1934, as amended), as of the end of the period covered by this Quarterly Report on Form 10-Q.

in Internal Control over Financial Reporting .

Other than the remediation discussed below, there were no changes in our

internal control over financial reporting during the quarter ended January 31, 2022 that have materially affected, or are reasonably

likely to materially affect, our internal control over financial reporting.

Reported Material Weakness

Management previously

identified a material weakness in internal control over financial reporting related to accounting for taxes, which is disclosed in Item

“Controls and Procedures” of our Form 10-K for the fiscal year ended July 31, 2021.

Specifically, we determined that

our management review controls related to valuation allowance against deferred tax assets were ineffective.

In order to remediate the material

weakness, we designed and implemented the following internal controls:

We have historically engaged tax consultants to prepare

and review the Company’s income tax provision.

The tax consultants appointed a second tax partner as an independent reviewer

to perform a final review of the tax provision work prepared by its engagement team.

The chief financial officer performed a final review

of the tax provision, which is performed at a more granular level than in the past, and performed at a sufficient level of precision.

This review involves a detailed review of the tax provision schedules prepared by the tax consultants.

This includes,

among other procedures, assessing the completeness and accuracy of amounts included in the tax provision schedules, reconciling amounts

in the tax provision schedules to the Company’s records, reviewing the mathematical accuracy of the schedules, understanding

key fluctuations in the tax accounts, and reviewing that amounts recorded in the financial statements for income taxes reconciles

to the tax provision schedules.

We believe our material weakness related to accounting for taxes has been

remediated and that our internal control processes over financial reporting are effective as January 31, 2022.
