Exhibit 10.1

AMERUS GROUP CO.

FIRST AMENDMENT

     FIRST AMENDMENT (this “Amendment”), dated as of October 30, 2006, among AMERUS GROUP CO. (the “Borrower”), the lenders party to the Credit Agreement referred to below (the “Banks”) and JPMORGAN CHASE BANK, N.A., as Administrative Agent under the Credit Agreement (the “Administrative Agent”). Capitalized terms used herein without definition shall have the same meanings herein as set forth in the Credit Agreement.

RECITALS

     WHEREAS, the Borrower, the Banks and the Administrative Agent are party to an Amended and Restated Credit Agreement, dated as of June 16, 2006 (as amended, supplemented or otherwise modified to, but not including, the date hereof, the “Credit Agreement”).

     WHEREAS, Aviva plc (“Aviva”) intends to acquire all of the outstanding capital stock of the Borrower (the “Aviva Transaction”).

     WHEREAS, the Aviva Transaction constitutes a Change of Control under the Credit Agreement, and if consummated would result in an Event of Default under Sections 8.03 (as a result of a violation of Section 7.02) and 8.09 of the Credit Agreement.

     WHEREAS, the Borrower desires that the credit facility continue to be available following completion of the Aviva Transaction and has therefore requested the Banks to waive the above referenced Events of Default by agreeing to certain amendments to the Credit Agreement.

     WHEREAS, the Borrower desires to modify its obligations under the Credit Agreement requiring the delivery of financial statements that comply with, and compliance with certain covenants calculated in accordance with, GAAP, and in the alternative to require, respectively, compliance with and calculations in accordance with, IFRS (the “Accounting Change”).

     WHEREAS, the Borrower desires to modify the audit requirements of Section 6.01(a)(i) with respect to the annual financial statements to be delivered thereunder and in the alternative to require delivery of an accountants report in an agreed form.

     NOW, THEREFORE, in consideration of the premises and the agreements, provisions, and covenants herein contained, the parties hereto agree as follows:
