 Each milestone payment in this Section 6.6 is due only once and shall be payable only upon the first
achievement of such milestone event, with respect to Program 1 or Program 2, regardless of whether there has been a Replacement Target for any original [***], neither of which has been the subject of any other milestone payment under this
Section 6.6 and no amounts shall be due under this Section 6.6 for subsequent or repeated achievements of any such milestone event regardless of whether milestone event 1 or 2 is achieved with respect to any Replacement Target [***] with
respect to which milestone payment 1 or 2 has previously been paid. For clarity, the maximum aggregate amount of milestone payments payable by Takeda pursuant to this Section 6.6 is [***]. 

Section 6.7 Sales Milestone Payments. Subject to the terms and conditions of this Agreement, Takeda
shall pay to MTEM the following sales milestone payments [***] after the end of the first Calendar Year in which the aggregate annual Net Sales of all Licensed Products Directed to each Licensed Target in such Calendar Year reach the following
thresholds for the first time:

 Each sales milestone payment is separate and may only be earned once for the aggregate of all Licensed
Products for each Licensed Target, however, if more than one Net Sales threshold is reached in the same Calendar Year, [***] payments shall be payable during such Calendar Year. For example, if annual Net Sales of all Licensed Products for a
Licensed Target first reach [***] in Calendar Year 1, [***] shall be payable to MTEM for such Calendar Year 1, however, if annual Net Sales of all Licensed Products for a Licensed Target first reach [***] (without first reaching [***] in Calendar
Year 1), then [***] would be payable to MTEM for Calendar Year 2 and [***] would be payable to MTEM [***]. For clarity, the maximum aggregate amount of milestone payments payable by Takeda pursuant to this Section 6.7 is [***]. 

Section 6.8 Royalties Payable by Takeda. 

6.8.1 In consideration for the Exclusive Licenses granted to Takeda herein, and subject to the terms and conditions of this Agreement,
during the applicable Royalty Term for a Licensed Product, on a Licensed Target-by-Licensed Target basis, Takeda shall pay to MTEM royalties on the annual aggregate Net
Sales of all Licensed Products Directed to such Licensed Target in the Territory during the applicable Royalty Term for such Licensed Product (but excluding any Net Sales in any country for which the Royalty Term for such Licensed Product in such
country is not in effect), which royalties shall be paid at the following rates as set forth below: 
  

			
	 Annual Net Sales for all Licensed Products Directed to a Licensed
Target
	  	Royalty Rate
	 For the portion of aggregate Net Sales of all Licensed Products for such Licensed Target in any
given Calendar Year of less than [***]
	  	[***]
	 For the portion of aggregate Net Sales of all Licensed Products for such Licensed Target in any
given Calendar Year equal to or greater than [***] and less than [***]
	  	[***]
	 For the portion of aggregate Net Sales of all Licensed Products for such Licensed Target in any
given Calendar Year equal to or greater than [***] and less than [***]
	  	[***]
	 For the portion of aggregate Net Sales of all Licensed Products for such Licensed Target in any
given Calendar Year equal to or greater than [***] and less than [***]
	  	[***]
	 For the portion of aggregate Net Sales of all Licensed Products for such Licensed Target in any
given Calendar Year equal to or greater than [***]
	  	[***]

  

  
 Portions of this Exhibit,

Exchange Act of 1934, as amended. 
 Page 38 








 For avoidance of doubt, the incremental royalty rates set forth above shall only apply to that
portion of the Net Sales of royalty-bearing Licensed Products for the Licensed Target that falls within the indicated range of sales. By way of example, and not in limitation of the foregoing, if, during a Calendar Year, Net Sales of the Licensed
Products, in the aggregate, for a Licensed Target were equal to [***], the royalty payable by Takeda would be calculated by adding (i) the royalty due on Net Sales with respect to the first [***] at the first level percentage of [***], and
(ii) the royalty due on Net Sales for the Licensed Target with respect to the next [***] at the second level percentage of [***]. The obligation to pay royalties shall be imposed only once with respect to the same unit of Licensed Product sold
by Takeda, its Affiliate or Sublicensee. Takeda shall have no obligation to pay any royalty with respect to Net Sales of any Licensed Product in any country after the Royalty Term for such Licensed Product in such country is not in effect. 

6.8.2 Royalty Reductions. 

(a) If and for so long as there is a Biosimilar Product or Generic Product being sold by a Third Party in a Calendar Quarter in a
country in the Territory, then the royalties otherwise payable by Takeda to MTEM in such country pursuant to Section 6.8 above shall be reduced by the percent set forth below of the amounts otherwise owed: 

 

			
	 Biosimilar Products or Generic Products unit

volume sales for each Licensed Product in such
 country,
as a percentage of total sales of Licensed
 Products, on the one hand, and Biosimilar

Products and Generic Products, on the other

hand, in such country
	  	 Reduction rate

	 [***]
	  	[***]
	 Greater than [***] up to [***]
	  	[***]
	 Greater than [***] up to [***]
	  	[***]
	 Greater than [***] up to [***]
	  	[***]
	 Greater than [***]
	  	[***]

 The Parties will select a mutually agreeable independent Third Party to identify and calculate the Biosimilar Products or
Generic Products unit volume sales for each Licensed Product in a Calendar Quarter in a country in the Territory and such unit volume sales amounts shall be included in each royalty report provided for under Section 6.144. In the event that
such independent Third Party is not available or 

  
 Portions of this Exhibit,
indicated by the mark “[***],” were omitted and have been filed separately with the Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 24b-2 of the Securities
Exchange Act of 1934, as amended. 
 Page 39 








 
otherwise able to accurately determine or calculate the Biosimilar Product or Generic Product unit volume sales, Takeda shall calculate the Biosimilar Product or Generic Product unit volume sales
based on available data in good faith. In the event MTEM disputes Takeda’s calculation of any Biosimilar Product or Generic Product unit volume sales for a Licensed Product in a country in the Territory, MTEM may by written notice to
Takeda require, at MTEM’s cost, that such dispute be resolved in accordance with Section 12.3 by and submitted to a panel of experts; provided, that Takeda shall have the right to take royalty reductions pursuant to this Section 6.8.2
pending resolution of any such dispute, calculated using its good faith calculation of the Biosimilar Product or Generic Product unit volume sales pursuant to the preceding sentence. 

(b) Subject to the last sentence of Section 6.8.1, from and after the date on which a Licensed Product is Exploited in a country
that is not covered by a Valid Claim(s) of the MTEM Background Patent Rights, the SLT-A Program Patent Rights or the Target Program Patent Rights (other than Targeting Moiety IP) in such country, the
royalty rates set forth in Section 6.8 with respect to such country shall each be [***], provided that the royalty rates shall be adjusted from [***] during the Royalty Term should a Valid Claim be granted in such country; 

(c) [***] in accordance with Section 8.7.2. 

(d) If and for so long as Takeda makes payments to any Third Party in consideration for a license from a Third Party pursuant to
Section 8.9, Takeda may reduce the royalty payments, otherwise due as set forth in Section 6.8 [***] of the amount paid to the Third Party; provided, however, that such reductions, in the aggregate, may not reduce the average effective
royalty by more than [***] points of such rate. Takeda may carry forward, and deduct from future royalty payments due hereunder, any amounts which cannot be deducted under this clause (d) due to the proviso in the immediately prior sentence.

 (e) Any reductions set forth in Section 6.8.2 shall be (i) applied to the royalty rate payable to MTEM under
Section 6.8.1 first as set forth in Section 6.8.2(a), then Section 6.8.2(b), then Section 6.8.2(c) and then Section 6.8.2(d), and (ii) with respect to Net Sales in a country in which any such reduction is triggered,
allocated across the applicable rates set forth in Section 6.8.1 on a pro rata basis in proportion to the Net Sales in such country compared to Net Sales throughout the Territory, excluding in each case, any Net Sales in a country for which the
Royalty Term for such Licensed Product in such country has expired, from and after the date of such expiration. 
 (f) MTEM
acknowledges and agrees that the sales levels set forth in this Section 6.8 and Section 6.7 shall not be construed as representing an estimate or projection of anticipated sales of the Licensed Products or implying any level of diligence
or Commercially Reasonable Efforts in the Territory and that the sales levels set forth in Section 6.7 and Section 6.8 are merely intended to define Takeda’s royalty and other payment obligations, as applicable, in the event such
sales levels are achieved and that the sales levels set forth in Section 6.7 and Section 6.8 are merely intended illustrative purposes only. 

Section 6.9 Payment Terms. Royalties shown to have accrued by each Royalty Report provided for under
this Article VI shall be due on the date such Royalty Report is due pursuant to Section 6.14.2. 

Section 6.10 Payment Method. All payments by Takeda to MTEM under this Agreement shall be paid in U.S.
Dollars, and all such payments shall be made by bank wire transfer in immediately available funds to the bank account designated by MTEM in writing; provided, that such account information is provided to Takeda at [***] to any such payment becoming
due hereunder.

indicated by the mark “[***],” were omitted and have been filed separately with the Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 24b-2 of the Securities
Exchange Act of 1934, as amended.

 Section 6.11 Late Payments. If a Party does not receive
payment of any sum due to it on or before the due date therefor, simple interest shall thereafter accrue on the sum due to such Party from the due date until the date of payment at a per-annum rate of [***]
over the then-current Prime Rate reported in The Wall Street Journal or the maximum rate allowable by Applicable Law, whichever is lower. 

Section 6.12 Exchange Control. If at any time legal restrictions prevent the prompt remittance of part
or all royalties with respect to any country in the Territory where any Licensed Product is sold, payment shall be made through such lawful means or method as the Parties reasonably shall determine. 

Section 6.13 Taxes; Withholding Taxes. Except as otherwise provided below, all amounts due from Takeda
to MTEM under this Agreement are gross amounts. Takeda shall be entitled to deduct the amount of any withholding taxes payable or required by Applicable Law to be withheld by Takeda, its Affiliates or Sublicensees, to the extent Takeda, its
Affiliates or Sublicensees pay such withheld amounts to the appropriate Governmental Authority on behalf of MTEM. Takeda promptly shall deliver to MTEM proof of payment of any withholding taxes, together with copies of all communications from or
with such Governmental Authority with respect thereto, and other supporting documentation as may be required by the Governmental Authority, and shall provide reasonable cooperation with MTEM in seeking any related tax exemption or credits that may
be available to MTEM with respect thereto. MTEM shall cooperate with Takeda in seeking any tax exemption or credits that may be available to Takeda with respect to the SLT-A Fusion Proteins, Licensed Products
or Targets, including the tax credit available under section 45C of the Internal Revenue Code by reason of Takeda’s research and development expenditures contributing to any Licensed Product being granted orphan drug status by the FDA. 

Section 6.14 Reports; Exchange Rates. 

6.14.1 For so long as any Royalty Term remains in effect, Takeda shall, with respect to each Calendar Quarter (or portion thereof),
provide a written report showing, on a consolidated aggregated basis in reasonable detail (a) the gross sales of Licensed Products sold by Takeda, its Affiliates and its Sublicensees in the Territory during the corresponding Calendar Quarter on
which royalties are due hereunder and the Net Sales from such gross sales, (b) the royalties payable in U.S. Dollars, if any, which shall have accrued hereunder based upon such Net Sales of Licensed Products, (c) the withholding taxes, if
any, required by law to be deducted in respect of such royalties, (d) the dates of the First Commercial Sale of each Licensed Product in each country in the Territory for which royalties are due hereunder, if it has occurred during the
corresponding Calendar Quarter, and (e) the exchange rates (as determined pursuant to Section 6.14.3 herein) used in determining the royalty amount expressed in U.S. Dollars (each, a “Royalty Report”). 

6.14.2 Royalty Reports shall be due within [***] following the end of the Calendar Quarter to which such Royalty Report relates. Takeda
shall keep complete and accurate records in sufficient detail to properly reflect all gross sales and Net Sales and to enable the royalties payable hereunder to be determined. 

6.14.3 With respect to sales of Licensed Products invoiced in U.S. Dollars, the gross sales, Net Sales, and royalties payable shall be
expressed in U.S. Dollars. With respect to sales of Licensed Products invoiced in a currency other than U.S. Dollars, the gross sales, Net Sales and royalties payable shall be expressed in the currency of the invoice issued by the Party making the
sale together with the U.S. Dollars equivalent of the royalty due, calculated using the average quarter-end rate of exchange for a given Calendar Quarter published in the East Coast Edition of the Wall Street
Journal during the applicable Calendar Quarter.

 Section 6.15 Audits. 

6.15.1 Upon the written request of a Party and with at least [***] prior written notice, but not [***], the other Party shall permit an
independent certified public accounting firm of internationally recognized standing, selected by such first Party and reasonably acceptable to such other Party, at such first Party’s sole cost and expense (except as set forth in this
Section 6.155), to have access during normal business hours to such of the records of such other Party as required to be maintained under this Agreement to verify the accuracy of the Royalty Reports due hereunder, in the case of MTEM, or to
verify the accuracy of the Supply Price, in the case of Takeda. Such accountants may audit records relating to Royalty Reports or the Supply Price, as applicable, made for any year ending not more than [***] prior to the date of such request. The
accounting firm shall disclose to the Party requesting such audit only whether the Royalty Reports or the Supply Price, as applicable, were correct or not, and the specific details concerning any discrepancies and such information shall be shared at
the same time with the other Party. No other information obtained by such accountants shall be shared with the Party requesting such audit. 

6.15.2 If such accounting firm concludes that any royalties were owed but not paid to MTEM, Takeda shall pay the additional royalties
within [***] following the date MTEM delivers to Takeda such accounting firm’s written report so concluding, together with the interest payment required by Section 6.11. If such accounting firm concludes that the Supply Price charged by
MTEM was inconsistent with the definition therefor and such inconsistency resulted in an overpayment by Takeda hereunder, MTEM shall reimburse Takeda such overpayment within [***] following the date Takeda delivers to MTEM such accounting
firm’s written report so concluding, together with the interest payment required by Section 6.111. The fees charged by such accounting firm shall be paid by the Party requesting such audit; provided, that if the audit discloses that
(a) the royalties payable by Takeda for the audited period are more than [***] of the royalties actually paid for such period, then Takeda shall pay the reasonable fees and expenses charged by such accounting firm or (b) the Supply Price
payable by Takeda for the audited period is less than [***] of the Supply Price actually paid for such period, then MTEM shall pay the reasonable fees and expenses charged by such accounting firm. If such accounting firm concludes that the royalties
paid were more than what was owed during such period, MTEM shall refund the overpayments within thirty (30) days following the date MTEM receives such accounting firm’s written report so concluding. 

Section 6.16 Confidential Financial Information. The Parties shall treat all financial information
subject to review under this Article VI or under any sublicense agreement as Confidential Information of such Party as set forth in Article VII, and shall cause its accounting firm to retain all such financial information in confidence under terms
substantially similar to those set forth in Article VII and with respect to each inspection, the independent accounting firm shall be obliged to execute for each Party’s benefit a reasonable confidentiality agreement prior to commencing any
such inspection. 
 Section 6.17 University IP. All Know-How and
inventions (and all Patent Rights and intellectual property or other proprietary rights) generated by [***] or individuals working on his behalf reasonably related to the use or development of methods of making or screening, libraries of, or
compositions of cytotoxic proteins identified therefrom, specific Targeting Moieties and any Improvements to any of the foregoing whether at, or on behalf of, University Health Network, Ontario Cancer Institute, or otherwise, have been assigned to
MTEM or one of its Affiliates and any milestones or royalties that may be due thereunder will be paid solely by MTEM. For clarity, none of the aforementioned IP falls within the scope of MTEM Background
Know-How.

 ARTICLE VII 

CONFIDENTIALITY 

Section 7.1 Non-Disclosure Obligations. Except as otherwise
provided in this Article VII during the Term and for a period of [***] thereafter, each Party and their respective Affiliates shall maintain in confidence, and use only for purposes as expressly authorized and contemplated by this Agreement, all
Confidential Information. “Confidential Information” means all confidential or proprietary information (including information relating to such Party’s research programs, development, marketing and other business practices and
finances), data, documents or other materials supplied by the other Party or their respective Affiliates under this Agreement, including such information that is marked or otherwise identified as “Confidential”; provided that,
notwithstanding anything to the contrary, Confidential Information constituting Program IP or relating exclusively to Designated Targets or Licensed Targets (“Product Information”) shall be considered the Confidential Information of
both MTEM and Takeda (except for any Target Program IP, which shall in all cases constitute the Confidential Information of Takeda only (and MTEM shall be considered the receiving Party with respect thereto regardless of which Party generated such
Target Program IP) and (c) the terms of this Agreement shall be Confidential Information of both Parties (and both Parties shall be deemed the receiving Party with respect thereto). Without limiting the foregoing, each Party shall use at least
the same standard of care as it uses to protect its own Confidential Information to ensure that its and its Affiliates’ employees, agents, consultants, clinical investigators and any sublicensees or subcontractors only make use of the other
Party’s Confidential Information for purposes as expressly authorized and contemplated by this Agreement and do not disclose or make any unauthorized use of such Confidential Information. 

Section 7.2 Permitted Disclosures.  

7.2.1 Notwithstanding the foregoing, but subject to the last sentence of this Section 7.2, the provisions of Section 7.1 shall
not apply to information, documents or materials that the receiving Party can conclusively establish: 
 (a) have become published or
otherwise entered the public domain or become generally available to the public other than by breach of this Agreement by the receiving Party or its Affiliates; 

(b) are permitted to be disclosed by prior consent of the other Party; 

(c) have become known to the receiving Party by a Third Party, provided such Confidential Information was not obtained by such Third
Party directly or indirectly from the disclosing Party on a confidential basis; 
 (d) prior to disclosure under this Agreement, was
already in the possession of the receiving Party, its Affiliates or Sublicensees; or 
 (e) have been independently developed by or
for the receiving Party without reference to the disclosing Party’s Confidential Information; 
 provided that the exceptions described in clauses
(d) and (e) shall not apply with respect to Confidential Information constituting (i) SLT-A Program Know-How that was conceived, discovered, developed or
otherwise made by Takeda, (ii) Target Program Know-How conceived, discovered, developed or otherwise made by MTEM or (iii) Product Information. 

  
 Portions of this Exhibit,

 7.2.2 Each Party may also disclose Confidential Information as set forth below in this
Section 7.2.2. Notwithstanding the disclosures permitted under Section 7.2.2, any Confidential Information so disclosed shall remain subject to the confidentiality obligations of Section 7.1, unless and until any exceptions described
in Section 7.2.1 shall apply. Either Party may disclose Confidential Information to the extent such disclosure is made: 
 (a)
in response to a valid order of a court of competent jurisdiction or other Governmental Authority or Regulatory Authority or, if in the reasonable opinion of the receiving Party’s legal counsel, such disclosure is otherwise required by
Applicable Law, including by reason of filing with securities regulators (including the rules and regulations of any stock exchange or trading market on which the disclosing Party’s (or its parent’s) securities are traded); provided, that
the receiving Party shall first have given notice to the disclosing Party and given the disclosing Party a reasonable opportunity to quash such order or to obtain a protective order or confidential treatment requiring that the Confidential
Information and documents that are the subject of such order or requirement be held in confidence by such court or agency or, if disclosed, be used only for the purposes for which the order was issued; provided, further, that the Confidential
Information disclosed in response to such court or governmental order or Applicable Law shall be limited to that information which is legally required to be disclosed in response to such court or governmental order or Applicable Law (including the
rules and regulations of any stock exchange or trading market on which the disclosing Party’s (or its parent’s) securities are traded); 

(b) in the case of the Party controlling prosecution of the applicable Program Patent Rights, solely to the extent reasonably necessary
to include in a patent application claiming Program Patent Rights; provided, that the Party filing the patent application shall provide at least [***] prior written notice of such disclosure to the other Party, reasonably consider the other
Party’s comments in good faith and take reasonable and lawful actions to avoid or minimize the degree of disclosure; 
 (c) by
Takeda, to a Regulatory Authority, as reasonably required or useful in connection with any filing, submission or communication with respect to any SLT-A Fusion Protein or Licensed Product; provided,
that reasonable measures shall be taken to assure confidential treatment of such information, to the extent such protection is available; 

(d) by MTEM, to a Regulatory Authority, as reasonably required or useful in connection with any filing, submission or communication
with respect to any SLT-A related product excluding any SLT-A Fusion Protein or Licensed Product; provided, that reasonable measures shall be taken to assure
confidential treatment of such information, to the extent such protection is available; 
 (e) to a Sublicensee or Distributor as
permitted hereunder; provided, that such Sublicensee or Distributor is then subject to obligations of confidentiality and limitations on use of such Confidential Information substantially similar to those contained herein and Takeda otherwise
complies with Section 3.5; 
 (f) by Takeda, its Affiliates or its or their Sublicensees to an actual or potential Third Party
Manufacturing, Development or Commercialization collaborator, Distributor, contractor or partner with respect to a Takeda Target, SLT-A Fusion Protein or Licensed Product or otherwise as may be necessary or
useful in connection with its exercise of rights or performance of obligations hereunder (including in connection with any litigation with respect thereto); provided, that such Third Party recipient is, if practicable, then subject to obligations of
confidentiality and limitations on use of such Confidential Information substantially similar to those contained herein;

 (g) by Takeda or to an actual or potential investor in or acquirer of the business to
which this Agreement relates; provided, that (i) such Third Party recipient is then subject to obligations of confidentiality and limitations on use of such Confidential Information substantially similar to those contained herein and
(ii) Takeda shall provide at least [***] prior notice of (including a copy of) any such proposed disclosure to MTEM and shall not make any such disclosure without first obtaining MTEM’s prior written consent (which consent shall not be
unreasonably withheld, conditioned or delayed) with respect thereto in each instance (it being understood that if consent with respect to a specific disclosure is given by MTEM with respect to a particular type of audience of Third Parties
(e.g., investors not affiliated with a pharmaceutical company), Takeda may subsequently make such specific disclosure to another member of such audience consistent with such consent without obtaining specific consent from MTEM in such
instance); and 
 (h) by MTEM to actual or potential strategic partners, investors or acquirers; provided, that such disclosures
shall be limited to the terms of this Agreement and pre-clinical data and pre-clinical results arising out of a Program and shall be limited disclosures that do
not divulge or otherwise make available (i) the identity of any Takeda Target, (ii) the identity of any SLT-A Fusion Protein or any Takeda Targeting Moiety used in the Program, or (iii) the
identity of Takeda or any of its Affiliates or Sublicensees; provided, further, that, in each case, (x) such Third Party recipient is then subject to obligations of confidentiality and limitations on use of such Confidential Information
substantially similar to those contained herein, and (y) MTEM shall provide at least [***] prior notice of (including a copy of) any such proposed disclosure to Takeda and shall not make any such disclosure without first obtaining Takeda’s
prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed) with respect thereto in each instance (it being understood that if consent with respect to a specific disclosure is given by Takeda with respect to a
particular type of audience of Third Parties (e.g., investors not affiliated with a pharmaceutical company), MTEM may subsequently make such specific disclosure to another member of such audience consistent with such consent without obtaining
specific consent from Takeda in such instance). 
 Section 7.3 Press Releases and Other Disclosures to Third
Parties. Neither MTEM nor Takeda will, without the prior consent of the other, issue any press release or make any other public announcement or furnish any statement to any Person (other than either Parties’ respective Affiliates)
concerning the existence of this Agreement, its terms and the transactions contemplated hereby, except for (a) the initial press release, which will be mutually agreed upon by the Parties as soon as practicable following the Effective Date,
(b) disclosures made in compliance with Section 7.1, Section 7.2 and Section 7.4, (c) disclosures made to attorneys, consultants, and accountants retained to represent the Parties in connection with the negotiation and
consummation of the transactions contemplated hereby, and (d) press releases by Takeda, in its sole discretion, regarding Takeda’s activities under this Agreement with respect to a Licensed Product following exercise of the Option with
respect to the applicable Designated Target. In addition, if so required, first approval by a Party of the contents of a press release or public disclosure shall constitute permission of a Party to use such same contents subsequently, without
submission of the press release or public disclosure to a Party for approval. 
 Section 7.4 Use of
Name. Except as expressly provided herein, neither Party shall mention or otherwise use the name, logo or trademark of the other Party or any of its Affiliates or any of its or their Sublicensees (or any abbreviation or adaptation thereof)
(including any Product Trademark) in any publication, press release, marketing and promotional material or other form of publicity without the prior written consent of such other Party. The restrictions imposed by this Section 7.4 shall not

any disclosure identifying the other Party that is required by Applicable Law or the rules of a stock exchange on which the securities of the disclosing Party are listed (or to which an application for listing has been submitted). 

Section 7.5 Publications Regarding Results of the Programs. Neither Party may publish, present or
announce results of the Programs hereunder either orally or in writing (a “Publication”) without complying with the provisions of this Section 7.5; provided that, without limiting what is below, from and after Takeda’s

Party on any Publication and shall agree to designate employees or others acting on behalf of the other Party as co-authors on any Publication describing results to which such persons have contributed in
accordance with standards applicable to authorship of scientific publications. If the other Party reasonably determines that the Publication would entail the public disclosure of such Party’s Confidential Information or of a patentable
invention upon which a patent application should be filed prior to any such disclosure, submission of the concerned Publication to Third Parties shall be delayed for such period as may be reasonably necessary for deleting any such Confidential
Information of the other Party (if the other Party has requested deletion thereof from the proposed Publication), or the drafting and filing of a patent application claiming such invention, provided such additional period shall not exceed [***] from

parenthetical, Confidential Information of the requesting Party arising out of a Program with respect to such Designated Target) to which such non-requesting Party does not retain rights under the
surviving provisions of this Agreement, each Party shall, upon and in accordance with the other Party’s request in writing, either: (a) promptly destroy all copies of such Confidential Information in the possession or control of the non-requesting Party and confirm such destruction in writing to the requesting Party; or (b) promptly deliver to the requesting Party, at the non-requesting Party’s
sole cost and expense, all copies of such Confidential Information in the possession or control of the non-requesting Party. Notwithstanding the foregoing, the
non-requesting Party shall be permitted to retain such Confidential Information (i) to the extent necessary or useful for purposes of performing any continuing obligations or exercising any ongoing rights

counsel of its choosing, shall have the sole right, but not the obligation, to defend against any Third Party Action in the Territory alleging that the Development, Manufacture, Commercialization or other Exploitation of any Licensed Product

IP under this Agreement), or the Exploitation thereof, infringes or misappropriates a Third Party’s intellectual property rights and Takeda obtains a license or other rights from such Third Party to such intellectual property rights, whether by
license, settlement, judgment or otherwise, Takeda shall be entitled to offset a total of up to [***] of the reasonable out-of-pocket costs and expenses of defending or
settling such Third Party Action under this Section 8.7.2 (including the payment of any damage awards, settlement amounts or other similar amounts payable to such Third Party), said offset in a given Calendar Quarter to be made

defended under this Section 8.7.2 shall be applied first to reimburse Takeda for its reasonable out-of-pocket costs and expenses of defending such claim, suit or
proceedings and then to reimburse MTEM for amounts deducted pursuant to the previous sentence, with the balance of any such recoveries being shared between the Parties [***] to Takeda and [***] to MTEM if Takeda is entitled to offset royalties at or
below the aforementioned limit under this Section 8.7.2, and otherwise, the balance of any such recoveries shall be retained by Takeda. Takeda shall have the sole and exclusive right to select counsel for such Third Party Action. MTEM shall
have the right to select its own counsel to represent MTEM and consult with Takeda’s selected counsel in any Third Party Action for which Takeda is entitled to offset any portion of its costs and expenses of any damage awards, settlement
amounts or other similar amounts payable to such Third Party.

obligation, to defend and control the defense of the validity and enforceability thereof), the Parties shall promptly meet to discuss in good faith the most favorable approach to defend against any such allegation in light of each Party’s
commercial interests therein, including which Party should control the defense of the validity and enforceability of the Program Patent Rights (other than with respect to any Program Patent Rights owned or Controlled by Takeda) or the MTEM
Background Patent Rights and the allocation of costs and expenses with respect thereto; provided, that as between the Parties, if any such invalidity or unenforceability of any such Program Patent Rights or MTEM Background Patent Rights is raised as
a defense or counterclaim in connection with a Third Party Action initiated pursuant to Section 8.7, Takeda

not to defend or control the defense of the applicable Patent Rights in a suit brought in the Territory or otherwise fails to initiate and maintain the defense of any such claim, suit or proceeding, then the other Party may conduct and control the
defense and settlement of any such claim, suit or proceeding using counsel of its own choice at its sole cost and expense. Where a Party controls such an action, the other Party shall have the right to participate in any such claim, suit or
proceeding with counsel of its choice at its sole cost and expense (provided, that the controlling Party shall retain control of the defense in such claim, suit or proceeding) and shall cause its Affiliates to, assist and cooperate with the
controlling Party, at the controlling Party’s expense, as such controlling Party may reasonably request from time to time in connection with its activities set forth in this Section. In connection with any activities with respect to a defense,

10.2.1 A Party (the “Indemnitee”) that intends to claim indemnification under this 0 shall promptly provide notice to
the other Party (the “Indemnitor”) of any Claim in respect of which the Indemnitee intends to claim such indemnification, which notice shall include a reasonable identification of the alleged facts giving rise to such Liability, and
the Indemnitor shall have the right to participate in, and, to the extent the Indemnitor so desires, jointly with any other Indemnitor similarly noticed, to control the defense thereof with counsel selected by the Indemnitor. However,
notwithstanding the foregoing, except with respect to any Claim that is a Third Party Action, the process for the defense of which shall be governed by Section 8.7, the Indemnitee shall have the right to participate in, but not control, the
defense of any Claim, and request separate counsel, with the fees and expenses to be paid by the Indemnitee, unless (a) representation of such Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or

it, without the prior written consent of the Indemnitee, which consent shall not be unreasonably withheld, conditioned or delayed. 

10.2.2 The assumption of the defense of a Claim by the Indemnitor shall not be construed as an acknowledgment that the Indemnitor is
liable to indemnify the Indemnitee in respect of the Claim, nor shall it constitute a waiver by the Indemnitor of any defenses it may assert against the Indemnitee’s claim for indemnification. In the event that it is ultimately determined that
the Indemnitor is not obligated to indemnify, defend or hold harmless the Indemnitee from and against the Claim, the Indemnitee shall reimburse the Indemnitor for any and all costs and expenses (including attorneys’ fees and costs of suit) and
any Liabilities incurred by the Indemnitor in its defense of the Claim.

respect to any alleged breach by Takeda of its diligence obligations set forth in Section 4.3, in which case, MTEM shall first provide written notice thereof to Takeda and the Parties shall meet within [***] after delivery of such notice to
Takeda to discuss in good faith such alleged breach and Takeda’s Development and Commercialization plans, as applicable, with respect to the applicable Licensed Product, which discussions shall be concluded before MTEM may issue any such
termination notice with respect to such alleged

breach; provided, that if either Party initiates a dispute resolution procedure under Section 12.3 as permitted under this Agreement to resolve the dispute for which termination is being
sought within [***] following the end of the Notice Period and is diligently pursuing such procedure, the Notice Period shall be tolled and the termination shall become effective only if such breach remains uncured for [***] after the final
resolution of the dispute through such dispute resolution procedure (or, if the breach cannot be cured within such [***] period, if the Breaching Party commences actions to cure such breach within such period and thereafter diligently continues such
actions). It is understood that termination pursuant to this Section 11.3 shall be a remedy of last resort and may be invoked only in the case where the breach cannot be reasonably remedied by the payment of money damages. During any cure
period under this Section 11.3.1 in response to a notice from Takeda, any obligation of Takeda to pay milestones under Article VI shall be suspended unless and until MTEM has cured the material breach at issue. 

11.3.2 Insolvency. Either Party may terminate this Agreement in its entirety effective immediately upon written notice to the
other Party if, at any time such other Party (a) files in any court or agency pursuant to any statute or regulation of any state or country a petition in bankruptcy or insolvency or for reorganization (save for solvent reorganization or solvent
reconstruction), (b) files for, appoints or suffers appointment of a receiver or trustee of the Party or over substantially all of its assets that is not discharged within [***] after such filing, (c) proposes a written agreement of composition
or extension of substantially all of its debts, (d) files a petition under any bankruptcy or insolvency act or has any such petition filed against that is not discharged within [***] of the filing thereof, (e) proposes or is a party to any
dissolution or liquidation, (f) admits in writing its inability generally to meet its obligations as they fall due in the general course or (g) makes an assignment of substantially all of its assets for the benefit of creditors. 

Section 11.4 License Survival Upon Insolvency. All licenses (and to the extent applicable, rights)
granted under or pursuant to this Agreement are, and shall otherwise be deemed to be, for purposes of Section 365(n) of 11 U.S.C. § 101, et. seq. (“Bankruptcy Code”), licenses of rights to “intellectual property”
as defined under the Paragraph 101(35A) of the Bankruptcy Code. The Parties agree that the non-bankrupt Party shall retain and may fully exercise all of its rights and elections under Applicable Law. The
Parties further agree that, in the event of the commencement of bankruptcy proceeding by or against a bankrupt Party, the other Party shall be entitled to a complete duplicate of (or complete access to, as appropriate) any intellectual property that
is licensed to such Party pursuant to the license grants set forth in Article III, but only to the extent set forth in such license grants, and all embodiments of such intellectual property; and the same, if not already in the other Party’s
possession, shall be promptly delivered to the other Party (a) upon any such commencement of a bankruptcy proceeding, upon the other Party’s written request therefor (which request must identify the specific intellectual property), unless
the bankrupt Party (or trustee on behalf of the bankrupt Party) elects within [***] to continue to perform all of its obligations under this Agreement or (b) if not delivered under (a) above, upon rejection of this Agreement by or on
behalf of the bankrupt Party, upon written request therefore by the other Party. 
 Section 11.5 Effect of
Expiration and Termination.  
 11.5.1 General Effects. Except where explicitly provided within this Agreement,
expiration or termination of this Agreement in its entirety or with respect to any Takeda Target, as applicable for any reason, will not affect any obligations, including payment of any royalties or other sums which have accrued as of the date of
termination or expiration. Notwithstanding the foregoing, but 

  
 Portions of this Exhibit,
indicated by the mark “[***],” were omitted and have been filed separately with the Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 24b-2 of the Securities
Exchange Act of 1934, as amended. 
 Page 63 








 
subject to Section 11.1, upon expiration or termination of this Agreement, MTEM’s obligations pursuant to Section 3.10 will [***] terminate (a) with respect to a Takeda Target
having been terminated, and (b) in full if this Agreement is terminated in its entirety. Following the delivery of a notice of termination of this Agreement in its entirety by a Party, Takeda shall not be responsible for the payment of any
future milestones under this Agreement other than those that were due prior to the delivery of the notice of termination. Except as needed in order to permit the sell-off activities set forth in
Section 11.5.2, upon expiration or termination of this Agreement in its entirety, all licenses granted by either Party to the other Party hereunder (other than pursuant to Section 3.2), including all Research Licenses and Exclusive
Licenses, and all sublicenses granted by either Party thereunder, will [***] terminate. In the event of a termination with respect to only one Takeda Target, only the licenses to the extent relating to such Takeda Target shall terminate. For
clarity, the Program with respect to the terminated Targets shall terminate effective upon receipt of notice of termination. Upon expiration or termination of this Agreement in its entirety or with respect to only one Takeda Target, the Parties will
agree upon and implement a plan for the orderly transition or winding down of any in-process Regulatory Filings or Clinical Trials in a manner consistent with Applicable Laws and standards of ethical conduct
of human clinical trials. 
 11.5.2 Sell-Off. In the case that the licenses granted to
Takeda under Section 3.1 or Section 3.4 terminate with respect to a Target, notwithstanding such termination, Takeda shall have the right to complete (or have completed) the Manufacture of any work-in-process SLT-A Fusion Proteins, Licensed Products or and sell any existing inventory of Licensed Product(s) (if applicable) with respect to the terminated Target
for a period of up to [***] following such termination, subject to Takeda’s obligation to make corresponding payments with respect to any such sales pursuant to Section 6.8. 

11.5.3 Effect of Termination by Takeda for Convenience. If Takeda terminates this Agreement in its entirety or with respect to
any Takeda Target pursuant to Section 11.2.1, all licenses granted pursuant to this Agreement (and then in effect) or all licenses relating to such Target (and then in effect), as applicable, shall automatically be terminated and MTEM shall
automatically have as of the termination effective date (“Termination Effective Date”), an option exercisable within [***] of the Termination Effective Date to obtain on reasonable commercial terms a worldwide, non-exclusive, sublicensable, royalty-bearing license under Takeda’s interest in Program IP generated, conceived or reduced to practice during the terminated Programs that (a) is not related to any Takeda
Targeting Moiety, and (b) was not derived from or generated, conceived or reduced to practice with the use of any Takeda Confidential Information, including any Takeda Background IP, for any and all uses. 

11.5.4 Effect of Termination by Takeda for Change in Control of MTEM. If Takeda terminates this Agreement in its entirety
pursuant to Section 11.2.1 prior to Takeda’s exercise of all Options hereunder, (a) all licenses granted pursuant to this Agreement (and then in effect) or all licenses relating to such Target (and then in effect), as applicable,
shall automatically be terminated (other than pursuant to Section 3.2), and (b) in the case of termination (or assumption of MTEM Program Activities) by Takeda pursuant to Section 11.2.2, within [***] following such election by
Takeda, MTEM shall reimburse Takeda for any amounts paid by Takeda pursuant to Section 6.1 or Section 6.3 with respect to any Takeda Target terminated or assumed by Takeda pursuant to Section 11.2.1. If Takeda terminates this
Agreement in its entirety or with respect to any Takeda Target pursuant to Section 11.2.2 after Takeda’s exercise of all Options hereunder, all licenses granted pursuant to this Agreement (and then in effect) or all licenses relating to
such Target (and then in effect), as applicable, shall survive and all licenses and remaining payment obligations, including payment of any royalties or other sums which have accrued as of the date of termination or expiration, will survive.

 11.5.5 Effect of Termination by MTEM for Material Breach or Takeda Insolvency. If
MTEM terminates this Agreement in its entirety pursuant to Section 11.3.1 or Section 11.3.2, all licenses granted pursuant to this Agreement (and then in effect) or all licenses relating to such Target (and then in effect), as applicable,
shall automatically be terminated and MTEM shall automatically have as of the Termination Effective Date, an option exercisable within [***] of the Termination Effective Date to obtain on reasonable commercial terms a worldwide, non-exclusive, sublicensable, royalty-bearing license under Takeda’s interest in Program IP generated, conceived or reduced to practice during the terminated Programs that (a) is not related to any Takeda
Targeting Moiety, and (b) was not derived from or generated, conceived or reduced to practice with the use of any Takeda Confidential Information, including any Takeda Background IP, for any and all uses. 

11.5.6 Effect of Termination by Takeda for Material Breach or for MTEM Insolvency. In the event that Takeda is entitled to
terminate this Agreement in its entirety pursuant to Section 11.3.1 or Section 11.3.2, Takeda may, as an alternative, elect to maintain this Agreement in effect, except that the first and second sentences of Section 4.4 shall
terminate. 
 11.5.7 Continuation in Lieu of Termination. If Takeda has the right to terminate any Target under
Section 11.3 but does not elect to exercise such right, this Agreement shall continue in full force and effect.  

11.5.8 Survival. The following provisions will survive expiration or termination of this Agreement: Articles I, VII, VIII, IX, X
and XII and Sections 2.2.3, 2.2.4, 2.2.5, 2.4, 3.2, 6.15, 6.16, 6.17, 11.4 and 11.5.

 Section 12.2 Applicable Law; Jurisdiction. This
Agreement shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts, without regard to the conflict of law principles thereof that may dictate application of the laws of any other jurisdiction. Subject to
Section 12.3, the Parties hereby irrevocably and unconditionally consent to the exclusive jurisdiction of the courts of the Commonwealth of Massachusetts for any action, suit or proceeding (other than appeals therefrom) arising out of or
relating to this Agreement. 
 Section 12.3 Dispute Resolution. The Parties agree that if any
dispute or disagreement arises between Takeda on the one hand and MTEM on the other in respect of this Agreement, subject to Section 12.12, they shall follow the following procedure in an attempt to resolve the dispute or disagreement. 

12.3.1 The Party claiming that such a dispute exists shall give notice in writing (“Notice of Dispute”) to the other
Party of the nature of the dispute. 
 12.3.2 Within [***] following receipt of a Notice of Dispute, the [***] of MTEM and the [***]
(or equivalent) of Takeda shall meet at a mutually agreed upon time and location for the purpose of resolving such dispute. 
 12.3.3
In the event of a dispute between the Parties requiring resolution by a panel of experts (“Expert Panel”), such dispute shall be resolved in accordance with this Section 12.3.3. Notice from a Party initiating resolution by the
Expert Panel shall contain a statement of the issue forming the basis of the dispute, the position of the moving Party as to the proper resolution of that issue and the basis for such position. Within [***] after receipt of such notice, the
responding Party shall submit to the moving Party a statement of its conception of the specific issue in question, its position as to the proper resolution of that issue and the basis for such position. 

(a) Within [***] of the responding Party’s response, each Party shall appoint to the Expert Panel an individual who (i) has
expertise in the pharmaceutical or biotechnology industry and the specific matters at issue, (ii) is not a current or former director, employee or consultant of such Party or any of its Affiliates, or otherwise has not received compensation or
other payments from such Party (or its Affiliates) for the past five (5) years and (iii) has no known personal financial interest or benefit in the outcome or resolution of the dispute, and the appointing Party shall give the other Party
written notice of such appointment; provided, that for such appointment to be effective and for such individual to serve on the Expert Panel, such individual must deliver to the other Party a certificate confirming that such individual satisfies the
criteria set forth in clauses (i) through (iii) above, disclosing any potential conflict or bias and certifying that, as a member of the Expert Panel, such individual is able to render an independent decision. Within [***] of the appointment of
the second expert, the two (2)-appointed experts shall agree on an additional expert who meets the same criteria as described above, and shall appoint such expert as chair of the Expert Panel. If the Party-appointed experts fail to timely agree on a
third expert, then upon the written request of either Party, each Party-appointed expert shall, within [***] of such request, nominate one expert candidate and the CPR Institute for Dispute Resolution shall, within [***] of receiving the names of
the Parties’ respective nominees, select one of those experts to serve as the chair of the Expert Panel. Each expert shall agree, prior to his or her appointment, to render a decision as soon as practicable after the appointment of the full
Expert Panel.

Exchange Act of 1934, as amended. 
 Page 66 








 (b) Within [***] of the appointment of the third expert, the Expert Panel shall hold a
preliminary meeting or teleconference with the Parties or their representatives and shall designate a time and place for a hearing of the Parties on the dispute and the procedures to be utilized at the hearing. The Parties may agree in writing to
waive the hearing and have the Expert Panel reach a decision on the basis of written submissions alone. The Expert Panel may order the Parties to produce any documents or information that are relevant to the dispute. All such documents or
information shall be provided to the other Party and the Expert Panel as expeditiously as possible but no later than [***] prior to the hearing (if any), along with the names of all witnesses who will testify at the hearing and a brief summary of
their testimony. The hearing shall be held in Boston, MA, unless otherwise agreed by the Parties, and shall take place as soon as possible but no more than [***] after the appointment of the third expert, unless the Parties otherwise agree in
writing or the Expert Panel agrees to extend such time period for good cause shown. The hearing shall last no more than one (1) day, unless otherwise agreed by the Parties or the Expert Panel agrees to extend such time period for good cause
shown. After the conclusion of all testimony (or if no hearing is held after all submissions have been received from the Parties), at a time designated by the Expert Panel no later than [***] after the close of the hearing or the receipt of all
submissions, each Party shall simultaneously submit to the Expert Panel and exchange with the other Party its final proposed resolution. 

(c) In rendering the final decision (which shall be rendered no later than fifteen (15) days after receipt by the Expert Panel of
the Parties’ respective proposed resolutions), the Expert Panel shall be limited to choosing a resolution proposed by a Party without modification; provided, that in no event shall the Expert Panel render a decision that is inconsistent with
the Parties’ intentions as set forth in this Agreement. The agreement of two (2) of the three (3) experts shall be sufficient to render a decision and the Parties shall abide by such decision. The decision of the Expert Panel shall be
final and binding on the Parties and may be entered and enforced in any court having jurisdiction. The Parties shall share equally the costs and expenses of the Expert Panel. 

12.3.4 In the event of an unresolved dispute between the Parties involving intellectual property, including any disputes relating to
inventorship or the validity, enforceability or scope of any patent or trademark rights shall, but other than as set forth in Section 12.3.3, such dispute shall, at either Party’s election and subject to Section 12.2, be submitted for
resolution by a court of competent jurisdiction. 
 12.3.5 In the event of a dispute regarding any payments owing under this
Agreement, all undisputed amounts shall be paid promptly when due and the balance, if any, promptly after resolution of the dispute. 

Section 12.4 Entire Agreement. This Agreement, together with the Exhibits and Schedules attached
hereto and the Quality Agreement, contains the entire understanding of the Parties with respect to the specific subject matter hereof. All express or implied agreements and understandings, either oral or written, heretofore made are expressly
superseded by this Agreement, including that certain Confidential Disclosure Agreement between the Parties dated December 17, 2015, as amended by letter agreement Amendment 1, dated October 21, 2016, which is hereby terminated effective as
of the Effective Date; provided, that such Confidential Disclosure Agreement will continue to govern the treatment of Confidential Information (as defined therein) disclosed by the Parties prior to the Effective Date in accordance with its terms.
This Agreement may be amended, or any term hereof modified, only by a written instrument duly executed by both Parties. 

Section 12.5 Severability. Each Party hereby agrees that it does not intend to violate any public
policy, statutory or common laws, rules, regulations, treaty or decision of any government agency or executive body thereof of any country or community or association of countries. Should one or more provisions of this Agreement be or become
invalid, the Parties shall substitute, by mutual consent, valid provisions for such invalid provisions, in their economic effect, are sufficiently similar to the invalid

provisions that it can be reasonably assumed that the Parties would have entered into this Agreement based on such valid provisions. In case such alternative provisions cannot be agreed upon, the
invalidity of one or several provisions of this Agreement shall not affect the validity of this Agreement as a whole, unless the invalid provisions are of such essential importance to this Agreement that it is to be reasonably assumed that the
Parties would not have entered into this Agreement without the invalid provisions. 
 Section 12.6 Force
Majeure. No Party (or any of its Affiliates) shall be held liable or responsible to the other Party (or any of its Affiliates) hereunder, or be deemed to have defaulted under or breached this Agreement, for failure or delay by such Party in
fulfilling or performing any term of this Agreement when such failure or delay is caused by or results from causes beyond the reasonable control of the affected Party (or any of its Affiliates), including fire, floods, embargoes, war, acts of war
(whether war be declared or not), insurrections, riots, civil commotions, acts of God, earthquakes, or omissions or delays in acting by any Governmental Authority (each, an “Event of Force Majeure”); provided, that the affected
Party shall exert all reasonable efforts to eliminate, cure or overcome any such Event of Force Majeure and to resume performance of its obligations promptly. Notwithstanding the foregoing, to the extent that an Event of Force Majeure continues for
a period in excess of six (6) months, the affected Party shall promptly notify in writing the other Party of such Event of Force Majeure and within four (4) months of the other Party’s receipt of such notice, the Parties shall negotiate in good
faith either (a) a resolution of the Event of Force Majeure, if possible or (b) an extension by mutual agreement of the time period to resolve, eliminate, cure or overcome such Event of Force Majeure. 

Section 12.7 Assignment. Neither Party may assign its rights or, except as provided in
Section 2.2.5 and Article VIII, delegate its obligations under this Agreement, whether by operation of law or otherwise, in whole or in part (including with respect to any Licensed Target or any Licensed Product) without the prior written
consent of the other Party, which consent shall not be unreasonably withheld, conditioned or delayed, except that Takeda shall have the right, without such consent, (a) to perform any or all of its obligations and exercise any or all of its
rights under this Agreement through any of its Affiliates, Sublicensees or Distributors, and (b) assign any or all of its rights and delegate any or all of its obligations hereunder (including on a Target-by- Target or Licensed Product-by-Licensed Product basis) to any of its Affiliates or its or their Sublicensees or to any
successor in interest (whether by merger, acquisition, asset purchase or otherwise) to all or substantially all of the business to which this Agreement (or the applicable Licensed Target(s) or Licensed Product(s)) relates); provided that Takeda
shall provide written notice to MTEM within thirty (30) days after such assignment or delegation. Any permitted successor of Takeda or any permitted assignee of all of a Takeda’s rights under this Agreement that has also assumed all of
Takeda’s obligations hereunder in writing shall, upon any such succession or assignment and assumption, be deemed to be a party to this Agreement as though named herein in substitution for Takeda, whereupon Takeda shall cease to be a party to
this Agreement and shall cease to have any rights or obligations under this Agreement. All validly assigned rights of Takeda shall inure to the benefit of and be enforceable by, and all validly delegated obligations of Takeda shall be binding on and
be enforceable against, the permitted successors and assigns of Takeda. Any attempted assignment or delegation in violation of this Section 12.7 shall be void and of no effect. 

Section 12.8 Independent Contractors. MTEM and Takeda each acknowledge that they shall be independent
contractors and that the relationship between the Parties shall not constitute a partnership, joint venture, agency or any type of fiduciary relationship. Neither MTEM nor Takeda shall have the authority to make any statements, representations or
commitments of any kind, or to take any action, which shall be binding on the other Party, without the prior consent of the other Party to do so.

Exchange Act of 1934, as amended.

 Section 12.9 Waiver and
Non-Exclusion of Remedies. The waiver by either Party of any right hereunder or the failure to perform or of a breach by the other Party shall not be deemed a waiver of any other right hereunder or of
any other breach or failure by said other Party whether of a similar nature or otherwise. The rights and remedies provided herein are cumulative and do not exclude any other right or remedy provided by Applicable Law or otherwise available, except
as expressly set forth herein. 
 Section 12.10 Further Assurances. Each Party shall execute
such additional documents as are necessary to effect the purposes of this Agreement. 
 Section 12.11
No Benefit to Third Parties. Except as provided in Article X, the covenants and agreements set forth in this Agreement are for the sole benefit of the Parties hereto and their successors and permitted assigns and they shall not
be construed as conferring any rights on any other parties. 
 Section 12.12 Equitable
Relief. Each Party acknowledges and agrees that the restrictions set forth in Section 2.5.4(c), Section 3.10, Article VII and Article VIII are reasonable and necessary to protect the legitimate interests of the other Party and that
such other Party would not have entered into this Agreement in the absence of such restrictions and that any breach or threatened breach of any provision of such Section or Articles may result in irreparable injury to such other Party for which
there will be no adequate remedy at law. In the event of a breach or threatened breach of any provision of such Section or Articles, the non-breaching Party shall be authorized and entitled to seek from any
court of competent jurisdiction injunctive relief, whether preliminary or permanent, specific performance and an equitable accounting of all earnings, profits and other benefits arising from such breach, which rights shall be cumulative and in
addition to any other rights or remedies to which such non-breaching Party may be entitled in law or equity. Both Parties agree to waive any requirement that the other (a) post a bond or other security as
a condition for obtaining any such relief and (b) show irreparable harm, balancing of harms, consideration of the public interest or inadequacy of monetary damages as a remedy. Nothing in this Section 12.12 is intended or should be
construed, to limit either Party’s right to equitable relief or any other remedy for a breach of any other provision of this Agreement. 

Section 12.13 Counterparts. This Agreement may be executed in two or more counterparts,
each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Counterparts may be signed or delivered by facsimile or electronically scanned signature page.
