3.4(a)Collectively, the rights granted to LICENSEE under Section 3.1, Section 3.2 and Section 3.3 shall be the “LICENSE”.  The LICENSE is further subject to all the terms and conditions of this AGREEMENT, including, without limitation, YALE’s right to terminate the LICENSE if a TERMINATION EVENT has occurred and is continuing by reason of, among other things, LICENSEE’s failure to pay all amounts due to YALE pursuant to Articles 5, 6, and 10 and LICENSEE’s failure to comply with Section 7.5.

(b)Part of the consideration received by YALE for the grant of the LICENSE is LICENSEE’s obligation under the RESEARCH AGREEMENT to provide RESEARCH SUPPORT in the aggregate amount of Nine Million Dollars ($9,000,000), consisting of One Million Five Hundred Thousand Dollars per year over the six-year period provided in the RESEARCH AGREEMENT, with all such consideration having been paid prior to the EFFECTIVE DATE.  As of the EFFECTIVE DATE, the RESEARCH AGREEMENT has expired and is of no further force or effect.

3.5To the extent that any invention included within the LICENSED PATENTS has been funded in whole or in part by the United States government, the United States government retains certain rights in such invention as set forth in 35 U.S.C. §200-212 and all regulations promulgated thereunder, as amended, and any successor statutes and regulations (the “FEDERAL PATENT POLICY”).  As a condition of the grant of the LICENSE, LICENSEE acknowledges and shall comply with all aspects of the FEDERAL PATENT POLICY applicable to the LICENSED PATENTS, including the obligation that PRODUCTS IN CLASS used or sold in the United States be manufactured substantially in the United States.  Nothing contained in this AGREEMENT obligates or shall obligate YALE to take any action that would conflict in any respect with its past, current or future obligations to the United States Government under the FEDERAL PATENT POLICY with respect to the LICENSED PATENTS.

​

​

(a)the date on which the last of the VALID CLAIMS of the patents included in the LICENSED PATENTS in such country expires, lapses or is declared to be invalid by a final decision of a court or other authority of competent jurisdiction, not subject to further appeal, through no fault or cause of LICENSEE; and

(b)the date that is fifteen (15) years after the last LICENSED KNOW-HOW, LICENSED MATERIALS, or LICENSED METHODS have been provided to LICENSEE by YALE under this AGREEMENT; and

(c)the date that is fifteen (15) years from the date of FIRST SALE of a PRODUCT IN CLASS;

but in no event shall the TERM end later than the date that is thirty (30) years after the ORIGINAL LICENSE AGREEMENT EFFECTIVE DATE.

3.8YALE hereby agrees that, after the EFFECTIVE DATE except for [*]-FUNDED PATENTS, YALE will not grant any third party (including [*]) any rights, for any therapeutic or prophylactic uses, in any LICENSED PATENTS.

3.9In the event that YALE materially breaches a representation or warranty contained in Section 1.2 with respect to the TECHNOLOGY (a “Section 1.2 Breach”), which in turn creates potential liability for LICENSEE (including, potentially, for its AFFILIATES or SUBLICENSEES) to YALE or a third party (“Section 1.2 Liability”), YALE hereby agrees it will never institute any action or suit at law or in equity against LICENSEE or its AFFILIATES or its SUBLICENSEES alleging Section 1.2 Liability with respect to the use by LICENSEE or its AFFILIATES or SUBLICENSEES of the component(s) of the TECHNOLOGY that was(were) the subject of the Section 1.2 Breach, nor institute, prosecute or in any way aid in the institution or prosecution of any claim, demand, suit, action, or cause of action for damages, costs, other compensation or injunctive relief for or on account of any Section 1.2 Liability, whether developed or undeveloped, resulting or to result, known or unknown, past, present or future, arising out of the use by LICENSEE or its AFFILIATES or its SUBLICENSEES of the component(s) of the TECHNOLOGY that was(were) the subject of the Section 1.2 Breach.  For the avoidance of doubt, the preceding sentence shall in no way limit LICENSEE’s ability to seek other remedies with respect to YALE, nor shall it in any way limit LICENSEE’s obligations to comply in good faith with all provisions of this AGREEMENT with which it is able to comply notwithstanding the Section 1.2 Breach.

ARTICLE 4. SUBLICENSES

4.1Any sublicense by LICENSEE of the rights granted to it under this AGREEMENT shall comply with the provisions of Sections 4.2, 4.3 and 4.4.

4.2Subject to Section 4.5, any sublicense granted by LICENSEE shall include terms under which the SUBLICENSEE agrees with the LICENSEE, and shall include provisions in favor

​

​

of LICENSEE, as sublicensor thereunder, substantially the same as are provided in Section 7.1, Section 7.2, Section 7.3, Section 7.4, Article 8, Section 9.1, Section 9.2, Section 10.6, Article 12 and Article 14 of this AGREEMENT with respect to the subject matter of such sublicense and the related definitions in this AGREEMENT.  LICENSEE will provide YALE with a copy of each sublicense agreement (and all amendments thereof) within thirty (30) days of execution of such agreement or amendment.  LICENSEE shall not be responsible for the performance of any SUBLICENSEE under any such sublicense and shall be obligated to pay royalties and other amounts that arise from such sublicense and are due to YALE only as and to the extent such SUBLICENSEE pays the same to LICENSEE.

4.3LICENSEE shall pay royalties to YALE on NET SALES of PRODUCTS IN CLASS by SUBLICENSEES based on the same royalty rate as apply to NET SALES by LICENSEE and its AFFILIATES under Article 6, regardless of the royalty rates payable by SUBLICENSEES to LICENSEE under a sublicense agreement.  In addition, LICENSEE shall pay to YALE the percentage of any SUBLICENSE INCOME with respect to PRODUCTS IN CLASS as set forth below (based on the stage of development that the INCLUDED PRODUCT CANDIDATE that is the subject of such sublicense has reached as of the effective date of the applicable sublicense agreement):

​

For clarity, the SUBLICENSE INCOME tiers set forth in the above table are not cumulative, and any payment made with respect to SUBLICENSE INCOME shall be made only with respect to the latest stage of developed reached by the applicable product candidate or product as of the effective date of the applicable sublicense agreement.  By way of example, if LICENSEE sublicenses rights to a product candidate after INITIATING a Phase 2 Study, but before INITIATING a Phase 3 Study, LICENSEE will only be required to pay under this Section 4.3 [*] ([*]%) SUBLICENSE INCOME from such sublicense (i.e., no additional payments for any earlier tiers will be due). For purposes of this Section 4.3, INITIATING shall mean the dosing of the first subject in the applicable PHASE 1 STUDY, PHASE 2 STUDY or PHASE 3 STUDY.  For clarity, LICENSEE’S obligation to pay a percentage of SUBLICENSE INCOME shall not apply to (i) any amounts received by LICENSEE from YALE under the KLOTHO RETURNED TECHNOLOGY AGREEMENT or (ii) any amounts that are not related to any of the INCLUDED PRODUCT CANDIDATES.

4.4LICENSEE agrees that it shall:

(a)within thirty (30) days of execution by the parties, provide YALE with a copy of any amendments to sublicenses granted by LICENSEE under this AGREEMENT, and within thirty (30) days after termination of any sublicense, notify YALE of such termination; and

​

​

(b)within thirty (30) days of receipt, provide complete copies of all reports provided to LICENSEE by SUBLICENSEES pursuant to any sublicense; provided, however, that LICENSEE may omit or redact from the copies so provided to YALE any portion of the reports of a SUBLICENSEE which portion contains information that LICENSEE would not have otherwise been required to report to YALE under Section 7.3 if such report were provided by LICENSEE directly; and

(c)use commercially reasonable efforts to seek compliance in all material respects by each SUBLICENSEE with the terms of the sublicense to which such SUBLICENSEE is a party.

(d)Pay to YALE any SUBLICENSE INCOME due hereunder within ninety (90) days after LICENSEE receives such SUBLICENSE INCOME. Notwithstanding the foregoing, if LICENSEE receives any SUBLICENSE INCOME that consists of EQUITY CONSIDERATION (or other non-cash consideration), LICENSEE shall at LICENSEE’s election, either promptly transfer YALE’s share of such EQUITY CONSIDERATION (or other non-cash consideration) to YALE, or sell YALE’s share of such EQUITY CONSIDERATION (or other non-cash consideration) for cash as soon as practicable in an arm’s length transaction at fair market value in accordance with applicable securities laws and regulations. Following such sale, LICENSEE shall then pay to YALE the cash actually received by LICENSEE in exchange for the EQUITY CONSIDERATION (or other non-cash consideration) within ninety (90) days of the date that LICENSEEreceived the proceeds from the sale of the EQUITY CONSIDERATION (or other non-cash consideration).

4.5If LICENSEE proposes to enter into a sublicense that does not include terms that require SUBLICENSEE thereunder to agree substantially as provided in Sections 7.1 and 7.2 of this AGREEMENT (and the related definitions) with respect to the subject matter of such sublicense, then LICENSEE shall submit the proposed form of such sublicense to YALE for review and approval prior to entering into such sublicense.  YALE’s review and approval of any such sublicense shall be limited to the terms of the due diligence obligations of SUBLICENSEE thereunder, provided that such sublicense otherwise complies with the requirements of Sections 4.2 and 4.3 of this AGREEMENT.  YALE shall notify LICENSEE of any objections it may have to the due diligence terms of a proposed sublicense within fifteen (15) days after LICENSEE submits such sublicense to YALE for its review and approval, and LICENSEE shall notify YALE of LICENSEE’s response to said objections within fifteen (15) days after receipt of YALE’s objections.  YALE shall not unreasonably withhold its consent to any such sublicense provided that LICENSEE substantively responds to YALE’s objections.

4.6Notwithstanding anything contained herein to the contrary and for the avoidance of doubt, LICENSEE shall not owe any royalties or other payments to YALE in respect of any amounts received by LICENSEE pursuant to the KLOTHO RETURNED TECHNOLOGY AGREEMENT.

(i), If IND APPROVAL of a TAM PRODUCT occurs prior to any CHANGE OF CONTROL, LICENSEE shall pay YALE a non-refundable milestone royalty of [*] Dollars ($[*]) when LICENSEE has collected at least [*]Dollars ($[*]) in NET SALES of such TAM

​

​

PRODUCT (and no further milestones shall then be due or payable in respect of any TAM PRODUCT); or

6.1During the TERM, and subject to the following sentence, as partial consideration for the LICENSE, LICENSEE shall pay to YALE an earned royalty on worldwide cumulative NET SALES of each PRODUCT IN CLASS or LICENSED METHOD developed by LICENSEE or its SUBLICENSEES or AFFILIATES equal to [*] percent ([*]%) of such NET SALES (the “EARNED ROYALTY”).  If for such a PRODUCT IN CLASS or LICENSED METHOD there

​

​

is not a VALID CLAIM in either a LICENSED PATENT or a LICENSEE PATENT, in each case claiming such PRODUCT IN CLASS or LICENSED METHOD, then the EARNED ROYALTY on such a PRODUCT IN CLASS or LICENSED METHOD shall be reduced (a “REDUCED EARNED ROYALTY”).  The REDUCED EARNED ROYALTY on worldwide cumulative NET SALES of each PRODUCT IN CLASS or LICENSED METHOD developed by LICENSEE or its SUBLICENSEES or AFFILIATES shall be equal to [*] percent ([*]%) of such NET SALES from and after the date there is no such VALID CLAIM.  Unless otherwise stated in this AGREEMENT, any reference to “EARNED ROYALTIES” shall refer to either or both EARNED ROYALTIES and REDUCED EARNED ROYALTIES, as the case may be.  For clarity, LICENSEE’S obligation to pay EARNED ROYALTIES shall not apply to any amounts that are not related to any of the INCLUDED PRODUCT CANDIDATES.

6.2Any obligation to pay the EARNED ROYALTIES to YALE on any PRODUCT IN CLASS or LICENSED METHOD pursuant to Article 6.1 which was incurred by LICENSEE prior to termination of this Agreement shall survive any early termination of this Agreement except in the case that such early termination is due to material breach of this Agreement by YALE.

6.3LICENSEE shall pay all EARNED ROYALTIES accruing to YALE within thirty (30) days from the end of each calendar quarter (March 31, June 30, September 30 and December 31), beginning in the first calendar quarter in which NET SALES occur.

6.4During the TERM, LICENSEE agrees to pay YALE annual Minimum Royalty Payments (“MRP”), commencing on the first anniversary of the ORIGINAL LICENSE AGREEMENT EFFECTIVE DATE to occur at least six (6) months after the date of the FIRST SALE of the first PRODUCT IN CLASS or first service using a LICENSED METHOD that results in NET SALES for such a first PRODUCT IN CLASS or LICENSED METHOD.

(a)If the PRODUCT IN CLASS or service using a LICENSED METHOD the FIRST SALE of which gives rise to LICENSEE’s obligation to pay an MRP is a therapeutic or prophylactic PRODUCT IN CLASS or service using a LICENSED METHOD, then the MRP shall be made according to the following schedule:

​

(b)If the PRODUCT IN CLASS or service using a LICENSED METHOD the FIRST SALE of which gives rise to LICENSEE’s obligation to pay an MRP is a diagnostic PRODUCT IN CLASS or service using a LICENSED METHOD, then the MRP shall be made according to the following schedule:

​

​

​

​

(c)Once the LICENSEE has made a FIRST SALE of both a therapeutic or prophylactic PRODUCT IN CLASS or a service using a LICENSED METHOD and a diagnostic PRODUCT IN CLASS or service using a LICENSED METHOD, then thereafter MRP shall be the sum of the amounts indicated in Sections 6.3(a) and 6.3(b).  If the FIRST SALE of a PRODUCT IN CLASS or service using a LICENSED METHOD is both a therapeutic or prophylactic and a diagnostic and such therapeutic or prophylactic PRODUCT IN CLASS or service using a LICENSED METHOD is, or is intended to be, marketed and sold separate from such diagnostic PRODUCT IN CLASS or service using a LICENSED METHOD, as the case may be, and such diagnostic PRODUCT IN CLASS or service using a LICENSED METHOD is, or is intended to be, marketed and sold for a use other than determining the suitability of the use of such therapeutic or prophylactic PRODUCT IN CLASS or service using a LICENSED METHOD in particular patients, then thereafter MRP shall be the sum of the amounts indicated in Sections 6.3(a) and 6.3(b).

(d)Once the MRP commences, LICENSEE shall continue to pay the MRP for PRODUCTS IN CLASS or services using LICENSED METHODS until the end of the TERM, subject to Section 6.3(e).  YALE shall fully credit MRP paid against any EARNED ROYALTIES payable by LICENSEE in the same year.

(e)If at any time after the MRP commences all PRODUCTS IN CLASS and services using a LICENSED METHOD for which a FIRST SALE has occurred are temporarily or permanently removed from the market and there is no longer any PRODUCT IN CLASS or service using a LICENSED METHOD subject to EARNED ROYALTY under the terms of this AGREEMENT, then the MRP due under Section 6.3 shall be suspended and LICENSEE shall resume payment of the applicable LMR under Section 5.2.  The payment of LMR as so resumed shall continue until such time as marketing of any removed PRODUCT IN CLASS or service using a LICENSED METHOD has resumed or LICENSEE shall have made a FIRST SALE of another PRODUCT IN CLASS or service using a LICENSED METHOD, subject to suspension of the MRP through subsequent operation of this Section 6.3(e).  MRP that is suspended or resumed and LMR that arises by reason of this Section 6.3(e), in any such case for a period of less than 12 months, shall be prorated.

(f)If at any time the applicable rate of EARNED ROYALTIES for all PRODUCTS IN CLASS and services using any LICENSED METHOD shall become the REDUCED EARNED ROYALTY, then the applicable MRP shall thereafter be [*] percent ([*]%) of the applicable amount from the above schedules, prorated for any period of less than 12 months.

6.5All EARNED ROYALTIES and other payments due under this AGREEMENT shall be paid to YALE in United States Dollars.  In the event that conversion from foreign currency is required in calculating a payment under this AGREEMENT, the exchange rate used shall be the Interbank rate quoted by Citibank, N.A. at the end of the last business day of the quarter in which the royalty was earned.  If overdue, the EARNED ROYALTIES and any other payments due under this AGREEMENT shall bear interest until payment at a per annum rate equal to [*], and YALE shall be entitled to recover reasonable attorneys’ fees and costs related to the collection of overdue

​

​

EARNED ROYALTIES or other overdue amounts payable by LICENSEE under this AGREEMENT, following such failure to pay.  The payment of such interest shall not foreclose YALE from exercising any other right it may have as a consequence of the failure of LICENSEE to make any payment when due.

All such applications or patents shall remain the property of YALE.

​

​

10.3If LICENSEE does not agree to pay the expenses of filing, prosecuting or maintaining a patent application or patent in any country outside the United States, or fails to pay the expenses of filing, prosecuting or maintaining a patent application or patent in the United States, then subject to compliance with Section 13.1, the LICENSE with respect to such patent application or patent shall terminate with respect to that country.

10.4The costs mentioned in Sections 10.2 and 10.3 shall include, but are not limited to, any past, present and future taxes, annuities, working fees, maintenance fees, renewal and extension charges.  Payment of such costs for shall be made, at YALE’s option, either directly to patent counsel or by reimbursement to YALE.  In either case, LICENSEE shall make payment directly to the appropriate party within thirty (30) days of receiving its invoice.  If LICENSEE fails to make payment to YALE or patent counsel, as appropriate, within the thirty (30) day period, LICENSEE shall be charged a five percent (5%) surcharge on the invoiced amount per month or fraction thereof or such other amount (higher or lower) as may be charged by patent counsel.  Failure of LICENSEE to pay the surcharge shall be grounds for termination by YALE under Section 13.1 as and to the extent the same constitutes a TERMINATION EVENT. For the avoidance of doubt and notwithstanding anything herein to the contrary, YALE shall be responsible for all costs related to the past, present and future filing, prosecution, maintenance and defense of the KLOTHO PATENTS and LICENSEE shall have no obligation under this Agreement for any of the costs related thereto.

ARTICLE 11. INFRINGEMENT AND LITIGATION

11.1Each party shall promptly notify the other in writing in the event that it obtains knowledge of infringing activity by third parties, or is sued or threatened with an infringement suit, in any country in the LICENSED TERRITORY as a result of activities that concern the TECHNOLOGY and shall supply the other party with documentation of the infringing activities that it possesses.

11.2During the TERM:

(a)LICENSEE shall have the first right in its sole discretion, but not any obligation to (i) defend its or its SUBLICENSEE’s use of the TECHNOLOGY against infringement or interference claims in the LICENSED TERRITORY by third parties and (ii) take action (including legal action) against third parties who may infringe the LICENSED PATENTS or otherwise misappropriate the LICENSED KNOW-HOW, LICENSED METHODS or LICENSED MATERIALS.  This right includes bringing any legal action for infringement and defending any counter claim of invalidity or action of a third party for declaratory judgment for non-infringement or non-interference.  If, in the reasonable opinion of both LICENSEE’s and YALE’s respective counsel, YALE is required to be a named party to any such suit for standing purposes, LICENSEE may join YALE as a party; provided, however, that (i) YALE shall not be the first named party in any such action, (ii) the pleadings and any public statements about the action shall state that the action is being pursued by LICENSEE and that LICENSEE has joined YALE as a party; and (iii) LICENSEE shall keep YALE reasonably apprised of all developments in any such action.  LICENSEE may settle such suits solely in its own name and solely at its own expense and through counsel of its own selection; provided, however, that no settlement shall be entered without YALE’s prior written consent, which shall not be unreasonably withheld.  LICENSEE shall bear the expense of such legal actions.  Except for providing reasonable assistance, at the request and expense of LICENSEE, YALE shall have no obligation regarding the legal actions described in this Section unless required to participate by law.  However, YALE shall have the right to participate in any such action through its own counsel and at its own expense.  Any recovery shall first be applied to LICENSEE’s out-of-pocket expenses and second shall be applied to YALE’s out-of-pocket expenses, including legal fees.  Thereafter, any remaining amount of such recovery by LICENSEE up to the amount of compensatory damages recovered by LICENSEE shall be retained by LICENSEE, but if related to a PRODUCT IN CLASS or LICENSED METHOD shall be deemed, to the extent so related, NET SALES of a PRODUCT IN CLASS or LICENSED METHOD, as the case may be, during the calendar quarter in which such recovery is actually paid to LICENSEE, and shall be subject to payment by LICENSEE of an EARNED ROYALTY thereon pursuant to Section 6.1.  LICENSEE shall pay YALE [*] percent ([*]%) of the amount, if any, of any such recovery by LICENSEE related to a PRODUCT IN CLASS or LICENSED METHOD which amount is in excess of (i) LICENSEE’s and YALE’s out-of­pocket expenses as aforesaid and (ii) the amount of such compensatory damages as aforesaid.  LICENSEE shall make such payment to YALE within thirty (30) days after the end of the calendar quarter in which LICENSEE actually receives the amount giving rise to such payment to YALE.

​

​

(b)Promptly after LICENSEE (a) receives notification from YALE of infringement by a third party or (b) otherwise first becomes aware of an infringement by a third party, whichever is earlier, LICENSEE shall investigate such infringement and take other steps, including, without limitation, contacting the person believed to be infringing, to determine the nature and extent of any such infringement and, if LICENSEE determines that such infringement is occurring, notify such infringing person to cease.  If such infringement shall nonetheless continue, then LICENSEE shall proceed in a timely manner in accordance with Section 11.2(a).  If LICENSEE shall fail to take such action or commence such legal action, as the case may be, within sixty (60) days after such demand by YALE, then YALE shall have the right to take such action or to initiate such legal action, as the case may be, at its own expense.  If YALE initiates such legal action YALE may use the name of LICENSEE as party plaintiff to uphold the LICENSED PATENTS.  In such case, LICENSEE shall provide reasonable assistance to YALE if requested to do so.  YALE may settle such actions solely through its own counsel.  Any recovery shall be retained by YALE.  In case YALE initiates such legal action in accordance with this Section 11.2(6), then YALE may terminate the LICENSE in the country where such legal action is taken.

11.3In the event LICENSEE is permanently enjoined from exercising its LICENSE under this AGREEMENT pursuant to an infringement action brought by a third party, or if both LICENSEE and YALE elect not to undertake the defense or settlement of a suit alleging infringement for a period of six (6) months from notice of such suit, then either party shall have the right to terminate the LICENSE in the country where the suit was filed with respect to the allegedly infringing LICENSED PATENT following thirty (30) days’ written notice to the other party in accordance with the terms of Article 15.

11.4If LICENSEE, AFFILIATE, and/or SUBLICENSEE challenge a VALID CLAIM of a LICENSED PATENT or challenge a claim by YALE that a product is a PRODUCT IN CLASS (each a “CHALLENGE”), then LICENSEE, AFFILIATE, and/or SUBLICENSEE shall pay or continue to pay all amounts due under this AGREEMENT during the pendency of such CHALLENGE, whether or not any of such amounts is in dispute in such CHALLENGE.

​

ARTICLE 12. USE OF YALE’S NAME

LICENSEE shall not use the name “Yale” or “Yale University,” nor any variation or adaptation thereof, nor any trademark, trade name or other designation owned by YALE, nor the names of any of its trustees, officers, faculty, students, employees or agents, for any purpose without the prior written consent of YALE in each instance, except (a) that LICENSEE may disclose the terms of this AGREEMENT, the activities of the parties hereunder, and the TECHNOLOGY to its stockholders, potential investors and consultants who are subject to obligations to LICENSEE to keep such information confidential, where such confidentiality obligations are substantially similar to the obligations of LICENSEE to YALE hereunder and (b) as required by applicable law.

ARTICLE 13. TERMINATION

13.1YALE shall have the right to terminate the LICENSE upon written notice to

​

​

LICENSEE in the event a TERMINATION EVENT shall have occurred and be continuing; provided, however, that any termination by reason of a TERMINATION EVENT (other than a TERMINATION EVENT described in Section 2.67(a)) shall be made in accordance with Section 13.4.

13.2The LICENSE shall terminate automatically without any notice to LICENSEE in the event LICENSEE shall cease to carry on its business for a period of thirty (30) consecutive days or becomes INSOLVENT, or a petition in bankruptcy is filed against LICENSEE and is consented to, acquiesced in or fails to be dismissed within one hundred twenty (120) days, or LICENSEE makes a general assignment for the benefit of creditors, or a receiver is appointed for LICENSEE.

13.3LICENSEE shall have the right to terminate the LICENSE upon written notice to YALE:

(a)at any time on six (6) months’ notice to YALE, provided LICENSEE is not in breach of the AGREEMENT in any material respect and upon payment of all amounts due YALE through the effective date of termination; or

(b)in the event YALE commits a material breach of any of the provisions of this AGREEMENT and such breach is not cured (if capable of being cured) within the sixty (60) day period after receipt of written notice thereof from LICENSEE which notice shall identify such breach in reasonable detail, or upon receipt of such notice if such breach is not capable of being cured.

13.4Subject to Section 13.1, if YALE believes that a TERMINATION EVENT (other than a TERMINATION EVENT described in Section 2.67(a)) shall have occurred and be continuing, then such matter shall be resolved in accordance with this Section 13.4.

(a)If YALE believes such a TERMINATION EVENT shall have occurred and be continuing and wishes to obtain additional information from LICENSEE to assess whether such a TERMINATION EVENT shall have occurred and be continuing, then YALE may so notify LICENSEE and request such information as YALE may specify in such notice to assist YALE in determining whether such a TERMINATION EVENT shall have occurred and be continuing (each a “TERMINATION EVENT INFORMATION NOTICE”).  LICENSEE shall respond to such TERMINATION EVENT INFORMATION NOTICE within thirty (30) days and in such response shall provide such information as YALE shall have requested and which LICENSEE has in its possession or may obtain without unreasonable effort or expense.

(b)If either (1) notwithstanding LICENSEE having provided such additional information, YALE continues to believe such a TERMINATION EVENT shall have occurred and be continuing or (2) YALE believes such a TERMINATION EVENT shall have occurred and be continuing and does not wish to obtain additional information from LICENSEE under Section 13.4(a), then in either such case in the preceding clause (1) or (2) YALE may give notice to LICENSEE stating that YALE believes that such a TERMINATION EVENT shall have occurred and be continuing and setting forth in reasonable detail the basis for YALE’s belief that such a TERMINATION EVENT shall have occurred and be continuing (each a

​

​

“TERMINATION EVENT NOTICE”).  Within thirty (30) days after LICENSEE receives a TERMINATION EVENT NOTICE, LICENSEE shall provide YALE such information as LICENSEE believes establishes the absence of such a TERMINATION EVENT having occurred and be continuing.

(c)YALE shall give a TERMINATION EVENT INFORMATION NOTICE (or if YALE determines not to give a TERMINATION EVENT INFORMATION NOTICE, then a TERMINATION EVENT NOTICE) within ninety (90) days after (1) the cure period, in the case of such a notice relating to Section 2.67(b), (2) YALE first learns of the event, in the case of such a notice relating to Section 2.67(c) or 2.67(e), (3) LICENSEE’s notice to YALE, in the case of such a notice relating to Section 2.67(d), or (4) it receives LICENSEE’s annual progress report, in the case of such a notice relating to Section 7.2 or 7.5, or the due date for LICENSEE’s annual progress report, in case LICENSEE fails to provide any such report when due.  If YALE gives a TERMINATION EVENT INFORMATION NOTICE, then it shall give any TERMINATION EVENT NOTICE relating thereto within 60 days after giving such TERMINATION EVENT INFORMATION NOTICE.

(d)Within sixty (60) days after LICENSEE receives a TERMINATION EVENT NOTICE, YALE and LICENSEE shall meet at YALE’s campus in New Haven, Connecticut to discuss and seek to resolve the matter.  If, after such meeting the parties are unable to resolve such matter, then the Managing Director of YALE’s Office of Cooperative Research, or the Managing Director’s designee, and the Chairman of the Board, the Chief Executive Officer or the President or another designee of LICENSEE shall meet at YALE’s campus in New Haven, Connecticut and seek to resolve such matter.

(e)if, after following the procedures specified in this Section 13.4 with respect to an alleged TERMINATION EVENT of the type covered by this Section 13.4, the parties are unable to resolve the matter and YALE continues to believe that such a TERMINATION EVENT has occurred and is continuing, then YALE shall so notify LICENSEE within thirty (30) days after conclusion of the meetings provided for in Section 13.4(d).  Such notice shall specify in reasonable detail the TERMINATION EVENT(S) alleged to have occurred and be continuing.  After YALE gives such notice, the parties shall submit the dispute to JAMS or another such mutually agreed upon alternative dispute resolution provider experienced in business dispute mediation (an “ADR”) for non-binding mediation.  The parties will cooperate with ADR and with one another in selecting a mediator from ADR’s panel of neutrals, and in promptly scheduling the mediation proceedings.  The parties covenant that they will participate in the mediation in good faith, and that they will share ADR costs equally.  All offers, promises, conduct and statements, whether oral or written, made in the course of the mediation by any of the parties, their agents, employees, experts and attorneys, and by the mediator or any ADR employees, are confidential, privileged and inadmissible for any purpose, including impeachment, in any arbitration or other proceeding involving the parties, provided that evidence that is otherwise admissible or discoverable shall not be rendered inadmissible or non-discoverable as a result of its use in the mediation.  If the dispute is not resolved within ninety (90) days from the date of the submission of the dispute to mediation (or such later date as the parties may mutually agree in writing), then if such TERMINATION EVENT shall be continuing YALE shall have the right to terminate the LICENSE by giving fifteen (15) days’ notice to LICENSEE, which notice shall specify in reasonable detail the particular TERMINATION EVENT(S) (the “TERMINATION

​

​

NOTICE”).  The mediation may continue, if the parties so agree, after YALE gives the TERMINATION NOTICE.  The pendency of a mediation shall not preclude a party from seeking provisional remedies in connection with this AGREEMENT or such dispute from a court of competent jurisdiction, and the parties agree not to defend against any application for provisional relief on the ground that a mediation is pending.

(f)Either party shall have the right to seek declaratory relief relating to this AGREEMENT in a court of competent jurisdiction.

13.5Upon termination of the LICENSE, for any reason, all rights and licenses granted to LICENSEE under the terms of this AGREEMENT shall terminate except as provided below in this Section 13.5 and in Section 13.9.  In case of any termination of the LICENSE, each sublicense that LICENSEE shall have entered into in compliance with this AGREEMENT shall become a direct license by YALE to the applicable SUBLICENSEE, so long as at the time of such termination of the LICENSE such SUBLICENSEE shall be in compliance in all material respects with the terms of its sublicense; provided, however that (1) YALE shall not be liable for any breach or default under such sublicense by LICENSEE and (2) in no event shall YALE have any obligation or liability under such sublicense that it did not have to LICENSEE under this AGREEMENT prior to termination of the LICENSE.  Upon such termination, LICENSEE shall cease to manufacture or sell PRODUCTS IN CLASS and cease to practice LICENSED METHODS, except that (1) LICENSEE may complete the manufacture of quantities of PRODUCTS IN CLASS which were work-in-process on the date of such termination and (2) LICENSEE may, for up to one hundred eighty (180) days after the date of such termination, sell any inventory of PRODUCTS IN CLASS that existed on the date of such termination or which were completed as permitted by the immediately preceding clause (1).  Within sixty (60) days of the effective date of termination LICENSEE shall:

(a)Provide to YALE the last report required under Section 9.1; and

(b)Make all payments arising under this AGREEMENT up to the effective date of termination.

13.6Termination of the LICENSE shall not affect any rights or obligations accrued prior to the effective date of such termination and specifically LICENSEE’s obligation to pay all royalties and other payments specified by Article 5 and 6 for NET SALES to the date of termination, or as provided pursuant to Articles 5.9 and 6.2 in the case of any early termination.   The parties agree that claims giving rise to indemnification may arise after the TERM or termination of the LICENSE granted herein.

13.7The rights provided in this Article 13 shall be in addition and without prejudice to any other rights which the parties may have with respect to any default or breach of the provisions of this AGREEMENT.

13.8Waiver by either party of one or more defaults or breaches shall not deprive such party of the right to terminate because of any subsequent default or breach.

(a)Upon termination of the LICENSE for any reason other than breach by YALE, the TECHNOLOGY that may no longer be practiced upon termination of the LICENSE

​

​

or termination of the LICENSE with respect to a particular PRODUCT IN CLASS or LICENSED METHOD that LICENSEE has chosen to abandon, as the case may be, shall be a “RETURNED TECHNOLOGY”.  LICENSEE shall permit YALE and its future licensees of the RETURNED TECHNOLOGY to utilize, reference and otherwise have the benefit of all regulatory approvals of, or clinical trials or other studies conducted by or on behalf of LICENSEE on, and all filings made by or on behalf of LICENSEE with regulatory agencies with respect to, RETURNED TECHNOLOGY.  In addition, at YALE’s request and subject to Section 13.5, LICENSEE shall, at YALE’s sole cost and expense, deliver to YALE copies of records held by or on behalf of LICENSEE that are required by regulatory authorities to be maintained with respect to the sale, storage, handling, shipping and use of the RETURNED TECHNOLOGY, copies of all reimbursement approval files held by LICENSEE, and copies of all documents, data and information held by or on behalf of LICENSEE that are related to clinical trials and other studies by or on behalf of LICENSEE of RETURNED TECHNOLOGIES, all of which are collectively the “RETURNED MATERIALS”.  YALE agrees that, subject to the provisions of Article 8, LICENSEE may retain one copy thereof to the extent LICENSEE is required by law to maintain such copy.  If LICENSEE so returns the RETURNED TECHNOLOGY and the RETURNED MATERIALS within six (6) months after YALE’s request, then in total consideration for the provision of the RETURNED TECHNOLOGY and the RETURNED MATERIALS, YALE shall from time to time pay to LICENSEE [*] percent ([*]%) of all revenue or other financial consideration YALE receives from any new license of the RETURNED TECHNOLOGY and the RETURNED MATERIALS, other than revenue or other consideration that is research support.  YALE shall pay such amounts to LICENSEE within ninety (90) days after YALE receives such revenue. The Parties rights and obligations related to the return of the KLOTHO PATENTS and KLOTHO TECHNOLOGY shall be governed by the KLOTHO RETURNED TECHNOLOGY AGREEMENT.

13.9Upon expiration of the TERM or upon termination of the LICENSE, LICENSEE shall have a non-exclusive, fully paid-up, perpetual license to LICENSED KNOW-HOW to make, have made, use, sell, have sold, import or export any PRODUCT, method, procedure, service or process in the LICENSED TERRITORY.

ARTICLE 14. INDEMNIFICATION; INSURANCE; NO WARRANTIES

14.1LICENSEE shall defend, indemnify and hold harmless YALE, its trustees, directors, officers, employees, and agents and their respective successors, heirs and permitted assigns (the “INDEMNIFIED PERSONS”) against any and all liabilities, claims, demands, damages, judgments, losses and expenses of any nature, including, without limitation, reasonable legal expenses and attorneys’ fees (collectively “CLAIMS”), (1) arising out of any theory of liability (including, without limitation, tort, warranty, or strict liability) or the death, personal injury, or illness of any person or out of damage to any property related in any way to the rights granted under this AGREEMENT; or (2) resulting from the production, manufacture, sale, use, lease, or other disposition or consumption or advertisement of the PRODUCTS IN CLASS or LICENSED METHODS by LICENSEE, its AFFILIATES, SUBLICENSEES or any other transferees; or (3) in connection with any statement, representation or warranty of LICENSEE, its AFFILIATES, SUBLICENSEES or any other transferees with respect to the LICENSED PRODUCTS or LICENSED METHODS.  Each INDEMNIFIED PERSON shall notify LICENSEE promptly after such INDEMNIFIED PERSON learns of a CLAIM or threatened

​

​

CLAIM for which indemnity may be sought under this Section 14.1.  The LICENSEE shall have the right to assume the defense of any legal action for which indemnity may be sought under this Section 14.1.  LICENSEE shall not be responsible for indemnity with regard to any CLAIM that is settled without LICENSEE’s prior written consent.  Notwithstanding any provision of this AGREEMENT to the contrary, no INDEMNIFIED PERSON shall be entitled to indemnity hereunder for any CLAIM arising out of or relating to such INDEMNIFIED PERSON’s participation in any clinical trial involving any PRODUCT IN CLASS or such INDEMNIFIED PERSON’s use of a PRODUCT IN CLASS as a patient.

14.2LICENSEE shall purchase and maintain in effect and shall require its SUBLICENSEES to purchase and maintain in effect a policy of commercial, general liability insurance to protect YALE with respect to events described in Section 14.1.  Such insurance shall:

ARTICLE 17. MISCELLANEOUS

17.1This AGREEMENT shall be binding upon and inure to the benefit of the parties and their respective legal representatives, successors and permitted assigns.

17.2This AGREEMENT constitutes the entire agreement of the parties relating to the LICENSED PATENTS, PRODUCTS IN CLASS and LICENSED METHODS, and all prior representations, agreements and understandings, written or oral, are merged into it and are superseded by this AGREEMENT.  This AGREEMENT supersedes the THIRD AMENDED AND RESTATED LICENSE AGREEMENT in its entirety and, as of the FOURTH AMENDMENT EFFECTIVE DATE, the THIRD AMENDED AND RESTATED LICENSE AGREEMENT shall be of no further force and effect; provided, however, that any obligations to either party accrued by the other party prior to the FOURTH AMENDMENT EFFECTIVE DATE under the THIRD AMENDED AND RESTATED LICENSE AGREEMENT shall remain as such (subject to Section 17.12 below).  For avoidance of doubt and notwithstanding anything stated in this AGREEMENT (or in the  ORIGINAL LICENSE AGREEMENT, FIRST AMENDED AND RESTATED LICENSE AGREEMENT, SECOND AMENDED AND RESTATED LICENSE AGREEMENT or the  THIRD AMENDED AND RESTATED LICENSE AGREEMENT), no payments or other consideration of any kind whatsoever shall be due at any time from LICENSEE or its AFFILIATES or SUBLICENSEES in respect of any PRODUCT or LICENSED METHOD of any kind (whenever LICENSEE or its AFFILIATES or SUBLICENSEES may have commenced work on, worked on, or acquired or in-licensed such PRODUCT or LICENSED METHOD) expect solely and exclusively in respect of the INCLUDED PRODUCT CANDIDATES defined herein.

​

​

17.6This AGREEMENT may not be amended or modified except by written agreement executed by each of the parties.  This AGREEMENT is personal to LICENSEE and shall not be assigned by LICENSEE without the prior written consent of YALE; provided, however, that no such consent of YALE shall be required in case of any assignment of this AGREEMENT by LICENSEE in connection with a merger, consolidation, sale or other transfer of all or substantially all of LICENSEE’s assets or any similar business combination or reorganization so long as the assignee shall expressly assume in writing LICENSEE’s obligations under this AGREEMENT; provided further, however, that in case of any such action or transaction described in the immediately preceding proviso, if the same constitutes a CHANGE OF CONTROL nothing in this Section 17.6 shall remove such transaction from Section 5.4 or 5.7.  Sublicenses shall not be deemed a sale or other transfer of assets by LICENSEE governed by this Section 17.6, but instead shall be governed by Article 4 and, in respect of milestone royalties by Sections 5.5 and 5.8.  Any attempted assignment in contravention of this Section 17.6 shall be null and void and shall constitute a material breach of this AGREEMENT.

17.8The failure of any party hereto to enforce at any time, or for any period of time, any provision of this AGREEMENT shall not be construed as a waiver of either such provision or of the right of such party thereafter to enforce each and every provision of this AGREEMENT.

17.9This AGREEMENT may be executed in any number of counterparts and any party may execute any such counterpart, each of which when executed and delivered shall be deemed to be an original and all of which counterparts taken together shall constitute but one and the same instrument.

17.10Neither YALE nor LICENSEE shall be liable to perform its obligations as required by this AGREEMENT, or shall be in default of its obligations under this AGREEMENT, to the extent such failure to perform or default is caused by any reason beyond such party’s control, including, without limitation, any of the following: labor disturbances or disputes of any kind, accidents, failure of any required governmental approval, civil disorders, acts of aggression, acts of God, energy or other conservation measures, failure of utilities, delays or defaults by common carrier, mechanical breakdowns, material shortages, disease, or similar occurrences.  In case of any such reason beyond a party’s control, the time for performance of such party’s obligations affected thereby shall be extended by the period of the event or circumstance constituting such reason and for a reasonable period of time thereafter.

17.11YALE has provided LICENSEE with the Yale University Patent Policy in effect as of the FOURTH AMENDMENT EFFECTIVE DATE, a copy of which is attached hereto as Appendix E.  As described in the recitals to this AGREEMENT, as of the FOURTH AMENDMENT EFFECTIVE DATE, SCHLESSINGER serves on the  LICENSEE Scientific Advisory Board.  LICENSEE agrees that, for so long as SCHLESSINGER is an employee of YALE, LICENSEE’s rights to any INVENTIONS of SCHLESSINGER created other than in his capacity as a YALE employee shall be subject to the attached Yale University Patent Policy, and that any agreement, past or future, between SCHLESSINGER and LICENSEE regarding

​

​
