Explanation of Responses:

( 1 )On April 23, 2019 prior to the closing of the initial public offering (the "IPO") by Pinterest, Inc. (the "Company"), the Company filed an Amended and Restated Certificate of Incorporation (the "Charter") with the Secretary of State of the State of Delaware, pursuant to which each share of common stock was automatically reclassified into one share of Class B common stock, par value $0.00001, of the Company ("Class B Common Stock"). As set forth in the Charter, each share of Class B Common Stock is convertible at any time at the option of the holder into one share of the Company's Class A common stock, par value $0.00001, of the Company ("Class A Common Stock"). Additionally, each share of Class B Common Stock will, subject to certain exceptions, convert automatically into one share of Class A Common Stock upon any transfer. ( 2 )Due to a clerical error, these shares were inadvertently omitted from the Form 4 filed on April 25, 2019. This amendment is being filed to include such shares. All other information set forth in the April 25, 2019 Form 4 remains correct. ( 3 )The reported securities are held by the LAMA Community Trust, of which Marc Andreessen and his spouse are trustees. Each of the Reporting Persons disclaims the existence of a "group" and, other than Marc Andreessen, disclaims beneficial ownership of these securities, and the inclusion of these securities in this report shall not be deemed an admission of beneficial ownership of the reported securities for purposes of Section 16 or for any other purpose.

Remarks: This report is one of two reports, each on a separate Form 4, but relating to the same transactions being reported by entities affiliated with AH Capital Management and their associated managing members.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
