                             RETENTION AGREEMENT
                             -------------------

This Retention Agreement ("Agreement") is entered into by and between
Solutia Inc., a Delaware corporation ("Solutia") and _______________
("Employee"), as of the date indicated on the signature page attached
hereto.

WHEREAS, Employee and Solutia had previously entered into a retention
agreement prior to Solutia's commencement of its Chapter 11 Bankruptcy
filing ("Prior Agreement"); and

WHEREAS, as a result of the Chapter 11 Bankruptcy filing, the Prior
Agreement became subject to the United States Bankruptcy Court's approval;
and

WHEREAS, the Bankruptcy Court ruled that the Prior Agreement was null and
void from the beginning; and

WHEREAS, the Bankruptcy Court granted approval of this revised Retention
Agreement; and

WHEREAS, Solutia believes that establishing an incentive arrangement for
Employee will increase the likelihood that Solutia will continue to have
Employee's advice, counsel, leadership and dedication.

NOW, THEREFORE, for good and valuable consideration, Solutia and Employee,
intending to be bound, agree as set forth in this Agreement.

1) EMPLOYMENT
   ----------

   a) Employee's employment with Solutia during the Employment Period
      will be under the same terms and conditions as those that applied
      immediately prior to the date of this Agreement (or as subsequently
      amended from time to time). The "Employment Period" for purposes of
      this Agreement shall mean the period beginning on the date of this
      Agreement and ending six months after the Emergence Date (as
      defined below).

   b) Nothing in this Agreement is intended, and nothing herein will be
      construed as limiting the ability of Employee or Solutia to
      terminate such employment. Moreover, Employee understands that
      their employment will remain as an "at will" relationship.

   c) During the Employment Period, Employee will:

      i)   Devote all business time to the duties of employment with Solutia;

                                 Page 1 of 5

      ii)  perform all duties of employment with Solutia faithfully and
           effectively and to the best of Employee's ability;

      iii) act in the best interests of Solutia and its shareholders and
           engage in no conflict of interest with Solutia.

2) COMPENSATION; SPECIAL AWARD
   ---------------------------

a) During the Employment Period, Solutia will compensate Employee in
   accordance with the terms and conditions in effect immediately
   prior to the date of this Agreement (as amended from time to time),
   including eligibility for an award under the terms of the Solutia
   Inc. Annual Incentive Plan ("AIP"). Nothing in this Agreement shall
   be construed to provide Employee with the right to participate in
   the AIP or any other incentive or benefit plan if Solutia
   determines to change or terminate such plan and the change or
   termination is generally applicable to employees who are similarly
   situated to Employee.

b) In addition to the foregoing, subject to Section 2(c) below,
   Employee shall receive a special incentive award (the "Special
   Award"). The amount of the Special Award will be ____% of
   Employee's base salary as of the date of the Special Award payment.

c) The Special Award will be paid in four (4) equal installments, less
   applicable taxes and withholdings, on the following dates and,
   provided that the Employee has fulfilled the obligations set forth
   in Section 1 of this Agreement, in the judgment of the CEO of
   Solutia or his designee:

      i)   On or about June 30, 2004, Solutia will pay to Employee 25% of the
           Special Award, less applicable taxes and withholdings, provided
           that Employee is employed by Solutia on such date.

      ii)  On or about December 31, 2004, Solutia will pay to Employee 25% of
           the Special Award, less applicable taxes and withholdings, provided
           that Employee is employed by Solutia on such date.

      iii) As soon as practicable following the time, if ever, at which both
           (x) the United States Bankruptcy Court for the Southern District of
           New York shall have confirmed a plan of reorganization of Solutia
           under Chapter 11 of the United States Bankruptcy Code and (y) such
           confirmation shall have become non-appealable (the "Emergence
           Date"), Solutia will pay to Employee 25% of the Special Award, less
           applicable taxes and withholdings, provided that Employee is
           employed by Solutia on such date.

      iv)  On the six (6) month anniversary of the Emergence Date, Solutia
           will pay to Employee 25% of the Special Award, less applicable
           taxes and withholdings, provided that Employee is employed by
           Solutia on such date.

                                Page 2 of 5

3) TERMINATION OF EMPLOYMENT
   -------------------------

   a) If, prior to an applicable installment payment date during the
      Employment Period, Employee (i) retires or voluntarily terminates
      employment with Solutia (other than as a result of death or
      Disability); (ii) announces his or her intent to so retire or
      terminate employment; or (iii) is terminated by Solutia for Cause,
      Employee will not receive any portion of the Special Award
      installment payment applicable to that installment period. "Cause"
      as used in this Agreement shall include willful misconduct,
      dishonesty, insubordination, conviction of a felony or its
      equivalent, negligence in the performance of Employee's duties,
      the illegal use of drugs or controlled substances and violation of
      Solutia's policies (including without limitation Solutia's
      Guidelines for Employee Conduct) in such a manner as to expose the
      employer to administrative, civil or criminal liability;

   b) If, prior to an applicable installment payment date during the
      Employment Period, Employee is terminated other than for Cause,
      Solutia shall pay to Employee in a lump sum, less applicable taxes
      and withholdings, any unpaid amounts that would have otherwise been
      payable to Employee pursuant to Section 2(b).

   c) If Employee is not actively employed for the entire installment
      period due to disability, sick leave, family leave, or other
      approved leave of absence, but is otherwise eligible for a Special
      Award, the Award will be pro-rated to cover only the time actively
      employed plus any qualifying leave (up to 12 weeks) under the
      federal Family Medical Leave Act, but will not cover any other
      disability or other leave. Employee must return to active
      employment in order to qualify for the Special Award installment,
      and will be paid only after he or she so returns.

   d) Payment of the Special Award terminates any and all obligations of
      Solutia under this Agreement.

   e) Solutia retains the right to condition payment of any portion of
      the Special Award on Employee signing a waiver and release, in a
      form acceptable to Solutia.

4) GENERAL
   -------

   a) Employee agrees not to disclose the existence of this Agreement or
      any of its terms to anyone other than Employee's spouse and a
      financial or legal advisor who agrees in writing to be bound not to
      make any such disclosure. Notwithstanding anything to the contrary
      in this Agreement, in the event this Agreement or its terms are
      disclosed by Employee, Employee's spouse or a legal or financial
      advisor, Employee will not receive any portion of the Special
      Award.

   b) All amounts required by law to be withheld from any payment made
      pursuant to this Agreement, including any and all amounts required
      to be withheld by the

                                Page 3 of 5

      Internal Revenue Code or by the Federal Insurance Contribution Act,
      any applicable state or foreign country's income tax act, any
      applicable city, county or municipality's earnings or income tax
      act, will be withheld.

   c) This Agreement will be binding upon and inure to the benefit of
      Employee and Employee's estate, and Solutia and any successor,
      direct or indirect, of Solutia, whether such succession, direct or
      indirect, of Solutia, results from a merger, consolidation,
      liquidation, reorganization, purchase of securities, acquisition of
      assets or otherwise.

   d) The interests of Employee under this Agreement are not subject to
      the claims of Employee's creditors and may not be voluntarily or
      involuntarily sold, transferred, alienated, assigned, pledged,
      anticipated or encumbered. Any attempt by Employee or any other
      person or entity to sell, transfer, alienate, assign, pledge,
      anticipate, encumber, charge or otherwise dispose of any right to
      benefits payable hereunder will be void and shall terminate any
      obligation of Solutia hereunder to make payment. At no time will
      any interest or other charge be due or payable on any amounts owing
      hereunder.

   e) The payment provided under this Agreement is not intended to
      qualify under Section 401 of the Internal Revenue Code and will be
      paid from the general assets of Solutia or a third party. Nothing
      contained herein shall require Solutia to segregate any monies from
      its general funds or to create any trusts, or to make any special
      deposits for amounts payable to Employee. In no case will any
      amounts paid under this Agreement be taken into account in
      determining any of Employee's Solutia benefits, including without
      limitation savings and investment plan contributions, pension, life
      insurance and disability or in determining any other incentive
      award or compensation.

   f) Any provision in this Agreement which is prohibited or
      unenforceable in any jurisdiction will, as to such jurisdiction, be
      ineffective only to the extent of such prohibition or
      unenforceability without invalidating or affecting the remaining
      provisions hereof, and any such prohibition or unenforceability in
      any jurisdiction will not invalidate or render unenforceable such
      provision in any other jurisdiction.

   g) Solutia has full power and authority in its sole discretion to
      construe, interpret, and administer this Agreement. Decisions of
      Solutia shall be final, conclusive, and binding on all parties
      hereto.

   h) This Agreement will in all respects be governed by, and construed
      in accordance with, the laws of the State of Delaware, without
      reference to conflicts of law principles thereunder.

   i) This Agreement constitutes the entire agreement between the parties
      with respect to the subject matter hereof and supersede all prior
      agreements, oral and

                                Page 4 of 5

      written, between the parties hereto with respect to the subject matter
      hereof, if any. Separate copies of this document shall constitute
      original documents which may be signed separately, but which together
      will constitute one single agreement.

   j) In the event of any breach by Employee of any term or condition set
      forth in this Agreement, Employee's right to receive the Special
      Payment shall immediately be forfeited.

   k) The Employee acknowledges that Employee has carefully read this
      Agreement in its entirety, fully understands its provisions and its
      final and binding effect, and that Employee is signing this
      Agreement voluntarily.

IN WITNESS WHEREOF, the parties have duly executed and delivered this
Agreement as of _________________.

         WHEREAS, UCB and Cytec are parties to a Stock and Asset Purchase
Agreement dated as of October 1, 2004 (as amended from time to time the "UCB

and the Contracts; and

         WHEREAS, Solutia is willing to assume and consent to the assignment
of the Contracts, subject to the terms and conditions set forth herein.

         NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties hereto agree as follows:

         1.       UCB will pay or cause one of more of its affiliates to pay
                  Solutia an aggregate of $4,500,000 USD (the "Initial
                  Payment") on or prior to December 31, 2004 on account of
                  one or more liabilities or obligations of any type,
                  whether accrued, contingent or otherwise, to Solutia not
                  otherwise expressly waived under this Agreement
                  (collectively, the "Obligations"). Each of UCB, SSI, SSSA
                  and

                                     4

                  Solutia agree that, except as otherwise set forth
                  herein, Cytec, and only Cytec, is authorized to designate
                  which Obligations the Initial Payment shall be applied
                  against, and none of UCB, SSI, SSSA or Solutia will make
                  any designation as to which Obligations the Initial
                  Payment will be applied against. Notwithstanding the
                  foregoing, Solutia agrees that in the event that the UCB
                  SAPA is terminated, UCB shall have the right to designate
                  which Obligations the Initial Payment will be applied
                  against (including Obligations which would have been
                  waived hereunder if the UCB SAPA had not been terminated)
                  and Solutia shall not make any designation as to which
                  Obligations the Initial Payment will be applied against.
                  Promptly after it designates which Obligations the Initial
                  Payment will be applied against, Cytec or UCB as the case
                  may be, will notify Solutia of such designations. As
                  between Cytec and UCB, Cytec agrees that it may designate
                  only one or more of the Obligations described in Schedule
                  3.7(f) to the UCB SAPA as Obligations against which the
                  payment contemplated by this paragraph 1 shall be applied
                  and that it will make any such designation effective as of
                  the closing of the transactions contemplated by the UCB
                  SAPA (the "UCB Closing").

         2.       In contemplation of this Agreement, UCB has paid or caused
                  one or more of its affiliates to pay SOCAN $3,948,059 CAD
                  and has released or caused one or more of its affiliates
                  to release $800,000 CAD to SOCAN from the working fund
                  established under the LaSalle Toll Agreement in
                  satisfaction of all past due obligations under the LaSalle
                  Toll Agreement, consisting of $899,757 CAD for capital
                  expenditures made during 2003 and 2004 and $887,583 CAD
                  for overdue

                                     5

                  Service Fees plus $620,207 CAD VAT on these amounts and
                  $2,340,512 CAD for January and February 2004 invoices.
                  UCB and SOCAN acknowledge and agree that the $800,000
                  CAD released to SOCAN from the working fund represents
                  the amounts in excess of the working fund balance
                  currently required under the LaSalle Toll Agreement and
                  that the remaining $200,000 CAD in funds previously
                  advanced by UCB or its affiliates to the working fund
                  will remain in the working fund unless and until an
                  evaluation of monthly expenditures indicates a reduction
                  is appropriate. UCB will pay or cause one or more of its
                  affiliates to pay Solutia on or before December 31, 2004
                  an aggregate of $141,526 CAD, representing capital
                  expenditures under Section 3.8(a) of the LaSalle Toll
                  Agreement.

         3.       Solutia agrees, subject to approval of the Bankruptcy
                  Court having authority over its bankruptcy case (the
                  "Bankruptcy Court"), and effective upon the UCB Closing,
                  to amend, in accordance with paragraphs 6 through 8 of
                  this Agreement, and assume the following contracts
                  pursuant to Section 365 of the U.S. Bankruptcy Code (as
                  amended, the "Assumed Contracts"):

                    (i)      Lease and Manufacturing Agreement;
                    (ii)     Lab Services Agreement;
                    (iii)    Laboratory Lease and Access Agreement;
                    (iv)     DME Sales Contract;
                    (v)      Trademark Exclusive License Agreement;
                    (vi)     Ethyl Acetate Sales Contract;
                    (vii)    Adipic Acid Sales Contract; and
                    (viii)   Intellectual Property License Agreement.

                                     6

         4.       Effective as of the later of the effective date of the
                  Court Approval, as defined in paragraph 5 below, and the
                  UCB Closing, the parties acknowledge that Solutia owes UCB

                  and that the Cure Amount is the total amount payable by

                  Upon receipt of Court Approval, defined in paragraph 5
                  below, and Solutia's satisfaction of the Cure Amount, UCB,
                  SSI, SSSA and Cytec shall be forever barred and enjoined
                  from asserting against Solutia or its affiliates any
                  defaults, claims, interest or other default penalties
                  under the Assumed Contracts arising before the date of
                  this Agreement except for any obligations pursuant to the
                  Assumed Contracts that become due after the date of this
                  Agreement, including obligations pursuant to

                  including, without limitation, authorization for the
                  amendment and assumption of the Assumed Contracts and the

                  Bankruptcy Court enters one or more related orders in
                  connection therewith, the "Court Approval"). Solutia shall
                  use its reasonable best efforts to obtain the Court
                  Approval by February 21, 2005. In the

                  modification, vacation, stay, rehearing or reargument
                  shall be filed with respect to any such order), Solutia
                  shall cooperate with UCB in taking such reasonable steps,
                  and causing its affiliates to take such reasonable steps,
                  diligently, to defend against such appeal, petition or
                  motion and Solutia shall use, and shall cause its
                  affiliates to use, its and their respective reasonable
                  efforts to obtain an expedited resolution of any such
                  appeal, petition or motion.

                  SSI, SSSA or Solutia will make any designation as to which

                  be applied against, Cytec will notify Solutia of such
                  designations. As between Cytec and UCB, Cytec agrees that
                  it may designate only one or more of the Obligations

                  Obligations against which the payment contemplated by this
                  paragraph 11 shall be applied and that it will make any
                  such designation effective as of the UCB Closing.

                  other transfer by UCB or its affiliates, including any
                  deemed assignment or deemed transfer as a result of a
                  change in control of any of UCB's affiliates on their sale
                  to Cytec or one of its affiliates, of any and all of their
                  rights and obligations under the Contracts to Cytec
                  Industries Inc. or any of Cytec's affiliates. Each of
                  Solutia and SOCAN hereby waives any and all rights it may
                  have under any provision of any of the Contracts to the
                  extent such provision could be read to prohibit the UCB
                  Closing or to terminate or permit Solutia or SOCAN or any
                  of their affiliates to terminate any of the Contracts, or
                  to otherwise cease to perform or modify its performance of
                  any terms or conditions of such Contract, in connection

         13.      Each of Solutia and SOCAN hereby agree that to the extent
                  it has the right under a Contract to consent to the
                  assignment or other transfer by Cytec or any of its
                  affiliates, including any deemed assignment or deemed
                  transfer as a result of a change in control of any of
                  Cytec's affiliates or their sale to any entity that
                  purchases the amino resins business from Cytec and its
                  affiliates, of any or all of its rights and obligations
                  under the Contracts, such consent shall not be
                  unreasonably withheld. For purposes of this paragraph
                  only, it is agreed that

                                     13

                  Solutia will not be deemed to have reasonably withheld its
                  consent unless it would, after giving effect to any guarantees
                  of Cytec in connection with such consent, suffer a material
                  detriment with respect to such Contract as a result of the
                  assignment of such Contract to the proposed assignee.
                  Except for any right of Solutia or SOCAN to consent to the
                  assignment of a Contract, each of Solutia and SOCAN hereby
                  waives any and all rights it may have under any provision
                  of any of the Contracts to the extent such provision could
                  be read to prohibit Cytec or any of its affiliates from
                  disposing of all or any part of the amino resins business
                  to be transferred to Cytec by UCB pursuant to the UCB SAPA
                  or to terminate or permit Solutia or SOCAN or any of their
                  affiliates to terminate any of the Contracts, or to
                  otherwise cease to perform or modify its performance of
                  any terms or conditions of such Contract, in connection
                  with or as a result of any disposition by Cytec or any of
                  its affiliates of all or any part of the amino resins
                  business to be transferred to Cytec by UCB pursuant to the
                  UCB SAPA. In case at any time after the any assignment or
                  transfer by Cytec or any of its affiliates of any of their
                  respective rights under any Contract in accordance with
                  the foregoing any further action is reasonably necessary
                  to carry out the purposes of this Agreement, the proper
                  officers of Cytec, Solutia and SOCAN shall take any such
                  reasonably necessary action, including, without
                  limitation, Solutia and/or SOCAN entering into one or more
                  agreements, on terms no less favorable to Solutia or SOCAN
                  than the Contracts, with any third party acquirer of the
                  amino resins business to evidence the effects of the
                  partial assignment or transfer of such Contracts.
