series of Preferred Stock that shall be designated as "Series A Convertible
Preferred Stock" (the "Series A Preferred"), and the number of shares
constituting such series shall be Two Hundred (200). Such number of shares
may be increased or decreased, but not to a number less than the number of
shares of Series A Preferred then issued and outstanding, by resolution
adopted by the full Board of Directors.

         SECTION 2.     DEFINITIONS. In addition to the definitions set forth
elsewhere herein, the following terms shall have the meanings indicated:

other entity or organization, other than the Corporation, any subsidiary of

         SECTION 3.     CERTAIN COVENANTS AND RESTRICTIONS.

         (a)     So long as any shares of Series A Preferred are outstanding;

                 (i)    At all times after the effective date of the Charter
         Amendment, the Corporation shall reserve and keep available for
         issuance upon the conversion of the shares of Series A Preferred such
         number of its authorized but unissued shares of Common Stock as will be
         sufficient to permit the conversion of all outstanding shares of Series
         A Preferred, and all other securities and instruments convertible into
         shares of Common Stock, and shall take all reasonable action within its
         power required to increase the authorized number of shares of Common
         Stock necessary to permit the conversion of all such shares of Series A
         Preferred and all other securities and instruments convertible into
         shares of Common Stock.

                 (ii)   The Corporation represents, warrants and agrees that all
         shares of Common Stock that may be issued upon exercise of the
         conversion rights of shares of Series A Preferred will, upon issuance,
         be fully-paid and nonassessable.

                 (iii)  The Corporation shall pay all taxes and other
         governmental charges (other than any income or franchise taxes) that
         may be imposed with respect to the issue or delivery of shares of
         Common Stock upon conversion of Series A Preferred as provided herein.
         The Corporation shall not be required, however, to pay any tax or other
         charge imposed in connection with any transfer involved in the issue of
         any certificate for shares of Common Stock in any name other than that
         of the registered holder of the shares of the Series A Preferred
         surrendered in connection with the conversion thereof, and in such case
         the Corporation shall not be required to issue or deliver any stock
         certificate until such tax or other charge has been paid, or it has
         been established to the Corporation's satisfaction that no tax or other
         charge is due.

         SECTION 4.     LIQUIDATION PREFERENCE.

         (a)     In the event of any liquidation, dissolution or winding up
of the Corporation (in connection with the bankruptcy or insolvency of the
Corporation or otherwise), whether voluntary or involuntary, before any
payment or distribution of the assets of the Corporation (whether capital or
surplus) shall be made to or set apart for the holders of shares of any
Junior Securities, the holders of the shares of Series A Preferred shall be
entitled to receive an amount equal to the Preference Amount, plus the amount
of any accrued and unpaid dividends on the Series A Preferred, multiplied by
the number of shares of Series A Preferred held by them. To the extent the
available assets are insufficient to fully satisfy such amounts, then the
holders of the Series A Preferred shall share ratably in such distribution in
the proportion that the number of each holder's Series A Preferred shares
bears to the total number of shares of Series A Preferred outstanding. No
further payment on account of any such liquidation, dissolution or winding up
of the Corporation shall be paid to the holders of the shares of Series A
Preferred or the holders of any Parity Securities unless there shall be paid
at the same time to the holders of the shares of Series A Preferred and the
holders of any Parity Securities proportionate amounts determined ratably in
proportion to the full amounts to which the holders of all outstanding shares
of Series A Preferred and the holders of all such outstanding Parity
Securities are respectively entitled with respect to such distribution. For
purposes of this Section 4, neither a consolidation or merger of the
Corporation with one or more partnerships, corporations or other entities nor
a sale, lease, exchange or transfer of all or any substantial part of the
Corporation's assets for cash, securities or other property shall be deemed
to be a liquidation, dissolution or winding-up of the Corporation, whether
voluntary or involuntary.

         (b)     Written notice of any liquidation, dissolution or winding up
of the Corporation, stating the payment date or dates when and the place or
places where the amounts distributable in such circumstances shall be
payable, shall be given by first class mail, postage prepaid, not less than
15 days prior to any payment date stated therein, to the holders of record of
the shares of Series A Preferred at their respective addresses as the same
shall appear in the records of the Corporation.

         SECTION 5.     DIVIDENDS. Holders of the Series A Preferred will be
entitled to receive, when, as and if declared by the Board of Directors, out
of funds legally available therefor, dividends payable at such rate as may be
determined by the Board of Directors; provided, however, that no dividend
shall be paid on Common Stock unless dividends shall have been paid to or
declared and set apart upon all shares of the Series A Preferred, at a rate
per share at least equal to the dividend payment on the Common Stock into
which each share of Series A Preferred is then convertible.

         SECTION 6.     REACQUIRED SHARES. Any shares of Series A Preferred
repurchased, converted or otherwise acquired by the Corporation shall be
retired and canceled promptly after the acquisition thereof. All such shares
shall upon their cancellation become authorized but unissued shares of
Preferred Stock, without designation as to series.

                                        3

<PAGE>

         SECTION 7.     VOTING RIGHTS.

         (a)     Except as otherwise required by law and as specified in this
Section 7, the holders of shares of Series A Preferred shall not have any
right or power to vote on or consent with respect to any matter or in any
proceeding or to be represented at any meeting of stockholders of the
Corporation. On any matters on which the holders of shares of Series A
Preferred shall be entitled to vote, they shall be entitled to one vote for
each share held.

         (b)     So long as any shares of Series A Preferred remain
outstanding, the affirmative vote or consent of the holders of a majority of
the shares of Series A Preferred outstanding at the time, given in person or
by proxy, either in writing or at a meeting, shall be necessary to permit,
effect or validate (i) the authorization, creation or issuance, or any
increase in the authorized or issued amount, of any class or series of Senior
Security or (ii) the amendment, alteration or repeal of any of the provisions
of the Certificate of Incorporation, as amended, of the Corporation which
would materially and adversely affect any right, preference, privilege or
voting power of shares of Series A Preferred or of the holders thereof. The
increase in the amount of authorized Preferred Stock of the Corporation or
the creation and issuance, or increase in amount of authorized shares of
other series of Parity Security or Junior Security shall not be deemed to
affect materially and adversely such rights, preferences, privileges or
voting power.

         SECTION 8.     CONVERSION RIGHTS. Holders of shares of Series A
Preferred shall have the right to convert, in whole or in part and without
the payment of any additional consideration by the holder, any or all of such
shares into Common Stock, as follows:

         (a)     At any time after the effective date of the Charter
Amendment, each share of Series A Preferred shall be convertible at the
option of the holder thereof into fully paid, non-assessable shares of Common
Stock. The number of shares of Common Stock deliverable upon conversion of
each share of Series A Preferred shall be 115,780.58, subject to adjustment
as provided in this Section.

         (b)     In case at any time the Corporation shall (i) subdivide the
outstanding shares of Common Stock into a greater number of shares, (ii)
combine the outstanding shares of Common Stock into a smaller number of
shares or (iii) pay a dividend in Common Stock on its outstanding shares of
Common Stock, then the number of shares of Common Stock that each share of
Series A Preferred in convertible into under Section 8(a) shall be multiplied
by the fraction obtained:

         by dividing

         (X), the actual total number of issued and outstanding shares of Common
         Stock immediately after the occurrence of such subdivision, combination
         or dividend,

         by

         (Y), the total number of issued and outstanding shares of Common Stock
         immediately prior to the the occurrence of such subdivision,
         combination or dividend.

Such adjustment shall become effective immediately after the occurrence of a
subdivision, combination or stock dividend.

                                        4

<PAGE>

         (c)     The conversion of any share of Series A Preferred may be
effected by the holder thereof by the surrender of the certificate or
certificates therefor, duly endorsed, at the principal offices of the
Corporation or to such agent or agents of the Corporation as may be
designated by the Board of Directors and by giving written notice to the
Corporation that such holder elects to convert the same.

         (d)     As promptly as practicable after the surrender of shares of
Series A Preferred for conversion, the Corporation shall issue and deliver or
cause to be issued and delivered to the holder of such shares certificates
representing the number of fully paid and non-assessable shares of Common
Stock into which such shares of Series A Preferred have been converted in
accordance with the provisions of this Section 8. Subject to the following
provisions of this Section, such conversion shall be deemed to have been made
as of the close of business on the date on which the shares of Series A
Preferred shall have been surrendered for conversion in the manner herein
provided, so that the rights of the holder of the shares of Series A
Preferred so surrendered shall cease at such time, and the person or persons
entitled to receive the shares of Common Stock upon conversion thereof shall
be treated for all purposes as having become the record holder or holders of
such shares of Common Stock at such time; PROVIDED, HOWEVER, that any such
surrender on any date when the stock transfer books of the Corporation are
closed shall be deemed to have been made, and shall be effective to terminate
the rights of the holder or holders of the shares of Series A Preferred so
surrendered for conversion and to constitute the person or persons entitled
to receive such shares of Common Stock as the record holder or holders
thereof for all purposes, at the opening of business on the next succeeding
day on which such transfer books are open.

         (e)     The Corporation shall not be required to issue fractional
shares of stock upon the conversion of the Series A Preferred. As to any
final fraction of a share which the holder of one or more shares of Series A
Preferred would otherwise be entitled to receive upon conversion, the
Corporation shall, in lieu of issuing any fractional share, pay the holder
otherwise entitled to such fraction a sum in cash equal to the same fraction
of $2.75 on the day of conversion, subject to appropriate adjustment for any
of the transactions described in Section 8(b).

         (f)     In case the Corporation shall be a party to any transaction
(including without limitation, a merger, consolidation, statutory share
exchange, sale of all or substantially all of the Corporation's assets or
recapitalization of the Common Stock), in each case as a result of which
shares of Common Stock shall be converted into the right to receive stock,
securities or other property (including cash or any combination thereof)
(each of the foregoing transactions being referred to as a "Fundamental
Change Transaction"), then the shares of Series A Preferred remaining
outstanding will thereafter no longer be subject to conversion into Common
Stock pursuant to this Section, but instead each share shall be convertible
into the kind and amount of stock and other securities and property
receivable (including cash) upon the consummation of such Fundamental Change
Transaction by a holder of that number of shares of Common Stock into which
one share of Series A Preferred was convertible immediately prior to such
Fundamental Change Transaction (including an immediate adjustment of the
Conversion Price if by reason of or in connection with such merger,
consolidation, statutory share exchange, sale or recapitalization any
securities are issued or event occurs which would, under the terms hereof,
require an adjustment of the Conversion Price). The provisions of this
Section 8(f) shall similarly apply to successive Fundamental Change
Transactions.

         (g)     If the Corporation proposes to take any action specified in
this Section 8 which requires any adjustment of the number of shares of
Common Stock that each share of Series A Preferred is convertible into under
Section 8(a) or proposes to effect a Fundamental Change Transaction, then and
in

                                        5

<PAGE>

each such case the Corporation shall at least 30 days prior to any such
event, and within five Business Days after it has knowledge of any such
pending transaction, provide to the Series A Preferred holders written notice
of the date on which the books of the Corporation shall close or a record
shall be taken for such dividend or for determining rights to vote in respect
of any such consolidation or merger. Such notice shall also specify, as
applicable, the date on which the holders of capital stock shall be entitled
thereto or the date on which the holders of capital stock shall be entitled
to exchange their stock for securities deliverable upon such Fundamental
Change Transaction, as the case may be. Such notice shall also state that the
action in question or the record date is subject to the effectiveness of a
registration statement under the Securities Act of 1933, as amended, or to a
favorable vote of security holders, if either is required. Furthermore, any
notice shall state the Conversion Price resulting from such adjustment and
the increase or decrease, if any, in the number of shares obtainable at such
price upon exercise, setting forth in reasonable detail the method of
calculation and the facts upon which such calculation is based. The failure
to give notice of any action or transaction as required under this Section
8(g) shall not affect the validity of any such action or transaction.

         SECTION 9.     RANKING. For purposes of the distribution of assets
upon liquidation, dissolution or winding up of the Corporation, (i) the
Junior Securities shall rank junior to the Series A Preferred and (ii) the
Parity Securities shall rank on a parity with the Series A Preferred.

         SECTION 10.    RECORD HOLDERS. The Corporation may deem and treat
the record holder of any shares of Series A Preferred as the true and lawful
owner thereof for all purposes, and the Corporation shall not be affected by
any notice to the contrary.

         SECTION 11.    NOTICE. Except as may otherwise be provided by law or
provided for herein, all notices referred to herein shall be in writing, and
all notices hereunder shall be deemed to have been given upon receipt, in the
case of a notice of conversion given to the Corporation, or, in all other
cases, upon the earlier of receipt of such notice or three Business Days
after the mailing of such notices sent by registered mail (unless first-class
mail shall be specifically permitted for such notice under the terms hereof)
with postage prepaid, addressed: If to the Corporation, to its principal
executive offices; or if to a holder of the Series A Preferred, to such
holder at the address of such holder of the Series A Preferred as listed in
the stock record books of the Corporation, or to such other address as the
Corporation or holder, as the case may be, shall have designated by notice
similarly given.

         SECTION 12.    SUCCESSORS AND TRANSFEREES. The provisions applicable
to shares of Series A Preferred shall bind and inure to the benefit of and be
enforceable by the Corporation, the respective successors to the Corporation,
and by any record holder of shares of Series A Preferred.

                  RESOLVED FURTHER, that the officers of the Corporation be, and
         they are hereby, authorized and directed from time to time to execute
         such certificates, instruments or other documents and do all such
         things as may be necessary or advisable in their discretion in order to
         carry out the terms hereof, including the filing with the Secretary of
         State for the State of Delaware of a copy of the foregoing resolution
         executed by an officer of the Corporation.

financial and other obligations to complete such transactions.

power and corporate authority to execute, deliver and perform this Agreement
and any ancillary documents relating to the transactions contemplated hereby
to which it is a party to consummate the transactions contemplated hereby and

                                       16
<PAGE>

Entity or any other person or entity is required to be made or obtained by any
Buyer or any of its Affiliates in connection with the execution, delivery and
performance of this Agreement and the consummation of the transactions
contemplated hereby, except (a) applicable requirements, if any, of the HSR Act,
(b) where failure to obtain such consent, approval, authorization or action, or
to make such filing or notification, either individually or in conjunction with
other such failures, would delay the consummation of the transactions
contemplated by this Agreement or have a material adverse effect on the ability
of either Buyer to consummate the transactions contemplated by this Agreement,
or (c) notification to the Federal Competition Commission (Comision Federal de
Competencia), and notification (post-closing) to the National Registry of
Foreign Investments (Registro Nacional de Inversiones Extranjeras).

         5.5   PURCHASE ENTIRELY FOR OWN ACCOUNT. Each Buyer understands that
the Subject Stock, the Preferred Shares, the Conversion Shares and the Common
Shares (the "Securities") are being offered and sold pursuant to an exemption
from registration contained in the Securities Act based in part upon Buyers'
representations contained in the Agreement. The Preferred Shares, the
Conversion Shares and the Common Shares will be acquired for investment for
the applicable Buyer's own account, not as a nominee or agent, and not with a
view to the resale or distribution of any part thereof, and that Buyers have
no present intention of selling, granting any participation in, or otherwise
distributing the same. In acquiring the Subject Stock, no Buyer is offering
or selling, and will not offer or sell, for BHC in connection with any
distribution of the Subject Stock, and neither of the Buyers has a participation
and will not participate in any such undertaking or in any underwriting of
such an undertaking except in compliance with applicable federal and state
securities laws. Neither of the Buyers has any contract, undertaking, agreement,
or arrangement with any person to sell, transfer or grant participations to the
person or to any third person, with respect to any of the Securities.

         5.6   DISCLOSURE OF INFORMATION. Each Buyer believes it has received
all the information it considers necessary or appropriate for deciding whether
to purchase the Securities. Each Buyer further represents that it has had an
opportunity to ask questions and receive answers from BHC regarding the terms
and conditions of the offering of the Securities and the business, properties,
prospects and financial condition of BHC. The foregoing, however, does not limit
or modify the representations and warranties of BHC in Article IV of this
Agreement or the right of Buyers to rely thereon.

         5.7   INVESTMENT EXPERIENCE. Each Buyer acknowledges that it is able
to fend for itself, can bear the economic risk of its investment, and has such
knowledge and experience in financial or business matters that it is capable of
evaluating the merits and risks of the investment in the Securities. Each Buyer
also represents it has not been organized for the purpose of acquiring the
Securities.

         5.8   RESTRICTED SECURITIES. Each Buyer understands that the Securities
it is purchasing are characterized as "restricted securities" under the federal
securities laws inasmuch as they are being acquired from BHC in a transaction
not involving a public offering and that under such laws and applicable
regulations such securities may not be resold without registration under the
Securities Act, except in certain limited circumstances. Each Buyer acknowledges
and agrees that the Preferred

                                       17

<PAGE>

Shares, the Conversion Shares and the Common Shares are subject to restrictions
on transfer as set forth in Section 7.13.

<PAGE>

                  (m) change any of the accounting principles or practices used
         by it, except for any change required by reason of a concurrent change

         6.3 RESTRICTIONS ON CERTAIN ACTIONS RELATING TO THE DNAP ASSETS.
Except as otherwise expressly provided in this Agreement, prior to the Second
Closing or the earlier termination of this Agreement, BHC shall not without the
prior consent of Savia:

                  (a) mortgage or pledge any of the DNAP Assets or create or
         suffer to exist any Encumbrance thereupon, other than the Permitted
         Encumbrances;

                  (b) sell, lease, transfer or otherwise dispose of, directly or
         indirectly, any of the DNAP Assets other than in the ordinary course of
         business consistent with past practice;

                  (c) amend, modify or change in any material respect any

         6.4 CERTAIN SALES. Without limiting Savia's rights under Sections 6.1,
6.2 and 6.3, the parties agree that, with Savia's consent if required, in the
event BHC or one of its subsidiaries sells, transfers or otherwise disposes of
any capital stock or assets of any of the Fresh Produce Companies or any of the
DNAP Assets (other than to BHC or one of its subsidiaries), in each case
outside the ordinary course of business consistent with past practice, then BHC
shall cause cash proceeds of any such sale, transfer or disposition (up to an
aggregate of $48 million) to be paid promptly to Savia as a return of a portion
of the Savia Advances, and the Purchase Price shall be reduced by the amount of
such proceeds (and only by such amount, notwithstanding any values allocated to
any of such capital stock or assets). In the event, and to the extent, that any
such proceeds exceed $48 million in the aggregate, then notwithstanding
anything to the contrary herein, BHC shall be permitted to transfer such excess
proceeds out of the Fresh Produce Companies or otherwise retain such excess
proceeds. To the extent any DNAP Assets are sold in accordance with this
Section 6.4, then such DNAP Assets shall thereafter be deemed excluded from the
term DNAP Assets as used in this Agreement.

                                   ARTICLE VII

                              ADDITIONAL AGREEMENTS

         7.1 ACCESS TO INFORMATION.

         (a) Between the date hereof and the Second Closing or the earlier
termination of this Agreement, BHC (i) shall give Buyers and their authorized
representatives reasonable access, during regular business hours and upon
reasonable advance notice, to such employees, plants, offices,

                                       20
<PAGE>

warehouses, and other facilities, and such books and records of the Fresh
Produce Companies, as are reasonably necessary to allow Buyers and their
authorized representatives to make such inspections as they may reasonably
require to verify the accuracy of any representation or warranty contained in
Article IV and (ii) shall cause BHC's officers and those of the Fresh Produce
Companies to furnish Buyers and their authorized representatives with such
financial and operating data and other information with respect to the Fresh
Produce Companies or the DNAP Assets as Buyers may from time to time reasonably
request; provided, however, that BHC shall have the right to have a
representative present at all times of any such inspections, interviews, and
examinations conducted at or on the offices or other facilities or properties
of BHC or the Fresh Produce Companies. Buyers shall indemnify, defend and hold
harmless BHC from and against any Losses asserted against or suffered by BHC
relating to, resulting from or arising out of examinations or inspections made
by any Buyer or its authorized representatives pursuant to this Section 7.1(a).

         (b) Each Buyer agrees that all Confidential Information shall be kept
confidential by such Buyer and shall not be disclosed by such Buyer in any
manner whatsoever; provided, however, that (i) any of such Confidential
Information may be disclosed to such directors, officers, employees, and
authorized representatives (including without limitation attorneys,
accountants, consultants, bankers, and financial advisors) of such Buyer
(collectively, for purposes of this Section, "Savia Representatives") as need
to know such information for the purpose of evaluating the transactions
contemplated hereby (it being understood that such Savia Representatives shall
be informed by Buyers of the confidential nature of such information and shall
be required to treat such information confidentially), (ii) any disclosure of
Confidential Information may be made to the extent to which BHC consents in
writing, and (iii) Confidential Information may be disclosed by Buyers or any
Savia Representative to the extent that, in the opinion of counsel for Buyers
or such Savia Representative, the applicable Buyer or such Savia Representative
is legally compelled to do so, provided that, prior to making such disclosure,
such Buyer or such Savia Representative, as the case may be, advises and
consults with BHC regarding such disclosure and provided further that such
Buyer or such Savia Representative, as the case may be, discloses only that
portion of the Confidential Information as is legally required. Each Buyer
agrees that none of the Confidential Information will be used for any purpose
other than in connection with the transactions contemplated hereby. The term
"Confidential Information," as used herein, means all information (irrespective
of the form of communication) obtained by or on behalf of any Buyer from BHC or
its representatives pursuant to this Section and all similar information
obtained from BHC or its representatives by or on behalf of any Buyer prior to
the date of this Agreement, other than information which (i) was or becomes
generally available to the public other than as a result of disclosure by any
Buyer or any Savia Representative, or (ii) was or becomes available to Buyers
on a nonconfidential basis prior to disclosure to any Buyer by BHC or its
representatives. If this Agreement is terminated, Buyers shall promptly return,
and shall use their reasonable best efforts to cause all Savia Representatives
to promptly return, all Confidential Information to BHC without retaining any
copies thereof, provided that such portion of the Confidential Information as
consists of notes, compilations, analyses, reports, studies, or other documents
prepared by any Buyer or Savia Representatives shall be destroyed.

         (c) Buyers agree that BHC may retain, subsequent to the consummation
of the transactions contemplated hereby, (i) copies of any books and records
which may be relevant in

                                       21
<PAGE>

connection with the defense of (A) the matters referred to in Article XII or
(B) disputes arising hereunder; and (ii) all consolidating and consolidated
financial information and all other accounting books and records prepared or
used in connection with the preparation of financial statements of BHC or any
parent company of any of the Fresh Produce Companies.

         (d) The applicable Buyer agrees that, subsequent to the consummation
of the transactions contemplated hereby, it shall preserve and keep all books
and records relating to the business or operations of the Fresh Produce
Companies on or before the Second Closing Date in such Buyer's possession for a
period of at least 10 years after the Second Closing Date. Notwithstanding the
foregoing, the applicable Buyer agrees that it shall preserve and keep all
books and records of the Fresh Produce Companies relating to any investigation
instituted by a Governmental Entity or any litigation (whether or not existing
on the Second Closing Date) if any possibility exists that such investigation
or litigation may relate to matters occurring prior to the Second Closing,
without regard to the 10-year period set forth in this Section 7.1(d).

         (e) Each party agrees that it will cooperate with and make available
to the other party (including without limitation the right to make copies),
during normal business hours, all books and records, information and employees
(without substantial disruption of employment) retained and remaining in
existence after the Second Closing Date which are necessary or useful in
connection with (i) any Tax inquiry, audit, investigation or dispute, (ii) any
litigation or investigation, or (iii) any other matter requiring any such books
and records, information or employees for any reasonable business purpose. The
party requesting any such books and records, information or employees shall
bear all of the out-of-pocket costs and expenses (including, without
limitation, attorneys' fees and reimbursement for the reasonable salaries and
employee benefits for those employees who are made available) reasonably
incurred in connection with providing such books and records, information or
employees. BHC may require certain financial information relating to the Fresh
Produce Companies' businesses for periods prior to the Second Closing Date for
the purpose of filing federal, state, local and foreign Tax returns and other
governmental reports, and each Buyer agrees to furnish such information to BHC
at BHC's request and expense.

         7.2 REGULATORY AND OTHER AUTHORIZATIONS; CONSENTS.

         (a) Each party hereto shall use all commercially reasonable efforts to
obtain all authorizations, consents, orders and approvals of, and to give all
notices to and make all filings with, all Governmental Entities (including but
not limited to those pertaining to the Governmental Approvals) and other third
parties that may be or become necessary for its execution and delivery of, and
the performance of its obligations pursuant to this Agreement and will
cooperate fully with the other party in promptly seeking to obtain all such
authorizations, consents, orders and approvals, giving such notices, and making
such filings. To the extent required by the HSR Act, each of the parties hereto
shall (i) file or cause to be filed, as promptly as practicable but in no event
later than 15 days after (x) the execution and delivery of this Agreement or
(y) such later date as a change of circumstances causes such a filing to be
required, with the Federal Trade Commission and the United States Department of
Justice, all reports and other documents required to be filed by such party
under the HSR Act concerning the transactions contemplated hereby and (ii)
promptly comply with or cause to be complied with any requests by the Federal
Trade Commission or the United States

                                       22
<PAGE>

Department of Justice for additional information concerning such transactions,
in each case so that the waiting period applicable to this Agreement and the
transactions contemplated hereby under the HSR Act shall expire as soon as
practicable after the execution and delivery of this Agreement. Each party
hereto agrees to request, and to cooperate with the other party or parties in
requesting, early termination of any applicable waiting period under the HSR
Act. Savia shall pay the filing fees payable in connection with the filings by
the parties required by the HSR Act.

         (b) Each Buyer will use its best efforts to assist BHC in obtaining
any consents of third parties necessary or advisable in connection with the
transactions contemplated by this Agreement.

         7.3 EMPLOYEE AND EMPLOYEE BENEFIT PLAN MATTERS.

         (a) Savia acknowledges and agrees that the Fresh Produce Companies
shall have no obligation to terminate any of the employees of the Fresh Produce
Companies (the "Fresh Produce Employees") prior to the Second Closing, and that
the Fresh Produce Companies shall be obligated to pay all amounts due to any
Fresh Produce Employee terminated in connection with or following the Second
Closing, including without limitation any severance pay. Following the Second
Closing, Savia agrees to cause the Fresh Produce Companies to make all such
payments and to indemnify and hold harmless BHC and its affiliates from and
against any claims by Fresh Produce Employees relating to the termination of
any of the Fresh Produce Employees by the Fresh Produce Companies, Savia or any
of its affiliates.

         (b) Within five days after the Second Closing, Savia, on behalf of
BHC, will notify all Fresh Produce Employees, (i) that the Second Closing has
occurred and (ii) as provided in BHC's 1998 Long-Term Incentive Plan, (A) that
all unvested options to purchase Common Stock which have been issued to Fresh
Produce Employees who do not continue in an employment position in BHC or one
of its subsidiaries subsequent to the Second Closing vested as of the Second
Closing Date and (B) such Fresh Produce Employees have three months from the
Second Closing to exercise any vested options to purchase Common Stock. Prior
to the Second Closing, BHC shall take all corporate action necessary to cause
all unvested options of the Fresh Produce Employees who do not continue in an
employment position in BHC or one of its subsidiaries subsequent to the Second
Closing to become vested as of the Second Closing Date.

         7.4 STOCKHOLDER MEETING; PROXY STATEMENT.

         (a) BHC shall take all action necessary in accordance with Applicable
Law, its Certificate of Incorporation and it bylaws duly to call, give notice
of, convene and hold the annual or a special meeting of its stockholders (the
"Stockholder Meeting") as promptly as practicable after the date hereof. At the
Stockholder Meeting, the stockholders of BHC will be asked (i) to adopt and
approve an amendment to BHC's Certificate of Incorporation to increase the
number of shares of Common Stock authorized thereunder from 50,000,000 to at
least 70,000,000 (the "Charter Amendment") and (ii) to approve the sale of the
Fresh Produce Companies as contemplated by this Agreement and (iii) if
applicable, any other matters required by Applicable Law or any national
securities exchange or interdealer quotation system. The stockholder vote
required for the adoption and approval of such matters shall be the vote
required by the Delaware General Corporation Law and BHC's Certificate

                                       23
<PAGE>

of Incorporation. The Board of Directors of BHC shall, subject to its fiduciary
obligations under Applicable Law as advised by counsel, recommend to the
stockholders of BHC that they vote in favor of the adoption and approval of the
Charter Amendment and of this Agreement and the transactions contemplated
hereby. BHC will use its reasonable best efforts to solicit from the
stockholders of BHC proxies in favor of such approval and take all other action
commercially reasonably necessary to secure a vote of the stockholders of BHC
in favor of such adoption and approval. In the event that the stockholders of
BHC approve the Charter Amendment, BHC shall take all actions necessary to
implement the Charter Amendment as promptly as reasonably practicable.

         (b) Savia shall cause International (and any other affiliates of Savia
which own Common Stock) to vote and International shall vote (including the
taking of any action by written consent, as necessary or appropriate) all
shares of Common Stock which it is entitled to vote (or control the voting of,
directly or indirectly) at the Stockholder Meeting in favor of the matters
described in Section 7.4(a).

         (c) BHC shall prepare, shall file with the SEC under the Exchange Act,
and shall use its reasonable best efforts to have cleared by the SEC, and
promptly thereafter shall mail to its stockholders, a proxy statement with
respect to the Stockholder Meeting. The term "Proxy Statement," as used herein,
means such proxy statement and all related proxy materials and all amendments
and supplements thereto, if any. Except to the extent otherwise determined in
good faith by the Board of Directors of BHC in the exercise of its fiduciary
duties, taking into account the advice of counsel and as provided by Section
7.15, the Proxy Statement shall contain the recommendation of the Board that
the stockholders of BHC vote in favor of the matters described in Section
7.4(a). BHC and Savia shall cooperate with each other in preparing the Proxy
Statement, and each of BHC and Savia shall use its reasonable best efforts to
obtain and furnish the information required to be included in the Proxy
Statement. Each of BHC and Savia agrees promptly to correct any information
provided by it for use in the Proxy Statement if and to the extent that such
information shall have become false or misleading in any material respect, and
BHC further agrees to take all steps necessary to cause the Proxy Statement as
so corrected to be filed with the SEC and to be disseminated promptly to
holders of shares of the Common Stock, in each case as and to the extent
required by Applicable Law.

         7.5 RIGHTS OFFERING; REGISTRATION STATEMENT. The obligations of BHC
under this Section 7.5 shall be subject to consummation of the transactions
contemplated by this Agreement to be consummated at the First Closing, as well
as to the other terms and conditions of this Agreement.

         (a) Subject to the effectiveness of the Registration Statement
(defined below), BHC will distribute to each record holder of Common Stock, as
of a record date to be set by BHC, two rights (the "Rights") for every one
share of Common Stock held by such record holder. Each Right will entitle the
holder to purchase one share of Common Stock at an exercise price of $2.50 per
share. Rights to purchase fractional shares will not be issued; the number of
Rights issued to each stockholder will be rounded up to the next whole number.
The Rights will expire 60 days after issuance or at such other time as Savia
and the Special Committee of the BHC Board of Directors may agree. As used
herein, the term "Rights Offering" means the transactions described in this

                                       24
<PAGE>

Section 7.5(a). The parties agree that the Rights Offering may commence prior
to the Second Closing and end after the Second Closing.

         (b) BHC shall file an amendment to BHC's Registration Statement on
Form S-3 (No. 333-76759), or file a new registration statement, for the purpose
of registering under the Securities Act the offering, sale and delivery of the
Common Stock issuable in the Rights Offering (in lieu of the rights described
in such registration statement as currently on file), which shall not include
the Common Stock that would be issuable upon exercise of the Rights which will
be surrendered pursuant to Section 7.5(c). The term "Registration Statement,"
as used herein, means such amended or new registration statement and all
amendments and supplements thereto, if any. BHC shall use its reasonable best
efforts to have the Registration Statement declared effective under the
Securities Act as promptly as practicable after the First Closing. BHC, after
consultation with Savia, shall use its reasonable best efforts to respond
promptly to any comments made by the SEC with respect to the Registration
Statement. If and to the extent that the information contained in the
Registration Statement shall have become false or misleading in any material
respect, BHC further agrees to take all steps necessary to cause the
Registration Statement (or the prospectus contained therein) as so corrected to
be filed with the SEC and to be disseminated to the extent required by
Applicable Law. BHC shall also take any action (other than qualifying to do
business in any jurisdiction in which it is not now so qualified) reasonably
required to be taken under any applicable state securities laws in connection
with the issuance of securities pursuant to the Registration Statement.

         (c) Upon issuance of the Rights, Savia shall cause International to
surrender, and International shall surrender, immediately to BHC at no cost to
Bionova, all Rights received by International.

         7.6 AMEX LISTING. BHC shall use its reasonable best efforts to cause
the shares of Common Stock issuable upon exercise of the Rights to be approved
for listing on the American Stock Exchange (or such other stock exchange on
which the Common Stock is then listed), subject to official notice of issuance
prior to the consummation of the Rights Offering.

         7.7 PUBLIC ANNOUNCEMENTS. Buyers, on the one hand, and BHC, on the
other, shall consult with each other before they or any of their respective
affiliates issue any press release or otherwise make any public statement with
respect to this Agreement or the transactions contemplated hereby, and neither
of them or any such affiliate shall issue any such press release or make any
such public statement prior to such consultation (but no approval thereof shall
be required), except as may be required by law or regulation.

         7.8 INTERCOMPANY ACCOUNTS. On or before the Second Closing Date, BHC
and the Fresh Produce Companies shall have executed and delivered such
agreements and instruments as may be necessary or appropriate to cause all
Intercompany Accounts existing immediately prior to the Second Closing between
BHC and the Fresh Produce Companies to have been eliminated for no
consideration.

         7.9 FEES AND EXPENSES. Except as otherwise expressly provided in this
Agreement, all fees and expenses, including fees and expenses of counsel,
financial advisors, and accountants,

                                       25
<PAGE>

incurred in connection with this Agreement and the transactions contemplated
hereby shall be paid by Savia, whether or not the First Closing or Second
Closing shall have occurred; provided, however, that all fees and expenses
incurred by the BHC Board of Directors in conjunction with its Special
Committee of Independent Directors (financial advisors, counsel, etc.) and the
normal expenses associated with the Annual Meeting of Stockholders to approve
the transactions and any fees paid to increase the authorized shares of BHC
will be paid by BHC.

         7.10 TRANSFER TAXES. All sales, transfer, filing, recordation,
registration and similar taxes and fees arising from or associated with the
transactions contemplated hereunder, whether levied on Savia or BHC, shall be
borne by Savia, and Savia shall file all necessary documentation with respect
to, and make all payments of, such taxes and fees on a timely basis. The
parties shall cooperate in obtaining available exemptions with respect to the
foregoing taxes and fees.

         7.11 SUBSEQUENT TRANSACTIONS. If BHC, either directly or through a
subsidiary, enters into a Significant Transaction (as such terms are defined
below) prior to February 15, 2001, and such Significant Transaction has not
been terminated or abandoned, then (i) BHC shall notify the Special Committee
of the BHC Board of Directors of such Significant Transaction and (ii) the
Special Committee of the BHC Board of Directors may take such actions as it
deems necessary to consider the impact, if any, of the proposed Significant
Transaction on its recommendation regarding the transactions contemplated by
this Agreement, including without limitation requesting from its financial
advisors an updated fairness opinion that takes into account the proposed
Significant Transaction. If, as a result of such action of the Special
Committee of the BHC Board of Directors, the Special Committee of the BHC Board
of Directors withdraws its recommendation to the Board of Directors of BHC of
the transactions contemplated by this Agreement (including the terms of the
Series A Preferred), then BHC and the Buyers shall use their reasonable best
efforts to modify the terms of the transactions contemplated by this Agreement
to arrive at terms that can be favorably recommended by the Special Committee
of the BHC Board of Directors.

         For purposes of this Section 7.11, BHC shall be deemed to have
"entered into" a Significant Transaction if it (i) enters into an agreement
relating to, (ii) publicly announces, or (iii) is actively involved in
negotiations concerning, a Significant Transaction; provided, however, that an
agreement dealing only with confidentiality and other preliminary matters shall
not be considered an agreement for purposes of clause (i) of this sentence.

         For purposes of this Section 7.11, a "Significant Transaction" means a
merger, consolidation, or other business combination or extraordinary
transaction involving BHC and another Person (including without limitation the
direct or indirect acquisition by BHC of a majority of the ownership interests
or all or substantially all of the assets of another Person or the acquisition
by another Person of a majority of the capital stock of BHC or all or
substantially all of the assets of BHC).

         7.12 INSURANCE. Each Buyer acknowledges and agrees that, upon the
occurrence of, or immediately following, the Second Closing, the policies of
insurance BHC maintains for the Fresh Produce Companies with respect to their
respective assets and operations will be terminated or modified to exclude
coverage of all or any portion of the Fresh Produce Companies or the DNAP
Assets by BHC in its sole discretion, and, as a result, the applicable Buyer
shall be obligated at or

                                       26
<PAGE>

before Second Closing to obtain at its sole cost and expense replacement or
substitute insurance coverage with similar policies and amounts of coverage.
Each Buyer further acknowledges and agrees that Buyers will need to provide to
certain Governmental Entities and third parties evidence of such replacement or
substitute insurance coverage for the continued operations of the businesses of
the Fresh Produce Companies following the Second Closing.

         7.13 TRANSFER RESTRICTIONS.

         (a) Each Buyer, as applicable, agrees that it will not, directly or
indirectly, sell, assign, transfer, pledge, encumber, or otherwise dispose of
any of the Preferred Shares, the Conversion Shares or the Common Shares except:

                  (i)   In compliance with Rule 144; provided, however, that
         Buyer shall provide BHC with copies of all filings made with the SEC
         with respect to sales of securities under Rule 144 and with such other
         information and documents as BHC shall reasonably require in order to
         assure full compliance with Rule 144;

                  (ii)  Pursuant to a no-action letter or other interpretive
         statement or release of the SEC to the effect that the proposed sale or
         other disposition may be effected without registration under the
         Securities Act;

                  (iii) Pursuant to an applicable exemption (other than Rule
         144) under the Securities Act; provided, however, that Buyer shall have
         furnished BHC with evidence satisfactory to BHC (which, in the
         discretion of BHC, may include an opinion of counsel, which opinion and
         counsel shall be reasonably acceptable to BHC) to the effect that such
         disposition does not require registration of such securities under the
         Securities Act; or

                  (iv)  Pursuant to an effective  registration  statement  filed
         under the Securities Act.

         (b) International further agrees that it will not, directly or
indirectly, sell, assign, transfer, pledge, encumber, or otherwise dispose of
any of the Preferred Shares, without the prior written consent of BHC;
provided, however that International shall be permitted to transfer the
Preferred Shares to an affiliate (as defined in Rule 405 under the Securities
Act) of International if such affiliate shall have furnished BHC with the
representations contained in Sections 5.5 through 5.8 and this Section 7.13 of
this Agreement and shall have agreed with BHC to be subject to the terms of
this Agreement to the same extent as if it was an original holder of Preferred
Shares pursuant hereto. Any attempted transfer in violation of this Section
7.13 shall be void.

         7.14 REGISTRATION RIGHTS AGREEMENT. BHC, Savia and International shall
enter into a registration rights agreement (the "Registration Agreement") at
(and subject to the occurrence of) the Second Closing pursuant to which BHC
shall agree to register the Conversion Shares, the Common Shares and any shares
of Common Stock purchased by Savia pursuant to the Cash Support Agreement under
the Securities Act on the terms and subject to the conditions set forth
therein. The Registration Agreement shall be in substantially the form set
forth as EXHIBIT 7.14.

         7.15     ACQUISITION PROPOSALS.

                  (a) BHC will notify Savia within one Business Day of receipt
         of any proposals by, request for any information from, or initiation of
         or attempt or request to initiate any negotiations or discussions with,
         BHC or its officers, directors, employees, investment bankers,
         attorneys, accountants or other agents, in each case in connection with
         any Acquisition Proposal (as defined below) or the consideration of
         making of an Acquisition Proposal ("Acquisition Proposal Interest")
         indicating, in connection with such notice, the terms and conditions of
         any Acquisition Proposals or offers. BHC agrees that it shall keep
         Savia informed, on a reasonably current basis, of the status and terms
         of any Acquisition Proposal Interest. The term "Acquisition Proposal,"
         as used herein, means any offer or proposal for, or any indication of
         interest in, a merger or other business combination with any Fresh
         Produce Company, or the acquisition of any equity interest in, or a
         substantial portion of the assets of, any Fresh Produce Company, or the
         acquisition of a substantial portion of the DNAP Assets, other than the
         transactions contemplated by this Agreement.

                  (b) Except as provided in Section 7.15(c) or 7.15(d) or with
         the written consent of Savia, from the date hereof until this Agreement
         is terminated in accordance with its terms, BHC shall not, and shall
         use its reasonable efforts to ensure that its directors, officers,
         employees, investment bankers, attorneys, accountants or other agents
         shall not, directly or indirectly (i) solicit, initiate or knowingly
         encourage, or take any action to facilitate the making of, any
         Acquisition Proposal, (ii) enter into any agreement with respect to any
         Acquisition Proposal or (iii) engage in discussions or negotiations
         with, or provide any information relating to BHC to any person relating
         to an Acquisition Proposal; provided, however, that nothing contained
         in this Section 7.15 shall prohibit BHC or its Board of Directors from
         taking and disclosing to BHC's stockholders its position with respect
         to a tender or exchange offer by a third party pursuant to Rules 14d-9
         and 14e-2 under the Exchange Act to the extent required by Applicable
         Law.

                  (c) Notwithstanding the foregoing, BHC may furnish information
         concerning its business, properties or assets to any person and may
         negotiate and participate in discussions and negotiations with such
         person concerning an Acquisition Proposal if such entity or group has
         submitted a bona fide written proposal to BHC relating to any such
         transaction which BHC's Board of Directors determines in good faith,
         after receiving advice from the financial advisors representing the
         Special Committee of the BHC Board of Directors comprised of
         independent directors, represents a financially superior transaction to
         the transactions contemplated by this Agreement from the standpoint of
         the stockholders of BHC other than Savia and its affiliates and other
         than the officers and directors of BHC (an Acquisition Proposal which
         satisfies this requirement being referred to herein as a "Superior
         Proposal").

                  (d) Without the written consent of Savia, except as set forth
         herein, neither BHC's Board of Directors nor any committee thereof
         shall (i) withdraw or modify, or propose to withdraw or modify, in a
         manner adverse to Savia, the approval or recommendation by such Board
         of Directors or any such committee of this Agreement or the
         transactions contemplated hereby, (ii) approve or recommend or propose
         to approve or

                                       28
<PAGE>

         recommend, any Acquisition Proposal or (iii) enter into any agreement
         with respect to any Acquisition Proposal. Notwithstanding the
         foregoing, BHC's Board of Directors may (subject to the terms of this
         sentence and the following sentence) terminate this Agreement in
         accordance with Section 10.2(d) and enter into an agreement with
         respect to a Superior Proposal, in which event BHC may take any of the
         actions set forth in clauses (i) through (iii) of the immediately
         preceding sentence; provided, however, that BHC shall not enter into an
         agreement with respect to a Superior Proposal unless BHC shall have
         furnished Savia with written notice not later than 12:00 noon two
         Business Days in advance of any date that it intends to enter into such
         agreement and afford Savia an opportunity to make a proposal that is
         superior to such Superior Proposal.

agreements or fulfillment of any conditions to its own obligations contained
herein; provided, however, that any material matter must be approved by the
Special Committee of the BHC Board of Directors comprised of independent
directors. Any agreement on the part of a party hereto to any such waiver shall
be valid only if set forth in an instrument in writing signed by or on behalf of
such party. No failure or delay by a party hereto in exercising any right, power
or privilege hereunder shall operate as a waiver thereof nor shall any single or
partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege.

         10.6  SECOND CLOSING MATTERS. It is the intent of the parties that the
transactions contemplated by Section 2.1, on the one hand, and by Section
2.2(c), on the other hand, shall in appropriate circumstances be treated
separately for purposes of Articles VIII, IX and X. By way of example, a party's
termination of this Agreement with respect to the transactions contemplated by
Section 2.1 shall not of itself terminate the parties' agreements with respect
to the transactions contemplated by Section 2.2(c).

                                   ARTICLE XI

                                   TAX MATTERS

         11.1  TAX ALLOCATION: PRE-CLOSING. BHC shall be solely liable for and
shall pay all federal income Taxes of the Fresh Produce Companies (and any costs
or expenses connected therewith) due for all taxable years and periods ending on
or before the Second Closing Date (the "Pre-Closing Tax Period") and all other
Taxes for periods ending on December 31, 2000. BHC will include the taxable
income or loss of the Fresh Produce Companies on BHC's federal consolidated
income tax returns for any Pre-Closing Tax Period to the extent required under
Treasury Regulation Section 1.1502-76(b). The taxable income or loss of the
Fresh Produce Companies for the taxable year that includes the Second Closing
Date will be apportioned up to and including the Second Closing Date by
closing the books of the Fresh Produce Companies as of the Second Closing
Date pursuant to Treasury Regulation Section 1.1502-76(b). BHC will prepare
and file or cause to be prepared and filed all federal income Tax Returns for
the Fresh Produce Companies that are required to be filed with the
appropriate Governmental Entities for any Pre-Closing Tax Period and all
other Taxes for periods ending on December 31, 2000; provided, however, that
BHC shall furnish copies of such returns to Savia for its review, at least 10
days prior to filing.

         11.2  TAX ALLOCATION: POST-CLOSING. Savia shall be solely liable for
and shall pay all Taxes of the Fresh Produce Companies (and any costs or
expenses connected therewith) due for any taxable year or taxable period
commencing after the Second Closing Date (a "Post-Closing Tax Period").

                                       34
<PAGE>

Savia will prepare and file or cause to be prepared and filed all Tax Returns
for the Fresh Produce Companies that are required to be filed with the
appropriate Governmental Entities for any Post- Closing Tax Period. Savia will
make or cause to be made all payments shown thereon as owing with respect to any
such Tax Returns.

         11.3  [Intentionally omitted.]

         11.4  CORPORATE RECORDS. Section 7.1 shall apply with respect to the
parties' access to Tax information, except that notwithstanding Section 7.1,
Savia shall preserve or cause to be preserved, and retain or cause to be
retained, all returns, schedules, work papers, and all material records or other
documents relating to any such Tax Returns until the expiration of the statutory
period of limitations (including extensions) of the Taxable periods to which
such documents relate. Any information obtained pursuant to this Section 11.4
shall be kept confidential, except as may be otherwise necessary in connection
with the filing of Tax Returns or claims for refund or in conducting any audit
or other proceedings.

         11.5  REFUNDS OR CREDITS. Except as otherwise set forth in this
Agreement, to the extent any refunds or credits with respect to Taxes paid by
the Fresh Produce Companies are attributable to any Pre-Closing Tax Period, such
refunds or credits shall be for the account of BHC. Except as provided in the
immediately succeeding sentence, to the extent that any refunds or credits with
respect to Taxes paid by the Fresh Produce Companies are attributable to any
Post-Closing Tax Period, such refunds or credits shall be for the account of
Savia. To the extent that any refunds or credits with respect to taxes paid by
the Fresh Produce Companies are attributable to the Straddle Period described in
Section 11.3, such refunds and credits shall be for the account of the party who
bears responsibility for such Taxes pursuant to Section 11.3. Savia shall cause
the Fresh Produce Companies to forward to BHC or to reimburse BHC for any such
refunds or credits for the account of BHC within 10 business days from receipt
thereof by any of Savia or the Fresh Produce Companies. BHC shall forward to
Savia or reimburse Savia for any refunds or credits for the account of Savia
within 10 business days from receipt thereof by BHC. To the extent any such
refund or credit is properly includable in the taxable income of the initial
recipient, the amount forwarded or reimbursed to BHC or Savia, as the case may
be, shall be reduced by a percentage of the amount of such refund or credit
equal to the highest marginal federal income tax rate for the tax period in
which the refund or credit is received. Any refunds or reimbursements not made
within the 10 business day period specified above shall bear interest from the
date received by the refunding or reimbursing party at the Prime Rate.

         11.6  CONTESTS. In the case of any audit, examination or other
proceeding ("Tax Proceeding") with respect to Taxes for which BHC is or may be
liable pursuant to this Agreement, the general provisions of Section 12.5 shall
apply, in addition to the following specific provisions. Savia shall execute or
cause to be executed powers of attorney or other documents necessary to enable
BHC to take all actions desired by BHC with respect to such Tax Proceeding to
the extent such Tax Proceeding may affect the amount of Taxes for which BHC is
liable pursuant to this Agreement. BHC shall have the right to control any such
Proceedings, and, if there is substantial authority therefor, to initiate any
claim for refund, file any amended return or take any other action which it
deems appropriate with respect to such Taxes. If requested by Savia, BHC shall
provide

                                       35
<PAGE>

to Savia an opinion in form and content reasonably acceptable to Savia from
counsel reasonably acceptable to Savia that there is substantial authority for
the position that BHC is taking with respect to such action, and Savia need not
and BHC shall not take such action until such opinion is delivered to Savia. Any
Tax Proceeding with respect to Taxes for a period which includes but does not
end on the Second Closing Date shall be controlled jointly by BHC and Savia. By
written notice to BHC, Savia shall have the right to instruct BHC to forego
Proceedings with respect to one or more items for which BHC may be liable to
indemnify Savia. Such notice shall constitute a waiver of the right of Savia to
indemnification for any Taxes arising out of such item for the period or periods
involved, but shall not otherwise waive any rights of BHC under this section.

                                   ARTICLE XII

                            SURVIVAL; INDEMNIFICATION

         12.1  SURVIVAL.

         (a)   The representations and warranties of the parties hereto
contained in Articles IV and V of this Agreement or in any certificate,
instrument, or document delivered pursuant hereto shall survive the First
Closing and the Second Closing, regardless of any investigation made by or on
behalf of any party, until the first anniversary of the Second Closing Date
(or the First Closing Date, if the Second Closing does not occur) (the
"Survival Date").

         (b)   The provisions of this Article shall have no effect upon any
other obligation of the parties hereto under this Agreement, whether to be
performed before, at or after the First Closing or Second Closing.

         12.2  INDEMNIFICATION BY BHC.

         (a)   Subject to the terms, limitations and conditions of this Article
XII, BHC shall indemnify, defend and hold harmless Savia and its affiliates and
their respective officers, directors, partners, employees, agents and
representatives from and against any and all claims, actions, causes of action,
demands, assessments, losses, damages, liabilities, judgments, settlements,
penalties, costs and expenses (including reasonable attorneys' fees and
expenses), of any nature whatsoever (each, a "Loss"), asserted against,
resulting to, imposed upon or incurred by Savia or its affiliates or any such
other Person, directly or indirectly, by reason of or resulting from any of the
following:

               (i) all Taxes of the Fresh Produce Companies (and any costs or
         expenses connected therewith) due for any taxable period ending on or
         before December 31, 2000.

         (b)   The indemnification obligations of BHC pursuant to this Article
XII shall be subject to the following limitations and other provisions set forth
herein:

               (i)   No indemnification shall be required to be made by BHC
         with respect to any Losses under this Section 12.2 except to the extent
         that the aggregate amount of such Losses

                                       36
<PAGE>

         incurred by Savia (whether arising, asserted, resulting, imposed or
         incurred before, on or after the Closing Date) exceeds $250,000.

               (ii) No indemnification shall be required to be made by BHC
         with respect to any Losses under Section 12.2 to the extent that the
         aggregate amount of such Losses incurred by Savia (whether arising,
         asserted, resulting, imposed or incurred before, on or after the
         Closing Date) exceeds $5,000,000.

         12.3  INDEMNIFICATION BY SAVIA.

         (a)   Subject to the terms and conditions of this Article XII, Savia
shall indemnify, defend and hold harmless BHC and its affiliates and their
respective officers, directors, partners, employees, agents and representatives
from and against any and all Losses asserted against, resulting to, imposed upon
or incurred by BHC or its affiliates or any such other Person, directly or
indirectly, by reason of or resulting from any of the following:

               (i)   the operation of the business of any Fresh Produce Company,
         whether prior to or from and after the Closing Date, except to the
         extent Savia is indemnified by BHC with respect to such matters
         pursuant to Section 12.2; or

               (ii)  the ownership or use of the DNAP Assets from and after the
         Second Closing Date.

         (b)   The indemnification obligations of Savia pursuant to this Article
XII shall be subject to the following limitations and other provisions set forth
herein:

               (i)   No indemnification shall be required to be made by Savia
         with respect to any Losses under Section 12.3 except to the extent that
         the aggregate amount of such Losses incurred by BHC (whether arising,
         asserted, resulting, imposed or incurred before, on or after the
         Closing Date) exceeds $250,000.

               (ii)  No indemnification shall be required to be made by Savia
         with respect to any Losses under Section 12.3 to the extent that the
         aggregate amount of such Losses incurred by BHC (whether arising,
         asserted, resulting, imposed or incurred before, on or after the
         Closing Date) exceeds $5,000,000.

         12.4  FURTHER LIMITATIONS OF LIABILITY. The amount of any Loss shall be
reduced (i) to the extent that any person entitled to receive indemnification
under this Agreement (an "Indemnitee") receives any insurance proceeds with
respect to a Loss, (ii) to take into account any net Tax benefit recognized by
the Indemnitee arising from the recognition of the Loss and (iii) to take into
account any payment actually received by an Indemnitee with respect to a Loss.

                                       37

         12.5  DEFENSE OF CLAIMS.

         (a) If any Indemnitee receives notice of the assertion of any claim
or of the commencement of any claim, action or proceeding made or brought by
any person or entity who or which is not a party to this Agreement or an
affiliate of a party to this Agreement (a "Third Party Claim") with respect
to which indemnification is to be sought from a person required to provide
indemnification under this Agreement (the "Indemnifying Party"), the
Indemnitee will give such Indemnifying Party reasonably prompt written notice
thereof, but in any event not later than 20 calendar days after the
Indemnitee's receipt of notice of such Third Party Claim, provided the
failure to give timely notice will not affect the rights or obligations of
the Indemnifying Party except and only to the extent that, as a result of
such failure, the Indemnifying Party was substantially disadvantaged. Such
notice shall describe the nature of the Third Party Claim in reasonable
detail and will indicate the estimated amount, if practicable, of the Loss
that has been or may be sustained by the Indemnitee. The Indemnifying Party
will have the right to participate in or, by giving written notice to the
Indemnitee, to elect to assume the defense of any Third Party Claim at such
Indemnifying Party's own expense and by such Indemnifying Party's own
counsel, and the Indemnitee will cooperate in good faith in such defense at
such Indemnitee's own expense.

         (b) If within 10 calendar days after an Indemnitee provides written
notice to the Indemnifying Party of any Third Party Claim, the Indemnitee
receives written notice from the Indemnifying Party that such Indemnifying Party
has elected to assume the defense of such Third Party Claim as provided in the
last sentence of Section 12.5(a), the Indemnifying Party will not be liable for
any legal expenses subsequently incurred by the Indemnitee in connection with
the defense thereof; provided, however, that if the Indemnifying Party fails to
take reasonable steps necessary to defend diligently such Third Party Claim
within 10 calendar days after receiving notice from the Indemnitee that the
Indemnitee believes the Indemnifying Party has failed to take such steps the
Indemnitee may assume its own defense, and the Indemnifying Party will be liable
for all reasonable expenses thereof. Without the prior written consent of the
Indemnitee, the Indemnifying Party will not enter into any settlement of any
Third Party Claim which would lead to liability or create any financial or other
obligation on the part of the Indemnitee for which the Indemnitee is not
entitled to indemnification hereunder. If a firm offer ("Firm Offer") is made to
settle a Third Party Claim without leading to liability or the creation of a
financial or other obligation on the part of the Indemnitee for which the
Indemnitee is not entitled to indemnification hereunder and the Indemnifying
Party desires to accept and agree to such offer, the Indemnifying Party will
give written notice to the Indemnitee to that effect. If the Indemnitee fails to
consent to such firm offer within 10 calendar days after its receipt of such
notice, the Indemnitee may continue to contest or defend such Third Party Claim
and, in such event, the maximum liability of the Indemnifying Party to such
Third Party Claim will be the amount of such Firm Offer, plus reasonable costs
and expenses paid or incurred by the Indemnitee up to the date of such notice.

         (c) Any claim by an Indemnitee on account of a Loss which does not
result from a Third Party Claim (a "Direct Claim") will be asserted by giving
the Indemnifying Party reasonably prompt written notice thereof, stating the
nature of such claim in reasonable detail and indicating the estimated
amount, if practicable, but in any event not later than 20 calendar days
after the Indemnitee becomes aware of such Direct Claim, and the Indemnifying
Party will have a period of 30 calendar

                                       38
<PAGE>

days within which to respond to such Direct Claim. If the Indemnifying Party
does not respond within such 30 day period, the Indemnifying Party will be
deemed to have accepted such claim. If the Indemnifying Party rejects such
claim, the Indemnitee will be free to seek enforcement of its rights to
indemnification under this Agreement.

         (d) If the amount of any Loss, at any time subsequent to the making
of an indemnity payment in respect thereof, is reduced by recovery,
settlement or otherwise under or pursuant to any insurance coverage or Tax
benefit, or pursuant to any claim, recovery, settlement or payment by or
against any other entity, the amount of such reduction, less any costs,
expenses or premiums incurred in connection therewith, will promptly be
repaid by the Indemnitee to the Indemnifying Party. Upon making any indemnity
payment, the Indemnifying Party will, to the extent of such indemnity
payment, be subrogated to all rights of the Indemnitee against any third
party in respect of the Loss to which the indemnity payment relates;
provided, however, that (i) the Indemnifying Party will then be in compliance
with its obligations under this Agreement in respect of such Loss, and (ii)
until the Indemnitee recovers full payment of its Loss, any and all claims of
the Indemnifying Party against any such third party on account of said
indemnity payment are hereby made expressly subordinated and subjected in
right of payment to the Indemnitee's rights against such third party. Without
limiting the generality or effect of any other provision hereof, each such
Indemnitee and Indemnifying Party will duly execute upon request all
instruments reasonably necessary to evidence and perfect the above-described
subrogation and subordination rights. Nothing in this Section 12.5(d) shall
be construed to require any party hereto to obtain or maintain any insurance
coverage.

         (e) In addition to the foregoing, Section 11.7 shall also apply with
respect to Tax Proceedings.

         12.6  TAX TREATMENT OF INDEMNITY PAYMENTS. Each of the parties
agrees to treat any payments made pursuant to this Article XII, under any
other indemnity provision in this Agreement and for any misrepresentations or
breach of warranties or covenants as adjustments to the Purchase Price for
all federal and state income tax purposes.

         13.2  ENTIRE AGREEMENT. This Agreement, together with the Exhibits,
Schedules and other writings referred to herein or delivered pursuant hereto,
including the Cash Support Agreement, constitute the entire agreement among the
parties hereto with respect to the subject matter hereof and supersede all prior
agreements and understandings, both written and oral, among the parties with
respect to the subject matter hereof.

         13.3  BINDING EFFECT; ASSIGNMENT; NO THIRD PARTY BENEFIT. This
Agreement shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and permitted assigns. Except as
otherwise expressly provided in this Agreement, neither this Agreement nor
any of the rights, interests, or obligations hereunder shall be assigned by
any of the parties hereto without the prior written consent of the other
parties. In connection with the First Closing or Second Closing, Savia may
assign its rights under this Agreement to one or more of its affiliates (as
defined in Rule 405 under the Securities Act) if such affiliate shall have
furnished BHC with the representations contained in Sections 5.5 through 5.8
and Section 7.13 of this Agreement and shall have agreed with BHC to be
subject to the terms of this Agreement to the same extent as if an original
purchaser pursuant hereto. Except as expressly provided herein, nothing in
this Agreement, express or implied, is intended to or shall confer upon any
person other than the parties hereto, and their respective successors and
permitted assigns, any rights, benefits, or remedies of any nature whatsoever
under or by reason of this Agreement.

         13.4  SEVERABILITY. If any provision of this Agreement is held to be
unenforceable, this Agreement shall be considered divisible and such provision
shall be deemed inoperative to the extent it is deemed unenforceable, and in all
other respects this Agreement shall remain in full force and effect; provided,
however, that if any such provision may be made enforceable by limitation
thereof, then such provision shall be deemed to be so limited and shall be
enforceable to the maximum extent permitted by Applicable Law.

         13.5  GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE,
WITHOUT REGARD TO THE PRINCIPLES OF CONFLICTS OF LAWS THEREOF.

         13.6  FURTHER ASSURANCES. From time to time following the consummation
of any of the transactions contemplated hereby, at the request of any party
hereto and without further consideration, the other party or parties hereto
shall execute and deliver to such requesting party such instruments and
documents and take such other action (but without incurring any material
financial obligation) as such requesting party may reasonably request in order
to consummate more fully and effectively the transactions contemplated hereby.

         13.7  DESCRIPTIVE HEADINGS. The descriptive headings herein are
inserted for convenience of reference only, do not constitute a part of this
Agreement, and shall not affect in any manner the meaning or interpretation of
this Agreement.

         13.8  GENDER. Pronouns in masculine, feminine, and neuter genders shall
be construed to include any other gender, and words in the singular form shall
be construed to include the plural and vice versa, unless the context otherwise
requires.

         13.9  [Intentionally omitted.]

         13.10 COUNTERPARTS. This Agreement may be executed by the parties
hereto in any number of counterparts, each of which shall be deemed an original,
but all of which shall constitute one and the same agreement. Each counterpart
may consist of a number of copies hereof each signed by less than all, but
together signed by all, the parties hereto.

         13.11 INJUNCTIVE RELIEF. The parties hereto acknowledge and agree that
irreparable damage would occur in the event any of the provisions of this
Agreement were not performed in accordance with their specific terms or were
