limited to, any Bispecific Product conjugated, fused, or operatively linked directly or indirectly with a cytotoxic or cytostatic compound or radionuclide (or any other method of delivering a toxic moiety to a cell using an Antibody), but excludes a
Genetically Engineered Cellular Therapy or CAR-T Licensed Product (defined below). 


  

	1.2	 “Affiliate” means any corporation or other business entity which is bound in writing by LICENSEE to
the terms set forth in this Agreement and in which LICENSEE owns or controls, directly or indirectly, at least fifty percent (50%) of the outstanding stock or other voting rights entitled to elect directors, or in which LICENSEE is owned or
controlled directly or indirectly by at least fifty percent (50%) of the outstanding stock or other voting rights entitled to elect directors; but in any country where the local law does not permit foreign equity participation of at least fifty
percent (50%), then an “Affiliate” includes any company in which LICENSEE owns or controls or is owned or controlled by, directly or indirectly, the maximum percentage of outstanding stock or voting rights permitted by local law.



  

	1.3	 “Antibody” means all forms of antibodies, including, but not limited to: murine, chimeric,
primatized, humanized, de-immunized and human; as well as all intact antibodies and fragment.

Costs”), UNIVERSITY will inform LICENSEE no less than sixty (60) days prior to the date when Anticipated Costs are incurred. UNIVERSITY may, at its discretion and in accordance with Paragraph 5.l(c), require full advance payment of
Anticipated Costs at least fifteen (15) business days before required filing dates (“Advance Payment Deadline”). In the event UNIVERSITY has provided LICENSEE with a sixty (60) days’ notice of Anticipated Costs, and LICENSEE
does not pay the Anticipated Costs on or 



  
 10 

			
	Eff. 4/18/12	  	OAL FINAL















	 	 
before the Advance Payment Deadline, UNIVERSITY will act at its sole discretion with regard to filing, prosecution and maintenance of those Patent Rights associated with the sixty
(60) days’ notice. In the event that the Anticipated Costs paid by LICENSEE is greater than the actual cost, the excess amount is creditable against future Patent Costs. In the event that the actual costs exceed the Anticipated Costs paid
in advance by LICENSEE, LICENSEE shall pay such excess costs within thirty (30) days following the date an itemized invoice is sent as set forth in Paragraph 4.3. 



 

	    	 In the event that UNIVERSITY licenses Patent Rights to a third party (“Additional Licensee”),
UNIVERSITY shall cause any Additional Licensee to pay a pro-rata share of future Patent Costs after the execution date of the Additional Licensee’s license. For purposes if this Paragraph 3.2, “pro-rata” shall mean a fractional share of the total Patent Costs multiplied by a fraction, the numerator of which is one and the denominator of which is the Additional Licensee plus one.



  

	3.3	 Due Diligence. 



 

	 	(a)        LICENSEE	 shall, either directly or through its Affiliate(s) or Sublicensee(s): 



(i)        diligently proceed with the development, manufacture and sale of Licensed Products; 

(ii)        annually spend not less than [***] for the development of Licensed Products during the
first five (5) years of this Agreement. LICENSEE recognizes the expertise of the Inventors in Inventions and, pursuant to Paragraph 3.4 below, is committed to contract the Inventors to further develop Inventions at UCSD of at least [***]
per year for a total of five years. LICENSEE may credit the amount actually paid to UCSD under such contract against its obligation under this paragraph; 

(iii)        market Licensed Products in the United States within nine (9) months of receiving
regulatory approval to market such Licensed Products; 
 (iv)        fill the market demand for
Licensed Products following commencement of marketing at any time during the term of this Agreement; and

 (b) If LICENSEE fails to perform any of its obligations specified in Paragraph 3.3(a)
in any Licensed Product category (e.g. Antibody Licensed Product or Genetically Engineered Cellular Therapy or CAR-T Licensed Product), then UNIVERSITY shall have the right and option, if LICENSEE fails to
cure such breach or provide an acceptable plan of action to cure such breach, to either terminate this Agreement or change LICENSEE’s exclusive license to a nonexclusive license with respect to such Licensed Product category. This right, if
exercised by UNIVERSITY, supersedes the rights granted in Article 2. 
 The deadlines for the diligence milestones set forth in
Paragraph 3.3(a) above shall be extended by the length of any delay caused by a regulatory authority where such delay by the regulatory authority was not the result of the LICENSEE’s actions or inactions and was not the result of the
LICENSEE’s failure to abide by the regulatory authority’s instructions or LICENSEE’s failure to provide data to the regulatory authority in the form and manner required by such regulatory authority. 

In the event of delays due to efficacy and/or safety of Licensed Products and beyond the control of LICENSEE, LICENSEE and UNIVERSITY shall
discuss in good faith extensions of the time-lines presented in Paragraph 3.3(a) above. 
  

	3.4	 Research Support. LICENSEE agrees to provide research support to Inventors to further develop the
Inventions at UCSD in the amount of not less than five hundred thousand dollars (US$500,000) in the aggregate per year for five (5) years under sponsored research agreements (“Sponsored Research Agreements”) to be negotiated by
LICENSEE with the UCSD Office of Contract and Grant Administration. In consideration of the foregoing, LICENSEE shall enter into a Sponsored Research Agreement conducted under the direction of Dr. Thomas Kipps, MD within thirty (30) days
of the Effective Date. All amounts paid by LICENSEE to UNIVERSITY under the Sponsored Research Agreement shall cumulatively count towards LICENSEE’s annual spend obligation under Article 3.3(a)(ii). 



In addition, and to the extent such financial support is required by CIRM, LICENSEE agrees to provide support for up to [***] of the costs of
the CIRM-funded clinical trial of UC-961 up to [***] year (prorated for any partial year that the clinical trial grant is in effect), under a Clinical Trials Agreement which will be executed within forty-five
(45) days from the Effective Date. 
 ARTICLE 4. REPORTS, RECORDS AND PAYMENTS

 13 

			
	Eff. 4/18/12	  	OAL FINAL














 
approvals necessary for marketing the same. Such semiannual reports shall be due within sixty (60) days of the reporting period and include a summary of work completed, summary of work in
progress, current schedule of anticipated events or milestones, market plans for introduction of Licensed Products, and summary of resources (dollar value) spent in the reporting period. The reports referred to in this Paragraph 4.1(a) should
be marked with the following title and case number: “License Agreement between UCSD and Oncternal Therapeutics, Inc. for case SD2012-143.” Reports shall be submitted as attachment to UCSD’s
email address: oic-reports@ucsd.edu. 

(b)        Royalty Reports. 

After the first commercial sale of a Licensed Product anywhere in the world, LICENSEE shall submit to UNIVERSITY quarterly royalty reports on
or before each February 28, May 31, August 31 and November 30 of each year. Each royalty report shall cover LICENSEE’s (and each Affiliate’s and Sublicensee’s) most recently completed calendar quarter and shall
show: 
 (i)        the date of first commercial sale of a Licensed Product in each country; 

(ii)        the gross sales, deductions as provided in Paragraph 1.12 (Net Sales), and Net Sales
during the most recently completed calendar quarter and the royalties, in US dollars, payable with respect thereto;

If no sales of Licensed Products have been made and no Sublicense revenue has been received by LICENSEE during any reporting period, LICENSEE
shall so report. The reports referred to in this Paragraph 4.1(b) should be marked with the following title and case number: “License Agreement between UCSD and Oncternal Therapeutics, Inc. for case
SD2015-143.” Reports shall be submitted as attachment to UCSD’s email address: oic-reports@ucsd.edu. 

(c)        Timely Reports. 

LICENSEE acknowledges the important value that timely reporting provides in the UNIVERSITY’s effective management of its rights under
this Agreement. LICENSEE further acknowledges that failure to render the reports required under this Paragraph 4.1 may harm UNIVERSITY’s ability to manage its rights under this Agreement. As such, reports not submitted by the required due
date under this Paragraph 4.1 will cause to be due by LICENSEE to UNIVERSITY a late reporting fee of five hundred dollars (US$500.00) per month until such report, compliant with the requirements of this


  
 14 

			
	Eff. 4/18/12	  	OAL FINAL














 
Paragraph 4.1, is received by UNIVERSITY. Payment of this fee is subject to Paragraph 4.3 and Paragraph 10.1 herein. 

 

	4.2	 Records & Audits. 



(a)        LICENSEE shall keep, and shall require its Affiliates and Sublicensees to keep, accurate
and correct records of all Licensed Products manufactured, used, and sold, and Sublicense fees received under this Agreement. Such records shall be retained by LICENSEE for at least five (5) years following a given reporting period. 

(b)         All records shall be available during normal business hours for inspection at the expense
of UNIVERSITY by UNIVERSITY’s Internal Audit Department or by a Certified Public Accountant selected by UNIVERSITY and reasonably acceptable to LICENSEE and in compliance with the other terms of this Agreement for the sole purpose of verifying
reports and payments or other compliance issues no more than one time for each annual period. If LICENSEE rejects three choices of CPAs suggested by UNIVERSITY, then UNIVERSITY may choose a CPA without concurrence by LICENSEE. Such inspector shall
not disclose to UNIVERSITY any information other than information relating to the accuracy of reports and payments made under this Agreement or other compliance issues. In the event that any such inspection shows an under reporting and underpayment
in excess of [***] for any twelve-month (12-month) period, then LICENSEE shall pay the cost of the audit as well as any additional sum that would have been payable to UNIVERSITY had the LICENSEE reported
correctly, plus an interest charge at a rate of [***] per year. Such interest shall be calculated from the date the correct payment was due to UNIVERSITY up to the date when such payment is actually made by LICENSEE. For underpayment not in excess
of [***] for any twelve-month (12-month) period, LICENSEE shall pay the difference within thirty (30) days without interest charge or inspection cost. 

 

	4.3	 Payments. 



(a)        All fees, reimbursements and royalties due UNIVERSITY shall be paid in United States
dollars and all checks (should payment by wire not be possible) shall be made payable to “The Regents of the University of California”, referencing UNIVERSITY’s taxpayer identification number,
95-6006144, and sent to UNIVERSITY according to Paragraph 10.l (Correspondence). When Licensed Products are sold in currencies other than United States dollars, LICENSEE shall first determine the earned
royalty in the currency of the country in which Licensed Products were sold and then convert the amount into equivalent United States funds, using the average of the exchange rate quoted in the Wall Street Journal for the thirty (30) days prior
to the end of the applicable reporting period. 
 (b)        Royalty Payments. 

(i)        Royalties shall accrue when Licensed Products are invoiced, or if not invoiced, when
delivered to a third party or Affiliate. 

  
 15 

			
	Eff. 4/18/12	  	OAL FINAL














 (ii)         LICENSEE shall pay earned royalties
quarterly on or before February 28, May 31, August 31 and November 30 of each calendar year. Each such payment shall be for earned royalties accrued within LICENSEE’s most recently completed calendar quarter. 

(iii)         Royalties earned on sales occurring or under Sublicense granted pursuant to this
Agreement in any country outside the United States shall not be reduced by LICENSEE for any taxes, fees, or other charges imposed by the government of such country on the payment of royalty income, except that all payments made by LICENSEE in
fulfillment of University’s tax liability in any particular country may be credited against earned royalties or fees due UNIVERSITY for that country. LICENSEE shall pay all bank charges resulting from the transfer of such royalty payments. 

(iv)        If at any time legal restrictions prevent the prompt remittance of part or all royalties
by LICENSEE with respect to any country where a Licensed Product is sold or a Sublicense is granted pursuant to this Agreement, LICENSEE shall convert the amount owed to UNIVERSITY into US currency and shall pay UNIVERSITY directly from its US
sources of funds for as long as the legal restrictions apply. 
 (v)        LICENSEE shall not
collect royalties from, or cause to be paid on Licensed Products sold to the account of the US Government or any agency thereof as provided for in the license to the US Government. 

(vi)        In the event that any patent or patent claim within Patent Rights is held invalid in a
final decision by a patent office from which no appeal or additional patent prosecution has been or can be taken, or by a court of competent jurisdiction and last resort and from which no appeal has or can be taken, all obligation to pay royalties
based solely on that patent or claim or any claim patentably indistinct therefrom shall cease as of the date of such final decision. LICENSEE shall not, however, be relieved from paying any royalties that accrued before the date of such final
decision, that are based on another patent or claim not involved in such final decision. 

(vii)        Royalty payments under Article 3, recoveries and settlements under Article 5, and
royalty reports under 4.l(b) shall be rendered for any and all Licensed Products even if due after expiration of the Agreement. If no applicable Patent Rights existed in the Territory at the time of any making, use, sale, offer for sale, or import,
then no royalty payments or royalty reports shall be due. 
 (c)        Late Payments.
In the event royalty, reimbursement and/or fee payments are not received by UNIVERSITY when due, LICENSEE shall pay to UNIVERSITY interest charges at a rate of [***] per year. Such interest shall be calculated from the date payment was due until
actually received by UNIVERSITY.

 ARTICLE 5. PATENT MATTERS 

 

	5.1	 Patent Prosecution and Maintenance. 



(a)         Provided that LICENSEE has reimbursed UNIVERSITY for Patent Costs pursuant to
Paragraph 3.2, UNIVERSITY shall diligently prosecute and maintain the United States and, if available, foreign patents, and applications in Patent Rights using counsel of its choice. UNIVERSITY shall provide LICENSEE with copies of all relevant
documentation relating to such prosecution to allow for review and comment by LICENSEE, including discussion among relevant entities (i.e. entities with interests in the Patent Rights) to the extent appropriate. UNIVERSITY shall reasonably consider
all such comments, provided, however, if the LICENSEE has not commented upon such documentation in a reasonable time for UNIVERSITY to sufficiently consider LICENSEE’s comments prior to a deadline with the relevant government patent office, or
UNIVERSITY must act to preserve the Patent Rights, UNIVERSITY will be free to respond without consideration of LICENSEE’s comments, if any. LICENSEE shall keep this documentation confidential. The counsel shall take instructions only from
UNIVERSITY, and all patents and patent applications in Patent Rights shall be assigned solely to UNIVERSITY. UNIVERSITY shall in any event control all patent filings and all patent prosecution decisions and related filings (e.g. responses to office
actions) shall be at UNIVERSITY’s final discretion (prosecution includes, but is not limited to, interferences, oppositions and any other inter partes matters originating in a patent office). 

(b)        UNIVERSITY shall consider amending any patent application in Patent Rights to include
claims reasonably requested by LICENSEE to protect the products contemplated to be sold by LICENSEE under this Agreement. 

(c)         LICENSEE may elect to terminate its reimbursement obligations with respect to any patent
application or patent in Patent Rights upon three (3) months’ written notice to UNIVERSITY. UNIVERSITY shall use reasonable efforts to curtail further Patent Costs for such application or patent when such notice of termination is received
from LICENSEE. UNIVERSITY, in its sole discretion and at its sole expense, may continue prosecution and maintenance of said application or patent, and LICENSEE shall have no further license with respect thereto.
Non-payment of any portion of Patent Costs or Anticipated Costs with respect to any application or patent may be deemed by UNIVERSITY as an election by LICENSEE to terminate its reimbursement obligations with
respect to such application or patent. UNIVERSITY is not obligated at any time to file, prosecute, or maintain Patent Rights in a country, where, for that country’s patent application LICENSEE is not paying Patent Costs or Anticipated Costs, or
to file, prosecute, or maintain Patent Rights to which LICENSEE has terminated its license hereunder. 

(d)        LICENSEE shall apply for an extension of the term of any patent in Patent Rights if
appropriate under the Drug Price Competition and Patent Term Restoration Act of 1984 and/or European, Japanese and other foreign counterparts of this law. LICENSEE shall prepare all documents for such application, and, if requested by LICENSEE,


  
 17 

			
	Eff. 4/18/12	  	OAL FINAL














 
UNIVERSITY shall execute such documents and take any other additional action as LICENSEE reasonably requests in connection therewith. 

 

	5.2	 Patent Infringement. 



(a)         In the event that UNIVERSITY (to the extent of the actual knowledge of the licensing
professional responsible for the administration of this Invention) or LICENSEE learns of infringement of potential commercial significance of any patent licensed under this Agreement, the knowledgeable party will provide the other (i) with
written notice of such infringement and (ii) with any evidence of such infringement available to it (the “Infringement Notice”). During the period in which, and in the jurisdiction where, LICENSEE has exclusive rights under this
Agreement, neither UNIVERSITY nor LICENSEE will notify a third party (including the infringer) of infringement or put such third party on notice of the existence of any Patent Rights without first obtaining consent of the other. If LICENSEE notifies
a third party of infringement or puts such third party on notice of the existence of any Patent Rights with respect to such infringement without first obtaining the written consent of UNIVERSITY and UNIVERSITY is sued in declaratory judgment,
UNIVERSITY shall have the right to terminate this Agreement immediately without the obligation to provide sixty (60) days’ notice as set forth in Paragraph 7.1. Both UNIVERSITY and LICENSEE will use their diligent efforts to cooperate
with each other to terminate such infringement without litigation. 
 For the avoidance of doubt, this paragraph 5.2(a) does not
prevent LICENSEE or UNIVERSITY from consulting its counsel or insurance providers or prevents LICENSEE from patent marking according to paragraph 5.3. 

(b)         If infringing activity of potential commercial significance with respect to the Field by
the infringer has not been abated within ninety (90) days following the date the Infringement Notice takes effect, LICENSEE may institute suit for patent infringement against the infringer. UNIVERSITY may voluntarily join such suit at its own
expense, but may not thereafter commence suit against the infringer for the acts of infringement that are the subject of LICENSEE’s suit or any judgment rendered in that suit. LICENSEE may not join UNIVERSITY in a suit initiated by LICENSEE
without UNIVERSITY’S prior written consent. If, in a suit initiated by LICENSEE, UNIVERSITY is involuntarily joined other than by LICENSEE, LICENSEE will pay any costs incurred by UNIVERSITY arising out of such suit, including but not limited
to, any legal fees of counsel that UNIVERSITY selects and retains to represent it in the suit. 

(c)         If, within a hundred and twenty (120) days following the date the Infringement Notice
takes effect, infringing activity of potential commercial significance with respect to the Field by the infringer has not been abated and if LICENSEE has not brought suit against the infringer, UNIVERSITY may institute suit for patent infringement
against the infringer. If UNIVERSITY institutes such suit, LICENSEE may not join such suit without UNIVERSITY’S consent and may not thereafter commence suit against the infringer for the acts of infringement that are the subject of
UNIVERSITY’S suit or any judgment rendered in that suit. 

  
 18 

			
	Eff. 4/18/12	  	OAL FINAL














 (d)        Notwithstanding anything to the contrary
in this Agreement, in the event that the infringement or potential infringement pertains to an issued patent included within the Patent Rights and written notice is given under any statute expediting litigation (e.g. the Drug Price Competition and
Patent Term Restoration Act of 1984 and/or foreign counterparts of this Law or the Biologics Price Competition and Innovation Act) (“Act”), then the party in receipt of such notice under the Act (in the case of UNIVERSITY to the extent of
the actual knowledge of the licensing officer responsible for the administration of this Agreement) shall provide the Infringement Notice to the other party promptly. If the time period is such that the LICENSEE will lose the right to pursue legal
remedy for infringement with respect to the Field by not notifying a third party or by not filing suit, the notification period and the time period to file suit will be accelerated to within forty-five (45) days of the date of such notice under
the Act to either party. 
 (e)        Any recovery or settlement received in connection with any
suit will first be shared by UNIVERSITY and LICENSEE equally to cover the litigation costs each incurred, and next shall be paid to UNIVERSITY or LICENSEE to cover any litigation costs it incurred in excess of the litigation costs of the other. In
any suit initiated by LICENSEE, any recovery in excess of litigation costs will be shared between LICENSEE and UNIVERSITY as follows: (i) for any recovery other than amounts paid for willful infringement: (A) UNIVERSITY will receive [***]
of the recovery if UNIVERSITY was not a party in the litigation and did not incur any litigation costs; (B) UNIVERSITY will receive [***] of the recovery if UNIVERSITY was a party in the litigation, but did not incur any litigation costs,
including the provisions of Paragraph 5.2(b) above, or (C) UNIVERSITY will receive [***] of the recovery if UNIVERSITY incurred any unreimbursed litigation costs in connection with the litigation; and (ii) for any recovery for willful
infringement, UNIVERSITY will receive [***] of the recovery. In any suit initiated by UNIVERSITY, any recovery in excess of the litigation costs for UNIVERSITY AND LICENSEE will belong to UNIVERSITY. UNIVERSITY and LICENSEE agree to be bound by all
final and unappealable determinations of patent infringement, validity, and enforceability (but no other issue) resolved by any adjudicated judgment in a suit brought in compliance with this Paragraph 5.2. 

(f)        Any agreement made by LICENSEE for purposes of settling litigation or other dispute shall
comply with the requirements of Paragraph 2.2 (Sublicenses) of this Agreement. 

(g)        Each party will cooperate with the other in litigation proceedings instituted hereunder but
at the expense of the party who initiated the suit (unless such suit is being jointly prosecuted by the parties). 

(h)        Any litigation proceedings will be controlled by the party bringing the suit, except that
UNIVERSITY may be represented by counsel of its choice in any suit brought by LICENSEE. 
  

	5.3	 Patent Marking. LICENSEE shall mark all Licensed Products made, used or sold under the terms of
this Agreement, or their containers, in accordance with the applicable patent marking laws. LICENSEE shall be responsible for all monetary and legal liabilities 



  
 19 

			
	Eff. 4/18/12	  	OAL FINAL














 
arising from or caused by (i) failure to abide by applicable patent marking laws and (ii) any type of incorrect or improper patent marking. 

ARTICLE 6. GOVERNMENTAL MATTERS 
  

	6.1	 Governmental Approval or Registration. If this Agreement or any associated transaction is required by
the law of any nation to be either approved or registered with any governmental agency, LICENSEE shall assume all legal obligations to do so. LICENSEE shall notify UNIVERSITY if it becomes aware that this Agreement is subject to a United States or
foreign government reporting or approval requirement. LICENSEE shall make all necessary filings and pay all costs including fees, penalties, and all other out-of-pocket
costs associated with such reporting or approval process. 


  

	6.2	 Export Control Laws. LICENSEE shall observe all applicable United States and foreign laws with respect
to the transfer of Licensed Products and related technical data to foreign countries, including, without limitation, the International Traffic in Arms Regulations and the Export Administration Regulations. 



 

	6.3	 Preference for United States Industry. If LICENSEE sells a Licensed Product or Combination Product in
the US, LICENSEE shall manufacture said product substantially in the US to the extent required by applicable law, unless a waiver is obtained from the appropriate federal agency. 



 

	6.4	 Access Requirements. To the extent required by applicable law, unless a waiver is obtained from the
appropriate agency, LICENSEE shall submit an access plan to CIRM within ten (10) days following final approval of Licensed Product by the FDA. The plan must afford access to Licensed Product to Californians who have no other means to purchase
the Licensed Product (Title 17, California Code of Regulations, section 100607, Exhibit A, “Access Requirements for Products Developed by Grantees”). 



 

	6.5	 March-In Rights. To the extent required by applicable law,
unless a waiver is obtained from the appropriate agency, CIRM may request LICENSEE enter into a license agreement with respect to Licensed Product in any field of use or territory with a responsible applicant or applicants, upon terms that are
reasonable under the circumstances (Title 17, California Code of Regulations, section 100610, Exhibit A, “March-In Rights”). 



ARTICLE 7. TERMINATION OR EXPIRATION OF THE AGREEMENT 
  

	7.1	 Termination by UNIVERSITY. 



(a)         If LICENSEE fails to perform or violates any material term of this Agreement, then
UNIVERSITY may give written notice of default (“Notice of Default”) to LICENSEE. If LICENSEE fails to cure the default or fails to provide UNIVERSITY with a reasonable plan of action to cure such default, UNIVERSITY may terminate this
Agreement and the license granted herein by a second written notice (“Notice of Termination”) to LICENSEE. If a Notice of Termination is sent to LICENSEE, this Agreement shall automatically terminate on the effective date of that notice.
Termination 

  
 20 

			
	Eff. 4/18/12	  	OAL FINAL














 
shall not relieve LICENSEE of its obligation to pay any fees owed at the time of termination and shall not impair any accrued right of UNIVERSITY. During the term of any such Notice of Default or
period to cure, to the extent the default at issue is a failure to pay past or ongoing Patent Costs as provided for under this Agreement, UNIVERSITY shall have no obligation to incur any new Patent Costs under this Agreement and shall have no
obligation to further prosecute Patent Rights or file any new patents under Patent Rights. 

(b)         This Agreement will terminate immediately, without the obligation to provide sixty
(60) days’ notice as set forth in Paragraph 7.l(a), if LICENSEE files a claim asserting that any portion of UNIVERSITY’s Patent Rights is invalid or unenforceable where the filing is by the LICENSEE, a third party on behalf of
the LICENSEE, or a third party at the written urging of the LICENSEE. 
 (c)         This Agreement
shall automatically terminate without the obligation to provide sixty (60) days’ notice as set forth in Paragraph 7.1(a) upon the filing of a petition for relief under the United States Bankruptcy Code by the LICENSEE as a debtor or
alleged debtor. 
  

	7.2	 Termination by LICENSEE. 



(a)         LICENSEE shall have the right at any time and for any reason to terminate this Agreement
upon a ninety (90) day written notice to UNIVERSITY. Said notice shall state LICENSEE’s reason for terminating this Agreement. 

(b)        Any termination under Paragraph 7.2(a) shall not relieve LICENSEE of any obligation or
liability accrued under this Agreement prior to termination or rescind any payment made to UNIVERSITY or action by LICENSEE prior to the time termination becomes effective. Termination shall not affect in any manner any rights of UNIVERSITY arising
under this Agreement prior to termination. 
  

	7.3	 Term. Unless otherwise terminated by operation of law or by acts of the parties in accordance with the
terms of this Agreement, this Agreement will be in force throughout the Term, and will expire upon the completion of the Term. Upon the natural termination of the Term, the licenses granted hereunder shall be deemed to be fully paid up, perpetual
and irrevocable. 


  

	7.4	 Survival on Termination or Expiration. The following paragraphs and articles shall survive the
termination or expiration of this Agreement:

	7.5	 Disposition of Licensed Products on Hand. Upon termination of this Agreement, LICENSEE may dispose of
all previously made or partially made Licensed Product within a period of one hundred and eighty (180) days of the effective date of such termination provided that the sale of such Licensed Product by LICENSEE, its Sublicensees, or Affiliates
shall be subject to the terms of this Agreement, including but not limited to the rendering of reports and payment of royalties required under this Agreement. 



ARTICLE 8. LIMITED WARRANTY AND INDEMNIFICATION 
  

	8.1	 Limited Warranty. 



(a)         UNIVERSITY warrants that it has the lawful right to grant this license. This warranty does
not include Patent Rights to the extent assigned, or otherwise licensed, by UNIVERSITY’s inventors to third parties. 

(b)         The license granted herein is provided “AS IS” and without WARRANTY OF

 EXHIBIT A 

TITLE 17, CALIFORNIA CODE OF REGULATIONS 












 § 100607. Access Requirements for Products Developed by Grantees. 

(a)        A Grantee, a Collaborator or an Exclusive Licensee that is commercializing a Drug, as
defined in Title 17, California Code of Regulations, section 100601, subdivision (i), that resulted in whole or in part from CIRM-Funded Research must submit a plan to afford access to such a Drug to Californians who have no other means to purchase
the Drug. As used in this section, “no other means” means Californians who are not covered by a prescription drug benefit provided by any third-party payer (private or public) covering the particular Drug, and whose family incomes are
below 300 percent of the federal poverty level. The access plan must be consistent with industry standards at the time of commercialization accounting for the size of the market for the Drug and the resources of the Grantee, the Collaborator or
its Exclusive Licensee. Grantees, Collaborators and/or their Exclusive Licensees shall have the burden of establishing that the proposed access plan satisfies the requirements of this Section. 

(b)        A Grantee, a Collaborator or an Exclusive Licensee that commercializes a Drug must submit
the access plan described in subdivision (a) of this regulation to CIRM within 10 business days following final approval of the Drug by the federal Food and Drug Administration, unless, within that timeframe, the Grantee, Collaborator or
Exclusive Licensee seeks an extension from CIRM. If CIRM grants an extension, the access plan must be submitted no later than 30 business days following final approval of the Drug by the federal Food and Drug Administration. 

(c)        The access plan shall be subject to the approval of CIRM after a public hearing conducted
by CIRM that provides for receipt of public comment. CIRM may adopt appropriate procedures to protect proprietary information submitted by Grantees, Collaborators and Exclusive Licensees in connection with said public hearing. Approval shall not be
unreasonably 

  
 1 

			
	Eff. 4/18/12	  	OAL FINAL














 
withheld. Overall, CIRM shall not require that proposed Access plans exceed industry standards for such plans at the time of commercialization in California. 

(d)        Access plans approved hereunder shall make Grantees, Collaborators and Exclusive Licensees
that commercialize a Drug responsible only for providing the Drug itself. Nothing herein shall require the Grantee, Collaborator or Exclusive Licensee to be responsible for any costs of administering the Drug nor for any associate costs of medical
procedures or protocols for the Drug therapy, nor for any costs for attendant care. 

(e)        The Independent Citizens Oversight Committee (“ICOC”) may waive the requirement
in subdivision (a) of this section if the ICOC determines, after a public hearing, that in the absence of the waiver, development and broad delivery of the Drug will be unreasonably hindered or that the waiver will provide significant benefits
that equal or exceed the benefits that would otherwise flow to the state pursuant to subdivision (a) of this section. To invoke this waiver provision, a Grantee, Collaborator or Exclusive Licensee must deliver a written request to the Chair of
the ICOC within 10 business days following final approval of the Drug by the federal Food and Drug Administration, unless the Chair of the ICOC agrees to an extension. The request must be accompanied by materials describing how development and broad
delivery of the Drug will be unreasonably hindered by compliance with subdivision (a) of this section, and/or how the waiver will provide significant benefits that equal or exceed the benefits that would otherwise flow to the state pursuant to
subdivision (a) of this section. The request shall be posted on CIRM’s website no fewer than ten (10) business days prior to the ICOC’s consideration. The ICOC may meet in closed session to review confidential or proprietary
material, or other material as allowed by Health and Safety Code section 125290.30, subdivision (d).

	Eff. 4/18/12	  	OAL FINAL














 (f)        A Grantee, Collaborator, or an Exclusive
Licensee that is commercializing the Drug must provide a Drug, that resulted in whole or in part from CIRM-Funded Research, at a price as provided in the California Discount Prescription Drug Program (commencing with California Health and Safety
Code section 130500) (or a successor statewide prescription drug discount program) to eligible Californians under said program. 

(g)        A Grantee, Collaborator or its Exclusive Licensee that is commercializing the Drug must
sell a Drug, that resulted in whole or in part from CIRM-Funded Research, and which is purchased in California with Public Funds (as defined in Title 17, California Code of Regulations, section 100601, subdivision (cc)) at any benchmark price
described in the California Discount Prescription Drug Program or a successor statewide prescription drug discount program. 

(h)        This regulation is not intended, and this-regulation shall not be construed, to preempt or
prevent any other requirement under state or federal law or regulation, or agreement or contract, that would result in selling a Drug at a lower price than provided hereunder. Note: Authority cited: Article XXXV, California Constitution; and
Section 125290.40(j), Health and Safety Code. 
 Reference: Sections 125290.30 and 125290.80, Health and Safety Code.

 § 100610. March-In Rights. 

 

	(a)	 CIRM may request that a Grantee, Collaborator or an Exclusive Licensee enter into a nonexclusive, partially
exclusive, or Exclusive License Agreement with respect to a CIRM-Funded Invention or CIRM-Funded Technology, in any field of use or territory with a responsible applicant or applicants, upon terms that are reasonable under the circumstances.



  

	(b)	 If a Grantee, Collaborator or an Exclusive Licensee refuses CIRM’s request to enter into a License
Agreement to a CIRM-Funded Invention or CIRM-Funded Technology as provided by this regulation, CIRM shall have the right to enter into such a license with an applicant on behalf of the Grantee or its Exclusive Licensee
(march-in) if: 


  

	 	(1)	 the Grantee, Collaborator or an Exclusive Licensee has not made reasonable efforts to achieve practical
application of a CIRM-Funded Invention and/or CIRM-Funded Technology, as applicable; 


  

	 	(2)	 the Grantee, Collaborator or an Exclusive Licensee have failed to provide or comply with a plan for access to a
Drug in accordance with Title 17, California Code of Regulations, section 100607; 


  

	 	(3)	 the Grantee, Collaborator or Exclusive Licensee has unreasonably failed to use a CIRM-Funded Invention or CIRM-
Funded Technology to alleviate public health and safety needs that constitute a public health emergency as declared by the Governor. 


  

	(c)	 One consideration in taking the action described in subdivision (b) of this regulation will be whether
doing so will impinge on the Grantee’s, Collaborator’s or Exclusive Licensee’s academic freedoms. 


  

	(d)	 CIRM will promptly notify a Grantee, Collaborator or an Exclusive Licensee of any adverse determination under
this provision and the basis therefore, as well as its intention to exercise march-in rights ( “March-In Notice”). 



 

	(e)	 CIRM will not exercise its march-in rights if the Grantee, Collaborator
or an Exclusive Licensee promptly takes action to cure the deficiency and such deficiency is cured sooner than one year from the date of the March-In Notice (or longer period by mutual agreement). With respect
to a deficiency described in subdivision (b)(3) of this regulation, however, CIRM may exercise such right at any time in the event of a public health or safety emergency declared by the Governor and where CIRM finds that exercise of march-in rights is likely to alleviate the circumstances or conditions that give rise to the emergency declaration. 


  

	(f)	 Within thirty (30) days of the date CIRM issues a March-In Notice,
the subject Grantee may appeal CIRM’s decision to the ICOC by notifying the President of CIRM in writing of its intent to appeal CIRM’s decision. Within sixty (60) days of the March-In Notice
date, the subject Grantee must submit a written statement of the reasons for the appeal and any supporting materials it wishes to have considered by the ICOC. Absent 















	 	 
extraordinary circumstances, the ICOC shall render a final determination on the appeal within one hundred twenty (120) days of the March-In Notice. In
cases where an appeal is filed, CIRM shall not effect a march-in unless and until the ICOC renders a final determination on the appeal. The ICOC may reverse the decision of the CIRM to exercise march-in rights under this regulation for any reason. 


  

	(g)	 Unless provided otherwise by CIRM, any applicant to receive a License or Assignment pursuant to this regulation
will be bound by this Chapter as if it were an original Grantee recipient of the funding that resulted in the applicable CIRM-Funded Invention or CIRM-Funded Technology.

 1 













 
Stock, par value $0.0001 per share (“Preferred Stock”). The Preferred Stock shall consist of three series, one of which shall be designated “Series A Preferred

B.        Preferred Stock. The following is a statement of the designations and
the powers, privileges and rights, and the qualifications, limitations or restrictions thereof in respect of each series of Preferred Stock of this Corporation. Unless otherwise indicated, references to “Sections” or
“subsections” in this Part B of Article IV refer to sections and subsections of Part B of this Article IV. 

1.        Dividends. In the event dividends are paid on any share of Common Stock, the
Corporation shall pay an additional dividend on all outstanding shares of Preferred Stock in a per share amount equal (on an as-if-converted to Common Stock basis) to
the amount paid or set aside for each share of Common Stock. Such dividends shall be payable only when, as and if declared by the Board of Directors of the Corporation. 

2.        Liquidation. 

(a)        Preferences. 

(i)        In the event of any voluntary or involuntary dissolution, liquidation or winding up of the
affairs of the Corporation (a “Liquidation Event”), after payment or provision for payment of the debts and other liabilities of the Corporation, the holders of each share of Series B-2 Preferred Stock shall be entitled to receive on a pro rata basis out of the assets of the Corporation, whether such assets are capital, surplus or earnings, an amount equal to the Liquidation Value (as set forth
in Section 2(e)) of such share, which amount shall be paid prior to and in preference of any payment made or assets distributed on the Series B Preferred Stock, the Series A Preferred Stock, the Common Stock or any other class or series of
capital stock of the Corporation. 
 (ii)        In the event of a Liquidation Event, after payment
to the holders of Series B-2 Preferred Stock of the full amounts specified in Section 2(a)(i) above, the holders of each share of Series B Preferred Stock shall be entitled to receive on a pro rata basis
out of the assets of the Corporation, whether such assets are capital, surplus or earnings, an amount equal to the Liquidation Value (as set forth in Section 2(e)) of such share, which amount shall be paid prior to and in preference of any
payment made or assets distributed on the Series A Preferred Stock, the Common Stock or any other class or series of capital stock of the Corporation. 

(iii)        In the event of a Liquidation Event, after payment to the holders of Series B Preferred
Stock of the full amounts specified in Section 2(a)(ii) above, the holders of each share of Series A Preferred Stock shall be entitled to receive on a pro rata basis out of the assets of the Corporation, whether such assets are capital, surplus
or earnings, an amount equal to 

  
 2 













 
the Liquidation Value (as set forth in Section 2(e)) of such share, which amount shall be paid prior to and in preference of any payment made or assets distributed on the Common Stock or any
other class or series of capital stock of the Corporation. 
 (b)        Partial Payment. If
upon any Liquidation Event the assets of the Corporation distributable as aforesaid among the holders of the Series B-2 Preferred Stock, the Series B Preferred Stock or the Series A Preferred Stock, as
applicable, shall be insufficient to permit the payment to them of the full preferential amounts to which they are entitled, then the entire remaining assets of the Corporation so to be distributed shall be distributed ratably among the holders of
the Series B-2 Preferred Stock, the Series B Preferred Stock or the Series A Preferred Stock, as applicable, in proportion to the sum of their respective per share Liquidation Value; provided that no payments
shall be made to holders of the Series B Preferred Stock until the holders of the Series B-2 Preferred Stock have received the full preferential amounts to which they are entitled, and no payments shall be
made to holders of the Series A Preferred Stock until the holders of the Series B Preferred Stock have received the full preferential amounts to which they are entitled. 

(c)        Remaining Assets. After payment to the holders of Preferred Stock of the amounts
set forth in Section 2(a) above, the entire remaining assets and funds of the Corporation legally available for distribution, if any, shall be distributed ratably among the holders of the Common Stock and the holders of the Preferred Stock on
an as-converted to Common Stock basis at the then applicable conversion rate, until such time as each share of Preferred Stock has received an aggregate distribution of three times (3x) the applicable
Liquidation Value for such share of Preferred Stock (as adjusted for all stock splits, stock dividends, consolidations, recapitalizations and reorganizations) (which aggregate distribution amount shall include (i) distributions made pursuant to
Section 2(a) above and (ii) distributions made pursuant to this Section 2(c)), at which point no further payments shall be made to holders of the Preferred Stock by reason thereof and any remaining assets of the Corporation shall be
distributed ratably among the holders of the Common Stock. 
 (d)        Deemed Conversion.
Notwithstanding the above Sections 2(a), (b) and (c), for purposes of determining the amount each holder of shares of Preferred Stock is entitled to receive with respect to a Liquidation Event, each such holder of shares of Preferred Stock shall be
deemed to have converted (regardless of whether such holder actually converted) such holder’s shares of Preferred Stock into shares of Common Stock immediately prior to the Liquidation Event if, as a result of an actual conversion, such holder
would receive, in the aggregate, an amount greater than the amount that would be distributed to such holder if such holder did not convert such Preferred Stock into shares of Common Stock. If any such holder shall be deemed to have converted shares
of Preferred Stock into Common Stock pursuant to this Section 2(d), then such holder shall not be entitled to receive any distribution that would otherwise be made to holders of Preferred Stock. 

(e)        Liquidation Value. The “Liquidation Value” per share of Series A
Preferred Stock as of any particular date shall be the sum of (A) $0.25 (as adjusted for all stock splits, stock dividends, consolidations, recapitalizations and reorganizations) plus (B) all declared but unpaid dividends as of the date the
Liquidation Value of such share is determined. The Liquidation Value per share of Series B Preferred Stock as of any particular date shall be the 

  
 3 













 
sum of (A) $0.45 (as adjusted for all stock splits, stock dividends, consolidations, recapitalizations and reorganizations) plus (B) all declared but unpaid dividends as of the date the
Liquidation Value of such share is determined. The Liquidation Value per share of Series B-2 Preferred Stock as of any particular date shall be the sum of (A) $0.45 (as adjusted for all stock splits, stock
dividends, consolidations, recapitalizations and reorganizations) plus (B) all declared but unpaid dividends as of the date the Liquidation Value of such share is determined. The Liquidation Value as it applies to each series of Preferred Stock
is sometimes referred to herein as the “Liquidation Value.” 

(f)        Deemed Liquidation Events. 

(i)        Definition. For purposes of this Section 2, a Liquidation Event shall be
deemed to be occasioned by, or to include, the following (each, a “Deemed Liquidation Event”) unless the Requisite Holders elect otherwise: 

(a)        a merger or consolidation in which 

(i)        the Corporation is a constituent party, or 

(ii)        a Subsidiary of the Corporation is a constituent party and the Corporation issues shares
of its capital stock pursuant to such merger or consolidation, except any such merger or consolidation involving the Corporation or a Subsidiary in which the shares of capital stock of the Corporation outstanding immediately prior to such merger or
consolidation continue to represent, or are converted into or exchanged for shares of capital stock that represent, immediately following such merger or consolidation, at least a majority, by voting power, of the capital stock of (1) the
surviving or resulting corporation or (2) if the surviving or resulting corporation is a wholly owned subsidiary of another corporation immediately following such merger or consolidation, the parent corporation of such surviving or resulting
corporation (provided that, for the purpose of this Section 2(f)(i)(a), all shares of Common Stock issuable upon exercise of stock options of the Corporation outstanding immediately prior to such merger or consolidation or upon conversion of
convertible securities of the Corporation outstanding immediately prior to such merger or consolidation shall be deemed to be outstanding immediately prior to such merger or consolidation and, if applicable, converted or exchanged in such merger or
consolidation on the same terms as the actual outstanding shares of Common Stock are converted or exchanged); provided, that the preceding exception shall not apply (and such merger or consolidation shall be a Deemed Liquidation Event) to a merger
or consolidation involving the Corporation or a Subsidiary where such transaction is entered into with an entity that has its securities registered under the Securities Act of 1933, as amended, listed on a nationally recognized stock exchange or
market system, including without limitation The NASDAQ Global Select Market, The NASDAQ Global Market or The NASDAQ Capital Market, or quoted on an automated quotation system (including the Pink Sheets and the OTC Bulletin Board) or by a recognized
securities dealer; or 
 (b)        the sale, lease, transfer, exclusive license or other
disposition, in a single transaction or series of related transactions, by the Corporation or any Subsidiary of the Corporation of all or substantially all the assets of the Corporation and its Subsidiaries taken as a whole, or the sale or
disposition (whether by merger or otherwise) of one or more Subsidiaries of 

  
 4 













 
the Corporation if substantially all of the assets of the Corporation and its Subsidiaries taken as a whole are held by such Subsidiary or Subsidiaries, except where such sale, lease, transfer,
exclusive license or other disposition is to a wholly owned Subsidiary of the Corporation. 

(ii)        Effecting a Deemed Liquidation Event. 

(a)        The Corporation shall not have the power to effect a Deemed Liquidation Event referred to
in Section 2(f)(i)(a) unless the agreement or plan of merger or consolidation for such transaction provides that the consideration payable to the stockholders of the Corporation shall be allocated among the holders of capital stock of the
Corporation in accordance with Sections 2(a), (b), (c) and (d). 
 (b)        In the event of a
Deemed Liquidation Event referred to in Section 2(f)(i)(a)(ii) or 2(f)(i)(b), if the Corporation does not effect a dissolution of the Corporation under the General Corporation Law within 90 days after such Deemed Liquidation Event, then
(i) the Corporation shall send a written notice to each holder of Preferred Stock no later than the 90th day after the Deemed Liquidation Event advising such holders of their right (and the requirements to be met to secure such right) pursuant
to the terms of the following clause (ii) to require the redemption of such shares of Preferred Stock, and (iii) if the holders of at least a majority of the then outstanding shares of Preferred Stock so request in a written instrument
delivered to the Corporation not later than 120 days after such Deemed Liquidation Event, the Corporation shall use the consideration received by the Corporation for such Deemed Liquidation Event (net of any retained liabilities associated with the
assets sold or technology licensed, as determined in good faith by the Board of Directors of the Corporation), together with any other assets of the Corporation available for distribution to its stockholders (the “Available
Proceeds”), to the extent legally available therefor, on the 150th day after such Deemed Liquidation Event, to redeem all outstanding shares of Preferred Stock at a price per share equal to the applicable Liquidation
Value. Notwithstanding the foregoing, in the event of a redemption pursuant to the preceding sentence, if the Available Proceeds are not sufficient to redeem all outstanding shares of Preferred Stock, the Corporation shall first redeem a pro rata
portion of shares of Series A Preferred Stock, Series B Preferred Stock and Series B-2 Preferred Stock in accordance with the liquidation preferences set forth in Sections 2(a) and (b) to the fullest
extent of such Available Proceeds, and shall redeem the remaining shares to have been redeemed as soon as practicable after the Corporation has funds legally available therefor. Prior to the distribution or redemption provided for in this
Section 2(f)(ii)(b), the Corporation shall not expend or dissipate the consideration received for such Deemed Liquidation Event, except to discharge expenses incurred in connection with such Deemed Liquidation Event or in the ordinary course of
business. 
 (iii)        Notice. The Corporation shall give each holder of record of
Preferred Stock written notice of such impending event described in Section 2(f)(i) not later than twenty (20) calendar days prior to the stockholders meeting called to approve such transaction, or twenty (20) calendar days prior to
the closing of such transaction, whichever is earlier, and shall also notify such holders in writing of the final approval of such transaction. The first of such notices shall describe the material terms and conditions of the impending transaction
and the provisions of Section 2, and the Corporation shall thereafter give such holders prompt notice of any material changes. The transaction shall in no event take place sooner than twenty (20)


  
 5 













 
calendar days after the Corporation has given the first notice provided for herein or sooner than ten (10) calendar days after the Corporation has given notice of any material changes
provided for herein. Notwithstanding anything to the contrary in subsection 2(f)(ii) or 2(f)(iii), the periods set forth in subsection 2(f)(ii) and 2(f)(iii) may be shortened and/or notice may be waived upon the Corporation’s receipt of written
consent of the Requisite Holders. 
 3.        Redemption. The Corporation shall not be
obligated to, and shall not have the right to, call or redeem any shares of the Preferred Stock, except in accordance with Section 2(f)(ii)(b) above. 

4.        Voting Rights; Directors. 

(a)        Generally. On all matters to come before the stockholders, the Preferred Stock
shall have that number of votes per share (rounded up to the nearest whole share) equivalent to the number of shares of Common Stock into which such share of Preferred Stock is then convertible determined by reference to the applicable Conversion
Price in effect at the record date of the determination of the holders of the shares entitled to vote or, if no such record date is established, at the date such vote is taken or any written consent of stockholders is first solicited. Each holder of
shares of Common Stock shall be entitled to one (1) vote for each share thereof held. Except as otherwise provided by law or this Amended and Restated Certificate of Incorporation, the holders of Preferred Stock shall vote together with the
holders of the outstanding shares of Common Stock, and not as a separate class or series. 

(b)        Directors. 

(i)        The authorized number of directors shall be seven (7) until this provision is amended
in accordance with the terms of this Amended and Restated Certificate of Incorporation. The holders of the outstanding shares of Series A Preferred Stock, voting as a separate class and to the exclusion of all other classes of capital stock of the
Corporation, shall be entitled to elect one (1) member of the Board of Directors (the “Series A Director”). The holders of the outstanding shares of Series B-2
Preferred Stock, voting as a separate class and to the exclusion of all other classes of capital stock of the Corporation, shall be entitled to elect two (2) members of the Board of Directors (the “Series B-2 Directors”, together with the Series A Director, the “Preferred Directors”). The holders of the outstanding shares of Common Stock, voting as a
separate class and to the exclusion of all other classes of capital stock of the Corporation, shall be entitled to elect three (3) members of the Board of Directors (the “Common Directors”). The holders of
the outstanding shares of Preferred Stock and Common Stock, voting together as a single class, shall be entitled to elect the remaining member of the Board of Directors (the “General Director”). For
administrative convenience, the initial Series B-2 Directors may also be appointed by the Board of Directors in connection with the approval of the initial issuance of Series
B-2 Preferred Stock without a separate action by the holders of the Series B-2 Preferred Stock. 

(ii)        In the case of any vacancy in the office of a director occurring among the Preferred
Directors or the Common Directors, by the affirmative vote of the holders of a majority of the shares of the class or classes entitled to vote on the election of the Preferred Directors or Common Directors, as the case may be, such holders shall
elect a successor or 

  
 6 













 
successors to hold the office for the unexpired term of the director or directors whose place or places shall be vacant. In the case of any vacancy in the office of a General Director, by the
affirmative vote of the holders of a majority of the shares of Preferred Stock and Common Stock, voting together as a single class, such holders shall elect a successor or successors to hold the office for the unexpired term of the director or
directors whose place or places shall be vacant. Any director may be removed during the aforesaid term of office, whether with or without cause, only by the affirmative vote of the holders of a majority of the shares eligible to vote in an election
for the seat occupied by that director (e.g., in order to remove a Series A Director, the holders of a majority of the shares of Series A Preferred Stock, voting as a separate class and to the exclusion of all other classes of capital stock of the
Corporation, must so vote). 
 (c)        Protective Provisions. In addition to voting
rights provided by law, so long as any shares of Preferred Stock shall be outstanding (as adjusted for all stock splits, stock dividends, consolidations, recapitalizations and reorganizations), the Corporation shall not, without the consent of the
holders of at least a majority of the outstanding shares of Preferred Stock, given in person or by proxy, either in writing or by vote at a meeting called for that purpose at which the holders of the Preferred Stock shall vote together as a separate
class and to the exclusion of all other classes of capital stock of the Corporation: 

(i)        declare or pay any dividends on any capital stock of the Corporation; 

(ii)        redeem or repurchase capital stock of the Corporation except in connection with the
repurchase of shares of Common Stock issued to or held by employees, consultants, officers and directors upon termination of their employment or services pursuant to agreements providing for the right of said repurchase, which agreements were
authorized by the Board of Directors; 
 (iii)        take any action which would result in a
Liquidation Event or a Deemed Liquidation Event; 
 (iv)        increase or decrease the total
number of authorized members of the Board of Directors; 
 (v)        authorize, create or issue
(whether by merger, consolidation, reclassification, amendment of this Amended and Restated Certificate of Incorporation, sale or otherwise) shares of any class or series of stock not authorized herein having rights, preferences or privileges
superior to or on parity with the Series B-2 Preferred Stock; or 

(vi)        take any action to amend or waive any provision of this Amended and Restated Certificate
of Incorporation or the Company’s Bylaws. 
 5.        Conversion. The rights of the
holders of shares of Preferred Stock to convert such shares into shares of Common Stock (as defined in Section 5(h) below) of the Corporation (the “Conversion Rights”), and the terms and conditions of such
conversion, shall be as follows: 

  
 7 













 (a)        Right to Convert; Automatic
Conversion. 
 (i)        Each share of the Preferred Stock shall be convertible, at the option
of the holder, in each case at the office of the Corporation or any transfer agent for the Preferred Stock or the Common Stock, into that number of the fully paid and nonassessable shares of Common Stock determined in accordance with the provisions
of Section 5(b) below. 
 (ii)        Before any holder of Preferred Stock shall be entitled
to convert the same into shares of Common Stock, the holder shall surrender the certificate(s) therefor, duly endorsed, at the office of the Corporation or of any transfer agent for the Preferred Stock and shall give written notice to the
Corporation at such office that the holder elects to convert the same (except that no such written notice of election to convert shall be necessary in the event of an automatic conversion pursuant to Section 5(a)(iv) hereof). The Corporation
shall, as soon as practicable thereafter, issue and deliver at such office to such holder of Preferred Stock certificate(s) for the number of shares of Common Stock to which such holder shall be entitled as aforesaid. Such conversion shall be deemed
to have been made immediately prior to the close of business on the date of such surrender of the shares of Preferred Stock to be converted; except that in the case of an automatic conversion pursuant to Sections 5(a)(iv)(A) and/or 5(a)(v)(A)
hereof, such conversion shall be deemed to have been made immediately prior to the closing of the offering referred to in Sections 5(a)(iv)(A) and/or 5(a)(v)(A), or in the case of an automatic conversion pursuant to Sections 5(a)(iv)(B) and/or
5(a)(v)(B) hereof, immediately prior to the close of business on the date of the election referred to in Sections 5(a)(iv)(B) and/or 5(a)(v)(B), and the Person or Persons entitled to receive the shares of Common Stock issuable upon such conversion
shall be treated for all purposes as the record holder or holders of such shares of Common Stock on such date. If the conversion is in connection with an underwritten public offering of securities registered pursuant to the Securities Act, the
conversion may, at the option of any holder tendering Preferred Stock for conversion, be conditioned upon the closing with the underwriters of the sale of securities pursuant to such offering, in which event any Persons entitled to receive Common
Stock upon conversion of Preferred Stock shall not be deemed to have converted such Preferred Stock until immediately prior to the closing of such sale of securities. 

(iii)        The Corporation shall, as soon as practicable after the surrender of the certificate or
certificates evidencing shares of Preferred Stock for conversion at the office of the Corporation or the transfer agent for the Preferred Stock or the Common Stock, issue to each holder of such shares, or its nominee or nominees, a certificate or
certificates evidencing the number of shares of Common Stock (and any other securities and property) to which it shall be entitled and, in the event that only a part of the shares evidenced by such certificate or certificates are converted, a
certificate evidencing the number of shares of Preferred Stock which are not converted. Such conversion shall be deemed to have been made immediately prior to the close of business on the date of such surrender of the shares of Preferred Stock to be
converted, except that in the case of an automatic conversion pursuant to Sections 5(a)(iv)(A) and/or 5(a)(v)(A) hereof, such conversion shall be deemed to have been made immediately prior to the closing of the offering referred to in Sections
5(a)(iv)(A) and/or 5(a)(v)(A), or in the case of an automatic conversion pursuant to Sections 5(a)(iv)(B) and/or 5(a)(v)(B) hereof, immediately prior to the close of business on the date of the election referred to in Sections 5(a)(iv)(B) and/or
5(a)(v)(B), and the Person or Persons entitled to receive the shares of Common Stock issuable 

  
 8 













 
upon such conversion shall be treated for all purposes as the record holder or holders of such shares of Common Stock at such date and shall, with respect to such shares, have only those rights
of a holder of Common Stock of the Corporation. 
 (iv)        Each share of Series A Preferred
Stock then outstanding shall be automatically converted into that number of fully paid and nonassessable shares of Common Stock determined in accordance with the provisions of Section 5(b) below upon the earlier of (A) the close of
business of the day immediately preceding the effective date of the Corporation’s registration statement filed in connection with a Qualified Public Offering (as defined in Section 6 below) or (B) the consent of the holders of at
least a majority of the outstanding shares of Series A Preferred Stock voting or consenting together as a separate class, given in person or by proxy, either in writing or by vote at a meeting called for that purpose at which the holders of Series A
Preferred Stock shall vote together as a separate class. 
 (v)        Each share of Series B
Preferred Stock and Series B-2 Preferred Stock then outstanding shall be automatically converted into that number of fully paid and nonassessable shares of Common Stock determined in accordance with the
provisions of Section 5(b) below upon the earlier of (A) the close of business of the day immediately preceding the effective date of the Corporation’s registration statement filed in connection with a Qualified Public Offering (as
defined in Section 6 below) or (B) the consent of the holders of at least a majority of the outstanding shares of Series B Preferred Stock and Series B-2 Preferred Stock, voting or consenting
together as a single class, given in person or by proxy, either in writing or by vote at a meeting called for that purpose at which the holders of Series B Preferred Stock and Series B-2 Preferred Stock shall
vote together as a single class. 
 (vi)        No fractional shares of Common Stock shall be
issued upon conversion of the Preferred Stock. In lieu of any fractional shares to which the holder would otherwise be entitled, the Corporation shall pay cash equal to such fraction multiplied by the fair market value of a share of Common Stock as
determined in good faith by the Board of Directors of the Corporation. Whether or not fractional shares would be issuable upon such conversion shall be determined on the basis of the total number of shares of Preferred Stock the holder is at the
time converting into Common Stock and the aggregate number of shares of Common Stock issuable upon such conversion. 

(b)        Conversion of Preferred Stock. The Series A Preferred Stock shall be convertible
into the number of shares of Common Stock which results from dividing the Conversion Price (as defined herein) per share in effect at the time into $0.25 per share of Series A Preferred Stock being converted. The Series B Preferred Stock shall be
convertible into the number of shares of Common Stock which results from dividing the Conversion Price per share in effect at the time into $0.45 per share of Series B Preferred Stock being converted. The Series
B-2 Preferred Stock shall be convertible into the number of shares of Common Stock which results from dividing the Conversion Price per share in effect at the time into $0.45 per share of Series B-2 Preferred Stock being converted. 
 (c)        Conversion
Price. The conversion price per share for the Series A Preferred Stock shall initially be $0.25 (the “Series A Conversion Price”) and shall be subject to adjustment from time to time as provided herein. The conversion
price per share for the Series B 

  
 9 













 
Preferred Stock shall initially be $0.45 (the “Series B Conversion Price”) and shall be subject to adjustment from time to time as provided herein. The conversion price
per share for the Series B-2 Preferred Stock shall initially be $0.45 (the “Series B-2 Conversion Price”) and shall be subject to adjustment from
time to time as provided herein. Each of the Series A Conversion Price, the Series B Conversion Price and the Series B-2 Conversion Price are sometimes referred to herein as the “Conversion
Price”. 
 (d)        Adjustment for Stock Splits and Combinations. If
outstanding shares of the Common Stock of the Corporation shall be subdivided into a greater number of shares, or a dividend in Common Stock or other securities of the Corporation convertible into or exchangeable for Common Stock, shall be paid in
respect to the Common Stock of the Corporation, the applicable Conversion Price in effect immediately prior to such subdivision or at the record date of such dividend shall be proportionately reduced, and conversely, if outstanding shares of the
Common Stock of the Corporation shall be combined into a smaller number of shares, the applicable Conversion Price in effect immediately prior to such combination shall be proportionately increased. 

Any adjustment to a Conversion Price under this Section 5(d) shall become effective at the close of business on the date the subdivision
or combination referred to herein becomes effective. 
 (e)        Reorganizations, Mergers,
Consolidations or Reclassifications. In the event of any capital reorganization, any reclassification of the Common Stock (other than a change in par value or as a result of a stock dividend, subdivision,
split-up or combination of shares), the consolidation or merger of the Corporation with or into another Person (excluding a consolidation or merger described in Section 2(f)(i)(a) of this Article IV)
(collectively referred to hereinafter as “Reorganizations”), the holders of the Preferred Stock shall thereafter be entitled to receive, and provision shall be made therefor in any agreement relating to a
Reorganization, upon conversion of the Preferred Stock the kind and number of shares of Common Stock or other securities or property (including cash) of the Corporation, or other corporation resulting from such consolidation or surviving such merger
to which a holder of the number of shares of the Common Stock of the Corporation which the applicable series of Preferred Stock entitled the holder thereof to convert to immediately prior to such Reorganization would have been entitled to receive
with respect to such Reorganization; and in any such case appropriate adjustment shall be made in the application of the provisions herein set forth with respect to the rights and interests thereafter of the holders of the Preferred Stock to the end
that the provisions set forth herein (including the specified changes and other adjustments to the applicable Conversion Price) shall thereafter be applicable, as nearly as reasonably may be, in relation to any shares, other securities or property
thereafter receivable upon conversion of the Preferred Stock. The provisions of this Section 5(e) shall similarly apply to successive Reorganizations. 

(f)        Sale of Additional Shares. 

(i)        If at any time or from time to time following the date of the initial issuance of shares
of Series B-2 Preferred Stock, the Corporation shall issue or sell (or is deemed to have issued or sold) Additional Shares of Common Stock other than as a dividend or other distribution on any class of stock
and other than as a subdivision or combination of shares of 

  
 10 













 
Common Stock as provided in Section 5(d) above, for a consideration per share less than the then existing Series B-2 Conversion Price, then, and in
each such case, the then existing Series B-2 Conversion Price shall be reduced, as of the opening of business on the date of such issuance or sale, to the consideration per share received by the Corporation
for such issue or deemed issue of the Additional Shares of Common Stock; provided that if such issuance or deemed issuance was without consideration, then the Corporation shall be deemed to have received an aggregate of $0.001 of consideration for
all such Additional Shares of Common Stock issued or deemed to be issued; provided, however, that solely with respect to any shares of Series B-2 Preferred Stock issued in exchange for shares of Series B
Preferred Stock, the Series B-2 Conversion Price shall not be reduced pursuant to the foregoing, but shall instead be reduced in the manner described in Section 5(f)(ii) below (mutatis mutandis). 

(ii)        If at any time or from time to time following the date of the initial issuance of shares
of Series B-2 Preferred Stock, the Corporation shall issue or sell (or is deemed to have issued or sold) Additional Shares of Common Stock other than as a dividend or other distribution on any class of stock
and other than as a subdivision or combination of shares of Common Stock as provided in Section 5(d) above, for a consideration per share less than the then existing Series B Conversion Price, then, and in each such case, the then existing
Series B Conversion Price shall be reduced, as of the opening of business on the date of such issuance or sale, to a price determined by multiplying the Series B Conversion Price by a fraction, the numerator of which shall be the number of shares of
Common Stock outstanding immediately prior to such issuance (including shares of Common Stock issuable upon conversion of the Series B Preferred Stock and the number of shares of Common Stock which could be obtained through the exercise or
conversion of all other rights, options and convertible securities outstanding on the date immediately prior to such issuance) plus the number of shares of Common Stock that the aggregate consideration received by the Corporation for such issuance
would purchase at the then existing Series B Conversion Price; and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including shares of Common Stock issuable upon conversion of
the Series B Preferred Stock and the number of shares of Common Stock which could be obtained through the exercise or conversion of all other rights, options and convertible securities outstanding on the date immediately prior to such issuance) plus
the number of shares of Additional Shares of Common Stock actually issued in such issuance. 

(iii)        If at any time or from time to time following the date of the initial issuance of shares
of Series B-2 Preferred Stock, the Corporation shall issue or sell (or is deemed to have issued or sold) Additional Shares of Common Stock other than as a dividend or other distribution on any class of stock
and other than as a subdivision or combination of shares of Common Stock as provided in Section 5(d) above, for a consideration per share less than the then existing Series A Conversion Price, then, and in each such case, the then existing
Series A Conversion Price shall be reduced, as of the opening of business on the date of such issuance or sale, to a price determined by multiplying the Series A Conversion Price by a fraction, the numerator of which shall be the number of shares of
Common Stock outstanding immediately prior to such issuance (including shares of Common Stock issuable upon conversion of the Series A Preferred Stock and the number of shares of Common Stock which could be obtained through the exercise or
conversion of all other rights, options and convertible securities outstanding on the date immediately prior to such issuance) plus the number of shares of Common Stock that the 

  
 11 













 
aggregate consideration received by the Corporation for such issuance would purchase at the then existing Series A Conversion Price; and the denominator of which shall be the number of shares of
Common Stock outstanding immediately prior to such issuance (including shares of Common Stock issuable upon conversion of the Series A Preferred Stock and the number of shares of Common Stock which could be obtained through the exercise or
conversion of all other rights, options and convertible securities outstanding on the date immediately prior to such issuance) plus the number of shares of Additional Shares of Common Stock actually issued in such issuance. 

(iv)        For the purpose of making any adjustment in the applicable Conversion Price, or number of
shares of Common Stock issuable upon conversion of the applicable series of Preferred Stock, as provided above, the consideration received by the Corporation for any issue or sale of securities shall: 

(a)        To the extent it consists of cash, be computed at the net amount of cash received by the
Corporation after deduction of any expenses payable directly or indirectly by the Corporation and any underwriting or similar commissions, compensations, discounts or concessions paid or allowed by the Corporation in connection with such issue or
sale; 
 (b)        To the extent it consists of property other than cash, the consideration other
than cash shall be computed at the fair market value thereof as determined in good faith by the Board of Directors, at or about, but as of, the date of the adoption of the resolution specifically authorizing such issuance or sale, irrespective of
any accounting treatment thereof; provided, however, that such fair market value as determined by the Board of Directors, when added to any cash consideration received in connection with such issuance or sale, shall not exceed the aggregate market
price of the Additional Shares of Common Stock being issued, as of the date of the adoption of such resolution; and 

(c)        If Additional Shares of Common Stock, Convertible Securities (as defined below) or Rights
(as defined below) are issued or sold together with other stock or securities or other assets of the Corporation for consideration which covers both, the consideration received for the Additional Shares of Common Stock, Convertible Securities or
Rights shall be computed as that portion of the consideration so received which is reasonably determined in good faith by the Board of Directors to be allocable to such Additional Shares of Common Stock, Convertible Securities or Rights. 

(v)        For the purpose of making any adjustment in the applicable Conversion Price provided in
Section 5(f) hereof, if at any time, or from time to time, the Corporation issues any stock or other securities convertible into Additional Shares of Common Stock (such stock or other securities being hereinafter referred to as
“Convertible Securities”) or issues any rights or options to purchase Additional Shares of Common Stock or Convertible Securities (such rights or options being hereinafter referred to as
“Rights”), then, and in each such case, if the Effective Conversion Price (as hereinafter defined) of such Rights or Convertible Securities shall be less than the applicable Conversion Price in effect
immediately prior to the issuance of such Rights or Convertible Securities, the Corporation shall be deemed to have issued at the time of the issuance of such Rights or Convertible Securities the maximum number of Additional Shares of Common Stock
issuable upon exercise or conversion thereof and 

  
 12 













 
to have received in consideration for the issuance of such shares an amount equal to the aggregate Effective Conversion Price of such Rights or Convertible Securities. For the purposes of this
Section 5(f)(v), “Effective Conversion Price” shall mean an amount equal to the sum of the lowest amount of consideration, if any, received or receivable by the Corporation with respect to any one
(1) Additional Share of Common Stock upon issuance of the Rights or Convertible Securities and upon their exercise or conversion, respectively. No further adjustment of the applicable Conversion Price adjusted upon the issuance of such Rights
or Convertible Securities shall be made as a result of the actual issuance of Additional Shares of Common Stock on the exercise of any such Rights or the conversion of any such Convertible Securities. If any such Rights or the conversion privilege
represented by any such Convertible Securities shall expire without having been exercised, such applicable Conversion Price, as applicable, as adjusted upon the issuance of such Rights or Convertible Securities shall be readjusted to the Conversion
Price, as applicable, which would have been in effect had such adjustment been made on the basis that the only Additional Shares of Common Stock so issued were the Additional Shares of Common Stock, if any, actually issued or sold on the exercise of
such Rights or on the conversion of such Convertible Securities, and such Additional Shares of Common Stock, if any, were issued or sold for the consideration actually received by the Corporation upon such exercise, plus the consideration, if any,
actually received by the Corporation for the granting of all such Rights, whether or not exercised, plus the consideration received for issuing or selling the Convertible Securities actually converted plus the consideration, if any, actually
received by the Corporation (other than by cancellation of liabilities or obligations evidenced by such Convertible Securities) on the conversion of such Convertible Securities. No readjustment pursuant to this subsection (f)(v) shall have the
effect of increasing the applicable Conversion Price to an amount which exceeds the lower of (a) the applicable Conversion Price on the original adjustment date and (b) the applicable Conversion Price that would have resulted from any
issuance of Additional Shares of Common Stock between the original adjustment date and such readjustment date. 

(g)        Additional Shares of Common Stock. “Additional Shares of Common
Stock” as used in this Section 5 shall mean all shares of Common Stock issued or deemed to be issued by the Corporation, whether or not subsequently reacquired or retired by the Corporation, other than: 

(i)        shares of Series B-2 Preferred Stock and warrants
to purchase shares of Series B-2 Preferred Stock issued pursuant to the Purchase Agreement; 

(ii)        shares of Common Stock issued upon the conversion of, or as a dividend or distribution
on, any shares of the Corporation’s Preferred Stock; 
 (iii)        shares of Common Stock
issued or issuable to employees or officers or directors or outside consultants or contractors of the Corporation or any Subsidiary pursuant the exercise or conversion of options, warrants or other Convertible Securities issued pursuant to a plan,
agreement or arrangement duly approved by the Board of Directors; 
 (iv)        shares of Common
Stock issued or issuable pursuant to the exercise or conversion of options, warrants or other Convertible Securities outstanding as of the date hereof; 

  
 13 













 (v)        shares of Common Stock issued pursuant
to a Qualified Public Offering; 
 (vi)        shares of Common Stock issued to effect any stock
split, stock dividend or recapitalization of the Corporation; 
 (vii)        shares of Common
Stock and/or options, warrants or other Common Stock purchase rights issued in connection with the Corporation obtaining lease financing, whether issued to a lessor, guarantor or other Person, provided that such issuance is pursuant to an agreement
or arrangement duly approved by the Board of Directors; 
 (viii)        shares of Common Stock
and/or options, warrants or other Common Stock purchase rights issued in connection with any borrowings, direct or indirect, from a bank or other financial institution by the Corporation, provided that such issuance is pursuant to an agreement or
arrangement duly approved by the Board of Directors; 
 (ix)        shares of Common Stock and/or
options, warrants or other Common Stock purchase rights issued in connection with the acquisition of all or a substantial portion of the assets or the business of another entity by the Corporation, provided that such issuance is pursuant to an
agreement or arrangement duly approved by the Board of Directors; and 
 (x)        shares of
Common Stock and/or options, warrants or other Common Stock purchase rights issued in connection with any corporate partnering transaction, strategic alliance, technology transfer or similar transaction between the Corporation and any other Person,
provided that such issuance is pursuant to an agreement or arrangement duly approved by the Board of Directors. 

(h)        Common Stock. “Common Stock” as used in this
Section 5 shall mean any shares of any class of the Corporation’s capital stock other than the Preferred Stock. The Common Stock issuable upon conversion of the Preferred Stock, however, shall be the Common Stock of the Corporation as
constituted on the date hereof, except as otherwise provided in this Section 5. 

(i)        Certificate of Adjustment. In each case of an adjustment or readjustment of the
Conversion Price or the number of shares of Common Stock or other securities issuable upon conversion of any series of Preferred Stock, the Corporation, at its expense, shall cause the Chief Financial Officer or Treasurer of the Corporation to
compute such adjustment or readjustment in accordance with this Amended and Restated Certificate of Incorporation and prepare a certificate showing such adjustment or readjustment, and shall mail such certificate, by first-class mail, postage
prepaid, to each registered holder of such Preferred Stock at the holder’s address as shown on the Corporation’s stock transfer books. The certificate shall set forth such adjustment or readjustment, showing in detail the facts upon which
such adjustment or readjustment is based, including a statement of (i) the consideration received or to be received by the Corporation for any Additional Shares of Common Stock issued or sold or deemed to have been issued or sold; (ii) the
applicable Conversion Price at the time in effect for such Preferred Stock; and (iii) the number of Additional Shares of Common Stock and the type and amount, if 

  
 14 













 
any, of other property which at the time would be received upon conversion of such Preferred Stock. Such notice may be given in advance of such adjustment or readjustment and may be included as
part of a notice required to be given pursuant to Section 5(j) below. 
 (j)        Notices
of Record Date. In the event the Corporation shall propose to take any action of the type or types requiring an adjustment to the Conversion Price of any series of Preferred Stock, or the number or character of such Preferred Stock as set forth
herein, the Corporation shall give notice to the holders of such Preferred Stock as applicable in the manner set forth in Section 5(i) above, which notice shall specify the record date, if any, with respect to any such action and the date on
which such action is to take place. Such notice shall also set forth such facts with respect thereto as shall be reasonably necessary to indicate the effect of such action (to the extent such effect may be known at the date of such notice) on the
Conversion Price and the number, kind or class of shares or other securities or property which shall be deliverable upon the occurrence of such action or deliverable upon the conversion of the Preferred Stock. In the case of any action which would
require the fixing of a record date, such notice shall be given at least ten (10) days prior to the date so fixed, and in case of all other action, such notice shall be given at least twenty (20) days prior to the taking of such proposed
action. Notwithstanding the requirements of this Section 5(j), this Section 5(j) shall not be applicable and no such notice shall be required with respect to any action that is, or has been, approved by the Requisite Holders. 

(k)        Reservation of Stock Issuable Upon Conversion. The Corporation shall at all times
reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of the shares of Preferred Stock, such number of its shares of Common Stock as shall from time to time be
sufficient to effect a conversion of all outstanding shares of Preferred Stock, and if at any time the number of authorized but unissued shares of Common Stock shall not be sufficient to effect the conversion of all then outstanding shares of
Preferred Stock, the Corporation shall promptly seek such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such
purpose. In the event of the consolidation or merger of the Corporation with another corporation where the Corporation is not the surviving corporation, effective provisions shall be made in the certificate or articles of incorporation, merger or
consolidation, or otherwise of the surviving corporation so that such corporation will at all times reserve and keep available a sufficient number of shares of Common Stock or other securities or property to provide for the conversion of Preferred
Stock in accordance with the provisions of this Section 5. 
 (l)        Payment of
Taxes. The Corporation shall pay all taxes and other governmental charges (other than any income or other taxes imposed upon the profits realized by the recipient) that may be imposed in respect of the issue or delivery of shares of Common Stock
or other securities or property upon conversion of shares of Preferred Stock, excluding any tax or other charge imposed in connection with any transfer involved in the issue and delivery of shares of Common Stock or other securities in a name other
than that in which the shares of Preferred Stock so converted were registered. 

(m)        Status of Converted Stock. In the event any shares of Preferred Stock shall be
converted pursuant to Section 5 hereof, the shares so converted shall be canceled and 

  
 15 













 
shall not be issuable by the Corporation, and this Amended and Restated Certificate of Incorporation shall be appropriately amended to effect the corresponding reduction in the Corporation’s
authorized capital stock. 
 (n)        No Impairment. Subject to the right of this
Corporation to amend its Certificate of Incorporation or take any other corporate action upon obtaining the necessary approvals required by its Certificate of Incorporation and applicable law, the Corporation shall not amend this Amended and
Restated Certificate of Incorporation or participate in any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, for the purpose of avoiding or seeking to avoid the
observance or performance of any of the terms to be observed or performed hereunder by the Corporation, but shall at all times in good faith use its best efforts, and assist in carrying out all such action as may be reasonably necessary or
appropriate in order to protect the Conversion Rights of the holders of the Preferred Stock against dilution or other impairment.

Biosite’s expense, to have access during normal business hours to such of the records of Institution and the Licensees that Biosite has not had audited previously under this Agreement as may
be reasonably necessary to verify the accuracy of the payment reports hereunder for any year ending not more than twenty-four (24) months prior to the date of such request. If such accounting firm concludes that additional amounts were owed
during the audited period, Institution shall pay such additional amounts within thirty (30) days of the date Biosite delivers to Institution such accounting firm’s written report so concluding. The fees charged by such accounting firm
shall be paid by Biosite; provided, however, if the audit discloses that the royalties payable by Institution for such period are more than [***] of the royalties actually paid for such period, then Institution shall pay the reasonable fees and
expenses charged by such accounting firm. Biosite shall cause its accounting firm to retain all financial information subject to review under this Section 3.2 in strict confidence; provided, however, that Institution shall have the right to
require that such accounting firm, prior to conducting such audit, enter into an appropriate non-disclosure agreement with Institution regarding such financial information. The accounting firm shall disclose

designate before such payment is due.

4.1        Indemnity. Institution shall, and shall require its Licensees to,
indemnify and hold Biosite harmless, and hereby forever releases and discharges Biosite, from and against all losses, liabilities, damages and expenses (including reasonable attorneys’ fees and costs) resulting from all claims, demands, actions
and other proceedings by any Third Party to the extent arising from (a) the use of the Antibodies or the making, using or selling of Products by Institution, its Licensees or their Affiliates or sublicensees, (b) the use of any Target, or
the development, sale or delivery of an Antibody to the extent it is specific to any Target, by Biosite in performing the Services, or (c) the gross negligence or willful misconduct of Institution, its Licensees or their Affiliates or
sublicensees in the performance of its obligations, and its permitted activities, under this Agreement. Notwithstanding any other provision of this paragraph, Institution indemnifies Biosite hereunder, only in proportion to and to the extent that
all losses, liabilities, damages and expenses (including reasonable attorneys’ fees and costs) is caused by Institution, it directors, officers and 

  
 5 













 
employees. Additionally, Institution will require the same level of indemnification for Biosite in its commercial licenses, if any, arising from the Services hereunder as Institution obtains for
itself. 
 4.2        Procedure. Biosite shall promptly notify Institution of
any claim, demand, action or other proceeding for which Biosite intends to claim such indemnification. Institution shall have the right to participate in, and to the extent it so desires jointly with any other indemnitor similarly noticed, to assume
the defense thereof with counsel selected by Institution; provided, however, that Biosite shall have the right to retain its own counsel, with the fees and expenses to be paid by Institution, if representation of Biosite by the counsel retained by
Institution would be inappropriate due to actual or potential differing interests between Biosite and any other party represented by such counsel in such proceedings. Institution may not settle or otherwise consent to an adverse judgment in any such
claim, demand, action or other proceeding that diminishes the rights or interests of Biosite without the prior express written consent of Biosite, which consent shall not be unreasonably withheld or delayed. Biosite, its employees and agents, shall
reasonably cooperate with Institution and its legal representatives in the investigation of any claim, demand, action or other proceeding covered by this Section 4. 

4.3        Insurance. Institution or its Licensees hereunder shall maintain
such insurance with respect to the development, manufacture and sales of Products by Institution, its Affiliates or Licensees in such amounts as Institution, or its Licensees hereunder, customarily maintains with respect to the development,
manufacture and sales of its other products. Institution or its Licensees hereunder shall maintain such insurance for so long as it continues to develop, manufacture or sell Products, and thereafter for so long as it customarily maintains insurance
for itself covering the development, manufacture and sales of its other products. Biosite shall maintain liability insurance with financially sound and reputable insurers with insurance coverage against loss from such risks and in such amounts as is
customary for well-insured companies or institutions engaged in similar businesses or services, including comprehensive liability coverage with contractual liability coverage sufficient to cover its indemnification obligations under this Agreement.
