(b) Additional Targets. Commencing upon a Potential Target becoming an Additional Target in accordance with Section 2.2(a) (Grant of Option), Selecta hereby grants to Spark an exclusive (even as to Selecta and its Affiliates) right and license in the Field in the Territory, with the right to grant sublicenses, under the Selecta IP (i) to use, offer for sale, sell, import and otherwise Develop and Commercialize Licensed Products directed to such Additional Target, (ii) to make, have made and otherwise Manufacture Licensed Products directed to such Additional Target excluding the making, having made or Manufacturing of any Licensed Particles within such Licensed Products and (iii) contingent upon exercise of the Technology Transfer Option, make, have made and otherwise Manufacture Licensed Particles solely for inclusion in Licensed Products directed to such Additional Target and solely in accordance with Section 5.3 (Manufacturing Transfer).

(c) Research License. Subject to the terms and conditions of this Agreement, Selecta hereby grants Spark a royalty-free, exclusive (even as to Selecta and its Affiliates) right and license, without any right to grant sublicenses, under the Selecta IP to perform research activities with respect to Potential Targets during the Option Period. Ownership of Inventions and Patents arising in the course of such activities shall be as set forth in Section 7.1(b) (Improvements). [***].

(a) Post-Royalty Term Licenses. Each license granted under Sections 2.1(a) (Initial Target) and 2.1(b) (Additional Targets) shall automatically convert to a fully paid-up, non-royalty bearing, perpetual, non-exclusive license on a country-by-country and Licensed Product-by-Licensed Product basis upon the expiration of the Royalty Term applicable to such Licensed Product in such country (but not upon an earlier termination of this Agreement with respect thereto).

(b) Third Party Licenses. The licenses set forth in Sections 2.1(a) (Initial Target), 2.1(b) (Additional Targets) and 2.1(c) (Research License) include sublicenses under the In-License Agreements. Selecta has, prior to the Effective Date, provided Spark with copies of the MIT License and the BIND Cross License. Spark acknowledges that its rights with respect to the In-Licensed Patents are subject to the terms and conditions of the applicable In-License Agreement, including the field limitations and rights reserved to Third Parties set forth therein. Spark shall comply with, and shall require its sublicensees to comply with, the following terms and conditions of the In-License Agreements applicable to Spark and its sublicensees thereunder: Sections 2.6 (Sublicenses), 2.7 (U.S. Manufacturing), 2.8 (Retained Rights), 5.4 (Records), 11.2 (Export Control), 11.3 (Non-Use of M.I.T., Xxxxxxx, Harvard, Institute and CMCC Names) and 11.4 (Marking of Licensed Products) of the MIT License and Sections 2.3 (Sublicense Rights), 3.2 (Patent Marking) and 3.4 (No Challenge) of the BIND Cross License. In the event that a sublicensee of Spark fails to comply with such terms and conditions, then at either Party’s request the Parties shall discuss alternatives for correcting such noncompliance, which under appropriate circumstances may include Spark’s termination of such sublicense, or, if necessary in order for Selecta to avoid termination of an In-License Agreement (i.e., no cure or other alternative that avoids such termination is possible), Selecta may terminate this Agreement with respect to the sublicenses granted under such In-License Agreement in this Agreement on thirty (30) days’ notice if such noncompliance remains uncured. In addition, Spark shall prepare and deliver to Selecta any additional reports required under the MIT License sufficiently in advance to enable Selecta to comply with its obligations thereunder and to enable Selecta to calculate “Net Sales” as defined in the MIT License. Spark acknowledges that the license grant to Selecta under (i) the MIT License with respect to MIT Case No. 7856 and (ii) the BIND Cross License with respect to the BIND Patents is non-exclusive, and, therefore, that the license grants to Spark under Sections 2.1(a) (Initial Target) and 2.1(b) (Additional Targets) with respect to such Patents shall be exclusive only as to Selecta’s rights under such Patents.

(c) Sublicenses. Spark shall have the right to grant sublicenses, through multiple tiers of sublicensees, under the licenses granted in Section 2.1(a) (Initial Target), Section 2.1(b) (Additional Targets) or Section 2.1(g) (Corporate Names), to its Affiliates and other Persons; provided that any such sublicenses shall (a) be consistent with the applicable terms and conditions of this Agreement and the MIT/Selecta/Spark Letter Agreement, and (b) include (i) record-keeping and audit provisions consistent with Section 6.16 (Maintenance of Records) and Section 6.17 (Audits), (ii) confidentiality obligations at least as restrictive as those set forth in ARTICLE 8 (Confidentiality), (iii) indemnification and insurance obligations consistent with those set forth in ARTICLE 11 (Indemnification, Insurance and Liability) and (iv) an assignment to Selecta of such sublicensee’s rights in Selecta-Assigned

Improvement IP and certain Spark Field-Specific Improvement IP pursuant to Section 7.1(b) (Improvements). Any such sublicensee must comply with the applicable terms and conditions of this Agreement, but Spark shall remain primary obligor under this Agreement and shall be responsible for the acts and omissions of any such sublicensee as if they were performed by Spark. Any such sublicense shall not alter in any manner the responsibility of the Spark hereunder, including its obligation to Selecta for the payment of all payments due under this Agreement. Promptly upon entry into any such sublicense, Spark shall provide Selecta a copy of such sublicense, [***]. Spark shall ensure that any sublicense of the In-Licensed Patents by Spark in accordance with this Section 2.1(f) is consistent with the terms and conditions of the applicable In-License Agreement.

(d) Corporate Names. Subject to the terms and conditions of this Agreement, commencing on the Effective Date, Selecta hereby grants to Spark a non-exclusive license, with the right to grant sublicenses in accordance with Section 2.1(f) (Sublicenses), to use Selecta’s Corporate Names solely as required to comply with Section 4.4 (Markings).

Period. Upon such expiration, all targets remaining on the Potential Target List shall cease to be Potential Targets under this Agreement.

(e) Indications. Within [***] after the Effective Date the Parties shall mutually determine the prevalence of the indications related to the Potential Targets. The designation of each Potential Target as related to a Rare Indication, a Very Rare Indication or neither a Rare Indication nor a Very Rare Indication shall be set forth on the Potential Target List and such designation shall be binding upon both Parties for all purposes hereunder. If the Parties fail to agree on such designation(s) initially, or if at a future date a Party believes that a designation should change and the other Party does not agree with such change, the Parties shall refer the matter to a mutually-agreeable technical expert to make such determination. In the event that the designation with respect to an Additional Target changes after relevant payments with respect to such Additional Target have been made, such change shall only affect payments that first become payable after the Parties first initiate discussions regarding the change in designation for such Additional Target.


2.3	Additional License Grants.

2.9	HSR Act.

(a) HSR Filings. If Spark reasonably determines in good faith prior to the exercise of an Option for a Potential Target that the exercise of such Option requires HSR Clearance under the HSR Act, Spark shall provide written notice of such determination to Selecta in its notice of exercise such Option for such Potential Target. If HSR Filings are required, each Party shall use Commercially Reasonable Efforts to prepare and file its respective HSR Filing as promptly as is practicable.

(b) Tolling of Option Exercise and Payment Obligations. If the exercise by Spark of any Option requires the making of filings under the HSR Act, then all rights and obligations related to the exercise of such Option for the applicable Potential Target (including payment of any Option Exercise Payment) shall be tolled until HSR Clearance for such Option exercise.

(c) Termination. If the Parties make an HSR Filing with respect to an exercise of an Option for a Potential Target pursuant to Section 2.9(a) (HSR Filings) and HSR Clearance for such Option exercise has not occurred on or prior to one hundred eighty (180) days after the effective date of the latest HSR Filing made by the Parties with respect to such Option exercise, then the Option exercise will be revoked and such Potential Target will no longer be a Potential Target for all purposes under this Agreement at the election of either Party immediately upon notice to the other Party, if (a) any Antitrust Authority has instituted (or threatened to institute) any action, suit or proceeding including seeking, threatening to seek or obtaining a preliminary injunction under the HSR Act against Selecta and Spark to enjoin or otherwise prohibit the transactions contemplated by this Agreement related to such Option exercise for such Potential Target, or (b) the Parties have not resolved any and all objections of any Antitrust Authority as contemplated by Section 2.9(a) (HSR Filings).

Selecta shall consult with Spark and shall reasonably consider Spark’s views regarding the desirability and conduct of any such Enforcement Action to the extent such Enforcement Action has aspects relating to a Licensed Product. If Selecta does not undertake such an Enforcement Action within [***] after Spark has notified Selecta of the Third Party Infringement, Declaratory Judgment Action or Third Party Challenge and requested that Selecta bring such Enforcement Action, then the Selecta Background Patent subject to such Third Party Infringement, Declaratory Judgment Action or Third Party Challenge shall no longer be deemed a Selecta Background Patent for the determination of any Royalty Term or for the purposes of Section 6.10(b) (Royalty Adjustments).

(e) Infringement of Spark Patents. If any Patent included in the Spark IP is implicated by the Third Party Infringement, Declaratory Judgment Action or Third Party Challenge, Spark shall have the sole right (but not the obligation) to undertake an Enforcement Action as to such Patent, at its sole expense. Spark shall consult with Selecta and shall reasonably consider Selecta’s views regarding the desirability and conduct of any such Enforcement Action to the extent such Enforcement Action could affect the patent protection for any Licensed Particle.

(f) Cooperation. Each Party shall reasonably cooperate, at the other Party’s expense, with the Party taking an Enforcement Action including joining as a party to such Enforcement Action as may be necessary or desirable for purposes of standing or establishing damages.

8.1

Confidentiality; Exceptions. Except to the extent expressly authorized by this Agreement or otherwise agreed by the Parties in writing, during the term of this Agreement and for [***] thereafter and, with respect to any Confidential Information that is Know-How Controlled by Selecta and related to the Manufacture of any Licensed Particle, for so long as such Confidential Information remains a trade secret, the Parties agree that the receiving Party shall keep confidential and shall not publish or otherwise disclose or use for any purpose other than as provided for in this Agreement any Confidential Information furnished to it by the other Party pursuant to this Agreement. For clarity, Confidential Information of a Party shall include all information and materials disclosed by such Party or its designee that (x) if disclosed in writing or other tangible form, is marked as “Confidential,” “Proprietary” or with similar designation at the time of disclosure, (y) if disclosed verbally or in other intangible form, is indicated upon first disclosure as being confidential or (z) by its nature can reasonably be expected to be considered Confidential Information by the recipient. Notwithstanding the foregoing, Confidential Information shall not be deemed to


	include information or materials to the extent that it can be established by written documentation by the receiving Party that such information or material:

(a) was already known to or possessed by the receiving Party, other than under an obligation of confidentiality (except to the extent such obligation has expired or an exception is applicable under the relevant agreement pursuant to which such obligation established), at the time of disclosure;

(b) was generally available to the public or otherwise part of the public domain at the time of its first disclosure to the receiving Party;

(c) became generally available to the public or otherwise part of the public domain after its disclosure and other than through any act or omission of the receiving Party in breach of this Agreement;

(d) was independently developed by the receiving Party as demonstrated by documented evidence prepared contemporaneously with such independent development; or

8.3	Injunctive Relief. Given the nature of the Confidential Information and the competitive damage that would result to a Party upon unauthorized disclosure, use or transfer of its Confidential Information to any Third Party, the Parties agree that monetary damages may not be a sufficient remedy for any breach of this ARTICLE 8 (Confidentiality). In addition

to all other remedies, a disclosing Party shall be entitled to seek specific performance and injunctive and other equitable relief as a remedy for any breach or threatened breach of this ARTICLE 8 (Confidentiality).


8.4	Terms of Agreement.

(a) The Parties shall treat the existence and material terms of this Agreement (including the Potential Target List) as confidential and shall not disclose such information to Third Parties without the prior written consent of the other Party or except as provided in Section 8.2 (Authorized Use and Disclosure) or Section 8.4(b) (Terms of Agreement). With respect to complying with the disclosure requirements of Securities Laws applicable to a Party, the Parties shall consult with each other concerning which terms of this Agreement shall be requested to be redacted in any public disclosure of the Agreement by the agency, and each Party shall seek confidential treatment, to the extent available, from the agency in public disclosure of the Agreement for all sensitive commercial, financial and technical information, including any dollar amounts set forth herein.

(b) Either Party may disclose to bona fide potential investors, lenders, acquirors and acquirees, and to such Person’s consultants and advisors, the existence and terms of this Agreement to the extent necessary in connection with a proposed equity or debt financing of such Party, or a proposed acquisition or business combination, or to bona fide potential sublicensees, so long as such recipients are bound in writing to maintain the confidentiality of such information in accordance with the terms of this Agreement.

8.5

Publications. Spark and its Affiliates shall have the right to publish or publicly disclose the results generated in the course of performing any research related to a Licensed Product, provided that Spark submits the proposed publication or disclosure to Selecta for its review (a) in the case of any press release or presentation at a conference, at least [***] prior to public disclosure or such shorter period as may be required under applicable Law, (b) in the case of publication of an abstract, at least [***] prior to the scheduled publication or (c) in all other cases, at least [***] prior to the scheduled submission of such proposed publication or public disclosure (including to any journal for review). If, during its [***] review period, as applicable, Selecta notifies Spark that it desires changes to the publication or public disclosure reasonably necessary to protect Selecta IP, Spark shall use reasonable efforts to accommodate such request. If, during its [***] review period, as applicable, Selecta notifies Spark that such publication or public disclosure contains the Confidential Information of Selecta, Spark will remove any such Confidential Information prior to submission. Without limiting Selecta’s right to publish or publicly disclose information and results relating to the Licensed Particles that is not Confidential Information of Spark, Selecta shall not publish or publicly disclose any information or results generated in the course of performing any research related to the Licensed Products without the prior written consent of Spark.

TERM AND TERMINATION


9.1	Term. This Agreement is effective as of the Effective Date and shall continue in full force and effect unless earlier terminated by a Party in accordance with Section 9.2 (Termination) and shall expire on a Licensed Product-by-Licensed Product and country-by-country basis upon the expiration of the Royalty Term with respect to such Licensed Product in such country.


9.2	Termination.

(a) Convenience. Spark may terminate this Agreement in its entirety or with respect to any Target upon ninety (90) days’ prior written notice to Selecta (the “Notice Period”), for any or no reason, without liability to Selecta. For the avoidance of doubt, after giving Selecta notice of its intent to terminate this Agreement pursuant to this Section 9.2(a), Spark shall not be required to make any payments to Selecta for achievement within the Notice Period of any milestone set forth in Section 6.4 (Development Milestones), 6.5 (Regulatory Milestones) or 6.6 (Commercial Milestones).

(b) Material Breach.

(i) Either Party may terminate the Agreement on a Target-by-Target basis in the event of an uncured material breach by the other Party of its obligations under this Agreement (other than a breach by Spark of any payment obligation or Diligence Obligation (defined below) hereunder) with respect to such Target, in each case, by giving written notice to the other Party specifying the nature of the material breach. If such breach has been cured by such breaching Party within [***] after the date of such notice (the “Cure Period”), such termination shall not occur. If such breach has not been cured by the breaching Party within the Cure Period, then the non-breaching Party shall be entitled to terminate this Agreement with respect to such Target with immediate effect upon delivery to the breaching Party of a written notice of termination; provided, however, that if the Party accused of materially beaching notifies the accusing Party in writing (i) within the Cure Period, that the accused Party disputes that it is in material breach, or (ii) within [***] after delivery by the accusing Party of a termination notice following the expiration of the Cure Period, based on the accused Party’s failure to cure a material breach, the accused Party contends that it cured such material breach within the Cure Period and, in either such case, initiates the dispute resolution procedure set forth in ARTICLE 12 (Dispute Resolution) within such Cure Period or such [***] period (as applicable), then no such termination shall become effective until a final, binding determination pursuant to ARTICLE 12 (Dispute Resolution) that the accused Party was in material breach and failed to cure such material breach during the Cure Period.

(ii) Selecta may terminate this Agreement on a Target-by-Target basis with respect to the applicable Target, in the event of an uncured breach by Spark of any of its payment obligations under this Agreement with respect to such Target (excluding Spark’s obligations to make Scheduled Payments in accordance with Section 6.1 (Scheduled Payments)) by giving written notice to Spark specifying the nature of the breach. If such breach has been cured by Spark within [***] of such notice in the case of a payment breach (the “Payment Cure Period”), such termination shall not occur. If such breach has not been cured by Spark within the Payment Cure Period, then Selecta shall be entitled to terminate this Agreement with respect to such Target with immediate effect upon delivery to Spark of a written notice of termination; provided, however, that if Spark notifies Selecta in writing within the Payment Cure Period that Spark disputes that it is in breach of a payment obligation and initiates the dispute resolution procedure set forth in ARTICLE 12 (Dispute Resolution) within such Payment Cure Period, then no such termination shall become effective until [***] after a final, binding resolution of such dispute (and determination of the full amount due to Selecta) pursuant to ARTICLE 12 (Dispute Resolution); provided that, if Spark pays Selecta the full amount due within such [***] period, such termination shall not occur. If Selecta terminates this Agreement with respect to a Target pursuant to this Section 9.2(b)(ii) and Spark subsequently breaches any of its payment

obligations under this Agreement with respect to a second Target (excluding Spark’s obligations to make Scheduled Payments in accordance with Section 6.1 (Scheduled Payments)), then Selecta will be entitled to terminate this Agreement with respect to such Target or in its entirety, subject to the notice and cure period set forth above.

(iii) Selecta may terminate this Agreement, on a Target-by-Target basis with respect to the applicable Target, in the event of an uncured material breach by Spark of its obligations under Section 3.2 (Development Diligence) or Section 4.1 (Commercial Diligence) with respect to such Target (“Diligence Obligations”) in (1) the United States if such breach relates to the United States, (2) the European Union if such breach relates to the European Union, (3) Japan if such breach relates to Japan and (4) in all countries other than Japan if such breach relates to both the United States and the European Union, in each case by giving written notice to Spark specifying the nature of the breach. If such breach has been cured by Spark within [***] of such notice in the case of a breach of Diligence Obligations (the “Diligence Cure Period”), such termination shall not occur. If such breach has not been cured by Spark within the Diligence Cure Period, then Selecta shall be entitled to terminate this Agreement with respect to such Target and such jurisdiction(s) with immediate effect upon delivery to Spark of a written notice of termination; provided, however, that if Spark notifies Selecta in writing within the Diligence Cure Period that Spark disputes that it is in breach of its Diligence Obligations and initiates the dispute resolution procedure set forth in ARTICLE 12 (Dispute Resolution) within such Diligence Cure Period, then no such termination shall become effective until a final, binding determination pursuant to ARTICLE 12 (Dispute Resolution) that Spark was in material breach and failed to cure such material breach during the Diligence Cure Period.

(c) Bankruptcy. Either Party may terminate the Agreement if the other Party makes a voluntary or involuntary general assignment of its assets for the benefit of creditors, a petition in bankruptcy is filed by or against the other Party and is not dismissed in ninety (90) days, or a receiver or trustee is appointed for all or any part of the other Party’s property.

(d) Termination for Patent Challenge.

(i) In the event that Spark or any of its Affiliates or sublicensees, individually or in association with any other Person, initiates or assists in initiating or continuing a challenge to the validity, patentability, enforceability or non-infringement of any Selecta Background Patent (other than any MIT Patent) or Selecta-Invented Improvement Patent, or otherwise opposes any such Patent through any administrative, judicial or other similar proceeding with respect to such Patent and such challenge or opposition to such Patent is unsuccessful, Selecta may terminate this Agreement in its entirety on thirty (30) days’ notice. The foregoing shall not apply with respect to (i) any Patent challenge described above that is made in defense of Selecta’s assertion of any Selecta Patent right

against Spark or any of its Affiliates or sublicensees with respect to any product or technology other than Licensed Particles or (ii) any patent challenge commenced by a Third Party that after the Effective Date acquires or is acquired by Spark or any of its Affiliates or sublicensees or its or their business or assets, whether by stock purchase, merger, asset purchase or otherwise, provided that such patent challenge commenced prior to the signing of the acquisition or merger agreement relating to such acquisition.

(ii) In the event that Spark or any of its Affiliates or sublicensees, individually or in association with any other Person, initiates or assists in initiating or continuing a challenge to the validity, patentability, enforceability or non-infringement of any MIT Patent or otherwise opposes any such MIT Patent through any administrative, judicial or other similar proceeding with respect to such MIT Patent, Selecta may terminate this Agreement with respect to the MIT Patents on thirty (30) days’ notice to Spark and the MIT Patents will thereafter be excluded from the Selecta Background Patents for all purposes under this Agreement.

(e) Termination for Failure to Make Scheduled Payment. If Spark fails to make any Scheduled Payment in accordance with Section 6.1 (Scheduled Payments), then Selecta may give written notice to Spark notifying Spark that Selecta intends to terminate this Agreement pursuant to this Section 9.2(e). If Selecta provides such notice, then unless Spark makes the applicable Scheduled Payment within five (5) days after delivery of Selecta’s written termination notice, this Agreement shall automatically terminate in its entirety effective upon the expiration of such five (5) day period.

INDEMNIFICATION, INSURANCE AND LIABILITY

11.1

Indemnification by Selecta. Selecta shall defend, indemnify and hold harmless Spark, its Affiliates and its and their officers, directors, employees, agents, representatives, successors and assigns (each, a “Spark Indemnitee”) from and against any losses, liability or expense (including reasonable legal expenses, costs of litigation and attorneys’ fees), damages, or judgments, whether for money or equitable relief (collectively, “Losses”) resulting from

suits, proceedings, claims, actions, demands, or threatened claims, actions or demands, in each case brought by a Third Party (each, a “Claim”) against a Spark Indemnitee arising out of: (a) (i) any negligent act or omission, or willful wrongdoing by Selecta or its Affiliates in the performance of this Agreement, (ii) the failure by Selecta to comply with any Law, (iii) any breach of any representation or warranty or covenant of Selecta under this Agreement, except, in each case, to the extent any such Losses result from the gross negligence or willful misconduct of a Spark Indemnitee or from the breach of any representation or warranty or obligation under this Agreement by Spark, or (b) or resulting from any Claim against a Spark Indemnitee or against Selecta asserting that [***].

11.2

Indemnification by Spark. Spark shall defend, indemnify and hold harmless Selecta and its Affiliates and its and their officers, directors, employees, agents, representatives, successors and assigns, the licensors under the In-License Agreements and their respective directors, officers, employees and agents and the MIT Indemnitees (each, a “Selecta Indemnitee”) from and against any and all Losses resulting from Claims, including bodily injury, risk of bodily injury, death, property damage and product liability, against any Selecta Indemnitee arising out of or relating to, directly or indirectly: (a) any negligent act or omission, or willful wrongdoing by Spark or any of its Affiliates or sublicensees in the performance of this Agreement, (b) the failure by Spark any of its Affiliates or sublicensees to comply with any Law, (c) any alleged personal injuries or death resulting from, arising out of or relating to any Clinical Trials or use of a Licensed Product sponsored or distributed by or on behalf of Spark or its Affiliates or sublicensees, (d) any breach of any representation or warranty or covenant of Spark under this Agreement or (e) the exercise of any rights granted to Spark under this Agreement; except, in each case, to the extent any such Losses result from the gross negligence or willful misconduct of a Selecta Indemnitee or from the breach of any representation or warranty or obligation under this Agreement by Selecta.

11.3

Limitations on Indemnification. The obligations to indemnify, defend, and hold harmless set forth in Sections 11.1 (Indemnification by Selecta) and 11.2 (Indemnification by Spark) shall be contingent upon the Party seeking indemnification (the “Indemnitee”): (a) notifying the indemnifying Party of a claim, demand or suit within [***] of receipt of same; provided, however, that Indemnitee’s failure or delay in providing such notice shall not relieve the indemnifying Party of its indemnification obligation except to the extent the indemnifying Party is prejudiced thereby; (b) allowing the indemnifying Party or its insurers the right to assume direction and control of the defense of any claim, demand or suit; (c) using its best efforts to cooperate with the indemnifying Party or its insurers, at the indemnifying Party’s expense, in the defense of such claim, demand or suit; and (d) not settling or compromising any claim, demand or suit without prior written authorization of the indemnifying Party (not to be unreasonably withheld).

in the defense of such claim, demand or suit; provided that the indemnifying Party shall bear the reasonable fees, costs and expenses of one such separate counsel and participation if the Indemnitee shall have reasonably determined, after consultation with counsel, that an actual or potential conflict of interest makes representation by the same counsel or the counsel selected by the indemnifying Party inappropriate.


11.4	Offset. Following the determination of Losses subject to indemnification under Section 11.1 (Indemnification by Selecta) or 11.2 (Indemnification by Spark) by a court of competent jurisdiction, the Indemnitee shall have a right to offset such Losses against any payment due to the indemnifying Party hereunder.

11.5

In no event shall any Party be liable to the other Party for any indirect, special, incidental, exemplary or consequential damages of any kind arising out of or in connection with this Agreement, however caused and on any theory of liability (whether in contract, tort (including negligence), strict liability or otherwise), even if such Party was advised or otherwise aware of the likelihood of such damages. The limitations set forth in this Section 11.5 shall not apply with respect to (a) the Party’s indemnification obligations under Sections 11.1 (Indemnification by Selecta) or 11.2 (Indemnification by Spark), as applicable, (b) breach of ARTICLE 8 (Confidentiality), or (c) intentional misconduct of a Party. Nothing in this Section 11.5 shall limit a Party’s liability for death or injury caused by that Party’s negligence, or fraud or fraudulent misrepresentation.

11.6

Insurance. During the term of this Agreement, each Party shall obtain and maintain commercial general liability insurance with a reputable, solvent insurer in an amount appropriate for its business and products of the type that are the subject of this Agreement, and for its obligations under this Agreement and shall obtain and maintain product liability insurance and clinical trial liability insurance with limits of at least [***] per occurrence and in annual aggregate.

Spark Therapeutics Enters into Licensing Agreement with Selecta Biosciences

Exclusive use of Selecta’s Synthetic Vaccine Particles (SVP™) platform technology provided to Spark Therapeutics for co-administration with up to five gene therapy targets, including FVIII for hemophilia A

SVP may enhance gene therapies by enabling repeat dosing and mitigating other potential immune responses to an AAV capsid

PHILADELPHIA, PA and WATERTOWN, MA, Dec. 5, 2016 -- Spark Therapeutics (NASDAQ: ONCE) and Selecta Biosciences, Inc. (NASDAQ: SELB) today announced a license agreement that provides Spark Therapeutics with exclusive worldwide rights to Selecta’s proprietary Synthetic Vaccine Particles (SVP™) platform technology for co-administration with gene therapy targets, including FVIII for hemophilia A, as well as exclusive options for up to four additional undisclosed genetic targets.

Selecta’s immune tolerance SVP, including SVP-Rapamycin, is an investigational technology intended to suppress the formation of neutralizing antibodies to an adeno-associated virus (AAV) capsid when used in combination with gene therapies, without altering the therapeutic profile of the gene therapy. Neutralizing antibodies form in response to an initial administration of an AAV gene therapy and prevent effective subsequent usage. The potential ability to re-dose a gene therapy may be beneficial where a patient has not achieved a sufficient therapeutic expression of the transferred gene in the initial dose.

“Selecta’s nanoparticle technology, which is undergoing preclinical testing in gene therapy, may prevent formation of neutralizing antibodies, and thus potentially enable re-dosing up to an optimal therapeutic profile by extending the reach of gene therapy to diseases that require higher doses or more extensive transduction of target cells than may be achieved through one-time dosing,” said Xxxxxxx X. Xxxxxxxx, chief executive officer of Spark Therapeutics. “Importantly, if proven successful, the co-administration of Selecta’s technology with a gene therapy may enable repeat dosing of AAV gene therapies in both adults and pediatric patients, potentially minimizing the risk of a T-cell immune response to the capsid.”

“Gene therapy is a core area of focus for Selecta; one that we believe could benefit profoundly from our immune tolerance SVP technology platform,” said Xxxxxx Xxxxxxxxx, Ph.D., president, CEO and chairman of Selecta. “We are excited about this license agreement with Spark Therapeutics, a recognized gene

therapy leader, which accelerates the application of our SVP platform in gene therapy. Our preclinical studies in this field, together with the clinical data we have generated with SEL-212 in gout showing prevention of anti-drug antibodies, suggest that the application of our immune tolerance SVP technology to biologic therapies may greatly benefit patients with life-threatening diseases who currently lack adequate treatment options due to the occurrence of undesired immune responses.”

Subject to the terms of the agreement, Spark Therapeutics will make an initial $10 million cash payment to Selecta and purchase $5 million of Selecta’s common stock. Within 12 months of the agreement’s signing, Spark Therapeutics has agreed to pay Selecta an additional $5 million in cash and to purchase $10 million of Selecta’s common stock. Selecta will be eligible for up to $430 million in milestone payments for each target, with up to $65 million being based on Spark Therapeutics’ achievement of specified development and regulatory milestones and up to $365 million for specified commercial milestones. In addition, Spark Therapeutics will pay Selecta tiered mid-single to low-double-digit royalties on worldwide annual net sales of any resulting commercialized gene therapy.

The terms of this agreement do not apply to Spark Therapeutics’ ongoing investigational development programs in inherited retinal diseases (IRDs), including voretigene neparvovec for the treatment of RPE65-mediated IRD and SPK-7001 for choroideremia. This agreement does not impact Spark Therapeutics’ ongoing Phase 1/2 trial of SPK-9001 in hemophilia B in collaboration with Pfizer or its planned Phase 1/2 trial of SPK-8011 in hemophilia A.

Selecta independently is applying its SVP technology to its own proprietary gene therapy programs. Selecta has obtained an exclusive license from Massachusetts Eye and Ear to Anc80, an in silico-designed gene therapy vector, for Methylmalonic Acidemia and has options for additional pre-defined indications. Additionally, Selecta is advancing a proprietary gene therapy program for Ornithine Transcarbamylase Deficiency.

About Spark Therapeutics

Spark Therapeutics, a fully integrated company, is striving to challenge the inevitability of genetic disease by discovering, developing, and delivering gene therapies that address inherited retinal diseases (IRDs), liver-mediated diseases such as hemophilia, and neurodegenerative diseases. Our validated platform successfully has delivered proof-of-concept data with investigational gene therapies in the retina and liver. Our most advanced investigational candidate, voretigene neparvovec, in development for the treatment of RPE65-mediated IRD, has received orphan designations in the U.S. and European Union, and breakthrough therapy designation in the U.S. The pipeline also includes SPK-7001, in a Phase 1/2 trial for choroideremia, and two hemophilia development programs: SPK-9001 in a Phase 1/2 trial for hemophilia B being developed in collaboration with Pfizer (which also has received both breakthrough therapy and orphan product designations) and SPK-8011, a preclinical candidate for hemophilia A to which Spark Therapeutics retains global commercialization rights.

About Selecta Biosciences, Inc.

Selecta Biosciences, Inc. is a clinical-stage biopharmaceutical company developing targeted therapies that use immunomodulators encapsulated in nanoparticles to induce antigen-specific immune responses to prevent and treat disease. Selecta’s proprietary Synthetic Vaccine Particles (SVP™) technology is a highly flexible nanoparticle platform capable of incorporating a wide range of antigens and immunomodulators, allowing SVP-based products to either induce antigen-specific tolerance or activate the immune system. Selecta’s focus and strategy is to leverage its SVP immune modulating platform to develop and commercialize highly differentiated life-sustaining biologic drugs that are uniquely capable of mitigating the formation of anti-drug antibodies (ADAs). Proprietary programs that use SVP-Rapamycin to enhance efficacy and safety of therapy include SEL-212, Selecta’s lead Phase 2 clinical program in chronic refractory gout, and two gene therapies programs for genetic metabolic diseases. Tolerance-inducing SVP biological products also have potential applications in the treatment of allergies and autoimmune diseases. Selecta is also developing SVP product candidates that activate the immune system to prevent and treat cancer, infections and other diseases. Selecta is based in Watertown, Massachusetts, USA.
