Section 7.Adverse Events; Pharmacovigilance; Recalls.

7.1 Adverse Event Reporting. Each Party will provide the other Party with all information available to such Party that such other Party may reasonably require to comply with its pharmacovigilance responsibilities under applicable Law, including notice of any Adverse Drug Experiences from pre-clinical or clinical laboratory, animal toxicology and pharmacology studies, Clinical Studies and commercial experiences with any Licensed Compound or Licensed Product, whether by such Party, its Affiliates or, in the case of Selecta, its Sublicensees. “Adverse Drug Experience” means (a) any finding from tests in laboratory animals or in vitro that suggests a significant risk for human subjects including reports of mutagenicity, teratogenicity or carcinogenicity and (b) any undesirable, untoward or noxious event or experience associated with the clinical, commercial or other use, or occurring following administration, of any Licensed Compound or Licensed Product in humans, occurring at any dose, whether expected or unexpected and whether considered related or unrelated to any Licensed Compound or Licensed Product, including such an event or experience as occurs in the course of the use of any Licensed Compound or Licensed Product in professional practice, in a clinical trial, from overdose, whether accidental or intentional, from abuse, from withdrawal or from a failure of expected pharmacological or biological therapeutic action of any Licensed Compound or Licensed Product, and including those events or experiences that are required to be reported to the FDA under 21 C.F.R. Sections 312.32 or 314.80, or to foreign Regulatory Authorities under corresponding applicable Law outside the United States.

7.2 Pharmacovigilance. Subject to the terms and conditions of this Agreement, within [***] months of the Original Effective Date, 3SBio and Selecta will discuss and develop mutually acceptable guidelines and procedures for the investigation, exchange, receipt, recordation, communication (as between the Parties) and exchange of Adverse Drug Experience information and all other information regarding matters covered in this Section 7. Until such guidelines and procedures are set forth in such pharmacovigilance agreement, the terms of Section 7 will apply. Following the execution of the pharmacovigilance agreement, Section 7 will cease to apply unless expressly agreed otherwise by the Parties. Such pharmacovigilance agreement will include provisions for the direct and prompt reporting of adverse events to Selecta in the English language by 3SBio employees or representatives and vice versa, the recording and maintenance by Selecta of records of all adverse events reported with respect to any Licensed Compound or the Licensed Product in the Field on a

worldwide basis in an electronic database, and the establishment of appropriate mechanisms by which 3SBio can access such database on a read only basis to comply with applicable Law and to perform its responsibilities and exercise its rights under this Agreement; provided, however, that Selecta will not assume any regulatory compliance responsibilities of 3SBio with respect to pharmacovigilance outside the Territory by virtue of its establishment and maintenance of such global database. Selecta will bear all costs incurred in connection with receiving, recording, reviewing, communicating, reporting and responding to adverse events in the Territory, and 3SBio will bear all costs incurred in connection with the same outside the Territory; provided, however, that Selecta will establish and maintain such global database at its sole cost and expense.

7.3 Notification and Recall. In the event that any Regulatory Authority issues or requests a recall or takes similar action in connection with a Licensed Product or in the event either Party determines that an event, incident or circumstance has occurred that may result in the need for a recall or market withdrawal, the Party notified of or desiring such recall or similar action will, within twenty-four (24) hours, advise the other Party thereof by telephone (and confirmed by email or facsimile), email or facsimile. Selecta will have the sole right to decide, in its discretion, whether to conduct a recall, at its expense, of a Licensed Product in the Territory, and the manner in which any such recall will be conducted. 3SBio will have the sole right to decide, in its discretion, whether to conduct a recall, at its expense, of a Licensed Product outside the Territory, and the manner in which any such recall will be conducted.

7.4 Recall Expenses. Selecta will bear the expenses of any recall of a Licensed Product in the Territory; provided, however, that 3SBio will bear the expense of a recall to the extent that such recall resulted from 3SBio’s breach of its obligations hereunder. 3SBio will bear the expenses of any recall of a Licensed Product outside the Territory; provided, however, that Selecta will bear the expense of a recall to the extent that such recall resulted from Selecta’s breach of its obligations hereunder.

Section 8.Payments by Selecta.

8.1 Upfront Fee. The Parties hereby acknowledge and agree that as of the Effective Date, Selecta has paid to 3SBio (or its designated Affiliate) the following non-refundable, non-creditable payments: (a) US$500,000 within [***] business days after the Original Effective Date; and (b) US$500,000 within [***]. For purposes of this Agreement, “commencement” means (i) [***]; and (ii) [***].

8.2 Milestone Payments. As set forth in the following table, Selecta will make the following non-refundable Development milestone payments to 3SBio, or a designated Affiliate, upon achievement of each of the Development milestone events. Each milestone payment will be payable by Selecta to 3SBio within [******] after the Calendar Quarter in which the achievement of the corresponding milestone event with respect to the first Product occurs. Separate milestone payments, as set forth in the table below, are due if Selecta chooses to Develop both Licensed Products and Selecta Products. Each milestone, however, is payable one time only no matter how many times any of the milestone events are achieved.



Milestone Event	Milestone Payment
	If Selecta elects to Develop Licensed Products under Section 5.1(d)	If Selecta elects to Develop Selecta Products under Section 5.1(d)
1. [***]	US$[***]
2. [***]	US$[***]	US$[***]
3. [***]	US$[***]	US$[***]
4. [***]	US$[***]	US$[***]
5. [***]	US$[***]	US$[***]

8.3 Royalties.

(a)Royalties. Selecta will pay to 3SBio, or a designated Affiliate, royalties based on annual worldwide Net Sales, on a country-by-country and Product-by-Product basis, at the royalty rate specified in the following table.



Annual Worldwide Net Sales of All Products in a Calendar Year	Royalty Rate
	% if Selecta elects to Develop Licensed Products under Section 5.1(d)	% if Selecta elects to Develop Licensed Products under Section 5.1(d)
On such Net Sales up to US$[***]	[***]%	[***]%
On such Net Sales above US$[*] and up to US$[*]	[***]%
On such Net Sales above US$[*] and up to US$[*]	[***]%
On such Net Sales above US$[***]	[***]%

(b)Royalty Term. Selecta’s obligation to pay royalties under Section 8.3(a) will be in effect during the “Royalty Period” which begins on [***] and will expire on a Product-by-Product and country-by-country basis upon the later of:

(i)the expiration of the last-to-expire of any 3SBio Patent Right in such country having a Valid Claim that covers such Product and that would be infringed by the sale of such Product in such country; or

(ii)[***] after the First Commercial Sale of such Product in such country;

provided that, with respect to Net Sales of a Product in a given country, for the period of time (if any) that the Royalty Period for such Product in such country is based on clause (ii) above and not on clause (i) above, then the royalty rates set forth in the table above will be reduced by [***] percent ([***]%) from the rates set forth in the above table.

(c)Only One Royalty. Only one royalty will be due with respect to the sale of the same unit of Product. Only one royalty will be due hereunder on the sale of a Product even if the manufacture, use, sale, offer for sale or importation of such Product infringes more than one claim of the 3SBio Patent Rights.

(d)Compulsory Licenses. If a compulsory license is granted to a Third Party with respect to a Product in any country or region in the Territory with a royalty rate that is lower than the royalty rate payable to 3SBio under Section 8.3, then the royalty rate to be paid by Selecta on Net Sales of Product in that country pursuant to Section 8.3 will be reduced to the royalty rate paid to Selecta by the compulsory licensee.

8.4 Royalty Stacking. Selecta will be entitled to deduct, from the royalties otherwise due in respect of Net Sales of Products, all Related Third Party Payments (as defined below) paid or payable by Selecta or any of its Affiliates or Sublicensees in respect of such Products; provided, however, in no event will a deduction under this Section 8.4 reduce any royalty payments to be made by Selecta by more than [***] percent ([***]%) for any Calendar Quarter; and provided, further, any reduction hereunder, or portion thereof, that is rendered not usable pursuant to the immediately preceding proviso may be carried forward for use in a future Calendar Quarter. For purposes of this Agreement, “Related Third Party Payments” mean any and all payments to a Third Party to license, sublicense, acquire or otherwise access Patent, Know-How or other intellectual property rights if, in the absence of such license, sublicense, acquisition or access, the making, using, selling, offering for sale, importation, researching, Developing, distribution, Commercializing or exploitation of a Licensed Compound or Product would or is likely to, in the reasonable judgment of Selecta, infringe or misappropriate such Patent Rights, Know-How or other intellectual property rights.

8.5 Royalty Reductions. Notwithstanding the application of royalty offsets or reductions that are permitted pursuant to this Agreement, in no event will the royalties paid by Selecta to 3SBio for any Calendar Quarter during the Royalty Period be less than [***] percent ([***]%) of annual worldwide Net Sales, on a country-by-country and Product-by-Product basis.

8.6 Payment Terms.

(a) Manner of Payment. All payments to be made by Selecta hereunder will be made in U.S. dollars by wire transfer to such bank account as 3SBio may designate.

(b) Reports and Royalty Payments. For as long as royalties are due under Section 8.3(a), Selecta will furnish to 3SBio a written report, within [***] after the end of each Calendar Quarter, showing the amount of Net Sales of Products and royalty due for such Calendar Quarter. Royalty payments for each Calendar Quarter will be due at the same time as such written report for the Calendar Quarter. The report will include, at a minimum, the following information for the applicable Calendar Quarter, each listed by product and by country of sale: (i) the number of units of Products sold by Selecta and its Affiliates and Sublicensees on which royalties are owed 3SBio hereunder; (ii) the gross amount received for such sales; (iii) deductions taken from Net Sales as specified in the definition thereof; (iv) Net Sales; (v) the amounts of any credits or reductions permitted by Section 8.4 or elsewhere hereunder; (vi) the royalties and Milestone Payments owed to 3SBio, listed by category; and (vii) the computations for any applicable currency conversions pursuant to Section 8.6(d). Selecta will use commercially reasonable efforts to obtain permission from each Sublicensee to share with 3SBio the information listed in the foregoing clauses (other than clause (iv)) as it relates to Net Sales made by such Sublicensee, and to the extent successful, will include such Sublicensee information in such report. All such reports will be treated as Confidential Information of Selecta.

(c) Records and Audits. Selecta will keep, and will cause each of its Affiliates and Sublicensees, as applicable, to keep adequate books and records of accounting for the purpose of calculating all royalties payable to 3SBio hereunder. For the [***] following the end of the Calendar

Year to which each will pertain, such books and records of accounting (including those of Selecta’s Affiliates or Sublicensees, as applicable) will be kept at each of their principal place of business and will be open for inspection at reasonable times and upon reasonable notice by an independent certified accountant selected by 3SBio, and which is reasonably acceptable to Selecta, for the sole purpose of inspecting the royalties due to 3SBio under this Agreement. In no event will such inspections be conducted hereunder more frequently than once every [***] months. Such accountant must have executed and delivered to Selecta and its Affiliates or Sublicensees, as applicable, a confidentiality agreement as reasonably requested by Selecta, which will include provisions limiting such accountant’s disclosure to 3SBio to only the results and basis for such results of such inspection. The results of such inspection, if any, will be binding on both Parties. Any underpayments will be paid by Selecta within [***] days of notification of the results of such inspection. Any overpayments will be fully creditable against amounts payable in subsequent payment periods. 3SBio will pay for such inspections, except that in the event there is any upward adjustment in aggregate royalties payable for any Calendar Year shown by such inspection of more than [***] percent ([***]%) of the amount paid, Selecta will reimburse 3SBio for any reasonable out-of-pocket costs of such accountant. Any underpayments or overpayments under this Section 8.6(c) will be subject to the currency exchange provisions set forth in Section 8.6(d) as applied to the Calendar Quarter during which the royalty obligations giving rise to such underpayment or overpayment were incurred by Selecta.

(d) Currency Exchange. With respect to Net Sales invoiced in U.S. dollars, the Net Sales and the amounts due to 3SBio hereunder will be expressed in U.S. dollars. With respect to Net Sales invoiced by Selecta, its Affiliates and assignees in a currency other than U.S. dollars, the Net Sales will be expressed in the domestic currency of the entity making the sale, together with the U.S. dollar equivalent, calculated using the official rate of exchange of such domestic currency as quoted by the Wall Street Journal or other equivalent publication for the last day of the Calendar Quarter in which such sales occurred.

(e)Tax Withholding.

(i)Selecta will pay all taxes and levies that by applicable Laws (including existing treaties for bilateral taxation) Selecta is required to pay on payments accruing under this Agreement and will withhold from sums payable to 3SBio only such taxes and levies as required by Law under penalty. Selecta will forward to 3SBio documentation evidencing such payments whenever possible. To the extent that Selecta withholds any taxes or levies on payments to 3SBio, 3SBio agrees that Selecta will not be obligated to gross-up any such amounts and 3SBio waives any right to payment from Selecta with respect to the withheld amounts. However, if Selecta receives a refund of any taxes or levies withheld from amounts payment to 3SBio under this Agreement, Selecta will pay to 3SBio an amount equal to such refund net of all out-of-pocket expenses and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund).

(ii)The Parties will cooperate with respect to tax matters relating to this Agreement including by providing an IRS Form W-9 or IRS Form W-8BEN (or other such form demonstrating an exemption from applicable taxes or levies as may be reasonably requested by the other Party), provided that such Party is legally entitled to do so. If any IRS Form expires or becomes obsolete or inaccurate in any respect, the Party that provided such form will promptly (and in any event within thirty (30) days after such expiration, obsolescence, or inaccuracy) notify the other Party in writing of such expiration, obsolescence, or inaccuracy and update the IRS Form if it is legally eligible to do so.

(iii)In the event that any taxes or levies are assessed against Selecta with respect to payments made to 3SBio under this Agreement, such taxes or levies (plus any penalties interest, or other charges imposed by the relevant Governmental Authority not related to any delinquency by Selecta) will be paid by 3SBio. Should Selecta have to pay such taxes or levies 3SBio will promptly reimburse Selecta in full for any taxes or levies (plus any penalties, interest, or other charges imposed by the relevant Governmental Authority not related to any delinquency by Selecta) so paid by Selecta upon receipt of a copy of the assessment. Alternatively, Selecta may reduce the amount of future payments to 3SBio under this Agreement so as to recover in full any such taxes or levies (plus any penalties, interest, or other charges imposed by the relevant Governmental Authority not related to any delinquency by Selecta) so paid by Selecta.

(f)Other Taxes. For clarity, 3SBio will pay, when due, any sales tax, transfer tax, stamp tax and other taxes payable in connection with this Agreement and required by Law and under penalty to be paid by 3SBio. It is understood and agreed between the Parties than any payments made pursuant to this Agreement are inclusive of any value added tax imposed upon such payments.

(g)Set-Off. A Party will be permitted to set off any payments due hereunder against any amounts owed by the other Party to such Party hereunder to the extent permitted by applicable Laws.

(h)Interest Due. Selecta will pay 3SBio interest on any payments that are not paid on or before the date such payments are due under this Agreement at a rate of [***] percent ([***]%) per [***] or the maximum applicable legal rate, if less, calculated on the total number of days payment is delinquent.

Section 9.Patent Prosecution, Infringement and Extensions.

9.1 3SBio Patent Rights.

(a)The Parties will consult with one another regarding the preparation, prosecution (including any interferences, reissue proceedings and reexaminations) and maintenance of 3SBio Patent Rights. Selecta will control and will make all final decisions regarding the filing, prosecution, and maintenance of the 3SBio Patent Rights, worldwide except for Greater China, subject to 3SBio’s consultation right specified above. 3SBio will take all steps required to transfer such control to Selecta, including making such filings as are appropriate with the applicable government patent authority (e.g., in the United States, the U.S. Patent & Trademark Office). Selecta will be responsible for all reasonable out-of-pocket costs and expenses incurred for the preparation, prosecution and maintenance of the 3SBio Patent Rights worldwide, except for Greater China, and 3SBio will be responsible for all reasonable out-of-pocket costs and expenses incurred for the preparation, prosecution and maintenance of the 3SBio Patent Rights in Greater China. Each Party will provide to the other copies of any papers relating to the filing, prosecution or maintenance of 3SBio Patent Rights, with respect to papers received by such Party and with respect to papers to be filed, reasonably sufficiently far enough in advance of filing to allow the other Party to review and comment thereon. Upon request by 3SBio, Selecta will provide 3SBio with an update of the filing, prosecution and maintenance status for each 3SBio Patent Right. Each Party will reasonably cooperate with the other Party in the preparation, prosecution and maintenance of the 3SBio Patent Rights. Such cooperation includes promptly executing all documents, or requiring inventors, subcontractors, employees, consultants and agents of 3SBio and of Selecta and its Affiliates, and Sublicensees, all as described herein to execute all documents, as reasonable and appropriate so as to enable the preparation, prosecution and maintenance

of any such 3SBio Patent Rights in any country. Such cooperation includes promptly executing all documents, or requiring inventors, subcontractors, employees, consultants and agents of 3SBio and of Selecta and its Affiliates, and Sublicensees, all as described herein to execute all documents, as reasonable and appropriate so as to enable the preparation, prosecution and maintenance of any such 3SBio Patent Rights in any country.

(b)In the event that Selecta decides not to continue the prosecution or maintenance of a patent application or patent within 3SBio Patent Rights in any country, Selecta will provide 3SBio with notice of this decision at least [***] days prior to any pending lapse or abandonment thereof, and 3SBio will thereupon have the right, but not the obligation, to assume responsibility for the prosecution and maintenance of such Patents, on a patent-by-patent and country-by-country basis, at its own expense with counsel of its own choice. Promptly upon receipt from 3SBio of written notice of its election to assume such responsibility, Selecta will transfer or cause to be transferred to 3SBio the complete prosecution file for such patent(s), including all correspondence and filings with patent authorities with respect to such patent(s), or sufficient information to allow 3SBio to file such new patent application, whereupon such patent(s) will remain a “3SBio Patent Rights” hereunder, and 3SBio will be solely responsible for all costs and expenses for the filing, prosecution and maintenance of the same.

9.2 Enforcement and Defense.

(a) By Selecta. In the event that 3SBio or Selecta becomes aware of a suspected infringement of any 3SBio Patent Right, or any such 3SBio Patent Right is challenged in any action or proceeding (other than any interferences, oppositions, reissue proceedings or reexaminations, which are addressed above), such Party will notify the other Party promptly, and following such notification, the Parties will confer. Selecta will have the right, but will not be obligated, to defend any such action or proceeding or bring an infringement action with respect to such infringement at its own expense, in its own name and entirely under its own direction and control, or settle any such action or proceeding by sublicense. 3SBio will reasonably assist Selecta in any action or proceeding being defended or prosecuted if so requested, and will be named in and/or join such action or proceeding as Selecta may require or if 3SBio so requests. If 3SBio elects to be represented by the same counsel as Selecta, Selecta will bear all related 3SBio reasonable legal fees.

(b) By 3SBio. If Selecta elects not to settle, defend or bring any action for infringement described in Section 9.2(a) and so notifies 3SBio, then 3SBio may defend or bring such action at its own expense, in its own name and entirely under its own direction and control, subject to the following: Selecta will reasonably assist 3SBio in any action or proceeding being defended or prosecuted if so requested, and will join such action or proceeding if requested by 3SBio or required by applicable law. Selecta will have the right to participate in any such action or proceeding with its own counsel at its own expense and without reimbursement. No settlement of any such action or proceeding which restricts the scope, or adversely affects the enforceability, of a 3SBio Patent Right may be entered into by 3SBio without the prior written consent of Selecta.

(c)Damages. In the event that either Party exercises the rights conferred in this Section 9.1 and recovers any damages or other sums in such action or proceeding or in settlement thereof, such damages or other sums recovered will first be applied to all out-of-pocket costs and expenses incurred by the Parties in connection therewith (including attorney’s fees), unless not reimbursable hereunder. If such recovery is insufficient to cover all such costs and expenses of both Parties, the controlling Party’s costs will be paid in full first before any of the other Party’s costs. If

after such reimbursement any funds will remain from such damages or other sums recovered, such funds will be retained by the Party that controlled the action or proceeding under this Section 9.1; provided, however, that (i) if Selecta is the Party that controlled such action or proceeding, 3SBio will receive out of any such remaining recovery received by Selecta an amount equal to royalties payable hereunder by treating such remaining recovery as “Net Sales” hereunder and (ii) if 3SBio is the Party that controlled such action or proceeding, the remaining recovery received by 3SBio will be shared equally between Selecta and 3SBio. By way of illustration, if Selecta is the Party that controlled such action or proceeding and obtains a recovery as a result, then such recovery will be first be used to pay the costs and expenses incurred by the Parties in connection therewith, and the remainder will deemed to be Net Sales of Selecta and will be included in the calculation of the royalties payable under Section 8.3. If 3SBio is the Party that controlled such action or proceeding and obtains a recovery as a result, then such recovery will be first used to pay the costs and expenses incurred by the Parties in connection therewith, and the remainder will be shared [***] percent ([***]%) to 3SBio and [***] percent ([***]%) to Selecta.

9.3 Third Party IP Claims. In the event of (a) either (i) a holding in any action or proceeding enjoining Selecta or any of its Affiliates or Sublicensees from Manufacturing, using, selling, offering for sale, importing, Developing or Commercializing any Licensed Compounds or Products, or holding Selecta or any such other entities liable for damages for any such activities, in each case such holding unappealable or unappealed within the time allowed for appeal, or (ii) a settlement of any action or proceeding requiring payment of damages by Selecta or any such party, and (b) such action or proceeding relates to a breach of 3SBio’s representations, warranties or covenants under this Agreement or any Supply Agreement, Selecta will be entitled to reduce royalties payable to 3SBio hereunder by up to [***] percent ([***]%) in each subsequent Calendar Quarter until such time as Selecta recovers in full such [***] percent ([***]%) of all such damages and expenses.

9.4 Patent Extensions; Orange Book Listings; Patent Certifications.

(a) Patent Term Extension. If elections with respect to obtaining patent term extension or supplemental protection certificates or their equivalents in any country with respect to 3SBio Patent Rights or other Patents covering Products or their manufacture or use are available, Selecta will have the sole right to make any such elections.

(b) Data Exclusivity and Orange Book Listings. With respect to data exclusivity periods (such as those periods listed in the Orange Book (including any available pediatric extensions) or periods under national implementations of Article 10.1(a)(iii) of Directive 2001/EC/83, and all equivalents in any country), Selecta will have the sole right to seek and maintain all such data exclusivity periods available for the Products. Selecta has the sole right to control which 3SBio Patent Rights, if any, will be listed in the U.S. FDA Orange Book or any similar patent listing in any other country with respect to Products. 3SBio will cooperate with Selecta’s efforts taken under this Section 9.4(b).

(c) Notification of Patent Certification. 3SBio will notify and provide Selecta with copies of any allegations of alleged patent invalidity, unenforceability or non-infringement of a 3SBio Patent Right pursuant to a Paragraph IV Patent Certification by a Third Party filing an Abbreviated New Drug Application or an application under §505(b)(2) of the United States Food, Drug, and Cosmetic Act (as amended or any replacement thereof), or any other U.S. application filed with the FDA for Regulatory Approval of a Generic Product, or any foreign equivalent thereof. Such notification and

copies will be provided to Selecta within two (2) days after 3SBio receives such certification, and will be sent to the address set forth in Section 13.5.

(d)3SBio Cooperation. With respect to all of the rights and activities identified in this Section 9.4, 3SBio will cooperate with Selecta in the exercise of its authority granted herein, and will execute such documents and take such additional action as Selecta may request in connection therewith.

Section 10.Confidential Information and Publicity.

10.1 Confidentiality.

(a)Confidential Information. Except as expressly provided herein, each of the Parties agrees that, for itself and its Affiliates, and for as long as this Agreement is in effect and for a period of [***] years thereafter (provided, that with respect to each disclosure of Confidential Information that is a trade secret, the obligations created herein will survive until such time that it can be demonstrated that the trade secret has become publicly available in the public domain), a Party and its Affiliates (the “Receiving Party”) receiving Confidential Information of the other Party or its Affiliates (the “Disclosing Party”) will (i) not disclose such Confidential Information to any Third Party without the prior written consent of the Disclosing Party, except for disclosures expressly permitted below, and (ii) not use such Confidential Information for any purpose except those licensed or otherwise authorized or permitted by this Agreement. For clarity, all Confidential Information of Selecta and its Affiliates received by or disclosed to 3SBio hereunder will be used by 3SBio only for ensuring that Selecta and its Affiliates comply with their obligations hereunder and for no other purposes.

(c) Review. In the event either Party (the “Issuing Party”) desires to issue any publicity, new release or other public announcement relating to this Agreement or the transactions contemplated hereby or the terms hereof, the Issuing Party will provide the other Party (the “Reviewing Party”) with a copy of the proposed release, announcement or statement (the “Release”). The Issuing Party will specify with each such Release, taking into account the urgency of the matter being disclosed, a reasonable period of time within which the Reviewing Party may provide any comments on such Release and if the Receiving Party fails to provide any comments during the response period called for by the Issuing Party, the Reviewing Party will be deemed to have consented to the issuance of such Release; provided, however, that as it relates to the disclosure of the results of any clinical trial conducted by Selecta or any health or safety matter related to a Product, 3SBio acknowledges that announcements may need to be made on extremely short notice, and although Selecta will endeavor to provide 3SBio adequate time for such a review, Selecta will be free to make necessary public disclosures as promptly as it deems necessary and appropriate. If the Reviewing Party provides any comments, the Parties will consult on such Release and work in good faith to prepare a mutually acceptable Release. Either Party may subsequently publicly disclose any information previously contained in any Release so consented to. Notwithstanding the foregoing, nothing herein will limit or impair a Party’s ability to disclose any information required to be disclosed by the laws of the U.S. Securities and Exchange Commission or by the rules and regulations any applicable securities exchange or by any other Regulatory Authority; provided, however that the disclosing Party will use reasonable efforts to limit such disclosure to the extent permitted.

10.3 Relationship to the Confidentiality Agreement. This Agreement supersedes the Confidentiality Agreement, provided that all “Confidential Information” disclosed or received by the Parties thereunder will be deemed “Confidential Information” hereunder and will be subject to the terms and conditions of this Agreement.

10.4 Remedies. Each Party will be entitled to seek, in addition to any other right or remedy it may have, at law or in equity, a temporary injunction, without the posting of any bond or other security, enjoining or restraining the other Party from any violation or threatened violation of this Section 10.

EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN THIS AGREEMENT, THE PARTIES MAKE NO REPRESENTATIONS AND EXTEND NO WARRANTY OF ANY KIND (AND EACH PARTY HEREBY EXPRESSLY DISCLAIMS ANY AND ALL REPRESENTATIONS AND WARRANTIES NOT EXPRESSLY PROVIDED IN THIS AGREEMENT), EITHER EXPRESS OR IMPLIED, INCLUDING WITH RESPECT TO ANY LICENSED COMPOUNDS, PRODUCTS, PATENT RIGHTS OR KNOW-HOW, INCLUDING WARRANTIES OF VALIDITY OR ENFORCEABILITY OF ANY PATENT RIGHTS, TITLE, QUALITY, MERCHANTABILITY, FITNESS FOR A PARTICULAR USE OR PURPOSE, PERFORMANCE, AND NONINFRINGEMENT OF ANY THIRD PARTY PATENTS OR OTHER INTELLECTUAL PROPERTY RIGHTS. For clarity, this Section 11.3 will not apply to the Supply Agreements.

11.4 Limitation of Liability. NOTWITHSTANDING ANYTHING IN THIS AGREEMENT OR OTHERWISE, NEITHER PARTY WILL BE LIABLE TO THE OTHER OR ANY THIRD PARTY WITH RESPECT TO ANY SUBJECT MATTER OF THIS AGREEMENT FOR ANY INDIRECT, SPECIAL OR CONSEQUENTIAL DAMAGES; PROVIDED, HOWEVER, THAT THIS SECTION 11.4 WILL NOT APPLY TO THE PARTIES’ INDEMNIFICATION RIGHTS AND OBLIGATIONS UNDER SECTIONS 11.6(a) AND 11.6(b) OR ANY BREACH BY A PARTY OF SECTION 2.3, Section 10 OR SECTION 11.1. For clarity, this Section 11.4 will not apply to the Supply Agreements.

11.5 Performance by Affiliates. The Parties recognize that each Party may perform some or all of its obligations under this Agreement through Affiliates; provided, however, that each Party will remain responsible and liable for the performance by its Affiliates and will cause its Affiliates to comply with the provisions of this Agreement in connection therewith.

11.6 Indemnification.

(a) Selecta Indemnity. Selecta hereby agrees to indemnify and hold 3SBio and its Affiliates, and their respective employees, directors, agents and consultants, and their respective successors, heirs and assigns and representatives (“3SBio Indemnitees”) harmless from and against all claims, liability, threatened claims, damages, expenses (including reasonable attorneys’ fees), suits, proceedings, losses or judgments, whether for money or equitable relief, of any kind, including but not limited to death, personal injury, illness, product liability or property damage or the failure to comply with applicable law or regulation (collectively, “Losses”), arising from any Third Party claim due to (i) the research, Development, Commercialization (including promotion, advertising, offering for sale, sale or other disposition), transfer, importation or exportation, Manufacture, labeling, handling or storage, or use of, or exposure to, the Licensed Compounds or any Product by or for Selecta or any of its Affiliates, Sublicensees, agents and consultants or (ii) Selecta’s (or its Affiliates’ and Sublicensees’) use or practice of 3SBio Patent Rights and 3SBio Know-How or (iii) arising from any material breach of any obligation, representation or warranty of Selecta hereunder, except, in each case, to the extent that such Losses arise from (A) infringement or misappropriation of patent or other intellectual property rights or know-how by any 3SBio Indemnitees, (B) the gross negligence, recklessness or willful misconduct of any 3SBio Indemnitees, or (C) any material breach of any obligation, representation or warranty of 3SBio hereunder.

(b) 3SBio Indemnity. 3SBio hereby agrees to indemnify and hold Selecta, its Affiliates and Sublicensees, and their respective employees, directors, agents and consultants, and their respective successors, heirs and assigns and representatives (“Selecta Indemnitees”) harmless from and against all Losses arising from any Third Party claim due to (i) the research, Development, transfer, importation or exportation, Manufacture, labeling, handling or storage, or use of, or exposure to, the Licensed Compounds or any Product by or for 3SBio or any of its Affiliates, sublicensees, agents and contractors or (ii) 3SBio’s (or its Affiliates’ and sublicensees’) use and practice otherwise of 3SBio Patent Rights and Selecta Confidential Information or (iii) arising from any material breach of any obligation, representation or warranty of Selecta hereunder, except, in each case, to the extent that such Losses arise from (A) infringement or misappropriation of patent or other intellectual property rights or know-how by any Selecta Indemnitees, (B) the gross negligence, recklessness or willful misconduct of any Selecta Indemnitees, or (C) any material breach of any obligation, representation or warranty of Selecta hereunder.

(c) Indemnification Procedure. A claim to which indemnification applies under Section 11.6(a) or Section 11.6(b) will be referred to herein as a “Claim”. If any person or entity (each, an “Indemnitee”) intends to claim indemnification under this Section 11.6, the Indemnitee will notify the other Party (the “Indemnitor”) in writing promptly upon becoming aware of any claim that may be a Claim (it being understood and agreed, however, that the failure by an Indemnitee to give such notice will not relieve the Indemnitor of its indemnification obligation under this Agreement except and only to the extent that the Indemnitor is actually prejudiced as a result of such failure to give notice). The Indemnitor will have the right to assume and control the defense of such Claim at its own expense with counsel selected by the Indemnitor and reasonably acceptable to the Indemnitee; provided, however, that an Indemnitee will have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnitee, if representation of such Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential differing interests between such Indemnitee and any other party represented by such counsel in such proceedings. If the Indemnitor does not assume the defense of such Claim as aforesaid, the Indemnitee may defend such Claim but will have no obligation to do so. The Indemnitee will not settle or compromise any Claim without the prior written consent of the Indemnitor, and the Indemnitor will not settle or compromise any Claim in any manner which would have an adverse effect on the Indemnitee’s interests, without the prior written consent of the

Indemnitee, which consent, in each case, will not be unreasonably withheld. The Indemnitee will reasonably cooperate with the Indemnitor at the Indemnitor’s expense and will make available to the Indemnitor all pertinent information under the control of the Indemnitee, which information will be subject to Section 10.

11.7 Insurance. Each Party agrees to maintain during the term of this Agreement such insurance coverage as [***], taking into to consideration the activities and other circumstances of such Party.

Section 12.Term, Termination and Survival.

12.1 Term. The term of this Agreement, together with the term of the Original Agreement, commenced as of the Original Effective Date and, unless sooner terminated in accordance with the terms hereof, will continue in effect until the expiration of Selecta’s royalty obligations to 3SBio under Section 8.3 in all countries in the Territory (the “Term”). However, effective upon the expiration of Selecta’s royalty obligations to 3SBio with respect to a given Product in a given country in the Territory: (a) the licenses granted to Selecta in Section 2.1 under the 3SBio Patent Rights and 3SBio Know-How will become fully paid up, perpetual, irrevocable and royalty-free with respect to such Product in such country; and (b) Selecta and its Affiliates and Sublicensees will have the right to continue to Develop and Commercialize the relevant Product in such country without further obligation to 3SBio.

12.2 Termination for Material Default. Either Party will have the right to terminate this Agreement upon delivery of written notice to the other Party in the event of any default in the performance by such other Party of any of such other Party’s material obligations under this Agreement, provided that such default has not been cured within ninety (90) days, or, in the event such default results in a failure to make payment when due hereunder, thirty (30) days, after written notice thereof is given by the non-defaulting Party to the defaulting Party specifying the nature of the alleged default, provided the Parties will take all reasonable steps to resolve the matter pursuant to the process set forth in Section 13.6(a) during the applicable cure period and before any such termination becomes effective. Termination of this Agreement by 3SBio under this Section 12.2 will be on a country-by-country and product-by-product basis (and not for the Agreement as a whole) if the default giving rise to termination is reasonably specific to one or more countries or one or more products (e.g., a royalty dispute for one product in one or more countries) and does not have any material impact on the obligations of the Selecta under this Agreement. For clarity, the termination rights and related cure periods do not apply to the Supply Agreements.

12.3 Termination for Convenience by Selecta. Selecta may terminate this Agreement in full for any reason effective upon sixty (60) days prior written notice to 3SBio; provided, however, that Selecta will have the right to terminate this Agreement with respect to a given Product with immediate effect upon written notice to 3SBio in the event that Selecta or any of its Affiliates or Sublicensees identifies a safety or efficacy concern with respect to such Product. Termination of this Agreement by Selecta under this Section 12.3 may be on a country-by-country or product-by-product basis.

12.4 Bankruptcy.

(a)Termination. Each Party will have the unilateral right to terminate this Agreement at any time during its Term by providing written notice with immediate effect in the event that: (i) the other Party files in any court or agency pursuant to any statute or regulation of any state,

country or jurisdiction, a petition in bankruptcy or insolvency or for reorganization or for a similar arrangement or for the appointment of a receiver or trustee of that Party or of its assets, or (ii) if the other Party proposes a written agreement of composition or extension of its debts generally, or (iii) if the other Party is served with an involuntary petition against it, filed in any insolvency proceeding, and such petition is not dismissed within sixty (60) days after the filing thereof, or (iv) if the other Party proposes or is a party to any dissolution or liquidation, or (v) if the other Party makes an assignment for the benefit of its creditors.

(b)Consequences of Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by 3SBio or their Affiliates are, and will otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of right to “intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code. The Parties agree that Selecta (and its Affiliates and Sublicensees) as licensees of such rights under this Agreement, will retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code and any foreign counterparts thereto. For clarity, the provisions of this Section 12.4(b) will be without prejudice to any rights the terminating Party may have arising under any applicable insolvency statute or other applicable law.

12.5 Effect of Certain Terminations.

(a) Upon termination of this Agreement by 3SBio pursuant to Section 12.2 or by Selecta pursuant to Section 12.3, or with respect to each applicable product and country as to which termination occurs pursuant to Section 12.2 (the rights and obligations of the Parties as to the remaining products and countries in which termination under Section 12.2 has not occurred, being unaffected by such termination), all rights and licenses granted to Selecta in Section 2.1 will terminate with respect to each such terminated product and country, and Section 2.2(a) will apply to all Sublicensees in each such terminated country for each such terminated product. In addition, upon the written request of 3SBio, Selecta will grant to 3SBio a right to access and reference all Regulatory Approvals and Regulatory Filings owned by Selecta or its Affiliates concerning each such terminated product in the terminated country.

(b) In the event of a termination by Selecta under Section 12.2 (3SBio breach):

(i)As of the effective date of such termination, (A) the 3SBio Distribution Option will terminate, and (B) 3SBio will, within thirty (30) days after the effective date of such termination, return to Selecta all of Selecta’s Confidential Information that is in 3SBio’s (or its Affiliates’) possession or control, provided that 3SBio may keep one copy of Selecta’s Confidential Information in its confidential legal files for purposes of confirming compliance with this Agreement.

(ii)As of the effective date of such termination, the licenses granted to Selecta by 3SBio pursuant to Section 2.1 will become perpetual, irrevocable licenses.

(iii)Selecta may exercise its co-exclusive rights under Section 2.1(b) and 3SBio will promptly assign any manufacturing or supply agreements relating to the Licensed Compounds or Licensed Products in the Territory to Selecta or its designee;

(iv)Selecta will continue to be obligated to pay the milestone and royalty amounts under Sections 8.2 and 8.3 that would otherwise have been payable under the terms of this Agreement during its Term; provided, however, that such amounts will be reduced by [***] percent

([***]%) of the amounts that would otherwise have been payable under the terms of this Agreement during its term.

12.6 Right to Sell-Off Inventory. Upon termination of this Agreement for any reason, should Selecta or any of its Affiliates or Sublicensees have any inventory of any Product, each of them will have [***] months thereafter in which to dispose of such inventory (subject to the payment to 3SBio of any royalties due hereunder thereon).

12.7 Survival. In addition to the termination consequences set forth in Section 12.5, the following provisions will survive expiration or termination of this Agreement for any reason, as well as any other provision which by its terms or by the context thereof, is intended to survive such termination: Sections 10.1, 10.3, 10.4, 11.3, 11.4, 12.6, 13.5-13.8, and 13.10. Expiration or termination of this Agreement for any reason will not relieve the Parties of any liability or obligation which accrued hereunder prior to the effective date of such termination or expiration, nor preclude either Party from pursuing all rights and remedies it may have hereunder or at law or in equity, subject to Section 13.6, with respect to any breach of this Agreement nor prejudice either Party’s right to obtain performance of any obligation.

Section 13.General Provisions.

13.1 Assignment. Neither Party may assign this Agreement, delegate its obligations or otherwise transfer licenses or other rights created by this Agreement, except as otherwise expressly permitted hereunder or without the prior written consent of the other Party, which consent will not be unreasonably withheld, conditioned or delayed; provided, that each Party may assign this Agreement as a whole without such consent to an Affiliate or in connection with the acquisition of such Party, provided that such Party provides written notice to the other Party of such acquisition. For clarity, the meaning of “acquisition” includes, without limitation any disposal or transfer in any manner whatsoever effected whether for consideration or without a consideration including but not limited to any sale, contribution in kind, statutory merger or de-merger, donation, exchange, transfer or rent of the business as a going-concern, or other transfer whatsoever and whether in whole or in part. In addition, it will be reasonable for a Party to not to give its consent to the assigning Party under this Section 13.1 if, among other things, the assignee or delegate, does not have adequate financial or technical resources to comply with the assigning Party’s obligations hereunder, or would affect the continuity of supply of any Licensed Compound or Licensed Product under the Supply Agreements. Any assignment or transfer in violation of this Section 13.1 will be void. This Agreement will inure to the benefit of, and be binding upon, the legal representatives, successors and permitted assigns of the Parties. For clarity, any assignment under this Section 13.1 will be treated as a novation, and the counterparty will sign such documents as required to affect such novation. For this purpose, references to a Party’s rights under this Agreement include any similar rights to which another person becomes entitled as a result of a novation of this Agreement.

13.2 Force Majeure. Neither Party will be held liable or responsible to the other Party nor be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement if, but only to the extent that, such failure or delay results from causes beyond the reasonable control of the affected Party, potentially including fire, floods, embargoes, terrorism, war, acts of war (whether war be declared or not), insurrections, riots, civil commotions, strikes, lockouts or other labor disturbances, acts of God or acts, omissions or delays in acting by any Governmental Authority or any other Party; provided that the Party affected will promptly notify the

other of the force majeure condition and will exert reasonable efforts to eliminate, cure or overcome any such causes and to resume performance of its obligations as soon as possible.

13.3 Severability. If any one or more of the provisions contained in this Agreement is held for any reason to be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein will not in any way be affected or impaired thereby, but this Agreement will be construed as if such invalid, illegal or unenforceable provision or provisions had never been contained herein unless the deletion of such provision or provisions would result in such a material change as to cause completion of the transactions contemplated herein to be impossible or significantly frustrated and provided that the performance required by this Agreement with such clause deleted remains substantially consistent with the intent of the Parties; provided that in the event that a Third Party reasonably asserts that patent misuse has occurred based on any aspect of this Agreement, the Parties will negotiate in good faith to make any necessary amendments to this Agreement to preserve the validity and enforceability of the applicable Patents and make as few revisions as possible to maintain the original intent of the Parties under this Agreement.

13.4 Amendment; Waiver. This Agreement may not be modified, amended or rescinded, in whole or part, except by a written instrument signed by the Parties; provided that any unilateral undertaking or waiver made by one Party in favor of the other will be enforceable if undertaken in a writing signed by the Party to be charged with the undertaking or waiver. No delay or omission by either Party hereto in exercising any right or power occurring upon any noncompliance or default by the other Party with respect to any of the terms of this Agreement will impair any such right or power or be construed to be a waiver thereof. A waiver by either of the Parties of any of the covenants, conditions or agreements to be performed by the other will not be construed to be a waiver of any succeeding breach thereof or of any other covenant, condition or agreement herein contained.

13.5 Notices. Except as otherwise provided herein, all notices under this Agreement will be sent by certified mail or by overnight courier service, postage prepaid, to the following addresses of the respective Parties:

If to Selecta, to: Selecta Biosciences, Inc.

13.6 Dispute Resolution. Disputes arising under or in connection with this Agreement will be resolved pursuant to this Section 13.6; provided, however, that in the event a dispute cannot be resolved without an adjudication of the rights or obligations of a Third Party (other than a 3SBio Indemnitee or

Selecta Indemnitee identified in Sections 11.6(a) or 11.6(b)11.6(a), as applicable), the dispute procedures set forth in this Section 13.6 will be inapplicable as to such dispute.

(a)In the event of a dispute between the Parties, the Parties will first attempt in good faith to resolve such dispute by negotiation and consultation between themselves.

(b)In the event the Parties are not able to resolve such dispute, either Party may at any time after such [***] day period submit such dispute to be finally settled by arbitration administered in accordance with the Arbitration Rules of the International Chamber of Commerce (“ICC”) in effect at the time of submission. The arbitration will be heard and determined by one (1) arbitrator. Selecta and 3SBio will agree on the arbitrator, or, failing agreement within [***] days following the date of receipt by the respondent of the claim, by the ICC. Such arbitration will take place in New York, New York. The arbitrator so appointed will decide in accordance with the rules of the ICC and will render the award within the term established by such rules, unless extended by the parties. The language of arbitration will be English. The arbitration award so given will be a final and binding determination of the dispute, will be fully enforceable in any court of competent jurisdiction, and will not include any damages expressly prohibited by Section 11.4.

(c)Costs of arbitration are to be divided as follows: the losing Party will pay [***] percent ([***]%) of the costs and fees of the winning Party. Except in a proceeding to enforce the results of the arbitration or as otherwise required by law, neither Party nor the arbitrator may disclose the existence, content or results of any arbitration hereunder without the prior written consent of both Parties.

(d)Notwithstanding the dispute resolution procedures set forth in this Section 13.6, in the event of an actual or threatened breach hereunder, the aggrieved Party may seek equitable relief (including restraining orders, specific performance or other injunctive relief) in any court or other forum, without first submitting to any dispute resolution procedures hereunder.

(e)The Parties agree that all applicable statutes of limitation and time-based defenses (such as estoppel and laches) will be tolled while the dispute resolution procedures set forth in this Section 13.6 are pending, and the Parties will cooperate in taking all actions reasonably necessary to achieve such a result. In addition, during the pendency of any dispute under this Agreement initiated before the end of any applicable cure period under Section 12.2, (i) this Agreement will remain in full force and effect, (ii) the provisions of this Agreement relating to termination for material breach will not be effective, (iii) the time periods for cure under Section 12.2 as to any termination notice given prior to the initiation of the arbitration proceeding will be tolled, and (iv) neither Party will issue a notice of termination pursuant to this Agreement based on the subject matter of the arbitration proceeding (and no effect will be given to previously issued termination notices), until the court has confirmed the existence of the facts claimed by a Party to be the basis for the asserted material breach.

13.7 Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York, without regard to its conflicts of law provisions; provided that any dispute relating to the scope, validity, enforceability or infringement of any patents or know-how will be governed by, and construed and enforced in accordance with, the substantive laws of the jurisdiction in which such patents or know-how apply.

13.8 Further Assurances. Each Party agrees to do and perform all such further acts and things and will execute and deliver such other agreements, certificates, instruments and documents

necessary or that the other Party may deem advisable in order to carry out the intent and accomplish the purposes of this Agreement and to evidence, perfect or otherwise confirm its rights hereunder.

13.9 Relationship of the Parties. Each Party is an independent contractor under this Agreement. Nothing contained herein is intended or is to be construed so as to constitute 3SBio and Selecta as partners, agents or joint venturers. Neither Party will have any express or implied right or authority to assume or create any obligations on behalf of or in the name of the other Party or to bind the other Party to any contract, agreement or undertaking with any Third Party. There are no express or implied third party beneficiaries hereunder (except for Selecta Indemnitees other than Selecta and 3SBio Indemnitees other than 3SBio for purposes of Section 11.6).

13.10 Entire Agreement. This Agreement (along with the Exhibits) contains the entire understanding of the Parties with respect to the subject matter hereof and supersedes and replaces any and all previous arrangements and understandings, including the Original Agreement and the Confidentiality Agreement, whether oral or written, between the Parties with respect to the subject matter hereof. The foregoing shall not be interpreted as a waiver of any remedies available to either Party as a result of any breach prior to the Effective Date by the other Party of the Original Agreement.

13.11 Headings. The captions to the several Sections hereof are not a part of this Agreement, but are merely guides or labels to assist in locating and reading the several Sections hereof.

13.12 Waiver of Rule of Construction. Each Party has had the opportunity to consult with counsel in connection with the review, drafting and negotiation of this Agreement. Accordingly, the rule of construction that any ambiguity in this Agreement will be construed against the drafting party will not apply.

13.13 Interpretation. Whenever any provision of this Agreement uses the term “including” (or “includes”), such term will be deemed to mean “including without limitation” (or “includes without limitations”). “Herein,” “hereby,” “hereunder,” “hereof” and other equivalent words refer to this Agreement as an entirety and not solely to the particular portion of this Agreement in which any such word is used. The term “or” will mean “and/or” hereunder. All definitions set forth herein will be deemed applicable whether the words defined are used herein in the singular or the plural. References to “months” hereunder refer to calendar months. Unless otherwise provided, all references to Sections, Schedules and Exhibits in this Agreement are to Sections, Schedules and Exhibits of this Agreement. References to any Sections include Sections and subsections that are part of the related Section (e.g., a section numbered “Section 2.1” would be part of “Section 2”, and references to “Section 2.1”or “Section 2” would also refer to material contained in the subsection described as “Section 2.1(a)”).

13.14 Counterparts; Facsimiles. This Agreement may be executed in one or more counterparts, each of which will be deemed an original and all of which together will constitute one and the same instrument. Facsimile or PDF execution and delivery of this Agreement by either Party followed by exchange of original signatures will constitute a legal, valid and binding execution and delivery of this Agreement by such Party.

IN WITNESS WHEREOF, the Parties have caused this Development and License Agreement to be executed by their respective duly authorized officers as of the Effective Date.
