“(a) Request for Increase. Provided no Default has occurred and is continuing, upon notice to the Administrative Agent (which shall promptly notify the Lenders), the Borrower may from time to time request an increase in the Total Revolving Commitments; provided that (i) any such request for an increase shall be in a minimum amount of $15,000,000, (ii) the Borrower may make a maximum of three such requests during the Revolving Commitment Period, and (iii) after giving effect to such increase in the Total Revolving Commitments, the Total Revolving Commitments do not exceed $1,000,000,000. At the time of sending such notice, the Borrower may request all or part of such increase from the Lenders and, if it does so, shall specify (in consultation with the Administrative Agent) the time period within which each Lender who desires to commit to such increase is requested to respond.

“(b) Lender Elections to Increase. If Borrower so requests, each Lender may notify the Administrative Agent within such time period whether or not it agrees to increase its Revolving Commitment (which agreement may be given or withheld at such Lender’s sole and absolute discretion) and, if so, whether by an amount equal to, greater than, or less than its Revolving Percentage of such requested increase. Any Lender not responding within such time period shall be deemed to have declined to increase its Revolving Commitment.

“(c) Notification by Administrative Agent; Additional Lenders. The Administrative Agent shall notify the Borrower and each Lender of the Lenders’ responses to each request made hereunder. To achieve the full amount of a requested increase and subject to the approval of the Administrative Agent, the Swing Line Lender and each Issuing Lender (which approvals shall not be unreasonably withheld), the Borrower may also invite additional Persons who qualify as Eligible Assignees to become Lenders pursuant to a joinder agreement in form and substance satisfactory to the Administrative Agent and its counsel. It shall not be a condition to obtaining an increase in the Total Revolving Commitments that the full amount of such increase requested by the Borrower be approved by the Lenders or any additional Eligible Assignees. If less than the full amount of the increase requested by the Borrower is approved by the Lenders and any additional Eligible Assignee, the Borrower may, at its option, accept the amount of the increase so approved, or the Borrower may withdraw its request for all or a portion of such increase, in which case the Borrower shall be deemed not to have made a request for all or a portion of such increase, as applicable.

“(d) Effective Date and Allocations. If the Total Revolving Commitments are increased in accordance with this Section 2.14, the Administrative Agent and the Borrower shall determine the effective date (the “Increase Effective Date”) and the final allocation of such increase. The Administrative Agent shall promptly notify the Borrower and the Lenders of the final amount and allocation of such increase and the Increase Effective Date.

4

“(e) Conditions to Effectiveness of Increase. As a condition precedent to such increase, the Borrower shall deliver to the Administrative Agent a certificate of each Loan Party dated as of the Increase Effective Date (in sufficient copies for each Lender) signed by a Responsible Officer of such Loan Party (i) certifying and attaching the resolutions adopted by such Loan Party approving or consenting to such increase, and (ii) in the case of the Borrower, certifying that, before and after giving effect to such increase, (A) the representations and warranties contained in Article 4 and the other Loan Documents are true and correct on and as of the Increase Effective Date and (B) no Default exists. Administrative Agent shall notify the new or increasing Lenders of the amount of Loans of each Type and the applicable Interest Period thereof, and each such new or increasing Lender shall make Revolving Loans which are sufficient to make its outstanding Revolving Loans of each Type and of each Interest Period equal to such Lender’s Revolving Percentage of the Revolving Loans of such Type and such Interest Period. The Borrower shall pay to such new or increasing Lenders on the Increase Effective Date any costs reasonably determined by such Lender to have been incurred in respect of Eurodollar Loans related to such increase which are funded other than on the first day of the Interest Period relating thereto.

“(f) Conflicting Provisions. This Section shall supersede any provisions in Section 3.8 or Section 10.1 to the contrary.”
