                           THE LOANS AND THE SERVICES

      Section 2.01. Loan at the Closing of the Initial Public Offering.
Immediately following the closing (the "Closing") of the Initial Public
Offering, the Company shall lend to SPX all of the net proceeds of the Initial
Public Offering in excess of $15 million, less the amount of the Company's cash

      Section 2.02. Daily Cash Management. For so long as SPX performs cash
management services for each of its Subsidiaries, including sweeps of all of the
cash of SPX's Subsidiaries, SPX shall provide cash management services to the
Company consistent with the services provided to its Subsidiaries, including
sweeping to SPX all of the Company's Excess Cash at such times as SPX sweeps
cash of SPX's Subsidiaries; provided, however, that no sweeping or loan
hereunder will be made if such loan would result in a violation of law or
subject the Company to any additional regulation. The Company agrees to permit
SPX to sweep its Excess Cash on a daily basis or as otherwise performed for its
Subsidiaries and that the amount of Excess Cash so swept shall be considered a
loan from the Company to SPX.

      Section 2.03. Interest Rate. SPX shall be required to pay interest on all
amounts loaned and deemed loaned by the Company to SPX pursuant to this
Agreement from the date such amounts are loaned or deemed to have been loaned to

the average amount outstanding at

                                       2

all times during such day), quarterly in arrears on each March 31, June 30,
September 30 and December 31, at a per annum rate equal to the weighted average
daily interest that SPX paid for Revolving Loans (as defined in the SPX Credit
Agreement) in the fiscal quarter prior to the fiscal quarter for which interest
is being paid; provided, however that interest paid for loans made prior to
October 1, 2000 shall bear interest at a per annum rate of 8.5% until October 1,
2000, when such loans shall begin bearing interest at the weighted average daily
interest rate that SPX paid for Revolving Loans in the fiscal quarter ended
September 30, 2000. Interest payable pursuant to this Section shall, at SPX's
option, be payable by increasing the amount due under this Agreement, rather
than by payment in cash.

      Five business days after the beginning of each fiscal quarter, SPX shall
deliver to the Company a certificate stating the weighted average daily interest
rate that SPX paid for Revolving Loans in the prior fiscal quarter and providing
any information relating to the calculation of such interest rate that is
reasonably requested by the Company.

      Section 2.04. Demand by the Company. Within two business days of the
Company's written request, SPX shall repay any and all outstanding amounts
loaned or deemed loaned under this Agreement, together with unpaid interest
thereon to the date of such request.

      Section 2.05. Prepayment by SPX. Any or all amounts due under this
Agreement, together with unpaid interest thereon to the date of repayment may be
prepaid by SPX at any time without premium or penalty.

      Section 2.06. Computation of Outstanding Loans. Within two business days
of (x) the end of each of SPX's fiscal quarters and (y) the Company's request,
SPX shall provide the Company with a calculation setting forth the total amount
that SPX owed the Company under this Agreement on the date of such request.

      Section 2.07 Services. The cash management services to be provided by SPX
to the Company pursuant to this Agreement shall include, but not be limited to,
processing lock box receipts, funding and processing payments cleared through
accounts payable, payroll, wire transfers and other payments requested by the
Company. The services provided under this Section 2.07 shall be deemed to be
"Services" provided pursuant to the Management Services Agreement between SPX
and the Company, and shall be subject to all of the terms of such agreement;
provided, however, that, such Services shall terminate upon the earlier to occur
of (x) a termination of such Services in accordance with the terms of the
Management Services Agreement and (y) the termination of this Agreement pursuant
to Section 3.01 hereof.

                                   ARTICLE III
                              TERM AND TERMINATION

      Section 3.01. Term. This Agreement shall commence on the closing of the
Initial Public Offering and shall automatically terminate on the earlier to
occur of (x) the date that SPX owns shares of common stock of the Company
representing less than 50% of the aggregate amount of the outstanding shares of
Class A Common Stock and Class B Common Stock and (y) the occurrence of an Event
of Default (as defined in the SPX Credit Agreement) under the SPX Credit
Agreement.

      Section 3.02 Effect of Termination. Upon the termination of this
Agreement, (x) SPX shall not have the right to sweep, and the Company shall not
have any obligation to loan to SPX, any additional amounts under this Agreement
and (y) all amounts due under this Agreement shall become immediately due and
payable and shall thereafter bear interest at the rate in effect at the time
plus 2%, per year; provided, however, that nothing contained in this Agreement
shall be deemed to establish or require the payment of a rate of interest in
excess of the amount legally enforceable. In the event that the rate of interest
so required to be paid exceeds the maximum rate legally enforceable, whether as
a result of acceleration of maturity or otherwise, the rate of interest so
required to be paid shall be automatically reduced to the maximum rate legally
enforceable, and any excess paid over such maximum enforceable rate shall be
automatically credited on account of the principal hereof.

                                   ARTICLE IV
                                     PAYMENT

      Section 4.01. Payment. All payments of amounts owed under this Agreement
shall be made in lawful money of the United States of America in same day funds
to the account of the Company at such place as shall be designated in writing by
the Company for such purpose.

      Section 4.02. Payment on a non-Business Day. Whenever any payment under
this Agreement shall be stated to be due on a day which is not a business day in
Delaware, Michigan or New York, such payment shall be made on the next
succeeding business day and such extension of time shall be included in the
computation of the payment of interest on amounts due under this Agreement.
