The Term Loan shall be made pro rata in accordance with each Lender’s Commitment Percentage. The request for the Term Loan made pursuant to §2.4 shall constitute a representation and warranty by the Borrower that the conditions set forth in §12 and §13 have been satisfied as of the Closing Date, provided that the making of such representation and warranty by the Borrower shall not limit the right of any Lender not to lend if such conditions have not been met. No portion of the Term Loan shall be required to be made by any Lender unless all of the conditions contained in §12 and §13 have been satisfied as of the Closing Date.

§2.2. The Term Notes. The Term Loan shall be evidenced by the Term Notes. A Term Note shall be payable to the order of each Lender in an aggregate principal amount equal to such Lender’s Commitment. The Borrower irrevocably authorizes each Lender to make or cause to be made, on the Closing Date and at the time of receipt of any payment of principal on such Lender’s Term Note, an appropriate notation on such Lender’s applicable Note Record reflecting the making of such Loan or (as the case may be) the receipt of such payment. The outstanding amount of the Loan set forth on such applicable Note Record shall be prima facie evidence of the principal amount of the Term Loan owing and unpaid to such Lender, but the failure to record, or any error in so recording, any such amount on such Note Record shall not limit or otherwise affect the rights and obligations of the Borrower hereunder or under any Term Note to make payments of principal of or interest on any Term Note when due.

§2.3. Interest on Term Loan; Fees.

(a) Each Base Rate Loan shall bear interest for the period commencing with the Drawdown Date thereof and ending on the last day of the Interest Period with respect thereto (unless earlier paid in accordance with §3.2) at a rate equal to the Base Rate.

(b) Each Libor Rate Loan shall bear interest for the period commencing with the Drawdown Date thereof and ending on the last day of the Interest Period with respect thereto (unless earlier paid in accordance with §3.2) at a rate equal to the Libor Rate determined for such Interest Period plus the Applicable Libor Margin.

(d) The Borrower unconditionally promises to pay interest on the Term Loan in arrears on each Interest Payment Date with respect thereto, and when the principal of such Term Loan is due (whether at maturity, by reason of acceleration or otherwise).

§2.4. Request for the Term Loan.

The following provisions shall apply to the request by the Borrower for the Term Loan:

(a) The Borrower shall submit a Completed Loan Request to the Agent, together with a duplicate copy of such Completed Loan Request for each Lender which is then a party to this Agreement at the time such loan request is made. The Completed Loan Request shall be irrevocable and binding on the Borrower and shall obligate the Borrower to accept the Term Loan requested from the Lenders on the Closing Date.

(b) The Completed Loan Request shall include a completed certificate in the form of Exhibit B hereto specifying: (1) the principal amount of the Term Loan requested, (2) the Interest Period applicable to the Term Loan, and (3) the Type of Loan being requested, and certifying that, both before and after giving effect to the making of the Term Loan, no Default or Event of Default exists or will exist under this Agreement or any other Loan Document.


	(i) a Completed Loan Request has been received by the Agent as provided in clause (a) above; and

	(ii) both before and after giving effect to the Term Loan to be made pursuant to the Completed Loan Request, all of the conditions contained in §12 and §13 shall have been satisfied as of the Closing Date.

(d) The Agent will promptly notify each Lender of the Completed Loan Request and will cause a copy thereof to be delivered to each Lender on the Closing Date.

§2.5. Conversion Options.

(a) The Borrower may elect from time to time to convert any portion of the outstanding Term Loan to a Loan of another Type, provided that (i) subject to the further proviso at the end of this §2.5(a) and subject to §2.5(b) and §2.5(d), with respect to any conversion of a Base Rate Loan to a Libor Rate Loan (or a continuation of a Libor Rate Loan, as provided in §2.5(b)), the Borrower shall give the Agent (with copies to the

Agent for each Lender) at least three (3) Business Days’ prior written notice of such election, which such notice must be received by the Agent by 10:00 a.m. on any Business Day; and (ii) no Loan may be converted into a Libor Rate Loan when any Default or Event of Default has occurred and is continuing. All or any part of outstanding Term Loan of any Type may be converted as provided herein, provided that each Conversion Request relating to the conversion of a Base Rate Loan to a Libor Rate Loan shall be for an amount equal to $1,000,000 or an integral multiple of $100,000 in excess thereof and shall be irrevocable by the Borrower.

(b) Any portion of the Term Loan of any Type may be continued as such upon the expiration of the Interest Period with respect thereto (i) in the case of Base Rate Loans, automatically and (ii) in the case of Libor Rate Loans by compliance by the Borrower with the notice provisions contained in §2.5(a)(i); provided that no Libor Rate Loan may be continued as such when any Default or Event of Default has occurred and is continuing but shall be automatically converted to a Base Rate Loan on the last day of the first Interest Period relating thereto ending during the continuance of any Default or Event of Default. The Borrower shall notify the Agent promptly when any such automatic conversion contemplated by this §2.5(b) is scheduled to occur.

(c) In the event that the Borrower does not notify the Agent of its election hereunder with respect to any portion of the Term Loan in accordance with the terms hereof, such Loan shall be automatically converted to a Base Rate Loan at the end of the applicable Interest Period.

(d) The Borrower may not request or elect a Libor Rate Loan pursuant to §2.4, elect to convert a Base Rate Loan to a Libor Rate Loan pursuant to §2.5(a) or elect to continue a Libor Rate Loan pursuant to §2.5(b) if, after giving effect thereto, there would be greater than six (6) Libor Rate Loans then outstanding. Any Conversion Request for a Libor Rate Loan that would create greater than six (6) Libor Rate Loans outstanding shall be deemed to be a Conversion Request for a Base Rate Loan. By way of explanation of the foregoing, in the event that the Borrower wishes to convert or continue two or more Loans into one Libor Rate Loan on the same day and for identical Interest Periods, such Libor Rate Loan shall constitute one single Libor Rate Loan for purposes of this clause (d).

§2.6. Funds for the Term Loan.

(a) Subject to the other provisions of this §2, on the Closing Date, each of the Lenders will make available to the Agent, at the Agent’s Head Office, in immediately available funds, the amount of such Lender’s Commitment Percentage of the Term Loan. Upon receipt from each Lender of such amount, the Agent will make available to the Borrower the aggregate amount of such Term Loan made available to the Agent by the Lenders. The failure or refusal of any Lender to make available to the Agent at the aforesaid time and place on the Closing Date the amount of its Commitment Percentage of the Term Loan shall not relieve any other Lender from its several obligation

hereunder to make available to the Agent the amount of its Commitment Percentage of any Term Loan but in no event shall the Agent (in its capacity as Agent) have any obligation to make any funding or shall any Lender be obligated to fund more than its Commitment Percentage of the Term Loan or to increase its Commitment Percentage on account of such failure or otherwise.

(b) The Agent may, unless notified to the contrary by any Lender prior to the Closing Date, assume that such Lender has made available to the Agent on the Closing Date the amount of such Lender’s Commitment Percentage of the Term Loan, and the Agent may (but it shall not be required to), in reliance upon such assumption, make available to the Borrower a corresponding amount. If any Lender makes available to the Agent such amount after the Closing Date, such Lender shall pay to the Agent on demand an amount equal to the product of (i) the average, computed for the period referred to in clause (iii) below, of the weighted average interest rate paid by the Agent for federal funds acquired by the Agent during each day included in such period, multiplied by (ii) the amount of such Lender’s Commitment Percentage of the Term Loan, multiplied by (iii) a fraction, the numerator of which is the number of days that elapsed from and including the Closing Date to the date on which the amount of such Lender’s Commitment Percentage of the Term Loan shall become immediately available to the Agent, and the denominator of which is 365. A statement of the Agent submitted to such Lender with respect to any amounts owing under this paragraph shall be prima facie evidence of the amount due and owing to the Agent by such Lender.

§3.2. Optional Repayments of the Term Loan. The Borrower shall have the right, at its election, to prepay the outstanding amount of the Term Loan, in whole or in part, at any time without penalty or premium; provided that the outstanding amount of any Libor Rate Loans may not be prepaid on a date other than the last day of an Interest Period unless the Borrower pays the Libor Breakage Costs for each Libor Rate Loan so prepaid at the time of such prepayment. The Borrower shall give the Agent (with copies to the Agent for each Lender), no later than 10:00 a.m., Cleveland, Ohio time, at least two (2) Business Days’ prior written notice of any prepayment pursuant to this §3.2 of any Base Rate Loans, and at least four (4) Business Days’ notice of any proposed prepayment pursuant to this §3.2 of Libor Rate Loans, specifying the proposed date of prepayment and the principal amount to be prepaid.

§4. CERTAIN GENERAL PROVISIONS.

§4.1. Funds for Payments.

(a) All payments of principal, interest, fees, and any other amounts due hereunder or under any of the other Loan Documents shall be made to the Agent, for the respective accounts of the Lenders or (as the case may be) the Agent, at the Agent’s Head Office, in each case in Dollars and in immediately available funds. The Borrower shall make each payment of principal of and interest on the Term Loan and of fees hereunder or thereunder not later than 12:00 p.m. (Cleveland, Ohio time) on the due date thereof.

(b) All payments by the Borrower hereunder and under any of the other Loan Documents shall be made without setoff or counterclaim and free and clear of and without deduction for any taxes, levies, imposts, duties, charges, fees, deductions, withholdings, compulsory liens, restrictions or conditions of any nature now or hereafter imposed or levied by any jurisdiction or any political subdivision thereof or taxing or other authority therein unless the Borrower is compelled by law to make such deduction or withholding. If the Borrower is compelled by law to make any such deduction or withholding with respect to any amount payable by it hereunder or under any of the other Loan Documents (except with respect to taxes on the income or profits of the Agent or any Lender), the Borrower shall pay to the Agent, for the account of the Lenders or (as the case may be) the Agent, on the date on which such amount is due and payable hereunder or under such other Loan Document, such additional amount in Dollars as shall be necessary to enable the Lenders to receive the same net amount which the Lenders would

have received on such due date had no such deduction or withholding obligation been imposed upon the Borrower. The Borrower will deliver promptly to the Agent (with copies to the Agent for each Lender) certificates or other valid vouchers for all taxes or other charges deducted from or paid with respect to payments made by the Borrower hereunder or under such other Loan Document.

§4.2. Computations. All computations of interest on the Term Loan and of fees to the extent applicable shall be based on a 360-day year, in each case paid for the actual number of days elapsed. Except as otherwise provided in the definition of the term “Interest Period” with respect to Libor Rate Loans, whenever a payment hereunder or under any of the other Loan Documents becomes due on a day that is not a Business Day, the due date for such payment shall be extended to the next succeeding Business Day, and interest shall accrue during such extension. The outstanding amount of the Loans as reflected on the Note Records or record attached to any other Note from time to time shall constitute prima facie evidence of the principal amount thereof.

§4.3. Inability to Determine Libor Rate. In the event, prior to the commencement of any Interest Period relating to any Libor Rate Loan, the Agent shall determine that adequate and reasonable methods do not exist for ascertaining the Libor Rate that would otherwise determine the rate of interest to be applicable to any Libor Rate Loan during any Interest Period, the Agent shall forthwith give notice of such determination (which shall be conclusive and binding on the Borrower) to the Borrower and the Lenders. In such event (a) each Libor Rate Loan will automatically, on the last day of the then current Interest Period applicable thereto, become a Base Rate Loan, and (b) the obligations of the Lenders to make Libor Rate Loans shall be suspended, in each case unless and until the Agent determines that the circumstances giving rise to such suspension no longer exist, whereupon the Agent shall so notify the Borrower and the Lenders.

§4.4. Illegality. Notwithstanding any other provisions herein, if any present or future law, regulation, treaty or directive or in the interpretation or application thereof shall make it unlawful for any Lender to make or maintain Libor Rate Loans, such Lender shall forthwith give notice of such circumstances to the Agent and the Borrower and thereupon (a) the Commitment of such Lender to make Libor Rate Loans or convert Base Rate Loans to Libor Rate Loans shall forthwith be suspended and (b) such Lender’s Commitment Percentage of Libor Rate Loans then outstanding shall be converted automatically to Base Rate Loans on the last day of each Interest Period applicable to such Libor Rate Loans or within such earlier period as may be required by law, all until such time as it is no longer unlawful for such Lender to make or maintain Libor Rate Loans. The Borrower hereby agrees promptly to pay the Agent for the account of such Lender, upon demand, any additional amounts necessary to compensate such Lender for Libor Breakage Costs incurred by such Lender in making any conversion required by this §4.4 prior to the last day of an Interest Period.

§4.5. Additional Costs, Etc. If any present or future applicable law, which expression, as used herein, includes statutes, rules and regulations thereunder and interpretations thereof by any competent court or by any governmental or other regulatory body or official charged with the administration or the interpretation thereof and requests, directives, instructions and notices at any time or from time to time hereafter made upon or otherwise issued to any Lender or the Agent by any central bank or other fiscal, monetary or other authority (whether or not having the force of law, but if not having the force of law, then generally applied by the Lenders or the Agent with respect to similar loans), shall:

(a) subject any Lender or the Agent to any tax, levy, impost, duty, charge, fee, deduction or withholding of any nature with respect to this Agreement, the other Loan Documents, such Lender’s Commitment or the Term Loan (other than taxes based upon or measured by the income or profits of such Lender or the Agent), or

(b) change the basis of taxation (except for changes in taxes on income or profits) of payments to any Lender of the principal of or the interest on the Term Loan or any other amounts payable to the Agent or any Lender under this Agreement or the other Loan Documents, or

(c) impose or increase or render applicable (other than to the extent specifically provided for elsewhere in this Agreement) any special deposit, reserve, assessment, liquidity, capital adequacy or other similar requirements (whether or not having the force of law) against assets held by, or deposits in or for the account of, or loans by, or letters of credit issued by, or commitments of an office of any Lender, or

(d) impose on any Lender or the Agent any other conditions or requirements with respect to this Agreement, the other Loan Documents, the Term Loan, such Lender’s Commitment, or any class of loans or commitments of which any portion of the Term Loan or such Lender’s Commitment forms a part;

and the result of any of the foregoing is


	(i) to increase the cost to any Lender of making, funding, issuing, renewing, extending or maintaining any of the Term Loan or such Lender’s Commitment, or

	(ii) to reduce the amount of principal, interest or other amount payable to such Lender or the Agent hereunder on account of such Lender’s Commitment or the Term Loan, or

	(iii) to require such Lender or the Agent to make any payment or to forego any interest or other sum payable hereunder, the amount of which payment or foregone interest or other sum is calculated by reference


	to the gross amount of any sum receivable or deemed received by such Lender or the Agent from the Borrower hereunder,

then, and in each such case, the Borrower will, upon demand made by the Agent or such Lender (such demand to be made promptly by the Agent or such Lender upon the making of any such determination), at any time and from time to time and as often as the occasion therefor may arise, pay to such Lender or the Agent such additional amounts as such Lender or the Agent shall determine in good faith to be sufficient to compensate such Lender or the Agent for such additional cost, reduction, payment or foregone interest or other sum, provided that such Lender or the Agent is generally imposing similar charges on its other similarly situated borrowers. The Agent shall provide the Borrower with a calculation, in reasonable detail, of such amounts in accordance with its customary practices.

§4.6. Capital Adequacy. If any future law, governmental rule, regulation, policy, guideline or directive (whether or not having the force of law, but if not having the force of law, then generally applied by the Lenders with respect to similar loans) or the interpretation thereof by a court or governmental authority with appropriate jurisdiction affects the amount of capital required or expected to be maintained by banks or bank holding companies and any Lender or the Agent determines that the amount of capital required to be maintained by it is increased by or based upon the existence of the Term Loan made pursuant hereto, then such Lender or the Agent may notify the Borrower of such fact, and the Borrower shall pay to such Lender or the Agent from time to time, upon demand made by the Agent or such Lender (such demand to be made promptly by the Agent or such Lender upon the making of any such determination), as an additional fee payable hereunder, such amount as such Lender or the Agent shall determine reasonably and in good faith and certify in a notice to the Borrower to be an amount that will adequately compensate such Lender in light of these circumstances for its increased costs of maintaining such capital. Each Lender and the Agent shall allocate such cost increases among its customers in good faith and on an equitable basis, and will not charge the Borrower unless it is generally imposing a similar charge on its other similarly situated borrowers. The Agent shall provide the Borrower with a calculation, in reasonable detail, of such amounts in accordance with its customary practices.

§4.7. Certificate; Limitations. A certificate setting forth any additional amounts payable pursuant to §§4.5 or 4.6 and a brief explanation of such amounts which are due, submitted by any Lender or the Agent to the Borrower, shall be prima facie evidence that such amounts are due and owing. Notwithstanding anything to the contrary contained in this Article 5, to the extent reasonably possible, each Lender shall designate an alternate lending office in the continental United States to make the Loans in order to reduce any liability of Borrower to such Lender under §§4.4, 4.5 or 4.6 or to avoid the unavailability of a Libor Rate Loan, so long as such designation is not disadvantageous to such Lender.

§4.8. Indemnity. In addition to the other provisions of this Agreement regarding such matters, the Borrower agrees to indemnify the Agent and each Lender and to hold

the Agent and each Lender harmless from and against any loss, cost or expense (including loss of anticipated profits) that the Agent or such Lender may sustain or incur as a consequence of (a) a default by the Borrower in the payment of any principal amount of or any interest on any Libor Rate Loans as and when due and payable, including any such loss or expense arising from interest or fees payable by the Agent or such Lender to lenders of funds obtained by it in order to maintain its Libor Rate Loans, (b) the failure by the Borrower to make a borrowing or conversion after the Borrower has given a Completed Loan Request for a Libor Rate Loan or a Conversion Request for a Libor Rate Loan, and (c) the making of any payment of a Libor Rate Loan or the making of any conversion of any such Loan to a Base Rate Loan on a day that is not the last day of the applicable Interest Period with respect thereto, including interest or fees payable by the Agent or a Lender to lenders of funds obtained by it in order to maintain any such Libor Rate Loans.

§4.9. Interest on Overdue Amounts; Late Charge. Notwithstanding anything to the contrary stated herein, upon the occurrence and during the continuance of an Event of Default, at the option of the Majority Lenders, to the extent permitted by applicable law, the unpaid balance of all Obligations shall bear interest at the rate otherwise applicable thereto plus 2%, compounded daily until such Event of Default is cured or waived to the satisfaction of the Agent and the required Lenders. In addition, the Borrower shall pay a late charge equal to five percent (5%) of any amount of interest charges on the Term Loan which is not paid within ten (10) days of the date when due.

§14.2. Reserved.

§14.3. Remedies. In the event that one or more Events of Default shall have occurred and be continuing, whether or not the Lenders shall have accelerated the maturity of the Loans pursuant to §14.1, the Majority Lenders may direct the Agent to proceed to protect and enforce the rights and remedies of the Agent and the Lenders under this Agreement, the Notes, any or all of the other Loan Documents or under applicable law by suit in equity, action at law or other appropriate proceeding (including for the specific performance of any covenant or agreement contained in this Agreement or the other Loan Documents or any instrument pursuant to which the Obligations are evidenced and, to the full extent permitted by applicable law, the obtaining of the ex parte appointment of a receiver), and, if any amount shall have become due, by declaration or otherwise, proceed to enforce the payment thereof or any other legal or equitable right or remedy of the Agent and the Lenders under the Loan Documents or applicable law. No remedy herein conferred upon the Lenders or the Agent or the holder of any Note is intended to be exclusive of any other remedy and each and every remedy shall be cumulative and shall be in addition to every other remedy given hereunder or under any of the other Loan Documents or now or hereafter existing at law or in equity or by statute or any other provision of law.

§15. SECURITY INTEREST AND SET-OFF.

§15.1 Security Interest. Borrower hereby grants to the Agent, on behalf of and for the benefit of the Lenders, and to each Lender, a lien, security interest and right of

setoff as security for all liabilities and obligations to the Lenders, whether now existing or hereafter arising, upon and against all deposits, credits, collateral and property, now or hereafter in the possession, custody, safekeeping or control of the Agent or any Lender or any entity under the control of KeyCorp. and its successors and assigns, or in transit to any of them.

§15.2 Set-Off and Debit. (i) If any Event of Default or other event which would entitle the Agent to accelerate the Loans occurs, or (ii) at any time, whether or not any Default or Event of Default exists, in the event any attachment, trustee process, garnishment, or other levy or lien is, or is sought to be, imposed on any property of the Borrower; then, in any such event, any such deposits, balances or other sums credited by or due from the Agent or any Lender, or from any such affiliate of the Agent or any Lender, to the Borrower may to the fullest extent not prohibited by applicable law at any time or from time to time, without regard to the existence, sufficiency or adequacy of any other collateral, and without notice or compliance with any other condition precedent now or hereafter imposed by statute, rule of law or otherwise, all of which are hereby waived, be set off, debited and appropriated, and applied by the Agent or any Lender, as the case may be, against any or all of the Obligations irrespective of whether demand shall have been made and although such Obligations may be unmatured, in such manner as the Agent or the applicable Lender in its sole and absolute discretion may determine. Within five (5) Business Days of making any such set off, debit or appropriation and application, the Agent agrees to endeavor to notify the Borrower thereof, provided that the failure to give such notice shall not affect the validity of such set off, debit or appropriation and application. ANY AND ALL RIGHTS TO REQUIRE THE AGENT OR ANY LENDER TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE LOANS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF THE BORROWER, ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED. Each of the Lenders agrees with each other Lender that (a) if an amount to be set off is to be applied to indebtedness of the Borrower to such Lender, other than the obligations evidenced by the Note held by such Lender, such amount shall be applied ratably to such other indebtedness and to the obligations evidenced by the Note held by such Lender, and (b) if such Lender shall receive from the Borrower, whether by voluntary payment, exercise of the right of setoff, counterclaim, cross action, enforcement of the claim evidenced by the Note held by such Lender by proceedings against the Borrower at law or in equity or by proof thereof in bankruptcy, reorganization liquidation, receivership or similar proceedings, or otherwise, and shall retain and apply to the payment of the Note held by such Lender any amount in excess of its ratable portion of the payments received by all of the Lenders with respect to the Note held by all of the Lenders, such Lender will make such disposition and arrangements with the other Lenders with respect to such excess, either by way of distribution, pro tanto assignment of claims, subrogation or otherwise as shall result in each Lender receiving in respect of the Note held by it its proportionate payment as contemplated by this Agreement; provided that if all or any part of such excess payment is thereafter recovered

from such Lender, such disposition and arrangements shall be rescinded and the amount restored to the extent of such recovery, but without interest.

§15.3 Right to Freeze. The Agent and each of the Lenders shall also have the right, at its option, upon the occurrence of any event which would entitle the Agent or any Lender to set off or debit as set forth in §15.2, to freeze, block or segregate any such deposits, balances and other sums so that the Borrower may not access, control or draw upon the same.

§15.4 Additional Rights. The rights of the Agent, the Lenders and each affiliate of Administrative Agent and each of the Lenders under this §15 are in addition to, and not in limitation of, other rights and remedies, including other rights of set off, which the Agent or any Lender may have.

§16. THE AGENT.

§16.1. Authorization. (a) The Agent is authorized to take such action on behalf of each of the Lenders and to exercise all such powers as are hereunder and under any of the other Loan Documents and any related documents delegated to the Agent, together with such powers as are reasonably incident thereto, provided that no duties or responsibilities not expressly assumed herein or therein shall be implied to have been assumed by the Agent. The relationship between the Agent and the Lenders is and shall be that of agent and principal only, and nothing contained in this Agreement or any of the other Loan Documents shall be construed to constitute the Agent as a trustee or fiduciary for any Lender.

(b) The Borrower, without further inquiry or investigation, shall, and is hereby authorized by the Lenders to, assume that all actions taken by the Agent hereunder and in connection with or under the Loan Documents are duly authorized by the Lenders. The Lenders shall notify Borrower of any successor to Agent by a writing signed by Majority Lenders, which successor shall be reasonably acceptable to the Borrower so long as no Default or Event of Default has occurred and is continuing. The Borrower acknowledges that any lender that acquires KeyBank is acceptable as a successor to the Agent.

§16.2. Employees and Agents. The Agent may exercise its powers and execute its duties by or through employees or agents and shall be entitled to take, and to rely on, advice of counsel concerning all matters pertaining to its rights and duties under this Agreement and the other Loan Documents. The Agent may utilize the services of such Persons as the Agent in its sole discretion may reasonably determine, and all reasonable fees and expenses of any such Persons shall be paid by the Borrower.

§16.3. No Liability. Neither the Agent, nor any of its shareholders, directors, officers or employees nor any other Person assisting them in their duties nor any agent or employee thereof, shall be liable for any waiver, consent or approval given or any action

taken, or omitted to be taken, in good faith by it or them hereunder or under any of the other Loan Documents, or in connection herewith or therewith, or be responsible for the consequences of any oversight or error of judgment whatsoever, except that the Agent may be liable for losses due to its willful misconduct or gross negligence, as finally determined by a court of competent jurisdiction.

§16.4. No Representations. The Agent shall not be responsible for the execution or validity or enforceability of this Agreement, the Notes or any of the other Loan Documents or for the validity, enforceability or collectibility of any such amounts owing with respect to the Notes, or for any recitals or statements, warranties or representations made herein or in any of the other Loan Documents or in any certificate or instrument hereafter furnished to it by or on behalf of the Trust or the Borrower or any of their respective Subsidiaries, or be bound to ascertain or inquire as to the performance or observance of any of the terms, conditions, covenants or agreements in this Agreement or the other Loan Documents. The Agent shall not be bound to ascertain whether any notice, consent, waiver or request delivered to it by the Borrower or the Trust or any holder of any of the Notes shall have been duly authorized or is true, accurate and complete. The Agent has not made nor does it now make any representations or warranties, express or implied, nor does it assume any liability to the Lenders, with respect to the credit worthiness or financial condition of the Borrower or any of its Subsidiaries or the Trust or any of the Subsidiaries or any tenant under a Lease or any other entity. Each Lender acknowledges that it has, independently and without reliance upon the Agent or any other Lender, and based upon such information and documents as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement.

§16.5. Payments.

(a) A payment by the Borrower to the Agent hereunder or any of the other Loan Documents for the account of any Lender shall constitute a payment to such Lender. The Agent agrees to distribute to each Lender such Lender’s pro rata share of payments received by the Agent for the accounts of all the Lenders, as provided herein or in any of the other Loan Documents. All such payments shall be made on the date received, if before 1:00 p.m., and if after 1:00 p.m., on the next Business Day. If payment is not made on the day received, the funds shall be invested by the Agent in overnight obligations, and interest thereon paid pro rata to the Lenders.

(b) If in the reasonable opinion of the Agent the distribution of any amount received by it in such capacity hereunder, under the Notes or under any of the other Loan Documents might involve it in material liability, it may refrain from making distribution until its right to make distribution shall have been adjudicated by a court of competent jurisdiction, provided that the Agent shall invest any such undistributed amounts in overnight obligations on behalf of the Lenders and interest thereon shall be paid pro rata to the Lenders. If a court of competent jurisdiction shall adjudge that any amount received and distributed by the Agent is to be repaid, each Person to whom any

such distribution shall have been made shall either repay to the Agent its proportionate share of the amount so adjudged to be repaid or shall pay over the same in such manner and to such Persons as shall be determined by such court.

(c) Notwithstanding anything to the contrary contained in this Agreement or any of the other Loan Documents, any Lender that fails to adjust promptly such Lender’s outstanding principal and its pro rata Commitment Percentage as provided in §2.1, shall be deemed delinquent (a “Delinquent Lender”) and shall be deemed a Delinquent Lender until such time as such delinquency is satisfied. A Delinquent Lender shall be deemed to have assigned any and all payments due to it from the Borrower, whether on account of outstanding Loans, interest, fees or otherwise, to the remaining nondelinquent Lenders for application to, and reduction of, their respective pro rata shares of all outstanding Loans. The Delinquent Lender hereby authorizes the Agent to distribute such payments to the nondelinquent Lenders in proportion to their respective pro rata shares of all outstanding Loans. If not previously satisfied directly by the Delinquent Lender, a Delinquent Lender shall be deemed to have satisfied in full a delinquency when and if, as a result of application of the assigned payments to all outstanding Loans of the nondelinquent Lenders, the Lenders’ respective pro rata shares of all outstanding Loans have returned to those in effect immediately prior to such delinquency and without giving effect to the nonpayment causing such delinquency.

§16.6. Holders of Notes. The Agent may deem and treat the payee of any Notes as the absolute owner thereof for all purposes hereof until it shall have been furnished in writing with a different name by such payee or by a subsequent holder, assignee or transferee.

§16.7. Indemnity. The Lenders ratably and severally agree hereby to indemnify and hold harmless the Agent and its Affiliates from and against any and all claims, actions and suits (whether groundless or otherwise), losses, damages, costs, expenses (including any expenses for which the Agent has not been reimbursed by the Borrower as required by §17), and liabilities of every nature and character arising out of or related to this Agreement, the Notes, or any of the other Loan Documents or the transactions contemplated or evidenced hereby or thereby, or the Agent’s actions taken hereunder or thereunder, except to the extent that any of the same shall be directly caused by the Agent’s willful misconduct or gross negligence, as finally determined by a court of competent jurisdiction.

§16.8. Agent as Lender. In its individual capacity as a Lender, KeyBank shall have the same obligations and the same rights, powers and privileges in respect to its Commitment and the Term Loan made by it, and as the holder of any of the Notes, as it would have were it not also the Agent.

§16.9. Notification of Defaults and Events of Default. Each Lender hereby agrees that, upon learning of the existence of a Default or an Event of Default, it shall (to the extent notice has not previously been provided) promptly notify the Agent thereof.

The Agent hereby agrees that upon receipt of any notice under this §16.9 it shall promptly notify the other Lenders of the existence of such Default or Event of Default.

§16.10. Duties in Case of Enforcement. In the case one or more Events of Default have occurred and shall be continuing, and whether or not acceleration of the Obligations shall have occurred, the Agent shall, at the request, or may, upon the consent, of the Majority Lenders, and provided that the Lenders have given to the Agent such additional indemnities and assurances against expenses and liabilities as the Agent may reasonably request, proceed to enforce the provisions of this Loan Agreement and the other Loan Documents and the exercise of any other legal or equitable rights or remedies as it may have hereunder or under any other Loan Document or otherwise by virtue of applicable law, or to refrain from so acting if similarly requested by the Majority Lenders. The Agent shall be fully protected in so acting or refraining from acting upon the instruction of the Majority Lenders, and such instruction shall be binding upon all the Lenders. The Majority Lenders may direct the Agent in writing as to the method and the extent of any such foreclosure, sale or other disposition or the exercise of any other right or remedy, the Lenders hereby agreeing to severally indemnify and hold the Agent harmless from all costs and liabilities incurred in respect of all actions taken or omitted in accordance with such direction, provided that the Agent need not comply with any such direction to the extent that the Agent reasonably believes the Agent’s compliance with such direction to be unlawful or commercially unreasonable in any applicable jurisdiction. The Agent may, in its discretion but without obligation, in the absence of direction from the Majority Lenders, take such interim actions as it believes reasonably necessary to preserve the rights of the Lenders hereunder, including but not limited to petitioning a court for injunctive relief or appointment of a receiver. Each of the Lenders acknowledges and agrees that no individual Lender may separately enforce or exercise any of the provisions of any of the Loan Documents, including without limitation the Notes, other than through the Agent. The Agent shall advise the Lenders of all such action taken by the Agent.

§16.11. Successor Agent. KeyBank, or any successor Agent, may resign as Agent at any time by giving at least thirty (30) days prior written notice thereof to the Lenders and to the Borrower. Any such resignation shall be effective upon appointment and acceptance of a successor Agent, as hereinafter provided. Upon any such resignation, the Majority Lenders shall have the right to appoint a successor Agent, which is a Lender under this Agreement, provided that so long as no Default or Event of Default has occurred and is continuing the Borrower shall have the right to approve any successor Agent, which approval shall not be unreasonably withheld. If, in the case of a resignation by the Agent, no successor Agent shall have been so appointed by the Majority Lenders and approved by the Borrower, and shall have accepted such appointment, within thirty (30) days after the retiring Agent’s giving of notice of resignation, then the retiring Agent may, on behalf of the Lenders, appoint any one of the other Lenders as a successor Agent. The Borrower acknowledges that any lender that acquires KeyBank is acceptable as a successor Agent. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested

with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from all further duties and obligations as Agent under this Agreement. After any Agent’s resignation hereunder as Agent, the provisions of this §16 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement. The Agent may be removed at the direction of the Majority Lenders in the event of a final judicial determination (in which the Agent had an opportunity to be heard) by a court of competent jurisdiction that the Agent had acted in a grossly negligent manner or in willful misconduct.

§16.12. Notices. Any notices or other information required hereunder to be provided to the Agent (with copies to the Agent for each Lender) shall be forwarded by the Agent to each of the Lenders promptly.

§16.13. Reserved.

§17. EXPENSES. The Borrower agrees to pay (a) the reasonable costs of producing and reproducing this Agreement, the other Loan Documents and the other agreements and instruments mentioned herein, (b) the reasonable fees, expenses and disbursements of the Agent’s outside counsel or any local counsel to the Agent incurred in connection with the preparation, administration or interpretation of the Loan Documents and other instruments mentioned herein, each closing hereunder, and amendments, modifications, approvals, consents or waivers hereto or hereunder, (c) the fees, expenses and disbursements of the Agent incurred by the Agent in connection with the preparation, administration or interpretation of the Loan Documents and other instruments mentioned herein, including, without limitation, the costs incurred by the Agent in connection with its inspection of the Project, and, without double-counting amounts under clause (b) above, the fees and disbursements of the Agent’s counsel in preparing the documentation, (d) all, if any, title insurance premiums, appraisal fees, engineer’s, inspector’s and surveyor’s fees, (e) the fees, costs, expenses and disbursements of the Agent and its Affiliates incurred in connection with the syndication and/or participations of the Loans (whether occurring before or after the closing hereunder), including, without limitation, reasonable legal fees, travel costs, costs of preparing syndication materials and photocopying costs, (f) all reasonable expenses (including reasonable attorneys’ fees and costs, which attorneys may be employees of any Lender or the Agent, and the fees and costs of engineers, appraisers, surveyors, investment bankers, or other experts retained by any Lender or the Agent in connection with any such enforcement proceedings) incurred by any Lender or the Agent in connection with (i) the enforcement of or preservation of rights under any of the Loan Documents against the Borrower or any of its Subsidiaries or the Trust or the administration thereof after the occurrence and during the continuance of a Default or Event of Default (including, without limitation, expenses incurred in any restructuring and/or “workout” of the Loans), and (ii) any litigation, proceeding or dispute whether arising hereunder or otherwise, in any way related to any Lender’s or the Agent’s relationship with the Borrower or any of its Subsidiaries or the Trust, (g) all reasonable fees, expenses and disbursements of the Agent incurred in connection with UCC searches and filings, UCC terminations or mortgage discharges, and the like, and (h) all costs

incurred by the Agent in the future in connection with its inspection of the Project. The covenants of this §17 shall survive the repayment of the amounts owing under the Notes and this Agreement and the termination of this Agreement and the obligations of the Lenders hereunder.

§18. INDEMNIFICATION. The Borrower agrees to indemnify and hold harmless the Agent and each of the Lenders and the shareholders, directors, agents, officers, subsidiaries and affiliates of the Agent and each of the Lenders from and against any and all claims, actions and suits, whether groundless or otherwise, and from and against any and all liabilities, losses (including amounts, if any, owing to any Lender pursuant to §§4.4, 4.5, 4.6 and 4.8), settlement payments, obligations, damages and expenses of every nature and character in connection therewith, arising out of this Agreement or any of the other Loan Documents or the transactions contemplated hereby or thereby or which otherwise arise in connection with the financing, including, without limitation, (a) any actual or proposed use by the Borrower or any of its Subsidiaries of the proceeds of any of the Loans, (b) the Borrower or any of its Subsidiaries entering into or performing this Agreement or any of the other Loan Documents, or (c) pursuant to §8.16, in each case including, without limitation, the reasonable fees and disbursements of counsel and allocated costs of internal counsel incurred in connection with any such investigation, litigation or other proceeding, provided, however, that the Borrower shall not be obligated under this §18 to indemnify any Person for liabilities arising from such Person’s own gross negligence or willful misconduct, as finally determined by a court of competent jurisdiction. In litigation, or the preparation therefor, the Borrower shall be entitled to select counsel reasonably acceptable to the Majority Lenders, and the Agent (as approved by the Majority Lenders) shall be entitled to select their own supervisory counsel, and, in addition to the foregoing indemnity, the Borrower agrees to pay promptly the reasonable fees and expenses of each such counsel. If and to the extent that the obligations of the Borrower under this §18 are unenforceable for any reason, the Borrower hereby agrees to make the maximum contribution to the payment in satisfaction of such obligations which is permissible under applicable law. The provisions of this §18 shall survive the repayment of the amounts owing under the Notes and this Agreement and the termination of this Agreement and the obligations of the Lenders hereunder and shall continue in full force and effect as long as the possibility of any such claim, action, cause of action or suit exists.

§19. SURVIVAL OF COVENANTS, ETC. All covenants, agreements, representations and warranties made herein, in the Notes, in any of the other Loan Documents or in any documents or other papers delivered by or on behalf of the Borrower or any of its Subsidiaries or the Trust pursuant hereto shall be deemed to have been relied upon by the Lenders and the Agent, notwithstanding any investigation heretofore or hereafter made by any of them, and shall survive the making by the Lenders of any of the Loans, as herein contemplated, and shall continue in full force and effect so long as any amount due under this Agreement or the Notes or any of the other Loan Documents remains outstanding. The indemnification obligations of the Borrower provided herein and in the other Loan Documents shall survive the full repayment of amounts due and the

termination of the obligations of the Lenders hereunder and thereunder to the extent provided herein and therein. All statements contained in any certificate or other paper delivered to any Lender or the Agent at any time by or on behalf of the Borrower or any of its Subsidiaries or the Trust pursuant hereto or in connection with the transactions contemplated hereby shall constitute representations and warranties by the Borrower or such Subsidiary or the Trust hereunder.

§20. ASSIGNMENT; PARTICIPATIONS; ETC.

§20.1. Conditions to Assignment by Lenders. Except as provided herein, each Lender may assign to one or more Eligible Assignees (or to any other financial institution approved by the Agent) all or a portion (in a minimum amount of $1,000,000) of its interests, rights and obligations under this Agreement (including all or a portion of its Commitment Percentage and Commitment and the same portion of the Loans at the time owing to it, the Notes held by it); provided that (a) the Agent and, other than during an Event of Default, the Borrower each shall have the right to approve any Eligible Assignee (or such other financial institution), which approval, in the case of an Eligible Assignee, shall not be unreasonably withheld or delayed, (b) subject to the provisions of §2.7, each Lender shall have at all times an amount of its Commitment of not less than $1,000,000 unless otherwise consented to by the Agent and (c) the parties to such assignment shall execute and deliver to the Agent, for recording in the Register (as hereinafter defined), an assignment and assumption, substantially in the form of Exhibit D hereto (an “Assignment and Assumption”), together with any Notes subject to such assignment.

Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement, the other Loan Documents or any other instrument or document furnished pursuant hereto; (b) the assigning Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower and its Subsidiaries or the Trust or any other Person primarily or secondarily liable in respect of any of the Obligations, or the performance or observance by the Borrower and its Subsidiaries or the Trust or any other Person primarily or secondarily liable in respect of any of the Obligations of any of their obligations under this Agreement or any of the other Loan Documents or any other instrument or document furnished pursuant hereto or thereto; (c) such assignee confirms that it has received a copy of this Agreement, together with copies of the most recent financial statements referred to in §7.4 and §8.4 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Assumption; (d) such assignee will, independently and without reliance upon the assigning Lender, the Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (e) such assignee represents and warrants that it is an Eligible Assignee (unless otherwise approved by the Agent); (f) such assignee appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers under this Agreement and the other Loan Documents as are delegated to the Agent by the terms hereof or thereof, together with such powers as are reasonably incidental thereto; (g) such assignee agrees that it will perform in accordance with their terms all of the obligations that by the terms of this Agreement are required to be performed by it as a Lender; and (h) such assignee represents and warrants that it is legally authorized to enter into such Assignment and Assumption.

§20.3. Register. The Agent shall maintain a copy of each Assignment and Assumption delivered to it and a register or similar list (the “Register”) for the recordation of the names and addresses of the Lenders and the Commitment Percentages of, and principal amount of the Loans owing to, the Lenders from time to time. The entries in the Register shall be conclusive, in the absence of manifest error, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower and the Lenders at any reasonable time and from time to time upon reasonable prior notice. Upon each such recordation, the assigning Lender agrees to pay to the Agent a registration fee in the sum of $3,500 and all legal fees and expenses incurred by the Agent in connection with such assignment.

§20.4. New Notes. Upon its receipt of an Assignment and Assumption executed by the parties to such assignment, together with each Note subject to such assignment, the Agent shall (a) record the information contained therein in the Register, and (b) give prompt notice thereof to the Borrower and the Lenders (other than the assigning Lender). Unless done simultaneously with the Assignment and Assumption, within three (3)

Business Days after receipt of such notice, the Borrower, at its own expense, shall execute and deliver to the Agent, in exchange for each surrendered Note, a new Note to the order of such Eligible Assignee in an amount equal to the amount assumed by such Eligible Assignee pursuant to such Assignment and Assumption and, if the assigning Lender has retained some portion of its obligations hereunder, a new Note and other Note, if applicable, to the order of the assigning Lender in an amount equal to the amount retained by it hereunder. Such new Notes shall provide that they are replacements for the surrendered Notes, shall be in an aggregate principal amount equal to the aggregate principal amount of the surrendered Notes, shall be dated the effective date of such Assignment and Assumption and shall otherwise be in substantially the form of the assigned Notes. The surrendered Notes shall be canceled and returned to the Borrower.

§20.5. Participations. Each Lender may sell participations to one or more lending institutions or other entities in all or a portion of such Lender’s rights and obligations under this Agreement and the other Loan Documents; provided that (a) each such participation shall be in an amount of not less than $1,000,000, (b) any such sale or participation shall not affect the rights and duties of the selling Lender hereunder to the Borrower and the Agent and the Lender shall continue to exercise all approvals, disapprovals and other functions of a Lender, (c) the only rights granted to the participant pursuant to such participation arrangements with respect to waivers, amendments or modifications of, or approvals under, the Loan Documents shall be the rights to approve waivers, amendments or modifications that would reduce the principal of or the interest rate on any Loans, extend the term or increase the amount of the Commitment of such Lender as it relates to such participant, reduce the amount of any fees to which such participant is entitled or extend any regularly scheduled payment date for principal or interest, and (d) no participant shall have the right to grant further participations or assign its rights, obligations or interests under such participation to other Persons without the prior written consent of the Agent, which consent shall not be unreasonably withheld.

§20.6. Pledge by Lender. Notwithstanding any other provision of this Agreement, any Lender at no cost to the Borrower may at any time pledge all or any portion of its interest and rights under this Agreement (including all or any portion of its Notes) to any of the twelve Federal Reserve Banks organized under §4 of the Federal Reserve Act, 12 U.S.C. §341. No such pledge or the enforcement thereof shall release the pledgor Lender from its obligations hereunder or under any of the other Loan Documents.

§20.7. No Assignment by Borrower. The Borrower shall not assign or transfer any of its rights or obligations under any of the Loan Documents without prior Unanimous Lender Approval.

§20.8. Disclosure. The Borrower agrees that, in addition to disclosures made in accordance with standard banking practices, any Lender may disclose information obtained by such Lender pursuant to this Agreement to assignees or participants and potential assignees or participants hereunder.

§20.9. Syndication. The Borrower acknowledges that the Agent intends, and shall have the right, by itself or through its Affiliates, to syndicate or enter into co-lending arrangements with respect to the Term Loan and the Total Commitment. The Agent, in cooperation with the Borrower, will manage all aspects of the syndication, including the selection of co-lenders, the determination of when the Agent will approach potential co-lenders and the final allocations among co-lenders. Each of the Borrower and the Trust agrees to assist the Agent actively in achieving a timely syndication that is reasonably satisfactory to the Agent, such assistance to include, among other things, (a) direct contact during the syndication between the Borrower’s and the Trust’s senior officers, representatives and advisors, on the one hand, and prospective co-lenders, on the other hand at such times and places as the Agent may reasonably request, (b) providing to the Agent all financial and other information with respect to the Borrower and the Trust and the transactions contemplated hereby that the Agent may reasonably request, including but not limited to financial projections relating to the foregoing, and (c) assistance in the preparation of a confidential information memorandum and other marketing materials to be used in connection with the syndication, and the Borrower and the Trust agree to cooperate with the Agent’s and its Affiliate’s syndication and/or co-lending efforts, such cooperation to include, without limitation, the provision of information reasonably requested by potential syndicate members. The Agent shall be entitled with the consent of the Borrower (which shall not be unreasonably withheld or delayed), to change the structure or terms of the Term Loan if the Agent determines that such changes are advisable in order to ensure a successful syndication or an optimal credit structure for the Term Loan, provided the Total Commitment will not be reduced. In addition, the Borrower and the Trust agree that, prior to and during the syndication of the Total Commitment (which for purposes hereof shall be deemed to be completed ninety (90) days after the Closing Date), the Borrower nor the Trust will permit any offering, placement or arrangement of any competing issues of debt securities or commercial bank facilities of the Borrower, the Trust and any of their Subsidiaries, unless approved by the Agent.

Any communication given or transmitted by the Agent or any Lender to Whitestone OP shall be deemed given and transmitted to each and every Borrower.

§23. GOVERNING LAW; CONSENT TO JURISDICTION AND SERVICE.

THE BORROWER AND ITS SUBSIDIARIES HEREBY WAIVE ANY OBJECTION THAT ANY OF THEM MAY NOW OR

HEREAFTER HAVE TO THE VENUE OF ANY SUCH SUIT OR ANY SUCH COURT OR THAT SUCH SUIT IS BROUGHT IN AN INCONVENIENT COURT.

§24. HEADINGS. The captions in this Agreement are for convenience of reference only and shall not define or limit the provisions hereof.

§25. COUNTERPARTS. This Agreement and any amendment hereof may be executed in several counterparts and by each party on a separate counterpart, each of which when so executed and delivered shall be an original, and all of which together shall constitute one instrument. In proving this Agreement it shall not be necessary to produce or account for more than one such counterpart signed by the party against whom enforcement is sought.

§26. ENTIRE AGREEMENT, ETC. The Loan Documents and any other documents executed in connection herewith or therewith express the entire understanding of the parties with respect to the transactions contemplated hereby. Neither this Agreement nor any term hereof may be changed, waived, discharged or terminated, except as provided in §28.

§27. WAIVER OF JURY TRIAL AND CERTAIN DAMAGE CLAIMS. EXCEPT TO THE EXTENT EXPRESSLY PROHIBITED BY LAW, THE BORROWER AND ITS SUBSIDIARIES HEREBY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS AGREEMENT, THE NOTES OR ANY OF THE OTHER LOAN DOCUMENTS, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THEREUNDER OR THE PERFORMANCE OF SUCH RIGHTS AND OBLIGATIONS. EXCEPT TO THE EXTENT EXPRESSLY PROHIBITED BY LAW, THE BORROWER AND ITS SUBSIDIARIES HEREBY WAIVE ANY RIGHT ANY OF THEM MAY HAVE TO CLAIM OR RECOVER IN ANY LITIGATION REFERRED TO IN THE PRECEDING SENTENCE ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES. EACH OF THE BORROWER AND ITS SUBSIDIARIES (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY LENDER OR THE AGENT HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH LENDER OR THE AGENT WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS AND (B) ACKNOWLEDGES THAT THE AGENT AND THE LENDERS HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS TO WHICH THEY ARE PARTIES BY, AMONG OTHER THINGS, THE WAIVERS AND CERTIFICATIONS CONTAINED HEREIN.

§28. CONSENTS, AMENDMENTS, WAIVERS, ETC. Except as otherwise expressly provided in this Agreement, any consent or approval required or permitted by this Agreement may be given, and any term of this Agreement or of any of the other Loan

Documents may be amended, and the performance or observance by the Borrower or the Trust or any of their respective Subsidiaries of any terms of this Agreement or the other Loan Documents or the continuance of any Default or Event of Default may be waived (either generally or in a particular instance and either retroactively or prospectively) with, but only with, the written consent of the Majority Lenders.

Notwithstanding the foregoing, Unanimous Lender Approval shall be required for any amendment, modification or waiver of this Agreement that:

(a) reduces or forgives any principal of the Term Loan or any interest thereon (including any general waiver of interest “breakage” costs) or any fees due any Lender hereunder, or permits any prepayment not otherwise permitted hereunder; or

(b) changes the unpaid principal amount of the Term Loan, reduces the rate of interest applicable to the Term Loan, or reduces any fee payable to the Lenders hereunder; or

(c) changes the date fixed for any payment of principal of or interest on the Term Loan (including, without limitation, any extension of the Maturity Date) or any fees payable hereunder (including, without limitation, the waiver of any monetary Event of Default); or

(d) changes the amount of any Lender’s Commitment (other than pursuant to an assignment permitted under §20.1) or increases the amount of the Total Commitment except as permitted hereunder; or

(e) modifies any provision herein or in any other Loan Document which by the terms thereof expressly requires Unanimous Lender Approval; or

(f) changes the definitions of Majority Lenders or Unanimous Lender Approval; or

(g) releases the Guaranty.

No waiver shall extend to or affect any obligation not expressly waived or impair any right consequent thereon. No course of dealing or delay or omission on the part of the Agent or the Lenders or any Lender in exercising any right shall operate as a waiver thereof or otherwise be prejudicial to such right or any other rights of the Agent or the Lenders. No notice to or demand upon the Borrower shall entitle the Borrower to other or further notice or demand in similar or other circumstances.

Notwithstanding the foregoing, in the event that the Borrower requests any consent, waiver or approval under this Agreement or any other Loan Document, or an amendment or modification hereof or thereof, and one or more Lenders determine not to consent or agree to such consent, waiver, approval, amendment or modification, then the

Lender then acting as Agent hereunder shall have the right to purchase the Commitment of such non-consenting Lender(s) at a purchase price equal to the then outstanding amount of principal, interest and fees then owing to such Lender(s) by the Borrower hereunder, and such non-consenting Lender(s) shall immediately upon request, sell and assign its Commitment and all of its other right, title and interest in the Loans and other Obligations to the Lender then acting as Agent pursuant to an Assignment and Assumption (provided that the selling Lender(s) shall not be responsible to pay any assignment fee in connection therewith).

§29. SEVERABILITY. The provisions of this Agreement are severable, and if any one clause or provision hereof shall be held invalid or unenforceable in whole or in part in any jurisdiction, then such invalidity or unenforceability shall affect only such clause or provision, or part thereof, in such jurisdiction, and shall not in any manner affect such clause or provision in any other jurisdiction, or any other clause or provision of this Agreement in any jurisdiction.

§30. INTEREST RATE LIMITATION. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively, the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this §30 shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Rate to the date of repayment, shall have been received by such Lender.
