deduction, loss or credit was not actually utilized (by either a member of the
Controlled Group or a member of the Distributing Group) in the actual

State Income Tax Return in question, such Tax Item shall not be taken into
account in determining Stand-Alone Tax Liability with respect to such

negative), Controlled Co. shall be entitled to a payment from Distributing Co.
in accordance with Section 5.4(b)(1).

                                      -12-

        For purposes of this Section 2.3(b)(ii), the determination and payment
of estimated Taxes (including the determination and payment of any Tax required
to be paid with a request for an extension of time to file a Tax Return) shall
not be treated as an Adjustment.

        2.4. Allocation of Other Taxes. Except as provided in Section 2.5, all
Taxes other than those specifically allocated pursuant to Sections 2.2 and 2.3
shall be allocated to the legal entity on which the legal incidence of the Tax
is imposed and Controlled Co. shall be liable for all Taxes imposed on any
member of the Controlled Group. The Companies believe that there is no Tax not
specifically allocated pursuant to Sections 2.2, 2.3 or 2.5 which is legally
imposed on more than one legal entity (e.g., joint and several liability);
however, if there is any such Tax, it shall be allocated using principles
similar to those set forth in Sections 2.2, 2.3 and 2.5, as determined by
Distributing Co. in its sole discretion.

        2.5. Transaction and Other Taxes. Controlled Co. shall be liable for,
and shall indemnify and hold harmless the Distributing Group Indemnified Parties
from and against:

        (a) any Transfer Taxes;

        (b) any Distribution Taxes and any Indemnifiable Losses, except to the
extent such Distribution Taxes or Indemnifiable Losses are primarily the direct
and proximate result of a Distributing Co. Prohibited Action (as determined by
Distributing Co. in its reasonable discretion); and

        (c) any Restructuring Income Taxes.

        2.6. Allocation of Unused Tax Attributes. Unused Tax attributes for
Pre-Distribution Periods shall be allocated between the Groups in accordance
with the Code and the Treasury Regulations (or comparable provisions of other
Tax Law), or, where no treatment is specifically provided or required, as
determined by Distributing Co. in its sole discretion.

        Section 3. Proration of Tax Items for Straddle Periods.

        3.1. General Method of Proration. In the case of any Straddle Period
(including the Pre-Distribution Period of the Controlled Group ending on the
Distribution Date and the Post-Distribution Period of the Controlled Group
beginning on the day after the Distribution Date, if the taxable period of the
Distributing Group does not end on the Distribution Date), Tax Items shall be
apportioned between Pre-Distribution Periods and Post-Distribution Periods in
accordance with the principles of Treasury Regulations Section
1.1502-76(b)(2)(ii) if and to the extent that Distributing Co. (in its sole
discretion) elects to have such principles apply (and, if Distributing Co.
elects to have such principles apply, as applied by Distributing Co. in its sole
discretion).

<PAGE>
                                      -13-

        3.2. Extraordinary Items. In determining the apportionment of Tax Items
between Pre-Distribution Periods and Post-Distribution Periods, any Tax Items
arising in connection with the Distribution or any transactions undertaken in
preparation for the Distribution shall be treated as extraordinary items
described in Treasury Regulations Section 1.1502-76(b)(2)(ii)(C) and shall be
allocated to Pre-Distribution Periods to the extent and in the manner determined
by Distributing Co. in its sole discretion.

        Section 4. Preparation and Filing of Tax Returns.

        4.1. General. Except as otherwise provided in this Section 4, Tax
Returns shall be prepared and filed when due (including extensions) by the
person obligated to file such Tax Returns under the Code or applicable Tax Law.
The Companies shall provide, and shall cause their Affiliates to provide,
assistance and cooperate with one another in accordance with Section 7 with
respect to the preparation and filing of Tax Returns, including providing
information required to be provided in Section 7.

        4.2. Distributing Co.'s Responsibility. Distributing Co. shall prepare
and file, or cause to be prepared and filed:

                (a) all Distributing Co. Federal Consolidated Tax Returns;

                (b) all Consolidated or Combined State Income Tax Returns;

                (c) all other Tax Returns for or that include only members of
        the Distributing Group; and

                (d) to the extent Distributing Co. so elects at any time, any
        Tax Returns (not described in clauses (a), (b) or (c)) with respect to
        Taxes for which any member of the Distributing Group may be or become
        liable directly or secondarily (including, without limitation, Transfer
        Taxes).

        Any Tax Returns prepared and filed by Distributing Co. under this
Section 4.2 or under Section 4.3 shall be prepared exclusively by Distributing
Co. in its sole discretion, and neither Controlled Co. nor any other member of
the Controlled Group shall have any right to review or comment on the
preparation of such Tax Returns or to consent or withhold consent to the filing
of such Tax Returns (except as expressly provided in Section 4.5).

        4.3. Controlled Co.'s Responsibility. Controlled Co. shall prepare and
file, or shall cause to be prepared and filed, (i) all Tax Returns required to
be filed after the Distribution Date by any member of the Controlled Group with
respect to Separate Company Taxes and (ii) any other Tax Return (required to be
filed after the Distribution Date) for or that includes any member of the
Controlled Group that Distributing Co. does not elect to prepare and file

<PAGE>
                                      -14-

pursuant to Section 4.2(d). In the case of each Tax Return (if any) described in
clause (ii) of the preceding sentence, Distributing Co. shall be given an
opportunity to review and comment on such Tax Return (a draft copy of which
shall be provided to Distributing Co. no later than 30 days prior to the due
date for filing such Tax Return) and such Tax Return shall not be filed without
the prior written consent of Distributing Co. (which may be given or withheld in
Distributing Co.'s sole discretion); provided that, if Distributing Co. fails to
provide its consent at least 10 days prior to the due date for filing such Tax
Return, Distributing Co. shall assume exclusive control of, and shall be
responsible for finalizing and filing, such Tax Return. Distributing Co. shall
also be given an opportunity to review and comment on the consolidated federal
income tax return of the Controlled Group for the short period beginning the day
after the Distribution Date (a draft copy of which shall be provided to
Distributing Co. no later than 30 days prior to the due date for filing such Tax
Return), and such Tax Return shall be revised by Controlled Co. prior to filing
to include any changes requested by Distributing Co. (in Distributing Co.'s sole
discretion) and shall not be amended after filing without Distributing Co.'s
prior written consent (which may be given or withheld in Distributing Co.'s sole
discretion). No member of the Controlled Group or any of its Affiliates shall
take any position, on any Tax Return filed on or after the Distribution Date,
that could have adverse Tax consequences to Distributing Co. or any of its
Subsidiaries with respect to any Tax Period ending on or prior to, or including,
the Distribution Date.

        4.4. Consolidated or Combined Returns. The Companies will elect and
join, and will cause their respective Affiliates to elect and join, in filing
consolidated, unitary, combined, or other similar joint Tax Returns (to the
extent each entity is eligible to join in such Tax Returns) as and to the extent
determined by Distributing Co. in its sole discretion.

        4.5. Execution of Certain Tax Returns Prepared by Distributing Co. In
the case of any Tax Return which is prepared and filed by Distributing Co. under
Sections 4.2(d) or 4.3 but is required by law to be signed by Controlled Co. (or
by its authorized representative), Controlled Co. shall be required to sign such
Tax Return unless there is no reasonable basis for the tax treatment of any
material item reported on the Tax Return.

        4.6. Adjustment Requests.

        (a) Distributing Co. Consent Required for Adjustment Requests Relating
to Consolidated or Combined Income Tax. Unless Distributing Co. consents in
advance in writing, which consent shall be granted or withheld in Distributing
Co.'s sole discretion, (i) no Adjustment Request shall be filed with respect to
any Consolidated or Combined Income Tax and (ii) any elections available to
members of the Controlled Group to waive the right to claim in any
Pre-Distribution Period any Carryback arising in a Post-Distribution Period with
respect to any Consolidated or Combined Income Tax shall be made, and no
affirmative election shall be made to claim any such Carryback. Any Adjustment
Request which Distributing Co. consents to make under this Section 4.6 shall be
prepared and filed by Distributing Co. in

<PAGE>
                                      -15-

its sole discretion. In connection with any Adjustment Request prepared and
filed by Distributing Co. with respect to any Consolidated or Combined Income
Tax (whether such Adjustment Request was requested by Controlled Co. or was
initiated by Distributing Co. on its own), Controlled Co. shall provide to
Distributing Co. all information required of the Controlled Group for the
preparation and filing of such Adjustment Request in such form and detail as
reasonably requested by Distributing Co. Notwithstanding anything to the
contrary in this paragraph (a), the consent of Controlled Co. shall not be
required for any Adjustment Request initiated by Distributing Co. or any member
of the Distributing Group with respect to any Consolidated or Combined Income
Tax (whether or not such Adjustment Request was requested by a member of the
Controlled Group).

        (b) Entitlement to the Benefit of Any Refunds or Credits with Respect to
Consolidated or Combined Income Taxes. Any Tax Benefit arising with respect to
any Adjustment of any Consolidated or Combined Income Tax (including, without
limitation, any Tax Benefit arising with respect to a Carryback to a
Pre-Distribution Period of a loss or credit of a member of the Controlled Group
arising in a Post-Distribution Period) shall belong exclusively to the
Distributing Group; it being understood that the Controlled Group shall share in
any such Tax Benefit only to the extent that such Tax Benefit results in an
adjustment in favor of Controlled Co. pursuant to Section 2.2(b) or Section
2.3(b)(ii).

        (c) Application of This Section to Certain Other Taxes. Principles
similar to those set forth in Sections 4.6(a) and (b) shall apply to Adjustments
with respect to any Tax other than a Consolidated or Combined Income Tax if,
pursuant to Section 2.4, Distributing Co. determines in its sole discretion that
any member of the Distributing Group may be or become legally responsible
(directly or secondarily) for such Tax.

        Section 5. Tax Payments and Intercompany Billings.

        5.1. Payment of Taxes with Respect to Distributing Co. Federal
Consolidated Tax Returns Originally Filed After the Distribution Date. In the
case of any Distributing Co. Federal Consolidated Tax Return that will
originally be filed after the Distribution Date:

        (a) Computation and Payment of Tax Due. Distributing Co. shall compute
the amount of Tax required to be paid to the IRS with respect to such Tax Return
(including, without limitation, any estimated Taxes) and shall pay such amount
to the IRS on or before such Payment Date.

        (b) Computation and Payment of Controlled Co. Liability with Respect to
Tax Due. Within 10 days of receiving from Distributing Co. a written request for
payment (and in no event later than five days before the corresponding Tax
payment is payable by Distributing Co. to the IRS), Controlled Co. will pay to
Distributing Co. the excess (if any) of --

<PAGE>
                                      -16-

                (i) the Stand-Alone Tax Liability (whether positive or negative)
        of the Controlled Group under Section 2.2(a) with respect to such Tax
        Return through the Payment Date in question (the "Allocated Federal Tax
        Liability"), over

                (ii) the cumulative net payments with respect to such Tax Return
        prior to such Payment Date by the members of the Controlled Group (the
        "Cumulative Federal Tax Payment").

If the Cumulative Federal Tax Payment of the Controlled Group is greater than
the Allocated Federal Tax Liability of the Controlled Group as of any Payment
Date, then Distributing Co. shall pay such excess to Controlled Co. within 10
days of Distributing Co.'s receipt of the corresponding Tax Benefit (i.e.,
through either a reduction in Distributing Co.'s otherwise required Tax payment
or a credit or refund of prior Tax payments).

        5.2. Payment of Federal Income Tax Related to Adjustments.

        (a) Adjustments Resulting in Underpayments. Distributing Co. shall pay
to the IRS when due any additional Federal Income Tax required to be paid as a
result of any Adjustment to the Tax liability with respect to any Distributing
Co. Federal Consolidated Tax Return. In connection with any Adjustment to a
Distributing Co. Federal Consolidated Tax Return (whether or not such Adjustment
results in a payment to the IRS), Distributing Co. shall compute the amount
attributable to the Controlled Group in accordance with Section 2.2(b), and
Controlled Co. shall pay to Distributing Co. any amount due under Section 2.2(b)
(as determined by Distributing Co. in its sole discretion) within 10 days of
receiving from Distributing Co. a written request for payment (and in no event
later than five days before the corresponding Tax payment is payable by
Distributing Co. to the IRS).

        (b) Adjustments Resulting in Overpayments. Within 10 days of receipt by
Distributing Co. of any Tax Benefit resulting from any Adjustment with respect
to any Distributing Co. Federal Consolidated Tax Return, Distributing Co. shall
pay to Controlled Co. any amounts due to Controlled Co. pursuant to the last
sentence of Section 2.2(b).

        5.3. Payment of State Income Tax with Respect to Returns Originally
Filed After the Distribution Date. In the case of any State Income Tax Return
that will originally be filed after the Distribution Date:

        (a) Computation and Payment of Tax Due. As provided in Section 4, the
Responsible Company shall compute the amount of Tax required to be paid to the
applicable Tax Authority with respect to such Tax Return on such Payment Date
(including, without limitation, any estimated Taxes) and:

<PAGE>
                                      -17-

                (i) if such Tax Return is with respect to a Consolidated or
        Combined State Income Tax, Distributing Co. shall pay such amount to
        such Tax Authority on or before such Payment Date; and

                (ii) if such Tax Return is with respect to any Tax other than a
        Consolidated or Combined Income Tax, the Responsible Company shall pay
        such amount to such Tax Authority on or before such Payment Date.

        (b) Computation and Payment of Controlled Co. Liability with Respect to
Tax Due. Within 10 days of receiving from Distributing Co. a written request for
payment (and in no event later than five days before the corresponding Tax
Payment is payable by Distributing Co. to the applicable Tax Authority),
Controlled Co. will pay to Distributing Co.:

                (i) in the case of any Consolidated or Combined State Income Tax
        Return, the excess (if any) of --

                        (A) the Stand-Alone Tax Liability (whether positive or
                negative) of the Controlled Group under Section 2.3(b)(i) with
                respect to such Tax Return through the Payment Date in question
                (the "Allocated State Tax Liability"), over

                        (B) the cumulative net payments with respect to such Tax
                Return prior to such Payment Date by the members of the
                Controlled Group (the "Cumulative State Tax Payment"); and

                (ii) in the case of any Tax described in Section 5.3(a)(ii) for
        which Controlled Co. is responsible under this Agreement but
        Distributing Co. is the Responsible Company, the full amount of Tax due.

If, with respect to any Consolidated or Combined State Income Tax Return
described in clause (i), the Cumulative State Tax Payment of the Controlled
Group is greater than the Allocated State Tax Liability of the Controlled Group
as of any Payment Date, then Distributing Co. shall pay such excess to
Controlled Co. within 10 days of Distributing Co.'s receipt of the corresponding
Tax Benefit.

        5.4. Payment of State Income Tax Related to Adjustments.

        (a) Adjustments Resulting in Underpayments.

                (1) Consolidated or Combined State Income Taxes. Distributing
        Co. shall pay to the applicable Tax Authority when due any additional
        State Income Tax required to be paid as a result of any Adjustment to
        the Tax liability with respect to any Consolidated or Combined State
        Income Tax Return. In connection with any Adjust-

<PAGE>
                                      -18-

        ment to a Consolidated or Combined State Income Tax Return (whether or
        not such Adjustment results in a payment to the applicable Tax
        Authority), Distributing Co. shall compute the amount attributable to
        the Controlled Group in accordance with Section 2.3(b)(ii) and
        Controlled Co. shall pay to Distributing Co. any amount due under
        Section 2.3(b)(ii) (as determined by Distributing Co. in its sole
        discretion) within 10 days of receiving from Distributing Co. a written
        request for payment (and in no event later than five days before the
        corresponding Tax payment is payable by Distributing Co. to the
        applicable Tax Authority).

                (2) Certain Other Taxes. With respect to any Tax described in
        Section 5.3(b)(ii), Distributing Co. shall pay to the applicable Tax
        Authority when due any additional Taxes required to be paid as a result
        of any Adjustment. Within 10 days of receiving from Distributing Co. a
        written request for payment (and in no event later than five days before
        any such Tax is payable by Distributing Co. to the applicable Tax
        Authority), Controlled Co. shall pay to Distributing Co. an amount equal
        to the full amount of any such Tax.

        (b) Adjustments Resulting in Overpayments.

                (1) Consolidated or Combined State Income Taxes. Within 10 days
        of receipt by Distributing Co. of any Tax Benefit resulting from any
        Adjustment with respect to any Consolidated or Combined State Income Tax
        Return, Distributing Co. shall pay to Controlled Co. any amounts due to
        Controlled Co. pursuant to the last sentence of Section 2.3(b)(ii).

                (2) Certain Other Taxes. With respect to any Tax described in
        Section 5.3(b)(ii), within 10 days of receipt by Distributing Co. of any
        Tax Benefit resulting from any Adjustment, Distributing Co. shall pay to
        Controlled Co. an amount equal to such Tax Benefit (net of any Taxes
        imposed on Distributing Co. or Distributing Co.'s Affiliates in
        connection with the receipt of such Tax Benefit).

        5.5. Payment of Separate Company Taxes. Except as otherwise provided in
Sections 5.3(a)(ii) and 5.4(a)(2), each Company shall pay, or shall cause to be
paid, to the applicable Tax Authority when due all Separate Company Taxes owed
by such Company or a member of such Company's Group.

        5.6. Computation of Underpayment and Overpayment Interest and Penalties
with Respect to Consolidated or Combined Income Taxes. In connection with any
change in the Stand-Alone Tax Liability of the Controlled Group giving rise to a
payment (by Controlled Co. to Distributing Co., or by Distributing Co. to
Controlled Co.) under Sections 5.2(a), 5.2(b), 5.4(a)(1) or 5.4(b)(1),
Distributing Co. shall determine in its sole discretion whether

<PAGE>
                                      -19-

Controlled Co. owes Distributing Co. additional amounts attributable to
underpayment interest and/or penalties and whether Distributing Co. owes
Controlled Co. additional amounts attributable to overpayment interest. These
determinations shall be made with respect to the Controlled Group on a
hypothetical stand-alone basis, in a manner consistent with the determination of
the Controlled Group's Stand-Alone Tax Liability; provided, however, that in no
event shall Controlled Co. be entitled to a payment in respect of overpayment
interest (with respect to a downward adjustment of the Controlled Group's
Stand-Alone Tax Liability) that exceeds the overpayment interest actually
received by Distributing Co. from the applicable Tax Authority (with respect to
the Adjustment that gave rise to the reduction in the Controlled Group's
Stand-Alone Tax Liability). Any amounts due under this Section 5.6 shall be paid
in addition to, and simultaneously with, the amounts due under Sections 5.2(a),
5.2(b), 5.4(a)(1) or 5.4(b)(1) to which such amounts due under Section 5.6
relate.

        5.7 Treatment of Certain Amounts Payable in Connection with Tax
Contests. If, in connection with a Tax Contest (or potential Tax Contest) that
might result in any change to the Stand-Alone Tax Liability of the Controlled
Group, Distributing Co. or any of its Affiliates (i) makes a deposit with an
applicable Tax Authority or (ii) posts a surety bond or incurs other costs or
expenses, Controlled Co. shall pay to Distributing Co. the portion of such
deposit, cost or expense that is attributable to the Controlled Group (as
determined by Distributing Co. in its sole discretion, in a manner consistent
with Distributing Co.'s determination (from time to time) of the Controlled
Group's Stand-Alone Tax Liability). Any amounts payable by Controlled Co. under
this Section 5.7 shall be paid to Distributing Co. within 10 days of Controlled
Co.'s receipt from Distributing Co. of a written request for payment (and in no
event later than five days before Distributing Co. will be required to fund the
deposit or pay the cost or expense in question). If any deposit of Tax made by
Distributing Co. that is funded in whole or in part by Controlled Co. (pursuant
to this Section 5.7) is ultimately repaid to Distributing Co. by the applicable
Tax Authority, Distributing Co. shall repay to Controlled Co. (within 10 days of
Distributing Co.'s receipt of such repayment) the portion of such deposit that
was funded by Controlled Co.

        5.8. Indemnification Payments. With respect to any indemnification
payment required under this Agreement the timing of which is not specifically
addressed elsewhere in this Section 5, the indemnifying party shall pay the
indemnified party within 10 days of receiving a written request for such
indemnification payment.

        Section 6. Interest on Late Payments. Any payment due from one Company
to the other Company under Section 5 that is not paid by the latest date
permitted for payment shall bear interest (from the latest permitted payment
date through the date of actual payment) at the Large Corporate Underpayment
Rate, compounded daily.

        Section 7. Assistance and Cooperation. Each Company shall cooperate (and
cause its Affiliates to cooperate) with the other Company and the other
Company's agents, including

<PAGE>
                                      -20-

accounting firms and legal counsel, in connection with the Tax matters covered
by this Agreement including (i) preparation and filing of Tax Returns, (ii)
determining the liability for and amount of any Taxes due (including estimated
Taxes) or the right to and amount of any refund of Taxes, (iii) examinations of
Tax Returns and (iv) any administrative or judicial proceedings in respect of
Taxes assessed or proposed to be assessed. Such cooperation shall include making
information and documents in a Company's possession (or the possession of the
Company's Affiliates) available to the other Company in accordance with Section
8. Each of the Companies shall also make available to each other, as reasonably
requested and available, personnel (including officers, directors, employees and
agents of the Companies or their respective Affiliates) responsible for
preparing, maintaining, and interpreting information and documents relevant to
Taxes, and personnel reasonably required as witnesses or for purposes of
providing information or documents in connection with any administrative or
judicial proceedings relating to Taxes. The Companies agree and acknowledge, for
the avoidance of doubt, that nothing in this Section 7 shall alter the rights
and obligations of the Companies under the other Sections of this Agreement
(including, without limitation, any right of a Company to act in its sole
discretion, or reasonable discretion or to take action without obtaining the
consent of or consulting with the other Company).

        Section 8. Tax Records.

        8.1. Retention of Tax Records. Except as provided in Section 8.2, each
Company shall preserve and keep all Tax Records exclusively relating to the
assets and activities of its respective Group for Pre-Distribution Tax Periods,
and Distributing Co. shall preserve and keep all other Tax Records relating to
Taxes of the Groups for Pre-Distribution Tax Periods, for so long as the
contents thereof may become material in the administration of any matter under
the Code or other applicable Tax Law, but in any event until the later of (i)
the expiration of any applicable statutes of limitation and (ii) seven years
after the Distribution Date. If, prior to the expiration of the applicable
statute of limitation and such seven-year period, a Company reasonably
determines that any Tax Records which it is required to preserve and keep under
this Section 8 are no longer material in the administration of any matter under
the Code or other applicable Tax Law, such Company may dispose of such records
upon 90 days' prior written notice to the other Company. Such notice shall
include a list of the records to be disposed of describing in reasonable detail
each file, book, or other records being disposed. The notified Company shall
have the opportunity, at its cost and expense, to copy or remove within such
90-day period, all or any part of such Tax Records; provided that Controlled Co.
shall have the right to copy or remove only such information as relates
exclusively to members of the Controlled Group.

        8.2. State Income Tax Returns. Tax Returns with respect to State Income
Taxes and workpapers prepared in connection with preparing such Tax Returns
shall be preserved and

<PAGE>
                                      -21-

kept, in accordance with the terms of Section 8.1, by the Company having
liability for the Tax.

        8.3. Access to Tax Records. The Companies and their respective
Affiliates shall make available to each other for inspection and copying during
normal business hours upon reasonable notice all Tax Records in their possession
to the extent reasonably required by the other Company in connection with the
preparation of Tax Returns, audits, litigation, or the resolution of items under
this Agreement.

        Section 9. Tax Contests.

        9.1. Notice. Each of the Companies shall provide prompt notice to the
other Company of any pending or threatened Tax audit, assessment or proceeding
or other Tax Contest of which it becomes aware related to Taxes for Tax Periods
for which it is indemnified by the other Company hereunder, and Controlled Co.
shall provide prompt notice to Distributing Co. of any Tax Contest arising out
of a Tax Return for which Distributing Co. was the Responsible Company (even if
Controlled Co. is the indemnifying party with respect to such Tax Contest). Such
notice shall be accompanied by copies of any notice and other documents received
from any Tax Authority in respect of any such matters. If an indemnified party
has knowledge of an asserted Tax liability with respect to a matter for which it
is to be indemnified hereunder and such party fails to give the indemnifying
party prompt notice of such asserted Tax liability, the failure to give prompt
notice shall not relieve the indemnifying party of its indemnification
obligations hereunder, except to the extent that the indemnifying party is
actually and materially prejudiced thereby.

        9.2. Control of Tax Contests.

        (a) Separate Company Taxes. Except as otherwise provided in Section
9.2(b), in the case of any Tax Contest with respect to any Separate Company Tax,
the Company having liability for the Tax shall have exclusive control over such
Tax Contest, including any settlement thereof.

        (b) Consolidated or Combined Income Taxes and Certain Other Taxes. In
the case of any Tax Contest with respect to any Consolidated or Combined Income
Tax or any other Tax (including a Transfer Tax) for which any member of the
Distributing Group may be or become liable (directly or secondarily),
Distributing Co. shall have exclusive control of such Tax Contest, including any
settlement thereof. Distributing Co. shall be the only party representing the
members of either Group before any Federal or State Tax Authority in connection
with any such audit, examination or other Tax Contest, but Distributing Co.
shall keep Controlled Co. reasonably informed of the status of any Controlled
Adjustment at issue in any such Tax Contest.

        (c) Effect of Exclusive Control. If, pursuant to Sections 9.2(a) or
9.2(b), a Company has exclusive control of a Tax Contest, such Company may
settle or compromise the Tax Contest (or any portion thereof) on any terms
deemed desirable to such Company (in its sole discretion) and, in doing so, such
Company may act solely in the best interests of such Company (even if the
settlement or compromise benefits such Company at the expense of the other
Company or the other Company's Affiliates).

        (d) Indemnifiable Loss Claims. Distributing Co. shall have exclusive
control of any Indemnifiable Loss Claims (other than any claim for Taxes brought
by a Tax Authority, which shall be governed by Section 9.2(b)), including any
settlement thereof; provided that Distributing Co. may not settle or compromise
any Indemnifiable Loss Claim without the prior written consent of Controlled
Co., not to be unreasonably withheld. Distributing Co. shall be the only party
representing any Distributing Group Indemnifiable Party in connection with any
Indemnifiable Loss Claim, but Distributing Co. shall keep Controlled Co.
reasonably informed of the status of any such claim.

        Section 10. Effective Date; Termination of Prior Intercompany Tax
Allocation Agreements. This Agreement shall become effective upon consummation
of the Distribution. Immediately prior to the Distribution, (i) all Prior
Intercompany Tax Allocation Agreements shall be terminated and (ii) any
remaining obligations under such prior agreements shall be canceled.

        Section 11. Action or Inaction Inconsistent with the Ruling Request.
Controlled Co. covenants and agrees that no member of the Controlled Group or
any of its Affiliates will take any Prohibited Action or fail to take any
Required Action unless the person acting has obtained the prior written consent
of Distributing Co. (which consent may be given or withheld in Distributing
Co.'s sole discretion). In addition, unless otherwise required by law, no member
of the Controlled Group or any of its Affiliates shall take any position on any
Tax Return or for any other Tax purpose that is inconsistent with the treatment
of the Distribution as a tax-free distribution under Section 355 of the Code
(and any applicable provision of state, local or non-U.S. law).

        Section 12. Survival of Obligations. The representations, warranties,
covenants and agreements set forth in this Agreement shall be unconditional and
absolute and shall remain in effect without limitation as to time.

        Section 13. Treatment of Payments; Tax Gross Up.

        13.1. Treatment of Tax Indemnity and Tax Benefit Payments. Except as
otherwise provided in Section 13.3, any indemnification payments or payments in
respect of Tax Benefits made by a Company to the other Company under this
Agreement shall be reported for Tax purposes by the payor and the recipient as
if such payments were distributions or capital con-

<PAGE>
                                      -23-

tributions, as appropriate, occurring immediately before the Distribution Date,
but only to the extent such payments do not relate to a Tax allocated to the
payor in accordance with Treasury Regulations Section 1.1552-1 (or under
corresponding principles of other applicable Tax Laws).

        13.2. Tax Gross Up. If, notwithstanding the manner in which any
indemnification payments were reported, there is an Adjustment to the Tax
liability of a Company as a result of its receipt of an indemnification payment,
such payment shall be appropriately adjusted (as determined by Distributing Co.,
in its sole discretion) so that the amount of such payment, reduced by the
amount of all Income Taxes payable with respect to the receipt thereof (but
taking into account all correlative Tax Benefits resulting from the payment of
such Income Taxes), shall equal the amount of the payment which the Company
receiving such payment would otherwise (but for such unintended Taxes) have
received pursuant to this Agreement.

        13.3. Interest Under This Agreement. Anything herein to the contrary
notwithstanding, to the extent one Company ("indemnitor") makes a payment of
interest to another Company ("indemnitee") under Section 6 of this Agreement,
the interest payment shall be treated as interest expense to the indemnitor
(deductible to the extent provided by law) and as interest income by the
indemnitee (includible in income to the extent provided by law). The amount of
the payment shall not be adjusted under Section 13.2 to take into account any
associated Tax Benefit to the indemnitor or increase in Tax to the indemnitee.

        Section 14. Disagreements.

        (a) Factual and Legal Determinations and Computational Matters. All
factual and legal determinations and computations required to be made under this
Agreement (including, without limitation, with respect to the amount of
Stand-Alone Tax Liability of the Controlled Group (and any changes thereto from
time to time), the amount of Transfer Taxes, Distribution Taxes, Indemnifiable
Losses and Restructuring Income Taxes, the amount of indemnification payments to
be made (from time to time) by either Company to the other Company and whether
and to what extent Section 13.2 applies to any indemnification payment to be
made hereunder) shall be made by Distributing Co. in its sole discretion and
shall be conclusively presumed to be correct absent manifest and material error,
except to the extent that this Agreement expressly provides that Distributing
Co. shall make the determination or computation in its reasonable discretion.
Accordingly, Controlled Co. may challenge a factual or legal determination or
computation made by Distributing Co. only if (i) there has been manifest and
material error on the part of Distributing Co. in making such determination or
computation or (ii) solely as to those matters where this Agreement expressly
requires Distributing Co. to use its reasonable discretion, Distributing Co.'s
exercise of its discretion was unreasonable and, in either case, Controlled Co.
shall have the burden of proving that Distributing Co.'s determination or
computation was manifestly and materially in error or represented an
unreasonable  ex-

<PAGE>
                                      -24-

ercise of discretion (as the case may be). Any such dispute will be resolved in
accordance with Article V, "Dispute Resolution" of the Distribution Agreement.

        (b) Other Decisions. Except as otherwise expressly provided in this
Agreement, any decisions required to be made under this Agreement that are not
covered by clause (a) (including, without limitation, whether and how to resolve
any Tax Contest or whether or not to make any Tax election permitted to be made
under applicable law) shall be made by Distributing Co. in its sole discretion
and, in making any such decision, Distributing Co. may act solely in its best
interests (even if Distributing Co.'s decision benefits Distributing Co. at the
expense of Controlled Co. or Controlled Co.'s Affiliates).

        (c) Disputed Payments. If there is any dispute under this Agreement
regarding the amount of any payment to be made by Controlled Co. to Distributing
Co. or any Distributing Group Indemnified Party, or by Distributing Co. to
Controlled Co., any disputed payments shall be made in accordance with
Distributing Co.'s determination, computation or decision pending the resolution
of such dispute, and any change ultimately made to Distributing Co.'s
determination shall be given effect only after such dispute is finally resolved.

        Section 15. Expenses. Except as otherwise provided in Section 14, each
Company and its Affiliates shall bear their own expenses incurred in connection
with preparation of Tax Returns, Tax Contests, and other matters related to
Taxes under the provisions of this Agreement.

        Section 16. General Provisions.

        16.1. Notices and Addresses.

to be given or made to any party under this Agreement shall be in writing and

Dear Kevin:

The purpose of this letter agreement is to memorialize the terms and conditions

terminate upon your resignation from Concord on September 30, 2002 (the
"Termination Date"). In consideration for Concord agreeing to these terms and
conditions, you agree to execute this letter agreement on or before September
30, 2002. By signing and returning this letter agreement to Concord, you agree
to the terms and conditions set forth in the numbered paragraphs below,
including the release of claims set forth in paragraph 3. Therefore, you are
advised to consult with your attorney before signing this letter and you may
take up to twenty one (21) days to do so. If you sign this letter agreement, you
may change your mind and revoke your agreement during the seven (7) day period
after you have signed it. If you do not so revoke, this letter agreement will
become a legally binding agreement between you and Concord upon the expiration
of the seven (7) day revocation period.

YOU WILL RECEIVE PAYMENT ON SEPTEMBER 30, 2002 FOR ANY UNUSED VACATION TIME
ACCRUED THROUGH THE TERMINATION DATE. ALSO, REGARDLESS OF SIGNING THIS LETTER,
YOU MAY ELECT TO CONTINUE RECEIVING GROUP MEDICAL/DENTAL INSURANCE PURSUANT TO
THE FEDERAL "COBRA" LAW, 29 U.S.C. SECTION 1161 ET SEQ. ALL PREMIUM COSTS SHALL

      paragraph are subject to applicable, if any, federal, state and local
      withholding, payroll and other taxes. Provided that you sign this letter
