which will be paid to Licensor immediately upon demand, in an |
|
|
amount equal to double the amount that would otherwise have been |
|
|
paid by you for the relevant period of time. Such amount reflects |
|
|
a reasonable estimation of the losses and administrative costs |
|
|
incurred due to such breach. You agree and understand that this |
|
|
remedy does not limit the Licensor's right to pursue other remedies |
|

available at law or equity. |
