                  This opinion is limited to the laws of the State of Delaware
(excluding the securities laws and blue sky laws of the State of Delaware), and
we have not considered and express no opinion on the laws of any other
jurisdiction, including federal laws and rules and regulations relating thereto.
Our opinions are rendered only with respect to Delaware laws and rules,
regulations and orders thereunder which are currently in effect.

                  Based upon the foregoing, and upon our examination of such
questions of law and statutes of the State of Delaware as we have considered
necessary or appropriate, and subject to the assumptions, qualifications,
limitations and exceptions set forth herein, we are of the opinion that:

                  1. Company V has been duly formed and is validly existing in
good standing as a limited liability company under the Delaware Limited
Liability Company Act (6 Del. C. Section 18-101, et seq.) (the "LLC Act").

                  2. The Company V Preferred Securities will represent valid
and, subject to the qualifications set forth in paragraph 3 below, fully paid
and nonassessable limited liability company interests in Company V.

                  3. The Company V Preferred Securityholders shall not be
obligated personally for any of the debts, obligations or liabilities of Company
V, whether arising in contract, tort or otherwise solely by reason of being a
member of Company V, except as a Company V Preferred Securityholder may be
obligated to repay any funds wrongfully distributed to it. We note that the
Company V Preferred Securityholders may be obligated to make payments as set
forth in the Company V LLC Agreement.

entitled to the same limitation of personal liability extended to stockholders
of private corporations for profit organized under the General Corporation Law
of the State of Delaware (the "GCL"). We note that the Trust V Holders may be
obligated to make payments as set forth in the Trust V Agreement.

                  7. Company VI has been duly formed and is validly existing in
