consent of the other. Notwithstanding the foregoing, the Buyer may assign its rights hereunder to any person that purchases Securities

the consent of the Company.

and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other person.

Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express

1.Remedies.
The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Buyer by vitiating
the intent and purpose of the transaction contemplated hereby. Accordingly, the Company acknowledges that the remedy at law for
a breach of its obligations under this Agreement will be inadequate and agrees, in the event of a breach or threatened breach by
the Company of the provisions of this Agreement, that the Buyer shall be entitled, in addition to all other available remedies
at law or in equity, and in addition to the penalties assessable herein, to an injunction or injunctions restraining, preventing
or curing any breach of this Agreement and to enforce specifically the terms and provisions hereof, without the necessity of showing
economic loss and without any bond or other security being required.
