	 	(j)	Royalties in an amount equal to [***] of the MILESTONE PAYMENT received from a CORPORATE PARTNER as a result of achievement of an agreed upon regulatory or business milestone related to ADMINISTRATION SYSTEMS.

  

	 	(k)	In addition to Running Royalties, LICENSEE shall pay to M.I.T. [***] of lump sum type payments it receives from sublicensees (sublicense issue fees) for a grant to the bare PATENT RIGHTS, provided that such grant occurs
without a significant and approximately simultaneous grant to rights of LICENSEE owned technology, or without a significant and approximately simultaneous contractual obligation on the part of LICENSEE toward its sublicensee(s) to a) conduct
research related to commercialization of the PATENT RIGHTS or b) to provide its sublicensee(s) with LICENSED PRODUCTS for subsequent modification and sale, distribution, or transfer: 

4.2 All payments due hereunder shall be paid in full, without deduction of taxes or other fees which may be imposed by any government, except
as otherwise provided in Paragraph 1.5(b). 
 4.3 No multiple royalties shall be payable because any PARTICLE, its manufacture, use, lease
or sale are or shall be covered by more than one PATENT RIGHTS patent application or PATENT RIGHTS patent licensed under this Agreement.

4.6 It is understood that the same physical object, such as a PARTICLE, or THERAPEUTIC PARTICLE, may be sold multiple times. For example, a
PARTICLE could be sold to a sublicensee who makes a THERAPEUTIC PARTICLE out of it, then sells the THERAPEUTIC PARTICLE to another sublicensee, who incorporates it into an ADMINISTRATION SYSTEM, and sells that. M.I.T. and LICENSEE agree that
royalties will be payable each time an invoice is generated as a result of the sale of a LICENSED PRODUCT, even if the same physical object, albeit in altered form, is sold more than once. 

4.7 Royalty payments shall be paid in United States dollars in Cambridge, Massachusetts, or at such other place as M.I.T. may reasonably
designate consistent with the laws and regulations controlling in any foreign country. If any currency conversion shall be

confidential nature of the information using measures as strong as those it uses to protect its own confidential information. LICENSEE agrees that M.I.T. may share any information provided to M.I.T. under this article 5.2 with PSRF and also with
agents hired by M.I.T. under paragraph 5.1 pursuant to our right to audit LICENSEE’S royalty reports, provided that PSRF and any such agent shall have first agreed in writing to be bound by an obligation of confidentiality at least as
restrictive as that undertaken by M.I.T. under this section 5.2. 
 5.3 With each such report submitted, LICENSEE shall pay to M.I.T. the
royalties due and payable under this Agreement. If no royalties shall be due, LICENSEE shall so report. 
 5.4 On or before the ninetieth
(90th) day following the close of LICENSEE’S fiscal year, LICENSEE shall provide M.I.T. with LICENSEE’S certified financial statements for the preceding fiscal year including, at a minimum, a balance sheet and an income statement.

REQUEST. REDACTED MATERIAL IS MARKED WITH [* * *] AND HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION. 
  

 M.I.T. shall instruct Patrea Pabst, or another attorney mutually acceptable to M.I.T., PSRF,
and LICENSEE, to copy LICENSEE on all patent prosecution documents, and shall instruct Patrea Pabst or such other attorney not to proceed with a substantive action without receiving LICENSEE’S written approval, except, that not hearing from
LICENSEE within ten days after requesting LICENSEE’S approval shall be deemed to constitute such approval. 
 6.2 Payment of all fees
and costs relating to the filing, prosecution and maintenance of the PATENT RIGHTS shall be the responsibility of LICENSEE, whether such fees and costs were incurred before or after the EFFECTIVE DATE, provided however, LICENSEE shall not be
responsible for payment of any fees incurred following the termination of this Agreement. (As of June 26, 1997, such fees and costs for which M.I.T. has been billed equal approximately [***]. LICENSEE shall pay such fees and costs to M.I.T.
within thirty (30) days of invoicing; late payments shall accrue interest and shall be subject to Paragraph 5.5. 
 7. INFRINGEMENT

 7.1 LICENSEE shall inform M.I.T. promptly in writing of any alleged infringement of the PATENT RIGHTS by a third party and of any
available evidence thereof. 
 7.2 In the FIELD OF USE, LICENSEE shall have the right, but shall not be obligated, to prosecute at its own
expense all infringements of the PATENT RIGHTS and, in furtherance of such right, M.I.T. hereby agrees that LICENSEE may include M.I.T. as party plaintiff in any such suit, without expense to M.I.T. The total cost of any such infringement action
commenced or defended solely by LICENSEE shall be borne by LICENSEE, and LICENSEE shall keep any recovery or damages for past infringement derived therefrom. No settlement, consent judgment or other voluntary final disposition of the suit may be
entered into without the consent of M.I.T., which consent shall not unreasonably be withheld. LICENSEE shall indemnify M.I.T. against any order for costs that may be made against M.I.T. in such proceedings. 

7.3 If within six (6) months after having been notified of an alleged infringement, LICENSEE shall have been unsuccessful in persuading
the alleged infringer to desist and shall not have brought and shall not be diligently prosecuting an infringement action, or if LICENSEE shall notify M.I.T. at any time prior thereto of its intention not to bring suit against any alleged infringer
for the FIELD OF USE, then, and in those events only, M.I.T. shall have the right, but shall not be obligated, to prosecute at its own expense any infringement of the PATENT RIGHTS in the FIELD OF USE, and M.I.T. may, for such purposes, use the name
of LICENSEE as party plaintiff. The total cost of any such infringement action commenced or defended solely by M.I.T. shall be borne by M.I.T. and M.I.T. shall keep any recovery or damages for past infringement derived therefrom. 

7.4 In the event that LICENSEE shall undertake litigation for the enforcement of the PATENT RIGHTS, or the defense of the PATENT RIGHTS under
this Article 7, LICENSEE 

  
 -16-

REQUEST. REDACTED MATERIAL IS MARKED WITH [* * *] AND HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION. 
  

 
may withhold up to [***] of the payments otherwise thereafter due M.I.T. under Article 4 hereunder and apply the same toward reimbursement of up to half of LICENSEE’S expenses, including
reasonable attorneys’ fees, in connection therewith. Any recovery of damages by LICENSEE for each such suit shall be applied first in satisfaction of any unreimbursed expenses and legal fees of LICENSEE relating to such suit, and next toward
reimbursement of M.I.T. for any payments under Article 4 past due or withheld and applied pursuant to this Article 7. If any M.I.T. royalties have been withheld pursuant to this clause, the balance remaining from any such recovery due to M.I.T.
shall be calculated by creating a fraction, the numerator of which is the amount of royalties withheld, and the denominator of which is the cost of litigation paid by LICENSEE, and multiplying said fraction by the balance remaining, but in no event
shall such sum be less than Ten Percent (10%) of the balance remaining. 
 7.5 In the event that (a) LICENSEE undertakes the
enforcement and/or defense of the PATENT RIGHTS by litigation, and (b) LICENSEE demonstrates by competent proof that an infringer’s activity is substantially affecting LICENSEE’S sales, and that LICENSEE’S sales of LICENSED
PRODUCTS and LICENSED PROCESSES have declined by at least [***] during the period of infringement, then, for a period not to exceed two years, LICENSEE may withhold up to [***] of the payments otherwise due M.I.T. under Article 4 hereunder and apply
the same toward reimbursement of LICENSEE’S expenses, including reasonable attorney’s fees in connection therewith. Any recovery of damages by LICENSEE for each such suit shall be applied first in satisfaction of any unreimbursed expenses
and legal fees of LICENSEE relating to such suit, and next toward reimbursement of M.I.T. for payments under article 4 past due or withheld and applied pursuant to this Article 7. If any M.I.T. royalties have been withheld pursuant to this clause,
the balance remaining from any such recovery due to M.I.T. shall be calculated by creating a fraction, the numerator of which is the amount of royalties withheld, and the denominator of which is the cost of litigation paid by LICENSEE, and
multiplying said fraction by the balance remaining, but in no event shall such sum be less than [***] of the balance remaining. 
 7.6 In
the event that a declaratory judgment action alleging invalidity or noninfringement of any of the PATENT RIGHTS shall be brought against LICENSEE, LICENSEE shall within ten (10) days after the commencement of such action notify M.I.T. as to
whether or not LICENSEE intends to defend such action. In the event LICENSEE notifies M.I.T. that LICENSEE intends to defend such action, LICENSEE shall take over the sole defense of the action at its own expense. In the event LICENSEE notifies
M.I.T. that it intends not to defend such action, or that it intends to discontinue the defense of such action, M.I.T. at its sole option, shall have the right, within thirty (30) days of such notice, to intervene and take over the sole defense
of the action at its own expense, subject to Paragraph 7.4. 
 7.7 In any infringement suit as either party may institute to enforce the
PATENT RIGHTS pursuant to this Agreement, the other party hereto shall, at the request and expense of the party initiating such suit, cooperate in all respects and, to the extent possible, have its employees testify when requested and make available
relevant records, papers, information, samples, specimens, and the like.

 7.8 LICENSEE shall have the sole right in accordance with the terms and conditions herein to
sublicense any alleged infringer in the FIELD OF USE for future use of the PATENT RIGHTS. Any fees as part of such a sublicense shall be treated per Article 4. 

8. PRODUCT LIABILITY 
 8.1
LICENSEE shall at all times during the term of this Agreement and thereafter, indemnify, defend and hold M.I.T., its trustees, directors, officers, employees and affiliates, and PSRF and its trustees, directors, officers, employees and affiliates,

8.2 Before the first clinical use of a LICENSED PRODUCT or LICENSED PROCESSES, LICENSEE shall obtain and carry in full force and effect
commercial, general liability insurance, including product liability and errors and omissions insurance, which shall protect LICENSEE and M.I.T. and PSRF with respect to events covered by Paragraph 8.1 above. Such insurance shall be written by a
reputable insurance company authorized to do business in the Commonwealth of Massachusetts, shall list M.I.T. and PSRF as additional named insured parties thereunder, shall be endorsed to include product liability coverage and shall require thirty
(30) days written notice to be given to M.I.T. and PSRF prior to any cancellation or material change thereof. The limits of such insurance shall not be less than [***] per occurrence with an aggregate of [***] for personal injury including
death; [***] per occurrence with an aggregate of [***] for property damage; and [***] per occurrence with an aggregate of [***] for errors and omissions. LICENSEE shall provide M.I.T. and PSRF with Certificates of Insurance evidencing the same. 

8.3 EXCEPT AS OTHERWISE EXPRESSLY SET FORTH IN THIS AGREEMENT, M.I.T., ITS TRUSTEES, DIRECTORS, OFFICERS, EMPLOYEES, AND AFFILIATES, AND PSRF
AND ITS TRUSTEES, DIRECTORS, OFFICERS, EMPLOYEES, AND AFFILIATES, MAKE NO REPRESENTATIONS AND EXTEND NO WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE,
VALIDITY OF PATENT RIGHTS CLAIMS, ISSUED OR PENDING, AND THE ABSENCE OF LATENT OR OTHER DEFECTS, WHETHER OR NOT DISCOVERABLE. NOTHING IN THIS AGREEMENT SHALL BE CONSTRUED AS A REPRESENTATION MADE OR WARRANTY GIVEN BY M.I.T. OR PSRF THAT THE PRACTICE
BY LICENSEE OF THE LICENSE GRANTED HEREUNDER SHALL NOT INFRINGE THE PATENT RIGHTS OF ANY THIRD PARTY. 
 8.4 IN NO EVENT SHALL M.I.T., ITS
TRUSTEES, DIRECTORS, OFFICERS, EMPLOYEES AND AFFILIATES, OR PSRF, ITS TRUSTEES, DIRECTORS, OFFICERS, EMPLOYEES AND AFFILIATES, BE LIABLE FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY KIND, INCLUDING ECONOMIC DAMAGE OR INJURY TO

PROPERTY AND LOST PROFITS, REGARDLESS OF WHETHER M.I.T. OR PSRF SHALL BE ADVISED, SHALL HAVE OTHER REASON TO KNOW, OR IN FACT SHALL KNOW OF THE POSSIBILITY OF THE FOREGOING. 

9. EXPORT CONTROLS 

LICENSEE acknowledges that it is subject to United States laws and regulations controlling the export of technical data, computer software,
laboratory prototypes and other commodities (including the Arms Export Control Act, as amended and the United States Department of Commerce Export Administration Regulations). The transfer of such items may require a license from the cognizant
agency of the United States Government and/or written assurances by LICENSEE that LICENSEE shall not export data or commodities to certain foreign countries without prior approval of such agency. M.I.T. neither represents that a license shall not be
required nor that, if required, it shall be issued. 
 10. NON-USE OF NAMES 

LICENSEE shall not use the names or trademarks of the Massachusetts Institute of Technology or Lincoln Laboratory, or the Pennsylvania State
Research Foundation, nor any adaptation thereof, nor the names of any of their employees, in any advertising, promotional or sales literature without prior written consent obtained from M.I.T., or the Pennsylvania State Research Foundation, or said
employee, except that LICENSEE may state that it is licensed by M.I.T. and/or PSRF under one or more of the patents and/or applications comprising the PATENT RIGHTS and may identify the inventors of such patents and or applications. 

11. ASSIGNMENT 
 This
Agreement is not assignable and any attempt to do so shall be void; provided, however, LICENSEE may assign this Agreement in connection with the sale or transfer of all or substantially all of LICENSEE’S equity and assets related to LICENSED
PRODUCTS by merger, consolidation or otherwise, so long as the assignee shall agree in writing to be bound by all the terms and conditions hereof prior to such assignment. Failure of such assignee to so agree shall be grounds for termination by
M.I.T. under paragraph 13.3. 
 12. DISPUTE RESOLUTION 

12.1 Except for the right of either party to apply to a court of competent jurisdiction for a temporary restraining order, a preliminary
injunction, or other equitable relief to preserve the status quo or prevent irreparable harm, any and all claims, disputes or controversies arising under, out of, or in connection with the Agreement, including any dispute relating to patent validity
or infringement, which the parties shall be unable to resolve within sixty (60) days shall be mediated in good faith. The party raising such dispute shall promptly advise the other party of such claim, dispute or controversy in a writing which
describes in reasonable detail the nature of such dispute. By not later than five (5) business days after the recipient has received such notice of dispute, each party shall have selected for itself a representative who shall have the authority

not been able to resolve the dispute within fifteen (15) business days after such mediation hearing, then any and all claims, disputes or controversies arising under, out of, or in connection with this Agreement, including any dispute relating
to patent validity or infringement, shall be resolved by final and binding arbitration in Boston, Massachusetts under the rules of the American Arbitration Association, or the Patent Arbitration Rules if applicable, then obtaining. The arbitrators
shall have no power to add to, subtract from or modify any of the terms or conditions of this Agreement, nor to award punitive damages. Any award rendered in such arbitration may be enforced by either party in either the courts of the Commonwealth
of Massachusetts or in the United States District Court for the District of Massachusetts, to whose jurisdiction for such purposes M.I.T. and LICENSEE each hereby irrevocably consents and submits.

Agreement and shall submit the reports required by Article 5 hereof. 
 13.6 Upon termination of this Agreement for any reason, any
sublicensee not then in default shall have the right to seek a license from M.I.T. M.I.T. agrees to negotiate such licenses in good faith under reasonable terms and conditions.

Case No. [***] 
 M.I.T. Case No. [***] 

Because of the M.I.T. license granted to the above company and my equity1 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 2.12.2, “Relations of Faculty and Students,” in the Policies 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.
