Paragon shall consider and discuss in good faith any additional requests for assistance made by Apogee, which assistance may be provided upon mutual agreement of the Parties.

2.5

Paragon Rights with Respect to Multispecific Antibodies.

(a)

Subject to the terms of this Agreement, including Section 2.5(b) below and Section 2.6, Paragon reserves and retains the non-exclusive right under the Licensed Antibody Technology to Develop, Manufacture, Commercialize and otherwise exploit Multispecific Antibodies and Multispecific Products in the

Field in the Territory. If Paragon exercises such right, then Paragon shall pay royalties to Apogee in accordance with Article IV, mutatis mutandis, with respect to any Multispecific Antibodies and Multispecific Products that are Commercialized by Paragon or its Affiliates or sublicensees (other than Apogee and its Affiliates and Sublicensees) in the Field in the Territory, provided, that the reference to Apogee Antibody Patents in clause (b) of the Royalty Term definition shall be disregarded.

(b)

Apogee has designated [***] Licensed Antibody or Derived Antibody, as set forth on Exhibit C, as its lead compound, and shall have the right to designate [***] Licensed Antibody or Derived Antibody as its backup compound by providing written notice thereof to Paragon within [***] of the Effective Date (each such designated Licensed Antibody or Derived Antibody, a “Designated Multispecific Antibody”). From and after receipt of Apogee’s notice, the license grant to Apogee under Section 2.1(b) shall be exclusive with respect to the Designated Multispecific Antibodies and Paragon’s rights under Section 2.5(a) shall expressly exclude the right to Develop, Manufacture, Commercialize or otherwise exploit (i) Multispecific Antibodies that have identical sequence identity within their CDRs as a Designated Multispecific Antibody, or (ii) Multispecific Products that comprise or contain any Multispecific Antibody referenced in clause (i). For the avoidance of doubt, if Paragon engages in Development or Manufacture of a Multispecific Antibody that meets the criteria of clause (i) or (ii) above before Apogee designates such Multispecific Antibody as a Designated Multispecific Antibody, then Paragon shall not be in breach of this Agreement, provided that, Paragon ceases all such Development or Manufacture within [***] days following receipt of Apogee’s written notice of designation.

2.6

Right of First Negotiation.

(a)

Commencing on the Effective Date and continuing until the [***] anniversary thereof (the “ROFN Period”), Paragon will promptly notify Apogee in writing if (i) Paragon or any of its Affiliates have developed a descriptive research plan with respect to the Development of a ROFN Multispecific Antibody similar in breadth and detail to the TSLP Research Plan by and between the Parties, executed on [***] or a bona fide plan to license or grant rights in a ROFN Multispecific Antibody to a Third Party, or (ii) Paragon or any of its Affiliates enters into good faith negotiations pursuant to an offer to or from any Third Party relating to the foregoing. Together with such notice, Paragon will provide to Apogee all material information and research plans developed by Paragon with respect to such ROFN Multispecific Antibody, including existing drafts of any proposed filings to any patent office prepared by or on behalf of Paragon, or copies of any actual filings to any patent office made by or behalf of Paragon, in each case with respect to Multispecific Patents that Cover such ROFN Multispecific Antibody. Apogee will have [***] days from receipt of Paragon’s notice to deliver a written notice to Paragon of Apogee’s desire to engage in negotiations for an agreement concerning the Development of or grant of a license or other rights to such ROFN Multispecific Antibody, provided, that, if within such [***] day period Apogee reasonably requests additional information relating to the research plan for the ROFN Multispecific Antibody (“Additional Information”), then Paragon shall use reasonable efforts to provide such Additional Information and the notice period shall be automatically extended beyond the initial [***] day period by such number of days necessary to provide Apogee [***] days to review such Additional Information following its receipt. Paragon’s obligation to provide any Additional Information shall be limited to data and information that is reasonably available to Paragon and in the form in which it is currently maintained by Paragon, and in no event shall Paragon be required to perform any research activities or generate new reports or documentation to comply with any request for Additional Information.

(b)

If Apogee does not provide such written notice to Paragon of its interest to engage in such negotiations within such [***] day period, as may be extended as set forth in Section 2.6(a), then Paragon shall be free to enter into an agreement with a Third Party with respect to the Development of or grant of a license or

other rights to such ROFN Multispecific Antibody and corresponding products comprising or containing such ROFN Multispecific Antibody (“ROFN Multispecific Product”) without further obligation to Apogee under this Section 2.6.

(c)

If Apogee does provide Paragon such written notice within such [***] day period, the Parties will negotiate [***] on a non-exclusive basis for a period of up to [***] months from the date of Apogee’s notice (“ROFN Negotiation Period”), an agreement with respect to the Development of or grant of a license or other rights to such ROFN Multispecific Antibody and corresponding ROFN Multispecific Products. Prior to and during the ROFN Negotiation Period, neither Paragon nor its Affiliates shall enter into an agreement with respect to any such ROFN Multispecific Antibody or any corresponding ROFN Multispecific Products with any Third Party that would restrict Paragon or its Affiliate from entering into an agreement with Apogee with respect to the Development of or grant of a license or other rights to such ROFN Multispecific Antibody and corresponding ROFN Multispecific Products. For clarity, prior to and during the ROFN Negotiation Period, Paragon shall have the right to enter into agreements with Third Party service providers providing services to Paragon or its Affiliates with respect to such ROFN Multispecific Antibody and ROFN Multispecific Products. In the event that the Parties have not entered into an agreement with respect to such ROFN Multispecific Antibody and corresponding ROFN Multispecific Products prior to the expiration of the ROFN Negotiation Period, then Paragon and its Affiliates shall be free to enter into an agreement with a Third Party with respect to the Development of or grant of a license or other rights to such ROFN Multispecific Antibody and corresponding ROFN Multispecific Products without further obligation to Apogee under this Section 2.6. If (i) the Parties enter into a license or another agreement with a grant of such rights to Apogee with respect to a ROFN Multispecific Antibody as described in subsection (b) of such definition, and (ii) Apogee had not previously requested Paragon to deliver to [***] a [***] Election Notice pursuant to Section 3.2 of the [***] Agreement with respect to the applicable [***] Project Antibody(ies) included in such ROFN Multispecific Antibody prior to the expiration of the Apogee Election Period, then the terms of such agreement by and between the Parties shall include the obligation for Apogee to reimburse Paragon for all payments made to [***] by Paragon under the [***] Agreement following the expiration of the Apogee Election Period.

2.7

Third Party In-Licenses.

(a)

Paragon shall notify Apogee in writing about any plan to enter into any exclusive in-license agreement with a Third Party for Patents that are (i) solely and exclusively related to the Licensed Antibodies, and (ii) are necessary to Develop, Manufacture, Commercialize or otherwise exploit the Licensed Antibodies, and following Apogee’s receipt of such notice the Parties shall discuss whether and to what extent both Parties are interested in acquiring such a license or such rights. Apogee shall have [***] days to notify Paragon whether it intends to obtain a license or rights to such Patents for the Development, Manufacture, Commercialization or other exploitation of the Apogee Products. If Apogee (x) notifies Paragon that it declines to obtain a license or rights in such Patents, (y) does not provide any notice to Paragon during such [***] day notice period, or (z) fails to obtain a license or rights in such Patents within [***] days following notice to Paragon that it intends to obtain such license or rights, then Paragon may enter into such in-license agreement (each such in-license agreement, a “Paragon Exclusive Third Party Agreement”), and shall use reasonable efforts to obtain commercially reasonable terms under each such Paragon Exclusive Third Party Agreement.

(b)

Apogee acknowledges and agrees that Paragon may enter into in-license agreements with Third Parties after the Effective Date (other than Paragon Exclusive Third Party Agreements) for Patents that, if Controlled by Paragon or its Affiliates, would constitute Licensed Antibody Patents or Other Licensed Patents (such additional in-license agreements, together with the Paragon Exclusive Third Party Agreements, the

“Paragon Third Party Agreements”). Paragon will provide to Apogee a copy of each Paragon Third Party Agreement following execution thereof, subject to applicable confidentiality obligations and reasonable redaction of provisions that do not relate to the potential use of the applicable in-licensed Patents under this Agreement. The Parties will discuss in good faith how the costs under each Paragon Third Party Agreement would be reasonably allocated to Apogee. The Patents licensed to Paragon under a Paragon Third Party Agreement shall only be included within the Licensed Antibody Patents or the Other Licensed Patents licensed to Apogee under Section 2.1 from and after such time when Apogee agrees in writing to (i) reimburse Paragon for royalties and other consideration due under such Paragon Third Party Agreement that are allocable to the Development, Manufacture, Commercialization or other exploitation of an Apogee Product in the Territory in connection with a grant to Apogee of a sublicense under such Patents (the “Reimbursement Obligation”), and (ii) comply with the terms of such Paragon Third Party Agreement to the extent those terms have been previously disclosed to Apogee, are applicable to Apogee as a sublicensee and relevant to the licenses and rights granted by Paragon to Apogee under this Agreement (provided, that in the event of any conflict between the terms of this Agreement and the terms of such Paragon Third Party Agreement that are applicable to Apogee as a sublicensee thereof, the terms of such Paragon Third Party Agreement shall control to the extent necessary to maintain compliance with the terms of such Paragon Third Party Agreement, and Apogee shall not be deemed to be in breach of this Agreement to the extent that it is complying with a term of such Paragon Third Party Agreement applicable to Apogee that conflicts with a term of this Agreement). Notwithstanding the foregoing, upon the occurrence of the [***] License Effective Date, Apogee has agreed to receive a sublicense under the [***] IP in accordance with Section 2.1(d) and subject to the terms of Section 2.9. Apogee shall comply with the Reimbursement Obligation by paying to Paragon any amounts subject to the Reimbursement Obligation at least [***] Business Days prior to the date when such amounts are payable by Paragon to the counterparty licensor under the applicable Paragon Third Party Agreement.

2.8

Right of First Refusal under the [***] Agreement. If, following the [***] License Effective Date, Paragon receives written notice from [***] in accordance with Section 3.5 of the [***] Agreement with respect to the “Additional Antibodies ROFR” (as defined in the [***] Agreement), then Paragon will promptly (within [***] Business Days) provide Apogee with a copy of such written notice and the associated “Additional Antibody Third Party Terms” (as defined in the [***] Agreement) received from [***]. During the “Additional Antibodies ROFR Period” (as defined in the [***] Agreement), Paragon shall promptly assist Apogee in obtaining from [***] any information reasonably requested by Apogee to enable Apogee to determine whether to exercise such Additional Antibodies ROFR. Apogee may exercise such Additional Antibodies ROFR by providing written notice thereof to Paragon at least [***] Business Days prior to the expiration of the Additional Antibodies ROFR Period, and Paragon shall exercise the Additional Antibodies ROFR on behalf of Apogee within the Additional Antibodies ROFR Period. If Apogee exercises such Additional Antibodies ROFR, Paragon, acting on behalf of Apogee, and [***] shall promptly enter into an agreement on the Additional Antibody Third Party Terms and the Parties shall negotiate in good faith any necessary amendments to this Agreement, it being understood and agreed that Apogee shall be responsible for any amounts payable to [***] in respect thereof. For clarity, Apogee shall have no rights under this Section 2.8 if Apogee does not request Paragon to deliver to [***] a [***] Election Notice pursuant to Section 3.2 of the [***] Agreement prior to the expiration of the Apogee Election Period.

If any Apogee Product contains a combination of (a) one (1) or more Licensed Antibodies or Derived Antibodies, and (b) one (1) or more Antibodies owned or controlled by Paragon or any of its Affiliates, the rights to such Antibody(ies) which are licensed or assigned to Apogee or any of its Affiliates under a separate agreement, then such Apogee Product shall be treated as a Combination Product under this Agreement and each other separate agreement; provided, however, that Paragon shall not receive more than a [***] percent ([***]%) total royalty on the Net

Sales of such Apogee Product. For clarity, any Net Sales of an Apogee Product made in a given country after the expiration of the Royalty Term for such Apogee Product in such country will not be royalty-bearing.

(b)

If, during any Calendar Quarter during the Royalty Term with respect to a particular Apogee Product in a particular country, there is no Valid Claim of a Licensed Antibody Patent Covering such Apogee Product in such country, then the royalty rate for the Royalty Payments set forth in Section 4.2(a) for such Calendar Quarter shall be reduced to [***] percent ([***]%).

4.3

Payment Reports. Within [***] days after the end of the [***], Apogee shall provide to Paragon a written report, on an [***] basis, stating [***], [***]; and [***]. All Royalty Payments described in such written report shall be made by Apogee at the same time it submits such written report to Paragon.

4.4

Payment Method. All payments due under this Agreement to Paragon shall be made in U.S. Dollars by bank wire transfer in funds to an account designated by Paragon from time to time reasonably in advance of any payment due date.

4.5

Taxes.

(a)

The Parties agree to reasonably cooperate with one another and use commercially reasonable efforts to minimize obligations for any and all income or other taxes required by Applicable Law to be withheld or deducted from any Royalty Payments, Milestone Payments or other payments made by Apogee to Paragon or its designee(s) under this Agreement, including by completing commercially reasonable procedural steps, and taking commercially reasonable measures, to reasonably ensure that any withholding tax is reduced or eliminated to the extent permitted under Applicable Law, including income tax treaty provisions and related procedures for claiming treaty relief. To the extent that Apogee is required to deduct and withhold taxes with respect to any payment to Paragon or its designee(s), Apogee shall: (i) deduct and withhold such taxes from such payment to Paragon or its designee(s), (ii) remit the amount of such taxes to the proper government authority in accordance with Applicable Law, and (iii) promptly submit to Paragon an official tax certificate or other reasonably available evidence of such deduction and withholding to enable Paragon or its designee(s) to claim such payment of taxes. For the avoidance of doubt, Apogee’s remittance of such withheld amounts to the appropriate governmental authority shall be treated as payment of such amounts to Paragon or its designee(s), as applicable, for all purposes of this Agreement.

(b)

Apogee shall provide Paragon with commercially reasonable assistance in order to allow Paragon or its designee(s) to recover, as permitted by Applicable Law, withholding taxes or similar obligations resulting from payments made hereunder or to obtain the benefit of any present or future treaty against double taxation which may apply to such payments. Paragon shall provide Apogee reasonably in advance of any payment with any tax forms with respect to itself, and shall cause its designee(s), as applicable, to so provide any such forms, in each case that may be reasonably necessary in order for Apogee to not withhold tax or to withhold tax at a reduced rate under an applicable bilateral tax income treaty.

(c)

Notwithstanding any provision of this Agreement or the [***] Agreement to the contrary, as between the Parties, Apogee shall not be responsible for, and Paragon shall be responsible for, any taxes, or increase in the amount of any taxes (including, without limitation, withholding taxes, value added taxes, or sales or use taxes) imposed with respect to any payment required to made under this Agreement and that is made to one or more designee(s) of Paragon that would not have been imposed, or would have been imposed at a lower rate, if such payment were made directly by Apogee to Paragon, to the extent not borne by such designee(s).

(d)

The Parties shall reasonably cooperate in good faith to allocate any consideration payable pursuant to this Agreement among the rights granted pursuant to this Agreement and to determine the character of the transactions contemplated by and the payments made pursuant to this Agreement (including payments made to [***]), in each case, for applicable tax purposes. In the event the Parties cannot agree on any such allocation or determination, such disagreement shall be resolved in accordance with Section 10.7. The Parties shall and shall cause their Affiliates to (i) timely file all tax returns in a manner consistent with such allocation and determination, and (ii) take no position contrary thereto on any applicable tax return or in any tax proceeding or otherwise, in each case, except to the extent required to do otherwise pursuant to a “determination” within the meaning of Section 1313(a) of the Internal Revenue Code of 1986, as amended (or any analogous provision of state, local or non-U.S. Applicable Law). In the event that any such allocation or determination is disputed by any tax authority, the Party receiving notice of the dispute shall promptly notify the other Party of the dispute.

(e)

For purposes of this Section 4.5, for the avoidance of doubt, any reference to a designee of Paragon shall include [***].

4.6

Foreign Exchange. If any currency conversion shall be required in connection with the calculation of amounts payable hereunder, such conversion shall be made using the exchange rates reported on the [***] Business Day prior the payment due date for the purchase and sale of Dollars, as reported by the Wall Street Journal (East Coast Edition).

4.7

Late Payments. Any amount owed by Apogee to Paragon under this Agreement that is not paid within the applicable time period set forth herein will accrue interest at the per annum rate of [***] percentage point above the then-applicable United States prime rate as quoted in the Wall Street Journal (East Coast Edition) (or if it no longer exists, a similarly authoritative source), calculated on a [***] basis, or, if lower, the highest rate permitted under Applicable Law.

4.8

Blocked Currency. If by Applicable Law of a country in which Net Sales occurred, conversion of funds into Dollars or transfer of funds from such country to the United States is restricted, forbidden or delayed for more than [***] days, then Apogee can elect, at its sole discretion, that the amounts accrued in such country and owed by Apogee to Paragon under this Agreement shall be paid to Paragon in such country in local currency by deposit in a local bank designated by Paragon, unless the Parties otherwise agree in writing.

4.9

Records; Inspection.

(a)

Apogee shall, and shall cause its applicable Affiliates to, create and keep complete and accurate records of its sales and other dispositions of all Apogee Products, including all records that are reasonably necessary for the purposes of calculating all payments due under this Agreement.

(b)

Upon reasonable advance written notice to Apogee, Paragon shall have the right to retain a nationally recognized (in the US) independent certified public accounting firm to perform on behalf of Paragon an audit, conducted in accordance with U.S. generally accepted accounting principles (GAAP), of such books and records of Apogee or its applicable Affiliates as may be reasonably necessary to verify the accuracy of any reports provided pursuant to Section 4.3 hereunder for any Calendar Quarter ending not more than [***] calendar months prior to the date of such request. Such audits shall not occur more frequently than [***] in each Calendar Year and shall not be conducted more than [***] with respect to any reporting period, in each case other than for cause. All information disclosed or observed during any audit pursuant to this Section 4.9 shall be the Confidential Information of Apogee, and Paragon shall cause the accounting firm to retain all such information as Confidential Information, including, if requested by Apogee, by requiring such accounting firm to enter into a customary confidentiality agreement with Apogee prior to the initiation of any such audit.

(c)

Upon completion of any audit hereunder, the accounting firm shall provide both Apogee and Paragon a written report disclosing whether the reports submitted by Apogee are correct or incorrect, whether the amounts paid are correct or incorrect, and in each case, the specific details concerning any discrepancies. No other information regarding Apogee’s records shall be provided to Paragon.

(d)

Paragon shall bear its internal expenses and the out-of-pocket costs for engaging such accounting firm in connection with performing such audits; provided, however, that if any such audit uncovers an underpayment by Apogee that exceeds [***] percent ([***]%) of the total owed for such payment or payment period, as applicable, then Apogee shall reimburse Paragon or its designee(s) for the amounts actually paid to such accounting firm for performing such audit.

(e)

If such accounting firm concludes that Apogee has in aggregate underpaid amounts owed to Paragon during the audited period, Apogee shall pay Paragon or its designee(s) the amount of the discrepancy within [***] days of the date Paragon delivers to Apogee such accounting firm’s written report and an invoice for such amounts. If such accounting firm concludes that Apogee has in aggregate overpaid amounts owed to Paragon during the audited period, then Apogee may, at its election, either credit such overpaid amount against any future payment obligation to Paragon or require Paragon to refund such amounts within [***] days.

ARTICLE V

INTELLECTUAL PROPERTY.

5.1

Ownership. As between the Parties, each Party will own and retain all right, title and interest in and to all Intellectual Property Rights owned or controlled by such Party as of the Effective Date or that come into the ownership or control of such Party during the Term outside the scope of this Agreement. Other than rights granted to Apogee under this Agreement with respect to the Licensed Antibody Technology, the Other Licensed Patents and the [***] IP, nothing in this Agreement shall affect Paragon’s rights in any Patents, Know-How or other Intellectual Property Rights owned or controlled by Paragon or its Affiliates, now or in the future. Other than rights granted to Paragon under this Agreement with respect to the Apogee Intellectual Property,

nothing in this Agreement shall affect Apogee’s rights in any Patents, Know-How or other Intellectual Property Rights owned or controlled by Apogee or its Affiliates, now or in the future.

5.2

Patent Prosecution.

(a)

Prosecution Generally. For the purpose of this Section 5.2, “prosecute” and “prosecution” shall include any patent interference, opposition, pre-issuance Third Party submission, ex parte re-examination, post-grant review, inter partes review or other similar proceeding, appeals or petitions to any board of appeals in a patent office, appeals to any court for any patent office decisions, reissue proceedings and applications for Patent term extensions and the like.

(b)

Prosecution of Licensed Antibody Patents. As between the Parties following the Effective Date, Apogee shall be solely responsible for, and have sole discretion over, preparing, filing, prosecuting and maintaining the Licensed Antibody Patents, in each case, at Apogee’s sole expense.

(i)

Coordination. Apogee shall provide Paragon with copies of all material correspondence from and to any patent office relating to the Licensed Antibody Patents, and Apogee shall provide Paragon with drafts of all proposed filings to any patent office with respect to such Licensed Antibody Patents in reasonably adequate time before submission of such filings for Paragon’s review and comment. Apogee will take into consideration Paragon’s reasonable comments prior to submitting such filings.

(ii)

Backup Right to Prosecute. Apogee shall notify Paragon of any decision not to prepare or file, or to abandon, cease prosecution or not maintain any Licensed Antibody Patent anywhere in the Territory. Apogee shall provide such notice at least [***] days prior to any filing or payment due date, or any other due date that requires action, in connection with such Licensed Antibody Patent. In such event, Paragon shall have a backup right, but not the obligation, to prepare, file, or continue prosecution or maintenance of, such Licensed Antibody Patent, at Paragon’s expense.

(iii)

Cooperation in Patent Prosecution. Each Party shall cooperate with the other Party in the preparation, filing, prosecution and maintenance of Licensed Antibody Patents, including in each case by providing the prosecuting Party with data and other information as appropriate and executing all necessary affidavits, assignments and other paperwork.

Paragon’s prosecution of any Paragon Patents shall be at Paragon’s sole expense. Notwithstanding the foregoing, in prosecuting any Paragon Patents, Paragon hereby agrees that during the Term, neither Paragon nor any of its Affiliates or licensees will file, or assist any Third Party in filing, any Patent that includes a claim that expressly recites the sequence of a Licensed Antibody or Derived Antibody other than as part of a Paragon Multispecific Antibody.

Consultation with Apogee. On a Scheduled Multispecific Patent-by-Scheduled Multispecific Patent basis during the ROFN Period and any applicable ROFN Negotiation Period, Paragon shall provide Apogee with copies of all material correspondence from and to any patent office relating to those certain Multispecific Patents owned or otherwise controlled by Paragon and set forth on Schedule 5.2(d) (such Multispecific Patents, the “Scheduled Multispecific Patents”), and Paragon shall provide Apogee with drafts of

all proposed filings to any patent office with respect to such Scheduled Multispecific Patents in reasonably adequate time before submission of such filings for Apogee’s review and comment. Paragon will consider Apogee’s reasonable comments prior to submitting such filings, but Paragon shall retain final decision-making authority with respect to the content of any such filings. Notwithstanding the foregoing, the rights of Apogee under this Section 5.2(d) shall terminate on a Scheduled Multispecific Patent-by-Scheduled Multispecific Patent basis to the extent that Apogee’s rights under Section 2.6 with respect to a ROFN Multispecific Antibody that is Covered by a Valid Claim of such Scheduled Multispecific Patent have terminated or expired in accordance with the terms of Section 2.6.

(e)

5.5

Common Interest Agreement. At the request of either Party to conduct the activities under this Article V, the Parties shall cooperate in good faith to enter into a customary common-interest agreement intended

The Receiving Party shall promptly notify the Disclosing Party upon discovery of any unauthorized use or disclosure of the Confidential Information of the Disclosing Party.

6.2

Exceptions. The Receiving Party’s obligations under Section 6.1 shall not apply to any Confidential Information of the Disclosing Party that the Receiving Party can prove by competent evidence: (a) is now, or hereafter becomes, through no act or failure to act on the part of the Receiving Party in breach of this Agreement, generally known or available; (b) is known by the Receiving Party at the time of receiving such information from the Disclosing Party; (c) is hereafter furnished to the Receiving Party by a Third Party, as a matter of right and without restriction on disclosure; or (d) is independently discovered or developed by the Receiving Party, without the aid, use or application of any Confidential Information of the Disclosing Party.

Effect of Termination of this Agreement. If this Agreement terminates for any reason (excluding expiration under Section 8.1), whether with respect to a particular Apogee Product, particular country or in its entirety, then the following shall apply:

(a)

All licenses and other rights granted by Paragon to Apogee under this Agreement with respect to the terminated Apogee Product(s) and terminated country(ies) shall terminate, except as required for Apogee, its Affiliates and/or its Sublicensees to perform any of its obligations that survive termination, including to continue to complete or wind down any ongoing clinical trials for any Apogee Product, as may be required by Applicable Law or ethical principles.

(b)

No later than [***] days after the effective date of such termination, each Party shall return or cause to be returned to the other Party, or destroy, all Confidential Information received from the other Party and all copies thereof related to the terminated Apogee Product(s) in the terminated country(ies); provided, however, that each Party may retain any Confidential Information reasonably necessary for such Party’s ongoing obligations and rights under this Agreement which do not terminate, and each Party may keep one (1) copy of Confidential Information received from the other Party in its confidential files for record purposes and such copy shall remain subject to Article VI of this Agreement.

(c)

If this Agreement is terminated in its entirety, then upon [***] (which must be provided to [***] within [***] days after the effective date of termination), Paragon and Apogee shall [***] discuss in good faith, for a period of up to [***] days following such written request, terms and conditions under which Apogee may be willing to grant to Paragon [***], [***] license under the Apogee Intellectual Property to Develop, Manufacture, Commercialize and otherwise exploit the Apogee Products in the Field in the Territory that were the subject of any Development, Manufacturing or Commercialization activities performed by Apogee or its Affiliates under this Agreement prior to such termination (“Reversion Products”), as well as the potential transfer of materials, ongoing clinical trials and applicable regulatory filings and relevant data generated by Apogee with respect to the Reversion Products and necessary for the Development, Manufacture, Commercialization or other

exploitation of such Reversion Products, such agreement to include commercially reasonable financial and other terms (including the granting of a right of reference and the exchange of pharmacovigilance information, as applicable), which terms shall take into consideration Apogee’s contributions made in the Development, Manufacture, Commercialization and other exploitation of the Reversion Products.

8.7

Survival of Sublicenses. Upon termination of this Agreement, at the written request of any Sublicensee who is not then in breach of its sublicense agreement, such sublicense agreement will survive such termination of this Agreement, and Paragon will negotiate [***] the terms and conditions of a direct license with such Sublicensee that is consistent with the terms of this Agreement (as adjusted for the scope of license, products, field of use and other provisions of the original sublicense). For clarity, Paragon shall have no obligation with respect to any Sublicensee that is greater than or in addition to the obligations of Paragon to Apogee under this Agreement.

8.8

Accrued Rights; Survival. The expiration or termination of this Agreement for any reason shall not release either Party from any liability or obligation that, at the time of such expiration or termination, has already accrued to the other Party or that is attributable to a period prior to such expiration or termination, nor will expiration or any termination of this Agreement preclude either Party from pursuing all rights and remedies it may have under this Agreement, or at law or in equity, with respect to breach of this Agreement. In the event of expiration or any termination of this Agreement, the following provisions of this Agreement shall survive such expiration or termination in accordance with their respective terms and conditions: Article I (Definitions); Section 2.1 (License Grants from Paragon) (upon expiration (but not termination) of this Agreement as set forth in Section 8.1 (Term)); Section 2.2 (Sublicenses) (with respect to any payments or other performance obligations prior to conversion (if any) to a direct license pursuant to Section 8.7); Section 2.3 (No Implied Licenses; Reservation of Rights); Section 2.7(b) (Third Party In-Licenses) (with respect to any outstanding payment obligations that have accrued prior to the date of expiration or termination or that accrue following expiration); Section 2.9(a) (Election Notice Under the [***] Agreement) (with respect to any outstanding payment obligations that have accrued prior to the date of termination); Section 2.9(e) (Payments Under the [***] Agreement) (with respect to any outstanding payment obligations that have accrued prior to the date of expiration or termination or that accrue following expiration); Section 2.10 (Use of Licensed Antibody Technology and Paragon’s Confidential Information) (upon expiration (but not termination) of this Agreement as set forth in Section 8.1 (Term)); Section 4.1 (Milestone Payments) (with respect to any outstanding payment obligations that have accrued prior to the date of termination or expiration); Section 4.2 (Royalties) (with respect to any outstanding payment obligations that have accrued prior to the effective date of termination); Section 4.3 (Payment Reports) (with respect to any Royalty Payments that have accrued prior to the date of termination or expiration); Sections 4.4 (Payment Method) to 4.8 (Blocked Currency) (for the duration of any outstanding payment obligations under this Agreement); Section 4.9 (Records; Inspection) (for the duration set forth therein); Section 5.1 (Ownership); Section 5.2(d) (Patent Prosecution Costs Prior to the Effective Date); Section 5.2(g) (CREATE Act); Article VI (Protection of Confidential Information) (for the duration set forth therein); Section 7.3 (Disclaimer of Warranties); Section 8.6 (Effect of Termination of this Agreement); Section 8.7 (Survival of Sublicenses); this Section 8.8 (Accrued Rights; Survival); Article IX (Indemnification); and Article X (Miscellaneous).

ARTICLE IX

INDEMNIFICATION.

9.1

By Apogee. Apogee hereby agrees to defend, indemnify and hold harmless Paragon, its Affiliates and its or their Representatives (each, an “Paragon Indemnitee”) from and against any and all losses, damages,

liabilities, expenses and costs, including reasonable legal expense and attorneys’ fees (collectively, “Losses”), to which any Paragon Indemnitee may become subject as a result of any claim, demand, action, or other proceeding by any Third Party (“Third Party Claim”) to the extent such Losses result from: (a) the gross negligence, recklessness or willful misconduct of any Apogee Indemnitee in the performance of this Agreement; (b) Apogee’s breach of any of its representations, warranties or covenants under this Agreement; (c) Apogee’s Development, Manufacture, Commercialization or other exploitation of Apogee Products (but, for clarity, (i) excluding any activities conducted by Paragon under this Agreement or the Option Agreement and, (ii) except as otherwise expressly provided in this Agreement, excluding Losses related to any taxes imposed on or with respect to Paragon or its designee(s) as a result of payments made to Paragon or such designee(s) under this Agreement); or (d) any breach of the [***] Agreement that is caused by the actions or omissions of Apogee or its Affiliates and Sublicensees, in each case ((a) to (d)), except in each case to the extent that any such Losses are indemnifiable by Paragon under Section 9.2.

9.2

By Paragon. Paragon hereby agrees to defend, indemnify, and hold harmless Apogee, its Affiliates, and its or their Representatives (each, an “Apogee Indemnitee”) from and against any and all Losses to which any Apogee Indemnitee may become subject as a result of any Third Party Claim to the extent such Losses result from: (a) the gross negligence, recklessness or willful misconduct of any Paragon Indemnitee in the performance of this Agreement; or (b) Paragon’s breach of any of its representations, warranties or covenants under this Agreement; in each case ((a) to (b)), except in each case to the extent that any such Losses are indemnifiable by Apogee under Section 9.1.

9.3

Indemnification Procedures. The Party claiming indemnity under this Article IX (the “Indemnified Party”) will give written notice to the Party from whom indemnity is being sought (the “Indemnifying Party”) promptly after learning of the Third Party Claim for which indemnity is being sought (“Claim”). The Indemnifying Party’s obligation to defend, indemnify and hold harmless pursuant to Section 9.1 or Section 9.2, as applicable, will be reduced to the extent the Indemnified Party’s delay in providing notification pursuant to the previous sentence results in material prejudice to the Indemnifying Party; provided, however, that the failure by an Indemnified Party to give such notice or otherwise meet its obligations under this Section 9.3 will not relieve the Indemnifying Party of its indemnification obligation under this Agreement. At its option, the Indemnifying Party may assume the defense and have exclusive control, at its own expense, of any Claim for which indemnity is being sought by giving written notice to the Indemnified Party within [***] days after receipt of the notice of the Claim, provided, that (a) it agrees to indemnify the Indemnified Party from and against all Losses the Indemnified Party may suffer arising out of the Claim; (b) the Claim involves only money damages and does not seek an injunction or other equitable relief against the Indemnified Party; and (c) the Indemnifying Party conducts the defense of the Claim diligently. The Indemnified Party will provide the Indemnifying Party with reasonable assistance, at the Indemnifying Party’s expense, in connection with the defense. The Indemnified Party may participate in and monitor such defense with counsel of its own choosing at its sole expense; provided, however, the Indemnifying Party will have the right to assume and conduct the defense of the Claim with counsel of its choice. The Indemnifying Party will not settle any Claim without the prior written consent of the Indemnified Party, not to be unreasonably withheld, unless the settlement involves only the payment of money. The Indemnified Party will not settle any such Claim without the prior written consent of the Indemnifying Party. If the Indemnifying Party does not assume and conduct the defense of the Claim as provided above, (i) the Indemnified Party may defend against, and consent to the entry of any judgment or enter into any settlement with respect to the Claim in any manner the Indemnified Party may deem reasonably appropriate (and the Indemnified Party need not consult with, or obtain any consent from, the Indemnifying Party in connection therewith), and (ii) the Indemnified Party reserves any right it may have under this Article IX to obtain indemnification from the Indemnifying Party.

9.4

Limitation of Liability. EXCEPT FOR LIABILITY FOR BREACH OF Article VI, FRAUD OR WILLFUL MISCONDUCT OR FOR INDEMNIFICATION CLAIMS UNDER THIS Article IX, IN NO EVENT SHALL EITHER PARTY BE ENTITLED TO RECOVER FROM THE OTHER PARTY ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES IN CONNECTION WITH THIS AGREEMENT, EVEN IF THE OTHER PARTY HAD NOTICE OF THE POSSIBILITY OF SUCH DAMAGES.

9.5

Insurance. Apogee shall maintain at its expense insurance coverage consistent with normal business practices and adequate to cover the risks associated with its performance of any activities hereunder, and Apogee acknowledges and agrees that the maintenance of such insurance coverage shall not relieve Apogee of its obligations under this Agreement.

ARTICLE X

MISCELLANEOUS.

10.1

Independent Contractor Relationship. Paragon’s relationship with Apogee is that of an independent contractor, and nothing in this Agreement should be construed to create a partnership, joint venture, or employer-employee relationship. Neither Party is an agent of the other Party or authorized to make any representation, contract, or commitment on behalf of the other Party.

10.2

Force Majeure. Neither Party will be charged with any liability for delay or failure in performance of an obligation under this Agreement (other than any obligation to pay monies when due) to the extent such delay or failure is due to a cause beyond the reasonable control of the affected Party, such as war, riots, labor disturbances, epidemic, pandemic, fire, explosion, and compliance in good faith with any Applicable Law (in each case, a “Force Majeure”). The Party affected by a Force Majeure will give prompt written notice to the other Party of the nature of the cause of any material delay or failure to perform, its anticipated duration and any action being taken to avoid or minimize the effect. The Party affected will use its diligent efforts to avoid or remove such causes of delay or failure to perform and to mitigate the effect of such occurrence, and will continue performance in accordance with the terms of this Agreement whenever such causes are removed. The Party affected will give prompt written notice to the other Party of such resumed performance. If any such failure or delay in a Party’s performance hereunder continues for more than [***] days, the other Party may terminate this Agreement upon written notice to the affected Party.

10.3

Entire Agreement; Amendment. This Agreement, together with all Exhibits attached hereto, constitutes the final, complete, and exclusive agreement of the Parties with respect to the subject matter hereof and supersedes all prior and contemporaneous understandings and agreements, relating to its subject matter. This Agreement (including its Exhibits) may not be changed, modified, amended, or supplemented except by a written instrument signed by both Parties.

10.4

Non-Waiver. The failure of a Party to insist upon strict performance of any provision of this Agreement or to exercise any right arising out of this Agreement shall neither impair that provision or right nor constitute a waiver of that provision or right, in whole or in part, in that instance or in any other instance. Any waiver by a Party of a particular provision or right shall be in writing, shall be as to a particular matter and, if applicable, for a particular period of time and shall be signed by such Party.

10.5

Severability. Should one or more of the provisions of this Agreement become void or unenforceable as a matter of Applicable Law, then this Agreement shall be construed as if such provision were not contained herein and the remainder of this Agreement shall be in full force and effect, and the Parties will use their best efforts to substitute for the invalid or unenforceable provision a valid and enforceable provision which conforms as nearly as possible with the original intent of the Parties.

10.6

Assignment. Neither this Agreement nor any rights or obligations hereunder may be assigned by either Party without the prior written consent of the other Party (which consent shall not be unreasonably withheld); provided, however, that (a) Paragon may assign to an Affiliate or a Third Party its rights to receive some or all of the royalty and milestone payments payable hereunder together with the right to receive the terms and conditions of this Agreement, the payment reports of Apogee, results of any audit of Apogee and any other Confidential Information of Apogee relevant to the assigned payments, including the timing, duration or amounts thereof, subject to appropriate confidentiality provisions substantially equivalent to those in this Agreement; and (b) either Party may assign this Agreement without the other Party’s consent to (i) its Affiliates or (ii) its successor to all or substantially all of the business of such Party to which this Agreement relates, whether by merger, sale of stock, sale of assets or otherwise. The assigning Party shall provide the other Party with prompt written notice of any such assignment. Except for an assignment pursuant to clause (a) above, the rights and obligations of the Parties under this Agreement shall be binding upon and inure to the benefit of the successors and permitted assigns of the Parties, and the name of a Party appearing herein will be deemed to include the name of such Party’s successors and permitted assigns to the extent necessary to carry out the intent of this section. Any assignment not in accordance with this Agreement shall be void.

10.7

Dispute Resolution. The Parties recognize that a bona fide dispute as to certain matters may arise from time to time during the Term relating to either Party’s rights or obligations hereunder or otherwise relating to the validity, enforceability or performance of this Agreement, including disputes relating to alleged breach or termination of this Agreement but excluding any disputes relating to Article VI or disputes relating to the determination of the validity, scope, infringement, enforceability, inventorship or ownership of the Parties’ respective Intellectual Property Rights (hereinafter, a “Dispute”). In the event of the occurrence of any Dispute, the Parties will follow the following procedures in an attempt to resolve the dispute or disagreement:

(a)

The Party claiming that such a Dispute exists will give notice in writing (a “Notice of Dispute”) to the other Party of the nature of the Dispute.

(b)

The Dispute will be referred to the then Chief Executive Officer of Paragon (or such individual’s designee) and the then Chief Executive Officer of Apogee (or such individual’s designee) who will

meet no later than [***] days following the initial receipt of the Notice of Dispute and use reasonable endeavors to resolve the Dispute.

(c)

If, within [***] days of initial receipt of the Notice of Dispute, the Dispute has not been resolved, or if, for any reason, the meeting described in Section 10.7(b) hereof has not been held within [***] days of initial receipt of the Notice of Dispute, then the Parties agree that such Dispute will be finally resolved through binding arbitration to be administered by JAMS pursuant to its Comprehensive Arbitration Rules and Procedures and in accordance with the Expedited Procedures in those Rules, as specifically modified by the provisions of this Section 10.7(c). The arbitration will be conducted by a panel of three arbitrators. Within [***] days after the initiation of the arbitration, each Party will nominate one person to act as arbitrator, and the two arbitrators so named will then jointly appoint the third arbitrator within [***] days of their appointment, who will serve as chairman of the panel. All three arbitrators must be independent Third Parties having at least [***] years of dispute resolution experience (which may include judicial experience) or legal or business experience in the biotech or pharmaceutical industry. If either Party fails to nominate its arbitrator, or if the arbitrators selected by the Parties cannot agree on a person to be named as chairman within such [***]-day period, JAMS will make the necessary appointments for such arbitrator(s) or the chairman. Once appointed by a Party, such Party will have no ex parte communication with its appointed arbitrator. The place of arbitration will be in Boston, Massachusetts or such other venue as the Parties may mutually agree. The arbitration proceedings and all communications with respect thereto will be in English. Any written evidence originally in another language will be submitted in English translation accompanied by the original or a true copy thereof. The arbitrators have the power to decide all matters in Dispute, including any questions of whether or not such matters are subject to arbitration hereunder. The arbitration will be governed by the Federal Arbitration Act, 9 U.S.C. §§1 et seq., and judgment upon the award rendered by the arbitrators may be entered in any court having competent jurisdiction thereof. The existence, content and results of any arbitration proceedings pursuant to this Section 10.7 will be deemed the Confidential Information of both Parties.

(d)

Notwithstanding any provision of this Agreement to the contrary, either Party may immediately initiate litigation in any court of competent jurisdiction seeking any remedy at law or in equity, including the issuance of a preliminary, temporary or permanent injunction, to preserve or enforce its rights under this Agreement.

(e)

The Parties agree that any disputes relating to Article VI or disputes relating to the determination of the validity, scope, infringement, enforceability, inventorship or ownership of the Parties’ respective Intellectual Property Rights shall be subject to the exclusive jurisdiction of the state and federal courts in Boston, Massachusetts and each Party hereby submits to such jurisdiction.

10.8

Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts without reference to conflicts of laws principles.

10.9

Any notice to be given under this Agreement must be in writing and delivered either in person, by internationally recognized express courier, by email, or by facsimile, to the Party to be notified at its address(es) given below, or at any address such Party has previously designated by prior written notice to the other.
