2.7Method of Selecting Types and Interest Periods for Portions on Closing
Date.Borrower shall select the Type of Portion and, in the case of each Eurodollar Portion, the Interest Period applicable thereto from time to time. Borrower
shall give Agent irrevocable notice (an "Initial Notice") not later than 12:00 p.m. (Chicago time) at least one Business Day before the Closing Date with respect to each Floating Rate Portion
and three Business Days before the Closing Date with respect to each Eurodollar Portion, specifying:



2.8Conversion and Continuation of Outstanding Portions.Floating Rate Portions shall
continue as Floating Rate Portions unless and until such Floating Rate Portions are converted into Eurodollar Portions pursuant to this Section 2.6 or are repaid in accordance with
Section 2.8. Each Eurodollar Portion shall continue as a Eurodollar Portion until the end of the then applicable Interest Period therefor, at which time such Eurodollar Portion shall be
automatically converted into a Floating Rate Portion unless (x) such Eurodollar Portion is or was repaid in accordance with Section 2.6 or (y) Borrower shall have given Agent a
Conversion/Continuation Notice (as defined below) requesting that, at the end of such Interest Period, such Eurodollar Portion continue as a Eurodollar Portion for the same or another Interest Period.
Subject to the terms of Section 2.5, Borrower may elect from time to time to convert all or any part of a Floating Rate Portion into a Eurodollar Portion. Borrower shall give Agent irrevocable
notice (a "Conversion/Continuation Notice") of each conversion of a Floating Rate Portion into a Eurodollar Portion or continuation of a Eurodollar Portion not later than 12:00 p.m. (Chicago
time) at least three Business Days prior to the date of the requested conversion or continuation, specifying:



12

---



2.9Changes in Interest Rate.Each Floating Rate Portion shall bear interest on the
outstanding principal amount thereof for each day from and including the date such Portion is designated or is automatically converted from a Eurodollar Portion into a Floating Rate Portion pursuant
to Section 2.8, to but excluding the date it is paid or is converted into a Eurodollar Portion pursuant to Section 2.8 hereof, at a rate per annum equal to the Floating Rate for such
day. Changes in the rate of interest on any Portion maintained as a Floating Rate Portion will take effect simultaneously with each change in the Alternate Base Rate. Each Eurodollar Portion shall
bear interest on the outstanding principal amount thereof for each day from and including the first day of the Interest Period applicable thereto to (but not including) the last day of such Interest
Period at the interest rate determined by Agent as applicable to such Eurodollar Portion based upon the Borrower's selections under Sections 2.7 and 2.8, any changes in the Applicable Margin
and otherwise in accordance with the terms hereof. No Interest Period may end after the Maturity Date and no Interest Period for any LTV Increase Amount may end after the due date thereof.

2.10Rates Applicable After Default.Notwithstanding anything to the contrary contained
in Section 2.7, 2.8 or 2.9, during the continuance of a Default or Unmatured Default the Required Lenders may, at their option, by notice to Borrower (which notice may be revoked at the option
of the Required Lenders notwithstanding any provision of Section 8.2 requiring unanimous consent of the Lenders to changes in interest rates), declare that no Portion may be made as, converted
into or continued as a Eurodollar Portion. During the continuance of a Default the Required Lenders may, at their option, by notice to the Borrower (which notice may be revoked at the option of the
Required Lenders notwithstanding any provision of Section 8.2 requiring unanimous consent of the Lenders to changes in interest rates), declare that the outstanding principal balance of the
Loans (whether theretofore consisting of one or more Eurodollar Portions or Floating Rate Portions) shall thereafter bear interest at a rate per annum equal to the Alternative Base Rate in effect from
time to time, plus 5%,providedthat, during the continuance of a Default under Section 7.4 or 7.5, the default interest rate set forth herein
shall be applicable to the Loan without any election or action on the part of Agent or any Lender.

2.11Method of Payment.All payments of the Obligations hereunder shall be made, without
setoff, deduction, or counterclaim, in immediately available funds to Agent at Agent's address specified pursuant to Article XIII, or at any other Lending Installation of Agent specified in
writing by Agent to the Borrower, by noon (local time) on the date when due and shall be applied ratably by Agent among the Lenders. Each payment delivered to Agent for the account of any Lender shall
be delivered promptly by Agent to such Lender in the same type of funds that Agent received at its address specified pursuant to Article XIII or at any Lending Installation specified in a
notice received by Agent from such Lender. Agent is hereby authorized to charge any accounts of the Borrower maintained with Bank One for each payment of principal, interest and fees as the same
become due hereunder.

2.12Evidence of Indebtedness.



2.13Telephonic Notices.The Borrower hereby authorizes the Lenders and Agent to convert
or continue Portions, effect selections of Types of Portions and to transfer funds based on telephonic notices made by any person or persons Agent or any Lender in good faith believes to be acting on
behalf of the Borrower, it being understood that the foregoing authorization is specifically intended to allow the Initial Notice and Conversion/Continuation Notices to be given telephonically. The
Borrower agrees to deliver promptly to Agent a written confirmation, if such confirmation is requested by Agent or any Lender, of each telephonic notice signed by an

13

---

Authorized
Officer. If the written confirmation differs in any material respect from the action taken by Agent and the Lenders, the records of Agent and the Lenders shall govern absent manifest error.

2.14Interest Payment Dates; Interest and Fee Basis.Interest accrued on each Portion
shall be payable on each Payment Date, commencing with the first such Payment Date to occur after the Closing Date, on any date on which a Portion is prepaid, whether due to acceleration or otherwise,
and on the Maturity Date. Notwithstanding the foregoing, interest accrued on that portion of the outstanding principal amount of any Floating Rate Portion converted into a Eurodollar Portion on a day
other than a Payment Date shall be payable on the date of conversion. Interest shall be calculated for actual days elapsed on the basis of a 360-day year. Interest shall be payable for the
day a Portion is established but not for the day of any payment on the amount paid if payment is received prior to noon (local time) at the place of payment. If any payment of principal of or interest
on a Portion shall become due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day and, in the case of a principal payment, such extension of time shall
be included in computing interest in connection with such payment.

2.15Notification of Interest Rates and Prepayments.Promptly after receipt thereof,
Agent will notify each Lender of the contents of the Initial Notice, any Conversion/Continuation Notice and any repayment notice received by it hereunder. Agent will notify each Lender of the interest
rate applicable to each Eurodollar Portion promptly upon determination of such interest rate and will give each Lender prompt notice of each change in the Alternate Base Rate.

2.16Lending Installations.Each Lender may book its Loans at any Lending Installation
selected by such Lender and may change its Lending Installation from time to time. All terms of this Agreement shall apply to any such Lending Installation and the Loans and any Notes issued hereunder
shall be deemed held by each Lender for the benefit of any such Lending Installation. Each Lender may, by written notice to Agent and the Borrower in accordance with Article XIII, designate
replacement or additional Lending Installations for whose account Loan payments are to be made.

2.17Non-Receipt of Funds by Agent.Unless the Borrower notifies Agent prior
to the date on which it is scheduled to make payment to Agent of a payment of principal, interest or fees to Agent for the account of the Lenders, that it does not intend to make such payment, Agent
may assume that such payment has been made. Agent may, but shall not be obligated to, make the amount of such payment available to the intended recipient in reliance upon such assumption. If the
Borrower has not in fact made such payment to Agent, the recipient of such payment shall, on demand by Agent, repay to Agent the amount so made available together with interest thereon in respect of
each day during the period commencing on the date such amount was so made available by Agent until the date Agent recovers such amount at a rate per annum equal to in the case of payment by the
Borrower, the interest rate applicable to the relevant Loan.

2.18Usury.All agreements herein are expressly limited so that in no contingency or
event whatsoever, whether by reason of the disbursement of the proceeds of the Loans, the acceleration of the maturity of the unpaid principal balance of the Loans, or otherwise, shall the amount paid
or agreed to be paid to the Lenders for the use, forbearance or detention of the money to be advanced under the Loan exceed the highest lawful rate permissible under applicable usury laws. If, from
any circumstances whatsoever, the fulfillment of any provision of this Agreement or any of the other Loan Documents, at the time performance of such provision shall be due, shall involve transcending
the limit of validity prescribed by law which a court of competent jurisdiction may deem applicable to the Loan, then, ipso facto, the obligation to be fulfilled shall be reduced to the limit of such
validity; and if, from any circumstance, any Lender shall ever receive as interest an amount which would exceed the highest lawful rate, such amount which would be excessive interest shall be applied
to the reduction of such Lender's portion of the unpaid principal balance due on the Loan and not to the payment of interest.

2.19Late Charges.If any payment of interest or principal is not received by Agent
within five (5) days after the date such payment is due, then at the option of Agent, in addition to the remedies conferred upon Agent pursuant to this Agreement and the other Loan Documents, a
late charge of five percent (5%) of the amount of the regularly scheduled payment or $25.00, whichever is greater, will be added to the delinquent amount to compensate Agent for the expense of
handling the delinquency for any payment past due in excess of ten (10) days, regardless of any notice and cure periods. Such Late Charge is an administrative charge that will be 100% retained
by Agent and not paid to the Lenders.

2.20Closing Costs and Expenses.In addition to the commitment fees payable as provided
in Section 2.4 above, Borrower shall pay, on or prior to the Closing Date, all closing costs and other fees and expenses incurred

14

---

by
Agent in connection with the Loans (including Appraisal fees, title insurance premiums, escrow fees, recording fees, out of pocket syndication expenses and attorneys' fees and expenses), and other
expenses as provided herein. Borrower hereby acknowledges and agrees that the commitment fee does not include payment of any such costs, fees or expenses.

ARTICLE III        YIELD PROTECTION; TAXES

3.1Yield Protection.If, on or after the date of this Agreement, the adoption of any
law or any governmental or quasi-governmental rule, regulation, policy, guideline or directive (whether or not having the force of law), or any change in the interpretation or administration thereof
by any governmental or quasi-governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender or applicable Lending
Installation with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency:



and
the result of any of the foregoing is to increase the cost to such Lender or applicable Lending Installation of making or maintaining its Eurodollar Portions or to reduce the return received by
such Lender or applicable Lending Installation in connection with such Eurodollar Portions, then, within 15 days of demand by such Lender, the Borrower shall pay such Lender such additional
amount or amounts as will compensate such Lender for such increased cost or reduction in amount received.

3.2Intentionally Omitted.

3.3Availability of Types of Portions.If any Lender determines that maintenance of
Eurodollar Portions at a suitable Lending Installation would violate any applicable law, rule, regulation, or directive, whether or not having the force of law, or if the Required Lenders determine
that (i) deposits of a type and maturity appropriate to match fund Eurodollar Portions are not available, or (ii) the interest rate applicable to Eurodollar Portions does not accurately
reflect the cost of making or maintaining Eurodollar Portions, then Agent shall suspend the availability of Eurodollar Portions and require any affected Eurodollar Portions to be repaid or converted
to Floating Rate Portions.

3.4Funding Indemnification.If any payment of a Eurodollar Portion occurs on a date
which is not the last day of the applicable Interest Period, whether because of acceleration, prepayment or otherwise, the Borrower will indemnify each Lender for any loss or cost incurred by it
resulting therefrom, including, without limitation, any loss or cost in liquidating or employing deposits acquired to fund or maintain such Eurodollar Portion.

3.5Taxes.



16

---



3.6Lender Statements; Survival of Indemnity.To the extent reasonably possible, each
Lender shall designate an alternate Lending Installation with respect to its Eurodollar Portions to reduce any liability of the Borrower to such Lender under Sections 3.1 and 3.5 or to avoid
the unavailability of Eurodollar Portions under Section 3.3, so long as such designation is not, in the judgment of such Lender, disadvantageous to such Lender.

17

---

Each
Lender shall deliver a written statement of such Lender to the Borrower (with a copy to Agent) as to the amount due, if any, under Section 3.1, 3.4 or 3.5. Such written statement shall set
forth in reasonable detail the calculations upon which such Lender determined such amount and shall be final, conclusive and binding on the Borrower in the absence of actual error. Determination of
amounts payable under such Sections in connection with a Eurodollar Portion shall be calculated as though each Lender funded its Eurodollar Portion through the purchase of a deposit of the type and
maturity corresponding to the deposit used as a reference in determining the Eurodollar Rate applicable to such Loan, whether in fact that is the case or not. Unless otherwise provided herein, the
amount specified in the written statement of any Lender shall be payable on demand after receipt by the Borrower of such written statement. The obligations of the Borrower under Sections 3.1,
3.4 and 3.5 shall survive payment of the Obligations and termination of this Agreement.

respect of the Obligations to the applicable Lender and for all other purposes shall deal directly with the Lenders. No successor Agent shall be deemed to be appointed hereunder until such
successor Agent has accepted the appointment. Any such successor Agent shall be a commercial bank having capital and retained earnings of at least $100,000,000. Upon the acceptance of any appointment
as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the resigning or removed Agent. Upon
the effectiveness of the resignation or removal of Agent, the resigning or removed Agent shall be discharged from its duties and obligations hereunder and under the Loan Documents. After the
effectiveness of the resignation or removal of an Agent, the provisions of this Article X shall continue in effect for the benefit of such Agent in respect of any actions taken or omitted to be
taken by it while it was acting as Agent hereunder and under the other Loan Documents. In the event that there is a successor to Agent by merger, or Agent assigns its duties and obligations to an
Affiliate pursuant to this Section 10.12, then the term "Prime Rate" as used in this Agreement shall mean the prime rate, base rate or other analogous rate of the new Agent.

10.13Delegation to Affiliates.The Borrower and the Lenders agree that Agent may
delegate any of its duties under this Agreement to any of its Affiliates. Any such Affiliate (and such Affiliate's directors, officers, agents and employees) which performs duties in connection with

10.14Collateral Property Releases.The Lenders hereby empower and authorize Agent to
execute and deliver to the Borrower on their behalf any agreements, documents or instruments as shall be necessary or appropriate to effect any releases of a Property Collateral which shall be

ARTICLE XI        SETOFF; RATABLE PAYMENTS

11.1Setoff.In addition to, and without limitation of, any rights of the Lenders under
applicable law, if the Borrower becomes insolvent, however evidenced, or any Default occurs, any and all deposits (including all account balances, whether provisional or final and whether or not
collected or available) and any other Indebtedness at any time held or owing by any Lender or any Affiliate of any Lender to or for the credit or account of the Borrower may be offset and applied
toward the payment of the Obligations owing to such Lender, whether or not the Obligations, or any part thereof, shall then be due.

11.2Ratable Payments.If any Lender, whether by setoff or otherwise, has payment made
to it upon its Loans (other than payments received pursuant to Section 3.1, 3.4 or 3.5) in a greater proportion than that received by any other Lender, such Lender agrees, promptly upon demand,
to purchase a portion of the Loans held by the other Lenders so that after such purchase each Lender will hold its ratable proportion of Loans. If any Lender, whether in connection with setoff or
amounts which might be subject to setoff or otherwise, receives collateral or other protection for its Obligations or such amounts which may be subject to setoff, such Lender agrees, promptly upon
demand, to take such action necessary such that all Lenders share in the benefits of such collateral ratably in proportion to their Loans. In case any such payment is disturbed by legal process, or
otherwise, appropriate further adjustments shall be made.

ARTICLE XII        BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

12.1Successors and Assigns.The terms and provisions of the Loan Documents shall be
binding upon and inure to the benefit of the Borrower and the Lenders and their respective successors and assigns permitted hereby, except that (i) the Borrower shall not have the right to
assign its rights or obligations under the Loan Documents without the prior written consent of each Lender, (ii) any assignment by any Lender must be made in compliance with
Section 12.3, and (iii) any transfer by Participation must be made in compliance with Section 12.2. Any attempted assignment or transfer by any party not made in compliance with
this Section 12.1 shall be null and void, unless such attempted assignment or transfer is treated as a participation in accordance with Section 12.3(c). The parties to this Agreement
acknowledge that clause (ii) of this Section 12.1 relates only to absolute assignments and this Section 12.1 does not prohibit assignments creating security interests, including,
without limitation, (x) any pledge or assignment by any Lender of all or any portion of its rights under this Agreement and any Note to a Federal Reserve Bank or (y) in the case of a
Lender which is a Fund, any pledge or assignment of all or any portion of its rights under this Agreement and any Note to its trustee in support of its obligations to its trustee; provided, however,that no such pledge or assignment creating a security interest shall release the transferor Lender from its obligations hereunder
unless and until the parties thereto have complied with the provisions of Section 12.3. Agent may treat the Person which made any Loan or which holds any Note as the owner thereof for all
purposes hereof unless and until such Person complies with Section 12.3;provided, however,that Agent may in its discretion (but shall not be
required to) follow instructions from the Person which made any Loan or which holds any Note to direct payments relating to such Loan or Note to another Person. Any assignee of the rights to any Loan
or any Note agrees by acceptance of such assignment to be bound by all the terms and provisions of the Loan Documents. Any request, authority or consent of any Person, who at the time of making such
request or giving such authority or consent is the owner of the rights to any Loan (whether or not a Note has been issued in evidence thereof), shall be conclusive and binding on any subsequent holder
or assignee of the rights to such Loan.

12.2Participations.

(a)Permitted Participants; Effect.Any Lender may at any time sell to one or more banks
or other entities ("Participants") participating interests in the Loan owing to such Lender, any Note held by such Lender or any other interest of such Lender under the Loan Documents. In the event of
any such sale by a Lender of participating interests to a Participant, such Lender's obligations under the Loan Documents shall remain unchanged, such Lender shall remain solely responsible to the
other parties hereto for the performance of such
obligations, such Lender shall remain the owner of its Loan and the holder of any Note issued to it in evidence thereof for all purposes under the Loan Documents, all amounts payable by the Borrower
under this Agreement shall be determined as if such Lender had not sold such participating interests, and the Borrower and Agent shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under the Loan Documents.

(b)Voting Rights.Each Lender shall retain the sole right to approve, without the
consent of any Participant, any amendment, modification or waiver of any provision of the Loan Documents, other than any amendment, modification or waiver with respect to any Loan in which such
Participant has an interest which would require consent of all of the Lenders pursuant to the terms of Section 8.2 or of any other Loan Document.

(c)Benefit of Certain Provisions.The Borrower agrees that each Participant shall be
deemed to have the right of setoff provided in Section 11.1 in respect of its participating interest in amounts owing under the Loan Documents to the same extent as if the amount of its
participating interest were owing directly to it as a Lender under the Loan Documents,providedthat each Lender shall retain the right of setoff
provided in Section 11.1 with respect to the amount of participating interests sold to each Participant. The Lenders agree to share with each Participant, and each Participant, by exercising
the right of setoff provided in Section 11.1, agrees to share with each Lender, any amount received pursuant to the exercise of its right of setoff, such amounts to be shared in accordance with
Section 11.2 as if each Participant were a Lender. The Borrower further agrees that each Participant shall be entitled to the benefits of Sections 3.1, 3.4 and 3.5 to the same extent as
if it were a Lender and had acquired its interest by assignment pursuant to Section 12.3,providedthat (i) a Participant shall not be
entitled to receive any greater payment under Section 3.1 or 3.5 than the Lender who sold the participating interest to such Participant would have received had it retained such interest for
its own account, unless the sale of such interest to such Participant is made with the prior written consent of the Borrower, and (ii) any Participant not incorporated under the laws of the
United States of America or any State thereof agrees to comply with the provisions of Section 3.5 to the same extent as if it were a Lender.

12.3Assignments.

(a)Permitted Assignments.Any Lender may at any time assign to one or more banks or
other entities ("Purchasers") all or any part of its rights and obligations under this Agreement and the other Loan Documents. Such assignment shall be substantially in the form of Exhibit B or
in such other form as may be agreed to by the parties thereto. Each such assignment with respect to a Purchaser which is not a Lender or an Affiliate of a Lender or an Approved Fund shall be in an
amount not less than the lesser of (i) $5,000,000, or (ii) the assigning Lender's Pro Rata Share of the Available Amount. Following any assignment by a Lender provided for herein,
Borrower shall be deemed to have released the assigning Lender for the amount so assigned.

(b)Consents.Unless the Purchaser is a Lender, an Affiliate of a Lender or an Approved
Fund, (i) the consent of Agent shall be required prior to an assignment becoming effective, and (ii) unless a Default or Unmatured Default then exists or the assignment is in connection
with the physical settlement of credit derivative transactions, the consent of Borrower shall be required prior to an assignment becoming effective. Any consent required under this
Section 12.3(b) shall not be unreasonably withheld or delayed.

(c)Effect; Effective Date.Upon (i) delivery to Agent of an assignment, together
with any consents required by Sections 12.3(a) and 12.3(b), and (ii) payment of a $3,500 fee from the Purchaser to Agent for processing such assignment (unless such fee is waived by
Agent), such assignment shall become effective on the effective date specified in such assignment. The assignment shall contain a representation by the Purchaser to the effect that none of the
consideration used to make the purchase of the Available Amount and Loans under the applicable assignment agreement constitutes "plan assets" as defined under ERISA and that the rights and interests
of the Purchaser in and under the Loan Documents will not be "plan assets" under ERISA. On and after the effective date of such assignment, such Purchaser shall for all purposes be a Lender party to
this Agreement and any other Loan Document executed by or on behalf of the Lenders and shall have all the rights and obligations of a Lender under the Loan Documents, to the same extent as if it were
an original party thereto, and the transferor Lender shall be released with respect to the Available Amount and Loans assigned to such Purchaser without any further consent or action by the Borrower,
the Lenders or Agent. In the case of an assignment covering all of the assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a Lender hereunder but shall
continue to be entitled to the benefits of, and subject to, those provisions of this Agreement and the other Loan Documents which survive payment of the Obligations and termination of the applicable
agreement. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 12.3 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 Section 12.2. Upon the consummation of any assignment to a Purchaser pursuant to this
Section 12.3(c), the transferor Lender, Agent and the Borrower shall, if the transferor Lender or the Purchaser desires that its Loans be evidenced by Notes, make appropriate arrangements so
that new Notes or, as appropriate, replacement Notes are issued to such transferor Lender and new Notes or, as appropriate, replacement Notes, are issued to such Purchaser, in each case in principal
amounts reflecting their respective Loans and Available Amount, as adjusted pursuant to such assignment.

(d)Register.Agent, acting solely for this purpose as an agent of the Borrower, shall
maintain at one of its offices in Chicago, Illinois 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
Available Amount 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, 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.

12.4Dissemination of Information.The Borrower authorizes each Lender to disclose to
any Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by operation of law (each a "Transferee") and any prospective Transferee any and all information in such
Lender's possession concerning the creditworthiness of the Borrower and its Subsidiaries, including without limitation any information contained in any Reports; providedthat each Transferee and
prospective Transferee agrees to be bound by Section 9.11 of this Agreement.

12.5Tax Treatment.If any interest in any Loan Document is transferred to any
Transferee which is not incorporated under the laws of the United States or any State thereof, the transferor Lender shall cause such Transferee, concurrently with the effectiveness of such transfer,
to comply with the provisions of Section 3.5(iv).

OF AGENT OR ANY LENDER INVOLVING, DIRECTLY OR
INDIRECTLY, ANY MATTER IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT SHALL BE BROUGHT ONLY IN A COURT IN COLUMBUS, OHIO.

15.3WAIVER OF JURY TRIAL.THE BORROWER,

IN WITNESS WHEREOF, the Borrower, the Lenders and Agent have executed this Agreement as of the date first above
written.
