The following communications are being filed in connection with the acquisition of MuleSoft, Inc. by salesforce.com, inc.

Interview of salesforce.com, inc. President and Chief Product Officer Bret Taylor with Bloomberg L.P., dated March 22, 2018

BLOOMBERG: Now this announcement that you’ve agreed to buy MuleSoft for six and a half billion dollars; what can we read into it, because it seems to be a desire to stretch beyond Salesforce’s core customer relationship management tools.

BRET TAYLOR: You know so, if you think about what it means to transform a company that wasn’t born in the digital era…this digital transformation we fundamentally think it starts and ends with the customer, even if that means transforming a bunch of your legacy systems. And the reason why we’re so interested in MuleSoft and this concept of sort of integrating all these legacy systems, is that it really unlocks the data from legacy systems to enable people to participate in all these amazing new experiences that we’re seeing on our phones and our watches with customer service experiences that are really transforming business today. So I do think MuleSoft’s platform is amazing because it really enables companies to kind of turbocharge their digital transformation. And for Salesforce specifically it means that they can transform their customer experiences faster, which is really our mission.
