco
stockholders. It is possible that Monsanto's interest as a stockholder of
Newco may differ from its interest as a lender, and there can be no assurance
that actions taken by Monsanto pursuant to the exercise of its various rights
under the Stockholders Agreement, the Gargiulo Credit Facility Agreement and
the Newco Credit Facility Agreement will be in the best interests of all other
stockholders of Newco.
 
  Possible Need for Additional Financing. Newco expects that the cash
contribution to be made by Monsanto pursuant to the Reorganization Agreement,
together with the proceeds of the Newco Credit Facility Agreement, the
Gargiulo Credit Facility Agreement and other bank lines of credit expected to
be available to Newco after the Effective Time, will be sufficient to fund its
operations through at least the end of calendar 1996. However, such
expectation is based in part on the achievement of the operating plans of
Calgene and Gargiulo L.P. for the year ended June 30, 1996 ("Fiscal 1996"),
and there can be no assurance such operating plans will be achieved. If such
plans are not achieved, additional funds might be required by Newco within the
next 12 months. Also, there can be no assurance that all of Newco's expected
sources of funds will be available. Calgene currently has a $13.0 million line
of credit with Harris Bank (the "Harris Credit Facility"), and Gargiulo L.P.
currently has a $17.5 million line of credit with NationsBank. The Harris
Credit Facility, which was scheduled to expire on January 31, 1996, has been
extended until March 31, 1996. Either of these banks may require changes in
the terms of the Newco Credit Facility Agreement and/or the Gargiulo Credit
Facility Agreement, and, if the required changes cannot be accommodated, there
can be no assurance that such banks will continue to make these lines of
credit available after the Effective Time or, if such lines are not available,
that Newco will
 
                                      22
<PAGE>
 
be able to obtain alternative bank financing on favorable terms, if at all. As
of October 31, 1995, Calgene was not in compliance with certain financial
covenants under its credit agreement with Harris Bank. While Calgene has
obtained waivers of such defaults through March 31, 1996, there can be no
assurance that it will be in compliance with such covenants in the future or,
in the event it is not in compliance, that it will be able to obtain waivers
of any such covenants. At June 30, 1995, Gargiulo L.P. was not in compliance
with certain financial covenants in its credit agreement with NationsBank.
Gargiulo L.P. has received waivers under such covenants until June 30, 1996.
There can be no assurance that Gargiulo L.P. will be in compliance with such
covenants or other covenants in its credit agreement in the future or that, in
the event it is not in compliance, that it will be able to obtain waivers of
any such covenants. While Monsanto has agreed, pursuant to the Gargiulo Credit
Facility Agreement, to make a $40 million loan available to Newco, advances
under such loan are subject to the achievement of certain milestones, and are
to be used solely to fund the branded tomato strategy described below (other
than amounts used to finance any borrowings made by Gargiulo L.P. to finance
the Collier Transaction and to allow Gargiulo L.P. to make an approximately $2
million payment to Monsanto pursuant to the Development Agreement) and are
repayable out of specified portions of the cumulative free cash flow of TIA.
While Monsanto has agreed, pursuant to the Newco Credit Facility Agreement, to
advance up to $15 million annually to Newco for three consecutive years, not
more than $15 million may be outstanding thereunder at any one time and if
Newco were to elect to convert any portion thereof into shares of Newco Common
Stock in order to gain access to additional borrowings under the Newco Credit
Facility Agreement, the issuance of such additional shares will trigger
Monsanto's right under the Stockholders Agreement to designate two additional
directors of Newco and thus control the Newco Board of Directors. See
"Reorganization Agreement and Related Agreements--The Stockholders Agreement."
Except as described above, Monsanto has no obligation to loan or otherwise
contribute additional cash to Newco. For all the foregoing reasons, there can
be no assurance that Newco will be able to obtain any future required
financing on favorable terms, if at all.
 
 History of Losses; Uncertainty of Future Financial Results. Calgene has
incurred aggregate net losses of approximately $188 million from inception in
1981 through September 30, 1995, including research and development expenses
in excess of $129 million. The net loss for Calgene in the year ended June 30,
1995 ("Fiscal 1995") was $30.6 million and was $10.4 million in the fiscal
quarter ended September 30, 1995. Calgene expects to incur a substantial net
loss in Fiscal 1996. Gargiulo L.P. experienced a net loss in the amount of
$1.7 million for Fiscal 1995, and incured a net loss of approximately $5.4
million for the fiscal quarter ended September 30, 1995. In addition, Collier
Farms incurred a net loss of approximately $341,000 during Fiscal 1995 and a
net loss of $1.7 million in the first quarter of Fiscal 1996. There is no
assurance that some or all of the factors which caused these historical losses
will not be present in future periods or that Calgene or Gargiulo L.P. will be
able to overcome these or other problems and achieve profitability in the
highly unpredictable and volatile fresh produce business. Newco's ability in
future years to reduce losses and operate at a profit will depend on, among
other things, (i) the successful integration and profitability of the fresh
produce operations of CalFresh, Gargiulo L.P. and, if acquired, Collier Farms,
(ii) the successful development by Calgene of its genetically engineered
products and (iii) the success of the branded tomato strategy described below.
There can be no assurance that Newco will achieve profitability in the future.
 
 Risks Associated with the Branded Tomato Strategy. Newco intends to combine
the premium quality branded tomato development program of Calgene, which
operates under the MacGregor brand name, and Gargiulo L.P., which operates
under the Gargiulo brand name, as part of its branded tomato strategy. This
strategy involves a number of risks to Newco, including, without limitation,
the following:
 
  Potential Inability to Successfully Produce or Market the Branded Tomato. A
branded tomato program requires year-round production of a tomato which
consistently and uniformly combines the characteristics and attributes retail
consumers generally look for in the tomatoes they purchase, such as pleasing
flavor, tempting color, and good size, shape and firmness. Newco believes that
such tomatoes, if successfully produced and marketed, would gain brand
recognition and that a sufficient number of retail consumers would be willing
to pay a premium price for such tomatoes.
 
 
                                      23
<PAGE>
 
  To date, no grower or shipper has successfully produced and supplied a
branded tomato on a nationwide and year-round basis. While Newco believes the
development of a successful branded tomato program is achievable, it
recognizes that such development will take a significant amount of time,
effort and capital.
 
  The difficulties in producing a branded tomato, whether or not genetically
engineered, include variability of weather conditions during any particular
growing season and the non-uniformity of other factors affecting tomatoes,
such as various crop diseases and pestilence. To supply a branded tomato year
round, tomatoes must be grown in different geographic locations. The
difference in locations also makes it difficult to produce tomatoes that
consistently taste, look and feel alike.
 
  Funding of Branded Tomato Strategy. Upon the terms and conditions of the
Gargiulo Credit Facility Agreement, Monsanto will make available to Newco a
revolving credit facility of up to $40 million. The proceeds of loans under
the Gargiulo Credit Facility Agreement are to be used solely to support the
branded tomato strategy (other than amounts used to finance up to $10 million
of borrowings made by Gargiulo L.P. to finance the Collier Transaction and to
allow Gargiulo L.P. to make an approximately $2 million payment to Monsanto
pursuant to the Development Agreement). In order to obtain an advance from
Monsanto under the Gargiulo Credit Facility Agreement, Newco must provide
reasonably acceptable documentation to Monsanto verifying that certain
milestones have been reached and certain goals have been achieved, all as set
forth in the Gargiulo Credit Facility Agreement. In the event such milestones
and goals are not achieved, Monsanto will have no obligation to make advances
under the Gargiulo Credit Facility Agreement and Newco will likely be unable
to obtain sufficient capital to support the implementation or expansion of the
branded tomato program.
 
  Significant Costs Associated with the Development of the Branded Tomato. In
order to implement the branded tomato strategy, Newco may be compelled to
expand current farming operations, as well as incur significant marketing
costs to achieve brand recognition. Gargiulo L.P. has already spent
significant amounts on marketing, including the hiring of a number of
marketing personnel and the performance of marketing surveys. Expenses for
other items such as advertising will be required to implement the branded
tomato program.
 
  Possible Unwillingness of Consumers to Pay Premium Prices for Branded
Tomatoes. Even if Newco is able to produce tomatoes suitable for a branded
program, there can be no assurance that retail consumers will be willing to
consistently pay premium prices for such tomatoes.
 
  Little Consumer Marketing Experience. Because Gargiulo L.P. has been
principally engaged in the commodity tomato business, and Calgene has little
experience in the fresh tomato business, Newco will have little or no
marketing experience of the type required for a branded tomato program.
Although Gargiulo L.P. has hired, and Newco intends to hire, employees with
such marketing experience, there can be no assurance that Newco's marketing
efforts will be successful. See "Tomato Investment Associates, Inc.--Gargiulo
L.P.--Marketing, Sales and Distribution."
 
 Risks Associated with Production of Genetically-Engineered Tomatoes. Calgene
has experienced difficulties in scaling-up production of its genetically-
engineered tomatoes and plans to temporarily curtail its tomato growing
operations in the Spring of 1996 until it is able to complete its development
of varieties with suitable agronomic characteristics. See "Calgene, Inc.--
Business of Calgene." There can be no assurance that Newco will be able to
accomplish such development or production scale-up of genetically-engineered
tomatoes. Unless and until such time as Newco develops genetically-engineered
tomatoes with agronomic characteristics which it deems sufficient for cost-
effective commercial production, it will be dependent upon the sale of
tomatoes into the commodity markets.
 
 Agribusiness Risks. A variety of agribusiness risks affect all of the fresh
produce sold by Calgene, Gargiulo L.P and Collier Farms, including, without
limitation, the following:
 
  Supply and Demand. The fresh produce business is particularly sensitive to
fluctuations in supply and demand. When the supply of tomatoes and berries in
the market exceeds the demand for such products, the market price for fresh
produce may be driven down significantly, in some instances below the cost of
harvesting and packing. In such situations it may be uneconomical to harvest a
crop, resulting in a total loss of the costs
 
                                      24
<PAGE>
 
incurred in growing such crop. Even when market prices are sufficient to
permit recovery of direct harvesting and packing costs, prices may not be high
enough to permit recovery of growing costs and/or overhead and other indirect
costs. In addition, oversupply can also affect the prices obtained for premium
quality produce. See "--Risks Associated with the Branded Tomato Strategy."
 
  Limited Barriers to Entry. The relatively low capital requirements for
farming permit relatively easy entrance into the fresh produce business, which
in turn can result in over-supply.
 
  Weather. Weather conditions greatly affect the amount of fresh produce that
is brought to market, and, accordingly, the prices received for such produce.
Storms, frosts, droughts, and particularly floods, can destroy a crop and less
severe weather conditions, such as excess precipitation, cold weather and
heat, can kill or damage significant portions of a crop, rendering much of it
unpackable and unsalable.
 
  Crop Disease and Pestilence. Crop disease and pestilence can be
unpredictable and can have a devastating effect on crops, rendering them
unsalable and resulting in the loss of all or a major portion of the crop for
that harvest season. Even when only a portion of the crop is damaged, the
profits a grower could have made on the crop will be severely disrupted
because the costs to plant and cultivate the entire crop will have been
incurred although only a portion of it can be sold. While some crop diseases
and pestilence are preventable or treatable, the costs of prevention or
treatment may be high. Both Calgene and Gargiulo L.P. are attempting to
develop insect and disease resistant strains of tomatoes, other produce and
cotton. However, there can be no assurance that these efforts will be
successful.
 
  Labor Shortages and Union Activity. The production of fresh produce is
heavily dependent upon the availability of a large migrant labor force in
order to harvest crops. The turnover rate among the migrant labor force is
high due to the strenuous work, long hours, necessary relocation and
relatively low pay. Further, the pool of such workers willing and able to do
such unskilled manual labor is shrinking. To the extent it becomes necessary
to pay more to attract unskilled labor to migrant farm work, labor costs can
be expected to increase. In addition, compliance with more stringent
immigration laws has increased and is likely to continue to increase migrant
labor costs.
 
  The migrant worker work force has not been unionized for the most part,
though significant efforts to form collective bargaining units or to have
existing ones recognized has occurred in the past, particularly in California
and, to a lesser extent, Southwest Florida. There can be no assurance that
such union organizing activities will not occur in the future. If such
organizing efforts were to occur and be successful on a large scale, labor
costs would likely increase and there could be work stoppages, which would be
particularly damaging in an industry where harvesting crops at peak times and
getting them to market on a timely basis is critical. The majority of fresh
produce is shipped by truck and is therefore susceptible to labor disturbances
in the trucking industry. Labor disturbances in the trucking industry can
limit the ability to get fresh produce to market before it spoils. Although
Gargiulo L.P. has never been affected by a nationwide truckers strike, it has
been affected by regional strikes and there can be no assurance that Newco
will not be affected by national or regional labor disruptions in the trucking
industry in the future.
 
  Availability of Farmland in Florida and California. Newco intends to lease
the majority of the land on which it grows its crops, particularly tomatoes.
These leases are generally short term, and as a result, Newco will likely be
required to renegotiate many of its leases on an annual basis, thereby
subjecting itself to the possibility of increased rental payments. In
addition, a significant amount of the available land in Florida is classified
as "wetlands" and subject to significant restrictions on use. While Newco
believes that the acquisition of Collier Farms by Gargiulo L.P. will reduce
this risk in part, there can be no assurance that the Collier Transaction will
be consummated or that Newco will enjoy the benefits it anticipates as a
result of the Collier Transaction. See "Tomato Investment Associates, Inc.--
Collier Farms."
 
  Risks similar to those set forth above are associated with the continued
leasing of farmland for the growing of strawberries in California.
Additionally, farmland along the California coast is subject to the problem of
salt water intrusion which would be adverse to the growing of strawberries.
 
 
                                      25
<PAGE>
 
  Seed Sales. Seed sales are affected by U.S. government agricultural policy,
which imposes varying limitations on planting acreage as a criterion for
farmers' eligibility to receive government subsidy payments and other
benefits. There is no assurance that current or future U.S. government
agricultural policies will not have a material adverse effect on Newco's
financial results.
 
  Technological Change. The application of recombinant DNA and related
technologies to plants is complex and subject to rapid change. A number of
companies are engaged in research related to plant biotechnology, including
companies that rely on the use of recombinant DNA as a principal scientific
strategy and companies that rely on other technologies. Technological advances
by others could render Newco's products less competitive. Many of these
companies, as well as competitors that supply non-genetically engineered
products, have substantially greater resources than Newco.
 
  Other companies are developing and seeking to commercialize premium quality,
fresh market tomatoes developed with recombinant DNA or other technologies.
One of Newco's competitors, a biotechnology company, has developed a vine-
ripened tomato using one such other technology, somoclonal variation, which it
is currently selling and it is also test-marketing a tomato developed using
recombinant DNA technology.
 
 Competition.
 
  Vegetables and Berries. The tomato and berry markets in which Newco intends
to compete are highly competitive. In addition to competition from other
domestic growers, many of whom have greater resources and are able to produce
at lower costs than Newco, there is increasing competition from foreign
producers, particularly Mexican growers who are able to compete both on the
basis of quality and price. The more arid climates in which the Mexican
tomatoes are grown are conducive to vine ripening. By contrast, the wetter
climates in which tomatoes are grown in the southeastern United States require
that they be picked while still green and exposed to ethylene gas to promote
ripening. Many retail consumers perceive vine ripened tomatoes to have better
flavor than standard "gas green" tomatoes. Accordingly, vine ripened tomatoes
produced in Mexico may be able to compete effectively against gas green
tomatoes which are the predominant product of Gargiulo L.P. and Collier Farms.
Although Gargiulo L.P. produces vine ripened tomatoes in Mexico and Puerto
Rico, such tomatoes represented only approximately 10% of Gargiulo L.P.'s
total tomatoes produced during Fiscal 1995. In addition, Gargiulo L.P.
believes that certain provisions in the North American Free Trade Agreement,
coupled with the sharp devaluation of the Mexican peso, are primarily
responsible for the below-production-cost prices that Florida tomato growers
received for their tomatoes last winter in the United States. Although
Gargiulo L.P. is not able to predict the financial effect which the surge of
Mexican tomatoes into the U.S. will have on its revenues, it expects that the
large supply, combined with the vine-ripening characteristics that some
consumers find more attractive than gas-green tomatoes, will continue to have
a significant adverse impact on the revenues of Florida tomato growers,
including Gargiulo L.P. Furthermore, in the event the branded tomato strategy
is successful, there can be no assurance that Newco's competitors, many of
whom have greater resources, will not be able to duplicate such strategy and
produce branded tomatoes for sale at premium prices. In such event, the
success of Newco's branded tomato strategy may be adversely affected. See "--
Risks Associated with the Branded Tomato Strategy."
 
  Cotton and other products. One competitor in the cotton seed market in which
Calgene competes, Delta and Pine Land Company, has a market share of
approximately 70%, compared with Calgene's market share of approximately 15%.
Monsanto has licensed its B.t. technology to Calgene and such other
competitor. However, B.t. technology must compete in a marketplace with the
competing technology of other established companies. See "The Reorganization
and Related Agreements--License Agreements." Competition is also intense in
the oleochemicals market, where Calgene competes with numerous companies.
 
 Dependence on Key Personnel. The success of Newco's business operations will
be materially dependent upon the continued services of certain key personnel
of Calgene, including Roger H. Salquist, and certain key personnel of Gargiulo
L.P., including Jeffrey D. Gargiulo and Robert Shulman. The loss of any key
personnel due to death, disability or termination of employment could have a
material adverse impact on the operations or financial condition of Newco.
Newco does not have key person life insurance covering its senior management
personnel.
 
 
                                      26
<PAGE>
 
 Dependence on Certain Corporate Relationships. Calgene and Gargiulo L.P. each
enjoy relationships with other companies which have contributed, and in some
cases continue to contribute, to their respective success. Newco's future
success will depend, in part, on developing new relationships and continuing
the existing relationships with these companies following the Reorganization,
their continued strategic interest in the development of certain of Calgene's
products and, eventually, their success in marketing such products or
increasing the willingness of consumers to purchase such products from Newco.
 
ADDITIONAL RISKS RELATING TO CALGENE
 
  Product Development Uncertainties. Although Calgene has completed the
genetic engineering of BXN(TM) cotton and laurate canola, Calgene's other
genetically engineered products are at various stages of development. There
are difficult scientific objectives to be achieved in certain product
development programs before the technological feasibility of such products can
be demonstrated. Even the more advanced programs could encounter technological
problems that could significantly delay or prevent product development or
product introduction.
 
  Patents and Trade Secrets. Since 1992, Calgene has been engaged in
litigation with Enzo Biochem, Inc. ("Enzo") a company licensed under three
related U.S. patents and counterpart foreign patents (the "Enzo Patents")
which purport to cover the use of antisense technology in all cells, including
plant cells. Some of Calgene's products, including the FLAVR SAVR tomato, use
antisense technology. Enzo claimed that Calgene infringed the Enzo Patents.
Calgene denied infringement and challenged the validity of the Enzo Patents.
On February 2, 1996, the District Court ruled that the Enzo Patents are
invalid. In addition, the validity of a patent owned by Calgene directed to
the use of antisense in plant cells was upheld by the District Court. Enzo has
indicated that it intends to appeal the decision. If on appeal a court were to
determine that one or more of the Enzo Patents validly covers plant cells and
that such patents are infringed by Calgene's sales of products incorporating
such antisense technology, Calgene could be held liable for significant
damages and could be precluded from producing and selling the FLAVR SAVR
tomato, as well as other products currently under development. There is no
assurance that a license, if necessary, could be obtained by Calgene on
commercially acceptable terms, if at all.
 
  The European Patent Office (the "EPO") has granted a patent to Enzo with
respect to claims which are intended to cover the use of antisense in all
cells, including plant cells. The EPO has also granted a patent to Agracetus,
Inc., a plant biotechnology company ("Agracetus"), with claims which are
intended to cover the use of antisense technology in all plants. A preliminary
decision from the EPO indicates that Calgene's opposition to Enzo's patent
should be rejected. Calgene has filed supplemental arguments with the EPO
responding to the EPO's reasoning and providing additional grounds for
invalidation based upon evidence which surfaced during the course of the U.S.
litigation and intends to supplement its opposition in the near future against
such Agracetus patent. If these proceedings are not successful in limiting the
scope of the claims of these patents and if Calgene is unable to obtain
licenses from the respective patent holders to use such antisense technology,
Calgene could be prevented from expanding some of Calgene's genetically
engineered products, including tomatoes engineered with the FLAVR SAVR gene,
into Europe. There is no assurance that licenses could be obtained on
commercially reasonable terms, if at all.
 
  Other companies have applied for patents covering B.t. technology. If
patents were to be issued to other companies, Calgene would be required to
obtain a license to employ the B.t. gene in commercial products. There is no
assurance that such licenses could be obtained on commercially reasonable
terms, if at all. Calgene has rights to obtain certain licenses to Monsanto's
B.t. technology and has licensed Plant Genetics Systems' issued B.t. patent.
 
  U.S. patents have been issued to Agracetus for the transformation of cotton.
Calgene has obtained a license from Agracetus for non-fiber uses. The patents
are now in reexamination before the U.S. Patent Office and some claims have
been indicated as allowable by the Examiner. Once the reexamination is
completed, Calgene may determine that a license under these patents is needed
for its genetically engineered cotton fiber products. There is no assurance
that such a license could be obtained on commercially reasonable terms, if at
all.
 
 
                                      27
<PAGE>
 
  A U.S. patent has been issued to a competitor for a genetic component which
is currently used in Calgene's FLAVR SAVR tomato. Although alternatives are
available, in the event Calgene would be prevented from utilizing this genetic
element, it would cause disruption in the production of FLAVR SAVR tomatoes.
Analysis of this patent is currently underway. In the event that it is
determined that a license is necessary, there is no assurance that a license
can be obtained on commercially reasonable terms, if at all.
 
  Patent applications filed in the United States are not publicly available
for examination. Patent applications filed outside of the United States may be
available for examination, but may not accurately reflect the applications
filed in the United States on the same claimed inventions. Patent applications
filed or to be filed in the future by Calgene's competitors or others could,
if patents are issued, preclude Calgene from using, in the patent issuing
countries, technology and techniques basic to genetic engineering and to areas
of particular importance to Calgene. If Calgene is unable to obtain licenses
to use such technology, there could be a delay in the introduction of some of
Calgene's genetically engineered products in those countries. Whether such
patents will be issued, the extent to which Calgene would be required to
license such patents and the availability and cost of such licenses are
currently unknown.
 
  Calgene has received U.S. and foreign utility patents and has filed and will
continue to file patent applications in order to obtain proprietary protection
of certain genes, gene constructs, uses of genes in specific applications and
methods for genetic engineering of plants. There is no assurance that future
patents can be obtained in a timely fashion or, if issued, will afford Calgene
significant protection. In addition to patents, Calgene seeks to protect its
proprietary know-how as trade secrets. Although Calgene takes precautionary
measures to maintain the confidentiality of its trade secrets, there is no
assurance that competitors will not gain access to Calgene's know-how or
independently develop substantially equivalent know-how.
 
  Public Acceptance of Genetically Engineered Products. The commercial success
of Calgene's genetically engineered products will depend in part on public
acceptance of the cultivation and consumption of genetically engineered plants
and plant products. Public attitudes may be influenced by claims that
genetically engineered plant products are unsafe for consumption or pose a
danger to the environment. There is no assurance that Calgene's genetically
engineered products, such as fresh market tomatoes and herbicide resistant
cotton, will gain public acceptance.
 
  Government Regulation. The field testing, production and marketing of
genetically engineered plants and plant products by Calgene is subject to
federal, state, local and foreign governmental regulation. There is no
assurance that regulatory agencies administering existing or future
regulations or legislation will allow Calgene to produce and market its
genetically engineered products in a timely manner or under technically or
commercially feasible conditions. In addition, regulatory action or private
litigation could result in expenses, delays or other impediments to Calgene's
product development programs or the commercialization of resulting products.
 
  Although the U.S. Food and Drug Administration (the "FDA") has announced in
a policy statement that it will apply the same regulatory standards to foods
developed through genetic engineering as applied to foods developed through
traditional plant breeding, genetically engineered food products will be
subject to premarket review if they raise safety questions or are deemed to be
food additives. In May 1994, the FDA announced its determination that the
FLAVR SAVR tomato has not been significantly altered with respect to safety or
nutritive value when compared to conventional tomatoes and also published a
food additive regulation allowing the use of the kanr marker gene in the
development of new varieties of tomato, cotton and canola. Calgene has
subsequently completed the safety assessment of its BXN(TM) cotton and laurate
canola products in accordance with the FDA policy. There is no assurance that
future Calgene products will not be subject to lengthy FDA reviews and
unfavorable FDA determinations if they raise safety questions or are deemed to
be food additives.
 
  The FDA has announced in a policy statement that it will not require that
genetically engineered products be labeled as such, provided that such
products are as safe, and have the same nutritional characteristics as
conventionally developed products. There can be no assurance that the FDA will
not reconsider its position, or
 
                                      28
<PAGE>
 
that local and state authorities will not enact labeling requirements, either
of which could have a material adverse effect on Calgene. In addition, the
Mexican health and agriculture authorities and Health Canada could reconsider
their respective positions regarding the marketing of the FLAVR SAVR tomato.
 
  The United States Department of Agriculture (the "USDA") prohibits
genetically engineered plants from being grown and transported except pursuant
to a deregulation, or under controls so burdensome as to render
commercialization impracticable. The only Calgene plants currently exempted by
the USDA are Calgene's initial tomato varieties engineered with the FLAVR SAVR
gene, the BXN(TM) cotton varieties and laurate canola. No assurance can be
given that additional Calgene products will be exempted by the USDA.
 
ADDITIONAL RISKS RELATING TO GARGIULO L.P.
 
  Ability to Continue to Lease Land from Affiliates. Much of the land leased
in southwest Florida to Gargiulo L.P. is owned by persons or entities which
possess or have possessed significant ownership interests in Gargiulo L.P. or
companies affiliated with Gargiulo L.P. Such persons and entities have been
motivated to lease such crop lands to Gargiulo L.P. to allow Gargiulo L.P. to
use it to produce crops and provide a return on their investments in Gargiulo
L.P. Upon consummation of the Reorganization, these individuals and entities
will no longer have a financial interest in Gargiulo L.P. and may be motivated
to lease lands owned by them to third parties willing to pay higher rental
payments or to sell such land to third parties who may not lease it to
Gargiulo L.P. While Gargiulo L.P. believes that the acquisition of Collier
Farms will reduce this risk, there can be no assurance that Collier Farms will
be acquired. See "Related Party Transactions."
 
  Early Stage and Uncertainty of Development of Gargiulo Genetically Altered
Produce. Gargiulo L.P. entered into a Development/License Agreement with
Monsanto dated as of December 23, 1992, for the purpose of developing
transgenic tomatoes with a longer shelf life for commercial application. The
research and development to date relating to transgenic tomatoes has not
yielded a tomato with a longer shelf life which can be produced on a
commercially feasible basis. Accordingly, Gargiulo L.P. believes that its
future earnings will be dependent on the success of its commodity tomato
business and its branded tomato program. There can be no assurance that
Gargiulo L.P. will develop any genetically altered fruit or vegetable products
for commercial applications at any time in the future.
 
  Repack Operations. Gargiulo L.P. operates a tomato repack operation in
Palmetto, Florida. The tomato repack business is highly competitive and
requires different operational skills than those needed to be a successful
grower and shipper. Many of Gargiulo L.P.'s competitors in the repack business
are more experienced and have long standing relationships with customers.
Gargiulo L.P.'s inability to operate the repack operation profitably
contributed to the loss Gargiulo L.P. experienced during Fiscal 1995. Gargiulo
L.P. intends to relocate its repack operation to Immokalee, Florida into a
facility it will lease from Calgene. Gargiulo L.P. will close and put up for
sale its Palmetto, Florida facility where its repack operation is currently
located. There can be no assurance that Gargiulo L.P. will be able to operate
a repack operation profitably in the future.

  Newco and Calgene have never declared or paid cash dividends and Newco does
not intend to pay cash dividends in the foreseeable future. Future cash
dividends, if any, will be determined by the Newco Board and will be based
upon Newco's future earnings, capital requirements, financial condition and
other factors deemed relevant by the Newco Board. In addition, the ability of
Newco to pay dividends would be restricted by the terms of certain
indebtedness of Calgene and Gargiulo L.P. which Newco intends to assume as of
the Effective Time, as well as the terms of the Newco Credit Facility
Agreement and the Gargiulo Credit Facility Agreement. See "The Reorganization
Agreement and Related Agreements--Newco Credit Facility Agreement" and "--

Common Stock in connection with the solicitation of proxies by the Calgene
Board for use at the Special Meeting and at any adjournment or postponement
thereof. Each copy of this Proxy Statement/Prospectus mailed to holders of
Calgene Common Stock is accompanied by a form of proxy for use at the Special
Meeting. This Proxy Statement/Prospectus and the accompanying form of proxy
(the "Calgene Proxy") are first being mailed on or about February 9, 1996.
 
  CALGENE STOCKHOLDERS ARE REQUESTED TO COMPLETE, SIGN AND DATE THE CALGENE
PROXY AND RETURN IT PROMPTLY IN THE ENCLOSED, POSTAGE-PAID ENVELOPE.
 
DATE, TIME AND PLACE
 
  The Special Meeting is scheduled to be held on Monday, March 25, 1996, at
the Varsity Theatre, 616 2nd Street, Davis, California, commencing at 9:00
a.m., local time.
 
MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING
 
  The purpose of the Special Meeting is to approve the Reorganization
Agreement, and the related Plan of Merger, under which Calgene and TIA will
each become a wholly-owned subsidiary of Newco, pursuant to: (i) a merger of a
wholly-owned subsidiary of Newco with and into Calgene and the conversion of
each outstanding share of Calgene Common Stock upon the Effective Time into
the right to receive one share of Newco Common Stock, followed immediately by
(ii) the exchange by Monsanto of all the outstanding shares of capital stock
of TIA, $30 million in cash (less amounts previously advanced to Calgene under
an existing subordinated promissory note, under which $18 million was
outstanding at December 31, 1995), and certain technology licenses, for that
number of shares of Common Stock representing 49.9% of the outstanding shares
of Newco Common Stock upon the Effective Time. Upon the Effective Time, Newco
will be renamed "Calgene, Inc." A vote in favor of the Merger Proposal shall
be deemed to be ratification of (i) the assumption by Newco of Calgene's 1991
Stock Option Plan, (ii) the assumption by Newco of Calgene's 1990 Employee
Stock Purchase Plan, (iii) the adoption of the Newco 1996 Stock Option Plan
and (iv) the election of the eight directors of Newco specified in this Proxy
Statement/Prospectus. See "Approval of the Merger--Interests of Certain
Persons in the Reorganization" and "Newco, Inc.--Directors and Executive
Officers."
 
 Calgene Board Recommendation
 
  The Calgene Board has unanimously approved the Reorganization Agreement and
the Merger Proposal and recommends a vote FOR approval of the Merger Proposal.
 
VOTING AT THE SPECIAL MEETING; RECORD DATE
 
  The Calgene Board has fixed January 25, 1996, as the record date for the
determination of Calgene stockholders entitled to notice of and to vote at the
Special Meeting. Accordingly, only holders of record of Calgene Common Stock
on the Record Date will be entitled to notice of and to vote at the Special
Meeting. As of the Record Date there were 30,264,257 shares of Calgene Common
Stock outstanding. Each holder of record of shares of Calgene Common Stock on
the Record Date is entitled to cast one vote per share, exercisable in person
or by properly executed proxy, at the Special Meeting. The presence, in person
or by properly executed proxy, of the holders of a majority of the outstanding
shares of Calgene Common Stock entitled to vote at the Special Meeting is
necessary to constitute a quorum at the Special Meeting.
 
  The approval of the Merger Proposal will require the affirmative vote of the
holders of a majority of the outstanding shares of Calgene Common Stock on the
Record Date.

                            APPROVAL OF THE MERGER
 
BACKGROUND OF THE REORGANIZATION
 
  Calgene has from time to time had discussions with other companies in an
effort to gain access to new markets for its biotechnology products and to
license new technologies. In the course of such discussions, Calgene has
considered possible alliances, combinations and other transactions with
various companies, including companies both smaller and larger than Calgene.
 
  In October 1994, Roger H. Salquist, Calgene's Chief Executive Officer,
contacted Hendrik A. Verfaillie, an Executive Vice President of Monsanto, and
inquired as to Monsanto's interest in exploring a strategic alliance with
Calgene. At a subsequent meeting, Messrs. Salquist and Verfaillie, and their
respective financial advisors, discussed the possibility of a strategic
alliance pursuant to which, among other things, Monsanto would acquire more
than a majority interest in a new joint venture that would be formed to own
and operate the businesses of Calgene and Gargiulo L.P., as well as certain
other Monsanto operations. From October 1994 through January 1995, there were
continued discussions between representatives of Calgene and Monsanto with
respect to the structure and terms of such an alliance. In addition,
representatives of Monsanto conducted diligence with respect to the operations
of Calgene, and representatives of Calgene conducted diligence with respect to
the operations of Gargiulo L.P. Monsanto and Calgene were ultimately unable to
reach agreement as to the terms and structure of the proposed strategic
alliance, and in early February 1995 the parties determined to terminate all
discussions with respect to a possible strategic alliance.
 
  In May 1995, Messrs. Salquist and Verfaillie had discussions concerning a
possible strategic alliance pursuant to which Monsanto would contribute
certain cash, technology and the equity interests in Gargiulo L.P. to Calgene
in exchange for an ownership interest in Calgene. The parties determined that
Monsanto would acquire an approximately 49% interest in Calgene after
negotiations that involved consideration of the specific businesses and
technologies and the amount of cash that would be contributed by Monsanto. In
view of the parties' previous inability in late 1994 to agree on the value of
certain non-tomato operations that Monsanto had proposed to contribute to the
alliance, it was agreed that such non-tomato operations would not be part of
the transaction.
 
  At a special meeting of the Calgene Board on May 22, 1995, Mr. Salquist
reviewed the status of discussions regarding the potential strategic alliance
with Monsanto. The Calgene Board authorized Mr. Salquist to proceed with
negotiations concerning such a possible strategic alliance.
 
  Representatives of Calgene and Monsanto then began discussions concerning
the terms and structure of the proposed alliance. In June 1995, there were
several meetings between various members of management of Calgene, Monsanto
and Gargiulo L.P. to discuss various management and integration issues.
 
  On June 26, 1995, at a meeting of the Calgene Board, the directors of
Calgene reviewed the status of discussions and the principal terms of the
proposed transaction. The Calgene Board authorized Calgene to enter into a
letter of intent with respect to the proposed transaction.
 
  On June 27, 1995, Calgene and Monsanto entered into a letter of intent, and
a press release was issued with respect to such letter of intent.
 
  From July 27 through October 4, 1995, Calgene and Monsanto, and their
respective legal counsel, negotiated the terms of the Reorganization Agreement
and related agreements. Calgene continued its diligence review of Gargiulo
L.P., and Monsanto continued its diligence review of Calgene.
 
  On October 5, 1995, a meeting of the Calgene Board was held to consider the
Reorganization Agreement. Representatives of Montgomery attended and presented
their oral opinion which was subsequently confirmed in writing as of such
date, as to the fairness of the consideration to be received by Newco in
exchange for 49.9% of the Newco Common Stock, from a financial point of view
as of such date. The Calgene Board, acting on the recommendation of Calgene's
management and in view of the fairness opinion of Montgomery, approved the
Reorganization Agreement and the transactions contemplated thereby.
 
                                      33
<PAGE>
 
  On October 13, 1995, Calgene and Monsanto executed the Reorganization
Agreement. Prior to Closing, Newco, Sub, Calgene and Monsanto will execute a
joinder agreement, the primary purpose and effect of which will be to bind
Newco and Sub, which were not incorporated at the time the Reorganization
Agreement was executed, to the Reorganization Agreement. See "The
Reorganization Agreement and Related Agreements --Joinder Agreement."
 
CALGENE'S REASONS FOR THE REORGANIZATION; RECOMMENDATION OF THE CALGENE BOARD
OF DIRECTORS
 
  The Calgene Board recommends that the holders of Calgene Common Stock
approve the Merger Proposal and the Reorganization Agreement and vote FOR the
approval of the Merger Proposal for the reasons set forth below.
 
  Gargiulo L.P. provides Newco with a diversified base for the production and
marketing of large volumes of high-quality fresh market tomatoes. Calgene has
incurred considerable losses due primarily to the difficulty in scaling up
production of its MacGregor brand tomato. It is expected that Gargiulo L.P.'s
production and marketing infrastructure will enable Newco to significantly
reduce its unit costs and expand sales volumes of high-quality, premium-priced
branded tomatoes. Gargiulo L.P. also provides Newco with a platform upon which
to build a diversified branded produce business, including strawberries and
other fresh produce.
 
  Gargiulo L.P. also provides Newco with superior tomato germplasm into which
the FLAVR SAVR gene and other genetically engineered traits can be
incorporated. BHN, Gargiulo L.P.'s tomato breeding subsidiary, has developed
proprietary, high-yielding, flavorful tomato hybrid varieties that can be
engineered with the FLAVR SAVR gene, if Newco determines that such gene can
enhance the value of its branded tomatoes.
 
  Calgene believes that the technology licenses to be contributed by Monsanto
may enable Newco to develop a portfolio of genetically engineered products.
Monsanto and Calgene have developed complementary technologies in the areas of
ripening control, virus and insect resistance, fungal disease resistance and
carbohydrate metabolism that may be applied to Gargiulo L.P.'s core tomato and
strawberry product lines in order that Newco may evaluate the market potential
and commercial feasibility of such products. In addition, Monsanto's plant
oils-related technology is expected to improve the stability and decrease the
unit cost of several of Calgene's genetically modified oil products. Calgene
recognizes, however, that any commercially valuable exploitation of such
technology will only be realized over the long term and there can be no
assurance that any commercially valuable exploitation will ever be realized.
 
  The significant operating losses incurred by Calgene in developing and
producing its genetically-engineered tomatoes have created the need for
significant amounts of capital, and there can be no assurance that Calgene
would have been able, absent the transaction with Monsanto, to obtain the
financing needed to fund its operations through the end of calendar 1995. As
part of the Reorganization, Monsanto has provided, and will provide, Calgene
with substantial financial resources. Monsanto will contribute $30 million to
Newco upon the Effective Date ($18 million of which will have been previously
provided to Calgene in the form of a convertible note), a $40 million
subordinated revolving credit facility which will primarily be used to fund
the branded tomato strategy, and a three-year $15 million subordinated
revolving credit facility that can be used for general corporate purposes,
although not more than $15 million may be outstanding thereunder at any time.
 
BENEFITS AND DETRIMENTS OF THE REORGANIZATION TO CALGENE
 
  Possible benefits and detriments of the Reorganization to Newco and Calgene
and to the stockholders of Newco (other than Monsanto) include the following:
 
  BENEFITS
 
  .  Gargiulo L.P. provides Newco and Calgene with a diversified base and a
     strong infrastructure for the production and marketing of large volumes
     of high-quality fresh market tomatoes.
 
  .  Gargiulo L.P. provides Newco with superior tomato germplasm.
 
                                      34
<PAGE>
 
  .  The technology to be licensed by Monsanto may enable Newco to develop a
     portfolio of new genetically engineered products and to improve Calgene's
     genetically modified oil products.
 
  .  The cash to be invested and loaned by Monsanto is expected to enable
     Calgene to continue to fund its operations through the end of 1996.
     Absent the initial advance of $18 million by Monsanto and its commitment
     for additional funds, it is uncertain whether Calgene would have been
     able to fund its operations through the end of 1995 or to obtain the
     waivers that it has obtained from its bank for certain covenant defaults
     under its bank credit agreement. See "Risk Factors--Risks Relating to
     Newco--Possible Need for Additional Financing."
 
  DETRIMENTS
 
  .  There can be no assurance that the expected benefits of the combination
     of the Calgene and Gargiulo L.P. tomato businesses will be realized or
     that the tomato operations of Gargiulo L.P., which are significantly
     larger than those of Calgene, will not expose Newco to greater financial
     risks if such operations encounter difficulties.
 
  .  Monsanto will be able to exert significant influence over Newco and
     Calgene by virtue of its rights, among other things, to designate certain
     members of the Newco Board. See "The Reorganization Agreement and Related
     Agreement--The Stockholders Agreement."
 
  .  The separate Boards of Directors and management of TIA and Newco could
     present possible conflicts of interest and managerial difficulties. See
     "Risk Factors--Risks Relating to Newco--Separate Board of Directors and
     Management of TIA."
 
OPINION OF CALGENE'S FINANCIAL ADVISOR
 
  Pursuant to an engagement letter dated January 18, 1995 (the "Engagement
Letter"), Calgene retained Montgomery as its financial advisor in connection
with the consideration by the Calgene Board of a possible transaction with
Monsanto or an affiliated entity. Montgomery is a nationally recognized firm
and, as part of its investment banking activities, is regularly engaged in the
valuation of businesses and their securities in connection with merger
transactions and other types of acquisitions, negotiated underwritings,
secondary distributions of listed and unlisted securities, private placements
and valuations for corporate and other purposes. Calgene selected Montgomery
as its financial adviser on the basis of its experience and expertise in
transactions similar to the Reorganization and its reputation in the
biotechnology and investment communities.
 
  At the October 5, 1995, meeting of the Calgene Board, Montgomery delivered
its oral opinion, subsequently confirmed in writing as of such date, that the
consideration to be received by Newco in exchange for 49.9% of the Newco
Common Stock pursuant to the Reorganization Agreement, consisting of all of
the capital stock of TIA, plus certain intellectual property and research and
development assets (the "R&D Assets") and a combination of cash and
forgiveness of debt in the aggregate amount of $30 million (the "Cash"), was
fair to Calgene, from a financial point of view, as of such date. No
limitations were imposed by Calgene on Montgomery with respect to the
investigations made or procedures followed in rendering its opinion.
 
  THE FULL TEXT OF MONTGOMERY'S WRITTEN OPINION TO THE CALGENE BOARD IS
ATTACHED HERETO AS ANNEX C AND IS INCORPORATED HEREIN BY REFERENCE, AND SHOULD
BE READ CAREFULLY AND IN ITS ENTIRETY IN CONNECTION WITH THIS PROXY
STATEMENT/PROSPECTUS. THE FOLLOWING SUMMARY OF THE MONTGOMERY OPINION IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE MONTGOMERY
OPINION. THE MONTGOMERY OPINION IS ADDRESSED TO THE CALGENE BOARD ONLY AND
DOES NOT CONSTITUTE A RECOMMENDATION TO ANY CALGENE STOCKHOLDER AS TO HOW SUCH
STOCKHOLDER SHOULD VOTE AT THE SPECIAL MEETING. IN FURNISHING ITS OPINION,
MONTGOMERY DID NOT ADMIT THAT IT IS AN EXPERT WITHIN THE MEANING OF THE TERM
"EXPERT" AS USED IN THE SECURITIES ACT AND THE RULES AND REGULATIONS
PROMULGATED THEREUNDER, OR THAT ITS OPINION CONSTITUTES A REPORT OR VALUATION
WITHIN THE MEANING OF SECTION 11 OF THE SECURITIES ACT AND THE RULES AND
REGULATIONS PROMULGATED THEREUNDER, AND STATEMENTS TO SUCH EFFECT ARE INCLUDED
IN THE TEXT OF THE MONTGOMERY OPINION.
 
                                      35
<PAGE>
 
  In connection with its opinion, Montgomery, among other things: (i) reviewed
certain publicly available financial and other data with respect to Calgene,
including Calgene's consolidated financial statements for recent years and
interim periods to June 30, 1995 and certain other relevant financial and
operating data relating to Calgene and Gargiulo L.P. made available to
Montgomery from published sources and from the internal records of Calgene,
Gargiulo L.P. and Monsanto, including Gargiulo L.P.'s consolidated financial
statements for recent years and interim periods to June 30, 1995; (ii)
reviewed the September 29, 1995 draft of the Reorganization Agreement provided
to Montgomery by Calgene; (iii) reviewed certain historical market prices and
trading volumes of Calgene Common Stock on the Nasdaq National Market; (iv)
analyzed the financial impact that the transactions contemplated by the
Reorganization Agreement are expected to have on the projected results of
Calgene; (v) reviewed and discussed with representatives of the management of
Calgene, Gargiulo L.P. and Monsanto certain information of a business and
financial nature regarding Calgene and Gargiulo L.P., furnished to Montgomery
by them, including financial forecasts and related assumptions of Calgene and
Gargiulo L.P.; (vi) made inquiries regarding and discussed the Reorganization
Agreement and other matters related thereto with Calgene's legal counsel; and
(vii) performed such other analyses and examinations as Montgomery deemed
appropriate.
 
  In connection with its review, Montgomery relied upon the accuracy and
completeness of the foregoing information and did not assume any
responsibility independently to verify such information. With respect to the
financial projections for Calgene and Gargiulo L.P. provided to Montgomery by
the management of Calgene and Monsanto, respectively, Montgomery assumed for
purposes of its opinion that they were reasonably prepared on bases reflecting
the best available estimates and judgments of their respective managements at
the time of preparation as to the future financial performance of Calgene and
Gargiulo L.P. and that they provided a reasonable basis upon which Montgomery
could form its opinion. Neither Calgene nor Monsanto publicly discloses
internal management projections of the type provided to Montgomery in
connection with Montgomery's review of the transactions contemplated by the
Reorganization Agreement. Such projections were not prepared with a view
toward public disclosure. In addition, such projections were based upon
numerous variables and assumptions that are inherently uncertain, including,
without limitation, factors related to general economic and competitive
conditions. Accordingly, actual results could vary significantly from those
set forth in such projections. Montgomery has assumed no liability for such
projections. Montgomery also assumed that there were no material changes in
Calgene's, Gargiulo L.P.'s or TIA's assets, financial condition, results of
operations, business or prospects since the respective dates of the last
financial statements made available to Montgomery, except for Gargiulo L.P.'s
proposed acquisition of Collier Farms. Montgomery relied on advice of counsel
and independent accountants to Calgene as to all legal and financial reporting
matters with respect to Calgene and the Reorganization Agreement. Montgomery
assumed that the parties will consummate the transactions contemplated by the
Reorganization Agreement in a manner that complies in all respects with the
applicable provisions of the Securities Act and the Exchange Act and all other
applicable federal and state statutes, rules and regulations. Montgomery
further assumed, with Calgene's consent, that the transactions contemplated by
the Reorganization Agreement will be consummated in accordance with the terms
described in the Reorganization Agreement, without any amendments thereto, and
without waiver by Calgene or Monsanto of any of the conditions to their
respective obligations thereunder. In addition, Montgomery did not assume
responsibility for making an independent evaluation, appraisal or physical
inspection of the assets or liabilities (contingent or otherwise) of Calgene,
Gargiulo L.P. or TIA, nor was Montgomery furnished with any such appraisals.
Further, the Montgomery Opinion was based on economic, monetary and market
conditions existing as of October 5, 1995.
 
  Montgomery provided financial advice to the management of Calgene in
connection with the structuring and negotiation of the Reorganization but made
no recommendation as to the form or amount of the consideration to be paid by
Monsanto in the Reorganization.

<PAGE>
 
  Set forth below is a brief summary of the report presented by Montgomery to
the Calgene Board on October 5, 1995, in connection with its opinion.
 
  Discounted Cash Flow Analysis--Operations. Montgomery performed a discounted
cash flow analysis of the projected cash flow of Calgene on a stand-alone
basis and pro forma to reflect the acquisition of Gargiulo L.P. and receipt of
the cash from Monsanto, but not the acquisition of the R&D Assets (analyzed
separately below), through calendar year 2000. Key assumptions in the
discounted cash flow analysis included discount rates of 20% to 25% for
Calgene as a stand-alone entity and 17.5% to 22.5% for the pro forma entity,
terminal multiples of projected earnings before interest and taxes ("EBIT") of
9.0x to 12.0x, and, in the stand-alone-analysis, the sale by Calgene of
4,000,000 shares of Calgene Common Stock to raise $20,000,000 to fund expected
operating losses. Utilizing these projections and assumptions, Montgomery
determined that the implied Calgene pro forma valuation was accretive to the
Calgene stand-alone valuation by a range of $1.36 to $2.42 per share. The
above analysis assumed the acquisition of Collier Farms by Gargiulo L.P.
Montgomery also performed a discounted cash flow analysis of the projected
incremental cash flow derived from the acquisition of Collier Farms. Key
assumptions in the analysis included discount rates of 15% to 20% and terminal
multiples of EBIT of 6.0x to 9.0x. Utilizing these projections and
assumptions, Montgomery determined that the incremental Collier Farms value
ranged from a low of $0.16 per share on a pro forma basis (based upon a
terminal multiple of 2000 EBIT of 6.0x and a discount rate of 20%) to a high
of $0.37 per share on a pro forma basis (based upon a terminal multiple of
2000 EBIT of 9.0x and a discount rate of 15%).
 
  Discounted Cash Flow Analysis--R&D Assets. Montgomery also performed a
discounted cash flow analysis of the projected cash flow of the R&D Assets
through calendar year 2006, applying discount rates for various R&D Asset
categories ranging from 20% to 50%. Utilizing these projections and
assumptions, Montgomery determined that the implied valuation for the R&D
Assets was $28.8 million, or $0.48 per share on a pro forma basis.
 
  Dilution Analysis. Using estimates prepared by Calgene and Gargiulo L.P.
management, Montgomery compared the estimated fiscal year 1996, 1997 and 1998
earnings (loss) per share of Calgene Common Stock on a stand-alone basis to
the estimated fiscal year 1996, 1997 and 1998 earnings (loss) per share of the
common stock of the pro forma combined companies, including for this purpose
Gargiulo L.P. and the receipt of the Cash from Monsanto but not the R&D
Assets. Based on such analysis, the proposed transaction would be accretive to
Calgene's estimated loss per share by $0.11 per share in 1996, and accretive
to Calgene's estimated earnings per share by $0.10 per share in 1997 and $0.11
per share in 1998. Montgomery performed the same analysis assuming no
acquisition of Collier Farms, which resulted in accretion to estimated
loss/earnings per share of $0.06, $0.05 and $0.05, respectively.
 
  Contribution Analysis. Montgomery analyzed the contribution of each of
Calgene and Gargiulo L.P. to the projected revenues and EBIT of the pro forma
combined companies for fiscal years 1996, 1997 and 1998. This analysis showed,
among other things, that based on pro forma combined income statements for the
combined companies, Calgene would have contributed 32.9%, 37.6% and 43.2% of
the total revenues and (not material), 16.0% and 39.7% of the EBIT,
respectively, of the combined companies in the periods described above.
Pursuant to the terms of the Reorganization Agreement, at the closing, Calgene
stockholders will own 50.1% of Newco. Montgomery also performed the above
analysis assuming no acquisition of Collier Farms. In that scenario, Calgene
would have contributed 37.0%, 41.1% and 46.3% of the total revenues and (not
material), 23.2% and 47.9% of the EBIT, respectively, of the combined
companies in the periods described above.
 
  Calgene Financial Issues. Montgomery discussed the significant losses
incurred by Calgene in recent periods as a result of difficulties in tomato
production, Calgene's weak cash position in relation to its ongoing losses,
Calgene's depressed stock price and the difficulties faced by Calgene in
accessing the financial markets on acceptable terms.
 
  The summary set forth above does not purport to be a complete description of
the presentation by Montgomery to the Calgene Board or the analyses performed
by Montgomery. The preparation of a fairness opinion is not necessarily
susceptible to partial analysis or summary description. Montgomery believes
that its
 
                                      37
<PAGE>
 
analyses and the summary set forth above must be considered as a whole and
that selecting portions of its analyses and of the factors considered, without
considering all analyses and factors, would create an incomplete view of the
process underlying the analyses set forth in its presentation to the Calgene
Board. In addition, Montgomery may have given various analyses more or less
weight than other analyses, and may have deemed various assumptions more or
less probable than other assumptions, so that the ranges of valuations
resulting from any particular analysis described above should not be taken to
be Montgomery's view of the actual value of Calgene or the combined companies.
The fact that any specific analysis has been referred to in the summary above
is not meant to indicate that such analysis was given greater weight than any
other analysis.
 
  In performing its analyses, Montgomery made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of Calgene, Gargiulo L.P.
or Monsanto. The analyses performed by Montgomery are not necessarily
indicative of actual values or actual future results, which may be
significantly more or less favorable than suggested by such analyses. Such
analyses were prepared solely as part of Montgomery's analysis of the fairness
of the transactions contemplated by the Reorganization Agreement to Calgene
and were provided to the Calgene Board in connection with the delivery of the
Montgomery Opinion. The analyses do not purport to be appraisals or to reflect
the prices at which a company might actually be sold or the prices at which
any securities may trade at the present time or at any time in the future.
Montgomery used in its analyses various projections of future performance
prepared by the managements of Calgene and Gargiulo L.P. The projections are
based on numerous variables and assumptions which are inherently unpredictable
and must be considered not certain of occurrence as projected. Accordingly,
actual results could vary significantly from those set forth in such
projections.
 
  As described above, the Montgomery Opinion and the presentation to the
Calgene Board were among the many factors taken into consideration by the
Calgene Board in making its determination to approve the transactions
contemplated by the Reorganization Agreement.
 
  Pursuant to the Engagement Letter, Calgene engaged Montgomery to act as its
financial advisor in connection with a possible transaction with Monsanto or
an affiliated entity. Calgene has agreed to pay Montgomery a fee equal to
0.85% of the total consideration contributed by Monsanto pursuant to the
Reorganization Agreement. Pursuant to the Engagement Letter, Calgene has
previously paid Montgomery $100,000, and will be obligated to pay Montgomery
the remainder of its fee upon the closing of the transactions contemplated by
the Reorganization Agreement. Montgomery also received $250,000 from Calgene
in February 1995 for investment banking services rendered in connection with a
potential transaction with Monsanto. Calgene has also agreed to reimburse
Montgomery for its reasonable out-of-pocket expenses. Pursuant to a separate
letter agreement, Calgene has agreed to indemnify Montgomery, its affiliates,
and their respective partners, directors, officers, agents, consultants,
employees and controlling persons against certain liabilities, including
liabilities under the federal securities laws.
 
  In the ordinary course of its business, Montgomery actively trades equity
securities of Calgene and Monsanto for its own account and for the accounts of
customers and, accordingly, may at any time hold a long or short position in
such securities. Montgomery has also performed certain investment banking
services for Calgene, including acting as co-manager of an underwritten public
offering of Calgene Common Stock in January 1993 and lead manager of an
underwritten public offering of Calgene Common Stock in October 1994. Certain
partners of Montgomery also own shares of Calgene's and Monsanto's common
stock.
 
MONSANTO'S REASONS FOR THE REORGANIZATION
 
  Monsanto's principal reasons for entering into the Reorganization are set
forth below:
 
  Monsanto believes that Calgene has established a leadership position in the
genetic engineering of plant oils for the food and chemical industries and
that plant oils represent a significant commercial opportunity. Monsanto
anticipates that its indirect investment in Calgene, through ownership of
Newco Common Stock, will enable Monsanto to participate in that opportunity.
Monsanto recognizes, however, that any commercial opportunity will only be
realized over the long term and there can be no assurance that such
opportunities will ever be realized.
 
                                      38
<PAGE>
 
  Monsanto believes that combining the produce-related biotechnology and
business assets of Gargiulo L.P. and Calgene will result in an enterprise that
is better positioned to develop, produce and market a family of high-value
produce products on a nationwide basis. There can be no assurance, however,
that the combination will produce the result Monsanto anticipates.
 
  Finally, Monsanto believes that Calgene is a leader in the development of
novel plant genetic engineering technologies, and that an indirect investment
in Calgene will provide a vehicle for Monsanto to gain access to such
technologies. Monsanto recognizes, however, that any commercially valuable
exploitation of such technology will only be realized over the long term and
there can be no assurance that any commercially valuable exploitation will
ever be realized.
 
INTERESTS OF CERTAIN PERSONS IN THE REORGANIZATION
 
  As of September 30, 1995, directors and executive officers of Calgene and
their affiliates may be deemed to beneficially own approximately 1.9% of the
outstanding shares of Calgene Common Stock. Each director and executive
officer of Calgene has advised Calgene that he intends to vote or direct the
vote of all shares of Calgene Common Stock over which he has voting control
FOR approval of the Merger Proposal. See "Calgene, Inc.--Executive
Compensation" and "Related Party Transactions" for a description of the terms
of employment agreements between Calgene and TIA and certain of their
respective executive officers.
 
ACCOUNTING TREATMENT
 
  The Merger will be accounted for under the purchase method of accounting in
accordance with generally accepted accounting principles, whereby the purchase
price will be allocated based on the fair value of the assets acquired and
liabilities assumed. Such allocations will be made based upon valuations that
have not been finalized. It is anticipated that a significant portion of the
purchase price will be allocated to in-process research and technology which
will result in a one-time charge to Newco's statement of operations of
approximately $59.2 million in the fiscal quarter in which the Reorganization
closes. The amount of the estimated one-time charge is based on a preliminary
valuation and the actual amount could vary significantly upon completion of
the final valuation.
 
  In addition, Newco plans to consolidate CalFresh with Gargiulo L.P. and, if
the Collier Transaction is consummated, to integrate the tomato operations of
Collier Farms. In connection with such consolidation activities, Newco expects
to close certain duplicative facilities and to incur restructuring charges,
including the write-off of redundant intangibles, of approximately $8.5
million which will be recorded in the fiscal quarter in which the
Reorganization closes.
 
  A significant effect of the purchase accounting will be to record a
significant amount of goodwill and other intangible assets, which will result
in substantial amortization charges to the consolidated income of Newco over
the useful lives of such assets. The amount of such charges are estimated at
approximately $6.5 million per year for a period of 12 years; however, actual
charges could vary significantly in the event the underlying assets are
impaired or the related useful lives are less than currently estimated. See
"Unaudited Selected Pro Forma Combined Financial Data."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
  The following is a summary of the material federal income tax consequences
to stockholders of Calgene upon the exchange of their Calgene Common Stock for
shares of Newco Common Stock pursuant to the Merger. This discussion reflects
the opinion of counsel attached as Exhibit 8.1 to the Registration Statement
of which this Proxy Statement/Prospectus is a part (the "Exhibit Opinion").
The Exhibit Opinion includes an opinion that the exchange of Calgene Common
Stock in the Merger for Newco Common Stock will qualify under Section 351 of
the Code as a tax-free exchange. The Exhibit Opinion, which is based upon
certain assumptions and subject to certain limitations and qualifications as
noted therein, was delivered by Hale and Dorr. This summary does not address
specific tax consequences that may be relevant to persons in special
circumstances (including, for example, persons who are employed by Calgene,
certain financial institutions, broker-dealers, insurance companies and tax-
exempt institutions). In addition, this summary does not address the tax
consequences of the Merger under the laws of any state, local or foreign
jurisdictions.

  STOCKHOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE
FEDERAL INCOME TAX CONSIDERATIONS THAT MAY BE SPECIFIC TO THEM, AS WELL AS
WITH RESPECT TO ANY STATE, LOCAL OR FOREIGN TAX CONSIDERATIONS THAT RELATE TO
THE MERGER OR THE HOLDING OF SHARES OF NEWCO.
 
  The following discussion is based on Hale and Dorr's interpretation of the
Code, applicable United States Treasury Regulations, judicial authority and
administrative rulings and practice as in effect on the date hereof. The
Internal Revenue Service (the "IRS") is not precluded from adopting a contrary
position. In addition, there can be no assurance that future legislative,
judicial or administrative changes or interpretations will not adversely
affect the accuracy of the statements and conclusions set forth herein. Any
such changes or interpretations could be applied retroactively and could
affect the tax consequences of the Merger to Calgene or its stockholders. In
addition, if the factual assumptions and representations underlying the
Exhibit Opinion should prove to be incorrect, the exchange of Calgene Common
Stock in the Merger may not qualify under Section 351 of the Code.
 
  Subject to the limitations and qualifications referred to herein, and as a
result of the exchange of Calgene Common Stock for Newco Common Stock in the
Merger qualifying under Section 351 of the Code, Hale and Dorr is of the
opinion that:
 
    1. No gain or loss for federal income tax purposes will be recognized by
  Calgene, Newco or Sub upon consummation of the Merger.
 
    2. A holder of Calgene Common Stock will recognize no gain or loss for
  federal income tax purposes upon the exchange of such stockholder's Calgene
  Common Stock for Newco Common Stock pursuant to the Merger.
 
    3. The aggregate tax basis in the shares of Newco Common Stock received
  by a holder of Calgene Common Stock in the Merger will equal such
  stockholder's aggregate adjusted basis in the shares of Calgene Common
  Stock surrendered in the Merger.
 
    4. The holding period for the shares of Newco Common Stock received by a
  holder of Calgene Common Stock in the Merger will include the holding
  period for the shares of Calgene Common Stock surrendered by the
  stockholder in the Merger provided that the shares of Calgene Common Stock
  were held as capital assets prior to the Merger.
 
  Calgene has not requested a ruling from the IRS in connection with the
Merger. However, it is a condition of the obligation of Calgene to consummate
the Merger that it receive a confirming tax opinion from its legal counsel to
the effect that the exchange of Calgene Common Stock for Newco Common Stock in
the Merger will qualify under Section 351 of the Code. The Exhibit Opinion is
not intended to satisfy this closing condition. The closing opinion does not
bind the IRS and does not preclude the IRS from adopting a contrary position.
As with the Exhibit Opinion, the closing opinion will be subject to certain
assumptions and qualifications and will be based on the truth and accuracy of
certain representations of Calgene and Monsanto, including representations in
certain certificates of the respective management of Calgene and Monsanto
dated on or prior to the date of this Proxy Statement/Prospectus.
 
FEDERAL SECURITIES LAW CONSEQUENCES
 
  All shares of Newco Common Stock received by the stockholders of Calgene in
the Merger will be freely transferable, except that shares of Newco Common
Stock received by persons who are deemed to be "affiliates" (as such term is
defined under the Securities Act) of Calgene prior to the Merger may be resold
by them only in transactions permitted by the resale provisions of Rule 145
promulgated under the Securities Act (or Rule 144 promulgated under the
Securities Act in the case of such persons who become affiliates of Newco),
pursuant to an effective Registration Statement under the Securities Act or as
otherwise permitted under the Securities Act.

NASDAQ NATIONAL MARKET QUOTATION
 
  The shares of Newco Common Stock to be issued in the Merger have been
approved for quotation on the Nasdaq National Market under the symbol "CGNE."
 
NO APPRAISAL RIGHTS
 
  Holders of Calgene Common Stock do not have rights of appraisal under the
Delaware Law in connection with the Merger. See "No Appraisal Rights."
 
REGULATORY APPROVALS
 
  No state or federal regulatory approvals are required relating to the
Reorganization, the Reorganization Agreement or the transactions contemplated
thereby other than (i) compliance with the HSR Act as described below, (ii)
the effectiveness of the Registration Statement of which this Proxy
Statement/Prospectus is a part, and (iii) compliance with applicable state
securities laws.
 
  The Reorganization is subject to the requirements of the HSR Act, and the
rules and regulations thereunder, which provide that certain transactions may
not be consummated until certain required information and materials have been
furnished to the Antitrust Division and the FTC and certain waiting periods
have expired or been terminated. Monsanto filed its notification pursuant to
the HSR Act in October 1995. (Calgene was not obligated to submit an HSR
notification). In November 1995, the Antitrust Division extended the HSR
waiting period on the proposed transactions by issuance of a request for
additional information to Monsanto pursuant to the HSR Act. The Antitrust
Division has also requested information from Calgene pursuant to the Antitrust
Civil Process Act. Both Monsanto and Calgene have provided significant
documentary and other information to the Antitrust Division in response to
these requests and continue to do so. Both companies expect to be in
substantial compliance with the requests they received in the near future. The
parties are continuing to work with the Antitrust Division to resolve any
remaining issues and believe that they will ultimately be able to resolve the
Antitrust Division's questions, if any, in a manner which will permit the
Reorganization to proceed.
 
  The Antitrust Division and the FTC frequently scrutinize the legality under
the antitrust laws of transactions such as the Reorganization. The termination
of the HSR Act waiting periods does not preclude the Antitrust Division or the
FTC from challenging the Reorganization (or any part thereof) on antitrust
grounds. Accordingly, at any time before or after the Effective Time, either
the Antitrust Division or the FTC could take such action under the antitrust
laws as it deems necessary or desirable in the public interest, or certain
other persons, including the attorney general of one or more states or private
parties, could take action under the antitrust laws, including seeking to
enjoin the Reorganization (or any part thereof).

              THE REORGANIZATION AGREEMENT AND RELATED AGREEMENTS
 
  The following is a brief summary of certain provisions of the Reorganization
Agreement, the Joinder Agreement, the Calgene Subordinated Promissory Note,
the Stockholders Agreement, the Newco Credit Facility Agreement, the Gargiulo
Credit Facility Agreement, the License Agreements and the Gargiulo
Reorganization Agreement. Such summary is qualified in its entirety by
reference to the Reorganization Agreement and the Stockholders Agreement which
are attached hereto as Annex A and Annex B and incorporated herein by
reference, and to the other agreements which have been filed as exhibits to
the Registration Statement of which this Proxy Statement/Prospectus is a part.
 
THE REORGANIZATION AGREEMENT
 
 The Merger
 
  The Reorganization Agreement provides that, following the approval of the
Merger Proposal by the requisite number of stockholders of Calgene, and the
satisfaction or waiver of the other conditions to the Merger, Sub will be
merged with and into Calgene, which will be the surviving corporation and a
wholly-owned subsidiary of Newco.
 
  If all such conditions to the Merger are satisfied or waived, the Merger
will become effective upon the filing by Newco, Calgene and Sub of a duly
executed Certificate of Merger with the Secretary of State of the State of
Delaware or at such time thereafter as is provided in such Certificate of
Merger.
 
 Conversion of Securities
 
  Upon consummation of the Merger each issued and outstanding share of Calgene
Common Stock (other than shares owned by Calgene as treasury stock, if any,
which will be cancelled) will be converted into the right to receive one share
of Newco Common Stock (the "Exchange Ratio"). Based on the number of Shares of
Calgene Common Stock outstanding on the Record Date, stockholders of Calgene
will receive an aggregate of approximately 30,264,257 shares of Newco Common
Stock in the Merger.
 
  If any person would be entitled to receive a fractional share of Newco
Common Stock in the Merger, then, in lieu of such fractional share, cash will
be paid in an amount equal to such fractional part of a share of Newco Common
Stock multiplied by the market value of Newco Common Stock. The market value
of one share of Newco Common Stock at the Effective Time shall be the last
sale price of such Newco Common Stock on the Nasdaq National Market (as
reported by The Wall Street Journal or other authoritative source) on the last
business day preceding such time or date if such stock is then being traded,
including, without limitation, trading on a "when issued" basis, and otherwise
shall be such price on the first business day that such stock is so traded. No
such holder shall be entitled to dividends, voting rights or any other
stockholder right in respect of any fractional share.
 
 Ownership of Newco after the Reorganization
 
  The ownership of Newco Common Stock immediately following consummation of
the Reorganization will be as follows:

</TABLE>
 
 Treatment of Calgene Stock Option Plans
 
  Upon the Effective Time, Newco will assume all options outstanding under
Calgene's stock option plans and such options may be exercised solely for
shares of Newco Common Stock. Each such option shall be
 
                                      42
<PAGE>
 
converted into the right to purchase a number of shares of Newco Common stock
equal to the number of shares of Calgene Common Stock subject to such option
multiplied by the Exchange Ratio, and the per share exercise price of each
such option shall be adjusted by dividing such exercise price by the Exchange
Ratio.
 
 Related Matters After the Merger
 
  At the Effective Time, Sub will be merged with and into Calgene, and Calgene
will be the surviving corporation (the "Continuing Corporation") and a wholly-
owned subsidiary of Newco. Each share of Sub Common Stock issued and
outstanding immediately prior to the Effective Time will be converted into and
exchanged for one validly issued, fully paid and nonassessable share of common
stock of the Continuing Corporation.
 
  At the Effective Time, the Certificate of Incorporation and By-laws of
Calgene, as in effect immediately prior to the Effective Time, will continue
to be the Certificate of Incorporation and By-laws of the Continuing
Corporation.
 
  After the Effective Time, all shares of Calgene Common Stock will cease to
be quoted on The Nasdaq National Market, and the Continuing Corporation will
undertake to terminate registration of the Calgene Common Stock under the
Exchange Act.
 
 Representation on the Newco Board
 
  The Stockholders Agreement provides that, at the Effective Time, the Newco
Board shall consist of the Chief Executive Officer and Chief Operating Officer
of Newco, three directors to be designated by Newco and four directors to be
designated by Monsanto (one of which shall be an independent director). The
Stockholders Agreement also provides certain rights to Monsanto to designate
additional directors under certain circumstances. See "The Reorganization
Agreement and Related Agreements--The Stockholders Agreement" and "Calgene II,
Inc.--Directors and Executive Officers."

outstanding at the time the Reorganization Agreement was executed and the
designation and issuance of $1,000 of Calgene Preferred Stock, which shall be
non-voting and non-convertible and shall otherwise have such terms as shall
have been approved by Monsanto) or grant or issue any option, warrant, call,
right, commitment or agreement of any character relating to its authorized or
issued capital stock, or issue, grant or sell any preferred stock or any
securities or obligations convertible into or exchangeable for shares of its
capital stock other than the issuance and sale of shares of Calgene Common

 No Solicitation
 
  Calgene
 
  The Reorganization Agreement provides that Calgene shall not, directly or
indirectly, through any officer, director, employee, agent, representative,
consultant, financial institution or otherwise, solicit, initiate or encourage
the submission of any proposal or offer from any person relating to (i) any
acquisition or purchase of all or substantially all of the assets or business
of Calgene or any of its subsidiaries or (ii) any business combination with
Calgene or any of its subsidiaries (all such transactions in clause (i) and
(ii) being referred to as "Calgene Acquisition Transactions") or, except to
the extent required by fiduciary obligations under applicable law as advised
by counsel (in which case, Calgene shall promptly advise Monsanto of its
intention to invoke this exception), participate in any negotiations
regarding, or furnish to any other person or entity any non-public information
with respect to, or otherwise cooperate in any way with, or assist or
participate in, facilitate or encourage, any effort or attempt by any other
person to do or seek any of the foregoing. The Reorganization Agreement
required Calgene to immediately cease and cause to be terminated all existing
discussions or negotiations with any parties conducted prior to the execution
of the Reorganization Agreement with respect to any of the foregoing. Calgene
is required to promptly notify Monsanto if any such proposal or offer, or any
inquiry or contact with any person or entity with respect thereto, is made and
shall, in any such notice to Monsanto, indicate in reasonable detail the
identity of the person or entity making such proposal, offer, inquiry or
contact. Calgene further agreed not to release any third party from, or waive
any provision of, any confidentiality or standstill agreement to which Calgene
is a party.
 
  Monsanto and TIA
 
  The Reorganization Agreement provides that Monsanto shall not, directly or
indirectly, through any officer, director, employee, agent, representative,
consultant, financial institution or otherwise, solicit, initiate or encourage
the submission of any proposal or offer from any person relating to (i) any
acquisition or purchase of all or substantially all of the assets or business
of TIA or (ii) any business combination with TIA (all such transactions in
clause (i) and (ii) being referred to as "Monsanto Acquisition Transactions")
or, except to the extent required by fiduciary obligations under applicable
law as advised by counsel (in which case Monsanto shall promptly advise
Calgene of its intention to invoke this exception), participate in any
negotiations regarding, or furnish to any other person any non-public
information with respect to, or otherwise cooperate in any way
 
                                      45
<PAGE>
 
with, or assist or participate in, facilitate or encourage, any effort or
attempt by any other person to do or seek any of the foregoing. The
Reorganization Agreement required Monsanto to immediately cease and cause to
be terminated all existing discussion or negotiations with any parties
conducted prior to the execution of the Reorganization Agreement with respect
to any of the foregoing. Monsanto is required to promptly notify Calgene if
any such proposal or offer, or any inquiry or contact with any person or
entity with respect thereto, is made and shall, in any such notice to Calgene,
indicate in reasonable detail the identity of the person or entity making such
proposal, offer, inquiry or contact. Monsanto further agreed not to release
any third party from, or waive any provision of, any confidentiality or
standstill agreement to which Monsanto is a party.
 
 Non-Competition
 
  Monsanto has agreed that, upon the Effective Time and for as long as
Monsanto's ownership in Newco exceeds 25% and is less than 100% of the
outstanding shares of Newco Common Stock, Monsanto shall not engage in any
"Directly Competitive Activity" with Calgene. "Directly Competitive Activity"
is defined in the Reorganization Agreement to mean and refer only to the
commercialization by Monsanto (or one of its affiliates, other than Newco and
any of its affiliates) of any genetically engineered fresh or processed
tomatoes, berries, mangoes, cucurbits or peppers or the commercialization of
any genetically engineered canola, oil seed rape or sunflower where the
canola, oil seed rape or sunflower has been genetically engineered to produce
a specialty oil product. "Directly Competitive Activity" excludes the
licensing of patent rights or know-how for the commercialization of such
genetically engineered crops or the commercialization of canola, oil seed rape
or sunflower where the canola, oil seed rape or sunflower has been genetically
engineered for a purpose other than to produce a specialty oil product.
 
 Indemnification
 
  Monsanto
 
  The Reorganization Agreement provides that, except as otherwise specifically
provided therein or in the other Transaction Agreements, Monsanto shall
indemnify and hold harmless, in the manner specified in the Reorganization
Agreement, Newco and its directors, officers, employees and agents, from and
against any and all Liabilities, Actions and Damages (as defined in the
Reorganization Agreement) suffered or incurred by said indemnified parties
with respect to: (i) any inaccuracy of representations and warranties made in
the Reorganization Agreement or pursuant to Article 6 thereof by Monsanto,
(ii) breaches on or prior to the Closing Date of certain covenants made in any
of the Transaction Agreements by Monsanto which breaches, if curable, are not
cured within sixty (60) days after written notice thereof from Calgene, (iii)
the failure of Monsanto to comply with any applicable bulk sales law and (iv)
any taxes actually payable by Newco, TIA or General Partner attributable to
the recapture or acceleration of any Internal Revenue Code Section 481
adjustment which arose upon formation of Gargiulo L.P., net of any reductions
to taxes actually payable by Newco, TIA or General Partner as a result of
corollary adjustments attributable to such Section 481 adjustments. No claim
for indemnification may be made against Monsanto unless, and only to the
extent that, the claim exceeds $2.5 million. The maximum amount of Monsanto's
indemnification obligation is limited to $20 million, except for matters
involving fraud.
 
  Newco and Calgene
 
  The Reorganization Agreement provides that, except as otherwise specifically
provided therein or in the other Transaction Agreements, Newco and Calgene
shall, jointly and severally, indemnify and hold harmless, in the manner
specified in the Reorganization Agreement, Monsanto and Monsanto's Agents (as
defined in the Reorganization Agreement), against Liabilities, Actions and
Damages (as defined in the Reorganization Agreement) arising from: (i) any
inaccuracy of representations or warranties made in the Reorganization
Agreement or pursuant to Article 6 thereof by Calgene, or (ii) breaches on or
prior to the Closing Date of covenants made in any of the Transaction
Agreements by Calgene or Newco which breaches, if curable, are not cured
within sixty (60) days after written notice thereof from Monsanto. No claim
for indemnification may be made against Newco and Calgene unless, and only to
the extent that, the claim exceeds $2.5 million.

  The obligations of Calgene to effect the Merger and the other transactions
contemplated by the Reorganization Agreement are subject to the following
conditions, among others: (i) the accuracy in all material respects on the
Closing Date of the representations and warranties of Monsanto set forth in
the Reorganization Agreement and the performance in all material respects on
or prior to the Closing Date of the obligations of Monsanto required to be
performed under the Reorganization Agreement; (ii) the receipt by Calgene of
certain legal opinions from counsel for Monsanto; (iii) the instruments of

restrains, prohibits or prevents or in the reasonable opinion of Calgene's
counsel presents a significant risk of restraining, prohibiting or preventing,
or changing the terms of, or obtaining material damages in connection with,
the Reorganization; (v) there shall have occurred no Material Adverse Effect
upon TIA, the Business of Gargiulo L.P. (as defined in the Reorganization

 Termination; Termination Fees
 
  The Reorganization Agreement may be terminated and the Reorganization
(including, without limitation, the Merger) abandoned at any time prior to the
Effective Time, whether before or after approval by the stockholders of
Calgene: (i) by mutual consent of the Calgene Board and the Monsanto Board;
(ii) by either the Monsanto Board or the Calgene Board if the Merger is not
consummated on or before March 31, 1996, unless such failure to consummate
shall be due to the failure of the party seeking to terminate the
Reorganization Agreement to perform in all material respects each of its
obligations under the Reorganization Agreement; (iii) by the Calgene Board or
the Monsanto Board in the event that the Calgene Board shall withdraw or
change its recommendation to its stockholders to adopt and approve the
Reorganization Agreement and the Merger or authorize the Reorganization, as
the case may be, or if the Calgene stockholders fail to adopt and approve the
Reorganization Agreement or the Merger Proposal; (iv) by the Monsanto Board if
Calgene shall breach its obligations set forth in Section 9.9(a) of the
Reorganization Agreement not to solicit, initiate or encourage a proposal or
offer relating to a Calgene Acquisition Transaction; (v) by the Monsanto Board
if events occur that render impossible of satisfaction one or more of the
conditions set forth in Section 8.2 of the Reorganization Agreement and such
conditions are not waived (or deemed waived) by Monsanto; and (vi) by the
Calgene Board if events occur that render impossible of satisfaction one or
more of the conditions set forth in Section 8.1 of the Reorganization
Agreement and such conditions are not waived (or deemed waived) by Calgene.
 
  In the event of either (i) a withdrawal, change in a manner adverse to
Monsanto or failure by the Calgene Board to make its recommendation to Calgene
stockholders to approve the Merger Proposal, or (ii) a breach by Calgene of
its obligations under Section 9.9(a) of the Reorganization Agreement, and
thereafter a Calgene Acquisition Transaction is consummated within 12 months
after the termination or abandonment of the Reorganization Agreement, Calgene
may be required to pay Monsanto a termination fee in cash equal to $7.5
million.
 
JOINDER AGREEMENT
 
  Prior to Closing, Newco, Sub (neither of which had been incorporated at the
time the Reorganization Agreement was executed), Calgene and Monsanto will
sign a Joinder Agreement (the "Joinder Agreement") as required by the
Reorganization Agreement. The purpose and effect of the Joinder Agreement is
for each of Newco and Sub: (i) to bind themselves to the terms of the
Reorganization Agreement; (ii) to ratify and adopt certain indemnification
obligations set forth in the Reorganization Agreement; (iii) to provide for
the survival of certain representations and warranties in the Reorganization
Agreement; (iv) to make standard representations regarding their due
organization, existence and capitalization, and (v) to convenant that all
statements in the Proxy Statement/Prospectus about themselves will be in
compliance with the federal securities laws and will not omit any material
facts. Additionally, under the Joinder Agreement, each of Newco, Sub and
Calgene will guarantee the performance of each other's obligations under the
Reorganization Agreement and the Joinder Agreement and agree that they each
shall be jointly and severally responsible for the performance of the
obligations of the other and for the accuracy of the representations and
warranties of each in the Reorganization Agreement and the Joinder Agreement.
 
CALGENE SUBORDINATED PROMISSORY NOTE
 
  Pursuant to the terms of a subordinated promissory note of Calgene in favor
of Monsanto, Calgene borrowed $10 million from Monsanto on June 29, 1995. The
original promissory note was amended and restated on September 27, 1995 to
permit Calgene to borrow an additional $8 million. As of December 31, 1995,
all $18 million of principal was outstanding under the Amended Note.
 
  The Amended Note is due on June 30, 1997; provided, however, that if the
Reorganization is not consummated because (i) Calgene's stockholders fail to
approve the Merger Proposal or (ii) any of Monsanto's other conditions to
Closing set forth in the Reorganization Agreement, to the extent such
conditions are within the control of Calgene, are not satisfied at or prior to
Closing, then the maturity date of the Amended Note shall be June 30, 1996.
 
                                      48
<PAGE>
 
  The principal balance of the Amended Note from time to time outstanding
bears interest at the per annum rate equal to 2.00% above Citibank's prime
rate as published monthly. Interest is payable at maturity or on the date of
prepayment as to any principal amount prepaid. If all or a portion of
outstanding principal amount of the Amended Note is not paid when due, the
outstanding principal balance thereof shall bear interest for the period from
the applicable due date until such amount is paid in full, at the rate per
annum which is equal to 5% above the Note Rate. Calgene may prepay all or any
portion of the Amended Note at any time.
 
  Upon consummation of the Reorganization, the outstanding principal amount
due under the Amended Note shall be credited against the $30 million cash
contribution to be made to Newco by Monsanto in connection with the
Reorganization. Interest on the Amended Note will stop accruing at the
Effective Time and all interest accrued prior to such time shall be waived by
Monsanto.
 
  The Amended Note is subordinated in payment to certain senior indebtedness
of Calgene, as more fully described in the Amended Note. No payment on account
of principal or interest on the Amended Note shall be made, if at the time of
such payment or immediately after giving the effect thereto, (i) there shall
exist a default in any payment with respect to any such senior indebtedness or
(ii) there shall have occurred an event of default (other than a default in
the payment of amounts due thereon) with respect to any such senior
indebtedness which has not been cured, waived or ceased to exist and which
would permit the holder thereof to accelerate the maturity thereof.
 
  If the Transaction Agreements are terminated for any reason (a "Conversion
Event"), then, from and after 60 days following such Conversion Event, the
principal and accrued interest due under the Amended Note will be convertible,
at Monsanto's option, at any time and in any amount, into shares of Calgene
Common Stock at 85% of the average of the closing market prices for such
shares during the 10 trading days immediately preceding the Conversion Date
(as defined in the Amended Note). Based upon the last reported sales price of
Calgene Common Stock on the Nasdaq National Market on December 15, 1995
($4.875 per share), the conversion of the Amended Note in such an event would
result in the issuance of approximately 4,343,891 shares of Calgene Common
Stock to Monsanto, or approximately 14% of the total number of shares of
Calgene Common Stock currently outstanding. The Amended Note is convertible
into a maximum number of shares of Calgene Common Stock (the "Conversion
Shares") equal to (a) 7,200,000 shares (subject to adjustment in the event of
any merger, consolidation, reorganization, recapitalization, stock dividend,
stock split, exchange of shares or otherwise) multiplied by (b) a fraction,
the numerator of which is equal to the lesser of (i) the principal and accrued
interest outstanding under the Amended Note on the Conversion Date and
(ii) $18 million, and the denominator of which is equal to $18 million. Upon
any such conversion, the amount of principal and interest so converted shall
be applied to reduce first any accrued interest and thereafter to reduce the
principal due on the Amended Note. Any portion not so converted shall be paid
in cash. If the proceeds received by Monsanto from the resale of the
Conversion Shares, net of all reasonable expenses (including brokerage or
underwriting fees, discounts and commissions and fees and expenses of legal
counsel) incurred by Monsanto in connection therewith (the "Selling
Expenses"), exceed the principal and accrued interest converted into such
Conversion Shares and any other transaction costs, fees and expenses incurred
by Monsanto and not included in the Selling Expenses (such excess being
hereafter referred to as the "Excess Cash Proceeds"), then (i) any remaining
principal amount and accrued interest on the Amended Note shall be forgiven by
Monsanto to the extent of the Excess Cash Proceeds and (ii) Monsanto shall
repay any remaining Excess Cash Proceeds (after reduction for the amount of
principal and accrued interest forgiven) to Calgene promptly after receipt
thereof.
 
  Calgene agreed under the Amended Note to file a Registration Statement on
Form S-3 with the Commission covering resales of up to 3,600,000 Conversion
Shares which may be issued to Monsanto under the Amended Note. Subject to
certain limitations, Calgene is obligated to cooperate with Monsanto to effect
the sale of the Conversion Shares, including using its best efforts to
register or qualify the Conversion Shares under applicable securities and blue
sky laws and to maintain the effectiveness of such Form S-3 until the earlier
of (i) such time
 
                                      49
<PAGE>
 
as all Conversion Shares issuable upon Conversion have been sold pursuant
thereto, or (ii) such time as all Conversion Shares may be sold without
registration pursuant to Rule 144(k) under the Securities Act. Not later than
60 days after a Conversion Event, Calgene shall cause the Conversion Shares
issuable upon such Conversion Event to be listed on each securities exchange
and quoted on each quotation service on which similar securities of Calgene
are then listed or quoted. All expenses incurred in connection with the
registration of the Conversion Shares shall be borne by Calgene except Calgene
shall not be required to pay (i) brokerage or underwriting fees, discounts or
commissions or (ii) the fees and expenses of Monsanto's counsel.
 
  The Amended Note includes certain covenants of Calgene, including covenants
concerning: (i) the use of proceeds; (ii) delivery of certain financial
information; (iii) insurance; (iv) obtaining any required governmental
authorization or approvals and the filing of required notices; (v) maintenance
of business; (vi) limitations on mergers, acquisitions or sales of assets;
(vii) incurrence of additional debt; (viii) extending credit;
(ix) investments; (x) incurrence of liens; and (xi) payment of dividends.
 
THE STOCKHOLDERS AGREEMENT
 
  The Reorganization Agreement provides that Monsanto and Newco shall enter
into a Stockholders Agreement at the Effective Time providing for the
following:
 
 Registration Rights
 
  The Stockholders Agreement provides that Monsanto and certain assignees may,
subject to certain conditions and limitations, require Newco, whether or not
Newco proposes to register its Common Stock for sale, to register all or part
of the shares of Newco Common Stock acquired by Monsanto in connection with
the Reorganization or upon the later conversion of outstanding principal or
interest under the Newco Credit Facility Agreement or the Gargiulo Credit
Facility Agreement (collectively, the "Registrable Shares") under the
Securities Act and to register or qualify such Registrable Shares under any
applicable state securities or blue sky laws so as to permit Monsanto to sell
such Registrable Shares in the public markets. Newco is not required to effect
such a registration prior to September 30, 1998, unless an Event of Default
has occurred and is continuing under the Newco Credit Facility Agreement or
the Gargiulo Credit Facility Agreement, in which event Newco is required to
effect a registration of the Registrable Shares received in such conversion at
the request of Monsanto or its assignee. Newco is required to pay all of the
expenses (other than certain expenses of Monsanto, such as
 
                                      50
<PAGE>
 
underwriting discounts and selling commissions) with respect to up to four (4)
such registrations. In the event Newco proposes to register any of its
securities under the Securities Act at any time after September 30, 1998, for
its own account (other than a registration relating to employee benefit plans
or a Commission Rule 145 transaction), Monsanto is entitled to notice of such
registration and to include Registrable Shares, subject to certain conditions
and limitations. The registration rights granted pursuant to the Stockholders
Agreement shall terminate at such time as (a) all Registrable Shares can be
sold within a given three month period without registration under the
Securities Act pursuant to Rule 144 of the Securities Act and (b) all accrued
interest and principal under the Newco Credit Facility Agreement and the
Gargiulo Credit Facility Agreement have been repaid in full or converted into
Newco Common Stock (and such Newco Common Stock can be sold as provided in
clause (a) above).
 
 Anti-Dilution Rights
 
  If at any time after the Effective Time Newco agrees to sell shares of Newco
Common Stock or other securities having the right to vote generally in any
election of directors of Newco (collectively, "Newco Securities") in a private
or public offering (other than pursuant to Newco's stock option plans),
Monsanto is entitled to notice of such proposed sale and has the right, but
not the obligation, to acquire all or any portion of the Newco Securities to
be offered for sale sufficient for Monsanto to maintain, after the
consummation of the proposed offering, the same percentage of ownership of
Newco Securities as Monsanto possessed immediately prior to such offering.
With respect to shares of Newco Securities issued pursuant to Newco's stock
option plans, Monsanto shall have the right to maintain its percentage
ownership of issued and outstanding Newco Securities by making open market
purchases in accordance with the Stockholders Agreement.
 
 Limitations on Monsanto's Ownership of Newco Securities
 
  Except for purchases of Newco Securities made in accordance with the
Stockholders Agreement, during the term of the Stockholders Agreement,
Monsanto shall not, directly or indirectly, acquire any Newco Securities
except as follows: (a) prior to the first anniversary of the Effective Time,
Monsanto shall not increase its percentage of ownership of issued and
outstanding Newco Securities (the "Percentage Interest") above 49.9% except
through one or more of the following: (i) conversion of principal and/or
interest under the Newco Credit Facility Agreement or the Gargiulo Credit
Facility Agreement into shares of Newco Common Stock; (ii) issuance of Newco
Securities in an asset sale by Monsanto to Newco; and (iii) a tender offer by
Monsanto for no less than 100% of all publicly-traded Newco Securities at a
price approved by the disinterested directors of Newco and based upon a
fairness opinion delivered to the Newco Board by an investment banking firm;
(b) on and after the first anniversary of the Effective Time until the earlier
of September 30, 1998, or the third anniversary of the Effective Time,
Monsanto shall not increase or further increase its ownership of issued and
outstanding Newco Securities above 49.9% except through one or more of the
following: (i) conversion of principal and/or interest under the Newco Credit
Facility Agreement or the Gargiulo Credit Facility Agreement into shares of
Newco Common Stock; (ii) issuance of Newco Securities in an asset sale by
Monsanto to Newco; and (iii) a tender offer by Monsanto to increase its
ownership to 70% or more of the issued and outstanding Newco Securities at a
price approved by the disinterested directors of Newco and based upon a
fairness opinion delivered to the Newco Board by an investment banking firm;
provided, however, that if Monsanto makes a tender offer to increase its
ownership to more than 80% of the issued and outstanding Newco Securities,
such tender offer must be for at least 100% of all publicly traded Newco
Securities; and (c) after the earlier of September 30, 1998, or the third
anniversary of the Effective Time, Monsanto may increase its ownership of
Newco Securities through open market purchases or otherwise.
 
 Limitations on Monsanto's Resale of Newco Securities
 
  The Stockholders Agreement provides that Monsanto shall not, directly or
indirectly, sell any Newco Securities (other than to an Affiliate) except as
follows: (a) on and after the first anniversary of the Effective Time until
the earlier of September 30, 1998, or the third anniversary of the Effective
Time, Monsanto may sell Newco Securities (i) as part of a joint venture,
merger or sale of all or substantially all of its current Crop
 
                                      51
<PAGE>
 
Protection business unit, as such business may be subsequently renamed or
reorganized, or (ii) pursuant to a tender offer by a third party to the
stockholders of Newco; (b) after the earlier of September 30, 1998, or the
third anniversary of the Effective Time, in addition to the rights set forth
in (a) above, Monsanto may sell Newco Securities (i) in a registered public
offering pursuant to the registration rights granted to Monsanto under the
Stockholders Agreement; (ii) through sales pursuant to Rule 144 under the
Securities Act; (iii) through sales of not more than 10% of the total issued
and outstanding Newco Securities to a Non-Financial Purchaser (as defined in
the Stockholders Agreement); or (iv) through sales to a Financial Purchaser
(as defined in the Stockholders Agreement); (c) after the earlier of September
30, 1999, or the fourth anniversary of the Effective Time, in addition to the
rights set forth in (a) and (b) above, Monsanto may sell Newco Securities
through a private sale of 35% or more of the total issued and outstanding
Newco Securities to a Non-Financial Purchaser under circumstances where such
third party assumes the applicable and proportionate rights and obligations of
Monsanto under the Stockholders Agreement and the other Transaction
Agreements; and (d) notwithstanding the foregoing, at any time after the
Effective Time, Monsanto may sell Newco Securities issued to Monsanto upon
conversion by Monsanto of principal or interest under the Newco Credit
Facility Agreement or the Gargiulo Credit Facility Agreement after the
occurrence of an Event of Default (as defined therein).
 
 Composition of the Newco Board and Calgene Board
 
  The Stockholders Agreement provides that the composition of the Newco Board
and the Calgene Board and the manner of selecting members thereof shall be as
follows:
 
    (a) at and after the Effective Time, each of the Newco Board and the
  Calgene Board shall be comprised of nine directors. The number of Newco
  Directors and Calgene Directors may be increased only in accordance with
  the terms of the Stockholders Agreement;
 
    (b) at the Effective Time and until the earlier of any time that (i)
  Monsanto's percentage ownership of the outstanding Newco Securities
  ("Percentage Interest") is at least 55% or (ii) Newco elects to convert
  borrowings made from Monsanto into equity securities of Newco and
  Monsanto's Percentage Interest is at least 50% after such conversion (a
  "Trigger Event"), each of the Newco Board and the Calgene Board shall
  consist of two directors who are either the Chief Executive Officer or
  Chief Operating Officer of Newco (or the next most highly ranking executive
  officers of Newco) ("Company Management Directors"), three Independent
  Directors (as defined in the Stockholders Agreement) designated by Newco
  ("Company Directors"), and four directors designated by Monsanto (each a
  "Monsanto Director"), at least one of which shall be an Independent
  Director (as defined in the Stockholders Agreement);
 
    (c) at and after the occurrence of a Trigger Event, each of the Newco
  Board and the Calgene Board shall be comprised of eleven Directors and
  Monsanto shall have the right to designate two additional directors to each
  Board; and
 
    (d) at any time that Monsanto's Percentage Interest is at least 70%, (i)
  Monsanto shall have the right to designate eight Newco Directors and eight
  Calgene Directors, to consist of the two Company Management Directors and
  six other directors designated by Monsanto (including at least one
  Independent Director) and (ii) Newco shall have the right to designate
  three (3) Independent Directors to each board. At such time as Monsanto's
  Percentage Interest is at least 99%, Monsanto shall have the right to
  designate all of the Newco Directors and Calgene Directors.
 
  The initial Company Management Directors will be Roger H. Salquist, the
Chief Executive Officer of Calgene, and another executive officer to be
designated; the initial Company Directors will be Howard D. Palefsky, Carl V.
Stinnett and Allen J. Vangelos, who are currently directors of Calgene; and
the four Monsanto Directors will be Hendrik A. Verfaillie and Robert T.
Fraley, who currently are Executive Vice President of Monsanto and President
of Ceregen, a strategic business unit of Monsanto, respectively, Jeffrey D.
Gargiulo, who is currently Chairman and Chief Executive Officer of Gargiulo
L.P., and John E. Robson, a senior advisor of Robertson, Stephens & Company.
 
  Notwithstanding anything in the foregoing to the contrary, (i) at any time
Monsanto's Percentage Interest is less than 40% but at least twenty percent
(20%), Monsanto shall have the right to designate three Newco
 
                                      52
<PAGE>
 
Directors and three Calgene Directors, (ii) at any time Monsanto's Percentage
Interest is less than 20% but at least 10%, Monsanto shall have the right to
designate two Newco Directors and two Calgene Directors, and (iii) at any time
Monsanto's Percentage Interest is less than 10% but at least 5%, Monsanto
shall have the right to designate one Newco Director and one Calgene Director.
If, at any time, Monsanto's Percentage Interest is less than 5%, Monsanto
shall not have the right to designate any Newco Director or Calgene Director.
At any such time, all other Newco Directors and Calgene Directors, other than
Newco Management Directors, shall be designated by Newco.
 
  The Independent Directors to be designated by Newco from time to time shall
be designated by action of a majority of Company Directors then in office. In
the event that no Company Directors are in office at such time, such
Independent Directors shall be designated by a majority of the Independent
Directors then in office; provided, however, that the holders of a majority of
the outstanding voting stock held by Unaffiliated Equity Holders (as defined
in the Stockholders Agreement) shall be entitled to nominate and elect
Independent Directors in lieu of any individuals so designated to be such
Independent Directors by a majority of the Independent Directors.
 
 Solicitation and Voting of Shares
 
  Newco is obligated to use its best efforts to solicit from the stockholders
of Newco proxies in favor of all directors nominated in accordance with the
Stockholders Agreement. Newco and Monsanto shall also cooperate with each
other with respect to the election, removal and replacement of all directors

Independent Directors then serving on the Newco Board, responsible for
retention and/or replacement of all of the executive officers of Newco; (iii)
a Compensation Committee; and (iv) such other committees as the Newco Board
deems necessary or desirable. Except as otherwise provided in the Stockholders
Agreement or as agreed by a majority of the Monsanto Management Directors (as
defined in the Stockholders Agreement), the number of Monsanto Directors on
each committee of the Newco Board shall be the same proportion (but not less
than one) of the total membership of such committee as the number of Monsanto
Directors, as the case may be, is of the entire Newco Board.
 
  No action by any committee of the Newco Board shall be valid unless taken by
a unanimous written consent as provided in Newco's By-Laws or taken at a
meeting for which adequate notice has been duly given or waived by the members
of such committee. Such notice shall include a description of the general
nature of the business to be transacted at the meeting, and no other business
may be transacted at such meeting unless all members of the committee are
present and consent to the consideration of other business. Any committee
member unable to participate in person at any meeting shall be given the
opportunity to participate by telephone. The Newco Board or the remaining
committee members shall designate an Independent Director or Company
Management Director to replace any absent or disqualified Independent Director
member or Company Management Director member, respectively, of any committee
and a majority of the Monsanto Management Directors shall designate a Monsanto
Director to replace any absent or disqualified Monsanto Director member of any

for approval, and any material changes thereto; (x) any transaction between

(other than royalties contingent on future sales) exceeding $5 million in the
aggregate (determined on a consolidated basis) per transaction or per series
of related transactions; (xv) new fixed capital investments, capital leases or
noncancellable operating leases by Newco and its Affiliates having annual
payments in the aggregate (determined on a consolidated basis) exceeding the
aggregate amount set forth in the Operating Plan; (xvi) matters relating to
Gargiulo L.P. covered in Article 5 of the Stockholders Agreement, including,
without limitation, any changes in the composition of the TIA Board of

have an adverse public affairs effect upon Monsanto or the filing of any
insolvency or bankruptcy proceeding by or on behalf of Newco or any of its
Affiliates; or (xix) the removal or election of the directors, subject to the
terms of the Stockholders Agreement, of TIA.
 
  (b) After a Trigger Event and until the earlier of (i) the third anniversary
of the Effective Time or (ii) such time as Monsanto's Percentage Interest is
at least seventy percent (70%), a majority of the Newco Board, including at
least two Company Directors, shall be required to approve any of the
following: (i) except as
 
                                      54
<PAGE>
 
provided in the Stockholders Agreement, the matters set forth in clauses (ii),
(vi), (viii), (ix) and (xi) of paragraph (a) above; or (ii) any transaction
between Newco (and its Affiliates) and Monsanto or any Affiliate of Monsanto.
 
  (c) From and after the occurrence of both (i) a Trigger Event and (ii) the
third anniversary of the Effective Time, and until Monsanto's Percentage
Interest is at least 99%, neither Monsanto nor any of its Affiliates shall
enter into any transaction with Newco or any of its Affiliates without the
approval of at least two Company Directors.
 
 Board of Directors and Management of TIA
 
  Upon the Effective Time, the TIA Board shall consist of Jeffrey D. Gargiulo,
John R. Gargiulo, Hendrik A. Verfaillie, Robert T. Fraley, Roger H. Salquist,
Roderick N. Stacey and an additional director who shall be (and whose
successor shall be) designated by Newco who shall need to be reasonably
acceptable to Monsanto and Jeffrey D. Gargiulo (as long as he serves as a
director). In addition, the TIA Board shall include two (2) advisory, non-
voting directors designated by Monsanto from members of the senior management
of TIA. Upon request by Monsanto, Newco shall remove and replace Messrs.
Verfaillie and Fraley, and their respective successors, and replace them with
persons designated by Monsanto. The other directors, other than Messrs.
Salquist and Stacey, may not be changed without the approval of Monsanto
pursuant to the exercise of its rights described above under "Approval
Required for Certain Actions."
 
  The Chief Executive Officer and Chairman of the Board of TIA shall be
Jeffrey D. Gargiulo as long as he is employed by TIA. See "Related Party
Transactions."
 
  The Board of Directors of TIA shall have authority to operate the business
of Gargiulo L.P. within the confines of the annual operating plan and
strategic plan approved by the Board of Directors of Newco and other
delegations of authority from the Newco Board which shall be similar in scope
to the delegations of the Newco Board to the Chief Executive Officer of Newco.
 
NEWCO CREDIT FACILITY AGREEMENT
 
  The Reorganization Agreement provides that, upon the Effective Time,
Monsanto and Newco shall enter into the Newco Credit Facility Agreement
pursuant to which Monsanto shall, during the Commitment Period (as hereinafter
defined), and subject to the terms and conditions contained therein, make, at
the request of Newco, three consecutive one-year loans of up to $15 million
each (each a "Newco Loan" and together the "Newco Loans"), collectively
totalling not more than $45,000,000. At no time shall the outstanding
principal of all Newco Loans exceed $15 million. Prior to the occurrence of an
Event of Default (as defined in the Newco Credit Facility Agreement), Newco
may borrow, repay and reborrow under each Newco Loan, each such borrowing or
reborrowing being an "Advance." The "Commitment Period" begins the date of the
Effective Time and ends on the earlier of September 30, 1998, the third
anniversary of the Effective Time or such earlier time that Monsanto
terminates its obligations to make further Advances under the Newco Credit
Facility Agreement. The Newco Loans made pursuant to the Newco Credit Facility
Agreement are to be secured by the joint and several guaranty of the
subsidiaries of Newco.
 
  Prior to the occurrence of an Event of Default, the Newco Loans shall bear
interest at the per annum rate equal to 2.00% above Citibank's published prime
rate (the "Newco Base Rate"), and following an Event of Default at the per
annum rate equal to 3.00% above the Newco Base Rate. During the continuance of
an Event of Default, Newco shall have no right to obtain any new Advances
under this Agreement. The Newco Loans may be prepaid in whole or in part at
any time after giving at least three days' prior written notice to Monsanto.
 
  In lieu of repayment of outstanding principal and accrued interest on each
Newco Loan, Newco, subject to Monsanto's right to require Newco to sell shares
and pay cash, as provided below, may elect to convert all or any portion of
the principal and accrued interest due under the applicable Newco Loan (the
"Conversion Amount") into shares of Newco Common Stock at the average of the
closing market price for such shares during the thirty trading days
immediately preceding the applicable maturity date for such Newco Loan.
 
                                      55
<PAGE>
 
  Monsanto may, in its sole discretion and within five business days after its
receipt of notice from Newco that Newco intends to exercise Newco's rights to
convert the Conversion Amount, give written notice to Newco stating that (i)
all or any part of the Conversion Amount shall be payable in cash (the
"Alternative Conversion Amount"), (ii) Newco shall, at its expense, sell
publicly such number of shares of its common stock as Monsanto would have
received if the Alternative Conversion Amount had been converted as described
above and (iii) the net proceeds of such sale shall be paid by Newco to
Monsanto in full payment and satisfaction of such Alternative Conversion
Amount.
 
  Upon any such conversion, the Conversion Amount shall first be applied to
reduce the accrued interest due on the applicable Newco Loan as of the
applicable maturity date, and any remaining portion of the Conversion Amount
shall be applied to reduce the principal due on such Newco Loan. In any event,
on each annual Maturity Date (as defined in the Newco Credit Facility
Agreement), all outstanding principal and accrued interest not converted by
Newco into shares of Newco Common Stock shall be repaid in full to Monsanto.
 
  Upon the occurrence and during the continuation of an Event of Default, for
a period of thirty (30) days from the occurrence of the Event of Default,
Newco, subject to Monsanto's right to require Newco to sell shares and pay
cash, as described above, may similarly elect to convert all or any portion of
the principal and accrued interest under any outstanding Newco Loan into
shares of Newco Common Stock. If Newco does not elect to exercise its
conversions rights upon such an Event of Default, Monsanto may, in addition to
its other remedies, elect to convert all or a portion of the remaining
principal and accrued interest under such Newco Loan into shares of Newco
Common Stock at the average of the closing market prices for such shares
during he thirty days preceding such Event of Default. In no event, however,
shall Monsanto elect to convert principal and accrued interest into more than
3,000,000 shares of Newco Common Stock (as such number is adjusted for stock
dividends, stock splits and similar event affecting holders of Newco's common
stock).
 
  The obligation of Monsanto to provide Advances is subject to the fulfillment
of certain conditions, including, among others: (i) the continued accuracy of
all representations and warranties made by Newco and its subsidiaries; (ii)
the compliance with all covenants contained in the Newco Credit Facility
Agreement; (iii) no event shall have occurred which would constitute an Event
of Default or Potential Event of Default (as defined in the Newco Credit
Facility Agreement); or (iv) there shall not have occurred any circumstance
which could reasonably be expected to have a material adverse effect on (A)
the business, assets, operations or financial condition of Newco and its
subsidiaries, taken as a whole, or (B) the ability of the Company and its
subsidiaries to perform their obligations under the Newco Credit Facility
Agreement.
 
  The covenants contained in the Newco Credit Facility Agreement require Newco
to maintain a minimum consolidated net worth of not less than $10 million and
a minimum consolidated working capital of not less than $5 million. The Newco
Credit Facility Agreement also requires that Newco and its subsidiaries meet
certain specified financial ratios, including a ratio of total long-term
liabilities to net worth and a current ratio. In addition, the Newco Credit
Facility Agreement imposes a number of limitations on Newco with respect to
future acquisitions, liens, mergers and the sale of assets, loans and
investments, guaranties, capital expenditures, the payment of dividends and
the incurrence of indebtedness. The existence of these covenants could limit
Newco's ability to finance the growth of its existing operations if cash flows
were to decrease substantially or if expenses were to increase substantially.
These covenants would also limit Newco's ability to engage in additional
acquisitions that would significantly increase the ratio of long-term
indebtedness to net worth following such acquisitions. The failure of Newco to
satisfy these covenants would cause an Event of Default which could have a
material adverse effect on its business and results of operations.
 
  All of the Newco Loans shall be subordinated and subject in right of payment
to the prior payment in full of a certain senior indebtedness of Newco as more
fully described in the Newco Credit Facility Agreement. No payment on account
of principal or interest on the Newco Loans shall be made if at the time of
such payment or immediately after giving the effect thereto, (i) there shall
exist a default in any payment with respect to any such senior indebtedness or
(ii) there shall have occurred an event of default (other than a default in
the payment of amounts due thereon) with respect to any such senior
indebtedness.

GARGIULO CREDIT FACILITY AGREEMENT
 
  The Reorganization Agreement provides that, upon the Effective Time,
Monsanto and Newco shall enter into the Gargiulo Credit Facility Agreement
pursuant to which Monsanto shall, during the Commitment Period (as hereinafter
defined), and subject to the terms and conditions contained therein, make
available to Newco a revolving credit facility of up to $40 million (the
"Gargiulo Loan"). Gargiulo L.P. expects to borrow up to $40 million from
Monsanto pursuant to an amendment to an existing credit facility to acquire
Collier Farms, to support the branded tomato strategy and to allow Gargiulo
L.P. to make an approximately $2 million payment to Monsanto pursuant to the
Development Agreement, which amounts will be converted into a loan under the
Gargiulo Credit Facility Agreement at the Effective Time.
 
  The balance of the Gargiulo Loan shall be used solely to support the branded
tomato strategy of TIA as determined by the TIA Board of Directors (other than
amounts used to finance the acquisition of Collier Farms). Prior to the
occurrence of an Event of Default (as defined in the Gargiulo Credit Facility
Agreement), Gargiulo may borrow, repay and reborrow, each such borrowing or
reborrowing being an "Advance." In order to obtain an Advance from Monsanto
under the Gargiulo Credit Facility Agreement, Newco must provide documentation
reasonably acceptable to Monsanto verifying that TIA has reached certain
milestones and achieved certain goals as set forth therein. The maximum amount
of each Advance is subject to certain limitations based upon such milestones
and goals. The "Commitment Period" begins the date of the Effective Time and
ends on the earlier of the fourth anniversary of the Effective Time or such
earlier time that Monsanto terminates its obligations to make further
Advances. The Gargiulo Loan is to be secured by the joint and several guaranty
of the subsidiaries of Newco.
 
  Prior to the occurrence of an Event of Default, the Gargiulo Loan shall bear
interest at the per annum rate equal to 2.00% above Citibank's published prime
rate (the "Gargiulo Base Rate"), and following an Event of Default at the per
annum rate equal to 3.00% above the Gargiulo Base Rate. During the continuance
of an Event of Default, Newco shall have no right to obtain any new Advances.
The Gargiulo Loan may be prepaid in whole or in part at any time after giving
at least three days' prior written notice to Monsanto.
 
  The Gargiulo Loan is payable, unless extended as described below, in one
payment on the fourth anniversary of the Effective Time (the "Maturity Date")
in an amount equal to the lesser of (i) the Repayment Portion of the
Cumulative Free Cash Flow (as defined in the Gargiulo Credit Facility
Agreement) of TIA from the Effective Time to the Maturity Date and (ii) the
amount of the outstanding principal and accrued interest on the Gargiulo Loan.
"Repayment Portion" means the sum of 20% of the first $10 million of
Cumulative Free Cash Flow, 50% of the next $10 million and 80% of the
remaining balance. In the event that the Repayment Portion is not sufficient
to pay all of the then outstanding principal and accrued interest at the
Maturity Date, the maturity date with respect to the unpaid amount of
outstanding principal and interest shall be extended to the sixth anniversary
of the Effective Time (the "Extended Maturity Date"). In the event the
Repayment Portion of the Cumulative Free Cash Flow (less amounts previously
paid) is not sufficient to pay the then outstanding principal and accrued
interest at the Extended Maturity Date, Newco shall pay Monsanto such lesser
amount and the maturity date with respect to the unpaid amount of outstanding
principal and interest shall again be extended to the eighth anniversary of
the Effective Time (the "Final Maturity Date"). If the Repayment Portion of
the Cumulative Cash Flow (less amounts previously paid) is not sufficient to
pay the then outstanding principal and accrued interest at the Final Maturity
Date, then Newco shall pay to Monsanto such lesser amount and Monsanto, at its
sole option, may do any one or combination of the following (i) convert all or
any portion of the then outstanding principal and accrued interest into shares
of Newco Common Stock at the average of the closing market price for such
shares during the thirty trading days immediately preceding the date of such
conversion, (ii) further extend the Final Maturity Date upon the same terms as
are contained in the Gargiulo Credit Facility Agreement, or (iii) as to any
unpaid amount which is not converted under clause (i) or for which payment is
not extended pursuant to clause (ii), cause Newco to sell publicly that number
of shares of Newco Common Stock as Monsanto would have received if such amount
has been converted under clause (i) above with the net proceeds of such sale
being delivered to Monsanto in full payment and satisfaction of such amount.

  Upon the occurrence and during the continuation of an Event of Default,
Monsanto may, in addition to its other remedies, similarly elect to convert
all or any portion of the principal and accrued interest under the Gargiulo
Loan (the "Gargiulo Conversion Amount") into shares of Newco Common Stock at
the average of the closing market prices for such shares during the thirty
days preceding such Event of Default. In no event, however, shall Monsanto
elect to convert principal and accrued interest into more than 8,000,000
shares of Newco Common Stock (as such number is adjusted for stock dividends,
stock splits and similar event affecting holders of Newco's common stock).
Upon any such conversion, the Gargiulo Conversion Amount shall first be
applied to reduce the accrued interest due on the Gargiulo Loan, and any
remaining portion of the Gargiulo Conversion Amount shall be applied to reduce
the principal due on such Gargiulo Loan.
 
  The obligation of Monsanto to provide Advances is subject to the fulfillment
of certain conditions, including, among others: (i) the continued accuracy of
all representations and warranties made by Newco and its subsidiaries; (ii)
the compliance with all covenants contained in the Gargiulo Credit Facility
Agreement; (iii) no event shall have occurred which would constitute an Event
of Default or Potential Event of Default (as defined in the Gargiulo Credit
Facility Agreement); or (iv) there shall not have occurred any circumstance
which could reasonably be expected to have a material adverse effect on (A)
the business, assets, operations or financial condition of Newco and its
subsidiaries, taken as a whole or (B) the ability of the Company and its
subsidiaries to perform their obligations under the Gargiulo Credit Facility
Agreement.
 
  The covenants contained in the Gargiulo Credit Facility Agreement require
Newco to maintain a minimum consolidated net worth of not less than $10
million and a minimum consolidated working capital of not less than $5
million. The Gargiulo Credit Facility Agreement also requires that Newco and
its subsidiaries meet certain specified financial ratios, including a ratio of
total long-term liabilities to net worth and a current ratio. In addition, the
Gargiulo Credit Facility Agreement imposes a number of limitations on Newco
and each of its subsidiaries with respect to future acquisitions, liens,
mergers and the sale of assets, loans and investments, guaranties, capital
expenditures, the payment of dividends and the incurrence of indebtedness. The
existence of these covenants could limit Newco's ability to finance the growth
of its existing operations if cash flows were to decrease substantially or if
expenses were to increase substantially. These covenants would also limit
Newco's ability to engage in additional acquisitions that would significantly
increase the ratio of long-term indebtedness to net worth following such
acquisitions. The failure of Newco to satisfy these covenants would cause an
Event of Default which could have a material adverse effect on its business
and results of operations.
 
  The Gargiulo Loan is to be subordinated and subject in right of payment to
the prior payment in full of certain senior indebtedness of Newco as more
fully described in the Gargiulo Credit Facility Agreement. No payment on
account of principal or interest on the Gargiulo Loan shall be made if at the
time of such payment or immediately after giving the effect thereto, (i) there
shall exist a default in any payment with respect to any such senior
indebtedness or (ii) there shall have occurred an event of default (other than
a default in the payment of amounts due thereon) with respect to any such
senior indebtedness.
 
LICENSE AGREEMENTS
 
  As part of the Reorganization, Monsanto will contribute certain technology
licenses to Newco pursuant to various license agreements and letter
agreements. The technologies underlying the License Agreements are summarized
below.
 
  ACC Synthase and ACC Deaminase. ACC is a precursor of ethylene, a plant
growth regulator that induces ripening in certain fruits. By reducing the
amount of ACC available for conversion into ethylene, the ripening process can
be delayed. Control of the ripening process may enable Newco to improve the
efficiency of its tomato production operations. Newco will be granted non-
exclusive, perpetual, royalty-free rights to the ACC synthase and ACC
deaminase genes for use in certain produce crops and shall be able to practice
under Monsanto's ACC Synthase license from the USDA.
 
 
                                      58
<PAGE>
 
  Fruit-specific Promoters. Promoters control the expression of genes in each
plant cell. In order for certain genes to function in a beneficial manner,
expression of these genes must be restricted to certain parts of the plant.
Fruit-specific promoters provide a means of limiting gene expression to the
fruit. For example, these promoters may be useful in regulating carbohydrate
metabolism (e.g., sugar content) in ripening fruits such as tomatoes and
strawberries. Newco will be granted non-exclusive, perpetual, royalty-free
rights to certain fruit-specific promoters for use in certain produce crops.
 
  Virus Resistance Genes. Virus infection is known to significantly reduce the
yields of certain crops, including tomatoes. Monsanto has developed methods of
interfering with viral replication in engineered plants, which slows the rate
and degree of infection, and reduces the yield loss resulting from the
infection. Newco will be granted non-exclusive, perpetual, royalty-free or
royalty-bearing rights to certain aspects of Monsanto's patent estate related
to the engineering of virus resistance into certain produce crops.
 
  FAD 3 Gene. The FAD 3 gene controls the relative amount of polyunsaturated
fatty acids found in plant oils, including canola oil. Newco believes that
reducing the expression of the FAD 3 gene in engineered canola plants may
result in an oil with reduced linoleic and linolenic acid content and
increased oleic acid content. Such an oil would be a superior cooking oil, as
well as a superior raw material for the production of margarine and
shortening. Newco will be granted exclusive, perpetual, royalty-bearing rights
to the FAD 3 gene for use in certain oilseed crops.
 
  Insect Resistance Gene. Monsanto has modified genes from a soil
microorganism called Bacillus thurengiensis ("B.t.") that encode proteins that
are toxic to certain insects. Use of insecticides to control insects is a
major cost in the production of tomatoes. Newco will be granted non-exclusive,
perpetual, royalty-free rights to Monsanto's B.t. patent estate for use in
certain produce crops.
 
  ADP Glucose Pyrophosphorylase ("ADPGPP") Gene. The ADPGPP gene is a
bacterial gene involved in starch biosynthesis. By expression of this gene in
plants, the starch and/or sugar content of plants can be increased. This many
improve the flavor or sweetness of produce crops such as tomatoes or
strawberries. Newco will be granted non-exclusive, perpetual, royalty-free
rights to Monsanto's patent estate related to ADPGPP for use in certain
produce crops. Monsanto and Calgene are parties to an interference at the
United States Patent and Trademark Office relating to the ADPGPP gene.
 
  Oil Modification Technology. Monsanto has certain patent rights and know-how
related to the production of plants with altered oil compositions. By
modifying oil composition it may be possible to provide temperate sources of
certain tropical oils and the production of novel oil compositions. The
Monsanto oil modification genes include sucrose phosphorylase, cytochrome b5
and PEP carboxylase. Newco will be granted non-exclusive, perpetual, royalty-
free rights under Monsanto's patents and know-how for use in certain oilseed
crops.
 
 Insect Protected Cotton Direct Grower Licensing Agreement
 
  Calgene has entered into an agreement with Monsanto under which Newco will
participate in the direct licensing of Monsanto's B.t. technology to cotton
growers. Under the terms of this agreement, Monsanto has granted to Calgene a
non-exclusive, royalty-free U.S. license to use Monsanto's B.t. technology in
Calgene's cottonseed products. Subject to the issuance of a Monsanto patent
that covers the B.t. gene that is currently being utilized in Newco's
cottonseed product development program, Newco would be obligated under
applicable patent law to end use of its current B.t. gene and is permitted
under such agreement to incorporate Monsanto's B.t. gene into its product
development program over a four-year period.
 
  Monsanto intends to enter into license agreements directly with cotton
growers. Under the terms of these agreements, cotton growers would obtain a
one-time right to purchase a specified number of units of cottonseed
containing Monsanto's B.t. gene in return for the payment of a license fee.
Monsanto has agreed to pay to Newco 29% of the net license fees received from
licensed growers who subsequently purchase Newco's cottonseed products
containing Monsanto's B.t. gene.
 
                                      59
<PAGE>
 
  Newco's obligation to participate in the direct licensing program would
survive the termination of the Reorganization Agreement. Furthermore, the
material terms of Newco's agreement shall be modified to reflect any more
favorable terms that may be granted to any other cottonseed company that may
participate in the direct licensing program.
 
GARGIULO REORGANIZATION AGREEMENT
 
  Monsanto, TIA, NTGargiulo, Inc. ("NTGCo"), Gargiulo L.P., the General
Partner and certain stockholders of NTGCo entered into an Option and Retained
Interests Agreement, dated as of July 29, 1994 (the "Option and Retained
Interests Agreement"), pursuant to which TIA acquired an option (the "Option")
to acquire from NTGCo all of the outstanding shares of capital stock of the
General Partner that TIA did not then own and such partnership interests in
Gargiulo L.P. as would result, after the exercise of such option, in TIA and
the General Partner owning an aggregate of 82% of the partnership interests in
Gargiulo L.P. Under the Option and Retained Interests Agreement, the exercise
price for such option was $32.1 million. Pursuant to the Gargiulo
Reorganization Agreement, TIA agreed to exercise the Option on the earlier of
January 31, 1996 or immediately prior to the Effective Time (the "Closing
Date"). Upon the exercise of such Option, (i) TIA would own all of the issued
and outstanding shares of capital stock of the General Partner, (ii) TIA would
own interests in Gargiulo L.P., directly or indirectly through the General
Partner, equal to 82% of such partnership interests and NTGCo would own
partnership interests in Gargiulo L.P. equal to 18% of such partnership
interests.
 
  On January 31, 1996, TIA exercised the Option for $32.1 million and acquired
the remaining 18% partnership interest in Gargiulo L.P. for an additional $18
million, less the total amount of certain loans by Gargiulo L.P. to its
limited partners. As of February 1, 1996, TIA owned, directly or indirectly
through the General Partner, all of the equity interests in Gargiulo L.P.
 
  Immediately after the Effective Time, the General Partner will be dissolved
and liquidated, and its assets transferred to and liabilities assumed by TIA.
TIA will succeed to all the assets and liabilities of the General Partner,
including its partnership interests in Gargiulo L.P. Gargiulo L.P. will then
be dissolved by operation of law and TIA will succeed to all of its assets and
liabilities.
 
  The Gargiulo Reorganization Agreement provides that, immediately after the
acquisition by TIA from NTGCo of all of the partnership interests in Gargiulo
L.P. then held by NTGCo: (i) the Option and Retained Interests Agreement shall
be terminated; (ii) the Development Agreement between Gargiulo L.P. and
Monsanto shall be amended to, among other things, convert the licenses granted
pursuant to the Development Agreement to fully paid-up licenses; and (iii) the
Amended and Restated Credit Agreement dated as of July 29, 1994 between MAP
Investment Company, an operating unit of Monsanto, and Gargiulo L.P. shall
either (x) if the Effective Time shall have occurred, be terminated and any
loans outstanding thereunder shall be repaid by Gargiulo L.P. in full;
provided, that if borrowings are outstanding thereunder to finance the
proposed acquisition of Collier Farms, such borrowings shall be refinanced
pursuant to the Gargiulo Credit Facility Agreement; or (y) if the Effective
Time shall not have occurred, be extended to the earlier of the eighth
anniversary of the Closing Date and the date the Effective Time shall occur
and be amended to provide that the amount that may be borrowed by Gargiulo
L.P. thereunder shall be increased to $40 million; provided, however, that $30
million of the proceeds may be used only to support and implement the branded
tomato strategy and the remaining $10 million may be used in connection with
Gargiulo L.P.'s proposed acquisition of Collier Farms or, if such acquisition
does not occur, then such $10 million shall be used to support and implement
the branded tomato strategy.

          UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS
 
  The following unaudited Pro Forma Combined Condensed Balance Sheet as of
September 30, 1995 and the unaudited Pro Forma Combined Condensed Statements
of Operations for the three months ended September 30, 1995 and the year ended
June 30, 1995, give effect to the business combinations involving Calgene II,
Inc. ("Newco"), Tomato Investment Associates, Inc. and Produce Related
Technology of Monsanto Company; Gargiulo L.P. and subsidiaries; Collier Farms;
and Calgene, Inc. accounted for using the purchase method of accounting. The
Pro Forma Combined Condensed Balance Sheet is presented as if the business
combinations had occurred on September 30, 1995, and the Pro Forma Combined
Condensed Statements of Operations are presented as if the business
combination had occurred as of July 1, 1994. The pro forma information is
presented for illustrative purposes only and may not be indicative of the
results that would have been obtained had the transactions actually occurred
on the dates assumed nor is it necessarily indicative of the future combined
results of operations. Calgene has retained independent valuation
professionals to assist in the final determination of the value to be assigned
to the individual assets acquired including the intangibles and in-process
research and technology. The valuation and the determination of the final
purchase price will depend on the number of shares to be issued as well as the
market price of Newco Common Stock. However, the results of the preliminary
valuation have been included in the pro forma adjustments to the condensed
balance sheet.
 
  The pro forma combined condensed financial statements should be read in
conjunction with the historical financial statements and the related notes
thereto of Calgene II, Inc., Tomato Investment Associates, Inc. and Produce
Related Technology of Monsanto Company; Gargiulo L.P. and subsidiaries;
Collier Farms; and Calgene, Inc.

      NOTES TO UNAUDITED PRO FORMA COMBINEDCONDENSED FINANCIAL STATEMENTS
 
  1. REORGANIZATION AND MERGER. As of September 30, 1995, Tomato Investment
Associates, Inc., a wholly-owned subsidiary of Monsanto Company, owns certain
produce related technology and a 49.9% interest in Gargiulo L.P. and
Subsidiaries. In connection with the Reorganization described in the following
paragraph, TIA will acquire the remaining equity interest in Gargiulo L.P.
(collectively "TIA/Gargiulo").
 
  In the Reorganization and related Merger, Calgene and TIA will become
wholly-owned subsidiaries of Calgene II, Inc. ("Newco") Simultaneously, Newco
will be renamed Calgene, Inc., at which time Monsanto will own common stock
representing a 49.9% equity interest in Newco (assumed for purposes hereof to
have an approximate fair market value of $200 million). Prior to the
completion of the Reorganization, Gargiulo L.P. intends to acquire Collier
Farms. The acquisitions of TIA, Gargiulo L.P. and Collier Farms will be
accounted for using the purchase method of accounting.
 
  2. TIA ACQUISITION OF GARGIULO L.P. As of September 30, 1995, TIA owns a
49.9% equity interest in Gargiulo L.P. and will acquire the remaining equity
interest of Gargiulo L.P. for approximately $50.1 million. The purchase price
of $50.1 million is based on an option acquired in 1992 from Garguilo L.P. by
TIA at which time TIA purchased an initial 23% equity interest. The difference
in Newco's cost to acquire Garguilo L.P. and the price paid by TIA
approximates $34 million. A separate purchase price allocation has not been
performed for the TIA/Gargiulo L.P. pro forma adjustments because a complete
purchase price allocation, including TIA's acquisition of the remaining
outside equity interest of Gargiulo, will be presented based on the Calgene
acquisition of TIA/Gargiulo L.P. For purposes of the TIA/Gargiulo L.P. pro
forma financial information, the excess purchase price has temporarily been
shown entirely as costs in excess of fair values assigned to net assets
acquired. Costs in excess of fair values assigned to net assets acquired of
$68.073 million is determined as follows:

  3. PROPOSED PURCHASE OF COLLIER FARMS. Prior to the completion of the
Reorganization, Gargiulo L.P. intends to acquire substantially all the assets
excluding related party receivables, subject to certain liabilities of Collier
Farms for $10 million in cash and a $10 million promissory note, plus an earn-
out payment based upon certain earnings of the combined operations of the
Partnership in southwest Florida and those being purchased from the Seller.
The Partnership will also acquire the seller's investment in the 1995-1996
crop to be calculated at closing and assume liabilities related thereto. The
acquisition of Collier Farms will be accounted for as a purchase.
 
  The estimated purchase price consists of the following:

  4. ACQUISITION OF TIA/GARGIULO L.P. As described in Note 1, Monsanto will
acquire a 49.9% equity interest in Newco with an assumed approximate fair
value of $200 million in exchange for $30 million in cash (of which $13
million has been previously advanced at September 30, 1995 pursuant to a
subordinated promissory note), and 100% ownership in TIA/Gargiulo L.P. and

  As of September 30, 1995, Calgene has received $13 million in advances
toward the $30 million proceeds for Newco Common Stock in the form of a
subordinated promissory note.
 
  5. INTANGIBLE ASSETS. Intangible assets include completed technology,
assembled workforce and costs in excess of fair values assigned to net assets
acquired. The estimated useful lives are expected to range from 3 to 15 years.
For presentation purposes, purchased intangibles have been amortized using an
average 12-year period. Calgene management does not believe that technological
feasibility of the acquired in-process technology has been established.
Further, Calgene management believes the acquired technology has no
alternative future uses. Therefore, the $59.2 million allocated to in-process
research and technology is required to be immediately expensed under generally
accepted accounting principles. Such amount is a non-recurring charge related
to the Reorganization and as such is not reflected in the Pro Forma Statement
of Operations pursuant to Regulation S-X.
 
  6. PRO FORMA ADJUSTMENTS. Adjustments to the Pro Forma Condensed Combined
Balance Sheet were made:
 
    (a) To record TIA's acquisition of the remaining 50.1% equity interest in
  Gargiulo L.P. and eliminate the investment in affiliate and Gargiulo L.P.
  equity accounts.

    (b) To eliminate certain intercompany assets and liabilities that will
  not be acquired/assumed.
 
    (c) To eliminate the costs in excess of fair values assigned to net
  assets recorded by TIA (see (a) above) and record the acquisition and
  allocate the purchase price (based on preliminary appraised values) of
  TIA/Gargiulo L.P. and the receipt of $30 million in cash (less the $13
  million advance) in exchange for Newco Common Stock assumed to have an
  approximate fair market value of $200 million. The accumulated deficit has
  been adjusted for the effect of expensing the in-process research and
  technology. Also, to write-off or reserve for $8.5 million of intangibles,
  leases and related assets that became redundant upon the acquisition of
  TIA/Gargiulo. Such amount is a non-recurring charge related to the
  Reorganization and as such is not reflected in the Pro Forma Statement of
  Operations pursuant to Regulation S-X.
 
    (d) To record the $10 million, five year promissory note issued and a $10
  million advance under an existing credit facility with an affiliate of
  which will be converted into a loan under the Gargiulo Credit Facility
  Agreement upon the Effective Time from Monsanto for the acquisition of
  Collier Farms. The promissory note is payable in 20 equal quarterly
  installments following the closing of the Reorganization. The advance is
  payable in one payment at the end of four years but may be extended to
  eight years based on defined events.
 
    (e) To eliminate assets and liabilities of Collier Farms that will not be
  acquired/assumed as part of the acquisition.
 
    (f) To allocate the purchase price of the acquisition of Collier Farms.
 
    ADJUSTMENTS TO THE PRO FORMA CONDENSED COMBINED STATEMENT OF OPERATIONS
  WERE MADE TO:
 
    (g) To record the amortization of the additional costs in excess of fair
  values assigned to net assets acquired in TIA's acquisition of Gargiulo
  L.P.
 
    (h) To eliminate TIA's share of net loss in affiliate.
 
    (i) To eliminate the amortization related to (g) above and the
  amortization of the costs in excess of fair values assigned to net assets
  recorded by TIA during the fiscal year ended June 30, 1995.
 
    (j) To record the amortization of the purchased intangibles.
 
 
    (k) To record interest expense on the $10 million promissory note issued

INTRODUCTION
 
  In December 1992, Monsanto, through its wholly-owned subsidiary, TIA,
contributed cash totalling approximately $24.6 million and certain technology
and know-how related to tomatoes to Gargiulo L.P. in exchange for an
approximately 22% partnership interest in Gargiulo L.P.
 
  In July 1994, TIA increased its percentage ownership of Gargiulo L.P. to
49.9% by paying approximately $27.9 million to the other partners of Gargiulo
L.P. At the same time, TIA and the other partners of Gargiulo L.P. entered
into an Option and Retained Interests Agreement pursuant to which (i) TIA
obtained, for a payment of $5.2 million, the Option to increase its ownership
interest in Gargiulo L.P. to 82% at a specified price at any time prior to
January 31, 1996 and (ii) if such Option were exercised, TIA obtained certain
call rights, and granted certain put rights, exercisable after December 31,
1999, for TIA to acquire the remaining partnership interests of Gargiulo L.P.
at a formula price.
 
  In connection with the Reorganization, Monsanto, TIA and the partners of
Gargiulo L.P. entered into the Gargiulo Reorganization Agreement pursuant to
which (i) TIA agreed to exercise its Option to increase its ownership interest
in Gargiulo L.P. to 82% by paying the option price of $32.1 million to NTGCo,
which is the other limited partner of Gargiulo L.P., and (ii) TIA agreed to
purchase the remaining 18% partnership interest in Gargiulo L.P. for a
purchase price of $18 million. See "The Reorganization Agreement and Related
Agreements--Gargiulo Reorganization Agreement." On January 31, 1996, TIA
exercised the Option and acquired the remaining 18% partnership interest in
Gargiulo L.P. NTGCo is owned 50% by Joseph Procacci and 16.66% each by Dewey
Gargiulo and his sons, Jeffrey D. Gargiulo and John R. Gargiulo.
 
GARGIULO L.P.
 
 Overview
 
  Gargiulo L.P. engages in the growing, packaging, marketing and distribution
of tomatoes and strawberries and, to a lesser extent, other fresh fruits and
vegetables. Gargiulo L.P. also engages in breeding research with respect to
tomatoes and, to a lesser extent, strawberries. Gargiulo L.P.'s tomato
producing operations are conducted principally in southwest and northern
Florida, north central California, Virginia, Puerto Rico and Mexico. Gargiulo
L.P.'s berry production operations are conducted principally in northern
California. Tree fruits are grown in Chile, and potatoes, which Gargiulo L.P.
began producing, packing and distributing for the first time in January 1995,
are grown in southwest Florida. Gargiulo L.P.'s corporate headquarters are
located in Naples, Florida.
 
  Gargiulo L.P.'s predecessor companies (the "Predecessors") began brokering
tomatoes in southwest Florida in the early 1950's. Operations were
subsequently expanded to include the production of tomatoes in southwest
Florida and over the years the Predecessors and later Gargiulo L.P. commenced
tomato growing operations in northern Florida, northern California, and, in
order to be able to supply tomatoes in the winter in the event of a freeze in
Florida, in Puerto Rico. More recently, Gargiulo L.P. entered into a joint
venture with a company located in Mexico for the production and distribution
of tomatoes and peppers. In order to be able to supply tomatoes throughout the
United States and Canada on a year round basis, which will be integral to
Newco's branded tomato strategy, in 1994, Gargiulo L.P. began the production
of tomatoes in Virginia.
 
  In order to diversify the product line, in the early 1980's the Predecessors
commenced an operation to grow, cool, market and distribute strawberries in
northern California. Gargiulo L.P. acquired interests in companies in Chile in
1987 for the production, sale and importation into the United States of
various winter fruits, including nectarines and grapes. Through a relationship
with a Chilean grower, during the winter months in the United States, Gargiulo
L.P. also imports and markets raspberries and asparagus.
 
  Gargiulo L.P. believes it has managed to achieve recognition among the
wholesalers, retailers, brokers and food service entities which it serves, as
a reputable and reliable supplier of tomatoes and berries. Gargiulo L.P.
 
                                      74
<PAGE>
 
intends to continue to concentrate its efforts in this business and to
capitalize, whenever possible, on the opportunities to profit in the commodity
fruit and vegetable business. With its vertically integrated structure,
management, marketing and research capabilities and its established
distribution channels, Gargiulo L.P. believes it is well positioned to take
advantage of opportunities in the commodity fruit and vegetable markets.
 
 Acquisition of Collier Farms
 
  Pursuant to the Collier Purchase Agreement, Gargiulo L.P. has agreed to
acquire substantially all of the assets, subject to the assumption of certain
specified liabilities, of the produce business conducted by certain affiliates
of Collier Enterprises (the "Seller") under the trade name of "Collier Farms."
Collier Farms is an agricultural producer of tomatoes and other vegetables in
southwest Florida, and engages in the packaging, marketing and distribution of
those products into the commodity markets. See "--Collier Farms." If the
Collier Transaction is consummated, the purchase price to be paid by Gargiulo
L.P. for Collier Farms would be approximately $20 million, payable $10 million
in cash and $10 million in the form of a purchase money note payable to the
Seller, maturing on June 30, 2000, subject to reduction in the event Gargiulo
L.P. assumes certain obligations of the Seller to Prudential Life Insurance
Company in the approximate amount of $5 million (as adjusted, the "Seller
Note"), plus the assumption of all expenses incurred by Collier Farms since
July 1, 1995, which expenses relate to the production of Collier Farms' 1995-
1996 crop. In addition, Gargiulo L.P. would make an earn-out payment to the
Seller after the fiscal year ended June 30, 2000, based upon the future
earnings of the combined southwest Florida operations of Collier Farms and
Gargiulo L.P. (calculated as if Gargiulo L.P. had not implemented the branded
tomato strategy). The Seller Note and earn-out payment would be secured by the
Collier Farms assets being purchased and the Seller Note would be additionally
secured by certain farmland owned by Gargiulo L.P., all of which is located in
Collier County, Florida.
 
  The Collier Purchase Agreement also provides that Gargiulo L.P. will enter
into a long-term lease with affiliates of the Seller (the "Collier Lease") for
a minimum of 6,000 acres of farmland in southwest Florida, with the right to
lease up to an additional 5,000 acres of farmland. The initial term of the
Collier Lease would be five years and Gargiulo L.P. would be granted three
options of five years each to extend such lease. The rent to be paid by
Gargiulo L.P. under the Collier Lease will be a market rate less a small
discount, which discount increases as more land is leased. The Collier
Purchase Agreement provides for a closing of the Collier Transaction subject
to the terms and conditions contained therein by January 31, 1996, which may
be extended until February 28, 1996. See "--Collier Farms."
 
 Products
 
  Tomatoes. Gargiulo L.P.'s principal product is fresh tomatoes. For Fiscal
1995, Gargiulo L.P. packed and shipped approximately 270 million pounds of
fresh tomatoes, which it produced through its own farming operations, through
joint ventures or partnerships with other growers or pursuant to contractual
arrangements with other growers. For Gargiulo L.P.'s and its Predecessors'
fiscal years ended June 30, 1993, 1994 and 1995, product revenues from
Gargiulo L.P.'s tomato operations were approximately $44.1 million, $50.3
million and $60.1 million, representing 54.3%, 50.6% and 52.7%, respectively,
of Gargiulo L.P.'s total revenues for those fiscal years.
 
  Gargiulo L.P.'s tomato operations are vertically integrated with seed
research, production, packing, repacking, distribution, marketing, and sales
capabilities. With production available year round from its various locations,
Gargiulo L.P. believes it is well positioned for consistent year round supply
of tomatoes to customers throughout the United States and Canada.
 
  Gas Green Tomatoes. Approximately 90% of the tomatoes produced by Gargiulo
L.P. during Fiscal 1995 were harvested and processed as green tomatoes. Green
tomatoes are sorted by grade and size according to specifications promulgated
by the USDA and are typically packed into 25 pound boxes. The tomatoes are
then stored at 65(degrees)F in the presence of ethylene gas for one to four
days. This process allows the tomato to achieve a deep red color acceptable to
the retail consumer and results in a sufficient shelf-life so that the tomato
reaches the retail consumer in an acceptable condition. The vast majority of
tomatoes produced in the United States are harvested green and processed in
this manner.
 
                                      75
<PAGE>
 
  Vine Ripened Tomatoes. Gargiulo L.P., through its participation in a joint
venture with a Mexican partner, has the capability to produce tomatoes which
are ripened on the vine, packed and then shipped. The relatively arid climate
in which the Mexican tomatoes are produced, contrasted with the wetter climate
in which tomatoes are grown in the United States, allows for vine ripening
which many retail consumers believe results in a better tasting tomato than
tomatoes which are picked green and ripened off the vine.
 
  Branded Tomatoes. In 1993, Gargiulo L.P. commenced market research to
determine the interests of consumers in a "branded tomato." To be sold as
branded, a tomato must consistently and uniformly combine all of the
characteristics and attributes retail consumers generally look for in
tomatoes, such as pleasing flavor, tempting color, and good size, shape and
firmness. Gargiulo L.P. is embarking upon a branded tomato program to produce
and market a premium tomato under the Gargiulo name.
 
  The success of the branded tomato strategy will depend in large measure on
Gargiulo L.P.'s ability (i) to induce customers to identify Gargiulo L.P.'s
premium tomato with the Gargiulo name, (ii) to induce consumers to pay a
premium price for that superior tomato, and (iii) to be able to produce and
deliver that tomato to customers on a consistent, year round basis. Based on
market research performed by Gargiulo L.P. to date, Gargiulo L.P. believes
that there is a sufficient customer base willing to pay a premium price for a
superior tomato to justify the significant amount of money that will be
required for marketing and advertising necessary to promote the branded
tomato. Gargiulo L.P. intends to begin the marketing and advertising of its
branded tomato in the northeast and midwest regions of the United States in
February 1996. A successful branded tomato program would allow Gargiulo L.P.
to move a portion of its sales activities from the commodity fruit and
vegetable business directly to the retail markets. Ultimately, Gargiulo L.P.'s
strategy is to provide advertising, marketing and promotional services
directly to the major retail grocery chains, including setting up displays in
the stores, assisting store management in attractively positioning the
tomatoes in the produce area, and engaging in related activities pertaining to
the marketing of fresh tomatoes in the retail sector. Gargiulo L.P. believes
that retailers would embrace this service because it would contribute to their
profit. It would benefit Gargiulo L.P. by providing a consistent source of
sales for Gargiulo L.P.'s tomatoes and by reducing Gargiulo L.P.'s reliance on
the commodity markets. As one of the few vertically integrated commercial
fruit and vegetable growers in the industry, Gargiulo L.P. intends to use its
plant research capabilities, year round supply capabilities, geographic and
product line diversification, operational skill and professional management to
enable it to produce tomatoes suitable for sale directly to the retail market.
There can be no assurance that Gargiulo L.P.'s efforts with the branded tomato
will be successful. See "Risk Factors--Risks Associated with the Branded
Tomato Strategy."
 
  Tomato Production and Packing Locations. Gargiulo L.P. maintains growing
operations in and around Naples, Florida, Quincy, Florida, Mappsville,
Virginia, Santa Isabel, Puerto Rico, Firebaugh, California, and Sinaloa State,
Mexico. Each of these locations has the capability to pack the tomatoes for
shipment to repackers who put the tomatoes in the various types of packaging
demanded by the wholesalers, retailers, brokers and food service customers.
Gargiulo L.P. operates a repacking facility in Palmetto, Florida, in which it
repacks its own tomatoes, as well as tomatoes grown by other growers. If the
Collier Transaction is consummated, Gargiulo L.P. will acquire a repack
operation in Immokalee, Florida. In such event, Gargiulo L.P. intends to
discontinue its repack operations in Palmetto, Florida. Gargiulo L.P.,
together with its Mexican joint venture partner, maintains a distribution
center in Nogales, Arizona for the distribution of tomatoes grown in Mexico by
the joint venture.
 
  Set forth below is a table which illustrates Gargiulo L.P.'s ability, by
location, to produce tomatoes on a year round basis. The table also indicates,
for the last growing season at each location, the approximate net acres farmed
by Gargiulo L.P. by location, the approximate number of pounds of tomatoes
produced by Gargiulo L.P. and those produced by contract growers. The figures
set forth below may not be indicative of future results.

  Berries. During Fiscal 1995, Gargiulo L.P. grew approximately 3.8 million
flats of fresh strawberries and cooled approximately 7.7 million flats of
fresh strawberries through its own farming operations and pursuant to
relationships with contract growers. On a smaller scale, Gargiulo L.P. also
cools and markets raspberries, grown by itself and others, and blackberries
and blueberries grown by others.
 
  For the fiscal years ended June 30, 1993, 1994 and 1995, product revenues
from Gargiulo L.P.'s berry operations were approximately $9.5 million, $20.8
million, and $23.4 million, respectively, representing approximately 11.7%,
20.9% and 20.5%, respectively, of Gargiulo L.P.'s total revenues for those
fiscal years.
 
  Berry Production, Cooling and Warehousing Locations. Set forth below is a
table which illustrates Gargiulo L.P.'s ability, by location, to produce
berries. The table also indicates, for the last growing season at each

 Other Products
 
  Potatoes. In Fiscal 1995, Gargiulo L.P. grew and cultivated its first crop
of red potatoes in southwest Florida. The potatoes were subsequently harvested
during the winter months of Fiscal 1995. Gargiulo L.P.'s strategy is to
position itself to produce and market high quality fresh red potatoes during
the winter to take advantage of market timing and potentially stronger prices
in competition with potatoes obtained from storage by other producers.
 
  Peppers. During Fiscal 1995, Gargiulo L.P., as part of its joint venture
with a Mexican grower, produced and distributed red, yellow and green peppers
from Mexico from January through May. This represented Gargiulo L.P.'s initial
attempt to produce and distribute peppers.
 
  Chilean Winter Fruits. Since the mid 1980's, Gargiulo L.P. and the
Predecessors have imported and sold during the winter in the United States,
apricots, asparagus, grapes, nectarines, pears, plums and raspberries from
Chile and other South and Central American countries. Gargiulo L.P., through
its Chilean subsidiary, has interests, together with its Chilean partners, in
grape vineyards and nectarine orchards located in Chile. Gargiulo L.P.'s focus
is on importing and distributing high quality fruit during the winter months
in the United States and Canada.
 
 Marketing, Sales and Distribution
 
  Organization. Gargiulo L.P.'s marketing and sales efforts are principally
focused on the sale of tomatoes in the commodity markets. Marketing and sales
efforts are principally conducted by a telemarketing group.
 
                                      77

Pricing is typically based on factors such as USDA grade designation and fruit
size. The appearance of blemishes and other visual defects on the fruit
influences the USDA grade designation. In general, a greater number of defects
results in a lower grade and a lower price. Also, larger fruit commands a
higher price. Gargiulo L.P. generally makes weekly commitments for price,
though it sometimes enters into longer term fixed price contracts with respect
to berries.
 
  The sales group is currently focused on two principal products: (i) tomatoes
and vegetables; and (ii) berries and Chilean winter fruit. The principal
tomato customers for Gargiulo L.P.'s products are wholesalers, repackers and
brokers. A relatively small portion of tomatoes are sold directly to retailers
and food service accounts. The berry and fruit sales are somewhat more skewed
towards retail supermarkets and larger food service distributors and to a
lesser extent to wholesalers.
 
  Gargiulo L.P. has created a new marketing and sales group for the consumer
branded tomato program. The focus of this group is initially to conduct market
research to determine the viability and the direction of the branded program.
Upon implementation of the branded tomato strategy, this group will be
involved with the advertising program for the branded tomatoes, as well as
with the direct marketing of branded tomatoes to retailers and food service
accounts.
 
  Customers. During Fiscal 1995, no customer comprised more than 3% of
Gargiulo L.P.'s sales in any product area except for potatoes, which is
described in more detail below.
 
  The geographical distribution of Gargiulo L.P.'s sales is weighted to the
southeast and northeast portions of the United States. In Fiscal 1995,
Gargiulo L.P.'s top twenty customers accounted for approximately 20% of its
total sales revenue. Thirteen of such customers were wholesalers/repackers,
five were retail supermarkets and two were food service accounts.
 
  Gargiulo L.P. believes that during Fiscal 1995 approximately 30% of its
sales of berries were made to retail chain supermarkets, approximately 20%
were made to wholesale grocers, 10% were made to food service distributors,
approximately 30% are made to receivers and jobbers and 10% were sold to
others.
 
  In Fiscal 1995, Gargiulo L.P. entered into an arrangement to supply red
potatoes to Green Giant, a unit of Pillsbury, Inc. In the fiscal year ending
June 30, 1996, Gargiulo L.P. intends to market red potatoes through its own
marketing group.
 
  Virtually all of the produce sold or otherwise distributed by Gargiulo L.P.
is shipped by truck. The tomatoes produced in Puerto Rico and sold in the
continental United States and/or Canada are shipped by boat to the United
States, and then distributed by truck. Berries and asparagus produced in South
and Central America are air freighted to the United States. Other products
from Chile are shipped by boat to the United States. Tomatoes and berries are
generally sold in the open market free-on-board (F.O.B.) packing house.
 
 Competition
 
  Tomatoes. The tomato industry is characterized by numerous competitors.
Gargiulo L.P. believes that a small group of participants produces over one-
third of the tomatoes sold in the United States. Of these major producers,
only Gargiulo L.P. has a presence in each of Florida, Virginia, Puerto Rico,
California and Mexico. Gargiulo L.P. believes that because of the ease of
entry into and exit from the fresh tomato market, there are a large number of
competitors, and their identity may change from one growing season to the
next. In addition, Gargiulo L.P. believes it will face increasing competition
from Mexico due to the favorable climate and low labor costs. See "Risk
Factors--Competition."
 
  Berries. The berry industry is also characterized by a small number of
significant producers, including Gargiulo L.P., and numerous smaller
competitors. The principal product in the berry industry is strawberries,
followed by raspberries and blackberries.

 Trademarks and Licenses
 
  Gargiulo L.P. has federally registered the trademark NTGargiulo and is in
the process of registering the trademark "Gargiulo" and "Gargiulo Farms."
Applications for these trademarks are also pending in Canada, Mexico and
Puerto Rico. Gargiulo L.P. may also seek registration of other trademarks in
connection with its branded tomatoes. Gargiulo L.P. also maintains state
trademark registrations in Florida for the names "Beefstake" and "Neapolitan
Brand." Gargiulo L.P. maintains a state trademark registration for "Sunpic" in
Virginia.
 
 Research and Development
 
  Gargiulo L.P. began investing in research and development in the early
1980's through its affiliate, BHN Joint Venture ("BHN"). At its inception, the
primary focus of the research and development effort was the seed development
program, designed to increase tomato yield and increase fruit size. The seed
development program was the precursor to Gargiulo L.P.'s current research with
respect to developing a tomato with the sufficient attributes to qualify for
the branded tomato program. Research efforts remain concentrated on obtaining
better yield per acre, and producing a tomato with attributes such as better
taste, texture and color. Other tomato research goals include the development
of tomatoes which are resistant to insects, fungal and bacterial disease,
which have high temperature fruit set and which have improved flavor, firmness
and color, and the development of seeds designed to grow best in the diverse
climatic areas in which Gargiulo L.P. operates. The research program has
produced varieties that are grown by Gargiulo L.P. and which Gargiulo L.P.
believes have resulted in higher yields per acre than varieties available from
competing seed companies. This is accomplished through cross breeding and
selection of various trait combinations to produce parent seeds which can be
used to produce hybrid plants which have the desired characteristics. Gargiulo
L.P. entered into a Development/License Agreement with Monsanto dated as of
December 23, 1992, for the purpose of developing transgenic tomatoes for
commercial application. To date research relating to the transgenic tomato has
not yielded a tomato with a longer shelf life which can be produced on a
commercially feasible basis.
 
  Gargiulo L.P. believes that one of the competitive strengths of its tomato
research effort lies in the ownership of its own seed production facility in
Chile and its tight linkage to its commercial operations. This affords
Gargiulo L.P. the opportunity to screen large numbers of potential commercial
varieties in commercial field trials with direct feedback from the market.
 
  Gargiulo L.P. also conducts research on strawberries, although to a
significantly lesser extent than its research on tomatoes. Current strawberry
research efforts are concentrated in attempting to develop a proprietary
variety with improved taste and yield. Gargiulo L.P. currently estimates that
it is at least two years from developing a commercially marketable variety and
there can be no assurance that such a variety can actually be developed.
 
  For the fiscal years ended June 30, 1993, 1994 and 1995, Gargiulo L.P.
incurred research and development expenses of approximately $2.2 million, $3.5
million, and $3.9 million, respectively, which included approximately $1.6
million in each such year, except $800,000 in 1993, related to the Development
Agreement with Monsanto. While Gargiulo L.P. believes its research program has
yielded important benefits, the future success of the research is unknown and
is subject to substantial risk. See "Risk Factors--Risks Relating to Newco."
 
 Patents and Trade Secrets
 
  Gargiulo L.P. considers its tomato germplasm technology, which is needed in
the production of its proprietary hybrid tomato seed, to be trade secrets.
Gargiulo L.P. attempts to protect such trade secrets by use of security
measures with its key research employees. There is no assurance that Gargiulo
L.P. will be successful in protecting these valuable trade secrets or that
others will not develop tomato seeds having equal or superior characteristics.

 Government Regulations
 
  The federal regulatory agencies most involved in the predominant business of
Gargiulo L.P.--the production and marketing of fresh fruit and vegetables--are
the USDA and the FDA. The USDA sets standards for raw produce and governs its
inspection and certification. Under the Perishable Agricultural and
Commodities Act ("PACA"), the USDA exercises broad control over the marketing
of produce in domestic and foreign commerce, sets standards of fair conduct as
to representations, sales, delivery, shipment and payment for goods and
regulates the licensing of produce merchants and brokers. Gargiulo L.P.'s
growing operations are also subject to substantial oversight by the
Environmental Protection Agency (the "EPA") in matters ranging from the use of
fertilizers and pesticides to the condition of farmland and wetlands
protection. Of particular concern in this regard is the current investigation
by the EPA and other environmental regulators into the possible harmful
effects on the ozone layer of methyl bromide, a chemical widely used by
Gargiulo L.P. and other agricultural producers.
 
  In its more specialized research operations (primarily through BHN),
Gargiulo L.P. is subject to the coordinated oversight of the USDA, the FDA and
the EPA. These agencies have joint authority over all phases of the
development of certain genetically engineered plants, from research and
commercial applications through growing and transportation. The USDA also has
specific authority, under the Federal Seed Act, to oversee the quality and
labelling of commercial seed products, such as those developed by BHN.
 
  Through its extensive use of farm labor in its growing operations, Gargiulo
L.P. is subject to supervision by the United States Department of Labor, under
both the Fair Labor Standards Act and the Occupational Safety and Health Act;
and the prevalence of foreign workers in this sector of Gargiulo L.P.'s work
force necessarily involves oversight by the Immigration and Naturalization
Service.
 
  Almost every aspect of federal regulation is accompanied by regulation on
the state level, in each jurisdiction where Gargiulo L.P. has growing and/or
research operations. In particular in Florida, the South Florida Water
Management District regulates surface water management and irrigation water
withdrawals. Gargiulo L.P. must also, in its Mexican operation, comply with
the requirements of Mexican law, most importantly Mexico's environmental
protection law.
 
 Employees
 
  As of June 30, 1995, Gargiulo L.P. employed approximately 2,200 people, of
whom 200 were salaried full-time employees, 217 were full-time hourly farm and
packing house personnel, 8 were part-time employees, and approximately 1,775
were seasonal workers. Gargiulo L.P. believes relations with its employees are
good. None of Gargiulo L.P.'s work force is presently unionized, although
there is no assurance that unions, especially for farm workers, may not
attempt to unionize Gargiulo L.P.'s workers in the future.
 
 Properties
 
  Gargiulo L.P.'s principal properties presently consist of its executive
offices and sales offices and related packing facility located in Naples,
Florida; the BHN research facility in Bonita Springs, Florida; tomato packing
facilities in Palmetto, Florida; Quincy, Florida; Mappsville, Virginia; Santa
Isabela, Puerto Rico; and Firebaugh, California; administrative offices in
Watsonville, California; a sales office in Nogales, Arizona; and various owned
and leased farmland. Gargiulo L.P. owns or leases farmland in and around
Naples and Quincy, Florida; Watsonville, Oxnard, Santa Maria and Firebaugh,
California; Mappsville, Virginia; Santa Isabela, Puerto Rico; and Sinaloa
State, Mexico. See the tables included in "--Products" above for additional
information concerning the properties of Gargiulo L.P.
 
  Gargiulo L.P. primarily grows tomatoes and potatoes in and around the
Naples, Florida area and primarily grows tomatoes on its properties in and
around Mappsville, Virginia; Santa Isabela, Puerto Rico; Firebaugh,
California; and Sinaloa State, Mexico, although peppers and other vegetables
are also grown in Sinaloa State,

Mexico. Gargiulo L.P. primarily grows strawberries and raspberries on its
properties in Watsonville, Santa Maria and Oxnard, California.
 
  The majority of Gargiulo L.P.'s farmland is leased pursuant to relatively
short-term leases. Thus, the amount of farmland leased in any of the
geographic areas in which Gargiulo L.P. operates can vary from growing season
to growing season.
 
  In the event the Collier Transaction is successfully completed, Gargiulo
L.P. believes it will be in a position to sell certain property owned by
Gargiulo L.P. located in Collier County, Florida.
 
 Internal Control Systems
 
  Gargiulo L.P. and its predecessors were for many years private companies
controlled by the Gargiulo family and related parties. Internal control
systems of Gargiulo L.P. are considered adequate to identify material
misstatements in reporting financial statements. However, such systems could
be strengthened in several areas, including the segregation of duties in key
processes, such as procurement, payroll and cash, control over farm spending
as well as inadequate separation of Gargiulo L.P. business activities from
other Gargiulo family interests. While management of Gargiulo L.P. exercises a
high level of control, management is taking steps to improve such controls.
 
 Legal Proceedings
 
  Gargiulo L.P. is a defendant in two pending cases which involve personal
injury claims relating to a vehicle accident in which numerous migrant labor
workers being transported to the farm of Gargiulo & Dresick Associates (which
was being farmed under contract by Dresick Farms, Inc.) were killed or
injured. The two cases, Alvertano Alberto Jiminez; et. al. v. Gargiulo &
Associates; Pat Kreger, Inc., Manuel Vega; Robles Rios; Jesus Loza and Samuel
Santiago Vazquez, and Jose Vasquez; et. al. v. Gargiulo & Associates; Pat
Kreger, Inc., Manuel Vega; Robles Rios; Jesus Loza and Samuel Santiago
Vazquez, were both filed on October 18, 1995, in the United States District
Court for the Eastern District of California. The company hiring and
transporting such farm workers was Pat Kreger, Inc., an independent contractor
engaged by Dresick Farms, Inc. to arrange for migrant farm labor for the farm.
The plaintiffs allege that the vehicle in question was in violation of one or
more federal and state safety regulations governing farm labor vehicles. The
plaintiffs are seeking general damages, including compensation for pain and
suffering; special damages, including past, present and future medical
expenses; compensation for the loss of past and future income; and punitive
damages in an unspecified amount. Gargiulo L.P.'s insurance carriers have been
contacted regarding these lawsuits. It has not yet been determined whether
Gargiulo L.P.'s insurance will be sufficient to cover these claims, if any.
Gargiulo L.P. intends to vigorously defend itself against these claims.
Otherwise, Gargiulo L.P. currently is not a party to any pending legal
proceedings, other than ordinary routine litigation incidental to its
business.
 
 Certain Relationships and Related Transactions
 
  Gargiulo L.P. has numerous business relationships with affiliates. See
"Related Party Transactions."
 
 Management's Discussion and Analysis of Financial Condition and Results of
Operations
 
  Overview
 
  Gargiulo L.P. evolved from the consolidation, on December 23, 1992, of
several ventures held by four individuals and Tomato Investment Associates,
Inc., a wholly-owned subsidiary of Monsanto. Prior to the formation of
Gargiulo L.P., the financial statements of the entities owned by the four
principals (collectively, the "Predecessor Company") were combined because
they were under common control and management.
 
  Gargiulo L.P. is an agricultural producer, primarily of tomatoes and
strawberries, and is also engaged in various business activities related to
the packing, marketing, brokering, warehousing, distribution and breeding
research of fresh market vegetables and fruit.

 Fiscal Quarter Ended September 30, 1995 Compared to the Fiscal Quarter Ended
September 30, 1994
 
  Revenues
 
  Revenues for the first quarter of the 1996 fiscal year (the three month
period ending September 30, 1995) were $28.6 million, a 4.0% increase from the
corresponding quarter in the previous fiscal year. Tomato sales decreased 15%
to $10.6 million from $12.5 million, as lower prices were only partially
offset by increased volumes in both Virginia and California. The higher
volumes resulted primarily from an increase in acres harvested for the three
months ended September 30, 1995 compared with those for the comparable period
in 1994.
 
  Berry revenues increased 29.5% to $10.1 million from $7.8 million due to an
increase in flats harvested of approximately 300,000, or 21%, as a result of
increased acreage in the quarter ended September 30, 1995.
 
  Service revenues increased 7.5% to approximately $5.9 million due to the
increased tomato volumes in California and Virginia, partially offset by lower
berry volumes from outside growers.
 
  Cost of Revenues
 
  Cost of revenues in the quarter ending September 30, 1995 increased by 26.1%
to $29.7 million from $23.5 million. The increase in cost of revenues resulted
from increased volume and acreage of tomatoes in Virginia and California, and
increased berry farming acreage in California. Yields in California for both
tomatoes and berries were lower than in the prior year's quarter, increasing
costs per unit. Gross profit decreased by $5.0 million, falling to a negative
(3.7%) from 14.4% in the corresponding quarter of fiscal year 1995. $4.6
million of this decrease occurred in Gargiulo L.P.'s California tomato
operations, with the remainder occurring in Virginia.

  Selling, General & Administrative Expenses
 
  Selling, General & Administrative expenses for the quarter ending September
30, 1995 were $5.1 million, or 17.7% of revenues, up from $3.7 million, or
13.4% of revenues in the comparable prior period. This increase resulted from
expenditures related to the initial stages of the Gargiulo L.P.'s branded
tomato strategy.
 
  Interest Expense
 
  Interest expense increased to $605,000 from $383,000 in the prior year
quarter. This increase was due both to increased borrowings and higher
interest rates.
 
  Minority Interest Income (Expense)
 
  Income from minority interests was $1.3 million during the quarter ended
September 30, 1995, versus expense of $0.3 million in the prior year period.
The income from minority interests in the current period resulted primarily
from a $3.6 million loss incurred by Gargiulo L.P.'s tomato operation in
California. Expense from minority interests in the quarter ending September
30, 1994 primarily resulted from income earned during the period from the same
California tomato operation.
 
  Liquidity & Capital Resources
 
  Net cash provided from operations in the three month period ending September
30, 1995 was $2.3 million. Contributing to this amount were reductions in
receivables of $8.0 million and inventories of $1.5 million, as well as
depreciation and amortization expense of $1.2 million. These were partially
offset by the net loss for the period of $5.4 million and a reduction in
accounts payable, accrued expenses and amounts due to growers of $2.3 million.
 
  Capital expenditures in the period totalled $4.3 million.
 
  $0.5 million of cash was generated from financing activities. $3.6 million
of cash was raised through a financing, in the form of a lease obligation,
related to an aircraft acquisition. This was offset by repayments of term-
notes and capital lease obligations, and a reduction in the outstanding line
of credit balance, which collectively totalled $3.1 million.
 
 Fiscal 1995 Compared to Fiscal 1994
 
  Revenues
 
  Revenues in Fiscal 1995 increased 14.6% to $114.1 million from $99.5 million
in the year ended June 30, 1994 ("Fiscal 1994"). Tomato sales increased 19.5%
to $60.1 million from $50.3 million, primarily due to production gains in
Quincy, Florida and Puerto Rico, coupled with improved fresh tomato prices in
Quincy and Puerto Rico, and first time production in Virginia and Mexico. The
increase in production in Quincy and Puerto Rico was in response to a loss of
third party tomato volume and the need to maintain packing house efficiency.
New production in Virginia reflected Gargiulo L.P.'s desire to supply existing
East Coast customers with product during the summer months. The addition of a
Mexican operation afforded Gargiulo L.P. an opportunity to supply West Coast
markets and to insure supply when Florida production is down. A decrease in
Naples fresh tomato production was offset by a slight improvement in price
when comparing Fiscal 1995 to Fiscal 1994. The increase in tomato production
in Fiscal 1995 was slightly offset by a 17.7% decrease to $12.6 million from
$15.4 million in repack operations.
 
  Sales of fresh strawberries increased 12.1% to $23.4 million from $20.8
million due to an increase in strawberry production of approximately 400,000
flats. The increase in flat production was due primarily to an increase in
acreage farmed in California.
 
  Other product revenues increased 20.3% to $8.8 million from $7.3 million due
to the addition of potato and pepper product lines in Fiscal 1995.
 
                                      83
<PAGE>
 
  Service revenues remained relatively flat, increasing only $700,000 to $21.7
million in Fiscal 1995 from $21.0 million in Fiscal 1994. This modest increase
reflects the net result of an increase in strawberry cooling charges per flat,
off-set by a reduction in tomato packing charges resulting from fewer boxes
packed for third party growers.
 
  Cost of Revenues
 
  Cost of revenues in Fiscal 1995 increased 19.2% to $97.7 million from $82.0
million in Fiscal 1994. Gargiulo L.P.'s gross profit in Fiscal 1995 was 14.3%,
compared to 17.6% in Fiscal 1994. This increase in cost was primarily due to
costs associated with the increase in Gargiulo L.P.'s production of fresh
tomatoes and strawberries. While production levels did increase from Fiscal
1994 to Fiscal 1995, the decline in Gargiulo L.P.'s gross profit percentage
was attributable to start-up operations in Virginia during 1995, with lower
than normal margins, operating problems in the repack operations during 1995
and tomato production shortfalls in California because of weather, virus and
operating problems.
 
  Selling, General and Administrative Expense
 
  Selling, general and administrative expenses were $18.1 million in Fiscal
1995, a 17.7% increase from $15.4 million in Fiscal 1994. This increase was
principally due to Gargiulo L.P.'s increased level of operations. As a
percentage of total revenue, selling, general and administrative expenses were
15.9% and 15.5% in Fiscal 1995 and 1994, respectively. Selling, general and
administrative expenses as a percentage of sales increased slightly due to an
increase in general and administrative expenses necessary to support Gargiulo
L.P.'s expansion. Gargiulo L.P. is planning to enter into a branded tomato
market in Fiscal 1996 which is likely to result in significant initial
marketing, promotion, distribution and selling expenses.
 
  Interest (Expense) Income, Net
 
  Fiscal 1995 interest expense, net of interest income, was $1.7 million, a
97.9% increase over Fiscal 1994 interest expense, net of interest income, of
$0.9 million. The increase was due to an increase of $8.5 million in the
average borrowings outstanding during Fiscal 1995 as compared to Fiscal 1994
and an increase in the weighted average interest rate charged on such
borrowings from 6.1% to 7.8%.
 
 Fiscal 1994 Compared to Fiscal 1993
 
  Revenues
 
  Revenues in Fiscal 1994 increased 22.5% to $99.5 million from $81.2 million
for the 12 months ended June 30, 1993 ("Fiscal 1993"). Tomato sales increased
14.1% to $50.3 million from $44.1 million, primarily due to new operations in
California and an aggregate increase of 9.5 million pounds from the Naples and
Puerto Rico operations. Offsetting the increase in tomato production were
significant decreases in the market price of tomato crops from Naples and
Quincy. In addition, repack operations in Fiscal 1994 increased 22.7% to $15.4
million from $12.5 million for Fiscal 1993. This increase was primarily due to
a 5.9 million pound increase in repack operations in Fiscal 1994 versus Fiscal
1993.
 
  Fresh strawberry sales increased 118.9% to $20.8 million in Fiscal 1994 from
$9.5 million in Fiscal 1993 due to an increase in fresh strawberry production
of 1.6 million flats and an increase in market prices.
 
  Other product revenues increased 20.7% from $6.0 million in Fiscal 1993 to
$7.3 million in Fiscal 1994. This increase was principally due to additional
seed sales by BHN to a new customer in California.
 
  Service revenues remained relatively constant, decreasing $500,000 to $21.0
million in Fiscal 1994 from $21.5 million in Fiscal 1993. The reduction in
service revenues was the net result of a 1.2 million decrease in boxes packed
for third party tomato growers, which was partially off-set by a 4.5 million
increase in flats processed for third party strawberry growers.
 
                                      84
<PAGE>
 
  Cost of Revenues
 
  Cost of revenues in Fiscal 1994 increased 40.7% to $82.0 million from $58.3
million in Fiscal 1993. Gargiulo L.P.'s gross profit in Fiscal 1994 was 17.6%,
compared to 28.3% in Fiscal 1993. This increase in cost was primarily due to
costs associated with the increase in Gargiulo L.P.'s production of fresh
tomatoes and strawberries. Additionally, the decline in gross profit in Fiscal
1994 to 17.6% from 28.3% in Fiscal 1993 is attributable to a decline in the
market price for fresh tomatoes.
 
  Selling, General and Administrative Expenses
 
  Selling, general and administrative expenses were $15.4 million in Fiscal
1994, a 6.1% decrease from $16.4 million in Fiscal 1993. A significant portion
of the decrease resulted from various non-capitalizable expenses incurred in
Fiscal 1993 in connection with the formation of Gargiulo L.P. As a percentage
of total revenue, selling, general and administrative expenses were 15.5% and
20.2% in Fiscal 1994 and Fiscal 1993, respectively. As a percentage of
revenues, selling, general and administrative expenses decreased principally
due to the allocation of fixed overhead costs over a larger revenues base.
 
  Interest (Expense) Income, Net
 
  Fiscal 1994 interest expense, net of interest income, was $0.9 million, a
12.5% increase over interest expense, net of interest income, for Fiscal 1993
of $0.8 million. Interest expense for Fiscal 1994 and for Fiscal 1993 was $1.2
million in each period. Although no period to period fluctuation in expense
occurred, there was an increase of $2.4 million in the weighted average
borrowings outstanding during Fiscal 1994 as compared to Fiscal 1993, which
was offset by a decrease in the weighted average interest rate charged from
7.1% to 6.1%.
 
  Liquidity and Capital Resources
 
  During Fiscal 1995, Gargiulo L.P. financed its growth in sales and related
capital expenditures and other working capital requirements principally from
operating cash flow and from net proceeds from long term notes payable.
 
  Gargiulo L.P. has a $17.5 million line of credit facility with a financial
institution and, subject to certain limitations, a $10 million credit
agreement with Monsanto. As of June 30, 1995, Gargiulo L.P.'s borrowings under
the line of credit facility with the financial institution were $12.9 million.
No amounts were outstanding under the credit agreement with Monsanto. As of
June 30, 1995, Gargiulo L.P. had $4.6 million available for working capital
purposes under the line of credit facility with the financial institution and
the credit agreement with Monsanto.
 
  The line of credit facility with the financial institution bears interest at
the financial institution's LIBOR, as defined, plus 1.35% and expires on
November 15, 1996. The facility contains various restrictive covenants which
include minimum working capital requirements, a specified current maturity
coverage ratio and the maintenance of a specified ratio of total liabilities
to tangible net worth. The specified ratios of current maturity coverage and
of total liabilities to tangible net worth covenants had not been met as June
30, 1995; however, the lender has waived the requirements to maintain such
ratios through June 30, 1996. Gargiulo L.P. anticipates entering into a new or
modified credit facility arrangement before June 30, 1996.
 
  The credit facility with Monsanto will terminate upon the Effective Time and
all outstanding amounts due thereunder, including any amounts borrowed in
connection with the Collier Transaction, will be converted into loans under
the Gargiulo Credit Facility Agreement.
 
  Gargiulo L.P. has various long-term notes payable and certain capitalized
lease obligations with certain financial institutions and other third parties.
Many of these obligations contain various restrictive covenants. As of June
30, 1995 Gargiulo L.P. had not maintained certain ratios specified by a $2.3
million mortgage loan; however, the lender has waived the requirements to
maintain such ratios through June 30, 1996.
 
                                      85
<PAGE>
 
  Net cash provided by operating activities was $3.5 million in Fiscal 1995.
Contributing to cash provided by operating activities are $3.8 million of
depreciation and amortization, a decrease of $2.0 million in accounts
receivable and an increase of $4.5 million in accounts payable, accrued
expenses and amounts due to growers. Partially offsetting these amounts was
the net loss for Fiscal 1995 of $1.7 million, an increase in inventories of
$2.4 million and an increase in other operating assets of $1.8 million.
 
  Capital expenditures were approximately $6.5 million in Fiscal 1995. Major
items included in such total related to an expansion of the BHN research
program, an investment in the repack business, investment in a raspberry
program in California and expenditures in Virginia. The remainder was related
to investments and improvements.
 
  Gargiulo L.P.'s working capital increased from $14.8 million as of June 30,
1994 to $20.6 million as of June 30, 1995. Gargiulo L.P.'s line of credit
facility with a financial institution was renewed in December 1994. The
increase in working capital resulted from the extension of the due date of the
line of credit facility to November 15, 1996 and the related classification of
this facility as a long-term liability. The increase in working capital
resulting from the classification of the line of credit was partially offset
by reductions in working capital resulting primarily from capital expenditures
and long-term debt payments. Outstanding indebtedness of $26.7 million is
classified as long-term debt and therefore is not included for purposes of
calculating working capital.
 
COLLIER FARMS
 
 Business, Products and Distribution
 
  Collier Farms is a vertically integrated grower/shipper of fresh market
tomatoes and other vegetables based in southwest Florida. Business activities
include farming, packing and marketing fresh tomatoes and other vegetables, as
well as growing vegetable transplants. Collier Farms produces tomatoes during
the fall, winter and spring months and sells its product to repackers, brokers
and other intermediaries. Collier Farms' tomatoes are packed under the
"Collier Classic" label.
 
  Commodity produce sales are the primary source of revenues, comprising
approximately 85% of Collier Farms revenues over the past 5 fiscal years. The
majority of sales are to repackers and wholesale brokers who service retail
and food service customers in the U.S. and Canada.
 
  Collier Farms has a broad customer base with no single customer representing
more than 5% of sales. Approximately 30% of production occurs during the
months of October through December, 20% occurs during January and February,
and 50% during March through May. Vegetable transplant customers are primarily
located in central and south Florida, with only a small percentage of its
production shipped out of state.
 
  Virtually all of Collier Farms' fresh produce is shipped by truck.
Typically, it is the customer's responsibility to arrange for delivery,
although in a few cases Collier Farms will arrange for transportation for an
additional fee.
 
 Research and Development
 
  Research and development investments have been limited to less than $250,000
per year over the past five fiscal years. The three primary areas of focus
have been (i) variety evaluation, (ii) refinement of production practices, and
(iii) improved control of insects/pests, plant diseases and weeds. In
addition, considerable emphasis has been devoted to premium product
development during the past three years. Most research projects have been
entirely in-house and on-farm. However, cooperative research efforts with the
USDA, university scientists and private sector companies have been increasing.
Some of these latter projects are contractual in nature and involve longer
term impacts on farm activities.
 
 Government Regulations
 
  Collier Farms' operations include activities regulated under federal, state,
and local authorities in the same manner as Gargiulo L.P. See "Tomato
Investment Associates, Inc.--Garguilo L.P.--Government Regulations."

clerical and hourly production employees. There are currently no employees
working on a part-time basis.
 
  Seasonal harvesting labor averages 450 employees. These employees are
recruited by Collier Farms employed crew leaders. The I-9 processing is
contracted through Immokalee Ag Workers, Inc., a local company owned and
operated by area agribusiness companies, including Collier Farms. Immokalee Ag
Workers, Inc. has been in operation since 1987. Seasonal harvest employees are
paid by Collier Farms and are covered under Collier Farms' workers'
compensation policy.
 
  Seasonal employees for packing house operations average 230 workers. These
employees are recruited through Collier Farms' employment office. The I-9
processing is done through the State Job Service. Seasonal packing house
employees are paid by Collier Farms and are covered under Collier Farms'
workers' compensation policy.
 
 Properties
 
  The Collier Farms assets include four properties located in southwest
Florida. These properties are the sites of the two packing houses, proposed
seasonal labor housing and transplant nursery.
 
  Leased properties include areas which are used in the growing operations.
Leased properties are primarily comprised of lands owned by Collier
Enterprises and its affiliates. These areas have historically been used for
vegetable production and total approximately 11,000 acres. These properties
will be subject to a master lease agreement which will give Gargiulo L.P.
certain rights to utilize these properties. See "Tomato Investment Associates,
Inc.--Gargiulo L.P.--Acquisition of Collier Farms."
 
  Collier Farms leases two additional properties in central Florida. These
farms are used for early fall and late spring production of tomatoes and other
vegetables. Each location is approximately 200 net acres and is equipped with
low volume irrigation systems.
 
  The tomato and vegetable packing houses are located in Immokalee, Florida.
Product is transported from the field to the packing houses for packing and
cooling prior to shipment.
 
 Legal Proceedings
 
  Collier Farms is not a party to any pending legal proceedings, other than
ordinary routine litigation incidental to its business.
 
 Management's Discussion and Analysis of Financial Condition and Results of
Operations
 
  Overview
 
  Collier Farms is a vertically integrated grower/shipper of fresh market
tomatoes and other vegetables based in southwest Florida. Business activities
include farming, packing and marketing fresh tomatoes and other vegetables, as
well as growing and marketing vegetable transplants. Collier Farms produces
tomatoes during the fall, winter and spring months and sells its fresh produce
to repackers, brokers and other intermediaries. Collier Farms' tomatoes are
packed under the "Collier Classic" label.
 
  Product Revenues
 
  The principal product of Collier Farms is fresh tomatoes. Collier Farms
produced, packed and shipped approximately 60.2, 48.0 and 53.9 million pounds
of fresh tomatoes during the Fiscal years 1993, 1994 and 1995, respectively.
 
 
                                      87
<PAGE>
 
  The second largest product of Collier Farms is fresh peppers, including
bell, cubanelle and other specialty varieties. During the Fiscal years 1993,
1994 and 1995, Collier Farms produced, packed and shipped approximately 0.5,
0.6 and 0.4 million boxes of peppers, respectively.
 
  Other Revenues
 
  In connection with the production of fresh tomatoes, vegetables and
vegetable transplants, Collier Farms also provides packing, palletizing,
cooling, degreening, handling and sales services to third parties. Vegetable
transplants' sales and fees for packing, handling and sales services are
charged to outside growers. Palletizing, packing and degreening fees are
collected from produce customers, primarily repackers, brokers and other
intermediaries.

 Fiscal Quarter Ended September 30, 1995 Compared to Fiscal Quarter Ended
September 30, 1994
 
  Revenues
 
  Revenues in the quarter ended September 30, 1995 decreased 29.3% from
$495,000 in 1994 to $350,000. This variance is due to decreased volume of
transplant sales which has been caused by disease pressures during the current
fiscal year.
 
  Costs of Revenues
 
  Costs of revenues decreased to $802,000 from $805,000 from the three months
ended September 30, 1994 to the three months ended September 30, 1995. The
increase of costs of revenues as a percentage of revenues is a result in the
decrease in revenues discussed above.
 
  Selling, General and Administrative Expenses (including Interest Expense)
 
  Selling, general, and administrative expenses for fiscal 1995 increased by
8.6% ($105,000) from the three months ended September 30, 1994 to September
30, 1995 due to increases in staffing at the transplant nursery.
 
                                      88
<PAGE>
 
  Other Income
 
  Other income decreased $9,000 (6.5%) from the three months ended September
30, 1994 to September 30, 1995. The increase of other income as a percentage
of revenues is a result in the decrease in revenues discussed above.
 
  Net Income (Loss)
 
  As a result of the foregoing, net loss for the three months ended September
30, 1995 was $1.7 million, a $256,000 unfavorable variance over the three
months ended September 30, 1994.
 
 Liquidity and Capital Resources
 
  Collier Farms is part of a group of affiliated companies operating in
various industries. As part of the overall cash management system, excess cash
is distributed and cash deficiencies are funded on a daily basis and are
recorded as capital distributions and contributions, respectively.
Accordingly, capital distributions and contributions have been netted in the
accompanying combined statements of owners' equity.
 
  Collier Farms has two long-term notes payable. Both contain various
restrictive covenants. A mortgage note with a financial institution secured by
land and equipment (the "Land and Equipment Note") had a balance of $5.3
million at September 30, 1995. This note is currently the subject of a
forebearance agreement.
 
  During fiscal 1990, Collier Farms purchased a building and certain land
improvements using amounts borrowed from an affiliate (the "Affiliate"). In
connection with this purchase, the Affiliate executed a mortgage note payable
with a financial institution under which the building and land improvements
are pledged as collateral. Collier Farms' portion of the balance of the note
at September 30, 1995 was $6.5 million.
 
  Net cash used in operating activities was $4.7 million during the three
months ended September 30, 1995. Net cash used in investing activities totaled
$259,000 during the same period, and included $260,000 of capital expenditures
(discussed below). Net capital contributions of $4.4 million, advances from
related parties of $541,000, and proceeds from long-term debt of $116,000,
offset by $65,000 of payments on the related party notes payable resulted in
$5.0 million of net cash provided by financing activities.
 
  Capital expenditures in fiscal 1995 totaled $260,000 and were primarily made
for normal replacement of equipment such as tractors and plant trays, as well
as for the reconfigurations of the vegetable packing line and nursery
improvements. Collier's only significant commitments to incur capital
expenditures is a commitment to related parties to purchase certain assets
under specified conditions for approximately $425,000.
 
  Collier Farms' working capital increased $485,000 (23.5%) from September 30,
1994 to September 30, 1995, primarily because of $1.2 million increase in
inventories (due to increased acreage) offset by a $372,000 decrease in trade
receivables and a $397,000 decrease in related party receivables.
 
 Fiscal 1995 Compared to Fiscal 1994
 
  Revenues
 
  Revenues increased 15.5% from $22.0 million in Fiscal 1994 to $25.4 million
in Fiscal 1995. Tomato sales increased 21.0% from $14.3 million in Fiscal 1994
to $17.3 million in Fiscal 1995, primarily due to favorable market prices.
Approximately $1.0 million of the $3.0 million increase was due to price
increases. The remaining variance was due to an increase in production of 5.9
million pounds of tomatoes, the harvesting of which was made economically
viable due to the higher market prices.
 
  Total revenues for peppers decreased 7.8% from $5.1 million in Fiscal 1994
to $4.7 million in Fiscal 1995. Acreage in Fiscal 1995 was reduced by 50.5%
from Fiscal 1994; however, volume decreased by only 32.1% during the same
period as a result of improved yields from disease resistant varieties and
improved operating procedures. Market prices in Fiscal 1995 generally exceeded
Fiscal 1994 prices.
 
                                      89
<PAGE>
 
  Other revenues increased 29.6% from $2.7 million in Fiscal 1994 to $3.5
million, primarily as a result of increased packing and related services
provided to third party producers of tomatoes, squash and eggplant.
 
  Cost of Revenues
 
  Cost of revenues decreased in Fiscal 1995 from $21.1 million to $20.3
million, or a 3.8% decline. Collier Farm's gross profit was 20.3% in Fiscal
1995, compared to 4.2% in Fiscal 1994. The decrease in cost was primarily due
to a reduction in farmed acreage. The cost reduction was partially offset by
costs associated with heavy rains and higher repairs and maintenance expense
at the transplant nursery due to windstorm damage.
 
  Selling, General and Administrative Expenses (including Interest Expense and
Management Fees)
 
  Selling, general and administrative expenses for Fiscal 1995 decreased as a
percentage of sales due to stronger tomato markets. Actual expenses increased
$0.6 million, or 9.9% over Fiscal 1994's expenses. The increase was the result
of additional staffing and a 2.1% increase in average short term interest
rates on Collier Farms' variable rate debt.
 
  Other Income
 
  Other income decreased $1.3 million, or 55.1% from Fiscal 1994 to Fiscal
1995. Substantially all other income is generated through the sale of crops
produced under an annual agreement with an unrelated party.
 
  Liquidity and Capital Resources
 
  Collier Farms is part of a group of affiliated companies operating in
various industries. As part of the overall cash management system, excess cash
is distributed and cash deficiencies are funded on a daily basis and are
recorded as capital distributions and contributions, respectively.
Accordingly, capital distributions and contributions have been netted in the
accompanying combined statements of owners' equity.
 
  Collier Farms has two long-term mortgage notes payable which contains
various restrictive covenants. This mortgage note is with a financial
institution, secured by land and equipment (the "Land and Equipment Note") and
had an outstanding balance of $5.3 million at June 30, 1995. This note is
currently the subject of a forbearance agreement.
 
  During the fiscal year ended June 30, 1990, Collier Farms purchased a
building and certain land improvements using amounts borrowed from an
affiliate (the "Affiliate"). In connection with this purchase, the Affiliate
executed a mortgage note payable with a financial institution under which the
building and land improvements are pledged as collateral. Collier Farms'
portion of the balance of the note at June 30, 1995 was $6.5 million.
 
  Net cash provided by operating activities was $568,000 in Fiscal 1995. Net
cash used in investing activities totaled $1.2 million in Fiscal 1995, and
included $710,000 of capital expenditures (discussed below) and $609,000 of
advances to related parties. Net capital contributions of $1.0 million, offset
by $269,000 of payments on the related party notes payable resulted in
$741,000 of net cash provided by financing activities.
 
  Capital expenditures in Fiscal 1995 totaled $710,000 and were primarily made
for improvements to the vegetable transplant nursery, including relocation of
six greenhouses and construction of a new office facility. Collier Farms' only
significant commitment to incur capital expenditures is a commitment to
related parties to purchase certain assets under specified conditions for
approximately $425,000.
 
  Collier Farms' working capital decreased $3.9 million from June 30, 1994 to
June 30, 1995, primarily because the $5.3 million Land and Equipment Note was
classified as current at June 30, 1995.
 
 Fiscal 1994 Compared to Fiscal 1993
 
  Revenues
 
  Total revenues for Fiscal 1994 were $22.0 million, $9.3 million, or 29.6%,
less than total revenues for Fiscal 1993. Tomato revenues decreased 28.8% from
$20.1 million in Fiscal 1993 to $14.3 million in Fiscal 1994. Collier Farms
elected not to harvest some tomatoes when market prices fell below the cost of
harvesting, hauling and packing.
 
                                      90
<PAGE>
 
  Revenues from the sale of peppers for Fiscal 1994 were $5.1 million, $0.2
million, or 3.8%, below such revenues for Fiscal 1993. Although acreage
increased 49.2% from 630 to 940 net acres, volume increased by only 20.0% from
0.5 million to 0.6 million boxes.
 
  Other revenue for Fiscal 1994 was $2.7 million, $3.2 million, or 54.2%,
below other revenues for Fiscal 1993. Approximately 56% of the variance was
due to a decline in service revenues from outside growers and fresh produce
buyers. Declines in revenues from miscellaneous crops (e.g. watermelon and
squash, which were discontinued after Fiscal 1993) and vegetable transplants
also contributed to the variance.
 
  Cost of Revenues
 
  Cost of revenues for Fiscal 1994 decreased 9.5% to $21.1 million from $23.3
million in Fiscal 1993. Gross profit in Fiscal 1994 was 4.2% of total
revenues, compared to 25.5% in Fiscal 1993.
 
  Costs for tomato production decreased 12.3% during fiscal 1994, accounting
for 79.8% of the total decrease in cost of revenues. Although planted acreage
increased, resulting in increased variable farming costs, the reduction in
pounds of tomatoes harvested resulted in a significant reduction in harvest,
hauling and packing costs.
 
  Other costs of revenues decreased to $3.0 million from $4.4 million in
fiscal 1993. This was due primarily to discontinued miscellaneous crops (i.e.,
watermelon and squash) and the elimination of related incremental costs. The
remainder of the decline was due to reduced expenses at the vegetable
transplant nursery.
 
  Selling, General, and Administrative Expenses (including Interest Expense)
 
  Selling, general and administrative expenses were $6.0 million in Fiscal
1994, a 6.3% decrease from $6.4 million in Fiscal 1993. As a percentage of
total revenue, these expenses were 27.3% and 20.5% in Fiscal 1994 and Fiscal
1993, respectively. As a percentage of total revenue, selling, general and
administrative expense increased due to decreased revenues.
 
  Other Income
 
  Other income increased $0.6 million from $1.8 million in Fiscal 1993 to $2.4
million in Fiscal 1994. The increase was due primarily to an increase in
market prices for crops produced and sold under an annual agreement with an
unrelated party.

  Net cash used in operating activities was $858,000 in Fiscal 1994. Net cash
used in investing activities totaled $1.6 million in Fiscal 1994, and included
$1,100,000 of capital expenditures (discussed below) and $542,000 of advances
to related parties. Net capital contributions of $2.8 million, offset by
$279,000 of payments on the related party notes payable resulted in $2,433,000
of net cash provided by financing activities.
 
  Capital expenditures in Fiscal 1994 totaled $1,100,000 and were primarily
made for improvements to the vegetable transplant nursery, including
relocation of six greenhouses and construction of a new office facility.

                                 CALGENE, INC.
 
BUSINESS OF CALGENE
 
  Calgene is a biotechnology company that is developing a portfolio of
genetically engineered plants and plant products for the food, seed and
oleochemical industries. Calgene's research and business efforts are focused
in three core crop areas--fresh market tomato, edible and industrial plant
oils (canola) and cotton--where Calgene believes biotechnology can provide
substantial added commercial value in consumer, industrial and seed markets.
 
  Fresh Market Tomatoes. Calgene scientists have genetically engineered tomato
varieties with the FLAVR SAVR gene which delays softening and reduces spoilage
in order to enable Calgene to provide vine-ripened tomatoes with improved
taste to the $4 billion U.S. fresh tomato market throughout the year. Most
fresh market tomatoes are bred for durability and harvested before they have
begun to ripen, which reduces spoilage and handling damage, but at the expense
of taste and texture. In contrast, tomato varieties bred for premium flavor
and texture have been genetically engineered by Calgene scientists with the
FLAVR SAVR gene which delays softening and thereby reduces spoilage, even when
harvested vine-ripened. In May 1994, in response to Calgene's request, the FDA
announced its determination that the FLAVR SAVR tomato has not been
significantly altered with respect to safety or nutritive value when compared
to conventional tomatoes. This action by the FDA allowed Calgene to begin
commercialization of the FLAVR SAVR tomato, the world's first genetically
engineered whole food product. Calgene has also recently received regulatory
clearance to commercialize the FLAVR SAVR tomato in Canada and Mexico. Calgene
currently has 500 acres under contract located near its California packing and
distribution facility and 250 acres under contract in Mexico. Calgene is
currently selling premium quality, vine-ripened tomatoes with the FLAVR SAVR
gene under its MacGregor's brand.
 
  In view of the production scale-up difficulties that it has encountered,
Calgene plans to temporarily curtail its tomato growing operations in the
Spring of 1996 until it is able to complete the development of varieties of
FLAVR SAVR tomatoes that have enhanced commercial agronomic qualities. Calgene
intends to focus its tomato operations on the plant breeding activities
necessary to develop such enhanced varieties of its genetically-engineered
tomatoes, but there can be no assurance that such efforts will be successful
or will not be discontinued by Newco.
 
  After the Effective Time, Newco plans to consolidate CalFresh with the
Gargiulo tomato business under the management of TIA. Newco plans to market a
full line of tomatoes nationwide, including the premium MacGregor branded
tomato line of Calgene (if and when enhanced varieties are developed) and the
Gargiulo L.P. branded tomato line proposed to be marketed by Gargiulo L.P.
There can be no assurance that Newco will sell genetically engineered tomatoes
or will not encounter difficulties in integrating the businesses of CalFresh
and Gargiulo L.P. or that it will be successful in marketing either branded
tomato line. See "Risk Factors--Risks Applicable to the Branded Tomato
Strategy" and "Risk Factors--Risks Associated with Production of Genetically
Engineered Tomatoes."
 
  Plant Oils. Calgene is developing genetically engineered rapeseed oils with
a broad range of food and industrial applications. Rapeseed is an efficient
oil producing plant, has certain biological characteristics that make it a
good candidate for genetic engineering, and is adaptable to a broad range of
growing regions. Calgene scientists have genetically engineered canola
varieties that produce substantial quantities of laurate, an important
ingredient in detergents that is not naturally present in canola or other non-
tropical oil plants. In July 1995 Calgene sold one million pounds of Laurical
canola oil and is currently contracting for 10,000 to 15,000 acres of
commercial production for October 1995. Calgene is also currently conducting
its eighth season of field trials with canola plants that have been
genetically engineered to produce oil with increased stearate levels, creating
a potential substitute for hydrogenated oils in margarine, shortening and
confectionery products. Calgene's subsidiary, Calgene Chemical, manufactures
and distributes plant oil-based chemicals, and supplies Mobil Oil with plant
oil-based biodegradable fluids. Calgene has also established strategic
relationships with Procter & Gamble, Unilever and Pfizer to address potential
commercial opportunities for plant oil products.

<PAGE>
 
  Cotton. Calgene's cotton genetic engineering program focuses on reducing
farmers' growing costs through the development of cotton varieties that
require less pesticides, and cotton varieties that produce natural colors.
U.S. cotton farmers spend annually over $200 million on herbicides and $225 to
$400 million on insecticides. Herbicide resistant and insect resistant cotton
varieties have the potential to enable cotton farmers to significantly reduce
the total volume of herbicides and insecticides applied, resulting in
substantial savings in production costs, improved yields and benefits to the
environment. Calgene believes that the cost savings to farmers will enable
Calgene to price genetically engineered seed varieties at a premium to current
cotton seed prices. In 1995 Calgene introduced two genetically engineered
cotton varieties ("BXN(TM) cotton"), which are resistant to the herbicide
bromoxynil. Bromoxynil is produced and sold by Calgene's strategic cotton
partner, Rhone-Poulenc Agrochimie ("Rhone-Poulenc"), a leading agrichemical
company. The BXN(TM) cotton seed was sold at a 45% price premium over
Calgene's non-genetically engineered cotton seed. Calgene has also conducted
field trials since 1991 with BXN(TM) cotton varieties that are genetically
engineered for resistance to Heliothis, the principal cotton insect pest.
Calgene scientists are in the early stages of developing cotton varieties
having natural colors which will reduce or eliminate the need for dyeing and
provide unique color-fastness. Calgene intends to produce identity-preserved
genetically engineered cotton and sell premium-priced colored cotton fiber to
fabric, apparel and houseware manufacturers. Calgene is currently selling
genetically engineered BXN (TM) cotton seed through its subsidiary Stoneville
Pedigreed Seed Company.
 
  Calgene's business strategy is to build operating businesses in its core
crop areas to facilitate the market introduction of genetically engineered
proprietary products and to maximize the long-term financial return from such
products. Implementation of this strategy will provide Calgene with direct
access to markets where it intends to sell seed that has been engineered with
value-added agronomic traits, and to markets where it intends to sell fresh
and processed plant products having improved quality traits or cost of
production advantages, or both.
 
EXECUTIVE COMPENSATION
 
  Compensation Committee Interlocks and Insider Participation
 
  During the fiscal year ended June 30, 1995, the members of the Human
Resources Committee (the "Committee") were Messrs. Baker, Baeder, Helinski and
Stinnett, John Vohs was a director and member of the Committee until his
resignation on November 17, 1994. None of the members has ever been an officer
or employee of Calgene or any of its subsidiaries. During Fiscal 1995, there
were no Committee "interlocks" within the meaning of the SEC rules, and there
continue to be no such "interlocks."
 
  Mr. Salquist, Chairman of the Board and Chief Executive Officer,
participated in portions of meetings of the Committee at the invitation of the
Committee and made various proposals to the Committee at its request. In
addition, at the Committee's direction, Mr. Salquist has set the cash
compensation of certain other executives.

  Change of Control Employment Agreements
 
  Messrs. Salquist, Stacey and Motroni have entered into Change of Control
Employment Agreements, dated as of July 19, 1995, with Calgene. Each Agreement
becomes effective only upon a Change of Control (as defined) of Calgene and
provides that, if the employment of the officer is terminated by Calgene
without Cause (as defined) or by the officer for Good Reason (as defined)
within the three-year term of the Agreement or if (in the case of Mr.
Salquist) he resigns upon the six-month or three-year anniversaries of the
effective date of the Agreement, the officer shall receive severance benefits
that include a payment equal to 2.99 times his base salary and average bonus
for the prior three fiscal years. Such severance benefits are subject to
reduction to the extent necessary to prevent the recipient from incurring
liability for excise taxes and Calgene from incurring nondeductible
compensation expense. For purposes of such agreements, a Change of Control
would include the closing of the proposed transaction pursuant to which
Monsanto would acquire a 49.9% equity interest in the combined business of
Calgene and Gargiulo L.P.

  Report on Repricing of Options
 
  On November 16, 1994, the Committee approved a stock option exchange program
(the "Exchange Program"), pursuant to which officers, employees and certain
other holders holding incentive stock options and non-statutory options under
Calgene's 1981 Stock Option Plan and 1991 Stock Option Plan, (collectively,
the "Stock Plans") were given the opportunity, on November 16, 1994, to
exchange such options for new options.
 
  Because of significant declines in the market value of Calgene's Common
Stock, most outstanding options in November 1994 were exercisable at prices
which substantially exceeded the market value of the Common Stock. In view of
such declines in market value and in keeping with Calgene's philosophy of
utilizing equity incentives to motivate and retain qualified employees, the
Committee felt it was important to regain the incentive intended to be
provided by options to purchase shares of Calgene's Common Stock. The need for
such incentives was particularly acute in light of Calgene's difficult
financial position at the time and the significant workforce reductions that
had been implemented.
 
  Under the Exchange Program, holders of stock options on November 16, 1994
(excluding options granted on October 31, 1994), which were granted under the
Stock Plans and which have an exercise price greater than $7.50 per share (the
"Existing Options") were offered the opportunity to request that Calgene issue
new options ("New Options") having an exercise price equal to $7.50 (the "Base
Exercise Price"). New Options granted with respect to Existing Options which
were vested as of November 16, 1994 were subject to an additional vesting
period of between 2 and 30 months.
 
                                      96
<PAGE>
 
  A total of 150 option holders (constituting 93% of eligible option holders),
holding options to purchase an aggregate of 1,268,081 shares of Common Stock
under Existing Options (which would be options to purchase the same aggregate
number of shares of Common Stock under the New Options), elected to
participate in the Exchange Program.
 
  The New Options modify the exercise price and, for some optionees, the term
(since the new vesting schedule was extended beyond the original expiration
date) of the Existing Options to which each relates and will be issued under
and governed by the respective Stock Plan under which such options are
originally granted. Therefore, other than the different exercise price and the
extended term, the option agreements relating to the New Options will be
substantially the same as the option agreements for the Existing Options that
they replace.

BOARD COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
 Composition and Functions of the Committee
 
  The Human Resources Committee (referred to in this report as the
"Committee") consists of four non-employee directors: Robert Baker, Donald
Baeder, Donald Helinski and Carl Stinnett.
 
  The Committee performs the functions of a compensation committee. The
Committee considers and makes recommendations to the Calgene Board concerning
general compensation policies and employee benefit plans and specifically
recommends salary levels and bonus awards for certain senior executive
officers, including the Chief Executive Officer. The Committee also
administers Calgene's stock option plan and has sole authority to grant
options to officers. The Committee's executive salary and bonus
recommendations for Fiscal 1995 were approved by the Calgene Board without
modifications.
 
 Objectives of Executive Compensation Policy
 
  The objectives of Calgene's executive compensation policy are to:
 
  . set executive compensation at levels sufficient to attract, retain and
    motivate highly qualified executive personnel;
 
  . align the interests of management and the stockholders by making a
    substantial portion of executive compensation dependent on the success of
    Calgene, as measured by long-term appreciation in the market price of
    Calgene's Common Stock; and
 
  . balance considerations of individual achievements each year with
    Calgene's financial and non-financial performance.
 
  In furtherance of these objectives, Calgene's executive compensation policy
provides for a combination of base salary, cash incentive bonus awards and
long-term stock options. Calgene also makes matching contributions under its
401(k) savings plan for all employees that participate, including its
executive officers. Calgene does not provide its executives with significant
perquisites.
 
 Salary
 
  In determining its recommendation to the Calgene Board concerning the salary
of senior executive officers, the Committee considers published data from
annual surveys of executive compensation at other biotechnology companies.
With the survey data as a reference point, the Committee makes adjustments
based on its evaluation
 
                                      97
<PAGE>
 
of Calgene executives' individual levels of experience, responsibility and
past performance. The Committee also takes into consideration each executive's
comparability with other Calgene executives. The Committee typically gives
considerable weight to the views of the Chief Executive Officer and the Chief
Operating Officer with respect to executive salaries other than their own.
Annual salary adjustments normally become effective in the month of July.
 
  For Fiscal 1996, the Committee recommended and the Board of Directors
approved an increase in Mr. Salquist's salary to $275,000 effective July 1,
1995.
 
 Incentive Bonuses
 
  The Committee each year sets target maximum cash bonus levels for certain
senior executives and delegates to the Chief Executive Officer the
responsibility to do so for more junior executives. Fiscal 1995 bonus award
target amounts for senior executives ranged from 33% to 16% of their salaries.
The Committee has formulated five performance categories: (1) individual
contribution toward achieving annual corporate objectives, and the degree to
which Calgene achieves the objectives; (2) achievement of divisional
nonfinancial objectives; (3) achievement of financial objectives; (4)
contribution to building the organization of Calgene's tomato, oils and cotton
business units; and (5) corporate leadership. These categories include
performance criteria that can be measured against objective standards, and
also criteria that involve subjective determinations. Each of these categories
is assigned a weight for a particular executive based upon that executive's
role and responsibilities in Calgene. Each senior executive's performance
under those categories provides a guideline for the Committee's fiscal year-
end recommendation to the Calgene Board as to what portion, if any, of the
target maximum bonus will be awarded to a particular executive. The Committee
takes into account the overall corporate financial results and cash position
of Calgene in determining the total bonuses to be awarded.
 
  For Fiscal 1995, bonuses were granted to Messrs. Baum and Knauf.
 
  Stock Options
 
  The granting of stock options is the principal method available to the
Committee to align the interests of the executive officers with those of the
stockholders. The option will reward the executive only if the market price of
the Common Stock appreciates over the option term and the executive remains
employed by Calgene over the vesting period. Options granted to executive
officers generally have a ten-year term, vest over a period of five years and
may be exercised at a price per share equal to the market price on the date of
grant. Stock options are granted to at least some executive officers each
year, as well as to numerous other employees. The number of shares in an
option grant reflects the executive's position at Calgene, stock options
granted to the executive in the past and the executive's potential
contribution to the success of Calgene. In granting stock options to senior
executive officers, the Committee has not followed any set of fixed
guidelines.
 
  For Fiscal 1995, the Committee recommended and the Board of Directors
approved the grant of an option to Mr. Salquist to purchase 100,000 shares.
 
  Other Matters
 
  The Committee has considered the potential impact of Section 162(m) of the
Internal Revenue Code, which disallows a tax deduction to any publicly-held
corporation for compensation (including non-cash compensation) exceeding $1
million in any year paid to any of the five most highly compensated executive
officers, unless such compensation meets certain requirements. The cash
compensation of each of Calgene's executive officers is well below $1 million.
The principal non-cash compensation of Calgene executives is from stock
options. Calgene is generally entitled to a tax deduction if an executive
exercises a nonqualified stock option or disposes of shares acquired from the
exercise of an incentive stock option before the required holding period has
ended. The Committee believes that Calgene stock options either will meet the
requirements of Section 162(m) or will not result in the loss of significant
tax deductions. Taking this into account, as well as Calgene's large tax loss
 
                                      98
<PAGE>
 
carryover and the reduced flexibility from a change to the stock option plan
to conform to the requirements of Section 162(m), the Committee has not
recommended any change to the stock option plan. However, the Committee may
consider imposing annual exercise limitations in some future option grants to
executives if Calgene would otherwise be deprived of significant tax benefits.
 
  The Calgene Board approved Change of Control Agreements for Roger H.
Salquist, Roderick N. Stacey and Michael J. Motroni. These agreements provide
for the payment of severance compensation in the event of termination of their
employment in connection with any future Change of Control of Calgene.
 
  This report is submitted by the following directors, who constituted all the
members of the Committee during Fiscal 1995, with the exception of John Vohs,
who resigned as a Calgene Board and Committee member during Fiscal 1995.

  Stock Performance Graph
 
  The graph below compares the five-year cumulative total returns for Calgene
Common Stock, the Nasdaq Composite Index and a select Peer Group Index of
Companies identified by Calgene. The graph assumes a $100 investment on June
30, 1990, in Calgene Common Stock and in each of the two indices, and assumes
the reinvestment of all dividends paid by companies represented in the two
indices. The representation of the component companies in the indices is
weighted according to their respective market capitalizations at the end of
each period for which cumulative returns are shown in the graph. The selected
peer group index consists of the following agricultural biotechnology
companies known by the Company to have their shares traded on the Nasdaq
National Market: Mycogen Corporation, Ecogen Inc., DNA Plant Technology
Corporation and Biosys Inc. Calgene has selected a different index from the
Piper-Jaffray Agri-Biotechnology Index (the "Piper-Jaffray Index"), which the
Company used for the immediately preceding fiscal year, because the Piper-
Jaffray Index has been discontinued. As a result, Calgene is unable to compare
its total return with that of the Piper-Jaffray Index. The graph is in this
Proxy/Prospectus in accordance with the rules of the SEC and is not
necessarily indicative of future performance.

    DESCRIPTION OF NEWCO STOCK OPTION PLANSAND EMPLOYEE STOCK PURCHASE PLAN
 
  In December 1995, the Board of Directors of Newco adopted, and the
stockholders subsequently approved, the Newco 1996 Stock Option Plan covering
5,000,000 shares of Newco Common Stock. Newco will assume, upon the Effective
Time, Calgene's 1991 Stock Option Plan (the "1991 Option Plan") and 1990
Employee Stock Purchase Plan (the "Calgene Stock Purchase Plan"). As of
December 31, 1995, only 365,943 shares were available under the 1991 Option
Plan.
 
 Summary of the 1996 Stock Option Plan
 
  The principal features of Newco's 1996 Stock Option Plan (the "Option Plan")
are summarized below.
 
  Purpose
 
  The purpose of the Option Plan is to attract and retain the best available
personnel for positions of substantial responsibility, to provide additional
incentive to employees, officers and directors of Newco and to promote the
success of Newco's business.
 
  Administration
 
  The Option Plan is administered by a committee of Newco's Board of Directors
consisting solely of non-employee directors (references hereinafter to the
Board of Directors shall include such committee). The interpretation and
construction of any provision of the Option Plan is within the sole discretion
of the Board, whose determination is final and conclusive. Members of the
Board receive no additional compensation for their services in connection with
the administration of the Option Plan.
 
  Eligibility
 
  The Option Plan provides that options may be granted to employees, officers,
directors and consultants of Newco and its subsidiaries, provided that
incentive stock options may be granted only to employees (including officers
and directors who are also employees). The Board of Directors or the Chief
Executive Officer, as authorized by the Board and within specified limits,
selects the optionees and determines the number of shares to be subject to
each option. In making such determination, there is taken into account the
duties and responsibilities of the employee, the value of the employee's
services, the employee's present and potential contribution to the success of
Newco, the anticipated number of years of future service of the employee and
other relevant factors.
 
  Option grants under the Option Plan to directors who are not employees of
Newco are automatic and non-discretionary in accordance with the provisions of
the Option Plan. Each non-employee director is automatically granted an option
to purchase 10,000 shares at the time of his or her first election to the
Board of Directors. On the date of the Annual Meeting in each calendar year,
each non-employee director who is elected at such meeting is automatically
granted an option to purchase 3,000 shares (except for an eligible director
who is first elected to the Board of Directors at or within three months prior
to that meeting).
 
  The Option Plan does not provide for a maximum or minimum number of shares
of Common Stock which may be granted under options to any employee.
 
  Terms of Options
 
  Each option granted under the Option Plan is evidenced by a written stock
option agreement between Newco and the optionee. The Board of Directors
determines when options may be exercisable. In general, an option becomes
exercisable in increments during its term. Options may have a maximum term of
ten years from the date of grant. The current form of option agreement
provides for a ten-year term. No option may be exercised after the expiration
of its term.
 
                                      106
<PAGE>
 
  The exercise price of options granted under the Option Plan is determined by
the Board of Directors and, in the case of incentive stock options or options
granted to directors who are not employees, may not be less than 100% of the
fair market value of the Common Stock on the date the option is granted.
Depending on the terms of the particular option, payment for shares issued
upon exercise may consist of cash, check, personal promissory note, surrender
of shares owned by the optionee or such other consideration as determined by
the Board of Directors and permissible under Delaware law.
 
  If an optionee's employment with Newco is terminated for any reason, the
option shall be exercisable within such period of time as is determined by the
Board of Directors (generally, thirty days, under the proposed form of option
agreement) to the extent that such option rights were exercisable on the date
of termination, and thereafter the option shall terminate. Longer periods are
permitted in the event of termination of employment due to death or
disability. An option is not transferable by the optionee, other than by will
or the laws of descent and distribution.
 
  The option agreement may contain such other terms, provisions and conditions
not inconsistent with the Option Plan as may be determined by the Board of
Directors. The Board of Directors may, with the consent of any optionee,
cancel or amend the terms (including price) of any outstanding option.
 
  Changes in Capitalization
 
  In the event of changes in the Common Stock by reason of a stock dividend,
split-up or combination of shares, reclassification, recapitalization, merger,
consolidation, reorganization or liquidation, the Newco Board shall make such
adjustments in the option price and the number and class of shares subject to
the option under the Option as it shall deem appropriate. In the event of any
merger of Newco or any acquisition of all or substantially all of its assets
or stock, or any liquidation of Newco, the Newco Board shall have the power to
make arrangements for the substitution of new options for any options then
outstanding under the Option Plan or for the assumption by Newco's successor
of any such options or for the acceleration of the expiration date of options.
 
  Amendment and Termination
 
  The Board of Directors may at any time amend or terminate the Option Plan.
To the extent necessary to comply with rules promulgated under Section 16 of
the Exchange Act or to comply with Sections 421 and 422 of the Internal
Revenue Code and any regulations thereunder, any amendment made to the Option
Plan will require approval of the stockholders of Newco. The Option Plan will
terminate in any event in 2005. Termination will not impair any option
previously granted without the optionee's consent.
 
  Federal Income Tax Consequences
 
  Incentive Stock Options. No taxable income will be recognized by an optionee
upon the grant or exercise of an incentive stock option (provided that the
difference between the option exercise price and the fair market value of the
stock on the date of exercise must be included in the optionee's "alternative
minimum taxable income"), and no corresponding expense deduction will be
available to Newco. Generally, if an optionee holds shares acquired upon the
exercise of incentive stock options until the later of (i) two years from the
grant of the option and (ii) one year from the date of transfer of the
purchased shares to him or her (the "Statutory Holding Period), any gain to
the optionee upon a sale of such shares will be treated as capital gain. The
gain recognized upon the sale of the stock is the difference between the
option price and the sale price of the stock. The net federal income tax
effect on the holder of incentive stock options is to defer, until the stock
is sold, taxation of any increase in the stock's value from the time of grant
to the time of exercise, and to cause all such increase to be treated as
capital gain.
 
  If the optionee sells the shares prior to the expiration of the Statutory
Holding Period, he or she will realize taxable income at ordinary income tax
rates in an amount equal to the lesser of (i) the fair market value of the
 
                                      107
<PAGE>
 
shares on the date of exercise less the option price, or (ii) the amount
realized on the sale less the option price, and Newco will receive a
corresponding business expense deduction. Any additional gain will be treated
as long-term capital gain if the shares are held for more than one year prior
to the sale and as short-term capital gain if the shares are held for a
shorter period. If the optionee sells the stock for less than the option
price, he or she will recognize a capital loss equal to the difference between
the sale price and the option price. The loss will be a long-term capital loss
if the shares are held for more than one year prior to the sale and a short-
term capital loss if the shares are held for a shorter period.
 
  Nonstatutory Stock Options. No taxable income is recognized by the optionee
upon the grant of a nonstatutory option. The optionee must recognize as
ordinary income in the year in which the option is exercised the amount by
which the fair market value of the purchased shares on the date of exercise
exceeds the option price (and Newco may be required to withhold an appropriate
amount for tax purposes). If the optionee is a person who is required to file
reports pursuant to Section 16(a) of the Exchange Act, then upon the exercise
of an option within six months from the date of grant no income will be
recognized by the optionee until six months have expired from the date the
option was granted, and the income then recognized will include any
appreciation in the value of the shares during the period between the date of
exercise and the date six months after the date of grant (unless the optionee
makes an election under Section 83(b) of the Code to have the difference
between the exercise price and fair market value on the date of exercise
recognized as ordinary income as of the time of exercise). Newco will be
entitled to a business expense deduction equal to the amount or ordinary
income recognized by the optionee, subject to the limitations of Section
162(m) of the Code. Any additional gain or any loss recognized upon the
subsequent disposition of the purchased shares will be a capital gain or loss,
and will be a long-term gain or loss if the shares are held for more than one
year.
 
 Summary of 1991 Stock Option Plan
 
  The 1991 Option Plan was adopted by the Calgene Board in 1991 and approved
by the stockholders of Calgene 1991. The 1991 Option Plan was amended by the
Calgene Board and the stockholders of Calgene in 1994 to increase the number
of shares authorized for issuance thereunder by 1,250,000 shares to an
aggregate of 2,500,000 shares.
 
  As of December 31, 1995, options to purchase 1,996,697 shares of Calgene
Common Stock were outstanding under the 1991 Option Plan, 137,360 shares had
been issued upon exercise of options granted under the 1991 Option Plan and
365,943 shares were available for future grants under the 1991 Option Plan.
 
  The 1991 Option Plan is substantially similar in all respects to the 1996
Option Plan described above.
 
 Summary of 1990 Employee Stock Purchase Plan
 
  The 1990 Employee Stock Purchase Plan (the "Purchase Plan") authorizes the
issuance of up to an aggregate of 500,000 shares of Common Stock to
participating employees. As of December 31, 1995, 383,912 shares were
available under the Purchase Plan.
 
  The Purchase Plan will be administered by the Newco Board, which will be
authorized to decide questions of eligibility and to make rules and
regulations for the administration and interpretation of the Purchase Plan.
With certain exceptions, all employees, including officers, employed by Newco
or its subsidiaries are eligible to participate in the Purchase Plan. Non-
employee directors are not eligible to purchase shares under the Purchase
Plan.
 
  The Purchase Plan provides for consecutive offerings to employees to
purchase Common Stock under the Purchase Plan as determined by the Board of
Directors from time to time ("Offerings"). An employee may elect to have a
minimum of 2% and a maximum of 10% deducted from his or her regular salary for
this purpose but in no event may an employee purchase more than 5,000 shares
or invest more than $25,000 in any one Offering. The price at which an
employee's option is exercised is the lower of (i) 85% of the last reported
price of the
 
                                      108
<PAGE>
 
Common Stock on the Nasdaq National Market on the day that the Offering
commences or (ii) 85% of the last reported price on the day that the Offering
terminates.
 
  The Newco Board may at any time terminate or amend the Purchase Plan.
However, if approval of an amendment is required by Section 423 of the Code or
Rule 16b-3 of the Exchange Act, such amendment may not be effected without
such approval. The Purchase Plan requires that all amounts in the accounts of
participating employees be promptly refunded upon termination of the Purchase
Plan.
 
  Because participation in the Purchase Plan is voluntary, it is not possible
to determine the number of shares of Newco Common Stock to be purchased by any
particular current executive officer, by all current executive officers as a
group or by non-executive employees as a group. Based solely upon the last
reported sales price of Calgene Common Stock on the Nasdaq National Market on
December 15, 1995 ($4.875 per share), the fair market value of the Common
Stock available under the Purchase Plan as of December 31, 1995 was $1.87
million.
 
  Federal Income Tax Consequences
 
  The Purchase Plan is intended to qualify as an "employee stock purchase
plan" as defined in Section 423 of the Code, which provides that an employee
will not realize any federal tax consequences when such employee joins the
Purchase Plan, or when an Offering ends and such employee receives shares of
Newco Common Stock. An employee must, however, recognize income or loss on the
difference, if any, between the price at which he or she sells the shares and
the price he or she paid for them. If an employee has owned shares purchased
under the plan for more than one year, disposes of them at least two years
after the date an Offering commenced, and the market price of the shares on
the date of sale is equal to or less than the purchase price under the
Purchase Plan, he or she will recognize a long-term capital loss in the amount
equal to the price paid over the sale price. If an employee has owned shares
for more than one year, more than two years has lapsed from the date the
Offering commenced, and the market price of the shares on the date of sale is
higher than the purchase price under the Purchase Plan, the employee must
recognize ordinary income in an amount equal to the lesser of (a) the fair
market value of the shares on the day the Offering commenced over the price
paid, or (b) the excess of the amount actually received for the shares over
the purchase price. Any further gain would be treated as long-term capital
gain.
 
  If an employee sells shares purchased under the plan prior to holding them
for more than one year or prior to two years from the date the Offering
commenced, he or she must recognize ordinary income in the amount of the
difference between the price he or she paid and the market price of the shares
on the date of purchase and Newco will receive an expense deduction for the
same amount, subject to the limitation of Section 162(m) of the Code. The
employee will recognize a capital gain or loss on the difference between the
sale price and the market price on the date of purchase. Newco will not be
entitled to a tax deduction upon either the purchase or sale of shares under
the Purchase Plan if the holding period requirements set forth above are met.
The Purchase Plan is not qualified under Section 401(a) of the Code.

                      DESCRIPTION OF NEWCO CAPITAL STOCK
 
GENERAL
 
  The authorized capital stock of Newco presently consists of 80 million
shares of Newco Common Stock and 10 million shares of Preferred Stock.
 
  The following are summaries of the terms of the Newco Common Stock and Newco
Preferred Stock. Such summaries do not purport to be complete.
 
COMMON STOCK
 
  Newco is authorized to issue up to 80 million shares of Common Stock, $0.001
par value per share. Holders of Newco Common Stock are entitled to one vote
for each share held on all matters submitted to a vote of stockholders, except
that under certain circumstances stockholders may cumulate their votes in the
election of directors. Holders of Newco Common Stock are entitled to receive
ratably such dividends, if any, as may be declared by the Newco Board out of
funds legally available therefor, subject to any preferential dividend rights
of any outstanding Preferred Stock. Upon the liquidation, dissolution or
winding up of Newco, the holders of Newco Common Stock are entitled to receive
ratably the net assets of Newco available after the payment of all debts and
other liabilities and subject to the prior rights of any outstanding Preferred
Stock. Holders of Newco Common Stock have no preemptive or conversion rights.
The outstanding shares of Newco Common Stock are, and the shares to be issued
in connection with the Merger will be, when issued and paid for, fully paid
and nonassessable. The rights, preferences and privileges of holders of Newco
Common Stock are subject to, and may be adversely affected by, the rights of
the holders of shares of any series of Preferred Stock which Newco may
designate and issue in the future.
 
PREFERRED STOCK
 
  The Newco Board is authorized, subject to any limitations prescribed by law,
from time to time to issue up to an aggregate of 10 million shares of
Preferred Stock, $.001 par value per share, in one or more series, each of
such series to have such rights and preferences, including voting rights,
dividend rights, conversion rights, redemption privileges and liquidation
preferences, as shall be determined by the Newco Board. The rights of the
holders of Newco Common Stock will be subject to, and may be adversely
affected by, the rights of holders of any Preferred Stock that may be issued
in the future. Issuance of Preferred Stock, while providing desirable
flexibility in connection with possible acquisitions and other corporate
purposes, could have the effect of making it more difficult for a third party
to acquire, or of discouraging a third party from attempting to acquire, a
majority of the outstanding voting stock of Newco. Except as described below,
Newco has no present plans to issue any shares of Preferred Stock.
 
  The Newco Board has authorized a series of Preferred Stock designated as the
Series A Redeemable, Non-Voting Preferred Stock (the "Newco Series A Preferred
Stock"). The Newco Series A Preferred Stock will have no voting rights, except
as otherwise required by law; will not be convertible into common stock; will
have a liquidation preference of $1.00 per share; and will be redeemable by
Newco at any time up to December 31, 1999 for $1.00 per share. At Closing,
Monsanto and Warren R. Haug will exchange 499 shares and 501 shares,
respectively, of Calgene Series A Preferred Stock for the same number of
shares of Newco Series A Preferred Stock.
 
DELAWARE ANTI-TAKEOVER LAW
 
  Newco is subject to the provisions of Section 203 of the Delaware Law.
Section 203 prohibits a publicly held Delaware corporation from engaging in a
"business combination" with an "interested stockholder" for a period of three
years after the date of the transaction in which the person became an
"interested stockholder," unless the business combination is approved in a
prescribed manner. A "business combination" includes mergers, asset sales and
other transactions resulting in a financial benefit to the "interested
stockholder." Subject
 
                                      110
<PAGE>
 
to certain exceptions, an "interested stockholder" is a person who, together
with affiliates and associates, owns (or within three years did own) 15% or
more of the corporation's voting stock.
 
CERTAIN CHARTER AND BY-LAW PROVISIONS
 
  Newco has included in its Certificate of Incorporation provisions to
indemnify its directors and officers to the fullest extent permitted by
Section 145 of the Delaware Law. Newco's Certificate of Incorporation also
includes provisions to eliminate the personal monetary liability of its
directors to Newco or its stockholders for breaches of fiduciary duty, except
as specifically provided under Delaware Law. Newco believes that these
provisions are necessary to attract and retain qualified persons as directors
and officers.
 
TRANSFER AGENT AND REGISTRAR
 
  The transfer agent and registrar for Newco's Common Stock is The First
National Bank of Boston, Post Office Box 644, Boston, Massachusetts 02102.
Telephone number: (617) 575-2537.
 
                       COMPARISON OF STOCKHOLDER RIGHTS
 
  The rights of holders of Calgene Common Stock are substantially identical to
the rights of holders of Newco Common Stock, subject to the right of Monsanto
to designate certain Directors of Newco and approve certain actions. Certain
provisions of the Stockholders Agreement have been incorporated into Newco's
Certificate of Incorporation. See "The Reorganization Agreement and Related
Agreements--The Stockholders Agreement."
 
                              NO APPRAISAL RIGHTS
 
  Holders of Calgene Common Stock do not have rights of appraisal under the
Delaware Law in connection with the Reorganization.
 
                                 LEGAL MATTERS
 
  The validity of the shares of Newco Common Stock to be issued in connection
with the Merger will be passed upon for Newco by Hale and Dorr.

reasonable basis for our opinion.

1. DESCRIPTION OF CALGENE II, INC.
 
  Calgene II, Inc. ("Newco"), a Delaware corporation, was incorporated on
November 21, 1995. Newco is a holding company that was established by Monsanto
Company ("Monsanto") and Calgene, Inc. ("Calgene") to effect the transactions
contemplated by the Reorganization Agreement dated October 13, 1995 between
Monsanto and Calgene (collectively, the "Reorganization"). Upon consummation
of the Reorganization, Newco will own (i) all of the outstanding shares of
capital stock of Calgene, which shall be renamed "Calgene Technology
Corporation," and (ii) all of the outstanding shares of capital stock of
Tomato Investment Associates, Inc. and Produce Related Technology of Monsanto
Company ("TIA"), a wholly-owned subsidiary of Monsanto, which upon
consummation of the Reorganization will own the entire equity interest in
Gargiulo L.P. Consummation of the Reorganization is subject to the approval of
Calgene shareholders, the pre-transaction filing and waiting period
requirements applicable to the Reorganization under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended, the effectiveness of the Newco
Registration Statement described below, compliance with applicable state
securities laws, and other customary closing conditions. Newco has not engaged
in any operating activities since its inception.
 
  Upon consummation of the Reorganization, Newco will be renamed "Calgene,
Inc." and Monsanto will own 49.9% of the then outstanding shares of Newco
Common Stock and the holders of Calgene Common Stock outstanding immediately
prior to the Reorganization will own 50.1% of the then outstanding shares of
Newco Common Stock.
 
  Newco will file with the Securities and Exchange Commission a Registration
Statement on Form S-4 under the Securities Act of 1933, as amended, with
respect to the shares of Newco's Common Stock to be issued to the shareholders
of Calgene pursuant to the Reorganization Agreement.
 
  The consolidated balance sheet includes the accounts of Calgene II, Inc. and
its wholly-owned subsidiary, Calgene Acquisition Corp. All intercompany
accounts and transactions have been eliminated in consolidation.

                         INDEPENDENT AUDITORS' REPORT
 
To Tomato Investment Associates, Inc.
 and Produce Related Technology of
 Monsanto Company:
 
  We have audited the accompanying combined balance sheets of Tomato
Investment Associates, Inc. ("TIA") (a wholly-owned subsidiary of Monsanto
Company) and Produce Related Technology of Monsanto Company (See Note 1) as of
June 30, 1995 and 1994, and the related statements of operations,
shareholder's equity, and cash flows for each of the three years in the period
ended June 30, 1995. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
 
  We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.
 
  In our opinion, such combined financial statements present fairly, in all

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
  Technology is a carve-out of Monsanto technology costs and include all
direct and indirect costs associated with developing the technology listed

exercise of its options to acquire 100% Gargiulo, L.P.) and 100% of Calgene.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Investment in Equity Affiliate--The Company's investment in the Partnership
is accounted for under the equity method of accounting for investments.
 
  Goodwill--Goodwill which is included in the Investment in Equity Affiliate
line of the balance sheet totaled $25.6 million and $12.8 million net
accumulated amortization of $2.4 million and $1.1 million at June 30, 1995 and
1994, respectively and is amortized on a straight-line basis over its
estimated useful life, 20 years. TIA evaluates the periods of amortization
continually and has determined there are no later events or circumstances
which would warrant revision to its original estimate of useful life.
 
  Research and Development--Research and development costs are expensed as
incurred.
 
  Income Taxes--The Company is a "C" Corporation. Income taxes have been
provided for in accordance with the provisions of Statement of Financial
Accounting Standards No. 109, Accounting for Income Taxes.
 
  Related Party--All employee costs of Technology have been funded by
Monsanto. TIA has no employees and, therefore, no direct or indirect employee
salary or benefit costs have been incurred.
 
3. INVESTMENT IN EQUITY AFFILIATE
 
  TIA's equity investment in the Partnership represents substantially all of
TIA's existing assets.

4. INCOME TAXES
 
  The Company's operations are included in the consolidated U.S. Federal and
certain combined and separate state income tax returns of Monsanto. The
balance of refundable income taxes and deferred income taxes are due from/to
Monsanto, since Monsanto pays all taxes on the Company's behalf. Deferred
income taxes have been determined for temporary differences between the
financial reporting basis and tax basis of the assets and liabilities.
Temporary differences primarily result from depreciation, equity income from
an unconsolidated affiliate, and differences in recognition of assets written-
off.
 
  The components of income tax benefit (expense) charged are:

5. DEVELOPMENT AGREEMENT
 
  As part of the partnership agreement dated December 23, 1992 between TIA and
the Partnership, TIA entered into a development agreement for the primary
purpose of developing transgenic tomatoes for commercial application in the
production and sale of fresh market and processing tomatoes. The development
agreement requires TIA to carry out, at its expense, its portion of the
development plan through December 31, 1998. The development agreement further
requires that the Partnership pay TIA in five annual payments of $1,880
beginning on December 31, 1992 and ending on December 31, 1996. An additional
payment of $1,410 shall be received upon the latter of the development of a
tomato germplasm which exhibits certain attributes (defined in the development
agreement as "Commercial Level Performance") or December 31, 1995. Upon the
marketing and sale of the development tomato, the TIA will receive an
additional payment to be determined based on the date that both Commercial
Level Performance is achieved and the necessary regulatory approvals are
obtained:
 
  . If on or before December 31, 1996, TIA will receive an additional payment
    of $4,230.
 
  . If after December 31, 1996, but on or before December 31, 1997, Monsanto
    will receive an additional payment of $2,115.
 
  . If after December 31, 1997, but on or before December 31, 1998, Monsanto
    will receive an additional payment of $1,410.
 
  Advance payment on development agreement was $1,723 and $1,410 at June 30,
1995 and 1994, respectively. Additionally, recognition of the advance payments
against technology expense was $1,567, $1,567, and $783 for the years ended
1995, 1994, and 1993, respectively.
 
6. SUBSEQUENT EVENTS
 
  Monsanto and Calgene, Inc. entered into an Agreement and Plan of
Reorganization on October 13, 1995. The Agreement is subject to approval by
the Calgene, Inc. shareholders. Among other commitments, if approved by the
Calgene shareholders, TIA is required to exercise its options to acquire the
remaining interest in the Partnership and to contribute its interest in the
Partnership to Calgene (Note 1).

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
  The Agreement and Plan of Reorganization further requires that prior to the
formation of Calgene, the Development Agreement (Note 5) will be amended to
eliminate the TIA obligation to carry out its commitments defined in the
development plan and the Partnership is relieved of its obligation to make
payments to TIA. Calgene will receive a fully paid-up license to the
technology under the Development Agreement. The accompanying financial
statements have not been adjusted for any changes in amounts or classification
of assets or liabilities which may be required once the transaction is
consummated.
 
  On October 18, 1995, the Partnership became a defendant in two pending
lawsuits which involve personal injury claims by the families of three migrant
labor workers who were killed and by seven migrant labor workers who were
injured in a vehicle accident. The company hiring and transporting such farm
workers was an independent contractor engaged to arrange for migrant farm
labor for a Partnership farm. The plaintiffs allege that the vehicle in
question was in violation of one or more federal and state safety regulations
governing farm labor vehicles. The Partnership's insurance carriers have been
contacted regarding these lawsuits, but it has not yet been determined whether
the Partnership's insurance will be sufficient to cover these claims, if any.
Accordingly, the outcome of this litigation and the amount of damages, if any,
that may ultimately be incurred cannot be determined and no provisions for any
liability has been made in the accompanying combined financial statements.

                         INDEPENDENT AUDITORS' REPORT
 
Gargiulo, L.P. and Subsidiaries:
 
  We have audited the accompanying consolidated balance sheets of Gargiulo,
L.P. (formerly known as NTGargiulo, L.P.) and Subsidiaries (collectively
referred to as the "Partnership") as of June 30, 1995 and 1994 and the related
consolidated statements of operations, partners' capital, and cash flows for
the years then ended and for the period from December 23, 1992 (Date of
Commencement) to June 30, 1993. These consolidated financial statements are
the responsibility of the Partnership's management. Our responsibility is to
express an opinion on these consolidated financial statements based on our
audits. We did not audit the consolidated financial statements of Gargiulo
P.R., Inc. (formerly known as NTGargiulo P.R., Inc. and as South Coast Fruit
and Vegetable Company, Inc.), a subsidiary consolidated herein, which
statements reflect total assets constituting approximately 15% and 17% of
total consolidated assets as of June 30, 1995 and 1994, respectively, and
total revenues constituting approximately 5%, 6% and 8% of total consolidated
revenues for the years ended June 30, 1995 and 1994 and for the period from
December 23, 1992 (Date of Commencement) to June 30, 1993, respectively. Those
statements were audited by other auditors whose report has been furnished to
us, and our opinion, insofar as it relates to the amounts included for
Gargiulo P.R., Inc., is based solely on the report of such other auditors.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to
obtain reasonable assurance about whether the consolidated financial
statements are free of material misstatement. An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits and the
reports of other auditors provide a reasonable basis for our opinion.
 
  In our opinion, based upon our audits and the reports of the other auditors,
such consolidated financial statements present fairly, in all material
respects, the financial position of the Partnership as of June 30, 1995 and
1994 and the results of its operations and its cash flows for the years then
ended and for the period from December 23, 1992 (Date of Commencement) to June
30, 1993 in conformity with generally accepted accounting principles.

NTGargiulo, Inc. and Affiliates:
 
  We have audited the accompanying combined statements of operations,
stockholders' equity and cash flows of NTGargiulo, Inc. and Affiliates
(collectively referred to as the "Predecessor Company"), all of which are
under common ownership and management, for the period from July 1, 1992 to
December 22, 1992. These combined financial statements are the responsibility
of the Predecessor Company's management. Our responsibility is to express an
opinion on these combined financial statements based on our audit. We did not
audit the consolidated financial statements of Gargiulo P.R., Inc. (formerly
known as NTGargiulo P.R., Inc. and as South Coast Fruit and Vegetable Company,
Inc.), an affiliate combined herein, which statements reflect total revenues
constituting 3% of total combined revenues for the period from July 1, 1992 to
December 22, 1992. Those statements were audited by other auditors whose
report has been furnished to us, and our opinion, insofar as it relates to the
amounts included for Gargiulo P.R., Inc., is based solely on the report of
such other auditors.
 
  We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the combined financial statements
are free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audit and the
report of other auditors provide a reasonable basis for our opinion.
 
  In our opinion, based upon our audit and the report of the other auditors,
such combined financial statements present fairly, in all material respects,
the results of operations and cash flows of the Predecessor Company for the
period from July 1, 1992 to December 22, 1992, in conformity with generally
accepted accounting principles.
 
  As discussed in the notes to the consolidated/combined financial statements,
on December 23, 1992 the Predecessor Company contributed substantially all of
its net assets and operations to Gargiulo, L.P. (formerly known as NTGargiulo,
L.P.), a Delaware limited partnership.

1. GENERAL, ORGANIZATION, BASIC OF PRESENTATION AND SUMMARY OF SIGNIFICANT
   ACCOUNTING POLICIES
 
  General--Gargiulo, L.P. (formerly known as NTGargiulo, L.P.), a Delaware
limited partnership, and Subsidiaries (collectively referred to as the
"Partnership") is an agricultural producer, primarily of tomatoes and berries,
and is engaged in various business activities related to the packaging,
marketing, brokering, warehousing, distribution and breeding research of fresh
market fruit and vegetables. Operations are principally in Florida,
California, Puerto Rico, and Mexico and the corporate headquarters are in
Naples, Florida. Although not significant, the Partnership also has operations
in Chile, Arizona and Virginia. Successful operations are highly dependent
upon climatic conditions, not only in the Partnership's farming areas, but in
other international agribusiness locations. Additionally, because the
Partnership has foreign operations, it is susceptible to economic and
political events which may occur in those foreign countries.
 
  The following information is provided to understand the evolution of the
organization and the basis of presentation of the consolidated/combined
financial statements:
 
  Predecessor Company Organization--As of June 30, 1992, the Predecessor
Company consists of the following affiliates, all of which have common
ownership and management:
 
  .NTGargiulo, Inc. ("NTGI")
  .Coastal Berry Corporation ("CBC")
  .Gulf Coast Packaging Corporation ("GULF")
  .Home Grown Farms, Inc. ("HGF")
  .Naples Fruit and Vegetable Company ("NFV")
  .Miracle Farms, Inc. ("MIRACLE")
  .Old Fort Tomato Growers, Inc. ("OLD")
  .Gargiulo P.R., Inc. ("GPR") (formerly known as NTGargiulo P.R., Inc. and
     as South Coast Fruit and Vegetable Company, Inc.)
  .Duroy, Inc. ("DUROY")
 
  Additionally, as of June 30, 1992, the following affiliates have been
consolidated herein with one or more of the above entities, and applicable
minority interest liability recorded, because they are majority-owned by the
Predecessor Company:
 
  .BHN Joint Venture ("BHN") is a partnership in which NTGI acquired an
     additional 20% interest during 1992. The transaction, which brings
     NTGI's interest in BHN to 80% as of June 30, 1992, was accounted for as
     a purchase and the excess cost over fair market value of the net assets
     acquired of $624,475 is being amortized over 5 years.
  .Gulf Coast Farms Joint Venture ("GCFJV") is a partnership wholly owned by
     HGF and NFV.
 
  .Superior Plant Company ("SUPERIOR") is a partnership in which NTGI owns a
     75% interest.
 
  Also, as of June 30, 1992, the following unconsolidated affiliates are not
majority-owned by the Predecessor Company and therefore are accounted for
under the equity method:
 
  .NTHG Joint Venture--50% owned by NTGI (during the year ended June 30,
     1994, the Partnership acquired the remaining 50% interest in NTHG Joint
     Venture)
 
  .Hortifruit, Inc.--50% owned by NTGI

          NTGARGIULO, INC. AND AFFILIATES (THE "PREDECESSOR COMPANY")
 
              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
  Transitional Period--Subsequent to June 30, 1992, but prior to December 23,
1992, the transactions and events described below occurred. Each of the
mergers were among entities under common control and management, and
therefore, were accounted for similar to a pooling of interests, whereby the
accounts were recorded at historical carrying values by the surviving entities
and adjustments to the equity accounts were recorded retroactively:
 
  .GULF, HGF, NFV and GCFJV merged with and into NTGI.
 
  . DUROY merged with and into a newly-formed entity, Gargiulo, G.P., Inc.
    (formerly known as NTGargiulo, G.P., Inc.) ("GP"). The GP was capitalized
    substantially by assets contributed to the GP by the Predecessor Company.
    Such contributed assets were recorded by the GP at carryover basis, and a
    significant portion was later contributed to the Partnership as described
    below.
 
  . MIRACLE and OLD's net assets were not contributed to the Partnership.
 
  . GPR formed a wholly-owned subsidiary, South Coast Vegetable Realty
    Company, Inc. ("SCVRC"), and acquired a 33.33% interest in TGL
    Enterprises.
 
  Partnership Organization--The Partnership was formed on December 23, 1992 by
NTGI, CBC, GP and an unrelated third party, Tomato Investment Associates, Inc.
("TIA"). GP is the general partner and the other entities are limited
partners. In forming the Partnership, NTGI, CBC and GP contributed
substantially all of their net assets, including NTGI's ownership interest in
its subsidiaries, to the Partnership. In addition, certain stockholders of
NTGI and CBC contributed, on behalf of NTGI and CBC, their ownership interests
in GPR and their interests in certain entities discussed below. NTGI, CBC, and
GP are under common control and management and collectively control the
operations of the Partnership. As a result of this common control and
management, the Partnership recorded the net assets and ownership interests
contributed by, or on behalf of, NTGI, CBC, and GP at their historical
carrying values. TIA contributed cash. The Partnership's operations are
allocated to each partner based on their respective ownership interests. On
July 29, 1994, GP's ownership percentage increased from 2% to 3% and the other
entities became 97% limited partners. Effective June 30, 1995, CBC merged into
NTGI.
 
  On December 23, 1992, ownership in the following entities were contributed
to the Partnership by the stockholders of NTGI on behalf of NTGI. The
Partnership controls these entities:
 
  . Agricola Purutun, Limitada ("PURUTUN"), a 99.9% owned Chilean limited
    liability entity. By agreement, the Partnership shares in 90% of the
    profits and losses of PURUTUN.
 
  . GPM, S.A., a Chilean corporation. During the year ended June 30, 1995,
    GPM, S.A. changed its name to NTGargiulo S.A. ("NTGSA") and in a related
    transaction, the Partnership's ownership interest in NTGSA increased from
    75% to 99.99% and NTGSA's ownership interest in the following entities
    decreased from 50% to 37.5%.
 
  . Montemayor S.A. ("MONTEMAYOR")
 
  . Exportadora Agricola Topfrut, S.A. ("TOPFRUT") and its (a) 99.9% owned
    subsidiary (Industria Hortofruticola Friofruta S.A.) and (b) 50% owned
    subsidiary (Agricola La Roca, S.A.)
 
  The above-described transaction, which did not change the Partnership's
underlying interest in the net assets of NTGSA, also included the
Partnership's acquisition of a .01% ownership interest in both Collague S.A.
and Inversiones Manley S.A. Additionally, MONTEMAYOR and TOPFRUT are
unconsolidated affiliates, because they are not majority-owned by the
Partnership, and are therefore accounted for under the equity method. As a
result of the existence of certain contingencies, as of June 30, 1994, the
Partnership's investment in NTGSA was carried at a nominal amount. As of June
30, 1995, such contingencies have been resolved and NTGSA is a consolidated
subsidiary of the Partnership.

  Subsequent to December 23, 1992, but prior to June 30, 1993, the Partnership
formed NTGargiulo and Dresick Associates ("DRESICK"), a 66.7% owned
partnership.
 
  On January 23, 1995, the Partnership acquired for $7,000, a 99.9% interest
in Sociedad Comercial El Melon, Limitada ("SOCOMEL"), a Chilean entity, in a
transaction accounted for as a purchase. On the date acquired, SOCOMEL had no
significant assets or liabilities.
 
  During the year ended June 30, 1995, the Partnership formed Gargiulo Mexico,
L.L.C. ("MEX"), a 99% owned limited liability company, with the remaining 1%
owned by the GP. The following entities (which are 50% owned by MEX) are
unconsolidated affiliates, because they are not majority-owned by the
Partnership, and are therefore accounted for under the equity method:
 
  .Del Campo NTGargiulo, L.L.C. ("DCLLC")
 
  .Del Campo NTGargiulo Mexico, S. de R.L. ("DCSRL")
 
  Basis of Presentation--The combined financial statements of the Predecessor
Company include the accounts of NTGI and its affiliates, all of which have
common ownership and management. Subsidiaries which are majority-owned by NTGI
and its affiliates have been consolidated with NTGI and its affiliates.
Subsidiaries that are not majority-owned by NTGI and its affiliates are
accounted for under the equity method.
 
  The consolidated financial statements of the Partnership include the
accounts of the Partnership and subsidiaries majority-owned by the
Partnership. Subsidiaries that are not majority-owned by the Partnership are
accounted for under the equity method.
 
  All significant intercompany balances and transactions have been eliminated
in the preparation of the consolidated/combined financial statements.
 
  Unconsolidated Affiliates--The following summary of condensed balance sheets
and statements of operations information are presented for the unconsolidated
affiliates:

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
  The following is a summary of significant accounting policies:
 
  Cash and Cash Equivalents--All highly liquid instruments with an initial
  maturity of three months or less when acquired are considered cash and cash
  equivalents for the purposes of preparing the statements of cash flows.
 
  Inventories--Supplies and seeds inventories are stated at the lower of cost
  (first-in, first-out method) or market. Growing crops are stated at the
  lower of cost or market.
 
  Property and Equipment--Property and equipment are stated at cost.
  Depreciation is provided over the estimated useful lives of the assets on
  the straight-line and accelerated methods. Leasehold improvements are
  amortized over the term of the related lease or the estimated useful life
  of the improvement, whichever is shorter.
 
  Leases that transfer substantially all the benefits and risks of ownership
  are accounted for as an acquisition of assets and incurrence of
  obligations. Accordingly, capitalized leased assets are recorded as
  property and equipment and the present value of the future minimum lease
  payments are recorded as a liability. Amortization of such assets is
  computed using the straight-line method over the estimated useful lives of
  the related assets.
 
  The estimated useful lives of the assets are as follows:
 
<TABLE>
    <S>                                                               <C>
    Buildings and leasehold improvements.............................   30 years
    Machinery and equipment.......................................... 4-20 years
    Capitalized lease equipment......................................  2-5 years
</TABLE>
 
  Organizational Costs--Organizational costs, included in other assets,
  represent professional fees incurred in forming the Partnership.
  Organizational costs are being amortized on the straight-line method over
  five years.
 
  Customer List--Customer list, included in other assets, represent certain
  rights acquired by the Partnership in connection with the purchase of
  certain assets from an unrelated third party. Customer list is being
  amortized on the straight-line method over five years.
 
  Revenue Recognition--Product revenues are recognized at the time title
  transfers to the buyer and the product is delivered. Service revenues are
  recognized at the time the service is performed.
 
  Research and Development--Research and development costs are expensed as
  incurred ($3,905,594, $3,456,254, $1,579,182 and $661,132 for the years
  ended June 30, 1995 and 1994 and the periods from December 23, 1992 to June
  30, 1993 and July 1, 1992 to December 22, 1992, respectively).
 
  Included in the preceding amounts is development/license agreement expense
  (see Note 7) which, during the years ended June 30, 1995 and 1994 and the
  period from December 23, 1992 to June 30, 1993 amounted to $1,566,667,
  $1,566,667 and $783,383, respectively.
 
  Income Taxes--The Partnership's federal taxable income and expenses, with
  the exception of GPR and its wholly-owned subsidiary, SCVRC, flow directly
  to the partners and are not taxed at the Partnership level. Therefore, as
  of June 30, 1995, the Partnership's net assets exceed the partners' equity
  in the Partnership by approximately $4,500,000.
 
  GPR is a U.S. corporation authorized to do business in Puerto Rico and,
  accordingly, is subject to U.S. and Puerto Rico income taxes. For U.S.
  income tax purposes, GPR has elected to be taxed under Section 936 of the
  Internal Revenue Code, which allows an income tax credit equal to the
  portion of U.S. income taxes attributable to the earnings derived from
  sources within Puerto Rico and from qualified investment income. Under
  Puerto Rico's income tax law, distributions from GPR's retained earnings
  are taxable at a rate that

  varies depending upon the business activity that generated the earnings,
  generally 10%. For Puerto Rico income tax purposes, GPR's net income
  derived from agricultural operation is 90% exempt from income taxes for a
  period expiring on December 31, 1997. In addition, GPR has been granted,
  with certain conditions, an industrial tax exemption covering 90% of the
  net income derived from the undesignated service activities covered in the
  grant for a period expiring on December 31, 2007. Equipment used by GPR in
  the packing operation is also 90% exempt from property taxes for a period
  expiring on December 31, 2007.
 
  SCVRC is a "C" Corporation, but since formation has only incurred operating
  losses.
 
  Income taxes have been provided for in accordance with the provisions of
  Statement of Financial Accounting Standards No. 109, Accounting for Income
  Taxes, which was adopted effective December 23, 1992. The cumulative effect
  of this change in accounting for income taxes had no material impact on the
  Partnership's consolidated financial statements.
 
  Included in the combined financial statements of the Predecessor Company
  are several "S" Corporations. As an "S" Corporation, all federal taxable
  income and expenses, with certain exceptions, flow directly to the
  stockholders and are not taxed at the corporate level. Also included is GPR
  which is taxed as described above.
 
  The income tax provision of the Predecessor Company has been provided in
  accordance with Accounting Principles Board Opinion No. 11, Accounting for
  Income Taxes.
 
  Reclassifications--Certain amounts in prior years' financial statements
  have been reclassified to conform with the 1995 financial statements.

9. SUBSEQUENT EVENTS
 
  On October 13, 1995, the Partnership, the Partnership's general and limited
partners, and other related and unrelated parties entered into the Gargiulo,
L.P. Plan and Agreement of Reorganization (the "Plan of Reorganization"). The
Plan of Reorganization provides that the development/license agreement (see
Note 7) with a related party, who is also a signatory to the Plan of
Reorganization, will be amended conditioned upon TIA's parent company
consummating a transaction whereby TIA will exchange its ownership interest in
the Partnership, currently 49.9% and to be 100%, for an ownership interest in
a third party. The amendment to the development/license agreement would
eliminate the related party's obligation to carry out further development
activities and would eliminate the Partnership's obligation to make further
payments to the related party, thereby causing the licenses referred to
therein to be deemed to be fully paid up. Therefore, the prepaid
development/license fee included in the accompanying consolidated financial
statements may have become impaired.
 
  On October 18, 1995, the Partnership became a defendant in two pending
lawsuits which involve personal injury claims by the families of three migrant
labor workers who were killed and by seven migrant labor workers who were
injured in a vehicle accident. The company hiring and transporting such farm
workers was an independent contractor engaged to arrange for migrant farm
labor for a Partnership farm. The plaintiffs allege that the vehicle in
question was in violation of one or more federal and state safety regulations
governing farm labor vehicles. The Partnership's insurance carriers have been
contacted regarding these lawsuits, but it has not yet been determined whether
the Partnership's insurance will be sufficient to cover these claims, if any.
Accordingly, the outcome of this litigation and the amount of damages, if any,
that may ultimately be incurred cannot be determined and no provisions for any
liability has been made in the accompanying consolidated financial statements.
 
  On December 29, 1995, the Partnership entered into an asset purchase
agreement for the acquisition by the Partnership of substantially all of the
assets, subject to certain liabilities, of an unrelated producer, packer and
broker of tomatoes and, to a lesser extent, other vegetables for $10 million
in cash and a $10 million promissory note, plus an earn-out payment based upon
certain earnings of the combined operations of the Partnership in Southwest
Florida and those being purchased from the seller. The Partnership will also
acquire the seller's 1995-1996 crop and assume liabilities related thereto. At
the closing, the Partnership would also commit to lease certain farm land from
affiliates of the seller. The consummation of the acquisition is subject to
satisfactory completion of closing documents, obtaining required consents and
verification of representations and warranties.

                         INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors
Gargiulo P.R., Inc.
 
  We have audited the consolidated balance sheets of Gargiulo P.R., Inc.
(formerly known as NTGargiulo P.R., Inc and South Coast Fruit and Vegetable,
Inc.) (a wholly-owned subsidiary of Gargiulo L.P.) and its subsidiary
(collectively referred to as the "Company") as of June 30, 1995 and 1994, and
the related statements of operations and retained earnings, and cash flows for
the years then ended, (not presented separately herein). These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statements presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Gargiulo
P.R., Inc. and subsidiary as of June 30, 1995 and 1994, and the consolidated
results of their operations, and their cash flows for the years then ended in
conformity with generally accepted accounting principles.

1. BASIS OF PRESENTATION OF INTERIM FINANCIAL INFORMATION (UNAUDITED)
 
  The accompanying unaudited consolidated condensed financial statements as of
September 30, 1995 and for each of the three month periods ended September 30,
1995 and 1994, included in this Registration Statement, have been prepared by
the Partnership which is responsible for their integrity and objectivity.
 
  The accounting policies followed for interim financial reporting are set
forth in the Notes to the Partnership's audited consolidated financial

the Securities and Exchange Commission.
  To the best of management's knowledge and belief, the statements and related

  The financial statements for the three month periods ended September 30,
1995 and 1994 herein include, in the opinion of management, all adjustments

              REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
To the Owners of Collier Farms:
 
  We have audited the accompanying combined balance sheets of Collier Farms
(see Note 1) as of June 30, 1995, 1994 and 1993, and the related combined
statements of operations and owners' equity and cash flows for the years then
ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these combined
financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Collier Farms as of June
30, 1995, 1994 and 1993, and the results of their operations and their cash
flows for the years then ended in conformity with generally accepted
accounting principles.

                         JUNE 30, 1995, 1994 AND 1993
 
1. BASIS OF PRESENTATION AND SUMMARY OF OPERATIONS:
 
  The accompanying combined financial statements represent the financial
statements of the following affiliated business enterprises collectively known
as Collier Farms (the Company):
 
  Collier Farm Equipment Company (CFEC), a Florida corporation
  Collier Farms, Inc. (CFI), a Florida corporation
  Colliergro, a division of Colliergro, Ltd., a Florida limited partnership
  CollierPac-Tomato, a division of Collier Groves & Packing, Ltd., a Florida
  limited partnership
  CollierPac-Vegetable, a division of Collier Groves & Packing, Ltd., a
  Florida limited partnership
  LDEC, a division of Collier Tec, Inc., a Florida corporation
 
  The above entities are under common control and have been combined to
provide a more meaningful presentation of the financial position and results
of operations of these entities which operate as a single business unit. All
significant intercompany balances have been eliminated in combination.
 
  The Company is primarily in the business of growing, packing, marketing and
shipping fresh produce.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
 Cash Management
 
  The Company is part of a group of affiliated companies operating in various
industries. As part of the overall cash management system, excess cash is
distributed and cash deficiencies are funded on a daily basis and are recorded
as capital distributions and contributions, respectively. Accordingly, capital
distributions and contributions have been netted in the accompanying combined
statements of owners' equity.
 
 Property, Plant and Equipment
 
  Property, plant and equipment are recorded at cost. Depreciation expense is
provided using the straight line method over the estimated lives of the assets
which range from 5 to 25 years.
 
 Income Taxes
 
  The corporations included in the Company have elected to file under
Subchapter S of the U.S. Internal Revenue Code. Accordingly, the revenues and
expenses of all entities flow through to the owners for tax purposes. The tax
returns and the amount of distributable income or loss are subject to
examination by federal and state taxing authorities. If such examinations
result in changes to distributable income or loss, the tax liability of the
owners would be changed accordingly.
 
 Other Income
 
  The Company periodically enters into agreements to produce, market and sell
crops with another unrelated party for a growing season. The Company's
proportionate share of income from these agreements is included in other
income in the accompanying combined statements of operations.
 
  Also included in other income is income from equipment rentals and other
services provided to both related and unrelated parties, insurance proceeds
from storm damage and refunds received on damaged inventories.
 
 Revenue Recognition
 
  Revenues are recognized when the related products are shipped.

1. BASIS OF PRESENTATION OF INTERIM FINANCIAL INFORMATION (UNAUDITED) AND
SUMMARY OF OPERATIONS:
 
  The accompanying unaudited combined financial statements have been prepared
in accordance with generally accepted accounting principles applied on a
consistent basis during the interim periods. Those financial statements should
be read in conjunction with the Company's audited combined financial
statements appearing elsewhere herein for the fiscal years ended June 30,
1995, 1994 and 1993.
 
  In the opinion of management, the interim financial statements reflect all
adjustments necessary, consisting only of normal recurring adjustments, to
present fairly the Company's combined financial position at September 30,
1995, and 1994 and the combined results of operations and cash flows for the
three months ended September 30, 1995, and 1994. Results for the periods ended
September 30, 1995, and 1994 are not necessarily indicative of results to be
expected for the entire fiscal year.

statements of the following affiliated business enterprises collectively known

  The Company is primarily in the business of growing, packing, marketing and
shipping fresh produce.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
 Cash Management
 
  The Company is part of a group of affiliated companies operating in various
industries. As part of the overall cash management system, excess cash is
distributed and cash deficiencies are funded on a daily basis and are recorded
as capital distributions and contributions, respectively. Accordingly, capital
distributions and contributions have been netted in the accompanying combined
statements of owners' equity.
 
 Property, Plant and Equipment

provided using the straight line method over the estimated lives of the assets
which range from 5 to 25 years.
 
 Income Taxes
 
  The corporations included in Collier Farms have elected to file under
Subchapter S of the U.S. Internal Revenue Code. Accordingly, the revenues and
expenses of all entities flow through to the owners for tax purposes. The tax

distributable income or loss, the tax liability of the owners would be changed
accordingly.

crops with another unrelated party for a growing season. The Company's

  5.4 Procedure. In the event that, from and after the Closing Date, a third
Person asserts any claim against any Holding Company Indemnified Party or any
Monsanto Indemnified Party with respect to any matter to which the foregoing
indemnities apply, the party against whom the claim is asserted (the
"Indemnified Party") shall give prompt written notice to the indemnifying
party (the "Indemnifying Party"), and the Indemnifying Party shall have the
right, at its election, to take over the defense or settlement of such claim
at its own expense by giving prompt written notice to the Indemnified Party;
provided, however, that, if the Indemnifying Party does not give such notice
and does not proceed diligently to defend the claim within thirty (30) days
after receipt of such notice of the claim, the Indemnifying Party shall be
bound by any defense or settlement that the Indemnified Party may make as to
such claim and shall reimburse the Indemnified Party for any and all losses
and expenses resulting therefrom. The Indemnified Party and the Indemnifying
Party shall cooperate in defending any such third Person's claim, and the
Indemnifying Party, to the extent the Indemnifying Party elects to defend such
claim, shall have reasonable access to records, information and personnel in
the possession or control of any other party hereto which are applicable to
the subject matter of any claim or which are otherwise pertinent to the
defense of such claim and the Indemnified Party shall otherwise cooperate with
the Indemnifying Party in all respects in connection therewith. The
Indemnifying Party shall reimburse the Indemnified Party for all of the
Indemnified Party's reasonable out-of-pocket costs incurred in connection with
the activities set forth in the immediately preceding sentence and in
enforcing this indemnification. Each party hereto shall have an obligation to
retain all records until the period ending on December 31 of the tenth (10th)
full calendar year following the Closing Date unless such records relate to
actions, claims or proceedings known to such party to be pending at the time
such records are scheduled not to be retained or unless such records are
required to be maintained for longer periods of time under applicable laws,
rules or regulations or unless such records relate to Taxes, in which case
each party hereto shall have an obligation to retain such records for the term
of the applicable statute of limitations, as the same may be extended or
tolled. Notwithstanding the foregoing, the Indemnifying Party shall not settle
or compromise any such claim without the prior written consent of the
Indemnified Party, such consent not to be unreasonably withheld, unless, after
consultation between such parties, the terms of such settlement or
 
                                     A-10
<PAGE>
 
compromise release such Indemnified Party from any and all liability with
respect to such claim and do not in any manner adversely affect the future
operations or activities of such Indemnified Party.
 
  5.5 Adjustment of Liability. In calculating any amount of damages to be paid
by Monsanto, Holding Company or Calgene as set forth in this Article 5, the
amount of such damages shall be reduced by all insurance reimbursements
credited to or received by the other party, relating to such damages. In
connection therewith, promptly after the Closing Date, each party hereto shall
obtain a waiver of subrogation with respect to such reimbursements from its
insurer(s).
 
  5.6 Certain Limitations on Monsanto's Indemnification Agreement. The
indemnification obligations contained in Section 5.2 hereof (other than clause
(iv) thereof) shall not apply to Liabilities, Actions or Damages to the extent
such Liabilities, Actions or Damages relate to or arise from matters disclosed
to Calgene by Monsanto in the Monsanto Disclosure Memorandum or in other
disclosures, certificates or reports (including, without limitation, the
Internal Audit Report and the notes to the Partnership Financial Statements)
given to Calgene prior to the Closing. No claim for indemnification shall be
made under Section 5.2 hereof with respect to Liabilities, Actions or Damages
relating to any breach of Section 6.1 hereof, unless the aggregate of all such
Liabilities, Actions or Damages exceeds $2,500,000 and then only the amount of
such Liabilities, Actions or Damages in excess of the initial $2,500,000 shall
be payable to the Holding Company Indemnified Parties thereunder. No
Liabilities, Actions or Damages shall be subject to payment by Monsanto under
Section 5.2 hereof to the extent that the aggregate amount of such claimed
Liabilities, Actions or Damages exceeds $22,500,000; provided, however, that
Liabilities, Actions or Damages caused by fraud on the part of Monsanto shall
not be subject to the $22,500,000 limitation. For purposes of determining
whether claims for indemnification are within the amounts set forth above, all
claims for indemnification by the Holding Company Indemnified Parties shall be
net of any unpaid claims (including indemnification claims that are unpaid by
reason of the $2,500,000 threshold) for indemnification by the Monsanto
Indemnified Parties. Any amounts payable to a Holding Company Indemnified
Party under Section 5.2 hereof relating to a breach of Section 6.1 hereof may
be made, at Monsanto's election, either in cash (at any time) or by one of the
following methods in the order presented (i.e., Monsanto may use a method only
after fully exhausting all prior methods): first, by offset to any loans
(other than loans under the Gargiulo Credit Facility Agreement) owed by the
Holding Company Indemnified Parties to Monsanto, second, by transfer of
Holding Company Common Stock, and, third, by offset to any loans owed by the
Holding Company Indemnified Parties to Monsanto under the Gargiulo Credit
Facility Agreement. For purposes of the foregoing, Holding Company Common
Stock transferred in satisfaction of an indemnification obligation shall be
valued at the greater of (i) the value of such Holding Company Common Stock at
Closing (if trading on a "when issued" basis on such date and otherwise the
value on such date of the Calgene Common Stock that will be converted into
such Holding Company Common Stock) and (ii) the value of such Holding Company
Common Stock at the time of such transfer (in each case such value to be equal
to the last reported sale price on the Nasdaq National Market or such other
national securities exchange on which such stock may be traded).
 
  5.7 Certain Limitations on Holding Company's and Calgene's Indemnification
Agreement. The indemnification obligations contained in Section 5.3 hereof
shall not apply to Liabilities, Actions or Damages to the extent such
Liabilities, Actions or Damages relate to or arise from matters disclosed to
Monsanto by Calgene in the Calgene Disclosure Memorandum or in other
disclosures, certificates or reports (including, without limitation, the notes
to the Financial Statements) given to Monsanto prior to the Closing. No claim
for indemnification shall be made under Section 5.3 hereof with respect to
Liabilities, Actions or Damages relating to any breach of Section 6.2 hereof,
unless the aggregate of all such Liabilities, Actions or Damages exceeds
$2,500,000 and then only the amount of such Liabilities, Actions or Damages in
excess of the initial $2,500,000 shall be payable to the Monsanto Indemnified
Parties thereunder. For purposes of determining whether claims for
indemnification are in excess of the amount set forth above, all claims for
indemnification by the Monsanto Indemnified Parties shall be net of any unpaid
claims (including indemnification claims that are unpaid by reason of the
$2,500,000 threshold) for indemnification by the Holding Company Indemnified
Parties.

  5.8 Limitations on Liability of the Parties. Notwithstanding anything to the
contrary contained in this Agreement, neither Monsanto, Calgene nor Holding
Company shall have any liability for any breach or falsity of a representation
or warranty under this Agreement (under Sections 5.2 or 5.3 hereof or
otherwise) to the extent the breach or falsity of the representation or
warranty upon which such liability would be based is disclosed:
 
    (a) in the case of Monsanto, in the Monsanto Disclosure Memorandum
  (including the schedules thereto) and in the Exhibits hereto, in the
  Internal Audit Report, in the Partnership Financial Statements (including
  the notes thereto), or disclosed in a written notice furnished to Calgene
  prior to the Closing; provided, however, that any such breach or falsity of
  a representation or warranty so disclosed to Calgene after the execution
  and delivery of this Agreement and prior to the Closing shall not affect
  the right of Calgene to elect not to close the Transactions as a result of
  any failure to satisfy the conditions set forth in Section 8.1 hereof (it
  being understood and agreed that if, despite such right of Calgene to elect
  not to close by reason of the breach or falsity so disclosed, Calgene shall
  nevertheless elect to close, thereby waiving such misrepresentation or
  breach, then neither Calgene nor Holding Company shall thereafter have any
  claim against Monsanto by reason of, in connection with or arising from any
  such disclosed breach or falsity of a representation or warranty); and
 
    (b) in the case of Calgene and Holding Company, in the Calgene Disclosure
  Memorandum (including the schedules thereto), in the Exhibits hereto, in
  the Financial Statements (including the notes thereto) or disclosed in a
  written notice furnished to Monsanto prior to the Closing; provided,
  however, that any such breach or falsity of a representation or warranty so
  disclosed to Monsanto after the execution and delivery of this Agreement
  and prior to the Closing shall not affect the right of Monsanto to elect
  not to close the Transactions as a result of any failure to satisfy the
  conditions set forth in Section 8.2 hereof (it being understood and agreed
  that if, despite such right of Monsanto to elect not to close by reason of
  the breach or falsity so disclosed, Monsanto shall nevertheless elect to
  close, thereby waiving such misrepresentation or breach, then Monsanto
  shall thereafter have no claim against Calgene or Holding Company by reason
  of, in connection with or arising from any such disclosed breach or falsity
  of a representation or warranty).

                        Representations and Warranties
 
  6.1 Monsanto's Representations and Warranties. Monsanto represents and
warrants as follows:
 
    (a) Monsanto is a corporation duly organized, validly existing and in
  good standing under the laws of the State of Delaware. Tomato Associates is
  a corporation duly organized, validly existing and in good standing under
  the laws of the state of its incorporation and has all necessary corporate
  powers and authority to carry on its business as now conducted and to own,
  lease and operate its properties. Monsanto owns all of the issued and
  outstanding capital stock of Tomato Associates free and clear of all liens,
  claims, security interests or encumbrances and there are no outstanding
  options, warrants or other rights to acquire capital stock of Tomato
  Associates. As of the date hereof, Tomato Associates is duly licensed or
  qualified to do business and is in good standing in every jurisdiction in
  which the nature of its business or ownership of its properties requires
  such qualification except where the failure to qualify will not have a
  Material Adverse Effect. As of the date hereof, except for its ownership
  interest in Gargiulo (and indirect investments or other interests because
  of such interest in Gargiulo), Tomato Associates has no subsidiaries and
  has no direct or indirect beneficial investment or other interest in any
  other Person. Tomato Associates has delivered to Calgene complete and
  correct copies of its certificate of incorporation and by-laws as amended
  and in effect on the date hereof.
 
    (b) Monsanto has full corporate power and authority to execute and
  deliver the Transaction Agreements to which it is a party and to carry out
  the terms and obligations thereof. Monsanto has taken all corporate action
  necessary to authorize the execution, delivery and performance of this
  Agreement and to consummate the Transactions. This Agreement constitutes,
  and each of the Transaction Agreements after
 
                                     A-12
<PAGE>
 
  execution and delivery at the Closing shall on the Closing Date constitute,
  a valid and binding obligation of Monsanto, enforceable in accordance with
  their respective terms and conditions.
 
    (c) The execution, delivery and performance of the Transaction Agreements
  will not violate or constitute a default, or give rise to a violation or
  default under (i) any material contract, mortgage, indenture, promissory
  note or similar agreement to which Monsanto or Tomato Associates is a
  party, or by which either of them is bound, (ii) their respective charter
  or by-laws, or (iii) any court injunction or decree, or any valid and
  enforceable order of a governmental agency having jurisdiction over
  Monsanto or Tomato Associates.
 
    (d) Except as provided in Schedule 6.1(d) to the Monsanto Disclosure
  Memorandum, as of the date hereof, there are no actions, suits,
  investigations or proceedings pending or, to the best of Monsanto's
  knowledge and belief, threatened against Tomato Associates or against any
  asset, interest or right of Tomato Associates that might have a Material
  Adverse Effect. As of the date hereof, there are no actual or, to the best
  of Monsanto's knowledge and belief, threatened actions, suits or
  proceedings which present a claim to restrain or prohibit the Transactions.
 
    (e) As of the Closing Date, Tomato Associates will have all right, title
  and interest to the Assets, except any Assets which may be transferred to
  the Holding Company.
 
    (f) Shares of the stock of Holding Company to be received by Monsanto
  pursuant to the Exchange will be acquired for investment for its own
  account, not as a nominee or agent, and not with a view to the sale or
  distribution of any part thereof.
 
    (g) All material Tax Returns relating to, or including items attributable
  to the operations of, each of Tomato Associates and the Tomato Associates
  Subsidiaries or relating to any Tax for which Tomato Associates or any
  Tomato Associates Subsidiary may be liable that were required to be filed
  have been filed and all such Tax Returns were correct and complete in all
  material respects. All Taxes that are shown to be due on any such Tax
  Returns have been paid. All Taxes that Tomato Associates or any Tomato
  Associates Subsidiary is or was required by law to withhold or collect or
  any such Taxes for which Tomato Associates or any Tomato Associates
  Subsidiary may be liable have been duly withheld or collected and, to the
  extent required, have been paid to the proper governmental entity. Tomato
  Associates has made available to Calgene correct and complete copies of the
  relevant portions of all federal income Tax Returns (and related
  workpapers), examination reports and statements of deficiencies assessed
  against or agreed to since January 1, 1992, relating to any Tax of Tomato
  Associates or any Tomato Associates Subsidiary. Neither Tomato Associates
  nor any Tomato Associates Subsidiary has been a United States real property
  holding corporation within the meaning of Section 897(c)(2) of the Code
  during the applicable period specified in Section 897(c)(1)(A)(ii) of the
  Code. Neither Tomato Associates nor any Tomato Associates Subsidiary is a
  party to any Tax allocation or sharing agreement. Neither Tomato Associates
  nor any Tomato Associates Subsidiary is a "consenting corporation" within
  the meaning of Section 341(f) of the Code, and none of the assets of Tomato
  Associates or the Tomato Associates Subsidiaries are subject to an election
  under Section 341(f) of the Code. Adequate provision for any Tax due or to
  become due for each of Tomato Associates and the Tomato Associates
  Subsidiaries for the period or periods through and including June 30, 1995,
  has been made and is reflected on the June 30, 1995 financial statements of
  Tomato Associates and the Partnership Financial Statements. Deferred Taxes
  of Tomato Associates and the Tomato Associates Subsidiaries have been
  provided for in accordance with generally accepted accounting principles.
  Monsanto has no present plan or intention to dispose of any of the Holding
  Company Capital Stock received in the Exchange.
 
    (h) The copies of the certificate of incorporation of Tomato Associates,
  including all amendments thereto, certified by the Secretary of State of
  the State of Delaware, and the by-laws of Tomato Associates, certified by
  the Assistant Secretary of Tomato Associates, furnished to Calgene are

  by-laws as in effect on the date hereof. The minute books of Tomato
  Associates have been made available to Calgene and its representatives, and
  contain accurate records of all meetings of, and any corporate actions or
  written consents by, the shareholders and the Board of Directors of Tomato
  Associates and any committee thereof. The Tomato Associates Financial

  Statements have been delivered to Calgene. The Tomato Associates Financial
  Statements were prepared in accordance with generally accepted accounting
  principles consistently applied throughout the periods involved, and fairly
  present, in all material respects, the financial condition of Tomato
  Associates, as of the dates indicated and the results of its operations for
  the periods then ended in accordance with generally accepted accounting
  principles.
 
    (i) Tomato Associates is not in conflict with, or in default or violation
  of, (i) any law, rule, regulation, order, judgment or decree (including,
  without limitation, any of the foregoing relating to zoning or land use)
  applicable to Tomato Associates or by which any property or asset of Tomato
  Associates is bound or affected, or (ii) any note, bond, mortgage,
  indenture, contract, agreement, lease, license, permit, franchise or other
  instrument or obligation to which Tomato Associates is a party or by which
  any property or asset of Tomato Associates is bound or affected, except for
  any such conflicts, defaults or violations that would not, individually or
  in the aggregate, have a Material Adverse Effect.
 
    (j) When the Registration Statement shall be filed and when it shall
  become effective and when the Proxy Statement shall first be mailed to
  Calgene stockholders, and at all times subsequent to such mailing date up
  to and including the Closing Date, including, without limitation, the date
  of the meeting of Calgene's stockholders referred to in Section 9.3 hereof,
  to which the Proxy Statement relates, the information supplied by Monsanto
  to Holding Company in writing for inclusion in the Registration Statement
  or supplied by Monsanto to Calgene in writing for inclusion in the Proxy
  Statement and all supplements and amendments thereto, including information
  relating to the Partnership and the General Partner (such information being
  hereafter referred to as the "Monsanto Proxy Information") shall not
  contain any untrue statement of a material fact or omit to state a material
  fact required to be stated therein or necessary in order to make the
  statements therein, at the time and in light of the circumstances under
  which they are made, not misleading. If, at any time prior to the Closing
  Date, any event relating to Monsanto or any of its Affiliates, officers or
  directors shall be discovered by Monsanto which causes any Monsanto Proxy
  Information previously supplied by Monsanto to Holding Company or Calgene
  to contain any untrue statements of a material fact or to omit to state a
  material fact required to be stated therein or necessary in order to make
  the statements therein not misleading, Monsanto shall promptly inform
  Calgene and Holding Company.
 
    (k) With respect to the General Partner and the Partnership and except as
  disclosed in the Monsanto Disclosure Memorandum, in other written
  certificates, reports or disclosures (including, without limitation, the
  Internal Audit Report and the notes to the Partnership Financial
  Statements) given to Calgene prior to the Closing, or herein:

    suits, investigations or proceedings instituted, pending or, to the
    best of Monsanto's knowledge and belief, threatened against the General
    Partner or the Partnership or any asset, interest or right of the
    General Partner or the Partnership that might have a Material Adverse
    Effect.
 
      (iii) The Partnership Financial Statements have been delivered to
    Calgene. The Partnership Financial Statements were prepared in
    accordance with generally accepted accounting principles consistently
    applied throughout the periods involved, and fairly present, in all

  standing under the laws of the State of Delaware and has all necessary
  corporate power and authority to carry on its business as now conducted and

  incorporation and has all necessary corporate power and authority to carry
  on its business as now conducted and as proposed to be conducted and to

  6.2(a) to the Calgene Disclosure Memorandum, Calgene owns all of the issued
  and outstanding capital stock of each Calgene Subsidiary free and clear of
  all liens, claims, security interests or encumbrances. Calgene and each
  Calgene Subsidiary are duly licensed or qualified to do business and are in
  good standing in every jurisdiction in which the nature of their businesses
  or the ownership of their properties requires such qualification except
  where the failure to qualify will not have a Material Adverse Effect. As of
  the date hereof, each Calgene Subsidiary is set forth on Schedule 6.2(a)(i)
  to the Calgene Disclosure Memorandum. Except as set forth in Schedule
  6.2(a)(i) to the Calgene Disclosure Memorandum and except for cash
  equivalents and marketable securities held for investment purposes, as of
  the date hereof, Calgene has no subsidiaries and has no direct or indirect
  beneficial investment or other interest (including partnership interests)
  in any other Person. Calgene and each Calgene Subsidiary have delivered to
  Monsanto complete and correct copies of their respective certificates of
  incorporation and by-laws as amended and in effect on the date hereof.
 
    (b) It has full corporate power and authority to execute and deliver the
  Transaction Agreements to which it is a party and to carry out the terms
  and obligations thereof. Calgene has taken all corporate action necessary
  to authorize the execution, delivery and, subject only to the approval of
  the Calgene stockholders, performance of this Agreement and all related
  documents and instruments and, subject only to the approval of the Calgene
  stockholders, to consummate the Transactions. This Agreement constitutes,
  and each of the other Transaction Agreements to be executed by Calgene
  after execution and delivery at the Closing shall on the Closing Date
  constitute, its valid and binding obligation, enforceable in accordance
  with its respective terms and conditions.
 
    (c) Except as set forth in Schedule 6.2(c) to the Calgene Disclosure
  Memorandum, the execution, delivery and performance of the Transaction
  Agreements will not violate or constitute a default or give rise to a
  violation or default under (i) any material contract, mortgage, indenture,
  promissory note or similar agreement to which Calgene or any of the Calgene
  Subsidiaries is a party, or by which any of them is bound, (ii) their
  respective charter or by-laws, or (iii) any court injunction or decree, or
  any valid and enforceable order of a governmental agency having
  jurisdiction over Calgene or any of the Calgene Subsidiaries.
 
    (d) The authorized capital stock of Calgene consists of (i) 50,000,000
  shares of Calgene Common Stock and (ii) 5,000,000 shares of Calgene
  Preferred Stock. As of September 25, 1995, 30,250,408 shares of Calgene
  Common Stock were issued and outstanding, no shares were held in treasury

  Stock granted under the Calgene Plans and no warrants to purchase shares of
  Calgene Common Stock were issued and outstanding, as set forth by holder,

  are, and all such shares issued upon exercise of the options will, upon
  such issuance, be, duly authorized and validly issued and are, or will be,
  fully paid and nonassessable. The Calgene Preferred Stock issued and
  outstanding as of the Closing Date (but before giving effect to the
  Transactions) shall be duly authorized, validly issued, fully paid and
  nonassessable shares of Calgene Preferred Stock. Except as set forth in
  Schedule 6.2(d) to the Calgene Disclosure Memorandum, there are no options,
  warrants, rights, calls, subscriptions, stock appreciation rights,
  commitments, understandings or agreements of any character obligating
  Calgene or any of the Calgene Subsidiaries to issue any shares of capital
  stock or any security representing the right to purchase or otherwise
  receive any such shares, except for the outstanding options referred to
  above in this Section 6.2(d), and the rights of Monsanto and Holding
 
                                     A-17

  Company under this Agreement. Except for restrictions on transfer arising
  under the federal securities laws or as described in Schedule 6.2(d) to the
  Calgene Disclosure Memorandum, there are no existing restrictions on
  transfer, voting trusts, stockholder agreements or registration covenants
  known to Calgene relating to any outstanding shares of capital stock of
  Calgene or any Calgene Subsidiary. None of the outstanding shares of the
  Calgene Common Stock was issued in violation of the preemptive rights of
  any present or former stockholder and Calgene's stockholders are not
  entitled to preemptive rights. Since the Balance Sheet Date, there have
  been no Restricted Payments declared or paid in respect of the shares of
  any capital stock of Calgene or any Calgene Subsidiary.
 
    (e) When the Registration Statement shall be filed and when it shall
  become effective and when the Proxy Statement shall first be mailed to
  Calgene stockholders, and at all times subsequent to such mailing date up
  to and including the Closing Date, including, without limitation, the date
  of the meeting of Calgene's stockholders referred to in Section 9.3 hereof,
  to which the Proxy Statement relates, the Proxy Statement and the
  Registration Statement and all supplements and amendments thereto (i) shall
  comply in all material respects with the provisions of the Exchange Act and
  the Securities Act, and all applicable rules and regulations of the
  Commission thereunder, and (ii) shall not contain any untrue statement of a
  material fact or omit to state a material fact required to be stated
  therein or necessary in order to make the statements therein, at the time
  and in light of the circumstances under which they are made, not misleading
  (except that no representation is made as to information provided by
  Monsanto, the General Partner, the Partnership or any Affiliate thereof).
 
    (f) Except as disclosed in Calgene's Form 10-K for the years ended June
  30, 1994 and June 30, 1995 or in Calgene's September 30, 1994, December 31,
  1994, or March 31, 1995, Form 10-Q or in the Form 8-K filed by Calgene on

  of operations since June 30, 1994.
 
    (g) Except as set forth in Schedule 6.2(g) to the Calgene Disclosure
  Memorandum, as of the date hereof, there are no actions, suits or
  proceedings instituted, pending or, to the best of Calgene's knowledge and
  belief, threatened against Calgene or the Calgene Subsidiaries or against
  any asset, interest or right of Calgene or the Calgene Subsidiaries that
  might have a Material Adverse Effect. As of the date hereof, there are no
  actual or, to the best of Calgene's knowledge and belief, threatened
  actions, suits or proceedings which present a claim to restrain or prohibit
  the Transactions.
 
    (h) Except as provided for in the Transaction Agreements and the Amended

  complete copies of the following documents, including the exhibits and

      (v) Annual Report on Form 10-K for the fiscal year ended June 30,
    1995, as filed with the Commission, which contains the audited
    consolidated balance sheet of Calgene as of such year end, and audited

    "Audited Financial Statements" and, together with the Prior Years'
    Audited Financial Statements and the Unaudited Financial Statements,
    the "Financial Statements").
 
    Except for a Current Report filed on Form 8-K on June 29, 1995 and Annual
  Report on Form 10-K for the fiscal year ended June 30, 1995, Calgene has to
  date filed no other reports or registration statements with the Commission
  since May 1, 1995. Calgene has timely filed all reports and other documents
  required to be filed by it under the Exchange Act, the Securities Act, and
  any applicable state securities or corporation statutes and regulations.
  The documents provided pursuant to this Section 6.2(i) included (or
  incorporated by reference) all required exhibits and did not contain at the
  time of filing thereof any untrue statement of a material fact or omit to
  state a material fact required to be stated therein or necessary to make
  the statements therein, in light of the circumstances under which they were

  with generally accepted accounting principles consistently applied
  throughout the periods involved, and fairly present, in all material
  respects, the financial condition of Calgene, as of the dates indicated and
  the results of its operations for the periods then ended in accordance with
  generally accepted accounting principles.
 
    (j) The copies of the certificates of incorporation of Calgene and the
  Calgene Subsidiaries, including all amendments thereto, certified by the
  Secretary of State of the State of Delaware, and the by-laws of Calgene and
  the Calgene Subsidiaries, certified by the applicable Secretary of Calgene

  complete copies of such certificates of incorporation and by-laws as
  currently in effect. The minute books of Calgene and the Calgene
  Subsidiaries have been made available to Monsanto and its representatives,
  and contain accurate records of all meetings of, and any corporate actions
  or written consents by, the shareholders and the Boards of Directors of
  Calgene and the Calgene Subsidiaries and any committee thereof.
 
    (k) Except as disclosed in the Audited Financial Statements or in
  Calgene's June 30, 1995, Form 10-K, or as set forth in Schedule 6.2(k) to
  the Calgene Disclosure Memorandum, there are no material agreements,
  contracts or commitments, written or oral, to which Calgene or any Calgene
  Subsidiary is a party or by which it or any of their property is bound as
  of the date hereof which are required to be disclosed in or attached as an
  exhibit to a Form 10-K or a Form 10-Q. All contracts between Calgene and
  its executive officers and between each Calgene Subsidiary and their
  respective executive officers shall be deemed to be material agreements or
  contracts.
 
    (l) With respect to any Person employed by Calgene or any Calgene
  Subsidiary on or after May 1, 1987, and who actually commenced such
  employment on or after November 6, 1986, (a) to the best of Calgene's
  knowledge, Calgene and/or such Calgene Subsidiary hired such Person in
  substantial compliance with IRCA and (b) Calgene and each Calgene
  Subsidiary have complied in all material respects with all recordkeeping
  and other requirements under IRCA.
 
    (m) Calgene and the Calgene Subsidiaries have filed or will file all Tax
  Returns required to be filed by them and have paid (or have accrued or will
  accrue, prior to the Closing Date) amounts for the payment of all Taxes due
  in respect of those Tax Returns. As of June 30, 1994, Calgene's and the
  Calgene Subsidiaries' federal and state income Tax carryforwards
  (including, without limitation, net operating loss carryforwards, foreign
  Tax credit carryforwards, minimum Tax credit carryforwards), are set forth
  on Schedule 6.2(m) to the Calgene Disclosure Memorandum; provided, however,
  that such Tax carryforwards are subject to limitation under Section 382 of
  the Code. Adequate provision for any Tax due or to become due for each of
  Calgene and the Calgene Subsidiaries for the period or periods through and
  including June 30, 1995 has been made and is reflected on the Financial
  Statements. Deferred Taxes of Calgene and the Calgene Subsidiaries have
  been provided for in accordance with generally accepted accounting
  principles, consistently applied.
 
                                     A-19
<PAGE>
 
    (n) None of Calgene or any Calgene Subsidiary is in conflict with, or in
  default or violation of, (i) any law, rule, regulation, order, judgment or
  decree (including, without limitation, any of the foregoing relating to
  zoning or land use) applicable to Calgene or any Calgene Subsidiary or by
  which any property or asset of Calgene or any Calgene Subsidiary is bound
  or affected, or (ii) any note, bond, mortgage, indenture, contract,
  agreement, lease, license, permit, franchise or other instrument or
  obligation to which Calgene or any Calgene Subsidiary is a party or by
  which any property or asset of Calgene or any Calgene Subsidiary is bound
  or affected, except for any such conflicts, defaults or violations that
  would not, individually or in the aggregate, have a Material Adverse
  Effect.
 
    (o) Schedule 6.2(o) to the Calgene Disclosure Memorandum contains a true
  and correct list of all employee benefit plans (as defined in Section 3(3)
  of the Employee Retirement Income Security Act of 1974, as amended
  ("ERISA")), and all bonus, stock option, stock purchase, restricted stock,
  incentive, deferred compensation, retiree medical or life insurance,
  supplemental retirement, severance or other benefit plans, programs or
  arrangements, and all employment, severance or compensation agreements
  maintained, or contributed to, by Calgene or any Calgene Subsidiary or with
  respect to which any such entity is a party or has incurred any current
  obligation, or could incur any obligation under Section 4069 or Section
  4212(c) of ERISA (collectively, the "Calgene Plans"). Except as disclosed
  on Schedule 6.2(o) to the Calgene Disclosure Memorandum, each Calgene Plan
  is in writing and Calgene has furnished Monsanto with a complete and
  accurate copy of each Calgene Plan document and, as applicable, (i) each
  trust or other funding arrangement, (ii) each summary plan description and
  summary of material modifications, (iii) the most recently filed Internal
  Revenue Service ("IRS") Form 5500 and (iv) the most recently received IRS
  determination letter for each such Calgene Plan.
 
    (p) None of the Calgene Plans is subject to Title IV of ERISA. Neither
  Calgene nor any Calgene Subsidiary has incurred any material liability nor
  reasonably expects to incur any material liability under, arising out of or
  by operation of Title IV of ERISA. Except as set forth in Schedule 6.2(p)
  to the Calgene Disclosure Memorandum, no Calgene Plan provides for the
  payment of compensation or benefits which would be contingent upon a
  "change in control", within the meaning of such term under Section 280G of
  the Code.
 
    (q) Each Calgene Plan is being operated in all material respects in
  accordance with its terms and the requirements of applicable law. No legal
  action, suit or claim is pending or threatened with respect to any Calgene
  Plan (other than claims for benefits in the ordinary course) and no fact or
  event exists that could give rise to any such action, suit or claim, in
  each case, where such action, suit or claim could result in any material
  liability. Each Calgene Plan that is intended to be qualified under Section
  401(a) of the Code or Section 401(k) of the Code has received a favorable
  determination letter from the IRS that it is so qualified and no fact or
  event has occurred since the date of such determination letter from the IRS
  to adversely affect the qualified status of any such Calgene Plan.
 
    (r) The list of outstanding stock options granted to any current or
  former employee or independent contractor that is set forth in Schedule
  6.2(r) to the Calgene Disclosure Memorandum is a list of all outstanding
  options and related exercise prices with respect to shares of Calgene
  Common Stock granted to such persons on or prior to the date indicated
  therein.
 
    (s) Neither the IRS nor any other taxing authority or agency, domestic or
  foreign, is now asserting or, to the best knowledge of Calgene, threatening
  to assert against Calgene or any Calgene Subsidiary any deficiency or claim
  for additional Taxes or interest thereon or penalties in connection
  therewith. None of Calgene or any Calgene Subsidiary has granted any waiver
  of any statute of limitations with respect to, or any extension of a period
  for the assessment of, any federal, state, county, municipal or foreign
  income Tax. Neither Calgene nor any Calgene Subsidiary has made an election
  under Section 341(f) of the Code.
 
  6.3 Survival of Representations and Warranties. No party (the "Warranting
Party") shall have any obligation or liability to another party (the
"Benefitted Party") on account of the breach by the Warranting Party of any
representation or warranty set forth in this Article 6 unless the Benefitted
Party shall have notified the Warranting Party of such breach within two (2)
years after the Closing Date. Notwithstanding the foregoing,
 
                                     A-20
<PAGE>
 
(a) the representations and warranties set forth in Sections 6.2(c), 6.2(d)
and 6.2(e) hereof, to the extent applicable to the shares of Holding Company
Capital stock to be issued in the Merger and the Exchange, shall survive the
Closing indefinitely; (b) for purposes of the Credit Facility Agreements, the
representations and warranties of Calgene set forth in Section 6.2 hereof
shall survive until the later of (i) the termination of both of the commitment
periods set forth in the Credit Facility Agreements and (ii) the date that all
outstanding principal and accrued interest under such Credit Facility
Agreements has been repaid in full or converted into Holding Company Common
Stock; and (c) the representations and warranties provided in Sections 6.1(g)
and 6.2(m) hereof shall survive the Closing indefinitely.
 
                                   ARTICLE 7
 
                                   Employees
 
  7.1 Offers of Employment. Calgene or Holding Company ("Employer") shall
offer employment to all of the Monsanto employees whose names are listed on
Schedule 7.1 to the Monsanto Disclosure Memorandum (hereinafter referred to as
"Employees"), in each case with salaries or wages which are not less than
their current salaries or wages with Monsanto and with comparable working
conditions to those enjoyed by similarly situated Employer employees. Employer
and Monsanto shall cooperate to effect orderly presentations and discussions
with the Employees of the various aspects of their prospective employment with
Employer and their disengagement from employment with Monsanto. Those
Employees who accept employment with Employer shall hereinafter be referred to
as "Employees Hired by the Purchaser" or "EHBPs."
 
  7.2 Employee Benefits. Employer shall provide the EHBPs with all of the
compensation, incentive compensation, retirement and employee benefit plans,
programs and arrangements generally available to the other similarly situated
employees of Employer ("Employer's Benefit Plans"), and the EHBPs shall be
eligible to participate in Employer's Benefit Plans on the same basis and
under the same terms as the other similarly situated employees of Employer.
 
  From and after the Closing Date, Employer shall grant to all EHBPs credit
under the Employer's Benefit Plans for all service with Monsanto, and any
Monsanto Affiliate, for all purposes for which said service was recognized by
Monsanto, including without limitation, disability, vacation, severance plans
or policies, eligibility for participation and vesting in Employer's Section
401(k) plans, and any seniority-based plan, practice or policy. To the extent
that any medical plan maintained by Employer contains restrictions or
limitations on pre-existing medical conditions, Employer shall waive those
restrictions. Employer shall recognize all covered medical expenses incurred
by EHBPs and their eligible dependents during calendar year 1995 prior to the
Closing Date for purposes of satisfying the existing calendar year deductibles
and co-payment limitations, if any, under its medical plans.
 
  On the Closing Date, Monsanto shall take such action as may be necessary to
provide each EHBP with the right to effect (to the extent permitted by law) a
tax-free rollover of the EHBP's account balance in the Monsanto defined
contribution plan into Employer's Section 401(k) plan (or other individual
account plan maintained by Employer) or into an individual retirement account.
 
  If any EHBP is involuntarily terminated by Employer for reasons not
involving cause within 12 months of Closing, Employer shall pay the EHBP in a
single sum as soon as practicable after the EHBP's involuntary termination a
severance benefit equal in amount to the greater of: 2 weeks' base pay per
year of service or 4 months' base pay. The aforementioned severance payment
shall be in lieu of and supersede Employer's obligation to pay additional
severance under its regular severance plan.
 
  7.3 Confidentiality. Nothing contained in this Agreement shall constitute a
waiver or modification of, or an amendment to, the obligations of the EHBPs
respecting confidential information of Monsanto or third parties under
employment or confidentiality agreements, or otherwise as provided by law, it
being agreed that said
 
                                     A-21
<PAGE>
 
obligations and all other terms of such agreements shall continue in
accordance with the terms of such agreements or as otherwise provided by law.
The EHBPs may disclose confidential Monsanto information to Employer but only
to the extent that such information specifically relates to the operations of
Employer and the Business required by each such EHBP to perform his or her
duties and provided that the EHBP has entered into a confidentiality agreement
with Employer. Such information shall remain confidential information of
Monsanto and shall be maintained as confidential in accordance with Section
9.2 hereof.
 
  7.4 No Third Party Beneficiary Status. Nothing contained in this Article 7,
either express or implied, is intended or shall be construed to confer upon
any Person other than Monsanto, Calgene or Holding Company any rights or
remedies hereunder.

                             Conditions Precedent
 
  8.1 Conditions Precedent to Calgene's Obligations. All obligations of
Calgene under this Agreement are subject to the fulfillment, on or prior to
the Closing Date, of each of the following conditions or their waiver by
Calgene:
 
    (a) All representations and warranties of Monsanto contained in this
  Agreement shall be true in all material respects at and as of the Closing
  Date as though such representations and warranties had been made or given
  on such date (except to the extent such representations and warranties
  speak as of an earlier date), except (i) for changes contemplated by this
  Agreement and (ii) where the failure to be true and correct does not have a
  Material Adverse Effect on Monsanto or a Material Adverse Effect on the

  and warranties speak as of an earlier date), except (i) for changes
  contemplated by this Agreement and (ii) where the failure to be true and
  correct does not have a Material Adverse Effect on Calgene and the Calgene

  Brewery Co., Ltd. ("Kirin-Japan"), Kirin Agribio USA, Inc. ("Kirin USA")
  and the Plant Genetics-Kirin Partnership (the "PG-K Partnership") deemed
  adequate by Monsanto that Monsanto's potato assets would be unaffected by
  Calgene's ownership (through Calgene Subsidiaries) of an interest in the
  PG-K Partnership even if Monsanto subsequently acquired any or all of the
  outstanding securities of Holding Company, or (B) furnished evidence deemed
  adequate by Monsanto that either Kirin-Japan or Kirin USA would buy out
  Calgene's interest (owned by Calgene Subsidiaries) in the PG-K Partnership,
  on terms reasonably acceptable to Monsanto, such that Monsanto's potato
  assets would be unaffected by Calgene's past ownership (through Calgene
  Subsidiaries) of an interest in the PG-K Partnership even if Monsanto
  subsequently acquired any or all of the outstanding securities of Holding
  Company, and (ii) provided written assurances satisfactory to Monsanto that

  that the Transactions, including the Merger and the Exchange, will
  constitute transfers to a corporation controlled by Monsanto and the
  stockholders of Calgene within the meaning of Section 351(a) of the Code
  and that such transfers will not give rise to income, gain or loss to
  Monsanto or Holding Company. In connection with such opinion, Monsanto
  shall have received from Calgene a certificate, dated as of the Closing
  Date and signed by its chief executive officer and chief financial officer,
  to the effect that, to the best knowledge and belief of such officers, the
  statement of facts and representations made on behalf of Calgene's
  management, presented to such counsel delivering such opinion, were at the
  date of such presentation, true, correct and complete and are on the date
  of such certificate, to the extent contemplated by the presentation, true,

representatives of Monsanto, reasonably approved by Calgene, shall have full
access, during reasonable Calgene business hours, to all the assets,

  9.2 Confidentiality. Between the date of this Agreement and the Closing Date
and for a period of ten (10) years after the Closing Date (or, if this
Agreement is terminated prior to Closing, for a period of ten (10) years after
the date hereof), each party hereto shall treat, and shall cause its
respective directors, officers, employees, agents, representatives,
consultants and financial institutions to treat, as the other party's
confidential property and not use or disclose to others or permit its
directors, officers, employees, agents, representatives, consultants and
financial institutions to use or disclose to others, without the prior written
consent of such other party, any non-publicly available information or data of
such other party (including, but not limited to, any technical information or
data provided by such other party) which may have heretofore or hereafter been
provided or disclosed by such other party in connection with this Agreement,
any negotiations pertaining thereto or any of the Transactions. This Section
9.2 shall not prevent any party hereto from using or disclosing to others
information: which such party can show has become part of the public domain
other than by acts or omissions of such party, its directors, officers,
employees, agents, representatives, consultants and financial institutions;
which has been furnished to such party by third parties as a matter of right,
without restriction on disclosure or use known to such party; which was
lawfully in such party's possession prior to the time Monsanto and Calgene
first entered into discussions related to the subject matter of this Agreement
and which was not acquired by such party, its directors, officers, employees,
agents, representatives, consultants and financial institutions directly or
indirectly from the other party, its directors, officers, employees, agents,
consultants and financial institutions; which a party can prove was developed
by it independent of any information received from such other party, its
directors, officers, employees, agents, representatives, consultants and
financial institutions, either directly or indirectly; or which such party is
required to disclose by applicable law or regulation, in which case the party
so required to disclose shall give the other party prompt notice of such
requirement in all cases with sufficient time for such other party to seek a
protective order or other limit on disclosure (unless the party subject to the
disclosure requirement would suffer penalties or sanctions for failure to
immediately disclose such information). It is further understood and agreed
that specific information shall not be deemed available to the public or in
any party's prior possession merely because it is embraced by more general
information available to the public or in such party's prior possession. In
the event that this Agreement or the Transactions are not consummated, any and
all notes, memoranda, records, drawings, tracings, specifications, sketches,
reports or other documents, including, without implied limitation, all copies,
excerpts or reproductions thereof, furnished or made available by Monsanto to
Calgene, or Calgene to Monsanto as the case may be, their respective
directors, officers, employees, agents, representatives, consultants and
financial institutions or developed thereby shall be promptly destroyed by
such party at such other party's request and such party shall advise such
other party in writing that such destruction has been completed. This Section
9.2 shall survive any termination of this Agreement.
 
  9.3 Registration Statement. Calgene shall cause Holding Company to file the
Registration Statement with the Commission, and Calgene shall use its
reasonable best efforts to cause the Registration Statement to become
effective under the Securities Act and to cause Holding Company to take any
action required to be taken under the applicable state Blue Sky or securities
laws in connection with the issuance of the shares of Holding Company Common
Stock upon consummation of the Merger. Monsanto shall furnish, or cause to be
furnished, such information concerning Gargiulo and Tomato Associates and
itself as Calgene may reasonably request in connection with such action. As
promptly as practicable following the execution and delivery of this
Agreement, unless this Agreement shall have been previously terminated in
accordance with Article 11 hereof, Calgene shall submit the Merger to its
stockholders for approval and adoption at a meeting of its stockholders called
by Calgene for such purpose. Unless this Agreement shall have been previously
terminated in accordance with Article 11 hereof, Calgene's Board of Directors
shall recommend that Calgene's stockholders vote to approve and adopt the
Merger and the other matters to be submitted to Calgene's stockholders in
connection therewith and shall use its best efforts to solicit and secure from
its stockholders their approval and adoption of the Merger (unless, in either
case, in the discharge of its fiduciary duties, after receiving advice of
counsel, Calgene's Board
 
                                     A-25
<PAGE>
 
of Directors shall determine not to make, or to change, such recommendation or
not so to solicit and secure such stockholders' approval). In connection with
the stockholders meeting, Calgene shall prepare and file with the Commission,
as soon as reasonably practicable, a proxy statement of Calgene with respect
to this Agreement and the Transactions and use all reasonable efforts to have
such proxy statement cleared by the Commission under the Exchange Act. The
Calgene proxy statement, in the form first sent to Calgene stockholders, is
herein called the "Proxy Statement".

  10.1 Time and Place of Closing. The Closing shall take place at 11:00 A.M.
(local time) on the date that the Effective Time occurs (or the immediately
preceding day if the Effective Time is earlier than 11:00 A.M.), or at such
other time as the parties may mutually agree. The place of Closing shall be at
such place as may be mutually agreed upon by the parties.
 
  10.2 Effective Time. The Transactions, including the transfer of Assets and
the exchange of shares contemplated by Article 2 hereof and the Merger
contemplated by Article 3 hereof, and the Plan of Merger shall become
effective on the date the Secretary of State of the State of Delaware accepts
for filing a Certificate of Merger reflecting the Merger. Unless otherwise
mutually agreed upon in writing by Calgene and Monsanto, the parties shall
cause the Effective Time to occur on the first business day following the last
to occur of (i) the effective date (including expiration of any applicable
waiting period) of the order of any other federal or state regulatory agency
approving the Transactions, if such approval is required, or the expiration of
any required waiting period after the filing of any required notice to any
federal or state regulatory agency required for consummation of the

  11.1. Termination. Notwithstanding anything herein or elsewhere to the
contrary, this Agreement may be terminated and the Transactions (including,
without limitation, the Merger) abandoned at any time prior to the Closing
Date, whether before or after approval by the stockholders of Calgene:
 
    (a) by mutual consent of the Monsanto Board of Directors and the Calgene
  Board of Directors;
 
    (b) by either the Monsanto Board of Directors or the Calgene Board of
  Directors, if the Transactions shall not have been consummated on or before
  March 31, 1996, unless such failure so to consummate shall be due to the
  failure of the party seeking to terminate this Agreement to perform in all
  material respects each of its obligations under this Agreement required to
  be performed by it on or prior to the Closing Date pursuant to the terms
  hereof;
 
    (c) by the Monsanto Board of Directors or the Calgene Board of Directors,
  if the Calgene Board of Directors shall withdraw or change its respective
  recommendation to its stockholders to adopt and approve this Agreement and
  the Merger or authorize the Transactions, as the case may be, or if the
  Calgene stockholders fail to adopt and approve this Agreement or the
  Merger;
 
    (d) by the Monsanto Board of Directors, if Calgene shall breach its
  obligations set forth in Section 9.9(a) hereof;
 
                                     A-30
<PAGE>
 
    (e) by the Monsanto Board of Directors, if events shall occur that render
  impossible the satisfaction of one or more of the conditions set forth in
  Section 8.2 hereof and shall not be waived (or deemed waived) by Monsanto;
  and
 
    (f) by the Calgene Board of Directors, if events shall occur that render
  impossible the satisfaction of one or more of the conditions set forth in

and abandonment of this Agreement and the Transactions (including the Merger),

and their respective directors, officers, employees and stockholders shall
have no obligation or liability to each other hereunder, except as provided in
Sections 9.2, 11.3 and 12.12 hereof and except that nothing herein shall
relieve any party from liability for any willful breach of this Agreement.
 
  11.3 Calgene Termination Payment. If this Agreement is terminated or the
Transactions abandoned for any of the following reasons:
 
    (a) the Calgene Board of Directors shall withdraw, change in a manner
  adverse to Monsanto or fail to make its recommendations to stockholders to
  approve the Merger; or
 
    (b) Calgene shall breach its obligations set forth in Section 9.9(a)
  hereof,
 
and a Calgene Acquisition Transaction is consummated within 12 months after
the date of termination or abandonment of this Agreement, then Calgene shall
promptly (and in any event within 10 days of receipt of a written notice from
Monsanto) pay to Monsanto a fee in cash equal to $7,500,000.

or acceptance of documents containing terms or conditions at variance with or
in addition to those set forth in this Agreement and the other Transaction

to constitute a continuing waiver of any other breach or default or of any
other right or remedy, unless such waiver be expressed in writing signed by
the party to be bound. Failure of a party to exercise any right shall not be
deemed a waiver of such right or rights in the future.

  2.2 Requested Registration.
 
  (a) Request for Registration. Holders of Registrable Securities shall have
the right to request (with such requests in writing and stating the number of
shares of Registrable Securities to be disposed of and the intended method of
disposition of shares by such Holders) up to two (2) registrations on Form S-3
(and up to two (2) additional registrations on Form S-3 for each conversion of
outstanding principal or interest into shares of Common Stock upon the
occurrence of an "Event of Default" under the Company Credit Facility or the
Gargiulo Credit Facility (as defined in each such Credit Facility,
respectively)) at the Company's expense and an unlimited number of additional
registrations on Form S-3 at the selling Holder's expense, provided that the
requests for additional registrations are made by Holders of at least ten
percent (10%) of the Registrable Securities, subject only to the following:
 
    (i) The Company shall not be required to effect a registration pursuant
  to this Section 2.2 prior to September 30, 1998, unless an Event of Default
  has occurred and is continuing under the Company Credit Facility or under
  the Gargiulo Credit Facility, in which event the Company shall be required
  to effect a registration pursuant to this Section 2.2 at any time upon the
  request of a Holder with respect to any shares of Common Stock issued to a
  Holder upon conversion of outstanding principal or accrued interest under
  either the Company Credit Facility or the Gargiulo Credit Facility after
  the occurrence of an Event of Default under either of such agreements.
 
    (ii) The Company shall not be required to effect a registration pursuant
  to this Section 2.2 within one hundred eighty (180) days after the
  effective date of the last such registration pursuant to this Section 2.2.
 
    (iii) The Company shall not be required to effect a Registration
  Statement in any particular jurisdiction in which the Company would be
  required to execute a general consent to service of process in effecting
  such registration, qualification or compliance, unless the Company is
  already subject to service in such jurisdiction and except as may be
  required by the Securities Act or applicable rules or regulations
  thereunder.
 
    (iv) The Company shall not be required to effect a Registration Statement
  for a period of not more than ninety (90) days immediately following the
  delivery of a certificate signed by the President of the Company to the
  Requesting Holders stating that, in the good-faith judgment of the Board of
  Directors of the Company, it would be seriously detrimental to the Company
  and its shareholders for such Registration Statement to be filed on or
  before the date filing would otherwise be required hereunder; provided,
  however, that the Company may not utilize this right more than once in any
  twelve (12) month period and the Company may not exercise this right based
  on the fact that the Company has recently registered any of its securities
  for the account of a security holder or holders exercising their respective
  demand registration rights.
 
  If the Company cannot qualify for registration on Form S-3, then the Company
shall effect any registration required or requested by the Holder on Form S-1,
or such other appropriate form, in which event this Section 2.2 shall apply in
all respects as if the words "Form S-3" were replaced by the words "Form S-1"
or the appropriate designation for such other form.
 
  (b) Notice of Inclusion. The Company shall give written notice to all
Holders of Registrable Securities of the receipt of a request for registration
pursuant to this Section 2.2 and shall provide a reasonable opportunity for
other Holders to participate in the registration; provided, however, that, if
the registration is for an underwritten offering, then the terms of Section
2.2(c) hereof shall apply to all participants in such offering. Subject to the
foregoing, the Company shall use its best efforts to effect promptly the
registration of all shares of Registrable Securities on Form S-3 to the extent
requested by the Holder or Holders thereof for purposes of disposition.
 
  (c) Underwriting. If the Requesting Holders intend to distribute the
Registrable Securities covered by their request by means of an underwriting,
then they shall so advise the Company as a part of their request made pursuant
to this Section 2.2, and the Company shall include such information in the
written notice referred to in Section 2.2(b) hereof. The right of any Holder
to registration pursuant to this Section 2.2 shall be conditioned
 
                                      B-5
<PAGE>
 
upon such Holder's participation in such underwriting and the inclusion of
such Holder's Registrable Securities in the underwriting to the extent
requested and to the extent provided herein.
 
  The Company shall (together with all Holders proposing to distribute their
securities through such underwriting) enter into an underwriting agreement in
customary form with the representative of the underwriter or underwriters of
recognized national standing, selected for such underwriting by a majority in
interest of the Requesting Holders and reasonably acceptable to the Company.
Notwithstanding any other provision of this Section 2.2, if the representative
advises the Requesting Holders in writing that marketing factors require a
limitation on the number of shares to be underwritten, then the Requesting
Holders shall so advise all Holders, and the number of shares of Registrable
Securities that may be included in the registration and underwriting shall be
allocated first among all Holders thereof in proportion, as nearly as
practicable, to the respective amounts of Registrable Securities held by such
Holders at the time of filing the Registration Statement. No Registrable
Securities excluded from the underwriting by reason of the underwriter's
marketing limitation shall be included in such registration.
 
  If any Holder of Registrable Securities disapproves of the terms of the
underwriting, then such person may elect to withdraw therefrom by written
notice to the Company, the underwriter and the Requesting Holders. The
Registrable Securities and/or other securities so withdrawn shall also be
withdrawn from registration; provided, however, that, if, by the withdrawal of
such Registrable Securities, a greater number of Registrable Securities held
by other Holders may be included in such registration (up to the maximum of
any limitation imposed by the underwriters), then the Company shall offer to
all Holders who have included Registrable Securities in the registration the
right to include additional Registrable Securities in the same proportion used
to determine the underwriter limitation in this Section 2.2(c).
 
  If the underwriter has not limited the number of Registrable Securities to
be underwritten, then the Company and its executive officers, and such other
Persons as are determined by the Board of Directors, their successors, and
their assigns ("Other Selling Stockholders"), may include securities for their
own account in such registration if the underwriter so agrees and if the
number of Registrable Securities held by the Holders that would otherwise have
been included in such registration and underwriting will not thereby be
limited for any reason, including but not limited to the price for which the
Registrable Securities will be sold. To the extent that the underwriter wishes
to limit the number of shares to be included in the registration on behalf of
the Company and the Other Selling Stockholders, the shares of Common Stock to
be registered held by the Other Selling Stockholders shall be excluded from
such offering prior to excluding any shares held by the Company and those held
by the Company shall be excluded prior to excluding any Registrable Securities
held by the Holders.
 
  2.3 Company Registration.
 
  (a) Notice and Inclusion. If, at any time after September 30, 1998, the
Company shall determine to register any of its securities for its own account,
other than a registration relating solely to employee benefit plans, or a
registration relating solely to a Commission Rule 145 transaction, the Company
shall:
 
    (i) promptly give to each Holder written notice thereof (which shall
  include a list of the jurisdictions in which the Company intends to attempt
  to qualify such securities under the applicable blue sky or other state
  securities laws); and
 
    (ii) include in such registration (and any related qualification under
  blue sky laws or other compliance), and in any underwriting involved
  therein, all Registrable Securities specified in a written request or
  requests, within twenty (20) days after receipt of the written notice from
  the Company, by any Holder or Holders.
 
  (b) Underwriting. If the registration of which the Company gives notice is
for a registered public offering by the Company of its securities through an
underwriting, then the Company shall so advise the Holders as a part of the
written notice given pursuant to Section 2.3(a)(i) hereof. In such event, the
right of any Holder to registration pursuant to this Section 2.3 shall be
conditioned upon such Holder's participation in such underwriting and the
inclusion of such Holder's Registrable Securities in the underwriting to the
extent provided
 
                                      B-6
<PAGE>
 
herein. All Holders proposing to distribute their securities through such
underwriting shall (together with the Company, and all the Other Selling
Stockholders distributing their securities through such underwriting) enter
into an underwriting agreement in customary form with the underwriter or
underwriters selected for underwriting by the Company. Notwithstanding any
other provision of this Section 2.3, if the underwriter determines that
marketing factors require a limitation on the number of shares to be
underwritten, then the underwriter may exclude from such registration and
underwriting some or all of the Registrable Securities held by the Holders or
the stock held by Other Selling Stockholders in accordance with this Section
2.3(b). The Company shall so advise all Holders and all Other Selling
Stockholders distributing their securities through such underwriting, and (i)
as to the first registration in which Holders are entitled to participate
pursuant to this Section 2.3, the number of Registrable Securities and other
securities that may be included in the registration and underwriting shall be
allocated among all Holders thereof on the basis that shares held by all the
Other Selling Stockholders who are not Holders shall first be excluded to the
extent required and, if further exclusion is necessary, shares held by the
selling Holders shall then be excluded; provided, however, that, as among the
respective Other Selling Stockholders as a group on the one hand and the
Holders as a group on the other hand suffering such exclusion, the exclusion
shall be in proportion, as nearly as practicable, to the amount of securities
entitled to inclusion in such registration held by each of the Other Selling
Stockholders as a group and each of the Holders at the time of filing the
Registration Statement; and (ii) as to all subsequent registrations, the
number of shares of Registrable Securities and other securities that may be
included in the registration and underwriting shall be allocated among all
Other Selling Stockholders and the Holders in proportion, as nearly as
practicable, to the respective amounts of securities entitled to inclusion in
such registration held by all such Other Selling Stockholders and Holders at
the time of filing the Registration Statement. For purposes of the
apportionment provisions in clause (i) above, for any selling Holder that is a
partnership or corporation, the partners, retired partners, and shareholders
of such Holder, the estate and family members of such partners and retired
partners, and any trusts for the benefit of any of the foregoing persons shall
be deemed to be a single "selling Holder," and any pro rata reduction with
respect to such selling Holder shall be based upon the aggregate number of
shares carrying registration rights owned by all entities and individuals
included in such "selling Holder," as defined in this sentence. If any Other
Selling Stockholder or Holder disapproves of the terms of any such
underwriting, he may elect to withdraw therefrom by written notice to the
Company and the underwriter. Any securities excluded or withdrawn from such
underwriting shall be withdrawn from such registration.
 
  2.4 Expenses of Registration. All Registration Expenses incurred in
connection with any registration, qualification or compliance pursuant to this
Article 2 shall be borne by the Company; provided, however, that the
Registration Expenses for the fifth and all subsequent registrations under
Section 2.2(a) hereof requested by the Holders shall be borne by the
requesting Holders pro rata on the basis of the number of their shares so
registered. All Selling Expenses relating to the securities registered by
Holders and, if applicable, Other Selling Stockholders, and fees and
disbursements of counsel, shall be borne by the Holders or the Other Selling
Stockholders, as the case may be, of such securities pro rata on the basis of
the number of their shares so registered.
 
  2.5 Registration Procedures.
 
  (a) Company shall use its best efforts to register or qualify the
Registrable Securities covered by such Registration Statement under such other
securities or blue sky laws of such United States jurisdictions as Holder
shall reasonably request and do any and all acts and things which may be
necessary or desirable to enable Holder to consummate the public sale or other
disposition in such jurisdictions; provided, however, that Company shall not
be required in connection therewith or as a condition thereto to qualify to do
business or file a general consent to service of process in any such
jurisdictions.
 
  (b) The Company represents and warrants that, on the date of its
effectiveness, the Registration Statement will comply in all material respects
with the applicable requirements of the Securities Act and the rules
thereunder, including without limitation Rule 415; on the date of its
effectiveness, the Registration Statement will not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements made therein not
misleading; provided, however, that no
 
                                      B-7
<PAGE>
 
representation is made by Company with respect to information relative to any
Holder; and the Prospectus will not include any untrue statement of a material
fact or omit to state a material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading; provided, however, that no representation is made by Company
with respect to information relative to any Holder.
 
  (c) If, at any time or times while the Registration Statement is effective,
Company notifies Holder that a development has occurred or is pending which,
based upon consultation with Company's legal counsel, Company reasonably
believes may cause the then current Prospectus not to be in compliance with
applicable securities laws, then Holder shall refrain from delivering the
Prospectus and from making any offers or sales of Registrable Securities
requiring the delivery of the Prospectus until such time as Company either
notifies Holder that the Prospectus complies with such laws or delivers an
amended Prospectus in replacement of the deficient Prospectus. Company shall
use its reasonable best efforts to minimize the time during which Holder must
so refrain, and no more than one (1) such period of refrain shall be imposed
during any period of one hundred eighty (180) days.
 
  (d) At least two (2) business days prior to the initial filing of the
Registration Statement or Prospectus and no fewer than two (2) business days
prior to the filing of any amendment or supplement thereto (including any
document that would be incorporated or deemed to be incorporated therein by
reference), Company shall furnish Holder, its legal counsel and the managing
underwriter, if any, copies of all such documents proposed to be filed, which
documents (other than those incorporated or deemed to be incorporated by
reference) shall be subject to review of Holder, its legal counsel and such
underwriters, if any, and Company shall cause its officers and directors and
the independent certified public accountants to Company to respond to such
inquiries as shall be necessary, in the opinion of respective counsel to
Company and any such underwriters, to conduct a reasonable investigation
within the meaning of the Securities Act. Company shall not file any such
Registration Statement or Prospectus or any amendments or supplements thereto
to which Holder, its legal counsel, or the managing underwriters, if any,
shall reasonably object on a timely basis (i.e., within two (2) business days
of receipt thereof).
 
  (e) Company shall promptly notify Holder when the Registration Statement is
declared effective; notify Holder of any stop-order or similar proceeding by
the Commission or any state securities authority; and furnish such number of
Prospectuses, Prospectus supplements and other documents incident thereto as
Holder from time to time may reasonably request.
 
  (f) In the event of any breach by Company of the provisions of Section 2.2,
2.3, 2.4 or 2.5, the parties agree that Holder will suffer irreparable harm.
Accordingly, the parties agree that the provisions of Sections 2.2, 2.3, 2.4
and 2.5 are specifically enforceable by Holder and that Holder shall be
entitled to temporary and permanent injunctive relief against Company and the
other rights and remedies to which Holder may be entitled to at law, in equity
or under this Agreement for any such breach.

  (a) Indemnification by the Company. The Company shall indemnify each Holder

of or based on any untrue statement (or alleged untrue statement) of a
material fact contained in any Prospectus, offering circular or other document
(including any related Registration Statement, notification or the like)
incident to any such registration, qualification or compliance, or based on
any omission (or alleged omission) to state therein a material fact required
to be stated therein or necessary to make the statements therein not
misleading, or any violation by the Company of the Securities Act or any rule
or regulation thereunder applicable to the Company and relating to action or
inaction required of the Company in connection with any such registration,
qualification or compliance. The Company shall reimburse each such Holder,
each of its
 
                                      B-8
<PAGE>
 
officers, directors, employees, agents and partners, and each Person
controlling such Holder, each such underwriter and each Person who controls
any such underwriter for any legal and any other expenses reasonably incurred
in connection with investigating, preparing or defending any such expense,

shall not be liable in any such case to the extent that any such claim, loss,
damage, liability, action or expense arises out of or is based on any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by an
instrument duly executed by such Holder or underwriter and stated to be
specifically for use therein.
 
  (b) Indemnification by the Holders. To the extent set forth in the second
sentence of this Section 2.6(b), each Holder shall, if Registrable Securities
or other securities held by such Holder are included in the securities as to
which such registration, qualification or compliance is being effected,
indemnify the Company, each of its directors, officers, employees and agents,
each underwriter, if any, of the Company's securities covered by such a
Registration Statement, each Person who controls the Company or such
underwriter within the meaning of Section 15 of the Securities Act, each other
such Holder, each of such other Holder's officers, directors, employees,
agents and partners, and each Person controlling such Holder within the
meaning of Section 15 of the Securities Act against all expenses, claims,
losses, damages and liabilities (or actions in respect thereof), including any
of the foregoing incurred in settlement of any litigation, commenced or
threatened, arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact made by the Holder and contained in any such
Registration Statement, Prospectus, offering circular or other document, or
any amendment or supplement thereto or incident to any such registration,
qualification or compliance or based on any omission (or alleged omission) to
state therein a material fact required to be made by the Holder and stated
therein or necessary to make the statements therein not misleading or any
violation by the Company of any rule or regulation promulgated under the
Securities Act applicable to the Company in connection with such registration,
qualification or compliance as a result of any statement (or based on any
omission to state or alleged omission) required to be made by such Holder.
Each such Holder shall reimburse the Company, such other Holders, directors,
officers, employees, agents, partners, Persons, underwriters and control
persons for any legal or any other expenses reasonably incurred in connection
with investigating, preparing or defending any such expense, claim, loss,
damage, liability or action, in each case to the extent, but only to the
extent, that such untrue statement (or alleged untrue statement) or omission
(or alleged omission) is made in such Registration Statement, Prospectus,
offering circular or other document or any amendment or supplement thereto in
reliance upon and in conformity with written information furnished by the
Holder to the Company by an instrument duly executed by such Holder and stated
to be specifically for use therein; provided, however, that the obligations of
such Holders hereunder shall be limited to an amount equal to the proceeds to
each such Holder of Registrable Securities sold as contemplated herein in
connection with the particular registration, qualification or compliance
involved.
 
  (c) Notice. Each party entitled to indemnification under this Section 2.6
(the "Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified
Party has actual knowledge of any claim as to which indemnity may be sought
and shall permit the Indemnifying Party to assume the defense of any such
claim or any litigation resulting therefrom; provided, however, that counsel
for the Indemnifying Party, who shall conduct the defense of such claim or any
litigation resulting therefrom, shall be approved by the Indemnified Party
(whose approval shall not unreasonably be withheld), and that the Indemnified
Party may participate in such defense at its own expense; and provided further
that the failure of any Indemnified Party to give notice as provided herein
shall not relieve the Indemnifying Party of its obligations under this Section
2.6 unless such failure resulted in detriment to the Indemnifying Party. No
Indemnifying Party, in the defense of any such claim or litigation, shall,
except with the consent of each Indemnified Party, consent to entry of any
judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation.
 
  2.7 Information by Holder. Each Holder or Holders of Registrable Securities
in any registration shall furnish to the Company such information regarding
such Holder or Holders and the distribution proposed by

  of sale under Rule 144, the Company shall, upon written request of such
  Holder (such request to include sufficient detail as to establish how the
  Holder so qualifies under Rule 144), promptly remove any restrictive legend
  that may have been placed on any Restricted or Control Securities and issue
  Common Stock of the Company free of such restrictive or other legends.

register the Registrable Securities granted to each Holder by the Company
under Sections 2.2 and 2.3 hereof may be transferred or assigned to a
transferee or assignee in connection with the transfer or assignment of not
less than one million (1,000,000) shares of the Registrable Securities;
provided, however, that the Company shall be entitled to notice of any such
transfer of registration rights within thirty (30) days of the date such
transfer is effected.
 
  2.10 Limitations on Subsequent Registration Rights. No owner or prospective
owner of securities of the Company shall have any registration rights other
than as set forth in this Agreement. The Company shall not, without the prior
written consent of the Holders (which consent shall not be unreasonably
withheld) of not less than sixty-six and two-thirds percent (66 2/3%) of the
Registrable Securities then held by Holders, enter into any agreement with any
owner or prospective owner of any securities of the Company that would allow
such owner or prospective owner to include such securities in any registration
filed under this Article 2 if such inclusion would adversely affect the rights
of any Holder.
 
  2.11 Termination of Registration Rights. The registration rights granted
pursuant to this Article 2 shall terminate as to each Holder at such time as
(a) all Registrable Securities can be sold within a given three (3) month
period without compliance with the registration requirements of the Securities
Act pursuant to Rule 144 supported by a written opinion of legal counsel for
the Company, which opinion shall be reasonably satisfactory in form and
substance to legal counsel for such Holders, and (b) all accrued interest and
principal under the Company Credit Facility and the Gargiulo Credit Facility
has been repaid in full or converted into Common Stock of the Company (and
such Common Stock can be sold as provided in (a) above).
 
  2.12 "Market Stand-off" Agreement. Each Holder hereby agrees that, to the
extent requested by the Company and an underwriter of a sale of Common Stock
(or other securities) of the Company for the account of the Company and not
for the account of a security holder or holders exercising their respective
demand registration rights, it shall not sell or otherwise transfer or dispose
of (other than to transferees who agree to be similarly bound) any Registrable
Securities during the ninety (90) day period following the effective date of a
 
                                     B-10
<PAGE>
 
registration statement of the Company filed under the Securities Act;
provided, however, that all officers and directors of the Company, all Other
Selling Stockholders and all other Persons with registration rights (whether
or not pursuant to this Agreement) shall enter into similar agreements. To
enforce the foregoing covenant, the Company may impose stop-transfer
instructions with respect to the Registrable Securities of each Holder (and
the shares or securities of every other Person subject to the foregoing
restriction) until the end of such ninety (90) day period.
 
                                   ARTICLE 3
 
                 Anti-Dilution Rights and Limitations on Owner
 
  3.1 Anti-Dilution Rights. If, at any time after the Effective Date, Company
agrees to sell shares of its Common Stock or other Voting Stock ("Company
Securities") in a private or public offering (other than Company Securities
issued pursuant to the Company's stock option plans), Holder shall have the
right, but not the obligation, to acquire all or any portion of the Company
Securities sufficient for Holder to maintain, after the offering, the same
percentage of ownership of issued and outstanding Company Securities that
Holder possessed immediately prior to the offering (the "Pre-Offering
Percentage"). With respect to the issuance of Company Securities pursuant to
the Company's stock option plans, Holder shall have a right to maintain its
percentage ownership of issued and outstanding Company Securities by making
open market purchases as provided in Section 3.5 hereof.
 
  3.2 Private Offering. With respect to a private offering, other than
pursuant to a Company stock option plan, Company shall, within five (5)
business days after the execution of any agreement entered into in connection
with such private offering, notify Holder in writing of the proposed offering
and provide Holder with copies of all related documentation, including, for
example, any letter of intent and the final contract. Holder shall have twenty
(20) business days from the date of receipt of Company's notice in which to
advise Company whether Holder elects to exercise its rights under Section 3.1
hereof. If Holder does not respond, or if Holder indicates that it will not
exercise its rights, Holder shall be considered irrevocably to have waived its
rights under Section 3.1 hereof with respect to such specific private
offering. If Holder timely advises Company that Holder will exercise its
rights under Section 3.1 hereof, Holder shall have the right to acquire all or
any portion of the necessary amount of the Company Securities to maintain
Holder's Pre-Offering Percentage at the price or value of the consideration
specified in the private offering agreement entered into between Company and
the purchaser. Closing shall be in accordance with the terms of the private
offering agreement, and Holder shall make such investment representations to
Company and shall provide Company with such other documentation at closing as
is reasonably required by Company to comply with applicable securities laws.
 
  3.3 Public Offering. With respect to a public offering, Company shall notify
Holder no later than five (5) business days after Company has entered into a
letter of intent with its underwriters, and shall provide Holder with a copy
of the letter of intent. Holder shall have twenty (20) business days from the
date of receipt of Company's notice in which to advise Company whether Holder
elects to exercise its rights under Section 3.1 hereof. If Holder does not
respond or if Holder indicates that it will not exercise its rights, Holder
shall be considered irrevocably to have waived its rights under Section 3.1
hereof with respect to the public offering. If Holder timely advises Company
that Holder desires to retain its rights under Section 3.1 hereof, then, when
Company files a Registration Statement containing a Preliminary Prospectus
with the Commission, Company shall provide Holder with copies of the
Preliminary Prospectus and all subsequent amendments. Holder shall have twenty
(20) business days from its receipt of the Preliminary Prospectus in which to
exercise its rights under Section 3.1 hereof by making an offer to acquire all
or any portion of the necessary amount of Company Securities to maintain
Holder's Pre-Offering Percentage based on the price, less all Selling
Expenses, and the other terms contained in the final Prospectus. No such offer
to buy shall be accepted prior to the time that the Registration Statement
becomes effective. The Registration Statement shall indicate that Holder has
anti-dilution rights to purchase Company Securities on the terms offered to
the public.
 
  3.4 Limitations. Notwithstanding the preceding provisions of this Article 3,
Company shall not be required to issue any fractional shares as a result of
Holder's exercise of its rights under Section 3.1 hereof.
 
                                     B-11
<PAGE>
 
Company shall not be required to transfer any Company Securities to Holder
under this Article 3 if to do so would result in the violation of any
applicable law, rule or regulation.
 
  3.5 Open Market Purchases to Maintain Ownership Percentage. Notwithstanding
any other provision hereof, at any time after the Effective Date, Holder may
make such open market purchases of Company Securities as are necessary to
maintain Holder's percentage of ownership of issued and outstanding Company
Securities at forty-nine and nine-tenths percent (49.9%) (or such higher
percentage as may be permitted under Section 3.6 hereof) or to increase its
percentage of ownership of issued and outstanding Company Securities to forty-
nine and nine-tenths percent (49.9%) (or such higher percentage as may be
permitted under Section 3.6 hereof). With respect to the issuance of Company
Securities pursuant to a Company stock option plan or any warrant, conversion
right or other option, Company shall notify Holder no later than ten (10)
calendar days after the end of each calendar quarter and within ten (10)
calendar days of the record date for a shareholder meeting and for dividend
payments for Company Securities of the number of shares and issuance price of
Company Securities issued pursuant to Company's stock option plans or any
warrant, conversion right or other option subsequent to the last notice given
pursuant to this Section 3.5 so as to enable Holder to make open market
purchases of Company Securities as permitted under this Section 3.5.
 
  3.6 Limitations on Holder's Ownership. Except for purchases of Company
Securities made in accordance with this Article 3, during the term of this
Agreement, Holder shall not directly or indirectly acquire any Company
Securities except as follows:
 
    (a) Prior to the first anniversary of the Effective Date, Holder shall
  not increase its percentage of ownership of issued and outstanding Company
  Securities above forty-nine and nine-tenths percent (49.9%) except through

    Facility or the Gargiulo Credit Facility into shares of Common Stock;

    Company; and
 
      (iii) A tender offer by Holder for no less than one hundred percent
    (100%) of the publicly-traded Company Securities at a price approved by
    the disinterested Directors of Company and based upon a fairness
    opinion delivered to the Board of Directors of the Company by an
    investment banking firm.
 
    (b) On and after the first anniversary of the Effective Date until the
  earlier of September 30, 1998, or the third anniversary of the Effective

  (49.9%) except through one (1) or more of the following:
 
      (i) Conversion of principal and/or interest under the Company Credit
    Facility or the Gargiulo Credit Facility into shares of Common Stock;
 
      (ii) Issuance of Company Securities in an asset sale by Holder to
    Company; and
 
      (iii) A tender offer by Holder to increase its ownership to seventy
    percent (70%) or more of the issued and outstanding Company Securities
    at a price approved by the disinterested Directors of Company and based
    upon a fairness opinion delivered to the Board of Directors of the
    Company by an investment banking firm; provided, however, that, if
    Holder makes a tender offer to increase its ownership to more than
    eighty percent (80%) of the issued and outstanding Company Securities,
    such tender offer must be for one hundred percent (100%) of the
    publicly traded Company Securities.
 
    (c) After the earlier of September 30, 1998, or the third anniversary of
  the Effective Date, Holder may increase its ownership of Company Securities
  through open market purchases or otherwise.
 
                                     B-12
<PAGE>
 
    (d) If, at any time after the Effective Date, Holder shall elect to
  increase its percentage of ownership of issued and outstanding Company
  Securities above forty-nine and nine-tenths percent (49.9%) as provided in
  paragraphs (a) and/or (b) above (such increased percentage hereafter being
  the "New Percentage Ownership"), then thereafter Holder may make such open
  market purchases of Company Securities as are necessary to maintain such
  New Percentage Ownership or to increase its percentage of ownership of
  issued and outstanding Company Securities to such New Percentage Ownership.
 
    (e) Holder shall not be required to dispose of any Company Securities if
  Holder's percentage ownership of Company Securities is increased as a
  result of any recapitalization by Company or any other action taken by
  Company.
 
  3.7 Limitations on Holder's Resale of Company Securities. Holder shall not
directly or indirectly sell any Company Securities (other than to an Affiliate
of Holder) except as follows:
 
    (a) On and after the first anniversary of the Effective Date until the
  earlier of September 30, 1998, or the third anniversary of the Effective
  Date, Holder may sell Company Securities (i) as part of a joint venture,
  merger or sale of all or substantially all of its current Crop Protection
  business unit, as such business may be subsequently renamed or reorganized,
  or (ii) pursuant to a tender offer by a third party to the shareholders of
  Company.
 
    (b) After the earlier of September 30, 1998, or the third anniversary of

  Securities through a private sale of thirty-five percent (35%) or more of
  the total issued and outstanding Company Securities to a Non-Financial
  Purchaser under circumstances where such third party assumes the applicable
  and proportionate rights and obligations of Holder under this Agreement and
  the other Transaction Agreements.
 
    (d) Notwithstanding the foregoing, at any time after the Effective Date,
  Holder may sell Company Securities issued to Holder upon conversion by

                   Company and Calgene Corporate Governance
 
  4.1 Composition of the Board of Directors and Calgene Board. The composition
of the Board of Directors and of the Calgene Board and manner of selecting
members thereof shall be as follows:
 
    (a) At and after the Effective Date, each of the Board of Directors and
  the Calgene Board shall be comprised of nine (9) directors. The number of

  with Section 4.1(c) or Section 4.4(a)(xii) hereof. The parties agree that
  the composition of, and the governance provisions relating to, the Board of
  Directors and the Calgene Board shall be identical, and that the provisions
  of this Section 4.1 set forth below and of Sections 4.3(c) and 4.3(d)
  hereof shall be deemed to apply equally to the Calgene Board and Calgene
  Directors. Accordingly, when applied to the Calgene Board, the term
  "Director" shall be deemed to mean "Calgene Director", the term "Company",
  whether used alone or as a modifier, shall be deemed to mean "Calgene", and
  the term "Board of Directors" shall be deemed to mean "Calgene Board".
 
 
                                     B-13

    (b) At the Effective Date and until the occurrence of a Trigger Event,
  the Board of Directors shall consist of two (2) Company Management
  Directors, three (3) Company Directors designated by the Company, and four
  (4) Directors designated by Monsanto, at least one (1) of which is an
  Independent Director (consistent with Monsanto's current intent, the
  Directors to be designated by Monsanto (other than the Independent
  Director) will initially be Hendrik A. Verfaillie, Robert T. Fraley and
  Jeffrey D. Gargiulo).
 
    (c) At and after the occurrence of a Trigger Event, the Board of
  Directors shall be comprised of eleven (11) Directors and Monsanto shall,
  subject to paragraph (d) below, have the right to designate two (2)
  additional Directors for a total of six (6) Directors.
 
    (d) At any time that Monsanto's Percentage Interest is at least seventy
  percent (70%), (i) Monsanto shall have the right to designate eight (8)
  Directors, to consist of the two (2) Company Management Directors and six
  (6) other Monsanto Directors (including at least one (1) Independent
  Director) and (ii) the Company shall have the right to designate three (3)
  Independent Directors. At such time as Monsanto's Percentage Interest is at
  least ninety-nine percent (99%), Monsanto shall have the right to designate
  all of the Directors.
 
    (e) Notwithstanding anything in the foregoing paragraphs (b), (c) and (d)
  to the contrary, (i) at any time Monsanto's Percentage Interest is less
  than forty percent (40%) but at least twenty percent (20%), Monsanto shall
  have the right to designate three (3) Directors, (ii) at any time
  Monsanto's Percentage Interest is less than twenty percent (20%) but at
  least ten percent (10%), Monsanto shall have the right to designate two (2)
  Directors and (iii) at any time Monsanto's Percentage Interest is less than
  ten percent (10%) but at least five percent (5%), Monsanto shall have the
  right to designate one (1) Director. If, at any time, Monsanto's Percentage
  Interest is less than five percent (5%), Monsanto shall not have the right
  to designate any Director. At any such time, all other Directors, other
  than the Company Management Directors, shall be designated by the Company.
 
    (f) The Independent Directors to be designated by the Company from time
  to time shall be designated by action of a majority of the Company
  Directors then in office. In the event that no Company Directors are in
  office at such time, such Independent Directors shall be designated by a
  majority of the Independent Directors then in office; provided, however,
  that the holders of a majority of the outstanding Voting Stock held by
  Unaffiliated Equity Holders shall be entitled to nominate and elect Company
  Directors in lieu of any individuals so designated to be such Company
  Directors by a majority of the Company Directors.
 
    (g) The Company and Monsanto, respectively, shall have the right to
  designate any replacement for a Director designated in accordance with this
  Section 4.1 by the Company or Monsanto, respectively, upon the death,
  resignation, retirement, disqualification or removal from office for cause
  of such Director. Such replacement for any Independent Director shall also
  be an Independent Director unless, in the case of a replacement of a
  Monsanto Director, the Monsanto Directors include more than the required
  number of Independent Directors. The Board of Directors shall elect each
  person so designated by Monsanto or the Company pursuant to this paragraph
  (g). In addition, the Board of Directors shall elect the Company's Chief
  Executive Officer or Chief Operating Officer to replace such officer's
  predecessor in office as a Company Management Director.
 
    (h) In the event that, at any time after the Effective Date, the number
  of Monsanto Directors on the Board of Directors differs from the number
  that Monsanto has the right (and wishes) to designate pursuant to this
  Section 4.1, (i) if the number of Monsanto Directors exceeds such number,
  Monsanto shall promptly take all appropriate action to cause to resign that
  number of Monsanto Directors as is required to make the remaining number of
  such Monsanto Directors conform to this Section 4.1 or (ii) if the number
  of Monsanto Directors otherwise is less than such number, the Company shall
  promptly take all necessary action to create sufficient vacancies on the
  Board of Directors to permit Monsanto to designate the full number of
  Monsanto Directors which it is entitled (and wishes) to designate pursuant
  to this Section 4.1 (such action to include seeking the resignation or
  removal of Directors or, at the request of Monsanto, calling a special
  meeting of
 
                                     B-14
<PAGE>
 
  the stockholders of the Company for the purpose of removing Directors to
  create such vacancies to the extent permitted by applicable law). Upon the
  creation of any vacancy pursuant to the preceding sentence, Monsanto shall
  designate the person to fill such vacancy in accordance with this Section
  4.1 and the Board of Directors shall elect each person so designated.
  Notwithstanding the foregoing, at each annual meeting of the stockholders
  of the Company, Monsanto shall be entitled to designate such number of
  Directors as Monsanto is otherwise entitled under this Section 4.1.
 
    (i) Notwithstanding anything herein to the contrary, no individual who is
  an officer, director, employee, agent, partner or principal stockholder of
  any competitor of the Company or any of its Affiliates (other than Monsanto
  and its Affiliates) or any competitor of Monsanto or any of its Affiliates
  (other than the Company) shall serve as a Director without the unanimous
  consent of the Board.
 
    (j) In the event that, at any time after the Effective Date, Monsanto
  desires to remove any Monsanto Director with or without cause and Monsanto
  is unable to procure the resignation of such Monsanto Director, then, upon
  the request of Monsanto, the Board of Directors shall promptly call a
  special meeting of stockholders of the Company for purposes of removing
  such Monsanto Director. In the event that, at any time after the Effective
  Date, the Company desires to remove any Company Director with or without
  cause and the Company is unable to procure the resignation of such Company
  Director, then, upon the request of a majority of the Company Directors
  then in office (or, in the event no Company Directors are then in office,
  upon the request of a majority of the Independent Directors then in
  office), the Board of Directors shall promptly call a special meeting of
  stockholders of the Company for purposes of removing such Company Director.
  In the event that, at any time after the Effective Date, the Chief
  Executive Officer's or Chief Operating Officer's employment with the
  Company is terminated for any reason, then upon the request of either
  Monsanto or a majority of the Company Directors then in office (or, in the
  event no Company Directors are then in office, upon the request of a
  majority of the Independent Directors then in office), the Board of
  Directors shall promptly call a special meeting of stockholders of the
  Company for purpose of removing such person as a Company Management
  Director.
 
4.2. Solicitation and Voting of Shares.
 
  (a) The Company shall use its best efforts to solicit from the stockholders
of the Company eligible to vote for the election of Directors proxies in favor
of the Company Management Directors and the nominees designated in accordance
with Section 4.1 hereof or the removal of any Director pursuant to Section
4.1(h) or 4.1(j) hereof.
 
  (b) In any election of Directors or any meeting of the stockholders of the
Company called expressly for the removal of Directors, so long as the Board of
Directors includes (and will include after any such removal) the number of
Monsanto Directors contemplated by Section 4.1 hereof and so long as such
meeting is properly called and Monsanto is properly notified in accordance
with the Company's by-laws and certificate of incorporation, Monsanto and its
Affiliates shall attend such meeting for purposes of establishing a quorum and
shall vote all their shares of Voting Stock (i) in favor of any nominee or
Director designated in accordance with Section 4.1 hereof, (ii) in favor of
removal of any Director as contemplated by Section 4.1(h) or 4.1(j) hereof,
and (iii) otherwise against the removal of any Director designated in
accordance with Section 4.1 hereof (other than in cases of removal of a
Director for cause); provided, however, that, if Monsanto and its Affiliates
elect to cumulate their votes in accordance with the Company's by-laws and
certificate of incorporation, then, in any vote electing Monsanto Directors,
Monsanto and its Affiliates may cast all of their votes in favor of one (1) or
more of the Monsanto Directors designated by Monsanto and in any vote with
respect to the removal of a Monsanto Director, Monsanto and its Affiliates may
cast all or any portion of their votes either in favor or against the removal
of any Monsanto Director unless a Monsanto Director is otherwise required to
be removed in accordance with Section 4.1(h) hereof. In any other matter
submitted to a vote of the stockholders of the Company, Monsanto and its
Affiliates may vote any or all of their shares in their sole discretion.
 
  (c) Monsanto agrees that it will, and will cause any of its Subsidiaries
(other than the Company and its Subsidiaries) to, take all action as a
stockholder of the Company or as is otherwise reasonably within its control,
 
                                     B-15
<PAGE>
 
as necessary to effect the provisions of this Agreement; provided, however,
that, if Monsanto cannot so take actions to give effect to all of the
provisions of this Agreement, it may first take actions to ensure that it
receives all of its benefits hereunder and then, to the extent possible, to
give effect to the provisions in favor of the Company.
 
 
  4.3. Committees.
 
  (a) The Board of Directors shall establish, empower and maintain the
committees of the Board of Directors contemplated by this Section 4.3.
 
  (b) The following committees shall be established, empowered and maintained
by the Board of Directors at all times during the term of this Agreement:
 
    (i) an Audit Committee, consisting of at least three (3) of the Company's
  Independent Directors, which committee shall be authorized and empowered to
  cause an audit to be performed of the Company and each of its Subsidiaries;
 
    (ii) until the occurrence of a Trigger Event, a Retention/Replacement
  Committee, consisting of the Independent Directors then serving on the
  Board, responsible for the retention and/or replacement of all of the
  executive officers of the Company, to be based on the financial and
  behavioral criteria established by the Retention/Replacement Committee; in
  the event that such committee decides to replace any executive officer,
  Monsanto shall have the right to nominate a replacement for such executive
  officer for consideration by the committee along with any other candidates
  identified by such committee; the rights of the Retention/Replacement
  Committee shall be subject to the provisions set forth in Section
  4.4(a)(viii) hereof;
 
    (iii) a Compensation Committee, responsible, among other things, for
  recommending to the Board of Directors, for approval by a majority of the
  Board of Directors, (a) the adoption and amendment of all employee benefit
  plans and arrangements, (b) the engagement of, terms of any employment
  agreements and arrangements with, and termination of, all persons
  designated by the Company as "officers" for purposes of Section 16 of the
  Exchange Act ("Section 16 Officers"), (c) the policies, limitations and
  procedures under which the Stock Option Plan Administration Committee shall
  operate and (d) the granting under the Company's employee benefit plans of
  stock options and other equity rights to Section 16 Officers, and
  consisting solely of the Independent Directors then serving on the Board
  provided each such Independent Director is (A) a disinterested person (as
  such term is defined in rule 16b-3(d) under the Exchange Act) and (B) an
  "independent director" for purposes of Section 162(m) of the Internal
  Revenue Code of 1986, as amended; and
 
    (iv) such other committees as the Board of Directors deems necessary or
  desirable; provided, however, that such committees are established in
  compliance with Section 4.4(a)(vi) hereof.
 
  For purpose of clause (ii) above, "executive officers" shall have the same
meaning as in Rule 3b-7 promulgated under the Exchange Act.
 
  (c) Except as otherwise provided in Section 4.3(b) hereof or as agreed by a
majority of the Monsanto Management Directors, the number of Monsanto
Directors on each committee of the Board of Directors shall be the same
proportion (but not less than one (1)) of the total membership of such
committee as the number of Monsanto Directors, as the case may be, is of the
entire Board of Directors. Except as otherwise provided in Section 4.3(b)
hereof, the Monsanto Directors on each committee of the Board of Directors
shall be determined by a majority of the Monsanto Management Directors.
 
  (d) No action by any committee of the Board of Directors shall be valid
unless taken by unanimous written consent as provided in the Company's by-laws
or taken at a meeting for which adequate notice has been duly given or waived
by the members of such committee. Such notice shall include a description of
the general nature of the business to be transacted at the meeting, and no
other business may be transacted at such meeting unless all members of the
committee are present and consent to the consideration of such other business.
Any committee

Management Director to replace any absent or disqualified Independent Director
member or Company Management Director member, respectively, of any committee
and a majority of the Monsanto Management Directors shall designate a Monsanto
Director to replace any absent or disqualified Monsanto Director member of any
committee. Each of the committees established by the Board of Directors
pursuant to this Section 4.3 shall establish such other rules and procedures
for its operation and governance (consistent with the terms of this Agreement)
as it shall see fit and may seek such consultation and advice as to matters
within its purview as it shall require.

shall take or cause to be taken all lawful action necessary to ensure at all
times that the Company's and Calgene's Certificate of Incorporation and By-

October 5, 1995
 
Members of the Board of Directors
Calgene, Inc.
1920 Fifth Street
Davis, CA 95616
 
Gentlemen:
 
  We understand that Calgene, Inc., a Delaware corporation (the "Company"),
and Monsanto Company, a Delaware corporation ("Monsanto"), expect to enter
into an Agreement and Plan of Reorganization to be dated on or about October
13, 1995 (the "Agreement"). Pursuant to the terms of the Agreement, a new
holding company ("Newco") will be created by the Company and Monsanto.
Immediately prior to the closing, Tomato Investment Associates, Inc. ("TIA"),
which is a subsidiary of Monsanto, will acquire all of the partnership
interests of NT Gargiulo L.P. ("Gargiulo"). At the closing, (i) a wholly-owned
subsidiary of Newco will merge with the Company, the Company will become a
wholly-owned subsidiary of Newco, each outstanding share of the common stock,
par value $.001 per share, of the Company (the "Calgene Common Stock") will be
exchanged for one share of Newco Common Stock (constituting in the aggregate
50.1% of the outstanding shares of Newco Common Stock after the closing), and
each outstanding share of the Preferred Stock, Series A, par value $.001 per
share, of the Company will be exchanged for one share of Preferred Stock,
Series A, par value $.001 per share of Newco; (ii) Monsanto will exchange all
of the capital stock of TIA, plus certain intellectual property and research
and development assets (the "R&D Assets") and a combination of cash and
forgiveness of debt in the aggregate amount of $30,000,000 (the "Cash")
(collectively, the "Monsanto Consideration"), for shares of the common stock,
par value $.001 per share, of Newco (the "Newco Common Stock") constituting
49.9% of the outstanding shares of Newco Common Stock after the closing; and
(iii) Newco will change its name to "Calgene, Inc." Immediately following the
closing under the Agreement, Gargiulo will be liquidated into TIA. In
connection with the closing, Monsanto and Newco will enter into a
stockholders' agreement which gives Monsanto certain rights regarding
corporate governance, registration of shares of Newco Common Stock held by
Monsanto and other matters. Monsanto will also enter into separate lending
agreements with Newco and Gargiulo pursuant to which outstanding loan amounts
may, under certain circumstances, be converted into shares of Newco Common
Stock.
 
  You have asked us for our opinion as investments bankers as to whether the
Monsanto Consideration to be received by Newco in exchange for 49.9% of the
Newco Common Stock pursuant to the Agreement is fair to the Company from a
financial point of view, as of the date hereof.
 
  In connection with our opinion, we have, among other things: (i) reviewed
certain publicly available financial and other data with respect to the
Company, including the Company's consolidated financial statements for recent
years and interim periods to June 30, 1995, and certain other relevant
financial and operating data relating to the Company and Gargiulo made
available to us from published sources and from the internal records of the
Company, Gargiulo and Monsanto, including Gargiulo's consolidated financial
statements for recent years and interim periods to June 30, 1995; (ii)
reviewed the September 29, 1995 draft of the Agreement provided to us by the
Company; (iii) reviewed certain historical market prices and trading volumes
of the Company Common Stock on the NASDAQ National Market; (iv) analyzed the
financial impact the transactions contemplated by the Agreement are expected
to have on the projected results of the Company; (v) reviewed and discussed
with representatives of the management of the Company, Gargiulo and Monsanto
certain information of a business
 
                                      C-1
<PAGE>
 
and financial nature regarding the Company and Gargiulo, furnished to us by
them, including financial forecasts and related assumptions of the Company and
Gargiulo; (vi) made inquiries regarding and discussed the Agreement and other
matters related thereto with the Company's counsel; and (vii) performed such
other analyses and examinations as we have deemed appropriate.
 
  In connection with our review, we have relied upon the accuracy and
completeness of the foregoing information and we have not assumed any
responsibility independently to verify such information. With respect to the
financial forecasts for the Company and Gargiulo provided to us by the
management of the Company and Monsanto, respectively, we have assumed for
purposes of our opinion that the forecasts have been reasonably prepared on
bases reflecting the best available estimates and judgments of the respective
managements at the time of preparation as to the future financial performance
of the Company and Gargiulo, and that they provide a reasonable basis upon
which we can form our opinion. We have also assumed that there have been no
material changes in the Company's, Gargiulo's or TIA's assets, financial
condition, results of operations, business or prospects since the respective
dates of their last financial statements made available to us, except for
Gargiulo's pending acquisition of Collier Farms. We have relied on advice of
counsel and independent accountants to the Company as to all legal and
financial reporting matters with respect to the Company and the Agreement. We
have assumed that you will consummate the transactions contemplated by the
Agreement in a manner that complies in all respects with the applicable
provisions of the Securities Act of 1933, as amended (the "Securities Act")
and the Securities Exchange Act of 1934, as amended and all other applicable
federal and state statutes, rules and regulations. In addition, we have not
assumed responsibility for making an independent evaluation, appraisal or
physical inspection of the assets or liabilities (contingent or otherwise) of
the Company, Gargiulo or TIA, nor have we been furnished with any such
appraisals. Finally, our opinion is based on economic, monetary and market and
other conditions as in effect on, and the information made available to us as
of, the date hereof.
 
  We have further assumed, with your consent, that the transactions
contemplated by the Agreement will be consummated in accordance with the terms
described in the Agreement without any amendments thereto, and without waiver
by the Company or Monsanto of any of the conditions to their respective
obligations thereunder.
 
  In the ordinary course of our business, we actively trade the equity
securities of the Company and Monsanto for our own account and for the account
of our customers and, accordingly, may at any time hold a long or short
position in such securities. We have also performed various investment banking
services for the Company, including acting as co-manager of an underwritten
public offering of Calgene Common Stock in January 1993 and lead manager of an
underwritten public offering of Calgene Common Stock in October 1994. Certain
partners of Montgomery also own shares of the Company's and Monsanto's common
stock.
 
  Based upon the foregoing and in reliance thereon, it is our opinion as
investment bankers that the Monsanto Consideration to be received by Newco in
exchange for 49.9% of the Newco Common Stock pursuant to the Agreement is fair
to the Company from a financial point of view, as of the date hereof.
 
  This opinion is furnished pursuant to our engagement letter, dated January
18, 1995. This opinion is addressed to the Board of Directors of the Company
only and is not intended to be and shall not be deemed to be a recommendation
to any shareholder as to how such shareholder should vote with respect to the
transactions contemplated by the Agreement. Except as provided in such
engagement letter, this opinion may not be used or referred to by the Company,
or quoted or disclosed to any person in any manner, without our prior written
consent. In furnishing this opinion, we do not admit that we are experts
within the meaning of the term "experts" as used in the Securities Act and the
rules and regulations promulgated thereunder, nor do we admit that this
opinion constitutes a report or valuation within the meaning of Section 11 of
the Securities Act.
 
                                          Very truly yours,
 
                                          Montgomery Securities

omitted by such officer or director with respect to an employee benefit plan
reasonably believed by such person to be in the interest of the participants
and beneficiaries of the plan shall be deemed to be for a purpose which is not
opposed to the best interests of the Registrant.

ITEM 22. UNDERTAKINGS.
 
  A. Insofar as indemnification for liabilities arising under the Securities
Act of 1933 (the "Securities Act") may be permitted to directors, officers and
controlling persons of the Registrant pursuant to the foregoing provisions, or
otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is therefore unenforceable. In
the event that a claim for indemnification against such liabilities (other
than the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
  B. The Registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the Registrant's annual
report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange
Act of 1934 (the "Exchange Act") (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Exchange Act) that is incorporated by reference in this Registration Statement
shall be deemed to be a new registration statement relating to the securities
offered herein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.
 
  C. The Registrant hereby undertakes as follows:
 
  (1) That prior to any public reoffering of the securities registered
hereunder through use of a prospectus which is a part of this Registration
Statement, by any person or party who is deemed to be an underwriter within
the meaning of Rule 145(c), the Registrant undertakes that such reoffering
prospectus will contain the information called for by the applicable
registration form with respect to reofferings by persons who may be deemed
underwriters, in addition to the information called for by the other Items of
the applicable form.
 
  (2) That every prospectus (i) that is filed pursuant to paragraph (1)
immediately preceding, or (ii) that purports to meet the requirements of
Section 10(a)(3) of the Securities Act and is used in connection with an
offering of securities subject to Rule 415, will be filed as a part of an
amendment to this Registration Statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act, each such post-effective amendment shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.
 
  D. The Registrant hereby undertakes to respond to requests for information
that is incorporated by reference into the prospectus pursuant to Items 4,
10(b), 11, or 13 of this Form, within one business day of receipt of such
request, and to send the incorporated documents by first class mail or other
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of this Registration Statement through the
date of responding to the request.
 
  E. The Registrant hereby undertakes to supply by means of a post-effective
amendment all information concerning a transaction, and the company being
acquired involved therein, that was not the subject of and included in this
Registration Statement when it became effective.
 
                                     II-4
<PAGE>
 
  F. The Registrant hereby undertakes as follows:
 
  (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:
 
   (i) To include any prospectus required by Section 10(a)(3) of the
Securities Act;
 
   (ii) To reflect in the prospectus any facts or events arising after the
effective date of the registration statement (or the most recent post-
effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the
registration statement;
 
   (iii) To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information set forth in the registration statement;
 
    Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply
  if the registration statement is on Form S-3 or Form S-8, and the
  information required to be included in a post-effective amendment by those
  paragraphs is contained in periodic reports filed by the registrant
  pursuant to Section 13 or Section 15(d) of the Exchange Act that are
  incorporated by reference in the registration statement.
 
  (2) That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.
 
  (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of
the offering.

<PAGE>
 
     SEVENTH. Whenever a compromise or arrangement is proposed between this
corporation and its creditors or any class of them and/or between this
corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of this corporation or of any creditor or stockholder thereof, or on the
application of any receiver or receivers appointed for this corporation under
the provisions of section 291 of Title 8 of the Delaware Code or on the
application of trustees in dissolution or of any receiver or receivers appointed
for this corporation under the provisions of section 279 of Title 8 of the
Delaware Code order a meeting of the creditors or class of creditors, and/or of
the stockholders or class of stockholders of this corporation, as the case may
be, to be summoned in such manner as the said court directs. If a majority in
number representing three-fourths in value of the creditors or class of
creditors, and/or of the stockholders or class of stockholders of this
corporation, as the case may be, agree to any compromise or arrangement and to
any reorganization of this corporation as consequence of such compromise or
arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
be binding on all the creditors or class of creditors, and/or on all the
stockholders or class of stockholders, of this corporation, as the case may be,
and also on this corporation.

     EIGHTH. Except to the extent that the General Corporation Law of Delaware 
prohibits the elimination or limitation of liability of directors for breaches 
of fiduciary duty, no director of the Corporation shall be personally liable to 
the Corporation or its stockholders for monetary damages for any breach of 
fiduciary duty as a director, notwithstanding any provision of law imposing such
liability. No amendment to or repeal of this provision shall apply to or have 
any effect on the liability or alleged liability of any director of the 
Corporation for or with respect to any acts or omissions of such director 
occurring prior to such amendment.

     NINTH. The Corporation shall, to the fullest extent permitted by Section
145 of the General Corporation Law of Delaware, as amended from time to time,
indemnify each person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative, by reason of the fact that he
is or was, or has agreed to become, a director or officer of the Corporation, or
is or was serving, or has agreed to serve, at the request of the Corporation, as
a director, officer or trustee of, or in a similar capacity with, another
corporation, partnership, joint venture, trust or other enterprise (including
any employee benefit plan) (all such persons

                                      -2-
<PAGE>
 
being referred to hereafter as an "Indemnitee'), or by reason of any action 
alleged to have been taken or omitted in such capacity, against all expenses 
(including attorneys' fees), judgments, fines and amounts paid in settlement 
actually and reasonably incurred by or on behalf of an Indemnitee in connection 
with such action, suit or proceeding and any appeal therefrom.

      As a condition precedent to his right to be indemnified, the Indemnitee 
must notify the Corporation in writing as soon as practicable of any action, 
suit, proceeding or investigation involving him for which indemnity will or 
could be sought. With respect to any action, suit, proceeding or investigation 
of which the Corporation is so notified, the Corporation will be entitled to 
participate therein at its own expense and/or to assume the defense thereof at 
its own expense, with legal counsel reasonably acceptable to the Indemnitee.

      In the event that the Corporation does not assume the defense of any 
action, suit, proceeding or investigation of which the Corporation receives 
notice under this Article, the Corporation shall pay in advance of the final 
disposition of such matter any expenses (including attorneys' fees) incurred by 
an Indemnitee in defending a civil or criminal action, suit, proceeding or 
investigation or any appeal therefrom; provided, however, that the payment of 
                                       --------  -------
such expenses incurred by an Indemnitee in advance of the final disposition of 
such matter shall be made only upon receipt of an undertaking by or on behalf of
the Indemnitee to repay all amounts so advanced in the event that it shall 
ultimately be determined that the Indemnitee is not entitled to be indemnified 
by the Corporation as authorized in this Article, which undertaking shall be 
accepted without reference to the financial ability of the Indemnitee to make 
such repayment; and further provided that no such advancement of expenses shall
                    ------- --------
be made if it is determined that the Indemnitee did not act in good faith and in
a manner he reasonably believed to be in, or not opposed to, the best interests
of the Corporation, and, with respect to any criminal action or proceeding, had 
no reasonable cause to believe his conduct was unlawful.

      The Corporation shall not indemnify an Indemnitee seeking indemnification 
in connection with a proceeding (or part thereof) initiated by such Indemnitee 
unless the initiation thereof was approved by the Board of Directors of the 
Corporation. In addition, the Corporation shall not indemnify an Indemnitee to 
the extent such Indemnitee is reimbursed from the proceeds of insurance, and in 
the event the Corporation makes any indemnification payments to an Indemnitee 
and such Indemnitee is subsequently reimbursed from the proceeds of insurance, 
such Indemnitee shall promptly refund such indemnification payments to the 
Corporation to the extent of such insurance reimbursement.

                                      -3-
<PAGE>
 
    All determinations hereunder as to the entitlement of an Indemnitee to 
indemnification or advancement of expenses shall be made in each instance by (a)
a majority vote of the directors of the Corporation consisting of persons who 
are not at that time parties to the action, suit or proceeding in question 
("disinterested directors"), whether or not a quorum, (b) a majority vote of a 
quorum of the outstanding shares of stock of all classes entitled to vote for 
directors, voting as a single class, which quorum shall consist of stockholders
who are not at that time parties to the action, suit or proceeding in question,
(c) independent legal counsel (who may, to the extent permitted by law, be 
regular legal counsel to the Corporation), or (d) a court of competent 
jurisdiction.

    The indemnification rights provided in this Article (i) shall not be deemed 
exclusive of any other rights to which an Indemnitee may be entitled under any 
law, agreement or vote of stockholders or disinterested directors or otherwise, 
and (ii) shall inure to the benefit of the heirs, executors, and administrators 
of the Indemnitees. The Corporation may, to the extent authorized from time to 
time by its Board of Directors, grant indemnification rights to other employees 
or agents of the Corporation or other persons serving the Corporation and such 
rights may be equivalent to, or greater or less than, those set forth in this 
Article.

    TENTH. The Corporation reserves the right to amend, alter, change or repeal 
any provision contained in this Certificate of Incorporation, in the manner now 
or hereafter prescribed by statute and this Certificate of Incorporation, and 
all rights conferred upon stockholders herein are granted subject to this 
reservation.

    EXECUTED on November 21, 1995.

<PAGE>
 
     3. Dividends. Dividends may be declared and paid on the Common Stock from
        ---------
funds lawfully available therefor as and when determined by the Board of
Directors and subject to any preferential dividend rights of any then
outstanding Preferred Stock.

     4. Liquidation. Upon the dissolution or liquidation of the Corporation,
        -----------
whether voluntary or involuntary, holders of Common Stock will be entitled to
receive all assets of the Corporation available for distribution to its

B.   PREFERRED STOCK. 
     ---------------

     Preferred Stock may be issued from time to time in one or more series, each
of such series to have such terms as stated or expressed herein and in the
resolution or resolutions providing for the issue of such series adopted by the
Board of Directors of the Corporation as hereinafter provided. Any shares of

for the purposes of voting by classes unless expressly provided.

     Authority is hereby expressly granted to the Board of Directors from time
to time to issue the Preferred Stock in one or more series, and in connection
with the creation of any such series, by resolution or resolutions providing for
the issue of the shares thereof, to determine and fix such voting powers, full

participating, optional or other special rights, and qualifications, limitations

equally or be junior to the Preferred Stock of any other series to the extent
permitted by law. Except as otherwise provided in this Certificate of
Incorporation, no vote of the holders of the Preferred Stock or Common Stock
shall be a prerequisite to the designation or issuance of any shares of any
series of the

<PAGE>
 
Preferred Stock authorized by and complying with the conditions of this
Certificate of Incorporation, the right to have such vote being expressly waived

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

     A.1  Designation and Amount. The designation of this series of capital

any time on or prior to December 31, 1999 for $1.00 per share. In the event of
any redemption of only a part of the then outstanding Series A Stock, the
Corporation shall effect such redemption pro rata among the holders thereof
based on the number of shares of Series A Stock held by such holders on the date
that notice of redemption is given by the Corporation. At least 30 days prior to
the date fixed for any redemption of Series A Preferred Stock (a "Redemption
Date"), written notice shall be mailed, by first class or registered mail,
postage prepaid, to each holder of record of Series A Stock to be redeemed, at
his or its address last shown on the records of the Corporation, notifying such
holder of the election of the Corporation to redeem such shares and specifying
the Redemption Date. On or prior to the Redemption Date, each holder of Series A
Stock to be redeemed shall surrender his or its certificate or certificates
representing such shares to the Corporation in the manner and at the place
designated in the notice of redemption, and thereupon the redemption price of
such shares shall be payable to the order of the person whose name appears on
such certificate or certificates as the owners thereof, and each surrendered
certificate shall be cancelled. From and after the Redemption Date, all rights
of the holders of Series A Stock designated for redemption in the notice of
redemption as holders of Series A Stock of the Corporation (except to receive
the redemption price without interest upon surrender of their certificate or
certificates) shall cease with respect to such shares, and such shares shall not
thereafter deem to be outstanding for any purpose whatsoever.

                                      -3-
<PAGE>
 
     A.4  Conversion. The Series A Stock may not be converted into shares of

Common Stock or any other class or series of capital stock of the Corporation.

     A.5  Liquidation. In the event of any liquidation, dissolution or 
          -----------
winding-up of the Corporation (collectively, a "Liquidation"), the holders of
shares of Series A Stock shall be entitled to receive out of the assets of the
Corporation legally available for distribution to stockholders, whether from
capital, earnings or surplus, before payment shall be made to the holders of
Common Stock or any class or series of stock ranking on Liquidation junior to
such Series A Stock, $1.00 per share.

     A.6  Dividends. Dividends may be declared and paid on the Common Stock from
          ---------
funds lawfully available therefor, as and when determined by the Board of
Directors.

     FIFTH. In furtherance of and not in limitation of powers conferred by

designated by the Board of Directors.

     4. At all elections of directors of the Corporation, each holder of stock
or of any class or classes or of a series thereof shall be entitled to as many
votes as shall equal the number of votes which (except for this provision as to
cumulative voting) he would be entitled to cast for the election of directors
with respect to the shares of stock multiplied by the number of directors to be
elected, and he may cast all of such votes for a single candidate or may
distribute them among such number to be elected, or for any two or more of them
as he may see fit.

such date as Monsanto's Percentage Interest is less than twenty-five percent
(25%), the actions described in Section 4.4(a) of the Governance Agreement shall
require for approval the vote of the directors as set forth in Section 4.4(a) of
the Governance Agreement.

     During the term of the Governance Agreement and at all times following the
occurrence of a Trigger Event and until the earlier of (i) March __, 1999, or
(ii) such time as Monsanto's Percentage

                                      -5-
<PAGE>
 
Interest is at least seventy percent (70%), the actions described in Section
4.4(b) of the Governance Agreement shall require for approval the vote of the
directors as set forth in Section 4.4(b) of the Governance Agreement.

     During the term of the Governance Agreement and at all times following both
(i) the occurrence of a Trigger Event and (ii) March __, 1999, and until
Monsanto's Percentage Interest is at least ninety-nine percent (99%), the
actions described in Section 4.4(c) of the Governance Agreement shall require
for approval the vote of the directors as set forth in Section 4.4(c) of the
Governance Agreement.

     Any inconsistency between other provisions of this Certificate of
Incorporation or the By-laws of the Corporation and the provisions of the
Governance Agreement relating to the such approvals shall be resolved in favor
of the Governance Agreement.

D.   ANTI-DILUTION RIGHTS
     --------------------

     During the term of the Governance Agreement, if at any time the Corporation
agrees to sell shares of its Common Stock or other Voting Stock (collectively,
"Additional Securities") in a private or public offering (other than Additional
Securities issued pursuant to the Corporation's option or stock purchase plans)
Monsanto shall have the right, but not the obligation, to acquire all or any
portion of the Additional Securities as set forth in Article 3 of the Governance
Agreement.

     SIXTH. Whenever a compromise or arrangement is proposed between this
corporation and its creditors or any class of them and/or between this
corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of this corporation or of any creditor or stockholder thereof, or on the
application of any receiver or receivers appointed for this corporation under
the provisions of section 291 of Title 8 of the Delaware Code or on the
application of trustees in dissolution or of any receiver or receivers appointed
for this corporation under the provisions of section 279 of Title 8 of the
Delaware Code order a meeting of the creditors or class of creditors, and/or of
the stockholders or class of stockholders of this corporation, as the case may
be, to be summoned in such manner as the said court directs. If a majority in
number representing three-fourths in value of the creditors or class of
creditors, and/or of the stockholders or class of stockholders of this
corporation, as the

                                      -6-
<PAGE>
 
case may be, agree to any compromise or arrangement and to any reorganization of
this corporation as consequence of such compromise or arrangement, the said
compromise or arrangement and the said reorganization shall, if sanctioned by
the court to which the said application has been made, be binding on all the
creditors or class of creditors, and/or on all the stockholders or class of
stockholders, of this corporation, as the case may be, and also on this
corporation.

     SEVENTH. Except to the extent that the General Corporation Law of Delaware
prohibits the elimination or limitation of liability of directors for breaches
of fiduciary duty, no director of the Corporation shall be personally liable to
the Corporation or its stockholders for monetary damages for any breach of
fiduciary duty as a director, notwithstanding any provision of law imposing such
liability. No amendment to or repeal of this provision shall apply to or have
any effect on the liability or alleged liability of any director of the
Corporation for or with respect to any acts or omissions of such director
occurring prior to such amendment.

     EIGHTH.  1. Actions, Suits and Proceedings Other than by or in the Right of
                 ---------------------------------------------------------------
the Corporation. The Corporation shall indemnify each person who was or is a
- - ---------------
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the Corporation), by
reason of the fact that he is or was, or has agreed to become, a director or
officer of the Corporation, or is or was serving, or has agreed to serve, at the
request of the Corporation, as a director, officer or trustee of, or in a
similar capacity with, another corporation, partnership, joint venture, trust or
other enterprise (including any employee benefit plan) (all such persons being
referred to hereafter as an "Indemnitee"), or by reason of any action alleged to
have been taken or omitted in such capacity, against all expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him or on his behalf in connection with such action, suit
or proceeding and any appeal therefrom, if he acted in good faith and in a
manner he reasonably believed to be in, or not opposed to, the best interests of
the Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
        ---- ----------
presumption that the

                                      -7-
<PAGE>
 
person did not act in good faith and in a manner which he reasonably believed to
be in, or not opposed to, the best interests of the Corporation, and, with
respect to any criminal action or proceeding, had reasonable cause to believe
that his conduct was unlawful. Notwithstanding anything to the contrary in this
Article, except as set forth in Section 7 below, the Corporation shall not
indemnify an Indemnitee seeking indemnification in connection with a proceeding
(or part thereof) initiated by the Indemnitee unless the initiation thereof was
approved by the Board of Directors of the Corporation. Notwithstanding anything
to the contrary in this Article, the Corporation shall not indemnify an
Indemnitee to the extent such Indemnitee is reimbursed from the proceeds of
insurance, and in the event the Corporation makes any indemnification payments
to an Indemnitee and such Indemnitee is subsequently reimbursed from the
proceeds of insurance, such Indemnitee shall promptly refund such
indemnification payments to the Corporation to the extent of such insurance
reimbursement.

     2.  Actions or Suits by or in the Right of the Corporation. The Corporation
         ------------------------------------------------------
shall indemnify any Indemnitee who was or is a party or is threatened to be made
a party to any threatened, pending or completed action or suit by or in the
right of the Corporation to procure a judgment in its favor by reason of the
fact that he is or was, or has agreed to become, a director or officer of the
Corporation, or is or was serving, or has agreed to serve, at the request of the
Corporation, as a director, officer or trustee of, or in a similar capacity
with, another corporation, partnership, joint venture, trust or other enterprise
(including any employee benefit plan), or by reason of any action alleged to
have been taken or omitted in such capacity, against all expenses (including
attorneys' fees) and, to the extent permitted by law, amounts paid in settlement
actually and reasonably incurred by him or on his behalf in connection with such
action, suit or proceeding and any appeal therefrom, if he acted in good faith
and in a manner he reasonably believed to be in, or not opposed to, the best
interests of the Corporation, except that no indemnification shall be made in
respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to the Corporation unless and only to the extent that the
Court of Chancery of Delaware shall determine upon application that, despite the
adjudication of such liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses
(including attorneys' fees) which the Court of Chancery of Delaware shall deem
proper.

                                      -8-
<PAGE>
 
     3.  Indemnification for Expenses of Successful Party. Notwithstanding the
         ------------------------------------------------
other provisions of this Article, to the extent that an Indemnitee has been
successful, on the merits or otherwise, in defense of any action, suit or
proceeding referred to in Sections 1 and 2 of this Article, or in defense of any
claim, issue or matter therein, or on appeal from any such action, suit or
proceeding, he shall be indemnified against all expenses (including attorneys'
fees) actually and reasonably incurred by him or on his behalf in connection
therewith. Without limiting the foregoing, if any action, suit or proceeding is
disposed of, on the merits or otherwise (including a disposition without
prejudice), without (i) the disposition being adverse to the Indemnitee, (ii) an
adjudication that the Indemnitee was liable to the Corporation, (iii) a plea of
guilty or nolo contendere by the Indemnitee, (iv) an adjudication that the
          ---- ----------
Indemnitee did not act in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the Corporation, and (v) with
respect to any criminal proceeding, an adjudication that the Indemnitee had
reasonable cause to believe his conduct was unlawful, the Indemnitee shall be
considered for the purposes hereof to have been wholly successful with respect
thereto.

     4.  Notification and Defense of Claim. As a condition precedent to his 
         ---------------------------------
right to be indemnified, the Indemnitee must notify the Corporation in writing
as soon as practicable of any action, suit, proceeding or investigation
involving him for which indemnity will or could be sought. With respect to any
action, suit, proceeding or investigation of which the Corporation is so
notified, the Corporation will be entitled to participate therein at its own
expense and/or to assume the defense thereof at its own expense, with legal
counsel reasonably acceptable to the Indemnitee. After notice from the
Corporation to the Indemnitee of its election so to assume such defense, the
Corporation shall not be liable to the Indemnitee for any legal or other
expenses subsequently incurred by the Indemnitee in connection with such claim,
other than as provided below in this Section 4. The Indemnitee shall have the
right to employ his own counsel in connection with such claim, but the fees and
expenses of such counsel incurred after notice from the Corporation of its
assumption of the defense thereof shall be at the expense of the Indemnitee
unless (i) the employment of counsel by the Indemnitee has been authorized by
the Corporation, (ii) counsel to the Indemnitee shall have reasonably concluded
that there may be a conflict of interest or position on any significant issue
between the Corporation and the Indemnitee in the conduct of the defense of such
action or (iii) the Corporation shall not in fact have

                                      -9-
<PAGE>
 
employed counsel to assume the defense of such action, in each of which cases
the fees and expenses of counsel for the Indemnitee shall be at the expense of
the Corporation, except as otherwise expressly provided by this Article. The
Corporation shall not be entitled, without the consent of the Indemnitee, to
assume the defense of any claim brought by or in the right of the Corporation or
as to which counsel for the Indemnitee shall have reasonably made the conclusion
provided for in clause (ii) above.

     5.  Advance of Expenses. Subject to the provisions of Section 6 below, in
         ------------------- 
the event that the Corporation does not assume the defense pursuant to Section 4
of this Article of any action, suit, proceeding or investigation of which the
Corporation receives notice under this Article, any expenses (including
attorneys' fees) incurred by an Indemnitee in defending a civil or criminal
action, suit, proceeding or investigation or any appeal therefrom shall be paid
by the Corporation in advance of the final disposition of such matter; provided,
                                                                       --------
however, that the payment of such expenses incurred by an Indemnitee in advance
- - -------  
of the final disposition of such matter shall be made only upon receipt of an
undertaking by or on behalf of the Indemnitee to repay all amounts so advanced
in the event that it shall ultimately be determined that the Indemnitee is not
entitled to be indemnified by the Corporation as authorized in this Article.
Such undertaking shall be accepted without reference to the financial ability of
the Indemnitee to make such repayment.

     6.  Procedure for Indemnification. In order to obtain indemnification or
         -----------------------------
advancement of expenses pursuant to Section 1, 2, 3 or 5 of this Article, the
Indemnitee shall submit to the Corporation a written request, including in such
request such documentation and information as is reasonably available to the
Indemnitee and is reasonably necessary to determine whether and to what extent
the Indemnitee is entitled to indemnification or advancement of expenses. Any
such indemnification or advancement of expenses shall be made promptly, and in
any event within 60 days after receipt by the Corporation of the written request
of the Indemnitee, unless with respect to requests under Section 1, 2 or 5 the
Corporation determines within such 60-day period that the Indemnitee did not
meet the applicable standard of conduct set forth in Section 1 or 2, as the case
may be. Such determination shall be made in each instance by (a) a majority vote
of the directors of the Corporation consisting of persons who are not at that
time parties to the action, suit or proceeding in question ("disinterested
directors"), whether or not a quorum, (b) a majority vote of a quorum of the
outstanding shares of stock of

                                     -10-
<PAGE>
 
all classes entitled to vote for directors, voting as a single class, which
quorum shall consist of stockholders who are not at that time parties to the
action, suit or proceeding in question, (c) independent legal counsel (who may,
to the extent permitted by law, be regular legal counsel to the Corporation), or
(d) a court of competent jurisdiction.

     7.  Remedies. The right to indemnification or advances as granted by this
         --------
Article shall be enforceable by the Indemnitee in any court of competent
jurisdiction if the Corporation denies such request, in whole or in part, or if
no disposition thereof is made within the 60-day period referred to above in
Section 6. Unless otherwise required by law, the burden of proving that the
Indemnitee is not entitled to indemnification or advancement of expenses under
this Article shall be on the Corporation. Neither the failure of the Corporation
to have made a determination prior to the commencement of such action that
indemnification is proper in the circumstances because the Indemnitee has met
the applicable standard of conduct, nor an actual determination by the
Corporation pursuant to Section 6 that the Indemnitee has not met such
applicable standard of conduct, shall be a defense to the action or create a
presumption that the Indemnitee has not met the applicable standard of conduct.
The Indemnitee's expenses (including attorneys' fees) incurred in connection
with successfully establishing his right to indemnification, in whole or in
part, in any such proceeding shall also be indemnified by the Corporation.

     8.  Subsequent Amendment. No amendment, termination or repeal of this
         --------------------
Article or of the relevant provisions of the General Corporation Law of Delaware
or any other applicable laws shall affect or diminish in any way the rights of
any Indemnitee to indemnification under the provisions hereof with respect to
any action, suit, proceeding or investigation arising out of or relating to any
actions, transactions or facts occurring prior to the final adoption of such
amendment, termination or repeal.

     9.  Other Rights. The indemnification and advancement of expenses provided
         ------------
by this Article shall not be deemed exclusive of any other rights to which an
Indemnitee seeking indemnification or advancement of expenses may be entitled
under any law (common or statutory), agreement or vote of stockholders or
disinterested directors or otherwise, both as to action in his official capacity
and as to action in any other capacity while holding office for the Corporation,
and shall continue as to an Indemnitee who has ceased to be a director or
officer, and shall inure to the benefit

                                     -11-
<PAGE>
 
of the estate, heirs, executors and administrators of the Indemnitee. Nothing
contained in this Article shall be deemed to prohibit, and the Corporation is
specifically authorized to enter into, agreements with officers and directors
providing indemnification rights and procedures different from those set forth
in this Article. In addition, the Corporation may, to the extent authorized from
time to time by its Board of Directors, grant indemnification rights to other
employees or agents of the Corporation or other persons serving the Corporation
and such rights may be equivalent to, or greater or less than, those set forth
in this Article.

     10.  Partial Indemnification. If an Indemnitee is entitled under any
          -----------------------
provision of this Article to indemnification by the Corporation for some or a
portion of the expenses (including attorneys' fees), judgments, fines or amounts
paid in settlement actually and reasonably incurred by him or on his behalf in
connection with any action, suit, proceeding or investigation and any appeal
therefrom but not, however, for the total amount thereof, the Corporation shall
nevertheless indemnify the Indemnitee for the portion of such expenses
(including attorneys' fees), judgments, fines or amounts paid in settlement to
which the Indemnitee is entitled.

     11.  Insurance.  The Corporation may purchase and maintain insurance, at 
          ---------
its expense, to protect itself and any director, officer, employee or agent of
the Corporation or another corporation, partnership, joint venture, trust or
other enterprise (including any employee benefit plan) against any expense,
liability or loss incurred by him in any such capacity, or arising out of his
status as such, whether or not the Corporation would have the power to indemnify
such person against such expense, liability or loss under the General
Corporation Law of Delaware.

     12.  Merger or Consolidation.  If the Corporation is merged into or 
          -----------------------
consolidated with another corporation and the Corporation is not the surviving
corporation, the surviving corporation shall assume the obligations of the
Corporation under this Article with respect to any action, suit, proceeding or
investigation arising out of or relating to any actions, transactions or facts
occurring prior to the date of such merger or consolidation.

     13.  Savings Clause.  If this Article or any portion hereof shall be 
          --------------
invalidated on any ground by any court of competent jurisdiction, then the
Corporation shall nevertheless indemnify each Indemnitee as to any expenses
(including attorneys' fees),

                                     -12-
<PAGE>
 
judgments, fines and amounts paid in settlement in connection with any action,
suit, proceeding or investigation, whether civil, criminal or administrative,
including an action by or in the right of the Corporation, to the fullest extent
permitted by any applicable portion of this Article that shall not have been
invalidated and to the fullest extent permitted by applicable law.

     14.  Definitions.  Terms used herein and defined in Section 145(h) and 
          -----------
Section 145(i) of the General Corporation Law of Delaware shall have the
respective meanings assigned to such terms in such Section 145(h) and Section
145(i).

     15.  Subsequent Legislation.  If the General Corporation Law of Delaware 
          ----------------------
is amended after adoption of this Article to expand further the indemnification
permitted to Indemnitees, then the Corporation shall indemnify such persons to
the fullest extent permitted by the General Corporation Law of Delaware, as so
amended.

     NINTH.  The Corporation reserves the right to amend, alter, change or 
repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statute and this Certificate of
Incorporation, and all rights conferred upon stockholders herein are granted
subject to this reservation.

     IN WITNESS WHEREOF, this Amended and Restated Certificate of Incorporation
which restates, integrates and amends the provisions of the Certificate of
Incorporation of the Corporation, and which has been duly adopted in accordance
with the provisions of Sections 242 and 245 of the Delaware General Corporation
Law, has been signed by its President this __ day of _______, 1996.

         the meeting to be held as soon thereafter as convenient.  If no
         annual meeting is held in accordance with the foregoing

         meeting, and any action taken at that special meeting shall have
         the same effect as if it had been taken at the annual meeting, and
         in such case all references in these By-laws to the annual meeting
         of the stockholders shall be deemed to refer to such special
         meeting.

              1.3  Special Meetings.  Special meetings of stockholders may
                   ----------------

         entitled to vote at the meeting, arranged in alphabetical order,

         for a period of at least 10 days prior to the meeting, at a place

         any stockholder of any adjournment of less than 30 days if the
         time and place of the adjourned meeting are announced at the
         meeting at which adjournment is taken, unless after the
         adjournment a new record date is fixed for the adjourned meeting.
         At the adjourned meeting, the corporation may transact any
         business which might have been transacted at the original meeting.  

              1.8  Voting and Proxies.  Each stockholder shall have one

         or persons to vote or act for him by written proxy executed by the
         stockholder or his authorized agent and delivered to the Secretary
         of the corporation.  No such proxy shall be voted or acted upon

              1.9  Action at Meeting.  When a quorum is present at any

         stock entitled to vote as separate classes, then in the case of
         each such class, the holders of shares of stock of that class
         representing a majority of the votes cast on a matter) shall
         decide any matter to be voted upon by the stockholders at such
         meeting, except when a different vote is required by express
         provision of law, the Certificate of Incorporation or these
         By-Laws.  When a quorum is present at any meeting, any election by
         stockholders shall be determined by a plurality of the votes cast
         on the election.

              1.10 Action without Meeting.  Any action required or
                   ----------------------
         permitted to be taken at any annual or special meeting of
         stockholders of the corporation may be taken without a meeting,
         without prior notice and without a vote, if a consent in writing,
         setting forth the action so taken, is signed by the holders of
         outstanding stock having not less than the minimum number of votes
         that would be necessary to authorize or take such action at a
         meeting at which all shares entitled to vote on such action were
         present and voted.  Prompt notice of the taking of corporate
         action without a meeting by less than unanimous written consent
         shall be given to those stockholders who have not consented in
         writing.

         of Directors, who may exercise all of the powers of the
         corporation except as otherwise provided by law or the Certificate
         of Incorporation.  In the event of a vacancy in the Board of

         by law, may exercise the powers of the full Board until the
         vacancy is filled.

              2.2  Number; Election and Qualification.  The number of
                   ----------------------------------
         directors which shall constitute the whole Board of Directors
         shall be determined by resolution of the stockholders or the Board
         of Directors, but in no event shall be less than one.  The number
         of directors may be decreased at any time and from time to time
         either by the stockholders or by a majority of the directors then
         in office, but only to eliminate vacancies existing by reason of
         the death, resignation, removal or expiration of the term of one
         or more directors.  The directors shall be elected at the annual
         meeting of stockholders by such stockholders as have the right to
         vote on such election.  Directors need not be stockholders of the
         corporation.

              2.4  Tenure.  Each director shall hold office until the next
                   ------
         annual meeting and until his successor is elected and qualified,

              2.5  Vacancies.  Unless and until filled by the stockholders,
                   ---------
         any vacancy in the Board of Directors, however occurring,
         including a vacancy resulting from an enlargement of the Board,
         may be filled by vote of a majority of the directors then in
         office, although less than a quorum, or by a sole remaining
         director.  A director elected to fill a vacancy shall be elected
         for the unexpired term of his predecessor in office, and a
         director chosen to fill a position resulting from an increase in
         the number of directors shall hold office until the next annual
         meeting of stockholders and until his successor is elected and
         qualified, or until his earlier death, resignation or removal.

              2.6  Resignation.  Any director may resign by delivering his
                   -----------
         written resignation to the corporation at its principal office or

         determined from time to time by the Board of Directors; provided
         that any director who is absent when such a determination is made
         shall be given notice of the determination.  A regular meeting of
         the Board of Directors may be held without notice immediately
         after and at the same place as the annual meeting of stockholders.

         business or home address at least 48 hours in advance of the
         meeting, or (iii) by mailing written notice to his last known
         business or home address at least 72 hours in advance of the
         meeting.  A notice or waiver of notice of a meeting of the Board
         of Directors need not specify the purposes of the meeting.

              2.10 Meetings by Telephone Conference Calls.  Directors or

         participate in a meeting of the Board of Directors or such
         committee by means of conference telephone or similar
         communications equipment by means of which all persons
         participating in the meeting can hear each other, and
         participation by such means shall constitute presence in person at
         such meeting.

              2.11 Quorum.  A majority of the total number of the whole
                   ------
         Board of Directors shall constitute a quorum at all meetings of
         the Board of Directors.  In the event one or more of the directors
         shall be disqualified to vote at any meeting, then the required
         quorum shall be reduced by one for each such director so
         disqualified; provided, however, that in no case shall less than
         one-third (1/3) of the number so fixed constitute a quorum.  In
         the absence of a quorum at any such meeting, a majority of the
         directors present may adjourn the meeting from time to time
         without further notice other than announcement at the meeting,
         until a quorum shall be present.

              2.12 Action at Meeting.  At any meeting of the Board of
                   -----------------
         Directors at which a quorum is present, the vote of a majority of
         those present shall be sufficient to take any action, unless a
         different vote is specified by law, the Certificate of
         Incorporation or these By-Laws.

              2.13 Action by Consent.  Any action required or permitted to
                   -----------------
         be taken at any meeting of the Board of Directors or of any

         meeting, if all members of the Board or committee, as the case may
         be, consent to the action in writing, and the written consents are

         directors may be removed, with or without cause, by the holders of
         a majority of the shares then entitled to vote at an election of
         directors, except that the directors elected by the holders of a
         particular class or series of stock may be removed without cause
         only by vote of the holders of a majority of the outstanding
         shares of such class or series.  

              2.15 Committees.  The Board of Directors may, by resolution
                   ----------
         passed by a majority of the whole Board, designate one or more
         committees, each committee to consist of one or more of the
         directors of the corporation.  The Board may designate one or more
         directors as alternate members of any committee, who may replace
         any absent or disqualified member at any meeting of the committee.
         In the absence or disqualification of a member of a committee, the
         member or members of the committee present at any meeting and not
         disqualified from voting, whether or not he or they constitute a
         quorum, may unanimously appoint another member of the Board of
         Directors to act at the meeting in the place of any such absent or
         disqualified member.  Any such committee, to the extent provided
         in the resolution of the Board of Directors and subject to the
         provisions of the General Corporation Law of the State of
         Delaware, shall have and may exercise all the powers and authority
         of the Board of Directors in the management of the business and
         affairs of the corporation and may authorize the seal of the
         corporation to be affixed to all papers which may require it.
         Each such committee shall keep minutes and make such reports as
         the Board of Directors may from time to time request.  Except as
         the Board of Directors may otherwise determine, any committee may
         make rules for the conduct of its business, but unless otherwise
         provided by the directors or in such rules, its business shall be
         conducted as nearly as possible in the same manner as is provided
         in these By-laws for the Board of Directors.

         compensation for their services and such reimbursement for
         expenses of attendance at meetings as the Board of Directors may
         from time to time determine.  No such payment shall preclude any
         director from serving the corporation or any of its parent or
         subsidiary corporations in any other capacity and receiving
         compensation for such service.

         adjournment of the meeting; provided, however, that the Board of
         Directors may fix a new record date for the adjourned meeting.

Calgene II, Inc.
1920 Fifth Street
Davis, CA  95616

Ladies and Gentlemen:

     This opinion is furnished to you in connection with a Registration
Statement on Form S-4 (the "Registration Statement"), filed with the Securities
and Exchange Commission (the "Commission") under the Securities Act of 1933, as
amended, for the registration of 31,290,445 shares of Common Stock, $.001 par
value per share (the "Shares"), of Calgene II, Inc., a Delaware corporation (the
"Company"). The Shares are to be issued pursuant to the Agreement and Plan of
Reorganization, dated as of October 13, 1995 between Calgene, Inc., a Delaware
corporation, and Monsanto Company, a Delaware corporation (the "Reorganization
Agreement").

     We have acted as counsel for the Company in connection with the issuance by
the Company of the Shares. We have examined signed copies of the Registration
Statement and all exhibits thereto, all as filed with the Commission. We have
also examined and relied upon the originals or copies of minutes of meetings of
the stockholders and Board of Directors of the Company, stock record books of
the Company, the By-laws of the Company, the Certificate of Incorporation of the
Company and the Amended and Restated Certificate of Incorporation of the Company
to be filed with the Secretary of State of the State of Delaware upon
consummation of the Reorganization (as defined in the Reorganization Agreement).

     We have not made an independent review of the laws of any state or
jurisdiction other than the Commonwealth of Massachusetts and the United States,
and the General Corporation Law statute of the State of Delaware. Accordingly,
we express no opinion herein with respect to the laws of any state or
jurisdiction other than the Commonwealth of Massachusetts and the United States,
and the General Corporation Law statute of the State of Delaware.

     Based upon the foregoing, we are of the opinion that the Shares have been
duly authorized and that, when issued and
<PAGE>
 
Calgene II, Inc.

Page 2

delivered by the Company in accordance with the terms of the Reorganization
Agreement, they will be validly issued, fully paid and nonassessable.

     We hereby consent to the filing of this opinion as part of the Registration
Statement and to the use of our name therein and in the related Prospectus under
the caption "Legal Matters."

     It is understood that this opinion is to be used only in connection with
the issuance of the Shares while the Registration Statement is in effect.


                                       Very truly yours,

Attention:  President

     Re:  Proposed Merger among Calgene II, Inc.,
          Calgene Acquisition Corp. and Calgene, Inc.
          -------------------------------------------

Ladies and Gentlemen:

     This opinion is being delivered to you in connection with the Agreement and
Plan of Reorganization dated October 13, 1995, (the "Agreement"), by and between
Calgene, Inc., a Delaware corporation ("Calgene") and Monsanto Company, a
Delaware corporation ("Monsanto"). Pursuant to such Agreement, Calgene and
Monsanto will establish Calgene II, Inc., a Delaware corporation ("Newco").
Newco in turn will establish Calgene Acquisition Corp., a Delaware corporation
("Sub") as a wholly-owned subsidiary and Sub will thereafter merge (the
"Merger") with and into Calgene. Pursuant to the Merger, holders of shares
Calgene Common Stock will exchange such shares for an equal number of shares of
Newco Common Stock and holders of shares of Calgene Series A Preferred Stock
will exchange such shares for an equal number of shares of Newco Series A
Preferred Stock. Except as otherwise provided, capitalized terms not defined
herein shall have the meanings set forth in the Agreement or in the letters
delivered to Hale and Dorr by Calgene and Monsanto containing certain
representations of Calgene and Monsanto relevant to this opinion (the
"Representation Letters"). All section references, unless otherwise indicated,
are to the Internal Revenue Code of 1986, as amended (the "Code").

     In our capacity as counsel to Calgene in the Merger, and for purposes of
rendering this opinion, we have examined and relied upon the Agreement including
exhibits thereto, the Representation Letters, the Registration Statement of
Newco on Form S-4 dated February 6 (the "Registration Statement"), and such
other documents as we considered relevant to our analysis. We have assumed that
all parties to the Agreement (as well as Newco and
<PAGE>
 
Calgene, Inc.
February 6, 1996
Page 2




Sub) and to any other documents examined by us have acted, and will act, in
accordance with the terms of such Agreement or documents, and that the Merger
will be consummated at the Effective Time pursuant to the terms and conditions
set forth in the Agreement. Further, we have assumed that all representations
contained in the Agreement, as well as those representations contained in the
Representation Letters of even date herewith are true and complete in all
material respects as of the Effective Time. We have not attempted to verify
independently such representations, but in the course of our representation,
nothing has come to our attention which would cause us to question the accuracy
thereof.

     In our examination of documents, we have assumed the authenticity of
original documents, the accuracy of copies, and the genuineness of signatures.
We have also assumed that there is no plan or intention on the part of Calgene's
shareholders or of Monsanto to engage in a sale, exchange, or other disposition
of shares of Newco Common Stock or Newco Series A Preferred Stock to be received
in the Merger or in the Exchange (as the case may be) that would reduce the
number of shares of either (or both) the Newco Common Stock or Newco Series A
Preferred Stock held by them in the aggregate to a number of shares of such
class of stock that is less than 80% of the number of shares of such class
received in the Merger and the Exchange combined.

     The conclusions expressed herein represent our opinion as to the proper
treatment of certain aspects of the Merger under the income tax laws of the
United States based upon the Code, Treasury Regulations, case law, and rulings
and other pronouncements of the Internal Revenue Service (the "IRS") as in
effect on the date of this opinion. No assurances can be given that such laws
will not be amended or otherwise changed prior to the Effective Time of the
Merger, or at any other time, and that such changes will not affect the
conclusions expressed herein. Our opinion relates solely to the tax consequences
of the Merger under the federal laws of the United States, and we express no
opinion (and no opinion should be inferred) regarding the tax consequences of
the Merger under the laws of any other jurisdiction.

     Our opinions represent our best judgment as to how a court would decide if
presented with the issues addressed herein and are not binding upon either the
IRS or any court. Thus, no assurances can be given that a position taken in
reliance on our opinions will not be challenged by the IRS or rejected by a
court.

     On the basis of, and subject to the foregoing, and in reliance upon the
representations described above, we are of the opinion that:

     1.   No gain or loss for federal income tax purposes will be recognized by
Calgene, Newco or Sub upon consummation of the Merger.

     2.   A holder of Calgene Common Stock will recognize no gain or loss for
federal income tax purposes upon the exchange of such stockholder's Calgene
Common Stock for Newco Common Stock pursuant to the Merger.

     3.   The aggregate tax basis in the shares of Newco Common Stock received
by a holder of Calgene Common Stock in the Merger will equal such stockholder's
aggregate adjusted basis in the shares of Calgene Common Stock surrendered in
the Merger.

     4.   The holding period for the shares of Newco Common Stock received by a
holder of Calgene Common Stock in the Merger will include the holding period for
the shares of Calgene Common Stock surrendered by the stockholder in the Merger
provided that the shares of Calgene Common Stock were held as capital assets
prior to the Merger.

     The foregoing opinions may not be applicable to Calgene shareholders who
are subject to special treatment under the federal income tax laws (including,
for example, persons who acquired Calgene shares pursuant to the exercise of
employee stock options or otherwise as compensation).

     This opinion addresses only the specific tax opinions set forth above, and
does not address any other federal, state, local or foreign tax consequences
that may result from the Merger or any other transaction (including any
transaction undertaken in connection with the Merger). In particular, but not by
way of limitation, we express no opinion regarding (i) the tax consequences of
the conversion of outstanding options to acquire Calgene Common Stock into
options to acquire Newco Common Stock to the holders of such options and (ii)
the tax consequences of the Exchange. This opinion may not be relied upon except
with respect to the consequences specifically discussed herein.

                  CALGENE II, INC. CREDIT FACILITY AGREEMENT

     THIS AGREEMENT is made as of the _____ day of ____________, 1996, by and
between CALGENE II, INC., a Delaware corporation having its principal office in
Davis, California (the "Company"), and MONSANTO COMPANY, a Delaware corporation
with its main offices at 800 N. Lindbergh Boulevard, St. Louis, Missouri 63167
("Monsanto").

     In consideration of the mutual benefits accruing to each of the parties,
the receipt and sufficiency of which are hereby acknowledged, and in further
consideration of the mutual performance of this Agreement, the parties hereto
agree as follows:

                                   ARTICLE I
                         AMOUNT AND TERMS OF THE LOANS

     Section 1.01.  Loans.  During the Commitment Period (hereinafter defined),
                    -----                                                      
Monsanto agrees, on the terms and conditions hereafter set forth, to make three
(3) one (1) year loans, totalling not more than $45,000,000, to the Company for
general corporate purposes from time to time after the date hereof, not to
exceed at any time outstanding Fifteen Million Dollars ($15,000,000), said sum
being the "Commitment." Within said limits and prior to the occurrence of an
Event of Default (hereinafter defined), the Company may borrow, repay and
reborrow under this Agreement, each such borrowing or reborrowing being referred
to herein as an "Advance." Each Advance shall be in an amount of not less than
One Hundred Thousand Dollars ($100,000) and shall be in increments of One
Hundred Thousand Dollars ($100,000). Each request for an Advance shall be made
in writing substantially in the form attached hereto as Exhibit A and
                                                        ---------    
incorporated herein or on such other forms acceptable to Monsanto or in any
other manner acceptable to Monsanto.  Monsanto shall process each request for an
Advance as soon as reasonably practicable but no later than ten (10) working
days after receipt of the Company's request. Each of the Loans (hereinafter
defined) shall consist of no more than twelve (12) Advances. Upon fulfillment of
<PAGE>
 
the applicable conditions set forth in Article II hereof and subject to the
provisions of this Agreement, Monsanto shall make such Advances available to the
Company by wire transfer or otherwise as reasonably directed by the Company, but
the Company agrees to reimburse Monsanto for all such wire and other transfer
costs incurred by Monsanto, and the Company shall bear all risks of delays or
nondelivery or misdelivery of any such funds so wired or otherwise transferred
other than those caused by Monsanto's negligence or failure to transfer such
funds in accordance with the Company's directions. Any Advance under this
Agreement shall be deemed made on the day that the Advance proceeds are wired or
otherwise transferred or, if the Advance proceeds are used to repay an
outstanding Loan, on the day such proceeds are so applied. All Advances made on
or after the date of this Agreement and before the first anniversary of this
Agreement shall be considered to be part of "Loan One"; all Advances made on or
after the first anniversary of this Agreement and before the second anniversary
of this Agreement shall be considered to be part of "Loan Two"; all Advances
made on or after the second anniversary of this Agreement and before the earlier
of the third anniversary of this Agreement and September 30, 1998, shall be
considered to be part of "Loan Three." Loan One, Loan Two and Loan Three shall
hereinafter be collectively referred to as the "Loans" and individually as a
"Loan." The "Commitment Period" means the period from the date of this Agreement
to the earlier of September 30, 1998, or the third anniversary of the execution
of this Agreement or the date Monsanto terminates its obligations to make
further Advances or Loans hereunder pursuant to Section 5.02 hereof. The Loans
made pursuant to this Agreement shall be supported by the joint and several
guaranty (the "Guaranty") of the subsidiaries of the Company which are listed on
Exhibit B hereto (the "Subsidiaries" or a "Subsidiary") in the form attached
- - ---------                                                                   
hereto as Exhibit C.
          --------- 

     Section 1.02.  Notes.  Each of the Loans shall be evidenced by a promissory
                    -----                                                       
note in the form of Exhibit D attached hereto (a "Note"), payable to the order
                    ---------                                                 
of Monsanto and representing the obligation of the Company to pay the amount of
the aggregate unpaid principal amount of such Loans made by Monsanto, together
with interest on the principal amount outstanding from time to time, as provided
in this Agreement. Each Note shall provide that the Company shall pay all
outstanding principal and accrued interest to Monsanto on the first anniversary
of the date of such Note or, in the case of the Note

                                      -2-
<PAGE>
 
evidencing Loan Three, on the earlier of September 30, 1998, or the first
anniversary of the date of such Note; provided, however, that the Company shall
have the option to convert the outstanding principal and accrued interest into
shares of the Company's common stock as provided in Section 1.06 hereof, subject
to Monsanto's right to require the Company to sell shares and pay cash (as
provided in such Section 1.06). The Notes evidencing Loan One, Loan Two and Loan
Three shall be dated as of the date of this Agreement, as of the first
anniversary of this Agreement and as of the second anniversary of this
Agreement, respectively.

     Section 1.03.  Interest Rate.  The outstanding principal balance of the
                    -------------                                           
Loans from time to time shall bear interest at two percent (2%) above Citibank's
published prime rate ("Note Rate"). Interest shall be compounded daily and
adjusted quarterly on each January 1, April 1, July 1 and October 1 pursuant to
calculations performed by Monsanto.

     Section 1.04.  Effects of Event of Default or Potential Default.
                    ------------------------------------------------  
Notwithstanding the foregoing and in addition to the remedies set forth in
Sections 5.02 and 5.03 hereof, upon an Event of Default and so long as such
Event of Default shall continue or, if Monsanto shall have accelerated the
maturity date of the then outstanding Loans pursuant to Section 5.02 hereof,
until the Loans are repaid in full, the principal amount of all Loans then
outstanding, together with all interest then accrued, shall thereafter bear
interest at the Default Rate (hereinafter defined), with interest payable upon
demand. The "Default Rate" shall be the per annum rate equal to three percent
(3%) above the Note Rate that would otherwise be applicable and thereafter until
paid in full. During the continuance of an Event of Default, the Company shall
have no right to obtain any new Advances under this Agreement.

     A "Potential Default" shall be an event which, solely but for the lapse of
time or the giving of notice, or both, would constitute an Event of Default. If
a Potential Default then exists and has not been waived in writing by Monsanto
and does not itself constitute or is not declared an Event of Default, the
Company shall have no right to borrow any additional money beyond the principal
amount of Loans then outstanding.

     Section 1.05.  Miscellaneous Provisions Regarding Loan Payments and
                    ----------------------------------------------------
Interest.  All payments on any Loan shall be made to Monsanto by wire transfer
- - --------                                                                      
for deposit in Citibank, New York, New York, Account #00000502 unless Monsanto
notifies Company of a different place for payments to be made. Loan One shall be
due and payable on the first anniversary of the Note evidencing Loan One or such
earlier date as all of the outstanding Loans have been declared due and payable
pursuant to Section 5.02 hereof. Loan Two shall be due and payable on the first
anniversary of the Note evidencing Loan Two or such earlier date as all of the
outstanding Loans have been declared due and payable pursuant to Section 5.02
hereof. Loan Three shall be due and payable on the earlier of September 30,
1998, or the first anniversary of the Note evidencing Loan Three or such earlier
date as all of the outstanding Loans have been declared due and payable pursuant
to Section 5.02 hereof. The date each Loan shall be due and payable shall
hereafter from time to time be referred to as the "Maturity Date" and,
collectively, as the "Maturity Dates." If Monsanto makes a new Loan hereunder on
a day on which the Company is required to or has elected to repay all or any
part of an outstanding Loan and the Company has not elected to exercise its
conversion rights under Section 1.06 hereof, Monsanto shall apply the proceeds
of this new Loan to make such repayment, and only an amount equal to the
difference (if any) between the amount being borrowed and the amount being
repaid shall be made available by Monsanto to the Company, as provided in
Section 1.01 hereof. All interest rates respecting any Loan hereunder are stated
on a per annum basis with a year of three hundred and sixty (360) days, and
interest is calculated on the actual number of days elapsed (including the first
day, but excluding the last day of any period for any Loan under this
Agreement). All Loans outstanding after their respective Maturity Dates or such
earlier date as all of the outstanding Loans have been declared due pursuant to
Section 5.02 hereof shall thereafter bear interest at the Default Rate on all
unpaid amounts until the Loans are fully paid.

     Section 1.06   Right of Conversion in Lieu of Repayment.  In lieu of
                    ----------------------------------------             
repayment in cash of outstanding principal and accrued interest on each Maturity
Date, the Company, subject to Monsanto's right to require the Company to sell
shares and pay cash, as provided below, may elect to convert all or any portion
of the principal and accrued interest due under the applicable Loan into shares
of common stock of the Company at the average of the

                                      -4-
<PAGE>
 
closing market prices for such shares during the thirty (30) trading days
immediately preceding the Maturity Date for such Loan (the "Average Market
Price").  In order to exercise its conversion rights, at least thirty (30) days
prior to the Maturity Date for a Loan, the Company shall send a written notice
(the "Conversion Notice") to Monsanto, stating that the Company intends to
exercise such conversion rights.  The Conversion Notice shall specify the amount
of the principal and accrued interest that the Company intends to convert (the
"Conversion Amount").

     Monsanto may, in its sole discretion and within five (5) business days
after its receipt of any Conversion Notice from the Company, give written notice
(the "Alternative Notice") to the Company, stating that all or any part of the
Conversion Amount set forth in such Conversion Notice (the "Alternative
Conversion Amount") shall be payable in cash.  Upon receipt of an Alternative
Notice, (i) the Alternative Conversion Amount may no longer be converted into
shares of common stock of the Company (unless the Alternative Notice shall have
been withdrawn as provided below) and (ii) the difference, if any, between the
Conversion Amount and the Alternative Conversion Amount shall be converted into
shares of common stock of the Company in accordance with the terms of the
Conversion Notice and the applicable provisions of this Section 1.06.  The
Company shall proceed promptly, using its best efforts and at its expense, to
take such actions as are necessary to effect the public sale of a number of
shares of its common stock (rounded to the next lowest full share) equal to the
Alternative Conversion Amount divided by the Average Market Price (the
"Offering").  The Alternative Conversion Amount shall be due and payable to
Monsanto in cash on the closing date for the Offering.  On such closing date,
the net proceeds of such Offering shall be paid by the Company to Monsanto in
full payment and satisfaction of such Alternative Conversion Amount, even if
such net proceeds are less than or greater than such Alternative Conversion
Amount.

     If the Offering has not closed within sixty (60) days after the Company's
receipt of an Alternative Notice, Monsanto may, thereafter and in its sole
discretion, withdraw its Alternative Notice at any time.  If Monsanto withdraws
an Alternative Notice, then, within five (5) business days thereafter, the
Company shall issue to Monsanto a number of shares of

                                      -5-
<PAGE>
 
common stock of the Company (rounded to the next lowest full share) equal to the
Alternative Conversion Amount divided by the Average Market Price.

     If (i) the Company properly notifies Monsanto as provided above in this
Section 1.06 and (ii) Monsanto does not give an Alternative Notice for the full
Conversion Amount, then, within five (5) business days after the Maturity Date
for a Loan, the Company shall issue to Monsanto a number of shares of common
stock of the Company (rounded to the next lowest full share) equal to the
Conversion Amount (or the difference between the Conversion Amount and
Alternative Conversion Amount, as applicable) divided by the Average Market
Price.

     Any portion of the Conversion Amount not converted as provided above (i.e.,
because such amount would require conversion into a fractional share) shall be
paid to Monsanto by wire transfer as set forth above.  Upon any such conversion,
the amount converted shall first be applied to reduce the accrued interest due
on the Loan as of the Maturity Date, and any remaining portion of the amount
converted shall be applied to reduce the principal due on such Loan.

shares issued pursuant to Section 5.03 hereof) to Monsanto, it shall deliver to
Monsanto an opinion from counsel to the Company in a form reasonably
satisfactory to Monsanto relating to the issuance of such shares.

     Notwithstanding anything to the contrary contained in this Agreement, on
each Maturity Date, all outstanding principal and accrued interest not to be
repaid, or converted by the Company to shares of common stock of the Company, in
accordance with this Section 1.06 shall be repaid in full to Monsanto in
accordance with Section 1.05 hereof.

     Section 5.02.  Rights of Monsanto.  Upon the occurrence of an Event of

     Section 5.03.  Default Conversion.  Upon the occurrence and during the
                    ------------------                                     
continuation of an Event of Default, for a period of thirty (30) days from the
occurrence of the Event of Default (the "Election Period"), the Company, subject
to Monsanto's right to require the Company to sell shares and pay cash, as
provided below, may elect to convert all or any portion of the principal and
accrued interest under any outstanding Loan into shares of common stock of the
Company at the average of the closing market prices for such shares during the
thirty (30) trading days immediately preceding the Default Conversion Date

                                      -24-
<PAGE>
 
(hereinafter defined) for such Loan (the "Default Average Market Price").
Monsanto shall not take any of the actions set forth in paragraphs (b) or (c) of
Section 5.02 hereof until the end of such Election Period.  If all of the
principal and accrued interest are converted into shares of common stock of the
Company or paid in cash pursuant to this Section 5.03, Monsanto shall have no
further rights under Section 5.02 hereof, arising because of the Event of
Default for which such conversion or payment was made hereunder.

     If the Company does not elect to convert all of the principal and accrued
interest under any outstanding Loan into shares of common stock of the Company
during the Election Period, then, within ten (10) days after such Election
Period, Monsanto may, in addition to any other remedies set forth in this
Agreement, elect to convert all or any portion of the remaining principal and
accrued interest under such Loan into shares of common stock of the Company at
the Default Average Market Price; provided, however, that in no event shall
Monsanto elect to convert principal and accrued interest into more than three
million (3,000,000) shares of common stock of the Company (as such number is
adjusted for stock dividends, stock splits and similar events affecting holders
of the Company's common stock) for each Loan.

     In order to exercise the conversion rights described above, at any time
after the occurrence and during the continuation of an Event of Default, a party
shall send a written notice (the "Default Conversion Notice") to the other
party, stating that the exercising party intends to exercise such conversion
rights; provided, however, that, in the case of the Company, the Default
Conversion Notice may only be given during the Election Period.  The Default
Conversion Notice shall specify (i) the amount of the principal and accrued
interest that the exercising party intends to convert (the "Default Conversion
Amount") and (ii) the date as of which such conversion shall take place (the
"Default Conversion Date"), which date shall not be later than ten (10) days
after the date of the Default Conversion Notice.

     Monsanto may, in its sole discretion and within five (5) business days
after its receipt of any Default Conversion Notice from the Company, give
written notice (the "Alternative

                                      -25-
<PAGE>
 
Default Notice") to the Company, stating that all or any part of the Default
Conversion Amount set forth in such Default Conversion Notice (the "Alternative
Default Conversion Amount") shall be payable in cash.  Upon receipt of an
Alternative Default Notice, (i) the Alternative Default Conversion Amount may no
longer be converted into shares of common stock of the Company (unless the
Alternative Default Notice shall have been withdrawn as provided below) and (ii)
the difference, if any, between the Default Conversion Amount and the
Alternative Default Conversion Amount shall be converted into shares of common
stock of the Company in accordance with the terms of the Default Conversion
Notice and the applicable provisions of this Section 5.03.  The Company shall
proceed promptly, using its best efforts and at its expense, to take such
actions as are necessary to effect the public sale of a number of shares of its
common stock (rounded to the next lowest full share) equal to the Alternative
Default Conversion Amount divided by the Default Average Market Price (the
"Default Offering").  The Alternative Default Conversion Amount shall be due and
payable to Monsanto in cash on the closing date for the Default Offering.  On
such closing date, the net proceeds of such Default Offering shall be paid by
the Company to Monsanto in full payment and satisfaction of such Alternative
Default Conversion Amount, even if such net proceeds are less than or greater
than such Alternative Default Conversion Amount.

     If the Default Offering has not closed within sixty (60) days after the
Company's receipt of an Alternative Default Notice, Monsanto may, thereafter and
in its sole discretion, withdraw its Alternative Default Notice at any time.  If
Monsanto withdraws an Alternative Default Notice, then, within five (5) business
days thereafter, the Company shall issue to Monsanto a number of shares of
common stock of the Company (rounded to the next lowest full share) equal to the
Alternative Default Conversion Amount divided by the Default Average Market
Price.

     If (i) either party properly gives the other party a Default Conversion
Notice and (ii) in the case of a Default Conversion Notice given by the Company,
Monsanto does not give an Alternative Default Notice for the full Default
Conversion Amount, then, within five (5) business days after the Default
Conversion Date, the Company shall issue to Monsanto a number of shares of
common stock of the Company (rounded to the next lowest full share)

                                      -26-
<PAGE>
 
equal to the Default Conversion Amount (or the difference between the Default
Conversion Amount and the Alternative Default Conversion Amount, as applicable)
divided by the Default Average Market Price.

     Any portion of the Default Conversion Amount not so converted (i.e.,
because such amount would require conversion into a fractional share or, in the
case of Monsanto, because the number of shares available are not adequate to
convert all of the Default Conversion Amount) shall be paid to Monsanto in cash.
Upon any such conversion, the Default Conversion Amount (including any portion
thereof paid to Monsanto in cash) shall first be applied to reduce the accrued
interest due on the Loan as of the Default Conversion Date, and any remaining
portion of the Default Conversion Amount shall be applied to reduce the
principal due on such Loan.

     Section 5.04.  Company's Obligations.  The Company recognizes that, if the
                    ---------------------                                      
Company fails to perform, observe or discharge any of its obligations under this
Agreement or the other collateral agreements hereto, a remedy at law may not
provide adequate relief to Monsanto; therefore, the Company agrees that Monsanto
shall be entitled to seek temporary and permanent injunctive relief in any such
case without the necessity of proving actual damages. All of Monsanto's rights
and remedies granted under this Agreement and the collateral agreements hereto
are cumulative and nonexclusive. The Company shall pay upon demand all costs and
expenses, including, without limitation, reasonable attorneys' fees and
expenses, incurred by Monsanto in enforcing this Agreement. All such sums not
paid on demand shall be treated as outstanding principal under the Notes.

continuance of any Event of Default, Monsanto is hereby authorized at any time
and from time to time, without notice to the Company (any such notice being
expressly waived by the Company), to set off and apply any and all funds at any
time held and other indebtedness at any time owing

                                      -27-

by Monsanto to or for the credit or the account of the Company or any of the
Subsidiaries against any and all of the obligations of the Company now or
hereafter existing under this Agreement and the Notes, irrespective of whether
or not Monsanto shall have made any demand under this Agreement or the Notes and
although such obligations may be unmatured. Notwithstanding the preceding
sentence, Monsanto shall not apply any of such setoff amounts until the end of
the notice periods set forth in Section 5.03 hereof. The rights of Monsanto
under this Section 6.01 are in addition to other rights and remedies (including,
without limitation, other rights of setoff) which Monsanto may have.

          (a)  All of the obligations of the Company to Monsanto under this
Agreement and the Notes, including, without limitation, the Company's obligation
to repay any Advances (collectively, the "Subordinated Indebtedness"), shall to
the extent and in the manner hereinafter set forth, be subordinated and subject
in right of payment to the prior payment in full of a Senior Indebtedness.
"Senior Indebtedness" means (a) all indebtedness of the Company, including the
principal of and interest on such indebtedness, whether outstanding on the date
of this Agreement or thereafter created (i) arising under working capital lines
of credit secured by inventory and/or receivables, (ii) incurred to acquire
property, plant or equipment and secured by the acquired asset or (iii)
otherwise permitted under Section 4.02(l) hereof at the time such indebtedness
is incurred, and (b) any modifications, refundings, deferrals, renewals or
extensions of any such Senior Indebtedness, or securities, notes or other
evidences of indebtedness issued in exchange for such Senior Indebtedness;
provided, however, that in no event shall the obligations of the Company under
the Gargiulo Credit Facility Agreement constitute Senior Indebtedness under this
Agreement.  No payment on account of principal or interest on the Subordinated
Indebtedness shall be made if, at the time of such payment or immediately after
giving the effect thereto, (i) there shall exist a default in any payment with
respect to any Senior Indebtedness or (ii) there shall have occurred an event of
default (other than a default in the payment of amounts due

                                      -28-

thereon) with respect to any Senior Indebtedness, as defined in the instrument
under which the same is outstanding, permitting the holders thereof to
accelerate the maturity thereof, and such event of default shall not have been
cured or waived or shall not have ceased to exist.  Notwithstanding the
foregoing or any other provision of this Section 7.01, nothing in this Section
7.01 shall restrict or otherwise limit Monsanto's or Company's rights under
Sections 1.06 or 5.03 hereof.

          (b)  In the event of any distribution, dividend, or application,
partial or complete, voluntary or involuntary, by operation or law or otherwise,
of all or any part of the assets of the Company or of the proceeds thereof to
the creditors of the Company or upon any indebtedness of the Company, occurring
by reason of the liquidation, dissolution, or other winding up of the Company,
or by reason of any execution sale, or bankruptcy, receivership, reorganization,
arrangement, insolvency, liquidation or foreclosure proceeding of or for the
Company or involving its property, no dividend, distribution or application
shall be made, and Monsanto shall not be entitled to receive or retain any
dividend, distribution, or application on or in respect of principal of or
interest on Subordinated Indebtedness, unless and until all principal of and any
interest on Senior Indebtedness then outstanding shall have been paid and
satisfied in full, and in any such event any dividend, distribution or
application otherwise payable in respect of Subordinated Indebtedness shall be
paid and applied on Senior Indebtedness until such Senior Indebtedness has been
fully paid and satisfied.

          (c)  The holders of Senior Indebtedness need not at any time give
Monsanto notice of any kind of the creation or existence of any Senior
Indebtedness, nor of the amount or terms thereof, all such notice being hereby
expressly waived.  Also, the holders of Senior Indebtedness may at any time and
from time to time, without the consent of or notice to Monsanto, without
incurring responsibility to Monsanto, and without impairing or releasing the
obligation of Monsanto under this Agreement (i) renew, refund or extend the
maturity of any Senior Indebtedness, or any part thereof, or otherwise revise,
amend or alter the terms and conditions thereof, (ii) sell, exchange, release or
otherwise deal with any property by whomsoever at any time pledged, mortgaged or
otherwise hypothecated or subjected to a lien

                                      -29-
<PAGE>
 
to secure any Senior Indebtedness, and (iii) exercise or refrain from exercising
any rights against the Company and others, including Monsanto.

          (d)  Monsanto shall not sell, assign or otherwise transfer any
Subordinated Indebtedness, or any part thereof, except (i) upon the agreement of
the transferee or assignee to abide by and be bound by the terms hereof and (ii)
when Monsanto may assign its rights under the Stockholders Agreement dated of
even date herewith between Company and Monsanto.

          (e)  Monsanto shall cause all Subordinated Indebtedness to be at all
times evidenced by the Notes of the Company and shall cause all such Notes to
bear thereon a legend substantially as follows:

               "The indebtedness evidenced by this Note is subordinate to any
               and all indebtedness, obligations and liabilities of the maker
               hereof to the holders of Senior Indebtedness in the manner and to
               the extent set forth in the Credit Facility Agreement (as defined
               below) to which reference is hereby made for a more full
               statement thereof."

          (f)  If, notwithstanding the provisions of this Agreement, Monsanto
shall receive any payment of principal or interest on Subordinated Indebtedness
which the Company is not entitled to make pursuant to the terms hereof, whether
or not Monsanto has knowledge that the Company is not entitled to make such
payment, Monsanto shall promptly account for such payment and upon the demand of
the holders of Senior Indebtedness pay over such payment to such holders for
application to the Senior Indebtedness owing to such holders.  No payment or any
distribution received by the holders of the Senior Indebtedness in respect of
Subordinated Indebtedness pursuant to any of the terms hereof shall entitle
Monsanto to any right, whether by virtue of subrogation or otherwise, in and to
any Senior Indebtedness unless and until all Senior Indebtedness has been fully
paid and satisfied and any commitment of the holders of Senior Indebtedness to
extend Senior Indebtedness to the Company has terminated.

such prior advances and accrued interest shall be deemed, without any action, to

submitted to Monsanto by Tomato Associates and the Company that is reasonably
acceptable to Monsanto, verifying that Tomato Associates has reached certain
milestones and achieved certain goals as set forth on Exhibit A attached hereto

Monsanto. The maximum amount of each Advance shall be determined in accordance
with the schedule set forth on Exhibit A. At no time shall Monsanto be obligated
                               ---------

forth on Exhibit A until such time as Tomato Associates and the Company have
         ---------

verifying Tomato Associates' achievement of the goal and milestone for which
Tomato Associates and the Company are seeking the Advance. Upon achievement of
the applicable goal and milestone and upon fulfillment of the applicable
conditions set forth in Article II hereof and subject to the provisions of this
Agreement, Monsanto shall make such Advances available by wire transfer directly
into Tomato Associates' bank account pursuant to wiring instructions to be
provided at the time the request for each Advance is submitted, but the Company
agrees to reimburse Monsanto for all wire and other transfer costs incurred by
Monsanto, and the Company shall bear all risks of delays or nondelivery or
misdelivery of any such funds so wired or otherwise transferred other than those
caused by Monsanto's negligence or failure to transfer such funds in accordance
with the Company's directions. Any Advance under this Agreement shall be deemed
made on the day that the Advance proceeds are wired or otherwise transferred or,

Advance as soon as reasonably practicable but no later than ten (10) working
days after receipt of the Company's request.  The "Commitment Period" means the

     Section 1.02.  Note.  The Loan shall be evidenced by a promissory note in
                    ----                                                      
the form of Exhibit E attached hereto (the "Note"), dated as of the date hereof,

     from the following events during such Fiscal Year, in all cases as included
     in calculating such Operating Income, as reflected in Tomato Associates'
     consolidated statement of operations for such Fiscal Year:

          -  the disposition of assets outside the ordinary course of business;
          -  the retirement of assets; and
          -  write-down of assets.

          (iii)  the addition of the aggregate net amount of any decrease, and
     subtraction of the aggregate net amount of any increase, in current assets
     (excluding cash, cash equivalents and short-term investments) which
     include, but are not limited to, the following items as included in Tomato
     Associates' consolidated balance sheet at the end of such Fiscal Year as

          Amounts due to growers;
          Deferred compensation;
          Deferred income taxes; and
          Liability reserves;

     Fiscal Year, as included in Tomato Associates' consolidated statement of
     cash flows for such Fiscal Year;

     consistently applied, and audited by Tomato Associates' independent
     certified public accountants; and

          (vii)  the addition of the aggregate net amount of any increase, and
     subtraction of the aggregate net amount of any decrease, in noncurrent
     liabilities as reflected in Tomato Associates' consolidated balance sheet
     at the end of such Fiscal Year compared to the corresponding items included

     next preceding Fiscal Year. For purposes of this calculation, changes in

     hereof or amounts due Monsanto hereunder shall be excluded from noncurrent
     liabilities.

     "Fiscal Year" shall mean the period commencing with July 1 and ending with

<PAGE>
 
reflected in the consolidated statement of operations of Tomato Associates and
its consolidated subsidiaries for such Fiscal Year prepared in accordance with
generally accepted accounting principles, consistently applied, and audited by
Tomato Associates' independent certified public accountants.  Notwithstanding
the provisions of the preceding sentence, the initial Fiscal Year under this
Agreement shall be the period commencing on the first day of the fiscal quarter
beginning after the date hereof and ending with the following June 30.

     "Cumulative Free Cash Flow" shall mean the aggregate of the Free Cash Flow
of Tomato Associates during the period between the execution date of this
Agreement and the Maturity Date, during the period between the Maturity Date and
the Extended Maturity Date (hereinafter defined) and during the period between
the Extended Maturity Date and the Final Maturity Date (hereinafter defined),
respectively.  At the end of each Fiscal Year, the Chief Financial Officer of
the Company shall certify the amount of Tomato Associates' Free Cash Flow for
the Fiscal Year just ended.

     "Repayment Portion" shall mean the sum of (i) 20% of the first $10 million
of Cumulative Free Cash Flow or portion thereof, (ii) 50% of the next $10
million of Cumulative Free Cash Flow or portion thereof and (iii) 80% of the
remaining balance of Cumulative Free Cash Flow, if any.

     All transactions between Tomato Associates and any affiliate of Tomato
Associates during the term of this Agreement shall be accounted for on an arm's-
length basis.  Further, (i) dividends and returns of capital by Tomato
Associates to Company, (ii) investments by Company in Tomato Associates and
(iii) any loans between Tomato Associates and Company (or any direct or indirect
subsidiary of Company that is not a direct or indirect subsidiary of Tomato
Associates) shall not be considered when determining "Free Cash Flow."

     If the Repayment Portion of Cumulative Free Cash Flow is not sufficient to
pay all the then outstanding principal and accrued interest on the Maturity
Date, then the Company shall pay to Monsanto on the Maturity Date the Repayment
Portion of the Cumulative Free

                                      -6-
<PAGE>
 
Cash Flow, the Maturity Date as to the principal and accrued interest remaining
outstanding after such payment is applied, if any, shall be extended to the
sixth anniversary of this Agreement ("Extended Maturity Date").  If the
Repayment Portion of the Cumulative Free Cash Flow (less the aggregate amount of
principal and accrued interest previously paid) is not sufficient to pay all the
then outstanding principal and accrued interest on the Extended Maturity Date,
then the Company shall pay to Monsanto on the Extended Maturity Date the
Repayment Portion of the Cumulative Free Cash Flow, and the Extended Maturity
Date as to the principal and accrued interest remaining outstanding after such
payment is applied, if any, shall be extended to the eighth anniversary of this
Agreement ("Final Maturity Date").  If the Repayment Portion of the Cumulative
Free Cash Flow (less the aggregate amount of principal and accrued interest
previously paid) is not sufficient to pay all the then outstanding principal and
accrued interest on the Final Maturity Date, then (i) the Company shall pay to
Monsanto on the Final Maturity Date the Repayment Portion of the Cumulative Free
Cash Flow and (ii) Monsanto, at its sole option, may do any one or combination
of the following:  (A) convert all or any remaining portion of the then
outstanding principal and accrued interest to the Company's common stock in
compliance with the terms of Section 1.06 hereof, (B) further extend the Final
Maturity Date on the same terms and conditions as are contained in this
Agreement or (C) elect, in its sole discretion, to require the Company to sell
publicly, at the Company's expense, such number of shares of its common stock as
is equal to that portion of such remaining portion of the then outstanding
principal and accrued interest for which Monsanto has not made an election to
convert under clause (A) above and/or to extend the Final Maturity Date under
clause (B) above ("Election Amount"), whereupon the Company shall proceed
promptly to use its best efforts to take such actions as are necessary to effect
a sale of such shares of its common stock, the net proceeds of which shall be
paid to Monsanto in full payment and satisfaction of the Election Amount.  If
the Company has not so sold such shares within sixty (60) days after its receipt
of notice of Monsanto's election under clause (C) above, then, at any time
thereafter, Monsanto may, in its sole discretion, withdraw any such election,
whereupon the rights and obligations of the parties hereto shall be restored.

     Section 1.03.  Interest Rate.  The outstanding principal balance of the
                    -------------                                           
Loan from time to time shall bear interest at two percent (2%) above Citibank's
published prime rate ("Note Rate").  Interest shall be compounded daily and
adjusted quarterly on each January 1, April 1, July 1 and October 1 pursuant to
calculations performed by Monsanto.

     Section 1.04.  Effects of Event of Default or Potential Default.
                    ------------------------------------------------  
Notwithstanding the foregoing and in addition to the remedies set forth in
Sections 5.02 and 5.03 hereof, upon an Event of Default and so long as such
Event of Default shall continue, the principal amount of the Loan then
outstanding, together with all interest then accrued, shall thereafter bear
interest at the Default Rate (hereinafter defined), with interest payable upon
demand. The "Default Rate" shall be the per annum rate equal to three percent
(3%) above the Note Rate that would otherwise be applicable and thereafter until
paid in full. During the continuance of an Event of Default, the Company shall
have no right to obtain any new Advances under this Agreement.

     A "Potential Default" shall be an event which, solely but for the lapse of
time or the giving of notice, or both, would constitute an Event of Default. If
a Potential Default then exists and has not been waived in writing by Monsanto
and does not itself constitute or is not declared an Event of Default, the
Company shall have no right to borrow any additional money beyond the principal
amount of the Loan then outstanding.

     Section 1.05.  Miscellaneous Provisions Regarding Loan Payments and
                    ----------------------------------------------------
Interest.  All payments on the Loan shall be made to Monsanto by wire transfer

for deposit in Citibank, New York, New York, Account #00000502 unless Monsanto
notifies the Company of a different place for payments to be made. All interest
rates respecting the Loan hereunder are stated on a per annum basis with a year
of three hundred and sixty (360 days), and interest is calculated on the actual
number of days elapsed (including the first day, but excluding the last day of
any period for the Loan).  Any outstanding principal and accrued interest that
has been declared due pursuant to Section 5.02 hereof shall thereafter bear
interest at the Default Rate on all unpaid amounts until such amounts are fully
paid.

     Section 1.06  Right of Conversion in Lieu of Repayment.  In addition to any
                   ----------------------------------------                     
other remedies that Monsanto may have, in lieu of repayment of outstanding
principal and accrued interest on and after the Final Maturity Date, Monsanto
may elect, at any time after the Final Maturity Date, to convert all or any
portion of the principal and accrued interest due under the Loan into shares of
common stock of the Company at the average of the closing market prices for such
shares during the thirty (30) trading days immediately preceding the Conversion
Date (as hereafter defined) for such Loan. In order to exercise its conversion
rights, at any time on or after the Final Maturity Date, Monsanto may send a
written notice (the "Conversion Notice") to the Company that Monsanto intends to
exercise such conversion rights and the date as of which such conversion shall
take place (the "Conversion Date"). The Conversion Notice shall specify the
amount of the principal and accrued interest that Monsanto intends to convert
(the "Conversion Amount"). If Monsanto properly notifies the Company as provided
in the preceding sentences, then within five (5) business days after the

"Conversion Shares") of common stock of the Company (rounded to the next lowest
full share) equal to the Conversion Amount divided by the average of the closing
market prices for such shares during the thirty (30) trading days immediately

conversion, the Conversion Amount shall first be applied to reduce the accrued
interest due on the Loan as of the Conversion Date, and any remaining portion of

If Monsanto elects to receive Conversion Shares (including any Default
Conversion Shares pursuant to Section 5.03 hereof) in lieu of repayment, the
Company shall deliver to Monsanto, simultaneously with the delivery of the
Conversion Shares, an opinion from counsel to the Company in a form reasonably
satisfactory to Monsanto relating to the issuance of the Conversion Shares.

                    ------------------                                     
Default, Monsanto may, at its election, without notice of its election and

and payable, to the extent and only to the extent of the Repayment Portion of
Cumulative Free Cash Flow that has not been paid to Monsanto, without
presentment, protest or further notice of any kind, all of which are hereby
expressly waived by the Company.

     Section 5.03.  Additional Remedy.  Upon the occurrence and during the
                    -----------------                                     
continuation of an Event of Default, in addition to the other remedies set forth
in this Agreement, Monsanto may demand that the Company convert all or any
portion of the principal and accrued interest under the Loan into shares of
common stock of the Company at the average of the closing market prices for such
shares during the thirty (30) trading days immediately preceding the Default
Conversion Date (hereafter defined) for such Loan; provided, however, that in no
event shall Monsanto elect to convert principal and accrued interest into more
than eight million (8,000,000) shares of common stock of the Company (as such
number is adjusted for stock dividends, stock splits and similar events
affecting holders of the Company's common stock). In order to exercise its
conversion rights, at any time after the occurrence and during the continuation
of an Event of Default, Monsanto may send a written notice (the "Default
Conversion Notice") to the Company that Monsanto intends to exercise such
conversion rights.  The Default Conversion Notice shall specify (i) the amount
of the principal and accrued interest that Monsanto intends to convert (the
"Default

                                      -28-
<PAGE>
 
Conversion Amount") and (ii) the date as of which such conversion shall take
place (the "Default Conversion Date"), which date shall not be later than ten
(10) days after the date of the Default Conversion Notice. If Monsanto properly
notifies the Company as provided in the preceding sentences, then within five
(5) business days after the Default Conversion Date, the Company shall issue to
Monsanto a number of shares (the "Default Conversion Shares") of common stock of
the Company (rounded to the next lowest full share) equal to the Default
Conversion Amount divided by the average of the closing market prices for such
shares during the thirty (30) trading days immediately preceding the Default
Conversion Date. Any portion of the Default Conversion Amount not so converted
(i.e., because such amount would require conversion into a fractional share)
shall be paid to Monsanto in cash. Upon any such conversion, the Default
Conversion Amount (including any portion thereof paid to Monsanto in cash) shall
first be applied to reduce the accrued interest due on the Loan as of the
Default Conversion Date, and any remaining portion of the Default Conversion
Amount shall be applied to reduce the principal due on such Loan.

     Section 5.04.  Company's Obligations.  The Company recognizes that, if
                    ---------------------                                  
the Company fails to perform, observe or discharge any of its obligations under
this Agreement or the other collateral agreements hereto, a remedy at law may
not provide adequate relief to Monsanto; therefore, the Company agrees that
Monsanto shall be entitled to seek temporary and permanent injunctive relief in
any such case without the necessity of proving actual damages. All of Monsanto's
rights and remedies granted under this Agreement and the collateral agreements
hereto are cumulative and nonexclusive. The Company shall pay upon demand all
costs and expenses, including, without limitation, reasonable attorneys' fees
and expenses, incurred by Monsanto in enforcing this Agreement. All such sums
not paid on demand shall be treated as outstanding principal under the Note.

time held and other indebtedness at any time owing by Monsanto to or for the
credit or the account of the Company or any of the Subsidiaries against any and
all of the obligations of the Company now or hereafter existing under this

Portion of the Cumulative Free Cash Flow that has not been paid to Monsanto,
irrespective of whether or not Monsanto shall have made any demand under this
Agreement or the Note and although such obligations may be unmatured. The rights
of Monsanto under this Section 6.01 are in addition to other rights and remedies
(including, without limitation, other rights of setoff) which Monsanto may have.

Indebtedness, or securities, notes or other evidences of indebtedness issued in
exchange for such Senior Indebtedness; provided, however, that in no event shall
the obligations of the Company under the Company Credit Facility Agreement
constitute Senior Indebtedness under this Agreement.  No payment on account of
principal or interest on the Subordinated Indebtedness shall be made if, at the
time of such payment or immediately after giving the effect thereto, (i) there
shall exist a default in any payment with respect to any Senior Indebtedness or
(ii) there shall have occurred an event of default (other than a default in the
payment of amounts due thereon) with respect to any Senior Indebtedness, as
defined in the instrument under which the same is outstanding, permitting the
holders thereof to accelerate the maturity thereof, and such event of default
shall not have been cured or waived or shall not have ceased to exist.
Notwithstanding the foregoing or any other provision of this Section 7.01,
nothing in this Section 7.01 shall restrict or otherwise limit Monsanto's or
Company's rights under Sections 1.02, 1.06 and 5.03 hereof.

          (b)  In the event of any distribution, dividend, or application,
partial or complete, voluntary or involuntary, by operation or law or otherwise,
of all or any part of the assets of the Company or of the proceeds thereof to
the creditors of the Company or upon any indebtedness of the Company, occurring
by reason of the liquidation, dissolution, or other winding up of the Company,
or by reason of any execution sale, or bankruptcy, receivership, reorganization,
arrangement, insolvency, liquidation or foreclosure proceeding of or for the
Company or involving its property, no dividend, distribution or application
shall be made, and Monsanto shall not be entitled to receive or retain any
dividend, distribution, or application on or in respect of principal of or
interest on Subordinated Indebtedness, unless and until all principal of and any
interest on Senior Indebtedness then outstanding shall have been paid and
satisfied in full, and in any such event any dividend, distribution or
application otherwise payable in respect of Subordinated Indebtedness shall be
paid and applied on Senior Indebtedness until such Senior Indebtedness has been
fully paid and satisfied.

          (c)  The holders of Senior Indebtedness need not at any time give
Monsanto notice of any kind of the creation or existence of any Senior
Indebtedness, nor of the amount or terms thereof, all such notice being hereby
expressly waived.  Also, the holders of Senior Indebtedness may at any time,
from time to time, without the consent of or notice to Monsanto, without
incurring responsibility to Monsanto, and without impairing or releasing the
obligation of Monsanto under this Agreement (i) renew, refund or extend the
maturity of any Senior Indebtedness, or any part thereof, or otherwise revise,
amend or alter the terms and conditions thereof, (ii) sell, exchange, release or
otherwise deal with any property by whomsoever at any time pledged, mortgaged or
otherwise hypothecated or subjected to a lien to secure any Senior Indebtedness,
and (iii) exercise or refrain from exercising any rights against the Company and
others, including Monsanto.

          (d)  Monsanto shall not sell, assign or otherwise transfer any
Subordinated Indebtedness, or any part thereof, except (i) upon the agreement of
the transferee or assignee to abide by and be bound by the terms hereof and (ii)
when Monsanto may assign its rights under the Stockholders Agreement dated of
even date herewith between Company and Monsanto.

          (e)  Monsanto shall cause all Subordinated Indebtedness to be at all
times evidenced by the Note of the Company and shall cause such Note to bear
thereon a legend substantially as follows:

          "The indebtedness evidenced by this Note is subordinate to any and all
          indebtedness, obligations and liabilities of the maker hereof to the
          holders of Senior Indebtedness in the manner and to the extent set
          forth in the Credit Facility Agreement (as defined below) to which
          reference is hereby made for a more full statement thereof."

                                      -32-

          (f)  If, notwithstanding the provisions of this Agreement, Monsanto
shall receive any payment of principal or interest on Subordinated Indebtedness
which the Company is not entitled to make pursuant to the terms hereof, whether
or not Monsanto has knowledge that the Company is not entitled to make such
payment, Monsanto shall promptly account for such payment and upon the demand of
the holders of Senior Indebtedness pay over such payment to such holders for
application to the Senior Indebtedness owing to such holders.  No payment or any
distribution received by the holders of the Senior Indebtedness in respect of
Subordinated Indebtedness pursuant to any of the terms hereof shall entitle
Monsanto to any right, whether by virtue of subrogation or otherwise, in and to
any Senior Indebtedness unless and until all Senior Indebtedness has been fully
paid and satisfied and any commitment of the holders of Senior Indebtedness to
extend Senior Indebtedness to the Company has terminated.

necessary, in connection with their obligations under this AGREEMENT, for NEWCO

     4.2  CONFIDENTIALITY AND LIMITED USE:
          --------------------------------

     (a) With respect to all Confidential Information, both NEWCO and MONSANTO
and AFFILIATES of either party agree as follows, it being understood that
"recipient" indicates the party

                                       2
<PAGE>
 
receiving the confidential, proprietary information from the other "disclosing"
party.  Confidential Information disclosed to the recipient shall remain the
property of the disclosing party and shall be maintained in confidence by the

compliance with law or regulations; provided that the disclosing party provides
the other party with notice and takes reasonable measures to obtain confidential
treatment thereof; (ii) in confidence to attorneys, accountants, banks and
financial sources and their advisors; or (iii) in confidence, in connection with

          -----------                                                          
not apply to any of the Confidential Information which

          (a)  is publicly available by publication or other documented means or
later becomes likewise publicly available through no act or fault of recipient;
or

          (b)  is already known to recipient before receipt from the disclosing
party, as demonstrated by recipient's written records; or

          (c)  is made known to recipient by a third party who did not obtain it
directly or indirectly from the disclosing party and who does not obligate
recipient to hold it in confidence.

Specific information should not be deemed to be within any of these exclusions
merely because it is embraced by more general information falling within these
exclusions.

     4.4  DISCLOSURES TO PERSONNEL:  Recipient agrees to advise those of its
          -------------------------

of these

                                       3

confidentiality and limited use obligations and agrees, prior to any disclosure
of Confidential Information to such individuals or entities, to make them bound
by obligations of confidentiality and limited use of the same stringency as
those contained in this AGREEMENT.

     4.5  RETURN OF CONFIDENTIAL INFORMATION:  Upon termination of this
          -----------------------------------                          
AGREEMENT, originals and copies of Confidential Information in written or other
tangible form will be returned to the disclosing party by recipient or destroyed
by recipient.  One copy of each document may be retained in the custody of the
recipient's legal counsel solely to provide a record of what disclosures were
made.

     4.6  CONFIDENTIAL STATUS OF AGREEMENT:   The terms of this AGREEMENT shall
          ---------------------------------                                    
be deemed to be Confidential Information and shall be dealt with according to
the confidentiality requirements of this Article 4.  Both parties agree,
furthermore, that neither party will make public disclosures concerning other
specific terms of this AGREEMENT without obtaining the prior written consent of
the other party, which consent shall not be unreasonably withheld.

conveyances and grants in accordance with the articles hereof.  MONSANTO further

would be infringed by the use or sale of LICENSED PRODUCTS other than LICENSED
PATENT RIGHTS.  It is expressly understood, however, that in making the
conveyances and grants under this Agreement with the exception of the foregoing
provisions of this paragraph, MONSANTO MAKES NO REPRESENTATION, EXTENDS NO
WARRANTIES, EITHER EXPRESS OR IMPLIED, AND ASSUMES NO RESPONSIBILITIES
WHATSOEVER WITH RESPECT TO:

          a)   THE SCOPE OR VALIDITY OF ANY PATENT WHICH MAY FALL WITHIN
LICENSED PATENT RIGHTS; OR

          b)   ANY USE OF LICENSED PRODUCT BEING FREE FROM INFRINGEMENT OF

<PAGE>
 
     6.2  This Agreement may be terminated by NEWCO by giving MONSANTO thirty
(30) days prior written notice of its intention to terminate.

     6.3  Except as provided in paragraph 6.2 , neither NEWCO nor MONSANTO may
terminate this Agreement unless the other party is in breach of this Agreement
and does not remedy such breach within thirty (30) days written notice of such
breach.

                         ARTICLE 7  PATENT LITIGATION

     7.1  MONSANTO shall have power to institute and prosecute at its own
discretion and expense suits for infringement of the LICENSED PATENT RIGHTS.
All expenses in such suits will be borne entirely by MONSANTO, and MONSANTO
shall retain all judgements or awards arising from these suits.

     7.2  If MONSANTO shall fail to commence suit on an infringement hereunder
within one (1) year after receipt of NEWCO's written request to do so, or at any
time MONSANTO so notifies NEWCO, NEWCO shall have the right to bring and
prosecute any such suits at its cost and expense through attorneys of its
selection, in its own name, and all sums received or recovered by NEWCO in or by
reason of such suits shall be retained by NEWCO; provided, however, NEWCO shall
have no such right during the time MONSANTO is prosecuting any infringement suit
in such country. In any such suit MONSANTO agrees to be joined as a party, if
necessary.  Any costs to MONSANTO because of such suit brought by NEWCO, other
than any attorney fee paid by MONSANTO for its own representation, shall be
reimbursed by NEWCO.

                   ARTICLE 8  PATENT FILINGS AND PROSECUTION

maintaining any patent application relating to LICENSED PATENT RIGHTS, including
any foreign counterpart.

undertaken in the prosecution of all patents and applications.  In the event
that MONSANTO decides to discontinue prosecution or maintenance of any patent or
patent application within LICENSED PATENT RIGHTS, it will notify NEWCO so that
NEWCO can assume the responsibility for prosecution or maintenance of such
patent or patent application at NEWCO's own costs.

party, as demonstrated by recipient's written records; or

          (c)  is made known to recipient by a third party who did not obtain it
directly or indirectly from the disclosing party and who does not obligate
recipient to hold it in confidence.

Specific information should not be deemed to be within any of these exclusions
merely because it is embraced by more general information falling within these
exclusions.

     4.4  DISCLOSURES TO PERSONNEL:  Recipient agrees to advise those of its

be deemed to be Confidential Information and shall be dealt with according to
the confidentiality requirements of this Article 4.  Both parties agree,
furthermore, that neither party will make public disclosures concerning other
specific terms of this AGREEMENT without obtaining the prior written consent of
the other party, which consent shall not be unreasonably withheld.

the other party with notice and takes reasonable measures to obtain confidential
treatment thereof; (ii) in confidence to attorneys, accountants, banks and

later becomes likewise publicly available through no act or fault of recipient;
or

          (b)  is already known to recipient before receipt from the disclosing
party, as demonstrated by recipient's written records; or

          (c)  is made known to recipient by a third party who did not obtain it
directly or indirectly from the disclosing party and who does not obligate
recipient to hold it in confidence.

Specific information should not be deemed to be within any of these exclusions
merely because it is embraced by more general information falling within these
exclusions.

     5.4  DISCLOSURES TO PERSONNEL:  Recipient agrees to advise those of its
          -------------------------

tangible form will be returned to the disclosing party by recipient or destroyed

          ---------------------------------                                   
be deemed to be Confidential Information and shall be dealt with according to
the confidentiality requirements of this Article 5.  Both parties agree,
furthermore, that neither party will make public disclosures concerning other
specific terms of this AGREEMENT without obtaining the prior written consent of
the other party, which consent shall not be unreasonably withheld.

scope as the license conveyed under this AGREEMENT and having terms which are
more favorable as to earned royalty than the terms granted to NEWCO hereunder,
then MONSANTO shall advise NEWCO as to such more favorable earned royalty terms.
NEWCO shall, at its election, be entitled upon notice to MONSANTO to have this
AGREEMENT amended to substitute such earned royalty terms for the earned royalty
terms of this AGREEMENT as of the date upon which such license containing the

any respect, such invalidity, illegality or unenforceability shall not affect
any other provisions hereof, but this AGREEMENT shall be construed as

grants to NEWCO and AFFILIATES of NEWCO under the LICENSED PATENT RIGHTS and
FATTY ACID METABOLISM KNOW-HOW and during the TERM OF THIS AGREEMENT a non-
exclusive, royalty-bearing, world-wide sublicense to make and use LICENSED
PRODUCTS and the right to sell or sublicense others to sell NEWCO OILSEED CROP
PLANTS.

     3.2 In consideration for the license and rights granted herein, NEWCO shall
pay MONSANTO a license maintenance fee of ****** beginning on the first
anniversary of the EFFECTIVE DATE OF THIS AGREEMENT and continuing annually on
each anniversary. This license maintenance fee shall be credited against any
royalties due under section below.

     3.3  In further consideration for the license and rights granted herein,
NEWCO shall pay MONSANTO an earned royalty of ***** of NET VALUE ADDED.

                     ARTICLE 4  REPORTS, BOOKS AND RECORDS

     4.1  Within thirty (30) days of the end of the calendar annual period
during which this Agreement shall be executed and delivered and within thirty
(30) days after the end of each following annual period, NEWCO shall make a
written report to MONSANTO setting forth the total sales, the NET VALUE ADDED
and the number of LICENSE PRODUCTS sold by NEWCO and any AFFILIATES of NEWCO.
If there are no sales, a statement to that effect shall be made by NEWCO to
MONSANTO.  At the time each report is made, NEWCO shall pay to MONSANTO the
royalties shown by such report to be payable hereunder.

     4.2  NEWCO shall keep Books and Records in such reasonable detail as will
permit the reports provided for in paragraph 4.1 hereof to be made and the
royalties payable by NEWCO hereunder to be determined.  NEWCO further agrees to
permit such Books and Records to be inspected and audited from time to time (but

necessary to verify the reports provided for in paragraph 4.1; provided,
however, that such auditor shall

is granted hereunder shall be in issue, which judgment or decree shall become
not further reviewable through the exhaustion of all permissible applications
for rehearing or review by a superior tribunal or through the expiration of the
time permitted for such application, (such a judgment or decree being
hereinafter referred to as an "Irrevocable Judgment"), the construction placed
on any such claim by such Irrevocable Judgment shall thereafter be followed not
only as to such claim, but also as to all claims to which such construction
applies, with respect to acts occurring thereafter and if an Irrevocable
Judgment shall hold any claim invalid, NEWCO shall be relieved thereafter from
including in its reports hereunder that portion of the royalties due under
Article 3 payable only because of such claim or any broader claim to which such
Irrevocable Judgment shall be applicable, and from the performance of any other
acts required by this Agreement only because of any such claims.

party, as demonstrated by recipient's written records; or

          (c)  is made known to recipient by a third party who did not obtain it
directly or indirectly from the disclosing party and who does not obligate
recipient to hold it in confidence.

Specific information should not be deemed to be within any of these exclusions
merely because it is embraced by more general information falling within these
exclusions.

     6.4  DISCLOSURES TO PERSONNEL:  Recipient agrees to advise those of its

Article 6.  Both parties agree, furthermore, that neither party will make public

the prior written consent of the other party, which consent shall not be

compliance with law or regulations; provided that the disclosing party provides
the other party with notice and takes reasonable measures to obtain confidential
treatment thereof; (ii) in confidence to attorneys, accountants, banks and
financial sources and their advisors; or (iii) in confidence, in connection with
a license, sublicense, or acquisition so long as, in each case, the entity to
which disclosure is made is bound to confidentiality on terms consistent with
those set forth herein.

     4.3  EXCEPTIONS:  The obligations of confidentiality and limited use shall
          -----------                                                          
not apply to any of the Confidential Information which

          (a)  is publicly available by publication or other documented means or
later becomes likewise publicly available through no act or fault of recipient;
or

          (b)  is already known to recipient before receipt from the disclosing
party, as demonstrated by recipient's written records; or

          (c)  is made known to recipient by a third party who did not obtain it
directly or indirectly from the disclosing party and who does not obligate
recipient to hold it in confidence.

Specific information should not be deemed to be within any of these exclusions
merely because it is embraced by more general information falling within these
exclusions.

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

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

     1.1  MONSANTO has developed and has a present intention to continue to
develop technology which is useful in the production of genetically modified
cotton plants exhibiting resistance to Lepidopteran insects. Such MONSANTO
TECHNOLOGY is the subject of certain patents and patent applications.  MONSANTO
also possesses certain know-how and germplasm relating to such cotton plants.

     1.2  MONSANTO and CALGENE entered into commercial License Agreements each
dated April 22, 1993 relating to technology useful in production of genetically-
modified cotton plants exhibiting resistance to Lepidopteran insects.

     1.3  MONSANTO and CALGENE now desire to revise the manner in which the
above-described MONSANTO technology is to be commercialized and hereby amend the
RELATED AGREEMENTS as set forth below.

     1.4  MONSANTO and CALGENE are each interested in entering into a
contractual arrangement under which MONSANTO would license cotton farmers the
right to use LICENSED COMMERCIAL SEED exhibiting such resistance to Lepidopteran
insects to produce a single cotton crop in THE TERRITORY and CALGENE would
produce and sell LICENSED COMMERCIAL SEED to cotton farmers licensed by MONSANTO
to use such LICENSED COMMERCIAL SEED.

introduce an ALTERNATE GENE into cotton which has the effect of eliminating or
reducing the royalty due to a third party by MONSANTO under a License Agreement
and CALGENE makes such introduction at no cost to MONSANTO, the net savings,
after offsetting any royalty payable to any third party by MONSANTO for use of
such ALTERNATE GENE, shall be shared on a 50:50 basis by reducing the applicable
MONSANTO ROYALTY PERCENTAGE. For example, if a third party royalty of eight and
one-half percent (8.5%) of MONSANTO'S seventy-one percent (71%) ROYALTY is
eliminated by CALGENE'S commercializing an ALTERNATE GENE as requested by
MONSANTO, and no other royalty is owed to a third party for such ALTERNATE GENE,
then the MONSANTO ROYALTY PERCENTAGE shall be reduced to sixty-eight percent
[.71 - (.71 x .085)/2 = .68]; or

          (b)    the equivalent percentage as would have been due under the
terms of the RELATED AGREEMENTS prior to amendment herein for LICENSED
COMMERCIAL SEED the production, use or sale of which would, without a license,
infringe a claim of the LICENSED

cotton farmers licensed by MONSANTO for use in THE TERRITORY; provided however
that, CALGENE shall not be permitted to commercialize such LICENSED COMMERCIAL
SEED in the area East of Oklahoma and Texas prior to January 1, 1997..

     3.2  TRANSITION TO LEPIDOPTERAN-ACTIVE MONSANTO GENE:
          ------------------------------------------------

          (a)  MONSANTO shall promptly initiate an aggressive breeding program
to introduce LEPIDOPTERAN-ACTIVE MONSANTO GENE(S) into a mutually agreed upon
number of CALGENE CULTIVARS. MONSANTO shall provide CALGENE with BC\\3\\F\\3\\
seed of such CALGENE B.T. CULTIVARS to facilitate aggressive development of
LEPIDOPTERAN-ACTIVE MONSANTO GENE containing LICENSED COMMERCIAL SEED by
CALGENE.
          (b) CALGENE shall be obligated to replace all LICENSED COMMERCIAL SEED
containing LICENSED CALGENE GENE with LICENSED COMMERCIAL SEED containing
LEPIDOPTERAN ACTIVE MONSANTO GENE(S) beginning in planting year 1999; provided
that, one or more CALGENE CULTIVARS containing a LEPIDOPTERAN-ACTIVE MONSANTO
GENE have demonstrated yield equivalency in at least two years of multi-located
replicated yield trial conducted jointly by CALGENE and MONSANTO using a
protocol approved by MONSANTO.

          (c)  CALGENE'S license to make, use, an sell LICENSED COMMERCIAL SEED
containing the LICENSED CALGENE GENE shall be limited, and the amount of such
LICENSED COMMERCIAL SEED sold: (i) for planting year 2000 shall not exceed
eighty percent (80%) of CALGENE'S total seed sales of CALGENE B.T. CULTIVARS for
planting year 1999, (ii) for planting year 2001 shall not exceed fifty percent
(50%) of CALGENE'S total seed sales of CALGENE B.T. CULTIVARS for planting year
1999, and (iii) for planting year 2002 shall not exceed twenty percent (20%) of
CALGENE'S total seed sales of CALGENE B.T. CULTIVARS for planting year 1999;
provided however that, CALGENE and MONSANTO may meet and discuss the potential
for delaying the phase-out of LICENSED COMMERCIAL SEED containing the LICENSED
CALGENE GENE.

          (d)  MONSANTO shall reimburse the reasonable incremental development
costs incurred by CALGENE in years 1997 through 2000 which are directly and
solely related to the introduction of LEPIDOPTERAN-ACTIVE MONSANTO GENE(S) into
the Calgene germplasm, not to exceed Five Hundred Thousand Dollars ($500,000)
per year; provided, that such costs are clearly attributable solely to the
introduction of the LEPIDOPTERAN-ACTIVE MONSANTO GENE(S)  and are
<PAGE>
 
not incurred as a result of normal and customary development of new CALGENE
CULTIVARS.  At the beginning of each subject year, CALGENE shall submit to
MONSANTO a written development plan outlining such incremental development costs
which CALGENE believes are subject to re-imbursement pursuant to this Subsection
3.2(d).  CALGENE are MONSANTO shall mutually agree upon the elements of the
development plan that are subject to such reimbursement.  At the end of each
subject year, CALGENE shall submit to MONSANTO a written report outlining the
incremental development costs actually incurred by CALGENE for the subject year.
Payment shall be due by MONSANTO within thirty (30) days of the receipt of such
report by MONSANTO.

          (e)  In the event that the yield trials conducted pursuant to
Subsection 3.2(b) do not indicate yield equivalency, initiation of transition to
a LEPIDOPTERAN-ACTIVE MONSANTO GENE containing LICENSED COMMERCIAL SEED shall be
delayed for the period of time until such yield equivalency is reasonably
demonstrated.

          (f)  In the event that CALGENE is selling seed of a CALGENE CULTIVAR
expressing a B.T. TOXIN by December 31, 1998, but is not selling  LICENSED
COMMERCIAL SEED containing a LICENSED CALGENE GENE by such date, initiation of
transition to a LEPIDOPTERAN-ACTIVE MONSANTO GENE containing LICENSED COMMERCIAL
SEED shall be delayed until the planting year following the first planting year
in which CALGENE first sells LICENSED CALGENE GENE containing LICENSED
COMMERCIAL SEED.

          (g)  CALGENE shall not be licensed under LICENSED PATENT RIGHTS to
develop, produce, have produced or sell LICENSED COMMERCIAL SEED containing the

     3.3  LICENSE TO MULTIPLY LICENSED COMMERCIAL SEED:  The rights granted to
          --------------------------------------------                        
CALGENE include the right to multiply such LICENSED COMMERCIAL SEED (for
subsequent sale to licensed cotton farmers) directly or through third party
contract growers selected by CALGENE in THE TERRITORY and licensed by MONSANTO
or, after notice to and approval by MONSANTO (which approval will not be
unreasonably delayed or denied), outside THE TERRITORY where CALGENE has
obtained all necessary governmental approvals, and to carry out all other
activities reasonably necessary for the production, and for the sale in THE
TERRITORY, of LICENSED COMMERCIAL SEED.

     3.4  OPTIONS FOR LICENSES TO SUBSEQUENT GENE(S):
          -------------------------------------------
<PAGE>
 
          (a)  MONSANTO grants to CALGENE an option to a license in the
TERRITORY as described in Subsections 3.1, 3.2 and 3.3, to SUBSEQUENT GENE(S)
for which MONSANTO obtains GOVERNMENT APPROVAL, and MONSANTO TECHNOLOGY related
thereto for use in cotton in THE TERRITORY for so long as CALGENE is not
developing a cotton seed containing a THIRD-PARTY LEPIDOPTERAN-ACTIVE GENE and
until October 11, 2008.

          (b)  CALGENE shall provide prompt written notice to MONSANTO should
CALGENE initiate development of cotton seed containing a THIRD-PARTY
LEPIDOPTERAN-ACTIVE GENE.

          (c)  For so long as the option to such licenses pursuant to Subsection
3.4(a) is effective, MONSANTO shall notify CALGENE in writing whenever MONSANTO
decides to authorize a SUBSEQUENT GENE for COMMERCIAL DEVELOPMENT in THE
TERRITORY.  Such notification shall be given to CALGENE with respect to each
LEPIDOPTERAN-ACTIVE MONSANTO GENE not later than thirty (30) days after its DATE
OF APPROVAL FOR COMMERCIAL DEVELOPMENT.  CALGENE may exercise the option to
obtain a license for such LEPIDOPTERAN-ACTIVE MONSANTO GENE by notifying
MONSANTO in writing within sixty (60) days after the date on which MONSANTO
gives CALGENE such notice of the DATE OF APPROVAL FOR COMMERCIAL DEVELOPMENT.
With respect to a LEPIDOPTERAN-ACTIVE MONSANTO GENE, the license under the terms
of this Agreement shall become effective upon receipt by MONSANTO of CALGENE'S
notice of exercise of its option.

     3.5  PROHIBITION AGAINST MODIFICATION OF GENETIC MATERIALS:      
          -----------------------------------------------------          

          (a)  CALGENE shall not modify any LEPIDOPTERAN-ACTIVE MONSANTO GENE
nor modify or use any isolated regulatory control sequences contained in a
LEPIDOPTERAN-ACTIVE MONSANTO GENE, for any purpose without the prior written
consent of MONSANTO. 

          (b)  CALGENE shall not be permitted to produce, have produced and/or
commercialize new cotton transformants containing any LEPIDOPTERAN-ACTIVE
MONSANTO GENE without the prior written approval of MONSANTO.

     3.6  CONDITIONS ON LICENSE:  In partial consideration for the above
          ---------------------                                         
LICENSES:
          (a) CALGENE shall not insert into a line of LICENSED COMMERCIAL SEED
containing a LEPIDOPTERAN-ACTIVE MONSANTO GENE, any other non-naturally
occurring gene or genes which result in INSECT RESISTANCE without the prior
written consent of MONSANTO.
<PAGE>
 
MONSANTO shall provide such consent if MONSANTO has permitted the same or
similar insertions by any other licensee of the subject LEPIDOPTERAN-ACTIVE
MONSANTO GENE(S) for use in cotton.  Provided, however, that CALGENE'S
modification of such lines of LICENSED COMMERCIAL SEED and MONSANTO'S obligation
with respect to such lines shall be subject to equivalent terms and conditions
as may be applicable to such third party licensee.  A gene shall be considered
naturally-occurring if it exists in a cotton cultivar and has not been produced
as a result of tissue culture selection, genetic engineering using recombinant
DNA techniques, or any other in vitro modification to the cotton plant or plants
from which was isolated.

          (b)  CALGENE shall choose VARIETAL NAMES, VARIETAL NUMBERS, or
DISTINCTIVE NOMENCLATURE to designate cotton seed of CALGENE'S varieties which
contains LEPIDOPTERAN-ACTIVE MONSANTO GENE(S).  If the VARIETAL NUMBER used as
part of the name of a variety of LICENSED COMMERCIAL SEED has not been used by
CALGENE in connection with the sale of NON-B.T. COTTON SEED prior to the DATE OF
FIRST COMMERCIAL SALE, CALGENE shall not use such VARIETAL NUMBER to identify
cotton seed which contains a recombinant gene for INSECT RESISTANCE other than a
LEPIDOPTERAN-ACTIVE MONSANTO GENE.  If the VARIETAL NUMBER used as part of the
name of a variety of LICENSED COMMERCIAL SEED has been used by CALGENE in
connection with the sale of NON-B.T. COTTON SEED prior to the DATE OF FIRST
COMMERCIAL SALE, CALGENE may use such VARIETAL NUMBER to identify cotton seed
which does not contain LEPIDOPTERAN-ACTIVE MONSANTO GENE(S), but if such
VARIETAL NUMBER is used to identify cotton seed which does not contain a
LEPIDOPTERAN-ACTIVE MONSANTO GENE, CALGENE shall not use such VARIETAL NUMBER in
connection with DISTINCTIVE NOMENCLATURE, used to identify LICENSED COMMERCIAL
SEED, to identify cotton seed which does not contain a LEPIDOPTERAN-ACTIVE
MONSANTO GENE.  For examples, (1) if, prior to the DATE OF FIRST COMMERCIAL
SALE, CALGENE has not sold cotton seed using the VARIETAL NUMBER "235," and
after the DATE OF FIRST COMMERCIAL SALE sells LICENSED COMMERCIAL SEED with a
VARIETAL NAME such as "ST 235 Lep-Con", CALGENE may thereafter identify NON-B.T.
COTTON SEED by a VARIETAL NAME such as "ST 235", but cannot identify cotton seed
which contains a recombinant gene for INSECT RESISTANCE other than a
LEPIDOPTERAN-ACTIVE MONSANTO GENE using the VARIETAL NUMBER "235".  Thus, such
seed could not be identified as "ST 235 I.R." but could be identified as "ST 335
I.R." (2) If, prior to the DATE OF FIRST COMMERCIAL SALE, CALGENE has sold
cotton seed using the VARIETAL NUMBER "275" and thereafter sells seed containing
a LEPIDOPTERAN-ACTIVE
<PAGE>
 
MONSANTO GENE using such VARIETAL NUMBER with a DISTINCTIVE NOMENCLATURE, such
as in the VARIETAL NAME "ST 275 Lep-Con," CALGENE may thereafter (a) identify
NON-B.T. COTTON SEED by a VARIETAL NAME such as "ST 275", and (b) may also
identify cotton seed which contains a recombinant gene for INSECT RESISTANCE
other than a LEPIDOPTERAN-ACTIVE MONSANTO GENE(S) using the VARIETAL NUMBER
"275" but must use some DISTINCTIVE NOMENCLATURE other than "Lep-Con" in
connection with such seed, so that the VARIETAL NAME "ST 275 I.R." could be used
to identify such seed but VARIETAL NAMES such as "ST 275 Lep-Con", "ST 275 Lep-
Con Plus", or "CALGENE 275 Lep-Con" could not be used.

          (c)  CALGENE shall conspicuously display on all packages containing
LICENSED COMMERCIAL SEED, covered by MONSANTO PATENT RIGHTS, and in all invoices
relating to such LICENSED COMMERCIAL SEED to be sold or transferred to third
parties, the following notice, or a notice having the same meaning and effect,
with the blanks appropriately filled in:

               THESE SEEDS ARE COVERED UNDER U. S. PATENT(S) ______________. NO
               SUBLICENSE IS CONVEYED UNDER SAID PATENTS TO USE THESE SEEDS
               SOLELY BY THE PURCHASE OF SUCH SEEDS.  A SUBLICENSE UNDER SAID
               PATENTS TO USE THESE SEEDS TO PRODUCE A SINGLE COTTON CROP MUST
                                                                          ----

         (a)  CALGENE shall conspicuously display the BOLLGARD" GENE TRADEMARK
and accompanying logo on all packages of LICENSED COMMERCIAL SEED containing a
LEPIDOPTERAN-ACTIVE MONSANTO GENE. After initial use of the BOLLGARD" GENE TRADE
MARK and accompanying logo, any alteration of the size and location of such
TRADEMARK and accompanying logo shall require the written approval of MONSANTO.

          (b)  It is agreed that the BOLLGARD" GENE TRADEMARK shall be licensed
to CALGENE on a non-exclusive royalty-free basis pursuant to the BOLLGARD" GENE
TRADEMARK LICENSE AGREEMENT.  The parties shall execute said BOLLGARD" GENE
TRADEMARK LICENSE AGREEMENT following identification of the final graphic form
of the BOLLGARD" GENE TRADEMARK and accompanying logo by MONSANTO.

          (c)  The BOLLGARD" GENE TRADEMARK shall be utilized in the manner
specified in the BOLLGARD" GENE TRADEMARK LICENSE AGREEMENT.  Provided, however,
that
<PAGE>
 
the size of the BOLLGARD" GENE TRADEMARK shall be reasonable in relation to the
overall size of the package and shall be smaller than the largest representation
of the CALGENE trademark appearing on the package.  Provided, further, that the
BOLLGARD" GENE TRADEMARK shall not unreasonably detract from the appearance of
such CALGENE package nor be so similar to any existing CALGENE trademark as to
create confusion.  MONSANTO shall inform CALGENE of the final graphic form of
the BOLLGARD" GENE TRADEMARK and accompanying logo to be used on such LICENSED
COMMERCIAL SEED as soon as practicable, and in no event later than June 15 prior
to the marketing year in which the BOLLGARD" GENE TRADEMARK is to be used, and
shall reimburse CALGENE for any increase in the cost of the package necessitated
directly and solely by the application of the BOLLGARD" GENE TRADEMARK and for
the cost of any unused packaging or other materials which cannot be used because
of any subsequent change requested by MONSANTO in the BOLLGARD" GENE TRADEMARK.

     3.8  LIMITATIONS ON LICENSE:  This Agreement is not to be construed as
          ----------------------                                           
including a grant from MONSANTO to CALGENE of any license, sublicense or other
right: (a) to make or sell the LICENSED CALGENE GENE, LEPIDOPTERAN-ACTIVE
MONSANTO GENE(S) or MONSANTO TECHNOLOGY, (b) to use LICENSED CALGENE
GENE,LEPIDOPTERAN-ACTIVE MONSANTO GENE(S) or MONSANTO TECHNOLOGY for any purpose
other than those expressly set forth herein.

     3.9  EDUCATIONAL PROGRAM TO DISCOURAGE FARMER-SAVED SEED:     CALGENE shall
          ---------------------------------------------------                   
employ reasonable efforts on a continuing basis to proactively educate the
purchasers of LICENSED COMMERCIAL SEED with the nature of the limited-use
license granted to such cotton farmers by MONSANTO, the benefits of purchasing
LICENSED COMMERCIAL SEED annually and the disadvantages of using farmer-saved
seed and applicable legal restrictions.

     3.10 THIRD PARTY VIOLATIONS OR INVALIDITY OF RESTRICTIONS ON LICENSE:  The
          ---------------------------------------------------------------      
use of LICENSED COMMERCIAL SEED by purchasers for purposes other than, or in
addition to, production of a single commercial commodity crop unless expressly
authorized by CALGENE shall not be considered a breach of this Agreement.  The
LICENSE granted to CALGENE shall not be revoked, diminished, or otherwise
affected in the event that the limitations and restrictions of such
<PAGE>
 
license to purchasers are found to be unenforceable, in whole or in part, by a
court of competent jurisdiction.

     3.11 IDENTIFICATION OF FIELDS PLANTED WITH FARMER-SAVED SEED:    CALGENE
          -------------------------------------------------------            
and MONSANTO shall cooperate in a reasonable effort to develop and employ
methods or techniques, which can be employed in a commercially efficient manner,
to identify fields of cotton that are planted with seed saved from a crop
produced from LICENSED COMMERCIAL SEED.  All costs associated with the
cooperative efforts to develop and employ such methods and techniques shall be
borne by MONSANTO.

          MONSANTO has not:

               (1)  authorized for COMMERCIAL DEVELOPMENT (and delivered to
               CALGENE seed containing) a LEPIDOPTERAN-ACTIVE MONSANTO GENE that

          MONSANTO has not:

               (1)  authorized for COMMERCIAL DEVELOPMENT (and delivered to
               CALGENE seed containing) at least one (1) or more other
               LEPIDOPTERAN-ACTIVE MONSANTO GENE(S) that result in plants of at

     6.2  COMPENSATION PERIOD:
          ------------------- 

          (a)  With respect to each LEPIDOPTERAN-ACTIVE MONSANTO GENE or
LICENSED CALGENE GENE, MONSANTO'S obligation to pay CALGENE the SEED SERVICES
FEE described in Subsection 6.1(a) shall begin on the DATE OF FIRST COMMERCIAL
LICENSING of LICENSED COMMERCIAL SEED and shall end upon the expiration of the
last-to-expire patent of LICENSED PATENT RIGHTS with one (1) or more enforceable

in THE TERRITORY.

          (b)  CALGENE'S obligation to pay MONSANTO the amounts described in
Subsection 6.1(b) shall begin in the marketing year in which CALGENE makes
COMMERCIAL SALES of cotton seed containing a THIRD-PARTY LEPIDOPTERAN-ACTIVE

          -----------------------------                                   
license under the LICENSED PATENT RIGHTS and MONSANTO TECHNOLOGY to a third
party having substantially the same scope as a LICENSE conveyed under this
Agreement and having terms which are more favorable as to earned royalty than
the terms granted to CALGENE hereunder and CALGENE is not selling in THE
TERRITORY any cotton seed which contains a THIRD-PARTY LEPIDOPTERAN-ACTIVE GENE,
then MONSANTO shall advise CALGENE as to such more favorable earned royalty
terms. CALGENE shall be entitled upon notice to MONSANTO to have this Agreement
amended to substitute such earned royalty terms for the earned royalty terms of
this Agreement as of the date upon which such license containing the more
favorable earned royalty terms shall have become effective and such new earned
royalty terms shall be effective for so long
<PAGE>
 
as CALGENE is not selling in THE TERRITORY any cotton seed which contains a
THIRD-PARTY LEPIDOPTERAN-ACTIVE GENE.

consecutive years starting January 1, 1997, total annual royalty revenue to
MONSANTO from all of its licensees for use of LEPIDOPTERAN-ACTIVE MONSANTO
GENE(S) in cotton is less than MONSANTO'S total annual royalty due to third
parties under license agreements from those parties for their technology applied
to cotton.  MONSANTO shall notify CALGENE when annual royalty revenue to
MONSANTO from all of its licensees within THE TERRITORY is less than one hundred
twenty-five percent (125%) of MONSANTO'S total annual royalty due to said third
parties.  In the event that MONSANTO elects to terminate this Agreement under
this Subsection 10.2(c), MONSANTO shall: (i) terminate also all license
agreements for the use of LEPIDOPTERAN-ACTIVE MONSANTO GENE(S) with other
licensees/sublicensees; and (ii) allow CALGENE and other sublicensees/licensees
to sell only existing inventories of cotton seed containing LEPIDOPTERAN-ACTIVE
MONSANTO GENE(S) in their possession as of the date of notice of termination or
for which each is then obligated by contract to take delivery.  In the event
that  MONSANTO so elects to terminate this Agreement under this Subsection
10.2(c) all other provisions of this Agreement shall remain in force until
contractual purchase commitments are fulfilled, and such inventories are
exhausted.  In the event that MONSANTO subsequently elects to re-enter the
cotton seed market with LEPIDOPTERAN-ACTIVE MONSANTO GENE(S), MONSANTO shall
offer a license to CALGENE under the same terms contained in this Agreement.

          (c)  CALGENE shall have the right, within three (3) months thereafter,
to terminate this Agreement by written notice to MONSANTO, if:

          (i)  within one (1) year of the date on which a party other than
          MONSANTO or CALGENE obtains GOVERNMENT APPROVAL of a THIRD-PARTY
          LEPIDOPTERAN-ACTIVE GENE which exhibits COMMERCIAL INSECT RESISTANCE,
          MONSANTO has not:

               (1)  authorized for COMMERCIAL DEVELOPMENT (and delivered to
               CALGENE seed containing) a LEPIDOPTERAN-ACTIVE MONSANTO GENE that
               results in plants of at least one (1) CALGENE CULTIVAR which
               exhibits the criteria for COMMERCIAL INSECT RESISTANCE, and all
               of the
<PAGE>
 
               AGRONOMIC CRITERIA in field tests conducted by CALGENE for two
               (2)  generations of testing at the BC\\3\\F\\3\\ level (or
               equivalent); and

               (2)  obtained GOVERNMENT APPROVAL of such LEPIDOPTERAN-ACTIVE
               MONSANTO GENE; and

               (3)  authorized the COMMERCIAL SALE of seed of one or more
               CALGENE CULTIVAR(S) containing such LEPIDOPTERAN-ACTIVE MONSANTO
               GENE subject to the homozygosity standard of Subsection 11.2; or

         (ii)  Cotton plants grown from seed containing one or more 
         LEPIDOPTERAN-ACTIVE MONSANTO GENE(S) which MONSANTO has authorized for
         COMMERCIAL SALE by CALGENE have ceased to exhibit COMMERCIAL INSECT
         RESISTANCE to one or more economically significant species of
         LEPIDOPTERAN INSECTS in tests conducted by CALGENE, and if, within one
         (1) year of such event, MONSANTO has not:

               (1)  authorized for COMMERCIAL DEVELOPMENT (and delivered to
               CALGENE seed containing) at least one (1) or more other
               LEPIDOPTERAN-ACTIVE MONSANTO GENE(S) that result in plants of at
               least one CALGENE CULTIVAR which, at that time, exhibits the
               criteria for COMMERCIAL INSECT RESISTANCE, and all of the
               AGRONOMIC CRITERIA in field tests conducted by CALGENE for two
               (2)  generations of testing at the BC\\3\\F\\3\\ level (or
               equivalent); and

               (2)  obtained GOVERNMENT APPROVAL for such LEPIDOPTERAN-ACTIVE
               MONSANTO GENE(S); and

               (3)  authorized the COMMERCIAL SALE of seed of one or more
               CALGENE CULTIVAR(S) containing such LEPIDOPTERAN-ACTIVE MONSANTO
               GENE subject to the homozygosity standard of Subsection 11.2. 

          (d)  After October 11, 2008, CALGENE shall have the right to terminate
this Agreement for any reason deemed sufficient to CALGENE by giving at least
three (3) months notice to MONSANTO.

     10.3 BREACH OF OBLIGATIONS:  Breach by any party of any of the material
          ---------------------                                             
provisions of this Agreement (other than the confidentiality obligations of
Section 8 or default upon any of the payment obligations provided herein) shall
entitle each of the other parties to give the party in breach or default at
least ninety (90) days' notice to cure such breach or default.  If a breach or
default by the defaulting party is not cured within the ninety (90) day period,
the materially-affected other party may terminate this Agreement by giving
notice to the other parties to take effect immediately.  Provided, however, that
if a breach or default is not cured by MONSANTO within the ninety (90) day
period, CALGENE, to the extent that it shall have been materially affected by
such default, may at its option by giving notice to MONSANTO (i) terminate this
Agreement, or (ii) terminate CALGENE'S obligations under Subsection 4.4, with
all other provisions of this Agreement to remain in effect.  Such option
selected by CALGENE shall take effect immediately.  Any termination under this
Subsection 10.3 shall not affect any other rights the notifying party may have
under this Agreement.

     10.4 DEFAULT ON PAYMENT:  In the event CALGENE or MONSANTO defaults on any
          ------------------                                                   
payment due the other party pursuant to Section 6 and fails to cure such default
within thirty (30) days of notice by CALGENE or MONSANTO, as the case may be,
the non-defaulting party shall have the right to terminate this Agreement by
giving notice to the other parties.

     10.5 EFFECT OF TERMINATION:  In the event this Agreement is terminated in
          ---------------------                                               
its entirety by either CALGENE or MONSANTO, CALGENE shall lose all rights and
LICENSES granted to it pursuant to this Agreement.  Provided, however, that if
this Agreement is terminated by CALGENE on account of a breach or default by
MONSANTO, CALGENE shall have the right to sell LICENSED COMMERCIAL SEED then in
the possession of CALGENE or which CALGENE is then obligated by contract to take
delivery.

     10.6 SURVIVAL OF COVENANTS:  Notwithstanding the termination of this
          ---------------------                                          
Agreement by notice or otherwise, the rights and obligations conferred by
Sections 6, 7, 8 and 11, 12, 13 and 14 with respect to events which occurred
prior to such termination and Subsection 15.15 shall survive termination.
<PAGE>
 
     10.7 ABANDONMENT OF GROWER LICENSING BY MONSANTO:
          ------------------------------------------- 

          (a) If on or after December 31, 1996, MONSANTO has any licensee to its
INSECT RESISTANCE cotton technology covered by this Agreement that is solely
authorized to solely grant the necessary license(s) to the cotton grower as part
of the purchase of cotton seed containing such technology, MONSANTO shall so
notify CALGENE.

          (b) Upon receipt of such notice, CALGENE shall, upon written request
of MONSANTO, be permitted to supersede this Agreement with the then prevailing
license agreement between MONSANTO and such other licensees of such MONSANTO
TECHNOLOGY. 

                       SECTION 11 -- WARRANTY/LIMITATIONS
                       ----------------------------------

          11.1 MONSANTO WARRANTIES:  MONSANTO hereby warrants and represents
               -------------------                                          
that:

          (a)  With respect to each LEPIDOPTERAN-ACTIVE MONSANTO GENE authorized
by MONSANTO for COMMERCIAL SALE, as of its DATE OF APPROVAL FOR COMMERCIAL SALE,
MONSANTO: (i) is the owner of such LEPIDOPTERAN-ACTIVE MONSANTO GENE and
MONSANTO TECHNOLOGY used in the development thereof;  (ii) is owner or licensee
of the LICENSED PATENT RIGHTS; and  (iii) has the right to license (or
sublicense) CALGENE such LEPIDOPTERAN-ACTIVE MONSANTO GENE and LICENSED PATENT
RIGHTS and MONSANTO TECHNOLOGY used in the development thereof for use under the
terms of this Agreement;

          (b)  With respect to each LEPIDOPTERAN-ACTIVE MONSANTO GENE authorized
by MONSANTO for COMMERCIAL SALE, as of its DATE OF APPROVAL FOR COMMERCIAL SALE,
there is no issued third-party United States patent, not then a part of the
LICENSED PATENT RIGHTS, of which MONSANTO is then aware, that will preclude
CALGENE'S lawful performance under this Agreement;

          (c)  As of the date on which MONSANTO gives the notice described in
Subsection 4.3(c) with respect to a LEPIDOPTERAN-ACTIVE MONSANTO GENE, official
clearances or written approvals for COMMERCIAL SALE of cotton seed containing
that LEPIDOPTERAN-ACTIVE MONSANTO GENE to produce genetically-transformed cotton
plants have been obtained from all federal government agencies which have
authority to regulate the production, use, and sale
<PAGE>
 
of such cotton seed or the plants produced therefrom.  Provided, however, that
this shall not require MONSANTO to obtain approval from any agency with respect
to the issuance of seed certificates or phytosanitary certificates or
certificates of plant variety protection under the Plant Variety Protection Act,
which approvals, when appropriate or required, shall be the responsibility of
CALGENE; and

          (d)  All material information that MONSANTO has provided or hereafter
provides to any federal government agency for the purpose of obtaining approval
of the COMMERCIAL SALE of LICENSED COMMERCIAL SEED is, to the best of MONSANTO'S
knowledge and belief, true and correct in all material respects.  Provided,
however, that this warranty is not made to CALGENE with respect to any such
information which was supplied to MONSANTO by CALGENE and which was thereafter
provided in the same form by MONSANTO to a governmental agency.

     11.2 CALGENE WARRANTY:  CALGENE hereby warrants and represents that CALGENE
          ----------------                                                      
shall not sell LICENSED COMMERCIAL SEED that fails to meet the homozygosity
standards for the respective LEPIDOPTERAN-ACTIVE MONSANTO GENE or LICENSED
CALGENE GENE, as the case may be, as set forth in Exhibit D.  CALGENE shall keep
lot samples of all LICENSE COMMERCIAL SEED sold by CALGENE  for at least two (2)
years following the date of sale of such LICENSED COMMERCIAL SEED following a
procedure for archiving and storage of samples of seed lots reasonably
acceptable to MONSANTO.

     11.3 MUTUAL WARRANTIES:  CALGENE and MONSANTO each warrant to the other
          -----------------                                                 
parties that this Agreement does not, and performance by CALGENE and MONSANTO of
their obligations hereunder will not, contravene any provision of any agreement
or contract binding upon either  CALGENE or MONSANTO.

     11.4 NO OTHER WARRANTIES:  It is expressly understood that CALGENE and
          -------------------                                              
MONSANTO MAKE NO REPRESENTATIONS, EXTEND NO WARRANTIES, EITHER EXPRESS OR
IMPLIED, AND ASSUME NO RESPONSIBILITIES, OTHER THAN EXPRESSLY PROVIDED FOR
HEREIN, WITH RESPECT TO:

          (a)  THE PERFORMANCE, MERCHANTABILITY OR FITNESS FOR A PARTICULAR
PURPOSE OF THE LICENSED CALGENE GENE,LEPIDOPTERAN-ACTIVE MONSANTO GENE(S),
MONSANTO TECHNOLOGY, LICENSED COMMERCIAL SEED, OR CALGENE B.T. CULTIVARS;
<PAGE>
 
          (b)  THE SCOPE OR VALIDITY OF ANY PATENT OF THE LICENSED PATENT
RIGHTS; OR

          (c)  LICENSED CALGENE GENE,LEPIDOPTERAN-ACTIVE MONSANTO GENE(S),
MONSANTO TECHNOLOGY, LICENSED COMMERCIAL SEED, OR CALGENE B.T. CULTIVARS OR USE
THEREOF BEING FREE FROM INFRINGEMENT OF PATENTS OTHER THAN LICENSED PATENT
RIGHTS.

                       SECTION 12 -- PATENT INFRINGEMENT
                       ---------------------------------

     12.1 UTILIZATION OF NON-INFRINGING TECHNOLOGY:  If, in MONSANTO'S opinion,
          ----------------------------------------                             
the development, production, processing, use, export or sale of LICENSED
COMMERCIAL SEED containing a LEPIDOPTERAN-ACTIVE MONSANTO GENE, that has been
authorized for COMMERCIAL SALE in writing by MONSANTO, would infringe a third
party patent, MONSANTO shall employ reasonable business efforts and judgment to
access the necessary license from said third party at no additional cost to
CALGENE, at which time said patent shall become part of the LICENSED PATENT
RIGHTS.  If MONSANTO cannot access said license at a reasonable cost, then
MONSANTO may require CALGENE to promptly cease sales and lawfully dispose of
such LICENSED COMMERCIAL SEED then in inventory, subject to the provisions of
Subsection 12.3.  If MONSANTO has alternative TECHNOLOGY which MONSANTO can
lawfully license for use by CALGENE that obviates the need for said third party
license which MONSANTO cannot access at a reasonable cost and results in plants
which exhibit the AGRONOMIC CRITERIA and COMMERCIAL INSECT RESISTANCE at the
same or greater levels as those CALGENE B.T. CULTIVARS produced from such
LICENSED COMMERCIAL SEED containing previously authorized TECHNOLOGY, MONSANTO
shall make such alternative TECHNOLOGY available to CALGENE.  CALGENE shall
promptly utilize such alternative TECHNOLOGY to avoid the need for such third
party license.  If CALGENE converts to such non-infringing alternative
TECHNOLOGY and has inventory of any such LICENSED COMMERCIAL SEED, which is not
salable in THE TERRITORY, MONSANTO shall reimburse CALGENE for the variable
costs of such inventory which CALGENE has either actually incurred or is bound
by contract to incur thereafter (The elements of variable costs of inventory
reimbursable hereunder to be determined using generally acceptable accounting
practices reasonably acceptable to MONSANTO.), plus CALGENE'S LOST PROFIT
CONTRIBUTION with respect to such inventory as defined in Subsection 12.3(b).
CALGENE shall make all reasonable
<PAGE>
 
efforts to limit or mitigate such costs.  Nothing in this Agreement shall
preclude CALGENE from negotiating directly with any third party for rights under
patents or patent applications held by a third party.  Provided, however, that
any costs incurred by CALGENE in negotiating for or acquiring any third party
patent rights shall not be credited against any payments due by CALGENE or added
to any payments due to CALGENE by MONSANTO unless MONSANTO agrees to such credit
or payment in writing.

     12.2 DEFENSE OF INFRINGEMENT CLAIMS:
          ------------------------------ 

          (a)  MONSANTO shall assume the defense of any claim brought against
CALGENE for infringement of any United States patent insofar as such claim
arises out of (i) CALGENE'S use of any LEPIDOPTERAN-ACTIVE MONSANTO GENE that
has been furnished by MONSANTO to CALGENE for initial evaluation or testing
prior to the DATE OF APPROVAL FOR COMMERCIAL DEVELOPMENT or of any LEPIDOPTERAN-
ACTIVE MONSANTO GENE that has been authorized by MONSANTO for COMMERCIAL
DEVELOPMENT or (ii) CALGENE'S development, production, use, or sale of LICENSED
COMMERCIAL SEED containing a LEPIDOPTERAN-ACTIVE MONSANTO GENE that has been
authorized by MONSANTO for COMMERCIAL SALE.  In any such suit, MONSANTO shall
indemnify CALGENE against any and all monetary damages and/or costs actually
awarded in such suit or any amounts paid in settlement in respect to such a
claim, subject to the conditions of Subsection 12.2(b).

          (b)  The obligation of MONSANTO pursuant to Subsection 12.2(a) above
shall apply only if:

          (1)  CALGENE promptly notifies MONSANTO of any claim within the scope
               of Subsection 12.2(a);

          (2)  MONSANTO is given exclusive control of the defense of such claim
               and all negotiations relating to its settlement;

          (3)  CALGENE promptly assists MONSANTO to the extent reasonably
               necessary for the conduct of the suit;

          (4)  Pursuant to the terms of Subsection 12.1 above, CALGENE promptly
               introduces alternative TECHNOLOGY provided by MONSANTO into
               CALGENE'S breeding and multiplication processes to abate the
               alleged infringement, as rapidly as possible, if the utilization
               of such TECHNOLOGY is commercially feasible.  Provided, however,
               that nothing in this Subsection
<PAGE>
 
               12.2(b)(4) shall be deemed to require CALGENE to infringe a third
               party patent or to undertake or continue any activity unless
               CALGENE has a good faith belief, based on opinion of counsel,
               that such activity would not infringe a valid and enforceable
               patent of another but, in such a case, if CALGENE refuses to
               introduce the alternative TECHNOLOGY, then MONSANTO may terminate
               this Agreement; and

          (5)  CALGENE shall take every reasonable measure requested by MONSANTO
               to mitigate patent infringement damages or, if such is not
               possible, promptly cease production, use and sales of LICENSED
               COMMERCIAL SEED described in MONSANTO'S request, and lawfully
               dispose of any LICENSED COMMERCIAL SEED then in inventory,
               subject to the provisions of Subsection 12.3.

     12.3 INDEMNITY AGAINST LOSSES DUE TO CLAIMS OF PATENT INFRINGEMENT:
          ------------------------------------------------------------- 

          (a)  In the event that CALGENE ceases sales of all or some types of
LICENSED COMMERCIAL SEED containing a LEPIDOPTERAN-ACTIVE MONSANTO GENE as
planting seed, either at MONSANTO'S request or upon the order of any court as a
result of a third party claim of infringement of a United States patent unless
such court order is the result of some act for which CALGENE is solely
responsible, MONSANTO shall reimburse CALGENE for an amount which allows CALGENE
to recover the variable costs of inventory of such LICENSED COMMERCIAL SEED not
sold on account of such event, which CALGENE has either actually incurred or is
bound by contract to incur thereafter less the amount which CALGENE has
recovered, or with reasonable efforts could have recovered, to mitigate such
costs. The elements of variable costs of inventory reimbursable hereunder  are
to be determined using generally acceptable accounting practices reasonably
acceptable to MONSANTO.  CALGENE shall deliver to MONSANTO an invoice for such
costs, which shall be issued after CALGENE has made commercially reasonable
efforts to limit or mitigate such costs.  Payment of such costs shall be due on
the earlier of ninety (90) days after delivery of such invoice, or on September
1 following the delivery of such invoice.  Provided, however, that any provision
hereof notwithstanding if, as of September 1 following the date on which CALGENE
has ceased sales of such LICENSED COMMERCIAL SEED  under the conditions of this
Subsection 12.3(a), CALGENE has not completely disposed of the inventory of such
LICENSED COMMERCIAL SEED, not sold as planting seed on account of such event
(including such seed returned by
<PAGE>
 
distributors), MONSANTO shall on that date, after receipt of an accounting for
such inventory then on hand, pay to CALGENE the variable costs of such
inventory, plus the net amounts due to CALGENE for LICENSED COMMERCIAL SEED
previously disposed of under the terms of this Subsection 12.3(a).  Provided,
further, that upon such payment CALGENE shall continue to attempt to lawfully
dispose of the remaining portion of such inventory of LICENSED COMMERCIAL SEED
using all commercially reasonable efforts suggested by MONSANTO which may
include blending seed or sale in a permitted foreign country, with MONSANTO
receiving the net proceeds after deduction of the direct costs of disposition.

          (b)  In addition to the variable costs of such inventory, in
circumstances covered by Subsection 12.3(a), MONSANTO shall reimburse CALGENE
for its LOST PROFIT CONTRIBUTION for any inventory which is not sold as planting
seed.  The LOST PROFIT CONTRIBUTION due to CALGENE shall be an amount calculated
by multiplying the quantity of LICENSED COMMERCIAL SEED expressed in UNITS then
in existence in CALGENE'S possession or for which CALGENE is contractually
liable to take possession, whether unconditioned, partially conditioned or fully
conditioned, which CALGENE is prevented from selling, times the LOST PROFIT
CONTRIBUTION (per UNIT) to be determined as follows:

     CALGENE'S average published distributor price for all CALGENE CULTIVARS
     (weighted by UNIT sales) for the marketing year in which such sales are
     prevented or if such prohibition or restriction occurs before the prices
     for the subject marketing year are published, then for the immediately
     preceding marketing year [said average published distributor price, for the
     purpose of this calculation, cannot have increased on a percentage basis,
     more than the weighted average amount of CALGENE'S year-to-year price
     increase for all CALGENE CULTIVARS over the prior three (3) year period].
     For example, if sales are stopped during marketing year 1998 and the
     weighted average price increases for all CALGENE CULTIVARS in 1995-1997
     averaged 5% per year, then the maximum that the weighted averaged published
     distributor price for all CALGENE CULTIVARS for 1998 can have increased
     over the 1997 price for the purpose of this calculation shall be 5%,

                                     Minus

     All distributor discounts (which for this calculation shall be consistent
     with comparative discounts available in prior years), on a per UNIT basis,
     all CALGENE
<PAGE>
 
     CULTIVARS, combined in a manner that equals the maximum discount actually
     given by CALGENE to any distributor for the subject marketing year,
   
                                    Equals

     per UNIT weighted average net distributor price for all CALGENE CULTIVARS,

                                    Minus

     CALGENE'S average per UNIT cost of goods (including variable and allocated
     fixed costs) for the current year for all CALGENE CULTIVARS as calculated
     using CALGENE'S historic costing methods, determined in accordance with
     generally accepted accounting principles, consistently applied, as verified
     by an independent certified public accounting firm reasonably acceptable to
     both CALGENE and MONSANTO,

                                    Equals

     LOST PROFIT CONTRIBUTION (per UNIT).

The amount owed by MONSANTO to CALGENE for such LOST PROFIT CONTRIBUTION shall
be reduced by any unincurred expenses and any specific reductions in CALGENE'S
expenses related to sales, marketing, research, quality assurance, general and
administrative, and interest which are a direct result of CALGENE not having
such LICENSED COMMERCIAL SEED inventory available for sale.  If after CALGENE
ceases the sales of such LICENSED COMMERCIAL SEED in circumstances covered by
Subsection 12.3(a), CALGENE'S sales of all CALGENE CULTIVARS for the subject
marketing year increase beyond the volume of sales of NON-B.T. COTTON SEED that
was forecast by CALGENE'S latest business plan developed prior to planting in
the spring of the year prior to the subject marketing year and before CALGENE
had notice that sales of LICENSED COMMERCIAL SEED would be ceased, then the
number of UNITS of LICENSED COMMERCIAL SEED for which MONSANTO is obligated to
compensate CALGENE for LOST PROFIT CONTRIBUTION shall be further reduced by the
number of UNITS of all CALGENE CULTIVARS sold by CALGENE in the subject
marketing year above the number forecast.

          (c)  MONSANTO'S obligations to reimburse CALGENE for the variable cost
of inventory and LOST PROFIT CONTRIBUTION under this Subsection 12.3 shall be
limited to a quantity of LICENSED COMMERCIAL SEED containing a LEPIDOPTERAN-
ACTIVE MONSANTO GENE mutually agreed by the parties.  Should the parties fail to
agree on this quantity by January 31 of the production year immediately
preceding the subject marketing year, MONSANTO'S
<PAGE>
 
obligations under this Subsection 12.3 for the subject marketing year shall be
limited to the quantity of LICENSED COMMERCIAL SEED sold by CALGENE during the
marketing year immedi ately preceding the subject marketing year.

          (d)  In the event that prevention of the sale of any UNIT of cotton
seed may qualify for  reimbursement of variable costs and LOST PROFIT
CONTRIBUTION under both this Agreement and any other license agreement between
the parties, MONSANTO shall be obligated to reimburse CALGENE only once for the
subject UNIT of cotton seed.

     12.4 SUSPECTED INFRINGEMENT OF LICENSED PATENT RIGHTS:  In the event
          ------------------------------------------------               
CALGENE learns of suspected infringement of LICENSED PATENT RIGHTS, then to the
extent that CALGENE is lawfully permitted to do so, CALGENE shall notify
MONSANTO to such effect and provide MONSANTO with the evidence concerning
suspected infringement in CALGENE'S possession. MONSANTO and CALGENE shall use
reasonable efforts to terminate such infringement without litigation.  Nothing
herein shall be construed as conferring on CALGENE any right to bring suit for
infringement of LICENSED PATENT RIGHTS.

     12.5 EFFECT OF INVALIDITY OF LICENSED PATENT RIGHTS:  In the event any
          ----------------------------------------------                   
claim of LICENSED PATENT RIGHTS is declared invalid or unenforceable by a final
judgment of a court having competent jurisdiction, the LICENSE granted under
Section 3 shall terminate and have no force or effect as to the subject matter
covered by that claim.  However, subject to the provisions of Section 6, the
LICENSE shall continue with respect to any remaining patent claims within
LICENSED PATENT RIGHTS.

     12.6 SUSPECTED MISAPPROPRIATION OF A POTENTIAL LEPIDOPTERAN-ACTIVE MONSANTO

party of a gene which is a candidate to become a LEPIDOPTERAN-ACTIVE MONSANTO
GENE or other MONSANTO TECHNOLOGY, furnished by MONSANTO, or progeny thereof, to
the extent that it may lawfully do so, CALGENE shall notify MONSANTO and provide
MONSANTO with the available information concerning the suspected
misappropriation, and cooperate with MONSANTO to terminate such misappropriation
and/or obtain redress therefor, but at the expense of MONSANTO.

     12.7  LIMITATION OF LIABILITY:  Except to the extent that CALGENE has a
           -----------------------                                          
claim against MONSANTO for breach of any of the warranties contained in
Subsections 11.1(a) and 11.1(b) [other than a claim with respect to its
inventories which are covered solely by the provisions of Subsections 12.3(a)
and 12.3(b)], the foregoing Subsections of this Section 12 state the entire
liability of MONSANTO to CALGENE in respect to any claim of patent infringement
in respect to CALGENE'S use of LEPIDOPTERAN-ACTIVE MONSANTO GENE(S) and MONSANTO
TECHNOLOGY in the commercialization of LICENSED COMMERCIAL SEED.  With respect
to a claim by CALGENE against MONSANTO for breach of any of the warranties
contained in Subsections 11.1(a) and 11.1(b), MONSANTO'S total liability for any
and all losses and damages arising out of any cause (whether such cause be based
in contract, negligence, other tort or otherwise, except for causes of action
based on MONSANTO'S fraudulent conduct) shall in no event exceed the net revenue
obtained by MONSANTO under this Agreement to the date of award of such damages,
reduced by an amount equal to any amounts paid by MONSANTO to CALGENE under
Subsections 12.3(a) and 12.3(b) hereof.  CALGENE shall take the measures
required by this Section 12 to mitigate patent infringement damages.

                      SECTION 13 -- CLAIMS BY VENDEES FOR
                      -----------------------------------
                          FAILURE OF GENE PERFORMANCE
                          ---------------------------

     13.1 INDEMNITIES FOR VENDEE CLAIMS:
          ----------------------------- 
          (a)  If MONSANTO authorizes COMMERCIAL SALE by CALGENE of LICENSED
COMMERCIAL SEED containing a LEPIDOPTERAN-ACTIVE MONSANTO GENE in THE TERRITORY,
then notwithstanding any other provisions of this Agreement, but subject to the
conditions and limitations of this Subsection 13.1 and Subsection 13.2, MONSANTO
and CALGENE shall each indemnify the other, so that each shall share on the pro
rata basis set forth in Subsection 13.1(b), for the costs of any claims
(including reasonable costs of defense) by cotton farmers who purchase LICENSED
COMMERCIAL SEED containing a LEPIDOPTERAN-ACTIVE MONSANTO GENE and of
distributors against whom such farmers may make claims arising from (1) any
alleged breach of an express warranty relating to failure of performance of the
INSECT RESISTANCE TRAIT and (2) any alleged breach of implied warranties of
merchantability or fitness for a particular purpose relating to failure of
performance of the INSECT RESISTANCE TRAIT when disclaimers of such express or
<PAGE>
 
implied warranties set forth on the packaging containing the subject LICENSED
COMMERCIAL SEED and the invoices pertaining thereto are not effective to prevent
such claims being asserted and won by such farmers.  It is understood and agreed
that MONSANTO shall be free to give any performance warranty that it wishes.
Provided, however, that before there is an obligation by CALGENE to indemnify
MONSANTO by sharing in the costs of such claims on said pro rata basis, the
parties must have reached a written agreement on the content, scope, limitation
and necessary conditions of any express performance warranty given by MONSANTO,
claims for the breach of which would be subject to this indemnification.
MONSANTO and CALGENE shall each act in good faith to reach agreement on
appropriate express performance warranties by the DATE OF APPROVAL FOR
COMMERCIAL SALE.  If MONSANTO and CALGENE have not reached agreement on the
content, scope, limitation or necessary conditions of such express performance
warranties by the DATE OF APPROVAL FOR COMMERCIAL SALE, MONSANTO shall designate
the content, scope, limitation and necessary conditions for express performance
warranties which would be subject to this indemnification.  Such express
warranties shall be made solely by MONSANTO.

          (b)  The costs of claims covered under Subsection 13.1(a) shall be
prorated between the parties on the basis of MONSANTO'S and CALGENE'S respective
share of the NET LICENSE REVENUE obtained from licensing cotton farmers the use
of the LICENSED COMMERCIAL SEED.  In the event that any claim is settled in
whole or in part by furnishing replacement seed, the cost of settlement shall be
based upon the full costs of such seed per UNIT determined in accordance with
generally accepted accounting principles.

          (c)  In the event that a claim is asserted against CALGENE covered by
Subsection 13.1(a), CALGENE shall give prompt notice to MONSANTO and MONSANTO
shall have the right, at its election, to take over the defense or settlement of
such claim by giving notice to CALGENE.  CALGENE shall have the right to
participate at its own expense.  The parties shall cooperate fully in defending
any such claim.

          (d)  In the event that information comes to the attention of either
MONSANTO or CALGENE that a change in conditions has occurred which reasonably
necessitates a modification of performance warranty(ies) previously approved or
designated by MONSANTO, as provided in Subsection 13.1(a), the party having such
information shall notify the other party within sixty (60) days after receipt of
such information and MONSANTO and CALGENE shall each act in good faith to reach
agreement upon appropriate modification(s) of such performance warranty(ies).
If, within thirty (30) days after written notice requesting modification(s) in
the performance warranty(ies) is
<PAGE>
 
given, the parties have not agreed upon the necessity for or the form of such
modification(s), MONSANTO shall determine whether changed circumstances
necessitate modification(s) of the performance warranty(ies) and, if so, shall
designate the appropriate modification(s).

          (e)  In the event information which has been reasonably verified comes
to either MONSANTO'S or CALGENE'S attention any time after the approval or
designation of the express performance warranty(ies) which at the time of its
receipt and verification would be reasonably convincing to an expert in the
relevant field that the express performance warranty(ies) should be modified,
and the party with such information does not notify the other party of such
information within sixty (60) days thereafter, then the party withholding such
information shall be solely liable for the costs of all such claims arising from
the alleged breach of such express performance warranty(ies) in connection with
sales occurring between (1) the date on which CALGENE in the exercise of
reasonable commercial diligence could have disseminated effective legally-
binding modification(s) of such express performance warranty(ies) had such
information been known to it and (2) the date on which CALGENE does, or in the
exercise of reasonable commercial diligence could, disseminate effective
legally-binding modification(s) of such performance warranty(ies), and the party
withholding such information shall indemnify and hold the other party harmless
from and against any and all damages or other liabilities arising from such
claims and for any extra expenses arising from its delay in notifying the other
party of such information.

     13.2 CALGENE'S INDEMNITY FOR VENDEES CLAIMS:
          ---------------------------------------

          (A)  NOTWITHSTANDING THE PROVISIONS OF SUBSECTION 13.1, CALGENE SHALL
DEFEND AND INDEMNIFY AGAINST, AND HOLD MONSANTO AND THEIR RESPECTIVE EMPLOYEES,
DIRECTORS, OFFICERS AND AGENTS HARMLESS FROM, ANY LOSS, COST, LIABILITY OR
EXPENSE (INCLUDING COURT COSTS AND REASONABLE FEES OF ATTORNEYS AND OTHER
PROFESSIONALS) INCURRED FROM ANY CLAIM BY COTTON FARMERS WHO PURCHASE LICENSED
COMMERCIAL SEED, AND OF DISTRIBUTORS AGAINST WHOM SUCH FARMERS MAY MAKE CLAIMS,
ARISING OR ALLEGED TO ARISE OUT OF THE FAILURE PLANTS GROWN FROM LICENSED
COMMERCIAL SEED OF CALGENE B.T. CULTIVARS  SOLD BY CALGENE TO EXHIBIT INSECT
RESISTANCE, IF SUCH LICENSED COMMERCIAL SEED DOES NOT CONTAIN A LEPIDOPTERAN-
ACTIVE MONSANTO GENE, OR SUCH LICENSED COMMERCIAL SEED AT THE TIME IT WAS
SHIPPED BY CALGENE, FAILS TO MEET THE HOMOZYGOSITY STANDARD FOR THE RESPECTIVE
LEPIDOPTERAN-ACTIVE MONSANTO GENE, AS THE CASE MAY BE, AS
<PAGE>
 
SET FORTH IN SUBSECTION 11.2. PROVIDED, HOWEVER, THAT: (I)CALGENE SHALL HAVE
SOLE CONTROL OF SUCH DEFENSE, AND (II) MONSANTO SHALL PROVIDE NOTICE TO CALGENE
OF ANY SUCH CLAIM WITHIN TWENTY (20) DAYS AFTER MONSANTO BECOMES AWARE OF IT.

          (b)  In order for a claim to come within the coverage of Subsection
13.2(a) if such LICENSED COMMERCIAL SEED contains a LEPIDOPTERAN-ACTIVE MONSANTO
GENE, MONSANTO must show based on tests of lot samples from which the subject
LICENSED COMMERCIAL SEED was drawn, that the subject lot samples did not meet
the homozygosity standards of Exhibit D.  If CALGENE does not have the correct
lot samples in its possession for analysis, then the tests shall be done on the
plants or plant material alleged to have been produced from the subject LICENSED
COMMERCIAL SEED and coverage of such claim under Subsection 13.2(a) based solely
thereon.

                        SECTION 14 -- GOVERNMENT ACTION
                        -------------------------------

     14.1 INDEMNITY FOR LOSSES DUE TO GOVERNMENT ACTION:  
          ---------------------------------------------               

          Except under circumstances to which Section 12 applies, if, subsequent
to the DATE OF GOVERNMENTAL APPROVAL, any federal or state court or government
agency cancels a registration or otherwise takes some action which precludes the
sale of LICENSED COMMERCIAL SEED containing a LEPIDOPTERAN-ACTIVE MONSANTO GENE
for planting seed, MONSANTO and CALGENE shall jointly try to obtain approval
from such court or agency in order to sell the existing inventory of LICENSED
COMMERCIAL SEED containing a LEPIDOPTERAN-ACTIVE MONSANTO GENE for planting
seed. To the extent that, after commercially reasonable efforts to obtain such
approvals, and after the exercise of commercially reasonable efforts to mitigate
the losses by sale of such inventory for non-seed purposes in THE TERRITORY
and/or permitted sales for planting purposes outside THE TERRITORY on account of
such government action, any portion of existing inventories of LICENSED
COMMERCIAL SEED containing a LEPIDOPTERAN-ACTIVE MONSANTO GENE cannot be sold
for planting seed in THE TERRITORY, then MONSANTO shall reimburse CALGENE for
one-half (1/2) of its variable costs to produce the inventory of LICENSED
COMMERCIAL SEED containing a LEPIDOPTERAN-ACTIVE MONSANTO GENE not sold as
planting seed in THE TERRITORY on account of such government action, less one-
half (1/2) of any amounts received, if any, by CALGENE from the sale of such
inventory for non-seed purposes in THE TERRITORY and/or permitted sales for
planting purposes outside THE TERRITORY. The elements of variable costs of
<PAGE>
 
inventory reimbursable hereunder are to be determined using generally acceptable
accounting practices reasonably acceptable to MONSANTO.  CALGENE shall deliver
to MONSANTO an invoice for such costs.  Payment of such costs shall be due on
the earlier of ninety (90) days after delivery of such invoice, or on September
1 following the delivery of such invoice.  Provided, however, that if as of
September 1 following the date on which the above-described court or agency
orders were issued, CALGENE has not completely disposed of the inventory of such
LICENSED COMMERCIAL SEED containing a LEPIDOPTERAN-ACTIVE MONSANTO GENE not used
as planting seed in THE TERRITORY on account of such government action
(including such seed returned by distributors), MONSANTO shall on that date,
after receipt of an accounting for such inventory on hand, pay CALGENE one-half
(1/2) of the variable costs of such inventory then on hand, plus the net amounts
due to CALGENE for such LICENSED COMMERCIAL SEED containing a LEPIDOPTERAN-
ACTIVE MONSANTO GENE previously disposed of under the terms of this Subsection
14.1.  Provided, further, that upon such payment, CALGENE shall continue to
attempt to lawfully dispose of the re maining inventory of such LICENSED
COMMERCIAL SEED containing a LEPIDOPTERAN-ACTIVE MONSANTO GENE using all
commercially reasonable efforts suggested by MONSANTO, with MONSANTO receiving
one-half of the net proceeds after deduction of the direct costs of disposition.

<PAGE>
 
this Agreement), except with the prior written consent of CALGENE.  Provided,
however, that MONSANTO may assign this Agreement and the rights and obligations
thereunder to another acquiring all or substantially all of the assets related
to research and development in the field of cotton of MONSANTO'S Ceregen
Business Unit, or such other business unit of MONSANTO as may then be

canceled, renewed or extended, and the terms hereof may be waived, only by a
written instrument signed by all the parties, or, in the case of a waiver, by
the party or parties waiving compliance.  Except where a specific period for

exercising any right, power or privilege hereunder shall operate as a waiver
thereof.  Nor shall any waiver on the part of any party of any such right, power
or privilege, nor any single or partial exercise of any such right, power or
privilege, preclude any further exercise thereof or the exercise of any
subsequent or other such right, power or privilege.  Except as otherwise
provided herein, no conditions, usage of trade, course of dealing or

     15.14 DISPUTE RESOLUTION:
           ------------------ 

          (a)  Any claim, dispute, difference or controversy between the parties
not relating to issues involving patent rights arising out of, or relating to,
this Agreement which cannot be settled by mutual understanding between the
parties (a "Dispute") shall be submitted within thirty (30) days of such Dispute
to a panel consisting of a senior executive nominated by each party (the
"Panel").  Such Panel shall meet and use reasonable efforts to resolve said
Dispute.

          (b)  If the Dispute cannot be resolved within thirty (30) days of
submission to the Panel, then any party may invoke the following arbitration
rights:
               (1)  The Dispute shall be referred to arbitration under the rules
                    of the American Arbitration Association (AAA) to the extent
                    that such rules are not inconsistent with the provisions of
                    this Subsection 15.14.  Judgment upon the award of the
                    arbitrators may be entered in any court having jurisdiction
                    thereof or application may be made to such court for a
                    judicial confirmation of the award and an order of
                    enforcement, as the case may be.  The demand for arbitration
                    shall be made within a reasonable time after the Dispute in
                    question has arisen and, in any event, shall not be made
                    after the date when institution of legal or equitable
                    proceedings, based on such Dispute in question, would be
                    barred by the applicable statute of limitations;

               (2)  The independent arbitration panel shall consist of three (3)
                    independent arbitrators, one (1) of whom shall be appointed
                    by each party involved in the Dispute.  In the event that
                    one (1) party does not designate an arbitrator, the other
                    party may request the Executive Secretary of the AAA to
                    designate an arbitrator for such party.  The two (2)
                    arbitrators thus appointed shall choose the third arbitrator
                    so that the arbitration panel shall consist of three (3)
                    arbitrators; provided, however, that, if the arbitrators
                    selected by the
<PAGE>
 
                    parties involved in the Dispute are unable to agree on the
                    appointment of the additional arbitrator, any of the
                    selected arbitrators may petition the Executive Secretary of
                    the AAA to make the appointment of such additional
                    arbitrators; and

               (3)  The place of arbitration shall be Memphis, Tennessee.

          (c)  Pending resolution of any Dispute, each party involved in the
dispute shall make every reasonable effort to minimize adverse economic
consequences to the parties under this Agreement which would result from any
delays caused by attempts to resolve the Dispute.  Such reasonable effort shall
include, without limitation, continued performance of relevant obligations under
a reservation of rights in lieu of termination and nonperformance, and nothing
contained in this Subsection 15.14 shall serve to preclude any party from its
right to seek any other remedy at law.

     15.15 MODIFICATION OF RELATED AGREEMENTS:  The RELATED AGREEMENTS are
           ----------------------------------

                             HOMOZYGOSITY STANDARD
                             ---------------------

GENERAL
- - -------

*    This protocol primarily addresses outcrossing which is one potential source
of negatives.  Additional sources for negatives include mishandling of seed and
misclassification by ELISA.  Separate protocols will need to be developed to
address these areas.

*    When non-transgenic borders are required, keep them spatially separated
from the transgenic breeding material.  Always use a 4 row or 15' transgenic
border of a variety with the same gene/insert around nurseries.

*    Regularly spray the breeding nurseries and seed production fields with an
insecticide to control pollinating insects using weekly applications of Sevin
during flowering.

*    Harvest leaf samples at appropriate stage to ensure high quality material
for the ELISA.  Ideally, leaf samples should be pulled within 6 weeks after
planting.

*    Confirm purity for each generation on both seed and leaf tissue.

*    Cotton should be grown in fields with a minimal possibility for volunteer
cotton from the previous cropping season.

*    Outer eight rows of a production field should not be harvested for seed.
Additionally, the first 30 feet on the ends should be excluded from the seed
harvest if the bordering cotton is non-transgenic or is a different line.

SPECIFIC GUIDELINES

F1 and F2 generation
- - --------------------

*    Whenever possible, both the F1 and F2 plants are grown in the greenhouse to
eliminate the possibility of outcrossing.

*    If F1 and/or F2 plants are grown in the field, the seed harvested from
those plants must be from hand-selfed flowers.

*    Leaf samples of F1 and F2 plants will be tested with ELISA for the presence
of the gene.  All negative plants will be rogued to eliminate the possibility of
outcrossing.
<PAGE>
 
F3 generation
- - -------------

*    Ideally, progeny tests will be done on F2 plants prior to planting to
                                                      -----------------   
determine which F2 plants are homozygous for the gene(s) of interest.  F3 seed
from only homozygous F2 plants would then be planted in progeny rows in the
field.  Homozygosity is determined by testing 40 to 50 progeny per plant.

*    Progeny rows from  homozygous F2 plants of the same transgenic gene/insert
are grouped together.  A border of the same transgenic line, as described above,
must separate these progeny rows from other transgenic lines.

*    ELISA analyses must be completed prior to flowering. Rows which are
negative or segregating must be rogued prior to pollination to prevent
outcrossing.  Negative or segregating rows can be eliminated with herbicides or
hand hoeing.

*    Progeny rows should be harvested and maintained separately.

F4 generation
- - -------------

*    Confirm results on the F4 seed with ELISA analyses on 400 seed.    Advance
only those lines with no negative seed.  This provides 95% confidence that the
actual level of negatives is less than 1%.

*    Progeny rows must be planted as separate blocks in the F4 generation
(typically grown in the winter nursery).

*    Analyze 400 leaf samples from the progeny row blocks to confirm purity.
Rogue any that do not have 100% expressing plants.

*    Harvest of progeny row blocks is similar to F3 harvest described above.
The outer 4 rows should be discarded if the cotton bordering the progeny row
block is not a pure source of the same transgenic line.

*    Bulking across progeny rows done only after confirming transgenic purity of
F5 seed.
<PAGE>
 
F5 generation
- - -------------

*    Confirm seed purity by testing 1000 seed/family. Only families with purity
greater than 99% can be bulked for seed production. This provides 95% confidence
that the actual purity is greater than 98%.

*    Plant pure lots in seed production fields.

*    Analyze 1000 leaf samples per lot to confirm purity.

*    Do not include outer eight border rows and 30' of ends in seed harvest if
not bordered with same transgenic line.

*    Analyze 4000 seed samples per lot to confirm purity.  Do not advance or
sell if less than ninety eight percent (98%) pure.

                          SECOND AMENDED AND RESTATED
                             EMPLOYMENT AGREEMENT
                             --------------------

AGREEMENT made as of the 16th day of October, 1995 by and between 
Jeffrey D. Gargiulo ("Executive") and Gargiulo, L.P., a Delaware limited
partnership (the "Partnership") and sometimes referred to herein as the Employer
(the "Employer").

                             Preliminary Statement
                             ---------------------

     NTGargiulo, Inc., a Florida corporation ("NTG") and the Partnership, among
others, entered into an Asset Contribution Agreement dated December 23, 1992
(the "Asset Contribution Agreement"), pursuant to which NTG contributed
substantially all of its assets to the Partnership and the Partnership has
assumed substantially all of the liabilities of NTG.  Gargiulo G.P., Inc.
(formerly "N.T. Gargiulo G.P., Inc."), a Delaware corporation (the "Company"),
is the managing general partner of the Partnership.  For a period of continuous
years until December 23, 1992, the Executive had been employed as an executive
officer of NTG, which together with its affiliates, were at various times
engaged in the operation of packing houses and farms, in the marketing of fresh
fruits and vegetables, and in the provision of management services to others in
connection with those activities.

     In connection with the contribution of assets to the Partnership, the
parties entered into the Employment Agreement dated as of December 23, 1992
("Original Employment Agreement") pursuant to which the Executive continued to
render services as an executive employee of the Employer and covenanted not to
compete with the Employer.   Executive, Employer, Tomato Investment Associates,
Inc. ("MCO"), Monsanto Company ("Monsanto") and certain

                                       1
<PAGE>
 
other parties also entered into a Restructuring Agreement ("Restructuring
Agreement") and the parties hereto entered into an Amended and Restated
Employment Agreement dated as of July 29, 1994 as contemplated by such
Restructuring Agreement.  Also, concurrently therewith, the parties to the
Agreement entered into the Option and Retained Interests Agreement (the "Option
Agreement") pursuant to which MCO was granted, among other things, an option to
purchase certain additional interests in the Partnership (the term "Option" is
used herein as defined in such Option and Retained Interests Agreement).  It is
anticipated that (a) MCO will purchase all remaining Partnership interests it
does not currently hold (the "Additional Interest Acquisition"), (b) Monsanto
will contribute to a new corporation ("Holding Company") to be formed by
Monsanto and Calgene, Inc., a Delaware corporation ("Calgene"), all of the
capital stock of MCO in exchange for shares of Holding Company (the "Exchange"),
whereupon MCO will become a wholly owned subsidiary of Holding Company, (c)
simultaneously with the Exchange, a subsidiary of Holding Company will merge
with Calgene, whereupon Calgene will also become a wholly owned subsidiary of
Holding Company, and (d) immediately after the Exchange, the Company will
dissolve and liquidate and distribute all of its assets to MCO, as its sole
stockholder, whereupon the Partnership will be dissolved and all of its assets
and liabilities will be vested in MCO (the "Liquidation" and, collectively with
the Additional Interest Acquisition and the Exchange, the "Partnership
Reorganization Transactions").  However, this Agreement shall become effective
whether or not the Partnership Reorganization Transactions are consummated.
This Second Amended and Restated Employment Agreement amends, restates and
supersedes the Original Employment Agreement and the Amended and Restated
Employment Agreement in their entirety.  The Effective Date of the Second
Amended and Restated Employment Agreement shall be July 1, 1995.

     NOW THEREFORE, in consideration of the mutual promises herein contained,
and for other good and valuable consideration, the receipt and adequacy of which
are conclusively acknowledged, the parties hereto, intending to be legally
bound, hereby agree as follows:

     1.  The Employer shall continue to employ the Executive as Chief Executive
Officer of the Partnership.  It is understood and the Partnership agrees that
during the Employment Term (as hereinafter defined) the Executive shall also
serve, without additional compensation therefor, as the President and Chief
Executive Officer of the Company and, if and when elected, as an officer or
director of any subsidiary, division or other affiliates of the Employer,
provided that, as determined by the Company's Board of Directors, a portion of
the Executive's compensation under this Agreement may be allocated and charged
to the Company for services provided to it by the Executive.  Notwithstanding
the foregoing, if the Partnership Reorganization Transactions are consummated,
then (a) Executive shall become the Chief Executive Officer of MCO, (b) MCO
shall assume all of the obligations of the Partnership hereunder, (c) MCO shall
thereafter be deemed the "Employer" hereunder, and (d) this Agreement shall
otherwise remain in full force and effect.  Nothing in this provision shall
require the Executive, without his written consent, to assume significant
management duties with Holding Company or any Holding Company affiliate which is
unrelated to MCO and its subsidiaries.  The Executive accepts such employment
and agrees to perform diligently, on a full-time basis, and to the best of his
ability during the Employment Term, all of the duties and functions attendant
upon such offices and such other executive duties and functions appropriate to
such offices as may be assigned to him by the Company's Board of Directors or,
upon consummation of the Partnership Reorganization Transactions, by MCO's Board
of Directors.  The Executive shall be a member of and report solely to the Board
of Directors of the Company or, upon consummation of the

                                       3
<PAGE>
 
Partnership Reorganization Transactions, to the Board of Directors of MCO.  The
Employer shall provide, pay for, and maintain such facilities, equipment and
supplies as are reasonably necessary for the Executive's performance of his
duties under this Agreement.  The Executive shall, unless prevented by
incapacity, devote his whole working time, attention and ability to the
discharge of his duties hereunder and to the faithful and diligent performance
of such duties and the exercise of such powers.  The Executive shall perform his
duties and responsibilities pursuant to reasonable guidelines for employee
conduct applicable to all employees of the Employer and adopted by the Company's
Board of Directors (or, upon consummation of the Partnership Reorganization
Transactions, by MCO's Board of Directors) from time to time pertaining to
internal control, business conduct, conflicts of interest, outside business
activities and other similar issues.  The Executive agrees that, in addition to
complying with the provisions of Section 6 of this Agreement, he will not,
during the Employment Term, engage in any other gainful occupation or ventures,
except that the Executive may participate in such trade, community, charitable
and religious activities which do not interfere in a material respect with the
performance of his duties hereunder, and except that the Executive shall be
entitled to make and manage his personal investments, which include the
ownership of a vineyard in Napa Valley, California, provided that such
investments require only his incidental time, do not conflict with or compete
with his duties to the Employer hereunder (it being understood that the
Executive has ownership interests in lands which are leased to the Employer or
its affiliates, and such investments or the Executive's activities in respect
thereof shall not be deemed to constitute a conflict of interest with the
Executive's duties to the Employer hereunder), are not violative of the
provisions of Section 6 hereof, and are consistent with the guidelines for
employee conduct described previously in this Section 1.  If the Partnership
Reorganization Transactions are consummated, then the Executive shall become a
member of the Board of Directors of Holding Company, and Holding

                                       4
<PAGE>
 
Company shall provide the Executive with the same Director and Officer Liability
Insurance coverage it provides to the other members of the Board of Directors of
Holding Company and to the other directors and officers of the Employer. If the
Executive is elected or appointed as an officer of Holding Company, Holding
Company shall provide the Executive with the same Director and Officer Liability
Insurance Coverage it provides the other officers of Holding Company. If the
Partnership Reorganization Transactions are not consummated, Monsanto will make
any amendments necessary to the charter documents of MCO or any successor entity
so that the indemnification provisions shall be comparable to the
indemnification provisions of the charter documents of Monsanto and its
subsidiaries. The Executive acknowledges and agrees that, if the Partnership
Reorganization Transactions are consummated, then timely cooperation with
Holding Company shall be a material duty under this Agreement. In this regard,
the Executive agrees that he will use his best efforts so that he and the
Employer will provide timely financial reports, other communications and perform
other duties and obligations relating to the matters described in Schedule 1 as
may reasonably be required by Holding Company from time to time. The Executive
agrees that, contemporaneously with his execution of this Agreement, he will
execute a separate agreement relating to obligations of Gargiulo management to
cooperate, communicate and inform, the form of which is attached hereto as
Schedule 1 (the "Cooperation Agreement").

     2.   (a)  The initial term of the Executive's employment under this
Agreement shall be for a period commencing effective July 1, 1995 and ending on
December 31, 2001, unless sooner terminated pursuant to Section 2(b), Section 5,
Section 6 or Section 7 hereof.  The term of the Executive's employment hereunder
shall be automatically renewed from year to year after December 31, 2001, for
additional one-year periods, unless sooner terminated pursuant to Section 2(b),
Section 5, Section 6 or Section 7 hereof or unless at least six (6) months prior
to the expiration of the initial or

                                       5
<PAGE>
 
any renewal term, either party gives written notice to the other of his or its
intention not to renew the Executive's employment at the end of such term.  The
initial term of the Executive's employment (as it may be sooner terminated
pursuant to Section 2(b), Section 5, Section 6 or Section 7 hereof) is referred
to herein as the "Initial Term" and such Initial Term, as it may be renewed from
time to time, is referred to herein as the "Employment Term."

          (b)  Notwithstanding anything in Section 2(a) above, if, after
completion of the Employer's financial statements for the calendar year ending
December 31, 1998, the independent certified public accountants of the Company
determine that Cumulative EBIT (as defined in Schedule 2, a copy of which is
attached hereto and incorporated by reference herein) through December 31, 1998
is less than 70% of the Cumulative Plan, the Board of Directors of the Company
(or, if the Partnership Reorganization Transactions are consummated, the Board
of Directors of MCO) shall give the Executive notice of its determination, and
the Employer shall have the right to renegotiate this Agreement.  If the
renegotiation is not completed in a manner acceptable to the Board, in its sole
discretion, within sixty (60) days of the Board's notice to the Executive, the
Employer shall have the right to terminate this Agreement, in which case the
Executive's termination shall hereinafter sometimes be referred to as a "Section
2(b) Termination."  If the Partnership Reorganization Transactions are
consummated and the Board of Directors of Holding Company disputes the
determination that Cumulative EBIT through December 31, 1998 is 70% or more of
the Cumulative Plan, the dispute shall be referred to Holding Company's
independent certified public accountants ("Certified Public Accountants") for
that firm to determine, using generally accepted accounting principles, if
Cumulative EBIT through December 31, 1998 equalled or exceeded 70% of the
Cumulative Plan, and the Certified Public Accountants' determination shall be
final and binding on all parties absent manifest error.

                                       6

     3.   In consideration of the services rendered by the Executive pursuant to
this Agreement, the Employer agrees to provide the Executive compensation as
follows:

          (a)  Commencing on January 1, 1996 and continuing through December 31,
1996, the Employer shall pay the Executive an annual salary ("Salary") of Three
Hundred Fifty Thousand Dollars ($350,000), payable in substantially equal
monthly installments.  Commencing January 1, 1997 and annually thereafter during
the Initial Term, Executive's Salary shall be increased by an amount equal to
four percent (4%) of the Salary paid to the Executive during the immediately
preceding calendar year.

          (b)  In addition, during the Initial Term, the Executive shall be
eligible for Annual and Long-Term Incentive Awards as defined on Schedule 2.
The Long-Term Incentive Award shall be based on the performance of the Company
during calendar years 1996-2001.  No Long-Term Incentive Award shall be paid to
the Executive unless all of the goals and targets set forth on Schedules 2 and
2-A have been met as of the end of calendar year 2001.  The Executive
acknowledges and agrees that the financial targets, calculations and projections
on which the Long-Term Incentive Award is based were prepared using financial
information, data and projections prepared by the Company under the direction of
the Executive and furnished by the Company to Monsanto.  It is understood that
the Executive is not providing any assurance that the targets and goals set
forth on Schedules 2 and 2-A will in fact be met.

If the Partnership Reorganization Transactions are consummated and the Board of
Directors of Holding Company disputes whether the respective financial goals set
forth on Schedule 2 have been met, the dispute shall be referred to the
Certified Public Accountants for that firm to determine, using generally
accepted accounting principles, if the financial goals were, in fact, met.  The

                                       7
<PAGE>
 
Certified Public Accountants' determination shall be final and binding on all
parties absent manifest error.

          (c)  The Additional Compensation, as defined in the First Amended and
Restated Employment Agreement, for periods under prior agreements through June
30, 1995 shall be paid in accordance with the terms of the First Amended and
Restated Employment Agreement.

          (d)  The compensation (Salary and Annual and Long-Term Incentive
Awards) for any portion of the Employment Term after the Initial Term shall be
as mutually agreed by the Executive and the Board of Directors of the Company.

          (e)  Payments of any Annual or Long-Term Incentive Awards and any
incentive compensation payable pursuant to Section 3(d) for any fiscal year or
period shall be made no later than two and one-half months following the close
of the applicable calendar year.

          (f)  The Executive shall be accorded the right to participate, on a
basis comparable to the basis on which other executive officers of the Employer
participate (including the payment of any applicable employee contributions and
premiums), in any and all stock option plans, pension plans (provided his
participation in the pension plan will not adversely affect the tax qualified
status of the plan), group insurance, accident, sickness, disability and
hospitalization insurance plans and all other similar employee benefit plans
(but not including any nonqualified profit-sharing, bonus or other incentive
compensation plan (except for a stock option plan)) for the benefit of the
Employer's executive officers which may be in effect during the period of the
Executive's employment hereunder.  During the Employment Term and for a period
of twelve months after any termination thereof, the Employer shall at its own
expense maintain term life insurance on the Executive's life providing coverage
of at least $2,000,000 (provided that any cost thereof in excess of that
attributable to

                                       8
<PAGE>
 
normal rates shall be borne by the Executive), naming such beneficiaries as the
Executive may designate from time to time.  The Executive shall be entitled to
the same types of additional fringe benefits as the Executive was entitled to
receive in his capacity as Chief Executive Officer of the Partnership during the
year preceding the Effective Date of this Agreement to the extent such are
disclosed in Schedule 3 attached to this Agreement.  Any other fringe benefits
shall be as approved by the Board of Directors of the Company (or, if the
Partnership Reorganization Transactions are consummated, by the Board of
Directors of MCO).

     4.   The Executive is authorized to incur reasonable expenses, including
without limitation reasonable travel and entertainment expenses, incident to the
business of the Partnership and the Company (and, if the Partnership
Reorganization Transactions are consummated, to the business of MCO) and the
performance of his duties under this Agreement.  The Employer will reimburse the
Executive for all such expenses upon presentation by the Executive, from time to
time, of an itemized account of such expenses as well as supporting evidence
thereof.

     5.   (a)  The Executive shall be entitled to five (5) weeks of vacation
during each calendar year of the Employer, and to reasonable absences by reasons
of incapacity.  For purposes of this Agreement, "incapacity" shall mean
disability to perform the duties and functions assigned to the Executive
pursuant to Section 1 of this Agreement by reason of the Executive's then
physical or mental condition.  There shall be no reduction in the Executive's
Salary or in his entitlement to Annual or Long-Term Incentive Awards or
compensation pursuant to Section 3(d) for the first six (6) months of any
continuous period of incapacity.  In the event that the Executive's incapacity
continues for a period exceeding six (6) consecutive months, and without
abrogating the Employer's right not to renew the Employment Term pursuant to and
in accordance with the provisions of Section 2 of this Agreement, thereafter the
Executive

                                       9
<PAGE>
 
shall be entitled to receive two-thirds (2/3) of the Salary, and no Annual
Incentive Award, for so long as such incapacity continues, for a maximum period
of eighteen (18) months after such initial six (6) month period; provided,
however, that the Employer may terminate this Agreement at any time during the
last twelve (12) months of such eighteen (18) month period if the Executive
shall be certified at such time to be "incapacitated" (within the meaning of
"incapacity" set forth herein) by at least two out of three licensed physicians
(one selected by the Employer, one selected by the Executive and one selected by
the other two physicians).  In the event that the Executive's incapacity
continues for a period exceeding twenty-four (24) consecutive months, the
Employer may terminate this Agreement upon notice, without need for any
certification of incapacity by licensed physicians.  In the event that this
Agreement is terminated pursuant to the provisions of this Section 5, the
Employer shall have no further obligations hereunder other than (i) the
Employer's obligation to pay to the Executive all amounts of Salary and Annual
Incentive Award, and compensation pursuant to Section 3(d) as set forth in this
Section 5 accrued to date of termination, (ii) its obligation to continue
coverage of the Executive under the Employer's life, health and medical plans in
which he was then a participant, (iii) such further obligations to the Executive
as the Employer deems appropriate, and (iv) the payment of any Long-Term
Incentive Award pursuant to Section 5(b) below.  For purposes of this Section 5,
the Employer's obligation to pay the Salary shall be offset by any payments made
to the Executive during any such period of incapacity pursuant to any short-term
sickness and accident policy or long-term disability policy, the premiums for
which are paid by the Employer, and by the amount of any workers' compensation
if those benefits are not taken into account by the disability policy.

          (b)  In the event that this Agreement is terminated by the Employer
because of the Executive's incapacity, the Executive shall be eligible to
receive a prorated share of his Long-Term

                                       10
<PAGE>
 
Incentive Award.  Any such award shall be paid to him by the Employer after the
close of the calendar year ending December 31, 2001.  The prorated award shall
be the amount of the award otherwise payable to the Executive except for the
incapacity divided by a fraction, the numerator of which is the number of whole
months during the term of this Agreement until the date which is six (6) months
from the date the Executive last worked because of incapacity and the
denominator is 72.  No interest will accrue on the Long-Term Incentive Award
from the date of the Executive's termination due to incapacity until it is paid
him.

     6.   (a)  During the Employment Term, and, except in the case of a
termination of the Employment Term because of a Section 2(b) Termination, for a
period of two (2) years from the date of termination of the Employment Term:

               (i) The Executive shall not, in the United States of America, the
     Commonwealth of Puerto Rico and any other country or territory in which the
     Employer or any of its affiliates or, if the Partnership Reorganization
     Transactions are consummated, Holding Company or any of its affiliates
     (including, without limitation, Calgene), conduct, either at, or at any
     time during the two-year period preceding the date of termination of the
     Employment Term, significant (which shall, without limitation of the
     generality of the foregoing, be deemed to include any country or territory
     in which the Partnership or its affiliates or Holding Company, or any of
     its affiliates (including, without limitation, Calgene) has or had $1.0
     million or more in annual sales)) business (including, for these purposes,
     but without limitation, the sale or marketing of any product)
     (collectively, the "Covered Jurisdictions"), be engaged, directly or
     indirectly, either for his own account or as agent, consultant,
     representative, employee, partner, officer, director, stockholder or
     otherwise of any person, firm, corporation or enterprise engaged in

                                       11
<PAGE>
 
     either (A) any aspect of the business of growing, packing or marketing
     tomatoes or other products grown, packed or marketed by the Employer; (B)
     any other business conducted by the Employer or its affiliates either at,
     or at any time during the two-year period preceding the date of termination
     of the Employment Term ("Other Business Activities of the Employer"); or
     (C) if the Partnership Reorganization Transactions are consummated, any
     aspect of the cotton, oils or other businesses conducted by Holding
     Company, or any of its affiliates (including, without limitation, Calgene),
     at any time during the two-year period preceding the date of termination of
     the Employment Term (collectively, the "Covered Businesses");

              (ii)  the Executive shall not render financial or other assistance
     to any person, firm, corporation or enterprise engaged in the Covered
     Businesses in the Covered Jurisdictions;

             (iii)  the Executive shall not, directly or indirectly, buy from
     or sell to, solicit the business of or broker to or sell for, or perform
     any services within the Covered Businesses for, any person or entity who
     was a customer of the Employer or any of its affiliates or, if the
     Partnership Reorganization Transactions are consummated, Holding Company or
     any of its affiliates (including, without limitation, Calgene), or who
     became such a customer within two years after termination of the
     Executive's employment;

              (iv)  the Executive shall not solicit for employment, hire, or
     induce to leave the service of the Employer or any of its affiliates, any
     employee, salesman, agent or representative of the Employer or any of its
     affiliates who was engaged in any activities within the Covered Businesses
     and who was such either at or at any time during the one-year

                                       12
<PAGE>
 
     period preceding the date of termination of the Employment Term; and

               (v)  the Executive shall not use or permit the Executive's name
     to be used in connection with any business or enterprise engaged in any
     activities within the Covered Businesses.

In Clause B of Section 6(a)(i) and in Sections 6(a)(iii) and 6(a)(iv), the term
"affiliate" shall be limited to subsidiaries of the Employer or, in the case of
other affiliates, to business activities of the affiliate of the type described
in Clause A of this Section 6(a)(i), Other Business Activities of the Employer
and to other business activities of the affiliate to which the Executive has
devoted direct supervision or substantial activity.  If the Partnership
Reorganization Transactions are consummated, the term "affiliate" in Clause C of
Section 6(a)(i) and in Sections 6(a)(iii) and 6(a)(iv) shall be limited to
Holding Company and its other subsidiaries (including, without limitation,
Calgene).

Notwithstanding the foregoing, the Executive may participate in any manner in
the business activities of Chile Financial Investments Associates, Inc. and
Gargiulo Landco, Inc. (provided that, for the period during which the Executive
is subject to the restrictions of this Section 6(a), the Executive shall not
propose or consent to such entities entering into any new business not conducted
by such entities on December 23, 1992, the effective date of the Original
Employment Agreement, that competes with any of the Covered Businesses in any of
the Covered Jurisdictions), and the operation of a vineyard in Napa Valley,
California, and such activities of the Executive (and the Executive's ownership
interests in lands which are leased to the Employer or its affiliates) shall not
be deemed a breach of the foregoing provisions of this Section 6(a) or to
constitute a conflict of interest with the Executive's duties to the Employer
under Section 1 of this Agreement.

                                       13
<PAGE>
 
          (b)  The Executive agrees that a violation on the part of the
Executive of the covenants contained in Section 6(a) will cause irreparable
damage to the Employer, and that it is and will be impossible to estimate or
determine the damage that will be suffered by the Employer in the event of a
breach by the Executive of such covenants. Therefore, the Executive further
agrees that the Employer shall be entitled to an injunction from any court of
competent jurisdiction restraining any further violation of such covenants by
the Executive, his employer, employees, partners, agents or other associates, or
any of them, such right to an injunction to be in addition to whatever other
remedies the Employer may have. In addition, the Employer may, as provided in
Section 7 of this Agreement, terminate this Agreement for breach of the
provisions set forth in Section 6(a).

          (c)  The invalidity of any one or more of the words, phrases,
sentences or clauses contained in this Section 6 shall not affect the
enforceability of the remaining portions of this Section. If one or more of the
words, phrases, sentences or clauses contained in this Section shall be invalid,
this Section shall be construed as if such invalid word or words, phrase or
phrases, sentence or sentences or clause or clauses had not been inserted, and
if such invalidity should be caused by the length of any period of time, the
size of any area, or the service or product limitations set forth in this
Section, such period of time or such area or such service or product
limitations, or all of them, shall, without need of further action by any party
hereto, be deemed to be reduced to a period, area, service or product that will
cure such invalidity.

          (d)  In the case where this Agreement terminates because of a Section
2(b) Termination, all of the terms, conditions and provisions of Section 6(a)-
(c) above shall also apply, except that restrictions shall extend only for a
period of one year from the effective date of the termination of this Agreement.

                                       14
<PAGE>
 
     7.   (a)   In the event of the death of the Executive, this Agreement shall
terminate, without notice, on the date of the happening of such event, and the
Employer shall have no further obligations hereunder other than (i) for payment
of Salary and compensation pursuant to Section 3(d) to which the Executive is
entitled, accrued through the date of death, (ii) for continued regular payments
of Salary for a period of six (6) months after the date of death, to the
Executive's wife if she then be living and, if not, to the Executive's estate,
(iii) payment of an Annual Incentive Award (prorated during the calendar year in
which the Executive dies) no later than two and one-half months following the
close of the calendar year during which the Executive died, and (iv) those with
respect to any employee benefit plan in which the Executive shall have
participated that arise because of or survive his death.  The Executive's
designated beneficiary also shall be eligible to receive a prorated share of his
Long-Term Incentive Award to be paid after the close of the calendar year ending
December 31, 2001.  The prorated award shall be the amount of the award
otherwise payable to the Executive had he lived, divided by a fraction, the
numerator of which is the number of whole months during the term of this
Agreement until the Executive's death and the denominator is 72.  No interest
will accrue or be paid on the Long-Term Incentive Award from the date of the
Executive's death until it is paid to his designated beneficiary.

          (b)  For purposes of this Agreement, "Cause" shall mean (i) a willful
violation on the part of the Executive of the covenants contained in Section 1,
Section 6(a), or Section 9, (ii) the willful misconduct or gross negligence on
the part of the Executive which is materially and demonstrably injurious to the
Employer or is otherwise a material breach of fiduciary duties owed to the
Employer, or (iii) an act or acts by the Executive constituting a violation of
applicable laws which is materially and demonstrably injurious to the Employer
and which the Executive knew or reasonably should have known constituted a
violation of law. The

                                       15
<PAGE>
 
Employer may terminate the Executive's employment under subsection (i) or (ii)
of this Section 7(b) only if the Executive is given prior written notice
specifying the nature of the alleged Cause and the Executive has been given a
reasonable opportunity (which shall be not less than sixty days) to take
remedial action but failed or refused to do so.

          (c)  In the event that the Executive voluntarily  terminates his
employment with the Employer, the Employer shall pay to the Executive as final
remuneration all amounts of Salary and  compensation pursuant to Section 3(d)
accrued, due and payable  under this Agreement to the effective date of
termination, to the extent not previously paid to the Executive, and the
Employer shall  have no further obligation to the Executive.  The Executive
shall not be eligible for any Annual Incentive Award for the calendar year in
which the Executive voluntarily terminated employment, and the Executive shall
not be entitled to any Long-Term Incentive Award.  Moreover, the Executive's
"Voluntary Termination" (as hereinafter defined) of employment shall be deemed
to be a breach of this  Agreement.  For purposes of the preceding sentence,
"Voluntary Termination" shall mean the Executive voluntarily and without being
induced or caused to do so by the Employer, resigning his position with the
Employer in writing.  Without limiting the foregoing, Voluntary Termination
shall not include, and the Executive shall not be subject to a claim for breach
of contract under this Section, due to (i) the Employer terminating the
Executive without Cause, including, without limitation, due to the Executive's
failure to meet any performance goals or targets, (ii) Termination by the
Executive for Good Reason, (iii) a failure of the parties to agree upon a
renegotiated employment agreement pursuant to Section 2(b) hereof upon a failure
to reach 70% of the Cumulative Plan by December 31, 1998 and the Executive
resigning as a result thereof, (iv) the death or disability of the Executive,
(v) any nonrenewal of the Employment Term, or (vi) any Termination of the
Executive For Cause.  The provision described above limiting

                                       16
<PAGE>
 
the Employer's right to a claim for breach of contract under circumstances not
constituting a Voluntary Termination is not meant to limit the Employer's right
to other types of claims under any other provision of this Agreement under such
circumstances.

          (d)  The Executive may, at his option, exercisable by notice to the
Employer given within ninety (90) days after the Executive first becomes aware
of the occurrence of such event, terminate this Agreement, effective as of a
date specified in such notice, upon the occurrence of any one or more of the
following (each a "Termination by Executive for Good Reason"):

               (i)  the reassignment of the Executive by the Employer, without
     the Executive's express written consent, to a position with the Employer
     other than that of Chief Executive Officer, or to a position with the
     Company other than that of Chief Executive Officer, or a material adverse
     change in the nature or scope of the Executive's authorities, powers,
     functions, duties or responsibilities in those positions; provided,
     however, that the consummation of the Partnership Reorganization
     Transactions shall not be deemed a violation of this provision;

              (ii)  The Employer's failure to perform its obligations under this
     Agreement in any material respect, including without limitation the failure
     by the Employer to pay compensation in accordance with this Agreement or
     the failure of the Employer to provide the Executive with fringe benefits
     substantially the same as those previously provided under this Agreement;

             (iii)  The Employer's requiring the Executive, without the
     Executive's express written consent, to change his place of permanent
     residency or to spend more than one-half of the time in which he performs
     his duties for the Employer in a

                                       17
<PAGE>
 
     place outside of Collier County, Florida, provided that any time that he
     spends outside of Collier County engaging in any activity for Monsanto,
     Holding Company or Calgene (if the Partnership Reorganization Transactions
     are consummated) shall not be counted;

              (iv)  unless the Executive gives prior written consent:  (A) the
     Employer's failure to continue the use of the name "Gargiulo" in its
     business name; (B) the sale, exchange or other disposition of a material
     portion of the Employer's assets (other than assets which may be
     contributed to the Employer by Calgene, Holding Company or Monsanto if the
     Partnership Reorganization Transactions are consummated) to a third party
     unrelated to the Employer, Holding Company, Calgene or Monsanto, such that
     the value of the remaining assets of the Employer and its subsidiaries
     which are consolidated with the Employer are materially diminished; (C) the
     transfer of a material portion of the Employer's assets (other than assets
     which may be contributed to the Employer by Calgene, Holding Company or
     Monsanto if the Partnership Reorganization Transactions are consummated) to
     Holding Company, Calgene or Monsanto or any of their affiliates if (1) the
     transfer materially diminishes the Employer's abilities to conduct its
     business as previously conducted prior to the transfer and thereby causes
     it not to be reasonably possible for it to achieve the Earnings Targets, or
     (2) after the transfer, it is not reasonably possible to measure the
     financial return on the transferred assets and thereby causes it not to be
     reasonably possible to measure the return to the Employer, including the
     transferred assets; (D) if the Partnership Reorganization Transactions are
     consummated, a material breach by Monsanto or Holding Company or any of
     their successors of the Gargiulo Credit Facility Agreement between Monsanto
     and Holding Company; (E) if the Partnership Reorganization Transactions are
     not consummated,

                                       18

     the failure by Monsanto to enter into a Gargiulo Credit Facility Agreement
     that is comparable to the Gargiulo Credit Facility Agreement between
     Monsanto and Holding Company, and once the Monsanto Gargiulo Credit
     Facility Agreement is executed, a material breach of that Agreement by
     Monsanto; (F) the removal from the Employer by dividend or distribution to
     the owners of the Employer, capital or assets such that the achievement of
     the Earnings Targets described in Schedule 2 hereof are not reasonably
     possible; or (G) the taking of any other actions by Monsanto or, if the
     Partnership Reorganization Transactions are consummated, by Holding Company
     or Calgene, which materially diminishes the Employer's abilities to conduct
     its business and thereby causes it not to be reasonably possible to achieve
     the Earnings Targets;

provided, in each case, that the event was suffered or incurred involuntarily
by, or without the express written consent of, the Executive and is not cured by
the Employer within thirty (30) days after the Employer receives written notice
from the Executive specifying the event that the Executive asserts constitutes a
basis for Termination by Executive for Good Reason.  Notwithstanding anything in
this Section 7(d)(iv) to the contrary, the Partnership Reorganization
Transactions and any Restructuring Event, as defined in Section 8 below, shall
not be the basis for a Termination by Executive for Good Reason.

               (e)  (i)  Upon any termination of this Agreement because of a
     Section 2(b) Termination, the Employer shall pay to the Executive, in
     addition to all sums then accrued, due and payable under this Agreement, an
     additional amount equal to the Executive's Salary paid or payable to the
     Executive for the calendar year ending December 31, 1998.  The amount shall
     be payable in a single sum within thirty days after the effective date of
     the termination of this Agreement because of the Section 2(b) Termination.
     In addition, the Employer shall

                                       19
<PAGE>
 
     maintain or provide, at no cost to the Executive, group medical and other
     insurance coverages on the Executive and his family, to the extent
     previously received by the Executive under this Agreement for one year
     following the effective date of the termination of this Agreement because
     of the Section 2(b) Termination.

              (ii)  Upon any termination of this Agreement by the Employer
     without Cause, or any timely nonrenewal by the Employer of the Employment
     Term pursuant to Section 2(a) of this Agreement, or any Termination by
     Executive for Good Reason, the Employer shall pay to the Executive, in
     addition to all sums then accrued, due and payable under this Agreement, an
     additional amount equal to twice the Executive's Salary paid or payable to
     the Executive for the calendar year in which the effective date of the
     termination of this Agreement occurs, which amount shall be payable in a
     lump sum within thirty (30) days after the effective date of termination of
     this Agreement. The Employer also shall maintain or provide, at no cost to
     the Executive, group medical and other insurance coverages on the Executive
     and his family, to the extent previously received by the Executive under
     this Agreement, for at least two years after any such termination of this
     Agreement.  In addition, upon the termination of this Agreement by the
     Employer without Cause, any timely nonrenewal by the Employer of the
     Employment Term pursuant to Section 2(a) of the Agreement or any
     Termination by Executive for Good Reason, the Employer shall pay to the
     Executive, if the termination occurs on or before December 31, 1998, an
     amount equal to one times the Annual Incentive Award, or if the termination
     occurs on or after January 1, 1999, an amount equal to two times the Annual
     Incentive Award, in each case paid the Executive for the calendar year in
     which the termination took place or for the prior calendar year, whichever
     Annual Incentive Award is greater.  The payment of

                                       20
<PAGE>
 
     this amount shall be paid to the Executive no later than two and one-half
     months after the end of the calendar year in which the termination took
     place.

             (iii)  In the event of a Section 2(b) Termination, the termination
     of this Agreement by the Employer without Cause or by reason of nonrenewal
     of the Employment Term, or Termination by Executive for Good Reason, the
     Executive shall have no duty to seek other employment or otherwise mitigate
     the amount of compensation payable to him under the terms of this
     Agreement, and the amounts payable to the Executive hereunder shall not be
     reduced because of any new Employment the Executive may obtain after
     termination.

              (iv)  In addition, upon termination of this Agreement by the
     Employer without Cause or any Termination by Executive for Good Reason
     (hereinafter sometimes collectively referred to as "Termination"), the
     Executive shall be eligible to receive a prorated share of the Annual
     Incentive Award for the year in which the Termination occurs and shall also
     be eligible to receive a prorated share of his Long-Term Incentive Award to
     be paid to him within two and one-half months after the close of the
     calendar year ending December 31, 2001.  The prorated Long-Term Incentive
     Award shall be the amount of the Award otherwise payable to the Executive
     (except for the Termination) divided by a fraction, the numerator of which
     is the number of whole or partial months during the term of this Agreement
     until the effective date of the Executive's termination and the denominator
     is 72.  No interest shall accrue or be paid on the Long-Term Incentive
     Award from the date of the Executive's Termination until it is paid to him.

          (f)  Upon the Termination of this Agreement by the Employer for Cause,
the Employer shall pay to the Executive all

                                       21
<PAGE>
 
Salary then accrued, due and payable under this Agreement.  The Employer shall
be under no obligation to pay the Executive any Annual Incentive Award for the
calendar year in which the termination of this Agreement by the Employer for
Cause occurred, nor shall the Executive be eligible for any Long-Term Incentive
Award.

          (g)  In all cases where the Executive or his estate or heirs has a
right to receive a pro rata share of his Long-Term Incentive Award following his
termination, death or disability, the Employer shall provide to the Executive or
his personal representative two and one-half months after the close of its
fiscal year copies of its audited financial statements as well as a calculation
of the EBIT for the Employer for the calendar year then ended; provided,
however, if the Partnership Reorganization Transactions are consummated, the
financial statements provided by the Employer are not required to be audited.

          (h)  Notwithstanding any other provision of this Agreement, the
Employer's obligations to continue any benefits under any employee benefit plan
after the termination of this Agreement shall be subject to the timely making,
by the Executive or his beneficiary, of any elections required by the terms of
such plan and the payment, if required, of any premiums therefor.

          (i)  The Executive agrees that any payments required under this
Section 7 that constitute continuation of the Executive's Salary beyond
termination of the Employment Term shall be reduced by any and all severance
payments which the Executive receives under any severance plan or program of the
Employer. Except as specifically otherwise provided in this Agreement, the
Executive acknowledges and agrees that he will not be entitled to accrue or be
eligible for any vacation pay, Annual or Long-Term Incentive Awards or other
benefits during periods following his termination with respect to which he is
paid or entitled to be paid

                                       22
<PAGE>
 
any amounts, or provided any benefits pursuant to this Section 7.  However, the
preceding sentence shall not be deemed to release the Employer from its
obligation to pay the Executive any other compensation or benefits to which the
Executive is specifically entitled during periods following his termination
pursuant to this Agreement. The Executive and the Employer agree that, in the
event that any health, disability or life insurance benefits required to be
provided under this Section 7 cannot be provided under the terms of the plans
maintained by the Employer for any reason, the Employer shall satisfy the
requirement to provide such health, disability or life insurance benefits by
purchasing other comparable benefits and making them available to the Executive
at the same after-tax cost, provided, in the case of disability insurance, that
the same is obtainable, using reasonable efforts, on commercially reasonable
terms.

     8.   In the event that there occurs a Restructuring Event prior to June 30,
2001, to-wit:

          (a)  the sale of more than fifty percent of the stock or other equity
interest of the Employer to a person, corporation or entity other than to
Holding Company, a Holding Company affiliate, Calgene, a Calgene affiliate (in
the Partnership Reorganization Transactions or otherwise), Monsanto or a
Monsanto affiliate;

          (b)  the sale of all or substantially all of the assets of the
Employer to a person, corporation or entity other than to Holding Company, a
Holding Company affiliate, Calgene, a Calgene affiliate (in the Partnership
Reorganization Transactions or otherwise), Monsanto or a Monsanto affiliate; or

          (c)  there occurs a registered public offering of more than twenty-
five percent of the stock of the Employer;

                                       23
<PAGE>
 
and the net amount realized by the Employer or the shareholders of the Employer
exceeds the net cumulative capital invested (i.e., cumulative capital invested
reduced by cumulative capital returned in the form of dividends or other
distributions) by Monsanto and its affiliates and Holding Company and its
affiliates in the Employer plus a 14% cost of capital factor (compounded
annually), then the Executive shall be entitled to receive an amount equal to
five percent (5%) of the excess ("Restructuring Event Award"), but in no event
shall the amount payable to the Executive as a Restructuring Event Award exceed
the maximum Long-Term Incentive Award payable to the Executive under this
Agreement, and provided further, that the amount of the Restructuring Event
Award shall be reduced by the amount of any Long-Term Incentive Award paid to
the Executive hereunder.  The Restructuring Event Award shall be fully earned
upon the occurrence of the Restructuring Event and shall not be forfeited or
reduced in the event that no amount of Long-Term Incentive Award is payable to
the Executive hereunder.  The Restructuring Event Award shall be payable no
later than two and one-half months after the close of the calendar year ending
December 31, 2001.  No interest shall accrue or be paid on the Restructuring
Event Award from the date of the Restructuring Event until it is paid.  In the
event that there is a dispute over the net amount realized or the amount of the
investment and cost of capital factor, or any other financial issue, the dispute
shall be referred to Monsanto's independent certified public accountants or, if
the Partnership Reorganization Transactions are consummated, to the Certified
Public Accountants for them to resolve, using generally accepted accounting
principles.  The determination of Monsanto's certified public accountants or the
Certified Public Accountants, as the case may be, shall be final and binding on
all parties absent manifest error.

     9.   (a)  The Executive acknowledges that, during and as a result of his
employment hereunder, he may have access to trade secrets and other confidential
information of the Employer and

                                       24
<PAGE>
 
Holding Company and their respective affiliates, including but not limited to
the nature and material terms of business opportunities and proposals available
to the Employer, Holding Company and Calgene and their respective affiliates,
the Employer's, Holding Company's or Calgene's and their respective affiliates'
methods and systems, the names and addresses of the Employer's, Holding
Company's or Calgene's and their respective affiliates' customers and suppliers,
technical memoranda, research reports, designs and specifications, operating
procedures, ledgers and other information, data and documents relating to the
Employer's, Holding Company's and Calgene's and their respective affiliates'
present or future operations, whether or not any such information, data or
documents qualify as a "trade secret" under applicable federal or state law
(collectively, the "Confidential Information").  The Executive covenants and
agrees that he shall not at any time during or following any termination of this
Agreement, without the consent of the Employer, Holding Company or Calgene or
their affiliates, respectively, use or disclose (except for the sole and
exclusive benefit of the Employer, Holding Company or Calgene or their
affiliates, respectively, or as required to perform his duties under this
Agreement or as required by law or as is already in the public domain) any
Confidential Information which has been obtained by or disclosed to him as a
result of his employment with the Employer.  The Executive agrees that the
Employer and Calgene would be irreparably harmed by any breach of the
Executive's agreements set forth in this Section 9, that such injury would not
be adequately compensated by monetary damages, and that, accordingly, Monsanto,
the Employer, Holding Company or Calgene, whichever corporation is appropriate,
may specifically enforce the provisions of this Section by injunction without
thereby affecting any claim for damages.

          (b)  Upon termination of this Agreement, the Executive shall promptly
return to the Employer, Holding Company and Calgene, respectively, all documents
(including without limitation copies

                                       25
<PAGE>
 
and notes relating to such documents) and other materials and property of the
Employer, Holding Company or Calgene, or pertaining to their businesses,
including without limitation customer and prospect lists, contracts, files,
manuals, letters, reports and records in his possession or control, including
all computerized records, files and computer programs, tapes or discs, no matter
from whom or in what manner acquired.

          (c)  The Executive agrees that he will fully disclose, and shall
assign and transfer to the Employer, its successors and assigns, the entire
right, title and interest in the development of a new variety of plant,
patentable or unpatentable, conceived by the Executive during the Employment
Term and relating, in the opinion of the Employer, in any way to the Employer's
business (an "Invention"). Such assignment shall include the right to obtain
letters of patent or plant patents, in the name of the Employer or otherwise, on
such Inventions in the United States or in any foreign countries, covering such
Inventions. The Executive agrees to sign all papers and to make all oaths
necessary for the filing and prosecution of any applications for such letter of
patent or plant patents, or any divisions, continuations, continuations in part,
renewals or reissue thereof, and to execute on request all papers necessary to
assign such Inventions to the Employer. The Executive will promptly disclose to
the Employer every Invention and every scientific product, process, apparatus or
design that the Executive, individually or jointly, during the Employment Term,
may invent, discover, conceive or originate, relating in any way to the
Employer's ability to develop new hybrids and plant varieties.
 
     10.  Any notice required or permitted to be given under this Agreement
shall be in writing, and shall be given by hand-delivery to the addressee, by
deposit in the U.S. mail, postage prepaid, certified mail, return receipt
requested, by overnight courier service, or facsimile transmission followed by
written confirmation sent in one of the manners specified above, as follows:

other. Any notice sent in accordance with the foregoing provisions shall be
deemed given on the date of receipt if personally delivered, or on the date

     11.  This Agreement and the Cooperation Agreement incorporate the entire
agreement between the parties hereto pertaining to the subject matter hereof,
and supersede all prior and contemporaneous agreements, understandings,
negotiations and discussions of the parties, whether oral or written (including,
without limitation, any agreements or contracts regarding employment of the
Executive with NTG or any other predecessor to any business of the Employer,
which agreements and contracts are in all respects cancelled and any rights or
remedies thereunder are hereby waived by the Executive and the Employer), and
there are no warranties, representations or other agreements between the parties
in connection with the subject matter hereof, except as specifically set forth
herein. No amendment, supplement, modification or waiver of this Agreement shall
be binding upon a party hereto unless in writing and executed by such party.

     12.  It is the intention of the parties hereto that all questions with
respect to the construction of this Agreement and the rights and liabilities of
the parties hereto shall be determined in accordance with the laws of the State
of Delaware applicable to business agreements entered into and performed
entirely within the State of Delaware.

     13.  Each of the provisions of this Agreement shall be independent of all
other provisions, and if any provision of this Agreement is declared void or
invalid by any court or other governmental agency of competent jurisdiction,
each other provision of this Agreement shall remain in full force and effect and
shall be construed to the extent possible as consistent with all other valid
provisions in order to carry out the intent of the parties hereto.
Notwithstanding the termination or expiration of this Agreement for any reason,
the Executive's obligations under

                                       28
<PAGE>
 
Sections 6 and 9 hereof shall survive and remain in full force and effect for
the periods therein provided, and the provisions for equitable relief in
Sections 6 and 9 hereof shall continue in force.

     14.  This Agreement shall be binding upon and inure to the benefit of the
respective heirs, executors, administrators, successors and assigns of the
Employer and the Executive. If the Employer shall, at any time, be merged with
or consolidated into or with any other corporation or person or if all or
substantially all of the assets of the Employer are transferred to another
corporation or person in connection with the Partnership Reorganization
Transactions or otherwise, the provisions of this Agreement shall be binding
upon and inure to the benefit of the entity resulting from such merger or
consolidation or the corporation or person to which or to whom such assets shall
be transferred, and this provision shall apply in the event of any subsequent
mergers, consolidations or transfers of assets. Except as provided in this
Section 14, and except for the Partnership Reorganization Transactions, neither
the Employer nor the Executive may assign its or his interest in this Agreement
or any part hereof. The Executive acknowledges and agrees that he has had the
opportunity and been given sufficient time to read this Agreement, that he
understands this Agreement's terms and conditions, that he has had any questions
regarding the meaning of this Agreement answered to his satisfaction, and that
he has retained competent counsel to represent him with respect to this
Agreement. Nothing in this Agreement shall require the Employer to segregate
monies from its general funds or create any trusts or special deposits to secure
payment of any obligations hereunder.  This Agreement shall not be construed
more strictly against one party than against the other merely by virtue of the
fact that this Agreement may have been physically prepared by one of the
parties, or such party's counsel, it being agreed that both parties and their
respective counsel have mutually participated in the negotiation and preparation
of this Agreement.

                                       29
<PAGE>
 
     15.  If the Partnership Reorganization Transactions are consummated, the
Executive agrees to execute with Holding Company and its affiliates (including,
without limitation, Calgene), agreements relating to noncompetition,
Confidential Information and Inventions substantially similar to those set forth
in this Agreement as may reasonably be advisable or necessary in furtherance of
the transaction and as may be needed by Holding Company or Calgene and its
affiliates to protect their interests with respect to the transaction.  In the
event that the Partnership Reorganization Transactions are not consummated, all
references in this Agreement to Holding Company or Calgene shall be null and
void, except to the extent necessary to protect any information about its
businesses and operations that the Executive may have learned as part of his
involvement, if any, in connection with the proposed Partnership Reorganization
Transactions.  Each of Holding Company and Calgene may enforce the terms of this
Agreement with respect to the provisions applicable to it even though it is not
a party to this Agreement.

     16.  The Executive acknowledges the fact that another employee of the
Employer will receive a similar Employment Agreement providing the employee with
eligibility for Annual and Long-Term Incentive Awards similar to those for which
the Executive is eligible under this Agreement.  Executive acknowledges and
agrees that, in the event that the other employee terminates his employment with
the Employer in such a way that he is not eligible for all or any Annual or
Long-Term Incentive Awards, or if either the Annual or Long-Term Incentive
Awards shall, for whatever reason, not be paid to the other employee, the amount
of the Annual or Long-Term Incentive Awards otherwise payable to the Executive
hereunder shall not be increased or decreased.

     17.  The Executive hereby acknowledges that right to the use of the name
"Gargiulo" is an asset of the Company and the

                                       30
<PAGE>
 
Partnership and may be used by the Employer and its successors and assigns both
during and after the Employment Term.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement on and as of
the date first above written.

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

              This Amendment, effective 1 June 1993, is between NT

         DRESICK FARMS, INC., a California corporation ("Dresick").

                                   RECITALS

              A.    Gargiulo and Dresick formed a California general
         partnership named "NT Gargiulo & Dresick Associates" pursuant to
         Articles of Partnership dated 14 January 1993 ("Articles of
         Partnership").

              B.    The parties desire to amend the Articles of Partnership
         as here set forth.


              C.    For good and valuable consideration, the receipt and
         sufficiency of which is acknowledged, the parties agree as
         follows:

                    1.  The Articles of Partnership are amended by deleting
              Section 3.03 (entitled "Management") in its entirety, and by
              substituting the following:

                        Management.
                        ----------

                        3.03 Gargiulo shall manage the Partnership business
                    on a day-to-day basis.  Notwithstanding the foregoing,
                    action on the following matters shall require the
                    approval of Dresick:

                               (i)  Sale of all or substantially all of the
                    assets of the Partnership, whether by direct sale,
                    merger, consolidation or otherwise.

                              (ii)  Pledging or otherwise encumbering all
                    or substantially all of the Partnership assets.

                             (iii)  Making capital improvements having a
                    cost in excess of One Hundred Thousand and no/100
                    Dollars ($100,000.00) for each such capital
                    improvement.

                        In the event of disagreement between the Partners
                    with respect to any matter which requires the approval
                    of both Partners, the Partners shall first attempt to
                    resolve such dispute by negotiation and compromise.

                    2.  Except as here amended, the Articles of Partnership
              remain in full force and effect.

              WHEREAS, the Venturers operate certain businesses connected with

         tomatoes; and

              WHEREAS, the Venturers have a joint interest in the development of
         improved plant varieties and believe that it would be prudent to join
         together in a joint venture to fund a research facility to discover and

         individual business operations and to employ at said facility a person
         or persons having the educational background and experience necessary
         to conduct such research; and

              WHEREAS, the risk of the Venture and the anticipated cost of a
         magnitude that no one Venturer would be willing to undertake the
         project alone, but collectively, the Venturers believe the potential
         would justify the risks involved, and the Venturers desire, therefore,
         to conduct the project in joint venture form for the purposes
         hereinabove and hereinafter provided.

              NOW, THEREFORE, in consideration of the premises which shall be
         deemed to be an integral part of this agreement and not as mere
         recitals hereto, and of the mutual agreements herein contained, it is

         of the Venture and any Venturer fails to make its full share of such
         additional contributions within thirty (30) days after the required or
         agreed date thereof, then the other Venturers may make such
         contribution (hereinafter called the "Contributing Venturers") in which
         event the proportionate Venture interest of the Venturer failing to
         make such additional contribution (hereinafter called the "Delinquent
         Venturer") shall be decreased by twice the percentage equal to the
         percentage which such additional contribution to the Venture bears to

         adjustment shall be reinstated. Said cure shall only be accomplished by
         payment by the Delinquent Venturer to the Contributing Venturer or
         Venturers of an amount equal to fifteen percent (15%) of the Delinquent
         Venturer's required share. In the event that Delinquent Venturer's
         contribution is not made by any other Venturer but other Venturers have
         contributed their shares of the additional contribution, then in that
         event, upon expiration of one hundred twenty (120) days

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

              A.   Restrictions on Granting Security Interest. A Venturer shall
                   ------------------------------------------
         not, directly or indirectly, mortgage, encumber, pledge or assign or
         transfer for financing purposes or otherwise give or grant any security
         interest in all or any part of its Venture interest without first
         obtaining the consent of the other Venturers. In the event such consent
         is obtained, the mortgagee, encumbrancer, pledgee, assignee, or
         transferee shall be entitled to receive Venturer's interest in the
         profits and losses of the Venture and should liquidation of the Venture
         occur, the right to receive the Venturer's allocable share of the

         to the mortgagee, encumbrancer, pledgee, assignee, or transferee to
         participate or interfere in the management of the administration of the
         Venture's business or affairs. The consent to directly or indirectly,
         mortgage, encumber, pledge or assign or transfer for financing purposes
         or otherwise give or grant any security interest shall not otherwise
         release such Venture interest from the other restrictions contained in
         this Agreement, but such restrictions shall merely become subject to
         the security interest to which such consent expressly applies for the
         duration of such security interest only, and in the event the holder of
         such security interest shall foreclose upon such Venture interest or
         otherwise acquire such Venture interest, such holder shall take such
         Venture interest subject to the restrictions contained in this
         Agreement, and it shall be subject to all such restrictions the same as
         if such holder were a party to this Agreement.

              B.   Restrictions on Transfer. A Venturer shall not, directly or
                   ------------------------

         affiliates, subsidiaries, an entity substantially owned by the
         Venturer's shareholders or the Venturer's shareholders without first
         obtaining the consent of the other Venturers, or in the absence of such
         consent, without first complying with all of the following terms and
         conditions:

<PAGE>
 
         indirectly, to sell, assign, transfer or otherwise deal with or dispose
         of all or any part of its Venture interest, the Venturer (hereinafter
         referred to as the "selling Venturer") shall be required to offer to
         sell its Venture interest by delivering a notification (hereinafter
         referred to as the "offer to sell"), signed by the selling Venturer to
         the other Venturers, stating the amount of its Venture interest which
         it desires to sell, assign or transfer. The other Venturers shall then
         have the option to purchase their proportionate share of the Venture
         interest offered pursuant to the offer to sell or the share of
         Venturers not exercising their option, which option may be exercised by
         delivering a notification of acceptance to the selling Venturer within
         sixty (60) days after delivery to it of the said offer to sell.

              C.   Determination of Purchase Price and Terms. In the event that
                   -----------------------------------------
         any Venture interest is to be purchased pursuant to the foregoing
         provisions of this Article XII, the following provisions shall apply:

         Article XII shall be paid in accordance with the provisions of
         Paragraph F of this Article.

              D.   Right of Selling Venturer to Sell. In the event that the
                   ---------------------------------
         other Venturers fail or refuse to purchase all of the Venture interest
         offered for sale by the selling Venturer pursuant to the offer to sell
         in accordance with the provisions of this Agreement, then after the
         expiration of the option period, the selling Venturer shall be free to
         sell, transfer or otherwise dispose of the Venture interest offered
         pursuant to the offer to sell made and delivered in accordance with the
         provisions of this Agreement and not accepted for purchase by the other
         Venturers, as hereinabove provided, to any person or entity, in any
         manner and upon any terms and conditions; provided however, that such
         selling Venturer shall not in fact sell, transfer or otherwise dispose
         of any Venture interest to any person or entity either for a price less
         than or on terms more favorable than the purchase price and the terms
         fixed by this Agreement without first offering the other Venturers the
         right to purchase such Venture interest at the same price and upon the
         same terms as agreed between such selling Venturer and any other person
         or entity. In carrying out the intent of the immediately preceding
         sentence, the same procedure and time periods as specified in the
         preceding paragraphs of this Article shall again be followed except
         that the notice provided

         entity to whom the selling Venturer proposes to sell its Venture
         interest and the price and terms offered by such person or entity for
         such Venture interest. The selling Venturer shall also provide the
         other Venturers with a copy of the contract of sale (subject to the
         right of first refusal herein granted to the other Venturers) and
         evidence of a deposit made by the proposed purchasers which must be
         equal to not less than Five Percent (5%) of the purchase price. In the
         event that the other Venturers shall then fail or refuse to purchase
         all the Venture interest offered for sale pursuant to this Agreement,
         then after the expiration of the option period, the selling Venturer
         shall not be required to sell any part of its Venture interest to the
         other Venturer, but shall then be free to sell to such other person or
         entity the Venture interest not purchased by the other Venturers in
         accordance with the foregoing provisions of this Agreement for the
         price and upon the terms set forth in such notice. Any sale, or other
         disposition that may take place after the end of all applicable option
         periods specified above must, in any event, take place within ninety
         (90) days following the close of all applicable option periods, and
         upon the expiration of such ninety (90) day period, the provisions of
         this Agreement shall reattach to all of the Venture interest not sold,
         transferred or otherwise disposed of during said ninety (90) day
         period.

                   -------------------------------
         bankruptcy or appointment of a receiver or trustee for one of the
         Venturers (hereinafter called "Distressed Venturer"), then the other
         Venturers shall have the option to purchase the Venture interest of the
         Distressed Venturer, and Distressed Venturer or its representative
         shall, upon proper exercise of said option, sell to the other Venturer
         such Distressed Venturer's Venture interest; provided however, that
         such option shall not arise with respect to a Venturer for whom a
         receiver or trustee has been appointed but for whom no adjudication or
         settlement has occurred unless such action has not been resolved
         favorably to such Venturer within one hundred twenty (120) days after
         appointment of such receiver or trustee. Such option shall be
         exercisable by the other Venturers by notice of exercise any time

         become aware of such action. The other Venturers shall mutually agree
         as to the percentage of the Distressed Venturer's Venture interest each
         shall purchase. If no agreement is reached, each shall have an option
         for a proportionate share of Distressed Venturer's Venture interest
         based upon purchasing Venturer's proportionate interest in the Venture
         without considering Distressed Venturer's interest.

              A.   Determination of Purchase Price by the Ventures. The
                   -----------------------------------------------
         Venturers agree that where the purchase results from a transfer
         pursuant to an offer to sell as provided in Article XII and not because
         of a transfer pursuant to Article XIII, then the purchase price of a
         One Percent (1%) Venture interest shall be the agreed value of such
         interest as reflected initially on Exhibit "A" and as determined from
         time to time by agreement of a majority of the Venturers and recorded
         on a new or amended Exhibit "A" or the minutes of a Venture meeting. It
         is the intention of the Venturers that the value for purposes of this
         Agreement shall be reviewed at least annually. In the event the
         aforesaid valuation has not been reviewed and redetermined within
         twenty-four (24) months preceding an event requiring determination of
         purchase price, then in that event, the purchase price shall be at fair
         market value as determined by an appraiser selected by both the

                                    - 29 -
<PAGE>
 
         selling Venturers and the other Venturers provided both the selling
         Venturers and the other Venturers agree to the purchase price
         determined by the selected appraiser. Otherwise the purchase price
         shall be at fair market value as determined by an average of the
         closest two determinations of a panel of three arbitrators selected in
         the following manner:

                   (1)  One arbitrator selected by the selling Venturer.

                   (2)  One arbitrator selected by the other Venturers.

                   (3)  One arbitrator selected by the two arbitrators

         designated by the selling and the other Venturers. Arbitration shall be
         conducted in accordance with the provisions of Chapter 682 of the
         Florida Statutes or successor statutes as amended from time to time,
         and the determination of fair market value shall be conclusive.

              The purchase price as determined in accordance with the provisions
         of this Article XIV shall be binding upon the Venturers and all
         successors and assigns of the Venturers.

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

                  1.   Of NTGL and MEXCO. The Net Profits and Losses of NTGL and
                       -----------------
MEXCO shall be allocated among their respective equity owners in accordance with
their respective equity ownership of the Interests thereof. To the extent
allowed by applicable law and unless otherwise agreed by the Parties,
distribution of all of the profits of NTGL and MEXCO shall be made to their
respective equity owners at any time by mutual agreement or at least once a year
on or within thirty-five (35) calendar days after the financial statements of
the applicable Company have been audited and either approved by the Parties or
settled definitively by the accountants of the applicable Company, subject to
manifest error on the part of said accountants.

                  2.   Of AenP.
                       -------
                       a.   In consideration for its contributions to AenP, NTGM
shall be given an undivided thirty percent (30%) interest, subject to year-end
adjustment of its Percentage Share, in the Net Profits of AenP, as adjusted
below (the "Adjusted Net Profits"). Adjusted Net Profits shall be defined as the
Net Profits of AenP, provided, however, that for this purpose the Expenses and
Deductions of AenP shall not include: (i) any depreciation or similar expense
associated with any new drip irrigation equipment acquired by AenP with all or
part of the proceeds of the monies contributed by NTGM for such equipment; and
(ii) any interest payable by AenP to any related or unrelated party on account
of any credit extended to or otherwise obtained by AenP.

                       b.   Year End Adjustments. NTGM's percentage share (the
                            --------------------
"Percentage Share") of the Net Profits of AIRC shall be adjusted from the base
thirty percent (30%) figure listed herein on or within 35 business days from the
end of the fiscal year of AenP. The final Percentage Share corresponding to NTGM
shall be computed by a formula:

                       (1)  the numerator of which will be the sum of: (i)
                                ---------
US$2.2 million; plus (ii) the amount of Pick and Pack Costs paid by NTGM to
AenP; and


                                    - 14 -
<PAGE>
 
                       (2)  the denominator of which shall be the sum of: (i)
                                -----------
all monies paid in connection with the growing and cultivation of the Products,
plus (ii) all actual Pick and Pack Costs of AenP.

             B.   LOSSES.  If NTGL or MEXCO incur Losses, the applicable company
                  ------
may borrow the funds needed to cover such Losses if the capital of the
applicable company is not sufficient. If such company cannot borrow sufficient
funds from an unaffiliated party to cover such Losses, then each equity owner
thereof may, but shall not be obligated to, fund its respective percentage of
the funds necessary to cover said Losses. In such event, the lending equity
owner shall be repaid its loan (with interest at the N.Y. Prime Rate) prior to
any distributions being made to the respective equity owners. If AenP incurs
losses in excess of the capital contributions of NTGM and AIRC to AenP, NTGM
shall fund 30% of such losses, subject to adjustment as provided in Section VI
A.2.b.

                                 MARKETING AGREEMENT



              AGREEMENT, made this 1st day of September, 1988, by and
         between HARLLEE-GARGIULO INC., a Florida corporation, hereinafter
         referred to as "COMPANY," and GARGIULO INC., hereinafter referred
         to as "SALES AGENT."

              WHEREAS, COMPANY is engaged in the packing of tomatoes, and

              WHEREAS, the SALES AGENT is currently acting as an
         independent sales representative of the COMPANY, and

              WHEREAS, the parties desire to affirm such relationship for a
         one year period;

              NOW, THEREFORE, in consideration of the foregoing and of the
         joint and mutual promises and undertakings, herein contained, and
         for other good and valuable considerations, the parties do hereby
         agree as follows:

              1.   Exclusive Sales Representative:  THE COMPANY hereby
                   ------------------------------
         retains SALES AGENT as its exclusive sales agent for the COMPANY'S
         tomatoes for a period of one (1) year from the date of this
         Agreement.  This Agreement shall automatically renew on a year to
         year basis absent its termination by either party in accordance
         with Paragraph 6 hereof.

              2.   Agent's Compensation:   THE COMPANY shall pay the SALES
                   --------------------
         AGENT a commission of twenty cents ($.20) per twenty-five pound
         box of regular tomatoes and twenty-five cents ($.25) per flat of
         cherry tomatoes sold by SALES AGENT on behalf of COMPANY.  COMPANY
<PAGE>
 
         agrees to pay sales agent's full commission to SALES AGENT when
         SALES AGENT sells tomatoes through a secondary broker.  COMPANY
         further agrees to pay such secondary broker its full brokerage fee
         or commission.  A "sale" for purposes of this Agreement shall
         occur upon receipt of the sales price by the COMPANY.

              3.   Expenses:  The SALES AGENT shall pay all of its expenses
                   --------   
         in connection with the selling of COMPANY's tomatoes in accordance
         with the established custom by and between COMPANY and SALES
         AGENT.

              4.   Customer's Failure to Pay Account:  In the event of
                   ---------------------------------
         nonpayment of a customer's account resulting in a loss to the
         COMPANY, the SALES AGENT shall not be liable for such loss, but
         does hereby agree to devote his best efforts to obtain the full
         satisfaction of such account by the delinquent customer.  SALES
         AGENT or secondary broker shall not receive any commission as
         provided herein for any portion of an unsatisfied account.

              5.   SALES AGENT's Status:  It is further agreed by and
                   --------------------
         between the parties hereto that the SALES AGENT shall perform
         under this Agreement as an independent agent, and nothing herein
         contained shall be construed to be inconsistent with the
         relationship or status.  SALES AGENT shall be responsible for all
         sub-agents and all other selling expenses.

              6.   Termination of Agreement:  If either party shall desire
                   ------------------------
         to terminate this Agreement it shall deliver notice of such
         termination at least 1 year prior to the end of the Agreement.


                                         -2-
<PAGE>
 
         Upon the end of such year, this Agreement shall be null and void.
         SALES AGENT shall continue its best efforts until the end of this
         Agreement in accordance with Paragraph 7 hereof and the COMPANY
         shall pay over to the SALES AGENT any commissions accruing to the
         SALES AGENT prior to the termination of the Agreement.  It is
         further agreed that upon the termination of this Agreement by
         either party, SALES AGENT shall be entitled to purchase the
         interest of the COMPANY in the BHN Joint Venture at a price equal
         to the cumulative investment of the COMPANY in the joint venture.
         Said purchase price shall be paid in thirty-six (36) equal
         installments beginning thirty (30) days after termination of this

         relevant information and in accordance with Section 7 of the Plan,
         the fair market value of the Common Stock; (iii) to determine the
         exercise price per share of Options to be granted, which exercise
         price shall be determined in accordance with Section 7 of the
         Plan; (iv) to determine the Employees or Consultants to whom, and

         necessary or advisable for the administration of the Plan.

                   (c)  Effect of Committee's Decision.  All decisions,
                        ------------------------------
         determinations and interpretations of the Committee shall be final
         and binding on all Optionees and any other holders of any Options
         granted under the Plan.

              5.   Eligibility.
                   -----------

                   (a)  Options may be granted to Employees, Consultants
         and Outside Directors provided that (i) Incentive Stock Options
         may be granted only to Employees and (ii) Options may be granted
         to Outside Directors only in accordance with the provisions of
         Section 5(b) hereof.  Subject to Section 5(b) with respect to
         Outside Directors, an Employee, Consultant or Outside Director who
         has been granted an option may, if such Employee, Consultant or
         Outside Director is otherwise eligible, be granted additional
         Options.

                   (b)  All grants of Options to Outside Directors under
         this Plan shall be automatic and non-discretionary and shall be
         made strictly in accordance with the following provisions:

                        (i)  No person shall have any discretion to select
         which Outside Directors shall be granted Options or to determine
         the number of shares to be covered by Options granted to Outside
         Directors; provided, however, that nothing in this Plan shall be
         construed to prevent an Outside Director from declining to receive
         an Option under this Plan.

                        (ii)  Each Outside Director who is first elected to
         the Board of Directors after the adoption of this Plan (other than
         an Outside Director who was previously a director of Calgene,
         Inc.) shall be automatically granted on the date of such election
         (whether by the stockholders or by the Board of Directors) an
         Option to purchase 10,000 Shares (subject to adjustment as
         provided in Section 10).  On the date of the Annual Stockholders
         Meeting in each calendar year commencing in 1997, each Outside
         Director who is elected or re-elected at that meeting shall be
         automatically granted an Option to purchase 3,000 Shares (subject
         to adjustment as provided in Section 10); except that no such
         automatic annual grant shall be made to an Outside Director who is
         first elected to the Board of Directors at such Annual Meeting
         (and therefore receives an automatic grant of a 10,000 Share

                                      -4-
<PAGE>
 
         Option) or who was first elected by the Board of Directors within
         three months prior to such Annual Meeting.

                        (iii)  The terms of each Option granted under this
         Section 5(b) shall be as follows:

                             (A)  the term of the Option shall be ten
                        years;

                             (B)  the Option shall become exercisable
                        cumulatively with respect to one twelfth of the
                        Shares on the last day of each month following the
                        date of grant; provided, however, that in no event
                        shall any Option be exercisable prior to obtaining
                        stockholder approval of the Plan.

                             (C)  the exercise price per share of Common
                        Stock shall be 100% of the Fair Market Value on the
                        date of grant of the Option.

                   (c)  Each Option shall be designated in the written
         option agreement as either an Incentive Stock Option or a
         Nonstatutory Stock Option.  However, notwithstanding such
         designations, to the extent that the aggregate fair market value
         of the Shares with respect to which Options designated as
         Incentive Stock Options are exercisable for the first time by any
         Optionee during any calendar year (under all plans of the Company)
         exceeds $100,000, such Options shall be treated as Nonstatutory
         Stock Options.  For purposes of this Section 5(c), Options shall
         be taken into account in the order in which they were granted, and
         the fair market value of the Shares shall be determined as of the
         time the Option with respect to such Shares is granted.

                   (d)  The Plan shall not confer upon any Optionee any
         right with respect to continuation of employment by or the
         rendition of services to the Company, nor shall it interfere in
         any way with his or her right or the Company's right to terminate
         his or her employment or services at any time, with or without
         cause.

              6.   Term of Plan.  The Plan shall become effective upon the
                   ------------
         earlier to occur of its adoption by the Board of Directors or its
         approval by vote of the holders of a majority of the outstanding
         shares of the Company entitled to vote on the adoption of the
         Plan.  It shall continue in effect for a term of ten (10) years
         unless sooner terminated under Section 14 of the Plan.

              7.   Exercise Price and Consideration.
                   --------------------------------

                   (a)  The per Share exercise price for the Shares to be
         issued pursuant to exercise of an Option shall be such price as is
         determined by the Board, but shall be subject to the following:

                        (i)  In the case of an Incentive Stock Option
         granted to any Employee, the per Share exercise price shall be no
         less than 100% of the fair market value per Share on the date of
         grant, but if granted to an Employee who, at the time of the grant
         of such Incentive Stock Option, owns stock representing more than
         ten percent (10%) of the voting power of all classes of stock of
         the Company or any Parent or Subsidiary, the per Share exercise
         price shall be no less than 110% of the fair market value per
         Share on the date of grant.

                        (ii) In the case of a Nonstatutory Stock Option
         granted to any person other than an Outside Director, the per
         Share exercise price shall be no less than 85% of the fair market
         value per Share on the date of grant, but if granted to a person
         who, at the time of the grant of such Option, owns stock
         representing more than ten percent (10%) of the voting power of
         all classes of stock of the Company or any Parent or Subsidiary,
         the per Share exercise price shall be no less than 110% of the
         fair market value per Share on the date of the grant.  The
         exercise price of Options granted pursuant to Section 5(b) shall
         be 100% of the Fair Market Value on the date of grant of the
         Option.

                   For purposes of this Section 7(a), in the event that an
         Option is amended to reduce the exercise price, the date of grant
         of such Option shall thereafter be considered to be the date of
         such amendment.

                   (b)  The fair market value shall be determined by the
         Board in its discretion.  

                   (c)  The consideration to be paid for the Shares to be
         issued upon exercise of an Option, including the method of
         payment, shall be determined by the Committee (and, in the case of
         an Incentive Stock Option, shall be determined at the time of
         grant), and may consist entirely of (i) cash, (ii) check, (iii)
         the Optionee's personal interest bearing full recourse promissory
         note with such terms and provisions as the Board of Directors may
         authorize, provided that no person who is not an employee of the
         Company may purchase Shares with a promissory note, (iv) other
         Shares of Common Stock which (x) either have been owned by the
         Optionee for more than six (6) months on the date of surrender or
         were not acquired directly or indirectly from the Company, and (y)
         have a fair market value on the date of surrender (determined

                                      -6-
<PAGE>
 
         without regard to any limitations on transferability imposed by
         securities laws) equal to the aggregate exercise price of the
         Shares as to which said Option shall be exercised, (v) having the
         Company retain from the total number of Shares as to which the
         Option is exercised that number of Shares having a fair market
         value on the date of exercise equal to the exercise price for the
         total number of Shares as to which the Option is exercised;
         provided however that the method of exercise set forth in this
         clause (v) shall not be permitted unless the Committee so permits
         at the time of exercise; (vi) delivery of a properly executed
         exercise notice together with irrevocable instructions to a broker
         to promptly deliver to the Company the amount of sale or loan
         proceeds required to pay the exercise price; (vii) any combination
         of such methods of payment; or (viii) such other consideration and
         method of payment for the issuance of Shares to the extent
         permitted under applicable laws.

              8.   Options.
                   -------

                   (a)  Term of Option.  The term of each Option shall be
                        --------------
         ten (10) years from the date of grant thereof or such shorter term
         as may be provided in the Option agreement.  However, in the case
         of an Option granted to an Optionee who, at the time the Option is
         granted, owns stock representing more than ten percent (10%) of
         the voting power of all classes of stock of the Company or any
         Parent or Subsidiary, the term of the Option shall be five (5)
         years from the date of grant thereof or such shorter time as may
         be provided in the Option agreement.

                   (b)  Exercise of Option.
                        ------------------

                        (i)  Procedure for Exercise; Rights as a
                             -----------------------------------
         Shareholder.  Any Option granted hereunder (other than an Option
         -----------
         granted pursuant to Section 5(b) shall be exercisable at such
         times and under such conditions as determined by the Committee,
         including performance criteria with respect to the Company and/or
         the Optionee, and as shall be permissible under the terms of the
         Plan.

                        An Option may not be exercised for a fraction of a
         Share.

                        An Option shall be deemed to be exercised when
         written notice of such exercise has been given to the Company in
         accordance with the terms of the Option by the person entitled to
         exercise the Option and full payment for the Shares with respect
         to which the Option is exercised has been received by the Company.
         Full payment may, as authorized by the Board, consist of any
         consideration and method of payment allowable under Section 7 of
         the Plan.  Until the issuance (as evidenced by the appropriate

                                      -7-
<PAGE>
 
         entry on the books of the Company or of a duly authorized transfer
         agent of the Company) of the stock certificate evidencing such
         Shares, no right to vote or receive dividends or any other rights
         as a shareholder shall exist with respect to the Optioned Stock,
         notwithstanding the exercise of the Option.  The Company shall
         issue (or cause to be issued) such stock certificate promptly upon
         exercise of the Option.  In the event that the exercise of an
         Option is treated in part as the exercise of an Incentive Stock
         Option and in part as the exercise of a Nonstatutory Stock Option
         pursuant to Section 5(b), the Company shall issue a separate stock
         certificate evidencing the Shares treated as acquired upon
         exercise of an Incentive Stock Option and a separate stock
         certificate evidencing the Shares treated as acquired upon
         exercise of a Nonstatutory Stock Option and shall identify each
         such certificate accordingly in its stock transfer records.  No
         adjustment will be made for a dividend or other right for which
         the record date is prior to the date the stock certificate is
         issued, except as provided in Section 11 of the Plan.

                        Exercise of an Option in any manner shall result in
         a decrease in the number of Shares which thereafter may be
         available, both for purposes of the Plan and for sale under the
         Option, by the number of Shares as to which the Option is
         exercised.

                        (ii) Termination of Status as an Employee,
                             ------------------------------------
         Consultant or Outside Director.  In the event of termination of an
         ------------------------------
         Optionee's Continuous Status as an Employee, Consultant or Outside
         Director (as the case may be) for any reason whatever, such
         Optionee may, but only within such period of time as provided in
         the Option Agreement, after the date of such termination (but in
         no event later than the date of expiration of the term of such
         Option as set forth in the Option agreement), exercise the Option
         to the extent that such Employee, Consultant or Outside Director
         was entitled to exercise the Option at the date of such
         termination, or if such Employee, Consultant or Outside Director
         does not exercise such Option (which such Employee, Consultant or
         Outside Director was entitled to exercise) within the time
         specified herein, the Option shall terminate.

              9.   Non-Transferability of Options.  Options may not be
                   ------------------------------
         sold, pledged, assigned, hypothecated, transferred, or disposed of
         in any manner other than by will or by the laws of descent or
         distribution or pursuant to a qualified domestic relations order
         as defined by the Code or the rules thereunder.  An Option may be
         exercised, during the lifetime of the Optionee, only by the
         Optionee or a transferee pursuant to such qualified domestic
         relations order.

              10.  Adjustments Upon Changes in Capitalization or Merger.
                   ----------------------------------------------------

                   (a)  Subject to any required action by the shareholders
         of the Company, the number of shares of Common Stock which have
         been authorized for issuance under the Plan but as to which no
         Options have yet been granted or which have been returned to the
         Plan upon cancellation or expiration of an Option, the number of
         shares of Common Stock referred to in Sections 4(a) and 5(b) of
         the Plan, and the number of shares of Common Stock subject to each
         outstanding Option, as well as the price per share of Common Stock
         covered by each such outstanding option, shall be proportionately
         adjusted for any increase or decrease in the number  of issued
         shares of Common Stock resulting from a stock split, reverse stock
         split, stock dividend, combination or reclassification of the
         Common Stock of the Company or the payment of a stock dividend
         with respect to the Common Stock.  Except as expressly provided
         herein, no issuance by the Company of shares of stock of any
         class, shall affect, and no adjustment by reason thereof shall be
         made with respect to, the number or price of shares of Common
         Stock subject to an Option.

                   (b)  In the event of the proposed dissolution or
         liquidation of the Company, the Option will terminate immediately
         prior to the consummation of such proposed action, unless
         otherwise provided by the Committee.  The Committee may, in the
         exercise of its sole discretion in such instances, declare that
         any Option shall terminate as of a date fixed by the Committee and
         give each Optionee the right to exercise his or her Option as to
         all or any part of the Optioned Stock, including Shares as to
         which the Option would not otherwise be exercisable.

                   (c)  In the event of a proposed sale of all or
         substantially all of the assets of the Company, or the merger of
         the Company with or into another corporation, the Option shall be
         assumed or an equivalent option shall be substituted by such
         successor corporation or a parent or subsidiary of such successor
         corporation, unless the successor corporation refuses to assume
         the Option or substitute an equivalent option, in which case the
         Optionee shall have the right to exercise the Option as to all of
         the Optioned Stock, including Shares as to which the Option would
         not otherwise be exercisable.  The Option shall be deemed to be
         assumed if, following the sale of assets or merger, the Option
         confers the right to purchase, for each share of Optioned Stock
         subject to the Option immediately prior to the sale of assets or
         merger, the consideration (whether stock, cash or other securities
         or property) received in the sale of assets or merger by holders
         of Common Stock for each share of Common Stock held on the
         effective date of the sale of assets or merger (and if such
         holders were offered a choice of consideration, the type of
         consideration chosen by the holders of the largest number of the

                                      -9-
<PAGE>
 
         outstanding shares of Common Stock); provided, however, that if
         such consideration received in the sale of assets or merger was
         not solely common stock of the successor corporation or its
         Parent, the Committee may, with the consent of the successor
         corporation and the Optionee, provide for the per Share
         consideration to be received upon exercise of the Option to be
         solely Common Stock of the successor corporation or its Parent
         equal in fair market value (as of the effective date of the sale
         of assets or merger) to the per share consideration received by
         holders of Common Stock in the sale of assets or merger.  If the
         Committee makes an Option fully exercisable in lieu of assumption
         or substitution in the event of a merger or sale of assets, the
         Committee shall notify the Optionee that the Option shall be fully
         exercisable for a period of fifteen (15) days from the date of
         such notice, and the Option will terminate upon the expiration of
         such period.

              11.  Time of Granting Options.  The date of grant of an
                   ------------------------
         Option shall, for all purposes, be the date on which the Committee
         (or its delegate the President as permitted herein) makes the
         determination granting such Option.  Notice of the determination
         shall be given to each Employee, Consultant or Outside Director to
         whom an Option is so granted within a reasonable time after the
         date of such grant.

              12.  Amendment and Termination of the Plan.
                   -------------------------------------

                   (a)  Amendment and Termination.  The Committee may amend
                        -------------------------
         or terminate the Plan from time to time in such respects as the
         Committee may deem advisable; provided that , to the extent
         necessary to comply with Rule 16b-3 or with Section 422A of the
         Code (or any other successor or applicable law or regulation), the
         Company shall obtain stockholder approval of any Plan amendment in
         such a manner and to such a degree as is required by the
         applicable law, rule or regulation.  Notwithstanding the
         foregoing, neither the provisions of Section 5(b), nor any other
         provisions pertaining to the automatic option grants to Outside
         Directors, shall be amended more than once every six months, other
         than to comport with changes in the Code, the Employee Retirement
         Income Security Act (if applicable) or the rules thereunder.

                   (b)  Effect of Amendment or Termination.  Any such
                        ----------------------------------
         amendment or termination of the Plan shall not affect Options
         already granted and such Options shall remain in full force and
         effect as if this Plan had not been amended or terminated, unless
         mutually agreed otherwise between the Optionee and the Committee,
         which agreement must be in writing and signed by the Optionee and
         the Company.

              13.  Conditions Upon Issuance of Shares.  Shares shall not be
                   ----------------------------------
         issued pursuant to the exercise of an Option unless the exercise
         of such Option and the issuance and delivery of such Shares
         pursuant thereto shall comply with all relevant provisions of law,
         including, without limitation, the Securities Act of 1933, as
         amended, the Exchange Act, the rules and regulations promulgated
         thereunder, and the requirements of any stock exchange upon which
         the Shares may then be listed, and shall be further subject to the
         approval of counsel for the Company with respect to such
         compliance.

                   As a condition to the exercise of an Option, the Company
         may require the person exercising such Option to represent and
         warrant at the time of any such exercise that the Shares are being
         purchased only for investment and without any present intention to
         sell or distribute such Shares if, in the opinion of counsel for
         the Company, such a representation is required by any of the
         aforementioned relevant provisions of law.

              14.  Reservation of Shares.  The Company, during the term of
                   ---------------------
         this Plan, will at all times reserve and keep available such
         number of Shares as shall be sufficient to permit the exercise of
         all Options outstanding under the Plan.

                   The inability of the Company to obtain authority from
         any regulatory body having jurisdiction, which authority is deemed
         by the Company's counsel to be necessary to the lawful issuance
         and sale of any Shares hereunder, shall relieve the Company of any
         liability in respect of the failure to issue or sell such Shares
         as to which such requisite authority shall not have been obtained.

              15.  Option Agreements.  Options shall be evidenced by
                   -----------------
         written Option agreements in such form as the Committee shall
         approve.

              16.  Information to Optionees.  To the extent required by
                   ------------------------
         applicable law, the Company shall provide to each Optionee, during
         the period for which such Optionee has one or more Options
         outstanding, copies of all annual reports and other information
         which are provided to all shareholders of the Company.

                               CHANGE OF CONTROL
                             EMPLOYMENT AGREEMENT
                             --------------------


     AGREEMENT by and between Calgene, Inc., a Delaware corporation (the
"Company") and Roger Salquist (the "Executive"), dated as of the 19th day of
July, 1995.


     The Board of Directors of the Company (the "Board"), has determined that it
is in the best interests of the Company and its shareholders to assure that the
Company will have the continued dedication of the Executive, notwithstanding the
possibility, threat or occurrence of a Change of Control (as defined below) of
the Company. The Board believes it is imperative to diminish the inevitable
distraction of the Executive by virtue of the personal uncertainties and risks
created by a pending or threatened Change of Control and to encourage the
Executive's full attention and dedication to the Company currently and in the
event of any threatened or pending Change of Control, and to provide the
Executive with compensation and benefits arrangements upon a Change of Control
which ensure that the compensation and benefits expectations of the Executive
will be satisfied and which are competitive with those of other corporations.
Therefore, in order to accomplish these objectives, the Board has caused the
Company to enter into this Agreement
<PAGE>
 
     NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:


     l.   Certain Definitions.  (a) The "Effective Date" shall mean the first 
          -------------------
date during the Change of Control Period (as defined in Section 1(b)) on which a
Change of Control (as defined in Section 2) occurs. Anything in this Agreement
to the contrary notwithstanding, if a Change of Control occurs and if the
Executive's employment with the Company is terminated prior to the date on which
the Change of Control occurs, and if it is reasonably demonstrated by the
Executive that such termination of employment (i) was at the request of a third
party who has taken steps reasonably calculated to effect a Change of Control or
(ii) otherwise arose in connection with or anticipation of a Change of Control,
then for all purposes of this Agreement the "Effective Date" shall mean the date
immediately prior to the date of such termination of employment.


     (b)  The "Change of Control Period" shall mean the period commencing on the
date hereof and ending on the third anniversary of the date hereof; provided,
however, that commencing on the date one year after the date hereof, and on each
annual anniversary of such date (such date and each annual anniversary thereof
shall be hereinafter referred to as the "Renewal Date"), unless previously
terminated, the Change of Control Period shall be automatically extended so as
to terminate three years from such Renewal Date,

                                      -2-
<PAGE>
 
unless at least 60 days prior to the Renewal Date the Company shall give notice
to the Executive that the Change of Control Period shall not be so extended.


     2.   Change of Control.  For the purpose of this Agreement, a "Change of 
          -----------------
Control" shall mean:


     (a)  The acquisition by any individual, entity or group (within the meaning
of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act")) (a "Person") of beneficial ownership (within the
meaning of Rule 13d-3 promulgated under the Exchange Act) of 40% or more of
either (i) the then outstanding shares of common stock of the Company (the
"Outstanding Company Common Stock") or (ii) the combined voting power of the
then outstanding voting securities of the Company entitled to vote generally in
the election of directors (the "Outstanding Company Voting Securities");
provided, however, that for purposes of this subsection (a), the following
acquisitions shall not constitute a Change of Control: (i) any acquisition by
any employee benefit plan (or related trust) sponsored or maintained by the
Company or any corporation controlled by the Company or (ii) any acquisition by
any corporation pursuant to a transaction which complies with clauses (i), (ii)
and (iii) of subsection (c) of this Section 2; or

                                      -3-
<PAGE>
 
     (b)  Individuals who, as of the date hereof, constitute the Board (the
"Incumbent Board") cease for any reason to constitute at least a majority of the
Board; provided, however, that any individual becoming a director subsequent to
the date hereof whose election, or nomination for election by the Company's
shareholders, was approved by a vote of at least a majority of the directors
then comprising the Incumbent Board shall be considered as though such
individual were a member of the Incumbent Board, but excluding, for this
purpose, any such individual whose initial assumption of office occurs as a
result of an actual or threatened election contest with respect to the election
or removal or directors or other actual or threatened solicitation of proxies or
consents by or on behalf of a Person other than the Board; or


     (c)  Approval by the shareholders of the Company of a reorganization,
merger or consolidation or sale or other disposition of all or substantially all
of the assets of the Company (a "Business Combination"), in each case, unless,
immediately following such Business Combination, (i) all or substantially all of
the individuals and entities who were the beneficial owners, respectively, of
the Outstanding Company Common Stock and Outstanding Company Voting Securities
immediately prior to such Business Combination beneficially own, directly or
indirectly, more than 60% of, respectively, the then outstanding shares of
common stock and the combined voting power of the then

                                      -4-
<PAGE>
 
outstanding voting securities entitled to vote generally in the election of
directors, as the case may be, of the corporation resulting from such Business
Combination (including, without limitation, a corporation which as a result of
such transaction owns the Company or all or substantially all of the Company's
assets either directly or through one or more subsidiaries) in substantially the
same proportions as their ownership, immediately prior to such Business
Combination of the Outstanding Company Common Stock and Outstanding Company
Voting Securities, as the case may be, (ii) no Person (excluding any employee
benefit plan (or related trust) of the Company or such corporation resulting
from such Business Combination) beneficially owns, directly or indirectly, 40%
or more of, respectively, the then outstanding shares of common stock of the
corporation resulting from such Business Combination or the combined voting
power of the then outstanding voting securities of such corporation except to
the extent that such ownership existed prior to the Business Combination and
(iii) at least a majority of the members of the board of directors of the
corporation resulting from such Business Combination were members of the
Incumbent Board at the time of the execution of the initial agreement, or of the
action of the Board, providing for such Business Combination;


     (d)  Approval by the shareholders of the Company of a complete liquidation
or dissolution of the Company; or

                                      -5-

     (e)  The closing of the transactions contemplated by the Letter of Intent
dated June 27, 1995 between the Company and Monsanto Company (the "Monsanto
Letter of Intent").


     3.   Employment Period.  The Company hereby agrees to continue the 
          -----------------
Executive in its employ, and the Executive hereby agrees to remain in the employ
of the Company subject to the terms and conditions of this Agreement, for the
period commencing on the Effective Date and ending on the third anniversary of
such date (the "Employment Period")


     4.   Terms of Employment.  (a) Position and Duties. (i) During the 
          -------------------       -------------------
Employment Period, (A) the Executive's position (including status, offices,
titles and reporting requirements), authority, duties and responsibilities shall
be at least commensurate in all material respects with the most significant of
those held, exercised and assigned to the Executive at any time during the 120-
day period immediately preceding the Effective Date, except as otherwise
contemplated by the Monsanto Letter of Intent, and (B) the Executive's services
shall be performed at the location where the Executive was employed immediately
preceding the Effective Date or any office or location less than 50 miles from
such location.

     (ii)  During the Employment Period, and excluding any periods of vacation
and sick leave to which the Executive is entitled, the Executive agrees to
devote reasonable attention and time during normal business hours to the
business and affairs of the Company and, to the extent necessary to discharge
the responsibilities assigned to the Executive hereunder, to use the Executive's
reasonable efforts to perform faithfully and efficiently such responsibilities.
During the Employment Period it shall not be a violation of this Agreement for
the Executive to (A) serve on corporate, civic or charitable boards or
committees, or (B) deliver lectures and fulfill speaking engagements, so long as
such activities do not significantly interfere with the Executive's
responsibilities under this Agreement. It is expressly understood and agreed
that to the extent that any such activities have been conducted by the Executive
prior to the Effective Date, the continued conduct of such activities (or the
conduct of activities similar in nature and scope thereto) subsequent to the
Effective Date shall not thereafter be deemed to interfere with the performance
of the Executive's responsibilities to the Company.


     (b)  Compensation.   (i)  Base Salary.  During the Employment Period, the 
          ------------         -----------
Executive shall receive an annual base salary ("Annual Base Salary"), which
shall be paid at a monthly rate, at least equal to twelve times the highest
monthly base salary paid or payable, including any base salary which has been
earned but

                                      -7-
<PAGE>
 
deferred, to the Executive by the Company and its affiliated companies in
respect of the twelve-month period immediately preceding the month in which the
Effective Date occurs. During the Employment Period, the Annual Base Salary
shall be reviewed no more than 12 months after the last salary increase awarded
to the Executive prior to the Effective Date and thereafter at least annually.
Any increase in Annual Base Salary shall not serve to limit or reduce any other
obligation to the Executive under this Agreement. Annual Base Salary shall not
be reduced after any such increase and the term Annual Base Salary as utilized
in this Agreement shall refer to Annual Base Salary as so increased. As used in
this Agreement, the term "affiliated companies" shall mean any direct or
indirect subsidiary of the Company.


     (ii)  Annual Bonus.  In addition to Annual Base Salary, the Executive 
           ------------
shall be awarded, for each fiscal year ending during the Employment Period, an
annual bonus (the "Annual Bonus") in cash at least equal to the average bonus
paid to the Executive for the last three full fiscal years prior to the
Effective Date (the "Recent Average Bonus"). Each such Annual Bonus shall be
paid no later than the end of the third month of the fiscal year next following
the fiscal year for which the Annual Bonus is awarded, unless the Executive
shall elect to defer the receipt of such Annual Bonus.

     (iii)  Savings and Retirement Plans.  During the Employment Period, the 
            ----------------------------
Executive shall be entitled to participate in all savings and retirement plans,
practices, policies and programs applicable generally to other senior executives
of the Company, but in no event shall such plans, practices, policies and
programs provide the Executive with savings opportunities and retirement benefit
opportunities, in each case, less favorable, in the aggregate, than the most
favorable of those provided by the Company for the Executive under such plans,
practices, policies and programs as in effect at any time during the 120-day
period immediately preceding the Effective Date or if more favorable to the
Executive, those provided generally at any time after the Effective Date to
other senior executives of the Company.


     (iv)  Welfare Benefit Plans.  During the Employment Period, the Executive 
           ---------------------
and/or the Executive's family, as the case may be, shall be eligible for
participation in and shall receive all benefits under welfare benefit plans,
practices, policies and programs provided by the Company (including, without
limitation, medical, prescription, dental, disability, salary continuance,
employee life, group life, accidental death and travel accident insurance plans
and programs) to the extent applicable generally to other senior executives of
the Company, but in no event shall such plans, practices, policies and programs
provide the Executive with benefits which are less favorable, in the aggregate,
than the

                                      -9-
<PAGE>
 
most favorable of such plans, practices, policies and programs in effect for the
Executive at any time during the 120-day period immediately preceding the
Effective Date or, if more favorable to the Executive, those provided generally
at any time after the Effective Date to other senior executives of the Company.


     (v)   Expenses.  During the Employment Period, the Executive shall be 
           --------
entitled to receive prompt reimbursement for all reasonable expenses incurred by
the Executive in accordance with the policies, practices and procedures of the
Company in effect for the Executive at any time during the 120-day period
immediately preceding the Effective Date.


     (vi)  Vacation.  During the Employment Period, the Executive shall be 
           --------
entitled to paid vacation in accordance with the most favorable plans, policies,
programs and practices of the Company as in effect for the Executive at any time
during the 120-day period immediately preceding the Effective Date or, if more
favorable to the Executive, as in effect generally at any time thereafter with
respect to other senior executives of the Company.


     5.    Termination of Employment.  
           -------------------------


          (a)  Death or Disability.  The Executive's employment shall 
               -------------------
terminate automatically upon the Executive's death during

                                      -10-
<PAGE>
 
the Employment Period. If the Company determines in good faith that the
Disability of the Executive has occurred during the Employment Period (pursuant
to the definition of Disability set forth below), it may give to the Executive
written notice in accordance with Section 11(b) of this Agreement of its
intention to terminate the Executive's employment. In such event, the
Executive's employment with the Company shall terminate effective on the 30th
day after receipt of such notice by the Executive (the "Disability Effective
Date"), provided that, within the 30 days after such receipt, the Executive
shall not have returned to full-time performance of the Executive's duties. For
purposes of this Agreement, "Disability" shall mean the absence of the Executive
from the Executive's duties with the Company on a full-time basis for 180
consecutive business days as a result of incapacity due to mental or physical
illness which is determined to be total and permanent by a physician selected by
the Company or its insurers and acceptable to the Executive or the Executive's
legal representative.


     (b)  Cause.  The Company may terminate the Executive's employment during 
          -----
the Employment Period for Cause. For purposes of this Agreement, "Cause" shall
mean the willful engaging by the Executive in illegal conduct or gross
misconduct which is materially and demonstrably injurious to the Company. The
cessation of employment of the Executive shall not be deemed to be

                                      -11-
<PAGE>
 
for Cause unless and until there shall have been delivered to the Executive a
copy of a resolution duly adopted by the affirmative vote of not less than 
three-quarters of the entire membership of the Board at a meeting of the Board
called and held for such purpose (after reasonable notice is provided to the
Executive and the Executive is given an opportunity, together with counsel, to
be heard before the Board), finding that, in the good faith opinion of the
Board, the Executive is guilty of an act or omission constituting Cause.


     (c)  Good Reason.  The Executive's employment may be terminated by the 
          -----------
Executive for Good Reason. For purposes of this Agreement, "Good Reason" shall
mean:


          (i)  the assignment to the Executive of any duties inconsistent in any
     respect with the Executive's position (including status, offices, titles
     and reporting requirements), authority, duties or responsibilities as
     contemplated by Section 4(a) of this Agreement, except as contemplated by
     the Monsanto Letter of Intent, or any other action by the Company which
     results in a diminution in such position, authority, duties or
     responsibilities, excluding for this purpose an isolated, insubstantial and
     inadvertent action not taken in bad faith and which is remedied by the

                                      -12-
<PAGE>
 
     Company promptly after receipt of notice thereof given by the Executive;


          (ii)   any failure by the Company to comply with any of the provisions
     of Section 4(b) of this Agreement, other than an isolated, insubstantial
     and inadvertent failure not occurring in bad faith and which is remedied by
     the Company promptly after receipt of notice thereof given by the
     Executive;


          (iii)  the Company's requiring the Executive to be based at any office
     or location other than as provided in Section 4(a)(i)(B) hereof or the
     Company's requiring the Executive to travel on Company business to a
     substantially greater extent than required immediately prior to the
     Effective Date;


          (iv)   any purported termination by the Company of the Executive's
     employment otherwise than as expressly permitted by this Agreement; or


          (v)    any failure by the Company to comply with and satisfy Section
     10(c) of this Agreement.
     

                                      -13-
<PAGE>
 
For purposes of this Section 5(c), any good faith determination of "Good Reason"
made by the Executive shall be conclusive. Anything in this Agreement to the
contrary notwithstanding, a termination by the Executive for any reason during
the 90-day period immediately following the six-month anniversary of the
Effective Date or during the 30-day period immediately prior to the expiration
of the Employment Period shall be deemed to be a termination for Good Reason for
all purposes of this Agreement.


     (d)  Notice of Termination.  Any termination by the Company for Cause, or 
          ---------------------
by the Executive for Good Reason, shall be communicated by Notice of Termination
to the other party hereto given in accordance with Section 11(b) of this
Agreement. For purposes of this Agreement, a "Notice of Termination" means a
written notice which (i) indicates the specific termination provision in this
Agreement relied upon, (ii) to the extent applicable, sets forth in reasonable
detail the facts and circumstances claimed to provide a basis for termination of
the Executive's employment under the provision so indicated and (iii) if the
Date of Termination (as defined below) is other than the date of receipt of such
notice, specifies the termination date (which date shall be not more than thirty
days after the giving of such notice). The failure by the Executive or the
Company to set forth in the Notice of Termination any fact or circumstance which
contributes to a showing of Good Reason or Cause shall not waive

                                      -14-
<PAGE>
 
any right of the Executive or the Company, respectively, hereunder or preclude
the Executive or the Company, respectively, from asserting such fact or
circumstance in enforcing the Executive's or the Company's rights hereunder.


          (e)  Date of Termination.  "Date of Termination" means (i) if the 
               -------------------
Executive's employment is terminated by the Company for Cause, or by the
Executive for Good Reason, the date of receipt of the Notice of Termination or
any later date specified therein, as the case may be, (ii) if the Executive's
employment is terminated by the Company other than for Cause or Disability, the
date on which the Company notifies the Executive of such termination and (iii)
if the Executive's employment is terminated by reason of death or Disability,
the date of death of the Executive or the Disability Effective Date, as the case
may be.


          6.   Obligations of the Company upon Termination.
               -------------------------------------------


               (a)  Good Reason; Other than for Cause, Death or Disability. If,
                    ------------------------------------------------------
during the Employment Period, the Company shall terminate the Executive's
employment other than for Cause or

                                      -15-
<PAGE>
 
Disability, or the Executive shall terminate employment for Good Reason:


     (i)  The Company shall pay to the Executive in a lump sum in cash within 30
days after the Date of Termination the aggregate of the following amounts:


          A.   The sum of (l) the Executive's Annual Base Salary through the
     Date of Termination to the extent not previously paid, (2) the product of
     (x) the Recent Average Bonus and (y) a fraction, the numerator of which is
     the number of days in the current fiscal year through the Date of
     Termination, and the denominator of which is 365 and (3) any compensation
     previously deferred by the Executive (together with any accrued interest or
     earnings thereon) and any accrued vacation pay, in each case to the extent
     not previously paid (the sum of the amounts described in clauses (1), (2),
     and (3) shall be hereinafter referred to as the "Accrued Obligations"); and


          B.   the amount equal to the product of (1) three and (2) the sum of
     (x) the Executive's Annual Base Salary and (y) the Recent Average Bonus.
     

                                      -16-
<PAGE>
 
     (ii)  For one year after the Executive's Date of Termination, or such
longer period as may be provided by the terms of the appropriate plan, program,
practice or policy, the Company shall continue benefits to the Executive and/or
the Executive's family at least equal to those which would have been provided to
them in accordance with the plans, programs, practices and policies described in
Section 4(b)(iv) of this Agreement if the Executive's employment had not been
terminated or, if more favorable to the Executive, as in effect generally at any
time thereafter with respect to other senior executives of the Company and their
families, provided, however, that if the Executive becomes reemployed with
another employer and is eligible to receive medical or other welfare benefits
under another employer-provided plan, the medical and other welfare benefits
described herein shall be secondary to those provided under such other plan
during such applicable period of eligibility, and for purposes of determining
eligibility (but not the time of commencement of benefits) of the Executive for
retiree benefits pursuant to such plans, practices, programs and policies, the
Executive shall be considered to have remained employed until one year after the
Date of Termination and to have retired on the last day of such period;


     (iii)  to the extent not previously paid or provided, the Company shall
timely pay or provide to the Executive any other amounts or benefits required to
be paid or provided or which the

                                      -17-
<PAGE>
 
Executive is eligible to receive under any plan, program, policy or practice or
contract or agreement of the Company (such other amounts and benefits shall be
hereinafter referred to as the "Other Benefits").


     (b)  Death.  If the Executive's employment is terminated by reason of the 
          -----
Executive's death during the Employment Period, this Agreement shall terminate
without further obligations to the Executive's legal representatives under this
Agreement, other than for payment by the Company of (i) Accrued Obligations,
(ii) Other Benefits, and (iii) an amount, in cash, equal to one times the
Executive's Annual Base Salary at the time of death. The amounts due under
clauses (i) and (iii) of the preceding sentence shall be paid to the Executive's
estate or beneficiary, as applicable, in a lump sum in cash within 30 days of
the Date of Termination.


     (c)  Disability.  If the Executive's employment is terminated by reason of 
          ----------
the Executive's Disability during the Employment Period, this Agreement shall
terminate without further obligations to the Executive, other than for payment
by the Company of (i) Accrued Obligations, (ii) Other Benefits, and (iii) an
amount, in cash, equal to one times the Executive's Annual Base Salary at the
time of termination. The amounts due under clauses (i) and (iii) of the
preceding sentence shall be paid to the Executive in a lump sum in cash within
30 days of the Date of Termination.

                                      -18-
<PAGE>
 
     (d)  Cause; Other than for Good Reason.  If the Executive's employment 
          ---------------------------------
shall be terminated for Cause during the Employment Period, this Agreement shall
terminate without further obligations to the Executive other than the obligation
to pay to the Executive (x) the Annual Base Salary through the Date of
Termination, (y) the amount of any compensation previously deferred by the
Executive, and (z) Other Benefits, in each case to the extent previously unpaid.
If the Executive voluntarily terminates employment during the Employment Period,
excluding a termination for Good Reason, this Agreement shall terminate without
further obligation to the Executive, other than for the payment by the Company
of (i) Accrued Obligations (ii) Other Benefits, and (iii) an amount, in cash,
equal to one times his Annual Base Salary at the time of termination. In such
case, all amounts due under clauses (i) and (iii) of the preceding sentence
shall be paid to the Executive in a lump sum in cash within 30 days of the Date
of Termination.


     7.   Non-exclusivity of Rights.  Nothing in this Agreement shall prevent 
          -------------------------
or limit the Executive's continuing or future participation in any plan,
program, policy or practice provided by the Company or any of its affiliated
companies and for which the Executive may qualify, nor, subject to Section
11(f), shall anything herein limit or otherwise affect such rights as the
Executive may have under any contract or agreement with the

                                      -19-
<PAGE>
 
Company or any of its affiliated companies. Amounts which are vested benefits or
which the Executive is otherwise entitled to receive under any plan, policy,
practice or program of or any contrast or agreement with the Company or any of
its affiliated companies at or subsequent to the Date of Termination shall be
payable in accordance with such plan, policy, practice or program or Contract or
agreement except as explicitly modified by this Agreement.


     8.   Full Settlement; Legal Fees.  The Company's obligation to make the 
          ---------------------------
payments provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any set-off, counterclaim, recoupment,
defense or other claim, right or action which the Company may have against the
Executive or others. In no event shall the Executive be obligated to seek other
employment or take any other action by way of mitigation of the amounts payable
to the Executive under any of the provisions of this Agreement and except as
specifically provided in Section 6(a)(ii), such amounts shall not be reduced
whether or not the Executive obtains other employment. The Company agrees to pay
as incurred, to the full extent permitted by law, all legal fees and expenses
which the Executive may reasonably incur, up to a maximum of $10,000, as a
result of any contest (regardless of the outcome thereof) by the Company, the
Executive or others of the validity or enforceability of, or liability under,
any provision

                                      -20-
<PAGE>
 
of this Agreement or any guarantee of performance thereof (including as a result
of any contest by the Executive about the amount of any payment pursuant to this
Agreement), plus in each case interest on any delayed payment at the applicable
Federal rate provided for in Section 7872(f)(2)(A) of the Internal Revenue Code
of 1986, as amended (the "Code").


     9.   Certain Additional Payments by the Company.  Payments under this 
          ------------------------------------------
Agreement shall be made without regard to whether the deductibility of such
payments (or any other payments) to or for the benefit of the Executive) would
be limited or precluded by Section 280G of the Internal Revenue Code of 1986, as
amended (the "Code") and without regard to whether such payments (or any other
payments) would subject the Executive to the federal excise tax levied on
certain "excise parachute payments" under Section 4999 of the Code; provided,
that if the total of all payments to or for the benefit of the Executive, after
reduction of all federal taxes (including the tax set forth in Section 4999 of
the Code, if applicable) with respect to such payments (the "Executive's total
after-tax payments"), would be increased by the limitation of elimination of any
payment under this Agreement, amounts payable under this Agreement shall be
reduced to the extent, and only to the extent, necessary to maximize the
Executive's total after-tax payments. The determination as to whether and to
what extent payments under this Agreement are required to be reduced in

                                      -21-
<PAGE>
 
accordance with the preceding sentence shall be made by agreement between the
Executive and the independent public accounting firm of the Company. To the
extent that any elimination or reduction of payments is made in accordance with
this Section 9, the determination as to which payments shall be eliminated or
reduced shall be made by the Executive.


     10.  Successors.  (a) This Agreement is personal to the Executive and 
          ----------
without the prior written consent of the Company shall not be assignable by the
Executive otherwise than by will or the laws of descent and distribution. This
Agreement shall inure to the benefit of and be enforceable by the Executive's
legal representatives.


     (b)  This Agreement shall inure to the benefit of and be binding upon the
Company and its successors and assigns.


     (c)  The Company will require any successor (whether direct or indirect, by
purchase, merger, consolidation or otherwise) to all or substantially all of the
business and/or assets of the Company to assume expressly and agree to perform
this Agreement in the same manner and to the same extent that the Company would
be required to perform it if no such succession had taken place. As used in this
Agreement, "Company" shall mean the Company as hereinbefore defined and any
successor to its business and/or

                                      -22-
<PAGE>
 
assets as aforesaid which assumes and agrees to perform this Agreement by
operation of law, or otherwise.


     11.  Miscellaneous.  (a) This Agreement shall be governed by and construed 
          -------------
in accordance with the laws of the State of Delaware, without reference to
principles of conflict of laws. The captions of this Agreement are not part of
the provisions hereof and shall have no force or effect. This Agreement may not
be amended or modified otherwise than by a written agreement executed by the
parties hereto or their respective successors and legal representatives.

                             EMPLOYMENT AGREEMENT
                             --------------------

     AGREEMENT by and between Calgene, Inc., a Delaware corporation (the
"Company") and Roderick N. Stacey (the "Executive"), dated as of the 19th day of
July, 1995.


     The Board of Directors of the Company (the "Board"), has determined that it
is in the best interests of the Company and its shareholders to assure that the
Company will have the continued dedication of the Executive, notwithstanding the
possibility, threat or occurrence of a Change of Control (as defined below) of
the Company. The Board believes it is imperative to diminish the inevitable
distraction of the Executive by virtue of the personal uncertainties and risks
created by a pending or threatened Change of Control and to encourage the
Executive's full attention and dedication to the Company currently and in the
event of any threatened or pending Change of Control, and to provide the
Executive with compensation and benefits arrangements upon a Change of Control
which ensure that the compensation and benefits expectations of the Executive
will be satisfied and which are competitive with those of other corporations.
Therefore, in order to accomplish these objectives, the Board has caused the
Company to enter into this Agreement
<PAGE>
 
     NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:


     l.   Certain Definitions.  (a) The "Effective Date" shall mean the first 
          -------------------
date during the Change of Control Period (as defined in Section 1(b)) on which a
Change of Control (as defined in Section 2) occurs. Anything in this Agreement
to the contrary notwithstanding, if a Change of Control occurs and if the
Executive's employment with the Company is terminated prior to the date on which
the Change of Control occurs, and if it is reasonably demonstrated by the
Executive that such termination of employment (i) was at the request of a third
party who has taken steps reasonably calculated to effect a Change of Control or
(ii) otherwise arose in connection with or anticipation of a Change of Control,
then for all purposes of this Agreement the "Effective Date" shall mean the date
immediately prior to the date of such termination of employment.


     (b)  The "Change of Control Period" shall mean the period commencing on the
date hereof and ending on the third anniversary of the date hereof; provided,
however, that commencing on the date one year after the date hereof, and on each
annual anniversary of such date (such date and each annual anniversary thereof
shall be hereinafter referred to as the "Renewal Date"), unless previously
terminated, the Change of Control Period shall be automatically extended so as
to terminate three years from such Renewal Date,

                                      -2-
<PAGE>
 
unless at least 60 days prior to the Renewal Date the Company shall give notice
to the Executive that the Change of Control Period shall not be so extended.


     2.   Change of Control.  For the purpose of this Agreement, a "Change of 
          -----------------
Control" shall mean:


     (a)  The acquisition by any individual, entity or group (within the meaning
of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act")) (a "Person") of beneficial ownership (within the
meaning of Rule 13d-3 promulgated under the Exchange Act) of 40% or more of
either (i) the then outstanding shares of common stock of the Company (the
"Outstanding Company Common Stock") or (ii) the combined voting power of the
then outstanding voting securities of the Company entitled to vote generally in
the election of directors (the "Outstanding Company Voting Securities");
provided, however, that for purposes of this subsection (a), the following
acquisitions shall not constitute a Change of Control: (i) any acquisition by
any employee benefit plan (or related trust) sponsored or maintained by the
Company or any corporation controlled by the Company or (ii) any acquisition by
any corporation pursuant to a transaction which complies with clauses (i), (ii)
and (iii) of subsection (c) of this Section 2; or

                                      -3-
<PAGE>
 
     (b)  Individuals who, as of the date hereof, constitute the Board (the
"Incumbent Board") cease for any reason to constitute at least a majority of the
Board; provided, however, that any individual becoming a director subsequent to
the date hereof whose election, or nomination for election by the Company's
shareholders, was approved by a vote of at least a majority of the directors
then comprising the Incumbent Board shall be considered as though such
individual were a member of the Incumbent Board, but excluding, for this
purpose, any such individual whose initial assumption of office occurs as a
result of an actual or threatened election contest with respect to the election
or removal or directors or other actual or threatened solicitation of proxies or
consents by or on behalf of a Person other than the Board; or


     (c)  Approval by the shareholders of the Company of a reorganization,
merger or consolidation or sale or other disposition of all or substantially all
of the assets of the Company (a "Business Combination"), in each case, unless,
immediately following such Business Combination, (i) all or substantially all of
the individuals and entities who were the beneficial owners, respectively, of
the Outstanding Company Common Stock and Outstanding Company Voting Securities
immediately prior to such Business Combination beneficially own, directly or
indirectly, more than 60% of, respectively, the then outstanding shares of
common stock and the combined voting power of the then

                                      -4-
<PAGE>
 
outstanding voting securities entitled to vote generally in the election of
directors, as the case may be, of the corporation resulting from such Business
Combination (including, without limitation, a corporation which as a result of
such transaction owns the Company or all or substantially all of the Company's
assets either directly or through one or more subsidiaries) in substantially the
same proportions as their ownership, immediately prior to such Business
Combination of the Outstanding Company Common Stock and Outstanding Company
Voting Securities, as the case may be, (ii) no Person (excluding any employee
benefit plan (or related trust) of the Company or such corporation resulting
from such Business Combination) beneficially owns, directly or indirectly, 40%
or more of, respectively, the then outstanding shares of common stock of the
corporation resulting from such Business Combination or the combined voting
power of the then outstanding voting securities of such corporation except to
the extent that such ownership existed prior to the Business Combination and
(iii) at least a majority of the members of the board of directors of the
corporation resulting from such Business Combination were members of the
Incumbent Board at the time of the execution of the initial agreement, or of the
action of the Board, providing for such Business Combination;


     (d)  Approval by the shareholders of the Company of a complete liquidation
or dissolution of the Company; or

     (e)  The closing of the transactions contemplated by the Letter of Intent
dated June 27, 1995 between the Company and Monsanto Company (the "Monsanto
Letter of Intent").


     3.   Employment Period.  The Company hereby agrees to continue the 
          -----------------
Executive in its employ, and the Executive hereby agrees to remain in the employ
of the Company subject to the terms and conditions of this Agreement, for the
period commencing on the Effective Date and ending on the third anniversary of
such date (the "Employment Period").


     4.   Terms of Employment.  (a)  Position and Duties.  (i)  During the 
          -------------------        -------------------
Employment Period, (A) the Executive's position (including status, offices,
titles and reporting requirements), authority, duties and responsibilities shall
be at least commensurate in all material respects with the most significant of
those held, exercised and assigned to the Executive at any time during the 120-
day period immediately preceding the Effective Date, except as otherwise
contemplated by the Monsanto Letter of Intent, and (B) the Executive's services
shall be performed at the location where the Executive was employed immediately
preceding the Effective Date or any office or location less than 50 miles from
such location.

                                      -6-
<PAGE>
 
     (ii)  During the Employment Period, and excluding any periods of vacation
and sick leave to which the Executive is entitled, the Executive agrees to
devote reasonable attention and time during normal business hours to the
business and affairs of the Company and, to the extent necessary to discharge
the responsibilities assigned to the Executive hereunder, to use the Executive's
reasonable efforts to perform faithfully and efficiently such responsibilities.
During the Employment Period it shall not be a violation of this Agreement for
the Executive to (A) serve on corporate, civic or charitable boards or
committees, or (B) deliver lectures and fulfill speaking engagements, so long as
such activities do not significantly interfere with the Executive's
responsibilities under this Agreement. It is expressly understood and agreed
that to the extent that any such activities have been conducted by the Executive
prior to the Effective Date, the continued conduct of such activities (or the
conduct of activities similar in nature and scope thereto) subsequent to the
Effective Date shall not thereafter be deemed to interfere with the performance
of the Executive's responsibilities to the Company.


     (b)  Compensation.   (i)  Base Salary.  During the Employment Period, the 
          ------------         -----------
Executive shall receive an annual base salary ("Annual Base Salary"), which
shall be paid at a monthly rate, at least equal to twelve times the highest
monthly base salary paid or payable, including any base salary which has been
earned but

                                      -7-
<PAGE>
 
deferred, to the Executive by the Company and its affiliated companies in
respect of the twelve-month period immediately preceding the month in which the
Effective Date occurs. During the Employment Period, the Annual Base Salary
shall be reviewed no more than 12 months after the last salary increase awarded
to the Executive prior to the Effective Date and thereafter at least annually.
Any increase in Annual Base Salary shall not serve to limit or reduce any other
obligation to the Executive under this Agreement. Annual Base Salary shall not
be reduced after any such increase and the term Annual Base Salary as utilized
in this Agreement shall refer to Annual Base Salary as so increased. As used in
this Agreement, the term "affiliated companies" shall mean any direct or
indirect subsidiary of the Company.


     (ii)  Annual Bonus.  In addition to Annual Base Salary, the Executive 
           ------------
shall be awarded, for each fiscal year ending during the Employment Period, an
annual bonus (the "Annual Bonus") in cash at least equal to the average bonus
paid to the Executive for the last three full fiscal years prior to the
Effective Date (the "Recent Average Bonus"). Each such Annual Bonus shall be
paid no later than the end of the third month of the fiscal year next following
the fiscal year for which the Annual Bonus is awarded, unless the Executive
shall elect to defer the receipt of such Annual Bonus.

                                      -8-
<PAGE>
 
     (iii)  Savings and Retirement Plans.  During the Employment Period, the 
            ----------------------------
Executive shall be entitled to participate in all savings and retirement plans,
practices, policies and programs applicable generally to other senior executives
of the Company, but in no event shall such plans, practices, policies and
programs provide the Executive with savings opportunities and retirement benefit
opportunities, in each case, less favorable, in the aggregate, than the most
favorable of those provided by the Company for the Executive under such plans,
practices, policies and programs as in effect at any time during the 120-day
period immediately preceding the Effective Date or if more favorable to the
Executive, those provided generally at any time after the Effective Date to
other senior executives of the Company.


     (iv)  Welfare Benefit Plans.  During the Employment Period, the Executive 
           ---------------------
and/or the Executive's family, as the case may be, shall be eligible for
participation in and shall receive all benefits under welfare benefit plans,
practices, policies and programs provided by the Company (including, without
limitation, medical, prescription, dental, disability, salary continuance,
employee life, group life, accidental death and travel accident insurance plans
and programs) to the extent applicable generally to other senior executives of
the Company, but in no event shall such plans, practices, policies and programs
provide the Executive with benefits which are less favorable, in the aggregate,
than the

                                      -9-
<PAGE>
 
most favorable of such plans, practices, policies and programs in effect for the
Executive at any time during the 120-day period immediately preceding the
Effective Date or, if more favorable to the Executive, those provided generally
at any time after the Effective Date to other senior executives of the Company.


     (v)  Expenses.  During the Employment Period, the Executive shall be 
          --------
entitled to receive prompt reimbursement for all reasonable expenses incurred by
the Executive in accordance with the policies, practices and procedures of the
Company in effect for the Executive at any time during the 120-day period
immediately preceding the Effective Date.


     (vi)  Vacation.  During the Employment Period, the Executive shall be 
           --------
entitled to paid vacation in accordance with the most favorable plans, policies,
programs and practices of the Company as in effect for the Executive at any time
during the 120-day period immediately preceding the Effective Date or, if more
favorable to the Executive, as in effect generally at any time thereafter with
respect to other senior executives of the Company.


     5.   Termination of Employment.  
          -------------------------


          (a)  Death or Disability.  The Executive's employment shall terminate 
               -------------------
automatically upon the Executive's death during

                                      -10-
<PAGE>
 
the Employment Period. If the Company determines in good faith that the
Disability of the Executive has occurred during the Employment Period (pursuant
to the definition of Disability set forth below), it may give to the Executive
written notice in accordance with Section 11(b) of this Agreement of its
intention to terminate the Executive's employment. In such event, the
Executive's employment with the Company shall terminate effective on the 30th
day after receipt of such notice by the Executive (the "Disability Effective
Date"), provided that, within the 30 days after such receipt, the Executive
shall not have returned to full-time performance of the Executive's duties. For
purposes of this Agreement, "Disability" shall mean the absence of the Executive
from the Executive's duties with the Company on a full-time basis for 180
consecutive business days as a result of incapacity due to mental or physical
illness which is determined to be total and permanent by a physician selected by
the Company or its insurers and acceptable to the Executive or the Executive's
legal representative.


     (b)  Cause.  The Company may terminate the Executive's employment during 
          -----
the Employment Period for Cause. For purposes of this Agreement, "Cause" shall
mean the willful engaging by the Executive in illegal conduct or gross
misconduct which is materially and demonstrably injurious to the Company. The
cessation of employment of the Executive shall not be deemed to be

                                      -11-
<PAGE>
 
for Cause unless and until there shall have been delivered to the Executive a
copy of a resolution duly adopted by the affirmative vote of not less than 
three-quarters of the entire membership of the Board at a meeting of the Board
called and held for such purpose (after reasonable notice is provided to the
Executive and the Executive is given an opportunity, together with counsel, to
be heard before the Board), finding that, in the good faith opinion of the
Board, the Executive is guilty of an act or omission constituting Cause.


     (c)  Good Reason.  The Executive's employment may be terminated by the 
          -----------
Executive for Good Reason. For purposes of this Agreement, "Good Reason" shall
mean:


          (i)  the assignment to the Executive of any duties inconsistent in any
     respect with the Executive's position (including status, offices, titles
     and reporting requirements), authority, duties or responsibilities as
     contemplated by Section 4(a) of this Agreement, except as contemplated by
     the Monsanto Letter of Intent, or any other action by the Company which
     results in a diminution in such position, authority, duties or
     responsibilities, excluding for this purpose an isolated, insubstantial and
     inadvertent action not taken in bad faith and which is remedied by the

                                      -12-
<PAGE>
 
     Company promptly after receipt of notice thereof given by the Executive;


          (ii)  any failure by the Company to comply with any of the provisions
     of Section 4(b) of this Agreement, other than an isolated, insubstantial
     and inadvertent failure not occurring in bad faith and which is remedied by
     the Company promptly after receipt of notice thereof given by the
     Executive;


          (iii)  the Company's requiring the Executive to be based at any office
     or location other than as provided in Section 4(a)(i)(B) hereof or the
     Company's requiring the Executive to travel on Company business to a
     substantially greater extent than required immediately prior to the
     Effective Date;


          (iv)  any purported termination by the Company of the Executive's
     employment otherwise than as expressly permitted by this Agreement; or


          (v)  any failure by the Company to comply with and satisfy Section
     10(c) of this Agreement.

                                      -13-
<PAGE>
 
For purposes of this Section 5(c), any good faith determination of "Good Reason"
made by the Executive shall be conclusive.


     (d)  Notice of Termination.  Any termination by the Company for Cause, or 
          ---------------------
by the Executive for Good Reason, shall be communicated by Notice of Termination
to the other party hereto given in accordance with Section 11(b) of this
Agreement. For purposes of this Agreement, a "Notice of Termination" means a
written notice which (i) indicates the specific termination provision in this
Agreement relied upon, (ii) to the extent applicable, sets forth in reasonable
detail the facts and circumstances claimed to provide a basis for termination of
the Executive's employment under the provision so indicated and (iii) if the
Date of Termination (as defined below) is other than the date of receipt of such
notice, specifies the termination date (which date shall be not more than thirty
days after the giving of such notice). The failure by the Executive or the
Company to set forth in the Notice of Termination any fact or circumstance which
contributes to a showing of Good Reason or Cause shall not waive any right of
the Executive or the Company, respectively, hereunder or preclude the Executive
or the Company, respectively, from asserting such fact or circumstance in
enforcing the Executive's or the Company's rights hereunder.

                                      -14-
<PAGE>
 
          (e)  Date of Termination.  "Date of Termination" means (i) if the 
               -------------------
Executive's employment is terminated by the Company for Cause, or by the
Executive for Good Reason, the date of receipt of the Notice of Termination or
any later date specified therein, as the case may be, (ii) if the Executive's
employment is terminated by the Company other than for Cause or Disability, the
date on which the Company notifies the Executive of such termination and (iii)
if the Executive's employment is terminated by reason of death or Disability,
the date of death of the Executive or the Disability Effective Date, as the case
may be.


          6.   Obligations of the Company upon Termination.
               -------------------------------------------


               (a)  Good Reason; Other than for Cause, Death or Disability.  If,
                    ------------------------------------------------------
during the Employment Period, the Company shall terminate the Executive's
employment other than for Cause or Disability, or the Executive shall terminate
employment for Good Reason:


     (i)  The Company shall pay to the Executive in a lump sum in cash within 30
days after the Date of Termination the aggregate of the following amounts:

     Date of Termination to the extent not previously paid, (2) the product of
     (x) the Recent Average Bonus and (y) a fraction, the numerator of which is
     the number of days in the current fiscal year through the Date of
     Termination, and the denominator of which is 365 and (3) any compensation
     previously deferred by the Executive (together with any accrued interest or
     earnings thereon) and any accrued vacation pay, in each case to the extent
     not previously paid (the sum of the amounts described in clauses (1), (2),
     and (3) shall be hereinafter referred to as the "Accrued Obligations"); and


          B.   the amount equal to the product of (1) three and (2) the sum of
     (x) the Executive's Annual Base Salary and (y) the Recent Average Bonus.


     (ii)  For one year after the Executive's Date of Termination, or such
longer period as may be provided by the terms of the appropriate plan, program,
practice or policy, the Company shall continue benefits to the Executive and/or
the Executive's family at least equal to those which would have been provided to
them in accordance with the plans, programs, practices and policies described in
Section 4(b)(iv) of this Agreement if the Executive's employment had not been
terminated or, if more favorable to the

                                      -16-
<PAGE>
 
Executive, as in effect generally at any time thereafter with respect to other
senior executives of the Company and their families, provided, however, that if
the Executive becomes reemployed with another employer and is eligible to
receive medical or other welfare benefits under another employer-provided plan,
the medical and other welfare benefits described herein shall be secondary to
those provided under such other plan during such applicable period of
eligibility, and for purposes of determining eligibility (but not the time of
commencement of benefits) of the Executive for retiree benefits pursuant to such
plans, practices, programs and policies, the Executive shall be considered to
have remained employed until one year after the Date of Termination and to have
retired on the last day of such period;


     (iii)  to the extent not previously paid or provided, the Company shall
timely pay or provide to the Executive any other amounts or benefits required to
be paid or provided or which the Executive is eligible to receive under any

other amounts and benefits shall be hereinafter referred to as the "Other
Benefits").


     (b)  Death.  If the Executive's employment is terminated by reason of the
          -----
Executive's death during the Employment Period, this Agreement shall terminate
without further obligations to the

<PAGE>
 
Executive's legal representatives under this Agreement, other than for payment

amount, in cash, equal to one times the Executive's Annual Base Salary at the
time of termination. The amounts due under clauses (i) and (iii) of the
preceding sentence shall be paid to the Executive in a lump sum in cash within
30 days of the Date of Termination.


     (d)  Cause.  If the Executive's employment shall be terminated for Cause 
          -----
during the Employment Period, this Agreement shall terminate without further
obligations to the Executive other than the obligation to pay to the Executive
(x) the Annual Base Salary through the Date of Termination, (y) the amount of
any compensation previously deferred by the Executive, and (z) Other Benefits,
in each case to the extent previously unpaid.

                                      -18-
<PAGE>
 
     (e)  Other than For Good Reason.  If the Executive voluntarily terminates 
          --------------------------
employment during the Employment Period, excluding a termination for Good Reason
or pursuant to Section 6(f), this Agreement shall terminate without further
obligation to the Executive, other than for the payment by the Company of (i)
Accrued Obligations (ii) Other Benefits, and (iii) an amount, in cash, equal to
one times his Annual Base Salary at the time of termination. In such case, all
amounts due under clauses (i) and (iii) of the preceding sentence shall be paid
to the Executive in a lump sum in cash within 30 days of the Date of
Termination.


     (f)  End of Term.  If the Executive voluntarily provides notice of 
          -----------
termination of his employment during the 90-day period immediately prior to the
expiration of the Employment Period, effective as of the end of the Employment
Period, the Company shall pay to the Executive (i) Accrued Obligations, (ii)
Other Benefits and (iii) an amount, in cash, equal to two times his Annual Base
Salary at the time of termination. In such case, all amounts due under clauses

sum in cash within 30 days of the Date of Termination.


     7.   Non-exclusivity of Rights.  Nothing in this Agreement shall prevent

or limit the Executive's continuing or future

                                      -19-
<PAGE>
 
participation in any plan, program, policy or practice provided by the Company
or any of its affiliated companies and for which the Executive may qualify, nor,
subject to Section 11(f), shall anything herein limit or otherwise affect such
rights as the Executive may have under any contract or agreement with the
Company or any of its affiliated companies. Amounts which are vested benefits or
which the Executive is otherwise entitled to receive under any plan, policy,
practice or program of or any contrast or agreement with the Company or any of
its affiliated companies at or subsequent to the Date of Termination shall be
payable in accordance with such plan, policy, practice or program or Contract or
agreement except as explicitly modified by this Agreement.


     8.   Full Settlement; Legal Fees.  The Company's obligation to make the 
          ---------------------------
payments provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any set-off, counterclaim, recoupment,
defense or other claim, right or action which the Company may have against the
Executive or others. In no event shall the Executive be obligated to seek other
employment or take any other action by way of mitigation of the amounts payable
to the Executive under any of the provisions of this Agreement and except as
specifically provided in Section 6(a)(ii), such amounts shall not be reduced
whether or not the Executive obtains other employment. The Company agrees to pay

                                      -20-
<PAGE>
 
as incurred, to the full extent permitted by law, all legal fees and expenses
which the Executive may reasonably incur, up to a maximum of $10,000, as a
result of any contest (regardless of the outcome thereof) by the Company, the
Executive or others of the validity or enforceability of, or liability under,
any provision of this Agreement or any guarantee of performance thereof
(including as a result of any contest by the Executive about the amount of any
payment pursuant to this Agreement), plus in each case interest on any delayed
payment at the applicable Federal rate provided for in Section 7872(f)(2)(A) of
the Internal Revenue Code of 1986, as amended (the "Code").


     9.   Certain Additional Payments by the Company.  Payments under this 
          ------------------------------------------
Agreement shall be made without regard to whether the deductibility of such
payments (or any other payments) to or for the benefit of the Executive) would
be limited or precluded by Section 280G of the Internal Revenue Code of 1986, as
amended (the "Code") and without regard to whether such payments (or any other
payments) would subject the Executive to the federal excise tax levied on
certain "excise parachute payments" under Section 4999 of the Code; provided,
that if the total of all payments to or for the benefit of the Executive, after
reduction of all federal taxes (including the tax set forth in Section 4999 of
the Code, if applicable) with respect to such payments (the "Executive's total
after-tax payments"), would be increased by the limitation of

                                      -21-
<PAGE>
 
elimination of any payment under this Agreement, amounts payable under this
Agreement shall be reduced to the extent, and only to the extent, necessary to
maximize the Executive's total after-tax payments. The determination as to

                               CHANGE OF CONTROL
                             EMPLOYMENT AGREEMENT
                             --------------------


     AGREEMENT by and between Calgene, Inc., a Delaware corporation (the
"Company") and Michael J. Motroni (the "Executive"), dated as of the 19th day of
July, 1995.


     The Board of Directors of the Company (the "Board"), has determined that it
is in the best interests of the Company and its shareholders to assure that the
Company will have the continued dedication of the Executive, notwithstanding the
possibility, threat or occurrence of a Change of Control (as defined below) of
the Company. The Board believes it is imperative to diminish the inevitable
distraction of the Executive by virtue of the personal uncertainties and risks
created by a pending or threatened Change of Control and to encourage the
Executive's full attention and dedication to the Company currently and in the
event of any threatened or pending Change of Control, and to provide the
Executive with compensation and benefits arrangements upon a Change of Control
which ensure that the compensation and benefits expectations of the Executive
will be satisfied and which are competitive with those of other corporations.
Therefore, in order to accomplish these objectives, the Board has caused the
Company to enter into this Agreement
<PAGE>
 
     NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:


     l.   Certain Definitions.  (a) The "Effective Date" shall mean the first 
          -------------------
date during the Change of Control Period (as defined in Section 1(b)) on which a
Change of Control (as defined in Section 2) occurs. Anything in this Agreement
to the contrary notwithstanding, if a Change of Control occurs and if the
Executive's employment with the Company is terminated prior to the date on which
the Change of Control occurs, and if it is reasonably demonstrated by the
Executive that such termination of employment (i) was at the request of a third
party who has taken steps reasonably calculated to effect a Change of Control or
(ii) otherwise arose in connection with or anticipation of a Change of Control,
then for all purposes of this Agreement the "Effective Date" shall mean the date
immediately prior to the date of such termination of employment.


     (b)  The "Change of Control Period" shall mean the period commencing on the
date hereof and ending on the third anniversary of the date hereof; provided,
however, that commencing on the date one year after the date hereof, and on each
annual anniversary of such date (such date and each annual anniversary thereof
shall be hereinafter referred to as the "Renewal Date"), unless previously
terminated, the Change of Control Period shall be automatically extended so as
to terminate three years from such Renewal Date,

                                      -2-
<PAGE>
 
unless at least 60 days prior to the Renewal Date the Company shall give notice
to the Executive that the Change of Control Period shall not be so extended.


     2.   Change of Control.  For the purpose of this Agreement, a "Change of 
          -----------------
Control" shall mean:


     (a)  The acquisition by any individual, entity or group (within the meaning
of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act")) (a "Person") of beneficial ownership (within the
meaning of Rule 13d-3 promulgated under the Exchange Act) of 40% or more of
either (i) the then outstanding shares of common stock of the Company (the
"Outstanding Company Common Stock") or (ii) the combined voting power of the
then outstanding voting securities of the Company entitled to vote generally in
the election of directors (the "Outstanding Company Voting Securities");
provided, however, that for purposes of this subsection (a), the following
acquisitions shall not constitute a Change of Control: (i) any acquisition by
any employee benefit plan (or related trust) sponsored or maintained by the
Company or any corporation controlled by the Company or (ii) any acquisition by
any corporation pursuant to a transaction which complies with clauses (i), (ii)
and (iii) of subsection (c) of this Section 2; or

                                      -3-
<PAGE>
 
     (b)  Individuals who, as of the date hereof, constitute the Board (the
"Incumbent Board") cease for any reason to constitute at least a majority of the
Board; provided, however, that any individual becoming a director subsequent to
the date hereof whose election, or nomination for election by the Company's
shareholders, was approved by a vote of at least a majority of the directors
then comprising the Incumbent Board shall be considered as though such
individual were a member of the Incumbent Board, but excluding, for this
purpose, any such individual whose initial assumption of office occurs as a
result of an actual or threatened election contest with respect to the election
or removal or directors or other actual or threatened solicitation of proxies or
consents by or on behalf of a Person other than the Board; or


     (c)  Approval by the shareholders of the Company of a reorganization,
merger or consolidation or sale or other disposition of all or substantially all
of the assets of the Company (a "Business Combination"), in each case, unless,
immediately following such Business Combination, (i) all or substantially all of
the individuals and entities who were the beneficial owners, respectively, of
the Outstanding Company Common Stock and Outstanding Company Voting Securities
immediately prior to such Business Combination beneficially own, directly or
indirectly, more than 60% of, respectively, the then outstanding shares of
common stock and the combined voting power of the then

                                      -4-
<PAGE>
 
outstanding voting securities entitled to vote generally in the election of
directors, as the case may be, of the corporation resulting from such Business
Combination (including, without limitation, a corporation which as a result of
such transaction owns the Company or all or substantially all of the Company's
assets either directly or through one or more subsidiaries) in substantially the
same proportions as their ownership, immediately prior to such Business
Combination of the Outstanding Company Common Stock and Outstanding Company
Voting Securities, as the case may be, (ii) no Person (excluding any employee
benefit plan (or related trust) of the Company or such corporation resulting
from such Business Combination) beneficially owns, directly or indirectly, 40%
or more of, respectively, the then outstanding shares of common stock of the
corporation resulting from such Business Combination or the combined voting
power of the then outstanding voting securities of such corporation except to
the extent that such ownership existed prior to the Business Combination and
(iii) at least a majority of the members of the board of directors of the
corporation resulting from such Business Combination were members of the
Incumbent Board at the time of the execution of the initial agreement, or of the
action of the Board, providing for such Business Combination;


     (d)  Approval by the shareholders of the Company of a complete liquidation
or dissolution of the Company; or

                                      -5-

     (e)  The closing of the transactions contemplated by the Letter of Intent
dated June 27, 1995 between the Company and Monsanto Company (the "Monsanto
Letter of Intent").


     3.   Employment Period.  The Company hereby agrees to continue the 
          -----------------
Executive in its employ, and the Executive hereby agrees to remain in the employ
of the Company subject to the terms and conditions of this Agreement, for the
period commencing on the Effective Date and ending on the third anniversary of
such date (the "Employment Period")


     4.   Terms of Employment.  (a) Position and Duties. (i) During the 
          -------------------       -------------------
Employment Period, (A) the Executive's position (including status, offices,
titles and reporting requirements), authority, duties and responsibilities shall
be at least commensurate in all material respects with the most significant of
those held, exercised and assigned to the Executive at any time during the 120-
day period immediately preceding the Effective Date, except as otherwise
contemplated by the Monsanto Letter of Intent, and (B) the Executive's services
shall be performed at the location where the Executive was employed immediately
preceding the Effective Date or any office or location less than 50 miles from
such location.

                                      -6-
<PAGE>
 
     (ii)  During the Employment Period, and excluding any periods of vacation
and sick leave to which the Executive is entitled, the Executive agrees to
devote reasonable attention and time during normal business hours to the
business and affairs of the Company and, to the extent necessary to discharge
the responsibilities assigned to the Executive hereunder, to use the Executive's
reasonable efforts to perform faithfully and efficiently such responsibilities.
During the Employment Period it shall not be a violation of this Agreement for
the Executive to (A) serve on corporate, civic or charitable boards or
committees, or (B) deliver lectures and fulfill speaking engagements, so long as
such activities do not significantly interfere with the Executive's
responsibilities under this Agreement. It is expressly understood and agreed
that to the extent that any such activities have been conducted by the Executive
prior to the Effective Date, the continued conduct of such activities (or the
conduct of activities similar in nature and scope thereto) subsequent to the
Effective Date shall not thereafter be deemed to interfere with the performance
of the Executive's responsibilities to the Company.


     (b)  Compensation.   (i)  Base Salary.  During the Employment Period, the 
          ------------         -----------
Executive shall receive an annual base salary ("Annual Base Salary"), which
shall be paid at a monthly rate, at least equal to twelve times the highest
monthly base salary paid or payable, including any base salary which has been
earned but

                                      -7-
<PAGE>
 
deferred, to the Executive by the Company and its affiliated companies in
respect of the twelve-month period immediately preceding the month in which the
Effective Date occurs. During the Employment Period, the Annual Base Salary
shall be reviewed no more than 12 months after the last salary increase awarded
to the Executive prior to the Effective Date and thereafter at least annually.
Any increase in Annual Base Salary shall not serve to limit or reduce any other
obligation to the Executive under this Agreement. Annual Base Salary shall not
be reduced after any such increase and the term Annual Base Salary as utilized
in this Agreement shall refer to Annual Base Salary as so increased. As used in
this Agreement, the term "affiliated companies" shall mean any direct or
indirect subsidiary of the Company.


     (ii)  Annual Bonus.  In addition to Annual Base Salary, the Executive 
           ------------
shall be awarded, for each fiscal year ending during the Employment Period, an
annual bonus (the "Annual Bonus") in cash at least equal to the average bonus
paid to the Executive for the last three full fiscal years prior to the
Effective Date (the "Recent Average Bonus"). Each such Annual Bonus shall be
paid no later than the end of the third month of the fiscal year next following
the fiscal year for which the Annual Bonus is awarded, unless the Executive
shall elect to defer the receipt of such Annual Bonus.

                                      -8-
<PAGE>
 
     (iii)  Savings and Retirement Plans.  During the Employment Period, the 
            ----------------------------
Executive shall be entitled to participate in all savings and retirement plans,
practices, policies and programs applicable generally to other senior executives
of the Company, but in no event shall such plans, practices, policies and
programs provide the Executive with savings opportunities and retirement benefit
opportunities, in each case, less favorable, in the aggregate, than the most
favorable of those provided by the Company for the Executive under such plans,
practices, policies and programs as in effect at any time during the 120-day
period immediately preceding the Effective Date or if more favorable to the
Executive, those provided generally at any time after the Effective Date to
other senior executives of the Company.


     (iv)  Welfare Benefit Plans.  During the Employment Period, the Executive 
           ---------------------
and/or the Executive's family, as the case may be, shall be eligible for
participation in and shall receive all benefits under welfare benefit plans,
practices, policies and programs provided by the Company (including, without
limitation, medical, prescription, dental, disability, salary continuance,
employee life, group life, accidental death and travel accident insurance plans
and programs) to the extent applicable generally to other senior executives of
the Company, but in no event shall such plans, practices, policies and programs
provide the Executive with benefits which are less favorable, in the aggregate,
than the

                                      -9-
<PAGE>
 
most favorable of such plans, practices, policies and programs in effect for the
Executive at any time during the 120-day period immediately preceding the
Effective Date or, if more favorable to the Executive, those provided generally
at any time after the Effective Date to other senior executives of the Company.


     (v)  Expenses.  During the Employment Period, the Executive shall be 
          --------
entitled to receive prompt reimbursement for all reasonable expenses incurred by
the Executive in accordance with the policies, practices and procedures of the
Company in effect for the Executive at any time during the 120-day period
immediately preceding the Effective Date.


     (vi)  Vacation.  During the Employment Period, the Executive shall be 
           --------
entitled to paid vacation in accordance with the most favorable plans, policies,
programs and practices of the Company as in effect for the Executive at any time
during the 120-day period immediately preceding the Effective Date or, if more
favorable to the Executive, as in effect generally at any time thereafter with
respect to other senior executives of the Company.


     5.   Termination of Employment.  
          -------------------------


          (a)  Death or Disability.  The Executive's employment shall 
               -------------------
terminate automatically upon the Executive's death during

                                      -10-
<PAGE>
 
the Employment Period. If the Company determines in good faith that the
Disability of the Executive has occurred during the Employment Period (pursuant
to the definition of Disability set forth below), it may give to the Executive
written notice in accordance with Section 11(b) of this Agreement of its
intention to terminate the Executive's employment. In such event, the
Executive's employment with the Company shall terminate effective on the 30th
day after receipt of such notice by the Executive (the "Disability Effective
Date"), provided that, within the 30 days after such receipt, the Executive
shall not have returned to full-time performance of the Executive's duties. For
purposes of this Agreement, "Disability" shall mean the absence of the Executive
from the Executive's duties with the Company on a full-time basis for 180
consecutive business days as a result of incapacity due to mental or physical
illness which is determined to be total and permanent by a physician selected by
the Company or its insurers and acceptable to the Executive or the Executive's
legal representative.


     (b)  Cause.  The Company may terminate the Executive's employment during 
          -----
the Employment Period for Cause. For purposes of this Agreement, "Cause" shall
mean the willful engaging by the Executive in illegal conduct or gross
misconduct which is materially and demonstrably injurious to the Company. The
cessation of employment of the Executive shall not be deemed to be

                                      -11-
<PAGE>
 
for Cause unless and until there shall have been delivered to the Executive a
copy of a resolution duly adopted by the affirmative vote of not less than 
three-quarters of the entire membership of the Board at a meeting of the Board
called and held for such purpose (after reasonable notice is provided to the
Executive and the Executive is given an opportunity, together with counsel, to
be heard before the Board), finding that, in the good faith opinion of the
Board, the Executive is guilty of an act or omission constituting Cause.


     (c)  Good Reason.  The Executive's employment may be terminated by the 
          -----------
Executive for Good Reason. For purposes of this Agreement, "Good Reason" shall
mean:


          (i)  the assignment to the Executive of any duties inconsistent in any
     respect with the Executive's position as Chief Financial Officer of the
     Company (including status, offices, titles and reporting requirements),
     authority, duties or responsibilities as contemplated by Section 4(a) of
     this Agreement or any other action by the Company which results in a
     diminution in such position, authority, duties or responsibilities
     (including the removal of chief financial officer responsibilities),
     excluding for this purpose an isolated, insubstantial and inadvertent
     action not taken in

                                      -12-
<PAGE>
 
     bad faith and which is remedied by the Company promptly after receipt of
     notice thereof given by the Executive;


          (ii)  any failure by the Company to comply with any of the provisions
     of Section 4(b) of this Agreement, other than an isolated, insubstantial
     and inadvertent failure not occurring in bad faith and which is remedied by
     the Company promptly after receipt of notice thereof given by the
     Executive;


          (iii)  the Company's requiring the Executive to be based at any office
     or location other than as provided in Section 4(a)(i)(B) hereof or the
     Company's requiring the Executive to travel on Company business to a
     substantially greater extent than required immediately prior to the
     Effective Date;


          (iv)  any purported termination by the Company of the Executive's
     employment otherwise than as expressly permitted by this Agreement; or


          (v)  any failure by the Company to comply with and satisfy Section
     10(c) of this Agreement.

                                      -13-
<PAGE>
 
For purposes of this Section 5(c), any good faith determination of "Good Reason"
made by the Executive shall be conclusive.


     (d)  Notice of Termination.  Any termination by the Company for Cause, or 
          ---------------------
by the Executive for Good Reason, shall be communicated by Notice of Termination
to the other party hereto given in accordance with Section 11(b) of this
Agreement. For purposes of this Agreement, a "Notice of Termination" means a
written notice which (i) indicates the specific termination provision in this
Agreement relied upon, (ii) to the extent applicable, sets forth in reasonable
detail the facts and circumstances claimed to provide a basis for termination of
the Executive's employment under the provision so indicated and (iii) if the
Date of Termination (as defined below) is other than the date of receipt of such
notice, specifies the termination date (which date shall be not more than thirty
days after the giving of such notice). The failure by the Executive or the
Company to set forth in the Notice of Termination any fact or circumstance which
contributes to a showing of Good Reason or Cause shall not waive any right of
the Executive or the Company, respectively, hereunder or preclude the Executive
or the Company, respectively, from asserting such fact or circumstance in
enforcing the Executive's or the Company's rights hereunder.

                                      -14-
<PAGE>
 
          (e)  Date of Termination.  "Date of Termination" means (i) if the 
               -------------------
Executive's employment is terminated by the Company for Cause, or by the
Executive for Good Reason, the date of receipt of the Notice of Termination or
any later date specified therein, as the case may be, (ii) if the Executive's
employment is terminated by the Company other than for Cause or Disability, the
date on which the Company notifies the Executive of such termination and (iii)
if the Executive's employment is terminated by reason of death or Disability,
the date of death of the Executive or the Disability Effective Date, as the case
may be.


          6.   Obligations of the Company upon Termination.
               -------------------------------------------


               (a)  Good Reason; Other than for Cause, Death or Disability. If,
                    ------------------------------------------------------
during the Employment Period, the Company shall terminate the Executive's
employment other than for Cause or Disability, or the Executive shall terminate
employment for Good Reason:


     (i)  The Company shall pay to the Executive in a lump sum in cash within 30
days after the Date of Termination the aggregate of the following amounts:

                                      -15-
<PAGE>
 
          A.   The sum of (l) the Executive's Annual Base Salary through the
     Date of Termination to the extent not previously paid, (2) the product of
     (x) the Recent Average Bonus and (y) a fraction, the numerator of which is
     the number of days in the current fiscal year through the Date of
     Termination, and the denominator of which is 365 and (3) any compensation
     previously deferred by the Executive (together with any accrued interest or
     earnings thereon) and any accrued vacation pay, in each case to the extent
     not previously paid (the sum of the amounts described in clauses (1), (2),
     and (3) shall be hereinafter referred to as the "Accrued Obligations"); and


          B.   the amount equal to the product of (1) three and (2) the sum of
     (x) the Executive's Annual Base Salary and (y) the Recent Average Bonus.


     (ii)  For one year after the Executive's Date of Termination, or such
longer period as may be provided by the terms of the appropriate plan, program,
practice or policy, the Company shall continue benefits to the Executive and/or
the Executive's family at least equal to those which would have been provided to
them in accordance with the plans, programs, practices and policies described in
Section 4(b)(iv) of this Agreement if the Executive's employment had not been
terminated or, if more favorable to the

                                      -16-
<PAGE>
 
Executive, as in effect generally at any time thereafter with respect to other
senior executives of the Company and their families, provided, however, that if
the Executive becomes reemployed with another employer and is eligible to
receive medical or other welfare benefits under another employer-provided plan,
the medical and other welfare benefits described herein shall be secondary to
those provided under such other plan during such applicable period of

     (e)  Other than For Good Reason.  If the Executive voluntarily terminates 
          --------------------------
employment during the Employment Period, excluding a termination for Good
Reason, this Agreement shall terminate without further obligation to the

(ii) Other Benefits, and (iii) an amount, in cash, equal to one times his Annual
Base Salary at the time of termination. In such case, all amounts due under
clauses (i) and (iii) of the preceding sentence shall be paid to the Executive

     7.   Non-exclusivity of Rights.  Nothing in this Agreement shall prevent 
          -------------------------
or limit the Executive's continuing or future participation in any plan,
program, policy or practice provided by the Company or any of its affiliated
companies and for which the Executive may qualify, nor, subject to Section
11(f), shall anything herein limit or otherwise affect such rights as the
Executive may have under any contract or agreement with the Company or any of
its affiliated companies. Amounts which are vested benefits or which the
Executive is otherwise entitled to receive under any plan, policy, practice or
program of or any contrast or agreement with the Company or any of its
affiliated companies at or subsequent to the Date of Termination shall be
payable in accordance with such plan, policy, practice or program

                                      -19-

or Contract or agreement except as explicitly modified by this Agreement.


     8.   Full Settlement; Legal Fees.  The Company's obligation to make the 
          ---------------------------
payments provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any set-off, counterclaim, recoupment,
defense or other claim, right or action which the Company may have against the
Executive or others. In no event shall the Executive be obligated to seek other
employment or take any other action by way of mitigation of the amounts payable
to the Executive under any of the provisions of this Agreement and except as
specifically provided in Section 6(a)(ii), such amounts shall not be reduced
whether or not the Executive obtains other employment. The Company agrees to pay
as incurred, to the full extent permitted by law, all legal fees and expenses
which the Executive may reasonably incur, up to a maximum of $10,000, as a
result of any contest (regardless of the outcome thereof) by the Company, the
Executive or others of the validity or enforceability of, or liability under,
any provision of this Agreement or any guarantee of performance thereof
(including as a result of any contest by the Executive about the amount of any
payment pursuant to this Agreement), plus in each case interest on any delayed
payment at the applicable Federal rate provided for in Section 7872(f)(2)(A) of
the Internal Revenue Code of 1986, as amended (the "Code").

     9.   Certain Additional Payments by the Company.  Payments under this 
          ------------------------------------------
Agreement shall be made without regard to whether the deductibility of such
payments (or any other payments) to or for the benefit of the Executive) would
be limited or precluded by Section 280G of the Internal Revenue Code of 1986, as
amended (the "Code") and without regard to whether such payments (or any other
payments) would subject the Executive to the federal excise tax levied on
certain "excise parachute payments" under Section 4999 of the Code; provided,
that if the total of all payments to or for the benefit of the Executive, after
reduction of all federal taxes (including the tax set forth in Section 4999 of
the Code, if applicable) with respect to such payments (the "Executive's total
after-tax payments"), would be increased by the limitation of elimination of any
payment under this Agreement, amounts payable under this Agreement shall be
reduced to the extent, and only to the extent, necessary to maximize the
Executive's total after-tax payments. The determination as to whether and to
what extent payments under this Agreement are required to be reduced in
accordance with the preceding sentence shall be made by agreement between the
Executive and the independent public accounting firm of the Company. To the
extent that any elimination or reduction of payments is made in accordance with
this Section 9, the determination as to which payments shall be eliminated or
reduced shall be made by the Executive.

business and/or assets of the Company to assume expressly and agree to perform
this Agreement in the same manner and to the same extent that the Company would
be required to perform it if no such succession had taken place. As used in this
Agreement, "Company" shall mean the Company as hereinbefore defined and any
successor to its business and/or assets as aforesaid which assumes and agrees to
perform this Agreement by operation of law, or otherwise.


     11.  Miscellaneous.  (a) This Agreement shall be governed by and construed 
          -------------
in accordance with the laws of the State of Delaware, without reference to
principles of conflict of laws. The captions of this Agreement are not part of

From and after the Effective Date this Agreement shall supersede any other
agreement between the parties with respect to the subject matter hereof.

"Liabilities and Investment Certificate") setting forth the amount of: (i) the 
1995-1996 Crop Liabilities which are outstanding as of the Closing Date, and 
(ii) the Investment outstanding as of the Closing Date for which Buyer is 
responsible as provided in this Section 2.5 to the extent such amount is

Seller, as required to verify and/or audit such calculations. Buyer shall have

second, to pay the Seller for the Investment. Seller agrees to use all Gross
Crop Revenues received from Buyer, first, to make payments on the portion of the
Investment related to the Operating Line, and second to reimburse Seller for the
remainder of the Investment. Seller agrees to provide Buyer with such assurances
as Buyer shall reasonably require to assure Buyer that Gross Crop Revenues are
being used by Seller to make payments on the Operating Line to reduce the
Investment. In no event shall Buyer be responsible to pay any default interest
or expenses incurred by Seller because of any default by Seller under the
Operating Line, provided that Buyer is in compliance with its obligations to
make payments to Seller under this subsection (c) and subsection (d).

               (d)  If the Gross Crop Revenues paid to Seller are not adequate 
to pay the balance owing under the Investment (other than default charges as set
forth above) by September 1, 1996, then Buyer shall pay such remaining balance 
on September 1, 1996.

          2.6  Investment Guaranty.  Buyer shall guarantee the portion of the 
               -------------------
Operating Line relating to the Investment by executing a guaranty relating 
thereto in a form reasonably satisfactory to Buyer, Seller and such lender under
the Operating Line.

          2.7  Prudential Loan Assumption.  Subject to Prudential's consent 
               --------------------------
(which Seller and Buyer will use reasonable efforts to obtain prior to the 
Closing), Buyer may (at its option and at its sole expense) assume, and agree to
pay in accordance with its terms, a portion of the Prudential Loan and related 
Prudential Loan Documents; provided, that, following such assumption, neither

                                      15


<PAGE>
 
Seller nor any of its Affiliates shall have any continuing obligation or 
encumbrance on any of their assets with respect to the Prudential Loan. If the 
Buyer so assumes a Portion of the Prudential Loan and related Prudential Loan 
Documents, then (i) the original principal amount of the Buyer Notes stated in 
Section 2.3(a)(ii)($10,000,000), beginning with the first Buyer Note, shall be 
reduced by the amount so assumed (whether for outstanding principal or accrued 
interest), and (ii) Seller shall execute a Subordination Agreement (Owned 
Properties) as provided in Section 2.4. Buyer shall pay any fees or expenses 
imposed by Prudential, and any documentary or excise taxes payable in connection
with any such assumption. Seller shall not be liable to pay any fees or expenses
in connection with such assumption.

          2.8  Allocation of Consideration. The Buyer and Seller agree that in 
               ---------------------------
order to comply with financial reporting and tax accounting requirements, it is 
necessary for them to allocate among the Assets both the amount and the types of
consideration paid or assumed by Buyer pursuant to this Agreement including the 
Closing Date Cash payment, the Buyer Notes, the Earn-Out payment and Assumed 
Liabilities. The Allocation of the Purchase Price is as set forth in 
Schedule 2.8 hereto (which the parties acknowledge is an allocation based on the
- - ------------
fair market value of the Assets determined by arm's length negotiations). Seller
and Buyer jointly shall complete and separately file Form 8594 with their
respective federal income tax returns for the tax year in which the Closing Date
occurs in accordance with such allocation. The parties shall prepare their
respective federal, state and local tax returns in a manner consistent with such
Form 8594. Neither Seller nor Buyer shall, without the written consent of the
other, take a position (i) on any tax return, (ii) before any Governmental Body
charged with the collection of any such tax, or (iii) in any judicial
proceeding, that is in any manner inconsistent with the terms of such
allocation.

          2.9  Farmland Leases.  At the Closing, the Seller shall cause the 
               ---------------
Farmland Lease Agreement to be executed and delivered to the Buyer, and Buyer 
shall execute and deliver the Farmland Lease Agreement.

          2.10 Closing.  The closing of the transactions contemplated herein 
               -------
(the "Closing") shall take place at the offices of Buyer's counsel, Karp & 
Genauer, P.A., 2 Alhambra Plaza, Suite 1202, Coral Gables, Florida 33134, at

date, time or place is agreed to by the parties hereto, but in no event shall 
the Closing Date be later than the date described in Section 8.15(iv) hereof.

date of the Current Seller Balance Sheet, which would, in the aggregate, have a

shall terminate, except with respect to information not directly related to the
Business.

          (h)  HSR. If required by applicable law, each party agrees to
               ----
cooperate in, and use its reasonable efforts to complete, any necessary filings
under the HSR Act, and any other necessary governmental filings, in respect of
the transactions contemplated hereby.

     5.2  Actions at the Closing.
          ---------------------- 

          (a)  Prorations.   All personal and real property taxes with respect 
               ----------
to the Assets to be conveyed to Buyer pursuant hereto and any charges for rents,
utilities, governmental fees and charges or other operating costs of the
Business shall be prorated through July 1, 1995. If the 1995 tax year's bills
are not issued before the Closing, then prorations for taxes shall be based on
the immediately prior year's tax bills and adjusted post-Closing after the
current tax year's tax bills are issued and received. The parties will execute a
closing statement reflecting such prorations and adjustments. If any amount is
due from either party to the other party as a result of any such proration, the
resulting amount payable shall be paid immediately upon demand in a written
notice containing reasonable evidence and calculation of such amount.

     5.3  Actions after the Closing.
          ------------------------- 

          (a)  Further Assurances.  From time to time after the Closing, Seller 
               ------------------
(for no additional consideration, but otherwise at Buyer's expense) shall
execute and deliver to Buyer such instruments of sale, transfer, conveyance,
assignment, delivery, consents, assurances, powers of attorney and other similar
instruments as may be reasonably requested by Buyer or its counsel in order to
vest in Buyer all right, title and interest in and to the Assets, and each party
shall execute and perform all documents or acts reasonably requested by another
party in order to carry out the purposes and intent of this Agreement.

          (b)  Misdirected Funds. Each party shall on and after the Closing, 
               -----------------
execute and deliver any documents and perform any acts as reasonably requested
by the other to minimize the occurrence of Misdirected Funds, including but not
limited to notices to account debtors and other third parties. Any Misdirected
Funds shall be received in trust for the benefit of the party entitled to the
same, and shall be promptly delivered to such party in the exact form received
(except for endorsement of instruments in favor of such party). As of the
Closing Date, Seller hereby authorizes Buyer to open any and all mail addressed
to Seller and delivered to the Facilities or otherwise delivered to Buyer on or
after the Closing Date. Seller hereby appoints Buyer its attorney-in-fact to
endorse, cash and deposit any monies, checks or negotiable instruments

                                       31
<PAGE>
 
received by Buyer after the Closing Date with respect to any accounts receivable
transferred by Seller to Buyer as an Asset in connection with this Agreement and
made payable or endorsed to Seller or its order, for Buyer's own account.

          (c)  Failure to obtain certain Consents.  Nothing contained in this 
               ----------------------------------
Agreement shall be construed as an attempt to agree or an agreement to assign
any Asset, including, without limitation, any Contract, agreement or license,
which is in law non-assignable or which is non-assignable without the consent of
another Person, unless such consent shall be given. The Seller shall use
reasonable efforts to obtain all necessary consents of such Persons to the
assignment of any such Assets. If the required consent of any Person to the
assignment of any Asset cannot be obtained, or if any attempted assignment of
any Asset would be ineffective or would adversely affect, as applicable, the
Seller's rights thereunder so that Buyer would not in fact receive all such
rights, the Seller, at Buyer's expense, shall cooperate in any arrangement Buyer
may reasonably request to provide for Buyer the benefit of any such Asset,
including enforcement for the benefit of Buyer of any and all of the Seller's
rights against any other party thereto arising out of the breach or cancellation
thereof by such party or otherwise.

          (d)  Access after Closing.  Each of the Seller and Buyer shall 
               --------------------
maintain or cause to be maintained, at no cost to the other party, at its
offices where such records may be kept in the ordinary course of its business,
all such books and records which relate to the Assets, the Excluded Assets
relating to the Business, the Assumed Liabilities and the Excluded Liabilities
relating to the Business, and shall afford to each other and their respective
accountants, counsel and other representatives, at the requesting party's
expense, full and complete access, upon reasonable notice and in such manner as
will not unreasonably interfere with the conduct of business, to such books and
records.

          (e)  Buyer's Books and Records.  Buyer covenants that it will 
               -------------------------- 
maintain complete and auditable separate books and records for the Combined
Business during the Earn-Out Period as defined in Exhibit B hereto (except that
                                                  ---------
for the fiscal year ended June 30, 1996, Buyer shall maintain complete and
auditable separate books and records for each of the Business and for the 
portion of the Combined Business conducted by Buyer as of the commencement of 
the Earn-Out Period, it being understood that Seller shall have maintained 
complete and auditable separate books and records for the Business from July 1, 
1995 through the Closing Date), and permit the Seller and its authorized 
representatives access thereto, subject to the confidentiality provisions of 
this Agreement.

          (f)  Confidentiality after Closing. After the Closing, (i) all
               -----------------------------
information relating to the Assets, Business and Assumed Liabilities shall be
the confidential information of Buyer and (ii) information disclosed in
connection with the exercise of access or similar rights provided herein shall
be the confidential information of the disclosing party. Each party will hold
the confidential information of the other party in the strictest confidence, and
will not without the consent of the other disclose another party's confidential
information without the prior written consent of such party, except as required
by law or in connection with the enforcement of its rights hereunder or under
any of the Transaction Documents.

                                       32
<PAGE>
 
          (g)  Restriction on Use of "Collier Farms" Name.  Even though the
               ------------------------------------------
Trademarks which are included as part of the Assets do not include the trade
name of "Collier Farms," Seller nonetheless agrees that, for a period of ten
(10) years following the Closing Date, Seller will not engage in a business
which is competitive with the Business in the United States using the name of
"Collier Farms" or any other name which includes the name "Collier."

     5.4  Title; Instruments of Conveyance and Assumption.
          ----------------------------------------------- 

          (a)  Seller has heretofore delivered to Buyer copies of all title
insurance policies or commitments (including copies of exceptions thereto),
abstracts of title, updated surveys and related documents relating to each Owned
Property in Seller's possession.  Based thereupon, Buyer shall at its expense
procure title insurance commitments committing to insure Buyer's title to the
Owned Properties in the amount shown on the Allocation of Purchase Price
attached hereto as Schedule 2.8 and made a part hereof (such commitments to
                   ------------                                            
attach copies of all instruments constituting exceptions to title), without
exceptions which do not materially adversely affect the use of the Owned
Properties for the purposes for which they are being used in the Business. Upon
receipt of such title commitments, Buyer shall provide a copy thereof to Seller.
Buyer may object to such title commitments on or prior to January 31, 1996 on
the basis that they materially adversely affect the use of the Owned Properties
for the purpose for which they are being used in the Business ("Title Defects")
whereupon Seller shall use reasonable efforts to cure any such objections to
title within sixty (60) days from receipt of written notice from Buyer of such
objections. If Buyer fails to so notify Seller within such twenty (20) day
period, Buyer shall be deemed to have accepted title to the Owned Properties in
their respective existing condition, provided that Seller shall in any event
satisfy all requirements shown in Schedule B - Section 1 of such title insurance
commitments (except as to the Prudential Loan, if assumed by Buyer in accordance
with Section 2.7 hereof). Notwithstanding any provision contained in this
Agreement to the contrary, expressed or implied, Seller's obligation to cure
Title Defects which requires the payment of money to cure the same shall be
limited to the payment of Two Hundred Thousand Dollars ($200,000) in the
aggregate, provided that such limitation shall not apply to the satisfying of
mortgages or liens. If any Title Defect is disclosed by Buyer to Seller and if
Seller fails to correct such Title Defect within the sixty (60) day period, then
Buyer shall have the option of (1) accepting the title as it then is, or (2)
terminating this Agreement pursuant to Section 8.15(iv) hereof, provided that if
all such Title Defects can be cured by the payment of money in an amount not to
exceed Two Hundred Thousand Dollars ($200,000) in the aggregate (less amounts
already expended by Seller to cure Title Defects), then the parties shall close
the transactions contemplated hereby and Buyer shall receive (x) a credit
against the Buyer's Notes, in the manner described in the last sentence of
Section 2.3(a)(ii), in an amount (but not to exceed $100,000) equal to one-half
of the amount necessary to cure such Title Defects; and (y) a credit against the
cash portion of the Purchase Price in an amount (but not to exceed $100,000)
equal to one-half of the amount necessary to cure such Title Defects. In no
event shall the total credit exceed $200,000 less amounts previously expended by
Seller to cure Title Defects. Survey defects shall be treated as objections to
title.

<PAGE>
 
          (b)  In addition to this Agreement, the Seller shall execute and 
deliver (in recordable form, when appropriate), any and all special warranty
deeds (in the form attached as Exhibit O), instruments or other documents of
                               ---------
transfer, conveyance and assignment (in form reasonably satisfactory to the
Seller and Buyer), and take such other action as Buyer may reasonably request,
as may be necessary or advisable to effect or evidence the transfers of the
Assets and the transactions contemplated hereby (including Seller's affidavit in
the form attached hereto as Exhibit P), as and to the extent contemplated
                            ---------
hereby. In addition to this Agreement, Buyer shall execute and deliver (in
recordable form, when appropriate), any and all instruments or other documents
of assumption and acceptance (in form reasonably satisfactory to Seller and
Buyer), and take such other action as the Seller may reasonably request, as may
be necessary or advisable to effect or evidence the assumption of the Assumed
Liabilities and the transactions contemplated hereby, as and to the extent
contemplated hereby. Seller shall pay all documentary, sales, use and transfer
taxes or fees imposed upon or incurred to procure the transfer of the Assets
(including but not limited to documentary taxes on all deeds conveying the Owned
Properties); provided, however, that Buyer shall pay one-half of such taxes or
fees applicable to the transfer of all motor vehicles included in the Assets.

          (c)  Buyer shall pay all documentary, intangible, and other taxes or
fees imposed upon the execution or recordation of the Buyer Notes and the
Security Instruments and all recordings fees for the recordation of the special
warranty deed(s).

     5.5  Employees.  The Buyer shall have the right, but not the obligation, to
          ---------                                               
offer employment, on terms and conditions to be set by the Buyer, to the
Employees of the Seller (whether or not such Employees' employment has been
theretofore terminated by Seller). No later than 10 days prior to the Closing,
Buyer shall advise Seller which of Seller's Employees Buyer will hire from and
after the Closing (it being understood that James A. Mercer shall be employed by
Buyer pursuant to the Mercer Employment Agreement attached hereto as Exhibit K 
                                                                     ---------
and, except for James A. Mercer, all of the Employees of Seller so hired by
Buyer shall be employees at will). Except as otherwise provided in this
Agreement, all such Employees so hired by Buyer shall be employed at such
salaries and with such benefits as Buyer shall determine.

          (a)  Except to the extent included in the Investment or the Assumed 
Liabilities, Seller shall remain liable and responsible for and pay all taxes,
for all time periods prior to and including the Closing Date, relating to
employee wages, salaries and benefits. Seller, to the extent required by law,
regulations or interpretations, shall be liable and responsible for all
obligations to give notice of and to provide health care continuation coverage
for Employees, Former Employees and their respective dependents and qualified
beneficiaries, in accordance with the requirements of COBRA (hereinafter
referred to as "COBRA Coverage"), including, without limitation, all
liabilities, taxes, sanctions, interest and penalties imposed upon, incurred by
or assessed against Buyer or any affiliated corporation within a controlled
group relationship with Buyer (as determined under Section 414 of the Code), and
any of their employees, arising by reason of or relating to any failure to
provide the COBRA Coverage, including, but not limited to, Buyer's failure to
provide COBRA Coverage to Employees or Former Employees who are receiving COBRA
Coverage under Seller's plans at the Closing Date. Buyer shall offer

                                       34
<PAGE>
 
immediate participation without any waiting period requirement in Buyer's group
health care plan to all salaried (but not hourly) Employees hired by Buyer.

          (b)  Except to the extent included in the Investment or the Assumed
Liabilities, Buyer expressly assumes no liabilities or obligations with respect
to any of the ERISA Plans, whether or not described or listed on any Schedule
attached hereto and whether or not such liabilities arise from the transactions
contemplated herein, including, without limitation, (i) health care continuation
liability under COBRA, and (ii) ERISA pension liability.

          (c)  Buyer hereby agrees to credit under its sick leave and vacation
policies the sick leave and vacation days accrued by Employees under the sick
leave and vacation policies of the Seller or its Affiliates (or their
predecessors) to the extent the same exceed the amount of sick leave and
vacation to which the Employees are entitled under Buyer's policies relating to
sick leave and vacation; provided, that Buyer shall not be obligated to credit
any Employee for any unused vacation time for calendar years prior to 1996 in
excess of 5 days carryover from calendar year 1995.
 
     5.6  Proxy Matters.   Each Seller acknowledges and agrees that it 
          -------------                                               
understands that, in connection with the transactions contemplated by a separate
agreement, and specifically the pending transaction (the "Calgene Transaction")
with Calgene, Inc. ("Calgene") an Affiliate of Buyer will be preparing and
filing with the Securities and Exchange Commission (the "SEC") a registration
statement (the "Registration Statement") under the Securities Act of 1933, 
as amended (the "Securities Act") and that Calgene will be preparing and filing
with the SEC a proxy statement (the "Proxy Statement") under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), in connection with
Calgene's solicitation of approval of the Calgene Transaction by its
stockholders. Each Seller further acknowledges and agrees that it understands
that the Registration Statement and the Proxy Statement will contain information
regarding the assets, liabilities, business and condition, financial and
otherwise, of the Seller and the Business. The Seller hereby agrees, at Buyer's
expense (except that preparation of the 1995 Financial Statements and
information and documentation relating to compliance with HSR shall be at
Seller's expense) to cooperate in all reasonable respects with Calgene, Buyer
and Buyer's Affiliates in their preparation of the information concerning Seller
and the Business for inclusion in the Registration Statement and Proxy Statement
and to use reasonable best efforts to furnish, or cause to be furnished, 
such information concerning the Seller and the Business as Calgene, Buyer and
Buyer's Affiliates may reasonably request in connection with their preparation
and filing of the Registration Statement and the Proxy Statement. Buyer shall
furnish to Seller a copy of the form of the Registration Statement and the 
Proxy Statement (and any amendment or supplement of either thereof) proposed 
to be filed with the SEC and provide Seller reasonable opportunity to review
same reasonably in advance of any filing thereof with the SEC and shall be
reasonably responsive to any comments or suggestions made by Seller regarding
the information contained therein concerning the Seller and the Business and
shall furnish Seller with a copy of the Registration Statement and the Proxy
Statement (and any amendment or supplement of either thereof) as such is filed
with the SEC.

     5.7  Seller's Representative.   Each Seller hereby irrevocably constitutes 
          -----------------------                                  
and appoints the Seller's Representative, with full power of substitution, as
such Person's attorney-in-fact with full irrevocable power and authority in the
place and stead of such Person and in the name of such Person or in the Seller's
Representative's own name, from time to time in the Seller's Representative's
reasonable discretion, for the purpose of carrying out the terms of this
Agreement, to take any and all appropriate action and to execute and deliver any
and all documents and instruments which the Seller's Representative may
reasonably deem necessary to accomplish the purposes of this Agreement. Without
limiting the generality of the foregoing, each such Person hereby gives the
Seller's Representative the power and right, on behalf of each such Person, to
do the following:

          (i)  agree with the Buyer as to the allocation of the Purchase Price 
               and Assumed Liabilities;

         (ii)  agree with the Buyer as to the Closing Date;

        (iii)  amend, change or modify the Agreement or any Transaction Document
               (to the extent such Person is a party thereto) before or after
               Closing;

         (iv)  receive any notice to any such Person relating to this Agreement 
               or any Transaction Document;

option, Buyer may (i) pay the Closing Date Cash Payment to the Seller's
Representative, (ii) make the Buyer's Notes payable to the Seller's
Representative and (iii) pay any other amount due by Buyer to Seller under this
Agreement to the Seller's Representative (including, without limitation, Gross
Crop Revenues and the Earn-Out Payment). The Seller's Representative shall be
responsible for allocating and transferring any amounts so received from Buyer
among the individual Sellers. Buyer's payment to the Seller's Representative of
any such amount shall fully discharge Buyer's obligation to make any such
payment to any Seller.

     (b)  Each Seller hereby ratifies, to the extent permitted by applicable 
law, all that Seller's Representative lawfully does or causes to be done by
virtue of this Section 5.7. The power of attorney granted pursuant to this
Section 5.7, being coupled with an interest, is irrevocable.

          (a)  any and all liabilities and obligations (other than

giving rise to Buyer's indemnification claim did not constitute a breach of the
representation and warranty made by Seller pursuant to Section 3.13 of this
Agreement.

     7.2  Buyer's Indemnity.  Subject to the provisions of this Article VII,
          -----------------

          (a)  any and all liabilities and obligations (other than

the indemnification liabilities and obligations of the Seller and the Buyer
pursuant to this Article VII shall survive the Closing for a period of three (3)
years, except that the indemnification liabilities and obligations of Seller and
Buyer under Section 7.1(d) and Section 7.2(e), respectively, shall survive the
Closing for a period of seven (7) years. The foregoing shall in no way limit
Buyer's obligations with respect to the Earn-Out.

     7.4  Method of Asserting Claims.   All claims for indemnification by any
          --------------------------                                         
Indemnified Party under this Article VII shall be asserted and resolved as
follows:

          (a)  If any claim or demand for which an Indemnifying Party would
be liable to an Indemnified Party hereunder is asserted against or sought to be
collected from such Indemnified Party by a third party, the Indemnified Party
shall with reasonable promptness notify the Indemnifying Party of such claim or
demand, specifying the nature of and specific basis for such claim or demand and
the amount or the estimated amount thereof to the extent then feasible (which
estimate shall not be conclusive of the final amount of such claim and demand)
(the "Claim Notice"). The Indemnifying Party shall not be obligated to indemnify
the Indemnified Party with respect to any such claim or demand if the
Indemnified Party fails to notify the Indemnifying Party thereof in accordance
with the provisions of this Agreement in reasonably sufficient time so that the
Indemnifying Party's ability to defend against the claim or demand is not
materially prejudiced. The Indemnifying Party shall have sixty (60) days from
the delivery of the Claim Notice (the "Notice Period") in accordance with the
provisions of this Agreement to notify the Indemnified Party, (i) whether or not
it disputes the liability of the Indemnifying Party to the 

                                       42
<PAGE>
 
Indemnified Party hereunder with respect to such claim or demand, and (ii)
notwithstanding any such dispute, whether or not it desires, at the sole cost
and expense of the Indemnifying Party subject to reimbursement if finally
determined not to be liable for indemnification, to defend the Indemnified Party
against such claim or demand; provided, however, that any Indemnified Party is
hereby authorized prior to and during the Notice Period to file any motion,
answer or other pleading which it shall deem necessary or appropriate to protect
its interests or those of the Indemnifying Party and not materially prejudicial
to the Indemnifying Party.

          (b)  If the Indemnifying Party disputes its liability with respect to 
such claim or demand or the amount thereof (if such amount is set out in the
Claim Notice) (whether or not such Indemnifying Party desires to defend the
Indemnified Party against such claim or demand as provided in paragraphs (c) and
(d) below), such dispute shall be resolved in accordance with paragraph (f)
hereof. Pending the resolution of any dispute by the Indemnifying Party of its
liability with respect to any claim or demand, such claim or demand shall not be
settled without the prior written consent of the Indemnifying Party.

          (c)  If the Indemnifying Party notifies the Indemnified Party within 
the Notice Period that it desires to defend the Indemnified Party against such
claim or demand then, except as hereinafter provided, the Indemnifying Party
shall have the right to defend against such claim or demand by all appropriate
proceedings, which proceedings shall be promptly settled or prosecuted by it to
a final conclusion; provided, however, the Indemnifying Party shall not, without
the prior written consent of the Indemnified Party, consent to the entry of any
judgment against the Indemnified Party or enter into any settlement or
compromise which does not include, as an unconditional term thereof, the giving
by the claimant or plaintiff to the Indemnified Party of a release, in form and
substance satisfactory to the Indemnified Party, from all liability in respect
of such claim or litigation. If the Indemnified Party desires to participate in,
but not control, any such defense or settlement, it may do so at its sole cost
and expense; provided, however, that if in the reasonable judgment of the
Indemnified Party there may be a conflict of interest between the Indemnifying
Party and the Indemnified Party in the conduct of the defense of such action,
the fees and expenses of such counsel to the Indemnified Party shall be at the
expense of the Indemnifying Party (unless the Indemnifying Party disputes its
liability with respect to such claim or demand and such dispute is resolved in
its favor). If requested by the Indemnifying Party, the Indemnified Party agrees
to cooperate with the Indemnifying Party and its counsel in contesting any claim
or demand which the Indemnifying Party elects to contest, or, if appropriate and
related to the claim in question, in making any counterclaim against the person
asserting the claim and any third party cross complaint against any person.

          (d)  (i)  If the Indemnifying Party elects not to defend the
Indemnified Party against such claim or demand, whether by not giving the
Indemnified Party timely notice as provided above or otherwise, then the amount
of any such claim or demand, or if the same be defended by the Indemnifying
Party or by the Indemnified Party (but the Indemnified Party shall not have any
obligation to defend any such claim or demand), then that portion thereof as to
which such defense is unsuccessful, in each case shall be conclusively deemed to
be a liability of the Indemnifying Party hereunder, unless the Indemnifying
Party shall have disputed its liability to 

                                       43
<PAGE>
 
the Indemnified Party hereunder, as provided in paragraph (a) above, in which
event such dispute shall be resolved in accordance with paragraph (f) hereof. No
claim may be settled without the consent of the Indemnifying Party.

              (ii)  In the event an Indemnified Party should have a claim
against an Indemnifying Party hereunder which does not involve a claim or demand
being asserted against or sought to be collected from it by a third party, the
Indemnified Party shall promptly send a Claim Notice with respect to such claim
to the Indemnifying Party.  If the Indemnifying Party disputes its liability
with respect to such claim or demand, such dispute shall be resolved in
accordance with paragraph (f) hereof.  If the Indemnifying Party does not notify
the Indemnified Party within the Notice Period that it disputes such claim, the
amount of such claim shall be conclusively deemed a liability of the
Indemnifying Party hereunder.

          (e)  Upon the final determination of the liability under this
Article VII, payment shall be made as provided in Section 7.5 (a) or (b), as
appropriate.

          (f)  If an Indemnifying Party timely disputes its liability with
respect to a claim or demand against it for indemnification in accordance with
paragraph (a) above, such dispute between the Indemnifying Party and the
Indemnified Party shall be settled by arbitration in Miami, Florida in
accordance with the rules of the American Arbitration Association. The
arbitration shall be conducted by three arbitrators, one of whom shall be
selected by the Indemnified Party, one of whom shall be selected by the
Indemnifying Party and the third of whom shall be selected by the two
arbitrators so chosen.  The fees of the arbitrators shall be paid by the losing
party, unless otherwise awarded by the arbitrators.  The arbitration award shall
be final, conclusive and binding on the parties and judgment thereon may be
entered and enforced in any court of competent jurisdiction.

          (g)  Seller will be entitled, at its election, to control any cleanup,
remediation or other proceeding with respect to which indemnity is sought under
Section 7.1(d) for Environmental Liability, provided that Seller acts diligently
in connection therewith and in accordance with all Requirements of Law.

     7.5  Limitations on Amounts.
          ---------------------- 

          (a)  Seller.  Except with respect to matters covered by Section 7.1(d)
               ------                                                     
or Excluded Liabilities, Seller will have no liability under this Article for
indemnification with respect to any matter which (i) constitutes an inaccuracy
or breach of any representation or warranty of Seller under this Agreement
(whether asserted under Section 7.1(b) or otherwise), or (ii) to the extent
relating to any failure to perform or comply, prior to the Closing Date,
constitutes a breach of a covenant or agreement made by the Seller or any
Affiliate of the Seller under Sections 5.1 and 5.6 of this Agreement, until the
cumulative and aggregate amount of the Damages relating to such matters exceeds
ONE HUNDRED THOUSAND DOLLARS ($100,000), and then only for the amount by which
such Damages exceed ONE HUNDRED THOUSAND DOLLARS ($100,000). Seller shall not be
obligated to indemnify any party 

                                       44
<PAGE>
 
pursuant to this Article after the aggregate amount of indemnifiable Damages
equals or exceeds the sum of TWENTY MILLION DOLLARS ($20,000,000) provided that
the foregoing limitation on Seller's indemnity obligation shall not apply to
"Excluded Indemnity Liabilities" and any indemnification payments made by Seller
to an Indemnified Party for Excluded Indemnity Liabilities shall not be counted
toward the $20,000,000 limitation described above (and instead shall be in
addition to such $20,000,000 maximum amount). For purposes hereof "Excluded
Indemnity Liabilities" shall mean Excluded Liabilities other than (i)
Environmental Liabilities described in Section 7.1(d), or (ii) any liability of
Seller to any person or entity which constitutes a breach of any representation
or warranty of Seller contained in this Agreement or a breach of a covenant of
Seller contained in Section 5.1 or 5.6 of this Agreement. All amounts payable by
Seller under this Article shall be paid as follows: first, by reducing the
outstanding principal amount and any accrued and unpaid interest on the Buyer
Notes, and second, by payment from Seller within ten (10) days after final
determination of the amount so payable in accordance with the provisions of 
this Article.

          (b)  Buyer.  Buyer shall not be obligated under this Article for
               -----                                                       
indemnification with respect to any matter which constitutes an inaccuracy or
breach of any representation or warranty of Buyer under Article IV of this
Agreement, but not including a matter covered by Section 7.2(e) and not
including a liability which constitutes an Assumed Liability or is included in
the Investment, after the aggregate amount of indemnifiable Damages therefor
equals or exceeds the sum of TWENTY MILLION DOLLARS ($20,000,000). All amounts
payable by Buyer under this Article shall be paid within ten (10) days after
final determination of the amount so payable in accordance with the provisions
of this Article.

     7.6  Offset.  If Seller fails to pay any amounts to Buyer that are owed
          ------                                                             
pursuant to this Article VII, Buyer may set-off any such amounts against the
amounts, if any, owed to Seller by Buyer pursuant to the Buyer Notes and the
Earn-Out Payment. Further, if litigation, arbitration or a Claim Notice has been
instituted which could give rise to an indemnification payment to Buyer, payment
of amounts, if any, owed Seller, pursuant to the Buyer Notes or the Earn-Out
Payment, shall be deposited into escrow by Buyer as provided below until such
litigation, arbitration or Claim Notice with respect to Seller's obligation to
indemnify Buyer is finally resolved.

          The amount to be deposited into escrow shall be limited to the
disputed portion of the claimed indemnification payment ("Disputed Amount") and
all other amounts owing by Buyer to Seller under the Buyer Notes and Earn-Out
Payment shall be timely paid. The Disputed Amount shall be deposited into an
interest-bearing escrow account at NationsBank of Florida, N.A., Naples, Florida
("Escrow Account") pursuant to an Escrow Agreement in the form attached hereto
as Exhibit L ("Escrow Agreement") and shall be disbursed as provided in such
   ---------                                                                
Escrow Agreement. The party entitled to the Disputed Amount or portion thereof
shall receive the same with the interest earned thereon. The other party shall
also pay to the receiving party an amount ("Additional Interest Amount") equal
to (a) in the case of a payment to Buyer, the difference between (i) the amount
of interest which would have been earned on the Disputed Amount, or portion
thereof, from the date it should have been paid to Seller calculated at the

                                       45
<PAGE>
 
prime lending rate of NationsBank of Florida, N.A. (or its successor) from time
to time in effect (the "Prime Rate"), and (ii) the amount of interest actually
earned on the Disputed Amount, or portion thereof, in the Escrow Account; and
(b) in the case of a payment to Seller, the difference between (i) the amount of
interest which would have been earned on the Disputed Amount, or portion
thereof, from the date it should have been paid to Seller calculated at the
greater of (x) three percent (3%) over the Prime Rate and (y) twelve percent
(12%), and (ii) the amount of interest actually earned on the Disputed Amount,
or portion thereof, in the Escrow Account. The Additional Interest Amount shall
be paid within ten (10) days after the Disputed Amount, or portion thereof, is
delivered to the applicable party.

    8.15  Termination.
          ----------- 

          (a)  This Agreement and the transactions contemplated hereby may be
terminated at any time prior to Closing by written notice delivered by Seller to
Buyer or by Buyer to Seller, as the case may be, in the following instances:

               (i)  By Buyer, if there has been a material misrepresentation, 
          a material breach of warranty or a material failure to comply on the
          part of the Seller with respect to any of the representations,
          warranties, covenants or provisions set forth herein (or delivered in
          any other document pursuant hereto), including without limitation, any
          misrepresentation, breach or failure to comply that is evidenced in
          any Schedule delivered by Seller, or which is discovered in Buyer's
          due diligence investigation of Seller and the Business, and such
          misrepresentation, breach or failure has or may reasonably be expected
          to have a Material Adverse Effect on the Business in the hands of
          Buyer and has not been cured, if capable of cure, in full within
          twenty (20) days of receipt by Seller of notice from Buyer.

              (ii)  By Seller, if there has been a material misrepresentation, 
          a material breach of warranty or a material failure to comply on the
          part of Buyer with respect to the representations, warranties or
          covenants set forth herein (or in any other document delivered
          pursuant hereto) and such misrepresentation, breach or failure to
          comply has not been cured, if capable of cure, within twenty (20) days
          of receipt by Buyer of notice from Seller.

             (iii)  At any time prior to Closing, by the mutual consent in 
          writing of Seller and Buyer.

              (iv)  by Buyer if Seller fails to correct a Title Defect to which 
          Buyer has objected pursuant to Section 5.4 within the sixty (60) day
          cure period provided therein, unless the provision of Section 5.4 for
          closing the transactions contemplated hereby with a credit against the
          Purchase Price is applicable.

               (v)  By Buyer or Seller, if the Closing does not occur on or 
          before the later of the end of the sixty (60) day cure period provided
          in Section 5.4 and February 28, 1996.

          (b)  Liability in the Event of Termination; Remedies.
               ----------------------------------------------- 

               (i)  In the event of termination of this Agreement and the 
          transactions contemplated hereby pursuant to Sections 8.15(a)(i) or
          (ii) hereof, the non-breaching party may avail itself of all rights,
          power and remedies now or hereafter existing at law or in equity or by
          statute or otherwise.

              (ii)  In the event of termination of this Agreement and the 
          transactions contemplated hereby pursuant to Section 8.15(a)(iii),
          (iv) or (v) hereof, this Agreement shall, with the exception of
          Section 8.14(b) hereof, become void and have no further effect,
          without any liability on the part of any party hereto.

          (c)  Section 8.14(b) hereof shall survive the termination of this
Agreement regardless of the reason for such termination.

    8.16  Radon Disclosure.   Radon is a naturally occurring radioactive gas
          ----------------                                                  
that, when it has accumulated in a building in sufficient quantities, may
present health risks to persons who are exposed to it over time.  Levels of
radon that exceed federal and state guidelines have been found in buildings in
Florida.  Additional information regarding radon and radon testing may be
obtained from the county public health unit.  The foregoing disclosure is
provided to comply with state law and is for informational purposes only.

    8.17  Remedies Cumulative.   All rights and remedies granted in this
          -------------------                                           
Agreement (including, without limitation, those granted under Article VII
hereof) or available under applicable law shall be deemed concurrent and
cumulative and not alternative or exclusive remedies, to the full extent
permitted by law and this Agreement, and any party may proceed with any number
of remedies at the same time or in any order (except that the set-off rights of
Buyer under Section 7.6 shall be exclusive; but only so long as the
indemnification obligations of Article VII are in effect).  The exercise of any
one right or remedy shall not be deemed a waiver or release of any other right
or remedy, and any party, upon the occurrence of an event of default by another
party under this Agreement, may proceed at any time, under any agreement, in any
order and with any available remedy.  Nothing in this Section shall affect the
termination of (i) indemnification liabilities and obligations pursuant to
Section 7.3, and (ii) the survival of representations and warranties and certain
covenants pursuant to Section 8.13.
