−Removed: Remediation of material weakness
−Removed: As previously disclosed, the Company had ineffective controls over the evaluation and accounting for complex financing transactions, specifically, the Company did not have sufficient technical resources to appropriately identify errors in the accounting for warrants issued in a registered offering including whether the warrants should be classified as a liability or as equity. 
−Removed:  The control deficiency described above created a reasonable possibility that a material misstatement to the consolidated financial statements would not be prevented or detected on a timely basis. This material weakness resulted in a material adjustment to the classification of certain warrants issued in December 2020 from equity to a liability on the consolidated balance sheet.
−Removed: The classification error was corrected prior to issuance of the consolidated financial statements as of and for the year ended December 31, 2020.
−Removed: On January 1, 2021, the Company early adopted ASU 2020-06 which resulted in the elimination of the criteria that resulted in the warrants being classified as liabilities at December 31, 2020. 
−Removed: The remedial actions taken included educating and re-training control owners regarding the accounting standards related to the accounting for complex financial instruments and contracting with appropriate resources to provide accounting interpretation guidance to assist us in identifying and addressing any issues that affect our consolidated financial statements.
−Removed: In addition, management enhanced the accounting policy, controls and review procedures related to the accounting for complex financial instruments. Management has implemented these remedial actions to ensure that the underlying causes of the material weakness are remediated such that the existing controls operate effectively.
−Removed: We tested our newly established policies, procedures and control activities designed to address the above-described material weakness, and as a result, we believe that the material weakness was remediated as of December 31, 2021. 
+Added: Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of our disclosure controls and procedures as of December 31, 2022, pursuant to Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act).
+Added: Our disclosure controls and procedures are designed to ensure that information required to be disclosed in our reports that are filed or furnished under the Exchange Act are recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our Company's reports filed or furnished under the Exchange Act is accumulated and communicated to the Company’s management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.
+Added: Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
+Added: Based on the evaluation of our disclosure controls and procedures as of December 31, 2022, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.
