           4.7    Redetermination Amounts. Except as otherwise provided in
Sections 9, 10, 11 and 12 of this Agreement, for any Pre-Deconsolidation Period,
in the event of a redetermination of any Tax Item of any member of a

Periods for which Subsidiary has filing responsibility, including under this
Agreement.

           4.9    Special Rules For Allocating Taxes.  (a) Closing of Tax Years.
For U.S. federal Income Tax purposes, the taxable year of the Subsidiary Group
shall end as of the close of the Deconsolidation Date with respect to Subsidiary
and, with respect to all other Income Taxes, FMC (or the appropriate member of
the FMC Group) and Subsidiary (or the appropriate member of the Subsidiary
Group) shall, unless prohibited by applicable law, take all action necessary or
appropriate to close the taxable period of the members of the Subsidiary Group
as of the close of such Deconsolidation Date.  Neither any member of the FMC
Group nor any member of the  Subsidiary Group shall take any position
inconsistent with the preceding sentence on any Income Tax Return.  If a Person
is permitted but not required under applicable state, local or foreign income
tax laws to treat the Deconsolidation Date as the last day of a taxable period,
then the parties shall cause such Person to treat that day as the last day of a
taxable period.

                  (b)  Partnership and Flowthrough Entities. In the case of any
Income Tax Liability of any member of the FMC Group or the Subsidiary Group
which is attributable to the ownership by such member of an equity interest in a
partnership or other "flowthrough" entity for Income Tax purposes, such
allocation shall be made as if the taxable period of such partnership or other
"flowthrough" entity ended as of the close of the Deconsolidation Date; provided
that to the extent that the information necessary to compute such allocation on
the basis of an interim closing of the books of such "flowthrough" entity is not
available to FMC or Subsidiary, such allocation shall be made between the period
ending on the Deconsolidation Date and the period after the Distribution Date in
proportion to the number of days in each such period.

           4.10   Separate Agreements. Notwithstanding any other provision of
this Agreement, in the event that there is a conflict between the provisions of
this Agreement governing the payment or allocation of Taxes and any separate
written agreement entered into in connection with the Restructuring (including
the Separation Agreement) regarding the payment or allocation of Taxes, such
separate agreement shall control.

     Section 5.   Tax Attributes
                  --------------

           5.1    Allocation of Tax Items. (a) In General. All Tax computations

Affiliate and (iii) any Straddle Period, shall be made pursuant to the
principles of Section 1.1502-76(b) of the Treasury Regulations or of a
corresponding provision under the laws of other jurisdictions and, to the extent
possible, in a manner consistent with the principles set forth in Section 4.2(a)
of this Agreement.

                  (b)  Reattribution. In the event of a Deconsolidation, FMC

If FMC makes such election, Subsidiary shall comply with the requirements of
Section 1.1502-20(g)(5) of the Treasury Regulations.

provide on reasonable demand books, records, documentation or other information

which FMC owns a Fifty Percent or Greater Interest in the outstanding stock of

<PAGE>

any Tax information as to which any member of the Subsidiary Group is entitled
to assert the protection of any Privilege or (2) any Tax information as to which
any member of the Subsidiary Group is subject to an obligation to maintain the
confidentiality of such information. Subsidiary shall use reasonable efforts to
separate any such information from any other information to which FMC is

the extent consistent with preserving its rights under this Section 6.1(d).

                  (e)  FMC agrees to notify Subsidiary in writing within ten

                  (f)  Notwithstanding any other provision of this Agreement,
all books, records, documentation or other information relating to Taxes for any
period (or portion thereof) ending on or before the Deconsolidation Date of (i)
FMC or any FMC Affiliate and (ii) Subsidiary or any Subsidiary Affiliate shall
be the property of, and shall be retained by, FMC; provided, however, that
                                                   --------  -------
Subsidiary shall be permitted, at its own expense, to obtain copies of any
books, records, documentation or other information relating to any Pre-
Deconsolidation Period Tax Return of Subsidiary or any Subsidiary Affiliate
other than any books, records, documentation or other information described in

           6.2    Indemnification. (a) Failure to Pay. FMC and each FMC
Affiliate shall jointly and severally indemnify Subsidiary, each Subsidiary
Affiliate and each of their respective Representatives, and hold them harmless
from and against any Tax or Losses that are attributable to, or results from the
failure of FMC or any FMC Affiliate to make any payment required to be made
under this Agreement. Subsidiary and each Subsidiary Affiliate shall jointly and
severally indemnify FMC, each FMC Affiliate and each of their respective
Representatives, and hold them harmless from and against any Tax or Losses that

Subsidiary Affiliate to make any payment required to be made under this
Agreement.

                  (b)  Inaccurate or Incomplete Information.  FMC and each FMC

           6.3    Tax Consequences of Payments. (a) Tax Characterization of
Payments. For all Tax purposes and notwithstanding any other provision of this
Agreement, to the extent permitted by applicable law, the parties hereto shall
treat any payment made pursuant to this Agreement (other than any payment made
in satisfaction of an intercompany obligation) as a capital contribution or
dividend distribution, as the case may be, immediately prior to the IPO Date
and, accordingly, as not includible in the taxable income of the recipient. If,
as a result of a Final Determination, it is determined that the receipt or
accrual of any payment made under this

                                      -21-
<PAGE>

Agreement is taxable to the Indemnified Party, the Indemnifying Party of this
Agreement shall pay to the Indemnified Party an amount equal to any increase in
the Income Taxes of the Indemnified Party as a result of receiving the payment
from the Indemnifying Party (grossed up to take into account such payment, if
applicable).

                  (b)  Adjustments to Payments.  Any Indemnified Party that has
received a payment under this Agreement from an Indemnifying Party with respect
to any Losses or Taxes suffered or incurred by the Indemnified Party ( an
"Indemnified Loss") shall pay to such Indemnifying Party an amount equal to any
"Tax Saving Amount" Actually Utilized by the Indemnified Party promptly after it
is Actually Realized, but only if and to the extent that such Tax Saving Amount
is Actually Realized within five (5) years of the date hereof.  For purposes of
this Section 6.3(b), the Tax Saving Amount shall equal the amount by which the
Income Taxes of the Indemnified Party or any of its affiliates are reduced
(including, without limitation, through the receipt of a Refund, credit or
otherwise), plus any related interest received from a Tax Authority, as a result
of claiming as a deduction or offset on any relevant Tax Return amounts
attributable to an Indemnified Loss (the "Indemnifiable Loss Deduction").

                  (c)  Reporting of Indemnifiable Loss.  In the event that an
Indemnified Party incurs an Indemnified Loss, such Indemnified Party shall claim
as a deduction or offset on any relevant Tax Return (including, without
limitation, any claim for Refund) such Indemnified Loss to the extent such
position is supported by "substantial authority" (within the meaning of Section
1.6662-4(d) of the Treasury Regulations) with respect to United States federal,
state and local Tax Returns or has similar appropriate authoritative support
with respect to any Tax Return other than United States federal, state and local
Tax Returns.  The Indemnified Party shall have primary responsibility for the
preparation of its Tax Returns and reporting thereon such Indemnifiable Loss
Deduction; provided, that the Indemnified Party shall consult with, and provide
the Indemnifying Party with a reasonable opportunity to review and comment on
the portion of the Indemnified Party's Tax Return relating to the Indemnified
Loss.  If a dispute arises between the Indemnified Party and the Indemnifying
Party as to whether there is "substantial authority" (with respect to United
States federal, state and local Tax Returns) or similar appropriate
authoritative support (with respect to any Tax Return other than United States
federal, state and local Tax Returns) for the claiming of an Indemnifiable Loss
Deduction, such dispute shall be resolved in accordance with the principles and
procedures set forth in Section 8 of this Agreement.  Both FMC and Subsidiary
shall (and shall cause its respective affiliates to) act in good faith to
coordinate their Tax Return filing positions with respect to the taxable periods
that include an Indemnifiable Loss Deduction.  There shall be an adjustment to
any Tax Saving Amount calculated under Section 6.3(b) hereof in the event of any
Proceeding which results in a Final Determination that increases or decreases
the amount of the Indemnifiable Loss Deduction reported on any relevant Tax
Return of the Indemnified Party.  The Indemnified Party shall promptly inform
the Indemnifying Party of any such Proceeding and shall attempt in good faith to
sustain the Indemnifiable Loss Deduction at issue in the Proceeding.  If a
written notice of a Final Determination in respect of an Indemnifiable Loss
Deduction is received within five (5) years of the date hereof, the Indemnified
Party shall redetermine the Tax Saving Amount attributable to the Indemnifiable
Loss Deduction under Section 6.3(b) hereof, taking into account the Final
Determination (the "Restated Tax Saving Amount").  If the Restated Tax Saving
Amount is greater than the Tax Saving Amount, the Indemnified Party shall
promptly pay the Indemnifying Party an amount equal to the difference between
such amounts.  If the Restated

                                      -22-
<PAGE>

Tax Saving Amount is less than the Tax Saving Amount, then the Indemnifying
Party shall promptly pay the Indemnified Party an amount equal to the difference
between such amounts.

           6.4    Interest. Unless a different rate of interest is provided for
in this Agreement, payments pursuant to this Agreement that are not made within
the period prescribed in this Agreement or, if no period is prescribed, within
fifteen (15) Business Days after demand for payment is made (the "Payment
Period") shall bear interest for the period from and including the date
immediately following the last date of the Payment Period through and including
the date of payment at a per annum rate equal the Prime Rate. Such interest will
be payable at the same time as the payment to which it relates and shall be
calculated based on a year of 365 or 366 days, as appropriate, for the actual
number of days for which due.

           6.5    Stock Options and Restricted Stock

                  (a)  In General. Notwithstanding any contrary provision
contained herein, the parties hereto agree that FMC shall be entitled to any Tax
Benefit arising by reason of exercises of Options to purchase shares of FMC
stock, and that Subsidiary shall be entitled to any Tax Benefit arising by
reason of exercises of options to purchase shares of Subsidiary stock. In
addition, FMC shall be entitled to any Tax Benefit arising by reason of the
lapse of any restrictions with respect to shares of FMC stock, Subsidiary stock
or other property subject to a substantial risk of forfeiture (within the
meaning of Section 83 of the Code) held by an employee of FMC, and Subsidiary
shall be entitled to any Tax Benefit arising by reason of the lapse of any
restrictions with respect to shares of Subsidiary stock, FMC stock or other
property subject to a substantial risk of forfeiture (within the meaning of
Section 83 of the Code) held by an employee of Subsidiary. The parties hereto
agree to report all Tax deductions with respect to stock options and other
equity issued to their employees consistently with this Section 6.5(a), to the
extent permitted by law.

                  (b)  Notices, Withholding, Reporting. FMC shall promptly
notify Subsidiary of any event giving rise to income to any Subsidiary Group
employees or former employees in connection with exercises of options to
purchase shares of FMC stock, or the lapse of any restrictions with respect to
shares of FMC stock or other property subject to a substantial risk of
forfeiture (within the meaning of Section 83 of the Code). If required by law,
Subsidiary shall withhold applicable Taxes and satisfy applicable Tax reporting
obligations in connection therewith.

                  (c)  Adjustments. If Subsidiary or any Subsidiary Affiliate
receives any Tax Benefit to which FMC is entitled under Section 6.5(a) of this
Agreement, Subsidiary shall pay the amount of such Tax Benefit to FMC. If FMC or
any FMC Affiliate receives any Tax Benefit to which Subsidiary is entitled under
Section 6.5(a) of this Agreement, FMC shall pay the amount of such Tax Benefit
to Subsidiary.

Item of a member of the Subsidiary Group, FMC shall promptly provide a copy of
such notice to Subsidiary (but in no event later than ten (10) Business Days
following the receipt of such notice). If Subsidiary or any member of the
Subsidiary Group receives written notice of, or relating to, any Proceeding from
a Tax Authority with respect to a Tax Return described in Section 2.l(a) of this
Agreement, Subsidiary shall promptly provide a copy of such notice to FMC (but
in no event later than ten (10) Business Days following the receipt of such
notice).

           7.3    Failure to Notify.  The failure of FMC or Subsidiary to notify
the other of any matter relating to a particular Tax for a taxable period or to
take any action specified in this Agreement shall not relieve such other party
of any liability and/or obligation which it may have under this Agreement with
respect to such Tax for such taxable period except to the extent that such other
party's rights hereunder are materially prejudiced by such failure.

           7.4    Remedies.  Subsidiary agrees that no claim against FMC and no
defense to Subsidiary's liabilities to FMC under this Agreement shall arise from
the resolution by FMC of any deficiency, claim or adjustment relating to the
redetermination of any Tax Item of FMC or a FMC Affiliate.

           7.5    Timing Differences.  Except as otherwise provided under this
Agreement, if, pursuant to a Final Determination, a party to this Agreement
suffers a Tax Detriment and, as a result, the other party to this Agreement
obtains a corresponding Tax Benefit, and such Tax Detriment is not otherwise
compensated under this Agreement, then the party obtaining such Tax Benefit
shall make a payment to the other party in an amount equal to such Tax Benefit,
but only to the extent such Tax Benefit is Actually Realized within five (5)
years of such Final Determination.

           7.6    Carrybacks. Except to the extent otherwise consented to by FMC
or prohibited by applicable law, Subsidiary shall elect to relinquish, waive or
otherwise forgo all Carrybacks. In the event that Subsidiary (or the appropriate
member of the Subsidiary Group) is prohibited by applicable law to relinquish,
waive or otherwise forgo a Carryback (or FMC consents thereto), (i) FMC shall
cooperate with Subsidiary, at Subsidiary's expense, in seeking from the
appropriate Tax Authority such Refund as reasonably would result from such
Carryback, and (ii) Subsidiary shall be entitled to any Tax Benefit Actually
Realized by a member of the FMC Group (including any interest thereon received
from such Tax Authority) within five (5) years of the date of such Carryback, to
the extent that (x) such Tax Benefit is directly attributable to such Carryback
and (y) such Tax Benefit would not have been Actually Utilized but for such
Carryback, within seven (7) Business Days after such Tax Benefit is Actually
Realized; provided, however, that Subsidiary shall indemnify and hold the
          --------  -------
members of the FMC Group harmless from and against any and all collateral tax
consequences resulting from or caused by any such Carryback, including (but not
limited to) the loss or postponement of benefit from the use of Tax Attributes
generated by a member of the FMC Group or an Affiliate thereof and (x) that
expire unutilized, but would have been utilized but for such Carryback, or (y)
the use of which is postponed to a later taxable period than the taxable period
in which such Tax Attributes otherwise would have been utilized but for such
Carryback.  If there is a Final Determination that results in any change to or
adjustment of a Tax Benefit Actually Utilized by a member of the FMC Group that
is directly attributable to a Carryback, then FMC (or its designee) shall make a
payment to Subsidiary, or Subsidiary shall make a payment to FMC (or its
designee), as may be necessary to

                                      -25-
<PAGE>

adjust the payments between Subsidiary and FMC (or its designee) to reflect the
payments that would have been made under this Section 7.6 had the adjusted
amount of such Tax Benefit been taken into account in computing the payments due
under this Section 7.6. For the avoidance of doubt, in the event that FMC or any
FMC Affiliate, on the one hand, and Subsidiary or any Subsidiary Affiliate, on
the other hand, both have Carrybacks applicable to the same period, the
determination of the Tax Benefit attributable to the Carryback of Subsidiary or
any Subsidiary Affiliate will be made after first giving effect to the Carryback
of FMC or any FMC Affiliate.

     Section 8.   Dispute Resolution.  In the event that FMC or any FMC
                  ------------------
Affiliate, as the case may be, on the one hand, and Subsidiary or any Subsidiary
Affiliate, as the case may be, on the other hand, disagree as to the amount or
calculation of any payment to be made under this Agreement, or the
interpretation or application of any provision under this Agreement, the parties
shall attempt in good faith to resolve such dispute.  If such dispute is not
resolved within sixty (60) Business Days following the commencement of the
dispute, FMC and Subsidiary shall jointly retain a tax attorney that is a member
of a nationally recognized law firm or independent public accounting firm, which
firm is independent of both parties (the "Independent Entity"), to resolve the
dispute.  The Independent Entity shall act as an arbitrator to resolve all
points of disagreement and its decision shall be final and binding upon all
parties involved.  Following the decision of the Independent Entity, FMC, the
FMC Affiliates, Subsidiary and the Subsidiary Affiliates shall each take or
cause to be taken any action necessary to implement the decision of the
Independent Entity.  The fees and expenses relating to the Independent Entity
shall be borne equally by FMC and Subsidiary.

     Section 9.   IPO
                  ---

           9.1    IPO Related Items.  (a)  Liability for Restructuring Taxes,
Deconsolidation Taxes and Other Foreign Restructuring Taxes.  Notwithstanding
any other provision of this Agreement (other than Section 9.l(b) hereof) and
except as provided in any separate written agreement between the parties entered
into in connection with the Restructuring (including the Separation Agreement),
(i) FMC shall be responsible for the payment of, and shall indemnify and hold
Subsidiary harmless from and against, any Deconsolidation Taxes and (ii)
responsibility for the payment of any Restructuring Taxes or Other Foreign
Restructuring Taxes shall be allocated in the manner provided in the Separation
Agreement.

                  (b)  Liability for Undertaking Certain Actions.
Notwithstanding Section 9.1(a) of this Agreement, Subsidiary and each Subsidiary
Affiliate shall be jointly and severally responsible for, and shall indemnify
and hold FMC harmless from and against, any Restructuring Taxes that are
attributable to, or result from, (i) any action taken by Subsidiary or any
Subsidiary Affiliate that was prohibited by this Agreement or was not
contemplated by the parties in connection with the Restructuring (including,
without limitation, by taking any action not contemplated in connection with
obtaining the Ruling or a Supplemental Ruling, or any opinions, rulings,
agreements or written advice relating to foreign transfers) or (ii) the failure
by Subsidiary or any Subsidiary Affiliate to take any action that Subsidiary is
responsible for taking under this Agreement, the Separation Agreement or any
other agreement related to the Restructuring or the IPO (including, without
limitation, by failing to make an election or enter into a transaction
specifically required in connection with obtaining a ruling from any Tax
Authority). Each of the parties hereto agrees to act in good faith and without
negligence in connection with the

                                      -26-
<PAGE>

Tax reporting of and all other aspects related to the Tax consequences of the
Restructuring, any Deconsolidation and any Secondary Restructuring and shall be
responsible for any Taxes or Losses arising from any failure to act in good
faith or any negligent act or omission with respect thereto.

           9.2    Tax Reporting of IPO Related Items.  (a) Restructuring Taxes.
Any Tax Return (or portion thereof) that includes any Tax Item resulting from
the Restructuring shall be prepared and filed by the party responsible for
preparing (or causing to be prepared) and filing such Tax Return (under Sections
2.1 and 2.2 of this Agreement); provided that, notwithstanding any other
provision of this Agreement, if Subsidiary is the party responsible for
preparing any such Tax Return (or portion thereof) (each a "Subsidiary IPO Tax

Days following the IPO Date, a written list of those Subsidiary IPO Tax Returns
that Subsidiary reasonably believes could result in the imposition of a Tax
liability of more than $10,000 for which FMC will be responsible pursuant to
this Section 9.  Within twenty (20) Business Days following the receipt of such
list, FMC shall provide a written list to Subsidiary of those Subsidiary IPO Tax
Returns that FMC wishes to review.  Subsidiary shall provide any such Subsidiary
IPO Tax Returns (or portions thereof) to FMC (no later than forty-five (45)
Business Days (or such shorter period as agreed to by FMC) prior to the due date
for the filing of such Tax Return (taking into account applicable extensions)),
for FMC's review and approval, which approval, to the extent it relates to any
Tax Item resulting from, or arising out of, the Restructuring may be withheld by
FMC in its sole discretion and any such Tax Item shall be reported as determined
by FMC in its sole discretion (so long as such reporting position is supported
by "substantial authority" (within the meaning of Section 1.6662-4(d) of the
Treasury Regulations) with respect to United States federal, state and local Tax
Returns or has similar appropriate authoritative support with respect to any Tax
Return other than United States federal, state and local Tax Returns).  In the
event that the time periods provided in this Section 9.2(a) would not provide
FMC with a reasonable period of time within which to review any such Subsidiary
IPO Tax Return prior to the filing of such Tax Return, then the parties shall
cooperate in order that FMC may participate in the preparation of such Tax
Return and have the rights otherwise provided in this Section 9.2(a).

                  (b)  Deconsolidation Taxes and Other Foreign Restructuring
Taxes. Any Tax Return (or portion thereof) that includes any Tax Item relating
to any Deconsolidation (to the extent resulting in Deconsolidation Taxes) or
Secondary Restructuring (to the extent resulting in Other Foreign Restructuring
Taxes) shall be prepared and filed by the party responsible for preparing and
filing such Tax Return (under Sections 2.1 and 2.2 of this Agreement); provided
that, notwithstanding any other provision of this Agreement, if Subsidiary is
the party responsible for preparing (or causing to be prepared) any such Tax
Return (or portion thereof) (each a "Subsidiary Restructuring Tax Return"),
Subsidiary shall provide any such Subsidiary Restructuring Tax Return (or
portion thereof) to FMC (no later than forty-five (45) Business Days (or such
shorter period as agreed to by FMC) prior to the due date for the filing of such
Tax Return (taking into account applicable extensions)), for FMC's review and
approval, which approval, to the extent it relates to any Tax Item relating to
any Deconsolidation (to the extent resulting in Deconsolidation Taxes) or
Secondary Restructuring (to the extent resulting in Other Foreign Restructuring
Taxes), may be withheld by FMC in its sole discretion and any such Tax Item
shall be reported as determined by FMC in its sole discretion (so long as such
reporting position is supported by "substantial authority" (within the meaning
of Section 1.6662-4(d) of

                                      -27-
<PAGE>

the Treasury Regulations) with respect to United States federal, state and local
Tax Returns or has similar appropriate authoritative support with respect to any
Tax Return other than United States federal, state and local Tax Returns).

           9.3    Proceedings Relating to Restructuring. Notwithstanding any
other provision of this Agreement, FMC shall have the exclusive right, in its
sole discretion, to control, contest, and represent the interests of FMC, any
FMC Affiliate, Subsidiary or any Subsidiary Affiliate in any Proceeding with
respect to Tax Items related to the Restructuring, Deconsolidation (to the
extent resulting in Deconsolidation Taxes) or Secondary Restructuring (to the
extent resulting in Other Foreign Restructuring Taxes), and to resolve, settle
or agree to any deficiency, claim or adjustment proposed, asserted or assessed
in connection with or as a result of any such Proceeding. FMC's rights shall
extend to any matter pertaining to the management and control of any Proceeding,
including execution of waivers, choice of forum, scheduling of conferences and
the resolution of any Tax Item.

           9.4    Provision of Information and Mutual Cooperation. In addition
to the parties' respective obligations under Section 6.1 of this Agreement, FMC
and Subsidiary shall, and shall cause their respective Affiliates to cooperate
with respect to all aspects of the Restructuring including, without limitation,
by (1) furnishing to the other in a timely manner such information, documents
and other materials as the other may reasonably request for purposes of (i)
preparing any Tax Return that includes Tax Items relating to or arising from the
Restructuring and (ii) contesting or defending any Proceeding with respect to
Tax Items relating to or arising from the Restructuring and (2) make its
employees available to the other to provide explanations of documents and

     Subsidiary Affiliate to take any action, and Subsidiary will not fail to
     take any action or permit any Subsidiary Affiliate to fail to take any
     action, where such action or failure to act would be inconsistent with or
     cause to be untrue any material, information, covenant or representation in
     the Ruling Documents, Supplemental Ruling Documents, Ruling, Supplemental
     Ruling or this Agreement.

                  (ii)  Subsidiary shall not take any action (including any
     cessation, transfer or disposition of its active trade or business; payment
     of extraordinary dividends to shareholders; and acquisitions or issuances
     or stock) or permit any Subsidiary Affiliate to take any action (including
     any cessation, transfer or disposition if its active trade or business;

     issuances or stock), and Subsidiary will not fail to take any action or
     permit any Subsidiary Affili-

                                      -28-
<PAGE>

     ate to fail to take any action, where such action or failure to act would
     cause the Spin-Off or the Internal Distribution not to have Tax-Free
     Status.

                  (iii)  Until the first day after the Restriction Period, no
     member of the Subsidiary Group shall sell, agree to sell or otherwise issue
     or agree to issue to any Person, or redeem or otherwise acquire from any
     Person, any Equity Securities of any member of the Subsidiary Group;
     provided, however, that (A) the adoption by Subsidiary of a rights plan
     --------  -------
     shall not constitute a sale or issuance of such Equity Securities, (B)
     Subsidiary may repurchase Equity Securities to the extent that such
     repurchases meet the requirements of section 4.05(1)(b) of Revenue
     Procedure 96-30 and (C) Subsidiary may, subject to the terms and conditions
     contained in paragraph (vi) below, issue Equity Securities of Subsidiary.

                  (iv)   Until the first day after the Restriction Period, no
     member of the Subsidiary Group shall (A) solicit any Person to make a
     tender offer for, or otherwise acquire or sell, the Equity Securities of
     Subsidiary, (B) participate in or support any unsolicited tender offer for,
     or other acquisition, issuance or disposition of, the Equity Securities of
     Subsidiary or (C) approve or otherwise permit any proposed business
     combination or any transaction which, in the case of (A), (B) or (C),
     individually or in the aggregate, together with the transactions
     contemplated by this Agreement, the Distribution Agreement, any other
     agreements or the Ruling Documents, Supplemental Ruling Documents, Ruling,
     Supplemental Ruling, results in one or more Persons acquiring (other than
     in acquisitions not taken into account for purposes of Section 355(e))

     Subsidiary, it would cause the Spin-Off not to have Tax-Free Status and
     (ii) in the case of such Subsidiary Affiliate, it would cause the Internal
     Distribution not to have Tax-Free Status. In addition, no member of the
     Subsidiary Group shall at any time, whether before or subsequent to the
     expiration of the Restriction Period, engage in any action described in
     clauses (A), (B) or (C) of the preceding sentence if it is pursuant to an
     arrangement or agreement negotiated (in whole or in part) prior to the
     Spin-Off, even if at the time of the Spin-Off it is subject to various
     conditions, nor shall any member take any action, or fail or omit to take
     any action, that would cause Section 355(d) or (e) to apply to the Spin-Off
     or the Internal Distribution.

                  (v)    Any of the provisions of Section 10.1(a)(1) shall be
     waived with respect to any particular transaction or transactions if (A)
     FMC or Subsidiary has obtained a Supplemental Ruling from the Service in
     accordance with and under the terms and conditions contained in paragraph
     (vi)(a) below, (B) FMC has determined, in its sole and absolute discretion,
     that it could not reasonably be expected that such proposed transaction
     would have an adverse effect on the Tax-Free Status of the Internal
     Distribution and the Spin-Off, or (C) Subsidiary satisfies the terms and
     conditions contained in paragraph (vi)(b) below. Waiver with respect to one
     transaction or group of transactions shall not constitute a waiver with
     respect to any other transaction.

                  (vi)   Except as provided in paragraphs (i) and (ii) above,
     until the first day after the Restriction Period, unless FMC and Subsidiary
     agree otherwise, prior to entering into any agreement to (A) sell all or
     substantially all of the assets of Subsidiary

                                      -29-
<PAGE>

     or any Subsidiary Affiliate, (B) merge Subsidiary or any Subsidiary
     Affiliate with another entity (without regard to which party is the
     surviving entity) or (C) issue Equity Securities of Subsidiary or any
     Subsidiary Affiliate in an acquisition or public or private offering
     (excluding any issuance pursuant to the exercise of employee stock options
     or other employment related arrangements):

               a)  Subsidiary shall request that FMC obtain a Supplemental
          Ruling in accordance with Section 10.1(d)(1) of this Agreement that
          such transaction will not affect the treatment of the Spin-Off and the
          Internal Distribution under Section 355 of the Code and FMC shall have
          received such a Supplemental Ruling in form and substance reasonably
          satisfactory to FMC;

               b)  Subsidiary shall deliver to FMC an Acceptable Letter of
          Credit with a face amount equal to the amount of Aggregate Assumed
          Spin-Off Tax Liabilities as security for any Tax-Related Losses that
          result if such issuance of Equity Securities or other transaction
          results in Tax-Related Losses.  Subsidiary shall keep in place the
          Acceptable Letter of Credit until the end of the Restriction Period
          (or if any claim for indemnity or claim which could give rise to such
          a claim for indemnity is pending at the end of the Restriction Period,
          the Acceptable Letter of Credit will be renewed and its face amount
          increased by an amount equal to the amount of interest that would
          accrue, during the period of renewal, on the face amount of the
          Acceptable Letter of Credit (prior to renewal and prior to increase
          pursuant to this sentence) at 110% of the highest Underpayment Rate
          for U.S. corporations in effect on the date of determination, and such
          Acceptable Letter of Credit will continue to be renewed and, upon each
          such renewal, its face amount so increased, until such claim is
          finally resolved) or, in the event a Non-Renewal Notice has been given
          with respect to such Acceptable Letter of Credit, replace such
          Acceptable Letter of Credit with a substitute Acceptable Letter of
          Credit.  FMC may, in its discretion, seek a Supplemental Ruling with
          respect to such issuance of Equity Securities or other transaction, in
          which case Subsidiary shall (and shall cause each Subsidiary Affiliate
          to) cooperation with FMC and use its reasonable best efforts to seek
          to obtain, as expeditiously as possible, such Supplemental Ruling.
          FMC may at any time, in its discretion, present the Acceptable Letter
          of Credit for payment in its face amount in the event that it or an
          FMC Affiliate incurs a Tax-Related Loss or Subsidiary fails to renew
          or replace the Acceptable Letter of Credit as aforesaid by the date
          which is 30 days prior to the expiration date of the Acceptable Letter
          of Credit then in effect. Subsidiary shall remain liable for any
          obligations under this Agreement to the extent the Acceptable Letter
          of Credit is insufficient to satisfy such obligations or is
          unavailable for drawing for any reason.  In the event the amount drawn
          under the Acceptable Letter of Credit exceeds the amount of
          Subsidiary's obligations under this Agreement, such excess, as
          reasonably determined by FMC, shall be paid to Subsidiary at the end
          of the Restriction Period (or if any claim for indemnity or claim
          which could give rise to such a claim for indemnity is pending at the
          end of the Restriction Period, when such claim is finally resolved)
          with interest on such excess calculated using the Underpayment Rate
          for the period from the day FMC

                                      -30-
<PAGE>

          received such payment through the Business Day immediately prior to
          the day such payment is made to Subsidiary;

               c)  If and only if following the transaction at issue, (x)
          Subsidiary or any Subsidiary Affiliate will not have issued in the
          aggregate (including, for these purposes, stock issued in connection
          with the IPO and any sale of stock of Subsidiary or any Subsidiary
          Affiliate by FMC or any FMC Affiliate) 40% or more (by vote or value)
          of its outstanding stock (determined immediately following such
          transaction) taking into account all issuances of (and agreements to
          issue) Equity Securities (and assuming the exercise of all such Equity
          Securities and the closing of all such agreements) from the point in
          time immediately prior to the IPO to the date immediately following
          such transaction and (y) Subsidiary will be the surviving entity if
          such transaction is a merger (excluding, for these purposes, any
          reverse subsidiary merger in which Subsidiary is the surviving entity
          in which case this clause (c) shall not apply and Subsidiary shall be
          required to satisfy the requirements of clause (a) or (b) above),
          Subsidiary may, in lieu of obtaining a Supplemental Ruling described
          in clause (a) above or delivering an Acceptable Letter of Credit as
          described in clause (b) above, obtain and deliver to FMC an
          appropriate Board Certification and an Unqualified Tax Opinion (at its
          own expense), in form and substance reasonably satisfactory to FMC and
          on which FMC may rely, from Qualified Tax Counsel that such
          transaction will not affect the treatment of the Spin-Off and the
          Internal Distribution under Section 355 of the Code; or

               d)  If and only if following the transaction at issue, (x)
          Subsidiary or any Subsidiary Affiliate will not have issued in the
          aggregate (including, for these purposes, stock issued in connection
          with the IPO and any sale of stock of Subsidiary or any Subsidiary
          Affiliate by FMC or any FMC Affiliate) 35% or more (by vote or value)
          of its outstanding stock (determined immediately following such
          transaction) taking into account all issuances of (and agreements to
          issue) Equity Securities (and assuming the exercise of all such Equity
          Securities and the closing of all such agreements) from the point in
          time immediately prior to the IPO to the date immediately following
          such transaction and (y) Subsidiary will be the surviving entity if
          such transaction is a merger (excluding, for these purposes, any
          reverse subsidiary merger in which Subsidiary is the surviving entity
          in which case this clause (d) shall not apply and Subsidiary shall be
          required to satisfy the requirements of clause (a) or clause (b)
          above), Subsidiary may, in lieu of obtaining a Supplemental Ruling
          described in clause (a) above or delivering an Acceptable Letter of
          Credit as described in clause (b) above, obtain and deliver to FMC an
          appropriate Board Certification.

          (2)  FMC Restrictions.  FMC agrees that it will not take or fail to
take, or permit any FMC Affiliate to take or fail to take, any action where such
action or failure to act would be inconsistent with any material, information,
covenant or representation in the Ruling Documents, Supplemental Ruling
Documents, Ruling or Supplemental Ruling.

               (b)  Liability for Undertaking Certain Actions.

                                      -31-

          (1)  Subsidiary Liability.  Subsidiary and each Subsidiary Affiliate
shall be responsible for one hundred percent (100%) of any and all Tax-Related
Losses that are attributable to, or result from, any act or failure to act
described in Section 10.1(a)(1) of this Agreement by Subsidiary or any
Subsidiary Affiliate.  Subsidiary and each Subsidiary Affiliate shall jointly
and severally indemnify FMC, each FMC Affiliate and their directors, officers
and employees and hold them harmless from and against any such Taxes.

          (2)  FMC Liability. FMC and each FMC Affiliate shall be responsible
for one hundred percent (100%) of any and all Tax-Related Losses that are

Ruling or Supplemental Ruling in its sole and exclusive discretion.  If FMC
determines to obtain a Ruling or a Supplemental Ruling, Subsidiary shall (and
shall cause each Subsidiary Affiliate to) cooperate with FMC and take any and
all actions reasonably requested by FMC in connection with obtaining the Ruling
or Supplemental Ruling (including, without limitation, by making any
representation or covenant or providing any materials or information requested
by any Tax Authority; provided that, Subsidiary shall not be required to make
(or cause any Subsidiary Affiliate to make) any representation or covenant that
is inconsistent with historical facts or as to future matters or events over
which it has no control).  In connection with obtaining a Ruling or Supplemental

               (d)  Supplemental Rulings at Subsidiary's Request. FMC agrees

Ruling issued previously, and (ii) compliance on the part of Subsidiary or any
Subsidiary Affiliate with its obligations under Section 10.1 of this Agreement.
Further, in no event shall FMC file any Supplemental Ruling under this Section

Supplemental Ruling and any materials, appendices and exhibits submitted or
filed therewith (the "Supplemental Ruling Documents") and (2) all information
and representations, if any, relating to Subsidiary and any Subsidiary Affiliate
contained in the Supplemental Ruling Documents are true, correct and complete in

Tax-Related Losses that are attributable to, or result from any acquisition of
stock of Subsidiary or any Subsidiary Affiliate by any person or persons
(including, without limitation, as a result of an issuance of Subsidiary stock
or a merger of another entity with and into Subsidiary or any Subsidiary
Affiliate) or any acquisition of assets of Subsidiary or any Subsidiary
Affiliate (including, without limitation, as a result of a merger) by any person
or persons. Subsidiary and each Subsidiary Affiliate shall jointly and severally
indemnify FMC, each FMC Affiliate and their directors, officers and employees
and hold them harmless from and against any such Tax-Related Losses.

               (f)  Liability for Breach of Representation.  Each of FMC and
Subsidiary hereby represents that (1) it will read the Ruling Documents and
Supplemental Ruling Documents prior to the date submitted, (2) all information
contained in such Ruling Documents and Supplemental Ruling Documents that
concerns or relates to such party or any affiliate of such party will be true,

If any Tax Authority withdraws all or any portion of a Ruling or Supplemental
Ruling issued to FMC in connection with the Spin-Off because of a breach by

10.1(f), Subsidiary and each Subsidiary Affiliate shall be responsible for one
hundred percent (100%) of any Tax-Related Losses resulting from such breach.  In
such event, Subsidiary and each Subsidiary Affiliate shall jointly and severally
indemnify FMC, each FMC Affiliate and their directors, officers and employees

Affiliate of a representation made in this Section 10.1(f), FMC and each FMC
Affiliate shall be responsible for one hundred percent (100%) of any Tax-Related
Losses resulting from such breach.  In such event, FMC and each FMC Affiliate
shall jointly and severally indemnify Subsidiary, each Subsidiary Affiliate and
their directors, officers and employees and hold them harmless from and against
any such Tax-Related Losses.

          10.2 Enforcement.  The parties hereto acknowledge that irreparable
harm would occur in the event that any of the provisions of this Section 10 were
not performed in accordance with their specific terms or were otherwise
breached.  The parties hereto agree that, in order to preserve the Tax-Free
Status of the Spin-Off, injunctive relief is appropriate to prevent any
violation of the foregoing covenants, provided, however, that injunctive relief
                                      --------  -------
shall not be the exclusive legal or equitable remedy for any such violation.

          10.3   Information for Shareholders. FMC shall provide each

     Section 11. Special Allocations With Respect to Certain Tax Matters
                 -------------------------------------------------------

          11.1   Foreign Sales Corporation Matters.  For purposes of this
Agreement, and notwithstanding any contrary provision contained in this
Agreement, any Tax Detriment arising out of or relating to any disallowance or
denial of any Tax Benefits claimed by FMC, any FMC Affiliate, Subsidiary or any
Subsidiary Affiliate relating to a Technologies Business in any Pre-
Deconsolidation Period under (i) Subpart C of Part III of Subchapter N of
Chapter 1 of the Code (as in effect prior to the passage of the FSC Repeal and
Extraterritorial Income Exclusion Act of 2000) or Section 114 of the Code or
(ii) any similar provision or benefit accorded under foreign laws, shall be
allocated to, and the amount of such Tax Detriment shall be payable by,
Subsidiary.  For the avoidance of doubt, it is the intent of the parties to this
agreement that Subsidiary be liable for the amount of any such Tax Detriment
relating to any such disallowance or denial of any such Tax Benefits regardless
of whether such Tax Benefit arose before or after the Separation.  The amount of
such Tax Detriment shall be calculated without giving effect to any unused Tax
Assets of FMC or any FMC Affiliate that becomes available for use and is used as
a result of such Tax Detriment.

          11.2   Intercompany Pricing Adjustments. For purposes of this
Agreement, and notwithstanding any contrary provision contained in this
Agreement, any Tax Detriment arising out of or relating to any adjustment by the
Service or any foreign Tax authority pursuant to Section 482 or any similar
provision of foreign Tax law of any Tax Item relating to a Technologies Business
shall be allocated to, and payable by, the Subsidiary. For the avoidance of
doubt, it is the intent of the parties to this agreement that Subsidiary be
liable for the amount of any such Tax Detriment relating to any such adjustment
regardless of whether such adjustment relates to a taxable period ending before
or after the Separation. The amount of such Tax Detriment shall be calculated
without giving effect to any unused Tax Assets of FMC or any FMC Affiliate that
becomes available for use and is used as a result of such Tax Detriment.

          11.3   Permanent Establishment Related Adjustments. For purposes of
this Agreement, and notwithstanding any contrary provision contained in this
Agreement, any Tax Detriment arising out of or relating to the determination by
a foreign Tax Authority that FMC, any FMC Affiliate, Subsidiary or any
Subsidiary Affiliate maintained a "permanent establishment" (within the meaning
of the applicable tax treaty) or other taxable presence in such jurisdiction
during any Pre-Deconsolidation Period, shall be allocated 100% to Subsidiary to
the extent the Tax Detriment relates to or arises out of the Technologies
Business. For the avoidance of doubt, it is the intent of the parties to this
agreement that Subsidiary be liable for 100% of the amount of the Tax Detriment
that relates to the Technologies Business regardless of whether such amount
relates to a taxable period ending before or after the Separation. The amount of
such Tax Detriment shall be calculated (i) without giving effect to any unused
Tax Assets of FMC or any FMC Affiliate that becomes available for use and is
used as a result of such

                                      -34-
<PAGE>

Tax Detriment and (ii) after giving effect to the increase in Taxes (that relate
to the Chemical Business) for which FMC or any FMC Affiliate is liable.

          11.4   1994 Tax Case.  FMC has filed a certain Tax case in the United
States Tax Court against the Commissioner of Internal Revenue, Docket No. 2317-
00, with respect to Tax year 1994 (the "FMC Tax Case").  FMC and Subsidiary
hereby agree, notwithstanding any contrary provision contained herein, to
allocate responsibility, liability and Refunds for the FMC Tax Case as follows:

                 (i)    FMC will pay for all out of pocket expenses relating to
     the prosecution of the FMC Tax Case;

                 (ii)   FMC shall have the sole right to control the prosecution
     of the FMC Tax Case, provided that FMC shall provide Subsidiary with a
     timely and reasonably detailed account of each stage of the FMC Tax Case,
     shall consult with Subsidiary before taking any significant action in
     connection with the FMC Tax Case and shall prosecute the FMC Tax Case
     diligently and in good faith as if FMC were the only party in interest;

                 (iii)  To the extent that the Service prevails in the FMC Tax
     Case, Subsidiary shall be responsible for, and shall pay to FMC on demand,
     the first $4.3 million of any payment (including payment of Taxes, interest
     or penalties) due the Service;

                 (iv)   Any amounts due the Service in excess of $4.3 million
     shall be the sole responsibility of FMC;

                 (v)    To the extent that as a result of the disposition of the
     FMC Tax Case, FMC is entitled to a Refund of Taxes (including interest),
     the amount of such Refund will be allocated equally between the parties;

                 (vi)   FMC shall pay any amounts due to Subsidiary pursuant to
     (v) hereof within thirty (30) Business Days of receipt of such amounts from
     the Service;

                 (vii)  The parties intend that for financial accounting
     purposes, any payment made by FMC to Subsidiary under (v) hereof shall be
     treated as an increase in tax expense for FMC and a decrease in tax expense
     for Subsidiary and the parties shall use reasonable efforts to obtain such
     treatment; and

                 (viii) The obligation of FMC to make payments to Subsidiary
     under (v) hereof shall cease with respect to tax years ending after the
     2004 tax year, and no payments shall be due to Subsidiary with respect to
     Refunds received after the ending of such tax year.

          11.5   Notwithstanding any other provision of this Agreement, in the
event that prior to or in connection with the Restructuring a foreign Subsidiary
Affiliate makes a payment to Parent which is treated as a Qualifying Pre-
Restructuring Foreign Dividend, FMC shall be liable (and Subsidiary shall not be
liable) for any Taxes of Subsidiary resulting from, arising out of or relating
to such Qualifying Pre-Restructuring Foreign Dividend.

other items between the Technologies Business and the Chemicals Business in
connection with any aspect of the matters described in sections 11.1, 11.2,
11.3, 11.4 or 11.5, such allocation shall be made by FMC in good faith and in
