Section 3.6 No Insolvency Proceedings. No bankruptcy or similar insolvency proceeding has been filed, or is currently contemplated, with respect to Williams.

(a) Williams acknowledges that (i) the Partnership intends the offer and issuance of the Class A Units hereunder to be exempt from registration under the Securities Act and applicable state securities laws by virtue of the status of Williams as an “accredited investor” within the meaning of Rule 501(a) of Regulation D under the Securities Act (“Regulation D”) acquiring such Class A Units in transactions exempt from registration pursuant to Rule 506 of Regulation D, and (ii) in issuing any Class A Units pursuant to the terms of this Agreement, the Partnership is relying on the representations made by Williams as follows:

(b) Williams has had access to and has received such financial and other information regarding the Partnership as Williams deems necessary in order to make its investment decision to acquire the Class A Units to be issued to Williams hereunder. Williams has not relied on representations, warranties, opinions, projections, financial or other information or analysis, if any, supplied to it by any person other than the Partnership, its Affiliates or its representatives.

(c) Williams is a sophisticated investor and has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of the acquisition of the Class A Units hereunder, and Williams is able to bear the economic risks of

such an investment. Williams is aware that it may be required to bear the economic risk of an investment in the Class A Units for an indefinite period of time, and it is able to bear such risk for an indefinite period. Williams has relied upon its own tax, legal and financial advisors in connection with its decision to acquire the Class A Units issued to Williams hereunder. Williams is an “accredited investor” within the meaning of Rule 501(a) of Regulation D.

(d) Williams is acquiring the Class A Units to be issued hereunder for its own account and not with a view to or for the purposes of resale, distribution or fractionalization, in whole or in part, of such Class A Units.

(e) Williams acknowledges that the Class A Units to be issued hereunder has not been registered under the Securities Act and is being offered and sold to Williams in reliance on specific exemptions from the registration requirements of U.S. securities laws and that the Partnership is relying upon the truth and accuracy of the representations and warranties of Williams set forth in this Section 3.6 in order to determine the applicability of such exemptions and the suitability of Williams to acquire the Class A Units. Williams agrees that if any such representation and warranty made in this Section 3.6 is no longer accurate, it shall promptly notify the Partnership. Williams acknowledges that if it decides to resell or otherwise transfer any of its Class A Units, then such shares may be resold or transferred only if sold in a transaction that does not require registration under the Securities Act or any applicable laws of the states of the United States.

(f) Williams agrees that so long as the Class A Units to be issued to Williams hereunder are “restricted securities” as defined in Rule 144 under the Securities Act, it shall notify each transferee of any shares of Class A Units from it that (i) such shares have not been registered under the Securities Act, (ii) such shares are subject to the restrictions on the resale or other transfer thereof described in paragraph (e) above, (iii) such transferee shall be deemed to have represented (x) as to its status as a purchaser acquiring such shares in a transaction that does not require registration under the Securities Act or any applicable laws of the states of the United States and (y) that such transferee is not an “underwriter” within the meaning of Section 2(11) of the Securities Act and (iv) such transferee shall be deemed to have agreed to notify its subsequent transferees as to the foregoing.

Except as set forth in the Registration Statement, the Partnership represents and warrants to Williams as follows:
