OTHERWISE ARISING OUT OF OR RELATING TO THIS IP AGREEMENT OR THE ACTION OF ANY OF THE PARTIES THERETO IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT THEREOF. Section 6.7 Severability. If any term or provision of this IP Agreement is determined to be invalid, illegal or unenforceable, the remaining terms and provisions of this IP Agreement remain in full force, if the essential terms and conditions of this IP Agreement for each party remain valid, binding and enforceable. Upon such determination that any term or other provision is invalid, illegal or unenforceable, the parties hereto will negotiate in good faith to modify this IP Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible. Section 6.8 Entire Agreement; Conflicting Provisions. This IP Agreement, together with the other Transaction Agreements and any side letters executed by the parties in connection therewith, and all of the exhibits and schedules appended hereto and thereto, constitute the final, complete and exclusive statement of the parties' agreement on the matters contained herein and therein. All prior and contemporaneous negotiations and agreements between the parties on the matters contained in this IP Agreement and the other Transaction Agreements are superseded by this IP Agreement and the other Transaction Agreements, including, but subject to Section 5.5(b) of the Acquisition Agreement, the NDA. In the event of any conflict between any specific provision of this IP Agreement (including Article V) and the provisions of the Acquisition Agreement with respect to the subject matter hereof, the provisions of this IP Agreement will control. Section 6.9 Counterparts. The parties may execute this IP Agreement in multiple counterparts, each of which constitutes an original as against the party that signed it, and all of which together constitute one agreement. This IP Agreement is effective upon delivery of one executed counterpart from each party to the other party. The signatures of all parties need not appear on the same counterpart. The delivery of signed counterparts by facsimile or email transmission which includes a copy of the sending party's signature(s) is as effective as signing and delivering the counterpart in person. Section 6.10 Amendment. The parties may amend this IP Agreement only by a written agreement signed by the parties and that identifies itself as an amendment to this IP Agreement. Section 6.11 Waiver. The parties may waive a provision of this IP Agreement only by a writing signed by the party against whom enforcement of the waiver is sought. A party is not prevented from enforcing any right, remedy or condition in the party's favor because of any failure or delay in exercising any right or remedy or in requiring satisfaction of any condition, except to the extent that the party specifically waives the same in writing. A written waiver given for one matter or occasion is effective only in that instance and only for the purpose stated. A waiver once given is not to be construed as a waiver for any other matter or occasion. Any enumeration of a party's rights and remedies in this Agreement is not intended to be exclusive, and a party's rights and remedies are intended to be cumulative to the extent permitted by Law and include any rights and remedies authorized in Law or in equity. Section 6.12 Notices. Each party giving any notice required or permitted under this IP Agreement will give the notice in writing, and shall be deemed to have been duly given: (i) when received if delivered personally; (ii) when transmitted if sent by facsimile (with transmission confirmed); (iii) the day after it is sent if sent by commercial overnight courier; (iv) upon receipt if sent by certified or registered mail (return receipt requested); or (v) when transmitted if sent by email (with receipt confirmed by recipient). Notice to a party is effective for purposes of this Agreement only if given as provided in this Section 6.12 at the address of which the sending party has been notified in accordance with this Section 6.12.
