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

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. I am responsible for establishing and maintaining
disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e) and 15d-15(e)) and internal control over financial
reporting (as defined in Exchange Act Rules 13a-15(f) and 15(d)-15(f)) for the registrant and have:



(a) designed such disclosure controls
and procedures, or caused such disclosure controls and procedures to be designed under my 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) designed such internal control
over financial reporting, or caused such internal control over financial reporting to be designed under my 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;

of the registrant’s disclosure controls and procedures and presented in this report my 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 quarter in the case of an annual report) that has materially affected, or is reasonably
likely to materially affect, the registrant’s internal control over financial reporting.



5. I have disclosed, based on my most recent
evaluation, 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
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.
