FREQUENTLY ASKED QUESTIONS REGARDING EQUITY AWARD TREATMENT IN IPG TRANSACTION

FOR AMS EMPLOYEES IN CHINA

Acxiom Corporation, the parent company of Acxiom Greater China Information Services, Ltd. (“Acxiom-SH”), has entered into a definitive agreement with The Interpublic Group of Companies, Inc. (“IPG”) pursuant to which the Acxiom Marketing Solutions (“AMS”) business of the Acxiom group of companies will be sold to IPG.

At or about the same time, Acxiom Corporation (which operates the LiveRamp business) has entered into an agreement and plan of merger with High Garden Merger Sub, Inc. and Acxiom Holdings, Inc. whereby Acxiom Holdings, Inc. will become the new parent company of the Acxiom group of companies and the remaining LiveRamp business.

Immediately prior to the time of Closing:

As you may know, Acxiom-SH has registered the Plan with the State Administration of Foreign Exchange (“SAFE”) so that the Plan can be offered in China and you can receive funds related to the Plan (e.g., sale proceeds) in compliance with SAFE regulations.

Following the Closing, Acxiom-SH will have a limited period of time (generally, 20 business days) in which to de-register the Plan with SAFE as it will not be eligible to maintain the registration once it is no longer a part of the Acxiom group of companies.

As a result, you will not be eligible to hold any Acxiom shares. If you were to hold Acxiom shares after Acxiom-SH de-registers the Plan with SAFE, there would not be a legal way for you to receive any funds related to such shares (e.g., sale proceeds) in China and it would be a violation of the SAFE regulations to keep any funds outside of China.

Therefore, you must sell any Acxiom shares you hold, including any shares you receive from the acceleration of the RSUs at Closing, as soon as possible following the Closing but in no event later than October 10, 2018.

You will receive a notice from Sasa Zhang once the Closing has occurred.

You can sell any Acxiom shares you currently hold at any time (subject to any applicable insider trading policy or applicable law).

At the latest, you must sell your shares by October 10, 2018 to allow Acxiom-SH sufficient time to repatriate the funds to China and complete all the necessary procedures prior to de-registering the Plan.

If you do not sell your shares by October 10, 2018, your shares will be automatically sold on your behalf on or after October 12, 2018.

You will receive notification from the designated broker for the Plan, E*TRADE, when the sale has occurred.

You must sell your shares by contacting the designated broker for the Plan, E*TRADE.

You should contact E*TRADE to find out about how you can sell your shares in these circumstances.

Alternatively, if you do not instruct E*TRADE to sell your shares by October 10, 2018, your shares will be automatically sold on your behalf on or after October 12, 2018 as described above.

As is the usual practice when Acxiom shares are sold:

If you have not already provided the details of your personal bank account to Acxiom-SH in order to receive sale proceeds from HSBC, you will need to do so by completing the information on the acknowledgement page below.

2

The LiveRamp business will remain part of the Acxiom group of companies and the LiveRamp entity in China will be eligible to register the Plan with SAFE. Therefore, employees who are part of the LiveRamp business will not be required to sell their Acxiom shares and the vesting of their RSUs will not be accelerated at the Closing.

Please sign and return the attached acknowledgement form to Acxiom-SH by September 20, 2018. Please also provide your bank account details to receive your sale proceeds, if not previously provided.

If you have any questions about this process, please contact Sasa Zhang ([REDACTED]).

FREQUENTLY ASKED QUESTIONS REGARDING EQUITY AWARD TREATMENT IN REORGANIZATION TRANSACTIONS

FOR LR EMPLOYEES IN CHINA

Acxiom Corporation, the parent company of Acxiom Asia Global Service Center Ltd. (“Acxiom-NG”), has entered into a definitive agreement with The Interpublic Group of Companies, Inc. (“IPG”) pursuant to which the Acxiom Marketing Solutions (“AMS”) business of the Acxiom group of companies will be sold to IPG. Part of the AMS business includes Acxiom Greater China Information Services, Ltd. (“Acxiom-SH”), another subsidiary of Acxiom Corporation in China.    

At or about the same time, Acxiom Corporation (which operates the LiveRamp business) has entered into an agreement and plan of merger with High Garden Merger Sub, Inc. and Acxiom Holdings, Inc., whereby Acxiom Holdings, Inc. will become the new parent company of the Acxiom group of companies and the remaining LiveRamp business.

Acxiom-NG will change its name to LiveRamp China (“LR China”), likely sometime in October 2018.

After the Closing, LR China (along with other parts of the LiveRamp business) will remain part of the Acxiom group of companies while Acxiom-SH (along with other parts of the AMS business) will no longer be part of the Acxiom group of companies.

These transactions are expected to be effective on or about October 1, 2018 (the “Closing”).

Immediately prior to the time of Closing:

All of your existing shares of Acxiom Corporation will be automatically converted into shares of Acxiom Holdings, Inc. These shares will be held in the same E*TRADE account where your Acxiom shares are currently held and will be subject to the same procedures upon sale of the shares.

As you may know, the Plan was registered with the State Administration of Foreign Exchange, Shanghai branch (“Shanghai SAFE”) by Acxiom-SH, and you receive the funds related to the Plan (e.g., sale proceeds) in China through a special bank account that Acxiom-SH has established at HSBC, Shanghai branch (“HSBC Shanghai”).

1

[For LR Employees]

Following the transaction, Acxiom-SH will need to de-register the Plan with Shanghai SAFE, and close its special bank account at HSBC Shanghai. Acxiom-NG does not currently have its own registration with Shanghai SAFE or a separate bank account with HSBC Shanghai, so it will need to re-register the Plan with SAFE, Nantong branch (“Nantong SAFE”), and establish a new, special bank account with a designated bank in China (the “Designated Bank”).

It is currently anticipated that it will take approximately 2-4 months to (i) close the account with HSBC Shanghai, (ii) de-register the Plan with Shanghai SAFE, (ii) re-register the Plan with Nantong SAFE, and (iii) establish a new bank account with the Designated Bank. Once the HSBC Shanghai account is closed, no funds related to the Plan can be received in China until a new account with the Designated Bank has been established by Acxiom-NG / LR China.

It is anticipated that the HSBC Shanghai account will be closed sometime before November 1, 2018. However, the exact date depends on various factors. The new account at the Designated Bank cannot be opened until the Plan has been registered with Nantong SAFE. The exact date depends on various factors and it is not anticipated to be opened until sometime in early 2019.

The RSUs will vest as usual during this time and you will be taxed on the value of the shares issued at vesting. Taxes will be withheld from payroll (or by any other method permitted under the Plan and applicable law), per the usual process on vesting of RSUs.

You will still be able to sell your shares during this time (subject to any applicable insider trading policy or applicable law). However, you will not be able to receive proceeds once the HSBC Shanghai account is closed and until Acxiom-NG / LR China has registered the Plan with Nantong SAFE and opened a new account with the Designated Bank. As noted above, the new account with the Designated Bank might not be available to receive funds until early next year.

You should also note that you will still be subject to tax when you sell your shares, even if you cannot receive the proceeds, and taxes will be withheld from payroll (or by any other method permitted under the Plan and applicable law), per the usual process on sale.

We cannot advise you on the best time to sell your shares. However, if you sell shares after October 12, 2018, it is unlikely that you will be able to receive any sale proceeds until the Plan has been re-registered with Nantong SAFE, and the new account with the Designated Bank has been established and can receive and disburse such funds.

2

[For LR Employees]

You will receive a notice from LiveRamp US or LR China once the registration has been completed and the Acxiom-NG / LR China special bank account is opened.

Because Acxiom-SH will no longer be part of the Acxiom group of companies and has to de-register the Plan with Shanghai SAFE, as described above, employees of Acxiom-SH will no longer be eligible to hold any Acxiom shares and they must sell such shares as soon as possible after the completion of the sale of the AMS business.

Please sign and return the attached acknowledgement form to Acxiom Asia Global Service Center Ltd. by September 20, 2018.

If you have any questions about this process, please contact Sasa Zhang ([REDACTED]).
