Whenever the context may require, any pronoun includes the corresponding masculine, feminine and neuter forms. Any term defined by reference to any agreement, instrument or document has the meaning assigned to it whether or not such agreement, instrument or document is in effect. Any reference to any federal, state, local or foreign statute or law shall be deemed also to refer to all rules and regulations promulgated thereunder, unless the context requires otherwise. The words "include", "includes" and "including" are deemed to be followed by the phrase "without limitation".

Unless the context otherwise requires, references herein to any Person include its successors and assigns.

(h) Specific Performance The parties agree that irreparable harm would occur in the event that any of the agreements and provisions of this Agreement were not performed fully by the parties in accordance with their specific terms or conditions or were otherwise breached, and that money damages are an inadequate remedy for breach of this Agreement because of the difficulty of ascertaining and quantifying the amount of damage that would be suffered by the parties in the event that this Agreement were not performed in accordance with its terms or conditions or were otherwise breached. It is accordingly hereby agreed that the parties shall be entitled to an injunction or injunctions to restrain, enjoin and prevent breaches of this Agreement by the other party and to enforce specifically such terms and conditions of this Agreement, such remedy being in addition to and not in lieu of any other rights and remedies to which the other Party is entitled to at law or in equity.

(i) Governing Law This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware.

(i) Construction. The parties have participated jointly in the negotiation and drafting of this Agreement.
