Item 1.01

Entry into a Material Definitive Agreement.

On May 9, 2011, Seattle Genetics, Inc. (the “Company”) entered into a Lease, dated May 9, 2011, with WCM Highlands II, LLC, for approximately 81,000 square feet of office space in a building at 21717 30^th Drive SE, Bothell, WA 98021 (the “21717 Lease”). The Company intends to use the additional space to expand its operations and business. The term of the 21717 Lease runs for 84 months, commencing on July 1, 2011 (the “Commencement Date”). The approximate aggregate base rent due over the initial term of the 21717 Lease is $7,684,875. Subject to certain conditions, the Company has two (2) options to extend the 21717 Lease for a period of five (5) years each.

Also on May 9, 2011, the Company entered into a Third Amendment to Lease with B&N 141-302, LLC with respect to the Company’s current office space at 21823 30^th Drive SE, Bothell, WA (the “Amendment,” and as amended, the “21823 Lease”). The original 21823 Lease, dated as of December 1, 2000, was previously filed as an exhibit to the Company’s registration statement on Form S-1, filed on November 20, 2000. The Amendment removes certain of the Company’s rights to terminate the 21823 Lease earlier than the end of the current term.

The foregoing description of the 21717 Lease and the Amendment does not purport to be complete and is qualified in its entirety by the terms and conditions of the 21717 Lease and the Amendment, which will be filed as exhibits to the Company’s quarterly report on Form 10-Q for the period ending June 30, 2011.
