be established at a banking institution to be selected by the Collateral Trustee
one or more cash collateral accounts (collectively, the "SHARED COLLATERAL
ACCOUNT"), which

          (i)  to the extent of all Investment Property or Financial Assets
     (other than cash) shall be a "securities account" (as defined in Section

          (ii) to the extent of any cash, shall be a deposit account in respect
     of which the Collateral Trustee is the customer (as contemplated by
     9-104(a)(3) of the Uniform Commercial Code),

into which there shall be deposited from time to time the cash proceeds of any
of the Shared Collateral (including dividends, distributions, interest, profits
and income thereon) required to be delivered to the Collateral Trustee pursuant
hereto and into which the Grantors may from time to time deposit any additional
amounts that any of them wishes to pledge to the Collateral Trustee for the
benefit of the Sharing Secured Parties as additional collateral security
hereunder. The balance from time to time in the Shared Collateral Account shall
constitute part of the Shared Collateral hereunder and shall remain in the
Shared Collateral Account until applied as hereinafter provided. The Collateral
Trustee may (and, if instructed by the Collateral Agent (or, if the Requisite
Sharing Secured Parties shall have assumed the right and authority of the
Collateral Agent as contemplated by Section 3.04(b) of the Sharing Intercreditor
Agreement, by the Requisite Sharing Secured Parties), shall) in its (or their)
discretion apply or cause to be applied (subject to collection) the balance from
time to time standing to the credit of the Shared Collateral Account to the
payment of Sharing Obligations in the manner specified in Section 5.09 to the
extent necessary to result in the payment of the Sharing Obligations then due
and payable. In addition, the Company may at any time request that the balance
from time to time standing to the credit of the Shared Collateral Account be
applied to the payment of Sharing Obligations in the manner specified in Section
5.09 to the extent necessary to result in the payment of the Sharing Obligations
then due and payable. The balance from time to time in the Shared Collateral
Account shall be subject to withdrawal only as provided herein.

          4.02 PROCEEDS OF PLEDGED DEBT. If requested by the Collateral Trustee
(acting at the request or with the consent of the Collateral Agent or the
Requisite Secured Parties as provided in Section 3.04(b) of the Sharing
Intercreditor Agreement) at any time after the occurrence and during the
continuance of an Event of Default, each Grantor shall instruct all Restricted
Subsidiaries obligated in respect of all Pledged Debt to make all payments in
respect of the Pledged Debt directly to the Collateral Trustee. All payments
made to the Collateral Trustee, as provided in the preceding sentence, shall be
immediately deposited by the Collateral Trustee in the Shared Collateral
Account. In addition to the foregoing, each Grantor agrees that, at any time
after the occurrence and during the continuance of an Event of Default, if the
proceeds of any Shared Collateral hereunder (including the payments made in
respect of Pledged Debt) shall be received by it, such Grantor shall, upon the
request of the Collateral Trustee, as

<Page>

promptly as possible deposit such proceeds into the Shared Collateral Account.
Until so deposited, all such proceeds shall be held in trust by such Grantor for
and as the property of the Collateral Trustee and shall not be commingled with
any other funds or property of such Grantor.

          4.03 INVESTMENT OF BALANCE IN SHARED COLLATERAL ACCOUNT. The cash
balance standing to the credit of the Shared Collateral Account shall be
invested from time to time in such Permitted Investments as the Collateral Agent
shall determine, which Permitted Investments shall be held in the name and be
under the control of the Collateral Trustee (and, if the Shared Collateral
Account is a securities account, credited to the Shared Collateral Account),
PROVIDED that at any time after the occurrence and during the continuance of an
Event of Default, the Collateral Trustee may (and, if instructed by the
Collateral Agent (or, if the Requisite Sharing Secured Parties shall have
assumed the right and authority of the Collateral Agent as contemplated by
Section 3.04(b) of the Sharing Intercreditor Agreement, by the Requisite Sharing
Secured Parties), shall) in its (or their) discretion at any time and from time
to time elect to liquidate any such Permitted Investments and to apply or cause
to be applied the proceeds thereof in the manner specified in Section 5.09 to
the extent necessary to result in the payment of the Sharing Obligations then
due and payable.

of the pledge and security interest pursuant to Section 3, the Grantors hereby
jointly and severally agree with the Sharing Secured Parties as follows:

          5.01 DELIVERY AND OTHER PERFECTION. Each Grantor shall:

     Collateral Trustee such shares or securities so received by such Grantor
     (together with the certificates for any such shares and securities duly
     endorsed in blank or accompanied by undated stock powers duly executed in
     blank), all of which thereafter shall be held by the Collateral Trustee,
     pursuant to the terms of this Agreement, as part of the Shared Collateral
     or (y) take such other action as the Collateral Agent or the Collateral
     Trustee shall deem reasonably necessary or appropriate to duly record the

     said clauses (b)(i) and (b)(ii);

          (b) deliver and pledge to the Collateral Trustee any and all

          (c) give, execute, deliver, file, register and record, authorize or
     obtain all such financing statements, notices, instruments, documents,
     agreements or other papers, and take such other action, as may be necessary
     or desirable (in the reasonable judgment of the Collateral Agent) to
     create, preserve, publish notice of, perfect, validate or preserve the
     priority of the security interest granted pursuant hereto or to enable the
     Collateral Trustee to exercise and enforce its rights hereunder with
     respect to such pledge and security interest, including causing any or all
     of the Stock Collateral to be transferred of

<Page>

     record into the name of the Collateral Trustee or its nominee (and the
     Collateral Trustee agrees that if any Stock Collateral is transferred into
     its name or the name of its nominee, the Collateral Trustee will thereafter

     communications received by it with respect to the Stock Collateral pledged
     by such Grantor hereunder);

          (d) keep accurate books and records relating to the Shared Collateral,

          (e) permit representatives of the Collateral Agent or the Collateral
     Trustee, upon reasonable notice, at any time during normal business hours
     to inspect and make abstracts from its books and records pertaining to the
     Shared Collateral and, during the continuance of an Event of Default,
     permit representatives of the Collateral Trustee to be present at such
     Grantor's place of business to receive copies of all communications and
     remittances relating to the Shared Collateral, and forward copies of any
     notices or communications received by such Grantor with respect to the
     Shared Collateral, all in such manner as the Collateral Agent or Collateral
     Trustee may reasonably require.

          5.02 OTHER FINANCING STATEMENTS AND LIENS. Except as otherwise
permitted in Section 6.02(a) of the Solutia Credit Agreement, without the prior
written consent of the Collateral Trustee (granted with the authorization of the
Collateral Agent), no Grantor shall file or suffer to be on file, or authorize
or permit to be filed or to be on file, in any jurisdiction, any financing
statement or like instrument with respect to the Shared Collateral in which the
Collateral Trustee is not named as the sole secured party for the benefit of the
Sharing Secured Parties.

voting, consensual and other powers of ownership pertaining to the Stock
Collateral for all purposes not inconsistent with the terms of this Agreement,
the Sharing Intercreditor Agreement, the Solutia Credit Agreement or any other
instrument or agreement referred to herein or therein, PROVIDED that the
Grantors jointly and severally agree that they will not vote the Stock
Collateral in any manner that results in a violation of the terms of this
Agreement, the Sharing Intercreditor Agreement, the Solutia Credit Agreement or
any such other instrument or agreement; and the Collateral Trustee shall execute
and deliver to the Grantors or cause to be executed and delivered to the
Grantors all such proxies,

powers of attorney, dividend and other orders, and all such instruments, without
recourse, as the Grantors may reasonably request for the purpose of enabling the
Grantors to exercise the rights and powers that they are entitled to exercise
pursuant to this Section 5.04(2).

          (3) DIVIDENDS, ETC. Unless and until an Event of Default has occurred
and is continuing, the Grantors shall be entitled to receive and retain any
dividends on the Stock Collateral paid in cash out of earned surplus.

          (4) RIGHTS FOLLOWING DEFAULT. If any Event of Default shall have
occurred, then so long as such Event of Default shall continue, and whether or

theretofore applied to the Sharing Obligations), be returned by the Collateral
Trustee to the Grantors.

     designated in the Collateral Trustee's request;

          (b) the Collateral Trustee may (acting at the request or with the
     consent of the Collateral Agent or the Requisite Secured Parties as
     provided in Section 3.04(b) of the Sharing Intercreditor Agreement) make
     any reasonable compromise or settlement deemed desirable with respect to
     any of the Shared Collateral and may extend the time of payment, arrange
     for payment in installments, or otherwise modify the terms of, any of the
     Shared Collateral;

          (c) the Collateral Trustee shall have all of the rights and remedies
     with respect to the Shared Collateral of a secured party under the Uniform
     Commercial Code (whether or not the Uniform Commercial Code is in effect in
     the jurisdiction where the rights and remedies are asserted) and such
     additional rights and remedies to which a secured party is entitled under
     the laws in effect in any jurisdiction where any rights and remedies
     hereunder may be asserted, including the right, to the fullest extent
     permitted by applicable law, to exercise all voting, consensual and other
     powers of ownership

<Page>

     pertaining to the Shared Collateral as if the Collateral Trustee were the
     sole and absolute owner thereof (and each Grantor agrees to take all such
     action as may be appropriate to give effect to such right);

          (d) the Collateral Trustee in its discretion may, in its name or in
     the name of any Grantor or otherwise, demand, sue for, collect or receive
     any money or property at any time payable or receivable on account of or in
     exchange for any of the Shared Collateral, but shall be under no obligation
     to do so; and

          (e) the Collateral Trustee may (acting at the request or with the
     consent of the Collateral Agent or the Requisite Secured Parties as
     provided in Section 3.04(b) of the Sharing Intercreditor Agreement), upon
     ten Business Days' prior written notice to the Grantors of the time and
     place, with respect to the Shared Collateral or any part thereof which
     shall then be or shall thereafter come into the possession, custody or
     control of the Collateral Trustee, the Sharing Secured Parties or any of
     their respective agents, sell, lease, assign or otherwise dispose of all or
     any part of such Shared Collateral, at such place or places as the
     Collateral Trustee deems best, and for cash or for credit or for future
     delivery (without thereby assuming any credit risk), at public or private
     sale, without demand of performance or notice of intention to effect any
     such disposition or of the time or place thereof (except such notice as is
     required above or by applicable statute and cannot be waived), and the
     Collateral Trustee or any Sharing Secured Party or anyone else may be the
     purchaser, lessee, assignee or recipient of any or all of the Shared
     Collateral so disposed of at any public sale (or, to the extent permitted
     by law, at any private sale) and thereafter to the fullest extent permitted
     by law hold the same absolutely, free from any claim or right of whatsoever
     kind, including any right or equity of redemption (statutory or otherwise),
     of the Grantors, any such demand, notice and right or equity being hereby
     expressly waived and released, to the fullest extent permitted by law. The
     Collateral Trustee may, without notice or publication, adjourn any public
     or private sale or cause the same to be adjourned from time to time by
     announcement at the time and place fixed for the sale, and such sale may be
     made at any time or place to which the sale may be so adjourned.

The proceeds of each collection, sale or other disposition under this Section
5.05 shall be applied in accordance with Section 5.09.

          The Grantors recognize that, by reason of certain prohibitions
contained in the Securities Act of 1933, as amended, and applicable state
securities laws, the Collateral Trustee (acting at the request or with the
consent of the Collateral Agent or the Requisite Secured Parties as provided in
Section 3.04(b) of the Sharing Intercreditor Agreement) may be compelled, with
respect to any sale of all or any part of the Shared Collateral, to limit
purchasers to those who will agree, among other things, to acquire the Shared
Collateral for their own account, for investment and not with a view to the
distribution or resale thereof. The Grantors acknowledge that any such private
sales may be at prices and on terms less favorable to the Collateral Trustee
than those obtainable through a public sale without such restrictions, and,
notwithstanding such circumstances, agree that any such private sale shall be
deemed to have been made in a commercially reasonable manner and that the
Collateral Trustee shall have no obligation to

<Page>

engage in public sales and no obligation to delay the sale of any Shared
Collateral for the period of time necessary to permit the respective Issuer or
issuer thereof to register it for public sale.

          5.06 DEFICIENCY. If the proceeds of sale, collection or other
realization of or upon the Shared Collateral pursuant to Section 5.05 are
insufficient to cover the costs and expenses of such realization and the payment
in full of the Sharing Obligations, the Grantors shall remain liable for any
deficiency to the extent obligated under the respective Debt Instruments to
which the Grantors are party.

          5.07 LOCATIONS; NAMES. Without at least 30 days' prior written notice
to the Collateral Agent and the Collateral Trustee, no Grantor shall change its
"location" (as defined in Section 9-307 of the Uniform Commercial Code) or
change its name from the name shown as its current legal name on Annex 1.

          5.08 PRIVATE SALE. The Collateral Trustee and the Sharing Secured
Parties shall incur no liability as a result of the sale of the Shared
Collateral, or any part thereof, at any private sale pursuant to Section 5.05
conducted in a commercially reasonable manner. Each Grantor hereby waives any
claims against the Collateral Trustee or any Sharing Secured Party arising by
reason of the fact that the price at which the Shared Collateral may have been
sold at such a private sale was less than the price which might have been
obtained at a public sale or was less than the aggregate amount of the Sharing
Obligations, even if the Collateral Trustee accepts the first offer received and
does not offer the Shared Collateral to more than one offeree.

          5.09 APPLICATION OF PROCEEDS OF SHARED COLLATERAL. The proceeds of any
collection, sale or other realization of all or any part of the Shared
Collateral pursuant hereto, and any other cash at the time held by the
Collateral Trustee under Section 4 or this Section 5, shall be applied by the
Collateral Trustee in the manner set forth in Section 4.01 of the Sharing
Intercreditor Agreement; PROVIDED that if the Sharing Intercreditor Agreement
shall not be in effect, such proceeds and cash shall be applied in the manner
set forth in Section 5.02 of the Non-Sharing Intercreditor Agreement.

          5.10 ATTORNEY-IN-FACT. Without limiting any rights or powers granted
by this Agreement to the Collateral Trustee while no Event of Default has
occurred and is continuing, upon the occurrence and during the continuance of
any Event of Default the Collateral Trustee is hereby appointed the
attorney-in-fact of each Grantor for the purpose of carrying out the provisions
of this Section 5 and taking any action and executing any instruments which the
Collateral Trustee (acting at the request or with the consent of the Collateral
Agent or the Requisite Secured Parties as provided in Section 3.04(b) of the
Sharing Intercreditor Agreement) may reasonably deem necessary or advisable to
accomplish the purposes hereof, which appointment as attorney-in-fact is
irrevocable and coupled with an interest. Without limiting the generality of the
foregoing, so long as the Collateral Trustee shall be entitled under this
Section 5 to make collections in respect of the Shared Collateral, the
Collateral Trustee shall have the right and power to receive, endorse and
collect all checks made payable to the order of any Grantor representing any
dividend, payment or other distribution in respect of the Shared Collateral or
any part thereof and to give full discharge for the same.

<Page>

          5.11 PERFECTION. Prior to or concurrently with the execution and
delivery of this Agreement, each Grantor shall (i) file such financing
statements and other documents in such offices as the Collateral Trustee may
request to perfect the security interests granted by Section 3 of this Agreement
and (ii) deliver to the Collateral Trustee all certificates evidencing any of
the Pledged Stock, accompanied by undated stock powers duly executed in blank,
and, to the extent required under Section 5.01(b), all promissory notes and
other instruments evidencing any Pledged Debt identified in Annex 4. Without
limiting the foregoing, each Grantor consents that Uniform Commercial Code
financing statements may be filed describing the Shared Collateral as set forth
in Section 3.

          5.12 TERMINATION. This Agreement and the security interests granted
hereby shall cease to be effective

          (a) with respect to the Senior Notes Obligations on the earlier of the
     date (i) on which all the Senior Notes Obligations shall have been paid in
     full to the holders thereof and (ii) that is ten days after the provisions
     of the Senior Notes Documents that require equal and ratable security shall
     be held to be invalid, void or unenforceable by the final judgment of a
     court of competent jurisdiction, no longer subject to appeal or review and

          (b) when all of the Non-Sharing Obligations have been paid in full,
     all Designated Letters of Credit and Letters of Credit issued under the
     Solutia Credit Agreement have expired or terminated and the Solutia
     Commitments have been terminated and the Solutia Administrative Agent, the
     Astaris Administrative Agent and the Co-gen Agent have each given written
     notification thereof to the Collateral Trustee, or when the Collateral
     Agent shall have authorized the release of the Liens created hereunder and
     the termination of this Agreement pursuant to Section 7 of the Sharing
     Intercreditor Agreement,

whereupon, in the case of the foregoing clause (b), the Collateral Trustee shall
forthwith cause to be assigned, transferred and delivered, against receipt but
without any recourse, warranty or representation whatsoever, any remaining
Shared Collateral and money received in respect thereof, to or on the order of
the respective Grantor. The Collateral Trustee shall, at the expense of the
Company, also execute and deliver to the respective Grantor upon such
termination such Uniform Commercial Code termination statements and such other
documentation as shall be reasonably requested by the respective Grantor to
effect the termination and release of the Liens on the Shared Collateral

          Notwithstanding the foregoing (other than paragraph (a) of this
Section 5.12), any release of such Grantor or any Shared Collateral after the
occurrence and during the continuance of a Triggering Event (as defined in the
Sharing Intercreditor Agreement) shall be subject to the prior approval of the
Requisite Sharing Secured Parties.

          5.13 FURTHER ASSURANCES. Each Grantor agrees that, from time to time
upon the written request of the Collateral Trustee, such Grantor will execute
and deliver such further documents and do such other acts and things as the
Collateral Trustee may reasonably request in order fully to effect the purposes
of this Agreement.

          Section 2. PRIORITY OF LIENS. It is the intent of the parties that the
Liens created pursuant to the Junior Security Documents in favor of the Trustee
shall be junior and subject in all respects to the Liens created pursuant to the
Senior Non-Sharing Security Documents. Accordingly, anything herein or in any of
the other Junior Security Documents, the 2009 Notes Indenture or any other
agreement or instrument between any of the Securing Parties and any of the 2009
Noteholders to the contrary notwithstanding, the Trustee, on behalf of itself
and each of the 2009 Noteholders, hereby agrees for the benefit of the
Collateral Agent and the Senior Secured Parties that, notwithstanding the time
of filing or recording of the Liens created by the Junior Security Documents, to
the extent securing such Lien in favor of any of the Senior Secured Parties is
valid and enforceable, the Liens created pursuant to the Junior Security
Documents shall be subordinate to the Liens created pursuant to the Senior
Non-Sharing Security Documents in any "Collateral" under and as defined in the
Senior Non-Sharing Security Documents.

          The Collateral Agent and the Senior Secured Parties may release their
Liens against all or any portion of the Collateral at any time but are not
entitled to release or affect the Liens of the Trustee which shall thereafter
continue to be valid and enforceable (as first priority Liens) in and to such
released Collateral unless the conditions in Section 3 hereof are met, at which
time the Liens of the Trustee shall be released. If (i) the Collateral Agent and
the Senior Secured Parties have released all or a portion of their Liens, (ii)
the conditions for an automatic release of the Liens of the Junior Secured
Parties (as defined in the Junior Security Agreement) securing the Junior
Secured Obligations against the Senior Collateral set forth in Section 3 shall
not have been satisfied and (iii) at any later time such Liens in favor of the
Collateral Agent and the Senior Secured Parties are reinstated or re-granted,
the Collateral Agent shall, subject to the applicable provisions of the 2009
Notes Indenture and the Junior Security Documents, be entitled to (and at the
request of the Company, shall) subordinate the Liens of the Trustee and the 2009
Noteholders under the Junior Security Documents to such reinstated Liens in
favor of the Collateral Agent and the Senior Secured Parties, such subordination
to be on the same terms and subject to the same conditions as provided in the
first paragraph of this Section 2.

          The Trustee, on behalf of itself and each 2009 Noteholder, hereby
waives any requirement on the part of the Collateral Agent or the Senior Secured
Parties in respect of marshalling of assets upon any exercise of remedies by the
Collateral Agent or the Senior Secured Parties and any requirement that the
Collateral Agent or any Senior Secured Party exercise remedies with respect to
collateral security for the Senior Secured Obligations in any particular order
or any particular manner.

          Section 3. RELEASE OF LIENS AND GUARANTEES. The Liens of the Junior
Secured Parties securing the Junior Secured Obligations against the Senior
Collateral will be released automatically (and without any action or consent by
the Trustee or the 2009 Noteholders) at such time, if (1) the Lien of the
Collateral Agent against the Senior Collateral has been released and (2) all the
Solutia Credit Agreement Obligations are unsecured and the revolving facility
thereunder (x) is in a minimum amount of $50,000,000 and (y) has a tenor of no
less than 364 days. In addition, the Liens of the Junior Secured Parties
securing the Junior Secured Obligations against any particular item of Senior
Collateral will be released automatically (and without any action or consent by
the Trustee or the 2009 Noteholders) at such time as such item is sold or
otherwise disposed of and the proceeds thereof applied to the Senior Secured

                         JUNIOR INTERCREDITOR AGREEMENT

                                      - 7 -

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.

          Section 4. LIMITATION ON RIGHTS AND REMEDIES. 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.

          Section 5. NOTICE OF SENIOR PAYMENT DATE. The Collateral Agent shall
promptly notify the Trustee of the occurrence of the Senior Payment Date.

          Section 6. MISCELLANEOUS
