        This Amendment No. 3 (this "Final Amendment") amends and supplements the
Tender Offer Statement on Schedule 14D-1 filed with the Securities and Exchange
Commission on June 30, 1999, as amended by Amendments Nos. 1 and 2 thereto filed
on July 6, and July 20, 1999, respectively (the "Schedule 14D-1"), relating to
the offer by COMP Acquisition Co., a California corporation ("Purchaser") and
wholly owned subsidiary of Compuware Corporation, a Michigan corporation
("Compuware"), to purchase all outstanding shares of Common Stock, no par value
(the "Shares"), of Data Processing Resources Corporation, a California
corporation (the "Company"), at $24.00 per Share, net to the seller in cash,
upon the terms and subject to the conditions set forth in the Offer to Purchase,
dated June 30, 1999 (the "Offer to Purchase"), and in the related Letter of
Transmittal (which, together with any amendments and supplements thereto,
collectively constitute the "Offer"). Capitalized terms used and not defined
herein shall have the meanings assigned to such terms in the Offer and the
Schedule 14D-1.

        In accordance with General Instruction F to Schedule 14D-1, this Final
Amendment also constitutes a statement on Schedule 13D with respect to the
acquisition by Purchaser of the Shares as more fully described below.

        Item 4 of the Schedule 14D-1 is hereby amended as follows:

ITEM 4. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

        (a)-(c) The total amount of funds required by Purchaser to consummate
the Offer and the Merger is estimated to be approximately $354.6 million
(assuming the Purchase of all Shares outstanding), plus approximately $2.5
million to pay related fees and expenses. In addition, as indicated in Section
10 of the Offer to Purchase under the heading "Convertible Notes," the Company
will be required to offer to repurchase its 5 1/4% Convertible Subordinated
Notes due 2005 (the "Notes") following the earlier of the consummation of the
Offer or Merger, for the aggregate principal amount of $115 million plus accrued
interest. Purchaser plans to obtain all the funds needed for the Offer and the
Merger, and to repurchase the Notes, from Compuware. Compuware will obtain such
funds in part from the credit facility referred to below. As of March 31, 1999,
Compuware had approximately $193 million in cash and cash equivalents and
approximately $310 million in short term investments. Neither Purchaser nor
Compuware has conditioned the Offer or the Merger on obtaining financing.

        On June 30, 1999, Compuware countersigned a commitment letter, dated
June 29, 1999, from Morgan Stanley Senior Funding, Inc. ("Morgan Stanley") and
Comerica Bank ("Comerica"), pursuant to which Morgan Stanley and Comerica
committed to provide a credit facility to Compuware on certain terms and
conditions. As contemplated by the commitment letter, Compuware, Morgan Stanley,
Comerica and various other lenders entered into a credit agreement, dated as of
August 3, 1999. While the credit agreement provides that Morgan Stanley and
Comerica are obligated to provide to Compuware, on specified terms and subject
to specified conditions, up to $900 million in credit financing (Morgan Stanley
is obligated to provide $540 million of the total commitment, and Comerica is
obligated to provide $360 million), it is expected that they will act as agents
for a syndicate of financial institutions which, together with Morgan Stanley
and Comercia, will provide the credit facility.

        Approximately $300 million from the credit facility was advanced to
Compuware on August 4, 1999 to finance a portion of the purchase price of the
Shares pursuant to the Offer and to pay certain fees and expenses relating to
the credit facility. The balance of the purchase price was funded with
Compuware's own funds. The remaining funds needed by Compuware to purchase
Shares pursuant to the Merger, to repurchase Notes, to finance the payments to
be made upon the exercise of options to purchase Shares and to pay related fees
and expenses is expected to come from Compuware's internal sources and/or from
further borrowings under the credit facility. The balance of the credit
facility is expected to be used for other corporate purposes.
<PAGE>   5
        The credit facility is a four year senior bank revolving credit
facility, with scheduled reductions of the commitments under the facility of
$100 million, $100 million and $700 million at the end of the second, third and
fourth years, respectively. Outstanding loans under the credit facility are to
be repaid if at any time their aggregate principal amount exceeds the then total
credit facility commitment. The interest rates on outstanding loans under the
credit facility will, at Compuware's option, be either (i) the Eurodollar
rate, plus a margin of 1.25% initially, or (ii) the higher of the Comerica prime
rate or 0.5% over the federal funds rate, plus a margin of 0.25% initially. In
addition, the credit agreement provides for commitment fees on the unutilized
commitments under the credit facility of 0.25% per annum initially. The interest
rate margins and commitment fees will be adjusted after six months according to
Compuware's then credit rating.

        The credit agreement contains representations, warranties,
covenants, events of default and conditions customary for credit facilities of
this size and type. Compuware has agreed to pay certain fees to Morgan
Stanley and Comerica with respect to the commitment letter and to Morgan
Stanley, Comerica and the other lenders with respect to the credit facility.
Compuware also has agreed to reimburse certain expenses of Morgan Stanley and
Comerica in connection with the commitment letter and to provide customary
indemnities to Morgan Stanley, Comerica and the other lenders in connection with
the credit facility.

        The foregoing summary of the sources and amount of funds is qualified in
its entirety by reference to the text of the credit agreement, including the
exhibits and schedules thereto, and the commitment letter. A copy of the credit
agreement is attached as Exhibit (b)(2) to this Final Amendment. A copy of the
commitment letter is attached as Exhibit (b)(1) to Amendment No. 1 to the
Schedule 14D-1.

    Although no definitive plan or arrangement for repayment of borrowings under
the credit facility has been made, Compuware anticipates such borrowings will be
repaid with internally generated funds (including funds of the Company) and from
other sources which may include the proceeds of future bank financings or the
public or private sale of debt or equity securities. No decision has been made
concerning the method Compuware will use to repay the borrowings under the
credit facility. Such decision will be made based on Compuware's review from
time to time of the advisability of particular actions, as well as prevailing
interest rates, financial and other economic conditions and such other factors
as Compuware may deem appropriate.

        Item 6 of the Schedule 14D-1 is hereby amended to read in its entirety
as follows:

ITEM 6. INTEREST IN SECURITIES OF THE SUBJECT COMPANY.

        (a) and (b) The information set forth in the Introduction and Section
8 ("Certain Information Concerning Purchaser and Compuware") of the Offer to
Purchase is incorporated herein by reference.

        The Offer expired at 12:00 midnight, Eastern Time, Wednesday, July 28,
1999. Purchaser was advised by EquiServe, the Depositary for the Offer, that
based on a preliminary count 13,880,180 Shares, or in excess of 93% of the
outstanding Shares of the Company (excluding Shares tendered subject to
guarantees of delivery or receipt of additional documentation), were tendered in
response to the Offer (exceeding the 91% minimum tender condition). The results
of the Offer were publicly announced in a press release on Thursday, July 29,
1999, a copy of which is attached as Exhibit (a)(9) to this Final Amendment.

        On Wednesday, August 4, 1999, Purchaser accepted for payment and
purchased a total of 14,401,187 Shares, constituting all Shares validly tendered
and not properly withdrawn pursuant to the Offer. The Shares purchased represent
approximately 97.5% of the 14,775,361 shares of the Company outstanding on such
date.


        Item 10 of the Schedule 14D-1 is hereby amended by inserting the
following at the conclusion thereof:

ITEM 10. ADDITIONAL INFORMATION.

        The waiting period under the pre-merger notification requirement of the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, with respect
to the Offer and follow-on Merger expired on July 15, 1999.

            CREDIT AGREEMENT, dated as of August 3, 1999, among COMPUWARE
CORPORATION, a Michigan corporation (the "Borrower"), the Lenders party hereto
from time to time, COMERICA BANK, as administrative agent and co-arranger (in
such capacity, the "Administrative Agent"), and MORGAN STANLEY SENIOR FUNDING,
INC., as lead arranger, syndication agent and book manager (in such capacity,
the "Lead Arranger"). All capitalized terms used herein and defined in Section
11 are used herein as therein defined.


                              W I T N E S S E T H :


            WHEREAS, subject to and upon the terms and conditions set forth
herein, the Lenders are willing to make available to the Borrower the respective
credit facilities provided for herein;

            NOW, THEREFORE, IT IS AGREED:

            SECTION 1. Amount and Terms of Credit.

            1.01 The Commitments. (a) Subject to and upon the terms and
conditions set forth herein, each Lender severally agrees to make, at any time
and from time to time on or after the Effective Date and prior to the Final
Maturity Date, a revolving loan or revolving loans (each a "Revolving Loan" and,
collectively, the "Revolving Loans") to the Borrower, which Revolving Loans (i)
shall, at the option of the Borrower, be incurred and maintained as, and/or
converted into, Base Rate Loans or Eurodollar Loans, provided that, except as
otherwise specifically provided in Section 1.10(b), all Revolving Loans
comprising the same Borrowing shall at all times be of the same Type, (ii) may
be repaid and reborrowed in accordance with the provisions hereof, (iii) shall
not exceed for any Lender at any time outstanding that aggregate principal
amount which, when added to the product of (x) such Lender's Percentage and (y)
the sum of (I) the aggregate amount of all Letter of Credit Outstandings
(exclusive of Unpaid Drawings which are repaid with the proceeds of, and
simultaneously with the incurrence of, the respective incurrence of Revolving
Loans) at such time and (II) the aggregate principal amount of all Swingline
Loans (exclusive of Swingline Loans which are repaid with the proceeds of, and
simultaneously with the incurrence of, the respective incurrence of Revolving
Loans) then outstanding, equals the Available Commitment of such Lender at such
time, and (iv) shall not exceed for all Lenders at any time outstanding that
aggregate principal amount which, when added to the sum of (I) the aggregate
amount of all Letter of Credit Outstandings (exclusive of Unpaid Drawings which
are repaid with the proceeds of, and simultaneously with the incurrence of, the
respective incurrence of Revolving Loans) at such time and (II) the aggregate
principal amount of all Swingline Loans (exclusive of Swingline Loans which are
repaid with the proceeds of, and simultaneously with the incurrence of, the
respective incurrence of Revolving Loans) then outstanding, equals the Total
Available Commitment at such time.

            (b) Subject to and upon the terms and conditions set forth herein,
the Swingline Lender agrees to make, at any time and from time to time on or
after the Effective Date and prior to the Swingline Expiry Date, a revolving
loan or revolving loans (each a "Swingline Loan" and, collectively, the
"Swingline Loans") to the Borrower, which Swingline




<PAGE>   7

Loans (i) shall be made and maintained as Base Rate Loans, (ii) may be repaid
and reborrowed in accordance with the provisions hereof, (iii) shall not exceed
in aggregate principal amount at any time outstanding, when combined with the
aggregate principal amount of all Revolving Loans then outstanding and the
aggregate amount of all Letter of Credit Outstandings at such time, an amount
equal to the Total Available Commitment at such time, and (iv) shall not exceed
in aggregate principal amount at any time outstanding the Maximum Swingline
Amount. Notwithstanding anything to the contrary contained in this Section
1.01(b), (i) the Swingline Lender shall not be obligated to make any Swingline
Loans at a time when a Lender Default exists unless the Swingline Lender has
entered into arrangements satisfactory to it and the Borrower to eliminate the
Swingline Lender's risk with respect to the Defaulting Lender's or Lenders'
participation in such Swingline Loans, including by cash collateralizing such
Defaulting Lender's or Lenders' Percentage of the outstanding Swingline Loans
and (ii) the Swingline Lender shall not make any Swingline Loan after it has
received written notice from the Borrower or the Required Lenders stating that a
Default or an Event of Default exists and is continuing until such time as the
Swingline Lender shall have received written notice (A) of rescission of all
such notices from the party or parties originally delivering such notice or
notices or (B) of the waiver of such Default or Event of Default by the Required
Lenders.

            (c) On any Business Day, the Swingline Lender may, in its sole
discretion, give notice to the Lenders that the Swingline Lender's outstanding
Swingline Loans shall be funded with one or more Borrowings of Revolving Loans
(provided that such notice shall be deemed to have been automatically given upon
the occurrence of a Default or an Event of Default under Section 10.05 or upon
the exercise of any of the remedies provided in the last paragraph of Section
10), in which case one or more Borrowings of Revolving Loans constituting Base
Rate Loans (each such Borrowing, a "Mandatory Borrowing") shall be made on the
immediately succeeding Business Day by all Lenders pro rata based on each
Lender's Percentage (determined before giving effect to any termination of the
Commitments pursuant to the last paragraph of Section 10) and the proceeds
thereof shall be applied directly by the Swingline Lender to repay the Swingline
Lender for such outstanding Swingline Loans. Each Lender hereby irrevocably
agrees to make Revolving Loans upon one Business Day's notice pursuant to each
Mandatory Borrowing in the amount and in the manner specified in the preceding
sentence and on the date specified in writing by the Swingline Lender
notwithstanding (i) the amount of the Mandatory Borrowing may not comply with
the Minimum Borrowing Amount otherwise required hereunder, (ii) whether any
conditions specified in Section 6 are then satisfied, (iii) whether a Default or
an Event of Default then exists, (iv) the date of such Mandatory Borrowing and
(v) the amount of the Total Available Commitment at such time. In the event that
any Mandatory Borrowing cannot for any reason be made on the date otherwise
required above (including, without limitation, as a result of the commencement
of a proceeding under the Bankruptcy Code with respect to the Borrower), then
each Lender hereby agrees that it shall forthwith purchase (as of the date the
Mandatory Borrowing would otherwise have occurred, but adjusted for any payments
received from the Borrower on or after such date and prior to such purchase)
from the Swingline Lender such participations in the outstanding Swingline Loans
as shall be necessary to cause the Lenders to share in such Swingline Loans
ratably based upon their respective Percentages (determined before giving effect
to any termination of the Commitments pursuant to the last paragraph of Section
10), provided that



                                      -2-
<PAGE>   8

(x) all interest payable on the Swingline Loans shall be for the account of the
Swingline Lender until the date as of which the respective participation is
required to be purchased and, to the extent attributable to the purchased
participation, shall be payable to the participant from and after such date and
(y) at the time any purchase of participations pursuant to this sentence is
actually made, the purchasing Lender shall be required to pay the Swingline
Lender interest on the principal amount of participation purchased for each day
from and including the day upon which the Mandatory Borrowing would otherwise
have occurred to but excluding the date of payment for such participation, at
the overnight Federal Funds Rate for the first three days and at the rate
otherwise applicable to Revolving Loans maintained as Base Rate Loans hereunder
for each day thereafter.

            1.02 Minimum Amount of Each Borrowing. The aggregate principal
amount of each Borrowing of Revolving Loans and Swingline Loans shall not be
less than the Minimum Borrowing Amount applicable thereto. More than one
Borrowing may occur on the same date (including more than one Borrowing of Base
Rate Loans and Eurodollar Loans), but at no time shall there be outstanding more
than fifteen Borrowings of Eurodollar Loans in the aggregate.

            1.03 Notice of Borrowing. (a) Whenever the Borrower desires to incur
(x) Eurodollar Loans hereunder, the Borrower shall give the Administrative Agent
at the Notice Office at least three Business Days' prior notice of each
Eurodollar Loan to be incurred hereunder and (y) Base Rate Loans hereunder
(excluding Swingline Loans and Revolving Loans made pursuant to a Mandatory
Borrowing), the Borrower shall give the Administrative Agent at the Notice
Office at least one Business Day's prior notice of each Base Rate Loan to be
incurred hereunder, provided that (in each case) any such notice shall be deemed
to have been given on a certain day only if given before 12:00 Noon (Detroit,
Michigan time) on such day. Each such notice (each a "Notice of Borrowing"),
except as otherwise expressly provided in Section 1.10, shall be irrevocable and
shall be given by the Borrower in writing, or by telephone promptly confirmed in
writing, in the form of Exhibit A, appropriately completed to specify the
aggregate principal amount of the Revolving Loans to be incurred pursuant to
such Borrowing, the date of such Borrowing (which shall be a Business Day),
whether the Revolving Loans being incurred pursuant to such Borrowing are to be
initially maintained as Base Rate Loans or, to the extent permitted hereunder,
Eurodollar Loans and, if Eurodollar Loans, the initial Interest Period to be
applicable thereto. The Administrative Agent shall promptly give each Lender
notice of such proposed Borrowing, of such Lender's proportionate share thereof
and of the other matters required by the immediately preceding sentence to be
specified in the Notice of Borrowing.

            (b) (i) Whenever the Borrower desires to incur Swingline Loans
hereunder, the Borrower shall give the Swingline Lender no later than 3:00 P.M.
(Detroit, Michigan time) on the date that a Swingline Loan is to be incurred
hereunder, written notice or telephonic notice promptly confirmed in writing of
each Swingline Loan to be incurred hereunder. Each such notice shall be
irrevocable and specify in each case (A) the date of Borrowing (which shall be a
Business Day) and (B) the aggregate principal amount of the Swingline Loans to
be incurred pursuant to such Borrowing.



                                      -3-
<PAGE>   9

            (ii) Mandatory Borrowings shall be made upon the notice specified in
Section 1.01(c), with the Borrower irrevocably agreeing, by its incurrence of
any Swingline Loan, to the making of the Mandatory Borrowings as set forth in
Section 1.01(c).

            (c) Without in any way limiting the obligation of the Borrower to
confirm in writing any telephonic notice of any Borrowing or prepayment of
Loans, the Administrative Agent or the Swingline Lender, as the case may be, may
act without liability upon the basis of telephonic notice of such Borrowing or
prepayment, as the case may be, believed by the Administrative Agent or the
Swingline Lender, as the case may be, in good faith to be from the Chairman of
the Board, the Chief Executive Officer, the President, the Chief Financial
Officer, the Treasurer or any Assistant Treasurer of the Borrower, or from any
other authorized officer of the Borrower designated in writing by any of the
foregoing officers of the Borrower to the Administrative Agent as being
authorized to give such notices, prior to receipt of written confirmation. In
each such case, the Borrower hereby waives the right to dispute the
Administrative Agent's or Swingline Lender's record of the terms of such
telephonic notice of such Borrowing or prepayment of Loans, as the case may be,
absent manifest error.

            1.04 Disbursement of Funds. No later than 12:00 Noon (Detroit,
Michigan time) on the date specified in each Notice of Borrowing (or (x) in the
case of Swingline Loans, no later than 4:00 P.M. (Detroit, Michigan time) on the
date specified pursuant to Section 1.03(b)(i) or (y) in the case of Mandatory
Borrowings, no later than 12:00 Noon (Detroit, Michigan time) on the date
specified in Section 1.01(c)), each Lender will make available its pro rata
portion (determined in accordance with Section 1.07) of each such Borrowing
requested to be made on such date (or in the case of Swingline Loans, the
Swingline Lender will make available the full amount thereof). All such amounts
will be made available in Dollars and in immediately available funds at the
Payment Office, and, except for Revolving Loans made pursuant to a Mandatory
Borrowing, the Administrative Agent will make available to the Borrower at the
Payment Office the aggregate of the amounts so made available by the Lenders.
Unless the Administrative Agent shall have been notified by any Lender prior to
the date of Borrowing that such Lender does not intend to make available to the
Administrative Agent such Lender's portion of any Borrowing to be made on such
date, the Administrative Agent may assume that such Lender has made such amount
available to the Administrative Agent on such date of Borrowing and the
Administrative Agent may (but shall not be obligated to), in reliance upon such
assumption, make available to the Borrower a corresponding amount. If such
corresponding amount is not in fact made available to the Administrative Agent
by such Lender, the Administrative Agent shall be entitled to recover such
corresponding amount on demand from such Lender. If such Lender does not pay
such corresponding amount forthwith upon the Administrative Agent's demand
therefor, the Administrative Agent shall promptly notify the Borrower and the
Borrower shall immediately pay such corresponding amount to the Administrative
Agent. The Administrative Agent also shall be entitled to recover on demand from
such Lender or the Borrower, as the case may be, interest on such corresponding
amount in respect of each day from the date such corresponding amount was made
available by the Administrative Agent to the Borrower until the date such
corresponding amount is recovered by the Administrative Agent, at a rate per
annum equal to (i) if recovered from such Lender, at the overnight Federal Funds
Rate for the first three days and at the rate of interest otherwise



                                      -4-
<PAGE>   10

applicable to the respective Borrowing for each day thereafter and (ii) if
recovered from the Borrower, the rate of interest applicable to the respective
Borrowing, as determined pursuant to Section 1.08. Nothing in this Section 1.04
shall be deemed to relieve any Lender from its obligation to make Loans
hereunder or to prejudice any rights which the Borrower may have against any
Lender as a result of any failure by such Lender to make Loans hereunder.

            1.05 Notes. (a) The Borrower's obligation to pay the principal of,
and interest on, the Loans made by each Lender shall be evidenced in the
Register maintained by the Administrative Agent pursuant to Section 13.15 and
shall, if requested by such Lender, also be evidenced (i) if Revolving Loans, by
a promissory note duly executed and delivered by the Borrower substantially in
the form of Exhibit B-1, with blanks appropriately completed in conformity
herewith (each a "Revolving Note" and, collectively, the "Revolving Notes") and
(ii) if Swingline Loans, by a promissory note duly executed and delivered by the
Borrower substantially in the form Exhibit B-2, with blanks appropriately
completed in conformity herewith (the "Swingline Note").

            (b) The Revolving Note issued to each Lender shall (i) be executed
by the Borrower, (ii) be payable to such Lender or its registered assigns and be
dated the Effective Date (or, if issued after the Effective Date, be dated the
date of the issuance thereof), (iii) be in a stated principal amount equal to
the Commitment of such Lender (or, if issued after the termination thereof, be
in a stated principal amount equal to the outstanding Revolving Loans of such
Lender at such time) and be payable in the outstanding principal amount of the
Revolving Loans evidenced thereby, (iv) mature on the Final Maturity Date, (v)
bear interest as provided in the appropriate clause of Section 1.08 in respect
of the Base Rate Loans and Eurodollar Loans, as the case may be, evidenced
thereby, (vi) be subject to voluntary prepayment as provided in Section 4.01,
and mandatory repayment as provided in Section 4.02, and (vii) be entitled to
the benefits of this Agreement and the other Credit Documents.

            (c) The Swingline Note issued to the Swingline Lender shall (i) be
executed by the Borrower, (ii) be payable to the Swingline Lender or its
registered assigns and be dated the Effective Date, (iii) be in a stated
principal amount equal to the Maximum Swingline Amount and be payable in the
outstanding principal amount of the Swingline Loans evidenced thereby from time
to time, (iv) mature on the Swingline Expiry Date, (v) bear interest as provided
in the appropriate clause of Section 1.08 in respect of the Base Rate Loans
evidenced thereby, (vi) be subject to voluntary prepayment as provided in
Section 4.01, and mandatory repayment as provided in Section 4.02, and (vii) be
entitled to the benefits of this Agreement and the other Credit Documents.

            (d) Each Lender will note on its internal records the amount of each
Loan made by it and each payment in respect thereof and will prior to any
transfer of any of its Notes endorse on the reverse side thereof the outstanding
principal amount of Loans evidenced thereby. Failure to make any such notation
or any error in such notation shall not affect the Borrower's obligations in
respect of such Loans.



                                      -5-
<PAGE>   11

            1.06 Conversions. The Borrower shall have the option to convert, on
any Business Day, at least the Minimum Borrowing Amount of the outstanding
principal amount of Revolving Loans made to the Borrower pursuant to one or more
Borrowings of one or more Types of Revolving Loans into a Borrowing of another
Type of Revolving Loan, provided that, (i) except as otherwise provided in
Section 1.10(b), Eurodollar Loans may be converted into Base Rate Loans only on
the last day of an Interest Period applicable to the Revolving Loans being
converted and no such partial conversion of Eurodollar Loans shall reduce the
outstanding principal amount of such Eurodollar Loans made pursuant to a single
Borrowing to less than the Minimum Borrowing Amount applicable thereto, (ii)
unless the Required Lenders otherwise agree, Base Rate Loans may only be
converted into Eurodollar Loans if no Default or Event of Default is in
existence on the date of the conversion and (iii) no conversion pursuant to this
Section 1.06 shall result in a greater number of Borrowings of Eurodollar Loans
than is permitted under Section 1.02. Each such conversion shall be effected by
the Borrower by giving the Administrative Agent at the Notice Office prior to
12:00 Noon (Detroit, Michigan time) at least three Business Days' prior notice
(each a "Notice of Conversion") specifying the Revolving Loans to be so
converted, the Borrowing or Borrowings pursuant to which such Revolving Loans
were made and, if to be converted into Eurodollar Loans, the Interest Period to
be initially applicable thereto. The Administrative Agent shall give each Lender
prompt notice of any such proposed conversion affecting any of its Revolving
Loans. Swingline Loans may not be converted pursuant to this Section 1.06.

            1.07 Pro Rata Borrowings. All Borrowings of Revolving Loans under
this Agreement shall be incurred from the Lenders pro rata on the basis of their
Commitments. It is understood that no Lender shall be responsible for any
default by any other Lender of its obligation to make Revolving Loans hereunder
and that each Lender shall be obligated to make the Revolving Loans provided to
be made by it hereunder, regardless of the failure of any other Lender to make
its Revolving Loans hereunder.

            1.08 Interest. (a) The Borrower agrees to pay interest in respect of
the unpaid principal amount of each Base Rate Loan from the date of Borrowing
thereof until the earlier of (i) the maturity thereof (whether by acceleration
or otherwise) and (ii) the conversion of such Base Rate Loan to a Eurodollar
Loan at a rate per annum which shall be equal to the sum of the Applicable
Margin plus the Base Rate each as in effect from time to time.

            (b) The Borrower agrees to pay interest in respect of the unpaid
principal amount of each Eurodollar Loan from the date of Borrowing thereof
until the earlier of (i) the maturity thereof (whether by acceleration or
otherwise) and (ii) the conversion of such Eurodollar Loan to a Base Rate Loan
at a rate per annum which shall, during each Interest Period applicable thereto,
be equal to the sum of the Applicable Margin plus the Eurodollar Rate for such
Interest Period.

            (c) Overdue principal and, to the extent permitted by law, overdue
interest in respect of each Loan shall, in each case, bear interest at a rate
per annum equal to the greater of (x) the rate which is 2% in excess of the rate
then borne by such Loans and (y) the rate which is 2% in excess of the rate
otherwise applicable to Base Rate Loans from time to time, and all other



                                      -6-
<PAGE>   12

overdue amounts payable hereunder or under any other Credit Document shall bear
interest at a rate per annum equal to the rate which is 2% in excess of the rate
applicable to Base Rate Loans from time to time. Interest which accrues under
this Section 1.08(c) shall be payable on demand.

            (d) Accrued (and theretofore unpaid) interest shall be payable (i)
in respect of each Base Rate Loan, quarterly in arrears on each Quarterly
Payment Date, (ii) in respect of each Eurodollar Loan, on the last day of each
Interest Period applicable thereto and, in the case of an Interest Period in
excess of three months, on each date occurring at three month intervals after
the first day of such Interest Period, and (iii) in respect of each Loan, on any
repayment or prepayment (on the amount repaid or prepaid), at maturity (whether
by acceleration or otherwise) and, after such maturity, on demand, provided
that, in the case of Base Rate Loans, interest shall not be payable pursuant to
preceding clause (iii) at the time of any repayment or prepayment thereof (but
shall otherwise be payable as provided in preceding clause (i)) unless the
respective repayment or prepayment is made in conjunction with the repayment or
prepayment in full of all outstanding Revolving Loans or in conjunction with a
permanent reduction of the Total Commitment.

            (e) Upon each Interest Determination Date, the Administrative Agent
shall determine the Eurodollar Rate for each Interest Period applicable to the
respective Eurodollar Loans and shall promptly notify the Borrower and the
Lenders thereof either in writing or by telephone promptly confirmed in writing.
Each such determination shall, absent manifest error, be final and conclusive
and binding on all parties hereto.

            1.09 Interest Periods. At the time the Borrower gives any Notice of
Borrowing or Notice of Conversion in respect of the making of, or conversion
into, any Eurodollar Loan (in the case of the initial Interest Period applicable
thereto) or prior to 12:00 Noon (Detroit, Michigan time) on the third Business
Day prior to the expiration of an Interest Period applicable to such Eurodollar
Loan (in the case of any subsequent Interest Period), the Borrower shall have
the right to elect, by giving the Administrative Agent notice thereof, the
interest period (each an "Interest Period") applicable to such Eurodollar Loan,
which Interest Period shall, at the option of the Borrower, be a one, two, three
or six-month period, provided that:

            (i) all Eurodollar Loans comprising a Borrowing shall at all times
       have the same Interest Period;

            (ii) the initial Interest Period for any Eurodollar Loan shall
       commence on the date of Borrowing of such Eurodollar Loan (including the
       date of any conversion thereto from a Base Rate Loan) and each Interest
       Period occurring thereafter in respect of such Eurodollar Loan shall
       commence on the day on which the next preceding Interest Period
       applicable thereto expires;

            (iii) if any Interest Period for a Eurodollar Loan begins on a day
       for which there is no numerically corresponding day in the calendar month
       at the end of such Interest Period, such Interest Period shall end on the
       last Business Day of such calendar month;



                                      -7-
<PAGE>   13

            (iv) if any Interest Period for a Eurodollar Loan would otherwise
       expire on a day which is not a Business Day, such Interest Period shall
       expire on the next succeeding Business Day; provided, however, that if
       any Interest Period for a Eurodollar Loan would otherwise expire on a day
       which is not a Business Day but is a day of the month after which no
       further Business Day occurs in such month, such Interest Period shall
       expire on the next preceding Business Day;

            (v) unless the Required Lenders otherwise agree, no Interest Period
       may be selected at any time when a Default or an Event of Default is then
       in existence; and

            (vi) no Interest Period in respect of any Borrowing of Eurodollar
       Loans shall be selected which extends beyond the Final Maturity Date.

            If upon the expiration of any Interest Period applicable to a
Borrowing of Eurodollar Loans, the Borrower has failed to elect, or is not
permitted to elect, a new Interest Period to be applicable to such Eurodollar
Loans as provided above, the Borrower shall be deemed to have elected to convert
such Eurodollar Loans into Base Rate Loans effective as of the expiration date
of such current Interest Period.

            1.10 Increased Costs, Illegality, etc. (a) In the event that any
Lender shall have determined (which determination shall, absent manifest error,
be final and conclusive and binding upon all parties hereto but, with respect to
clause (i) below, may be made only by the Administrative Agent):

            (i) on any Interest Determination Date that, by reason of any
       changes arising after the date of this Agreement affecting the interbank
       Eurodollar market, adequate and fair means do not exist for ascertaining
       the applicable interest rate on the basis provided for in the definition
       of Eurodollar Rate; or

            (ii) at any time, that such Lender shall incur increased costs or
       reductions in the amounts received or receivable hereunder with respect
       to any Eurodollar Loan because of (x) any change since the Effective Date
       in any applicable law or governmental rule, regulation, order, guideline
       or request (whether or not having the force of law) or in the
       interpretation or administration thereof and including the introduction
       of any new law or governmental rule, regulation, order, guideline or
       request, such as, for example, but not limited to: (A) a change in the
       basis of taxation of payment to any Lender of the principal of or
       interest on the Loans or the Notes or any other amounts payable hereunder
       (except for changes in the rate of tax on, or determined by reference to,
       the net income or profits of such Lender pursuant to the laws of the
       jurisdiction in which it is organized or in which its principal office or
       applicable lending office is located or any subdivision thereof or
       therein) or (B) a change in official reserve requirements, but, in all
       events, excluding reserves required under Regulation D to the extent
       included in the computation of the Eurodollar Rate and/or (y) other
       circumstances occurring since the Effective Date affecting the interbank
       Eurodollar market or the position of such Lender in such market; or



                                      -8-
<PAGE>   14

            (iii) at any time, that the making or continuance of any Eurodollar
       Loan has been made (x) unlawful by any law or governmental rule,
       regulation or order, (y) impossible by compliance by any Lender in good
       faith with any governmental request (whether or not having force of law)
       or (z) impracticable as a result of a contingency occurring after the
       Effective Date which materially and adversely affects the interbank
       Eurodollar market;

then, and in any such event, such Lender (or the Administrative Agent, in the
case of clause (i) above) shall promptly give notice (by telephone promptly
confirmed in writing) to the Borrower and, except in the case of clause (i)
above, to the Administrative Agent of such determination (which notice the
Administrative Agent shall promptly transmit to each of the other Lenders).
Thereafter (x) in the case of clause (i) above, Eurodollar Loans shall no longer
be available until such time as the Administrative Agent notifies the Borrower
and the Lenders that the circumstances giving rise to such notice by the
Administrative Agent no longer exist, and any Notice of Borrowing or Notice of
Conversion given by the Borrower with respect to Eurodollar Loans which have not
yet been incurred (including by way of conversion) shall be deemed rescinded by
the Borrower, (y) in the case of clause (ii) above, the Borrower shall pay to
such Lender, upon such Lender's written request therefor, such additional
amounts (in the form of an increased rate of, or a different method of
calculating, interest or otherwise as such Lender in its sole discretion shall
determine) as shall be required to compensate such Lender for such increased
costs or reductions in amounts received or receivable hereunder (a written
notice as to the additional amounts owed to such Lender, showing in reasonable
detail the basis for the calculation thereof, submitted to the Borrower by such
Lender shall, absent manifest error, be final and conclusive and binding on all
the parties hereto) and (z) in the case of clause (iii) above, the Borrower
shall take one of the actions specified in Section 1.10(b) as promptly as
possible and, in any event, within the time period required by law.

            (b) At any time that any Eurodollar Loan is affected by the
circumstances described in Section 1.10(a)(ii) or (iii), the Borrower may (and
in the case of a Eurodollar Loan affected by the circumstances described in
Section 1.10(a)(iii) the Borrower shall) either (x) if the affected Eurodollar
Loan is then being made initially or pursuant to a conversion, cancel such
Borrowing by giving the Administrative Agent telephonic notice (confirmed in
writing) on the same date that the Borrower was notified by the affected Lender
or the Administrative Agent pursuant to Section 1.10(a)(ii) or (iii) or (y) if
the affected Eurodollar Loan is then outstanding, upon at least three Business
Days' written notice to the Administrative Agent, require the affected Lender to
convert such Eurodollar Loan into a Base Rate Loan, provided that, if more than
one Lender is affected at any time, then all affected Lenders must be treated
the same pursuant to this Section 1.10(b).

            (c) If any Lender determines that after the Effective Date the
introduction of or any change in any applicable law or governmental rule,
regulation, order, guideline, directive or request (whether or not having the
force of law) concerning capital adequacy, or any change in interpretation or
administration thereof by the NAIC or any governmental authority, central bank
or comparable agency, will have the effect of increasing the amount of capital
required or expected to be maintained by such Lender or any corporation
controlling such Lender based on



                                      -9-
<PAGE>   15

the existence of such Lender's Commitment hereunder or its obligations
hereunder, then the Borrower shall pay to such Lender, upon its written demand
therefor, such additional amounts as shall be required to compensate such Lender
or such other corporation for the increased cost to such Lender or such other
corporation or the reduction in the rate of return to such Lender or such other
corporation as a result of such increase of capital. In determining such
additional amounts, each Lender will act reasonably and in good faith and will
use averaging and attribution methods which are reasonable, provided that such
Lender's determination of compensation owing under this Section 1.10(c) shall,
absent manifest error, be final and conclusive and binding on all the parties
hereto. Each Lender, upon determining that any additional amounts will be
payable pursuant to this Section 1.10(c), will give prompt written notice
thereof to the Borrower, which notice shall show in reasonable detail the basis
for calculation of such additional amounts.

            1.11 Compensation. The Borrower shall compensate each Lender, upon
its written request (which request shall set forth in reasonable detail the
basis for requesting such compensation), for all losses, expenses and
liabilities (including, without limitation, any loss, expense or liability
incurred by reason of the liquidation or reemployment of deposits or other funds
required by such Lender to fund its Eurodollar Loans but excluding loss of
anticipated profits) which such Lender may sustain: (i) if for any reason (other
than a default by such Lender or the Administrative Agent) a Borrowing of, or
conversion from or into, Eurodollar Loans does not occur on a date specified
therefor in a Notice of Borrowing or Notice of Conversion (whether or not
withdrawn by the Borrower or deemed withdrawn pursuant to Section 1.10(a)); (ii)
if any repayment (including any repayment made pursuant to Section 4.01, Section
4.02 or as a result of an acceleration of the Loans pursuant to Section 10) or
conversion of any of its Eurodollar Loans occurs on a date which is not the last
day of an Interest Period with respect thereto; (iii) if any prepayment of any
of its Eurodollar Loans is not made on any date specified in a notice of
prepayment given by the Borrower; or (iv) as a consequence of (x) any other
default by the Borrower to repay its Eurodollar Loans when required by the terms
of this Agreement or any Note held by such Lender or (y) any election made
pursuant to Section 1.10(b).

            1.12 Change of Lending Office. Each Lender agrees that upon the
occurrence of any event giving rise to the operation of Section 1.10(a)(ii) or
(iii), Section 1.10(c), Section 2.06 or Section 4.04 with respect to such
Lender, it will, if requested by the Borrower, use reasonable efforts (subject
to overall policy considerations of such Lender) to designate another lending
office for any Loans or Letters of Credit affected by such event, provided that
such designation is made on such terms that such Lender and its lending office
suffer no economic, legal or regulatory disadvantage, with the object of
avoiding the consequence of the event giving rise to the operation of such
Section. Nothing in this Section 1.12 shall affect or postpone any of the
obligations of the Borrower or the right of any Lender provided in Sections
1.10, 2.06 and 4.04.

            1.13 Replacement of Lenders. (x) If any Lender becomes a Defaulting
Lender or otherwise defaults in its obligations to make Loans, (y) upon the
occurrence of an event giving rise to the operation of Section 1.10(a)(ii) or
(iii), Section 1.10(c), Section 2.06 or Section 4.04 with respect to any Lender
which results in such Lender charging to the Borrower increased costs in excess
of those being generally charged by the other Lenders or (z) in the case of a
refusal by a



                                      -10-
<PAGE>   16

Lender to consent to certain proposed changes, waivers, discharges or
terminations with respect to this Agreement which have been approved by the
Required Lenders as (and to the extent) provided in Section 13.12(b), the
Borrower shall have the right, if no Default or Event of Default then exists
(or, in the case of preceding clause (z), no Default or Event of Default will
exist immediately after giving effect to such replacement), to replace such
Lender (the "Replaced Lender") with one or more other Eligible Transferees, none
of whom shall constitute a Defaulting Lender at the time of such replacement
(collectively, the "Replacement Lender") and each of whom shall be required to
be reasonably acceptable to the Administrative Agent, provided that (i) at the
time of any replacement pursuant to this Section 1.13, the Replacement Lender
shall enter into one or more Assignment and Assumption Agreements pursuant to
Section 13.04(b) (and with all fees payable pursuant to said Section 13.04(b) to
be paid by the Replacement Lender) pursuant to which the Replacement Lender
shall acquire the Commitment and all outstanding Revolving Loans of, and
participations in Letters of Credit by, the Replaced Lender and, in connection
therewith, shall pay to (x) the Replaced Lender in respect thereof an amount
equal to the sum of (I) an amount equal to the principal of, and all accrued
interest on, all outstanding Revolving Loans of the Replaced Lender, (II) an
amount equal to all Unpaid Drawings that have been funded by (and not reimbursed
to) such Replaced Lender, together with all then unpaid interest with respect
thereto at such time and (III) an amount equal to all accrued, but theretofore
unpaid, Fees owing to the Replaced Lender pursuant to Section 3.01, (y) each
Issuing Lender an amount equal to such Replaced Lender's Percentage of any
Unpaid Drawing (which at such time remains an Unpaid Drawing) to the extent such
amount was not theretofore funded by such Replaced Lender to such Issuing Lender
and (z) the Swingline Lender an amount equal to such Replaced Lender's
Percentage of any Mandatory Borrowings to the extent such amount was not
theretofore funded by such Replaced Lender to the Swingline Lender and (ii) all
obligations of the Borrower due and owing to the Replaced Lender at such time
(other than those specifically described in clause (i) above in respect of which
the assignment purchase price has been, or is concurrently being, paid) shall be
paid in full to such Replaced Lender concurrently with such replacement. Upon
the execution of the respective Assignment and Assumption Agreement, the payment
of amounts referred to in clauses (i) and (ii) above and, if so requested by the
Replacement Lender, delivery to the Replacement Lender of the appropriate
Revolving Note executed by the Borrower, the Replacement Lender shall become a
Lender hereunder and the Replaced Lender shall cease to constitute a Lender
hereunder, except with respect to indemnification provisions under this
Agreement (including, without limitation, Sections 1.10, 1.11, 2.06, 4.04, 12.06
and 13.01), which shall survive as to such Replaced Lender.

            SECTION 2. Letters of Credit.

            2.01 Letters of Credit. (a) Subject to and upon the terms and
conditions set forth herein, the Borrower may request that an Issuing Lender
issue, at any time and from time to time on and after the Effective Date and
prior to the 30th day prior to the Final Maturity Date, for the account of the
Borrower and for the benefit of (x) any holder (or any trustee, agent or other
similar representative for any such holders) of L/C Supportable Obligations of
the Borrower or any of its Subsidiaries, an irrevocable standby letter of
credit, in a form customarily used by such Issuing Lender or in such other form
as has been approved by such Issuing Lender and (y) sellers of goods to the

form

customarily used by such Issuing Lender or in such other form as has been
approved by such Issuing Lender (each such letter of credit issued pursuant to
this Section 2.01, a "Letter of Credit" and, collectively, the "Letters of
Credit"). All Letters of Credit shall be denominated in Dollars and shall be
issued on a sight basis only.

            (b) Subject to and upon the terms and conditions set forth herein,
each Issuing Lender agrees that it will, at any time and from time to time on
and after the Effective Date and prior to the 30th day prior to the Final
Maturity Date, following its receipt of the respective Letter of Credit Request,
issue for the account of the Borrower, one or more Letters of Credit as are
permitted to remain outstanding hereunder without giving rise to a Default or an
Event of Default, provided that no Issuing Lender shall be under any obligation
to issue any Letter of Credit of the types described above if at the time of
such issuance:

            (i) any order, judgment or decree of any governmental authority or
       arbitrator shall purport by its terms to enjoin or restrain such Issuing
       Lender from issuing such Letter of Credit or any requirement of law
       applicable to such Issuing Lender or any request or directive (whether or
       not having the force of law) from any governmental authority with
       jurisdiction over such Issuing Lender shall prohibit, or request that
       such Issuing Lender refrain from, the issuance of letters of credit
       generally or such Letter of Credit in particular or shall impose upon
       such Issuing Lender with respect to such Letter of Credit any restriction
       or reserve or capital requirement (for which such Issuing Lender is not
       otherwise compensated) not in effect on the Effective Date, or any
       unreimbursed loss, cost or expense which was not applicable or in effect
       with respect to such Issuing Lender as of the date hereof; or

            (ii) such Issuing Lender shall have received from the Borrower or
       the Required Lenders prior to the issuance of such Letter of Credit
       notice of the type described in the second sentence of Section 2.03(b).

            2.02 Maximum Letter of Credit Outstandings; Final Maturities.
Notwithstanding anything to the contrary contained in this Agreement, (i) no
Letter of Credit shall be issued the Stated Amount of which, when added to the
Letter of Credit Outstandings (exclusive of Unpaid Drawings which are repaid on
the date of, and prior to the issuance of, the respective Letter of Credit) at
such time would exceed either (x) $150,000,000 or (y) when added to the sum of
(I) the aggregate principal amount of all Revolving Loans then outstanding and
(II) the aggregate principal amount of all Swingline Loans then outstanding, an
amount equal to the Total Available Commitment at such time and (ii) each Letter
of Credit shall by its terms terminate on or before (x) in the case of standby
Letters of Credit, the earlier of (A) the date which occurs 12 months after the
date of the issuance thereof (although any such standby Letter of Credit may be
extendible for successive periods of up to 12 months, but not beyond the third
Business Day prior to the Final Maturity Date, on terms acceptable to such
Issuing Lender) and (B) three Business Days prior to the Final Maturity Date and
(y) in the case of trade Letters of Credit, the earlier of (A) the date which
occurs 180 days after the date of issuance thereof and (B) 15 days prior to the
Final Maturity Date.



                                      -12-

            2.03 Letter of Credit Requests; Minimum Stated Amount. (a) Whenever
the Borrower desires that a Letter of Credit be issued for its account, the
Borrower shall give the Administrative Agent and the respective Issuing Lender
at least five Business Days' (or such shorter period as is acceptable to such
Issuing Lender) written notice thereof. Each notice shall be in the form of
Exhibit C appropriately completed (each a "Letter of Credit Request").

            (b) The making of each Letter of Credit Request shall be deemed to
be a representation and warranty by the Borrower that such Letter of Credit may
be issued in accordance with, and will not violate the requirements of, Section
2.02. Unless the respective Issuing Lender has received notice from the Borrower
or the Required Lenders before it issues a Letter of Credit that one or more of
the conditions specified in Section 6 are not then satisfied, or that the
issuance of such Letter of Credit would violate Section 2.02, then such Issuing
Lender shall, subject to the terms and conditions of this Agreement, issue the
requested Letter of Credit for the account of the Borrower in accordance with
such Issuing Lender's usual and customary practices. Upon its issuance of or
amendment to any standby Letter of Credit, the respective Issuing Lender shall
promptly notify the Borrower, each Participant and the Administrative Agent of
such issuance or amendment and such notification shall be accompanied by a copy
of the issued Letter of Credit or amendment. Notwithstanding anything to the
contrary contained in this Agreement, in the event that a Lender Default exists,
no Issuing Lender shall be required to issue any Letter of Credit unless such
Issuing Lender has entered into an arrangement satisfactory to it and the
Borrower to eliminate such Issuing Lender's risk with respect to the
participation in Letters of Credit by the Defaulting Lender or Lenders,
including by cash collateralizing such Defaulting Lender's or Lenders'
Percentage of the Letter of Credit Outstandings.

            (c) The initial Stated Amount of each Letter of Credit shall not be
less than $1,000,000 or such lesser amount as is acceptable to the respective
Issuing Lender.

            2.04 Letter of Credit Participations. (a) Immediately upon the
issuance by each Issuing Lender of any Letter of Credit, such Issuing Lender
shall be deemed to have sold and transferred to each Lender, other than such
Issuing Lender (each such Lender, in its capacity under this Section 2.04, a
"Participant"), and each such Participant shall be deemed irrevocably and
unconditionally to have purchased and received from such Issuing Lender, without
recourse or warranty, an undivided interest and participation, to the extent of
such Participant's Percentage, in such Letter of Credit, each drawing or payment
made thereunder and the obligations of the Borrower under this Agreement with
respect thereto, and any security therefor or guaranty pertaining thereto. Upon
any change in the Commitments or Percentages of the Lenders pursuant to Section
1.13 or 13.04, it is hereby agreed that, with respect to all outstanding Letters
of Credit and Unpaid Drawings, there shall be an automatic adjustment to the
participations pursuant to this Section 2.04 to reflect the new Percentages of
the assignor and assignee Lender, as the case may be.

            (b) In determining whether to pay under any Letter of Credit issued
by it, no Issuing Lender shall have an obligation relative to the other Lenders
other than to confirm that any documents required to be delivered under such
Letter of Credit appear to have been delivered

                                      -13-
<PAGE>   19

and that they appear to substantially comply on their face with the requirements
of such Letter of Credit. Any action taken or omitted to be taken by any Issuing
Lender under or in connection with any Letter of Credit issued by it shall not
create for such Issuing Lender any resulting liability to the Borrower, any
other Credit Party, any Lender or any other Person unless taken or omitted by
reason of the gross negligence or willful misconduct of such Issuing Lender (as
determined by a court of competent jurisdiction in a final and non-appealable
decision).

            (c) In the event that any Issuing Lender makes any payment under any
Letter of Credit issued by it and the Borrower shall not have reimbursed such
amount in full to such Issuing Lender pursuant to Section 2.05(a), such Issuing
Lender shall promptly notify the Administrative Agent, which shall promptly
notify each Participant of such failure, and each Participant shall promptly and
unconditionally pay to such Issuing Lender the amount of such Participant's
Percentage of such unreimbursed payment in Dollars and in same day funds. If the
Administrative Agent so notifies, prior to 12:00 Noon (Detroit, Michigan time)
on any Business Day, any Participant required to fund a payment under a Letter
of Credit, such Participant shall make available to the respective Issuing
Lender in Dollars such Participant's Percentage of the amount of such payment on
such Business Day in same day funds; provided, however, that no Participant
shall be obligated to pay to the respective Issuing Lender its Percentage of
such unreimbursed amount for any wrongful payment made by such Issuing Lender
under a Letter of Credit issued by it as a result of acts or omissions
constituting willful misconduct or gross negligence on the part of such Issuing
Lender (as determined by a court of competent jurisdiction in a final and
non-appealable decision). If and to the extent such Participant shall not have
so made its Percentage of the amount of such payment available to the respective
Issuing Lender, such Participant agrees to pay to such Issuing Lender, forthwith
on demand such amount, together with interest thereon, for each day from such
date until the date such amount is paid to such Issuing Lender at the overnight
Federal Funds Rate for the first three days and at the interest rate applicable
to Base Rate Loans for each day thereafter. The failure of any Participant to
make available to the respective Issuing Lender its Percentage of any payment
under any Letter of Credit shall not relieve any other Participant of its
obligation hereunder to make available to the respective Issuing Lender its
Percentage of any payment under any Letter of Credit on the date required, as
specified above, but no Participant shall be responsible for the failure of any
other Participant to make available to such Issuing Lender such other
Participant's Percentage of any such payment.

            (d) Whenever an Issuing Lender receives a payment of a reimbursement
obligation as to which it has received any payments from the Participants
pursuant to clause (c) above, such Issuing Lender shall pay to each Participant
which has paid its Percentage thereof, in Dollars and in same day funds, an
amount equal to such Participant's share (based upon the proportionate aggregate
amount originally funded by such Participant to the aggregate amount funded by
all Participants) of the principal amount of such reimbursement obligation and
interest thereon accruing after the purchase of the respective participations.

            (e) Upon the request of any Participant, each Issuing Lender shall
furnish to such Participant copies of any Letter of Credit issued by it and such
other documentation as may reasonably be requested by such Participant.

<PAGE>   20

            (f) The obligations of the Participants to make payments to each
Issuing Lender with respect to Letters of Credit issued by it shall be
irrevocable and not subject to any qualification or exception whatsoever (except
as otherwise provided in the proviso to the second sentence of Section 2.04(c))
and shall be made in accordance with the terms and conditions of this Agreement
under all circumstances, including, without limitation, any of the following
circumstances:

            (i) any lack of validity or enforceability of this Agreement or any
       of the other Credit Documents;

            (ii) the existence of any claim, setoff, defense or other right
       which the Borrower or any of its Subsidiaries may have at any time
       against a beneficiary named in a Letter of Credit, any transferee of any
       Letter of Credit (or any Person for whom any such transferee may be
       acting), the Agents, any Issuing Lender, any Participant or any other
       Person, whether in connection with this Agreement, any Letter of Credit,
       the transactions contemplated herein or any unrelated transactions
       (including any underlying transaction between the Borrower or any
       Subsidiary of the Borrower and the beneficiary named in any such Letter
       of Credit);

            (iii) any draft, certificate or any other document presented under
       any Letter of Credit proving to be forged, fraudulent, invalid or
       insufficient in any respect or any statement therein being untrue or
       inaccurate in any respect;

            (iv) the surrender or impairment of any security for the performance
       or observance of any of the terms of any of the Credit Documents; or

            (v) the occurrence of any Default or Event of Default.

            2.05 Agreement to Repay Letter of Credit Drawings. (a) The Borrower
agrees to reimburse each Issuing Lender, by making payment to the Administrative
Agent in Dollars and in immediately available funds at the Payment Office, for
any payment or disbursement made by such Issuing Lender under any Letter of
Credit issued by it (each such amount, so paid until reimbursed, an "Unpaid
Drawing"), not later than one Business Day following receipt by the Borrower of
notice of such payment or disbursement (provided that no such notice shall be
required to be given if a Default or an Event of Default under Section 10.05
shall have occurred and be continuing, in which case the Unpaid Drawing shall be
due and payable immediately without presentment, demand, protest or notice of
any kind (all of which are hereby waived by the Borrower)), with interest on the
amount so paid or disbursed by such Issuing Lender, to the extent not reimbursed
prior to 12:00 Noon (Detroit, Michigan time) on the date of such payment or
disbursement, from and including the date paid or disbursed to but excluding the
date such Issuing Lender was reimbursed by the Borrower therefor at a rate per
annum which shall be the sum of the Applicable Margin for Base Rate Loans plus
the Base Rate each as in effect from time to time; provided, however, to the
extent such amounts are not reimbursed prior to 12:00 Noon (Detroit, Michigan
time) on the third Business Day following the receipt by the Borrower of notice
of such payment or disbursement or following the occurrence of a Default or an
Event of Default under Section 10.05, interest shall thereafter accrue on the
amounts so paid or disbursed


                                      -15-
<PAGE>   21

by such Issuing Lender (and until reimbursed by the Borrower) at a rate per
annum which shall be the sum of the Applicable Margin for Base Rate Loans plus
the Base Rate each as in effect from time to time plus 2%, in each such case,
with interest to be payable on demand. Each Issuing Lender shall give the
Borrower prompt written notice of each Drawing under any Letter of Credit issued
by it, provided that the failure to give any such notice shall in no way affect,
impair or diminish the Borrower's obligations hereunder.

            (b) The obligations of the Borrower under this Section 2.05 to
reimburse each Issuing Lender with respect to Unpaid Drawings (including, in
each case, interest thereon) shall be absolute and unconditional under any and
all circumstances and irrespective of any setoff, counterclaim or defense to
payment which the Borrower may have or have had against any Lender (including in
its capacity as issuer of the Letter of Credit or as Participant), including,
without limitation, any defense based upon the failure of any drawing or payment
under a Letter of Credit (each a "Drawing") to conform to the terms of the
Letter of Credit or any nonapplication or misapplication by the beneficiary of
the proceeds of such Drawing; provided, however, that the Borrower shall not be
obligated to reimburse the respective Issuing Lender for any wrongful payment
made by such Issuing Lender under a Letter of Credit issued by it as a result of
acts or omissions constituting willful misconduct or gross negligence on the
part of such Issuing Lender (as determined by a court of competent jurisdiction
in a final and non-appealable decision).

            2.06 Increased Costs. If at any time after the Effective Date, the
introduction of or any change in any applicable law, rule, regulation, order,
guideline or request or in the interpretation or administration thereof by the
NAIC or any governmental authority charged with the interpretation or
administration thereof, or compliance by any Issuing Lender or any Participant
with any request or directive by the NAIC or by any such governmental authority
(whether or not having the force of law), shall either (i) impose, modify or
make applicable any reserve, deposit, capital adequacy or similar requirement
against letters of credit issued by any Issuing Lender or participated in by any
Participant, or (ii) impose on any Issuing Lender or any Participant any other
conditions relating, directly or indirectly, to this Agreement; and the result
of any of the foregoing is to increase the cost to any Issuing Lender or any
Participant of issuing, maintaining or participating in any Letter of Credit, or
reduce the amount of any sum received or receivable by any Issuing Lender or any
Participant hereunder or reduce the rate of return on its capital with respect
to Letters of Credit (except for changes in the rate of tax on, or determined by
reference to, the net income or profits of such Issuing Lender or such
Participant pursuant to the laws of the jurisdiction in which it is organized or
in which its principal office or applicable lending office is located or any
subdivision thereof or therein), then, upon the delivery of the certificate
referred to below to the Borrower by such Issuing Lender or such Participant (a
copy of which certificate shall be sent by such Issuing Lender or such
Participant to the Administrative Agent), the Borrower shall pay to such Issuing
Lender or such Participant such additional amount or amounts as will compensate
such Issuing Lender or such Participant for such increased cost or reduction in
the amount receivable or reduction on the rate of return on its capital. Each
Issuing Lender or Participant, upon determining that any additional amounts will
be payable to it pursuant to this Section 2.06, will give prompt written notice
thereof to the Borrower, which notice shall include a certificate submitted to
the Borrower by such Issuing



                                      -16-
<PAGE>   22
Lender or such Participant (a copy of which certificate shall be sent by such
Issuing Lender or such Participant to the Administrative Agent), setting forth
in reasonable detail the basis for the calculation of such additional amount or
amounts necessary to compensate such Issuing Lender or such Participant. The
certificate required to be delivered pursuant to this Section 2.06 shall, absent
manifest error, be final and conclusive and binding on the Borrower.


            SECTION 3. Fees; Reductions of Commitment.

            3.01 Fees. (a) The Borrower agrees to pay to the Administrative
Agent, for distribution to each Non-Defaulting Lender, a commitment commission
(the "Commitment Commission") for the period from and including the Effective
Date to but excluding the Final Maturity Date (or such earlier date on which the
Total Commitment shall have been terminated), computed at a rate for each day
equal to the Applicable Commitment Commission Percentage on the average daily
amount of such Lender's Unutilized Commitment. Accrued Commitment Commission
shall be due and payable quarterly in arrears on each Quarterly Payment Date and
on the Final Maturity Date (or such earlier date on which the Total Commitment
shall have been terminated).

            (b) The Borrower agrees to pay to the Administrative Agent for
distribution to each Lender (based on each such Lender's respective Percentage)
a fee in respect of each Letter of Credit issued hereunder (the "Letter of
Credit Fee") for the period from and including the date of issuance of such
Letter of Credit to and including the date of termination or expiration of such
Letter of Credit, computed at a rate per annum equal to the Applicable Margin
then in effect with respect to Eurodollar Loans on the daily Stated Amount of
such Letter of Credit. Accrued Letter of Credit Fees shall be due and payable
quarterly in arrears on each Quarterly Payment Date and on the first day on or
after the termination of the Total Commitment upon which no Letters of Credit
remain outstanding.

            (c) The Borrower agrees to pay to each Issuing Lender, for its own
account, a facing fee in respect of each Letter of Credit issued hereunder by
such Issuing Lender (the "Facing Fee") for the period from and including the
date of issuance of such Letter of Credit to and including the date of the
termination or expiration of such Letter of Credit, computed at a rate per annum
equal to 1/8 of 1% on the daily Stated Amount of such Letter of Credit. Accrued
Facing Fees shall be due and payable quarterly in arrears on each Quarterly
Payment Date and upon the first day on or after the termination of the Total
Commitment upon which no Letters of Credit remain outstanding.

            (d) The Borrower agrees to pay to each Issuing Lender, for its own
account, upon each payment under, issuance of, or amendment to, any Letter of
Credit issued by such Issuing Lender, such amount as shall at the time of such
event be the administrative charge and the reasonable expenses which such
Issuing Lender is generally imposing in connection with such occurrence with
respect to letters of credit issued by it.

            (e) The Borrower agrees to pay to the Agents, for their own
accounts, such other fees as have been agreed to in writing by the Borrower and
the Agents.

            3.02 Voluntary Termination of Unutilized Commitments. (a) Upon at
least three Business Days' prior written notice to the Administrative Agent at
the Notice Office (which notice the Administrative Agent shall promptly transmit
to each of the Lenders), the Borrower shall have the right, at any time or from
time to time, without premium or penalty, to terminate the Total Unutilized
Commitment in whole, or reduce it in part, pursuant to this Section 3.02(a), in
a minimum amount of $5,000,000 or an integral multiple of $1,000,000 in excess
thereof in the case of partial reductions to the Total Unutilized Commitment,
provided that (i) each such reduction shall apply to reduce the remaining
Scheduled Commitment Reductions on a pro rata basis (based upon the amount of
each such remaining Scheduled Commitment Reduction after giving effect to all
prior reductions thereto) and (ii) each such reduction shall apply
proportionately to permanently reduce the Commitment of each Lender.

            (b) In the event of a refusal by a Lender to consent to certain
proposed changes, waivers, discharges or terminations with respect to this
Agreement which have been approved by the Required Lenders as (and to the
extent) provided in Section 13.12(b), the Borrower may, subject to its
compliance with the requirements of Section 13.12(b), upon five Business Days'
prior written notice to the Administrative Agent at the Notice Office (which
notice the Administrative Agent shall promptly transmit to each of the Lenders)
terminate the Commitment of such Lender, so long as all Loans, together with
accrued and unpaid interest, Fees and all other amounts, owing to such Lender
are repaid concurrently with the effectiveness of such termination pursuant to
Section 4.01(b) (at which time Schedule I shall be deemed modified to reflect
such changed amounts), and at such time, such Lender shall no longer constitute
a "Lender" for purposes of this Agreement, except with respect to
indemnifications under this Agreement (including, without limitation, Sections
1.10, 1.11, 2.06, 4.04, 12.06 and 13.01), which shall survive as to such repaid
Lender.

            3.03 Mandatory Reduction of Commitments. (a) The Total Commitment
(and the Commitment of each Lender) shall terminate in its entirety on September
15, 1999 unless the Effective Date has occurred on or before such date.

            (b) In addition to any other mandatory commitment reductions
pursuant to this Section 3.03, but subject to reduction as provided in clause
(i) of the proviso set forth in Section 3.02(a) and as provided in clauses (c)
and (d) of this Section 3.03, on each date set forth below, the Total Commitment
shall be permanently reduced by the amount set forth opposite each such date
below (each reduction required by this Section 3.03(b), a "Scheduled Commitment
Reduction"):

</TABLE>

            (c) In addition to any other mandatory commitment reductions
pursuant to this Section 3.03, on October 15, 1999 (or such earlier date, if
any, on which the Borrower has notified the Agents in writing that the Borrower
is no longer pursuing the DPRC Acquisition),



                                      -18-
<PAGE>   24

the Total Commitment shall be permanently reduced by $470,000,000 unless the
DPRC Acquisition Date has occurred by such date.

            (d) In addition to any other mandatory commitment reductions
pursuant to this Section 3.03, on each date on which the Borrower incurs any
Indebtedness pursuant to Section 9.04(xiii), the Total Commitment shall be
permanently reduced by an amount equal to 50% of the cash proceeds received from
the respective incurrence of Indebtedness (net of underwriting discounts and
commissions and other reasonable costs associated therewith).

            (e) In addition to any other mandatory commitment reductions
pursuant to this Section 3.03, on the date on which the Borrower consummates a
Sale-Leaseback Transaction with respect to the Farmington Hills Property and on
the 180th day following the consummation of each other Sale-Leaseback
Transaction pursuant to Section 9.02 (except for temporary leases for a term,
including any renewal thereof, of not more than one year and except for leases
between the Borrower and one or more Subsidiaries of the Borrower or between
Subsidiaries of the Borrower), the Total Commitment shall be permanently reduced
by an amount equal to the Value of each such Sale-Leaseback Transaction,
provided that in the case of a Sale-Leaseback Transaction other than with
respect to the Farmington Hills Property, the Total Commitment only shall be
reduced to the extent, but only to the extent, that such amount has not
otherwise been reinvested within such 180-day period and/or used to effect a
permanent reduction in the Total Commitment pursuant to Section 3.02(a) as
provided in Section 9.02.

            (f) In addition to any other mandatory commitment reductions
pursuant to this Section 3.03, the Total Commitment (and the Commitment of each
Lender) shall terminate in its entirety on the Final Maturity Date.

            (g) Each reduction to the Total Commitment pursuant to clauses (c),
(d) and (e) of this Section 3.03 shall be applied to reduce the then remaining
Scheduled Commitment Reductions on a pro rata basis (based upon the amount of
each such remaining Scheduled Commitment Reduction after giving effect to all
prior reductions thereto). In addition, each reduction to the Total Commitment
pursuant to this Section 3.03 shall be applied proportionately to permanently
reduce the Commitment of each Lender.

            SECTION 4. Prepayments; Payments; Taxes.

            4.01 Voluntary Prepayments. (a) The Borrower shall have the right to
prepay the Loans, without premium or penalty, in whole or in part at any time
and from time to time on the following terms and conditions: (i) the Borrower
shall give the Administrative Agent prior to 12:00 Noon (Detroit, Michigan time)
at the Notice Office (x) at least one Business Day's prior written notice (or
telephonic notice promptly confirmed in writing) of its intent to prepay Base
Rate Loans (or same day notice in the case of a prepayment of Swingline Loans)
and (y) at least three Business Days' prior written notice (or telephonic notice
promptly confirmed in writing) of its intent to prepay Eurodollar Loans, the
amount of such prepayment and the Types of Loans to be prepaid and, in the case
of Eurodollar Loans, the specific Borrowing or Borrowings pursuant to which
made, which notice the Administrative Agent shall, except in the case of
Swingline Loans, promptly transmit to each of the Lenders; (ii) (x) each partial
prepayment of Revolving



                                      -19-
<PAGE>   25

Loans pursuant to this Section 4.01(a) shall be in an aggregate principal amount
of at least $5,000,000 and (y) each partial prepayment of Swingline Loans
pursuant to this Section 4.01(a) shall be in an aggregate principal amount of at
least $1,000,000, provided that if any partial prepayment of Eurodollar Loans
made pursuant to any Borrowing shall reduce the outstanding principal amount of
Eurodollar Loans made pursuant to such Borrowing to an amount less than the
Minimum Borrowing Amount applicable thereto, then such Borrowing shall be
converted at the end of the then current Interest Period into a Borrowing of
Base Rate Loans; and (iii) each prepayment pursuant to this Section 4.01(a) in
respect of any Revolving Loans made pursuant to a Borrowing shall be applied pro
rata among such Revolving Loans, provided that at the Borrower's election in
connection with any prepayment of Revolving Loans pursuant to this Section
4.01(a), such prepayment shall not, so long as no Default or Event of Default
then exists, be applied to any Revolving Loan of a Defaulting Lender.

            (b) In the event of a refusal by a Lender to consent to certain
proposed changes, waivers, discharges or terminations with respect to this
Agreement which have been approved by the Required Lenders as (and to the
extent) provided in Section 13.12(b), the Borrower may, upon five Business Days'
prior written notice to the Administrative Agent at the Notice Office (which
notice the Administrative Agent shall promptly transmit to each of the Lenders),
repay all Revolving Loans of such Lender, together with accrued and unpaid
interest, Fees and other amounts owing to such Lender in accordance with, and
subject to the requirements of, said Section 13.12(b) so long as (A) the
Commitment of such Lender is terminated concurrently with such repayment
pursuant to Section 3.02(b) (at which time Schedule I shall be deemed modified
to reflect the changed Commitments) and (B) the consents, if any, required under
Section 13.12(b) in connection with the repayment pursuant to this clause (b)
have been obtained.

            4.02 Mandatory Repayments. (a) On any day on which the sum of (I)
the aggregate outstanding principal amount of all Revolving Loans (after giving
effect to all other repayments thereof on such date), (II) the aggregate
outstanding principal amount of all Swingline Loans (after giving effect to all
other repayments thereof on such date) and (III) the aggregate amount of all
Letter of Credit Outstandings exceeds the Total Available Commitment as then in
effect, the Borrower shall prepay on such day the principal of Swingline Loans
and, after all Swingline Loans have been repaid in full or if no Swingline Loans
are outstanding, Revolving Loans in an amount equal to such excess. If, after
giving effect to the prepayment of all outstanding Swingline Loans and Revolving
Loans, the aggregate amount of the Letter of Credit Outstandings exceeds the
Total Available Commitment as then in effect, the Borrower shall pay to the
Administrative Agent at the Payment Office on such day an amount of cash and/or
Cash Equivalents equal to the amount of such excess (up to a maximum amount
equal to the Letter of Credit Outstandings at such time), such cash and/or Cash
Equivalents to be held as security for all obligations of the Borrower to the
Issuing Lenders and the Lenders hereunder in a cash collateral account to be
established by the Administrative Agent.

            (b) With respect to each repayment of Revolving Loans required by

                                      -20-
<PAGE>   26

provided that: (i) repayments of Eurodollar Loans pursuant to this Section 4.02
may only be made on the last day of an Interest Period applicable thereto unless
all Eurodollar Loans with Interest Periods ending on such date of required
repayment and all Base Rate Loans have been paid in full; (ii) if any repayment
of Eurodollar Loans made pursuant to a single Borrowing shall reduce the
outstanding Eurodollar Loans made pursuant to such Borrowing to an amount less
than the Minimum Borrowing Amount applicable thereto, such Borrowing shall be
converted at the end of the then current Interest Period into a Borrowing of
Base Rate Loans; and (iii) each repayment of any Revolving Loans made pursuant
to a Borrowing shall be applied pro rata among such Revolving Loans. In the
absence of a designation by the Borrower as described in the preceding sentence,
the Administrative Agent shall, subject to the above, make such designation in
its sole discretion.

            (c) Notwithstanding anything to the contrary contained in this
Agreement or in any other Credit Document, (i) all then outstanding Revolving
Loans shall be repaid in full on the Final Maturity Date and (ii) all then
outstanding Swingline Loans shall be repaid in full on the Swingline Expiry
Date.

            4.03 Method and Place of Payment. Except as otherwise specifically
provided herein, all payments under this Agreement or under any Note shall be
made to the Administrative Agent for the account of the Lender or Lenders
entitled thereto not later than 12:00 Noon (Detroit, Michigan time) on the date
when due and shall be made in Dollars in immediately available funds at the
Payment Office. Whenever any payment to be made hereunder or under any Note
shall be stated to be due on a day which is not a Business Day, the due date
thereof shall be extended to the next succeeding Business Day and, with respect
to payments of principal, interest shall be payable at the applicable rate
during such extension.

            4.04 Net Payments. (a) All payments made by the Borrower hereunder
or under any Note will be made without setoff, counterclaim or other defense.
Except as provided in Section 4.04(b), all such payments will be made free and
clear of, and without deduction or withholding for, any present or future taxes,
levies, imposts, duties, fees, assessments or other charges of whatever nature
now or hereafter imposed by any jurisdiction or by any political subdivision or
taxing authority thereof or therein with respect to such payments (but
excluding, except as provided in the second succeeding sentence, any tax imposed
on or measured by the net income or profits of a Lender pursuant to the laws of
the jurisdiction in which it is organized or the jurisdiction in which the
principal office or applicable lending office of such Lender is located or any
subdivision thereof or therein) and all interest, penalties or similar
liabilities with respect to such non-excluded taxes, levies, imposts, duties,
fees, assessments or other charges (all such non-excluded taxes, levies,
imposts, duties, fees, assessments or other charges being referred to
collectively, as "Taxes"). If any Taxes are so levied or imposed, the Borrower
agrees to pay the full amount of such Taxes, and such additional amounts as may
be necessary so that every payment of all amounts due under this Agreement or
under any Note, after withholding or deduction for or on account of any Taxes,
will not be less than the amount provided for herein or in such Note. If any
amounts are payable in respect of Taxes pursuant to the preceding sentence, the
Borrower agrees to reimburse each Lender, upon the written request of such
Lender, for taxes imposed on or measured by the net income or profits of such
Lender pursuant to the laws of the



                                      -21-
<PAGE>   27

jurisdiction in which such Lender is organized or in which the principal office
or applicable lending office of such Lender is located or under the laws of any
political subdivision or taxing authority of any such jurisdiction in which such
Lender is organized or in which the principal office or applicable lending
office of such Lender is located and for any withholding of taxes as such Lender
shall determine are payable by, or withheld from, such Bank, in respect of such
amounts so paid to or on behalf of such Lender pursuant to the preceding
sentence and in respect of any amounts paid to or on behalf of such Lender
pursuant to this sentence. The Borrower will furnish to the Administrative Agent
within 45 days after the date the payment of any Taxes is due pursuant to
applicable law certified copies of tax receipts evidencing such payment by the
Borrower. The Borrower agrees to indemnify and hold harmless each Lender, and
reimburse such Lender upon its written request, for the amount of any Taxes so
levied or imposed and paid by such Lender.

            (b) Each Lender that is not a United States person (as such term is
defined in Section 7701(a)(30) of the Code) for U.S. Federal income tax purposes
agrees to deliver to the Borrower and the Administrative Agent on or prior to
the Effective Date, or in the case of a Lender that is an assignee or transferee
of an interest under this Agreement pursuant to Section 1.13 or 13.04 (unless
the respective Lender was already Lender hereunder immediately prior to such
assignment or transfer), on the date of such assignment or transfer to such
Lender, (i) two accurate and complete original signed copies of Internal Revenue
Service Form W-8ECI or Form W-8BEN (with respect to a complete exemption under
an income tax treaty) (or successor forms) certifying to such Lender's
entitlement as of such date to a complete exemption from United States
withholding tax with respect to payments to be made under this Agreement and
under any Note, or (ii) if the Lender is not a "bank" within the meaning of
Section 881(c)(3)(A) of the Code and cannot deliver either Internal Revenue
Service Form W-8ECI or Form W-8BEN (with respect to a complete exemption under
an income tax treaty) (or any successor forms) pursuant to clause (i) above, (x)
a certificate substantially in the form of Exhibit D (any such certificate, a
"Section 4.04(b)(ii) Certificate") and (y) two accurate and complete original
signed copies of Internal Revenue Service Form W-8BEN (with respect to the
portfolio exemption) (or successor form) certifying to such Lender's entitlement
as of such date to a complete exemption from United States withholding tax with
respect to payments of interest to be made under this Agreement and under any
Note. In addition, each Lender agrees that from time to time after the Effective
Date, when a lapse in time or change in circumstances renders the previous
certification obsolete or inaccurate in any material respect, such Lender will
deliver to the Borrower and the Administrative Agent two new accurate and
complete original signed copies of Internal Revenue Service Form W-8ECI, Form
W-8BEN (with respect to the benefits of any income tax treaty), Form W-8BEN
(with respect to the portfolio interest exemption) and a Section 4.04(b)(ii)
Certificate, as the case may be, and such other forms as may be required in
order to confirm or establish the entitlement of such Lender to a continued
exemption from or reduction in United States withholding tax with respect to
payments under this Agreement and any Note, or such Lender shall immediately
notify the Borrower and the Administrative Agent of its inability to deliver any
such Form or Certificate, in which case such Lender shall not be required to
deliver any such Form or Certificate pursuant to this Section 4.04(b).
Notwithstanding anything to the contrary contained in Section 4.04(a), but
subject to Section 13.04(b) and the immediately succeeding sentence, (x) the
Borrower shall be entitled, to the extent it is required to do so by



                                      -22-

law, to deduct or withhold income or similar taxes imposed by the United States
(or any political subdivision or taxing authority thereof or therein) from
interest, Fees or other amounts payable hereunder for the account of any Lender
which is not a United States person (as such term is defined in Section
7701(a)(30) of the Code) for U.S. Federal income tax purposes to the extent that
such Lender has not provided to the Borrower U.S. Internal Revenue Service forms
that establish a complete exemption from such deduction or withholding and (y)
the Borrower shall not be obligated pursuant to Section 4.04(a) hereof to
gross-up payments to be made to a Lender in respect of income or similar taxes
imposed by the United States if (I) such Lender has not provided to the Borrower
the Internal Revenue Service forms required to be provided to the Borrower
pursuant to this Section 4.04(b) or (II) in the case of a payment, other than
interest, to a Lender described in clause (ii) above, to the extent that such
forms do not establish a complete exemption from withholding of such taxes.
Notwithstanding anything to the contrary contained in the preceding sentence or
elsewhere in this Section 4.04 and except as set forth in Section 13.04(b), the
Borrower agrees to pay any additional amounts and to indemnify each Lender in
the manner set forth in Section 4.04(a) (without regard to the identity of the
jurisdiction requiring the deduction or withholding) in respect of any Taxes
deducted or withheld by it as described in the immediately preceding sentence as
a result of any changes that are effective after the Effective Date in any
applicable law, treaty, governmental rule, regulation, guideline or order, or in
the interpretation thereof, relating to the deducting or withholding of such
Taxes.

such Credit Event and also after giving effect thereto (i) there shall exist no

contained herein and in the other Credit Documents shall be true and correct in
all material respects with the same effect as though such representations and
warranties had been made on the date of such Credit Event (it being understood
and agreed that any representation or warranty which by its terms is made as of
a specified date shall be required to be true and correct in all material
respects only as of such specified date).

            6.02 Notice of Borrowing; Letter of Credit Request. (a) Prior to the
making of each Revolving Loan (other than a Revolving Loan made pursuant to a
Mandatory Borrowing), the Administrative Agent shall have received a Notice of

            The acceptance of the benefits of each Credit Event shall constitute
a representation and warranty by the Borrower to each of the Agents and each of
the Lenders that all the conditions specified in Section 5A (with respect to
Credit Events to occur on the Effective Date), in Section 5B (with respect to
Credit Events to occur on the DPRC Acquisition Date), and in this Section 6
(with respect to Credit Events to occur on or after the Effective Date) and

                                      -27-
<PAGE>   33

account of each of the Lenders and, except for the Notes, in sufficient
counterparts or copies for each of the Lenders and shall be in form and
substance satisfactory to the Agents and the Required Lenders.

            SECTION 7. Representations, Warranties and Agreements. In order to
induce the Lenders to enter into this Agreement and to make the Loans, and issue
(or participate in) the Letters of Credit as provided herein, the Borrower makes
the following representations, warranties and agreements, in each case after
giving effect to the Effective Date, all of which shall survive the execution
and delivery of this Agreement and the Notes and the making of the Loans and
issuance of the Letters of Credit, with the occurrence of each Credit Event on
or after the Effective Date being deemed to constitute a representation and
warranty that the matters specified in this Section 7 are true and correct in
all material respects on and as of the date of each such Credit Event (it being
understood and agreed that any representation or warranty which by its terms is
made as of a specified date shall be required to be true and correct in all
material respects only as of such specified date).

            7.01 Organizational Status. Each of the Borrower and each of its
Subsidiaries (i) is a duly organized and validly existing corporation,
partnership or limited liability company, as the case may be, in good standing
under the laws of the jurisdiction of its organization, except for failures to
be so duly organized, validly existing or in good standing which, either
individually or in the aggregate, could not reasonably be expected to have a
Material Adverse Effect, (ii) has the corporate, partnership or limited
liability company power and authority, as the case may be, to own its property
and assets and to transact the business in which it is engaged and presently
proposes to engage and (iii) is duly qualified and is authorized to do business
and is in good standing in each jurisdiction where the ownership, leasing or
operation of its property or the conduct of its business requires such
qualifications except for failures to be so qualified which, either individually
or in the aggregate, could not reasonably be expected to have a Material Adverse
Effect.

            7.02 Power and Authority. Each Credit Party has the corporate,
partnership or limited liability company power and authority, as the case may
be, to execute, deliver and perform the terms and provisions of each of the
Documents to which it is party and has taken all necessary corporate,
partnership or limited liability company action, as the case may be, to
authorize the execution, delivery and performance by it of each of such
Documents. Each Credit Party has duly executed and delivered each of the
Documents to which it is party, and each of such Documents constitutes its
legal, valid and binding obligation enforceable in accordance with its terms,
except to the extent that the enforceability thereof may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or other similar
laws generally affecting creditors' rights and by equitable principles
(regardless of whether enforcement is sought in equity or at law).

            7.03 No Violation. Neither the execution, delivery or performance by
any Credit Party of the Documents to which it is a party, nor compliance by it
with the terms and provisions thereof, (i) will contravene any provision of any
applicable law, statute, rule or regulation or any order, writ, injunction or
decree of any court or governmental instrumentality, (ii) will conflict



                                      -28-
<PAGE>   34

provisions of, or constitute a default under, or result in the creation or
imposition of (or the obligation to create or impose) any Lien upon any of the
property or assets of the Borrower or any of its Subsidiaries pursuant to the
terms of any material indenture, mortgage, deed of trust, credit agreement or
loan agreement, or any other material agreement, contract or instrument, to
which the Borrower or any of its Subsidiaries is a party or by which it or any
of its property or assets is bound or to which it may be subject or (iii) will
violate any provision of the certificate or articles of incorporation or by-laws
(or equivalent organizational documents) of the Borrower or any of its
Subsidiaries.

            7.04 Approvals. No order, consent, approval, license, authorization
or validation of, or filing, recording or registration with (except for (x)
those that have otherwise been obtained or made on or prior to the Effective
Date and which remain in full force and effect on the Effective Date and (y) the
receipt of the DPRC shareholder consent to approve the DPRC Merger and the
filing of the merger certificate to effect the DPRC Merger, each of which will
have been obtained or made by the time of the consummation of the DPRC Merger),
or exemption by, any governmental or public body or authority, or any
subdivision thereof, is required by any Credit Party to authorize, or is
required in connection with, (i) the execution, delivery and performance of any
Document by any Credit Party or (ii) the legality, validity, binding effect or
enforceability of any such Document against any Credit Party.

            7.05 Financial Statements; Financial Condition; Undisclosed
Liabilities; Projections; etc. (a) (i) The audited consolidated balance sheet of
the Borrower and its Subsidiaries for its fiscal year ended on March 31, 1999,
and the related audited consolidated statements of income, cash flows and
shareholders' equity of the Borrower and its Subsidiaries for the fiscal year
ended on such date, copies of which have been furnished to the Agents prior to
the Effective Date, present fairly in all material respects the consolidated
financial position of the Borrower and its Subsidiaries at the date of such
balance sheet and the consolidated results of the operations of the Borrower and
its subsidiaries for the period covered thereby. All of the foregoing financial
statements have been prepared in accordance with generally accepted accounting
principles consistently applied.

            (ii) The pro forma consolidated balance sheet of the Borrower and
its Subsidiaries as of March 31, 1999 (after giving effect to the DPRC
Acquisition and the financing therefor), and the related pro forma consolidated
statements of income, cash flows and shareholders' equity of the Borrower and
its Subsidiaries for the twelve month period ended on March 31, 1999 (after
giving effect to the DPRC Acquisition and the financing therefor and assuming
that same had occurred on April 1, 1998), copies of which have been furnished to
the Agents prior to the Effective Date, present fairly in all material respects
the pro forma consolidated financial position of the Borrower and its
Subsidiaries as of March 31, 1999 and the pro forma consolidated results of the
operations of the Borrower and its Subsidiaries for the period covered thereby.
All of the foregoing pro forma financial statements have been prepared on a
basis consistent with the historical financial statements of the Borrower set
forth in the clause (i) of this Section 7.05(a).



                                      -29-
<PAGE>   35

            (b) (i) The sum of the assets, at a fair valuation, of each of the
Borrower on a stand-alone basis and of the Borrower and its Subsidiaries taken
as a whole will exceed its debts, (ii) each of the Borrower on a stand-alone
basis and the Borrower and its Subsidiaries taken as a whole has not incurred
and does not intend to incur, and does not believe that it will incur, debts
beyond its ability to pay such debts as such debts mature, and (iii) each of the
Borrower on a stand alone basis and the Borrower and its Subsidiaries taken as a
whole will have sufficient capital with which to conduct its business. For
purposes of this Section 7.05(b), "debt" means any liability on a claim, and
"claim" means (i) right to payment, whether or not such a right is reduced to
judgment, liquidated, unliquidated, fixed, contingent, matured, unmatured,
disputed, undisputed, legal, equitable, secured, or unsecured or (ii) right to
an equitable remedy for breach of performance if such breach gives rise to a
payment, whether or not such right to an equitable remedy is reduced to
judgment, fixed, contingent, matured, unmatured, disputed, undisputed, secured
or unsecured. The amount of contingent liabilities at any time shall be computed
as the amount that, in the light of all the facts and circumstances existing at
such time, represents the amount that can reasonably be expected to become an
actual or matured liability.

            (c) Except as fully disclosed in the financial statements (including
the notes thereto) delivered pursuant to Section 7.05(a), there were as of the
Effective Date, no liabilities or obligations with respect to the Borrower or
any of its Subsidiaries (whether absolute, accrued, contingent or otherwise and
whether or not due) which, either individually or in aggregate, could reasonably
be expected to be material to the Borrower and its Subsidiaries taken as a
whole.

            (d) On and as of the Effective Date and the DPRC Acquisition Date,
the Projections delivered to the Agents prior to the Effective Date have been
prepared in good faith and are based on reasonable assumptions, and there are no
statements or conclusions in the Projections which are based upon or include
information known to the Borrower to be misleading in any material respect or
which fail to take into account material information known to the Borrower
regarding the matters reported therein. On the Effective Date and the DPRC
Acquisition Date, the Borrower believes that the Projections are reasonable and
attainable, it being recognized by the Lenders, however, that projections as to
future events are not to be viewed as facts and that the actual results during
the period or periods covered by the Projections may differ from the projected
results.

            (e) Since March 31, 1999, there has been no change in the business,
operations, properties, assets, liabilities or condition (financial or
otherwise) of the Borrower or any of its Subsidiaries that has had, or could
reasonably be expected to have, a Material Adverse Effect.

            7.06 Litigation. There are no actions, suits or proceedings pending
or, to the knowledge of the Borrower, threatened by or before any court, agency
or other governmental instrumentality that could reasonably be expected to,
either individually or in the aggregate, have a Material Adverse Effect.

            7.07 True and Complete Disclosure. All factual information (taken as
a whole) furnished by or on behalf of the Borrower in writing to any Agent or
any Lender for purposes of



                                      -30-
<PAGE>   36

or in connection with this Agreement, the other Documents or any transaction
contemplated herein or therein is, and all other such factual information (taken
as a whole) hereafter furnished by or on behalf of the Borrower in writing to
any Agent or any Lender will be, true and accurate in all material respects on
the date as of which such information is dated or certified and not incomplete
by omitting to state any fact necessary to make such information (taken as a
whole) not misleading in any material respect at such time in light of the
circumstances under which such information was provided (it being understood
that (i) the Projections shall not be subject to the representations and
warranties set forth in this Section 7.07 but instead are subject to the
representations and warranties set forth in Section 7.05(d) and (ii) no
representation or warranty is made by the Borrower pursuant to this Section 7.07
to the extent that any such information relates to a Person other than the
Borrower or a Subsidiary thereof and such information was prepared by a Person
other than the Borrower, a Subsidiary thereof or any financial, legal or other
advisor or agent of the Borrower or a Subsidiary thereof).

            7.08 Use of Proceeds; Margin Regulations. (a) All proceeds of the
Loans shall be used (i) to fund the DPRC Acquisition, (ii) to repurchase
outstanding DPRC Convertible Subordinated Notes from and after the DPRC
Acquisition Date, (iii) to pay the fees and expenses related to the foregoing,
(iv) to repay in full the Existing Compuware Credit Facility, (v) to repay in
full the Existing DPRC Credit Facility on the DPRC Acquisition Date and (vi) for
the working capital and general corporate purposes of the Borrower and its
Subsidiaries (including for acquisitions otherwise permitted under this
Agreement).

            (b) Neither the making of any Loan nor the use of the proceeds
thereof nor the occurrence of any other Credit Event will violate or be
inconsistent with the provisions of Regulation T, U or X. At the time of each
Credit Event and after giving effect thereto (including after giving effect to
the application of the proceeds therefrom), no more than 25% of the value of the
assets of the Borrower on a consolidated basis shall constitute Margin Stock.

            7.09 Tax Returns and Payments. Each of the Borrower and each of its
Subsidiaries has filed all federal income tax returns and all other material tax
returns, domestic and foreign, required to be filed by it and has paid all
material taxes and assessments payable by it which have become due, except for
those contested in good faith and adequately disclosed and fully provided for on
the financial statements of the Borrower and its Subsidiaries in accordance with
generally accepted accounting principles. There is no action, suit, proceeding,
investigation, audit, or claim now pending or, to the knowledge of the Borrower,
threatened by any authority regarding any taxes relating to the Borrower or any
of its Subsidiaries that, either individually or in the aggregate, could
reasonably be expected to result in a Material Adverse Effect.

            7.10 Compliance with ERISA. (a) Except as could not, either
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect: each Plan (and each related trust, insurance contract or fund)
is in substantial compliance with its terms and with all applicable laws,
including without limitation ERISA and the Code; each Plan (and each related
trust, if any) which is intended to be qualified under Section 401(a) of the
Code has received a determination letter from the Internal Revenue Service to
the effect that it meets the requirements



                                      -31-
<PAGE>   37

of Sections 401(a) and 501(a) of the Code; no Reportable Event has occurred; no
Plan which is a multiemployer plan (as defined in Section 4001(a)(3) of ERISA)
is insolvent or in reorganization; no Plan has an Unfunded Current Liability; no
Plan which is subject to Section 412 of the Code or Section 302 of ERISA has an
accumulated funding deficiency, within the meaning of such sections of the Code
or ERISA, or has applied for or received a waiver of an accumulated funding
deficiency or an extension of any amortization period, within the meaning of
Section 412 of the Code or Section 303 or 304 of ERISA; all contributions
required to be made with respect to a Plan have been made and no liability has
occurred as a result of any failure to make any such contribution in a timely
manner; neither the Borrower nor any Subsidiary of the Borrower nor any ERISA
Affiliate has incurred any liability (including any indirect, contingent or
secondary liability) to or on account of a Plan pursuant to Section 409, 502(i),
502(l), 515, 4062, 4063, 4064, 4069, 4201, 4204 or 4212 of ERISA or Section
401(a)(29), 4971 or 4975 of the Code or reasonably expects to incur any such
liability under any of the foregoing sections with respect to any Plan; no
condition exists which presents a material risk to the Borrower or any
Subsidiary of the Borrower or any ERISA Affiliate of incurring a liability to or
on account of a Plan pursuant to the foregoing provisions of ERISA and the Code;
no proceedings have been instituted to terminate or appoint a trustee to
administer any Plan which is subject to Title IV of ERISA; no action, suit,
proceeding, hearing, audit or investigation with respect to the administration,
operation or the investment of assets of any Plan (other than routine claims for
benefits) is pending or the Borrower is reasonably expected or threatened; using
actuarial assumptions and computation methods consistent with Part 1 of subtitle
E of Title IV of ERISA, the aggregate liabilities of the Borrower and its
Subsidiaries and its ERISA Affiliates to all Plans which are multiemployer plans
(as defined in Section 4001(a)(3) of ERISA) in the event of a complete
withdrawal therefrom, as of the close of the most recent fiscal year of each
such Plan, could not reasonably be expected to have a Material Adverse Effect;
each group health plan (as defined in Section 607(1) of ERISA or Section
4980B(g)(2) of the Code) which covers or has covered employees or former
employees of the Borrower, any Subsidiary of the Borrower, or any ERISA
Affiliate has at all times been operated in substantial compliance with the
provisions of Part 6 of subtitle B of Title I of ERISA and Section 4980B of the
Code and any failure to so comply would not result in a material liability; no
lien imposed under the Code or ERISA on the assets of the Borrower or any
Subsidiary of the Borrower or any ERISA Affiliate exists or is likely to arise
on account of any Plan; and the Borrower and its Subsidiaries may cease
contributions to or terminate any employee benefit plan maintained by any of
them without incurring any liability.

            (b) Except as could not either individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect: (i) each Foreign
Pension Plan has been maintained in substantial compliance with its terms and
with the requirements of any and all applicable laws, statutes, rules,
regulations and orders and has been maintained, where required, in good standing
with applicable regulatory authorities; (ii) all contributions required to be
made with respect to a Foreign Pension Plan have been timely made and no
liability has occurred as a result of any failure to make any such contribution
in a timely manner; (iii) neither the Borrower nor any of its Subsidiaries has
incurred any material obligation in connection with the termination of or
withdrawal from any Foreign Pension Plan; and (iv) the present value of the
accrued benefit liabilities (whether or not vested) under each Foreign Pension
Plan, determined as of the end of



                                      -32-
<PAGE>   38

the Borrower's most recently ended fiscal year on the basis of actuarial
assumptions, each of which is reasonable, did not exceed the current value of
the assets of such Foreign Pension Plan allocable to such benefit liabilities.

            7.11 Properties. Each of the Borrower and each of its Subsidiaries
has good and marketable title to, or a valid leasehold interest in, all of its
material properties, except for any defects that, either individually or in the
aggregate, could not reasonably be expected to have a Material Adverse Effect,
and all such property is free and clear of all Liens, other than Permitted
Liens.

            7.12 Year 2000. All Information Systems and Equipment are either
Year 2000 Compliant, or any reprogramming, remediation, or any other corrective
action, including the internal testing of all such Information Systems and
Equipment, will be completed by November 30, 1999, except to the extent that the
failure to be Year 2000 Compliant could not reasonably be expected to result in
a Default, an Event of Default or a Material Adverse Effect. Further, to the
extent that such reprogramming/remediation and testing action is required, the
cost thereof, as well as the cost of the reasonably foreseeable consequences of
failure to become Year 2000 Compliant, to the Borrower and its Subsidiaries
(including, without limitation, reprogramming errors and the failure of other
systems or equipment) will not result in a Default, an Event of Default or a
Material Adverse Effect.

            7.13 Subsidiaries. As of the Effective Date, the Borrower has no
Subsidiaries other than those Subsidiaries listed on Schedule III. Schedule III
correctly sets forth, as of the Effective Date, (i) the percentage ownership
(direct or indirect) of the Borrower in each class of capital stock or other
equity of each of its Subsidiaries and also identifies the direct owner thereof
and (ii) the jurisdiction of organization of each such Subsidiary.

            7.14 Compliance with Statutes, etc. Each of the Borrower and each of
its Subsidiaries is in compliance with all applicable statutes, regulations and
orders of, and all applicable restrictions imposed by, all governmental bodies,
domestic or foreign, in respect of the conduct of its business and the ownership
of its property (including applicable statutes, regulations, orders and
restrictions relating to environmental standards and controls), except such
noncompliances as could not, either individually or in the aggregate, reasonably
be expected to have a Material Adverse Effect.

            7.15 Investment Company Act. Neither the Borrower nor any of its
Subsidiaries is an "investment company" or a company "controlled" by an
"investment company," within the meaning of the Investment Company Act of 1940,
as amended.

            7.16 Public Utility Holding Company Act. Neither the Borrower nor
any of its Subsidiaries is a "holding company," or a "subsidiary company" of a
"holding company," or an "affiliate" of a "holding company" or of a "subsidiary
company" of a "holding company" within the meaning of the Public Utility Holding
Company Act of 1935, as amended.

            7.17 Environmental Matters. Except to the extent that any matter set
forth or described below in this Section 7.17, either individually or in the
aggregate, could not reasonably



                                      -33-
<PAGE>   39

be expected to have a Material Adverse Effect: each of the Borrower and each of
its Subsidiaries is in compliance with all applicable Environmental Laws and the
requirements of any permits issued under such Environmental Laws; and there are
no pending or, to the knowledge of the Borrower, threatened Environmental Claims
against the Borrower or any of its Subsidiaries (including any such claim
arising out of the ownership, lease or operation by the Borrower or any of its
Subsidiaries of any Real Property no longer owned, leased or operated by the
Borrower or any of its Subsidiaries) or any Real Property owned, leased or
operated by the Borrower or any of its Subsidiaries.

            7.18 Labor Relations. Neither the Borrower nor any of its
Subsidiaries is engaged in any unfair labor practice that, either individually
or in the aggregate, could reasonably be expected to have a Material Adverse
Effect. There is (i) no unfair labor practice complaint pending against the
Borrower or any of its Subsidiaries or, to the knowledge of the Borrower,
threatened against any of them, before the National Labor Relations Board, and
no grievance or arbitration proceeding arising out of or under any collective
bargaining agreement is so pending against the Borrower or any of its
Subsidiaries or, to the knowledge of the Borrower, threatened against any of
them, (ii) no strike, labor dispute, slowdown or stoppage pending against the
Borrower or any of its Subsidiaries or, to the knowledge of the Borrower,
threatened against the Borrower or any of its Subsidiaries and (iii) no union
representation question exists with respect to the employees of the Borrower or
any of its Subsidiaries, except (with respect to any matter specified in clause
(i), (ii) or (iii) above, either individually or in the aggregate) such as could
not, either individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect.

            7.19 Patents, Licenses, Franchises and Formulas. Each of the
Borrower and each of its Subsidiaries owns or has the right to use all the
patents, trademarks, permits, service marks, trade names, copyrights, licenses,
franchises, proprietary information (including but not limited to rights in
computer programs and databases) and formulas, or rights with respect to the
foregoing, and has obtained assignments of all leases and other rights of
whatever nature, necessary for the present conduct of its business, without any
known conflict with the rights of others which, or the failure to obtain which,
as the case may be, could reasonably be expected to result in a Material Adverse
Effect.

            SECTION 8. Affirmative Covenants. The Borrower hereby covenants and
agrees that on and after the Effective Date and until the Total Commitment and
all Letters of Credit have terminated and the Loans, Notes and Unpaid Drawings,
together with interest, Fees and all other Obligations incurred hereunder and
thereunder, are paid in full:

            8.01 Information Covenants. The Borrower will furnish to the
Administrative Agent (which will promptly forward same to each Lender):

Borrower's Form 10-Q as filed with the SEC for the respective quarterly
accounting period and within 50 days after the close thereof shall satisfy the
provisions of this clause (a) to the extent, but only to the extent, that such
Form 10-Q contains the information and/or certification required to be delivered

Subsidiaries, which audit was conducted in accordance with generally accepted
auditing standards, such accounting firm obtained no knowledge of any Default or

financial accounting matters or, if in the opinion of such accounting firm such

the nature thereof, and (ii) management's discussion and analysis of the
important operational and financial developments during such fiscal year (it
being understood and agreed that the delivery by the Borrower to the

<PAGE>   41

with the provisions of 9.02, 9.04, 9.05 and 9.07 through 9.09, inclusive, at the
end of such fiscal quarter or year, as the case may be.

            (d) Notice of Default or Litigation. Promptly upon, and in any event
within five Business Days after, any officer of the Borrower obtains knowledge
thereof, notice of (i) the occurrence of any event which constitutes a Default
or an Event of Default, (ii) any litigation or governmental investigation or
proceeding pending against the Borrower or any of its Subsidiaries which could

       Borrower or any of its Subsidiaries or any Real Property owned, leased or
       operated by the Borrower or any of its Subsidiaries; or

            (ii) any condition or occurrence on or arising from any Real
       Property owned, leased or operated by the Borrower or any of its
       Subsidiaries that (I) results in noncompliance by the Borrower or any of
       its Subsidiaries with any applicable Environmental Law or (II) could be

       or any of its Subsidiaries or any such Real Property;

Subsidiaries as any Agent or Lender may reasonably request.

            8.02 Books, Records and Inspections. The Borrower will, and will

which full, true and correct entries sufficient to prepare the financial
statements required to be delivered pursuant to this Agreement in conformity

activities. The Borrower will, and will cause each of its Subsidiaries to,
permit officers and designated representatives of any Agent or any Lender to
visit and inspect, under guidance of officers of the Borrower or such
Subsidiary, any of the properties of the Borrower or such Subsidiary, and to


                                      -36-

all at such reasonable times and intervals and to such reasonable extent as such
Agent or such Lender may reasonably request.

            8.03 Maintenance of Insurance. The Borrower will, and will cause

similarly situated owning similar properties in the same general areas in which
the Borrower or any of its Subsidiaries operates.

            8.04 Corporate Franchises. The Borrower will, and will cause each of
its Subsidiaries to, do or cause to be done, all things necessary to preserve
and keep in full force and effect its existence and its material rights,
franchises, licenses and patents; provided, however, that nothing in this
Section 8.04 shall prevent (i) sales of assets and other transactions by the
Borrower or any of its Subsidiaries in accordance with Section 9.03 or (ii) the
withdrawal by the Borrower or any of its Subsidiaries of its qualification as a
foreign corporation, partnership or limited liability company, as the case may
be, in any jurisdiction where such withdrawal could not, either individually or
in the aggregate, reasonably be expected to have a Material Adverse Effect.

            8.05 Compliance with Statutes, etc. The Borrower will, and will
cause each of its Subsidiaries to, comply with all applicable statutes,
regulations and orders of, and all applicable restrictions imposed by, all
governmental bodies, domestic or foreign, in respect of the conduct of its

cause each of its Subsidiaries to, comply in all respects with all Environmental
Laws applicable to the ownership or use of its Real Property now or hereafter

       which do not in the aggregate materially detract from the value of the
       Borrower's or such Subsidiary's property or assets or materially impair
       the use thereof in the operation of the business of the Borrower or such
       Subsidiary or (y) which are being contested in good faith by appropriate

       the property subject thereto described, in Schedule IV, but only to the

       encumber any additional assets or properties of the Borrower or any of
       its Subsidiaries (it being understood and agreed that the Borrower shall
       not be required to schedule Liens in existence on the Effective Date to
       the extent, but only to the extent, that such Liens are otherwise

       such Liens only serve to secure the payment of Indebtedness arising under
       such Capitalized Lease Obligation and (y) the Lien encumbering the asset
       giving rise to the Capitalized Lease Obligation does not encumber any
       other asset of the Borrower or any Subsidiary of the Borrower;

       acquired or constructed after the Effective Date and used in the ordinary

       permitted by Section 9.04(iv) and (y) in all events, the Lien encumbering
       the asset so acquired or acquired does not encumber any other asset of
       the Borrower or such Subsidiary, as the case may be;



                                      -40-

       shall not exceed $20,000,000 at any time outstanding;

       created in contemplation of or in connection with such acquisition or
       such Person becoming a Subsidiary of the Borrower, as the case may be,
       (ii) such Lien shall not apply to any other property or assets of the
       Borrower or any Subsidiary of the Borrower and (iii) such Lien shall
       secure only those obligations which it secures on the date of such
       acquisition or the date such Person becomes a Subsidiary of the Borrower,

       do not increase the outstanding principal amount thereof;

            (xv) Liens in favor of the United States or any State thereof, or

            (xvii) other Liens incidental to the conduct of the business or the
       ownership of the assets of the Borrower or any Subsidiary that (a) were
       not incurred in connection with borrowed money and (b) do not secure
       obligations in excess of $10,000,000 in the aggregate for all such Liens.

            9.02 Sale-Leaseback Transactions. The Borrower will not, and will
not permit any of its Subsidiaries to, enter into any arrangement with any

Sale-Leaseback Transactions then outstanding or to be so entered into) shall not
exceed 5% of Net Tangible Assets and (ii) the Borrower may consummate a
Sale-Leaseback Transaction of the Farmington Hills Property so long as the Total

       a merger or consolidation involving the Borrower, the Borrower is the
       surviving Person;

            (ii) any Person may merge or consolidate with any Subsidiary of the
       Borrower so long as (i) the surviving Person is, or as a result of such
       merger or consolidation becomes, a Subsidiary of the Borrower, and (ii)
       both before and immediately after giving effect to such merger or
       consolidation, no Default or Event of Default shall have occurred and be

            SECTION 12. The Administrative Agent and the Lead Arranger.

            12.01 Appointment. The Lenders hereby designate Comerica as
Administrative Agent to act as specified herein and in the other Credit
Documents. Each Lender hereby irrevocably authorizes, and each holder of any
Note by the acceptance of such Note shall be deemed irrevocably to authorize,
the Administrative Agent and the Lead Arranger to take such action on their
behalf under the provisions of this Agreement, the other Credit Documents and
any other instruments and agreements referred to herein or therein and to
exercise such powers and to perform such duties hereunder and thereunder as are
specifically delegated to or required of the Administrative Agent or the Lead
Arranger by the terms hereof and thereof and such other powers as are reasonably
incidental thereto. The Administrative Agent and the Lead Arranger may perform
any of their duties hereunder by or through its officers, directors, agents,
employees or affiliates.

            12.02 Nature of Duties. Neither the Administrative Agent nor the
Lead Arranger shall have any duties or responsibilities except those expressly
set forth in this Agreement and in the other Credit Documents. Neither the
Administrative Agent, the Lead Arranger nor any of its officers, directors,
agents, employees or affiliates shall be liable for any action taken or omitted
by them hereunder or under any other Credit Document or in connection herewith
or therewith, unless caused by its or their gross negligence or willful
misconduct (as determined by a court of competent jurisdiction in a final and
non-appealable decision). The duties of the Administrative Agent and the Lead
Arranger shall be mechanical and administrative in nature; neither the
Administrative Agent nor the Lead Arranger shall have by reason of this
Agreement or any other Credit Document a fiduciary relationship in respect of
any Lender or the holder of any Note; and nothing in this Agreement or any other
Credit Document, expressed or implied, is intended to or shall be so construed
as to impose upon the Administrative Agent or the Lead Arranger any obligations
in respect of this Agreement or any other Credit Document except as expressly
set forth herein or therein.

            12.03 Lack of Reliance on the Administrative Agent and the Lead
Arranger. Independently and without reliance upon the Administrative Agent or
the Lead Arranger, each Lender and the holder of each Note, to the extent it
deemed or deems appropriate, has made and shall continue to make (i) its own
independent investigation of the financial condition and affairs of the Borrower
and its Subsidiaries in connection with the making and the continuance of the
Loans and the taking or not taking of any action in connection herewith and (ii)
its own appraisal of the creditworthiness of the Borrower and its Subsidiaries
and, except as expressly provided in this Agreement, neither the Administrative
Agent nor the Lead Arranger shall have any duty or responsibility, either
initially or on a continuing basis, to provide any Lender or the holder of any
Note with any credit or other information with respect thereto, whether coming
into its possession before the making of the Loans or at any time or times
thereafter. Neither the Administrative Agent nor the Lead Arranger shall be
responsible to any Lender or the holder of any Note for any recitals,
statements, information, representations or warranties herein or in any
document, certificate or other writing delivered in connection herewith or for
the execution, effectiveness, genuineness, validity, enforceability, perfection,
collectability, priority or sufficiency of this Agreement or any other Credit
Document or the financial condition of the



                                      -67-
<PAGE>   73

Borrower or any of its Subsidiaries or be required to make any inquiry
concerning either the performance or observance of any of the terms, provisions
or conditions of this Agreement or any other Credit Document, or the financial
condition of the Borrower or any of its Subsidiaries or the existence or
possible existence of any Default or Event of Default.

            12.04 Certain Rights of the Agents. If any Agent shall request
instructions from the Required Lenders or all of the Lenders, as applicable,
with respect to any act or action (including failure to act) in connection with
this Agreement or any other Credit Document, such Agent shall be entitled to
refrain from such act or taking such action unless and until such Agent shall
have received instructions from the Required Lenders or all of the Lenders, as
applicable; and such Agent shall not incur liability to any Lender by reason of
so refraining. Without limiting the foregoing, no Lender nor the holder of any
Note shall have any right of action whatsoever against any Agent as a result of
such Agent acting or refraining from acting hereunder or under any other Credit
Document in accordance with the instructions of the Required Lenders or all of
the Lenders, as applicable.

            12.05 Reliance. The Administrative Agent and the Lead Arranger shall
be entitled to rely, and shall be fully protected in relying, upon any note,
writing, resolution, notice, statement, certificate, telex, teletype or
telecopier message, cablegram, radiogram, order or other document or telephone
message signed, sent or made by any Person that the Administrative Agent or the
Lead Arranger believed to be the proper Person, and, with respect to all legal
matters pertaining to this Agreement and any other Credit Document and its
duties hereunder and thereunder, upon advice of counsel selected by the
Administrative Agent or the Lead Arranger, as the case may be.

            12.06 Indemnification. To the extent the Administrative Agent or the
Lead Arranger is not reimbursed and indemnified by the Borrower or any of its
Subsidiaries, the Lenders will reimburse and indemnify the Administrative Agent
and the Lead Arranger in proportion to their respective "percentage" as used in
determining the Required Lenders (determined as if there were no Defaulting
Lenders) for and against any and all liabilities, obligations, losses, damages,
penalties, claims, actions, judgments, costs, expenses or disbursements of
whatsoever kind or nature which may be imposed on, asserted against or incurred
by the Administrative Agent or the Lead Arranger in performing its duties
hereunder or under any other Credit Document or in any way relating to or
arising out of this Agreement or any other Credit 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 Administrative Agent's or the Lead Arranger's gross
negligence or willful misconduct (as determined by a court of competent
jurisdiction in a final and non-appealable decision).

            12.07 The Administrative Agent and the Lead Arranger in their
Individual Capacity. With respect to their obligation to make Loans, or issue or
participate in Letters of Credit, under this Agreement, the Administrative Agent
and the Lead Arranger shall have the rights and powers specified herein for a
"Lender" and may exercise the same rights and powers as though it were not
performing the duties specified herein; and the term "Lenders," "Required

<PAGE>   74

Lenders," "holders of Notes" or any similar terms shall, unless the context
clearly otherwise indicates, include the Administrative Agent and the Lead
Arranger in their respective individual capacities. The Administrative Agent and
the Lead Arranger and their affiliates may accept deposits from, lend money to,
and generally engage in any kind of banking, investment banking, trust or other
business with, or provide debt financing, equity capital or other services
(including financial advisory services) to, any Credit Party or any Affiliate of
any Credit Party (or any Person engaged in a similar business with any Credit
Party or any Affiliate thereof) as if they were not performing the duties
specified herein, and may accept fees and other consideration from any Credit
Party or any Affiliate of any Credit Party for services in connection with this
Agreement and otherwise without having to account for the same to the Lenders.

            12.08 Holders. Any Agent may deem and treat the payee of any Note as
the owner thereof for all purposes hereof unless and until a written notice of
the assignment, transfer or endorsement thereof, as the case may be, shall have
been filed with the Administrative Agent. Any request, authority or consent of
any Person who, at the time of making such request or giving such authority or
consent, is the holder of any Note shall be conclusive and binding on any
subsequent holder, transferee, assignee or indorsee, as the case may be, of such
Note or of any Note or Notes issued in exchange therefor.

            12.09 Resignation by, and Removal of the Administrative Agent and
the Lead Arranger. (a) The Administrative Agent and/or the Lead Arranger may
resign from the performance of all its respective functions and duties hereunder
and/or under the other Credit Documents at any time by giving 15 Business Days'
prior written notice to the Lenders, and the Required Lenders may at any time
remove the Administrative Agent with or without cause by giving 15 Business
Days' prior written notice thereof to the Administrative Agent and the Lead
Arranger. Such resignation or removal, in the case of the Administrative Agent,
shall take effect upon the appointment of a successor Administrative Agent
pursuant to clauses (b) and (c) below or as otherwise provided below, and such
resignation, in the case of the Lead Arranger, shall take effect immediately.

            (b) Upon any such notice of resignation by, or removal of the,
Administrative Agent, the Required Lenders shall appoint a successor
Administrative Agent hereunder or thereunder who shall be a commercial bank,
trust company or other financial institution reasonably acceptable to the
Borrower, which acceptance shall not be unreasonably withheld or delayed
(provided that the Borrower's approval shall not be required if an Event of
Default then exists).

            (c) If a successor Administrative Agent shall not have been so
appointed within such 15 Business Day period, the Administrative Agent with the
consent of the Borrower (which consent shall not be unreasonably withheld or
delayed, provided that the Borrower's consent shall not be required if an Event
of Default then exists), shall then appoint a successor Administrative Agent who
shall serve as Administrative Agent hereunder or thereunder until such time, if
any, as the Required Lenders appoint a successor Administrative Agent as
provided above.

duties of the Administrative Agent hereunder and/or under any other Credit
Document until such time, if any, as the Required Lenders appoint a successor
Administrative Agent as provided above.

Loans or Commitment hereunder except as provided in Sections 1.13 and 13.04(b))
and the transferee, assignee or participant, as the case may be, shall not
constitute a "Lender" hereunder and, provided further, that no Lender shall
transfer or grant any participation under which the participant shall have
rights to approve any amendment to or waiver of this Agreement or any other
Credit Document except to the extent such amendment or waiver would (i) extend
the final scheduled maturity of any Revolving Loan, Note or Letter of Credit
(unless such Letter of Credit is not extended beyond the Final Maturity Date) in
which such participant is participating, or reduce the rate or extend the time
of payment of interest or Fees thereon (except in connection with a waiver of
applicability of any post-default increase in interest rates) or reduce the
principal amount thereof, or increase the amount of the participant's
participation over the amount thereof then in effect (it being understood that a
waiver of any Default or Event of Default or of a mandatory reduction in the
Total Commitment, shall not constitute a change in the terms of such
participation, and that an increase in the Commitment of any Lender shall be
permitted without the consent of any participant if the participant's
participation is not increased as a result thereof) or (ii) consent to the
assignment or transfer by the Borrower of any of its rights and obligations
under this Agreement. In the case of any such participation, the participant
shall not have any rights under this Agreement or any of the other Credit
Documents (the participant's rights against such Lender in respect of such
participation to be those set forth in the agreement executed by such Lender in
favor of the participant relating thereto) and all amounts payable by the
Borrower hereunder shall be determined as if such Lender had not sold such
participation.

            (b) Notwithstanding the foregoing, any Lender (or any Lender
together with one or more other Lenders) may (x) assign all or a portion of its
Commitment and related outstanding Obligations hereunder to (i) its parent
company and/or any affiliate of such Lender which is at least 50% owned by such
Lender or its parent company or to one or more Lenders or (ii) in the case of
any Lender that is a fund that invests in loans, any other fund that invests in
loans and is managed or advised by the same investment advisor of such Lender or
by an Affiliate of such investment advisor or (y) assign all, or if less than
all, a portion equal to at least $5,000,000 in the aggregate for the assigning
Lender or assigning Lenders, of such Commitment or Commitments and related
outstanding Obligations hereunder to one or more Eligible Transferees (treating
any fund that invests in loans and any other fund that invests in loans and is
managed or advised by the same investment advisor of such fund or by an
Affiliate of such investment advisor as a single Eligible Transferee), each of
which assignees shall become a party to this Agreement as a Lender by execution
of an Assignment and Assumption Agreement, provided that, (i) at such time
Schedule I shall be deemed modified to reflect the Commitments and/or


                                      -72-
<PAGE>   78

outstanding Revolving Loans, as the case may be, of such new Lender and of the
existing Lenders, (ii) upon the surrender of the relevant Revolving Note by the
assigning Lender (or, upon such assigning Lenders indemnifying the Borrower for
any lost Revolving Note pursuant to a customary indemnification agreement) a new
Revolving Note will be issued, at the Borrower's expense, to such new Lender and
to the assigning Lender upon the request of such new Lender or assigning Lender,
such new Revolving Note to be in conformity with the requirements of Section
1.05 (with appropriate modifications) to the extent needed to reflect the
revised Commitments and/or outstanding Revolving Loans, as the case may be,
(iii) the consent of the Administrative Agent and, so long as no Default or
Event of Default then exists, the consent of the Borrower, shall be required in
connection with any assignment to an Eligible Transferee pursuant to clause (y)
above (each of which consents shall not be unreasonably withheld or delayed),
(iv) the Administrative Agent shall receive at the time of each such assignment,
from the assigning or assignee Lender, the payment of a non-refundable
assignment fee of $3,500 (or $1,500 in the case of an assignment between or
among existing Lenders and/or their affiliates) and (v) no such transfer or
assignment will be effective until recorded by the Administrative Agent on the
Register pursuant to Section 13.15. To the extent of any assignment pursuant to
this Section 13.04(b), the assigning Lender shall be relieved of its obligations
hereunder with respect to its assigned Commitment and outstanding Revolving
Loans. At the time of each assignment pursuant to this Section 13.04(b) to a
Person which is not already a Lender hereunder and which is not a United States
person (as such term is defined in Section 7701(a)(30) of the Code) for Federal
income tax purposes, the respective assignee Lender shall, to the extent legally
entitled to do so, provide to the Borrower the appropriate Internal Revenue
Service Forms (and, if applicable, a Section 4.04(b)(ii) Certificate) described
in Section 4.04(b). To the extent that an assignment of all or any portion of a
Lender's Commitment and related outstanding Obligations pursuant to Section 1.13
or this Section 13.04(b) would, at the time of such assignment, result in
increased costs under Section 1.10, 2.06 or 4.04 from those being charged by the
respective assigning Lender prior to such assignment, then the Borrower shall
not be obligated to pay such increased costs (although the Borrower, in
accordance with and pursuant to the other provisions of this Agreement, shall be
obligated to pay any other increased costs of the type described above resulting
from changes after the date of the respective assignment).

            (c) Nothing in this Agreement shall prevent or prohibit (i) any
Lender from pledging its Revolving Loans and Revolving Note hereunder to a
Federal Reserve Bank in support of borrowings made by such Lender from such
Federal Reserve Bank or (ii) any Lender which is a fund from pledging all or any
portion of its Revolving Loans and Revolving Note to its trustee in support of
its obligations to its trustee. No pledge pursuant to this clause (c) shall
release the transferor Lender from any of its obligations hereunder.

            13.05 No Waiver; Remedies Cumulative. No failure or delay on the
part of any Agent, any Issuing Lender, the Swingline Lender or any Lender in
exercising any right, power or privilege hereunder or under any other Credit
Document and no course of dealing between the Borrower or any other Credit Party
and any Agent, any Issuing Lender, the Swingline Lender or any Lender shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right, power or privilege hereunder or under any other Credit Document preclude
any other or further exercise thereof or the exercise of any other right, power
or privilege hereunder or thereunder.



                                      -73-
<PAGE>   79

The rights, powers and remedies herein or in any other Credit Document expressly
provided are cumulative and not exclusive of any rights, powers or remedies
which any Agent, any Issuing Lender, the Swingline Lender or any Lender would
otherwise have. No notice to or demand on any Credit Party in any case shall
entitle any Credit Party to any other or further notice or demand in similar or
other circumstances or constitute a waiver of the rights of any Agent, any
Issuing Lender, the Swingline Lender or any Lender to any other or further
action in any circumstances without notice or demand.

            13.06 Payments Pro Rata. (a) Except as otherwise provided in this
Agreement, the Administrative Agent agrees that promptly after its receipt of
each payment from or on behalf of the Borrower in respect of any Obligations
hereunder, it shall distribute such payment to the Lenders (other than any
Lender that has consented in writing to waive its pro rata share of any such
payment) pro rata based upon their respective shares, if any, of the Obligations
with respect to which such payment was received.

            (b) Each of the Lenders agrees that, if it should receive any amount
hereunder (whether by voluntary payment, by realization upon security, by the
exercise of the right of setoff or banker's lien, by counterclaim or cross
action, by the enforcement of any right under the Credit Documents, or
otherwise), which is applicable to the payment of the principal of, or interest
on, the Revolving Loans, Unpaid Drawings, Commitment Commission or Letter of
Credit Fees, of a sum which with respect to the related sum or sums received by
other Lenders is in a greater proportion than the total of such Obligation then
owed and due to such Lender bears to the total of such Obligation then owed and
due to all of the Lenders immediately prior to such receipt, then such Lender
receiving such excess payment shall purchase for cash without recourse or
warranty from the other Lenders an interest in the Obligations of the respective
Credit Party to such Lenders in such amount as shall result in a proportional
participation by all the Lenders in such amount; provided that if all or any
portion of such excess amount is thereafter recovered from such Lender, such
purchase shall be rescinded and the purchase price restored to the extent of
such recovery, but without interest.

            (c) Notwithstanding anything to the contrary contained herein, the
provisions of the preceding Sections 13.06(a) and (b) shall be subject to the
express provisions of this Agreement which require, or permit, differing
payments to be made to Non-Defaulting Lenders as opposed to Defaulting Lenders.

            13.07 Calculations; Computations; Accounting Terms. (a) The
financial statements to be furnished to the Lenders pursuant hereto shall be
made and prepared in accordance with generally accepted accounting principles in
the United States consistently applied throughout the periods involved (except
as set forth in the notes thereto or as otherwise disclosed in writing by the
Borrower to the Lenders); provided that, except as otherwise specifically
provided herein, (x) all computations and all definitions used in determining
compliance with Sections 9.02 and 9.07 through 9.09, inclusive, shall utilize
accounting principles and policies in conformity with those used to prepare the
historical financial statements of the Borrower referred to in Section 7.05(a)
(i), and (y) all computations and all definitions used in determining



                                      -74-
<PAGE>   80


compliance with Sections 9.07 and 9.08 shall be determined on a Pro Forma Basis
to give effect to any Material Acquisition.

            (b) All computations of interest, Commitment Commission and other
Fees hereunder shall be made on the basis of a year of 360 days for the actual
number of days (including (in each case) the first day but excluding the last
day; except that in the case of Letter of Credit Fees and Facing Fees, the last
day shall be included) occurring in the period for which such interest,
Commitment Commission or other Fees are payable; provided that interest in
respect of Base Rate Loans determined by reference to the Prime Lending Rate
shall be made on the basis of a year of 365 or 366 days, as the case may be, for
the actual number of days occurring in the period for which such interest is
payable.

            13.08 GOVERNING LAW; SUBMISSION TO JURISDICTION; VENUE; WAIVER OF
JURY TRIAL. (a) THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE CONSTRUED IN
ACCORDANCE WITH AND BE GOVERNED BY THE LAW OF THE STATE OF NEW YORK. ANY LEGAL
ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT
MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES

CREDIT DOCUMENT, THE BORROWER HEREBY IRREVOCABLY ACCEPTS FOR ITSELF AND IN
RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE
AFORESAID COURTS. THE BORROWER HEREBY FURTHER IRREVOCABLY WAIVES ANY CLAIM THAT
ANY SUCH COURTS LACK PERSONAL JURISDICTION OVER IT, AND AGREES NOT TO PLEAD OR
CLAIM, IN ANY LEGAL ACTION PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY
OTHER CREDIT DOCUMENTS BROUGHT IN ANY OF THE AFOREMENTIONED COURTS, THAT SUCH
COURTS LACK PERSONAL JURISDICTION OVER IT. THE BORROWER FURTHER IRREVOCABLY
CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THE AFOREMENTIONED COURTS IN
ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR
CERTIFIED MAIL, POSTAGE PREPAID, TO IT AT ITS ADDRESS SET FORTH OPPOSITE ITS
SIGNATURE BELOW, SUCH SERVICE TO BECOME EFFECTIVE 30 DAYS AFTER SUCH MAILING.
THE BORROWER HEREBY IRREVOCABLY WAIVES ANY OBJECTION TO SUCH SERVICE OF PROCESS
AND FURTHER IRREVOCABLY WAIVES AND AGREES NOT TO PLEAD OR CLAIM IN ANY ACTION OR
PROCEEDING COMMENCED HEREUNDER OR UNDER ANY OTHER CREDIT DOCUMENT THAT SERVICE
OF PROCESS WAS IN ANY WAY INVALID OR INEFFECTIVE. NOTHING HEREIN SHALL AFFECT

ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE
PROCEED AGAINST THE BORROWER IN ANY OTHER JURISDICTION.

<PAGE>   81

            (b) THE BORROWER HEREBY IRREVOCABLY WAIVES ANY OBJECTION WHICH IT

ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING

            13.09 Counterparts. This Agreement may be executed in any number of
counterparts and by the different parties hereto on separate counterparts, each
of which when so executed and delivered shall be an original, but all of which
shall together constitute one and the same instrument. A set of counterparts
executed by all the parties hereto shall be lodged with the Borrower and the
Administrative Agent.

            13.10 Effectiveness. This Agreement shall become effective on the
date (the "Effective Date") on which (i) the Borrower, the Agents and the
Lenders shall have signed a counterpart hereof (whether the same or different
counterparts) and shall have delivered the same to the Administrative Agent at
the Notice Office or, in the case of the Lenders, shall have given to the
Administrative Agent telephonic (confirmed in writing), written or telex notice
(actually received) at such office that the same has been signed and mailed to
it, and (ii) the conditions contained in Section 5A are met to the satisfaction
of the Agents. The Administrative Agent will give the Borrower and each Lender
prompt written notice of the occurrence of the Effective Date.

            13.11 Headings Descriptive. The headings of the several sections and
subsections of this Agreement are inserted for convenience only and shall not in
any way affect the meaning or construction of any provision of this Agreement.

            13.12 Amendment or Waiver; etc. (a) Neither this Agreement nor any
other Credit Document nor any terms hereof or thereof may be changed, waived,
discharged or terminated unless such change, waiver, discharge or termination is
in writing signed by the respective Credit Parties party thereto and the
Required Lenders, provided that no such change, waiver, discharge or termination
shall, without the consent of each Lender (other than a Defaulting Lender) (with
Obligations being directly affected in the case of following clause (i)), (i)
extend the final scheduled maturity of any Loan or Note or extend the stated
expiration date of any Letter of Credit beyond the Final Maturity Date, or
reduce the rate or extend the time of payment of interest or Fees thereon, or
reduce the principal amount thereof (except in connection with a waiver of
applicability of any post-default increase in interest rates), (ii) release all
or



                                      -76-
<PAGE>   82

substantially all of the Subsidiary Guarantors under the Subsidiaries Guaranty
(except in connection with a sale of such Subsidiary Guarantor in accordance
with the terms of this Agreement), (iii) amend, modify or waive any provision of
this Section 13.12 (except for technical amendments with respect to additional
extensions of credit under this Agreement of the type which afford the
protections to such additional extensions of credit provided to the Commitments
on the Effective Date), (iv) reduce the percentage specified in the definition
of Required Lenders (it being understood that, with the consent of the Required
Lenders, additional extensions of credit pursuant to this Agreement may be
included in the determination of the Required Lenders on substantially the same
basis as the Commitments are included on the Effective Date) or (v) consent to
the assignment or transfer by the Borrower of any of its rights and obligations
under this Agreement; provided further, that no such change, waiver, discharge
or termination shall (1) increase the Commitment of any Lender over the amount
thereof then in effect without the consent of such Lender (it being understood
that waivers or modifications of conditions precedent, covenants, Defaults or
Events of Default or of a mandatory reduction in the Total Commitment shall not
constitute an increase of the Commitment of any Lender, and that an increase in
the available portion of the Commitment of any Lender shall not constitute an
increase of the Commitment of such Lender), (2) without the consent of the
respective Issuing Lender, amend, modify or waive any provision of Section 2 or
alter its rights or obligations with respect to Letters of Credit, (3) without
the consent of the Swingline Lender, alter the Swingline Lender's rights or
obligations with respect to Swingline Loans, or (4) without the consent of the
respective Agent, amend, modify or waive any provision of Section 12 or any
other provision as same relates to the rights or obligations of such Agent.

            (b) If, in connection with any proposed change, waiver, discharge or
termination to any of the provisions of this Agreement as contemplated by
clauses (i) through (v), inclusive, of the first proviso to Section 13.12(a),
the consent of the Required Lenders is obtained but the consent of one or more
of such other Lenders whose consent is required is not obtained, then the
Borrower shall have the right, so long as all non-consenting Lenders whose
individual consent is required are treated as described in either clauses (A) or
(B) below, to either (A) replace each such non-consenting Lender or Lenders with
one or more Replacement Lenders pursuant to Section 1.13 so long as at the time
of such replacement, each such Replacement Lender consents to the proposed
change, waiver, discharge or termination or (B) terminate such non-consenting
Lender's Commitment and/or repay the outstanding Revolving Loans of such Lender
and cash collateralize its applicable Percentage of the Letter of Credit
Outstandings in accordance with Sections 3.02(b) and 4.01(b), provided that,
unless the Commitment that is terminated, and Revolving Loans repaid, pursuant
to preceding clause (B) are immediately replaced in full at such time through
the addition of new Lenders or the increase of the Commitments and/or
outstanding Revolving Loans of existing Lenders (who in each case must
specifically consent thereto), then in the case of any action pursuant to
preceding clause (B) the Required Lenders (determined after giving effect to the
proposed action) shall specifically consent thereto, provided further, that in
any event the Borrower shall not have the right to replace a Lender, terminate
its Commitment or repay its Revolving Loans solely as a result of the exercise
of such Lender's rights (and the withholding of any required consent by such
Lender) pursuant to the second proviso to Section 13.12(a).



                                      -77-

            13.13 Survival. All indemnities set forth herein including, without
limitation, in Sections 1.10, 1.11, 2.06, 4.04, 12.06 and 13.01 shall survive
the execution, delivery and termination of this Agreement and the Notes and the
making and repayment of the Obligations.

            13.14 Domicile of Loans. Each Lender may transfer and carry its
Loans at, to or for the account of any office, Subsidiary or Affiliate of such
Lender. Notwithstanding anything to the contrary contained herein, to the extent
that a transfer of Loans pursuant to this Section 13.14 would, at the time of
such transfer, result in increased costs under Section 1.10, 1.11, 2.06 or 4.04
from those being charged by the respective Lender prior to such transfer, then
the Borrower shall not be obligated to pay such increased costs (although the
Borrower shall be obligated to pay any other increased costs of the type
described above resulting from changes after the date of the respective
transfer).

            13.15 Register. The Borrower hereby designates the Administrative
Agent to serve as the Borrower's Administrative Agent, solely for purposes of
this Section 13.15, to maintain a register (the "Register") on which it will
record the Commitments from time to time of each of the Lenders, the Loans made
by each of the Lenders and each repayment in respect of the principal amount of
the Loans of each Lender. Failure to make any such recordation, or any error in
such recordation, shall not affect the Borrower's obligations in respect of such
Loans. With respect to any Lender, the transfer of the Commitment of such Lender
and the rights to the principal of, and interest on, any Revolving Loan made
pursuant to such Commitment shall not be effective until such transfer is
recorded on the Register maintained by the Administrative Agent with respect to
ownership of such Commitment and Revolving Loans and prior to such recordation
all amounts owing to the transferor with respect to such Commitment and
Revolving Loans shall remain owing to the transferor. The registration of
assignment or transfer of all or part of any Commitments and Revolving Loans
shall be recorded by the Administrative Agent on the Register only upon the
acceptance by the Administrative Agent of a properly executed and delivered
Assignment and Assumption Agreement pursuant to Section 13.04(b). Coincident
with the delivery of such an Assignment and Assumption Agreement to the
Administrative Agent for acceptance and registration of assignment or transfer
of all or part of a Revolving Loan, or as soon thereafter as practicable, the
assigning or transferor Lender shall surrender the Revolving Note evidencing
such Revolving Loan, and thereupon one or more new Revolving Notes in the same
aggregate principal amount shall be issued to the assigning or transferor Lender
and/or the new Lender. The Borrower agrees to indemnify the Administrative Agent
from and against any and all losses, claims, damages and liabilities of
whatsoever nature which may be imposed on, asserted against or incurred by the
Administrative Agent in performing its duties under this Section 13.15.

            13.16 Confidentiality. (a) Subject to the provisions of clause (b)
of this Section 13.16, each Agent and each Lender agrees that it will use its
reasonable efforts not to disclose without the prior consent of the Borrower
(other than to its employees, auditors, advisors or counsel or to another Lender
if such Agent or Lender or such Agent's or Lender's holding or parent company in
its sole discretion determines that any such party should have access to such
information, provided such Persons shall be subject to the provisions of this
Section 13.16 to the same extent as such Agent or Lender) any information with
respect to the Borrower or any of its



                                      -78-
<PAGE>   84

Subsidiaries which is now or in the future furnished pursuant to this Agreement
or any other Credit Document and which is designated by the Borrower to the
Agents and Lenders in writing as confidential, provided that the Agents and the
Lenders may disclose any such information (i) as has become generally available
to the public other than by virtue of a breach of this Section 13.16(a) by the
Agents or the respective Lender, (ii) as may be required or appropriate in any
report, statement or testimony submitted to any municipal, state or Federal
regulatory body having or claiming to have jurisdiction over such Agent or
Lender or to the Federal Reserve Board or the Federal Deposit Insurance
Corporation or similar organizations (whether in the United States or elsewhere)
or their successors, (iii) as may be required or appropriate in respect to any
summons or subpoena or in connection with any litigation, (iv) in order to
comply with any law, order, regulation or ruling applicable to such Agent or
Lender, (v) to each of the Agents and (vi) to any prospective or actual
transferee or participant in connection with any contemplated transfer or
participation of any of the Revolving Notes or Commitments or any interest
therein by such Lender, provided that such prospective transferee or participant
agrees to be bound by the confidentiality provisions contained in this Section
13.16.

            (b) The Borrower hereby acknowledges and agrees that each Agent and
each Lender may share with any of its affiliates any information related to the
Borrower or any of its Subsidiaries (including, without limitation, any
nonpublic customer information regarding the creditworthiness of the Borrower
and its Subsidiaries), provided such Persons shall be subject to the provisions
of this Section 13.16 to the same extent as such Agent or Lender.

payment when due (whether at the stated maturity, by acceleration or otherwise)
of (x) the principal of, premium, if any, and interest on the Notes issued by,
and the Loans made to, the Borrower under the Credit Agreement, and all

incurred under, arising out of or in connection with the Credit Agreement and
any such other Credit Document and the due performance and compliance by the
Borrower with all of the terms, conditions and agreements contained in all such
Credit Documents (all such principal, premium, interest, liabilities,
indebtedness and obligations being herein collectively called the "Credit
Document Obligations"); and (ii) to each Other Creditor, the full and prompt
payment when due (whether at the stated maturity, by acceleration or otherwise)
of all obligations (including obligations which, but for the automatic stay
under Section 362(a) of the Bankruptcy Code, would become due), liabilities and
indebtedness owing by the Borrower under any Interest Rate Protection Agreement
and Other Hedging Agreement, whether now in existence or hereafter arising, and
the due performance and compliance by the Borrower with all of the terms,
conditions and agreements contained in the Interest Rate Protection Agreements
or Other Hedging Agreements (all such obligations, liabilities and indebtedness
being herein collectively called the "Other Obligations," and together with the
Credit Document Obligations, the "Guaranteed Obligations"). Each Guarantor
understands, agrees and confirms that the Creditors may enforce this Guaranty up
to the full amount of the Guaranteed Obligations against such Guarantor without
proceeding against any other Guarantor, the Borrower, against any security for
the Guaranteed Obligations, or under any other guaranty covering all or a
portion of the Guaranteed Obligations.

            2. Additionally, each Guarantor, jointly and severally,
unconditionally, absolutely and irrevocably, guarantees the payment of any and
all Guaranteed Obligations whether or not due or payable by the Borrower upon
the occurrence in respect of the Borrower of any of the events specified in
Section 10.05 of the Credit Agreement, and unconditionally and irrevocably,
jointly and severally, promises to pay such Guaranteed Obligations to the
Creditors, or order, on demand, in legal tender of the United States. This
Guaranty shall constitute a guaranty of payment, and not of collection.

            3. The liability of each Guarantor hereunder is primary, absolute
and unconditional and is exclusive and independent of any security for or other
guaranty of the indebtedness of the Borrower whether executed by such Guarantor,
any

                                                                       Exhibit G
                                                                          Page 3


other Guarantor, any other guarantor or by any other party, and the liability of
each Guarantor hereunder shall not be affected or impaired by any circumstance
or occurrence whatsoever, including, without limitation: (a) any direction as to
application of payment by the Borrower or by any other party, (b) any other
continuing or other guaranty, undertaking or maximum liability of a guarantor or
of any other party as to the Guaranteed Obligations, (c) any payment on or in
reduction of any such other guaranty or undertaking, (d) any dissolution,
termination or increase, decrease or change in personnel by the Borrower, (e)
any payment made to any Creditor on the indebtedness which any Creditor repays
the Borrower pursuant to court order in any bankruptcy, reorganization,
arrangement, moratorium or other debtor relief proceeding, and each Guarantor
waives any right to the deferral or modification of its obligations hereunder by
reason of any such proceeding, (f) any action or inaction by the Creditors as
contemplated in Section 6 hereof or (g) any invalidity, irregularity or
unenforceability of all or any part of the Guaranteed Obligations or of any
security therefor.

            4. The obligations of each Guarantor hereunder are independent of
the obligations of any other Guarantor, any other guarantor or the Borrower, and
a separate action or actions may be brought and prosecuted against each
Guarantor whether or not action is brought against any other Guarantor, any
other guarantor or the Borrower and whether or not any other Guarantor, any
other guarantor or the Borrower be joined in any such action or actions. Each
Guarantor waives, to the fullest extent permitted by law, the benefits of any
statute of limitations affecting its liability hereunder or the enforcement
thereof. Any payment by the Borrower or other circumstance which operates to
toll any statute of limitations as to the Borrower shall operate to toll the
statute of limitations as to each Guarantor.

            5. Each Guarantor hereby waives notice of acceptance of this
Guaranty and notice of any liability to which it may apply, and waives
promptness, diligence, presentment, demand of payment, protest, notice of
dishonor or nonpayment of any such liabilities, suit or taking of other action
by the Administrative Agent or any other Creditor against, and any other notice
to, any party liable thereon (including such Guarantor, any other Guarantor, any
other guarantor or the Borrower).

            6. Any Creditor may at any time and from time to time without the
consent of, or notice to, any Guarantor, without incurring responsibility to
such Guarantor, without impairing or releasing the obligations of such Guarantor
hereunder, upon or without any terms or conditions and in whole or in part:

            (a) change the manner, place or terms of payment of, and/or change
or extend the time of payment of, renew or alter (including increase), any of
the Guaranteed Obligations (including any increase or decrease in the rate of
interest thereon), any security therefor, or any liability incurred directly or
indirectly in respect thereof, and the guaranty herein made shall apply to the
Guaranteed Obligations as so changed, extended, renewed or altered;

            (b) take and hold security for the payment of the Guaranteed
Obligations and sell, exchange, release, surrender, impair, realize upon or
otherwise deal with in any manner and in any order any property by whomsoever at
any time pledged or mortgaged to secure, or

                                                                       Exhibit G
                                                                          Page 4


howsoever securing, the Guaranteed Obligations or any liabilities (including any
of those hereunder) incurred directly or indirectly in respect thereof or
hereof, and/or any offset thereagainst;

            (c) exercise or refrain from exercising any rights against the
Borrower, any other Credit Party, any Subsidiary thereof or otherwise act or
refrain from acting;

            (d) release or substitute any one or more endorsers, Guarantors,
other guarantors, the Borrower or other obligors;

            (e) settle or compromise any of the Guaranteed Obligations, any
security therefor or any liability (including any of those hereunder) incurred
directly or indirectly in respect thereof or hereof, and may subordinate the
payment of all or any part thereof to the payment of any liability (whether due
or not) of the Borrower to creditors of the Borrower other than the Creditors;

            (f) apply any sums by whomsoever paid or howsoever realized to any
liability or liabilities of the Borrower to the Creditors regardless of what
liabilities of the Borrower remain unpaid;

            (g) consent to or waive any breach of, or any act, omission or
default under, any of the Interest Rate Protection Agreements or Other Hedging
Agreements, the Credit Documents or any of the instruments or agreements
referred to therein, or otherwise amend, modify or supplement any of the
Interest Rate Protection Agreements or Other Hedging Agreements, the Credit
Documents or any of such other instruments or agreements;

            (h) act or fail to act in any manner referred to in this Guaranty
which may deprive such Guarantor of its right to subrogation against the
Borrower to recover full indemnity for any payments made pursuant to this
Guaranty; and/or

            (i) take any other action which would, under otherwise applicable
principles of common law, give rise to a legal or equitable discharge of such
Guarantor from its liabilities under this Guaranty.

            7. This Guaranty is a continuing one and all liabilities to which it
applies or may apply under the terms hereof shall be conclusively presumed to
have been created in reliance hereon. No failure or delay on the part of any
Creditor in exercising any right, power or privilege hereunder shall operate as
a waiver thereof, nor shall any single or partial exercise of any right, power
or privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein
expressly specified are cumulative and not exclusive of any rights or remedies
which any Creditor would otherwise have. No notice to or demand on any Guarantor
in any case shall entitle such Guarantor to any other further notice or demand
in similar or other circumstances or constitute a waiver of the rights of any
Creditor to any other or further action in any circumstances without notice or
demand. It is not necessary for any Creditor to inquire into the capacity or
powers of the Borrower or the officers, directors, partners or agents acting or
purporting to act on its behalf,


<PAGE>   112

                                                                       Exhibit G
                                                                          Page 5


and any indebtedness made or created in reliance upon the professed exercise of
such powers shall be guaranteed hereunder.

            8. Any indebtedness of the Borrower now or hereafter held by any
Guarantor is hereby subordinated to the indebtedness of the Borrower to the
Creditors, and such indebtedness of the Borrower to any Guarantor, if the
Administrative Agent, after the occurrence and during the continuance of an
Event of Default, so requests, shall be collected, enforced and received by such
Guarantor as trustee for the Creditors and be paid over to the Creditors on
account of the indebtedness of the Borrower to the Secured Creditors, but
without affecting or impairing in any manner the liability of such Guarantor
under the other provisions of this Guaranty. Without limiting the generality of
the foregoing, each Guarantor hereby agrees with the Creditors that it will not
exercise any right of subrogation which it may at any time otherwise have as a
result of this Guaranty (whether contractual, under Section 509 of the
Bankruptcy Code or otherwise) until all Guaranteed Obligations have been
irrevocably paid in full in cash.

            9. (a) Each Guarantor waives any right (except as shall be required
by applicable law and cannot be waived) to require the Creditors to: (i) proceed
against the Borrower, any other Guarantor, any other guarantor of the Guaranteed
Obligations or any other party; (ii) proceed against or exhaust any security
held from the Borrower, any other Guarantor, any other guarantor of the
Guaranteed Obligations or any other party; or (iii) pursue any other remedy in
the Creditors' power whatsoever. Each Guarantor waives any defense based on or
arising out of any defense of the Borrower, any other Guarantor, any other
guarantor of the Guaranteed Obligations or any other party other than payment in
full of the Guaranteed Obligations, including, without limitation, any defense
based on or arising out of the disability of the Borrower, any other Guarantor,
any other guarantor of the Guaranteed Obligations or any other party, or the
unenforceability of the Guaranteed Obligations or any part thereof from any
cause, or the cessation from any cause of the liability of the Borrower other
than payment in full of the Guaranteed Obligations. The Creditors may, at their
election, foreclose on any security held by the Administrative Agent or the
other Creditors by one or more judicial or nonjudicial sales, whether or not
every aspect of any such sale is commercially reasonable, or exercise any other
right or remedy the Creditors may have against the Borrower or any other party,
or any security, without affecting or impairing in any way the liability of any
Guarantor hereunder except to the extent the Guaranteed Obligations have been
paid in full in cash. Each Guarantor waives any defense arising out of any such
election by the Creditors, even though such election operates to impair or
extinguish any right of reimbursement or subrogation or other right or remedy of
such Guarantor against the Borrower or any other party or any security.

            (b) Each Guarantor waives all presentments, demands for performance,
protests and notices, including, without limitation, notices of nonperformance,
notices of protest, notices of dishonor, notices of acceptance of this Guaranty,
and notices of the existence, creation or incurring of new or additional
indebtedness. Each Guarantor assumes all responsibility for being and keeping
itself informed of the Borrower's financial condition and assets, and of all
other circumstances bearing upon the risk of nonpayment of the Guaranteed
Obligations and the nature, scope and extent of the risks which such Guarantor
assumes and incurs hereunder, and


<PAGE>   113


                                                                       Exhibit G
                                                                          Page 6


agrees that the Creditors shall have no duty to advise any Guarantor of
information known to them regarding such circumstances or risks.

            10. The Creditors agree that this Guaranty may be enforced only by
the action of the Administrative Agent (acting upon the instructions of the
Required Lenders) or, after the date on which all Credit Document Obligations
have been paid in full, by the holders of at least the majority of the
outstanding Other Obligations, and that no other Creditors shall have any right
individually to seek to enforce or to enforce this Guaranty, it being understood
and agreed that such rights and remedies may be exercised by the Administrative
Agent or, after all the Credit Document Obligations have been paid in full, by
the holders of at least a majority of the outstanding Other Obligations, as the
case may be, for the benefit of the Creditors upon the terms of this Guaranty.
The Creditors further agree that this Guaranty may not be enforced against any
director, officer, employee, partner, member or stockholder of any Guarantor
(except to the extent such partner, member or stockholder is also a Guarantor
hereunder).

            11. In order to induce the Lenders to make Loans to, and issue
Letters of Credit for the account of, the Borrower pursuant to the Credit
Agreement, and in order to induce the Other Creditors to execute, deliver and
perform the Interest Rate Protection Agreements and Other Hedging Agreements,
each Guarantor represents, warrants and covenants that:

            (a) Such Guarantor (i) is a duly organized and validly existing
corporation, partnership or limited liability company, as the case may be, in
good standing under the laws of the jurisdiction of its organization, except for
failures to be so duly organized validly existing or in good standing which,
either individually or in the aggregate, could not reasonably be expected to
have a Material Adverse Effect, (ii) has the corporate, partnership or limited
liability company, power and authority, as the case may be, to own its property
and assets and to transact the business in which it is engaged and presently
proposes to engage and (iii) is duly qualified and is authorized to do business
and is in good standing in each jurisdiction where the conduct of its business
requires such qualification except for failures to be so qualified which, either
individually or in the aggregate, could not reasonably be expected to have a
Material Adverse Effect.

            (b) Such Guarantor has the corporate, partnership or limited
liability company, power and authority, as the case may be, to execute, deliver
and perform the terms and provisions of this Guaranty and each other Document to
which it is a party and has taken all necessary corporate, partnership or
limited liability company, action, as the case may be, to authorize the
execution, delivery and performance by it of this Guaranty and each such other
Document. Such Guarantor has duly executed and delivered this Guaranty and each
other Document to which it is a party, and this Guaranty and each such other
Document constitutes the legal, valid and binding obligation of such Guarantor
enforceable in accordance with its terms, except to the extent that the
enforceability hereof or thereof may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or other similar laws generally affecting
creditors' rights and by equitable principles (regardless of whether enforcement
is sought in equity or at law).

                                                                       Exhibit G
                                                                          Page 7



            (c) Neither the execution, delivery or performance by such Guarantor
of this Guaranty or any other Document to which it is a party, nor compliance by
it with the terms and provisions hereof and thereof, will (i) contravene any
provision of any applicable law, statute, rule or regulation or any applicable
order, writ, injunction or decree of any court or governmental instrumentality,
(ii) conflict with or result in any breach of any of the terms, covenants,
conditions or provisions of, or constitute a default under, or result in the
creation or imposition of (or the obligation to create or impose) any Lien upon
any of the property or assets of such Guarantor or any of its Subsidiaries
pursuant to the terms of any material indenture, mortgage, deed of trust, loan
agreement, credit agreement, or any other material agreement, contract or
instrument to which such Guarantor or any of its Subsidiaries is a party or by
which it or any of its property or assets is bound or to which it may be subject
or (iii) violate any provision of the certificate of incorporation or by-laws
(or equivalent organizational documents) of such Guarantor or any of its
Subsidiaries.

            (d) No order, consent, approval, license, authorization or
validation of, or filing, recording or registration with (except as have been
obtained or made or as otherwise provided in Section 7.04 of the Credit
Agreement), or exemption by, any governmental or public body or authority, or
any subdivision thereof, is required to authorize, or is required for, (i) the
execution, delivery and performance of this Guaranty by such Guarantor or any
other Document to which such Guarantor is a party or (ii) the legality,
validity, binding effect or enforceability of this Guaranty or any other
Document to which such Guarantor is a party.

            (e) There are no actions, suits or proceedings pending or, to such
Guarantor's knowledge, threatened (i) with respect to this Guaranty or any other
Document to which such Guarantor is a party or (ii) with respect to such
Guarantor that, either individually or in the aggregate, could reasonably be
expected to have a Material Adverse Effect.

            12. Each Guarantor covenants and agrees that on and after the
Effective Date and until the termination of the Total Commitment and all
Interest Rate Protection Agreements and Other Hedging Agreements and until such
time as no Note or Letter of Credit remains outstanding and all Guaranteed
Obligations have been paid in full, such Guarantor will comply, and will cause
each of its Subsidiaries to comply, with all of the applicable provisions,
covenants and agreements contained in Sections 8 and 9 of the Credit Agreement,
and will take, or will refrain from taking, as the case may be, all actions that
are necessary to be taken or not taken so that it is not in violation of any
provision, covenant or agreement contained in Section 8 or 9 of the Credit
Agreement, and so that no Default or Event of Default, is caused by the actions
of such Guarantor or any of its Subsidiaries.

            13. The Guarantors hereby jointly and severally agree to pay all
reasonable out-of-pocket costs and expenses of each Creditor in connection with
the enforcement of this Guaranty and of each Agent in connection with any
amendment, waiver or consent relating hereto (including in each case, without
limitation, the reasonable fees and disbursements of counsel employed by each
Creditor).

                                                                       Exhibit G
                                                                          Page 8



            14. This Guaranty shall be binding upon each Guarantor and its
successors and assigns and shall inure to the benefit of the Creditors and their
successors and assigns.

            15. Neither this Guaranty nor any provision hereof may be changed,
waived, discharged or terminated except with the written consent of each
Guarantor directly affected thereby and with the written consent of either (x)
the Required Lenders (or to the extent required by Section 13.12 of the Credit
Agreement, with the written consent of each Lender) at all times prior to the
time on which all Credit Document Obligations have been paid in full or (y) the
holders of at least a majority of the outstanding Other Obligations at all times
after the time on which all Credit Document Obligations have been paid in full;
provided, that any change, waiver, modification or variance affecting the rights
and benefits of a single Class (as defined below) of Creditors (and not all
Creditors in a like or similar manner) shall also require the written consent of
the Requisite Creditors (as defined below) of such Class of Creditors (it being
understood that the addition or release of any Guarantor hereunder shall not
constitute a change, waiver, discharge or termination affecting any Guarantor
other than the Guarantor so added or released). For the purpose of this
Guaranty, the term "Class" shall mean each class of Creditors, i.e., whether (x)
the Lender Creditors as holders of the Credit Document Obligations or (y) the
Other Creditors as the holders of the Other Obligations. For the purpose of this
Guaranty, the term "Requisite Creditors" of any Class shall mean (x) with
respect to the Credit Document Obligations, the Required Lenders (or to the
extent required by Section 13.12 of the Credit Agreement, each Lender) and (y)
with respect to the Other Obligations, the holders of at least a majority of all
obligations outstanding from time to time under the Interest Rate Protection
Agreements and Other Hedging Agreements.

            16. Each Guarantor acknowledges that an executed (or conformed) copy
of each of the Credit Documents and Interest Rate Protection Agreements or Other
Hedging Agreements has been made available to a senior officer of such Guarantor
and such officer is familiar with the contents thereof.

            17. In addition to any rights now or hereafter granted under
applicable law (including, without limitation, Section 151 of the New York
Debtor and Creditor Law) and not by way of limitation of any such rights, upon
the occurrence and during the continuance of an Event of Default (such term to
mean and include any "Event of Default" as defined in the Credit Agreement or
any payment default under any Interest Rate Protection Agreement or Other
Hedging Agreement continuing after any applicable grace period), each Creditor
is hereby authorized, at any time or from time to time, without notice to any
Guarantor or to any other Person, any such notice being expressly waived, to set
off and to appropriate and apply any and all deposits (general or special) and
any other indebtedness at any time held or owing by such Creditor to or for the
credit or the account of such Guarantor, against and on account of the
obligations and liabilities of such Guarantor to such Creditor under this
Guaranty, irrespective of whether or not such Creditor shall have made any
demand hereunder and although said obligations, liabilities, deposits or claims,
or any of them, shall be contingent or unmatured.

            18. All notices, requests, demands or other communications pursuant
hereto shall be sent or delivered by mail, telegraph, telex, telecopy, cable or
overnight courier service and all


<PAGE>   116

                                                                       Exhibit G
                                                                          Page 9



such notices and communications shall, when mailed, telegraphed, telexed,
telecopied, or cabled or sent by overnight courier, be effective when deposited
in the mails, delivered to the telegraph company, cable company or overnight
courier, as the case may be, or sent by telex or telecopier and when mailed
shall be effective three Business Days following deposit in the mail with proper
postage, except that notices and communications to the Administrative Agent or
any Guarantor shall not be effective until received by the Administrative Agent
or such Guarantor, as the case may be. All notices and other communications
shall be in writing and addressed to such party at (i) in the case of any Lender
Creditor, as provided in the Credit Agreement, (ii) in the case of any
Guarantor, at c/o Compuware Corporation, 31440 Northwestern Highway, Farmington
Hills, Michigan 48334-2534, Attention: Eliot Stark, Telephone Number:
248-737-7557, Telecopier Number: 248-737-1822 and (iii) in the case of any Other
Creditor, at such address as such Other Creditor shall have specified in writing
to the Guarantors; or in any case at such other address as any of the Persons
listed above may hereafter notify the others in writing.

            19. If claim is ever made upon any Creditor for repayment or
recovery of any amount or amounts received in payment or on account of any of
the Guaranteed Obligations and any of the aforesaid payees repays all or part of
said amount by reason of (i) any judgment, decree or order of any court or
administrative body having jurisdiction over such payee or any of its property
or (ii) any settlement or compromise of any such claim effected by such payee
with any such claimant (including the Borrower) then and in such event each
Guarantor agrees that any such judgment, decree, order, settlement or compromise
shall be binding upon such Guarantor, notwithstanding any revocation hereof or
other instrument evidencing any liability of the Borrower, and such Guarantor
shall be and remain liable to the aforesaid payees hereunder for the amount so
repaid or recovered to the same extent as if such amount had never originally
been received by any such payee.

            20. (a) THIS GUARANTY AND THE RIGHTS AND OBLIGATIONS OF THE
CREDITORS AND OF THE UNDERSIGNED HEREUNDER SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK. Any legal action or proceeding
with respect to this Guaranty or any other Credit Document to which any
Guarantor is a party may be brought in the courts of the State of New York or of
the United States of America for the Southern District of New York in each case
that are located in the City of New York, and, by execution and delivery of this
Guaranty, each Guarantor hereby irrevocably accepts for itself and in respect of
its property, generally and unconditionally, the jurisdiction of the aforesaid
courts. Each Guarantor hereby further irrevocably waives any claim that any such
court lacks personal jurisdiction over such Guarantor, and agrees not to plead
or claim in any legal action or proceeding with respect to this Guaranty or any
other Credit Document to which such Guarantor is a party brought in any of the
aforesaid courts that any such court lacks personal jurisdiction over such
Guarantor. Each Guarantor further irrevocably consents to the service of process
out of any of the aforementioned courts in any such action or proceeding by the
mailing of copies thereof by registered or certified mail, postage prepaid, to
such Guarantor at its address set forth opposite its signature below, such
service to become effective 30 days after such mailing. Each Guarantor hereby
irrevocably waives any objection to such service of process and further
irrevocably waives and agrees not to plead or claim in any action or proceeding
commenced hereunder or under any other Credit Document to which such


<PAGE>   117

                                                                       Exhibit G
                                                                         Page 10


Guarantor is a party that such service of process was in any way invalid or
ineffective. Nothing herein shall affect the right of any of the Creditors to
serve process in any other manner permitted by law or to commence legal
proceedings or otherwise proceed against each Guarantor in any other
jurisdiction.

            (b) Each Guarantor hereby irrevocably waives (to the fullest extent
permitted by applicable law) any objection which it may now or hereafter have to
the laying of venue of any of the aforesaid actions or proceedings arising out
of or in connection with this Guaranty or any other Credit Document to which
such Guarantor is a party brought in the courts referred to in clause (a) above
and hereby further irrevocably waives and agrees not to plead or claim in any
such court that such action or proceeding brought in any such court has been
brought in an inconvenient forum.

            (c) EACH GUARANTOR AND EACH CREDITOR (BY ITS ACCEPTANCE OF THE
BENEFITS OF THIS GUARANTY) HEREBY IRREVOCABLY WAIVES ALL RIGHTS TO A TRIAL BY
JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO
THIS GUARANTY, THE OTHER CREDIT DOCUMENTS TO WHICH SUCH GUARANTOR IS A PARTY OR
THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

            21. In the event that all of the capital stock of one or more
Guarantors is sold or otherwise disposed of or liquidated in compliance with the
requirements of Section 9.03 of the Credit Agreement (or such sale or other
disposition has been approved in writing by the Required Lenders (or all Lenders
if required by Section 13.12 of the Credit Agreement)); such Guarantor shall
upon consummation of such sale or other disposition (except to the extent that
such sale or disposition is to the Borrower or another Subsidiary thereof) be
released from this Guaranty automatically and without further action and this
Guaranty shall, as to each such Guarantor or Guarantors, terminate, and have no
further force or effect (it being understood and agreed that the sale of one or
more Persons that own, directly or indirectly, all of the capital stock of any
Guarantor shall be deemed to be a sale of such Guarantor for the purposes of
this Section 21).

            22. At any time a payment in respect of the Guaranteed Obligations
is made under this Guaranty, the right of contribution of each Guarantor against
each other Guarantor shall be determined as provided in the immediately
following sentence, with the right of contribution of each Guarantor to be
revised and restated as of each date on which a payment (a "Relevant Payment")
is made on the Guaranteed Obligations under this Guaranty. At any time that a
Relevant Payment is made by a Guarantor that results in the aggregate payments
made by such Guarantor in respect of the Guaranteed Obligations to and including
the date of the Relevant Payment exceeding such Guarantor's Contribution
Percentage (as defined below) of the aggregate payments made by all Guarantors
in respect of the Guaranteed Obligations to and including the date of the
Relevant Payment (such excess, the "Aggregate Excess Amount"), each such
Guarantor shall have a right of contribution against each other Guarantor who
has made payments in respect of the Guaranteed Obligations to and including the
date of the Relevant Payment in an aggregate amount less than such other
Guarantor's Contribution Percentage of the aggregate payments made to and
including the date of the Relevant Payment by all Guarantors in

                                                                         Page 11


respect of the Guaranteed Obligations (the aggregate amount of such deficit, the
"Aggregate Deficit Amount") in an amount equal to (x) a fraction the numerator
of which is the Aggregate Excess Amount of such Guarantor and the denominator of
which is the Aggregate Excess Amount of all Guarantors multiplied by (y) the
Aggregate Deficit Amount of such other Guarantor. A Guarantor's right of
contribution pursuant to the preceding sentences shall arise at the time of each
computation, subject to adjustment to the time of each computation; provided,
that no Guarantor may take any action to enforce such right until the Guaranteed
Obligations have been irrevocably paid in full in cash, it being expressly
recognized and agreed by all parties hereto that any Guarantor's right of
contribution arising pursuant to this Section 22 against any other Guarantor
shall be expressly junior and subordinate to such other Guarantor's obligations
and liabilities in respect of the Guaranteed Obligations and any other
obligations owing under this Guaranty. As used in this Section 22: (i) each
Guarantor's "Contribution Percentage" shall mean the percentage obtained by
dividing (x) the Adjusted Net Worth (as defined below) of such Guarantor by (y)
the aggregate Adjusted Net Worth of all Guarantors; (ii) the "Adjusted Net
Worth" of each Guarantor shall mean the greater of (x) the Net Worth (as defined
below) of such Guarantor and (y) zero; and (iii) the "Net Worth" of each
Guarantor shall mean the amount by which the fair salable value of such
Guarantor's assets on the date of any Relevant Payment exceeds its existing
debts and other liabilities (including contingent liabilities, but without
giving effect to any Guaranteed Obligations arising under this Guaranty) on such
date. All parties hereto recognize and agree that, except for any right of
contribution arising pursuant to this Section 22, each Guarantor who makes any
payment in respect of the Guaranteed Obligations shall have no right of
contribution or subrogation against any other Guarantor in respect of such
payment until all of the Guaranteed Obligations have been irrevocably paid in
full in cash. Each of the Guarantors recognizes and acknowledges that the rights
to contribution arising hereunder shall constitute an asset in favor of the
party entitled to such contribution. In this connection, each Guarantor has the
right to waive its contribution right against any Guarantor to the extent that
after giving effect to such waiver such Guarantor would remain solvent, in the
determination of the Required Lenders.

            23. Each Guarantor and each Creditor (by its acceptance of the
benefits of this Guaranty) hereby confirms that it is its intention that this
Guaranty not constitute a fraudulent transfer or conveyance for purposes of the
Bankruptcy Code, the Uniform Fraudulent Conveyance Act of any similar Federal or
state law. To effectuate the foregoing intention, each Guarantor and each
Creditor (by its acceptance of the benefits of this Guaranty) hereby irrevocably
agrees that the Guaranteed Obligations guaranteed by such Guarantor shall be
limited to such amount as will, after giving effect to such maximum amount and
all other (contingent or otherwise) liabilities of such Guarantor that are
relevant under such laws, and after giving effect to any rights to contribution
pursuant to any agreement providing for an equitable contribution among such
Guarantor and other Guarantors, result in the Guaranteed Obligations of such
Guarantor in respect of such maximum amount not constituting a fraudulent
transfer or conveyance.

            24. This Guaranty may be executed in any number of counterparts and
by the different parties hereto on separate counterparts, each of which when so
executed and delivered shall be an original, but all of which shall together
constitute one and the same instrument. A set

                                                                         Page 12


of counterparts executed by all the parties hereto shall be lodged with the
Guarantors and the Administrative Agent.

            25. All payments made by any Guarantor hereunder will be made
without setoff, counterclaim or other defense and on the same basis as payments
are made by the Borrower under Sections 4.03 and 4.04 of the Credit Agreement.

            26. It is understood and agreed that any Subsidiary of the Borrower
that is required to execute a counterpart of this Guaranty after the date hereof
pursuant to the Credit Agreement shall become a Guarantor hereunder by executing
a counterpart hereof and delivering the same to the Administrative Agent.

                   FORM OF ASSIGNMENT AND ASSUMPTION AGREEMENT


                                                         DATE: ________ __, ____


            Reference is made to the Credit Agreement described in Item 2 of
Annex I annexed hereto (as such Credit Agreement may hereafter be amended,
modified or supplemented from time to time, the "Credit Agreement"). Unless
defined in Annex I attached hereto, capitalized terms defined in the Credit
Agreement are used herein as therein defined. _____________ (the "Assignor") and
______________ (the "Assignee") hereby agree as follows:

            1. The Assignor hereby sells and assigns to the Assignee without
recourse and without representation or warranty (other than as expressly
provided herein), and the Assignee hereby purchases and assumes from the
Assignor, that interest in and to all of the Assignor's rights and obligations
under the Credit Agreement as of the date hereof which represents the percentage
interest specified in Item 4 of Annex I (the "Assigned Share") of all of the
outstanding rights and obligations under the Credit Agreement, including,
without limitation, all rights and obligations with respect to the Assigned
Share of the Total Commitment and all outstanding Revolving Loans, Swingline
Loans and Letters of Credit.

            2. The Assignor (i) represents and warrants that it is the legal and
beneficial owner of the interest being assigned by it hereunder and that such
interest is free and clear of any adverse claims; (ii) makes no representation
or warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with the Credit Agreement
or the other Credit Documents or the execution, legality, validity,
enforceability, genuineness, sufficiency or value of the Credit Agreement or the
other Credit Documents or any other instrument or document furnished pursuant
thereto; and (iii) makes no representation or warranty and assumes no
responsibility with respect to the financial condition of the Borrower or any of
its Subsidiaries or the performance or observance by the Borrower or any of its
Subsidiaries of any of their respective obligations under the Credit Agreement
or the other Credit Documents or any other instrument or document furnished
pursuant thereto.

            3. The Assignee (i) confirms that it has received a copy of the
Credit Agreement and the other Credit Documents, together with copies of the
financial statements referred to therein and such other documents and
information as it has deemed appropriate to make its own credit analysis and
decision to enter into this Assignment and Assumption Agreement; (ii) agrees
that it will, independently and without reliance upon any Agent, the Assignor 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 the Credit Agreement; (iii) appoints and authorizes the
Administrative Agent and the Lead Arranger to take such action as agent on its
behalf and to exercise such powers under the Credit Agreement and the other
Credit Documents as are delegated to the Administrative Agent and the Lead
Arranger

                                                                          Page 2


by the terms thereof, together with such powers as are reasonably incidental
thereto, (iv) confirms that it is an Eligible Transferee under the Credit
Agreement; [and] (v) agrees that it will perform in accordance with their terms
all of the obligations which by the terms of the Credit Agreement are required
to be performed by it as a Lender [; and (vi) attaches the Forms and/or
Certificate described in Section 13.04(b) of the Credit Agreement.](1)

            4. Following the execution of this Assignment and Assumption
Agreement by the Assignor and the Assignee, an executed original hereof
(together with all attachments) will be delivered to the Administrative Agent.
The effective date of this Assignment and Assumption Agreement shall be the date
of execution hereof by the Assignor and the Assignee, the receipt of the consent
of the Administrative Agent and the Borrower (in either case) to the extent
required by the Credit Agreement, receipt by the Administrative Agent of the
assignment fee referred to in Section 13.04(b) of the Credit Agreement, and the
recordation by the Administrative Agent of the assignment effected hereby in the
Register, unless otherwise specified in Item 5 of Annex I (the "Settlement
Date").

            5. Upon the delivery of a fully executed original hereof to the
Administrative Agent, as of the Settlement Date, (i) the Assignee shall be a
party to the Credit Agreement and, to the extent provided in this Assignment and
Assumption Agreement, have the rights and obligations of a Lender thereunder and
under the other Credit Documents and (ii) the Assignor shall, to the extent
provided in this Assignment and Assumption Agreement, relinquish its rights and
be released from its obligations under the Credit Agreement and the other Credit
Documents.

            6. It is agreed that upon the effectiveness hereof, the Assignee
shall be entitled to (w) all interest on the Assigned Share of the Loans at the
rates specified in Item 6 of Annex I hereto, (x) all Commitment Commission on
the Assigned Share of the Total Commitment at the rate specified in Item 7 of
Annex I hereto and (y) all Letter of Credit Fees on the Assignee's participation
in all Letters of Credit at the rate specified in Item 8 of Annex I hereto,
which, in each case, accrue on and after the Settlement Date, such interest,
Commitment Commission and Letter of Credit Fees, to be paid by the
Administrative Agent directly to the Assignee. It is further agreed that all
payments of principal made on the Assigned Share of the Loans which occur on and
after the Settlement Date will be paid directly by the Administrative Agent to
the Assignee. Upon the Settlement Date, the Assignee shall pay to the Assignor
an amount specified by the Assignor in writing which represents the Assigned
Share of the principal amount of the respective Loans made by the Assignor
pursuant to the Credit Agreement which are outstanding on the Settlement Date,
net of any closing costs, and which are being assigned hereunder. The Assignor
and the Assignee shall make all appropriate adjustments in payments under the
Credit Agreement for periods prior to the Settlement Date directly between
themselves.
