Acknowledgement of Receipt of the Consent Solicitation Materials.  Each Consenting Holder acknowledges that he, she or it has received a copy of the Consent Solicitation Statement, this Agreement and the Joinder (collectively, the “Consent Solicitation Materials”) and has had an opportunity to review the Consent Solicitation Materials and to discuss with his, her or its legal, tax and other advisors the terms of the Solicitation and the effects of the Waiver to the extent such Consenting Holder deemed necessary or advisable to determine whether or not to consent to the Waiver.

Terms and Conditions of the Solicitation.  The terms and conditions of the Solicitation set forth in the Consent Solicitation Materials are hereby incorporated by reference as if set forth fully in this Agreement.  Each Consenting Holder acknowledges that the Company has the right, in its sole discretion, to extend or terminate the Solicitation or to change the terms thereof.

Irrevocable Consent to Waiver.  Effective as of the Effective Date, each Consenting Holder hereby irrevocably consents to the waiver of, and does hereby permanently and irrevocably waive on behalf of such Consenting Holder and such Consenting Holder’s heirs, successors and assigns, the Series B Exchange Right for any Subsequent Financing occurring on or after January 1, 2022. Each Consenting Holder hereby agrees and acknowledges that this Agreement (and any Joinder hereto) is being delivered to the Company and shall constitute a consent of the stockholders of the Company in lieu of a meeting of stockholders pursuant to Section 228 of the Delaware General Corporation Law, and hereby approves the Waiver with respect to the number of shares of Series B Preferred Stock set forth in such Consenting Holder’s Joinder (it being understood that if no number of shares is included in such Consenting Holder’s Joinder, such Consenting Holder shall be deemed to have consented to the Waiver with respect to all of such Consenting Holder’s shares of Series B Preferred Stock).  Each Consenting Holder acknowledges that if the Requisite Consents are received and the other conditions to the Solicitation are satisfied or waived, pursuant to Section 13 of the Certificate of Designations, the Waiver shall become effective as to all present and future holders of shares of Series B Preferred Stock then outstanding, including shares held by Holders who do not become Consenting Holders.  Each Consenting Holder further acknowledges that this consent is irrevocable and may not be withdrawn or revoked by such Consenting Holder.

Notice of Waiver.  Effective as of the Effective Date, each Consenting Holder hereby consents to the imposition of a legend or other notice of the Waiver on the books and records evidencing such Holder’s Series B Preferred Stock maintained by the transfer agent for the Series B Preferred Stock and the imposition of a similar legend on any physical share certificate evidencing the Holder’s Series B Preferred Stock.  The Consenting Holder acknowledges and agrees that such legend and notice will be made or imposed on all of the Consenting Holder’s shares of Series B Preferred Stock even if the Consenting Holder’s consent relates to less than all of the Consenting Holder’s shares of Series B Preferred Stock.

Series B Warrants.  The Consenting Holder shall specify in his, her or its Joinder the number of Series B Warrants owned by the Consenting Holder.  In the event that the Consenting Holder does not specify the number of Series B Warrants so owned by the Consenting Holder, the number of Series B Warrants set forth on the books and records of the Company shall be deemed to be the number of Series B Warrants owned by the Consenting Holder for all purposes of this Agreement.  In the event of a discrepancy between the number of Series B Warrants specified in the Joinder and the number of Series B Warrants set forth on the books and records of the Company, the Consenting Holder acknowledges that the Consenting Holder’s Joinder will be deemed to be defective and the Company will have the right to require the Consenting Holder to correct the Joinder prior to the Expiration Date or may reject the Joinder in its entirety, in its sole discretion.  The Consenting Holder acknowledges that as described in the Consent Solicitation Materials, neither the Company nor any other person shall have any obligation to notify the Consenting Holder of any error or defect in the Consenting Holder’s Joinder.

Exercise Price Reduction.  Subject to the satisfaction or waiver of the conditions of the Solicitation, at the Effective Date, the Consenting Holder’s Series B Warrants shall be deemed to be automatically, and without any action on the part of the Consenting Holder, amended to effect the Exercise Price Reduction. If the Consenting Holder’s Joinder relates to less than all of the shares of Series B Preferred Stock owned by the Consenting Holder on the Record Date, the Exercise Price Reduction will only apply to the same proportion of Series B Warrants owned by such Consenting Holder as the proportion of the number of shares of Series B Preferred Stock owned by such Consenting Holder in respect of which a Joinder has been timely executed and delivered by such Consenting Holder.

Replacement Warrants.  Subject to the satisfaction or waiver of the conditions of the Solicitation, following the Effective Date, the Company shall promptly deliver to the Consenting Holder, upon request of a Consenting Holder, amended Series B Warrants that reflect the Exercise Price Reduction in exchange for the surrender for cancellation of the Consenting Holder’s Series B Warrants entitled to the Exercise Price Reduction as provided herein.
