NOW, THEREFORE, the parties agree as follows:




All references to particular Exhibits, Articles and Sections shall mean the Exhibits to, and Articles and Sections of, this Agreement, unless otherwise specified. For the purposes of this Agreement the following words and phrases shall have the following meanings:


1.1 "Affiliate" means, with respect to a party hereto, any corporate or other entity which, directly or indirectly, controls, is controlled by, or is under common control with such party during the term of this Agreement, where "control" means the ownership of not less than fifty percent (50%) of the voting shares of a corporation, or decision-making authority as to an unincorporated entity, provided that such entity shall be an Affiliate only so long as such control exists.


1.2 "Antibody" means any antibody directed against an Antigen and shall include, without limitation, monospecific and bispecific antibodies (but a separate license shall be required for each Antigen targeted by a bispecific antibody); less than full-length antibody forms such as Fv, Fab, Fab' and F(ab')2; single-chain antibodies; and antibody conjugates bound to a toxin, label or other moiety.

1.3 "Antigen" means a target molecule to which an Antibody specifically binds and includes all epitopes on that target molecule.


1.4 "Licensed Product" means an Antibody with respect to which Seattle Genetics has either significant marketing rights or has expended development effort (including without limitation created and/or humanized the Antibody or conducted preclinical or clinical development), the manufacture, import, use, offer to sell or sale of which would infringe, if not licensed under this Agreement, a Valid Claim.


1.5 "PDL License Agreement" means the form of PDL License Agreement attached as Exhibit B.


1.6 "PDL Patent Rights" means the patent applications or patents (as well as any foreign counterparts thereto) identified on Exhibit A, including any additions, continuations, continuations-in-part or divisions thereof or any substitute applications therefore; any patents issued with respect to such patent applications, any reissues, extensions or patent term extensions of any such patent, and any confirmation patents or registration patents or patents of addition based on any such patents.


1.7 [*]


1.8 "Valid Claim" means a claim of an issued and unexpired patent included in Licensed PDL Patents which has not been held permanently revoked, unenforceable or invalid by a decision of a court or other governmental agency of competent jurisdiction, unappealable or unappealed within the time allowed for appeal, and which has not been admitted to be invalid or unenforceable through reissue or disclaimer or otherwise.




Subject to the terms of this Agreement, PDL hereby grants Seattle Genetics during the term of this Agreement a non-exclusive, worldwide, non-transferable, royalty-free license (without the right to sublicense) for internal use under the PDL Patent Rights to conduct research and development activities with respect to Antibodies that bind to any Antigen (except as excluded below) for the development, identification, analysis, research, manufacture, characterization and preclinical development of such Antibody, and to conduct clinical trials up to, but excluding, [*] on such Antibodies ("Research License"); provided, however, that the Research License shall not include any rights under the PDL Patent Rights with respect to any Antibodies binding to the [*].


[*] Confidential treatment has been requested with respect to the omitted portions.





3.1 Election. Subject to the terms and conditions of this Agreement, PDL hereby grants to Seattle Genetics through the [*] anniversary of the Effective Date (or until such earlier time as Seattle Genetics has exercised its rights under this Section 3.1 with respect to [*] Antigens), the right upon written notice to receive licenses for Licensed Products under the PDL Patent Rights for up to [*] Antigens designated by Seattle Genetics. Each license shall be a nonexclusive, worldwide license under the PDL Patent Rights to make, have made, use, import, market, promote, offer for sale and sell or otherwise dispose of Licensed Products pursuant to a PDL License Agreement.


3.2 Procedure for Exercise of License Rights. Seattle Genetics shall provide PDL with a written notice identifying the Antigen for which Seattle Genetics desires to enter into a PDL License Agreement pursuant to the provisions of Section 3.1. A separate notice shall be provided with respect to each Antigen for which a license is requested. PDL shall promptly review and respond in writing to the request by Seattle Genetics for a license within ten (10) business days of receipt of the written request. PDL may refuse to grant Seattle Genetics a license only if PDL has previously granted an exclusive or co-exclusive license or an unexpired option for an exclusive or co-exclusive license with respect to an Antibody to the Antigen, can demonstrate that it is then actively engaged in bona fide negotiations for such an exclusive or co-exclusive license or option for an exclusive or co-exclusive license, or then has development, marketing or co-promotion rights, or an option to obtain such rights, to a product or a potential product directed against the Antigen. In the event that PDL validly refuses to grant Seattle Genetics a license under the PDL Patent Rights, Seattle Genetics' right under Section 3.1 shall not be considered exercised. If PDL affirms Seattle Genetics' request or has not responded by notice in writing within ten (10) business days of receipt of Seattle Genetics' request under this Section 3.2, then Seattle Genetics' election shall be deemed irrevocable and Seattle Genetics and PDL shall enter into a PDL License Agreement with respect to that Antigen, and Seattle Genetics shall pay the License Exercise Fee specified in Section 4.2.




4.1 License Exercise Fees. Within ten (10) business days after the Effective Date of a PDL License Agreement for a nonexclusive license for Antibodies for each of the [*] Antigens under section 3.1, Seattle Genetics shall pay to PDL an exercise fee ("License Exercise Fee") of [*] provided that such amount shall be increased annually beginning [*] and on each January 1 thereafter by an amount equal to the [*]. All adjustments hereunder shall be payable within fifteen (15) days of the publication of the [*] for the applicable year.




5.1 Valid Agreement. Each party represents and warrants to the other that it knows of no legal reason to prevent it from entering into this Agreement and that the signatory hereto is duly authorized to execute and deliver this Agreement.


5.2 Current PDL Patent Rights. The PDL Patent Rights constitute all of the patents and patent applications owned by PDL as of the Effective Date that relate generally to the humanization of antibodies.


[*] Confidential treatment has been requested with respect to the omitted portions.



5.3 No Warranty of Validity, Non-Infringement. Nothing in this Agreement shall be construed as (a) a warranty or representation by PDL as to the validity or scope of any PDL Patent Rights; or (b) a warranty or representation by PDL that any Antibody made, used, sold or otherwise disposed of under any PDL License Agreement is or will be free from infringement of patents, copyrights, trademarks, trade secrets or other rights of third parties.




5.5 Indemnification. Except to the extent attributable to PDL's gross negligence, willful misconduct or breach of any of its covenants, representations or warranties under this Agreement, Seattle Genetics shall at all times, during the term of this Agreement and thereafter, indemnify and hold harmless PDL and its Affiliates, sublicensees, directors, officers, agents and employees from any claim, proceeding, loss, expense, and liability of any kind whatsoever (including but not limited to those resulting from death, personal injury, illness or property damage and including legal expenses and reasonable attorneys' fees) (each a "Liability") arising out of or resulting from (a) any claim of patent infringement (direct or contributory) or inducing patent infringement with respect to the activities of Seattle Genetics or its Affiliates or sublicensees and (b) the development, manufacture, holding, use, testing, advertisement, sale or other disposition by Seattle Genetics, its Affiliates or sublicensees, or any distributor, customer or representative thereof or any one in privity therewith, of any Licensed Product.


5.6 Procedure for Indemnification. PDL (the "Indemnitee") shall promptly provide notice to Seattle Genetics (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 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 assume the defense thereof with counsel selected by the Indemnitor; provided, however, that 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 reimbursed, indemnified, defended or held harmless under Section 5.5 shall be subject to prior consent of such Indemnitee, such consent shall be withheld unreasonably.
