The amended license agreement includes increased contingent milestone payments, now totaling up to $100 million, as well as increased royalties on sales.

“We are extremely pleased by Baxter’s commitment to Xenetic and to our longstanding collaboration to develop polysialylated blood coagulation factors using Xenetic’s unique technology,” said Scott Maguire, Chief Executive Officer of Xenetic. “The new terms in our agreement represent enhanced economics for Xenetic. Additionally, we expect to utilize the capital resulting from Baxter’s equity investment to further advance our development pipeline programs, particularly in the orphan drug arena, which feature a number of potential near-term, value-creating clinical milestones. This important new investment from our leading license partner is a genuinely dynamic development for the Company as we start our new life in the United States and it augurs well for our future in the world’s leading economy and pharmaceutical market.”

Brian Goff, head of Baxter’s hemophilia organization, commented, “Through our Xenetic partnership, we are seeking to identify and introducedevelop a treatment that mostthe majority of hemophilia patients could administer once weekly or less frequently, potentially at once weekly intervals, without compromising efficacy. Our investment in Xenetic reflects our continued commitment to the hemophilia community and to our pursuit of a bleed-free world.”


In August 2005, Xenetic and Baxter established an exclusive worldwide agreement to develop novel forms of polysialylated blood coagulation factors, including Factor VIII, using Xenetic technology to conjugate polysialic acid (PSA) to therapeutic blood-clotting factors. The goal of the program is to improve the pharmacokinetic profile and extend the active life of these factors, thereby improving upon existing therapies and increasing quality of life of patients.

BAXTER ANNOUNCES RESTRUCTURED AGREEMENT WITH XENETIC BIOSCIENCES, FURTHER BOLSTERING ITS BROAD BLEEDING DISORDER PIPELINE

DEERFIELD, III., JANUARY 29,30, 2014 Baxter International Inc. (NYSE:BAX) has restructured its ongoing agreement with Xenetic Biosciences, Inc. (OTCBB: GAIFD) for the development of BAX 826, a recombinant Factor VIII treatment for hemophilia A under investigation to assess its potential to extend the half-life and duration of effectiveness. This program complements the company’s current development programs, which are focused on improving the pharmacokinetic profile and extending the half-life of blood coagulation factors, including Factor VIII.

“Through our Xenetic partnership, we are seeking to identify and introducedevelop a treatment that the majority of hemophilia patients could administer once weekly or less frequently, potentially at once weekly intervals, without compromising efficacy,” said Brian Goff, head of Baxter’s global hemophilia organization. “We are focusing our efforts on using a range of


technologies to introduce new therapies and enhancements to existing therapies, each designed to improve the patient experience as we pursue our vision of a bleed-free world.”

Xenetic and Baxter previously established an exclusive worldwide agreement to develop novel forms of polysialylated blood coagulation factors, including Factor VIII, using Xenetic’s proprietary polysialic acid (PSA) technology. Under the terms of the restructured arrangement, Baxter will make a $10 millionan equity investment in the common stock of Xenetic and has agreed to make contingent milestone payments as well as pay royalties on future sales.

This agreement further demonstrates Baxter’s long-standing commitment to innovation in hemophilia, and bolsters the company’s broad R&D pipeline focused on a variety of challenging bleeding disorders. For example, Baxter recently announced the completion of enrollment in a Phase III clinical trial of BAX 855, its investigational, extended half-life, recombinant Factor VIII (rFVIII) treatment for hemophilia A. The company continues to expect to file for regulatory approval for BAX 855 in the United States by the end of 2014.

The company is also advancing a number of other treatments and early-stage R&D programs, including the study of BAX 335, an investigational Factor IX gene therapy treatment for hemophilia B. The vector-based technology, which provides a mechanism for the patient’s own liver to begin


producing Factor IX following a single dose of the genetically engineered treatment, has the potential to re-define the concept of longer-acting therapy. A Phase I/II open-label clinical trial to assess the safety and optimal dosing schedule of BAX 335 is underway and the first patients have been dosed.
