         MVSI AUTHORIZES STOCK REPURCHASE OF UP TO AN ADDITIONAL 1,000,000
                         SHARES OF MVSI COMMON STOCK

    MVSI, Inc. (Nasdaq: "MVSI"), a Washington, D.C. area broad-based
technology products and services company, announced today that the Company's
Board of Directors has authorized the Company to make additional open market
stock repurchases of up to 1,000,000 shares of MVSI Common Stock, $.01 par
value.  MVSI says it plans to buy shares on the open market or block
purchases from time to time, depending on market conditions.  Since January
1997, the Company and members of the Board of Directors have repurchased
approximately 2,000,000 shares, or about 12% of MVSI's outstanding Common
Stock, under earlier Board authorizations. This latest repurchase program
reflects the Board of Directors continued confidence in the Company's
fundamental strength and long-term growth prospects.
	
    MVSI Chairman Edward Ratkovich stated:  "We believe the securities of
MVSI are currently undervalued based on the Company's record revenue and
profit performance in the last quarter and our prediction of significantly
higher revenues and profits from all sources for the current and foreseeable
quarters."

    Chairman Ratkovich concluded: "Our progress to date in building our
software development and information technology (IT) business is going very
well.  We continue to aggressively address Year 2000 (Y2K) assessment,
remediation, testing and verification work; SAP and PeopleSoft
implementation; Internet, Intranet and Extranet development; technology
training; and custom-built management information systems for corporations
and government, directly with our clients or in partnership with other major
information technology companies, such as multi-billion dollar Science
Applications International Corporation (SAIC) of San Diego, California.
These business areas and significant partnerships continue to show the
greatest potential for growth and profitability for the Company."
