ACE*COMM Reports Receipt of NASDAQ Capital Market Notification of Non-Compliance with Listing Standard.

GAITHERSBURG, Md. -- ACE*COMM Corporation (NASDAQ: ACEC), a global provider of value-added services and advanced operations support systems (OSS) solutions, today reported that NASDAQ has notified the company it is not in compliance with a continuous listing requirement for inclusion on the NASDAQ Capital Market. Cited was NASDAQ Marketplace Rule 4310(c)(3), which requires the Company to have a minimum of $2,500,000 in stockholders' equity or $35,000,000 market value of listed securities or $500,000 of net income from continuing operations for the most recently completed fiscal year or for two of the three most recently completed fiscal years.

Consequently, NASDAQ is reviewing the Company's eligibility for continuous listing on the Nasdaq Capital Market. To facilitate this review, the Company intends to provide, on or before, June 7, 2007, its specific plan to achieve and sustain compliance with all the Nasdaq Capital Market listing requirements, including the time frame for completing that plan. If, after the conclusion of the review process, Nasdaq determines that the company's plan does not adequately address the issues noted, the company will be provided with written notification that its securities will be delisted. At that time, the Company may appeal the decision to the Nasdaq Listing Qualifications Panel. The appeal process will suspend delisting until a determination is made by the Panel.
