License and Collaboration Agreement

On December 19, 2017 (the “Effective Date”), Zai Lab (Shanghai) Co., Ltd. (“Zai”) entered into a License and Collaboration Agreement (the “Agreement”) with Five Prime Therapeutics, Inc. (“FivePrime”), pursuant to which FivePrime granted Zai exclusive rights to develop and commercialize FivePrime’s proprietary afucosylated FGFR2b antibody known as FPA144, and all fragments, conjugates, derivatives and modifications thereof (the “Licensed Antibody”) in China, Hong Kong, Macau and Taiwan (each, a “region,” and collectively, the “Territory”).

Under the terms of the Agreement, Zai will be responsible, at its expense, for (i) developing and commercializing products containing the Licensed Antibody (each, a “Licensed Product”) under a territory development plan (ii) performing certain development activities to support FivePrime’s global development and registration of Licensed Prodcuts, including FivePrime’s global Phase 3 registrational trial of FPA144 in combination with FOLFOX in front-line gastric and gastroesophageal cancer (the “FPA144-004 Study”) in the Territory under a global development plan.

Pursuant to the Agreement, Zai will make an upfront payment of $5 million to FivePrime. Additionally, with respect to each Licensed Product, FivePrime will be eligible to receive up to $39 million in specified developmental and regulatory milestone payments.

Zai will also be obligated to pay FivePrime a royalty, on a Licensed Product-by-Licensed Product and region-by-region basis, in the high teens or low twenties, depending on the number of patients Zai enrolls in the FPA144-004 Study, subject to reduction in certain circumstances, on net sales of each Licensed Product in the Territory until the latest of (i) the 11th anniversary of the first commercial sale of such Licensed Product in such region, (ii) the expiration of certain patents covering such Licensed Product in such region, and (iii) the date on which any applicable regulatory, pediatric, orphan drug or data exclusivity with respect to such Licensed Product expires in such region.

Under the Agreement, provided that Zai enrolls and treats a specified number of patients in the FPA144-004 Study in China, Zai is eligible to receive a low single-digit percentage royalty, on a Licensed Product-by-Licensed Product basis on net sales of a Licensed Product outside the Territory until the 10th anniversary of the first commercial sale of each such Licensed Product outside the Territory.

Unless earlier terminated by either party, the Agreement will expire on a Licensed Product-by-Licensed Product and region-by-region basis upon the expiration of Zai’s payment obligations with respect to each Licensed Product under the Agreement. Zai may terminate the Agreement in its entirety at any time with advance written notice. Either party may terminate the Agreement in its entirety with written notice for the other party’s material breach if such party fails to cure the breach. FivePrime may terminate the Agreement in its entirety with written notice for Zai’s material breach of its diligence obligations with respect to development and obtaining marketing approval, and may terminate the agreement on a region-by-region basis for Zai’s breach of its diligence obligations with respect to timely commercialization of a Licensed Product in a region following marketing approval. FivePrime may terminate the agreement in its entirety if Zai or its affiliates or sublicensees commences a legal action challenging the validity, enforceability or scope of any of FivePrime’s patents in the Territory. Either party also may terminate the Agreement in its entirety upon certain insolvency events involving the other party.

The foregoing description of the Agreement is only a summary and is qualified in its entirety by reference to the Agreement, a copy of which will be filed as an exhibit to Zai’s Annual Report on Form 20-F for the fiscal year ending December 31, 2017.

Five Prime Therapeutics and Zai Lab Announce Exclusive License Agreement for FPA144 Anti-FGFR2b Antibody in Greater China and Global Strategic Development Collaboration

Planned global Phase 3 FIGHT trial in front-line gastric and gastro-esophageal junction cancers to include sites in China where disease incidence is the highest in the world

SOUTH SAN FRANCISCO, Calif. and SHANGHAI, China, Dec. 19, 2017 — Five Prime Therapeutics, Inc. (NASDAQ: FPRX), a biotechnology company discovering and developing innovative immuno-oncology protein therapeutics, and Zai Lab Limited (NASDAQ: ZLAB), a Shanghai-based innovative biopharmaceutical company, today announced an exclusive license agreement for FPA144 in Greater China and global strategic development collaboration. Five Prime’s FPA144 is a first-in-class isoform-selective, humanized monoclonal antibody in clinical development as a targeted immuno-therapy for tumors that overexpress FGFR2b, including gastric and gastro-esophageal junction cancer. China has one of the highest incidence rates of gastric cancer in the world, with approximately 680,000 new cases annually.1,2 The randomized, controlled Phase 3 portion of the FIGHT trial evaluating FPA144 plus chemotherapy is expected to start in the second half of 2018 and would serve as a global registrational study for the treatment of front-line gastric and gastro-esophageal junction cancers. Zai Lab will manage the Phase 3 portion of the trial in China.

“We believe Zai Lab is the right partner for FPA144 in Greater China for this innovative product,” said Aron Knickerbocker, Chief Operating Officer of Five Prime and incoming Chief Executive Officer (effective January 1, 2018). “China accounts for more than 40% of new gastric cancer cases globally2, so it is critical to align strategically with a strong collaborator with the infrastructure, relationships and resources to help us advance FPA144 global development expeditiously. Zai Lab is ideally positioned given their experienced leadership team, focus on innovative drugs, and established expertise and network within oncology. We look forward to working with Zai Lab to carry out our worldwide development program for FPA144 and accelerate enrollment in the global Phase 3 portion of the FIGHT trial.”

“Five Prime has pioneered the development of some very exciting and highly-targeted antibodies, including FPA144, which we believe holds tremendous promise for cancer patients in Greater China. We are committed to working with Five Prime to accelerate the global development timelines for this important investigational therapy,” stated Samantha Du, Chairman and CEO of Zai Lab. “This strategic collaboration highlights the strength of our team and business model as the partner of choice in China and in delivering innovative therapies to patients in China and beyond.”

Under the terms of the agreement, Five Prime has granted Zai Lab an exclusive license to develop and commercialize FPA144 in the Greater China territory: China, Hong Kong, Macau, and Taiwan. Zai Lab will be responsible for conducting the Phase 3 FIGHT trial in Greater China, including screening, enrollment and treatment of patients, and for commercialization of


FPA144 in the Greater China territory. Five Prime will manufacture and supply FPA144 for the study. A Joint Steering Committee will be formed between the companies to oversee development, regulatory and commercialization activities in greater China. Five Prime will receive a $5 million upfront payment and is eligible to receive up to $39 million in development and regulatory milestone payments. Five Prime is also eligible to receive from Zai Lab a royalty percentage on net sales of FPA144 in Greater China ranging from the high teens to the low twenties. Given the strategic importance of China to the development and commercialization of FPA144 and to align the interests of the two companies globally, Zai Lab is also eligible to receive a low single-digit royalty from Five Prime on net sales of FPA144 outside of Greater China.

“Gastric cancer is the fifth most common cancer in the world and the second most common in China. Patients whose tumors overexpress FGFR2b or have FGFR2 gene amplification have an especially poor prognosis,” said Dr. Shukui Qin, the Executive Member of the Asian Clinical Oncology Society, Senior Vice President of Chinese Society of Clinical Oncology and the Director of Cancer Center of People’s Liberation Army. “I am encouraged that we may be able to identify those patients with companion diagnostics and potentially treat them more effectively with a highly targeted therapy like FPA144. There is a critical need for more effective and safe therapies for gastric cancer patients here, so I am pleased that I and my fellow oncologists throughout China can play an important role in the FIGHT trial.”

About FPA144

FPA144 is an isoform-selective, humanized monoclonal antibody in clinical development as a targeted immuno-therapy for tumors that overexpress FGFR2b, a splice variant of a receptor for some members of the fibroblast growth factor (FGF) family. FPA144 has also been engineered for enhanced antibody-dependent cell-mediated cytotoxicity (ADCC) to increase direct tumor cell killing by recruiting natural killer (NK) cells.

FPA144 is being evaluated as a potential treatment for gastric cancer and bladder cancer. In a Phase 1 trial, FPA144 demonstrated monotherapy activity in heavily pre-treated patients with FGFR2b-positive gastric cancer and did not exhibit certain toxicities that have been seen with less selective FGFR2 small molecule therapeutics. An estimated 10% patients with gastric cancer have tumors that overexpress FGFR2b or have FGFR2 gene amplification, which is associated with poor prognosis.
