Exhibit 4.35

As of March 30, 2011

This Amendment Agreement (this “Agreement”) is entered into by and among IASO Pharma Inc. (f/k/a Pacific Beach Biosciences, Inc.), a Delaware corporation (the “Company”), and The Xxxxxxx X. Xxxxxxxxx 2000 Family Trusts Dated December 15, 2000 (“Holder”).

RECITALS

WHEREAS, Holder is the holder of an Amended and Restated Future Advance Promissory dated as of September 30, 2009 made by the Company in favor of Holder (as previously amended, the “Note”);

WHEREAS, the Company filed a registration statement with the SEC and conducted a road show for a proposed initial public offering (“IPO”) of the Company’s securities led by Ladenburg Xxxxxxxx & Co. Inc. (“Ladenburg”) in February 2011; however, despite the considerable efforts of all involved, the IPO failed to price and was not consummated;

WHEREAS, the Company has determined that it is in the best interest of the Company and its stockholders to obtain interim financing and retain its lead asset is to conduct a rights offering (the “Rights Offering”) to its existing convertible noteholders, including the Holders, of a new issue of secured convertible notes in the aggregate principal amount of $3,000,000 (the “Rights Offering Notes”), with each existing convertible noteholder, including the Holders entitled to purchase up to $281 in principal amount of Rights Offering Notes for each $1,000 of original principal amount of existing convertible notes held by such noteholder. The Rights Offering Notes will be secured by all the assets of the Company and will be convertible into 100% of the equity of the Company immediately prior to an IPO; provided, however, that the Company will have the right to repay up to $1 million of the Rights Offering Notes out of the proceeds of an IPO. The terms of the Rights Offering will be more fully described in the Subscription Form and Subscription Agreement that will be circulated to you once the Requisite Approval (as defined below) is obtained in connection with this Agreement;

WHEREAS, the Rights Offering will be backstopped by Xx. Xxxxxxx X. Xxxxxxxxx and Manchester Securities Corp. (“Manchester”) (or their respective affiliates), the Company’s two largest investors. As compensation for their backstop commitment, Xx. Xxxxxxxxx and Manchester will receive warrant coverage to purchase shares equal to 100% of their backstop commitment amounts; however, Xx. Xxxxxxxxx will assign his backstop warrants to all the existing convertible noteholders of the Company (other than Manchester) on a pro rata basis. The backstop warrants to be issued to Manchester will contain certain anti-dilution protections that will not be in the warrants to be issued to Xx. Xxxxxxxxx. In addition, following consummation of the Rights Offering, Manchester and Xx. Xxxxxxxxx will have the right to consent to any material action taken by the Company prior to the consummation of an IPO and Manchester will have the right to designate one member of the Company’s board of directors;

WHEREAS, the Rights Offering is designed as a bridge to a larger financing, ideally an IPO. With respect to the larger financing, the Company has engaged in discussions with OPN Capital Markets, a division of National Securities (“OPN”), to act as co-lead underwriter in connection with an IPO. OPN is a joint venture of Opus Point Partners and National Securities. Xx. Xxxxxxxxx is a principal of Opus Point Partners, which is a significant shareholder of National Securities. Based on discussions with OPN and feedback from Ladenburg, the Company believes it is imperative that the Company effect a recapitalization that permits a lower pre-money valuation to give it the best chance for successfully

completing an IPO. As such, the Company is seeking to effect a substantial recapitalization that would amend, in accordance with the terms set forth herein, the Note and all the Company’s other existing convertible notes;

WHEREAS, in connection with the proposed recapitalization and the Rights Offering, all of the Company’s investor warrants will be terminated and the Company will effect a reverse stock split so that all of the current equity in the Company is effectively eliminated, and the shares into which the Rights Offering Notes convert will represent substantially all of the capital stock in the Company immediately prior to the consummation of an IPO. Following the proposed recapitalization and the Rights Offering, the only debt the Company will have outstanding will be amounts borrowed under its bank line of credit, which amounted to $325,000 as of December 31, 2010 and which is expected to be repaid with the proceeds of an IPO, and the notes issued to Paramount Credit Partners in the aggregate amount of $2,875,000, which are not convertible and will not be repaid with the proceeds of an IPO;

WHEREAS, the Company seeks the consent of the Holder to amend the Note to provide that the Note will convert into the right to receive Milestone Payments (as defined herein) upon the consummation of the Rights Offering, on the terms set forth herein, in order to effect the proposed recapitalization and maximize the Company’s ability to complete an IPO; and

WHEREAS, the Holder agrees to amend the Note on the terms set forth herein;
