the Agent's Account, in same day funds, such Lender's ratable portion of such
Revolving Credit Borrowing. After the Agent's receipt of such funds and upon
fulfillment of the applicable conditions set forth in Article III, the Agent
will make such funds available to the Borrower 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 Revolving
Credit Borrowing if the aggregate amount of such Revolving Credit 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 2.08 or 2.12 and (ii) the
Eurodollar Rate Advances may not be outstanding as part of more than ten
separate Revolving Credit Borrowings.

         (c) Each Notice of Revolving Credit Borrowing shall be irrevocable and
binding on the Borrower. In the case of any Revolving Credit Borrowing that the
related Notice of Revolving Credit Borrowing specifies is to be comprised of
Eurodollar Rate Advances, the Borrower shall 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 Revolving Credit
Borrowing for such Revolving Credit Borrowing the applicable conditions set
forth in Article III, 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 such Lender to fund the
Revolving Credit Advance to be made by such Lender as part of such Revolving
Credit 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 Revolving Credit Borrowing that such Lender will not make
available to the Agent such Lender's ratable portion of such Revolving Credit
Borrowing, the Agent may assume that such Lender has made such portion available
to the Agent on the date of such Revolving Credit 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 ratable
portion available to the Agent, such Lender and the Borrower severally agree to
repay to the Agent forthwith on demand such corresponding amount together with
interest thereon, for each day from the date such amount is made available to
the Borrower until the date such amount is repaid to the Agent, at (i) in the
case of the Borrower, the interest rate applicable at the time to Revolving
Credit Advances comprising such Revolving Credit 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 Revolving Credit Borrowing for purposes
of this Agreement.
<PAGE>   20

         (e) The failure of any Lender to make the Revolving Credit Advance to
be made by it as part of any Revolving Credit Borrowing shall not relieve any
other Lender of its obligation, if any, hereunder to make its Revolving Credit
Advance on the date of such Revolving Credit 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 Revolving Credit
Borrowing.

              SECTION 2.03. The Competitive Bid Advances. (a) Each Lender
severally agrees that the Borrower may make Competitive Bid Borrowings under
this Section 2.03 from time to time on any Business Day during the period from
the date hereof until the date occurring 30 days prior to the earlier of the
Revolver Termination Date and the Term Loan Conversion Date in the manner set
forth below; provided that, following the making of each Competitive Bid
Borrowing, the aggregate amount of the Advances then outstanding shall not
exceed the aggregate amount of the Commitments of the Lenders (computed without
regard to any Competitive Bid Reduction).

              (i) The Borrower may request a Competitive Bid Borrowing under
         this Section 2.03 by delivering to the Agent, by telecopier or telex, a
         notice of a Competitive Bid Borrowing (a "Notice of Competitive Bid
         Borrowing"), in substantially the form of Exhibit B-2 hereto,
         specifying therein the requested (v) date of such proposed Competitive
         Bid Borrowing, (w) aggregate amount of such proposed Competitive Bid
         Borrowing, (x) in the case of a Competitive Bid Borrowing consisting of
         LIBO Rate Advances, Interest Period, or in the case of a Competitive
         Bid Borrowing consisting of Fixed Rate Advances, maturity date for
         repayment of each Fixed Rate Advance to be made as part of such
         Competitive Bid Borrowing (which maturity date may not be earlier than
         the date occurring 7 days after the date of such Competitive Bid
         Borrowing or later than the earlier of (I) 180 days after the date of
         such Competitive Bid Borrowing and (II) the earlier of the Revolver
         Termination Date and the Term Loan Conversion Date), (y) interest
         payment date or dates relating thereto, and (z) other terms (if any) to
         be applicable to such Competitive Bid Borrowing, not later than 10:00
         A.M. (New York City time) (A) at least one Business Day prior to the
         date of the proposed Competitive Bid Borrowing, if the Borrower shall
         specify in the Notice of Competitive Bid Borrowing that the rates of
         interest to be offered by the Lenders shall be fixed rates per annum
         (the Advances comprising any such Competitive Bid Borrowing being
         referred to herein as "Fixed Rate Advances") and (B) at least five
         Business Days prior to the date of the proposed Competitive Bid
         Borrowing, if the Borrower shall instead specify in the Notice of
         Competitive Bid Borrowing that the rates of interest be offered by the
         Lenders are to be based on the LIBO Rate (the Advances comprising such
         Competitive Bid Borrowing being referred to herein as "LIBO Rate
         Advances"). Each Notice of Competitive Bid Borrowing shall be
         irrevocable and binding on the Borrower. The Agent shall in turn
         promptly notify each Lender of each request for a Competitive Bid
         Borrowing received by it from the Borrower by
<PAGE>   21


         sending such Lender a copy of the related Notice of Competitive Bid
         Borrowing.

              (ii) Each Lender may, if, in its sole discretion, it elects to do
         so, irrevocably offer to make one or more Competitive Bid Advances to
         the Borrower as part of such proposed Competitive Bid Borrowing at a
         rate or rates of interest specified by such Lender in its sole
         discretion, by notifying the Agent (which shall give prompt notice
         thereof to the Borrower), before 9:30 A.M. (New York City time) on the
         date of such proposed Competitive Bid Borrowing, in the case of a
         Competitive Bid Borrowing consisting of Fixed Rate Advances and before
         10:00 A.M. (New York City time) three Business Days before the date of
         such proposed Competitive Bid Borrowing, in the case of a Competitive
         Bid Borrowing consisting of LIBO Rate Advances, of the minimum amount
         and maximum amount of each Competitive Bid Advance which such Lender
         would be willing to make as part of such proposed Competitive Bid
         Borrowing (which amounts may, subject to the proviso to the first
         sentence of this Section 2.03(a), exceed such Lender's Commitment, if
         any), the rate or rates of interest therefor and such Lender's
         Applicable Lending Office with respect to such Competitive Bid Advance;
         provided that if the Agent in its capacity as a Lender shall, in its
         sole discretion, elect to make any such offer, it shall notify the
         Borrower of such offer at least 30 minutes before the time and on the
         date on which notice of such election is to be given to the Agent by
         the other Lenders. If any Lender shall elect not to make such an offer,
         such Lender shall so notify the Agent, before 10:00 A.M. (New York City
         time) on the date on which notice of such election is to be given to
         the Agent by the other Lenders, and such Lender shall not be obligated
         to, and shall not, make any Competitive Bid Advance as part of such
         Competitive Bid Borrowing; provided that the failure by any Lender to
         give such notice shall not cause such Lender to be obligated to make
         any Competitive Bid Advance as part of such proposed Competitive Bid
         Borrowing. (iii) The Borrower shall, in turn, before 10:30 A.M. (New
         York City time) on the date of such proposed Competitive Bid Borrowing,
         in the case of a Competitive Bid Borrowing consisting of Fixed Rate
         Advances and before 11:00 A.M. (New York City time) three Business Days
         before the date of such proposed Competitive Bid Borrowing, in the case
         of a Competitive Bid Borrowing consisting of LIBO Rate Advances,
         either:

                   (x) cancel such Competitive Bid Borrowing by giving the Agent
              notice to that effect, or

                   (y) accept one or more of the offers made by any Lender or
              Lenders pursuant to paragraph (ii) above, in its sole discretion,
              by giving notice to the Agent of the amount of each Competitive
              Bid Advance (which amount shall be equal to or greater than the
              minimum amount, and equal to or less than the maximum amount,
              notified to the Borrower by the Agent on behalf of such Lender for
              such Competitive Bid
<PAGE>   22


              Advance pursuant to paragraph (ii) above) to be made by each
              Lender as part of such Competitive Bid Borrowing, and reject any
              remaining offers made by Lenders pursuant to paragraph (ii) above
              by giving the Agent notice to that effect. The Borrower shall
              accept the offers made by any Lender or Lenders to make
              Competitive Bid Advances in order of the lowest to the highest
              rates of interest offered by such Lenders. If two or more Lenders
              have offered the same interest rate, the amount to be borrowed at
              such interest rate will be allocated among such Lenders in
              proportion to the amount that each such Lender offered at such
              interest rate.

              (iv) If the Borrower notifies the Agent that such Competitive Bid
         Borrowing is cancelled pursuant to paragraph (iii)(x) above, the Agent
         shall give prompt notice thereof to the Lenders and such Competitive
         Bid Borrowing shall not be made.

              (v) If the Borrower accepts one or more of the offers made by any
         Lender or Lenders pursuant to paragraph (iii)(y) above, the Agent shall
         in turn promptly notify (A) each Lender that has made an offer as
         described in paragraph (ii) above, of the date and aggregate amount of
         such Competitive Bid Borrowing and whether or not any offer or offers
         made by such Lender pursuant to paragraph (ii) above have been accepted
         by the Borrower, (B) each Lender that is to make a Competitive Bid
         Advance as part of such Competitive Bid Borrowing, of the amount of
         each Competitive Bid Advance to be made by such Lender as part of such
         Competitive Bid Borrowing, and (C) each Lender that is to make a
         Competitive Bid Advance as part of such Competitive Bid Borrowing, upon
         receipt, that the Agent has received forms of documents appearing to
         fulfill the applicable conditions set forth in Article III. Each Lender
         that is to make a Competitive Bid Advance as part of such Competitive
         Bid Borrowing shall, before 12:00 noon (New York City time) on the date
         of such Competitive Bid Borrowing specified in the notice received from
         the Agent pursuant to clause (A) of the preceding sentence or any later
         time when such Lender shall have received notice from the Agent
         pursuant to clause (C) of the preceding sentence, 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 portion of such
         Competitive Bid Borrowing. Upon fulfillment of the applicable
         conditions set forth in Article III and after receipt by the Agent of
         such funds, the Agent will make such funds available to the Borrower at
         the Agent's address referred to in Section 8.02. Promptly after each
         Competitive Bid Borrowing the Agent will notify each Lender of the
         amount of the Competitive Bid Borrowing, the consequent Competitive Bid
         Reduction and the dates upon which such Competitive Bid Reduction
         commenced and will terminate.

              (vi) If the Borrower notifies the Agent that it accepts one or
         more of the offers made by any Lender or Lenders pursuant to paragraph
         (iii)(y) above,

<PAGE>   23

         such notice of acceptance shall be irrevocable and binding on the
         Borrower. The Borrower shall 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 the related Notice of
         Competitive Bid Borrowing for such Competitive Bid Borrowing the
         applicable conditions set forth in Article III, 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 such Lender to fund the Competitive
         Bid Advance to be made by such Lender as part of such Competitive Bid
         Borrowing when such Competitive Bid Advance, as a result of such
         failure, is not made on such date.

         (b) Each Competitive Bid Borrowing shall be in an aggregate amount of
$5,000,000 or an integral multiple of $1,000,000 in excess thereof and,
following the making of each Competitive Bid Borrowing, the Borrower and each
Lender shall be in compliance with the limitations set forth in the proviso to
the first sentence of subsection (a) above.

         (c) Within the limits and on the conditions set forth in this Section
2.03, the Borrower may from time to time borrow under this Section 2.03, repay
or prepay pursuant to subsection (d) below, and reborrow under this Section
2.03, provided that a Competitive Bid Borrowing shall not be made within three
Business Days of the date of any other Competitive Bid Borrowing.

         (d) The Borrower shall repay to the Agent for the account of each
Lender that has made a Competitive Bid Advance, on the maturity date of each
Competitive Bid Advance (such maturity date being that specified by the Borrower
for repayment of such Competitive Bid Advance in the related Notice of
Competitive Bid Borrowing delivered pursuant to subsection (a)(i) above and
provided in the Competitive Bid Note evidencing such Competitive Bid Advance),
the then unpaid principal amount of such Competitive Bid Advance. The Borrower
shall have no right to prepay any principal amount of any Competitive Bid
Advance unless, and then only on the terms, specified by the Borrower for such
Competitive Bid Advance in the related Notice of Competitive Bid Borrowing
delivered pursuant to subsection (a)(i) above and set forth in the Competitive
Bid Note evidencing such Competitive Bid Advance.

         (e) The Borrower shall pay interest on the unpaid principal amount of
each Competitive Bid Advance from the date of such Competitive Bid Advance to
the date the principal amount of such Competitive Bid Advance is repaid in full,
at the rate of interest for such Competitive Bid Advance specified by the Lender
making such Competitive Bid Advance in its notice with respect thereto delivered
pursuant to subsection (a)(ii) above, payable on the interest payment date or
dates specified by the Borrower for such Competitive Bid Advance in the related
Notice of Competitive Bid Borrowing delivered pursuant to subsection (a)(i)
above, as provided in the Competitive Bid Note evidencing such Competitive Bid
Advance. Upon the occurrence and during

<PAGE>   24


the continuance of an Event of Default, the Borrower shall pay interest on the
amount of unpaid principal of and interest on each Competitive Bid Advance owing
to a Lender, payable in arrears on the date or dates interest is payable
thereon, at a rate per annum equal at all times to 2% per annum above the rate
per annum required to be paid on such Competitive Bid Advance under the terms of
the Competitive Bid Note evidencing such Competitive Bid Advance unless
otherwise agreed in such Competitive Bid Note.

         (f) The indebtedness of the Borrower resulting from each Competitive
Bid Advance made to the Borrower as part of a Competitive Bid Borrowing shall be
evidenced by a separate Competitive Bid Note of the Borrower payable to the
order of the Lender making such Competitive Bid Advance.

         (g) Upon delivery of each Notice of Competitive Bid Borrowing, the
Borrower shall pay a non-refundable fee of $3,000 to the Agent for its own
account.

              SECTION 2.04. Fees. (a) Facility Fee. The Borrower agrees to pay
to the Agent for the account of each Lender (other than the Designated Bidders)
a facility fee on the aggregate amount of such Lender's Commitment from the date
hereof in the case of each Initial Lender and from effective date specified in
the Assignment and Acceptance pursuant to which it became a Lender in the case
of each other Lender until the Maturity Date at a rate per annum equal to the
Applicable Percentage in effect from time to time, payable in arrears quarterly
on the last day of each March, June, September and December, and on the Maturity
Date.

         (b) Agent's Fees. The Borrower shall pay to the Agent for its own
account such fees as may from time to time be agreed between the Borrower and
the Agent.

              SECTION 2.05. Termination or Reduction of the Commitments. (a) If
the Borrower has not made the Term Loan Election at least 15 days prior to the
Revolver Termination Date, the Commitments shall be automatically terminated on
the Revolver Termination Date. If the Borrower has made the Term Loan Election
in accordance with Section 2.06, from time to time after the Term Loan
Conversion Date upon each prepayment of the Revolving Credit Advances, the
aggregate Commitments of the Lenders under this Agreement shall be automatically
and permanently reduced on a pro rata basis by an amount equal to the amount by
which the aggregate Commitments of the Lenders under this Agreement immediately
prior to such reduction exceeds the aggregate unpaid principal amount of the
Revolving Credit Advances outstanding at such time.

         (b) The Borrower shall have the right, upon at least three Business
Days' notice to the Agent, to terminate in whole or reduce ratably in part the
unused portions of the respective Commitments of the Lenders, provided that each
partial reduction shall be in the aggregate amount of $5,000,000 or an integral
multiple of $1,000,000 in excess thereof and provided further that the aggregate
amount of the Commitments of

<PAGE>   25


the Lenders shall not be reduced to an amount that is less than the aggregate
principal amount of the Competitive Bid Advances then outstanding.

              SECTION 2.06. Repayment of Revolving Credit Advances; Term Loan
Election. (a) The Borrower shall, subject to the next succeeding sentence, repay
to the Agent for the ratable account of the Lenders on the Revolver Termination
Date the aggregate principal amount of the Revolving Credit Advances then
outstanding.

         (b) The Borrower may, at any time prior to the Revolver Termination
Date and upon not less than 15 days' notice to the Agent, elect (the "Term Loan
Election") to convert all of the Revolving Credit Advances outstanding on the
date specified in such notice (the "Term Loan Conversion Date") into a term loan
which the Borrower shall repay in full to the Agent for the ratable account of
the Lenders on the Maturity Date; provided that no Default has occurred and is
continuing on the date of notice of the Term Loan Election or on the Term Loan
Conversion Date.

              SECTION 2.07. 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. Upon the occurrence and during the continuance of
an Event of Default, the Borrower shall pay interest on (i) 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

<PAGE>   26

Advance pursuant to clause (a)(i) or (a)(ii) above and (ii) 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 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 2.08. Interest Rate Determination. (a) Each Reference Bank
agrees to furnish to the Agent timely information for the purpose of determining
each Eurodollar Rate and each LIBO 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
2.07(a)(i) or (ii), and the rate, if any, furnished by each Reference Bank for
the purpose of determining the interest rate under Section 2.07(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 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 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 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 Advances into,
Eurodollar Rate Advances shall be suspended.
<PAGE>   27

         (f) If fewer than two Reference Banks furnish timely information to the
Agent for determining the Eurodollar Rate or LIBO Rate for any Eurodollar Rate
Advances or LIBO Rate Advances, as the case may be,

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

              (ii) with respect to Eurodollar Rate Advances, each such Advance
         will automatically, on the last day of the then existing Interest
         Period therefor, Convert into a Base Rate Advance (or if such 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 LIBO 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 2.09. 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 2.08 and
2.12, Convert all Revolving Credit Advances of one Type comprising the same
Borrowing into Revolving Credit Advances of the other Type; 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 Revolving Credit 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 Advance. Each notice of
Conversion shall be irrevocable and binding on the Borrower.

              SECTION 2.10. 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., (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 Revolving Credit Borrowing in whole or ratably in part,
together with accrued interest to the date of such
<PAGE>   28


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 principal amount outstanding 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 the
Securities and Exchange Commission under the Securities Exchange Act of 1934),
directly or indirectly, of Voting Stock of the Parent (or other securities
convertible into such Voting Stock) representing 20% or more of the combined
voting power of all Voting Stock of the Parent; 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
Parent.

              SECTION 2.11. 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 or LIBO Rate Advances
(excluding for purposes of this Section 2.11 any such increased costs resulting
from (i) Taxes or Other Taxes (as to which Section 2.14 shall govern) 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 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 (with a copy of such demand to the Agent), pay to the
Agent for the account of such Lender additional amounts sufficient to compensate
such Lender for such increased cost. A certificate as to the amount of such
increased cost, submitted to the Borrower and the Agent by such Lender, shall be
conclusive and binding for all purposes, absent manifest error.

         (b) If any Lender 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 any
corporation controlling such Lender and that the amount of such capital is
increased by or based upon the existence of such Lender's commitment to lend
hereunder and other commitments of this type, then, upon demand by such Lender
(with a copy of such demand to the
<PAGE>   29


Agent), the Borrower shall pay to the Agent for the account of such Lender, from
time to time as specified by such Lender, additional amounts sufficient to
compensate such Lender or such corporation in the light of such circumstances,
to the extent that such Lender reasonably determines such increase in capital to
be allocable to the existence of such Lender's commitment to lend hereunder. A
certificate as to such amounts submitted to the Borrower and the Agent by such
Lender 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 2.11, 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 Notes 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 2.12. 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 LIBO Rate Advances or
to fund or maintain Eurodollar Rate Advances or LIBO Rate Advances hereunder,
(i) each Eurodollar Rate Advance or LIBO Rate Advance, as the case may be, will
automatically, upon such demand, Convert into a Base Rate Advance or an Advance
that bears interest at the rate set forth in Section 2.07(a)(i), as the case may
be, and (ii) the obligation of the Lenders to make Eurodollar Rate Advances or
LIBO 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 2.13. 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. The Agent will promptly thereafter cause to be
distributed like funds relating to the payment of principal or interest or
facility fees ratably (other than amounts payable pursuant to Section 2.03,
2.11, 2.14 or 8.04(c)) to the Lenders for the account of their respective
Applicable Lending Offices, and like funds relating to the payment of any other
amount payable to any Lender to such Lender 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

<PAGE>   30


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, if and to the extent
payment owed to such Lender is not made when due hereunder or under the Note
held by such Lender, to charge from time to time against any or all of the
Borrower's accounts with such Lender 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 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 or
facility fees 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 or facility fee, as the case
may be; provided, however, that, if such extension would cause payment of
interest on or principal of Eurodollar Rate Advances or LIBO 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 2.14. Taxes. (a) Any and all payments by the Borrower
hereunder or under the Notes shall be made, in accordance with Section 2.13,
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 and the Agent, taxes
imposed on its overall net income, and

<PAGE>   31

franchise taxes imposed on it in lieu of net income taxes, by the jurisdiction
under the laws of which such Lender 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 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 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 2.14) such Lender 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.

         (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 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 2.14) 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 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

<PAGE>   32


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 forms 1001 or
4224, 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 compute the tax payable and
information required on the date hereof by Internal Revenue Service form 1001 or
4224, 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 2.14(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 2.14(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 2.14, 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 Notes held by such Lender
in accordance with Section 8.07, provided, however, that (i) no Default shall
have occurred and be continuing, (ii) the

<PAGE>   33


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 2.15. 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 Revolving Credit Advances owing to
it (other than pursuant to Section 2.11, 2.14 or 8.04(c)) in excess of its
ratable share of payments on account of the Revolving Credit Advances obtained
by all the Lenders, such Lender shall forthwith purchase from the other Lenders
such participations in the Revolving Credit Advances 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 2.15 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.

              SECTION 2.16. Extensions of Revolver Termination Date. No earlier
than 45 days and no later than 30 days prior to the Revolver Termination Date in
effect at any time, the Borrower may, by written notice to the Agent, request
that such Revolver Termination Date be extended for a period of 364 days. Such
request shall be irrevocable and binding upon the Borrower. The Agent shall
promptly notify each Lender of such request. If a Lender agrees, in its
individual and sole discretion, to so extend its Commitment (an "Extending
Lender"), it shall deliver to the Agent a written notice of its agreement to do
so no earlier than 30 days and no later than 20 days prior to such Revolver
Termination Date and the Agent shall notify the Borrower of such Extending
Lender's agreement to extend its Commitment no later than 15 days prior to such
Revolver Termination Date. The Commitment of any Lender that fails to accept or
respond to the Borrower's request for extension of the Revolver Termination Date
(a "Declining Lender") shall be terminated on the Revolver Termination Date
originally in effect (without regard to any extension by other Lenders) and on
such Revolver Termination Date the Borrower shall pay in full the principal
amount of all Advances owing to such Declining Lender, together with accrued
interest thereon to the date of such payment of principal and all other amounts
payable to such Declining Lender under this Agreement. The Agent shall promptly
notify each Extending Lender of the aggregate Commitments of the Declining
Lenders. The Extending Lenders, or any of

<PAGE>   34


them, may offer to increase their respective Commitments by an aggregate amount
up to the aggregate amount of the Declining Lenders' Commitments and any such
Extending Lender shall deliver to the Agent a notice of its offer to so increase
its Commitment no later than 15 days prior to such Revolver Termination Date. To
the extent of any shortfall in the aggregate amount of extended Commitments, the
Borrower shall have the right to require any Declining Lender to assign in full
its rights and obligations under this Agreement to an Eligible Assignee
designated by the Borrower and acceptable to the Agent, that agrees to accept
all of such rights and obligations (a "Replacement Lender"), provided that (i)
such increase and/or such assignment is otherwise in compliance with Section
8.07, (ii) such Declining Lender receives payment in full of the principal
amount of all Advances owing to such Declining Lender, together with accrued
interest thereon to the date of such payment of principal and all other amounts
payable to such Declining Lender under this Agreement, and (iii) any such
increase shall be effective on the Revolver Termination Date in effect at the
time the Borrower requests such extension and any such assignment shall be
effective on the date specified by the Borrower and agreed to by the Replacement
Lender and the Agent. If Extending Lenders and Replacement Lenders provide
Commitments in an aggregate amount at least equal to 51% of the aggregate amount
of the Commitments outstanding 30 days prior to the Revolver Termination Date in
effect at the time the Borrower requests such extension, the Revolver
Termination Date shall be extended by 364 days for such Extending Lenders.

              SECTION 2.17. Use of Proceeds. The proceeds of the Advances shall
be available (and the Borrower agrees that it shall use such proceeds) solely
for general corporate purposes of the Borrower and its Subsidiaries.


                                   ARTICLE III

                     CONDITIONS TO EFFECTIVENESS AND LENDING

         pending or threatened before any court, governmental agency or
         arbitrator that (i) could be reasonably likely to have a Material
         Adverse Effect other than the matters described in the SEC Reports (the
         "Disclosed Litigation") or (ii) purports to affect the legality,
         validity or enforceability of any Loan Document or the

              (c) Nothing shall have come to the attention of the Lenders during
         the course of their due diligence investigation to lead them to believe
         that the Information Memorandum was or has become misleading, incorrect
         or incomplete in any material respect; without limiting the generality
         of the foregoing, the Lenders shall have been given such access, as

         not acceptable to the Lenders) and shall remain in effect, and no law
         or regulation shall be applicable in the reasonable judgment of the
         Lenders that restrains, prevents or imposes materially adverse
         conditions upon the transactions contemplated by the Loan Documents.

              (e) The Borrower shall have notified each Lender and the Agent in
         writing as to the proposed Effective Date.

         fees contemplated in the Information Memorandum, and (ii) all facility

              finance the acquisition of such property) or extensions, renewals
              or replacements of any of the foregoing for the same or a lesser
              amount, provided, however, that no such Lien shall extend to or
              cover any properties of any character other than the real property

                   (iv) Liens on property of a Person existing at the time such
              Person is merged into or consolidated with the Borrower or any
              Subsidiary of the Borrower or becomes a Subsidiary of the
              Borrower; provided that such Liens were not created in

              other obligations related thereto) on any Debt of the Borrower
              (other than the Debt hereunder), provided that such Liens are
              granted in favor of one or more creditors under such Debt in order
              to secure the obligations of the Borrower thereunder, and

                   (vii) the replacement, extension or renewal of any Lien
              permitted by clause (iii), (iv) or (vi) above upon or in the same
              property theretofore subject thereto or the replacement, extension
              or renewal (without increase in the amount or change in any direct
              or contingent obligor) of the Debt secured thereby.

         failure shall continue after the applicable grace period, if any,
         specified in the agreement or instrument relating to such Debt; or any

         of an order for relief or the appointment of a receiver, trustee,
         custodian or other similar official for it or for any substantial part
         of its property and, in the case of any such proceeding instituted
         against it (but not instituted by it), either such proceeding shall
         remain undismissed or unstayed for a period of 30 days, or any of the
         actions sought in such proceeding (including, without limitation, the
         entry of an order for relief against, or the appointment of a receiver,

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 to make Advances to be terminated, whereupon the same
shall forthwith terminate, and (ii) shall at the request, or may with the
consent, of the Required Lenders, by notice to the Borrower, declare the Notes,
all interest thereon and all other amounts payable under this Agreement to be
forthwith due and payable, whereupon the Notes, 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; 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 to make Advances
shall automatically be terminated and (B) the Notes, all such interest and all

                                   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
Notes), 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, and such instructions shall be binding upon all Lenders
and all holders of Notes; 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 of any Note as the holder thereof until the Agent receives and accepts
an Assignment and Acceptance entered into by the Lender that is the payee of
such Note, 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



<PAGE>   50

selected 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. Citibank and Affiliates. With respect to its
Commitment, the Advances made by it and the Note issued to it, Citibank 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 Citibank in its
individual capacity. Citibank 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 Citibank 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 (other than the
Designated Bidders) agree to indemnify the Agent (to the extent not reimbursed
by the Borrower), ratably according to the respective principal amounts of the
Revolving Credit Notes then held by each of them (or if no Revolving Credit
Notes are at the time outstanding or if any Revolving Credit Notes are held by
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



<PAGE>   51

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 gross negligence or
willful misconduct. Without limitation of the foregoing, each Lender (other than
the Designated Bidders) 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.

              SECTION 8.01. Amendments, Etc. No amendment or waiver of any
provision of this Agreement or the Revolving Credit Notes, nor consent to any
departure by the Borrower therefrom, shall in any event be effective unless the
same shall be in writing and signed by the Required Lenders, and then such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given; provided, however, that no amendment, waiver

Lenders or subject the Lenders to any additional obligations, (c) reduce the

no amendment, waiver or consent shall, unless in writing and signed by the Agent
in addition to the Lenders required above to take such action, affect the rights
or duties of the Agent under this Agreement or any Note.

              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
or under any Note shall operate as a waiver thereof; nor shall any single or

thereof or the exercise of any other right. The remedies herein provided are
cumulative and not exclusive of any remedies provided by law.

              SECTION 8.04. Costs and Expenses. (a) The Borrower agrees to pay

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

         (b) The Borrower agrees to indemnify, to the extent legally
permissible, and hold harmless the Agent 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

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. The Borrower also agrees not to assert any claim against
the Agent, 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 of the transactions contemplated herein or therein or the actual or proposed
use of the proceeds of the Advances.

         (c) If any payment of principal of, or Conversion of, any Eurodollar
Rate Advance or LIBO 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 Advance,
as a result of a payment or Conversion pursuant to Section 2.08(d) or (e), 2.10
or 2.12, acceleration of the maturity of the Notes 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 Advance.

         (d) Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of each Loan Party contained
in Sections 2.11, 2.14 and 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 Notes due and payable pursuant to the provisions of Section 6.01,
each Lender 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 or such
Affiliate to or for the credit or the account of either Loan Party against any
and all of the obligations of either Loan Party now or hereafter existing under
the Loan Documents Agreement and the Note held by such Lender, whether or not
such Lender shall have made any demand under this Agreement or such Note and
although such obligations may be unmatured. Each Lender agrees promptly to
notify such Loan Party 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 and its Affiliates under this Section are
in addition to other rights and remedies (including, without limitation, other
rights of set-off) that such Lender and its Affiliates may have.

              SECTION 8.06. Binding Effect. This Agreement shall become
effective (other than Sections 2.01 and 2.03, which shall only become effective
upon


<PAGE>   55

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 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.

              SECTION 8.07. Assignments, Designations and Participations. (a)
Each Lender (other than the Designated Bidders) may 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
Revolving Credit Advances owing to it and the Revolving Credit Note or Notes
held by it); provided, however, that (i) each such assignment shall be of a
constant, and not a varying, percentage of all rights and obligations under this
Agreement (other than any right to make Competitive Bid Advances, Competitive
Bid Advances owing to it and Competitive Bid Notes), (ii) 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 (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, (iii) each
such assignment shall be to an Eligible Assignee, and (iv) 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
Revolving Credit 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, (x) 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 (y) 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,


<PAGE>   56



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 Revolving Credit 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 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 its receipt of such notice, the Borrower, at its own expense, shall
execute and deliver to the Agent in exchange for the surrendered Revolving
Credit 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, a new Revolving
Credit Note to the order of the assigning Lender in an amount equal to the
Commitment retained by it hereunder. Such new Revolving Credit Note or Notes
shall be in an aggregate principal amount equal to the aggregate principal
amount of such surrendered Revolving Credit 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-1 hereto.

         (d) Each Lender (other than the Designated Bidders) may designate one
or more banks or other entities to have a right to make Competitive Bid Advances
as a Lender pursuant to Section 2.03; provided, however, that (i) no such Lender
shall be entitled to make more than two such designations, (ii) each such Lender
making one or more of such designations shall retain the right to make
Competitive Bid Advances as a Lender pursuant to Section 2.03, (iii) each such
designation shall be to a Designated Bidder and (iv) the parties to each such
designation shall execute and deliver to the Agent, for its acceptance and
recording in the Register, a Designation Agreement.


<PAGE>   57

Upon such execution, delivery, acceptance and recording, from and after the
effective date specified in each Designation Agreement, the designee thereunder
shall be a party hereto with a right to make Competitive Bid Advances as a
Lender pursuant to Section 2.03 and the obligations related thereto.

         (e) By executing and delivering a Designation Agreement, the Lender
making the designation thereunder and its designee thereunder confirm and agree
with each other and the other parties hereto as follows: (i) such 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 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 designee
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 Designation Agreement; (iv) such designee will,
independently and without reliance upon the Agent, such designating 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 designee confirms that it is a
Designated Bidder; (vi) such designee 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 designee agrees that it will perform in accordance with their terms all of
the obligations which by the terms of this Agreement are required to be
performed by it as a Lender.

         (f) Upon its receipt of a Designation Agreement executed by a
designating Lender and a designee representing that it is a Designated Bidder,
the Agent shall, if such Designation Agreement has been completed and is
substantially in the form of Exhibit D hereto, (i) accept such Designation
Agreement, (ii) record the information contained therein in the Register and
(iii) give prompt notice thereof to the Borrower.

         (g) The Agent shall maintain at its address referred to in Section 8.02
a copy of each Assignment and Acceptance and each Designation Agreement
delivered to and accepted by it and a register for the recordation of the names
and addresses of the Lenders and, with respect to Lenders other than Designated
Bidders, the Commitment of, and principal amount of the Advances 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


<PAGE>   58

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.

         (h) 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 Advances owing to it and the
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 holder of any such Note 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 reduce the principal of, or interest on, the Notes or
any fees or other amounts payable hereunder, 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 Notes or any fees or other amounts payable hereunder, in
each case to the extent subject to such participation.

         (i) 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.

         (j) Notwithstanding any other provision set forth in this Agreement,
any Lender may at any time create a security interest in all or any portion of
its rights under this Agreement (including, without limitation, the Advances
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.

              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(i), to actual or prospective assignees and
participants, and then only on a


<PAGE>   59


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 either Loan Party
received by it from such Lender and (d) as requested or required by any state,
federal or foreign authority or examiner regulating banks or banking.

              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 City, 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. Effective Date. As of the Effective Date, (i) the
Original Credit Agreement is amended and restated in full as set forth in this
Agreement, (ii) the Commitments (including the Existing Commitments) are
restated as set forth in the signature pages hereof, (iii) the Existing Notes
are cancelled and


<PAGE>   60

replaced by the Notes, and (iv) all obligations which, by the terms of the
Original Credit Agreement, are evidenced by the Existing Notes are evidenced by
the Notes.

              SECTION 8.13. Waiver of Jury Trial. Each of the Borrower, the
Agent 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 or any Lender in the negotiation, administration,
performance or enforcement thereof.

         THIS SUPPORT AGREEMENT, dated as of January 19, 1999, is between DTE
ENERGY COMPANY, a Michigan corporation ("PARENT"), and DTE CAPITAL CORPORATION,
a Michigan corporation ("SUBSIDIARY").

         WHEREAS, Parent is the owner of 100% of the outstanding common stock of
Subsidiary;

         WHEREAS, Subsidiary intends from time to time to make borrowings from
the lenders party to the Second Amended and Restated $400,000,000 Credit
Agreement (such agreement as it may be amended and in effect from time to time,
the "CREDIT AGREEMENT"), dated as of January 19, 1999 among the Subsidiary, the
lenders party thereto and Citibank, N.A. as Administrative Agent (such lenders
and the Administrative Agent being hereinafter collectively referred to as the
"LENDERS"), and to issue debt securities to the Lenders pursuant to the Credit
Agreement (such borrowings and debt securities, including without limitation all
interest, fees, expenses and other amounts payable in accordance with the
documentation relating to such borrowings and debt securities being hereinafter
collectively referred to as "DEBT");

         WHEREAS, Parent and Subsidiary desire to take certain actions to
enhance and maintain the financial condition of Subsidiary as hereinafter set
forth in order to enable Subsidiary and its subsidiaries to incur indebtedness
on more advantageous and reasonable terms; and

         WHEREAS, the Lenders will rely upon this Agreement in making loans or
extending credit to Subsidiary;

         NOW, THEREFORE, in consideration of the premises, and other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties hereto agree as follows:

1.            SECTION STOCK OWNERSHIP. During the term of this Agreement, Parent
will own all of the voting common stock of Subsidiary and The Detroit Edison
Company ("DECO") now or hereafter issued and outstanding.

1.            SECTION NEGATIVE PLEDGE. During the term of this Agreement, Parent
will not create or suffer to exist any lien, security interest or other charge
of encumbrance, upon or with respect to any voting common stock of DECO from
time to time owned by Parent or any capital stock of Subsidiary from time to
time owned by Parent, provided, however, that any restriction on the payment of
dividends by DECO or Subsidiary contained in any subordinated debt instrument,
preferred stock or preference stock of








                       SIGNATURE PAGE TO CREDIT AGREEMENT
<PAGE>   106


DECO or Subsidiary shall not constitute a lien, security interest or other
charge or encumbrance.

1.            SECTION LIQUIDITY PROVISION. If, during the term of this
Agreement, Subsidiary is unable to make timely payment of interest, principal or
premium, if any, on any Debt owing to any Lender by Subsidiary, Parent promptly
shall provide to Subsidiary, at its request, such funds (in the form of cash or
liquid assets) in an amount sufficient to permit Subsidiary to make timely
payment in respect of such Debt as equity or as a loan, as Parent shall
determine in its sole discretion. If such funds are advanced to Subsidiary as a
loan, such loan shall be on such terms and conditions, including maturity and
rate of interest, as Parent and Subsidiary shall agree. Notwithstanding the
foregoing, any such loan shall be subordinated to any and all Debt of Subsidiary
owing to any Lender to the extent and in the manner set forth in Section 7
below. Each of the parties hereto acknowledges that Parent's obligations
hereunder do not constitute a guarantee by Parent of Debt of the Subsidiary.

1.            SECTION WAIVERS. Parent hereby waives any failure or delay on the
part of Subsidiary in asserting or enforcing any of its rights or in making any
claims or demands hereunder. Subsidiary or any Lender may at any time, without
Parent's consent, without notice to Parent and without affecting or impairing
Subsidiary's or such Lender's rights or Parent's obligations hereunder, do any
of the following with respect to any Debt: (a) make changes modifications,
amendments or alterations, by operation of law or otherwise, including, without
limitation, any increase in the principal amount of such Debt or the rate of
interest payable thereon or any changes in the method of calculating the rate of
interest payable thereon, (b) grant renewals and extensions and extensions of
time, for payment or otherwise, (c) accept new or additional documents,
instruments or agreements relating to or in substitution of said Debt, or (d)
otherwise handle the enforcement of their respective rights and remedies in
accordance with their business judgment.

1.            SECTION AMENDMENT, SUSPENSION. This Agreement may be amended or
terminated at any time by written amendment or agreement signed by both parties;
provided, however, that except as set forth in the next succeeding sentence, no
amendment to the Agreement which adversely affects the rights of Subsidiary or
any Lender and no termination of this Agreement shall be effective as to
Subsidiary or any Lender until such time as all Debt owing to such Lender by
Subsidiary on the date of such amendment or termination shall have been paid in
full and such Lender's Commitment (as defined in the Credit Agreement) shall
have been terminated, unless such Lender shall consent in writing to the
contrary. Notwithstanding the foregoing, Parent's obligations under this
Agreement shall be suspended and shall be of no force and effect as to the
parties hereto and as to all Lenders if and for so long as (i) Subsidiary shall
have (A) a long-term debt rating of not less than "A-" from Standard & Poor's
Corporation or its successor ("S&P) or a long-term debt rating of not less than
"A3" from Moody's Investors Service or its successor ("MOODY'S") or (B) a
short-term debt rating of not less that "A-2" from S&P or a short-term debt
rating of not less than "Prime-2" from










                       SIGNATURE PAGE TO CREDIT AGREEMENT
<PAGE>   107

Moody's and (ii) Parent shall have submitted a written request to the Subsidiary
that its obligations under this Agreement be so suspended (with a copy to the
Administrative Agent) and shall not have revoked such request in writing. Parent
covenants that it will revoke any such request to the extent that the suspension
of Parent's obligations under this Agreement has an adverse effect on any debt
rating of Subsidiary. For purposes of this Section 5, ratings shall be based
upon unsecured non-credit enhanced debt of Subsidiary.

1.            SECTION RIGHTS OF LENDER. Subsidiary hereby assigns and pledges to
the Lenders, for the ratable benefit of each Lender, Subsidiary's rights under
Sections 1, 2, 3 and 4 of this Agreement, and, if Subsidiary fails or refuses to
take timely action to enforce its rights under Section 1, 2, 3 or 4 of this
Agreement, any Lender may enforce such rights on behalf of Subsidiary directly
against Parent. Parent hereby consents to such assignment and pledge. This
assignment and pledge secures all obligations of Subsidiary under the Credit
Agreement and the Notes (as defined in the Credit Agreement). Subsidiary and
Parent agree, for the benefit of the Lenders, to execute and deliver all further
instruments and documents, and take all further action, that Lenders may request
in order to perfect and protect any security interest purported to be granted
hereby or to enable the Lenders to enforce their rights and remedies hereunder.

1.            SECTION SUBORDINATION. All loans made by Parent to Subsidiary
pursuant to Section 3 hereof (the "SUBORDINATED LOANS") shall be subordinate and
junior in right of payment to the prior payment in full of all Debt from time to
time outstanding owing to ally Lender, to the extent and in the manner provided
below:

a)                 Unless and until all Debt owing to the Lenders shall have
been paid in full and the Commitments shall have been terminated:

(1)                Parent will not sell, assign or otherwise transfer any claim
against Subsidiary in respect of any Subordinated Loan unless such transfer is
made expressly subject to this Agreement and the transferee shall execute an
instrument whereby the transferee agrees to be bound by the provisions of this
Section 7;

(1)                Subsidiary will not make, and Parent will not demand, accept
or receive, any direct or indirect payment (in cash, property, by set-off or
otherwise) of or on account of any Subordinated Loan, and no such payment shall
be due, except that nothing contained in this Section 7(a) shall prevent
Subsidiary from making, or Parent from accepting and receiving, any payment on
account of Subordinated Loans, if there is not then in existence a default by
Subsidiary under the Credit Agreement or the Notes (as defined in the Credit
Agreement) or a default by Parent under this Agreement.

a)                 In the event of (x) any insolvency, bankruptcy, receivership,
liquidation, reorganization, readjustment, composition or other similar
proceeding relative to Subsidiary or its creditors of its property, or (y) any
proceeding for the voluntary liquidation, dissolution or other winding up of
subsidiary, whether or not

involving insolvency or bankruptcy proceedings, or (z) any assignment for the
benefit of creditors or other marshalling of the assets of Subsidiary, then and
in any such event:

(1)                all Debt owing to the Lenders shall be paid in full before
any payment or distribution of any character (whether in cash, securities or
other property) shall be made in respect of any Subordinated Loans;

(1)                any payment or distribution of any character (whether in
cash, securities or other property) which would otherwise (but for the
provisions of this Section 7) be payable or deliverable in respect of any
Subordinated Loan shall be paid or delivered directly to the Lenders until all
Debt owing to the Lenders shall have been paid in full;

(1)                Parent irrevocably authorizes and empowers the Lenders to
demand, sue for, collect and receive any such payment or distribution and to
receipt therefor and to file all such claims and take all such other action, in
the name of Parent or the Lenders or otherwise, as the Lenders may determine to
be necessary or appropriate for the enforcement of the provisions of this
Section 7 (Parent hereby agreeing to execute and deliver to the Lenders such
further instruments confirming such authorization and such powers of attorney,
proofs of claim, assignments of claim and other instruments as may be requested
by the Lenders in order to enable them to enforce any and all claims with
respect to any Subordinated Loans); and

Debt owing to the Lenders shall have been paid in full.

a)                 Until all Debt shall be paid in full, Parent hereby defers
all rights of subrogation in respect of any payment of Debt made by Parent. Upon
payments in full of Debt owing to Lenders, Parent shall be subrogated to the
rights of Lenders to receive any further payment or distributions in respect of
Debt, provided, however, that nothing in this Section 7(c) will prohibit the
Parent from receiving any payments permitted under Section 7(a)(ii).

a)                 Notwithstanding anything contained in this Section 7, the
Parent shall have the right to loan up to $1,200,000,000 to the Subsidiary
pursuant to one or more "make-well", "keep-well" or support agreements, which
loans may be pari passu in right of payment with the payment in full of all Debt
from time to time outstanding owing to any Lender.

                                                            ASSIGNMENT AGREEMENT

         COLLATERAL ASSIGNMENT AGREEMENT dated as of January 19, 1999, made by
DTE CAPITAL CORPORATION, a Michigan corporation (the "GRANTOR"), to CITIBANK,
N.A. ("CITIBANK"), as agent (the "AGENT") for the banks (the "LENDERS") parties
to the Credit Agreement (as hereinafter defined).

                             PRELIMINARY STATEMENTS

         (1) The Lenders and the Agent have entered into a Second Amended and
Restated Credit Agreement dated as of January 19, 1999 (said Agreement, as it
may hereafter be amended or otherwise modified from time to time, being the
"CREDIT AGREEMENT") with the Grantor, as borrower and Salomon Smith Barney Inc.,
as arranger. Terms defined in the Credit Agreement and not otherwise defined
herein are used herein as therein defined.

         (2) It is a condition precedent to the making of Advances by the
Lenders under the Credit Agreement that the Grantor shall have granted the
assignment and security interest contemplated by this Agreement.

         NOW, THEREFORE, in consideration of the premises and in order to induce
the Lenders to make Advances under the Credit Agreement, the Grantor hereby
agrees with the Agent for its benefit and the ratable benefit of the Lenders as
follows:

1.            SECTION COLLATERAL ASSIGNMENT. The Grantor hereby assigns to the
Agent for its benefit and the ratable benefit of the Lenders, and hereby grants
to the Agent for its benefit and the ratable benefit of the Lenders a security
interest in, all of the Grantor's right, title and interest in and to the
following (the "COLLATERAL"): the Support Agreement as it may be amended or
otherwise modified from time to time (the "ASSIGNED AGREEMENT"), including,
without limitation, (i) all rights of the Grantor to receive moneys due and to
become due under or pursuant to the Assigned Agreement, (ii) all rights of the
Grantor to receive proceeds of any insurance, indemnity, warranty or guaranty
with respect to the Assigned Agreement, (iii) claims of the Grantor for damages
arising out of or for breach of or default under the Assigned Agreement, (iv)
the right of the Grantor to terminate the Assigned Agreement, to perform
thereunder and to compel performance and otherwise exercise all remedies
thereunder, and (iv) all proceeds of any and all of the foregoing Collateral.

1.            SECTION SECURITY FOR OBLIGATIONS. This Agreement secures the
payment of all obligations of the Borrower now or hereafter existing under the
Credit Agreement and the Notes, whether for principal, interest, fees, expenses
or otherwise, and all obligations of the Grantor now or hereafter existing under
this Agreement (all such obligations of the Borrower and the Grantor being the
"OBLIGATIONS"). Without limiting the generality of the foregoing, this Agreement
secures the payment of all amounts which constitute part of the Obligations and










                       SIGNATURE PAGE TO CREDIT AGREEMENT
<PAGE>   111


would be owed by the Borrower to the Agent or the Lenders under the Credit
Agreement and the Notes but for the fact that they are unenforceable or not
allowable due to the existence of a bankruptcy, reorganization or similar
proceeding involving the Borrower.

1.            SECTION GRANTOR REMAINS LIABLE. Anything herein to the contrary
notwithstanding, (a) the Grantor shall remain liable under the contracts and
agreements included in the Collateral to the extent set forth therein to perform
all of its duties and obligations thereunder to the same extent as if this
Agreement had not been executed, (b) the exercise by the Agent of any of the
rights hereunder shall not release the Grantor from any of its duties or
obligations under the contracts and agreements included in the Collateral, and
(c) neither the Agent nor any Bank shall have any obligation or liability under
the contracts and agreements included in the Collateral by reason of this
Agreement, nor shall the Agent or any Bank be obligated to perform any of the
obligations or duties of the Grantor thereunder or to take any action to collect
or enforce any claim for payment assigned hereunder.

1.            SECTION REPRESENTATIONS AND WARRANTIES. The Grantor represents and
warrants as follows:

a)                 The Assigned Agreement, a true and complete copy of which has
been furnished to each Bank, has been duly authorized, executed and delivered by
all parties thereto, has not been amended or otherwise modified except as
permitted by Section 7, is in full force and effect and is binding upon and
enforceable against all parties thereto in accordance with its terms. There
exists no default under the Assigned Agreement by any party thereto.

a)                 The chief place of business and chief executive office of the
Grantor and the office where the Grantor keeps its records concerning the
Collateral are located at its address specified in Section 15. None of the
Collateral is evidenced by a promissory note or other instrument (it being
understood that the Assigned Agreement does not constitute a promissory note or
other instrument).

a)                 The Grantor is the legal and beneficial owner of the
Collateral free and clear of any lien, security interest, option or other charge
or encumbrance except for the security interest created by this Agreement. No
effective financing statement or other document similar in effect covering all
or any part of the Collateral is on file in any recording office, except such as
may have been filed in favor of the Agent relating to this Agreement. The
Grantor has no trade names.

a)                 This Agreement creates a valid and perfected first priority
security interest in the Collateral, securing the payment of the Obligations,
and all filings and other actions necessary or desirable to perfect and protect
such security interest have been duly taken.

<PAGE>   112


a)                 No consent of any other person or entity and no
authorization, approval or other action by, and no notice to or filing with, any
governmental authority or regulatory body is required (i) for the grant by the
Grantor of the assignment and security interest granted hereby or for the
execution, delivery or performance of this Agreement by the Grantor, (ii) for
the perfection or maintenance of the assignment and security interest created
hereby (including the first priority nature of such assignment and security
interest) or (iii) for the exercise by the Agent of its rights and remedies
hereunder.

a)                 There are no conditions precedent to the effectiveness of
this Agreement that have not been satisfied or waived.

a)                 The Grantor has, independently and without reliance upon the
Agent or any Bank and based on such documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Agreement.

a)            SECTION FURTHER ASSURANCES. The Grantor agrees that from time
to time, at the expense of the Grantor, the Grantor will promptly execute and
deliver all further instruments and documents, and take all further action, that
may be necessary or desirable, or that the Agent may reasonably request, in
order to perfect and protect the assignment and security interest granted or
purported to be granted hereby or to enable the Agent to exercise and enforce
its rights and remedies hereunder with respect to any Collateral. Without
limiting the generality of the foregoing, the Grantor will execute and file such
financing or continuation statements, or amendments thereto, and such other
instruments or notices, as may be necessary or desirable, or as the Agent may
reasonably request, in order to perfect and preserve the assignment and security
interest granted or purported to be granted hereby.

a)                 The Grantor hereby authorizes the Agent to file one or more
financing or continuation statements, and amendments thereto, relating to all or
any part of the Collateral without the signature of the Grantor where permitted
by law. A photocopy or other reproduction of this Agreement or any financing
statement covering the Collateral or any part thereof shall be sufficient as a
financing statement where permitted by law.

1.            SECTION PLACE OF PERFECTION; RECORDS. The Grantor shall keep its
chief place of business and chief executive office and the office where it keeps
its records concerning the Collateral at the location therefor specified in
Section 4(b) or, upon 30 days' prior written notice to the Agent, at any other
locations in a jurisdiction where all action required by Section 5 shall have
been taken with respect to the Collateral. The Grantor will hold and preserve
such records and will permit representatives of the Agent at any time during
normal business hours to inspect and make abstracts from such records.

reasonably requested by the Agent.

(1)                furnish to the Agent promptly upon receipt thereof copies of
all notices, requests and other documents received by the Grantor under or
pursuant to the Assigned Agreement, and from time to time (A) furnish to the
Agent such information and reports regarding the Collateral as the Agent may
reasonably request and (B) upon request of the Agent make to any other party to
the Assigned Agreement such demands and requests for information and reports or
for action as the Grantor is entitled to make thereunder.

create or permit to exist any lien, security interest, option or other charge or
encumbrance upon or with respect to any of the Collateral, except for the
assignment and security interest under this Agreement;

consent, waiver or approval thereunder; or

(1)                waive any default under or breach of the Assigned Agreement;
or

(1)                take any other action in connection with the Assigned
Agreement which would impair the value of the interest or rights of the Grantor
thereunder or which would impair the interest or rights of the Agent.

a)            SECTION PAYMENTS UNDER THE ASSIGNED AGREEMENT. The Grantor agrees,
and has effectively so instructed the Parent that upon the occurrence and during
the continuance of an Event of Default, all payments due or to become due under

a)                 Except as set forth in Section 12, all moneys received or
collected pursuant to subsection (a) above shall be applied to all or any part
of the Obligations as the Agent may elect.

1.            SECTION AGENT APPOINTED ATTORNEY-IN-FACT. The Grantor hereby
appoints the Agent the Grantor's attorney-in-fact, with full authority in the
place and stead of the Grantor and in the name of the Grantor or otherwise, from
time to time in the Agent's discretion to take any action and to execute any
instrument which the Agent may deem necessary or advisable to accomplish the
purposes of this Agreement, including, without limitation:

a)                 to ask, demand, collect, sue for, recover, compromise,
receive and give acquittance and receipts for moneys due and to become due under
or in connection with the Collateral,

proceedings which the Agent may deem necessary or desirable for the collection
of any of the Collateral or otherwise to enforce compliance with the terms and
conditions of the Assigned Agreement or the rights of the Agent with respect to
any of the Collateral.

1.            SECTION AGENT MAY PERFORM. If the Grantor fails to perform any
agreement contained herein, the Agent may itself perform, or cause performance
of, such agreement, and the expenses of the Agent incurred in connection
therewith shall be payable by the Grantor under Section 13(b).

1.            SECTION THE AGENT'S DUTIES. The powers conferred on the Agent
hereunder are solely to protect its interest in the Collateral and shall not
impose any duty upon it to exercise any such powers. Except for the safe custody
of any Collateral in its possession and the accounting for moneys actually
received by it hereunder, the Agent shall have no duty as to any Collateral or
as to the taking of any necessary steps to preserve rights against any parties
or any other rights pertaining to any Collateral. The Agent shall be deemed to
have exercised reasonable care in the custody and preservation of any Collateral
in its possession if such Collateral is accorded treatment substantially equal
to that which Citibank accords its own property.

funds of the Grantor and shall be forthwith paid over to the Agent in the same
form as so received (with any necessary indorsement).

a)                 All payments made under or in connection with the Assigned
Agreement or otherwise in respect of the Collateral, and all cash proceeds in
respect of any sale of, collection from, or other realization upon all or any
part of the Collateral, received by the Agent may, in the discretion of the
Agent, be held by the Agent as collateral for, and/or then or at any time
thereafter applied (after payment of any amounts payable to the Agent pursuant
to Section 13) in whole or in part by the Agent for the ratable benefit of the
Lenders against, all or any part of the Obligations in such order as the Agent
shall elect. Any surplus of such payments or cash proceeds held by the Agent and
remaining after payment in full of all the Obligations shall be paid over to the
Grantor or to whomsoever may be lawfully entitled to receive such surplus.

a)                 The Agent may exercise in respect of the Collateral, in
addition to other rights and remedies provided for herein or otherwise available
to it, all the rights and remedies of a secured party on default under the
Uniform Commercial Code in effect in the State of New York at that time (the
"CODE") (whether or not the Code applies to the affected Collateral).

a)            SECTION INDEMNITY AND EXPENSES. The Grantor agrees to indemnify
the Agent from and against any and all claims, losses and liabilities (including
reasonable attorneys' fees) growing out of or resulting from this Agreement

losses or liabilities resulting from the Agent's gross negligence or willful
misconduct.

a)                 The Grantor will upon demand pay to the Agent the amount of

connection with (i) the administration of this Agreement, (ii) the custody or
preservation of, or the sale of, collection from or other realization upon, any
of the Collateral, (iii) the exercise or










                       SIGNATURE PAGE TO CREDIT AGREEMENT

enforcement of any of the rights of the Agent or the Lenders hereunder or (iv)
the failure by the Grantor to perform or observe any of the provisions hereof.

1.            SECTION AMENDMENTS; ETC. No amendment or waiver of any provision
of this Agreement, and no consent to any departure by the Grantor herefrom shall
in any event be effective unless the same shall be in writing and signed by the
Agent, and then such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given.

1.            SECTION ADDRESSES FOR NOTICES. All notices and other
communications provided for hereunder shall be in writing (including telecopier,

1.            SECTION CONTINUING ASSIGNMENT AND SECURITY INTEREST; ASSIGNMENTS
UNDER CREDIT AGREEMENT. This Agreement shall create a continuing assignment of
and security interest in the Collateral and shall (i) remain in full force and
effect until the later of (x) the payment in full of the Obligations and all
other amounts payable under this Agreement and (y) the expiration or termination
of the Commitments, (ii) be binding upon the Grantor, its successors and
assigns, and (iii) inure, together with the rights and remedies of the Agent
hereunder, to the benefit of the Agent, the Lenders and their respective
successors, transferees and assigns. Without limiting the generality of the
foregoing clause (iii), any Bank may assign or otherwise transfer all or any
portion of its rights and obligations under the Credit Agreement (including,
without limitation, all or any portion of its Commitment, the Advances owing to
it and any Note held by it) held by it to any other person or entity, and such
other person or entity shall thereupon become vested with all the benefits in
respect thereof granted to such Bank herein or otherwise, subject, however, to
the provisions of Article VI (concerning the Agent) of the Credit Agreement.
Upon the later of the payment in full of the Obligations and all other amounts
payable under this Agreement and the expiration or termination of the
Commitments, the security interest granted hereby shall terminate and all rights
to the Collateral shall revert to the Grantor. Upon any such termination, the
Agent will, at the Grantor's expense, execute and deliver to the Grantor such
documents as the Grantor shall reasonably request to evidence such termination.

1.            SECTION GOVERNING LAW; TERMS. This Agreement shall be governed by
and construed in accordance with the laws of the State of New York, except to
the extent that the validity or perfection of the assignment and security
interest hereunder, or remedies hereunder, in respect of any particular
Collateral are governed by the laws

<PAGE>   117

of a jurisdiction other than the State of New York. Unless otherwise defined
herein or in the Credit Agreement, terms used in Article 9 of the Code are used
herein as therein defined.

         IN WITNESS WHEREOF, the Grantor has caused this Agreement to be duly
executed and delivered by its officer thereunto duly authorized as of the date
first above written.

(ii)               Acknowledgment copies or stamped receipt copies of the UCC-1
financial statement filed by the Agent in connection with the Original Credit
Agreement and any amendments thereto (the "UCC FILINGS") under the Uniform
Commercial Code as in effect the State of Michigan (the "UCC"), naming the
Borrower as debtor and the Agent as secured party, which UCC Filings have been
filed in the filing offices listed in Schedule 1 hereto.

I have also examined the originals, or copies certified to my satisfaction, of
the documents listed in a certificate of a Financial Officer of each Loan Party,
dated the date hereof (the "CERTIFICATES"), 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 any Loan Party's obligations under the Loan Documents to
which it is party. In addition, I have examined the originals, copies certified
to my satisfaction, of such other corporate records of each Loan Party,
certificates of public officials and of officers of each Loan Party, and
agreements, instruments and other documents, as we 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
Initial 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.                 Each Loan Party is a corporation duly organized, validly
existing and in good standing under the laws of the State of Michigan.

1.                 The execution, delivery and performance by each Loan Party of
the Loan Documents to which it is party, and the consummation of the
transactions contemplated thereby, are within such Loan Party's corporate
powers, have been duly authorized by all necessary corporate action, and do not
contravene (i) the Charters or the By-Laws of such Loan Party or (ii) any law,
rule or regulation applicable to such Loan Party (including, without limitation,

contained in any document listed in the Certificates or, to the best of my
knowledge (after due inquiry), contained in any other similar document.

1.                 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 (i) the due execution, delivery, recordation, filing
or performance by the Loan Parties of the Loan Documents to which each is a
party, and (ii) the grant by the Borrower of the security interest granted by it
pursuant to the Assignment Agreement.

1.                 Each Loan Document has been duly executed and delivered on
behalf of each Loan Party thereto.

1.                 Except as may have been disclosed to you in the SEC Reports,
to the best of my knowledge (after due inquiry) there are no pending or overtly
threatened actions or proceedings affecting any Loan Party or any of their
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.

1.                 If, despite the provisions of Section 8.09 of the Credit
Agreement, Section 17 of the Collateral Assignment Agreement and Section 10 of
the Support 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 Loan
Documents would be, under the laws of the State of Michigan, legal, valid and
binding obligations of each Loan Party thereto enforceable against such Loan
Party in accordance with their respective terms.

1.                 The Collateral Assignment Agreement creates a valid first
priority security interest in the Assigned Rights, securing the payment of the
Obligations. The UCC Filings are in appropriate form and have been filed
pursuant to the UCC, resulting in the perfection of such security interest in
the Assigned Rights.

                         COLLATERAL ASSIGNMENT AGREEMENT


         COLLATERAL ASSIGNMENT AGREEMENT dated as of January 19, 1999, made by
DTE CAPITAL CORPORATION, a Michigan corporation (the "GRANTOR"), to CITIBANK,
N.A. ("CITIBANK"), as agent (the "AGENT") for the banks (the "LENDERS") parties
to the Credit Agreement (as hereinafter defined).

                             PRELIMINARY STATEMENTS

         (1) The Lenders and the Agent have entered into a Second Amended and
Restated Credit Agreement dated as of January 19, 1999 (said Agreement, as it
may hereafter be amended or otherwise modified from time to time, being the
"CREDIT AGREEMENT") with the Grantor, as borrower and Salomon Smith Barney Inc.,
as arranger. Terms defined in the Credit Agreement and not otherwise defined
herein are used herein as therein defined.

         (2) It is a condition precedent to the making of Advances by the
Lenders under the Credit Agreement that the Grantor shall have granted the
assignment and security interest contemplated by this Agreement.

         NOW, THEREFORE, in consideration of the premises and in order to induce
the Lenders to make Advances under the Credit Agreement, the Grantor hereby
agrees with the Agent for its benefit and the ratable benefit of the Lenders as
follows:

         SECTION . COLLATERAL ASSIGNMENT. The Grantor hereby assigns to the
Agent for its benefit and the ratable benefit of the Lenders, and hereby grants
to the Agent for its benefit and the ratable benefit of the Lenders a security
interest in, all of the Grantor's right, title and interest in and to the
following (the "COLLATERAL"): the Support Agreement as it may be amended or
otherwise modified from time to time (the "ASSIGNED AGREEMENT"), including,
without limitation, (i) all rights of the Grantor to receive moneys due and to
become due under or pursuant to the Assigned Agreement, (ii) all rights of the
Grantor to receive proceeds of any insurance, indemnity, warranty or guaranty
with respect to the Assigned Agreement, (iii) claims of the Grantor for damages
arising out of or for breach of or default under the Assigned Agreement, (iv)
the right of the Grantor to terminate the Assigned Agreement, to perform
thereunder and to compel performance and otherwise exercise all remedies
thereunder, and (iv) all proceeds of any and all of the foregoing Collateral.

         SECTION . SECURITY FOR OBLIGATIONS. This Agreement secures the payment
of all obligations of the Borrower now or hereafter existing under the Credit
Agreement and the Notes, whether for principal, interest, fees, expenses or
otherwise, and all obligations of the Grantor now or hereafter existing under
this Agreement (all such obligations of the Borrower and the Grantor being the
"OBLIGATIONS"). Without limiting the generality of the foregoing, this Agreement
secures the payment of all amounts which constitute part of the Obligations and
would be owed by the Borrower to the Agent or the Lenders under the Credit
Agreement and the Notes but for the fact that
<PAGE>   124

they are unenforceable or not allowable due to the existence of a bankruptcy,
reorganization or similar proceeding involving the Borrower.

         SECTION . GRANTOR REMAINS LIABLE. Anything herein to the contrary
notwithstanding, (a) the Grantor shall remain liable under the contracts and
agreements included in the Collateral to the extent set forth therein to perform
all of its duties and obligations thereunder to the same extent as if this
Agreement had not been executed, (b) the exercise by the Agent of any of the
rights hereunder shall not release the Grantor from any of its duties or
obligations under the contracts and agreements included in the Collateral, and
(c) neither the Agent nor any Bank shall have any obligation or liability under
the contracts and agreements included in the Collateral by reason of this
Agreement, nor shall the Agent or any Bank be obligated to perform any of the
obligations or duties of the Grantor thereunder or to take any action to collect
or enforce any claim for payment assigned hereunder.

         SECTION . REPRESENTATIONS AND WARRANTIES. The Grantor represents and
warrants as follows:

                  () The Assigned Agreement, a true and complete copy of which
         has been furnished to each Bank, has been duly authorized, executed and
         delivered by all parties thereto, has not been amended or otherwise
         modified except as permitted by Section 7, is in full force and effect
         and is binding upon and enforceable against all parties thereto in
         accordance with its terms. There exists no default under the Assigned
         Agreement by any party thereto.

                  () The chief place of business and chief executive office of
         the Grantor and the office where the Grantor keeps its records
         concerning the Collateral are located at its address specified in
         Section 15. None of the Collateral is evidenced by a promissory note or
         other instrument (it being understood that the Assigned Agreement does
         not constitute a promissory note or other instrument).

                  () The Grantor is the legal and beneficial owner of the
         Collateral free and clear of any lien, security interest, option or
         other charge or encumbrance except for the security interest created by
         this Agreement. No effective financing statement or other document
         similar in effect covering all or any part of the Collateral is on file
         in any recording office, except such as may have been filed in favor of
         the Agent relating to this Agreement. The Grantor has no trade names.

                  () This Agreement creates a valid and perfected first priority
         security interest in the Collateral, securing the payment of the
         Obligations, and all filings and other actions necessary or desirable
         to perfect and protect such security interest have been duly taken.

                  () No consent of any other person or entity and no
         authorization, approval or other action by, and no notice to or filing
         with, any governmental authority or regulatory body is required () for
         the grant by the Grantor of the assignment and security interest
         granted hereby or for the execution, delivery or performance of this
         Agreement by the Grantor, () for the

<PAGE>   125


         perfection or maintenance of the assignment and security interest
         created hereby (including the first priority nature of such assignment
         and security interest) or () for the exercise by the Agent of its
         rights and remedies hereunder.

                  () There are no conditions precedent to the effectiveness of
         this Agreement that have not been satisfied or waived.

                  () The Grantor has, independently and without reliance upon
         the Agent or any Bank and based on such documents and information as it
         has deemed appropriate, made its own credit analysis and decision to
         enter into this Agreement.

         SECTION . FURTHER ASSURANCES. () The Grantor agrees that from time to
time, at the expense of the Grantor, the Grantor will promptly execute and
deliver all further instruments and documents, and take all further action, that
may be necessary or desirable, or that the Agent may reasonably request, in
order to perfect and protect the assignment and security interest granted or
purported to be granted hereby or to enable the Agent to exercise and enforce
its rights and remedies hereunder with respect to any Collateral. Without
limiting the generality of the foregoing, the Grantor will execute and file such
financing or continuation statements, or amendments thereto, and such other
instruments or notices, as may be necessary or desirable, or as the Agent may
reasonably request, in order to perfect and preserve the assignment and security
interest granted or purported to be granted hereby.

         () The Grantor hereby authorizes the Agent to file one or more
financing or continuation statements, and amendments thereto, relating to all or
any part of the Collateral without the signature of the Grantor where permitted
by law. A photocopy or other reproduction of this Agreement or any financing
statement covering the Collateral or any part thereof shall be sufficient as a
financing statement where permitted by law.

         SECTION . PLACE OF PERFECTION; RECORDS. The Grantor shall keep its
chief place of business and chief executive office and the office where it keeps
its records concerning the Collateral at the location therefor specified in
Section 4(b) or, upon 30 days' prior written notice to the Agent, at any other
locations in a jurisdiction where all action required by Section 5 shall have
been taken with respect to the Collateral. The Grantor will hold and preserve
such records and will permit representatives of the Agent at any time during
normal business hours to inspect and make abstracts from such records.

         SECTION . AS TO THE ASSIGNED AGREEMENT. () The Grantor shall at its
expense:

                  () perform and observe all the terms and provisions of the
         Assigned Agreement to be performed or observed by it, maintain the
         Assigned Agreement in full force and effect, enforce the Assigned
         Agreement in accordance with its terms, and take all such action to
         such end as may be from time to time reasonably requested by the Agent.



<PAGE>   126

                  () furnish to the Agent promptly upon receipt thereof copies
         of all notices, requests and other documents received by the Grantor
         under or pursuant to the Assigned Agreement, and from time to time (A)
         furnish to the Agent such information and reports regarding the
         Collateral as the Agent may reasonably request and (B) upon request of
         the Agent make to any other party to the Assigned Agreement such
         demands and requests for information and reports or for action as the
         Grantor is entitled to make thereunder.

         ()       The Grantor shall not:

                  () sell, assign (by operation of law or otherwise) or
         otherwise dispose of, or grant any option with respect to, any of the
         Collateral, or create or permit to exist any lien, security interest,
         option or other charge or encumbrance upon or with respect to any of
         the Collateral, except for the assignment and security interest under
         this Agreement;

                  () cancel or terminate the Assigned Agreement or consent to or
         accept any cancellation or termination thereof;

                  () amend or otherwise modify the Assigned Agreement or give
         any consent, waiver or approval thereunder; or

                  () waive any default under or breach of the Assigned
         Agreement; or

                  () take any other action in connection with the Assigned
         Agreement which would impair the value of the interest or rights of the
         Grantor thereunder or which would impair the interest or rights of the
         Agent.

         SECTION . PAYMENTS UNDER THE ASSIGNED AGREEMENT. () The Grantor agrees,
and has effectively so instructed the Parent that upon the occurrence and during
the continuance of an Event of Default, all payments due or to become due under
or in connection with the Assigned Agreement shall be made directly to the Agent
at its address set forth in Section 15.

         () Except as set forth in Section 12, all moneys received or collected
pursuant to subsection (a) above shall be applied to all or any part of the
Obligations as the Agent may elect.

         SECTION . AGENT APPOINTED ATTORNEY-IN-FACT. The Grantor hereby appoints
the Agent the Grantor's attorney-in-fact, with full authority in the place and
stead of the Grantor and in the name of the Grantor or otherwise, from time to
time in the Agent's discretion to take any action and to execute any instrument
which the Agent may deem necessary or advisable to accomplish the purposes of
this Agreement, including, without limitation:

                  () to ask, demand, collect, sue for, recover, compromise,
         receive and give acquittance and receipts for moneys due and to become
         due under or in connection with the Collateral,

                  () to receive, indorse and collect any drafts or other
         instruments or documents in connection therewith, and



<PAGE>   127


                  () to file any claims or take any action or institute any
         proceedings which the Agent may deem necessary or desirable for the
         collection of any of the Collateral or otherwise to enforce compliance
         with the terms and conditions of the Assigned Agreement or the rights
         of the Agent with respect to any of the Collateral.

         SECTION . AGENT MAY PERFORM. If the Grantor fails to perform any
agreement contained herein, the Agent may itself perform, or cause performance
of, such agreement, and the expenses of the Agent incurred in connection
therewith shall be payable by the Grantor under Section 13(b).

         SECTION . THE AGENT'S DUTIES. The powers conferred on the Agent
hereunder are solely to protect its interest in the Collateral and shall not
impose any duty upon it to exercise any such powers. Except for the safe custody
of any Collateral in its possession and the accounting for moneys actually
received by it hereunder, the Agent shall have no duty as to any Collateral or
as to the taking of any necessary steps to preserve rights against any parties
or any other rights pertaining to any Collateral. The Agent shall be deemed to
have exercised reasonable care in the custody and preservation of any Collateral
in its possession if such Collateral is accorded treatment substantially equal
to that which Citibank accords its own property.

         SECTION . REMEDIES. If any Event of Default shall have occurred and be
continuing:

                  () The Agent may exercise any and all rights and remedies of
         the Grantor under or in connection with the Assigned Agreement or
         otherwise in respect of the Collateral, including, without limitation,
         any and all rights of the Grantor to demand or otherwise require
         payment of any amount under, or performance of any provision of, the
         Assigned Agreement.

                  () All payments received by the Grantor under or in connection
         with the Assigned Agreement or otherwise in respect of the Collateral
         shall be received in trust for the benefit of the Agent, shall be
         segregated from other funds of the Grantor and shall be forthwith paid
         over to the Agent in the same form as so received (with any necessary
         indorsement).

                  () All payments made under or in connection with the Assigned
         Agreement or otherwise in respect of the Collateral, and all cash
         proceeds in respect of any sale of, collection from, or other
         realization upon all or any part of the Collateral, received by the
         Agent may, in the discretion of the Agent, be held by the Agent as
         collateral for, and/or then or at any time thereafter applied (after
         payment of any amounts payable to the Agent pursuant to Section 13) in
         whole or in part by the Agent for the ratable benefit of the Lenders
         against, all or any part of the Obligations in such order as the Agent
         shall elect. Any surplus of such payments or cash proceeds held by the
         Agent and remaining after payment in full of all the Obligations shall
         be paid over to the Grantor or to whomsoever may be lawfully entitled
         to receive such surplus.

                  () The Agent may exercise in respect of the Collateral, in
         addition to other rights and remedies provided for herein or otherwise
         available to it, all the rights and remedies of a secured party on
         default under the Uniform Commercial Code in effect in the State of New
         York at that time (the "CODE") (whether or not the Code applies to the
         affected Collateral).


<PAGE>   128

         SECTION . INDEMNITY AND EXPENSES. () The Grantor agrees to indemnify
the Agent from and against any and all claims, losses and liabilities (including
reasonable attorneys' fees) growing out of or resulting from this Agreement
(including, without limitation, enforcement of this Agreement), except claims,
losses or liabilities resulting from the Agent's gross negligence or willful
misconduct.

         () The Grantor will upon demand pay to the Agent the amount of any and
all reasonable expenses, including the reasonable fees and expenses of its
counsel and of any experts and agents, which the Agent may incur in connection
with () the administration of this Agreement, () the custody or preservation of,
or the sale of, collection from or other realization upon, any of the
Collateral, () the exercise or enforcement of any of the rights of the Agent or
the Lenders hereunder or () the failure by the Grantor to perform or observe any
of the provisions hereof.

         SECTION . AMENDMENTS; ETC. No amendment or waiver of any provision of
this Agreement, and no consent to any departure by the Grantor herefrom shall in
any event be effective unless the same shall be in writing and signed by the
Agent, and then such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given.

         SECTION . ADDRESSES FOR NOTICES. All notices and other communications
provided for hereunder shall be in writing (including telecopier, telegraphic,
telex or cable communication) and mailed, telecopied, telegraphed, telexed,
cabled or delivered to it, if to the Grantor, at its address at 2000 Second
Avenue, Detroit, MI 48226, Attention: Christopher Arvani, and if to the Agent,
at its address specified in the Credit Agreement, or, as to either party, at
such other address as shall be designated by such party in a written notice to
the other party. All such notices and other communications shall, when mailed,
telecopied, telegraphed, telexed or cabled, be effective when deposited in the
mails, telecopied, delivered to the telegraph company, confirmed by telex
answerback or delivered to the cable company, respectively.

         SECTION . CONTINUING ASSIGNMENT AND SECURITY INTEREST; ASSIGNMENTS
UNDER CREDIT AGREEMENT. This Agreement shall create a continuing assignment of
and security interest in the Collateral and shall () remain in full force and
effect until the later of (x) the payment in full of the Obligations and all
other amounts payable under this Agreement and (y) the expiration or termination
of the Commitments, () be binding upon the Grantor, its successors and assigns,
and () inure, together with the rights and remedies of the Agent hereunder, to
the benefit of the Agent, the Lenders and their respective successors,
transferees and assigns. Without limiting the generality of the foregoing clause
(iii), any Bank may assign or otherwise transfer all or any portion of its
rights and obligations under the Credit Agreement (including, without
limitation, all or any portion of its Commitment, the Advances owing to it and
any Note held by it) held by it to any other person or entity, and such other
person or entity shall thereupon become vested with all the benefits in respect
thereof granted to such Bank herein or otherwise, subject, however, to the
provisions of Article VI (concerning the Agent) of the Credit Agreement. Upon
the later of the payment in full of the Obligations and all other amounts
payable under this Agreement and the expiration or termination of the
Commitments, the security interest granted hereby shall terminate and all rights
to the Collateral shall revert to the Grantor. Upon any such termination, the
Agent 


<PAGE>   129

will, at the Grantor's expense, execute and deliver to the Grantor such 
documents as the Grantor shall reasonably request to evidence such termination.

         SECTION . GOVERNING LAW; TERMS. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York, except to the
extent that the validity or perfection of the assignment and security interest
hereunder, or remedies hereunder, in respect of any particular Collateral are
governed by the laws of a jurisdiction other than the State of New York. Unless
otherwise defined herein or in the Credit Agreement, terms used in Article 9 of
the Code are used herein as therein defined.

         IN WITNESS WHEREOF, the Grantor has caused this Agreement to be duly
executed and delivered by its officer thereunto duly authorized as of the date
first above written.
