This Current Report on Form 8-K relates to three agreements between or among certain subsidiaries of State Auto Financial Corporation (“State Auto Financial”), State Automobile Mutual Insurance Company (“State Auto Mutual”), and certain subsidiaries and affiliates of State Auto Mutual. State Auto Mutual owns approximately 64% of the outstanding common shares of State Auto Financial.

2010 Pooling Agreement

Since 1987, State Auto Mutual and State Auto Property & Casualty Insurance Company (“State Auto P&C”) have participated in an intercompany pooling arrangement which has been amended from time to time, including amendments to add participants to the pooling arrangement and to adjust pooling percentages.

On February 10, 2010, the Pooled Companies, as defined below, entered into the Reinsurance Pooling Agreement, Amended and Restated effective as of January 1, 2010 (the “2010 Pooling Agreement”). The 2010 Pooling Agreement amended the reinsurance pooling agreement in effect as of December 31, 2009.

The 2010 Pooling Agreement is among State Auto Mutual, State Auto P&C, Milbank Insurance Company (“Milbank”), State Auto Insurance Company of Wisconsin (“SA WI”), Farmers Casualty Insurance Company (“Farmers Casualty”), State Auto Insurance Company of Ohio (“SA OH”), State Auto National Insurance Company (“SAN”), State Auto Florida Insurance Company (“SA FL”), Meridian Security Insurance Company (“Meridian Security”), Meridian Citizens Mutual Insurance Company (“Meridian Citizens Mutual”), Patrons Mutual Insurance Company of Connecticut (“Patrons”), Litchfield Mutual Fire Insurance Company (“Litchfield”), and Beacon National Insurance Company (“Beacon”). State Auto Mutual, State Auto P&C, Milbank, SA WI, Farmers Casualty, SA OH, SA FL, Meridian Security, Meridian Citizens Mutual, Patrons, Litchfield and Beacon are collectively referred to as the “Pooled Companies.” State Auto P&C, Milbank, Farmers Casualty, SA OH and SAN are wholly owned subsidiaries of State Auto Financial. SA WI, SA FL, Meridian Security and Beacon are wholly owned subsidiaries of State Auto Mutual. Meridian Citizens Mutual, Patrons and Litchfield are affiliated with State Auto Mutual through affiliation agreements.

The 2010 Pooling Agreement made the following changes to the intercompany pooling arrangements in effect as of December 31, 2009:

Under the terms of the 2010 Pooling Arrangement, the Pooled Companies cede all of their direct insurance business to State Auto Mutual. All of State Auto Mutual’s current property and casualty insurance business is also included in the pooled business. State Auto Mutual then cedes a percentage of the pooled business to the other Pooled Companies and retains the balance. The allocated pooling percentages of the Pooled Companies as of January 1, 2010, were as follows: State Auto P&C – 59.0%; Milbank – 17.0%; Farmers Casualty – 3.0%; SA OH – 1.0%; SAN – 0.0%; State Auto Mutual – 19.0%; SA WI – 0.0%; SA FL – 0.0%; Meridian Security – 0.0%; Meridian Citizens Mutual – 0.5%; Beacon – 0.0%; Patrons – 0.4%; and Litchfield – 0.1%.

In the event that one of the Pooled Companies becomes insolvent or is otherwise subject to liquidation or receivership proceedings, State Auto Mutual will adjust its net retained portion of the combined Net Liabilities (as defined in the 2010 Pooling Agreement) of the Pooled Companies and the remaining Pooled Companies will adjust their assumed portions of the combined Net Liabilities of the Pooled Companies, each on a pro rata basis, so as to collectively absorb or assume in full the net retained portion of the combined Pooled Companies’ Net Liabilities of State Auto Mutual which would otherwise be the responsibility of such impaired company. In the event that State Auto Mutual becomes insolvent or is otherwise subject to liquidation or receivership proceedings, the remaining Pooled Companies will adjust their assumed portions, each on a pro rata basis, so as to collectively absorb or assume in full the net retained portion of the combined Pooled Companies’ Net Liabilities of State Auto Mutual which they had not previously assumed and which would otherwise be the responsibility of State Auto Mutual.

The 2010 Pooling Agreement remains in effect until canceled by the giving of 12 months advance notice by one of the parties to the other parties and to the respective domiciliary insurance department of each of the parties. Upon termination, all Net Liabilities of the terminated Pooled Company incurred under or in connection with all contracts or policies of insurance issued by the terminated Pooled Company prior to 12:01 a.m. EST on the date of termination remain subject to all terms and provisions of the 2010 Pooling Agreement; provided, however, if the terminated Pooled Company is not affiliated with State Auto Mutual on the date of termination, then the 2010 Pooling Agreement automatically and immediately terminates as to the terminated Pooled Company, all unpaid Net Liabilities of the terminated Pooled Company as of the date of termination are retroceded to the terminated Pooled Company.

On February 10, 2010, SAN and State Auto Mutual entered into a Commutation and Release Agreement, effective as of January 1, 2010 (the “SAN/SAM Commutation Agreement”). The parties entered into the SAN/SAM Commutation Agreement in connection with SAN being added as a participant to the pooling arrangement in accordance with the 2010 Pooling Agreement.

The Rockhill Companies reimburse State Auto P&C for salary expenses attributable to the State Auto P&C employees performing services for the Rockhill Companies based on an allocation of the time these individuals spend on behalf of the Rockhill Companies. In addition, the Rockhill Companies reimburse State Auto P&C for the expense of services provided to them by State Auto P&C, including without limitation, payroll taxes, benefits, overhead, and rent, based on a percentage of the aforesaid salary expenses, determined annually by State Auto P&C in an amount that reasonably reflects the actual costs of the aforesaid items. The Rockhill Companies’ share of pension and benefit expenses under the State Auto benefit plans provided for the State Auto P&C employees are allocated to the Rockhill Companies based on the percentage of State Auto P&C payroll expenses attributable to the Rockhill Companies.

Likewise, State Auto P&C and State Auto Mutual reimburse the Rockhill Companies for all costs and expenses incurred by the Rockhill Companies for the services provided to each of them based on an allocation of the time these individuals spend on behalf of each of State Auto P&C and State Auto Mutual. In addition, State Auto P&C and State Auto Mutual reimburse the Rockhill Companies for the expense of services provided to each of them by the Rockhill Companies, including without limitation, payroll taxes, pension and employee benefits, overhead, and rent, based on a percentage of the aforesaid salary expenses, determined annually by the Rockhill Companies in an amount that reasonably reflects the actual costs of the aforesaid items.

The Rockhill Management Agreement is for a ten-year term ending on December 31, 2019, and automatically renews for successive ten-year periods upon the same terms and conditions. Prior to the end of the initial term or any renewal term, any party may terminate the Rockhill Management Agreement as to such party by giving the other parties at least 60 days advance written notice of such termination. Such termination only relates to the company giving notice and does not terminate the agreement with respect to any of the other parties unless they also give at least 60 days advance written notice of termination. The agreement automatically terminates with respect to a party if that party files a voluntary petition in bankruptcy or takes similar action in any bankruptcy, liquidation, dissolution or reorganization proceeding.
