                  NOW, THEREFORE, in consideration of the premises and the
mutual covenants herein contained and intending to be legally bound hereby,
the parties hereto agree as follows:

                  Section 1. Each capitalized term used in this Protocol
Agreement and not otherwise defined herein shall have the meaning ascribed
thereto in the Amended Distribution Agreement.

                  Section 2. This Protocol Agreement is a written, signed
amendment and modification of (i) the Amended Distribution Agreement, in
satisfaction of the requirements of Section 10.06 of the Amended
Distribution Agreement and (ii) only in the event that it is approved by the
Monsanto Special Committee as contemplated in Section 7 below, the Amended
Separation Agreement (as defined below), in satisfaction of the requirements
of Section 11.07 of the Amended Separation Agreement.

                  Section 3. In the event that Solutia does not, within
5 days of any judgment, post a bond sufficient to stay the execution of any
judgment rendered in the Litigation pending any Appeal, Pharmacia shall post
such bond, provided that Pharmacia is able to obtain a bond upon
commercially reasonable terms for a company of Pharmacia's financial
conditions and resources and provided further that, as conditions precedent:
(i) Solutia and New Monsanto each promptly and fully perform all duties,
fulfill all obligations and meet all requirements set forth herein; and
(ii) Solutia successfully completes the issuance and sale of Senior Secured
Notes (the "Senior Notes") contemplated in Solutia's Preliminary Offering
            ------------
Memorandum dated June 18, 2002 ("POM"); and (iii) Solutia completes its
                                 ---
refinancing plan and the proceeds from the sale of the Senior Notes that
will be held in escrow by SOI Funding Corp. shall have been released to
Solutia (other than in connection with any redemption of the Senior Notes)
as part of Solutia's refinancing plan all upon such terms and conditions
substantially as described in the POM and in all material respects as
described in the Final Offering Memorandum relating to the Senior Notes.

                  Section 4. Solutia shall provide immediate notice of (and
in no event more than three business days after) any judgment in the
Litigation that may be appealed or that may give rise to a right by a party
to the Litigation to enforce such judgment against Solutia, Pharmacia or any
other person or to execute such judgment against any asset of Solutia,
Pharmacia or any other person.

                  Section 5. In the event Pharmacia posts a bond pursuant to
Section 3 above, and subject to Section 7 below, the following shall apply:

                           (a) Solutia shall reimburse or pay directly, and
in no event later than thirty (30) days after receipt of an invoice or bill,
Pharmacia's and/or New Monsanto's Expenses (as defined hereinafter).
"Expenses" means all of Pharmacia's and/or new Monsanto's out-of-pocket
 --------
expenses in connection with obtaining any bond that are incurred no earlier
than forty-five (45) days before the bond is posted, including, without
limitation: (i) the premium due on the bond and/or the fees charged by the
provider of any bond; (ii) the fees and expenses relating to any third-party
credit enhancement related to the bond; (iii) all costs and expenses of
securing Pharmacia's and/or New Monsanto's obligations with respect to the
bond; and (iv) fees and expenses of financial advisors and attorneys
retained by Pharmacia or New Monsanto in


                                     3

<PAGE>
<PAGE>

connection with the foregoing. To the extent Solutia does not reimburse or
pay directly Pharmacia's Expenses in accordance with this Section 5(a), New
Monsanto shall reimburse or pay directly Pharmacia's Expenses within thirty
(30) days after the written notice of Solutia's failure to reimburse or pay
such expenses.

                           (b) (i) If, pursuant to Section 3 above,
Pharmacia is able to obtain a bond sufficient to stay the execution of any
judgment rendered in the Litigation pending an Appeal without providing or
posting any collateral or third-party credit enhancement ("Collateral"),
then Solutia, New Monsanto and Pharmacia shall have shared control over
decisions to compromise or settle any and all claims at issue, or arguably
at issue, in any Appeal and/or the Litigation. If under this provision
Solutia, New Monsanto and Pharmacia are unable to unanimously agree with
respect to any decision concerning the compromise or settlement of any claim
at issue, or arguably at issue, in any Appeal and/or the Litigation, then
the agreement of any two of the three parties hereto shall be binding upon
all parties hereto. If, pursuant to Section 3 above, Pharmacia is unable to
obtain a bond sufficient to stay the execution of any judgment rendered in
the Litigation pending an Appeal without providing Collateral, then control
over decisions to compromise or settle any and all claims at issue, or
arguably at issue, in any Appeal and/or the Litigation shall be determined
pursuant to Sections 5(b)(ii)-(iv) below.

                               (ii) If, pursuant to Section 3 above,
Pharmacia is unable to obtain a bond sufficient to stay the execution of any
judgment rendered in the Litigation pending an Appeal without providing
Collateral, then Solutia shall have the first option to provide all
Collateral necessary to obtain the bond as contemplated by Section 3 above.
If Solutia exercises this option and provides all Collateral necessary for
Pharmacia to post the bond, then Solutia shall have sole and exclusive right
to compromise or settle on a commercially reasonable basis all claims at
issue, or arguably at issue, in any Appeal and/or the Litigation and Solutia
need not receive the consent or approval of Pharmacia or New Monsanto to
settle all of the claims at issue, or arguably at issue, in any Appeal
and/or the Litigation, provided that the settlement includes as a term
thereof the delivery by the claimant(s) or plaintiff(s) to Pharmacia of a
written release of Pharmacia, New Monsanto and Solutia from all liability in
respect to the Litigation once payment of the settlement and fulfillment of
any other obligations of the settlement have been effectuated. Solutia shall
nevertheless have a duty of prior consultation with New Monsanto and
Pharmacia concerning any settlement decision as set forth in Section 6
below.

                               (iii) If, pursuant to Section 3 above,
Pharmacia is unable to obtain a bond sufficient to stay the execution of any
judgment rendered in the Litigation pending an Appeal without providing
Collateral and Solutia does not exercise (or fails to exercise within five
(5) business days after receiving a written request from Pharmacia) its
first option as set forth in Section 5(b)(ii) above, then New Monsanto shall
have the second option to provide all Collateral necessary to obtain the
bond as contemplated by Section 3 above. If New Monsanto exercises this
option and provides all Collateral necessary for Pharmacia to post the bond,
then New Monsanto shall have sole and exclusive right to compromise or
settle on a commercially reasonable basis all claims at issue, or arguably
at issue, in any Appeal and/or the Litigation and New Monsanto need not
receive the consent or approval of Pharmacia or Solutia to settle all of the
claims at issue, or arguably at issue, in any Appeal and/or the Litigation,
provided that the settlement includes as a term thereof the delivery by the
claimant(s) or plaintiff(s) to Pharmacia and Solutia of a written release of
Pharmacia, New Monsanto and Solutia from all liability in


                                     4

<PAGE>
<PAGE>

respect to the Litigation once payment of the settlement and fulfillment of
any other obligations of the settlement have been effectuated. New Monsanto
shall nevertheless have a duty of prior consultation with Solutia and
Pharmacia concerning any settlement strategies or decision as set forth in
Section 6 below.

                               (iv) If, pursuant to Section 3 above,
Pharmacia is unable to obtain a bond sufficient to stay the execution of any
judgment rendered in the Litigation pending an Appeal without providing
Collateral and neither Solutia nor Monsanto exercises (or if both fail to
exercise their respective options within five (5) business days after
receiving a written request from Pharmacia) its option as set forth in
Section 5(b)(ii) and (iii) above, then Pharmacia shall provide the
Collateral necessary to obtain the bond as contemplated by Section 3 above.
In such case, Pharmacia shall have sole and exclusive right to compromise or
settle on a commercially reasonable basis any and all claims at issue, or
arguably at issue, in any Appeal and/or the Litigation and need not receive
the consent or approval of Solutia or New Monsanto to settle all or some of
the claims at issue, or arguably at issue, in any Appeal and/or the
Litigation, provided that the settlement includes as a term thereof delivery
by the claimant(s) or plaintiff(s) to Solutia and New Monsanto of a written
release of Pharmacia, New Monsanto and Solutia from all liability in respect
to the Litigation once payment of the settlement and fulfillment of any
other obligations of the settlement have been effectuated. Pharmacia shall
nevertheless have a duty or prior consultation with New Monsanto and Solutia
concerning any settlement strategies or decision.

                           (c) In the event that any claims at issue, or
arguably at issue, in any Appeal and/or the Litigation are settled, Solutia
shall pay the full settlement amount and perform any obligations of Solutia
and/or Pharmacia set forth in the settlement agreement. In the event that
any claims at issue are not settled and a final, non-appealable judgment is
entered against Solutia and/or Pharmacia, Solutia shall pay directly and
otherwise fulfill all of Solutia's and Pharmacia's obligations pursuant to
such judgment. To the extent that Solutia fails to promptly and fully meet
its obligations with respect to the payment of any judgment or settlement or
with respect to other obligations arising out of any settlement or judgment
in any Appeal and/or the Litigation, Solutia shall enter into a consent
judgment in favor of Pharmacia and New Monsanto against Solutia in the
amount equal to the amount specified in the judgment or settlement minus any
amount paid by Solutia in satisfaction of the judgment or settlement. To the
extent that Solutia fails to promptly and fully meet its obligations with
respect to the payment of any judgment or settlement or with respect to
other obligations arising out of any settlement or judgment in any Appeal
and/or the Litigation, New Monsanto agrees to pay, perform or discharge such
liabilities and obligations when due and owing pursuant to the terms of the
Separation Agreement, as amended by the Separation Agreement Amendment (the
"Amended Separation Agreement"). To the extent that New Monsanto fails to
 ----------------------------
promptly and fully meet its obligations with respect to the payment of any
judgment or settlement when due and owing or with respect to other
obligations arising out of any settlement or judgment in any Appeal and/or
the Litigation, New Monsanto shall enter into a consent judgment in favor of
Pharmacia and against New Monsanto in the amount equal to the amount
specified in the judgment or settlement minus any aggregate amount paid by
Solutia and new Monsanto in satisfaction of the judgment or settlement.

                           (d) For purposes of any Appeal and settlement of
any Appeal only, to the extent the rights, duties, commitments and
obligations set forth in this Section 5 of the Protocol Agreement and the
Power of Attorney attached hereto as Exhibit A differ from or conflict with
the rights, duties, commitments and obligations of the parties as set forth
in the Amended Distribution Agreement or in the Amended Separation
Agreement, or any power of attorney granted in connection therewith, the
rights, duties, commitments and obligations in this Section 5 shall
supercede and take precedent over the rights, duties, commitments and
obligations set forth in the Amended Distribution Agreement or the Amended
Separation Agreement, or any power of attorney granted in connection
therewith, as the case may be.

                           (e) In the event that Solutia files or is subject
to any voluntary or involuntary bankruptcy proceeding, Solutia's rights
hereunder and Solutia's right to defend Pharmacia with respect to any Appeal
and/or the Litigation and the power of attorney with respect thereto
attached hereto as Exhibit A are automatically and immediately revoked. The
parties further agree that consent from relief from any automatic stay under
section 362 of the Untied States Bankruptcy Code is not necessary, but that
should a court rule otherwise, Solutia hereby consents to the entry of an
order granting relief from the stay in order to effectuate this paragraph
and agrees to provide all necessary cooperation. The parties further agree
that the Power of Attorney with respect to any Appeal and/or the Litigation
shall be immediately revoked.

                  Section 6. The power of attorney attached as
Exhibit 4.03(e) to the Amended Distribution Agreement is hereby revoked and is
of no further force or effect and is replaced by the power of attorney attached
hereto as Exhibit A, which shall be executed by Pharmacia. Pursuant to the
          ---------
power of attorney attached hereto as Exhibit A, the prosecution of any
Appeal and continued defense of the Litigation shall be managed by Solutia
at Solutia's expense. Solutia shall report to New Monsanto and Pharmacia all
material developments concerning the Litigation and any Appeal and shall
provide all information and documents reasonably requested by either New
Monsanto or Pharmacia. At their expense, New Monsanto and Pharmacia may
associate with and advise Solutia in the prosecution of any Appeal and
continued defense of the Litigation and Solutia shall allow Pharmacia and
New Monsanto to consult with and advise Solutia in connection with any
decision or strategy in any Appeal and the Litigation. Solutia shall also
fully inform Pharmacia and New Monsanto on an immediate basis and in writing
of any settlement discussions regarding the Litigation and/or any Appeal and
shall, subject to Section 5(b) above, consult fully with Pharmacia and New
Monsanto concerning any settlement strategies or decision.

                  Section 7. Solutia, Pharmacia and New Monsanto acknowledge
and agree that this Protocol Agreement shall not be enforceable as to New
Monsanto until the earlier of July 11, 2002 or the date upon which the New
Monsanto Special Committee approves of the provisions of this Protocol
Agreement and authorizes New Monsanto's execution of this Protocol
Agreement. In the event that the New Monsanto Special Committee does not
approve the provisions of, and does not authorize New Monsanto's execution
of, this Protocol Agreement on or before July 11, 2002, then Solutia,
Pharmacia and New Monsanto agree that New Monsanto will no longer be deemed
to be a party under this Protocol Agreement and will have no rights or
obligations hereunder, except that New Monsanto shall nevertheless retain
the rights and obligations set forth in Section 5(b)(i) above. Furthermore,
in said event, Solutia and Pharmacia

Agreement shall be deemed to be deleted in its entirety; (iv) Section 10 of
this Protocol Agreement shall be deemed amended by deleting everything after

                  Section 8. Other than as provided herein, neither
Pharmacia, New Monsanto nor Solutia has waived or compromised any of their
respective rights under the Amended Distribution Agreement. In addition, the
running of any limitations on the time for either Pharmacia, New Monsanto or
Solutia to assert any claims related to the Litigation under the Amended
Distribution Agreement is tolled until 120 days after final resolution of
any Appeal.

                  Section 9. Other than as provided herein, neither
Pharmacia nor New Monsanto has waived or compromised any of their respective
rights under the Amended Separation Agreement. In addition, the running of

any claims related to the Litigation under the Amended Separation Agreement
is tolled until 120 days after final resolution of any Appeal.

                  Section 10. Nothing herein is intended to nor shall be
construed to waive or limit any of the commitments and obligations of
Solutia to Pharmacia, New Monsanto or the Monsanto Group (and each of their
Representatives and Affiliates) set forth in the Amended Distribution
Agreement including, without limitation, Article IV thereof, or to waive or
limit any commitments and obligations of New Monsanto to Pharmacia or the
Pharmacia Group (and each of their Representatives and Affiliates) set forth
in the Amended Separation Agreement including, without limitation, Article
III thereof.

                  Section 11. Provided that Solutia promptly and fully
complies with, as conditions precedent, the commitments, obligations and
duties set forth above, Pharmacia and New Monsanto each agree that Solutia's
failure to post a bond pending an Appeal does not constitute a breach of
Solutia's commitments and obligations to Pharmacia or New Monsanto under the
Amended Distribution Agreement.

                  Section 12. Provided that New Monsanto promptly and fully
complies with, as conditions precedent, the commitments, obligations and

commitments and obligations to Pharmacia under the Amended Separation
Agreement.

Monsanto and Pharmacia, each party hereto will pay its own costs and
expenses incident to its negotiation and preparation of this Protocol
Agreement, including the fees, expenses and disbursement of its counsel.

any party hereto.
