Net Sales by the number of units of such Other Component(s) sold during such Calendar Quarter). 

  
 13 













 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 I-MAB ’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 I-MAB or its Related Parties, during a Calendar Quarter in which such Combination Product is sold, the average Net Sales per unit sold in the
above described equation shall be replaced with I-MAB ’s and MacroGenics’ mutual agreement of the fair market value of the Licensed Component and each of the Other Component(s) included in such
Combination Product.

 (ii)    [***] shall have the initial right (but not the
obligation) to institute and direct legal proceedings against any Third Party believed to be infringing Jointly Owned Patents that claims or covers a Product sold [***]. MacroGenics agrees to discuss the foregoing in good faith with I-MAB as it pertains to the Product sold in the Territory. If [***] does not abate such violation of Jointly Owned Patents in the Territory, including by commencement of a lawsuit against the accused person if
necessary, [***] after receiving notice of such infringement of Jointly Owned Patents, then [***] shall be entitled (but shall not be obligated) to take all actions reasonably necessary to abate such violation in the Territory solely with respect to

 Exhibit H 

Form of Press Release 
 MacroGenics and
I-Mab Announce Exclusive Collaboration and License Agreement to Develop and Commercialize Enoblituzumab in Greater China 

ROCKVILLE, MD, and SHANGHAI, China, July 9, 2019 (GLOBE NEWSWIRE) – MacroGenics, Inc. (NASDAQ: 

MGNX), a clinical-stage biopharmaceutical company focused on discovering and developing innovative monoclonal antibody-based therapeutics for the treatment of
cancer, and I-Mab Biopharma (I-Mab), a China and U.S.-based clinical-stage biopharmaceutical company committed to the discovery and development of first-in-class and best-in-class biologics in immuno-oncology and autoimmune diseases,
announced today that the companies have entered into an exclusive collaboration and license agreement to develop and commercialize enoblituzumab. This investigational drug is an immune- optimized, anti-B7-H3 monoclonal antibody that incorporates MacroGenics’ proprietary Fc Optimization technology platform. Enoblituzumab represents one of the most advanced programs in development directed against B7-H3, a target for which no agent is currently approved. I-Mab obtains regional development and commercialization rights in mainland China, Hong Kong, Macau and Taiwan. 

As part of the collaboration, I-Mab will both lead regional studies in its territories as well as participate in
global studies conducted by MacroGenics. MacroGenics intends to initiate a Phase 2 study of enoblituzumab in combination with MGA012 (also known as INCMGA0012), an investigational
anti-PD-1 antibody that MacroGenics licensed to Incyte Corporation, in first-line patients with head and neck cancer later this year. 

“We are very pleased to be partnering with I-Mab to further accelerate and broaden the development of
enoblituzumab and to support our mission of bringing innovative medicines to patients with high unmet medical needs,” said Scott Koenig, M.D., Ph.D., President and Chief Executive Officer of MacroGenics. “We believe that I-Mab is an ideal partner given its track record of rapidly progressing innovative immuno-oncology programs and its ability to tap into the growing pharmaceutical market in this region.” 

“MacroGenics is recognized as a leader in the development of therapeutics targeting B7-H3 and we are committed to
accelerating the development of enoblituzumab, a promising investigational drug which may represent a new treatment paradigm in immuno-oncology,” said Jingwu Zang, M.D., Ph.D., Chief Executive Officer of
I-Mab. “We believe that this program is an exciting addition to our innovative pipeline of clinical stage oncology assets.” 

MacroGenics expects to receive an upfront payment of $15 million in connection with the collaboration. MacroGenics will also be eligible to receive
additional development and regulatory milestone payments of up to $135 million. In addition, I-Mab will pay tiered double-digit royalties (ranging from mid teens to twenty percent) based on annual net
sales in its territories. 












 About Enoblituzumab Program 

Enoblituzumab is an investigational Fc-optimized monoclonal antibody that targets
B7-H3, a member of the B7 family of immune regulator proteins. B7-H3 is widely expressed by a number of different tumor types and may play a key role in regulating the
immune response to various types of cancer. 
 Encouraging data from the Phase 1 clinical study of enoblituzumab in combination with an anti-PD-1 antibody were presented at the Society for Immunotherapy of Cancer (SITC) Annual Meeting in November 2018. Based on these data, MacroGenics is planning to initiate a
Phase 2 study of enoblituzumab in combination with MGA012 in patients with squamous cell carcinoma of the head and neck (SCCHN) in the second half of 2019. 

About MacroGenics’ Fc-Optimization Technology 

MacroGenics’ Fc-Optimization platform is designed to modulate an antibody’s interaction with immune effector
cells. The Fc region of certain antibodies binds activating and inhibitory receptors, referred to as FcgRs, on immune cells found within the innate immune system. Such interactions affect killing of
cancer cells through antibody dependent cellular cytotoxicity (ADCC), among other Fc-dependent functions. 

MacroGenics’ optimized Fc region binds with increased affinity to the activating CD16A FcgR and unique to
MacroGenics’ technology, with reduced affinity to CD32B, the inhibitory FcgR. MacroGenics’ optimized Fc mediates improved effector functions, such as ADCC. To date, MacroGenics has successfully
incorporated its proprietary Fc Optimization technology in enoblituzumab, as well as margetuximab, an investigational anti-HER2 monoclonal antibody currently in Phase 3 development.
