On July 18, 2006, AmerUs Group Co. posted the following article on its internal website, which discusses changes to be made in the AmerUs Group Co. retirement plans.


Changes in the Investment Line-up for the AmerUs Retirement Plans

On Thursday, July 13, 2006 we announced AmerUs Group and Aviva plc signed a definitive agreement under which Aviva will acquire AmerUs Group for $69 per share in cash for all outstanding shares of AmerUs Group common stock. Whenever a transaction like this is announced, companies’ stock prices reflect investors’ beliefs about the transaction. As a result, our stock price may fluctuate during the transition period.


AmerUs Group’s Company Stock Fund

It is customary in the acquisition of a publicly-traded company for employees to have the option to retain or transfer the company stock assets they hold in their retirement plans. It is also customary to limit employees from adding to their holdings of company stock in their retirement plans when a deal such as the Aviva deal is pending. AmerUs Group has chosen to implement this guiding principle immediately. As a result, you have the option to hold or transfer-out of your holdings in the AmerUs Group’s Company Stock Fund within your All*AmerUs Savings & Retirement Plan, Excess Benefit Plan and Supplemental Executive Retirement Plan (SERP) (the “Plans”).


Since you do not have the option to increase assets in this fund, no new monies can be invested. Therefore, you may want to change your future investment allocation. If you do not make a change, any payroll deductions to the Company Stock Fund will be invested in the default fund (American Century Stable Asset Fund in the 401(k) and American Century Premium Money Market -Investment Fund in the Excess Benefit Plan and SERP) beginning with the July 28, 2006 payroll.


To transfer existing assets or make changes to future investment allocations access www.retireonline.com or call the J.P. Morgan Retirement Plan Services InfoLine at 1-800-345-2345.



There are two sets of rules governing amounts invested in AmerUs Group common stock – one for the Company Stock Fund and one for the ESOP Fund. Assets in the ESOP Fund are locked-in and generally may not be transferred or reinvested in any other investment fund.


Reminder on all Company Stock Purchases

Keep in mind that the AmerUs Group Insider Trading and Confidentiality Policy states no director, officer or employee who has material non-public information relating to the Company may buy or sell securities of the Company on the open market or through the Plans, as defined in the policy. As a result, trading or transferring AmerUs Group common stock in the Plans may be restricted, unless pre-cleared with Jim Smallenberger, senior vice president and corporate secretary, or Chris Littlefield, executive vice president and general counsel.





When the Transaction is Completed

When the transaction with Aviva is completed, assets in AmerUs Group Common Stock and ESOP Funds will be converted to cash. You will then have the opportunity to reallocate the proceeds from the sale of your AMH stock into any of the other investment choices available.


You are encouraged to review your investment allocations and make changes as necessary. If you have questions, please contact the AmerUs Service Center at 1-877-AmerUs-4-U (1-877-263-7874).


The foregoing does not constitute investment advice. You should consult your investment advisor prior to making any changes in your investments.

Cautionary Statement Regarding Forward-Looking Statements


This document contains statements which constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, which include words such as “anticipate,” “believe,” “plan,” “estimate,” “expect,” “intend,” and other similar and related expressions. Forward-looking statements are made based upon management’s current expectations and beliefs concerning future developments and their potential effects on AmerUs



Group. Such forward-looking statements are not guarantees of future events. Actual results may differ materially from those contemplated by the forward-looking statements due to, among others, the following factors: (1) the shareholders of AmerUs Group may not approve and adopt the merger agreement and the transactions contemplated by the merger agreement at the special shareholder meeting; (2) the parties may be unable to obtain governmental and regulatory approvals required for the merger, or required governmental and regulatory approvals may delay the merger or result in the imposition of conditions that could cause the parties to abandon the merger; (3) the parties may be unable to complete the merger because, among other reasons, conditions to the closing of the merger may not be satisfied or waived; or (4) other factors that may be referred to in AmerUs Group's reports filed with or furnished to the Securities and Exchange Commission from time to time. There can be no assurance that other factors not currently anticipated by AmerUs Group will not materially and adversely affect future events. Security holders are cautioned not to place undue reliance on any forward-looking statements made by AmerUs Group or on its behalf. Forward-looking statements speak only as of the date the statement was made. AmerUs Group undertakes no obligation to update or revise any forward-looking statement.
