The total aggregate commitments under the Revolving Credit Agreement remain at $3.9 billion. The Existing Revolving Credit Agreement, as amended by the Fourteenth Amendment, is referred to herein as the “Revolving Credit Agreement,” and the credit facility thereunder is referred to herein as the “Revolving Credit Facility.” The Revolving Credit Agreement provides for a $3.9 billion multi-currency revolving facility, with sub-limits for non-dollar borrowings and letters of credit and with a swingline facility available on a same-day basis. The Revolving Credit Agreement includes an option for the Company to propose an increase in the aggregate amount available for borrowing by up to $1.25 billion, subject to the consent of the lenders funding the increase and certain other conditions. Amounts borrowed under the Revolving Credit Agreement may be prepaid at any time without premium or penalty, and borrowings thereunder bear interest at term SOFR or a base rate, at the Company’s option, plus an applicable ratings-based margin ranging from 0.750% (or 0.875% with respect to non-consenting lenders) to 1.375% (or 1.500% with respect to non-consenting lenders) on term SOFR loans (with non-consenting lenders subject to a credit spread adjustment of 10 basis points), and from 0.000% to 0.375% (or 0.500% with respect to non-consenting lenders) for base rate loans, based on a ratings-based pricing grid. The amounts available under the Revolving Credit Agreement are available to the Company to use for working capital and general corporate purposes including, but not limited to, acting as a backstop to the amounts issued under the Company’s commercial paper program. The MarketAxess Revolving Commitments are available to (i) finance a portion of the consideration for the MarketAxess Acquisition, (ii) refinance all or a portion of the existing indebtedness of MarketAxess and its subsidiaries and/or (iii) pay fees, costs, commissions and expenses in connection with the MarketAxess Acquisition and related transactions; provided that following the expiration of the MarketAxess certain funds period described in the Revolving Credit Agreement, the Company may elect to have such MarketAxess Revolving Commitments become available for working capital and general corporate purposes as described in the Revolving Credit Agreement. The Revolving Credit Agreement contains customary representations and warranties, covenants and events of default, including (i) a leverage ratio maintenance covenant, (ii) limitations on liens on the assets of the Company or its subsidiaries, (iii) limitations on indebtedness of the Company’s subsidiaries, (iv) limitations on the sale of all or substantially all of the assets of the Company and its subsidiaries, (v) limitations on fundamental changes and (vi) other matters.

The proceeds of the loans to be extended under the Term Loan Facility are expected to be used (i) to (A) finance a portion of the consideration for the MarketAxess Acquisition, (B) refinance all or a portion of the existing indebtedness of MarketAxess and its subsidiaries and/or (C) pay fees, costs, commissions and expenses in connection with the MarketAxess Acquisition and related transactions and (ii) to provide for working capital and other general corporate purposes. The Term Loan Facility will have no required amortization and will mature on the date that is 24 months after the funding date thereunder. Each loan under the Term Loan Facility will, at the Company’s option, bear interest on the principal amount outstanding at either (a) term SOFR plus an applicable margin rate or (b) a “base rate” plus an applicable margin rate. The applicable margin rate ranges from 0.625% to 1.250% on term SOFR loans and from 0.000% to 0.250% for base rate loans, based on a ratings-based pricing grid. The Company will have the right to prepay the outstanding loans under the Term Loan Facility, in whole or in part, without premium or penalty.
