Ownership Limitation; Commitment Amount. At the request of [[Organization B:Organization]], [[Organization A:Organization]] will inform [[Organization B:Organization]] in writing (which may be by e-mail) of the number of Common Shares [[Organization A:Organization]] currently beneficially owns. At the request of [[Organization A:Organization]], [[Organization B:Organization]] shall promptly confirm in writing (which may be by e-mail) to [[Organization A:Organization]] the number of Common Shares then outstanding. Notwithstanding anything to the contrary contained in this Agreement, [[Organization A:Organization]] shall not be obligated to purchase or acquire, and shall not purchase or acquire, any Shares under this Agreement which, when aggregated with all other Common Shares beneficially owned by [[Organization A:Organization]] and its affiliates (as calculated pursuant to Section 13(d) of the Exchange Act and Rule 13d-3 promulgated thereunder), would result in the beneficial ownership by [[Organization A:Organization]] and its affiliates (on an aggregated basis) to exceed 4.99% of the then outstanding voting power or number of Common Shares (the “Ownership Limitation”). In connection with each Purchase Notice, any portion of Shares requested to be purchased in such Purchase Notice that would # cause [[Organization A:Organization]] to exceed the Ownership Limitation or # cause the aggregate number of Shares issued and sold to [[Organization A:Organization]] hereunder to exceed the Commitment Amount shall automatically be withdrawn with no further action required by [[Organization B:Organization]] or [[Organization A:Organization]], and such Purchase Notice shall be deemed automatically modified to reduce the number of Shares requested to be purchased by an amount equal to such withdrawn portion; provided that in the event of any such automatic withdrawal and automatic modification, [[Organization A:Organization]] will promptly notify [[Organization B:Organization]] of such event, including the number of Shares affected by such withdrawal or modification.

Reductions in Aggregate Commitment. The Borrowers may permanently reduce the Aggregate Commitment in whole, or in a minimum aggregate amount of $25,000,000 and in integral multiples of $1,000,000 if in excess thereof (or the Dollar Equivalent thereof, if denominated in an Agreed Currency other than Dollars), ratably among [[Organization B:Organization]], upon at least three Business Days’ written notice to the Agent, which notice shall specify the amount of any such reduction, provided, however, that the amount of the Aggregate Commitment may not be reduced below the aggregate principal Dollar Equivalent of the outstanding Advances. All accrued Commitment Fees shall be payable on the effective date of any termination of the obligations of [[Organization B:Organization]] to make Loans hereunder and on the final date upon which all Loans are repaid hereunder. The Aggregate Commitment once reduced as provided in this [Section 2.6(b)] may only be reinstated as specifically provided in [Section 2.6(c)] below. If # any Lender notifies the Company in accordance with [Section 3.5(d) or (ii)])] a Borrower reasonably determines that it is or will be required to make any additional payment to any Lender under [Sections 3.1 or 3.2], then the Company may, at any time thereafter (provided that no Default or Unmatured Default then exists and no satisfactory solution has been reached pursuant to [Section 3.6]) and by not less than five Business Days’ prior written notice to the Agent, cancel such Lender’s Commitment, whereupon such Lender shall cease to be obliged to make further Loans hereunder and its Commitment shall be reduced to zero. Upon termination of such Lender’s Commitment, each applicable Borrower shall, subject to the last sentence of this [Section 2.6(b)], pay all outstanding Obligations owing to such Lender. Any notice of cancellation given pursuant to this [Section 2.6(b)] shall be irrevocable and shall specify the date upon which such cancellation is to take effect. Notwithstanding any such cancellation, the obligations of the Company under Sections 3.1, 3.2 and 10.66] shall survive any such cancellation and be enforceable by such Lender. In any case described in clauses (b)(i) or (b)(ii) above in which the Company has the right to cancel a Lender’s Commitment, the Company may, in connection with such cancellation, arrange for a sale (at par) of such Commitment and all outstanding Loans held by such Lender pursuant to the terms of Section 13.3 and such Lender will promptly enter into any such sale arranged by the Company.

Increase in Aggregate Commitment. (i) The Company may at any time propose that the Aggregate Commitment be increased (the amount of such increase being a “Commitment Increase”), effective as at a date prior to the Termination Date and at least 15 days after the Company proposes any such increase to the Agent in writing (an “Increase Date”) as to which agreement is to be reached by an earlier date specified in such notice (a “Commitment Date”); provided, however, that # the Company may not propose more than two Commitment Increases in any calendar year, # the Company may not propose more than five Commitment Increases pursuant to this Agreement, # the minimum proposed Commitment Increase per notice shall be $10,000,000, # in no event shall the Aggregate Commitment hereunder at any time exceed $4,500,000,000, and # no Default or Unmatured Default shall have occurred and be continuing on such Increase Date. The Agent shall notify [[Organization B:Organization]] thereof promptly upon its receipt of any such notice. The Agent agrees that it will cooperate with the Company in discussions with [[Organization B:Organization]] and other lending institutions with a view to arranging the proposed Commitment Increase through the increase of the Commitments of one or more of [[Organization B:Organization]] (each such Lender that is willing to increase its Commitment hereunder being an “Increasing Lender”) and/or through Commitments provided by one or more Assuming [[Organization B:Organization]]; provided, however, that it shall be in each Lender’s sole discretion whether to increase its Commitment hereunder in connection with the proposed Commitment Increase; and provided further that the minimum Commitment of each Assuming Lender that becomes a party to this Agreement pursuant to this [Section 2.6(c)] shall be at least equal to $10,000,000. If agreement is reached on or prior to the applicable Commitment Date with any Increasing [[Organization B:Organization]] and Assuming [[Organization B:Organization]] as to a Commitment Increase (which may be less than but not greater than specified in the applicable notice from the Company), such agreement to be evidenced by a notice in reasonable detail from the Company to the Agent on or prior to the applicable Commitment Date, such Assuming [[Organization B:Organization]], if any, shall become [[Organization B:Organization]] hereunder as of the applicable Increase Date and the Commitments of such Increasing [[Organization B:Organization]] and such Assuming [[Organization B:Organization]] shall become or be, as the case may be, as of the Increase Date, the amounts specified in such notice; provided that:

Revolving Credit Commitment Fee. The Borrower shall pay to the Administrative Agent for the ratable account of the Lenders in accordance with their Percentages a commitment fee at the rate per annum equal to the Applicable Margin (computed on the basis of a year of 360 days and the actual number of days elapsed) times the daily amount by which the aggregate Revolving Credit Commitments exceeds the principal amount of Revolving Loans and L/C Obligations then outstanding. Such commitment fee shall be payable quarterly in arrears on the last day of each March, June, September, and December in each year (commencing on the first such date occurring after the Closing Date) and on the Revolving Credit Termination Date, unless the Revolving Credit Commitments are terminated in whole on an earlier date, in which event the commitment fee for the period to the date of such termination in whole shall be paid on the date of such termination. Swing Loans shall not constitute usage of the Revolving Credit Commitment for purposes of calculating the Revolving Credit Commitment Fee.

New Revolving Commitment Lenders. Following any Extension Request made by the ​ in accordance with this Section 2.17, if the Revolving Credit Lenders shall have declined to agree during the period specified in [Section 2.17(b)] above to provide Extended Revolving Credit Commitments in an aggregate principal amount equal to the amount requested by the ​ in such Extension Request, the ​ may request that banks, financial institutions or other institutional lenders or investors other than the Revolving Credit Lenders or Extending Revolving Credit Lenders (the “New Revolving Commitment Lenders”), which New Revolving Commitment Lenders may elect to provide an Extended Revolving Credit Commitment hereunder (the “New Revolving Credit Commitment”); provided that such Extended Revolving Credit Commitments of such New Revolving Commitment Lenders # shall be in an aggregate principal amount for all such New Revolving Commitment Lenders not to exceed the aggregate principal amount of Extended Revolving Credit Commitments so declined to be provided by the existing Revolving Credit Lenders and # shall be on identical terms to the terms applicable to the terms specified in the applicable Extension Request (and any Extended Revolving Credit Commitments provided by existing Revolving Credit Lenders in respect thereof); provided further that, as a condition to the effectiveness of any Extended Revolving Credit Commitment of any New Revolving Commitment Lender, the [[Administrative Agent:Organization]], each Issuer and the Swing Loan Lender shall have consented (such consent not to be unreasonably withheld or delayed) to each New Revolving Commitment Lender if such consent would be required under [Section 12.2(b)(iii)] for an assignment of Revolving Credit Commitments to such Person. Notwithstanding anything herein to the contrary, any Extended Revolving Credit Commitment provided by New Revolving Commitment Lenders shall be pro rata to each New Revolving Commitment Lender. Upon effectiveness of the Extension Amendment to which each such New Revolving Commitment Lender is a party, # the Revolving Credit Commitments of all existing Revolving Credit Lenders of each Class specified in the Extension Amendment in accordance with this Section 2.17 will be permanently reduced pro rata by an aggregate amount equal to the aggregate principal amount of the Extended Revolving Credit Commitments of such New Revolving Commitment Lenders and # the Revolving Credit Commitment of each such New Revolving Commitment Lender will become effective. The Extended Revolving Credit Commitments of New Revolving Commitment Lenders will be incorporated as Revolving Credit Commitments hereunder in the same manner in which Extended Revolving Credit Commitments of existing Revolving Credit Lenders are incorporated hereunder pursuant to this Section 2.17, and for the avoidance of doubt, all Borrowings and repayments of Revolving Loans from and after the effectiveness of such Extension Amendment shall be made pro rata across all Classes of Revolving Credit Commitments including such New Revolving Commitment Lenders (based on the outstanding principal amounts of the respective Classes of Revolving Credit Commitments) except for # payments of interest and fees at different rates for each Class of Revolving Credit Commitments (and related Outstanding Amounts) and # repayments required on the Revolving Credit Termination Date for any particular Class of Revolving Credit Commitments. Upon the effectiveness of each New Revolving Credit Commitment pursuant to this [Section 2.17(c), (a)])] each Revolving Credit Lender of all applicable existing Classes of Revolving Credit Commitments immediately prior to such effectiveness will automatically and without further act be deemed to have assigned to each New Revolving Commitment Lender, and each such New Revolving Commitment Lender will automatically and without further act be deemed to have assumed, a portion of such Revolving Credit Lender’s participations hereunder in outstanding Letters of Credit and Swing Loans such that, after giving effect to each such deemed assignment and assumption of participations, subject to Section 2.16, the percentage of the outstanding # participations hereunder in Letters of Credit and # participations hereunder in Swing Loans held by each Revolving Credit Lender of each Class of Revolving Credit Commitments (including each such New Revolving Commitment Lender) will equal the percentage of the aggregate Revolving Credit Commitments of all Classes of Revolving Credit Lenders represented by such Revolving Credit Lender’s Revolving Credit Commitment and # if, on the date of such effectiveness, there are any Revolving Loans outstanding, such Revolving Loans shall on or prior to the effectiveness of such New Revolving Credit Commitment be prepaid from the proceeds of Revolving Loans made hereunder under the New Revolving Credit Commitments, which prepayment shall be accompanied by accrued interest on the Revolving Loans being prepaid and any costs incurred by any Revolving Credit Lender in accordance with Section 3.5. The [[Administrative Agent:Organization]] and the Lenders hereby agree that the minimum borrowing, pro rata borrowing and pro rata payment requirements contained elsewhere in this Agreement shall not apply to the transactions effected pursuant to the immediately preceding sentence.

“Commitment” means a Domestic Commitment, a Canadian Commitment, a U.K. Commitment and/or a PR Commitment, as the context may require.

Application of Commitment Reductions; Payment of Fees. The Administrative Agent will promptly notify the Appropriate ​ of any termination or reduction of unused portions of the Letter of Credit Sublimit or the Swing Line Sublimit or the unused Commitments of any Class under this ‎Section 2.06.

All commitment fees accrued until the effective date of any termination of the Aggregate Commitments shall be paid on the effective date of such termination.

Voluntary Reduction of Aggregate Revolving Loan Commitment. The Company (on behalf of itself and the Subsidiary Borrower) may permanently reduce the Aggregate Revolving Loan Commitment in whole, or in part ratably among the Revolving Loan Lenders of such Class, in an aggregate minimum amount of $5,000,000 with respect thereto and integral multiples of $2,500,000 in excess of that amount with respect thereto (unless the Revolving Loan Commitments of a Class are reduced in whole), upon at least three (3) Business Days’ prior written notice to the Administrative Agent, which notice shall specify the amount of any such reduction; provided, however, that the amount of the total Revolving Loan Commitments of any Class may not be reduced below the Dollar Amount of the Revolving Credit Obligations of such Class. All accrued commitment fees in respect of such Class shall be payable on the effective date of any termination of the obligations of any Revolving Loan Lenders of such Class to make Revolving Loans of such Class hereunder.

Mandatory Prepayments upon Commitment Terminations and Reductions. If, after giving effect to any termination or reduction of the Aggregate Commitments pursuant to Section 2.07(a) or (b), the Total Credit Exposure exceeds the Aggregate Commitments (as reduced), then # the Borrower shall prepay the Revolving Loans and/or Swingline Loans on the date of such termination or reduction in an aggregate principal amount equal to such excess, and # if any excess remains after prepaying all of the Revolving Loans and Swingline Loans as a result of LC Exposure, the Borrower shall cash collateralize such remaining excess as provided in Section 2.04(j). The Borrower shall be obligated to make such prepayment and/or deposit of such cash collateral on the date of the effectiveness of such termination or reduction.
