attorneys’ fees and costs, (collectively, the “Liabilities”) resulting from all Third Party claims, suits, actions, terminations or demands (collectively, the “Claims”) that are incurred, relate to or arise out
of (a) the inaccuracy of any representation or warranty made by such Party in this Agreement), or (b) the gross negligence, recklessness, unlawful acts or willful misconduct of the indemnifying Party in connection with the performance of its
obligations hereunder. 
  
 14.1.2 Licensee
shall defend, indemnify and hold harmless SGI Indemnitees from and against all Liabilities resulting from all Claims that are incurred, relate to or arise out of the development, manufacture or commercialization of Licensed Products by Licensee, its
Affiliates or Sublicensees, including any failure to test for or provide adequate warnings of adverse side effects, or any manufacturing defect in any Licensed Product; except in each case to the extent such Liabilities resulted from the gross

 14.1.3 SGI shall defend, indemnify and hold
harmless Licensee Indemnitees from and against all Liabilities resulting from all Claims that are incurred, relate to or arise out of any claims of infringement of Third Party rights arising out of the use of SGI Technology to research, develop,

any representation or warranty made by Licensee in this Agreement or any other action for which Licensee must indemnify SGI under Section 14.1.2.

Indemnitee (the “Indemnitee”) that intends to claim indemnification under this Article 14 shall promptly provide notice to the other Party (the “Indemnitor”) of any Liability or action 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 shall reasonably cooperate with all reasonable requests of the Indemnifying Party with
respect thereto. The Indemnitor shall, jointly with any other Indemnitor similarly noticed, assume the defense thereof, at the sole cost of the Indemnitor, with counsel selected by the Indemnitor. However, notwithstanding the foregoing, the
Indemnitee shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnitor, if representation of such Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential
differing interests between such Indemnitee and any other Party represented by such counsel in such proceedings. Any settlement of a Liability for which any Indemnitee seeks to be indemnified, defended or held harmless under this Article 14 that
could adversely affect the Indemnitee shall be subject to prior consent of such Indemnitee, provided that such consent shall not be withheld unreasonably. The Indemnitee may not settle any such claim, demand, action or other proceeding or otherwise
consent to an adverse judgment in any such action or other proceeding or make any admission as to liability or fault without the express written permission of the Indemnifying Party, which shall not be unreasonably withheld.

earthquakes, or omissions or delays in acting by any governmental authority (collectively, “Events of Force Majeure”); provided, however, 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 covenants promptly. Notwithstanding the foregoing, to the extent that an Event of Force Majeure continues for a period in excess of [***], the affected Party shall
promptly notify in writing the other Party of such Event of Force Majeure and within [***] 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, (b) an extension by mutual agreement of the time period to resolve, eliminate, cure or overcome such Event of Force Majeure, (c) an amendment of this Agreement to the extent reasonably possible, or (d) an early termination of this
Agreement.

 ARTICLE 17 - 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 hereto 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

 MANUFACTURING AND SUPPLY AGREEMENT 
  
 THIS AGREEMENT is made and entered into as of the 4th day of May, 2005 (the “Effective Date”), by and
between Seattle Genetics, Inc., a Delaware corporation (“SGI”), having its principal place of business at 21823 30th Drive S.E., Bothell, WA 98021, and Organichem Corporation, a Delaware corporation (“Supplier”), having its principal place of business at 33 Riverside Avenue, Rensselaer, NY 12144. 
  
 RECITALS 
  
 WHEREAS, Supplier is in the business of manufacturing and testing pharmaceutical products; 
  
 WHEREAS, SGI is conducting preclinical development and potentially may
conduct clinical trials, and requires manufacture of auristatin drug-linkers such as vcMMAE, vcMMAF and mcMMAF (collectively, “Products”) to support such pre-clinical development and potential clinical trials; 
  
 WHEREAS, SGI wishes to purchase Products from Supplier for preclinical
development and potential clinical trials; 
  
 WHEREAS, Supplier
is willing to supply SGI with Products; and 
  
 WHEREAS, the
parties contemplate that Supplier may continue to supply SGI with commercial quantities of Products in the event marketing approval is obtained, in which case the parties shall negotiate appropriate amendments to this Agreement and/or a new
commercial supply agreement; 
  
 NOW, THEREFORE, in consideration
of the mutual promises and covenants set forth below, SGI and Supplier mutually agree as follows: 
  

	1.	PURCHASE AND SUPPLY. 

  
 1.1 Purchase and Supply Agreement. During the term of this Agreement, SGI agrees to buy, and Supplier agrees to sell, such quantities of Products
at such prices as may be set forth on Project Plans placed by SGI in accordance with the provisions of Section 1.2 and accepted by Supplier, which shall be attached hereto in sequential order as Exhibit A-1, Exhibit A-2 and so on
(“Project Plans”). 
  
 1.2 Ordering. Any
Project Plans submitted by SGI shall reference this Agreement and shall be governed exclusively by the terms contained herein. Any term or condition in any order, confirmation or other document furnished by SGI or Supplier which is in any way
inconsistent with these terms and conditions is hereby expressly rejected.

each Project Plan (as amended from time to time by written agreement between the parties) and such conformance will be verified in accordance with the testing standards and procedures specified therein. The parties acknowledge that the raw material
specifications and testing procedure set forth in a Project Plan may need to be refined and modified as the parties gain experience with the manufacture, testing and use of a Product. Accordingly, the parties agree to negotiate in good faith to
modify Project Plans from time to time as the parties gain experience with the manufacture, testing and use of a Product, and Supplier further agrees that it will use commercially reasonable efforts to facilitate changes to Project Plans that are
necessary or appropriate in light of FDA or other regulatory requirements. Supplier shall [***]. 
  
 1.6 Commercial Quantities: Binding Orders and Forecasts. The parties recognize that the potential market for Products will depend on a variety of
factors and that SGI is not presently able to provide forecasts of its future orders. Accordingly, each party [***].
