(c) Running Royalties. COMPANY shall pay to M.I.T. a running royalty of [**] percent ([**]%) of NET SALES by COMPANY, AFFILIATES and
SUBLICENSEES 
 (d) Sharing of SUBLICENSE INCOME. COMPANY shall pay M.I.T. [**] percent ([**]%) of all SUBLICENSE INCOME received by
COMPANY or AFFILIATES. Such amount shall be payable for each REPORTING PERIOD in which SUBLICENSE INCOME is received and shall be due to M.I.T. within [**] days of the end of each REPORTING PERIOD. 

(e) No Multiple Royalties. If the manufacture, use, lease, or sale of any LICENSED PRODUCT or the performance of any LICENSED PROCESS
is covered by more than one of the PATENT RIGHTS, multiple royalties shall not be due. 
 (f) Equity. 

(i) Initial Grant. COMPANY shall issue a total of
                    (        ) shares of Common Stock of COMPANY, $0.0001 par value per share, (the
“Shares”) in the name of M.I.T. and of such persons as M.I.T. shall direct (“M.I.T. Holder”), and each M.I.T. Holder shall receive such number of shares as M.I.T. shall direct. Such issuance shall be recorded on the Stock
Transfer Ledger of COMPANY on the EFFECTIVE DATE and the Shares shall be delivered to M.I.T. and M.I.T. Holders, if any, within [**] days of the EFFECTIVE DATE. 

COMPANY represents to M.I.T. that, as of the Effective Date, the aggregate number of Shares equals Five Percent (5%) of the
COMPANY’S issued and outstanding Common Stock calculated on a “Fully Diluted Basis” following the issuance of the Shares. For purposes of this Section 4.1(g), “Fully Diluted Basis” shall mean that the total number of
issued and outstanding shares of the COMPANY’S Common Stock shall be calculated to include conversion of all issued and outstanding securities then convertible into common stock, the 

  
 10 








 
exercise of all then outstanding options and warrants to purchase shares of common stock, whether or not then exercisable, and shall assume the issuance or grant of all securities reserved for
issuance pursuant to any COMPANY stock or stock option plan in effect on the date of the calculation. 
 (ii) Anti-Dilution
Protection. COMPANY shall issue additional shares of Common Stock to M.I.T. and each M.I.T. Holder pro rata, such that M.I.T.’s and each M.I.T. Holders’ ownership of outstanding Common Stock shall not fall below Five Percent
(5%) on a Fully Diluted Basis, as calculated after giving effect to the anti-dilutive issuance. Such issuances shall continue until a total of [**] Dollars ($[**]) in cash in exchange for COMPANY’S capital stock (the “Funding
Threshold”) shall be received by COMPANY. Thereafter, no additional shares shall be due to M.I.T. or any M.I.T. Holder pursuant to this section. For the avoidance of doubt, if a single COMPANY financing causes COMPANY to reach and exceed more
than $[**] in cumulative funds raised, then the provisions of this Section shall apply with respect to that portion of such financing up to $[**] and not for that portion of such financing that exceeds such $[**] threshold. 

(iii) Participation in Future Private Equity Offerings. After the date of the Funding Threshold, M.I.T. (specifically not including
M.I.T. Holders) shall have the right to purchase additional shares of the COMPANY’S Common Stock in any private offering by the COMPANY of its equity securities in exchange for cash, to maintain its pro rata ownership as calculated immediately
prior to such offering on a Fully Diluted Basis, pursuant to the terms and conditions as those granted to the other offerees. All rights granted to M.I.T. pursuant to this Section 4.1(g)(iii) shall terminate immediately prior to a firm
commitment underwritten public offering of the COMPANY’S common stock resulting in gross proceeds to the COMPANY of at least $[**]. M.I.T.’s rights under this Section shall not apply to the following equity securities (i) shares of
Common Stock issued or issuable to employees, consultants or directors of COMPANY pursuant to an option plan (including shares issued or issuable upon exercise of options already granted); (ii) securities issued in connection with any stock
split or stock dividend by COMPANY; (iii) and shares of Common Stock issued upon conversion of COMPANY Preferred Stock; (iv) securities issued in consideration for the acquisition or licensing of technology or a corporate


  
 11 








 
partnership transaction or acquisition of another entity; or (v) securities issued in equipment leasing or other debt financing transactions. 

(iv) Adjustments for Punitive Round Financings. After the date of the Funding Threshold (the “Funding Threshold Date”) and
through the date at which COMPANY has raised a total of [**] Dollars ($[**]) in cash in exchange for COMPANY stock, if COMPANY issues Common Stock, or any equity security exercisable for or convertible into Common Stock, such that the price per
share of COMPANY’S Common Stock is. less than the M.I.T. Share Price (as defined below) (a “Dilutive Issuance”), then immediately following such Dilutive Issuance, COMPANY shall issue to M.I.T. shares of Common Stock such that the
M.I.T. Share Number (as defined below) equals the product obtained by multiplying the M.I.T. Share Number in effect immediately before the Dilutive Issuance by the Adjustment Fraction defined below. The M.I.T. Share Price in effect immediately after
the Dilutive Issuance shall be adjusted to equal the result obtained by dividing the M.I.T. Share Price in effect immediately before the Dilutive Issuance by the Adjustment Fraction defined below. 

 

							
	The Adjustment Fraction equals:	 	 	(A + C	) 	 	
		 	 	(A + B	) 	 	
	 where:
	 				 	

 A = the number of shares of Common Stock issued and outstanding on a Fully Diluted Basis immediately prior to
the Dilutive Issuance 
 B = the number of shares of Common Stock that could be purchased at the M.I.T. Share Price immediately prior to the
Dilutive Issuance using the net aggregate consideration received by COMPANY in connection with the Dilutive Issuance 
 C = the number of
shares of Common Stock or of a security exercisable for or convertible into Common Stock issued, on a Fully Diluted Basis, pursuant to the Dilutive Issuance. 

Notwithstanding the foregoing, M.I.T.’s rights under this Section shall not apply to the following equity securities (i) shares of Common Stock
issued or issuable to employees, consultants or directors of COMPANY pursuant to an option plan (including shares issued or issuable upon exercise of options already granted); (ii) securities issued in connection with any stock split or stock
dividend by COMPANY; (iii) and shares of Common Stock issued upon conversion of 

  
 12 








 
COMPANY Preferred Stock; (iv) securities issued in consideration for the acquisition or licensing of technology or a corporate partnership transaction or acquisition of another entity; or
(v) securities issued in equipment leasing or other debt financing transactions. 
 In addition, the following definitions shall apply to this
Section 4.1(f)(iv): 
 “Fair Market Value” of a share of Common Stock shall be the highest price per share that the COMPANY
could obtain from a willing buyer (not a current employee or director) for shares of Common Stock sold by the COMPANY, from authorized but unissued shares, as determined in good faith by the Board of Directors of the COMPANY, unless the COMPANY
shall become subject to a merger, acquisition or other consolidation pursuant to which the COMPANY is not the surviving party, in which case the current fair market value of a share of Common Stock shall be deemed to be the value received by the
holders of the COMPANY’S Common Stock for each share of Common Stock pursuant to the COMPANY’S acquisition. 
 “M.I.T. Share
Number” shall mean the number of shares of COMPANY’S Common Stock that M.I.T. owns on the date of the Dilutive Issuance, as adjusted from time to time pursuant to this section. Notwithstanding the foregoing, any shares of Common Stock
acquired by M.I.T. pursuant to Section 4.1(g)(iii) shall not be included in the M.I.T. Share Number. 
 “M.I.T. Share Price”
shall mean the value per share of the shares of Common Stock included in the M.I.T. Share Number, as adjusted from time to time pursuant to this section. For purposes of this section, the initial M.I.T. Share Price to be used in an adjustment
resulting from the first Dilutive Issuance to occur after the Funding Threshold Date shall be the Fair Market Value per share of the Common Stock of the COMPANY effective on the Funding Threshold Date. 

4.2. Payments. 
 (a)
Method of Payment. All payments under this Agreement should be made payable to “Massachusetts Institute of Technology” and sent to the address identified in Section 14.1. Each payment should reference this Agreement and
identify the obligation under this Agreement that the payment satisfies.

 (b) Payments in U.S. Dollars. All payments due under this Agreement shall be drawn on a
United States bank and shall be payable in United States dollars. Conversion of foreign currency to U.S. dollars shall be made at the conversion rate existing in the United States (as reported in the Wall Street Journal) on the last working
day of the calendar quarter of the applicable REPORTING PERIOD. Such payments shall be without deduction of exchange, collection, or other charges, and, specifically, without deduction of withholding or similar taxes or other government imposed fees
or taxes, except as permitted in the definition of NET SALES. 
 (c) Late Payments. Any payments by COMPANY that are not paid on or
before the date such payments are due under this Agreement shall bear interest, to the extent permitted by law, at [**] over the Prime Rate of interest as reported in the Wall Street Journal on the date payment is due.

5.1. Frequency of Reports. 

(a) Before First Commercial Sale. Prior to the first commercial sale of any LICENSED PRODUCT or first commercial performance of any

any reports delivered to M.I.T. and compliance in other respects with this Agreement. The relevant party shall retain such records for at least [**] years following the end of the calendar year to which they pertain, during which time M.I.T., or
M.I.T.’s appointed agents, shall have the right, at M.I.T.’s expense, to inspect such records during normal business hours not more than [**] period to verify any reports and payments made or compliance in other respects under this

reasonable opportunities to advise M.I.T. and shall cooperate with M.I.T. in such filing, prosecution and maintenance. COMPANY shall have reasonable opportunities to advise M.I.T. and shall cooperate with M.I.T. in such preparation, filing,
prosecution and maintenance. M.I.T. will instruct its patent attorney to copy COMPANY on all patent prosecution documents relating to PATENT RIGHTS during the TERM. 

6.2. International (non-United States) Filings. Appendix B is a list of countries in which patent applications corresponding to
the United States patent applications listed in Appendix A shall be filed, prosecuted, and maintained. Appendix B may be amended by mutual agreement of COMPANY and MIT. MIT shall not unreasonably withhold its consent to amendment of
Appendix B requested by COMPANY. 
 6.3. Abandoning Patent Rights. Should M.I.T. elect to abandon any PATENT RIGHTS, M.I.T. will
first notify COMPANY of its intent to do so sufficiently in advance for COMPANY to continue prosecution and maintain of such PATENT RIGHTS, and COMPANY may prosecute and maintain such PATENT RIGHTS in M.I.T.’s name at COMPANY’S own
expense. 
 6.4. Payment of Expenses. Payment of all fees and costs, including attorneys’ fees, relating to the filing,
prosecution and maintenance of the PATENT RIGHTS shall be the responsibility of COMPANY, whether such amounts were incurred before or after the EFFECTIVE DATE. As of [**], M.I.T. has incurred approximately $[**] for such patent-related fees and
costs. COMPANY shall reimburse all amounts due pursuant to this Section within [**] days of invoicing; late payments shall accrue interest pursuant to Section 4.2(c). In all instances, M.I.T. shall pay the fees prescribed for large entities to
the United States Patent and Trademark Office. 
 7. INFRINGEMENT. 

7.1. Notification of Infringement. Each party agrees to provide written notice to the other party promptly after becoming aware of any
infringement of the PATENT RIGHTS. 

  
 17 








 7.2. Right to Prosecute Infringements. 

(a) COMPANY Right to Prosecute. So long as COMPANY remains the exclusive licensee of the PATENT RIGHTS in the FIELD in the TERRITORY,
COMPANY, to the extent permitted by law, shall have the right, under its own control and at its own expense, to prosecute any third party infringement of the PATENT RIGHTS in the FIELD in the TERRITORY, subject to Sections 7.4 and 7.5. If required
by law, M.I.T. shall permit any action under this Section to be brought in its name, including being joined as a party-plaintiff, provided that COMPANY shall hold M.I.T. harmless from, and indemnify M.I.T. against, any costs, expenses, or liability
that M.I.T. incurs in connection with such action. 
 Prior to commencing any such action, COMPANY shall consult with M.I.T. and shall
consider the views of M.I.T. regarding the advisability of the proposed action and its effect on the public interest. COMPANY shall not enter into any settlement, consent judgment, or other voluntary final disposition of any infringement action
under this Section without the prior written consent of M.I.T., not to be unreasonably withheld. 
 (b) M.I.T. Right to Prosecute. In
the event that COMPANY is unsuccessful in persuading the alleged infringer to desist or fails to have initiated an infringement action within [**] days after COMPANY first becomes aware of the basis for such action, M.I.T. shall have the right, at
its sole discretion, to prosecute such infringement under its sole control and at its sole expense, and any recovery obtained shall belong to M.I.T. If required by law, COMPANY hereby agrees that M.I.T. may include COMPANY as a party-plaintiff in
any such suit, without expense to COMPANY. Prior to commencing any such action, M.I.T. shall consult with COMPANY and shall consider the views of COMPANY regarding the advisability of the proposed action. Further, M.I.T. shall not enter into any
settlement, consent judgment, or other voluntary final disposition of any infringement action under this Section without first consulting with and considering the views of COMPANY. Notwithstanding the forgoing, any action taken under this Section
shall be at the sole discretion of M.I.T. 
 7.3. Declaratory Judgment Actions. In the event that a declaratory judgment action is
brought against M.I.T. or COMPANY by a third party alleging invalidity, unenforceability, or non-infringement of the PATENT RIGHTS, COMPANY, at its option, shall have the right within 

  
 18 








 
[**] days after commencement of such action to take over the sole defense of the action at its own expense. If COMPANY does not exercise this right, M.I.T. may take over the sole defense of the
action at M.I.T.’s sole expense, subject to Sections 7.4 and 7.5. 
 7.4. Offsets. COMPANY may offset a total of [**] percent
([**]%) of any expenses incurred under Sections 7.2 and 7.3 against any payments due to M.I.T. under Sections 4.1(b) and 4.1(d); provided that, in no event shall such payments under Sections 4.1 (b) and 4.1 (d) be reduced by more than [**]
percent ([**]%) in any REPORTING PERIOD, it being understood that any expenses which COMPANY is prevented by the foregoing provision from offsetting in any REPORTING PERIOD may be carried forward and offset in one or more subsequent REPORTING
PERIODS (applying the foregoing proviso in each subsequent REPORTING PERIOD). 
 7.5. Recovery. Any recovery obtained in an action
brought by COMPANY under Sections 7.2 or 7.3 shall be distributed as follows: (i) each party shall be reimbursed for any expenses incurred in the action, (ii) all remaining recoveries received in any such action shall be retained by
COMPANY and deemed lost profits by COMPANY, as a result of which M.I.T. shall be entitled to receive royalties equal to the royalty rate set forth in Section 4.1(c) applied to such remaining recovery multiplied by [**]. 

7.6. Cooperation. Each party agrees to cooperate in any action under this Article which is controlled by the other party, provided that
the controlling party reimburses the cooperating party promptly for any costs and expenses incurred by the cooperating party in connection with providing such assistance. 

8. INDEMNIFICATION AND INSURANCE 

8.1. Indemnification. 

(a) Indemnity. COMPANY shall indemnify, defend, and hold harmless M.I.T. and its trustees, officers, faculty, students, employees, and
agents and their respective successors, heirs and assigns (the “Indemnitees”), against any liability, damage, loss, or expense (including reasonable attorney’s fees and expenses) (collectively, “Losses”) incurred by or
imposed upon any of the Indemnitees in connection with any claims, suits, actions, demands or judgments arising out 

  
 19 








 
of any theory of liability (including without limitation actions in the form of tort, warranty, or strict liability and regardless of whether such action has any factual basis) concerning any
product, process, or service that is made, used, sold, imported, or performed pursuant to any right or license granted under this Agreement; provided, however that COMPANY shall have no obligation pursuant to the foregoing with respect to any Losses
that result from the gross negligence or willful misconduct of any Indemnitee. 
 (b) Procedures. The Indemnitees agree to provide
COMPANY with prompt written notice of any claim, suit, action, demand, or judgment for which indemnification is sought under this Agreement. COMPANY agrees, at its own expense, to provide attorneys reasonably acceptable to M.I.T. to defend against
any such claim. The Indemnitees shall cooperate fully with COMPANY in such defense and will permit COMPANY to conduct and control such defense and the disposition of such claim, suit, or action (including all decisions relative to litigation,
appeal, and settlement); provided, however, that any Indemnitee shall have the right to retain its own counsel, at the expense of COMPANY, if representation of such Indemnitee by the counsel retained by COMPANY would be inappropriate because of
actual or potential differences in the interests of such Indemnitee and any other party represented by such counsel. COMPANY agrees to keep M.I.T. informed of the progress in the defense and disposition of such claim and to consult with M.I.T. with
regard to any proposed settlement. 
 8.2. Insurance. Before the first human use of a LICENSED PRODUCT or LICENSED PROCESS, COMPANY
shall obtain and carry in full force and effect commercial general liability insurance, including product liability insurance which shall protect COMPANY and Indemnitees with respect to events covered by Section 8.1(a) above. Such insurance
(i) shall be issued by an insurer licensed to practice in the Commonwealth of Massachusetts or an insurer pre-approved by M.I.T., such approval not to be unreasonably withheld, (ii) shall list M.I.T. as an additional insured thereunder,
(iii) shall be endorsed to include product liability coverage, and (iv) shall require [**] days written notice to be given to M.I.T. prior to any cancellation or material change thereof. The limits of such insurance shall not be less than
[**] Dollars ($[**]) per occurrence with an aggregate of [**] Dollars ($[**]) for bodily injury including death; and [**] Dollars ($[**]) per occurrence with an aggregate of [**] Dollars ($[**]) for property damage. In the alternative, COMPANY may
self-insure subject to prior approval of M.I.T. COMPANY shall provide M.I.T. 

  
 20 








 
with Certificates of Insurance evidencing compliance with this Section. COMPANY shall continue to maintain such insurance or self-insurance after the expiration or termination of this Agreement
during any period in which COMPANY or any AFFILIATE or SUBLICENSEE continues (i) to make, use, or sell a product that was a LICENSED PRODUCT under this Agreement or (ii) to perform a service that was a LICENSED PROCESS under this
Agreement, and thereafter for a period of [**] years. 
 9. NO REPRESENTATIONS OR WARRANTIES 

M.I.T. hereby represents and warrants to COMPANY that, to the best of its knowledge, M.I.T. is the owner of the entire right, title and
interest in the PATENT RIGHTS and in the inventions described and claimed therein and has the right to grant the licenses granted herein. M.I.T. has not granted to any third party any right or interest in the PATENT RIGHTS inconsistent or in
conflict with the rights granted to COMPANY hereunder. MIT’s entire liability under this representation and warranty is limited to the amounts paid to MIT under this Agreement. 

EXCEPT AS MAY OTHERWISE BE EXPRESSLY SET FORTH IN THIS AGREEMENT, M.I.T. MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND CONCERNING THE
PATENT RIGHTS, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, VALIDITY OF PATENT RIGHTS CLAIMS, WHETHER ISSUED OR PENDING, AND THE ABSENCE OF LATENT OR OTHER
DEFECTS, WHETHER OR NOT DISCOVERABLE. Specifically, and not to limit the foregoing, M.I.T. makes no warranty or representation (i) regarding the validity or scope of the PATENT RIGHTS, and (ii) that the exploitation of the PATENT RIGHTS or
any LICENSED PRODUCT or LICENSED PROCESS will not infringe any patents or other intellectual property rights of M.I.T. or of a third party. 

IN NO EVENT SHALL M.I.T, ITS TRUSTEES, DIRECTORS, OFFICERS, EMPLOYEES AND AFFILIATES BE LIABLE FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY
KIND, INCLUDING ECONOMIC DAMAGES OR INJURY TO PROPERTY AND LOST PROFITS, REGARDLESS OF WHETHER M.I.T. SHALL BE 

  
 21 








 
ADVISED, SHALL HAVE OTHER REASON TO KNOW, OR IN FACT SHALL KNOW OF THE POSSIBILITY OF THE FOREGOING. 

10. ASSIGNMENT. 
 This
Agreement is personal to COMPANY and no rights or obligations may be assigned by COMPANY without the prior written consent of M.I.T, except that COMPANY may assign its rights and obligations under this Agreement without the consent of M.I.T. in
connection with any sale of all or substantially all of the shares or assets of COMPANY or the assets of COMPANY to which this Agreement relates or in connection with any merger, consolidation, reorganization or similar business combination or
change of control of COMPANY.

the export of certain commodities and technical data, including without limitation all Export Administration Regulations of the United States Department of Commerce. Among other things, these laws and regulations prohibit or require a license for
the export of certain types of commodities and technical data to specified countries. COMPANY hereby gives written assurance that it will comply with, and will cause its AFFILIATES and SUBLICENSEES to comply with, all United States export control
laws and regulations, that it bears sole responsibility for any violation of such laws and regulations by itself or its AFFILIATES or SUBLICENSEES, and that it will indemnify, defend, and hold M.I.T. harmless (in accordance with Section 8.1)
for the consequences of any such violation. 
 11.3. Non-Use of M.I.T. Name. COMPANY and its AFFILIATES and SUBLICENSEES shall not
use the name of “Massachusetts Institute of Technology” or any variation, adaptation, or abbreviation thereof, or of any of its trustees, officers, faculty, students, employees, or agents, or any trademark owned by M.I.T, or any terms of
this Agreement in any 

  
 22 








 
promotional material or other public announcement or disclosure without the prior written consent of M.I.T. The foregoing notwithstanding, without the consent of M.I.T, COMPANY may state that it
is licensed by M.I.T. under one or more of the patents and/or patent applications comprising the PATENT RIGHTS.

Agreement with the number of each issued patent under the PATENT RIGHTS that applies to such LICENSED PRODUCT. 
 12. TERMINATION 

12.1. Voluntary Termination by COMPANY. COMPANY shall have the right to terminate this Agreement, for any reason, (i) upon at
least six (6) months prior written notice to M.I.T, such notice to state the date at least six (6) months in the future upon which termination is to be effective, and (ii) upon payment of all amounts due to M.I.T. through such

Section 3.1 occurring after the Termination Threshold has been met (as defined in such Section) or a breach as described in 

  
 23 








 
Section 12.3(a), and fails to cure that breach within [**] days after receiving written notice thereof, M.I.T. may terminate this Agreement immediately upon written notice to COMPANY. 

12.4. Effect of Termination. 

(a) Survival. The following provisions shall survive the expiration or termination of this Agreement: Articles 1, 8, 9, 13 and 14, and
Sections 4.1(g), 5.2 (obligation to provide final report and payment), 5.4, 11.1, 11.2 and 12.4. 
 (b) Inventory. Upon the early
termination of this Agreement, COMPANY and its AFFILIATES and SUBLICENSEES may complete and sell any work-in-progress and inventory of LICENSED PRODUCTS that exist as of the effective date of termination, provided that (i) COMPANY pays M.I.T.
the applicable running royalty or other amounts due on such sales of LICENSED PRODUCTS in accordance with the terms and conditions of this Agreement, and (ii) COMPANY and its AFFILIATES and SUBLICENSEES shall complete and sell all
work-in-progress and inventory of LICENSED PRODUCTS within [**] months after the effective date of termination.

provided that, M.I.T. shall not, in connection with such assumption, be required to assume any obligations that are greater than those contained in this Agreement and each such sublicense agrees in writing to continue to be bound by the terms of the
applicable sublicense as assumed by M.I.T. 
 (d) Pre-termination Obligations. In no event shall termination of this Agreement
release COMPANY, AFFILIATES, or SUBLICENSEES from the obligation to pay any amounts that became due on or before the effective date of termination. 

13. DISPUTE RESOLUTION. 

13.1. Mandatory Procedures. The parties agree that any dispute arising out of or relating to this Agreement shall be resolved solely by
means of the procedures set forth in this Article, and that such procedures constitute legally binding obligations that are an essential provision of this 

  
 24 








 
Agreement. If either party fails to observe the procedures of this Article, as may be modified by their written agreement, the other party may bring an action for specific performance of these
procedures in any court of competent jurisdiction. 
 13.2. Equitable Remedies. Although the procedures specified in this Article are
the sole and exclusive procedures for the resolution of disputes arising out of or relating to this Agreement, either party may seek a preliminary injunction or other provisional equitable relief if, in its reasonable judgment, such action is
necessary to avoid irreparable harm to itself or to preserve its rights under this Agreement. 
 13.3. Dispute Resolution Procedures.

 (a) Mediation. In the event any dispute arising out of or relating to this Agreement remains unresolved within [**] days from the
date the affected party informed the other party of such dispute, either party may initiate mediation upon written notice to the other party (“Notice Date”), whereupon both parties shall be obligated to engage in a mediation proceeding
under the then current Center for Public Resources (“CPR”) Model Procedure for Mediation of Business Disputes (http://www.cpradr.org), except that specific provisions of this Article shall override inconsistent provisions of the CPR Model
Procedure. The mediator will be selected from the CPR Panels of Neutrals. If the parties cannot agree upon the selection of a mediator within [**] business days after the Notice Date, then upon the request of either party, the CPR shall appoint the
mediator. The parties shall attempt to resolve the dispute through mediation until the first of the following occurs: (i) the parties reach a written settlement; (ii) the mediator notifies the parties in writing that they have reached an
impasse; (iii) the parties agree in writing that they have reached an impasse; or (iv) the parties have not reached a settlement within [**] days after the Notice Date. 

(b) Trial Without Jury. If the parties fail to resolve the dispute through mediation, or if neither party elects to initiate mediation,
each party shall have the right to pursue any other remedies legally available to resolve the dispute, provided, however, that the parties expressly waive any right to a jury trial in any legal proceeding under this Article. 

  
 25 








 13.4. Performance to Continue. Each party shall continue to perform its undisputed
obligations under this Agreement pending final resolution of any dispute arising out of or relating to this Agreement; provided, however, that a party may suspend performance of its undisputed obligations during any period in which the other party
fails or refuses to perform its undisputed obligations. Nothing in this Article is intended to relieve COMPANY from its obligation to make undisputed payments pursuant to Articles 4 and 6 of this Agreement. 

13.5. Statute of Limitations. The parties agree that all applicable statutes of limitation and time-based defenses (such as estoppel
and laches) shall be tolled while the procedures set forth in Sections 13.3(a) are pending. The parties shall cooperate in taking any actions necessary to achieve this result. 

14. MISCELLANEOUS. 
 14.1.

 Licensed Technology: M.I.T. Case No. [**]; M.I.T; Case No. [**] 

Because of the M.I.T. license granted to the above company and my equity* position and continuing relationship with this company, I acknowledge the potential
for a possible conflict of interest between the performance of research at M.I.T. and my contractual or other obligations to this company. Therefore, I will not 
  

	 	1)	use students at M.I.T, for research and development projects for the company; 

  

	 	2)	restrict or delay access to information from my M.I.T research; 

  

	 	3)	take direct or indirect research support from the company in order to support my activities at M.I.T; or 

  

	 	4)	employ students at the company, except in accordance with Section 4.5.2, “Faculty and Students,” in the Polictes and Procedures Guide. 


In addition, in order to avoid the appearance of a conflict, I will attempt to differentiate clearly between the intellectual directions of my M.I.T. research
and my contributions to the company. To that end, I will expressly inform my department head/laboratory director annually of the general nature of my activities on behalf of the company

 THIRD AMENDMENT 

This Amendment, with the effective date of July 30, 2009, is to the Exclusive Patent License Agreement dated December 21, 2006 (“License
Agreement”) between Massachusetts Institute of Technology (“MIT”) and Cerulean Pharma Inc. (formerly known as Tempo Pharmaceuticals, Inc., “COMPANY”). Capitalized terms used herein and not otherwise defined shall have the
meanings given such terms in the License Agreement. 
 BACKGROUND: 

MIT granted COMPANY an exclusive license to the Patent Rights in the License Agreement, with COMPANY agreeing that it would diligently seek to develop products
based on the technology of the Patent Rights. 
 COMPANY has devoted substantial resources in an attempt to develop “two drug” nanotechnology
therapeutic products based on the technology of the Patent Rights; however technical difficulties of manufacture and quality control under the current state of the art make continued attempts at development impractical at this time. 

COMPANY has meanwhile developed and acquired additional technologies and wishes to devote the majority of its efforts to development and marketing of
nanotechnology therapeutic products involving these additional technologies. 
 COMPANY and MIT believe that new technology for manufacture and quality
control of nanotechnology products developed in the course of pursuing these alternative nanotechnology therapeutic products may make development and manufacture of “two drug” nanotechnology therapeutic products based on the technology of
the Patent Rights practical in the future. 
 Therefore, COMPANY and MIT believe it appropriate for COMPANY to suspend, for a limited period of time, its
efforts to develop a “two drug” nanotechnology therapeutic product based on the technology of the Patent Rights, and the parties therefore agree to amend the License Agreement as follows: 

Amendments: 
  

	 	1.	COMPANY and MIT agree that as no patent applications were ever filed for M.I.T. case No. [**], the amendments to the License Agreement effected by the First Amendment dated July 30, 2007 (the “First
Amendment”) shall be of no force and effect and the language of the License Agreement shall revert to the language in existence prior to the date of the First Amendment, as later amended by the Second Amendment dated June 1, 2008 and as
now amended by this Third Amendment. 

  

	 	2.	The diligence terms of Sections 3(b), 3(c), 3(f), 3(g), 3(h), 3(i) and 3(j) shall be deleted in their entirety, but with the understanding that new diligence terms shall be agreed upon by the parties in accordance with
Section 4 below by June 30, 2014. 

  

	 	3.	Subject to Section 5 below, the license maintenance fee schedule under Section 4.1(b) of the License Agreement shall be revised as follows: 









					
	 January 1, 2010 and each January 1 thereafter through and including January 1, 2014
	  	$	[	**] 

  

	 	4.	By March 1, 2014, COMPANY shall present to MIT a plan for development of Licensed Products under the PATENT RIGHTS which is satisfactory to MIT and a proposal for new diligence terms for development of Licensed
Products. Thereupon, COMPANY and MIT shall negotiate in good faith the new diligence terms, which terms, once agreed upon, shall be added by further amendment to the License Agreement. In the event that COMPANY and MIT are unable to agree on new
diligence terms by June 30, 2014, MIT may, at its sole discretion, terminate the License Agreement immediately upon written notice to COMPANY. 

  

	 	5.	Beginning January 1, 2015, the following license maintenance fees shall apply: 

  

					
	 January 1, 2015
	  	$	[	**] 
	 January 1, 2016
	  	$	[	**] 
	 January 1, 2017
	  	$	[	**] 
	 January 1, 2018
	  	$	[	**] 
	 January 1, 2019
	  	$	[	**] 
	 January 1, 2020 and each January 1 thereafter
	  	$	[	**] 

  

	 	    	In the event that COMPANY and MIT agree on a new development plan for Licensed Products in a calendar year prior to 2014, the foregoing schedule of license maintenance fees shall be accelerated such that the first $[**]
shall be due on January 1 of the calendar year immediately subsequent to the calendar year in which agreement on the new development plan occurs. 

  

	 	6.	If at any time prior to June 30, 2014, if MIT becomes aware of a third party wishing to have a license to the Patent Rights to develop Licensed Products; and provided that (a) COMPANY has not provided MIT with
a satisfactory plan for development of the Patent Rights according to Section 4 above; and (b) COMPANY is not in active negotiations with the third party at the time that MIT becomes aware of the third party’s wishes for a license;
then: 

  

	 	    	(i) MIT shall request from both COMPANY and the third party, development plans to bring one or more Licensed Products to market; 


	 	    	(ii) MIT shall evaluate the development plans based on capability and commitment of each party to develop Licensed Products and bring them to market, and shall choose the plan it considers to be in the best interests of
the commercialization of the Patent Rights, at its sole discretion; and 


	 	    	(iii) If the third party’s plan is considered superior to that of COMPANY, MIT may, at its sole discretion, either terminate the License Agreement or limit the Field of Use or exclusivity of the License Agreement.


  

	 	7.	Appendix B to the License Agreement is hereby deleted in its entirety and the attached Appendix B is hereby substituted therefore. 









	 	8.	Except as specifically modified or amended hereby, all other terms and conditions of the License Agreement shall remain unchanged and in full force and effect. 


IN WITNESS WHEREOF, the parties have caused this Third Amendment to be executed under seal by their duly authorized representatives.

shall negotiate in good faith the new diligence terms, which terms, once agreed upon, shall be added by further amendment to the License Agreement. In the event that COMPANY and MIT are unable to agree on new diligence terms by June 30, 2015,
MIT may, at its sole discretion, terminate the License Agreement immediately upon written notice to COMPANY. 
  

	 	3.	Section 5 of the Third Amendment shall be replaced in its entirety as follows:
