I previously received a copy of Pure Bioscience, Inc.’s (the “Company”) Offer to Amend and Exercise Warrants to Purchase Common Stock, dated August 25, 2017, and any amendments thereto (the “Offer to Amend and Exercise”). I elected to participate in the Offer to Amend and Exercise by executing and delivering an Election to Participate and Exercise Warrants and the documents required thereby.

I understand that I may submit this Notice of Withdrawal to the Company at any time prior to 5:00 p.m. (Pacific Time) on September 25, 2017 or if the Notice of Approval of Aggregate Warrant Amendment Offer is sent to me with respect to the 2014 Warrants, 2015 Warrants and/or 2017 Warrants and I did not submit an election to participate in the Offer to Amend and Exercise prior to the Expiration Date but subsequently submitted such election, I will have until 5:00 p.m. (Pacific Time) on October 10, 2017 to submit this Notice of Withdrawal with respect to the 2014 Warrants, 2015 Warrants and/or 2017 Warrants, respectively, as may be extended by the Company in its sole discretion.

I hereby irrevocably withdraw my previously submitted election to participate in the Offer to Amend and Exercise and reject the Offer to Amend and Exercise.

I understand that by rejecting the Offer to Amend and Exercise, (a) if the 2014 Requisite Majority, 2015 Requisite Majority and/or 2017 Requisite Majority elect to participate in the Offer to Amend and Exercise, my 2014 Warrant, 2015 Warrant and/or 2017 Warrant, respectively, will be amended pursuant to the terms of the Offer to Amend and Exercise and will expire unexercised on October 10, 2017 if I do not exercise such Original Warrant as amended by the terms of the Offer to Amend and Exercise or (b) if the 2014 Requisite Majority, 2015 Requisite Majority and/or 2017 Requisite Majority do not elect to participate in the Offer to Amend and Exercise, my 2014 Warrant, 2015 Warrant and/or 2017 Warrant, respectively, will remain unmodified and in full force and effect.

All capitalized terms used but not defined herein shall have the meanings ascribed to the Offer to Amend and Exercise. I waive any right to receive any notice of the acceptance of this Notice of Withdrawal.
