ITEM 2.02    RESULTS OF OPERATIONS AND FINANCIAL CONDITION.

ITEM 3.01    NOTICE OF DELISTING OR FAILURE TO SATISFY A CONTINUED LISTING RULE
             OR STANDARD; TRANSFER OF LISTING.

     As previously disclosed, on April 27, 2005, Spire Corporation (the
"Company") received a Determination Letter from the Nasdaq Staff indicating that
the Company was no longer in compliance with the $10,000,000 minimum
stockholders' equity requirement for continued listing set forth in Nasdaq
Marketplace Rule 4450(a)(3)(the "Rule"). The Nasdaq Staff requested that the
Company provide a plan to achieve and sustain compliance with Nasdaq listing
standards. On May 12, 2005, the Company presented such a plan to the Nasdaq
Staff. On May 24, 2005, the Nasdaq Staff requested additional information from
the Company regarding certain projected nonrecurring license sales that were
expected to occur during the second quarter of 2005. On June 3, 2005, the
Company submitted a revised plan to achieve compliance with the Rule
incorporating the subject license sales. On June 6, 2005, the Company received a
letter from the Nasdaq Staff stating that the Company provided a definitive plan
evidencing its ability to achieve and sustain compliance with the Rule, and as
such, granted the Company an extension of time to achieve compliance. The terms
of the extension require the Company to file a Form 8-K on or before August 5,
2005 including:

     1.   A disclosure of Nasdaq Staff's deficiency letter and specific
          deficiencies cited;

     2.   A description of the completed transaction or event that enabled the
          Company to satisfy the stockholders' equity requirement for continued
          listing;

     3.   An affirmative statement that, as of the date of the report, the
          Company believes it has regained compliance with the stockholders'
          equity requirement based upon the specific transaction or event
          referenced in Step 2; and

     4.   A disclosure stating that the Nasdaq will continue to monitor the
          Company's ongoing compliance with the stockholders' equity requirement
          and, if at the time of its next periodic report the Company does not
          evidence compliance, that it may be subject to delisting.

     The Company completed the following transactions during the second quarter
ended June 30, 2005:

     1.   On June 16, 2005, the Company received its final $3,000,000 payment
          from the October 2002 sale of its exclusive hemodialysis split-tip
          catheter license to Bard Access Systems. This payment has been
          recorded as a $3 million gain on sale of a license.

     2.   On June 27, 2005, the Company received JPY 400,000,000 (approximately
          $3.6 million) from the sale of a license to its solar technology to a
          Japanese partner. The Company expects to record a gain from the sale
          of this license during the quarter ended June 30, 2005.

     As a result of the above noted transactions, the Company believes that it
has regained compliance with the Rule as of June 30, 2005.

     Nasdaq will continue to monitor the Company's ongoing compliance with the
Rule. If the Company fails to evidence compliance with the Rule upon filing its
next periodic report with the SEC, the Company may be subject to delisting. If
the Company were to receive a written notification of delisting from Nasdaq, it
could appeal the decision to a Nasdaq Listing Qualifications Panel. If such an
appeal were unsuccessful, the Company could apply to list the Company's common
stock on the Nasdaq SmallCap Market.

     Although the Company believes it has regained compliance with the Rule as
of June 30, 2005, in order to avoid future listing problems with respect to the
Nasdaq National Market, the Company may still decide to apply to transfer the
listing of its common stock to the Nasdaq SmallCap Market.
