--------

                  (b) Warrants sold in offshore transactions in reliance on

beneficial interests in the Regulation S Permanent Global Warrants may be
transferred to a person that takes delivery in the form of an interest in
the Global Warrants and (ii) beneficial interests in the Global Warrants may
be transferred to a person that takes delivery in the form of an interest in
the Regulation S Permanent Global Warrants, provided, in each case, that the
                                            --------
certification requirements described in Section 6 hereof are complied with.

Assistant Treasurer or Chief Financial Officer and by a Vice President, its

any of the Warrant Certificates shall cease to be such officer before the
Warrant Certificates so signed shall have been countersigned by the Warrant
Agent, or disposed of by the Company, such Warrant Certificates nevertheless
may be countersigned and delivered or disposed of as though such person had
not ceased to be such officer of the Company; and any Warrant Certificate
may be signed on behalf of the Company by any person who, at the actual date
of the execution of such Warrant Certificate, shall be a proper officer of
the Company to sign such Warrant Certificate, although at the date of the
execution of this Warrant Agreement any such person was not such officer.

                  Warrant Certificates shall be dated the date of
countersignature by the Warrant Agent.

maintained at the principal office of the Warrant Agent in the Borough of
Manhattan, City of New York (the "Warrant Register") as they are issued.
                                  ----------------

countersigned. The Warrant Agent shall, upon written instructions of the
Chairman of the Board, the President, Chief Executive Officer, a Vice
President, the Treasurer, an Assistant Treasurer, Chief Financial Officer,

of Depositary. If at any time:
-------------

                  (i)      the Depositary for the Global Warrants notifies
                           the Company that the Depositary is unwilling or
                           unable to continue as Depositary for the Global
                           Warrants and a successor Depositary for the
                           Global Warrant is not appointed by the Company
                           within 90 days after delivery of such notice; or

                 (ii)      the Company, at its sole discretion, notifies the
                           Warrant Agent in writing that it elects to cause
                           the issuance of Definitive Warrants for all
                           Global Warrants under this Agreement,

then the Company will execute, and the Warrant Agent will, upon receipt of
an Officers' Certificate requesting the countersignature and delivery of
Definitive Warrants, countersign and deliver Definitive Warrants, in an
aggregate number equal to the aggregate number of Warrants represented by
the Global Warrant, in exchange for such Global Warrant.

                  (g)      Cancellation or Adjustment of a Global Warrant.
                           ----------------------------------------------
At such time as all beneficial interests in a Global Warrant have either
been exchanged for Definitive Warrants, redeemed, repurchased or canceled,
such Global Warrant shall be returned to the Company or, upon written order
to the Warrant Agent in the form of an Officers' Certificate from the
Company, retained and canceled by the Warrant Agent. At any time prior to
such cancellation, if any beneficial interest in a Global Warrant is
exchanged for Definitive Warrants, redeemed, repurchased or canceled, the
number of Warrants represented by such Global Warrant shall be reduced and
an endorsement shall be made on such Global Warrant by the Warrant Agent to
reflect such reduction.

                  (i)      To permit registrations of transfers and
                           exchanges, the Company shall execute, at the

                           shall authenticate Definitive and Global
                           Warrants.

                 (ii)      All Definitive and Global Warrants issued upon
                           any registration, transfer or exchange of
                           Definitive and Global Warrants shall be the valid

                           whose name any Warrant is registered as the
                           absolute owner of such Warrant, and neither the
                           Warrant Agent nor the Company shall be affected
                           by notice to the contrary.

                  SECTION 7. Terms of Warrants; Exercise of Warrants.
                             ---------------------------------------
Subject to the terms of this Agreement each Warrantholder shall have the
right, which may be exercised commencing on or after the Separation Date and
until the earlier of (1) the Deadline (as defined in the Indenture) if the
Solution Assumption has not been consummated on or before such date or
(2) 5:00 p.m., New York City time, on July 15, 2009 (the "Expiration Date"),
                                                          ---------------
to receive from the Company upon the exercise of each Warrant the number of
fully paid and nonassessable Warrant Shares which the holder may at the time
be entitled to receive on exercise of such Warrants and payment of the
Exercise Price (as defined) for such Warrant Shares. Each Warrant not
exercised prior to the Expiration Date shall become void and all rights
thereunder and all rights in respect thereof under this Agreement shall
cease as of such time. No adjustments as to dividends will be made upon
exercise of the Warrants.

                  The price per share at which Warrant Shares shall be
purchasable upon exercise of Warrants (the "Exercise Price") shall be equal
                                            --------------
to $7.59, subject to adjustment pursuant to Section 13. A Warrant may be
exercised upon surrender at the office or agency of the Company maintained
for such purpose, which initially will be at the principal office of the
Company, of the Warrant Certificate or Certificates evidencing the Warrants
to be exercised with the form of election to purchase on the reverse thereof
(the "Election to Exercise") duly filled in and signed, which signature
      --------------------
shall be guaranteed in accordance with the provisions set forth in the
Warrant Certificate.

                  The "Exercise Date" for a Warrant shall be the date when
                       -------------
all of the items referred to in the immediately preceding sentence and the
next paragraph are received by the Warrant Agent at or prior to 9 a.m.,
New York City time, on a Business Day and the exercise of the Warrants will
be effective as of such Exercise Date. If any items referred to in such
sentence are received after 11 a.m.,



<PAGE>
<PAGE>

                                    -12-


New York City time, on a Business Day, the exercise of the Warrants to which
such item relates will be effective on the next succeeding Business Day.
Notwithstanding the foregoing, in the case of an exercise of Warrants on the
Expiration Date, if all of the items referred to in such sentence are
received by the Warrant Agent at or prior to 5 p.m., New York City time, on
the Expiration Date, the exercise of the Warrants to which such items relate
will be effective on the Expiration Date.

                  The Warrants may be exercised by surrendering to the
Company the Warrants to be exercised with the accompanying form of election
to purchase properly completed and executed, together with payment of the
Exercise Price. Payment of the Exercise Price may be made at the Holder's
election (i) in cash in United States dollars by wire transfer or by
certified or official bank check to the order of the Company or (ii) by the
surrender of one or more Warrant Certificates (and without the payment of
the Exercise Price in cash) in exchange for a number of shares of the
Company's Common Stock equal to the product of (a) the number of shares of
the Company's Common Stock for which such Warrant is exercisable as of the
Exercise Date (if the Exercise Price were being paid in cash), and (b) the
Cashless Exercise Ratio (the "Cashless Exercise"). The "Cashless Exercise
                              -----------------         -----------------
Ratio" shall equal a fraction, the numerator of which is the excess of the
-----
Current Market Value per share of the Company's Common Stock on the Exercise
Date over the Exercise Price per share as of the Exercise Date and the
denominator of which is the Current Market Value per share of the Company's
Common Stock on the Exercise Date. Upon surrender of a Warrant Certificate
representing more than one Warrant, the number of shares of Common Stock
deliverable upon a Cashless Exercise shall be equal to the product of the
number of shares of the Company's Common Stock issuable in respect of those
Warrants that the Holder specifies are to be exercised pursuant to a
Cashless Exercise multiplied by the Cashless Exercise Ratio. All provisions
of this Agreement are applicable with respect to an exercise of a Warrant
Certificate pursuant to a Cashless Exercise for less than the full number of
Warrants represented thereby.

                  "Current Market Value" per share of any class of Common
                   --------------------
Stock of the Company at any date shall mean:

                  (1) if no class of Common Stock is then registered under
         the Exchange Act and traded on a national securities exchange or on
         the Nasdaq National Market System,

                           (a) the value of such class of Common Stock,
                  determined in good faith by the board of directors of the
                  Company and certified in a board resolution, taking into
                  account the most recently completed arms-length
                  transaction between the Company and a Person other than an
                  Affiliate of the Company and the closing of which occurs
                  on such date or shall have occurred within the six-month
                  period preceding such date, or

                           (b) if no such transaction shall have occurred on
                  such date or within such six-month period, the fair market
                  value of the security as determined by a nationally
                  recognized Independent Financial Expert; provided,
                                                           --------
                  however, that, in the case of the calculation of Current
                  -------
                  Market Value for determining the cash value of fractional
                  shares, any such determination within six months that is,
                  in the good faith judgment of the board of directors, a
                  reasonable determination of value may be utilized, or

                  (2)      (a) if any class of Common Stock is then registered
                  under the Exchange Act and traded on a national securities
                  exchange or on the Nasdaq National Market System, the
                  average of the daily closing sales prices of such class of
                  Common Stock for the 20 consecutive trading days
                  immediately preceding such date, or

                           (b) if such class of Common Stock has been
                  registered under the Exchange Act and traded on a national
                  securities exchange or on the Nasdaq National Market
                  System for less than 20 consecutive trading days before
                  such date, then the average of the daily closing sales
                  prices for all of the trading days before such date for
                  which closing sales prices are available, in the case of
                  each of (2)(a) and (2)(b), as certified to the Warrant
                  Agent by the Chief Executive Officer, the President, any
                  Executive Vice President or the Chief Financial Officer or
                  Treasurer of the Company. The closing sales price of each
                  such trading day shall be the closing sales price, regular
                  way, on such day or, if no sale takes place on such day,
                  the average of the closing bid and asked prices on such
                  day.

                  Subject to the provisions of Section 6 hereof, upon such
surrender of Warrants, the Company shall issue and cause to be delivered
with all reasonable dispatch to or upon the written order of the Holder and
in such name or names as the Warrantholder may designate a certificate or
certificates for the number of Warrant Shares issuable upon the exercise of
such Warrants. Such certificate or certificates shall be deemed to have been
issued and any Person so designated to be named therein shall be deemed to
have become a holder of record of such Warrant Shares as of the Exercise
Date. At the election of the Company with the consent of the holder of
record of the relevant Warrant Shares, Warrant Shares may initially be
issued in global form (the "Global Shares"). Such Global Shares shall
                            -------------
represent such of the outstanding Warrant Shares as shall be specified
therein and each Global Share shall provide that it represents the aggregate
amount of outstanding Warrant Shares from time to time endorsed thereon and
that the aggregate amount of outstanding Warrant Shares represented thereby
may from time to time be reduced or increased, as appropriate. Any
endorsement of a Global Share to reflect any increase or decrease in the
amount of outstanding Warrant Shares represented thereby shall be made by
the registrar for the Warrant Shares and the Depositary (referred to below)
in accordance with instructions given by the holder thereof. DTC shall (if
possible) act as the Depositary with respect to the Global Shares until a
successor shall be appointed by the Company and the registrar for the
Warrant Shares.

                  The Warrants shall be exercisable only in whole. In the
event that a certificate evidencing Warrants is exercised in respect of
fewer than all of the Warrants evidenced thereby at any time prior to the
date of expiration of the Warrants, a new certificate evidencing the
remaining Warrant or Warrants will be issued, and the Warrant Agent is
irrevocably authorized to countersign and to deliver the required new
Warrant Certificate or Certificates pursuant to this Agreement, and the
Company, whenever required by the Warrant Agent, will promptly supply the
Warrant Agent with Warrant Certificates duly executed on behalf of the
Company for such purpose. Holders of Warrants will be able to exercise their
Warrants only if a registration statement relating to the Warrant Shares
underlying the Warrants is then in effect, or the exercise of such Warrants
is exempt from the registration requirements of the Securities Act, and such
securities are qualified for sale or exempt from qualification under the
applicable securities laws of the states in which the various holders of
Warrants or



<PAGE>
<PAGE>

                                    -14-


other persons to whom it is proposed that Warrant Shares be issued on
exercise of the Warrants reside.

                  All Warrant Certificates surrendered upon exercise of
Warrants shall be canceled by the Warrant Agent. Such canceled Warrant
Certificates shall then be disposed of by the Warrant Agent in a manner
consistent with the Warrant Agent's customary procedure for such disposal
and in a manner reasonably satisfactory to the Company. The Warrant Agent
shall account promptly to the Company with respect to Warrants exercised.

                  The Warrant Agent shall keep copies of this Agreement and
any notices given or received hereunder available for inspection by the
Holders during normal business hours at its office. The Company shall supply
the Warrant Agent from time to time with such numbers of copies of this
Agreement as the Warrant Agent may request.

                  SECTION 8. Payment of Taxes. The Company will pay all
                             ----------------
documentary stamp taxes attributable to the initial issuance of Warrant
Shares upon the exercise of Warrants; provided, however, that the Company
                                      --------  -------
shall not be required to pay any tax or taxes which may be payable in
respect of any transfer involved in the issue of any Warrant Certificates or
any certificates for Warrant Shares in a name other than that of the
registered holder of a Warrant Certificate surrendered upon the exercise of
a Warrant, and the Company shall not be required to issue or deliver such
Warrant Certificates unless or until the Person or Persons requesting the
issuance thereof shall have paid to the Company the amount of such tax or
shall have established to the satisfaction of the Company that such tax has
been paid.

                  SECTION 9. Rules 144 and 144A. The Company covenants that
                             ------------------
it will file the reports required to be filed by it under the Securities Act
and the Exchange Act and the rules and regulations adopted by the SEC
thereunder in a timely manner in accordance with the requirements of the
Securities Act and the Exchange Act and, if at any time the Company is not
required to file such reports, it will, upon the request of any holder or
beneficial owner of warrants, make available such information necessary to
permit sales pursuant to Rule 144A under the Securities Act.

                  SECTION 10. Mutilated or Missing Warrant Certificates. In
                              -----------------------------------------
case any of the Warrant Certificates shall be mutilated, lost, stolen or
destroyed, the Company may at its discretion issue and the Warrant Agent may
countersign, in exchange and substitution for and upon cancellation of the
mutilated Warrant Certificate, or in lieu of and substitution for the
Warrant Certificate lost, stolen or destroyed, a new Warrant Certificate of
like tenor and representing an equivalent number of Warrants, but only upon
receipt of evidence satisfactory to the Company and the Warrant Agent of
such loss, theft or destruction of such Warrant Certificate and indemnity
also satisfactory to them.

                  SECTION 11. Reservation of Warrant Shares. The Company
                              -----------------------------
will at all times authorize and reserve and keep available, free from
preemptive rights and free from all taxes, liens, charges and security
interests, out of the aggregate of its authorized but unissued Common Stock
or its authorized and issued Common Stock held in its treasury, for the
purpose of enabling it to satisfy its obligation to issue Warrant Shares
upon exercise of Warrants, the maximum number of shares of Common Stock
which may then be deliverable upon the exercise of all outstanding Warrants.

                                    -15-


                  The Company or, if appointed, the transfer agent for the
Common Stock (the "Transfer Agent") and every subsequent transfer agent for
                   --------------
any shares of the Company's Capital Stock issuable upon the exercise of any
of the rights of purchase aforesaid will be irrevocably authorized and
directed at all times to reserve such number of authorized shares as shall
be required for such purpose. The Company will keep a copy of this Agreement
on file with the Transfer Agent and with every subsequent transfer agent for
any shares of the Company's Capital Stock issuable upon the exercise of the
rights of purchase represented by the Warrants. The Warrant Agent is hereby
irrevocably authorized to (1) instruct such Transfer Agent to make the
appropriate book entries and (2) requisition from time to time from such
Transfer Agent the stock certificates, if any, required to honor outstanding
Warrants upon exercise thereof, in each case in accordance with the terms of
this Agreement. The Company will supply such Transfer Agent with duly
executed certificates for such purposes, if necessary, and will provide or
otherwise make available any cash which may be payable as provided in
Section 14. The Company will furnish such Transfer Agent a copy of all
notices of adjustments and certificates related thereto transmitted to each
holder pursuant to Section 15 hereof.

                  The Company covenants that all Warrant Shares which may be
issued upon exercise of Warrants made in accordance with the terms of this
Agreement will, upon issuance, be duly and validly authorized and issued,
fully paid, nonassessable, free of preemptive rights and free from all
taxes, liens, charges and security interests with respect to the issuance
thereof. The Company will take no action to increase the par value of the
Common Stock to an amount in excess of the Exercise Price, and the Company
will not enter into any agreements inconsistent with the rights of Holders
hereunder. The Company will use its reasonable best efforts to obtain all
such authorizations, exemptions or consents from any public regulatory body
having jurisdiction thereof as may be necessary to enable the Company to
perform its obligations under this Agreement.

                  SECTION 12. Obtaining Stock Exchange Listings. The Company
                              ----------------------------------
will from time to time take all action which may be necessary so that the
Warrant Shares, immediately upon their issuance upon the exercise of
Warrants, will be listed on the principal securities exchanges and markets
within the United States of America (including the Nasdaq National Market
System), if any, on which the Company's Common Stock is then listed. In the
event that, at any time during the period in which the Warrants are
exercisable, the Common Stock is not listed on any principal securities
exchanges or markets within the United States of America, the Company will
use its best efforts to permit the Warrant Shares to be designated Portal
securities in accordance with the rules and regulations adopted by the
National Association of Securities Dealers, Inc. relating to trading in The
Portal Market.

                  SECTION 13. Adjustment of Exercise Rate and Exercise
                              ----------------------------------------
Price. The number of Warrant Shares purchasable upon the exercise of each
-----
Warrant (the "Exercise Rate") and the Exercise Price are subject to
              -------------
adjustment from time to time upon the occurrence of the events enumerated in
this Section 13. The Exercise Rate shall initially be 24.814 to 1.

                  (a)      Adjustment for Change in Capital Stock. If, after
                           --------------------------------------
the Issue Date, the Company:

                  (i)      pays a dividend or makes a distribution on shares of
         any class of its Common Stock payable in shares of its Common Stock
         or other Capital Stock of the Company (except



<PAGE>
<PAGE>

                                    -16-


         to the extent any such dividend results in the grant, issuance, sale
         or making of Distribution Rights or Distributions to holders of
         Warrants pursuant to Section 13(c));

                 (ii)      subdivides or splits any of its outstanding shares
         of any class of Common Stock into a greater number of shares;

                (iii)      combines any of its outstanding shares of Common
         Stock into a smaller number of shares; and

                 (iv)      issues by reclassification of any class of its
         Common Stock any shares of any of its Capital Stock,

then the Exercise Rate in effect immediately prior to such action for each
Warrant then outstanding shall be adjusted by multiplying the Exercise Rate
in effect immediately prior to such action by a fraction (A) the numerator
of which shall be the number of shares of Common Stock outstanding
immediately after such action and (B) the denominator of which shall be the
number of shares of Common Stock outstanding immediately prior to such
action or the record date applicable to such action, if any (regardless of
whether the Warrants then outstanding are then exercisable); and the
Exercise Price for each Warrant shall be adjusted to a number determined by
dividing the Exercise Price immediately prior to such event by such
fraction. The adjustment shall become effective immediately after the record
date in the case of a dividend or distribution and immediately after the
effective date in the case of a subdivision, combination or
reclassification. In the event that such dividend or distribution is not so
paid or made or such subdivision, combination or reclassification is not
effected, the Exercise Rate and Exercise Price shall again be adjusted to be
the Exercise Rate and Exercise Price which would then be in effect if such
record date or effective date had not been so fixed.

                  If after an adjustment a holder of a Warrant upon exercise
of such Warrant may receive shares of two or more classes of Capital Stock
of the Company, the Exercise Rate shall thereafter be subject to adjustment
upon the occurrence of an action taken with respect to any such class of
Capital Stock as is contemplated by this Section 13 with respect to the
Common Stock, on terms comparable to those applicable to Common Stock in
this Section 13.

                  (b)      Adjustment for Certain Sales of Common Stock
                           --------------------------------------------
Below Current Market Value. If, after the Issue Date, the Company (i) grants
--------------------------
or sells to any Affiliate of the Company (other than a subsidiary of the
Company) or (ii) grants, sells or offers to grant or sell to all holders of
Common Stock, any shares of Common Stock or any securities convertible into
or exchangeable or exercisable for Common Stock or of rights, options or
warrants entitling them to subscribe for the Company's Common Stock or
securities convertible into, or exchangeable or exercisable for, the
Company's Common Stock (other than (1) pursuant to the exercise of the
Warrants, (2) pursuant to any security convertible into, or exchangeable or
exercisable for, shares of Common Stock outstanding as of the Issue Date,
(3) upon the conversion, exchange or exercise of any convertible,
exchangeable or exercisable security as to which upon the issuance thereof
an adjustment pursuant to this Section 13 has been made or (4) upon the
conversion, exchange or exercise of convertible, exchangeable or exercisable
securities of the Company outstanding on the Issue Date (to the extent in
accordance with the terms of such securities as in effect on such date), at
a price below the then Current Market Value,

then the Exercise Rate for each Warrant then outstanding shall be adjusted
in accordance with the formula:

                           E1       =  E x      (O+N)
                                            --------------
                                            (O+(N x P/M))

and the Exercise Price shall be decreased (but not increased) in accordance
with the following formula:

                           EP1      =       EP x     E
                                                -------

where:

E1       =        the adjusted Exercise Rate for each Warrant then
                  outstanding;

E        =        the then current Exercise Rate for each Warrant
                  then outstanding;

EP       =        the then current Exercise Price per share for each
                  Warrant then outstanding;

EP1      =        the adjusted Exercise Price per share for each
                  Warrant then outstanding;

O        =        the number of shares of Common Stock outstanding
                  immediately prior to the sale of such Common Stock
                  or issuance of securities convertible, exchangeable
                  or exercisable for Common Stock;

N        =        the number of shares of Common Stock so sold or
                  the maximum stated number of shares of Common Stock
                  issuable upon the conversion, exchange or exercise
                  of any such convertible, exchangeable or
                  exercisable securities, as the case may be;

P        =        the proceeds per share of Common Stock received by
                  the Company, which (i) in the case of shares of Common
                  Stock is the amount received by the Company in
                  consideration for the sale and issuance of such
                  shares; and (ii) in the case of securities convertible
                  into or exchangeable or exercisable for shares of
                  Common Stock is the amount received by the Company in
                  consideration for the sale and issuance of such
                  convertible or exchangeable or exercisable securities,
                  plus the minimum aggregate amount of additional
                  consideration, other than the surrender of such
                  convertible or exchangeable securities, payable to
                  the Company upon exercise, conversion or exchange
                  thereof; and

M        =        the Current Market Value as of the Time of
                  Determination or at the time of sale, as the
                  case may be, of a share of Common Stock.

                  The adjustment shall become effective immediately after
the record date for the determination of shareholders entitled to receive
the rights, warrants or options to which this paragraph (b) applies or upon
consummation of the sale of Common Stock, as the case may be. To the extent

                                    -18-


that shares of Common Stock are not delivered after the expiration of such
rights, warrants or options, the Exercise Rate and Exercise Price for each
Warrant then outstanding shall be readjusted to the Exercise Rate and
Exercise Price which would otherwise be in effect had the adjustment made
upon the issuance of such rights, warrants or options been made on the basis
of delivery of only the number of shares of Common Stock actually delivered.
In the event that such rights, warrants or options are not so issued, the
Exercise Rate and Exercise Price for each Warrant then outstanding shall
again be adjusted to be the Exercise Rate and Exercise Price which would
then be in effect if such date fixed for determination of shareholders
entitled to receive such rights, warrants or options had not been so fixed.

                  No adjustment shall be made under this paragraph (b) if
the application of the formula stated above in this paragraph (a) would
result in a value of E1 that is lower than the value of E.

                  No adjustment shall be made under this paragraph (b) for
any adjustment which is the subject of paragraphs (a) and (e) of this
Section 13.

                  Notwithstanding the foregoing, no adjustment in the
Exercise Price or Exercise Rate will be required in respect of: (a) the
grant of any stock option or other stock incentive award pursuant to any
stock option or stock incentive plan or arrangement in effect on the Issue
Date or as disclosed in the Final Memorandum, (b) the grant of any stock
option or stock incentive award at an exercise price at least equal to the
then Current Market Value, (c) the grant of any other stock option or stock
incentive award to any officer, director or employee of the Company or any
of its Subsidiaries pursuant to any compensatory plan or arrangement that
has been approved by the Company's board of directors, or (d) the exercise
of any such option or award.

                  (c)      Adjustment upon Certain Distributions.

of Common Stock (whether in cash, property, evidences of indebtedness, or
otherwise), then the Exercise Rate shall be adjusted in accordance with the
formula:

and the Exercise Price shall be decreased (but not increased) in accordance
with the following formula:

                  assets distributable pursuant to such Distribution Rights
                  or Distribution per share of outstanding Common Stock.

                  The adjustment shall become effective immediately after
the Time of Determination with respect to the shareholders entitled to
receive the options, Convertible Securities, warrants, cash, property,
evidences of indebtedness or other securities or assets to which this
paragraph (c)(i) applies. No adjustment shall be made under this paragraph
(c) if the application of the formula stated above in this paragraph (c)(i)
would result in a value of E1 that is lower than the value of E. This
paragraph (c)(i) does not apply to any securities or distributions which
result in an adjustment pursuant to paragraphs (a) or (b) of this Section 13.

                 (ii)      Notwithstanding the provisions of paragraph (c)(i)
of this Section 13, cash dividends paid by the Company on its Common Stock in
the ordinary course of business that would otherwise give rise to an
adjustment pursuant to Section 13(c)(i) shall not give rise to such
adjustment to the extent such dividends do not exceed the lower of
(x) $10 million per calendar year and (y) $0.04 per share.

                 (iii)     Notwithstanding the provisions of paragraph (c)(i)
of this Section 13, an event which would otherwise give rise to an adjustment
pursuant to Section 13(c)(i) shall not give rise to such adjustment if the
Company grants, issues or sells Distribution Rights to the Holders of
Warrants or includes the holders of the Warrants in such Distribution, in
each case on a pro rata basis, assuming for the purpose of this Section
               --- ----
13(c)(ii) that (x) all outstanding shares of Common Stock are of one class
and (y) the Warrants had been exercised.

                 (iv)      Notwithstanding anything to the contrary set forth
in this Section 13(c), if, at any time, the Company makes any distribution
pursuant to any plan of liquidation (a "Liquidating Distribution") on shares
                                        ------------------------
of Common Stock (whether in cash, property, evidences of indebtedness or
otherwise), then, subject to applicable law, the Company shall make to each
Holder of Warrants the aggregate Liquidating Distribution which such Holder
would have acquired if such Holder had held the maximum number of shares of
Common Stock acquirable upon the complete exercise of each Holder's Warrants
(regardless of whether the Warrants are then exercisable) immediately before
the Time of Determination of shareholders entitled to receive Liquidating
Distributions.

                  (d)      Notice of Adjustment. Whenever the Exercise Rate
                           --------------------
and Exercise Price are adjusted, the Company shall promptly mail to holders
of Warrants then outstanding at the addresses appearing on the Warrant
Register a notice of the adjustments. The Company shall file with the
Warrant Agent and any other registrar such notice, an Officers' Certificate
and a certificate from the Company's independent public accountants briefly
stating the facts requiring the adjustment and the manner of computing it.
The certificates shall be conclusive evidence that the adjustment is
correct, absent manifest error and the Warrant Agent may rely conclusively
on anything contained in this certificate. Neither the Warrant Agent nor any
such registrar shall be under any duty or responsibility with respect to any
such certificate except to exhibit the same during normal business hours to
any holder desiring inspection thereof.

                  (e)      Reorganization of Company; Fundamental Transaction.
                           ---------------------------------------------------

                  (i)      If the Company, in a single transaction or through a
series of related transactions, consolidates with or merges with or into any
other person or sells, assigns, transfers, leases, conveys or otherwise
disposes of all or substantially all of its properties and assets to another
person or group of affiliated persons or is a party to a merger or binding
share exchange which reclassifies or changes its outstanding Common Stock (a
"Fundamental Transaction"), as a condition to consummating any such
 -----------------------
transaction the person formed by or surviving any such consolidation or
merger if other than the Company or the person to whom such transfer has
been made (the "Surviving Person") shall enter into a supplemental warrant
                ----------------
agreement. The supplemental warrant agreement shall provide (a) that the
holder of a Warrant then outstanding may exercise the Warrant for the kind
and amount of securities, cash or other assets which such holder would have
received immediately after the Fundamental Transaction if such holder had
exercised the Warrant immediately before the effective date of the
transaction (regardless of whether the Warrants are then exercisable and
without giving effect to the Cashless Exercise option), assuming (to the
extent applicable) that such holder (i) was not a constituent person or an
affiliate of a constituent person to such transaction, (ii) made no election
with respect thereto, and (iii) was treated alike with the plurality of
non-electing holders, and (b) that the Surviving Person shall succeed to and
be substituted to every right and obligation of the Company in respect of
this Agreement and the Warrants. The supplemental warrant agreement shall
provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Section 13. The
Surviving Person shall mail to holders of Warrants at the addresses
appearing on the Warrant Register a notice briefly describing the
supplemental warrant agreement. If the issuer of securities deliverable upon
exercise of Warrants is an affiliate of the Surviving Person, that issuer
shall join in the supplemental warrant agreement.

                 (ii)      Notwithstanding the foregoing, if the Company enters
into a Fundamental Transaction with another Person (other than a subsidiary
of the Company) and consideration is payable to holders of shares of Capital
Stock (or other securities or property) issuable or deliverable upon
exercise of the Warrants that are exercisable in exchange for such shares in
connection with such Fundamental Transaction which consideration consists
solely of cash assuming (to the extent applicable) that each such holder
(i) was not a constituent person or an affiliate of a constituent person to
such transaction, (ii) made no election with respect thereto, and (iii) was
treated alike with the plurality of non-electing holders, then the holders
of Warrants shall be entitled to receive distributions on the date of such
event on an equal basis with holders of such shares (or other securities
issuable upon

                                    -21-


exercise of the Warrants) as if the Warrants had been exercised immediately
prior to such event, less the aggregate Exercise Price therefor. Upon
receipt of such payment, if any, the rights of a holder of such Warrant
shall terminate and cease and such holder's Warrants shall expire.

                (iii)      If this paragraph (e) applies, it shall supersede
the application of paragraph (a) of this Section 13.

                  (f)      Other Events. If any event occurs as to which the
                           ------------
provisions of this Section 13 are not strictly applicable or, if strictly
applicable, would not, in the good faith judgment of the board of directors
of the Company, fairly and adequately protect the rights of the
Warrantholders in accordance with the essential intent and principles of
such provisions, then such board of directors shall make such adjustments in
the application of such provisions, in accordance with such essential intent
and principles, as shall be reasonably necessary, in the good faith opinion
of such board of directors, to protect such rights as aforesaid, but in no
event shall any such adjustment have the effect of decreasing the Exercise
Rate or decreasing the number of Warrant Shares issuable upon exercise of
the Warrants.

                  (g)      Company Determination Final. Any determination
                           ---------------------------
that the Company or the board of directors of the Company must make pursuant
to this Section 13 shall be conclusive, absent manifest error.

                  (h)      Warrant Agent's Adjustment Disclaimer. The
                           -------------------------------------
Warrant Agent shall have no duty to determine when an adjustment under this
Section 13 should be made, how it should be made or what it should be. The
Warrant Agent shall have no duty to determine whether a supplemental warrant
agreement under paragraph (e) need be entered into or whether any provisions
of any supplemental warrant agreement are correct. The Warrant Agent shall
not be accountable for and makes no representation as to the validity or
value of any securities or assets issued upon exercise of Warrants. The
Warrant Agent shall not be responsible for the Company's failure to comply
with this Section 13.

                  (i)      Specificity of Adjustment. Regardless of any
                           -------------------------
adjustment in the number or kind of shares purchasable upon the exercise of
the Warrants, Warrant Certificates theretofore or thereafter issued may
continue to express the same number and kind of Warrant Shares per Warrant
as are stated on the Warrant Certificates initially issuable pursuant to
this Agreement.

                  (j)      Voluntary Adjustment. The Company from time to
                           --------------------
time may increase the Exercise Rate by any number and for any period of
time; provided, however, that such period is not less than 20 Business Days.
      --------  -------
Whenever the Exercise Rate is so increased, the Company shall mail to
holders at the addresses appearing on the Warrant Register and file with the
Warrant Agent a notice of the increase. The Company shall give the notice at
least 15 days before the date the increased Exercise Rate takes effect. The
notice shall state the increased Exercise Rate and the period it will be in
effect. A voluntary increase in the Exercise Rate shall not change or adjust
the Exercise Rate otherwise in effect as determined by this Section 13.

                  (k)      Multiple Adjustments. After an adjustment to the
                           --------------------
Exercise Rate for outstanding Warrants under this Section 13, any subsequent
event requiring an adjustment under this Section 13 shall cause an
adjustment to the Exercise Rate for outstanding Warrants as so adjusted.

                  (l)      When De Minimis Adjustment May Be Deferred. No
                           ------------------------------------------
adjustment in the Exercise Rate or Exercise Price shall be required unless
such adjustment would require an increase or decrease of at least 1% in such
rate or price; provided, however, that any adjustments which by reason of
               --------  -------
the foregoing are not required to be made shall be carried forward and taken
into account in any subsequent adjustment. All calculations shall be made by
the Company and shall be rounded to the sixth decimal place. No adjustment
need be made for a change in the par value of the Common Stock and no
adjustment shall be deferred beyond the date on which a Warrant is
exercised.

                  (m)      Amendments of the Certificate of Incorporation.
                           ----------------------------------------------
The Company shall not amend its Certificate of Incorporation in a manner
that adversely affects the holders of Warrants, without the prior consent of
the holders of a majority of the Warrants outstanding (excluding Warrants
held by the Company or any of its Affiliates), as determined in good faith
by the Company's board of directors.

                  SECTION 14. Fractional Interests. The Company shall not be
                              --------------------
required to issue fractional Warrant Shares on the exercise of Warrants. If
more than one Warrant shall be presented for exercise in full at the same
time by the same holder, the number of full Warrant Shares which shall be
issuable upon the exercise thereof shall be computed on the basis of the
aggregate number of Warrant Shares purchasable on exercise of the Warrants
so presented. If any fraction of a Warrant Share would, except for the
provisions of this Section 14, be issuable on the exercise of any Warrants
(or specified portion thereof), the Company shall pay an amount in cash
equal to the Current Market Value per Warrant Share on the day immediately
preceding the date the Warrant is presented for exercise, multiplied by such

                  Any notice or communication to a holder shall be mailed by
first class mail, postage prepaid, to its address shown on the register kept

                  SECTION 17. Supplements and Amendments. (a) From time to
                              --------------------------
time, the Company and the Warrant Agent, without the consent of the Holders
of the Warrants, may amend or supplement this Agreement for certain
purposes, including curing ambiguities, defects or inconsistencies or making
any change that does not adversely affect the legal rights of any Holder.
Any amendment or supplement to this Agreement that adversely affects the
legal rights of the Holder of the Warrants will require the written consent
of the Holders of a majority of the then outstanding Warrants (excluding
Warrants held by the Company or any of its Affiliates). The consent of each
Holder of the Warrants affected will be required for any amendment pursuant
to which the Exercise Price would be increased or the number of Warrant
Shares purchasable upon exercise of Warrants would be decreased (other than
pursuant to adjustments provided in this Agreement) or any of the adjustment
provisions in this Agreement would be changed in a manner that would have
any such effect.

                  (b) After an amendment or modification under this
Section 17 becomes effective, the Company shall mail to the Holders affected
thereby a notice briefly describing such amendment or



<PAGE>
<PAGE>

                                    -24-


modification. 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 or modification.

                  In connection with any amendment or modification under
this Section 17, the Company may offer, but shall not be obligated to offer,
to any Holder who consents to such amendment or modification, consideration
for such Holder's consent, so long as such consideration is offered to all
Holders.

                  (c) Executed or true and correct copies of any amendment
or modification effected pursuant to the provisions of this Section 17 shall
be delivered by the Company to each Holder of outstanding Warrants or
Warrant Shares forthwith following the date on which the same shall have
been executed and delivered by the Holder or Holders of the requisite
percentage of outstanding Warrant Shares (but only to the extent the Company
has been provided with the addresses for the Holders).

                  (d) Notwithstanding anything contained in this Agreement
to the contrary, the Warrant Agent may, but shall not be obligated to, enter
into any supplement or amendment that affects the Warrant Agent's own
rights, duties, obligations or immunities under this Agreement.

                  SECTION 18. Concerning the Warrant Agent. The Warrant
                              ----------------------------
Agent undertakes the duties and obligations expressly imposed by this
Agreement (and no implied duties) upon the following terms and conditions,
by all of which the Company and the Holders, by their acceptance of
Warrants, shall be bound:

                  (a)      The statements contained herein and in the Warrant
         Certificate shall be taken as statements of the Company, and the
         Warrant Agent assumes no responsibility for the correctness of any
         of the same except such as describe the Warrant Agent or any action
         taken by it. The Warrant Agent assumes no responsibility with
         respect to the distribution of the Warrants except as herein
         otherwise provided.

                  (b)      The Warrant Agent shall be protected and shall not
         be responsible for and shall incur no liability to the Company or any
         Holder for any failure of the Company to comply with the covenants
         contained in this Agreement or in the Warrants to be complied with
         by the Company.

                  (c)      The Warrant Agent may execute and exercise any of the
         rights or powers hereby vested in it or perform any duty hereunder
         either itself (through its employees) or by or through its
         attorneys or agents (which shall not include its employees) and
         shall not be responsible for the misconduct of any attorney or
         agent appointed by it without gross negligence or willful
         misconduct.

                  (d)      The Warrant Agent may consult at any time with legal
         counsel satisfactory to it (who may be counsel for the Company or
         an employee of the Warrant Agent), and the Warrant Agent shall
         incur no liability or responsibility to the Company or to any
         Holder in respect of any action taken, suffered or omitted by it
         hereunder in accordance with the opinion or the advice of such
         counsel.

                                    -25-


                  (e)      Whenever in the performance of its duties under this
         Agreement the Warrant Agent shall deem it necessary or desirable
         that any fact or matter be proved or established by the Company
         prior to taking or suffering any action hereunder, such fact or
         matter (unless such evidence in respect thereof be herein
         specifically prescribed) may be deemed conclusively to be proved
         and established by a certificate signed by the Chairman of the
         Board, the President, one of the Vice Presidents, the Treasurer or
         the Secretary of the Company and delivered to the Warrant Agent;
         and such certificate shall be full authorization to the Warrant
         Agent for any action taken or suffered by it under the provisions
         of this Agreement in reliance upon such certificate.

                  (f)      The Company agrees to pay the Warrant Agent such
         compensation for all services rendered by the Warrant Agent in the
         performance of its duties under this Agreement as may be separately
         agreed in writing, to reimburse the Warrant Agent for all expenses,
         taxes and governmental charges and other charges of any kind and
         nature incurred by the Warrant Agent in the performance of its
         duties under this Agreement (including, without limitation,
         reasonable fees and expenses of counsel), and to indemnify the
         Warrant Agent and its agents, employees, directors, officers and
         affiliates and save it and them harmless against any and all
         liabilities, losses and expenses, including, without limitation,
         judgments, costs and counsel fees, for anything done or omitted by
         the Warrant Agent in the acceptance and performance of its duties
         under this Agreement, except as a result of the Warrant Agent's
         gross negligence or bad faith, including, without limitation, the
         costs and expenses of defending against any claim (whether asserted
         by the Company, a Holder or any other Person) of liability in the
         premises including reasonable attorneys' fees and expenses. The
         provisions of this paragraph shall survive the resignation or
         removal of the Warrant Agent and the termination of this Agreement.

                  (g)      The Warrant Agent shall be under no obligation to
         institute any action, suit or legal proceeding or to take any other
         action likely to involve expense unless the Company or one or more
         holders shall furnish the Warrant Agent with reasonable security
         and indemnity for any costs and expenses which may be incurred, but
         this provision shall not affect the power of the Warrant Agent to
         take such action as the Warrant Agent may consider proper, whether
         with or without any such security or indemnity. All rights of
         action under this Agreement or under any of the Warrants may be
         enforced by the Warrant Agent without the possession of any of the
         Warrants or the production thereof at any trial or other proceeding
         relative thereto, and any such action, suit or proceeding
         instituted by the Warrant Agent shall be brought in its name as
         Warrant Agent, and any recovery of judgment shall be for the
         ratable benefit of the holders, as their respective rights or
         interests may appear.

                  (h)      The Warrant Agent and any stockholder, director,
         officer or employee ("Related Parties") of the Warrant Agent may
                               ---------------
         buy, sell or deal in any of the Warrants or other securities of the
         Company or become pecuniarily interested in any transactions in
         which the Company may be interested, or contract with or lend money
         to the Company or otherwise act as fully and freely as though it
         were not Warrant Agent under this Agreement or such director,
         officer or employee. Nothing herein shall preclude the Warrant
         Agent or any Related Party from acting in any other capacity for
         the Company or for any other legal entity including,



<PAGE>
<PAGE>

                                    -26-


         without limitation, acting as Transfer Agent or as a lender to the
         Company or an affiliate thereof.

                  (i)      The Warrant Agent shall act hereunder solely as
         agent, and its duties shall be determined solely by the provisions
         thereof. The Warrant Agent shall not be liable for anything which
         it may do or refrain from doing in connection with this Agreement
         except for its own gross negligence or bad faith. No implied duties
         or obligations shall be read into this Agreement against the
         Warrant Agent.

                  (j)      The Warrant Agent will be protected and will not
         incur any liability or responsibility to the Company or to any holder
         for any action taken, suffered or omitted by it in reliance on any
         notice, resolution, waiver, consent, order, certificate, or other
         paper, document or instrument reasonably believed by it to be
         genuine and to have been signed, sent or presented by the proper
         party or parties.

                  (k)      The Warrant Agent is hereby authorized and directed
         to accept instructions with respect to the performance of its duties
         hereunder from the Chairman of the Board, the President, Chief
         Financial Officer, Treasurer, any Vice President or the Secretary
         of the Company, and to apply to such officers for advice or
         instructions in connection with its duties, and shall not be liable
         for any action taken or suffered to be taken by it without gross
         negligence or bad faith in accordance with instructions of any such
         officer or officers.

                  (l)      By countersigning Warrant Certificates or by any
         other act hereunder the Warrant Agent shall not be deemed to make any
         representations as to validity or authorization of the Warrants or
         the Warrant Certificates (except as to its countersignature
         thereon) or of any securities or other property delivered upon
         exercise or tender of any Warrant, or as to the accuracy of the
         computation of the Exercise Price or the number or kind or amount
         of stock or other securities or other property deliverable upon
         exercise of any Warrant or the correctness of the representations
         of the Company made in any certifications that the Warrant Agent
         receives. The Warrant Agent shall not have any duty to calculate or
         determine any adjustments with respect either to the Exercise Price
         or the kind and amount of shares or other securities or any
         property receivable by holders of Warrants upon the exercise or
         tender of Warrants required from time to time, and the Warrant
         Agent shall have no duty or responsibility in determining the
         accuracy or correctness of any such calculation.

                  (m)      No provision of this Agreement shall require the
         Warrant Agent to expend or risk its own funds or otherwise incur
         any financial liability in the performance of any of its duties
         hereunder or in the exercise of its rights if there shall be
         reasonable grounds for believing that repayment of such funds or
         adequate indemnification against such risk or liability is not
         reasonably assured to it.

                  SECTION 19. Change of Warrant Agent. The Warrant Agent may
                              -----------------------
resign and be discharged from its duties under this Agreement by giving to
the Company 30 days' notice in writing. The Warrant Agent may be removed by
like notice to the Warrant Agent from the Company. If the Warrant Agent
shall resign or be removed or shall otherwise become incapable of acting,
the



<PAGE>
<PAGE>

                                    -27-


Company shall appoint a successor to the Warrant Agent. If the Company
shall fail to make such appointment within a period of 30 days after such
removal or after it has been notified in writing of such resignation or
incapacity by the resigning or incapacitated Warrant Agent or by any holder
(who shall with such notice submit his Warrant for inspection by the
Company), then any holder or the resigning or removed Warrant Agent may
apply to any court of competent jurisdiction for the appointment of a
successor to the Warrant Agent. Pending appointment of a successor to the
Warrant Agent, either by the Company or by such court, the duties of the
Warrant Agent shall be carried out by the Company. Any successor warrant
agent, whether appointed by the Company or such a court, shall be a bank or
trust company in good standing, incorporated under the laws of the United
States of America or any State thereof or the District of Columbia and
having at the time of its appointment as warrant agent a combined capital
and surplus of at least $50,000,000. After appointment, the successor
warrant agent shall be vested with the same powers, rights, duties and
responsibilities as if it had been originally named as Warrant Agent without
further act or deed; but the former Warrant Agent shall deliver and transfer
to the successor warrant agent any property at the time held by it
hereunder, and execute and deliver any further assurance, conveyance, act or
deed necessary for such purpose. Failure to file any notice provided for in
this Section 19, however, or any defect therein, shall not affect the
legality or validity of the resignation or removal of the Warrant Agent or
the appointment of the successor warrant agent, as the case may be. In the
event of such resignation or removal, the Company or the successor warrant
agent shall mail by first class mail, postage prepaid, to each Holder,
written notice of such removal or resignation and the name and address of
such successor warrant agent.

                  SECTION 20. Identity of Transfer Agent. Forthwith, the
                              --------------------------
Transfer Agent for the Common Stock, or any other shares of the Company's
Capital Stock issuable upon the exercise of the Warrants shall be Equiserve
Trust Company, N.A.

                  SECTION 21. SEC Reports and Other Information. Whether or
                              ---------------------------------
not the Company and the Subsidiary Guarantors (as defined in the Indenture)
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 Warrants 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 to file such
documents if the Company and the Subsidiary Guarantors were so subject,
unless, in any case, such files 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 Warrant Agent
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 Warrants
remain outstanding, furnish to the Holders of the Warrants 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 22. Successors. All the covenants and provisions
                              ----------
of this Agreement by or for the benefit of the Company, the Warrant Agent or
any holder of Warrants shall bind and inure to the benefit of their
respective successors and assigns hereunder.

                  SECTION 23. Termination. This Agreement shall terminate on
                              -----------
the Expiration Date. Notwithstanding the foregoing, this Agreement will
terminate on any earlier date if all Warrants have been exercised or
redeemed pursuant to this Agreement or the Company's Certificate of
Incorporation.

                  SECTION 24. Governing Law. This Agreement and each Warrant
                              -------------
Certificate issued hereunder shall be deemed to be a contract made under the
laws of the State of New York and shall be governed by and construed in
accordance with the laws of said State, without regard to the conflict of
law rules thereof.

                  SECTION 25. Benefits of This Agreement. Nothing in this
                              --------------------------
Agreement shall be construed to give to any person or corporation other than
the Company, the Warrant Agent and the registered holders of the Warrant
Certificates from time to time any legal or equitable right, remedy or claim
under this Agreement; but this Agreement shall be for the sole and exclusive
benefit of the Company, the Warrant Agent and the registered holders of the
Warrant Certificates.

                  SECTION 26. Counterparts. This Agreement may be executed
                              ------------
in any number of counterparts and each of such counterparts shall for all
purposes be deemed to be an original, and all such counterparts shall
together constitute but one and the same instrument.

                                   FORM OF

                        COMMON STOCK PURCHASE WARRANT
                                     OF
                                SOLUTIA INC.


                  THIS CERTIFIES THAT [          ], or its registered assigns,
is the registered holder of                Warrants (the "Warrants"). Each
                            --------------                --------
Warrant entitles the holder thereof (the "Holder"), at its option at any
                                          ------
time on or after the Separation Date and subject to the provisions contained
herein and in the Warrant Agreement referred to below, to purchase from
Solutia Inc., a Delaware corporation (the "Company"), 24.814 shares of
                                           -------
Common Stock, par value $0.01 per share, of the Company at an exercise price
per share equal to $7.59 (the "Exercise Price").
                               --------------

                  This Warrant Certificate shall terminate and become void
as of the close of business on the earlier of (1) the Deadline if the
Solutia Assumption does not occur on or before such date or (2) July 15,
2009 (the "Expiration Date") or, if earlier, upon the exercise hereof as to
           ---------------
all the shares of Common Stock subject hereto. The number of shares issuable
upon exercise of the Warrants shall be subject to adjustment from time to
time as set forth in the Warrant Agreement (as defined).

                  This Warrant Certificate is issued under and in accordance
with a Warrant Agreement dated as of July 9, 2002 (the "Warrant Agreement"),
                                                        -----------------
between the Company and HSBC Bank USA as Warrant Agent, and is subject to
the terms and provisions contained in the Warrant Agreement, to all of which
terms and provisions the Holder of this Warrant Certificate consents by
acceptance hereof. The Warrant Agreement is hereby incorporated herein by
reference and made a part hereof. Reference is hereby made to the Warrant
Agreement for a full statement of the respective rights, limitations of
rights, duties and obligations of the Company and the Warrantholders.
Capitalized terms used but not defined herein shall have the meanings
ascribed thereto in the Warrant Agreement. A copy of the Warrant Agreement
may be obtained for inspection by the Holder hereof upon written request to
the Company at Solutia Inc., 575 Maryville Center Drive, P.O. Box 66760,
St. Louis, MO 63166-6760, Attn: General Counsel.

                  Subject to the terms of the Warrant Agreement, the
Warrants may be exercised upon surrender at the office or agency of the
Company maintained for such purpose, which initially will be the issuer
services office of the Warrant Agent in New York, New York, of the
certificate or certificates evidencing the Warrants to be exercised with the
form of election to purchase on the reverse thereof duly filled in and
signed, and upon payment to the Warrant Agent for the account of the Company
of the Exercise Price for the number of Warrant Shares in respect of which
such Warrants are then exercised. The Exercise Price may be paid at the
holder's election (i) in cash in United States dollars by wire transfer or
by certified or official bank check to the order of the Company or (ii) by
the surrender of one or more Warrant Certificates (and without the payment
of the Exercise Price in cash) in exchange for a number of shares of the
Company's Common Stock equal to the product of (a) the number of shares of
the Company's Common Stock for which such Warrant is exercisable as of


                                    A-2


<PAGE>
<PAGE>

the Exercise Date (if the Exercise Price were being paid in cash), and (b) the
Cashless Exercise Ratio. The "Cashless Exercise Ratio" shall equal a
fraction, the numerator of which is the excess of the Current Market Value
per share of the Company's Common Stock on the Exercise Date over the
Exercise Price per share as of the Exercise Date and the denominator of
which is the Current Market Value per share of the Company's Common Stock on
the Exercise Date. Upon surrender of a Warrant Certificate representing more
than one Warrant, the number of shares of the Company's Common Stock
deliverable upon a Cashless Exercise shall be equal to the product of the
number of shares of the Company's Common Stock issuable in respect of those
Warrants that the holder specifies are to be exercised pursuant to a
Cashless Exercise multiplied by the Cashless Exercise Ratio. All provisions
of the Warrant Agreement shall be applicable with respect to an exercise of
a Warrant Certificate pursuant to a Cashless Exercise for less than the full
number of Warrants represented thereby.

                  The Warrants shall be exercisable only in whole. In the
event that a certificate evidencing Warrants is exercised in respect of
fewer than all of the Warrants evidenced thereby at any time prior to the
date of expiration of the Warrants, a new certificate evidencing the
remaining Warrant or Warrants will be issued, and the Warrant Agent is
irrevocably authorized to countersign and to deliver the required new
Warrant Certificate or Certificates pursuant to the Warrant Agreement, and
the Company, whenever required by the Warrant Agent, will promptly supply
the Warrant Agent with Warrant Certificates duly executed on behalf of the
Company for such purpose.

                  This Warrant Certificate shall not be valid unless
countersigned by the Warrant Agent as such term is used in the Warrant
Agreement.

                  As provided in the Warrant Agreement, the Exercise Rate
and the Exercise Price are subject to adjustment upon the happening of
certain events.

                  The Company will pay all documentary stamp taxes
attributable to the initial issuance of Warrant Shares upon the exercise of
Warrants; provided, however, that the Company shall not be required to pay
          --------  -------
any tax or taxes which may be payable in respect of any transfer involved in
the issue of any Warrant Certificates or any certificates for Warrant Shares
in a name other than that of the registered holder of a Warrant Certificate
surrendered upon the exercise of a Warrant, and the Company shall not be
required to issue or deliver such Warrant Certificates unless or until the
person or persons requesting the issuance thereof shall have paid to the
Company the amount of such tax or shall have established to the satisfaction
of the Company that such tax has been paid.

                  The Company shall not be required to issue fractional
Warrant Shares on the exercise of Warrants. If more than one Warrant shall
be presented for exercise in full at the same time by the same holder, the
number of full Warrant Shares which shall be issuable upon the exercise
thereof shall be computed on the basis of the aggregate number of Warrant
Shares purchasable on exercise of the Warrants so presented. If any fraction
of a Warrant Share would be issuable on the exercise of any Warrants (or
specified portion thereof), the Company shall pay an amount in cash equal to
the Current Market Value per Warrant Share on the day immediately preceding
the date the Warrant is presented for exercise, multiplied by such fraction.

                  All Warrant Shares issuable by the Company upon the
exercise of the Warrants shall, upon such issue, be duly and validly issued
and fully paid and non-assessable.

                  The Company and the Warrant Agent may deem and treat
Holders of the Warrant Certificates as the absolute owners thereof
(notwithstanding any notation of ownership or other writing thereon made by
anyone) for all purposes, and neither the Company nor the Warrant Agent
shall be affected by any notice to the contrary.

Ladies and Gentlemen:

                  In connection with our proposed purchase of warrants to
purchase Common Stock, par value $0.01 per share (the "Securities"), of
                                                       ----------
Solutia Inc. (the "Company"), we confirm that:
                   -------

                  1. We understand that the Securities have not been
         registered under the Securities Act of 1933, as amended (the
         "Securities Act"), and, unless so registered, may not be offered,
          --------------
         sold or otherwise transferred except as permitted in the following
         sentence. We agree on our own behalf and on behalf of any investor
         account for which we are purchasing Securities to offer, sell or
         otherwise transfer such Securities prior to the date which is two
         years after the later of the date of original issue and the last
         date on which the Company or any affiliate of the Company was the
         owner of such Securities (or any predecessor Securities) (the
         "Resale Restriction Termination Date") only (a) to the Company,
          -----------------------------------
         (b) pursuant to a registration statement which has been declared
         effective under the Securities Act, (c) for so long as the
         Securities are eligible for resale pursuant to Rule 144A under the
         Securities Act, to a person we reasonably believe is a qualified
         institutional buyer as defined in Rule 144A (a "QIB") that
                                                         ---
         purchases for its own account or for the account of a QIB and to
         whom notice is given that the transfer is being made in reliance on
         Rule 144A, (d) pursuant to offers and sales that occur outside the
         United States within the meaning of Regulation S under the
         Securities Act, (e) to an institutional "accredited investor"
         within the meaning of subparagraph (a)(1), (a)(2), (a)(3) or (a)(7)
         of Rule 501 under the Securities Act that is acquiring the
         Securities for its own account or for the account of such an
         institutional "accredited investor", for investment purposes and
         not with a view to, or for offer or sale in connection with, any

         institutional "accredited investor" within the meaning of subparagraph
         (a)(1), (a)(2), (a)(3) or (a)(7) of Rule 501 under the Securities
         Act and that it is acquiring such Securities for investment purposes
         and not for distribution in violation of the Securities Act. The
         Warrant Agent and the Company reserve the right prior to any offer,
         sale or other transfer prior to the Resale Restriction Termination
         Date of the Securities pursuant to clause (c), (d), (e) or (f) above
         to require the delivery of a written opinion of counsel,

                  2. We are an institutional "accredited investor" (as
         defined in Rule 501(a)(1), (a)(2), (a)(3) or (a)(7) of Regulation D
         under the Securities Act) purchasing for our own account or for the
         account of such an institutional "accredited investor", and we are
         acquiring the Securities for investment purposes and not with a
         view to, or for offer or sale in connection with, any distribution
         in violation of the Securities Act and we have such knowledge and
         experience in financial and business matters as to be capable of
         evaluating the merits and risks of our investment in the
         Securities, and we and any accounts for which we are acting are
         each able to bear the economic risk of our or its investment for an
         indefinite period.

                  3. We are acquiring the Securities purchased by us for our
         own account or for one or more accounts as to each of which we
         exercise sole investment discretion.
