Chapter 29 or other statutes, the Licensee may:

(a)

defend the suit in its own name, at its own expense, and on its own behalf for presumably valid claims in the Licensed Patent Rights;

(b)

in any suit, ultimately to enjoin infringement and to collect for its use, damages, profits, and awards of whatever nature recoverable for the infringement; and

(c)

settle any claim or suit for declaratory judgment involving the Licensed Patent Rights provided, however, that the NIH and appropriate Government authorities shall have the first right to take these actions and shall have a continuing right to intervene in the suit; and

(d)

If the NIH does not notify the Licensee of its intent to respond to the legal action within a reasonable time, the Licensee shall be free to do so. The Licensee shall take no action to compel the Government either to initiate or to join in any declaratory judgment action.

XXXXXXXX X — COMMERCIAL DEVELOPMENT PLAN

The IL4-PE fusion protein (MDNA55) is a novel protein comprised of circularly permuted interleukin-4 (IL-4) fused to an engineered version of Pseudomonas exotoxin (PE). The IL-4 portion of MDNA55 was designed so that the molecule can bind with a very high level of specificity to IL-4 receptors on the surface of cells. The Pseudomonas exotoxin portion of MDNA55 has been designed to minimize undesirable side effects by reducing its ability to bind non-specifically to cells containing the Pseudomonas exotoxin receptor while retaining its high potency.

Phase I and II studies were conducted using MDNA55 for recurrent glioblastoma multiforme (GBM) and peripheral solid tumors under a Sponsor-led IND. Licensee has acquired the regulatory assets, clinical data, and product related assets, and in-licensed all relevant non-HHS patents related to MDNA55. Licensee plans to conduct the following Development Plan for continued development of MDNA55 for localized treatment of CNS tumors, non-CNS tumors and urological diseases.

Commercial Development Plan:

Licensee plans to continue Phase 2b clinical development of MDNA55 as a monotherapy for the treatment of recurrent glioblastoma (rGB). It is expected that as additional clinical data are collected, the label claim may expand to include combination approaches with approved agents such as chemotherapy (Temodar) and/or bevacizumab. Thus, in addition to the ongoing study, Licensee plans to conduct pre-clinical studies evaluating the safety and efficacy of MDNA55 in combination with approved agents for rGB and potentially other agents not currently approved for rGB such as checkpoint inhibitors. Of particular significance may be the ability of MDNA55 to eliminate brain tumor stem cells and immunosuppressive cells of the glioma tumor microenvironment. Previous data has shown that MDNA55 is capable of inhibiting growth of IL-4R expressing spheroid cultures of chemo-surviving colon cancer stem cells as well as pancreatic cancer stem cells. Although similar studies have yet to be performed in brain tumor stem cells, it is possible that MDNA55 could selectively eliminate this resistant cell population resulting in the potential for enhanced sensitivity to other therapies administered in combination with MDNA55. Licensee plans to investigate potential synergistic effects of MDNA55 in combination with other therapeutic agents using in vitro and relevant animal models.

6) In the event any provision(s) of the Agreement is/are inconsistent with Attachment 1 such provision(s) is/are hereby amended to the extent required to avoid such inconsistency and to give effect to the payment information in such Attachment 1.
