UNITED BANCORP, INC. COMPLETES REDEMPTION OF

50% OF OUTSTANDING SHARES OF PREFERRED STOCK

ANN ARBOR, MI – United Bancorp, Inc. (OTCQB:UBMI) announced today that it completed the redemption on September 30, 2013 of 10,300 shares, or 50%, of its 20,600 shares of outstanding Fixed Rate Cumulative Perpetual Preferred Stock, Series A ("Preferred Stock") that were originally issued to the United States Department of the Treasury ("U.S. Treasury") under the Troubled Asset Relief Program Capital Purchase Program. U.S. Treasury sold all 20,600 shares of Preferred Stock to private investors in June 2012. Following completion of the partial redemption, 10,300 shares of Preferred Stock remain outstanding.

The redemption price for the shares of Preferred Stock was the stated liquidation preference amount of $1,000 per share, plus any accrued and unpaid dividends to but excluding September 30, 2013. The total cost of the partial redemption of shares of Preferred Stock was approximately $10.4 million, which was funded with a combination of excess cash at the holding company, the dividend to the holding company of retained earnings at the Company’s subsidiary bank, United Bank & Trust (the "Bank"), and the borrowing of $6.0 million under the Company’s $10.0 million revolving line of credit. These sources of funding may also be available to fund the possible future redemption of the remaining shares of Preferred Stock. The partial redemption of shares of Preferred Stock will result in estimated annual savings of $660,000, or $0.05 per common share, due to the elimination of payment of dividends on the redeemed shares.

Following completion of the partial redemption of shares of Preferred Stock, the capital ratios of the Company and the Bank continue to exceed regulatory standards to be categorized as well-capitalized. In addition, the Bank's Tier 1 capital ratio continues to exceed the 8.5% level required by resolution of the Bank’s Board of Directors.
