II ADVANCES, PAYMENTS.

     2.1.  Revolving Advances.

          (a) Amount of Revolving Advances. Subject to the terms and conditions set forth in
this Agreement including Section 2.1(b), each Lender, severally and not jointly, will make
Revolving Advances to Borrower in aggregate amounts outstanding at any time equal to such Lender’s
Commitment Percentage of the lesser of (x) the Maximum Loan Amount or (y) an amount equal to the
sum of:

               (i) subject to the provisions of Section 2.1(b), up to 85% (the “Receivables Advance Rate”) of
Eligible Receivables, plus

               (ii) subject to the provisions of Section 2.1(b) hereof, up to the lesser of (A) 25% of the
lower of FIFO or market cost of Eligible Inventory, or (B) $12,500,000.00 in the aggregate at any
one time (“Inventory Advance Rate” and together with the Receivables

23

 

Advance Rate, collectively,
the “Advance Rates”), minus

               (iii) the lesser of (A) the aggregate Maximum Undrawn Amount of all outstanding trade Letters
of Credit and any outstanding Acceptances, or (B) the Letter of Credit Sublimit; minus

               (iv) such reserves as Agent may reasonably deem proper and necessary from time to time.

     The amount derived from the sum of (x) Sections 2.1(a)(y)(i) and(ii), minus (y)
Section 2.1 (a)(y)(iii and iv) at any time and from time to time shall be referred to as the
“Formula Amount”. The Revolving Advances shall be evidenced by one or more secured promissory
notes (collectively, the “Revolving Credit Note”) substantially in the form attached hereto
as Exhibit 2.1(a).

          (b) Discretionary Rights. The Advance Rates may be increased or decreased by Agent at
any time and from time to time in the exercise of its Permitted Discretion. Borrower consents to
any such increases or decreases and acknowledges that decreasing the Advance Rates or increasing or
imposing reserves may limit or restrict Advances requested by Borrowing Agent. The rights of Agent
under this subsection are subject to the provisions of Section 16.2(b). Notwithstanding anything
contained in this Agreement, no assets resulting from an acquisition described in Section 7.1(a)
shall be included in the Formula Amount until such time as Agent has performed an audit of such
assets, at which time Agent shall determine, in it sole discretion, whether to include such assets
in the Formula Amount.

     2.2. Procedure for Revolving Advances Borrowing.

          (a) Borrowing Agent may notify Agent prior to 10:00 a.m. on a Business Day of Borrower’s
request to incur, on that day, a Revolving Advance hereunder. Should any amount required to be
paid as interest hereunder, or as fees or other charges under this Agreement or any other agreement
with Agent or Lenders, or with respect to any other Obligation, become due, same shall be deemed a
request for a Revolving Advance as of the date such payment is due, in the amount required to pay
in full such interest, fee, charge or Obligation under this Agreement or any other agreement with
Agent or Lenders, and such request shall be irrevocable.

          (b) Notwithstanding the provisions of subsection (a) above, in the event Borrower desires to
obtain a Eurodollar Rate Loan, Borrowing Agent shall give Agent written notice by no later than
10:00 a.m. on the day which is three (3) Business Days prior to the date such Eurodollar Rate Loan
is to be borrowed, specifying (i) the date of the proposed borrowing (which shall be a Business
Day), (ii) the type of borrowing and the amount on the date of such Advance to be borrowed, which
shall be a minimum amount of $1,000,000.00 and in integral multiples of $100,000.00, and (iii) the
duration of the first Interest Period therefor. Interest Periods for Eurodollar Rate Loans shall
be for one, two, or three months; provided, if an Interest Period would end on a day that is not a
Business Day, it shall end on the next succeeding
Business Day unless such day falls in the next succeeding calendar month in which case the
Interest Period shall end on the next preceding Business Day. No Eurodollar Rate Loan shall be
made to Borrower during the continuance of an Event of Default.

24

 

          (c) Each Interest Period of a Eurodollar Rate Loan shall commence on the date such Eurodollar
Rate Loan is made and shall end on such date as Borrowing Agent may elect as set forth in
subsection (b)(iii) above provided that the exact length of each Interest Period shall be
determined in accordance with the practice of the interbank market for offshore Dollar deposits and
no Interest Period shall end after the last day of the Term.

     Borrowing Agent shall elect the initial Interest Period applicable to a Eurodollar Rate Loan
by its notice of borrowing given to Agent pursuant to Section 2.2(b) or by its notice of conversion
given to Agent pursuant to Section 2.2(d), as the case may be. Borrowing Agent shall elect the
duration of each succeeding Interest Period by giving irrevocable written notice to Agent of such
duration not later than 10:00 a.m. on the day which is three (3) Business Days prior to the last
day of the then current Interest Period applicable to such Eurodollar Rate Loan. If Agent does
not receive timely notice of the Interest Period elected by Borrowing Agent, Borrowing Agent shall
be deemed to have elected to convert to a Domestic Rate Loan subject to Section 2.2(d) hereinbelow.

          (d) Provided that no Event of Default shall have occurred and be continuing, Borrowing Agent
may, on the last Business Day of the then current Interest Period applicable to any outstanding
Eurodollar Rate Loan, or on any Business Day with respect to Domestic Rate Loans, convert any such
loan into a loan of another type in the same aggregate principal amount provided that any
conversion of a Eurodollar Rate Loan shall be made only on the last Business Day of the then
current Interest Period applicable to such Eurodollar Rate Loan. If Borrower desires to convert a
loan, Borrowing Agent shall give Agent written notice by no later than 10:00 a.m. (i) on the day
which is three (3) Business Days’ prior to the date on which such conversion is to occur with
respect to a conversion from a Domestic Rate Loan to a Eurodollar Rate Loan, or (ii) on the day
which is one (1) Business Day prior to the date on which such conversion is to occur with respect
to a conversion from a Eurodollar Rate Loan to a Domestic Rate Loan, specifying, in each case, the
date of such conversion, the loans to be converted and if the conversion is from a Domestic Rate
Loan to any other type of loan, the duration of the first Interest Period therefor.

          (e) At its option and upon written notice given prior to 10:00 a.m. (New York time) at least
three (3) Business Days’ prior to the date of such prepayment, Borrower may prepay the Eurodollar
Rate Loans in whole at any time or in part from time to time with accrued interest on the principal
being prepaid to the date of such repayment. Borrower shall specify the date of prepayment of
Advances which are Eurodollar Rate Loans and the amount of such prepayment. In the event that any
prepayment of a Eurodollar Rate Loan is required or permitted on a date other than the last
Business Day of the then current Interest Period with respect thereto, Borrower shall indemnify
Agent and Lenders therefor in accordance with Section 2.2(f) hereof.

          (f) Borrower shall indemnify Agent and Lenders and hold Agent and Lenders harmless from and
against any and all losses or expenses that Agent and Lenders may sustain or incur as a consequence
of any prepayment, conversion of or any default by Borrower in the
payment of the principal of or interest on any Eurodollar Rate Loan or failure by Borrower to
complete a borrowing of, a prepayment of or conversion of or to a Eurodollar Rate Loan after notice
thereof has been given, including, but not limited to, any interest payable by Agent or Lenders to
lenders of funds obtained by it in order to make or maintain its Eurodollar Rate Loans

25

 

hereunder.
A certificate as to any additional amounts payable pursuant to the foregoing sentence submitted by
Agent or any Lender to Borrowing Agent shall be conclusive absent manifest error.

          (g) Notwithstanding any other provision hereof, if any Applicable Law, treaty, regulation or
directive, or any change therein or in the interpretation or application thereof, shall make it
unlawful for any Lender (for purposes of this subsection (g), the term “Lender” shall include any
Lender and the office or branch where any Lender or any corporation or bank controlling such Lender
makes or maintains any Eurodollar Rate Loans) to make or maintain its Eurodollar Rate Loans, the
obligation of Lenders to make Eurodollar Rate Loans hereunder shall forthwith be suspended and
Borrower shall, if any affected Eurodollar Rate Loans are then outstanding, promptly upon request
from Agent, either pay all such affected Eurodollar Rate Loans or convert such affected Eurodollar
Rate Loans into loans of another type. If any such payment or conversion of any Eurodollar Rate
Loan is made on a day that is not the last day of the Interest Period applicable to such Eurodollar
Rate Loan, Borrower shall pay Agent, upon Agent’s request, such amount or amounts as may be
necessary to compensate Lenders for any loss or expense sustained or incurred by Lenders in respect
of such Eurodollar Rate Loan as a result of such payment or conversion, including (but not limited
to) any interest or other amounts payable by Lenders to lenders of funds obtained by Lenders in
order to make or maintain such Eurodollar Rate Loan. A certificate as to any additional amounts
payable pursuant to the foregoing sentence submitted by Lenders to Borrowing Agent shall be
conclusive absent manifest error.

     2.3. Disbursement of Advance Proceeds. All Advances shall be disbursed from whichever
office or other place Agent may designate from time to time and, together with any and all other
Obligations of Borrower to Agent or Lenders, shall be charged to Borrower’s Account on Agent’s
books. During the Term, Borrower may use the Revolving Advances by borrowing, prepaying and
reborrowing, all in accordance with the terms and conditions hereof. The proceeds of each
Revolving Advance requested by Borrowing Agent or deemed to have been requested by Borrowing Agent
under Section 2.2(a) hereof shall, with respect to requested Revolving Advances to the extent
Lenders make such Revolving Advances, be made available to Borrower on the day so requested by way
of credit to Borrower’s operating account at PNC, or such other bank as Borrowing Agent may
designate following notification to Agent, in immediately available federal funds or other
immediately available funds or, with respect to Revolving Advances deemed to have been requested by
Borrower, be disbursed to Agent to be applied to the outstanding Obligations giving rise to such
deemed request.

     2.4. Omitted.

     2.5. Maximum Advances. The aggregate balance of Advances outstanding at any time
shall not exceed the lesser of
(a) the Maximum Loan Amount or (b) the Formula Amount.

     2.6. Repayment of Advances.

          (a) The Advances shall be due and payable in full on the last day of the Term subject to
earlier prepayment as herein provided.

          (b) Borrower recognizes that the amounts evidenced by checks, notes, drafts

26

 

or any other items
of payment relating to and/or proceeds of Collateral may not be collectible by Agent on the date
received. In consideration of Agent’s agreement to conditionally credit Borrower’s Account as of
the Business Day on which Agent receives those items of payment, Borrower agrees that, in computing
the charges under this Agreement, all items of payment shall be deemed applied by Agent on account
of the Obligations after (i) the Business Day Agent receives such payments via wire transfer or
electronic depository check or (ii) in the case of payments received by Agent in any other form,
the Business Day such payment constitutes good funds in Agent’s account. Agent is not, however,
required to credit Borrower’s Account for the amount of any item of payment which is unsatisfactory
to Agent and Agent may charge Borrower’s Account for the amount of any item of payment which is
returned to Agent unpaid.

          (c) All payments of principal, interest and other amounts payable hereunder, or under any of
the Other Documents shall be made to Agent at the Payment Office not later than 1:00 P.M. (New York
time) on the due date therefor in lawful money of the United States of America in federal funds or
other funds immediately available to Agent. Agent shall have the right to effectuate payment on
any and all Obligations due and owing hereunder by charging Borrower’s Account or by making
Advances as provided in Section 2.2 hereof.

          (d) Borrower shall pay principal, interest, and all other amounts payable hereunder, or under
any related agreement, without any deduction whatsoever, including, but not limited to, any
deduction for any setoff or counterclaim.

     2.7. Repayment of Excess Advances. The aggregate balance of Advances outstanding at
any time in excess of the maximum amount of Advances permitted hereunder shall be immediately due
and payable without the necessity of any demand, at the Payment Office, whether or not a Default or
Event of Default has occurred.

     2.8. Statement of Account. Agent shall maintain, in accordance with its customary
procedures, a loan account (“Borrower’s Account”) in the name of Borrower in which shall be
recorded the date and amount of each Advance made by Agent and the date and amount of each payment
in respect thereof; provided, however, the failure by Agent to record the date and amount of any
Advance shall not adversely affect Agent or any Lender. Each month, Agent shall send to Borrowing
Agent a statement showing the accounting for the Advances made, payments made or credited in
respect thereof, and other transactions between Agent and Borrower, during such month. The monthly
statements shall be deemed correct and binding upon Borrower in the absence of manifest error and
shall constitute an account stated between Lenders and Borrower unless Agent receives a
written statement of Borrower’s specific exceptions thereto within thirty (30) days after such
statement is received by Borrowing Agent. The records of Agent with respect to the loan account
shall be conclusive evidence absent manifest error of the amounts of Advances and other charges
thereto and of payments applicable thereto.

     2.9. Letters of Credit and Acceptances. Subject to the terms and conditions hereof,
Agent shall (a) issue or cause the issuance of standby and/or trade Letters of Credit (“Letters of
Credit”) for the account of Borrower or (b) accept, or cause to be accepted Acceptances; provided,
however, that Agent will not be required to issue or cause to be issued any Letters of Credit or
accept or cause to be accepted any Acceptances to the extent that the issuance thereof

27

 

would then
cause the sum of (i) the outstanding Revolving Advances plus (ii) the Maximum Undrawn Amount of all
outstanding Letters of Credit plus (iii) outstanding Acceptances to exceed the lesser of (x) the
Maximum Loan Amount or (y) the Formula Amount. The Maximum Undrawn Amount of all outstanding
Letters of Credit shall not exceed in the aggregate at any time the Letter of Credit Sublimit. All
disbursements or payments related to Letters of Credit and Acceptances shall be deemed to be
Eurodollar Loans consisting of Revolving Advances and shall bear interest at the applicable
Revolving Interest Rate for Eurodollar Loans; Letters of Credit that have not been drawn upon shall
not bear interest.

     2.10. Issuance of Letters of Credit; Creation of Acceptances.

          (a) Borrowing Agent may request Agent to issue or cause the issuance of a Letter of Credit by
delivering to Agent, at the Payment Office, prior to 10:00 a.m. (New York time), at least five (5)
Business Days’ prior to the proposed date of issuance, Agent’s form of Letter of Credit Application
(the “Letter of Credit Application”) completed to the satisfaction of Agent; and, such
other certificates, documents and other papers and information as Agent may reasonably request.
Borrowing Agent also has the right to give instructions and make agreements with respect to any
application, any applicable letter of credit and security agreement, any applicable letter of
credit reimbursement agreement and/or any other applicable agreement, any letter of credit and the
disposition of documents, disposition of any unutilized funds, and to agree with Agent upon any
amendment, extension or renewal of any Letter of Credit.

          (b) Each Letter of Credit shall, among other things, (i) provide for the payment of sight
drafts, other written demands for payment, or acceptances of usance drafts when presented for honor
thereunder in accordance with the terms thereof and when accompanied by the documents described
therein and (ii) have an expiry date not later than twenty-four (24) months after such Letter of
Credit’s date of issuance and in no event later than the last day of the Term. Each standby Letter
of Credit shall be subject either to the Uniform Customs and Practice for Documentary Credits (1993
Revision), International Chamber of Commerce Publication No. 500, and any amendments or revision
thereof adhered to by the Issuer (“UCP 500”) or the International Standby Practices
(ISP98-International Chamber of Commerce Publication Number 590) (“ISP98 Rules”), as determined by
Agent, and each trade Letter of Credit shall be subject to UCP 500.

          (c) Agent shall use its reasonable efforts to notify Lenders of the request by Borrower for a
Letter of Credit or an Acceptance hereunder.

          (d) Agent shall have absolute discretion whether to accept any draft to create an Acceptance.
Without in any way limiting Agent’s absolute discretion whether to accept any draft, Borrower will
not present for acceptance any draft, and Agent will generally not accept any drafts (i) that arise
out of transactions involving the sale of goods by Borrower not in the Ordinary Course of Business,
(ii) that involve a sale to an Affiliate of Borrower, (iii) that involve any purchase for which
Agent has not received all related documents, instruments and forms requested by Agent, (iv) for
which Agent is unable to locate a purchaser in the ordinary course of business on standard terms,
or (v) that is not eligible for discounting with Federal Reserve Banks pursuant to paragraph 7 of
Section 13 of the Federal Reserve Act, as amended.

28

 

          (e) Subject to terms set by Agent from time to time in its discretion with respect to the
acceptance of drafts generally, Borrowing Agent may request Acceptances on any Business Day, by
delivering to Agent a written request for an Acceptance in a form acceptable to Agent, in its sole
discretion, and, promptly upon demand, copies of all invoices, delivery receipts and related
documents relating to that request that Agent might require. Provided that the request for
Acceptance is received prior to 10:30 a.m. and approved by Agent, Agent shall make the net proceeds
of the Acceptance available to Borrower by crediting the net amount of the Acceptance in lawful
money of the United States and in immediately available funds to Borrower’s Account. The net
amount of the Acceptance shall be calculated by discounting the Acceptance at the Banker’s
Acceptance Rate for the applicable maturity period upon the creation by Agent of an Acceptance..

          (f) Borrower shall pay to Agent the amount of any Acceptance on or before its maturity date.
In addition, Agent is hereby irrevocably authorized, in its sole discretion, to make Revolving
Advances from time to time, or to charge any account of Borrower, to pay any Acceptance for which
payment is due, or at any time after the occurrence of an Event of Default to fund cash collateral
for any outstanding Acceptance.

          (g) Each Acceptance shall be payable in Dollars and shall be in the face amount of at least
$1,000,000.00. The maturity of each Acceptance shall be in any 30 day increment equal to or
greater than 30 and less than or equal to 180 days or, if such day is not a Business Day, on the
next succeeding Business Day and, in any event, no later than the day preceding the expiration of
the Term. This Section 2.10(g) will not apply to Acceptances created under Letters of Credit.

     2.11. Requirements For Issuance of Letters of Credit and Acceptances.

          (a) Borrower shall authorize and direct any Issuer to name Borrower as the “Applicant” or
“Account Party” of each Letter of Credit. If Agent is not the Issuer of any Letter of Credit,
Borrower shall authorize and direct the Issuer to deliver to Agent all instruments, documents, and
other writings and property received by the Issuer pursuant to the Letter of Credit or any
Acceptance related thereto and to accept and rely upon Agent’s instructions and agreements with
respect to all matters arising in connection with the Letter of Credit, the application therefor or
any Acceptance therefor.

          (b) In connection with all Letters of Credit issued or caused to be issued by Agent under this
Agreement, Borrower hereby appoints Agent, or its designee, as its attorney, with full power and
authority if an Event of Default shall have occurred and is continuing, (i) to sign and/or endorse
Borrower’s name upon any warehouse or other receipts, letter of credit applications and acceptance,
(ii) to sign Borrower’s name on bills of lading; (iii) to clear Inventory through the United States
of America Customs Department (“Customs”) in the name of Borrower or Agent or Agent’s designee, and
to sign and deliver to Customs officials powers of attorney in the name of Borrower for such
purpose; and (iv) to complete in Borrower’s name or Agent’s, or in the name of Agent’s designee,
any order, sale or transaction, obtain the necessary documents in connection therewith, and collect
the proceeds thereof. Neither Agent nor its attorneys will be liable for any acts or omissions nor
for any error of judgment or mistakes of fact or law, except for Agent’s or its attorney’s willful
misconduct. This power, being

29

 

coupled with an interest, is irrevocable as long as any Letters of
Credit remain outstanding.

     2.12. Disbursements, Reimbursement.

          (a) Immediately upon the issuance of each Letter of Credit, each Lender shall be deemed to,
and hereby irrevocably and unconditionally agrees to, purchase from Agent a participation in such
Letter of Credit and each drawing thereunder in an amount equal to such Lender’s Commitment
Percentage of the Maximum Face Amount of such Letter of Credit and the amount of such drawing,
respectively.

          (b) In the event of any request for a drawing under a Letter of Credit by the beneficiary or
transferee thereof, Agent will promptly notify Borrower. Provided that it shall have received such
notice, Borrower shall reimburse (such obligation to reimburse Agent shall sometimes be referred to
as a “Reimbursement Obligation”) Agent prior to 12:00 Noon, New York time on each date that
an amount is paid by Agent under any Letter of Credit (each such date, a “Drawing Date”) in
an amount equal to the amount so paid by Agent. In the event Borrower fails to reimburse Agent for
the full amount of any drawing under any Letter of Credit by 12:00 Noon, New York time, on the
Drawing Date, Agent will promptly notify each Lender thereof, and Borrower shall be deemed to have
requested that a Domestic Rate Loan be made by the Lenders to be disbursed on the Drawing Date
under such Letter of Credit, subject to the amount of the unutilized portion of the lesser of
Maximum Revolving Advance Amount or the Formula Amount and subject to Section 8.2 hereof. Any
notice given by Agent pursuant to this Section 2.12(b) may be oral if immediately confirmed in
writing; provided that the lack of such an immediate confirmation shall not affect the
conclusiveness or binding effect of such notice.

          (c) Each Lender shall upon any notice pursuant to Section 2.12(b) make available to Agent an
amount in immediately available funds equal to its Commitment Percentage of the amount of the
drawing, whereupon the participating Lenders shall (subject to Section 2.12(d)) each be deemed to
have made a Domestic Rate Loan to Borrower in that amount. If any Lender so notified fails to make
available to Agent the amount of such Lender’s Commitment Percentage of such amount by no later
than 2:00 p.m., New York time on the Drawing Date, then interest shall accrue on such Lender’s
obligation to make such payment, from the Drawing Date to the date on which such Lender makes such
payment (i) at a rate per annum equal to the Federal Funds Rate during the first three days
following the Drawing Date and (ii) at a rate per annum equal to the rate applicable to Domestic
Rate Loans on and after the
fourth day following the Drawing Date. Agent will promptly give notice of the occurrence of
the Drawing Date, but failure of Agent to give any such notice on the Drawing Date or in sufficient
time to enable any Lender to effect such payment on such date shall not relieve such Lender from
its obligation under this Section 2.12(c), provided that such Lender shall not be obligated to pay
interest as provided in Section 2.12(c) (i) and (ii) until and commencing from the date of receipt
of notice from Agent of a drawing.

          (d) With respect to any unreimbursed drawing that is not converted into a Domestic Rate Loan
to Borrower in whole or in part as contemplated by Section 2.12(b), because of Borrower’s failure
to satisfy the conditions set forth in Section 8.2 (other than any notice requirements) or for any
other reason, Borrower shall be deemed to have incurred from Agent a borrowing (each a “Letter of
Credit Borrowing”) in the amount of such drawing. Such

30

 

Letter of Credit Borrowing shall be due and
payable on demand (together with interest) and shall bear interest at the rate per annum applicable
to a Domestic Rate Loan. Each Lender’s payment to Agent pursuant to Section 2.12(c) shall be
deemed to be a payment in respect of its participation in such Letter of Credit Borrowing and shall
constitute a “Participation Advance” from such Lender in satisfaction of its Participation
Commitment under this Section 2.12.

          (e) Each Lender’s Participation Commitment shall continue until the last to occur of any of
the following events: (x) Agent ceases to be obligated to issue or cause to be issued Letters of
Credit hereunder; (y) no Letter of Credit issued or created hereunder remains outstanding and
uncancelled and (z) all Persons (other than the Borrower) have been fully reimbursed for all
payments made under or relating to Letters of Credit.

     2.13. Repayment of Participation Advances. 

          (a) Upon (and only upon) receipt by Agent for its account of immediately available funds from
Borrower (i) in reimbursement of any payment made by the Agent under the Letter of Credit with
respect to which any Lender has made a Participation Advance to Agent, or (ii) in payment of
interest on such a payment made by Agent under such a Letter of Credit, Agent will pay to each
Lender, in the same funds as those received by Agent, the amount of such Lender’s Commitment
Percentage of such funds, except Agent shall retain the amount of the Commitment Percentage of such
funds of any Lender that did not make a Participation Advance in respect of such payment by Agent.

          (b) If Agent is required at any time to return to Borrower, or to a trustee, receiver,
liquidator, custodian, or any official in any insolvency proceeding, any portion of the payments
made by Borrower to Agent pursuant to Section 2.13(a) in reimbursement of a payment made under the
Letter of Credit or interest or fee thereon, each Lender shall, on demand of Agent, forthwith
return to Agent the amount of its Commitment Percentage of any amounts so returned by Agent plus
interest at the Federal Funds Effective Rate.

     2.14. Documentation. Borrower agrees to be bound by the terms of the Letter of Credit
Application and by Agent’s interpretations of any Letter of Credit or Acceptance issued or created
for Borrower’s account and by Agent’s written regulations and customary practices relating to
letters of credit,
though Agent’s interpretations may be different from Borrower’s own. In the event of a
conflict between the Letter of Credit Application and this Agreement, this Agreement shall govern.
It is understood and agreed that, except in the case of gross negligence or willful misconduct (as
determined by a court of competent jurisdiction in a final non-appealable judgment), Agent shall
not be liable for any error, negligence and/or mistakes, whether of omission or commission, in
following Borrower’s instructions or those contained in the Letters of Credit or any modifications,
amendments or supplements thereto.

     2.15. Determination to Honor Drawing Request. In determining whether to honor any
request for drawing under any Letter of Credit by the beneficiary thereof, Agent shall be
responsible only to determine that the documents and certificates required to be delivered under
such Letter of Credit have been delivered and that they comply on their face with the requirements
of such Letter of Credit and that any other drawing condition appearing on the face of such Letter
of Credit has been satisfied in the manner so set forth.

     2.16. Nature of Participation and Reimbursement Obligations. Each Lender’s obligation
in accordance with this Agreement to make the Revolving Advances or Participation Advances as a
result of a drawing under a Letter of Credit, and the obligations of Borrower to reimburse Agent
upon a draw under a Letter of Credit, shall be absolute, unconditional and irrevocable, and shall
be performed strictly in accordance with the terms of this Section 2.16 under all circumstances,
including the following circumstances:

          (a) any set-off, counterclaim, recoupment, defense or other right which such Lender may have
against Agent, Borrower or any other Person for any reason whatsoever;

          (b) the failure of Borrower or any other Person to comply, in connection with a Letter of
Credit Borrowing, with the conditions set forth in this Agreement for the making of a Revolving
Advance, it being acknowledged that such conditions are not required for the making of a Letter of
Credit Borrowing and the obligation of the Lenders to make Participation Advances under Section
2.12;

          (c) any lack of validity or enforceability of any Letter of Credit;

          (d) any claim of breach of warranty that might be made by Borrower or any Lender against the
beneficiary of a Letter of Credit, or the existence of any claim, set-off, recoupment,
counterclaim, crossclaim, defense or other right which Borrower or any Lender may have at any time
against a beneficiary, any successor beneficiary or any transferee of any Letter of Credit or the
proceeds thereof (or any Persons for whom any such transferee may be acting), Agent or any Lender
or any other Person, whether in connection with this Agreement, the transactions contemplated
herein or any unrelated transaction (including any underlying transaction between Borrower or any
Subsidiaries of Borrower and the beneficiary for which any Letter of Credit was procured);

          (e) the lack of power or authority of any signer of (or any defect in or forgery of any
signature or endorsement on) or the form of or lack of validity, sufficiency, accuracy,
enforceability or genuineness of any draft, demand, instrument, certificate or other document
presented under or in connection with any Letter of Credit, or any fraud or alleged fraud in
connection with any Letter of Credit, or the transport of any property or provisions of services
relating to a Letter of Credit, in each case even if Agent or any of Agent’s Affiliates has been
notified thereof;

          (f) payment by Agent under any Letter of Credit against presentation of a demand, draft or
certificate or other document which does not comply with the terms of such Letter of Credit;

          (g) the solvency of, or any acts or omissions by, any beneficiary of any Letter of Credit, or
any other Person having a role in any transaction or obligation relating to a Letter of Credit, or
the existence, nature, quality, quantity, condition, value or other characteristic of any property
or services relating to a Letter of Credit;

          (h) any failure by the Agent or any of Agent’s Affiliates to issue any Letter of Credit in the
form requested by Borrower, unless the Agent has received written notice from Borrower of such
failure within three (3) Business Days after the Agent shall have furnished

32

 

Borrower a copy of such
Letter of Credit and such error is material and no drawing has been made thereon prior to receipt
of such notice;

          (i) any Material Adverse Effect on Borrower;

          (j) any breach of this Agreement or any Other Document by any party thereto;

          (k) the occurrence or continuance of an insolvency proceeding with respect to Borrower;

          (l) the fact that a Default or Event of Default shall have occurred and be continuing;

          (m) the fact that the Term shall have expired or this Agreement or the Obligations hereunder
shall have been terminated; and

          (n) any other circumstance or happening whatsoever, whether or not similar to any of the
foregoing.

     2.17. Indemnity. In addition to amounts payable as provided in Section 16.5, the
Borrower hereby agrees to protect, indemnify, pay and save harmless Agent and any of Agent’s
Affiliates that have issued a Letter of Credit from and against any and all claims, demands,
liabilities, damages, taxes, penalties, interest, judgments, losses, costs, charges and expenses
(including reasonable fees, expenses and disbursements of counsel and allocated costs of internal
counsel) which the Agent or any of Agent’s Affiliates may incur or be subject to as a consequence,
direct or indirect, of the issuance of any Letter of Credit, other than as a result of (A) the
gross negligence or willful misconduct of the Agent as determined by a final and non-appealable
judgment of a court
of competent jurisdiction or (b) the wrongful dishonor by the Agent or any of Agent’s
Affiliates of a proper demand for payment made under any Letter of Credit, except if such dishonor
resulted from any act or omission, whether rightful or wrongful, of any present or future de jure
or de facto Governmental Body (all such acts or omissions herein called “Governmental Acts”).

     2.18. Liability for Acts and Omissions. As between Borrower and Agent and Lenders,
Borrower assumes all risks of the acts and omissions of, or misuse of the Letters of Credit by, the
respective beneficiaries of such Letters of Credit. In furtherance and not in limitation of the
respective foregoing, Agent shall not be responsible for: (i) the form, validity, sufficiency,
accuracy, genuineness or legal effect of any document submitted by any party in connection with the
application for an issuance of any such Letter of Credit, even if it should in fact prove to be in
any or all respects invalid, insufficient, inaccurate, fraudulent or forged (even if Agent shall
have been notified thereof); (ii) the validity or sufficiency of any instrument transferring or
assigning or purporting to transfer or assign any such Letter of Credit or the rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective
for any reason; (iii) the failure of the beneficiary of any such Letter of Credit, or any other
party to which such Letter of Credit may be transferred, to comply fully with any conditions
required in order to draw upon such Letter of Credit or any other claim of Borrower against any
beneficiary of such Letter of Credit, or any such transferee, or any dispute between or among

33

 

Borrower and any beneficiary of any Letter of Credit or any such transferee; (iv) errors,
omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable,
telegraph, telex or otherwise, whether or not they be in cipher; (v) errors in interpretation of
technical terms; (vi) any loss or delay in the transmission or otherwise of any document required
in order to make a drawing under any such Letter of Credit or of the proceeds thereof; (vii) the
misapplication by the beneficiary of any such Letter of Credit of the proceeds of any drawing under
such Letter of Credit; or (viii) any consequences arising from causes beyond the control of Agent,
including any governmental acts, and none of the above shall affect or impair, or prevent the
vesting of, any of Agent’s rights or powers hereunder. Nothing in the preceding sentence shall
relieve Agent from liability for Agent’s gross negligence or willful misconduct (as determined by a
court of competent jurisdiction in a final non-appealable judgment) in connection with actions or
omissions described in such clauses (i) through (viii) of such sentence. In no event shall Agent
or Agent’s Affiliates be liable to the Borrower for any indirect, consequential, incidental,
punitive, exemplary or special damages or expenses (including without limitation attorneys’ fees),
or for any damages resulting from any change in the value of any property relating to a Letter of
Credit.

     Without limiting the generality of the foregoing, Agent and each of its Affiliates (i) may
rely on any oral or other communication believed in good faith by Agent or such Affiliate to have
been authorized or given by or on behalf of the applicant for a Letter of Credit, (ii) may honor
any presentation if the documents presented appear on their face substantially to comply with the
terms and conditions of the relevant Letter of Credit; (iii) may honor a previously dishonored
presentation under a Letter of Credit, whether such dishonor was pursuant to a court order, to
settle or compromise any claim of wrongful dishonor, or otherwise, and shall be entitled to
reimbursement to the same extent as if such presentation had initially been honored, together with
any interest paid by Agent or its Affiliates; (iv) may honor any drawing that is payable upon
presentation of a statement advising negotiation or payment, upon receipt of such statement
(even if such statement indicates that a draft or other document is being delivered
separately), and shall not be liable for any failure of any such draft or other document to arrive,
or to conform in any way with the relevant Letter of Credit; (v) may pay any paying or negotiating
bank claiming that it rightfully honored under the laws or practices of the place where such bank
is located; and (vi) may settle or adjust any claim or demand made on Agent or its Affiliate in any
way related to any order issued at the applicant’s request to an air carrier, a letter of guarantee
or of indemnity issued to a carrier or any similar document (each an “Order”) and honor any drawing
in connection with any Letter of Credit that is the subject of such Order, notwithstanding that any
drafts or other documents presented in connection with such Letter of Credit fail to conform in any
way with such Letter of Credit.

     In furtherance and extension and not in limitation of the specific provisions set forth above,
any action taken or omitted by Agent under or in connection with the Letters of Credit issued by it
or any documents and certificates delivered thereunder, if taken or omitted in good faith and
without gross negligence (as determined by a court of competent jurisdiction in a final
non-appealable judgment), shall not put Agent under any resulting liability to Borrower or any
Lender.

     2.19. Additional Payments. Any sums expended by Agent or any Lender due to Borrower’s
failure to perform or comply with its obligations under this Agreement or any Other

34

 

Document
including Borrower’s obligations under Sections 4.2, 4.4, 4.12, 4.13, 4.14 and 6.1 hereof, may be
charged to Borrower’s Account as a Revolving Advance and added to the Obligations.

     2.20. Manner of Borrowing and Payment.

          (a) Each borrowing of Revolving Advances shall be advanced according to the applicable
Commitment Percentages of Lenders.

          (b) Each payment (including each prepayment) by Borrower on account of the principal of and
interest on the Revolving Advances, shall be applied to the Revolving Advances pro rata according
to the applicable Commitment Percentages of Lenders. Except as expressly provided herein, all
payments (including prepayments) to be made by Borrower on account of principal, interest and fees
shall be made without set off or counterclaim and shall be made to Agent on behalf of the Lenders
to the Payment Office, in each case on or prior to 1:00 P.M., New York time, in Dollars and in
immediately available funds.

          (c) Notwithstanding anything to the contrary contained in Sections 2.20(a) and (b) hereof,
commencing with the first Business Day following the Closing Date, each borrowing of Revolving
Advances shall be advanced by Agent and each payment by Borrower on account of Revolving Advances
shall be applied first to those Revolving Advances advanced by Agent. On or before 1:00 P.M., New
York time, on each Settlement Date commencing with the first Settlement Date following the Closing
Date, Agent and Lenders shall make certain payments as follows: (I) if the aggregate amount of new
Revolving Advances made by Agent during the preceding Week (if any) exceeds the aggregate amount of
repayments applied to outstanding Revolving Advances during such preceding Week, then each Lender
shall provide
Agent with funds in an amount equal to its applicable Commitment Percentage of the difference
between (w) such Revolving Advances and (x) such repayments and (II) if the aggregate amount of
repayments applied to outstanding Revolving Advances during such Week exceeds the aggregate amount
of new Revolving Advances made during such Week, then Agent shall provide each Lender with funds in
an amount equal to its applicable Commitment Percentage of the difference between (y) such
repayments and (z) such Revolving Advances.

          (d) Each Lender shall be entitled to earn interest at the applicable Revolving Interest Rate
on outstanding Advances which it has funded.

          (e) Promptly following each Settlement Date, Agent shall submit to each Lender a certificate
with respect to payments received and Advances made during the Week immediately preceding such
Settlement Date. Such certificate of Agent shall be conclusive in the absence of manifest error.

          (f) If any Lender or Participant (a “benefited Lender”) shall at any time receive any
payment of all or part of its Advances, or interest thereon, or receive any Collateral in respect
thereof (whether voluntarily or involuntarily or by set-off) in a greater proportion than any such
payment to and Collateral received by any other Lender, if any, in respect of such other Lender’s
Advances, or interest thereon, and such greater proportionate payment or receipt of Collateral is
not expressly permitted hereunder, such benefited Lender shall purchase for cash

35

 

from the other
Lenders a participation in such portion of each such other Lender’s Advances, or shall provide such
other Lender with the benefits of any such Collateral, or the proceeds thereof, as shall be
necessary to cause such benefited Lender to share the excess payment or benefits of such Collateral
or proceeds ratably with each of the other Lenders; provided, however, that if all or any portion
of such excess payment or benefits is thereafter recovered from such benefited Lender, such
purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such
recovery, but without interest. Each Lender so purchasing a portion of another Lender’s Advances
may exercise all rights of payment (including rights of set-off) with respect to such portion as
fully as if such Lender were the direct holder of such portion.

          (g) Unless Agent shall have been notified by telephone, confirmed in writing, by any Lender
that such Lender will not make the amount which would constitute its applicable Commitment
Percentage of the Advances available to Agent, Agent may (but shall not be obligated to) assume
that such Lender shall make such amount available to Agent on the next Settlement Date and, in
reliance upon such assumption, make available to Borrower a corresponding amount. Agent will
promptly notify Borrower of its receipt of any such notice from a Lender. If such amount is made
available to Agent on a date after such next Settlement Date, such Lender shall pay to Agent on
demand an amount equal to the product of (i) the daily average Federal Funds Rate (computed on the
basis of a year of 360 days) during such period as quoted by Agent, times (ii) such amount, times
(iii) the number of days from and including such Settlement Date to the date on which such amount
becomes immediately available to Agent. A certificate of Agent submitted to any Lender with
respect to any amounts owing under this paragraph (e) shall be conclusive, in the absence of
manifest error. If such amount is not in fact made available to Agent by such Lender within three
(3) Business Days after such Settlement Date, Agent shall be entitled to recover such an amount,
with interest thereon at the rate per annum then applicable to such Revolving Advances hereunder,
on demand from Borrower;
provided, however, that Agent’s right to such recovery shall not prejudice or otherwise
adversely affect Borrower’s rights (if any) against such Lender.

     2.21. Mandatory Prepayments. Subject to Section 4.3 and Section 7.1(b) hereof, when
Borrower sells or otherwise disposes of any Collateral other than Inventory in the Ordinary Course
of Business, Borrower shall repay the Advances in an amount equal to the net proceeds of such sale
(i.e., gross proceeds less the reasonable costs of such sales or other dispositions), such
repayments to be made promptly but in no event more than one (1) Business Day following receipt of
such net proceeds, and until the date of payment, such proceeds shall be held in trust for Agent.
The foregoing shall not be deemed to be implied consent to any such sale otherwise prohibited by
the terms and conditions hereof. Such repayments shall be to the remaining Advances in such order
as Agent may determine, subject to Borrower’s ability to reborrow Revolving Advances in accordance
with the terms hereof.

     2.22. Use of Proceeds.

          (a) Borrower shall apply the proceeds of Advances to (i) pay fees and expenses relating to
this transaction, and (ii) provide for its working capital needs and reimburse drawings under
Letters of Credit.

          (b) Without limiting the generality of Section 2.22(a) above, neither the

36

 

Borrower nor any
other Person which may in the future become party to this Agreement or the Other Documents as
Borrower, intends to use nor shall they use any portion of the proceeds of the Advances, directly
or indirectly, for any purpose in violation of the Trading with the Enemy Act.

     2.23. Defaulting Lender.

          (a) Notwithstanding anything to the contrary contained herein, in the event any Lender (x) has
refused (which refusal constitutes a breach by such Lender of its obligations under this Agreement)
to make available its portion of any Advance or (y) notifies either Agent or Borrower that it does
not intend to make available its portion of any Advance (if the actual refusal would constitute a
breach by such Lender of its obligations under this Agreement) (each, a “Lender Default”),
all rights and obligations hereunder of such Lender (a “Defaulting Lender”) as to which a
Lender Default is in effect and of the other parties hereto shall be modified to the extent of the
express provisions of this Section 2.23 while such Lender Default remains in effect.

          (b) Advances shall be incurred pro rata from Lenders (the “Non-Defaulting Lenders”)
which are not Defaulting Lenders based on their respective Commitment Percentages, and no
Commitment Percentage of any Lender or any pro rata share of any Advances required to be advanced
by any Lender shall be increased as a result of such Lender Default. Amounts received in respect
of principal of any type of Advances shall be applied to reduce the applicable Advances of each
Lender pro rata based on the aggregate of the outstanding Advances of that type of all Lenders at
the time of such application; provided, that, such amount shall not be applied to any Advances of a
Defaulting Lender at any time when, and to the extent that, the aggregate amount of Advances of any
Non-Defaulting Lender exceeds such Non-Defaulting
Lender’s Commitment Percentage of all Advances then outstanding.

          (c) A Defaulting Lender shall not be entitled to give instructions to Agent or to approve,
disapprove, consent to or vote on any matters relating to this Agreement and the Other Documents.
All amendments, waivers and other modifications of this Agreement and the Other Documents may be
made without regard to a Defaulting Lender and, for purposes of the definition of “Required
Lenders”, a Defaulting Lender shall be deemed not to be a Lender and not to have Advances
outstanding.

          (d) Other than as expressly set forth in this Section 2.23, the rights and obligations of a
Defaulting Lender (including the obligation to indemnify Agent) and the other parties hereto shall
remain unchanged. Nothing in this Section 2.23 shall be deemed to release any Defaulting Lender
from its obligations under this Agreement and the Other Documents, shall alter such obligations,
shall operate as a waiver of any default by such Defaulting Lender hereunder, or shall prejudice
any rights which Borrower, Agent or any Lender may have against any Defaulting Lender as a result
of any default by such Defaulting Lender hereunder.

          (e) In the event a Defaulting Lender retroactively cures to the satisfaction of Agent the
breach which caused a Lender to become a Defaulting Lender, such Defaulting Lender shall no longer
be a Defaulting Lender and shall be treated as a Lender under this Agreement.

III INTEREST AND FEES.

37

 

     3.1. Interest. Interest on Advances shall be payable in arrears on the first day of
each month with respect to Domestic Rate Loans and, with respect to Eurodollar Rate Loans, at the
end of each Interest Period or, for Eurodollar Rate Loans with an Interest Period in excess of
three months, at the earlier of (a) each three months from the commencement of such Eurodollar Rate
Loan or (b) the end of the Interest Period. Interest charges shall be computed on the actual
principal amount of Advances outstanding during the month at a rate per annum equal to the
applicable Revolving Interest Rate. Whenever, subsequent to the date of this Agreement, the Base
Rate is increased or decreased, the applicable Revolving Interest Rate shall be similarly changed
without notice or demand of any kind by an amount equal to the amount of such change in the Base
Rate during the time such change or changes remain in effect. The Eurodollar Rate shall be
adjusted with respect to Eurodollar Rate Loans without notice or demand of any kind on the
effective date of any change in the Reserve Percentage as of such effective date. Upon and after
the occurrence of an Event of Default, and during the continuation thereof, (i) at the option of
Agent or at the direction of Required Lenders, the Obligations shall bear interest at the
applicable Revolving Interest Rate plus two(2%) percent per annum (as applicable, the “Default
Rate”).

     3.2. Letter of Credit and Acceptance Fees.

          (a) Borrower shall pay (x) to Agent, for the ratable benefit of Lenders, fees for each Letter
of Credit for the period from and excluding the date of issuance of same to and including the date
of expiration or termination, equal to the average daily face amount of each outstanding Letter of
Credit multiplied by the Applicable Eurodollar Rate Margin per annum, such fees to be calculated on
the basis of a 360-day year for the actual number of days elapsed
and to be payable quarterly in arrears on the first day of each quarter and on the last day of
the Term, and (y) to the Issuer, a fronting fee of one quarter of one percent (0.25%) per annum,
together with any and all administrative, issuance, amendment, payment and negotiation charges with
respect to Letters of Credit and all fees and expenses as agreed upon by the Issuer and the
Borrowing Agent in connection with any Letter of Credit, including in connection with the opening,
amendment or renewal of any such Letter of Credit and any acceptances created thereunder and shall
reimburse Agent for any and all fees and expenses, if any, paid by Agent to the Issuer (all of the
foregoing fees, the “Letter of Credit and Acceptance Fees”). All such charges shall be deemed
earned in full on the date when the same are due and payable hereunder and shall not be subject to
rebate or pro-ration upon the termination of this Agreement for any reason. Any such charge in
effect at the time of a particular transaction shall be the charge for that transaction,
notwithstanding any subsequent change in the Issuer’s prevailing charges for that type of
transaction. All Letter of Credit Fees and Acceptance Fees payable hereunder shall be deemed
earned in full on the date when the same are due and payable hereunder and shall not be subject to
rebate or pro-ration upon the termination of this Agreement for any reason.

     On demand, and subject to the terms and conditions of any agreements regarding Blocked
Accounts between Agent, Borrower, and Blocked Account Bank, Borrower will cause cash to be
deposited and maintained in an account with Agent, as cash collateral, in an amount equal to one
hundred and five percent (105%) of the Maximum Undrawn Amount of all outstanding Letters of Credit
and Acceptances, and Borrower hereby irrevocably authorizes Agent, in its Permitted Discretion, on
Borrower’s behalf and in Borrower’s name, to open such an account and to make and maintain deposits
therein, or in an account opened by Borrower, in the amounts required to

38

 

be made by Borrower, out
of the proceeds of Receivables or other Collateral or out of any other funds of Borrower coming
into any Lender’s possession at any time. Agent will invest such cash collateral (less applicable
reserves) in such short-term money-market items as to which Agent and Borrower mutually agree and
the net return on such investments shall be credited to such account and constitute additional cash
collateral. Borrower may not withdraw amounts credited to any such account except upon the
occurrence of all of the following: (w) the Event of Default is waived by Lenders, (x) payment and
performance in full of all Obligations, (y) the expiration of all Letters of Credit and (z) the
termination of this Agreement.

     3.3. Facility Fee. If, for any month during the Term, the average daily unpaid
balance of the Advances for each day of such month does not equal the Maximum Loan Amount, then
Borrower shall pay to Agent for the ratable benefit of Lenders a fee at a rate equal to one-fourth
of one percent (.25%) per annum on the amount by which the Maximum Loan Amount exceeds such average
daily unpaid balance. Such fee shall be payable to Agent in arrears on the first day of each month
with respect to the previous month.

     3.4. Fee Letter. Borrower shall pay the amounts required to be paid in the Fee Letter
in the manner and at the times required by the Fee Letter.

     3.5. Computation of Interest and Fees.
Interest and fees hereunder shall be computed on the basis of a year of 360 days and for the
actual number of days elapsed. If any payment to be made hereunder becomes due and payable on a
day other than a Business Day, the due date thereof shall be extended to the next succeeding
Business Day and interest thereon shall be payable at the applicable Revolving Interest Rate during
such extension.

     3.6. Maximum Charges. In no event whatsoever shall interest and other charges charged
hereunder exceed the highest rate permissible under law. In the event interest and other charges as
computed hereunder would otherwise exceed the highest rate permitted under law, such excess amount
shall be first applied to any unpaid principal balance owed by Borrower, and if the then remaining
excess amount is greater than the previously unpaid principal balance, Lenders shall promptly
refund such excess amount to Borrower and the provisions hereof shall be deemed amended to provide
for such permissible rate.

     3.7. Increased Costs. In the event that after the Closing Date, any Applicable Law,
treaty or governmental regulation, or any change therein or in the interpretation or application
thereof, or compliance by any Lender (for purposes of this Section 3.7, the term “Lender” shall
include Agent or any Lender and any corporation or bank controlling Agent or any Lender) and the
office or branch where Agent or any Lender (as so defined) makes or maintains any Eurodollar Rate
Loans, and any such request or directive (whether or not having the force of law) from any central
bank or other financial, monetary or other authority, shall:

          (a) subject Agent or any Lender to any tax of any kind whatsoever with respect to this
Agreement or any Other Document or change the basis of taxation of payments to Agent or any Lender
of principal, fees, interest or any other amount payable hereunder or under any Other Documents
(except for changes in the rate of tax on the overall net income of Agent or any Lender by the
jurisdiction in which it maintains its principal office);

39

 

          (b) impose, modify or hold applicable any reserve, special deposit, assessment or similar
requirement against assets held by, or deposits in or for the account of, advances or loans by, or
other credit extended by, any office of Agent or any Lender, including pursuant to Regulation D of
the Board of Governors of the Federal Reserve System; or

          (c) impose on Agent or any Lender or the London interbank Eurodollar market any other
condition with respect to this Agreement or any Other Document;

and the result of any of the foregoing is to increase the cost to Agent or any Lender of making,
renewing or maintaining its Advances hereunder by an amount that Agent or such Lender deems to be
material or to reduce the amount of any payment (whether of principal, interest or otherwise) in
respect of any of the Advances by an amount that Agent or such Lender deems to be material, then,
in any case Borrower shall promptly pay Agent or such Lender, upon its demand, such additional
amount as will compensate Agent or such Lender for such additional cost or such reduction, as the
case may be, provided that the foregoing shall not apply to increased costs which are reflected in
the Eurodollar Rate, as the case may be. Agent or such
Lender shall certify the amount of such additional cost or reduced amount to Borrowing Agent, and
such certification shall be conclusive absent manifest error.

     3.8. Basis For Determining Interest Rate Inadequate or Unfair. In the event that
after the Closing Date Agent or any Lender shall have determined that:

          (a) reasonable means do not exist for ascertaining the Eurodollar Rate applicable pursuant to
Section 2.2 hereof for any Interest Period; or

          (b) Dollar deposits in the relevant amount and for the relevant maturity are not available in
the London interbank Eurodollar market, with respect to an outstanding Eurodollar Rate Loan, a
proposed Eurodollar Rate Loan, or a proposed conversion of a Domestic Rate Loan into a Eurodollar
Rate Loan,

then Agent shall give Borrower prompt written, telephonic or telegraphic notice of such
determination. If such notice is given, (i) any such requested Eurodollar Rate Loan shall be made
as a Domestic Rate Loan, unless Borrower shall notify Agent no later than 10:00 a.m. (New York City
time) two (2) Business Days prior to the date of such proposed borrowing, that its request for such
borrowing shall be cancelled or made as an unaffected type of Eurodollar Rate Loan, (ii) any
Domestic Rate Loan or Eurodollar Rate Loan which was to have been converted to an affected type of
Eurodollar Rate Loan shall be continued as or converted into a Domestic Rate Loan, or, if Borrower
shall notify Agent, no later than 10:00 a.m. (New York City time) two (2) Business Days prior to
the proposed conversion, shall be maintained as an unaffected type of Eurodollar Rate Loan, and
(iii) any outstanding affected Eurodollar Rate Loans shall be converted into a Domestic Rate Loan,
or, if Borrower shall notify Agent, no later than 10:00 a.m. (New York City time) two (2) Business
Days prior to the last Business Day of the then current Interest Period applicable to such affected
Eurodollar Rate Loan, shall be converted into an unaffected type of Eurodollar Rate Loan, on the
last Business Day of the then current Interest Period for such affected Eurodollar Rate Loans.
Until such notice has been withdrawn, Lenders shall have no obligation to make an affected type of
Eurodollar Rate Loan or maintain outstanding affected Eurodollar Rate Loans and Borrower shall not
have the right to

40

 

convert a Domestic Rate Loan or an unaffected type of Eurodollar Rate Loan into
an affected type of Eurodollar Rate Loan.

     3.9. Capital Adequacy.

          (a) In the event that after the Closing Date Agent or any Lender shall have determined that
any Applicable Law, rule, regulation or guideline regarding capital adequacy, or any change
therein, or any change in the interpretation or administration thereof by any Governmental Body,
central bank or comparable agency charged with the interpretation or administration thereof, or
compliance by Agent or any Lender (for purposes of this Section 3.9, the term “Lender” shall
include Agent or any Lender and any corporation or bank controlling Agent or any Lender) and the
office or branch where Agent or any Lender (as so defined) makes or maintains any Eurodollar Rate
Loans with any request or directive regarding capital adequacy (whether or not having the force of
law) of any such authority, central bank or comparable agency, has or would have the effect of
reducing the rate of return on Agent or any Lender’s
capital as a consequence of its obligations hereunder to a level below that which Agent or
such Lender could have achieved but for such adoption, change or compliance (taking into
consideration Agent’s and each Lender’s policies with respect to capital adequacy) by an amount
deemed by Agent or any Lender to be material, then, from time to time, Borrower shall pay upon
demand to Agent or such Lender such additional amount or amounts as will compensate Agent or such
Lender for such reduction. In determining such amount or amounts, Agent or such Lender may use any
reasonable averaging or attribution methods. The protection of this Section 3.9 shall be available
to Agent and each Lender regardless of any possible contention of invalidity or inapplicability
with respect to the Applicable Law, regulation or condition.

          (b) A certificate of Agent or such Lender setting forth such amount or amounts as shall be
necessary to compensate Agent or such Lender with respect to Section 3.9(a) hereof when delivered
to Borrower shall be conclusive absent manifest error.

     3.10. Gross Up for Taxes. If Borrower shall be required by Applicable Law to withhold
or deduct any taxes from or in respect of any sum payable under this Agreement or any of the Other
Documents to Agent, or any Lender, assignee of any Lender, or Participant (each, individually, a
“Payee” and collectively, the “Payees”), (a) the sum payable to such Payee or Payees, as the case
may be, shall be increased as may be necessary so that, after making all required withholding or
deductions, the applicable Payee or Payees receives an amount equal to the sum it would have
received had no such withholding or deductions been made (the “Gross-Up Payment”), (b) Borrower
shall make such withholding or deductions, and (c) Borrower shall pay the full amount withheld or
deducted to the relevant taxation authority or other authority in accordance with Applicable Law.
Notwithstanding the foregoing, Borrower shall not be obligated to make any portion of the Gross-Up
Payment that is attributable to any withholding or deductions that would not have been paid or
claimed had the applicable Payee or Payees properly claimed a complete exemption with respect
thereto pursuant to Section 3.11 hereof.

     3.11. Withholding Tax Exemption.

          (a) Each Payee that is not incorporated under the Laws of the United States of America or a
state thereof (and, upon the written request of Agent, each other Payee) agrees that

41

 

it will
deliver to Borrower and Agent two (2) duly completed appropriate valid Withholding Certificates (as
defined under §1.1441-1(c)(16) of the Income Tax Regulations (“Regulations”)) certifying its status
(i.e., U.S. or foreign person) and, if appropriate, making a claim of reduced, or exemption from,
U.S. withholding tax on the basis of an income tax treaty or an exemption provided by the Code.
The term “Withholding Certificate” means a Form W-9; a Form W-8BEN; a Form W-8ECI; a Form W-8IMY
and the related statements and certifications as required under §1.1441-1(e)(2) and/or (3) of the
Regulations; a statement described in §1.871-14(c)(2)(v) of the Regulations; or any other
certificates under the Code or Regulations that certify or establish the status of a payee or
beneficial owner as a U.S. or foreign person.

          (b) Each Payee required to deliver to Borrower and Agent a valid Withholding Certificate
pursuant to Section 3.11(a) hereof shall deliver such valid Withholding Certificate as follows:
(A) each Payee which is a party hereto on the Closing Date shall deliver
such valid Withholding Certificate at least five (5) Business Days prior to the first date on
which any interest or fees are payable by Borrower hereunder for the account of such Payee; (B)
each Payee shall deliver such valid Withholding Certificate at least five (5) Business Days before
the effective date of such assignment or participation (unless Agent in its sole discretion shall
permit such Payee to deliver such Withholding Certificate less than five (5) Business Days before
such date in which case it shall be due on the date specified by Agent). Each Payee which so
delivers a valid Withholding Certificate further undertakes to deliver to Borrower and Agent two
(2) additional copies of such Withholding Certificate (or a successor form) on or before the date
that such Withholding Certificate expires or becomes obsolete or after the occurrence of any event
requiring a change in the most recent Withholding Certificate so delivered by it, and such
amendments thereto or extensions or renewals thereof as may be reasonably requested by Borrower or
Agent.

          (c) Notwithstanding the submission of a Withholding Certificate claiming a reduced rate of or
exemption from U.S. withholding tax required under Section 3.11(b) hereof, Agent shall be entitled
to withhold United States federal income taxes at the full 30% withholding rate if in its
reasonable judgment it is required to do so under the due diligence requirements imposed upon a
withholding agent under §1.1441-7(b) of the Regulations. Further, Agent is indemnified under
§1.1461-1(e) of the Regulations against any claims and demands of any Payee for the amount of any
tax it deducts and withholds in accordance with regulations under §1441 of the Code.

ratable benefit of Lenders immediately upon demand.

     Notwithstanding the foregoing, Lender acknowledges that Lender’s security interest in the

assign, transfer, create or suffer to exist a Lien upon or encumber or allow or suffer to be

44

 

encumbered in any way except for Permitted Encumbrances, any part of the Collateral. Borrower

time following demand by Agent for payment of all Obligations, Agent shall have the right to take
possession of the indicia of the Collateral and the
Collateral in whatever physical form contained, including: labels, stationery, documents,
instruments and advertising materials. If Agent exercises this right to take possession of the
Collateral, Borrower shall, upon demand, assemble it in the best manner possible and make it
available to Agent at a place reasonably convenient to Agent. In addition, with respect to all
Collateral, Agent and Lenders shall be entitled to all of the rights and remedies set forth herein
and further provided by the Uniform Commercial Code or other Applicable Law. Borrower shall, and,

checks, Inventory, documents or instruments in which Agent holds a security interest to deliver
same to Agent and/or subject to Agent’s order and if they shall come into Borrower’s possession,

be set aside from such earnings in connection with its business. All determinations pursuant to
this subsection shall be made in accordance with, or as required by, GAAP consistently applied in
the opinion of such independent public accountant as shall then be regularly engaged by Borrower.

     4.8. Financial Disclosure. Borrower hereby irrevocably authorizes and directs all
accountants and auditors employed by Borrower at any time during the Term to exhibit and deliver to
Agent copies of any of Borrower’s financial statements, trial balances or other accounting records
of any sort in the accountant’s or auditor’s possession, and to disclose to Agent any information
such accountants may have concerning Borrower’s financial status and business operations. Borrower
hereby authorizes all Governmental Bodies to furnish to Agent and each Lender copies of reports or
examinations relating to Borrower, whether made by Borrower or otherwise; however, Agent and each
Lender will attempt to obtain such information or materials directly from Borrower prior to
obtaining such information or materials from such accountants or Governmental Bodies.

     4.9. Compliance with Laws. Borrower shall comply in all material respects with all
Applicable Laws with respect to the Collateral or any part thereof or to the operation of
Borrower’s business the non-compliance with which may reasonably be expected to have a Material
Adverse Effect. Borrower may, however, contest or dispute any Applicable Laws in any reasonable
manner, provided that any
related Lien is inchoate or stayed and sufficient reserves are established to the reasonable
satisfaction of Agent to protect Agent’s Lien on or security interest in the Collateral.

45

 

     4.10. Inspection of Premises. If no Default or Event of Default exists, upon at least
one (1) Business Day’s prior notice, Agent and its agents may enter upon any of Borrower’s premises
at any time during business hours and at any other reasonable time, and from time to time, for the
purpose of inspecting the Collateral and any and all records pertaining thereto and the operation
of Borrower’s business. If an Event of Default exists and is continuing, Agent, or its agent, may
enter upon any of Borrower’s premises at any time, in Agent’s sole discretion. Agent shall have
full access to and the right to audit, check, inspect and make abstracts and copies from Borrower’s
books, records, audits, correspondence and all other papers relating to the Collateral and the
operation of Borrower’s business. Notwithstanding anything contained in this paragraph, Agent may
not unreasonably interfere with Borrowers’ business operations for the purpose of said inspections,
unless an Event of Default exists and is continuing.

     4.11. Insurance. The assets and properties of Borrower at all times shall be
maintained in accordance with the requirements of all insurance carriers which provide insurance
with respect to the assets and properties of Borrower so that such insurance shall remain in full
force and effect. Borrower shall bear the full risk of any loss of any nature whatsoever with
respect to the Collateral. At Borrower’s own cost and expense in amounts and with carriers
acceptable to Agent, Borrower shall (a) keep all its insurable properties and properties in which
Borrower has an interest insured against the hazards of fire, flood, sprinkler leakage, those
hazards covered by extended coverage insurance and such other hazards, and for such amounts, as is
customary in the case of companies engaged in businesses similar to Borrower’s including business
interruption insurance; (b) maintain a bond or similar insurance coverage in such amounts as is
customary in the case of companies engaged in businesses similar to Borrower insuring against
larceny, embezzlement or other criminal misappropriation of insured’s officers and employees who
may either singly or jointly with others at any time have access to the assets or funds of Borrower
either directly or through authority to draw upon such funds or to direct generally the disposition
of such assets; (c) maintain public and product liability insurance against claims for personal
injury, death or property damage suffered by others; (d) maintain all such worker’s compensation or
similar insurance as may be required under the laws of any state or jurisdiction in which Borrower
is engaged in business; (e) furnish Agent with (i) evidence of all policies and the maintenance of
such policies by the renewal thereof on or before any expiration date, and copies of all renewed
policies as soon as is practicable after the renewal date (except that in the event any such
renewal policies are not renewed, an Event of Default shall have occurred), and (ii) appropriate
loss payable endorsements in form and substance satisfactory to Agent, naming Agent as a co-insured
and loss payee as its interests may appear with respect to all insurance coverage referred to in
clauses (a) and (c) above, and providing (A) that all proceeds thereunder shall be payable to
Agent, (B) no such insurance shall be affected by any act or neglect of the insured or owner of the
property described in such policy, and (C) that such policy and loss payable clauses may not be
cancelled, amended or terminated unless at least thirty (30) days’ prior written notice is given to
Agent. Notwithstanding anything contained herein, Borrower
hereby covenants to use its best efforts to provide Agent with copies of all policies and
evidence of the maintenance of such policies by the renewal thereof on or before two weeks prior to
said policies’ expiration. In the event of any loss thereunder, the carriers named therein hereby
are directed by Agent and Borrower to make payment for such loss to Agent and not to Borrower and
Agent jointly. If any insurance losses are paid by check, draft or other instrument payable to
Borrower and Agent jointly, Agent may endorse Borrower’s name thereon and do such other things as
Agent may deem advisable to reduce the same to cash. Agent is hereby authorized to

46

 

adjust and
compromise claims under insurance coverage referred to in clauses (a), and (b) above. All loss
recoveries received by Agent upon any such insurance may be applied to the Obligations, in such
order as Agent in its Permitted Discretion shall determine. Any surplus shall be paid by Agent to
Borrower or applied as may be otherwise required by law. Any deficiency thereon shall be paid by
Borrower to Agent, on demand.

     4.12. Failure to Pay Insurance. If Borrower fails to obtain insurance as hereinabove
provided, or to keep the same in force, Agent, if Agent so elects, may obtain such insurance and
pay the premium therefor on behalf of Borrower, and charge Borrower’s Account therefor as a
Revolving Advance and such expenses so paid shall be part of the Obligations.

     4.13. Payment of Taxes. Borrower will pay, when due, all taxes, assessments and other
Charges lawfully levied or assessed upon Borrower or any of the Collateral including real and
personal property taxes, assessments and charges and all franchise, income, employment, social
security benefits, withholding, and sales taxes. If any tax by any Governmental Body is or may be
imposed on or as a result of any transaction between Borrower and Agent or any Lender which Agent
or any Lender may be required to withhold or pay or if any taxes, assessments, or other Charges
remain unpaid after the date fixed for their payment, or if any claim shall be made which, in
Agent’s or any Lender’s opinion, may possibly create a valid Lien on the Collateral, Agent may
without notice to Borrower pay the taxes, assessments or other Charges and Borrower hereby
indemnifies and holds Agent and each Lender harmless in respect thereof. Agent will not pay any
taxes, assessments or Charges to the extent that Borrower is Properly Contesting those taxes,
assessments or Charges. The amount of any payment by Agent under this Section 4.13 shall be
charged to Borrower’s Account as a Revolving Advance and added to the Obligations and, until
Borrower shall furnish Agent with an indemnity therefor (or supply Agent with evidence satisfactory
to Agent that due provision for the payment thereof has been made), Agent may hold without interest
any balance standing to Borrower’s credit and Agent shall retain its security interest in and Lien
on any and all Collateral held by Agent.

     4.14. Payment of Leasehold Obligations. Borrower shall at all times pay, when and as
due, its rental obligations under all leases under which it is a tenant, and shall otherwise
comply, in all material respects, with all other terms of such leases and keep them in full force
and effect and, at Agent’s request will provide evidence of having done so.

     4.15. Receivables.

          (a) Nature of Receivables. Each of the Receivables shall be a bona fide and valid
account representing a bona fide indebtedness incurred by the Customer therein named, for a fixed
sum as set forth in the invoice relating thereto (provided immaterial or unintentional invoice
errors shall not be deemed to be a breach hereof) with respect to an absolute sale or lease and
delivery of goods upon stated terms of Borrower, or work, labor or services theretofore rendered by
Borrower as of the date each Receivable is created. Same shall be due and owing in accordance with
Borrower’s customary terms of sale without dispute, setoff or counterclaim except as may be stated
on the accounts receivable schedules delivered by Borrower to Agent.

          (b) Solvency of Customers. Each Customer, to the best of Borrower’s knowledge, as of
the date each Receivable is created, is and will be solvent and able to pay all

47

 

Receivables on
which the Customer is obligated in full when due or with respect to such Customers of Borrower who
are not solvent Borrower has set up on its books and in its financial records bad debt reserves
adequate to cover such Receivables.

          (c) Location of Borrower. Borrower’s chief executive office is located at Stafford,
Texas, and the Borrower’s respective operating offices are set out on Schedule 4.15(c). Until
written notice is given to Agent by Borrowing Agent of any other office at which Borrower keeps its
records pertaining to Receivables, all such records shall be kept at such executive and operating
offices.

          (d) Collection of Receivables. Until Borrower’s authority to do so is terminated by
Agent (which notice Agent may give at any time an Event of Default exists or when Agent in its sole
discretion deems it to be in Lenders’ best interest to do so), Borrower will, at Borrower’s sole
cost and expense, but on Agent’s behalf and for Agent’s account, collect as Agent’s property and in
trust for Agent all amounts received on Receivables, and shall not commingle such collections with
Borrower’s funds or use the same except to pay Obligations. Borrower shall deposit in the Blocked
Account or, upon request by Agent, deliver to Agent, in original form and on the date of receipt
thereof, all checks, drafts, notes, money orders, acceptances, cash and other evidences of
Indebtedness.

          (e) Notification of Assignment of Receivables. At any time an Event of Default
exists, Agent shall have the right to send notice of the assignment of, and Agent’s security
interest in and Lien on, the Receivables to any and all Customers or any third party holding or
otherwise concerned with any of the Collateral. Thereafter, Agent shall have the sole right to
collect the Receivables, take possession of the Collateral, or both. Agent’s actual collection
expenses, including, but not limited to, stationery and postage, telephone and telegraph,
secretarial and clerical expenses and the salaries of any collection personnel used for collection,
may be charged to Borrower’s Account and added to the Obligations.

          (f) Power of Agent to Act on Borrower’s Behalf. Agent shall have the right to
receive, endorse, assign and/or deliver in the name of Agent or Borrower any and all checks,
drafts and other instruments for the payment of money relating to the Receivables, and Borrower
hereby waives notice of presentment, protest and non-payment of any instrument so endorsed.
Borrower hereby constitutes Agent or Agent’s designee as Borrower’s attorney with power (i) to
endorse Borrower’s name upon any notes, acceptances, checks, drafts, money orders or other
evidences of payment or Collateral; (ii) to sign Borrower’s name on any invoice or bill of lading
relating to any of the Receivables, drafts against Customers, assignments and verifications of
Receivables; (iii) to send verifications of Receivables to any Customer; (iv) to sign Borrower’s
name on all financing statements or any other documents or instruments deemed necessary or
appropriate by Agent to preserve, protect, or perfect Agent’s interest in the Collateral and to
file same; (v) to demand payment of the Receivables; (vi) to enforce payment of the Receivables by
legal proceedings or otherwise; (vii) to exercise all of Borrower’s rights and remedies with
respect to the collection of the Receivables and any other Collateral; (viii) to settle, adjust,
compromise, extend or renew the Receivables; (ix) to settle, adjust or compromise any legal
proceedings brought to collect Receivables; (x) to prepare, file and sign Borrower’s name on a
proof of claim in bankruptcy or similar document against any Customer; (xi) to prepare, file and
sign Borrower’s name on any notice of Lien, assignment or satisfaction of Lien or similar

48

 

document
in connection with the Receivables; and (xii) to do all other acts and things necessary to carry
out this Agreement. All acts of said attorney or designee are hereby ratified and approved, and
said attorney or designee shall not be liable for any acts of omission or commission nor for any
error of judgment or mistake of fact or of law, unless done maliciously or with gross (not mere)
negligence (as determined by a court of competent jurisdiction in a final non-appealable judgment);
this power being coupled with an interest is irrevocable while any of the Obligations remain
unpaid. Agent shall have the right at any time following the occurrence of an Event of Default or
Default, to change the address for delivery of mail addressed to Borrower to such address as Agent
may designate and to receive, open and dispose of all mail addressed to Borrower.

          (g) No Liability. Neither Agent nor any Lender shall, under any circumstances or in
any event whatsoever (other than for its gross negligence or willful misconduct), have any
liability for any error or omission or delay of any kind occurring in the settlement, collection or
payment of any of the Receivables or any instrument received in payment thereof, or for any damage
resulting therefrom. Following the occurrence of an Event of Default or Default Agent may, without
notice or consent from Borrower, sue upon or otherwise collect, extend the time of payment of,
compromise or settle for cash, credit or upon any terms any of the Receivables or any other
securities, instruments or insurance applicable thereto and/or release any obligor thereof. Agent
is authorized and empowered to accept following the occurrence of an Event of Default or Default
the return of the goods represented by any of the Receivables, without notice to or consent by
Borrower, all without discharging or in any way affecting Borrower’s liability hereunder.

          (h) Establishment of a Lockbox Account, Dominion Account. All proceeds of Collateral
shall be subject to the following springing cash dominion accounts: (i) lockbox account, dominion
account or such other “blocked account” (“Blocked Accounts”) established at a bank or banks (each
such bank, a “Blocked Account Bank”) pursuant to an arrangement with such Blocked Account Bank as
may be selected by Borrower and be reasonably acceptable to Agent; and (ii) depository accounts
(“Depository Accounts”) established at the Agent for the deposit of such proceeds. Borrower, Agent
and each Blocked Account Bank shall enter into a deposit account control agreement in form and
substance satisfactory to Agent directing such Blocked Account Bank, upon the triggering of the
event specified in the Blocked Account Agreement, to transfer such funds so deposited to Agent,
either to any account maintained by
Agent at said Blocked Account Bank or by wire transfer to appropriate account(s) of Agent.
All funds deposited in such Blocked Accounts shall immediately become the property of Agent and
Borrower shall obtain the agreement by such Blocked Account Bank to waive any offset rights against
the funds so deposited. Neither Agent nor any Lender assumes any responsibility for such blocked
account arrangement, including any claim of accord and satisfaction or release with respect to
deposits accepted by any Blocked Account Bank thereunder. All deposit accounts and investment
accounts of Borrower and its Subsidiaries are set forth on Schedule 4.15(h).

     Notwithstanding the foregoing, Borrower shall use its best efforts to establish any number of,
as Agent may deem appropriate in its Permitted Discretion, new lockbox accounts with Agent within
forty-five (45) days of the Closing Date. The funds deposited in said lockbox accounts shall flow
into one (1) funding account established with Agent. Until such time as said new lockbox and
funding account are established, Borrower’s funds shall be captured in the

49

 

lockbox accounts
pursuant to Section 6.12 and shall be subject to a blocked account agreement by and among Agent,
Borrowing Agent, and Blocked Account Bank, in a form acceptable to Agent in its Permitted
Discretion.

          (i) Adjustments. Borrower will not, without Agent’s consent, compromise or adjust any
Receivables (or extend the time for payment thereof) or accept any returns of merchandise or grant
any additional discounts, allowances or credits thereon except for those compromises, adjustments,
returns, discounts, credits and allowances as have been heretofore customary in the business of
Borrower.

     4.16. Inventory. To the extent Inventory held for sale or lease has been produced by

Standards Act of 1938, as amended, and all rules, regulations and orders thereunder.

statute, ordinance, code, rule or regulation. Borrower shall have the right to sell Equipment to
the extent set forth in Section 4.3 hereof.

     4.18. Exculpation of Liability. Nothing herein contained shall be construed to
constitute Agent or any Lender as Borrower’s agent for any purpose whatsoever, nor shall Agent or
any Lender be responsible or liable for any shortage, discrepancy, damage, loss or destruction of
any part of the Collateral wherever the same may be located unless resulting from their gross
negligence or willful misconduct. Neither Agent nor any Lender, whether by anything herein or in
any assignment or otherwise, assume any of Borrower’s obligations under any contract or agreement
assigned to Agent or such Lender, and neither Agent nor any Lender shall be responsible in any way
for the performance by Borrower of any of the terms and conditions thereof.

     4.19. Environmental Matters.

          (a) Borrower shall ensure that the Real Property as set forth on Schedule 4.19 hereof and all
operations and businesses conducted thereon remains in compliance with all Environmental Laws and
they shall not place or permit to be placed any Hazardous Substances on any Real Property except as
permitted by Applicable Law or appropriate Governmental Bodies.

          (b) Borrower shall establish and maintain a system to assure and monitor continued compliance
with all applicable Environmental Laws which system shall include periodic reviews of such
compliance.

          (c) Borrower shall (i) employ in connection with the use of the Real Property appropriate
technology necessary to maintain compliance with any applicable Environmental Laws and (ii) dispose
of any and all Hazardous Waste generated at the Real Property only at facilities and with carriers
that maintain valid permits under RCRA and any other applicable Environmental Laws. Borrower shall
use its best efforts to obtain certificates of disposal, such

50

 

as hazardous waste manifest receipts,
from all treatment, transport, storage or disposal facilities or operators employed by Borrower in
connection with the transport or disposal of any Hazardous Waste generated at the Real Property.

          (d) In the event Borrower obtains, gives or receives notice of any Release or threat of
Release of a reportable quantity of any Hazardous Substances at the Real Property (any such event
being hereinafter referred to as a “Hazardous Discharge”) or receives any notice of violation,
request for information or notification that it is potentially responsible for investigation or
cleanup of environmental conditions at the Real Property, demand letter or complaint, order,
citation, or other written notice with regard to any Hazardous Discharge or violation of
Environmental Laws affecting the Real Property or Borrower’s interest therein (any of the foregoing
is referred to herein as an “Environmental Complaint”) from any Person, including any state agency
responsible in whole or in part for environmental matters in the state in which the Real Property
is located or the United States Environmental Protection Agency (any such person or entity
hereinafter the “Authority”), then Borrowing Agent shall, within ten (10) Business Days, give
written notice of same to Agent detailing facts and circumstances of which Borrower is aware giving
rise to the Hazardous Discharge or Environmental Complaint. Such information is to be provided to
allow Agent to protect its security interest in and Lien on the Real Property and the Collateral
and is not intended to create nor shall it create any obligation upon Agent or any Lender with
respect thereto.

          (e) Borrower shall promptly forward to Agent copies of any request for information,
notification of potential liability, demand letter relating to potential responsibility with
respect to the investigation or cleanup of Hazardous Substances at any other site owned, operated
or used by Borrower to dispose of Hazardous Substances and shall continue to forward copies of
correspondence between Borrower and the Authority regarding such claims to Agent until the claim is
settled. Borrower shall promptly forward to Agent copies of all documents and reports concerning a
Hazardous Discharge at the Real Property that Borrower is required to file under any Environmental
Laws. Such information is to be provided solely to allow Agent to protect Agent’s security
interest in and Lien on the Real Property and the Collateral.

          (f) Borrower shall respond promptly to any Hazardous Discharge or Environmental Complaint and
take all necessary action in order to safeguard the health of any Person and to avoid subjecting
the Collateral or Real Property to any Lien. If Borrower shall fail to respond promptly to any
Hazardous Discharge or Environmental Complaint or Borrower shall fail to comply with any of the
requirements of any Environmental Laws, Agent on behalf of Lenders may, but without the obligation
to do so, for the sole purpose of protecting Agent’s interest in the Collateral: (A) give such
notices or (B) enter onto the Real Property (or authorize third parties to enter onto the Real
Property) and take such actions as Agent (or such third parties as directed by Agent) deem
reasonably necessary or advisable, to clean up, remove, mitigate or otherwise deal with any such
Hazardous Discharge or Environmental Complaint. All reasonable costs and expenses incurred by
Agent and Lenders (or such third parties) in the exercise of any such rights, including any sums
paid in connection with any judicial or administrative investigation or proceedings, fines and
penalties, together with interest thereon from the date expended at the Default Rate shall be paid
upon demand by Borrower, and until paid shall be added to and become a part of the Obligations
secured by the Liens created by the terms of this Agreement or any other agreement between Agent,
any Lender and Borrower.

51

 

          (g) If a Hazardous Discharge occurs, promptly upon the written request of Agent, Borrower
shall provide Agent, at Borrower’s expense, with an environmental site assessment or environmental
audit report prepared by an environmental engineering firm acceptable in the reasonable opinion of
Agent, to assess with a reasonable degree of certainty the existence of a Hazardous Discharge and
the potential costs in connection with abatement, cleanup and removal of any Hazardous Substances
found on, under, at or within the Real Property. Any report or investigation of such Hazardous
Discharge proposed and acceptable to an appropriate Authority that is charged to oversee the
clean-up of such Hazardous Discharge shall be acceptable to Agent. If such estimates, individually
or in the aggregate, exceed $250,000, Agent shall have the right to require Borrower to post a
bond, letter of credit or other security reasonably satisfactory to Agent to secure payment of
these costs and expenses.

          (h) Borrower shall defend and indemnify Agent and Lenders and hold Agent, Lenders and their
respective employees, agents, directors and officers harmless from and against all loss, liability,
damage and expense, claims, costs, fines and penalties, including attorney’s fees, suffered or
incurred by Agent or Lenders under or on account of any Environmental Laws, including the assertion
of any Lien thereunder, with respect to any Hazardous Discharge, the presence of any Hazardous
Substances affecting the Real Property, whether or not the same originates or emerges from the Real
Property or any contiguous real estate, including any loss of value of the Real Property as a
result of the foregoing except to the extent such loss, liability, damage and expense is
attributable to any Hazardous Discharge resulting from actions on the part of Agent or any Lender.
Borrower’s obligations under this Section 4.19 shall arise upon the discovery of the presence of
any Hazardous Substances at the Real Property which is not being stored, handled, processed, or
transported in accordance with Applicable Law, whether or not any federal, state, or local
environmental agency has taken or threatened any action in connection with the presence of any
Hazardous Substances. Borrower’s obligation hereunder shall survive the termination of this
Agreement until the applicable statutes of limitations expire. Borrower’s indemnifications
hereunder shall survive the termination of this Agreement.

          (i) For purposes of Section 4.19 and 5.7, all references to Real Property shall
be deemed to include all of Borrower’s right, title and interest in and to its owned and
leased premises.

secured.

declarations of fact that are made under an authentic act before a Notary Public in the presence of
two witnesses, by a person declaring such facts to lie within his or her knowledge, shall

remedies provided for herein, under the Other Documents, under the Uniform Commercial Code and at
law or equity generally, including the right to foreclose the security interests granted herein and
to realize upon any Collateral by any available judicial procedure and/or to take possession of and
sell any or all of the Collateral with or without judicial process. Agent may enter any of
Borrower’s premises or other premises without legal process and without incurring liability to
Borrower therefor, and Agent may thereupon, or at any time thereafter, in its Permitted Discretion
without notice or demand, take the Collateral and remove the same to such place as Agent may deem
advisable and Agent may require Borrower to make the Collateral available to Agent at a convenient
place. With or without having the Collateral at the time or place of sale, Agent may sell the
Collateral, or any part thereof, at public or private sale, at any time or place, in one or more
sales, at such price or prices, and upon such terms, either for cash, credit or future delivery, as
Agent may elect. Except as to that part of the Collateral which is perishable or threatens to
decline speedily in value or is of a type customarily sold on a recognized market, Agent shall give
Borrower reasonable notification of such sale or sales, it being agreed that in all events written
notice mailed to Borrower at least ten (10) days prior to such sale or sales is reasonable
notification. At any public sale Agent or any Lender may bid for and become the purchaser, and
Agent, any Lender or any other purchaser at any such sale thereafter shall hold the Collateral sold
absolutely free from any claim or right of whatsoever kind, including any equity of redemption and
all such claims, rights and equities are hereby expressly waived and released by Borrower. In
connection with the exercise of the foregoing remedies, including the sale of Inventory, Agent is
granted a perpetual nonrevocable, royalty free, nonexclusive license and Agent is granted
permission to use all of Borrower’s (a) trademarks, trade styles, trade names, patents, patent
applications, copyrights, service marks, licenses, franchises and other proprietary rights which
are used or useful in connection with Inventory for the purpose of marketing, advertising for sale
and selling or otherwise disposing of such Inventory and (b) Equipment for the purpose of
completing the manufacture of unfinished goods. The cash proceeds realized from the sale of any
Collateral shall be applied to the Obligations in the order set forth in Section 11.5 hereof.
Noncash proceeds will only be applied to the Obligations as they are converted into cash. If any
deficiency shall arise, Borrower shall remain liable to Agent and Lenders therefor.

          (b) To the extent that Applicable Law imposes duties on the Agent to exercise remedies in a
commercially reasonable manner, Borrower acknowledges and agrees that it is not
commercially unreasonable for the Agent (i) to fail to incur expenses reasonably deemed
significant by the Agent to prepare Collateral for disposition or otherwise to complete raw
material or work in process into finished goods or other finished products for disposition, (ii) to
fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if
not required by other law, to fail to obtain governmental or third party consents for the
collection or disposition of Collateral to be collected or disposed of, (iii) to fail to exercise
collection remedies against Customers or other Persons obligated on Collateral or to remove Liens
on or any adverse claims against Collateral, (iv) to exercise collection remedies against Customers
and other Persons obligated on Collateral directly or through the use of collection agencies and
other collection specialists, (v) to advertise dispositions of Collateral through publications or
media of general circulation, whether or not the Collateral is of a specialized nature, (vi) to
contact other

79

 

Persons, whether or not in the same business as the Borrower, for expressions of
interest in acquiring all or any portion of such Collateral, (vii) to hire one or more professional
auctioneers to assist in the disposition of Collateral, whether or not the Collateral is of a
specialized nature, (viii) to dispose of Collateral by utilizing internet sites that provide for
the auction of assets of the types included in the Collateral or that have the reasonable capacity
of doing so, or that match buyers and sellers of assets, (ix) to dispose of assets in wholesale
rather than retail markets, (x) to disclaim disposition warranties, such as title, possession or
quiet enjoyment, (xi) to purchase insurance or credit enhancements to insure the Agent against
risks of loss, collection or disposition of Collateral or to provide to the Agent a guaranteed
return from the collection or disposition of Collateral, or (xii) to the extent deemed appropriate
by the Agent, to obtain the services of other brokers, investment bankers, consultants and other
professionals to assist the Agent in the collection or disposition of any of the Collateral.
Borrower acknowledges that the purpose of this Section 11.1(b) is to provide non-exhaustive
indications of what actions or omissions by the Agent would not be commercially unreasonable in the
Agent’s exercise of remedies against the Collateral and that other actions or omissions by the
Agent shall not be deemed commercially unreasonable solely on account of not being indicated in
this Section 11.1(b). Without limitation upon the foregoing, nothing contained in this Section
11.1(b) shall be construed to grant any rights to Borrower or to impose any duties on Agent that
would not have been granted or imposed by this Agreement or by Applicable Law in the absence of
this Section 11.1(b).

     11.2. Agent’s Discretion. Agent shall have the right in its sole discretion to
determine which rights, Liens, security interests or remedies Agent may at any time pursue,
relinquish, subordinate, or modify or to take any other action with respect thereto and such
determination will not in any way modify or affect any of Agent’s or Lenders’ rights hereunder.

     11.3. Setoff. Subject to Section 14.12, in addition to any other rights which Agent
or any Lender may have under Applicable Law, upon the occurrence of an Event of Default hereunder,
Agent and such Lender shall have a right, immediately and without notice of any kind, to apply
Borrower’s property held by Agent and such Lender to reduce the Obligations.

     11.4. Rights and Remedies not Exclusive.
The enumeration of the foregoing rights and remedies is not intended to be exhaustive and the
exercise of any rights or remedy shall not preclude the exercise of any other right or remedies
provided for herein or otherwise provided by law, all of which shall be cumulative and not
alternative.

     11.5. Allocation of Payments After Event of Default. Notwithstanding any other
provisions of this Agreement to the contrary, after the occurrence and during the continuance of an
Event of Default, all amounts collected or received by the Agent on account of the Obligations or
any other amounts outstanding under any of the Other Documents or in respect of the Collateral may,
at Agent’s Permitted Discretion, be paid over or delivered as follows:

     FIRST, to the payment of all reasonable out-of-pocket costs and expenses (including reasonable
attorneys’ fees) of the Agent in connection with enforcing its rights and the rights of the Lenders
under this Agreement and the Other Documents and any protective advances made by the Agent with
respect to the Collateral under or pursuant to the terms of this Document;

80

 

     SECOND, to payment of any fees owed to the Agent;

     THIRD, to the payment of all reasonable out-of-pocket costs and expenses (including reasonable
attorneys’ fees) of the Agent in connection with enforcing its rights under this Agreement and the
Other Documents or otherwise with respect to the Obligations owing to such Lender;

     FOURTH, to the payment of all of the Obligations consisting of accrued fees and interest;

     FIFTH, to the payment of the outstanding principal amount of the Obligations (including the
payment or cash collateralization of any outstanding Letters of Credit);

     SIXTH, to all other Obligations and other obligations which shall have become due and payable
under the Other Documents or otherwise and not repaid pursuant to clauses “FIRST” through “FIFTH”
above; and

     SEVENTH, to the payment of the surplus, if any, to whoever may be lawfully entitled to receive
such surplus.

     In carrying out the foregoing, (i) amounts received shall be applied in the numerical order
provided until exhausted prior to application to the next succeeding category; (ii) each of the
Lenders shall receive (so long as it is not a Defaulting Lender) an amount equal to its pro rata
share (based on the proportion that the then outstanding Advances held by such Lender bears to the
aggregate then outstanding Advances) of amounts available to be applied pursuant to clauses
“FOURTH”, “FIFTH” and “SIXTH” above; and (iii) to the extent that any amounts available for
distribution pursuant to clause “FIFTH” above are attributable to the issued but undrawn amount of
outstanding Letters of Credit, such amounts shall be held by the Agent in a cash collateral account
and applied (A) first, to reimburse the Issuer from time to time for any drawings under such
Letters of Credit and (B) then, following the expiration of all Letters of Credit, to all other
obligations of the types described in clauses “FIFTH” and “SIXTH” above in the manner provided
in this Section 11.5.

XII WAIVERS AND JUDICIAL PROCEEDINGS.

     12.1. Waiver of Notice. Borrower hereby waives notice of non-payment of any of the
Receivables, demand, presentment, protest and notice thereof with respect to any and all
instruments, notice of acceptance hereof, notice of loans or advances made, credit extended,
Collateral received or delivered, or any other action taken in reliance hereon, and all other
demands and notices of any description, except such as are expressly provided for herein.

     12.2. Delay. No delay or omission on Agent’s or any Lender’s part in exercising any
right, remedy or option shall operate as a waiver of such or any other right, remedy or option or
of any Default or Event of Default.

     12.3. Jury Waiver. EACH PARTY TO THIS AGREEMENT HEREBY EXPRESSLY WAIVES ANY RIGHT TO
TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (A) ARISING UNDER THIS AGREEMENT OR
ANY OTHER

81

 

INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR (B) IN
ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO OR ANY OF
THEM WITH RESPECT TO THIS AGREEMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR
DELIVERED IN CONNECTION HEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO IN EACH CASE
WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE
AND EACH PARTY HEREBY CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE
DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL
COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENTS OF THE
PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

XIII EFFECTIVE DATE AND TERMINATION.

     13.1. Term. This Agreement, which shall inure to the benefit of and shall be binding
upon the respective successors and permitted assigns of Borrower, Agent and each Lender, shall
become effective on the date hereof and shall continue in full force and effect until May 24, 2008
(the “Term”) unless sooner terminated as herein provided. Borrower may terminate this Agreement at
any time upon ninety (90) days’ prior written notice upon payment in full of the Obligations. In
the event the Obligations are prepaid in full prior to the last day of the Term (the date of such
prepayment hereinafter referred to as the “Early Termination Date”), Borrower shall pay to
Agent for the benefit of Lenders an early termination fee in an amount equal to (x) One percent of
the Maximum Loan Amount if the Early Termination Date occurs on or after the Closing Date to and
including the date immediately preceding the first anniversary of the Closing Date, (y) 0.75% of
the Maximum Loan Amount if the Early Termination Date occurs on or after the first anniversary of
the Closing Date to and including the date immediately preceding the second anniversary of the
Closing Date, and (z) $0.25% of the Maximum Loan Amount if the Early Termination Date occurs on or
after the second anniversary of the Closing Date to and including the date immediately preceding
the third anniversary of the Closing Date.

     13.2. Termination. The termination of the Agreement shall not affect Borrower’s,
Agent’s or any Lender’s rights, or any of the Obligations having their inception prior to the
effective date of such termination, and the provisions hereof shall continue to be fully operative
until all transactions entered into, rights or interests created or Obligations have been fully
paid, disposed of, concluded or liquidated. The security interests, Liens and rights granted to
Agent and Lenders hereunder and the financing statements filed hereunder shall continue in full
force and effect, notwithstanding the termination of this Agreement or the fact that Borrower’s
Account may from time to time be temporarily in a zero or credit position, until all of the
Obligations of Borrower have been indefeasibly paid and performed in full after the termination of
this Agreement or Borrower has furnished Agent and Lenders with an indemnification satisfactory to
Agent and Lenders with respect thereto. Accordingly, Borrower waives any rights which it may have
under the Uniform Commercial Code to demand the filing of termination statements with respect to
the Collateral, and Agent shall not be required to send such termination statements to Borrower, or
to file them with any filing office, unless and until this Agreement shall have been terminated in
accordance with its terms and all Obligations have been

82

 

indefeasibly paid in full in immediately
available funds. All representations, warranties, covenants, waivers and agreements contained
herein shall survive termination hereof until all Obligations are indefeasibly paid and performed
in full.

XIV REGARDING AGENT.

     14.1. Appointment. Each Lender hereby designates PNC to act as Agent for such Lender
under this Agreement and the Other Documents. Each Lender hereby irrevocably authorizes Agent to
take such action on its behalf under the provisions of this Agreement and the Other Documents and
to exercise such powers and to perform such duties hereunder and thereunder as are specifically
delegated to or required of Agent by the terms hereof and thereof and such other powers as are
reasonably incidental thereto and Agent shall hold all Collateral, payments of principal and
interest, fees (except the fees set forth in the Fee Letter), charges and collections (without
giving effect to any collection days) received pursuant to this Agreement, for the ratable benefit
of Lenders. Agent may perform any of its duties hereunder by or through its agents or employees.
As to any matters not expressly provided for by this Agreement (including collection of the
Revolving Credit Note) Agent shall not be required to exercise any discretion or take any action,
but shall be required to act or to refrain from acting (and shall be fully protected in so acting
or refraining from acting) upon the instructions of the Required Lenders, and such instructions
shall be binding; provided, however, that Agent shall not be required to take any action which
exposes Agent to liability or which is contrary to this Agreement or the Other Documents or
Applicable Law unless Agent is furnished with an indemnification reasonably satisfactory to Agent
with respect thereto.

     14.2. Nature of Duties. Agent shall have no duties or responsibilities except those
expressly set forth in this Agreement and the Other Documents. Neither Agent nor any of its
officers, directors, employees or agents shall be (i) liable for any action taken or omitted by
them as such hereunder or in connection herewith, unless caused by their gross (not mere)
negligence or willful misconduct (as determined by a court of competent jurisdiction in a final
non-appealable judgment), or (ii) responsible in any manner for any recitals, statements,
representations or warranties made by Borrower or any officer thereof contained in this Agreement,
or in any of the Other Documents or in any certificate, report, statement or other document
referred to or provided for in, or received by Agent under or in connection with, this Agreement or
any of the Other Documents or for the value, validity, effectiveness, genuineness, due execution,
enforceability or sufficiency of this Agreement, or any of the Other Documents or for any failure
of Borrower to perform its obligations hereunder. Agent shall not be under any obligation to any
Lender to ascertain or to inquire as to the observance or performance of any of the agreements
contained in, or conditions of, this Agreement or any of the Other Documents, or to inspect the
properties, books or records of Borrower. The duties of Agent as respects the Advances to Borrower
shall be mechanical and administrative in nature; Agent shall not have by reason of this Agreement
a fiduciary relationship in respect of any Lender; and nothing in this Agreement, expressed or
implied, is intended to or shall be so construed as to impose upon Agent any obligations in respect
of this Agreement except as expressly set forth herein.

     14.3. Lack of Reliance on Agent and Resignation. Independently and without reliance
upon Agent or any other Lender, each Lender has made and shall continue to make (i) its own
independent investigation of the financial condition and affairs of Borrower in connection with

83

 

the making and the continuance of the Advances hereunder and the taking or not taking of any action in
connection herewith, and (ii) its own appraisal of the creditworthiness of Borrower. Agent shall
have no duty or responsibility, either initially or on a continuing basis, to provide any Lender
with any credit or other information with respect thereto, whether coming into its possession
before making of the Advances or at any time or times thereafter except as shall be provided by
Borrower pursuant to the terms hereof. Agent shall not be responsible to any Lender for any
recitals, statements, information, representations or warranties herein or in any agreement,
document, certificate or a statement delivered in connection with or for the execution,
effectiveness, genuineness, validity, enforceability, collectibility or sufficiency of this
Agreement or any Other Document, or of the financial condition of Borrower, or be required to make
any inquiry concerning either the performance or observance of any of the terms, provisions or
conditions of this Agreement, the Revolving Credit Note, the Other Documents or the financial
condition of Borrower, or the existence of any Event of Default or any Default.

     Agent may resign on sixty (60) days’ written notice to each of Lenders and Borrowing Agent and
upon such resignation, the Required Lenders will promptly designate a successor Agent reasonably
satisfactory to Borrower.

     Any such successor Agent shall succeed to the rights, powers and duties of Agent, and the term
“Agent” shall mean such successor agent effective upon its appointment, and the former Agent’s
rights, powers and duties as Agent shall be terminated, without any other or further act or deed on
the part of such former Agent. After any Agent’s resignation as Agent, the provisions of this
Article XIV shall inure to its benefit as to any actions taken or omitted to be taken by it while
it was Agent under this Agreement.

     14.4. Certain Rights of Agent. If Agent shall request instructions from Lenders with
respect to any act or action (including failure to act) in connection with this Agreement or any
Other Document, Agent shall be entitled to refrain from such act or taking such action unless and
until Agent shall have received instructions from the Required Lenders; and Agent shall not incur
liability to any Person by reason of so refraining. Without limiting the foregoing, Lenders shall
not have any right of action whatsoever against Agent as a result of its acting or refraining from
acting hereunder in accordance with the instructions of the Required Lenders.

     14.5. Reliance. Agent shall be entitled to rely, and shall be fully protected in
relying, upon any note, writing, resolution, notice, statement, certificate, telex, teletype or
telecopier message, cablegram, order or other document or telephone message believed by it to be
genuine and correct and to have been signed, sent or made by the proper person or entity, and, with
respect to all legal matters pertaining to this Agreement and the Other Documents and its duties
hereunder, upon advice of counsel selected by it. Agent may employ agents and attorneys-in-fact
and shall not be liable for the default or misconduct of any such agents or attorneys-in-fact
selected by Agent with reasonable care.

     14.6. Notice of Default. Agent shall not be deemed to have knowledge or notice of the
occurrence of any Default or Event of Default hereunder or under the Other Documents, unless Agent
has received notice from a Lender or Borrower referring to this Agreement or the Other Documents,
describing such Default or Event of Default and stating that such notice is a “notice of default”.
In the event that Agent receives such a notice, Agent shall give notice thereof to

84

 

Lenders. Agent shall take such action with respect to such Default or Event of Default as shall be reasonably
directed by the Required Lenders; provided, that, unless and until Agent shall have received such
directions, Agent may (but shall not be obligated to) take such action, or refrain from taking such
action, with respect to such Default or Event of Default as it shall deem advisable in the best
interests of Lenders.

     14.7. Indemnification. To the extent Agent is not reimbursed and indemnified by
Borrower, each Lender will reimburse and indemnify Agent in proportion to its respective portion of the Advances (or, if
no Advances are outstanding, according to its Commitment Percentage), from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted
against Agent in performing its duties hereunder, or in any way relating to or arising out of this
Agreement or any Other Document; provided that, Lenders shall not be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements resulting from Agent’s gross (not mere) negligence or willful misconduct (as
determined by a court of competent jurisdiction in a final non-appealable judgment).

     14.8. Agent in its Individual Capacity. With respect to the obligation of Agent to
lend under this Agreement, the Advances made by it shall have the same rights and powers hereunder
as any other Lender and as if it were not performing the duties as Agent specified herein; and the
term “Lender” or any similar term shall, unless the context clearly otherwise indicates, include
Agent in its individual capacity as a Lender. Agent may engage in business with Borrower as if it
were not performing the duties specified herein, and may accept fees and other consideration from
Borrower for services in connection with this Agreement or otherwise without having to account for
the same to Lenders.

     14.9. Delivery of Documents. To the extent Agent receives financial statements
required under Sections 9.7, 9.8, 9.9, 9.12 and 9.13 or Borrowing Base Certificates from Borrower
pursuant to the terms of this Agreement which Borrower is not obligated to deliver to each Lender,
Agent will promptly furnish such documents and information to Lenders.

     14.10. Borrower’s Undertaking to Agent. Without prejudice to its obligations to
Lenders under the other provisions of this Agreement, Borrower hereby undertakes with Agent to pay
to Agent from time to time on demand all amounts from time to time due and payable by it for the
account of Agent or Lenders or any of them pursuant to this Agreement to the extent not already
paid. Any payment made pursuant to any such demand shall pro tanto satisfy the relevant Borrower’s
obligations to make payments for the account of Lenders or the relevant one or more of them
pursuant to this Agreement.

     14.11. No Reliance on Agent’s Customer Identification Program. 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 USA 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

85

 

to or in connection with Borrower, its Affiliates or its agents, this Agreement, the Other Documents or the
transactions hereunder or contemplated hereby: (1) any identity verification procedures, (2) any record-keeping, (3) comparisons with government
lists, (4) customer notices or (5) other procedures required under the CIP Regulations or such
other laws.

     14.12. Other Agreements. Each of the Lenders agrees that it shall not, without the
express consent of Agent, and that it shall, to the extent it is lawfully entitled to do so, upon
the request of Agent, set off against the Obligations, any amounts owing by such Lender to Borrower
or any deposit accounts of Borrower now or hereafter maintained with such Lender. Anything in this
Agreement to the contrary notwithstanding, each of the Lenders further agrees that it shall not,
unless specifically requested to do so by Agent, take any action to protect or enforce its rights
arising out of this Agreement or the Other Documents, it being the intent of Lenders that any such
action to protect or enforce rights under this Agreement and the Other Documents shall be taken in
concert and at the direction or with the consent of Agent or Required Lenders.

XV BORROWING AGENCY.

     15.1. Borrowing Agency Provisions. Each Borrower hereby irrevocably designates
Borrowing Agent to be its representative, attorney and agent and in such capacity to borrow,
request Letters of Credit, sign and endorse notes, and execute and deliver all instruments,
documents, writings, certificates (including compliance certificates), financial statements,
reports and further assurances now or hereafter required hereunder, on behalf of such Borrower or
Borrowers, and to take any and all such action (including in respect of compliance with covenants)
on behalf of any Borrower under this Agreement or the Other Documents. Each Borrower agrees that
each notice, election, representation, warranty, covenant, agreement and undertaking made on its
behalf by Borrowing Agent shall be deemed for all purposes to have been made by such Borrower and
shall be binding and enforceable against such Borrower to the same extent as if the same had been
made directly by such Borrower. Each Borrower hereby authorizes Agent to issue Letters of Credit
and pay over or credit all loan proceeds hereunder in accordance with the request or instructions
of Borrowing Agent. Borrowing Agent hereby accepts such appointment.

          (a) The handling of this credit facility as a co-borrowing facility with a borrowing agent in
the manner set forth in this Agreement is solely as an accommodation to Borrowers and at their
request. Neither Agent nor any Lender shall incur liability to Borrowers as a result thereof. To
induce Agent and Lenders to do so and in consideration thereof, each Borrower hereby indemnifies
Agent and each Lender and holds Agent and each Lender harmless from and against any and all
liabilities, expenses, losses, damages and claims of damage or injury asserted against Agent or any
Lender by any Person arising from or incurred by reason of the handling of the financing
arrangements of Borrowers as provided herein, reliance by Agent or any Lender on any request or
instruction from Borrowing Agent or any other action taken by Agent or any Lender with respect to
this Section 15.1 except due to willful misconduct or gross (not mere) negligence by the
indemnified party.

          (b) All Obligations shall be joint and several, and each Borrower shall make
payment upon the maturity of the Obligations by acceleration or otherwise, and such obligation

86

 

and liability on the part of each Borrower shall in no way be affected by (i) any extension,
renewal or forbearance granted by Agent or any Lender to any Borrower, (ii) any failure of Agent or
any Lender to give any Borrower notice of borrowing or any other notice, (iii) any failure of Agent
or any Lender to pursue or preserve its rights or remedies against any Borrower or any Collateral,
or (iv) the release by Agent or any Lender of any Collateral now or thereafter acquired from any
Borrower, and such agreement by each Borrower to pay upon any notice issued pursuant thereto is
unconditional and unaffected by prior recourse by Agent or any Lender to the other Borrowers or any
Collateral for such Borrower’s Obligations or the lack thereof. Each Borrower waives all
suretyship defenses.

     15.2. Waiver of Subrogation. Each Borrower expressly waives any and all rights of
subrogation, reimbursement, indemnity, exoneration, contribution or any other claim which such
Borrower may now or hereafter have against the other Borrowers or other Persons directly or
contingently liable for the Obligations hereunder, or against or with respect to the other
Borrowers’ property (including, without limitation, any property which is Collateral for the
Obligations), arising from the existence or performance of this Agreement, in each case unless and
until termination of the obligations of Lenders to make Advances under this Agreement and the
payment, performance and satisfaction in full of the Obligations.

XVI MISCELLANEOUS

     16.1. Governing Law. This Agreement shall be governed by and construed in accordance
with the laws of the State of Texas applied to contracts to be performed wholly within the State of
Texas, except with regard to the realization of the Lender’s interest in the Collateral, in which
case the laws of the state in which such Collateral is located. Any judicial proceeding brought by
or against Borrower with respect to any of the Obligations, this Agreement, the Other Documents or
any related agreement may be brought in any court of competent jurisdiction in the State of Texas,
United States of America, and, by execution and delivery of this Agreement, Borrower accepts for
itself and in connection with its properties, generally and unconditionally, the non-exclusive
jurisdiction of the aforesaid courts, and irrevocably agrees to be bound by any judgment rendered
thereby in connection with this Agreement. Borrower hereby waives personal service of any and all
process upon it and consents that all such service of process may be made by registered mail
(return receipt requested) directed to Borrower at its address set forth in Section 16.6 and
service so made shall be deemed completed five (5) days after the same shall have been so deposited
in the mails of the United States of America. Nothing herein shall affect the right to serve
process in any manner permitted by law or shall limit the right of Agent or any Lender to bring
proceedings against Borrower in the courts of any other jurisdiction. Borrower waives any
objection to jurisdiction and venue of any action instituted hereunder and shall not assert any
defense based on lack of jurisdiction or venue or based upon forum non conveniens. Borrower waives
the right to remove any judicial proceeding brought against Borrower in any state court to any
federal court. Any judicial proceeding by Borrower against Agent or any Lender involving, directly
or indirectly, any matter or claim in any way arising out of, related to or connected with
this Agreement or any related agreement, shall be brought only in a federal or state court
located in the County of Harris, Southern District, State of Texas.

     16.2. Entire Understanding.

87

 

          (a) This Agreement and the documents executed concurrently herewith contain the entire
understanding between Borrower, Agent and each Lender and supersedes all prior agreements and
understandings, if any, relating to the subject matter hereof. Any promises, representations,
warranties or guarantees not herein contained and hereinafter made shall have no force and effect
unless in writing, signed by Borrower’s, Agent’s and each Lender’s respective officers. Neither
this Agreement nor any portion or provisions hereof may be changed, modified, amended, waived,
supplemented, discharged, cancelled or terminated orally or by any course of dealing, or in any
manner other than by an agreement in writing, signed by the party to be charged. Borrower
acknowledges that it has been advised by counsel in connection with the execution of this Agreement
and Other Documents and is not relying upon oral representations or statements inconsistent with
the terms and provisions of this Agreement.

          (b) The Required Lenders, Agent with the consent in writing of the Required Lenders, and
Borrower may, subject to the provisions of this Section 16.2 (b), from time to time enter into
written supplemental agreements to this Agreement or the Other Documents executed by Borrower, for
the purpose of adding or deleting any provisions or otherwise changing, varying or waiving in any
manner the rights of Lenders, Agent or Borrower thereunder or the conditions, provisions or terms
thereof of waiving any Event of Default thereunder, but only to the extent specified in such
written agreements; provided, however, that no such supplemental agreement shall, without the
consent of all Lenders:

               (i) increase the Commitment Percentage, the maximum dollar commitment of any Lender or the
Maximum Loan Amount

               (ii) extend the maturity of any Revolving Credit Note or the due date for any amount payable
hereunder, or decrease the rate of interest or reduce any fee payable by Borrower to Lenders
pursuant to this Agreement.

               (iii) alter the definition of the term Required Lenders or alter, amend or modify this Section
16.2(b).

               (iv) release any Collateral during any calendar year (other than in accordance with the
provisions of this Agreement) having an aggregate value in excess of $125,000.00.

               (v) change the rights and duties of Agent.

               (vi) permit any Revolving Advance to be made if after giving effect thereto the total of
Revolving Advances outstanding hereunder would exceed the Formula Amount for more than sixty (60)
consecutive Business Days or exceed one hundred and five percent (105%) of the Formula Amount.

               (vii) increase the Advance Rates above the Advance Rates in effect on
the Closing Date.

     Any such supplemental agreement shall apply equally to each Lender and shall be binding upon
Borrower, Lenders and Agent and all future holders of the Obligations. In the case of any waiver,
Borrower, Agent and Lenders shall be restored to their former positions and

88

 

rights, and any Event of Default waived shall be deemed to be cured and not continuing, but no waiver of a specific Event
of Default shall extend to any subsequent Event of Default (whether or not the subsequent Event of
Default is the same as the Event of Default which was waived), or impair any right consequent
thereon.

     In the event that Agent requests the consent of a Lender pursuant to this Section 16.2 and
such Lender shall not respond or reply to Agent in writing within five (5) days of delivery of such
request, such Lender shall be deemed to have consented to the matter that was the subject of the
request. In the event that Agent requests the consent of a Lender pursuant to this Section 16.2
and such consent is denied, then PNC may, at its option, require such Lender to assign its interest
in the Advances to PNC or to another Lender or to any other Person designated by the Agent (the
“Designated Lender”), for a price equal to the then outstanding principal amount thereof plus
accrued and unpaid interest and fees due such Lender, which interest and fees shall be paid when
collected from Borrower. In the event PNC elects to require any Lender to assign its interest to
PNC or to the Designated Lender, PNC will so notify such Lender in writing within forty-five (45)
days following such Lender’s denial, and such Lender will assign its interest to PNC or the
Designated Lender no later than five (5) days following receipt of such notice pursuant to a
Commitment Transfer Supplement executed by such Lender, PNC or the Designated Lender, as
appropriate, and Agent.

     Notwithstanding (a) the existence of a Default or an Event of Default, (b) that any of the
other applicable conditions precedent set forth in Section 8.2 hereof have not been satisfied or
(c) any other provision of this Agreement, Agent may at its sole discretion and without the consent
of the Required Lenders, voluntarily permit the outstanding Revolving Advances at any time to
exceed the Formula Amount (the “Out-of-Formula Loans”). If Agent is willing in its sole and
absolute discretion to make such Out-of-Formula Loans, such Out-of-Formula Loans shall be payable
on demand and shall bear interest at the Default Rate; provided that, if Lenders do make
Out-of-Formula Loans, neither Agent nor Lenders shall be deemed thereby to have changed the limits
of Section 2.1(a). For purposes of this paragraph, the discretion granted to Agent hereunder shall
not preclude involuntary overadvances that may result from time to time due to the fact that the
Formula Amount was unintentionally exceeded for any reason, including, but not limited to,
Collateral previously deemed to be either “Eligible Receivables” or “Eligible Inventory”, as
applicable, becomes ineligible, collections of Receivables applied to reduce outstanding Revolving
Advances are thereafter returned for insufficient funds or overadvances are made to protect or
preserve the Collateral. In the event Agent involuntarily permits the outstanding Revolving
Advances to exceed the Formula Amount by more than ten percent (10%), Agent shall use its efforts
to have Borrower decrease such excess in as expeditious a manner as is practicable under the
circumstances and not inconsistent with the reason for such excess. Revolving Advances made after
Agent has determined the existence of involuntary overadvances shall be deemed to be involuntary
overadvances and shall be decreased in accordance with the preceding sentence.

     In addition to (and not in substitution of) the discretionary Revolving Advances permitted
above in this Section 16.2, the Agent is hereby authorized by Borrower and the Lenders, from time
to time in the Agent’s sole discretion, (A) after the occurrence and during the continuation of a
Default or an Event of Default, or (B) at any time that any of the other applicable conditions
precedent set forth in Section 8.2 hereof have not been satisfied, to make Revolving Advances to

89

 

Borrower on behalf of the Lenders which the Agent, in its reasonable business judgment, deems
necessary or desirable (a) to preserve or protect the Collateral, or any portion thereof, (b) to
enhance the likelihood of, or maximize the amount of, repayment of the Advances and other
Obligations, or (c) to pay any other amount chargeable to Borrower pursuant to the terms of this
Agreement; provided, that at any time after giving effect to any such Revolving Advances the
outstanding Revolving Advances do not exceed one hundred and ten percent (110%) of the Formula
Amount.

     16.3. Successors and Assigns; Participations; New Lenders.

          (a) This Agreement shall be binding upon and inure to the benefit of Borrower, Agent, each
Lender, all future holders of the Obligations and their respective successors and assigns, except
that Borrower may not assign or transfer any of its rights or obligations under this Agreement
without the prior written consent of Agent and each Lender.

          (b) Borrower acknowledges that in the regular course of commercial banking business one or
more Lenders may at any time and from time to time sell participating interests in the Advances to
other financial institutions (each such transferee or purchaser of a participating interest, a
“Participant”). Each Participant may exercise all rights of payment (including rights of set-off)
with respect to the portion of such Advances held by it or other Obligations payable hereunder as
fully as if such Participant were the direct holder thereof provided that Borrower shall not be
required to pay to any Participant more than the amount which it would have been required to pay to
Lender which granted an interest in its Advances or other Obligations payable hereunder to such
Participant had such Lender retained such interest in the Advances hereunder or other Obligations
payable hereunder and in no event shall Borrower be required to pay any such amount arising from
the same circumstances and with respect to the same Advances or other Obligations payable hereunder
to both such Lender and such Participant. Borrower hereby grants to any Participant a continuing
security interest in any deposits, moneys or other property actually or constructively held by such
Participant as security for the Participant’s interest in the Advances.

          (c) Any Lender may with the consent of Agent which shall not be unreasonably withheld or
delayed sell, assign or transfer all or any part of its rights under this Agreement and the Other
Documents to one or more additional banks or financial institutions and one or more additional
banks or financial institutions may commit to make Advances hereunder (each a “Purchasing Lender”,
and together with each Participant, each a “Transferee” and collectively the “Transferees”), in
minimum amounts of not less than $1,000,000.00, pursuant to a Commitment Transfer Supplement,
executed by a Purchasing Lender, the transferor Lender, and Agent and delivered to Agent for
recording. Upon such execution, delivery, acceptance and recording, from and after the transfer
effective date determined pursuant to such Commitment Transfer Supplement, (i) Purchasing Lender
thereunder shall be a party hereto and, to the extent provided in such Commitment Transfer
Supplement, have the rights and obligations of a Lender thereunder with a Commitment Percentage as set forth therein, and (ii) the
transferor Lender thereunder shall, to the extent provided in such Commitment Transfer Supplement,
be released from its obligations under this Agreement, the Commitment Transfer Supplement creating
a novation for that purpose. Such Commitment Transfer Supplement shall be deemed to amend this
Agreement to the extent, and only to the extent, necessary to reflect the addition of

90

 

such Purchasing Lender and the resulting adjustment of the Commitment Percentages arising from the
purchase by such Purchasing Lender of all or a portion of the rights and obligations of such
transferor Lender under this Agreement and the Other Documents. Borrower hereby consents to the
addition of such Purchasing Lender and the resulting adjustment of the Commitment Percentages
arising from the purchase by such Purchasing Lender of all or a portion of the rights and
obligations of such transferor Lender under this Agreement and the Other Documents. Borrower shall
execute and deliver such further documents and do such further acts and things in order to
effectuate the foregoing.

          (d) Agent shall maintain at its address a copy of each Commitment Transfer Supplement
delivered to it and a register (the “Register”) for the recordation of the names and addresses of
each Lender and the outstanding principal, accrued and unpaid interest and other fees due
hereunder. The entries in the Register shall be conclusive, in the absence of manifest error, and
Borrower, Agent and Lenders may treat each Person whose name is recorded in the Register as the
owner of the Advance recorded therein for the purposes of this Agreement. The Register shall be
available for inspection by Borrower or any Lender at any reasonable time and from time to time
upon reasonable prior notice. Agent shall receive a fee in the amount of $3,500 payable by the
applicable Purchasing Lender upon the effective date of each transfer or assignment to such
Purchasing Lender.

          (e) Borrower authorizes each Lender to disclose to any Transferee and any prospective
Transferee any and all financial information in such Lender’s possession concerning Borrower which
has been delivered to such Lender by or on behalf of Borrower pursuant to this Agreement or in
connection with such Lender’s credit evaluation of Borrower.

     16.4. Application of Payments. Agent shall have the continuing and exclusive right to
apply or reverse and re-apply any payment and any and all proceeds of Collateral to any portion of
the Obligations. To the extent that Borrower makes a payment or Agent or any Lender receives any
payment or proceeds of the Collateral for Borrower’s benefit, which are subsequently invalidated,
declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, debtor
in possession, receiver, custodian or any other party under any bankruptcy law, common law or
equitable cause, then, to such extent, the Obligations or part thereof intended to be satisfied
shall be revived and continue as if such payment or proceeds had not been received by Agent or such
Lender.

     16.5. Indemnity. Borrower shall indemnify Agent, each Lender and each of their
respective officers, directors, Affiliates, attorneys, employees and agents from and against any
and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses and disbursements of any kind or nature whatsoever (including fees and disbursements of
counsel) which may be imposed on, incurred by, or asserted against Agent or any Lender in any claim,
litigation, proceeding or investigation instituted or conducted by any Governmental Body or
instrumentality or any other Person with respect to any aspect of, or any transaction contemplated
by, or referred to in, or any matter related to, this Agreement or the Other Documents, whether or
not Agent or any Lender is a party thereto, except to the extent that any of the foregoing arises
out of the willful misconduct of the party being indemnified (as determined by a court of competent
jurisdiction in a final and non-appealable judgment). Without limiting the generality of the
foregoing, this indemnity shall extend to any liabilities,

91

 

obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses and disbursements of any kind or nature whatsoever
(including fees and disbursements of counsel) asserted against or incurred by any of the
indemnitees described above in this Section 16.5 by any Person under any Environmental Laws or
similar laws by reason of Borrower’s or any other Person’s failure to comply with laws applicable
to solid or hazardous waste materials, including Hazardous Substances and Hazardous Waste, or other
Toxic Substances. Additionally, if any taxes (excluding taxes imposed upon or measured solely by
the net income of Agent and Lenders, but including any intangibles taxes, stamp tax, recording tax
or franchise tax) shall be payable by Agent, Lenders or Borrower on account of the execution or
delivery of this Agreement, or the execution, delivery, issuance or recording of any of the Other
Documents, or the creation or repayment of any of the Obligations hereunder, by reason of any
Applicable Law now or hereafter in effect, Borrower will pay (or will promptly reimburse Agent and
Lenders for payment of) all such taxes, including interest and penalties thereon, and will
indemnify and hold the indemnitees described above in this Section 16.5 harmless from and against
all liability in connection therewith.

     16.6. Notice. Any notice or request hereunder may be given to Borrower or to Agent or
any Lender at their respective addresses set forth below or at such other address as may hereafter
be specified in a notice designated as a notice of change of address under this Section. Any
notice, request, demand, direction or other communication (for purposes of this Section 16.6 only,
a “Notice”) to be given to or made upon any party hereto under any provision of this Loan Agreement
shall be in writing (which includes by means of electronic transmission (i.e., “e-mail”) or
facsimile transmission in accordance with this Section 16.6. Any such Notice must be delivered to
the applicable parties hereto at the addresses and numbers set forth under their respective names
on Section 16.6 hereof or in accordance with any subsequent unrevoked Notice from any such party

          (b) If given by mail, four days after such Notice is deposited with the United States Postal
Service, with first-class postage prepaid, return receipt requested;

     16.7. Survival. The obligations of Borrower under Sections 2.2(f), 3.7, 3.8, 3.9,
4.19(h), and 15.5 and the obligations of Lenders under Section 14.7, shall survive termination of
this Agreement and the Other Documents and payment in full of the Obligations the greater of a
period of five (5) years from the Closing Date, or the expiration of any applicable statutes of
limitation, except with respect to any indemnification provisions contained herein, in which case
such provisions will survive indefinitely.

     16.8. Severability. If any part of this Agreement is contrary to, prohibited by, or
deemed invalid under Applicable Laws or regulations, such provision shall be inapplicable and
deemed omitted to the extent so contrary, prohibited or invalid, but the remainder hereof shall not
be invalidated thereby and shall be given effect so far as possible.

     16.9. Expenses. All costs and expenses including reasonable attorneys’ fees
(including the allocated costs of in house counsel) and disbursements incurred by Agent on its
behalf or on behalf of Lenders and Lenders (a) in all efforts made to enforce payment of any
Obligation or effect collection of any Collateral, or (b) in connection with the entering into,
modification, amendment, administration and enforcement of this Agreement or any consents or
waivers hereunder and all related agreements, documents and instruments, or (c) in instituting,
maintaining, preserving, enforcing and foreclosing on Agent’s security interest in or Lien on any
of the Collateral, or maintaining, preserving or enforcing any of Agent’s or any Lender’s rights
hereunder and under all related agreements, documents and instruments, whether through

94

 

judicial
proceedings or otherwise, or (d) in defending or prosecuting any actions or proceedings arising out
of or relating to Agent’s or any Lender’s transactions with Borrower, or (e) in connection with any
advice given to Agent or any Lender with respect to its rights and obligations under this Agreement
and all related agreements, documents and instruments, may be charged to Borrower’s Account and
shall be part of the Obligations.

     16.10. Injunctive Relief. Borrower recognizes that, in the event Borrower fails to
perform, observe or discharge any of its obligations or liabilities under this Agreement, or
threatens to fail to perform, observe or discharge such obligations or liabilities, any remedy at
law may prove to be inadequate relief to Lenders; therefore, Agent, if Agent so requests, shall be
entitled to temporary and permanent injunctive relief in any such case without the necessity of
proving that actual damages are not an adequate remedy.

     16.11. Damages. Neither party to this Agreement, nor any agent or attorney for any of
them, shall be liable to any other party (or any Affiliate of any such Person) for indirect,
punitive, exemplary or consequential damages arising from any breach of contract, tort or other
wrong relating to the establishment, administration or collection of the Obligations or as a result
of any transaction contemplated under this Agreement or any Other Document; provided that nothing
contained in this paragraph shall be construed to limit in any way whatsoever Lenders’ rights under
this Agreement, whether at law, equity, or otherwise.

     16.12. Captions. The captions at various places in this Agreement are intended for
convenience only and do not constitute and shall not be interpreted as part of this Agreement.

     16.13. Counterparts; Facsimile Signatures. This Agreement may be executed in any
number of and by different parties hereto on separate counterparts, all of which, when so executed,
shall be deemed an original, but all such counterparts shall constitute one and the same agreement.
Any signature delivered by a party by facsimile or scanned email transmission shall be deemed to
be an original signature hereto.

     16.14. Construction. The parties acknowledge that each party and its counsel have
reviewed this Agreement and that the normal rule of construction to the effect that any ambiguities
are to be resolved against the drafting party shall not be employed in the interpretation of this
Agreement or any amendments, schedules or exhibits thereto.

     16.15. Confidentiality; Sharing Information. Agent, each Lender and each Transferee
shall hold all non-public information obtained by Agent, such Lender or such Transferee pursuant to
the requirements of this Agreement in accordance with Agent’s, such Lender’s and such Transferee’s
customary procedures for handling confidential information of this nature; provided, however,
Agent, each Lender and each Transferee may disclose such confidential information (a) to its
examiners, Affiliates, outside auditors, counsel and other professional advisors, (b) to Agent, any
Lender or to any prospective Transferees, and (c) as required or requested by any Governmental Body
or representative thereof or pursuant to legal process; provided, further that (i) unless
specifically prohibited by Applicable Law or court order, Agent, each Lender and each Transferee
shall use its reasonable best efforts prior to disclosure thereof, to notify Borrower of the
applicable request for disclosure of such non-public information (A) by a Governmental Body or
representative thereof (other than any such request in connection with

95

 

an examination of the
financial condition of a Lender or a Transferee by such Governmental Body) or (B) pursuant to legal
process and (ii) in no event shall Agent, any Lender or any Transferee be obligated to return any
materials furnished by Borrower other than those documents and instruments in possession of Agent
or any Lender in order to perfect its Lien on the Collateral once the Obligations have been paid in
full and this Agreement has been terminated. Borrower acknowledges that from time to time financial
advisory, investment banking and other services may be offered or provided to Borrower or one or
more of its Affiliates (in connection with this Agreement or otherwise) by any Lender or by one or
more Subsidiaries or Affiliates of such Lender and Borrower hereby authorizes each Lender to share
any information delivered to such Lender by Borrower and its Subsidiaries pursuant to this
Agreement, or in connection with the decision of such Lender to enter into this Agreement, to any
such Subsidiary or Affiliate of such Lender, it being understood that any such Subsidiary or
Affiliate of any Lender receiving such information shall be bound by the provisions of this Section
16.15 as if it were a Lender hereunder. Such authorization shall survive the repayment of the
other Obligations and the termination of this Agreement.

     16.16. Publicity. Borrower and each Lender hereby authorizes Agent to make
appropriate announcements of the financial arrangement entered into among Borrower, Agent and
Lenders, including announcements which are commonly known as tombstones, in such publications and
to such selected parties as Agent shall in its sole and absolute discretion deem appropriate.

     16.17. Certifications From Banks and Participants; US PATRIOT Act. Each Lender or
assignee or participant of a Lender that is not incorporated under the
Laws of the United States of America 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
supervision 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
USA PATRIOT Act and the applicable regulations: (1) within 10 days after the Closing Date, and (2)
as such other times as are required under the USA PATRIOT Act.

          This AMENDMENT TO MEMBERSHIP INTEREST SALE AGREEMENT (the “Amendment”) is made and
entered into as of April 28, 2005 by and between K 3 Sherwood, LLC, an Arizona limited liability
company (“Seller”) and Columbia Equity, LP, a Virginia limited partnership
(“Purchaser”) with reference to the following facts:

RECITALS:

	 	A.  	Seller and Purchaser have entered into that certain Membership Interest Sale
Agreement for a membership interest in Holualoa/Carr Capital Sherwood, LLC, dated
January 31, 2005 (the “Contract”);
	 
	 	B.  	Seller and Purchaser have mutually agreed upon a hypothetical sale of the
Property (as defined in the Contract) for a sale price of Fourteen Million Six Hundred
Thousand Dollars ($14,600,000);
	 
	 	C.  	Seller and Purchaser have mutually agreed that the Contract shall terminate if
the Closing (as defined in the Contract) does not occur prior to March 31, 2005
pursuant to the terms of the Contract; and
	 
	 	D.  	Seller and Purchaser desire to amend the Contract as described below.

          NOW, THEREFORE, for and in consideration of the agreements and obligations hereinafter set
forth and other good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged by the parties hereto, Seller and Purchaser agree as follows:

TERMS

	1.  	Increase of Sale Price. Seller and Purchaser hereby agree to amend Section 1.2 of
the Contract to provide as follows:
	 
	   	The purchase price (the “Purchase Price”) for which Seller agrees to sell and assign
the Membership Interest to Purchaser, and which Purchaser agrees to pay to Seller, subject
to the terms of this Agreement, shall be equal to the amount of Net Cash Flow (as such term
is defined in the LLC Operating Agreement) that Seller would be entitled to receive pursuant
to Section 3.1 of the LLC Operating Agreement upon a hypothetical sale of the Property for a
sale price of Sixteen Million Dollars ($16,000,000) less the principal of and accrued
interest on the mortgage loan secured by the Property (the “Mortgage Loan”).
	 
	2.  	Extension of Closing Date. Seller and Purchaser hereby agree to amend Sections
3.1(g) and 3.2(g) of the Contract to provide as follows:
	 
	   	The Closing shall have occurred on or prior to July 31, 2005.

 

 

Seller and Purchaser hereby agree to amend Section 4.1 of the Contract to provide as follows:

	 	   	The consummation and closing (the “Closing”) of the transactions
contemplated under this Agreement shall take place at the offices of Hunton &
Williams LLP, Washington, D.C., or such other place as is mutually agreeable to the
parties, on the date of the closing of the IPO (the “Closing Date”), or as
otherwise set by agreement of the parties; provided, however, that this Agreement
shall terminate if Closing does not occur prior to July 31, 2005.
	 
	 	3.  	Ratification. Except as modified by this Amendment, the Contract remains in full
force and effect.
	 
	 	4.  	Counterparts. This Amendment may be executed in multiple counterparts, each of which
shall be deemed an original, and all of which, taken together, shall constitute one and the
same instrument.

 

 

     IN WITNESS WHEREOF, the parties hereto have executed this Amendment as of the date first set
forth above.
