The Parties hereby waive any challenge to the jurisdiction or venue of the Court over these matters.

6.6 Sophisticated Parties Represented By Counsel. Each Party warrants and represents that (i) it is a sophisticated party represented at all relevant times during the negotiation and execution of this Agreement by counsel of its choice, and that it has executed this Agreement with the consent and on the advice of such independent legal counsel, (ii) it and its counsel have determined through independent investigation and robust, arm’s-length negotiation that the terms of this Agreement shall exclusively embody and govern the subject matter of this Agreement, (iii) it investigated the facts pertinent to this Agreement as it deemed necessary, (iv) no other Person or Party, nor any agent or attorney of a Party, made any promise, representation or warranty whatsoever, express or implied, not contained in this Agreement concerning the subject matter of this Agreement to induce it to execute this Agreement, (v) it has not executed this Agreement in reliance on any promise, representation or warranty whatsoever, express or implied, not contained in this Agreement concerning the subject matter of this Agreement, and (vi) it has not executed this Agreement in reliance on any promise, representation or warranty not contained herein.

The Parties hereby agree that (i) this is an enforceable agreement; (ii) this Agreement constitutes the entire and only understanding of each of them with respect to the subject matter of the Agreement, and merges, supersedes and cancels all previous agreements and understandings, whether oral or written, with respect to the subject matter of the Agreement; (iii) no oral explanation or oral information by any Party hereto shall alter the meaning or interpretation of this Agreement; (iv) the terms and conditions of this Agreement may be altered, modified, changed or amended only by a written agreement that identifies itself as an amendment to this Agreement and is executed by duly authorized representatives of each of them; (v) the language of this Agreement has been approved by counsel for each of them, and shall be construed as a whole according to its fair meaning; and (vi) none of them (nor their respective counsel) shall be deemed to be the draftsman of this Agreement in any action which may hereafter arise with respect to the Agreement.

6.11 Modification; Waiver . No modification or amendment to this Agreement, nor any waiver of any rights, will be effective unless assented to in writing by the Party to be charged, and the waiver of any breach or default will not constitute a waiver of any other right hereunder or any subsequent breach or default.

6.12 Construction; Language . Any rule of construction to the effect that ambiguities are to be resolved against the drafting Party will not be applied in the construction or interpretation of this Agreement. As used in this Agreement, the words “include” and “including” and variations thereof, will not be deemed to be terms of limitation, but rather will be deemed to be followed by the words “without limitation.” The terms “will” and “shall” are used synonymously. The headings in this Agreement will not be referred to in connection with the construction or interpretation of this Agreement. This Agreement is in the English language only, which language shall be controlling in all respects, and all notices under this Agreement shall be in the English language.

This Agreement may be executed in counterparts or duplicate originals, all of which shall be regarded as one and the same instrument, and which shall be the official and governing version in the interpretation of this Agreement. This Agreement may be executed by facsimile signatures or other electronic means and such signatures shall be deemed to bind each Party as if they were original signatures.
