 [    *    ] Confidential Treatment Requested










 
applicable royalty reporting periods for the entire calendar year. When determining the average sale price or inventory cost of a Product or Other Active
Agents, data for the preceding calendar year shall be used for calculating the applicable fraction; provided, however, that with respect to the first year of RoW Net Sales of a Combination Product for a country when there have not been prior
separate sales of the corresponding Product, a reasonable estimate of the applicable fraction shall be used, and an adjustment made after the end of the year for the actual fraction calculated for the year. As used above, the term “Combination
Product” means any pharmaceutical product which is comprises a Product and other pharmaceutically active compounds which are not moieties that are the subject of third-party patents pursuant to which royalties are payable to such third-parties
in association with any Patent Products commercialized in accordance with this Agreement (“Other Active Agents”). 
 Notwithstanding
the foregoing, the RoW Net Sales of a Product in a country shall never be reduced below [    *    ] of the gross amount invoiced for the Combination Product. 
 Any Product sold or otherwise disposed of in other than an arm’s-length transaction or for other property (e.g., barter) shall be deemed invoiced at its fair
market value in the country of sale or disposition. 
 SECTION 1.54. “RoW Net Sales Milestones” means: the net cumulative dollar amount
(i.e., after subtracting payments or other reductions creditable to such milestones pursuant to the applicable agreement) received by ZGEN from a third party Commercialization Partner for milestones based upon RoW Net Sales of a Product that would
exceed a designated dollar amount resulting in a Commercialization Partner being obligated pay to ZGEN a one time fee. For the avoidance of doubt, RoW Net Sales Milestones do not include royalty payments received by ZGEN pursuant to SECTION 5.1 or
RoW Net Development Milestones. 
 SECTION 1.55. “Second Restated License Agreement” means the Second Restated License Agreement for IL-21
effective as of January 16, 2009 between ZGEN and NN.

 (a) if
such legal action shall have been initiated or conducted by ZGEN: (i) unless NN voluntarily joins such suit, or has been required to be joined as a party (but has not at its own expense joined such legal proceeding initiated by ZGEN), ZGEN
shall have the right to retain [    *    ]; or (ii) if NN has voluntarily joined such suit or has been required to be joined as a party (and has at its own expense joined such legal proceeding initiated
by ZGEN), both NN and ZGEN shall be reimbursed for their respective internal and external expenses (including reasonable attorneys’ fees and costs) incurred in the legal action; and, second, the remaining balance from such recovery shall be

attorneys’ fees) or liability of any kind arising out of personal injury or property damage caused or alleged to be caused as a result of Ongoing Clinical Trials. NN’s indemnification obligations under this SECTION 7.2 will arise only if
ZGEN (i) notifies NN promptly after it becomes aware of a Claim; (ii) permits NN to control the defense and settlement, at NN’s expense, of any such Claim; and (iii) does not settle any such Claim without the prior written
approval and consent of NN, which consent shall not be unreasonably withheld. If such a Claim is brought, ZGEN shall render, at NN’s cost and expense, all reasonable assistance requested by NN in defending such Claim. NN’s obligations
under this SECTION 7.2 shall not apply to the extent that the Claim arose from the gross negligence or willful misconduct of ZGEN (or its directors, officers, employees or agents). 
 SECTION 7.3. Insurance. ZGEN shall maintain and cause its Affiliates, Commercialization Partners and Sublicensees to maintain, to the extent possible, appropriate product liability insurance with respect to the
development, manufacture and sale of Products in RoW in such amount as each party customarily maintains with respect to sales of its other RoW products. ZGEN shall maintain and cause its Affiliates, Commercialization Partners and sublicensees to
maintain, to the extent possible, such insurance for so long as it continues to manufacture or sell Products in RoW and thereafter for so long as each party customarily maintains insurance with respect to sales of its other RoW products.

 ARTICLE 8  
 Term and Termination 
 SECTION 8.1. Term and Expiration. This Agreement shall become effective on the
Effective Date. Unless terminated earlier, the licenses provided hereunder for any Products shall expire on the date of expiry of the last to expire of the Licensed Patents, and this Agreement shall expire on the later of the (i) date of expiry
of the last to expire of the Licensed Patents, (ii) date of expiry of the last to expire of the IL-21 ZGEN Patent Rights or (iii) date on which NN is no longer entitled to receive a royalty from ZGEN on any Product under this Agreement.
After expiration (but not termination) of this Agreement, ZGEN shall have a fully paid up, irrevocable, non-exclusive license under the Licensed Know-How to make, have made, use, sell and have sold Products worldwide. 
 SECTION 8.2. Non-Viability. ZGEN may terminate this Agreement upon six (6) months prior written notice to NN with an explanation contained therein if, in the
reasonable opinion of ZGEN’s senior management, the commercialization of IL-21 Protein or Products must be terminated for safety or efficacy reasons or lack of commercial viability. Termination pursuant to this SECTION 8.2 by ZGEN shall
automatically terminate the licenses that NN granted to ZGEN under SECTION 3.2. 
 SECTION 8.3. Termination for Insolvency. Each party shall have the
right to terminate this Agreement: (a) if the other party is declared insolvent or bankrupt by a court of competent jurisdiction; (b) if a voluntary or involuntary petition in bankruptcy is filed in any court of competent jurisdiction
against the other party and such petition remains undismissed, undischarged or unbonded for a period of ninety (90) days after the filing thereof; or (c) if the other party shall make or execute an assignment for the benefit of creditors
generally, have a receiver, administrator or an equivalent official appointed with respect to its properties or undertakings, enter into any liquidation or become insolvent. Termination pursuant to this SECTION 8.3 by NN shall automatically
terminate the licenses that NN granted to ZGEN under SECTION 3.2. Notwithstanding the above, termination pursuant to this SECTION 8.3 by ZGEN shall not terminate the licenses that NN granted to ZGEN under SECTION 3.2. 
 SECTION 8.4. Termination for Material Breach. If a party (the “Breaching Party”) is in material breach of its obligations under this
Agreement (including failure to meet diligence, or reporting obligations or failure to pay amounts due), the other party (the “Non-Breaching Party”) shall have the right to terminate this Agreement upon written notice to the
Breaching Party, which notice shall include an explanation specifying the material breach. If the Breaching Party has not cured such material breach within sixty (60) days after the date of such written notice (or ten (10) days in the case
of the failure to pay any amount due), this Agreement shall terminate upon expiration of such sixty (60) day, or ten (10) day, period, as applicable. Termination pursuant to this SECTION 8.4 by NN shall automatically terminate the licenses
that NN granted to ZGEN under SECTION 3.2. 
 SECTION 8.5. Effect of Expiration or Termination. Except as expressly stated herein, expiration or
termination of this Agreement shall not relieve the parties of any obligations accruing prior to such expiration or termination, including any payment obligations, and the

obligation to provide data, information and documentation generated prior to the date of termination and to deliver reports incorporating such
information and documentation. In addition to any provision that expressly provides for its survival, the provisions of ARTICLES 1, 3 (as modified by this ARTICLE 8), 6, 7 and 10 and SECTIONS 4.7, 5.4, 5.6, 8.6, 9.3 and 9.4 shall survive the
expiration or termination of this Agreement. Expiration or termination of this Agreement shall not affect any party’s ability to seek any other remedies available at law. 
 SECTION 8.6. Return of Technical Information. Upon termination of this Agreement, unless such termination is due to a material breach of this Agreement by NN under SECTION 8.4 or due to the insolvency of NN
under SECTION 8.3, ZGEN shall, upon NN’s request, cause to be promptly delivered to NN all RoW materials containing any Licensed Know-How and any other RoW documents, data or Confidential Information relating to the IL-21 Protein solely in RoW
obtained from NN by ZGEN pursuant to this Agreement and shall (a) at NN’s election, assign to NN all rights in any RoW pre-clinical and/or clinical data, RoW clinical trial protocols, RoW regulatory applications or approvals (e.g.,
INDs) (to the extent assignable) requested by NN, and cause each of its Affiliates, Commercialization Partners and Sublicensees to take such actions as to which NN shall be responsible for all future costs and charges accruing thereunder, and
(b) during the six (6) months following termination, discuss with NN RoW information and data that exists with respect to the IL-21 Protein and Products and provide to NN such relevant information and data requested by NN, which it may
thereafter use, either alone or with others.
