OfficerPursuant to 18 U.S.C. 1350(Section 302 of the Sarbanes-Oxley Act
of 2002) I, Dr. Thomas Drees, certify that: 1.
  I have reviewed this quarterly report on Form 10-Q of SANGUINE
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 quarterly report, fairly present in all material
respects the financial condition, 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)) and internal control over financial
reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the
registrant and have;  (a)  Designed such
disclosure controls and procedures 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)  Designed such
internal control over financial reporting, or caused such internal control over
financial reporting to be designed under our supervision, to provide reasonable
assurance regarding the reliability of financial reporting and the preparation
of financial statements for external purposes in accordance with generally
accepted accounting principles;  (c)  Evaluated the
effectiveness of the registrant's disclosure controls and procedures as of a
date within 90 days prior to the filing date of this quarterly report (the
"Evaluation Date") 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  (d)  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 (the
registrants fourth fiscal quarter in the case of an quarterly report) 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, to the registrant's auditors and the audit
committee of registrant's board of directors (or persons performing the
equivalent functions): (a)  All significant deficiencies in the design or operation of
internal controls which could adversely affect the registrant's ability to
record, process, summarize and report financial data and have identified for the
registrant's auditors, any material weaknesses in internal controls; and (b)  Any fraud, whether or not material, that
involves management or other employees who have a significant role in the
registrant's internal controls; and Date: May
