The loans under the Credit Agreements are repayable in full on the Maturity Date, subject to mandatory prepayment provisions in the event of certain events including asset sales, incurrence of indebtedness, issuances of equity and receipt of casualty insurance proceeds. The terms of our Credit Agreements place restrictions on, among other things, and subject to certain exceptions, our ability to make certain restricted payments (including payments of dividends), make certain types of investments and acquisitions, issue redeemable securities, incur additional indebtedness, incur liens on our assets, enter into agreements with a negative pledge, make certain intercompany transfers, merge, consolidate, or sell our assets or the equity interests in our subsidiaries, amend our organizational documents or material contracts, enter into certain transactions with affiliates, or enter into derivatives contracts. Additionally, if we receive net cash proceeds from certain capital events (including equity issuances), we are required to prepay loans under our Credit Agreements. In addition, the Credit Agreements contain cross-default provisions that trigger an event of default if we fail to make certain payments or otherwise fail to comply with our obligations with respect to certain of our other indebtedness, including obligations under the FDP Loan Agreement.
