|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 small business issuer as of, and for,
    the periods presented in this report;                                                           
|   |                                                                                                                                                                                                                                                                                                                                                                          
|4. | The
    small business issuer’s other certifying officer(s) 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 small business issuer 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 small business issuer, including its consolidated subsidiaries, is made
    known to us by others within those entities, particularly during the period in which this 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 small business issuer’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                                                                                                                                         
| |     |                                                                                                                                                                                                                                                                                                                                                                                                                                                    
| | (d) | Disclosed
    in this report any change in the small business issuer’s internal control over financial reporting that occurred during
    the small business issuer’s most recent fiscal quarter (the small business issuer’s fourth fiscal quarter in the
    case of an annual report) that has materially affected, or is reasonably likely to materially affect, the small business issuer’s
    internal control over financial reporting; and



|5. | The
    small business issuer’s other certifying officer(s) and I have disclosed, based on our most recent evaluation of internal
    control over financial reporting, to the small business issuer’s auditors and the audit committee of the small business
    issuer’s board of directors (or persons performing the equivalent functions):
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (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 small business issuer’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 small business
    issuer’s internal control over financial reporting.
