ALTERYX, INC.

EXCHANGE AGREEMENT

August 7, 2019

[________] (the “Undersigned”), for itself and on behalf of the beneficial owners listed on Exhibit A hereto (the “Accounts”) for whom the Undersigned holds contractual and investment authority (each Account, as well as the Undersigned if it is exchanging Outstanding Notes (as defined below) referred to hereunder as, a “Holder”), enters into this Exchange Agreement (this “Agreement”) with Alteryx, Inc., a Delaware corporation (the “Company”), as of the date first written above, whereby the Holders will exchange the Exchanged Notes (as defined below) for a combination of shares of the Company’s Class A common stock, par value $0.0001 (“Exchange Shares”), and cash (“Exchange Cash” and, together with Exchange Shares, the “Exchange Consideration”), as set forth on Exhibit A hereto.

On and subject to the terms hereof, the parties hereto agree as follows:

Article I

Exchange

Section 1.1 Exchange. On and subject to the terms set forth in this Agreement, at the Closing (as defined herein), the Undersigned hereby agrees to cause each Holder to deliver to the Company the aggregate principal amount of the Company’s outstanding 0.50% Convertible Senior Notes due 2023 (such principal amount of notes, the “Outstanding Notes”) specified for such Holder on Exhibit A under the heading “Exchanged Notes” in exchange for, and the Company hereby agrees to issue to such Holder, the Exchange Consideration specified for such Holder on Exhibit A under the heading “Exchange Consideration”, plus an amount in cash equal to the accrued and unpaid interest in respect of such Holder’s Exchanged Notes (as defined herein) from, and including, the most recent date on which interest thereon was paid, to the date of Closing, as set forth on Exhibit A (“Accrued Interest”). The Outstanding Notes delivered to the Company pursuant to the terms of this Agreement in exchange for the Exchange Consideration are referred to herein as the “Exchanged Notes.” The transactions contemplated by this Agreement, including the issuance, delivery and acceptance of the Exchange Consideration and the exchange and sale of the Exchanged Notes are collectively referred to herein as the “Transactions.”

Section 1.2 Closing. Subject to the satisfaction (or waiver by the applicable parties) of the conditions set forth in Section 4.1 below, the closing of the Transactions (the “Closing”) will take place remotely via the exchange of documents and signatures on August 12, 2019 or at such time and place as the Company and the parties may agree in writing (the “Closing Date”).

At the Closing, (a) each Holder shall deliver or cause to be delivered to the Company all right, title and interest in and to its Exchanged Notes as specified on Exhibit A hereto, free and clear of any mortgage, lien, pledge, charge, security interest, encumbrance, title retention agreement, option, equity or other adverse claim thereto (collectively, “Liens”), together with any documents of conveyance or transfer that the Company may deem necessary or desirable to transfer to and confirm in the Company all right, title and interest in and to the Exchanged Notes, free and clear of any Liens (no later than 12:00 noon on the day of Closing), and (b) (i) the Company shall deliver or cause to be delivered to each Holder the Exchange Cash and the Accrued Interest specified for such

Holder on Exhibit A hereto, as specified on, and pursuant to the wire instructions provided by each Holder on, Exhibit B hereto, and (ii) the Company shall deliver to each Holder the number of Exchange Shares specified for such Holder on Exhibit A hereto, as specified on, and pursuant to the delivery instructions provided by each Holder on, Exhibit B hereto; provided, that the parties acknowledge that the delivery of the Exchange Shares may be delayed due to procedures and mechanics within the system of The Depository Trust Company (“DTC”) or the New York Stock Exchange (the “NYSE”) (including the procedures and mechanics regarding the listing of the Exchange Shares on such exchange) or other events beyond the Company’s control and that such delay will not be a default under this Agreement so long as the Company is using its reasonable best efforts to effect the issuance of the Exchange Shares.

For the avoidance of doubt, in the event of any delay in the Closing as described above, the Holders shall not be required to deliver the Exchanged Notes until the Closing occurs. The Company may at any time (whether before, simultaneously with or after the Closing) deliver Exchange Consideration to one or more other holders of Outstanding Notes or to other investors (any such issuances pursuant to agreements dated as of the date hereof, the “Aggregated Transactions”). The delivery and cancellation of the Exchanged Notes shall be effected through one-sided Deposit/Withdrawal at Custodian (DWAC) withdrawal instructions arranged by, and entered on behalf of, the Holders to DTC.
