Agent,

22

 

Person authorized (in a similar writing delivered to the Agent) by the Borrowers to make such requests and, in the event Agent, acting on behalf of the Revolving Credit Banks, makes any such Advance
upon a telephone request, the requesting officer shall fax to Agent, on the same day as such telephone request, a Request for Advance. The Borrowers hereby authorize Agent to disburse Advances under
this Section 2.3 pursuant to the telephone instructions of any Person purporting to be a Person authorized by the Borrowers in the manner set forth above. Notwithstanding the foregoing, the
Company acknowledges that the Borrowers shall bear all risk of loss resulting from disbursements made upon any telephone request. Each telephone request for an Advance 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 a Borrower under Section 2.3 hereof, Agent shall promptly notify each Revolving Credit Bank by
facsimile wire, telex or facsimile (confirmed by wire, telecopy or telex) of the amount of such Advance to be made and the date such Advance is to be made by said Revolving Credit Bank pursuant to its
Percentage of such Advance. Unless such Revolving Credit Bank's commitment to make Advances of the Revolving Credit hereunder shall have been suspended or terminated in accordance with this Agreement,
each such
Revolving Credit Bank shall make available the amount of its Percentage of each Advance in immediately available funds to Agent, as follows: 

        (i)    for
Domestic Advances, at the office of Agent located at One Detroit Center, Detroit, Michigan 48226, not later than 3:00 p.m. (Detroit time) on the date of such
Advance; and 

        (ii)  for
Eurocurrency-based Advances, at the Agent's Correspondent for the account of the Eurocurrency Lending Office of the Agent, not later than 12 noon (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 a Borrower without exceptions noted in the compliance certification therein, Agent shall
make available to the Borrower, the aggregate of the amounts so received by it from the Revolving Credit Banks in like funds and currencies: 

        (i)    for
Domestic Advances, not later than 4:00 p.m. (Detroit time) on the date of such Advance by credit to an account of the Borrowers maintained with Agent or to
such other account or third party as the Borrowers may reasonably direct; and 

        (ii)  for
Eurocurrency-based Advances, not later than 4:00 p.m. (the time of the Agent's Correspondent) on the date of such Advance, by credit to an account of the
Borrowers maintained with Agent's Correspondent or to such other account or third party as the Borrowers may reasonably direct. 

        (c)  Agent
shall deliver the documents and papers received by it for the account of each Revolving Credit Bank to such Revolving Credit Bank or upon its order. Unless Agent
shall have been notified by any Revolving Credit Bank prior to the date of any proposed Revolving Credit Advance that such Revolving Credit Bank does not intend to make available to Agent such
Revolving Credit Bank's Percentage of such Advance, Agent may assume that such Revolving Credit Bank has made such amount available to Agent on such date, as aforesaid and may, in reliance upon such
assumption, make available to the Borrowers a corresponding amount. If such amount is not in fact made available to Agent by such Revolving Credit Bank, as aforesaid, Agent shall be entitled to
recover such amount on demand from such Revolving Credit Bank. If such Revolving Credit Bank does not pay such amount forthwith upon Agent's demand therefor and the Agent has in fact made a
corresponding amount available to the Borrowers, the Agent shall 

23

 

promptly notify the Borrowers and the Borrowers shall pay such amount to Agent, if such notice is delivered to the Borrowers 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, provided that any such payment by the Borrowers shall not relieve a Defaulting Bank of its obligation to fund hereunder. Agent shall
also be entitled to recover from such Revolving Credit Bank or the Borrowers, 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 the Borrowers, to the date such amount is recovered by Agent, at a rate per annum
equal to: 

        (i)    in
the case of such Revolving Credit Bank, for the first two (2) Business Days such amount remains unpaid, with respect to Domestic Advances, the Federal Funds
Effective Rate, and with respect to Eurocurrency-based Advances, Agent's aggregate marginal cost (including the cost of maintaining any required reserves or deposit insurance and of any fees,
penalties, overdraft charges or other costs or expenses incurred by Agent as a result of such failure to deliver funds hereunder) of carrying such amount and thereafter, at the rate of interest then
applicable to such Revolving Credit Advances; and 

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

The
obligation of any Revolving Credit Bank to make any Advance of the Revolving Credit hereunder shall not be affected by the failure of any other Revolving Credit Bank to make any Advance hereunder,
and no Revolving Credit Bank shall have any liability to the Company or any of its Subsidiaries, the Agent, any other Revolving Credit Bank, or any other party for another Revolving Credit Bank's
failure to make any loan or Advance hereunder. In the event any Bank shall fail to advance any amounts required to be advanced in accordance with the terms of this Article 2 (a "Defaulting
Bank"), the Agent shall promptly provide written notice thereof to the Borrowers and to each other Bank (each such other Bank being referred to in this Section as a "Non-Defaulting Bank").
Each Non-Defaulting Bank shall have ten (10) Business Days from receipt of said notice to exercise its option to agree to enter into an agreement pursuant to which the
Non-Defaulting Bank shall assume the Defaulting Bank's rights and obligations under this Agreement, its Notes and the other Loan Documents. The Non-Defaulting Bank shall
exercise such option by providing written notice of same to the Defaulting Bank (and if there is more than one Non-Defaulting Bank, the assignment agreement shall be entered into with the
Non-Defaulting Bank who first notifies the Defaulting Bank of its decision to exercise said option) and to the Borrowers. If no Non-Defaulting Bank shall exercise the
above-described option within the said ten (10) Business Day period and if the Borrowers shall, subject to Section 13.8(c) hereof, within thirty (30) days of delivering the notice
described above, advise such Defaulting Bank of another bank or financial institution to which assignments are permitted pursuant to Section 13.8(c) hereof and which is willing to assume such
Defaulting Bank's rights and obligations under this Agreement, its Notes and the other Loan Documents (each such bank or financial institution being hereinafter referred to as a "Potential Financial
Institution"), such Defaulting Bank shall, subject to Section 13.8(c), assign its said rights and obligations to the Potential Financial Institution; provided however that any such assignment
shall not alter the Borrowers' remedies vis a vis the Defaulting Bank. 

        2.5    Swing Line Advances.    The Swing Line Bank shall, on the terms and subject to the conditions hereinafter set
forth (including without limitation Section 2.5(c) hereof), make one or more advances (each such advance being a "Swing Line Advance") to the Borrowers, from time to time on any Business Day
during the period from the date hereof to (but excluding) the Revolving Credit Maturity Date in an amount not to exceed in the aggregate at any time outstanding the Swing Line Maximum Amount. Swing
Line Bank shall maintain in accordance with its usual practice an account or accounts evidencing indebtedness of the Borrowers to Swing Line Bank resulting from each Swing Line Advance 

24

 

of such Bank from time to time, including the amounts of principal and interest payable thereon and paid to such Bank from time to time. The entries made in such account or accounts of Swing Line
Bank shall, to the extent permitted by applicable law, be conclusive evidence, absent manifest error, of the existence and amounts of the obligations of the Borrowers therein recorded; provided,
however, that the failure of Swing Line Bank to maintain such account, as applicable, or any error therein, shall not in any manner affect the obligation of the Borrowers to repay the Swing Line
Advances (and all other amounts owing with respect thereto) made to Company by Swing Line Bank in accordance with the terms of this Agreement. Advances, repayments and readvances under the Swing Line
may be made, subject to the terms and conditions of this Agreement. Each Swing Line Advance shall mature and the principal amount thereof shall be due and payable by the Borrowers in the case of any
Quoted Rate Advance, on the last day of the Interest Period applicable thereto (if any) and, in the case of any Prime-based Advance, on the Revolving Credit Maturity Date. 

        The
Borrowers agree that, upon the written request of Swing Line Bank, the Borrowers will execute and deliver to Swing Line Bank a Swing Line Note; provided, that the delivery of such
Swing Line Note shall not be a condition precedent to the Effective Date. 

        (a)    Accrual of Interest.    Each Swing Line Advance shall, from time to time after the date of such Advance, bear
interest at its Applicable Interest Rate. 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 shall be
noted on Swing Line Bank's account maintained pursuant to Section 2.5, which records will be conclusive evidence thereof, absent manifest error; provided, however, that any failure by the Swing
Line Bank to record any such information shall not relieve the Borrowers of their obligation to repay the outstanding principal amount of such Advance, all interest accrued thereon and any amount
payable with respect thereto in accordance with the terms of this Agreement and the other Loan Documents. 

        (b)    Requests for Swing Line Advances.    The Borrowers may request a Swing Line Advance only after the delivery to
Swing Line Bank of a Request for Swing Line Advance executed by a person authorized (in a writing a copy of which has been previously delivered to the Agent) by the Borrowers to make such requests,
subject to the following: 

        (i)    each

principal amount of all Swing Line Advances outstanding on such date shall not exceed the Swing Line Maximum Amount. 

        (iii)  on
the proposed date of such Swing Line Advance, after giving effect to all Advances and Letters of Credit requested by the Borrowers on such date (including, without
duplication, deemed Advances made under Section 3.6(a) hereof in respect of a Borrower's or an applicable Account Party's reimbursement obligation hereunder) of determination, the sum of
(x) the aggregate principal amount of all Advances of the Revolving Credit and of the Swing Line requested or outstanding on such date plus (y) the Letter of Credit Obligations on such
date shall not exceed the Revolving Credit Aggregate Commitment; 

25

 

        (iv)  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 agreed to by Swing Line Bank from time to time. 

        (v)  in
the case of a Swing Line Advance that is a Quoted Rate Advance, the principal amount of such Advance plus any other outstanding Advances of the Swing Line to be then
combined therewith having the same Applicable Interest Rate and Interest Period, if any, shall be at least Two Hundred Fifty Thousand Dollars ($250,000) (or a larger integral multiple of ($10,000) or
such lesser amount as agreed to by Swing Line Bank from time to time, and at any one time there shall not be in effect more than 3 Applicable Interest Rates and Interest Periods; 

        (vi)  each

binding and enforceable obligations of such Loan Parties; 

        (B)  all
conditions to the making of Swing Line Advances have been satisfied (both before and after giving effect to such Advance); 

        (C)  both
before and after giving effect to such Swing Line Advance, there is no Default or Event of Default in existence; and 

        (D)  both
before and after giving effect to such Swing Line Advance, the representations and warranties contained in this Agreement and the other Loan Documents are true and
correct in all material respects, other than any representation or warranty that expressly speaks only as of a different date. 

        At
the option of the Swing Line Bank, subject to revocation by Swing Line Bank at any time and from time to time, the Borrowers may utilize the Swing Line Bank's "Sweep to Loan"
automated system for obtaining Swing Line Advances. Each time a Swing Line Advance is made using the "Sweep to Loan" system, the Borrowers shall be deemed to have certified to the Swing Line Bank and
the Banks each of the matters set forth in clause (vi) of this Section 2.5(b). Swing Line Bank may revoke the Borrowers' 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 the Borrowers for the funding of Swing Line Advances hereunder (or
otherwise) and the regular procedures set forth for the making of Swing Line Advances shall be deemed immediately to apply. Swing Line Bank may, at its option, also elect to make Swing Line Advances
upon a Borrower's telephone requests on the basis set forth in the post-amble to Section 2.3 hereof, provided that the Borrowers comply with the provisions set forth in
Section 2.3. 

        Swing
Line Bank, may also, at its option, lend under this Section 2.5(c) upon the telephone request of a Responsible Officer or other Person authorized (in a corporate resolution
or similar writing delivered to Agent) by the Borrowers and, in the event Swing Line Bank makes any such Advance upon a telephone request, the requesting officer shall, if so requested by Swing Line
Bank, fax to Swing Line Bank, on the same day as such telephone request, a Request for Swing Line Advance. Borrowers hereby authorize Swing Line Bank to disburse Advances under this
Section 2.5(c) pursuant to the telephone instructions of any Person purporting to be a Person authorized by the Borrowers in the manner set forth above. Notwithstanding the foregoing, the
Borrowers acknowledge that each 

26

 

Borrower shall bear all risk of loss resulting from disbursements made upon any telephone request. Each telephone request for an Advance shall constitute a certification of the matters set forth in
the Request for Swing Line Advance form as of the date of such requested Advance. Swing Line Bank shall promptly deliver to Agent by telecopy a copy of any Request for Advance received hereunder. 

        (c)    Disbursement of Swing Line Advances.    Subject to submission of an executed Request for Swing Line Advance by
a Borrower without exceptions noted in the compliance certification therein, Swing Line Bank shall make available to the applicable Borrower the amount so requested, in like funds and currencies, not
later than 4:00 p.m. (Detroit time) on the date of such Advance by credit to an account of the Borrowers maintained with Agent or to such other account or third party as the Borrowers may
reasonably direct in writing. 

Swing
Line Bank shall promptly notify Agent of any Swing Line Advance by telephone, telex or facsimile. 

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

        (i)    The
Agent, at any time in its sole and absolute discretion, may, and, if properly requested by the Borrowers to do so by submission of a duly executed Request for
Advance complying with Section 2.3 hereof, shall in each case on behalf of the Borrowers (which hereby irrevocably directs the Agent to act on its behalf for such purpose, which direction shall
remain in effect unless and until the Revolving Credit has been terminated by the Borrowers under Section 2.14 hereof) request each of the Revolving Credit Banks (including the Swing Line Bank
in its capacity as a Revolving Credit Bank) to make an Advance of the Revolving Credit to the Borrowers, in an amount equal to such Revolving Credit Bank's Percentage of the principal amount of the
aggregate Swing Line Advances outstanding on the date such notice is given (the "Refunded Swing Line Advances"); provided however that Swing Line Advances which are carried at the Quoted Rate which
are converted to Revolving Credit Advances at the request of the Agent 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 Bank against the Borrowers or the Revolving Credit Banks as a consequence of such conversion. In the case of each Refunded Swing Line
Advance the applicable Advance of the Revolving Credit used to refund such Swing Line Advance shall be a Prime-based Advance. 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(d)(ii) hereof, the Swing Line Bank shall retain its claim against the Borrowers 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(j) hereof shall have occurred (in which event the procedures of subparagraph
(ii) of this Section 2.5(d) shall apply) and regardless of whether the conditions precedent set forth in this Agreement to the making of an Advance of the Revolving Credit are then
satisfied but subject to Section 2.5(d)(iii), each Revolving Credit Bank shall make the proceeds of its Advance of the Revolving Credit available to the Agent for the benefit of the Swing Line
Bank at the office of the Agent specified in Section 2.4(a) hereof prior to 11:00 a.m. Detroit time (for Domestic Advances) on the Business Day next succeeding the date such notice is
given, in immediately available funds. The proceeds of such Advances of the Revolving Credit shall be immediately applied to repay the Refunded Swing Line Advances in accordance with the provisions of
Section 10.1 hereof. 

        (ii)  If,
prior to the making of an Advance of the Revolving Credit pursuant to subparagraph (i) of this Section 2.5(d), one of the events described in
Section 9.1(j) hereof shall have occurred, each Revolving Credit Bank will, on the date such Advance of the Revolving Credit was to have been made, purchase from the Swing Line Bank an
undivided participating interest in each Swing Line Advance that was to
have been refunded in an amount equal to its Percentage of such Swing Line Advance. Each Revolving Credit Bank within the time periods specified in 

27

 

Section 2.5(d)(i) hereof, as applicable, shall immediately transfer to the Agent, in immediately available funds, the amount of its participation and upon receipt thereof the Agent will
deliver to such Revolving Credit Bank a Swing Line Participation Certificate in the form of Exhibit E evidencing such participation. 

        (iii)  Each
Revolving Credit Bank's obligation to make Advances of the Revolving Credit and to purchase participation interests in accordance with clauses (i) and
(ii) of this Section 2.5(d) shall be absolute and unconditional and shall not be affected by any circumstance, including, without limitation, (i) any set-off,
counterclaim, recoupment, defense or other right which such Revolving Credit Bank may have against Swing Line Bank, any Borrower or any other Person for any reason whatsoever; (ii) the
occurrence or continuance of any Default or Event of Default; (iii) any adverse change in the condition (financial or otherwise) of any Borrower or any other Person; (iv) any breach of
this Agreement by any Borrower or any other Person; (v) any inability of any Borrower to satisfy the conditions precedent to borrowing set forth in this Agreement on the date upon which such
Advance is to be made or such participating interest is to be purchased; (vi) the termination of the Revolving Credit Aggregate Commitment hereunder; or (vii) any other circumstance,
happening or event whatsoever, whether or not similar to any of the foregoing. If any Revolving Credit Bank does not make available to the Agent the amount required pursuant to clause (i) or
(ii) above, as the case may be, the Agent shall be entitled to recover such amount on demand from such Revolving Credit Bank, together with interest thereon for each day from the date of
non-payment 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 Bank to make available its pro rata portion of the amounts required
pursuant to clause (i) or (ii) above shall not be affected by the failure of any other Revolving Credit Bank to make such amounts available, and no Revolving Credit Bank shall have any
liability to the Company and its Subsidiaries, the Agent, the Swing Line Bank, or any other Revolving Credit Bank or any other party for another Revolving Credit Bank's failure to make the amounts
required under clause (i) or (ii) available. 

        2.6    Prime-based Interest Payments.    Interest on the unpaid balance of all Prime-based Advances of the Revolving
Credit and all Swing Line Advances carried at the Prime-based Rate 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 the first day of the calendar quarter next succeeding the calendar quarter during which the initial Advance of
the Revolving Credit or Swing Line Advance, as the case may be, is made and on the first day of each calendar quarter thereafter. 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. 

        2.7    Eurocurrency-based Interest Payments and Quoted Rate Interest Payments.    

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

        (b)  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 

28

 

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. 

        2.8    Interest Payments on Conversions.    Notwithstanding anything to the contrary in the preceding sections, all
accrued and unpaid interest on any Advance refunded or converted pursuant to Section 2.3 or 2.5(d) hereof (except for refundings or conversions of Prime-based Advances) shall be due and payable
in full on the date such Advance is refunded or converted. 

        2.9    Interest on Default.    In the event and so long as any Event of Default shall exist, in the case of any Event
of Default under Sections 9.1(a) or 9.1(j), immediately upon the occurrence thereof, and in the case of all other Events of Default, upon notice from the Majority Revolving Credit Banks, interest
shall be payable on demand on all Eurocurrency-based Advances of the Revolving Credit and Quoted Rate Advances from time to time outstanding (and, to the extent delinquent, on all other monetary
obligations of the Borrowers hereunder and under the other Loan Documents) at a per annum rate equal to the Applicable Interest Rate in respect of each such Advance plus, in the case of
Eurocurrency-based 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%). 

        2.10    Optional Prepayments.    (a) Except as provided in Section 2.10(b) hereof, the Borrowers may prepay all
or part of the outstanding principal of any Prime-based Advance(s) of the Revolving Credit at any time, provided that, unless the "Sweep to Loan" system shall be in effect under Section 2.5(b)
hereof, the amount of any partial prepayment shall be at least One Hundred Thousand Dollars ($100,000) and, after giving effect to any such partial prepayment, the aggregate balance of Prime-based
Advance(s) of the Revolving Credit remaining outstanding, if any, shall be at least Five Hundred Thousand Dollars ($500,000). Subject to Section 11.1 hereof and to the other terms and
conditions of this Agreement, the Borrowers may prepay all or part of any Eurocurrency-based Advance of the Revolving Credit (subject to not less than one (1) Business Day's notice to Agent)
provided that the amount of any such partial prepayment shall be at least Two Hundred Fifty Thousand Dollars ($250,000), and after giving effect to any such partial prepayment, the unpaid portion of
such Advance which is refunded or converted under Section 2.3 hereof shall be at least One Million Dollars ($1,000,000). 

        (b)  The
Borrowers 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, unless the "Sweep
to Loan" system shall be in effect under Section 2.5 hereof, the amount of any partial prepayment shall be at least Ten Thousand Dollars ($10,000) and, after giving effect to any such partial
prepayment, the aggregate balance of such Swing Line Advances remaining outstanding, if any, shall be at least Ten Thousand Dollars ($10,000). 

        (c)  The
Borrowers may prepay at any time all or part of the outstanding principal of any Swing Line Advance carried at the Quoted Rate (subject to not less than one
(1) day's notice to the Swing Line Bank) provided that the amount of such prepayment shall be at least Ten Thousand Dollars ($10,000) and, after giving effect to any such partial prepayment,
the aggregate unpaid portion of such Swing Line Advance shall be at least Fifty Thousand Dollars ($50,000). 

        (d)  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, but otherwise without premium or penalty. 

29

   
        2.11    Prime-based Advance in Absence of Election or Upon Default.    If, (a) as to any outstanding
Eurocurrency-based Advance of the Revolving Credit, 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(c) hereof with respect to the refunding or conversion of such Advance, or (b) subject to
Section 2.9 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 Eurocurrency-based Advance which has not been prepaid shall, absent a contrary election of the Majority Revolving Credit Banks, be converted automatically to a
Prime-based Advance and the Agent shall thereafter promptly notify the Borrowers of said action. 

        2.12    Revolving Credit Facility Fee.    From the Effective Date to the Revolving Credit Maturity Date, the Borrowers
shall pay to the Agent for distribution to the Revolving Credit Banks pro-rata in accordance with their respective Percentages, a Revolving Credit Facility Fee quarterly in arrears
commencing July 1, 2002 (in respect of the prior fiscal quarter or portion thereof), and on the first day of each fiscal quarter thereafter. The Revolving Credit Facility Fee payable to each
Revolving Credit Bank shall be determined by multiplying the Applicable Fee Percentage times 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. 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. Upon receipt of such payment, Agent shall make prompt payment to each
Revolving Credit Bank 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. 

        2.13    Mandatory Repayment of Revolving Credit Advances/Mandatory Reduction of Revolving Credit Aggregate
Commitment.    

        (a)  If
at any time and for any reason the aggregate outstanding principal amount of Revolving Credit Advances plus Swing Line Advances hereunder to the Borrowers, plus the
outstanding Letter of Credit Obligations, shall exceed the Revolving Credit Aggregate Commitment, the Borrowers 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, immediately repay an amount of the Indebtedness equal to such excess and, to the extent such Indebtedness consists of
Letter of Credit Obligations, provide cash collateral on the basis set forth in Section 9.2 hereof. The Borrowers acknowledge that, in connection 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; provided,
however, that the Borrowers shall, in order to reduce any such prepayment costs and expenses, first prepay such portion of the Indebtedness then carried as a Prime-based Advance, if any; 

        (b)  In
the event that, after giving effect to any mandatory prepayment under Section 4.13 hereof, the Indebtedness under the Term Loan has been paid and discharged in
full (or is covered by cash collateral), then subject to clause (e) hereof, immediately upon receipt by the Company or any Subsidiary of Net Cash Proceeds from the issuance of any Equity
Interests of such Person other than Equity Interests issued to employees under the stock option or employee incentive plans listed on Schedule 6.23 hereto (or any successor plans) or pursuant
to any option or warrant originally issued to employees under such plans or pursuant to those options or warrants issued in connection with prior acquisitions and described on
Schedule 2.13/4.13 hereto, or from the issuance of any Subordinated Debt, other than Funded Debt (which is Subordinated Debt) permitted under Sections 8.1(c) and (j) or which does not
yield cash proceeds to the Company or a Subsidiary, issued after the Effective Date by such Person, the Borrowers shall be obligated to 

30

 

permanently reduce the amount of the Revolving Credit Aggregate Commitment by an amount equal to (y) fifty percent (50%) of such cash proceeds in the case of any other issuance of Equity
Interests or (z) one hundred percent (100%) of any such issuance of Subordinated Debt (net, in any case, of reasonable and customary costs and expenses of issuance) which, in each case, remain
after giving effect to any prepayment under Section 4.13, provided that no such commitment reduction shall occur if the amount of such reduction resulting from a transaction or related series
of transactions would be less than $50,000; 

        (c)  In
the event that, after giving effect to any mandatory prepayment under Section 4.13(c) hereof, the Indebtedness under the Term Loan has been paid and discharged
in full (or is covered by cash collateral), then subject to clause (e) hereof, immediately upon receipt by the Company or any Subsidiary of any Net Cash Proceeds from Asset Sales, the Borrowers
shall be obligated to permanently reduce the amount of the Revolving Credit Aggregate Commitment by an amount equal to one hundred percent (100%) of such Net Cash Proceeds, provided that no such
commitment reduction shall occur if the amount of such reduction resulting from a transaction or related series of transactions would be less than $50,000; 

        (d)  The
reductions of the Revolving Credit Aggregate Commitment pursuant to clause (b) and (c) above shall be accompanied in each case by prepayments of
principal sufficient to reduce the outstanding principal balance under the Revolving Credit (taking into account outstanding Letters of Credit and Swing Line Advances) to an amount not greater than
the Commitment, as so reduced; and 

        (e)  To
the extent that, on the date any mandatory repayment of the Revolving Credit Advances under this Section 2.13 or payment pursuant to the terms of any of the
Collateral 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 Eurocurrency-based Rate and no Default or
Event of Default has occurred and is continuing, the Borrowers 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 Banks (which shall be an interest-bearing account), on such terms and conditions as are reasonably acceptable to
Agent and upon such deposit the obligation of the Borrowers 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 Interest Period attributable to the
Eurocurrency-based Advances of such Revolving Advance, thereby avoiding breakage costs under Section 11.1 hereof. 

        2.14    Optional Reduction or Termination of Revolving Credit Aggregate Commitment.    The Borrowers 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 One Million Dollars ($1,000,000) or a larger integral
multiple of Five Hundred Thousand Dollars ($500,000); (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) the Borrowers shall prepay in accordance with the terms hereof the amount, if any, by which the aggregate unpaid principal amount of Advances (including, without
duplication, any deemed Advances made under Section 3.6 hereof) outstanding hereunder, plus the aggregate undrawn amount of outstanding 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 Commitment
unless the Borrowers so elect; provided, however that if the termination or reduction of the Revolving Credit Aggregate 

31

 

Commitment requires the prepayment of a Eurocurrency-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 Eurocurrency-based Advance or such Quoted Rate Advance, then, pursuant to Section 11.1, the Borrowers shall compensate the Revolving Credit Banks for any
losses or, the Borrowers may deposit the amount of such prepayment in a collateral account as provided in Section 2.13(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 Bank in accordance with such Revolving Credit Bank's Percentage thereof, and will
not be available for reinstatement by or readvance to the Borrowers, and any accompanying prepayments of Advances of the Swing Line shall be distributed by Agent to the Swing Line Bank and will not be
available for reinstatement by or readvance to the Borrowers. Any reductions of the Revolving Credit Aggregate Commitment hereunder shall reduce each Revolving Credit Bank'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, next to Eurocurrency-based Advances of the Revolving Credit and then to Swing Line Advances carried at the
Quoted Rate. 

        2.15    Use of Proceeds of Advances.    Advances of the Revolving Credit (including Swing Line Advances) shall be
available for general corporate purposes of Company and its Subsidiaries including the financing of capital expenditures and working capital needs. 

        2.16    Extensions of Revolving Credit Maturity Date.    (a) Provided that no Default or Event of Default has
occurred and is continuing, the Borrowers may, by written notice to Agent and each Bank (which notice shall be irrevocable) prior to April 30, but not before April 1, of each year
beginning in 2003, request that the Banks 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 (each such
request, a "Request"). 

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

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

        (d)  Each
Bank which elects not to extend the Revolving Credit Maturity Date or fails to so notify the Agent of such consent (a "Non-Consenting Bank") hereby
agrees that if any other Bank or financial institution acceptable to the Borrowers and the Agent offers to purchase such Non-Consenting Bank's Percentage of the Revolving Credit Aggregate
Commitment within 180 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 Bank, such Non-Consenting Bank will promptly assign, sell
and transfer all of its right, title, interest and obligations with respect to the foregoing to such other Bank or financial institution pursuant to and on the terms specified in the form of
Assignment Agreement attached hereto as Exhibit I. Before assigning to a financial institution other than a Lender pursuant to this clause (d), each Bank that has elected to extend the
Revolving Credit Maturity Date (a "Consenting Bank") shall have the right, but not any obligation, pro rata with all other Consenting 

32

 

Banks which elect to purchase a pro rata share of such non-consenting Bank's Percentage of the Revolving Credit Aggregate Commitment (and participations in Swing Line Advances and Letters
of Credit) to purchase each such Non-Consenting Bank's Percentage thereof pursuant to this clause (d). The Consenting Banks which elect to exercise their purchase options hereunder
shall by mutual agreement determine the amount of each Non-Consenting Bank's Percentage of the Revolving Credit Aggregate Commitment being purchased by each Consenting Bank, provided that
if there is any dispute among the Consenting Banks such purchase shall be based upon a pro rata sharing of each Non-Consenting Bank's Percentage thereof. Only if the Consenting Banks have
determined not to purchase all of the Non-Consenting Bank's Revolving Credit Aggregate Commitment may financial institutions other than a Consenting Bank then purchase such
Non-Consenting Bank'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 Banks have consented to the extension
or if another Bank or financial institution has purchased each such Non-Consenting Bank'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 Banks under Section 2.16(d) hereof or otherwise, Banks holding eighty percent (80%) or more of
the Percentages (the "Approving Percentages") have consented to an extension of the Revolving Credit Maturity Date hereunder, and Company has advised Agent, in writing, of its election to proceed such
extension shall become effective, notwithstanding that all of the Banks have failed to approve such extension in accordance with this Section 2.16, so long as the Borrowers, prior thereto,
reduce 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 repay the
Indebtedness then outstanding hereunder (and, if necessary cause any outstanding Letters of 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 Banks shall have been paid and discharged in full. Reductions of the Revolving
Credit Aggregate Commitment made under this Section 2.16 (f) may be made without regard to the notice provisions set forth in Section 2.16 hereof, but shall otherwise comply with
said Section 2.16, except that any amounts repaid by the Borrowers against the Indebtedness pursuant to this subparagraph (f) shall be first applied to the Indebtedness outstanding to
the Non-Consenting Banks still holding Indebtedness hereunder at such time, with any remaining amounts applied in accordance with Section 2.16 hereof and the Percentages held by
such Non-Consenting Banks shall be reallocated to the Consenting Banks (giving effect to any assignments, as aforesaid), pro rata, based on the Percentages then in effect and Agent shall
distribute to the remaining Banks a revised Schedule 1.2 reflecting such reallocated Percentages. 

3.    LETTERS OF CREDIT

not having the force of law) shall prohibit or request that Issuing Bank refrain from issuing, or any Revolving Credit Bank refrain from taking an assignment of its Percentage of, the Letter of Credit
requested or letters of credit generally; 

        (g)  there
shall have been no introduction of or change in the interpretation of any law or regulation that would make it unlawful or unduly burdensome for the Issuing Bank
to issue or any 

34

 

Revolving Credit Bank to take an assignment of its Percentage of the requested Letter of Credit, no declaration of a general banking moratorium by banking authorities in the United States, Michigan
or the respective jurisdictions in which the Revolving Credit Banks, the applicable Account Party and the beneficiary of the requested Letter of Credit are located, and no establishment of any new
restrictions by any central bank or other governmental agency or authority on transactions involving letters of credit or on banks materially affecting the extension of credit by banks; and 

        (h)  Issuing
Bank shall have received the issuance fees required in connection with the issuance of such Letter of Credit pursuant to Section 3.4 hereof. 

Each
Letter of Credit Agreement submitted to Issuing Bank pursuant hereto shall constitute the certification by the Company and the Account Party of the matters set forth in Section 3.2
(a) through (d) hereof. The Agent shall be entitled to rely on such certification without any duty of inquiry. 

        3.3    Notice.    The Issuing Bank will deliver to the Agent, concurrently with or promptly following its delivery of
any Letter of Credit, a true and complete copy of each Letter of Credit. Promptly upon its receipt thereof, Agent shall give notice, substantially in the form attached as Exhibit F, to each
Revolving Credit Bank of the issuance of each Letter of Credit, specifying the amount thereof and the amount of such Revolving Credit Bank's Percentage thereof. 

        3.4    Letter of Credit Fees.    The Borrowers shall pay to the Agent for distribution to the Revolving Credit Banks
in accordance with their Percentages, letter of credit fees as follows: 

        (a)  A
per annum letter of credit fee with respect to the undrawn amount of each Letter of Credit issued pursuant hereto (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). 

        (b)  A
letter of credit facing fee in the amount equal to the greater of (i) $250 or (ii) one quarter of one percent (.25%) on the face amount of each Letter of
Credit to be retained by Issuing Bank for its own account. 

        (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 Bank or any Revolving Credit Bank or (ii) impose on Issuing Bank or any Revolving Credit Bank 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 Bank or such Revolving Credit Bank 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 Bank's or such Revolving Credit Bank's reasonable allocation of the aggregate of such cost increases and expenses resulting from such events), then, upon demand by the
Issuing Bank or such Revolving Credit Bank, as the case may be, the applicable Account Party shall, within thirty (30) days following demand for payment, pay to Issuing Bank or such Revolving
Credit Bank, as the case may be, from time to time as specified by the Issuing Bank or such Revolving Credit Bank, additional amounts which shall be sufficient to compensate the Issuing Bank or such
Revolving Credit Bank 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. Each demand for payment under this Section 3.4(c), shall be accompanied by a certificate of Issuing Bank or the applicable Revolving Credit Bank (as applicable) setting forth the amount
of such increased cost or expense incurred by the Issuing Bank or such Revolving Credit Bank, as the 

35

 

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. 

        (d)  All
payments by the Borrowers to the Agent for distribution to the Issuing Bank or the Revolving Credit Banks 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 the Borrowers by the Agent. The fees described in
clauses (a) and (b) above (i) shall be nonrefundable under all circumstances, (ii) in the case of fees due under clause (a) above, shall be payable upon the issuance
of such Letter of Credit and thereafter semi-annually in advance on January 1 and July 1 of each year and (iii) in the case of fees due under clause (b) above,
shall be payable semi-annually in advance on January 1 and July 1 of each year. The fees due under clause (a) 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 any amendment or 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. 

        3.5    Other Fees.    In connection with the Letters of Credit, and in addition to the Letter of Credit Fees, the
Company and the applicable Account Party(ies) shall pay, for the sole account of the Issuing Bank, standard documentation, administration, payment and cancellation charges assessed by Issuing Bank 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 and
delivered to the relevant Account Party(ies). 

        3.6    Drawings and Demands for Payment Under Letters of Credit.    

        (a)  If
the Issuing Bank shall honor a draft or other demand for payment presented or made under any Letter of Credit, the Company and each applicable Account Party agree to
pay to the Issuing Bank an amount equal to the amount paid by the Issuing Bank in respect of such draft or other demand under such Letter of Credit and all expenses paid or incurred by the Agent
relative thereto not later than 1:00 p.m. (Detroit time), on (i) the Business Day that the Borrowers 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 the Borrowers receives such notice, if such notice is not received prior to such time. Unless the
Company or the applicable Account Party shall have made such payment to the Agent for the account of the Issuing Bank on such day, upon each such payment by the Issuing Bank, the Agent shall be deemed
to have disbursed to the Borrowers, and the Borrowers shall be deemed to have elected to substitute for the reimbursement obligation, with respect to the applicable Letters of Credit denominated in
Dollars, a Prime-based Advance of the Revolving Credit for the account of the Revolving Credit Banks in an amount equal to the amount so paid by the Issuing Bank 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 the Company or the applicable Account Party under this Section 3.6 shall be deemed
satisfied. 

        (b)  If
the Issuing Bank shall honor a draft or other demand for payment presented or made under any Letter of Credit, the Issuing Bank shall provide notice thereof to the
Company and the applicable Account Party on the date such draft or demand is honored, and to each Revolving Credit Bank on such date unless the Company or applicable Account Party shall have satisfied
its reimbursement obligation under Section 3.6(a) hereof by payment to the Agent on such date. The 

36

 

Issuing Bank shall further use reasonable efforts to provide notice to the Company or applicable Account Party prior to honoring any such draft or other demand for payment, but such notice, or the
failure to provide such notice, shall not, subject to Section 3.6(a), affect the rights or obligations of the Issuing Bank with respect to any Letter of Credit or the rights and obligations of
the parties hereto, including without limitation the obligations of the Company or applicable Account Party under Section 3.6(a) hereof. 

        (c)  Upon
issuance by the Issuing Bank of each Letter of Credit hereunder, each Revolving Credit Bank 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 Bank, 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 Agent to the Revolving Credit Banks under Section 3.6(b) hereof is not given to the Revolving Credit Banks prior to 2:00 p.m. (Detroit
time) on such date of draft or demand), shall make its Percentage of the amount paid by the Issuing Bank, and not reimbursed by the Company or applicable Account Party on such day, in immediately
available funds at the principal office of the Agent for the account of Issuing Bank. If and to the extent such Revolving Credit Bank shall not have made such pro rata portion available to the Agent,
such Revolving Credit Bank, the Company and the applicable Account Party severally agree to pay to the Issuing Bank forthwith on demand such amount together with interest thereon, for each day from
the date such amount was paid by the Issuing Bank until such amount is so made available to the Agent at a per annum rate equal to the interest rate applicable during such period to the related
Advance deemed to have been disbursed under Section 3.6(a) in respect of the reimbursement obligation of the Company and the applicable Account Party, as set forth in
Section 2.4(c)(i) or 2.4(c)(ii) hereof, as the case may be. If such Revolving Credit Bank shall pay such amount to the Agent for the account of Issuing Bank together with such
interest, if any, such amount so paid shall be deemed to constitute an Advance by such Revolving Credit Bank disbursed in respect of the reimbursement obligation of the Company or applicable Account
Party 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 Bank to make its pro
rata portion of any such amount paid by the Issuing Bank available to the Agent for the account of Issuing Bank shall not relieve any other Revolving Credit Bank of its obligation to make available
its pro rata portion of such amount, but no Revolving Credit Bank shall be responsible for failure of any other Revolving Credit Bank to make such pro rata portion available to the Agent for the
account of Issuing Bank. 

        Notwithstanding
the foregoing however no Revolving Credit Bank shall be deemed to have acquired a participation in a Letter of Credit if, prior to the issuing of the Letter of Credit by
the Issuing Bank, the Agent or the Issuing Bank had obtained actual knowledge that an Event of Default had occurred and was continuing; provided, however that the Revolving Credit Banks shall be
deemed to have acquired such a participation upon the date of which such Event of Default has been waived by the requisite Revolving Credit Banks, as applicable. 

37

  

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

        Obligations Irrevocable.    The obligations of the Company and any Account Party to make payments to Agent for the account of
Issuing Bank or the Revolving Credit Banks 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: 

        (e)  Any
lack of validity or enforceability of any Letter of Credit or any documentation relating to any Letter of Credit or to any transaction related in any way to any
Letter of Credit (the "Letter of Credit Documents"); 

        (f)    Any
amendment, modification, waiver, consent, or any substitution, exchange or release of or failure to perfect any interest in collateral or security, with 

        (g)  The
existence of any claim, setoff, defense or other right which the Company or any Account Party 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 Bank or any Revolving Credit Bank or any other person or
entity, whether in connection with any of the Letter of Credit Documents, the transactions contemplated herein or therein or any unrelated transactions; 

        (h)  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; 

        (i)    Payment
by the Issuing Bank 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; 

        (j)    Any
failure, omission, delay or lack on the part of the Agent, Issuing Bank or any Revolving Credit Bank 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 Bank, any Revolving Credit Bank 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 Bank, any Revolving Credit Bank or any such party; or 

        (k)  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 the Company
or any Account Party 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 the Company or any Account Party has or may have against the beneficiary of any Letter of
Credit shall be available hereunder to the Company or any Account Party against the Agent, Issuing Bank or any Revolving Credit Bank. Nothing contained in this Section 3.7 shall be deemed to
prevent the Company or the Account Parties, after satisfaction in full of the absolute and unconditional obligations of the Company and the Account Parties hereunder, 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 Bank or any Revolving Credit Bank. 

        3.7    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 Bank shall have the sole right to take or refrain from taking any and all actions under or upon the Letters of Credit. 

38

 

        (b)  Subject
to other terms and conditions of this Agreement, Issuing Bank 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 Bank's regularly established practices and procedures and will have no further
obligation with respect thereto. In the administration of Letters of Credit, Issuing Bank shall not be liable for any action taken or omitted on the advice of counsel, accountants, appraisers or other
experts selected by Issuing Bank with due care and Issuing Bank may rely upon any notice, communication, certificate or other statement from the Company, any Account Party, beneficiaries of Letters of
Credit, or any other Person which Issuing Bank believes to be authentic. Issuing Bank will, upon request, furnish the Revolving Credit Banks 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 Bank makes no representation and shall have no
responsibility with respect to (i) the obligations of the Company or any Account Party 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,
the Company, the applicable Account Party or any other Person, or (iii) any failure or delay in exercising any rights or powers possessed by Issuing Bank in its capacity as issuer of Letters of
Credit in the absence of its gross negligence or willful misconduct. Each of the Revolving Credit Banks expressly acknowledges that it has made and will continue to make its own evaluations of the
Company's and the Account Parties' creditworthiness without reliance on any representation of Issuing Bank or Issuing Bank's officers, agents and employees. 

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

        3.8    Indemnification.    The Company and each Account Party hereby indemnifies and agrees to hold harmless the
Revolving Credit Banks, the Issuing Bank and the Agent, and their respective officers, directors, employees and agents (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 Banks, the Issuing Bank 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 Bank, any Revolving Credit Bank 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 Bank 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 the gross negligence or willful misconduct of the Issuing 

39

 

Bank), 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; 

provided,
however, that with respect to subparagraphs (a) through (e) hereof, (i) neither the Company nor any of the Account Parties shall be required to indemnify any L/C
Indemnified Person for any L/C Indemnified Amounts to the extent such amounts result from such L/C Indemnified Person's gross negligence or willful misconduct and (ii) the Agent and the Issuing
Bank shall be liable to the Company and the Account Parties to the extent, but only to the extent, of any direct, as opposed to consequential or incidental, damages suffered by the Company and the
Account Parties which were caused by the Issuing Bank's gross negligence, or willful misconduct or by the Issuing Bank'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. 

        (f)    It
is understood that in making any payment under a Letter of Credit the Issuing Bank 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. 

        3.9    Right of Reimbursement.    Each Revolving Credit Bank agrees to reimburse the Issuing Bank 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 Bank to be reimbursed by the
Company or any Account Party pursuant to any Letter of Credit Agreement or any Letter of Credit, to the extent not reimbursed by the Company or any Account 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 Bank 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 the Company or any Account Party, except to the extent that such liabilities,
losses, costs or expenses were incurred by Issuing Bank as a result of Issuing Bank's gross negligence or willful misconduct or by the Issuing Bank'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. 

4.    TERM LOAN  

        4.1    Term Loan.    

        (a)  Term
Loan. Subject to the terms and conditions hereof, each Term Loan Bank, severally and for itself alone, agrees to make Advances of the Term Loan to the Borrowers
from time to time on any Business Day during the Term Loan Funding Period in an aggregate amount not to exceed at any one time outstanding such Bank's Percentage of the Term Loan Maximum Amount.
Advances and repayments but not readvances of the Term Loan may be made hereunder, subject to the terms and conditions of this Agreement. Upon the expiration of the Term Loan Funding Period, the
Banks' commitments to make additional Advances of the Term Loan shall expire. 

        4.2    Accrual of Interest and Maturity; Evidence of Indebtedness.    (a) The Borrowers hereby unconditionally
promise to pay to the Agent for the account of each Term Loan Bank such Bank's 

40

 

Percentage of the then unpaid aggregate principal amount of the Term Loan outstanding on the Term Loan 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, the unpaid principal Indebtedness outstanding under the Term Loan shall, from the Effective Date (until paid) bear interest
at the Applicable Interest Rate. 

        (b)  Each
Term Loan Bank shall maintain in accordance with its usual practice an account or accounts evidencing indebtedness of the Borrowers to the appropriate lending
office of such Bank resulting from each Advance of the Term Loan made by such lending office of such Bank from time to time, including the amounts of principal and interest payable thereon and paid to
such Bank from time to time under this Agreement. 

        (c)  The
Agent shall maintain the Register pursuant to Section 13.8(f), and a subaccount therein for each Term Loan Bank, in which Register and subaccounts (taken
together) shall be recorded (i) the amount of each Advance of the Term Loan made hereunder, the type thereof and each Interest Period applicable to any Eurocurrency-based Advance,
(ii) the amount of any principal or interest due and payable or to become due and payable from the Borrowers to each Term Loan Bank hereunder in respect of the Advances of the Term Loan and
(iii) both the amount of any sum received by the Agent hereunder from the Borrowers in respect of the Advances of the Term Loan and each Bank's share thereof. 

        (d)  The
entries made in the Register and the accounts of each Term Loan Bank maintained pursuant to paragraphs (b) and (c) of this Section 4.2 shall
absent manifest error, to the extent permitted by applicable law, be conclusive evidence of the existence and amounts of the obligations of the Borrowers therein recorded; provided, however, that the
failure of any Bank or the Agent to maintain the Register or any such account, as applicable, or any error therein, shall not in any manner affect the obligation of the Borrowers to repay the Advances
of each of the Term Loan (and all other amounts owing with respect thereto) made to the Borrowers by such Bank in accordance with the terms of this Agreement. 

        (e)  The
Borrowers agree that, upon written request to the Agent by any Term Loan Bank, the Borrowers will execute and deliver, to such Bank, at the Borrowers' own expense, a
Term Loan Note of the Borrowers evidencing the outstanding Advances under Term Loan owing to such Bank; provided, that the delivery of such Term Notes shall not be a condition precedent to the
Effective Date. 

        4.3    Requests for Funding Term Loan Advances.    The Borrowers may request the funding of an Advance of the Term
Loan only upon delivery to the Agent of a Request for Term Loan Advance executed by an authorized officer of the Borrowers, subject to the terms and conditions set forth in this Agreement, including
the following (confirmed by corporate resolution or similar writing delivered to Agent): 

        (a)  Each

Term Loan Maximum Amount; 

        (c)  the

41

 

        (d)  each
such Request for Advance shall be delivered to the Agent by 1:00 p.m. (Detroit time) three (3) Business Days prior to the proposed date of the Term
Loan Advance, except in the case of a Prime-based Advance, for which the Request for Advance must be delivered by 12:00 p.m. (Detroit time) on such proposed date for Advances and shall set
forth and/or include (or be accompanied by) the information required for such Request for Advance, including without limitation: 

        (i)    the
proposed date that the Term Loan Advance is to be funded which must be a Business Day during the Term Loan Funding Period; and 

        (ii)  a
Term Loan Rate Request, indicating whether such Advance is to be a Prime-based Advance or a Eurocurrency-based Advance, and, except in the case of a Prime-based
Advance, the Interest Period applicable thereto; and 

        (iii)  a
description of the type and the amount of Capital Stock to be funded or reimbursed by the Term Loan Advance requested thereby. 

        (e)  each
Request for a Term Loan Advance, once delivered to the Agent, shall not be revocable by the Borrowers and shall constitute a certification by the Borrowers as of
the date thereof that: 

        (i)    both
before and after such Term Loan Advance, the obligations of the Borrowers and Guarantors set forth in this Agreement and the other Loan Documents are valid, binding
and enforceable obligations of the Loan Parties; 

        (ii)  all
conditions to Term Loan Advances have been satisfied, and shall remain satisfied to the date of such Advance (both immediately before and after immediately giving
effect to such Advance); 

        (iii)  there
is no Default or Event of Default in existence, and none will exist upon the making of such Advance (both immediately before and after immediately giving effect
to such Advance); 

        (iv)  the
representations and warranties 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 respects as of the making of such Advance (both immediately before and immediately after giving effect to such Advance); and 

        (v)  the
execution of the Request for Advance will not violate the material terms and conditions of any material contract, agreement or other borrowing of any Borrower or
Guarantor. 

        4.4    Disbursement of Advances.    

        (a)  Upon
receiving any Request for Term Loan Advance from the Borrowers under Section 4.3 hereof, Agent shall promptly notify each Bank by wire, telex, facsimile or
telephone (confirmed by wire, facsimile or telex) of the amount of such Advance to be made and the date such Advance is to be made by said Bank pursuant to its Percentage of such Advance. Unless such
Bank's commitment to make Advances of the Term Loan hereunder shall have been suspended or terminated in accordance with this Agreement, each such Bank shall make available the amount of its
Percentage of each Advance in immediately available funds to Agent, as follows: 

        (i)    for
Domestic Advances, at the office of Agent located at One Detroit Center, Detroit, Michigan 48226, not later than 3:00 p.m. (Detroit time) on the date of such
Advance; and 

42

 

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

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

        (i)    for
Domestic Advances, not later than 4:00 p.m. (Detroit time) on the date of such Advance by credit to an account of the Borrowers maintained with Agent or to
such other account or third party as the Borrowers may reasonably direct; and 

        (ii)  for
Eurocurrency-based Advances, not later than 4:00 p.m. (the time of the Agent's Correspondent) on the date of such Advance, by credit to an account of the
Borrowers maintained with Agent's Correspondent or to such other account or third party as the Borrowers may reasonably direct. 

        (c)  Agent
shall deliver the documents and papers received by it for the account of each Bank to such Bank or upon its order. Unless Agent shall have been notified by any
Bank prior to the date of any proposed Term Loan Advance that such Bank does not intend to make available to Agent such Bank's Percentage of such Advance, Agent may assume that such Bank has made such
amount available to Agent on such date, as aforesaid and may, in reliance upon such assumption, make available to the Borrowers a corresponding amount. If such amount is not in fact made available to
Agent by such Bank, as aforesaid, Agent shall be entitled to recover such amount on demand from such Bank. If such Bank does not pay such amount forthwith upon Agent's demand therefor, the Agent shall
promptly notify the Borrowers and the Borrowers shall pay such amount to Agent, if such notice delivered to the Borrowers 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, provided that any such payment by the Borrowers shall not relieve a Defaulting Bank of its obligation to fund hereunder. Agent shall also be
entitled to recover from such Bank or the Borrowers, 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 the Borrowers, to the date such amount is recovered by Agent, at a rate per annum equal to: 

        (i)    in
the case of such Bank, for the first two (2) Business Days such amount remains unpaid, with respect to Domestic Advances, the Federal Funds Effective Rate, and
with respect to Eurocurrency-based Advances, Agent's aggregate marginal cost (including the cost of maintaining any required
reserves or deposit insurance and of any fees, penalties, overdraft charges or other costs or expenses incurred by Agent as a result of such failure to deliver funds hereunder) of carrying such amount
and thereafter, at the rate of interest then applicable to such Term Loan Advances; and 

        (ii)  in
the case of the Borrowers, the rate of interest then applicable to such Advance of the Term Loan. 

        The
obligation of any Bank to make any Advance of the Term Loan hereunder shall not be affected by the failure of any other Bank to make any Advance hereunder, and no Bank shall have any
liability to the Company or any of its Subsidiaries, the Agent, any other Bank, or any other party for another Bank's failure to make any loan or Advance hereunder. In the event any Bank shall fail to
advance any amounts required to be advanced in accordance with the terms of this Article 4 (a "Defaulting Bank"), the Agent shall promptly provide written notice thereof to the Borrowers and to
each other Bank (each such other Bank being referred to in this Section as a "Non-Defaulting Bank"). Each Non-Defaulting Bank shall have ten (10) Business Days from
receipt of said notice to exercise its 

43

 

option to agree to enter into an agreement pursuant to which the Non-Defaulting Bank shall assume the Defaulting Bank's rights and obligations under this Agreement, its Notes and the
other Loan Documents. The Non-Defaulting Bank shall exercise such option by providing written notice of same to the Defaulting Bank (and if there is more than one
Non-Defaulting Bank, the assignment agreement shall be entered into with the Non-Defaulting Bank who first notifies the Defaulting Bank of its decision to exercise said option)
and to the Borrowers. If no Non-Defaulting Bank shall exercise the above-described option within the said ten (10) Business Day period and if the Borrowers shall, subject to
Section 13.8(c) hereof, within thirty (30) days of delivering the notice described above, advise such Defaulting Bank of another bank or financial institution to which assignments are
permitted pursuant to Section 13.8(c) hereof and which is willing to assume such Defaulting Bank's rights and obligations under this Agreement, its Notes and the other Loan Documents (each such
bank or financial institution being hereinafter referred to as a "Potential Financial Institution"), such Defaulting Bank shall, subject to Section 13.8(c), assign its said rights and
obligations to the Potential Financial Institution; provided however that any such assignment shall not alter the Borrowers' remedies vis a vis the Defaulting Bank. 

        4.5    Repayment of Principal.    The Borrowers shall repay Term Loan in quarterly principal installments on the first
day of each calendar quarter during the periods set forth below, commencing with the quarter beginning in accordance with the following schedule, until the Term Loan Maturity Date, when all principal
plus accrued interest thereon shall be due and payable:

        4.6    Term Loan Rate Requests; Refundings and Conversions of Advances of Term Loan.    On the Effective Date the
Applicable Interest Rate for the Term Loan shall be the Prime-based Rate. Thereafter the Borrowers may refund all or any portion of any Advance of the Term Loan as an Advance with a like Interest
Period or convert each such Advance of the Term Loan to an Advance with a different Interest Period, but only after delivery to Agent of a Term Loan Rate Request 

44

 

executed in connection with the Term Loan by an authorized officer of the Borrowers and subject to the terms hereof and to the following: 

        (a)  each
such Term Loan Rate Request shall set forth the information required on the Term Loan Rate Request form attached hereto as Exhibit P with respect to the Term
Loan, including without limitation: 

        (i)    whether
such Request is delivered in connection with the Term Loan; 

        (ii)  whether
the Advance is a refunding or conversion of an outstanding Advance; 

        (iii)  in
the case of a refunding or conversion of an outstanding Advance, the proposed date of such refunding or conversion, which must be a Business Day; and 

        (iv)  whether
such Advance (or any portion thereof) is to be a Prime-based Advance or a Eurocurrency-based Advance, and, except in the case of a Prime-based Advance, the
Interest Period(s) applicable thereto. 

        (b)  each
such Term Loan Rate Request shall be delivered to Agent by 1:00 p.m. (Detroit time) three (3) Business Days prior to the proposed date of Advance,
except in the case of a Prime-based Advance, for which the Term Loan Rate Request must be delivered by 1:00 p.m. (Detroit time) on the proposed date of Advance; 

        (c)  the
principal amount of such Advance of the Term Loan plus the amount of any other Advance of the Term Loan to be then combined therewith having the same Applicable
Interest Rate and Interest Period, if any, shall be (i) in the case of a Prime-based Advance at least Seven Hundred Fifty Thousand ($750,000), or the remaining principal balance outstanding
under the Term Loan, whichever is less, and (ii) in the case of a Eurocurrency-based Advance at least One Million Dollars ($1,000,000) or the remaining principal balance outstanding under the
Term Loan, whichever is less, or in each case a larger integral multiple of One Hundred Thousand Dollars ($100,000); 

        (d)  no
Advance shall have an Interest Period ending after the Term Loan Maturity Date and, notwithstanding any provision hereof to the contrary, the Borrowers shall select
Interest Periods (or the Prime-based Rate) for sufficient portions of the Term Loan such that the Company may make the required principal payments hereunder on a timely basis and otherwise in
accordance with Section 4.5 hereof; 

        (e)  upon
completion of the Advance there shall be no more than five (5) Interest Periods in effect for Advances of Term Loan; and 

        (f)    a
Term Loan Rate Request, once delivered to Agent, shall not be revocable by the Borrowers. 

Each
selection of an Interest Period under this Section 4.6, and the amount and date of any repayment, shall be noted on Agent's records, which records will be conclusive evidence thereof,
absent manifest error. 

        4.7    Prime-based Advance in Absence of Election or Upon Default.    In the event the Borrowers shall fail with
respect to any Eurocurrency-based Advance of the Term Loan to timely exercise its option to refund or convert such Advance in accordance with Section 4.6 hereof (and such Advance has not been
paid in full on the last day of the Interest Period applicable thereto according to the terms hereof), or, subject to Section 4.9 hereof, if on the last day of the applicable Interest Period, a
Default or Event of Default shall exist, then, on the last day of the applicable Interest Period, the principal amount of such Advance which has not been prepaid shall be automatically converted to a
Prime-based Advance and the Agent shall thereafter promptly notify the Borrowers thereof. 

45

 

        4.8    Prime-based Interest Payments.    Interest on the unpaid principal of all Prime-based Advances of the Term Loan
from time to time outstanding shall accrue until paid at a per annum interest rate equal to the Prime-based Rate, and shall be payable in immediately available funds quarterly commencing on the first
day of the calendar quarter next succeeding the fiscal quarter during which the initial Advance of the Term Loan is made and on the first day of each calendar quarter thereafter. 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. 

        4.9    Eurocurrency-based Interest Payments.    Interest on the unpaid principal of each Eurocurrency-based Advance of
the Term Loan having a related Eurocurrency-Interest Period of 3 months or less shall accrue at its Eurocurrency-based Rate and shall be payable in immediately available funds on the last day
of the Interest Period applicable thereto. Interest shall be payable in immediately available funds on each Eurocurrency-based Advance of the Term Loan outstanding from time to time having a
Eurocurrency-Interest Period of 6 months or longer, at intervals of 3 months after the first day of the applicable Interest Period, and shall also be payable on the last day of the
Interest Period applicable thereto. Interest accruing at the Eurocurrency-based 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. 

        4.10    Interest Payments on Conversions.    Notwithstanding anything to the contrary in Sections 4.8 and 4.9, all
accrued and unpaid interest on any Advance refunded or converted pursuant to Section 4.6 hereof, except for any conversions or refundings of Prime-based Advances, shall be due and payable in
full on the date such Advance is refunded or converted. 

        4.11    Interest on Default.    Notwithstanding anything to the contrary set forth in Sections 4.8 and 4.9, in the
event and so long as any Event of Default shall exist, in the case of any Event of Default under Sections 9.1(a) or 9.1(j), immediately upon the occurrence thereof, and in the case of all other Events
of Default, upon notice from the Majority Term Loan Banks, interest shall be payable on demand on the principal amount of all Advances of the Term Loan from time to time outstanding (and, to the
extent delinquent, on all other monetary obligations of the Borrowers hereunder and under the other Loan Documents) at a per annum rate equal to the Applicable Interest Rate in respect of each such
Advance, plus, in the case of Eurocurrency-based Advances, two percent (2%) per annum for the remainder of the then existing Interest Period, if any, and at all other such times and for all Prime-
based Advances, at a per annum rate equal to the Prime-based Rate, plus two percent (2%). 

        4.12    Optional Prepayment of Term Loan.    

        (a)  Subject
to this Section 4.10, at its option the Borrowers may prepay all or any portion of the outstanding principal of the Term Loan bearing interest at the
Prime-based Rate or upon one (1) Business Day's notice to the Agent by wire, facsimile, telex or by telephone (confirmed by wire, facsimile or telex), bearing interest at the Eurocurrency-based
Rate, at any time and from time to time, with accrued interest on the principal being prepaid to the date of such prepayment. Any prepayment of a portion of the Term Loan as to which the Applicable
Interest Rate is the Prime-based Rate shall be without premium or penalty. Any other prepayment shall be subject to the provisions of Section 11.1. 

        (b)  Each
optional partial prepayment of the Term Loan shall be applied pro rata to reduce all subsequent principal installments due thereunder. 

All
prepayments of the Term Loan shall be made to the Agent for distribution ratably to the applicable Banks in accordance with their respective Percentages. 

46

 

        4.13    Mandatory Prepayment of Term Loan.    

        (a)  So
long as the Consolidated Funded Debt to EBITDA ratio is more than 0.5 to 1.0 as of any quarter end during the applicable fiscal year, the Term Loan shall be subject
to required principal reductions in the amount of fifty percent (50%) of Excess Cash Flow, payable in respect of each fiscal year beginning with the fiscal year ending from and including the fiscal
year ending December 31, 2002 and each fiscal year thereafter through the applicable Term Loan Maturity Date, on the earlier of (i) date of the Borrowers delivery of the annual financial
statements pursuant to Section 7.1(a) hereof for each such fiscal year and (ii) March 31 of the year following the applicable fiscal year, provided that no such prepayment shall
be required if the amount of such prepayment would be less than $50,000. 

        (b)  Subject
to clause (e) hereof, immediately upon receipt by the Company or any Subsidiary of any Net Cash Proceeds from Asset Sales, the Borrowers shall prepay the
Term Loans by an amount equal to one hundred percent (100%) of such Net Cash Proceeds until the Term Loan has been paid in full, provided that no such prepayment shall be required if the amount of
such prepayment resulting from any transaction or related series of transactions would be less than $50,000. 

        (c)  Subject
to clause (e) hereof, immediately upon receipt by the Company or any Subsidiary of Net Cash Proceeds from the issuance of any Equity Interests of such
Person other than Equity Interests under the stock option or employee incentive plans listed on Schedule 6.23 hereto (or any successor plans) or pursuant to any option or warrant originally
issued to employees under such plans or pursuant to those options or warrants issued in connection with prior acquisitions and described on Schedule 2.13/4.13 hereto, or from the issuance of
any Subordinated Debt, other than Funded Debt (which is Subordinated Debt) permitted under Section 8.1(c) or (j) hereof or which does not yield cash proceeds to the Company or a
Subsidiary, issued after the Effective Date by such Person, the Borrowers shall be obligated to repay the Term Loan by an amount equal to (y) fifty percent (50%) of such cash proceeds in the
case of any such issuance of Equity Interests or (z) one hundred percent (100%) of such cash proceeds in the case of any such issuance of Subordinated Debt (net, in any case, of reasonable and
customary costs and expenses of issuance), provided, however, that to the extent that the amount of the cash proceeds described in (y) and (z) above, as applicable, exceeds the
outstanding Indebtedness under the Term Loan, the remainder shall be subject to Section 2.13(b) hereof; provided that no such prepayment shall be required if the amount of such prepayment
resulting from any transaction or related series of transactions would be less than $50,000. 

        (d)  Subject
to clause (e) hereof, mandatory prepayments under this Section 4.13 shall be in addition to any scheduled installments or optional prepayments made
prior thereto and shall be subject to Section 11.1. Each mandatory prepayment of the Term Loan under Section 4.13(a) and (c) shall be applied to the principal payments of the Term
Loan due thereunder in the inverse order of their maturities. Each mandatory prepayment of the Term Loan made pursuant to this Section 4.13(b) shall be applied pro rata to reduce all subsequent
principal installments due thereunder. 

47

  

        (e)  To
the extent that, on the date any mandatory prepayment of the Term Loan under this Section 4.13 is due, the Indebtedness under the Term Loan or any other
Indebtedness to be prepaid is being carried, in whole or in part, at the Eurocurrency-based Rate and no Default or Event of Default has occurred and is continuing, the Borrowers 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 Banks (which shall be an interest-bearing account), on such terms and conditions as are
reasonably acceptable to Agent and upon such deposit, the obligation of the Borrowers 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 Term Loan on the last day of each Interest Period
attributable to the Eurocurrency-based Advances of the Term Loan, thereby avoiding breakage costs under Section 11.1. All prepayments of the Term Loan hereunder shall be made to the Agent for
distribution ratably to the Term Loan Banks. 

        4.14    Term Loan Commitment Fee.    From the Effective Date to (but excluding) the last day of the Term Loan Funding
Period, the Borrowers shall pay to each of the Term Loan Banks, a Term Loan Commitment Fee determined by multiplying the Applicable Fee Percentage times the average daily amount by which such Bank's
Percentage of the Term Loan Maximum Amount then in effect exceeds the sum of such Bank's Percentage of the aggregate principal amount of Term Loan Advances outstanding from time to time during such
period, calculated on a daily basis. The Term Loan Commitment Fee shall be payable quarterly in arrears on July 1, 2002 and on October 1, 2002, and at the termination of the Term Loan
Funding Period, and shall be computed on the basis of a year of three hundred sixty (360) days and assessed for the actual number of days elapsed. Whenever any payment of the Term Loan
Commitment 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. Such Term Loan Commitment Fee shall be paid by the Borrowers
to the Agent. Upon receipt of such payment, Agent shall make prompt payment to each Bank of its share of the Term Loan Commitment Fee. The Term Loan Commitment Fee shall not be refundable under any
circumstance. 

        4.15    Use of Proceeds.    Proceeds of the Term Loan shall be used by the Borrowers to finance the MDI Acquisition,
the MDI Tender Offer and the MDI Merger, and related transactions, including the acquisition of other Capital Stock of Mechanical Dynamics.

Subsidiaries to a tax or penalty imposed by Section 4975 of the Code or Section 502(i) of ERISA in an amount that would be material. All Pension Plans are in material compliance

of any Hazardous Material Law, or 

        (ii)  written
complaints, notices or inquiries to any Loan Party or any of their respective Subsidiaries regarding potential liability of the Loan Parties or any of their
respective subsidiaries under any Hazardous Material Law; and 

        (c)  to
the best knowledge of the Borrowers, no conditions exist at, on or under any property now or previously owned or leased by the Loan Parties or any of their respective
Subsidiaries 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

forma financial information
furnished to Agent and the Banks prior to the Effective Date are based upon good faith estimates and assumptions believed by management of the Company to be reasonable at the time made, it being
recognized by the Banks 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)  Since

Company and its Subsidiaries will each be solvent, able to pay its indebtedness as it matures and will have capital sufficient to carry on its business and all business in which it is about to engage.
This Agreement is being executed and delivered by the Borrowers to Agent and the Banks in good faith and in exchange for fair, equivalent consideration. Neither the Company nor any Subsidiary intends
to nor does management of the Company or any Subsidiary believe it will incur debts beyond its ability to pay as they mature. Neither the Company nor any Subsidiary contemplates 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 the Company or any Subsidiary, nor does the
Company or any Subsidiary have any knowledge of any threatened bankruptcy or insolvency proceedings against the Company or any Subsidiary.

        9.4    Waiver by Borrowers of Certain Laws.    To the extent permitted by applicable law, the Borrowers hereby agrees

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 Banks 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 Banks. 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
Banks in enforcing any of their rights shall constitute a waiver of any of their rights. Each Borrower expressly agrees that this Section may be waived or modified only in accordance with
Section 13.10 and may not be waived or modified by the Banks 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 Bank may at any time
and from time to time, without notice to the Borrowers but subject to the provisions of Section 10.3 hereof (any requirement for such notice being expressly waived by the Borrowers), setoff and
apply against any and all of the obligations of the Borrowers now or hereafter existing under this Agreement, whether owing to such Bank, any Affiliate of such Bank or any other Bank 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 Bank to or for the credit or the account of any Borrower
and any property of any Borrower from time to time in possession of such Bank, irrespective of
whether or not such deposits held or indebtedness owing by such Bank may be contingent and unmatured and regardless of whether any Collateral then held by Agent or any Bank is adequate to cover the
Indebtedness. Promptly following any such setoff, such Bank shall give written notice to Agent and to Borrowers of the occurrence thereof. The Borrowers hereby grants to the Banks and the Agent a lien
on and security interest in all such deposits, indebtedness and property as collateral security for the payment and performance of all of the obligations of the Company under this Agreement. The
rights of each Bank under this Section 9.6 are in addition to the other rights and remedies (including, without limitation, other rights of setoff) which such Bank may have. 

10.  PAYMENTS, RECOVERIES AND COLLECTIONS; MARGIN ADJUSTMENTS  

        10.1    Payment Procedure.    

        (a)  Except
as otherwise provided herein, all payments by the Borrowers in respect of principal of, or interest on, any Advance in Dollars under the Revolving Credit or under
the Term Loan or in respect of any Letter of Credit Obligations under the Revolving Credit or Fees hereunder which are payable in Dollars shall be made without setoff or counterclaim on the date
specified for payment under this Agreement not later than 1:00 p.m. (Detroit time) in Dollars in immediately available funds to Agent, for the ratable account of the Revolving Credit Banks in
the case of payments in respect of the Revolving Credit, the ratable benefit of the Term Loan Banks in the case of payments in respect of the Term Loan, at Agent's office located at One Detroit
Center, 

74

 

Detroit, Michigan 48226-3289. Upon receipt of each such payment, the Agent shall make prompt payment to each applicable Bank, or, in respect of Eurocurrency-based Advances, such Bank's
Eurocurrency Lending Office, in like funds and currencies, of all amounts received by it for the account of such Bank. 

        (b)  Unless
the Agent shall have been notified by the Borrowers prior to the date on which any payment to be made by the Borrowers is due that the Borrowers do not intend to
remit such payment, the Agent may, in its sole discretion and without obligation to do so, assume that the Borrowers have remitted such payment when so due and the Agent may, in reliance upon such
assumption, make available to each Revolving Credit Bank, Term Loan Bank, as the case may be, on such payment date an amount equal to such Bank's share of such assumed payment. If Company has not in
fact remitted such payment to the Agent each Revolving Credit Bank shall forthwith on demand repay to the Agent the amount of such assumed payment made available or transferred to such Bank, 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 Bank to the date such amount is repaid to the Agent at a rate per
annum equal to (i) for Prime-based Advances, the Federal Funds Effective Rate (daily average), as the same may vary from time to time, and (ii) with respect to Eurocurrency-based
Advances or Quoted Rate Advances, Agent's aggregate marginal cost (including the cost of maintaining any required reserves or deposit
insurance and of any fees, penalties, overdraft charges or other costs or expenses incurred by Agent) of carrying such amount. 

        (c)  Subject
to the definition of Interest Period, 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 the Borrowers under this Agreement or any of the Notes (including without limitation payments under the Swing Line) shall be made without
setoff or counterclaim, as aforesaid, and, subject to full compliance by each Bank (and each assignee and participant pursuant to Section 13.8) with Section 13.12, 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 net income, net profits or franchise taxes imposed on the Agent or any Bank as a result of a present or former
connection between the Agent or such Bank and the governmental authority, political subdivision, federation or organization imposing such taxes), unless the Borrowers are compelled by law to make
payment subject to such tax. In such event, the Borrowers shall: 

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

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

As
used herein, the terms "tax", "taxes" and "taxation" include all taxes (other than taxes on or measured by the overall income of a Person), levies, imposts, duties, charges, fees, deductions and
withholdings and any restrictions or conditions resulting in a charge together with interest (and any taxes payable upon the amounts paid or payable pursuant to this Section 10.1) thereon, or
the payment 

75

 

or delivery of funds into or out of any jurisdiction other than the United States (whether assessed against any of the Borrowers, Agent or any of the Banks). The Borrowers shall be reimbursed by the
applicable Bank for any payment made by the Borrowers under this Section 10.1 if the applicable Bank is not in compliance with its obligations under Section 13.12. 

        10.2    Application of Proceeds of Collateral.    Notwithstanding anything to the contrary in this Agreement, after an
Event of Default and the exercise of remedies pursuant to Article 9 of this Agreement or the other Loan Documents, the proceeds of any Collateral, together with any offsets, voluntary payments
by Company or any Subsidiary of the Company or others and any other sums received or collected in respect of the Indebtedness, shall be applied, first, to the Indebtedness under the Revolving Credit
(including the Swing Line) and the Term Loans and any Reimbursement Obligations on a pro rata basis (or in such order and manner as determined by the Majority Banks, the Majority Revolving Credit
Banks and the Majority Term Loan Banks; subject, however, to the applicable Percentages of the loans held by each of the Banks), next, to any other Indebtedness on a pro rata basis, and then, if there
is any excess, to Company and the Subsidiaries, as the case may be. Subject to the terms of this Section 10.2, the application of such proceeds and other sums to the Advances of the Revolving
Credit and the Term Loans, the Reimbursement Obligations and under any Bank Hedging Agreements shall be based on each Bank's Weighted Percentage of the aggregate of the loans. 

        10.3    Pro-rata Recovery.    If any Bank 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 Indebtedness in excess of its pro rata share of payments then or thereafter obtained by all
Banks upon principal of and interest on all Indebtedness, such Bank shall purchase from the other Banks such participations in the Revolving Credit and/or the Term Loans, and/or Reimbursement
Obligation held by them as shall be necessary to cause such purchasing Bank to share the excess payment or other recovery ratably with the Percentage with each of them in accordance with the
applicable Percentages of the Banks; 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. 

        10.4    Margin Adjustments.    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 and the Applicable Fee Percentage, 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, in each case with no retroactivity or claw-back. In the event the Company fails 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 delivered, the margins and fee percentages shall be at the next higher level (if any) 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) under Section 7.1(b) of the Company's financial statements for the fiscal
quarter ending September 30, 2002, the margins and fee percentages shall be those set forth under the Level II column of the Pricing Matrix attached to this Agreement as Schedule 1.1.
Thereafter, all margins and fee percentages shall be based upon the Company's quarterly financial statements and Covenant Compliance Reports, subject to recalculation as provided in Subsection 10.4(a)
above.

11.  CHANGES IN LAW OR CIRCUMSTANCES; INCREASED COSTS  

        11.1    Reimbursement of Prepayment Costs.    If the Borrowers make any payment of principal with respect to any
Eurocurrency-based Advance or Quoted Rate Advance on any day other than the last day of the Interest Period applicable thereto (whether voluntarily, by acceleration, or otherwise), or if the Borrowers
convert or refund (or attempts to convert or refund) any such Advance on any day other than the last day of the Interest Period applicable thereto; or if the Borrowers fail to borrow, refund or
convert into any Eurocurrency-based Advance or Quoted Rate Advance after notice has been given by the Borrowers to Agent in accordance with the terms hereof requesting such Advance, or if the
Borrowers fail to make any payment of principal or interest in respect of a Eurocurrency-based Advance or Quoted Rate Advance when due, the Borrowers shall reimburse Agent for itself and/or on behalf
of any Bank, 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 Banks, 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 Banks, as the case may be, shall have funded or committed to fund such Advance. Such amount payable by the Borrowers to Agent for itself and/or on behalf of any Bank,
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 Banks, as the case may be) which would have accrued to Agent and Banks,
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 Bank
under this paragraph shall be made as though such Bank 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 Bank may fund any Eurocurrency-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 the written request of the
Borrowers, Agent and Banks shall deliver to the Borrowers a certificate setting forth the basis for determining such losses, costs and expenses, which certificate shall be conclusively presumed
correct, absent manifest error. 

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

        11.3    Circumstances Affecting Eurocurrency-based Rate Availability.    If with respect to any Interest Period, Agent
or the Majority Banks (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 Banks for such Interest Period, then Agent shall forthwith give notice thereof to the Borrowers. Thereafter, until
Agent notifies the Borrowers that such circumstances no longer exist, (i) the obligation of Banks to make Eurocurrency-based Advances, and the right of the Borrowers to convert an Advance to or
refund an Advance as a Eurocurrency-based Advance, as the case may be, shall be suspended, and (ii) effective upon the last day of each Interest Period related to any existing
Eurocurrency-based Advance, such Eurocurrency-based Advance shall automatically be converted into a Prime-based Advance (without regard to satisfaction of any conditions to conversion contained
elsewhere herein). 

77

 

        11.4    Laws Affecting Eurocurrency-based Advance Availability.    If, after the date of this Agreement, the
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 Banks (or any of their respective Eurocurrency 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 Banks (or any of their respective Eurocurrency Lending Offices) to honor its obligations hereunder to make or maintain any Advance with
interest at the Eurocurrency-based Rate, such Bank shall forthwith give notice thereof to the Borrowers and to Agent. Thereafter, (a) the obligations of the applicable Banks to make
Eurocurrency-based Advances and the right of the Borrowers to convert an Advance into or refund an Advance as a Eurocurrency-based Advance shall be suspended and thereafter the Borrowers 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 Banks may not lawfully continue to maintain an Advance to the
end of the then current Interest Period applicable thereto as a Eurocurrency-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 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 Eurocurrency-based Advances.    If the adoption after the date of this Agreement of, or any
change after the date of this Agreement in, any applicable law, rule or regulation of 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 Agent or any of the Banks (or any of their respective Eurocurrency Lending Offices) with any request or directive
(whether
or not having the force of law) made by any such authority, central bank or comparable agency after the date hereof: 

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

and
the result of any of the foregoing is to increase the costs to any of the Banks of maintaining any part of the Indebtedness hereunder as a Eurocurrency-based Advance or to reduce the amount of any
sum received or receivable by any of the Banks under this Agreement in respect of a Eurocurrency-based Advance, with respect to Advances to the Borrowers, then such Bank shall promptly notify Agent,
and Agent (or such Bank, as aforesaid) shall promptly notify the Borrowers of such fact and demand compensation therefor in writing and, within fifteen (15) days after such notice, the
Borrowers agree to pay to such Bank such additional amount or amounts as will compensate such Revolving Credit Bank or Banks for such increased cost or reduction. Agent will promptly notify the
Borrowers of any event of which it has knowledge which will entitle Revolving Credit Banks to compensation pursuant to this Section, or which will cause the Borrowers to incur additional liability
under Article 11 

78

 

hereof, provided that Agent shall incur no liability whatsoever to the Banks or the Borrowers in the event it fails to do so. A certificate of Agent (or such Bank, if applicable) setting forth in
reasonable detail the basis for determining such additional amount or amounts necessary to compensate such Bank or Banks shall accompany such written demand and shall be prepared in good faith and
conclusively presumed to be correct save for manifest error. 

        11.6    Capital Adequacy and Other Increased Costs.    In the event that after the Effective Date the adoption 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 Bank or Agent, or any
interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof, or compliance by any Bank 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
Bank or Agent (or any corporation controlling such Bank or Agent) and such Bank or Agent, as the case may be, determines that the amount of such capital is increased by or based upon the existence of
such Bank's or Agent's obligations or Advances hereunder and such increase has the effect of reducing the rate of return on
such Bank'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 Bank 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 Bank or Agent to be material
(collectively, "Increased Costs"), then Agent or such Bank shall notify the Borrowers in writing, and thereafter the Borrowers shall pay to such Bank or Agent, as the case may be, within fifteen
(15) days of written demand therefor from such Bank or Agent, additional amounts sufficient to compensate such Bank or Agent (or such controlling corporation) for any increase in the amount of
capital and reduced rate of return which such Bank or Agent reasonably determines to be allocable to the existence of such Bank's or Agent's obligations or Advances hereunder; notwithstanding the
forgoing, however, the Borrowers shall not be required to pay any increased costs under this Section 11.6 or under Sections 11.3, 11.5 or 3.4(c) for any period ending prior to the date that is
ninety (90) days prior to the making of a Bank'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 ninety (90) days prior to the date of such request, in which case a Bank's request for such additional amounts relating to the period more than 90 days
prior to the making of the request must be given not more than ninety (90) days after such Bank becomes aware of the applicable change in law or other event resulting in such increased costs. 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
Bank or Agent, as the case may be, shall be submitted by such Bank or by Agent to the Borrowers, reasonably promptly after becoming aware of any event described in this Section 11.6 and shall
be conclusive, absent manifest error in computation. 

        11.7    Substitution of Banks.    If (a) the obligation of any Bank to make Eurocurrency-based Advances has
been suspended pursuant to Section 11.3 or 11.4 or (b) any Bank has demanded compensation under Section 3.4(c), 11.1 or 11.5, (in each case, an "Affected Bank"), then the
Borrowers shall have the right (subject to Section 13.8 hereof), with the assistance of the Agent, to seek a substitute Bank or Banks (which may be one or more of the Banks (the "Purchasing
Bank" or "Purchasing Banks") to purchase the Advances of the Revolving Credit, Swing Line and/or the applicable Term Loan, as the case may be and assume the commitments (including without limitation
its participations in Swing Line Advances and Letters of Credit) under this Agreement of such Affected Bank. The Affected Bank shall be obligated to sell its Advances of the Revolving Credit, Swing
Line and/or the applicable Term Loan, as the case may be, and assign its commitments to such Purchasing Bank or Purchasing Banks within fifteen days after receiving notice from the Borrowers requiring
it to do so, at an aggregate price equal to the outstanding principal amount thereof, plus unpaid interest 

79

 

accrued thereon up to but excluding the date of the sale. In connection with any such sale, and as a condition thereof, the Borrowers shall pay to the Affected Bank all fees accrued for its account
hereunder to but excluding the date of such sale, plus, if demanded by the Affected Bank within ten Business Days after such sale, (i) the amount of any compensation which would be due to the
Affected Bank under Section 11.1 if the Borrowers had prepaid the outstanding Eurocurrency-based Advances of the Affected Bank on the date of such sale and (ii) any additional
compensation accrued for its account under Sections 3.4(c) and 11.5 to but excluding said date. Upon such sale, the Purchasing Bank or Purchasing Banks shall assume the Affected Bank's commitment, and
the Affected Bank shall be released from its obligations hereunder to a corresponding extent. If any Purchasing Bank is not already one of the Banks, the Affected Bank, as assignor, such Purchasing
Bank, as assignee, Borrowers and the Agent, shall enter into an Assignment Agreement pursuant to Section 13.8 hereof, whereupon such Purchasing Bank shall be a Bank party to this Agreement,
shall be deemed to be an assignee hereunder and shall have all the rights and obligations of a Bank with a Revolving Credit Percentage equal to its ratable share of the then applicable Revolving
Credit Aggregate Commitment and the
applicable Percentages of the Term Loans of the Affected Bank. In connection with any assignment pursuant to this Section 11.7, the Borrowers or the Purchasing Bank shall pay to the Agent the
administrative fee for processing such assignment referred to in Section 13.8. 

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

12.  AGENT  

        12.1    Appointment of Agent.    Each Bank and the holder of each Note (if issued) irrevocably appoints and authorizes
the Agent to act as administrative agent on behalf of such Bank 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 solely as agent of the Banks and does not assume and
shall not be deemed to have assumed any obligation towards or relationship of agency or trust with or for the Borrowers. Each Bank agrees (which agreement shall survive any termination of this
Agreement) to reimburse Agent for all reasonable out-of-pocket expenses (including house and outside attorneys' fees and disbursements) incurred by Agent hereunder or in
connection herewith or with an Event of Default or in enforcing the obligations of the Borrowers under this Agreement or the other Loan Documents or any other instrument executed pursuant hereto, and
for which Agent is not reimbursed by the Borrowers, pro rata according to such Bank's Weighted Percentage, but excluding any such expense resulting from Agent's gross negligence or wilful misconduct.
Any such amounts so paid by the Banks shall constitute additional Indebtedness hereunder. Agent shall not be required to take any action under the Loan Documents, or to prosecute or defend any suit in
respect of the Loan Documents, unless indemnified to its satisfaction by the Banks against loss, costs, liability and expense (excluding liability resulting from its gross negligence or wilful
misconduct). If any indemnity furnished to Agent shall become impaired, it may call for additional indemnity and cease to do the acts indemnified against until such additional indemnity is given. 

        12.2    Deposit Account with Agent.    The Borrowers hereby authorizes Agent, in Agent's sole discretion, upon notice
to the Borrowers to charge its general deposit account(s), if any, maintained with Agent 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. 

80

 

        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 Bank (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 Bank 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 Banks (or all of the Banks for those acts
requiring consent of all of the Banks) (except for its or their own wilful 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 Company, or any Subsidiary or Affiliate of the Company, 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 Borrowers of their respective
obligations hereunder or thereunder, or (d) the satisfaction of any condition hereunder or thereunder, including without limitation 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 (who may be counsel for the Borrowers), independent public accountants and other experts selected by it and shall not be liable to the Banks (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 30 days prior notice to the
Borrowers and all Banks; Agent may be removed by the Majority Banks upon not less than 30 days prior written notice to the Borrowers, the Banks and Agent, but only upon (i) Agent's gross
negligence or willful misconduct or (ii) Agent's intentional failure to comply with the terms and conditions of this Agreement after receiving contrary instructions from the requisite Banks. If
Agent at any time shall resign or if the office of Agent shall become vacant for any other reason, Majority Banks shall, by written instrument, appoint successor agent(s) satisfactory to such Majority
Banks, and, so long as no Default or Event of Default has occurred and is continuing, to the Borrowers. Such successor agent shall thereupon become the Agent hereunder, as applicable, and shall be
entitled to receive from the prior Agent such documents of transfer and assignment as such successor Agent may reasonably request. Any such successor Agent shall be a commercial bank organized under
the laws of the United States or any state thereof and shall have a combined capital and surplus of at least $500,000,000. If a successor 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 Banks and, if applicable, the Borrowers, is
made and accepted or if no such temporary successor is appointed as provided above by the resigning Agent, the Majority Banks shall thereafter perform all of the duties of the resigning Agent
hereunder until such appointment by the Majority Banks and, if applicable, the Borrowers 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. 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 wilful 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. 

81

   
        12.5    Credit Decisions.    Each Bank acknowledges that it has, independently of Agent and each other Bank and
based
on the financial statements of Company 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 Bank also acknowledges that it will, independently of Agent and each other Bank 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 or any document executed pursuant hereto. 

        12.6    Authority of Agent to Enforce This Agreement.    Each Bank, subject to the terms and conditions of this
Agreement, authorizes the Agent with 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 Banks allowed in any
proceeding relative to Company, or any of its Subsidiaries, 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 Banks agree to indemnify the Agent and its Affiliates (to the extent not
reimbursed by the Borrowers, but without limiting any obligation of the Borrowers to make such reimbursement), ratably according to their respective 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 disbursements of 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 no Bank shall be liable for any portion of such claims, damages, losses, liabilities,
costs or expenses resulting from the Agent's or its Affiliates's gross negligence or willful misconduct. Without limitation of the foregoing, each Bank 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 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 is not reimbursed for such
expenses by the Borrowers, but without limiting the obligation of the Borrowers to make such reimbursement. Each Bank 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 Banks pursuant to this Section, provided that, if the Agent or its Affiliates is subsequently reimbursed by the Borrowers for
such amounts, it shall refund to the Banks 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, in the judgment of the Agent, be insufficient or become impaired, the Agent may call for additional indemnity from the Banks and cease, or not commence, to take
any action until such additional indemnity is furnished. Any amounts paid by the Banks 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 Event of Default has occurred and is continuing, unless the officers of the Agent immediately responsible for matters concerning this Agreement shall have been notified in a writing specifying such
Event of Default and stating that such notice is a "notice of default" by a Bank or by the Borrowers. Upon receiving such a notice, the Agent shall promptly notify each Bank of such Event 

82

 

of Default and provide each Bank with a copy of such notice and, shall endeavor to provide such notice to the Banks within three (3) Business Days (but without any liability whatsoever in the
event of its failure to do so). Agent shall also furnish the Banks, promptly upon receipt, with copies of all other notices or other information required to be provided by the Borrowers hereunder. 

        12.9    Agent's Authorization; Action by Banks.    Except as otherwise expressly provided herein, whenever the Agent
is authorized and empowered hereunder on behalf of the Banks to give any approval or consent, or to make any request, or to take any other action on behalf of the Banks (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 Banks or the Banks, as applicable hereunder. Action that may be taken by Majority Banks or all of the Banks, as the case may be (as provided for
hereunder) may be taken (i) pursuant to a vote at a meeting (which may be held by telephone conference call) as to which all of the Banks have been given reasonable advance notice, or
(ii) pursuant to the written consent of the requisite percentages of the Banks as required hereunder, provided that all of the Banks are given reasonable advance notice of the requests for such
consent. 

        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
Banks or all of the Banks, 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 judgment of the Agent,
such action or omission may expose the Agent to personal liability 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 Bank (other than the Agent, acting in its capacity as agent) shall be entitled to take any enforcement action of any kind under any of the Loan
Documents. 

        12.11    Collateral Matters.    

        (a)  The
Agent is authorized on behalf of all the Banks, without the necessity of any notice to or further consent from the Banks, from time to time to take any action with
respect to any Collateral or the
Collateral Documents which may be necessary to perfect and maintain a perfected security interest in and Liens upon the Collateral granted pursuant to the Loan Documents. 

        (b)  The
Banks irrevocably authorize the Agent, at its option and in its discretion, to release any Lien granted to or held by the Agent upon any Collateral (i) upon
termination of the Revolving Credit Aggregate Commitment and payment in full of all Indebtedness payable under this Agreement and under any other Loan Document; (ii) constituting property sold
or to be sold or disposed of as part of or in connection with any disposition expressly permitted hereunder; (iii) constituting property in which a Loan Party owned no interest at the time the
Lien was granted or at any time thereafter; or (iv) if approved, authorized or ratified in writing by the Majority Banks, or all the Banks, as the case may be, as provided in
Section 13.10. Upon request by the Agent at any time, the Banks will confirm in writing the Agent's authority to release particular types or items of Collateral pursuant to this
Section 12.11(b). 

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

83

 

hereunder, and may accept fees and other consideration therefor without having to account for the same to the Banks. 

        12.13    Co-Agent or Other Titles.    The Banks identified on the facing page or signature pages of this
Agreement as Co-Lead Arrangers, Arrangers, Documentation Agent or Syndication Agent (if any), or any similar titles, shall not have any right, power, obligation, liability, responsibility
or duty under this Agreement other than those applicable to all Banks as such. Without limiting the foregoing, the Banks so identified as Co-Lead Arrangers, Arrangers, Documentation Agent
or Syndication Agent (or having any similar title) shall not have or be deemed to have any fiduciary relationship with any Bank. Each Bank acknowledges that it has not relied, and will not rely, on
the Bank so identified in deciding to enter into this Agreement or in taking or not taking action hereunder. 

        12.14    Agent's Fees.    Until the Indebtedness has been repaid and discharged in full and no commitment to fund any
loan hereunder is outstanding, the Borrowers shall pay to the Agent, as applicable, an agency 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 Agent's Fees described in this Section 12.14 shall not be refundable under any circumstances. 

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. Furthermore, all financial statements required to be delivered hereunder, subject to year-end audit adjustments thereto and the omission of footnote disclosure in the
case of unaudited statements, shall be prepared in accordance with GAAP. 

        13.2    Consent to Jurisdiction.    The Borrowers, Agent and Banks hereby irrevocably submit to the
non-exclusive jurisdiction of any United States Federal Court or Michigan state court sitting in Detroit, or Grand Rapids, Michigan in any action or proceeding arising out of or relating
to this Agreement or any of the Loan Documents and the Borrowers, Agent and Banks 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. The Borrowers irrevocably consent 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 Company at its address specified on the signature page hereto or by certified mail directed to such address or such other address as may
be designated by Company 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 Banks and the Agent
to serve process in any other manner permitted by law or limit the right of the Banks or the Agent (or any of them) to bring any such action or proceeding against Company or any Subsidiary or any of
its or their property in the courts with subject matter jurisdiction of any other jurisdiction. Each of the Borrowers hereby 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 and the Notes 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 the Borrowers to pay interest on the principal balance of the
Notes is or becomes in excess of the maximum interest rate which the Borrowers are 

84

 

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 with respect to such Bank'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) Each Borrower agrees to pay, or reimburse the
Agent for payment of, within five Business Days of demand therefor (except for closing costs which shall be payable on the Effective Date) (i) all reasonable closing costs and expenses,

out-of-pocket advances, appraisal and accounting fees, and lien search fees incurred by Agent in connection with the commitment, consummation and closing of the loans
contemplated hereby or in connection with the administration of this Agreement or any amendment, refinancing or restructuring of the credit arrangements provided under this Agreement, (ii) all
stamp and other taxes (excluding income, franchise and other similar taxes) and fees payable or determined to be payable in connection with the execution, delivery, filing, recording or amendment of

such taxes or fees, and (iii) all reasonable costs and expenses of the Agent or any of the Banks (including reasonable fees and expenses of house and outside counsel (but without duplication of
fees and expenses for the same services) in connection with any action or proceeding relating to a court order, injunction or other process or decree restraining or seeking to restrain the Agent or
any of the Banks from paying any amount under, or otherwise relating in any way to, any Letter of Credit and any and all reasonable costs and expenses which any of them may incur relative to any
payment under any Letter of Credit. At Agent's option, all of said amounts required to be paid by the Borrowers, if not paid when due, may be charged by Agent as a Prime-based Advance against the
Indebtedness. 

        (b)  Each
Borrower agrees to indemnify and hold Agent and each of the Banks harmless from all loss, cost, damage or liability suffered, or expenses, including reasonable
house and outside attorneys' fees and disbursements (but without duplication of fees and expenses for the same services) reasonably incurred by Agent and the Banks by reason of an Event of Default, or
enforcing the obligations of Company or any Subsidiary under this Agreement or any of the other Loan Documents 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 arising solely as a result of the gross negligence or
willful misconduct of the party seeking to be indemnified under this Section 13.5(b). 

        (c)  Each
Borrower agrees to defend, indemnify and hold harmless Agent and each of the Banks, and their respective employees, agents, officers and directors from and against
any and all claims, demands, penalties, fines, liabilities, settlements, damages, costs or expenses of whatever kind or nature (including without limitation, reasonable attorneys and consultants fees,
investigation and laboratory fees, environmental studies reasonably required by Agent or any Bank in connection with the violation of Hazardous Material Laws, court costs and
out-of-pocket litigation expenses, excluding however, those arising solely as a result of the gross negligence or willful misconduct of the Agent or of the Person seeking
indemnification, as the case may be) 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 Company or any of their respective Subsidiaries in violation of or 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 

85

 

or threatened, settlement reached or governmental order or decree relating to such Hazardous Materials, (iv) if any Event of Default exists and remains uncured, the cost of remediation or
monitoring of all Hazardous Materials in violation of or non-compliance with applicable Hazardous Material Laws from all or any portion of any premises owned by Company or their respective
Subsidiaries, (v) if any Event of Default exists and remains uncured, complying or coming into compliance with all Hazardous Material Laws and/or (vi) if any Event of Default exists and
remains uncured, any violation of Hazardous Material Laws. The obligations of the Borrowers under this Section 13.5(c) shall be in addition to any and all other obligations and liabilities the
Borrowers may have to Agent or any of the Banks at common law or pursuant to any other agreement. 

        13.6    Notices.    Except as expressly provided otherwise in this Agreement, all notices and other communications
provided to any party hereto under this Agreement or any other Loan Document shall be in writing and shall be given by personal delivery, by mail, by reputable overnight courier, by telex or by
facsimile and addressed or delivered to it at its address set forth on Schedule 13.6 or at such other address as may be designated by such party in a notice to the other parties that complies
as to 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
date on which it was sent, unless it is actually received sooner by the named addressee; and any notice, if transmitted by telex or facsimile, shall be deemed given when received (answer back
confirmed in the case of telexes and receipt confirmed in the case of telecopies). Agent may, but, except as specifically provided herein, shall not be required to, take any action on the basis of any
notice given to it by telephone, but the giver of any such notice shall promptly confirm such notice in writing or by telex or facsimile, and such notice will not be deemed to have been received until
such confirmation is deemed received in accordance with the provisions of this Section set forth above. If such telephonic notice conflicts with any such confirmation, the terms of such telephonic
notice shall control. 

        13.7    Further Action.    Each 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 intent and purpose of this Agreement or the Loan Documents, and to provide for Advances under and payment of the Notes, according to the intent and purpose herein and therein expressed. 

        13.8    Successors and Assigns; Participations; Assignments.    

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

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

        (c)  The
Borrowers and Agent acknowledge that each of the Banks may at any time and from time to time, subject to the terms and conditions hereof, assign or grant
participations in such Bank's rights and obligations hereunder (on a pro rata basis only) and under the other Loan Documents to any commercial bank, savings and loan association, insurance company,
pension fund, mutual fund, commercial finance company or other similar institution, the identity of which institution, in the case of assignments, is approved by Company and Agent, such approval not
to be unreasonably withheld or delayed; provided, however, that (i) the approval of the Borrowers shall not be required upon the occurrence and during the continuance of an Event of Default,
(ii) the approval of the Borrowers and Agent shall not be required for any such sale, transfer, 

86

 

assignment or participation to the Affiliate of an assigning Bank, any other Bank or any Federal Reserve Bank and (iii) no assignment shall be made or participation granted to an entity which
is a competitor of the Borrowers and their Subsidiaries without the consent of the Borrowers, which consent may be withheld in the sole discretion of the Borrowers. The Borrowers authorize each Bank
to disclose to any prospective assignee or participant, once approved by the Borrowers and Agent, any and all financial information in such Bank's possession concerning the Borrowers which has been
delivered to such Bank pursuant to this Agreement; provided that each such prospective participant shall execute a confidentiality agreement consistent with the terms of Section 13.11 hereof. 

        (d)  Each
assignment by a Bank of all or any portion of its rights and obligations hereunder and under the other Loan Documents, which assignments shall be on a pro rata
basis, shall be made pursuant to an Assignment Agreement substantially (as determined by Agent) in the form attached hereto as Exhibit I (with appropriate insertions acceptable to Agent)
(provided however that such Bank need not deliver an Assignment Agreement in connection with assignments to such Bank's Affiliates or to a Federal Reserve Bank) and shall be subject to the terms and
conditions hereof, and to the following restrictions: 

        (ii)  each
assignment 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 Bank's aggregate interest in the Revolving Credit (and participations in any outstanding Letters of Credit) and the Term Loans; provided however
that, after giving effect to such assignment, in no event shall the entire remaining amount (if any) of assigning Bank's aggregate interest in the Revolving Credit (and participations in any
outstanding Letters of Credit) and the Term Loans be less than $5,000,000; and 

        (iii)  no
assignment shall be effective unless Agent has received from the assignee (or from the assigning Bank) an assignment fee of $3,500 for each such assignment and such
assignment is accompanied by the relevant tax forms required under Section 13.12 hereof. 

In
connection with any assignment, the Borrowers and Agent shall be entitled to continue to deal solely and directly with the assigning Bank in connection with the interest so assigned until
(x) the Agent shall have received a notice of assignment duly executed by the assigning Bank and an Assignment Agreement (with respect thereto) duly executed by the assigning Bank and each
assignee; and (y) the assigning Bank shall have delivered to the Agent the original of each Note held by the assigning Bank under this Agreement. From and after the date on which the Agent
shall notify the Borrowers and the
assigning Bank that the foregoing conditions shall have been satisfied and all consents (if any) required shall have been given, the assignee thereunder shall be deemed to be a party to this
Agreement. To the extent that rights and obligations hereunder shall have been assigned to such assignee as provided in such notice of assignment (and Assignment Agreement), such assignee shall have
the rights and obligations of a Bank 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). In addition, the assigning Bank, to the extent that rights and obligations hereunder shall have been assigned by it as provided in such notice of assignment (and Assignment Agreement),
but not otherwise, shall relinquish its rights and be released from its obligations under this Agreement and the other Loan Documents. 

Within
five (5) Business Days following the Borrowers' receipt of notice from the Agent that Agent has accepted and executed a notice of assignment and the duly executed Assignment Agreement
and assuming the Borrowers have consented to such assignment (if their consent is required), the Borrowers shall, to the extent applicable, and if requested by the assignee Bank, execute and deliver
to the Agent in exchange for any surrendered Note, new Note(s) payable to the order of the assignee in an amount equal to the amount assigned to it pursuant to such notice of assignment (and
Assignment 

87

 

Agreement), and with respect to the portion of the Indebtedness retained by the assigning Bank, to the extent applicable, new Note(s) payable to the order of the assigning Bank in an amount equal to
the amount retained by such Bank hereunder. Agent, the Banks and the Borrowers acknowledge and agree that any such new Note(s) shall be given in renewal and replacement of the surrendered Notes and
shall not effect or constitute a novation or discharge of the Indebtedness evidenced by any surrendered Note, and each such new Note may contain a provision confirming such agreement. In addition,
promptly following receipt of such Notes, Agent shall prepare and distribute to the Borrowers and the assigning Bank and the assignee Bank a revised Schedule 1.2 to this Agreement setting forth
the applicable new Percentages of the Banks (including the assignee Bank), taking into account such assignment. 

        (e)  Each
Bank agrees that any participation agreement permitted hereunder shall comply with all applicable laws and shall be subject to the following restrictions (which
shall be set forth in the applicable Participation Agreement): 

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

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

        (vi)  such
Bank shall retain the sole right and responsibility to enforce the obligations of the Borrowers relating to the Notes and the other Loan Documents, including,
without limitation, the right to proceed against any Guarantors, or cause 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 (other than a participant which is an Affiliate of such Bank), except
for those matters covered by Section 13.10(a) through (e) and (h) hereof (provided that a participant may exercise approval rights over such matters only on an indirect basis,
acting through such Bank, and the Borrowers, Agent and the other Banks may continue to deal directly with such Bank in connection with such Bank's rights and duties hereunder). Notwithstanding the
foregoing, however, in the case of any participation granted by any Bank hereunder, the participant shall not have any rights under this Agreement or any of the other Loan Documents (the participant's
rights against such Bank in respect of such participation to be those set forth in the agreement executed by such Bank in favor of the participant relating thereto) and all amounts payable by the
Borrowers hereunder shall be determined as if such Bank had not sold such participation, provided, however, that such participant shall be entitled to the benefits of this Section 13.8(e) with
respect to rights of setoff under Section 9.6 and the benefit of Section 11 hereof, and provided further, however, that no participant shall be entitled to receive any greater amount
pursuant to such Sections than the issuing Bank would have been entitled to receive in respect of the amount of the participation transferred by such issuing Bank to such participant had no such
transfer occurred. 

        (f)    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 Banks, the Percentages of such Banks and the principal amount of each type of Advance owing to each such Bank from time to time. The entries in the Register shall be conclusive
evidence, absent manifest error, and the Borrowers, the Agent, and the Banks 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 any of the Borrowers or any Bank 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 Borrowers of the making of any entry in the Register or any change in such entry. 

88

  

        (g)  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. 

        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 Company or any Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Majority Banks (or by the Agent at
the written request of the Majority Banks) or, if this Agreement expressly so requires with respect to the subject matter thereof, by all Banks (and, with respect to any amendments to this Agreement
or the other Loan Documents, by Borrowers or the Guarantors which 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, (X) that no amendment, waiver or consent shall increase the Percentage or the stated commitment amounts applicable to any Bank unless approved, in
writing, by the affected Bank and (Y) that no amendment, waiver or consent shall, unless in writing and signed by all the Banks (or, where so indicated, a Supermajority of the applicable
Banks), do any of the following: (a) increase the maximum aggregate principal amounts of the Term Loan, (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, except in the case of any mandatory prepayment of principal under Section 4.13 hereof, which shall require the approval of a Supermajority of the Banks, (d) waive any Event of
Default specified in Section 9.1(a) hereof (e) except as expressly permitted hereunder or under the Collateral Documents, release or defer the granting or perfecting of a lien or
security interest in all or substantially all or any material part of the Collateral (other than the release or deferral of any leasehold mortgage which shall be approved by the Majority Banks) or
release any guaranty or similar undertaking provided by any Person, provided however that Agent shall be entitled to release any Collateral or Guaranty in connection with any sale or other transfer by
any Borrower or any Subsidiary which is permitted under the terms of this Agreement or the other Loan Documents without notice to or any further action or consent of the Banks, (f) terminate or
modify any indemnity provided to the Banks hereunder or under the other Loan Documents, except as shall be otherwise expressly provided in this Agreement or any other Loan Document, (g) take
any action or amend any provision which requires the approval or consent of all Banks pursuant to the terms of this Agreement or any other Loan Document, or (h) change the definitions of
"Revolving Credit Percentage", "Term Loan Percentage", "Weighted Percentage", "Interest Periods","Majority Banks", "Majority Revolving Credit Banks", "Majority Term Loan Banks", "Weighted Percentage"
or this
Section 13.10. Notwithstanding the foregoing, (A) the Revolving Credit Maturity Date may be extended (subject to the terms and conditions of Section 2.16 hereof) only with the
consent of Revolving Credit Banks holding aggregate percentages of eighty percent (80%) or more of the Revolving Credit Maximum Amount; (B) any date fixed for payment of principal or mandatory
prepayment of or interest on any Term Loan may be postponed or extended with the consent of all the applicable Term Loan Banks, except in the case of any mandatory prepayment of principal under
Section 4.13 hereof, which shall require the approval of a Supermajority of the affected Term Loan Banks, (C) no amendment, waiver or consent shall, unless in writing signed by the Swing
Line Bank, 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; (D) no amendment, waiver, or consent shall, unless in writing and signed by the Issuing Bank, affect the rights or duties of the Issuing Bank under Article 3 hereof and
(E) no amendment, waiver, or consent shall, unless in writing and signed by 

89

 

the Agent in addition to all the Banks, affect the rights or duties of the Agent under this Agreement or any other Loan Document. All references in this Agreement to "Banks" or "the Banks" shall
refer to all Banks, unless expressly stated to refer to Majority Banks (or the like). 

        13.11    Confidentiality.    Each Bank agrees that it will not disclose without the prior consent of the Borrowers
(other than to its employees, its Subsidiaries, another Bank, an Affiliate of a Bank or to its auditors or counsel) any information with respect to the Borrowers, which is furnished pursuant to this
Agreement or any of the other Loan Documents; provided that any Bank may disclose any such information (a) as has become generally available to the public or has been lawfully obtained by such
Bank from any third party under no duty of confidentiality to the Borrowers, (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 Bank, 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 or ruling
applicable to such Bank, and (e) to any permitted transferee or assignee or to any approved participant of, or with respect to, the Notes, as aforesaid; provided that each such Person executed
a confidentiality agreement consistent with the terms of this Section 13.11. 

        13.12    Withholding Taxes.    If any Bank is not a United States person within the meaning of
Section 7701(a)(30) of the Internal Revenue Code such Bank shall promptly (but in any event prior to the initial payment of interest hereunder) 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 Bank's domicile
which provides for the exemption from withholding on interest payments to such Bank, (ii) Internal Revenue Service Form W-8ECI or any successor form evidencing that the
income to be received by such Bank 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
Bank is exempt from United States income tax withholding with respect to such income; provided, however, that such Bank shall not be required to deliver to Agent the aforesaid forms or other evidence
with respect to Advances to the Borrowers, if such Bank has assigned its entire interest in the Revolving Credit (including any outstanding Advances thereunder and participations in Letters of Credit
issued hereunder), Swing Line and the Term Loans and any Notes issued to it by the Borrowers, to an Affiliate which is incorporated under the laws of the United States or a state thereof, and so
notifies the Agent. Such Bank 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 Bank hereunder were subject to United States income tax withholding when made, such Bank 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 at the sole expense of the Borrowers, each Bank and
the Agent shall (to the extent it is able to do so based upon applicable facts and circumstances), complete and provide the Borrowers with such forms, certificates or other documents as may be
reasonably necessary to allow the Borrowers, 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 right and benefits (including without limitation economic benefits) available to such of the Bank or the Agent, as the case may be, under this Agreement or any of the other Loan
Documents, or under or in connection with any transactions not related to the transactions contemplated hereby. 

        13.13    Taxes and Fees.    Should any tax (other than as a result of a Bank's failure to comply with
Section 13.12 or a tax based upon the net income or capitalization of any Bank or the Agent by any 

90

 

jurisdiction where a Bank or Agent is or has been located), 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, the Borrowers agree to pay the same, together with any interest or penalties thereon arising from the Borrowers' act or omission, and agrees to hold the Agent and the
Banks harmless with respect thereto. Notwithstanding the foregoing, nothing contained in this Section 13.13 shall affect or reduce the rights of any Bank or the Agent under Section 11.5
hereof. 

        13.14    WAIVER OF JURY TRIAL.    THE BANKS, THE AGENT AND THE BORROWERS 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 BANKS, THE AGENT, NOR THE BORROWERS 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 BANKS AND THE AGENT OR THE BORROWERS EXCEPT BY A WRITTEN INSTRUMENT EXECUTED BY ALL OF THEM. 

        13.15    Joint and Several Liability of Borrowers; Foreign Subsidiaries.    

        (a)  Each
Borrower (other than the Company) authorizes the Company with full power and authority as attorney-in-fact, to execute and deliver Requests
for Advances, request for issuance of Letters of Credit and each other instrument, certificate and report to be delivered by the Borrowers to Agent and the
Lenders pursuant to this Agreement. Each Borrower (other than the Company) agrees that it shall be bound by any action taken by the Company on its behalf pursuant to such appointment. 

        (b)  Each
of the Borrowers acknowledges and agrees that it is the intent of the parties that each such Borrower be primarily liable for the obligations as a joint and several
obligor (except as specifically set forth in this Section 13.21). It is the intention of the parties that with respect to liability of any Borrower hereunder arising solely by reason of its
being jointly and severally liable for Advances and other extensions of credit taken by the Borrowers, the obligations of such Borrower shall be absolute, unconditional and irrevocable irrespective
of: 

        (i)    any
lack of validity, legality or enforceability of this Agreement or any Note as to any Borrower, as the case may be; 

        (ii)  the
failure of any Bank or any holder of any Note: 

        (A)  to
enforce any right or remedy against any Borrower, as the case may be, or any other Person (including any Guarantor) under the provisions of this Agreement, such Note,
or otherwise, or 

        (B)  to
exercise any right or remedy against any guarantor of, or collateral securing, any obligations; 

        (iii)  any
change in the time, manner or place of payment of, or in any other term of, all or any of the Indebtedness, or any other extension, compromise or renewal of any
Indebtedness; 

        (iv)  any
reduction, limitation, impairment or termination of any Indebtedness with respect to any Borrower, as the case may be, for any reason, including any claim of
waiver, release, surrender, alteration or compromise, and shall not be subject to (and each of the Borrowers hereby waive any right to or claim of) any defense (other than the defense of payment in
full of the Indebtedness) or setoff, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality, nongenuineness, irregularity, compromise, 

91

 

unenforceability of, or any other event or occurrence affecting, any Indebtedness with respect to any Borrower, as the case may be; 

        (v)  any
addition, exchange, release, surrender or nonperfection of any collateral, or any amendment to or waiver or release or addition of, or consent to departure from, any
guaranty, held by any Bank or any holder of the Notes securing any of the Indebtedness; or 

        (vi)  any
other circumstance which might otherwise constitute a defense (other than the defense of payment in full of the Indebtedness) available to, or a legal or equitable
discharge of, any Borrower, as the case may be, any surety or any guarantor. 

        (c)  Each
of the Borrowers agrees that its joint and several liability hereunder shall continue to be effective or be reinstated, as the case may be, if at any time any
payment (in whole or in part) of any of the Indebtedness is rescinded or must be restored by any Bank or any holder of any Note, upon the insolvency, bankruptcy or reorganization of any Borrower, as
the case may be, as though such payment had not been made; 

        (d)  Each
of the Borrowers hereby expressly waives: (i) notice of the Banks' acceptance of this Agreement; (ii) notice of the existence or creation or non
payment of all or any of the Indebtedness other than notices expressly provided for in this Agreement; (iii) presentment, demand, notice of dishonor, protest, and all other notices whatsoever
other than notices expressly provided for in this Agreement; and (iv) all diligence in collection or protection of or realization upon the Indebtedness or any part thereof, any obligation
hereunder, or any security for or guaranty of any of the foregoing. 

        (e)  No
delay on any of the Banks part in the exercise of any right or remedy shall operate as a waiver thereof, and no single or partial exercise by any of the Banks of any
right or remedy shall preclude other or further exercise thereof or the exercise of any other right or remedy. No action of any of the Banks permitted hereunder shall in any way affect or impair any
such Banks' rights or any Borrower's Indebtedness under this Agreement. 

        (f)    Each
of the Borrowers hereby represents and warrants to each of the Banks that it now has and will continue to have independent means of obtaining information concerning
the Borrowers' affairs, financial condition and business. Banks shall not have any duty or responsibility to provide any Borrower with any credit or other information concerning such Borrower's
affairs, financial condition or business which may come into the Banks' possession. 

        (g)  Each
of the Borrowers represents and warrants (i) that the business operations of the Borrowers are interrelated and complement one another, and such entities
have a common business purpose, and (ii) that, to permit their uninterrupted and continuous operations, such entities now require and will from time to time hereafter require funds and credit
accommodations for general business purposes and that (iii) the proceeds of advances under the Revolving Credit, the Swing Line, the Term Loan and other credit facilities extended hereunder
will directly or indirectly benefit the Borrowers hereunder, severally and jointly, regardless of which Borrower receives part or all of the proceeds of such Advances. 

        (h)  Notwithstanding
anything to the contrary contained herein, it is the intention of the Borrowers, Agent and the Banks that the amount of the respective Borrowers'
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
Borrowers' 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 Borrowers' respective obligations hereunder shall be limited to the largest amount which, after giving effect thereto, would not, 

92

 

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 13.21(h), then the amount of such excess shall, from and after the time of payment by the Borrowers (or any of them), be
reimbursed by the Banks upon demand by such Borrowers. The foregoing proviso is intended solely to preserve the rights of the Agent and the Banks hereunder against the Borrowers to the maximum extent
permitted by Applicable Insolvency Laws and neither any Borrower nor any Guarantor nor any other Person shall have any right or claim under this Section 13.21(h) that would not otherwise be
available under Applicable Insolvency Laws. 

        (i)    Notwithstanding
anything to the contrary in this Agreement, no Foreign Subsidiary shall be liable under any provision of this Agreement for repayment of the Indebtedness
or for any damages resulting from a Default or Event of Default, other than a Default or Event of Default by such Foreign Subsidiary. 

        13.16    Complete Agreement; Conflicts.    This Agreement, the Notes (if issued), any Requests for Revolving Credit
Advance, Term Loan Rate Requests and Requests for Swing Line Advance hereunder, 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. 

        13.17    Severability.    In case any one or more of the obligations of the Borrowers 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 Borrowers 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
Borrowers under this Agreement, the Notes or any of the other Loan Documents in any other jurisdiction. 

        13.18    Table of Contents and Headings.    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. 

        13.19    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 applicable whether such action is taken directly or indirectly by such Person, whether
or not expressly specified in such provision. 

        13.20    Independence of Covenants.    Each covenant hereunder shall be given independent effect (subject to any
exceptions stated in such covenant) so that if a particular action or condition is not permitted by any such covenant (taking into account any such stated exception), the fact that it would be
permitted by an exception to, or would be otherwise within the limitations of, another covenant shall not avoid the occurrence of a Default or an Event of Default. 

        13.21    Reliance on and Survival of Various Provisions.    All terms, covenants, agreements, representations and
warranties of the Borrowers or any party to any of the Loan Documents made herein or in any of the Loan Documents or in any certificate, report, financial statement or other document furnished by or
on behalf of Company or any Subsidiary in connection with this Agreement or any of the Loan Documents shall be deemed to have been relied upon by the Banks, notwithstanding any investigation
heretofore or hereafter made by any Bank or on such Bank's behalf, and those covenants and agreements of the Borrowers set forth in Section 13.5 hereof (together with any other indemnities of
Company or any Subsidiary contained elsewhere in this Agreement or in any of the other Loan Documents) and of Banks set forth in Section 12.7 hereof shall survive the repayment in full of the
Indebtedness and the termination of the Revolving Credit Aggregate Commitment.
