Such amounts shall be determined from the books and records of Zai or its Related Party, maintained in accordance with Zai’s Accounting Standards, as consistently applied. Zai further agrees, in determining such amounts, it shall use Zai’s then-current standard procedures and methodology, including Zai ’s then-current standard exchange rate methodology for the translation of foreign currency sales into US Dollars or, in the case of Sublicensees, such similar methodology, consistently applied. Without limiting the generality of the foregoing, non-invoiced transfers or dispositions of Product for charitable, compassionate use, promotional (including samples, in amounts reasonably customary in the industry), non-clinical, clinical, or regulatory purposes shall be excluded from Net Sales, as will sales or transfers of Product among a Party and its Related Parties, unless such Party or Related Party is the end user of such Product, but rather the Net Sales shall be deemed to have arisen upon the subsequent sale or transfer of Product to Third Parties.

If Zai or any of its Related Parties sells a Product as a Licensed Component of a Combination Product in a country or Region in any Calendar Quarter, then Net Sales shall be calculated by multiplying the Net Sales of the Combination Product during such Calendar Quarter by the fraction A/(A+B), where

A is the average Net Sales per unit sold of the Licensed Component when sold separately in such country or

Region during such Calendar Quarter (calculated by determining the Net Sales of the Licensed Component during such Calendar Quarter in accordance with the definition of Net Sales set forth herein and dividing such Net Sales by the number of units of the Licensed Component during such Calendar Quarter) and B is the average Net Sales per unit sold of the Other Component(s) included in the Combination Product when sold separately in such country or Region during such Calendar Quarter (calculated by determining the Net Sales of such Other Component(s) sold during such Calendar Quarter by applying the definition of Net Sales set forth herein as if it applied to sales of such Other Component(s) and dividing such Net Sales by the number of units of such Other Component(s) sold during such Calendar Quarter).

For purposes of calculating the average Net Sales per unit sold of a Licensed Component and Other Component(s) of a Combination Product, any of the deductions described herein that apply to such Combination Product shall be allocated among sales of the Licensed Component and sales of the Other Component(s) included in such Combination Product as follows: (i) deductions that are attributable solely to the Licensed Component or one of the Other Component(s) shall be allocated solely to Net Sales of the Licensed Component or such Other Component, as applicable, and (ii) all other deductions shall be allocated among sales of the Licensed Component and sales of the Other Component(s) in proportion to Zai’s and MacroGenics’ mutual agreement of the fair market value of the Licensed Component and the Other Component(s).

In the event that no separate sales of the Licensed Component or any Other Component(s) included in a Combination Product are made by Zai or its Related Parties, during a Calendar Quarter in which such Combination Product is sold, the average Net Sales per unit sold shall be determined by mutual agreement of the Parties in good faith based on the relative economic value contributions of the Licensed Component and each of the Other Component(s) included in such Combination Product.

–Zai Lab granted combination of regional Asian and global rights for up to four CD3- or CD47-based bispecific molecules

–MacroGenics provides rights to Zai Lab for its DART® and TRIDENT® multi- specific platforms and a lead research program targeting solid tumors

–Zai Lab provides rights to MacroGenics for certain intellectual property related to CD47 for select tumor targets

SHANGHAI, SAN FRANCISCO and ROCKVILLE, MD, June 16, 2021 (GLOBE

NEWSWIRE) – Zai Lab Limited (NASDAQ: ZLAB; HKEX: 9688), an innovative commercial-stage biopharmaceutical company, and MacroGenics (NASDAQ: MGNX), a biopharmaceutical company focused on developing and commercializing innovative monoclonal-antibody-based therapeutics for the treatment of cancer, announced today that the companies have entered into an exclusive collaboration and license agreement involving up to four immuno-oncology molecules.

The first collaboration program covers a lead research molecule that incorporates MacroGenics’ DART platform and binds CD3 and an undisclosed target that is expressed in multiple solid tumors. The next-generation CD3 component of the DART bispecific molecule has been designed to minimize cytokine-release syndrome while maintaining anti-tumor cytolytic activity. The second collaboration program will cover a target to be designated by MacroGenics. For both molecules, Zai receives commercial rights in Greater China, Japan, and Korea and MacroGenics receives commercial rights in all other territories. For the lead molecule, Zai Lab receives an option upon reaching a predefined clinical milestone to convert the regional arrangement into a global 50/50 profit share.

Zai Lab also obtains exclusive, global licenses from MacroGenics to develop, manufacture and commercialize two additional molecules. For the four programs, each company will contribute intellectual property to generate either CD3- or CD47-based bispecific antibodies.

“We are very pleased to be expanding our existing relationship with Zai Lab, which already includes regional rights in Greater China for two clinical-stage programs,” said Xxxxx Xxxxxx, M.D., Ph.D., President and Chief Executive Officer of MacroGenics. “Zai has a strong track record of rapidly progressing the development of innovative product candidates in China. This new partnership enables us to jointly discover, develop and deliver potentially best-in-class therapeutics to address patients’ unmet medical needs.”

“MacroGenics has been a great partner and one of the leading companies in the immuno- oncology field,” said Samantha Du, Ph.D., Founder, Chairperson, Chief Executive Officer of Zai Lab. “We are pleased to expand our strategic collaboration, which leverages both companies’ unique research capabilities and gives Zai Lab access to MacroGenics’ proprietary technologies to expand our innovative oncology portfolio on a global basis.”

Under the terms of the agreement, MacroGenics receives initial consideration from Zai Lab of $55 million, including an upfront payment of $25 million and an equity investment of $30 million in MacroGenics’ common stock at $31.30 per share. In addition, MacroGenics is eligible to receive up to $1.4 billion in potential development, regulatory and commercial milestone payments for the four programs. If products from the collaboration are commercialized, MacroGenics would also receive royalties on annual net sales in Zai Lab’s territories.
