CUSIP No.  625207105 13D Page 22 of 34 Pages

On March 20, 2018, the Issuer entered into an Agreement and Plan of Merger (the "Merger Agreement") with salesforce.com, inc.

("Lightspeed Select"), Lightspeed Venture Partners VII, L.P. ("Lightspeed VII") (the "Tender Agreement"), and separate Tender and Support Agreement with Simon Parmett, Gregory Schott, Robert Horton, Matthew Langdon, Ross Mason, Ann Winblad, Little Family 1995 TR, Ravi Mhatre and Mhatre Investments LP-Fund 4 (collectively, with the Tender Agreement, the "Tender Agreements") (each, a "Stockholder" and collectively, the "Stockholders") pursuant to which each Stockholder agreed, among other things, and subject to the terms and conditions of the Tender Agreements, to vote the shares of Common Stock, Class B Common Stock, Company RSUs or Company Options, as applicable, that each Stockholder owns (i) against any action or agreement that would be reasonably expected to (A) result in a breach of any covenant, representation or warranty or any other obligation or agreement of the Issuer contained in the Merger Agreement, or any Stockholder contained in the Tender Agreements, or (B) result in certain conditions set forth in the Merger Agreement to not be satisfied; (ii) against any change in the Issuer's Board of Directors that is not recommended by the Issuer's Board of Directors; and (iii) against other proposals for acquisition as specified in the Merger Agreement. The Tender Agreements terminate upon certain events, including the termination of the Merger Agreement in accordance with its terms.

As a result of the Tender Agreement, the Reporting Persons may be deemed to be members of a "group" with the parties to the Tender Agreements, including Salesforce, Lightspeed Select, Lightspeed VII, Simon Parmett, Gregory Schott, Robert Horton, Matthew Langdon, Ross Mason, Ann Winblad, Little Family 1995 TR, Ravi Mhatre and Mhatre Investments LP-Fund 4.  As of March 20, 2018, based on the Tender Agreements, (i) Lightspeed Select and certain of its affiliates own 3,171,808 shares of Class B Common Stock, (ii) Lightspeed VII and certain of its affiliates own 10,847,715 shares of Class B Common Stock, and (iii) Simon Parmett, Gregory Schott, Robert Horton, Matthew Langdon, Ross Mason, Ann Winblad, Little Family 1995 TR, Ravi Mhatre and Mhatre Investments LP-Fund 4 and certain of their affiliates own the Common Stock, Class B Common Stock, Company RSUs or Company Options, as applicable, listed on Schedule A of Exhibit 10.2 to the Issuer's Form 8-K filed with the SEC on March 21, 2018 (the "8-K").¹

CUSIP No.  625207105 13D Page 23 of 34 Pages

Item 5. Interest in Securities of the Issuer.

NEA 14, NEA 15 and NEA 15-OF are the record owners of Class B common stock ("Class B Common Stock") as described below. As described in the Issuer's Form 10-K filed with the Securities and Exchange Commission on February 22, 2018 (the "10-K"), holders of Class B Common Stock are entitled to ten votes per share while holders of the Common Stock are entitled to one vote per share.   In addition, holders of Class B Common Stock and holders of Common Stock generally vote together as a single class. This single class would consist of 131,500,940 shares, which includes (i) 88,896,679 shares of Common Stock (the "10-K Shares") and (ii) 42,604,261 shares of Class B Common Stock reported by the Issuer to be outstanding as of December 31, 2017 on the 10-K.  As further described in the 10-K, each share of Class B Common Stock is convertible by the holder at any time into one share of Common Stock and each such share will convert automatically into Common Stock upon the occurrence of certain other events.

NEA 14 is the record owner of 12,679,970 shares of Class B Common Stock as of March 20, 2018 (the "NEA 14 Class B Shares"). As each NEA 14 Class B Share is convertible by the holder at any time into one share of Common Stock, as described above, NEA 14 may therefore be deemed to own beneficially 12,679,970 shares of Common Stock (the "NEA 14 Common Shares"). As the sole general partner of NEA 14, NEA Partners 14 may be deemed to own beneficially the Shares.  As the sole general partner of NEA Partners 14, NEA 14 GP likewise may be deemed to own beneficially the NEA 14 Common Shares.  As the individual directors of NEA 14 GP, each of the Dual Managers, Barrett and Kerins also may be deemed to own beneficially the NEA 14 Common Shares.

NEA 15 is the record owner of 2,576,939 shares of Class B Common Stock as of March 20, 2018 (the "NEA 15 Class B Shares"). As each NEA 15 Class B Share is convertible by the holder at any time into one share of Common Stock, as described above, NEA 15 may therefore be deemed to own beneficially 2,576,939 shares of Common Stock (the "NEA 15 Common Shares"). As the sole general partner of NEA 15, NEA Partners 15 may be deemed to own beneficially the NEA 15 Common Shares.  As the sole general partner of NEA Partners 15, NEA 15 GP likewise may be deemed to own beneficially the NEA 15 Common Shares.  As the individual managers of NEA 15 GP, each of the Dual Managers, Makower and Sakoda also may be deemed to own beneficially the NEA 15 Common Shares.

NEA 15-OF is the record owner of 858,978 shares of Class B Common Stock as of March 20, 2018 (the "NEA 15-OF Class B Shares"). As each NEA 15-OF Class B Share is convertible by the holder at any time into one share of Common Stock, as described above, NEA 15-OF may therefore be deemed to own beneficially 858,978 shares of Common Stock (the "NEA 15-OF Common Shares" and, collectively with the NEA 14 Common Shares and the NEA 15 Common Shares, the "Firm Shares"). As the sole general partner of NEA 15-OF, NEA Partners 15-OF may be deemed to own beneficially the NEA 15-OF Common Shares.  As the sole general partner of NEA Partners 15-OF, NEA 15 GP likewise may be deemed to own beneficially the NEA 15-OF Common Shares.  As the individual managers of NEA 15 GP, each of the Dual Managers, Makower and Sakoda also may be deemed to own beneficially the NEA 15-OF Common Shares.

By virtue of their relationship as affiliated entities, whose controlling entities have substantially overlapping individual controlling persons, each of the Funds, the Control Entities and the Dual Managers may be deemed to share the power to direct the disposition and vote of the Firm Shares.

The percentages set forth on the cover sheet for each of the Funds, Control Entities and the Dual Managers are calculated based on 105,012,566 shares, which includes (i) the 10-K Shares and (ii) the 16,115,887 shares of Common Stock into which the Firm Shares are convertible. The percentage set forth on the cover sheet for Barrett and Kerins is calculated based on 101,576,649 shares, which includes (i) the 10-K Shares and the (ii) 12,679,970 shares of Common Stock into which the NEA 14 Class B Shares are convertible.  The percentage set forth on the cover sheet for Makower and Sakoda is calculated based on 92,332,596 shares, which includes (i) the 10-K Shares and the (ii) 3,435,917 shares of Common Stock into which the NEA 15 Class B Shares and NEA 15-OF Class B Shares are convertible.

 (b) Regarding the number of shares as to which such person has:

(i) sole power to vote or to direct the vote: See line 7 of cover sheets

(ii) shared power to vote or to direct the vote: See line 8 of cover sheets

(iii) sole power to dispose or to direct the disposition: See line 9 of cover sheets

(iv) shared power to dispose or to direct the disposition: See line 10 of cover sheets.

(c) Except as set forth in Item 3 above, none of the Reporting Persons has effected any transaction in the Common Stock during the last 60 days.

(d) No other person is known to have the right to receive or the power to direct the receipt of dividends from, or any proceeds from the sale of, Common Stock beneficially owned by any of the Reporting Persons.

(e) Not applicable.
