reviewed this quarterly report on Form 10-Q of  Eden Bioscience Corporation;

2.  Based on my
knowledge, this quarterly report does not  contain any untrue statement of a material
fact or omit to  state a material fact necessary to make the statements made,  in light
of the circumstances under which such statements  were made, not misleading with respect
to the period covered  by this quarterly report;

3.  Based on my
knowledge, the financial statements, and  other financial information included in this

results of operations and cash flows of  the registrant as of, and for, the periods
presented in this  quarterly report;

4.  The
registrants other certifying officer and I are  responsible for establishing and
maintaining disclosure  controls and procedures (as defined in Exchange Act Rules
13a-15(e) and 15d-15(e)) for the registrant and have:

a)  Designed
such disclosure controls and procedures, or  caused such disclosure controls and
procedures to be  designed under our supervision, to ensure that material  information
relating to the registrant, including its  consolidated subsidiaries, is made known to us
by others  within those entities, particularly during the period in  which this quarterly
report is being prepared;

b)  Evaluated
the effectiveness of the registrants  disclosure controls and procedures and
presented in this  report our conclusions about the effectiveness of the  disclosure
controls and procedures, as of the end of the  period covered by this report based on
such evaluation; and

c)  Disclosed
in this report any change in the registrant's  internal control over financial reporting
that occurred  during the registrant's most recent fiscal quarter that has  materially
affected, or is reasonably likely to materially  affect, the registrant's internal
control over financial  reporting; and

5.  The
registrants other certifying officer and I have  disclosed, based on our most
recent evaluation of internal  control over financial reporting, to the registrants
auditors and the audit committee of the registrants board  of directors (or persons
performing the equivalent function):

a)  all
significant deficiencies and material weaknesses in  the design or operation of internal
control over financial  reporting which are reasonably likely to adversely affect  the
registrants ability to record, process, summarize and  report financial
information; and

b)  any fraud,
whether or not material, that involves  management or other employees who have a
significant role in  the registrants internal control over financial reporting.
