Company in the Indenture (other than a covenant a default in whose performance
or whose breach is elsewhere in this Section specifically dealt with or which
has been expressly included in the Indenture solely for the benefit of a series
of Securities other than the Debentures), and continuance of such default or
breach for a period of 60 days after there has been given, by registered or
certified mail, to the Company by the Trustee or to the Company and the Trustee
by the Holders of at least 25% in aggregate principal amount of the Outstanding
Debentures a written notice specifying such default or breach and requiring it
to be remedied and stating that such notice is a "Notice of Default" hereunder;

      (4)   the entry by a court having jurisdiction in the premises of (A) a
decree or order for relief in respect of the Company in an involuntary case or
proceeding under any applicable Federal or State bankruptcy, insolvency or other
similar law or (B) a decree or order appointing a custodian, receiver,

<PAGE>

      (i)   In the event that the Property Trustee is the holder of all of the
Outstanding Debentures, the Company shall pay to the Trust (and any permitted
successor or assign under the Agreement) for so long as the Trust (or its
permitted successor or assignee) is the registered holder of any Debentures,
such additional amounts as may be necessary in order that the amount of
Distributions then due and payable by the Trust on the related Trust Preferred
Securities and Common Securities that at any time remain outstanding in
accordance with the terms thereof shall not be reduced as a result of any taxes,
duties, assessments and governmental charges of whatever nature imposed by the
United States or any other taxing authority to which the Trust has become
subject (but not including withholding taxes imposed on holders of such Trust
Preferred Securities and Common Securities) (the "Additional Interest").
Whenever in the Indenture or the Debentures there is a reference in any context
to the payment of principal of or interest on the Debentures, such reference
shall be deemed to include payment of the Additional Interest provided for in
this paragraph to the extent that, in such context, Additional Interest is, were
or would be payable in respect thereof pursuant to the provisions of this
Section and express reference to the payment of Additional Interest (if
applicable) in any provisions hereof shall not be construed as excluding
Additional Interest in those provisions hereof where such express reference is
not made.

            (D)   make any guarantee payments with respect to any guarantee by
      the Company of the indebtedness of any Subsidiary thereof or any other
      party if such guarantee ranks equally with or junior in right of payment
      to the Debentures

      (other than (a) dividends or distributions payable solely in shares of, or
      options, warrants or rights to subscribe for or purchase shares of, Common
      Stock of the Company, (b) any declaration of a dividend in connection with
      the implementation of a Rights Plan, (c) the issuance of any Capital Stock
      of the Company under any Rights Plan, or the redemption or repurchase of
      any rights distributed pursuant to a Rights Plan, (d) payments under the
      Trust Preferred Securities Guarantee, (e) reclassification of the
      Company's Capital Stock or the exchange or the conversion of one class or
      series of the Company's Capital Stock for another class or series of the
      Company's Capital Stock, (f) the purchase of

                                       6

<PAGE>
            fractional interests in shares of the Company's Capital Stock
            pursuant to the conversion or exchange provisions of such Capital
            Stock or the security being converted or exchanged, and (g)
            purchases of Common Stock related to the issuance of Common Stock or
            rights under any of the Company's benefit plans for its directors,
            officers, employees, consultants or advisors or any of the Company's
            dividend reinvestment plans);

if at such time (x) there shall have occurred and be continuing an Event of
Default under the Debentures or any event of which the Company has actual
knowledge that is, or with the giving of notice or the lapse of time, or both,
would be an Event of Default under the Debentures, and the Company has not taken
reasonable steps to cure such Event of Default (y) the Company shall be in
default with respect to its payment or other obligations under the Trust
Preferred Securities Guarantee or (z) the Company shall have given notice of its
election to begin an Extension Period as provided in Section 205 and shall not
have rescinded such notice or such Extension Period, or any extension thereof,
shall have commenced and be continuing.

            (iii) The Company also covenants with each holder of Debentures (A)
      to maintain directly or indirectly 100% ownership of the Common Securities
      of the Trust; provided, however, that any permitted successor or assignee
      of the Company hereunder may succeed to the Company's ownership of such
      Common Securities, (B) not to voluntarily terminate, wind up or liquidate
      the Trust, except (x) in connection with a prepayment in full of the
      Debentures or a distribution of the Debentures to the holders of Trust
      Preferred Securities in liquidation of the Trust or (y) in connection with
      certain mergers, consolidations or amalgamations permitted by the
      Agreement and (C) to use its commercially reasonable efforts, consistent
      with the terms and provisions of the Agreement, to cause the Trust to
      remain classified as a grantor trust and not an association taxable as a
      corporation for United States federal income tax purposes.

      (d)   In addition to any right of Direct Action granted under Section
3.8(e) of the Agreement to the holders of Trust Preferred Securities, if the
Property Trustee fails to enforce its rights under the Agreement or the
Indenture to the fullest extent permitted by law and subject to the terms of the
Agreement and the Indenture, then a holder of Trust Preferred Securities may
directly institute a proceeding against the Company to enforce the Property
Trustee's rights under the Agreement or the Indenture without first instituting
a legal proceeding against the Property Trustee or any other person.

      (e)   With respect to the Debentures issued under this Supplemental
Indenture, Section 112 of the Original Indenture is hereby replace in its
entirety as follows:

      Nothing in this Indenture or the Securities, express or implied, shall
give to any Person, other than the parties hereto, their successors hereunder
and the Holders of the Trust Securities, any benefit or any legal or equitable
right remedy or claim under this Indenture, provided, however, that so long as
any Preferred Securities remain outstanding, the Holders of Preferred Securities
may enforce the Company's obligations hereunder directly against the Company, if
(i) the Trustee fails, after written request, to enforce its rights hereunder or
(ii) any Event of Default

                                       7

<PAGE>

has occurred and is continuing and the event is attributable to the Company's
failure to pay interest or principal on the Debentures.

      SECTION 203. Amount, Form and Denominations; DTC. (a)The aggregate
principal amount of Debentures that may be issued under this Supplemental
Indenture is limited to $103,500,000, which amount shall be as set forth in any
written Company Order for the authentication and delivery of Debentures (except
as provided in Section 301(2) of the Original Indenture). The Debentures shall
be issuable only in fully registered form and, as permitted by Section 301 and
Section 302 of the Original Indenture, issuable, transferable, exchangeable or
redeemable in denominations of $25 and integral multiples thereof.

      (a)   The Debentures initially shall be issued to the Property Trustee.
Principal and interest on the Debentures issued in definitive form will be
payable, the transfer of such Debentures will be registrable and such Debentures
will be exchangeable for Debentures bearing identical terms and provisions at
the Corporate Trust Office; provided, however, that payment of interest may be
made at the option of the Company by check mailed to the registered holder at
such address as shall appear in the Security Register. Notwithstanding the
foregoing, so long as the registered holder of any Debentures is the Property
Trustee, the payment of the principal of and interest (including Compound
Interest and Additional Interest, if any) on such Debentures held by the
Property Trustee will be made at such place, or by wire transfer of immediately
available funds to such account, as may be designated by the Property Trustee.
The Security Register for the Debentures shall be kept at the Corporate Trust
Office, and the Trustee is hereby appointed Security Registrar for the
Debentures.

      (b)   In connection with a Dissolution Event, the Debentures in
certificated form may be presented to the Trustee by the Property Trustee in
exchange for one or more global Debentures in an aggregate principal amount
equal to the aggregate principal amount of all outstanding Debentures (each, a
"Global Debenture"), to be registered in the name of the Depositary, or its
nominee, and delivered by the Trustee to the Depositary for crediting to the
accounts of its participants pursuant to the instructions of the Administrative
Trustees. The Company, upon any such presentation, shall execute a Global
Debenture or Debentures in such aggregate principal amount and deliver the same
to the Trustee for authentication and delivery in accordance with the Original
Indenture and this Supplemental Indenture. Payments on the Debentures issued as
a Global Debenture will be made to the Depositary. The Depository Trust Company,
as depository ("DTC"), or its nominee, is hereby designated as "U.S. Depositary"
and Depositary" under the Original Indenture for the Global Debenture.

      If any Trust Preferred Securities are held in non book-entry certificated
form, the Debentures in certificated form may be presented to the Trustee by the
Property Trustee and any Trust Preferred Security Certificate which represents
Trust Preferred Securities other than Trust Preferred Securities held by the
Depositary or its nominee ("Non Book-Entry Trust Preferred Securities") will be
deemed to represent beneficial interests in Debentures presented to the Trustee
by the Property Trustee having an aggregate principal amount equal to the
aggregate liquidation amount of the Non Book-Entry Trust Preferred Securities
until such Trust Preferred Security Certificates are presented to the Security
Registrar for transfer or reissuance, at which

                                       8

<PAGE>

time such Trust Preferred Security Certificates will be canceled and a
Debenture, registered in the name of the holder of the Trust Preferred Security
Certificate or the transferee of the holder of such Trust Preferred Security
Certificate, as the case may be, with an aggregate principal amount equal to the
aggregate liquidation amount of the Trust Preferred Security Certificate
canceled, will be executed by the Company and delivered to the Trustee for
authentication and delivery in accordance with the Original Indenture and this
Supplemental Indenture. On issue of such Debentures, Debentures with an
equivalent aggregate principal amount that were presented by the Property
Trustee to the Trustee will be deemed to have been canceled.

      (c)   If the Depositary notifies the Company that it is unwilling or
unable to continue as Depositary for the Global Debenture or if at any time such
Depositary ceases to be a clearing agency registered under the Exchange Act,
and, in either such case, the Company does not appoint a successor Depositary
within 90 days thereafter, certificates for the Debentures will be registered
and delivered to the Holders of record. Upon receipt of a withdrawal request
from the Company, the Depositary will notify its participants of the receipt of
a withdrawal request from the Company notifying participants that they may
utilize the Depositary's withdrawal procedures if they wish to withdraw their
securities from the Depositary. To the extent that the book-entry system is
discontinued or, if the Company fails to appoint a successor Depositary,
certificates for the Debentures will be registered and delivered to the Holders
of record.

      (d)   Each Debenture issued hereunder shall provide that the Company and,
by its acceptance of a Debenture or a beneficial interest therein, the holder
of, and any Person that acquires a beneficial interest in, such Debenture agree
that for United States federal, state and local tax purposes it is intended that
such Debenture constitute indebtedness, and agree to treat the Debenture as
indebtedness for United States federal income tax purposes.

      (e)   The Debentures shall have such other terms and provisions as are set
forth in the form of Debenture attached hereto as Exhibit A (all of which
incorporated by reference in and made a part of this Supplemental Indenture as
if set forth in full at this place).

      SECTION 204. Interest.

      (a)   Each Debenture will bear interest at the rate of 7.50% per annum
(the "Coupon Rate") from and including the original date of issuance until the
principal thereof becomes due and payable, and on any overdue principal and, to
the extent that payment of such interest is enforceable under applicable law, on
any overdue installment of interest at the Coupon Rate, compounded quarterly,
payable quarterly in arrears on March 1, June 1, September 1 and December 1 of
each year (each, an "Interest Payment Date"), commencing on September 1, 2004 to
the Person in whose name such Debenture or any predecessor Debenture is
registered at the close of business on the relevant Regular Record Date, which
will be, (i) as long as the Trust Preferred Securities remain in book-entry form
(or if no Trust Preferred Securities remain outstanding, as long as the
Debentures remain in book-entry form), one Business Day prior to the relevant
Interest Payment Date and (ii) in the event the Trust Preferred Securities are
not in book-entry form (or if no Trust Preferred Securities remain outstanding,
in the event the Debentures are not in book-entry form), the Administrative
Trustees (or, if no Trust Preferred Securities remain outstanding, the Company)
will have the right to select the Regular Record

                                       9

<PAGE>

Date, which will be more than one Business Day but less than 60 Business Days
prior to the relevant Interest Payment Date, except as otherwise provided
pursuant to the provisions of Section 205 below.

      Any such interest installment not punctually paid or duly provided for
shall forthwith cease to be payable to the registered Holders on the Regular
Record Date, and may either be paid to the person in whose name the Debenture
(or one or more Predecessor Securities) is registered at the close of business
on a Special Record Date to be fixed by the Trustee for the payment of such
defaulted interest, notice whereof shall be given to the registered Holders of
this series of Debentures not less than ten days prior to such Special Record
Date, or may be paid at any time in any other lawful manner not inconsistent
with the requirements of any securities exchange on which the Debentures may be
listed, and upon such notice as may be required by such exchange, all as more
fully provided in the Original Indenture. The principal of and the interest on
the Debentures shall be payable at the office or agency of the Company
maintained for that purpose in the Borough of Manhattan, The City of New York,
in any coin or currency of the United States of America which at the time of
payment is legal tender for payment of public and private debts; provided,
however, that payment of interest may be made at the option of the Company by
check mailed to the registered Holder at the close of business on the Regular
Record Date at such address as shall appear in the Security Register.

      (b)   The amount of interest payable for any period will be computed on
the basis of a 360-day year of twelve 30-day months. Except as provided in the
following sentence, the amount of interest payable for any period shorter than a
full quarterly period for which interest is computed, will be computed on the
basis of the actual number of days elapsed per 30-day month. In the event that
any date on which interest is payable on the Debentures is not a Business Day,
then payment of interest payable on such date will be made on the next
succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay), except that, if such Business Day is in
the next succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on the date that such interest otherwise would have been payable.

      (c)   Maturity or redemption of a Debenture shall cause interest to cease
to accrue on such Debenture subject to the Company's obligation to pay interest
on overdue amounts in accordance with Section 503 of the Original Indenture and
the terms of this Supplemental Indenture and the Debentures.

      SECTION 205. Extension of Interest Payment Period.

      (a)   So long as no Event of Default with respect to the Debentures has
occurred and is continuing, the Company shall have the right, at any time and
from time to time during the term of the Debentures, to defer payments of
interest by extending the interest payment period of such Debentures not
exceeding 20 consecutive quarters (the "Extension Period"), during which
Extension Period no interest shall be due and payable; except that no Extension
Period may extend beyond the Stated Maturity. To the extent permitted by
applicable law, interest, the payment of which has been deferred because of the
extension of the interest payment period pursuant to this Section 205, will bear
interest thereon at the Coupon Rate compounded quarterly

                                       10
<PAGE>

for each quarter of the Extension Period ("Compound Interest"). At the end of
the Extension Period, the Company shall pay all interest accrued and unpaid on
the Debentures, including any Additional Interest and Compound Interest
(together, "Deferred Interest") that shall be payable to the Holders in whose
names the Debentures are registered in the Security Register on the record date
for the first Interest Payment Date after the end of the Extension Period.
Before the termination of any Extension Period, the Company may shorten or
further extend such period, provided that such period together with all such
further extensions thereof shall not exceed 20 consecutive quarters, or extend
beyond the Stated Maturity of the Debentures. Upon the termination of any
Extension Period and upon the payment of all Deferred Interest then due, the
Company may commence a new Extension Period, subject to the foregoing
requirements. No interest shall be due and payable during an Extension Period,
except at the end thereof, but the Company may prepay at any time all or any
portion of the interest accrued during an Extension Period.

      (b)   (i)   If the Property Trustee is the sole registered Holder at the
      time the Company selects an Extension Period or any shortening or
      extension thereof, the Company shall give written notice to the
      Administrative Trustees, the Property Trustee and the Trustee of its
      selection of such Extension Period or any shortening or extension thereof
      before the earlier of (x) the next succeeding date on which Distributions
      on the Trust Securities are payable, or (y) the date the Trust is required
      to give notice of the record date, or the date such Distributions are
      payable, to the NYSE or other applicable self-regulatory organization
      where the Trust Preferred Securities are then listed or to holders of the
      Trust Preferred Securities, but in any event at least one Business Day
      before such record date.

            (ii)  If the Property Trustee is not the sole Holder at the time the
      Company selects an Extension Period, the Company shall give the Holders of
      the Debentures and the Trustee written notice of its selection of such
      Extension Period or any shortening or extension thereof at least ten
      Business Days before the earlier of (x) the next succeeding Interest
      Payment Date, or (y) if the Debentures are then listed, the date the
      Company is required to give notice to the NYSE or other applicable
      self-regulatory organization or to Holders of the Debentures of the record
      date or the Interest Payment Date .

            (iii) The quarter in which any notice is given pursuant to
      subparagraphs (i) or (ii) of this paragraph (b) shall be counted as one of
      the 20 quarters permitted in the maximum Extension Period permitted under
      paragraph (a).

      (c)   The Company shall cause the Trust to give written notice of the
selection, shortening or extension of any Extension Period to the holders of the
Trust Preferred Securities.

      SECTION 206. Form of Debentures. Attached hereto as Exhibit A is a form of
the definitive Debentures.

                                 ARTICLE THREE

                          REDEMPTION OF THE DEBENTURES

      SECTION 301. Optional Redemption.

      The Debentures are redeemable prior to the Stated Maturity at the option
of the Company (i) in whole or in part, from time to time, on or after June 1,
2009 or (ii) at any time prior to June 1, 2009, in whole but not in part, within
90 days following the occurrence of a Special Event, in either case at a
redemption price (the "Redemption Price") equal to 100% of the principal amount
thereof, plus accrued and unpaid interest thereon (including Additional Interest
and Compound Interest, if any) to the date of redemption.

      The Company's right to redeem the Debentures under the preceding paragraph
shall be subject to the condition that if at the time there is available to the
Company or the Trust the opportunity to eliminate a Special Event, within 90
days following the occurrence and continuation of such Special Event, by taking
some ministerial action ("Ministerial Action"), such as filing a form or making
an election, or pursuing some other similar reasonable measure that will have no
adverse effect on the Company, the Trust or the holders of the Trust Securities
issued by the Trust and will involve no material cost, the Company shall pursue
such measures in lieu of redemption; provided further, that the Company shall
have no right to redeem the Debentures while the Company or the Trust is
pursuing any Ministerial Action pursuant to the Agreement.

      SECTION 302. Redemption Procedures.

      Notice of any redemption will be mailed at least 30 days but not more than
60 days before the Redemption Date to each Holder of Debentures to be prepaid at
its registered address. Unless the Company defaults in payment of the Redemption
Price, on and after the Redemption Date interest shall cease to accrue on such
Debentures called for redemption. If the Debentures are only partially redeemed
pursuant to Section 301, the Debentures will be redeemed pro rata or by lot or
by any other method utilized by the Trustee; provided that if, at the time of
redemption, the Debentures are registered as a Global Debenture, the Depositary
shall determine, in accordance with its procedures, the principal amount of such
Debentures held by each Depositary participant to be redeemed. The Redemption
Price shall be paid prior to 12:00 noon, New York time, on the date of such
redemption or at such earlier time as the Company determines; provided that the
Company shall deposit with the Trustee an amount sufficient to pay the
Redemption Price by 10:00 a.m., New York time, on the date such Redemption Price
is to be paid.

      SECTION 303. No Sinking Fund.

      The Debentures are not entitled to the benefit of any sinking fund.

                                       12

                                  ARTICLE FOUR

                                    EXPENSES

      SECTION 401. Payment of Expenses.

      In connection with the offering, sale and issuance of the Debentures and
in connection with the sale of the Trust Securities by the Trust, the Company,
in its capacity as borrower with respect to the Debentures, shall:

      (a)   pay all costs and expenses relating to the offering, sale and
issuance of the Debentures, including commissions to the Underwriters payable
pursuant to the Underwriting Agreement and compensation of the Trustee under the
Indenture in accordance with the provisions of Section 606 of the Original
Indenture;

      (b)   be responsible for and shall pay all debts and obligations (other
than with respect to the Trust Securities) and all costs and expenses of the
Trust (including, but not limited to, costs and expenses relating to the
organization, maintenance and dissolution of the Trust, the offering, sale and
issuance of the Trust Securities (including commissions to the Underwriters in
connection therewith), the fees and expenses (including reasonable counsel fees
and expenses) of the Property Trustee, the Delaware Trustee and the
Administrative Trustees (including any amounts payable under Article 10 of the
Agreement), the costs and expenses relating to the operation of the Trust,
including without limitation, costs and expenses of accountants, attorneys,
statistical or bookkeeping services, expenses for printing and engraving and
computing or accounting equipment, paying agent(s), registrar(s), transfer
agent(s), duplicating, travel and telephone and other telecommunications
expenses and costs and expenses incurred in connection with the acquisition,
financing, and disposition of Trust assets and the enforcement by the Property
Trustee of the rights of the holders of the Trust Preferred Securities;

      (c)   pay any and all taxes (other than United States withholding taxes
attributable to the Trust or its assets) and all liabilities, costs and expenses
with respect to such taxes of the Trust; and

      (d)   be liable for any indemnification obligations arising with respect
to the Agreement.

      The Company's obligations under this Section 401 shall be for the benefit
of, and shall be enforceable by, any Person to whom such debts, obligations,
costs, expenses and taxes are owed (a "Creditor") whether or not such Creditor
has received notice hereof. Any such Creditor may enforce the Company's
obligations under this Section 401 directly against the Company and the Company
irrevocably waives any right of remedy to require that any such Creditor take
any action against the Trust or any other Person before proceeding against the
Company. The Company agrees to execute such additional agreements as may be
necessary or desirable in order to give full effect to the provisions of this
Section 401.

                                       13

<PAGE>

      The provisions of this Section shall survive the termination of this
Supplemental Indenture.

      SECTION 402. Payment Upon Resignation or Removal.

      Upon termination of this Supplemental Indenture or the Indenture or the
removal or resignation of the Trustee, unless otherwise stated, the Company
shall pay to the Trustee all amounts accrued to the date of such termination,
removal or resignation that are payable pursuant to Section 606 of the Original
Indenture. Upon termination of the Agreement or the removal or resignation of
the Delaware Trustee or the Property Trustee, as the case may be, pursuant to
Section 5.6 of the Agreement, the Company shall pay to the Delaware Trustee or
the Property Trustee, as the case may be, all amounts accrued to the date of
such termination, removal or resignation.

                                  ARTICLE FIVE

                          COVENANT TO LIST ON EXCHANGE

      SECTION 501. Listing on an Exchange.

      If the Debentures are distributed to the holders of the Trust Securities,
and the Trust Preferred Securities are then listed, the Company will use its
best efforts to list such Debentures on the NYSE or on such other exchange as
the Trust Preferred Securities are then listed.

                                  ARTICLE SIX

                           SUBORDINATION OF DEBENTURES

      SECTION 601. Debentures Subordinate to Senior Indebtedness. The Company
for itself, its successors and assigns, covenants and agrees, and each Holder of
Debentures issued, whether upon original issue or upon transfer or assignment
thereof, by its acceptance thereof likewise covenants and agrees, that the
payment of principal of and interest on each and all of the Debentures is hereby
expressly subordinated, to the extent and in the manner hereinafter in this
Article set forth, in right of payment to the prior payment in full of all
existing and future Senior Indebtedness of the Company.

      SECTION 602. Payments to Securityholders. (a) (i) In the event and during
the continuation of any default beyond any grace period in the payment of
principal of or interest on or any other monetary amounts due in respect of any
Senior Indebtedness, or in the event that any other event of default with
respect to any Senior Indebtedness shall have occurred and be continuing and
shall have resulted in such Senior Indebtedness becoming or being declared due
and payable prior to the date on which it would otherwise have become due and
payable and the Trustee has received written notice from the Company, from
holders of Senior Indebtedness or from any trustee, representative or agent
therefor, unless and until such event of default shall have been cured, waived
or remedied or shall have ceased to exist and such acceleration shall have been
rescinded or annulled or all amounts due on such Senior Indebtedness are paid in
full

                                       14

<PAGE>

in cash or other permitted consideration, or otherwise provided for, then no
payment of the principal of or interest on the Debentures shall be made by the
Company.

            (ii)  Upon any payment or distribution of assets of the Company of
      any kind or character, whether in cash, property or securities, to
      creditors upon any dissolution or winding-up or total or partial
      liquidation or reorganization of the Company, whether voluntary or
      involuntary or in bankruptcy, insolvency, receivership or other
      proceedings, all principal, premium, if any, and interest, if any, due
      upon all Senior Indebtedness shall first be paid in full, or payment
      thereof provided for in money or money's worth in accordance with its
      terms, before any payment is made on account of the principal of or
      interest on the indebtedness evidenced by the Debentures, and upon any
      such dissolution, winding-up, liquidation or reorganization, any payment
      or distribution of assets of the Company of any kind or character, whether
      in cash, property or securities, to which the Holders of the Debentures
      under the terms of this Supplemental Indenture would be entitled, except
      for the provisions hereof, shall (subject to the power of a court of
      competent jurisdiction to make other equitable provision reflecting the
      rights conferred by the provisions hereof upon the Senior Indebtedness and
      the holders thereof with respect to the Debentures and the Holders thereof
      by a lawful plan of reorganization under applicable bankruptcy law), be
      paid by the Company or any receiver, trustee in bankruptcy, liquidating
      trustee, agent or other person making such payment or distribution, or by
      the Holders of the Debentures if received by them, directly to the holders
      of Senior Indebtedness (pro rata to each such holder on the basis of the
      respective amounts of Senior Indebtedness held by such holder) or their
      representatives, to the extent necessary to pay all Senior Indebtedness
      (including interest thereon) in full, in money or money's worth, in
      accordance with its terms, after giving effect to any concurrent payment
      or distribution to or for the holders of Senior Indebtedness, before any
      payment or distribution is made to the holders of the indebtedness
      evidenced by the Debentures. The consolidation of the Company with, or a
      merger of the Company into, another Person or the liquidation or
      dissolution of the Company following the conveyance or transfer of its
      property as an entirety, or substantially as an entirety, to another
      Person upon the terms and conditions provided in Section 801 of the
      Original Indenture shall not be deemed a dissolution, winding-up,
      liquidation or reorganization for the purposes of this Section 602(a).

      (b)   In the event that any payment or distribution of assets of the
Company of any kind or character not permitted by Section 602(a), whether in
cash, property or securities, shall be received by the Trustee or the Holders of
Debentures before all Senior Indebtedness is paid in full, or provision made for
such payment, in accordance with its terms, upon written notice to the Trustee
or, as the case may be, such Holder, such payment or distribution shall be held
in trust for the benefit of, and shall be paid over or delivered to, the holders
of such Senior Indebtedness or their representative or representatives, or to
the Trustee or trustees under any indenture pursuant to which any instruments
evidencing any of such Senior Indebtedness may have been issued, as their
respective interests may appear, for application to the payment of all Senior
Indebtedness remaining unpaid to the extent necessary to pay all such Senior
Indebtedness in full in accordance with its terms, after giving effect to any
concurrent payment or distribution to the

                                       15

<PAGE>

holders of such Senior Indebtedness. Nothing in this Article shall apply to
claims of, or payments to, the Trustee under or pursuant to Section 606 of the
Original Indenture. In addition, nothing in this Article shall prevent the
Company from making or the Trustee from receiving or applying any payment in
connection with the redemption of the Debentures if the first publication of
notice of such redemption (whether by mail or otherwise in accordance with this
Supplemental Indenture) has been made, and the Trustee has received such payment
from the Company, prior to the occurrence of any of the contingencies specified
in this Section 602.

      SECTION 603. Subrogation to Rights of Holders of Senior Indebtedness. From
and after the payment in full of all Senior Indebtedness, the Holders of the
Debentures (together with the holders of any other indebtedness of the Company
which is subordinate in right of payment to the payment in full of all Senior
Indebtedness, which is not subordinate in right of payment to the Debentures and
which by its terms grants such right of subrogation to the holder thereof) shall
be subrogated to the rights of the holders of Senior Indebtedness to receive
payments or distributions of assets or securities of the Company applicable to
the Senior Indebtedness until the Debentures shall be paid in full, and, for the
purposes of such subrogation, no such payments or distributions to the holders
of Senior Indebtedness of assets or securities, which otherwise would have been
payable or distributable to Holders of the Debentures, shall, as between the
Company, its creditors (other than the holders of Senior Indebtedness), and the
Holders of the Debentures, be deemed to be a payment by the Company to or on
account of the Senior Indebtedness, it being understood that the provisions of
this Article are and are intended solely for the purpose of defining the
relative rights of the Holders of the Debentures, on the one hand, and the
holders of the Senior Indebtedness, on the other hand, and nothing contained
herein is intended to or shall impair as between the Company, its creditors
(other than the holders of Senior Indebtedness), and the Holders of the
Debentures, the obligation of the Company, which is unconditional and absolute,
to pay to the Holders of the Debentures the principal of and interest on the
Debentures as and when the same shall become due and payable in accordance with
their terms, or to affect the relative rights of the Holders of the Debentures
and creditors of the Company (other than the holders of the Senior
Indebtedness), nor shall anything herein or therein prevent the Trustee or the
Holder of Debentures from exercising all remedies otherwise permitted by
applicable law upon default hereunder with respect to the Debentures subject to
the rights of the holders of Senior Indebtedness, under Section 602, to receive
cash, property or securities of the Company otherwise payable or deliverable to
the Trustee or the Holders of the Debentures or to a representative of such
Holders, on their behalf.

      Upon any distribution or payment in connection with any proceedings or
sale referred to in Section 602(a), the Trustee and each Holder of the
Debentures then Outstanding, shall be entitled to rely upon a certificate of the
liquidating trustee or agent or other Person making any distribution or payment
to the Trustee or such Holder for the purpose of ascertaining the holders of
Senior Indebtedness entitled to participate in such payment or distribution, the
amount of such Senior Indebtedness or the amount payable thereon, the amount or
amounts paid or distributed thereon and all other facts pertinent thereto or to
this Article.

      SECTION 604. No Impairment of Subordination. Nothing contained in this
Article or elsewhere in this Supplemental Indenture or the Debentures shall
prevent at any time the

                                       16

<PAGE>

Company from making payments at any time of principal of or interest on the
Debentures, except under the conditions described in Section 602 or during the
pendency of any proceedings or sale therein referred to.

      SECTION 605. Trustee to Effectuate Subordination. Each Holder of
Debentures by his acceptance thereof, whether upon original issue or upon
transfer or assignment, authorizes and directs the Trustee on his behalf to take
such action as may be necessary or appropriate to effectuate the subordination
provisions in this Article and appoints the Trustee his attorney-in-fact for any
and all such purposes.

      No rights of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Trustee
or any Holder of the Debentures then Outstanding, or by any act or failure to
act, in good faith, by any such holder, or by any noncompliance by any such
holder, with the terms, provisions and covenants of this Supplemental Indenture,
regardless of any knowledge thereof which any such holder may have or otherwise
be charged with.

      Without in any way limiting the generality of the foregoing paragraph, the
holders of Senior Indebtedness may, at any time and from time to time, without
the consent of or notice to the Holders of the Debentures, without incurring
responsibility to the Holders of the Debentures and without impairing or
releasing the subordination provided in this Article or the obligations of the
Holders of the Debentures to the holders of Senior Indebtedness, do any one or
more of the following: (i) change the manner, place or terms of payment of, or
renew or alter, Senior Indebtedness, or otherwise amend or supplement in any
manner Senior Indebtedness or any instrument evidencing the same or any
agreement under which Senior Indebtedness is outstanding; (ii) sell, exchange,
release or otherwise deal with any property pledged, mortgaged or otherwise
securing Senior Indebtedness; (iii) release any Person liable in any manner for
the collection of Senior Indebtedness; and (iv) exercise or refrain from
exercising any rights against the Company and any other Person.

      SECTION 606. Notice to Trustee. The Company shall give prompt written
notice to the Trustee in the form of an Officers' Certificate of any fact known
to the Company which would prohibit the making of any payment of money to or by
the Trustee in respect of the Debentures pursuant to the provisions of this
Article. Notwithstanding the provisions of this Article or any other provisions
of this Supplemental Indenture, the Trustee shall not be charged with knowledge
of the existence of any facts which would prohibit the making of any payment to
or by the Trustee in respect of the Debentures pursuant to the provisions of
this Article, unless and until the Trustee shall have received at its Corporate
Trust Office written notice thereof from the Company or a holder or holders of
Senior Indebtedness or from any trustee therefor at least two Business Days
prior to such payment date; and, prior to the receipt of any such written
notice, the Trustee, shall be entitled in all respects to assume that no such
facts exist.

      The Trustee shall be entitled to rely on the delivery to it of a written
notice by a Person representing himself to be a holder of Senior Indebtedness
(or a trustee on behalf of such holder) to establish that such notice has been
given by a holder of Senior Indebtedness or a trustee on behalf of any such
holder. In the event that the Trustee determines in good faith that further

                                       17

<PAGE>

evidence is required with respect to the right of any Person as a holder of
Senior Indebtedness to participate in any payment or distribution pursuant to
this Article, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
such Person under this Article, and, if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment.

      SECTION 607. Reliance on Certificate of Liquidating Agent. Upon any
payment or distribution referred to in this Article, the Trustee and the Holders
of the Debentures shall be entitled to rely upon any order or decree entered by
any court of competent jurisdiction in which a dissolution, winding up or total
or partial liquidation or reorganization of the Company is pending, or a
certificate of the trustee in bankruptcy, liquidating trustee, custodian,
receiver, assignee for the benefit of creditors, agent or other Person making
such payment or distribution, delivered to the Trustee or to the Holders of the
Debentures, for the purpose of ascertaining the Persons entitled to participate
in such distribution, the holders of the Senior Indebtedness and other
indebtedness of the Company, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article.

      SECTION 608. Trustee Not Fiduciary for Holders of Senior Indebtedness. The
Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior
Indebtedness and shall not be liable to any such holders if it shall in good
faith mistakenly pay over or distribute to Holders of the Debentures or to the
Company or to any other Person cash, property or securities to which any holders
of Senior Indebtedness shall be entitled by virtue of this Article or otherwise.

      SECTION 609. Rights of Trustee as Holder of Senior Indebtedness. The
Trustee in its individual capacity shall be entitled to all the rights set forth
in this Article with respect to any Senior Indebtedness which may at any time be
held by it, to the same extent as any other holder of Senior Indebtedness, and
nothing in this Supplemental Indenture shall deprive the Trustee of any of its
rights as such holder.

      SECTION 610. Article Applicable to Paying Agent. In case at any time any
Paying Agent other than the Trustee shall have been appointed by the Company and
be then acting hereunder, the term "Trustee" as used in this Article shall in
such case (unless the context shall otherwise require) be construed as extending
to and including such Paying Agent within its meaning as fully for all intents
and purposes as if such Paying Agent were named in this Article in addition to
or in place of the Trustee; provided, however, that this Section shall not apply
to the Company or any Affiliate of the Company if it or such Affiliate acts as
Paying Agent.

                                 ARTICLE SEVEN

                            MISCELLANEOUS PROVISIONS

      The Trustee makes no undertaking or representations in respect of, and

                               DTE ENERGY COMPANY
                  7.50% JUNIOR SUBORDINATED DEBENTURES DUE 2044

DTE ENERGY COMPANY, a corporation duly organized and existing under the laws of
the State of Michigan (herein referred to as the "Company", which term includes
any successor Person under the Indenture hereinafter referred to), for value
received, hereby promises to pay to CEDE & CO., or registered assigns, the
principal sum of $________ on June 1, 2044 ("Stated Maturity"), unless
previously redeemed, and to pay interest at the rate of 7.50% per annum on said
principal sum from the date of issuance until the principal of this Debenture
becomes due and payable, and on any overdue principal and (to the extent that
payment of such interest is enforceable under applicable law) on any overdue
installment of interest at the same rate per annum during such overdue period.
Interest on this Debenture will be payable quarterly in arrears on March 1, June
1, September 1 and December 1 of each year (each such date, an "Interest Payment
Date"), commencing September 1, 2004.

The amount of interest payable for any period shall be computed on the basis of
twelve 30-day months and a 360-day year and, for any period shorter than a full
quarterly interest period, will be computed on the basis of the actual number of
days elapsed per 30-day month. In the event that any date on which interest is
payable on this Debenture is not a Business Day, then payment of the amount
payable on such date will be made on the next succeeding day which is a Business
Day (and without any interest or other payment in respect of any such delay),
except that, if such

                                      A-1

<PAGE>

Business Day is in the next succeeding calendar year, such payment shall be made
on the immediately preceding Business Day without reduction in the amount due to
such early payment, in each case with the same force and effect as if made on
such date. Payments of interest may be deferred by the Company pursuant to the
provisions of Article Two of the Supplemental Indenture (as defined herein) to
the Indenture (as defined herein). The interest installment so payable, and
punctually paid or duly provided for, on any Interest Payment Date with respect
to this Debenture will, as provided in the Indenture, be paid to the person in
whose name this Debenture (or one or more Predecessor Securities) is registered
at the close of business on the relevant Regular Record Date prior to the
relevant Interest Payment Date. Any such interest installment not punctually
paid or duly provided for shall forthwith cease to be payable to the registered
Holders on such Regular Record Date, and may either be paid to the person in
whose name this Debenture (or one or more Predecessor Securities) is registered
at the close of business on a Special Record Date to be fixed by the Trustee for
the payment of such defaulted interest, notice whereof shall be given to the
registered Holders of this series of Debentures not less than ten days prior to
such Special Record Date, or may be paid at any time in any other lawful manner
not inconsistent with the requirements of any securities exchange on which the
Debentures may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in the Indenture. Except as otherwise
provided in the Indenture, the principal of and the interest on this Debenture
shall be payable at the office or agency of the Company maintained for that
purpose in the Borough of Manhattan, The City of New York, in any coin or
currency of the United States of America which at the time of payment is legal
tender for payment of public and private debts; provided, however, that payment
of interest may be made at the option of the Company by check mailed to the
registered Holder at the close of business on the Regular Record Date at such
address as shall appear in the Security Register.

All references in this Debenture to interest shall include Additional Interest,
if any, and Compound Interest, if any.

This Debenture is one of a duly authorized series of Securities of the Company,
designated as the "7.50% Junior Subordinated Debentures due 2044" (the
"Debentures"), limited to an aggregate principal amount of $92,783,525 (except
for Debentures authenticated and delivered upon transfer of, or in exchange for,
or in lieu of other Debentures), all issued under and pursuant to an Amended and
Restated Indenture, dated as of April 9, 2001, as supplemented by the
Supplemental Indenture dated as of June 1, 2004, with respect to the Debentures
(the "Supplemental Indenture"), as further amended, supplemented or otherwise
modified from time to time (as so amended, supplemented or modified, the
"Indenture"), duly executed and delivered between the Company and BNY Midwest
Trust Company, an Illinois trust corporation, as Trustee (herein referred to as
the "Trustee", which term includes any successor trustee under the Indenture),
to which Indenture reference is hereby made for a description of the respective
rights, limitations of rights, obligations, duties and immunities thereunder of
the Trustee, the Company and the registered Holders of the Debentures and of the
terms upon which the Debentures are, and are to be, authenticated and delivered.

Payment of the principal of and interest on this Debenture is, to the extent
provided in the Indenture, subordinated and subject in right of payment to the
prior payment in full of all

                                      A-2

<PAGE>

existing and future Senior Indebtedness of the Company and this Debenture is
issued subject to the provisions of the Indenture with respect thereto. Each
registered Holder of this Debenture, by accepting the same, (a) agrees to and
shall be bound by such provisions, (b) authorizes and directs the Trustee on his
or her behalf to take such action as may be necessary or appropriate to
acknowledge or effectuate the subordination so provided and (c) appoints the
Trustee as his or her attorney-in-fact for any and all such purposes. Each
registered Holder hereof, by his or her acceptance hereof, hereby waives all
notice of the acceptance of the subordination provisions contained herein and in
the Indenture by each holder of Senior Indebtedness, whether now outstanding or
hereafter incurred, and waives reliance by each such Holder upon said
provisions.

The Company and, by its acceptance of this Debenture or a beneficial interest
herein, the registered Holder of, and any Person that acquires a beneficial
interest in, this Debenture agree that for United States federal, state and
local tax purposes it is intended that this Debenture constitute indebtedness,
and the Holder of, and any Person that acquires a beneficial interest in, this
Debenture agrees to treat this Debenture as indebtedness for United States
federal income tax purposes.

Notwithstanding the provisions of the Indenture, this Debenture shall be without
benefit of any security and shall be subordinated to Senior Indebtedness.

This Debenture is not subject to repayment at the option of the Holder hereof.
Except as provided below, this Debenture is not redeemable by the Company prior
to maturity and is not subject to any sinking fund.

This Debenture shall be redeemable prior to its Stated Maturity at the option of
the Company (i) in whole or in part, from time to time, on or after June 1, 2009
or (ii) at any time prior to June 1, 2009, in whole but not in part, within 90
days following the occurrence of a Special Event, in either case at a redemption
price (the "Redemption Price") equal to 100% of the principal amount thereof,
plus accrued and unpaid interest thereon (including Additional Interest and
Compound Interest, if any) to the date of redemption.

Notice of any redemption will be mailed at least 30 days but not more than 60
days before the redemption date to the Holder hereof at its registered address.
Unless the Company defaults in payment of the Redemption Price, on and after the
redemption date interest will cease to accrue on the principal amount of this
Debenture called for redemption.

If money sufficient to pay the Redemption Price with respect to the principal
amount of and accrued interest on the principal amount of this Debenture to be
redeemed on the redemption date is deposited with the Trustee on or before the
redemption date and certain other conditions are satisfied, then on or after
such date, interest will cease to accrue on the principal amount of this
Debenture called for redemption.

If the Debentures are only partially redeemed by the Company, the Debentures
will be redeemed pro rata or by lot or by any other method utilized by the
Trustee; provided that if, at the time of redemption, the Debentures are
registered as a Global Debenture, the Depositary shall determine by lot the
principal amount of such Debentures held by each Debenture Holder to be
redeemed.

                                      A-3

<PAGE>

In the event of redemption of this Debenture in part only, a new Debenture or
Debentures of this series for the unredeemed portion hereof will be issued in
the name of the registered Holder hereof upon the cancellation hereof.

In case an Event of Default, as defined in the Indenture, shall have occurred
and be continuing, the principal hereof may be declared, and upon such
declaration shall become, due and payable, in the manner, with the effect and
subject to the conditions provided in the Indenture.

The provisions relating to defeasance and covenant defeasance in the Indenture
in Section 403 thereof shall not apply to this Debenture.

The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Debentures under the Indenture at
any time by the Company and the Trustee with the consent of the Holders of a
majority of the aggregate principal amount of all Debentures issued under the
Indenture at the time outstanding and affected thereby; provided, however, that
no such amendment shall without the consent of the Holder of each Debenture so
affected, among other things (i) change the stated maturity of the principal of,
or any installment of principal of or interest on any Debentures of any series,
or reduce the principal amount thereof, or reduce the rate of interest thereon,
or reduce any premium payable upon the redemption thereof, (ii) reduce the
aforesaid percentage of the Holders of which are required to consent to any such
supplemental indenture or (iii) modify any of the subordination provisions
contained herein in a manner adverse to the Holder hereof. The Indenture also
contains provisions permitting (i) the registered Holders of at least 66 2/3% in
aggregate principal amount of the Securities of all series at the time
outstanding affected thereby, on behalf of the registered Holders of the
Securities of such series, to waive compliance by the Company with certain
provisions of the Indenture and (ii) the registered Holders of not less than a
majority in aggregate principal amount of the Securities of any series at the
time outstanding affected thereby, on behalf of the registered Holders of the
Securities of such series, to waive certain past defaults under the Indenture
and their consequences. Any such consent or waiver by the registered Holder of
this Debenture (unless revoked as provided in the Indenture) shall be conclusive
and binding upon such registered Holder and upon all future registered Holders
and owners of this Debenture and of any Debenture issued in exchange hereof or
in place hereof (whether by registration of transfer or otherwise), irrespective
of whether or not any notation of such consent or waiver is made upon this
Debenture.

No reference herein to the Indenture and no provision of this Debenture or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and interest on this
Debenture at the time and place and at the rate and in the coin or currency
herein prescribed.

As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Debenture is registrable in the Security Register of
the Company, upon surrender of this Debenture for registration of transfer at
the office or agency of the Company in any place where the principal of and any
interest on this Debenture are payable or at such other offices or

                                      A-4

<PAGE>

agencies as the Company may designate, duly endorsed by or accompanied by a
written instrument or instruments of transfer in form satisfactory to the
Company and the Security Registrar or any transfer agent duly executed by the
registered Holder hereof or his or her attorney duly authorized in writing, and
thereupon one or more new Debentures of this series and of like tenor, of
authorized denominations and for the same aggregate principal amount will be
issued to the designated transferee or transferees. No service charge will be
made for any such transfer, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in relation
thereto.

Prior to due presentment for registration of transfer of this Debenture, the
Company, the Trustee, any Paying Agent and any Security Registrar may deem and
treat the registered Holder hereof as the absolute owner hereof (whether or not
this Debenture shall be overdue and notwithstanding any notice of ownership or
writing hereon made by anyone other than the Security Registrar) for the purpose
of receiving payment of or on account of the principal hereof and interest due
hereon and for all other purposes, and neither the Company nor the Trustee nor
any paying agent nor any Security Registrar shall be affected by any notice to
the contrary.

The Debentures of this series are issuable only in fully registered form without
coupons in denominations of $25 and any integral multiple thereof. This Global
Debenture is exchangeable for Debentures in definitive form only under certain
limited circumstances set forth in the Indenture. Debentures of this series so
issued are issuable only in registered form without coupons in denominations of
$25 and any integral multiple thereof. As provided in the Indenture and subject
to certain limitations therein set forth, Debentures of this series are
exchangeable for a like aggregate principal amount of Debentures of this series
of a different authorized denomination, as requested by the registered Holder
surrendering the same.

As set forth in, and subject to the provisions of, the Indenture, no registered
owner of any Debenture will have any right to institute any proceeding with
respect to the Indenture or for any remedy thereunder, unless (i) such
registered owner shall have previously given to the Trustee written notice of a
continuing Event of Default with respect to the Debentures of this series, (ii)
the registered owners of not less than 25% in principal amount of the
Outstanding Debentures of this series shall have made written request, and
offered reasonable indemnity, to the Trustee to institute such proceeding as
trustee, (iii) the Trustee shall have failed to institute such proceeding within
60 days and (iv) the Trustee shall not have received from the registered owners
of a majority in principal amount of the outstanding Debentures of this series a
direction inconsistent with such request within such 60-day period; provided,
however, that such limitations do not apply to a suit instituted by the
registered owner hereof for the enforcement of payment of the principal of or
any interest on this Debenture on or after the respective due dates expressed
herein.

Unless the Certificate of Authentication hereon has been executed by the Trustee
or a duly appointed Authentication Agent referred to herein, this Debenture
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

Borrowing shall be made on notice, given not later than 11:00 A.M. (New York
City time) on the third Business Day prior to the date of the proposed Borrowing
in the case of a Borrowing consisting of Eurodollar Rate Advances, or 10:00 A.M.
(New York City time) on the Business Day of the proposed Borrowing in the case
of a Borrowing consisting of Base Rate Advances, by the Borrower to the Agent,
which shall give to each Lender prompt notice thereof by telecopier or telex.
Each such notice of a Borrowing (a "Notice of Borrowing") shall be by telephone,
confirmed immediately in writing, telecopier or telex in substantially the form
of Exhibit B hereto, specifying therein the requested (i) date of such
Borrowing, (ii) Type of Revolving Credit Advances comprising such Borrowing,

Revolving Credit Advance. Each Lender shall, before 12:00 noon (New York City
time) on the date of such Borrowing, make available for the account of its
Applicable Lending Office to the Agent at the Agent's Account, in same day
funds, such Lender's ratable portion of such Borrowing. After the Agent's

at the Agent's address referred to in Section 8.02.

      (b) Anything in subsection (a) above to the contrary notwithstanding, (i)
the Borrower may not select Eurodollar Rate Advances for any Borrowing if the
aggregate amount of such Borrowing is less than $5,000,000 or if the obligation
of the Lenders to make Eurodollar Rate Advances shall then be suspended pursuant
to Section 2.07 or 2.11 and (ii) at no time shall the sum of all Borrowings
comprising Eurodollar Rate Advances outstanding hereunder be greater than ten.

indemnify each Lender against any loss, cost or expense incurred by such Lender
as a result of any failure to fulfill on or before the date specified in such
Notice of Borrowing for such Borrowing the applicable conditions set forth in

anticipated profits), cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by such Lender to fund the
Revolving Credit Advance to be made by such Lender as part of such Borrowing
when such Revolving Credit Advance, as a result of such failure, is not made on
such date.

      (d) Unless the Agent shall have received notice from a Lender prior to the
date of any Borrowing that such Lender will not make available to the Agent such
Lender's ratable portion of such Borrowing, the Agent may assume that such
Lender has made such portion available to the Agent on the date of such
Borrowing in accordance with subsection (a) of this Section 2.02 and the Agent
may, in reliance upon such assumption, make available to the Borrower on such
date a corresponding amount. If and to the extent that such Lender shall not
have so made such

                                       14

Revolving Credit Advances comprising such Borrowing and (ii) in the case of such
Lender, the Federal Funds Rate. If such Lender shall repay to the Agent such
corresponding amount, such amount so repaid shall constitute such Lender's
Revolving Credit Advance as part of such Borrowing for purposes of this
Agreement.

      (e) The failure of any Lender to make the Revolving Credit Advance to be
made by it as part of any Borrowing shall not relieve any other Lender of its
obligation, if any, hereunder to make its Revolving Credit Advance on the date
of such Borrowing, but no Lender shall be responsible for the failure of any
other Lender to make the Revolving Credit Advance to be made by such other
Lender on the date of any Borrowing.

Aggregate Outstanding Credit Exposures hereunder exceeds thirty-three percent
(33%) of the aggregate amount of all Commitments hereunder then in effect on

amount of all Commitments in effect immediately prior to such termination), the
Borrower will pay to the Agent for the ratable benefit of the Lenders a
utilization fee (the "Utilization Fee") at a per annum rate equal to the

multiple of $1,000,000 in excess thereof. Once terminated, a Commitment or
portion thereof may not be reinstated.

Termination Date the Aggregate Outstanding Credit Exposures and all other unpaid
Obligations.

            SECTION 2.06. Interest on Revolving Credit Advances. (a) Scheduled
Interest. The Borrower shall pay interest on the unpaid principal amount of each
Revolving Credit Advance owing to each Lender from the date of such Revolving
Credit Advance until such principal amount shall be paid in full, at the
following rates per annum:

            (i) Base Rate Advances. During such periods as such Revolving Credit
      Advance is a Base Rate Advance, a rate per annum equal at all times to the
      sum of (x) the Base Rate in effect from time to time plus (y) the
      Applicable Margin in effect from time to time, payable in arrears
      quarterly on the last day of each March, June, September and December
      during such periods and on the date such Base Rate Advance shall be
      Converted or paid in full.

            (ii) Eurodollar Rate Advances. During such periods as such Revolving
      Credit Advance is a Eurodollar Rate Advance, a rate per annum equal at all
      times during each Interest Period for such Revolving Credit Advance to the
      sum of (x) the Eurodollar Rate for such Interest Period for such Revolving
      Credit Advance plus (y) the Applicable Margin in effect from time to time,
      payable in arrears on the last day of such Interest Period and, if such
      Interest Period has a duration of more than three months, on each day that
      occurs during such Interest Period every three months from the first day
      of such Interest Period and on the date such Eurodollar Rate Advance shall
      be Converted or paid in full.

            (b) Default Interest. (i) Upon the occurrence and during the
continuance of an Event of Default, (x) the Borrower shall pay interest on the
unpaid principal amount of each Revolving Credit Advance owing to each Lender,
payable in arrears on the dates referred to in clause (a)(i) or (a)(ii) above,
at a rate per annum equal at all times to 2% per annum above the rate per annum
required to be paid on such Revolving Credit Advance pursuant to clause (a)(i)
or (a)(ii) above and (y) the LC Fee shall be increased by 2% per annum, and (ii)
the Borrower shall pay, to the fullest extent permitted by law, the amount of
any interest, fee or other amount payable hereunder that is not paid when due,
from the date such amount shall be due until such

                                       16
<PAGE>

amount shall be paid in full, payable in arrears on the date such amount shall
be paid in full and on demand, at a rate per annum equal at all times to 2% per
annum above the rate per annum required to be paid on Base Rate Advances
pursuant to clause (a)(i) above.

            SECTION 2.07. Interest Rate Determination. (a) Each Reference Bank
agrees to furnish to the Agent timely information for the purpose of determining
each Eurodollar Rate. If any one or more of the Reference Banks shall not
furnish such timely information to the Agent for the purpose of determining any
such interest rate, the Agent shall determine such interest rate on the basis of
timely information furnished by the remaining Reference Banks. The Agent shall
give prompt notice to the Borrower and the Lenders of the applicable interest
rate determined by the Agent for purposes of Section 2.06(a)(i) or (ii), and the
rate, if any, furnished by each Reference Bank for the purpose of determining
the interest rate under Section 2.06(a)(ii).

            (b) If, with respect to any Eurodollar Rate Advances, the Required
Lenders notify the Agent that the Eurodollar Rate for any Interest Period for
such Eurodollar Rate Advances will not adequately reflect the cost to such
Required Lenders of making, funding or maintaining their respective Eurodollar
Rate Advances for such Interest Period, the Agent shall forthwith so notify the
Borrower and the Lenders, whereupon (i) each Eurodollar Rate Advance will
automatically, on the last day of the then existing Interest Period therefor,
Convert into a Base Rate Advance, and (ii) the obligation of the Lenders to
make, or to Convert Revolving Credit Advances into, Eurodollar Rate Advances
shall be suspended until the Agent shall notify the Borrower and the Lenders
that the circumstances causing such suspension no longer exist.

            (c) If the Borrower shall fail to select the duration of any
Interest Period for any Eurodollar Rate Advances in accordance with the
provisions contained in the definition of "Interest Period" in Section 1.01, the
Agent will forthwith so notify the Borrower and the Lenders and such Eurodollar
Rate Advances will automatically, on the last day of the then existing Interest
Period therefor, Convert into Base Rate Advances.

            (d) On the date on which the aggregate unpaid principal amount of
Eurodollar Rate Advances comprising any Borrowing shall be reduced, by payment
or prepayment or otherwise, to less than $5,000,000, such Eurodollar Rate
Advances shall automatically Convert into Base Rate Advances.

            (e) Upon the occurrence and during the continuance of any Event of
Default, (i) each Eurodollar Rate Advance will automatically, on the last day of
the then existing Interest Period therefor, Convert into a Base Rate Advance and
(ii) the obligation of the Lenders to make, or to Convert Revolving Credit
Advances into, Eurodollar Rate Advances shall be suspended.

            (f) If fewer than two Reference Banks furnish timely information to
the Agent for determining the Eurodollar Rate for any Eurodollar Rate Advances:

            (i) the Agent shall forthwith notify the Borrower and the Lenders
      that the interest rate cannot be determined for such Eurodollar Rate
      Advances,

                                       17
<PAGE>

            (ii) with respect to Eurodollar Rate Advances, each such Eurodollar
      Rate Advance will automatically, on the last day of the then existing
      Interest Period therefor, Convert into a Base Rate Advance (or if such
      Eurodollar Rate Advance is then a Base Rate Advance, will continue as a
      Base Rate Advance), and

            (iii) the obligation of the Lenders to make Eurodollar Rate Advances
      or to Convert Revolving Credit Advances into Eurodollar Rate Advances
      shall be suspended until the Agent shall notify the Borrower and the
      Lenders that the circumstances causing such suspension no longer exist.

            SECTION 2.08. Optional Conversion of Revolving Credit Advances. The
Borrower may on any Business Day, upon notice given to the Agent not later than
11:00 A.M. (New York City time) on the third Business Day prior to the date of
the proposed Conversion and subject to the provisions of Sections 2.07 and 2.11,
Convert all Revolving Credit Advances of one Type comprising the same Borrowing
into Revolving Credit Advances of the other Type (it being understood that such
Conversion of a Revolving Credit Advance or of its Interest Period does not
constitute a repayment or prepayment of such Revolving Credit Advance);
provided, however, that any Conversion of Eurodollar Rate Advances into Base
Rate Advances shall be made only on the last day of an Interest Period for such
Eurodollar Rate Advances, any Conversion of Base Rate Advances into Eurodollar
Rate Advances shall be in an amount not less than the minimum amount specified
in Section 2.02(b) and no Conversion of any Revolving Credit Advances shall
result in more separate Borrowings than permitted under Section 2.02(b). Each
such notice of a Conversion shall, within the restrictions specified above,
specify (i) the date of such Conversion, (ii) the Revolving Credit Advances to
be Converted, and (iii) if such Conversion is into Eurodollar Rate Advances, the
duration of the initial Interest Period for each such Eurodollar Rate Advance.
Each notice of Conversion shall be irrevocable and binding on the Borrower.

            SECTION 2.09. Prepayments of Revolving Credit Advances. (a) Optional
Prepayment. The Borrower may on any Business Day, upon notice given to the Agent
not later than 11:00 A.M. (New York City time), (i) on the same day for Base
Rate Advances and (ii) on the second Business Day prior to the prepayment in the
case of Eurodollar Rate Advances stating the proposed date and aggregate
principal amount of the prepayment (and if such notice is given the Borrower
shall) prepay the outstanding principal amount of the Revolving Credit Advances
comprising part of the same Borrowing in whole or ratably in part, together with
accrued interest to the date of such prepayment on the principal amount prepaid;
provided, however, that (x) each partial prepayment shall be in an aggregate
principal amount of $5,000,000 or an integral multiple of $1,000,000 in excess
thereof and (y) in the event of any such prepayment of a Eurodollar Rate
Advance, the Borrower shall be obligated to reimburse the Lenders in respect
thereof pursuant to Section 8.04(c).

            (b) Mandatory Prepayment. The Borrower shall, upon five Business
Days notice from the Agent given at the request or with the consent of the
Required Lenders, prepay the Aggregate Outstanding Credit Exposures plus all
interest thereon and all other amounts payable hereunder or under the Notes, in
the event that: (i) any Person or two or more Persons acting in concert shall
have acquired beneficial ownership (within the meaning of Rule 13d-3 of

                                       18
<PAGE>

the Securities and Exchange Commission under the Securities Exchange Act of
1934), directly or indirectly, of Voting Stock of the Borrower (or other
securities convertible into such Voting Stock) representing 20% or more of the
combined voting power of all Voting Stock of the Borrower; or (ii) any Person or
two or more Persons acting in concert shall have acquired by contract or
otherwise, or shall have entered into a contract or arrangement that, upon
consummation, will result in its or their acquisition of the power to exercise,
directly or indirectly, a controlling influence over the management or policies
of the Borrower.

            SECTION 2.10. Increased Costs. (a) If, due to either (i) the
introduction of or any change in or in the interpretation of any law or
regulation or (ii) the compliance with any guideline or request from any central
bank or other governmental authority (whether or not having the force of law),
there shall be any increase in the cost to any Lender of agreeing to make or
making, funding or maintaining Eurodollar Rate Advances (excluding for purposes
of this Section 2.10 any such increased costs resulting from (i) Taxes or Other
Taxes (as to which Section 2.13 shall govern) or participating in any Facility
LC or to any LC Issuer of agreeing to issue any Facility LC hereunder and (ii)
changes in the basis of taxation of overall net income or overall gross income
by the United States or by the foreign jurisdiction or state under the laws of
which such Lender or such LC Issuer is organized or has its Applicable Lending
Office or any political subdivision thereof), then the Borrower shall from time
to time, upon demand by such Lender or such LC Issuer (with a copy of such
demand to the Agent), pay to the Agent for the account of such Lender or such LC
Issuer, as applicable, additional amounts sufficient to compensate such Lender
or such LC Issuer, as applicable, for such increased cost. A certificate as to
the amount of such increased cost, submitted to the Borrower and the Agent by
such Lender or such LC Issuer, as applicable, shall be conclusive and binding
for all purposes, absent manifest error.

            (b) If any Lender or LC Issuer determines that compliance with any
law or regulation or any guideline or request from any central bank or other
governmental authority (whether or not having the force of law) affects or would
affect the amount of capital required or expected to be maintained by such
Lender or such LC Issuer or any corporation controlling such Lender or such LC
Issuer, as applicable, and that the amount of such capital is increased by or
based upon the existence of such Lender's commitment to lend hereunder or to
participate in Facility LCs hereunder and other commitments of this type or such
LC Issuer's issuance of Facility LCs hereunder, then, upon demand by such Lender
or such LC Issuer, as applicable, (with a copy of such demand to the Agent), the
Borrower shall pay to the Agent for the account of such Lender or such LC
Issuer, as applicable, from time to time as specified by such Lender or such LC
Issuer, as applicable, additional amounts sufficient to compensate such Lender
or such LC Issuer, as applicable, or such corporation in the light of such
circumstances, to the extent that such Lender or such LC Issuer, as applicable,
reasonably determines such increase in capital to be allocable to the existence
of such Lender's commitment to lend hereunder or to participate in Facility LCs
hereunder or such LC Issuer's issuance of Facility LCs hereunder. A certificate
as to such amounts submitted to the Borrower and the Agent by such Lender or
such LC Issuer, as applicable, shall be conclusive and binding for all purposes,
absent manifest error.

            (c) In the event that a Lender demands payment from the Borrower for
amounts owing pursuant to subsection (a) or (b) of this Section 2.10, the
Borrower may, upon

                                       19
<PAGE>

payment of such amounts and subject to the requirements of Sections 8.04 and
8.07, substitute for such Lender another financial institution, which financial
institution shall be an Eligible Assignee and shall assume the Commitments of
such Lender and purchase the Outstanding Credit Exposures held by such Lender in
accordance with Section 8.07, provided, however, that (i) no Default shall have
occurred and be continuing, (ii) the Borrower shall have satisfied all of its
obligations in connection with the Loan Documents with respect to such Lender,
and (iii) if such assignee is not a Lender, (A) such assignee is acceptable to
the Agent and (B) the Borrower shall have paid the Agent a $3,000 administrative
fee.

            SECTION 2.11. Illegality. Notwithstanding any other provision of
this Agreement, if any Lender shall notify the Agent that the introduction of or
any change in or in the interpretation of any law or regulation makes it
unlawful, or any central bank or other governmental authority asserts that it is
unlawful, for any Lender or its Eurodollar Lending Office to perform its
obligations hereunder to make Eurodollar Rate Advances or to fund or maintain
Eurodollar Rate Advances hereunder, (i) each Eurodollar Rate Advance will
automatically, upon such demand, Convert into a Base Rate Advance or a Revolving
Credit Advance that bears interest at the rate set forth in Section 2.06(a)(i),
as the case may be, and (ii) the obligation of the Lenders to make Eurodollar
Rate Advances or to Convert Revolving Credit Advances into Eurodollar Rate
Advances shall be suspended until the Agent shall notify the Borrower and the
Lenders that the circumstances causing such suspension no longer exist.

            SECTION 2.12. Payments and Computations. (a) The Borrower shall make
each payment hereunder and under the Notes not later than 11:00 A.M. (New York
City time) on the day when due in U.S. dollars to the Agent at the Agent's
Account in same day funds and without set off, deduction or counterclaim. The
Agent will promptly thereafter cause to be distributed like funds relating to
the payment of principal or interest, facility fees or the Utilization Fee
ratably (other than amounts payable pursuant to Section 2.10, 2.13 or 8.04(c))
to the Lenders and the LC Issuers, as applicable, for the account of their
respective Applicable Lending Offices, and like funds relating to the payment of
any other amount payable to any Lender or LC Issuer to such Lender or LC Issuer
for the account of its Applicable Lending Office, in each case to be applied in
accordance with the terms of this Agreement. Upon its acceptance of an
Assignment and Acceptance and recording of the information contained therein in
the Register pursuant to Section 8.07(c), from and after the effective date
specified in such Assignment and Acceptance, the Agent shall make all payments
hereunder and under the Notes in respect of the interest assigned thereby to the
Lender assignee thereunder, and the parties to such Assignment and Acceptance
shall make all appropriate adjustments in such payments for periods prior to
such effective date directly between themselves.

            (b) The Borrower hereby authorizes each Lender and each LC Issuer,
if and to the extent payment owed to such Lender or LC Issuer is not made when
due hereunder or under the Note held by such Lender or LC Issuer, to charge from
time to time against any or all of the Borrower's accounts with such Lender or
LC Issuer any amount so due.

            (c) All computations of interest based on the Base Rate shall be
made by the Agent on the basis of a year of 365 or 366 days, as the case may be,
and all computations of interest based on the Eurodollar Rate or the Federal
Funds Rate and of facility fees, the LC Fee

                                       20
<PAGE>

and the Utilization Fee shall be made by the Agent on the basis of a year of 360
days, in each case for the actual number of days (including the first day but
excluding the last day) occurring in the period for which such interest,
facility fees, the LC Fee or Utilization Fee are payable. Each determination by
the Agent of an interest rate hereunder shall be conclusive and binding for all
purposes, absent manifest error.

            (d) Whenever any payment hereunder or under the Notes shall be
stated to be due on a day other than a Business Day, such payment shall be made
on the next succeeding Business Day, and such extension of time shall in such
case be included in the computation of payment of interest, facility fee, the LC
Fee or the Utilization Fee, as the case may be; provided, however, that, if such
extension would cause payment of interest on or principal of Eurodollar Rate
Advances to be made in the next following calendar month, such payment shall be
made on the next preceding Business Day.

            (e) Unless the Agent shall have received notice from the Borrower
prior to the date on which any payment is due to the Lenders hereunder that the
Borrower will not make such payment in full, the Agent may assume that the
Borrower has made such payment in full to the Agent on such date and the Agent
may, in reliance upon such assumption, cause to be distributed to each Lender on
such due date an amount equal to the amount then due such Lender. If and to the
extent the Borrower shall not have so made such payment in full to the Agent,
each Lender shall repay to the Agent forthwith on demand such amount distributed
to such Lender together with interest thereon, for each day from the date such
amount is distributed to such Lender until the date such Lender repays such
amount to the Agent, at the Federal Funds Rate.

            SECTION 2.13. Taxes. (a) Any and all payments by the Borrower
hereunder or under the Notes shall be made, in accordance with Section 2.12,
free and clear of and without deduction for any and all present or future taxes,
levies, imposts, deductions, charges or withholdings, and all liabilities with
respect thereto, excluding, in the case of each Lender. each LC Issuer and the
Agent, taxes imposed on its overall net income, and franchise taxes imposed on
it in lieu of net income taxes, by the jurisdiction under the laws of which such
Lender, such LC Issuer or the Agent (as the case may be) is organized or any
political subdivision thereof and, in the case of each Lender, taxes imposed on
its overall net income, and franchise taxes imposed on it in lieu of net income
taxes, by the jurisdiction of such Lender's or such LC Issuer's Applicable
Lending Office or any political subdivision thereof (all such non-excluded
taxes, levies, imposts, deductions, charges, withholdings and liabilities in
respect of payments hereunder or under the Notes being hereinafter referred to
as "Taxes"). If the Borrower shall be required by law to deduct any Taxes from
or in respect of any sum payable hereunder or under any Note to any Lender, any
LC Issuer or the Agent, (i) the sum payable shall be increased as may be
necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section 2.13) such Lender, such
LC Issuer or the Agent (as the case may be) receives an amount equal to the sum
it would have received had no such deductions been made, (ii) the Borrower shall
make such deductions and (iii) the Borrower shall pay the full amount deducted
to the relevant taxation authority or other authority in accordance with
applicable law.

                                       21
<PAGE>

            (b) In addition, the Borrower agrees to pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies that arise from any payment made hereunder or under the Notes or
from the execution, delivery or registration of, performing under, or otherwise
with respect to, this Agreement or the Notes (hereinafter referred to as "Other
Taxes").

            (c) The Borrower shall indemnify each Lender, each LC Issuer and the
Agent for the full amount of Taxes or Other Taxes (including, without
limitation, any taxes imposed by any jurisdiction on amounts payable under this
Section 2.13) imposed on or paid by such Lender or the Agent (as the case may
be) and any liability (including penalties, interest and expenses) arising
therefrom or with respect thereto. This indemnification shall be made within 30
days from the date such Lender, such LC Issuer or the Agent (as the case may be)
makes written demand therefor.

            (d) Within 30 days after the date of any payment of Taxes, the
Borrower shall furnish to the Agent, at its address referred to in Section 8.02,
the original or a certified copy of a receipt evidencing payment thereof. In the
case of any payment hereunder or under the Notes by or on behalf of the Borrower
through an account or branch outside the United States or by or on behalf of the
Borrower by a payor that is not a United States person, if the Borrower
determines that no Taxes are payable in respect thereof, the Borrower shall
furnish, or shall cause such payor to furnish, to the Agent, at such address, an
opinion of counsel acceptable to the Agent stating that such payment is exempt
from Taxes. For purposes of this subsection (d) and subsection (e), the terms
"United States" and "United States person" shall have the meanings specified in
Section 7701 of the Internal Revenue Code.

            (e) Each Lender organized under the laws of a jurisdiction outside
the United States, on or prior to the date of its execution and delivery of this
Agreement in the case of each Initial Lender and on the date of the Assignment
and Acceptance pursuant to which it becomes a Lender in the case of each other
Lender, and from time to time thereafter as requested in writing by the Borrower
(but only so long as such Lender remains lawfully able to do so), shall provide
each of the Agent and the Borrower with two original Internal Revenue Service
Form W-8BEN or W-8ECI, as appropriate, or any successor or other form prescribed
by the Internal Revenue Service, certifying that such Lender is exempt from or
entitled to a reduced rate of United States withholding tax on payments pursuant
to this Agreement or the Notes. If the forms provided by a Lender at the time
such Lender first becomes a party to this Agreement indicates a United States
interest withholding tax rate in excess of zero, withholding tax at such rate
shall be considered excluded from Taxes unless and until such Lender provides
the appropriate forms certifying that a lesser rate applies, whereupon
withholding tax at such lesser rate only shall be considered excluded from Taxes
for periods governed by such form; provided, however, that, if at the date of
the Assignment and Acceptance pursuant to which a Lender assignee becomes a
party to this Agreement, the Lender assignor was entitled to payments under
subsection (a) in respect of United States withholding tax with respect to
interest paid at such date, then, to such extent, the term Taxes shall include
(in addition to withholding taxes that may be imposed in the future or other
amounts otherwise includable in Taxes) United States withholding tax, if any,
applicable with respect to the Lender assignee on such date. If any form or
document referred to in this subsection (e) requires the disclosure of
information, other than information necessary to

                                       22
<PAGE>

compute the tax payable and information required on the date hereof by Internal
Revenue Service Form W-8BEN or W-8ECI, that the Lender reasonably considers to
be confidential, the Lender shall give notice thereof to the Borrower and shall
not be obligated to include in such form or document such confidential
information.

            (f) For any period with respect to which a Lender has failed to
provide the Borrower with the appropriate form described in Section 2.13(e)
(other than if such failure is due to a change in law occurring subsequent to
the date on which a form originally was required to be provided, or if such form
otherwise is not required under the first sentence of subsection (e) above),
such Lender shall not be entitled to indemnification under Section 2.13(a) or
(c) with respect to Taxes imposed by the United States by reason of such
failure; provided, however, that should a Lender become subject to Taxes because
of its failure to deliver a form required hereunder, the Borrower shall take
such steps as the Lender shall reasonably request to assist the Lender to
recover such Taxes.

            (g) In the event that a Lender demands payment from the Borrower for
amounts owing pursuant to subsection (a) or (b) of this Section 2.13, the
Borrower may, upon payment of such amounts and subject to the requirements of
Sections 8.04 and 8.07, substitute for such Lender another financial
institution, which financial institution shall be an Eligible Assignee and shall
assume the Commitments of such Lender and purchase the Outstanding Credit
Exposures held by such Lender in accordance with Section 8.07, provided,
however, that (i) no Default shall have occurred and be continuing, (ii) the
Borrower shall have satisfied all of its obligations in connection with the Loan
Documents with respect to such Lender, and (iii) if such assignee is not a
Lender, (A) such assignee is acceptable to the Agent and (B) the Borrower shall
have paid the Agent a $3,000 administrative fee.

            SECTION 2.14. Sharing of Payments, Etc. If any Lender shall obtain
any payment (whether voluntary, involuntary, through the exercise of any right
of set-off, or otherwise) on account of the Outstanding Credit Exposures owing
to it (other than pursuant to Section 2.10, 2.13 or 8.04(c)) in excess of its
ratable share of payments on account of the Outstanding Credit Exposures
obtained by all the Lenders, such Lender shall forthwith purchase from the other
Lenders such participations in the Aggregate Outstanding Credit Exposures owing
to them as shall be necessary to cause such purchasing Lender to share the
excess payment ratably with each of them; provided, however, that if all or any
portion of such excess payment is thereafter recovered from such purchasing
Lender, such purchase from each Lender shall be rescinded and such Lender shall
repay to the purchasing Lender the purchase price to the extent of such recovery
together with an amount equal to such Lender's ratable share (according to the
proportion of (i) the amount of such Lender's required repayment to (ii) the
total amount so recovered from the purchasing Lender) of any interest or other
amount paid or payable by the purchasing Lender in respect of the total amount
so recovered. The Borrower agrees that any Lender so purchasing a participation
from another Lender pursuant to this Section 2.14 may, to the fullest extent
permitted by law, exercise all its rights of payment (including the right of
set-off) with respect to such participation as fully as if such Lender were the
direct creditor of the Borrower in the amount of such participation.

                                       23
<PAGE>

            SECTION 2.15. Use of Proceeds. The proceeds of the Revolving Credit
Advances shall be available and Facility LCs shall be issued hereunder (and the
Borrower agrees that it shall use such proceeds and Facility LCs) solely for
general corporate purposes, including commercial paper liquidity, of the
Borrower and its Subsidiaries.

            SECTION 2.16. Facility LCs. (a) Issuance. Each LC Issuer hereby
agrees, on the terms and conditions set forth in this Agreement, to issue
standby letters of credit (each, a "Facility LC") and to renew, extend,
increase, decrease or otherwise modify each Facility LC ("Modify", and each such
action a "Modification"), from time to time from and including the date of this
Agreement and prior to the Revolver Termination Date upon the request of the
Borrower; provided that immediately after each such Facility LC is issued or
Modified, (i) the aggregate amount of the outstanding LC Obligations shall not
exceed $375,000,000 and (ii) the Aggregate Outstanding Credit Exposures shall
not exceed the aggregate of all the Commitments. No Facility LC shall have an
expiry date later than the earlier of (x) the fifth Business Day prior to the
Revolver Termination Date and (y) one year after its issuance; provided that any
Facility LC with a one-year term may provide for the renewal thereof for
additional one-year periods (which shall in no event extend beyond the date
referenced in clause (x) above). Subject to the terms and conditions hereof
(other than the notice required pursuant to Section 2.16(c) below, which shall
be deemed satisfied by the attached Schedule II), from and after the Effective
Date, each of the letters of credit identified in Schedule II hereto and issued
for the account of the Borrower shall be deemed to be Facility LCs issued
pursuant to this Agreement, and any reference in this Agreement to the
"issuance" of a Facility LC (or "issue" or other references to forms of such
verb in this context) shall include the deemed issuance provided hereby.

            (b) Participations. Upon the issuance or Modification by any LC
Issuer of a Facility LC in accordance with this Section 2.16 (including, from
and after the Effective Date, each of the letters of credit identified in
Schedule II and deemed to be Facility LCs issued pursuant to this Agreement),
any LC Issuer shall be deemed, without further action by any party hereto, to
have unconditionally and irrevocably sold to each Lender, and each Lender shall
be deemed, without further action by any party hereto, to have unconditionally
and irrevocably purchased from any LC Issuer, a participation in such Facility
LC (and each Modification thereof) and the related LC Obligations in proportion
to its Pro Rata Share.

            (c) Notice. Subject to Section 2.16(a), the Borrower shall give any
LC Issuer notice prior to 11:00 a.m. (New York City time) at least five Business
Days prior to the proposed date of issuance or Modification of each Facility LC,
specifying the beneficiary, the proposed date of issuance (or Modification) and
the expiry date of such Facility LC, and describing the proposed terms of such
Facility LC and the nature of the transactions proposed to be supported thereby.
Upon receipt of such notice, any LC Issuer shall promptly notify the Agent, and
the Agent shall promptly notify each Lender, of the contents thereof and of the
amount of such Lender's participation in such proposed Facility LC. The issuance
or Modification by the LC Issuer of any Facility LC shall, in addition to the
conditions precedent set forth in Article III (the satisfaction of which the LC
Issuer shall have no duty to ascertain), be subject to the conditions precedent
that such Facility LC shall be satisfactory to the LC Issuer and that the
Borrower shall have executed and delivered such application agreement and/or
such other instruments and agreements relating to such Facility LC as the LC
Issuer shall have reasonably requested (each, a

                                       24
<PAGE>

"Facility LC Application"). In the event of any conflict between the terms of
this Agreement and the terms of any Facility LC Application, the terms of this
Agreement shall control.

            (d) Administration; Reimbursement by Lenders. Upon receipt from the
beneficiary of any Facility LC of any demand for payment under such Facility LC,
the LC Issuer shall notify the Agent and the Agent shall promptly notify the
Borrower and each other Lender as to the amount to be paid by any LC Issuer as a
result of such demand and the proposed payment date (the "LC Payment Date"). The
responsibility of the LC Issuer to the Borrower and each Lender shall be only to
determine that the documents (including each demand for payment) delivered under
each Facility LC in connection with such presentment shall be in conformity in
all material respects with such Facility LC. The LC Issuer shall endeavor to
exercise the same care in the issuance and administration of the Facility LCs as
it does with respect to letters of credit in which no participations are
granted, it being understood that in the absence of any gross negligence or
willful misconduct by the LC Issuer, each Lender shall be unconditionally and
irrevocably liable without regard to the occurrence of any Default or any
condition precedent whatsoever, to reimburse the LC Issuer on demand for (i)
such Lender's Pro Rata Share of the amount of each payment made by the LC Issuer
under each Facility LC to the extent such amount is not reimbursed by the
Borrower pursuant to Section 2.16 (e) below, plus (ii) interest on the foregoing
amount to be reimbursed by such Lender, for each day from the date of the LC
Issuer's demand for such reimbursement (or, if such demand is made after 11:00
a.m. (New York City time) on such date, from the next succeeding Business Day)
to the date on which such Lender pays the amount to be reimbursed by it, at a
rate of interest per annum equal to the Federal Funds Rate for the first three
days and, thereafter, at a rate of interest equal to the rate applicable to
Eurodollar Rate Advances.

            (e) Reimbursement by Borrower. The Borrower shall be irrevocably and
unconditionally obligated to reimburse the LC Issuer on or before the applicable
LC Payment Date for any amounts to be paid by the LC Issuer upon any drawing
under any Facility LC, without presentment, demand, protest or other formalities
of any kind; provided that neither the Borrower nor any Lender shall hereby be
precluded from asserting any claim for direct (but not consequential) damages
suffered by the Borrower or such Lender to the extent, but only to the extent,
caused by (i) the willful misconduct or gross negligence of the LC Issuer in
determining whether a request presented under any Facility LC issued by it
complied with the terms of such Facility LC or (ii) the LC Issuer's failure to
pay under any Facility LC issued by it after the presentation to it of a request
strictly complying with the terms and conditions of such Facility LC. All such
amounts paid by the LC Issuer and remaining unpaid by the Borrower shall bear
interest, payable on demand, for each day until paid at a rate per annum equal
to (x) the rate applicable to Base Rate Advances for such day if such day falls
on or before the applicable LC Payment Date and (y) the sum of 2% plus the rate
applicable to Base Rate Advances for such day if such day falls after such LC
Payment Date. The LC Issuer will pay to each Lender ratably in accordance with
its Pro Rata Share all amounts received by it from the Borrower for application
in payment, in whole or in part, of the Reimbursement Obligation in respect of
any Facility LC issued by the LC Issuer, but only to the extent such Lender has
made payment to the LC Issuer in respect of such Facility LC pursuant to Section
2.16(d). Subject to the terms and conditions of this Agreement (including
without limitation the submission of a Notice of Borrowing in

                                       25
<PAGE>

compliance with Section 2.02(a) and the satisfaction of the applicable
conditions precedent set forth in Section 3.02), the Borrower may request a
Revolving Credit Advance hereunder for the purpose of satisfying any
Reimbursement Obligation.

            (f) Obligations Absolute. The Borrower's obligations under this
Section 2.16 shall be absolute and unconditional under any and all circumstances
and irrespective of any setoff, counterclaim or defense to payment which the
Borrower may have or have had against the LC Issuer, any Lender or any
beneficiary of a Facility LC. The Borrower further agrees with the LC Issuer and
the Lenders that the LC Issuer and the Lenders shall not be responsible for, and
the Borrower's Reimbursement Obligation in respect of any Facility LC shall not
be affected by, among other things, the validity or genuineness of documents or
of any endorsements thereon, even if such documents should in fact prove to be
in any or all respects invalid, fraudulent or forged, or any dispute between or
among the Borrower, any of its Affiliates, the beneficiary of any Facility LC or
any financing institution or other party to whom any Facility LC may be
transferred or any claims or defenses whatsoever of the Borrower or of any of
its Affiliates against the beneficiary of any Facility LC or any such
transferee. The LC Issuer shall not be liable for any error, omission,
interruption or delay in transmission, dispatch or delivery of any message or
advice, however transmitted, in connection with any Facility LC. The Borrower
agrees that any action taken or omitted by the LC Issuer or any Lender under or
in connection with each Facility LC and the related drafts and documents, if
done without gross negligence or willful misconduct, shall be binding upon the
Borrower and shall not put the LC Issuer or any Lender under any liability to
the Borrower. Nothing in this Section 2.16(f) is intended to limit the right of
the Borrower to make a claim against any LC Issuer for damages as contemplated
by the proviso to the first sentence of Section 2.16(e).

            (g) Actions of LC Issuer. The LC Issuer shall be entitled to rely,
and shall be fully protected in relying, upon any Facility LC, draft, writing,
resolution, notice, consent, certificate, affidavit, letter, cablegram,
telegram, telecopy, telex or teletype message, statement, order or other
document believed by it to be genuine and correct and to have been signed, sent
or made by the proper Person or Persons, and upon advice and statements of legal
counsel, independent accountants and other experts selected by the LC Issuer.
The LC Issuer shall be fully justified in failing or refusing to take any action
under this Agreement unless it shall first have received such advice or
concurrence of the Required Lenders as it reasonably deems appropriate or it
shall first be indemnified to its reasonable satisfaction by the Lenders against
any and all liability and expense which may be incurred by it by reason of
taking or continuing to take any such action. Notwithstanding any other
provision of this Section 2.16, the LC Issuer shall in all cases be fully
protected in acting, or in refraining from acting, under this Agreement in
accordance with a request of the Required Lenders, and such request and any
action taken or failure to act pursuant thereto shall be binding upon the
Lenders and any future holders of a participation in any Facility LC.

            (h) Lenders' Indemnification. Each Lender shall, ratably in
accordance with its Pro Rata Share, indemnify the LC Issuer, its affiliates and
their respective directors, officers, agents and employees (to the extent not
reimbursed by the Borrower) against any cost, expense (including reasonable
counsel fees and disbursements), claim, demand, action, loss or liability
(except such as result from such indemnitees' gross negligence or willful
misconduct or the LC

                                       26
<PAGE>

Issuer's failure to pay under any Facility LC after the presentation to it of a
request strictly complying with the terms and conditions of the Facility LC)
that such indemnitees may suffer or incur in connection with this Section 2.16
or any action taken or omitted by such indemnitees hereunder.

            (i) Facility LC Collateral Account. The Borrower agrees that it
will, upon the request of the Agent or the Required Lenders and until the final
expiration date of any Facility LC and thereafter as long as any amount is
payable to any LC Issuer or the Lenders in respect of any Facility LC, maintain
a special collateral account pursuant to arrangements satisfactory to the Agent
(the "Facility LC Collateral Account") at the Agent's office at the address
specified pursuant to Section 8.02, in the name of the Borrower but under the
sole dominion and control of the Agent, for the benefit of the Lenders and in
which the Borrower shall have no interest other than as set forth in Section
6.01. The Borrower hereby pledges, assigns and grants to the Agent, on behalf of
and for the ratable benefit of the Lenders and any LC Issuer, a security
interest in all of the Borrower's right, title and interest in and to all funds
which may from time to time be on deposit in the Facility LC Collateral Account
to secure the prompt and complete payment and performance of the Obligations.
The Agent will invest any funds on deposit from time to time in the Facility LC
Collateral Account in certificates of deposit of the Agent having a maturity not
exceeding 30 days. Nothing in this Section 2.16(i) shall either obligate the
Agent to require the Borrower to deposit any funds in the Facility LC Collateral
Account or limit the right of the Agent to release any funds held in the
Facility LC Collateral Account in each case other than as required by Section
6.01.

            (j) Rights as a Lender. In its capacity as a Lender, each LC Issuer
shall have the same rights and obligations as any other Lender.

            SECTION 2.17. Noteless Agreement; Evidence of Indebtedness.

            (a) Each Lender shall maintain in accordance with its usual practice
an account or accounts evidencing the indebtedness of the Borrower to such
Lender resulting from each Credit Extension made by such Lender from time to
time, including the amounts of principal and interest payable and paid to such
Lender from time to time hereunder.

            (b) The Agent shall also maintain accounts in which it will record
(i) the date and the amount of each Credit Extension made hereunder and the
Interest Period, if any, applicable thereto, (ii) the amount of any principal or
interest due and payable or to become due and payable from the Borrower to each
Lender hereunder, (iii) the effective date and amount of each Assignment and
Acceptance delivered to and accepted by it and the parties thereto pursuant to
Section 8.07, (iv) the amount of any sum received by the Agent hereunder from
the Borrower and each Lender's share thereof, (v) the original stated amount of
each Facility LC and the amount of LC Obligations outstanding at any time, and
(vi) all other appropriate debits and credits as provided in this Agreement,
including, without limitation, all fees, charges, expenses and interest.

            (c) The entries maintained in the accounts maintained pursuant to
clauses (a) and (b) above shall be prima facie evidence of the existence and
amounts of the Obligations

                                       27
<PAGE>

hereunder and under the Notes therein recorded; provided, however, that the
failure of the Agent or any Lender to maintain such accounts or any error
therein shall not in any manner affect the obligation of the Borrower to repay
such Obligations in accordance with their terms.

            (d) Any Lender may request that its Revolving Credit Advances be
evidenced by a promissory note representing its Revolving Credit Advances
substantially in the form of Exhibit A (each, a "Note"). In such event, the
Borrower shall prepare, execute and deliver to such Lender such Note payable to
the order of such Lender. Thereafter, the Revolving Credit Advances evidenced by
each such Note and interest thereon shall at all times (including after any
assignment pursuant to Section 8.07) be represented by one or more Notes payable
to the order of the payee named therein or any assignee pursuant to Section
8.07, except to the extent that any such Lender or assignee subsequently returns
any such Note for cancellation and requests that such Revolving Credit Advances
once again be evidenced as described in clauses (a) and (b) above.

            (d) This Agreement has been, and each of the Notes and each of the
other Loan Documents to which it is a party when delivered hereunder will have

of an Environmental Action against the Borrower or any of the Significant
Subsidiaries or any of their properties that could have a Material Adverse
Effect or (ii) cause any such property to be subject to any restrictions on
ownership, occupancy, use or transferability under any Environmental Law that

for the purpose of purchasing or carrying margin stock (within the meaning of
Regulation U issued by the Board of Governors of the Federal Reserve System),
and no proceeds of any Credit Extension will be used to purchase or carry any
margin stock or to extend credit to others for the purpose of purchasing or
carrying any margin stock; and after applying the proceeds of each Credit
Extension hereunder, margin stock (within the meaning of Regulation U issued by
the Board of Governors of the Federal Reserve System) constitutes less than
twenty-five percent (25%) of the value of those assets of the Borrower and its

            SECTION 5.01. Affirmative Covenants. So long as any Outstanding
Credit Exposure shall remain unpaid or any Lender shall have any Commitment
hereunder, the Borrower will:

            (a) Compliance with Laws, Etc. Comply, and cause each of its
Subsidiaries to comply, in all material respects, with all applicable laws,

                                       32
<PAGE>

lawful claims that, if unpaid, might by law become a Lien upon its property;
provided, however, that neither the Borrower nor any of its Subsidiaries shall
be required to pay or discharge any such tax, assessment, charge or claim that
is being contested in good faith and by proper proceedings and as to which
appropriate reserves are being maintained, unless and until any Lien resulting
therefrom attaches to its property and becomes enforceable against its other
creditors.

Subsidiaries to maintain, insurance with responsible and reputable insurance
companies or associations in such amounts and covering such risks as is usually

            (d) Preservation of Corporate Existence, Etc. Preserve and maintain
its corporate existence, rights (charter and statutory) and franchises;
provided, however, that the Borrower shall not be required to preserve any right
or franchise if the Board of Directors of the Borrower or such Subsidiary shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Borrower and that the loss thereof is not disadvantageous in
any material respect to the Borrower or the Lenders.

            (e) Visitation Rights. At any reasonable time and from time to time,
permit the Agent or any of the Lenders or any agents or representatives thereof,
to examine and make copies of and abstracts from the records and books of
account of, and visit the properties of, the Borrower and any of the Significant
Subsidiaries, and to discuss the affairs, finances and accounts of the Borrower
and any of the Significant Subsidiaries with any of their officers or directors

            (i) The Borrower or any of its ERISA Affiliates shall incur, or, in

            Borrower and its Subsidiaries, (B) Excluded Hedging Debt and (C) the
            Junior Subordinated Debt) of not less than 2:1 for each twelve-month
            period ending on the last day of September, December, March and June
            of each year, or

            Hedging Debt and (C) the Junior Subordinated Debt) to Capitalization

            (k) any provision of any of the Loan Documents after delivery
thereof pursuant to Section 3.01 shall for any reason cease to be valid and
binding on or enforceable against the Borrower, or the Borrower shall so state
in writing;

then, and in any such event, the Agent (i) shall at the request, or may with the
consent, of the Required Lenders, by notice to the Borrower, declare the
obligation of each Lender and each LC Issuer to make Credit Extensions to be
terminated, whereupon the same shall forthwith terminate, (ii) shall at the
request, or may with the consent, of the Required Lenders, by notice to the
Borrower, declare the Aggregate Outstanding Credit Exposures, all interest
thereon and all other amounts payable under this Agreement to be forthwith due
and payable, whereupon the Aggregate Outstanding Credit Exposures, all such
interest and all such amounts shall become and be forthwith due and payable,
without presentment, demand, protest or further notice of any kind, all of which
are hereby expressly waived by the Borrower and (iii) shall at the request, or
may with the consent, of the Required Lenders upon notice to the Borrower and in
addition to the continuing right to demand payment of all amounts payable under
this Agreement, make demand on the Borrower to pay, and the Borrower will,
forthwith upon such demand and without any further notice or act, pay to the
Agent the Collateral Shortfall Amount (as defined below), which funds shall be
deposited in the Facility LC Collateral Account; provided, however, that in the
event of an actual or deemed entry of an order for relief with respect to the
Borrower under the Federal Bankruptcy Code, (A) the obligation of each Lender
and each LC Issuer to make Credit Extensions shall automatically be terminated,
(B) the Aggregate Outstanding Credit Exposures, all such interest and all such
amounts shall automatically become and be due and payable, without presentment,
demand, protest or any notice of any kind, all of which are hereby expressly
waived by the Borrower, and (C) the Borrower shall pay to the Agent an amount in
immediately available funds, which funds shall be held in the Facility LC
Collateral Account,

                                       37
<PAGE>

equal to the difference of (x) the amount of LC Obligations at such time, less
(y) the amount on deposit in the Facility LC Collateral Account at such time
which is free and clear of all rights and claims of third parties and has not
been applied against the Obligations (such difference, the "Collateral Shortfall
Amount"). If at any time while any Default is continuing, the Agent determines
that the Collateral Shortfall Amount at such time is greater than zero, the
Agent may make demand on the Borrower to pay, and the Borrower will, forthwith
upon such demand and without any further notice or act, pay to the Agent the
Collateral Shortfall Amount, which funds shall be deposited in the Facility LC
Collateral Account. The Agent may at any time or from time to time after funds
are deposited in the Facility LC Collateral Account, apply such funds to the
payment of the Obligations and any other amounts as shall from time to time have
become due and payable by the Borrower to the Lenders or the LC Issuer under the
Loan Documents. At any time while any Default is continuing, neither the
Borrower nor any Person claiming on behalf of or through the Borrower shall have
any right to withdraw any of the funds held in the Facility LC Collateral
Account. After all of the Obligations have been indefeasibly paid in full and
the aggregate Commitments have been terminated, any funds remaining in the
Facility LC Collateral Account shall be returned by the Agent to the Borrower or
paid to whomever may be legally entitled thereto at such time.

                             ARTICLE VII: THE AGENT

            SECTION 7.01. Authorization and Action. Each Lender hereby appoints
and authorizes the Agent to take such action as agent on its behalf and to
exercise such powers and discretion under this Agreement as are delegated to the
Agent by the terms hereof, together with such powers and discretion as are
reasonably incidental thereto. As to any matters not expressly provided for by
this Agreement (including, without limitation, enforcement or collection of the
Outstanding Credit Exposures), the Agent shall not be required to exercise any
discretion or take any action, but shall be required to act or to refrain from
acting (and shall be fully protected in so acting or refraining from acting)
upon the instructions of the Required Lenders (or all of the Lenders to the
extent required by the terms of this Agreement), and such instructions shall be
binding upon all Lenders and all holders of Outstanding Credit Exposures;
provided, however, that the Agent shall not be required to take any action that
exposes the Agent to personal liability or that is contrary to this Agreement or
applicable law. The Agent agrees to give to each Lender prompt notice of each
notice given to it by the Borrower pursuant to the terms of this Agreement.

            SECTION 7.02. Agent's Reliance, Etc. Neither the Agent nor any of
its directors, officers, agents or employees shall be liable for any action
taken or omitted to be taken by it or them under or in connection with this
Agreement, except for its or their own gross negligence or willful misconduct.
Without limitation of the generality of the foregoing, the Agent: (i) may treat
the payee in respect of any Outstanding Credit Exposure as the owner thereof
until the Agent receives and accepts an Assignment and Acceptance entered into
by the Lender that is the payee in respect of such Outstanding Credit Exposure,
as assignor, and an Eligible Assignee, as assignee, as provided in Section 8.07;
(ii) may consult with legal counsel (including counsel for the Borrower),
independent public accountants and other experts selected

                                       38
<PAGE>

by it and shall not be liable for any action taken or omitted to be taken in
good faith by it in accordance with the advice of such counsel, accountants or
experts; (iii) makes no warranty or representation to any Lender and shall not
be responsible to any Lender for any statements, warranties or representations
(whether written or oral) made in or in connection with this Agreement; (iv)
shall not have any duty to ascertain or to inquire as to the performance or
observance of any of the terms, covenants or conditions of this Agreement on the
part of the Borrower or to inspect the property (including the books and
records) of the Borrower; (v) shall not be responsible to any Lender for the due
execution, legality, validity, enforceability, genuineness, sufficiency or value
of, or the perfection or priority of any lien or security interest created or
purported to be created under or in connection with, any Loan Document or any
other instrument or document furnished pursuant hereto; and (vi) shall incur no
liability under or in respect of this Agreement by acting upon any notice,
consent, certificate or other instrument or writing (which may be by telecopier,
telegram or telex) believed by it to be genuine and signed or sent by the proper
party or parties.

            SECTION 7.03. Barclays and Affiliates. With respect to its
Commitment, the Credit Extensions made by it and any Note issued to it, Barclays
shall have the same rights and powers under this Agreement as any other Lender
and may exercise the same as though it were not the Agent; and the term "Lender"
or "Lenders" shall, unless otherwise expressly indicated, include Barclays in
its individual capacity. Barclays and its Affiliates may accept deposits from,
lend money to, act as trustee under indentures of, accept investment banking
engagements from and generally engage in any kind of business with, the
Borrower, any of its Subsidiaries and any Person who may do business with or own
securities of the Borrower or any such Subsidiary, all as if Barclays were not
the Agent and without any duty to account therefor to the Lenders.

            SECTION 7.04. Lender Credit Decision. Each Lender acknowledges that
it has, independently and without reliance upon the Agent or any other Lender
and based on the financial statements referred to in Section 4.01 and such other
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the Agent or
any other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement.

            SECTION 7.05. Indemnification. The Lenders agree to indemnify the
Agent (to the extent not reimbursed by the Borrower), ratably according to the
respective principal amounts of their respective Outstanding Credit Exposures
(or if the Aggregate Outstanding Credit Exposures are zero or if any Credit
Extensions are owing to Persons that are not Lenders, ratably according to the
respective amounts of their Commitments), from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever that may be
imposed on, incurred by, or asserted against the Agent in any way relating to or
arising out of any Loan Document or any action taken or omitted by the Agent
under any Loan Document, provided that no Lender shall be liable for any portion
of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from the Agent's

                                       39
<PAGE>

gross negligence or willful misconduct. Without limitation of the foregoing,
each Lender agrees to reimburse the Agent promptly upon demand for its ratable
share of any out-of-pocket expenses (including counsel fees) incurred by the
Agent in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, any Loan Document, to the extent that the Agent is not
reimbursed for such expenses by the Borrower.

            SECTION 7.06. Successor Agent. The Agent may resign at any time by
giving written notice thereof to the Lenders and the Borrower and may be removed
at any time with or without cause by the Required Lenders. Upon any such
resignation or removal, the Required Lenders shall have the right to appoint a
successor Agent. If no successor Agent shall have been so appointed by the
Required Lenders, and shall have accepted such appointment, within 30 days after
the retiring Agent's giving of notice of resignation or the Required Lenders'
removal of the retiring Agent, then the retiring Agent may, on behalf of the
Lenders, appoint a successor Agent, which shall be a commercial bank organized
under the laws of the United States of America or of any State thereof and
having a combined capital and surplus of at least $50,000,000. Upon the
acceptance of any appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the
rights, powers, discretion, privileges and duties of the retiring Agent, and the
retiring Agent shall be discharged from its duties and obligations under this
Agreement. After any retiring Agent's resignation or removal hereunder as Agent,
the provisions of this Article VII shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Agent under this Agreement.

                          ARTICLE VIII: MISCELLANEOUS

            SECTION 8.01. Amendments, Etc. No amendment or waiver of any
provision of this Agreement or the Notes, nor consent to any departure by the
Borrower therefrom, shall in any event be effective unless the same shall be in

            SECTION 8.03. No Waiver; Remedies. No failure on the part of any
Lender or the Agent to exercise, and no delay in exercising, any right hereunder

Agent, each LC Issuer and each Lender in connection with the enforcement of
rights under this Section 8.04(a).

                                       41

            (b) The Borrower agrees to indemnify, to the extent legally
permissible, and hold harmless the Agent, each LC Issuer and each Lender and
each of their Affiliates and their officers, directors, employees, agents and
advisors (each, an "Indemnified Party") from and against any and all claims,
damages, losses, liabilities and expenses (including, without limitation,
reasonable fees and expenses of counsel) that may be incurred by or asserted or
awarded against any Indemnified Party, in each case arising out of or in
connection with or by reason of, or in connection with the preparation for a
defense of, any investigation, litigation or proceeding arising out of, related
to or in connection with (i) the Notes, this Agreement, the other Loan
Documents, any Facility LC, any of the transactions contemplated herein or
therein or the actual or proposed use of the proceeds of the Credit Extensions
or (ii) the actual or alleged presence of Hazardous Materials on any property of
the Borrower or any of its Subsidiaries or any Environmental Action relating in
any way to the Borrower or any of its Subsidiaries, in each case whether or not
such investigation, litigation or proceeding is brought by the Borrower, its
directors, shareholders or creditors or an Indemnified Party or any other Person
or any Indemnified Party is otherwise a party thereto and whether or not the
transactions contemplated hereby are consummated, except to the extent such
claim, damage, loss, liability or expense is found in a final, non-appealable
judgment by a court of competent jurisdiction to have resulted from such
Indemnified Party's gross negligence or willful misconduct; provided that the
Borrower shall not be required to indemnify the LC Issuer or the Agent for any
claims, damages, losses, liabilities or expenses to the extent, but only to the
extent, caused by (x) the willful misconduct or gross negligence of the LC
Issuer in determining whether a request presented under any Facility LC complied
with the terms of such Facility LC or (y) the LC Issuer's failure to pay under
any Facility LC after the presentation to it of a request strictly complying
with the terms and conditions of such Facility LC. The Borrower also agrees not
to assert any claim against the Agent, any LC Issuer, any Lender, any of their
Affiliates, or any of their respective directors, officers, employees, attorneys
and agents, on any theory of liability, for special, indirect, consequential or
punitive damages arising out of or otherwise relating to the Notes, this
Agreement, the other Loan Documents, any Facility LC, any of the transactions
contemplated herein or therein or the actual or proposed use of the proceeds of
the Credit Extensions.

            (c) If any payment of principal of, or Conversion of, any Eurodollar
Rate Advance is made by the Borrower to or for the account of a Lender other
than on the last day of the Interest Period for such Revolving Credit Advance,
as a result of a payment or Conversion pursuant to Section 2.07(d) or (e), 2.09
or 2.11, acceleration of the maturity of the Revolving Credit Advances pursuant
to Section 6.01, or for any other reason, the Borrower shall, upon demand by
such Lender (with a copy of such demand to the Agent), pay to the Agent for the
account of such Lender any amounts required to compensate such Lender for any
additional losses, costs or expenses that it may reasonably incur as a result of
such payment or Conversion, including, without limitation, any loss (including
loss of anticipated profits), cost or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by any Lender to
fund or maintain such Credit Extension.

            (d) Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of the Borrower contained in
Sections 2.10, 2.13 and

                                       42
<PAGE>

8.04 shall survive the payment in full of principal, interest and all other
amounts payable hereunder and under the Notes.

            SECTION 8.05. Right of Set-off. Upon (i) the occurrence and during
the continuance of any Event of Default and (ii) the making of the request or
the granting of the consent specified by Section 6.01 to authorize the Agent to
declare the Aggregate Outstanding Credit Exposures due and payable pursuant to
the provisions of Section 6.01, each Lender, each LC Issuer and each of its
Affiliates is hereby authorized at any time and from time to time, to the
fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by such Lender, such LC Issuer or such
Affiliate to or for the credit or the account of the Borrower against any and
all of the obligations of the Borrower now or hereafter existing under the Loan
Documents and any Note held by such Lender or such LC Issuer, whether or not
such Lender or such LC Issuer shall have made any demand under this Agreement or
such Note and although such obligations may be unmatured. Each Lender and each
LC Issuer agrees promptly to notify the Borrower after any such set-off and
application, provided that the failure to give such notice shall not affect the
validity of such set-off and application. The rights of each Lender, each LC
Issuer and their respective Affiliates under this Section are in addition to
other rights and remedies (including, without limitation, other rights of
set-off) that such Lender, such LC Issuer and their respective Affiliates may
have.

            SECTION 8.06. Binding Effect. This Agreement shall become effective
(other than Section 2.01, which shall only become effective upon satisfaction of
the conditions precedent set forth in Section 3.01) when it shall have been
executed by the Borrower and the Agent and when the Agent shall have been
notified by each Initial Lender that such Initial Lender has executed it and
thereafter shall be binding upon and inure to the benefit of the Borrower, the
Agent, each LC Issuer and each Lender and their respective successors and
assigns, except that the Borrower shall not have the right to assign its rights
hereunder or any interest herein without the prior written consent of the
Lenders to any Person.

            SECTION 8.06. Assignments, Designations and Participations. (a) Each
Lender may (i) with the prior consent of the Agent (which consent shall not be
unreasonably withheld), (ii) for so long as no Default has occurred and is
continuing, with the consent of the Borrower (which consent shall not be
unreasonably withheld), and (iii) with the prior consent of the LC Issuer (which
consent may be given or withheld in the sole discretion of the LC Issuer),
assign to one or more Persons all or a portion of its rights and obligations
under this Agreement (including, without limitation, all or a portion of its
Commitment, the Outstanding Credit Exposures owed to it and any Note or Notes
held by it); provided, however, that (A) no consent of the LC Issuer shall be
required if no amounts remain available to be drawn under any Facility LC and
the assigning Lender has made all payments required to be made by it to the LC
Issuer pursuant to Section 2.16 hereof, and that the LC Issuer may not assign
its direct obligations under the Facility LC, (B) each such assignment shall be
of a constant, and not a varying, percentage of all rights and obligations under
this Agreement, (C) except in the case of an assignment to a Person that,
immediately prior to such assignment, was a Lender or an assignment of all of a
Lender's rights and obligations under this Agreement, the amount of the
Commitment of the assigning Lender being assigned pursuant to each such
assignment

                                       43
<PAGE>

(determined as of the date of the Assignment and Acceptance with respect to such
assignment) shall in no event be less than $10,000,000 or an integral multiple
of $1,000,000 in excess thereof, (D) each such assignment shall be to an
Eligible Assignee, and (E) the parties to each such assignment shall execute and
deliver to the Agent, for its acceptance and recording in the Register, an
Assignment and Acceptance, together with any Note subject to such assignment and
a processing and recordation fee of $3,000. Upon such execution, delivery,
acceptance and recording, from and after the effective date specified in each
Assignment and Acceptance, (1) the assignee thereunder shall be a party hereto
and, to the extent that rights and obligations hereunder have been assigned to
it pursuant to such Assignment and Acceptance, have the rights and obligations
of a Lender hereunder and (2) the Lender assignor thereunder shall, to the
extent that rights and obligations hereunder have been assigned by it pursuant
to such Assignment and Acceptance, relinquish its rights and be released from
its obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all or the remaining portion of an assigning Lender's rights
and obligations under this Agreement, such Lender shall cease to be a party
hereto).

            (b) By executing and delivering an Assignment and Acceptance, the
Lender assignor thereunder and the assignee thereunder confirm to and agree with
each other and the other parties hereto as follows: (i) other than as provided
in such Assignment and Acceptance, such assigning Lender makes no representation
or warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of, or the perfection or priority of any lien or security interest created
or purported to be created under or in connection with, this Agreement or any
other instrument or document furnished pursuant hereto; (ii) such assigning
Lender makes no representation or warranty and assumes no responsibility with
respect to the financial condition of the Borrower or the performance or
observance by the Borrower of any of its obligations under this Agreement or any
other instrument or document furnished pursuant hereto; (iii) such assignee
confirms that it has received a copy of this Agreement, together with copies of
the financial statements referred to in Section 4.01 and such other documents
and information as it has deemed appropriate to make its own credit analysis and
decision to enter into such Assignment and Acceptance; (iv) such assignee will,
independently and without reliance upon the Agent, such assigning Lender or any
other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement; (v) such assignee confirms that it is an
Eligible Assignee; (vi) such assignee appoints and authorizes the Agent to take
such action as agent on its behalf and to exercise such powers and discretion
under this Agreement as are delegated to the Agent by the terms hereof, together
with such powers and discretion as are reasonably incidental thereto; and (vii)
such assignee agrees that it will perform in accordance with their terms all of
the obligations that by the terms of this Agreement are required to be performed
by it as a Lender.

            (c) Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender and an assignee representing that it is an Eligible Assignee,
together with any Note or Notes subject to such assignment, the Agent shall, if
such Assignment and Acceptance has been completed and is in substantially the
form of Exhibit C hereto, (i) accept such

                                       44
<PAGE>

Assignment and Acceptance, (ii) record the information contained therein in the
Register and (iii) give prompt notice thereof to the Borrower. Within five
Business Days after the Borrower's receipt of such notice, if requested by the
applicable Lender, the Borrower, at its own expense, shall execute and deliver
to the Agent in exchange for the surrendered Note a new Note to the order of
such Eligible Assignee in an amount equal to the Commitment assumed by it
pursuant to such Assignment and Acceptance and, if the assigning Lender has
retained a Commitment hereunder, if requested by such assigning Lender, a new
Note to the order of the assigning Lender in an amount equal to the Commitment
retained by it hereunder. Such new Note or Notes shall be in an aggregate
principal amount equal to the aggregate principal amount of such surrendered
Note or Notes, shall be dated the effective date of such Assignment and
Acceptance and shall otherwise be in substantially the form of Exhibit A hereto.

            (d) The Agent shall maintain at its address referred to in Section
8.02 a copy of each Assignment and Acceptance delivered to and accepted by it
and a register for the recordation of the names and addresses and Commitment of,
and principal amount of Outstanding Credit Exposure owing to, each Lender from
time to time (the "Register"). The entries in the Register shall be conclusive
and binding for all purposes, absent manifest error, and the Borrower, the Agent
and the Lenders may treat each Person whose name is recorded in the Register as
a Lender hereunder for all purposes of this Agreement. The Register shall be
available for inspection by the Borrower or any Lender at any reasonable time
and from time to time upon reasonable prior notice.

            (e) Each Lender may sell participations to one or more banks or
other entities (other than the Borrower or any of its Affiliates) in or to all
or a portion of its rights and obligations under this Agreement (including,
without limitation, all or a portion of its Commitment, the Outstanding Credit
Exposure owing to it and any Note or Notes held by it); provided, however, that
(i) such Lender's obligations under this Agreement (including, without
limitation, its Commitment to the Borrower hereunder) shall remain unchanged,
(ii) such Lender shall remain solely responsible to the other parties hereto for
the performance of such obligations, (iii) such Lender shall remain the owner of
such Credit Extensions for all purposes of this Agreement, (iv) the Borrower,
the Agent and the other Lenders shall continue to deal solely and directly with
such Lender in connection with such Lender's rights and obligations under this
Agreement and (v) no participant under any such participation shall have any
right to approve any amendment or waiver of any provision of this Agreement or
any Note, or any consent to any departure by the Borrower therefrom, except to
the extent that such amendment, waiver or consent would (A) reduce the principal
of, or interest on, the Credit Extensions or any fees or other amounts payable
hereunder, or (B) increase the Commitments, in each case to the extent subject
to such participation, or postpone any date fixed for any payment of principal
of, or interest on, the Aggregate Outstanding Credit Exposures or any fees or
other amounts payable hereunder, in each case to the extent subject to such
participation. Each participant shall be entitled to the benefits of Sections
2.10, 2.11 and 2.13 to the same extent as if it were a Lender and had acquired
its interest under this Agreement by an assignment made pursuant to this Section
8.07, provided, however, that in no event shall the Borrower be obligated to
make any payment with respect to such Sections that is greater than the amount
that the Borrower would have otherwise made had no participations been sold
under this Section 8.07(e).

                                       45
<PAGE>

            (f) Any Lender may, in connection with any assignment, designation
or participation or proposed assignment, designation or participation pursuant
to this Section 8.07, disclose to the assignee, designee or participant or
proposed assignee, designee or participant, any information relating to the
Borrower furnished to such Lender by or on behalf of the Borrower; provided
that, prior to any such disclosure, the assignee, designee or participant or
proposed assignee, designee or participant shall agree to preserve the
confidentiality of any Confidential Information relating to the Borrower
received by it from such Lender.

            (g) Notwithstanding any other provision set forth in this Agreement,
any Lender may at any time (i) create a security interest in all or a portion of
its rights under this Agreement (including, without limitation, the Outstanding
Credit Exposure owing to it and the Note or Notes held by it) in favor of any
Federal Reserve Bank in accordance with Regulation A of the Board of Governors
of the Federal Reserve System or (ii) with notice to the Agent and the Borrower,
assign all or a portion of its rights and obligations under this Agreement
(including, without limitation, all or a portion of its Commitment, the
Outstanding Credit Exposure owed to it and the Note or Notes held by it) to any
of its Affiliates.

            (h) Notwithstanding anything to the contrary contained herein, any
Lender (a "Designating Lender") may grant to one or more special purpose funding
vehicles (each an "SPV"), identified as such in writing from time to time by the
Designating Lender to the Agent and the Borrower, the option to provide to the
Borrower all or any part of any Revolving Credit Advance that such Designating
Lender would otherwise be obligated to make to the Borrower or to participate in
any Facility LC pursuant to this Agreement; provided that (i) nothing herein
shall constitute a commitment by any SPV to make any Revolving Credit Advance or
to participate in any Facility LC issued hereunder , (ii) if an SPV elects not
to exercise such option or otherwise fails to provide all or any part of such
Revolving Credit Advance, the Designating Lender shall be obligated to make such
Revolving Credit Advance pursuant to the terms hereof, (iii) the Designating
Lender shall remain liable for any indemnity or other payment obligation with
respect to its Commitment hereunder and (iv) no SPV or Designating Lender shall
be entitled to receive any greater amount under this Agreement than the
Designating Lender would have been entitled to receive had the Designating
Lender not otherwise granted such SPV the option to provide any Revolving Credit
Advance to the Borrower. The making of a Revolving Credit Advance by an SPV
hereunder and the participation of an SPV in any Facility LC issued hereunder
shall utilize the Commitment of the Designating Lender to the same extent, and
as if, such Revolving Credit Advance or participation in such Facility LC were
made by such Designating Lender.

            (i) Each party hereto hereby acknowledges and agrees that no SPV
shall have the rights of a Lender hereunder, such rights being retained by the
applicable Designating Lender. Accordingly, and without limiting the foregoing,
each party hereby further acknowledges and agrees that no SPV shall have any
voting rights hereunder and that the voting rights attributable to any Credit
Extension made by an SPV shall be exercised only by the relevant Designating
Lender and that each Designating Lender shall serve as the administrative agent
and attorney-in-fact for its SPV and shall on behalf of its SPV receive any and
all payments made for the benefit of such SPV and take all actions hereunder to
the extent, if any, such SPV shall have any rights hereunder. No additional Note
shall be required to evidence the

                                       46
<PAGE>

Credit Extensions or portion thereof made by an SPV; and the related Designating
Lender shall be deemed to hold its Note or Notes, if any, as administrative
agent for such SPV to the extent of the Credit Extensions or portion thereof
funded by such SPV. In addition, any payments for the account of any SPV shall
be paid to its Designating Lender as administrative agent for such SPV.

            (j) Each party hereto hereby agrees that no SPV shall be liable for
any indemnity or payment under this Agreement for which a Lender would otherwise
be liable so long as, and to the extent that, the related Designating Lender
provides such indemnity or makes such payment; provided, with respect to such
agreement by the Borrower that the related Designating Lender shall not be in
breach of its obligation to make Credit Extensions to the Borrower hereunder. In
furtherance of the foregoing, each party hereto hereby agrees (which agreements
shall survive the termination of this Agreement) that prior to the date that is
one year and one day after the payment in full of all outstanding commercial
paper or other senior indebtedness of any SPV, it will not institute against, or
join any other person in instituting against, such SPV any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceedings under the
laws of the United States or any State thereof; provided, with respect to such
agreement by the Borrower that the related Designating Lender shall not be in
breach of its obligation to make Credit Extensions to the Borrower hereunder.
Notwithstanding the foregoing, the Designating Lender unconditionally agrees to
indemnify the Borrower, the Agent and each Lender against all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever which may be incurred
by or asserted against the Borrower, the Agent or such Lender, as the case may
be, in any way relating to or arising as a consequence of any such forbearance
or delay in the initiation of any such proceeding against its SPV.

            (k) In addition, notwithstanding anything to the contrary contained
in subsection 8.07(h), (i), (j) or (k) or otherwise in this Agreement, any SPV
may (i) at any time and without paying any processing fee therefor, assign or
participate all or a portion of its interest in any Outstanding Credit Exposure
to the Designating Lender or to any financial institutions providing liquidity
and/or credit support to or for the account of such SPV to support the funding
or maintenance of Outstanding Credit Exposure and (ii) disclose on a
confidential basis any non-public information relating to its Outstanding Credit
Exposure to any rating agency, commercial paper dealer or provider of any
surety, guarantee or credit or liquidity enhancements to such SPV. Subsection
8.07(h), (i), (j) or (k) may not be amended without the written consent of any
Designating Lender affected thereby.

            SECTION 8.08. Confidentiality. Neither the Agent nor any Lender
shall disclose any Confidential Information to any other Person without the
consent of the Borrower, other than (a) to the Agent's or such Lender's
Affiliates and their officers, directors, employees, agents and advisors and, as
contemplated by Section 8.07(f), to actual or prospective assignees and
participants, and then only on a confidential basis, (b) as required by any law,
rule or regulation or judicial process, (c) to any rating agency when required
by it, provided that, prior to any such disclosure, such rating agency shall
undertake to preserve the confidentiality of any Confidential Information
relating to the Borrower received by it from such Lender, (d) as requested or
required by any state, federal or foreign authority or examiner regulating banks
or banking and (e) on a confidential basis, to any Lender's direct or indirect
contractual

                                       47
<PAGE>

counterparties in swap agreements or to legal counsel, accountants and other
professional advisors to such counterparties. Notwithstanding anything herein to
the contrary, Confidential Information shall not include, and each party hereto
(and each employee, representative or other agent of any party hereto) may
disclose to any and all persons, without limitation of any kind, the U.S.
federal income tax treatment and U.S. federal income tax structure of the
transactions contemplated hereby and all materials of any kind (including
opinions or other tax analyses) that are or have been provided to such party
relating to such tax treatment or tax structure, and it is hereby confirmed that
each party hereto has been authorized to make such disclosures since the
commencement of discussions regarding the transactions contemplated hereby.

            SECTION 8.09. Governing Law. This Agreement and the Notes shall be
governed by, and construed in accordance with, the laws of the State of New
York.

            SECTION 8.10. Execution in Counterparts. This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement. Delivery of an executed counterpart of a signature page to this
Agreement by telecopier shall be effective as delivery of a manually executed
counterpart of this Agreement.

            SECTION 8.11. Jurisdiction, Etc. (a) Each of the parties hereto
hereby irrevocably and unconditionally submits, for itself and its property, to
the nonexclusive jurisdiction of any New York State court or federal court of
the United States of America sitting in New York, and any appellate court from
any thereof, in any action or proceeding arising out of or relating to this
Agreement or the Notes, or for recognition or enforcement of any judgment, and
each of the parties hereto hereby irrevocably and unconditionally agrees that
all claims in respect of any such action or proceeding may be heard and
determined in any such New York State court or, to the extent permitted by law,
in such federal court. Each of the parties hereto agrees that a final judgment
in any such action or proceeding shall be conclusive and may be enforced in
other jurisdictions by suit on the judgment or in any other manner provided by
law. Nothing in this Agreement shall affect any right that any party may
otherwise have to bring any action or proceeding relating to this Agreement or
the Notes in the courts of any jurisdiction.

            (b) Each of the parties hereto irrevocably and unconditionally
waives, to the fullest extent it may legally and effectively do so, any
objection that it may now or hereafter have to the laying of venue of any suit,
action or proceeding arising out of or relating to this Agreement or the Notes
in any New York State or federal court. Each of the parties hereto hereby
irrevocably waives, to the fullest extent permitted by law, the defense of an
inconvenient forum to the maintenance of such action or proceeding in any such
court.

            SECTION 8.12. Waiver of Jury Trial. Each of the Borrower, the Agent,
the LC Issuers and the Lenders hereby irrevocably waives all right to trial by
jury in any action, proceeding or counterclaim (whether based on contract, tort
or otherwise) arising out of or relating to this Agreement or the Notes or the
actions of the Agent, any LC Issuer or any Lender in the negotiation,
administration, performance or enforcement thereof.

      IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be

            In that connection, I, in conjunction with the members of my staff,
have examined:

            (i) Each Loan Document, executed by each of the parties thereto.

            (ii) The other documents furnished by the Borrower pursuant to
      Article III of the Credit Agreement.

            (iii) The Restated Articles of Incorporation of the Borrower and all
      amendments thereto (the "Charter").

            (iv) The By-Laws of the Borrower and all amendments thereto (the
      "By-Laws").

            (v) A certificate from the State of Michigan attesting to the
      continued corporate existence and good standing of the Borrower.

I have also examined the originals, or copies certified to my satisfaction, of
the documents listed in a certificate of a Financial Officer of the Borrower,
dated the date hereof (the "Certificate"), certifying that the documents listed
in such certificate are all of the indentures, loan or credit agreements,
leases, guarantees, mortgages, security agreements, bonds, notes and other
agreements or instruments, and all of the orders, writs, judgments, awards,
injunctions and decrees, that affect or purport to affect the Borrower's right
to borrow money or the Borrower's obligations under the Loan Documents to which
it is party. In addition, I have examined the

<PAGE>

originals, copies certified to my satisfaction, of such other corporate records
of the Borrower, certificates of public officials and of officers of the
Borrower, and agreements, instruments and other documents, as I have deemed
necessary as a basis for the opinions expressed below. As to questions of fact
material to such opinions, I have, when relevant facts were not independently
established by me, relied upon certificates of public officials. I have assumed
the due execution and delivery, pursuant to due authorization, of the Credit
Agreement by the Lenders and the Agent.

            My opinions expressed below are limited to the law of the State of
Michigan and the federal law of the United States.

            Based upon the foregoing and upon such investigation as I have
deemed necessary, I am of the following opinion:

            1. The Borrower is a corporation duly organized, validly existing
and in good standing under the laws of the State of Michigan.

            2. The execution, delivery and performance by the Borrower of the
Loan Documents to which it is party, and the consummation of the transactions
contemplated thereby, are within the Borrower's corporate powers, have been duly
authorized by all necessary corporate action, and do not contravene (i) the
Charters or the By-Laws of the Borrower or (ii) any law, rule or regulation
applicable to the Borrower (including, without limitation, Regulation X of the
Board of Governors of the Federal Reserve System) or (iii) any contractual or
legal restriction contained in any document listed in the Certificate or, to the
best of my knowledge (after due inquiry), contained in any other similar
document.

            3. No authorization, approval or other action by, and no notice to
or filing with, any governmental authority or regulatory body or any other third
party is required for the due execution, delivery, recordation, filing or
performance by the Borrower of the Loan Documents to which it is a party, except
such as have been obtained.

            4. Each Loan Document has been duly executed and delivered on behalf
of the Borrower.

            5. Except as may have been disclosed to you in the SEC Reports
designated in the Certificate, to the best of my knowledge (after due inquiry)
there are no pending or overtly threatened actions or proceedings affecting the
Borrower or any of its Subsidiaries before any court, governmental agency or
arbitrator that (i) could be reasonably likely to have a Material Adverse Effect
or (ii) purport to affect the legality, validity, binding effect or
enforceability of any Loan Documents or the consummation of the transactions
contemplated thereby.

            6. In a properly presented case, a Michigan court or a federal court
sitting in the State of Michigan applying Michigan choice of law rules should
give effect to the choice of law provisions of the Loan Documents and should
hold that such Loan Documents are to be governed by the laws of the State of New
York rather than the laws of the State of Michigan. In rendering the foregoing
opinion, I note that by their terms the Loan Documents expressly select New York
law as the laws governing their interpretation and that the Loan Documents
governed

<PAGE>

by New York law were delivered by the parties thereto to the Agent in New York.
The choice of law provisions of the Loan Documents are not voidable under the
laws of the State of Michigan.

            7. If, despite the provisions of Section 8.09 of the Credit
Agreement wherein the parties thereto agree that the Loan Documents shall be
governed by, and construed in accordance with, the laws of the State of New
York, a court of the State of Michigan or a federal court sitting in the State
of Michigan were to hold that the Loan Documents are governed by, and to be
construed in accordance with the laws of the State of Michigan, the respective
Loan Documents would be, under the laws of the State of Michigan, legal, valid
and binding obligations of the Borrower, enforceable against the Borrower in
accordance with their respective terms.

            8. Neither the Borrower nor any of its Subsidiaries is an
"investment company," or an "affiliated person" of, or "promoter" or "principal
underwriter" for, an "investment company," as such terms are defined in the
Investment Company Act of 1940, as amended; DECO is a "public utility company"
and a "subsidiary company" of the Borrower, which is a "holding company" as such
terms are defined in the Public Utility Holding Company Act of 1935, as amended
(the "1935 Act"), and such "holding company" and The Detroit Edison Company are
currently exempt from the provisions of the 1935 Act (except Section 9 thereof);
and Michigan Consolidated Gas Company is a "public utility company" and a
"subsidiary company" of MichCon Holdings, Inc., which is a "holding company" and
a "subsidiary company" of DTE Enterprises, Inc., which is a "holding company"
and a "subsidiary company" of the Borrower, as such terms are defined in the
1935 Act, and such "holding companies" and Michigan Consolidated Gas Company are
currently exempt from the provisions of the 1935 Act (except Section 9 thereof);

            The opinions set forth above are subject to the following
qualifications:

                  (a) My opinion in paragraph 7 above as to enforceability is
            subject to the effect of any applicable bankruptcy, insolvency
            (including, without limitation, all laws relating to fraudulent
            transfers), reorganization, moratorium or similar law affecting
            creditors' rights generally.

                  (b) My opinion in paragraph 7 above as to enforceability is
            subject to the effect of general principles of equity, including,
            without limitation, concepts of materiality, reasonableness, good
            faith and fair dealing (regardless of whether considered in a
            proceeding in equity or at law).

                  (c) I express no opinion as to participation and the effect of
            the law of any jurisdiction other than the State of Michigan wherein
            any Lender may be located or wherein enforcement of the Loan
            Documents may be sought that limits the rates of interest legally
            chargeable or collectible.

                                           Very truly yours,
