Also pursuant to the February 2016 amendment to the Credit Agreement, | | (a) | The minimum permitted Consolidated Interest Coverage Ratio was revised as follows: |
| | | | | Four Fiscal Quarters Ending | Minimum Consolidated Interest Coverage Ratio | | | | December 31, 2016 through and including March 31, 2017 | 2.75 |
| to 1.00 | June 30, 2017 and each fiscal quarter thereafter | 3.00 |
| to 1.00 |
| | (b) | The maximum permitted Consolidated Leverage Ratio was revised as follows: |
| | | | | Four Fiscal Quarters Ending | Maximum Consolidated Leverage Ratio | | | | December 31, 2016 | 5.00 |
| to 1.00 | March 31, 2017 | 4.75 |
| to 1.00 | June 30, 2017 | 4.25 |

| to 1.00 | December 31, 2017 and each fiscal quarter thereafter | 3.50 |
| to 1.00 |
| | (c) | A financial covenant was established requiring us to maintain a minimum cash balance if our Consolidated Leverage Ratio is 3.50x or greater, as described below. This minimum cash balance is not required to be maintained in any particular bank account or to be segregated from other cash balances in bank accounts that we use in our ordinary course of business. Because the use of this cash is not legally restricted notwithstanding this maintenance covenant, we present it as cash and cash equivalents on our balance sheet. As of December 31, 2016, we needed to maintain an aggregate cash balance of at least $150 million in order to comply with this covenant. |
| | | | Consolidated Leverage Ratio | Minimum Cash Balance | | | Greater than or equal to 4.50x | $150,000,000.00 | Greater than or equal to 4.00x but less than 4.50x | 100,000,000.00 | Greater than or equal to 3.50x but less than 4.00x | 50,000,000.00 | Less than 3.50x | 0.00 |
