CHERRY HILL, NJ -- (June 1, 2001) -- Science Dynamics ³SciDyn² (NASDAQ SC: SIDY), a developer of Internet Protocol-based (IP) telephony solutions and services, today announced that the NASDAQ SmallCap Market has informed the Company that its common stock will be subject to delisting. SciDyn needs to be in compliance with one of the following minimum requirements, net tangible assets or market capitalization or net income for continued listing, as set forth in NASDAQ's Marketplace Rules.

As permitted by NASDAQ, the Company will provide the NASDAQ Staff with a plan by June 15th, 2001, outlining how it intends to comply with listing requirements. If after the NASDAQ Staff review it is determined that the plan does not adequately address the issues noted, written notification of delisting will be provided. At that time, the Company may appeal the Staff¹s decision to a NASDAQ Listing Qualifications Panel. There can be no assurances the Panel will grant the Company's request for continued listing. The Company's stock will continue to be listed on NASDAQ SmallCap Market pending a final decision. In the event Science Dynamics is delisted following the NASDAQ hearing, the stock would likely trade on the OTC Bulletin Board.
