CALCULATION OF FILING FEE:

Transaction Valuation:		Amount of Filing Fee:
$8,588,792.42(a)		$1,069.30(b)

(a)	Estimated for purposes of calculating the amount of the filing fee only. The transaction is an offer by the Cardax, Inc. (the “Company”) to holders of its $0.625 warrants (“Original Warrants”) to exchange up to 27,705,782 of such Original Warrants, plus a fee of $0.15 per Original Warrant (“Exchange Payment”) for an equal number of shares of common stock of the Company (“Exchange Offer”). The transaction valuation is calculated pursuant to Rule 0-11 of the Securities Exchange Act of 1934, as amended. The transaction valuation assumes that 27,705,782 outstanding Original Warrants are tendered in the Exchange Offer, and was determined using $0.31 per Original Warrant, which represents the average of the bid and ask price of the Company’s common stock on May 1, 2018 on the OTCQB.
