     On June 3, 2009, Spire Corporation (the "Company") entered into a
Liquidation Agreement, as amended (the "Liquidation Agreement"), with Gloria
Solar Co., Ltd. and related entities ("Gloria Solar") pursuant to which the
parties agreed to liquidate their joint venture, Gloria Spire Solar, LLC (the

pursuing the solar photovoltaic systems market within the United States. The
Company owns 45% of the Joint Venture and Gloria Solar owns 55%.

     Under the terms of the Liquidation Agreement, the parties agreed to a
specified allocation of the remaining assets of the Joint Venture after all

responsibility over supporting the Joint Venture's existing client base,
including the remaining warranties.

     The liquidation of the Joint Venture is expected to be completed within 30
days.

     Under the terms of the Liquidation Agreement, as of the effective date of
the Joint Venture's dissolution, the primary Joint Venture-related agreements
will be terminated, including the Operating Agreement of the Joint Venture and
the original Contribution Agreement. All non-competition and non-solicitation
agreements between the parties contained in any of the Joint Venture-related
agreements will terminate as of the Dissolution Date.
