reproduce, prepare, distribute, publicly display, publicly perform, sublicense,
copy, create derivative works of, and make modifications to the Model, for any
purpose, subject to the restrictions set forth in Attachment A; provided however,
that entities with annual revenues of at least $10,000,000 (the “Commercial

Any commercial use of the Model or Derivatives of the Model by the Commercial

Such material breach will be subject, in addition to any license fees owed to
Licensor for the period such Commercial Entity used the Model (as will be determined
by Licensor), to liquidated damages, 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.
