DUBLIN, OH, November 15, 2010 -- National Investment Managers (OTC BB: NIVM), a nationally-based and regionally-operated retirement plan administration and investment management company, with over $11 billion of assets under administration, today announced that it has entered into a non-binding letter of intent, with exclusivity provisions, for the sale of the company to an entity to be formed by Stonehenge Partners, Inc. for $48 million in cash, subject to a negotiated net working capital target. Stonehenge Partners, Inc., based in Columbus, Ohio, manages more than $600 million of private capital and focuses on investing in middle-market businesses.

Completion of the sale is subject to certain terms and conditions, including the negotiation and execution of a mutually satisfactory definitive acquisition agreement, completion of financing arrangements and due diligence by Stonehenge, and requisite approvals from the Company’s senior and subordinated senior lenders and shareholders. The parties are working toward the execution of a definitive agreement by year-end, assuming all conditions in the letter of intent are satisfied by the required time lines.

After payment of NIVM's outstanding debt, transaction expenses and certain other liabilities currently estimated to aggregate approximately $35 – 36 million and after giving effect to any required working capital adjustment, the remainder of the purchase price would be allocated among the holders of each series of NIVM's preferred stock and the holders of its common stock.

Steven J. Ross, Chief Executive Officer of National Investment Managers, said, "Our focus during the third quarter was to work with Carl Marks to continue the execution of a well-defined process toward a refinancing of debt or sale of the Company. While a significant amount of management time has been spent on that initiative, our field personnel met or exceeded all client deliverables which allowed the Company to post very positive results for the quarter. These results clearly demonstrate the strength and stability of our business model, and are a credit to the exceptional capabilities of our organization.”

John M. Davis, President and Chief Operating Officer, added, “I am proud of all of our people who have worked so hard to deliver early on nearly every client commitment for our calendar year plans. Our third quarter results were clearly buoyed by the completion of work well in advance of the October 15th filing deadline for Form 5500s. Due to anticipated delays associated with the newly required EFAST2 electronic filing process, we made a company-wide decision to accelerate our filings to avoid potential issues, and our people delivered. Our year-to-date results were slightly down from 2009 due to lower EGTRRA restatement revenue for defined contribution plans, which was expected with the completion of the restatement cycle for those plans in April, 2010.”

He concluded, “Great companies are built on a foundation of great people. And, despite the difficult economy, general business conditions, and the distractions associated with the recapitalization initiative, our people and our entire organization have continued to persevere. We’ve delivered upon every client commitment with superior service, and at the same time, continued to stay on track with our strategic and operational plans toward the development and implementation of our national technology platform and administrative business model across the country. As such, our people have been required to wear many hats, but we’ve accomplished a great deal as a team, and together we look forward to establishing NIVM as the premier retirement services company on a national level.”
