SPIRE CORPORATION NEWS RELEASE
FOR IMMEDIATE RELEASE

         SPIRE CORPORATION RECEIVES NOTICE OF NON-COMPLIANCE FROM NASDAQ

BEDFORD, MA - (BUSINESS WIRE) - March 6, 2009 - On March 3, 2009, Spire
Corporation (the "Company") received a Staff Determination Letter from The
Nasdaq Stock Market ("Nasdaq") indicating that the Company has not regained
compliance with Nasdaq Marketplace Rule 4450(b)(1)(A) as the market value of the
Company's common stock has remained below the minimum $50,000,000 required for
continued inclusion on The Nasdaq Global Market. Accordingly, its common stock
is subject to delisting from the Nasdaq Global Market.

The Company has requested a hearing before a Nasdaq Listing Qualifications Panel
to review the Staff Determination. The request for a hearing will stay the Staff
Determination and, as a result, the Company's common stock will remain listed on
The Nasdaq Global Market until the Panel issues its decision after the hearing.
There can be no assurance the Panel will grant the Company's request for
continued listing.

The Company expects to regain compliance with alternative continued listing
requirements upon the filing of its Annual Report on Form 10-K for 2008, whereby
the Company believes it will meet both (i) Marketplace Rule 4450(b)(1)(B), which
alternatively requires total assets and total revenue of at least $50,000,000
each for the most recently completed fiscal year or two of the three most
recently completed fiscal years and (ii) Marketplace Rule 4450(a)(3), which
alternatively requires stockholders' equity of at least $10 million.
