Exhibit 4.26



AMENDMENT AGREEMENT


December 23, 2010

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 each holder of 2010 Notes (as such term is defined below) listed on the signature pages hereto (together with successors and assigns of each, a “Holder,” and collectively, the “Holders”), and solely with respect to Sections 6 and 8 of this Agreement, Lindsay A. Rosenwald, M.D., Paramount Biosciences, LLC, The Lindsay A. Rosenwald 2000 Family Trusts Dated December 15, 2000 and Capretti Grandi, LLC.

RECITALS

WHEREAS, each Holder and the Company are parties to a Note Purchase Agreement dated as of February 9, 2010 or March 1, 2010 (collectively, the “Purchase Agreements”), pursuant to which the Company issued and sold to the Holders a series of like senior convertible promissory notes in the aggregate principal amount of $4,343,000 (collectively, as previously amended, the “2010 Notes”) and a series of like warrants to purchase shares of the Company’s common stock, par value $0.001 per share (collectively, the “Warrants”);

WHEREAS, the Company is currently in the process of registering a proposed initial public offering of the Company’s securities, which the Company anticipates will qualify as a Qualified IPO (as defined in 2010 Notes) (the “IPO”);

WHEREAS, the Company had previously engaged Maxim Group LLC (“Maxim”) as the lead underwriter in connection with the IPO; however, Maxim recently represented to the Company that Maxim will not be able to raise the funds the Company requires in the IPO and, therefore, the Company has recently engaged Ladenburg Thalmann & Co. Inc. (“Ladenburg”) to replace Maxim as the Company’s lead underwriter in connection with the IPO;

WHEREAS, Ladenburg, as the new lead underwriter for the IPO, has stressed to the Company that the existence of the conversion discount at which the 2010 Notes and the Company’s other existing convertible debt will convert into equity securities in connection with the IPO significantly inhibits the ability of the Company to successfully complete the IPO and, therefore, Ladenburg has recommended that the Company obtain the requisite consents and approvals to amend the 2010 Notes and the Company’s other existing convertible debt to remove such conversion discount;  

WHEREAS, Ladenburg has also recommended that the Company change the structure of the IPO from a unit offering structure, as previously contemplated by Maxim, to a straight common stock offering structure;

WHEREAS, as a result of such recommendations, the Company seeks the consent of the Holders to (a) amend the 2010 Notes to remove the conversion discount at which the 2010 Notes will convert into equity securities in connection with the IPO and to modify the reference to a unit offering in the definition of “Qualified IPO”, (b) amend the Warrants to modify the reference to a unit offering in the definition of “Qualified IPO” and (c) amend the Purchase Agreements to provide for registration rights for shares of common stock issuable upon conversion of the Related Party Notes (as defined in the 2010 Notes, as amended hereby), in each case on the terms set forth herein, in order to maximize the Company’s ability to complete the IPO;

WHEREAS, each of the undersigned Holders agrees to amend the 2010 Notes, the Warrants and the Purchase Agreements on the terms set forth herein; and

WHEREAS, such amendments require the written consent of the Company and the holders of not less than sixty-six and two-thirds percent (66 ⅔%) of the aggregate outstanding principal amount of the 2010 Notes and the holders of not less than sixty-six and two-thirds percent (66 ⅔%) of the Warrant Shares (as defined in the Warrants) then issuable upon exercise of the Warrants (the “Requisite Approval”) pursuant to Section 6.2 of the Purchase Agreements, Section 11 of the Notes and Section 7 of the Warrants.
