In the event that, notwithstanding the fact that X4 has not provided Genzyme such a notice, Genzyme believes that any such Milestone Event has been achieved, it shall so notify X4 in writing and the Parties shall promptly meet and discuss in good faith whether such Milestone Event has been achieved. Any dispute under this Section 6.4.3 regarding whether or not a Milestone Event has been achieved shall be subject to resolution in accordance with Section 13.5.

6.4.5 No Multiple Payments. For purposes of clarity, in the event that any milestone event set forth in Section 6.4.1 and/or Section 6.4.2 is achieved by a Sublicensee, X4 shall be obligated to pay to Genzyme the applicable milestone payment contemplated by Section 6.4.1 or Section 6.4.2, as the case may be, but shall not be obligated to pay Genzyme the Sublicense Percentage of any such milestone payment received by X4 from such Sublicensee.

6.5 Royalties.

6.5.1 Royalty Rates. X4 shall pay Genzyme a royalty on Net Sales of all Licensed Products in the Territory (excluding Net Sales of each Licensed Product in any country in the Territory for which the Royalty Term for such Licensed Product and country has expired) in each Calendar Year (or partial Calendar Year) at the tiered rates set forth in the table below:


Annual Net Sales of all Licensed Products in the Territory	Royalty Rate
[***]		[***]
[***]		[***]
[***]		[***]

6.5.2 Blended Royalty. X4 acknowledges that (a) the Licensed Know-How and the Information included in the Regulatory Documentation licensed by Genzyme to X4 are proprietary and valuable and that without the Licensed Know-How and such Information, X4 may not be able to obtain and maintain Regulatory Approvals with respect to the Licensed Products, (b) such Regulatory Documentation may allow X4 to obtain and maintain Regulatory Exclusivity

with respect to the Licensed Products in the Field in the Territory, and (c) the milestone payments and royalties set forth in Section 6.4 and this Section 6.5, respectively, are, in part, intended to compensate Genzyme for the value of such exclusivity. The Parties agree that the royalty rates set forth in this Section 6.5 reflect an efficient and reasonable blended allocation of the value provided by Genzyme to X4.

6.5.3 Royalty Reduction.

(a) If X4 or any of its Affiliates, is required to pay a Third Party amounts with respect to a Licensed Product in any country under a written agreement under which X4 or its Affiliate obtains a license under or acquires a Patent Controlled by such Third Party that contains a Valid Claim that covers such Licensed Product in such country, X4 may provide written notice to Genzyme setting forth in reasonable detail the identity of such Third Party and such Third Party Patent (which written notice shall include a copy of any such license or acquisition agreement entered into by X4 or its Affiliate as applicable, including its financial terms) and, thereafter, X4 may deduct [***]. Notwithstanding the foregoing, [***].

(b) In the event a Licensed Product is sold in a country and is not covered by a Valid Claim in that country, the tiered royalty rates payable by X4 to Genzyme under Section 6.5.1 shall be reduced by [***] during the applicable Royalty Term with respect to that country.

(c) Generic Products. In the event that one or more Third Parties sell a Generic Product (as defined below) in any country in which a Licensed Product is then being sold by X4, then, (a) during any Calendar Quarter in which sales of the Generic Product by such Third Parties are equal to or greater than [***] (as measured by prescriptions or other similar information available from a Third Party data provider reasonably acceptable to the Parties and applicable to such country) the applicable royalties in effect with respect to such Licensed Product in such country as specified in Section 6.5.1 shall be reduced [***] and (b) during any Calendar Quarter in which sales of the Generic Product by such Third Parties are [***] (as measured by prescriptions or other similar information available from a Third Party data provider reasonably acceptable to the Parties and applicable to such country) the applicable royalties in effect with respect to such Licensed Product in such country as specified in Section 6.5.1 shall be reduced [***]. For purposes of this Section 6.5.3(c), a “Generic Product” means [***].

6.5.4 Payment Dates and Reports. Royalty payments shall be made by X4 [***] after the end of each Calendar Quarter commencing with the Calendar Quarter in which the first day of the first Royalty Term for the first Licensed Product occurs. X4 shall also provide to Genzyme, at the same time each such payment is made, a report showing: (a) the Invoiced Sales of Licensed Products by country (in the local currency) in the Territory and the Net Sales of Licensed Products by country (in Dollars); (b) the basis for any deductions from Invoiced Sales to determine Net Sales; (c) the applicable royalty rates for the Licensed Products; (d) the exchange rates used in calculating any of the foregoing; and (e) a calculation of the amount of royalty due to Genzyme.

6.6 Sublicense Revenue. X4 shall pay to Genzyme the applicable Sublicense Percentage of any Sublicense Revenue paid to X4 or any of its Affiliates in connection with any Sublicense.

6.7 Mode of Payment; Currency Conversion.

(a) All payments to Genzyme under this Agreement shall be made by electronic funds transfer of Dollars in the requisite amount to such bank account as Genzyme may from time to time designate by written notice to X4.

(b) If any currency conversion shall be required in connection with any payment hereunder, such conversion shall be made by using the arithmetic mean of the exchange rates for the purchase of Dollars as published in The Wall Street Journal, Eastern Edition, on the last Business Day of each month in the Calendar Quarter to which such payments relate.

6.8 Taxes. Genzyme alone shall be responsible for paying any and all income taxes (other than withholding taxes required by Applicable Law to be paid by X4) levied on account of, or measured in whole or in part by reference to, any milestones and other amounts payable by X4 to Genzyme pursuant to this Agreement (“Payments”) it receives. X4 shall deduct or withhold from the Payments any taxes that it is required by Applicable Law to deduct or withhold. Notwithstanding the foregoing, if Genzyme or any of its Affiliates is entitled under any applicable tax treaty to a reduction of rate of, or the elimination of, applicable withholding tax, it may deliver to X4 or the appropriate governmental authority (with the assistance of X4) the prescribed forms (including the US Tax Residency Form 6166 or IRS Form W-8BEN-E) necessary to reduce the applicable rate of withholding or to relieve X4 of its obligation to withhold tax, and X4 shall apply the reduced rate of withholding, or dispense with withholding, as the case may be; provided that X4 has received from Genzyme delivery of all applicable forms (and, if necessary, its receipt of appropriate governmental authorization) at least fifteen (15) days prior to the time that the Payments are due. X4 shall notify Genzyme if X4 intends to withhold at least thirty (30) days prior to the time the Payments are due. If, in accordance with the foregoing, X4 withholds any amount, it shall pay to Genzyme the balance when due, make timely payment to the proper taxing authority of the withheld amount and send to Genzyme proof of such payment within fifteen (15) days following such payment.

6.9 Interest on Late Payments. If any Payment due to Genzyme under this Agreement is not paid in when due, then X4 shall pay interest on the unpaid amount and on any unpaid accrued interest (before and after any judgment) at an annual rate (but with interest accruing on a daily basis) of [***], or the maximum rate permitted by Applicable Laws, whichever is less, such interest to run from the date upon which payment of such amount became due until payment thereof in full together with such accrued interest.

6.10 Financial Records. X4 and its Affiliates shall, and X4 shall include in each of its Sublicense agreements an obligation of such Sublicensees to, keep complete and accurate books and records that are necessary to verify the milestone and royalty payments owed under Section 6.4 and Section 6.5, including books and records of Invoiced Sales

(including any deductions therefrom) and Net Sales of Licensed Products in the Territory. X4 and its Affiliates shall, and X4 shall include in each of its Sublicense agreements an obligation of such Sublicensee to, retain such books and records, until the later of [***], or for such longer period as may be required by Applicable Law.

6.11 Audit. At the request of Genzyme, X4 and its Affiliates shall, and X4 shall include in each of its Sublicense agreements an obligation of such Sublicensee to, permit an independent certified public accountant retained by Genzyme, at reasonable times and upon reasonable notice, to audit the books and records maintained pursuant to Section 6.10. In no event shall such independent certified public accountant disclose to Genzyme any information other than its findings regarding the accuracy of the reports and payments made by X4 under this Article 6. Such audits may not (a) be conducted for any Calendar Quarter [***], (b) be conducted [***] (unless a previous audit during such [***] revealed an underpayment with respect to such period or X4 restates or revises such books and records for such [***]) or (c) be repeated for any Calendar Quarter. Except as provided below, the cost of any audit shall be borne by Genzyme, unless the audit reveals [***], in which case X4 shall bear the cost of the audit. Unless disputed pursuant to Section 6.12, (a) if such audit concludes that additional payments were due and payable by X4, X4 shall pay the additional amounts, with interest from the date originally due as provided in Section 6.9 within thirty (30) days after the date on which such audit is completed and the conclusions thereof are notified to the Parties and (b) if such audit concludes that X4 overpaid Genzyme, [***]. Notwithstanding the foregoing, to the extent that X4 does not have the right to grant Genzyme the right to audit the records of any of its Sublicensees hereunder, X4 shall obtain for itself such right and, at Genzyme’s request in accordance with the third sentence of this Section 6.11, X4 shall exercise such audit right with respect to such Sublicensees, using an independent certified public account reasonably acceptable to Genzyme, and shall provide the results of such audit to Genzyme.

6.12 Audit Dispute. In the event of a dispute over the results of any audit conducted pursuant to Section 6.11, Genzyme and X4 shall work in good faith to resolve such dispute. If the Parties are unable to reach a mutually acceptable resolution of any such dispute [***], the dispute shall be submitted for arbitration to a certified public accounting firm selected by each Party’s certified public accountants or to such other Person as the Parties shall mutually agree (the “Accountant”) or failing such agreement, as the Chairman of the International Chamber of Commerce (or such other body as the Parties may mutually agree), may nominate. The decision of the Accountant shall be final and the costs of such arbitration as well as the initial audit shall be borne between the Parties in such manner as the Accountant shall determine.

6.13 Confidentiality. Genzyme shall treat all information subject to review under this ARTICLE 6 in accordance with the confidentiality provisions of ARTICLE 9 and Genzyme shall cause the independent public accountant retained by Genzyme pursuant to Section 6.11 or the Accountant, as applicable, to enter into a reasonably acceptable confidentiality agreement that includes an obligation to retain all such financial information in confidence and to disclose to Genzyme solely its findings regarding the accuracy of the reports and payments made by X4 hereunder, and not any other such financial information.

ARTICLE 11

INDEMNITY

11.1 Indemnification of Genzyme. X4 shall indemnify Genzyme, its Affiliates and its and their respective directors, officers, employees and agents (collectively, “Genzyme Indemnitees”), and defend and save each of them harmless, from and against any and all losses, damages, liabilities, costs and expenses (including reasonable attorneys’ fees and expenses) (collectively, “Losses”) in connection with any and all suits, investigations, claims or demands of Third Parties (collectively, “Third Party Claims”) arising from or occurring as a result of: (a) the breach by X4 of any representation, warranty, covenant, obligation or agreement made or undertaken by X4 under this Agreement, (b) the gross negligence or willful misconduct on the part of any X4 Indemnitee or (c) the Exploitation of any Licensed Compounds or Licensed Products in the Field by or on behalf of X4, its Sublicensees or any of its or their respective Affiliates; provided that, with respect to any Third Party Claim for which X4 has an obligation to any Genzyme Indemnitee pursuant to this Section 11.1 and Genzyme has an obligation to any X4 Indemnitee pursuant to Section 11.2, each Party shall indemnify each of the Genzyme Indemnitees or the X4 Indemnitees, as applicable, for its Losses to the extent of its responsibility, relative to the other Party. The foregoing indemnification obligation shall not apply to the extent that the Genzyme Indemnitees fail to comply with the indemnification procedures set forth in Sections 11.3 and 11.4 and X4’s defense of the relevant Claims is prejudiced by such failure.

11.2 Indemnification of X4. Genzyme shall indemnify X4, its Affiliates and its and their respective directors, officers, employees and agents (collectively, “X4 Indemnitees”), and defend and save each of them harmless, from and against any and all Losses in connection with any and all Third Party Claims arising from or occurring as a result of: (a) the breach by Genzyme of any representation, warranty, covenant, obligation or agreement made or undertaken by Genzyme under this Agreement or (b) the gross negligence or willful misconduct on the part of any Genzyme Indemnitee; provided that, with respect to any Third Party Claim for which Genzyme has an obligation to any X4 Indemnitee pursuant to this Section 11.2 and X4 has an obligation to any Genzyme Indemnitee pursuant to Section 11.1, each Party shall indemnify each of the Genzyme Indemnitees or the X4 Indemnitees, as applicable, for its Losses to the extent of its responsibility, relative to the other Party. The foregoing indemnification obligation shall not apply to the extent that the X4 Indemnitees fail to comply with the indemnification procedures set forth in Sections 11.3 and 11.4 and Genzyme’s defense of the relevant Claims is prejudiced by such failure.

11.3 Notice of Claim. All indemnification claims in respect of a Genzyme Indemnitee or a X4 Indemnitee shall be made solely by Genzyme or X4, as applicable (each of Genzyme or X4 in such capacity, the “Indemnified Party”). The Indemnified Party shall give the Indemnifying Party prompt written notice (an “Indemnification Claim Notice”) of any Losses or discovery of fact upon which such Indemnified Party intends to base a request

for indemnification under Section 11.1 or Section 11.2, but in no event shall the Indemnifying Party be liable for any Losses that result from any delay in providing such notice. Each Indemnification Claim Notice must contain a description of the claim and the nature and amount of such Loss (to the extent that the nature and amount of such Loss is known at such time). The Indemnified Party shall furnish promptly to the Indemnifying Party copies of all papers and official documents received in respect of any Losses and Third Party Claims.

11.4 Control of Defense.

11.4.1 Control of Defense. At its option, the Indemnifying Party may assume the defense of any Third Party Claim by giving written notice to the Indemnified Party [***]. The assumption of the defense of a Third Party Claim by the Indemnifying Party shall not be construed as an acknowledgment that the Indemnifying Party is liable to indemnify any Genzyme Indemnitee or X4 Indemnitee, as applicable, in respect of the Third Party Claim, nor shall it constitute a waiver by the Indemnifying Party of any defenses it may assert against a Genzyme Indemnitee’s or a X4 Indemnitee’s, as applicable, claim for indemnification. Upon assuming the defense of a Third Party Claim, the Indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the Indemnifying Party. In the event the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party shall immediately deliver to the Indemnifying Party all original notices and documents (including court papers) received by any Genzyme Indemnitee or X4 Indemnitee, as applicable, in connection with the Third Party Claim. If the Indemnifying Party assumes the defense of a Third Party Claim, except as provided in Section 11.4.2, the Indemnifying Party shall not be liable to the Indemnified Party for any legal expenses subsequently incurred by such Indemnified Party or any Genzyme Indemnitee or X4 Indemnitee, as applicable, in connection with the analysis, defense or settlement of such Third Party Claim. In the event that it is ultimately determined that the Indemnifying Party is not obligated to indemnify, defend or hold harmless a Genzyme Indemnitee or X4 Indemnitee, as applicable, from and against a Third Party Claim, the Indemnified Party shall reimburse the Indemnifying Party for any and all costs and expenses (including attorneys’ fees and costs of suit) incurred by the Indemnifying Party in its defense of such Third Party Claim.

11.4.2 Right to Participate in Defense. Without limiting Section 11.4.1, any Indemnified Party shall be entitled to participate in, but not control, the defense of a Third Party Claim and to employ counsel of its choice for such purpose; provided that such employment shall be at the Indemnified Party’s own expense unless (a) the employment thereof has been specifically authorized by the Indemnifying Party in writing, (b) the Indemnifying Party has failed to assume the defense and employ counsel in accordance with Section 11.4.1 (in which case the Indemnified Party shall control the defense) or (c) the interests of the Indemnified Party and any Genzyme Indemnitee or X4 Indemnitee, as applicable, on the one hand, and the Indemnifying Party, on the other hand, with respect to such Third Party Claim are sufficiently adverse to prohibit the representation by the same counsel of all such Persons under Applicable Law, ethical rules or equitable principles.

11.4.3 Settlement. With respect to any Third Party Claims relating solely to the payment of money damages in connection with a Third Party Claim that shall not result in any

Genzyme Indemnitee or X4 Indemnitee, as applicable, becoming subject to injunctive or other relief or otherwise adversely affecting the business, rights, or interests of any Genzyme Indemnitee or X4 Indemnitee, as applicable, in any manner and as to which the Indemnifying Party shall have acknowledged in writing the obligation to indemnify such Genzyme Indemnitee or X4 Indemnitee, as applicable, hereunder, the Indemnifying Party shall have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Third Party Claim, on such terms as the Indemnifying Party, in its sole discretion, shall deem appropriate. With respect to all other Third Party Claims, where the Indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 11.4.1, the Indemnifying Party shall have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Third Party Claim, provided that it obtains the prior written consent of the Indemnified Party (such consent not to be unreasonably conditioned, withheld or delayed). The Indemnifying Party shall not be liable for any settlement or other disposition of a Third Party Claim by a Genzyme Indemnitee or a X4 Indemnitee that is reached without the prior written consent of the Indemnifying Party. So long as the Indemnifying Party is actively defending or prosecuting any Third Party Claim, the Indemnified Party shall not, and the Indemnified Party shall ensure that each Genzyme Indemnitee or X4 Indemnitee, as applicable, does not, admit any liability with respect to or settle, compromise or discharge, such Third Party Claim without the prior written consent of the Indemnifying Party, such consent not to be unreasonably conditioned, withheld or delayed. If the Indemnifying Party does not assume and conduct the defense of a Third Party Claim [***], the Indemnified Party may consent to the entry of any judgment or enter into any settlement with respect to such Third Party Claim in any manner the Indemnified Party may deem reasonably appropriate. For clarity, the assumption of the defense of any Third Party Claim by the Indemnified Party in accordance with the preceding sentence shall in no event relieve the Indemnifying Party from its obligations to indemnify and hold harmless the Indemnified Party from all Losses arising from such Third Party Claim.

11.4.4 Cooperation. Regardless of whether the Indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party shall, and shall cause each Genzyme Indemnitee or X4 Indemnitee, as applicable, to, cooperate in the defense or prosecution thereof and shall furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such cooperation shall include access during normal business hours afforded to the Indemnifying Party to, and reasonable retention by the Indemnified Party and any Genzyme Indemnitee or X4 Indemnitee, as applicable, of, records and information that are reasonably relevant to such Third Party Claim, and making all Genzyme Indemnitees or X4 Indemnitees, as applicable, and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder; provided that neither Party shall be required to disclose legally privileged information unless and until procedures reasonably acceptable to such Party are in place to protect such privilege, and the Indemnifying Party shall reimburse the Indemnified Party for all its reasonable costs and expenses in connection therewith.

11.4.5 Expenses. Except as provided above, the costs and expenses, including fees and disbursements of counsel, incurred by the Indemnified Party in connection with any Third Party Claim shall be reimbursed on a Calendar Quarter basis by the Indemnifying Party, without

prejudice to the Indemnifying Party’s right to contest any Genzyme Indemnitee’s or X4 Indemnitee’s, as applicable, right to indemnification and subject to refund in the event the Indemnifying Party is ultimately held not to be obligated to indemnify a Genzyme Indemnitee or X4 Indemnitee, as applicable.

11.5 Limitation on Damages and Liability. [***], NEITHER PARTY NOR ANY OF THEIR RESPECTIVE AFFILIATES SHALL BE LIABLE FOR SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES, OR FOR LOST PROFITS, WHETHER IN CONTRACT, WARRANTY, NEGLIGENCE, TORT, STRICT LIABILITY OR OTHERWISE, ARISING OUT OF (a) THE DEVELOPMENT, MANUFACTURE, USE OR SALE OF THE LICENSED PRODUCTS UNDER THIS AGREEMENT, (b) THE USE OF OR REFERENCE TO THE LICENSED PATENTS, LICENSED KNOW-HOW OR REGULATORY DOCUMENTATION OR (c) ANY BREACH OF OR FAILURE TO PERFORM ANY OF THE PROVISIONS OF THIS AGREEMENT.

11.6 Insurance. X4 shall, and shall cause its Sublicensees and its and their respective Affiliates to maintain (a) no later than thirty days prior to the anticipated date of First Commercial Sale of a Licensed Product, (i) commercial general liability insurance covering bodily injury and property damage of not less than [***] per occurrence and in the aggregate, and (ii) clinical trials liability insurance coverage with minimum indemnity limits of [***] per occurrence and in the aggregate, and (b) following the First Commercial Sale of a Licensed Product, and thereafter during any period in which X4 has indemnification obligations to Genzyme, (i) commercial general liability insurance covering bodily injury and property damage of not less than [***] per occurrence and in the aggregate, and (ii) products liability/completed operations and clinical trials liability insurance coverage with minimum indemnity limits of [***] per occurrence and in the aggregate. Such policies shall be provided by insurance carrier(s) reasonably acceptable to Genzyme. [***]. If such policies are written on a claims made basis, they shall remain in effect for a minimum period of [***] and shall not be cancelled or subject to a reduction of coverage without the prior written authorization of Genzyme. Upon Genzyme’s written request, X4 shall provide Genzyme with certificate(s) of insurance or certified copies of X4’s insurance policies to evidence the purchase and/or maintenance of such policies. Maintenance of such insurance coverage shall not relieve X4 of any responsibility under this Agreement for damages in excess of insurance limits or otherwise.

ARTICLE 12

TERM AND TERMINATION

12.1 Termination upon Failure to Close the X4 First Financing. [***]. In the event that X4 does not consummate [***], then the Financing Exclusivity Period shall automatically be extended by [***]. In the event that X4 does not [***], as so extended, and the Parties have not otherwise agreed in writing to further extend such period, this Agreement shall immediately terminate and Genzyme shall have no further obligations to X4 with respect to the Licensed Patent and Licensed Know-How and shall be free to negotiate and enter into any agreement with a Third Party concerning the Licensed Patents or the Licensed Know How.

12.2 Term. This Agreement shall commence on the Effective Date and shall, unless earlier terminated in accordance with this ARTICLE 12, continue (a) with respect to each Licensed Product in each country in the Territory, until the expiration of the Royalty Term for such Licensed Product in such country and (b) with respect to this Agreement in its entirety, until the expiration of the last-to-expire Royalty Term for any Licensed Product in the Territory (such period, the “Term”).

12.3 Termination of this Agreement for Material Breach. In the event that either Party materially breaches this Agreement (such Party, the “Breaching Party”), in addition to any other right and remedy the other Party (the “Complaining Party”) may have, the Complaining Party may terminate this Agreement, in its entirety upon ninety (90) days’ prior written notice (the “Termination Notice Period”) to the Breaching Party, specifying the material breach and its claim of right to terminate, provided that the termination shall not become effective at the end of the Termination Notice Period if the Breaching Party cures the material breach complained of during the Termination Notice Period The Breaching Party may dispute any alleged breach by written notice to the Complaining Party within such ninety-(90) day period, in which case the Complaining Party shall not have the right to terminate this Agreement pursuant to this Section 12.3 unless and until it has been mutually agreed pursuant to Section 13.5 or determined in accordance with Section 13.5 below that this Agreement was materially breached by the Breaching Party, and the Breaching Party fails to comply with its obligations hereunder within ninety (90) days after such mutual agreement or determination, as applicable. Notwithstanding the foregoing, it is understood and agreed that termination of this Agreement pursuant to this Section 12.3 shall in no way limit either Party’s right to seek all remedies available by law and in equity.

12.4 Unilateral Termination Rights.

12.4.1 In the event that X4 or any of its Affiliates anywhere in the Territory, institutes, prosecutes or otherwise participates in (or in any way aids any Third Party in instituting, prosecuting or participating in), at law or in equity or before any administrative or regulatory body, including the U.S. Patent and Trademark Office or its foreign counterparts, any claim, demand, action or cause of action for declaratory relief, damages or any other remedy or for an enjoinment, injunction or any other equitable remedy, including any interference, reexamination, post grant review, opposition or any similar proceeding, alleging that any claim in a Licensed Patent is invalid, unenforceable or otherwise not patentable (a “Patent Challenge”) (except as required under a court order or subpoena), Genzyme may terminate this Agreement immediately upon written notice to X4. In the event that a Sublicensee of X4 or an Affiliate thereof anywhere in the Territory institutes, prosecutes or otherwise participates in (or in any way aids any Third Party in instituting, prosecuting or participating in) a Patent Challenge (except as required under a court order or subpoena), then Genzyme may send a written demand to X4 to terminate such sublicense in the event such Sublicensee fails to withdraw such Patent Challenge or such Patent Challenge is otherwise not dismissed [***]. If such Sublicensee fails to withdraw such Patent Challenge or such Patent Challenge is not dismissed [***], and thereafter, X4 shall terminate such Sublicense [***]. Notwithstanding the foregoing, Genzyme shall not have any termination rights pursuant to

this Section 12.4.1 on account of any Patent Challenge that is either (i) a legal or administrative challenge asserted as a counterclaim in an action initiated by or under the authority of Genzyme against X4, its Sublicensees or their respective Affiliates, or (ii) a declaratory action proceeding brought against Genzyme with respect to the validity, patentability or enforceability of any Licensed Patent as a result of Genzyme threatening to bring any action against X4, its Sublicensees, or their respective Affiliates.

12.4.2 X4 may terminate this Agreement in its entirety immediately upon notice to Genzyme for a Material Safety Issue. “Material Safety Issue” shall mean the reasonable belief of X4 or any of its Affiliates’ or Sublicensees’ based upon additional information that becomes available or an analysis of the existing information at any time, that the medical risk/benefit profile of the Licensed Compound or a Licensed Product is so unfavorable that it would be incompatible with the welfare of patients to Develop or Commercialize such Licensed Compound or Licensed Product or to continue to Develop or Commercialize it. In the event of a dispute as to whether a Material Safety Issue exists, the Parties shall resolve the dispute in accordance with Section 13.5, unless the Data Safety Monitoring Board or any institutional Review Board or any Regulatory Authority has recommended to X4 or Genzyme, or their Sublicensees or Affiliates, to terminate an ongoing Clinical Study of the Licensed Compound or Licensed Product or has halted or placed any such ongoing Clinical Study on hold, or a Regulatory Authority has withdrawn or requested that X4 withdraw any applicable Regulatory Approval for a Licensed Product, all of which foregoing circumstances shall be deemed conclusive evidence of the existence of a Material Safety Issue giving rise to X4’s right to terminate under this Section 12.4.2.

12.5 Termination Upon Insolvency. Either Party may terminate this Agreement if, at any time, the other Party (a) files in any court or agency pursuant to any statute or regulation of any state, country or jurisdiction, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of such other Party or of its assets, (b) is declared insolvent or bankrupt by a court of competent jurisdiction, (c) is served with an involuntary petition against it, filed in any insolvency proceeding that is not dismissed within ninety (90) days after the filing thereof, (d) proposes or is placed in a process of complete liquidation, or (e) makes an assignment of substantially all of its assets for the benefit of its creditors.

12.6 Rights in Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by X4 or Genzyme are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of right to “intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code. The Parties agree that the Parties, as licensees of such rights under this Agreement, shall retain and may fully exercise all of their rights and elections under the U.S. Bankruptcy Code.

12.7 Consequences of Termination.

12.7.1 In the event of a termination of this Agreement for any reason, any Sublicense agreement entered into by X4 as of the effective date of termination shall remain in full force and effect; provided, that, (a) the applicable Sublicensee is not then in breach of its Sublicense agreement with X4 and agrees to be bound to Genzyme as a direct licensee under the terms and conditions of the Sublicense agreement and (b) the Sublicensee promptly enters into appropriate agreements or amendments to the Sublicense agreement to substitute Genzyme for X4 as the licensor thereunder.

12.7.2 In the event of a termination of this Agreement for any reason other than as provided in Section 12.7.4, all rights and licenses granted by Genzyme hereunder shall immediately terminate; provided, that, if such termination occurs after the First Commercial Sale of a Licensed Product hereunder, X4 and its Sublicensees and Affiliates shall have the right to continue selling any or all Licensed Product remaining in their inventory for [***], provided that the sale of such remaining inventory will be subject to the royalty obligations set forth in Section 6.5.

12.7.3 Upon termination of this Agreement by Genzyme pursuant to Section 12.3 or 12.4.1, X4 shall promptly, to the extent requested by Genzyme:

(a) where permitted by Applicable Law, assign to Genzyme all of its right, title and interest in and to, and transfer possession to Genzyme of, all Regulatory Documentation (including, for clarity, Regulatory Approvals) then in its name applicable to any Licensed Product in the Territory;

(b) notify the applicable Regulatory Authorities and take any other action reasonably necessary to effect the transfer set forth in clause (a) above;

(c) grant Genzyme [***], under all Regulatory Documentation (including any Regulatory Approvals) then owned or Controlled by X4 then in its name that are not assigned to Genzyme pursuant to clause (a) above that are necessary or useful for Genzyme or any of its Affiliates to Exploit any Licensed Compound or Licensed Product in the Field in the Territory and any improvement to any of the foregoing, as such Regulatory Documentation exists as of the effective date of such termination of this Agreement and X4 shall continue to maintain such Regulatory Documentation (including any Regulatory Approvals) unless and until Genzyme notifies X4 that such maintenance is no longer required;

(d) to the extent requested in writing by Genzyme, grant Genzyme [***], under the X4 Know-How and the X4 Patents, to Exploit Licensed Products in the Field and, following any such termination, the provisions of ARTICLE 7 that apply to Licensed Patents shall survive with respect to such X4 Patents with Genzyme having, with respect to such X4 Patents, the rights and obligations that X4 has with respect to the Licensed Patents; provided, that, the survival of the licenses granted to Genzyme pursuant to this Section 12.7.3(d) shall be subject to [***]. For purposes of this Section 12.7.3(d), the term “X4 Licensed Product” shall mean any Licensed Product that is covered by a Valid Claim of any X4 Patents and for uses or incorporates any X4 Know-How and “Applicable Post-Termination Percentage” means, with respect to each X4 Licensed Product described in this Section 12.7.3(d), (1) if the effective date of termination is [***] with respect to any such X4 Licensed Product in any country in the Territory, [***], (2) if the effective date of termination is [***] with respect to any such X4 Licensed Product in any country in the Territory but [***] with respect to such X4 Licensed Product in any country in the Territory, [***], (3) if the effective date of termination is on or after [***] with respect to any such X4 Licensed Product in any country in the Territory but prior to [***] with respect to any such X4 Licensed Product in any country in the Territory, [***], and (z) if the effective date of termination is [***] with respect to any such X4 Licensed Product in any country in the Territory, [***].

(e) unless expressly prohibited by any Regulatory Authority, transfer control to Genzyme of all Clinical Studies of each Licensed Product being conducted as of the effective date of termination and continue to conduct such Clinical Studies, at Genzyme’s cost and expense, [***] to enable such transfer to be completed without interruption of any such Clinical Study; provided, that, Genzyme shall not have any obligation to continue any Clinical Study unless required by Applicable Law and (ii) with respect to each Clinical Study for which such transfer is expressly prohibited by the applicable Regulatory Authority, X4 shall continue to conduct such Clinical Study [***] at Genzyme’s reasonable cost and expense.

(f) assign (or cause its Affiliates to assign) to Genzyme all Licensed Product Agreements, unless, with respect to any such Licensed Product Agreement, such Licensed Product Agreement expressly prohibits such assignment or relates to products in addition to the Licensed Product, in which case X4 shall cooperate with Genzyme in all reasonable respects to secure the consent of the applicable Third Party to such assignment and if any such consent cannot be obtained with respect to a Licensed Product Agreement, X4 shall use Commercially Reasonable Efforts at Genzyme’s cost and expense to try to obtain for Genzyme substantially all of the practical benefit and burden under such Licensed Product Agreement, including by (i) pursuing appropriate and reasonable alternative arrangements (such as splitting Licensed Product Agreements non exclusively related to Licensed Products) on terms mutually agreeable to Genzyme and X4 and (ii) subject to the consent and control of Genzyme, pursuing the enforcement, at Genzyme’s cost and expense and for the account of Genzyme, of any and all rights of X4 against the other party thereto arising out of the breach or cancellation thereof by such other party or otherwise; [***];

(g) provide Genzyme with copies of all reports and data generated or obtained by X4 or any of its Affiliates that relate to any Licensed Product that have not previously been provided to Genzyme;

(h) where permitted by Applicable Laws, assign to Genzyme all right, title, and interest of X4 in each Product Trademark; and

(i) sell to Genzyme some or all of the inventory of Licensed Compound and/or Licensed Product in possession of X4 and Affiliates as of the termination date, at a price equal to [***].

Except in the event of termination of this Agreement by Genzyme pursuant to Section 12.3, Genzyme shall reimburse X4 for all reasonable, documented out-of-pocket expenses incurred by X4 in performing its obligations under Section 12.7.3(a) to (h).

12.7.4 Upon termination by X4 pursuant to Section 12.3 or 12.5, then: (a) the licenses granted by Genzyme to X4 pursuant to Section 2.1 hereof shall survive on a country-by-country and Licensed Product-by-Licensed Product basis until the expiration of the Royalty Term

for each such Licensed Product in each such country, subject to [***]; and (b) each Party shall promptly return or destroy all Confidential Information of the other Party; provided, further that, each Party may retain, subject to ARTICLE 7 hereof, (i) one (1) copy of the Confidential Information of the other Party in its archives for the purpose of establishing the contents thereof and ensuring compliance with its obligations hereunder and (ii) any Confidential Information of the other Party contained in its laboratory notebooks or databases; and X4 may retain and use Genzyme’s Confidential Information solely in connection with the exercise of its rights set forth in clause (a) of this Section 12.7.4.

12.7.5 Without limiting Genzyme’s rights under other provisions of this ARTICLE 12, in the event of any termination by Genzyme pursuant to Section 12.3 or by X4 pursuant to 12.4.2, X4 shall, at the request and expense of Genzyme, use Commercially Reasonable Efforts to provide Genzyme with such assistance, [***], as is reasonably necessary to effectuate a smooth and orderly transition of any Development, Manufacture and Commercialization activities to Genzyme or its designee so as to minimize any disruption of such activities. Further, upon Genzyme’s request and expense, in the event of any termination by Genzyme pursuant to Section 12.3 or by X4 pursuant to 12.4.2 after the First Commercial Sale of a Licensed Product hereunder, X4 shall provide such technical assistance, [***], as may reasonably be requested to transfer all Manufacturing technology that is or had been used by or on behalf of X4 and its Affiliates in connection with the Manufacture of any Licensed Compound or Licensed Product.

12.8 Accrued Rights; Surviving Obligations.

MISCELLANEOUS

13.1 Force Majeure. Neither Party shall be held liable or responsible to the other Party or be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement (other than an obligation to make payments) when such failure or delay is caused by or results from events beyond the

reasonable control of the non-performing Party, including fires, floods, earthquakes, embargoes, shortages, epidemics, quarantines, war, acts of war (whether war be declared or not), terrorist acts, insurrections, riots, civil commotion, strikes, lockouts or other labor disturbances (whether involving the workforce of the non-performing Party or of any other Person), acts of God or acts, omissions or delays in acting by any governmental authority (each, a “Force Majeure Event”). The non-performing Party shall notify the other Party of a Force Majeure Event [***] by giving written notice to the other Party stating the nature of such Force Majeure Event, its anticipated duration, and any action being taken to avoid or minimize its effect. The suspension of performance shall be of no greater scope and no longer duration than is necessary and the non-performing Party shall use commercially reasonable efforts to remedy its inability to perform. In the event that such suspension of performance [***] and in the absence of such Force Majeure Event such suspension of performance would be a material breach of this Agreement, such other Party shall have the right to terminate this Agreement pursuant to Section 12.3.

13.2 Export Control. This Agreement is made subject to any restrictions concerning the export of products or technical information from the United States or other countries that may be imposed on or related to the Parties from time to time. Each Party agrees that it will not export, directly or indirectly, any technical information acquired from the other Party under this Agreement or any products using such technical information to a location or in a manner that at the time of export requires an export license or other governmental approval, without first obtaining the written consent to do so from the appropriate agency or other governmental entity in accordance with Applicable Law.

13.3 Assignment. Neither Party shall sell, transfer, assign, delegate, pledge or otherwise dispose of, whether voluntarily, involuntarily, by operation of law or otherwise, this Agreement or any of its rights or duties hereunder without the prior written consent of the other Party; provided that (a) Genzyme may, without such consent, assign this Agreement and its rights and obligations hereunder to an Affiliate, to the purchaser of the Licensed Patents or Licensed Know-How or to its successor entity or acquirer in the event of a merger, consolidation or change in control of Genzyme and (b) X4 may without such consent, [***], assign this Agreement and its rights and obligations hereunder in connection with a Change of Control; provided, further, that in either case ((a) or (b)), the assignee or transferee shall assume all obligations of its assignor or transferor under this Agreement and such assignor or transferor shall remain responsible to the other Party for the performance by such assignee or transferee of the rights and obligations of the assigning Party hereunder. Any attempted assignment or delegation in violation of the preceding sentence shall be void and of no effect. All validly assigned and delegated rights and obligations of the Parties hereunder shall be binding upon and inure to the benefit of and be enforceable by and against the successors and permitted assigns of Genzyme or X4, as the case may be. [***].

13.4 Severability. To the fullest extent permitted by Applicable Law, the Parties waive any provision of law that would render any provision in this Agreement invalid, illegal, or unenforceable in any respect. If any provision of this Agreement is held to be invalid, illegal, or unenforceable, in any respect, then such provision will be given no effect by the Parties and shall not form part of this Agreement. To the fullest extent permitted by

Applicable Law and if the rights or obligations of either Party will not be materially and adversely affected, all other provisions of this Agreement shall remain in full force and effect, and the Parties shall use their best efforts to negotiate a provision in replacement of the provision held invalid, illegal, or unenforceable that is consistent with Applicable Law and achieves, as nearly as possible, the original intention of the Parties.

13.5 Dispute Resolution. If a dispute arises between the Parties in connection with the interpretation, validity or performance of this Agreement or any document or instrument delivered in connection herewith, then either Party shall have the right to refer such dispute to the Executive Officers for attempted resolution by good faith negotiations during a period of [***]. Any final decision mutually agreed to by the Executive Officers shall be conclusive and binding on the Parties. If such Executive Officers are unable to resolve such dispute within such [***] period, either Party shall be free to institute litigation in accordance with Section 13.6 and seek such remedies as may be available. Notwithstanding anything in this Agreement to the contrary, either Party shall be entitled to institute litigation in accordance with Section 13.6 immediately if litigation is necessary to prevent irreparable harm to that Party.

Patents and Intellectual Property Rights

8.1

Patent Prosecution. LICENSEE shall have the first right, but not the obligation, to prepare, file, prosecute (including to seek extensions of), maintain and defend all pending patent applications and patents comprising Licensed Patents (including any inter partes and opposition proceedings relative to Licensed Patents). LICENSOR shall reasonably cooperate with LICENSEE in the filing, prosecution, maintenance and defense of the Licensed Patents. Such cooperation includes promptly executing all documents, or requiring inventors, subcontractors, employees and consultants and agents of LICENSOR and its Affiliates to execute all documents, and joining as a party in any proceedings, as reasonable and appropriate so as to enable the filing, prosecution, maintenance and defense of any Licensed Patents in any country. If LICENSEE elects not to file, prosecute, maintain and defend any of the Licensed Patents, LICENSOR may (but shall not be obligated to), upon notice to LICENSEE, undertake such filing, prosecution, maintenance and defense of such Licensed Patents at LICENSOR’s sole cost and expense, subject to LICENSEE’s prior written consent, not to be unreasonably withheld. LICENSEE may prepare, file, prosecute, maintain and defend all Licensed Patents using counsel of its choice. In the event that LICENSEE changes counsel for any reason, LICENSEE shall replace such counsel with new counsel of its choice that is reasonably acceptable to LICENSOR, provided, however, that if LICENSOR rejects the choice of new counsel by LICENSEE [***], then LICENSEE shall be free, in its sole discretion,

GU Reference: 2016-058

to choose an attorney of its choice. LICENSEE shall instruct counsel to promptly provide LICENSOR with copies of all relevant documentation so that LICENSOR may be currently and promptly informed and appraised of the prosecution of Licensed Patents, but in no case [***] in advance of any deadline for filing a response, and so that LICENSOR may comment upon such documentation sufficiently in advance of any final deadline for filing a response, provided, however, that if LICENSOR has not commented upon such documentation [***] to the final deadline for filing a response, LICENSEE shall be free to respond appropriately without waiting for LICENSOR’s comments, if any. LICENSEE shall, in good faith, consider all reasonable comments provided by LICENSOR. LICENSEE shall not finally and irrevocably cancel all Valid Claims in a Licensed Patent without LICENSOR’s prior written consent, not to be unreasonably withheld, it being understood that abandonment of a Licensed Patent shall not be deemed a cancellation of all Valid Claims in such Licensed Patent if a continuation or similar application claiming priority (directly or indirectly) to such Licensed Patent is filed and which continuation or other application includes one or more Valid Claims of the abandoned Licensed Patent. Both parties hereto shall keep this documentation in confidence in accordance with the provisions of Article 12 herein.

8.2

Costs. Except as provided in Section 8.1, all costs, including without limitation attorneys’ fees, incurred by LICENSEE for preparing, filing, prosecuting, copying LICENSOR, and maintaining and defending the Licensed Patents, whether incurred prior to or after the Effective Date, shall be borne by LICENSEE. The costs of all oppositions initiated or defended by LICENSEE shall be considered prosecution expenses and also shall be borne by LICENSEE.

8.3	Duration of Obligation. LICENSEE’s obligation to pay costs as set forth in this Article 8 shall continue until [***] after receipt by either Party of a Notice of Termination or expiration of this Agreement.

Enforcement of the Licensor’s Intellectual Property

10.1	Third Party Infringement. Each Party shall inform the other Party promptly in writing of any alleged infringement of the Licensed Patents by a Third Party and of any available evidence thereof.

10.2

During the term of this Agreement, LICENSEE shall have the initial right, but not the obligation, to prosecute at its own expense any infringement of the Licensed Patents. If LICENSEE prosecutes any infringement, LICENSOR agrees that LICENSEE may include LICENSOR as a co-plaintiff in any such suit, and LICENSOR agrees to join in any such suit, without any expense to LICENSOR. The total cost of any infringement action commenced or defended by LICENSEE shall be borne by LICENSEE and LICENSEE shall keep all recovery or damages derived therefrom.

10.3	If after [***] of having been notified of any alleged infringement of the Licensed Patents or such shorter time proscribed by law, LICENSEE:

(a)

has been unsuccessful in persuading the alleged infringer to desist, or

(b)

has not brought and has not been diligently prosecuting an infringement action, or

(c)

if LICENSEE notifies LICENSOR at any time prior thereto of its intention not to bring suit against any alleged infringer, then, and in those events only, and subject to the rights of other co-owners of the Licensed Patents, LICENSOR shall have the right, but not the obligation, to prosecute at its own expense any infringement of the Licensed Patents, and LICENSOR may, for such purposes, require joinder of LICENSEE as involuntary parties to the litigation, provided, however, that such right to bring an infringement action remains in effect only for so long as the license granted herein remains exclusive. No settlement, consent judgment or other voluntary final disposition of the suit may be entered into without the consent of LICENSEE which consent shall not unreasonably be withheld, conditioned or delayed. LICENSOR shall indemnify LICENSEE against any order for costs that may be made against LICENSEE in such proceedings or any action arising there from, including without limitation, abuse of process and malicious prosecution. The total cost of any infringement action commenced or defended by LICENSOR shall be borne by LICENSOR and, subject to the rights of other co-owners of the Licensed Patents, LICENSOR shall keep all recovery or damages for past infringement derived therefrom.

10.4

In any infringement suit as either Party may institute to enforce the Licensed Patents pursuant to this Agreement, the other Party hereto shall, at the request and expense of the Party initiating such suit, cooperate in all respects and, to the extent possible, have its employees testify when requested and make available relevant records, papers, information, samples, specimens, and the like.

LICENSEE shall indemnify, defend and hold harmless LICENSOR, its directors, trustees, officers, faculty, employees, students, and agents and their respective successors, heirs and assignees (the “Indemnitees”), against any and all claims, suits, losses, liabilities, damages, costs, fees and expenses, including reasonable attorneys’ fees and expenses, incurred by or imposed upon any of the Indemnitees in connection with any claims, suits, actions or demands of Third Parties (“Claims”) asserted against them to the extent arising out of any theory of liability (including without limitation actions in the form of tort, product liability, negligence, warranty, strict liability, violation of government regulation, infringement of patent or other proprietary rights, breach of any representations or warranties by LICENSEE, failure by LICENSEE to perform any of its obligations under this Agreement, trademark or trade dress infringement arising out of the use of any trademark or trade dress by LICENSEE in connection with the Sale of Licensed Product, copyright infringement arising out of any material published by LICENSEE, and regardless of whether such action has any factual basis) concerning any Licensed Product that is made, used, Sold, distributed, supplied or provided, or any Licensed Method performed, pursuant to any right or license granted under this Agreement or any Sublicense, except to the extent that any Claims shall have arisen from the gross negligence or willful misconduct of any LICENSOR Indemnitee or the breach of this Agreement by any LICENSOR Indemnitee.

LICENSOR Indemnitee shall promptly notify LICENSEE of any Claim with respect to which such LICENSOR Indemnitee is seeking indemnification hereunder, upon becoming aware thereof, and permit LICENSEE at LICENSEE’s cost to defend against such Claim and shall cooperate in the defense thereof. Neither such LICENSOR Indemnitee nor LICENSEE shall enter into, or permit, any settlement of any such Claim without the express written consent of the other Party, which shall not unreasonably be withheld, conditioned or delayed. Such LICENSOR Indemnitee may, at its option and expense, have its own counsel participate in any proceeding which is under direction of LICENSEE and will cooperate with LICENSEE and its insurer in the disposition of any such matter; provided, however, that if LICENSEE shall not defend such Claim, such LICENSOR Indemnitee shall have the right to defend such Claim itself and recover from LICENSEE all reasonable attorneys’ fees and expenses incurred by it during the course of such defense.

11.2

Failure to Defend. With respect to any Claim which pursuant to Section 11.1, LICENSEE shall fail to defend, LICENSEE shall not thereafter question the liability of LICENSEE hereunder to the Indemnitee for any loss (including reasonable counsel fees and other reasonable expenses of defense) arising from such Claim.

GU Reference: 2016-058

11.3	Claims Period. Notwithstanding the foregoing, the indemnification provisions of Section 11.1 hereof shall survive termination or expiration of this Agreement, but only with respect to claims which arose from acts or circumstances which occurred prior to termination.

11.4

Insurance. LICENSEE shall obtain and carry in full force and effect, or shall provide through self-insurance, commercial general liability insurance, including product liability and errors and omissions insurance, which shall protect LICENSEE and Indemnitees with respect to events covered by Section 11.1 above. Such insurance (i) shall list LICENSOR as an additional insured thereunder, (ii) shall be endorsed to include product liability coverage, and (iii) shall require [***] written notice to be given to LICENSOR prior to any cancellation or material change thereof. The limits of such insurance shall be consistent with limits as are customary in the U.S. pharmaceutical industry for the activities to be conducted by LICENSEE under this Agreement. LICENSEE shall provide LICENSOR with Certificates of Insurance evidencing compliance with this Section. LICENSEE shall continue to maintain such insurance or self-insurance after the expiration or termination of this Agreement during any period in which LICENSEE or any SUBLICENSEE continues to make, use, or Sell a product that was a Licensed Product under this Agreement, and thereafter for a period of [***].

Confidential Information pertaining to the Licensed Patents shall be deemed Confidential Information of both Parties.

12.2

Each Party shall keep in confidence and shall each use its Commercially Reasonable Efforts to cause its respective officers, directors, employees, professors, researchers, students, trustees, regents, agents, consultants, clinical research associates and clinical investigators to whom it is permitted to disclose information pursuant to the terms of this Agreement to retain in confidence all Confidential Information of the disclosing Party and not use such Confidential Information for any purpose other than the Permitted Purpose.

2. LICENSE

2.1 Grant of License.

(a) Subject to the terms of this Agreement and BIDMC’s rights in the Patent Rights, BIDMC hereby grants to Licensee and its Affiliates in the Field in the Territory for the Term, an exclusive, royalty-free, fully paid-up (upon payment of the License Issue Fee pursuant to Section 3.1) license under BIDMC’s rights in the Patent Rights to make, have made, use, have used, Sell and have Sold Products and Processes.

(b) Subject to the terms of this Agreement and specifically Section 2.2, BIDMC grants Licensee the right to grant sublicenses under the rights granted in Section 2.1(a) and Section 2.1(c), provided that in each case Licensee shall be responsible for the performance of any obligations of Sublicensees relevant to this Agreement as if such performance were carried out by Licensee itself, which right to grant sublicenses will be exclusive with respect to the rights granted in Section 2.1(a) and will be non-exclusive with respect to the rights granted in Section 2.1(c).

(c) Subject to the terms of this Agreement, BIDMC hereby grants to Licensee and its Affiliates (subject to Section 2.1(e)) in the Field in the Territory for the

Term, a nonexclusive royalty-free, fully paid-up (upon payment of the License Issue Fee pursuant to Section 3.1) right to use Related Information disclosed by BIDMC to Licensee to develop, make, have made, use, have used, Sell and have Sold and otherwise commercialize the Products and Processes.

(d) The licenses granted in Sections 2.1(a) and 2.1(c) above include:

(i)

the right to grant to the purchaser, user or consumer of Products the right to use such purchased Products in a method coming within the scope of Patent Rights, and such purchasers, users and consumers will not be considered Sublicensees hereunder; and

(ii)

the right to grant a Distributor the right to Sell (but not to make, have made, use or have used) such Products and/or Processes for or on behalf of Licensee, Licensee Affiliates and Sublicensees in a manner consistent with this Agreement.

(e) The foregoing license grants to Licensee Affiliates are subject to each such

Affiliate assuming the same obligations as those of Licensee and becoming subject to the same terms and conditions under this Agreement; and further provided that Licensee shall be responsible for the performance of all of such obligations and for compliance with all of such terms and conditions by Affiliate.

2.2 Sublicenses. Each sublicense granted hereunder shall be consistent with and comply with all terms of this Agreement, and shall incorporate terms and conditions sufficient to enable Licensee to comply with this Agreement. Licensee shall provide to BIDMC a fully signed copy of all sublicense agreements and amendments thereto, including all exhibits, attachments and related documents, within [***] of executing the same, excluding sublicenses granted to third parties that are clinical research organizations, contract manufacturers, contract laboratory organizations, and other similar third parties that support the development and commercialization of Products and/or Processes on a fee-for-service basis as Sublicensees hereunder (“Third Party Contractors”). Licensee will be permitted to redact from such fully signed copies proprietary and other sensitive information to the extent that such redaction does not impact BIDMC’s ability to confirm Licensee’s compliance with this Agreement. Notwithstanding the foregoing, Licensee will disclose to BIDMC the identity of the Sublicensee (excluding, for avoidance of doubt, Third Party Contractors). Any sublicense which is not in accordance with the forgoing provisions shall be null and void. Any Sublicensee and Distributor agreement under this Agreement shall provide for termination of any sublicense granted hereunder upon termination of this Agreement for any reason. Upon termination of this Agreement for any reason, any Sublicensee and Distributor not then in default under its agreement shall have the right to seek a license from BIDMC. BIDMC agrees to negotiate such licenses in good faith under reasonable terms and conditions consistent with this Agreement.

Upon Licensee’s request during the term of this Agreement, BIDMC agrees to provide, on a timely basis, a letter to an existing or potential Sublicensee specifically named by Licensee stating that, in the event of termination of this Agreement, BIDMC will grant a license to Sublicensee under terms and conditions to be no less favorable as a whole than those granted to Sublicensee by Licensee, provided that Sublicensee is not in default of its sublicense agreement with Licensee at the time such license is to be granted by BIDMC and provided that BIDMC shall not assume any obligation of Licensee to Sublicensee under such agreement, except for the license granted. Licensee’s right to request and Sublicensee’s right to acquire such letter are specifically conditioned on BIDMC’s review of the final, executed sublicense agreement between Sublicensee and Licensee and on BIDMC’s conclusion, at its reasonable discretion, that such sublicense agreement is reasonable and in the best interests of the commercialization of the Patent Rights.

2.3 Retained Rights; Requirements. Any and all licenses granted hereunder are subject to:

(a) the royalty-free right of BIDMC and BIDMC’s Affiliates and of academic, government and not-for-profit institutions to make, use and/or practice the technology or method described and/or claimed in the Patent Rights solely for non-commercial research purposes; and

(b) for Patent Rights supported by federal funding, the rights, conditions and limitations imposed by U.S. law (see 35 U.S.C. § 202 et seq. and regulations pertaining thereto), including without limitation:

(i)

the royalty-free non-exclusive license granted to the U.S. government; and

(ii)

to the extent required by the National Institutes of Health (as the federal funding agency), the requirement that any Products (if they qualify as “subject inventions” under 35 U.S.C. § 204) used or sold in the United States shall be manufactured substantially in the United States.

If Licensee or any of its Affiliates or Sublicensees wishes to obtain a waiver of the requirement under Section 2.3(b)(ii), BIDMC agrees to reasonably cooperate with Licensee or such Affiliates or Sublicensees in obtaining such waiver, including by directly filing for such waiver if required by applicable law and regulations.

2.4 No Additional Rights. Nothing in this Agreement shall be construed to grant Licensee an express or implied license under any patent, technology or intellectual property right owned solely or jointly by BIDMC, other than the Patent Rights and Related Information expressly licensed hereunder.

3. PAYMENTS

3.1 License Issue Fee. Licensee shall pay BIDMC a non-refundable, non-creditable license issue fee in the sum of twenty thousand dollars ($20,000) (“License Issue Fee”) within twenty (20) business days of the Effective Date of this Agreement. For avoidance of doubt, upon payment of the License Issue Fee, the licenses and rights granted to Licensee under Section 2.1 shall be fully paid-up and royalty-free.

3.2 Form of Payment. All payments due under this Agreement shall be drawn on a United States bank and shall be payable in United States dollars. Each payment shall reference this Agreement and identify the obligation under this Agreement that the payment satisfies. Conversion of foreign currency to U.S. dollars shall be made at the conversion rate existing in the United States, as reported in The Wall Street Journal, on the last working day of the applicable Reporting Period. Such payments shall be without deduction of exchange, collection or other charges, and, specifically, without deduction of withholding or similar taxes or other government imposed fees or taxes. Checks for all payments due to BIDMC under this Agreement shall be made payable to BIDMC and addressed as set forth in Section 12.2. Payments via wire transfer should be made as follows:

[***]

3.3 Overdue Payments. The payments due under this Agreement shall, if overdue, bear interest at two percentage Points above the Prime Rate of interest as reported in the Wall Street Journal on the date payment is due until payment thereof, not to exceed the maximum permitted by law. Any such overdue payments when made shall be accompanied by all interest so accrued. Payment and acceptance, in whole or in part, of interest and the overdue payment shall not preclude BIDMC from exercising any other rights it may have as a consequence of the lateness of any payment.

3.4 Consequences of a Patent Challenge. In the event that (i) Licensee, any of its Affiliates, or any Sublicensee brings a Patent Challenge against BIDMC, or (ii) Licensee, any of its Affiliates, or any Sublicensee assists another party in bringing a Patent Challenge against BIDMC (except as required under a court order or subpoena), and (iii) BIDMC does not choose to exercise its rights to terminate this Agreement pursuant to Section 9.4, then if such a Patent Challenge is successful, Licensee will have no right to recoup any monies paid during the period of challenge.

4. PATENT PROSECUTION AND MAINTENANCE

4.1 Prosecution. Provided that Licensee seeks and maintains the strongest and broadest patent claims reasonably practicable and uses patent attorneys acceptable to BIDMC, such acceptance not to be unreasonably withheld, BIDMC appoints Licensee as its exclusive agent to prepare, file, prosecute (including to seek extensions of), maintain and defend (including inter partes and opposition proceedings) all of the Patent Rights

during the Term. Licensee shall copy BIDMC on all patent prosecution documents and give BIDMC reasonable opportunities to advise Licensee on such filing, prosecution, maintenance and defense. BIDMC shall reasonably cooperate with Licensee in the filing, prosecution, maintenance and defense of the Patent Rights. Such cooperation includes promptly executing all documents, or requiring inventors, subcontractors, employees and consultants and agents of BIDMC and its Affiliates to execute all documents, and joining as a party in any proceedings, as reasonable and appropriate so as to enable the filing, prosecution, maintenance and defense of any Patent Right in any country. In the event Licensee desires to abandon the prosecution, maintenance or defense of any patent, patent application, or any Claims within the Patent Rights where such Claims are not included in a continuation, divisional or other patent or patent application, Licensee shall provide BIDMC with [***] prior written notice of such intended abandonment or decline of responsibility and, as to Claims, shall reasonably consider BIDMC’s judgment in whether or not to abandon or not defend such Claim, and, as to such patent or patent application, such abandonment or election not to defend shall only be with prior notice to BIDMC on a patent by patent and country by country basis. If BIDMC desires to prosecute, maintain or defend any such Patent Rights proposed to be abandoned by Licensee under this Agreement, the right to prepare, file, prosecute, maintain and defend the relevant Patent Rights shall revert, as between Licensor and Licensee, to BIDMC, at BIDMC’s expense, subject to any third party rights. In such event, such BIDMC paid-for rights shall be removed from the definition of Patent Rights under this Agreement, the licenses granted to Licensee and its Affiliates as to such Patent Rights shall terminate, and BIDMC shall have the right to abandon or maintain and license such Patent Rights in its discretion.

4.2 Confidentiality of Prosecution and Maintenance Information. Each Party agrees to treat all information related to prosecution and maintenance of Patent Rights as Confidential Information in accordance with the provisions of Appendix B.

5. REPORTS

5.1 Progress Reports. Within [***] after the end of each calendar year, Licensee shall report in writing to BIDMC on progress during such preceding [***] period in developing and/or commercializing Products and/or Processes, including, without limitation, progress on research and development, status of applications for regulatory approvals, manufacturing, sales, sublicensing and the number of sublicenses (excluding Third Party Contractors) entered into and marketing.

6. THIRD PARTY INFRINGEMENT AND LEGAL ACTIONS

6.1 Licensee Right to Prosecute. Licensee shall have the first right, but not the obligation, to initiate legal proceedings to protect the Patent Rights from infringement, with respect to a Claim of a Patent Right in the Field in the Territory, and prosecute infringers at Licensee’s expense. Before commencing such action, Licensee and, as applicable, any Affiliate, shall consult with BIDMC, concerning the advisability of bringing suit, the selection of counsel and the jurisdiction for such action (provided

Licensee must have BIDMC’s prior written consent (not to be unreasonably withheld) with respect to selection of jurisdiction for any action in which BIDMC may be joined as a party-plaintiff) and shall use reasonable efforts to accommodate the views of BIDMC regarding the proposed action, especially but without limitation with respect to potential effects on the public interest. Licensee shall be responsible to BIDMC for all costs, expenses and liabilities arising out or and in connection with any such action and shall indemnify and hold BIDMC harmless therefrom, regardless of whether BIDMC is a party-plaintiff, except for the expense of any independent counsel retained by BIDMC in accordance with Section 6.2 below. Licensee shall keep BIDMC informed of the progress of such proceedings and shall make its counsel reasonably available to BIDMC for discussion of such proceedings. BIDMC shall also be entitled to independent counsel in such proceedings but at its own expense, said expense to be offset against any damages received by the Licensee bringing suit in accordance with Section 6.4

6.2 BIDMC Right to Prosecute and/or Join as a Party-Plaintiff.

(a) In the event that Licensee elects not to take action pursuant to this Section 6.1, Licensee shall so notify BIDMC promptly in writing of its intention in good time to enable BIDMC to meet any deadlines by which an action must be taken to establish or preserve any enforcement rights and BIDMC shall have the right to take steps to protect the Patent Rights from infringement, with respect to a Claim of a Patent Right in the Field in the Territory, and prosecute infringers at BIDMC’s expense and subject to any third party rights. If BIDMC notifies Licensee that it intends to so prosecute, subject to any third party rights, BIDMC shall use reasonable efforts, within [***] of its notice to Licensee, to (i) cause such infringement to terminate; (ii) reach a settlement with infringers; or (iii) initiate legal proceedings against the infringer. Nothing in this Section 6.2 shall be construed to prevent Licensee from initiating legal proceedings, in accordance with its independent judgement of the merits of an infringement action, as provided in Section 6.1.

(b) If Licensee elects to commence an action as described in Section 6.1 above, BIDMC shall have, in its sole discretion and at its own expense, the option to voluntarily join such action as a party-plaintiff. If required by law for the purposes of Licensee bringing an action against an alleged infringer, BIDMC agrees that it shall allow Licensee to join BIDMC in such action as a party-plaintiff

6.3 Notice of Actions; Settlement. Licensee shall promptly inform BIDMC of any action or suit relating to Patent Rights and shall not enter into any settlement, consent judgment or other voluntary final disposition of any action relating to Patent Rights, including but not limited to appeals, that would adversely affect the validity, patentability or enforceability of the Patent Rights without the prior written consent of BIDMC, which shall not be unreasonably withheld or delayed.

6.4 Recovery. Subject to any third party rights, any award paid by third parties as the result of such proceedings (whether by way of settlement or otherwise) shall first be applied to reimbursement of any legal fees and expenses incurred by both Parties, in proportion to their expenditures, and then the remainder, if any, shall be distributed between the Parties as follows:

(a) Licensee shall receive an amount equal to its lost profits or a reasonable royalty on the infringing sales, or whichever measure of damages the court shall have applied; and

(b) the balance, if any, remaining after Licensee and BIDMC have been compensated under Section 6.4(a) shall be shared equally by the Parties.

7. INDEMNIFICATION AND INSURANCE

7.1 Indemnification.

(a) Licensee shall indemnify, defend and hold harmless BIDMC and its Affiliates and their respective trustees, directors, officers, medical and professional staff, employees, and agents and their respective successors, heirs and assigns (the “Indemnitees”), against any liability, damage, loss or expense (including reasonable attorney’s fees and expenses of litigation) incurred by or imposed upon the Indemnitees or any one of them in connection with any claims, suits, actions, demands or judgments commenced or obtained by a third party arising out of any theory of liability, including without limitation, any theory of product liability (including, but not limited to, actions in the form of contract, tort, warranty, or strict liability) concerning any Product or Process made, used or sold pursuant to any right or license granted under this Agreement. BIDMC shall promptly provide written notice to Licensee of any claim to which indemnification applies under this Section 7.1(a).

(b) Licensee agrees, at its own expense, to, defend against and resolve, and will have the right to assume and control the defense and resolution of, any actions or claims brought or filed against any party indemnified hereunder with respect to the subject of indemnity contained herein, whether or not such actions are rightfully brought; provided, however, that any Indemnitee shall have the right to retain its own counsel, at the expense of Licensee, if representation of such Indemnitee by counsel retained by Licensee would be inappropriate because of actual or potential conflicts of interests of such Indemnitee and any other party represented by such counsel. Licensee agrees to keep BIDMC informed of the progress in the defense and disposition of such claim and to consult with BIDMC prior to any proposed settlement. The party indemnified hereunder will reasonably cooperate with Licensee at Licensee’s expense and will make available to Licensee relevant information under the control of such indemnified party.

(b) This Section 7.1 shall survive expiration or termination of this Agreement.

7.2 Insurance.

(a) Beginning at such time as any Product or Process licensed under this Agreement is being commercially distributed, sold, leased or otherwise transferred, or performed or used (other than for the purpose of obtaining regulatory approvals), by Licensee, Licensee shall, at its sole cost and expense, procure and maintain commercial general liability insurance in amounts not less than $[***] per incident and $[***] annual aggregate and naming the Indemnitees as additional insureds. Such commercial general liability insurance shall provide (i) product liability coverage and (ii) broad form contractual liability coverage for the indemnification obligations under Section 7.1 of this Agreement. If Licensee or its Affiliates or Sublicensees elects to self-insure all or part of the limits described above (including deductibles or retentions which are in excess of $[***] annual aggregate), such self-insurance program must be reasonably acceptable to the Licensor, provided that if a Sublicensee elects to self-insure and such Sublicensee has a market capitalization of at least [***] dollars ($[***]), then such Sublicensee’s self-insurance program shall automatically be deemed reasonably acceptable to Licensor and not subject to Licensor’s review. The minimum amounts of insurance coverage required under this Section 7.2 shall not be construed to create a limit of liability with respect to the indemnification obligations under Section 7.1 of this Agreement.

(b) Licensee shall provide BIDMC with written evidence of such insurance upon request of BIDMC. Licensee shall provide BIDMC with written notice at least [***] prior to the cancellation, non-renewal or material change in such insurance; if Licensee does not obtain replacement insurance providing comparable coverage prior to the expiration of such [***] period, BIDMC shall have the right to terminate this Agreement pursuant to Section 9.3 (and subject to the cure right therein).

(c) Licensee shall maintain such commercial general liability insurance beyond the expiration or termination of this Agreement during (i) the period that any such Product or Process, is being commercially distributed, sold, leased or otherwise transferred, or performed or used (other than for the purpose of obtaining regulatory approvals), by Licensee or by a licensee, affiliate or agent of Licensee and (ii) a reasonable period after the period referred to in (c) (i) above which in no event shall be less than [***].

(d) This Section 7.2 shall survive expiration of termination of this Agreement.

7.3 Affiliates and Sublicensees. Licensee shall require all its Affiliates and Sublicensees (other than Third Party Contractors) to comply with the provisions and obligations under this Section 7 as if such entity were the Licensee.

8. REPRESENTATION; DISCLAIMER OF WARRANTIES; LIMITATION OF LIABILITY

8.1 Representation. To the best knowledge of BIDMC’s Technology Ventures Office, BIDMC represents that:

(a) No approval, authorization, consent or other order or action of or filing with any court, administrative agency or other governmental authority is required for the execution and delivery by it of this Agreement or the consummation by it of the transactions contemplated hereby;

(b) it has full right and authority to enter into this Agreement and to grant the licenses and other rights to Licensee as herein described;

(c) the execution, delivery and performance of this Agreement does not conflict with any other agreement, contract, instrument or understanding, oral or written, to which BIDMC is a party, or by which it is bound; and

(d) none of BIDMC nor any of its Affiliates has entered into any agreement or otherwise licensed, granted, assigned, transferred, conveyed or otherwise encumbered or disposed of any right, title or interest in or to any of the Patent Rights that would conflict with or impair the scope of any rights or licenses granted hereunder.

8.2 No Warranties. BIDMC HEREBY DISCLAIMS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, CONCERNING THE PATENT RIGHTS AND ANY OF THE RIGHTS GRANTED HEREUNDER, INCLUDING, WITHOUT LIMITATION, WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, VALIDITY OF PATENT RIGHTS CLAIMS, WHETHER ISSUED OR PENDING, AND THE ABSENCE OF LATENT OR OTHER DEFECTS, WHETHER OR NOT DISCOVERABLE.

The failure of either Party at any time or rimes to require performance of any provision hereof shall in no manner affect its rights at a later time to enforce the same.
