AMENDMENT TO 
 AMENDED AND RESTATED

 INVESTORS’ RIGHTS AGREEMENT 
 OF SEATTLE GENETICS, INC. 
  
 This Amendment (the “Amendment”) to the Amended and Restated Investors’ Rights Agreement dated as of December 22, 1999, as amended to date (the “Existing Rights Agreement”), is entered into as of July
8, 2003 by and among Seattle Genetics, Inc., a Delaware corporation (the “Company”), and the undersigned Investors and Founders holding at least a majority of the Registrable Securities under the Existing Rights Agreement.
Capitalized terms used herein without definition shall have the meanings assigned to them in the Existing Rights Agreement. 
  
 RECITALS 
  
 A. The Company and the undersigned Investors and Founders are parties to the Existing Rights Agreement. 
  
 B. The Existing Rights Agreement may be amended with the written consent of
the Company and the holders of a majority of the Registrable Securities thereunder. The undersigned Investors and Founders hold at least the requisite number of Registrable Securities to amend the Existing Rights Agreement pursuant to the terms
thereof. 
  
 C. The Company and the undersigned Investors and
Founders have agreed to amend the Existing Rights Agreement as set forth herein. 
  
 NOW, THEREFORE, in consideration of the foregoing recitals and the mutual promises hereinafter set forth, the parties hereto agree as follows: 
  
 1. Amendment of Underwriting Requirements Section. Section 1.8 of the Existing Rights Agreement is hereby
amended to read in its entirety as follows: 
  
 “1.8 Underwriting Requirements. In connection with any offering involving an underwriting of shares of the Company’s capital stock, the Company shall not be required under Section 1.3 to include any of the Holders’
securities in such underwriting unless they accept the terms of the underwriting as agreed upon between the Company and the underwriters selected by it (or by other persons entitled to select the underwriters), and then only in such quantity as the
underwriters determine in their sole discretion will not jeopardize the success of the offering by the Company. If the total amount of securities, including Registrable Securities, requested by stockholders to be included in such offering exceeds
the amount of securities sold other than by the Company that the underwriters determine in their sole discretion is compatible with the success of the offering, then the Company shall be 

 
required to include in the offering only that number of such securities, including Registrable Securities, which the underwriters determine in their sole
discretion will not jeopardize the success of the offering (the securities so included to be apportioned pro rata among the selling stockholders according to the total amount of securities entitled to be included therein owned by each selling
stockholder or in such other proportions as shall mutually be agreed to by such selling stockholders) but in no event shall (i) the aggregate amount of securities of the selling Holders and the holders of Registrable Shares (as defined in the
Investor Rights Agreement dated as of the closing of the Company’s Series A convertible preferred stock financing (the “New Rights Agreement”)) included in the offering be reduced below fifty percent (50%) of the total amount
of securities included in such offering, (ii) any securities held by a Founder be included if any securities held by any selling Holder are excluded or (iii) shares of any other selling shareholder, other than a holder of Registrable Shares, be
included in such registration which would reduce the number of shares which may be included by Holders, without the prior written consent of Holders of not less than 66-2/3% of the Registrable Securities proposed to be sold in the offering. For
purposes of the preceding parenthetical concerning apportionment, for any selling stockholder which is a holder of Registrable Securities and which is a partnership or corporation, the partners, retired partners and stockholders of such holder, or
the estates and family members of any such partners and retired partners and any trusts for the benefit of any of the foregoing persons shall be deemed to be a single “selling stockholder,” and any pro-rata reduction with respect to
such “selling stockholder” shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such “selling stockholder,” as defined in this sentence. For purposes of
determining the apportionment of shares to be registered pursuant to Section 1.3 of this Agreement, such apportionment shall be made in accordance with Section 4.2 of the New Rights Agreement.” 
  
 2. Conflicts with New Rights Agreement. In the event
that any term or provision of the Existing Rights Agreement, as amended by this Amendment, shall conflict in any manner with a term or provision of the New Rights Agreement, such term or provision of the New Rights Agreement shall control.

  
 3. Acknowledgement Regarding Inapplicable
Provisions. The parties hereto acknowledge that the following provisions of the Existing Rights Agreement are no longer applicable due to the completion by the Company of a Qualified IPO on March 9, 2001: Section 2.1 (Delivery of Financial
Statements), Section 2.2 (Inspection), Section 2.3 (Right of First Offer) and Section 2.4 (Board Observation Right). 
  
 4. No Other Amendments. Except as expressly amended as set forth above or as it conflicts with the New Rights Agreement as described in
Section 2 above, the Existing Rights Agreement shall remain in full force and effect in accordance with its terms. 

 5. Counterparts. This Amendment may be executed by facsimile and may be executed in
counterparts, each of which shall be deemed an original and all of which together shall constitute one document. 
  
 [Signature Page Follows] 
  

 IN WITNESS WHEREOF, the parties have executed this Amendment as of the date first written above.

 Exhibit 10.1 
  
 FIRST AMENDMENT TO LEASE 
  
 This First Amendment to Lease (this “First Amendment”) is made this 28th day of May, 2003, by and between B&N 141-302, LLC
(“Landlord”) and Seattle Genetics, Inc. (“Tenant”). 
  
 RECITAL 
  
 This Landlord and Tenant are parties
to that certain Lease dated December 1, 2000 (the “Lease”), for premises located at 21823 30th Drive SE, Bothell, Washington 98021 (the “Premises”). 
  
 Concurrent with the Lease, Tenant entered into a Pledge Agreement, an Account Control Agreement, and an Account Management
Agreement (collectively the “Pledge Documents”) for a pledge of securities and other collateral to be held in an account (the “Pledge Account”) in satisfaction of security deposit requirements of the Lease. 
  
 Pursuant to the Lease, Tenant was further entitled to a Tenant Improvement
Allowance as set forth in paragraph D of Exhibit C of the Lease. 
  
 Landlord and Tenant wish to modify the provisions of Section 4 of the Lease providing for reduction of the amount held in the Pledge Account, and modifying the time period within which Tenant may draw the Tenant Improvement Allowance, all
as more fully set forth herein. 
  
 Any capitalized terms not
otherwise defined in this First Amendment shall have the meanings assigned in the Lease. 
  
 AGREEMENT 
  
 Now,
therefore, for good and valuable consideration, the parties hereto agree as follows: 
  
 1. There is hereby added a new section 4.4 as follows: 
  
 4.4 Modifications to Section 4.3. 
  
 a. In 2001, Tenant achieved a capitalized value in excess of $[***] which, pursuant to Section 4.3, reduced the required Security Deposit and Pledge Account to $[***] (a “Capitalized Value Reduction”).
Subsequent reductions in Tenant’s capitalized value would, under the terms of the Lease, require reversal of the Capitalized Value Reduction. Landlord confirms, however, that it has waived the requirement of such reversal for the period up to
the date hereof. Landlord’s waiver has relied, among other factors, on Tenant’s representation and warranty that it was not aware of any defaults by either Landlord or Tenant under the Lease or Pledge Documents nor any event or condition
that if left uncured would constitute a default with the passage of time, which representation and warranty Tenant hereby confirms as of the date of this First Amendment. 
  

 1 

 [***] Confidential treatment requested 
  
 b. From and after the date hereof, the following provisions shall govern the required amount of the Security Deposit and
Pledge Account: The Security Deposit and Pledge Account may remain at $[***], provided that if the capitalized value of Tenant reduces below $[***], or if the cash and cash equivalents, including short and long term investments in marketable
securities, restricted investments, and interest receivables associated with investments in marketable securities, held by Tenant free and clear of all liens and pledges except the Pledge Account falls below $[***], or if Tenant’s total
stockholder equity established pursuant to GAAP falls below $[***], then the Capitalized Value Reduction shall be reversed and the amount of the Security Deposit and Pledge Account shall be restored to the full amount required but for the
Capitalized Value Reduction. Thereafter, the Capitalized Value Reduction shall be reinstituted if Tenant’s capitalized value reaches a value of $[***], and shall be reversed again if the capitalized value thereafter reduces below $[***] or if
Tenant’s unpledged cash and equivalents (plus amounts held in the Pledge Account) fall below $[***], or if Tenant’s total stockholder equity falls below $[***], and so on from that point with capitalized value trigger points of $[***] and
$[***] respectively, a cash and equivalents trigger point of $[***], and a total stockholder equity trigger point of $[***]. However, in no event shall the Security Deposit and Pledge Account in any circumstances fall below $[***] as provided for
under Section 4.3 of the lease. 
  

	 	2.	 	Additional Security. 

  
 a. As additional security for Tenant’s performance of its obligations under the Lease, Tenant agrees to provide Landlord with a first lien security
interest in all of its furniture, fixtures and equipment excepting only leased photocopiers (the “Pledged Personalty”) as set forth in the Security Agreement and UCC-1 filing attached hereto as Exhibit A. In the event the Pledge Account is
increased to [***] ($[***]), Landlord agrees to release its security interest in the Pledged Personalty, provided that if a Capitalized Value Reduction thereafter occurs, Tenant agrees to execute a new security interest in the Pledged Personalty,
and no such Capitalized Value Reduction shall be effective unless Tenant is able at such time to grant Landlord a first lien security interest in the Pledged Personalty. Landlord shall be entitled to realize on the Pledged Personalty to cure any
monetary defaults of Tenant under the Lease (whether defaults in periodic payments, reimbursements or indemnifications), and may seek such recovery against the Security Deposit and/or the Pledged Personalty in such order as Landlord may see fit in
accordance with the terms of the Lease and the Security Agreement. 
  
 b. Concurrent with filing the UCC-1, Tenant shall provide Landlord with a UCC-1 insurance policy satisfactory to Landlord. Tenant shall be responsible for the costs of the first UCC-1 insurance policy. In the event Landlord elects to
require future UCC-1 insurance policies following any subsequent Capitalized Value Reductions, the cost of the subsequent UCC-1 insurance policies shall be shared equally between Landlord and Tenant. 
  
 3. Tenant Improvement Allowance. Landlord and Tenant agree that there
remains [***] ($[***]) in unexpended Tenant Improvement Allowance pursuant to Exhibit C of the Lease. Landlord hereby agrees that Tenant may draw the remaining Tenant Improvement Allowance pursuant to the terms of Exhibit C of the Lease at any time
prior to [***], provided 
  

 2 

 [***] Confidential treatment requested 
  
 that Tenant shall not be entitled to draw any portion of the remaining Tenant Improvement Allowance unless Tenant is in full compliance with
the requirements of Section 4 of the Lease (as the same may be modified from time to time). 
  
 4. Except as specifically set forth herein, the Lease is and remains in full force and effect.

 In consideration of extensions of credit or other financial
accommodations, now existing or hereafter made, Debtor represents and warrants to, and agrees with Secured Party, as follows: 
  
 1. Definitions. As used in this Agreement: 
  
 “Collateral” means all of the Furniture, Fixtures and Equipment of Debtor set forth in Exhibit A, located at 21823 30th Drive SE,
Bothell, WA and now owned or hereafter acquired by Debtor, including Proceeds and Products of the foregoing, excepting any leased photocopiers. 
  
 “Default” means any event referred to in section 4 of this Agreement. 
  
 “Obligations” means any monetary obligations of
Debtor (whether scheduled or unscheduled payments, deposits, required reimbursements or indemnifications) under that certain Lease between Debtor and Secured Party dated December 1, 2000, as amended by First Amendment dated May 28, 2003 (the
“Lease Amendment”), for premises located at 21823 30th Drive SE, Bothell, WA to the extent such monetary obligations are not paid as and when due. 
  
 “UCC” means the Uniform Commercial Code (“UCC”). Any capitalized term used but not defined in this Security Agreement
shall have the meaning given to the term in the UCC. 
  
 2.
Security Interest. Debtor hereby grants to Secured Party a security interest in all of Debtor’s right, title and interest in and to the Collateral, to secure the prompt and unconditional payment and performance of the Obligations.

  
 3. Debtor’s Covenants. 

 
 a. Liens. Debtor shall, at its own expense keep the
Collateral free of all liens and encumbrances except (i) the security interest of Secured Party, (ii) liens arising in connection with taxes or other governmental charges or assessments which are not yet due and payable or are being contested in
good faith, provided that adequate reserves for the payment thereof have been established in accordance with generally accepted accounting principles, (iii) liens of

 [***] Confidential treatment requested 
  
 carriers, warehousemen and vendors and other similar liens imposed by law incurred in the ordinary course of business for sums not overdue
more than 45 days or being contested in good faith, provided that adequate reserves for the payment thereof have been established in accordance with generally accepted accounting principles, (iv) purchase money liens that will be discharged upon
Debtor’s payment of the purchase price for the applicable property, to the extent such liens relate solely to the property so purchased and (v) other liens, provided that the aggregate amount of indebtedness secured by such other liens does not
exceed $[***] at any time. 
  
 b. Location, Removal, Sale or
Disposition. All Collateral is located solely within the State of Washington at 21823 30th Drive SE, Bothell, Washington, 98021 (the “Premises”). Without the prior written consent of Secured Party, Debtor will not remove the
Collateral from the Premises, nor sell or dispose of the Collateral, nor hold the Collateral for sale or lease to third parties, other than removals, sales or other dispositions (i) of obsolete or worn-out Collateral or (ii) in the ordinary course
of business. 
  
 c. Insurance. Debtor will keep the
Collateral continuously insured against fire, theft, malicious mischief, and such additional hazards as are presently included in Special Form (also known as “all-risk”) insurance coverage. The policy will value the property using
replacement cost. The lender’s loss-payable endorsement will be added to the policy naming Secured Party. Upon execution of this Agreement and periodically upon renewal of the policy or policies, Debtor will deliver a certificate of insurance
providing evidence of coverage to Secured Party. In the event of loss, Secured Party shall have full power to collect any and all proceeds of insurance upon the Collateral and to apply the same at its option to any obligation secured hereby, whether
or not matured, or to the restoration or repair of the Collateral. Secured Party shall have no liability whatsoever for any loss that may occur by reason of the omission or lack of coverage of any such insurance. Debtor shall not enter into any
final settlement of any claim under any insurance policy on the Collateral without the prior written consent of Secured Party. 
  
 d. Expenditures by Secured Party. Debtor will reimburse Secured Party upon demand for any expenditures by Secured Party for the maintenance,
protection and preservation of the Collateral or Secured Party’s security interest in the Collateral, including taxes, levies, insurance and repairs, and for the collection, repossession, holding, preparation and sale or other disposition of or
realization upon the Collateral. In no event shall Secured Party have any obligation to make such expenditures nor any liability for failing to make them. 
  
 e. Governmental Charges. Debtor shall pay before delinquency all taxes, assessments and other governmental charges which are or may become a
lien on any of the Collateral, except that no charge need be paid if (i) the validity of such charge is being contested in good faith by appropriate proceedings, (ii) such proceedings do not involve any material danger of the sale, forfeiture or
loss of the Collateral or any interest in the Collateral and (iii) adequate reserves for the payment thereof have been established in accordance with generally accepted accounting principles. 
  

 2 

 [***] Confidential treatment requested 
  
 f. Access and Review. Secured Party shall at all times, upon reasonable advance notice, have the right to
inspect any of Debtor’s records relating to the Collateral and the right to obtain copies of those records. Secured Party shall at all times, upon reasonable advance notice, have the right to visit Debtor’s premises during regular business
hours to inspect the Collateral. 
  
 4. Defaults.
Each of the following shall be a default (“Default”) under this Agreement: 
  
 a. Any material default or event of default, after notice and opportunity to cure in accordance with the terms of the Lease and the Lease Amendment, on any of the Obligations, whether or not the Obligations
have been accelerated; or 
  
 b. Any failure fully and
timely to comply with any provision of this Agreement, if such failure shall continue for five (5) business days after notice of such failure; 
  
 c. Any transfer, disposition, levy, attachment or execution on, or seizure of, any of the Collateral; or 
  
 d. Dissolution, termination of existence, insolvency or bankruptcy of
Debtor or appointment of a receiver to take possession of any of the Collateral. 
  
 5. Rights and Remedies of Secured Party. 
  
 a. General. In addition to the rights and remedies granted to Secured Party in this Agreement, Secured Party shall at all times have the rights and remedies of a secured party under the Uniform
Commercial Code as enacted in the state of Washington and under all other applicable laws. 
  
 b. Remedies. After the occurrence, and during the continuance, of a Default, Secured Party may take any one or more of the following actions in its sole discretion: 
  
 (i) Pay or perform any obligation of Debtor, which Debtor is
required by this Agreement to pay or perform and add the amount so paid to the Obligations secured hereby. 
  
 (ii) Enter the premises of Debtor and take custody of, sell or remove the Collateral, without notice or demand and without judicial process,
liability for trespass or the responsibility to post a bond or other financial undertaking. 
  
 (iii) Require the Debtor to assemble the Collateral, and make it available to Secured Party at Debtor’s premises or at any other location selected by Secured Party, where it 
  

 3 

 [***] Confidential treatment requested 
  
 will remain at Debtor’s expense pending sale or other disposition. Debtor acknowledges and agrees that any failure by it to assemble
the Collateral and make it available to Secured Party will constitute a threat of imminent and irreparable harm to Secured Party which will entitle Secured Party to seek a court order or injunction: (A) appointing a receiver to take possession of
the Collateral and sell or otherwise realize upon the Collateral and apply the proceeds to the Obligations; and/or (B) directing Debtor to assemble the Collateral and make it available to Secured Party as required by this Security Agreement. Debtor
agrees that Secured Party shall be entitled to such relief upon and after a Default regardless of whether Debtor is solvent or insolvent, and regardless of whether Secured Party is oversecured or undersecured, and regardless of any other fact or
event other than the existence of a Default. Debtor expressly waives any right to require either Secured Party or the receiver to post a bond or other security or financial undertaking as a condition to obtaining any such order or injunction. All
fees of the receiver shall become a part of the Obligations payable upon demand by Secured Party. 
  
 (iv) Sell, lease or otherwise dispose of the Collateral and apply the proceeds thereof to the Obligations. If notice of sale or disposition of
Collateral is required, ten (10) calendar days notice of any intended sale or other disposition of the Collateral shall be deemed to be reasonable. 
  
 (v) Secured Party may comply with any applicable State or federal law requirements in connection with a disposition of the Collateral and
compliance will not be considered adversely to affect the commercial reasonableness of any sale of the Collateral. 
  
 c. Deficiency. Debtor shall pay any deficiency remaining after application of the net proceeds of the Collateral to the Obligations.

  
 6. Waiver of Defenses. Debtor agrees that
Secured Party may enforce this Agreement without the necessity of resorting to or exhausting any security or collateral and without the necessity of enforcing any guarantees. Debtor hereby waives the right to require Secured Party to proceed against
any other person or entity, including, without limitation, any other guarantor named herein, to foreclose any lien on any real or personal property, or to exercise any right or remedy with respect to the Obligations. 
  
 7. Effectiveness. This Agreement shall remain in full
force and effect until (i) all of the Obligations shall have been indefeasibly paid in full in cash, and (ii) this Agreement shall have been terminated in writing by Secured Party. 
  
 8. Legal Expenses. In the event of any Default under this Agreement, any of the Obligations or any
guaranty of any of the Obligations, or in the event that any dispute arises relating to the interpretation, enforcement or performance of any of the foregoing, Secured Party shall be entitled to collect from Debtor on demand all fees and expenses
incurred in connection therewith, including but not limited to fees of attorneys. Without limiting the generality of the foregoing, Debtor shall pay all such costs and expenses incurred in connection with: (a) trial court actions and appeals; (b)
bankruptcy or other insolvency proceedings of Debtor, any guarantor or other party liable for any of the Obligations or any party having any interest in any 
  

 4 

 [***] Confidential treatment requested 
  
 security for any of the Obligations; (c) judicial or nonjudicial foreclosure on any security for any of the Obligations; (d) post-judgment
collection proceedings; (e) all claims, counterclaims, cross-claims and defenses asserted in any of the foregoing whether or not they arise out of or are related to this Agreement; (f) all preparation for any of the foregoing; and (g) all settlement
negotiations with respect to any of the foregoing. 
  
 9. Interest on Expenditures. All expenditures, fees, costs and other amounts for which Debtor is required to reimburse Secured Party under this Agreement shall be payable upon demand and shall bear interest at the rate
of twelve percent (12%) per year or the highest rate permitted by law whichever is lower. 
  
 10. Perfection. Debtor shall take all actions and execute all documents reasonably required by Secured Party in order to perfect the security interests granted in this Agreement. Debtor hereby
authorizes and appoints Secured Party as its attorney-in-fact to execute such financing statements describing the Collateral and other documents as may be necessary or appropriate in Secured Party’s reasonable judgment to perfect such security
interests. Such power is coupled with an interest and shall be irrevocable until all the Obligations shall have been indefeasibly paid and performed in full. 
  
 11. Governing Law. This Security Agreement shall be governed by, and construed in accordance with the
laws of the state of Washington. 
  
 12. Binding
Effect. This Security Agreement shall bind and shall inure to the benefit of the heirs, legatees, executors, administrators, successors and assigns of Secured Party and shall bind all persons who become bound as a debtor to this Security
Agreement. 
  
 13. Entire Agreement; Amendment.
This Agreement and the other written documents, instruments and agreements entered into in connection with this Agreement and the Obligations contain the complete and final expression of the entire agreement of the parties. No provision of this
Agreement may be amended, modified, waived or supplemented, except by a writing signed by the parties sought to be charged with the amendment, modification, waiver or supplementation. No waiver by Secured Party of any Default shall be a waiver of
any other Default.
