and Seattle Genetics, Inc., a corporation duly organized and existing under the laws of the State of Delaware, having offices at 22215 26th Avenue, SE, Bothell, Washington 98021 (“SGI”). 

PRELIMINARY STATEMENTS 
 A. BMS has developed, is the owner of and has all right, title and interest in and to certain valuable technology, including know-how and patents or patent applications, for the treatment of diseases and
conditions in humans. 
 B. In addition, BMS has obtained licenses with respect to certain other valuable technology, including
know-how and patents or patent applications, for the treatment of diseases and conditions in humans by entering into: (i) that certain Agreement with the University of Washington (the “Washington Agreement”), dated as of
January 26, 1989; (ii) that certain License Agreement, with Ixsys, Inc. (the “Ixsys Agreement”), dated as of June 8, 1993; and (iii) that certain Semi-Exclusive License Agreement with Enzon, Inc. (the “Enzon
Agreement”), dated as of September 30, 1993. 
 C. SGI is interested in developing and commercializing such technology
and desires to obtain a license from BMS to manufacture, market and sell products using such technology in the Territory. 
 D.
BMS is willing to grant such license to SGI on the terms and conditions set forth in this Agreement. 
 NOW, THEREFORE, in
consideration of the foregoing Preliminary Statements and the mutual covenants and agreements of the Parties contained in this Agreement, the Parties agree as follows:

(ii) freight, postage, shipping, insurance and transportation expenses and similar charges (in each instance, if separately identified in such invoice); (iii) credits or refunds actually allowed for rejections, defects or recalls of such
Product, outdated or returned Product, or because of rebates or retroactive price reductions; and (iv) sales, value-added, excise taxes, tariffs and duties, and other taxes directly related to the sale, to the extent that such items are
included in the gross invoice price (but not including taxes assessed against the income derived from such sale). Such amounts shall be determined from the books and records of SGI, its Affiliates or its sublicensees, maintained in accordance with
the reasonable accounting principles used by such entity, consistently applied. 
 In the event that a Product is sold as part
of a Combination Product (as defined below), the Net Sales from the Combination Product, for the purposes of determining royalty payments, shall be determined by multiplying the Net Sales of the Combination Product (calculated using the standard Net
Sales definition) during the applicable royalty reporting period by the fraction A/A+B, where A is the average sale price of the Product when sold separately in finished form and B is the average sale price of the other product(s) included in the
Combination Product when sold separately in finished form, in each case during the applicable royalty reporting period or, if sales of both the Product and the other product(s) did not occur in such period, then in the most recent royalty reporting
period in which sales of both occurred. In the event that such average sale price cannot be determined for both the Product and all other product(s) included in the Combination Product, Net Sales for the purposes of determining royalty payments
shall be calculated by multiplying the Net Sales of the Combination Product (calculated using the 

  
 -3-

 
standard Net Sales definition) by the fraction C/C+D, where C is the fair market value of the Product and D is the fair market value of all other pharmaceutical product(s) included in the
Combination Product. In such event, SGI shall in good faith make a determination of the respective fair market values of the Product and all other pharmaceutical products included in the Combination Product, and shall notify BMS of such
determination and provide BMS with data to support such determination. BMS shall have the right to review such determination and supporting data, and to notify SGI if it disagrees with such determination. 

As used above, the term “Combination Product” shall mean any pharmaceutical product which comprises the Product and any other
active compounds and/or ingredients. 
 1.20 “Party” shall mean BMS or SGI and, when used in the plural, shall
mean BMS and SGI. 
 1.21 “Patents” shall mean all patents and patent applications throughout the Territory,
and any substitutions, extensions, renewals, continuations, continuations-in-part, divisions, patents-of-addition and/or reissues or extensions thereof, which (i) are at present owned or controlled by BMS and are set forth in Exhibit A,
or (ii) are owned or controlled by SGI or jointly by BMS and SGI, as the case may be, and cover any Improvement. 
 1.22
“Person” shall mean any natural person, corporation, firm, business trust, joint venture, association, organization, company, partnership or other business entity, or any government or any agency or political subdivision thereof.

 1.23 “Product” shall mean any pharmaceutical formulation developed by SGI, its Affiliates or sublicensees
during the term of this Agreement, the manufacture, use or sale of which is either: (i) based upon or derived from any of the Know-How; or (ii) covered by one or more Patents and, but for this Agreement, would constitute an infringement of
a Valid Claim thereof. “Product” shall include Residual Product. 
 1.24 “Research Program” shall
have the meaning assigned thereto in Section 5.2(f). 
 1.25 “Residual Product” shall mean any Product,

country in the Territory, the period of time commencing on the Effective Date and ending on the date that is the latest of (i) 10 years from the date of the first Commercial Sale of such Product in such country, (ii) the expiration of the
last to expire of the Valid Claims necessary for the manufacture, use and sale of such Product in such country, or (iii) with respect only to the Licensed Technology that relates to, or is necessary or useful to practice, the Washington
Patents, the twelfth anniversary from the First Commercial Sale of Unpatented Product (as such term is defined in the Washington Agreement). 
 1.29 “Territory” shall mean the world. 
 1.30 “Third
Party” shall mean any Person who or which is neither a Party nor an Affiliate of a Party. 
 1.31 “Valid
Claim” shall mean a claim of any Patent which has not been held invalid or unenforceable by final decision of a court or other governmental agency of competent jurisdiction, unappealable or unappealed within the time allowed for appeal, and
which is not admitted to be invalid or unenforceable through reissue, disclaimer or otherwise. 
 1.32 “Washington
Patents” shall have the meaning assigned thereto in Exhibit A. 
 1.33 “Washington Product”

insurance coverage at the same levels and on the same terms and conditions as set forth in Section 11.5, which insurance shall name BMS as an additional insured, or (B) to maintain a self-insurance plan that substantially complies with the
requirements of Section 11.5, provided that BMS reasonably determines in advance in writing that such sublicensee’s or sub-sublicensee’s self-insured plan is adequate given its financial condition, and, at EMS’s request (but not
more than annually), such sublicensee or sub-sublicensee provides written evidence of such self-insurance; and (ii) to keep books and records and permit BMS to review such books and records pursuant to Sections 7.3, 7.4 and 7.5 and to observe
all other applicable terms of this Agreement. 
 (c) In the event of a breach by a sublicensee of SGI in the observance of
applicable terms of this Agreement, BMS shall be entitled to proceed, at BMS’s sole discretion, against such sublicensee and/or SGI to enforce this Agreement. In furtherance of the foregoing and BMS’s rights thereunder, each sublicense
granted by SGI pursuant to this Section 4.2 shall explicitly provide that BMS is a third party beneficiary of such sublicense.

 5.3 Third Party
Royalties. 
 (a) SGI, at its sole expense, shall pay all royalties accruing to any Third Party after the Effective Date that
result from SGI’s or its Affiliates’ or sublicensees’ activities and that SGI determines, in its reasonable business judgment, are necessary in order to exercise SGI’s rights hereunder to make, have made, use, sell or have sold
any Product (all such royalties, “Third Party Royalties”). 
 (b) SGI shall be entitled to a credit against royalties
payable to BMS under this Agreement as follows: 
 (i) If the aggregate Third Party Royalties and royalties under
Section 5.2(a) payable to BMS by SGI with respect to Net Sales of Products covered by the BR96-sFv-PE4O Program during a calendar quarter exceed an amount equal to 10% of such Net Sales, then SGI shall be entitled to a credit against royalties

(ii) If the aggregate Third Party Royalties and royalties under Section 5.2(b) payable to BMS by SGI with respect to Net Sales of
Products covered by the BR96/Drug Conjugate Program during a calendar quarter exceed an amount equal to 8% of such Net Sales, then SGI shall be entitled to a credit against royalties payable to BMS under Section 5.2(b) with respect to such Net
Sales in an amount equal to 33% of such excess, but in no event shall the royalties due under Section 5.2(b) be reduced to less than 5% of such Net Sales. 
 (iii) If the aggregate Third Party Royalties and royalties under Section 5.2(c) payable to BMS by SGI with respect to Net Sales of Products covered by the G28-5 sFv/Immunotoxin Program during a
calendar quarter exceed an amount equal to 10% of such Net Sales, then SGI shall be entitled to a credit against royalties payable to BMS under Section 5.2(c) with respect to such Net Sales in an amount equal to 33% of such excess, but in no
event shall the royalties due under Section 5.2(c) be reduced to less than 2% of such Net Sales. 
 5.4 Reduction for
Generic Competition. With respect to any country in the Territory where a Product is a Generic Product, the royalties payable to BMS under Section 5.2 with respect to Net Sales of such Product in such country shall be reduced by 50%,
commencing with the calendar quarter during which such Product first becomes a Generic Product in such country. Such reduction shall be in lieu of any other reduction with respect to such royalties under this Agreement to which SGI otherwise would
be entitled. 
 5.5 Obligation to Pay Royalties. In the event that more than one royalty rate under Section 5.2
applies with respect to the Net Sales of any Product, SGI shall pay royalties with respect to such Net Sales at the highest applicable rate. There shall be no obligation to pay 

  
 -11-

 
royalties to BMS under this Section 5 on sales of Products among SGI, its Affiliates and its sublicensees, but in such instances the obligation to pay royalties shall arise upon the sale by
SGI, its Affiliates or its sublicensees to unrelated Third Parties. 
 6. BMS IN-LICENSE EXPENSES. 

6.1 Generally. In further consideration of the right and license granted to SGI under this Agreement, SGI shall be solely
responsible for the payment of all costs, fees, milestone payments, royalties and other expenses (collectively, “BMS In-License Expenses”) that accrue and become payable by BMS under the several BMS In-Licenses, as may be amended or
renegotiated from time to time, on or after the Effective Date, and for the making of all required reports associated with any such payments. All royalties paid by SGI with respect to Net Sales of a Product that is covered by the BR96-sFv-PE4O
Program, the BR96/Drug Conjugate Program or the G28-5 sFv/Immunotoxin Program that constitute BMS In-License Expenses shall be deemed to be Third Party Royalties with respect to Net Sales of such Product for purposes of Section 5.3. SGI
acknowledges that it has received a complete and correct copy of all of the BMS In-Licenses. 
 6.2 Notices of Payment.

 (a) Within 20 days after SGI pays any BMS In-License Expense other than royalties, SGI shall provide notice of such payment to
BMS. Each such notice shall set forth the amount of such payment and the reason such payment was made. 
 (b) In conjunction
with each royalty statement provided by SGI under Section 7.1, SGI shall provide a statement of all royalties paid by SGI as BMS In-License Expense since the date of the last previous such statement provided by SGI. Each such report shall set
forth the calculation of the royalties paid by SGI as BMS In-License Expenses during the relevant period. 
 6.3 Payments
Non-Creditable. Except as expressly set forth in Section 5.3(b), SGI’s payment of BMS In-License Expenses shall not be creditable against any other payments to be paid by SGI under this Agreement. 

7. PAYMENTS AND REPORTS. 
 7.1 Payment. All royalty payments payable to BMS under this Agreement shall be paid quarterly within 60 days of the end of each calendar quarter. Each such payment shall be accompanied by a
statement, Product-by-Product and country-by-country of the amount of Net Sales during such quarter and the amount of royalties due on such Net Sales. 
 7.2 Mode of Payment. SGI shall make all payments required under this Agreement as directed by BMS from time to time in U.S. Dollars. Whenever for the purpose of calculating royalties, conversion
from any foreign currency shall be required, such conversion shall be at the rate of exchange published in The Wall Street Journal, Eastern U.S. edition, for the last business day of the calendar quarter in which such sales were made. 

  
 -12-

 7.3 Records Retention. SGI, its Affiliates and its sublicensees shall keep complete
and accurate records (specifically including originals or copies of documents supporting entries in the books of account) pertaining to the sale of Products in the Territory and covering all transactions from which Net Sales are derived for a period
of three calendar years after the year in which such sales occurred or such longer period as may be required under the respective BMS In-Licenses, and in sufficient detail to permit BMS to confirm the accuracy of royalty calculations hereunder.

 7.4 Audit Request. At the request of BMS, SGI, its Affiliates and its sublicensees shall permit an independent
certified public accountant appointed by BMS, at reasonable times and upon reasonable notice (but in no event more than once per calendar year), to examine those records and all other material documents relating to or relevant to Net Sales in the
possession or control of SGI, its Affiliates or its sublicensees, for a period of three years after such royalties have accrued, as may be necessary to: (i) determine the correctness of any report or payment made under this Agreement; or
(ii) obtain information as to the royalties payable for any calendar quarter in the case of SGI’s failure to report or pay pursuant to this Agreement. Said accountant shall not disclose to BMS any information other than information
relating to said reports, royalties, and payments. The results of any such examination shall be made available to both Parties. BMS shall bear the full cost of the performance of any such audit except as hereinafter set forth. If, as a result of any
inspection of the books and records of SGI or its Affiliates or its sublicensees, it is shown that SGI’s royalty payments under this Agreement were less than the amount which should have been paid, then SGI shall make all payments required to
be made to eliminate any discrepancy revealed by said inspection within 15 days after BMS’s demand therefor. Furthermore, if the royalty payments made by SG1 were less than 95% of the amount of royalty payments which should have been paid with
respect to the period in question, SGI shall also reimburse BMS for the cost of such examination. 
 7.5 Taxes. All
payments due under this Agreement shall be paid in full without deduction except for withholding taxes, if any, required by law in any country in the Territory with respect to such payment. In the event that SGI is required to withhold any tax to
the revenue authorities in any country in the Territory regarding any payment to BMS due to the laws of such country, such amount shall be deducted by SGI, and it shall notify BMS and promptly furnish BMS with copies of any tax certificate or other
documentation evidencing such withholding. 
 7.6 Interest on Late Payments. SGI shall pay interest on any payment to BMS
under this Agreement that is not made by the date due hereunder at a rate equal to the prime rate plus 2%, compounded monthly, obtained from The Wall Street Journal, Eastern U.S. edition, on the business day next preceding the date such
payment was due, from such date until payment in full has been made. 
 7.7 Obligations Under Ixsys Agreement.
Notwithstanding any other provision of this Agreement, with respect to Ixsys Products, SGI shall make reports to Ixsys, keep and maintain records of Net Sales and grant access to such records by an independent accountant to the same extent required
of BMS under the Ixsys Agreement.

EXPRESS OR IMPLIED WARRANTIES, INCLUDING BUT NOT LIMITED TO WARRANTIES OF QUALITY, PERFORMANCE, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT, WITH RESPECT TO THE LICENSED TECHNOLOGY, THE PRODUCTS OR ANY MATERIALS
TRANSFERRED TO SGI UNDER THIS AGREEMENT. SGI acknowledges and agrees that BMS is licensing the Licensed Technology to SGI strictly on an “AS IS, WHERE IS” basis and that SGI shall have no claims or causes of action of any kind against BMS
with respect thereto. 
 9. PATENTS; IMPROVEMENTS. 
 9.1 Patent Filing, Maintenance and Prosecution. 
 (a) Subject to
Section 9.3, with respect to Patents that are licensed to SGI exclusively under this Agreement and with respect to Improvements relating to or arising from such Patents, SGI shall have the first right, in its sole discretion and at its sole
cost and expense, to determine the strategies for prosecuting such Patents and to determine whether to maintain such Patents in each country in the Territory. With respect to Patents that are licensed to SGI partially exclusively or non-exclusively
under this Agreement and with respect to Improvements relating to or arising front such Patents, BMS shall have the first right, in its sole discretion and at its sole cost and expense, to determine the strategies for prosecuting such Patents and to
determine whether to maintain such Patents in each country in the Territory. 
 (b) In the event that the Party having the first
right to prosecute and maintain a Patent under Section 9.1(a) elects to abandon the prosecution or maintenance of any such Patents in any country in the Territory, such Party shall give the other Party notice thereof at least 60 days prior to
the date on which such other Party is required by law to make a filing in order to preserve rights to patent protection in such country, and the other Party shall have the right to do so, at its

  
 -14-

 
own expense, in the name of the owning or controlling Party. In the event that BMS elects to abandon the prosecution or maintenance in any country in the Territory of any Patent licensed to SGI
partially exclusively or non-exclusively under this Agreement and SGI elects to assume such prosecution or maintenance, then SGI shall be entitled to a credit against royalties payable to BMS pursuant to Section 5.2 with respect to Net Sales of
any Product covered by such Patent equal to the amount of the actual costs and expenses (including reasonable attorneys’ fees) incurred by SGI in connection with such prosecution or maintenance. In the event that SGI elects to abandon the
prosecution or maintenance in any country in the Territory of any Patent licensed to SGI exclusively under this Agreement and BMS elects to assume such prosecution or maintenance, then SGI’s right and license under this Agreement in such
country with respect to the Licensed Technology relating to such Patent shall terminate. 
 9.2 Information; Consultation;
Cooperation. 
 (a) With respect to the filing, prosecution and maintenance of any Patent pursuant to Section 9.1(a),
the filing Party shall keep the other Party informed of its decisions and actions in this regard by providing a report thereof to such other Party. Further, in connection with any such filing, prosecution or maintenance by either Party, such Party
shall consult with the other Party and in good faith consider and give due respect to such other Party’s position with respect thereto. In the event that the sole owning or controlling Party elects not to file for patent protection or prosecute
or maintain such Patents and the other Party elects to do so, such owning or controlling Party shall cooperate with the other Party in such filing, prosecution or maintenance. 
 (b) In addition, with respect to the filing, prosecution and maintenance of any Patent pursuant to Section 9.1(a) that covers an Improvement by a Party that does not solely own such Improvement, the
filing Party shall cooperate with the other Party in determining strategies for such filing, prosecution and maintenance, and the filing Party shall make its patent counsel available for consultation with patent counsel for the other Party for this
purpose. 
 9.3 Prior Patent Rights. Notwithstanding anything to the contrary in this Agreement, with respect to any
Patents that have been licensed to BMS under the BMS In-Licenses, the rights and obligations of the Parties under Sections 9.1 and 9.2 with respect thereto shall be subject to BMS’s licensors’ rights to participate in prosecution and
maintenance thereof, in accordance with the terms and conditions of the relevant BMS In-Licenses. 
 9.4 Improvements.

 (a) Improvements that are made by an employee or agent of SGI, solely or jointly other than with an employee or agent of BMS,
shall be owned by SGI. Improvements that are made jointly by employees or agents of SGI and BMS shall be jointly owned by SGI and BMS and treated as joint inventions under U.S. laws applicable to joint inventions. Improvements that are made by an
employee or agent of BMS, solely or jointly other than with an employee or agent of SGI, shall be owned by BMS. Except as otherwise set forth in this Agreement, each of BMS and SGI shall retain its unrestricted rights to make, have made, use, sell
and have sold all Improvements that are owned by it either solely or jointly with the other Party. 

  
 -15-

 (b) In the event that, during the term of this Agreement, either Party (the “proprietor
Party”) develops or acquires the rights to (including the right to license or sublicense) any Improvements to Licensed Technology that is licensed to SGI under this Agreement partially exclusively or non-exclusively, the proprietor Party shall
promptly disclose full and complete information relating to such Improvements to the other Party (the “non-proprietor Party”). 
 (c) With respect to any such Improvements, the proprietor Party shall grant to the non-proprietor Party a royalty-free, non-exclusive right and license, including the right to grant sublicenses thereof,
to use such Improvements during the term of this Agreement: (i) with respect to such right and license granted to SGI by BMS, solely for the manufacture, use or sale of the Products pursuant to the right and license granted to SGI under this
Agreement, and (ii) with respect to such right and license granted to BMS by SGI, (A) if such Improvement is to Licensed Technology that is licensed to SGI under this Agreement partially exclusively for cancer, for any purpose that does
not relate to human cancer; (B) if such Improvement is to Licensed Technology that is licensed to SGI under this Agreement partially exclusively for linkers, for any purpose that does not relate to monoclonal antibody targeting applications;
and (C) if such Improvement is to Licensed Technology that is licensed to SGI under this Agreement non-exclusively, for any purpose. Notwithstanding the foregoing, the non-proprietor party shall not be entitled to use any Improvement relating
to or arising from the Adept Program to develop, make, use or sell any product (including any Product) having the same primary mode of action as any product (including any Product) being developed, marketed or sold by the proprietor party.

 9.5 Prior Improvement Rights; Reporting. Notwithstanding anything to the contrary in this Agreement, SGI’s rights
in and to any Improvements relating to or arising from any Patents that have been licensed to BMS under the BMS In-Licenses shall be subject to BMS’s licensors’ rights therein under the respective BMS In-Licenses. Each Party shall be
responsible for making all reports to such licensors concerning its respective Improvements. 
 10. PATENT ENFORCEMENT: INFRINGEMENT.

 10.1 Patent Enforcement. As soon as it shall have knowledge thereof, each Party shall promptly advise the other
Party of any infringement of the Patents in the Territory by a Third Party. With respect to any Patent that is licensed to SGI exclusively under this Agreement, SGI shall have the first right, but not the duty, to institute infringement actions
against Third Parties. With respect to any Patent that is licensed to SGI partially exclusively or non-exclusively under this Agreement, BMS shall have the first right, but not the duty, to institute infringement actions against Third Parties;
provided, however, that SGI shall have the right, at its sole discretion, to participate therein at its own expense. For so long as SGI shall continue to participate materially in any such action, BMS shall consult with SGI and take into account
each Party’s relative interests in such Patent and such infringement action before entering into any settlement arrangement or other amicable arrangement with respect thereto. If the Party having the first right to institute an infringement
proceeding against an offending Third Party does not do so within 90 days after receipt of notice from the other Party, such other Party shall have the right, but not the duty, to institute such an action. The costs and expenses of any such action
(including reasonable fees of attorneys and other professionals) shall be borne by the Party instituting the action, or, if the Parties elect to cooperate in instituting and maintaining such action, such costs and expenses

  
 -16-

 
shall be borne by the Parties in such proportions as they may agree in writing. Each Party shall execute all necessary and proper documents and take such actions as shall be appropriate to allow
the other Party to institute and prosecute such infringement actions. Any award paid by Third Parties as a result of such an infringement action (whether by way of settlement or otherwise) shall be paid to the Party who instituted and maintained
such action, or, if both parties instituted and maintained such action, such award shall be allocated among the Parties in proportion to their respective contributions to the costs and expenses incurred in such action. 

10.2 Infringement Action by Third Parties. As soon as it shall have knowledge thereof, each Party shall promptly advise the other
Party of any infringement action instituted by a Third Party with respect to any Product or of any grounds for any such action, regardless of whether such action has been instituted. In the event of the institution of any suit by a Third Party
against SGI for patent infringement involving the manufacture, sale, distribution or marketing of any Product in the Territory, SGI shall have the right to defend such suit at its own expense, and BMS hereby agrees to assist and cooperate with SGI,
at its own expense, to the extent necessary in the defense of such suit; provided, however, that with respect to any suit involving Patents licensed to BMS under the BMS In-Licenses, BMS shall have the right, at its sole discretion, to participate
therein at its own expense. For so long as BMS shall continue to participate materially in any such action, SGI shall not enter into any settlement arrangement or other amicable arrangement without the prior written consent of BMS. During the
pendency of such action, SGI shall continue to make all payments due under this Agreement. If, as a result of any judgment, award, decree or settlement resulting from an action instituted by a Third Party, SGI is required to pay damages and/or a
royalty to such Third Party, SGI shall be solely responsible for the payment of such damages and/or such royalties for such Products to such Third Party and shall continue to pay royalties pursuant to this Agreement in the country which is the
subject of such action. All royalties paid by SGI pursuant to this Section 10.2 shall be deemed to constitute Third Party Royalties for purposes of Section 5.3. 
 10.3 Prior Rights. Notwithstanding anything to the contrary in this Agreement, with respect to any Patents that have been licensed to BMS under the BMS In-Licenses, the rights and obligations of
the Parties under this Section 10 with respect thereto shall be subject to BMS’s licensors’ rights to enforce and defend against infringement claims with respect to same and all other applicable provisions of the respective BMS
In-Licenses. 
 11. INDEMNIFICATION. 
 11.1 By SGI. SGI, including any successor to SGI, shall, and shall obligate its Affiliates or its sublicensees, if any, to, indemnify and hold BMS and its Affiliates, and their respective
directors, officers, employees and agents harmless from and against any and all liability, damage to or loss of property or injury to or death of any person or persons, costs and expenses (including reasonable attorney’s fees) resulting from
claims arising out of: 
 (a) negligence, recklessness or wrongful intentional acts or omissions of SGI, its Affiliates or its
sublicensees, if any, and their respective directors, officers, employees and agents, in connection with the use or development of any Licensed Technology; or 

  
 -17-

 (b) any warranty claims, Product recalls or any tort claims of personal injury (including
death) or property damage relating to or arising out of the manufacture, use, distribution or sale of any Product or services by SGI, its Affiliates or its sublicensees, if any, due to any negligence, recklessness or wrongful intentional acts or
omissions by, or strict liability of, SGI, its Affiliates or its sublicensees, if any, and their respective directors, officers, employees and agents. 
 11.2 By BMS. In the event that BMS makes, has made, uses, sells or has sold any Product pursuant to Section 13.6(c) or (d), BMS shall, and shall obligate its sublicensees, if any, to,
indemnify SGI and its Affiliates, and their respective directors, officers, employees and agents with respect thereto to the same extent as the indemnification required to be provided by SGI in Section 11.1. 

11.3 Notice. In the event that either Party is seeking indemnification under Section 11.1 or Section 11.2, such Party
shall inform the indemnifying Party of a claim as soon as reasonably practicable after it receives notice of the claim, shall permit the indemnifying Party to assume direction and control of the defense of the claim (including the sole right to
settle it at the sole discretion of the indemnifying Party, provided that such settlement does not impose any obligation on the indemnified Party), and shall cooperate as requested (at the expense of the indemnifying Party) in the defense of the
claim. 
 11.4 Complete Indemnification. As the Parties intend complete indemnification, all costs and expenses of
enforcing this Section 11 shall also be reimbursed by the indemnifying Party. 
 11.5 Insurance. 

(a) In furtherance and not in limitation of any indemnity obligations of SGI under this Agreement: (i) commencing on the Effective
Date and thereafter for the period of time required hereinbelow, SGI shall obtain and maintain on an on-going basis comprehensive general liability insurance in the amount of $1,000,000 per occurrence and $2,000,000 annual aggregate combined single
limit for bodily injury and property damage liability; and (ii) commencing not later than 30 days prior to the first use in humans of the first potential Product and thereafter for the period of time required hereinbelow, SGI shall obtain and
maintain on an on-going basis products liability insurance (including contractual liability coverage on SGI’s indemnification obligations under this Agreement) in the amount of at least $25,000,000 per occurrence and annual aggregate combined
single limit for bodily injury and property damage liability. All of such insurance coverage shall be maintained with a insurance company or companies having an A. M. Best rating of “A-” or better and an aggregate deductible not to exceed
$100,000 per occurrence. 
 (b) Not later than the Effective Date with respect to the comprehensive general liability coverage,
and not later than 30 days prior to the first use in, humans of the first potential Product with respect to the products liability coverage, SGI shall provide to BMS a certificate(s) evidencing all such required coverage hereunder. Thereafter SGI
shall maintain such insurance coverage without interruption during the term of this Agreement and for a period 

  
 -18-

 
of at least 10 years after the expiration or termination of the term and shall provide certificates evidencing such insurance coverage without interruption on an annual basis (by no later than
the annual renewal date for such coverage) during the period of time for which such coverage must be maintained. 
 (c)
SGI’s insurance shall name BMS as an additional insured, shall state that such insurance is primary to any valid and collectible insurance available to BMS that also insures the same loss for which SGI has liability pursuant to this Agreement
(including, without limitation, under the indemnification provisions hereof), shall contain a cross-liability or severability of interest clause, and shall state that BMS shall be provided at least 60 days’ prior written notice of any
cancellation or material change in the insurance policy. SGI shall promptly provide BMS with a copy of all communications passing between SGI and the carrier(s) providing the coverage required under this Section 11.5. SGI’s failure to
comply with the provisions of this Section 11.5 shall be deeded to be a material breach of this Agreement. 
 12. PUBLICATION;
CONFIDENTIALITY. 
 12.1 Notification. Both Parties recognize that the Parties may wish to publish the results of
its development efforts relating to the Products. However, both Parties also recognize the importance of acquiring patent protection on inventions. Consequently, any proposed publication by either Party on the subject matter of any of the Licensed
Technology that is licensed to SGI hereunder partially exclusively or non—exclusively, or any subject matter related thereto, shall comply with this Section 12. At least 30 days before a manuscript is to be submitted to a publisher, the
publishing Party will provide the other Party with a copy of the manuscript. If the publishing Party wishes to make an oral presentation, it will provide the other Party with a copy of the abstract (if one is submitted) at least 30 days before it is
to be submitted. The publishing Party will also provide to the other Party a copy of the text of the presentation, including all slides, posters and any other visual aids, at least 30 days before the presentation is made. 

12.2 Review of Proposed Publications. The receiving Party will review the manuscript, abstract, text or any other material
provided under Section 12.1 for the express purpose of determining whether patentable subject matter or Confidential Information (as such term is defined herein) is disclosed. The other Party will notify the publishing Party within 30 days of
receipt of the proposed publication if the other Party, in good faith, determines that patentable subject matter is or may be disclosed, or if the other Party, in good faith, believes Confidential Information or proprietary information is or may be
disclosed. If it is determined by the other Party that patent applications should be filed, the publishing Party shall delay its publication or presentation for a period not to exceed 90 days from the other Party’s receipt of the proposed
publication to allow time for the filing of patent applications covering patentable subject matter. In the event that the delay needed to complete the filing of any necessary patent application will exceed the 90-day period, the Parties will discuss
the need for obtaining an extension of the publication delay beyond the 90-day period. If it is determined in good faith by the other Party that Confidential Information or proprietary information is being disclosed, the Parties will consult in good
faith to arrive at an agreement on mutually acceptable modifications to the proposed publication to avoid such disclosure. The publishing Party of any manuscript, text or 

  
 -19-

 
oral presentation will acknowledge the other Party for its contribution to the material being published or presented. In addition, to the foregoing, SGI shall cooperate with BMS to allow BMS to
fulfill any obligations it may have under the respective BMS In-Licenses on account of any proposed publication by SGI. 
 12.3
Confidentiality; Exceptions. Except to the extent expressly authorized by or required for the performance of this Agreement or otherwise agreed in writing, the Parties agree that, for the term of this Agreement and for five years thereafter
(or any longer term provided for in any BMS In-License) the receiving Party, its Affiliates and its sublicensees (collectively, the “receiving Party”) shall keep, and shall ensure that its officers and directors keep, completely
confidential and shall not publish or otherwise disclose and shall not use for any purpose inconsistent with this Agreement any information furnished to it by the disclosing Party, its Affiliates or its sublicensees that is marked as confidential
or, if furnished orally, that the disclosing Party notifies the receiving Party is confidential within 10 days after such information is furnished, or any information developed pursuant to this Agreement (collectively, “Confidential
Information”). This Section 12.3 shall not apply to information that the receiving Party can establish: (i) is or hereafter becomes generally available to the public other than by reason of any default with respect to a
confidentiality obligation; (ii) was already known to the receiving Party when disclosed by the disclosing Party, as evidenced by prior written records; or (iii) is disclosed to the receiving Party by a Third Party who reasonably was not
known by the receiving Party to be in default of any confidentiality obligation to the disclosing Party. 
 12.4
Exceptions. 
 (a) The restrictions contained in Section 12.3 shall not apply to Confidential Information that
(i) is submitted by the receiving Party to governmental authorities to facilitate the issuance of marketing approvals for a Product, provided that reasonable measures shall be taken to assure confidential treatment of such information;
(ii) is provided by the receiving Party to Third Parties under appropriate terms and conditions, including confidentiality provisions equivalent to those in this Agreement, for consulting, manufacturing development, manufacturing, external
testing and marketing trials; or (iii) is otherwise required to be disclosed in compliance with applicable laws or regulations or order by a court or other regulatory body having competent jurisdiction; provided that if a receiving Party is
required to make any such disclosure of the other Party’s Confidential Information it will, except where impracticable for necessary disclosures, for example to physicians conducting studies or to health authorities, give reasonable advance
notice to the other Party of such disclosure requirement and, except to the extent inappropriate in the case of patent applications, will use its best efforts to secure confidential treatment of such Confidential Information required to be
disclosed. 
 (b) Nothing in Section 12.3 shall prevent SGI: (i) in connection with efforts to secure financing at any
time during the term of this Agreement, from issuing statements and sharing information as to SGI’s agreements with BMS, achievements made, and the status of the work being done, under this Agreement, so long as such statements or information
do not jeopardize the ability to obtain patent protection on Improvements or disclose technical or scientific Confidential Information; or (ii) from issuing statements that SGI determines to be necessary to comply with applicable law (including
the disclosure requirements of the U.S. 

  
 -20-

 
Securities and Exchange Commission, Nasdaq or any other stock exchange on which securities issued by SGI are traded); provided that, in the case of statements made to or information shared with
the general public, to the extent practicable under the circumstances, SGI shall provide BMS with a copy of the proposed text of such statements sufficiently in advance of the scheduled release thereof to afford BMS a reasonable opportunity to
review and comment upon the proposed text. 
 12.5 Limitations on Use. Each Party shall use, and cause each of its
Affiliates and its sublicensees to use, any Confidential Information obtained by it from the other Party, its Affiliates or its sublicensees, pursuant to this Agreement or otherwise, solely in connection with the activities or the transactions
contemplated hereby. 
 12.6 Remedies. Each Party shall be entitled, in addition to any other right or remedy it may

13.4 Breach. Failure by either Party to comply with any of the material obligations contained in this Agreement (including,
without limitation, SGI’s obligation to pay BMS In-License Expenses under Section 6) shall entitle the other Party to give to the Party in default notice specifying the nature of the default and requiring it to cure such default. If such
default is not cured within 90 days after the receipt of such notice (or, if such default cannot be cured within such 90-day period, if the Party in default does not commence and diligently continue actions to cure such default), the notifying Party

13.5 Failure to Maintain Insurance. This Agreement shall terminate automatically and without necessity of any action by either
Party in the event that (i) SGI fails to maintain all insurance coverage that it is required to maintain under Section 11.5, or (ii) a sublicensee or sub-sublicensee of SGI fails to maintain all insurance coverage that it is required
to maintain under Section 4.2(b) and SGI does not, prior to the cancellation or non-renewal of such coverage, either (A) terminate such sublicense, or (B), obtain the requisite coverage on behalf and for the benefit of such sublicense or

 1. Making,
having made, using, or selling SCA PROTEIN for Radioimmunoguided SurgeryTM (RIGS®), in which a radiolabelled SCA PROTEIN is administered to a cancer patient; time elapses for preferential concentration of the radiolabelled SCA PROTEIN in
neoplastic tissue and decrease of background radioactivity in the patient; and such preferentially concentrated radiolabelled SCA PROTEIN is detected within a surgical operative field by a detector probe placed in juxtaposition with tissue suspected
of containing said radiolabelled SCA PROTEIN. 
 2. Making, having made, using, or selling diagnostics based on erbB-2 SCA
PROTEINS and therapeutics based on erbB-2 SCA PROTEINS covalently linked to Pseudomonas exotoxin or derivatives or fragments thereof. 
 3. Making, having made, or selling reagents and kits in the research market for production and cloning of genes encoding SCA PROTEIN(s) and their fusions in a filamentous bacteriophage-derived vector
system, and for expression and screening of SCA PROTEINS fused with the minor coat protein or attachment or adsorption protein of filamentous bacteriophage. 
 4. Selling kits in the research market for cloning, screening, or isolating SCA PROTEINS. 
 5. Selling products containing SCA PROTEINS in the research market. 
 6. Selling
SCA PROTEIN-containing products to diagnostic companies for inclusion in diagnostic kits. 
 7. Making, having made, using, or
selling catalytic SCA PROTEIN in which a protein binds to and catalyzes the chemical transformation of a substrate and in which an antigen-binding site of an SCA PROTEIN is involved in said catalysis. 

8. Making, having made, using, or selling SCA PROTEINS that are, or have been modified by reaction with poly (alkylene glycols).

 9. Making, having made, using, or selling SCA PROTEINS fused with, or for the assay or purification of, Tumor Necrosis
Factor-alpha (TNF) or Lymphotoxin.
