Recommended Steps to Help Protect Your Information

1. Telephone. Contact IDX at 1-888-201-3629 to gain additional information about this event and speak with
   knowledgeable representatives about the appropriate steps to take to protect your credit identity.

2. Review your credit reports. We recommend that you remain vigilant by reviewing account statements and
   monitoring credit reports. Under federal law, you also are entitled every 12 months to one free copy of your credit report from each of the three major credit reporting companies. To obtain a free annual credit report, go to www.annualcreditreport.com or call 1-877-322-8228. You may wish to stagger your requests so that you receive a free report by one of the three credit bureaus every four months.

3. Report suspicious activity. You have the right to file a police report if you ever experience identity fraud. Please
   note that in order to file a crime report or incident report with law enforcement for identity theft, you will likely need to provide some kind of proof that you have been a victim. A police report is often required to dispute fraudulent items. You can report suspected incidents of identity theft to local law enforcement or to the Attorney General.

4. Place Fraud Alerts with the three credit bureaus. If you choose to place a fraud alert, we recommend you do this
   after activating your credit monitoring. You can place a fraud alert at one of the three major credit bureaus by phone and also via Experian’s or Equifax’s website. A fraud alert tells creditors to follow certain procedures, including contacting you, before they open any new accounts or change your existing accounts. For that reason, placing a fraud alert can protect you, but also may delay you when you seek to obtain credit. The contact information for all three bureaus is as follows: Credit Bureaus Equifax Fraud Reporting Experian Fraud Reporting TransUnion Fraud Reporting 1-866-349-5191 1-888-397-3742 1-800-680-7289 P.O. Box 105069 P.O. Box 9554 P.O. Box 2000 Atlanta, GA 30348-5069 Allen, TX 75013 Chester, PA 19022-2000 www.equifax.com www.experian.com www.transunion.com It is necessary to contact only ONE of these bureaus and use only ONE of these methods. As soon as one of the three bureaus confirms your fraud alert, the others are notified to place alerts on their records as well. You will receive confirmation letters in the mail and will then be able to order all three credit reports, free of charge, for your review. An initial fraud alert will last for one year. Please Note: No one is allowed to place a fraud alert on your credit report except you.

5. Security Freeze. By placing a security freeze, someone who fraudulently acquires your personal identifying
   information will not be able to use that information to open new accounts or borrow money in your name. You will need to contact the three national credit reporting bureaus listed above to place the freeze. Keep in mind that when you place the freeze, you will not be able to borrow money, obtain instant credit, or get a new credit card until you temporarily lift or permanently remove the freeze. There is no cost to freeze or unfreeze your credit files.

6. You can obtain additional information about the steps you can take to avoid identity theft from the following
   agencies. The Federal Trade Commission also encourages those who discover that their information has been misused to file a complaint with them.
