Section 1.    THE CREDIT FACILITIES

AMENDED AND RESTATED CREDIT AGREEMENT

This Amended and Restated Credit Agreement is entered into as of November 7, 2014, by and among Whitestone REIT Operating Partnership, L.P., a Delaware limited partnership (the “Borrower” ), Whitestone REIT and each Material Subsidiary from time to time party to this Agreement, as Guarantors, the several financial institutions from time to time party to this Agreement, as Lenders, and BANK OF MONTREAL, as Administrative Agent as provided herein. All capitalized terms used herein without definition shall have the same meanings herein as such terms are defined in Section 5.1 hereof.

PRELIMINARY STATEMENT

WHEREAS, the Borrower, Whitestone REIT and certain Material Subsidiaries of the Borrower, as Guarantors, the financial institutions party thereto as “Lenders” and Bank of Montreal, Chicago Branch, as Administrative Agent and the L/C Issuer, previously entered into a Credit Agreement dated as of February 4, 2013 (as heretofore extended, renewed, amended, modified, amended and restated or supplemented, the “Prior Credit Agreement” ).

WHEREAS, the Borrower has requested that (i) the maturity date under the Prior Credit Agreement be extended, (ii) the maximum amount of the aggregate Revolving Credit Commitments be increased and a swingline be provided under the Revolving Credit, (iii) a new $50,000,000 term loan be extended by the Lenders to the Borrower on the date hereof, and (iv) certain other amendments be made to the Prior Credit Agreement, and the Administrative Agent, the L/C Issuer and the Lenders have agreed to such requests on the terms and conditions set forth in this Agreement, which, for the sake of clarity and convenience, amends and restates the Prior Credit Agreement in its entirety.

NOW, THEREFORE, in consideration of their mutual agreements contained herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby amend and restate the Prior Credit Agreement in its entirety as follows:

Section 1.1.    Revolving Credit Commitments .

(a)    Subject to the terms and conditions hereof, each Lender, by its acceptance hereof, severally agrees to make a loan or loans (individually a “Revolving Loan” and collectively for all the Lenders the “Revolving Loans” ) in U.S. Dollars to the Borrower from time to time on a revolving

basis up to the amount of such Lender’s Revolving Credit Commitment, subject to any reductions thereof pursuant to the terms hereof, before the Revolving Credit Termination Date. The sum of the aggregate principal amount of Revolving Loans, Swingline Loans and L/C Obligations at any time outstanding shall not exceed the lesser of (i) the Revolving Credit Commitments of all Lenders in effect at such time and (ii) the Borrowing Base as then determined and computed. Each Borrowing of Revolving Loans shall be made ratably by the Lenders in proportion to their respective Revolver Percentages. As of the Closing Date immediately prior to the initial Borrowing of Revolving Loans under this Agreement, the aggregate outstanding principal amount of Revolving Loans advanced under the Prior Credit Agreement is $148,100,000, which outstanding Revolving Loans advanced under the Prior Credit Agreement shall continue as outstanding Revolving Loans under this Agreement. As provided in Section 1.6(a) hereof, the Borrower may elect that each Borrowing of Revolving Loans be either Base Rate Loans or Eurodollar Loans. Revolving Loans may be repaid and the principal amount thereof reborrowed before the Revolving Credit Termination Date, subject to the terms and conditions hereof.

(b)     Swingline Loans. (i)  Generally . Subject to the terms and conditions hereof, as part of the Revolving Credit, the Swingline Lender may, in its sole discretion, make loans in U.S. Dollars to the Borrower under the Swingline (individually a “Swingline Loan” and collectively the “Swingline Loans” ) which shall not in the aggregate at any time outstanding exceed the Swingline Sublimit. Swingline Loans may be availed of from time to time and borrowings thereunder may be repaid and used again during the period ending on the Revolving Credit Termination Date. Each Swingline Loan shall be in a minimum amount of $250,000 or such greater amount which is an integral multiple of $100,000. Each Swingline Loan shall bear interest until maturity (whether by acceleration or otherwise) at a rate per annum equal to (x) the rate per annum for Base Rate Loans under the Revolving Credit as from time to time in effect (computed on the basis of a year of 365/366 days for the number of the days elapsed) or (y) the Swingline Lender’s Quoted Rate (computed on the basis of a year of 360 days for the actual number of days elapsed). Interest on the Swingline Loan shall be due and payable by the Borrower on each Interest Payment Date and at maturity (whether by acceleration or otherwise).

(ii)     Requests for Swingline Loans . The Borrower shall give the Administrative Agent prior notice (which may be written or oral) no later than 12:00 Noon (Chicago time) on the date upon which the Borrower requests that the Swingline Loan be made, of the amount and date of the Swingline Loan, and, if applicable, the Interest Period requested therefor. The Administrative Agent shall promptly advise the Swingline Lender of any such notice received from the Borrower. Thereafter, the Swingline Lender shall notify the Administrative Agent (who shall thereafter promptly notify the Borrower) whether or not it has elected to make the Swingline Loan. If the Swingline Lender agrees to make the Swingline Loan, it may in its discretion quote an interest rate to the Borrower at which the Swingline Lender would be willing to make the Swingline Loan

available to the Borrower for the Interest Period so requested (the rate so quoted for a given Interest Period being herein referred to as “Swingline Lender’s Quoted Rate” ). The Borrower acknowledges and agrees that the interest rate quote is given for prompt and irrevocable acceptance. If the Borrower does not so promptly accept the Swingline Lender’s Quoted Rate for the full amount requested by the Borrower for the Swingline Loan, the Swingline Lender’s Quoted Rate shall be deemed immediately withdrawn. If the Swingline Lender’s Quoted Rate is not accepted or otherwise does not apply, the Swingline Loan shall bear interest at the rate per annum for Base Rate Loans under the Revolving Credit as from time to time then currently in effect. Subject to the terms and conditions hereof, the proceeds of the Swingline Loan extended to the Borrower shall be deposited or otherwise wire transferred to the Borrower’s Designated Disbursement Account or as the Borrower, the Administrative Agent, and the Swingline Lender may otherwise agree. Anything contained in the foregoing to the contrary notwithstanding, the undertaking of the Swingline Lender to make Swingline Loans shall be subject to all of the terms and conditions of this Agreement (provided that the Swingline Lender shall be entitled to assume that the conditions precedent to an advance of the Swingline Loan have been satisfied unless notified to the contrary by the Administrative Agent or the Required Lenders).

(iii)     Refunding Swingline Loans . In its sole and absolute discretion, the Swingline Lender may at any time, on behalf of the Borrower (which hereby irrevocably authorizes the Swingline Lender to act on its behalf for such purpose) and with notice to the Borrower and the Administrative Agent, request each Lender to make a Revolving Loan in the form of a Base Rate Loan in an amount equal to such Lender’s Revolver Percentage of the amount of the Swingline Loans outstanding on the date such notice is given (which Loans shall thereafter bear interest as provided for in Section 1.4(a)). Unless an Event of Default described in Section 9.1(j) or 9.1(k) exists with respect to the Borrower, regardless of the existence of any other Event of Default, each Lender shall make the proceeds of its requested Revolving Loan available to the Administrative Agent for the account of the Swingline Lender), in immediately available funds, at the Administrative Agent’s office in Chicago, Illinois (or such other location designated by the Administrative Agent), before 12:00 Noon (Chicago time) on the Business Day following the day such notice is given. The Administrative Agent shall promptly remit the proceeds of such Borrowing to the Swingline Lender to repay the outstanding Swingline Loans.

(iv)     Participation in Swingline Loans. If any Lender refuses or otherwise fails to make a Revolving Loan when requested by the Swingline Lender pursuant to Section 1.1(b)(iii) above (because an Event of Default described in Section 9.1(j) or 9.1(k) exists with respect to the Borrower or otherwise), such Lender will, by the time and in the manner such Revolving Loan was to have been funded to the Swingline Lender, purchase from the Swingline Lender an undivided participating interest in the outstanding Swingline Loans in an amount equal to its Revolver Percentage of the aggregate principal amount of Swingline Loans that were to have been repaid with such Revolving

Loans. From and after the date of any such purchase, the parties hereto hereby acknowledge and agree that the Swingline Loans shall thereafter bear interest as Base Rate Loans as provided for in Section 1.1(b)(i)(x) above). Each Lender that so purchases a participation in a Swingline Loan shall thereafter be entitled to receive its Revolver Percentage of each payment of principal received on the Swingline Loan and of interest received thereon accruing from the date such Lender funded to the Swingline Lender its participation in such Loan. The several obligations of the Lenders under this Section shall be absolute, irrevocable, and unconditional under any and all circumstances whatsoever and shall not be subject to any set‑off, counterclaim or defense to payment which any Lender may have or have had against the Borrower, any other Lender, or any other Person whatsoever. Without limiting the generality of the foregoing, such obligations shall not be affected by any Default or by any reduction or termination of the Commitments of any Lender, and each payment made by a Lender under this Section shall be made without any offset, abatement, withholding, or reduction whatsoever.

Section 1.2.    Term Loan Commitments. (a) The Loan Parties, Administrative Agent and Lenders hereby acknowledge and agree that the Lenders with “Term Loan Commitments” under the Prior Credit Agreement severally and not jointly advanced a loan (the “Term A Loan” ) under the Prior Credit Agreement in the amount of $50,000,000 and, in connection therewith, the “Term Loan Commitments” under the Prior Credit Agreement simultaneously terminated and no Lender under this Agreement has any obligation to advance a Term A Loan to the Borrower. As of the Closing Date, the aggregate outstanding principal amount of Term A Loans is $50,000,000, which Term A Loans continue as outstanding obligations under this Agreement ratably held by each Lender in proportion to their respective Term A Loan Commitments. As provided in Section 1.6(a) hereof, the Borrower may elect that the Term A Loan be outstanding as a Base Rate Loan or Eurodollar Loan. No amount repaid or prepaid on any Term A Loan may be borrowed again.

(b)    Subject to the terms and conditions hereof, each Lender, by its acceptance hereof, severally agrees to make a loan (individually a “Term B Loan” and collectively for all the Lenders the “Term B Loans” ) in U.S. Dollars to the Borrower in the amount of such Lender’s Term B Loan Commitment. The Term B Loans shall be advanced in a single Borrowing on the Closing Date and shall be made ratably by the Lenders in proportion to their respective Term B Loan Percentages, at which time the Term B Loan Commitments shall expire. As provided in Section 1.6(a) hereof, the Borrower may elect that the Term B Loans be outstanding as Base Rate Loans or Eurodollar Loans. No amount repaid or prepaid on any Term B Loan may be borrowed again.

Section 1.3.    Letters of Credit . (a)  General Terms. Subject to the terms and conditions hereof, as part of the Revolving Credit, the L/C Issuer shall issue standby and commercial letters of credit (each a “Letter of Credit” ) or amend or extend Letters for Credit issued by it for the account of the Borrower or for the account of the Borrower and one or more of its Subsidiaries in an aggregate

undrawn face amount up to the L/C Sublimit; provided that if a Letter of Credit is issued on account of a Subsidiary, the Borrower shall be the primary obligor for all obligations with respect to such Letter of Credit. Each Letter of Credit shall be issued by the L/C Issuer, but each Lender shall be obligated to reimburse the L/C Issuer for such Lender’s Revolver Percentage of the amount of each drawing thereunder and, accordingly, each Letter of Credit shall constitute usage of the Revolving Credit Commitment of each Lender pro rata in an amount equal to its Revolver Percentage of the L/C Obligations then outstanding.

(b)     Applications. At any time prior to thirty (30) days before the Revolving Credit Termination Date, the L/C Issuer shall, at the request of the Borrower, issue one or more Letters of Credit in U.S. Dollars, in a form satisfactory to the L/C Issuer, with expiration dates no later than the earlier of 12 months from the date of issuance (or which are cancelable not later than 12 months from the date of issuance and each renewal) or thirty (30) days prior to the Revolving Credit Termination Date, in an aggregate face amount as set forth above, upon the receipt of an application duly executed by the Borrower and, if such Letter of Credit is for the account of one of its Subsidiaries, such Subsidiary for the relevant Letter of Credit in the form then customarily prescribed by the L/C Issuer for the Letter of Credit requested (each an “Application” ). Without limiting the foregoing limitation regarding Letter of Credit expiration dates, the Borrower agrees that if on the Revolving Credit Termination Date any Letters of Credit remain outstanding the Borrower shall then deliver to the Administrative Agent, without notice or demand, Cash Collateral in an amount equal to 102% of the aggregate amount of each Letter of Credit then outstanding (which shall be held by the Administrative Agent pursuant to the terms of Section 9.4). Notwithstanding anything contained in any Application to the contrary: (i) the Borrower shall pay fees in connection with each Letter of Credit as set forth in Section 2.1 hereof, (ii) except as otherwise provided in Section 1.8 or Section 1.14 hereof, unless an Event of Default exists, the L/C Issuer will not call for the funding by the Borrower of any amount under a Letter of Credit before being presented with a drawing thereunder, and (iii) if the L/C Issuer is not timely reimbursed for the amount of any drawing under a Letter of Credit on the date such drawing is paid, the Borrower’s obligation to reimburse the L/C Issuer for the amount of such drawing shall bear interest (which the Borrower hereby promises to pay) from and after the date such drawing is paid at a rate per annum equal to the sum of the Applicable Margin plus the Base Rate from time to time in effect (computed on the basis of a year of 365 or 366 days, as the case may be, and the actual number of days elapsed). If the L/C Issuer issues any Letter of Credit with an expiration date that is automatically extended unless the L/C Issuer gives notice that the expiration date will not so extend beyond its then scheduled expiration date, the L/C Issuer will, unless the Administrative Agent and the Required Lenders instruct the L/C Issuer otherwise, give such notice of non‑renewal before the time necessary to prevent such automatic extension if before such required notice date: (i) the expiration date of such Letter of Credit if so extended would be after the date that is thirty (30) days prior to the Revolving Credit Termination Date, (ii) the Revolving Credit Commitments have been terminated, or (iii) a Default

or an Event of Default exists and either the Administrative Agent or the Required Lenders (with notice to the Administrative Agent) have given the L/C Issuer instructions not to so permit the extension of the expiration date of such Letter of Credit. The L/C Issuer agrees to issue amendments to the Letter(s) of Credit increasing the amount, or extending the expiration date, thereof at the request of the Borrower subject to the conditions of Section 7 hereof and the other terms of this Section 1.3. Notwithstanding anything contained herein to the contrary, the L/C Issuer shall be under no obligation to issue, extend or amend any Letter of Credit if a default of any Lender’s obligations to fund under Section 1.3(c) exists or any Lender is at such time a Defaulting Lender hereunder, unless the L/C Issuer has entered into arrangements with Borrower or such Lender satisfactory to the L/C Issuer to eliminate the L/C Issuer’s risk with respect to such Lender.

(c)     The Reimbursement Obligations. Upon receipt from the beneficiary of any Letter of Credit of any notice of a drawing under such Letter of Credit, the L/C Issuer shall promptly notify the Borrower and the Administrative Agent thereof. Subject to Section 1.3(b) hereof, the obligation of the Borrower to reimburse the L/C Issuer for all drawings under a Letter of Credit (a “Reimbursement Obligation” ) shall be governed by the Application related to such Letter of Credit, except that reimbursement shall be made by no later than 12:00 Noon (Chicago time) on the date when each drawing is to be paid if the Borrower has been informed of such drawing by the L/C Issuer on or before 11:00 a.m. (Chicago time) on the date when such drawing is to be paid or, if notice of such drawing is given to the Borrower after 11:00 a.m. (Chicago time) on the date when such drawing is to be paid, by no later than 12:00 Noon (Chicago time) on the following Business Day, in immediately available funds at the Administrative Agent’s principal office in Chicago, Illinois or such other office as the Administrative Agent may designate in writing to the Borrower (who shall thereafter cause to be distributed to the L/C Issuer such amount(s) in like funds). If the Borrower does not make any such reimbursement payment on the date due and the Participating Lenders fund their participations therein in the manner set forth in Section 1.3(e) below, then all payments thereafter received by the Administrative Agent in discharge of any of the relevant Reimbursement Obligations shall be distributed in accordance with Section 1.3(e) below.

(d)     Obligations Absolute. The Borrower's obligation to reimburse L/C Obligations as provided in subsection (c) of this Section shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement and the relevant Application under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the L/C Issuer under a Letter of Credit against presentation of a draft or other document that does not strictly comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this

Section, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. None of the Administrative Agent, the Lenders, or the L/C Issuer shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the L/C Issuer; provided that the foregoing shall not be construed to excuse the L/C Issuer from liability to the Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by the L/C Issuer’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the L/C Issuer (as determined by a court of competent jurisdiction by final and non-appealable judgment), the L/C Issuer shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the L/C Issuer may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(e)     The Participating Interests. Each Lender (other than the Lender acting as the L/C Issuer in issuing the relevant Letter of Credit), by its acceptance hereof, severally agrees to purchase from the L/C Issuer, and the L/C Issuer hereby agrees to sell to each such Lender (a “Participating Lender” ), an undivided percentage participating interest (a “Participating Interest”) , to the extent of its Revolver Percentage, in each Letter of Credit issued by, and each Reimbursement Obligation owed to, the L/C Issuer. Upon any failure by the Borrower to pay any Reimbursement Obligation at the time required on the date the related drawing is to be paid, as set forth in Section 1.3(c) above, or if the L/C Issuer is required at any time to return to the Borrower or to a trustee, receiver, liquidator, custodian or other Person any portion of any payment of any Reimbursement Obligation, each Participating Lender shall, not later than the Business Day it receives a certificate in the form of Exhibit A hereto from the L/C Issuer (with a copy to the Administrative Agent) to such effect, if such certificate is received before 1:00 p.m. (Chicago time), or if received later than 1:00 p.m. (Chicago time), on the following Business Day, pay to the Administrative Agent for the account of the L/C Issuer an amount equal to such Participating Lender’s Revolver Percentage of such unpaid or recaptured Reimbursement Obligation together with interest on such amount accrued from the

date the related payment was made by the L/C Issuer to the date of such payment by such Participating Lender at a rate per annum equal to: (i) from the date the related payment was made by the L/C Issuer to the date two (2) Business Days after payment by such Participating Lender is due hereunder, the Federal Funds Rate for each such day and (ii) from the date two (2) Business Days after the date such payment is due from such Participating Lender to the date such payment is made by such Participating Lender, the Base Rate in effect for each such day. Each such Participating Lender shall thereafter be entitled to receive its Revolver Percentage of each payment received in respect of the relevant Reimbursement Obligation and of interest paid thereon, with the L/C Issuer retaining its Revolver Percentage thereof as a Lender hereunder. The several obligations of the Participating Lenders to the L/C Issuer under this Section 1.3 shall be absolute, irrevocable, and unconditional under any and all circumstances whatsoever and shall not be subject to any set‑off, counterclaim or defense to payment which any Participating Lender may have or have had against the Borrower, the L/C Issuer, the Administrative Agent, any Lender or any other Person whatsoever. Without limiting the generality of the foregoing, such obligations shall not be affected by any Default or Event of Default or by any reduction or termination of any Commitment of any Lender, and each payment by a Participating Lender under this Section 1.3 shall be made without any offset, abatement, withholding or reduction whatsoever.

(f)     Indemnification. The Participating Lenders shall, to the extent of their respective Revolver Percentages, indemnify the L/C Issuer (to the extent not reimbursed by the Borrower, without limiting its obligation to do so) against any cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from the L/C Issuer’s gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and non-appealable judgment) that the L/C Issuer may suffer or incur in connection with any Letter of Credit issued by it. The obligations of the Participating Lenders under this Section 1.3(f) and all other parts of this Section 1.3 shall survive termination of this Agreement and of all Applications, Letters of Credit, and all drafts and other documents presented in connection with drawings thereunder.

(g)     Manner of Requesting a Letter of Credit. The Borrower shall provide at least five (5) Business Days’ advance written notice to the Administrative Agent of each request for the issuance of a Letter of Credit, such notice in each case to be accompanied by an Application for such Letter of Credit properly completed and executed by the Borrower and, in the case of an extension or amendment or an increase in the amount of a Letter of Credit, a written request therefor, in a form acceptable to the Administrative Agent and the L/C Issuer, in each case, together with the fees called for by this Agreement. The Administrative Agent shall promptly notify the L/C Issuer of the Administrative Agent’s receipt of each such notice (and the L/C Issuer shall be entitled to assume that the conditions precedent to any such issuance, extension, amendment or increase have been satisfied unless notified to the contrary by the Administrative Agent or the Required Lenders)

and the L/C Issuer shall promptly notify the Administrative Agent and the Lenders of the issuance of the Letter of Credit so requested.

(h)     Replacement of the L/C Issuer . The L/C Issuer may be replaced at any time by any other Lender or an Affiliate of any Lender by written agreement among the Borrower, the Administrative Agent, the replaced L/C Issuer and the successor L/C Issuer. The Administrative Agent shall notify the Lenders of any such replacement of the L/C Issuer. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced L/C Issuer. From and after the effective date of any such replacement (i) the successor L/C Issuer shall have all the rights and obligations of the L/C Issuer under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term “L/C Issuer” shall be deemed to refer to such successor or to any previous L/C Issuer, or to such successor and all previous L/C Issuers, as the context shall require. After the replacement of the L/C Issuer hereunder, the replaced L/C Issuer shall remain a party hereto and shall continue to have all the rights and obligations of the L/C Issuer under this Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit.

Section 1.4.    Applicable Interest Rates; Investment Grade Credit Rating Interest Rate Election . (a)  Base Rate Loans. Each Base Rate Loan made or maintained by a Lender shall bear interest (computed on the basis of a year of 365 or 366 days, as the case may be, and the actual days elapsed) on the unpaid principal amount thereof from the date such Loan is advanced, or created by conversion from a Eurodollar Loan, until maturity (whether by acceleration or otherwise) at a rate per annum equal to the sum of the Applicable Margin plus the Base Rate from time to time in effect, payable by the Borrower on each Interest Payment Date and at maturity (whether by acceleration or otherwise).

“Base Rate” means, for any day, the rate per annum equal to the greatest of: (a) the rate of interest announced or otherwise established by the Administrative Agent from time to time as its prime commercial rate, or its equivalent, for U.S. Dollar loans to borrowers located in the United States as in effect on such day, with any change in the Base Rate resulting from a change in said prime commercial rate to be effective as of the date of the relevant change in said prime commercial rate (it being acknowledged and agreed that such rate may not be the Administrative Agent’s best or lowest rate), (b) the sum of (i) the rate determined by the Administrative Agent to be the average (rounded upward, if necessary, to the next higher 1/100 of 1%) of the rates per annum quoted to the Administrative Agent at approximately 10:00 a.m. (Chicago time) (or as soon thereafter as is practicable) on such day (or, if such day is not a Business Day, on the immediately preceding Business Day) by two or more Federal funds brokers selected by the Administrative Agent for sale to the Administrative Agent at face value of Federal funds in the secondary market in an amount equal or comparable to the principal amount for which such rate is being determined, plus (ii) 1/2

of 1%, and (c) the LIBOR Quoted Rate for such day plus 1.00%. As used herein, the term “LIBOR Quoted Rate” means, for any day, the rate per annum equal to the quotient of (i) the rate per annum (rounded upwards, if necessary, to the next higher one hundred‑thousandth of a percentage point) for deposits in U.S. Dollars for a one-month interest period which appears on the LIBOR01 Page as of 11:00 a.m. (London, England time) on such day (or, if such day is not a Business Day, on the immediately preceding Business Day) divided by (ii) one (1) minus the Eurodollar Reserve Percentage.

(b)     Eurodollar Loans. Each Eurodollar Loan made or maintained by a Lender shall bear interest during each Interest Period it is outstanding (computed on the basis of a year of 360 days and actual days elapsed) on the unpaid principal amount thereof from the date such Loan is advanced or continued, or created by conversion from a Base Rate Loan, until maturity (whether by acceleration or otherwise) at a rate per annum equal to the sum of the Applicable Margin plus the Adjusted LIBOR applicable for such Interest Period, payable by the Borrower on each Interest Payment Date and at maturity (whether by acceleration or otherwise).

“Adjusted LIBOR” means, for any Borrowing of Eurodollar Loans, a rate per annum determined in accordance with the following formula:

Adjusted LIBOR    =                           LIBOR                     

1 ‑ Eurodollar Reserve Percentage

“Eurodollar Reserve Percentage” means the maximum reserve percentage, expressed as a decimal, at which reserves (including, without limitation, any emergency, marginal, special, and supplemental reserves) are imposed by the Board of Governors of the Federal Reserve System (or any successor) on “eurocurrency liabilities” , as defined in such Board’s Regulation D (or any successor thereto), subject to any amendments of such reserve requirement by such Board or its successor, taking into account any transitional adjustments thereto. For purposes of this definition, the relevant Loans shall be deemed to be “eurocurrency liabilities” as defined in Regulation D without benefit or credit for any prorations, exemptions or offsets under Regulation D. The Eurodollar Reserve Percentage shall be adjusted automatically on and as of the effective date of any change in any such reserve percentage.

“LIBOR” means, for an Interest Period for a Borrowing of Eurodollar Loans, the greater of (i) zero and (ii) (a) the LIBOR Index Rate for such Interest Period, if such rate is available, or (b) if the LIBOR Index Rate cannot be determined, the arithmetic average of the rates of interest per annum (rounded upwards, if necessary, to the nearest 1/100 of 1%) at which deposits in U.S. Dollars in immediately available funds are offered to the Administrative Agent at 11:00 a.m. (London, England time) two (2) Business Days before the beginning of such Interest Period by

three (3) or more major banks in the interbank eurodollar market selected by the Administrative Agent for delivery on the first day of and for a period equal to such Interest Period and in an amount equal or comparable to the principal amount of the Eurodollar Loan scheduled to be made as part of such Borrowing.

“LIBOR Index Rate” means, for any Interest Period, the rate per annum (rounded upwards, if necessary, to the next higher one hundred‑thousandth of a percentage point) for deposits in U.S. Dollars for a period equal to such Interest Period, which appears on the LIBOR01 Page as of 11:00 a.m. (London, England time) on the day two (2) Business Days before the commencement of such Interest Period.

“LIBOR01 Page” means the display designated as “LIBOR01 Page” on the Reuters Service (or such other page as may replace the LIBOR01 Page on that service or such other service as may be nominated by the ICE Benchmark Administration (“ ICE” ) (or the successor thereto if ICE is no longer making the London Interbank Offered Rate available) as the information vendor for the purpose of displaying the London Interbank Offered Rate for U.S. Dollar deposits).

(c)     Rate Determinations. The Administrative Agent shall determine each interest rate applicable to the Loans and the Reimbursement Obligations hereunder, and its determination thereof shall be conclusive and binding except in the case of manifest error.

(d)     Investment Grade Credit Rating Interest Rate Election. At any time after the Borrower receives an Investment Grade Credit Rating from two Rating Agencies, the Borrower may, so long as no Default then exists and is continuing, irrevocably elect (an “Interest Rate Election” ) by written notice to the Administrative Agent, accompanied by reasonable evidence of the Borrower’s Credit Ratings from two Rating Agencies, that the interest rate and fee margins set forth in clause (b) of the definition of “Applicable Margin” herein shall at all times thereafter be applicable to all credit extensions under this Agreement. The Administrative Agent shall provide the Lenders and the L/C Issuer with prompt notice of its receipt of any Interest Rate Election. On the day after the date of the Administrative Agent’s receipt of any Interest Rate Election (the date of the Administrative Agent’s receipt of such election is the “Interest Rate Election Date” ), the margins set forth in clause (a) of the definition of “Applicable Margin” herein shall no longer apply and the commitment fee under Section 2.1(a) shall no longer continue to accrue.

Section 1.5.    Minimum Borrowing Amounts; Maximum Eurodollar Loans . Each Borrowing of Base Rate Loans advanced under a Credit shall be in an amount not less than $100,000. Each Borrowing of Eurodollar Loans advanced, continued or converted under a Credit shall be in an amount equal to $500,000 or such greater amount which is an integral multiple of $100,000. Without

the Administrative Agent’s consent, there shall not be more than ten (10) Borrowings of Eurodollar Loans outstanding hereunder.

Section 1.6.    Manner of Borrowing Loans and Designating Applicable Interest Rates . (a)  Notice to the Administrative Agent. The Borrower shall give notice to the Administrative Agent by no later than 10:00 a.m. (Chicago time): (i) at least three (3) Business Days before the date on which the Borrower requests the Lenders to advance a Borrowing of Eurodollar Loans and (ii) on the date the Borrower requests the Lenders to advance a Borrowing of Base Rate Loans. The Loans included in each Borrowing shall bear interest initially at the type of rate specified in such notice of a new Borrowing. Thereafter, subject to the terms and conditions hereof, the Borrower may from time to time elect to change or continue the type of interest rate borne by each Borrowing or, subject to the minimum amount requirement for each outstanding Borrowing set forth in Section 1.5 hereof, a portion thereof, as follows: (i) if such Borrowing is of Eurodollar Loans, on the last day of the Interest Period applicable thereto, the Borrower may continue part or all of such Borrowing as Eurodollar Loans or convert part or all of such Borrowing into Base Rate Loans or (ii) if such Borrowing is of Base Rate Loans, on any Business Day, the Borrower may convert all or part of such Borrowing into Eurodollar Loans for an Interest Period or Interest Periods specified by the Borrower. The Borrower shall give all such notices requesting the advance, continuation or conversion of a Borrowing to the Administrative Agent by telephone, telecopy, or other telecommunication device acceptable to the Administrative Agent (which notice shall be irrevocable once given and, if by telephone, shall be promptly confirmed in writing), substantially in the form attached hereto as Exhibit B (Notice of Borrowing) or Exhibit C (Notice of Continuation/Conversion), as applicable, or in such other form acceptable to the Administrative Agent. Notice of the continuation of a Borrowing of Eurodollar Loans for an additional Interest Period or of the conversion of part or all of a Borrowing of Base Rate Loans into Eurodollar Loans must be given by no later than 10:00 a.m. (Chicago time) at least three (3) Business Days before the date of the requested continuation or conversion. All such notices concerning the advance, continuation or conversion of a Borrowing shall specify the date of the requested advance, continuation or conversion of a Borrowing (which shall be a Business Day), the amount of the requested Borrowing to be advanced, continued or converted, the type of Loans to comprise such new, continued or converted Borrowing and, if such Borrowing is to be comprised of Eurodollar Loans, the Interest Period applicable thereto. No Borrowing of Eurodollar Loans shall be advanced, continued, or created by conversion if any Default or Event of Default then exists. The Borrower agrees that the Administrative Agent may rely on any such telephonic, telecopy or other telecommunication notice given by any person the Administrative Agent in good faith believes is an Authorized Representative without the necessity of independent investigation, and in the event any such notice by telephone conflicts with any written confirmation such telephonic notice shall govern if the Administrative Agent has acted in reliance thereon.

(b)     Notice to the Lenders . The Administrative Agent shall give prompt telephonic, telecopy or other telecommunication notice to each Lender of any notice from the Borrower received pursuant to Section 1.6(a) above and, if such notice requests the Lenders to make Eurodollar Loans, the Administrative Agent shall give notice to the Borrower and each Lender by like means of the interest rate applicable thereto promptly after the Administrative Agent has made such determination.

(c)     Borrower’s Failure to Notify . If the Borrower fails to give notice pursuant to Section 1.6(a) above of the continuation or conversion of any outstanding principal amount of a Borrowing of Eurodollar Loans before the last day of its then current Interest Period within the period required by Section 1.6(a) and such Borrowing is not prepaid in accordance with Section 1.8(a), such Borrowing shall automatically be converted into a Borrowing of Base Rate Loans. In the event the Borrower fails to give notice pursuant to Section 1.6(a) above of a Borrowing equal to the amount of a Reimbursement Obligation and has not notified the Administrative Agent by 12:00 noon (Chicago time) on the day such Reimbursement Obligation becomes due that it intends to repay such Reimbursement Obligation through funds not borrowed under this Agreement, the Borrower shall be deemed to have requested a Borrowing of Base Rate Loans under the Revolving Credit (or, at the option of the Swingline Lender, under the Swingline) on such day in the amount of the Reimbursement Obligation then due, which Borrowing shall be applied to pay the Reimbursement Obligation then due.

(d)     Disbursement of Loans . Not later than 1:00 p.m. (Chicago time) on the date of any requested advance of a new Borrowing, subject to Section 7 hereof, each Lender shall make available its Loan comprising part of such Borrowing in funds immediately available at the principal office of the Administrative Agent in Chicago, Illinois (or at such other location as the Administrative Agent shall designate). The Administrative Agent shall make the proceeds of each new Borrowing available to the Borrower on the date of such Borrowing as instructed by the Borrower.

(e)     Administrative Agent Reliance on Lender Funding. Unless the Administrative Agent shall have been notified by a Lender prior to (or, in the case of a Borrowing of Base Rate Loans, by 1:00 p.m. (Chicago time) on) the date on which such Lender is scheduled to make payment to the Administrative Agent of the proceeds of a Loan (which notice shall be effective upon receipt) that such Lender does not intend to make such payment, the Administrative Agent may assume that such Lender has made such payment when due and the Administrative Agent may in reliance upon such assumption (but shall not be required to) make available to the Borrower the proceeds of the Loan to be made by such Lender and, if any Lender has not in fact made such payment to the Administrative Agent, such Lender shall, on demand, pay to the Administrative Agent the amount made available to the Borrower attributable to such Lender together with interest thereon in respect of each day during the period commencing on the date such amount was made available to the Borrower and ending on (but excluding) the date such Lender pays such amount to the Administrative

Agent at a rate per annum equal to: (i) from the date the related advance was made by the Administrative Agent to the date two (2) Business Days after payment by such Lender is due hereunder, the Federal Funds Rate for each such day and (ii) from the date two (2) Business Days after the date such payment is due from such Lender to the date such payment is made by such Lender, the Base Rate in effect for each such day. If such amount is not received from such Lender by the Administrative Agent immediately upon demand, the Borrower will, on demand, repay to the Administrative Agent the proceeds of the Loan attributable to such Lender with interest thereon at a rate per annum equal to the interest rate applicable to the relevant Loan, but without such payment being considered a payment or prepayment of a Loan under Section 1.11 hereof so that the Borrower will have no liability under such Section with respect to such payment.

Section 1.7.    Maturity of Loans. (a) Term A Loan . The Term A Loan, both for principal and interest not sooner paid, shall mature and be due and payable by the Borrower on the Term A Credit Termination Date.

(b)     Term B Loan. The Term B Loan, both for principal and interest not sooner paid, shall mature and be due and payable by the Borrower on the Term B Credit Termination Date.

(c)     Revolving Loans. Each Revolving Loan, both for principal and interest not sooner paid, shall mature and be due and payable by the Borrower on the Revolving Credit Termination Date.

(d)     Swingline Loans . Each Swingline Loan, both for principal and interest not sooner paid, shall mature and be due and payable by the Borrower on the Revolving Credit Termination Date.

Section 1.8.    Prepayments. (a)  Optional . The Borrower may prepay at any time or from time to time in whole or in part (but, if in part, then: (i) if such Borrowing is of Base Rate Loans, in an amount not less than $100,000, (ii) if such Borrowing is of Eurodollar Loans, in an amount not less than $500,000, and (iii) in each case, in an amount such that the minimum amount required for a Borrowing pursuant to Section 1.5 hereof remains outstanding) without premium or penalty (subject to Section 1.11 hereof) any Borrowing of Eurodollar Loans at any time upon three (3) Business Days prior notice by the Borrower to the Administrative Agent or, in the case of a Borrowing of Base Rate Loans, notice delivered by the Borrower to the Administrative Agent no later than 10:00 a.m. (Chicago time) on the date of prepayment (or, in any case, such shorter period of time then agreed to by the Administrative Agent), such prepayment to be made by the payment of the principal amount to be prepaid and, in the case of any Eurodollar Loans or Swingline Loans, accrued interest thereon to the date fixed for prepayment plus any amounts due the Lenders under Section 1.11 hereof.

(b)     Mandatory .

    (i)    If the outstanding Swingline Loans, Revolving Loans and L/C Obligations at any time exceed the Revolving Credit Commitments then in effect, the Borrower shall prepay the Swingline Loans, Revolving Loans, and, if necessary, Cash Collateralize the L/C Obligations by the amount necessary to reduce the sum of the aggregate principal amount of Swingline Loans, Revolving Loans, and L/C Obligations then outstanding to an amount which does not exceed the Revolving Credit Commitments then in effect.

(ii)    If at any time the sum of the unpaid principal balance of the Term Loans, the Incremental Term Loans (if any), the Revolving Loans, Swingline Loans and the L/C Obligations then outstanding shall be in excess of the Borrowing Base as then determined and computed, the Borrower shall immediately and without notice or demand pay over the amount of the excess to the Administrative Agent for the account of the Lenders as and for a mandatory prepayment on such Obligations, with each such prepayment first to be applied to the Swingline Loans and Revolving Loans until paid in full, then to the Term A Loan, Term B Loan and the Incremental Term Loans (if any) on a combined ratable basis with respect to all such Loans until such Loans are paid in full, with any remaining balance to be held by the Administrative Agent in the Collateral Account as security for the Obligations owing with respect to the Letters of Credit.

(iii)    Unless the Borrower otherwise directs, prepayments of Loans under this Section 1.8(b) shall be applied first to Borrowings of Base Rate Loans until payment in full thereof with any balance applied to Borrowings of Eurodollar Loans in the order in which their Interest Periods expire. Each prepayment of Loans under this Section 1.8(b) shall be made by the payment of the principal amount to be prepaid and, in the case of any Eurodollar Loans or Swingline Loans, accrued interest thereon to the date of prepayment together with any amounts due the Lenders under Section 1.11 hereof. Each prefunding of L/C Obligations shall be made in accordance with Section 9.4 hereof.

(c)    Any amount of Swingline Loans or Revolving Loans paid or prepaid before the Revolving Credit Termination Date may, subject to the terms and conditions of this Agreement, be borrowed, repaid and borrowed again. No amount of Term Loans or Incremental Term Loans paid or prepaid may be reborrowed.

Section 1.9.    Default Rate . Notwithstanding anything to the contrary contained herein, while any Event of Default exists or after acceleration, the 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 Loans and Reimbursement Obligations, and letter of credit fees at a rate per annum equal to:

(a)    for any Base Rate Loan or the Swingline Loan bearing interest based on the Base Rate, the sum of 2.0% plus the Applicable Margin plus the Base Rate from time to time in effect;

(b)    for any Eurodollar Loan or the Swingline Loan bearing interest at the Administrative Agent’s Quoted Rate, the sum of 2.0% plus the rate of interest in effect thereon at the time of such default until the end of the Interest Period applicable thereto and, thereafter, at a rate per annum equal to the sum of 2.0% plus the Applicable Margin for Base Rate Loans plus the Base Rate from time to time in effect;

(c)    for any Reimbursement Obligation, the sum of 2.0% plus the amounts due under Section 1.3 with respect to such Reimbursement Obligation;

(d)    for any Letter of Credit, the sum of 2.0% plus the letter of credit fee due under Section 2.1 with respect to such Letter of Credit; and

(e)    for any other amount owing hereunder not covered by clauses (a) through (d) above, the sum of 2.0% plus the Applicable Margin plus the Base Rate from time to time in effect;

provided, however, that in the absence of acceleration, any adjustments pursuant to this Section shall be made at the election of the Administrative Agent, acting at the request or with the consent of the Required Lenders, with written notice to the Borrower. While any Event of Default exists or after acceleration, interest shall be paid on demand of the Administrative Agent at the request or with the consent of the Required Lenders.

Section 1.10.    Evidence of Indebtedness . (a) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(b)    The Administrative Agent shall also maintain accounts in which it will record (i) the amount of each Loan made hereunder, the type thereof and the Interest Period with respect thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder from the Borrower and each Lender’s share thereof.

(c)    The entries maintained in the accounts maintained pursuant to paragraphs (a) and (b) above shall be prima facie evidence of the existence and amounts of the Obligations therein recorded absent manifest error; provided, however, that the failure of the Administrative Agent or any Lender

to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Obligations in accordance with their terms.

(d)    Any Lender may request that its Loans be evidenced by a promissory note or notes substantially in the forms (which forms may be altered to include amendment and restatement language to evidence the amendment and restatement of a Note issued to a Lender under the Prior Credit Agreement, if applicable) of Exhibit D-1 (in the case of its Term A Loan and referred to herein as a “Term A Note” ), D-2 (in the case of its Term B Loan and referred to herein as a “Term B Note” ), D-3 (in the case of its Revolving Loans and referred to herein as a “Revolving Note” ), D‑4 (in the case of its Incremental Term Loans and referred to herein as the “Incremental Term Note” ), or D‑5 (in the case of its Swingline Loans and referred to herein as a “Swing Note” ) as applicable (the Term A Notes, Term B Notes, the Revolving Notes, the Incremental Term Notes and Swing Note being hereinafter referred to collectively as the “Notes” and individually as a “Note” ). In such event, the Borrower shall prepare, execute and deliver to such Lender a Note payable to such Lender or its registered assigns in the amount of the relevant Term Loan, Revolving Credit Commitment, Swingline Sublimit or Incremental Term Loan, as applicable. Thereafter, the Loans evidenced by such Note or Notes and interest thereon shall at all times (including after any assignment pursuant to Section 12.10) be represented by one or more Notes payable to the order of the payee named therein or any assignee pursuant to Section 12.10, except to the extent that any such Lender or assignee subsequently returns any such Note for cancellation and requests that such Loans once again be evidenced as described above.

Section 1.11.    Funding Indemnity . If any Lender shall incur any loss, cost or expense (including, without limitation, any loss, cost or expense incurred by reason of the liquidation or re‑employment of deposits or other funds acquired by such Lender to fund or maintain any Eurodollar Loan or Swingline Loan bearing interest at the Swingline Lender’s Quoted Rate or the relending or reinvesting of such deposits or amounts paid or prepaid to such Lender) as a result of:

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

(b)    any failure (because of a failure to meet the conditions of Section 7 or otherwise) by the Borrower to borrow or continue a Eurodollar Loan or the Swingline Loan, or to convert a Base Rate Loan into a Eurodollar Loan or the Swingline Loan, on the date specified in a notice given pursuant to Section 1.6(a) hereof,

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

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

then, upon the demand of such Lender, the Borrower shall pay to such Lender such amount as will reimburse such Lender for such loss, cost or expense. If any Lender makes such a claim for compensation, it shall provide to the Borrower, with a copy to the Administrative Agent, a certificate setting forth the amount of such loss, cost or expense in reasonable detail and the amounts shown on such certificate shall be conclusive if reasonably determined.

Section 1.12.    Commitment Terminations . (a)  Optional Revolving Credit Terminations. The Borrower shall have the right at any time and from time to time, upon five (5) Business Days prior written notice to the Administrative Agent (or such shorter period of time agreed to by the Administrative Agent), to terminate the Revolving Credit Commitments without premium or penalty and in whole or in part, any partial termination to be (i) in an amount not less than $5,000,000 and (ii) allocated ratably among the Lenders in proportion to their respective Revolver Percentages, provided that (x) the Revolving Credit Commitments may not be reduced to an amount less than the sum of the aggregate principal amount of Swingline Loans, Revolving Loans and L/C Obligations then outstanding and (y) any partial termination of the Revolving Credit Commitments shall not reduce the aggregate Revolving Credit Commitments to less than $100,000,000. Any termination of the Revolving Credit Commitments below the L/C Sublimit or Swingline Sublimit then in effect shall reduce the L/C Sublimit or Swingline Sublimit, as applicable, by a like amount. The Administrative Agent shall give prompt notice to each Lender of any such termination of the Revolving Credit Commitments.

(b)     Reinstatement . Any termination of the Commitments pursuant to this Section 1.12 may not be reinstated.

Section 1.13.    Substitution of Lenders . In the event (a) the Borrower receives a claim from any Lender for compensation under Section 10.3 or 12.1 hereof, (b) the Borrower receives notice from any Lender of any illegality pursuant to Section 10.1 hereof, (c) any Lender is then a Defaulting Lender or such Lender is a Subsidiary or Affiliate of a Person who has been deemed insolvent or becomes the subject of a bankruptcy or insolvency proceeding or a receiver or conservator has been appointed for any such Person, or (d) a Lender fails to consent to an amendment or waiver requested to be consented to by all Lenders or all affected Lenders under Section 12.11 hereof at a time when the Required Lenders have approved such amendment or waiver (any such Lender referred to in clause (a), (b), (c), or (d) above being hereinafter referred to as an “Affected Lender” ), the Borrower may, in addition to any other rights the Borrower may have hereunder or under applicable law, require, at its expense, any such Affected Lender to assign, at par, without recourse, all of its interest, rights, and obligations hereunder (including all of its Commitments and the Loans and participation

interests in Letters of Credit and other amounts at any time owing to it hereunder and the other Loan Documents) to an Eligible Assignee specified by the Borrower, provided that (i) such assignment shall not conflict with or violate any law, rule or regulation or order of any court or other governmental authority, (ii) the Borrower shall have paid to the Affected Lender all monies (together with amounts due such Affected Lender under Section 1.11 hereof as if the Loans owing to it were prepaid rather than assigned) other than such principal owing to it hereunder, (iii) the assignment is entered into in accordance with, and subject to the consents required by, Section 12.10 hereof (provided any assignment fees and reimbursable expenses due thereunder shall be paid by the Borrower) and (iv) the assignee shall have consented to the proposed amendment or waivers not consented to by the Affected Lender.

Section 1.14.    Defaulting Lenders . (a)  Defaulting Lender Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as such Lender is no longer a Defaulting Lender, to the extent permitted by applicable law:

(i)     Waivers and Amendments . Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in Section 12.11 hereof.

(ii)     Defaulting Lender Waterfall . Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Section 9 or otherwise) or received by the Administrative Agent from a Defaulting Lender pursuant to Section 12.7 hereto shall be applied at such time or times as may be determined by the Administrative Agent as follows: first , to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent hereunder; second , to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to the L/C Issuer or the Swingline Lender hereunder; third , to Cash Collateralize the L/C Issuer’s Fronting Exposure with respect to such Defaulting Lender in accordance with Section 9.4; fourth , as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth , if so determined by the Administrative Agent and the Borrower, to be held in a deposit account and released pro rata in order to (x) satisfy such Defaulting Lender’s potential future funding obligations with respect to Loans under this Agreement and (y) Cash Collateralize the L/C Issuer’s future Fronting Exposure with respect to such Defaulting Lender with respect to future Letters of Credit issued under this Agreement, in accordance with Section 9.4; sixth , to the payment of any amounts owing to the Lenders, the L/C Issuer or the Swingline Lender as a result of any

judgment of a court of competent jurisdiction obtained by any Lender, the L/C Issuer or the Swingline Lender against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; seventh , so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and eighth , to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans or L/C Obligations in respect of which such Defaulting Lender has not fully funded its appropriate share, and (y) such Loans were made or the related Letters of Credit were issued at a time when the conditions set forth in Section 7.1 hereof were satisfied or waived, such payment shall be applied solely to pay the Loans of, and L/C Obligations owed to, all Non‑Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or L/C Obligations owed to, such Defaulting Lender until such time as all Loans and funded and unfunded participations in L/C Obligations and Swingline Loans are held by the Lenders pro rata in accordance with their Percentages of the relevant Commitments without giving effect to Section 1.14(a)(iv) below. Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 1.14(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(iii)     Certain Fees .

(A)    No Defaulting Lender shall be entitled to receive any commitment fee or facility fee, as applicable, for any period during which that Lender is a Defaulting Lender (and the Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender).

(B)    Each Defaulting Lender shall be entitled to receive L/C Participation Fees for any period during which that Lender is a Defaulting Lender only to the extent allocable to its Percentage of the stated amount of Letters of Credit for which it has provided Cash Collateral pursuant to Section 9.4 hereof.

(C)    With respect to any commitment fee, facility fee or L/C Participation Fee not required to be paid to any Defaulting Lender pursuant to clause (A) or (B) above, the Borrower shall (x) pay to each Non‑Defaulting Lender that portion of any such fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender’s participation in L/C Obligations or Swingline Loans that has

been reallocated to such Non‑Defaulting Lender pursuant to clause (iv) below, (y) pay to the L/C Issuer and Swingline Lender, as applicable, the amount of any such fee otherwise payable to such Defaulting Lender to the extent allocable to the L/C Issuer’s or Swingline Lender’s Fronting Exposure to such Defaulting Lender, and (z) not be required to pay the remaining amount of any such fee.

(iv)     Reallocation of Participations to Reduce Fronting Exposure . All or any part of such Defaulting Lender’s participation in L/C Obligations and Swingline Loans shall be reallocated among the Non‑Defaulting Lenders in accordance with their respective Percentages of the relevant Commitments (calculated without regard to such Defaulting Lender’s Commitments) but only to the extent that (x) the conditions set forth in Section 7.1 hereof are satisfied at the time of such reallocation, and (y) such reallocation does not cause the aggregate Revolving Loans and interests in L/C Obligations and Swingline Loans of any Non‑Defaulting Lender to exceed such Non‑Defaulting Lender’s Revolving Credit Commitment. No reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a Non‑Defaulting Lender as a result of such Non‑Defaulting Lender’s increased exposure following such reallocation.

(v)     Cash Collateral; Repayment of Swingline Loans . If the reallocation described in clause (iv) above cannot, or can only partially, be effected, the Borrower shall, without prejudice to any right or remedy available to them hereunder or under law, (x) first, prepay Swingline Loans in an amount equal to the Swing Lender’s Fronting Exposure and (y) second, Cash Collateralize the L/C Issuer’s Fronting Exposure in accordance with the procedures set forth in Section 9.4 hereof

(b)     Defaulting Lender Cure . If the Borrower, the Administrative Agent, the Swingline Lender and the L/C Issuer agree in writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), that Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit and Swingline Loans to be held pro rata by the Lenders in accordance with their respective Percentages of the relevant Commitments (without giving effect to Section 1.14(a)(iv) hereof), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided , further , that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender

will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

(c)     New Swingline Loans/Letters of Credit . So long as any Lender is a Defaulting Lender, (i) the Swingline Lender shall not be required to fund the Swingline Loans unless it is satisfied that it will have no Fronting Exposure after giving effect to the Swingline Loan and (ii) the L/C Issuer shall not be required to issue, extend, renew or increase any Letter of Credit unless it is satisfied that it will have no Fronting Exposure after giving effect thereto.

Any Incremental Term Loans made on an Increased Amount Date shall be designated a separate series (each, a “Series” ) of Incremental Term Loans for all purposes of this Agreement.

(b)     Conditions to Incremental Loans.

(b)    All amounts prepaid pursuant to subsection (a) above shall be held by the Administrative Agent in one or more separate collateral accounts (each such account, and the credit balances, properties, and any investments from time to time held therein, and any substitutions for such account, any certificate of deposit or other instrument evidencing any of the foregoing and all proceeds of and earnings on any of the foregoing being collectively called the “Collateral Account” ) as security for, and for application by the Administrative Agent (to the extent available) to, the reimbursement of any payment under any Letter of Credit then or thereafter made by the L/C Issuer, and to the payment of the unpaid balance of all other Obligations (and to all Hedging Liability and Bank Product Obligations).

(i)     Grant of Security Interest . The Borrower, and to the extent provided by any Defaulting Lender, such Defaulting Lender, hereby grant to the Administrative Agent, for the benefit of the L/C Issuer, and agree to maintain, a first priority security interest in all such Cash Collateral as security for such Defaulting Lender’s obligation to fund participations in respect of L/C Obligations, to be applied pursuant to clause (ii) below. If at any time the Administrative Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Administrative Agent and the L/C Issuer as herein provided (other than Permitted Liens), or that the total amount of such Cash Collateral is less than the Minimum Collateral Amount, the Borrower shall, promptly upon demand by the Administrative Agent, pay or provide to the Administrative Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency (after giving effect to any Cash Collateral provided by the Defaulting Lender).

(ii)     Application . Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under this Section 9.4 or Section 1.14 in respect of Letters of Credit shall be applied to the satisfaction of the Defaulting Lender’s obligation to fund participations in respect of L/C Obligations (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) for which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for herein.

(iii)     Termination of Requirement . Cash Collateral (or the appropriate portion thereof) provided to reduce the L/C Issuer’s Fronting Exposure shall no longer be required to be held as Cash Collateral pursuant to this Section 9.4(c) following (A) the elimination of the applicable Fronting Exposure (including by the termination of Defaulting Lender status of the applicable Lender), or (B) the determination by the Administrative Agent and the L/C Issuer that there exists excess Cash Collateral; provided that, subject to Section 1.14 the Person providing Cash Collateral and the L/C Issuer may agree that Cash Collateral shall be held to support future anticipated Fronting Exposure or other obligations and provided further that to the extent that such Cash Collateral was provided by the Borrower, such Cash Collateral shall remain subject to the security interest granted pursuant to the Loan Documents.

Section 9.5.    Notice of Default . The Administrative Agent shall give notice to the Borrower under Section 9.1(c) hereof promptly upon being requested to do so by any Lender and shall thereupon notify all the Lenders thereof.

Notwithstanding any other provisions of this Agreement or any other Loan Document, if at any time any Change in Law makes it unlawful for any Lender to make or continue to maintain any Eurodollar Loans or to perform its obligations as contemplated hereby related to Eurodollar Loans, such Lender shall promptly give written notice thereof to the Borrower and such Lender’s obligations to make or maintain Eurodollar Loans under this Agreement shall be suspended until it is no longer unlawful for such Lender to make or maintain Eurodollar Loans. The Borrower shall prepay on demand the outstanding principal amount of any such affected Eurodollar Loans, together with all interest accrued thereon and all other amounts then due and payable to such Lender under this Agreement; provided, however, subject to all of the terms and conditions of this Agreement, the Borrower may then elect to borrow the principal amount of the affected Eurodollar Loans from such Lender by means of Base Rate Loans from such Lender, which Base Rate Loans shall not be made ratably by the Lenders but only from such affected Lender.

Section 10.2.    Unavailability of Deposits or Inability to Ascertain, or Inadequacy of, LIBOR . If on or prior to the first day of any Interest Period for any Borrowing of Eurodollar Loans:

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

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

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

Section 10.3.    Increased Cost and Reduced Return .     (a)     Increased Costs Generally. If any Change in Law shall:

(i)    impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement reflected in the Adjusted LIBOR) or the L/C Issuer;

(ii)    subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (b) through (d) of the definition of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or

(iii)    impose on any Lender or the L/C Issuer or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender or such other Recipient of making, converting to, continuing or maintaining any Loan or of maintaining its obligation to make any such Loan, or to increase the cost to such Lender, the L/C Issuer or such other Recipient of participating in, issuing or maintaining any Letter of Credit or Swingline Loan (or of maintaining its obligation to participate in or to issue any Letter of Credit or Swingline Loan), or to reduce the amount of any sum received or receivable by such Lender, the L/C Issuer or other Recipient hereunder (whether of principal, interest or any other amount) then, within fifteen (15) days after request of such Lender, the L/C Issuer or other Recipient, the Borrower will pay to such Lender, the L/C Issuer or other Recipient (with a copy to the Administrative Agent), as the case may be, such additional amount or amounts as will compensate such Lender, the L/C Issuer or other Recipient, as the case may be, for such additional costs incurred or reduction suffered.

(b)     Capital Requirements. If any Lender or the L/C Issuer determines that any Change in Law affecting such Lender or the L/C Issuer or any lending office of such Lender or such Lender’s or the L/C Issuer’s holding company, if any, regarding capital or liquidity requirements, has or would have the effect of reducing the rate of return on such Lender’s or the L/C Issuer’s capital or on the capital of such Lender’s or the L/C Issuer’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, or participations in Letters of Credit or Swingline Loans held by, such Lender, or the Letters of Credit issued by the L/C Issuer, to a level below that which such Lender or the L/C Issuer or such Lender’s or the L/C Issuer’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or the L/C Issuer’s policies and the policies of such Lender’s or the L/C Issuer’s holding company with respect to capital adequacy and liquidity), then from time to time within fifteen (15) days after request by such Lender, the L/C Issuer or other Recipient (with a copy to the Administrative Agent), the Borrower will pay to such Lender or the L/C Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or the L/C Issuer or such Lender’s or the L/C Issuer’s holding company for any such reduction suffered.

(c)     Certificates for Reimbursement. A certificate of a Lender or the L/C Issuer setting forth the amount or amounts necessary to compensate such Lender or the L/C Issuer or its holding company, as the case may be, as specified in subsection (a) or (b) of this Section and delivered to the Borrower, shall be conclusive absent manifest error. The Borrower shall pay such Lender or the L/C Issuer, as the case may be, the amount shown as due on any such certificate within fifteen (15) days after receipt thereof.

(d)     Delay in Requests. Failure or delay on the part of any Lender or the L/C Issuer to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or the L/C Issuer’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or the L/C Issuer pursuant to this Section for any increased costs incurred or reductions suffered more than nine (9) months prior to the date that such Lender or the L/C Issuer, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions, and of such Lender’s or the L/C Issuer’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the nine‑month period referred to above shall be extended to include the period of retroactive effect thereof).

Section 10.4.    Lending Offices . Each Lender may, at its option, elect to make its Loans hereunder at the branch, office or affiliate specified on the appropriate signature page hereof (each a “Lending Office” ) for each type of Loan available hereunder or at such other of its branches, offices or affiliates as it may from time to time elect and designate in a written notice to the Borrower and the Administrative Agent. To the extent reasonably possible, a Lender shall designate an

alternative branch or funding office with respect to its Eurodollar Loans to reduce any liability of the Borrower to such Lender under Section 10.3 hereof or to avoid the unavailability of Eurodollar Loans under Section 10.2 hereof, so long as such designation is not otherwise disadvantageous to the Lender.

Section 10.5.    Discretion of Lender as to Manner of Funding . Notwithstanding any other provision of this Agreement, each Lender shall be entitled to fund and maintain its funding of all or any part of its Loans in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder with respect to Eurodollar Loans shall be made as if each Lender had actually funded and maintained each Eurodollar Loan through the purchase of deposits in the interbank eurodollar market having a maturity corresponding to such Loan’s Interest Period, and bearing an interest rate equal to LIBOR for such Interest Period.

Section 11.1.    Appointment and Authority     . Each of the Lenders and the L/C Issuer hereby irrevocably appoints Bank of Montreal to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Section 11 are solely for the benefit of the Administrative Agent, the Lenders and the L/C Issuer, and neither the Borrower nor any other Loan Party shall have rights as a third‑party beneficiary of any of such provisions. It is understood and agreed that the use of the term “agent” herein or in any other Loan Documents (or any other similar term) with reference to the 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 as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties.

Section 11.2.    Rights as a Lender     . The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent, and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for, and generally engage in any kind of business with, the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

Section 11.3.    Action by Administrative Agent; Exculpatory Provisions . (a) If the Administrative Agent receives from the Borrower a written notice of an Event of Default or if the L/C Issuer or any Lender shall notify Administrative Agent of the existence of a Default or Event of Default, the Administrative Agent shall promptly give each of the Lenders and the L/C Issuer written notice thereof. The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Administrative Agent and its Related Parties:

(i)    shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing;

(ii)    shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents), provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or applicable law, including for the avoidance of doubt any action that may be in violation of the automatic stay under any Debtor Relief Law or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any Debtor Relief Law. The Administrative Agent shall in all cases be fully justified in failing or refusing to act hereunder or under any other Loan Document unless it first receives any further assurances of its indemnification from the Lenders that it may require, including prepayment of any related expenses and any other protection it requires against any and all costs, expense, and liability which may be incurred by it by reason of taking or continuing to take any such action; and

(iii)    shall not, except as expressly set forth herein and in the other Loan Documents, have any duty or responsibility to disclose, and shall not be liable for the failure to disclose, any information relating to any Loan Party or any of its Affiliates that is communicated to or obtained by the Person serving as the Administrative Agent or any of its Affiliates in any capacity.

(b)    Neither the Administrative Agent nor any of its Related Parties shall be liable for any action taken or not taken by the Administrative Agent under or in connection with this Agreement or any other Loan Document or the transactions contemplated hereby or thereby (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as

shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 9.2, 9.3, 9.4, 9.5 and 12.11), or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and nonappealable judgment. Any such action taken or failure to act pursuant to the foregoing shall be binding on all Lenders. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until notice describing such Default is given to the Administrative Agent in writing by the Borrower, a Lender, or the L/C Issuer.

(c)    Neither the Administrative Agent nor any of its Related Parties shall be responsible for or have any duty or obligation to any Lender or the L/C Issuer or participant or any other Person to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Section 7.1 or 7.2 or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

Section 11.4.    Reliance by Administrative Agent     . The Administrative Agent shall be entitled to rely upon, and shall be fully protected in relying and shall not incur any liability for relying upon, any notice, request, certificate, communication, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall be fully protected in relying and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance, extension, renewal or increase of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or the L/C Issuer, the Administrative Agent may presume that such condition is satisfactory to such Lender or the L/C Issuer unless the Administrative Agent shall have received notice to the contrary from such Lender or the L/C Issuer prior to the making of such Loan or the issuance of such Letter of Credit. The Administrative Agent may consult with legal counsel (who may be counsel for the Loan Parties), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Section 11.5.    Delegation of Duties     . The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub‑agents appointed by the Administrative Agent. The Administrative Agent and any such sub‑agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Section shall apply to any such sub‑agent and to the Related Parties of the Administrative Agent and any such sub‑agent, and shall apply to their respective activities in connection with the syndication of the Credits as well as activities as Administrative Agent. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub‑agents except to the extent that a court of competent jurisdiction determines in a final and nonappealable judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub‑agents.

Section 11.6.    Resignation of Administrative Agent     . (a) The Administrative Agent may at any time give notice of its resignation to the Lenders, the L/C Issuer and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor, which shall be a bank with an office in the United States of America, or an Affiliate of any such bank with an office in the United States of America. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent gives notice of its resignation (or such earlier day as shall be agreed by the Required Lenders) (the “Resignation Effective Date” ), then the retiring Administrative Agent may (but shall not be obligated to), on behalf of the Lenders and the L/C Issuer, appoint a successor Administrative Agent meeting the qualifications set forth above. Whether or not a successor has been appointed, such resignation shall become effective in accordance with such notice on the Resignation Effective Date.

(b)    With effect from the Resignation Effective Date, (i) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents, and (ii) except for any indemnity payments owed to the retiring or removed Administrative Agent, all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender and the L/C Issuer directly, until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided for above. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring Administrative Agent (other than any rights to indemnity payments or other amounts owed to the retiring Administrative Agent), and the retiring Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring Administrative Agent’s resignation hereunder and under the other Loan Documents, the

provisions of this Section 11 and Section 12.13 shall continue in effect for the benefit of such retiring Administrative Agent, its sub‑agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Administrative Agent was acting as Administrative Agent.

Section 11.7.    Non‑Reliance on Administrative Agent and Other Lenders     . Each Lender and the L/C Issuer acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender and the L/C Issuer also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

Section 11.8.    L/C Issuer and Swingline Lender. The L/C Issuer shall act on behalf of the Lenders with respect to any Letters of Credit issued by it and the documents associated therewith, and the Swingline Lender shall act on behalf of the Lenders with respect to the Swingline Loans made hereunder. The L/C Issuer and the Swingline Lender shall each have all of the benefits and immunities (i) provided to the Administrative Agent in this Section 11 with respect to any acts taken or omissions suffered by the L/C Issuer in connection with Letters of Credit issued by it or proposed to be issued by it and the Applications pertaining to such Letters of Credit or by the Swingline Lender in connection with Swingline Loans made or to be made hereunder as fully as if the term “Administrative Agent”, as used in this Section 11, included the L/C Issuer and the Swingline Lender with respect to such acts or omissions and (ii) as additionally provided in this Agreement with respect to the L/C Issuer or Swingline Lender, as applicable. Any resignation by the Person then acting as Administrative Agent pursuant to Section 11.6 shall also constitute its resignation or the resignation of its Affiliate as the L/C Issuer and Swingline Lender except as it may otherwise agree. If such Person then acting as the L/C Issuer so resigns, it shall retain all the rights, powers, privileges and duties of the L/C Issuer hereunder with respect to all Letters of Credit outstanding as of the effective date of its resignation as the L/C Issuer and all L/C Obligations with respect thereto, including the right to require the Lenders to make Loans or fund risk participations in Reimbursement Obligations pursuant to Section 1.3. If such Person then acting as Swingline Lender resigns, it shall retain all the rights of the Swingline Lender provided for hereunder with respect to Swingline Loans made by it and outstanding as of the effective date of such resignation, including the right to require the Lenders to make Loans or fund risk participations in outstanding Swingline Loans pursuant to Section 1.2(b). Upon the appointment by the Borrower of a successor L/C Issuer or Swingline Lender hereunder (which successor shall in all cases be a Lender other than a Defaulting Lender),

(i) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring L/C Issuer or Swingline Lender, as applicable (other than any rights to indemnity payments or other amounts that remain owing to the retiring L/C Issuer or Swingline Lender), and (ii) the retiring L/C Issuer and Swingline Lender shall be discharged from all of their respective duties and obligations hereunder or under the other Loan Documents other than with respect to its outstanding Letters of Credit and Swingline Loans, and (iii) upon the request of the resigning L/C Issuer, the successor L/C Issuer shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to the resigning L/C Issuer to effectively assume the obligations of the resigning L/C Issuer with respect to such Letters of Credit.

Section 11.9.    Hedging Liability and Bank Product Obligations . By virtue of a Lender’s execution of this Agreement or an assignment agreement pursuant to Section 12.10 hereof, as the case may be, any Affiliate of such Lender with whom the Borrower or any other Loan Party has entered into an agreement creating Hedging Liability or Bank Product Obligations shall be deemed a Lender party hereto for purposes of any reference in a Loan Document to the parties for whom the Administrative Agent is acting, it being understood and agreed that the rights and benefits of such Affiliate under the Loan Documents consist exclusively of such Affiliate’s right to share in payments and collections out of the Guaranties as more fully set forth in Section 3.1. In connection with any such distribution of payments and collections, or any request for the release of the Guaranties in connection with the termination of the Commitments and the payment in full of the Obligations, the Administrative Agent shall be entitled to assume no amounts are due to any Lender or its Affiliate with respect to Hedging Liability or Bank Product Obligations unless such Lender has notified the Administrative Agent in writing of the amount of any such liability owed to it or its Affiliate prior to such distribution or payment or release of Guaranties.

Section 11.10.    Designation of Additional Agents . The Administrative Agent shall have the continuing right, for purposes hereof, at any time and from time to time to designate one or more of the Lenders (and/or its or their Affiliates) as “syndication agents,” “documentation agents,” “book runners,” “lead arrangers,” “arrangers,” or other designations for purposes hereto, but such designation shall have no substantive effect, and such Lenders and their Affiliates shall have no additional powers, duties or responsibilities as a result thereof.

Section 11.11.    Authorization to Release Guaranties      . The Administrative Agent is hereby irrevocably authorized by each of the Lenders, the L/C Issuer, and their Affiliates to release any Material Subsidiary from its obligations as a Guarantor, at any time or from time to time, if (i) such Person ceases to be a Material Subsidiary as a result of a transaction permitted under the Loan Documents or (ii) the requirements of Section 4.3 hereof are met. Upon the Administrative Agent’s

request, the Required Lenders will confirm in writing the Administrative Agent’s authority to release any Person form its obligations as a Guarantor under the Loan Documents.

Section 11.12.    Authorization of Administrative Agent to File Proofs of Claim      In case of the pendency of any proceeding under any Debtor Relief Law or any other judicial proceeding relative to any Loan Party, the Administrative Agent (irrespective of whether the principal of any Loan or L/C Obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise:

(a)    to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, L/C Obligations and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of Lenders, the L/C Issuer and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the L/C Issuer and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders, the L/C Issuer and the Administrative Agent under the Loan Documents including, but not limited to, Sections 1.11, 2.1, 10.3 and 12.13) allowed in such judicial proceeding; and

(b)    to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender and the L/C Issuer to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders and the L/C Issuer, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Sections 2.1 and 12.13. Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender or the L/C Issuer any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender or the L/C Issuer or to authorize the Administrative Agent to vote in respect of the claim of any Lender or the L/C Issuer in any such proceeding.

SECTION 12.        MISCELLANEOUS.

Section 12.1.    Taxes . (a)  Payments Free of Withholding .

(a)     Certain Defined Terms. For purposes of this Section, the term “Lender” includes the L/C Issuer and the term “applicable law” includes FATCA.

(b)     Payments Free of Taxes. Any and all payments by or on account of any obligation of any Loan Party under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by the applicable Loan Party shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made.

(c)     Payment of Other Taxes by the Loan Parties. The Loan Parties shall timely pay to the relevant Governmental Authority in accordance with applicable law, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes.

(d)     Indemnification by the Loan Parties. The Loan Parties shall jointly and severally indemnify each Recipient, within ten (10) days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(e)     Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent, within ten (10) days after demand therefor, for (i) any Indemnified Taxes or Other Taxes attributable to such Lender (but only to the extent that any Loan Party has not already indemnified the Administrative Agent for such Indemnified Taxes or Other Taxes and without limiting the obligation of the Loan Parties to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 12.10(d) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable

expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this subsection (e).

(f)     Evidence of Payments. As soon as practicable after any payment of Taxes by any Loan Party to a Governmental Authority pursuant to this Section, such Loan Party shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(g)     Status of Lenders. (i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 12.1(g)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(ii)    Without limiting the generality of the foregoing,

(A)    any Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed originals of IRS Form W‑9 certifying that such Lender is exempt from U.S. federal backup withholding tax;

(B)    any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), whichever of the following is applicable:

(i)    in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed originals of IRS Form W‑8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W‑8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

(ii)    executed originals of IRS Form W‑8ECI;

(iii)    in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit I‑1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate” ) and (y) executed originals of IRS Form W‑8BEN; or

(iv)    to the extent a Foreign Lender is not the beneficial owner, executed originals of IRS Form W‑8IMY, accompanied by IRS Form W‑8ECI, IRS Form W‑8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit I‑2 or Exhibit I‑3, IRS Form W‑9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit I‑4 on behalf of each such direct and indirect partner;

(C)    any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender

under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed originals of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and

(D)    if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so.

(h)     Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section (including by the payment of additional amounts pursuant to this Section), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out‑of‑pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this subsection (h) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this subsection (h), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this subsection (h) the payment of which would place the indemnified party in a less favorable net after‑Tax position than the indemnified party would have

been in if the Tax subject to indemnification had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts giving rise to such refund had never been paid. This subsection shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(i)     Survival. Each party’s obligations under this Section shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document.

Section 12.2.    Other Taxes. The Borrower agrees to pay on demand, and indemnify and hold the Administrative Agent, the Lenders, and the L/C Issuer harmless from, any Other Taxes payable in respect of this Agreement or any other Loan Document, including interest and penalties, in the event any such taxes are assessed, irrespective of when such assessment is made and whether or not any credit is then in use or available hereunder.

Section 12.3.    No Waiver, Cumulative Remedies. No delay or failure on the part of the Administrative Agent, the L/C Issuer, or any Lender, or on the part of the holder or holders of any of the Obligations, in the exercise of any power or right under any Loan Document shall operate as a waiver thereof or as an acquiescence in any default, nor shall any single or partial exercise of any power or right preclude any other or further exercise thereof or the exercise of any other power or right. The rights and remedies hereunder of the Administrative Agent, the L/C Issuer, the Lenders, and of the holder or holders of any of the Obligations are cumulative to, and not exclusive of, any rights or remedies which any of them would otherwise have.

Section 12.4.    Non‑Business Days. If any payment hereunder becomes due and payable on a day which is not a Business Day, the due date of such payment shall be extended to the next succeeding Business Day on which date such payment shall be due and payable. In the case of any payment of principal falling due on a day which is not a Business Day, interest on such principal amount shall continue to accrue during such extension at the rate per annum then in effect, which accrued amount shall be due and payable on the next scheduled date for the payment of interest.

Section 12.5.    Survival of Representations. All representations and warranties made herein or in any other Loan Document or in certificates given pursuant hereto or thereto shall survive the execution and delivery of this Agreement and the other Loan Documents, and shall continue in full force and effect with respect to the date as of which they were made as long as any credit is in use or available hereunder.

Section 12.6.      Survival of Indemnities . All indemnities and other provisions relative to reimbursement to the Lenders and the L/C Issuer of amounts sufficient to protect the yield of the Lenders and the L/C Issuer with respect to the Loans and Letters of Credit, including, but not limited to, Sections 1.11, 10.3, and 12.13 hereof, shall survive the termination of this Agreement and the other Loan Documents and the payment of the Obligations.

Section 12.7.    Sharing of Payments by Lenders. If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or other obligations hereunder resulting in such Lender receiving payment of a proportion of the aggregate amount of its Loans and accrued interest thereon or other such obligations greater than its pro rata share thereof as provided herein, then the Lender receiving such greater proportion shall (a) notify the Administrative Agent of such fact, and (b) purchase (for cash at face value) participations in the Loans and such other obligations of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and other amounts owing them; provided that:

(a)    if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest; and

(b)    the provisions of this Section shall not be construed to apply to (x) any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender), or (y) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in L/C Obligations to any assignee or participant, other than to any Loan Party or any Subsidiary thereof (as to which the provisions of this Section shall apply).

Each Loan Party consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against each Loan Party rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of each Loan Party in the amount of such participation.

Section 12.8.    Notices; Electronic Communication . (a)  Notices Generally. Except as otherwise specified herein, all notices hereunder and under the other Loan Documents shall be in writing (including, without limitation, notice by telecopy) and shall be given to the relevant party at its address or telecopier number set forth below, or such other address or telecopier number as

such party may hereafter specify by notice to the Administrative Agent and the Borrower given by courier, by United States certified or registered mail, by telecopy or by other telecommunication device capable of creating a written record of such notice and its receipt. Notices under the Loan Documents to any Lender shall be addressed to its address or telecopier number set forth on its Administrative Questionnaire; and notices under the Loan Documents to the Borrower, any Guarantor the Administrative Agent, or the L/C Issuer shall be addressed to its respective address or telecopier number set forth below:

Each such notice, request or other communication shall be effective (i) if given by telecopier, when such telecopy is transmitted to the telecopier number specified in this Section or in the relevant Administrative Questionnaire and a confirmation of such telecopy has been received by the sender, (ii) if given by mail, 5 days after such communication is deposited in the mail, certified or registered with return receipt requested, addressed as aforesaid or (iii) if given by any other means, when delivered at the addresses specified in this Section or in the relevant Administrative Questionnaire; provided that any notice given pursuant to Section 1 hereof shall be effective only upon receipt.

(b)     Electronic Communications . Notices and other communications to the Lenders and the L/C Issuer hereunder may be delivered or furnished by electronic communication (including e mail and Internet or intranet websites) pursuant to procedures approved by the Administrative Agent, provided that the foregoing shall not apply to notices to any Lender or the L/C Issuer pursuant to

Section 1.3(f) or Section 1.6 if such Lender or the L/C Issuer, as applicable, has notified the Administrative Agent that it is incapable of receiving notices under such respective Section by electronic communication. The Administrative Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved by it, provided that approval of such procedures may be limited to particular notices or communications.

Unless the Administrative Agent otherwise prescribes, (i) notices and other communications sent to an e-mail address shall be deemed received upon the sender’s receipt of an acknowledgement from the intended recipient (such as by the “return receipt requested” function, as available, return e-mail or other written acknowledgement), and (ii) notices or communications posted to an Internet or intranet website shall be deemed received upon the deemed receipt by the intended recipient, at its e-mail address as described in the foregoing clause (i), of notification that such notice or communication is available and identifying the website address therefore, provided that, for both clauses (i) and (ii) above, if such notice, email or other communication is not sent during the normal business hours of the recipient, such notice, email or communication shall be deemed to have been sent at the opening of business on the next business day for the recipient.

Section 12.9.    Counterparts; Integration; Effectiveness . (a) Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and the other Loan Documents, and any separate letter agreements with respect to fees payable to the Administrative Agent, constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 7.2, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or in electronic (e.g., “pdf” or “tif”) format shall be effective as delivery of an original executed counterpart of this Agreement. For purposes of determining compliance with the conditions specified in Section 7.2 hereof, each Lender and the L/C Issuer that has signed this Agreement shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter required thereunder to be consented to or approved by or acceptable or satisfactory to a Lender or the L/C Issuer unless the Administrative Agent shall have received notice from such Lender or the L/C Issuer prior to the Closing Date specifying its objection thereto.

(b)     Electronic Execution of Assignments. The words “execution,” “signed,” “signature,” and words of like import in any Assignment and Assumption shall be deemed to include electronic

signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper‑based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the Illinois State Electronic Commerce Security Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

Section 12.10.    Successors and Assigns .

(a)     Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that neither the Borrower nor any other Loan Party may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each Lender, and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the provisions of paragraph (d) of this Section, or (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (e) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in paragraph (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b)     Assignments by Lenders. Any Lender may at any time assign to one or more assignees all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitments and the Loans at the time owing to it); provided that (in each case with respect to any Credit) any such assignment shall be subject to the following conditions:

(i)     Minimum Amounts. (A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitments and the Loans at the time owing to it (in each case with respect to any Credit) or contemporaneous assignments to related Approved Funds that equal at least the amount specified in paragraph (b)(i)(B) of this Section in the aggregate or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and

(B)    in any case not described in paragraph (b)(i)(A) of this Section, the aggregate amount of the relevant Commitment (which for this purpose includes Loans outstanding

thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $5,000,000, unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed).

(ii)     Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loan or the Commitment assigned, except that this clause (ii) shall not prohibit any Lender from assigning all or a portion of its rights and obligations among separate Credits on a non‑pro rata basis.

(iii)     Required Consents. No consent shall be required for any assignment except to the extent required by paragraph (b)(i)(B) of this Section and, in addition:

(A)    the consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (x) an Event of Default has occurred and is continuing at the time of such assignment, or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund; provided that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within five (5) Business Days after having received notice thereof;

(B)    the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required for assignments in respect of (i) the Revolving Credit or any unfunded Commitments with respect to any Term Credit if such assignment is to a Person that is not a Lender with a Commitment in respect of such Credit, an Affiliate of such Lender or an Approved Fund with respect to such Lender, or (ii) any Term Loans to a Person who is not a Lender, an Affiliate of a Lender or an Approved Fund; and

(C)    the consent of the L/C Issuer (such consent not to be unreasonably withheld or delayed) and Swingline Lender (such consent not to be unreasonably withheld or delayed) shall be required for any assignment in respect of the Revolving Credit.

(iv)     Assignment and Assumption. The parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; provided that the Administrative Agent may, in its sole discretion, elect to waive such processing and recordation fee in the case of any assignment . The assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

(v)     No Assignment to Certain Persons. No such assignment shall be made to (A) the Borrower or any other Loan Party or any Loan Party’s Affiliates or Subsidiaries or (B) to any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (B).

(vi)     No Assignment to Natural Persons or Borrower or Borrower’s Affiliates. No such assignment shall be made to a natural Person, the Borrower, any Guarantor or any of the Borrower’s or such Guarantor’s Affiliates or Subsidiaries.

(vii)     Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Borrower and the Administrative Agent, the applicable pro rata share of Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent, the L/C Issuer, the Swingline Lender and each other Lender hereunder (and interest accrued thereon), and (y) acquire (and fund as appropriate) its full pro rata share of all Loans and participations in Letters of Credit and Swingline Loans in accordance with its Percentage. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under applicable law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by

such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 12.13 and 12.14 with respect to facts and circumstances occurring prior to the effective date of such assignment; provided that except to the extent otherwise expressly agreed by the affected parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (d) of this Section.

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

(d)     Participations. Any Lender may at any time, without the consent of, the Borrower or the Administrative Agent but with notice to the Borrower of the identity of any such participant and amount of such participation, sell participations to any Person (other than a natural Person or the Borrower or any other Loan Party or any Loan Party’s Affiliates or Subsidiaries) (each, a “Participant” ) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitments and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) except to the extent provided in this Section 12.10, such participation shall not entitle such participant to any rights or privileges under this Agreement, (iv) except to the extent provided in this Section 12.10, such participant shall have no direct rights against the Loan Parties and (v) the Borrower, the Administrative Agent, the L/C Issuer and Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. For the avoidance of doubt, each Lender shall be responsible for the indemnity under Section 11.8 with respect to any payments made by such Lender to its Participant(s).

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in Section 12.11 that expressly relate to amendments requiring the unanimous consent of the Lenders, or of all affected Lenders, in the Credit in which such Participant participates. The Borrower agrees that each Participant shall be entitled to the benefits of Sections 1.11, 10.3 and 12.1 (subject to the requirements and limitations therein, including the requirements under Section 12.1(g) (it being understood that the documentation required under Section 12.1(g) shall be delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section; provided that such Participant (A) agrees to be subject to the provisions of Sections 1.13 and 10.4 as if it were an assignee under paragraph (b) of this Section; and (B) shall not be entitled to receive any greater payment under Sections 10.3 or 12.1, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrower’s request and Participant’s expense, to use reasonable efforts to cooperate with the Borrower to effectuate the provisions of Section 1.13 with respect to any Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 12.14 as though it were a Lender; provided that such Participant agrees to be subject to Section 12.7 as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a non‑fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register” ); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103‑1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(e)     Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such

pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

Section 12.11.    Amendments. Any provision of this Agreement or the other Loan Documents may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by (a) the Borrower, (b) the Required Lenders, and (c) if the rights or duties of the Administrative Agent, the L/C Issuer or the Swingline Lender are affected thereby, the Administrative Agent, the L/C Issuer or the Swingline Lender, as applicable; provided that:

(i)    no amendment or waiver pursuant to this Section 12.11 shall (A) increase or extend any Commitment of any Lender without the consent of such Lender or (B) reduce the amount of or postpone the date for any scheduled payment of any principal of or interest on any Loan or of any Reimbursement Obligation or of any fee payable hereunder without the consent of the Lender to which such payment is owing or which has committed to make such Loan or Letter of Credit (or participate therein) hereunder (including, specifically, any change in the manner of computation of any financial covenant (including any defined terms with respect thereto) used in determining the Applicable Margin that would result in a reduction of any interest rate without the written consent of each Lender affected thereby), or (C) release the Borrower or any Guarantor (except as expressly provided herein) without the consent of each Lender;

(ii)    no amendment or waiver pursuant to this Section 12.11 shall, unless signed by each Lender affected thereby, extend the Revolving Credit Termination Date, extend the Term A Credit Termination Date, extend the Term B Credit Termination Date, change the definition of “Required Lenders” or “Percentage,” change the provisions of Section 2.1, the pro rata sharing provisions of Sections 3.1 and 12.7 or this Section 12.11, or affect the number of Lenders required to take any action hereunder or under any other Loan Document; and

(iii)    no amendment to Section 13 hereof shall be made without the consent of the Guarantors affected thereby.

Notwithstanding anything to the contrary herein, (1) no Defaulting Lender shall have any right to approve or disapprove any amendment, waiver or consent hereunder (and any amendment, waiver or consent which by its terms requires the consent of all Lenders or each affected Lender may be effected with the consent of the applicable Lenders other than Defaulting Lenders) and such Defaulting Lender’s Commitments shall be excluded for purposes of determining “Required Lenders”, except that (x) the Commitment of any Defaulting Lender may not be increased or extended without the consent of such Lender and (y) any waiver, amendment or modification

requiring the consent of all Lenders or each affected Lender that by its terms affects any Defaulting Lender more adversely than other affected Lenders shall require the consent of such Defaulting Lender, (2) if the Administrative Agent and the Borrower have jointly identified an obvious error or any error or omission of a technical nature, in each case, in any provision of the Loan Documents, then the Administrative Agent and the Borrower shall be permitted to amend such provision, (3) guarantees, collateral security documents and related documents executed by the Borrower or any other Loan Party in connection with this Agreement may be in a form reasonably acceptable to the Administrative Agent and may be amended, supplemented or waived without the consent of any Lender if such amendment, supplement or waiver is delivered in order to (x) comply with local law or advice of local counsel, (y) cure ambiguities, omissions, mistakes or defects or (z) cause such guarantee, collateral security document or other document to be consistent with this Agreement and the other Loan Documents, and (4) the Borrower and the Administrative Agent may, without the input or consent of any other Lender, effect amendments to this Agreement and the other Loan Documents as may be necessary in the reasonable opinion of the Borrower and the Administrative Agent to effect the provisions of Section 1.16.

Section 12.12.    Headings. Section headings used in this Agreement are for reference only and shall not affect the construction of this Agreement.

Section 12.13.    Costs and Expenses; Indemnification . (a) The Borrower agrees to pay all reasonable costs and expenses of the Administrative Agent in connection with the preparation, negotiation, and administration of the Loan Documents, including, without limitation, the reasonable fees and disbursements of counsel to the Administrative Agent, in connection with the preparation and execution of the Loan Documents, and any amendment, waiver or consent related thereto, whether or not the transactions contemplated herein are consummated. The Borrower agrees to pay to the Administrative Agent, the L/C Issuer, and each Lender, and any other holder of any Obligations outstanding hereunder, all costs and expenses reasonably incurred or paid by the Administrative Agent, the L/C Issuer, such Lender, or any such holder, including reasonable attorneys’ fees and disbursements and court costs, in connection with any Default or Event of Default hereunder or in connection with the enforcement of any of the Loan Documents (including all such costs and expenses incurred in connection with any proceeding under the United States Bankruptcy Code involving the Borrower or any Guarantor as a debtor thereunder). The Borrower further agrees to indemnify the Administrative Agent, the L/C Issuer, each Lender, and any security trustee therefor, and their respective directors, officers, employees, agents, financial advisors, and consultants (each such Person being called an “Indemnitee” ) against all losses, claims, damages, penalties, judgments, liabilities and expenses (including, without limitation, all reasonable fees and disbursements of counsel for any such Indemnitee and all reasonable expenses of litigation or preparation therefor, whether or not the Indemnitee is a party thereto, or any settlement arrangement arising from or relating to any such litigation) which any of them may pay or incur arising out of or relating to any

Loan Document or any of the transactions contemplated thereby or the direct or indirect application or proposed application of the proceeds of any Loan or Letter of Credit, other than those which arise from the gross negligence or willful misconduct of the party claiming indemnification, as determined in a final, non‑appealable judgment by a court of competent jurisdiction. The Borrower, upon demand by the Administrative Agent, the L/C Issuer, or a Lender at any time, shall reimburse the Administrative Agent, the L/C Issuer, or such Lender for any reasonable legal or other expenses (including, without limitation, all reasonable fees and disbursements of counsel for any such Indemnitee) incurred in connection with investigating or defending against any of the foregoing (including any settlement costs relating to the foregoing) except if the same is directly due to the gross negligence or willful misconduct of the party to be indemnified, as determined in a final, non-appealable judgment by a court of competent jurisdiction. To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or the other Loan Documents or any agreement or instrument contemplated hereby or thereby, the transactions contemplated hereby or thereby, any Loan or Letter of Credit or the use of the proceeds thereof. The obligations of the Borrower under this Section shall survive the termination of this Agreement.

(b)    The Borrower unconditionally agrees to indemnify, defend and hold harmless, and covenants not to sue for any claim for contribution against, each Indemnitee for any damages, costs, loss or expense, including without limitation, response, remedial or removal costs and all fees and disbursements of counsel for any such Indemnitee, arising out of any of the following: (i) any presence, release, threatened release or disposal of any hazardous or toxic substance or petroleum by Whitestone REIT, the Borrower or any Subsidiary or otherwise occurring on or with respect to its Property (whether owned or leased), (ii) the operation or violation of any environmental law, whether federal, state, or local, and any regulations promulgated thereunder, by Whitestone REIT, the Borrower or any Subsidiary or otherwise occurring on or with respect to its Property (whether owned or leased), (iii) any claim for personal injury or property damage in connection with Whitestone REIT, the Borrower or any Subsidiary or otherwise occurring on or with respect to its Property (whether owned or leased), and (iv) the inaccuracy or breach of any environmental representation, warranty or covenant by Whitestone REIT, the Borrower or any Subsidiary made herein or in any other Loan Document evidencing or securing any Obligations or setting forth terms and conditions applicable thereto or otherwise relating thereto, except for damages arising from the willful misconduct or gross negligence of the relevant Indemnitee, as determined in a final, non‑appealable judgment by a court of competent jurisdiction. This indemnification shall survive the payment and satisfaction of all Obligations and the termination of this Agreement for a period of five (5) years, and shall remain in force beyond the expiration of any applicable statute of limitations and payment or satisfaction in full of any single claim under this indemnification. This

indemnification shall be binding upon the successors and assigns of the Borrower and shall inure to the benefit of each Indemnitee and its successors and assigns.

(c)    To the extent that (i) the Loan Parties for any reason fail to indefeasibly pay any amount required under subsection (a) or (b) of this Section to be paid by any of them to the Administrative Agent (or any sub‑agent thereof), the L/C Issuer, the Swingline Lender or any Related Party (and without limiting its obligation to do so) or (ii) any liabilities, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever are imposed on, incurred by, or asserted against, Administrative Agent, the L/C Issuer, the Swingline Lender or a Related Party in any way relating to or arising out of this Agreement or any other Loan Document or any action taken or omitted to be taken by Administrative Agent, the L/C Issuer, the Swingline Lender or a Related Party in connection therewith, then, in each case, each Lender severally agrees to pay to the Administrative Agent (or any such sub‑agent), the L/C Issuer, the Swingline Lender or such Related Party, as the case may be, such Lender’s Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought based on each Lender’s share of the Total Credit Exposure at such time) of such unpaid amount (including any such unpaid amount in respect of a claim asserted by such Lender); provided that with respect to such unpaid amounts owed to the L/C Issuer or the Swingline Lender solely in its capacity as such, only the Lenders party to the Revolving Credit shall be required to pay such unpaid amounts, such payment to be made severally among them based on such Lenders’ pro rata share (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought based on each such Lender’s share of the Revolving Credit Exposure at such time); and provided, further, that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent (or any such sub‑agent), the L/C Issuer or the Swingline Lender in its capacity as such, or against any Related Party of any of the foregoing acting for the Administrative Agent (or any such sub‑agent), the L/C Issuer or the Swingline Lender in connection with such capacity. The Lenders’ obligations under this Section shall survive the termination of the Loan Documents and payment of the obligations hereunder.

Section 12.14.    Set‑off . In addition to any rights now or hereafter granted under the Loan Documents or applicable law and not by way of limitation of any such rights, if an Event of Default shall have occurred and be continuing, with the prior written consent of the Administrative Agent, each Lender, the L/C Issuer, and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held, and other obligations (in whatever currency) at any time owing, by such Lender, the L/C Issuer or any such Affiliate, to or for the credit or the account of the Borrower or any other Loan Party against any and all of the obligations of the Borrower or such Loan Party now or hereafter existing under this Agreement or any other Loan Document to such Lender or the L/C Issuer or

their respective Affiliates, irrespective of whether or not such Lender, the L/C Issuer or Affiliate shall have made any demand under this Agreement or any other Loan Document and although such obligations of the Borrower or such Loan Party may be contingent or unmatured or are owed to a branch, office or Affiliate of such Lender or the L/C Issuer different from the branch, office or Affiliate holding such deposit or obligated on such indebtedness; provided that in the event that any Defaulting Lender shall exercise any such right of setoff, (x) all amounts so set off shall be paid over immediately to the Administrative Agent for further application in accordance with the provisions of Section 1.14 and, pending such payment, shall be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of the Administrative Agent, the L/C Issuer, and the Lenders, and (y) the Defaulting Lender shall provide promptly to the Administrative Agent a statement describing in reasonable detail the Obligations owing to such Defaulting Lender as to which it exercised such right of setoff. The rights of each Lender, the L/C Issuer and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender, the L/C Issuer or their respective Affiliates may have. Each Lender and the L/C Issuer agrees to notify the Borrower and the Administrative Agent promptly after any such setoff and application; provided that the failure to give such notice shall not affect the validity of such setoff and application.

Section 12.15.    Severability of Provisions. Any provision of any Loan Document which is unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such unenforceability without invalidating the remaining provisions hereof or affecting the validity or enforceability of such provision in any other jurisdiction. All rights, remedies and powers provided in this Agreement and the other Loan Documents may be exercised only to the extent that the exercise thereof does not violate any applicable mandatory provisions of law, and all the provisions of this Agreement and other Loan Documents are intended to be subject to all applicable mandatory provisions of law which may be controlling and to be limited to the extent necessary so that they will not render this Agreement or the other Loan Documents invalid or unenforceable.

Section 12.16.    Excess Interest . Notwithstanding any provision to the contrary contained herein or in any other Loan Document, no such provision shall require the payment or permit the collection of any amount of interest in excess of the maximum amount of interest permitted by applicable law to be charged for the use or detention, or the forbearance in the collection, of all or any portion of the Loans or other obligations outstanding under this Agreement or any other Loan Document ( “Excess Interest” ). If any Excess Interest is provided for, or is adjudicated to be provided for, herein or in any other Loan Document, then in such event (a) the provisions of this Section shall govern and control, (b) neither the Borrower nor any Guarantor or endorser shall be obligated to pay any Excess Interest, (c) any Excess Interest that the Administrative Agent or any Lender may have received hereunder shall, at the option of the Administrative Agent, be (i) applied as a credit against the then outstanding principal amount of Obligations hereunder and accrued and unpaid

interest thereon (not to exceed the maximum amount permitted by applicable law), (ii) refunded to the Borrower, or (iii) any combination of the foregoing, (d) the interest rate payable hereunder or under any other Loan Document shall be automatically subject to reduction to the maximum lawful contract rate allowed under applicable usury laws (the “Maximum Rate” ), and this Agreement and the other Loan Documents shall be deemed to have been, and shall be, reformed and modified to reflect such reduction in the relevant interest rate, and (e) neither the Borrower nor any Guarantor or endorser shall have any action against the Administrative Agent or any Lender for any damages whatsoever arising out of the payment or collection of any Excess Interest. Notwithstanding the foregoing, if for any period of time interest on any of Borrower’s Obligations is calculated at the Maximum Rate rather than the applicable rate under this Agreement, and thereafter such applicable rate becomes less than the Maximum Rate, the rate of interest payable on the Borrower’s Obligations shall remain at the Maximum Rate until the Lenders have received the amount of interest which such Lenders would have received during such period on the Borrower’s Obligations had the rate of interest not been limited to the Maximum Rate during such period.

Section 12.17.    Construction . The parties acknowledge and agree that the Loan Documents shall not be construed more favorably in favor of any party hereto based upon which party drafted the same, it being acknowledged that all parties hereto contributed substantially to the negotiation of the Loan Documents. The provisions of this Agreement relating to Subsidiaries shall only apply during such times as the Borrower has one or more Subsidiaries.

Section 12.18.    Governing Law; Jurisdiction; Consent to Service of Process . (a) THIS AGREEMENT, THE NOTES AND THE OTHER LOAN DOCUMENTS (EXCEPT AS OTHERWISE SPECIFIED THEREIN), AND THE RIGHTS AND DUTIES OF THE PARTIES HERETO, SHALL BE CONSTRUED AND DETERMINED IN ACCORDANCE WITH THE LAWS OF THE STATE OF ILLINOIS WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES THAT WOULD REQUIRE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION.

(b)    Each party hereto hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the United States District Court for the Northern District of Illinois and of any Illinois State court sitting in the City of Chicago, and any appellate court from any thereof, in any action or proceeding arising out of or relating to any Loan Document, or for recognition or enforcement of any judgment, and each party hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such Illinois State court or, to the extent permitted by applicable Legal Requirements, in such federal court. Each party hereto hereby agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Legal Requirements. Nothing in this Agreement or

any other Loan Document or otherwise shall affect any right that the Administrative Agent, the L/C Issuer or any Lender may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document against the Borrower or any Guarantor or its respective properties in the courts of any jurisdiction.

(c)    The Borrower and each Guarantor hereby irrevocably and unconditionally waives, to the fullest extent permitted by applicable Legal Requirements, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any other Loan Document in any court referred to in Section 12.18(b). Each party hereto hereby irrevocably waives, to the fullest extent permitted by applicable Legal Requirements, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d)    Each party to this Agreement irrevocably consents to service of process in any action or proceeding arising out of or relating to any Loan Document, in the manner provided for notices (other than telecopy or e‑mail) in Section 12.8. Nothing in this Agreement or any other Loan Document will affect the right of any party to this Agreement to serve process in any other manner permitted by applicable Legal Requirements.

Section 12.19.    Waiver of Jury Trial . EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LEGAL REQUIREMENTS, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO ANY LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

Section 12.20.    USA Patriot Act . Each Lender and the L/C Issuer that is subject to the requirements of the USA Patriot Act (Title III of Pub. L. 107‑56 (signed into law October 26, 2001)) (the “Act” ) hereby notifies the Loan Parties that pursuant to the requirements of the Act, it is required to obtain, verify, and record information that identifies each Loan Party, which information includes the name and address of such Loan Party and other information that will allow such Lender or the L/C Issuer to identify such Loan Party in accordance with the Act.

Section 12.21.     Confidentiality . Each of the Administrative Agent, the Lenders, and the L/C Issuer severally agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors to the extent any such Person has a need to know such Information (it being understood that the Persons to whom such disclosure is made will first be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority (including any self‑regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any suit, action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (A) any assignee of or participant in, or any prospective assignee of or participant in, any of its rights or obligations under this Agreement or (B) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to Whitestone REIT, the Borrower or any Subsidiary and its obligations, (g) with the prior written consent of the Borrower, (h) to the extent such Information (A) becomes publicly available other than as a result of a breach of this Section or (B) becomes available to the Administrative Agent, any Lender or the L/C Issuer on a non‑confidential basis from a source other than Whitestone REIT, the Borrower or any Subsidiary or any of their directors, officers, employees or agents, including accountants, legal counsel and other advisors, (i) to rating agencies if requested or required by such agencies in connection with a rating relating to the Loans or the Commitments hereunder, or (j) to entities which compile and publish information about the syndicated loan market, provided that only basic information about the pricing and structure of the transaction evidenced hereby may be disclosed pursuant to this subsection (j). For purposes of this Section, “Information” means all information received from the Borrower or any of the Subsidiaries or from any other Person on behalf of Whitestone REIT, the Borrower or any Subsidiary relating to Whitestone REIT, the Borrower or any Subsidiary or any of their respective businesses, other than any such information that is available to the Administrative Agent, any Lender or the L/C Issuer on a non-confidential basis prior to disclosure by Whitestone REIT, the Borrower or any of its Subsidiaries or from any other Person on behalf of Whitestone REIT, the Borrower or any of the Subsidiaries.

Section 12.22.    Amendment and Restatement; No Novation . From and after the date of this Agreement, all references to the Prior Credit Agreement in any Loan Document or in any other instrument or document shall, unless otherwise explicitly stated therein, be deemed to refer to this Agreement. This Agreement shall become effective as of the date hereof, and supersede all provisions of the Prior Credit Agreement as of such date, upon the execution of this Agreement by each of the parties hereto and fulfillment of the conditions precedent contained in Section 7.2 hereof.

This Agreement shall constitute for all purposes an amendment and restatement of the Prior Credit Agreement and not a new agreement and all obligations outstanding under the Prior Credit Agreement shall, subject to Section 12.23 hereof, continue to be outstanding hereunder and shall not constitute a novation of the indebtedness or other obligations outstanding under the Prior Credit Agreement.

Section 12.23.    Equalization of Loans and Commitments. Upon the satisfaction of the conditions precedent set forth in Section 7.2 hereof, all loans outstanding under the Prior Credit Agreement shall remain outstanding as the initial Borrowing of Loans under this Agreement and, in connection therewith, the Borrower shall be deemed to have prepaid all outstanding Eurodollar Loans on the Closing Date and shall pay to each Lender who is currently a party to the Prior Credit Agreement any compensation due such Lender under Section 1.11 of the Prior Credit Agreement as a result thereof (to the extent invoiced prior to the Closing Date and if not waived under the Prior Credit Agreement by any Lender in writing delivered to the Administrative Agent prior to the Closing Date). On the Closing Date, the Lenders each agree to make such purchases and sales of interests in the outstanding Loans between themselves so that each Lender is then holding its relevant Percentage of outstanding Loans. Such purchases and sales shall be arranged through the Administrative Agent and each Lender hereby agrees to execute such further instruments and documents, if any, as the Administrative Agent may reasonably request in connection therewith.

Section 13.1.    The Guarantees . To induce the Lenders and the L/C Issuer to provide the credits described herein and in consideration of benefits expected to accrue to the Borrower by reason of the Commitments and for other good and valuable consideration, receipt of which is hereby acknowledged, Whitestone REIT and, subject to the terms of Section 4.3 hereof, each Material Subsidiary party hereto, (including any Material Subsidiary formed or acquired after the Closing Date executing an Additional Guarantor Supplement in the form attached hereto as Exhibit G or such other form acceptable to the Administrative Agent) hereby unconditionally and irrevocably guarantee jointly and severally to the Administrative Agent, the Lenders, the L/C Issuer and their Affiliates, the due and punctual payment of all present and future Obligations, Hedging Liability and Bank Product Obligations, including, but not limited to, the due and punctual payment of principal of and interest on the Loans, the Reimbursement Obligations and the due and punctual payment of all other obligations now or hereafter owed by the Borrower under the Loan Documents and the due and punctual payment of all Hedging Liability and Bank Product Obligations, in each case as and when the same shall become due and payable, whether at stated maturity, by acceleration, or otherwise, according to the terms hereof and thereof (including all interest, costs, fees, and charges after the entry of an order for relief against the Borrower or such other obligor in a case under the United States Bankruptcy Code or any similar proceeding, whether or not such interest, costs, fees

and charges would be an allowed claim against the Borrower or any such obligor in any such proceeding). In case of failure by the Borrower or other obligor punctually to pay any obligations guaranteed hereby, each Guarantor hereby unconditionally agrees to make such payment or to cause such payment to be made punctually as and when the same shall become due and payable, whether at stated maturity, by acceleration, or otherwise, and as if such payment were made by the Borrower or such obligor.

Section 13.2.    Guarantee Unconditional . The obligations of each Guarantor under this Section 13 shall be unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged, or otherwise affected by:

(a)    any extension, renewal, settlement, compromise, waiver, or release in respect of any obligation of the Borrower or other obligor or of any other guarantor under this Agreement or any other Loan Document or by operation of law or otherwise;

(b)    any modification or amendment of or supplement to this Agreement or any other Loan Document or any agreement relating to Hedging Liability or Bank Product Obligations;

(c)    any change in the corporate existence, structure, or ownership of, or any insolvency, bankruptcy, reorganization, or other similar proceeding affecting, the Borrower or other obligor, any other guarantor, or any of their respective assets, or any resulting release or discharge of any obligation of the Borrower or other obligor or of any other guarantor contained in any Loan Document;

(d)    the existence of any claim, set‑off, or other rights which the Borrower or other obligor or any other guarantor may have at any time against the Administrative Agent, any Lender, the L/C Issuer or any other Person, whether or not arising in connection herewith;

(e)    any failure to assert, or any assertion of, any claim or demand or any exercise of, or failure to exercise, any rights or remedies against the Borrower or other obligor, any other guarantor, or any other Person or Property;

(f)    any application of any sums by whomsoever paid or howsoever realized to any obligation of the Borrower or other obligor, regardless of what obligations of the Borrower or other obligor remain unpaid;

(g)    any invalidity or unenforceability relating to or against the Borrower or other obligor or any other guarantor for any reason of this Agreement or of any other Loan Document or any agreement relating to Hedging Liability or Bank Product Obligations or

any provision of applicable law or regulation purporting to prohibit the payment by the Borrower or other obligor or any other guarantor of the principal of or interest on any Loan or any Reimbursement Obligation or any other amount payable under the Loan Documents or any agreement relating to Hedging Liability or Bank Product Obligations; or

(h)    any other act or omission to act or delay of any kind by the Administrative Agent, any Lender, the L/C Issuer, or any other Person or any other circumstance whatsoever that might, but for the provisions of this paragraph, constitute a legal or equitable discharge of the obligations of any Guarantor under this Section 13.

Section 13.3.    Discharge Only upon Payment in Full; Reinstatement in Certain Circumstances . Except as otherwise set forth in Section 4.3 or Section 7.3 hereof, each Guarantor’s obligations under this Section 13 shall remain in full force and effect until the Commitments are terminated, all Letters of Credit have expired, and the principal of and interest on the Loans and all other amounts payable by the Borrower and the Guarantors under this Agreement and all other Loan Documents and, if then outstanding and unpaid, all Hedging Liability and Bank Product Obligations shall have been paid in full. If at any time any payment of the principal of or interest on any Loan or any Reimbursement Obligation or any other amount payable by the Borrower or other obligor or any Guarantor under the Loan Documents or any agreement relating to Hedging Liability or Bank Product Obligations is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy, or reorganization of the Borrower or other obligor or of any guarantor, or otherwise, each Guarantor’s obligations under this Section 13 with respect to such payment shall be reinstated at such time as though such payment had become due but had not been made at such time.

Section 13.4.    Subrogation . Each Guarantor agrees it will not exercise any rights which it may acquire by way of subrogation by any payment made hereunder, or otherwise, until all the obligations guaranteed hereby shall have been paid in full subsequent to the termination of all the Commitments and expiration of all Letters of Credit. If any amount shall be paid to a Guarantor on account of such subrogation rights at any time prior to the later of (x) the payment in full of the Obligations, Hedging Liability and Bank Product Obligations and all other amounts payable by the Borrower hereunder and the other Loan Documents and (y) the termination of the Commitments and expiration of all Letters of Credit, such amount shall be held in trust for the benefit of the Administrative Agent, the L/C Issuer and the Lenders (and their Affiliates) and shall forthwith be paid to the Administrative Agent for the benefit of the Lenders and the L/C Issuer (and their Affiliates) or be credited and applied upon the Obligations, Hedging Liability and Bank Product Obligations, whether matured or unmatured, in accordance with the terms of this Agreement.

Section 13.5.    Waivers . Each Guarantor irrevocably waives acceptance hereof, presentment, demand, protest, and any notice except as specifically provided for herein, as well as any requirement

that at any time any action be taken by the Administrative Agent, any Lender, the L/C Issuer or any other Person against the Borrower or other obligor, another guarantor, or any other Person.

Section 13.6.    Limit on Recovery . Notwithstanding any other provision hereof, the right of recovery against each Guarantor under this Section 13 shall not exceed $1.00 less than the lowest amount which would render such Guarantor’s obligations under this Section 13 void or voidable under applicable law, including, without limitation, fraudulent conveyance law.

Section 13.7.    Stay of Acceleration . If acceleration of the time for payment of any amount payable by the Borrower or other obligor under this Agreement or any other Loan Document, or any agreement relating to Hedging Liability or Bank Product Obligations, is stayed upon the insolvency, bankruptcy or reorganization of the Borrower or such obligor, all such amounts otherwise subject to acceleration under the terms of this Agreement or the other Loan Documents, or under any agreement relating to Hedging Liability or Bank Product Obligations, shall nonetheless be payable by the Guarantors hereunder forthwith on demand by the Administrative Agent made at the request of the Required Lenders.

Section 13.8.    Benefit to Guarantors . The Borrower and the Guarantors are engaged in related businesses and integrated to such an extent that the financial strength and flexibility of the Borrower has a direct impact on the success of each Guarantor. Each Guarantor will derive substantial direct and indirect benefit from the extensions of credit hereunder.

Section 13.9.    Guarantor Covenants. Each Guarantor shall take such action as the Borrower is required by this Agreement to cause such Guarantor to take, and shall refrain from taking such action as the Borrower is required by this Agreement to prohibit such Guarantor from taking.

Section 13.10.    Keepwell . Each Qualified ECP Guarantor hereby jointly and severally absolutely, unconditionally and irrevocably undertakes to provide such funds or other support as may be needed from time to time by each other Loan Party to honor all of its obligations under this Guaranty in respect of Swap Obligations (provided, however, that each Qualified ECP Guarantor shall only be liable under this Section for the maximum amount of such liability that can be hereby incurred without rendering its obligations under this Section, or otherwise under the Guaranty provided hereby, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount). The obligations of each Qualified ECP Guarantor under this Section shall remain in full force and effect until discharged in accordance with Section 13.3. Each Qualified ECP Guarantor intends that this Section constitute, and this Section shall be deemed to constitute, a “keepwell, support, or other agreement” for the benefit of each other Loan Party for all purposes of Section 1a(18)(A)(v)(II) of the Commodity Exchange Act.

Section 13.11.    Subordination     . Each Guarantor (each referred to herein as a “Subordinated Creditor” ) hereby subordinates the payment of all indebtedness, obligations, and liabilities of the Borrower or other Loan Party owing to such Subordinated Creditor, whether now existing or hereafter arising, to the indefeasible payment in full in cash of all Obligations, Hedging Liability, and Bank Product Obligations. During the existence of any Event of Default, subject to Section 13.4, any such indebtedness, obligation, or liability of the Borrower or other Loan Party owing to such Subordinated Creditor shall be enforced and performance received by such Subordinated Creditor as trustee for the benefit of the holders of the Obligations, Hedging Liability, and Bank Product Obligations and the proceeds thereof shall be paid over to the Administrative Agent for application to the Obligations, Hedging Liability, and Bank Product Obligations (whether or not then due), but without reducing or affecting in any manner the liability of such Guarantor under this Section 13.
