Rocky Mount, NC 27804

 

Dear David:

 

We are excited to hear that you have plans to potentially open a paintball manufacturing facility in Rocky Mount that will employ up to 25 new workers and invest $2 million in a new building, machinery, and equipment. We understand that Turn-Key Contractors will build a facility to your specifications and lease it to you.

To help facilitate your decision to locate the paintball manufacturing facility in Rocky Mount, we offer the following incentives in addition to our peerless local business (climate:

1.          We will increase the local cash incentive $500 per new job for the 25 positions, in addition to the original 75 job creation offer, which will in effect increase the cash incentive from $37,500 to $50,000. This cash incentive will be disbursed to you upon material proof of job creation for all 100 jobs. A new inducement agreement outlining the new job creation goals must be signed prior any announcement or commencement of the project.

2.          We will coordinate with Donna Phillips to apply for a $25,000 One North Carolina Fund grant. The availability of this grant depends on approval by the state and your company meeting specific wage, health insurance, environmental, and NAICS requirements. Since the site you are examining in Nash County is within a Special Development Zone, the wage requirement is reduced to an overall average salary of $14.30 per hour. This requirement includes wages for all full time employees including hourly, salary, and management positions. We will need your assistance in obtaining the necessary information for the grant application process. The state of North Carolina does not allow tax abatements, so we are pursuing this avenue instead of the local tax route.

3.          We have attached an outline from Donna Phillips of the potential William S. Lee Tax Credits your company may be eligible for between RTC and the paintball manufacturing operation. Your accountant can help you apply for these tax credits through the state. Based on your operation being located in a Special Development Zone and the overall creation of 100 jobs, you may receive up to $670,000 in tax credits over a seven-year period. As you may know, tax credits on a given year can be taken against up to 50% of the tax Corporate Income or Franchise tax burden.

 

 

MI-166106 v1 0436935-0201

 

 

 

4.          We will coordinate with you, the Employment Security Commission, and the Upper Coastal Plains Council of Governments to obtain any available federal grants or credits for hiring eligible dislocated and unemployed workers. Typically, these programs offer $1,000 per new job created.

5.          Nash Community College offers the New and Expanding Industry Training program to companies that add at least 12 new employees at one time to their operation. This award winning program will train your employees to the level and specification needed to begin the operation. Trainers can visit other similar operations and utilize your equipment to derive a program that will benefit your company. These services are provided at little or no cost to the company.

We are delighted to work with you on this project. Once you have read this letter, I suggest that we get together with Donna Phillips, the Upper Coastal Plains Council of Governments, and Nash Community College to further explore what we can do to lower your upfront costs and bring this project to fruition.

 

Sincerely,

 

 

Jeremy Stratton, Vice President

Multicurrency Credit Agreement

This Multicurrency Credit Agreement is entered into as of March 28, 2005, by and among
Cleveland-Cliffs Inc, an Ohio corporation (the “Borrower”), the various institutions from time to
time party to this Agreement, as Lenders, Fifth Third Bank, an Ohio banking corporation, as
Administrative Agent and L/C Issuer, and Fleet National Bank, a Bank of America company, as
Syndication Agent.

The Borrower has requested, and the Lenders have agreed to extend, certain credit facilities
on the terms and conditions of this Agreement. In consideration of the mutual agreements set forth
in this Agreement, the parties to this Agreement agree as follows:

Section 1. Definitions; Interpretation.

Section 1.1. Definitions. The following terms when used herein shall have the following
meanings:

“Acquisition” means any transaction or series of related transactions for the purpose of or
resulting, directly or indirectly, in (a) the acquisition of all or substantially all of the assets
of a Person, or of any business or division of a Person, (b) the acquisition of in excess of 50% of
the capital stock, partnership interests, membership interests or equity of any Person (other than
a Person that is a Subsidiary), or (c) a merger or consolidation or any other combination with
another Person (other than a Person that is a Subsidiary), provided that the Borrower or the
Subsidiary is the surviving entity.

“Adjusted LIBOR” means, for any Borrowing of Eurocurrency Loans, a rate per annum equal to the
quotient of (i) LIBOR, divided by (ii) one minus the Reserve Percentage.

“Administrative Agent” means Fifth Third Bank, an Ohio banking corporation, as contractual
representative for itself and the other Lenders and any successor pursuant to Section 9.7 hereof.

“Administrative Agent’s Quoted Rate” is defined in Section 2.10(c) hereof.

“Administrative Questionnaire” means an Administrative Questionnaire in a form supplied by the
Administrative Agent.

“Affiliate” means any Person directly or indirectly controlling or controlled by, or under
direct or indirect common control with, another Person. A Person shall be deemed to control
another Person for purposes of this definition if such Person possesses, directly or indirectly,
the power to direct, or cause the direction of, the management and policies of the other Person,
whether through the ownership of voting securities, common directors, trustees or officers, by
contract or otherwise; provided that, in any event for purposes of this definition, any Person that
owns, directly or indirectly, 30% or more of the securities having the ordinary voting power for
the election of directors or governing body of a corporation or 30% or more of the partnership or
other ownership interests of any other Person (other than as a limited partner of such other
Person) will be deemed to control such corporation or other Person.

“Agreement” means this Multicurrency Credit Agreement, as the same may be amended, modified,
restated or supplemented from time to time pursuant to the terms hereof.

“Alternative Currency” means any of Australian dollars and Canadian dollars, and any other
currency approved by the Administrative Agent, in each case for so long as such currency is readily
available to all the Lenders and is freely transferable and freely convertible to U.S. Dollars and
the Dow Jones Telerate Service or Reuters Monitor Money Rates Service (or any successor to either)
reports a LIBOR for such currency for interest periods of one, two, three, six and twelve calendar
months; provided that if any Lender provides written notice to the Borrower (with a copy to the
Administrative Agent) that any currency control or other exchange regulations are imposed in the
country in which any such Alternative Currency is issued and that in the reasonable opinion of such
Lender funding a Loan in such currency is unlawful or subject to unreasonably burdensome legal
restrictions, then such currency shall cease to be an Alternative Currency hereunder until such
time as all the Lenders reinstate such country’s currency as an Alternative Currency.

“Applicable Margin” means, with respect to Loans, Reimbursement Obligations, and the
commitment fees and letter of credit fees payable under Section 2.12 hereof, until the first
Pricing Date, the rates per annum shown opposite Level III below, and thereafter from one Pricing
Date to the next the Applicable Margin means the rates per annum determined in accordance with the
following schedule:

	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 
	 	 	 	 	 	 	Applicable Margin	 	Applicable Margin

For purposes hereof, the term “Pricing Date” means, for any fiscal quarter of the Borrower
ending on or after March 31, 2005, the date on which the Administrative Agent is in receipt of the
Borrower’s most recent financial statements (and, in the case of the year-end financial statements,
audit report) for the fiscal quarter then ended, pursuant to Section 6.1 hereof. The Applicable
Margin shall be established based on the Total Funded Debt to EBITDA ratio for the most recently
completed fiscal quarter and the Applicable Margin established on a Pricing Date shall remain in
effect until the next Pricing Date. If the Borrower has not delivered its financial statements by
the date such financial statements (and, in the case of the year-end financial statements, audit
report) are required to be delivered under Section 6.1 hereof, until such financial statements and
audit report are delivered, the Applicable Margin shall be the highest Applicable Margin (i.e., the
Total Funded Debt to EBITDA ratio shall be deemed to be greater than 1.50 to 1.0). If the Borrower
subsequently delivers such financial statements before the next Pricing Date, the Applicable Margin
established by such late delivered financial statements shall take effect from the date of delivery
until the next Pricing Date. In all other circumstances, the Applicable Margin established by such
financial statements shall be in effect from the Pricing Date that occurs immediately after the end
of the fiscal quarter covered by such financial statements until the next Pricing Date. Each
determination of the Applicable Margin made by the Administrative Agent in accordance with the
foregoing shall be conclusive and binding on the Borrower and the Lenders absent manifest error.

“Application” is defined in Section 2.2(b) hereof.

“Approved Fund” means any Fund that is administered or managed by (a) a Lender, (b) an
Affiliate of a Lender or (c) an entity or an Affiliate of an entity that administers or manages a
Lender.

“Assignment and Assumption” means an assignment and assumption entered into by a Lender and an
Eligible Assignee (with the consent of any party whose consent is required by Section 10.10), and
accepted by the Administrative Agent, in substantially the form of Exhibit G or any other form
approved by the Administrative Agent.

“Authorized Representative” means those persons shown on the list of officers provided by the
Borrower pursuant to Section 3.2 hereof or on any update of any such list provided by the Borrower
to the Administrative Agent, or any further or different officers of the Borrower so named by any
Authorized Representative of the Borrower in a written notice to the Administrative Agent.

“Base Rate” means for any day the greater of: (i) the rate of interest announced by the
Administrative Agent from time to time as its “prime rate” as in effect on such day, with any
change in the Base Rate resulting from a change in said prime rate to be effective as of the date
of the relevant change in said prime rate (it being acknowledged that such rate may not be the
Administrative Agent’s best or lowest rate) and (ii) the sum of (x) the Federal Funds Rate, plus
(y) 1/2 of 1%.

“Borrowing” means the total of Loans of a single type advanced, continued for an additional
Interest Period, or converted from a different type into such type by the Lenders on a single date
and, in the case of Eurocurrency Loans, for a single Interest Period. Borrowings of Loans are made
and maintained ratably from each of the Lenders according to their Percentages. A Borrowing is
“advanced” on the day Lenders advance funds comprising such Borrowing to the Borrower, is
“continued” on the date a new Interest Period for the same type of Loans commences for such
Borrowing, and is “converted” when such Borrowing is changed from one type of Loans to the other,
all as requested by the Borrower pursuant to Section 2.4(a) hereof.

and foreign exchange markets are open for business in the city where disbursements of or payments
on such Loan are to be made and, if such Alternative Currency is the euro or any national currency
of a nation that is a member of the European Economic and Monetary Union, which is a TARGET
Settlement Day.

“Capital Expenditures” means, with respect to any Person for any period, the aggregate amount
of all expenditures (whether paid in cash or accrued as a liability) by such Person during that
period for the acquisition or leasing (pursuant to a Capital Lease) of fixed or capital assets or

“Capital Lease” means any lease of Property which in accordance with GAAP is required to be

Section 1.2. Interpretation. The foregoing definitions are equally applicable to both the
singular and plural forms of the terms defined. The words “hereof”, “herein”, and “hereunder” and
words of like import when used in this Agreement shall refer to this Agreement as a whole and not
to any particular provision of this Agreement. All references to time of day herein are references
to Cincinnati, Ohio, time unless otherwise specifically provided. Where the character or amount of
any asset or liability or item of income or expense is required to be determined or any
consolidation or other accounting computation is required to be made for the purposes of this
Agreement, it shall be done in accordance with GAAP except where such principles are inconsistent
with the specific provisions of this Agreement. All terms that are used in this Agreement which

to be in compliance with any financial covenant hereunder nor out of compliance with any financial
covenant hereunder if such state of compliance or noncompliance, as the case may be, would not
exist but for the occurrence of a change in accounting principles after the date hereof.

Section 2. The Credit Facilities.

Section 2.1. Revolving Credit Commitments. Prior to the Termination Date, each Lender
severally and not jointly agrees, subject to the terms and conditions hereof, to make revolving
loans (each individually a “Revolving Loan” and, collectively, the “Revolving Loans”) in U.S.
Dollars and Alternative Currencies to the Borrower from time to time in an aggregate outstanding
Original Dollar Amount up to the amount of such Lender’s Commitment; provided, however, the sum of
the (i) aggregate Original Dollar Amount of Revolving Loans, (ii) the aggregate principal amount of
Swing Loans and (iii) the aggregate principal amount of L/C Obligations at any time outstanding
shall not exceed the sum of all Commitments in effect at such time. Each Borrowing of Revolving
Loans shall be made ratably by the Lenders in proportion to their respective Percentages. As
provided in Section 2.4(a), and subject to the terms hereof, the Borrower may elect that each
Borrowing of Revolving Loans denominated in U.S. Dollars be either Base Rate Loans or Eurocurrency
Loans. All Loans denominated in an Alternative Currency shall be Eurocurrency Loans. Revolving
Loans may be repaid and reborrowed before the Termination Date, subject to the terms and conditions
hereof.

Section 2.2. Letters of Credit. (a) General Terms. Subject to the terms and conditions
hereof, as part of the Revolving Credit, the L/C Issuer shall issue standby letters of credit (each
a “Letter of Credit”) for the Borrower’s account, and for the benefit of the Borrower and each
Material Subsidiary that has complied with Section 4.2 hereof, in an aggregate undrawn face amount
up to the L/C Sublimit; provided, however, the sum of the (i) aggregate Original Dollar Amount of
Revolving Loans, (ii) the aggregate principal amount of Swing Loans and (iii) the aggregate
principal amount of L/C Obligations at any time outstanding shall not exceed the sum of all
Commitments in effect at such time. Each Lender shall be obligated to reimburse the L/C Issuer for
such Lender’s Percentage of the amount of each drawing under a Letter of Credit and, accordingly,
each Letter of Credit shall constitute usage of the Commitment of each Lender pro rata in an amount
equal to its Percentage of the L/C Obligations then outstanding.

(b) Applications. At any time before the Termination Date, the L/C Issuer shall, at the
request of the Borrower, issue one or more Letters of Credit in U.S. Dollars, in form and substance
acceptable to the L/C Issuer, with expiration dates no later than the earlier of 12 months from the
date of issuance (or which are cancelable not later than 12 months from the date of issuance and
each renewal) or 30 days prior to the Termination Date, in an aggregate face amount as set forth
above, upon the receipt of a duly executed application for the relevant Letter of Credit in the
form then customarily prescribed by the L/C Issuer for the Letter of Credit requested (each an
“Application”). Notwithstanding anything contained in any Application to the contrary: (i) the
Borrower shall pay fees in connection with each Letter of Credit as set forth in Section 2.12(b)
hereof, and (ii) if the L/C Issuer is not timely reimbursed for the amount of any drawing under a
Letter of Credit on the date such drawing is paid, the Borrower’s obligation to reimburse the L/C
Issuer for the amount of such drawing shall bear interest (which the Borrower hereby promises to
pay) from and after the date such drawing is paid at a rate per annum equal to the sum of 2.0% plus
the Applicable Margin plus the Base Rate from time to time in effect (computed on the basis of a
year of 360 days and the actual number of days elapsed). Without limiting the foregoing, the L/C
Issuer’s obligation to issue, amend or extend the expiration date of a Letter of Credit is subject
to the terms or conditions of this Agreement (including the conditions set forth in Section 3.1 and
the other terms of this Section 2.2).

(c) The Reimbursement Obligations. Subject to Section 2.2(b) hereof, the obligation of the
Borrower to reimburse the L/C Issuer for all drawings under a Letter of Credit (a “Reimbursement
Obligation”) shall be governed by the Application related to such Letter of Credit and this
Agreement, except that reimbursement shall be made by no later than 12:00 Noon (Cincinnati time) on
the date when each drawing is to be paid if the Borrower has been informed of such drawing by the
L/C Issuer on or before 11:30 a.m. (Cincinnati time) on the date when such drawing is to be paid
or, if notice of such drawing is given to the Borrower after 11:30 a.m. (Cincinnati time) on the
date when such drawing is to be paid, by 12:00 noon on the following Business Day in immediately
available funds at the Administrative Agent’s principal office in Cincinnati, Ohio or such other
office as the Administrative Agent may designate in writing to the Borrower, and the Administrative
Agent shall thereafter cause to be distributed to the L/C Issuer such amount(s) in like funds;
provided that, with respect to drawings for which notice is given after 11:30 a.m. (Cincinnati
time), if the Borrower does not reimburse the L/C issuer on the date such drawing is paid, the
Borrower shall pay to the L/C Issuer interest on such Reimbursement Obligation from the date such
drawing is paid until the date such Reimbursement Obligation is due at a rate per annum (computed
on the basis of 360 days and the actual days elapsed) equal to the Applicable Margin plus the Base
Rate from time to time in effect. If the Borrower does not make any such reimbursement payment on
the date due and the Participating Lenders fund their participations in the manner set forth in
Section 2.2(d) below, then all payments thereafter received by the Administrative Agent in
discharge of any of the relevant Reimbursement Obligations shall be distributed in accordance with
Section 2.2(d) below.

The obligations of the Borrower under this Section 2.2 shall be absolute, irrevocable and
unconditional under any and all circumstances and shall not be subject to any set-off, counterclaim
or defense to payment that the Borrower may have or has had against the the L/C Issuer, the
Administrative Agent, any Lender or any other Person. Without limiting the generality of the
foregoing, such obligations shall not be affected by any Default or Event of Default, and each
payment by a Borrower under this Section 2.2 shall be made without any offset, abatement,
withholding or reduction whatsoever.

(d) The Participating Interests. Each Lender (other than the Lender acting as L/C Issuer)
severally and not jointly agrees to purchase from the L/C Issuer, and the L/C Issuer hereby agrees
to sell to each such Lender (a “Participating Lender”), an undivided participating interest (a
“Participating Interest”) to the extent of its Percentage in each Letter of Credit issued by, and
each Reimbursement Obligation owed to, the L/C Issuer. Upon Borrower’s failure to pay any
Reimbursement Obligation on the date and at the time required, or if the L/C Issuer is required at
any time to return to the Borrower or to a trustee, receiver, liquidator, custodian or other Person
any portion of any payment of any Reimbursement Obligation, each Participating Lender shall, not
later than the Business Day it receives a certificate in the form of Exhibit A hereto from the L/C
Issuer (with a copy to the Administrative Agent) to such effect, if such certificate is received
before 1:00 p.m. (Cincinnati time), or not later than 1:00 p.m. (Cincinnati time) the following
Business Day, if such certificate is received after such time, pay to the Administrative Agent for
the account of the L/C Issuer an amount equal to such Participating Lender’s Percentage of such
unpaid Reimbursement Obligation together with interest on such amount accrued from the date the L/C
Issuer made the related payment to the date of such payment by such Participating Lender at a rate
per annum equal to: (i) from the date the L/C Issuer made the related payment to the date 2
Business Days after payment by such Participating Lender is due hereunder, the Federal Funds Rate
for each such day and (ii) from the date 2 Business Days after the date such payment is due from
such Participating Lender to the date such payment is made by such Participating Lender, the Base
Rate in effect for each such day. Each such Participating Lender shall, after making its
appropriate payment, be entitled to receive its Percentage of each payment received in respect of
the relevant Reimbursement Obligation and of interest paid thereon, with the L/C Issuer retaining
its Percentage thereof as a Lender hereunder.

The several obligations of the Participating Lenders to the L/C Issuer under this Section 2.2
shall be absolute, irrevocable and unconditional under any and all circumstances and shall not be
subject to any set-off, counterclaim or defense to payment which any Participating Lender may have
or has had against the Borrower, the L/C Issuer, the Administrative Agent, any Lender or any other
Person. Without limiting the generality of the foregoing, such obligations shall not be affected
by any Default or Event of Default or by any reduction or termination of the Commitment of any
Lender, and each payment by a Participating Lender under this Section 2.2 shall be made without any
offset, abatement, withholding or reduction whatsoever.

(e) Indemnification. The Participating Lenders shall, to the extent of their respective
Percentages, indemnify the L/C Issuer (to the extent not reimbursed by the Borrower) against any
cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or
liability (except such as result from the L/C Issuer’s gross negligence or willful misconduct) that
the L/C Issuer may suffer or incur in connection with any Letter of Credit issued by it. The
obligations of the Participating Lenders under this Section 2.2(e) and all other parts of this
Section 2.2 shall survive termination of this Agreement and of all Applications, Letters of Credit,
and all drafts and other documents presented in connection with drawings thereunder.

(f) Manner of Requesting a Letter of Credit. The Borrower shall provide at least five (5)
Business Days’ advance written notice (or such shorter period of time as agreed to by the L/C
Issuer) to the Administrative Agent of each request for the issuance of a Letter of Credit, each
such notice to be accompanied by a properly completed and executed Application for the requested
Letter of Credit and, in the case of an extension or an increase in the amount of a Letter of
Credit, a written request therefor, in a form acceptable to the Administrative Agent and the L/C
Issuer, in each case, together with the fees called for by this Agreement. The Administrative
Agent shall promptly notify the L/C Issuer of the Administrative Agent’s receipt of each such
notice and the L/C Issuer shall promptly notify the Administrative Agent and the Lenders of the
issuance of a Letter of Credit.

Section 2.3. Applicable Interest Rates. (a) Base Rate Loans. Each Base Rate Loan made or
maintained by a Lender shall bear interest (computed on the basis of a year of 365 or 366 days, as
applicable, and the actual days elapsed) under the Notes on the unpaid principal amount of such
Loan from the date such Loan is advanced or created by conversion from a Eurocurrency Loan until
maturity (whether by acceleration or otherwise) at a rate per annum equal to the sum of the
Applicable Margin plus the Base Rate from time to time in effect, payable in arrears on the last
Business Day of each month and at maturity (whether by acceleration or otherwise).

(b) Eurocurrency Loans. Each Eurocurrency Loan made or maintained by a Lender shall bear
interest under the Notes during each Interest Period it is outstanding (computed on the basis of a
year of 360 days and actual days elapsed) on the unpaid principal amount thereof from the date such
Loan is advanced, continued or created by conversion from a Base Rate Loan until maturity (whether
by acceleration or otherwise) at a rate per annum equal to the sum of the Applicable Margin plus
the Adjusted LIBOR applicable for such Interest Period, payable in arrears on the last day of the
Interest Period and at maturity (whether by acceleration or otherwise), and, if the applicable
Interest Period is longer than three months, on each day occurring every three months after the
commencement of such Interest Period.

(c) Default Rate. While any Event of Default exists or after acceleration, the Borrower shall
pay interest under the Notes (after as well as before entry of judgment thereon to the extent
permitted by law) on the principal amount of all Loans owing by it at a rate per annum equal to:

(i) for any Base Rate Loan or any Swing Loan bearing interest at the Base Rate, the sum
of 2.0% per annum plus the Applicable Margin plus the Base Rate from time to time in effect;

(ii) for any Eurocurrency Loan denominated in U.S. Dollars, the sum of 2.0% plus the
rate of interest in effect thereon at the time of such Event of Default until the end of the
Interest Period applicable thereto and, thereafter, at a rate per annum equal to the sum of
2.0% plus the Applicable Margin for Base Rate Loans plus the Base Rate from time to time in
effect; and

(iii) for any Eurocurrency Loan denominated in an Alternative Currency, the sum of 2.0%
plus the rate of interest in effect thereon at the time of such Event of Default until the
end of the Interest Period applicable thereto and, thereafter, at a rate per annum equal to
the sum of (A) the Applicable Margin for Eurocurrency Loans plus (B) two percent (2%) plus
(C) the rate of interest per annum as determined in good faith by the Administrative Agent
(rounded upwards, if necessary, to the next higher 1/100,000 of 1%) at which overnight or
weekend deposits (or, if such amount due remains unpaid more than three Business Days, then
for such other period of time not longer than one month as the Administrative Agent may
elect in good faith) of the relevant Alternative Currency for delivery in immediately
available and freely transferable funds would be offered by the Administrative Agent to
major banks in the interbank market upon request of such major banks for the applicable
period as determined above and in an amount comparable to the unpaid principal amount of any
such Eurocurrency Loan (or, if the Administrative Agent is not placing deposits in such
currency in the interbank market, then the Administrative Agent’s cost of funds in such
currency for such period); and

provided, however, prior to acceleration, any increase in interest rates pursuant to this Section
shall be made at the election of the Administrative Agent, acting at the request or with the
consent of the Required Lenders, with written notice to the Borrower. While any Event of Default
exists or after acceleration, interest shall be paid on demand of the Administrative Agent at the
request or with the consent of the Required Lenders and shall be payable under the Notes.

(d) Rate Determinations. The Administrative Agent shall determine each interest rate
applicable to the Loans and the Reimbursement Obligations hereunder, and its determination thereof
shall be conclusive and binding except in the case of manifest error. The Original Dollar Amount
of each Eurocurrency Loan denominated in an Alternative Currency shall be determined or
redetermined, as applicable, effective as of the first day of each Interest Period applicable to
such Loan.

Section 2.4. Manner of Borrowing Loans and Designating Currency and Applicable Interest Rates.
(a) Notice to the Administrative Agent. The Borrower shall give notice to the Administrative
Agent by no later than 12:00 noon (Cincinnati time): (i) at least four (4) Business Days before
the date on which the Borrower requests the Lenders to advance a Borrowing of Eurocurrency Loans
denominated in an Alternative Currency, (ii) at least 3 Business Days before the date on which the
Borrower requests the Lenders to advance a Borrowing of Eurocurrency Loans denominated in U.S.
Dollars and (iii) on the date the Borrower requests the Lenders to advance a Borrowing of Base Rate
Loans. The Loans included in each Borrowing shall bear interest initially at the type of rate
specified in such notice. Thereafter, the Borrower may from time to time elect to change or
continue the type of interest rate borne by each Borrowing or, subject to Section 2.5 hereof, a
portion thereof, as follows: (i) if such Borrowing is of Eurocurrency Loans, on the last day of
the Interest Period applicable thereto, the Borrower may continue part or all of such Borrowing as
Eurocurrency Loans or, if such Eurocurrency Loan is denominated in U.S. Dollars convert part or all
of such Borrowing into Base Rate Loans or (ii) if such Borrowing is of Base Rate Loans, on any
Business Day, the Borrower may convert all or part of such Borrowing into Eurocurrency Loans
denominated in U.S. Dollars for an Interest Period or Interest Periods specified by the Borrower.
The Borrower shall give all such notices requesting the advance, continuation or conversion of a
Borrowing to the Administrative Agent by telephone or telecopy (which notice shall be irrevocable
once given and, if by telephone, shall be promptly confirmed in writing), substantially in the form
attached hereto as Exhibit B (Notice of Borrowing) or Exhibit C (Notice of
Continuation/Conversion), as applicable, or in such other form acceptable to the Administrative
Agent. Notice of the continuation of a Borrowing of Eurocurrency Loans denominated in U.S. Dollars
for an additional Interest Period or of the conversion of part or all of a Borrowing of Base Rate
Loans into Eurocurrency Loans denominated in U.S. Dollars must be given by no later than 10:00 a.m.
(Cincinnati time) at least 3 Business Days before the date of the requested continuation or
conversion. Notices of the continuation of a Borrowing of Eurocurrency Loans denominated in an
Alternative Currency must be given no later than 12:00 noon (Cincinnati time) at least four (4)
Business Days before the requested continuation. All notices concerning the advance, continuation
or conversion of a Borrowing shall specify the date of the requested advance, continuation or
conversion of a Borrowing (which shall be a Business Day), the amount of the requested Borrowing to
be advanced, continued or converted, the type of Loans to comprise such new, continued or converted
Borrowing and, if such Borrowing is to be comprised of Eurocurrency Loans, the currency and
Interest Period applicable thereto. The Borrower agrees that the Administrative Agent may rely on
any such telephonic or telecopy notice given by any person the Administrative Agent in good faith
believes is an Authorized Representative without the necessity of independent investigation (the
Borrower hereby indemnifying the Agent from any liability or loss ensuing from such reliance) and,
in the event any such notice by telephone conflicts with any written confirmation, such telephonic
notice shall govern if the Administrative Agent has acted in reliance thereon.

(b) Notice to the Lenders. The Administrative Agent shall give prompt telephonic or telecopy
notice to each Lender of any notice from the Borrower received pursuant to Section 2.4(a) above
and, if such notice requests the Lenders to make Eurocurrency Loans, the Administrative Agent shall
give notice to the Borrower and each Lender of the interest rate applicable thereto promptly after
the Administrative Agent has made such determination and, if such Borrowing is denominated in an
Alternative Currency, shall give notice by such means to the Borrower and each Lender of the
Original Dollar Amount thereof.

(c) Borrower’s Failure to Notify; Automatic Continuations and Conversions. If the Borrower
fails to give proper notice of the continuation or conversion of any outstanding Borrowing of
Eurocurrency Loans denominated in U.S. Dollars before the last day of its then current Interest
Period within the period required by Section 2.4(a) or, whether or not such notice has been given,
one or more of the conditions set forth in Section 3.1 for the continuation or conversion of a
Borrowing of Eurocurrency Loans would not be satisfied, and such Borrowing is not prepaid in
accordance with Section 2.7(a), such Borrowing shall automatically be converted into a Borrowing of
Base Rate Loans. If the Borrower fails to give proper notice of the continuation of any
outstanding Borrowing of Eurocurrency Loans denominated in an Alternative Currency before the last
day of its then current Interest Period within the period required by Section 2.4(a) and has not
notified the Administrative Agent within the period required by Section 2.7(a) that it intends to
prepay such Borrowing, such Borrowing shall automatically be continued as a Borrowing of
Eurocurrency Loans in the same Alternative Currency with an Interest Period of one month. In the
event the Borrower fails to give notice pursuant to Section 2.4(a) of a Borrowing equal to the
amount of a Reimbursement Obligation and has not notified the Administrative Agent by 1:00 p.m.
(Cincinnati time) on the day such Reimbursement Obligation becomes due that it intends to repay
such Reimbursement Obligation through funds not borrowed under this Agreement, the Borrower shall
be deemed to have requested a Borrowing of Base Rate Loans under the Revolving Credit (or, at the
option of the Administrative Agent, under the Swing Line) on such day in the amount of the
Reimbursement Obligation then due, which Borrowing shall be applied to pay the Reimbursement
Obligation then due.

(d) Disbursement of Loans. Not later than 1:00 p.m. (Cincinnati time) on the date of any
requested advance of a new Borrowing, subject to Section 3 hereof, each Lender shall make available
its Loan comprising part of such Borrowing in funds immediately available at the principal office
of the Administrative Agent in Cincinnati, Ohio. The Administrative Agent shall make the proceeds
of each new Borrowing available to the Borrower at the Administrative Agent’s principal office in
Cincinnati, Ohio, except that if such Borrowing is denominated in an Alternative Currency each
Lender shall, subject to Section 3 hereof, make available its Loan comprising part of such
Borrowing at such account with such financial institution as the Administrative Agent has
previously specified in a notice to each Lender, in such funds as are then customary for the
settlement of international transactions in such currency and no later than such local time as is
necessary for such funds to be received and transferred to the Borrower for same day value on the
date of the Borrowing. The Administrative Agent shall make the proceeds of each new Borrowing
denominated in U.S. Dollars available to the Borrower at the Administrative Agent’s principal
office in Cincinnati, Ohio, by depositing such proceeds to the credit of the Borrower’s operating
account maintained with the Administrative Agent or as the Borrower and the Administrative Agent
may otherwise agree, and the Administrative Agent shall make the proceeds of each new Borrowing
denominated in an Alternative Currency available at such account with such financial institution as
the Administrative Agent has previously agreed to with the Borrower, in each case in the type of
funds received by the Administrative Agent from the Lenders.

(e) Administrative Agent Reliance on Lender Funding. Unless the Administrative Agent shall
have been notified by a Lender prior to (or, in the case of a Borrowing of Base Rate Loans, by 1:00
p.m. (Cincinnati time) on) the date on which such Lender is scheduled to make payment to the
Administrative Agent of the proceeds of a Loan (which notice shall be effective upon receipt) that
such Lender does not intend to make such payment, the Administrative Agent may assume that such
Lender has made such payment when due and the Administrative Agent, in reliance upon such
assumption may (but shall not be required to) make available to the Borrower the proceeds of the
Loan to be made by such Lender and, if any Lender has not in fact made such payment to the
Administrative Agent, such Lender shall, on demand, pay to the Administrative Agent the amount made
available to the Borrower attributable to such Lender together with interest thereon in respect of
each day during the period commencing on the date such amount was made available to the Borrower
and ending on (but excluding) the date such Lender pays such amount to the Administrative Agent at
a rate per annum equal to: (i) from the date the related advance was made by the Administrative
Agent to the date 2 Business Days after payment by such Lender is due hereunder, the Federal Funds
Rate for each such day, or, in the case of a Loan denominated in an Alternative Currency, the cost
to the Administrative Agent of funding the amount it advanced to fund such Lender’s Loan, as
determined by the Administrative Agent and (ii) from the date 2 Business Days after the date such
payment is due from such Lender to the date such payment is made by such Lender, the Base Rate in
effect for each such day or in the case of a Loan denominated in an Alternative Currency, the rate
established by Section 2.3(c)(iii) for Eurocurrency Loans denominated in such currency. If such
amount is not received from such Lender by the Administrative Agent immediately upon demand, the
requesting Borrower will, on demand, repay to the Administrative Agent the proceeds of the Loan
attributable to such Lender with interest thereon at a rate per annum equal to the interest rate
applicable to the relevant Loan, but without such payment being considered a payment or prepayment
of a Loan under Section 8.1 hereof so that such Borrower will have no liability under such Section
with respect to such payment.

Section 2.5. Minimum Borrowing Amounts; Maximum Eurocurrency Loans. Each Borrowing of Base
Rate Loans shall be in an amount not less than U.S. $100,000. Each Borrowing of Eurocurrency Loans
advanced, continued or converted under the Revolving Credit shall be in an amount not less than an
Original Dollar Amount of U.S. $1,000,000 or such greater amount in units of the relevant currency
as would have the Original Dollar Amount most closely approximating $100,000 or an integral
multiple thereof. Without the Administrative Agent’s consent, there shall not be more than five
(5) Borrowings of Eurocurrency Loans outstanding hereunder at any one time.

Section 2.6. Maturity of Revolving Loans. Each Revolving Loan and, without limiting the
effect of Section 2.10 hereof, Swing Loan, both for principal and interest, shall mature and become
due and payable by the Borrower on the Termination Date.

Section 2.7. Prepayments. (a) Voluntary. The Borrower may prepay without premium or penalty
(except as set forth in Section 8.1 below) and in whole or in part any Borrowing of (x)
Eurocurrency Loans denominated in U.S. Dollars at any time upon 3 Business Days prior notice by the
Borrower to the Administrative Agent, (y) Eurocurrency Loans denominated in an Alternative Currency
at any time upon 4 Business Days prior notice by the Borrower to the Administrative Agent, or (z)
Base Rate Loans, notice delivered by the Borrower to the Administrative Agent no later than 10:00
a.m. (Cincinnati time) on the date of prepayment (or, in any case, such shorter period of time then
agreed to by the Administrative Agent), such prepayment to be made by the payment of the principal
amount to be prepaid and, in the case of any Eurocurrency Loans or Swing Loans, accrued interest
thereon to the date fixed for prepayment plus any amounts due the Lenders under Section 8.1 hereof;
provided, however, the Borrower may not partially repay a Borrowing (i) if such Borrowing is of
Base Rate Loans, in a principal amount less than U.S. $100,000, (ii) if such Borrowing is of
Eurocurrency Loans denominated in U.S. Dollars, in a principal amount less than U.S. $1,000,000,
(iii) if such Borrowing is denominated in an Alternative Currency, an amount for which the U.S.
Dollar Equivalent is less than $1,000,000 and (iv) in each case, unless it is in an amount such
that the minimum amount required for a Borrowing pursuant to Section 2.5 remains outstanding.

(b) Mandatory. (i) The Borrower shall, on each date the Commitments are reduced pursuant to
Section 2.9, prepay the Revolving Loans and Swing Loans and, if necessary, prefund the L/C
Obligations by the amount, if any, necessary to reduce the sum of the aggregate principal amount of
Revolving Loans, Swing Loans and L/C Obligations then outstanding to the amount to which the
Commitments have been so reduced.

(ii) If at any time the sum of the aggregate Original Dollar Amount of the Revolving Loans,
Swing Loans and the L/C Obligations then outstanding shall be in excess of the Commitments then in
effect, the Borrower shall, within five days of such date and without notice or demand, pay over
the amount of the excess to the Administrative Agent for the account of the Lenders as and for a
mandatory prepayment on such Obligations, with each such prepayment first to be applied to the
Swing Loans then outstanding until payment in full thereof, with any remaining balance to be
applied to the Revolving Loans then outstanding until payment in full thereof, with any remaining
balance to be held by the Administrative Agent in the Collateral Account as security for the
Obligations owing with respect to the Letters of Credit.

(iii) Unless the Borrower otherwise directs, prepayments of Loans under this Section 2.7(b) in
U.S. Dollars shall be applied first to Borrowings of Base Rate Loans until payment in full thereof
with any balance applied to Borrowings of Eurocurrency Loans denominated in U.S. Dollars in the
order in which their Interest Periods expire and prepayments made in Alternative Currencies under
this Section 2.7(b) shall be applied to Borrowings in such Alternative Currency in the order in
which their Interest Periods expire. Each prepayment of Loans under this Section 2.7(b) shall be
made by the payment of the principal amount to be prepaid and, in the case of any Swing Loans or
Eurocurrency Loans, accrued interest thereon to the date of prepayment together with any amounts
due the Lenders under Section 8.1 hereof. Each prefunding of L/C Obligations shall be made in
accordance with Section 7.4 hereof. The Administrative Agent will promptly advise each Lender of
any notice of prepayment it receives from the Borrower.

Section 2.8. Place and Application of Payments. All payments of principal of and interest on
the Loans and the Reimbursement Obligations, and of all other Obligations payable by the Borrower
under this Agreement and the other Loan Documents, shall be made by the Borrower to the
Administrative Agent by no later than 12:00 Noon (Cincinnati time) on the due date thereof at the
office of the Administrative Agent in Cincinnati, Ohio (or such other location as the
Administrative Agent may designate to the Borrower) or, if such payment is to be made in an
Alternative Currency, no later than 12:00 noon local time at the place of payment at such account
with such financial institution as the Administrative Agent has previously specified in a notice to
the Borrower for the benefit of the Lender or Lenders entitled thereto. Any payments received
after such time shall be deemed to have been received by the Administrative Agent on the next
Business Day. All such payments shall be made (i) in U.S. Dollars, in immediately available funds
at the place of payment, or (ii) in the case of amounts payable hereunder in an Alternative
Currency, in such Alternative Currency in such funds then customary for the settlement of
international transactions in such currency, in each case without set-off or counterclaim. The
Administrative Agent will promptly thereafter cause to be distributed like funds relating to the
payment of principal or interest on Loans and on Reimbursement Obligations in which the Lenders
have purchased Participating Interests ratably to the Lenders and like funds relating to the
payment of any other amount payable to any Lender to such Lender, in each case to be applied in
accordance with the terms of this Agreement. If the Administrative Agent causes amounts to be
distributed to the Lenders in reliance upon the assumption that the Borrower will make a scheduled
payment and such scheduled payment is not so made, each Lender shall, on demand, repay to the
Administrative Agent the amount distributed to such Lender together with interest thereon in
respect of each day during the period commencing on the date such amount was distributed to such
Lender and ending on (but excluding) the date such Lender repays such amount to the Administrative
Agent, at a rate per annum equal to: (i) from the date the distribution was made to the date 2
Business Days after payment by such Lender is due hereunder, (x) if such scheduled payment was to
be made in U.S. Dollars, the Federal Funds Rate for each such day and (y) if such scheduled payment
was to be made in an Alternative Currency, the rate established by Section 2.3(c)(iii)(C) hereof
for Eurocurrency Loans denominated in such currency and (ii) from the date 2 Business Days after
the date such payment is due from such Lender to the date such payment is made by such Lender, (x)
if such scheduled payment was to be made in U.S. Dollars, the Base Rate in effect for each such day
and (y) if such scheduled payment was to be made in an Alternative Currency, the rate per annum
established by Section 2.3(c)(iii) hereof for Eurocurrency Loans denominated in such currency.

Anything contained herein to the contrary notwithstanding, (x) pursuant to the exercise of
remedies under Sections 7.2 and 7.3 hereof or (y) after written instruction by the Required Lenders
after the occurrence and during the continuation of an Event of Default, all payments and
collections received in respect of the Obligations and all proceeds received in respect of the
collateral pledged pursuant to the Pledge Agreements received, in each instance, by the
Administrative Agent or any of the Lenders shall be remitted to the Administrative Agent and
distributed as follows:

(a) first, to the payment of any outstanding costs and expenses incurred by the
Administrative Agent, and any security trustee therefor, in monitoring, verifying,
protecting, preserving or enforcing the Liens granted under the Pledge Agreements, in
protecting, preserving or enforcing rights under the Loan Documents, and in any event all
costs and expenses of a character which the Borrower has agreed to pay the Administrative
Agent under Section 10.13 hereof (such funds to be retained by the Administrative Agent for
its own account unless it has previously been reimbursed for such costs and expenses by the
Lenders, in which event such amounts shall be remitted to the Lenders to reimburse them for
payments theretofore made to the Administrative Agent);

(b) second, to the payment of principal and interest on the Swing Notes until paid in
full;

(c) third, to the payment of any outstanding interest and fees due under the Loan
Documents to be allocated pro rata in accordance with the aggregate unpaid amounts owing to
each holder thereof;

(d) fourth, to the payment of principal on the Notes, unpaid Reimbursement Obligations,
together with amounts to be held by the Administrative Agent as collateral security for any
outstanding L/C Obligations pursuant to Section 7.4 hereof (until the Administrative Agent
is holding an amount of cash equal to the then outstanding amount of all such L/C
Obligations), and Hedging Liability, the aggregate amount paid to, or held as collateral
security for, the Lenders and, in the case of Hedging Liability, their Affiliates to be
allocated pro rata in accordance with the aggregate unpaid amounts owing to each holder
thereof;

(e) fifth, to the payment of all other unpaid Obligations and all other indebtedness,
obligations, and liabilities of the Borrower and its Subsidiaries secured by the Pledge
Agreements (including, without limitation, Funds Transfer and Deposit Account Liability) to
be allocated pro rata in accordance with the aggregate unpaid amounts owing to each holder
thereof; and

(f) sixth, to the Borrower or whoever else may be lawfully entitled thereto.

Section 2.9. Commitment Terminations. The Borrower shall have the right at any time and from
time to time, upon 5 Business Days prior written notice to the Administrative Agent (or such
shorter period of time agreed to by the Administrative Agent), to terminate the Commitments in
whole or in part, any partial termination to be (i) in an amount equal to U.S. $1,000,000 or such
greater amount that is an integral multiple of U.S. $100,000 and (ii) allocated ratably among the
Lenders in proportion to their respective Percentages, provided that the Commitments may not be
reduced to an amount less than the sum of the aggregate principal amount of Swing Loans and L/C
Obligations and the Original Dollar Amount of Revolving Loans then outstanding. Any termination of
the Commitments below the L/C Sublimit then in effect shall reduce the L/C Sublimit by a like
amount. Any termination of the Commitments below the Swing Line Sublimit then in effect shall
reduce the Swing Line Sublimit by a like amount. The Administrative Agent shall give prompt notice
to each Lender of any such termination of the Commitments. Any termination of the Commitments
pursuant to this Section 2.9 may not be reinstated.

Section 2.10. Swing Loans. (a) Generally. Subject to the terms and conditions hereof, as
part of the Revolving Credit, the Administrative Agent agrees to make loans in U.S. Dollars to the
Borrower under the Swing Line (individually a “Swing Loan” and collectively the “Swing Loans”)
which shall not in the aggregate at any time outstanding exceed the Swing Line Sublimit; provided,
however, the sum of the (i) aggregate Original Dollar Amount of Revolving Loans, (ii) the aggregate
principal amount of Swing Loans and (iii) the aggregate principal amount of L/C Obligations at any
time outstanding shall not exceed the sum of all Commitments in effect at such time. The Swing
Loans may be availed of the Borrower from time to time and borrowings thereunder may be repaid and
used again during the period ending on the Termination Date; provided that each Swing Loan must be
repaid on the last day of the Interest Period applicable thereto. Each Swing Loan shall be in a
minimum amount of U.S. $250,000 or such greater amount that is an integral multiple of U.S.
$100,000.

(b) Interest on Swing Loans. Each Swing Loan shall bear interest until maturity (whether by
acceleration or otherwise) at a rate per annum, as selected by the Borrower in accordance with
subpart (c) below, equal to (i) the sum of the Base Rate plus the Applicable Margin for Base Rate
Loans from time to time in effect (computed on the basis of a year of 360 days and the actual
number of days elapsed) or (ii) the Administrative Agent’s Quoted Rate (computed on the basis of a
year of 360 days for the actual number of days elapsed). Interest on each Swing Loan shall be due
and payable under the Swing Note prior to such maturity on the last day of each Interest Period
applicable thereto.

(c) Requests for Swing Loans. The Borrower shall give the Administrative Agent prior notice
(which may be written or oral) no later than 12:00 Noon (Cincinnati time) on the date upon which
the Borrower requests that any Swing Loan be made, of the amount and date of such Swing Loan, and
the Interest Period requested therefor. Within 30 minutes after receiving such notice, the
Administrative Agent shall in its discretion quote an interest rate to the Borrower at which the
Administrative Agent would be willing to make such Swing Loan available to the Borrower for the
Interest Period so requested (the rate so quoted for a given Interest Period being herein referred
to as “Administrative Agent’s Quoted Rate”). The Borrower acknowledges and agrees that the
interest rate quote is given for immediate and irrevocable acceptance. If the Borrower does not so
immediately accept the Administrative Agent’s Quoted Rate for the full amount requested by the
Borrower for such Swing Loan, the Administrative Agent’s Quoted Rate shall be deemed immediately
withdrawn and such Swing Loan shall bear interest at the rate per annum determined by adding the
Applicable Margin for Base Rate Loans to the Base Rate as from time to time in effect. Subject to
the terms and conditions hereof, the proceeds of such Swing Loan shall be made available to the
Borrower on the date so requested at the offices of the Administrative Agent in Cincinnati, Ohio.
Anything contained in the foregoing to the contrary notwithstanding (i) the obligation of the
Administrative Agent to make Swing Loans shall be subject to all of the terms and conditions of
this Agreement and (ii) the Administrative Agent shall not be obligated to make more than one Swing
Loan during any one day.

(d) Refunding of Swing Loans. In its sole and absolute discretion, the Administrative Agent
may at any time, on behalf of the Borrower (which hereby irrevocably authorizes the Administrative
Agent to act on its behalf for such purpose) and with notice to the Borrower, request each Lender
to make a Revolving Loan in the form of a Base Rate Loan in an amount equal to such Lender’s
Percentage of the amount of the Swing Loans outstanding on the date such notice is given. Unless
an Event of Default described in Section 7.1(j) or 7.1(k) exists with respect to the Borrower,
regardless of the existence of any other Event of Default, each Lender shall make the proceeds of
its requested Revolving Loan available to the Administrative Agent, in immediately available funds,
at the Administrative Agent’s principal office in Cincinnati, Ohio, before 12:00 Noon (Cincinnati
time) on the Business Day following the day such notice is given. The proceeds of such Borrowing
of Revolving Loans shall be immediately applied to repay the outstanding Swing Loans.

(e) Participations. If any Lender refuses or otherwise fails to make a Revolving Loan when
requested by the Administrative Agent pursuant to Section 2.10(d) above (because an Event of
Default described in Section 7.1(j) or 7.1(k) exists with respect to the Borrower or otherwise),
such Lender will, by the time and in the manner such Revolving Loan was to have been funded to the
Administrative Agent, purchase from the Administrative Agent an undivided participating interest in
the outstanding Swing Loans in an amount equal to its Percentage of the aggregate principal amount
of Swing Loans that were to have been repaid with such Revolving Loans; provided that the foregoing
purchases shall be deemed made hereunder without any further action by such Lender or the
Administrative Agent. Each Lender that so purchases a participation in a Swing Loan shall
thereafter be entitled to receive its Percentage of each payment of principal received on the Swing
Loan and of interest received thereon accruing from the date such Lender funded to the
Administrative Agent its participation in such Loan. The several obligations of the Lenders under
this Section shall be absolute, irrevocable and unconditional under any and all circumstances
whatsoever and shall not be subject to any set-off, counterclaim or defense to payment that any
Lender may have or have had against the Borrower, any other Lender or any other Person whatever.
Without limiting the generality of the foregoing, such obligations shall not be affected by any
Default or Event of Default or by any reduction or termination of the Commitments of any Lender,
and each payment made by a Lender under this Section shall be made without any offset, abatement,
withholding or reduction whatsoever.

Section 2.11. The Notes. (a) The Revolving Loans made to the Borrower by a Lender shall be
evidenced by a single promissory note of that Borrower issued to such Lender in the form of Exhibit
D-1 hereto. Each such promissory note is hereinafter referred to as a “Revolving Note” and
collectively such promissory notes are referred to as the “Revolving Notes.”

(b) The Swing Loans made to the Borrower by the Administrative Agent shall be evidenced by a
single promissory note of the Borrower issued to the Administrative Agent in the form of Exhibit
D-2 hereto. Such promissory note is hereinafter referred to as a “Swing Note”.

(c) Unpaid Reimbursement Obligations owing from the Borrower to the L/C Issuer shall be
evidenced by a single promissory note of the Borrower issued to the L/C Issuer in the form of
Exhibit D-3 hereto. Such promissory note is hereinafter referred to as a “Letter of Credit Note”.

(d) In respect of the Revolving Credit and Swing Line, each Lender shall record on its books
and records or on a schedule to its appropriate Note the amount and currency and type of each Loan
advanced, continued or converted by it, all payments of principal and interest and the principal
balance from time to time outstanding thereon, and, for any Eurocurrency Loan, the Interest Period
and the interest rate applicable thereto. The Lender’s record thereof, whether shown on its books
and records or on a schedule to the relevant Note, shall be prima facie evidence as to all such
matters; provided, however, that the failure of any Lender to record any of the foregoing or any
error in any such record shall not limit or otherwise affect the obligation of the Borrower to
repay all Loans made to it together with accrued interest thereon. At the request of any Lender
and upon such Lender tendering to the Borrower the appropriate Note to be replaced, the Borrower
shall furnish a new Note to such Lender to replace any outstanding Note, and at such time the first
notation appearing on a schedule on the reverse side of, or attached to, such new Note shall set
forth the aggregate unpaid principal amount of all Loans, if any, then outstanding thereon.

(e) In respect of unpaid Reimbursement Obligations owing from the Borrower to the L/C Issuer,
the L/C Issuer shall record on its books and records or on a schedule to its Letter of Credit Note
the amount of each unpaid Reimbursement Obligation and all outstanding interest and fees applicable
thereon. The L/C Issuer’s record thereof, whether shown on its books and records or on a schedule
to the Letter of Credit Note, shall be prima facie evidence as to all such matters; provided,
however, that the failure of the L/C Issuer to record any of the foregoing or any error in any such
record shall not limit or otherwise affect the obligation of the Borrower to pay all unpaid
Reimbursement Obligations together with accrued interest and fees thereon. At the request of the
L/C Issuer and upon the L/C Issuer tendering to the Borrower the appropriate Note to be replaced,
the Borrower shall furnish a new Letter of Credit Note to the L/C Issuer to replace the outstanding
Letter of Credit Note, and at such time the first notation appearing on a schedule on the reverse
side of, or attached to, such new Note shall set forth the aggregate unpaid Reimbursement
Obligations and interest and fees, if any, then outstanding thereon.

(f) The Borrower acknowledges that (i) the Notes are intended to evidence and acknowledge its
indebtedness under this Agreement and under each Application, (ii) all payments under this
Agreement or where applicable in connection with any Application (whether of principal, interest or
otherwise) will be taken to be payments under the Notes, (iii) for the avoidance of doubt, interest
paid on the Notes must be paid outside Australia, and (iv) any Notes are to be issued to and held
by the Lenders outside of Australia.

Section 2.12. Fees. (a) Commitment Fee. The Borrower shall pay to the Administrative Agent
for the ratable account of the Lenders according to their Percentages a commitment fee at the rate
per annum equal to the Applicable Margin (computed on the basis of a year of 360 days and the
actual number of days elapsed) on the average daily Unused Commitments. Such commitment fee shall
be payable quarterly in arrears on the last day of each March, June, September, and December in
each year (commencing on the first such date occurring after the date hereof) and on the
Termination Date, unless the Commitments are terminated in whole on an earlier date, in which event
the commitment fee for the period to the date of such termination in whole shall be paid on the
date of such termination.

(b) Letter of Credit Fees. On the date of issuance or extension, or increase in the amount,
of any Letter of Credit pursuant to Section 2.2 hereof, the Borrower shall pay to the L/C Issuer
for its own account a fronting fee equal to 0.125% of the face amount of (or of the increase in the
face amount of) such Letter of Credit. Quarterly in arrears, on the last day of each March, June,
September, and December, commencing on the first such date occurring after the date hereof, the
Borrower shall pay to the Administrative Agent, for the ratable benefit of the Lenders according to
their Percentages, a letter of credit fee at a rate per annum equal to the Applicable Margin
(computed on the basis of a year of 360 days and the actual number of days elapsed) in effect
during each day of such quarter applied to the daily average face amount of Letters of Credit
outstanding during such quarter; provided that, while any Event of Default exists or after
acceleration, such rate shall increase by 2% over the rate otherwise payable and such fee shall be
paid on demand of the Administrative Agent at the request or with the consent of the Required
Lenders; provided however, that prior to acceleration, any rate increase pursuant to the foregoing
proviso shall be made at the direction of the Administrative Agent, acting at the request or with
the consent of the Required Lenders. In addition, the Borrower shall pay to the L/C Issuer for its
own account the L/C Issuer’s standard drawing, negotiation, amendment, transfer and other
administrative fees for each Letter of Credit. Such standard fees referred to in the preceding
sentence may be established by the L/C Issuer from time to time.

Section 3. Conditions Precedent.

The obligation of each Lender to advance, continue or convert any Loan (other than the
conversion into a Base Rate Loan) or of the L/C Issuer to issue, extend the expiration date
(including by not giving notice of non-renewal) of or increase the amount of any Letter of Credit
under this Agreement, shall be subject to the following conditions precedent:

Section 3.1. All Credit Events. At the time of each Credit Event hereunder:

(a) each of the representations and warranties set forth herein and in the other Loan
Documents shall be and remain true and correct in all material respects as of said time,
except to the extent the same expressly relate to an earlier date with respect to which such
representations and warranties shall be true and correct as of such earlier date;

(b) no Default or Event of Default shall have occurred and be continuing or would occur
as a result of such Credit Event;

(c) in the case of any request for an extension of credit under the Revolving Credit,

Revolving Loans, Swing Loans and L/C Obligations under this Agreement shall not exceed the
aggregate Commitments;

(d) in the case of a Borrowing the Administrative Agent shall have received the notice
required by Section 2.4 hereof, in the case of the issuance of any Letter of Credit the L/C
Issuer shall have received a duly completed Application together with any fees called for by
Section 2.12 hereof, and, in the case of an extension or increase in the amount of a Letter
of Credit, a written request therefor in a form acceptable to the L/C Issuer together with
fees called for by Section 2.12 hereof; and

(e) such Credit Event shall not violate any order, judgment or decree of any court or
other authority or any provision of law or regulation applicable to the Administrative Agent
or any Lender (including, without limitation, Regulation U of the Board of Governors of the
Federal Reserve System) as then in effect.

Each request for a Borrowing hereunder and each request for the issuance of, increase in the
amount of, or extension of the expiration date of, a Letter of Credit shall be deemed to be a
representation and warranty by the Borrower on the date of such Credit Event as to the facts
specified in subsections (a) through (d), both inclusive, of this Section.

Section 4.1. Stock Pledge. (a) The Obligations, Hedging Liability, and Funds Transfer and
Deposit Account Liability shall be secured by valid, perfected, and enforceable Liens on all right,
title, and interest of the Borrower and each Subsidiary in all capital stock and other equity
interests held by such Person in each Material Foreign Subsidiary, whether now owned or hereafter

no such Lien shall be required if it could cause a material adverse effect on the Borrower’s or the

of the total outstanding Voting Stock of such Material Foreign Subsidiary.

(b) In the event that any equity investor in a Joint Venture that is not a Subsidiary grants a

notice of such Lien, the Borrower shall, promptly upon request of the Administrative Agent, cause
the Obligations, Hedging Liability and Funds Transfer and Deposit Account Liability to be secured
by a valid, perfected and enforceable Lien on all right, title and interest of the Borrower and
each Subsidiary in all capital stock and other equity interests held by such Person in such Joint
Venture; provided, however, notwithstanding the foregoing, no such Lien shall be required if it
could cause a material adverse effect on the Borrower’s or any Subsidiary’s income tax liability.

(c) The Borrower acknowledges and agrees that the Liens on the capital stock and other equity
interests required under this Section 4.1 shall be granted to the Administrative Agent for the
benefit of the holders of the Obligations, the Hedging Liability, and the Funds Transfer and
Deposit Account Liability and shall be valid and perfected first priority Liens (except for
Permitted Liens) subject, however, to the provisos appearing at the end of Sections 4.1(a) and
4.1(b).

Section 4.2. Guaranties. The payment and performance of the Obligations, Hedging Liability,
and Funds Transfer and Deposit Account Liability shall at all times be guaranteed by each Material
Subsidiary pursuant to one or more guaranty agreements in form and substance reasonably acceptable
to the Administrative Agent (as the same may be amended, modified or supplemented from time to
time, individually a “Guaranty” and collectively the “Guaranties”).

Section 4.3. Further Assurances. The Borrower agrees that it shall, and shall cause each of
its Subsidiaries to, from time to time at the request of the Administrative Agent or the Required
Lenders, execute and deliver such documents and do such acts and things as the Administrative Agent

Section 5. Representations and Warranties.

The Borrower represents and warrants to each Lender and the Administrative Agent, and agrees,
that:

Section 5.1. Organization and Qualification. The Borrower and each of its Subsidiaries (i) is
duly organized, validly existing and in good standing under the laws of the jurisdiction of its
organization, (ii) has the power and authority to own its property and to transact the business in
which it is engaged and proposes to engage and (iii) is duly qualified and in good standing in each
jurisdiction where the ownership, leasing or operation of property or the conduct of its business
requires such qualification, except where the failure to be so qualified and in good standing could
not reasonably be expected to have a Material Adverse Effect.

Section 5.2. Authority and Enforceability. The Borrower has full right and authority to enter
into this Agreement and the other Loan Documents executed by it, to make the borrowings herein
provided for, to issue its Notes in evidence thereof, and to perform all of its obligations
hereunder and under the other Loan Documents executed by it. Each Material Subsidiary has full
right and authority to enter into the Loan Documents executed by it, to guarantee the Obligations,
Hedging Liability, and Funds Transfer and Deposit Account Liability and to perform all of its
obligations under the Loan Documents executed by it and grant the Liens, if any, described in the
Pledge Agreements. The Loan Documents delivered by the Borrower and by each Material Subsidiary
have been duly authorized, executed, and delivered by such Person and constitute valid and binding
obligations of such Person enforceable against it in accordance with their terms, except as
enforceability may be limited by bankruptcy, insolvency, fraudulent conveyance or similar laws
affecting creditors’ rights generally and general principles of equity (regardless of whether the
application of such principles is considered in a proceeding in equity or at law); and this
Agreement and the other Loan Documents do not, nor does the performance or observance by the
Borrower or any Subsidiary of any of the matters and things herein or therein provided for, (a)
contravene or constitute a default under any provision of law or any judgment, injunction, order or
decree binding upon the Borrower or any Subsidiary or any provision of the organizational documents
(e.g., charter, articles of incorporation or by-laws, articles of association or operating
agreement, partnership agreement or other similar document) of the Borrower or any Subsidiary, (b)
contravene or constitute a default under any covenant, indenture or agreement of or affecting the
Borrower or any Subsidiary or any of its Property, in each case where such contravention or
default, individually or in the aggregate, could reasonably be expected to have a Material Adverse
Effect or (c) result in the creation or imposition of any Lien on any Property of the Borrower or
any Subsidiary other than the Liens granted in favor of the Administrative Agent pursuant to the
Pledge Agreements or any other Liens created by or pursuant to this Agreement.

Section 5.3. Financial Reports. The audited consolidated financial statements of the Borrower
and its Subsidiaries as at December 31, 2003, and the unaudited interim consolidated financial
statements of the Borrower and its Subsidiaries as at September 30, 2004, for the 9 months then
ended, heretofore furnished to the Administrative Agent, fairly and adequately present, in all
material respects, the consolidated financial condition of the Borrower and its Subsidiaries as at
said dates and the consolidated results of their operations and cash flows for the periods then
ended in conformity with GAAP applied on a consistent basis. Neither the Borrower nor any
Subsidiary has contingent liabilities or judgments, orders or injunctions against it that are
material to it other than as indicated on such financial statements or, with respect to future
periods, on the financial statements furnished pursuant to Section 6.1 hereof.

Section 5.4. No Material Adverse Change. Since September 30, 2004, there has been no change
in the condition (financial or otherwise) the Borrower and its Subsidiaries except those occurring
in the ordinary course of business, none of which individually or in the aggregate could reasonably
be expected to have a Material Adverse Effect.

Section 5.5. Litigation and other Controversies. Except as set forth on Schedule 5.5, there
is no litigation, arbitration or governmental proceeding pending or, to the knowledge of the
Borrower and its Subsidiaries, threatened against the Borrower or any of its Subsidiaries that
could reasonably be expected to have a Material Adverse Effect.

Section 5.6. True and Complete Disclosure. All information furnished by or on behalf of the
Borrower or any of its Subsidiaries in writing to the Administrative Agent or any Lender for
purposes of or in connection with this Agreement, or any transaction contemplated herein, is true
and accurate in all material respects and not incomplete by omitting to state any fact necessary to
make such information (taken as a whole) not misleading in light of the circumstances under which
such information was provided; provided that to the extent any such information was based upon or
constitutes a forecast or projection, the Borrower represents only that it acted in good faith and
utilized assumptions reasonable at the time made and due care in the preparation of such
information, report, financial statement, exhibit or schedule.

Section 5.7. Use of Proceeds; Margin Stock. (a) All proceeds of Loans shall be used by the
Borrower to refinance certain existing indebtedness and for working capital purposes and other
general corporate purposes (including the funding of Permitted Acquisitions) of the Borrower and
its Subsidiaries. No part of the proceeds of any Loan or other extension of credit hereunder will
be used by the Borrower or any Subsidiary thereof to purchase or carry any margin stock (within the
meaning of Regulation U of the Board of Governors of the Federal Reserve System) or to extend
credit to others for the purpose of purchasing or carrying any margin stock. Neither the making of
any Loan or other extension of credit hereunder nor the use of the proceeds thereof will violate or
be inconsistent with the provisions of Regulations T, U or X of the Board of Governors of the
Federal Reserve System and any successor to all or any portion of such regulations. Margin Stock
(as defined above) constitutes less than 25% of the value of those assets of the Borrower and its
Subsidiaries that are subject to any limitation on sale, pledge or other restriction hereunder.

Section 5.8. Taxes. All material tax returns required to be filed by the Borrower or any
Subsidiary in any jurisdiction have, in fact, been filed, and all material taxes, assessments,
fees, and other governmental charges upon the Borrower or any Subsidiary or upon any of their
Property, income or franchises, which are shown to be due and payable in such returns, have been
paid except to the extent that the Borrower or any Subsidiary is contesting the same in good faith.
The Borrower does not know of any proposed additional material tax assessment against it or its
Subsidiaries for which adequate provisions in accordance with GAAP have not been made on their
accounts. Adequate provisions in accordance with GAAP for taxes on the books of the Borrower and
its Subsidiaries have been made for all open years, and for the current fiscal period.

Section 5.9. ERISA. The Borrower and each other member of its Controlled Group has fulfilled
its obligations under the minimum funding standards of, and is in compliance in all material
respects with, ERISA and the Code to the extent applicable to it and, other than a liability for
premiums under Section 4007 of ERISA, does not owe any liability to the PBGC or a Plan under Title
IV of ERISA. Except with respect to the Welfare Plans identified on Schedule 5.9, as of the date
hereof, neither the Borrower nor any Subsidiary has any contingent liabilities with respect to any
post-retirement benefits under a Welfare Plan, other than liability for continuation coverage
described in article 6 of Title I of ERISA.

Section 5.10. Subsidiaries. Schedule 5.10 correctly sets forth, as of the Closing Date, each

ownership (direct and indirect) of the Borrower in each class of capital stock or other equity
interests of each of its Subsidiaries and also identifies the direct owner thereof.

Section 5.11. Compliance with Laws. The Borrower and each of its Subsidiaries is in
compliance with all applicable statutes, regulations and orders of, and all applicable restrictions
imposed by, all governmental authority, or any subdivision thereof, in respect of the conduct of
their businesses and the ownership of their property, except such noncompliances as could not
reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect.

Section 5.12. Environmental Matters. The Borrower and each of its Subsidiaries is in
compliance with all applicable Environmental Laws and the requirements of any permits issued under
such Environmental Laws, except to the extent that the aggregate effect of all noncompliances could
not reasonably be expected to have a Material Adverse Effect. Except as disclosed in the
Borrower’s most recent Form 10-K or Form 10-Q filed with the SEC, there are no pending or, to the
best knowledge of the Borrower and its Subsidiaries after due inquiry, threatened Environmental
Claims, including any such claims (regardless of materiality) for liabilities under CERCLA relating
to the disposal of Hazardous Materials, against the Borrower or any of its Subsidiaries or any real
property, including leaseholds, owned or operated by the Borrower or any of its Subsidiaries.
There are no facts, circumstances, conditions or occurrences on any real property, including
leaseholds, owned or operated by the Borrower or any of its Subsidiaries that, to the best
knowledge of the Borrower and its Subsidiaries after due inquiry, could reasonably be expected (i)
to form the basis of an Environmental Claim against the Borrower or any of its Subsidiaries or any
such real property, or (ii) to cause any such real property to be subject to any restrictions on
the ownership, occupancy, use or transferability of such real property by the Borrower or any of
its Subsidiaries under any applicable Environmental Law. Hazardous Materials have not been
Released on or from any real property, including leaseholds, owned or operated by the Borrower or
any of its Subsidiaries where the costs of remediating such Release may reasonably be expected to
have a Material Adverse Effect.

any Subsidiary is an “investment company” or a company “controlled” by an “investment company”
within the meaning of the Investment Company Act of 1940, as amended, or a “public utility holding
company” within the meaning of the Public Utility Holding Company Act of 1935, as amended.

Section 5.14. Intellectual Property. The Borrower and each of its Subsidiaries owns all the
patents, trademarks, permits, service marks, trade names, copyrights, franchises and formulas, or
rights with respect to the foregoing, or each has obtained licenses of all other rights of whatever
nature necessary for the present conduct of its businesses, in each case without any known conflict
with the rights of others which, or the failure to obtain which, as the case may be, could
reasonably be expected to result in a Material Adverse Effect.

Section 5.15. Good Title. The Borrower and its Subsidiaries have good and marketable title,
or valid leasehold interests, to their assets as reflected on the Borrower’s most recent
consolidated balance sheet provided to the Administrative Agent, except for sales of assets in the
ordinary course of business, subject to no Liens, other than Permitted Liens.

Section 5.16. Labor Relations. Neither the Borrower nor any of its Subsidiaries is engaged in
any unfair labor practice that could reasonably be expected to have a Material Adverse Effect.
There is no strike, labor dispute, slowdown or stoppage pending against the Borrower or any of its
Subsidiaries or, to the best knowledge of the Borrower and its Subsidiaries, threatened against the
Borrower or any of its Subsidiaries, except such as could not reasonably be expected to have a
Material Adverse Effect.

Section 5.17. Capitalization. Except as disclosed on Schedule 5.17, as of the Closing Date,
all outstanding equity interests of the Borrower and each Subsidiary have been duly authorized and
validly issued, and are fully paid and nonassessable, and there are no outstanding commitments or
other obligations of the Borrower or any Subsidiary to issue, and no rights of any Person to
acquire, any equity interests in the Borrower or any Subsidiary.

Section 5.18. Other Agreements. Neither the Borrower nor any Subsidiary is in default under
the terms of any covenant, indenture or agreement of or affecting the Borrower, any Subsidiary or
any of their Property, which default if uncured could reasonably be expected to have a Material
Adverse Effect.

Section 5.19. Governmental Authority and Licensing. The Borrower and its Subsidiaries have
received all licenses, permits, and approvals of all federal, state, local, and foreign
governmental authorities, if any, necessary to conduct their businesses, in each case where the
failure to obtain or maintain the same could reasonably be expected to have a Material Adverse
Effect. No investigation or proceeding with respect to any such licenses, permits and approvals
that, if adversely determined, could reasonably be expected to result in a Material Adverse Effect
is pending or, to the knowledge of the Borrower and its Subsidiaries, threatened.

Section 5.20. Approvals. No authorization, consent, license or exemption from, or filing or
registration with, any court or governmental department, agency or instrumentality, nor any
approval or consent of any other Person, is or will be necessary to the valid execution, delivery
or performance by the Borrower or any Subsidiary of any Loan Document, except for such approvals
which have been obtained prior to the date of this Agreement and remain in full force and effect.

Section 5.21. Affiliate Transactions. Neither the Borrower nor any Subsidiary is a party to
any contract or agreement with any of its Affiliates on terms and conditions which are less
favorable to the Borrower or such Subsidiary than would be usual and customary in similar contracts
or agreements between Persons not affiliated with each other.

Section 5.22. Solvency. The Borrower and its Subsidiaries are solvent, able to pay their
debts as they become due, and have sufficient capital to carry on their business and all businesses
in which they are about to engage.

respects, with the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001))
(the “Patriot Act”). No part of the proceeds of the Loans will be used, directly or indirectly,
for any payments to any governmental official or employee, political party, official of a political
party, candidate for political office, or anyone else acting in an official capacity, in order to
obtain, retain or direct business or obtain any improper advantage, in violation of the United
States Foreign Corrupt Practices Act of 1977, as Amended.

fund or maintain any Eurocurrency Loan or Swing Loan or the relending or reinvesting of such
deposits or amounts paid or prepaid to such Lender or by reason of breakage of interest rate swap
agreements or the liquidation of other hedging contracts or agreements) as a result of:

(a) any payment, prepayment or conversion of a Eurocurrency Loan or Swing Loan on a
date other than the last day of its Interest Period,

(b) any failure (because of a failure to meet the conditions of Section 3 or otherwise)
by the Borrower to borrow or continue a Eurocurrency Loan or Swing Loan, or to convert a
Base Rate Loan into a Eurocurrency Loan or Swing Loan, on the date specified in a notice
given pursuant to Section 2.4(a) hereof,

(c) any failure by the Borrower to make any payment of principal on any Eurocurrency
Loan or Swing Loan when due (whether by acceleration or otherwise), or

(d) any acceleration of the maturity of a Eurocurrency Loan or Swing Loan as a result
of the occurrence of any Event of Default hereunder,

then, upon the demand of such Lender, the Borrower shall pay to such Lender such amount as will
reimburse such Lender for such loss, cost or expense. If any Lender makes such a claim for
compensation, it shall provide to the Borrower, with a copy to the Administrative Agent, a
certificate setting forth the amount of such loss, cost or expense in reasonable detail (including
an explanation of the basis for and the computation of such loss, cost or expense) and the amounts
shown on such certificate shall be conclusive absent manifest error.

Section 8.2. Illegality. Notwithstanding any other provisions of this Agreement or any Note,
if at any time any change in applicable law, rule or regulation or in the interpretation thereof
made after the Closing Date makes it unlawful for any Lender to make or continue to maintain any
Eurocurrency Loans or to perform its obligations as contemplated hereby, such Lender shall promptly
give notice thereof to the Borrower and the Administrative Agent and such Lender’s obligations to
make or maintain Eurocurrency Loans under this Agreement shall be suspended until it is no longer
unlawful for such Lender to make or maintain Eurocurrency Loans. The Borrower shall prepay on
demand the outstanding principal amount of any such affected Eurocurrency Loans, together with all
interest accrued thereon and all other amounts then due and payable to such Lender under this
Agreement; provided, however, subject to all of the terms and conditions of this Agreement, the
Borrower may then elect to borrow the principal amount of the affected Eurocurrency Loans from such
Lender by means of Base Rate Loans from such Lender, which Base Rate Loans shall not be made
ratably by the Lenders but only from such affected Lender.

Section 8.3. Unavailability of Deposits or Inability to Ascertain, or Inadequacy of, LIBOR.
If on or prior to the first day of any Interest Period for any Borrowing of Eurocurrency Loans:

(a) the Administrative Agent determines that deposits in U.S. Dollars or the applicable
Alternative Currency (in the applicable amounts) are not being offered to it in the
interbank eurocurrency market for such Interest Period, or that by reason of circumstances
affecting the interbank eurocurrency market adequate and reasonable means do not exist for
ascertaining the applicable LIBOR, or

(b) the Required Lenders advise the Administrative Agent that (i) LIBOR as determined
by the Administrative Agent will not adequately and fairly reflect the cost to such Lenders
of funding their Eurocurrency Loans for such Interest Period or (ii) that the making or
funding of Eurocurrency Loans become impracticable,

then the Administrative Agent shall forthwith give notice thereof to the Borrower and the Lenders,
whereupon until the Administrative Agent notifies the Borrower that the circumstances giving rise
to such suspension no longer exist, the obligations of the Lenders to make Eurocurrency Loans shall
be suspended.

Section 8.4. Yield Protection. (a) If, on or after the date hereof, the adoption of any
applicable law, rule or regulation, or any change therein, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable agency charged
with the interpretation or administration thereof, or compliance by any Lender (or its Lending
Office) with any request or directive (whether or not having the force of law) of any such
authority, central bank or comparable agency:

(i) shall subject any Lender (or its Lending Office) to any tax, duty or other charge
with respect to its Eurocurrency Loans, its Notes, its Letter(s) of Credit, or its
participation in any thereof, any Reimbursement Obligations owed to it or its obligation to
make Eurocurrency Loans, issue a Letter of Credit, or to participate therein, or shall
change the basis of taxation of payments to any Lender (or its Lending Office) of the
principal of or interest on its Eurocurrency Loans, Letter(s) of Credit, or participations
therein or any other amounts due under this Agreement or any other Loan Document in respect
of its Eurocurrency Loans, Letter(s) of Credit, any participation therein, any Reimbursement
Obligations owed to it, or its obligation to make Eurocurrency Loans, or issue a Letter of
Credit, or acquire participations therein (except for changes in the rate of tax on the
overall net income of such Lender or its Lending Office imposed by the jurisdiction in which
such Lender’s principal executive office or Lending Office is located); or

(ii) shall impose, modify or deem applicable any reserve, special deposit or similar
requirement (including, without limitation, any such requirement imposed by the Board of
Governors of the Federal Reserve System, but excluding with respect to any Eurocurrency
Loans any such requirement included in an applicable Reserve Percentage) against assets of,
deposits with or for the account of, or credit extended by, any Lender (or its Lending
Office) or shall impose on any Lender (or its Lending Office) or on the interbank market any
other condition affecting its Eurocurrency Loans, its Notes, its Letter(s) of Credit, or its
participation in any thereof, any Reimbursement Obligation owed to it, or its obligation to
make Eurocurrency Loans, or to issue a Letter of Credit, or to participate therein;

and the result of any of the foregoing is to increase the cost to such Lender (or its Lending
Office) of making or maintaining any Eurocurrency Loan, issuing or maintaining a Letter of Credit,
or participating therein, or to reduce the amount of any sum received or receivable by such Lender
(or its Lending Office) under this Agreement or under any other Loan Document with respect thereto,
by an amount deemed by such Lender to be material, then, within 15 days after demand by such Lender
(with a copy to the Administrative Agent), the Borrower shall be obligated to pay to such Lender
such additional amount or amounts as will compensate such Lender for such increased cost or
reduction.

(b) If, after the date hereof, any Lender or the Administrative Agent shall have determined
that the adoption of any applicable law, rule or regulation regarding capital adequacy, or any
change therein, or any change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or administration
thereof, or compliance by any Lender (or its Lending Office) or any corporation controlling such
Lender 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 had the effect of reducing the
rate of return on such Lender’s or such corporation’s capital as a consequence of its obligations
hereunder to a level below that which such Lender or such corporation could have achieved but for
such adoption, change or compliance (taking into consideration such Lender’s or such corporation’s
policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then
from time to time, within 15 days after demand by such Lender (with a copy to the Administrative
Agent), the Borrower shall pay to such Lender such additional amount or amounts as will compensate
such Lender for such reduction.

(c) A certificate of a Lender claiming compensation under this Section 8.4 and setting forth
the additional amount or amounts to be paid to it hereunder shall be conclusive absent manifest
error. In determining such amount, such Lender may use any reasonable averaging and attribution
methods.

Section 8.5. Substitution of Lenders. Upon the receipt by the Borrower of (a) a claim from
any Lender for compensation under Section 8.4 or 10.1 hereof, (b) notice by any Lender to the
Borrower of any illegality pursuant to Section 8.2 hereof or (c) in the event any Lender is in
default in any material respect with respect to its obligations under the Loan Documents (any such
Lender referred to in clause (a), (b) or (c) above being hereinafter referred to as an “Affected
Lender”), the Borrower may, in addition to any other rights the Borrower may have hereunder or
under applicable law, require, at its expense, any such Affected Lender to assign, at par plus
accrued interest and fees, without recourse, all of its interest, rights, and obligations hereunder
(including all of its Commitments and the Loans and participation interests in Letters of Credit
and other amounts at any time owing to it hereunder and the other Loan Documents) to a bank or
other institutional lender specified by the Borrower, provided that (i) such assignment shall not
conflict with or violate any law, rule or regulation or order of any court or other governmental
authority, (ii) if the assignment is to a Person other than a Lender, the Borrower shall have
received the written consent of the Administrative Agent and the L/C Issuer, which consents shall
not be unreasonably withheld or delayed, to such assignment, (iii) the Borrower shall have paid to
the Affected Lender all monies (together with amounts due such Affected Lender under Section 8.1
hereof as if the Loans owing to it were prepaid rather than assigned) other than principal owing to
it hereunder, and (iv) the assignment is entered into in accordance with the other requirements of
Section 10.10 hereof.

Section 8.6. Lending Offices. Each Lender may, at its option, elect to make its Loans
hereunder at the branch, office or affiliate specified on the appropriate signature page hereof
(each a “Lending Office”) for each type of Loan available hereunder or at such other of its
branches, offices or affiliates as it may from time to time elect and designate in a written notice
to the Borrower and the Administrative Agent. To the extent reasonably possible, a Lender shall
designate an alternative branch or funding office with respect to its Eurocurrency Loans to reduce
any liability of the Borrower to such Lender under Section 8.4 hereof or to avoid the
unavailability of Eurocurrency Loans under Section 8.3 hereof, so long as such designation is not
disadvantageous to the Lender.

Section 8.7. Discretion of Lender as to Manner of Funding. Notwithstanding any other
provision of this Agreement, each Lender shall be entitled to fund and maintain its funding of all
or any part of its Loans in any manner it sees fit, it being understood, however, that for the
purposes of this Agreement all determinations hereunder with respect to Eurocurrency Loans shall be
made as if each Lender had actually funded and maintained each Eurocurrency Loan through the
purchase of deposits in the interbank eurocurrency market having a maturity corresponding to such
Loan’s Interest Period, and bearing an interest rate equal to LIBOR for such Interest Period.

Section 9. The Administrative Agent.

Section 9.1. Appointment and Authorization of Administrative Agent. Each Lender hereby
appoints Fifth Third Bank, an Ohio banking corporation as the Administrative Agent under the Loan
Documents and hereby authorizes the Administrative Agent to take such action as Administrative
Agent on its behalf and to exercise such powers under the Loan Documents as are delegated to the
Administrative Agent by the terms thereof, together with such powers as are reasonably incidental
thereto. Notwithstanding the use of the word “Administrative Agent” as a defined term, the Lenders
expressly agree that the Administrative Agent is not acting as a fiduciary of any Lender in respect
of the Loan Documents, the Borrower or otherwise, and nothing herein or in any of the other Loan
Documents shall result in any duties or obligations on the Administrative Agent or any of the
Lenders except as expressly set forth herein.

Section 9.2. Administrative Agent and its Affiliates. The Administrative Agent shall have the
same rights and powers under this Agreement and the other Loan Documents as any other Lender and
may exercise or refrain from exercising such rights and power as though it were not the
Administrative Agent, and the Administrative Agent and its affiliates may accept deposits from,
lend money to, and generally engage in any kind of business with the Borrower or any Affiliate of
the Borrower as if it were not the Administrative Agent under the Loan Documents. The term
“Lender” as used herein and in all other Loan Documents, unless the context otherwise clearly
requires, includes the Administrative Agent in its individual capacity as a Lender. References in
Section 2 hereof to the Administrative Agent’s Loans, or to the amount owing to the Administrative
Agent for which an interest rate is being determined, refer to the Administrative Agent in its
individual capacity as a Lender.

Section 9.3. Action by Administrative Agent. If the Administrative Agent receives from the
Borrower a written notice of an Event of Default pursuant to Section 6.1 hereof, the Administrative
Agent shall promptly give each of the Lenders written notice thereof. Without limiting the
generality of the foregoing, the Administrative Agent shall not be required to take any action
hereunder with respect to any Default or Event of Default, except as expressly provided in the Loan
Documents. Upon the occurrence of an Event of Default, the Administrative Agent shall take such
action to enforce its Lien on the collateral granted pursuant to the Pledge Agreements and to
preserve and protect such collateral as may be directed by the Required Lenders. Unless and until
the Required Lenders give such direction, the Administrative Agent may (but shall not be obligated
to) take or refrain from taking such actions as it deems appropriate and in the best interest of
all the Lenders. In no event, however, shall the Administrative Agent be required to take any
action in violation of applicable law or of any provision of any Loan Document, and the
Administrative Agent shall in all cases be fully justified in failing or refusing to act hereunder
or under any other Loan Document unless it first receives any further assurances of its
indemnification from the Lenders that it may require, including prepayment of any related expenses
and any other protection it requires against any and all costs, expense, and liability which may be
incurred by it by reason of taking or continuing to take any such action. The Administrative Agent
shall be entitled to assume that no Default or Event of Default exists unless notified in writing
to the contrary by a Lender or the Borrower. In all cases in which the Loan Documents do not
require the Administrative Agent to take specific action, the Administrative Agent shall be fully
justified in using its discretion in failing to take or in taking any action thereunder. Any
instructions of the Required Lenders, or of any other group of Lenders called for under the
specific provisions of the Loan Documents, shall be binding upon all the Lenders and the holders of
the Obligations.

Section 9.4. Consultation with Experts. The Administrative Agent may consult with legal
counsel, independent public accountants, and other experts selected by it and shall not be liable
for any action taken or omitted to be taken by it in good faith in accordance with the advice of
such counsel, accountants or experts.

Section 9.5. Liability of Administrative Agent; Credit Decision. Neither the Administrative
Agent nor any of its directors, officers, agents or employees shall be liable for any action taken
or not taken by it in connection with the Loan Documents: (i) with the consent or at the request
of the Required Lenders or (ii) in the absence of its own gross negligence or willful misconduct.
Neither the Administrative Agent nor any of its directors, officers, agents or employees shall be
responsible for or have any duty to ascertain, inquire into or verify: (i) any statement, warranty
or representation made in connection with this Agreement, any other Loan Document or any Credit
Event; (ii) the performance or observance of any of the covenants or agreements of the Borrower or
any Subsidiary contained herein or in any other Loan Document; (iii) the satisfaction of any
condition specified in Section 3 hereof, except receipt of items required to be delivered to the
Administrative Agent; or (iv) the validity, effectiveness, genuineness, enforceability, perfection,
value, worth or collectibility hereof or of any other Loan Document or of any other documents or
writing furnished in connection with any Loan Document or of any collateral subject to the Liens
granted pursuant to the Pledge Agreements; and the Administrative Agent makes no representation of
any kind or character with respect to any such matter mentioned in this sentence. The
Administrative Agent may execute any of its duties under any of the Loan Documents by or through
employees, agents, and attorneys-in-fact and shall not be answerable to the Lenders, the Borrower,
or any other Person for the default or misconduct of any such agents or attorneys-in-fact selected
with reasonable care. The Administrative Agent shall not incur any liability by acting in reliance
upon any notice, consent, certificate, other document or statement (whether written or oral)
believed by it to be genuine or to be sent by the proper party or parties. In particular and
without limiting any of the foregoing, the Administrative Agent shall have no responsibility for
confirming the accuracy of any compliance certificate or other document or instrument received by
it under the Loan Documents. The Administrative Agent may treat the payee of any Note as the
holder thereof until written notice of transfer shall have been filed with the Administrative Agent
signed by such payee in form satisfactory to the Administrative Agent. Each Lender acknowledges
that it has independently and without reliance on the Administrative Agent or any other Lender, and
based upon such information, investigations and inquiries as it deems appropriate, made its own
credit analysis and decision to extend credit to the Borrower in the manner set forth in the Loan
Documents. It shall be the responsibility of each Lender to keep itself informed as to the
creditworthiness of the Borrower and its Subsidiaries, and the Administrative Agent shall have no
liability to any Lender with respect thereto.

Section 9.6. Indemnity. The Lenders shall ratably, in accordance with their respective
Percentages, indemnify and hold the Administrative Agent, and its directors, officers, employees,
agents, and representatives harmless from and against any liabilities, losses, costs or expenses
suffered or incurred by it under any Loan Document or in connection with the transactions
contemplated thereby, regardless of when asserted or arising, except to the extent they are
promptly reimbursed for the same by the Borrower and except to the extent that any event giving
rise to a claim was caused by the gross negligence or willful misconduct of the party seeking to be
indemnified. The obligations of the Lenders under this Section shall survive termination of this
Agreement. The Administrative Agent shall be entitled to offset amounts received for the account
of a Lender under this Agreement against unpaid amounts due from such Lender to the Administrative
Agent hereunder (whether as fundings of participations, indemnities or otherwise), but shall not be
entitled to offset against amounts owed to the Administrative Agent by any Lender arising outside
of this Agreement and the other Loan Documents.

Section 9.7. Resignation of Administrative Agent and Successor Administrative Agent. The
Administrative Agent may resign at any time by giving written notice thereof to the Lenders and the
Borrower. Upon any such resignation of the Administrative Agent, the Required Lenders, with the
consent of the Borrower (provided that during the existence of a Default or Event of Default, such
consent shall not be required), shall have the right to appoint a successor Administrative Agent.
If no successor Administrative Agent shall have been so appointed by the Required Lenders, and
shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s
giving of notice of resignation then the retiring Administrative Agent may, on behalf of the
Lenders, appoint a successor Administrative Agent, which may be any Lender hereunder or any
commercial bank organized under the laws of the United States of America or of any State thereof
and having a combined capital and surplus of at least U.S. $200,000,000. Upon the acceptance of
its appointment as the Administrative Agent hereunder, such successor Administrative Agent shall
thereupon succeed to and become vested with all the rights and duties of the retiring
Administrative Agent under the Loan Documents, and the retiring Administrative Agent shall be
discharged from its duties and obligations thereunder. After any retiring Administrative Agent’s
resignation hereunder as Administrative Agent, the provisions of this Section 9 and all protective
provisions of the other Loan Documents shall inure to its benefit as to any actions taken or
omitted to be taken by it while it was Administrative Agent, but no successor Administrative Agent
shall in any event be liable or responsible for any actions of its predecessor.

Section 9.8. L/C Issuer. The L/C Issuer shall act on behalf of the Lenders with respect to
any Letters of Credit issued by it and the documents associated therewith. The L/C Issuer shall
have all of the benefits and immunities (i) provided to the Administrative Agent in this Section 9
with respect to any acts taken or omissions suffered by the L/C Issuer in connection with Letters
of Credit issued by it or proposed to be issued by it and the Applications pertaining to such
Letters of Credit as fully as if the term “Administrative Agent”, as used in this Section 9,
included the L/C Issuer with respect to such acts or omissions and (ii) as additionally provided in
this Agreement with respect to such L/C Issuer.

Section 9.9. Hedging Liability and Funds Transfer and Deposit Account Liability Arrangements.
By virtue of a Lender’s execution of this Agreement or an assignment agreement pursuant to Section
10.10 hereof, as the case may be, any Affiliate of such Lender with whom the Borrower or any
Subsidiary has entered into an agreement creating Hedging Liability or Funds Transfer and Deposit
Account Liability shall be deemed a Lender party hereto for purposes of any reference in a Loan
Document to the parties for whom the Administrative Agent is acting, it being understood and agreed
that the rights and benefits of such Affiliate under the Loan Documents consist exclusively of such
Affiliate’s right to share in payments and collections out of the collateral subject to the Liens
granted pursuant to the Pledge Agreements and the Guaranties as more fully set forth in Section 2.8
and Section 4 hereof. In connection with any such distribution of payments and collections, the
Administrative Agent shall be entitled to assume no amounts are due to any Lender or its Affiliate
with respect to Hedging Liability or Funds Transfer and Deposit Account Liability unless such
Lender has notified the Administrative Agent in writing of the amount of any such liability owed to
it or its Affiliate prior to such distribution; provided, however, that the consent of any such
Affiliate shall not be required for any amendment or other modification to this Agreement or any
other Loan Document or for the release of any collateral or the release of the Borrower or any
party to any of the Guaranties.

Section 9.10. Designation of Additional Agents. Fleet National Bank, a Bank of America
company, is designated as Syndication Agent for this Agreement, and the Administrative Agent shall
have the continuing right, for purposes hereof, at any time and from time to time to designate one
or more of the Lenders (and/or its or their Affiliates) as “documentation agents,” “arrangers” or
other designations for purposes hereto, but no such designation, including the designation of Fleet
National Bank, a Bank of America company, as Syndication Agent, shall have any substantive effect,
and no such Lenders or their Affiliates shall have any additional powers, duties or
responsibilities as a result thereof.

Section 10. Miscellaneous.

Section 10.1. Withholding Taxes. (a) Payments Free of Withholding. Except as otherwise
required by law and subject to Section 10.1(b) hereof, each payment by the Borrower under this
Agreement or the other Loan Documents shall be made without withholding or deduction for or on
account of any present or future taxes, levies, imposts, deductions, charges or withholdings and
all liabilities with respect thereto (other than overall net income taxes on the recipient imposed
by the jurisdiction in which its principal executive office or Lending Office is located) imposed
by or within the jurisdiction in which the Borrower is domiciled, any jurisdiction from which the
Borrower or any other Person on behalf of the Borrower makes any payment, or (in each case) any
political subdivision or taxing authority thereof or therein. If any such withholding or deduction
is so required by law, the Borrower shall make the withholding or deduction, pay the amount
withheld to the appropriate governmental authority before penalties attach thereto or interest
accrues thereon and forthwith pay such additional amount as may be necessary to ensure that the net
amount actually received by each Lender and the Administrative Agent free and clear of such taxes
(including such taxes on such additional amount) is equal to the amount which that Lender or the
Administrative Agent (as the case may be) would have received had such withholding not been made.
If the Administrative Agent or any Lender pays any amount in respect of any such taxes, penalties
or interest, the Borrower with respect to whom such payments were made shall reimburse the
Administrative Agent or such Lender for that payment on demand in the currency in which such
payment was made. If the Borrower pays any such taxes, penalties or interest, it shall deliver
official tax receipts evidencing that payment or certified copies thereof to the Lender or
Administrative Agent on whose account such withholding was made (with a copy to the Administrative
Agent if not the recipient of the original) on or before the thirtieth day after payment.

(b) U.S. Withholding Tax Exemptions. Each Lender that is not a United States person (as such
term is defined in Section 7701(a)(30) of the Code) shall submit to the Borrower and the
Administrative Agent on or before the date the initial Credit Event is made hereunder or, if later,
the date such financial institution becomes a Lender hereunder, two duly completed and signed
copies of (i) either Form W-8 BEN (relating to such Lender and entitling it to a complete exemption
from withholding under the Code on all amounts to be received by such Lender, including fees,
pursuant to the Loan Documents and the Obligations) or Form W-8 ECI (relating to all amounts to be
received by such Lender, including fees, pursuant to the Loan Documents and the Obligations) of the
United States Internal Revenue Service or (ii) solely if such Lender is claiming exemption from
United States withholding tax under Section 871(h) or 881(c) of the Code with respect to payments
of “portfolio interest”, a Form W-8 BEN, or any successor form prescribed by the Internal Revenue
Service, and a certificate representing that such Lender is not a bank for purposes of Section
881(c) of the Code, is not a 10-percent shareholder (within the meaning of Section 871(h)(3)(B) of
the Code) of the Borrower and is not a controlled foreign corporation related to the Borrower
(within the meaning of Section 864(d)(4) of the Code). Thereafter and from time to time, each such
Lender shall submit to the Borrower and the Administrative Agent such additional duly completed and
signed copies of one or the other of such Forms (or such successor forms as shall be adopted from
time to time by the relevant United States taxing authorities) and such other certificates as may
be (i) requested by the Borrower in a written notice, directly or through the Administrative Agent,
to such Lender and (ii) required under then-current United States law or regulations to avoid or
reduce United States withholding taxes on payments in respect of all amounts to be received by such
Lender, including fees, pursuant to the Loan Documents or the Obligations. Upon the request of the
Borrower or the Administrative Agent, each Lender that is a United States person (as such term is
defined in Section 7701(a)(30) of the Code) shall submit to the Borrower and the Administrative
Agent a certificate to the effect that it is such a United States person.

(c) Inability of Lender to Submit Forms. If any Lender determines, as a result of any change
in applicable law, regulation or treaty, or in any official application or interpretation thereof
that occurs after the date it became a Lender hereunder, that it is unable to submit to the
Borrower or the Administrative Agent any form or certificate that such Lender is obligated to
submit pursuant to subsection (b) of this Section 10.1 or that such Lender is required to withdraw
or cancel any such form or certificate previously submitted or any such form or certificate
otherwise becomes ineffective or inaccurate, such Lender shall promptly notify the Borrower and
Administrative Agent of such fact and the Lender shall to that extent not be obligated to provide
any such form or certificate and will be entitled to withdraw or cancel any affected form or
certificate, as applicable.

Section 10.2. No Waiver, Cumulative Remedies. No delay or failure on the part of the
Administrative Agent or any Lender or on the part of the holder or holders of any of the
Obligations in the exercise of any power or right under any Loan Document shall operate as a waiver
thereof or as an acquiescence in any default, nor shall any single or partial exercise of any power
or right preclude any other or further exercise thereof or the exercise of any other power or
right. The rights and remedies hereunder of the Administrative Agent, the Lenders and of the
holder or holders of any of the Obligations are cumulative to, and not exclusive of, any rights or
remedies which any of them would otherwise have.

Section 10.3. Non-Business Days. If any payment hereunder becomes due and payable on a day
which is not a Business Day, the due date of such payment shall be extended to the next succeeding
Business Day on which date such payment shall be due and payable. In the case of any payment of
principal falling due on a day which is not a Business Day, interest on such principal amount shall
continue to accrue during such extension at the rate per annum then in effect, which accrued amount
shall be due and payable on the next scheduled date for the payment of interest.

Section 10.4. Documentary Taxes. The Borrower agrees to pay on demand any documentary, stamp
or similar taxes and levies that arise from any payment made under or from the execution, delivery
or registration of, performing under or otherwise with respect to this Agreement or any other Loan
Document, including interest and penalties, in the event any such taxes are assessed, irrespective
of when such assessment is made and whether or not any credit is then in use or available
hereunder.

Section 10.5. Survival of Representations. All representations and warranties made herein or
in any other Loan Document or in certificates given pursuant hereto or thereto shall survive the
execution and delivery of this Agreement and the other Loan Documents, and shall continue in full
force and effect with respect to the date as of which they were made as long as any credit is in
use or available hereunder.

Section 10.6. Survival of Indemnities. All indemnities and other provisions relative to
reimbursement to the Lenders of amounts sufficient to protect the yield of the Lenders with respect
to the Loans and Letters of Credit, including, but not limited to, Sections 8.1, 8.4, 10.4 and
10.13 hereof, shall survive the termination of this Agreement and the other Loan Documents and the
payment of the Obligations.

Section 10.7. Sharing of Set-Off. Each Lender agrees with each other Lender a party hereto
that if such Lender shall receive and retain any payment, whether by set-off or application of
deposit balances or otherwise, on any of the Loans or Reimbursement Obligations in excess of its
ratable share of payments on all such Obligations then outstanding to the Lenders, then such Lender
shall purchase for cash at face value, but without recourse, ratably from each of the other Lenders
such amount of the Loans or Reimbursement Obligations, or participations therein, held by each such
other Lenders (or interest therein) as shall be necessary to cause such Lender to share such excess
payment ratably with all the other Lenders; provided, however, that if any such purchase is made by
any Lender, and if such excess payment or part thereof is thereafter recovered from such purchasing
Lender, the related purchases from the other Lenders shall be rescinded ratably and the purchase
price restored as to the portion of such excess payment so recovered, but without interest. For
purposes of this Section, amounts owed to or recovered by the L/C Issuer in connection with
Reimbursement Obligations in which Lenders have been required to fund their participation shall be
treated as amounts owed to or recovered by the L/C Issuer as a Lender hereunder.

Section 10.8. Notices. (a) Except as otherwise specified herein, all notices hereunder and
under the other Loan Documents shall be in writing (including, without limitation, notice by
telecopy) and shall be given to the relevant party at its address or telecopier number set forth
below, or such other address or telecopier number as such party may hereafter specify by notice to
the Administrative Agent and the Borrower given by courier, by United States certified or
registered mail, by telecopy or by other telecommunication device capable of creating a written
record of such notice and its receipt. Notices under the Loan Documents to the Lenders and the
Administrative Agent shall be addressed to their respective addresses or telecopier numbers set
forth on the signature pages hereof, and to the Borrower to:

Cleveland-Cliffs Inc

1100 Superior Avenue

Cleveland, Ohio 44114-2589

Attention: Secretary

Telephone: (216) 694-5470

Telecopy: (216) 694-6741

Each such notice, request or other communication shall be effective (i) if given by telecopier,
when such telecopy is transmitted to the telecopier number specified in this Section or on the
signature pages hereof and a confirmation of such telecopy has been received by the sender, (ii) if
given by mail, 5 days after such communication is deposited in the mail, certified or registered
with return receipt requested, addressed as aforesaid or (iii) if given by any other means, when
delivered at the addresses specified in this Section or on the signature pages hereof; provided
that any notice given pursuant to Section 2 hereof shall be effective only upon receipt.

(b) Electronic mail and internet and intranet websites may be used only to distribute routine
communications, such as financial statements, and to distribute Loan Documents for execution by the
parties thereto, and may not be used for any other purpose.

Section 10.9. Counterparts. This Agreement may be executed in any number of counterparts, and
by the different parties hereto on separate counterpart signature pages, and all such counterparts
taken together shall be deemed to constitute one and the same instrument.

Section 10.10. Successors and Assigns; Assignments and Participations. (a) Successors and
Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit
of the parties hereto and their respective successors and assigns permitted hereby, except that the
Borrower may not assign or otherwise transfer any of its rights or obligations under any Loan
Document without the prior written consent of the Administrative Agent and each Lender, and no
Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an
Eligible Assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way
of participation in accordance with the provisions of paragraph (d) of this Section or (iii) by way
of pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this
Section (and any other attempted assignment or transfer by any party hereto shall be null and
void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any
Person (other than the parties hereto, their respective successors and assigns permitted hereby,
Participants to the extent provided in paragraph (d) of this Section and, to the extent expressly
contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any
legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Assignments by Lenders. Any Lender may at any time assign to one or more Eligible
Assignees all or a portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment, its Notes and the Loans at the time owing to it); provided that

(i) except in the case of an assignment of the entire remaining amount of the assigning
Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to
a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender, the
aggregate amount of the Commitment (which for this purpose includes Loans outstanding
thereunder) or, if the applicable Commitment is not then in effect, the principal
outstanding balance of the Loans of the assigning Lender subject to each such assignment
(determined as of the date the Assignment and Assumption with respect to such assignment is
delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and
Assumption, as of the Trade Date) shall not be less than U.S. $5,000,000, in the case of any
assignment in respect of the Revolving Credit unless each of the Administrative Agent and,
so long as no Event of Default has occurred and is continuing, the Borrower otherwise
consent (each such consent not to be unreasonably withheld or delayed);

(ii) each partial assignment shall be made as an assignment of a proportionate part of
all the assigning Lender’s rights and obligations under this Agreement with respect to the
Loan or the Commitment assigned;

(iii) any assignment of a Commitment must be approved by the Administrative Agent and
the L/C Issuer unless the Person that is the proposed assignee is itself a Lender with a
Commitment (whether or not the proposed assignee would otherwise qualify as an Eligible
Assignee); and

(iv) the parties to each assignment shall execute and deliver to the Administrative
Agent an Assignment and Assumption, together with a processing and recordation fee of U.S.
$3,500, and the Eligible Assignee, if it shall not be a Lender, shall deliver to the
Administrative Agent an Administrative Questionnaire.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c)
of this Section, from and after the effective date specified in each Assignment and Assumption, the
Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest
assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this
Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by
such Assignment and Assumption, be released from its obligations under this Agreement (and, in the
case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations
under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be
entitled to the benefits of Sections 8.4 and 10.11 with respect to facts and circumstances
occurring prior to the effective date of such assignment. Any assignment or transfer by a Lender
of rights or obligations under this Agreement that does not comply with this paragraph shall be
treated for purposes of this Agreement as a sale by such Lender of a participation in such rights
and obligations in accordance with paragraph (d) of this Section.

(c) Register. The Administrative Agent, acting solely for this purpose as an agent of the
Borrower, shall maintain a copy of each Assignment and Assumption delivered to it and a register
for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal
amounts of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the
“Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative
Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the
terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to
the contrary. The Register shall be available for inspection by the Borrower and any Lender, at
any reasonable time and from time to time upon reasonable prior notice.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, the
Borrower or the Administrative Agent, sell participations to any Person (other than a natural
person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”)
in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all
or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender’s
obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations and (iii) the
Borrower, the Administrative Agent and the Lenders and L/C Issuer shall continue to deal solely and
directly with such Lender in connection with such Lender’s rights and obligations under this
Agreement.

Any agreement or instrument pursuant to which a Lender sells such a participation shall
provide that such Lender shall retain the sole right to enforce this Agreement and to approve any
amendment, modification or waiver of any provision of this Agreement; provided that such agreement
or instrument may provide that such Lender will not, without the consent of the Participant, agree
to any amendment or waiver described in Section 10.11(ii) that affects such Participant. Subject
to paragraph (e) of this Section, the Borrower agrees that each Participant shall be entitled to
the benefits of Sections 8.1 and 8.4(b) to the same extent as if it were a Lender and had acquired
its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by
law, each Participant also shall be entitled to the benefits of Section 10.14 as though it were a
Lender, provided such Participant agrees to be subject to Section 10.7 as though it were a Lender.

(e) Limitations upon Participant Rights. A Participant shall not be entitled to receive any
greater payment under Section 8.4(a) than the applicable Lender would have been entitled to receive
with respect to the participation sold to such Participant, unless the sale of the participation to
such Participant is made with the Borrower’s prior written consent. A Participant that is not a
United States person (as such term is defined in Section 7701(a)(30) of the Code) if it were a
Lender shall not be entitled to the benefits of Section 10.1(a) unless the Borrower is notified of
the participation sold to such Participant and such Participant agrees, for the benefit of the
Borrower, to comply with Section 10.1(b) as though it were a Lender.

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

(g) Electronic Execution of Assignments. The words “execution,” “signed,” “signature,” and
words of like import in any Assignment and Assumption shall be deemed to include electronic
signatures or the keeping of records in electronic form, each of which shall be of the same legal
effect, validity or enforceability as a manually executed signature or the use of a paper-based
recordkeeping system, as the case may be, to the extent and as provided for in any applicable law,
including the Federal Electronic Signatures in Global and National Commerce Act, the New York State
Electronic Signatures and Records Act, or any other similar state laws based on the Uniform
Electronic Transactions Act.

Section 10.11. Amendments. Any provision of this Agreement or the other Loan Documents may be
amended or waived if, but only if, such amendment or waiver is in writing and is signed by (a) the
Borrower, (b) the Required Lenders, and (c) if the rights or duties of the Administrative Agent or
the L/C Issuer are affected thereby, the Administrative Agent and the L/C Issuer, as the case may
be; provided that:

(i) no amendment or waiver pursuant to this Section 10.11 shall (A) increase or extend
any Commitment of any Lender without the consent of such Lender, (B) reduce the amount of or
postpone the date for any scheduled payment of any principal of or interest on any Loan or
of any Reimbursement Obligation or of any fee payable hereunder without the consent of the
Lender to which such payment is owing or which has committed to make such Loan or Letter of
Credit (or participate therein) hereunder or (C) change the application of payments set
forth in Section 2.8 hereof without the consent of any Lender adversely affected thereby;
and

(ii) no amendment or waiver pursuant to this Section 10.11 shall, unless signed by each
Lender, increase the aggregate Commitments of the Lenders, change the definitions of
Termination Date or Required Lenders, change the provisions of this Section 10.11, release
any material guarantor or all or substantially all of the collateral subject to the Liens
required by Section 4.1 hereof (except as otherwise provided for in the Loan Documents),
affect the number of Lenders required to take any action hereunder or under any other Loan
Document, or change or waive any provision of any Loan Document that provides for the pro
rata nature of disbursements by or payments to Lenders.

Section 10.12. Headings. Section headings used in this Agreement are for reference only and
shall not affect the construction of this Agreement.

Section 10.13. Costs and Expenses; Indemnification. The Borrower agrees to pay all costs and
expenses of the Administrative Agent in connection with the preparation, negotiation, syndication,
and administration of the Loan Documents, including, without limitation, the reasonable fees and
disbursements of counsel to the Administrative Agent, in connection with the preparation and
execution of the Loan Documents, and any amendment, waiver or consent related thereto, whether or
not the transactions contemplated herein are consummated, together with any fees and charges
suffered or incurred by the Administrative Agent in connection with periodic environmental audits,
fixed asset appraisals, title insurance policies, collateral filing fees and lien searches. The
Borrower further agrees to indemnify the Administrative Agent, each Lender, and their respective
directors, officers, employees, agents, financial advisors, and consultants against all Damages
(including, without limitation, all expenses of litigation or preparation therefor, whether or not
the indemnified Person is a party thereto, or any settlement arrangement arising from or relating
to any such litigation) which any of them may pay or incur arising out of or relating to any Loan
Document or any of the transactions contemplated thereby or the direct or indirect application or
proposed application of the proceeds of any Loan or Letter of Credit, other than those which arise
from the gross negligence or willful misconduct of the party claiming indemnification. The
Borrower, upon demand by the Administrative Agent or a Lender at any time, shall reimburse the
Administrative Agent or such Lender for any legal or other expenses incurred in connection with
investigating or defending against any of the foregoing (including any settlement costs relating to
the foregoing) except if the same is directly due to the gross negligence or willful misconduct of
the party to be indemnified. The obligations of the Borrower under this Section shall survive the
termination of this Agreement.

Section 10.14. Set-off. In addition to any rights now or hereafter granted under applicable
law and not by way of limitation of any such rights, upon the occurrence of any Event of Default,
each Lender and each subsequent holder of any Obligation is hereby authorized by the Borrower at
any time or from time to time, without notice to the Borrower or to any other Person, any such
notice being hereby expressly waived, to set-off and to appropriate and to apply any and all
deposits (general or special, including, but not limited to, indebtedness evidenced by certificates
of deposit, whether matured or unmatured, but not including trust accounts, and in whatever
currency denominated) and any other indebtedness at any time held or owing by that Lender or that
subsequent holder to or for the credit or the account of the Borrower, whether or not matured,
against and on account of the Obligations of the Borrower to that Lender or that subsequent holder
under the Loan Documents, including, but not limited to, all claims of any nature or description
arising out of or connected with the Loan Documents, irrespective of whether or not (a) that Lender
or that subsequent holder shall have made any demand hereunder or (b) the principal of or the
interest on the Loans or Notes and other amounts due hereunder shall have become due and payable
pursuant to Section 7 and although said obligations and liabilities, or any of them, may be
contingent or unmatured.

Section 10.15. Entire Agreement. The Loan Documents constitute the entire understanding of
the parties thereto with respect to the subject matter thereof and any prior agreements, whether
written or oral, with respect thereto are superseded hereby.

Section 10.16. Governing Law. This Agreement and the other Loan Documents, and the rights and
duties of the parties hereto, shall be construed and determined in accordance with the internal
laws of the State of Ohio.

Section 10.17. Severability of Provisions. Any provision of any Loan Document which is
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such unenforceability without invalidating the remaining provisions hereof or affecting the
validity or enforceability of such provision in any other jurisdiction. All rights, remedies and
powers provided in this Agreement and the other Loan Documents may be exercised only to the extent
that the exercise thereof does not violate any applicable mandatory provisions of law, and all the
provisions of this Agreement and other Loan Documents are intended to be subject to all applicable
mandatory provisions of law which may be controlling and to be limited to the extent necessary so
that they will not render this Agreement or the other Loan Documents invalid or unenforceable.

Section 10.18. Excess Interest. Notwithstanding any provision to the contrary contained
herein or in any other Loan Document, no such provision shall require the payment or permit the
collection of any amount of interest in excess of the maximum amount of interest permitted by
applicable law to be charged for the use or detention, or the forbearance in the collection, of all
or any portion of the Loans or other obligations outstanding under this Agreement or any other Loan
Document (“Excess Interest”). If any Excess Interest is provided for, or is adjudicated to be
provided for, herein or in any other Loan Document, then in such event (a) the provisions of this
Section shall govern and control, (b) the Borrower nor any guarantor or endorser shall be obligated
to pay any Excess Interest, (c) any Excess Interest that the Administrative Agent or any Lender may
have received hereunder shall, at the option of the Administrative Agent, be (i) applied as a
credit against the then outstanding principal amount of Obligations hereunder and accrued and
unpaid interest thereon (not to exceed the maximum amount permitted by applicable law), (ii)
refunded to the Borrower, or (iii) any combination of the foregoing, (d) the interest rate payable
hereunder or under any other Loan Document shall be automatically subject to reduction to the
maximum lawful contract rate allowed under applicable usury laws (the “Maximum Rate”), and this
Agreement and the other Loan Documents shall be deemed to have been, and shall be, reformed and
modified to reflect such reduction in the relevant interest rate, and (e) neither the Borrower nor
any guarantor or endorser shall have any action against the Administrative Agent or any Lender for
any Damages whatsoever arising out of the payment or collection of any Excess Interest.
Notwithstanding the foregoing, if for any period of time interest on any of the Borrower’s
Obligations is calculated at the Maximum Rate rather than the applicable rate under this Agreement,
and thereafter such applicable rate becomes less than the Maximum Rate, the rate of interest
payable on the Borrower’s Obligations shall remain at the Maximum Rate until the Lenders have
received the amount of interest which such Lenders would have received during such period on the
Borrower’s Obligations had the rate of interest not been limited to the Maximum Rate during such
period.

Section 10.19. Construction. The parties acknowledge and agree that the Loan Documents shall
not be construed more favorably in favor of any party hereto based upon which party drafted the
same, it being acknowledged that all parties hereto contributed substantially to the negotiation of
the Loan Documents. Nothing contained herein shall be deemed or construed to permit any act or
omission which is prohibited by the terms of the Pledge Agreements, the covenants and agreements
contained herein being in addition to and not in substitution for the covenants and agreements
contained in the Pledge Agreements.

Section 10.20. Lender’s Obligations Several. The obligations of the Lenders hereunder are
several and not joint. Nothing contained in this Agreement and no action taken by the Lenders
pursuant hereto shall be deemed to constitute the Lenders a partnership, association, joint venture
or other entity.

Section 10.21. USA Patriot Act. Each Lender hereby notifies the Borrower that pursuant to the
requirements of the Patriot Act it is required to obtain, verify and record information that
identifies the Borrower, which information includes the name and address of the Borrower and other
information that will allow such Lender to identify the Borrower in accordance with the Patriot
Act.

Section 10.22. Currency. Each reference in this Agreement to U.S. Dollars or to an
Alternative Currency (the “relevant currency”) is of the essence. To the fullest extent permitted
by law, the obligation of the Borrower in respect of any amount due in the relevant currency under
this Agreement shall, notwithstanding any payment in any other currency (whether pursuant to a
judgment or otherwise), be discharged only to the extent of the amount in the relevant currency
that the Person entitled to receive such payment may, in accordance with normal banking procedures,
purchase with the sum paid in such other currency (after any premium and costs of exchange) on the
Business Day immediately following the day on which such Person receives such payment. If the
amount of the relevant currency so purchased is less than the sum originally due to such Person in
the relevant currency, the Borrower agrees, as a separate obligation and notwithstanding any such
judgment, to indemnify such Person against such loss, and if the amount of the specified currency
so purchased exceeds the sum of (a) the amount originally due to the relevant Person in the
specified currency plus (b) any amounts shared with other Lenders as a result of allocations of
such excess as a disproportionate payment to such Person under Section 10.7 hereof, such Person
agrees to remit such excess to the Borrower.

Section 10.23. Submission to Jurisdiction; Waiver of Jury Trial. The Borrower hereby submits
to the nonexclusive jurisdiction of the United States District Court for the Southern District of
Ohio and of any Ohio State court sitting in the City of Cincinnati for purposes of all legal
proceedings arising out of or relating to this Agreement, the other Loan Documents or the
transactions contemplated hereby or thereby. The Borrower irrevocably waives, to the fullest
extent permitted by law, any objection which it may now or hereafter have to the laying of the
venue of any such proceeding brought in such a court and any claim that any such proceeding brought
in such a court has been brought in an inconvenient forum. The Borrower, the Administrative
Agent, the L/C Issuer and the Lenders hereby irrevocably waive any and all right to trial by jury
in any legal proceeding arising out of or relating to any Loan Document or the transactions
contemplated thereby.
