Home Office Employee Share-Based Awards FAQ

1. I received a letter notifying me of my 2012 share-based award. What happens to this?

Do I receive a dividend equivalent on this award?

• 2012 Restricted Cash Units (2012 RCUs): The value of this award will be converted to a cash amount equal to the number of 2012 RCUs outstanding on the date the transaction closes times $51.50, which is the per-share cash amount to be paid for each share of Company Stock in the Tender Offer and Merger. This cash amount, less applicable withholding taxes, will be paid to you at the time the 2012 RCUs would have vested under the original award agreement terms relating to service-based vesting, provided you are still employed on that date except as otherwise set forth in your award agreement.

• 2012 Restricted Stock Units (2012 RSUs): The value of this award will be converted to a cash amount equal to the number of 2012 RSUs outstanding on the date the transaction closes times $51.50, which is the per-share cash amount to be paid for each share of Company Stock in the Tender Offer and Merger. This cash amount, less applicable withholding taxes, will be paid to you at the time the 2012 RSUs would have vested under the original award agreement terms relating to service-based vesting, provided you are still employed on that date except as otherwise set forth in your award agreement.

• 2012 Performance Based Restricted Stock Units (PBRSUs): The value of this award will be converted to a cash amount equal to the number of shares earned times $51.50, which is the per-share cash amount to be paid for each share of Company Stock in the Tender Offer and Merger. The number of shares earned will be calculated based on the extent to which the total shareholder return performance criteria set out in your award agreement have been satisfied on the tender offer closing date. This cash amount, less applicable withholding taxes, will be paid to you at the time the PBRSUs would have vested under the original award agreement terms relating to service-based vesting, provided you are still employed on that date except as otherwise set forth in your award agreement.

• Dividend Equivalents on 2012 Stock-Based Awards: The first quarter cash dividend of $0.275 per share was authorized by the Company's Board of Directors and will be paid on May 25th on all outstanding shares that are dividend eligible. All outstanding share-based awards that are dividend eligible shall participate in the first quarter cash dividend in accordance with the terms and conditions governing such share-based awards. In connection with this transaction, it is unlikely that the Company will pay any future cash dividends.

2. I have awards that were granted prior to 2012. What happens to these?

Do I continue to receive dividend equivalents?

For Awards granted prior to the 2012 Award:

• Restricted Cash Units granted prior to 2012 (RCUs): RCUs which are outstanding and unvested will become fully vested on the date the transaction closes. All outstanding RCUs as of the date the transaction closes will then be converted to a cash amount equal to the number of RCUs times $51.50, which is the per-share cash amount to be paid for each share of Company Stock in the Tender Offer and Merger. This cash payout, less applicable withholding taxes, will be paid to you within 10 business days after the merger transaction closes.

• Company Stock Options: All unvested Company Stock Options issued prior to 2012 which are outstanding as of the date that is 10 days prior to the date the transaction closes will accelerate vesting per the agreement. Any outstanding options that have not been exercised as of the date the merger transaction closes will be settled via a cash payment, if any, within 10 business days after that date. Such payment will equal to the product of

◦ (i) the excess, if any, of $51.50, which is the per-share cash amount to be paid for each share of Company Stock in the Tender Offer and Merger, over the per-share exercise price of your Company Stock Option, multiplied by

◦ (ii) the unexercised number of shares of Company Stock underlying your outstanding Company Stock Option.

• If the exercise price per share of your outstanding Company Stock Option is equal to or greater than $51.50, your Company Stock Option will be canceled and terminated without any cash payment when the merger transaction closes.

• The first quarter cash dividend of $0.275 per share was authorized by the Company's Board of Directors and will be paid on May 25th on all outstanding shares that are dividend eligible. All outstanding share-based awards that are dividend eligible shall participate in the first quarter cash dividend in accordance with the terms and conditions governing such share-based awards. In connection with this transaction, it is unlikely that the Company will pay any future cash dividends.
