This Note Purchase Agreement (this “Agreement”) is made as of June 1, 2020 by and among Chinook Therapeutics U.S., Inc., a Delaware corporation (the “Company”), and the parties listed on the Schedule of Investors attached to this Agreement as Exhibit A (each, individually, an “Investor” and collectively, the “Investors”).

A. WHEREAS, the Company currently requires funds to help finance its operations and the Investors are willing to advance funds to the Company in exchange for the issuance to them of certain convertible promissory notes evidencing the Company’s obligation to repay the Investors’ loans of the advanced funds, all as provided in this Agreement.

B. WHEREAS, concurrently with the execution and delivery hereof, Aduro Biotech, Inc., a Delaware corporation (“Parent”), Aspire Merger Sub, Inc., a Delaware corporation and a direct wholly owned subsidiary of Parent (“Merger Sub”), and the Company have entered into an Agreement and Plan of Merger and Reorganization (as such agreement may be amended or supplemented from time to time pursuant to the terms thereof, the “Merger Agreement”), which provides, among other things, for the merger of Merger Sub with and into the Company, with the Company continuing as the surviving corporation (the “Merger”), upon the terms and subject to the conditions set forth in the Merger Agreement. Capitalized terms used but not otherwise defined herein shall have the respective meanings ascribed to such terms in the Merger Agreement.

C. WHEREAS, as a condition to its willingness to enter into the Merger Agreement, Parent has required that the Company, and as an inducement and in consideration therefor, the Company has agreed to, enter into this Agreement.

NOW THEREFORE, the parties hereby agree as follows.

-2-


4.1 Authorization. This Agreement constitutes, and the other Financing Documents which constitute agreements of the Investor when executed and delivered by the Investor will constitute, such Investor’s valid and legally binding obligations, enforceable against such Investor in accordance with its terms, except as may be limited by (a) applicable bankruptcy, insolvency, reorganization or other laws of general application relating to or affecting the enforcement of creditors’ rights generally and (b) the effect of rules of law governing the availability of equitable remedies. Each Investor represents and warrants to the Company that such Investor has full power and authority to enter into this Agreement.

4.2 Purchase for Own Account. The Notes and the shares of the Company Common Stock or capital stock of Parent issuable upon the conversion of the Notes purchased by such Investor hereunder (the “Securities”) will be acquired for investment for such Investor’s own account, not as a nominee or agent, and not with a view to the public resale or distribution thereof within the meaning of the Securities Act, and such Investor has no present intention of selling, granting any participation in, or otherwise distributing the same.

4.3 No Solicitation. At no time was such Investor presented with or solicited by any publicly issued or circulated newspaper, mail, radio, television or other form of general advertising or solicitation in connection with the offer, sale and purchase of the Securities.

4.4 Disclosure of Information. Such Investor has (a) conducted its own investigation of the Company, Parent and the Securities and has not relied on any statements or other information provided by the Company or Parent concerning the Company, Parent or the Securities or the offer and sale of the Securities, (b) had access to, and an adequate opportunity to review, financial and other information as such Investor deems necessary to make its decision to purchase the Securities, (c) been offered the opportunity to ask questions of the Company and Parent and received answers thereto, as such Investor deemed necessary in connection with its decision to purchase the Securities, and (d) made its own assessment and has satisfied itself concerning the relevant tax and other economic considerations relevant to its investment in the Securities. The foregoing, however, does not in any way limit or modify the representations and warranties made by the Company in Section 3.

4.5 Excluded Information. Such Investor acknowledges that (a) the Company and Parent currently may have, and later may come into possession of, information regarding the Company, Parent and/or the Merger that is not known to such Investor and that may be material to a decision to enter into this transaction to purchase the Securities (“Excluded Information”), (b) the Investor has determined to enter into the this transaction to purchase the Securities notwithstanding our lack of knowledge of the Excluded Information, and (c) neither the Company nor Parent shall have liability to the Investor, and the Investor hereby to the extent permitted by law waives and releases any claims it may have against the Company and Parent, with respect to the nondisclosure of the Excluded Information. The foregoing, however, does not in any way limit or modify the representations and warranties made by the Company in Section 3.

4.6 No Offering Memorandum. Such Investor acknowledges that no disclosure or offering document has been prepared in connection with the offer and sale of the Securities.

4.7 No Parent Investigation. Such Investor acknowledges that Parent and its directors, officers, employees, representatives and controlling persons have made no independent investigation with respect to the Company or the Securities or the accuracy, completeness or adequacy of any information supplied to such Investor by the Company.

 

-3-


4.8 Investment Experience. Such Investor understands that the purchase of the Securities involves substantial risk. Such Investor has experience as an investor in securities of companies in the development stage and acknowledges that such Investor is able to fend for itself, can bear the economic risk of such Investor’s investment in the Securities. Such investor has such knowledge and experience in financial or business matters that such Investor is capable of evaluating the merits and risks of this investment in the Securities and protecting such Investor’s own interests in connection with this investment in the Securities.

4.9 Accredited Investor Status. Such Investor is familiar with the definition of, and qualifies as, an “accredited investor” within the meaning of Regulation D promulgated under the Securities Act.

4.10 Restricted Securities. Such Investor understands that the Securities are characterized as “restricted securities” under the Securities Act and Rule 144 promulgated thereunder (“Rule 144”) since they are being acquired from the Company or Parent in a transaction not involving a public offering, and that under the Securities Act and applicable regulations thereunder the Securities may be resold without registration under the Securities Act only in certain limited circumstances. Investor further understands that neither the Company nor Parent is under any obligation to register the Securities, and neither the Company nor Parent has any present plans to do so. Furthermore, such Investor is familiar with Rule 144, as presently in effect, and understands the limitations imposed thereby and by the Securities Act on resale of the Securities without such registration. Such Investor understands that, whether or not the Securities may be resold in the future without registration under the Securities Act, other than the Parent Common Stock, no public market now exists for any of the Securities and that it is uncertain whether a public market will ever exist for the Securities.

4.11 Further Limitations on Disposition. Without in any way limiting the representations set forth above, such Investor further agrees not to make any disposition, including without limitation pursuant to any swap, hedge, pledge or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of a Note or Conversion Stock, whether any such transaction is to be settled by delivery of Parent Common Stock or other Parent securities, in cash or otherwise, of all or any portion of the Securities unless and until:

(a) there is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such effective registration statement; or

(b) such Investor shall have notified the Company and, prior to termination of the Merger Agreement, Parent, of the proposed disposition and shall have furnished the Company and, prior to termination of the Merger Agreement, Parent, with a statement of the circumstances surrounding the proposed disposition and, at the expense of such Investor or its transferee, with an opinion of counsel reasonably satisfactory in form and substance to the Company and, prior to termination of the Merger Agreement, Parent, that such disposition will not require registration of such Securities under the Securities Act.

Notwithstanding the provisions of clauses (a) and (b) of this Section 4.8, no such registration statement or opinion of counsel shall be required for any transfer: (i) of any Securities in compliance with Rule 144 or Rule 144A promulgated under the Securities Act when the Company and, prior to termination of the Merger Agreement, Parent, is promptly provided evidence of such compliance; (ii) subject to compliance with applicable securities laws, of any Securities for no consideration by an Investor that is a partnership or a corporation to (A) a partner of such partnership or stockholders of such corporation, (B) an affiliate of such partnership or corporation, (C) a retired partner of such partnership who retires after the date hereof, (D) the estate of any deceased partner of such partnership or deceased stockholders of such corporation; or (iii) by gift, will or intestate succession by any Investor to his or her spouse or lineal descendants or ancestors or any trust for any of the foregoing; provided that in each of the foregoing cases the transferee agrees in writing to be subject to the terms of this Section 4 to the same extent as if the transferee had been an original Investor hereunder.

4.12 Legends. Such Investor understands and agrees that the certificates evidencing the Securities will bear legends substantially similar to those set forth below in addition to any other legend that may be required by applicable law, the Company’s Certificate of Incorporation or Bylaws, Section 4.8 of this Agreement, or any other agreement between the Company and such Investor:

(a) THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER THE SECURITIES LAWS OF APPLICABLE STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD, INCLUDING WITHOUT LIMITATION PURSUANT TO ANY SWAP, HEDGE, PLEDGE OR OTHER ARRANGEMENT THAT TRANSFERS TO ANOTHER, IN WHOLE OR IN PART, ANY OF THE ECONOMIC CONSEQUENCES OF OWNERSHIP OF HEREOF OR THE SECURITIES ISSUABLE UPON CONVERSION HEREOF, EXCEPT AS PERMITTED UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION UNDER SUCH LAWS OR AN EXEMPTION FROM SUCH REGISTRATION REQUIREMENT. INVESTORS SHOULD BE AWARE THAT THEY MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN INDEFINITE PERIOD OF TIME. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE WITH THE ACT AND ALL APPLICABLE STATE SECURITIES LAWS.

(b) THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO AND MAY ONLY BE TRANSFERRED IN COMPLIANCE WITH A LOCK-UP AGREEMENT, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF THE COMPANY.

2.3 Termination of Rights. Except for the right to obtain certificates representing the Conversion Stock under Section 3, all rights with respect to this Note shall terminate upon the effective conversion of the entire Balance of the Note as provided in Section 2.1 or Section 2.2, whichever is applicable. Notwithstanding the foregoing, Holder agrees to surrender this Note to the Company or Parent, as applicable (or Lost Note Documentation where applicable) as soon as practicable after conversion. In any event, Holder shall not be entitled to receive any stock certificates representing the shares of Conversion Stock issuable upon conversion of this Note unless and until Holder has surrendered the original of this Note (or Lost Note Documentation where applicable).

2.4 SEC and Exchange Requirements. Any conversion of this Note into Parent Common Stock or other securities of Parent shall be contingent upon and subject in all respects to compliance with the rules and regulations promulgated by the SEC and Nasdaq listing rules and requirements.

3. CERTIFICATES; NO FRACTIONAL SHARES. Subject to Section 2.3, as soon as practicable after conversion of this Note pursuant to Section 2.1 or Section 2.2, as applicable, the Company at its expense will cause to be issued in the name of Holder and to be delivered to Holder, a certificate or certificates for the number of shares of Conversion Stock to which Holder shall be entitled upon such conversion (bearing such legends as may be required by applicable state and federal securities laws in the opinion of legal counsel of the Company, by the Company’s Certificate of Incorporation and Bylaws and by any agreement between the Company and Holder), together with any other securities and property to which Holder is entitled upon such conversion under the terms of this Note.

4. ADJUSTMENT PROVISIONS. So long as any of the Balance of this Note remains outstanding and the conversion right under Section 2 has not terminated, the number and character of shares of Conversion Stock issuable upon conversion of this Note upon an Actual Conversion Date and, to the extent set forth in this Section 4, the Conversion Price therefor, are each subject to adjustment upon each occurrence of an adjustment event described in Sections 4.1 through 4.4 occurring between the date this Note is issued and such Actual Conversion Date:

4.1 Adjustment for Stock Splits and Stock Dividends. The Conversion Price and the number of shares of Conversion Stock shall each be proportionally adjusted as appropriate to reflect any stock dividend, stock split, reverse stock split or other similar event affecting the number of outstanding shares of Conversion Stock without the payment of consideration to Parent therefor at any time during the VWAP Period.

4.2 Adjustment for Other Dividends and Distributions. If Parent shall, after the Merger Closing and before the Actual Conversion Date, make or issue, or shall fix a record date for the determination of eligible holders of its capital stock entitled to receive, a dividend or other distribution payable with respect to the Conversion Stock that is payable in securities of the Company (other than issuances with respect to which adjustment is made under Sections 4.1 or 4.3), or in assets (other than cash dividends) (each, a “Dividend Event”), and such dividend or other distribution is actually made, then, and in each such case, Holder, upon conversion of an Actual Conversion Amount at any time after such Dividend Event, shall receive, in addition to the Conversion Stock issuable upon such conversion of the Note, the securities or other assets that would have been issuable to Holder had Holder, immediately prior to such Dividend Event, converted such Actual Conversion Amount into Conversion Stock. For the avoidance of doubt, in no event shall the contingent value rights that may be issued to Parent securityholders in connection with the Merger be considered a dividend or distribution for purposes of this Section 4.2.

4.3 Adjustment for Consolidation or Merger. If, after the Merger Closing and before the Actual Conversion Date, Parent shall consolidate with or merge into one or more other corporations or other entities, other than in connection with the Merger, and pursuant to such consolidation or merger stock, other securities or other property is issued or paid to holders of Conversion Stock (each, a “Reorganization Event”), then, and in each such case, Holder, upon conversion of an Actual Conversion Amount after the consummation of such Reorganization Event, shall be entitled to receive (in lieu of the stock or other securities and property that Holder would have been entitled to receive under the terms of this Note upon such conversion but for such Reorganization Event), the stock or other securities or property that Holder would have been entitled to receive upon the consummation of such Reorganization Event if, immediately prior to such Reorganization Event, Holder had converted such Actual Conversion Amount into Conversion Stock, all subject to further adjustment as provided in this Note, and the successor corporation or other successor entity in such Reorganization Event shall duly execute and deliver to Holder a supplement to this Note acknowledging such corporation’s or other entity’s obligations under this Note; and in each such case, the terms of the Note shall be applicable to the shares of stock or other securities or property receivable upon the conversion of this Note after the consummation of such Reorganization Event.

4.4 Reserved.

4.5 Notice of Adjustments. The Company shall promptly give written notice of each adjustment of the Conversion Price or the number or type of shares of Conversion Stock or other securities or property issuable upon conversion of this Note that is required under this Section 4.

5.2 No Voting or Other Rights. This Note does not entitle Holder to any voting rights or other rights as a stockholder of the Company or Parent, as applicable, unless and until (and only to the extent that) this Note is actually converted into shares of the Company’s capital stock or Parent’s capital stock in accordance with its terms. In the absence of conversion of this Note into Conversion Stock, no provisions of this Note and no enumeration herein of the rights or privileges of Holder, shall cause Holder to be a stockholder of the Company or Parent for any purpose. For the avoidance of doubt, this Note does not entitle Holder to any contingent value rights that may be issued to Parent securityholders in connection with the Merger, regardless of whether the Note is converted into Parent securities.
