          (d)  The entries made in the Register maintained pursuant to paragraph
               (c) of this Section 2.2 shall, absent manifest error, to the
               extent permitted by applicable law, be prima facie evidence of
               the existence and amounts of the obligations of Borrower therein
               recorded; provided, however, that the failure of any Revolving
               Credit Lender or the Agent to maintain the Register or any
               account, as applicable, or any error therein, shall not in any
               manner affect the obligation of Borrower to repay the Revolving
               Credit Advances (and all other amounts owing with respect
               thereto) made to Borrower by the Revolving Credit Lenders in
               accordance with the terms of this Agreement.

          (e)  Borrower agrees that, upon written request to the Agent by any

               Revolving Credit Note evidencing the outstanding Revolving Credit
               Advances owing to such Revolving Credit Lender.

     2.3 Requests for and Refundings and Conversions of Advances. Borrower may
request an Advance of the Revolving Credit, a refund of any Revolving Credit
Advance in the same type of Advance or to convert any Revolving Credit Advance
to any other type of Revolving Credit Advance only by delivery to Agent of a

                    refunding or conversion of an outstanding Revolving Credit
                    Advance; and

               (iii) whether such Revolving Credit Advance is to be a
                    Prime-based Advance or a Eurodollar-based Advance, and,
                    except in the case of a Prime-based Advance, the first
                    Eurodollar-Interest Period applicable thereto.

          (b)  each such Request for Revolving Credit Advance shall be delivered
               to Agent by 12:00 p.m. (Detroit time) three (3) Business Days
               prior to the proposed date of the Revolving Credit Advance,
               except in the case of a Prime-based Advance, for which the

               available under the Revolving Credit Aggregate Commitment if less
               than $2,500,000;

          (e)  in the case of a Eurodollar-based Advance, the principal amount

          (f)  a Request for Revolving Credit Advance, once delivered to Agent,
               shall not be revocable by Borrower and shall constitute a
               certification by Borrower as of the date thereof that:

               (i)  all conditions to the making of Revolving Credit Advances
                    set forth in this Agreement have been satisfied and shall
                    remain satisfied to the date of such Revolving Credit
                    Advance (both before and immediately after giving effect to
                    such Revolving Credit Advance);

                    Advance), other than any representation or warranty that

Agent, acting on behalf of the Revolving Credit Lenders, may also, at its
option, lend under this Section 2.3 upon the telephone or email request of an
Authorized Signer of the Borrower to make such requests and, in the event Agent,
acting on behalf of the Revolving Credit Lenders, makes any such Advance upon a
telephone or email request, an Authorized Signer shall fax or deliver by
electronic file to Agent, on the same day as such telephone or email request, an
executed Request for Revolving Credit Advance. Borrower hereby authorizes Agent
to disburse Advances under this Section 2.3 pursuant to the telephone or email
instructions of any person purporting to be an Authorized Signer.
Notwithstanding the foregoing, Borrower acknowledges that Borrower shall bear
all risk of loss resulting from disbursements made upon any telephone or email
request. Each telephone or email request for an Advance from an Authorized
Signer for the Borrower shall constitute a certification of the matters set
forth in the Request for Revolving Credit Advance form as of the date of such
requested Advance.

     2.4 Disbursement of Advances.

     (a) Upon receiving any Request for Revolving Credit Advance from Borrower
under Section 2.3 hereof, Agent shall promptly notify each Revolving Credit
Lender by wire, telex or telephone (confirmed by wire, telecopy or telex) of the
amount of such Advance being requested and the date such Revolving Credit
Advance is to be made by each Revolving Credit Lender in an amount equal to its
Revolving Credit Percentage of such Advance. Unless such Revolving Credit
Lender's commitment to make Revolving Credit Advances hereunder shall have been
suspended or terminated in accordance with this Agreement, each such Revolving
Credit Lender shall make available the amount of its Revolving Credit Percentage
of each Revolving Credit Advance in immediately available funds to Agent, as
follows:

               (i)  for Prime-based Advances, at the office of Agent located at
                    One Detroit Center, Detroit, Michigan 48226, not later than
                    1:00 p.m. (Detroit time) on the date of such Advance; and

               (ii) for Eurodollar-based Advances, at the Agent's Correspondent
                    for the account of the Eurodollar Lending Office of the
                    Agent, not later than 12:00 p.m. (the time of the Agent's
                    Correspondent) on the date of such Advance.

     (b) Subject to submission of an executed Request for Revolving Credit
Advance by Borrower without exceptions noted in the compliance certification
therein, Agent shall make available to Borrower the aggregate of the amounts so
received by it from the Revolving Credit Lenders in like funds and currencies:

               (i)  for Prime-based Advances, not later than 4:00 p.m. (Detroit
                    time) on the date of such Revolving Credit Advance, by
                    credit to an account of Borrower maintained with Agent or to
                    such other account or third party as Borrower may reasonably
                    direct in writing in compliance with Section 7.4(e),
                    provided such direction is timely given; and


                                       24

<PAGE>

               (ii) for Eurodollar-based Advances, not later than 4:00 p.m. (the
                    time of the Agent's Correspondent) on the date of such
                    Revolving Credit Advance, by credit to an account of
                    Borrower maintained with Agent's Correspondent or to such
                    other account or third party as Borrower may direct in
                    compliance with Section 7.4(e), provided such direction is
                    timely given.

     (c) Agent shall deliver the documents and papers received by it for the
account of each Revolving Credit Lender to such Revolving Credit Lender. Unless
Agent shall have been notified by any Revolving Credit Lender prior to the date
of any proposed Revolving Credit Advance that such Revolving Credit Lender does
not intend to make available to Agent such Revolving Credit Lender's Percentage
of such Advance, Agent may assume that such Revolving Credit Lender has made
such amount available to Agent on such date, as aforesaid. Agent may, but shall
not be obligated to, make available to Borrower the amount of such payment in
reliance on such assumption. If such amount is not in fact made available to
Agent by such Revolving Credit Lender, as aforesaid, Agent shall be entitled to
recover such amount on demand from such Revolving Credit Lender. If such
Revolving Credit Lender does not pay such amount forthwith upon Agent's demand
therefor and the Agent has in fact made a corresponding amount available to
Borrower, the Agent shall promptly notify Borrower and Borrower shall pay such
amount to Agent, if such notice is delivered to Borrower prior to 1:00 p.m.
(Detroit time) on a Business Day, on the day such notice is received, and
otherwise on the next Business Day, and such amount paid by Borrower shall be
applied as a prepayment of the Revolving Credit (without any corresponding
reduction in the Revolving Credit Aggregate Commitment), reimbursing Agent for
having funded said amounts on behalf of such Revolving Credit Lender. The
Borrower shall retain its claim against such Revolving Credit Lender with
respect to the amounts repaid by it to Agent and, if such Revolving Credit
Lender subsequently makes such amounts available to Agent, Agent shall promptly
make such amounts available to the Borrower as a Revolving Credit Advance. Agent
shall also be entitled to recover from such Revolving Credit Lender or Borrower,
as the case may be, but without duplication, interest on such amount in respect
of each day from the date such amount was made available by Agent to Borrower,
to the date such amount is recovered by Agent, at a rate per annum equal to:

               (i)  in the case of such Revolving Credit Lender, for the first
                    two (2) Business Days such amount remains unpaid, the
                    Federal Funds Effective Rate, and thereafter, at the rate of
                    interest then applicable to such Revolving Credit Advances;
                    and

               (ii) in the case of Borrower, the rate of interest then
                    applicable to such Advance of the Revolving Credit.

Until such Revolving Credit Lender has paid Agent such amount, such Revolving
Credit Lender shall have no interest in or rights with respect to such Advance
for any purpose whatsoever. The obligation of any Revolving Credit Lender to
make any Revolving Credit Advance hereunder shall not be affected by the failure
of any other Revolving Credit Lender to make any Advance hereunder, and no
Revolving Credit Lender shall have any liability to Borrower or any of its
Subsidiaries, the Agent, any other Revolving Credit Lender, or any other party
for another Revolving Credit Lender's failure to make any loan or Advance
hereunder.

     2.5 Swing Line Advances. (a) The Swing Line Lender may, subject to the
terms and conditions hereinafter set forth (including without limitation the
provisions of Section 2.5(c) hereof), but shall not be required to, make one or
more Advances (each such advance being a "Swing Line Advance") to the Borrower
from time to time on any Business Day during the period from the Effective Date
hereof until (but excluding) the Revolving Credit Maturity Date in an aggregate
amount not to exceed at any one time outstanding the Swing Line Maximum Amount.
Subject to the terms set forth herein, advances, repayments and readvances may
be made under the Swing Line.

          (b)  Accrual of Interest and Maturity; Evidence of Indebtedness.

               (i)  Swing Line Lender shall maintain in accordance with its
                    usual practice an account or accounts evidencing
                    indebtedness of the Borrower to Swing Line Lender resulting
                    from each Swing Line Advance from time to time, including
                    the amount and date of each Swing Line Advance, its
                    Applicable Interest Rate, its Interest Period, if any, and
                    the amount and date of any repayment made on any Swing Line
                    Advance from time to time. The entries made in such account
                    or accounts of Swing Line Lender shall be prima facie
                    evidence, absent manifest error, of the existence and
                    amounts of the obligations of the Borrower therein recorded;
                    provided, however, that the failure of Swing Line Lender to
                    maintain such account, as applicable, or any error therein,
                    shall not in any manner affect the obligation of the
                    Borrower to repay the Swing Line Advances (and all other
                    amounts owing with respect thereto) in accordance with the
                    terms of this Agreement.

               (ii) The Borrower agrees that, upon the written request of Swing
                    Line Lender, the Borrower will execute and deliver to Swing
                    Line Lender a Swing Line Note.

               (iii) Borrower unconditionally promises to pay to the Swing Line
                    Lender the then unpaid principal amount of such Swing Line
                    Advance (plus all accrued and unpaid interest) on the
                    Revolving Credit Maturity Date and on such other dates and
                    in such other amounts as may be required from time to time
                    pursuant to this Agreement. Subject to the terms and
                    conditions hereof, each Swing Line Advance shall, from time
                    to time after the date of such Advance (until paid), bear
                    interest at its Applicable Interest Rate.

          (c)  Requests for Swing Line Advances. Borrower may request a Swing
               Line Advance by the delivery to Swing Line Lender of a Request
               for Swing Line Advance executed by an Authorized Signer for the
               Borrower, subject to the following:

               (i)  each such Request for Swing Line Advance shall set forth the
                    information required on the Request for Advance, including

                    Advance, which must be a Business Day, (B) whether such
                    Swing Line Advance is to be a Prime-based Advance or a
                    Quoted Rate Advance, and (C) in the case of a Quoted Rate
                    Advance, the duration of the Interest Period applicable
                    thereto;

                    giving effect to all outstanding requests for Swing Line
                    Advances made by Borrower as of the date of determination,
                    the aggregate principal amount of all Swing Line Advances
                    outstanding on such date shall not exceed the Swing Line
                    Maximum Amount;

                    are deemed disbursed pursuant to Section 3.6(a) hereof in
                    respect of the Borrower's Reimbursement Obligations
                    hereunder), the sum of (x) the aggregate principal amount of
                    all Revolving Credit Advances and the Swing Line Advances
                    outstanding on such date plus (y) the Letter of Credit
                    Obligations on such date shall not exceed the lesser of then
                    applicable (A) Revolving Credit Aggregate Commitment;

               (iv) (A) in the case of a Swing Line Advance that is a
                    Prime-based Advance, the principal amount of the initial
                    funding of such Advance, as opposed to any refunding or
                    conversion thereof, shall be at least Two Hundred Fifty
                    Thousand Dollars ($250,000) or such lesser amount as may be
                    agreed to by the Swing Line Lender, and (B) in the case of a
                    Swing Line Advance that is a Quoted Rate Advance, the
                    principal amount of such Advance, plus any other outstanding
                    Swing Line Advances to be then combined therewith having the
                    same Interest Period, if any, shall be at least Two Hundred
                    Fifty Thousand Dollars ($250,000) or such lesser amount as
                    may be agreed to by the Swing Line Lender, and at any time
                    there shall not be in effect more than three (3) Interest

                         Parties contained in this Agreement and the other Loan
                         Documents are true and correct in all material respects
                         and shall be true and correct in all material respect
                         as of the date of the making of such Swing Line Advance
                         (both before and immediately after giving effect to
                         such Swing Line Advance), other than any representation
                         or warranty that expressly speaks only as of a
                         different date;

               (vii) At the option of the Agent, subject to revocation by Agent
                    at any time and from time to time and so long as the Agent
                    is the Swing Line Lender, Borrower may utilize the Agent's
                    "Sweep to Loan" automated system for obtaining Swing Line
                    Advances and making periodic repayments. At any time during
                    which the "Sweep to Loan" system is in effect, Swing Line
                    Advances shall be advanced to fund borrowing needs pursuant
                    to the terms of the Sweep Agreement. Each time a Swing Line
                    Advance is made using the "Sweep to Loan" system, Borrower
                    shall be deemed to have certified to the Agent and the
                    Lenders each of the matters set forth in clause (vi) of this
                    Section 2.5(b). Principal and interest on Swing Line
                    Advances requested, or deemed requested, pursuant to this
                    Section shall be paid pursuant to the terms and conditions
                    of the Sweep Agreement without any deduction, setoff or
                    counterclaim whatsoever. Unless sooner paid pursuant to the
                    provisions hereof or the provisions of the Sweep Agreement,
                    the principal amount of the Swing Loans shall be paid in
                    full, together with accrued interest thereon, on the
                    Revolving Credit Maturity Date. Agent may suspend or revoke
                    Borrower's privilege to use the "Sweep to Loan" system at
                    any time and from time to time for any reason and,
                    immediately upon any such revocation, the "Sweep to Loan"
                    system shall no longer be available to Borrower for the
                    funding of Swing Line Advances hereunder (or otherwise), and
                    the regular procedures set forth in this Section 2.5 for the
                    making of Swing Line Advances shall be deemed immediately to
                    apply. Agent may, at its option, also elect to make Swing
                    Line Advances upon Borrower's telephone requests on the
                    basis set


                                       28

                    forth in the last paragraph of Section 2.3, provided that
                    the Borrower complies with the provisions set forth in this
                    Section 2.5.

          (d)  Disbursement of Swing Line Advances. Upon receiving any executed
               Request for Swing Line Advance from the Borrower and the
               satisfaction of the conditions set forth in Section 2.5(c)
               hereof, Swing Line Lender shall make available to Borrower the
               amount so requested in Dollars not later than 4:00 p.m. (Detroit
               time) on the date of such Advance, by credit to an account of
               Borrower maintained with Agent or to such other account or third
               party as the Borrower may reasonably direct in writing in
               compliance with Section 7.4(e), provided such direction is timely
               given. Swing Line Lender shall promptly notify Agent of any Swing
               Line Advance by telephone, telex or telecopier.

          (e)  Refunding of or Participation Interest in Swing Line Advances.

               (i)  The Agent, at any time in its sole and absolute discretion,
                    may, in each case on behalf of the Borrower (which hereby
                    irrevocably directs the Agent to act on their behalf)
                    request each of the Revolving Credit Lenders (including the
                    Swing Line Lender in its capacity as a Revolving Credit
                    Lender) to make an Advance of the Revolving Credit to
                    Borrower, in an amount equal to such Revolving Credit
                    Lender's Revolving Credit Percentage of the aggregate
                    principal amount of the Swing Line Advances outstanding on
                    the date such notice is given (the "Refunded Swing Line
                    Advances"); provided however that the Swing Line Advances
                    carried at the Quoted Rate which are refunded with Revolving
                    Credit Advances at the request of the Swing Line Lender at a
                    time when no Default or Event of Default has occurred and is
                    continuing shall not be subject to Section 11.1 and no
                    losses, costs or expenses may be assessed by the Swing Line
                    Lender against the Borrower or the Revolving Credit Lenders
                    as a consequence of such refunding. The applicable Revolving
                    Credit Advances used to refund any Swing Line Advances shall
                    be Prime-based Advances. In connection with the making of
                    any such Refunded Swing Line Advances or the purchase of a
                    participation interest in Swing Line Advances under Section
                    2.5(e)(ii) hereof, the Swing Line Lender shall retain its
                    claim against Borrower for any unpaid interest or fees in
                    respect thereof accrued to the date of such refunding.
                    Unless any of the events described in Section 9.1(i) hereof
                    shall have occurred (in which event the procedures of
                    Section 2.5(e)(ii) shall apply) and regardless of whether
                    the conditions precedent set forth in this Agreement to the
                    making of a Revolving Credit Advance are then satisfied (but
                    subject to Section 2.5(e)(iii)), each Revolving Credit
                    Lender shall make the proceeds of its Revolving Credit
                    Advance available to the Agent for the benefit of the Swing
                    Line Lender at the office of the Agent specified in Section
                    2.4(a)

                    hereof prior to 11:00 a.m. Detroit time on the Business Day
                    next succeeding the date such notice is given, in
                    immediately available funds. The proceeds of such Revolving
                    Credit Advances shall be immediately applied to repay the
                    Refunded Swing Line Advances, subject to Section 11.1
                    hereof.

               (ii) If, prior to the making of an Advance of the Revolving
                    Credit pursuant to Section 2.5(e)(i) hereof, one of the
                    events described in Section 9.1(i) hereof shall have
                    occurred, each Revolving Credit Lender will, on the date
                    such Advance of the Revolving Credit was to have been made,
                    purchase from the Swing Line Lender an undivided
                    participating interest in each Swing Line Advance that was
                    to have been refunded in an amount equal to its Revolving
                    Credit Percentage of such Swing Line Advance. Each Revolving
                    Credit Lender within the time periods specified in Section
                    2.5(e)(i) hereof, as applicable, shall immediately transfer
                    to the Agent, for the benefit of the Swing Line Lender, in
                    immediately available funds, an amount equal to its
                    Revolving Credit Percentage of the aggregate principal
                    amount of all Swing Line Advances outstanding as of such
                    date. Upon receipt thereof, the Agent will deliver to such
                    Revolving Credit Lender a Swing Line Participation
                    Certificate evidencing such participation.

               (iii) Each Revolving Credit Lender's obligation to make Revolving
                    Credit Advances to refund Swing Line Advances, and to
                    purchase participation interests, in accordance with Section
                    2.5(e)(i) and (ii), respectively, shall be absolute and
                    unconditional and shall not be affected by any circumstance,
                    including, without limitation, (A) any set-off,
                    counterclaim, recoupment, defense or other right which such
                    Revolving Credit Lender may have against Swing Line Lender,
                    Borrower or any other Person for any reason whatsoever; (B)
                    the occurrence or continuance of any Default or Event of
                    Default; (C) any adverse change in the condition (financial
                    or otherwise) of Borrower or any other Person; (D) any
                    breach of this Agreement or any other Loan Document by
                    Borrower or any other Person; (E) any inability of Borrower
                    to satisfy the conditions precedent to borrowing set forth
                    in this Agreement on the date upon which such Revolving
                    Credit Advance is to be made or such participating interest
                    is to be purchased; (F) the termination of the Revolving
                    Credit Aggregate Commitment hereunder; or (G) any other
                    circumstance, happening or event whatsoever, whether or not
                    similar to any of the foregoing. If any Revolving Credit
                    Lender does not make available to the Agent the amount
                    required pursuant to Section 2.5(e)(i) or (ii) hereof, as
                    the case may be, the Agent on behalf of the Swing Line
                    Lender, shall be entitled to recover such amount on demand
                    from such Revolving Credit Lender, together with interest
                    thereon for each day from the date of non-payment


                                       30

<PAGE>

                    until such amount is paid in full (x) for the first two (2)
                    Business Days such amount remains unpaid, at the Federal
                    Funds Effective Rate and (y) thereafter, at the rate of
                    interest then applicable to such Swing Line Advances. The
                    obligation of any Revolving Credit Lender to make available
                    its pro rata portion of the amounts required pursuant to
                    Section 2.5(e)(i) or (ii) hereof shall not be affected by
                    the failure of any other Revolving Credit Lender to make
                    such amounts available, and no Revolving Credit Lender shall
                    have any liability to any Credit Party, the Agent, the Swing
                    Line Lender, or any other Revolving Credit Lender or any
                    other party for another Revolving Credit Lender's failure to
                    make available the amounts required under Section 2.5(e)(i)
                    or (ii) hereof.

               (iv) Notwithstanding the foregoing, no Revolving Credit Lender
                    shall be required to make any Revolving Credit Advance to
                    refund a Swing Line Advance or to purchase a participation
                    in a Swing Line Advance if at least two (2) Business Days
                    prior to the making of such Swing Line Advance by the Swing
                    Line Lender, the officers of the Swing Line Lender
                    immediately responsible for matters concerning this
                    Agreement shall have received written notice from Agent or
                    any Lender that Swing Line Advances should be suspended
                    based on the occurrence and continuance of a Default or
                    Event of Default and stating that such notice is a "notice
                    of default"; provided, however that the obligation of the
                    Revolving Credit Lenders to make such Revolving Credit
                    Advances (or purchase such participations) shall be
                    reinstated upon the date on which such Default or Event of
                    Default has been waived by the requisite Lenders.

     2.6 Interest Payments; Default Interest. (a) Interest on the unpaid balance
of all Prime-based Advances of the Revolving Credit and the Swing Line from time
to time outstanding shall accrue from the date of such Advance to the date
repaid, at a per annum interest rate equal to the Prime-based Rate, and shall be
payable in immediately available funds commencing on February 1, 2008, and on
the first day of each February, May, August and November thereafter. Whenever
any payment under this Section 2.6(a) shall become due on a day which is not a
Business Day, the date for payment thereof shall be extended to the next
Business Day. Interest accruing at the Prime-based Rate shall be computed on the
basis of a 360 day year and assessed for the actual number of days elapsed, and
in such computation effect shall be given to any change in the interest rate
resulting from a change in the Prime-based Rate on the date of such change in
the Prime-based Rate.

     (b) Interest on each Eurodollar-based Advance of the Revolving Credit shall
accrue at its Eurodollar-based Rate and shall be payable in immediately
available funds on the last day of the Eurodollar-Interest Period applicable
thereto (and, if any Eurodollar-Interest Period shall exceed three months, then
on the last Business Day of the third month of such Eurodollar-Interest Period,
and at three month intervals thereafter). Interest accruing at the
Eurodollar-based


                                       31

<PAGE>

Rate shall be computed on the basis of a 360 day year and assessed for the
actual number of days elapsed from the first day of the Eurodollar-Interest
Period applicable thereto to but not including the last day thereof.

     (c) Interest on each Quoted Rate Advance of the Swing Line shall accrue at
its Quoted Rate and shall be payable in immediately available funds on the last
day of the Interest Period applicable thereto. Interest accruing at the Quoted
Rate shall be computed on the basis of a 360-day year and assessed for the
actual number of days elapsed from the first day of the Interest Period
applicable thereto to, but not including, the last day thereof.

     (d) Notwithstanding anything to the contrary in the preceding sections, all
accrued and unpaid interest on any Revolving Credit Advance refunded or
converted pursuant to Section 2.3 hereof and any Swing Line Advance refunded
pursuant to Section 2.5(e) hereof, shall be due and payable in full on the date
such Advance is refunded or converted.

     (e) In the case of any Event of Default under Section 9.1(i), immediately
upon the occurrence thereof, and in the case of any other Event of Default,
immediately upon receipt by Agent of notice from the Majority Lenders, interest
shall be payable on demand on all Revolving Credit Advances and Swing Line
Advances from time to time outstanding at a per annum rate equal to the
Applicable Interest Rate in respect of each such Advance plus, in the case of
Eurodollar-based Advances and Quoted Rate Advances, two percent (2%) for the
remainder of the then existing Interest Period, if any, and at all other such
times, and for all Prime-based Advances from time to time outstanding, at a per
annum rate equal to the Prime-based Rate plus two percent (2%).

     2.7 Optional Prepayments.

     (a) (i) The Borrower may prepay all or part of the outstanding principal of
any Prime-based Advance(s) of the Revolving Credit at any time, provided that,
after giving effect to any partial prepayment, the aggregate balance of
Prime-based Advance(s) of the Revolving Credit remaining outstanding shall be at
least One Million Five Hundred Thousand Dollars ($1,500,000), and (ii) subject
to Section 2.10(c) hereof, the Borrower may prepay all or part of the
outstanding principal of any Eurodollar-based Advance of the Revolving Credit at
any time (subject to not less than five (5) Business Day's notice to Agent)
provided that, after giving effect to any partial prepayment, the unpaid portion
of such Advance which is to be refunded or converted under Section 2.3 hereof
shall be at least Five Hundred Thousand Dollars ($500,000).

     (b) (i) The Borrower may prepay all or part of the outstanding principal of
any Swing Line Advance carried at the Prime-based Rate at any time, provided
that after giving effect to any partial prepayment, the aggregate balance of
such Prime-based Swing Line Advances remaining outstanding shall be at least Two
Hundred Fifty Thousand Dollars ($250,000) and (ii) subject to Section 2.10(c)
hereof, the Borrower may prepay all or part of the outstanding principal of any
Swing Line Advance carried at the Quoted Rate at any time (subject to not less
than one (1) day's notice to the Swing Line Lender) provided that after giving
effect to any partial prepayment, the aggregate balance of such Quoted Rate
Swing Line Advances remaining outstanding shall be at least Fifty Thousand
Dollars ($50,000).


                                       32

<PAGE>

     (c) Any prepayment of a Prime-based Advance made in accordance with this
Section shall be without premium or penalty and any prepayment of any other type
of Advance shall be subject to the provisions of Section 11.1 hereof, but
otherwise without premium or penalty.

     2.8 Prime-based Advance in Absence of Election or Upon Default. If, (a) as
to any outstanding Eurodollar-based Advance of the Revolving Credit or any
outstanding Quoted Rate Advance of the Swing Line, Agent has not received
payment of all outstanding principal and accrued interest on the last day of the
Interest Period applicable thereto, or does not receive a timely Request for
Advance meeting the requirements of Section 2.3 or 2.5 hereof with respect to
the refunding or conversion of such Advance, or (b) subject to Section 2.6(e)
hereof, if on the last day of the applicable Interest Period a Default or an
Event of Default shall have occurred and be continuing, then, on the last day of
the applicable Interest Period the principal amount of any Eurodollar-based
Advance or Quoted Rate Advance, as the case may be, which has not been prepaid
shall, absent a contrary election of the Majority Lenders, be converted
automatically to a Prime-based Advance and the Agent shall thereafter promptly
notify Borrower of said action.

     2.9 Revolving Credit Facility Fee. From the Effective Date to the Revolving
Credit Maturity Date, Borrower shall pay to the Agent for distribution to the
Revolving Credit Lenders pro-rata in accordance with their respective
Percentages, a Revolving Credit Facility Fee quarterly in arrears commencing
February 1, 2008 and on the first day of each February, May, August and November
thereafter (in respect of the prior three months or any portion thereof).
Whenever any payment of the Revolving Credit Facility Fee shall be due on a day
which is not a Business Day, the date for payment thereof shall be extended to
the next Business Day. The Revolving Credit Facility Fee payable to each
Revolving Credit Lender shall be determined by multiplying the Applicable Fee
Percentage times such Revolving Credit Lender's Percentage of the Revolving
Credit Aggregate Commitment then in effect (whether used or unused). The
Revolving Credit Facility Fee shall be computed on the basis of a year of three
hundred sixty (360) days and assessed for the actual number of days elapsed.
Upon receipt of such payment, Agent shall make prompt payment to each Lender of
its share of the Revolving Credit Facility Fee based upon its respective
Percentage. It is expressly understood that the Revolving Credit Facility Fees
described in this Section are not refundable under any circumstances.

     2.10 Mandatory Repayment of Revolving Credit Advances.

     (a) If at any time and for any reason the aggregate outstanding principal
amount of Revolving Credit Advances plus Swing Line Advances, plus the
outstanding Letter of Credit Obligations, shall exceed the then applicable
Revolving Credit Aggregate Commitment, Borrower shall immediately reduce any
pending request for a Revolving Credit Advance on such day by the amount of such
excess and, to the extent any excess remains thereafter, repay any Revolving
Credit Advances and Swing Line Advances in an amount equal to the lesser of the
outstanding amount of such Advances and the amount of such remaining excess,
with such amounts to be applied between the Revolving Credit Advances and Swing
Line Advances as determined by the Agent and then, to the extent that any excess
remains after payment in full of all Revolving Credit Advances and Swing Line
Advances, to provide cash collateral in support of any Letter of Credit
Obligations in an amount equal to the lesser of the amount of such Letter of
Credit Obligations and the amount of such remaining excess, with such cash
collateral to be provided on the basis set forth in Section 9.2 hereof. Borrower
acknowledges that, in connection


                                       33

<PAGE>

with any repayment required hereunder, it shall also be responsible for the
reimbursement of any prepayment or other costs required under Section 11.1
hereof. Any payments made pursuant to this Section shall be applied first to
outstanding Prime-based Advances under the Revolving Credit, next to Swing Line
Advances carried at the Prime-based Rate and then to Eurodollar-based Advances
of the Revolving Credit, and then to Swing Line Advances carried at the Quoted
Rate.

     (b) Subject to Section 10.2 hereof, any payments made pursuant to this
Section shall be applied first to outstanding Prime-based Advances under the
Revolving Credit, next to Swing Line Advances carried at the Prime-based Rate,
next to Eurodollar-based Advances under the Revolving Credit, and then to Swing
Line Advances carried at the Quoted Rate. If any amounts remain thereafter, a
portion of such prepayment equivalent to the undrawn amount of any outstanding
Letters of Credit shall be held by Lender as cash collateral for the
Reimbursement Obligations, with any additional prepayment monies being applied
to any Fees, costs or expenses due and outstanding under this Agreement, and
with the remainder of such prepayment thereafter being returned to Borrower.

     (c) To the extent that, on the date any mandatory repayment of the
Revolving Credit Advances under this Section 2.10 or payment pursuant to the
terms of any of the Loan Documents is due, the Indebtedness under the Revolving
Credit or any other Indebtedness to be prepaid is being carried, in whole or in
part, at the Eurodollar-based Rate or the Quoted Rate and no Default or Event of
Default has occurred and is continuing, Borrower may deposit the amount of such
mandatory prepayment in a cash collateral account to be held by the Agent, for
and on behalf of the Revolving Credit Lenders, on such terms and conditions as
are reasonably acceptable to Agent and upon such deposit the obligation of
Borrower to make such mandatory prepayment shall be deemed satisfied. Subject to
the terms and conditions of said cash collateral account, sums on deposit in
said cash collateral account shall be applied (until exhausted) to reduce the
principal balance of the Revolving Credit on the last day of each
Eurodollar-Interest Period attributable to the Eurodollar-based Advances of such
Revolving Advance or each Interest Period attributable to the Quoted Rate
Advances, thereby avoiding breakage costs under Section 11.1 hereof; provided,
however, that if a Default or Event of Default shall have occurred at any time
while sums are on deposit in the cash collateral account, Agent may, in its sole
discretion, elect to apply such sums to reduce the principal balance of such
Eurodollar-based Advances prior to the last day of the applicable
Eurodollar-Interest Period, and the Borrower will be obligated to pay any
resulting breakage costs under Section 11.1.

     2.11 Optional Reduction or Termination of Revolving Credit Aggregate
Commitment. Borrower may, upon at least five (5) Business Days' prior written
notice to the Agent, permanently reduce the Revolving Credit Aggregate
Commitment in whole at any time, or in part from time to time, without premium
or penalty, provided that: (i) each partial reduction of the Revolving Credit
Aggregate Commitment shall be in an aggregate amount equal to Ten Million
Dollars ($10,000,000) or a larger integral multiple of One Hundred Thousand
Dollars ($100,000); (ii) each reduction shall be accompanied by the payment of
the Revolving Credit Facility Fee, if any, accrued and unpaid to the date of
such reduction; (iii) Borrower shall prepay in accordance with the terms hereof
the amount, if any, by which the aggregate unpaid principal amount of Revolving
Credit Advances and Swing Line Advances (including, without duplication, any
deemed Advances made under Section 3.6 hereof) outstanding hereunder, plus


                                       34

<PAGE>

the Letter of Credit Obligations, exceeds the amount of the then applicable
Revolving Credit Aggregate Commitment as so reduced, together with interest
thereon to the date of prepayment; (iv) no reduction shall reduce the Revolving
Credit Aggregate Commitment to an amount which is less than the aggregate
undrawn amount of any Letters of Credit outstanding at such time; and (v) no
such reduction shall reduce the Swing Line Maximum Amount unless Borrower so
elects, provided that the Swing Line Maximum Amount shall at no time be greater
than the Revolving Credit Aggregate Commitment; provided, however that if the
termination or reduction of the Revolving Credit Aggregate Commitment requires
the prepayment of a Eurodollar-based Advance or a Quoted Rate Advance and such
termination or reduction is made on a day other than the last Business Day of
the then current Interest Period applicable to such Eurodollar-based Advance or
such Quoted Rate Advance, then, pursuant to Section 11.1, Borrower shall
compensate the Revolving Credit Lenders and/or the Swing Line Lender for any
losses or, so long as no Default or Event of Default has occurred and is
continuing, Borrower may deposit the amount of such prepayment in a collateral
account as provided in Section 2.11(c). Reductions of the Revolving Credit
Aggregate Commitment and any accompanying prepayments of Advances of the
Revolving Credit shall be distributed by Agent to each Revolving Credit Lender
in accordance with such Revolving Credit Lender's Revolving Percentage thereof,
and will not be available for reinstatement by or readvance to Borrower, and any
accompanying prepayments of Advances of the Swing Line shall be distributed by
Agent to the Swing Line Lender and will not be available for reinstatement by or
readvance to the Borrower. Any reductions of the Revolving Credit Aggregate
Commitment hereunder shall reduce each Revolving Credit Lender's portion thereof
proportionately (based on the applicable Percentages), and shall be permanent
and irrevocable. Any payments made pursuant to this Section shall be applied
first to outstanding Prime-based Advances under the Revolving Credit, next to
Swing Line Advances carried at the Prime-based Rate and then to Eurodollar-based
Advances of the Revolving Credit, and then to Swing Line Advances carried at the
Quoted Rate.

     2.12 Use of Proceeds of Advances. Advances of the Revolving Credit shall be
used to finance working capital and other lawful corporate purposes, including
stock repurchases.

     2.13 Optional Increase of Revolving Credit Aggregate Commitment. Provided
that no Default or Event of Default has occurred and is continuing, and provided
that the Borrower has not previously elected to terminate the Revolving Credit
Aggregate Commitment under Section 2.11 hereof, Borrower may request that the
Revolving Credit Aggregate Commitment be increased in an aggregate amount (for
all such Requests under this Section 2.13) not to exceed the Revolving Credit
Optional Increase, subject, in each case, to Section 11.1 hereof and to the
satisfaction concurrently with or prior to the date of each such request of the
following conditions:

     (a) Borrower shall have delivered to the Agent, on or before August 1,
2012, a written request for such increase (each such request, a "Request for
Increase"), specifying the amount of Revolving Credit Optional Increase thereby
requested and in consultation with the Agent the time in which each Lender must
respond to such request (such time not to be less than ten Business Days from
the date of delivery of such notice to Lenders); provided, however that in the
event Borrower has previously delivered a Request for Increase pursuant to this
Section 2.13, Borrower may not deliver a subsequent Request for Increase until
all the conditions to effectiveness of such first Request for Increase have been
fully satisfied hereunder (or such


                                       35

<PAGE>

Request for Increase has been withdrawn), and Borrower may not submit more than
three Requests for Increases hereunder;

     (b) Agent shall have notified each Lender of the Request for Increase and
each Lender shall have notified the Agent (or, by its silence be deemed to have
notified Agent) within the required time period whether or not it agrees to
increase its Revolving Credit Commitment Amount and, if so, in what amount (with
any Lender failing to respond within such time period being deemed to have
notified Agent that it declined to increase its Revolving Credit Commitment
Amount) it being understood that no Lender shall have any obligation, express or
implied, to increase its Revolving Credit Commitment Amount;

     (c) the Lenders agreeing to increase their Revolving Credit Commitment
Amounts and, if such Lenders' increases are not sufficient to satisfy the full
amount of the Request for Increase, additional lender(s) meeting the
requirements of Section 13.8(c) hereof and acceptable to the Borrower, Agent and
the Issuing Lender (collectively, including such existing Lenders, the "New
Lender(s)") shall have become a party to this Agreement by executing and
delivering a New Lender Addendum for a minimum amount (including for the
purposes of this Section 2.13, the existing commitment of any existing Lender)
for each such New Lender of Twenty Million Dollars ($20,000,000) and an
aggregate amount for all such New Lenders of that portion of the Revolving
Credit Optional Increase, taking into account the amount of any prior increase
in the Revolving Credit Aggregate Commitment (pursuant to this Section 2.13),
covered by the applicable Request, provided, however that each New Lender shall
remit to the Agent funds in an amount equal to its Revolving Credit Percentage
(after giving effect to this Section 2.13) of all Advances of the Revolving
Credit then outstanding, such sums to be reallocated among and paid to the
existing Lenders based upon the new Percentages as determined below;

     (d) Borrower (i) shall have paid to the Agent for distribution to the
existing Lenders, as applicable, all interest, fees (including the Revolving
Credit Facility Fee and the Letter of Credit Fees) and other amounts, if any,
accrued to the effective date of such increase and any breakage fees
attributable to the reduction (prior to the last day of the applicable Interest
Period) of any outstanding Eurocurrency-based Advances, calculated on the basis
set forth in Section 11.1 hereof as though Borrower has prepaid such Advances
and (ii) shall have paid to each New Lender a special letter of credit fee on
the Letters of Credit outstanding on the effective date of such increase,
calculated on the basis of the Letter of Credit Fees which would be applicable
to such Letters of Credit if issued on the date of such increase, for the period
from the effective date of such increase to the expiration date of such Letters
of Credit;

     (e) the Borrower shall have executed and delivered to the Agent new
Revolving Credit Notes payable to each of the New Lenders in the face amount of
each such New Lender's Percentage of the Revolving Credit Aggregate Commitment
(after giving effect to this Section 2.13) and, if applicable, renewal and
replacement Revolving Credit Notes payable to each of the existing Lenders in
the face amount of each such Lender's Percentage of the Revolving Credit
Aggregate Commitment (after giving effect to this Section 2.13), each of such
Revolving Credit Notes to be substantially in the form of Exhibit B to the
Credit Agreement, as applicable, and dated as of the effective date of such
increase (with appropriate insertions relevant to such Notes and acceptable to
the applicable Lender, including the New Lenders);


                                       36
<PAGE>

     (f) the representations and warranties made by Borrower, each Guarantor or
any other party to any of the Loan Documents (excluding the Agent and Lenders)
in this Agreement or any of the other Loan Documents, and the representations
and warranties of any of the foregoing which are contained in any certificate,
document or financial or other statement furnished at any time hereunder or
thereunder or in connection herewith or therewith shall have been true and
correct in all material respects when made and shall be true and correct in all
material respects on and as of the effective date of such increase, and no
Default or Event of Default shall have occurred and be continuing as of such
date and Borrower shall have delivered written evidence of its compliance, both
before and after the occurrence of the Revolving Credit Optional Increase, with
Section 7.9 hereof; and

     (g) such other amendments, acknowledgments, consents, documents,
instruments, any registrations, if any, shall have been executed and delivered
and/or obtained by Borrower as required by Agent or the Majority Lenders, in
their reasonable discretion.

Promptly on or after the date on which all of the conditions to such Request for
Increase set forth above have been satisfied, Agent shall notify the Borrower
and each of the Lenders of the amount of the Revolving Credit Aggregate
Commitment as increased pursuant this Section 2.13 and the date on which such
increase has become effective and shall prepare a revised Schedule 1.2 to the
Credit Agreement setting forth the applicable new Percentages of the Lenders
(including the New Lender(s)), taking into account such increase and assignments
(if any).

     2.14 Optional Extensions of Revolving Credit Maturity Date. (a) Provided
that no Default or Event of Default has occurred and is continuing, Borrower
may, by written notice to Agent and each Lender (which notice shall be
irrevocable and which shall not be deemed effective unless actually received by
Agent and each Lender) not later than August 1 but not before September 1 of
each year, request that the Lenders extend the then applicable Revolving Credit
Maturity Date to a date that is one year later than the Revolving Credit
Maturity Date then in effect (such request, a "Request").

          (b)  Each Lender shall, within 30 days of receipt of such request,
               notify the Agent in writing whether such Lender consents to the
               extension of the Revolving Credit Maturity Date, such consent to
               be in the sole discretion of such Lender. If any Lender does not
               so notify the Agent of its decision within such 30 day period,
               such Lender shall be deemed to have not consented to such request
               of the Borrower.

          (c)  The Agent shall promptly notify the Borrower whether the Lenders
               have consented to such request. If the Agent does not so notify
               the Borrower within 30 days of the Agent's receipt such Request,
               the Agent shall be deemed to have notified the Borrower that the
               Lenders have not consented to the Borrower's request.

          (d)  Each Lender which elects not to extend the Revolving Credit
               Maturity Date or fails to so notify the Agent of such consent (a
               "Non-Consenting Lender") hereby agrees that if any other Lender
               or financial institution acceptable to the Borrower and the Agent
               offers to purchase such Non-


                                       37

<PAGE>

               Consenting Lender's Percentage of the Revolving Credit Aggregate
               Commitment within ten (10) days after receipt of the related
               Request for a purchase price equal to the sum of all amounts then
               owing with respect to the outstanding Advances (and
               participations in any Swing Line Advances or any Letters of
               Credit) and all other amounts accrued for the account of such
               Non-Consenting Lender, such Non-Consenting Lender will promptly
               assign, sell and transfer all of its right, title, interest and
               obligations with respect to the foregoing to such other Lender or
               financial institution pursuant to and on the terms specified in
               the form of Assignment Agreement attached hereto. Before
               assigning to a financial institution other than a Lender pursuant
               to this clause (e), each Lender that has elected to extend the
               Revolving Credit Maturity Date (a "Consenting Lender") shall have
               the right, but not any obligation, pro rata with all other
               Consenting Lenders which elect to purchase a pro rata share of
               such non-consenting Lender's Percentage of the Revolving Credit
               Aggregate Commitment (and participations in Swing Line Advances
               and Letters of Credit) to purchase each such Non-Consenting
               Lender's Percentage thereof pursuant to this clause (e). The
               Consenting Lenders which elect to exercise their purchase options
               hereunder shall by mutual agreement determine the amount of each
               Non-Consenting Lender's Percentage of the Revolving Credit
               Aggregate Commitment being purchased by each Consenting Lender,
               provided that if there is any dispute among the Consenting
               Lenders such purchase shall be based upon a pro rata sharing of
               each Non-Consenting Lender's Percentage thereof. Only if the
               Consenting Lenders have determined not to purchase all of the
               Non-Consenting Lender's Revolving Credit Aggregate Commitment may
               financial institutions other than a Consenting Lender then
               purchase such Non-Consenting Lender's Revolving Credit Aggregate
               Commitment.

          (e)  Except as set forth in subparagraph (f) hereof, notwithstanding
               anything herein to the contrary, the Revolving Credit Maturity
               Date will not be extended unless all Lenders have consented to
               the extension or if another Lender or financial institution has
               purchased each such Non-Consenting Lender's Revolving Credit
               Aggregate Commitment pursuant to the terms of clause (d) above.

          (f)  In the event, after giving effect to any assignments to
               Consenting Lenders under Section 2.16(d) hereof or otherwise,
               Lenders holding eighty percent (80%) or more of the Percentages
               (the "Approving Percentages") have consented to an extension of
               the Revolving Credit Maturity Date hereunder, such extension
               shall become effective, notwithstanding that all of the Lenders
               have failed to approve such extension in accordance with this
               Section 2.14, so long as Borrower, within forty five (45) days,
               reduces the Revolving Credit Aggregate Commitment to an amount
               not greater than the product of the Approving Percentages times
               the Revolving Credit Aggregate Commitment then in effect and
               repays the Indebtedness then outstanding hereunder (and, if
               necessary causes any outstanding Letters of


                                       38

<PAGE>

               Credit to be terminated or discharged) to the extent such
               Indebtedness exceeds the Revolving Credit Aggregate Commitment as
               so reduced, such that the entire Indebtedness outstanding to the
               Non-Consenting Lenders shall have been paid and discharged in
               full. Reductions may be made without regard to the notice
               provisions set forth herein, but shall otherwise comply with this
               Agreement, except that any amounts repaid by the Borrower against
               the Indebtedness pursuant to this subparagraph (f) shall be first
               applied to the Indebtedness outstanding to the Non-Consenting
               Lenders still holding Indebtedness hereunder at such time, with
               any remaining amounts applied in accordance with Section 2.10
               hereof and the Percentages held by such Non-Consenting Lenders
               shall be reallocated to the Consenting Lenders (giving effect to
               any assignments, as aforesaid), pro rata, based on the
               Percentages then in effect and Agent shall distribute to the
               remaining Lenders a revised Schedule reflecting such reallocated
               Percentages.

               Agreement related thereto, together with such other documents and
               materials as may be required pursuant to the terms thereof, and

               letters of credit or on banks generally that, in any case
               described in this clause (e), would make it unlawful or unduly

               Credit Lender to take an assignment of its Revolving Credit
               Percentage of the requested Letter of Credit or letters of credit

Each Letter of Credit Agreement submitted to Issuing Lender pursuant hereto
shall constitute the certification by Borrower of the matters set forth in
Sections 3.2 (a), (b) and (c) hereof. The Agent shall be entitled to rely on
such certification without any duty of inquiry.

with or promptly following its issuance of any Letter of Credit, a true and
complete copy of each Letter of Credit. Promptly upon its receipt thereof, Agent

                    (based on the amount of each Letter of Credit) in the amount
                    of the Applicable Fee Percentage (determined with reference
                    to Schedule 1.1 to this Agreement) shall be paid to the

                    with the terms of the applicable Fee Letter.

          (b)  All payments by Borrower to the Agent for distribution to the
               Issuing Lender or the Revolving Credit Lenders under this Section
               3.4 shall be made in Dollars in immediately available funds at
               the Issuing Office or such other office of the Agent as may be
               designated from time to time by written notice to Borrower by the
               Agent. The fees described in clauses (a)(i) and (ii) above (i)
               shall be nonrefundable under all circumstances, (ii) in the case
               of fees due under clause (a)(i) above, shall be payable quarterly
               in advance and (iii) in the case of fees due under clause (a)(ii)
               above, shall be payable upon the issuance of such Letter of
               Credit and upon any amendment thereto or extension thereof. The
               fees due under clause (a)(i) above shall be determined by
               multiplying the Applicable Fee Percentage times the undrawn
               amount of the face amount of each such Letter of Credit on the
               date of determination, and shall be calculated on the basis of a
               360 day year and assessed for the actual number of days from the
               date of the issuance thereof to the stated expiration thereof.
               The parties hereto acknowledge that, unless the Issuing Lender
               otherwise agrees, any material amendment and any extension to a
               Letter of Credit issued hereunder shall be treated as a new
               Letter of Credit for the purposes of the letter of credit facing
               fee.


                                       41

          (c)  If any change in any law or regulation or in the interpretation
               thereof by any court or administrative or governmental authority
               charged with the administration thereof, adopted after the date
               hereof, shall either (i) impose, modify or cause to be deemed
               applicable any reserve, special deposit, limitation or similar
               requirement against letters of credit issued or participated in
               by, or assets held by, or deposits in or for the account of,
               Issuing Lender or any Revolving Credit Lender or (ii) impose on
               Issuing Lender or any Revolving Credit Lender any other condition
               regarding this Agreement, the Letters of Credit or any
               participations in such Letters of Credit, and the result of any
               event referred to in clause (i) or (ii) above shall be to
               increase the cost or expense to Issuing Lender or such Revolving
               Credit Lender of issuing or maintaining or participating in any
               of the Letters of Credit (which increase in cost or expense shall
               be determined by the Issuing Lender's or such Revolving Credit
               Lender's reasonable allocation of the aggregate of such cost
               increases and expenses resulting from such events), then, upon
               demand by the Issuing Lender or such Revolving Credit Lender, as
               the case may be, Borrower shall, within thirty (30) days
               following demand for payment, pay to Issuing Lender or such
               Revolving Credit Lender, as the case may be, from time to time as
               specified by the Issuing Lender or such Revolving Credit Lender,
               additional amounts which shall be sufficient to compensate the
               Issuing Lender or such Revolving Credit Lender for such increased
               cost and expense (together with interest on each such amount from
               ten days after the date such payment is due until payment in full
               thereof at the Prime-based Rate), provided that if the Issuing
               Lender or such Revolving Credit Lender could take any reasonable
               action, without cost or administrative or other burden or
               restriction to such Lender, to mitigate or eliminate such cost or
               expense, it agrees to do so within a reasonable time after
               becoming aware of the foregoing matters. Each demand for payment
               under this Section 3.4(c) shall be accompanied by a certificate
               of Issuing Lender or the applicable Revolving Credit Lender
               setting forth the amount of such increased cost or expense
               incurred by the Issuing Lender or such Revolving Credit Lender,
               as the case may be, as a result of any event mentioned in clause
               (i) or (ii) above, and in reasonable detail, the methodology for
               calculating and the calculation of such amount, which certificate
               shall be prepared in good faith and shall be conclusive evidence,
               absent manifest error, as to the amount thereof.

     3.5 Other Fees. In connection with the Letters of Credit, and in addition
to the Letter of Credit Fees, Borrower shall pay, for the sole account of the
Issuing Lender, standard documentation, administration, payment and cancellation
charges assessed by Issuing Lender or the Issuing Office, at the times, in the
amounts and on the terms set forth or to be set forth from time to time in the
standard fee schedule of the Issuing Office in effect from time to time.

     3.6 Drawings and Demands for Payment Under Letters of Credit.


                                       42

<PAGE>

     (a) If the Issuing Lender shall honor a draft or other demand for payment
presented or made under any Letter of Credit, Borrower agrees to pay to the
Issuing Lender an amount equal to the amount paid by the Issuing Lender in
respect of such draft or other demand under such Letter of Credit and all
reasonable expenses paid or incurred by the Agent relative thereto not later
than 1:00 p.m. (Detroit time), on (i) the Business Day that Borrower receive
notice of such presentment and honor, if such notice is received prior to 11:00
a.m. (Detroit time) or (ii) the Business Day immediately following the day that
Borrower received such notice, if such notice is received after 11:00 a.m.
(Detroit time). Unless Borrower shall have made such payment to the Agent for
the account of the Issuing Lender on such day, the Agent shall be deemed to have
disbursed to Borrower and to have elected to substitute for the reimbursement
obligation, with respect to the applicable Letter of Credit honored by the
Issuing Lender, a Prime-based Advance of the Revolving Credit (which Advance may
be subsequently converted at any time into a Eurodollar-based Advance pursuant
to Section 2.3 hereof) on behalf of and for the account of the Revolving Credit
Lenders in an aggregate amount equal to the amount so paid by the Issuing Lender
in respect of such draft or other demand under such Letter of Credit. Such
Prime-based Advance shall be deemed disbursed notwithstanding any failure to
satisfy any conditions for disbursement of any Advance set forth in Section 2
hereof and, to the extent of the Advances so disbursed, the reimbursement
obligation of Borrower under this Section 3.6 shall be deemed satisfied.

     (b) If the Issuing Lender shall honor a draft or other demand for payment
presented or made under any Letter of Credit, the Issuing Lender shall provide
notice thereof to Borrower on the date such draft or demand is honored, and to
each Revolving Credit Lender on such date unless Borrower shall have satisfied
its reimbursement obligations under Section 3.6(a) hereof by payment to the
Agent (for the benefit of the Issuing Lender) on such date. The Issuing Lender
shall further use reasonable efforts to provide notice to Borrower prior to
honoring any such draft or other demand for payment, but such notice, or the
failure to provide such notice, shall not affect the rights or obligations of
the Issuing Lender with respect to any Letter of Credit or the rights and
obligations of the parties hereto, including without limitation the obligations
of Borrower under Section 3.6(a) hereof.

     (c) Upon issuance by the Issuing Lender of each Letter of Credit hereunder,
each Revolving Credit Lender shall automatically acquire a pro rata
participation interest in such Letter of Credit and each related Letter of
Credit Payment based on its respective Revolving Credit Percentage. Each
Revolving Credit Lender, on the date a draft or demand under any Letter of
Credit is honored (or the next succeeding Business Day if the notice required to
be given by Issuing Lender to the Revolving Credit Lenders under Section 3.6(b)
hereof is not given to the Revolving Credit Lenders prior to 2:00 p.m. (Detroit
time) on such date of draft or demand), shall make its Revolving Credit
Percentage of the amount paid by the Issuing Lender, and not reimbursed by
Borrower on such day, in immediately available funds at the principal office of
the Agent for the account of Issuing Lender. If and to the extent such Revolving
Credit Lender shall not have made such pro rata portion available to the Agent,
such Revolving Credit Lender agrees to pay to the Agent for the account of the
Issuing Lender forthwith on demand such amount together with interest thereon,
for each day from the date such amount was paid by the Issuing Lender until such
amount is so made available to the Agent at the Federal Funds Rate for the first
three days and thereafter at a Prime-based Rate applicable during such period to
the related Advance deemed to have been disbursed under Section 3.6(a) in
respect of the


                                       43

<PAGE>

reimbursement obligation of Borrower. If such Revolving Credit Lender shall pay
such amount to the Agent for the account of Issuing Lender together with such
interest, if any, such amount so paid shall be deemed to constitute an Advance
by such Revolving Credit Lender disbursed in respect of the reimbursement
obligation of Borrower under Section 3.6(a) hereof for purposes of this
Agreement, effective as of the dates applicable under said Section 3.6(a). The
failure of any Revolving Credit Lender to make its pro rata portion of any such
amount paid by the Issuing Lender available to the Agent for the account of
Issuing Lender shall not relieve any other Revolving Credit Lender of its
obligation to make available its pro rata portion of such amount, but no
Revolving Credit Lender shall be responsible for failure of any other Revolving
Credit Lender to make such pro rata portion available to the Agent for the
account of Issuing Lender.

     Notwithstanding the foregoing however no Revolving Credit Lender shall be
deemed to have acquired a participation in a Letter of Credit if the officers of
the Issuing Lender immediately responsible for matters concerning this Agreement
shall have received written notice from Agent or any Lender at least two (2)
Business Days prior to the date of the issuance of such Letter of Credit that
the issuance of Letters of Credit should be suspended based on the occurrence
and continuance of a Default or Event of Default and stating that such notice is
a "notice of default"; provided, however that the Revolving Credit Lenders shall
be deemed to have acquired such a participation upon the date on which such
Default or Event of Default has been waived by the requisite Revolving Credit
Lenders, as applicable.

     (d) Nothing in this Agreement shall be construed to require or authorize
any Revolving Credit Lender to issue any Letter of Credit, it being recognized
that the Issuing Lender shall be the sole issuer of Letters of Credit under this
Agreement.

     3.7 Obligations Irrevocable. The obligations of Borrower to make payments
to Agent for the account of Issuing Lender or the Revolving Credit Lenders with
respect to Letter of Credit Obligations under Section 3.6 hereof, shall be
unconditional and irrevocable and not subject to any qualification or exception
whatsoever, including, without limitation:

          (a)  Any lack of validity or enforceability of any Letter of Credit,
               any Letter of Credit Agreement, any other documentation relating
               to any Letter of Credit, this Agreement or any of the other Loan
               Documents (the "Letter of Credit Documents");

          (b)  Any amendment, modification, waiver, consent, or any
               substitution, exchange or release of or failure to perfect any
               interest in collateral or security, with respect to or under any
               Letter of Credit Document;

          (c)  The existence of any claim, setoff, defense or other right which
               Borrower may have at any time against any beneficiary or any
               transferee of any Letter of Credit (or any persons or entities
               for whom any such beneficiary or any such transferee may be
               acting), the Agent, the Issuing Lender or any Revolving Credit
               Lender or any other Person, whether in connection with this
               Agreement, any of the Letter of Credit Documents, the
               transactions contemplated herein or therein or any unrelated
               transactions;


                                       44

<PAGE>

          (d)  Any draft or other statement or 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;

          (e)  Payment by the Issuing Lender to the beneficiary under any Letter
               of Credit against presentation of documents which do not comply
               with the terms of such Letter of Credit, including failure of any
               documents to bear any reference or adequate reference to such
               Letter of Credit;

          (f)  Any failure, omission, delay or lack on the part of the Agent,
               Issuing Lender or any Revolving Credit Lender or any party to any
               of the Letter of Credit Documents to enforce, assert or exercise
               any right, power or remedy conferred upon the Agent, Issuing
               Lender, any Revolving Credit Lender or any such party under this
               Agreement, any of the other Loan Documents or any of the Letter
               of Credit Documents, or any other acts or omissions on the part
               of the Agent, Issuing Lender, any Revolving Credit Lender or any
               such party; or

          (g)  Any other event or circumstance that would, in the absence of
               this Section 3.7, result in the release or discharge by operation
               of law or otherwise of Borrower from the performance or
               observance of any obligation, covenant or agreement contained in
               Section 3.6 hereof.

No setoff, counterclaim, reduction or diminution of any obligation or any
defense of any kind or nature which Borrower has or may have against the
beneficiary of any Letter of Credit shall be available hereunder to Borrower
against the Agent, Issuing Lender or any Revolving Credit Lender. With respect
to any Letter of Credit, nothing contained in this Section 3.7 shall be deemed
to prevent Borrower, after satisfaction in full of the absolute and
unconditional obligations of Borrower hereunder with respect to such Letter of
Credit, from asserting in a separate action any claim, defense, set off or other
right which they (or any of them) may have against Agent, Issuing Lender or any
Revolving Credit Lender in connection with such Letter of Credit.

     3.8 Risk Under Letters of Credit.

     (a) In the administration and handling of Letters of Credit and any
security therefor, or any documents or instruments given in connection
therewith, Issuing Lender shall have the sole right to take or refrain from
taking any and all actions under or upon the Letters of Credit.

     (b) Subject to other terms and conditions of this Agreement, Issuing Lender
shall issue the Letters of Credit and shall hold the documents related thereto
in its own name and shall make all collections thereunder and otherwise
administer the Letters of Credit in accordance with Issuing Lender's regularly
established practices and procedures and will have no further obligation with
respect thereto. In the administration of Letters of Credit, Issuing Lender
shall not be liable for any action taken or omitted on the advice of counsel,
accountants, appraisers or other experts selected by Issuing Lender with due
care and Issuing Lender may rely upon any notice, communication, certificate or
other statement from Borrower, beneficiaries of Letters of


                                       45

<PAGE>

Credit, or any other Person which Issuing Lender believes to be authentic.
Issuing Lender will, upon request, furnish the Revolving Credit Lenders with
copies of Letter of Credit Documents related thereto.

     (c) In connection with the issuance and administration of Letters of Credit
and the assignments hereunder, Issuing Lender makes no representation and shall
have no responsibility with respect to (i) the obligations of Borrower or the
validity, sufficiency or enforceability of any document or instrument given in
connection therewith, or the taking of any action with respect to same, (ii) the
financial condition of, any representations made by, or any act or omission of
Borrower or any other Person, or (iii) any failure or delay in exercising any
rights or powers possessed by Issuing Lender in its capacity as issuer of
Letters of Credit in the absence of its gross negligence or willful misconduct.
Each of the Revolving Credit Lenders expressly acknowledges that it has made and
will continue to make its own evaluations of Borrower's creditworthiness without
reliance on any representation of Issuing Lender or Issuing Lender's officers,
agents and employees.

     (d) If at any time Issuing Lender shall recover any part of any
unreimbursed amount for any draw or other demand for payment under a Letter of
Credit, or any interest thereon, Agent or Issuing Lender, as the case may be,
shall receive same for the pro rata benefit of the Revolving Credit Lenders in
accordance with their respective Percentages and shall promptly deliver to each
Revolving Credit Lender its share thereof, less such Revolving Credit Lender's
pro rata share of the costs of such recovery, including court costs and
attorney's fees. If at any time any Revolving Credit Lender shall receive from
any source whatsoever any payment on any such unreimbursed amount or interest
thereon in excess of such Revolving Credit Lender's Percentage of such payment,
such Revolving Credit Lender will promptly pay over such excess to Agent, for
redistribution in accordance with this Agreement.

     3.9 Indemnification. Borrower hereby indemnifies and agrees to hold
harmless the Revolving Credit Lenders, the Issuing Lender and the Agent and
their respective Affiliates, and the respective officers, directors, employees
and agents of such Persons (each an "L/C Indemnified Person"), from and against
any and all claims, damages, losses, liabilities, costs or expenses of any kind
or nature whatsoever which the Revolving Credit Lenders, the Issuing Lender or
the Agent or any such Person may incur or which may be claimed against any of
them by reason of or in connection with any Letter of Credit (collectively, the
"L/C Indemnified Amounts"), and none of the Issuing Lender, any Revolving Credit
Lender or the Agent or any of their respective officers, directors, employees or
agents shall be liable or responsible for:

          (a)  the use which may be made of any Letter of Credit or for any acts
               or omissions of any beneficiary in connection therewith;

          (b)  the validity, sufficiency or genuineness of documents or of any
               endorsement thereon, even if such documents should in fact prove
               to be in any or all respects invalid, insufficient, fraudulent or
               forged;

          (c)  payment by the Issuing Lender to the beneficiary under any Letter
               of Credit against presentation of documents which do not strictly
               comply with the terms of any Letter of Credit (unless such
               payment resulted from


                                       46

<PAGE>

               the gross negligence or willful misconduct of the Issuing
               Lender), including failure of any documents to bear any reference
               or adequate reference to such Letter of Credit;

          (d)  any error, omission, interruption or delay in transmission,
               dispatch or delivery of any message or advice, however
               transmitted, in connection with any Letter of Credit; or

          (e)  any other event or circumstance whatsoever arising in connection
               with any Letter of Credit.

It is understood that in making any payment under a Letter of Credit the Issuing
Lender will rely on documents presented to it under such Letter of Credit as to
any and all matters set forth therein without further investigation and
regardless of any notice or information to the contrary.

With respect to subparagraphs (a) through (e) hereof, (i) no Borrower shall be
required to indemnify any L/C Indemnified Person for any L/C Indemnified Amounts
to the extent such amounts result from the gross negligence or willful
misconduct of such L/C Indemnified Person or any officer, director, employee or
agent of such L/C Indemnified Person and (ii) the Agent and the Issuing Lender
shall be liable to each Borrower to the extent, but only to the extent, of any
direct, as opposed to consequential or incidental, damages suffered by Borrower
which were caused by the gross negligence or willful misconduct of the Issuing
Lender or any officer, director, employee or agent of the Issuing Lender or by
the Issuing Lender's wrongful dishonor of any Letter of Credit after the
presentation to it by the beneficiary thereunder of a draft or other demand for
payment and other documentation strictly complying with the terms and conditions
of such Letter of Credit.

     3.10 Right of Reimbursement. Each Revolving Credit Lender agrees to
reimburse the Issuing Lender on demand, pro rata in accordance with its
respective Revolving Credit Percentage, for (i) the reasonable out-of-pocket
costs and expenses of the Issuing Lender to be reimbursed by Borrower pursuant
to any Letter of Credit Agreement or any Letter of Credit, to the extent not
reimbursed by Borrower or any other Credit Party and (ii) any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, fees, reasonable out-of-pocket expenses or disbursements of any kind and
nature whatsoever which may be imposed on, incurred by or asserted against
Issuing Lender in any way relating to or arising out of this Agreement
(including Section 3.6(c) hereof), any Letter of Credit, any documentation or
any transaction relating thereto, or any Letter of Credit Agreement, to the
extent not reimbursed by Borrower, except to the extent that such liabilities,
losses, costs or expenses were incurred by Issuing Lender as a result of Issuing
Lender's gross negligence or willful misconduct or by the Issuing Lender's
wrongful dishonor of any Letter of Credit after the presentation to it by the
beneficiary thereunder of a draft or other demand for payment and other
documentation strictly complying with the terms and conditions of such Letter of
Credit.

     3.11 Existing Letters of Credit. The Existing Letters of Credit shall be
deemed for all purposes of this Agreement to be Letters of Credit, and each
application submitted in connection with the Existing Letters of Credit shall be
deemed for all purposes of this Agreement to be Letter of Credit Agreements. On
the Effective Date, the Issuing Lender shall be deemed


                                       47

automatically to have sold and transferred, and each other Revolving Credit
Lender shall be deemed automatically, irrevocably, and unconditionally to have
purchased and received from the Issuing Lender, without recourse or warranty, an
undivided interest and participation, to the extent of such other Lender's
Revolving Credit Percentage, in the Existing Letters of Credit and the
applicable Letter of Credit Obligations with respect thereto and any security
therefor or guaranty pertaining thereto. On the Effective Date, Borrower agrees
to pay to each Revolving Credit Lender (other than Comerica Bank) its pro-rata

6.   REPRESENTATIONS AND WARRANTIES.

     Borrower represents and warrants to the Agent, the Lenders, the Swing Line

<PAGE>

     6.1 Corporate Authority. Each Credit Party is a corporation (or other
business entity) duly organized and existing in good standing under the laws of
the state or jurisdiction of its incorporation or formation, as applicable, and
each Credit Party is duly qualified and authorized to do business as a foreign
corporation in each jurisdiction where the character of its assets or the nature
of its activities makes such qualification and authorization necessary except
where failure to be so qualified or be in good standing would not reasonably be
expected to have a Material Adverse Effect. Each Credit Party has all requisite
corporate, limited liability or partnership power and authority to own all its
property (whether real, personal, tangible or intangible or of any kind
whatsoever) and to carry on its business.

     6.2 Due Authorization. Execution, delivery and performance of this
Agreement, and the other Loan Documents, to which each Credit Party is party,
and the issuance of the Notes by Borrower (if requested) are within such
Person's corporate, limited liability or partnership power, have been duly
authorized, are not in contravention of any law applicable to such Credit Party
or the terms of such Credit Party's organizational documents and, except as have
been previously obtained or as referred to in Section 6.10, below, do not
require the consent or approval of any governmental body, agency or authority or
any other third party except to the extent that such consent or approval is not
material to the transactions contemplated by the Loan Documents.

     6.3 Good Title; Leases; Assets; No Liens. (a) Each Credit Party, to the
extent applicable, has good and valid title (or, in the case of real property,
good and marketable title) to all assets owned by it, subject only to the Liens
permitted under Section 8.2 hereof, and each Credit Party has a valid leasehold
or interest as a lessee or a licensee in all of its leased real property;

     (b) The Credit Parties will collectively own or collectively have a valid
leasehold interest in all assets that were owned or leased (as lessee) by the
Credit Parties immediately prior to the Effective Date to the extent that such
assets are necessary for the continued operation of the Credit Parties'
businesses in substantially the manner as such businesses were operated
immediately prior to the Effective Date;

     (c) Each Credit Party owns or has a valid leasehold interest in all real
property necessary for its continued operations and, to the best knowledge of
Borrower, no material condemnation, eminent domain or expropriation action has
been commenced or threatened against any such owned or leased real property; and

     (d) There are no Liens on and no financing statements on file with respect
to any of the assets owned by the Credit Parties, except for the Liens permitted
pursuant to Section 8.2 of this Agreement.

     6.4 Taxes. Except as set forth on Schedule 6.4 hereof, each Credit Party
has filed on or before their respective due dates or within the applicable grace
periods, all United States federal, state, local and other tax returns which are
required to be filed or has obtained extensions for filing such tax returns and
is not delinquent in filing such returns in accordance with such extensions and
has paid all material taxes which have become due pursuant to those returns or
pursuant to any assessments received by any such Credit Party, as the case may
be, to the extent


                                       51

<PAGE>

such taxes have become due, except to the extent such taxes are being contested
in good faith by appropriate proceedings diligently conducted and with respect
to which adequate provision has been made on the books of such Credit Party as
may be required by GAAP.

     6.5 No Defaults. No Credit Party is in default under or with respect to any
agreement, instrument or undertaking to which is a party or by which it or any
of its property is bound which would cause or would reasonably be expected to
cause a Material Adverse Effect.

     6.6 Enforceability of Agreement and Loan Documents. This Agreement and each
of the other Loan Documents to which any Credit Party is a party (including
without limitation, each Request for Advance), have each been duly executed and
delivered by its duly authorized officers and constitute the valid and binding
obligations of such Credit Party, enforceable against such Credit Party in
accordance with their respective terms, except as enforcement thereof may be
limited by applicable bankruptcy, reorganization, insolvency, fraudulent
conveyance, moratorium or similar laws affecting the enforcement of creditor's
rights, generally and by general principles of equity (regardless of whether
enforcement is considered in a proceeding in law or equity).

     6.7 Compliance with Laws. (a) Except as disclosed on Schedule 6.7, each
Credit Party has complied with all applicable federal, state and local laws,
ordinances, codes, rules, regulations and guidelines (including consent decrees
and administrative orders) including but not limited to Hazardous Material Laws,
and is in compliance with any Requirement of Law, except to the extent that
failure to comply therewith would not reasonably be expected to have a Material
Adverse Effect; and (b) neither the extension of credit made pursuant to this
Agreement or the use of the proceeds thereof by the Credit Parties will violate
the Trading with the Enemy Act, as amended, or any of the foreign assets control
regulations of the United States Treasury Department (31 CFR, Subtitle B,
Chapter V, as amended) or any enabling legislation or executive order relating
thereto, or The United and Strengthening America by providing appropriate Tools
Required to Intercept and Obstruct Terrorism ("USA Patriot Act") Act of 2001,
Public Law 10756, October 26, 2001 or Executive Order 13224 of September 23,
2001 issued by the President of the United States (66 Fed. Reg. 49049 (2001)).

     6.8 Non-contravention. The execution, delivery and performance of this
Agreement and the other Loan Documents (including each Request for Advance) to
which each Credit Party is a party are not in contravention of the terms of any
indenture, agreement or undertaking to which such Credit Party is a party or by
which it or its properties are bound where such violation would reasonably be
expected to have a Material Adverse Effect.

     6.9 Litigation. Except as set forth on Schedule 6.9 hereof, there is no
suit, action, proceeding, including, without limitation, any bankruptcy
proceeding or governmental investigation pending against or to the knowledge of
Borrower, threatened against any Credit Party (other than any suit, action or
proceeding in which a Credit Party is the plaintiff and in which no counterclaim
or cross-claim against such Credit Party has been filed), or any judgment,
decree, injunction, rule, or order of any court, government, department,
commission, agency, instrumentality or arbitrator outstanding against any Credit
Party, nor is any Credit Party in violation of any applicable law, regulation,
ordinance, order, injunction, decree or requirement of


                                       52

<PAGE>

any governmental body or court which would in any of the foregoing events
reasonably be expected to have a Material Adverse Effect.

     6.10 Consents, Approvals and Filings, Etc. Except as set forth on Schedule
6.10 hereof, no material authorization, consent, approval, license,
qualification or formal exemption from, nor any filing, declaration or
registration with, any court, governmental agency or regulatory authority or any
securities exchange or any other Person (whether or not governmental) is
required in connection with the execution, delivery and performance by any
Credit Party of this Agreement and any of the other Loan Documents to which such
Credit Party is a party. All such material authorizations, consents, approvals,
licenses, qualifications, exemptions, filings, declarations and registrations
which have previously been obtained or made, as the case may be, are in full
force and effect and, to the best knowledge of Borrower, are not the subject of
any attack or threatened attack (in each case in any material respect) by appeal
or direct proceeding or otherwise.

     6.11 Agreements Affecting Financial Condition. No Credit Party is party to
any agreement or instrument or subject to any charter or other corporate
restriction which could reasonably be expected to have a Material Adverse
Effect.

     6.12 No Investment Company or Margin Stock. No Credit Party is an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended. No Credit Party is engaged principally, or as one of its important
activities, directly or indirectly, in the business of extending credit for the
purpose of purchasing or carrying margin stock. None of the proceeds of any of
the Advances will be used by any Credit Party to purchase or carry margin stock.
Terms for which meanings are provided in Regulation U of the Board of Governors
of the Federal Reserve System or any regulations substituted therefore, as from
time to time in effect, are used in this paragraph with such meanings.

     6.13 ERISA. No Credit Party maintains or contributes to any Pension Plan
subject to Title IV of ERISA, except as set forth on Schedule 6.13 hereto or
otherwise disclosed to the Agent in writing. There is no material accumulated
funding deficiency within the meaning of Section 412 of the Internal Revenue
Code or Section 302 of ERISA, or any outstanding material liability with respect
to any Pension Plans owed to the PBGC other than future premiums due and owing
pursuant to Section 4007 of ERISA and any funding deficiency for which an
application to the PBGC for waiver is pending or for which a waiver has been
granted by the PBGC, and no "reportable event" as defined in Section 4043(c) of
ERISA has occurred with respect to any Pension Plan other than an event for
which the notice requirement has been waived by the PBGC. None of the Credit
Parties has engaged in a prohibited transaction with respect to any Pension
Plan, other than a prohibited transaction for which an exemption is available
and has been obtained, which would reasonably be expected to subject such Credit
Parties to a material tax or penalty imposed by Section 4975 of the Internal
Revenue Code or Section 502(i) of ERISA. Each Pension Plan is being maintained
and funded in accordance with its terms and is in material compliance with the
requirements of the Internal Revenue Code and ERISA. No Credit Party has had a
complete or partial withdrawal from any Multiemployer Plan that has resulted or
would reasonably be expected to have resulted in any Withdrawal Liability and,
except as notified to Agent in writing following the Effective Date, no such
Multiemployer


                                       53

<PAGE>

Plan is in reorganization (within the meaning of Section 4241 of ERISA) or
insolvent (within the meaning of Section 4245 of ERISA).

     6.14 Conditions Affecting Business or Properties. Neither the respective
businesses nor the properties of any Credit Party is affected by any fire,
explosion, accident, strike, lockout or other dispute, drought, storm, hail,
earthquake, embargo, Act of God, or other casualty (except to the extent such
event is covered by insurance sufficient to ensure that upon application of the
proceeds thereof, no Material Adverse Effect would reasonably be expected to
occur) which would reasonably be expected to have a Material Adverse Effect.

     6.15 Environmental and Safety Matters. Except as set forth in Schedules
6.9, 6.10 and 6.15:

          (a)  all facilities and property owned or leased by the Credit Parties
               are in material compliance with all Hazardous Material Laws;

          (b)  to the best knowledge of Borrower, there have been no material
               unresolved and outstanding past, and there are no pending or
               threatened:

               (i)  claims, complaints, notices or requests for information
                    received by any Credit Party with respect to any alleged
                    violation of any Hazardous Material Law, or

               (ii) written complaints, notices or inquiries to any Credit Party
                    regarding potential liability of any Credit Parties under
                    any Hazardous Material Law; and

          (c)  to the best knowledge of Borrower, no conditions exist at, on or
               under any property now or previously owned or leased by any
               Credit Party which, with the passage of time, or the giving of
               notice or both, are reasonably likely to give rise to liability
               under any Hazardous Material Law or create a significant adverse
               effect on the value of the property.

     6.16 Subsidiaries. Except as disclosed on Schedule 6.16 hereto as of the
Effective Date, and thereafter, except as disclosed to the Agent in writing from
time to time, no Credit Party has any Subsidiaries.

     6.17 Franchises, Patents, Copyrights, Tradenames, etc. The Credit Parties
possess all franchises, patents, copyrights, trademarks, trade names, licenses
and permits, and rights in respect of the foregoing, adequate for the conduct of
their business substantially as now conducted without known conflict with any
rights of others. Schedule 6.18 contains a true and accurate list of all trade
names and any and all other names used by Borrower and each Guarantor during the
five-year period ending as of the Effective Date.

     6.18 Accuracy of Information. (a) The audited financial statements for the
Fiscal Year ended March 31, 2007, furnished to Agent and the Lenders prior to
the Effective Date fairly present in all material respects the financial
condition of the Borrower and its Subsidiaries and the results of their
operations for the periods covered thereby, and have been prepared in


                                       54

<PAGE>

accordance with GAAP. The projections and the other pro forma financial
information delivered to the Agent prior to the Effective Date are based upon
good faith estimates and assumptions believed by management of the Borrower to
be reasonable at the time made, it being recognized by the Lenders that such
financial information as it relates to future events is not to be viewed as fact
and that actual results during the period or periods covered by such financial
information may differ from the projected results set forth therein.

     (b) From March 31, 2007 through the Effective Date, there has been no
change in the business, operations, financial condition or property of the
Credit Parties, taken as a whole, which has resulted in or would reasonably be
expected to have a Material Adverse Effect.

     (c) To the best knowledge of the Credit Parties, as of the Effective Date,
(i) the Credit Parties do not have any material contingent obligations
(including any liability for taxes) not disclosed by or reserved against in the
financial statements for the Fiscal Year ended March 31, 2007, other than those
arising in the ordinary course of business consistent with past practice
subsequent to March 31, 2007, and (ii) there are no unrealized or anticipated
losses from any present commitment of the Credit Parties which contingent
obligations and losses in the aggregate would reasonably be expected to have a
Material Adverse Effect.

     6.19 Solvency. After giving effect to the consummation of the transactions
contemplated by this Agreement and other Loan Documents, Borrower, the
Guarantors and the Credit Parties taken as a whole will be solvent, able to pay
their indebtedness as it matures and will have capital sufficient to carry on
their businesses and all business in which they are about to engage. This
Agreement is being executed and delivered by the Borrower to Agent and the
Lenders in good faith and in exchange for fair, equivalent consideration. The
Credit Parties do not intend to nor does management of the Credit Parties
believe the Credit Parties will incur debts beyond their ability to pay as they
mature. The Credit Parties do not contemplate filing a petition in bankruptcy or
for an arrangement or reorganization under the Bankruptcy Code or any similar
law of any jurisdiction now or hereafter in effect relating to any Credit Party,
nor does any Credit Party have any knowledge of any threatened bankruptcy or
insolvency proceedings against a Credit Party.

     6.20 Employee Matters. There are no strikes, slowdowns, work stoppages,
unfair labor practice complaints, grievances, arbitration proceedings or
controversies pending or, to the best knowledge of the Borrower, threatened
against any Credit Party by any employees of any Credit Party, other than
non-material employee grievances or controversies arising in the ordinary course
of business. Set forth on Schedule 6.22 are all union contracts or agreements to
which any Credit Party is party as of the Effective Date and the related
expiration dates of each such contract.

     6.21 No Misrepresentation. Neither this Agreement nor any other Loan
Document, certificate, information or report furnished or to be furnished by or
on behalf of a Credit Party to Agent or any Lender in connection with any of the
transactions contemplated hereby or thereby, contains a misstatement of material
fact, or omits to state a material fact required to be stated in order to make
the statements contained herein or therein, taken as a whole, not misleading in
the light of the circumstances under which such statements were made. There is
no fact, other than information known to the public generally, known to any
Credit Party after diligent inquiry, that


                                       55

<PAGE>

could reasonably be expect to have a Material Adverse Effect that has not
expressly been disclosed to Agent in writing.

     6.22 Corporate Documents and Corporate Existence. As to each Credit Party,
(a) it is an organization as described on Schedule 1.3 hereto and has provided
the Agent and the Lenders with complete and correct copies of its articles of
incorporation, by-laws and all other applicable charter and other organizational
documents, and, if applicable, a good standing certificate and (b) its correct
legal name, business address, type of organization and jurisdiction of
organization, tax identification number and other relevant identification
numbers are set forth on Schedule 1.3 hereto.

7.   AFFIRMATIVE COVENANTS.

     Borrower covenants and agrees, so long as any Lender has any commitment to
extend credit hereunder, or any of the Indebtedness (including reimbursement and
indemnification obligations but only to the extent the same are then due and
owing or claims therefor have been made) remains outstanding and unpaid, that it
will, and, as applicable, it will cause each of its Subsidiaries to:

               aggregate, which continues beyond any applicable period of cure
               and which would permit the holder or holders thereto to
               accelerate such other indebtedness for borrowed money, or require
               the prepayment, repurchase, redemption or defeasance of such
               indebtedness;

          (g)  the rendering of any judgment(s) (not covered by adequate

               Party for the benefit of any of its employees or for the
               appointment by the appropriate United States District Court of a
               trustee to administer such Pension Plan and such reportable event

               (within the meaning of Section 4245 of ERISA) of any
               Multiemployer Plan, or receipt of notice from any Multiemployer
               Plan that it is in reorganization or insolvency, or the complete
               or partial withdrawal by any Credit Party from any Multiemployer
               Plan, which in the case of any of the foregoing, would reasonably
               be expected to have a Material Adverse Effect;

          (i)  except as expressly permitted under this Agreement, any Credit
               Party shall be dissolved (other than a dissolution of a
               Subsidiary of Borrower which is not a Guarantor or Borrower) or

               Document), as applicable, or the validity, binding effect or
               enforceability thereof shall be contested by any party thereto
               (other than any Lender, Agent, Issuing Lender or Swing Line
               Lender), or any Borrower or any Affiliate of Borrower shall deny
               that it has any or further liability or obligation under any Loan

terminated; (b) the Agent may, and shall, upon being directed to do so by the
Majority Lenders, declare the entire unpaid principal Indebtedness, including
the Notes, immediately due and payable, without presentment, notice or demand,
all of which are hereby expressly waived by the Borrower; (c) upon the
occurrence of any Event of Default specified in Section 9.1(i) and
notwithstanding the lack of any declaration by Agent under preceding clauses (a)
or (b), the entire unpaid principal Indebtedness shall become automatically and
immediately due and payable, and the Revolving Credit Aggregate Commitment shall
be automatically and immediately terminated; (d) the Agent shall, upon being
directed to do so by the Majority Lenders, demand immediate delivery of cash
collateral, and each Borrower agrees to deliver such cash collateral upon
demand, in an amount equal to 105% of the maximum amount that may be available
to be drawn at any time prior to the stated expiry of all outstanding Letters of
Credit; (e) the Agent may, and shall, upon being directed to do so by the
Majority Lenders, notify Borrower or any Credit Party that interest shall be
payable on demand on all Indebtedness (other than Revolving Credit Advances, and

from time to time to the Agent or any Lender, at a per annum rate equal to the

and shall, upon being directed to do so by the Majority Lenders or the Lenders,
as applicable (subject to the terms hereof), exercise any remedy permitted by

exercising any right, power or privilege hereunder shall affect such right,
power or privilege, nor shall any single or partial exercise thereof preclude
any further exercise thereof, or the exercise of any other power, right or
privilege. The rights of Agent and Lenders under this Agreement are cumulative
and not exclusive of any right or remedies which Lenders would otherwise have.

     9.4 Waiver by Borrower of Certain Laws. To the extent permitted by
applicable law, each Borrower hereby agrees to waive, and does hereby absolutely
and irrevocably waive and relinquish the benefit and advantage of any valuation,
stay, appraisement, extension or redemption laws now existing or which may
hereafter exist, which, but for this provision, might be applicable to any sale
made under the judgment, order or decree of any court, on any claim for interest
on the Notes, or any security interest or mortgage contemplated by or granted
under or in connection with this Agreement. These waivers have been voluntarily
given, with full knowledge of the consequences thereof.

     9.5 Waiver of Defaults. No Event of Default shall be waived by the Lenders
except in a writing signed by an officer of the Agent in accordance with Section
13.10 hereof. No single or partial exercise of any right, power or privilege
hereunder, nor any delay in the exercise thereof, shall preclude other or
further exercise of their rights by Agent or the Lenders. No waiver of any Event
of Default shall extend to any other or further Event of Default. No forbearance
on the part of the Agent or the Lenders in enforcing any of their rights shall
constitute a waiver of any of their rights. The Borrower expressly agrees that
this Section may not be waived or modified by the Lenders or Agent by course of
performance, estoppel or otherwise.

     9.6 Set Off. Upon the occurrence and during the continuance of any Event of
Default, each Lender may at any time and from time to time, without notice to
Borrower but subject to the provisions of Section 10.3 hereof (any requirement
for such notice being expressly waived by Borrower), setoff and apply against
any and all of the obligations of Borrower now or hereafter existing under this
Agreement, whether owing to such Lender, any Affiliate of such Lender or any
other Lender or the Agent, any and all deposits (general or special, time or
demand, provisional or final) at any time held and other indebtedness at any
time owing by such Lender to or for the credit or the account of Borrower and
any property of Borrower from time to time in possession of such Lender,
irrespective of whether or not such deposits held or indebtedness owing by such
Lender may be contingent and unmatured. Promptly following any such setoff, such
Lender shall give written notice to Agent and Borrower of the occurrence
thereof. The rights of each Lender under this Section 9.6 are in addition to the
other rights and remedies (including, without limitation, other rights of
setoff) which such Lender may have.

10.  PAYMENTS, RECOVERIES AND COLLECTIONS.

     10.1 Payment Procedure.

     (a) All payments to be made by Borrower shall be made without condition or
deduction for any counterclaim, defense, recoupment or setoff. Except as
otherwise provided herein, all payments made by the Borrower of principal,
interest or fees hereunder shall be made without setoff or counterclaim on the
date specified for payment under this Agreement and must be received by Agent
not later than 1:00 p.m. (Detroit time) on the date such payment is required or
intended to be made in Dollars in immediately available funds to Agent at
Agent's office located at One Detroit Center, Detroit, Michigan 48226-3289, for
the ratable benefit of the Revolving Credit Lenders in the case of payments in
respect of the Revolving Credit and any Letter of Credit Obligations. Any
payment received by the Agent after 1:00 p.m. (Detroit time) shall be deemed
received on the next succeeding Business Day and any applicable interest or fee


                                       72

<PAGE>

shall continue to accrue. Upon receipt of each such payment, the Agent shall
make prompt payment to each applicable Lender, or, in respect of
Eurodollar-based Advances, such Lender's Eurodollar Lending Office, in like
funds and currencies, of all amounts received by it for the account of such
Lender.

     (b) Unless the Agent shall have been notified in writing by Borrower at
least two (2) Business Days prior to the date on which any payment to be made by
Borrower is due that Borrower does not intend to remit such payment, the Agent
may, in its sole discretion and without obligation to do so, assume that
Borrower has remitted such payment when so due and the Agent may, in reliance
upon such assumption, make available to each Revolving Credit Lender, on such
payment date an amount equal to such Lender's share of such assumed payment. If
Borrower has not in fact remitted such payment to the Agent, each Lender shall
forthwith on demand repay to the Agent the amount of such assumed payment made
available or transferred to such Lender, together with the interest thereon, in
respect of each day from and including the date such amount was made available
by the Agent to such Lender to the date such amount is repaid to the Agent at a
rate per annum equal to the Federal Funds Effective Rate for the first two (2)
Business Days that such amount remains unpaid, and thereafter at a rate of
interest then applicable to such Revolving Credit Advances.

     (c) Subject to the definition of "Interest Period" in Section 1 of this
Agreement, whenever any payment to be made hereunder shall otherwise be due on a
day which is not a Business Day, such payment shall be made on the next
succeeding Business Day and such extension of time shall be included in
computing interest, if any, in connection with such payment.

     (d) All payments to be made by Borrower under this Agreement or any of the
Notes (including without limitation payments under the Swing Line and/or Swing
Line Note) shall be made without setoff or counterclaim, as aforesaid, and,
subject to full compliance by each Lender (and each assignee and participant
pursuant to Section 13.8) with Section 13.13, without deduction for or on
account of any present or future withholding or other taxes of any nature
imposed by any governmental authority or of any political subdivision thereof or
any federation or organization of which such governmental authority may at the
time of payment be a member (other than any taxes on the overall income, net
income, net profits or net receipts or similar taxes (or any franchise taxes
imposed in lieu of such taxes) on the Agent or any Lender (or any branch
maintained by Agent or a Lender) as a result of a present or former connection
between the Agent or such Lender and the governmental authority, political
subdivision, federation or organization imposing such taxes), unless Borrower is
compelled by law to make payment subject to such tax. In such event, Borrower
shall:

               (i)  pay to the Agent for Agent's own account and/or, as the case
                    may be, for the account of the Lenders such additional
                    amounts as may be necessary to ensure that the Agent and/or
                    such Lender or Lenders (including the Swing Line Lender)
                    receive a net amount equal to the full amount which would
                    have been receivable had payment not been made subject to
                    such tax; and


                                       73

<PAGE>

               (ii) remit such tax to the relevant taxing authorities according
                    to applicable law, and send to the Agent or the applicable
                    Lender or Lenders (including the Swing Line Lender), as the
                    case may be, such certificates or certified copy receipts as
                    the Agent or such Lender or Lenders shall reasonably require
                    as proof of the payment by Borrower of any such taxes
                    payable by Borrower.

As used herein, the terms "tax", "taxes" and "taxation" include all taxes,
levies, imposts, duties, fees, deductions and withholdings or similar charges
together with interest (and any taxes payable upon the amounts paid or payable
pursuant to this Section 10.1) thereon. Borrower shall be reimbursed by the
applicable Lender for any payment made by Borrower under this Section 10.1 if
the applicable Lender is not in compliance with its obligations under Section
13.13 at the time of the Borrower's payment.

     10.2 Application of Payments After Event of Default. Notwithstanding
anything to the contrary in this Agreement, following the occurrence of any
Event of Default under Section 9.1(i), and following the occurrence of any other
Event of Default and the termination of the Revolving Credit Aggregate
Commitment, the acceleration of any Indebtedness arising under this Agreement or
the exercise of any other remedy in each case by the requisite Lenders under
Section 9.2 hereof, the Agent shall apply any offsets, voluntary payments by any
Credit Party or others and any other sums received or collected in respect of
the Indebtedness first, to pay all incurred and unpaid fees and reasonable
out-of-pocket expenses of the Agent under the Loan Documents, next, to pay any
fees and reasonable out-of-pocket expenses owed to the Issuing Lender hereunder,
next, to the Indebtedness under the Revolving Credit (including the Swing Line
and any Reimbursement Obligations) on a pro rata basis, next to any obligations
owing by any Credit Party under any Hedging Agreements on a pro rata basis,
next, to any other Indebtedness on a pro rata basis, and then, if there is any
excess, to the Credit Parties, as the case may be.

     10.3 Pro-rata Recovery. If any Lender shall obtain any payment or other
recovery (whether voluntary, involuntary, by application of setoff or otherwise)
on account of principal of, or interest on, any of the Advances made by it, or
the participations in Letter of Credit Obligations or Swing Line Advances held
by it in excess of its pro rata share of payments then or thereafter obtained by
all Lenders upon principal of and interest on all such Indebtedness, such Lender
shall purchase from the other Lenders such participations in the Revolving
Credit, and/or the Letter of Credit Obligation held by them as shall be
necessary to cause such purchasing Lender to share the excess payment or other
recovery ratably in accordance with the applicable Percentages of the Lenders;
provided, however, that if all or any portion of the excess payment or other
recovery is thereafter recovered from such purchasing holder, the purchase shall
be rescinded and the purchase price restored to the extent of such recovery, but
without interest.

11.  CHANGES IN LAW OR CIRCUMSTANCES; INCREASED COSTS.

     11.1 Reimbursement of Prepayment Costs. If (i) Borrower makes any payment
of principal with respect to any Eurodollar-based Advance or Quoted Rate Advance
on any day other than the last day of the Interest Period applicable thereto
(whether voluntarily, pursuant to any mandatory provisions hereof, by
acceleration, or otherwise); (ii) Borrower converts or


                                       74

<PAGE>

refunds (or attempts to convert or refund) any such Advance on any day other
than the last day of the Interest Period applicable thereto (except as described
in Section 2.5(e)); (iii) Borrower fails to borrow, refund or convert any
Eurodollar-based Advance or Quoted Rate Advance after notice has been given by
Borrower to Agent in accordance with the terms hereof requesting such Advance;
or (iv) or if the Borrower fails to make any payment of principal in respect of
a Eurodollar-based Advance or Quoted Rate Advance when due, the Borrower shall
reimburse Agent for itself and/or on behalf of any Lender, as the case may be,
within ten (10) Business Days of written demand therefor for any resulting loss,
cost or expense incurred (excluding the loss of any Applicable Margin) by Agent
and Lenders, as the case may be, as a result thereof, including, without
limitation, any such loss, cost or expense incurred in obtaining, liquidating,
employing or redeploying deposits from third parties, whether or not Agent and
Lenders, as the case may be, shall have funded or committed to fund such
Advance. The amount payable hereunder by Borrower to Agent for itself and/or on
behalf of any Lender, as the case may be, shall be deemed to equal an amount
equal to the excess, if any, of (a) the amount of interest which would have
accrued on the amount so prepaid, or not so borrowed, refunded or converted, for
the period from the date of such prepayment or of such failure to borrow, refund
or convert, through the last day of the relevant Interest Period, at the
applicable rate of interest for said Advance(s) provided under this Agreement,
over (b) the amount of interest (as reasonably determined by Agent and Lenders,
as the case may be) which would have accrued to Agent and Lenders, as the case
may be, on such amount by placing such amount on deposit for a comparable period
with leading banks in the interbank eurocurrency market. Calculation of any
amounts payable to any Lender under this paragraph shall be made as though such
Lender shall have actually funded or committed to fund the relevant Advance
through the purchase of an underlying deposit in an amount equal to the amount
of such Advance and having a maturity comparable to the relevant Interest
Period; provided, however, that any Lender may fund any Eurodollar-based Advance
or Quoted Rate Advance, as the case may be, in any manner it deems fit and the
foregoing assumptions shall be utilized only for the purpose of the calculation
of amounts payable under this paragraph. Upon any demand by Agent or a Lender
for payment under this Section 11.1, Agent and Lenders shall deliver to Borrower
a certificate prepared in good faith, setting forth in reasonable detail, the
amount of, and the basis for determining, such losses, costs and expenses, which
certificate shall be conclusively presumed correct, absent manifest error.

     11.2 Eurodollar Lending Office. For any Eurodollar Advance, if Agent or a
Lender, as applicable, shall designate a Eurodollar Lending Office which
maintains books separate from those of the rest of Agent or such Lender, Agent
or such Lender, as the case may be, shall have the option of maintaining and
carrying the relevant Advance on the books of such Eurodollar Lending Office.

     11.3 Circumstances Affecting Eurodollar-based Rate Availability. If, with
respect to any Eurodollar-Interest Period, Agent or the Majority Lenders (after
consultation with Agent) shall determine in good faith that, by reason of
circumstances affecting the foreign exchange and interbank markets generally,
deposits in eurodollars in the applicable amounts are not being offered to the
Agent or such Lenders for such Eurodollar-Interest Period, then Agent shall
forthwith give notice thereof to Borrower. Thereafter, until Agent notifies
Borrower that such circumstances no longer exist, (i) the obligation of Lenders
to make Eurodollar-based Advances, and the right of Borrower to convert an
Advance to or refund an Advance as a Eurodollar-based


                                       75

<PAGE>

Advance, as the case may be, shall be suspended, and (ii) effective upon the
last day of each Eurodollar-Interest Period related to any existing
Eurodollar-based Advance, each such Eurodollar-based Advance shall automatically
be converted into a Prime-based Advance (without regard to satisfaction of any
conditions to conversion contained elsewhere herein).

     11.4 Laws Affecting Eurodollar-based Advance Availability. If, after the
date of this Agreement, the adoption or introduction of, or any change in, any
applicable law, rule or regulation or in the interpretation or administration
thereof by any governmental authority charged with the interpretation or
administration thereof, or compliance by any of the Lenders (or any of their
respective Eurodollar Lending Offices) with any request or directive (whether or
not having the force of law) of any such authority, shall make it unlawful or
impossible for any of the Lenders (or any of their respective Eurodollar Lending
Offices) to honor its obligations hereunder to make or maintain any Advance with
interest at the Eurodollar-based Rate, such Lender shall forthwith give notice
thereof to Borrower and to Agent. Thereafter, (a) the obligations of the
applicable Lenders to make Eurodollar-based Advances and the right of Borrower
to convert an Advance into or refund an Advance as a Eurodollar-based Advance
shall be suspended and thereafter Borrower may select as Applicable Interest
Rates only those which remain available and which are permitted to be selected
hereunder, and (b) if any of the Lenders may not lawfully continue to maintain
an Advance to the end of the then current Eurodollar-Interest Period applicable
thereto as a Eurodollar-based Advance, the applicable Advance shall immediately
be converted to a Prime-based Advance and the Prime-based Rate shall be
applicable thereto for the remainder of such Eurodollar-Interest Period. For
purposes of this Section, a change in law, rule, regulation, interpretation or
administration shall include, without limitation, any change made or which
becomes effective on the basis of a law, rule, regulation, interpretation or
administration presently in force, the effective date of which change is delayed
by the terms of such law, rule, regulation, interpretation or administration.

     11.5 Increased Cost of Eurodollar-based Advances. If, after the date of
this Agreement, the adoption or introduction of, or any change in, any
applicable law, rule or regulation or in the interpretation or administration
thereof by any governmental authority, central bank or comparable agency charged
with the interpretation or administration thereof, or compliance by any of the
Lenders (or any of their respective Eurodollar Lending Offices) with any request
or directive (whether or not having the force of law) of any such authority,
central bank or comparable agency:

          (a)  shall subject any of the Lenders (or any of their respective
               Eurodollar Lending Offices) to any tax, duty or other charge with
               respect to any Advance or shall change the basis of taxation of
               payments to any of the Lenders (or any of their respective
               Eurodollar Lending Offices) of the principal of or interest on
               any Advance or any other amounts due under this Agreement in
               respect thereof (except for changes in the rate of tax on the
               overall net income of any of the Lenders or any of their
               respective Eurodollar Lending Offices); or

          (b)  shall impose, modify or deem applicable any reserve (including,
               without limitation, any imposed by the Board of Governors of the
               Federal Reserve System), special deposit or similar requirement
               against assets of, deposits


                                       76

<PAGE>

               with or for the account of, or credit extended by, any of the
               Lenders (or any of their respective Eurodollar Lending Offices)
               or shall impose on any of the Lenders (or any of their respective
               Eurodollar Lending Offices) or the foreign exchange and interbank
               markets any other condition affecting any Advance;

and the result of any of the foregoing matters is to increase the costs to any
of the Lenders of maintaining any part of the Indebtedness hereunder as a
Eurodollar-based Advance or to reduce the amount of any sum received or
receivable by any of the Lenders under this Agreement in respect of a
Eurodollar-based Advance, then such Lender shall promptly notify Agent, and
Agent shall promptly notify Borrower of such fact and demand compensation
therefor and, within ten (10) Business Days after such notice, Borrower agrees
to pay to such Lender or Lenders such additional amount or amounts as will
compensate such Lender or Lenders for such increased cost or reduction, provided
that each Lender agrees to take any reasonable action, to the extent such action
could be taken without cost or administrative or other burden or restriction to
such Lender, to mitigate or eliminate such cost or reduction, within a
reasonable time after becoming aware of the foregoing matters. Agent will
promptly notify Borrower of any event of which it has knowledge which will
entitle Lenders to compensation pursuant to this Section, or which will cause
Borrower to incur additional liability under Section 11.1 hereof, provided that
Agent shall incur no liability whatsoever to the Lenders or Borrower in the
event it fails to do so. A certificate of Agent (or such Lender, if applicable)
prepared in good faith, setting forth in reasonable detail the amount of, and
the basis for determining such additional amount or amounts necessary to
compensate such Lender or Lenders shall accompany such demand and shall be
conclusively presumed to be correct absent manifest error.

     11.6 Capital Adequacy and Other Increased Costs.

          (a)  If, after the date of this Agreement, the adoption or
               introduction of, or any change in any applicable law, treaty,
               rule or regulation (whether domestic or foreign) now or hereafter
               in effect and whether or not presently applicable to any Lender
               or Agent, or any interpretation or administration thereof by any
               governmental authority charged with the interpretation or
               administration thereof, or compliance by any Lender or Agent with
               any guideline, request or directive of any such authority
               (whether or not having the force of law), including any risk
               based capital guidelines, affects or would affect the amount of
               capital required to be maintained by such Lender or Agent (or any
               corporation controlling such Lender or Agent) and such Lender or
               Agent, as the case may be, determines that the amount of such
               capital is increased by or based upon the existence of such
               Lender's or Agent's obligations or Advances hereunder and such
               increase has the effect of reducing the rate of return on such
               Lender's or Agent's (or such controlling corporation's) capital
               as a consequence of such obligations or Advances hereunder to a
               level below that which such Lender or Agent (or such controlling
               corporation) could have achieved but for such circumstances
               (taking into consideration its policies with respect to capital
               adequacy) by an amount deemed by such Lender or Agent to be
               material (collectively, "Increased Costs"), then Agent or such
               Lender shall


                                       77

<PAGE>

               notify Borrower, and thereafter Borrower shall pay to such Lender
               or Agent, as the case may be, within ten (10) Business Days of
               written demand therefor from such Lender or Agent, additional
               amounts sufficient to compensate such Lender or Agent (or such
               controlling corporation) for any increase in the amount of
               capital and reduced rate of return which such Lender or Agent
               reasonably determines to be allocable to the existence of such
               Lender's or Agent's obligations or Advances hereunder. A
               statement setting forth the amount of such compensation, the
               methodology for the calculation and the calculation thereof which
               shall also be prepared in good faith and in reasonable detail by
               such Lender or Agent, as the case may be, shall be submitted by
               such Lender or by Agent to Borrower, reasonably promptly after
               becoming aware of any event described in this Section 11.6(a) and
               shall be conclusively presumed to be correct, absent manifest
               error.

          (b)  Notwithstanding the foregoing, however, Borrower shall not be
               required to pay any increased costs under Sections 11.5, 11.6 or
               3.4(c) for any period ending prior to the date that is 180 days
               prior to the making of a Lender's initial request for such
               additional amounts unless the applicable change in law or other
               event resulting in such increased costs is effective
               retroactively to a date more than 180 days prior to the date of
               such request, in which case a Lender's request for such
               additional amounts relating to the period more than 180 days
               prior to the making of the request must be given not more than
               180 days after such Lender becomes aware of the applicable change
               in law or other event resulting in such increased costs.

     11.7 Right of Lenders to Fund through Branches and Affiliates. Each Lender
(including without limitation the Swing Line Lender) may, if it so elects,
fulfill its commitment as to any Advance hereunder by designating a branch or
Affiliate of such Lender to make such Advance; provided that (a) such Lender
shall remain solely responsible for the performances of its obligations
hereunder and (b) no such designation shall result in any material increased
costs to Borrower.

     11.8 Margin Adjustment. Adjustments to the Applicable Margins and the
Applicable Fee Percentages, based on Schedule 1.1, shall be implemented on a
quarterly basis as follows:

          (a)  Such adjustments shall be given prospective effect only,
               effective as to all Advances outstanding hereunder, the
               Applicable Fee Percentage and the Letter of Credit Fee, upon the
               date of delivery of the financial statements under Sections
               7.1(a) and 7.1(b) hereunder and the Covenant Compliance Report
               under Section 7.2(a) hereof, in each case establishing
               applicability of the appropriate adjustment and in each case with
               no retroactivity or claw-back. In the event Borrower shall fail
               timely to deliver such financial statements or the Covenant
               Compliance Report and such failure continues for three (3) days,
               then (but without affecting the Event of Default resulting
               therefrom) from the date delivery of such financial statements
               and report was required until such financial statements and
               report are


                                       78

<PAGE>

               delivered, the Applicable Margins and Applicable Fee Percentages
               shall be at the highest level on the Pricing Matrix attached to
               this Agreement as Schedule 1.1.

          (b)  From the Effective Date until the required date of delivery (or,
               if earlier, delivery) of the financial statements under Section
               7.1(b) hereof, and the Covenant Compliance Report under Section
               7.2(a) hereof, for the fiscal quarter ending June 30, 2007, the
               Applicable Margins and Applicable Fee Percentages shall be those
               set forth under the Level I column of the pricing matrix attached
               to this Agreement as Schedule 1.1. Thereafter, Applicable Margins
               and Applicable Fee Percentages shall be based upon the quarterly
               financial statements and Covenant Compliance Reports, subject to
               recalculation as provided in Section 11.8(a) above.

          (c)  Notwithstanding the foregoing, however, if, prior to the payment
               and discharge in full (in cash) of the Indebtedness and the
               termination of any and all commitments hereunder, as a result of
               any restatement of or adjustment to the financial statements of
               Borrower and any of its Subsidiaries (relating to the current or
               any prior fiscal period) which alters the total results of the
               Borrower or any Subsidiary over a period of eight consecutive
               fiscal quarters, Agent determines that the Applicable Margin
               and/or the Applicable Fee Percentages as calculated by Borrower
               as of any applicable date of determination were inaccurate in any
               respect and a proper calculation thereof would have resulted in
               different pricing for any fiscal period, then (x) if the proper
               calculation thereof would have resulted in higher pricing for any
               such period, Borrower shall automatically and retroactively be
               obligated to pay to Agent, promptly upon demand by Agent or the
               Majority Lenders, an amount equal to the excess of the amount of
               interest and fees that should have been paid for such period over
               the amount of interest and fees actually paid for such period
               and, if the current fiscal period is affected thereby, the
               Applicable Margin and/or the Applicable Fee Percentages for the
               current period shall be adjusted based on such recalculation; and
               (y) if the proper calculation thereof would have resulted in
               lower pricing for such period, Agent and Lenders shall have no
               obligation to recalculate such interest or fees or to repay any
               interest or fees to the Borrower.

12.  AGENT.

     12.1 Appointment of Agent. Each Lender and the holder of each Note (if
issued) irrevocably appoints and authorizes the Agent to act on behalf of such
Lender or holder under this Agreement and the other Loan Documents and to
exercise such powers hereunder and thereunder as are specifically delegated to
Agent by the terms hereof and thereof, together with such powers as may be
reasonably incidental thereto, including without limitation the power to execute
or authorize the execution of financing or similar statements or notices, and
other documents. In performing its functions and duties under this Agreement,
the Agent shall act


                                       79

<PAGE>

solely as agent of the Lenders and does not assume and shall not be deemed to
have assumed any obligation towards or relationship of agency or trust with or
for any Credit Party.

     12.2 Deposit Account with Agent or any Lender. Borrower authorizes Agent
and each Lender, in Agent's or such Lender's sole discretion, upon notice to the
Borrower to charge its general deposit account(s), if any, maintained with the
Agent or such Lender for the amount of any principal, interest, or other amounts
or costs due under this Agreement when the same become due and payable under the
terms of this Agreement or the Notes.

     12.3 Scope of Agent's Duties. The Agent shall have no duties or
responsibilities except those expressly set forth herein, and shall not, by
reason of this Agreement or otherwise, have a fiduciary relationship with any
Lender (and no implied covenants or other obligations shall be read into this
Agreement against the Agent). None of Agent, its Affiliates nor any of their
respective directors, officers, employees or agents shall be liable to any
Lender for any action taken or omitted to be taken by it or them under this
Agreement or any document executed pursuant hereto, or in connection herewith or
therewith with the consent or at the request of the Majority Lenders (or all of
the Lenders for those acts requiring consent of all of the Lenders) (except for
its or their own willful misconduct or gross negligence), nor be responsible for
or have any duties to ascertain, inquire into or verify (a) any recitals or
warranties made by the Credit Parties or any Affiliate of the Credit Parties, or
any officer thereof contained herein or therein, (b) the effectiveness,
enforceability, validity or due execution of this Agreement or any document
executed pursuant hereto or any security thereunder, (c) the performance by the
Credit Parties of their respective obligations hereunder or thereunder, or (d)
the satisfaction of any condition hereunder or thereunder, including without
limitation in connection with the making of any Advance or the issuance of any
Letter of Credit. Agent and its Affiliates shall be entitled to rely upon any
certificate, notice, document or other communication (including any cable,
telegraph, telex, facsimile transmission or oral communication) believed by it
to be genuine and correct and to have been sent or given by or on behalf of a
proper person. Agent may treat the payee of any Note as the holder thereof.
Agent may employ agents and may consult with legal counsel, independent public
accountants and other experts selected by it and shall not be liable to the
Lenders (except as to money or property received by them or their authorized
agents), for the negligence or misconduct of any such agent selected by it with
reasonable care or for any action taken or omitted to be taken by it in good
faith in accordance with the advice of such counsel, accountants or experts.

     12.4 Successor Agent. Agent may resign as such at any time upon at least
thirty (30) days prior notice to Borrower and each of the Lenders. If Agent at
any time shall resign or if the office of Agent shall become vacant for any
other reason, Majority Lenders shall, by written instrument, appoint successor
agent(s) ("Successor Agent") satisfactory to such Majority Lenders and, so long
as no Default or Event of Default has occurred and is continuing, to Borrower
(which approval shall not be unreasonably withheld or delayed); provided,
however that any such successor Agent shall be a bank or a trust company or
other financial institution which maintains an office in the United States, or a
commercial bank organized under the laws of the United States or any state
thereof, or any Affiliate of such bank or trust company or other financial
institution which is engaged in the banking business, and shall have a combined
capital and surplus of at least $500,000,000. Such Successor Agent shall
thereupon become the Agent hereunder, as applicable, and Agent shall deliver or
cause to be delivered to any successor agent


                                       80

<PAGE>

such documents of transfer and assignment as such Successor Agent may reasonably
request. If a Successor Agent is not so appointed or does not accept such
appointment before the resigning Agent's resignation becomes effective, the
resigning Agent may appoint a temporary successor to act until such appointment
by the Majority Lenders and, if applicable, Borrower, is made and accepted, or
if no such temporary successor is appointed as provided above by the resigning
Agent, the Majority Lenders shall thereafter perform all of the duties of the
resigning Agent hereunder until such appointment by the Majority Lenders and, if
applicable, Borrower, is made and accepted. Such Successor Agent shall succeed
to all of the rights and obligations of the resigning Agent as if originally
named. The resigning Agent shall duly assign, transfer and deliver to such
Successor Agent all moneys at the time held by the resigning Agent hereunder
after deducting therefrom its expenses for which it is entitled to be reimbursed
hereunder. Upon such succession of any such Successor Agent, the resigning Agent
shall be discharged from its duties and obligations, in its capacity as Agent
hereunder, except for its gross negligence or willful misconduct arising prior
to its resignation hereunder, and the provisions of this Article 12 shall
continue in effect for the benefit of the resigning Agent in respect of any
actions taken or omitted to be taken by it while it was acting as Agent.

     12.5 Credit Decisions. Each Lender acknowledges that it has, independently
of Agent and each other Lender and based on the financial statements of Borrower
and such other documents, information and investigations as it has deemed
appropriate, made its own credit decision to extend credit hereunder from time
to time. Each Lender also acknowledges that it will, independently of Agent and
each other Lender and based on such other documents, information and
investigations as it shall deem appropriate at any time, continue to make its
own credit decisions as to exercising or not exercising from time to time any
rights and privileges available to it under this Agreement, any Loan Document or
any other document executed pursuant hereto.

     12.6 Authority of Agent to Enforce This Agreement. Each Lender, subject to
the terms and conditions of this Agreement, grants the Agent full power and
authority as attorney-in-fact to institute and maintain actions, suits or
proceedings for the collection and enforcement of any Indebtedness outstanding
under this Agreement or any other Loan Document and to file such proofs of debt
or other documents as may be necessary to have the claims of the Lenders allowed
in any proceeding relative to any Credit Party, or their respective creditors or
affecting their respective properties, and to take such other actions which
Agent considers to be necessary or desirable for the protection, collection and
enforcement of the Notes, this Agreement or the other Loan Documents.

     12.7 Indemnification of Agent. The Lenders agree (which agreement shall
survive the expiration or termination of this Agreement) to indemnify the Agent
and its Affiliates (to the extent not reimbursed by Borrower, but without
limiting any obligation of Borrower to make such reimbursement), ratably
according to their respective Revolving Credit Percentages, from and against any
and all claims, damages, losses, liabilities, costs or expenses of any kind or
nature whatsoever (including, without limitation, reasonable fees and expenses
of in-house and outside counsel) which may be imposed on, incurred by, or
asserted against the Agent and its Affiliates in any way relating to or arising
out of this Agreement, any of the other Loan Documents or the transactions
contemplated hereby or any action taken or omitted by the Agent and its
Affiliates under this Agreement or any of the Loan Documents; provided, however,
that


                                       81

<PAGE>

no Lender shall be liable for any portion of such claims, damages, losses,
liabilities, costs or expenses resulting from the Agent's or its Affiliate's
gross negligence or willful misconduct. Without limitation of the foregoing,
each Lender agrees to reimburse the Agent and its Affiliates promptly upon
demand for its ratable share of any reasonable out-of-pocket expenses
(including, without limitation, reasonable fees and expenses of house and
outside counsel) incurred by the Agent and its Affiliates in connection with the
preparation, execution, delivery, administration, modification, amendment or
enforcement (whether through negotiations, legal proceedings or otherwise) of,
or legal advice in respect of rights or responsibilities under, this Agreement
or any of the other Loan Documents, to the extent that the Agent and its
Affiliates are not reimbursed for such expenses by Borrower, but without
limiting the obligation of Borrower to make such reimbursement. Each Lender
agrees to reimburse the Agent and its Affiliates promptly upon demand for its
ratable share of any amounts owing to the Agent and its Affiliates by the
Lenders pursuant to this Section, provided that, if the Agent or its Affiliates
are subsequently reimbursed by Borrower for such amounts, they shall refund to
the Lenders on a pro rata basis the amount of any excess reimbursement. If the
indemnity furnished to the Agent and its Affiliates under this Section shall
become impaired as determined in the Agent's reasonable judgment or Agent shall
elect in its sole discretion to have such indemnity confirmed by the Lenders (as
to specific matters or otherwise), Agent shall give notice thereof to each
Lender and, until such additional indemnity is provided or such existing
indemnity is confirmed, the Agent may cease, or not commence, to take any
action. Any amounts paid by the Lenders hereunder to the Agent or its Affiliates
shall be deemed to constitute part of the Indebtedness hereunder.

     12.8 Knowledge of Default. It is expressly understood and agreed that the
Agent shall be entitled to assume that no Default or Event of Default has
occurred and is continuing, unless the officers of the Agent immediately
responsible for matters concerning this Agreement shall have received a written
notice from a Lender or a Borrower specifying such Default or Event of Default
and stating that such notice is a "notice of default". Upon receiving such a
notice, the Agent shall promptly notify each Lender of such Default or Event of
Default and provide each Lender with a copy of such notice and shall endeavor to
provide such notice to the Lenders within three (3) Business Days (but without
any liability whatsoever in the event of its failure to do so). The Agent shall
also furnish the Lenders, promptly upon receipt, with copies of all other
notices or other information required to be provided by Borrower hereunder.

     12.9 Agent's Authorization; Action by Lenders. Except as otherwise
expressly provided herein, whenever the Agent is authorized and empowered
hereunder on behalf of the Lenders to give any approval or consent, or to make
any request, or to take any other action on behalf of the Lenders (including
without limitation the exercise of any right or remedy hereunder or under the
other Loan Documents), the Agent shall be required to give such approval or
consent, or to make such request or to take such other action only when so
requested in writing by the Majority Lenders or the Lenders, as applicable
hereunder. Action that may be taken by the Majority Lenders, any other specified
Percentage of the Lenders or all of the Lenders, as the case may be (as provided
for hereunder) may be taken (i) pursuant to a vote of the requisite percentages
of the Lenders as required hereunder at a meeting (which may be held by
telephone conference call), provided that Agent exercises good faith, diligent
efforts to give all of the Lenders reasonable advance notice of the meeting, or
(ii) pursuant to the written consent of the requisite percentages of the Lenders
as required hereunder, provided that all of the Lenders are given reasonable
advance notice of the requests for such consent.


                                       82
<PAGE>

     12.10 Enforcement Actions by the Agent. Except as otherwise expressly
provided under this Agreement or in any of the other Loan Documents and subject
to the terms hereof, Agent will take such action, assert such rights and pursue
such remedies under this Agreement and the other Loan Documents as the Majority
Lenders or all of the Lenders, as the case may be (as provided for hereunder),
shall direct; provided, however, that the Agent shall not be required to act or
omit to act if, in the reasonable judgment of the Agent, such action or omission
may expose the Agent to personal liability for which Agent has not been
satisfactorily indemnified hereunder or is contrary to this Agreement, any of
the Loan Documents or applicable law. Except as expressly provided above or
elsewhere in this Agreement or the other Loan Documents, no Lender (other than
the Agent, acting in its capacity as agent) shall be entitled to take any
enforcement action of any kind under this Agreement or any of the other Loan
Documents.

     12.11 [Reserved]

     12.12 Agents in their Individual Capacities. Comerica Bank and its
Affiliates, successors and assigns shall each have the same rights and powers
hereunder as any other Lender and may exercise or refrain from exercising the
same as though such Lender were not the Agent. Comerica Bank and its Affiliates
may (without having to account therefor to any Lender) accept deposits from,
lend money to, and generally engage in any kind of banking, trust, financial
advisory or other business with the Credit Parties as if such Lender were not
acting as the Agent hereunder, and may accept fees and other consideration
therefor without having to account for the same to the Lenders.

     12.13 Agent's Fees. Until the Indebtedness (including reimbursement and
indemnification obligations but only to the extent the same are then due and
owing or claims therefor have been made) has been repaid and discharged in full
and no commitment to extend any credit hereunder is outstanding, Borrower shall
pay to the Agent, as applicable, any agency or other fee(s) set forth (or to be
set forth from time to time) in the applicable Fee Letter on the terms set forth
therein. The agency fees referred to in this Section 12.13 shall not be
refundable under any circumstances.

     12.14 Documentation Agent or other Titles. Any Lender identified on the
facing page or signature page of this Agreement or in any amendment hereto or as
designated with consent of the Agent in any assignment agreement as Lead
Arranger, Documentation Agent, Syndications Agent or any similar titles, shall
not have any right, power, obligation, liability, responsibility or duty under
this Agreement as a result of such title other than those applicable to all
Lenders as such. Without limiting the foregoing, the Lenders so identified shall
not have or be deemed to have any fiduciary relationship with any Lender as a
result of such title. Each Lender acknowledges that it has not relied, and will
not rely, on the Lender so identified in deciding to enter into this Agreement
or in taking or not taking action hereunder.

     12.15 No Reliance on Agent's Customer Identification Program.

          (a)  Each Lender acknowledges and agrees that neither such Lender, nor
               any of its Affiliates, participants or assignees, may rely on the
               Agent to carry out such Lender's, Affiliate's, participant's or
               assignee's customer


                                       83

<PAGE>

               identification program, or other obligations required or imposed
               under or pursuant to the Patriot Act or the regulations
               thereunder, including the regulations contained in 31 CFR 103.121
               (as hereafter amended or replaced, the "CIP Regulations"), or any
               other Anti-Terrorism Law, including any programs involving any of
               the following items relating to or in connection with Borrower or
               any of its Subsidiaries, any of their respective Affiliates or
               agents, the Loan Documents or the transactions hereunder: (i) any
               identify verification procedures, (ii) any record keeping, (iii)
               any comparisons with government lists, (iv) any customer notices
               or (v) any other procedures required under the CIP Regulations or
               such other laws.

          (b)  Each Lender or assignee or participant of a Lender that is not
               organized under the laws of the United States or a state thereof
               (and is not excepted from the certification requirement contained
               in Section 313 of the USA Patriot Act and the applicable
               regulations because it is both (i) an affiliate of a depository
               institution or foreign bank that maintains a physical presence in
               the United States or foreign country, and (ii) subject to
               provision by a banking authority regulating such affiliated
               depository institution or foreign bank) shall deliver to the
               Administrative Agent the certification, or, if applicable,
               recertification, certifying that such Lender is not a "shell" and
               certifying to other matters as required by Section 313 of the
               Patriot Act and the applicable regulations: (x) within 10 days
               after the Effective Date, and (y) at such other times as are
               required under the Patriot Act.

13. MISCELLANEOUS.

     13.1 Accounting Principles. Where the character or amount of any asset or
liability or item of income or expense is required to be determined or any
consolidation or other accounting computation is required to be made for the
purposes of this Agreement, it shall be done, unless otherwise specified herein,
in accordance with GAAP.

     13.2 Consent to Jurisdiction. The Borrower, the Agent and Lenders hereby
irrevocably submit to the non-exclusive jurisdiction of any United States
Federal Court or Michigan state court sitting in Detroit, Michigan in any action
or proceeding arising out of or relating to this Agreement or any of the Loan
Documents and the Borrower, Agent and Lenders hereby irrevocably agree that all
claims in respect of such action or proceeding may be heard and determined in
any such United States Federal Court or Michigan state court. Each Borrower
irrevocably consents to the service of any and all process in any such action or
proceeding brought in any court in or of the State of Michigan by the delivery
of copies of such process to it at the applicable addresses specified on the
signature page hereto or by certified mail directed to such address or such
other address as may be designated by it in a notice to the other parties that
complies as to delivery with the terms of Section 13.6. Nothing in this Section
shall affect the right of the Lenders and the Agent to serve process in any
other manner permitted by law or limit the right of the Lenders or the Agent (or
any of them) to bring any such action or proceeding against any Credit Party or
any of their property in the courts with subject matter jurisdiction of


                                       84

<PAGE>

any other jurisdiction. Borrower irrevocably waives any objection to the laying
of venue of any such suit or proceeding in the above described courts.

     13.3 Law of Michigan. This Agreement, the Notes and, except where otherwise
expressly specified therein to be governed by local law, the other Loan
Documents shall be governed by and construed and enforced in accordance with the
laws of the State of Michigan (without regard to its conflict of laws
provisions). Whenever possible each provision of this Agreement shall be
interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Agreement shall be prohibited by or invalid under
applicable law, such provision shall be ineffective to the extent of such
prohibition or invalidity, without invalidating the remainder of such provision
or the remaining provisions of this Agreement.

     13.4 Interest. In the event the obligation of Borrower to pay interest on
the principal balance of the Notes or on any other amounts outstanding hereunder
or under the other Loan Documents is or becomes in excess of the maximum
interest rate which Borrower is permitted by law to contract or agree to pay,
giving due consideration to the execution date of this Agreement, then, in that
event, the rate of interest applicable thereto with respect to such Lender's
applicable Percentages shall be deemed to be immediately reduced to such maximum
rate and all previous payments in excess of the maximum rate shall be deemed to
have been payments in reduction of principal and not of interest.

     13.5 Closing Costs and Other Costs; Indemnification.

     (a) Borrower shall pay or reimburse (a) Agent and its Affiliates for
payment of, on demand, all reasonable out-of-pocket costs and expenses,
including, by way of description and not limitation, reasonable in-house and
outside attorney fees and advances and accounting fees, lien search fees, and
required travel costs, incurred by Agent and its Affiliates in connection with
the commitment, consummation and closing of the loans contemplated hereby, or in
connection with the administration or enforcement of this Agreement or the other
Loan Documents (including the obtaining of legal advice regarding the rights and
responsibilities of the parties hereto) or any refinancing or restructuring of
the loans or Advances provided under this Agreement or the other Loan Documents,
or any amendment or modification thereof requested by Borrower, and (b) Agent
and its Affiliates and each of the Lenders, as the case may be, for all stamp
and other taxes and duties payable or determined to be payable in connection
with the execution, delivery, filing or recording of this Agreement and the
other Loan Documents and the consummation of the transactions contemplated
hereby, and any and all liabilities with respect to or resulting from any delay
in paying or omitting to pay such taxes or duties. Furthermore, all reasonable
out-of-pocket costs and expenses, including without limitation reasonable
attorney fees, incurred by Agent and its Affiliates and, after the occurrence
and during the continuance of an Event of Default, by the Lenders in revising,
preserving, protecting, exercising or enforcing any of its or any of the
Lenders' rights against Borrower or any other Credit Party, or otherwise
incurred by Agent and its Affiliates and the Lenders in connection with any
Event of Default or the enforcement of the loans (whether incurred through
negotiations, legal proceedings or otherwise), including by way of description
and not limitation, such charges in any court or bankruptcy proceedings or
arising out of any claim or action by any person against Agent, its Affiliates,
or any Lender which would not have been asserted were it not for Agent's or such
Affiliate's or Lender's relationship with Borrower hereunder or otherwise, shall
also be paid by


                                       85

<PAGE>

Borrower. All of said amounts required to be paid by Borrower hereunder and not
paid forthwith upon demand, as aforesaid, shall bear interest, from the date
incurred to the date payment is received by Agent, at the Prime-based Rate, plus
two percent (2%).

     (b) Borrower agrees to indemnify and hold Agent and each of the Lenders
(and their respective Affiliates) harmless from all loss, damage, liability or
reasonable out-of-pocket costs or expenses, including reasonable in-house and
outside attorneys' fees and disbursements (but without duplication of such fees
and disbursements for the same services), incurred by Agent and each of the
Lenders by reason of an Event of Default, or enforcing the obligations of any
Credit Party under this Agreement or any of the other Loan Documents, as
applicable, or in the prosecution or defense of any action or proceeding
concerning any matter growing out of or connected with this Agreement or any of
the Loan Documents, excluding, however, any loss, cost, damage, liability or
expenses to the extent arising as a result of the gross negligence or willful
misconduct of the party seeking to be indemnified under this Section 13.5(b),
provided that, the Borrower shall be obligated to reimburse Agent and the
Lenders for only a single financial consultant selected by Agent in consultation
with the Lenders.

     (c) The Borrower agrees to defend, indemnify and hold harmless Agent and
each Lender (and their respective Affiliates), and their respective employees,
agents, officers and directors from and against any and all claims, demands,
penalties, fines, liabilities, settlements, damages, and reasonable
out-of-pocket costs or expenses of whatever kind or nature (including without
limitation, reasonable attorneys and consultants fees, investigation and
laboratory fees, environmental studies required by Agent or any Lender in
connection with the violation of Hazardous Material Laws), court costs and
litigation expenses, arising out of or related to (i) the presence, use,
disposal, release or threatened release of any Hazardous Materials on, from or
affecting any premises owned or occupied by any Credit Party in violation of or
the non-compliance with applicable Hazardous Material Laws, (ii) any personal
injury (including wrongful death) or property damage (real or personal) arising
out of or related to such Hazardous Materials, (iii) any lawsuit or other
proceeding brought or threatened, settlement reached or governmental order or
decree relating to such Hazardous Materials, and/or (iv) complying or coming
into compliance with all Hazardous Material Laws (including the cost of any
remediation or monitoring required in connection therewith) or any other
Requirement of Law; provided, however, that the Borrower shall have no
obligations under this Section 13.5(c) with respect to claims, demands,
penalties, fines, liabilities, settlements, damages, costs or expenses to the
extent arising as a result of the gross negligence or willful misconduct of the
Agent or such Lender, as the case may be, or their respective agents or
employees. The obligations of Borrower under this Section 13.5(c) shall be in
addition to any and all other obligations and liabilities Borrower may have to
Agent or any of the Lenders at common law or pursuant to any other agreement.

     13.6 Notices.

               except as provided in clause (b) below), all notices and other

               or any other Loan Document shall be in writing and shall be given

               posted to an E-System set up by or at the direction of Agent (as
               set forth below) or at such other address as may be designated by

               delivery with the terms of this Section 13.6. Any notice, if
               personally delivered or if mailed and properly addressed with
               postage prepaid and sent by registered or certified mail, shall
               be deemed given when received or when delivery is refused; any
               notice, if given to a reputable overnight courier and properly
               addressed, shall be deemed given two (2) Business Days after the

               by the named addressee; and any notice, if transmitted by
               facsimile, shall be deemed given when received. The Agent may,

               it by telephone, but the giver of any such notice shall promptly
               confirm such notice in writing, by facsimile, and such notice
               will not be deemed to have been received until such confirmation

               any such confirmation, the terms of such telephonic notice shall
               control. Any notice given by the Agent or any Lender to the
               Borrower shall be deemed to be a notice to all of the Credit

               other communications to it hereunder by electronic communications
               (including email and any E-System) pursuant to procedures
               approved by it. Unless otherwise agreed to in a writing by and
               among the parties to a particular communication, (i) notices and
               other communications sent to an email address shall be deemed
               received upon the sender's receipt of an acknowledgment from the
               intended recipient (such as by the "return receipt requested"
               function, return email, or other written acknowledgment) and (ii)
               notices and other communications posted to any E-System shall be
               deemed received upon the deemed receipt by the intended recipient
               at its email address as described in the foregoing clause (i) of
               notification that such notice or other communication is available
               and identifying the website address therefore.

     13.7 Further Action. Borrower, from time to time, upon written request of
Agent will make, execute, acknowledge and deliver or cause to be made, executed,
acknowledged and delivered, all such further and additional instruments, and
take all such further action as may reasonably be required to carry out the

Advances under and payment of the Notes, according to the intent and purpose
herein and therein expressed.

     (a) This Agreement shall be binding upon and shall inure to the benefit of
the Borrower and the Lenders and their respective successors and assigns.

     (b) The foregoing shall not authorize any assignment by Borrower of its
rights or duties hereunder, and, except as otherwise provided herein, no such
assignment shall be made (or be effective) without the prior written approval of
the Lenders.

     (c) No Lenders may at any time assign or grant participations in such
Lender's rights and obligations hereunder and under the other Loan Documents
except (i) by way of assignment to any Eligible Assignee in accordance with
clause (d) of this Section, (ii) by way of a participation in accordance with
the provisions of clause (e) of this Section or (iii) by way of a pledge or
assignment of a security interest subject to the restrictions of clause (f) of
this Section (and any other attempted assignment or transfer by any Lender shall
be deemed to be null and void).

     (d) Each assignment by a Lender of all or any portion of its rights and
obligations hereunder and under the other Loan Documents, shall be subject to
the following terms and conditions:

               (i)  each such assignment shall be made on a pro rata basis, and
                    shall be in a minimum amount of the lesser of (x) Five
                    Million Dollars ($5,000,000) or such lesser amount as the
                    Agent shall agree and (y) the entire remaining amount of
                    assigning Lender's aggregate interest in the Revolving
                    Credit (and participations in any outstanding Letters of
                    Credit); provided however that, after giving effect to such
                    assignment, in no event shall the entire remaining amount
                    (if any) of assigning Lender's aggregate interest in the
                    Revolving Credit (and participations in any outstanding
                    Letters of Credit) be less than $5,000,000; and

               (ii) the parties to any assignment shall execute and deliver to
                    Agent an Assignment Agreement substantially (as determined
                    by Agent) in the form attached hereto as Exhibit F (with
                    appropriate insertions acceptable to Agent), together with a
                    processing and recordation fee in the amount, if any,
                    required as set forth in the Assignment Agreement (provided
                    however that such Lender need not deliver an Assignment
                    Agreement in connection with assignments to such Lender's
                    Affiliates or to a Federal Reserve Bank).

Until the Assignment Agreement becomes effective in accordance with its terms,
and Agent has confirmed that the assignment satisfies the requirements of this
Section 13.8, the Borrower and the Agent shall be entitled to continue to deal
solely and directly with the assigning Lender in connection with the interest so
assigned. From and after the effective date of each Assignment Agreement that
satisfies the requirements of this Section 13.8, the assignee thereunder shall
be deemed to be a party to this Agreement, such assignee shall have the rights
and obligations of a Lender under this Agreement and the other Loan Documents
(including without limitation the right to receive fees payable hereunder in
respect of the period following such assignment) and


                                       88

<PAGE>

the assigning Lender shall relinquish its rights and be released from its
obligations under this Agreement and the other Loan Documents.

     Upon request, Borrower shall execute and deliver to the Agent, new Note(s)
payable to the order of the assignee in an amount equal to the amount assigned
to the assigning Lender pursuant to such Assignment Agreement, and with respect
to the portion of the Indebtedness retained by the assigning Lender, to the
extent applicable, new Note(s) payable to the order of the assigning Lender in
an amount equal to the amount retained by such Lender hereunder. The Agent, the
Lenders and the Borrower acknowledges and agrees that any such new Note(s) shall
be given in renewal and replacement of the Notes issued to the assigning lender
prior to such assignment and shall not effect or constitute a novation or
discharge of the Indebtedness evidenced by such prior Note, and each such new
Note may contain a provision confirming such agreement.

     (e) The Borrower and the Agent acknowledge that each of the Lenders may at
any time and from time to time, subject to the terms and conditions hereof,
grant participations in such Lender's rights and obligations hereunder (on a pro
rata basis only) and under the other Loan Documents to any Person (other than a
natural person or to Borrower or any of Borrower's Affiliates or Subsidiaries);
provided that any participation permitted hereunder shall comply with all
applicable laws and shall be subject to a participation agreement that
incorporates the following restrictions:

               (i)  such Lender shall remain the holder of its Notes hereunder
                    (if such Notes are issued), notwithstanding any such
                    participation;

               (ii) a participant shall not reassign or transfer, or grant any
                    sub-participations in its participation interest hereunder
                    or any part thereof; and

               (iii) such Lender shall retain the sole right and responsibility
                    to enforce the obligations of the Credit Parties relating to
                    the Notes and the other Loan Documents, including, without
                    limitation, the right to proceed against any Guarantors, or
                    cause the Agent to do so (subject to the terms and
                    conditions hereof), and the right to approve any amendment,
                    modification or waiver of any provision of this Agreement
                    without the consent of the participant (unless such
                    participant is an Affiliate of such Lender), except for
                    those matters covered by Section 13.10(a) through (e) hereof
                    (provided that a participant may exercise approval rights
                    over such matters only on an indirect basis, acting through
                    such Lender and the Credit Parties, Agent and the other
                    Lenders may continue to deal directly with such Lender in
                    connection with such Lender's rights and duties hereunder).
                    Notwithstanding the foregoing, however, in the case of any
                    participation granted by any Lender hereunder, the
                    participant shall not have any rights under this Agreement
                    or any of the other Loan Documents against the Agent, any
                    other Lender or any Credit Party; provided, however that the
                    participant may


                                       89

<PAGE>

                    have rights against such Lender in respect of such
                    participation as may be set forth in the applicable
                    participation agreement and all amounts payable by the
                    Credit Parties hereunder shall be determined as if such
                    Lender had not sold such participation. Each such
                    participant shall be entitled to the benefits of Article 11
                    of this Agreement to the same extent as if it were a Lender
                    and had acquired its interest by assignment pursuant to
                    clause (d) of this Section, provided that no participant
                    shall be entitled to receive any greater amount pursuant to
                    such the provisions of Article 11 than the issuing Lender
                    would have been entitled to receive in respect of the amount
                    of the participation transferred by such issuing Lender to
                    such participant had no such transfer occurred and each such
                    participant shall also be entitled to the benefits of
                    Section 9.6 hereof as though it were a Lender, provided that
                    such participant agrees to be subject to Section 10.3 hereof
                    as though it were a Lender.

     (f) Any Lender may at any time pledge or assign a security interest in all
or any portion of its rights under this Agreement (including its Notes, if any)
to secure obligations of such Lender, including any pledge or assignment to
secure obligations to a Federal Reserve Bank; provided that no such pledge or
assignment shall release such Lender from any of its obligations hereunder or
substitute any such pledge or assignee for such Lender as a party hereto.

     (g) The Agent shall maintain at its principal office a copy of each
Assignment Agreement delivered to it and a register (the "Register") for the
recordation of the names and addresses of the Lenders, the Percentages of such
Lenders and the principal amount of each type of Advance owing to each such
Lender from time to time. The entries in the Register shall be conclusive
evidence, absent manifest error, and the Borrower, the Agent, and the Lenders
may treat each Person whose name is recorded in the Register as the owner of the
Advances recorded therein for all purposes of this Agreement. The Register shall
be available for inspection by the Borrower or any Lender upon reasonable notice
to the Agent and a copy of such information shall be provided to any such party
on their prior written request. The Agent shall give prompt written notice to
the Borrower of the making of any entry in the Register or any change in such
entry.

     (h) Borrower authorizes each Lender to disclose to any prospective assignee
or participant which has satisfied the requirements hereunder, any and all
financial information in such Lender's possession concerning the Credit Parties
which has been delivered to such Lender pursuant to this Agreement, provided
that each such prospective assignee or participant shall execute a
confidentiality agreement consistent with the terms of Section 13.11 hereof or
shall otherwise agree to be bound by the terms thereof.

     (i) Nothing in this Agreement, the Notes or the other Loan Documents,
expressed or implied, is intended to or shall confer on any Person other than
the respective parties hereto and thereto and their successors and assignees and
participants permitted hereunder and thereunder any benefit or any legal or
equitable right, remedy or other claim under this Agreement, the Notes or the
other Loan Documents.


                                       90

     13.9 Counterparts. This Agreement may be executed in several counterparts,
and each executed copy shall constitute an original instrument, but such
counterparts shall together constitute but one and the same instrument.

     13.10 Amendment and Waiver. No amendment or waiver of any provision of this
Agreement or any other Loan Document, nor consent to any departure by any Credit
Party therefrom, shall in any event be effective unless the same shall be in
writing and signed by the Agent and the Majority Lenders (or by the Agent at the
written request of the Majority Lenders) or, if this Agreement expressly so
requires with respect to the subject matter thereof, by all Lenders (and, with
respect to any amendments to this Agreement or the other Loan Documents, by any
Credit Party or the Guarantors that are signatories thereto), and then such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given; provided, however, that no amendment, waiver
or consent shall, unless in writing and signed by the Lender or Lenders affected
thereby, do any of the following: (a) increase the stated amount of such
Lender's commitment, (b) reduce the principal of, or interest on, any
outstanding Indebtedness or any Fees or other amounts payable hereunder, (c)
postpone any date fixed for any payment of principal of, or interest on, any
outstanding Indebtedness or any Fees or other amounts payable hereunder,
provided, however, that Agent shall be entitled without notice to or further
action or consent of the Lenders, to release any material guaranty provided by
any Person in favor of Agent and the Lenders, release any guaranty to the extent
expressly permitted in this Agreement or any of the other Loan Documents
(whether in connection with the sale, transfer or other disposition of the
applicable Guarantor or otherwise), (d) terminate or modify any indemnity
provided to the Lenders hereunder or under the other Loan Documents, except as
shall be otherwise expressly provided in this Agreement or any other Loan
Document, or (e) change the definitions of "Revolving Credit Percentage",
"Interest Periods", "Majority Lenders", Section 10.2 hereof or this Section
13.10; provided, further, that notwithstanding the foregoing, the Revolving
Credit Maturity Date may be postponed or extended only with the consent of all
of the Revolving Credit Lenders, and provided further, that no amendment, waiver
or consent shall, unless in a writing signed by the Swing Line Lender, do any of
the following: (x) reduce the principal of, or interest on, the Swing Line Note
or (y) postpone any date fixed for any payment of principal of, or interest on,
the Swing Line Note and provided further, that no amendment, waiver or consent
shall, unless in a writing signed by Issuing Lender affect the rights or duties
of Issuing Lender under this Agreement or any of the other Loan Documents and no
amendment, waiver, or consent shall, unless in a writing signed by the Agent
affect the rights or duties of the Agent under this Agreement or any other Loan
Document. All references in this Agreement to "Lenders" or "the Lenders" shall
refer to all Lenders, unless expressly stated to refer to Majority Lenders (or
the like).

     The Agent shall, upon the written request of the Borrower, execute and
deliver to the Credit Parties such documents as may be necessary to the release
of any Person from its obligations under the Loan Documents (including without
limitation the Guaranty) if all of the Equity Interests of such Person that were
held by a Credit Party are sold or otherwise transferred to any transferee other
than Borrower or a Subsidiary of Borrower as part of or in connection with any
disposition (whether by sale, by merger or by any other form of transaction)
permitted in accordance with the terms of this Agreement; provided that (i)
Agent shall not be required to execute any such release on terms which, in the
Agent's opinion, would expose the Agent to liability or create any obligation or
entail any consequence other than the release of such Liens


                                       91

<PAGE>

without recourse or warranty or such release shall not in any manner discharge,
affect or impair the Indebtedness retained by any Credit Party, including
(without limitation) the proceeds of the sale or other disposition.

     13.11 Confidentiality. Each Lender agrees that it will not disclose without
the prior consent of the Borrower (other than to its employees, its
Subsidiaries, another Lender, an Affiliate of a Lender or to its auditors or
counsel) any information with respect to the Credit Parties which is furnished
pursuant to this Agreement or any of the other Loan Documents; provided that any
Lender may disclose any such information (a) as has become generally available
to the public or has been lawfully obtained by such Lender from any third party
under no duty of confidentiality to any Credit Party, (b) as may be required or
appropriate in any report, statement or testimony submitted to, or in respect to
any inquiry, by, any municipal, state or federal regulatory body having or
claiming to have jurisdiction over such Lender, including the Board of Governors
of the Federal Reserve System of the United States, the Office of the
Comptroller of the Currency or the Federal Deposit Insurance Corporation or
similar organizations (whether in the United States or elsewhere) or their
successors, (c) as may be required or appropriate in respect to any summons or
subpoena or in connection with any litigation, (d) in order to comply with any
law, order, regulation, ruling or other requirement of law applicable to such
Lender, and (e) to any prospective assignee or participant in accordance with
Section 13.8(e) hereof.

     13.12 Substitution of Lenders. If (a) any Lender has failed to fund its
Revolving Credit Percentage of any Revolving Credit Advance, or to fund a
Revolving Credit Advance to repay a Swing Line Advance or any Reimbursement
Obligations, (b) the obligation of any Lender to make Eurodollar-based Advances
has been suspended pursuant to Section 11.3 or 11.4, (c) any Lender has demanded
compensation under Section 3.4(d), 11.5 or 11.6 or (d) any Lender has not
approved an amendment, waiver or other modification of this Agreement and the
consent of such Lender is required (in each case, an "Affected Lender"), then
the Agent or the Borrower shall have the right to make written demand on the
Affected Lender (with a copy to the Borrower in the case of a demand by the
Agent or with a copy to the Agent in the case of a demand by the Borrower) to
assign and the Affected Lender shall assign, to one or more financial
institutions that comply with the provisions of Section 13.8 hereof (the
"Purchasing Lender" or "Purchasing Lenders") to purchase the Advances of the
Revolving Credit, and/or Swing Line, as the case may be, of such Affected Lender
(including, without limitation, its participating interests in outstanding Swing
Line Advances and Letters of Credit) and assume the commitment of the Affected
Lender to extend credit under the Revolving Credit (including without limitation
its obligation to purchase participations interest in Swing Line Advances and
Letters of Credit) under this Agreement. The Affected Lender shall be obligated
to sell its Advances of the Revolving Credit and/or the Swing Line, as the case
may be, and assign its commitment to extend credit under the Revolving Credit
(including without limitation its obligations to purchase participations in
Swing Line Advances and Letters of Credit) to such Purchasing Lender or
Purchasing Lenders within ten (10) days after receiving notice from the Borrower
requiring it to do so, at an aggregate price equal to the outstanding principal
amount thereof, plus unpaid interest accrued thereon up to but excluding the
date of the sale. In connection with any such sale, and as a condition thereof,
the Borrower shall pay to the Affected Lender all fees accrued for its account
hereunder to but excluding the date of such sale, plus, if demanded by the
Affected Lender within ten (10) Business Days after such sale, (i) the amount of
any


                                       92

<PAGE>

compensation which would be due to the Affected Lender under Section 11.1 if the
Borrower had prepaid the outstanding Eurodollar-based Advances of the Affected
Lender on the date of such sale and (ii) any additional compensation accrued for
its account under Sections 3.4(d), 11.5 and 11.6 to but excluding said date.
Upon such sale, the Purchasing Lender or Purchasing Lenders shall assume the
Affected Lender's commitment, and the Affected Lender shall be released from its
obligations hereunder to a corresponding extent. If any Purchasing Lender is not
already one of the Lenders, the Affected Lender, as assignor, such Purchasing
Lender, as assignee, the Borrower and the Agent, shall enter into an Assignment
Agreement pursuant to Section 13.8 hereof, whereupon such Purchasing Lender
shall be a Lender party to this Agreement, shall be deemed to be an assignee
hereunder and shall have all the rights and obligations of a Lender with a
Revolving Credit Percentage equal to its ratable share of the then applicable
Revolving Credit Aggregate Commitment of the Affected Lender. In connection with
any assignment pursuant to this Section 13.12, the Borrower or the Purchasing
Lender shall pay to the Agent the administrative fee for processing such
assignment referred to in Section 13.8.

     13.13 Withholding Taxes. If any Lender is not a "United States person"
within the meaning of Section 7701(a)(30) of the Internal Revenue Code, such
Lender shall promptly (but in any event prior to the initial payment of interest
hereunder or prior to its accepting any assignment under Section 13.8 hereof, as
applicable) deliver to the Agent two executed copies of (i) Internal Revenue
Service Form W-8BEN or any successor form specifying the applicable tax treaty
between the United States and the jurisdiction of such Lender's domicile which
provides for the exemption from withholding on interest payments to such Lender,
(ii) Internal Revenue Service Form W-8ECI or any successor form evidencing that
the income to be received by such Lender hereunder is effectively connected with
the conduct of a trade or business in the United States or (iii) other evidence
satisfactory to the Agent that such Lender is exempt from United States income
tax withholding with respect to such income; provided, however, that such Lender
shall not be required to deliver to Agent the aforesaid forms or other evidence
with respect to Advances to Borrower, if such Lender has assigned its entire
interest hereunder (including its Revolving Credit Commitment Amount, any
outstanding Advances hereunder and participations in Letters of Credit issued
hereunder and any Notes issued to it by Borrower), to an Affiliate which is
incorporated under the laws of the United States or a state thereof, and so
notifies the Agent. Such Lender shall amend or supplement any such form or
evidence as required to insure that it is accurate, complete and non-misleading
at all times. Promptly upon notice from the Agent of any determination by the
Internal Revenue Service that any payments previously made to such Lender
hereunder were subject to United States income tax withholding when made, such
Lender shall pay to the Agent the excess of the aggregate amount required to be
withheld from such payments over the aggregate amount actually withheld by the
Agent. In addition, from time to time upon the reasonable request and the sole
expense of Borrower, each Lender and the Agent shall (to the extent it is able
to do so based upon applicable facts and circumstances), complete and provide
Borrower with such forms, certificates or other documents as may be reasonably
necessary to allow Borrower, as applicable, to make any payment under this
Agreement or the other Loan Documents without any withholding for or on the
account of any tax under Section 10.1(d) hereof (or with such withholding at a
reduced rate), provided that the execution and delivery of such forms,
certificates or other documents does not adversely affect or otherwise restrict
the rights and benefits (including without limitation economic benefits)
available to such Lender or the Agent, as the case may be, under this Agreement
or any of the


                                       93

<PAGE>

other Loan Documents, or under or in connection with any transactions not
related to the transactions contemplated hereby.

     13.14 Taxes and Fees. Should any tax (other than as a result of a Lender's
failure to comply with Section 13.13 or a tax based upon the net income or
capitalization of any Lender or the Agent by any jurisdiction where a Lender or
the Agent is or has been located), or recording or filing fee become payable in
respect of this Agreement or any of the other Loan Documents or any amendment,
modification or supplement hereof or thereof, Borrower agrees to pay the same,
together with any interest or penalties thereon arising from Borrower's actions
or omissions, and agrees to hold the Agent and the Lenders harmless with respect
thereto provided, however, that Borrower shall not be responsible for any such
interest or penalties which were incurred prior to the date that notice is given
to the Credit Parties of such tax or fees. Notwithstanding the foregoing,
nothing contained in this Section 13.14 shall affect or reduce the rights of any
Lender or the Agent under Section 11.5 hereof.

     13.15 WAIVER OF JURY TRIAL. THE LENDERS, THE AGENT AND THE BORROWER
KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHT ANY OF THEM MAY HAVE TO
A TRIAL BY JURY IN ANY LITIGATION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR
ANY RELATED INSTRUMENT OR AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED BY
THIS AGREEMENT OR ANY COURSE OF CONDUCT, DEALING, STATEMENTS (WHETHER ORAL OR
WRITTEN) OR ACTION OF ANY OF THEM. NEITHER THE LENDERS, THE AGENT NOR THE
BORROWER SHALL SEEK TO CONSOLIDATE, BY COUNTERCLAIM OR OTHERWISE, ANY SUCH
ACTION IN WHICH A JURY TRIAL HAS BEEN WAIVED WITH ANY OTHER ACTION IN WHICH A
JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED. THESE PROVISIONS SHALL NOT BE
DEEMED TO HAVE BEEN MODIFIED IN ANY RESPECT OR RELINQUISHED BY THE LENDERS AND
THE AGENT OR THE BORROWER EXCEPT BY A WRITTEN INSTRUMENT EXECUTED BY ALL OF
THEM.

     13.16 Patriot Act Notice. Pursuant to Section 326 of the USA Patriot Act,
the Agent and the Lenders hereby notify the Credit Parties that if they or any
of their Subsidiaries open an account, including any loan, deposit account,
treasury management account, or other extension of credit with Agent or any
Lender, the Agent or the applicable Lender will request the applicable Person's
name, tax identification number, business address and other information
necessary to identify such Person (and may request such Person's organizational
documents or other identifying documents) to the extent necessary for the Agent
and the applicable Lender to comply with the USA Patriot Act.

     13.17 Complete Agreement; Conflicts. This Agreement, the Notes (if issued),
any Requests for Revolving Credit Advance, and Requests for Swing Line Advance,
and the Loan Documents contain the entire agreement of the parties hereto,
superseding all prior agreements, discussions and understandings relating to the
subject matter hereof, and none of the parties shall be bound by anything not
expressed in writing. In the event of any conflict between the terms of this
Agreement and the other Loan Documents, this Agreement shall govern.


                                       94

     13.18 Severability. In case any one or more of the obligations of any of
the parties under this Agreement, the Notes or any of the other Loan Documents
shall be invalid, illegal or unenforceable in any jurisdiction, the validity,
legality and enforceability of the remaining obligations of the parties shall
not in any way be affected or impaired thereby, and such invalidity, illegality
or unenforceability in one jurisdiction shall not affect the validity, legality
or enforceability of the obligations of the parties under this Agreement, the
Notes or any of the other Loan Documents in any other jurisdiction.

     13.19 Table of Contents and Headings; Section References. The table of
contents and the headings of the various subdivisions hereof are for convenience
of reference only and shall in no way modify or affect any of the terms or
provisions hereof and references herein to "sections," "subsections," "clauses,"

subsections, clauses, paragraphs, subparagraphs, exhibits and schedules,
respectively, of this Agreement unless otherwise specifically provided herein or
unless the context otherwise clearly indicates.

     13.20 Construction of Certain Provisions. If any provision of this
Agreement or any of the Loan Documents refers to any action to be taken by any
Person, or which such Person is prohibited from taking, such provision shall be

Ladies and Gentlemen:

     Reference is made to Section 13.8 of the Credit Agreement. Unless otherwise
defined herein or the context otherwise requires, all initially capitalized
terms used herein without definition shall have the meanings specified in the
Credit Agreement.

     This Agreement constitutes notice to each of you of the proposed assignment
and delegation by [insert assignor Lender] (the "Assignor") to [insert proposed
assignee] (the "Assignee"), and, subject to the terms and conditions of the
Credit Agreement, the Assignor hereby sells and assigns to the Assignee, and the
Assignee hereby purchases and assumes from the Assignor, effective on the
Effective Date (as hereafter defined) that undivided interest in each of
Assignor's rights and obligations under the Credit Agreement and the other Loan
Documents in the amounts as set forth on the attached Schedule 1, such that,
after giving effect to the foregoing assignment and assumption, and the
concurrent assignment by Assignor to Assignee on the date hereof, the Assignee's
interest in the Revolving Credit.

     The Assignor hereby instructs the Agent to make all payments from and
including the Effective Date hereof in respect of the interest assigned hereby,
directly to the Assignee. The Assignor and the Assignee agree that all interest
and fees accrued up to, but not including, the Effective Date of the assignment
and delegation being made hereby are the property of the Assignor, and not the
Assignee. The Assignee agrees that, upon receipt of any such interest or fees
accrued up to the Effective Date, the Assignee will promptly remit the same to
the Assignor.

     The Assignee hereby confirms that it has received a copy of the Credit
Agreement and the exhibits and schedules referred to therein, and all other Loan
Documents which it considers necessary, together with copies of the other

under the Credit Agreement as a condition to the making of the loans thereunder.
The Assignee acknowledges and agrees that it: (a) has made and will continue to
make such inquiries and has taken and will take such care on its own behalf as
would have been the case had its Percentage been granted and its loans been made
directly by such Assignee to the Borrower without the intervention of the Agent,
the Assignor or any other Lender; and (b) has made and will continue to make,
independently and without reliance upon the Agent, the Assignor or any other
Lender, and based on such documents and information as it has deemed
appropriate, its own credit analysis and decisions relating to the Credit
Agreement. The Assignee further acknowledges and agrees that neither the Agent,
nor the Assignor has made any representations or warranties about the
creditworthiness of the Borrower or any other party to the Credit Agreement or
any other of the Loan Documents, or with respect to the legality, validity,
sufficiency or enforceability of the Credit Agreement, or any other of the Loan
Documents. This assignment shall be made without recourse to or warranty by the
Assignor, except as set forth herein.

     Assignee represents and warrants that it is a Person to which assignments
are permitted pursuant to Section 13.8 of the Credit Agreement.

     Except as otherwise provided in the Credit Agreement, effective as of the
Effective Date:

     (b)  the Assignee: (i) shall be deemed automatically to have become a party
          to the Credit Agreement and the other Loan Documents, to have assumed
          all of the Assignor's obligations thereunder to the extent of the
          Assignee's percentage referred to in the second paragraph of this
          Assignment Agreement, and to have all the rights and obligations of a
          party to the Credit Agreement and the other Loan Documents, as if it
          were an original signatory thereto to the extent specified in the
          second paragraph hereof; and (ii) agrees to be bound by the terms and
          conditions set forth in the Credit Agreement and the other Loan
          Documents as if it were an original signatory thereto; and

     (c)  the Assignor's obligations under the Credit Agreement and the other
          Loan Documents shall be reduced by the Percentage referred to in the
          second paragraph of this Assignment Agreement.

     As used herein, the term "Effective Date" means the date on which all of
the following have occurred or have been completed, as reasonably determined by
the Agent:

     (1)  the delivery to the Agent of an original of this Assignment Agreement
          executed by the Assignor and the Assignee;

     (2)  the payment to the Agent, of all accrued fees, expenses and other
          items for which reimbursement is then owing under the Credit
          Agreement;

     (3)  the payment to the Agent of the processing fee in the amount of
          $3,500; and

     (4)  all other restrictions and items noted in Section 13.8 of the Credit
          Agreement have been completed.

The Agent shall notify the Assignor and the Assignee, along with Borrower, of

                               (Imanage # 788222)
<PAGE>

                                    GUARANTY

     This GUARANTY is made as of this 1st day of November, 2007 by the

Revolving Credit Agreement dated as of November 1, 2007 (as amended,

jointly.

     E. The Agent is acting as agent for the Lenders pursuant to SECTION 11.1 of

Lenders in accordance with the Credit Agreement. In addition, the following term
shall have the following meaning:

<PAGE>

     "GUARANTEED OBLIGATIONS" shall mean, collectively, all indebtedness,
     liabilities and obligations of the Borrower to the Lenders of every kind,
     nature or description under the Credit Agreement or any other Loan
     Document, including, without limitation, principal, interest (including
     interest accruing on or after the filing of any petition in bankruptcy, or
     the commencement of any insolvency, reorganization or like proceeding by or
     against the Borrower, whether or not a claim for post-filing or
     post-petition interest is allowed in such a proceeding and including,
     without limitation, interest at the highest allowable per annum rate
     specified in any document, instrument or agreement applicable to any of the
     indebtedness), reimbursement obligations, fees, indemnities, and reasonable
     out-of-pocket costs and expenses (including without limitation, all
     reasonable fees and disbursements of counsel to the Agent or any Lender) or
     otherwise, and any liabilities of Borrower to Agent or any Lender arising
     in connection with any Lender Products and payment obligations of Borrower
     to Agent or any Lender arising under Hedging Transactions evidenced by
     Hedging Agreements, and any and all other liabilities and obligations,
     direct or indirect, absolute or contingent, due or to become due, now
     existing or hereafter incurred, which may arise under, out of, or in
     connection with the Credit Agreement and the other Loan Documents, whether
     such indebtedness is now existing or hereafter arising, and shall be deemed
     to include all Indebtedness, as defined in the Credit Agreement.

     2. GUARANTY. Each of the Guarantors hereby, jointly and severally,
guarantees to the Lenders the due and punctual payment to the Lenders when due,
whether by acceleration or otherwise, of the Guaranteed Obligations. Each of
such Guarantors further jointly and severally agree to pay any and all
reasonable out-of-pocket expenses (including reasonable attorneys' fees), that
may be paid or incurred by the Agent or any Lender in enforcing or preserving
rights with respect to or collecting any or all of the Guaranteed Obligations
and/or enforcing any rights with respect to, or collecting against the
Guarantors under this Guaranty.

     3. UNCONDITIONAL CHARACTER OF GUARANTY. The obligations of each of the
Guarantors under this Guaranty shall be absolute and unconditional, and shall be
a guaranty of payment and not of collection, irrespective of the validity,
regularity or enforceability of the Credit Agreement or any of the other Loan
Documents, or any provision thereof, the absence of any action to enforce the
same, any waiver or consent with respect to or any amendment of any provision
thereof (provided that any amendment of this Guaranty shall be in accordance
with the terms hereof), the recovery of any judgment against any Person or
action to enforce the same, any failure or delay in the enforcement of the
obligations of the Borrower under the Credit Agreement or any of the other Loan
Documents, or any setoff, counterclaim, recoupment, limitation, defense or
termination whether with or without notice to the Guarantors. Each of the
Guarantors hereby waives diligence, demand for payment, filing of claims with
any court, any proceeding to enforce any provision of the Credit Agreement or
any of the other Loan Documents, any right to require a proceeding first against
the Borrower or against any other Guarantor or other Person providing
collateral, or to exhaust any security for the performance of the obligations of
the Borrower, any protest, presentment, notice or demand whatsoever, and each
Guarantor hereby covenants that this Guaranty shall not be terminated,
discharged or released until, subject to SECTION 16 hereof, final payment in
full of all of the Guaranteed Obligations (including reimbursement and
indemnification obligations but only to the extent the


                                       2

<PAGE>

same are then due and owing or claims therefor have been made) due and to become
due from the Borrower, no Letters of Credit shall be outstanding and the
termination of any and all commitments to extend credit (whether optional or
obligatory) under the Credit Agreement or any other Loan Document, and only to
the extent of any such payment, performance and discharge. Each Guarantor hereby
further covenants that no security now or subsequently held by the Agent or the
Lenders for the payment of the Guaranteed Obligations (including, without
limitation, any security for any of the foregoing), whether in the nature of a
security interest, pledge, lien, assignment, setoff, suretyship, guaranty,
indemnity, insurance or otherwise, and no act, omission or other conduct of the
Agent or the Lenders in respect of such security, shall affect in any manner
whatsoever the unconditional obligations of this Guaranty, and that the Agent
and each of the Lenders in their respective sole discretion and without notice
to any of the Guarantors, may release, exchange, enforce, apply the proceeds of
and otherwise deal with any such security without affecting in any manner the
unconditional obligations of this Guaranty.

     Without limiting the generality of the foregoing, the obligations of the
Guarantors under this Guaranty, and the rights of the Agent to enforce the same,
on behalf of the Lenders by proceedings, whether by action at law, suit in
equity or otherwise, shall not be in any way affected to the extent permitted by
applicable law, by (i) any insolvency, bankruptcy, liquidation, reorganization,
readjustment, composition, dissolution, winding up or other proceeding involving
or affecting the Borrower, any or all of the Guarantors or any other Person or
any of their respective Affiliates including any discharge of, or bar or stay
against collecting, all or any of the Guaranteed Obligations in or as a result
of any such proceeding; (ii) any change in the ownership of any of the capital
stock (or other ownership interests) of the Borrower or any or all of the
Guarantors, or any other Person providing collateral for any of the Guaranteed
Obligations, or any of their respective Affiliates; (iii) the election by the
Agent or any Lender, in any bankruptcy proceeding of any Person, to apply or not
apply Section 1111(b)(2) of the Bankruptcy Code; (iv) any extension of credit or
the grant of any security interest or lien under Section 364 of the Bankruptcy
Code; (v) any agreement or stipulation with respect to the provision of adequate
protection in any bankruptcy proceeding of any Person; (vi) the avoidance of any
security interest or lien in favor of the Agent or any Lender for any reason;
(vii) any action taken by the Agent or any Lender that is authorized by this
paragraph or any other provision of this Guaranty; or (viii) any other principle
or provision of law, statutory or otherwise, which is or might be in conflict
with the terms hereof.

     4. WAIVERS. Each of the Guarantors hereby waives to the fullest extent
possible under applicable law:

          (a) any defense based upon the doctrine of marshaling of assets or
upon an election of remedies by Agent or the Lenders, including, without
limitation, an election to proceed by non-judicial rather than judicial
foreclosure;

          (b) any defense based upon any statute or rule of law which provides
that the obligation of a surety must be neither larger in amount nor in other
respects more burdensome than that of the principal;

          (c) any duty on the part of Agent or any of the Lenders to disclose to
such Guarantor any facts Agent or the Lenders may now or hereafter know about
the Borrowers,


                                       3

<PAGE>

regardless of whether Agent or any Lender has reason to believe that any such
facts materially increase the risk beyond that which such Guarantor intends to
assume or has reason to believe that such facts are unknown to such Guarantor or
has a reasonable opportunity to communicate such facts to such Guarantor;

          (d) any other event or action (excluding compliance by such Guarantor
with the provisions hereof) that would result in the discharge by operation of
law or otherwise of such Guarantor from the performance or observance of any
obligation, covenant or agreement contained in this Guaranty; and

          (e) all rights to participate in any security now or hereafter held by
the Agent or any Lender.

     Each of the Guarantors acknowledges and agrees that this is a knowing and
informed waiver of the undersigned's rights as discussed above and that the
Agent and the Lenders are relying on this waiver in extending credit to the
Borrower.

     5. WAIVER OF SUBROGATION. Each Guarantor hereby waives any claim for
reimbursement, contribution, exoneration, indemnity or subrogation, or any other
similar claim, which such Guarantor may have or obtain against the Borrower, by
reason of the existence of this Guaranty, or by reason of the payment by such
Guarantor of any of the Guaranteed Obligations or the performance of this
Guaranty, the Credit Agreement or any of the other Loan Documents, until the
Guaranteed Obligations (including reimbursement and indemnification obligations
but only to the extent the same are then due and owing or claims therefor have
been made) have been repaid and discharged in full, no Letters of Credit shall
remain outstanding and all commitments to extend credit under the Credit
Agreement or any of the other Loan Documents (whether optional or obligatory)
have been terminated. Any amounts paid to such Guarantor on account of any such
claim at any time when the obligations of such Guarantor under this Guaranty
shall not have been fully and finally paid shall be held by such Guarantor in
trust for Agent and the Lenders, segregated from other funds of such Guarantor,
and forthwith upon receipt by such Guarantor shall be turned over to Agent in
the exact form received by such Guarantor (duly endorsed to Agent by such
Guarantor, if required), to be applied to such Guarantor's obligations under
this Guaranty, whether matured or unmatured, in such order and manner as Agent
may determine.

     Each of the Guarantors acknowledges and agrees that this is a knowing and
informed waiver of the undersigned's rights as discussed above and that the
Agent and the Lenders are relying on this waiver in extending credit to the
Borrower.

     6. OTHER TRANSACTIONS. The Agent and each of the Lenders may deal with the
Borrower and any security held by them for the obligations of the Borrower in
the same manner and as freely as if this Guaranty did not exist and the Agent
shall be entitled, on behalf of the Lenders, without notice to any of the
Guarantors, among other things, to grant to the Borrower such extension or
extensions of time to perform any act or acts as may seem advisable to the Agent
(on behalf of the Lenders) at any time and from time to time, and to permit the

     17. CONSENT TO JURISDICTION. Each of the Guarantors hereby irrevocably
submits to the non-exclusive jurisdiction of any United States federal or
Michigan state court sitting in Detroit in any action or proceeding arising out
of or relating to this Guaranty or any of the other Loan Documents and
Guarantors hereby irrevocably agree that all claims in respect of such action or
proceeding may be heard and determined in any such United States federal or
Michigan state court. Each of the Guarantors irrevocably consents to the service
of any and all process in any such action or proceeding brought in any court in
or of the State of Michigan (and to the receipt of any and all notices
hereunder) by the delivery of copies of such process to Guarantors at their
respective addresses specified in SCHEDULE 1 hereof in the manner set forth
therein.

     18. HEADINGS. The headings, captions, and arrangements used in this
Guaranty are for convenience only and shall not affect the interpretation of
this Guaranty.

     19. COUNTERPARTS. This Guaranty may be executed in any number of

together shall constitute one and the same instrument.

     20. JURY TRIAL WAIVER. EACH OF THE GUARANTORS (AND THE AGENT AND EACH OF
THE LENDERS BY ACCEPTING THE BENEFITS HEREOF) HEREBY IRREVOCABLY AGREES TO WAIVE
THE RIGHT TO TRIAL BY JURY WITH RESPECT TO ANY AND ALL ACTIONS OR PROCEEDINGS IN
WHICH THE AGENT OR THE LENDERS (OR ANY OF THEM), ON ONE HAND, AND THE BORROWER

ACTIONS OR PROCEEDINGS ARISE OUT OF THIS GUARANTY OR THE OTHER LOAN DOCUMENTS OR
OTHERWISE.

     21. LIMITATION UNDER APPLICABLE INSOLVENCY LAWS. Notwithstanding anything
to the contrary contained herein, it is the intention of the Guarantors, the
Agent and the Lenders that the amount of the respective Guarantor's obligations
hereunder shall be in, but not in excess of, the maximum amount thereof not
subject to avoidance or recovery by operation of applicable law governing
bankruptcy, reorganization, arrangement, adjustment of debts, relief of debtors,
dissolution, insolvency, fraudulent transfers or conveyances or other similar
laws (collectively, "APPLICABLE INSOLVENCY LAWS"). To that end, but only in the
event and to the extent that the Guarantor's respective obligations hereunder or
any payment made pursuant thereto would, but for the operation of the foregoing
proviso, be subject to avoidance or recovery under Applicable Insolvency Laws,
the amount of the Guarantor's respective obligations hereunder shall be limited
to the largest amount which, after giving effect thereto, would not, under
Applicable Insolvency Laws, render the Guarantor's respective obligations
hereunder unenforceable or avoidable or subject to recovery under Applicable
Insolvency Laws. To the extent any payment actually made hereunder exceeds the
limitation contained in this SECTION 21, then the amount of such excess shall,
from and after the time of payment by the Guarantors (or any of them), be
reimbursed by the Lenders upon demand by such Guarantors. The foregoing proviso
is intended solely to preserve the rights of the Agent and the Lenders hereunder
against the Guarantors to the maximum extent permitted by Applicable Insolvency
Laws and neither the Borrower nor any Guarantor nor any other Person shall have
any right or claim under this SECTION 21 that would not otherwise be available
under Applicable Insolvency Laws.

                                   WITNESSETH:

     WHEREAS, the Credit Agreement provides in Section 2.13 thereof that a
financial institution, although not originally a party thereto, may become a

     Except as otherwise provided in the Credit Agreement, effective as of the
Effective Date (as defined below):

          (a) the New Lender (i) shall be deemed automatically to have become a
party to the Credit Agreement and the other Loan Documents, and to have all the
rights and

<PAGE>

obligations of a party to the Credit Agreement and the other Loan Documents, as
if it were an original signatory; and (ii) agrees to be bound by the terms and
conditions set forth in the Credit Agreement and the other Loan Documents as if
it were an original signatory thereto; and

          (b) the New Lender shall be a Lender and its Percentage of the
Revolving Credit (and its risk participation in Letters of Credit) shall be as
set forth in the attached revised Schedule 1.2 (Percentages and Commitments);
provided any fees paid prior to the Effective Date, including any Letter of
