Debt instrument covenant description | While the 2025 Secured Term Loan is outstanding, MacroStrategy is required to maintain a Loan to collateral value ratio (“LTV Ratio”) of 50% or less, which would amount to at least $410.0 million worth of bitcoin being required to be held in such account assuming the full $205.0 million of 2025 Secured Term Loan principal remains outstanding. If the price of bitcoin drops such that the LTV Ratio exceeds 50%, MacroStrategy is required to either deposit additional bitcoin in the Bitcoin Collateral Account or prepay a portion of the 2025 Secured Term Loan such that the LTV Ratio is reduced to 25% or less (or 35% or less, provided that in such case the interest rate on the 2025 Secured Term Loan will be increased by 25 basis points until such time as the LTV Ratio is reduced to 25% or less). If at any time the LTV Ratio is less than 25% as a result of excess collateral in the Bitcoin Collateral Account, MacroStrategy is entitled to a return of such excess collateral so long as the LTV Ratio would not exceed 25% after giving effect to such return |  |  |  |  |
