Where indicated, we think you should revise your document in response to these comments. If you disagree, we will consider your explanation as to why our comment is inapplicable or a revision is unnecessary. Please be as detailed as necessary in your explanation. In some of our comments, we may ask you to provide us with supplemental information so we may better understand your disclosure.

Please have counsel confirm to us in writing that the reference and limitation to the DGCL includes the statutory provisions and all applicable provisions of the Delaware Constitution, including reported judicial decisions interpreting these laws. Please file this written confirmation as correspondence on EDGAR so that it will become part of the Commission`s official file regarding the related registration statement. Financial Statements Prior Comment No. 13 - Investment in Millennium Cell 2. We have considered your reply to this comment. It appears to us that the reduced value of this investment may be other than temporary. That decline does not have to be permanent in order for it to be other than temporary. We note that the valuations stated in your reply are intra-day trading values with closing prices considerably below the prices noted. We further note that (1) the company has sold, rather than held, some of this investments and (2) the current quote is less than $1.50 per share and has remained below $2.00 per share since June 2004. Without further support for maintaining the current carrying value, it appears that the investment should be written down accordingly. Please refer to the Staff Accounting Bulletin No. 59.M as well as EITF 03-01. Prior Comment No. 15 3. Please provide updated disclosure of the status of the arbitration issue noted in this prior comment. Closing As appropriate, please amend your registration statement in response to these comments.

Please understand that we may have additional comments after reviewing your amendment and responses to our comments.
