(a)    Everest’s share of the Product Profit/Loss shall equal Everest Total Cost / (Everest Total Cost + I-Mab Total Cost) – 5%, and I-Mab’s share of the Product Profit/Loss shall equal I-Mab Total Cost / (Everest Total Cost + I-Mab Total Cost) + 5%, where 
 (i)    “Everest Total Cost”
is the sum of (A) total Development Cost actually incurred by Everest under Section 4.1 (either paid or shared, but excluding payment for cost overrun under Section 4.1(c)), and (B) Everest’s share of payments to MorphoSys
under Section 4.2, and 
 (ii)    “I-Mab Total
Cost” is the sum of (A) total Development Cost actually incurred by I-Mab under Section 4.1 (either paid or shared, and inclusive of payment for cost overrun under Section 4.1), and (B) I-Mab’s share of payments to MorphoSys under Section 4.2. 
 By way of example, if the Everest Total
Cost is $60 million and I-Mab Total Cost is $40 million, then Everest’s share of Product Profit/Loss shall equal $60M/($60M+40M) – 5% = 55%, and
I-Mab’s share of Product Profit/Loss shall equal $40M/($60M+40M) + 5% = 45%. For clarity, if I-Mab’s final decision regarding the Development of the CD38
Product increases the Development Budget and Everest elects to opt-out such budget increase as set forth in Section 2.4(b), then one hundred percent (100%) of the increase in Development Cost paid by I-Mab shall be included in I-Mab Development Cost and not in Everest Development Cost. 












 (b)    Within thirty (30) days after the end of each
calendar quarter in which the Commercialization Party has conducted Commercialization activities for the CD38 Product under the Commercialization Plan, the Commercialization Party shall submit to the other Party a reasonably detailed calculation of
the Product Profit/Loss for such calendar quarter, including the Net Sales of the CD38 Product and the Commercialization Costs incurred by or on account of the Commercialization Party to Commercialize the CD38 Product in such calendar quarter. 

(c)    If a Product Profit was realized for such calendar quarter, then the Commercialization Party shall pay to
the other Party its share (as calculated in accordance with subsection (a) above) of the Product Profit for such calendar quarter within thirty (30) days after the delivery of the Product Profit/Loss report. 

(d)    If a Product Loss was incurred for such calendar quarter, then the other Party shall pay to the
Commercialization Party its share (as calculated in accordance with subsection (a) above) of the Product Loss for such calendar quarter within thirty (30) days after the receipt of the Product Profit/Loss report. 

4.5    Out-license Income Sharing. The Parties shall share all Out-license Income from the out-license of the CD38 Product in the Field in the Territory (in the same ratio as Product Profit/Loss sharing) as follows: I-Mab shall promptly notify Everest after the receipt of any Out-license Income, shall first apply the Out-license Income to reimburse
each Party the reasonable cost and expenses (including internal cost) incurred by such Party and its Affiliates for the negotiation and execution of the out-license agreement, and then shall pay to Everest
Everest’s share (as calculated in accordance with Section 4.4(a)) of the remaining Out-license Income within thirty (30) days after receipt of the
Out-license Income by I-Mab. 

4.6    Currency; Exchange Rate. All payments to be made under this Agreement shall be made in US Dollars by
bank wire transfer in immediately available funds to a bank account designated by written notice from the receiving Party. The rate of exchange to be used in computing the amount of currency equivalent in US Dollars shall be made at the average of
the closing exchange rates reported in The Wall Street Journal (U.S., Eastern Edition) on the due date of the payment. 

4.7    Late Payments. If a Party does not receive payment of any sum due to it on or before the due date
therefor, simple interest shall thereafter accrue on the sum due to such Party from the due date until the date of payment at a per-annum rate of prime reported in The Wall Street Journal (U.S., Eastern
Edition) on the due date of the payment plus two percentage point or the maximum rate allowable by applicable law, whichever is less. 
  

	 	4.8	 Financial Records; Audit. 



(a)    [Intentionally left blank] 

(b)    Within sixty (60) days after the end of each calendar year, each Party shall allow an independent
certified public accountant jointly selected by the Parties to audit its records for such calendar year to verify the accuracy of the financial report furnished by such Party and any amounts to be shared or paid under this Agreement for such
calendar year. The cost of such annual audit shall be shared by the Parties (25% I-Mab: 75% Everest). 












 (c)    Any amounts shown to be owed but unpaid, or overpaid and
in need of refund, shall be paid or refunded (as the case may be) within thirty (30) days after the accountant’s report, plus interest (as set forth in Section 4.7) from the original due date. 

 

	 	4.9	 Tax. 



(a)    Taxes on Income. Each Party shall be solely responsible for the payment of all taxes imposed on its
share of income arising directly or indirectly from the collaborative efforts of the Parties under this Agreement. 

(b)    Tax Cooperation. The Parties agree to cooperate with one another and use reasonable efforts to avoid
or reduce tax withholding or similar obligations in respect of any payments made by a Party to the other Party under this Agreement. 

(c)    Payment of Tax. To the extent a Party is required by applicable law to deduct and withhold taxes on
any payment to the other Party, the paying Party shall pay the amounts of such taxes to the proper tax authority in a timely manner and promptly transmit to the other Party an official tax certificate or other evidence of such withholding sufficient
to enable such other Party to claim such payment of taxes.

 ARTICLE 6 

INDEMNIFICATION; LIMITATION OF LIABILITY 

6.1    Indemnification by Everest. Everest hereby agrees to defend, hold harmless and indemnify I-Mab, its Affiliates and their agents, directors, officers and employees (the “I-Mab Indemnitees”) from and against any and all liabilities, expenses and/or
losses, including without limitation reasonable legal expenses and attorneys’ fees (collectively “Losses”) in each case resulting from Third Party suits, claims, actions and demands (each, a “Third Party
Claim”) arising directly or indirectly out of (a) a breach of any of Everest’s obligations under this Agreement, or (b) the negligence or willful misconduct of any Everest Indemnitee. Everest’s obligation to indemnify
the I-Mab Indemnitees pursuant to the foregoing sentence shall not apply to the extent that any such Losses arise from any activities set forth in Section 6.2 for which
I-Mab is obligated to indemnify Everest Indemnitees under Section 6.2. 

6.2    Indemnification by I-Mab.
I-Mab hereby agrees to defend, hold harmless and indemnify Everest, its Affiliates and their agents, directors, officers and employees (the “Everest Indemnitees”) from and against any and all
Losses resulting from Third Party Claims arising directly or indirectly out of (a) a breach of any of I-Mab’s obligations under this Agreement; (b) the negligence or willful misconduct of I-Mab Indemnitees. I-Mab’s obligation to indemnify the Everest Indemnitees pursuant to the foregoing sentence shall not apply to the extent that any such Losses arise
from any activities set forth in Section 6.1, for which Everest is obligated to indemnify I-Mab Indemnitees under Section 6.1. 

6.3    Procedure. The indemnified Party shall provide the indemnifying Party with prompt notice of the claim
giving rise to the indemnification obligation pursuant to this Article 6 and the exclusive ability to defend (with the reasonable cooperation of the indemnified Party) or settle any such claim; provided, however, that the indemnifying Party
shall not enter into any settlement for damages other than monetary damages without the indemnified Party’s written consent, such consent not to be unreasonably withheld. The indemnified Party shall have the right to participate, at its own
expense and with counsel of its choice, in the defense of any claim or suit that has been assumed by the indemnifying Party. If the Parties cannot agree as to the application of Sections 6.1 and 6.2 to any particular Third Party Claim, the Parties
may conduct separate defenses of such Third Party Claim. Each Party reserves the right to claim indemnity from the other in accordance with Sections 6.1 and 6.2 above upon resolution of the underlying claim, notwithstanding the provisions of this
Section 6.3 requiring the indemnified Party to tender to the indemnifying Party the exclusive ability to defend such claim or suit. 

6.4    Shared Product Damages. The Parties shall share all Shared Product Damages as follows: If the Shared
Product Damage arises from the Development of the CD38 Product, including clinical trials, the Parties shall share such Shared Product Damage as Development Cost (i.e., 25% I-Mab : 75% Everest). If the Shared
Product Damage arises from the Commercialization of the CD38 Product, the Parties shall share such Shared Product Damage as Commercialization Cost (as calculated in accordance with Section 4.). If either Party receives notice of a Third Party
claim that arises from or is based on the Development, manufacture and/or Commercialization of the CD38 Product in the Field in the Territory, such Party shall inform the other Party in writing as soon as reasonably practicable, and the Parties
shall discuss a strategy on how to defend against such Third Party claim. 












 6.5    Limitation of Liability. NEITHER PARTY SHALL BE
LIABLE TO THE OTHER FOR ANY SPECIAL, INCIDENTAL, PUNITIVE, OR INDIRECT DAMAGES OR LOSS OF PROFITS ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING,
NOTHING IN THIS SECTION 6.5 IS INTENDED TO OR SHALL LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER SECTION 6.1 OR 6.2, THE OBLIGATION OF ANY PARTY TO SHARE THE SHARED PRODUCT DAMAGES, OR DAMAGES AVAILABLE FOR A
PARTY’S BREACH OF CONFIDENTIALITY OBLIGATIONS IN ARTICLE 7.

(d)    is subsequently disclosed to the receiving Party by a Third Party who has a legal right to make such
disclosure; or 
 (e)    is subsequently independently discovered or developed by the receiving Party without the

7.2    Authorized Disclosure. Notwithstanding the obligations set forth in Section 7.1, a Party may
disclose the other Party’s Confidential Information and the terms of this Agreement to the extent: 

(a)    such disclosure is reasonably necessary for (i) the Development, manufacture and/or
Commercialization of the CD38 Product, including obtaining and maintaining Regulatory Approval; or (ii) the prosecuting or defending litigation as contemplated by this Agreement; or 












 (b)    such disclosure is reasonably necessary: (i) to such

collaboration; provided that in each such case on the condition that such disclosures are bound by confidentiality and non-use obligations consistent with those contained in the Agreement; 

(c)    such disclosure is required by applicable Laws, including judicial or administrative process, provided that
in such event such Party shall promptly inform the other Party such required disclosure and provide the other Party an opportunity to challenge or limit the disclosure obligations. Confidential Information that is disclosed under this

subject matter, without the prior express written permission of the other Party, except as may be required by Law. 

7.4    Equitable Relief. Each Party acknowledges that a breach of this Article 7 cannot be reasonably or
adequately compensated in damages in an action at law and that such a breach shall cause the other Party irreparable injury and damage. By reason thereof, each Party agrees that the other Party shall be entitled, in addition to any other remedies it
may have under this Agreement or otherwise, to preliminary and permanent injunctive and other equitable relief to prevent or curtail any breach of the obligations relating to Confidential Information set forth herein. 

ARTICLE 8 
 TERM AND
TERMINATION 
 8.1    Term. This Agreement shall become effective on the Effective Date and, unless
earlier terminated pursuant to this Article 8, shall remain in effect until the Parties cease Development and Commercialization of the CD38 Product in the Field in the Territory (the “Term”). 












 8.2    Termination for Breach. Each Party shall have the
right to terminate this Agreement in its entirety immediately upon written notice to the other Party, if the other Party materially breaches its obligations under this Agreement that would (x) lead or cause
I-Mab to materially breaches its obligations under the MorphoSys Agreement or (y) lead or cause the essential business purpose of this Agreement could not be acheived and, after receiving written notice
identifying such material breach in reasonable detail, fails to cure such material breach within sixty (60) days from the date of such notice. For the avoidance of doubt, such material breach includes at least the following: on the part of I-Mab, I-Mab’s failure to make any payments due or use Commercially Reasonable Efforts to develop the CD38 Product under the MorphoSys Agreement; on the part of Everest,
Everest’s failure to make any payments due or use Commercially Reasonable Efforts to commercialize the CD38 Product if the JSC selects Everest as the Commercialization Party under this Agreement. Such material breach does not include mistakes
or errors in clinical trials that do not constitute material breach under the MorphoSys Agreement. 

8.3    Termination for Bankruptcy. Each Party shall have the right to terminate this Agreement in its
entirety immediately upon written notice to the other Party, if the other Party shall file in any court or agency pursuant to any statute or regulation of any state or country, a petition in bankruptcy or insolvency or for reorganization or for an

other Party shall be served with an involuntary petition against it, filed in any insolvency proceeding, and such petition shall not be dismissed within ninety (90) calendar days after the filing thereof, or if such other Party shall propose or
be a party to any dissolution or liquidation, or if such other Party shall make an assignment of substantially all of its assets for the benefit of creditors. 

8.4    Termination for Suspension of Development or Commercialization. The Party acknowledge that under the
MorphoSys Agreement, I-Mab shall be deemed to not be using Commercially Reasonable Efforts to develop the CD38 Product if I-Mab fails to initiate or conduct any material
development activities in relation to any therapeutic, prophylactic or palliative CD38 Product for a period of six (6) months. Therefore, the Parties agree that if I-Mab fails to initiate or conduct any
material development activities in relation to any therapeutic, prophylactic or palliative CD38 Product for a period of three (3) months not as a result of any order or requirement of Regulatory Authority, Everest shall have the right to
terminate this Agreement upon written notice to I-Mab. The Parties further agree that if the Commercialization Party fails to initiate or conduct any material commercialization activities after twenty-four
(24) months prior to the anticipated date of first Regulatory Approval of the CD38 Product in relation to the CD38 Product for a period of three (3) months not as a result of any order or requirement of Regulatory Authority, the other
party shall have the right to terminate this Agreement upon written notice to the Commercialization Party. 

8.5    [Intentionally left blank] 

8.6    Effect of Termination. 

(a)    Continuation by I-Mab. If this Agreement is terminated by I-Mab pursuant to Sections 8.2, 8.3, or 8.4, then I-Mab shall have the right to continue the Development and Commercialization of the CD38 Product in the Field in the

 (iv)    transfer and assign to Everest
all inventory of the CD38 Product in I-Mab’s and its Affiliates’ possession; and

the Parties under this Agreement that have accrued prior to the date of expiration or termination. Without limiting the foregoing, the following provisions shall survive any expiration or termination of this Agreement: Sections 5.4, 6.1 - 6.4
