No signature guarantee is required if either:

(a)

this Election to Participate and Exercise Warrants is signed by the registered holder of the Warrants exactly as the name of the registered holder appears in the book-entry notation representing the Warrants that were tendered with the Election to Participate and Exercise Warrants and the shares of Common Stock are to be issued in the name of the registered holder of the Warrants; or

(b)

the Warrants are tendered for the account of a member firm of a registered national securities exchange, a member of the Financial Industry Regulatory Authority, Inc., or a commercial bank or trust company (not a savings bank or savings and loan association) having an office, branch or agency in the United States which is a participant in an approval Signature Guarantee Medallion Program (each such entity, an “Eligible Institution”).

In all other cases, an Eligible Institution must guarantee all signatures on this Election to Participate and Exercise Warrants.

If a registered owner of Warrants wants to exercise Warrants pursuant to the Offer to Exercise, but the procedure for book-entry transfer cannot be completed on a timely basis or time will not permit all required documents to reach the Depositary Agent prior to the Expiration Date, such holder can still exercise their Warrants pursuant to the Offer to Exercise by complying with the following requirements:

(i)	the exercise must be made by or through an Eligible Institution;

(ii)

the Depositary Agent must receive by first-class mail delivery, overnight courier or facsimile on or prior to the Expiration Date, a properly completed and duly executed Notice of Guaranteed Delivery in the form the provided with the Offer to Exercise, with signatures guaranteed by an Eligible Institution and proper payment of the reduced exercise price of the Warrants; and

(iii)

the Depositary Agent must receive, within one NYSE trading day after the execution of the Notice of Guaranteed Delivery, as provided in the Offer to Exercise:

a.	a book-entry confirmation of the transfer of the registered owner’s Warrants into the Depositary Agent’s account;

b.	a signed copy of the Election to Participate and Exercise Warrants; and

c.	any other documents required by the Election to Participate and Exercise Warrants.

A holder is required to provide the Depositary Agent with a correct Taxpayer Identification Number (“TIN”) on Substitute Form W-9. The purpose for this form is explained below under “Important Tax Information.” The holder must, under penalties of perjury, certify that such number is correct and that such holder is not subject to backup withholding of federal income tax or, alternatively, to establish another basis for exemption from backup withholding. If a holder is subject to backup withholding, the holder must mark the “Notification of Backup Withholding” box. Failure to provide the information requested on the Substitute Form W-9 may subject the holder to a $50 penalty imposed by the Internal Revenue Service and to federal income tax backup withholding at the applicable federal withholding rate of any payments made to the holder or other payee.

Certain holders (including, for example, corporations, financial institutions, tax-exempt entities and IRA plans) are not subject to backup withholding. A foreign (“nonresident alien”) holder should submit an appropriate and properly completed IRS Form W-8, a copy of which may be obtained from the Depositary Agent, in order to avoid backup withholding. We cannot accept a facsimile, photocopy or scanned image of a Form W-8BEN.

The Election to Participate and Exercise Warrants, the Warrants, and the exercise price must be received at the address below on or before the Expiration Date of 5:00 p.m. (Eastern Time) on March 31, 2025, as may be extended by the Company in its sole discretion. The method of delivery of all documents is at the election and risk of the tendering Warrant holder, and the delivery will be deemed made only when actually received by the Depositary Agent. If delivery is by mail, registered mail with return receipt requested, properly insured, is recommended. In all cases, sufficient time should be allowed to ensure timely delivery.

IMPORTANT TAX INFORMATION

Under the federal income tax law, unless an exemption applies, a holder whose tendered Warrants are accepted for payment is required to provide the Depositary Agent with such holder’s correct TIN on the Substitute Form W-9. If such holder is an individual, the TIN is such holder’s Social Security Number. If the Depositary Agent is not provided with the correct TIN, the holder may be subject to a $50 penalty imposed by the Internal Revenue Service. In addition, payments that are made to such holder may be subject to backup withholding based on the applicable tax rate of the reportable amount.

Certain holders (for example, corporations) are not subject to these backup withholding and reporting requirements. In order for a non-U.S. person to claim nonresident alien (or foreign) tax status and qualify for an exemption from backup withholding, such individual must submit an appropriate and properly completed IRS Form W-8, attesting to that individual’s foreign status. Normally, a foreign individual or corporation will provide a Form W-8BEN. Intermediary entities will provide a Form W-8IMY for the entity and a Form W-8BEN or Form W-9 for each beneficial owner along with a withholding statement. Such a Form W-8 may be obtained from the Depositary Agent. Exempt U.S. holders, other than foreign individuals (i.e., corporations, etc.) should furnish their TIN, check the “Exempt payee” line and sign, date and return the Substitute Form W-9 to the Depositary Agent.

If backup withholding applies, the Depositary Agent is required to withhold a percentage of any reportable payments made to the holder at the withholding rate. Backup withholding is not an additional tax. Rather, the federal income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If backup withholding results in an overpayment of taxes, a refund may be obtained from the Internal Revenue Service when completing a tax return for that applicable year, based on the withholding amount reported on the Form 1099.

Purpose of Substitute Form W-9

To prevent backup withholding on payments that are made to a holder with respect to Warrants tendered pursuant to the Offer to Exercise, the holder is required to notify the Depositary Agent of such holder’s correct TIN (or the TIN of another payee) by completing the Substitute Form W-9 enclosed certifying that the TIN provided is correct.

NOTICE TO NON-RESIDENT ALIEN INDIVIDUALS OR FOREIGN ENTITIES (e.g. foreign corporation, partnership or trusts): DO NOT COMPLETE THE ABOVE SUBSTITUTE FORM W-9. NRA INDIVIDUALS SHOULD COMPLETE THE APPLICABLE FORM W-8BEN. FORMS ARE AVAILABLE AT www.irs.gov. FOREIGN ENTITIES NEED TO COMPLETE THE APPLICABLE TYPE OF FORM W-8 AND RETURN THAT CERTIFICATION OF FOREIGN TAX STATUS. FAILURE TO COMPLETE THE FORM WILL SUBJECT THE RECIPIENT TO THE APPLICABLE FEDERAL TAX INCOME TAX WITHHOLDING.
