We, as your counsel, have examined originals or copies of such documents, corporate records, certificates of public officials and other instruments as we have deemed necessary or advisable for the purpose of rendering this opinion.

Based upon the foregoing, and subject to the additional assumptions and qualifications set forth below, we advise you that, in our opinion, as of the date hereof, the Securities have been duly authorized and, when and to the extent issued, delivered and paid for in accordance with the Plans, the Securities will be validly issued, fully paid and non-assessable.
 
We are members of the Bar of the State of California and the foregoing opinion is limited to the General Corporation Law of the State of Delaware.
 

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement.  In giving this consent, we do not admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act.
