The Company shall be dissolved, and its affairs shall be wound up, upon the first to occur of the following: (i) the termination of the legal existence of the last remaining Member of the Company or the occurrence of any other event which terminates the continued membership in the Company of the last remaining Member of the Company, unless the Company is continued without dissolution in a manner permitted by law or this Agreement; (ii) the entry of a decree of judicial dissolution under Section 18-802 of the Act; or (iii) a written agreement executed and delivered by each of the Members authorizing the dissolution of the Company.

Section 28. Entire Agreement. This Agreement constitutes the entire agreement of the parties with respect to the subject matter hereof.

Section 29. Governing Law. This Agreement shall be governed by and construed under the laws of the State of Delaware (without regard to conflict or choice of law principles that would cause the application of the internal laws of any other jurisdiction), and all rights and remedies shall be governed by said laws.
