appointment, an authenticating agent may authenticate the Notes whenever the
Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent. An authenticating agent has the
same rights as an Agent to deal with the Company and Affiliates of the Company.
Each Paying Agent is designated as an authenticating agent for purposes of this
Indenture.

          The Notes shall be issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof.

SECTION 2.04.  REGISTRAR AND PAYING AGENT.

          The Company shall maintain an office or agency where Notes may be
presented for registration of transfer or for exchange (the "REGISTRAR"), and an
office or agency where Notes may be presented for payment (the "PAYING AGENT")
and an office or agency where notices and demands to or upon the Company, if
any, in respect of the Notes and this Indenture may be served. The Registrar
shall keep a register of the Notes and of their transfer and exchange. The
Company may have one or more additional Paying Agents. The term "Paying Agent"
includes any additional Paying Agent. Neither the Company nor any Affiliate
thereof may act as Paying Agent.

          The Company shall enter into an appropriate agency agreement, which
shall incorporate the provisions of the TIA, with any Agent that is not a party
to this Indenture. The agreement shall implement the provisions of this
Indenture that relate to such Agent. The Company shall notify the Trustee of the
name and address of any such Agent. If the Company fails to maintain a Registrar
or Paying Agent, or fails to give the foregoing notice, the Trustee shall act as
such and shall be entitled to appropriate compensation in accordance with
Section 7.07.

          The Company initially appoints the Trustee as Registrar, Paying Agent
and Agent for service of notices and demands in connection with the Notes and
this Indenture.

SECTION 2.05.  PAYING AGENT TO HOLD MONEY IN TRUST.

          Each Paying Agent shall hold in trust for the benefit of the
Noteholders or the Trustee all money held by the Paying Agent for the payment of
principal of or premium or interest on the Notes (whether such money has been
paid to it by the Company or any other obligor on the Notes or the Subsidiary
Guarantors), and the Company and the Paying Agent shall notify the Trustee of
any default by the Company (or any other obligor on the Notes) in making any
such payment. Money held in trust by the Paying Agent need not be segregated
except as required by law and in no event shall the Paying Agent be liable for
any interest on any money received by it hereunder. The Company at any time may
require the Paying Agent to pay all money held by it to the Trustee and account
for any funds disbursed and the Trustee may at any time during the continuance
of any Event of Default specified in Section 6.01(1) or (2), upon written
request to the Paying Agent, require such Paying Agent to pay forthwith all
money so held by it to the Trustee and to account for any funds disbursed. Upon
making such payment, the Paying Agent shall have no further liability for the
money delivered to the Trustee.

SECTION 2.06.  NOTEHOLDER LISTS.

          The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
the Noteholders. If the Trustee is not the Registrar, the Company shall furnish
to the Trustee at least five Business Days before each Interest Payment Date,
and at such other times as the Trustee may request in writing, a list in such
form and as of such date as the Trustee may reasonably require of the names and
addresses of the Noteholders.

SECTION 2.07.  TRANSFER AND EXCHANGE.

          Subject to Sections 2.16 and 2.17, when Notes are presented to the
Registrar with a request from the Holder of such Notes to register a transfer or
to exchange them for an equal principal amount of Notes of other authorized
denominations, the Registrar shall register the transfer as requested. Every
Note presented or surrendered for registration of transfer or exchange shall be
duly endorsed or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Registrar, duly executed by the Holder
thereof or his attorneys duly authorized in writing. To permit registrations of
transfers and exchanges, the Company shall issue and execute and the Trustee
shall authenticate new Notes (and the Subsidiary Guarantors shall execute the
guarantee thereon) evidencing such transfer or exchange at the Registrar's
request. No service charge shall be made to the Noteholder for any registration
of transfer or exchange. The Company may require from the Noteholder payment of
a sum sufficient to cover any transfer taxes or other governmental charge that
may be imposed in relation to a transfer or exchange, but this provision shall
not apply to any exchange pursuant to Section 2.11, 3.06, 4.08, 4.12 or 8.05 (in
which events the Company shall be responsible

<Page>

                                      -35-

for the payment of such taxes). The Registrar shall not be required to exchange
or register a transfer of any Note for a period of 15 days immediately preceding
the mailing of notice of redemption of Notes to be redeemed or of any Note
selected, called or being called for redemption except the unredeemed portion of
any Note being redeemed in part.

          Any Holder of the Global Note shall, by acceptance of such Global
Note, agree that transfers of the beneficial interests in such Global Note may
be effected only through a book entry system maintained by the Holder of such
Global Note (or its agent), and that ownership of a beneficial interest in the
Global Note shall be required to be reflected in a book entry.

          Except as expressly provided herein, neither the Trustee nor the
Registrar shall have any duty to monitor the Company's compliance with or have
any responsibility with respect to the Company's compliance with any Federal or
state securities laws.

SECTION 2.08.  REPLACEMENT NOTES.

          If a mutilated Note is surrendered to the Registrar or the Trustee, or
if the Holder of a Note claims that the Note has been lost, destroyed or
wrongfully taken, the Company shall issue and the Trustee shall authenticate a
replacement Note (and the Subsidiary Guarantors shall execute the guarantee
thereon) if the Holder of such Note furnishes to the Company and the Trustee
evidence reasonably acceptable to them of the ownership and the destruction,
loss or theft of such Note and if the requirements of Section 8-405 of the New
York Uniform Commercial Code as in effect on the date of this Indenture are met.
If required by the Trustee or the Company, an indemnity bond shall be posted,
sufficient in the judgment of all to protect the Company, the Subsidiary
Guarantors, the Trustee or any Paying Agent from any loss that any of them may
suffer if such Note is replaced. The Company may charge such Holder for the
Company' reasonable out-of-pocket expenses in replacing such Note and the
Trustee may charge the Company for the Trustee's expenses (including, without
limitation, attorneys' fees and disbursements) in replacing such Note. Every
replacement Note shall constitute a contractual obligation of the Company.

SECTION 2.09.  OUTSTANDING NOTES.

          The Notes outstanding at any time are all Notes that have been
authenticated by the Trustee except for (a) those canceled by it, (b) those
delivered to it for cancellation, (c) to the extent set forth in Sections 9.01
and 9.02, on or after the date on which the conditions set forth in Section 9.01
or 9.02 have been satisfied, those Notes theretofore authenticated and delivered
by the Trustee hereunder and (d) those described in this Section 2.09 as not
outstanding. Subject to Section 2.10, a Note does not cease to be outstanding
because the Company or one of its Affiliates holds the Note.

<Page>

                                      -36-

          If a Note is replaced pursuant to Section 2.08, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser in whose hands such Note is a
legal, valid and binding obligation of the Company.

          If the Paying Agent holds, in its capacity as such, on any Maturity
Date, money sufficient to pay all accrued interest and principal with respect to
the Notes payable on that date and is not prohibited from paying such money to
the Holders thereof pursuant to the terms of this Indenture, then on and after
that date such Notes cease to be outstanding and interest on them ceases to
accrue.

SECTION 2.10.  TREASURY NOTES.

          In determining whether the Holders of the required principal amount of
Notes have concurred in any declaration of acceleration or notice of default or
direction, waiver or consent or any amendment, modification or other change to
this Indenture, Notes owned by the Company or any other Affiliate of the Company
shall be disregarded as though they were not outstanding, except that for the
purposes of determining whether the Trustee shall be protected in relying on any
such direction, waiver or consent or any amendment, modification or other change
to this Indenture, only Notes as to which a Responsible Officer of the Trustee
has actually received an Officers' Certificate stating that such Notes are so
owned shall be so disregarded. Notes so owned which have been pledged in good
faith shall not be disregarded if the pledgee established to the satisfaction of
the Trustee the pledgee's right so to act with respect to the Notes and that the
pledgee is not an Issuer, a Subsidiary Guarantor, any other obligor on the Notes
or any of their respective Affiliates.

SECTION 2.11.  TEMPORARY NOTES.

          Until definitive Notes are prepared and ready for delivery, the
Company may prepare and the Trustee shall authenticate temporary Notes.
Temporary Notes shall be substantially in the form of definitive Notes but may
have variations that the Company considers appropriate for temporary Notes.
Without unreasonable delay, the Company shall prepare and the Trustee shall
authenticate definitive Notes in exchange for temporary Notes. Until such
exchange, temporary Notes shall be entitled to the same rights, benefits and
privileges as definitive Notes.

SECTION 2.12.  CANCELLATION.

          The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Notes surrendered to them for registration of transfer, exchange or payment.
The Trustee shall cancel all Notes surrendered for registration of transfer,
exchange, payment, replacement or cancellation and shall (subject to the
record-retention requirements of the Exchange Act) dispose of such canceled

<Page>

                                      -37-

Notes in its customary manner. The Company may not reissue or resell, or issue
new Notes to replace, Notes that the Company has redeemed or paid, or that have
been delivered to the Trustee for cancellation.

SECTION 2.13.  DEFAULTED INTEREST.

          If the Company defaults on a payment of interest on the Notes, it
shall pay the defaulted interest, plus (to the extent permitted by law) any
interest payable on the defaulted interest, in accordance with the terms hereof,
to the Persons who are Noteholders on a subsequent special record date, which
date shall be at least five Business Days prior to the payment date. The Company
shall fix such special record date and payment date in a manner satisfactory to
the Trustee. At least 10 days before such special record date, the Company shall
mail to each Noteholder a notice that states the special record date, the
payment date and the amount of defaulted interest, and interest payable on
defaulted interest, if any, to be paid. The Company may make payment of any
defaulted interest in any other lawful manner not inconsistent with the
requirements (if applicable) of any securities exchange on which the Notes may
be listed and, upon such notice as may be required by such exchange, if, after
written notice given by the Company to the Trustee of the proposed payment
pursuant to this sentence, such manner of payment shall be deemed practicable by
the Trustee.

SECTION 2.14.  CUSIP NUMBER.

          The Company in issuing the Notes may use a "CUSIP" number, and if so,
such CUSIP number shall be included in notices of redemption or exchange as a
convenience to Holders; PROVIDED that any such notice may state that no
representation is made as to the correctness or accuracy of the CUSIP number
printed in the notice or on the Notes, and that reliance may be placed only on
the other identification numbers printed on the Notes. The Company shall
promptly notify the Trustee of any such CUSIP number used by the Company in
connection with the issuance of the Notes and of any change in the CUSIP number.

SECTION 2.15.  DEPOSIT OF MONEYS.

          Prior to 10:00 a.m., New York City time, on each Interest Payment Date
and Maturity Date, the Company shall have deposited with the Paying Agent in
immediately available funds money sufficient to make cash payments, if any, due
on such Interest Payment Date or Maturity Date, as the case may be, in a timely
manner which permits the Trustee to remit payment to the Holders on such
Interest Payment Date or Maturity Date, as the case may be. The principal and
interest on Global Notes shall be payable to the Depository or its nominee, as
the case may be, as the sole registered owner and the sole Holder of the Global
Notes represented thereby. The principal and interest on Physical Notes shall be
payable, either in person or by mail, at the office of the Paying Agent.

SECTION 2.16.  BOOK-ENTRY PROVISIONS FOR GLOBAL NOTES.

          (a)  Rule 144A Notes shall be represented by one or more Notes in
registered, global form without interest coupons (collectively, the "RESTRICTED
GLOBAL NOTE"). Regulation S Notes initially shall be represented by one or more
Notes in registered, global form without interest coupons (collectively, the
"REGULATION S GLOBAL NOTE," and, together with the Restricted Global Note and
any other global notes representing Notes, the "GLOBAL NOTES"). The Global Notes
shall bear legends as set forth in EXHIBIT D. The Global Notes initially shall
(i) be registered in the name of the Depository or the nominee of such
Depository, in each case for credit to an account of an Agent Member (or, in the
case of the Regulation S Global Notes, of Euroclear System ("EUROCLEAR") and
Clearstream Banking Luxembourg ("CLEARSTREAM")), (ii) be delivered to the
Trustee as custodian for such Depository and (iii) bear legends as set forth in
EXHIBIT B with respect to Restricted Global Notes and EXHIBIT C with respect to
Regulation S Global Notes.

          Members of, or direct or indirect participants in, the Depository
("AGENT MEMBERS") shall have no rights under this Indenture with respect to any
Global Note held on their behalf by the Depository, or the Trustee as its
custodian, or under the Global Notes, and the Depository may be treated by the
Company, the Trustee and any agent of the Company or the Trustee as the absolute
owner of the Global Note for all purposes whatsoever. Notwithstanding the
foregoing, nothing herein shall prevent the Company, the Trustee or any agent of
the Company or the Trustee from giving effect to any written certification,
proxy or other authorization furnished by the Depository or impair, as between
the Depository and its Agent Members, the operation of customary practices
governing the exercise of the rights of a Holder of any Note.

          (b)  Transfers of Global Notes shall be limited to transfer in whole,
but not in part, to the Depository, its successors or their respective Interests
of beneficial owners in the Global Notes may be transferred or exchanged for
Physical Notes in accordance with the rules and procedures of the Depository and
the provisions of Section 2.17. In addition, a Global Note shall be exchangeable
for Physical Notes if (i) the Depository (x) notifies the Company that it is
unwilling or unable to continue as depository for such Global Note and the
Company thereupon fails to appoint a successor depository or (y) has ceased to
be a clearing agency registered under the Exchange Act, (ii) the Company, at its
option, notifies the Trustee in writing that it elects to cause the issuance of
such Physical Notes or (iii) there shall have occurred and be continuing an
Event of Default with respect to the Notes. In all cases, Physical Notes
delivered in exchange for any Global Note or beneficial interests therein shall
be registered in the names, and issued in any approved denominations, requested
by or on behalf of the Depository (in accordance with its customary procedures).

<Page>

                                      -39-

          (c)  In connection with any transfer or exchange of a portion of the
beneficial interest in any Global Note to beneficial owners pursuant to
paragraph (b), the Registrar shall (if one or more Physical Notes are to be
issued) reflect on its books and records the date and a decrease in the
principal amount of the Global Note in an amount equal to the principal amount
of the beneficial interest in the Global Note to be transferred, and the Company
shall execute, and the Trustee shall upon receipt of a written order from the
Company authenticate and make available for delivery, one or more Physical Notes
of like tenor and amount.

          (d)  In connection with the transfer of Global Notes as an entirety
to beneficial owners pursuant to paragraph (b), the Global Notes shall be deemed
to be surrendered to the Trustee for cancellation, and the Company shall
execute, and the Trustee shall authenticate and deliver, to each beneficial
owner identified by the Depository in writing in exchange for its beneficial
interest in the Global Notes, an equal aggregate principal amount of Physical
Notes of authorized denominations.

          (e)  Any Physical Note constituting a Restricted Note delivered in
exchange for an interest in a Global Note pursuant to paragraph (b), (c) or (d)
shall, except as otherwise provided by paragraphs (a)(i)(x) and (c) of Section
2.17, bear the Private Placement Legend or, in the case of the Regulation S
Global Note, the legend set forth in EXHIBIT C, in each case, unless the Company
determine otherwise in compliance with applicable law.

          (f)  On or prior to the 40th day after the later of the commencement
of the offering of the Notes represented by the Regulation S Global Note and the
issue date of such Notes (such period through and including such 40th day, the
"RESTRICTED PERIOD"), a beneficial interest in a Regulation S Global Note may be
transferred to a Person who takes delivery in the form of an interest in the
corresponding Restricted Global Note only upon receipt by the Trustee of a
written certification from the transferor to the effect that such transfer is
being made (i)(a) to a Person that the transferor reasonably believes is a
Qualified Institutional Buyer in a transaction meeting the requirements of Rule
144A or (b) pursuant to another exemption from the registration requirements
under the Securities Act which is accompanied by an Opinion of Counsel regarding
the availability of such exemption and (ii) in accordance with all applicable
securities laws of any state of the United States or any other jurisdiction.

          (g)  Beneficial interests in the Restricted Global Note may be
transferred to a Person who takes delivery in the form of an interest in the
Regulation S Global Note, whether before or after the expiration of the
Restricted Period, only if the transferor first delivers to the Trustee a
written certificate to the effect that such transfer is being made in accordance
with Regulation S or Rule 144 (if available) and that, if such transfer occurs
prior to the expiration of the Restricted Period, the interest transferred will
be held immediately thereafter through Euroclear or Clearstream.

<Page>

                                      -40-

          (h)  Any beneficial interest in one of the Global Notes that is
transferred to a Person who takes delivery in the form of an interest in another
Global Note shall, upon transfer, cease to be an interest in such Global Note
and become an interest in such other Global Note and, accordingly, shall
thereafter be subject to all transfer restrictions and other procedures
applicable to beneficial interests in such other Global Note for as long as it
remains such an interest.

          (i)  The Holder of any Global Note may grant proxies and otherwise
authorize any Person, including Agent Members and Persons that may hold
interests through Agent Members, to take any action which a Holder is entitled
to take under this Indenture or the Notes.

SECTION 2.17.  SPECIAL TRANSFER PROVISIONS.

          (a)  TRANSFERS TO QIBS. The following provisions shall apply with
respect to the registration or any proposed registration of transfer of a Note
constituting a Restricted Note to a QIB (excluding transfers to Non-U.S.
Persons):

          (i)  the Registrar shall register the transfer if such transfer is
     being made by a proposed transferor who has checked the box provided for on
     such Holder's Note stating, or to a transferee who has advised the Company
     and the Registrar in writing, that it is purchasing the Note for its own
     account or an account with respect to which it exercises sole investment
     discretion and that it and any such account is a QIB within the meaning of
     Rule 144A, and is aware that the sale to it is being made in reliance on
     Rule 144A and acknowledges that it has received such information regarding
     the Company as it has requested pursuant to Rule 144A or has determined not
     to request such information and that it is aware that the transferor is
     relying upon its foregoing representations in order to claim the exemption
     from registration provided by Rule 144A; and

          (ii) if the proposed transferee is an Agent Member, and the Notes to
     be transferred consist of Physical Notes which after transfer are to be
     evidenced by an interest in the Global Note, upon receipt by the Registrar
     of instructions given in accordance with the Depository's and the
     Registrar's procedures, the Registrar shall reflect on its books and
     records the date and an increase in the principal amount of the Global Note
     in an amount equal to the principal amount of the Physical Notes to be
     transferred, and the Trustee shall cancel the Physical Notes so
     transferred.

          (b)  PRIVATE PLACEMENT LEGEND. Upon the registration of transfer,
exchange or replacement of Notes not bearing the Private Placement Legend, the
Registrar shall deliver

<Page>

                                      -41-

Notes that do not bear the Private Placement Legend. Upon the registration of
transfer, exchange or replacement of Notes bearing the Private Placement Legend,
the Registrar shall deliver only Notes that bear the Private Placement Legend
unless (i) there is delivered to the Registrar an Opinion of Counsel reasonably
satisfactory to the Company and the Trustee to the effect that neither such
legend nor the related restrictions on transfer are required in order to
maintain compliance with the provisions of the Securities Act or (ii) such Note
has been sold pursuant to an effective registration statement under the
Securities Act and the Registrar has received an Officers' Certificate from the
Company to such effect.

          (c)  GENERAL. By its acceptance of any Note bearing the Private
Placement Legend, each Holder of such Note acknowledges the restrictions on
transfer of such Note set forth in this Indenture and in the Private Placement
Legend and agrees that it will transfer such Note only as provided in this
Indenture.

          The Registrar shall retain for a period of two years copies of all
letters, notices and other written communications received pursuant to Section
2.16 or this Section 2.17. The Company shall have the right to inspect and make
copies of all such letters, notices or other written communications at any
reasonable time upon the giving of reasonable notice to the Registrar.

SECTION 2.18.  COMPUTATION OF INTEREST.

          Interest on the Notes shall be computed on the basis of a 360-day year
of twelve 30-day months and actual days elapsed.

                                  ARTICLE THREE

                                   REDEMPTION

SECTION 3.01.  ELECTION TO REDEEM; NOTICES TO TRUSTEE.

          If the Company elects to redeem Notes pursuant to paragraph 5 of the
Notes, at least 35 days prior to the Redemption Date (unless a shorter notice
shall be agreed to in writing by the Trustee) but not more than 65 days before
the Redemption Date, the Company shall notify the Trustee in writing of the
Redemption Date, the principal amount of Notes to be redeemed and the redemption
price, and deliver to the Trustee an Officers' Certificate stating that such
redemption will comply with the conditions contained in paragraph 5 of the
Notes. Notice given to the Trustee pursuant to this Section 3.01 may not be
revoked after the time that notice is given to Noteholders pursuant to Section
3.03.

                                      -42-

SECTION 3.02.  SELECTION BY TRUSTEE OF NOTES TO BE REDEEMED.

          The Trustee shall select the Notes to be redeemed, if the Notes are
listed on a national securities exchange, in accordance with the rules of such
exchange or, if the Notes are not so listed, either on a PRO RATA basis or by
lot, or such other method as the Trustee shall deem fair and appropriate;
PROVIDED that, in the case of a redemption pursuant to paragraph 5(a) of the
Notes, the Trustee shall select the Notes only on a PRO RATA basis or on as
nearly a PRO RATA basis as is practicable (subject to procedures of the
Depository). The Trustee shall promptly notify the Company of the Notes selected
for redemption and, in the case of any Notes selected for partial redemption,
the principal amount thereof to be redeemed. The Trustee may select for
redemption portions of the principal of the Notes that have denominations larger
than $1,000. Notes and portions thereof the Trustee selects shall be redeemed in
amounts of $1,000 or whole multiples of $1,000. For all purposes of this
Indenture unless the context otherwise requires, provisions of this Indenture
that apply to Notes called for redemption also apply to portions of Notes called
for redemption.

SECTION 3.03.  NOTICE OF REDEMPTION.

          At least 30 days, and no more than 60 days, before a Redemption Date,
the Company shall mail, or cause to be mailed, a notice of redemption by
first-class mail to each Holder of Notes to be redeemed at his or her last
address as the same appears on the registry books maintained by the Registrar
pursuant to Section 2.04.

          The notice shall identify the Notes to be redeemed (including the
CUSIP numbers thereof) and shall state:

          (1)  the Redemption Date;

          (2)  the redemption price and the amount of premium and accrued
     interest to be paid;

          (3)  if any Note is being redeemed in part, the portion of the
     principal amount of such Note to be redeemed and that, after the Redemption
     Date and upon surrender of such Note, a new Note or Notes in principal
     amount equal to the unredeemed portion will be issued;

          (4)  the name and address of the Paying Agent;

          (5)  that Notes called for redemption must be surrendered to the
     Paying Agent to collect the redemption price;

<Page>

                                      -43-

          (6)  that unless the Company defaults in making the redemption
     payment, interest on Notes called for redemption ceases to accrue on and
     after the Redemption Date;

          (7)  that paragraph 5 of the Notes is the provision of the Notes
     pursuant to which the redemption is occurring; and

          (8)  the aggregate principal amount of Notes that are being
     redeemed.

          At the Company's written request made at least five Business Days
prior to the date on which notice is to be given, the Trustee shall give the
notice of redemption in the Company's name and at the Company's sole expense.

SECTION 3.04.  EFFECT OF NOTICE OF REDEMPTION.

          Once the notice of redemption described in Section 3.03 is mailed,
Notes called for redemption become due and payable on the Redemption Date and at
the redemption price, including any premium, plus interest accrued to the
Redemption Date. Upon surrender to the Paying Agent, such Notes shall be paid at
the redemption price, including any premium, plus interest accrued to the
Redemption Date; PROVIDED that if the Redemption Date is after a regular record
date and on or prior to the Interest Payment Date, the accrued interest shall be
payable to the Holder of the redeemed Notes registered on the relevant record
date; and PROVIDED, FURTHER, that if a Redemption Date is a Legal Holiday,
payment shall be made on the next succeeding Business Day and no interest shall
accrue for the period from such Redemption Date to such succeeding Business Day.

SECTION 3.05.  DEPOSIT OF REDEMPTION PRICE.

          On or prior to 10:00 A.M., New York City time, on each Redemption
Date, the Company shall deposit with the Paying Agent in immediately available
funds money sufficient to pay the redemption price of, including premium, if
any, and accrued interest on all Notes to be redeemed on that date other than
Notes or portions thereof called for redemption on that date which have been
delivered by the Company to the Trustee for cancellation.

          On and after any Redemption Date, if money sufficient to pay the
redemption price of, including premium, if any, and accrued interest on Notes
called for redemption shall have been made available in accordance with the
immediately preceding paragraph, the Notes called for redemption will cease to
accrue interest and the only right of the Holders of such Notes will be to
receive payment of the redemption price of and, subject to the first proviso in
Section 3.04, accrued and unpaid interest on such Notes to the Redemption Date.
If any Note surrendered for redemption shall not be so paid, interest will be
paid, from the Redemption Date until such redemption payment is made, on the
unpaid principal of the Note and any interest

<Page>

                                      -44-

not paid on such unpaid principal, each case at the rate and in the manner
provided in the Notes.

SECTION 3.06.  NOTES REDEEMED IN PART.

          Upon surrender of a Note that is redeemed in part, the Trustee shall
authenticate for the Holder thereof a new Note equal in principal amount to the
unredeemed portion of the Note surrendered.

SECTION 3.07.  SPECIAL MANDATORY REDEMPTION; NOTICES TO TRUSTEE AND SECURITIES
               INTERMEDIARY.

          If the Solutia Assumption has not occurred on or before the Deadline
(the "SPECIAL REDEMPTION TRIGGER"), the Company will promptly notify the Trustee
thereof and deliver to the Trustee an Officers' Certificate stating that such
redemption will comply with the conditions contained in paragraph 6 of the Notes
and setting forth the Special Mandatory Redemption Price applicable to such
Special Mandatory Redemption. Simultaneously with the giving of such notice by
the Company to the Trustee, the Company shall notify the Securities Intermediary
thereof pursuant to Section 3(a) of the Escrow Agreement.

SECTION 3.08.  NOTICE OF SPECIAL MANDATORY REDEMPTION TO HOLDERS.

          Upon the occurrence of the Special Redemption Trigger, notice of the
Special Mandatory Redemption will be promptly mailed by first class mail by the
Company to each Holder of Notes at his or her last address as the same appears
on the registry books maintained by the Registrar pursuant to Section 2.04 and
to the Trustee and the Securities Intermediary.

          The notice shall state that all the Notes will be redeemed (including
the CUSIP numbers thereof) and shall state:

          (1)  the Special Mandatory Redemption Date;

          (2)  the Special Mandatory Redemption Price;

          (3)  the name and address of the Paying Agent;

          (4)  that Notes must be surrendered to the Paying Agent to collect the
     redemption price;

          (5)  that unless the Company defaults in making the redemption
     payment, interest on the Notes ceases to accrue on and after the Special
     Mandatory Redemption Date; and

<Page>

                                      -45-

          (6)  that paragraph 6 of the Notes is the provision pursuant to which
     the Notes are being redeemed.

SECTION 3.09.  EFFECT OF NOTICE OF SPECIAL MANDATORY REDEMPTION.

          Once the notice of redemption described in Section 3.08 is mailed, the
Notes will become due and payable on the Special Mandatory Redemption Date at
the Special Mandatory Redemption Price. Upon surrender to the Paying Agent, the
Notes shall be paid at the Special Mandatory Redemption Price; PROVIDED that if
the Special Mandatory Redemption Date is a Legal Holiday, payment shall be made
on the next succeeding Business Day and no interest shall accrue for the period
from such Special Mandatory Redemption Date to such succeeding Business Day.

SECTION 3.10.  DEPOSIT OF SPECIAL MANDATORY REDEMPTION PRICE.

          On or prior to 10:00 A.M., New York City time, on the Special
Mandatory Redemption Date, the Company shall direct the Securities Intermediary,
pursuant to Section 3(a) of the Escrow Agreement, to deposit with the Paying
Agent the applicable Special Mandatory Redemption Price.

          On and after the Special Mandatory Redemption Date, if money
sufficient to pay the applicable Special Mandatory Redemption Price shall have
been made available in accordance with the immediately preceding paragraph, the
Notes will cease to accrue interest and the only right of the Holders of the
Notes will be to receive payment of the Special Mandatory Redemption Price. If
any Note surrendered for redemption shall not be so paid, interest will be paid,
from the Special Mandatory Redemption Date until such redemption payment is
made, on the unpaid principal of the Note and any interest not paid on such
unpaid principal, in each case at the rate and in the manner provided in the
Notes.

                                  ARTICLE FOUR

SECTION 4.01.  PAYMENT OF NOTES.

          The Company shall pay the principal of and interest on the Notes on
the dates and in the manner provided in the Notes and this Indenture. An

sufficient to pay such installment.

<Page>

                                      -46-

          The Company shall pay interest on overdue principal (including
post-petition interest in a proceeding under any Bankruptcy Law), and overdue
interest, to the extent lawful, at the rate specified in the Notes.

SECTION 4.02.  MAINTENANCE OF OFFICE OR AGENCY.

          (a)  The Company shall maintain in the Borough of Manhattan, the City
of New York, an office or agency (which may be an office of the Trustee or an
affiliate of the Trustee or Registrar) where Notes may be surrendered for
registration of transfer or for exchange and where notices and demands to or
upon the Company in respect of the Notes and this Indenture may be served. The
Company shall give prompt written notice to the Trustee of the location, and any
change in the location, of such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee.

          (b)  The Company may also from time to time designate one or more
other offices or agencies where the Notes may be presented or surrendered for
any or all such purposes and may from time to time rescind such designations;
PROVIDED, HOWEVER, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency in the
Borough of Manhattan, the City of New York for such purposes. The Company shall
give prompt written notice to the Trustee of any such designation or rescission
and of any change in the location of any such other office or agency.

Trustee as one such office or agency of the Company in accordance with Section

Subsidiary, in accordance with the respective organizational documents (as the
same may be amended from time to time) of each Restricted Subsidiary and the
material rights (charter and statutory), and franchises of the Company and the
Restricted Subsidiaries; PROVIDED that the Company shall not be required to
preserve any such right, franchise, or the corporate, partnership or other
existence of any of its Restricted Subsidiaries if the Board of Directors of the
Company shall determine that the preservation thereof is no longer desirable in
the conduct of the business of the Company and its Restricted Subsidiaries taken
as a whole, and that the loss thereof is not adverse in any material respect to
the Holders.

the conduct of their respective businesses to be maintained and kept in good
condition, repair and working order (reasonable wear and tear excepted) and
supplied with all necessary equipment, and shall cause to be made all necessary
repairs, renewals, replacements, betterments and improvements thereto; PROVIDED,
HOWEVER, that nothing in this Section 4.04(a) shall prevent the Company or any
of its Restricted Subsidiaries from discontinuing the operation and maintenance
of any of such material properties if such discontinuance is, in the reasonable
judgment of the Company, desirable in the conduct of the business of the Company
and its Subsidiaries taken as a whole.

          (b)  The Company shall maintain insurance, and cause each of its
Restricted Subsidiaries to maintain insurance, with financially sound and
reputable insurers, with respect to such of its properties, against such risks,
casualties and contingencies and in such types and amounts as are consistent
with sound business practice, it being understood that this paragraph (b) shall
not prevent the use of deductible or excess loss insurance and shall not prevent
(i) the Company or any of its Subsidiaries from acting as a self-insurer or
maintaining insurance with another Subsidiary or Subsidiaries of the Company so
long as such action is consistent with sound business practice or (ii) the
Company from obtaining and owning insurance policies covering activities of its
Subsidiaries.

          (c)  The Company shall, and shall cause each of its Restricted
Subsidiaries to comply with all statutes, laws, ordinances or government rules
and regulations to which they are subject, non-compliance with which would
materially adversely affect the business, financial condition or results of
operations of the Company and its Restricted Subsidiaries taken as a whole.

SECTION 4.05.  WAIVER OF STAY, EXTENSION OR USURY LAWS.

          The Company and each of the Subsidiary Guarantors covenants (to the
extent that it may lawfully do so) that it shall not at any time insist upon, or
plead (as a defense or otherwise) or in any manner whatsoever claim or take the
benefit or advantage of, any stay or extension law or any usury law or other law
which would prohibit or forgive any of the Company and the Subsidiary Guarantors
from paying all or any portion of the principal of, premium, if any, and/or
interest on the Notes as contemplated herein, wherever enacted, now or at any
time hereafter in force, or which may affect the covenants or the performance of
this Indenture; and (to the extent that they may lawfully do so) each of the
Company and the Subsidiary Guarantors hereby expressly waives all benefit or
advantage of any such law, and covenants that it will not hinder, delay or
impede the execution of any power herein granted to

<Page>

                                      -48-

the Trustee, but will suffer permit the execution of every such power as though
no such law had been enacted.

SECTION 4.06.  COMPLIANCE CERTIFICATE.

          (a)  The Company shall deliver to the Trustee, within 120 days after
the end of each fiscal year, a certificate of an Officer (as enumerated by
Section 314(a)(4) of the TIA) stating that the Officer has conducted or
supervised a review of the activities of the Company and its Restricted
Subsidiaries and the Company's and its Restricted Subsidiaries' performance
under this Indenture during such fiscal year, and further stating, as to each
such Officer signing such certificate, that, to the best of such Officers'
knowledge, based upon such review, the Company has fulfilled all obligations
under this Indenture or, if there has been a Default under this Indenture that
is continuing, a description of the event and what action the Company and the
Subsidiary Guarantors are taking or propose to take with respect thereto.

          (b)  The Company will deliver to the Trustee, within 30 days after the
occurrence thereof, a certificate of an Officer detailing any continuing Default
of which such Officer is aware, its status and what action the Company is taking
or proposes to take with respect to such Default.

          (c)  The Company will provide written notice to the Trustee of any
change in its fiscal year.

          (d)  Solutia shall promptly notify the Trustee the first time the
Notes are rated Investment Grade; PROVIDED, HOWEVER, that the failure to deliver
such notice shall in no event be deemed a Default or an Event of Default.

SECTION 4.07.  TAXES.

          The Company shall, and shall cause each of its Restricted Subsidiaries
to, pay prior to delinquency all material taxes, assessments, and governmental
levies except as contested in good faith and by appropriate proceedings,

required to pay or discharge or cause to be paid or discharged any such tax,
assessment or governmental levies whose amount, applicability or validity is
being contested in good faith by appropriate proceedings or which is not of
material importance to the business, operations, financial conditions or results
of operations of the Company and its Subsidiaries, taken as a whole.

SECTION 4.08.  REPURCHASE AT THE OPTION OF HOLDERS UPON CHANGE OF CONTROL.

          (a)  Upon the occurrence of a Change of Control, each Holder of Notes
will have the right to require the Company to repurchase all or any part (equal
to $1,000 or an integral multiple thereof) of such Holder's Notes pursuant to
the offer described below (the "CHANGE OF CONTROL OFFER") at an offer price in
cash equal to 101% of the aggregate principal amount thereof plus accrued and
unpaid interest, if any, thereon to the date of purchase (the "CHANGE OF CONTROL

Change of Control (the "CHANGE OF CONTROL PAYMENT DATE"). Within 30 days
following any Change of Control, the Company will mail, or at the Company's

the Notes held by such Holder pursuant to the procedures specified in such
notice.

          (b)  Within 30 days following the date on which a Change of Control

registered address and, if given by the Company, the Trustee, which notice shall
govern the terms of the Change of Control Offer. The notice to the Holders shall
contain all instructions and materials necessary to enable such Holders to
tender Notes pursuant to the Change of Control Offer. Such notice shall state:

     (1)  that the Change of Control Offer is being made pursuant to this
          Section 4.08 and that all Notes validly tendered and not withdrawn
          will be accepted for payment;

     (2)  the Change of Control Payment and the Change of Control Payment Date
          (which shall be no earlier than 30 days nor later than 60 days from
          the date such notice is mailed, other than as may be required by law);

     (3)  that any Note not tendered will continue to accrue interest;

     (4)  that, unless the Company defaults in making payment therefor, any Note
          accepted for payment pursuant to the Change of Control Offer shall
          cease to accrue interest after the Change of Control Payment Date;

     (5)  that Holders electing to have a Note purchased pursuant to a Change of
          Control Offer will be required to surrender the Note, with the form
          entitled "Option of Holder to Elect Purchase" on the reverse of the
          Note completed, to the Paying Agent and Registrar for the Notes at the
          address specified in the notice prior to the close of business on the
          third Business Day prior to the Change of Control Payment Date;

<Page>

                                      -50-

     (6)  that Holders will be entitled to withdraw their election if the Paying
          Agent receives, not later than the second Business Day prior to the
          Change of Control Payment Date, a telegram, telex, facsimile
          transmission or letter setting forth the name of the Holder, the
          principal amount of the Notes the Holder delivered for purchase and a
          statement that such Holder is withdrawing its election to have such
          Note purchased;

     (7)  that Holders whose Notes are purchased only in part will be issued new
          Notes in a principal amount equal to the unpurchased portion of the
          Notes surrendered; PROVIDED, HOWEVER, that each Note purchased and
          each new Note issued shall be in a principal amount of $1,000 or
          integral multiples thereof; and

     (8)  the circumstances and relevant facts regarding such Change of Control.

          (c)  On the Change of Control Payment Date, the Company will, to the
extent lawful: (x) accept for payment all Notes or portions of Notes properly
tendered in the Change of Control Offer; (y) deposit with the Paying Agent an
amount equal to the Change of Control Payment for all Notes or portions of Notes
tendered; and (z) deliver or cause to be delivered to the Trustee the Notes so
accepted together with an Officers' Certificate stating the aggregate principal
amount of Notes or portions of Notes being purchased by the Company.

          (d)  The Paying Agent will promptly mail to each Holder of Notes
tendered the Change of Control Payment for them, and the Trustee will promptly
authenticate and mail (or cause to be transferred by book entry) to each Holder
a new Note equal in principal amount to any unpurchased portion of the Notes
surrendered, if any. Upon the payment of the Change of Control Payment, the
Trustee shall return the Notes purchased to the Company for cancellation. For
purposes of this Section 4.08, the Trustee shall act as the Paying Agent.

          (e)  Notwithstanding the foregoing, the Company will not be required
to make a Change of Control Offer, as provided above, if, in connection with or
in contemplation of any Change of Control, it or a third party has made an offer
to purchase (an "ALTERNATE OFFER") any and all Notes validly tendered at a cash
price equal to or higher than the Change of Control Payment and has purchased
all Notes properly tendered and not withdrawn in accordance with the terms of
such Alternate Offer.

          (f)  The Company will comply with the requirements of Rule 14e-1 under
the Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Notes pursuant to a Change of Control Offer. To the extent that
the provisions of any securities laws or regulations conflict with the
provisions of this Section 4.08, the Company shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its
obligations under the provisions of this Section 4.08 by virtue thereof.

SECTION 4.09.  LIMITATION ON INCURRENCE OF ADDITIONAL INDEBTEDNESS AND ISSUANCE
               OF PREFERRED STOCK.

          Prior to the Assumption Date, the Company will not incur any
Indebtedness (including Acquired Debt) or issue any Disqualified Stock, except
for the Notes.

          From and after the Assumption Date:

          (1)  the Company will not, and will not permit any of its Restricted
     Subsidiaries to, incur any Indebtedness (including Acquired Debt);

          (2)  the Company will not, and will not permit any of its Restricted
     Subsidiaries to, issue any Disqualified Stock (including Acquired

          (3)  the Company will not permit any of its Restricted Subsidiaries
     that are not Subsidiary Guarantors to issue any shares of Preferred Stock
     (including Acquired Preferred Stock);

PROVIDED, HOWEVER, that the Company and the Subsidiary Guarantors may incur
Indebtedness (including Acquired Debt) and the Company and the Subsidiary
Guarantors may issue shares of Disqualified Stock (including Acquired
Disqualified Stock) if the Fixed Charge Coverage Ratio for the Company's most
recently ended four full fiscal quarters for which financial statements have
been filed with the SEC pursuant to Section 4.18 immediately preceding the date
on which such additional Indebtedness is incurred or such Disqualified Stock is
issued would have been at least 2 to 1, determined on a PRO FORMA basis
(including a PRO FORMA application of the net proceeds therefrom), as if the
additional Indebtedness had been incurred or the Disqualified Stock had been
issued, as the case may be, at the beginning of such four-quarter period, with
any letters of credit and bankers' acceptances being deemed to have an aggregate
principal amount of Indebtedness equal to the maximum amount available
thereunder.

          The immediately preceding paragraph will not apply to:

     (i)       (I) the incurrence by the Company or any Subsidiary Guarantor of
     Indebtedness pursuant to the Credit Facility in an aggregate principal
     amount at any time outstanding not to exceed the lesser of (x) $800 million
     and (y) the aggregate amount of the Credit Facility as specified in the
     Assumption Documentation, less the aggregate principal amount of all
     mandatory repayments applied to (a) repay loans (other than revolving
     credit loans) outstanding thereunder or (b) permanently reduce the
     revolving credit commitments thereunder (and the corresponding guarantees
     of the Subsidiary Guarantors thereunder) and (II) the incurrence by any
     Foreign Subsidiary of Indebtedness pursuant to the Credit Facility in an
     aggregate principal amount not to exceed

<Page>

                                      -52-

     the aggregate principal amount of Indebtedness incurred by Foreign
     Subsidiaries under the Credit Facility on the Assumption Date; PROVIDED,
     HOWEVER, that if the Company or a Subsidiary Guarantor transfers any
     material assets to a Foreign Subsidiary that is a borrower under the Credit
     Facility, then, at the time of such transfer, there shall be deemed to be
     an incurrence of Indebtedness that is not permitted by this clause (i)(II)
     in the amount of Indebtedness that is outstanding under this clause (i)(II)
     at the time of such transfer;

     (ii)      the incurrence by the Company and the Subsidiary Guarantors of
     Indebtedness represented by the Notes (not including any Additional Notes)
     and Subsidiary Guarantees thereof, including any Exchange Securities issued
     for the Notes issued on the Issue Date;

     (iii)     the Existing Indebtedness of the Company and its Restricted
     Subsidiaries (other than Indebtedness of the type described in clause (i),
     (ii), (v), (ix) or (x) of this Section 4.09);

     (iv)      the incurrence by the Company or any of its Restricted
     Subsidiaries of any Permitted Refinancing in exchange for, or the Net
     Proceeds of which are used to extend, refinance, renew, replace, defease or
     refund, Indebtedness that was permitted to be incurred under (A) the Fixed
     Charge Coverage Ratio test set forth above or (B) clauses (ii) and (iii)
     above, clause (xi) below or this clause (iv);

     (v)       the incurrence by the Company or any of its Restricted
     Subsidiaries of intercompany Indebtedness between or among the Company and
     any of its Restricted Subsidiaries; PROVIDED, HOWEVER, that (i) if the
     Company or any Subsidiary Guarantor is the obligor on such Indebtedness,
     then (other than intercompany notes that constitute Collateral) such
     Indebtedness is expressly subordinated by its terms to the prior payment in
     full in cash of all Obligations with respect to the Notes or the Subsidiary
     Guarantee, as the case may be, and (ii) (A) any subsequent issuance or
     transfer of Capital Stock that results in any such Indebtedness being held
     by a Person other than the Company or a Restricted Subsidiary and (B) any
     sale or other transfer of any such Indebtedness to a Person that is not
     either the Company or a Restricted Subsidiary shall be deemed, in each
     case, to constitute a simultaneous incurrence of such Indebtedness that is
     not permitted by this clause (v) by the Company or such Restricted
     Subsidiary, as the case may be;

     (vi)      the incurrence by the Company or any Restricted Subsidiary of
     Hedging Obligations that are incurred for the purpose of (A) fixing or
     hedging interest rate or currency risk with respect to any fixed or
     floating rate Indebtedness that is permitted by this Indenture to be
     outstanding which is designed solely to protect the Company or any
     Restricted Subsidiary against fluctuations in foreign currency exchange
     rates; PROVIDED

<Page>

                                      -53-

     that such Hedging Obligation does not increase the principal amount of any
     such Indebtedness other than as a result of fluctuations in foreign
     currency exchange rates or interest rates or by reason of fees, indemnities
     and compensation payable thereunder or (B) managing fluctuations in the
     price or cost of energy, raw materials, manufactured products or related
     commodities; PROVIDED that such obligations are entered into for valid
     business purposes other than speculative purposes (as determined by the
     Company's or such Restricted Subsidiary's principal financial officer in
     the exercise of his or her good faith business judgment);

     (vii)     the issuance by any of the Company's Restricted Subsidiaries of
     shares of Preferred Stock to the Company or a Wholly Owned Restricted
     Subsidiary; PROVIDED that (A) any subsequent issuance or transfer of
     Capital Stock that results in such Preferred Stock being held by a Person
     other than the Company or a Wholly Owned Restricted Subsidiary or (B) the
     transfer or other disposition by the Company or a Wholly Owned Restricted
     Subsidiary of any such shares to a Person other than the Company or a
     Wholly Owned Restricted Subsidiary shall be deemed, in each case, to
     constitute an issuance of such Preferred Stock by such Subsidiary on such
     date that is not permitted by this clause (vii);

     (viii)    the incurrence by the Company or any of its Restricted
     Subsidiaries of Indebtedness represented by worker's compensation claims
     and other statutory or regulatory obligations, self-insurance obligations,
     tender, bid, performance, government contract, surety or appeal bonds,
     standby letters of credit and warranty and contractual service obligations
     of like nature, trade letters of credit or documentary letters of credit,
     in each case to the extent incurred in the ordinary course of business of
     the Company or such Restricted Subsidiary;

     (ix)      the incurrence of Indebtedness by Foreign Subsidiaries (not
     including Indebtedness incurred pursuant to clause (i)(II) above), the
     aggregate principal amount (or accreted value, as applicable) at any time
     outstanding and incurred in reliance upon this clause (ix), does not exceed
     $25 million;

     (x)       the Guarantee by the Company or any Subsidiary Guarantor of
     Indebtedness of the Company or a Restricted Subsidiary that was permitted
     to be incurred by another provision of this Section 4.09;

     (xi)      Acquired Debt or Acquired Disqualified Stock; PROVIDED that such
     Indebtedness or Disqualified Stock was not incurred in connection with or
     in contemplation of such Person becoming a Restricted Subsidiary; and
     PROVIDED FURTHER that immediately after giving effect to such incurrence,
     the Fixed Charge Coverage Ratio for the Company's most recently ended four
     full fiscal quarters for which financial statements have been filed with
     the SEC pursuant to Section 4.18 immediately preceding

<Page>

                                      -54-

     the date of such incurrence would have been at least 2 to 1, determined on
     a PRO FORMA basis (including giving PRO FORMA effect to the applicable
     transaction related thereto);

     (xii)     Indebtedness consisting of take-or-pay obligations contained in
     supply agreements entered into in the ordinary course of business;

     (xiii)    the incurrence by the Company and the Subsidiary Guarantors of
     Purchase Money Obligations and Capital Lease Obligations in an aggregate
     principal amount not to exceed $50 million at any one time outstanding;

     (xiv)     Indebtedness arising from agreements of the Company or a
     Restricted Subsidiary providing for indemnification, contribution, earnout,
     adjustment of purchase price or similar obligation, in each case, incurred
     or assumed in connection with the disposition of any business, assets or
     Capital Stock of a Restricted Subsidiary;

     (xv)      Indebtedness arising from the honoring by a bank or other
     financial institution of a check, draft or similar instrument drawn against
     insufficient funds in the ordinary course of business; PROVIDED, that such
     Indebtedness is extinguished within three business days of incurrence; and

     (xvi)     the incurrence by the Company or any Subsidiary Guarantor of
     Indebtedness or the issuance of Disqualified Stock, the aggregate principal
     amount (or accreted value, as applicable) or liquidation preference of
     which, together with all other Indebtedness and Disqualified Stock at the
     time outstanding and incurred in reliance on this clause (xvi), does not
     exceed $50 million.

          For purposes of determining compliance with this Section 4.09, in the
event that an item of Indebtedness or Preferred Stock meets the criteria of more
than one of the categories of permitted Indebtedness described in clauses (i)
through (xvi) above or is entitled to be incurred pursuant to the first
paragraph of this Section 4.09, the Company shall, in its sole discretion,
classify on the date of incurrence (and from time to time reclassify in whole or
in part) such item of Indebtedness or Preferred Stock in any matter that
complies with this Section 4.09 and such Indebtedness or Preferred Stock will be
treated as having been incurred pursuant to the clauses or the first paragraph
hereof, as the case may be, designated by the Company (PROVIDED that all
Indebtedness under the Credit Facility shall at all times be deemed to have been
incurred pursuant to clause (i) of this Section 4.09). The amount of
Indebtedness issued at a price which is less than the principal amount thereof
shall be equal to the amount of the liability in respect thereof determined in
accordance with GAAP.

SECTION 4.10.  LIMITATION ON RESTRICTED PAYMENTS.

          Prior to the Assumption Date, the Company will not make any Restricted
Payments (as defined below) or any Permitted Investments, except to the extent
necessary to consummate the Solutia Assumption, perform its obligations under
the Escrow Agreement and the transactions contemplated thereby, including any
Investments deemed to exist by virtue of the Escrow Agreement.

          From and after the Assumption Date, the Company will not, and will not
permit any of its Restricted Subsidiaries to, directly or indirectly:

          (1)  declare or pay any dividend or make any distribution on account
     of the Company's or any of its Restricted Subsidiaries' Capital Stock,
     other than:

                 (x)     dividends or distributions payable in Qualified Capital
          Stock of the Company, and

                 (y)     dividends or distributions payable to the Company or
          any Restricted Subsidiary of the Company;

          (2)  purchase, redeem or otherwise acquire or retire for value any
     Capital Stock of the Company, other than any such Capital Stock owned by
     the Company or any of its Restricted Subsidiaries;

          (3)  make any principal payment on, or purchase, redeem, defease or
     otherwise acquire or retire for value, any Subordinated Debt of the Company
     or any Restricted Subsidiary, other than Indebtedness owed to the Company
     or any Restricted Subsidiary, except, in each case, payment of interest or
     principal at Stated Maturity; or

          (4)  make any Restricted Investment

(all such payments and other actions set forth in clauses (1) through (4) above
(other than any exception thereto) being collectively referred to as "RESTRICTED
PAYMENTS"), unless, at the time of and after giving effect to such Restricted
Payment (the amount of any such Restricted Payment, if other than cash, shall be
the fair market value (as conclusively evidenced by a resolution of the Board of
Directors) of the asset(s) proposed to be transferred by the Company or such
Restricted Subsidiary, as the case may be, pursuant to such Restricted Payment):

          (a)  no Default or Event of Default shall have occurred and be
     continuing after giving effect thereto; and

          (b)  the Company would, at the time of such Restricted Payment and
     after giving PRO FORMA effect thereto as if such Restricted Payment had
     been made at the beginning

                                      -56-

     of the most recently ended four full fiscal quarters for which financial
     statements have been filed with the SEC pursuant to Section 4.18
     immediately preceding the date of such Restricted Payment, have been
     permitted to incur at least $1.00 of additional Indebtedness pursuant to
     the Fixed Charge Coverage Ratio test set forth in the first paragraph of
     Section 4.09; and

          (c)  such Restricted Payment, together with the aggregate of all other
     Restricted Payments made by the Company and its Restricted Subsidiaries on
     or after the Issue Date (excluding Restricted Payments permitted by clause
     (b), (d) or (e) of the next succeeding paragraph), is less than the sum,
     without duplication, of:

          (i)       50% of the Consolidated Net Income of the Company for the
          period (taken as one accounting period) from the Issue Date to the end
          of the Company's most recently ended fiscal quarter for which
          financial statements have been filed with the SEC pursuant to Section
          4.18 at the time of such Restricted Payment (or, if such Consolidated
          Net Income for such period is a deficit, less 100% of such deficit),
          PLUS

          (ii)      100% of the aggregate net cash proceeds received by the
          Company from the issue or sale after the Issue Date of Qualified
          Capital Stock of the Company or of debt securities of the Company or
          any of its Restricted Subsidiaries that have been converted into or
          exchanged for such Qualified Capital Stock of the Company, PLUS

          (iii)     to the extent that any Restricted Investment that was made
          after the Issue Date and was included in the calculation of aggregate
          Restricted Payments under this clause (c) is sold for cash or
          otherwise liquidated, repaid or otherwise reduced, including by way of
          dividend or distribution (to the extent not included in calculating
          Consolidated Net Income), for cash, the lesser of (A) the cash return
          with respect to such Restricted Investment (less the cost of
          disposition, if any) or (B) the initial amount of such Restricted
          Investment, PLUS

          (iv)      an amount equal to the sum of (A) the net reduction in
          Investments in Unrestricted Subsidiaries resulting from dividends,
          repayments of loans or other transfers of assets (to the extent not
          included in calculating Consolidated Net Income), in each case, to the
          Company or any Restricted Subsidiary from Unrestricted Subsidiaries
          and (B) the portion (proportionate to the Company's equity interest in
          such Subsidiary) of the fair market value of the net assets of an
          Unrestricted Subsidiary at the time such Unrestricted Subsidiary is
          designated a Restricted Subsidiary;

<Page>

                                      -57-

          PROVIDED, HOWEVER, that the foregoing sum shall not exceed, in the
          case of any Unrestricted Subsidiary, the amount of Restricted
          Investments previously made after the Issue Date by the Company or any
          Restricted Subsidiary in such Unrestricted Subsidiary that were
          included in the calculation above of aggregate Restricted Payments
          under this clause (c).

          The foregoing provisions of this Section 4.10 will not prohibit the
following Restricted Payments:

          (a)  the payment of any dividend within 90 days after the date of
     declaration thereof, if at said date of declaration such payment would have
     complied with the provisions of this Indenture;

          (b)  dividends or distributions by any Wholly-Owned Restricted
     Subsidiary of the Company payable to the Company or another Wholly-Owned
     Restricted Subsidiary of the Company;

          (c)  so long as no Default or Event of Default has occurred and is
     continuing, the payment of cash dividends on any series of Disqualified
     Stock issued after the Issue Date in an aggregate amount not to exceed the
     cash received by the Company since the Issue Date upon issuance of such
     Disqualified Stock;

          (d)  the redemption, repurchase, retirement or other acquisition of
     any Capital Stock of the Company, any Restricted Subsidiary or any Joint
     Venture (or the acquisition of all the outstanding Capital Stock of any
     Person that conducts no operations and has no assets or liabilities other
     than the ownership of Capital Stock in a Joint Venture) in exchange for, or
     out of the net cash proceeds of the substantially concurrent sale (other
     than to a Subsidiary or Joint Venture of the Company) of, Qualified Capital
     Stock of the Company; PROVIDED that the amount of any such net cash
     proceeds that are utilized for any such redemption, repurchase, retirement
     or other acquisition shall be excluded from (and shall not previously have
     been included in) clause (c)(ii) of the preceding paragraph;

          (e)  the defeasance, redemption or repurchase of Subordinated Debt
     with the net cash proceeds from an incurrence of Permitted Refinancing or
     in exchange for or out of the net cash proceeds from the substantially
     concurrent sale (other than to a Subsidiary or Joint Venture of the
     Company) of Qualified Capital Stock of the Company; PROVIDED that the
     amount of any such net cash proceeds that are utilized for any such
     redemption, repurchase, retirement or other acquisition shall be excluded
     from (and shall not previously have been included in) clause (c)(ii) of the
     preceding paragraph;

<Page>

                                      -58-

          (f)  the repurchase, redemption or other acquisition or retirement for
     value of any Capital Stock of the Company or any Subsidiary of the Company
     held by any member of the Company's (or any of its Subsidiaries')
     management pursuant to any management equity subscription agreement or
     stock option agreement; PROVIDED that the aggregate price paid for all such
     repurchased, redeemed, acquired or retired Capital Stock in reliance on
     this clause (f) shall not exceed $5 million in any calendar year;

          (g)  payments by the Company made pursuant to the Astaris Support
     Agreement as such agreement is in effect on the Issue Date or as such
     agreement may be amended, modified, supplemented or replaced, in whole or
     in part; PROVIDED that the aggregate amount of payments made in reliance on
     this clause (g) shall in no event exceed the maximum aggregate amount of
     payments required to be made by the Company after the Issue Date under the
     Astaris Support Agreement as in effect on the Issue Date;

          (h)  repurchases of shares of preferred stock of Solutia Management
     Company, Inc. in accordance with the terms of its stockholders agreement,
     dated as of December 29, 1998, in an amount not to exceed $1.5 million in
     the aggregate;

          (i)  Restricted Payments comprised of payments of dividends on, or
     repurchases of, the Company's common stock, in an aggregate amount not to
     exceed the lower of (x) $10 million per calendar year and (y) $0.04 per
     share; PROVIDED that no Default or Event of Default shall have occurred and
     be continuing after giving effect to such Restricted Payment;

          (j)  notwithstanding anything to the contrary contained herein,
     repurchases of Capital Stock deemed to occur upon the exercise of stock
     options, to the extent such repurchases represent a portion of the exercise
     price thereof or withholding of applicable taxes thereon and the purchase
     price, or applicable withholding taxes, for such repurchases is paid solely
     in Qualified Capital Stock; and

          (k)  additional Restricted Payments in an aggregate amount not to
     exceed $25 million.

          If the Company or any Restricted Subsidiary of the Company sells or
otherwise disposes of any Capital Stock of any direct or indirect Restricted
Subsidiary of the Company such that, after giving effect to any such sale or
disposition, such Person is no longer a Restricted Subsidiary of the Company,
the Company shall be deemed to have made an Investment on the date of any such
sale or disposition equal to the fair market value of the Capital Stock of such
Restricted Subsidiary not sold or disposed of in an amount determined as
provided in the first paragraph of this Section 4.10.

<Page>

                                      -59-

          Prior to the first time the Notes are rated Investment Grade, the
Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary
if such designation would not cause a Default. For purposes of making such
determination, all outstanding Investments by the Company and its Restricted
Subsidiaries in the Subsidiary so designated will be deemed to be Restricted
Payments at the time of such designation and will reduce the amount available
for Restricted Payments under the first paragraph of this Section 4.10 (except
to the extent such Investments were repaid to the Company or a Restricted
Subsidiary in cash). All such outstanding Investments will be deemed to
constitute Investments in an amount equal to the fair market value of such
Investments at the time of such designation, as conclusively determined by the
Board of Directors. Such designation will only be permitted if any such
Restricted Payment would be permitted at such time and if such Restricted
Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. In the
case of any designation by the Company of a Person as an Unrestricted Subsidiary
on the first day that such Person is a Subsidiary of the Company in accordance
with the provisions of this Indenture, such designation shall be deemed to have
occurred for all purposes of this Indenture simultaneously with, and
automatically upon, such Person becoming a Subsidiary.

SECTION 4.11.  LIMITATION ON LIENS.

          Prior to the Assumption Date, the Company will not, directly or
indirectly, create, incur, assume or otherwise cause or suffer to exist or
become effective any Lien of any kind upon any of its assets, now owned or
hereafter acquired, or upon any income or profits therefrom or assign any rights
to receive income therefrom, other than as contemplated by the Escrow Agreement.

          From and after the Assumption Date, the Company will not, and will not
permit any of its Restricted Subsidiaries to, directly or indirectly, create,
incur, assume or suffer to exist any Lien, except Permitted Liens, on any asset
now owned or hereafter acquired, or any income or profits therefrom, unless all
payments due under this Indenture and the Notes are secured on an equal and
ratable basis with the obligations so secured (or, if such obligations are
subordinated by their terms to the Notes or the Subsidiary Guarantees, prior to
the obligations so secured) until such time as such obligations are no longer
secured by a Lien.

SECTION 4.12.  LIMITATION ON ASSET SALES.

          (a)  Prior to the Assumption Date, the Company will not consummate an
Asset Sale except to the extent necessary to consummate the transactions
contemplated by the Escrow Agreement, including the Solutia Assumption and the
related release to Solutia of the Escrow Assets.

          From and after the Assumption Date, the Company will not, and will not
permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

<Page>

                                      -60-

          (i)       the Company and/or such Restricted Subsidiary, as the case
          may be, receives consideration at the time of such Asset Sale at least
          equal to the fair market value (as conclusively evidenced by an
          Officers' Certificate delivered to the Trustee or, if such Asset Sale
          involves aggregate consideration in excess of $20 million, a
          resolution of the Board of Directors that is set forth in an Officers'
          Certificate delivered to the Trustee) of the assets or Capital Stock
          issued or sold or otherwise disposed of,

          (ii)      at least 75% of the consideration therefor received by the
          Company and/or such Restricted Subsidiary is in the form of cash or
          Cash Equivalents, and

          (iii)     if such Asset Sale involves the transfer of Collateral, (a)
          it complies with the applicable provisions of the Security Documents
          and (b) all consideration received in such Asset Sale (including
          Additional Assets) shall, if applicable, be expressly made subject to
          the Lien under the Security Documents;

PROVIDED that the amount of (x) any liabilities (as shown on the Company's or
such Restricted Subsidiary's most recent balance sheet) of the Company or any
Restricted Subsidiary (other than Subordinated Debt) that are assumed by the
transferee of any such assets pursuant to a customary novation agreement that
releases the Company or such Restricted Subsidiary from further liability and
(y) any securities, notes or other obligations received by the Company or such
Restricted Subsidiary from such transferee, to the extent they are promptly
converted or monetized by the Company or such Restricted Subsidiary into cash
(to the extent of the cash received), shall be deemed to be cash for purposes of
this provision.

          Within 360 days after the receipt of any Net Proceeds from an Asset
Sale, the Company may apply such Net Proceeds, at its option:

          (a)  to permanently repay Applicable Pari Passu Indebtedness (and to
     correspondingly reduce commitments with respect thereto in the case of
     revolving borrowings); or

          (b)  to acquire Additional Assets (to the extent otherwise permitted
     by this Indenture) or make a capital expenditure, in each case, in a
     Permitted Business (or enter into a binding commitment for any such
     acquisition or expenditure); PROVIDED that such binding commitment shall be
     treated as a permitted application of Net Proceeds from the date of such
     commitment until and only until the earlier of (x) the date on which such
     expenditure or acquisition is consummated and (y) the 180th day following
     the expiration of the aforementioned 360 day period. If the acquisition or
     expenditure contemplated by such binding commitment is not consummated on
     or before such 180th day and the Company shall not have applied such Net
     Proceeds pursuant to

<Page>

                                      -61-

     clause (a) above on or before such 180th day, such commitment shall be
     deemed not to have been a permitted application of Net Proceeds at any
     time.

          Pending the final application of any such Net Proceeds, the Company
may temporarily reduce the revolving Indebtedness under the Credit Facility or
otherwise invest such Net Proceeds in any manner that is not prohibited by this
Indenture. Any Net Proceeds from Asset Sales that are not applied or invested as
provided in the first sentence of this paragraph will be deemed to constitute
"EXCESS PROCEEDS." On any date that the aggregate amount of Excess Proceeds
under this Indenture exceeds $25 million (an "ASSET SALE OFFER TRIGGER DATE"),
the Company will be required to make an offer to all Holders of Notes issued
under this Indenture (an "ASSET SALE OFFER") to purchase the maximum principal
amount of Notes and, if the Company is required to do so under the terms of any
other Indebtedness ranking PARI PASSU with such Notes ("OTHER INDEBTEDNESS"),
such other Indebtedness on a PRO RATA basis with the Notes that may be purchased
out of the Excess Proceeds, at a purchase price in cash in an amount equal to
100% of the principal amount thereof plus accrued and unpaid interest, if any,
thereon, to the date of purchase in accordance with the procedures set out in
this Indenture. To the extent that the aggregate amount of Notes (and any Other
Indebtedness subject to such Asset Sale Offer) tendered pursuant to such Asset
Sale Offers is less than the Excess Proceeds, the Company may, subject to the
other terms of this Indenture, use any remaining Excess Proceeds for any purpose
not prohibited by this Indenture. If the aggregate principal amount of Notes
surrendered by Holders thereof in connection with any Asset Sale Offer exceeds
the amount of Excess Proceeds, the Trustee shall select the Notes to be
purchased on a PRO RATA basis. Upon completion of the offer to purchase made
under this Indenture, the amount of Excess Proceeds that was the subject of such
offer to purchase shall be reset at zero.

          (b)  The Company shall mail (or cause the Trustee to mail) a notice of
a Asset Sale Offer by first-class mail, postage prepaid, to the record Holders
as shown on the register of Holders within 30 days following the Asset Sale
Offer Trigger Date, with a copy, if such notice is being mailed by the Company,
to the Trustee, containing all instructions and materials necessary to enable
such Holders to tender Notes pursuant to the Asset Sale Offer and shall state
the following terms:

          (1)  that the Asset Sale Offer is being made pursuant to this Section
               4.12, that all Notes tendered will be accepted for payment;
               PROVIDED, HOWEVER, that if the aggregate principal amount of
               Notes and other Indebtedness tendered in a Asset Sale Offer plus
               accrued interest at the expiration of such offer exceeds the
               Excess Proceeds, the Company shall select on a PRO RATA basis,
               the Notes and Other Indebtedness to be purchased (with such
               adjustments as may be deemed appropriate by the

<Page>

                                      -62-

               Company so that only Notes in denominations of $1,000, as
               applicable, or multiples thereof shall be purchased);

          (2)  the offer price (including the amount of accrued interest) and
               the Asset Sale Offer date of payment ("ASSET SALE OFFER PAYMENT
               DATE"), which shall be not less than 30 nor more than 60 days
               following the date notice of the applicable Asset Sale Offer is
               mailed;

          (3)  that any Note not tendered will continue to accrue interest;

          (4)  that, unless the Company defaults in making payment therefor, any
               Note accepted for payment pursuant to the Asset Sale Offer shall
               cease to accrue interest after the Asset Sale Offer Payment Date;

          (5)  that Holders electing to have a Note purchased pursuant to an
               Asset Sale Offer will be required to surrender such Note, with
               the form entitled "Option of Holder to Elect Purchase" on the
               reverse of the Note completed, to the Paying Agent at the address
               specified in the notice prior to the close of business on the
               third Business Day prior to the Asset Sale Offer Payment Date;

          (6)  that Holders will be entitled to withdraw their election if the
               Paying Agent receives, not later than the second Business Day
               prior to the Asset Sale Offer Payment Date, a telegram, telex,
               facsimile transmission or letter setting forth the name of such
               Holder, the principal amount of the Notes such Holder delivered
               for purchase and a statement that such Holder is withdrawing his
               election to have such Note purchased; and

          (7)  that Holders whose Notes are purchased only in part will be
               issued new Notes in a principal amount equal to the unpurchased
               portion of the Note surrendered; PROVIDED, HOWEVER, that each
               Note purchased and each new Note issued shall be in a principal
               amount of $1,000 or integral multiples thereof.

          (c)  On or before the Asset Sale Offer Payment Date, the Company shall
(1) accept for payment Notes or portions thereof (in integral multiples of
$1,000) validly tendered pursuant to the Asset Sale Offer, (2) deposit with the
Paying Agent an amount sufficient to pay the purchase price plus accrued and
unpaid interest, if any, of all Notes to be purchased and (3) deliver or cause
to be delivered to the Trustee the Notes so accepted together with an Officers'
Certificate stating the aggregate principal amount of Notes or portions of Notes
being purchased by the Company. Upon receipt by the Paying Agent of the monies
specified in clause (b) above and a copy of the Officers' Certificate specified
in clause (3) above, the Paying

<Page>

                                      -63-

Agent shall promptly mail to the Holders of Notes so accepted payment in an
amount equal to the purchase price plus accrued and unpaid interest, if any, out
of the funds deposited with the Paying Agent in accordance with the preceding
sentence. The Trustee shall promptly authenticate and mail (or cause to be
transferred by book entry) to such Holders new Notes equal in principal amount
to any unpurchased portion of the Notes surrendered, if any. Upon the payment of
the purchase price for the Notes accepted for purchase, the Trustee shall return
the Notes purchased to the Company for cancellation. Any monies remaining after
the purchase of Notes pursuant to a Asset Sale Offer shall be returned within
three business days by the Trustee to the Company except with respect to monies
owed as obligations to the Trustee pursuant to Article Seven. For purposes of
this Section 4.12, the Trustee shall act as the Paying Agent.

          (d)  To the extent the amount of Notes tendered pursuant to any Asset
Sale Offer is less than the amount of Net Cash Proceeds subject to such Asset
Sale Offer, the Company may use any remaining portion of such Net Cash Proceeds
not required to fund the repurchase of tendered Notes for any purpose not
prohibited by the Indenture and the amount of Excess Proceeds shall be reset to
zero.

          (e)  The Company will comply with the requirements of Rule 14e-1 under
the Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Notes pursuant to a Asset Sale Offer. To the extent that the
provisions of any securities laws or regulations conflict with the provisions of
this Section 4.12, the Company shall comply with the applicable securities laws
and regulations and shall not be deemed to have breached its obligations under
the provisions of this Section 4.12 by virtue thereof.

SECTION 4.13.  LIMITATION ON DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING
               RESTRICTED SUBSIDIARIES.

          From and after the Assumption Date, the Company will not, and will not
permit any of its Restricted Subsidiaries to, directly or indirectly, create or
otherwise cause or suffer to exist or become effective any restriction on the
ability of any Restricted Subsidiary to:

     (i)       (a)  pay dividends or make any other distributions to the Company
     or any of its Restricted Subsidiaries

               (1)  on its Capital Stock, or

               (2)  with respect to any other interest or participation in, or
          measured by, its profits, or

<Page>

                                      -64-

               (b)  pay any Indebtedness owed to the Company or any of its
     Restricted Subsidiaries;

     (ii)      make loans or advances to the Company or any of its Restricted
     Subsidiaries; or

     (iii)     transfer any of its properties or assets to the Company or any of
     its Restricted Subsidiaries;

except for such restrictions existing under or by reason of:

          (a)  existing agreements as in effect on the Issue Date, including any
     amendment, modification or supplement thereof PROVIDED that such amendment,
     modification or supplement is materially no more restrictive than such
     existing agreement as in effect on the Issue Date;

          (b)  Indebtedness permitted by this Indenture to be incurred
     containing restrictions on the ability of Restricted Subsidiaries to
     consummate transactions of the types described in clause (i), (ii) or (iii)
     above not materially more restrictive than those contained in this
     Indenture and the Security Documents;

          (c)  this Indenture and the Security Documents;

          (d)  applicable law;

          (e)  existing restrictions with respect to a Person acquired by the

     the properties or assets of any Person, other than the Person, or the
     property or assets of the Person, so acquired;

          (f)  customary non-assignment provisions in leases and other
     agreements entered into in the ordinary course of business;

          (g)  construction loans and Purchase Money Obligations (including

          (i)  a Permitted Refinancing; PROVIDED that the restrictions contained
     in the agreements governing such Permitted Refinancing are not materially
     more restrictive, taken as a whole, than those contained in the agreements
     governing the Indebtedness being refinanced;

          (j)  any restriction with respect to shares of Capital Stock of a
     Restricted Subsidiary imposed pursuant to an agreement entered into for the
     sale or disposition of such shares of Capital Stock or any restriction with

     effect on the Assumption Date and as amended, modified, extended, renewed,
     refunded, refinanced, restated or replaced from time to time; PROVIDED that
     the Credit Facility and related documentation as so amended, modified,
     extended, reviewed, refunded, refinanced, restated or replaced is not
     materially more restrictive, taken as a whole, as to the matters enumerated
     above than the Credit Facility and related documentation as in effect on
     the Assumption Date.

          For purposes of determining compliance with this Section 4.13, in the
event that a restriction meets the criteria of more than one of the categories
of permitted restrictions described in clauses (a) through (k) above, the
Company shall, in its sole discretion, classify such restriction in any matter
that complies with this Section 4.13 and such restriction will be treated as
existing pursuant to the clauses designated by the Company.

SECTION 4.14.  LIMITATION ON TRANSACTIONS WITH AFFILIATES.

          Prior to the Assumption Date, the Company will not enter into or
suffer to exist any Affiliate Transaction (as defined below) other than to the
extent necessary to consummate the Solutia Assumption and the transactions
contemplated thereby.

          From and after the Assumption Date, the Company will not, and will not
permit any of its Restricted Subsidiaries to, sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make any contract, agreement, understanding, loan,
advance or Guarantee with, or for the benefit of, any Affiliate (each of the
foregoing, an "AFFILIATE TRANSACTION"), unless (i) the terms of such Affiliate
Transaction are no less favorable to the Company or such Restricted Subsidiary,
as the case may be, than those that could be obtained in a comparable
arm's-length transaction with a Person that is not an Affiliate of the Company
and (ii) the Company delivers to the Trustee (a) with respect to any Affiliate
Transaction involving aggregate consideration in excess of $10 million, a
resolution of the Board of Directors set forth in an Officers' Certificate
certifying

<Page>

                                      -66-

that such Affiliate Transaction complies with clause (i) above and that such
Affiliate Transaction has been approved by a majority of the Disinterested
Members of the Board of Directors and (b) with respect to any Affiliate
Transaction involving aggregate consideration in excess of $25 million, an
opinion as to the fairness to the Company or such Restricted Subsidiary of such
Affiliate Transaction from a financial point of view issued by an investment
banking firm of national standing; PROVIDED that:

          (i)       transactions or payments pursuant to any employment
          arrangements or employee, officer or director benefit plans or
          arrangements entered into by the Company or any of its Restricted
          Subsidiaries in the ordinary course of business;

          (ii)      transactions between or among the Company and/or its
          Restricted Subsidiaries;

          (iii)     customary loans, advances, fees and compensation paid to,
          and indemnity provided on behalf of, officers, directors, employees or
          consultants of the Company or any of its Restricted Subsidiaries;

          (iv)      transactions pursuant to any contract or agreement in effect
          on the Issue Date, as the same may be amended, modified or replaced
          from time to time, so long as any such contract or agreement as so
          amended, modified or replaced is, taken as a whole, no less favorable
          to the Company and its Restricted Subsidiaries in any material respect
          than the contract or agreement as in effect on the Issue Date;

          (v)       any Restricted Payment of the type described in clause (1)
          or (2) of the first paragraph of Section 4.10; and

          (vi)      any transaction entered into on an arm's-length basis in the
          ordinary course of business between the Company or any of its
          Restricted Subsidiaries, on the one hand, and any Joint Venture, on
          the other hand; PROVIDED, that any such transaction (or series of
          related transactions) that involves $25 million or more in the
          aggregate shall be subject to prior approval by the Disinterested
          Members of the Board of Directors,

in each case, shall be deemed not to be Affiliate Transactions and therefore
(except as otherwise specified in such clauses) not subject to the requirements
of clauses (i) and (ii) of the initial paragraph above.

SECTION 4.15.  LIMITATION ON SALE AND LEASEBACK TRANSACTIONS.

          Prior to the Assumption Date, the Company will not enter into any Sale

          From and after the Assumption Date, the Company will not, and will not
permit any of its Restricted Subsidiaries to, enter into any Sale and Leaseback
Transaction; PROVIDED that the Company or any Restricted Subsidiary may enter
into a Sale and Leaseback Transaction if:

          (a)  the Company or such Restricted Subsidiary, as the case may be,
     could have:

          (i)       incurred Indebtedness in an amount equal to the Attributable
          Debt relating to such Sale and Leaseback Transaction pursuant to
          Section 4.09 and

          (ii)      incurred a Lien to secure such Indebtedness pursuant to
          Section 4.11 without securing the Notes; and

          (b)  the gross cash proceeds of such Sale and Leaseback Transaction

          Prior to the Assumption Date, the Company will not engage in any line

Indenture, the Escrow Agreement and the Solutia Assumption.

          From and after the Assumption Date, the Company will not, and will not
permit any of its Restricted Subsidiaries to, engage in any business other than
Permitted Businesses, except to such extent as would not be material to the
Company and its Subsidiaries taken as a whole.

SECTION 4.18.  REPORTS TO HOLDERS.

          Whether or not the Company and the Subsidiary Guarantors are then
subject to Section 13 (a) or 15(d) of the Exchange Act, from and after the
Assumption Date, the Company and the Subsidiary Guarantors will electronically
file with the SEC, so long as the Notes are outstanding, the annual reports,
quarterly reports and other periodic reports that the Company and the Subsidiary
Guarantors would be required to file with the SEC pursuant to Section 13(a) or
15 (d) if the Company and the Subsidiary Guarantors were so subject, and such
documents will be filed with the SEC on or prior to the respective dates (the
"REQUIRED FILING DATES") by which the Company and the Subsidiary Guarantors
would be required so to file

<Page>

                                      -68-

such documents if the Company and the Subsidiary Guarantors were so subject,
unless, in any case, such filings are not then permitted by the SEC.

          If such filings with the SEC are not then permitted by the SEC, or
such filings are not generally available on the Internet free of charge, from
and after the Assumption Date, the Company and the Subsidiary Guarantors will,
without charge to the Holders, within 15 days of each Required Filing Date,
transmit by mail to Holders, as their names and addresses appear in the note
register, and file with the Trustee copies of the annual reports, quarterly
reports and other periodic reports that the Company and the Subsidiary
Guarantors would be required to file with the SEC pursuant to Section 13(a) or
15(d) of the Exchange Act if the Company and the Subsidiary Guarantors were
subject to such Section 13(a) or 15(d) and, promptly upon written request,
supply copies of such documents to any prospective Holder or beneficial owner at
the Company's cost.

          In addition, from and after the Solutia Assumption, the Company and
the Subsidiary Guarantors will, for so long as any Notes remain outstanding,
furnish to the Holders of the Notes and to securities analysts and prospective
investors, upon their request, the information if any, required to be delivered
pursuant to Rule 144A(d)(4) under the Securities Act.

SECTION 4.19.  CREATION OF SUBSIDIARIES; GUARANTEES BY RESTRICTED SUBSIDIARIES.

          (a)  Prior to the Assumption Date, the Company will not create or
acquire any Subsidiaries.

          (b)  From and after the Assumption Date, the Company will not permit
any Restricted Subsidiary that is not a Subsidiary Guarantor, directly or
indirectly, to Guarantee or secure the payment of any other Indebtedness of the
Company or any of its Restricted Subsidiaries unless such Restricted Subsidiary
simultaneously executes and delivers a supplemental indenture to this Indenture
providing for a Subsidiary Guarantee of the payment of the Notes by such
Restricted Subsidiary; PROVIDED that this Section 4.19(b) shall not be
applicable to:

     (i)       any Guarantee of any Restricted Subsidiary that existed at the
     time such Person became a Restricted Subsidiary and was not incurred in
     connection with, or in contemplation of, such Person becoming a Restricted
     Subsidiary;

     (ii)      to the extent permitted under Section 4.09, Guarantees of
     Indebtedness of a Restricted Subsidiary that is a Foreign Subsidiary by a

<Page>

                                      -69-

     (iii)     any Guarantee arising under or in connection with performance
     bonds, indemnity bonds, surety bonds or letters of credit or bankers'
     acceptances.

          (c)  If the Guaranteed Indebtedness is subordinated in right of
payment to the Notes or any Subsidiary Guarantee, as applicable, pursuant to a
written agreement to that effect, the Guarantee of such guaranteed Indebtedness
must be subordinated in right of payment to the Subsidiary Guarantee to at least
the extent that the Guaranteed Indebtedness is subordinated to the Notes.

SECTION 4.20.  COVENANTS APPLICABLE IF NOTES RATED INVESTMENT GRADE.

          Notwithstanding anything in this Indenture, from and after the first
date when the Notes are rated Investment Grade, the Company's obligations to
comply with the provisions of the Indenture described under Sections 4.08, 4.09,
4.10, 4.13, 4.14, 4.15, 4.17 and Section 5.01(3) will terminate and cease to
have any further effect.

          In addition to the foregoing, from and after the first date when the
Notes are rated Investment Grade, the following shall apply:

          The Company will not, nor will it permit any Restricted Subsidiary to,
     enter into any Sale and Lease-Back Transaction (except a lease for a
     temporary period not exceeding three years) after the Issue Date covering
     any Principal Property, which was or is owned or leased by the Company or a
     Restricted Subsidiary and which has been or is to be sold or transferred
     more than 120 days after the acquisition or completion of construction and
     commencement of full operation thereof, unless (a) the Attributable Debt in
     respect thereto and all other Sale and Lease-Back Transactions entered into
     after the date of the Indenture (other than those the proceeds of which are
     applied to reduce Indebtedness under (b) below), plus the aggregate amount
     of then outstanding secured Indebtedness not otherwise permitted or
     excepted without equally and ratably securing the Notes, does not exceed
     15% of the Consolidated Net Tangible Assets of the Company and its
     Restricted Subsidiaries or (b) an amount equal to the fair value of the
     Principal Property leased is applied within 120 days to the voluntary
     retirement of the Note or other Indebtedness maturing more than one year
     thereafter.

SECTION 5.01.  CONSOLIDATION, MERGER AND SALE OF ASSETS.

          Except in connection with the Solutia Assumption and the related
release of the Escrow Assets or the redemption of the Notes, prior to the
Assumption Date the Company will not, in a single transaction or a series of
related transactions, consolidate or merge with or into (whether or not the
Company is the surviving entity) or transfer all or substantially all of its
properties or assets to another Person.

          Except in connection with the Solutia Assumption, from and after the
Assumption Date, the Company may not consolidate with or merge with or into, or
sell, assign, transfer, convey or otherwise dispose of all or substantially all
of its assets in one or more related transactions to, any Person, or permit any

     related incurrence of Indebtedness or issuance of Disqualified Stock, no
     Default or Event of Default shall have occurred and be continuing;

          (2)  either (i) the Company shall be the continuing Person, or (ii)
     the entity formed by such consolidation or into which the Company is
     merged, or the Person to which such properties and assets will have been
     conveyed, transferred or leased, assumes the Company's obligation as to the
     due and punctual payment of the principal of (and premium, if any, on) and
     interest, if any, on the Notes and the performance and observance of every
     covenant to be performed by the Company under this Indenture, the Notes and
     the Security Documents; any such entity will be organized under the laws of
     the United States, one of the States thereof or the District of Columbia;

          (3)  the Company or the entity or the Person formed by or surviving
     any such consolidation or merger (if other than the Company), or to which
     such sale, assignment, transfer, conveyance or other disposition shall have
     been made, except with respect to a consolidation or merger of the Company
     with or into a Person that has no outstanding Indebtedness, will, at the
     time of such transaction and after giving PRO FORMA effect thereto as if
     such transaction had occurred at the beginning of the applicable
     four-quarter period, have a Fixed Charge Coverage Ratio of at least 2 to 1;
     and

          (4)  the Company has delivered to the Trustee an Officers' Certificate

<Page>

                                      -71-

          The foregoing shall not prohibit the merger or consolidation of a
Wholly Owned Restricted Subsidiary with the Company; PROVIDED that, in
connection with any such merger or consolidation, no consideration, other than
Qualified Capital Stock in the Surviving Person or the Company, shall be issued
or distributed to the holders of Capital Stock of the Company.

          No Subsidiary Guarantor will be permitted to:

     (i)       consolidate with or merge with or into any Person; or

     (ii)      sell, convey, transfer or dispose of, all or substantially all
     its assets as an entirety or substantially as an entirety, in one
     transaction or a series of related transactions, to any Person; or

     (iii)     permit any Person to merge with or into the Subsidiary Guarantor
unless:

          (A)  the other Person is the Company or any Wholly Owned Restricted
     Subsidiary that is a Subsidiary Guarantor or becomes a Subsidiary Guarantor
     concurrently with the transaction; or

          (B)  (1)  either (x) the Subsidiary Guarantor is the continuing Person
     or (y) the resulting, surviving or transferee Person expressly assumes by
     supplemental indenture all of the obligations of the Subsidiary Guarantor
     under its Subsidiary Guarantee; and

               (2)  immediately after giving effect to the transaction, no
     Default has occurred and is continuing;

     or

          (C)  the transaction constitutes a sale or other disposition
     (including by way of consolidation or merger) of the Subsidiary Guarantor
     or the sale or disposition of all or substantially all the assets of the
     Subsidiary Guarantor (in each case other than to the Company or a
     Restricted Subsidiary) otherwise permitted by this Indenture.

          The sale, assignment, transfer, conveyance or other disposition by the
Company of all or substantially all its property or assets taken as a whole to
one or more of the Company's Subsidiaries shall not relieve the Company from its
obligations under this Indenture and the Notes. In addition, the Company will
not lease all or substantially all its assets in one or more related
transactions to another Person.

SECTION 5.02.  SUCCESSOR PERSON SUBSTITUTED.

          Upon any consolidation or merger, or any transfer of all or
substantially all of the assets of either the Company or any Restricted
Subsidiary in accordance with Section 5.01 above, the successor corporation
formed by such consolidation or into which the Company is merged or to which
such transfer is made shall succeed to, and be substituted for, and may exercise
every right and power the Company or such Restricted Subsidiary under this
Indenture with the same effect as if such successor corporation had been named
as the Company or such Restricted Subsidiary herein, and thereafter the
predecessor corporation shall be relieved of all obligations and covenants under
this Indenture and the Notes.

                                   ARTICLE SIX

                              DEFAULTS AND REMEDIES

SECTION 6.01.  EVENTS OF DEFAULT.

          Each of the following constitutes an "EVENT OF DEFAULT" with respect

          (5)  any default occurs under any mortgage, indenture or instrument
     under which there may be issued or by which there may be secured or
     evidenced any Indebtedness for money borrowed by the Company or any of its
     Significant Subsidiaries (or any Indebtedness for money borrowed Guaranteed
     by the Company or any of its Significant Subsidiaries if the Company or a
     Significant Subsidiary does not perform its payment obligations under such
     Guarantee within any grace period provided for in the documentation
     governing such Guarantee), whether such Indebtedness or Guarantee exists on
     the Issue Date or is thereafter created, which default (a) constitutes a
     Payment

<Page>

                                      -73-

     Default or (b) results in the acceleration of such Indebtedness prior
     to its Stated Maturity, and in each case, the principal amount of any such
     Indebtedness, together with the principal amount of any other such
     Indebtedness under which there has been a Payment Default or that has been
     so accelerated, aggregates $35 million or more;

          (6)  failure by the Company or any of its Significant Subsidiaries to
     pay a final judgment or final judgments aggregating in excess of $35
     million, which judgment or judgments are not paid, discharged or stayed,
     for a period of 60 days;

          (7)  (A) a court having jurisdiction over the Company or any of its
     applicable Significant Subsidiaries enters (x) a decree or order for relief
     in respect of the Company or any of its Significant Subsidiaries in an
     involuntary case or proceeding under any applicable federal or state
     bankruptcy, insolvency, reorganization or other similar law or (y) a decree
     or order adjudging the Company or any of its Significant Subsidiaries a
     bankrupt or insolvent, or approving as properly filed a petition seeking
     reorganization, arrangement, adjustment or composition of or in respect of
     the Company or any of its Significant Subsidiaries under any applicable
     federal or state law, or appointing a custodian, receiver, liquidator,
     assignee, trustee, sequestrator or other similar official of the Company or
     any of its Significant Subsidiaries or of any substantial part of its
     property, or ordering the winding up or liquidation of its affairs, and the

     Company or any Significant Subsidiary or (iii) effects any general
     assignment for the benefit of creditors; or

          (8)  any Subsidiary Guarantee or any Security Document (or any
     security interest created thereby) shall be held in any judicial proceeding
     to be unenforceable or invalid or shall cease for any reason to be in full
     force and effect or the Company or any Subsidiary Guarantor, or any Person
     acting on behalf of any Subsidiary Guarantor, shall deny or disaffirm its
     obligations under any Subsidiary Guarantee or any Security Document.

SECTION 6.02.  ACCELERATION OF MATURITY; RESCISSION.

          If an Event of Default (other than an Event of Default specified in
6.01(7) occurs with respect to the Company or any Subsidiary Guarantor) occurs
and is continuing under this Indenture, the Trustee or the Holders of at least
25% in aggregate principal amount of the

<Page>

                                      -74-

Notes then outstanding, by written notice to the Company (and to the Trustee if
such notice is given by the Holders), may, and the Trustee at the request of
such Holders shall, declare the principal of and premium, if any, and accrued
interest, if any, on the Notes to be immediately due and payable. Upon a
declaration of acceleration, such principal, premium, if any, and accrued
interest, if any, shall be immediately due and payable. If an Event of Default
specified in 6.01(7) occurs with respect to the Company or any Subsidiary
Guarantor, the principal of and premium, if any, and accrued interest, if any,
on the Notes then outstanding shall become and be immediately due and payable
without any declaration or other act on the part of the Trustee or any Holder.
If an Event of Default occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

          The Holders of at least a majority in principal amount of the
outstanding Notes, by written notice to the Company and to the Trustee, may
waive all past defaults and rescind and annul a declaration of acceleration and
its consequences if:

     (i)       all existing Events of Default, other than the nonpayment of the
     principal of and premium, if any, and interest, if any, on such Notes that
     have become due solely by such declaration of acceleration, have been cured
     or waived; and

     (ii)      the rescission would not conflict with any judgment or decree of
     a court of competent jurisdiction.

SECTION 6.03.  OTHER REMEDIES.

          If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy by proceeding at law or in equity to collect the
payment of principal of, or premium, if any, and interest on the Notes or to
enforce the performance of any provision of the Notes or this Indenture and may
take any necessary action requested of it as Trustee to settle, compromise,
adjust or otherwise conclude any proceedings to which it is a party.

          The Trustee may maintain a proceeding even if it does not possess any
of the Notes or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Noteholder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative. Any costs
associated with actions taken by the Trustee under this Section 6.03 shall be
reimbursed to the Trustee by the Company.

SECTION 6.04.  WAIVER OF PAST DEFAULTS AND EVENTS OF DEFAULT.

          Provided the Notes are not then due and payable by reason of a
declaration of acceleration, the Holders of a majority in principal amount of
Notes at the time outstanding may on behalf of the Holders of all the Notes
waive any past Default with respect to such Notes and its consequences by
providing written notice thereof to the Company and the Trustee, except a
Default (1) in the payment of interest on or the principal of any Note or (2) in
respect of a covenant or provision hereof which under this Indenture cannot be
modified or amended without the consent of the Holder of each outstanding Note
affected. In the case of any such waiver, the Company, the Trustee and the
Holders of the Notes will be restored to their former positions and rights under
this Indenture, respectively; PROVIDED that no such waiver shall extend to any
subsequent or other Default or impair any right consequent thereto.

SECTION 6.05.  CONTROL BY MAJORITY.

          The Holders of at least a majority in aggregate principal amount of
the outstanding Notes may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee. However, the Trustee may refuse to follow any
direction that conflicts with law or this Indenture, that may involve the
Trustee in personal liability, or that the Trustee determines in good faith may
be unduly prejudicial to the rights of Holders of the Notes not joining in the
giving of such direction and may take any other action it deems proper that is
not inconsistent with any such direction received from Holders of the Notes. A
Holder may not pursue any remedy with respect to this Indenture or the Notes
unless:

          (1)  the Holder gives the Trustee written notice of a continuing Event
     of Default;

          (2)  the Holders of at least 25% in aggregate principal amount of
     outstanding Notes make a written request to the Trustee to pursue the
     remedy;

          (3)  such Holder or Holders offer the Trustee indemnity satisfactory
     to the Trustee against any costs, liability or expense;

          (4)  the Trustee does not comply with the request within 60 days after
     receipt of the request and the offer of indemnity; and

          (5)  during such 60-day period, the Holders of at least a majority in
     aggregate principal amount of the outstanding Notes do not give the Trustee
     a direction that is inconsistent with the request.

<Page>

                                      -76-

          However, such limitations do not apply to the right of any Holder of a
Note to receive payment of the principal of or premium, if any, or interest, if
any, on such Note or to bring suit for the enforcement of any such payment, on
or after the due date expressed in the Notes, which right shall not be impaired
or affected without the consent of the Holder.

SECTION 6.06.  LIMITATION ON SUITS.

          A Holder may not pursue any remedy with respect to this Indenture or
the Notes unless:

          (1)  the Holder gives the Trustee written notice of a continuing Event
     of Default;

          (2)  the Holders of at least 25% in aggregate principal amount of
     outstanding Notes make a written request to the Trustee to pursue the
     remedy;

          (3)  such Holder or Holders offer the Trustee indemnity satisfactory
     to the Trustee against any costs, liability or expense;

          (4)  the Trustee does not comply with the request within 60 days after
     receipt of the request and the offer of indemnity; and

          (5)  during such 60-day period, the Holders of at least a majority in
     aggregate principal amount of the outstanding Notes do not give the Trustee
     a direction that is inconsistent with the request.

          A Noteholder may not use this Indenture to prejudice the rights of
another Noteholder or to obtain a preference or priority over another
Noteholder.

SECTION 6.07.  NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND
               STOCKHOLDERS.

          No director, officer, employee, incorporator, member of the Board of
Directors or holder of Capital Stock of the Company or any Subsidiary Guarantor,
as such, will have any liability for any obligations of the Company and the
Subsidiary Guarantors under the Notes, the Subsidiary Guarantees, this Indenture
or the Security Documents or for any claim based on, in respect of, or by reason
of, such obligations. Each Holder of Notes by accepting a Note waives and
releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes. This waiver may not be effective to
waive liabilities under the federal securities laws and it is the view of the
SEC that such a waiver is against public policy.

                                      -77-

SECTION 6.08.  RIGHTS OF HOLDERS TO RECEIVE PAYMENT.

          Notwithstanding any other provision of this Indenture, the right of
any Holder of a Note to receive payment of the principal of or premium, if any,
or interest, if any, on such Note or to bring suit for the enforcement of any
such payment, on or after the due date expressed in the Notes shall not be
impaired or affected without the consent of the Holder.

SECTION 6.09.  COLLECTION SUIT BY TRUSTEE.

          If an Event of Default in payment of principal, premium or interest
specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company or any Subsidiary Guarantor (or any other obligor on the Notes) for the
whole amount of unpaid principal and accrued interest remaining unpaid, together
with interest on overdue principal and, to the extent that payment of such
interest is lawful, interest on overdue installments of interest, in each case
at the rate set forth in the Notes, and such further amounts as shall be
sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

SECTION 6.10.  TRUSTEE MAY FILE PROOFS OF CLAIM.

          The Trustee may file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.07) and the Noteholders allowed in any
judicial proceedings relative to the Company or any Subsidiary Guarantor (or any
other obligor upon the Notes), its creditors or its property and shall be
entitled and empowered to collect and receive any monies or other property
payable or deliverable on any such claims and to distribute the same after
deduction of its charges and expenses to the extent that any such charges and
expenses are not paid out of the estate in any such proceedings and any
custodian in any such judicial proceeding is hereby authorized by each
Noteholder to make such payments to the Trustee, and in the event that the
Trustee shall consent to the making of such payments directly to the
Noteholders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.07.

          Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Noteholder any plan
or reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Noteholder thereof, or to authorize the Trustee to vote in
respect of the claim of any Noteholder in any such proceedings. All rights of
action and claims under this Indenture or the Notes may be prosecuted and
enforced by the Trustee without the possession of any of the Notes thereof in

<Page>

                                      -78-

any proceeding relating thereto, and any such proceeding instituted by the
Trustee shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, be for the ratable benefit of the Noteholders in respect of which
such judgment has been recovered.

SECTION 6.11.  PRIORITIES.

          If the Trustee collects any money pursuant to this Article Six, it
shall pay out the money in the following order:

          FIRST: to the Trustee for amounts due under Section 7.07;

          SECOND: to Noteholders for amounts due and unpaid on the Notes for
     principal, premium, if any, and interest (including Liquidated Damages, if
     any) as to each, ratably, without preference or priority of any kind,
     according to the amounts due and payable on the Notes; and

          THIRD: to the Company or, to the extent the Trustee collects any
     amount from any Subsidiary Guarantor, to such Subsidiary Guarantor.

          The Trustee may fix a record date and payment date for any payment to
Noteholders pursuant to this Section 6.11.

SECTION 6.12.  UNDERTAKING FOR COSTS.

          In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees and expenses, against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section 6.12 does not apply to a suit by the Trustee, a suit by a
Noteholder pursuant to Section 6.08 or a suit by Noteholders of more than 10% in
principal amount of the Notes then outstanding.

                                  ARTICLE SEVEN

                                     TRUSTEE

SECTION 7.01.  DUTIES OF TRUSTEE.

          (a)  If an Event of Default actually known to a Responsible Officer of
the Trustee has occurred and is continuing, the Trustee shall exercise such of
the rights and powers vested in it by this Indenture and use the same degree of
care and skill in their exercise as a prudent person would exercise or use under
the same circumstances in the conduct of his or her own affairs.

          The Trustee shall not be deemed to have notice of any Default or Event
of Default unless a Responsible Officer of the Trustee has actual knowledge
thereof or unless written notice of any event which is in fact such a default is
received by the Trustee at the Corporate Trust Office of the Trustee, and such
notice references the Notes and this Indenture.

          (b)  Except during the continuance of an Event of Default:

          (1)  The Trustee need perform only those duties that are specifically
     set forth in this Indenture and no others.

          (2)  In the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture but, in
     the case of any such certificates or opinions which by any provision hereof
     are specifically required to be furnished to the Trustee, the Trustee shall
     be under a duty to examine the same to determine whether or not they
     conform on their face to the requirements of this Indenture (but need not
     confirm or investigate the accuracy of mathematical calculations or other
     facts stated therein). Whenever in the administration of this Indenture the
     Trustee shall deem it desirable that a matter be proved or established
     prior to taking, suffering or omitting any action hereunder, the Trustee
     (unless other evidence be herein specifically prescribed) may, in the
     absence of bad faith on its part, conclusively rely upon an Officers'
     Certificate, subject to the requirement in the preceding sentence, if
     applicable.

          (c)  The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

          (1)  This paragraph does not limit the effect of paragraph (b) of this
     Section 7.01.

<Page>

                                      -80-

          (2)  The Trustee shall not be liable for any error of judgment made in
     good faith, unless it is proved that the Trustee was negligent in
     ascertaining the pertinent facts.

          (3)  The Trustee shall not be liable with respect to any action it
     takes or omits to take in good faith in accordance with a direction
     received by it pursuant to the terms hereof.

          (4)  No provision of this Indenture shall require the Trustee to
     expend or risk its own funds or otherwise incur any financial liability in
     the performance of any of its rights, powers or duties if it shall have
     reasonable grounds for believing that repayment of such funds or adequate
     indemnity satisfactory to it against such risk or liability is not
     reasonably assured to it.

          (d)  Whether or not therein expressly so provided, paragraphs (a),
(b), (c) and (e) of this Section 7.01 shall govern every provision of this
Indenture that in any way relates to the Trustee.

          (e)  The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the Holders pursuant to this Indenture, unless such Holders shall have
offered to the Trustee security or indemnity satisfactory to the Trustee against
the costs, expenses and liabilities which might be incurred by it in compliance
with such request or direction.

          (f)  The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company or
any Subsidiary Guarantor. Money held in trust by the Trustee need not be
segregated from other funds except to the extent required by the law.

SECTION 7.02.  RIGHTS OF TRUSTEE.

          Subject to Section 7.01:

          (1)  The Trustee may conclusively rely on any document (whether in its
     original or facsimile form) reasonably believed by it to be genuine and to
     have been signed or presented by the proper person. The Trustee need not
     investigate any fact or matter stated in the document.

          (2)  Before the Trustee acts or refrains from acting, it may require
     an Officers' Certificate or an Opinion of Counsel, or both, which shall
     conform to the provisions of Section 12.05. The Trustee shall be protected
     and shall not be liable for any action it takes or omits to take in good
     faith in reliance on such certificate or opinion.

<Page>

                                      -81-

          (3)  The Trustee may act through its attorneys and agents and shall
     not be responsible for the misconduct or negligence of any agent appointed
     by it with due care.

          (4)  The Trustee shall not be liable for any action it takes or omits
     to take in good faith which it reasonably believes to be authorized or
     within its rights or powers; PROVIDED that the Trustee's conduct does not
     constitute gross negligence or bad faith.

          (5)  The Trustee may consult with counsel of its selection, and the
     advice or opinion of such counsel as to matters of law shall be full and
     complete authorization and protection from liability in respect of any
     action taken, omitted or suffered by it hereunder in good faith and in
     accordance with the advice or opinion of such counsel.

          (6)  The rights, privileges, protections, immunities and benefits
     given to the Trustee, including, without limitation, its right to be
     indemnified, are extended to, and shall be enforceable by, the Trustee in
     each of its capacities hereunder, and each agent, custodian and other
     person employed to act hereunder.

SECTION 7.03.  INDIVIDUAL RIGHTS OF TRUSTEE.

          The Trustee in its individual or any other capacity may become the
owner or pledgee of Notes and may make loans to, accept deposits from, perform
services for or otherwise deal with the either of the Company or any Subsidiary
Guarantor, or any Affiliates thereof, with the same rights it would have if it
were not Trustee. Any Agent may do the same with like rights. The Trustee,
however, shall be subject to Sections 7.10 and 7.11.

SECTION 7.04.  TRUSTEE'S DISCLAIMER.

          The Trustee shall not be responsible for and makes no representation
as to the validity or adequacy of this Indenture or the Notes or any Guarantee,
it shall not be accountable for the Company's or any Subsidiary Guarantor's use
of the proceeds from the sale of Notes or any money paid to the Company or any
Subsidiary Guarantor pursuant to the terms of this Indenture and it shall not be
responsible for any statement in the Notes, Guarantee or this Indenture other
than its certificate of authentication.

SECTION 7.05.  NOTICE OF DEFAULTS.

          If a Default occurs and is continuing and if it is known to the
Trustee, the Trustee shall give to each Noteholder a notice of the Default
within 90 days after it occurs in the manner and to the extent provided in the
TIA and otherwise as provided in this Indenture. Except in the case of a Default
in payment of the principal of or interest on any Note (including payments
pursuant to a redemption or repurchase of the Notes pursuant to the provisions

<Page>

                                      -82-

of this Indenture), the Trustee may withhold the notice if and so long as a
committee of its Responsible Officers in good faith determines that withholding
the notice is in the interests of Noteholders.

SECTION 7.06.  REPORTS BY TRUSTEE TO HOLDERS.

          If required by TIA Section 313(a), within 60 days after May 15 of any
year, commencing 2002 the Trustee shall mail to each Noteholder a brief report
dated as of such date that complies with TIA Section 313(a). The Trustee also
shall comply with TIA Section 313(b)(2). The Trustee shall also transmit by mail
all reports as required by TIA Section 313(c) and TIA Section 313(d).

          Reports pursuant to this Section 7.06 shall be transmitted by mail:

          (1)  to all Holders of Notes, as the names and addresses of such
     Holders appear on the Registrar's books; and

          (2)  to such Holders of Notes as have, within the two years preceding
     such transmission, filed their names and addresses with the Trustee for
     that purpose.

          A copy of each report at the time of its mailing to Noteholders shall
be filed with the Commission and each stock exchange on which the Notes are
listed. The Company shall promptly notify the Trustee when the Notes are listed
on any stock exchange or delisted therefrom.

SECTION 7.07.  COMPENSATION AND INDEMNITY.

          The Company and the Subsidiary Guarantors shall pay to the Trustee and
Agents from time to time reasonable compensation for their services hereunder
(which compensation shall not be limited by any provision of law in regard to
the compensation of a trustee of an express trust). The Company and the
Subsidiary Guarantors shall reimburse the Trustee and Agents upon request for
all reasonable disbursements, expenses and advances incurred or made by them in
connection with the Trustee's duties under this Indenture, including the
reasonable compensation, disbursements and expenses of the Trustee's agents and
external counsel, except any expense disbursement or advance as may be
attributable to its negligence or bad faith.

          The Company and the Subsidiary Guarantors, jointly and severally,
shall fully indemnify each of the Trustee and any predecessor Trustee for, and
hold each of them harmless against, any and all loss, damage, claim, liability
or expense, including without limitation taxes (other than taxes based on the
income of the Trustee or such Agent) and reasonable attorneys' fees and expenses
incurred by each of them in connection with the acceptance or performance of its
duties under this Indenture including the reasonable costs and expenses of
defending

<Page>

                                      -83-

itself against any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder (including, without
limitation, settlement costs). The Trustee or Agent shall notify the Company and
the Subsidiary Guarantors in writing promptly of any claim of which a
Responsible Officer of the Trustee has actual knowledge asserted against the
Trustee or Agent for which it may seek indemnity; PROVIDED that the failure by
the Trustee or Agent to so notify the Company and the Subsidiary Guarantors
shall not relieve the Company and Subsidiary Guarantors of their obligations
hereunder except to the extent the Company and the Subsidiary Guarantors are
actually prejudiced thereby. In the event that a conflict of interest exists,
the Trustee may have separate counsel and the Company shall pay the reasonable
fees and expenses of such counsel.

          Notwithstanding the foregoing, the Company and the Subsidiary
Guarantors need not reimburse the Trustee for any expense or indemnify it
against any loss or liability to have been incurred by the Trustee through its
own negligence or bad faith.

          To secure the payment obligations of the Company and the Subsidiary
Guarantors in this Section 7.07, the Trustee shall have a lien prior to the
Notes on all money or property held or collected by the Trustee except for
Escrow Assets and such money or property held in trust to pay principal of and
interest on particular Notes.

          The obligations of the Company and the Subsidiary Guarantors under
this Section 7.07 to compensate and indemnify the Trustee, Agents and each
predecessor Trustee and to pay or reimburse the Trustee, Agents and each
predecessor Trustee for expenses, disbursements and advances shall be joint and
several liabilities of the Company and each of the Subsidiary Guarantors and
shall survive the resignation or removal of the Trustee and the satisfaction,
discharge or other termination of this Indenture, including any termination or
rejection hereof under any Bankruptcy Law.

          When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(6) or (7) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

          For purposes of this Section 7.07, the term "Trustee" shall include
any trustee appointed pursuant to this Article Seven.

SECTION 7.08.  REPLACEMENT OF TRUSTEE.

          The Trustee may resign by so notifying the Company and the Subsidiary
Guarantors in writing. The Holders of a majority in principal amount of the
outstanding Notes may remove the Trustee by notifying the Company and the
removed Trustee in writing and may appoint a successor Trustee with the
Company's written consent, which consent shall not be unreasonably withheld. The
Company may remove the Trustee at its election if:

<Page>

                                      -84-

          (1)  the Trustee fails to comply with Section 7.10;

          (2)  the Trustee is adjudged a bankrupt or an insolvent;

          (3)  a receiver or other public officer takes charge of the Trustee or
     its property; or

          (4)  the Trustee otherwise becomes incapable of acting.

          If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee.

          If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holders of a majority in principal amount of the outstanding Notes may petition
at the expense of the Company any court of competent jurisdiction for the
appointment of a successor Trustee.

          If the Trustee fails to comply with Section 7.10, any Noteholder may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately following
such delivery, the retiring Trustee shall, subject to its rights under Section
7.07, transfer all property held by it as Trustee to the successor Trustee, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. A successor Trustee shall mail notice of its succession to
each Noteholder. Notwithstanding replacement of the Trustee pursuant to this
Section 7.08, the Company's obligations under Section 7.07 shall continue for
the benefit of the retiring Trustee.

SECTION 7.09.  SUCCESSOR TRUSTEE BY CONSOLIDATION, MERGER, ETC.

          If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all of its corporate trust assets to, another
corporation, subject to Section 7.10, the successor corporation without any
further act shall be the successor Trustee; PROVIDED such entity shall be
otherwise qualified and eligible under this Article Seven.

SECTION 7.10.  ELIGIBILITY; DISQUALIFICATION.

          This Indenture shall always have a Trustee who satisfies the
requirements of TIA Section 310(a)(1) and (2) in every respect. The Trustee
(together with its corporate parent) shall have a combined capital and surplus
of at least $100 million as set forth in the most recent

<Page>

                                      -85-

applicable published annual report of condition. The Trustee shall comply with
TIA Section 310(b), including the provision in Section 310(b)(1).

SECTION 7.11.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

          The Trustee shall comply with TIA Section 311(a), excluding any
creditor relationship listed in TIA Section 311 (b). A Trustee who has resigned
or been removed shall be subject to TIA Section 311(a) to the extent indicated
therein.

SECTION 7.12.  PAYING AGENTS.

          The Company shall cause each Paying Agent other than the Trustee to
execute and deliver to it and the Trustee an instrument in which such agent
shall agree with the Trustee, subject to the provisions of this Section 7.12:

          (A)  that it will hold all sums held by it as agent for the payment of
     principal of, or premium, if any, or interest on, the Notes (whether such
     sums have been paid to it by the Company or by any obligor on the Notes) in
     trust for the benefit of Holders of the Notes or the Trustee;

          (B)  that it will at any time during the continuance of any Event of
     Default, upon written request from the Trustee, deliver to the Trustee all
     sums so held in trust by it together with a full accounting thereof; and

          (C)  that it will give the Trustee written notice within three (3)
     Business Days of any failure of the Company (or by any obligor on the
     Notes) in the payment of any installment of the principal of, premium, if
     any, or interest on, the Notes when the same shall be due and payable.

     conditions;

         (iv)  to secure the Notes under this Indenture, to add Subsidiary

     Guarantee when such release, termination or discharge is permitted
     elsewhere in this Indenture;

          (v)  to add to the covenants of the Company for the benefit of the
     Holders of the Notes or to surrender any right or power conferred upon the

        (vii)  to make any other change that does not adversely affect the

Solutia will assume the obligations of SOI Funding hereunder, and the Subsidiary
Guarantors shall each execute the notation of guarantee in the form of Exhibit F
and deliver same to the Trustee. In addition (without notice to or consent of
any Holder), the Trustee and the other parties thereto shall enter into the
Junior Security Agreement and the Junior Intercreditor Agreement, substantially
in the forms attached hereto as EXHIBIT G and EXHIBIT H, respectively.

SECTION 8.02.  WITH CONSENT OF NOTEHOLDERS.

          (a)  The Company and the Trustee, with the consent of the Holders of
not less than a majority in aggregate principal amount of the Notes, to execute
supplemental indentures adding any provisions to or changing in any manner or
eliminating any provision of this Indenture or any Security Document or
modifying the rights of such Holders (it being understood that the provisions of
the Security Documents which may by their terms be amended

<Page>

                                      -87-

or waived without the consent of the Noteholders do not require the consent of
the Noteholders contemplated hereby).

          (b)  However, no modification or amendment may, without the consent of
each Holder affected thereby,

          (1)  change the Stated Maturity of the principal of, or any
     installment of interest on, any Note or alter the provisions with respect
     to redemption,

          (2)  reduce the principal amount of or premium, if any, or interest,
     if any, on any Note,

          (3)  reduce any amount payable upon the occurrence of an Event of

          (4)  after the obligation has arisen to make a Change of Control Offer
     or an Asset Sale Offer, amend, change or modify in any material respect the
     obligation of the Company to make and complete such Change of Control Offer
     or make and complete such Asset Sale Offer,

          (5)  change the place or currency of payment of principal of or
     premium, if any, or interest, if any, on any Note,

          (6)  impair the right to institute suit for the enforcement of any
     payment on or after the Stated Maturity (or, in the case of a redemption,
     on or after the Redemption Date) of any Note,

          (7)  reduce the above-stated percentage of outstanding Notes the
     consent of whose Holders is necessary to modify or amend this Indenture,

          (8)  waive a default in the payment of principal of or premium, if
     any, or interest, if any, on the Notes (except as set forth under Section
     6.01),

          (9)  reduce the percentage or aggregate principal amount of
     outstanding Notes the consent of whose Holders is necessary for waiver of
     compliance with certain provisions of this Indenture or for waiver of
     certain defaults,

          (10) modify or change any provision of this Indenture affecting the
     ranking of the Notes or the Subsidiary Guarantees in a manner adverse to
     the Holders of the Notes, or

          (11) release any Subsidiary Guarantor from any of its obligations
     under its Subsidiary Guarantee or this Indenture other than in accordance
     with the other provisions of this Indenture, or amend or modify any
     provision relating to such release.

<Page>

                                      -88-

          (c)  It shall not be necessary for the consent of the Holders under
this Section 8.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

          (d)  After an amendment, supplement or waiver under Section 8.01 or
this Section 8.02 becomes effective, the Company shall mail to the Holders a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amendment, supplement or
waiver.

          (e)  Upon the written request of the Company accompanied by a board
resolution authorizing the execution of any such supplemental indenture, and
upon the receipt by the Trustee of evidence reasonably satisfactory to the
Trustee of the consent of the Noteholders as aforesaid and upon receipt by the
Trustee of the documents described in Section 8.06, the Trustee shall join with
the Company in the execution of such supplemental indenture unless such
supplemental indenture affects the Trustee's own rights, duties or immunities
under this Indenture, in which case the Trustee may, but shall not be obligated
to, enter into such supplemental indenture.

SECTION 8.03.  COMPLIANCE WITH TRUST INDENTURE ACT.

          Every amendment or supplement to this Indenture or the Notes shall
comply with the TIA as then in effect.

SECTION 8.04.  REVOCATION AND EFFECT OF CONSENTS.

          (a)  After an amendment, supplement, waiver or other action becomes
effective, a consent to it by a Holder of a Note is a continuing consent
conclusive and binding upon such Holder and every subsequent Holder of the same
Note or portion thereof, and of any Note issued upon the transfer thereof or in
exchange therefor or in place thereof, even if notation of the consent is not
made on any such Note.

          (b)  The Company may, but shall not be obligated to, fix a record date
for the purpose of determining the Noteholders entitled to consent to any
amendment, supplement, or waiver. If a record date is fixed, then,
notwithstanding the preceding paragraph, those Persons who were Noteholders at
such record date (or their duly designated proxies), and only such Persons,
shall be entitled to consent to such amendment, supplement, or waiver or to
revoke any consent previously given, whether or not such Persons continue to be
Noteholders after such record date. No such consent shall be valid or effective
for more than 90 days after such record date unless the consent of the requisite
number of Noteholders has been obtained.

<Page>

                                      -89-

          (c)  After an amendment, supplement, waiver or other action becomes
effective, it shall bind every Noteholder, unless it makes a change described in
any of clauses (1) through (9) of Section 8.02. In that case the amendment,
supplement, waiver or other action shall bind each Noteholder who has consented
to it and every subsequent Noteholder or portion of a Note that evidences the
same debt as the consenting Holder's Note.

SECTION 8.05.  NOTATION ON OR EXCHANGE OF NOTES.

          If an amendment, supplement, or waiver changes the terms of a Note,
the Trustee (in accordance with the specific written direction of the Company)
shall request the Holder of the Note (in accordance with the specific written
direction of the Company) to deliver it to the Trustee. In such case, the
Trustee shall place an appropriate notation on the Note about the changed terms
and return it to the Noteholder. Alternatively, if the Company or the Trustee so
determines, the Company in exchange for the Note shall issue, the Subsidiary
Guarantors shall endorse, and the Trustee shall authenticate a new Note that
reflects the changed terms. Failure to make the appropriate notation or issue a
new Note shall not affect the validity and effect of such amendment, supplement
or waiver.

SECTION 8.06.  TRUSTEE TO SIGN AMENDMENTS, ETC.

          The Trustee shall sign any amendment, supplement or waiver authorized
pursuant to this Article Eight if the amendment, supplement or waiver does not
affect the rights, duties, liabilities or immunities of the Trustee. If it does
affect the rights, duties, liabilities or immunities of the Trustee, the Trustee
may, but need not, sign such amendment, supplement or waiver. In signing or
refusing to sign such amendment, supplement or waiver the Trustee shall be
entitled to receive and, subject to Section 7.01, shall be fully protected in
relying upon an Officers' Certificate and an Opinion of Counsel stating, in
addition to the matters required by Section 12.04, that such amendment,
supplement or waiver is authorized or permitted by this Indenture and is a
legal, valid and binding obligation of the Company and the Subsidiary
Guarantors, enforceable against the Company and the Subsidiary Guarantors in
accordance with its terms (subject to customary exceptions).

                       DISCHARGE OF INDENTURE; DEFEASANCE

SECTION 9.01.  DISCHARGE OF INDENTURE.

          Upon the request of the Company, this Indenture will cease to be of
further effect and the Trustee, at the expense of the Company, will execute
proper instruments acknowledging

<Page>

                                      -90-

satisfaction and discharge of the Notes and this Indenture and the Guarantees
when:

     (1)  either:

          (a)  all the Notes theretofore authenticated and delivered (other than
               destroyed, lost or stolen Notes that have been replaced or paid
               and Notes that have been subject to defeasance pursuant to
               Section 9.02 or 9.03) have been delivered to the Trustee for
               cancellation; or

          (b)  all Notes not theretofore delivered to the Trustee for
               cancellation:

          (i)       have become due and payable by the mailing of a notice of
                    redemption or otherwise;

          (ii)      will become due and payable within one year; or

          (iii)     are to be called for redemption within 12 months under
                    arrangements reasonably satisfactory to the Trustee for
                    the giving of notice of redemption by the Trustee in the
                    name, and at the reasonable expense, of the Company;

               and the Company has irrevocably deposited or caused to be
               deposited with the Trustee funds in trust for the purpose in an
               amount sufficient to pay and discharge the entire Indebtedness on
               the Notes not theretofore delivered to the Trustee for
               cancellation, for principal (and premium, if any) and interest on
               the Notes to the date of such deposit (in case of Notes that have
               become due and payable) or to the Stated Maturity or redemption
               date, as the case may be;

     (2)  the Company has paid or caused to be paid all sums payable under this
          Indenture by the Company; and

     (3)  the Company has delivered to the Trustee an Officers' Certificate and
          an Opinion of Counsel, each stating that all conditions precedent
          provided in this Indenture relating to the satisfaction and discharge
          of the Notes and this Indenture and the Guarantees of the Notes have
          been complied with.

          After such delivery, the Trustee upon request of the Company shall
acknowledge in writing the discharge of the Company's and the Subsidiary
Guarantors' obligations under the Notes, the Guarantees and this Indenture
except for those surviving obligations specified below.

<Page>

                                      -91-

          Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company in Sections 7.07, 9.05 and 9.06 shall survive such
satisfaction and discharge.

SECTION 9.02.  LEGAL DEFEASANCE.

          The Company may, at its option and at any time, elect to have its
obligations and the obligations of the Subsidiary Guarantors discharged with
respect to the outstanding Notes on a date the conditions set forth in Section
9.04 are satisfied (hereinafter, "LEGAL DEFEASANCE"). For this purpose, such
Legal Defeasance means that the Company will be deemed to have paid and
discharged the entire indebtedness represented by the outstanding Notes and to
have satisfied all its other obligations under such Notes and this Indenture
insofar as such Notes are concerned (and the Trustee, at the expense of the
Company, shall, subject to Section 9.06, execute instruments in form and
substance reasonably satisfactory to the Trustee and Company acknowledging the
same), except for the following which shall survive until otherwise terminated
or discharged hereunder: (A) the rights of Holders of outstanding Notes to
receive solely from the trust funds described in Section 9.04 and as more fully
set forth in such Section, payments in respect of the principal of, premium, if
any, and interest on such Notes when such payments are due, (B) the Company's
obligations with respect to such Notes under Sections 2.03, 2.04, 2.05, 2.06,
2,07, 2.08, 2.11, 4.02, 4.03 and 4.05, (C) the rights, powers, trusts, duties,
and immunities of the Trustee hereunder (including claims of, or payments to,
the Trustee under or pursuant to Section 7.07) and the Company's obligations in
connection therewith and (D) this Article Nine.

          Concurrently with any Legal Defeasance, the Company may, at its
further option, cause to be terminated, as of the date on which such Legal
Defeasance occurs, all of the obligations under any or all of the Guarantees, if
any, then existing and obtain the release of the Guarantee(s) of any or all
Subsidiary Guarantors. In order to exercise such option regarding a Guarantee,
the Company shall provide the Trustee with written notice of its desire to
terminate such Guarantee prior to the delivery of the Opinion of Counsel
referred to in clause (f) of Section 9.04.

          Subject to compliance with this Article Nine, the Company may exercise
its option under this Section 9.02 with respect to the Notes notwithstanding the
prior exercise of its option under Section 9.03 below with respect to the Notes.

SECTION 9.03.  COVENANT DEFEASANCE.

          The Company may, at its option and at any time, elect to have its
obligations and the obligations of the Subsidiary Guarantors under Sections
10.01, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.17, 4.18, 4.19, 4.20 (except
for obligations mandated by the TIA) and clauses (1) and (3) of Section 5.01
released with respect to the outstanding Notes on a date the

<Page>

                                      -92-

conditions set forth in Section 9.04 are satisfied (hereinafter, "COVENANT
DEFEASANCE"). For this purpose, Covenant Defeasance means that, with respect to
the outstanding Notes, the Company may fail to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event of Default under Section 6.01,
but, except as specified above, the remainder of this Indenture and such Notes
shall be unaffected thereby. In addition, upon the Company's exercise of the
option in this Section 9.03, subject to the satisfaction of the conditions set
forth in Section 9.04, Sections 6.01(5), (6) and (8) shall not constitute Events
of Default.

          Concurrently with any Covenant Defeasance, the Company may, at its
further option, cause to be terminated, as of the date on which such Covenant
Defeasance occurs, all of the obligations under any or all of the Guarantees, if
any, then existing and obtain the release of the Guarantee(s) of any or all
Subsidiary Guarantors. In order to exercise such option regarding a Guarantee,
the Company shall provide the Trustee with written notice of its desire to
terminate such Guarantee prior to the delivery of the Opinion of Counsel
referred to in clause (g) of Section 9.04.

          Notwithstanding any discharge or release of any obligations under this
Indenture pursuant to Section 9.02 or this Section 9.03, the Company's
obligations in Sections 2.04, 2.06, 2.07, 2.08, 7.07, 9.05, 9.06 and 9.08 shall
survive until such time as the Notes have been paid in full. Thereafter, the
Company's obligations in Sections 7.07, 9.05 and 9.08 shall survive.

SECTION 9.04.  CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

          The following shall be the conditions to application of Section 9.02
or Section 9.03 to the outstanding Notes:

     (a)  (1) the Company has irrevocably deposited or caused to be deposited in
          trust for the benefit of the Noteholders with the Trustee or a Paying
          Agent or a trustee satisfactory to the Trustee and the Company, under
          the terms of an irrevocable trust agreement in form and substance
          satisfactory to the Trustee and any such Paying Agent, (x) money in an
          amount sufficient, or (y) U.S. Government Obligations that shall be
          payable as to principal and interest in such amounts and at such times
          as are sufficient, in the opinion of a nationally recognized firm of
          independent public accountants or Independent Financial Advisors
          expressed in a written certification thereof delivered to the Trustee
          (without consideration of any reinvestment of such interest), or (z) a
          combination thereof in an amount, sufficient to pay the principal of
          (and premium, if any, on) and interest,

<Page>

                                      -93-

          if any, to Stated Maturity (or redemption) on such Notes, on the
          scheduled due dates therefor, (2) the trustee of the irrevocable trust
          has been irrevocably instructed to pay such money or the proceeds of
          such U.S. Government Obligations to the Trustee and (3) the Trustee or
          Paying Agent shall have been irrevocably instructed in writing to
          apply the deposited money and the proceeds from U.S. Government
          Obligations in accordance with the terms of this Indenture and the
          terms of the Notes to the payment of principal of and interest on the
          Notes;

     (b)  the deposit described in clause (a) above will not result in a breach
          or violation of, or constitute a Default under, any other agreement or
          instrument to which either the Company is a party or by which it is
          bound;

     (c)  no Default has occurred and is continuing (1) as of the date of such
          deposit (other than a Default resulting from the borrowing of funds to
          be applied to such deposit and the grant of any Lien securing such
          borrowing) or (2) insofar as clause (7) or (8) of Section 6.01 is
          concerned at any time during the period ending on the 91st day after
          the date of such deposit or, if longer, ending on the day following
          the expiration of the longest preference period applicable to the
          Company in respect of such deposit (it being understood that the
          condition in this clause (c) is a condition subsequent and will not be
          deemed satisfied until the expiration of such period);

     (d)  the Company has paid or caused to be paid all sums currently due and
          payable by the Company under this Indenture and under the Notes;

     (e)  the Company has delivered to the Trustee an Officers' Certificate and
          an Opinion of Counsel, each stating that all conditions precedent
          provided for in this Indenture relating to the termination by the
          Company of its obligations have been complied with;

     (f)  in the case of an election under Section 9.02 or 9.03, the Company has
          delivered to the Trustee an Opinion of Counsel to the effect that the
          Holders of such Notes will not recognize income, gain or loss for
          United States federal income tax purposes as a result of such legal
          defeasance or covenant defeasance and will be subject to United States
          federal income tax on the same amounts, in the same manner and at the
          same times as would have been the case if such defeasance or covenant
          defeasance had not occurred, and such opinion, in the case of
          defeasance under Section 9.02, must refer to and be based upon a
          ruling of the Internal Revenue Service or a change in applicable
          United States federal income tax law occurring after the date of the
          Indenture. The defeasance would

<Page>

                                      -94-

          in each case be effective when 91 days have passed since the date of
          the deposit in trust.

SECTION 9.05.  DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN
               TRUST; OTHER MISCELLANEOUS PROVISIONS.

          All money and U.S. Government Obligations (including the proceeds
thereof) deposited with the Trustee pursuant to Section 9.04 in respect of the
outstanding Notes shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Notes and this Indenture, to the payment,
either directly or through any Paying Agent, to the Holders of such Notes, of
all sums due and to become due thereon in respect of principal, premium, if any,
and accrued interest, but such money need not be segregated from other funds
except to the extent required by law.

          The Company and the Subsidiary Guarantors shall (on a joint and
several basis) pay and indemnify the Trustee against any tax, fee or other
charge imposed on or assessed against the U.S. Government Obligations deposited
pursuant to Section 9.04 or the principal, premium, if any, and interest
received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of the outstanding Notes.

          Anything in this Article Nine to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon a request of
the Company any money or U.S. Government Obligations held by it as provided in
Section 9.04 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance.

SECTION 9.06.  REINSTATEMENT.

          If the Trustee or Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with Section 9.01, 9.02 or 9.03 by reason
of any legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company's and each Subsidiary Guarantor's obligations under
this Indenture, the Notes and the Guarantees shall be revived and reinstated as
though no deposit had occurred pursuant to this Article Nine until such time as
the Trustee or Paying Agent is permitted to apply all such money or U.S.
Government Obligations in accordance with Section 9.01; PROVIDED that if the
Company or the Subsidiary Guarantors have made any payment of principal of,
premium, if any, or accrued interest on any Notes because of the reinstatement
of their obligations, the Company or the Subsidiary Guarantors, as the case may
be, shall be subrogated to the rights of the Holders of such Notes to receive
such payment from the money or U.S. Government Obligations held by the Trustee
or Paying Agent.

                                      -95-

SECTION 9.07.  MONEYS HELD BY PAYING AGENT.

          In connection with the satisfaction and discharge of this Indenture,
all moneys then held by any Paying Agent under the provisions of this Indenture
shall, upon written demand of the Company, be paid to the Trustee, or if
sufficient moneys have been deposited pursuant to Section 9.04, to the Company
upon a request of the Company (or, if such moneys had been deposited by the
Subsidiary Guarantors, to such Subsidiary Guarantors), and thereupon such Paying
Agent shall be released from all further liability with respect to such moneys.

SECTION 9.08.  MONEYS HELD BY TRUSTEE.

          Any moneys deposited with the Trustee or any Paying Agent or then held
by the Company or the Subsidiary Guarantors in trust for the payment of the
principal of, or premium, if any, or interest on any Note that are not applied
but remain unclaimed by the Holder of such Note for two years after the date
upon which the principal of, or premium, if any, or interest on such Note shall
have respectively become due and payable shall be repaid to the Company (or, if
appropriate, the Subsidiary Guarantors) upon a request of the Company, or if
such moneys are then held by the Company or the Subsidiary Guarantors in trust,
such moneys shall be released from such trust; and the Holder of such Note
entitled to receive such payment shall thereafter, as an unsecured general
creditor, look only to the Company and the Subsidiary Guarantors for the payment
thereof, and all liability of the Trustee or such Paying Agent with respect to
such trust money shall thereupon cease; PROVIDED that the Trustee or any such
Paying Agent, before being required to make any such repayment, may, at the
expense of the Company and the Subsidiary Guarantors, either mail to each
Noteholder affected, at the address shown in the register of the Notes
maintained by the Registrar pursuant to Section 2.04, or cause to be published
once a week for two successive weeks, in a newspaper published in the English
language, customarily published each Business Day and of general circulation in
the City of New York, New York, a notice that such money remains unclaimed and
that, after a date specified therein, which shall not be less than 30 days from
the date of such mailing or publication, any unclaimed balance of such moneys
then remaining will be repaid to the Company. After payment to the Company or
the Subsidiary Guarantors or the release of any money held in trust by the
Company or any Subsidiary Guarantors, as the case may be, Noteholders entitled
to the money must look only to the Company and the Subsidiary Guarantors for
payment as general creditors unless applicable abandoned property law designates
another Person.

                             GUARANTEE OF SECURITIES

SECTION 10.01. GUARANTEE.

          From and after the Assumption Date and subject to the provisions of
this Article Ten, the Subsidiary Guarantors, by execution of the Assumption Date
Supplemental Indenture, jointly and severally, guarantee to each Holder (i) the
due and punctual payment of the principal of and interest on each Note, when and
as the same shall become due and payable, whether at maturity, by acceleration
or otherwise, the due and punctual payment of interest on the overdue principal
of and interest on the Notes, to the extent lawful, and the due and punctual
payment of all other obligations and due and punctual performance of all
obligations of the Company to the Holders or the Trustee all in accordance with
the terms of such Note, this Indenture and the Registration Rights Agreement,
and (ii) in the case of any extension of time of payment or renewal of any Notes
or any of such other obligations, that the same will be promptly paid in full
when due or performed in accordance with the terms of the extension or renewal,
at stated maturity, by acceleration or otherwise. From and after the Assumption
Date, each Subsidiary Guarantor, by execution of the Assumption Date
Supplemental Indenture, agrees that its obligations hereunder shall be absolute
and unconditional, irrespective of, and shall be unaffected by, any invalidity,
irregularity or unenforceability of any such Note or this Indenture, any failure
to enforce the provisions of any such Note, this Indenture or the Registration
Rights Agreement, any waiver, modification or indulgence granted to the Company
with respect thereto by the Holder of such Note, or any other circumstances
which may otherwise constitute a legal or equitable discharge of a surety or
such Subsidiary Guarantor.

          Each Subsidiary Guarantor hereby waives diligence, presentment, demand
for payment, filing of claims with a court in the event of merger or bankruptcy
of the Company, any right to require a proceeding first against the Company,
protest or notice with respect to any such Note or the Indebtedness evidenced
thereby and all demands whatsoever, and covenants that this Guarantee will not
be discharged as to any such Note except by payment in full of the principal
thereof and interest thereon. Each Subsidiary Guarantor hereby agrees that, as
between such Subsidiary Guarantor, on the one hand, and the Holders and the
Trustee, on the other hand, (i) the maturity of the obligations guaranteed
hereby may be accelerated as provided in Article Six for the purposes of this
Guarantee, notwithstanding any stay, injunction or other prohibition preventing
such acceleration in respect of the obligations guaranteed hereby, and (ii) in
the event of any declaration of acceleration of such obligations as provided in
Article Six, such obligations (whether or not due and payable) shall forthwith
become due and payable by each Subsidiary Guarantor for the purpose of this
Guarantee.

<Page>

                                      -97-

          The Subsidiary Guarantors shall have the right to seek contribution
from any non-paying Subsidiary Guarantor so long as the exercise of such right
does not impair the rights of any Holder under the Subsidiary Guarantees.

SECTION 10.02. EXECUTION AND DELIVERY OF SUBSIDIARY GUARANTEE.

          To further evidence the Subsidiary Guarantee set forth in Section
10.01, each Subsidiary Guarantor hereby agrees, on the Assumption Date, that a
notation of such Subsidiary Guarantee, substantially in the form included in
EXHIBIT F hereto, shall be endorsed on each Note authenticated and delivered by
the Trustee on the Assumption Date and such Subsidiary Guarantee shall be
executed by either manual or facsimile signature of an Officer or an Officer of
a general partner, as the case may be, of each Subsidiary Guarantor. The
validity and enforceability of any Guarantee shall not be affected by the fact
that it is not affixed to any particular Note.

          Each of the Subsidiary Guarantors hereby agrees that its Guarantee set
forth in Section 10.01 shall be in full force and effect notwithstanding any
failure to endorse on each Note a notation of such Guarantee.

          If an Officer of a Subsidiary Guarantor whose signature is on this
Indenture or a Guarantee no longer holds that office at the time the Trustee
authenticates the Note on which such Guarantee is endorsed or at any time
thereafter, such Subsidiary Guarantor's Guarantee of such Note shall be valid
nevertheless.

          The delivery of any Note by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of any Guarantee set forth in
this Indenture on behalf of the Subsidiary Guarantor.

SECTION 10.03. RELEASE OF SUBSIDIARY GUARANTORS.

          The Guarantee of any Subsidiary Guarantor will be automatically and
unconditionally released and discharged upon any of the following:

     (A)  any transfer, to any Person not an Affiliate of the Company, of all of
          the Capital Stock held by the Company or any of its Restricted
          Subsidiaries in such Subsidiary Guarantor (which transfer is made in
          accordance with this Indenture and, if the Company or any of its
          Restricted Subsidiaries intends to comply with Section 4.12 by making
          an investment or expenditure in Replacement Assets, the Company or
          such Restricted Subsidiary delivers to the Trustee a written agreement
          that it will make such investment or expenditure within the time frame
          set forth in Section 4.12); or

                                      -98-

     (B)  the designation of such Subsidiary Guarantor as an Unrestricted
          Subsidiary in accordance with the provisions of this Indenture;

and in each such case, the Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to such transactions have been complied
with and that such release is authorized and permitted hereunder.

          The Trustee shall execute any documents reasonably requested by either
the Company or a Subsidiary Guarantor in order to evidence the release of such
Subsidiary Guarantor from its obligations under its Guarantee endorsed on the
Notes and under this Article Ten.

SECTION 10.04. WAIVER OF SUBROGATION.

          Each Subsidiary Guarantor hereby irrevocably waives any claim or other
rights which it may now or hereafter acquire against the Company that arise from
the existence, payment, performance or enforcement of such Subsidiary
Guarantor's obligations under its Guarantee and this Indenture, including,
without limitation, any right of subrogation, reimbursement, exoneration,
indemnification, and any right to participate in any claim or remedy of any
Holder of Notes against the Company, whether or not such claim, remedy or right
arises in equity, or under contract, statute or common law, including, without
limitation, the right to take or receive from the Company, directly or
indirectly, in cash or other property or by set-off or in any other manner,
payment or Note on account of such claim or other rights. If any amount shall be
paid to any Subsidiary Guarantor in violation of the preceding sentence and the
Notes shall not have been paid in full, such amount shall have been deemed to
have been paid to such Subsidiary Guarantor for the benefit of, and held in
trust for the benefit of, the Holders of the Notes, and shall forthwith be paid
to the Trustee for the benefit of such Holders to be credited and applied upon
the Notes, whether matured or unmatured, in accordance with the terms of this
Indenture. Each Subsidiary Guarantor acknowledges that it will receive direct
and indirect benefits from the financing arrangements contemplated by this
Indenture and that the waiver set forth in this Section 10.06 is knowingly made
in contemplation of such benefits.

SECTION 10.05. NOTICE TO TRUSTEE.

          The Company or any Subsidiary Guarantor shall give prompt written
notice to the Trustee of any fact known to the Company or any such Subsidiary
Guarantor which would prohibit the making of any payment to or by the Trustee at
its Corporate Trust Office in respect of the Guarantees. Notwithstanding the
provisions of this Article Ten or any other provision of this Indenture, the
Trustee shall not be charged with knowledge of the existence of any facts which
would prohibit the making of any payment to or by the Trustee in respect of

<Page>

                                      -99-

the Guarantees, unless and until the Trustee shall have received written notice
thereof from the Company no later than one Business Day prior to such payment;
and, prior to the receipt of any such written notice, the Trustee, subject to
the provisions of this Section 10.05, and subject to the provisions of Sections
7.01 and 7.02, shall be entitled in all respects to assume that no such facts
exist; PROVIDED, HOWEVER, that if the Trustee shall not have received the notice
referred to in this Section 10.07 at least one Business Day prior to the date
upon which by the terms hereof any such payment may become payable for any
purpose under this Indenture (including, without limitation, the payment of the
principal of, premium, if any, or interest on any Note), then, anything herein
contained to the contrary notwithstanding, the Trustee shall have full power and
authority to receive such money and to apply the same to the purpose for which
such money was received and shall not be affected by any notice to the contrary
which may be received by it less than one Business Day prior to such date.

                                 ARTICLE ELEVEN

be done all such acts and things as may be necessary or proper, or as may be
required by the provisions of the Security Documents, to assure and confirm to
the Trustee, the Collateral Agent and the Collateral Trustee the security
interest in the Collateral contemplated hereby, by the Security Documents or any
part thereof, as from time to time constituted, so as to render the same
available for the security and benefit of this Indenture and of the Notes
secured thereby, according to the intent and purposes herein and therein
expressed. The Company shall take, upon request of the Trustee, any and all
actions

Mortgages and any instruments of further assurance, in such manner and in such
places as may be required by law fully to preserve and protect the rights of the

mortgage recording, registration and/or filing fees, charges and taxes relating
to this Indenture and the Security Documents, any amendments thereto and any
other instruments of further assurance required hereunder or pursuant to the

Collateral Agent, as the case may be, to take all actions it deems necessary or
appropriate in order to (a) enforce any of the terms of the Security Documents

obligations of the Company hereunder. The Trustee shall have power to institute
and maintain such suits and proceedings as it may deem expedient to prevent any
impairment of the Collateral by any acts that may be unlawful or in violation of
the Security Documents or this Indenture, and such suits and proceedings as the
Trustee may deem expedient to preserve or protect its interests and the
interests of the Holders in the Collateral (including power to institute and
maintain suits or proceedings to restrain the enforcement of or compliance with
any legislative or other governmental enactment, rule or order that may be
unconstitutional or otherwise invalid if the enforcement of, or compliance with,
such enactment, rule or order would impair the security interest hereunder or be
prejudicial to the interests of the Holders or to the Trustee).

                            [FORM OF REVERSE OF NOTE]

                                SOI FUNDING CORP.

                       11.25% SENIOR SECURED NOTE DUE 2009

          1.   INTEREST. SOI FUNDING CORP., a Delaware corporation, as issuer
(the "COMPANY"), promises to pay, until the principal hereof is paid or made
available for payment, interest on the principal amount set forth on the face
hereof at a rate of 11.25% per annum. Interest hereon will accrue from and
including the most recent date to which interest has been paid or, if no
interest has been paid, from and including July 9, 2002 to but excluding the
date on which interest is paid. Interest shall be payable in arrears on each
July 15 and January 15, commencing July 15, 2003. Interest will be computed on
the basis of a 360-day year of twelve 30-day months and actual days elapsed. The
Company shall pay interest on overdue principal and on overdue interest (to the
full extent permitted by law) at the rate borne by the Notes.

          2.   METHOD OF PAYMENT. The Company will pay interest hereon (except
defaulted interest) to the Persons who are registered Holders at the close of
business on June 30 or December 31 next preceding the interest payment date
(whether or not a Business Day). Holders must surrender Notes to a Paying Agent
to collect principal payments. The Company will pay principal and interest in
money of the United States of America that at the time of payment is legal
tender for payment of public and private debts. Interest may be paid by check
mailed to the Holder entitled thereto at the address indicated on the register
maintained by the Registrar for the Notes.

          3.   PAYING AGENT AND REGISTRAR. Initially, HSBC Bank USA (the
"TRUSTEE") will act as a Paying Agent and Registrar. The Company may change any
Paying Agent or Registrar without notice. Neither the Company nor any of its
Affiliates may act as Paying Agent or Registrar.

          4.   INDENTURE. The Company issued the Notes under an Indenture dated
as of July 9, 2002 (the "INDENTURE") between the Company and the Trustee. This
is one of an issue of Notes of the Company issued, or to be issued, under the
Indenture. The terms of the Notes include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939
(15 U.S. Code Sections 77aaa-77bbbb), as amended from time to time. The Notes
are subject to all such terms, and Holders are referred to the Indenture and
such Act for a statement of them. Capitalized and certain other terms used
herein and not otherwise defined have the meanings set forth in the Indenture.

          5.   OPTIONAL REDEMPTION. (a) At any time on or prior to July 15,
2005, the Company may at its option on any one or more occasions redeem Notes
(including Additional Notes, if any) in an aggregate principal amount not to
exceed 35% of the aggregate principal

                                       A-4
<Page>

amount of Notes (including Additional Notes, if any) issued under the Indenture
at a redemption price of 111.250% of the principal amount, plus accrued and
unpaid interest, if any, to the redemption date, with the net cash proceeds of
one or more Public Equity Offerings; PROVIDED that:

          (1)  at least 65% of the aggregate principal amount of Notes
     (including Additional Notes, if any) issued under the Indenture remains
     outstanding immediately after the occurrence of such redemption (excluding
     Notes held by the Company and its Subsidiaries); and

          (2)  the redemption occurs within 90 days of the date of the closing
     of such Public Equity Offering.

          (b)  The Trustee will select Notes called for redemption pursuant to
this paragraph 5 on a PRO RATA basis, by lot or by such method as the Trustee
shall deem fair and appropriate; PROVIDED that no Notes of $1,000 or less shall
be redeemed in part. A new Note in principal amount equal to the unredeemed
portion thereof will be issued in the name of the Holder thereof upon
cancellation of the original Note. Notes called for redemption pursuant to this
paragraph 5 become due on the date fixed for redemption. On and after the
redemption date, interest stops accruing on Notes or portions of them called for
redemption.

          6.   SPECIAL MANDATORY REDEMPTION. In the event that the Solutia
Assumption does not occur on or prior to the Deadline, the Company will, on a
day not more than 20 days following the Deadline (the "SPECIAL MANDATORY
REDEMPTION DATE") redeem all of the Notes (the "SPECIAL MANDATORY REDEMPTION")
at a redemption price equal to the sum of (a) $206,702,624.80 (which amount is
equal to 103% of the original issue amount of the Units ($200,682,160.00)) plus
(b) the accrued and unpaid interest on the Notes from and including the Issue
Date to but excluding the Special Mandatory Redemption Date. The "DEADLINE" is
August 9, 2002 or such earlier time that Solutia determines not to refinance its
Credit Facility in accordance with the refinancing plan described in the
Offering Memorandum.

          7.   NOTICE OF REDEMPTION. Except in the case of Special Mandatory
Redemption, notices of redemption shall be mailed by first class mail at least
30 but not more than 60 days before the redemption date to each Holder of Notes
to be redeemed at its registered address. Notices of redemption may not be
conditional. If any Note is to be redeemed in part only, the notice of
redemption that relates to such Note shall state the portion of the principal
amount thereof to be redeemed. Notice of the Special Mandatory Redemption will
be mailed promptly to each Holder of Notes at its registered address, the
Trustee and the Securities Intermediary.

          8.   OFFERS TO PURCHASE. The Indenture provides that upon the
occurrence of a Change of Control or an Asset Sale and subject to further
limitations contained therein,

                                       A-5
<Page>

the Company shall make an offer to purchase outstanding Notes in accordance with
the procedures set forth in the Indenture.

          9.   REGISTRATION RIGHTS. (a) Pursuant to an Exchange and Registration
Rights Agreement among Solutia, from and after the Solutia Assumption, the
Subsidiary Guarantors and the Initial Purchasers named therein (the
"REGISTRATION RIGHTS AGREEMENT"), Solutia will be obligated to consummate an
exchange offer pursuant to which the Holder of this Note shall have the right to
exchange this Note for Notes which have been registered under the Securities
Act, in like principal amount and having substantially identical terms as the
Notes. (b) If (i) within 60 days after the Assumption Date, neither the Exchange
Offer Registration Statement nor the Shelf Registration Statement has been filed
with the Commission; (ii) within 120 days after the Assumption Date, the
Exchange Offer Registration Statement or the Shelf Registration Statement, as
applicable, has not been declared effective; (iii) within 150 days after the
Assumption Date, the Exchange Offer has not been consummated; or (iv) after
either the Exchange Offer Registration Statement or the Shelf Registration
Statement has been declared effective, such Registration Statement thereafter
ceases to be effective or usable (subject, in the case of the Shelf Registration
Statement, to the exceptions set forth in the Registration Rights Agreement) in
connection with resales of the Initial Placement or Exchange Securities in
accordance with and during the periods specified in Sections 2 and 3 of the
Registration Rights Agreement (each such event referred to in clauses (i)
through (iv), a "REGISTRATION DEFAULT"), liquidated damages ("LIQUIDATED
DAMAGES") will accrue on the Initial Placement and the Exchange Securities from
and including the date on which any such Registration Default shall occur to but
excluding the date on which all Registration Defaults have been cured.
Liquidated Damages will accrue at a rate equal to 0.25% per annum of the
aggregate principal amount of the Notes during the 90-day period immediately
following the occurrence of any Registration Default and shall increase by 0.25%
per annum for each subsequent 90-day period during which such Registration
Default continues, but in no event shall such Liquidated Damages exceed 1.00%
per annum.

          10.  DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered
form without coupons in denominations of $1,000 and integral multiples of
$1,000. A Holder may transfer or exchange Notes in accordance with the
Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay to it any taxes and
fees required by law or permitted by the Indenture. The Registrar need not
register the transfer of or exchange any Notes or portion of a Note selected for
redemption, or register the transfer of or exchange any Notes for a period of 15
days before a mailing of notice of redemption.

          11.  PERSONS DEEMED OWNERS. The registered Holder of this Note may be
treated as the owner of this Note for all purposes.

          12.  UNCLAIMED MONEY. If money for the payment of principal or
interest remains unclaimed for two years, the Trustee will pay the money back to
the Company at its

                                       A-6
<Page>

written request. After that, Holders entitled to the money must look to the
Company for payment as general creditors unless an "abandoned property" law
designates another Person.

          13.  AMENDMENT, SUPPLEMENT, WAIVER, ETC. The Company, the Subsidiary
Guarantors, if any, and the Trustee (if a party thereto) may, without the
consent of the Holders of any outstanding Notes, amend, waive or supplement the
Indenture or the Notes for certain specified purposes, including, among other
things, curing ambiguities, defects or inconsistencies, maintaining the
qualification of the Indenture under the Trust Indenture Act of 1939, as
amended, providing for the assumption by a successor to the Company of its
obligations under the Indenture or any Security Documents and making any change
that does not materially and adversely affect the rights of any Holder. Other
amendments and modifications of the Indenture or the Notes may be made by the
Company, the Subsidiary Guarantors, if any, and the Trustee with the consent of
the Holders of not less than a majority of the aggregate principal amount of the
outstanding Notes, subject to certain exceptions requiring the consent of the
Holders of the particular Notes to be affected.

          14.  RESTRICTIVE COVENANTS. The Indenture imposes certain limitations
on the ability of the Company and its Restricted Subsidiaries to, among other
things, incur additional Indebtedness, pay dividends on, redeem or repurchase
its Capital Stock, make certain investments, sell assets, create restrictions on
the payment of dividends or other amounts to the Company from its Restricted
Subsidiaries, enter into transactions with Affiliates, expand into unrelated
businesses, create liens, enter into sale and leaseback transactions or
consolidate, merge or sell all or substantially all of the assets of the Company
and its Restricted Subsidiaries and requires the Company to provide reports to
Holders of the Notes. Such limitations are subject to a number of important
qualifications and exceptions. Pursuant to Section 4.06 of the Indenture, the
Company must annually report to the Trustee on compliance with such limitations.

          15.  SUCCESSOR CORPORATION. When a successor corporation assumes all
the obligations of its predecessor under the Notes and the Indenture and the
transaction complies with the terms of Article Five of the Indenture, the
predecessor corporation will, except as provided in Article Five, be released
from those obligations.

          16.  DEFAULTS AND REMEDIES. Events of Default are set forth in the
Indenture. Subject to certain limitations in the Indenture, if an Event of
Default (other than an Event of Default specified in Section 6.01(7) of the
Indenture with respect to the Company or any Subsidiary Guarantor, if any)
occurs and is continuing, then, and in each and every such case, either the
Trustee, by notice in writing to the Company, or the Holders of not less than
25% of the principal amount of the Notes then outstanding, by notice in writing
to the Company and the Trustee, may, and the Trustee at the request of such
Holders shall, declare due and payable, if not already due and payable, the
principal of and any accrued and unpaid interest on all of the Notes; and upon
any such declaration all such amounts upon such Notes shall become and be
immediately due and payable, anything in the Indenture or in the Notes to the

                                       A-7
<Page>

contrary notwithstanding. If an Event of Default specified in Section 6.01(7) of
the Indenture occurs with respect to the Company or any Subsidiary Guarantor,
then the principal of and any accrued and unpaid interest on all of the Notes
shall immediately become due and payable without any declaration or other act on
the part of the Trustee or any Holder. Holders may not enforce the Indenture or
the Notes except as provided in the Indenture. The Trustee may require indemnity
satisfactory to it before it enforces the Indenture or the Notes. Subject to
certain limitations, Holders of a majority in principal amount of the then
outstanding Notes may direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from Holders notice of any continuing default (except a
default in payment of principal, premium, if any, or interest on the Notes or a
default in the observance or performance of any of the obligations of the
Company under Article Five of the Indenture) if it determines that withholding
notice is in their best interests.

          17.  TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or
any other capacity, may make loans to, accept deposits from, and perform
services for the Company or its Affiliates, and may otherwise deal with the
Company or its Affiliates, as if it were not Trustee.

          18.  NO RECOURSE AGAINST OTHERS. No past, present or future director,
officer, employee, incorporator, agent, member or stockholder or Affiliate of
the Company, as such, shall have any liability for any obligations of the
Company under the Notes, the Indenture or for any claim based on, in respect of,
or by reason of, such obligations or their creation. No past, present or future
director, officer, employee, incorporator, agent or stockholder or Affiliate of
any of the Subsidiary Guarantors, as such, shall have any liability for any
obligations of the Subsidiary Guarantors under the Guarantees, the Indenture or
for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder of Notes and Guarantees by accepting a Note and a
Guarantee waives and releases all such liabilities. The waiver and release are
part of the consideration for issuance of the Notes and the Guarantees.

          19.  DISCHARGE. The Company's obligations pursuant to the Indenture
will be discharged, except for obligations pursuant to certain sections thereof,
subject to the terms of the Indenture, upon the payment of all the Notes or upon
the irrevocable deposit with the Trustee of United States dollars or U.S.
Government Obligations sufficient to pay when due principal of and interest on
the Notes to maturity or redemption, as the case may be.

          20.  GUARANTEES. From and after the Solutia Assumption Date, the Note
will be entitled to the benefits of certain Guarantees made for the benefit of
the Holders. Reference is hereby made to the Indenture for a statement of the
respective rights, limitations of rights, duties and obligations thereunder of
the Subsidiary Guarantors, the Trustee and the Holders.

          21.  AUTHENTICATION. This Note shall not be valid until the Trustee
signs the certificate of authentication on the other side of this Note.

                                       A-8

          22.  GOVERNING LAW. THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, BUT WITHOUT GIVING EFFECT TO
APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF
THE LAW OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY. The Trustee, the
Company and the Subsidiary Guarantors agree to submit to the jurisdiction of the
courts of the State of New York in any action or proceeding arising out of or
relating to the Indenture or the Notes.

delivery of this Supplemental Indenture by Solutia, SOI Funding, the Subsidiary
Guarantors and the Trustee, the Indenture shall be supplemented in accordance
herewith, and this Supplemental Indenture shall form a part of the Indenture for
all purposes, and every Holder of Securities heretofore or hereafter
authenticated and delivered under the Indenture shall be bound thereby.
Notwithstanding any other provision of this Supplemental Indenture, this
Supplemental Indenture shall not be deemed to be effective unless and until the
Securities Intermediary (as defined in the Escrow Agreement) releases the
Solutia Amount (as defined in the Escrow Agreement) out of the Escrow Funds to
Solutia (or its designee) pursuant to Section 3(a) of the Escrow Agreement. In
the event that the Securities Intermediary does not so release the Solutia
Amount, this Supplemental Indenture shall automatically terminate and never take
force or effect.

supplemented hereby, all provisions in the Indenture shall remain in full force
and effect.

implementation of the

Indenture, and the Indenture and this Supplemental Indenture shall henceforth be
read and construed together.

          Section 2.4.  CONFIRMATION AND PRESERVATION OF INDENTURE. The
Indenture as supplemented by this Supplemental Indenture is in all respects
confirmed and preserved.

          Section 2.5.  CONFLICT WITH TRUST INDENTURE ACT. If any provision of
this Supplemental Indenture limits, qualifies or conflicts with any provision of
the TIA that is required or deemed under the TIA to be part of and govern any
provision of this Supplemental Indenture, such provision of the TIA shall
control. If any provision of this Supplemental Indenture modifies or excludes
any provision of the TIA that may be so modified or excluded, the provision of
the TIA shall be deemed to apply to the Indenture as so modified or to be
excluded by this Supplemental Indenture, as the case may be.

          Section 2.6.  SEVERABILITY. In case any provision in this Supplemental
Indenture shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

          Section 2.7.  BENEFITS OF SUPPLEMENTAL INDENTURE. Nothing in this
Supplemental Indenture or the Securities, express or implied, shall give to any
Person, other than the parties hereto and thereto and their successors hereunder
and thereunder and the Holders of the Securities, any benefit of any legal or
equitable right, remedy or claim under the Indenture, this Supplemental
Indenture or the Securities.

          Section 2.8.  SUCCESSORS. All agreements of Solutia in this
Supplemental Indenture shall bind its successors. All agreements of the Trustee
in this Supplemental Indenture shall bind its successors.

          Section 2.9.  CERTAIN DUTIES AND RESPONSIBILITIES OF THE TRUSTEE. In
entering into this Supplemental Indenture, the Trustee shall be entitled to the
benefit of every provision of the Indenture and the Securities relating to the
conduct or affecting the liability or affording protection to the Trustee,
whether or not elsewhere herein so provided.

          Section 2.10. GOVERNING LAW. This Supplemental Indenture shall be
governed by, and construed in accordance with, the laws of the State of New York
but without giving effect to applicable principles of conflicts of law to the
extent that the application of the laws of another jurisdiction would be
required thereby.

          Section 2.11. MULTIPLE ORIGINALS. The parties may sign any number of
copies of this Supplemental Indenture, each of which shall be deemed an
original, but all of which together shall constitute one and the same
instrument.

inserted for convenience of reference only, are not intended to be considered a
