SECTION 2

THE COMMITMENTS AND EXTENSIONS OF CREDIT

2.01    Loans; Maximum Amounts.

(a)   Subject to the terms and conditions set forth in this Agreement, each Lender severally agrees to make, Convert and Continue Loans until the Maturity Date in such amounts as Borrower may from time to time request; provided, however, that the
Outstanding Obligations of each Lender shall not exceed at any time such Lender’s Commitment, and the Outstanding Obligations of all Lenders shall not exceed at any time the lesser of (i) the combined Commitments; and (ii) the Availability Limit.  This is
a revolving credit and, subject to the foregoing and the other terms and conditions hereof, Borrower may borrow, Convert, Continue, prepay and reborrow Loans as set forth herein without premium or penalty.

(b)   Loans made by each Lender shall be evidenced by one or more Notes.  The date, amount and maturity of each Lender’s Loans and payments and other particulars with respect thereto may be endorsed on schedule(s) attached to its Note by
each Lender and/or recorded on one or more loan accounts or records maintained by such Lender in the ordinary course of business.  Such Notes, loan accounts and records shall be conclusive absent manifest error of the amount of such Loans and payments
thereon.  Any failure so to record or any error in doing so shall not, however, limit or otherwise affect the obligation of Borrower to pay any amount owing with respect to the Loans.

25

2.02    Borrowings, Conversions and Continuations of Loans.

(a)   Borrower may irrevocably request a Borrowing, Conversion or Continuation of Loans in a Minimum Amount therefor by delivering a Request for Extension of Credit therefor by Requisite Notice to Administrative Agent not later than the Requisite
Time therefor.  All Borrowings, Conversions and Continuations of Loans shall constitute Base Rate Loans unless properly and timely otherwise designated as set forth in the prior sentence.

(b)   Following receipt of a Request for Extension of Credit, Administrative Agent shall promptly notify each Lender of its Pro Rata Share thereof by Requisite Notice.  In the case of a Borrowing of Loans, each Lender shall make the funds for
its Loan available to Administrative Agent at Administrative Agent’s Office not later than the Requisite Time therefor on the Business Day specified in such Request for Extension of Credit.  Upon satisfaction of the applicable conditions set forth in
Section 4.02 (and, if the initial Extension of Credit hereunder, Section 4.01), all funds so received shall be made available to Borrower in Dollars.  Administrative Agent shall promptly notify Borrower and Lenders of the interest rate applicable to any Loan
other than a Base Rate Loan upon determination of same.

(c)   Except as otherwise provided herein, an Offshore Rate Loan may be Continued or Converted only on the last day of the Interest Period for such Offshore Rate Loan.  During the existence of a Default or Event of Default, no Loans may be
requested as, Converted into or Continued as Offshore Rate Loans without the consent of Requisite Lenders, and Requisite Lenders may demand that any or all of the then outstanding Offshore Rate Loans be Converted immediately into Base Rate Loans.

(d)   If a Loan is to be made on the same date that another Loan is due and payable, Borrower or Lenders, as the case may be, shall, unless Administrative Agent otherwise requests, make available to Administrative Agent the net amount of funds
giving effect to both such Loans and the effect for purposes of this Agreement shall be the same as if separate transfers of funds had been made with respect to each such Loan.

(e)   The failure of any Lender to make any Loan on any date shall not relieve any other Lender of any obligation to make a Loan on such date, but no Lender shall be responsible for the failure of any other Lender to so make its Loan.

2.03    Letters of Credit.

(a)   The Letter of Credit Sublimit.  Subject to the terms and conditions set forth in this Agreement, until the Letter of Credit Expiration Date, Issuing Lender shall take such Letter of Credit Actions as Borrower may from time to time
request; provided, however, that (i) the Outstanding Obligations of each Lender shall not at any time exceed such Lender’s Commitment; (ii) the Outstanding Obligations of all Lenders shall not at any time exceed the lesser of (x) the combined Commitments; and
(y) the Availability Limit; and (iii) Letter of Credit Usage shall not at any time exceed the Letter of Credit Sublimit.  Subject to subsection (g) below and unless consented to by Issuing Lender and Requisite Lenders, no Letter of Credit may expire more than 12
months after the date of its issuance or last renewal.  No Letter of Credit shall expire after the Letter of Credit Expiration Date except that, at the option of Administrative

26

Agent, Letters of Credit securing Borrower's obligations pursuant to workers' compensation claims may have an expiration date not to exceed six (6) months after the Letter of Credit Expiration Date provided that (A) the aggregate face amount of such Letters of
Credit shall not exceed $2,000,000; and (B) from and after the Letter of Credit Expiration Date, the Letter of Credit Usage under such Letters of Credit shall be fully secured by cash collateral in an amount equal to such Letter of Credit Usage deposited in a Letter
of Credit Cash Collateral Account.

(b)   Letter of Credit Actions.  Subject to the terms and conditions set forth in this Agreement, until the Letter of Credit Expiration Date, Issuing Lender shall take such Letter of Credit Actions as Borrower may from time to time
request; provided, however, that the Outstanding Obligations of each Lender shall not exceed such Lender’s Commitment, and the Outstanding Obligations of all Lenders shall not exceed the combined Commitments at any time.  Subject to subsection (g) below
and unless consented to by Issuing Lender and Requisite Lenders, no Letter of Credit may expire more than 12 months after the date of its issuance or last renewal; provided, however, that no Letter of Credit shall expire after the Letter of Credit Expiration
Date.

(c)   Requesting Letter of Credit Actions.  Borrower may irrevocably request a Letter of Credit Action in a Minimum Amount therefor by delivering a Letter of Credit Application therefor to Issuing Lender, with a copy to Administrative
Agent (who shall notify Lenders), by Requisite Notice not later than the Requisite Time therefor.  Each Letter of Credit Action shall be in a form acceptable to Issuing Lender in its sole discretion.  Unless Administrative Agent notifies Issuing Lender that
such Letter of Credit Action is not permitted hereunder, or Issuing Lender notifies Administrative Agent that it has determined that such Letter of Credit Action is contrary to any Laws or policies of Issuing Lender, Issuing Lender shall, upon satisfaction of the
applicable conditions set forth in Section 4.02 with respect to any Letter of Credit Action constituting an Extension of Credit, effect such Letter of Credit Action.  This Agreement shall control in the event of any conflict with any Letter of Credit
Application. Upon the issuance of a Letter of Credit, each Lender shall be deemed to have purchased from Issuing Lender a risk participation therein in an amount equal to such Lender’s Pro Rata Share times the amount of such Letter of Credit.

(d)   Reimbursement of Payments Under Letters of Credit.  Borrower shall reimburse Issuing Lender through Administrative Agent for any payment that Issuing Lender makes under a Letter of Credit on or before the date of such payment;
provided, however, that if the conditions precedent set forth in Section 4.02 can be satisfied, Borrower may request a Borrowing of Loans to reimburse Issuing Lender for such payment pursuant to Section 2.02, or, failing to make such request, Borrower shall be deemed
to have requested a Borrowing of Base Rate Loans on such payment date pursuant to subsection (e) below.

(e)   Funding by Lenders When Issuing Lender Not Reimbursed.  Upon any drawing under a Letter of Credit, Issuing Lender shall notify Administrative Agent and Borrower.  If Borrower fails to timely make the payment required pursuant
to subsection (c) above, Issuing Lender shall notify Administrative Agent of such fact and the amount of such unreimbursed payment.  Administrative Agent shall promptly notify each Lender of its Pro Rata Share of such amount by Requisite Notice.  Each
Lender shall make funds in an amount equal its Pro Rata Share of such amount available to Administrative Agent at Administrative Agent’s

27

Office not later than the Requisite Time therefor on the Business Day specified by Administrative Agent,  Administrative Agent shall remit the funds so received to Issuing Lender.  The obligation of each Lender to so reimburse Issuing Lender shall be
absolute and unconditional and shall not be affected by the occurrence of a Default or Event of Default or any other occurrence or event.  Any such reimbursement shall not relieve or otherwise impair the obligation of Borrower to reimburse Issuing Lender for the
amount of any payment made by Issuing Lender under any Letter of Credit, together with interest as provided herein.

(f)   Nature of Lenders’ Funding.  If the conditions precedent set forth in Section 4.02 can be satisfied (except for the giving of a Request for Extension of Credit) on any date Borrower is obligated to, but fails to, reimburse
Issuing Lender for a drawing under a Letter of Credit, the funding by Lenders pursuant to the previous subsection shall be deemed to be a Borrowing of Base Rate Loans (without regard to the Minimum Amount therefor) deemed requested by Borrower.  If the
conditions precedent set forth in Section 4.02 cannot be satisfied on the date Borrower is obligated to, but fails to, reimburse Issuing Lender for a drawing under a Letter of Credit, the funding by Lenders pursuant to the previous subsection shall be deemed to be a
funding by each Lender of its risk participation in such Letter of Credit, and each Lender making such funding shall thereupon acquire a pro rata participation, to the extent of its reimbursement, in the claim of Issuing Lender against Borrower in respect of such
payment and shall share, in accordance with that pro rata participation, in any payment made by Borrower with respect to such claim.  Any amounts made available by a Lender under its risk participation shall be payable by Borrower upon demand of Administrative
Agent, and shall bear interest at a rate per annum equal to the Default Rate.

(g)   Special Provisions Relating to Evergreen Letters of Credit.  Upon request by Borrower, Issuing Lender in its sole and absolute discretion may issue Letters of Credit that have automatic extension or renewal provisions
(“evergreen” Letters of Credit).  Issuing Lender shall have the right under any such evergreen Letters of Credit to not permit any such extension or renewal at least annually within a notice period to be agreed upon at the time each such Letter of
Credit is issued.  Once an evergreen Letter of Credit is issued, unless Administrative Agent has notified Issuing Lender that Requisite Lenders have elected not to permit such extension or renewal, the Borrower Parties, Administrative Agent and Lenders shall be
deemed to have authorized (but may not require) Issuing Lender to, in its sole and absolute discretion, permit the renewal of such evergreen Letter of Credit at any time to a date not later than the Letter of Credit Expiration Date, and, unless directed by Issuing
Lender, Borrower shall not be required to request such extension or renewal.  Issuing Lender may in its sole and absolute discretion elect not to permit an evergreen Letter of Credit to be extended or renewed at any time.

(h)   Obligations Absolute.  The obligation of Borrower to pay to Issuing Lender the amount of any payment made by Issuing Lender under any Letter of Credit shall be absolute, unconditional, and irrevocable.  Without limiting the
foregoing, Borrower’s obligation shall not be affected by any of the following circumstances:

      (i)      any lack of validity or enforceability of such Letter of Credit, this Agreement, or any other agreement or instrument relating thereto;

28

      (ii)     any amendment or waiver of or any consent to departure from such Letter of Credit, this Agreement, or any other agreement or instrument relating hereto or thereto;

      (iii)    the existence of any claim, setoff, defense, or other rights which Borrower may have at any time against Issuing Lender, Administrative Agent or any Lender, any beneficiary of such Letter of Credit (or
any persons or entities for whom any such beneficiary may be acting) or any other Person, whether in connection with such Letter of Credit, this Agreement, or any other agreement or instrument relating thereto, or any unrelated transactions;

      (iv)    any demand, statement, or any other document presented under such Letter of Credit proving to be forged, fraudulent, invalid, or insufficient in any respect or any statement therein being untrue or
inaccurate in any respect whatsoever so long as any such document appeared to comply with the terms of the Letter of Credit;

      (v)     any payment made by Issuing Lender under such Letter of Credit to any Person purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit of creditors, liquidator, receiver
or other representative of or successor to any beneficiary or any transferee of such Letter of Credit, including any arising in connection with any proceeding under any Debtor Relief Laws;

      (vi)    the existence, character, quality, quantity, condition, packing, value or delivery of any property purported to be represented by documents presented in connection with such Letter of Credit or for any
difference between any such property and the character, quality, quantity, condition, or value of such property as described in such documents;

      (vii)   the time, place, manner, order or contents of shipments or deliveries of property as described in documents presented in connection with such Letter of Credit or the existence, nature and extent of any
insurance relative thereto;

      (viii)  the solvency or financial responsibility of any party issuing any documents in connection with such Letter of Credit;

      (ix)    any failure or delay in notice of shipments or arrival of any property;

      (x)     any error in the transmission of any message relating to such Letter of Credit not caused by Issuing Lender, or any delay or interruption in any such message;

      (xi)    any error, neglect or default of any correspondent of Issuing Lender in connection with such Letter of Credit;

      (xii)   any consequence arising from acts of God, wars, insurrections, civil unrest, disturbances, labor disputes, emergency conditions or other causes beyond the control of Issuing Lender;

      (xiii)  so long as Issuing Lender in good faith determines that the document appears to comply with the terms of the Letter of Credit, the form, accuracy, genuineness or legal effect of any contract or document referred to
in any document submitted to Issuing Lender in connection with such Letter of Credit; and

29

      (xiv)  any other circumstances whatsoever where Issuing Lender has acted in good faith.

In addition, Borrower will promptly examine a copy of each Letter of Credit and amendments thereto delivered to it and, in the event of any claim of noncompliance with Borrower’s instructions or other irregularity, Borrower will immediately notify Issuing
Lender in writing.  Borrower shall be conclusively deemed to have waived any such claim against Issuing Lender and its correspondents unless such notice is given as aforesaid.

(i)   Role of Issuing Lender.  Each Lender and Borrower agree that, in paying any drawing under a Letter of Credit, Issuing Lender shall not have any responsibility to obtain any document (other than any sight draft, certificates and
documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the authority of the Person executing or delivering any such document.  No Administrative Agent-Related Person nor any of the
respective correspondents, participants or assignees of Issuing Lender shall be liable to any Lender for any action taken or omitted in connection herewith at the request or with the approval of Lenders or Requisite Lenders, as applicable; any action taken or omitted
in the absence of gross negligence or willful misconduct; or the due execution, effectiveness, validity or enforceability of any document or instrument related to any Letter of Credit.  Borrower hereby assumes all risks of the acts or omissions of any
beneficiary or transferee with respect to its use of any Letter of Credit; provided, however, that this assumption is not intended to, and shall not, preclude Borrower’s pursuing such rights and remedies as it may have against the beneficiary or transferee at
law or under any other agreement.  No Administrative Agent-Related Person, nor any of the respective correspondents, participants or assignees of Issuing Lender, shall be liable or responsible for any of the matters described in subsection (g) above.  In
furtherance and not in limitation of the foregoing, Issuing Lender may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and Issuing Lender shall not
be responsible for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or
ineffective for any reason.

(j)   Applicability of ISP98 and UCP.  Unless otherwise expressly agreed by Issuing Lender and Borrower when a Letter of Credit is issued and subject to applicable laws, performance under Letters of Credit by Issuing Lender, its
correspondents, and beneficiaries will be governed by, with respect to standby Letters of Credit, the rules of the “International Standby Practices 1998” (ISP98) or such later revision as may be published by the International Chamber of Commerce (the
“ICC”).

(k)   Letter of Credit Fee.  On each Applicable Payment Date, Borrower shall pay to Administrative Agent in arrears, for the account of each Lender in accordance with its Pro Rata Share, a Letter of Credit fee equal to the Applicable
Amount for Offshore Rate Loans on a per annum basis times the actual daily maximum amount available to be drawn under each Letter of Credit for the period since the later of the Closing Date and the previous Applicable Payment Date.  If there is any change in
the Applicable Amount during any quarter, the actual daily amount shall be computed and multiplied by the Applicable Amount separately for each period during such quarter that such Applicable Amount was in effect.

30

(l)   Fronting Fee and Documentary and Processing Charges Payable to Issuing Lender.  On each Applicable Payment Date, Borrower shall pay to Administrative Agent for the sole account of Issuing Lender a fronting fee in an amount equal to
0.125% per annum on the daily average face amount of all outstanding Letters of Credit, payable in arrears.  In addition, Borrower shall pay directly to Issuing Lender, upon demand, for its sole account its customary documentary and processing charges in
accordance with its standard schedule, as from time to time in effect, for any Letter of Credit Action or other occurrence relating to a Letter of Credit for which such charges are customarily made.  Such fees and charges are nonrefundable.

2.04    Prepayments.

(a)   Upon Requisite Notice to Administrative Agent not later than the Requisite Time therefor, Borrower may at any time and from time to time voluntarily prepay Loans in part in the Minimum Amount therefor or in full without premium or
penalty.  Administrative Agent will promptly notify each Lender thereof and of such Lender’s Pro Rata Share of such prepayment.  Any prepayment of an Offshore Rate Loan shall be accompanied by all accrued interest thereon, together with the amounts
set forth in Section 3.05.

(b)   If for any reason the Outstanding Obligations exceed the combined Commitments as in effect or as reduced because of any limitation set forth in this Agreement or otherwise, Borrower shall immediately prepay Loans in an aggregate amount equal
to such excess.

2.05   Reduction or Termination of Commitments.  Upon Requisite Notice to Administrative Agent not later than the Requisite Time therefor, Borrower may at any time and from time to time, permanently and irrevocably reduce the Commitments
in a Minimum Amount therefor to an amount not less than the Outstanding Obligations at such time or terminate the Commitments.  Any such reduction or termination shall be accompanied by payment to the Administrative Agent of all accrued and unpaid commitment
fees with respect to the portion of the Commitments being reduced or terminated.  Administrative Agent shall promptly notify Lenders of any such request for reduction or termination of the Commitments.  In the event of a reduction of Commitments in
accordance with this Section 2.05, each Lender’s Commitment shall be reduced by an amount equal to such Lender’s Pro Rata Share times the amount of such reduction.

2.06    Principal and Interest.

(a)   Except as otherwise provided hereunder, if not sooner paid, Borrower agrees to pay the outstanding principal amount of each Loan on the Maturity Date.

(b)   Subject to subsection (c) below, and unless otherwise specified herein, Borrower shall pay interest on the unpaid principal amount of each Loan (before and after default, before and after maturity, before and after judgment, and before and
after the commencement of any proceeding under any Debtor Relief Laws) from the date borrowed until paid in full (whether by acceleration or otherwise) on each Applicable Payment Date at a rate per annum equal to the interest rate determined in accordance with the
definition of such type of Loan, plus the applicable margin specified in the definition in this Agreement of Applicable Amount with respect to such type of Loan.

31

(c)   Notwithstanding subsection (b) of this Section, while any Event of Default exists or after acceleration, Borrower shall pay interest (after as well as before entry of judgment thereon to the extent permitted by law) on the principal amount of
all outstanding Obligations, at the Default Rate.

2.07    Fees.

(a)   Facility Fee.  Borrower shall pay to Administrative Agent (for the account of each Lender according to its Pro Rata Share) the respective facility fee set forth in the definition in this Agreement of Applicable Amount, calculated
on the full amount of the combined Commitments.  The facility fee shall accrue from the Closing Date until the Maturity Date and shall be calculated and payable quarterly in arrears on each Applicable Payment Date.  The facility fee shall accrue at all
times, including at any time during which one or more conditions in Section 4 are not met.

(b)   Agency and Arrangement Fees.  Borrower shall pay to Administrative Agent an administrative agency fee and a structuring and arrangement fee, respectively, in such amounts and at such times as set forth in a separate letter
agreement dated October 26, 2005, among Borrower and Administrative Agent (the "Fee Letter").  Such fees are for the services to be performed by Administrative Agent in acting as Administrative Agent and Lead Arranger in structuring and arranging the
credit facilities under this Agreement and are fully earned on the date paid.  Such fees are solely for Administrative Agent’s own account and are nonrefundable.

(c)   Lenders’ Upfront Fee.  On the Closing Date, Borrower shall pay to Administrative Agent for the account of each Lender an upfront fee in an amount agreed between Administrative Agent and Borrower, calculated based on each
Lender’s Commitment and allocated by Administrative Agent.  Such upfront fees are consideration for the Commitments by each Lender under this Agreement and are fully earned on the date paid.  The upfront fee paid to each Lender is solely for its own
account and is nonrefundable.

2.08    Computation of Interest and Fees.  Computation of interest on Base Rate Loans when the Base Rate is determined by KeyBank’s “prime rate” shall be calculated on the basis of a year of 365 or 366 days, as the case
may be, and the actual number of days elapsed.  Computation of all other types of interest and all fees shall be calculated on the basis of a year of 360 days and the actual number of days elapsed, which results in a higher yield to Lenders than a method based
on a year of 365 or 366 days.  Interest shall accrue on each Loan for the day on which the Loan is made, and shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is paid, provided that any Loan that is repaid on the
same day on which it is made shall bear interest for one day.

2.09    Making Payments.

(a)   Except as otherwise provided herein, all payments by Borrower or any Lender hereunder shall be made to Administrative Agent at Administrative Agent’s Office not later than the Requisite Time for such type of payment.  All payments
received after such Requisite Time shall be deemed received on the next succeeding Business Day.  All payments shall be made in immediately available funds in lawful money of the United States of America.  All payments by

32

Borrower shall be made without condition or deduction for any counterclaim, defense, recoupment or setoff.

(b)   Upon satisfaction of any applicable terms and conditions set forth herein, Administrative Agent shall promptly make any amounts received in accordance with the prior subsection available in like funds as received, as follows:  (i) if
payable to Borrower, by crediting the Designated Deposit Account, and (ii) if payable to any Lender, by wire transfer to such Lender at its Lending Office.  In the case of amounts held by Administrative Agent that are payable to Borrower, if any applicable terms
and conditions are not so satisfied, Administrative Agent shall return any funds it is holding that would otherwise be payable to Borrower to the Lenders making such funds available, without interest.

(c)   Subject to the definition of “Interest Period,” if any payment to be made by Borrower shall come due on a day other than a Business Day, payment shall instead be considered due on the next succeeding Business Day, and such
extension of time shall be reflected in computing interest and fees.

(d)   Unless Borrower or any Lender has notified Administrative Agent prior to the date any payment to be made by it is due, that it does not intend to remit such payment, Administrative Agent may, in its sole and absolute discretion, assume that
Borrower or Lender, as the case may be, has timely remitted such payment and may, in its sole and absolute discretion and in reliance thereon, make available such payment to the Person entitled thereto.   If such payment was not in fact remitted to
Administrative Agent in immediately available funds, then:

      (i)     if Borrower failed to make such payment, each Lender shall forthwith on demand repay to Administrative Agent the amount of such assumed payment made available to such Lender, together with interest
thereon in respect of each day from and including the date such amount was made available by Administrative Agent to such Lender to the date such amount is repaid to Administrative Agent at the Federal Funds Rate; and

      (ii)     if any Lender failed to make such payment, Administrative Agent shall be entitled to recover such corresponding amount on demand from such Lender.  If such Lender does not pay such corresponding
amount forthwith upon Administrative Agent’s demand therefor, Administrative Agent promptly shall notify Borrower, and Borrower shall pay such corresponding amount to Administrative Agent.  Administrative Agent also shall be entitled to recover from such
Lender interest on such corresponding amount in respect of each day from the date such corresponding amount was made available by Administrative Agent to Borrower to the date such corresponding amount is recovered by Administrative Agent, (A) from such Lender at a
rate per annum equal to the daily Federal Funds Rate, and (B) from Borrower, at a rate per annum equal to the interest rate applicable to such Borrowing.  Nothing herein shall be deemed to relieve any Lender from its obligation to fulfill its Commitment or to
prejudice any rights which Administrative Agent or Borrower may have against any Lender as a result of any default by such Lender hereunder.

(e)   If Administrative Agent or any Lender is required at any time to return to Borrower, or to a trustee, receiver, liquidator, custodian, or any official under any proceeding under Debtor Relief Laws, any portion of a payments made by Borrower,
each Lender shall, on

33

demand of Administrative Agent, return its share of the amount to be returned, plus interest thereon from the date of such demand to the date such payment is made at a rate per annum equal to the daily Federal Funds Rate.

2.10    Funding Sources.  Nothing in this Agreement shall be deemed to obligate any Lender to obtain the funds for any Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will
obtain the funds for any Loan in any particular place or manner.

2.11    Supplemental Borrowing Account. Borrower shall establish a Supplemental Borrowing Account with Administrative Agent, and Borrower shall deposit into said account such funds (if any) as may required so that the Availability Limit shall
at all times equal or exceed the total Outstanding Obligations under this Agreement.  Administrative Agent, on behalf of itself and all other Lenders, shall have a security interest in the Supplemental Borrowing Account to secure the Outstanding Obligations
under this Agreement.  Borrower may withdraw funds from the Supplemental Borrowing Account only if, and to the extent that, the Availability Limit exceeds the total Outstanding Obligations under this Agreement.

2.12    Collateral.  Borrower's Obligations are secured by the Deed of Trust, the General Security Agreement, the Intellectual Property Security Agreement, the Stock Pledge Agreement, the Deposit Account Control Agreements and the
Securities Account Control Agreements.

SECTION 3

TAXES, YIELD PROTECTION AND ILLEGALITY

3.01    Taxes.

(a)   Any and all payments by Borrower to or for the account of Administrative Agent or any Lender under any Loan Document shall be made free and clear of and without deduction for any and all present or future taxes, duties, levies, imposts,
deductions, assessments, fees, withholdings or similar charges, and all liabilities with respect thereto, excluding, in the case of Administrative Agent and each Lender, (i) taxes imposed on or measured by its net income, (ii) franchise taxes imposed on it (in lieu
of net income taxes) by the jurisdiction (or any political subdivision thereof) under the Laws of which Administrative Agent or such Lender, as the case may be, is organized or maintains a lending office; (iii) any applicable withholding tax imposed by Sections 1441
and 1442 of the Code that is withheld by Administrative Agent from a payment to any Foreign Lender (as defined in Section 10.21 of this Agreement) pursuant to Section 10.21; and (iv) any penalties, interest, costs and expenses (including Attorney Costs) imposed on
Administrative Agent or any Lender arising from the assertion by any Governmental Authority that Administrative Agent did not properly withhold any tax or other amount from payments made in respect of any Foreign Lender (all such non-excluded taxes, duties, levies,
imposts, deductions, assessments, fees, withholdings or similar charges, and liabilities being hereinafter referred to as “Taxes”).  If Borrower shall be required by any Laws to deduct any Taxes from or in respect of any sum payable under any
Loan Document to Administrative Agent or any Lender, (A) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section), Administrative Agent and such Lender
receives an amount equal to the sum it would have received had no such

34

deductions been made, (B) Borrower shall make such deductions, (C) Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable Laws, and (D) within 30 days after the date of such payment, Borrower
shall furnish to Administrative Agent (who shall forward the same to such Lender) the original or a certified copy of a receipt evidencing payment thereof.

(b)   In addition, Borrower agrees to pay any and all present or future stamp, court or documentary taxes and any other excise or property taxes or charges or similar levies which arise from any payment made under any Loan Document or from the
execution, delivery, performance, enforcement or registration of, or otherwise with respect to, any Loan Document (hereinafter referred to as “Other Taxes”).

(c)   If Borrower shall be required by the Laws of any jurisdiction outside the United States to deduct any Taxes from or in respect of any sum payable under any Loan Document to Administrative Agent or any Lender, Borrower shall also pay to such
Lender or Administrative Agent (for the account of such Lender), at the time interest is paid, such additional amount that the respective Lender specifies as necessary to preserve the after-tax yield (after factoring in United States (federal and state) taxes imposed
on or measured by net income) such Lender would have received if such deductions (including deductions applicable to additional sums payable under this Section) had not been made.

(d)   Borrower agrees to indemnify, defend and hold Administrative Agent and each Lender harmless for (i) the full amount of Taxes and Other Taxes (including any Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under
this Section) paid by Administrative Agent and such Lender; (ii) any liability (including penalties, interest and expenses) arising therefrom or with respect thereto; and (iii) amounts payable under Section 3.01(c); provided that (A) Borrower shall not be
obligated to indemnify the Administrative Agent or any Lender for any penalties described in clause (ii) above to the extent the Administrative Agent or such Lender (1) had actual knowledge of the existence of the tax, interest, or expense, the non-payment of which
gave rise to such penalties, and (2) failed to give the Borrower notice of such tax, interest or expense within ten Business Days after the Administrative Agent or such Lender received actual knowledge of the existence thereof; and (B) nothing contained in this
subsection (d) shall be deemed to imply any obligation on the part of the Administrative Agent or any Lender to provide the Borrower with the notice of any such tax, penalty, interest or expense.  Payment under this subsection (d) shall be made within 30 days
after the date the Lender or the Administrative Agent makes a demand therefor. 

3.02    Illegality.  If any Lender determines that any Laws have made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to make, maintain or fund Offshore
Rate Loans, or materially restricts the authority of such Lender to purchase or sell, or to take deposits of, Dollars in the applicable offshore Dollar market, or to determine or charge interest rates based upon the Offshore Rate, then, on notice thereof by Lender to
Borrower through Administrative Agent, any obligation of such Lender to make Offshore Rate Loans shall be suspended until Lender notifies Administrative Agent and Borrower that the circumstances giving rise to such determination no longer exist.  Upon receipt of
such notice, Borrower shall, upon demand from such Lender (with a copy to Administrative Agent), prepay or Convert all Offshore Rate Loans of such Lender,

35

either on the last day of the Interest Period thereof, if Lender may lawfully continue to maintain such Offshore Rate Loans to such day, or immediately, if Lender may not lawfully continue to maintain such Offshore Rate Loans.  Each Lender agrees to designate
a different Lending Office if such designation will avoid the need for such notice and will not, in the good faith judgment of such Lender, otherwise be materially disadvantageous to such Lender.

3.03    Inability to Determine Rates.  If, in connection with any Request for Extension of Credit involving any Offshore Rate Loan, Administrative Agent determines that (a) Dollar deposits are not being offered to banks in the applicable
offshore dollar market for the applicable amount and Interest Period of the requested Offshore Rate Loan, (b) adequate and reasonable means do not exist for determining the underlying interest rate for such Offshore Rate Loan, or (c) such underlying interest rate
does not adequately and fairly reflect the cost to Lender of funding such Offshore Rate Loan, Administrative Agent will promptly notify Borrower and all Lenders.  Thereafter, the obligation of all Lenders to make or maintain such Offshore Rate Loan shall be
suspended until Administrative Agent revokes such notice.  Upon receipt of such notice, Borrower may revoke any pending request for a Borrowing of Offshore Rate Loans or, failing that, be deemed to have converted such request into a request for a Borrowing of
Base Rate Loans in the amount specified therein.

3.04    Increased Cost and Reduced Return; Capital Adequacy.

(a)   If any Lender determines that any Laws:

      (i)     impose on such Lender any Tax, duty, or other charge with respect to any Offshore Rate Loans or its obligation to make Offshore Rate Loans;

      (ii)    change the basis on which Taxes are imposed on any amounts payable to such Lender under this Agreement in respect of any Offshore Rate Loans;

      (iii)   impose or modify any reserve, special deposit, or similar requirement (other than the reserve requirement utilized in the determination of the Offshore Rate) relating to any extensions of credit or other assets
of, or any deposits with or other liabilities or commitments of, such Lender (including its Commitment); or

      (iv)   impose on such Lender or on the offshore Dollar interbank market any other condition affecting this Agreement or any of such extensions of credit or liabilities or commitments;

and the result of any of the foregoing is to increase the cost to such Lender of making, Converting into, Continuing, or maintaining any Offshore Rate Loans or to reduce any sum received or receivable by such Lender under this Agreement with respect to any
Offshore Rate Loans, then from time to time upon demand of Lender (with a copy of such demand to Administrative Agent), Borrower shall pay to such Lender such additional amounts as will compensate such Lender for such increased cost or reduction (except to the extent
that such increased cost or reduction is an amount subject to Section 3.01, in which case the sum received or receivable by such Lender shall be increased in accordance with the provisions of Section 3.01).

36

(b)   If any Lender determines that any change in or the interpretation of any Laws have the effect of reducing the rate of return on the capital of such Lender or compliance by such Lender (or its Lending Office) or any corporation controlling such
Lender as a consequence of such Lender’s obligations hereunder (taking into consideration its policies with respect to capital adequacy and such Lender’s desired return on capital), then from time to time upon demand of such Lender (with a copy to
Administrative Agent), Borrower shall pay to such Lender such additional amounts as will compensate such Lender for such reduction; provided, however, that Borrower shall not be required to pay additional amounts to compensate any Lender for (i) any applicable
withholding tax imposed by Sections 1441 and 1442 of the Code that is withheld by Administrative Agent from a payment to any Foreign Lender pursuant to Section 10.21, (ii) any reduction in connection with any penalties, interest, costs and expenses (including
Attorney Costs) arising from the assertion by any Governmental Authority that Administrative Agent did not properly withhold any tax or other amount from payments made in respect of any Foreign Lender; or (iii) any change in the rate of applicable taxes imposed on or
measured by net income.

3.05    Breakfunding Costs.  Upon demand of any Lender (with a copy to Administrative Agent) from time to time, Borrower shall promptly compensate such Lender for and hold such Lender harmless from any loss, cost or expense incurred by
it as a result of:

(a)   any Continuation, Conversion, payment or prepayment of any Loan other than a Base Rate Loan on a day other than the last day of the Interest Period for such Loan (whether voluntary, mandatory, automatic, by reason of acceleration, or
otherwise); or

(b)   any failure by Borrower (for a reason other than the failure of such Lender to make a Loan) to prepay, borrow, Continue or Convert any Loan other than a Base Rate Loan on the date or in the amount notified by Borrower;

including any loss of anticipated profits and any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such Loan or from fees payable to terminate the deposits from which such funds were obtained.  Borrower shall
also pay any customary administrative fees charged by such Lender in connection with the foregoing.

3.06    Matters Applicable to all Requests for Compensation.

(a)   The Administrative Agent or any Lender claiming compensation under this Section 3 shall deliver to Borrower a certificate setting forth in reasonable detail the additional amount or amounts to be paid to it hereunder, which shall be conclusive
in the absence of clearly demonstrable error.  In determining such amount, Lenders may use any reasonable averaging and attribution methods.  For purposes of this Section 3, a Lender shall be deemed to have funded each Offshore Rate Loan at the Offshore
Rate for such Loan by a matching deposit or other borrowing in the offshore Dollar interbank market, whether or not such Offshore Rate Loan was in fact so funded.

(b)   Borrower shall not be obligated to pay any amount under this Section 3 which arose prior to the date which is 180 days preceding the date of such demand or is attributable to periods prior to the date which is 180 days preceding the date of
such demand; provided, however, that in the event any Law is enacted that retroactively imposes any cost or charge upon

37

the Administrative Agent or any Lender that would otherwise be a basis for compensation under Sections 3.01 through 3.05, the Administrative Agent or such Lender may make a demand for such compensation through and including the date which is 180 days after the
date upon which such Law takes effect.

(c)   Upon any Lender making a claim for compensation under Section 3.01 or 3.04, Borrower may remove and replace such Lender in accordance with Section 10.22.

3.07    Survival.  All of Borrower’s obligations under this Section 3 shall survive for a period of one year after the later of termination of the Commitments, and payment in full of all Obligations; provided,
however, that the obligation of Borrower to make any payment under this Section 3 is contingent upon the receipt by Borrower of the certificate described in Section 3.06(a) within the later of (a) 180 days after the later of the repayment of all Loans, the
termination of all Letters of Credit and the termination of the Commitment, or (b) in the case of any Law retroactively imposing any cost or charge upon the Administrative Agent or any Lender, 180 days after the date upon which such Law takes effect.

threatened by or against Borrower or any of its Subsidiaries or against any of their properties or revenues which could reasonably be expected to have a Material Adverse Effect.

5.06    No Default.  Neither Borrower nor any its Subsidiaries are in default under or with respect to any Contractual Obligation which could reasonably be expected to have a Material Adverse Effect, and no Default or Event of Default

that in each case no material item or portion of property of Borrower or any of its Subsidiaries is in jeopardy of being seized, levied upon or forfeited.

5.09    Margin Regulations; Investment Company Act; Public Utility Holding Company Act.

(a)   Borrower is not engaged nor will it engage, principally or as one of its important activities, in the business of extending credit for the purpose of “purchasing” or “carrying” “margin stock” within the
respective meanings of each of the quoted terms under Regulation U of the Board of Governors of the Federal Reserve System as now and from time to time hereafter in effect.  No part of the proceeds of any Extensions of Credit hereunder will be used for
“purchasing” or “carrying” “margin stock” as so defined or for any purpose which violates, or which would be inconsistent with, the provisions of Regulations U or X of such Board of Governors.

(b)    Neither Borrower nor any of its Subsidiaries (i) is a “holding company,” or a “subsidiary company” of a “holding company,” or an “affiliate” of a “holding company” or of a

giving of notice under Section 4219 of ERISA, would result in such liability) under Sections 4201 or 4243 of ERISA with respect to a Multiemployer Plan; and (v) neither Borrower nor any ERISA Affiliate has engaged in a transaction that could be subject to Sections
4069 or 4212(c) of ERISA.

42

conduct of their respective businesses as now operated or could obtain such right without causing a Material Adverse Effect, and none of such items, to the best knowledge of Borrower, conflicts with the valid trademark, trade name, copyright, patent, patent right or
intangible asset of any other Person to the extent that such conflict has or could reasonably be expected to have a Material Adverse Effect.

5.12    Compliance With Laws.  Borrower and its Subsidiaries are in compliance in all material respects with all material Laws that are applicable such Person.

5.13    Environmental Compliance.  Borrower and its Subsidiaries conduct in the ordinary course of business a review of the effect of existing Environmental Laws and claims alleging potential liability or responsibility for violation of
any Environmental Law on their respective businesses, operations and properties, and as a result thereof Borrower has reasonably concluded that such Environmental Laws and claims do not, individually or in the aggregate, have a Material Adverse Effect.

5.14    Insurance.  The properties of Borrower and its Subsidiaries are insured with financially sound and reputable insurance companies not Affiliates of Borrower, in such amounts, with such deductibles and covering such risks as are
customarily carried by companies engaged in similar businesses and owning similar properties in localities where Borrower or such Subsidiary operates.

5.15    Swap Obligations.  Neither Borrower nor any of its Subsidiaries has incurred any outstanding obligations under any Swap Contracts, other than Permitted Swap Obligations.  Borrower has undertaken its own independent
assessment of its consolidated assets, liabilities and commitments and has considered appropriate means of mitigating and managing risks associated with such matters and has not relied on any swap counterparty or any Affiliate of any swap counterparty in determining
whether to enter into any Swap Contract.

5.16    Disclosure.  No statement, information, report, representation, or warranty made by Borrower in any Loan Document or furnished to Administrative Agent or any Lender in connection with any Loan Document contains any untrue
statement of a material fact or, when viewed together with Borrower’s periodic reports filed under the Exchange Act and the rules and regulations promulgated thereunder, omits to state any material fact necessary to make the statements herein or therein not
misleading.

SECTION 6

45

financial trade secrets or non-financial proprietary information, or (ii) the disclosure of which to any Lender, or their designated representative, is then prohibited by law or any agreement binding on Borrower or any of its Subsidiaries that was not entered into

and Lenders than those set forth on Schedule 7.13, (iii) increase the interest rate applicable thereto, or (iv) accelerate the scheduled payment thereof.  Borrower shall not cause or permit any of its obligations, except the obligations constituting Senior
Indebtedness, to constitute "Designated Senior Indebtedness" under the Indenture governing the New Convertible Subordinated Notes (it being understood that the Obligations of Borrower under this Agreement shall at all times constitute "Designated Senior Indebtedness"
under such indenture).  Notwithstanding the foregoing, Borrower may at any time:

of such Subordinated Debt in connection with such a conversion but solely to the extent representing the value of any fractional shares; (C) make payments of interest on such Subordinated Debt not in violation of the Subordination provisions of such Subordinated
Debt; (D) pay additional interest in an amount not to exceed 50 basis points per annum of the aggregate principal amount of the New Convertible Subordinated Notes to the extent due under the provisions of the New

54

Convertible Subordinated Notes due to Borrower's failure to register such notes or shares of common stock into which the notes are convertible within the period or to keep such notes or shares registered for or during the periods specified in the indenture for the
New Convertible Subordinated Notes or the Registration Rights Agreement; and (E) make other payments, repayments, redemptions, purchases, defeasance or other satisfaction of Subordinated Debt not to exceed $5,000,000 in the aggregate.

deposited in domestic accounts subject to the Deposit Account Control Agreements and Securities Account Control Agreements.  This covenant shall apply at all times and shall be tested monthly in accordance with such reports.

(k)    (i) An ERISA Event occurs with respect to a Pension Plan or Multiemployer Plan which has resulted or could reasonably be expected to result in liability of Borrower under Title IV of ERISA to the Pension Plan, Multiemployer Plan or the PBGC
in an aggregate amount in excess of the Threshold Amount; (ii) the aggregate amount of Unfunded Pension Liability among all Pension Plans at any time exceeds the Threshold Amount; or (iii) Borrower or any ERISA Affiliate fails to pay when due, after the expiration of
any applicable grace period, any installment payment with respect to its withdrawal liability under Section 4201 of ERISA under a Multiemployer Plan in an aggregate amount in excess of the Threshold Amount; or

(l)   There occurs (i) any Change of Control, or (ii) any event relating to a change in the corporate ownership, control or governance of Borrower or any Subsidiary as issuer (“Issuer”) of any notes, bonds, debentures, Subordinated Debt
or other debt securities, the result of which is to cause Indebtedness evidenced by any such notes, bonds, debentures, Subordinated Debt or other debt securities to be subject to mandatory redemption or repurchase by Issuer, provided the outstanding amount of such
outstanding Indebtedness exceeds the Threshold Amount.

8.02    Certain Financial Covenant Defaults.  In the event that, after taking into account any extraordinary charge to earnings taken or to be taken as of the end of any fiscal period of Borrower (a “Charge”), and if
solely by virtue of such Charge, there would exist an Event of Default due to breach of Section 7.12 as of such fiscal period end date, such Event of Default shall be deemed to arise upon the earlier of (i) the date after such fiscal period end date

57

on which Borrower announces publicly it will take, is taking or has taken such Charge (including an announcement in the form of a statement in a report filed with the SEC) or, if such announcement is made prior to such fiscal period end date, the date that is such
fiscal period end date, and (ii) the date Borrower delivers to Administrative Agent its audited annual or unaudited quarterly financial statements in respect of such fiscal period reflecting such Charge as taken.

8.03    Remedies Upon Event of Default.  Without limiting any other rights or remedies of Administrative Agent or Lenders provided for elsewhere in this Agreement, or the other Loan Documents, or by applicable Law, or in equity, or
otherwise:

(a)   Upon the occurrence, and during the continuance, of any Event of Default other than an Event of Default described in Section 8.01(j):

      (i)     Requisite Lenders may request Administrative Agent to, and Administrative Agent thereupon shall, terminate the Commitments and/or declare all or any part of the unpaid principal of all Loans, all
interest accrued and unpaid thereon and all other amounts payable under the Loan Documents to be immediately due and payable, whereupon the same shall become and be immediately due and payable, without protest, presentment, notice of dishonor, demand or further
notice of any kind, all of which are expressly waived by Borrower; and/or

      (ii)    Issuing Lender may, with the approval of Administrative Agent on behalf of Requisite Lenders, demand immediate payment by Borrower of an amount equal to the aggregate amount of all outstanding Letter of
Credit Usage to be held in a Letter of Credit Cash Collateral Account.

(b)   Upon the occurrence of any Event of Default described in Section 8.01(j):

      (i)     the Commitments and all other obligations of Administrative Agent or Lenders shall automatically terminate without notice to or demand upon Borrower, which are expressly waived by Borrower;

      (ii)    the unpaid principal of all Loans, all interest accrued and unpaid thereon and all other amounts payable under the Loan Documents shall be immediately due and payable, without protest, presentment, notice
of dishonor, demand or further notice of any kind, all of which are expressly waived by Borrower; and

      (iii)   an amount equal to the aggregate amount of all outstanding Letter of Credit Usage shall be immediately due and payable to Issuing Lender without notice to or demand upon Borrower, which are expressly waived by
Borrower, to be held in a Letter of Credit Cash Collateral Account.

(c)   Upon the occurrence of any Event of Default, Lenders and Administrative Agent, or any of them, without notice to (except as expressly provided for in any Loan Document) or demand upon Borrower, which are expressly waived by Borrower (except as
to notices expressly provided for in any Loan Document), may proceed to (but only with the consent of Requisite Lenders) protect, exercise and enforce their rights and remedies under the Loan Documents

58

against Borrower and such other rights and remedies as are provided by Law or equity (including, without limitation, the provisions of the applicable Uniform Commercial Code).

(d)   Except as permitted by Section 10.05, no Lender may exercise any rights or remedies with respect to the Obligations without the consent of Requisite Lenders in their sole and absolute discretion.  The order and manner in which
Administrative Agent’s and Lenders’ rights and remedies are to be exercised shall be determined by Requisite Lenders in their sole and absolute discretion.  Regardless of how a Lender may treat payments for the purpose of its own accounting, for the
purpose of computing the Obligations hereunder, payments shall be applied first, to costs and expenses (including Attorney Costs) incurred by Administrative Agent and each Lender, second, to the payment of accrued and unpaid interest on the Loans to and including the
date of such application, third, to the payment of the unpaid principal of the Loans, and fourth, to the payment of all other amounts (including fees) then owing to Administrative Agent and Lenders under the Loan Documents, in each case paid pro rata to each Lender
in the same proportions that the aggregate Obligations owed to each Lender under the Loan Documents bear to the aggregate Obligations owed under the Loan Documents to all Lenders, without priority or preference among Lenders.  No application of payments will
cure any Event of Default, or prevent acceleration, or continued acceleration, of amounts payable under the Loan Documents, or prevent the exercise, or continued exercise, of rights or remedies of Administrative Agent and Lenders hereunder or thereunder or at Law or
in equity.

SECTION 9

ADMINISTRATIVE AGENT

9.01    Appointment and Authorization of Administrative Agent.

(a)   Each Lender hereby irrevocably (subject to Section 9.09) appoints, designates and authorizes Administrative Agent to take such action on its behalf under the provisions of this Agreement and each other Loan Document and to exercise such powers
and perform such duties as are expressly delegated to it by the terms of this Agreement or any other Loan Document, together with such powers as are reasonably incidental thereto.  Notwithstanding any provision to the contrary contained elsewhere in this
Agreement or in any other Loan Document, Administrative Agent shall not have any duties or responsibilities, except those expressly set forth herein, nor shall Administrative Agent have or be deemed to have any fiduciary relationship with any Lender, and no implied
covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against Administrative Agent.  Without limiting the generality of the foregoing sentence, the use of the
term “agent” in this Agreement with reference to Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law.  Instead, such term is used merely as a
matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.

(b)   Issuing Lender shall act on behalf of Lenders with respect to any Letters of Credit issued by it and the documents associated therewith until such time and except for so long as Administrative Agent may agree at the request of Requisite
Lenders to act for such Issuing Lender with respect thereto; provided, however, that Issuing Lender shall have all of the benefits

59

and immunities (i) provided to Administrative Agent in this Section 9 with respect to any acts taken or omissions suffered by Issuing Lender in connection with Letters of Credit issued by it or proposed to be issued by it and the application and agreements for
letters of credit pertaining to the Letters of Credit as fully as if the term “Administrative Agent” as used in this Section 9 included Issuing Lender with respect to such acts or omissions, and (ii) as additionally provided in this Agreement with respect
to Issuing Lender.

9.02    Delegation of Duties.  Administrative Agent may execute any of its duties under this Agreement or any other Loan Document by or through agents, employees or attorneys-in-fact and shall be entitled to advice of counsel concerning
all matters pertaining to such duties.  Administrative Agent shall not be responsible for the negligence or misconduct of any agent or attorney-in-fact that it selects with reasonable care.

9.03    Liability of Administrative Agent.  No Administrative Agent-Related Person shall (i) be liable for any action taken or omitted to be taken by any of them under or in connection with this Agreement or any other Loan Document or
the transactions contemplated hereby (except for its own gross negligence or willful misconduct), or (ii) be responsible in any manner to any Lender for any recital, statement, representation or warranty made by Borrower or any Subsidiary or Affiliate of Borrower, or
any officer thereof, contained in this Agreement or in any other Loan Document, or in any certificate, report, statement or other document referred to or provided for in, or received by Administrative Agent under or in connection with, this Agreement or any other
Loan Document, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document, or for any failure of Borrower or any other party to any Loan Document to perform its obligations hereunder or thereunder.  No
Administrative Agent-Related Person shall be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the
properties, books or records of Borrower or any of Borrower’s Subsidiaries or Affiliates.

9.04    Reliance by Administrative Agent.

(a)   Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, resolution, representation, notice, consent, certificate, affidavit, letter, telegram, facsimile, telex or telephone message, statement
or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel (including counsel to Borrower), independent accountants and other
experts selected by Administrative Agent. Administrative Agent shall be fully justified in failing or refusing to take any action under any other Loan Document unless it shall first receive such advice or concurrence of Requisite Lenders as it deems appropriate and,
if it so requests, it shall first be indemnified to its satisfaction by Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action.  Administrative Agent shall in all cases be fully
protected in acting, or in refraining from acting, under this Agreement or any other Loan Document in accordance with a request or consent of Requisite Lenders or all Lenders, if required hereunder, and such request and any action taken or failure to act pursuant
thereto shall be binding upon all of Lenders.  Where this Agreement expressly permits or prohibits an action

60

unless Requisite Lenders otherwise determine, and in all other instances, Administrative Agent may, but shall not be required to, initiate any solicitation for the consent or a vote of Lenders.

(b)   For purposes of determining compliance with the conditions specified in Section 4.01, each Lender that has executed this Agreement shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other
matter either sent by Administrative Agent to such Lender for consent, approval, acceptance or satisfaction, or required thereunder to be consented to or approved by or acceptable or satisfactory to such Lender.

(c)   Each Lender hereby authorizes Administrative Agent, upon payment of the amount certified by Borrower as the full and final payment of all principal, interest, fees and other charges outstanding under this Agreement, and following termination
of the Commitments, to execute with and in favor of Borrower a termination letter that, inter alia, terminates Borrower’s obligation to observe any or all of the covenants in Sections 3, 6 and 7 hereof.

9.05    Notice of Default.  Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, except with respect to defaults in the payment of principal, interest and fees
required to be paid to Administrative Agent for the account of Lenders, unless Administrative Agent shall have received written notice from a Lender or Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a
“notice of default”.  Administrative Agent will notify Lenders of its receipt of any such notice.  Administrative Agent shall take such action with respect to such Default or Event of Default as may be directed by Requisite Lenders in accordance
with Section 8; provided, however, that unless and until Administrative Agent has received any such direction, Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable or in the best interest of Lenders.

9.06    Credit Decision; Disclosure of Information by Administrative Agent.  Each Lender acknowledges that no Administrative Agent-Related Person has made any representation or warranty to it, and that no act by Administrative Agent
hereinafter taken, including any consent to and acceptance of any assignment or review of the affairs of Borrower and its Subsidiaries, shall be deemed to constitute any representation or warranty by any Administrative Agent-Related Person to any Lender as to any
matter, including whether Administrative Agent-Related Persons have disclosed material information in their possession.  Each Lender, including any Lender by assignment, represents to Administrative Agent that it has, independently and without reliance upon any
Administrative Agent-Related Person and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, prospects, operations, property, financial and other condition and creditworthiness of
Borrower and its Subsidiaries, and all applicable bank regulatory laws relating to the transactions contemplated hereby, and made its own decision to enter into this Agreement and to extend credit to Borrower hereunder.  Each Lender also represents that it will,
independently and without reliance upon any Administrative Agent-Related Person and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action
under this Agreement and the other Loan Documents, and to make such investigations as it deems necessary to inform itself as to the

61

business, prospects, operations, property, financial and other condition and creditworthiness of Borrower.  Except for notices, reports and other documents expressly required to be furnished to Lenders by Administrative Agent herein, Administrative Agent
shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of Borrower or any of its Subsidiaries which may come into
the possession of any Administrative Agent-Related Person.

9.07    Indemnification of Administrative Agent.  Whether or not the transactions contemplated hereby are consummated, Lenders shall indemnify upon demand each Administrative Agent-Related Person (to the extent not reimbursed by or on
behalf of Borrower and without limiting the obligation of Borrower to do so), ratably according to their Pro Rata Shares, and hold harmless each Administrative Agent-Related Person from and against any and all Indemnified Liabilities incurred by it; provided,
however, that no Lender shall be liable for the payment to any Administrative Agent-Related Person of any portion of such Indemnified Liabilities resulting from such Person’s gross negligence or willful misconduct; provided, however, that no action taken in
accordance with the directions of Requisite Lenders shall be deemed to constitute gross negligence or willful misconduct for purposes of this Section.  Without limitation of the foregoing, each Lender shall reimburse Administrative Agent upon demand for its
ratable share of any costs or out-of-pocket expenses (including Attorney Costs) incurred by Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any other Loan Document, or any document contemplated by or referred to herein, to the extent that Administrative Agent is not reimbursed for such expenses
by or on behalf of Borrower.  The undertaking in this Section shall survive the payment of all Obligations hereunder and the resignation or replacement of Administrative Agent.

9.08    Administrative Agent in Individual Capacity.  KeyBank and its Affiliates may make loans to, issue letters of credit for the account of, accept deposits from, acquire equity interests in and generally engage in any kind of
banking, trust, financial advisory, underwriting or other business with Borrower and its Subsidiaries and Affiliates as though KeyBank were not Administrative Agent or Issuing Lender hereunder and without notice to or consent of Lenders.  Lenders acknowledge
that, pursuant to such activities, KeyBank or its Affiliates may receive information regarding Borrower or its Affiliates (including information that may be subject to confidentiality obligations in favor of Borrower or such Affiliate) and acknowledge that
Administrative Agent shall be under no obligation to provide such information to them.  With respect to its Loans, KeyBank shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not
Administrative Agent or Issuing Lender.

9.09    Successor Administrative Agent.  Administrative Agent may, and at the request of Requisite Lenders shall, resign as Administrative Agent upon 30 days’ notice to Lenders.  If Administrative Agent resigns under this
Agreement, Requisite Lenders shall appoint from among Lenders a successor administrative agent for Lenders which successor administrative agent shall be approved by Borrower.  If no successor administrative agent is appointed prior to the effective date of the
resignation of Administrative Agent, Administrative Agent may appoint, after

62

consulting with Lenders and Borrower and upon approval of Borrower (other than at any time as there exists an Event of Default) which will not be unreasonably withheld, a successor administrative agent from among Lenders.  Upon the acceptance of its
appointment as successor administrative agent hereunder, such successor administrative agent shall succeed to all the rights, powers and duties of the retiring Administrative Agent and the term “Administrative Agent” shall mean such successor
administrative agent and the retiring Administrative Agent’s appointment, powers and duties as Administrative Agent shall be terminated.  After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of this
Section 9 and Sections 10.03 and 10.11 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement.  If no successor administrative agent has accepted appointment as Administrative Agent
(whether due to absence of Borrower approval or otherwise) by the date which is 30 days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective and
Lenders shall perform all of the duties of Administrative Agent hereunder until such time, if any, as Requisite Lenders appoint a successor agent as provided for above.  Notwithstanding the foregoing, however, KeyBank may not be removed as Administrative Agent
at the request of Requisite Lenders unless KeyBank shall also simultaneously be replaced as “Issuing Lender” hereunder pursuant to documentation in form and substance reasonably satisfactory to KeyBank.

9.10    Syndication Agent; Documentation Agent.  None of Lenders (or Affiliates of Lenders) identified on the facing page or signature pages of this Agreement as a “Syndication Agent” or “Documentation Agent”
shall have any right, power, obligation, liability, responsibility or duty under this Agreement in such capacity.  Without limiting the foregoing, none of Lenders (or Affiliates of Lenders) so identified shall have or be deemed to have any fiduciary relationship
with any Lender.  Each Lender acknowledges that it has not relied, and will not rely, on any of Lenders (or Affiliates of Lenders) so identified in deciding to enter into this Agreement or in taking or not taking action hereunder.

SECTION 10

MISCELLANEOUS

10.01    Amendments; Consents.  No amendment, modification, supplement, extension, termination or waiver of any provision of this Agreement or any other Loan Document, no approval or consent thereunder, no consent to any departure by
Borrower therefrom and no release of collateral in which Lenders have a security interest shall be effective unless in writing signed by Requisite Lenders and acknowledged by Administrative Agent, and each such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given.  Except as otherwise expressly provided herein, without the approval in writing of Administrative Agent and all Lenders, no amendment, modification, supplement, termination, waiver or consent may be
effective:

(a)   To reduce the amount of principal, principal prepayments or the rate of interest payable on, any Loan, or the amount of any fee or other amount payable to any Lender under the Loan Documents (unless such modification is consented to by each
Lender entitled to receive such fee ) or to waive an Event of Default consisting of the failure of Borrower to pay when due principal, interest or any commitment fee;

63

(b)   To postpone any date fixed for any payment of principal of, prepayment of principal of, or any installment of interest on, any Loan or any installment of any commitment fee, to extend the term of, or increase the amount of, any Lender’s
Commitment (it being understood that a waiver of an Event of Default shall not constitute an extension or increase in the Commitment of any Lender) or modify the Pro Rata Share of any Lender;

(c)   To release collateral in which Lenders have a security interest to secure the performance of Borrower's obligations under the Loan Documents constituting more than 20% of the value of Borrower's consolidated assets;

(d)   To amend the definition of “Requisite Lenders” or the provisions of Section 4, Section 9, this Section 10.01 or Section 10.06;

(e)   To amend Section 7.12(f); or

(f)   To amend any provision of this Agreement that expressly requires the consent or approval of all Lenders; provided, however, that (i) no amendment, waiver or consent shall, unless in writing and signed by Issuing Lender in addition to Requisite
Lenders or all Lenders, as the case may be, affect the rights or duties of Issuing Lender, (ii) no amendment, waiver or consent shall, unless in writing and signed by Administrative Agent in addition to Requisite Lenders or all Lenders, as the case may be, affect the
rights or duties of Administrative Agent, and (iii) the fee letters may be amended, or rights or privileges thereunder waived, in a writing executed by the parties thereto.  Any amendment, modification, supplement, termination, waiver or consent pursuant to this
Section shall apply equally to, and shall be binding upon, all Lenders and Administrative Agent.

10.02    Transmission and Effectiveness of Communications and Signatures.

(a)   Modes of Delivery.  Except as otherwise provided in any Loan Document, notices, requests, demands, directions, agreements and documents delivered in connection with the Loan Documents (collectively, “communications”)

provided, however, that communications delivered to Administrative Agent pursuant to Section 2 must be in writing and shall not be effective until actually received by Administrative Agent.

(b)   Reliance by Administrative Agent and Lenders.  Administrative Agent and Lenders shall be entitled to rely and act on any communications purportedly given by or on

64

behalf of Borrower even if (i) such communications (A) were not made in a manner specified herein, (B) were incomplete or (C) were not preceded or followed by any other notice specified herein, or (ii) the terms thereof, as understood by the recipient, varied from
any subsequent related communications provided for herein.  Borrower shall indemnify Administrative Agent and Lenders from any loss, cost, expense or liability as a result of relying on any communications permitted herein.

(c)   Effectiveness of Facsimile Documents and Signatures.  Documents and agreements delivered from time to time in connection with the Loan Documents may be transmitted and/or signed by facsimile.  The effectiveness of any such
documents and signatures shall, subject to applicable Law, have the same force and effect as hardcopies with manual signatures and shall be binding on all Borrower Parties and Administrative Agent and Lenders.  Administrative Agent may also request that any such
documents and signature be confirmed by a manually-signed hardcopy thereof; provided, however, that the failure to request or deliver any such manually-signed hardcopy shall not affect the effectiveness of any facsimile documents or signatures.

10.03    Attorney Costs, Expenses and Taxes.  Borrower agrees (a) to pay or reimburse Administrative Agent for all reasonable costs and expenses incurred in connection with the development, preparation, negotiation and execution
of the Loan Documents, and the development, preparation, negotiation and execution of any amendment, waiver, consent, supplement or modification to, any Loan Documents, and any other documents prepared in connection herewith or therewith, and the consummation and
administration of the transactions contemplated hereby and thereby, including all reasonable Attorney Costs, and (b) to pay or reimburse Administrative Agent and each Lender for all costs and expenses incurred in connection with any refinancing, restructuring,
reorganization (including a bankruptcy reorganization), collection and enforcement or attempted enforcement, or preservation of any rights under any Loan Documents, and any other documents prepared in connection herewith or therewith, or in connection with any
refinancing, or restructuring of any such documents in the nature of a “workout” or of any insolvency or bankruptcy proceeding, including Attorney Costs.  The foregoing costs and expenses shall include all reasonable search, filing, recording, title
insurance and appraisal charges and fees and taxes related thereto, and other out-of-pocket expenses incurred by Administrative Agent and the cost of independent public accountants and other outside experts retained by Administrative Agent or any Lender.  Such
costs and expenses shall also include administrative costs of Administrative Agent reasonably attributable to the administration of the Loan Documents.  Any amount payable by Borrower under this Section shall bear interest from the second Business Day following
the date of demand for payment at the Default Rate, unless waived by Administrative Agent.  The agreements in this Section shall survive repayment of all Obligations.

10.04    Binding Effect; Assignment.

(a)   This Agreement and the other Loan Documents to which Borrower is a party will be binding upon and inure to the benefit of Borrower, Administrative Agent, Lenders and their respective successors and assigns, except that, Borrower may not assign
its rights hereunder or thereunder or any interest herein or therein without the prior written consent of all Lenders and any such attempted assignment shall be void.  Any Lender may at any time pledge its Note or

65

any other instrument evidencing its rights as a Lender under this Agreement to a Federal Reserve Bank, but no such pledge shall release such Lender from its obligations hereunder or grant to such Federal Reserve Bank the rights of a Lender hereunder absent
foreclosure of such pledge.

(b)   From time to time following the Closing Date, each Lender may assign to one or more Eligible Assignees all or any portion of its Commitment and/or Extensions of Credit; provided that (i) such assignment, if not to a Lender or an Affiliate of
the assigning Lender, shall be consented to by Borrower at all times other than during the existence of a Default or Event of Default and by Administrative Agent and Issuing Lender (which approval of Borrower shall not be unreasonably withheld), (ii) a copy of a duly
signed and completed Assignment and Acceptance shall be delivered to Administrative Agent, (iii) except in the case of an assignment (A) to an Affiliate of the assigning Lender or to another Lender or (B) of the entire remaining Commitment of the assigning Lender,
the portion of the Commitment assigned shall not be less than the Minimum Amount therefor, and (iv) the effective date of any such assignment shall be as specified in the Assignment and Acceptance, but not earlier than the date which is five Business Days after the
date Administrative Agent has received the Assignment and Acceptance.  Upon any required consent by Administrative Agent, Issuing Lender and Borrower to such assignment and payment of the requisite fee described below, the assignee named therein shall be a
Lender for all purposes of this Agreement, with the Pro Rata Share therein set forth and, to the extent of such Pro Rata Share, the assigning Lender shall be released from its further obligations under this Agreement.  Borrower agrees that it shall execute and
deliver upon request (against delivery by the assigning Lender to Borrower of any Note) to such assignee Lender, one or more Notes evidencing such assignee Lender’s Loans, and to the assigning Lender if requested, one or more Notes evidencing Loans under any
Commitment retained by the assigning Lender.  Administrative Agent’s consent to any assignment shall not be deemed to constitute any representation or warranty by any Administrative Agent-Related Person as to any matter.  For purposes hereof, each
mutual fund that is an Affiliate of a Lender shall be deemed to be a single Eligible Assignee, whether or not such fund is managed by the same fund manager as other mutual funds that are Affiliates of the same Lender.

(c)   After receipt of a completed Assignment and Acceptance, and receipt of an assignment fee of $3,500 from such Eligible Assignee (including in the case of assignments to Affiliates of assigning Lenders), Administrative Agent shall, promptly
following the effective date thereof, provide to Borrower and Lenders a revised Schedule 10.02 giving effect thereto.

(d)   Each Lender may from time to time, without the consent of any other Person, grant participations to one or more other Person (including another Lender) of all or any portion of its Pro Rata Share of its Commitment or Extensions of Credit;
provided, however, 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, (iii) the participating banks or other
financial institutions shall not be a Lender hereunder for any purpose except, if the participation agreement so provides, for the purposes of Section 3 (but only to the extent that the cost of such benefits to Borrower does not exceed the cost which Borrower would
have incurred in respect of such Lender absent the participation) and subject to Sections 10.05 and 10.06, (iv) Borrower, Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s
rights and obligations under this Agreement, (v) the participation agreement shall not restrict an increase in the

66

combined Commitments or in granting Lender’s Pro Rata Share, so long as the amount of the participation interest is not affected thereby, and (vi) the consent of the holder of such participation interest shall not be required for amendments or waivers of
provisions of the Loan Documents; provided, however, that the assigning Lender may, in any agreement with a participant, give such participant the right to consent to any matter which (A) extends the Maturity Date as to such participant or any other date upon which
any payment of money is due to such participant, (B) reduces the rate of interest owing to such participant, any fee or any other monetary amount owing to such participant, or (C) reduces the amount of any installment of principal owing to such participant.  Any
Lender that sells a participation to any Person that is a “foreign corporation, partnership or trust” within the meaning of the Code shall include in its participation agreement with such Person a covenant by such Person that such Person will comply with
the provisions of Section 10.21 as if such Person were a Lender and provide that Administrative Agent and Borrower shall be third party beneficiaries of such covenant.

10.05    Set-off.  In addition to any rights and remedies of Administrative Agent and Lenders or any assignee or participant of any Lender or any Affiliate thereof (each, a “Proceeding Party”) provided by law, upon the
occurrence and during the continuance of any Event of Default, each Proceeding Party is authorized at any time and from time to time, without prior notice to Borrower, any such notice being waived by Borrower to the fullest extent permitted by law, to proceed
directly, by right of set-off, banker’s lien, or otherwise, against any assets of Borrower Parties which may be in the hands of such Proceeding Party (including all general or special, time or demand, provisional or other deposits and other indebtedness owing
by such Proceeding Party to or for the credit or the account of Borrower) and apply such assets against the Obligations, irrespective of whether such Proceeding Party shall have made any demand therefor and although such Obligations may be unmatured.  Each
Lender agrees promptly to notify Borrower and Administrative Agent after any such set-off and application made by such Lender; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application.

10.06    Sharing of Payments.  Each Lender severally agrees that if it, through the exercise of any right of setoff, banker’s lien or counterclaim against Borrower or otherwise, receives payment on account of the Outstanding
Obligations held by it that is ratably more than any other Lender receives in payment on account of the Outstanding Obligations held by such other Lender, then, subject to applicable Laws:  (a) the Lender exercising the right of setoff, banker’s lien or
counterclaim or otherwise receiving such payment shall purchase, and shall be deemed to have simultaneously purchased, from the other Lender a participation in the Outstanding Obligations held by the other Lender and shall pay to the other Lender a purchase price in
an amount so that the share of the Outstanding Obligations held by each Lender after the exercise of the right of setoff, banker’s lien or counterclaim or receipt of payment shall be in the same proportion that existed prior to the exercise of the right of
setoff, banker’s lien or counterclaim or receipt of payment; and (b) such other adjustments and purchases of participations shall be made from time to time as shall be equitable to ensure that all Lenders share any payment obtained in respect of the Outstanding
Obligations ratably in accordance with each Lender’s share of the Outstanding Obligations immediately prior to, and without taking into account, the payment; provided that, if all or any portion of a disproportionate payment obtained as a result of the exercise
of the right of setoff, banker’s lien, counterclaim or otherwise is thereafter recovered from the purchasing Lender by Borrower or any Person claiming through or

67

succeeding to the rights of Borrower, the purchase of a participation shall be rescinded and the purchase price thereof shall be restored to the extent of the recovery, but without interest.  Each Lender that purchases a participation in the Outstanding
Obligations pursuant to this Section shall from and after the purchase have the right to give all notices, requests, demands, directions and other communications under this Agreement with respect to the portion of the Outstanding Obligations purchased to the same
extent as though the purchasing Lender were the original owner of the Outstanding Obligations purchased.  Borrower expressly consents to the foregoing arrangements and agrees that any Lender holding a participation in an Obligation so purchased may exercise any
and all rights of setoff, banker’s lien or counterclaim with respect to the participation as fully as if Lender were the original owner of the Obligation purchased.

10.07    No Setoff.  As to any and all funds, securities or other assets of Borrower which are now or hereafter held by Administrative Agent or any Lender as collateral pursuant to this Agreement or any other Loan Document for any
of the obligations thereunder (including, without limitation, all amounts in the Supplemental Borrowing Account and any other deposit account, securities account or other similar account) (collectively the "Collateral Assets"), Administrative Agent and the Lenders
agree that they shall not exercise any right of setoff or recoupment against nor shall they assert any security interest in the Collateral Assets in connection with any other obligation owed to Administrative Agent or any Lender which is unrelated to this Agreement
or the Loan Documents, except for:  (i) recovery for any items deposited with Administrative Agent or any Lender and returned unpaid or as to which claims have been asserted as to breach of transfer or presentment warranties, (ii) overdrafts on any account which
generated the funds which constitute part of the Collateral Assets, (iii) automated clearing house entries, and (iv) Administrative Agent or any Lender's usual and customary fees for services rendered in connection with the assets or bank accounts which constitute
the Collateral Assets.

10.08    No Waiver; Cumulative Remedies.

(a)   No failure by any Lender or Administrative Agent to exercise, and no delay by any Lender or Administrative Agent in exercising, any right, remedy, power or privilege hereunder, shall operate as a waiver thereof; nor shall any single or partial
exercise of any right, remedy, power or privilege under any Loan Document preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.  Without limiting the generality of the foregoing, the terms and conditions
of Section 4 may be waived in whole or in part, with or without terms or conditions, in respect of any Extension of Credit without prejudicing Administrative Agent’s or Lenders’ rights to assert them in whole or in part in respect of any other Extension
of Credit.

(b)   The rights, remedies, powers and privileges herein or therein provided are cumulative and not exclusive of any rights, remedies, powers and privileges provided by Law. Any decision by Administrative Agent or any Lender not to require payment
of any interest (including Default Interest), fee, cost or other amount payable under any Loan Document or to calculate any amount payable by a particular method on any occasion shall in no way limit or be deemed a waiver of Administrative Agent’s or such
Lender’s right to require full payment thereof, or to calculate an amount payable by another method that is not inconsistent with this Agreement, on any other or subsequent occasion.

68

(c)   The terms and conditions of Section 9 are for the sole benefit of Administrative Agent and Lenders.

10.09    Usury.  Notwithstanding anything to the contrary contained in any Loan Document, the interest and fees paid or agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by
applicable Law (the “Maximum Rate”).  If Administrative Agent or any Lender shall receive interest or a fee in an amount that exceeds the Maximum Rate, the excessive interest or fee shall be applied to the principal of the Outstanding
Obligations or, if it exceeds the unpaid principal, refunded to Borrower.  In determining whether the interest or a fee contracted for, charged, or received by Administrative Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by
applicable Law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total
amount of interest throughout the contemplated term of the Obligations.

10.10    Counterparts.  This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

10.11    Integration.  This Agreement, together with the other Loan Documents and any letter agreements referred to herein, comprises the complete and integrated agreement of the parties on the subject matter hereof and supersedes all
prior agreements, written or oral, on the subject matter hereof.  In the event of any conflict between the provisions of this Agreement and those of any other Loan Document, the provisions of this Agreement shall control and govern; provided that the inclusion
of supplemental rights or remedies in favor of Administrative Agent or Lenders in any other Loan Document shall not be deemed a conflict with this Agreement.  Each Loan Document was drafted with the joint participation of the respective parties thereto and shall
be construed neither against nor in favor of any party, but rather in accordance with the fair meaning thereof.

10.12    Nature of Lenders’ Obligations.  Nothing contained in this Agreement or any other Loan Document and no action taken by Administrative Agent or Lenders or any of them pursuant hereto or thereto may, or may be deemed to,
make Lenders a partnership, an association, a joint venture or other entity, either among themselves or with Borrower or any Affiliate of Borrower.  Each Lender’s obligation to make any Extension of Credit pursuant hereto is several and not joint or joint
and several, and in the case of the initial Extension of Credit only is conditioned upon the performance by all other Lenders of their obligations to make the initial Extension of Credit.  A default by any Lender will not increase the Pro Rata Share attributable
to any other Lender.

10.13    Survival of Representations and Warranties.  All representations and warranties made hereunder and in any Loan Document, certificate or statement delivered pursuant hereto or thereto or in connection herewith or therewith shall
survive the execution and delivery thereof but shall terminate the later of (a) when the Commitments are terminated and (b) when no Obligations remain outstanding under any Loan Document.  Such representations and warranties have been or will be relied upon by
Administrative Agent and each Lender,

69

notwithstanding any investigation made by Administrative Agent or any Lender or on their behalf.

10.14    Indemnity by Borrower.  Borrower agrees to indemnify, defend, save and hold harmless each Administrative Agent-Related Person and each Lender and their respective Affiliates, directors, officers, agents, attorneys and employees
(collectively, the “Indemnitees”) from and against:  (a) any and all claims, demands, actions or causes of action that are asserted against any Indemnitee by any Person (other than Administrative Agent or any Lender) relating directly or indirectly
to a claim, demand, action or cause of action that such Person asserts or may assert against Borrower, any of its Affiliates or any its officers or directors; (b) any and all claims, demands, actions or causes of action arising out of or relating to, the Loan
Documents, any predecessor loan documents, the Commitments, the use or contemplated use of the proceeds of any Loan, the Colorado Springs Real Property Security, property that is the subject of any Material Lease or any other collateral given to secure the
obligations of Borrower under this Agreement, or the relationship of Borrower, Administrative Agent and Lenders under this Agreement; (c) any administrative or investigative proceeding by any Governmental Authority arising out of or related to a claim, demand, action
or cause of action described in subsection (a) or (b) above; and (d) all liabilities, claims, actions, loss, damages, including, without limitation, foreseeable and unforeseeable consequential damages, costs and expenses (including sums paid in settlement of claims
and all consultant, expert and legal fees and expenses of Indemnitees' counsel) directly or indirectly arising out of or resulting from any Hazardous Substance being present at any time in or around any part of the Colorado Real Property Security, or in the soil,
groundwater or soil vapor on or under the Colorado Real Property Security, including those incurred in connection with any investigation of site conditions or any clean-up, remedial, removal or restoration work, or any resulting damages or injuries to the person or
property of any third parties or to any natural resources; (e) any and all liabilities, losses, costs or expenses (including Attorney Costs) that any Indemnitee suffers or incurs as a result of the assertion of any foregoing claim, demand, action, cause of action or
proceeding, or as a result of the preparation of any defense in connection with any foregoing claim, demand, action, cause of action or proceeding, in all cases, whether or not an Indemnitee is a party to such claim, demand, action, cause of action or proceeding,
including those liabilities caused by an Indemnitee’s own negligence (all the foregoing, collectively, the “Indemnified Liabilities”); provided that no Indemnitee shall be entitled to indemnification for any loss caused by its own gross negligence
or willful misconduct or for any loss asserted against it by another Indemnitee.

10.15    Nonliability of Lenders.

Borrower acknowledges and agrees that:

(a)   Any inspections of any property of Borrower made by or through Administrative Agent or Lenders are for purposes of administration of the Loan Documents only, and Borrower is not entitled to rely upon the same (whether or not such inspections
are at the expense of Borrower);

(b)   By accepting or approving anything required to be observed, performed, fulfilled or given to Administrative Agent or Lenders pursuant to the Loan Documents, neither Administrative Agent nor Lenders shall be deemed to have warranted or
represented the

70

sufficiency, legality, effectiveness or legal effect of the same, or of any term, provision or condition thereof, and such acceptance or approval thereof shall not constitute a warranty or representation to anyone with respect thereto by Administrative Agent or
Lenders;

(c)   The relationship between Borrower and Administrative Agent and Lenders is, and shall at all times remain, solely that of borrower and lenders; neither Administrative Agent nor any Lender shall under any circumstance be deemed to be in a
relationship of confidence or trust or a fiduciary relationship with Borrower or its Affiliates, or to owe any fiduciary duty to Borrower or its Affiliates; neither Administrative Agent nor any Lender undertakes or assumes any responsibility or duty to Borrower or
its Affiliates to select, review, inspect, supervise, pass judgment upon or inform Borrower or its Affiliates of any matter in connection with their property or the operations of Borrower or its Affiliates; Borrower and its Affiliates shall rely entirely upon their
own judgment with respect to such matters; and any review, inspection, supervision, exercise of judgment or supply of information undertaken or assumed by Administrative Agent or any Lender in connection with such matters is solely for the protection of
Administrative Agent and Lenders and neither Borrower nor any other Person is entitled to rely thereon; and

(d)   Neither Administrative Agent nor any Lender shall be responsible or liable to any Person for any loss, damage, liability or claim of any kind relating to injury or death to Persons or damage to property caused by the actions, inaction or
negligence of Borrower and/or its Affiliates and Borrower hereby indemnifies and holds Administrative Agent and Lenders harmless from any such loss, damage, liability or claim.

10.16    No Third Parties Benefited.  This Agreement is made for the purpose of defining and setting forth certain obligations, rights and duties of Borrower, Administrative Agent and Lenders in connection with the Extensions of Credit,
and is made for the sole benefit of Borrower, Administrative Agent and Lenders, and Administrative Agent’s and Lenders’ successors and assigns.  Except as provided in Sections 10.04 and 10.13, no other Person shall have any rights of any nature
hereunder or by reason hereof.

10.17    Severability.  Any provision of the Loan Documents that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating
the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

10.18    Confidentiality.  Administrative Agent and each Lender shall use any confidential non-public information concerning Borrower and its Subsidiaries that is furnished to Administrative Agent or such Lender by or on behalf of
Borrower and its Subsidiaries in connection with the Loan Documents (collectively, “Confidential Information”) solely for the purpose of evaluating and providing products and services to them and administering and enforcing the Loan Documents, and
it will hold the Confidential Information in confidence.  Notwithstanding the foregoing, Administrative Agent and each Lender may disclose Confidential Information (a) to their Affiliates or any of their or their Affiliates’ directors, officers, employees,
advisors, or representatives (collectively, the “Representatives”) whom it determines need to know such information for the purposes set forth in this Section; (b) to any

71

bank or financial institution or other entity to which such Lender has assigned or desires to assign an interest or participation in the Loan Documents or the Obligations, provided that any such foregoing recipient of such Confidential Information agrees to keep
such Confidential Information confidential as specified herein; (c) to any governmental agency or regulatory body having or claiming to have authority to regulate or oversee any aspect of Administrative Agent’s or such Lender’s business or that of its
Representatives in connection with the exercise of such authority or claimed authority; (d) to the extent necessary or appropriate to effect or preserve Administrative Agent’s or such Lender’s or any of their Affiliates’ security (if any) for any
Obligation or to enforce any right or remedy or in connection with any claims asserted by or against Administrative Agent or such Lender or any of their Representatives; and (e) pursuant to any subpoena or any similar legal process.  For purposes hereof, the
term “Confidential Information” shall not include information that (x) is in Administrative Agent’s or a Lender’s possession prior to its being provided by or on behalf of the Borrower Parties, provided that such information is not known by
Administrative Agent or such Lender to be subject to another confidentiality agreement with, or other legal or contractual obligation of confidentiality to, Borrower, (y) is or becomes publicly available (other than through a breach hereof by Administrative Agent or
such Lender), or (z) becomes available to Administrative Agent or such Lender on a nonconfidential basis, provided that the source of such information was not known by Administrative Agent or such Lender to be bound by a confidentiality agreement or other legal or
contractual obligation of confidentiality with respect to such information.

10.19    Further Assurances.  Borrower and its Subsidiaries shall, at their expense and without expense to Lenders or Administrative Agent, do, execute and deliver such further acts and documents as any Lender or Administrative Agent
from time to time reasonably requires for the assuring and confirming unto Lenders or Administrative Agent of the rights hereby created or intended now or hereafter so to be, or for carrying out the intention or facilitating the performance of the terms of any Loan
Document.

10.20    Headings.  Section headings in this Agreement and the other Loan Documents are included for convenience of reference only and are not part of this Agreement or the other Loan Documents for any other purpose.

10.21    Time of the Essence.  Time is of the essence of the Loan Documents.

10.22    Foreign Lenders.  Each Lender that is a “foreign corporation, partnership or trust” within the meaning of the Code (a "Foreign Lender") shall deliver to Administrative Agent, prior to receipt of any payment
subject to withholding under the Code (or after accepting an assignment of an interest herein), two duly signed completed copies of either Form W-8BEN or any successor thereto (relating to such Person and entitling it to a complete exemption from withholding on all
payments to be made to such Person by Borrower pursuant to this Agreement) or Form W-8ECI or any successor thereto (relating to all payments to be made to such Person by Borrower pursuant to this Agreement) of the United States Internal Revenue Service or such other
evidence satisfactory to Borrower and Administrative Agent that no withholding under the federal income tax laws is required with respect to such Person.  Thereafter and from time to time, each such Person shall (a) promptly submit to Administrative Agent such
additional duly completed and signed copies of one of such forms (or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities) as may then be available under

72

then current United States laws and regulations to avoid, or such evidence as is satisfactory to Borrower and Administrative Agent of any available exemption from, United States withholding taxes in respect of all payments to be made to such Person by Borrower
pursuant to this Agreement, and (b) take such steps as shall not be materially disadvantageous to it, in the reasonable judgment of such Lender, and as may be reasonably necessary (including the re-designation of its Lending Office) to avoid any requirement of
applicable Laws that Borrower make any deduction or withholding for taxes from amounts payable to such Person.  If such Persons fails to deliver the above forms or other documentation, then Administrative Agent may withhold from any interest payment to such
Person an amount equivalent to the applicable withholding tax imposed by Sections 1441 and 1442 of the Code, without reduction.  If any Governmental Authority asserts that Administrative Agent did not properly withhold any tax or other amount from payments made
in respect of such Person, such Person shall indemnify Administrative Agent therefor, including all penalties and interest and costs and expenses (including Attorney Costs) of Administrative Agent.  The obligation of Lenders under this Section shall survive the
payment of all Obligations and the resignation or replacement of Administrative Agent.

10.23    Removal and Replacement of Lenders.

(a)   Under any circumstances set forth in this Agreement providing that Borrower shall have the right to remove and replace a Lender as a party to this Agreement, Borrower may, upon notice to such Lender and Administrative Agent, remove such Lender
by (i) non ratably terminating such Lender’s Commitment, and (ii) if being replaced, causing such Lender to assign its Commitment to one or more other Lenders or Eligible Assignees acceptable to Borrower, Administrative Agent and Issuing Lender; provided,
however, that during the existence of any Event of Default, Borrower may not remove or replace a Lender pursuant to this Section 10.22.  Any removed or replaced Lender shall be entitled to (x) payment in full of all principal, interest, fees and other amounts
owing to such Lender or such Lender’s affiliated Indemnitees under any Loan Document through the date of termination or assignment (including any amounts payable pursuant to Section 3.05), (y) appropriate assurances and indemnities (which may include letters of
credit) as such Lender may reasonably require with respect to its participation interest in any Letters of Credit and (z) a release of such Lender from its obligations under the Loan Documents.  Any Lender being replaced shall execute and deliver an Assignment
and Acceptance covering such Lender’s Commitment, and shall otherwise comply with Section 10.04.  Administrative Agent shall distribute an amended Schedule 2.01, which shall thereafter be incorporated into this Agreement, to reflect adjustments to Lenders
and their Commitments.

(b)   In order to make all Lender’s interests in any outstanding Extensions of Credit ratable in accordance with any revised Pro Rata Shares after giving effect to the removal or replacement of a Lender, Borrower shall pay or prepay, if
necessary, on the effective date thereof, all outstanding Extensions of Credit of all Lenders, together with any amounts due under Section 3.05.  Borrower may then request Extensions of Credit from Lenders in accordance with their revised Pro Rata Shares.

73

10.24    Governing Law.

(a)   THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF CALIFORNIA APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE; PROVIDED THAT ADMINISTRATIVE AGENT AND EACH LENDER SHALL
RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

(b)   ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF CALIFORNIA OR OF THE UNITED STATES FOR THE CENTRAL DISTRICT OF SUCH STATE, AND BY EXECUTION AND DELIVERY OF
THIS AGREEMENT, BORROWER, ADMINISTRATIVE AGENT AND EACH LENDER CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF THOSE COURTS.  BORROWER, ADMINISTRATIVE AGENT AND EACH LENDER IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY
OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT OF ANY LOAN DOCUMENT OR OTHER DOCUMENT RELATED HERETO. 
BORROWER, ADMINISTRATIVE AGENT AND EACH LENDER WAIVES PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS PERMITTED BY THE LAW OF SUCH STATE.

10.25    Judicial Reference Waiver of Jury Trial.  In all the Loan Documents the sections regarding “Jury Trial Waiver” are hereby deleted in their entirety and all claims in connection with the Loan Documents shall be
determined by a consensual general judicial reference, pursuant to the provisions of California Code of Civil Procedure§§ 638 et seq., as such statutes may be amended or modified from time to time, and as more fully set forth in Exhibit E.

10.26    Entire Agreement.  This Agreement and the other Loan Documents represent the final agreement between the parties and may not be contradicted by evidence of prior, contemporaneous, or subsequent oral agreements of the
parties.  There are no unwritten oral agreements between the parties.

CORPORATION, an Ohio corporation, as Lessor (together with its permitted successors and assigns, the "Lessor"); COMERICA BANK and KEYBANK NATIONAL ASSOCIATION, as Participants and SELCO SERVICE CORPORATION, in its capacity as a Participant
(together with their permitted successors and assigns, each a "Participant" and collectively the "Participants"); and KEYBANK NATIONAL ASSOCIATION (in such capacity, together with its successors in such capacity, the "Agent") for the Participants.

RECITALS

A.  Lessee, Lessor, Agent and Participants are parties to a Participation Agreement dated as of December 17, 2002, as amended by that certain First Amendment to Participation Agreement dated as of January 31, 2003, that certain Second Amendment to
Participation Agreement dated as of July 21, 2003, that certain Third Amendment to Participation Agreement dated as of March 30, 2004, and that certain Fourth Amendment to Participation Agreement dated as of January 5, 2005 and that certain Fifth Amendment to
Participation Agreement dated May 26, 2005 (collectively, the "Participation Agreement")..

B.  Lessee has requested that the Lessor, Agent and Participants amend the Participation Agreement and certain other of the Operative Documents, and Lessor, Agent and Participants have agreed, subject to satisfaction of the conditions set forth herein, to
modify certain terms and covenants of Lessee under the Operative Documents.

C.  Each capitalized term used but not otherwise defined herein shall have the meaning ascribed thereto in Appendix 1 to the Participation Agreement.

NOW, THEREFORE, the parties hereto agree as follows:

ARTICLE 1

AMENDMENTS TO PARTICIPATION AGREEMENT

This Amendment shall be deemed to be an amendment to the Participation Agreement and shall not be construed in any way as a replacement or substitution therefor.  All of the terms and conditions of, and terms defined in, this Amendment are hereby incorporated
by reference into the Participation Agreement as if such terms and provisions were set forth in full therein.

1.1  Section 10.1(a) of the Participation Agreement is amended to include a new subsection (iv) as follows:

“(iv)  such other financial reports as Agent may reasonably request from Lessee,

1

including without limitation, an annual budget fro the Lessee’s next fiscal year to be delivered within 30 days after the end of each fiscal year of Lessee.

1.2  Section 10.2(a)(iv) of the Participation Agreement is amended and restated in its entirety as follows:

"(iv)    Indebtedness of Lessee under the New Convertible Subordinated Notes;"

1.3  Section 10.2(a)(x) of the Participation Agreement is amended and restated in its entirety as follows:

"(x)      Subordinated Indebtedness of Lessee to any Person, provided that (A) such Indebtedness contains subordination provisions no less favorable to Agent and the Participants than those set forth in Exhibit O or as
otherwise approved by the Required Participants and (B) the aggregate principal amount of all Subordinated Debt of Lessee outstanding (including the New Convertible Subordinated Notes) does not exceed $350,000,000 at any time, and"

1.4  Section 10.2(e) (v) of the Participation Agreement is amended and restated in its entirety as follows:

“(v)  Investments in the nature of Permitted Acquisitions;”

1.5  Section 10.2(j) of the Participation Agreement is amended and restated in its entirety as follows:

(j)        Certain Indebtedness Payments, Etc.  Neither Lessee nor any of its Subsidiaries shall pay, prepay, redeem, purchase, defease or otherwise satisfy in any manner prior to the scheduled payment thereof any
Subordinated Debt except as otherwise permitted under this Section 10.2(j); amend, modify or otherwise change the terms of any document, instrument or agreement evidencing Subordinated Debt such that such amendment, modification or change would (i) cause the
outstanding aggregate principal amount of all such Subordinated Debt so amended, modified or changed to be increased as a consequence of such amendment, modification or change, (ii) cause the subordination provisions applicable to such Subordinated Debt to be less
favorable to Agent and the Participants than those set forth on Exhibit O, (iii) increase the interest rate applicable thereto, or (iv) accelerate the scheduled payment thereof.  Lessee shall not cause or permit any of its obligations, except the
obligations constituting Senior Indebtedness to constitute "Designated Senior Indebtedness" under the Indenture governing the New Convertible Subordinated Debentures (it being understood that the obligations of Lessee under the Operative Documents shall at all times
constitute "Designated Senior Indebtedness" under both such indentures).  Notwithstanding the foregoing, Lessee at any time:

(1) conduct an exchange offer (whether public, private or on a 3(a)(9) basis) of all or part of the Lessee’s New Convertible Subordinated Notes for one

2

or more of the following:  (a) new securities ("New Securities") that are subordinated in right of payment to the obligations of Lessee under the Operative Documents at least to the same extent as the existing New Convertible Subordinated Notes; provided that
(w) the aggregate annual interest obligation of Lessee under the New Securities shall be equal to or less than the aggregate annual interest obligation under the existing New Convertible Subordinated Notes, (x) the maturity date of the New Securities shall not be
earlier than the maturity date of the existing New Convertible Subordinated Notes, as applicable, (y) the total principal amount of the obligations represented by Lessee's Subordinated Debt shall not be increased by means of any exchange of the New Securities for all
or part of the New Convertible Subordinated Notes, and (z) the New Securities shall not permit any amortization of the principal amount of the obligations represented thereby prior to the maturity of the existing New Convertible Subordinated Notes; or

Notwithstanding any provision of this Section 10.2(j) to the contrary, Lessee may (A) convert, or honor a conversion request with respect to, any such Subordinated Debt into Equity Securities of Lessee in accordance with the terms thereof; (B) pay cash to holders
of such Subordinated Debt in connection with such a conversion but solely to the extent representing the value of any fractional shares; (C) make payments of interest on such Subordinated Debt not in violation of the Subordination provisions of such Subordinated
Debt; (D) pay the redemption premium, if any, owing in connection with any redemption of all or part of the Convertible Subordinated Debentures; (E) pay additional interest in an amount not to exceed 50 basis points per annum of the aggregate principal amount of the
New Convertible Subordinated Notes to the extent due under the provisions of the New Convertible Subordinated Notes due to Lessee's failure to register such notes or shares of common stock into which the notes are convertible within the period or to keep such notes
or shares registered for or during the periods specified in the indenture for the New Convertible Subordinated Notes or the Registration Rights Agreement; and (F) make other payments, repayments, redemptions, purchases, defeasance or other satisfaction of
Subordinated Debt not to exceed $5,000,000 in the aggregate.

3

1.9  Maximum Senior Indebtedness.  Section 10.2(k)(v) of the Participation Agreement is amended and restated in its entirety as follows:

(v)       Maximum Senior Indebtedness.  Permit Senior Indebtedness of Lessee and its Subsidiaries on a consolidated basis to exceed at any time outstanding $145,000,000.

1.10  Minimum Unrestricted Cash.  Section 10.2(k)(vii) of the Participation Agreement is amended and restated in its entirety as follows:

(vii)     Minimum Unrestricted Cash.  Permit Lessee’s Consolidated Cash Balance (as defined in Section 10.1(b)(ii)) at any time to fall below $50,000,000.  Lessee shall maintain the Consolidated Cash Balance of at least
$50,000,000 deposited in domestic accounts subject to the Deposit Account Control Agreements and Securities Account Control Agreements.  The covenant that Lessee shall not permit its overall Consolidated Cash Balance to fall below $50,000,000 shall apply at all
times and shall be tested monthly in accordance with such reports.

1.11  Section 15.14 of the Participation Agreement is deleted in its entirety and replaced with the following:

amended or modified from time to time, and as more fully set forth in Schedule 5, attached hereto and made a part hereof, which will be new Exhibit P to the Participation Agreement.

1.12  Consolidated EBITDA.  The definition of “Consolidated EBITDA” set forth in Appendix 1 to the Participation Agreement shall be amended and restated in its entirety as follows:
