All advances and all unpaid interest accrued under this Note (collectively, the “Term Loan Balance”) may, at the option of the Holder and upon five (5) days prior written notice (pursuant to the form of notice attached hereto as Exhibit A), be converted in whole or in part into a number of shares of Common Stock of Flux Power Holdings, Inc.

In any such case, appropriate adjustment will be made in the application of the provisions of this paragraph with respect to the rights of the Holder after the Capital Reorganization to the end that the provisions of this paragraph (including adjustment of the Conversion Price then in effect and the number of shares issuable upon conversion of the Term Loan Balance) will be applicable after that event and be as nearly equivalent as practicable.

(d) Certificate As To Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price, Flux Power at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to the Holder a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment are based and shall file a copy of such certificate with its corporate records.
