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.
