Statement of Financial Accounting Standards (SFAS) No. 142, Goodwill and Other
Intangible Assets. The Company has adopted SFAS 142 as of January 1, 2002. SFAS
142 requires goodwill and intangible assets with indefinite lives to no longer
be amortized, but instead be tested for impairment at least annually. With the
adoption of SFAS 142, the Company reassessed the useful lives and residual
values of all acquired intangible assets to make any necessary amortization
period adjustments. Based on that assessment, no adjustments were made to the
amortization period or residual values of other intangible assets.

     Other intangible assets amounted to $337,424 (net of accumulated
amortization of $495,165) and $234,813 (net of accumulated amortization of
$490,867) at June 30, 2002 and December 31, 2001, respectively. These intangible
assets primarily consist of patents that the Company had been awarded and are
amortized over their useful lives or their terms, principally five years. There
are no expected residual values related to these intangible assets. Amortization
expense for the six months ended June 30, 2002 was $6,965. Estimated fiscal year
amortization expense is as follows:

                    Amortization
       Year            Expense
     --------       ------------
       2002            $ 8,390
       2003             51,902
       2004             51,731
       2005             47,838
       2006             45,421

     The increase in sales of goods for the three month period ended June 30,
2002 is primarily due to increased demand for PV systems. The increase in the
contract research, service and license revenues are a result of an increased
demand for the Company's processing services.

     Net sales and revenues increased $1,704,000 or 28% for the six months ended
June 30, 2002 to $7,888,000, compared to $6,184,000 for the six months ended
June 30, 2001. Contract research, service and license revenues increased

     The increase in sales of goods for the six month period ended June 30, 2002
is primarily due to increased demand for PV systems. The increase in contract
research, service and license revenues for the six month period ended June 30,
2002 is attributed to the increase in contract research, service and license
revenues and an increase in the demand in the Company's biomedical processing
services as well as a growth in United States government research and
development contracts.

$25,000 to $1,022,000, decreasing to 59% of related revenues for the three
months ended June 30, 2002, compared to $1,047,000 or 82% of related revenues
for the three months ended June 30, 2001. The increase is due to a change in
product mix. Cost of goods sold increased $804,000 to $2,205,000, but decreased
to 78% of related sales, for the three months ended June 30, 2002, compared to

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

     Selling, general and administrative expenses for the three months ended
June 30, 2002 decreased $10,000 to $1,343,000, and decreased to 29% of sales and
revenues, compared to $1,353,000 or 46% of sales and revenues for the three
months ended June 30, 2001. The decrease in selling, general and administrative
expenses and decrease as a percentage of sales and revenues are due to the
continued cost containment efforts implemented by the Company.

     Selling, general and administrative expenses for the six months ended June
30, 2002 decreased $108,000 to $2,640,000, and decreased to 33% of sales and
revenues, compared to $2,748,000 or 44% of sales and revenues for the six months
ended June 30, 2001.

INTEREST

     The Company earned $20,000 of interest income for the quarter ended June
30, 2002, compared to $80,000 of interest income for the quarter ended June 30,
2001. The Company incurred interest expense of $10,000 for the quarter ended
June 30, 2002 of which zero was capitalized, compared to $20,000 in the second
quarter of 2001 of which $2,000 was capitalized. The decline of interest income
is due to the Company's utilization of available cash to fund operations.

INCOME TAXES

     The Company recorded no tax benefit for the quarter ended June 30, 2002,
compared to a tax benefit of $80,000 for the quarter ended June 30, 2001. The
Company recorded no tax benefit for the six months ended June 30, 2002, compared
to a tax benefit of $80,000 for the six months ended June 30, 2001.

NET EARNINGS (LOSS)

     The Company reported net earnings for the quarter ended June 30, 2002 of
$1,000, compared to a net loss of $697,000 for the quarter ended June 30, 2001.
The Company reported a net loss of $603,000 for the six months ended June 30,
2002, compared to a net loss of $1,301,000 for the same period of 2001. The loss
for the six months is attributed to manufacturing cycles in its photovoltaic
equipment business, as well as the Company's investment in a new product. The
Company began selling a hemodialysis catheter through a distributor network.

Liquidity and Capital Resources.
- -------------------------------

     To date the Company has been able to fund its operating cash requirements
by using proceeds from sale of assets, operations and available lines of credit.
On July 25, 2000, the Company entered into a new revolving credit agreement with
the Silicon Valley Bank. The Agreement was amended in January 2002 due to the
Company's violation of certain financial covenants, and the line of credit was
extended until April 2002. The Company has negotiated an amendment to extend the
agreement until April 23, 2003. The agreement provides for a $2 million
revolving credit facility, based upon eligible accounts receivable requirements.
The line of credit provides the Company with resources for general working
capital purposes and Standby Letter of Credit Guarantees for foreign customers.
The line is secured by all assets of the Company. At June 30, 2002, interest on
the line was at the Bank's prime rate plus 1/2 percent. The line contains
covenants including provisions relating to profitability and liquidity.
Borrowings on the line are classified as a current liability. As of June 30,
2002, the Company had no outstanding debt under this revolving credit facility.
Spire opened a Certificate of Deposit in the amount of $29,865 to protect the
outstanding Standby Letter of Credit Guarantee with a foreign customer.

     The Company believes it has sufficient resources to finance its current
operations for at least the next twelve months through working capital, its
existing line of credit and available lease arrangements. Cash and cash
equivalents decreased

                                       10


$1,142,000 to $4,441,000 at June 30, 2002 from $5,583,000 at December 31, 2001.
To date, there are no material commitments by the Company for capital
expenditures. At June 30, 2002, the Company's retained deficit was $379,000,
compared to retained earnings of $225,000 as of December 31, 2001. Working
capital as of June 30, 2002 decreased 4% to $6,487,000, from $6,759,000 as of
December 31, 2001.

Recent Accounting Pronouncements.
- --------------------------------

     In July 2001, the FASB issued SFAS No. 142, Goodwill and Other Intangible
Assets. The Company has adopted SFAS 142 as of January 1, 2002. SFAS 142
requires goodwill and intangible assets with indefinite lives to no longer be
amortized, but instead be tested for impairment at least annually. With the
adoption of SFAS 142, the Company reassessed the useful lives and residual
values of all acquired intangible assets to make any necessary amortization
period adjustments. Based on that assessment, no adjustments were made to the
amortization period or residual values of other intangible assets.

     SFAS No. 143, "Accounting For Asset Retirement Obligations," issued in
August 2001, addresses financial accounting and reporting for obligations
associated with the retirement of tangible long-lived assets and for the
associated retirement costs. SFAS 143 which applies to all entities that have a
legal obligation associated with the retirement of a tangible long-lived asset
is effective for fiscal years beginning after June 15, 2001. The Company does
not expect the implementation of SFAS 143 to have a material impact on its
financial condition or results of operations.

     SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived
Assets," issued in October 2001, addresses financial accounting and reporting
for the impairment or disposal of long-lived assets. SFAS 144, which applies to
all entities, is effective for fiscal years beginning after December 15, 2001.
The Company's adoption of SFAS 144 did not have a material impact on its
financial condition or results of operations.

     In April 2002 the FASB issued SFAS No. 145, "Rescission of FASB Statement
Nos. 4, 44, and 64, Amendment of FASB Statement No. 13 and Technical
Corrections," effective for fiscal years beginning May 15, 2002 or later. It
rescinds SFAS No. 4, "Reporting Gains and Losses From Extinguishments of Debt,"
SFAS No. 64, "Extinguishments of Debt to Satisfy Sinking-Fund Requirements," and
SFAS No. 44, "Accounting for Intangible Assets of Motor Carriers." This
Statement also amends SFAS No. 13, "Accounting for Leases to eliminate an
inconsistency between the required accounting for sale-leaseback transactions
and the required accounting for certain lease modifications that have economic
effects that are similar to sale-leaseback transactions. This Statement also
amends other existing authoritative pronouncements to make various technical
corrections, clarify meanings or describe their applicability under changed
conditions. We do not believe the impact of adopting SFAS No. 145 will have a
material impact on our financial statements.

     In June 2002 the FASB issued SFAS No. 146, "Accounting for Costs Associated
with Exit or Disposal Activities.". SFAS No. 146 requires companies to recognize
costs associated with exit or disposal activities when they are incurred rather
than at the date of commitment to an exit or disposal plan. This statement is
effective for exit or disposal activities initiated after December 31, 2002. We
do not believe the impact of adopting SFAS No. 145 will have a material impact
on our financial statements.

Impact of Inflation and Changing Prices.
- ---------------------------------------

     Historically, the Company's business has not been materially impacted by
inflation. Manufacturing equipment sales and solar systems are generally quoted,
manufactured and shipped within a cycle of approximately six months, allowing
for orderly pricing adjustments to the cost of labor and purchased parts. The
Company has not experienced any negative effects from the impact of inflation on
long-term contracts. The Company's service business is not expected to be
seriously affected by inflation because its procurement-production cycle
typically ranges from two weeks to several months, and prices generally are not
fixed for more than one year. Research and development contracts usually include
cost escalation provisions.

Foreign Exchange Fluctuation.
- ----------------------------

     The Company sells only in U.S. dollars, generally against an irrevocable
confirmed letter of credit through a major United States bank. Therefore the
Company is not directly affected by foreign exchange fluctuations on its current
orders. However, fluctuations in foreign exchange rates do have an effect on the
Company's customers' access to U.S. dollars and on the pricing competition on
certain pieces of equipment that the Company sells in selected markets.

Related Party Transactions.
- --------------------------

     The Company subleases 74,000 square feet in a building from Mykrolis
Corporation, which leases the building from a Trust of which Roger G. Little,
Chief Executive Officer, is sole trustee and principal beneficiary. The Company
believes that the terms of the sublease are commercially reasonable. The 1985
sublease originally was for a period of ten years, was extended for a five-year
period expiring on November 30, 2000 and was further extended for a five-year
period expiring on November 30, 2005. The agreement provides for minimum rental
payments plus annual increases linked to the consumer price index. Total rent
expense under this sublease was $999,000 in 2001. This amount does not take into
account rent received by the Company for subleasing approximately 22,000 square
feet of its 74,000 square feet to the purchaser of the Company's optoelectronics
business.

Critical Accounting Policy - Revenue Recognition.
- ------------------------------------------------

     The Company derives its revenues from three primary sources: (1) sales of
solar energy manufacturing equipment and solar energy systems; (2) biomedical
processing services; and (3) U.S. government funded research and development
contracts.

     The Company's OEM capital equipment solar energy business builds complex
customized machines to order for specific customers. Substantially all of these
orders are sold on a FOB Bedford, Massachusetts basis. It is the Company's
policy to recognize revenues for this equipment as the product is shipped to the
customer as customer acceptance is obtained prior to shipment and the equipment
is expected to operate the same in the customer's environment as it does in the
Company's. When an arrangement with the customer includes future obligations or
customer acceptance, revenue is recognized when those obligations are met or
customer acceptance has been achieved. The Company's solar energy systems
business installs solar energy systems on customer owned properties on a
contractual basis. Generally, revenue is recognized once the systems have been
installed and the title is passed to the customer. For arrangements with a
number of elements, the Company allocates fair value to each element based on
rates quoted in the contract and revenue is recognized upon delivery of the
element. The Company's biomedical subsidiary performs surface engineering
services to various medical device manufacturers on a contractual basis. The
Company recognizes revenue as the products are shipped back to the customer. The
Company recognizes revenues and estimated profits on long term government
contracts on a percentage of completion method of accounting using a cost to
cost methodology. Profit estimates are revised periodically based upon changes
and facts, and any losses on contracts are recognized immediately. Some of the
contracts include provisions to withhold a portion of the contract value as
retainage until such time as the U.S. Government performs an audit of the cost
incurred under the contract. The Company's policy is to take into revenue the
full value of the contract, including any retainage, as it performs against the
contract since the Company has not experienced any substantial losses as a
result of an audit performed by the Government.

Contractual Obligations and Commercial Commitments.

     On October 8, 1999, the Company entered into an Agreement with BP Solarex
("BPS") in which BPS agreed to purchase certain production equipment built by
the Company, for use in the Company's Chicago factory and in return the Company
agreed to purchase solar cells of a minimum of 2 megawatts per year over a
five-year term. BPS has the right to repossess the equipment should the Company
not purchase its committed quantity. The proceeds from the sale of the
production equipment purchased by BPS have been classified as an unearned
purchase discount in the accompanying balance sheet. The Company will amortize
this discount as a reduction to cost of sales as it purchases solar cells from
BPS which amounted to zero during the quarter ended June 30, 2002.
