<div align='center'>PROPOSAL 2 — RATIFICATION OF APPOINTMENT
OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM</div>

Our Audit Committee has appointed Baker Tilly US, LLP (Campbell, CA, PCAOB ID: 23) (“Baker Tilly”) as our independent registered public accounting firm for the fiscal year ending December 31, 2025.

Moss Adams LLP (“Moss Adams”) had audited the Company’s financial statements since 2013. On June 3, Moss Adams notified us that it merged with Baker Tilly effective on June 3, 2025. The combined audit practices operate as Baker Tilly US, LLP. The Audit Committee and the Board seek to have the stockholders ratify the Audit Committee’s appointment of Baker Tilly.

Although we are not required to seek stockholder approval of this appointment, the Board considers the selection of the independent registered public accounting firm to be an important matter of stockholder concern and is submitting the appointment of Baker Tilly for ratification by stockholders as a matter of good corporate practice. If the appointment of Baker Tilly is not ratified by the stockholders, the Audit Committee will consider the vote of our stockholders and may appoint another independent registered public accounting firm or may decide to maintain its appointment of Baker Tilly.

Representatives of Baker Tilly will be present at the Annual Meeting and will have the opportunity to make a statement, if they desire to do so, and to respond to appropriate questions.
