existing licensing deal with Baxter. 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

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. 
 About Baxter in Hemophilia 

Baxter has more than 60 years experience in hemophilia and has introduced a number of therapeutic firsts for hemophilia patients. Baxter has
the broadest portfolio of hemophilia treatments in the industry and is able to meet individual therapy choices, providing a range of options at each treatment stage. The company’s work focuses on optimizing hemophilia care and improving the

 This release includes forward-looking statements concerning developments to Baxter’s R&D pipeline,
including the development agreement between Baxter International Inc. and Xenetic Biosciences, Inc. Such statements include expectations with regard to clinical trials, regulatory filings, the impact of new treatments to patients, and potential
payments under the development agreement. The statements are based on assumptions about many important factors, including the following, which could cause actual results to differ materially from those in the forward-looking statements: satisfaction
of regulatory and other requirements; actions of regulatory bodies and other governmental authorities; clinical trial results; changes in laws and regulations; product quality or patient safety issues; and other risks identified in Baxter’s
most recent filings on Form 10-K and other SEC filings, all of which are available on Baxter’s website. Baxter does not undertake to update its forward-looking statements.
