of such Advance, plus the amount of any other outstanding Revolving Credit
Advance to be then combined therewith having the same Eurodollar-Interest
Period, if any, shall be at least $500,000 (or a larger integral multiple of
$100,000) or the remainder available under the Revolving Credit Aggregate
Commitment if less than $500,000 and at any one time there shall not be in
effect more than five (5) different Eurodollar-Interest Periods;
	 
	 	(f)	 	a Request for Revolving Credit Advance, once delivered to
Agent, shall not be revocable by Borrowers and shall constitute a certification
by Borrowers as of the date thereof that:

	 	(ii)	 	all conditions to the making of Revolving
Credit Advances set forth in this Agreement have been satisfied
(including, without limitation, the delivery of the Borrowing Base
Certificate as required in accordance with Section 7.2(b) hereof), and
shall remain satisfied to the date of such Revolving Credit Advance
(both before and immediately after giving effect to such Revolving
Credit Advance); and
	 
	 	(iii)	 	there is no Default or Event of Default in
existence, and none will exist upon the making of such Revolving Credit
Advance (both before and immediately after giving effect to such
Revolving Credit Advance).

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

36

 

request. Each
telephone or email request for an Advance from an Authorized Signer for Borrowers 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 Lender by wire, telex or telephone
(confirmed by wire, telecopy or telex) of the amount of such Advance being requested and the date
such Revolving Credit Advance is to be made by each Revolving Credit Lender in an amount equal to
its Revolving Credit Percentage of such Advance. Unless such Revolving Credit Lender’s commitment
to make Revolving Credit Advances hereunder shall have been suspended or terminated in accordance
with this Agreement, each such Revolving Credit Lender shall make available the amount of its
Revolving Credit Percentage of each Revolving Credit Advance in immediately available funds to
Agent, at the office of Agent (which shall be for the account of the Eurodollar Lending Office of
the Agent if with respect to Eurodollar-based Advances) located at One Detroit Center, Detroit,
Michigan 48226, not later than 1:00 p.m. (Detroit time) 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
Borrowers the aggregate of the amounts so received by it from the Revolving Credit Lenders in like
funds and currencies:

	 	(i)	 	for Prime-based Advances, not later than 4:00
p.m. (Detroit time) on the date of such Revolving Credit Advance, by
credit to an account of Borrowers maintained with Agent or to such
other account or third party as Borrowers may reasonably direct in
writing, provided such direction is timely given; and
	 
	 	(ii)	 	for Eurodollar-based Advances, not later than
4:00 p.m. (Eastern Standard Time) on the date of such Revolving Credit
Advance, by credit to an account of Borrowers maintained with Agent’s
Correspondent (at the office of the Agent in Detroit) or to such other
account or third party as Borrowers may direct, provided such direction
is timely given.

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

37

 

amount
forthwith upon Agent’s demand therefor and the Agent has in fact made a corresponding amount
available to Borrowers, the Agent shall promptly notify Borrowers and Borrowers shall pay such
amount to Agent, if such notice is delivered to 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, and such
amount paid by Borrowers shall be applied as a prepayment of the Revolving Credit (without any
corresponding reduction in the Revolving Credit Aggregate Commitment), reimbursing Agent for having
funded said amounts on behalf of such Revolving Credit Lender. Borrowers shall retain their claim
against such Revolving Credit Lender with respect to such Revolving Credit Lender’s failure to make
its Percentage of such Advance available and the amounts repaid by it to Agent and, if such
Revolving Credit Lender subsequently makes such amounts available to Agent, Agent shall promptly
make such amounts available to Borrowers as a Revolving Credit Advance. Agent shall also be
entitled to recover from such Revolving Credit Lender or 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 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 Lender,
for the first two (2) Business Days such amount remains unpaid, the
Federal Funds Effective Rate, and thereafter, at the rate of interest
then applicable to such Revolving Credit Advances; and
	 
	 	(ii)	 	in the case of Borrowers, the rate of interest
then applicable to such Advance of the Revolving Credit.

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

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

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

	 	(i)	 	Swing Line Lender shall maintain in accordance
with its usual practice an account or accounts evidencing indebtedness
of Borrowers to Swing Line Lender resulting from each Swing Line
Advance from time to time, including the amount and date of each

38

 

	 	 	 	Swing
Line Advance, its Applicable Interest Rate, its Interest Period, if
any, and the amount and date of any repayment made on any Swing Line
Advance from time to time. The entries made in such account or accounts
of Swing Line Lender shall be prima facie evidence, absent manifest
error, of the existence and amounts of the obligations of Borrowers
therein recorded; provided, however, that the failure of Swing Line
Lender to maintain such account, as applicable, or any error therein,
shall not in any manner affect the obligation of Borrowers to repay the
Swing Line Advances (and all other amounts owing with respect thereto)
in accordance with the terms of this Agreement.
	 
	 	(ii)	 	Borrowers agree that, upon the written request
of Swing Line Lender, Borrowers will execute and deliver to Swing Line
Lender a Swing Line Note.
	 
	 	(iii)	 	Borrowers unconditionally promise to pay to
the Swing Line Lender the then unpaid principal amount of such Swing
Line Advance (plus all accrued and unpaid interest) on the Revolving
Credit Maturity Date and on such other dates and in such other amounts
as may be required from time to time pursuant to this Agreement.
Subject to the terms and conditions hereof, each Swing Line Advance
shall, from time to time after the date of such Advance (until paid),
bear interest at its Applicable Interest Rate.

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

	 	(i)	 	each such Request for Swing Line Advance shall
set forth the information required on the Request for Advance,
including without limitation, (A) the proposed date of such Swing Line
Advance, which must be a Business Day, (B) whether such Swing Line
Advance is to be a Prime-based Advance or a Quoted Rate Advance, and
(C) in the case of a Quoted Rate Advance, the duration of the Interest
Period applicable thereto;
	 
	 	(ii)	 	on the proposed date of such Swing Line
Advance, after giving effect to all outstanding requests for Swing Line
Advances made by Borrowers as of the date of determination, the
aggregate principal amount of all Swing Line Advances outstanding on
such date shall not exceed the Swing Line Maximum Amount;
	 
	 	(iii)	 	on the proposed date of such Swing Line
Advance, after giving effect to all outstanding requests for Revolving
Credit Advances and Swing Line Advances and Letters of Credit requested
by

39

 

	 	 	 	Borrowers on such date of determination (including, without
duplication, Advances that are deemed disbursed pursuant to Section 3.6
hereof), the sum of (x) the aggregate principal amount of all Revolving
Credit Advances and the Swing Line Advances outstanding on such date
plus (y) the Dollar Amount of all Letter of Credit Obligations on such
date shall not exceed the lesser of (A) the Revolving Credit Aggregate
Commitment and (B) the then applicable Borrowing Base;
	 
	 	(iv)	 	(A) in the case of a Swing Line Advance that is
a Prime-based Advance, the principal amount of the initial funding of
such Advance, as opposed to any refunding or conversion thereof, shall
be at least $250,000 or such lesser amount as may be agreed to by the
Swing Line Lender, and (B) in the case of a Swing Line Advance that is
a Quoted Rate Advance, the principal amount of such Advance, plus any
other outstanding Swing Line Advances to be then combined therewith
having the same Interest Period, if any, shall be at least $250,000 or
such lesser amount as may be agreed to by the Swing Line Lender, and at
any time there shall not be in effect more than three (3) Interest
Rates and Interest Periods;
	 
	 	(v)	 	each such Request for Swing Line Advance shall
be delivered to the Swing Line Lender by 3:00 p.m. (Detroit time) on
the proposed date of the Swing Line Advance;
	 
	 	(vi)	 	each Request for Swing Line Advance, once
delivered to Swing Line Lender, shall not be revocable by Borrowers,
and shall constitute and include a certification by Borrowers as of the
date thereof that:

	 	(A)	 	all conditions to the making of
Swing Line Advances set forth in this Agreement shall have been
satisfied (including, without limitation, the delivery of the
Borrowing Base Certificate as required in accordance with
Section 7.2(b) hereof) and shall remain satisfied to the date of
such Swing Line Advance (both before and immediately after
giving effect to such Swing Line Advance);
	 
	 	(B)	 	there is no Default or Event of
Default in existence, and none will exist upon the making of
such Swing Line Advance (both before and immediately after
giving effect to such Swing Line Advance); and
	 
	 	(C)	 	the representations and
warranties of the Credit Parties contained in this Agreement and
the other Loan Documents are true and correct in all material
respects and shall be true and correct in all material respect
as of the date of the

40

 

	 	 	 	making of such Swing Line Advance (both
before and immediately after giving effect to such Swing Line
Advance), other than any representation or warranty that
expressly speaks only as of a different date;

	 	(vii)	 	So long as Agent is the Swing Line Lender, if
Company requests, and Agent, in its sole discretion, agrees, Borrowers
may utilize the Agent’s “Sweep to Loan” automated system for obtaining
Swing Line Advances and making periodic repayments thereunder, subject
to revocation by Agent at any time and from time to time. At any time
during which the “Sweep to Loan” system is in effect, Swing Line
Advances shall be advanced to fund borrowing needs pursuant to the
terms of the Sweep Agreement. Each time a Swing Line Advance is made
using the “Sweep to Loan” system, Borrowers shall be deemed to have
certified to the Agent and the Lenders each of the matters set forth in
clause (vi) of this Section 2.5(b). Principal and interest on Swing
Line Advances requested, or deemed requested, pursuant to this Section
shall be paid pursuant to the terms and conditions of the Sweep
Agreement without any deduction, setoff or counterclaim whatsoever.
Unless sooner paid pursuant to the provisions hereof or the provisions
of the Sweep Agreement, the principal amount of the Swing Line Advances
shall be paid in full, together with accrued interest thereon, on the
Revolving Credit Maturity Date. Agent may suspend or revoke 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 Borrowers for
the funding of Swing Line Advances hereunder (or otherwise), and the
regular procedures set forth in this Section 2.5 for the making of
Swing Line Advances shall be deemed immediately to apply. Agent may, at
its option, also elect to make Swing Line Advances upon Borrowers’
telephone requests on the basis set forth in the last paragraph of
Section 2.3, provided that Borrowers comply with the provisions set
forth in this Section 2.5.

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

41

 

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

	 	(i)	 	The Agent, at any time in its sole and absolute
discretion, may, in each case on behalf of Borrowers (which hereby
irrevocably direct the Agent to act on their behalf) request each of
the Revolving Credit Lenders (including the Swing Line Lender in its
capacity as a Revolving Credit Lender) to make an Advance of the
Revolving Credit to Borrowers, in an amount equal to such Revolving
Credit Lender’s Revolving Credit Percentage of the aggregate principal
amount of the Swing Line Advances outstanding on the date such notice
is given (the “Refunded Swing Line Advances”); provided however that
the Swing Line Advances carried at the Quoted Rate which are refunded
with Revolving Credit Advances at the request of the Swing Line Lender
at a time when no Default or Event of Default has occurred and is
continuing shall not be subject to Section 11.1 and no losses, costs or
expenses may be assessed by the Swing Line Lender against Borrowers or
the Revolving Credit Lenders as a consequence of such refunding. The
applicable Revolving Credit Advances used to refund any Swing Line
Advances shall be Prime-based Advances. In connection with the making
of any such Refunded Swing Line Advances or the purchase of a
participation interest in Swing Line Advances under Section 2.5(e)(ii)
hereof, the Swing Line Lender shall retain its claim against 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(i)
hereof shall have occurred (in which event the procedures of Section
2.5(e)(ii) shall apply) and regardless of whether the conditions
precedent set forth in this Agreement to the making of a Revolving
Credit Advance are then satisfied (but subject to Section 2.5(e)(iii)),
each Revolving Credit Lender shall make the proceeds of its Revolving
Credit Advance available to the Agent for the benefit of the Swing Line
Lender at the office of the Agent specified in Section 2.4(a) hereof
prior to 11:00 a.m. Detroit time on the Business Day next succeeding
the date such notice is given, in immediately available funds. The
proceeds of such Revolving Credit Advances shall be immediately applied
to repay the Refunded Swing Line Advances, subject to Section 11.1
hereof.
	 
	 	(ii)	 	If, prior to the making of an Advance of the
Revolving Credit pursuant to Section 2.5(e)(i) hereof, one of the
events described in Section 9.1(i) hereof shall have occurred, each
Revolving Credit Lender will, on the date such Advance of the Revolving
Credit was
to have been made, purchase from the Swing Line Lender an undivided
participating interest in each Swing Line Advance that was to have
been refunded in an amount equal to its Revolving Credit Percentage
of such Swing Line Advance. Each Revolving

42

 

	 	 	 	Credit Lender within the
time periods specified in Section 2.5(e)(i) hereof, as applicable,
shall immediately transfer to the Agent, for the benefit of the Swing
Line Lender, in immediately available funds, an amount equal to its
Revolving Credit Percentage of the aggregate principal amount of all
Swing Line Advances outstanding as of such date. Upon receipt
thereof, the Agent will deliver to such Revolving Credit Lender a
Swing Line Participation Certificate evidencing such participation.
	 
	 	(iii)	 	Each Revolving Credit Lender’s obligation to
make Revolving Credit Advances to refund Swing Line Advances, and to
purchase participation interests, in accordance with Section 2.5(e)(i)
and (ii), respectively, shall be absolute and unconditional and shall
not be affected by any circumstance, including, without limitation, (A)
any set-off, counterclaim, recoupment, defense or other right which
such Revolving Credit Lender may have against Swing Line Lender,
Borrowers or any other Person for any reason whatsoever; (B) the
occurrence or continuance of any Default or Event of Default; (C) any
adverse change in the condition (financial or otherwise) of any
Borrower or any other Person; (D) any breach of this Agreement or any
other Loan Document by any Borrower or any other Person; (E) any
inability of any Borrower to satisfy the conditions precedent to
borrowing set forth in this Agreement on the date upon which such
Revolving Credit Advance is to be made or such participating interest
is to be purchased; (F) the termination of the Revolving Credit
Aggregate Commitment hereunder; or (G) any other circumstance,
happening or event whatsoever, whether or not similar to any of the
foregoing. If any Revolving Credit Lender does not make available to
the Agent the amount required pursuant to Section 2.5(e)(i) or (ii)
hereof, as the case may be, the Agent on behalf of the Swing Line
Lender, shall be entitled to recover such amount on demand from such
Revolving Credit Lender, together with interest thereon for each day
from the date of non-payment until such amount is paid in full (x) for
the first two (2) Business Days such amount remains unpaid, at the
Federal Funds Effective Rate and (y) thereafter, at the rate of
interest then applicable to such Swing Line Advances. The obligation of
any Revolving Credit Lender to make available its pro rata portion of
the amounts required pursuant to Section 2.5(e)(i) or (ii) hereof shall
not be affected by the failure of any other Revolving Credit Lender to
make such amounts available, and no Revolving Credit Lender shall have
any liability to any Credit Party, the Agent, the Swing Line Lender, or
any other Revolving Credit Lender or any
other party for another Revolving Credit Lender’s failure to make
available the amounts required under Section 2.5(e)(i) or (ii)
hereof.

43

 

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

     2.6 Interest Payments; Default Interest.

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

     (b) Interest on each Eurodollar-based Advance of the Revolving Credit shall accrue at its
Eurodollar-based Rate and shall be payable in immediately available funds on the last day of the
Eurodollar-Interest Period applicable thereto (and, if any Eurodollar-Interest Period shall exceed
three months, then on the last Business Day of the third month of such Eurodollar-Interest Period,
and at three month intervals thereafter). Interest accruing at the Eurodollar-based Rate shall be
computed on the basis of a 360 day year and assessed for the actual number of days elapsed from the
first day of the Eurodollar-Interest Period applicable thereto to but not including the last day
thereof.

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

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

44

 

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

     2.7 Optional Prepayments.

     (a) (i) 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 in respect of the Revolving Credit, after giving effect to any partial
prepayment, the aggregate balance of Prime-based Advance(s) of the Revolving Credit remaining
outstanding shall be at least Two Hundred Fifty Thousand Dollars ($250,000), and (ii) subject to
Section 2.10(b) hereof, Borrowers may prepay all or part of the outstanding principal of any
Eurodollar-based Advance of the Revolving Credit at any time (subject to not less than three (3)
Business Day’s notice to Agent) provided that, after giving effect to any partial prepayment, the
unpaid portion of such Advance which is to be refunded or converted under Section 2.3 hereof shall
be at least Five Hundred Thousand Dollars ($500,000).

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

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

     2.8 Prime-based Advance in Absence of Election or Upon Default.
If, (a) as to any outstanding Eurodollar-based Advance of the Revolving Credit or any
outstanding Quoted Rate Advance of the Swing Line, Agent has not received payment of all
outstanding principal and accrued interest on the last day of the Interest Period applicable
thereto, or does not receive a timely Request for Advance meeting the requirements of Section 2.3
or 2.5 hereof with respect to the refunding or conversion of such Advance, or (b) 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

45

 

day of the applicable Interest Period the principal amount of any
Eurodollar-based Advance or Quoted Rate Advance, as the case may be, which has not been prepaid
shall, absent a contrary election of the Majority Revolving Credit Lenders, be converted
automatically to a Prime-based Advance and the Agent shall thereafter promptly notify Borrowers of
said action. All accrued and unpaid interest on any Advance converted to a Prime-based Advance
under this Section 2.8 shall be due and payable in full on the date such Advance is converted.

     2.9 Revolving Credit Facility Fee. From the Effective Date to the Revolving Credit
Maturity Date, Borrowers shall pay to the Agent for distribution to the Lenders pro-rata in
accordance with their respective Percentages, a Revolving Credit Facility Fee quarterly in arrears
commencing July 1, 2008, and on the first day of each calendar quarter thereafter (in respect of
the prior three months or any portion thereof). The Revolving Credit Facility Fee payable to each
Lender 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 Lender of
its share of the Revolving Credit Facility Fee based upon its respective Percentage. It is
expressly understood that the Revolving Credit Facility Fees described in this Section are not
refundable.

     2.10 Mandatory Repayment of Revolving Credit Advances.

     (a) If at any time and for any reason the aggregate outstanding principal amount of Revolving
Credit Advances plus Swing Line Advances, plus the amount of all outstanding Letter of Credit
Obligations (as determined based on the Dollar Amount of such Letter of Credit Obligations), shall
exceed the lesser of (i) the Revolving Credit Aggregate Commitment and (ii) the then applicable
Borrowing Base (such amount, the “Excess”), 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, repay any Revolving Credit Advances and Swing Line Advances in an amount
equal to the lesser of the outstanding amount of such Advances and the amount of such remaining
Excess, with such amounts to be applied between the Revolving Credit Advances and Swing Line
Advances as determined by the Agent and then, to the extent that any excess remains after payment
in full of all Revolving Credit Advances and Swing Line Advances, to provide cash collateral in
support of any Letter of Credit Obligations in an amount equal to the lesser of (x) 105% of the
Dollar Amount of such Letter of Credit Obligations and (y) the amount of such Excess, with such
cash collateral to be provided on the
basis set forth in Section 9.2 hereof; provided that, if any such excess shall exist solely as
a result of an adjustment to the Borrowing Base as a result of any reserves established by Agent
thereunder, such payment or providing of cash collateral shall not be required to occur until the
third Business Day following the date that Borrower is notified of such Excess. 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. Any
payments made pursuant to this Section shall be applied first to outstanding Prime-based Advances
under the Revolving Credit, next to Swing Line Advances carried at the Prime-based Rate and then to
Eurodollar-based Advances of the Revolving Credit, and then to Swing

46

 

Line Advances carried at the
Quoted Rate. To the extent of any Letters of Credit denominated in an Alternate Currency,
compliance with this Section 2.10(a) shall be tested on a daily or other basis satisfactory to
Agent in its sole discretion, provided that, so long as no Default or Event of Default has occurred
and is continuing, Agent shall not be required to test compliance with this Section 2.10(a) more
than monthly. Notwithstanding the foregoing, if any such Excess shall exist solely as a result of
a currency fluctuation, such payment or providing of cash collateral shall not be required to occur
until the third Business Day following the date that Borrower is notified of such Excess so long as
no Default or Event of Default exists or is continuing at such time.

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

     2.11 Optional Reduction or Termination of Revolving Credit Aggregate Commitment. 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 One Hundred Thousand Dollars ($100,000); (ii) each reduction shall be
accompanied by the payment of the Revolving Credit Facility Fee, if any, accrued and unpaid to the
date of such reduction; (iii) Borrowers shall prepay in accordance with the terms hereof the
amount, if any, by which the aggregate unpaid
principal amount of Revolving Credit Advances and Swing Line Advances (including, without
duplication, any deemed Advances made under Section 3.6 hereof) outstanding hereunder, plus the
Letter of Credit Obligations (as determined based on the Dollar Amount of such Letter of Credit
Obligations), exceeds the amount of the then applicable Revolving Credit Aggregate Commitment as so
reduced, together with interest thereon to the date of prepayment; (iv) no reduction shall reduce
the Revolving Credit Aggregate Commitment to an amount which is less than the aggregate undrawn
amount of any Letters of Credit outstanding at such time; and (v) no such reduction shall reduce
the Swing Line Maximum Amount unless Borrowers so elect, provided that the Swing Line Maximum
Amount shall at no time be greater than the Revolving Credit Aggregate Commitment; provided,
however that if the termination or reduction of the

47

 

Revolving Credit Aggregate Commitment requires
the prepayment of a Eurodollar-based Advance or a Quoted Rate Advance and such termination or
reduction is made on a day other than the last Business Day of the then current Interest Period
applicable to such Eurodollar-based Advance or such Quoted Rate Advance, then, pursuant to Section
11.1, Borrowers shall compensate the Revolving Credit Lenders and/or the Swing Line Lender for any
losses or, so long as no Default or Event of Default has occurred and is continuing, Borrowers may
deposit the amount of such prepayment in a collateral account as provided in Section 2.10(b).
Reductions of the Revolving Credit Aggregate Commitment and any accompanying prepayments of
Advances of the Revolving Credit shall be distributed by Agent to each Revolving Credit Lender in
accordance with such Revolving Credit Lender’s Revolving Percentage thereof, and will not be
available for reinstatement by or readvance to Borrowers, and any accompanying prepayments of
Advances of the Swing Line shall be distributed by Agent to the Swing Line Lender and will not be
available for reinstatement by or readvance to Borrowers. Any reductions of the Revolving Credit
Aggregate Commitment hereunder shall reduce each Revolving Credit Lender’s portion thereof
proportionately (based on the applicable Percentages), and shall be permanent and irrevocable. Any
payments made pursuant to this Section shall be applied first to outstanding Prime-based Advances
under the Revolving Credit, next to Swing Line Advances carried at the Prime-based Rate and then to
Eurodollar-based Advances of the Revolving Credit, and then to Swing Line Advances carried at the
Quoted Rate.

     2.12 Use of Proceeds of Advances. Advances of the Revolving Credit shall be used to
refinance existing debt, to finance the Nitram Acquisition and to provide working capital and for
other lawful corporate purposes.

     2.13 Extension of Revolving Credit Maturity Date.

	 	(a)	 	Provided that no Default or Event of Default has occurred and
is continuing, Borrowers may, by written notice to Agent (with sufficient
copies for each Lender) (which notice shall be irrevocable and which shall not
be deemed effective unless actually received by Agent) prior to December 31,
2010, but not before November 30, 2010, request that the Lenders extend the
then applicable Revolving Credit Maturity Date to a date that is one year later
than the Revolving Credit Maturity Date then in effect (each such request, a
“Request”). Each Lender shall, not later than
sixty (60) days after receipt of such notice (“Lender Notice Date”), give
written notice to the Agent stating whether such Lender is willing to extend
the Revolving Credit Maturity Date as requested. If Agent has received the
aforesaid written approvals of such Request from each of the Lenders, then,
effective upon the date of Agent’s receipt of all such written approvals
from the Lenders, as aforesaid, the Revolving Credit Maturity Date shall be
so extended for an additional one year period from the current date of
maturity, the term Revolving Credit Maturity Date shall mean such extended
date and Agent shall promptly notify Borrowers that such extension has
occurred.
	 
	 	(b)	 	If (i) any Lender gives the Agent written notice that it is
unwilling to extend the Revolving Credit Maturity Date as requested or (ii) any
Lender

48

 

	 	 	 	fails to provide written approval to Agent of such a Request on or
before the applicable Lender Notice Date, then (w) the Lenders shall be deemed
to have declined to extend the Revolving Credit Maturity Date, (x) the
then-current Revolving Credit Maturity Date shall remain in effect (with no
further right on the part of Borrowers to request extensions thereof under this
Section 2.12), and (y) the commitments of the Lenders to make Advances of the
Revolving Credit hereunder shall terminate on the Revolving Credit Maturity
Date then in effect, and Agent shall promptly notify Borrowers thereof.

3. LETTERS OF CREDIT.

     3.1 Letters of Credit. Subject to the terms and conditions of this Agreement, Issuing
Lender shall through the Issuing Office, at any time and from time to time from and after the date

may

51

 

	 	 	 	permit), the Letter of Credit Agreement related thereto, together with such
other documents and materials as may be required pursuant to the terms thereof
and any information relating to the transaction supported by the proposed
Letter of Credit (and the parties to such transaction) reasonably requested by
Issuing Lender to allow it to conduct list-checking or similar measures under
any applicable anti-terrorism law or regulation (including without limitation
those referred to in Section 6.7, 7.4 and 7.16 hereof (all such laws and
regulations, as in effect from time to time, the “Anti-Terrorism Law(s)”) and
the terms of the proposed Letter of Credit shall be reasonably satisfactory to
Issuing Lender;
	 
	 	(f)	 	no order, judgment or decree of any court, arbitrator or
Governmental Authority shall purport by its terms to enjoin or restrain Issuing
Lender from issuing the Letter of Credit requested, or any Revolving Credit
Lender from taking an assignment of its Revolving Credit Percentage thereof
pursuant to Section 3.6 hereof, and no law, rule, regulation, request or
directive (whether or not having the force of law) shall prohibit the Issuing
Lender from issuing, or any Revolving Credit Lender from taking an assignment

governmental agency or authority on transactions involving letters of credit
or on banks generally that, in any case described in this clause (e), would
make it unlawful or unduly burdensome for the Issuing Lender to issue or any
Revolving Credit Lender to take an assignment of its Revolving Credit
Percentage of the requested Letter of Credit or letters of credit generally;
and
	 
	 	(h)	 	Issuing Lender 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 Lender pursuant hereto shall constitute the
certification by Borrowers of the matters set forth in Sections 5.2 hereof. The Agent shall be
entitled to rely on such certification without any duty of inquiry.

     3.3 Notice. The Issuing Lender shall deliver to the Agent, concurrently with or promptly
following its issuance of any Letter of Credit, a true and complete copy of each Letter

52

 

of Credit.
In the case of Standby Letters of Credit, promptly upon its receipt thereof, Agent shall give
notice, substantially in the form attached hereto as Exhibit E-1, to each Revolving Credit Lender
of the issuance of each Standby Letter of Credit, specifying the amount thereof and the amount of
such Revolving Credit Lender’s Percentage thereof. In the case of Documentary Letters of Credit,
Agent shall give notice (a) quarterly and (b) promptly after the occurrence of an Event of Default,
substantially in the form of notice attached hereto as Exhibit E-2, to each Revolving Credit Lender
of the Documentary Letters of Credit then outstanding.

     3.4 Letter of Credit Fees; Increased Costs. (a) Borrowers shall pay letter of credit
fees as follows:

	 	(i)	 	A per annum letter of credit fee with respect
to the undrawn amount of each Standby Letter of Credit issued pursuant
hereto (based on the Dollar Amount of each Standby Letter of Credit) in
the amount of the Applicable Fee Percentage (determined with reference
to Schedule 1.1 to this Agreement) shall be paid to the Agent for
distribution to the Revolving Credit Lenders in accordance with their
Revolving Credit Percentages.
	 
	 	(ii)	 	A letter of credit facing fee on the face
amount of each Letter of Credit shall be paid to the Agent for
distribution to the Issuing Lender for its own account, in accordance
with the terms of the applicable Fee Letter.
	 
	 	(iii)	 	Letter of Credit Fees (including any per annum
fee) in connection with Documentary Letters of Credit as shall be
agreed to between Borrowers and the Issuing Lender, to be paid by the
Borrowers to
the Agent for the benefit of the Revolving Credit Lenders in
accordance with their Revolving Credit Percentages.

	 	(b)	 	All payments by Borrowers to the Agent for distribution to the
Issuing Lender or the Revolving Credit Lenders under this Section 3.4 shall be
made in Dollars in immediately available funds at the Issuing Office or such
other office of the Agent as may be designated from time to time by written
notice to Borrowers by the Agent. The fees described above (i) shall be
nonrefundable under all circumstances, (ii) in the case of fees due under
clause (a)(i) above, shall be payable quarterly in arrears on the last day of
each calendar quarter, (iii) in the case of fees due under clause (a)(ii)
above, shall be payable upon the issuance of such Letter of Credit and upon any
amendment thereto or extension thereof and (iv) in the case of fees due under
clause (a)(iii) above, such fees shall be determined and paid as agreed to
between the Borrowers and the Issuing Lender. The fees due under clause (a)(i)
above shall be determined by multiplying the Applicable Fee Percentage times
the undrawn amount of the face amount of each such Letter of Credit on the date
of determination, and shall be calculated on the basis of a 360 day year and
assessed for the actual number of days from the date of the issuance thereof to
the stated

53

 

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

     3.5 Other Fees. In connection with the Letters of Credit, and in addition to the Letter
of Credit Fees, Borrowers shall pay, for the sole account of the Issuing Lender, standard
documentation, administration, payment and cancellation charges assessed by Issuing Lender or

54

 

the
Issuing Office, at the times, in the amounts and on the terms set forth or to be set forth from
time to time in the standard fee schedule of the Issuing Office in effect from time to time.

     3.6 Participation Interests in and Drawings and Demands for Payment Under Letters of
Credit.

     (a) Upon issuance by the Issuing Lender of each Letter of Credit hereunder (and on the
Effective Date with respect to each Existing Letter of Credit), each Revolving Credit Lender shall
automatically acquire a pro rata participation interest in such Letter of Credit and each related
Letter of Credit Payment based on its respective Revolving Credit Percentage.

     (b) If the Issuing Lender shall honor a draft or other demand for payment presented or made
under any Letter of Credit, Borrowers agree to pay to the Issuing Lender an amount equal to the
amount paid by the Issuing Lender in respect of such draft or other demand under such Letter of
Credit and all reasonable expenses paid or incurred by the Agent relative thereto not later than
1:00 p.m. (Detroit time), in Dollars or, if the applicable Letter of Credit was denominated in an
Alternate Currency, in such Alternate Currency), on (i) the Business Day that 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 Borrowers received such notice, if such
notice is received after 11:00 a.m. (Detroit time).

     (c) If the Issuing Lender shall honor a draft or other demand for payment presented or made
under any Letter of Credit, but Borrowers do not reimburse the Issuing Lender as required under
clause (b) above and the Revolving Credit Aggregate Commitment has not been terminated (whether by
maturity, acceleration or otherwise), the Borrowers shall be deemed to have immediately requested
that the Revolving Credit Lenders make a Prime-based Advance of
the Revolving Credit (which Advance may be subsequently converted at any time into a
Eurodollar-based Advance pursuant to Section 2.3 hereof) in the principal amount equal to the
amount paid by the Issuing Lender in respect of such draft or other demand under such Letter of
Credit and all reasonable expenses paid or incurred by the Agent relative thereto. Agent will
promptly notify the Revolving Credit Lenders of such deemed request, and each such Lender shall
make available to the Agent an amount equal to its pro rata share (based on its Revolving Credit
Percentage) of the Dollar Amount of such Advance.

     (d) If the Issuing Lender shall honor a draft or other demand for payment presented or made
under any Letter of Credit, but Borrowers do not reimburse the Issuing Lender as required under
clause (b) above, and (i) the Revolving Credit Aggregate Commitment has been terminated (whether by
maturity, acceleration or otherwise), or (iii) any reimbursement received by the Issuing Lender
from Borrowers (or any one of them) is or must be returned or rescinded upon or during any
bankruptcy or reorganization of any Credit Party or otherwise, then Agent shall notify each
Revolving Credit Lender, and each Revolving Credit Lender will be obligated to pay the Agent for
the account of the Issuing Lender its pro rata share (based on its Revolving Credit Percentage) of
the Dollar Amount equal to the amount paid by the Issuing Lender in respect of such draft or other
demand under such Letter of Credit and all reasonable expenses paid or incurred by the Agent
relative thereto (but no such payment shall diminish the obligations of the Borrowers hereunder).
Upon receipt thereof, the Agent will deliver to such Revolving Credit Lender a participation
certificate evidencing its participation interest in respect

55

 

of such payment and expenses. To the
extent that a Revolving Credit Lender fails to make such amount available to the Agent by 11:00 am
Detroit time on the Business Day next succeeding the date such notice is given, such Revolving
Credit Lender shall pay interest on such amount in respect of each day from the date such amount
was required to be paid, to the date paid to Agent, at a rate per annum equal to the Federal Funds
Effective Rate. The failure of any Revolving Credit Lender to make its pro rata portion of any
such amount available under to the Agent shall not relieve any other Revolving Credit Lender of its
obligation to make available its pro rata portion of such amount, but no Revolving Credit Lender
shall be responsible for failure of any other Revolving Credit Lender to make such pro rata portion
available to the Agent.

     (e) If the Borrowers fail to deliver to Agent cash collateral as required under Section
3.2(a)(i)(B)(iii), the Agent may, at its option, require that Borrower make a deemed request that
the Revolving Credit Lenders make a Prime-based Advance of the Revolving Credit (which Advance may
be subsequently converted at any time into a Eurodollar-based Advance pursuant to Section 2.3
hereof) in an aggregate amount necessary to satisfy the Borrowers’ obligations to deliver such cash
collateral under Section 3.2(a)(i)(B)(iii). Agent will promptly notify the Revolving Credit
Lenders of such deemed request, and each such Lender shall make available to the Agent an amount
equal to its pro rata share (based on its Revolving Credit Percentage) of the Dollar Amount of such
Advance.

     (f) In the case of any Advance made under this Section 3.6, each such Advance shall be
disbursed notwithstanding any failure to satisfy any conditions for disbursement of any Advance set
forth in Article 2 hereof or Section 5.1 hereof, and, to the extent of the Advance so disbursed,
the Reimbursement Obligation of Borrowers to the Agent under this Section 3.6 or the obligation of
the Borrowers to deliver cash collateral as required under Section 3.2(a)(i)(B)(iii), as the case
may be, shall be deemed satisfied (unless, in each case, taking into account any such
deemed Advances, the aggregate outstanding principal amount of Advances of the Revolving
Credit and the Swing Line, plus the Letter of Credit Obligations (other than the Reimbursement
Obligations to be reimbursed by this Advance) on such date exceed the lesser of the Borrowing Base
or the then applicable Revolving Credit Aggregate Commitment).

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

     (h) Notwithstanding the foregoing however no Revolving Credit Lender shall be deemed to have
acquired a participation in a Letter of Credit if the officers of the Issuing Lender immediately
responsible for matters concerning this Agreement shall have received written notice from Agent or
any Lender at least two (2) Business Days prior to the date of the issuance or extension of such
Letter of Credit or, with respect to any Letter of Credit subject to automatic

56

 

extension, at least
five (5) Business Days prior to the date that the beneficiary under such Letter of Credit must be
notified that such Letter of Credit will not be renewed, that the issuance or extension of Letters
of Credit should be suspended based on the occurrence and continuance of a Default or Event of
Default and stating that such notice is a “notice of default”; provided, however that the Revolving
Credit Lenders shall be deemed to have acquired such a participation upon the date on which such
Default or Event of Default has been waived by the requisite Lenders, as applicable. In the event
that the Issuing Lender receives such a notice, the Issuing Lender shall have no obligation to
issue any Letter of Credit until such notice is withdrawn by Agent or such Lender or until the
requisite Lenders have waived such Default or Event of Default in accordance with the terms of this
Agreement.

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

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

	 	(a)	 	Any lack of validity or enforceability of any Letter of Credit,
any Letter of Credit Agreement, any other documentation relating to any Letter
of Credit, this Agreement or any of the other Loan Documents (the “Letter of
Credit Documents”);
	 
	 	(b)	 	Any amendment, modification, waiver, consent, or any
substitution, exchange or release of or failure to perfect any interest in
collateral or security, with respect to or under any Letter of Credit Document;
	 
	 	(c)	 	The existence of any claim, setoff, defense or other right
which Borrowers may have at any time against any beneficiary or any transferee

terms of any other Loan Document), as applicable, or the validity, binding
effect or enforceability thereof shall be contested by any party thereto (other
than any Lender, Agent, Issuing Lender or 

99

 

	 	 	 	Swing Line Lender), or any Person
(other than any Lender, Agent, Issuing Lender or Swing Line Lender) shall deny
that it has any or further liability or obligation under any such Loan
Document, or any such Loan Document shall be terminated (other than in
accordance with the terms thereof or the terms of any other Loan Document),
invalidated, revoked or set aside or in any way cease to give or provide to the
Lenders and the Agent the benefits purported to be created thereby, or any such
Loan Document purporting to grant a Lien to secure any Indebtedness shall, at
any time after the delivery of such Loan Document, fail to create a valid and
enforceable Lien on any material portion of the Collateral purported to be
covered thereby or such Lien shall fail to cease to be a perfected Lien with
the priority required in the relevant Loan Document.

     9.2 Exercise of Remedies. If an Event of Default has occurred and is continuing
hereunder: (a) the Agent may, and shall, upon being directed to do so by the Majority Revolving
Credit Lenders, declare the Revolving Credit Aggregate Commitment terminated; (b) the Agent may,
and shall, upon being directed to do so by the Majority Lenders, declare the entire unpaid
principal Indebtedness, including the Notes, immediately due and payable, without presentment,
notice or demand, all of which are hereby expressly waived by Borrowers; (c) upon the occurrence of
any Event of Default specified in Section 9.1(i) and notwithstanding the lack of any declaration by
Agent under preceding clauses (a) or (b), the entire unpaid principal Indebtedness shall become
automatically and immediately due and payable, and the Revolving Credit Aggregate Commitment shall
be automatically and immediately terminated; (d) the Agent shall, upon being directed to do so by
the Majority Revolving Credit Lenders, demand immediate delivery of cash
collateral, and each Borrower agrees to deliver such cash collateral upon demand, in an amount
equal to 105% of the maximum amount that may be available to be drawn at any time prior to the
stated expiry of all outstanding Letters of Credit, for deposit into an account controlled by the
Agent; (e) the Agent may, and shall, upon being directed to do so by the Majority Lenders, notify
Borrowers or any Credit Party that interest shall be payable on demand on all Indebtedness (other
than Revolving Credit Advances, Swing Line Advances and Term Loan Advances with respect to which
Sections 2.6 and 4.6 hereof shall govern) owing from time to time to the Agent or any Lender, at a
per annum rate equal to the then applicable Prime-based Rate plus two percent (2%); and (f) the
Agent may, and shall, upon being directed to do so by the Majority Lenders or the Lenders, as
applicable (subject to the terms hereof), exercise any remedy permitted by this Agreement, the
other Loan Documents or law.

     9.3 Rights Cumulative. No delay or failure of Agent and/or Lenders in exercising any
right, power or privilege hereunder shall affect such right, power or privilege, nor shall any
single or partial exercise thereof preclude any further exercise thereof, or the exercise of any
other power, right or privilege. The rights of Agent and Lenders under this Agreement are
cumulative and not exclusive of any right or remedies which Lenders would otherwise have.

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

100

 

connection with this
Agreement. These waivers have been voluntarily given, with full knowledge of the consequences
thereof.

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

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

10. PAYMENTS, RECOVERIES AND COLLECTIONS.

     10.1 Payment Procedure.

     (a) All payments to be made by Borrowers shall be made without condition or deduction for any
counterclaim, defense, recoupment or setoff. Except as otherwise provided herein, all payments
made by Borrowers of principal, interest or fees hereunder shall be made without setoff or
counterclaim on the date specified for payment under this Agreement and must be received by Agent
not later than 1:00 p.m. (Detroit time) on the date such payment is required or intended to be made
in Dollars in immediately available funds to Agent at Agent’s office located at One Detroit Center,
Detroit, Michigan 48226-3289, for the ratable benefit of the Revolving Credit Lenders in the case
of payments in respect of the Revolving Credit and any Letter of Credit Obligations, for the
ratable benefit of the Term Loan Lenders in the case of payments in respect of the Term Loan.
Payments in respect of any Advance in any Alternate Currency shall be made in such Alternate
Currency in immediately available funds for the account of Agent’s Eurocurrency Lending Office, at
Agent’s Correspondent, for the ratable account of the Lenders, not later than 11:00 a.m. (Detroit
time). Any payment received by the

101

 

Agent after 1:00 p.m. (Detroit time) shall be deemed received on
the next succeeding Business Day and any applicable interest or fee shall continue to accrue. Upon
receipt of each such payment, the Agent shall make prompt payment to each applicable Lender, or, in
respect of Eurodollar-based Advances, such Lender’s Eurodollar Lending Office, in like funds and
currencies, of all amounts received by it for the account of such Lender.

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

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

     (d) All payments to be made by Borrowers under this Agreement or any of the Notes (including
without limitation payments under the Swing Line and/or Swing Line Note) shall be made without
setoff or counterclaim, as aforesaid, and, subject to compliance by each Lender (and each assignee
and participant pursuant to Section 13.8, as applicable) with Section 13.13, without deduction for
or on account of any present or future withholding or other taxes of any nature imposed by any
Governmental Authority or of any political subdivision thereof or any federation or organization of
which such Governmental Authority may at the time of payment be a member (other than (x) any such
taxes on capital or the overall income, net income, net profits or net receipts or similar taxes
(or any franchise taxes imposed in lieu of such taxes) on the Agent or any Lender (or any branch
maintained by Agent or a Lender) as a result of a present or former connection between the Agent or
such Lender and the Governmental Authority, political subdivision, federation or organization
imposing such taxes, and (y) any branch profits taxes imposed by the United States of America (all
such taxes, levies, imposts, deductions, charges and withholdings not excluded under the clauses
(x) or (y) of this Section 10.1 being hereinafter referred to as “Taxes”) unless Borrowers are
compelled by law to make payment subject to such tax. In such event, Borrowers shall:

	 	(i)	 	pay to the Agent for Agent’s own account
and/or, as the case may be, for the account of the Lenders such
additional amounts as may be necessary to ensure that the Agent and/or
such Lender or 

102

 

	 	 	 	Lenders (including the Swing Line Lender) receive a net
amount equal to the full amount which would have been receivable had
payment not been made subject to such Tax; and

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

provided, however, that the Borrowers shall not be required to pay any additional amounts
pursuant to Section 10.1(d)(i) or any amounts pursuant to Section 13.14 hereof to the extent
that: (i) the obligation to pay such additional amounts or any amounts under Section 13.14
hereof would not have arisen but for a failure for any reason by such
Lender (or permitted assignee) to comply with its obligations under Section 13.13 to provide
certain forms or other evidence necessary to establish its entitlement to complete exemption
from U.S. withholding tax (other than a failure that results exclusively from the change in
any law, rule, regulation or treaty or in the administration, interpretation or application
thereof by any Governmental Authority after the date on which such Lender (or permitted
assignee) first became a party to this Agreement); (ii) with respect to an assignee Lender,
the obligation to withhold U.S. taxes (other than any such obligation in respect of a
Foreign Subsidiary of any Borrower which becomes a Borrower or Guarantor) existed on the
date such assignee Lender became a party to this Agreement, or with respect to payments to a
lending office newly designated by a Lender (a “New Lending Office”), the date such Lender
designated such New Lending Office with respect to the applicable Loan; provided, however,
that this clause (ii) shall not apply to the extent the additional amounts any Lender (or
transferee) through a New Lending Office, would be entitled to receive (without regard to
this clause (ii)) do not exceed the additional amounts that the person making the transfer,
or Lender (or transferee) making the designation of such New Lending Office, would have been
entitled to receive in the absence of such transfer or designation; (iii) the certifications
made in any forms or other evidence provided by such Lender under Section 13.13 were untrue
or inaccurate on the date delivered in any material respect; (iv) such Lender is claiming an
exemption from withholding of United States Federal income tax under Internal Revenue Code
sections 871(h) or 881(c) but is unable at any time to make the representations and
warranties set forth in clauses (A) — (C) of Section 13.13(a)(1); or (v) such non-U.S.
Lender is treated as a “conduit entity” within the meaning of U.S. Treasury Regulations
Section 1.881-3 or any successor provision.

     In the event Borrowers are required to pay additional amounts to or for the account of any
Lender pursuant to this Section 10.1(d), then such Lender shall use good faith diligent efforts to
file any certificate or document reasonably requested by Borrowers or to designate a Lending Office
from a different jurisdiction (if such Lending Office is maintained by such Lender) so as to
eliminate or reduce any such additional payments by Borrowers which may accrue in the future,
provided Lender shall incur or suffer no material cost or expense as a result thereof. If Agent or
a Lender receives a refund of any Taxes or Other Taxes as to which it has been

103

 

indemnified by
Borrower pursuant to Section 13.14 or with respect to which Borrower has paid additional amounts
pursuant to this Section 10.1(d) (provided that Lenders shall be under no obligation to apply for
or otherwise seek such refund), it shall promptly pay to such Borrower an amount equal to such
refund and any interest paid by the relevant Governmental Authority with respect to such refund,
provided, that Borrower, upon the request of Agent or such Lender, shall repay the amount paid over
to Borrower to Agent or such Lender to the extent that Agent or such Lender is required to repay or
otherwise disgorge the applicable refund to such Governmental Authority.

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

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

11. CHANGES IN LAW OR CIRCUMSTANCES; INCREASED COSTS.

     11.1 Reimbursement of Prepayment Costs. If (i) Borrowers make any payment of principal
with respect to any Eurodollar-based Advance or Quoted Rate Advance on any day other than the last
day of the Interest Period applicable thereto (whether voluntarily, pursuant to any mandatory
provisions hereof, by acceleration, or otherwise); (ii) Borrowers convert or refund (or attempt to
convert or refund) any such Advance on any day other than the last day of the Interest Period
applicable thereto (except as described in Section 2.5(e)); (iii) Borrowers fail to borrow, refund
or convert any Eurodollar-based Advance or Quoted Rate Advance after notice

104

 

has been given by
Borrowers to Agent in accordance with the terms hereof requesting such Advance; or (iv) or if any
Borrower fails to make any payment of principal in respect of a Eurodollar-based Advance or Quoted
Rate Advance when due, Borrowers shall reimburse Agent for itself and/or on behalf of any Lender,
as the case may be, within ten (10) Business Days of written demand therefor for any resulting
loss, cost or expense incurred (excluding the loss of any Applicable Margin) by Agent and Lenders,
as the case may be, as a result thereof, including, without limitation, any such loss, cost or
expense incurred in obtaining, liquidating, employing or redeploying deposits from third parties,
whether or not Agent and Lenders, as the case may be, shall have funded or committed to fund such
Advance. The amount payable hereunder by Borrowers to Agent for itself and/or on behalf of any
Lender, as the case may be, shall be deemed to equal an amount equal to the
excess, if any, of (a) the amount of interest which would have accrued on the amount so
prepaid, or not so borrowed, refunded or converted, for the period from the date of such prepayment
or of such failure to borrow, refund or convert, through the last day of the relevant Interest
Period, at the applicable rate of interest for said Advance(s) provided under this Agreement, over
(b) the amount of interest (as reasonably determined by Agent and Lenders, as the case may be)
which would have accrued to Agent and Lenders, as the case may be, on such amount by placing such
amount on deposit for a comparable period with leading banks in the interbank eurocurrency market.
Calculation of any amounts payable to any Lender under this paragraph shall be made as though such
Lender shall have actually funded or committed to fund the relevant Advance through the purchase of
an underlying deposit in an amount equal to the amount of such Advance and having a maturity
comparable to the relevant Interest Period; provided, however, that any Lender may fund any
Eurodollar-based Advance or Quoted Rate Advance, as the case may be, in any manner it deems fit and
the foregoing assumptions shall be utilized only for the purpose of the calculation of amounts
payable under this paragraph. Upon the written request of Borrowers, Agent and Lenders shall
deliver to 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 Eurodollar Lending Office. For any Eurodollar Advance, if Agent or a Lender, as
applicable, shall designate a Eurodollar Lending Office which maintains books separate from those
of the rest of Agent or such Lender, Agent or such Lender, as the case may be, shall have the
option of maintaining and carrying the relevant Advance on the books of such Eurodollar Lending
Office.

     11.3 Circumstances Affecting Eurodollar-based Rate Availability. If, with respect to any
Eurodollar-Interest Period, Agent or the Majority Lenders (after consultation with Agent) shall
determine in good faith that, by reason of circumstances affecting the foreign exchange and
interbank markets generally, deposits in eurodollars or in any applicable Alternate Currency, as
the case may be, in the applicable amounts are not being offered to the Agent or such Lenders for
such Eurodollar-Interest Period, then Agent shall forthwith give notice thereof to Borrowers.
Thereafter, until Agent notifies Borrowers that such circumstances no longer exist, (i) the
obligation of Lenders to make Eurodollar-based Advances, and the right of Borrowers to convert an
Advance to or refund an Advance as a Eurodollar-based Advance, as the case may be, shall be
suspended, and (ii) effective upon the last day of each Eurodollar-Interest Period related to any
existing Eurodollar-based Advance, each such Eurodollar-based Advance shall automatically be
converted into a Prime-based Advance (without regard to satisfaction of any conditions to
conversion contained elsewhere herein).

105

 

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

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

	 	(a)	 	shall subject any of the Lenders (or any of their respective
Eurodollar Lending Offices) to any tax, duty or other charge with respect to
any Advance or shall change the basis of taxation of payments to any of the
Lenders (or any of their respective Eurodollar Lending Offices) of the
principal of or interest on any Advance or any other amounts due under this
Agreement in respect thereof (except for changes in the rate of tax on the
overall net income of any of the Lenders or any of their respective Eurodollar
Lending Offices); or
	 
	 	(b)	 	shall impose, modify or deem applicable any reserve (including,
without limitation, any imposed by the Board of Governors of the Federal
Reserve System), special deposit or similar requirement against assets of,
deposits with or for the account of, or credit extended by, any of the Lenders
(or any of their respective Eurodollar Lending Offices) or shall impose on any
of the Lenders (or any of their respective Eurodollar Lending Offices) or the
foreign exchange and interbank markets any other condition affecting any
Advance;

106

 

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

     11.6 Capital Adequacy and Other Increased Costs.

	 	(a)	 	If, after the date of this Agreement, the adoption or
introduction of, or any change in any applicable law, treaty, rule or
regulation (whether domestic or foreign) now or hereafter in effect and whether
or not presently applicable to any Lender or Agent, or any interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof, or compliance by any Lender or Agent
with any guideline, request or directive of any such authority (whether or not
having the force of law), including any risk based capital guidelines, affects
or would affect the amount of capital required to be maintained by such Lender
or Agent (or any corporation controlling such Lender or Agent) and such Lender
or Agent, as the case may be, determines that the amount of such capital is
increased by or based upon the existence of such Lender’s or Agent’s
obligations or Advances hereunder and such increase has the effect of reducing
the rate of return on such Lender’s or Agent’s (or such controlling
corporation’s) capital as a consequence of such obligations or Advances
hereunder to a level below that which such Lender or Agent (or such controlling
corporation) could have achieved but for such circumstances (taking into
consideration its policies with respect to capital adequacy) by an amount
deemed by such Lender or Agent to be material (collectively, “Increased
Costs”), then Agent or such Lender shall notify Borrowers, and thereafter
Borrowers shall pay to such Lender or Agent, as the case may be, within ten
(10) Business Days of written demand therefor from such Lender or Agent,
additional amounts sufficient to compensate such Lender or Agent (or such
controlling corporation) for any increase in the amount of capital and reduced
rate of return which such Lender or Agent reasonably determines to be allocable
to the existence of such Lender’s or Agent’s obligations or Advances hereunder.

107

 

	 	 	 	A statement setting forth the amount of such compensation, the methodology for
the calculation and the calculation thereof which shall
also be prepared in good faith and in reasonable detail by such Lender or
Agent, as the case may be, shall be submitted by such Lender or by Agent to
Borrowers, reasonably promptly after becoming aware of any event described
in this Section 11.6(a) and shall be conclusively presumed to be correct,
absent manifest error.

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

     11.7 Right of Lenders to Fund through Branches and Affiliates. Each Lender (including
without limitation the Swing Line Lender) may, if it so elects, fulfill its commitment as to any
Advance hereunder by designating a branch or Affiliate of such Lender to make such Advance;
provided that (a) such Lender shall remain solely responsible for the performances of its
obligations hereunder and (b) no such designation shall result in any material increased costs to
Borrowers, including without limitation, increased costs to Borrowers under Section 10.1.

     11.8 Mitigation of Obligations. If any Lender requests compensation under Section 11.6 or
11.7, or if the Borrowers are required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 13.13, then such Lender
shall use reasonable efforts to designate a different lending office for funding or booking its
Loans hereunder or to assign its rights and obligations hereunder to another of its offices,
branches or affiliates, if, in the sole judgment of such Lender, such designation or assignment (i)
would eliminate or reduce amounts payable under Sections 11.6, 11.7 or 13.13, as the case may be,
in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would
not otherwise be disadvantageous to such Lender. The Borrowers hereby agree to pay all costs and
expenses incurred by any Lender for actions taken pursuant to this Section 11.8.

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

	 	(a)	 	Such adjustments shall be given prospective effect only,
effective as to all Advances outstanding hereunder, the Applicable Fee
Percentage and the Letter of Credit Fee, upon the date of delivery of the
financial statements under Sections 7.1(a) and 7.1(b) hereunder and the
Covenant Compliance
Report under Section 7.2(a) hereof, in each case establishing applicability
of the appropriate adjustment and in each case with no retroactivity or
claw-back. In the event Borrowers shall fail timely to deliver such

108

 

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

	 	(b)	 	From the Effective Date until the required date of delivery
(or, if earlier, delivery) of the financial statements under Section 7.1(a) or
7.1(b) hereof, as applicable, and the Covenant Compliance Report under Section
7.2(a) hereof, for the fiscal quarter ending June 30, 2008, the Applicable
Margins and Applicable Fee Percentages shall be those set forth under the Level
IV column of the pricing matrix attached to this Agreement as Schedule 1.1.
Thereafter, Applicable Margins and Applicable Fee Percentages shall be based
upon the quarterly financial statements and Covenant Compliance Reports,
subject to recalculation as provided in Section 11.9(a) above.
	 
	 	(c)	 	Notwithstanding the foregoing, however, if, prior to the
Payment in Full of the Indebtedness, as a result of any restatement of or
adjustment to the financial statements of, prior to the Reorganization, Company
and any of its Subsidiaries, and after the Reorganization, Holdings and any of
its Subsidiaries (relating to the current or any prior fiscal period), or for
any other reason, Agent determines that the Applicable Margin and/or the
Applicable Fee Percentages as calculated by Borrowers as of any applicable date
of determination were inaccurate in any respect and a proper calculation
thereof would have resulted in different pricing for any fiscal period, then
(x) if the proper calculation thereof would have resulted in higher pricing for
any such period, Borrowers shall automatically and retroactively be obligated
to pay to Agent, promptly upon demand by Agent or the Majority Lenders, an
amount equal to the excess of the amount of interest and fees that should have
been paid for such period over the amount of interest and fees actually paid
for such period and, if the current fiscal period is affected thereby, the
Applicable Margin and/or the Applicable Fee Percentages for the current period
shall be adjusted based on such recalculation; and (y) if the proper
calculation thereof would have resulted in lower pricing for such period, Agent
and Lenders shall have no obligation to recalculate such interest or fees or to
repay any interest or fees to Borrowers.

     11.10 Availability of Alternate Currency. The Issuing Lender shall not be required to issue
any Letter of Credit in an Alternate Currency if, at any time prior to issuing such Letter of
Credit, the Issuing Lender (after
consultation with Agent) shall determine, in its sole discretion, that (i) deposits in the
applicable Alternate Currency in the amounts and maturities required to fund any draws under such
Letter of Credit will not be available to the Agent and the Lenders; (ii) a fundamental change has
occurred in the foreign exchange or interbank markets with respect to the applicable Alternate
Currency (including, without limitation, changes in national or

109

 

international financial, political
or economic conditions or currency exchange rates or exchange controls); or (iii) it has become
otherwise materially impractical for the Issuing Lender, as applicable, to issue Letters of Credit
and/or to fund draws under such Letters of Credit in the applicable Alternate Currency. The Agent
or the Issuing Lender, as the case may be, shall promptly notify the Borrower Representative of any
such determination.

12. AGENT.

     12.1 Appointment of Agent. Each Lender and the holder of each Note (if issued) irrevocably
appoints and authorizes the Agent to act on behalf of such Lender or holder under this Agreement
and the other Loan Documents and to exercise such powers hereunder and thereunder as are
specifically delegated to Agent by the terms hereof and thereof, together with such powers as may
be reasonably incidental thereto, including without limitation the power to execute or authorize
the execution of financing or similar statements or notices, and other documents. In performing its
functions and duties under this Agreement, the Agent shall act solely as agent of the Lenders and
does not assume and shall not be deemed to have assumed any obligation towards or relationship of
agency or trust with or for any Credit Party.

     12.2 Deposit Account with Agent or any Lender. Borrowers authorize Agent and each Lender,
in Agent’s or such Lender’s sole discretion, upon notice to Borrowers to charge its general deposit
account(s), if any, maintained with the Agent or such Lender for the amount of any principal,
interest, or Fees due under this Agreement or the Fee Letter when the same become due and payable
under the terms of this Agreement, the Fee Letter or the Notes.

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

110

 

taken or omitted to be taken
by it in good faith in accordance with the advice of such counsel, accountants or experts.

     12.4 Successor Agent. Agent may resign as such at any time upon at least thirty (30) days
prior notice to Borrowers and each of the Lenders. If Agent at any time shall resign or if the
office of Agent shall become vacant for any other reason, Majority Lenders shall, by written
instrument, appoint successor agent(s) (“Successor Agent”) satisfactory to such Majority Lenders
and, so long as no Default or Event of Default has occurred and is continuing, to Borrowers (which
approval shall not be unreasonably withheld or delayed); provided, however that any such successor
Agent shall be a bank or a trust company or other financial institution which maintains an office
in the United States, or a commercial bank organized under the laws of the United States or any
state thereof, or any Affiliate of such bank or trust company or other financial institution which
is engaged in the banking business, and shall have a combined capital and surplus of at least
$500,000,000. Such Successor Agent shall thereupon become the Agent hereunder, as applicable, and
Agent shall deliver or cause to be delivered to any successor agent such documents of transfer and
assignment as such Successor Agent may reasonably request. If a Successor Agent is not so appointed
or does not accept such appointment before the resigning Agent’s resignation becomes effective, the
resigning Agent may appoint a temporary successor to act until such appointment by the Majority
Lenders and, if applicable, Borrowers, is made and accepted, or if no such temporary successor is
appointed as provided above by the resigning Agent, the Majority Lenders shall thereafter perform
all of the duties of the resigning Agent hereunder until such appointment by the Majority Lenders
and, if applicable, 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 hereunder. Upon such succession of any such Successor Agent, the resigning Agent shall
be discharged from its duties and obligations, in its capacity as Agent hereunder, except for its
gross negligence or willful misconduct arising prior to its resignation hereunder, and the
provisions of this Article 12 shall continue in effect for the benefit of the resigning Agent in
respect of any actions taken or omitted to be taken by it while it was acting as Agent.

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

     12.6 Authority of Agent to Enforce This Agreement. Each Lender, subject to the terms and
conditions of this Agreement, grants the Agent full power and authority as attorney-in-fact to
institute and maintain actions, suits or proceedings for the collection and enforcement of any
Indebtedness outstanding under this Agreement or any other Loan Document and to file such proofs of
debt or other documents as may be necessary to have the claims of the Lenders allowed

111

 

in any
proceeding relative to any Credit Party, or their respective creditors or affecting their
respective properties, and to take such other actions which Agent considers to be necessary or
desirable for the protection, collection and enforcement of the Notes, this Agreement or the other
Loan Documents.

     12.7 Indemnification of Agent. The Lenders agree (which agreement shall survive the
expiration or termination of this Agreement) to indemnify the Agent and its Affiliates (to the
extent not reimbursed by Borrowers, but without limiting any obligation of Borrowers to make such
reimbursement), ratably according to their respective Weighted Percentages, from and against any
and all claims, damages, losses, liabilities, costs or expenses of any kind or nature whatsoever
(including, without limitation, reasonable fees and expenses of house and outside counsel) which
may be imposed on, incurred by, or asserted against the Agent and its Affiliates in any way
relating to or arising out of this Agreement, any of the other Loan Documents or the transactions
contemplated hereby or any action taken or omitted by the Agent and its Affiliates under this
Agreement or any of the Loan Documents; provided, however, that no Lender shall be liable for any
portion of such claims, damages, losses, liabilities, costs or expenses resulting from the Agent’s
or its Affiliate’s gross negligence or willful misconduct. Without limitation of the foregoing,
each Lender agrees to reimburse the Agent and its Affiliates promptly upon demand for its ratable
share of any reasonable out-of-pocket expenses (including, without limitation, reasonable fees and
expenses of house and outside counsel) incurred by the Agent and its Affiliates in connection with
the preparation, execution, delivery, administration, modification, amendment or enforcement
(whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of
rights or responsibilities under, this Agreement or any of the other Loan Documents, to the extent
that the Agent and its Affiliates are not reimbursed for such expenses by Borrowers, but without
limiting the obligation of Borrowers to make such reimbursement. Each Lender agrees to reimburse
the Agent and its Affiliates promptly upon demand for its ratable share of any amounts owing to the
Agent and its Affiliates by the Lenders pursuant to this Section, provided that, if the Agent or
its Affiliates are subsequently reimbursed by Borrowers for such amounts, they shall refund to the
Lenders on a pro rata basis the amount of any excess reimbursement. If the indemnity furnished to
the Agent and its Affiliates under this Section shall
become impaired as determined in the Agent’s reasonable judgment or Agent shall elect in its
sole discretion to have such indemnity confirmed by the Lenders (as to specific matters or
otherwise), Agent shall give notice thereof to each Lender and, until such additional indemnity is
provided or such existing indemnity is confirmed, the Agent may cease, or not commence, to take any
action. Any amounts paid by the Lenders hereunder to the Agent or its Affiliates shall be deemed to
constitute part of the Indebtedness hereunder.

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

112

 

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

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

     12.11 Collateral Matters.

     (a) The Agent is authorized on behalf of all the Lenders, without the necessity of any notice
to or further consent from the Lenders, 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 Lenders irrevocably authorize the Agent, in its reasonable discretion, to the full
extent set forth in the post-amble to Section 13.10 hereof, (1) to release or terminate any Lien
granted to or held by the Agent upon any Collateral (a) upon Payment in Full of all Indebtedness
payable under this Agreement and under any other Loan Document; (b) constituting property
(including, without limitation, Equity Interests in any Person) sold or to be sold or disposed of
as part of or in connection with any disposition (whether by sale, by merger or by any other form
of transaction and including the property of any Subsidiary that is disposed of as permitted
hereby) permitted in accordance with the terms of this Agreement; (c) constituting property in
which a Credit Party owned no interest at the time the Lien was granted or at any time thereafter;
or (d) if approved, authorized or ratified in writing by the Majority Lenders, or all the Lenders,
as the case may be, as provided in Section 13.10; (2) to subordinate

113

 

the Lien granted to or held by
Agent on any Collateral to any other holder of a Lien on such Collateral which is permitted by
Section 8.2(b) hereof; and (3) if all of the Equity Interests held by the Credit Parties in any
Person are sold or otherwise transferred to any transferee other than Holdings or a Subsidiary of
Holdings as part of or in connection with any disposition (whether by sale, by merger or by any
other form of transaction) permitted in accordance with the terms of this Agreement, to release
such Person from all of its obligations under the Loan Documents (including, without limitation,
under any Guaranty). Upon request by the Agent at any time, the Lenders 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 Agents in their Individual Capacities. Comerica Bank and its Affiliates, successors
and assigns shall each have the same rights and powers hereunder as any other Lender and may
exercise or refrain from exercising the same as though such Lender were not the Agent. Comerica
Bank and its Affiliates may (without having to account therefor to any Lender) accept deposits
from, lend money to, and generally engage in any kind of banking, trust, financial advisory or
other business with the Credit Parties as if such Lender were not acting as the Agent hereunder,
and may accept fees and other consideration therefor without having to account for the same to the
Lenders.

     12.13 Agent’s Fees. Until the Indebtedness has been Paid in Full, Borrowers shall pay to
the Agent, as applicable, any agency or other fee(s) set forth (or to be set forth from time to
time) in the
applicable Fee Letter on the terms set forth therein. The agency fees referred to in this
Section 12.13 shall not be refundable under any circumstances.

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

     12.15 No Reliance on Agent’s Customer Identification Program.

     (a) Each Lender acknowledges and agrees that neither such Lender, nor any of its Affiliates,
participants or assignees, may rely on the Agent to carry out such Lender’s, Affiliate’s,
participant’s or assignee’s customer identification program, or other obligations required or
imposed under or pursuant to the Patriot Act or the regulations thereunder, including the
regulations contained in 31 CFR 103.121 (as hereafter amended or replaced, the “CIP Regulations”),
or any other Anti-Terrorism Law, including any programs involving any of the following items
relating to or in connection with Holdings or any of its Subsidiaries, any of their respective
Affiliates or agents, the Loan Documents or the transactions hereunder: (i) any identify
verification procedures, (ii) any record keeping, (iii) any comparisons with government lists, (iv)
any customer notices or (v) any other procedures required under the CIP Regulations or such other
laws.

114

 

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

     12.16 Bulkley Capital. Each Lender hereby acknowledges that (a) Company has contracted by
separate written agreement with Bulkley Capital, L.P. (“Bulkley”) to assist Company, among other
things, in identifying and obtaining written commitments from prospective lenders in connection
with the facilities under this Agreement, (b) Bulkley is only acting at the request of and on
behalf of the
Company, and not Comerica Bank, and (c) Comerica Bank shall have no liability to Company, any
Lender or any other Person for any actions taken by Bulkley or any of its representatives in
respect of the transactions contemplated by this Agreement, or for any financial, evaluation or
other information or material delivered or statements made by Bulkley to Company, any Lender or any
other Person.

13. MISCELLANEOUS.

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

     13.2 Consent to Jurisdiction. Holdings, the Borrowers, the Agent and Lenders hereby
irrevocably submit to the non-exclusive jurisdiction of any United States Federal Court or Texas
state court sitting in Dallas, Texas in any action or proceeding arising out of or relating to this
Agreement or any of the Loan Documents and Holdings, the Borrowers, Agent and Lenders hereby
irrevocably agree that all claims in respect of such action or proceeding may be heard and
determined in any such United States Federal Court or Texas state court. Chapter 346 of the Texas
Finance Code (which regulates certain revolving credit loan accounts and revolving tri-party
accounts) does not apply to this Agreement or the Notes. Holdings and each Borrower irrevocably
consents to the service of any and all process in any such action or proceeding brought in any
court in or of the State of Texas by the delivery of copies of such process to it at the applicable
addresses specified on the signature page hereto or by certified mail directed to such address or
such other address as may be designated by it in a notice to the other parties that complies as to
delivery with the terms of Section 13.6. Nothing in this Section shall affect the right of the
Lenders and the Agent to serve process in any other manner permitted by law or limit the right of
the Lenders or the Agent (or any of them) to bring any such action or proceeding against any Credit
Party or any of their property in the courts with subject matter jurisdiction of any other
jurisdiction. Each Borrower irrevocably waives any objection to the laying of venue of any such
suit or proceeding in the above described courts.

115

 

     13.3 Law of Texas. This Agreement, the Notes and, the other Loan Documents shall be
governed by and construed and enforced in accordance with the laws of the State of Texas. 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. Agent, Lenders, Borrowers and any other parties to the Loan Documents intend to contract in
strict compliance with applicable usury law from time to time in effect. In furtherance thereof
such Persons stipulate and agree that none of the terms and provisions contained in the Loan
Documents shall ever be construed to create a contract to pay, for the use, forbearance or
detention of money, interest in excess of the maximum amount of interest permitted to be charged by
applicable law from time to time in effect. Neither Borrowers, any other party to the Loan
Documents nor any present or future guarantors, endorsers, or other Persons hereafter becoming
liable for payment of any Indebtedness shall ever be liable for unearned interest thereon or shall
ever be required to pay interest thereon in excess of the maximum amount that may be lawfully
contracted for, charged, or received under applicable law from time to time in effect, and the
provisions of this section shall control over all other provisions of the Loan Documents which may
be in conflict or apparent conflict herewith. Agent and Lenders expressly disavow any intention to
contract for, charge, or collect excessive unearned interest or finance charges in the event the
maturity of any Indebtedness is accelerated. If (a) the maturity of any Indebtedness is
accelerated for any reason, (b) any Indebtedness is prepaid and as a result any amounts held to
constitute interest are determined to be in excess of the legal maximum, or (c) Agent or any Lender
or any other holder of any or all of the Indebtedness shall otherwise collect moneys which are
determined to constitute interest which would otherwise increase the interest on any or all of the
Indebtedness to an amount in excess of that permitted to be charged by applicable law then in
effect, then all sums determined to constitute interest in excess of such legal limit shall,
without penalty, be promptly applied to reduce the then outstanding principal of the related
Indebtedness or, at such Lender’s or holder’s option, promptly returned to Borrowers or the other
payor thereof upon such determination. In determining whether or not the interest paid or payable,
under any specific circumstance, exceeds the maximum amount permitted under applicable law, Agent,
Lenders, Borrowers (and any other payors thereof) shall to the greatest extent permitted under
applicable Law, (i) characterize any non-principal payment as an expense, fee or premium rather
than as interest, (ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize,
prorate, allocate, and spread the total amount of interest throughout the entire contemplated term
of the instruments evidencing the Obligations in accordance with the amounts outstanding from time
to time thereunder and the maximum legal rate of interest from time to time in effect under
applicable law in order to lawfully contract for, charge, or receive the maximum amount of interest
permitted under applicable Law. In the event applicable Law provides for an interest ceiling under
Chapter 303 of the Texas Finance Code (the “Texas Finance Code”) as amended, for that day, the
ceiling shall be the “weekly ceiling” as defined in the Texas Finance Code, provided that if any
applicable Law permits greater interest, the Law permitting the greatest interest shall apply. As
used in this section the term “applicable law” means the laws of the State of Texas or the laws of
the United States of America, whichever laws allow the greater interest, as such laws now exist or
may be changed or amended or come into effect in the future.

116

 

     13.5 Closing Costs and Other Costs; Indemnification.

     (a) Borrowers shall pay or reimburse (a) Agent and its Affiliates for payment of, on demand,
all reasonable costs and expenses, including, by way of description and not limitation, reasonable
in-house and outside attorney fees and advances, appraisal and accounting fees, lien search fees,
and required travel costs, incurred by Agent and its Affiliates in connection with the commitment,
consummation and closing of the loans contemplated hereby, or in connection with
the administration or enforcement of this Agreement or the other Loan Documents (including the
obtaining of legal advice regarding the rights and responsibilities of the parties hereto) or any
refinancing or restructuring of the loans or Advances provided under this Agreement or the other
Loan Documents, or any amendment or modification thereof requested by Borrowers, and (b) Agent and
its Affiliates and each of the Lenders, as the case may be, for all stamp and other taxes and
duties payable or determined to be payable in connection with the execution, delivery, filing or
recording of this Agreement and the other Loan Documents and the consummation of the transactions
contemplated hereby, and any and all liabilities with respect to or resulting from any delay in
paying or omitting to pay such taxes or duties. Furthermore, all reasonable costs and expenses,
including without limitation attorney fees, incurred by Agent and its Affiliates and, after the
occurrence and during the continuance of an Event of Default, by the Lenders in revising,
preserving, protecting, exercising or enforcing any of its or any of the Lenders’ rights against
Borrowers or any other Credit Party, or otherwise incurred by Agent and its Affiliates and the
Lenders in connection with any Event of Default or the enforcement of the loans (whether incurred
through negotiations, legal proceedings or otherwise), including by way of description and not
limitation, such charges in any court or bankruptcy proceedings or arising out of any claim or
action by any person against Agent, its Affiliates, or any Lender which would not have been
asserted were it not for Agent’s or such Affiliate’s or Lender’s relationship with Borrowers
hereunder or otherwise, shall also be paid by Borrowers. All of said amounts required to be paid by
Borrowers hereunder and not paid forthwith promptly following demand, as aforesaid, shall bear
interest, from the date incurred to the date payment is received by Agent, at the Prime-based Rate,
plus two percent (2%).

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

     (c) Borrowers agree to defend, indemnify and hold harmless Agent and each Lender (and their
respective Affiliates), and their respective employees, agents, officers and directors from and
against any and all claims, demands, penalties, fines, liabilities, settlements, damages, costs or
expenses of whatever kind or nature (including without limitation, reasonable attorneys

117

 

and
consultants fees, investigation and laboratory fees, environmental studies required by Agent or any
Lender in connection with the violation of Hazardous Material Laws), court costs and litigation
expenses, arising out of or related to (i) the presence, use, disposal, release or threatened
release of any Hazardous Materials on, from or affecting any premises owned or occupied by any
Credit Party in violation of or the non-compliance with applicable Hazardous Material Laws, (ii)
any personal injury (including wrongful death) or property damage (real or personal) arising out of
or related to such Hazardous Materials, (iii) any lawsuit or other
proceeding brought or threatened, settlement reached or governmental order or decree relating
to such Hazardous Materials, (iv) the cost of removal of Hazardous Materials from any portion of
any premises owned or occupied by any Credit Party, (v) taking necessary precautions to protect
against the release of Hazardous Materials on or affecting any premises owned or occupied by any
Credit Party and/or (vi) complying or coming into compliance with all Hazardous Material Laws
(including the cost of any remediation or monitoring required in connection therewith) or any other
Requirement of Law; provided, however, that Borrowers shall have no obligations under this Section
13.5(c) with respect to claims, demands, penalties, fines, liabilities, settlements, damages, costs
or expenses to the extent arising as a result of the gross negligence or willful misconduct of the
Agent or such Lender, as the case may be. The obligations of Borrowers under this Section 13.5(c)
shall be in addition to any and all other obligations and liabilities Borrowers may have to Agent
or any of the Lenders at common law or pursuant to any other agreement.Notices.

	 	(a)	 	Except as expressly provided otherwise in this Agreement (and
except as provided in clause (b) below), 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 or by facsimile and addressed or delivered to it at

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 facsimile, shall be deemed given
when received. The 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, by 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.
Any notice given by the Agent or any Lender to Borrower Representative or any
Borrower shall be deemed to be a notice to all of the Credit Parties.

118

 

	 	(b)	 	Notices and other communications provided to the Agent and the
Lenders party hereto under this Agreement or any other Loan Document may be

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

     13.7 Further Action. Borrowers, 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 Borrowers and the
Lenders and their respective successors and assigns.

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

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

     (d) To the extent permitted under clause (c) hereof, each assignment by a Lender of all or any
portion of its rights and obligations hereunder and under the other Loan Documents, shall be
subject to the following terms and conditions:

119

 

	 	(i)	 	each such assignment shall be made on a pro
rata basis, and shall be in a minimum amount of the lesser of (x) Five
Million Dollars
($5,000,000) or such lesser amount as the Agent and Borrower shall
agree and (y) the entire remaining amount of assigning Lender’s
aggregate interest in the Revolving Credit (and participations in any
outstanding Letters of Credit) and the Term Loan; provided however
that, in the case of (x), after giving effect to such assignment, in
no event shall the entire remaining amount (if any) of assigning
Lender’s aggregate interest in the Revolving Credit (and
participations in any outstanding Letters of Credit) and the Term
Loan be less than $5,000,000; and
	 
	 	(ii)	 	the parties to any assignment shall execute and
deliver to Agent an Assignment Agreement substantially (as determined
by Agent) in the form attached hereto as Exhibit H (with appropriate
insertions acceptable to Agent), together with a processing and
recordation fee in the amount, if any, required as set forth in the
Assignment Agreement (provided however that such Lender need not
deliver an Assignment Agreement in connection with assignments to such
Lender’s Affiliates or to a Federal Reserve Bank).

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

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

     (e) Holdings, Borrowers and the Agent acknowledge that each of the Lenders may at any time and
from time to time, subject to the terms and conditions hereof, grant participations in such
Lender’s rights and obligations hereunder (on a pro rata basis only) and under the other Loan
Documents to any Person (other than a natural person or to a Borrower or any of

120

 

Borrower’s
Affiliates or Subsidiaries); provided that any participation permitted hereunder shall become
effective only upon registration of such participation on the Participant Register as
provided in Section 13.8(g), and any participation shall comply with all applicable laws and
shall be subject to a participation agreement that incorporates the following restrictions:

	 	(i)	 	such Lender shall remain the holder of its
Notes hereunder (if such Notes are issued), notwithstanding any such
participation;
	 
	 	(ii)	 	a participant shall not reassign or transfer,
or grant any sub-participations in its participation interest hereunder
or any part thereof; and
	 
	 	(iii)	 	such Lender shall retain the sole right and
responsibility to enforce the obligations of the Credit Parties
relating to the Notes and the other Loan Documents, including, without
limitation, the right to proceed against any Guarantors, or cause the
Agent to do so (subject to the terms and conditions hereof), and the
right to approve any amendment, modification or waiver of any provision
of this Agreement without the consent of the participant (unless such
participant is an Affiliate of such Lender), except for those matters
covered by Section 13.10(a) through (e) hereof (provided that a
participant may exercise approval rights over such matters only on an
indirect basis, acting through such Lender and the Credit Parties,
Agent and the other Lenders may continue to deal directly with such
Lender in connection with such Lender’s rights and duties hereunder).
Notwithstanding the foregoing, however, in the case of any
participation granted by any Lender hereunder, the participant shall
not have any rights under this Agreement or any of the other Loan
Documents against the Agent, any other Lender or any Credit Party;
provided, however that the participant may have rights against such
Lender in respect of such participation as may be set forth in the
applicable participation agreement and all amounts payable by the
Credit Parties hereunder shall be determined as if such Lender had not
sold such participation. Each such participant shall be entitled to
the benefits of Section 10.1(d) (subject to its compliance with Section
13) and Article 11 of this Agreement to the same extent as if it were a
Lender and had acquired its interest by assignment pursuant to clause
(d) of this Section, provided that such participant agrees to comply
with its obligations under Section 13.13 and no participant shall be
entitled to receive any greater amount pursuant to the provisions of
Section 10.1(d) or Article 11 than the issuing Lender would have been
entitled to receive in respect of the amount of the participation
transferred by such issuing Lender to such participant had no such
transfer occurred and each such participant shall also be entitled to
the benefits of Section 9.6 hereof as though it were a Lender, 

121

 

	 	 	 	provided
that such participant agrees to be subject to Section 10.3 hereof as
though it were a Lender.

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

     (g) (i) The Agent shall maintain at its principal office a copy of each Assignment Agreement
delivered to it and a register (the “Register”) for the recordation of the names and addresses of
the Lenders, the Percentages of such Lenders and the principal amount of each type of Advance owing
to each such Lender from time to time. The entries in the Register shall be conclusive evidence,
absent manifest error, and Borrowers, the Agent, and the Lenders may treat each Person whose name
is recorded in the Register as the owner of the Advances recorded therein for all purposes of this
Agreement. The Register shall be available for inspection by Borrowers or any Lender upon
reasonable notice to the Agent and a copy of such information shall be provided to any such party
on their prior written request. The Agent shall give prompt written notice to Borrowers of the
making of any entry in the Register or any change in such entry. Upon its receipt of a properly
completed Assignment Agreement in accordance with Section 13.8(d), Agent shall (A) promptly accept
such Assignment Agreement and (B) on the effective date determined pursuant thereto, record the
information contained therein in the Register and give prompt notice of such acceptance and
recordation to the Borrowers.

     (ii) In the case of any assignment to a Lender’s Affiliate or to a Federal Reserve Bank in
connection with which an Assignment Agreement is not delivered as permitted under Section 13.8, and
which assignment is not therefore reflected in the Register, the assigning Lender, acting solely
for this purpose as non-fiduciary agent of Borrowers (without any other obligations, liabilities or
responsibilities), shall maintain a comparable register on behalf of Borrowers. The comparable
register shall be available for inspection by Borrowers or the Agent at any reasonable time and
from time to time upon reasonable prior notice.

     (iii) In the case any Lender sells participations as described in Section 13.8(e), such
Lender, acting solely for this purpose as a non-fiduciary agent of Borrowers (without any other
obligations, liabilities or responsibilities), shall maintain a register on which it enters the
name of all Participants in the Indebtedness held by it (the “Participant Register”). The
Participant Register shall be available for inspection by Borrowers or the Agent at any time and
from time to time upon reasonable prior notice.

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

122

 

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

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

     13.10 Amendment and Waiver. No amendment or waiver of any provision of this Agreement or
any other Loan Document, nor consent to any departure by any Credit Party therefrom, shall in any
event be effective unless the same shall be in writing and signed by the Agent and the Majority
Lenders (or by the Agent at the written request of the Majority Lenders) or, if this Agreement
expressly so requires with respect to the subject matter thereof, by all Lenders (and, with respect
to any amendments to this Agreement or the other Loan Documents, by any Credit Party or the
Guarantors that are signatories thereto), and then such waiver or consent shall be effective only
in the specific instance and for the specific purpose for which given; provided,
however, that no amendment, waiver or consent shall, unless in writing and signed by the
Lender or Lenders affected thereby, do any of the following: (a) increase the stated amount of such
Lender’s commitment hereunder, (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, (d) except as expressly permitted hereunder or under the Collateral Documents,
release all or substantially all of the Collateral (provided that neither Agent nor any Lender
shall be prohibited thereby from proposing or participating in a consensual or nonconsensual
debtor-in-possession or similar financing), or release any material guaranty provided by any Person
in favor of Agent and the Lenders, provided however that Agent shall be entitled, without notice to
or any further action or consent of the Lenders, to release any Collateral which any Credit Party
is permitted to sell, assign or otherwise transfer in compliance with this Agreement or the other
Loan Documents or release any guaranty to the extent expressly permitted in this Agreement or any
of the other Loan Documents (whether in connection with the sale, transfer or other disposition of
the applicable Guarantor or otherwise), (e) terminate or modify any indemnity provided to the
Lenders hereunder or under the other Loan Documents, except as shall be otherwise expressly
provided in this Agreement or any other Loan Document, or (f) change the definitions of “Revolving
Credit Percentage”, “Term Loan Percentage”, “Weighted Percentage”, “Interest Periods”, “Majority
Lenders”, “Majority Revolving Credit Lenders”, “Majority Term Loan Lenders”, Sections 10.2 or 10.3
hereof or this Section 13.10; provided further, that notwithstanding the foregoing, the
definitions of “Borrowing Base”, “Eligible Accounts”, “Eligible Inventory” may be changed, and the
Revolving Credit Maturity Date may be postponed or extended, only with the consent of all of the
Revolving Credit Lenders; the Term Loan Maturity Date may be postponed or extended only with the
consent of all the Term Loan Lenders; provided further, that notwithstanding the foregoing,
any amendment or wavier of, or consent to any variation from, the mandatory prepayment provisions
in Section 4.8 of the Credit Agreement may be made with the consent of the Majority Term Loan
Lenders; provided further, that no amendment, waiver or consent shall, unless in a writing
signed by the Swing Line
Lender, do any of the following: (x) reduce the principal of, or interest on, the Swing

123

 

Line
Note or (y) postpone any date fixed for any payment of principal of, or interest on, the Swing Line
Note; provided further, that no amendment, waiver or consent shall, unless in a
writing signed by Issuing Lender affect the rights or duties of Issuing Lender under this Agreement
or any of the other Loan Documents and no amendment, waiver, or consent shall, unless in a writing
signed by the Agent affect the rights or duties of the Agent under this Agreement or any other Loan
Document. All references in this Agreement to “Lenders” or “the Lenders” shall refer to all
Lenders, unless expressly stated to refer to Majority Lenders (or the like).

     The Agent shall, upon the written request of Borrowers, execute and deliver to the Credit
Parties such documents as may be necessary to evidence (1) the release of any Lien granted to or
held by the Agent upon any Collateral: (a) upon Payment in Full of all Indebtedness payable under
this Agreement and under any other Loan Document; (b) which constitutes property (including,
without limitation, Equity Interests in any Person) sold or to be sold or disposed of as part of or
in connection with any disposition (whether by sale, by merger or by any other form of transaction
and including the property of any Subsidiary that is disposed of as permitted hereby) permitted in
accordance with the terms of this Agreement; (c) which constitutes property in which a Credit Party
owned no interest at the time the Lien was granted or at any time thereafter; or (d) if approved,
authorized or ratified in writing by the Majority Lenders, or all the Lenders, as the case may be,
as provided in this Section 13.10; or (2) the release of any Person from its obligations under the
Loan Documents (including without limitation the Guaranty) if all of the Equity Interests of such
Person that were held by a Credit Party are sold or otherwise transferred to any transferee other
than Holdings or a Subsidiary of Holdings as part of or in connection with any disposition (whether
by sale, by merger or by any other form of transaction) permitted in accordance with the terms of
this Agreement; provided that (i) Agent shall not be required to execute any such release
or subordination agreement under clauses (1) or (2) above on terms which, in the Agent’s opinion,
would expose the Agent to liability or create any obligation or entail any consequence other than
the release of such Liens without recourse or warranty or such release shall not in any manner
discharge, affect or impair the Indebtedness or any Liens upon any Collateral retained by any
Credit Party, including (without limitation) the proceeds of the sale or other disposition, all of
which shall constitute and remain part of the Collateral.

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

124

 

regulation,
ruling or other requirement of law applicable to such Lender, and (e) to any prospective assignee
or participant in accordance with Section 13.8 hereof.

     13.12 Substitution of Lenders. If (a) any Lender has failed to fund its Revolving Credit
Percentage of any Revolving Credit Advance, or to fund a Revolving Credit Advance to repay a Swing
Line Advance or any Reimbursement Obligations, (b) the obligation of any Lender to make
Eurodollar-based Advances has been suspended pursuant to Section 11.3 or 11.4, (c) any Lender has
demanded compensation under Section 3.4(c), 11.5 or 11.6, (d) any Lender has not approved an
amendment, waiver or other modification of this Agreement, if such amendment or waiver has been
approved by the Majority Lenders and the consent of such Lender is required (in each case, an
“Affected Lender”), or (e) a Borrower is required to make additional payments to or on account of
Lender (or permitted assignee) under Section 10.1(d) solely as a result of a change in any law,
rule, regulation or treaty or in the administration, interpretation or application thereof by any
Governmental Authority that occurred after the date on which such Lender (or permitted assignee)
first became a party to this Agreement (and the assignment below shall result in a reduction in the
amount of the payments otherwise required to be made by the applicable Borrowers thereunder), then
the Agent or Borrowers shall have the right to make written demand on the Affected Lender (with a
copy to Borrowers in the case of a demand by the Agent or with a copy to the Agent in the case of a
demand by Borrowers) to assign and the Affected Lender shall assign, to one or more financial
institutions that comply with the provisions of Section 13.8 hereof (the “Purchasing Lender” or
“Purchasing Lenders”) to purchase the Advances of the Revolving Credit, Swing Line and/or the Term
Loan, as the case may be, of such Affected Lender (including, without limitation, its participating
interests in outstanding Swing Line Advances and Letters of Credit) and assume the commitment of
the Affected Lender to extend credit under the Revolving Credit (including without limitation its
obligation to purchase participations interest in Swing Line Advances and Letters of Credit) under
this Agreement. The Affected Lender shall be obligated to sell its Advances of the Revolving
Credit, Swing Line and/or the Term Loan, as the case may be, and assign its commitment to extend
credit under the Revolving Credit (including without limitation its obligations to purchase
participations in Swing Line Advances and Letters of Credit) to such Purchasing Lender or
Purchasing Lenders within ten (10) days after receiving notice from Borrowers requiring it to do
so, at an aggregate price equal to the outstanding principal amount thereof, plus unpaid interest
accrued thereon up to but excluding the date of the sale. In connection with any such sale, and as
a condition thereof, Borrowers shall pay to the Affected Lender all fees accrued for its account
hereunder to but excluding the date of such sale, plus, if demanded by the Affected Lender within
ten (10) Business Days after such sale, (i) the amount of any compensation which would be due to
the Affected Lender under Section 11.1 if Borrowers had prepaid the outstanding Eurodollar-based
Advances of the Affected Lender on the date of such sale and (ii) any additional compensation
accrued for its account under Sections 3.4(c), 11.5 and 11.6 to but excluding said date. Upon such
sale, the Purchasing Lender or Purchasing Lenders shall assume the Affected Lender’s commitment,
and the Affected Lender shall be released from its obligations hereunder to a corresponding extent.
If any Purchasing Lender is not already one of the Lenders, the Affected Lender, as assignor, such
Purchasing Lender, as assignee, Borrowers and the Agent, shall enter into an Assignment Agreement
pursuant to Section 13.8 hereof, whereupon such Purchasing
Lender shall be a Lender party to this Agreement, shall be deemed to be an assignee hereunder
and shall have all the rights and obligations of a Lender with a Revolving Credit Percentage equal
to its ratable share of the then applicable Revolving Credit Aggregate Commitment and the

125

 

applicable Percentages of the Term Loan of the Affected Lender. In connection with any assignment
pursuant to this Section 13.12, Borrowers or the Purchasing Lender shall pay to the Agent the
administrative fee for processing such assignment referred to in Section 13.8.

     13.13 Withholding Taxes.

     (a) Non-U.S. Lenders. If any Lender (or assignee or participant permitted under
Section 13.8) is not a “united states person” within the meaning of Section 7701(a)(30) of the
Internal Revenue Code (a “Non-U.S. Lender”), such Non-U.S. Lender shall promptly (but in any event
prior to the initial payment of interest hereunder or prior to its accepting any assignment under
Section 13.8 hereof, as applicable) deliver to the Agent two properly completed and duly executed
copies of (i) Internal Revenue Service Form W-8BEN or any successor form claiming entitlement to
complete exemption from U.S. withholding tax on payments of interest to such Non-U.S. Lender, and
specifying the applicable tax treaty between the United States and the jurisdiction which provides
such complete exemption from withholding; (ii) Internal Revenue Service Form W-8ECI or any
successor form evidencing that the income to be received by such Non-U.S. Lender hereunder is not
subject to U.S. withholding tax because it is effectively connected with the conduct of a trade or
business in the United States; or (iii) such other evidence satisfactory to the Agent that payments
to such Non-U.S. Lender are exempt from United States income tax withholding. Alternatively, if
such Non-U.S. Lender is claiming an exemption from U.S. withholding tax under Internal Revenue Code
section 871(h) or 881(c), such Non-U.S. Lender (1) hereby represents and warrants that such
Non-U.S. Lender is (A) not a “bank” within the meaning of Internal Revenue Code section 881(c), (B)
not a “10 percent shareholder” within the meaning of Internal Revenue Code section 871(h)(3)(B) and
(C) not a controlled foreign corporation receiving interest from a related person within the
meaning of Internal Revenue Code section 864(d)(4); and (2) will, prior to the initial payment of
interest hereunder or prior to its accepting any assignment under Section 13.8 hereof, as
applicable, deliver to the Agent and the Borrower Representative two properly completed and duly
executed copies of Internal Revenue Service Form W-8BEN or any successor form certifying that such
Non-U.S. Lender is not a U.S. person and income received in connection herewith is not effectively
connected with the conduct of a U.S. trade or business.

     Notwithstanding the foregoing, a Non-U.S. Lender shall not be required to deliver to Agent the
aforesaid forms or other evidence with respect to Advances to Borrowers, if such Non-U.S. Lender
has assigned its entire interest hereunder (including its Revolving Credit Commitment Amount, any
outstanding Advances hereunder and participations in Letters of Credit issued hereunder and any
Notes issued to it by Borrowers), to an Affiliate which is incorporated under the laws of the
United States or a state thereof, and so notifies the Agent and such Affiliate complies with its
obligations, as an assignee that is not a Non-U.S. person, under Section 13.13(b). Each Non-U.S.
Lender shall promptly amend or supplement any such forms or evidence as required to insure that
such forms or evidence are accurate, complete and non-misleading at all times, and upon the
obsolescence or invalidity of any form previously delivered by such Non-U.S. Lender shall promptly
deliver such new forms or evidence permitted under this Section 13.13(a) which establish that
payments to such Non-U.S. Lender continue to be
completely exempt from U.S. withholding tax. Promptly upon notice from the Agent of any
determination by the Internal Revenue Service that any payments previously made to any Non-U.S.
Lender hereunder were subject to United States income tax withholding when made, such

126

 

Non-U.S.
Lender shall pay to the Agent the excess of the aggregate amount required to be withheld from such
payments over the aggregate amount actually withheld by the Agent, and Agent shall, at its option,
remit such amount to the Internal Revenue Service in payment of such obligation or deliver such
amount to Borrower for payment of same. In addition, from time to time upon the reasonable request
of Borrowers, each Non-U.S. Lender and the Agent shall (to the extent it is able to do so based
upon applicable facts and circumstances), complete and provide Borrowers with such other forms,
certificates or other documents as may be reasonably necessary to allow 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.

     (b) U.S. Lenders. Any Lender (or assignee or participant permitted under Section
13.8) that is not a Non-U.S. Lender shall promptly (but in any event prior to the initial payment
of interest hereunder or prior to its accepting any assignment under Section 13.8 hereof, as
applicable) deliver to the Agent and the Borrower Representative (i) two properly completed and
duly executed copies of Internal Revenue Service Form W-9, or any subsequent versions thereof or
successors thereto, certifying that such Lender (or assignee or participant permitted under Section
13.8) is entitled to receive any and all payments in connection herewith free and clear from U.S.
withholding taxes and (ii) such other reasonable documentation as will enable Borrowers to
determine that such Lender (or assignee or participant permitted under Section 13.8) is not subject
to backup withholding and whether or not payments to such Lender (or assignee or participant
permitted under Section 13.8) are subject to any information reporting requirements.

     13.14 Taxes and Fees. Except as provided in Section 10.1(d), should any Tax or Other Taxes
become payable by a Lender or Agent (including without limitation the Swing Line Lender and the
Issuing Lender), Borrowers shall hold the Agent and such Lenders harmless with respect thereto,
together with any interest or penalties thereon arising from a Borrower’s actions or omissions,
provided, however, that Borrowers shall not be responsible for any such interest or penalties which
were incurred prior to the date that notice is given to the Credit Parties of such tax or fees.
Notwithstanding the foregoing, nothing contained in this Section 13.14 shall affect or reduce the
rights of any Lender or the Agent under Section 11.5 hereof.

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

127

 

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

     13.17 Complete Agreement; Conflicts. THIS AGREEMENT AND THE OTHER “LOAN AGREEMENTS” (AS
DEFINED IN SECTION 26.02(A)(2) OF THE TEXAS BUSINESS & COMMERCE CODE, AS AMENDED) REPRESENT THE
FINAL AGREEMENT BETWEEN THE PARTIES, AND THIS AGREEMENT AND THE OTHER WRITTEN LOAN AGREEMENTS MAY
NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS BETWEEN THE
PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES. In the event of any conflict
between the terms of this Agreement and the other Loan Documents, this Agreement shall govern.

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

     13.19 Table of Contents and Headings; Section References. The table of contents and the
headings of the various subdivisions hereof are for convenience of reference only and shall in no
way modify or affect any of the terms or provisions hereof and references herein to “sections,”
“subsections,” “clauses,” “paragraphs,” “subparagraphs,” “exhibits” and “schedules” shall be to
sections, subsections, clauses, paragraphs, subparagraphs, exhibits and schedules, respectively, of
this Agreement unless otherwise specifically provided herein or unless the context otherwise
clearly indicates.

     13.20 Construction of Certain Provisions. If any provision of this Agreement or any of the
Loan Documents refers to any action to be taken by any Person, or which such Person is prohibited
from taking, such provision shall be applicable whether such action is taken directly or indirectly
by such Person, whether or not expressly specified in such provision.

     13.21 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.

128

 

     13.22 Electronic Transmissions.

	 	(a)	 	Each of the Agent, the Credit Parties, the Lenders, and each of
their Affiliates is authorized (but not required) to transmit, post or
otherwise make or communicate, in its sole discretion, Electronic Transmissions
in connection with any Loan Document and the transactions contemplated therein.
Borrowers and each other Credit Party hereby acknowledges and agrees that the
use of Electronic Transmissions is not necessarily secure and that there are
risks associated with such use, including risks of interception, disclosure and
abuse and each indicates it assumes and accepts such risks by hereby
authorizing the transmission of Electronic Transmissions.
	 
	 	(b)	 	All uses of an E-System shall be governed by and subject to, in
addition to Section 13.6 and this Section 13.22, separate terms and conditions
posted or referenced in such E-System and related contractual obligations
executed by the Agent, the Credit Parties and the Lenders in connection with
the use of such E-System.
	 
	 	(c)	 	All E-Systems and Electronic Transmissions shall be provided
“as is” and “as available”. None of the Agent or any of its Affiliates
warrants the accuracy, adequacy or completeness of any E-Systems or Electronic
Transmission, and each disclaims all liability for errors or omissions therein.
No warranty of any kind is made by the Agent or any of its Affiliates in
connection with any E Systems or Electronic Transmission, including any
warranty of merchantability, fitness for a particular purpose, non-infringement
of third-party rights or freedom from viruses or other code defects. The
Agent, the Credit Parties and the Lenders agree that the Agent has no
responsibility for maintaining or providing any equipment, software, services
or any testing required in connection with any Electronic Transmission or
otherwise required for any E-System.

     13.23 Advertisements. The Agent and the Lenders may disclose the names of the Credit
Parties and the existence of the Indebtedness in general advertisements and trade publications or
otherwise, but only with the consent of the Borrower Representative (such consent not to be
unreasonably withheld or delayed).

     13.24 Reliance on and Survival of Provisions. All terms, covenants, agreements,
representations and warranties of the Credit Parties 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 any Credit Party in connection with this Agreement or any of the Loan
Documents shall be deemed to have been relied upon by the Lenders, notwithstanding any
investigation heretofore or hereafter made by any Lender or on such Lender’s behalf, and those
covenants and agreements of Holdings and Borrowers set forth in Section 13.5 hereof (together with
any other indemnities of any Credit Party contained elsewhere in this Agreement or in any of the
other Loan Documents) and of Lenders set forth in Section 12.7 hereof shall survive the Payment in
Full of the Indebtedness.

129

 

     13.25 Joint and Several Liability.

	 	(a)	 	Each of 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. 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 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 Lender 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 or Holdings)
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 Borrowers hereby waives 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,
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 Lender 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.

130

 

	 	(b)	 	Each of 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 Lender 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;
	 
	 	(c)	 	Each of Borrowers hereby expressly waives: (i) notice of the
Lenders’ 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; (iv) any claim or defense based on an election of
remedies; and (v) 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.
	 
	 	(d)	 	No delay on any of the Lenders 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 Lenders 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 Lenders permitted hereunder shall in any way affect or
impair any such Lenders’ rights or any Borrower’s Indebtedness under this
Agreement.
	 
	 	(e)	 	Each of Borrowers hereby represents and warrants to each of the
Lenders that it now has and will continue to have independent means of
obtaining information concerning Borrowers’ affairs, financial condition and
business. Lenders 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 Lenders’
possession.
	 
	 	(f)	 	Each of Borrowers represents and warrants (i) that the business
operations of Borrowers are interrelated and that the business operations of
Borrowers 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 the other credit facilities extended hereunder will directly or
indirectly benefit Borrowers hereunder, severally and jointly, regardless of
which Borrower receives part or all of the proceeds of such Advances.
	 
	 	(g)	 	Notwithstanding anything to the contrary contained herein, it
is the intention of Borrowers, Agent and the Lenders that the amount of the

131

 

	 	 	 	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 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 Borrowers’ respective obligations
hereunder shall be limited to the largest amount which, after giving effect
thereto, would not, under Applicable Insolvency Laws, render such Borrower’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 13.25(g), then
the amount of such excess shall, from and after the time of payment by
Borrowers (or any of them), be reimbursed by the Lenders upon demand by such
Borrowers. The foregoing proviso is intended solely to preserve the rights of
the Agent and the Lenders hereunder against 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
13.25(g) that would not otherwise be available under Applicable Insolvency
Laws.

     13.26 Judgment Currency. If for the purpose of obtaining a judgment in any court it is
necessary to convert any amount owing or payable to the Agent or any Lender under this Agreement
from the Alternate Currency in which it is due into a particular currency (the “Judgment
Currency”), the rate of exchange applied in that conversion shall be that at which the Agent, in
accordance with its normal procedures, could purchase the Alternate Currency with the Judgment
Currency at or about noon on the Business Day immediately preceding the date on which judgment is
given. The obligation of the Borrowers in respect of any amount owing or payable under this
Agreement to the Agent or any Lender in the Alternate Currency shall, notwithstanding any judgment
and payment in the Judgment Currency, be satisfied only to the extent that the Agent, in accordance
with its normal procedures, could purchase the Alternate Currency with the amount of the Judgment
Currency so paid at or about noon on the next Business Day following that payment; and if the
amount of the Alternate Currency which the Agent could so purchase is less than the amount
originally due in the Alternate Currency, the Borrowers shall, as a separate obligation and
notwithstanding the judgment or payment, indemnify the agent or the applicable Lender against any
loss.

14. GUARANTY OF HOLDINGS.

     14.1 Guaranty. Holdings hereby guarantees to the Lenders the due and punctual payment to
the Lenders when due, whether by acceleration or otherwise, of all of the Indebtedness hereunder
and Holdings hereby agrees that if Borrowers shall fail to pay any of the Indebtedness when and as
the same shall be due and payable, or shall fail to perform and

132

 

discharge any covenant,
representation or warranty in accordance with the terms of this Agreement, the Notes, the Letter of
Credit Agreements or any of the other Loan Documents (subject, in each case, to any applicable
periods of grace or cure), Holdings will forthwith pay to the Agent, on behalf of the Lenders, an
amount equal to any such amount or cause Borrowers to do so, and will pay any and all damages that
may be incurred or suffered in consequence thereof by the Agent or any of the Lenders and all
reasonable expenses, including reasonable attorneys’ fees, that may be incurred by the Agent or the
Lenders in enforcing such covenant, representation or warranty of Borrowers, and in enforcing the
covenants and agreements of this Guaranty.

     14.2 Unconditional Character of the Guaranty. The obligations of Holdings under this
Article shall be absolute and unconditional, and shall be a guaranty of payment and not of
collection, irrespective of the validity, regularity or enforceability of this Agreement, the
Notes, the Letter of Credit Agreements, the Letters of Credit, or any of the other Loan Documents,
or any provision thereof, the absence of any action to enforce the same, any waiver or consent with
respect to or any amendment of any provision thereof (provided that any amendment of this Article
shall be in accordance with the terms hereof), the recovery of any judgment against any Person or
action to enforce the same, any failure or delay in the enforcement of the obligations of Borrowers
under this Agreement, the Notes, the Letter of Credit Agreements, or any of the other Loan
Documents, or any setoff, counterclaim, recoupment, limitation, defense (other than the defense of
payment in full of the
Indebtedness) or termination whether with or without notice to Holdings. It is the intention
of the parties that the obligations of the Holdings under this Section 5 shall be absolute,
unconditional and irrevocable irrespective of:

	 	(a)	 	any lack of validity, legality or enforceability of this
Agreement or any Note, as the case may be;
	 
	 	(b)	 	the failure of any Lender or any holder of any Note:

	 	(i)	 	to enforce any right or remedy against any
Borrower or any other Person (including any Guarantor) under the
provisions of this Agreement, such Note, or otherwise, or
	 
	 	(ii)	 	to exercise any right or remedy against any
Guarantor of, or collateral securing, any Indebtedness;

	 	(c)	 	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;
	 
	 	(d)	 	any reduction, limitation, impairment or termination of any
Indebtedness with respect to any Borrower, for any reason, including any claim
of waiver, release, surrender, alteration or compromise, and shall not be
subject to (and Holdings hereby waives 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, 

133

 

	 	 	 	unenforceability of, or
any other event or occurrence affecting, any Indebtedness of any Borrower;

	 	(e)	 	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 Lender or any holder of
the Notes securing any of the Indebtedness; or
	 
	 	(f)	 	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, any surety or
any Guarantor.

     14.3 Reinstatement. Holdings agrees that its obligations 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 Lender or any holder of any Note,
upon the insolvency, bankruptcy or reorganization of any Borrower as though such payment had not
been made.

     14.4 Waiver of Defenses. Holdings hereby expressly waives: (i) notice of the Lenders’
acceptance of this Agreement; (ii) notice of the existence or creation or non payment of all or any
of the Indebtedness; (iii) presentment, demand, notice of dishonor, protest, and all other notices
whatsoever; 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. No delay on the part of any of the Lenders in the exercise of any right or remedy
shall operate as a waiver thereof, and no single or partial exercise by any of the Lenders 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 Lenders permitted hereunder shall in any way affect or impair
any such Lenders’ rights or Holdings’ obligations under this Agreement. Until all of the
Indebtedness has been Paid in Full, Holdings irrevocably and absolutely subordinates any and all
rights of subrogation, contribution, indemnification, recourse, reimbursement and any similar
rights against Borrowers, whether these rights arise under an express or implied contract or by
operation of law. It is the intention of the parties that, until all of the Indebtedness has been
Paid in Full, Holdings shall not be (or be deemed to be) a “creditor” (as defined in Section 101 of
the Federal Bankruptcy Code, as the same may be amended) of Borrowers (or any other Guarantor or
any other Person) by reason of the existence of this Agreement in the event that a Borrower becomes
a debtor in any proceeding under the Federal Bankruptcy Code. This waiver is given to induce
Lenders to enter into this Agreement and to extend the credit facilities to Borrowers. Holdings
waives any defense based upon or arising by reason of (a) any disability or other defense of any
Borrower or any other person; (b) the cessation or limitation from any cause, other than final and
irrevocable payment in full, of the Indebtedness; (c) any lack of authority of any officer,
director, partner, agent or any other person acting or purporting to act on behalf of a Borrower or
any defect in the formation of a Borrower; (d) the application by any Person of the proceeds of any
Indebtedness for purposes other than the purposes represented by Borrowers to Agent or Lenders or
intended or understood by Agent, Lenders or Holdings; (e) any act or omission by Agent or any
Lender which directly or indirectly results in or aids the discharge of a Borrower or any
Indebtedness by operation of law or otherwise; or (f) any modification of the

134

 

Indebtedness, in any
form, including without limit the renewal, extension, acceleration or other change in time for
payment of the Indebtedness, or other change in the terms of Indebtedness or any part of it,
including without limit an increase or decrease of the rate of interest. Holdings waives any
defense it may have based upon any election of remedies by Agent or any Lender which destroys its
subrogation rights or its right to proceed against a Borrower for reimbursement, including without
limit any loss of rights Holdings may suffer by reason of any rights, powers or remedies of a
Borrower in connection with any anti-deficiency laws or any other laws limiting, qualifying or
discharging the Indebtedness. Without limiting the generality of the foregoing, the obligations of
Holdings under this Article 5, and the rights of Agent and Lenders to enforce the same, by
proceedings, whether by action at law, suit in equity or otherwise, shall not be in any way
affected to the extent permitted by applicable law, by (i) any insolvency, bankruptcy, liquidation,
reorganization, readjustment, composition, dissolution, winding up or other proceeding involving or
affecting a Borrower, any or all of the Guarantors, Holdings or any other Person including any
discharge of, or bar or stay against collecting, all or any of the Indebtedness in or as a result
of any such proceeding; (ii) any change in the ownership of any of the capital stock (or other
ownership interests) of a Borrower, Holdings, or any other party providing collateral or guarantees
for any Indebtedness of Borrowers, or any of its
Affiliates; (iii) the election by Agent and Lenders, in any bankruptcy proceeding of any
person, to apply or not apply Section 1111(b)(2) of the Bankruptcy Code; (iv) any extension of
credit or the grant of any security interest or lien under Section 363 of the Bankruptcy Code; (v)
any agreement or stipulation with respect to the provision of adequate protection in any bankruptcy
proceeding of any person; (vi) the avoidance of any security interest or Lien in favor of Agent or
any Lender for any reason; (vii) any action taken by Agent or any Lender that is authorized by this
paragraph or any other provision of this Agreement or any Loan Document; or (viii) any other
principle or provision of law, statutory or otherwise, which is or might be in conflict with the
terms hereof. Holdings hereby waives to the fullest extent possible under applicable law, any
defense based upon the doctrine of marshaling of assets or upon an election of remedies by Agent
and the Lenders, including, without limitation, an election to proceeds by non-judicial rather than
judicial foreclosure, and any defense based upon any statute or rule of law which provides that the
obligation of a surety must be neither larger in amount nor in other respects more burdensome than
that of the principal.

     14.5 Representations, Warranties and Covenants. Holdings hereby represents and warrants to
each of the Lenders that it now has and will continue to have independent means of obtaining
information concerning Borrowers’ affairs, financial condition and business. Lenders shall not have
any duty or responsibility to provide Holdings with any credit or other information concerning
Borrowers’ affairs, financial condition or business which may come into the Lenders’ possession.
Holdings represents and warrants (i) that the business operations of Borrowers and Holdings are
interrelated and complement one another, and such entities have a common business purpose, (ii)
that, to permit the uninterrupted and continuous operations of Borrowers, such entities now require
and will from time to time hereafter require funds and credit accommodations for general business
purposes and (iii) that the proceeds of advances under the Revolving Credit, the Term Loan and
other credit facilities extended hereunder will directly or indirectly benefit Holdings regardless
of whether Holdings receives part or all of the proceeds of such Advances.
