The Company expects to file its Quarterly Report on Form 10-Q after

the market closes on Monday, November 21, 2022. As described in the Company's Current Report on Form 8-K that was filed on November

10, 2022, the Company is making this filing on a delayed basis to allow time to restate its financial statements for the quarters ended

March 31, 2022 and June 30, 2022. This restatement is being made to correct a mistake related to deferred compensation expense (consisting

of earned and unused paid time off) that resulted in the understatement of administrative expenses by approximately $222,000 during the

first quarter of 2022. This correction had no impact on the Company's cash position or product sales.

The Company anticipates no change to the preliminary sales results

for the third quarter of 2022 that were disclosed on October 5, 2022.
