Stock Investment Plan

We maintain a Stock Investment Plan for the purchase of common stock, which allows persons who are not already shareholders to become participants by making a minimum initial cash investment of $100. Our Plan enables you to maintain registration with us in your own name rather than with a broker in “street name.”

The Stock Investment Plan also provides you with options for reinvesting your dividends and making optional cash purchases of common stock directly through the Plan without paying brokerage commissions, fees, or service charges. Optional cash payments of not less than $25 per payment may be made subject to a maximum of $100,000 per calendar year. An automatic investment option allows you to authorize the deduction of payments from your checking or savings account automatically once each month, on the third day of the month, by electronic means for investment in the Plan.

Cash for investment must be received by the 3rd or 18th day of the month. Investment generally commences on or about the 5th or 20th day of the month, or as soon thereafter as practicable.

The shares you hold in our Stock Investment Plan may be sold by the agent for the Plan as you direct us, or you may request a stock certificate for sale through a broker you select. We will accumulate sale requests from participants and, approximately every five business days, will submit a sale request to the independent broker-dealer on behalf of those participants.

Participation in the Stock Investment Plan is being offered only by means of a prospectus. If you would like a copy of the Stock Investment Plan prospectus, you may use the American Stock Transfer & Trust Company, LLC website at www.amstock.com, call American Stock Transfer & Trust Company, LLC at 800- 236-1551, contact us by sending an e-mail to investor@integrysgroup.com, or download the prospectus and enrollment forms. from our website under “Stock Investment Plan.”
