	3.	 PAYMENTS. 



3.1 BioAtla Payment. In exchange for the licenses and other amendments granted to BioAtla pursuant to this Exclusive Agreement, BioAtla
shall pay Company, on the Restatement Date, a one-time, non-refundable, non-creditable license fee by wire transfer of
immediately available funds into an account designated by Company of ten thousand U.S. dollars ($10,000). 
 3.2 Royalties. Subject to
Sections 3.3 and 3.4, Company shall pay to BioAtla: 
 (a) royalties on aggregate annual Net Sales by the Company and its
Affiliates and Licensees of each Product in [***] in each calendar year at the rate of [***] and

[***] 
 3.3 Royalty Term.

 14. 













 3.4 Third Party Licenses. In the event that the Company (or its Affiliate or
Licensee, as applicable) is required to obtain, and obtains, one or more licenses under Patent Rights of Third Parties that are necessary for the manufacture, use or sale solely of the CAB component of a Product in a country (hereinafter
“Third Party Licenses”), the Company may deduct [***] of the royalties actually paid to such Third Party under such Third Party License with respect to sales of such Product in such country from the royalties otherwise
payable to BioAtla under this Agreement with respect to Net Sales of such Product in such country; provided, however, that the royalties payable to BioAtla with respect to Net Sales of such Product in such country may not be reduced by more
than [***] in any calendar quarter as a result of any and all such offsets in the aggregate. Any portion of the royalties paid to such Third Party under such Third Party License with respect to such Product in such country that the Company would,
but for the foregoing limitation on royalty reductions, be entitled to deduct under this Section 3.4 shall be carried over and applied against royalties payable to BioAtla in respect of such Product in such country in subsequent calendar
quarters until the full deduction is taken. 
 3.5 Payment; Reports. Royalties under Section 3.2 shall be calculated and reported
for each calendar quarter and shall be paid within 60 days after the end of each calendar quarter. Each payment shall be accompanied by a report of Net Sales of Products by the Company, its Affiliates and Licensees, which report shall include the
gross sales and Net Sales of each Product (including a statement of deductions taken to calculate Net Sales), the royalties payable, a description of the method used to calculate the royalties payable, and the exchange rates used, in each case
presented on an Product-by-Product and country-by-country basis. 

3.6 Exchange Rate; Manner and Place of Payment. All payments under this Article 3 shall be payable in U.S. dollars by wire transfer
in immediately available funds to a bank and account designated in writing by BioAtla. For the purpose of calculation of Net Sales expressed in currencies other than U.S. Dollars, Company shall convert any amount expressed in a foreign currency into
U.S. Dollar equivalents using a rate of exchange as published in The Wall Street Journal (U.S. Eastern Edition) on last day of the Calendar Quarter in which such Net Sales were made. 

3.7 Audits. The Company shall keep (and shall cause its Affiliates and Licensees to keep) complete and accurate records pertaining to
the sale or other disposition of Products in sufficient detail to permit BioAtla to confirm the accuracy of all royalty payments due hereunder for a period of three years from the end of the calendar year to which such records relate. BioAtla shall
have the right, once annually, to cause an independent, certified public accountant reasonably acceptable to the Company (the “Auditor”) to audit such records solely to confirm Net Sales and
royalties for a period covering not more than the preceding three years. Such audits may be exercised during normal business hours upon reasonable prior written notice to the Company. No calendar year shall be subject to audit under this section
more than once. The Auditor will execute a reasonable written confidentiality agreement with the Company and will disclose to BioAtla only 
  

 
 [***] Certain information in this
document has been omitted from this exhibit because it is both (i) not material and (ii) would be competitively harmful if publicly disclosed. 

  
 15. 













 
such information as is reasonably necessary to provide BioAtla with information regarding any actual or potential discrepancies between amounts reported and actually paid and amounts payable
under this Agreement. The Auditor will send a copy of the report to the Company at the same time it is sent to BioAtla. The report sent to both parties will include the methodology and calculations used to determine the results. Prompt adjustments
shall be made by the parties to reflect the results of such audit. BioAtla shall bear the full cost of such audit unless such audit discloses an underpayment by the Company of more than [***] of the amount due for any calendar year under this
Agreement, in which case, the Company shall bear the full cost of such audit and shall promptly remit to BioAtla the amount of any underpayment. If such audit discloses an overpayment by the Company, then the Company will deduct the amount of such
overpayment from amounts otherwise owed to BioAtla under this Agreement. If such audit discloses an underpayment by the Company, then the Company will pay the amount of such underpayment owed to BioAtla within 30 days. 

3.8 Withholding. BioAtla will pay any and all taxes levied on account of any payments made to it under this Agreement. If any taxes are
paid or required to be withheld by the Company for the benefit of BioAtla on account of any amounts payments payable to BioAtla hereunder, the Company will deduct such taxes from the amount of payments otherwise due to BioAtla, timely pay the taxes
to the proper taxing authority, and send proof of payment to BioAtla within 30 days following such payment. 
 3.9 Late Payments.
In the event that any payment due under Section 3.2 (other than any amount or portion thereof that is subject to good faith dispute between the parties) is not made when due, the payment shall accrue interest from the date due at the rate of
[***] per month; provided, however, that in no event shall such rate exceed the maximum legal annual interest rate. The payment of such interest shall not limit BioAtla from exercising any other rights it may have as a consequence of the
lateness of any payment. 
  

	4.	 CONFIDENTIALITY. 



4.1 Confidential Information. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing by the parties,
each party agrees that, during the Term, and for five years thereafter, such party (the “Receiving Party”) shall keep confidential and shall not publish or otherwise disclose and shall not use for
any purpose other than as expressly provided for in this Agreement any Information furnished to it by the other party (the “Disclosing Party”) pursuant to this Agreement, the Confidentiality
Agreement or the MTA (collectively, “Confidential Information”). Notwithstanding the foregoing, the parties hereby agree that: (a) the Results shall be considered the Confidential Information
of the Company, and the Company shall be deemed the Disclosing Party and BioAtla the Receiving Party with respect thereto; (b) the terms of this Article 4 shall supersede the Confidentiality Agreement and the MTA; and (c) except as
expressly set forth above in the case of Results, any Information disclosed by a party pursuant to the Confidentiality Agreement or the MTA shall be deemed Confidential Information of such party for purposes of this Agreement. The Receiving Party
may use Confidential Information only to the extent required to accomplish the purposes of this Agreement. The Receiving Party will use 
  

 
 [***] Certain information in this
document has been omitted from this exhibit because it is both (i) not material and (ii) would be competitively harmful if publicly disclosed. 

  
 16. 













 
at least the same standard of care as it uses to protect proprietary or confidential information of its own, but no less than reasonable care, to ensure that its employees, agents, consultants
and other representatives do not disclose or make any unauthorized use of the Confidential Information. The Receiving Party will promptly notify the Disclosing Party upon discovery of any unauthorized use or disclosure of the Confidential
Information. 
 4.2 Exceptions. Confidential Information shall not include any information which the Receiving Party can prove by
competent evidence: (a) is now, or hereafter becomes, through no act or failure to act on the part of the Receiving Party in breach of this Agreement, publicly known or available; (b) is known by the Receiving Party at the time of
receiving such information (other than as a result of disclosure by or on behalf of the Disclosing Party), as evidenced by its records; provided, however, that the exception set forth in this clause (b) shall not apply to Results (in the
case of BioAtla as the Receiving Party); (c) is hereafter furnished to the Receiving Party by a Third Party, as a matter of right and without restriction on disclosure; or (d) is independently discovered or developed by the Receiving Party
outside of the R&D Program and without the use of Confidential Information of the Disclosing Party. For purposes of clause (a) of this Section 4.2, no combination of elements within the Confidential Information shall be deemed to be
part of the public domain merely because the individual elements of such combination are part of the public domain, unless the entire combination itself, or the entire principle of use or operation of such combination (if any), is part of the public
domain. In addition, no element within the Confidential Information shall be deemed to be a part of the public domain merely because it is embraced by more general information or data that is part of the public domain. 

4.3 Authorized Disclosure. A Receiving Party may disclose Confidential Information of the Disclosing Party as expressly permitted by
this Agreement (including as reasonably necessary for the Receiving Party’s performance of its obligations under this Agreement), or if and to the extent such disclosure is reasonably necessary in the following instances:

(b) complying with applicable court orders, applicable laws, rules or regulations, or the listing rules of any exchange on which the
Receiving Party’s or its Affiliate’s securities are traded; 
 (c) enforcing the Receiving Party’s rights under this
Agreement; 
 (d) filing or prosecuting Patent Rights as permitted by this Agreement; 

(e) in the case of the Company, disclosure in regulatory submissions with respect to F1 Products within the scope of the Exclusive
ACT License; 
 (f) in the case of BioAtla, disclosure in regulatory submissions with respect to BioAtla CAB Non-ACT Products within the scope of the Exclusive Non-ACT License; 

(g) disclosure to the Receiving Party’s Affiliates, to the Company’s actual or potential licensees or sublicensees of rights
with respect to F1 Products, to BioAtla’s actual or potential licensees or sublicensees of rights with respect to BioAtla CAB Non-ACT Products, and to the Receiving Party’s and its
Affiliates’ Representatives who, in each case, have a need to know such information in order for the Receiving Party to exercise its rights or fulfill its obligations under this Agreement, provided, in each case, that any such Affiliate, actual
or potential licensee or sublicensee, or Representative agrees to be bound by terms of confidentiality and non-use at least as restrictive as those set forth in this Article 4; and 

  
 17. 













 (h) disclosure to Third Parties in connection with due diligence or similar
investigations by such Third Parties, and disclosure to potential Third Party investors in confidential financing documents, provided, in each case, that any such Third Party agrees to be bound by reasonable obligations of confidentiality and non-use. 
 Notwithstanding the foregoing, in the event the Receiving Party is required to make a
disclosure of the Disclosing Party’s Confidential Information pursuant to Section 4.3(a) or 4.3(b), it will, except where impracticable, (i) give reasonable advance notice to the Disclosing Party of such disclosure, (ii) use
efforts to secure confidential treatment of such information at least as diligent as the Receiving Party would use to protect its own confidential information, but in no event less than reasonable efforts, and (iii) cooperate with any efforts
by the Disclosing Party, at the Disclosing Party’s request and expense, to secure confidential treatment of such Confidential Information.

and their respective officers, directors, agents, employees, successors and assigns (the “BioAtla Indemnitees”), from and against any and all losses, damages, liabilities, expenses and costs,
including reasonable legal expense and attorneys’ fees (“Losses”), to which any BioAtla Indemnitee may become subject as a result of any claim, demand, action or other proceeding by any Third
Party (each, a “Claim”) to the extent such Losses arise out of or relate to: (a) the development, manufacture, use, handling, storage, sale, offer for sale, import or other disposition by or
on behalf of the Company, its Affiliates, licensees or sublicensees of F1 Products, or any other exercise of the Exclusive ACT License by or on behalf of the Company, its Affiliates or sublicensees; (b) the gross negligence or willful
misconduct of any Company Indemnitee (defined below); or (c) the breach by the Company of any warranty, representation, covenant or agreement made by the Company in this Agreement; except, in each case, to the extent such Losses result from the
gross negligence or willful misconduct of any BioAtla Indemnitee or the breach by BioAtla of any warranty, representation, covenant or agreement made by BioAtla in this Agreement. 

8.2 Indemnification by BioAtla. BioAtla hereby agrees to save, defend, indemnify and hold harmless the Company, its Affiliates and their
respective officers, directors, employees, consultants and agents (the “Company Indemnitees”) from and against any and all Losses to which any Company Indemnitee may become subject as a result of
any claim, demand, action or other proceeding by any Third Party to the extent such Losses arise out of or relate to: (a) the development, manufacture, use, handling, storage, sale, offer for sale, import or other disposition by or on behalf of
BioAtla, its Affiliates, licensees or sublicensees of BioAtla CAB Non-ACT Products, or any other exercise of the Exclusive Non-ACT License by or on behalf of BioAtla,
its Affiliates, licensees or sublicensees; (b) the gross negligence or willful misconduct of any BioAtla Indemnitee; or (c) the breach by BioAtla of any warranty, representation, covenant or agreement made by BioAtla in this Agreement; in

 8.3 Control of Defense. In the event a party (the “Indemnified Party”) seeks
indemnification under Section 8.1 or 8.2, it shall inform the other party (the “Indemnifying Party”) of a claim as soon as reasonably practicable after it receives notice of the claim (it
being understood and agreed, however, that the failure by an Indemnified Party to give notice of a claim as provided in this Section 8.3 shall not relieve the Indemnifying Party of its indemnification


  
 27. 













 
obligation under this Agreement except and only to the extent that such Indemnifying Party is actually damaged as a result of such failure to give notice), shall permit the Indemnifying Party to
assume direction and control of the defense of the claim (including the right to settle the claim solely for monetary consideration) using counsel reasonably satisfactory to the Indemnified Party, and shall cooperate as requested (at the expense of
the Indemnifying Party) in the defense of the claim. If the Indemnifying Party does not assume control of such defense within 15 days after receiving notice of the claim from the Indemnified Party, the Indemnified Party shall control such
defense and, without limiting the Indemnifying Party’s indemnification obligations, the Indemnifying Party shall reimburse the Indemnified Party for all costs, including reasonable attorney fees, incurred by the Indemnified Party in defending
itself within 30 days after receipt of any invoice therefor from the Indemnified Party. The party not controlling such defense may participate therein at its own expense. The party controlling such defense shall keep the other party advised of
the status of such action, suit, proceeding or claim and the defense thereof and shall consider recommendations made by the other party with respect thereto. The Indemnified Party shall not agree to any settlement of such action, suit, proceeding or
claim without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld, delayed or conditioned. The Indemnifying Party shall not agree to any settlement of such action, suit, proceeding or claim or consent to any
judgment in respect thereof that does not include a complete and unconditional release of the Indemnified Party from all liability with respect thereto, that imposes any liability or obligation on the Indemnified Party or that acknowledges fault by
the Indemnified Party without the prior written consent of the Indemnified Party. If the parties cannot agree as to the application of Section 8.1 or 8.2 to any claim, pending resolution of the dispute pursuant to Article 9, the parties
may conduct separate defenses of such claims, with each party retaining the right to claim indemnification from the other party in accordance with Section 8.1 or 8.2, as applicable, upon resolution of the underlying claim. 

8.4 Insurance. Each party shall procure and maintain insurance, including comprehensive or commercial general liability insurance
(including contractual liability and product liability), adequate to cover its obligations hereunder and which is consistent with normal business practices of prudent companies similarly situated. It is understood that such insurance shall not be
construed to create a limit of either party’s liability with respect to its indemnification obligations under this Article 8 or otherwise. Each party shall provide the other party with written evidence of such insurance upon request. 

 

	9.	 DISPUTE RESOLUTION. 



9.1 Disputes. Subject to Section 9.3, any claim, dispute, or controversy as to the breach, enforcement, interpretation or validity
of this Agreement (each, a “Dispute”) will be referred to the Chief Executive Officer of the Company and the Chief Executive Officer of BioAtla (the
“Executives”) for attempted resolution. In the event such Executives are unable to resolve such Dispute within 30 days of such Dispute being referred to them, then, upon the written request of
either party to the other party, the Dispute shall be subject to arbitration in accordance with Section 9.2, except as expressly set forth in Section 9.3. 

  
 28. 














	9.2	 Arbitration. 



(a) Claims. Subject to Section 9.3 below, any Dispute that is not resolved under Section 9.1 within the applicable 30-day period shall be resolved by final and binding arbitration administered by JAMS (the “Administrator”) in accordance with its then-effective Comprehensive Arbitration Rules and
Procedures (the “Rules”), except to the extent any such Rule conflicts with the express provisions of this Section 9.2. (Capitalized terms used but not otherwise defined in this Agreement shall have the meanings provided
in the Rules.) The Arbitration shall be conducted by three neutral arbitrators, each of whom shall be a lawyer with at least 15 years of experience with a law firm or corporate law department of over 25 lawyers and at least 10 years
representing (either as outside counsel or in-house counsel) companies in the pharmaceutical or biotechnology industry in connection with licensing transactions, provided that no such individual shall be a
current or former employee or director, or a current stockholder, of either party or any of their respective Affiliates. Each party shall appoint one arbitrator, and the two so-appointed arbitrators shall
jointly nominate the third arbitrator who shall become the chairman. If such nomination of the chairman does not take place within 30 days from the nomination of the last co-arbitrator, the chairman shall
be selected in accordance with the Rules. The arbitration and all associated discovery proceedings and communications shall be conducted in English, and the arbitration shall be held in New York, New York, USA. 

(b) Discovery. Within 30 days after selection of the third arbitrator, the arbitrators shall conduct the Preliminary Conference. In
addressing any of the subjects within the scope of the Preliminary Conference, the arbitrators shall take into account both the desirability of making discovery efficient and cost-effective and the needs of the parties for an understanding of any
legitimate issue raised in the Arbitration. In that regard, the parties agree to the application of the E-Discovery procedures set forth in Rule 16.2(c) of the JAMS Expedited Procedures. In addition, each
party shall have the right to take up to 40 hours of deposition testimony, including expert deposition testimony. 
 (c) Hearing;
Decision. The Hearing shall commence within 60 days after the discovery cutoff. The arbitrators shall require that each party submit concise written statements of position and shall permit the submission of rebuttal statements, subject to
reasonable limitations on the length of such statements to be established by the arbitrators. The Hearing shall be no longer than 5 Business Days in duration. The arbitrators shall also permit the submission of expert reports. The arbitrators
shall render the Award within 30 days after the arbitrators declares the Hearing closed, and the Award shall include a written statement describing the essential findings and conclusions on which the Award is based, including the calculation of
any damages awarded. The arbitrators will, in rendering their decision, apply the substantive law of the State of California, USA, without giving effect to its principles of conflicts of law. The arbitrators’ authority to award special,
incidental, consequential or punitive damages shall be subject to the limitation set forth in Section 6.7. The Award rendered by the arbitrators shall be final, binding and non-appealable, and judgment
may be entered upon it in any court of competent jurisdiction. 
 (d) Costs. Each party shall bear its own attorney’s fees,
costs, and disbursements arising out of the arbitration, and shall pay an equal share of the fees and costs of the arbitrator. 

  
 29. 













 9.3 Court Actions. Nothing contained in this Agreement shall deny either party the
right to seek injunctive or other equitable relief from a court of competent jurisdiction in the context of a bona fide emergency or prospective irreparable harm, and such an action may be filed and maintained notwithstanding any ongoing
discussions between the parties or any ongoing arbitration proceeding. In addition, either party may bring an action in any court of competent jurisdiction to resolve disputes pertaining to the validity, construction, scope, enforceability,
infringement or other violations of Patent Rights or other intellectual property rights, and no such claim shall be subject to arbitration pursuant to Section 9.2. 
  

	10.	 NATURE AND EFFECTIVENESS OF
AGREEMENT. 


 This Agreement is binding upon BioAtla and Company as of the 2019 Execution Date, and this Article 10 and
11 are effective as of the 2019 Execution Date, but the remainder of this Agreement shall become effective only when Company has entered into agreements with the holder of each note listed on Exhibit C to modify or convert each of said notes.
Company shall provide to BioAtla written notice not later than 2 business days after execution of the final noteholder agreement and the Restatement Date shall be the date such notice is delivered (the “Restatement
Date”). If Company has not provided such written notice on or before January 5th, 2020, or such later date as the parties mutually agree (the “End
Date”), either party shall have the right to withdraw from and terminate this Agreement within 5 days after the End Date upon written notice to the other party and, effective upon such withdrawal, the Original Agreement shall remain in
full force and effect on the same terms and conditions as it existed before execution of this Agreement and this Agreement shall automatically become null and void ab initio. Notwithstanding anything to the contrary, the parties understand
and agree that, if the Company is unable to achieve the Restatement Date by the End Date, then BioAtla shall have the right to withdraw from and terminate this Agreement within 5 days after the End Date upon written notice to Company and, if such
withdrawal and termination occurs, the Parties hereby covenant and agree that effective as of such withdrawal and termination the Original Agreement shall be terminated with immediate effect, in accordance with Section 9.2 thereof, and the
parties further agree that such termination of the Original Agreement shall not relieve either party of any obligation or liability accruing thereunder prior to such termination, nor shall such termination preclude either party from pursuing all
rights and remedies it may have under the Original Agreement, at law or in equity, with respect to breach of the Original Agreement, and the parties’ rights and obligations under Sections 6.1, 6.2, and 6.3 and Articles 6 (Confidentiality),
10 (Indemnification), 11 (Dispute Resolution), and 12 (Miscellaneous) of the Original Agreement shall survive such termination of the Original Agreement. 
  

	11.	 MISCELLANEOUS. 



11.1 Rights Upon Bankruptcy. All rights and licenses granted under or pursuant to this Agreement are, and shall otherwise be deemed to
be, for purposes of Section 365(n) of Title 11 of the United States Code and other similar laws in any jurisdiction outside the US (collectively, the “Bankruptcy Laws”), licenses of rights to be “intellectual

performed by such

and its successors and assigns (including a Title 11 trustee), shall provide to the other party copies of all Information necessary for such other party to prosecute, maintain and enjoy its rights under the terms of this Agreement promptly upon
such other party’s written request therefor. All rights, powers and remedies of the non-bankrupt party as provided herein are in addition to and not in substitution for any and all other rights, powers

 11.4 Non-Waiver. The failure of a party to insist upon strict performance of any provision of this Agreement or to exercise any right arising out of this Agreement shall neither impair that provision or right nor
constitute a waiver of that provision or right, in whole or in part, in that instance or in any other instance. Any waiver by a party of a particular provision or right shall be in writing, shall be as to a particular matter and, if applicable, for
a particular period of time and shall be signed by such party.

this Agreement nor any rights or obligations hereunder may be assigned or otherwise transferred by either party without the prior written consent of the other party (which consent shall not be unreasonably withheld); provided, however, that,
(i) the Company may assign this Agreement and its rights and obligations hereunder without BioAtla’s consent, and (ii) BioAtla may assign this Agreement and its rights and obligations hereunder without the Company’s consent: 

(a) in connection with the transfer or sale of all or substantially all of the business of such party to which this Agreement relates to
a Third Party (“Third Party Acquirer”), whether by merger, sale of stock, sale of assets or otherwise (each, a “Sale Transaction”), provided that
in the event of a Sale Transaction (whether this Agreement is actually assigned or is assumed by the Third Party Acquirer or the surviving corporation resulting from such Sale Transaction by operation of law (e.g., in the context of a reverse

The rights and obligations of the parties under this Agreement shall be binding upon and inure to the benefit of the successors and permitted
assigns of the parties, and the name of a party appearing herein will be deemed to include the name of such party’s successors and permitted assigns to the extent necessary to carry out the intent of this section. Any assignment not in
accordance with this Agreement shall be void. 
 11.6 Force Majeure. Each party shall be excused from liability for the failure or
delay in performance of any obligation under this Agreement by reason of any event beyond such party’s reasonable control, including but not limited to Acts of God, fire, flood, explosion, earthquake, or other natural forces, war, civil unrest,
acts of terrorism, accident, destruction or other casualty, any lack or failure of transportation facilities, any lack or failure of supply of raw materials, any strike or labor disturbance, or any other event similar to those enumerated above. Such
excuse from liability shall be effective only to the extent and duration of the event(s) causing the failure or delay in performance and provided that the party has not caused such event(s) to occur. The affected party shall notify the other party
of such force majeure circumstances as soon as reasonably practical, and shall promptly undertake all reasonable efforts necessary to cure such force majeure circumstances. 

11.7 Severability. If any one or more of the provisions contained in this Agreement is held invalid, illegal or unenforceable in any
respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby, unless the absence of the invalidated provision(s) adversely affects the substantive rights of the
parties. The parties shall in such an instance use their best efforts to replace the invalid, illegal or unenforceable provision(s) with valid, legal and enforceable provision(s) which, insofar as practical, implement the purposes of this Agreement.

 11.8 Notices. Any notice to be given under this Agreement must be in writing and delivered either in person, by any method of mail
