FOR IMMEDIATE RELEASE

OLD SECOND BANCORP, INC. TO ACQUIRE HERITAGEBANC, INC.

Aurora, Illinois (November 6, 2007) – Old Second Bancorp, Inc. (Nasdaq: OSBC) and HeritageBanc, Inc. today announced an agreement to merge HeritageBanc, Inc. into Old Second Bancorp, Inc., and to merge Heritage Bank, Heritage’s bank subsidiary, into Old Second National Bank, adding $350 million dollars in assets and 5 branches, creating a pro forma 35-branch bank with more than $3 billion in assets.

“This transaction provides us with the platform to expand our franchise into the desirable, higher-growth markets of the south Chicago suburbs. It also allows us to fill in our footprint surrounding the Chicago metropolitan area,” said William B. Skoglund, Chairman, President and Chief Executive Officer of Old Second Bancorp, Inc. “With our similar relationship-focused banking strategies, we’ll also have the opportunity to provide Heritage’s loyal customers with the wealth management services, and expanded mortgage, treasury and retail services that Old Second is able to offer.”

John Ladowicz, Chairman and Chief Executive Officer of Heritage, will join Old Second Bancorp’s board of directors and Patrick Roe, President and Chief Operating Officer of Heritage, will join Old Second Bank as Senior Vice President - Regional Manager overseeing Heritage’s market region. “The addition of talented and service-oriented commercial bankers is another clear benefit of this transaction. Heritage’s management team and board have built and run a strong organization with a solid record of asset quality and client service, and Pat Roe, President of Heritage Bank, looks forward to leading his team of bankers as they join forces with Old Second. We have further solidified these relationships by entering into retention arrangements with the executive management team of Heritage through Old Second’s long term incentive compensation plans,” Skoglund added.

“Our team is thrilled to merge with such a reputable and community-focused institution,” Ladowicz said on behalf of Heritage. “Along with an unwavering commitment to the communities it serves, Old Second has a rich history of providing unequalled client care and solutions, and returns for its shareholders. This partnership will enable us to provide a multitude of new products and services to our clients, while contributing to the strength and vitality of the communities Heritage serves,” he concluded.

The $86 million purchase of HeritageBanc, Inc. will include common shares of Old Second Bancorp and cash. Heritage shareholders may elect to exchange each share held for either cash, or shares of Old Second Bancorp, equating to approximately $10,333 per share, based upon Heritage’s outstanding 8,323 shares. Elections may be subject to pro-ration if the results of aggregate elections differ from the prescribed cash-stock split of 50%/50%. The

exchange ratio of Old Second shares for Heritage shares will be calculated based upon the volume-weighted average price of Old Second Bancorp’s common shares over the 30 trading day period ending on the third trading day before closing, subject to certain limitations described in the definitive agreement. Based upon the volume-weighted average price of Old Second Bancorp’s common shares over the 30-trading day period ending on November 2, 2007 of $28.81, approximately 1.49 million common shares of Old Second Bancorp would be issued in the merger. The transaction is expected to close either late in the first quarter or early in the second quarter of 2008, pending approval by applicable regulatory agencies and the Heritage shareholders.

Heritage engaged Stifel, Nicolaus & Company, Inc as its sole financial advisor, with Paul O’Connor serving as lead banker and Barack Ferrazzano Kirschbaum & Nagelberg LLP.
