                           and demanding that the Issuer remedy the same, shall
                           have been given by registered or certified mail,
                           return receipt requested, to the Issuer; or

                  (iv)     any event or condition shall occur which results in
                           the acceleration of the maturity of any Debt or

                           time or both, would enable the holder of such Debt or

                           involuntary case or proceeding; (C) consents to the

                           debts as the same become due;

         then, subject to the last paragraph of this Section 3(c), set forth

         the payment date of the principal amount hereof applying an interest
         rate of twelve percent (12%) per annum less (ii) any prepayments made
         pursuant to Section 3(b), above.

4.       REIMBURSEMENT OF EXPENSES. The Issuer shall reimburse the Noteholder,
         on demand, for any and all costs and expenses, including reasonable
         attorneys' fees and court costs, incurred by the Noteholder in

         of the foregoing.

5.       POWERS AND REMEDIES CUMULATIVE; DELAY OR OMISSION NOT A WAIVER OF
         DEFAULT.

         (a)      No right or remedy herein conferred upon or reserved to the
                  Noteholder is intended to be exclusive of any other right or
                  remedy, and every right and remedy shall, to the extent
                  permitted by law, be cumulative and in addition to every other
                  right and remedy given hereunder or now or hereafter existing
                  at law or in equity or otherwise. The assertion or employment
                  of any right or remedy hereunder, or otherwise, shall not
                  prevent the concurrent assertion or employment of any other
                  appropriate right or remedy.

         (b)      No delay or omission of the Noteholder to exercise any right
                  or power accruing upon any Default or Event of Default
                  occurring and continuing as aforesaid shall impair any such
                  right or power or shall be construed to be a waiver of any
                  such Default or Event of Default or an

<PAGE>

                  acquiescence therein; and every power and remedy given by this
                  Note or by law may be exercised from time to time, and as
                  often as shall be deemed expedient, by the Noteholder.

6.       WAIVER OF PAST DEFAULTS.

         (a)      The Noteholder may waive any past Default or Event of Default
                  hereunder and its consequences. In the case of any such
                  waiver, the Issuer and the Noteholder shall be restored to
                  their former positions and rights hereunder, respectively; but
                  no such waiver shall extend to any subsequent or other Default
                  or impair any right consequent thereon.

         (b)      Upon any such waiver, such Default shall cease to exist and be
                  deemed to have been cured and not to have occurred, and any
                  Default or Event of Default arising therefrom shall be deemed
                  to have been cured, and not to have occurred for every purpose
                  of this Note; but no such waiver shall extend to any
                  subsequent or other Default or Event of Default or impair any
                  right consequent thereon.

7.       SUBORDINATION.

                  certain promissory note dated July 3, 2001 in the original

                  Note; or (ii) any other promissory note issued
                  contemporaneously herewith pursuant to the Transaction
                  Agreement (each a "Subordinated Note and collectively, the

                  shall be redeemed or purchased directly or indirectly by the

                  payment or purchase or immediately after giving effect
                  thereto, (x) there shall exist a default in any payment with
                  respect to the Senior Indebtedness; or (y) there shall have
                  occurred any other default or event of default as those terms
                  may be defined in the instrument under which such Senior
                  Indebtedness is outstanding (other than a default in the
                  payment of amounts due thereon) with respect to the Senior
                  Indebtedness permitting the holders thereof to accelerate the
                  maturity thereof, and such default or event of default shall
                  not have been cured or waived or shall not have ceased to
                  exist.

         (b)      Subject to payment in full of the Senior Indebtedness, the
                  holders of the Subordinated Notes shall be subrogated to the
                  rights of the holders of Senior Indebtedness to receive
                  payments or distributions of the assets of the Issuer made on
                  such Senior Indebtedness until all principal and interest on
                  the Subordinated Notes shall be paid in full; and for purposes
                  of such subrogation, no payments or distributions to the
                  holders of Senior Indebtedness of any cash, property or
                  securities to which any holders of the Subordinated Notes
                  would be entitled except for the subordination provisions of
                  this Section 7 shall, as between the holders of the
                  Subordinated Notes and the Issuer and/or its creditors (other
                  than the holders of the Senior Indebtedness) be deemed to be a
                  payment on account of the Senior Indebtedness.

         (c)      The provisions of this Section 7 are and are intended solely
                  for the purposes of defining the relative rights of the
                  holders of the Subordinated Notes and the holders of Senior
                  Indebtedness and nothing in this Section 7 shall impair, as
                  between the Issuer and any holders of the Subordinated Notes,
                  the obligation of the Issuer, which is unconditional and
                  absolute, to pay to the holders of the Subordinated Notes the
                  principal thereof and interest thereon, in accordance with the
                  terms of the Subordinated Notes, nor shall anything herein
                  prevent any holders of the Subordinated Notes from exercising
                  all remedies otherwise permitted by applicable law or
                  hereunder upon default, subject to the rights set forth above
                  of holders of Senior Indebtedness to receive cash, property or
                  securities otherwise payable or deliverable to the holders of
                  the Subordinated Notes.

         (d)      Upon any payment (including by redemption) which is not a
                  payment in full of all of the principal amount and accrued
                  interest of all outstanding Subordinated Notes, the aggregate
                  amount of the payments shall be allocated to all the

such returns. Each Subsidiary agrees to furnish Parent, in the manner and within
the time requested, with any and all information necessary to prepare such
Combined Return.

         5. Non-Federal Income Tax.

                  (a) With respect to each jurisdiction for which Parent files a
         Combined Return pursuant to Section 4 herein, Parent shall compute the
         non-federal Income Tax liability of the Affiliated Group as described
         in Section 4 above.

                  (b) With respect to each jurisdiction for which Parent files a
         Combined Return pursuant to Section 4 herein and for each Subsidiary,
         Parent shall compute the non-federal Income Tax liability of the
         Affiliated Group exclusive of all items of income, deduction, and
         credit generated by such Subsidiary for each taxable year.

         Parent shall also compute the non-federal Income Tax which would be due
         and payable by such Subsidiary for such taxable year to such

         and such jurisdiction (the "Allocated Non-Federal Tax Liability").

                  (e) Based upon the calculations set forth in Sections 5(a) and
         (b) above, each taxable year Parent shall pay to each Subsidiary
         included in a Combined Return the

                                      -3-
<PAGE>

         amount equal to twenty percent (20%) of the incremental non-federal
         Income Tax benefit (the "Allocated Non-Federal Tax Benefit") of having
         such Subsidiary become or continue to be a member of the Affiliated
         Group.

         6. Payment. For each Estimated Tax Period, the portion of the Allocated
Federal Tax Liability, the Allocated Non-Federal Tax Liability, the Allocated
Federal Tax Benefit and the Allocated Non-Federal Tax Benefit computed under
paragraphs 3 and 5 hereof allocable to such Estimated Tax Period shall be due
and payable no later than ten days prior to the Estimated Tax Installment Date
on which such Estimated Tax Period ends. All payments to be made by any party
under this Agreement may be netted against payments due to such party, either
under this Agreement or otherwise (including, but not limited to, pursuant to
the Intercompany Note).

         7. Characterization. Parent and each Subsidiary shall treat any
payments made from Subsidiary to a higher-tier Subsidiary or to Parent under
this Agreement as a distribution from such Subsidiary to the higher-tier
Subsidiary or Parent with respect to the distributee's stock in the distributor.
Parent and each Subsidiary shall treat any payments made from Parent or from a
higher-tier Subsidiary to such Subsidiary under this Agreement as a contribution
to the capital of such Subsidiary by Parent or the higher-tier Subsidiary.

         8. Earnings and Profits. For purposes of determining the earnings and
profits of each member of the Affiliated Group pursuant to Code Section 1552 and
the Treasury Regulations thereunder, the parties hereto agree to allocate the
consolidated federal income tax liability among the Affiliated Group using the
method set forth in Code Section 1552(a)(2) and the Treasury Regulations
thereunder. A similar rule shall apply to the allocation of non-federal Income
Tax liability in determining earnings and profits pursuant to any provision of
non-federal Income Tax law analogous to Code Section 1552 and the Treasury
Regulations thereunder.

         9. Calculation. The calculation of the Allocated Federal Tax Liability,
Allocated Non-Federal Tax Liability, Allocated Federal Tax Benefit, and
Allocated Non-Federal Tax Benefit for each Subsidiary shall be determined in
good faith by Parent. If Parent and a Subsidiary fail to agree on the
calculations required to be made pursuant to this Section 9 with respect to such
Subsidiary, the dispute shall be resolved within ninety (90) days of the date
such calculations were provided by Parent to the Subsidiary by a "big five"
accounting firm mutually agreed upon by Parent and the Subsidiary. The
determination of the accounting firm shall be binding upon both Parent and the
Subsidiary. The costs, expenses and fees of the accounting firm shall be borne
equally by Parent and the Subsidiary.

         10. Administration. The provisions of this Agreement shall be
administered by Parent for the benefit of all members of the Affiliated Group.

         11. Adjustments to Income Tax Liability. If the consolidated federal
Income Tax liability, or the Income Tax liability of any combined, consolidated,
or unitary group, is adjusted for any taxable period, whether by means of an
amended return, claim for refund, audit by the IRS or other taxing authority, or
by a final judgment by a court of competent jurisdiction or other governmental
authority, the Allocated Federal Tax Liability, Allocated Non-Federal Tax
Liability, Allocated Federal Tax Benefit, and Allocated Non-Federal Tax Benefit
under paragraphs 3 and 5 hereof shall be recomputed to give effect to such
adjustments. The

                                      -4-
<PAGE>

difference between the recomputed amounts and such originally computed amounts
shall be paid by Parent to Subsidiaries within ten days after the refund is
received by Parent, or to Parent by Subsidiaries within ten days after a
Subsidiary receives notice of such liability from Parent, as the case may be,
along with interest at the same rate which the Income tax deficiency or refund
described in this Section 11 bears. Any penalty shall be allocated upon such
basis as Parent deems just and proper in view of all applicable circumstances.

         12. Term.

                  (a) This Agreement shall apply to the taxable year ending
         December 31, 2001, and all subsequent taxable years through the due
         date of the Intercompany Note, unless both Parent and Subsidiaries
         agree in writing to terminate the Agreement. Notwithstanding any
         termination, this Agreement shall continue in effect with respect to
         any payment or refunds due for all taxable periods prior to
         termination.

                  (b) If a Subsidiary leaves the Affiliated Group, it shall be
         bound by this Agreement for all taxable periods, or portions thereof,
         during which such Subsidiary was a member of the Affiliated Group.

         13. Costs. Parent will have the responsibility for conducting all IRS
examinations for the Affiliated Group, and all audits, inquiries or other
proceedings by a governmental authority involving any Combined Returns. All
expenses of the examination and of defending any adjustments or proposed
adjustments which are directly identifiable with a Subsidiary shall be billed
to, and paid by, such Subsidiary. In addition, all costs and expenses not
directly identifiable with Parent or a Subsidiary will be allocated by Parent in
an equitable manner. Subsidiaries agree that any adjustment to taxable income or
loss arising out of an examination of Parent by the IRS or another taxing
authority will be computed on the basis of agreements reached by Parent and the
IRS or such taxing authority, or on the basis of a decision of the Tax Court or
other courts of competent jurisdiction, where applicable. The redetermined tax
liability resulting from such adjustment shall be used to determine the amount
due under paragraph 8 of this Agreement.

         14. Change in Law. Any alteration, modification, addition, deletion, or
other change in the consolidated income tax return provisions of the Code or the
Treasury Regulations, or to the provisions of any state, local or foreign Income
Tax law relating to combined, consolidated or unitary groups, shall
automatically be applicable to this Agreement.

         15. Miscellaneous.

                  (a) Except as otherwise provided herein, this Agreement
         cancels and supersedes any and all previously existing agreements
         relating to the sharing of any federal, state, local or foreign Income
         Tax liabilities.

                  (b) This Agreement shall bind and inure to the respective
         successors and assigns of the parties hereto.

                  (c) This Agreement shall be governed by the laws of the State
         of Delaware.
