Whether you hold shares directly as the stockholder of record or beneficially in street name, you may direct how your shares are voted without attending the Annual Meeting. If you are a stockholder of record, you may submit your voting instructions by proxy. You can submit your proxy over the internet, by mail or by telephone by following the instructions provided in the “Proxy Summary” or on your proxy card or notice of internet availability. The persons named as attorneys-in-fact and proxies in the proxy, Jason Few and Joshua Dolger, were selected by our Board.

A stockholder may change its voting instructions and/or revoke its proxy at any time prior to the vote at the Annual Meeting. A stockholder of record may change its voting instructions or revoke its proxy by granting a new proxy bearing a later date (which automatically revokes the earlier proxy) using any of the methods described above (and until the applicable deadline for each method), by providing a written notice of revocation to the Corporate Secretary of the Company or by voting in person at the Annual Meeting (by attending the virtual Annual Meeting and voting online). Attendance at the Annual Meeting will not cause a stockholder’s previously granted proxy to be revoked unless such stockholder specifically so requests in writing or such stockholder votes in person at the Annual Meeting (by attending the virtual Annual Meeting and voting online). Stockholders who hold their shares beneficially in street name may change their voting instructions by submitting new voting instructions to their broker, trustee or nominee following the instructions it has provided, or by attending the virtual Annual Meeting and voting online. All expenses incurred in connection with the solicitation of proxies will be borne by the Company. In addition to soliciting proxies through the mail, the Company may solicit proxies through its Directors and employees (for no additional compensation) in person or by telephone. We have also hired Sodali & Co to assist in the solicitation of proxies. Fees for this service are estimated to be approximately $30,000, plus out-of-pocket expenses. Brokerage firms, nominees, custodians and fiduciaries also may be requested to forward proxy materials to the beneficial owners of shares held of record by them and will be reimbursed for their reasonable expenses.

If you need assistance in completing your proxy card or have questions regarding the Annual Meeting, please contact Sodali & Co, the proxy solicitation agent for the Company, by telephone at (800) 662-5200 (toll free) or by email at FCEL@investor.sodali.com.
