 This Consulting and Severance Agreement (the “Agreement”) is entered into as of August 22, 2005 (the “Effective Date”)
by and between Seattle Genetics, Inc. (the “Company”) and Tim J. Carroll (“Consultant”). 
  
 WHEREAS, Consultant has been employed as the Company’s Chief Financial Officer; 
  
 WHEREAS, the Company and Consultant have mutually agreed to terminate Consultant’s employment relationship and to begin
a consulting relationship on the terms set forth below; 
  
 NOW,
THEREFORE, in consideration of the mutual promises made herein, the receipt and sufficiency of which are hereby acknowledged, the Company and Consultant hereby agree as follows: 
  
 1. Termination of Employment and Consulting Relationship. The effective date of the termination of
Consultant’s employment with the Company shall be October 3, 2005 (the “Termination Date”). Consultant shall, until otherwise directed by the Company, continue to perform all of his regular job duties and responsibilities for
the Company through the Termination Date and continue to comply with all Company policies and procedures. The Company shall pay to Consultant all salary, wages, accrued and unused vacation through the Termination Date and any and all other benefits
due to Consultant with respect to his employment, except bonus payments to Consultant which are provided for in Section 2 below. Beginning October 4, 2005, in consideration for the release of claims set forth in Section 4 below and other obligations
and benefits under this Agreement, Consultant will provide consulting services (the “Services”) at a full-time capacity for three (3) months through January 3, 2006 and then at half-time capacity for one (1) month from January 4,
2006 through February 3, 2006 as set forth in Section 3 of this Agreement. 
  
 2. Consideration. In consideration for the release of claims set forth in Section 4 below and other obligations under this Agreement, including the provision of the Services during the periods set forth
above, and provided that Consultant does not revoke his execution of this Agreement during the Revocation Period described in Section 5 below, the Company agrees to provide to Consultant the following benefits following the Termination Date: (a) the
Company will enter into a consulting arrangement with Consultant under the terms and conditions set forth in Section 3 below; (b) continued health insurance benefits (through COBRA) from the Termination Date through May 30, 2006; and (c) the bonus
normally payable to Consultant as if Consultant worked full-time during 2005, using an earned rate of one hundred percent (100%) at the thirty percent (30%) threshold for the Chief Financial Officer position with such bonus paid at the same time as
the Company pays bonuses to the other executives in the Company. 
  
 3. Consulting Arrangement. 
  
 (a)
Fees and Options. As consideration for the Services to be provided by Consultant and other obligations, the Company will compensate Consultant at the rate of $19,066.68 per month during the three (3) month period that Services are
provided on a full-time basis from October 4, 2005 through January 3, 2006, and at the rate of $9,533.34 per month during the one (1) month period that Services are provided on a half-time basis from January 4, 2006 through February 3, 2006. In
addition, Consultant’s options for the Company’s common stock outstanding at the date of this Agreement shall continue to vest during Consultant’s performance of Services in accordance with the terms of the Company’s 1998 Stock
Option Plan and Consultant’s stock option agreements.  







 (b) Expenses. Effective as of October 3, 2005, Consultant shall not be authorized to incur
on behalf of the Company any expenses exceeding $1,500.00 without the prior written consent of the Company’s President and Chief Executive Officer. As a condition to receipt of reimbursement, Consultant shall be required to submit to the
Company reasonable evidence that the amount involved was expended and related to Services provided under this Agreement. 
  
 (c) Term. Consultant shall serve as a consultant to the Company on an “at will” basis from October 4, 2005 through February 3,
2006. 
  
 (d) Independent Contractor.
Consultant’s relationship with the Company beginning October 4, 2005 will be that of an independent contractor and not that of an employee. Consultant will not be eligible for any employee benefits except as set forth in this Agreement, nor
will the Company make deductions for taxes from consulting fee payments made to Consultant pursuant to this Section 3, which will be Consultant’s responsibility. Consultant agrees to indemnify and hold the Company harmless from any liability
for, or assessment of, any such taxes imposed on the Company by relevant taxing authorities. Consultant will have no authority to enter into contracts that bind the Company or create obligations on the part of the Company without the prior written
authorization of the Company. 
  
 (e) Supervision of
Consultant’s Services. All services to be performed by Consultant, including but not limited to the Services, will be as agreed between Consultant and the Company’s President and Chief Executive Officer. Consultant shall use
Consultant’s best efforts to perform the Services in a manner satisfactory to the Company. 
  
 (f) Conflicts with this Agreement. Consultant represents and warrants that he is not under any pre-existing obligation in conflict or in any
way inconsistent with the provisions of this Agreement. Consultant warrants that Consultant has the right to disclose or use all ideas, processes, techniques and other information, if any, which Consultant has gained from third parties, and which
Consultant discloses to the Company in the course of performance of this Agreement, without liability to such third parties. Consultant represents and warrants that Consultant has not granted any rights or licenses to any intellectual property or
technology that would conflict with Consultant’s obligations under this Agreement. Consultant will not knowingly infringe upon any copyright, patent, trade secret or other property right of any former client, employer or third party in the
performance of the services required by this Agreement. 
  
 4.
Release of Claims. In exchange for the consideration provided under this Agreement, Consultant and his successors and assigns hereby fully and forever release and discharge the Company, any of its subsidiaries or related companies, any
Company-sponsored employee benefit plan in which Consultant participates and any of their officers, directors, trustees, stockholders, agents, employees, investors, stockholders, administrators, and their successors and assigns from any claim, duty,
obligation or cause of action relating to any matters of any kind, whether known or unknown, suspected or unsuspected, that Consultant may possess arising from any omissions, acts or facts that have occurred up until and including the date of this
Agreement, including, without limitation: 
  
 (a) any and all
claims relating to or arising from Consultant’s employment relationship with the Company and termination of that relationship; 
  
 (b) any and all claims relating to, or arising from, Consultant’s right to purchase, or actual purchase of shares of stock of the Company;

  
 (c) any and all claims for personal injury, wrongful discharge
of employment, breach of contract (both express and implied), breach of a covenant of good faith and fair dealing (both express and implied), negligent or intentional infliction of emotional distress, negligent or intentional misrepresentation,
negligent or intentional interference with contract or prospective economic advantage and defamation;

below, and/or the bylaws or certificate of incorporation of the Company as a former officer of the Company. Consultant and the Company agree that the release set forth in this Section 4 shall be and shall remain in effect as a complete general
release as to the matters released. This release does not extend to any obligations incurred under this Agreement or to any rights or claims that may arise after the Effective Date. 
  
 5. Acknowledgement of Waiver of Claims under ADEA. Consultant acknowledges that he is waiving and releasing
any rights he may have under the Age Discrimination in Employment Act of 1967 (“ADEA”) and that this waiver and release is knowing and voluntary. Consultant and the Company agree that this waiver and release does not apply to any

agreement shall remain in effect pursuant to its terms.

with the terms of such Indemnification Agreement. The Company will provide Consultant indemnification pursuant to the Indemnification Agreement and the Company’s certificate of incorporation and bylaws, to the fullest extent authorized or
permitted by law. The Company further agrees that with respect to the period of time in which Consultant was an officer of the Company, Consultant shall continue to be covered by any director and officer insurance policies that the Company may have
in place from time to time in accordance with Section 7 of the Indemnification Agreement.
