 RECITALS 

A.    Bank and Borrower have entered into that certain Loan and Security Agreement dated as of
July 30, 2020 (as the same may from time to time be amended, modified, supplemented or restated, the “Loan Agreement”). 

B.    Bank has extended credit to Borrower for the purposes permitted in the Loan Agreement. 

C.    Borrower has requested that Bank amend the Loan Agreement to (i) add certain provisions
to allow Borrower’s parent company to be added as a co-borrower, and (ii) make certain other revisions to the Loan Agreement as more fully set forth herein. 

D.    Bank has agreed to so amend certain provisions of the Loan Agreement, but only to the extent,
in accordance with the terms, subject to the conditions and in reliance upon the representations and warranties set forth below. 

AGREEMENT 

NOW, THEREFORE, in consideration of the foregoing recitals and other good and valuable
consideration, the receipt and adequacy of which is hereby acknowledged, and intending to be legally bound, the parties hereto agree as follows: 

1.    Definitions. Capitalized terms used but not defined in this Amendment shall have the
meanings given to them in the Loan Agreement. 
 2.    Amendments to Loan Agreement. 

2.1    Section 5.12 (Viracta Royalty). A new Section 5.12 is
added to the Loan Agreement as follows: 
 5.12    Viracta Royalty. Viracta
Royalty is in complete compliance with the covenant set forth in Section 6.6(d) of this Agreement. 

2.2    Section 6.6 (Operating Accounts). A new clause (d) is
added to Section 6.6 of the Loan Agreement as follows: 
 (d)    Borrower shall
cause Viracta Royalty to transfer to Parent, within seven (7) days of receipt, all amounts received or held by Viracta Royalty other than those amounts which Viracta Royalty is contractually obligated to pay to Xoma (US) LLC and/or its


  
 1 













 
successors and assigns (“Xoma”) pursuant to that certain Royalty Purchase Agreement, dated on or about March 20, 2021, by and between Xoma and Parent. 

2.3    Section 9.8 (Borrower Liability). A new Section 9.8 is added to the Loan
Agreement as follows: 
 9.8    Borrower Liability. Any Borrower may,
acting singly, request Credit Extensions hereunder. Each Borrower hereby appoints each other as agent for the other for all purposes hereunder, including with respect to requesting Credit Extensions hereunder. Each Borrower hereunder shall be
jointly and severally obligated to repay all Obligations, including, without limitation, all Credit Extensions made hereunder, regardless of which Borrower actually receives said Credit Extension, as if each Borrower hereunder directly received all
Credit Extensions. Each Borrower waives (a) any suretyship defenses available to it under the Code or any other applicable law, including, without limitation, the benefit of California Civil Code Section 2815 permitting revocation as to
future transactions and the benefit of California Civil Code Sections 1432, 2809, 2810, 2819, 2839, 2845, 2847, 2848, 2849, 2850, 2899, and 3433, and (b) any right to require Bank to: (i) proceed against any Borrower or any other person;
(ii) proceed against or exhaust any security; or (iii) pursue any other remedy. Bank may exercise or not exercise any right or remedy it has against any Borrower or any security it holds (including the right to foreclose by judicial or non-judicial sale) without affecting any Borrower’s liability. Notwithstanding any other provision of this Agreement or other related document, each Borrower irrevocably waives all rights that it may have at
law or in equity (including, without limitation, any law subrogating Borrower to the rights of Bank under this Agreement) to seek contribution, indemnification or any other form of reimbursement from any other Borrower, or any other Person now or
hereafter primarily or secondarily liable for any of the Obligations, for any payment made by Borrower with respect to the Obligations in connection with this Agreement or otherwise and all rights that it might have to benefit from, or to
participate in, any security for the Obligations as a result of any payment made by Borrower with respect to the Obligations in connection with this Agreement or otherwise. Any agreement providing for indemnification, reimbursement or any other
arrangement prohibited under this Section 9.8 shall be null and void. If any payment is made to a Borrower in contravention of this Section 9.8, such Borrower shall hold such payment in trust for Bank and such payment shall be promptly
delivered to Bank for application to the Obligations, whether matured or unmatured. 

2.4    Section 13 (Definitions). Clause (g) of the defined term “Permitted
Investments” in Section 13.1 is amended in its entirety and replaced with the following: 

(g)    Investments (i) by Borrower in another Borrower, (ii) by Borrower in
Subsidiaries (other than Viracta Royalty and Subsidiaries that are Borrowers hereunder) not to exceed Fifty Thousand Dollars ($50,000) in the aggregate in any twelve (12) month period, and (iii) by Subsidiaries (other than Subsidiaries
that are Borrowers hereunder) in other Subsidiaries (other than Viracta Royalty) or in Borrower;

Section 13.1 are amended in their entirety and replaced with the following:

owner” (as defined in Rules 13(d)-3 and 13(d)-5 under the Exchange Act), directly or indirectly, of fifty percent (50%) or more of the ordinary voting power for the
election of directors of Parent (determined on a fully diluted basis) other than by the sale of Parent’s equity securities in a public offering or to venture capital or private equity investors so long as Borrower identifies to Bank the venture
capital or private equity investors at least seven (7) Business Days prior to the closing of the transaction and provides to Bank a description of the material terms of the transaction; (b) during any period of 12 consecutive
months, a majority of the members of the board of directors or other equivalent governing body of Borrower cease to be composed of individuals (i) who were members of that board or equivalent governing body on the first day of such period,
(ii) whose election or nomination to that board or equivalent governing body was approved by individuals referred to in clause (i) above constituting at the time of such election or nomination at least a majority of that board or
equivalent governing body or (iii) whose election or nomination to that board or other equivalent governing body was approved by individuals referred to in clauses (i) and (ii) above constituting at the time of such election or
nomination at least a majority of that board or equivalent governing body; or (c) except as permitted by Section 7.3, at any time, Borrower shall cease to own and control, of record and beneficially, directly or indirectly, one hundred
percent (100%) of each class of outstanding capital stock of each Subsidiary (other than directors’ qualifying shares or other similar shares as required by applicable law) of Borrower free and clear of all Liens (except Liens created by this

 EXHIBIT A 

The Collateral consists of all of Borrower’s right, title and interest in and to the following personal property: 

All goods, Accounts (including health-care receivables), Equipment, Inventory, contract rights or rights to payment of money,
leases, license agreements, franchise agreements, General Intangibles, commercial tort claims, documents, instruments (including any promissory notes), chattel paper (whether tangible or electronic), cash, deposit accounts, fixtures, letters of
credit rights (whether or not the letter of credit is evidenced by a writing), securities, and all other investment property, supporting obligations, and financial assets, whether now owned or hereafter acquired, wherever located; and 

all Borrower’s Books relating to the foregoing, and any and all claims, rights and interests in any of the above and all
substitutions for, additions, attachments, accessories, accessions and improvements to and replacements, products, proceeds and insurance proceeds of any or all of the foregoing. 

Notwithstanding the foregoing, the Collateral does not include (a) any interest of Borrower as a lessee or sublessee
under a real property lease; (b) rights held under a license that are not assignable by their terms without the consent of the licensor thereof (but only to the extent such restriction on assignment is enforceable under applicable law); (c) any
interest of Borrower as a lessee under an Equipment lease if Borrower is prohibited by the terms of such lease from granting a security interest in such lease or under which such an assignment or Lien would cause a default to occur under such lease;
provided, however, that upon termination of such prohibition, such interest shall immediately become Collateral without any action by Borrower or Bank; (d) more than sixty-five percent (65%) of the presently existing and hereafter arising
issued and outstanding shares of capital stock owned by Borrower of any Foreign Subsidiary which shares entitle the holder thereof to vote for directors or any other matter, but only to the extent that pledging greater than sixty-five percent (65%)
of such stock of such Foreign Subsidiary would result in a material net increase in tax liability for Borrower and such Foreign Subsidiary taken as a whole (taking into account (i) any applicable offsets related to credits for the underlying
foreign income taxes in the case of additional US income taxes required to be paid as a result of a deemed dividend and (ii) the application of net operating loss carry forwards, if any); or (e) any Intellectual Property; provided,
however, the Collateral shall include all Accounts and all proceeds of Intellectual Property. If a judicial authority (including a U.S. Bankruptcy Court) would hold that a security interest in the underlying Intellectual Property is necessary to
have a security interest in such Accounts and such property that are proceeds of Intellectual Property, then the Collateral shall automatically, and effective as of the Effective Date, include the Intellectual Property to the extent necessary to
permit perfection of Bank’s security interest in such Accounts and such other property of Borrower that are proceeds of the Intellectual Property. 

Notwithstanding the foregoing, the Collateral shall exclude (i) the assets commonly known as “TAK-580/DAY101” and “vosaroxin” (the “Monetized Assets”), and (ii) automatically and as of such consummation, upon the consummation of a sale, license or other monetization (the
“Asset Sale”) of the assets commonly known as “Vecabrutinib” and “SNS-510” (the “Sold Assets”), the Sold Assets; provided, however, that the Collateral shall include any
consideration or other proceeds of the Monetized Assets and the Sold Assets received by Borrower, whether under a sale of the Monetized Assets or the Asset Sale or otherwise, whether now owned or hereafter acquired. 












 Pursuant to the terms of a certain negative pledge arrangement with Bank,
Borrower has agreed not to encumber any of its Intellectual Property without Bank’s prior written consent.
