TubeMogul Employee Frequently Asked Questions

1. What is a “tender offer”?

Through a tender offer, a bidder makes a public offer directly to a company’s stockholders to purchase their company shares for cash, stock or a combination of both. In our case, Adobe Systems Incorporated, through a subsidiary, Tiger Acquisition Corporation (“Purchaser”), is offering to buy all outstanding shares of common stock of TubeMogul (the “Offer”). During the Offer, TubeMogul stockholders will have an opportunity to “tender” their shares to Adobe in exchange for $14.00 per share in cash, without interest and subject to any required tax withholding.

2. Should I tender my Shares? How do I do that?

The TubeMogul Board of Directors unanimously approved the transaction and recommends that stockholders tender their shares into the Offer. All TubeMogul stockholders will separately receive additional information regarding the terms of the Offer and instructions on how to tender their shares. All TubeMogul stockholders should carefully read the information sent to them.

3. When will the transaction close?

The closing of the Offer is still subject to the tender of a majority of TubeMogul’s outstanding common stock to Adobe and other offer conditions, including government regulatory approvals. We expect the Offer to close during Adobe’s Q1 2017, which is between December and February.

4. What can I expect between now and closing?

Until the transaction closes, TubeMogul will continue to operate as a separate, independent company. TubeMogul’s employee salaries, compensation and benefits will not change through closing.

5. What will happen to my TubeMogul RSUs and stock options at closing?

The Offer is being made only for outstanding shares of TubeMogul common stock. Holders of outstanding exercisable stock options or RSUs may participate in the Offer only if they first exercise such stock options or become vested in such RSUs in accordance with the terms of the applicable stock plan and other applicable agreements, and then tender the shares of common stock issued upon such exercise or such vesting and settlement. Any such exercise or settlement should be completed prior to the end of the Offer period to assure that you will have sufficient time to comply with the procedures for tendering your shares.

Unvested RSUs and unvested stock options continue to vest according to their current vesting schedule. As of the closing of the merger, any unvested RSUs and unvested stock options held by anyone who is a current employee of TubeMogul as of the effective time of the merger (“Current Employee”) will convert into Adobe stock awards based on an exchange rate specified in the merger agreement.

Any vested, but unreleased RSUs and vested, but unexercised options held by a Current Employee will automatically be converted into the right to receive payment. For vested, but unreleased RSUs, the payment amount will be an amount equal to the number of issuable RSUs multiplied by $14.00. For vested, but unexercised stock options, the payment will be an amount equal to the difference between $14.00 and the applicable option exercise price, multiplied by the number of exercisable shares. If the exercise price per share of any stock option equals or exceeds $14.00 per share, such stock option will automatically be cancelled, without any payment to the holder.

All payments will be subject to applicable withholding taxes and will be made as soon as reasonably practicable after the closing date. As we get nearer to the closing, you will receive additional information.

6. What will happen to my ESPP contributions for the current purchase period that began on August 17, 2016?

The TubeMogul ESPP remains the same through the effective time of the Merger. One business day prior to the closing of the Merger, amounts you have contributed into your ESPP plan account will be used to purchase shares of TubeMogul common stock. At closing, your purchased shares will be cancelled and automatically converted into the right to receive an amount equal to the number of purchased shares multiplied by $14.00, subject to applicable withholding taxes.
