and effective as of April 1, 2001, by and between BUNGE INTERNATIONAL LIMITED, a
company organized with limited liability under the laws of Bermuda ("DEBTOR"),
and BUNGE LIMITED, a company organized with limited liability under the laws of
Bermuda (the "SECURED PARTY").

                              W I T N E S S E T H:
                              - - - - - - - - - -

            WHEREAS, Debtor and the Secured Party have entered into an agreement
dated as of May 17, 2001, and effective as of April 1, 2001 (the "LOAN
AGREEMENT"), pursuant to which certain Advances (as defined in the Loan
Agreement) made by the Secured Party to Debtor shall be governed; and

            WHEREAS, in order to induce the Secured Party to enter into the Loan
Agreement and to maintain the Advances, Debtor has agreed to grant security
interests in certain property as contemplated by this Agreement.

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

      SECTION 1. GRANTING CLAUSE.

      Debtor hereby irrevocably pledges, transfers and assigns to the Secured

right, title and interest of Debtor in, to and under the following
(collectively, the "COLLATERAL"):

      (a) 12,000 (Twelve Thousand) shares of common stock, par value U.S. $1.00
(One Dollar) per share, of Bunge Foods Limited (the "SHARES");

receivable or otherwise distributed or distributable in respect of or in
exchange for any or all of the Shares.

      SECTION 2. SECURITY FOR OBLIGATIONS.

            This Agreement secures, and the Collateral is security for, the

the Note (as defined in the Loan Agreement) and all obligations of Debtor now or
hereafter existing under this Agreement (all such obligations of Debtor being
referred to herein as the "SECURED OBLIGATIONS").

      SECTION 3. DELIVERY OF COLLATERAL.

            All certificates or instruments representing or evidencing the
Collateral shall be delivered to and held by or on behalf of the Secured Party
pursuant hereto and shall be in suitable form for transfer by delivery, or shall
be accompanied by duly executed instruments of transfer or assignment in blank,
all in form and substance satisfactory to the Secured Party in its sole
judgment. In addition, the Secured Party shall have the right at any time to
exchange certificates or instruments representing or evidencing the Collateral
for certificates or instruments of smaller or larger denominations.

      SECTION 4. REPRESENTATIONS AND WARRANTIES.

      (a) Debtor represents and warrants as follows:

            (i) Debtor is the direct and beneficial owner of the Collateral free
and clear of any lien or encumbrance other than the lien granted to the Secured
Party hereunder.

            (ii) Debtor has full power, authority and legal right to pledge,
transfer and assign the Collateral to the Secured Party as provided herein.

            (iii) This Agreement has been duly authorized, executed and
delivered by Debtor and constitutes the legal, valid and binding obligations of
Debtor, enforceable against Debtor in accordance with its terms, subject, as to
enforcement, to applicable bankruptcy, insolvency, or other similar laws
affecting creditors' rights and remedies generally or by the application of
general principles of equity.

            (iv) The pledge of the Shares pursuant to this Agreement creates a
valid and perfected security interest in the Shares.

            (v) No consent, authorization, approval, or other action by, and no
notice to or filing with, any governmental authority or regulatory body is
required either (A) for the grant of the security interest in the Collateral by
Debtor pursuant to this Agreement or for the execution, delivery or performance
of this Agreement by Debtor or (B) for the exercise by the Secured Party of the
voting or other rights provided for in this Agreement or the remedies in respect
of the Collateral pursuant to this Agreement, except as may be required in
connection with the disposition of the Collateral by laws affecting the offering
and sale of securities generally.

      (b) The representations and warranties set forth in this Section 4 shall
survive the execution and delivery of this Agreement.

      SECTION 5. FURTHER ASSURANCES; REGISTER OF CHARGES.

      (a) Debtor agrees that at any time and from time to time, at the expense
of Debtor, Debtor will promptly execute and deliver or file all further
instruments and documents (including without limitation financing statements on
Form UCC-1), and take all further action that may be necessary or desirable, or
that the Secured Party may request, in order to perfect and protect any security
interest granted or purported to be granted hereby or to enable the Secured
Party to exercise and enforce its rights and remedies hereunder with respect to
any Collateral.

                                       2
<Page>

      (b) Debtor will defend the Secured Party's right, title, and security
interest in and to the Collateral and the liens of the Secured Party thereon
against the claim of any person and will maintain and preserve such liens so
long as any Secured Obligations are outstanding.

      (c) If Debtor shall become entitled to receive or shall receive any
certificate or other instrument (including, without limitation, any certificate
representing a stock dividend or distribution in connection with any
reclassification, increase or reduction in capital), option or right, whether in
addition to, in substitution of, or in exchange for any of the Collateral,
Debtor shall accept any such certificate or other instrument as the Secured
Party's agent, shall hold such instrument in trust for the Secured Party, and
shall deliver such instrument forthwith to the Secured Party in the exact form
received, with Debtor's endorsement when necessary and/or appropriate stock
powers and other instruments of transfer which may be necessary or desirable
duly executed in blank, to be held by the Secured Party, subject to the terms
hereof, as further collateral for the Secured Obligations and the same shall for
all purposes be deemed to be Collateral hereunder.

      (d) The Debtor shall cause brief particulars of the security interest
granted hereby to be registered with the Register of Charges in accordance with
Section 55 of the Companies Act 1981 of Bermuda promptly upon execution and
delivery hereof.

      SECTION 6. VOTING RIGHTS; DIVIDENDS; ETC.

      (a) As long as no Breach shall have occurred (for purposes hereof, the
term "Breach" shall mean (i) a default by Debtor in the performance of any
covenant contained in the Loan Agreement or (ii) a breach of any representation
or warranty made by Debtor in the Loan Agreement, in either case if and only to
the extent that Debtor is liable therefor and has not discharged such liability
under the terms of the Loan Agreement, or (iii) a default or proven breach by
Debtor under the terms of this Agreement) Debtor shall be entitled to exercise
any and all voting and other consensual rights, pertaining to the Collateral or
any part thereof for any purpose not inconsistent with the terms of this
Agreement or the Loan Agreement; PROVIDED, HOWEVER, that Debtor shall not
exercise or refrain from exercising any such right if such action or inaction
would have a material adverse effect on the value of the Collateral or any part
thereof.

      (b) Upon the occurrence and during the continuance of a Breach all of
Debtor's rights to exercise the voting and other consensual rights which it
would otherwise be entitled to exercise pursuant to Section 6(a) above shall
cease upon notice from the Secured Party to Debtor, and all such rights shall
thereupon become vested in the Secured Party which shall thereupon have the sole
right to exercise such voting and other consensual rights and any and all rights
of conversion, exchange, subscription or any other rights, privileges or options
pertaining to the Collateral or any part thereof, and the Secured Party may
exercise such powers in such manner as the Secured Party may elect, but the
Secured Party shall have no duty to exercise any of the aforesaid rights,
privileges or options and shall not be responsible for any failure to do so or
delay in doing so.

      (c) In order to permit the Secured Party to exercise the voting and other
rights which it may be entitled to exercise pursuant to Section 6(a), Debtor
shall, if necessary, upon written notice of the Secured Party, from time to time
execute and deliver to the Secured Party

                                       3
<Page>

appropriate proxies, dividend payment orders, assignments and other instruments
as the Secured Party may reasonably request including, without limitation, the
irrevocable proxy in the form of Exhibit A hereto delivered by Debtor to the
Secured Party on the date hereof.

      SECTION 7. TRANSFERS AND OTHER LIENS; ADDITIONAL SHARES OR WARRANTS

      Except as contemplated by the Loan Agreement, Debtor agrees that it will
not (i) sell, assign or transfer or otherwise dispose of, or grant any option,
warrant, subscription, call, or other agreement with respect to, any of the
Collateral, or (ii) create or permit to exist any lien, security interest, or
other charge or encumbrance upon or with respect to any of the Collateral,
except for the lien in favor of the Secured Party under this Agreement.

      SECTION 8. SECURED PARTY MAY PERFORM.

      If Debtor fails to perform any agreement contained herein, the Secured
Party may itself perform, or cause performance of, such agreement, and the
expenses of the Secured Party incurred in connection therewith shall be payable
by the Debtor.

      SECTION 9. REASONABLE CARE.

      The Secured Party shall be deemed to have exercised reasonable care in the
custody and preservation of the Collateral in its possession if the Collateral
is accorded treatment substantially equal to that which the Secured Party
accords its own property, it being understood that the Secured Party shall not
have any responsibility for (i) ascertaining or taking action with respect to
calls, conversions, exchanges, maturities, tenders or other matters relative to
any Collateral, whether or not the Secured Party has or is deemed to have
knowledge of such matters, or (ii) taking any necessary steps to preserve rights
against any parties with respect to any Collateral.

      SECTION 10. REMEDIES UPON BREACH.

      If any Breach shall have occurred and be continuing:

      (a) The Secured Party may exercise in respect of the Collateral, in
addition to other rights and remedies provided for herein or otherwise available
to it, all the rights and remedies of a secured party under the Uniform
Commercial Code in effect in New York, and the Secured Party may also, without
notice except as specified below, sell the Collateral or any part thereof in one
or more parcels at public or private sale, at any exchange, broker's board or at
any of the Secured Party's offices or elsewhere, for cash, on credit or for
future delivery, and upon such other terms as the Secured Party may deem
commercially reasonable and the Secured Party may be the purchaser of any or all
of the Collateral so sold. Each purchaser at any such sale, including, without
limitation, the Secured Party, shall hold the property sold absolutely, free and
clear from any claim or right of redemption of Debtor, and Debtor specifically
waives all rights of redemption, stay or appraisal which it has or may have
under any rule or law or statute now existing or hereafter adopted. Debtor
agrees that, to the extent notice of sale shall be required by law, at least ten
(10) days' notice to Debtor of the time and place of any public sale or the time
after which any private sale is to be made shall constitute reasonable
notification. The Secured Party shall not be obligated to make any sale of
Collateral regardless of notice of sale having

                                       4
<Page>

been given. The Secured Party may adjourn any public or private sale from time
to time by announcement at the time and place fixed therefor, and such sale may,
without further notice, be made at the time and place to which it was so
adjourned. The Debtor hereby waives any claims against the Secured Party arising
by reason of the fact that the price at which any Collateral may have been sold
at such a private sale was less than the price which might have been obtained at
a public sale, even if the Secured Party accepts the first offer received and
does not offer such Collateral to more than one offeree. In addition, the
Secured Party shall have the right to register, or cause to be registered any or
all of the Collateral in the name of the Secured Party or its nominee.
Notwithstanding anything in this Section 10(a) to the contrary, the Secured
Party will use reasonable commercial efforts to sell, or will register or cause
to be registered in its own name, only that portion of the Collateral as is
necessary to satisfy the aggregate liability of the Debtor resulting from such
Breach.

      (b)   Debtor recognizes that, by reason of certain requirements and
prohibitions contained in the Securities Act of 1933, as amended (the
"SECURITIES ACT"), and applicable state securities laws, the Secured Party may
with respect to any sale of all or any part of the Collateral, limit purchasers
to those who will agree, among other things, to acquire such securities for
their own account, for investment, and not with a view to the distribution or
resale thereof. Debtor acknowledges and agrees that any such sale may result in
prices and other terms less favorable to the seller than if such sale were a
public sale without such restrictions and, notwithstanding such circumstances,
agrees that any such sale shall be deemed to have been made in a commercially
reasonable manner. The Secured Party shall be under no obligation to delay the
sale of any of the Shares for the period of time necessary to permit Debtor to
register such securities for public sale under the Securities Act, or under
applicable state securities laws, even if Debtor would agree to do so.

      (c)   If the Secured Party determines to exercise its right to sell any or
all of the Collateral, upon written request, Debtor shall, from time to time,
furnish to the Secured Party all such information as the Secured Party may
request in order to determine the number of shares and other instruments
included in the Collateral which may be sold by the Secured Party as exempt
transactions under the Securities Act and rules of the Securities and Exchange
Commission thereunder, as the same are from time to time in effect.

      (d)   Any cash held by the Secured Party as Collateral and all cash
proceeds received by the Secured Party in respect of any sale of, collection
from, or other realization upon all or any part of the Collateral shall be
applied by the Secured Party:

            First, to the payment of the costs and expenses of such sale,
including reasonable compensation to the Secured Party and its agents and
counsel, and all expenses, liabilities and advances made or incurred by the
Secured Party in connection therewith;

            Second, to the Secured Party on account of the Secured Obligations
in such order as the Secured Party may elect; and

            Third, after indefeasible payment in full of all Secured
Obligations, to the Debtor, or its successors and assigns, or to whomsoever may
be lawfully entitled to receive the same or

                                       5
<Page>

as a court of competent jurisdiction may direct, of any surplus then remaining
from such proceeds.

      SECTION 11. SECURITY INTEREST ABSOLUTE.

      All rights of the Secured Party and security interests hereunder, and all
obligations of Debtor hereunder, shall be absolute and unconditional
irrespective of: (a) any lack of validity or enforceability of the Loan
Agreement or any other document, agreement or instrument relating thereto;

      (b) any change in the time, manner or place of payment of, or in any other
term of, all or any of the Secured Obligations, or any other amendment or waiver
of or any consent to any departure from the Loan Agreement or any other
document, agreement or instrument relating thereto;

      (c) any exchange, release or nonperfection of any other collateral for all
or any of the Secured Obligations; or

      (d) any other circumstance which might otherwise constitute a defense
available to, or a discharge of, Debtor or a third party granting a security
interest.

      SECTION 12. WAIVER.

      No delay on the Secured Party's part in exercising any power of sale,
lien, option or other right hereunder, and no notice or demand which may be
given to or made upon Debtor by the Secured Party with respect to any power of
sale, lien, option or other right hereunder, shall constitute a waiver thereof,
or limit or impair the Secured Party's right to take any action or to exercise
any power of sale, lien, option, or any other right hereunder, without notice or
demand, or prejudice the Secured Party's rights hereunder or the rights of the
Secured Party under the Loan Agreement or any other document agreement or
instrument relating thereto as against Debtor in any respect.

      SECTION 13. AMENDMENTS, ETC.

      No amendment or waiver of any provision of this Agreement, nor consent to
any departure by Debtor herefrom, shall in any event be effective unless the
same shall be in writing and signed by the Secured Party, and then such waiver
or consent shall be effective only in the specific instance and for the specific
purpose for which given.

      SECTION 14. ADDRESSES FOR NOTICES.

      All notices and other communications provided for hereunder shall be given
and deemed to be delivered and effective as provided in Section 6.2 of the Loan
Agreement.

      SECTION 15. CONTINUING SECURITY INTEREST.

      This Agreement shall create a continuing first priority security interest
in the Collateral, and shall (a) remain in full force and effect until
indefeasible payment in full of the Secured

                                       6
<Page>

Obligations; (b) continue to be effective or be reinstated, as the case may be,
if at any time payment and performance of the Secured Obligations, or any part
thereof, is, pursuant to applicable law, rescinded or reduced in amount, or must
otherwise be restored or returned by the obligee of the Secured Obligations, all
as though such payment or performance had not been made; (c) be binding upon
Debtor, its successors, or assigns; and (d) inure to the benefit of the Secured
Party and its successors, transferees and assigns.

      SECTION 16. RELEASE OF COLLATERAL.

      Upon the payment in full of the Secured Obligations, the Debtor shall be
entitled to the return, upon its request and at its expense, of such of the
Collateral as shall not have been sold or otherwise applied pursuant to the
terms hereof.

      SECTION 17. SEVERABILITY.

      If for any reason any provision or provisions hereof are determined to be
invalid and contrary to any existing or future law, such invalidity shall not
impair the operation of or effect those portions of this Agreement which are
valid.

      SECTION 18. SECTION TITLES.

      The Section titles contained in this Agreement are and shall be without
substantive meaning or content of any kind whatsoever and are not a part of the
agreement between the parties hereto.

      SECTION 19. WAIVER OF JURY TRIAL.

      DEBTOR AND THE SECURED PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE
TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT AND
FOR ANY COUNTERCLAIM THEREIN.

      SECTION 20. GOVERNING LAW; TERMS.

      THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS
AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE
WITH, THE LAW OF THE STATE OF NEW YORK. Unless otherwise defined herein or in
the Loan Agreement, terms defined in Articles 8 and 9 of the UCC are used herein
as therein defined. In the event of any inconsistency between the terms of the
Loan Agreement and this Agreement, the terms of the Loan Agreement shall
control.

      SECTION 21. POWER OF ATTORNEY.

      Debtor hereby authorizes the Secured Party and does hereby make,
constitute and appoint the Secured Party and any officer of agent of the Secured
Party, with full power of substitution, as Debtor's true and lawful

receipt for, comprise, settle and sue for monies due in respect of the
Collateral; and generally, to do, at Secured Party's option at the Debtor's
expense, at any time, or from time to time, all acts and things which the

Collateral and Secured Party's security interest therein in order to effect the
intent of this Agreement all as fully and effectually as Debtor might or would
do; and Debtor hereby ratifies all that said attorney shall lawfully do or cause
to be done by virtue hereof. This power of attorney shall be irrevocable for the
term of this Agreement and thereafter as long as any of the Secured Obligations

The Reorganized Company is a corporation duly organized and in good standing
under the laws of the state of Delaware and is duly qualified as a foreign
corporation and in good standing in all states or other jurisdictions where the
nature and extent of the business transacted by it or the ownership of assets
makes such qualification necessary, except for those jurisdictions in which the
failure to so qualify has not had and could not reasonably be expected to have a
Material Adverse Effect. After giving effect to the Confirmation Order, the
execution, delivery and performance of this Agreement, the Registration Rights
Agreement and the transactions contemplated hereunder and thereunder are all
within the Reorganized Company's corporate powers, have been duly authorized and
are not in contravention of law or the terms of the Reorganized Company's
certificate of incorporation, by-laws, or other organizational documentation, or
any indenture, agreement or undertaking to which the Reorganized Company is a
party or by which the Reorganized Company or its property is bound. After giving
effect to the Confirmation Order, this Agreement and the Registration Rights
Agreement constitute legal, valid and binding obligations of the Reorganized
Company enforceable in accordance with their respective terms. The Reorganized
Company has no Subsidiaries.

hereto no class of capital stock of the Reorganized Company is entitled to
preemptive rights. Except as set forth on Schedule 2.2 hereto, there are no
outstanding options, warrants, subscription rights, calls or commitments of any
character whatsoever relating to, or securities or rights convertible into,
shares of any class of capital stock of the Reorganized Company, or agreements,
by which the Reorganized Company is or may become bound to issue additional
shares of its capital stock or options, warrants or other rights to purchase or
acquire any shares of its capital stock. Except as set forth on Schedule 2.2
hereto, no warrants, bonds, debentures, notes or other indebtedness or other

Schedule 2.2 hereto or as contemplated by the Transaction Documents, the
Reorganized Company is not a party to, and, to the Reorganized Company's best

first refusal, right of first offer, proxy, voting agreement, voting trust,
registration rights agreement, shareholders' agreement, etc., whether or not the
Reorganized Company is a party thereto) with respect to the purchase, sale or
voting of any shares of capital stock of the Reorganized Company (whether

provision of law, its certificate of incorporation or by-laws, any agreement or
otherwise. Except as set forth on Schedule 2.2 hereto or as contemplated by the

directors of the Reorganized Company. Immediately following the transactions
contemplated hereby, the Reorganized Company's capitalization will be as set
forth on Schedule 2.2 hereto. The Reorganized Company has not declared or paid

best of the Reorganized Company's knowledge threatened, against or affecting the
Reorganized Company, its assets or business and there is no action, suit,
proceeding or claim by any Person pending, or to the best of the Reorganized
Company's knowledge threatened, against or affecting the Reorganized Company or
its assets or goodwill, or against or affecting any transactions contemplated by
the Transaction Documents, which has resulted, or if adversely determined
against the Reorganized Company could reasonably be expected to result, in any
Material Adverse Effect.

in default under, or in violation of any of the terms of, any agreement,

Authority or any other person nor is any pending, or to the best of the

of the Reorganized Company except to the extent the Reorganized Company is
materially prejudiced thereby. With respect to each third-party claim subject to
this Section 3 (a "Third-Party Claim"), the Reorganized Company, at its sole
cost and expense, may, upon notice to the Indemnified Party within fifteen (15)
days after the Reorganized Company receives notice of the Third-Party Claim,
assume the defense of the Third-Party Claim. The Reorganized Company shall not
consent to a settlement of, or the entry of any judgment arising from, any
Third-Party Claim, unless the Indemnified Party consents thereto, which consent
shall not be unreasonably withheld. The Indemnified Party shall be entitled to
participate in the defense of any Third-Party Claim, the defense of which is
assumed by the Reorganized Company, with its own counsel and at its own expense.
The parties shall cooperate in the defense of any Third-Party Claim and the

Purchasers, and their respective successors and assigns, and the Reorganized
Company may take any action herein prohibited, or omit to perform any act

the party or parties against whom enforcement of any waiver, change,
modification or discharge is sought or by parties with the right to consent to
such waiver, change, modification or discharge on behalf of such party.

                  5.7 Successors and Assigns. All covenants and agreements
contained herein shall bind and inure to the benefit of the parties hereto and
their respective successors and assigns. Notwithstanding the foregoing, this
Agreement shall not be assignable by either party hereto (other than by
operation of law) without the prior written consent of the other party hereto;
provided, that a Purchaser may assign its rights and obligations hereunder to
any other Purchaser or to a purchaser of shares of Common Stock held by it.

                  5.8 Expenses. The Reorganized Company agrees to pay to each
Purchaser all reasonable costs and expenses incurred by such Purchaser relating
to any future amendment or supplement to any of the Transaction Documents (or
any proposal by the Reorganized Company for such amendment or supplement)
whether or not consummated or any waiver or consent with

<PAGE>   16
respect thereto (or any proposal for such waiver or consent) whether or not
consummated, and all costs and expenses of such Purchaser relating to the
enforcement of any of the Transaction Documents.

                  5.9 Transfer of Common Stock. Each Purchaser understands and
agrees that each Share or certificate representing the Shares shall bear the
following legend:

                  THESE SHARES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
                  OF 1933 OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE
                  SOLD OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE
                  REGISTRATION STATEMENT UNDER SUCH ACT AND APPLICABLE STATE
                  SECURITIES LAWS OR AN APPLICABLE EXEMPTION TO THE REGISTRATION
                  REQUIREMENTS OF SUCH ACT OR SUCH LAWS.

                  The requirement that the foregoing legend be placed upon
certificates evidencing any such Shares, shall cease and terminate upon the
earliest of the following events: (i) when such Shares are transferred in a
public offering under the Securities Act, (ii) when such Shares are transferred
pursuant to Rule 144 under the Securities Act, or (iii) when such Shares are
transferred in any other transaction, if the Purchaser delivers to the
Reorganized Company an opinion of its counsel, which counsel and opinion shall
be reasonably satisfactory to the Reorganized Company; or a "no-action" letter
from the staff of the Securities Exchange Commission; in either case, to the
effect that such legend is no longer necessary in order to protect the
Reorganized Company against a violation by it of the Securities Act upon any
sale or other disposition of such Shares without registration thereunder. Upon
the occurrence of any event, requiring the removal of legend hereunder, the
Reorganized Company, upon the surrender of certificates containing such legend,
shall, at its own expense, deliver to the holder of any such Shares as to which
the requirement for such legend shall have terminated, one or more new
certificates evidencing such Shares not bearing such legend.

ENFORCED IN ACCORDANCE WITH, AND THE RIGHTS OF THE PARTIES SHALL BE GOVERNED BY,
THE LAW OF THE STATE OF NEW YORK EXCLUDING CHOICE-OF-LAW PRINCIPLES OF THE LAW
OF SUCH STATE THAT WOULD REQUIRE THE APPLICATION OF THE LAWS OF A JURISDICTION
OTHER THAN SUCH STATE.

                  5.11 Submission to Jurisdiction. If any litigation shall be
brought by any Purchaser in order to enforce any right or remedy under this
Agreement, the Reorganized Company hereby consents and will submit, and will
cause each of its Subsidiaries to submit, to the jurisdiction of any state or
federal court of competent jurisdiction sitting within the area comprising the
Southern District of New York on the date of this Agreement. The Reorganized
Company hereby irrevocably waives any objection, including, but not limited to,

conveniens, which it may now or hereafter have to the bringing of any such
litigation in such jurisdiction.
<PAGE>   17
                  5.12 Service of Process. Nothing herein shall affect the right
of any Purchaser to serve process in any other manner permitted by law or to
commence legal proceedings or otherwise proceed against the Reorganized Company
in any other jurisdiction.

                  5.13 Waiver of Jury Trial. The Reorganized Company hereby
waives any right it may have to a trial by jury in respect of any action,
proceeding or litigation directly or indirectly arising out of, under or in
connection with, this Agreement.

                  5.14 Signatures. This Agreement shall be effective upon
delivery of original signature pages or facsimile copies thereof executed by
each of the parties hereto.

                  5.15 Further Assurances. Each party hereto agrees that it
shall, at the Reorganized Company's expense and upon the reasonable request of
the other party, duly execute and deliver, or cause to be duly executed and
delivered, to the other party such further instruments, agreements and documents
