         This 13G is being jointly filed by Tortoise Capital Advisors LLC, a
Delaware limited liability company ("TCA"), and Tortoise Energy Infrastructure
Corporation, a Maryland corporation ("TYG").

         TCA and TYG have entered into an Agreement Regarding Joint Filing of
13G dated February 11, 2005 (the "Agreement") pursuant to which TCA and TYG
have agreed to file this 13G jointly in accordance with the provisions of Rule
13d-1(k)(1) of the Securities Exchange Act of 1940,as amended (the "Act"). A
copy of the Agreement is attached hereto as Exhibit A.

Item 3   The Reporting Person is:

ss. 240.13d-1(b)(1)(ii)(E), and TYG is an investment company registered under
Section 8 of the Investment Company Act of 1940 (15 U.S.C. 80a-8).

Item 4   Ownership:

         TCA acts as an investment advisor to TYG, a closed-end investment
company registered under the Act. TCA, by virtue of an Investment Advisory
Agreement with TYG, has all investment and voting power over securities owned of
record by TYG. However, despite its delegation of investment and voting power to
TCA, TYG may be deemed to be the beneficial owner under Rule 13d-3 of the Act,
of the securities it owns of record because it has the right to acquire
investment and voting power through termination of the Investment Advisory
Agreement. Thus, TCA and TYG have reported that they share voting power and
dispositive power over the securities owned of record by TYG. TCA also acts as
an investment advisor to certain managed accounts. Under contractual agreements
with individual account holders, TCA, with respect to the securities




held in the managed accounts, shares investment and voting power with certain
account holders, and has no voting power but shares investment power with
certain other account holders. TCA may be deemed the beneficial owner of the
securities covered by this statement under Rule 13d-3 of the Act. None of the
securities listed below are owned of record by TCA, and TCA disclaims any
beneficial interest in such shares.
