Excerpt from Tableau Employees Frequently Asked Questions

RESTRICTED STOCK UNITS (RSUS)

Any Tableau restricted stock units (RSUs) that are unvested as of the closing date would convert into Salesforce RSUs equal to the product obtained by multiplying (x) the number of Tableau unvested RSUs by (y) 1.103 (the Exchange Ratio), with any fractional shares rounded to the nearest whole share.

Example:

The outstanding and unvested RSUs are otherwise be subject to the same terms and conditions applicable to the corresponding RSU, including vesting terms.

Note: this same conversion process would apply to any shares of Tableau common stock that you currently own, whether acquired by an RSU vest, ESPP purchase or otherwise, except that fractional shares will be cashed out instead of rounded to the nearest whole share.

STOCK OPTIONS

Tableau stock options were mainly issued to employees prior to Tableau becoming a public company in May 2013 (so this does not apply to a majority of employees). Any Tableau stock options that are outstanding and unexercised (whether vested or unvested) on the closing date would convert to a number of Salesforce stock options equal to the product obtained by multiplying (x) the number of Tableau shares outstanding under the stock option by (y) 1.103 (the Exchange Ratio),with any fractional shares rounded down to the nearest whole share. The exercise price for the Salesforce stock option would be equal to the per share exercise price of the converted Tableau stock option divided by 1.103 (the Exchange Ratio), rounded up to the nearest whole cent.

The outstanding stock options are otherwise be subject to the same terms and conditions applicable to the corresponding Tableau stock option, including vesting and expiration terms. If you have stock options and have additional questions – you can contact our Stock Team at stock@tableau.com.

If you terminate employment prior to the closing date but still hold options for any reason as of the closing, your options will not convert into Salesforce stock options and you will receive a communication prior to closing describing how your options will be treated.

EMPLOYEE STOCK PURCHASE PLAN (ESPP)

If you are currently enrolled in Tableau’s ESPP, contributions will continue to be collected. The ESPP purchase date is currently scheduled to occur on November 30. As provided in the Agreement of Merger, if the closing date occurs prior to November 30, 2019, that purchase date will be accelerated to a date prior to the closing date. Of course, if you choose to withdraw your funds prior to the ESPP purchase date, all funds collected will be returned to you in the payroll period following your withdrawal. Post-closing, the Tableau ESPP would terminate.

More information will follow at a later date regarding any update on the purchase date for Tableau’s ESPP as well as any information regarding Salesforce ’s ESPP and its enrollment process.

TABLEAU’S TRADING POLICY

Trading Windows

We are currently in our usual blackout period, as we move forward to finish up the second quarter.

Our trading policy provides that the next trading window would open at the start of the 3rd full trading day following the date of public disclosure of the financial results for the second quarter. If the closing date occurs prior to such public disclosure, we would then operate under the Salesforce trading policy and trading window.

More information will follow at a later date regarding Salesforce’s trading policy.

Trading in Other Public Company Stock

At Adam’s initial all-hands update, there was a question raised about buying stock in other public companies, including Salesforce. Our trading policy does not prevent you from trading in any other public company stock, so long as you are not in possession of material, non-public information about that company or otherwise considered an insider of that company. It is each individual employee’s responsibility to ensure they are not in possession of material, non-public information about a company prior to placing a trade.

As noted above, as more information becomes available, we will update these FAQs. If you have specific questions that that are stock related, you can direct to our Stock team at stock@tableau.com
