f)       Severability.
If any provision of this Note is invalid, illegal or unenforceable, the balance of this Note shall remain in effect, and if any
provision is inapplicable to any Person or circumstance, it shall nevertheless remain applicable to all other Persons and circumstances.
If it shall be found that any interest or other amount deemed interest due hereunder violates the applicable law governing usury,
the applicable rate of interest due hereunder shall automatically be lowered to equal the maximum rate of interest permitted under
applicable law. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead,
or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would
prohibit or forgive the Company from paying all or any portion of the principal of or interest on this Note as contemplated herein,
wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Note, and
the Company (to the extent it may lawfully do so) hereby expressly waives all benefits or advantage of any such law, and covenants
that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Holder,
but will suffer and permit the execution of every such power as though no such law has been enacted.


 


g)      Remedies,
Characterizations, Other Obligations, Breaches and Injunctive Relief. The remedies provided in this Note shall be cumulative
and in addition to all other remedies available under this Note and any of the other Transaction Documents at law or in equity
(including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the Holder’s
right to pursue actual and consequential damages for any failure by the Company to comply with the terms of this Note.  The
Company covenants to the Holder that there shall be no characterization concerning this instrument other than as expressly provided
herein. Amounts set forth or provided for herein with respect to payments and the like (and the computation thereof) shall be
the amounts to be received by the Holder and shall not, except as expressly provided herein, be subject to any other obligation
of the Company (or the performance thereof). The Company acknowledges that a breach by it of its obligations hereunder will cause
irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees
that, in the event of any such breach or threatened breach, the Holder shall be entitled, in addition to all other available remedies,
to an injunction restraining any such breach or any such threatened breach, without the necessity of showing economic loss and
without any bond or other security being required. The Company shall provide all information and documentation to the Holder that
is requested by the Holder to enable the Holder to confirm the Company’s compliance with the terms and conditions of this
Note.


 


h)      Next

shall be made on the next succeeding Business Day.
