Protection One Stock Commences Trading on Nasdaq® Global Market

under new “PONE” Symbol Effective Today

LAWRENCE, Kan. and ALBANY, N.Y. — April 2, 2007 — Protection One, Inc. (NASDAQ: PONE, previously OTCBB: PONN) and Integrated Alarm Services Group (NASDAQ: IASG) today announced the closing of their previously announced merger, pursuant to which IASG will merge with a wholly owned subsidiary of Protection One.

In addition, today, Protection One stock ceased trading on the OTC Bulletin Board and commenced trading on the Nasdaq® Global Market. With its move to Nasdaq, Protection One’s trading symbol changed to PONE.

On March 27, 2007, IASG shareholders voted overwhelmingly in favor of the merger, which received 99.9% of the 17.7 million shares cast. Pursuant to the merger, shareholders of IASG will receive 0.29 shares of Protection One, Inc. common stock for each share of IASG common stock owned, plus cash for any fractional shares. Approximately 7.1 million shares of Protection One common stock will be issued resulting in a total of 25.3 million shares outstanding, of which IASG and Protection One shareholders will own approximately 28% and 72%, respectively.

Market Leadership and Financial Expectations

With the completion of the merger, Protection One assumes ownership of the nation’s No. 1 provider of wholesale alarm monitoring services, Criticom International, which will combine with Protection One’s wholesale monitoring provider, CMS, and will soon operate under a new name, Criticom Monitoring Services™ (also to be known as CMS).

Protection One also remains one of the nation’s largest providers of security alarm monitoring services to residential, commercial and national account customers, which will continue operating under the name Protection One®, as well as the largest provider to the multifamily market, operating under the name Network Multifamily®. In total, the merged company, which will remain based in Lawrence, Kansas, will have 73 branches across the country, six state-of-the-art monitoring response centers, and a dedicated disaster recovery center.

Management believes that larger scale operations, elimination of redundancies and greater purchasing power generated by this merger will, within 12 months, result in net savings of $11 million to $13 million on an annualized basis. On a combined basis, Protection One and IASG had revenues and adjusted EBITDA of $364.9 million and $106.0 million, respectively, for the 12-month period ended Dec. 31, 2006 (with adjusted EBITDA being measured prior to the realization of any operating synergies).  As of Dec. 31, 2006, Protection One and IASG on a combined basis had recurring monthly revenue (“RMR”), a well known valuation metric used for monitoring services companies, of $26.9 million.

Richard Ginsburg, President and CEO of Protection One, said, “Our successful completion of this merger paves the way to create a leading security monitoring services company with a diversified portfolio of security assets. It is a logical step for both Protection One and IASG and one that we believe will create value for shareholders, enhanced services for our customers and a growing company, with many new opportunities, for our employees. I would also like to thank IASG’s shareholders for supporting the merger so decisively.”

Ginsburg continued, “Given our team’s track record of overcoming challenges brought on by rapid growth through acquisitions and of completing a successful restructuring, we are confident that we, along with the many talented IASG employees who are joining us, can execute our plan to take the combined company forward and reach new levels of success. We can now begin work on our important goals of increasing customer retention and of improving operating performance by taking advantage of synergies that allow us to increase EBITDA, and, again, create value for our shareholders. For our valued retail, wholesale and multifamily customers, we are excited to offer an unmatched network of central stations and the infrastructure to further enhance our product and service offerings. We are optimistic that the clients of our wholesale business, which will continue to operate separately from our retail side, will respond well to our new monitoring capabilities, expanded service offerings and a renewed focus on dealer support.”

Charles May, President and CEO of IASG, said, “Like other IASG shareholders, I look forward to Richard and his team delivering the many potential benefits of this merger.  I know I speak for the Board of IASG in wishing the new company much success.”

The companies will begin merging operations today, with a transition period occurring before IASG residential and commercial customers will begin seeing the Protection One name as their service provider and before Protection One will begin servicing or billing customers.  In addition, Criticom dealers will soon receive information about the specific benefits of this merger for them. More information about what this merger means for customers can be found on the companies’ respective Web sites.
