Ladies and Gentlemen:

We have examined the Registration Statement on Form S-8 (the “Registration Statement”) to be filed by BlackLine, Inc., a Delaware corporation (the “Company”), with the Securities and Exchange Commission on or about the date hereof, in connection with the registration under the Securities Act of 1933, as amended, of 2,734,132 shares of the Company’s common stock, par value $0.01 per share (the “Shares”), reserved for issuance pursuant to the BlackLine, Inc. 2016 Equity Incentive Plan (the “Plan”).
