MAI Systems Corporation Reports Debt Restructuring

Lake Forest, CA (September 29, 2005)... MAI Systems Corporation (MAIY.PK) announces that HIS Holding LLC, an investor which includes the Chairman of our Board of Directors, Richard S. Ressler, two of its executive officers, W. Brian Kretzmer and James W. Dolan, and its senior lender, Canyon Capital Advisors LLC (“Canyon”), which controls the majority of the Company’s common stock (84.2%) has acquired the Company’s $500,000 secured subordinated debt, plus interest, which was previously held by CSA, a majority owned subsidiary of Computer Sciences Corporation. In a separate action Canyon has agreed to restructure its $5.7 million 11% secured subordinated debt instrument with the Company. The previous terms of the Canyon debt required the Company to make monthly interest payments of $52,000 until the Wamco term loan is paid off in full in March 2006, at which time the note payable was to be converted into a three-year amortizing loan and requiring equal monthly payments of principal and interest of approximately $190,000.   Under terms of the amendment with Canyon, the terms of the debt have been modified to amortize the debt over a four and a half year period, such that monthly principal and interest payments will be reduced to approximately $130,000.  The loan will mature at the end of three years period at which time all remaining principal and interest shall be due and payable.

W. Brian Kretzmer, CEO of MAI Systems Corporation, commented, “These transactions are additional positive steps for our Company in improving its balance sheet and liquidity. The purchase of the CSA debt by HIS Holding LLC puts substantially all of the Company’s debt in control of its majority shareholders providing the Company a simple, flexible and more understandable capital structure. The restructuring of the Canyon debt also provides the company with a reasonable and balanced debt repayment schedule that allows us more flexibility to invest in our products and services. We are pleased with the cooperation of the parties involved and are confident that these transactions will assist the Company in improving its position in the marketplace.”
