| | 1. I have reviewed this quarterly report on

|
| | 2. Based on my knowledge, this 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
    report;
|
| | 3. Based on my knowledge, the financial
    statements, and other financial information included in this
    report, fairly present in all material respects the financial
    condition, results of operations and cash flows of the

|
| | 4. The registrants other certifying
    officer(s) and I are responsible for establishing and

| | a) Designed such disclosure controls and
    procedures, or caused such disclosure controls and procedures to
    be designed under our supervision, to ensure that material

    those entities, particularly during the period in which this
    report is being prepared;

    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

    the registrants internal control over financial reporting

    reasonably likely to materially affect, the registrants
    internal control over financial reporting; and



| |                                                                                                                                                                                                                                                                                                                          
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| | 5. The registrants other certifying
    officer(s) 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 functions):



| |                                                                                                                                                                                                                                                                                              
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| | a) all significant deficiencies and material
    weaknesses in the design or operation of internal controls 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.
