   In our examination of documents for purposes of this opinion, we have
assumed, and express no opinion as to, the genuineness of all signatures on
original documents, the authenticity and completeness of all documents
submitted to us as originals, the conformity to originals and completeness of
all documents submitted to us as copies, the legal capacity of all persons and
entities executing the same, the lack of any undisclosed termination,
modification, waiver or amendment to any document reviewed by us and the due
authorization, execution and delivery of all documents where due authorization,
execution and delivery are prerequisites to the effectiveness thereof. We have
also assumed that the certificates representing the Shares will be, when
issued, properly signed by authorized officers of the Company or their agents.

   As to matters of fact relevant to this opinion, we have relied solely upon
our examination of the documents referred to above and have assumed the current
accuracy and completeness of the information obtained from records and
documents referred to above. We have made no independent investigation or other
attempt to verify the accuracy of any of such information or to determine the
existence or non-existence of any other factual matters; however, we are not
aware of any facts that would cause us to believe that the opinion expressed
herein is not accurate.

   We are admitted to practice law in the State of California, and we render
this opinion only with respect to, and express no opinion herein concerning the
application or effect of the laws of any jurisdiction other than, the existing
laws of the United States of America, of the State of California and, with
respect to the validity of corporate action and the requirements for the
issuance of stock, of the State of Delaware.

   In connection with our opinion expressed below, we have assumed that, at or
prior to the time of the delivery of the Shares, the Registration Statement
will have been declared effective under the Securities Act of 1933, as amended,
that the registration will apply to such Shares and will not have been modified
or rescinded and that there will not have occurred any change in law affecting
the validity or enforceability of the Shares.

   The Company has informed us that the Selling Stockholders may offer and sell
the Shares from time to time on a delayed or continuous basis. This opinion is
limited to the laws, including the rules and regulations, as in effect on the
date hereof. We undertake no responsibility to monitor the Company's or the
Selling Stockholder's future compliance with applicable laws, rules or
regulations of the Commission or other

governmental body. We also assume the Company will timely file any and all
supplements to the Registration Statement and Prospectus as are necessary to
comply with applicable laws in effect from time to time.

   Based upon the foregoing, it is our opinion that the 51,869,286 Shares to be
offered and sold by the Selling Stockholders when issued, sold and delivered in
the manner and for the consideration stated in the Registration Statement and
the Prospectus, and, with respect to the Financing Shares, in the manner and
for the consideration stated in the Purchase Agreement and related convertible
notes, will be validly issued, fully paid and nonassessable.

   We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to all references to us, if any, in the
Registration Statement, the Prospectus constituting a part thereof and any
amendments thereto. This opinion speaks only as of its date and we assume no
obligation to update this opinion should circumstances change after the date
hereof. This opinion is intended solely for use in connection with the offer
and sale of the Shares and is not to be relied upon for any other purpose.

                                          Very truly yours,

                                          FENWICK & WEST LLP
