Liens) in and to such released Collateral unless the conditions in Section 3

Company, shall) subordinate the Liens of the Trustee and the 2009

the Senior Collateral has been released and (2) all the Lender Obligations

amount of $50,000,000 and (y) has a tenor of no less than 364 days. In

released automatically (and without any action or consent by the Trustee or

disposed of and the proceeds thereof applied to the Senior Secured
Obligations to the extent required by the Solutia Credit Agreement or,
alternatively, paid over to the Trustee for application to the Junior
Secured Obligations. In either such event, the Trustee shall execute and
deliver such documents, and do such other acts and things, as may be
reasonably requested by the Company to confirm such release.

Notwithstanding anything to the contrary herein, in the other Junior
Security Documents or in the 2009 Notes Indenture, the Trustee shall not be
entitled to exercise (whether upon its own initiative or at the direction of
any one or more of the 2009 Noteholders) any rights or remedies in respect
of the Liens under the Junior Security Documents, or to enforce any of the
Junior Security Documents, until the Senior Payment Date; provided that
                                                          --------
nothing herein shall prevent the 2009 Noteholders or the Trustee from
declaring an "Event of Default" under the 2009 Notes Indenture, accelerating
the Junior Secured Obligations, bringing suit thereon, filing proofs of
claims or otherwise exercising rights or remedies under the 2009 Notes
Indenture or the Junior Security Documents other than exercising rights or
remedies in respect of their Liens under the Junior Security Documents.

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

communications shall, when delivered or telecopied, be effective when

                  6.02. Waivers. No failure on the part of the Collateral
                        -------
Agent to exercise, and no course of dealing with respect to, and no delay in
exercising, any right, power or remedy hereunder shall operate as a waiver
thereof; nor shall any single or partial exercise of any such right, power
or remedy hereunder preclude any other or further exercise thereof or the
exercise of any other right, power or remedy. The remedies herein are
cumulative and are not exclusive of any remedies provided by law.

                  6.03. Amendments, Etc. Except as otherwise herein
                        ---------------
expressly provided, the terms of this Agreement and the other Junior
Security Documents may be waived, altered or amended only by an instrument
in writing duly executed by each Securing Party and the Trustee, with the
consent of the Collateral Agent (prior to the Senior Payment Date only) and
(if and to the extent required by the 2009 Notes Indenture) the holders of
the percentage of the principal amount of the 2009 Notes required by the
2009 Notes Indenture; provided that (i) no such amendment shall adversely
                      --------
affect the relative rights of any Senior Secured Party or 2009 Noteholder as
against any other Senior Secured Party or 2009 Noteholder without the prior
written consent of such first Senior Secured Party or 2009 Noteholder, and
(ii) any amendment or waiver (other than an amendment or a waiver releasing
any Collateral) of any provision of any Senior Security Document not
inconsistent with clause (i) above shall, at the written election of the
Company delivered to the Trustee (and without the action by any other
party), be deemed to be an amendment or a waiver of the corresponding
provision, if any, of the Junior Security Agreement or other Junior Security
Document with the same effect as if such amendment or waiver of such
provision had been agreed to in writing in compliance with this Section
6.03. Any such amendment or waiver shall be binding upon the Collateral
Agent (to the extent it has consented thereto), the Trustee, each Senior
Secured Party (to the extent the Collateral Agent has consented thereto),
each 2009 Noteholder and each Securing Party.

                  6.04. Governing Law. This Agreement shall be governed by,
                        -------------
and construed in accordance with, the law of the State of New York.

                  6.05. Jurisdiction. Each party hereto hereby irrevocably
                        ------------
and unconditionally submits, for itself and its property, to the
nonexclusive jurisdiction of any New York State court or federal court of
the United States of America sitting in New York City, and any appellate
court from any thereof, in any action or proceeding arising out of or
relating to this Agreement or any Junior Security Document, or for
recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of
any such action or proceeding may be heard and determined in any such New
York State court or, to the extent permitted by law, in such federal court.
Each party hereto agrees that a final judgment in any such action or
proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on the judgment or in any other manner provided by law. Nothing in this
Agreement or any other Junior Security Document shall affect any right that
any party may otherwise have to bring any action or proceeding relating to
this Agreement or any other Junior Security Document in the courts of any
jurisdiction.

                  6.06. Successors and Assigns. This Agreement shall be
                        ----------------------
binding upon and inure to the benefit of the respective successors and
assigns of each of the parties hereto (provided that no Securing Party shall
                                       --------
assign or transfer its rights or obligations hereunder without the prior
written consent of the Collateral Agent and the Trustee).

                        ------------
number of counterparts, all of which taken together shall constitute one and
the same instrument and any of the parties hereto may execute this Agreement
by signing any such counterpart. Delivery of an executed counterpart of this
Agreement by facsimile or other electronic transmission shall constitute
valid delivery of an executed counterpart hereof.

                  6.08. Severability. If any provision hereof is invalid and
                        ------------
unenforceable in any jurisdiction, then, to the fullest extent permitted by
law, (a) the other provisions hereof shall remain in full force and effect
in such jurisdiction and (b) the invalidity or unenforceability of any
provision hereof in any jurisdiction shall not affect the validity or
enforceability of such provision in any other jurisdiction.

                  6.09. Captions. The captions and section headings
                        --------
appearing herein are included solely for convenience of reference and are
not intended to affect the interpretation of any provision of this
Agreement.

                  6.10. Additional Subsidiary Guarantors. Pursuant to
                        --------------------------------
Section 4.19 of the 2009 Notes Indenture, any Subsidiary of the Company that
becomes a Subsidiary Guarantor thereunder after the date hereof, shall
become a "Subsidiary Guarantor" under this Agreement, and shall grant liens
on all property owned by it that constitutes Collateral under the Junior
Security Documents, by executing and delivering to the Collateral Agent and
the Trustee a Guarantee Assumption Agreement in the form of Exhibit A
hereto. Accordingly, upon the execution and delivery of any such Guarantee
Assumption Agreement by any such Subsidiary, such new Subsidiary shall
automatically and immediately, and without any further action on the part of
any Person, become a "Subsidiary Guarantor" and a "Securing Party" for all
purposes of this Agreement.

                  6.11. Termination. This Agreement may be terminated by the
                        -----------
Company, the Collateral Agent and the Trustee upon a new senior credit
facility being entered into by the Company which is a "Credit Facility"
under and as defined in the 2009 Notes Indenture, but is not the Solutia
Credit Agreement (as defined hereunder), provided that substantially
                                         --------
contemporaneously therewith a replacement of this Agreement and the Junior
Security Agreement are entered into on substantially the same terms hereof
and thereof, which new agreements shall reflect the new parties thereto (and
shall be on terms not any less favorable to the Trustee and the 2009
Noteholders than the terms hereof and thereof); provided, that the Trustee
shall be entitled to receive (a) written instructions directing it to
terminate this Agreement and (b) such other documents as it may reasonably
request or require evidencing that the terms of such new agreements are not
any less favorable to the Trustee and the 2009 Noteholders than the terms
hereof and thereof; provided further that nothing herein shall require the
Collateral Agent to deliver any such instructions or directions.

and obligations thereof) and that henceforth the Existing Collateral Agent

Agent consents to the terms hereof.
