I
have reviewed the interim filings (as this term is defined in Multilateral
Instrument 52-109 Certification of Disclosure in
Issuers’ Annual and Interim Filings) of Lorus for the interim
period ending November 30, 2008;
|
|
2.
|
Based
on my knowledge, the interim filings do not contain any untrue statement
of a material fact or omit to state a material fact required to be stated
or that is necessary to make a statement not misleading in light of the
circumstances under which it was made, with respect to the period covered
by the interim filings;
|
|
3.
|
Based
on my knowledge, the interim financial statements together with the other
financial information included in the interim filings fairly present in
all material respects the financial condition, results of operations and
cash flows of Lorus, as of the date and for the periods presented in the
interim filings.

|
The
issuer’s other certifying officers and I are responsible for establishing
and maintaining disclosure controls and procedures and internal control
over financial reporting for the issuer, and we
have:
|
|
|
a.
|
designed
such disclosure controls and procedures, or caused them to be designed
under our supervision, to provide reasonable assurance that material
information relating to the issuer, including its consolidated
subsidiaries, is made known to us by others within those entities,
particularly during the period in which the interim filings are being
prepared; and
|
|
|
b.
|
designed
such internal control over financial reporting, or caused it 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 the issuer’s GAAP;
and
|
|
5.
|
I
have caused the issuer to disclose in the interim MD&A any change in
the issuer’s internal control over financial reporting that occurred
during the three months ended November 30, 2008 that has materially
affected, or is reasonably likely to materially affect, the issuer’s
internal control over financial
reporting.
