                       SPIRE CORPORATION AND SUBSIDIARIES
         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                             JUNE 30, 2008 AND 2007


1.     DESCRIPTION OF THE BUSINESS

       Spire Corporation ("Spire" or the "Company") is a Massachusetts
corporation incorporated in 1969. The Company's principal offices are located at
One Patriots Park, Bedford, Massachusetts, and its phone number is (781)
275-6000. The Company's SEC filings are available through its website,
www.spirecorp.com. The Company's common stock trades on the Nasdaq Global Market
under the symbol "SPIR".

       The Company principally develops, manufactures and markets customized
turnkey solutions for the solar industry, including manufacturing equipment and
full turnkey lines for cell and module production and testing. The Company also
offers through its subsidiary Spire Semiconductor concentrator cell and
light-emitting diode ("LED") fabrication services and through its joint venture,
Gloria Spire Solar, photovoltaic ("PV") system integration services. The Company
also operates a line of business associated with advanced biomedical
applications. The foundation for the Company's business is its industry-leading
expertise in materials technologies and surface treatments; this proprietary
knowledge enables the Company to further develop its offerings in solar
equipment, optoelectronics and biomedical products and services.

       In the PV solar area, the Company develops, manufactures and markets
specialized equipment for the production of terrestrial photovoltaic modules
from solar cells. The Company's equipment has been installed in approximately
190 factories in 50 countries.

       In addition to the Company's cell and module manufacturing solutions, it
has a device fabrication facility where it produces, under contract with its
customers, gallium arsenide (GaAs) concentrator cells. Under the name Spire
Semiconductor, this division produces GaAs concentrator cells, high performance
LEDs, and other custom semiconductor foundry services for the Company's
customers.

       In the biomedical area, the Company provides value-added surface
treatments to manufacturers of orthopedic and other medical devices that enhance
the durability, antimicrobial characteristics or other material characteristics
of their products; develops and markets coated and uncoated hemodialysis
catheters and related devices for the treatment of chronic kidney disease; and
performs sponsored research programs into practical applications of advanced
biomedical and biophotonic technologies.

       In July 2007, the Company entered into a joint venture with Gloria Solar
Co., Ltd., a leading module manufacturer in Taiwan, which designs, sells and
manages installations of photovoltaic systems. The Company's 45% ownership stake
in the joint venture, Gloria Spire Solar, LLC, was obtained through the
contribution of its integrated photovoltaic business to Gloria Solar. This
transaction has allowed the Company to focus more of its attention on its core
solar business, while continuing to expand the Spire brand name in the
marketplace.

       The Company has been in the solar business for over 30 years and has been
active in research and development in the space, with over $100 million of
research and development conducted which has led to over 60 patents granted to
date, as well as cell and module production, having been a pioneer in the early
development of solar technology. This expertise has provided the platform and
expertise for the Company's manufacturing equipment.

       Operating results will depend upon revenue growth and product mix, as
well as the timing of shipments of higher priced products from the Company's
solar equipment line. Export sales, which amounted to 61% of net sales and
revenues for the quarter ended June 30, 2008, continue to constitute a
significant portion of the Company's net sales and revenues.

       The Company has incurred significant operating losses in 2007 and 2006.
Loss from operations, before gain on sales of trademarks, were $6.4 million and
$8.3 million in 2007 and 2006, respectively. Income from operations for the six
months ended June 30, 2008 was $103,000. Previous losses from operations have
resulted in cash losses (loss from operations excluding gain on sales of
trademark plus or minus non-cash adjustments) of approximately $5.9 million and
$5.4 million in 2007 and 2006, respectively. The Company has funded these cash
losses from cash receipts of $4.0 million from the sale of a solar PV module
line along with the transfer of technology and rights to mark the modules with
the Company's trademark to the joint venture in 2007 and $7.7 million from the
sale of equity in 2006. For the six months ended June 30, 2008, the cash gain
(income from operations plus or minus non-cash adjustments) was $1,886,000. As
of June 30, 2008, the Company had unrestricted cash and cash equivalents of $4.5
million compared to unrestricted cash and

                                        4

cash equivalents of $2.4 million as of December 31, 2007. While the Company has
had positive cash flow from operations for the past three quarters, the Company
continues to experience net losses. While the Company has numerous options on
how to fund these losses, including but not limited to sales of equity or the
sale or license of assets and technology, just as it has done the past; however,
there are no assurances that the Company would be able to sell equity or sell or
license those assets on a timely basis and at appropriate values. The Company
has developed several plans to mitigate cash losses primarily from increased
revenues and, if required, potential cost reduction efforts and outside
financing. As a result, the Company believes it has sufficient resources to
continue as a going concern through at least June 30, 2009.


2.     INTERIM FINANCIAL STATEMENTS

       The accompanying unaudited condensed consolidated financial statements
have been prepared in accordance with the rules and regulations of the
Securities and Exchange Commission regarding interim financial reporting.
Certain information and footnote disclosures normally included in consolidated
financial statements prepared in accordance with accounting principles generally
accepted in the United States of America have been condensed or omitted in
accordance with such rules and regulations. These unaudited condensed
consolidated financial statements should be read in conjunction with the annual
audited consolidated financial statements and notes thereto for the year ended
December 31, 2007, included in the Company's Annual Report on Form 10-K filed
with the Securities and Exchange Commission.

       In the opinion of management, the accompanying unaudited, condensed
consolidated financial statements contain all adjustments necessary to fairly
present the Company's financial position as of June 30, 2008 and December 31,
2007 and the results of its operations and cash flows for the three and six
months ended June 30, 2008 and 2007. The results of operations for the three and
six months ended June 30, 2008 are not necessarily indicative of the results to
be expected for the fiscal year ending December 31, 2008. The condensed
consolidated balance sheet as of December 31, 2007 has been derived from audited
financial statements as of that date.

       The accounting policies followed by the Company are set forth in Footnote
2 to the Company's consolidated financial statements in its Annual Report on
Form 10-K for the year ended December 31, 2007.

New Accounting Pronouncements
-----------------------------

       In December 2007, the Financial Accounting Standards Board ("FASB")
issued Statement of Financial Accounting Standards ("SFAS") No. 141R ("FAS
141R"), BUSINESS COMBINATIONS, which revises FAS 141 and changes multiple
aspects of the accounting for business combinations. Under the guidance in FAS
141R, the acquisition method must be used, which requires the acquirer to
recognize most identifiable assets acquired, liabilities assumed, and
non-controlling interests in the acquiree at their full fair value on the
acquisition date. Goodwill is to be recognized as the excess of the
consideration transferred plus the fair value of the non-controlling interest
over the fair values of the identifiable net assets acquired. Subsequent changes
in the fair value of contingent consideration classified as a liability are to
be recognized in earnings, while contingent consideration classified as equity
is not to be re-measured. Costs such as transaction costs are to be excluded
from acquisition accounting, generally leading to recognizing expense, and,
additionally, restructuring costs that do not meet certain criteria at
acquisition date are to be subsequently recognized as post-acquisition costs.
FAS 141R is effective for business combinations for which the acquisition date
is on or after the beginning of the first annual reporting period beginning on
or after December 15, 2008. The Company is currently evaluating the impact, if
any, that this standard will have on its financial position and results of
operations.

       In December 2007, the FASB issued SFAS No. 160 ("FAS 160"),
NON-CONTROLLING INTEREST IN CONSOLIDATED FINANCIAL STATEMENTS - AN AMENDMENT OF
ARB NO. 151. FAS 160 requires that a non-controlling interest in a subsidiary
(i.e. minority interest) be reported in the equity section of the balance sheet
instead of being reported as a liability or in the mezzanine section between
debt and equity. It also requires that the consolidated income statement include
consolidated net income attributable to both the parent and non-controlling
interest of a consolidated subsidiary. A disclosure must be made on the face of
the consolidated income statement of the net income attributable to the parent
and to the non-controlling interest. Also, regardless of whether the parent
purchases additional ownership interest, sells a portion of its ownership
interest in a subsidiary or the subsidiary participates in a transaction that
changes the parent's ownership interest, as long as the parent retains
controlling interest, the transaction is considered an equity transaction. FAS
160 is effective for annual periods beginning after December 15, 2008. The
Company is currently evaluating the impact, if any, that this standard will have
on its financial position and results of operations.

       In March 2008, the FASB issued SFAS No. 161 ("FAS 161"), DISCLOSURES
ABOUT DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES--AN AMENDMENT OF FASB
STATEMENT NO. 133. FAS 161 requires enhanced disclosures about an entity's
derivative and hedging activities. Entities are required to provide enhanced
disclosures about (a) how and why an entity uses

                                        5

derivative instruments, (b) how derivative instruments and related hedged items
are accounted for under Statement No. 133 and its related interpretations, and
(c) how derivative instruments and related hedged items affect an entity's
financial position, financial performance, and cash flows. FAS 161 is effective
for financial statements issued for fiscal years and interim periods beginning
after November 15, 2008, with early application encouraged. FAS 161 encourages,
but does not require, comparative disclosures for earlier periods at initial
adoption. The Company is currently evaluating the impact, if any, that this
standard will have on its financial position and results of operations.

       In May 2008, the FASB issued SFAS No. 162 ("FAS 162"), THE HIERARCHY OF
GENERALLY ACCEPTED ACCOUNTING Principles. FAS 162 identifies the sources of
accounting principles and the framework for selecting the principles to be used
in the preparation of financial statements that are presented in conformity with
generally accepted accounting principles in the United States. FAS 162 is
effective 60 days following the SEC's approval of the Public Company Accounting
Oversight Board amendments to AU Section 411, THE MEANING OF PRESENT FAIRLY IN
CONFORMITY WITH GENERALLY ACCEPTED ACCOUNTING PRINCIPLES. The Company is
currently evaluating the impact, if any, that this standard will have on its
financial position and results of operations.

       In May 2008, the FASB issued SFAS No. 163, ("FAS 163") ACCOUNTING FOR
FINANCIAL GUARANTEE INSURANCE CONTRACTS - AN INTERPRETATION OF FASB STATEMENT
NO. 60. FAS 163 requires that an insurance enterprise recognize a claim
liability prior to an event of default when there is evidence that credit
deterioration has occurred in an insured financial obligation. It also clarifies
how Statement 60 applies to financial guarantee insurance contracts, including
the recognition and measurement to be used to account for premium revenue and
claim liabilities, and requires expanded disclosures about financial guarantee
insurance contracts. It is effective for financial statements issued for fiscal
years beginning after December 15, 2008, except for some disclosures about the
insurance enterprise's risk-management activities. FAS 163 requires that
disclosures about the risk-management activities of the insurance enterprise be
effective for the first period beginning after issuance. Except for those
disclosures, earlier application is not permitted. The Company is currently
evaluating the impact, if any, that this standard will have on its financial
position and results of operations.

       Retainage represents revenues on certain United States government
sponsored research and development contracts. These amounts, which usually
represent 15% of the Company's research fee on each applicable contract, are not
collectible until a final cost review has been performed by government auditors.
The government's most recent audit was as of December 31, 2006, with no adverse
impact.

       Accrued revenue represents revenues recognized on contracts for which
billings have not been presented to customers as of the balance sheet date.
These amounts are billed and generally collected within one year.

       The Company maintains allowances for doubtful accounts for estimated
losses resulting from the inability of its customers to pay amounts due. The
Company actively pursues collection of past due receivables as the circumstances
warrant. Customers are contacted to determine the status of payment and senior
accounting and operations management are included in these efforts as is deemed
necessary. A specific reserve will be established for past due accounts when it
is probable that a loss has been incurred and the Company can reasonably
estimate the amount of the loss. The Company does not record an allowance for
government receivables and invoices backed by letters of credit as
realizeability is reasonably assured. Bad debts are written off against the
allowance when identified. There is no dollar threshold for account balance
write-offs. While rare, a write-off is only recorded when all efforts to collect
the receivable have been exhausted and only in consultation with the appropriate
business line manager.

       In addition, the Company maintains an allowance for potential future
product returns and rebates related to current period revenues. The Company
analyzes the rate of historical returns when evaluating the adequacy of the
allowance for

                                        6

sales returns and allowances. Returns and rebates are charged against the
allowance when incurred.

       Advances on contracts in progress represent contracts for which billings
have been presented to the customer, either as deposits or progress payments
against future shipments, but revenue has not been recognized.

125,360 and 106,230 shares, respectively, of common stock related to stock
options were excluded from the calculation of dilutive shares because the
inclusion of such shares would be anti-dilutive due to the Company's net loss
position.

       In addition, for the three and six months ended June 30, 2008, 39,500 and
zero shares, respectively, and for the three and six months ended June 30, 2007,
6,250 and 91,250 shares, respectively, of common stock issuable relative to
stock options were excluded from the calculation of diluted shares because their
inclusion would have been anti-dilutive, due to their exercise prices exceeding
the average market price of the stock for the periods.

       Revenues from contracts with United States government agencies for the
six months ended June 30, 2008 and 2007 were approximately $753,000 and
$520,000, or 2% and 3% of consolidated net sales and revenues, respectively.

       One customer accounted for approximately 11% and two customers accounted
for approximately 37% of the Company's gross sales during the three months ended

7.     INTANGIBLE AND OTHER ASSETS

       Patents amounted to $117,000, net of accumulated amortization of
$713,000, at June 30, 2008. Licenses amounted to $83,000, net of accumulated
amortization of $242,000, at June 30, 2008. Patent cost is primarily composed of
cost associated with securing and registering patents that the Company has been
awarded or that have been submitted to, and the Company believes will be
approved by, the government. License cost is composed of the cost to acquire
rights to the underlying technology or know-how. These costs are capitalized and
amortized over their useful lives or terms, ordinarily five years, using the
straight-line method. There are no expected residual values related to these
patents or licenses. For disclosure purposes, the table below includes future
amortization expense for licenses and patents owned by the Company as well as
$640,000 of estimated amortization expense on a five-year straight-line basis
related to patents that remain pending as of the balance sheet date.

                                        8

       Estimated amortization expense for the periods ending December 31, is as

of unamortized expenses that were prepaid.


8.     AVAILABLE-FOR-SALE INVESTMENTS

       Available-for-sale securities consist of the following assets held as
part of the Spire Corporation Non-Qualified Deferred Compensation Plan:

                                             June 30, 2008    December 31, 2007

             Cash and money market funds          52,000            86,000
                                          -----------------   -----------------
                                              $1,637,000        $1,800,000
                                          =================   =================

       These investments have been classified as long-term available-for-sale
investments and are reported at fair value, with unrealized gains and losses
included in accumulated other comprehensive loss. As of June 30, 2008, the
unrealized loss on these marketable securities was $59,000.

       Effective January 1, 2008, the Company adopted SFAS No. 157, "Fair Value
Measurements" ("FAS 157"). In February 2008, the FASB issued FASB Staff Position
No. FAS 157-2, "Effective Date of FASB Statement No. 157," which provides a one
year deferral of the effective date of FAS 157 for non-financial assets and
non-financial liabilities, except those that are recognized or disclosed in the
financial statements at fair value at least annually. Therefore, the Company has
adopted the provisions of FAS 157 with respect to its financial assets and
liabilities only. FAS 157 defines fair value, establishes a framework for
measuring fair value, and expands disclosures about fair value measurements. The
new standard provides a consistent definition of fair value which focuses on an
exit price which is the price that would be received to sell an asset or paid to
transfer a liability in an orderly transaction between market participants at
the measurement date. The standard also prioritizes, within the measurement of
fair value, the use of market-based information over entity specific information
and establishes a three-level hierarchy for fair value measurements based on the
nature of inputs used in the valuation of an asset or liability as of the
measurement date.

       The hierarchy established under FAS 157 gives the highest priority to
unadjusted quoted prices in active markets for identical assets or liabilities
(Level 1) and the lowest priority to unobservable inputs (Level 3). As required
by FAS 157, the Company's available for sale investments are classified within
the fair value hierarchy based on the lowest level of input that is significant
to the fair value measurement. The three levels of the fair value hierarchy
under FAS 157, and its applicability to the Company's available for sale
investments, are described below:

       Level 1 - Pricing inputs are quoted prices available in active markets
       for identical investments as of the reporting date. As required by FAS
       157, the Company does not adjust the quoted price for these investments,
       even in situations where the Company holds a large position and a sale
       could reasonably impact the quoted price.

       Level 2 - Pricing inputs are quoted prices for similar investments, or
       inputs that are observable, either directly or indirectly, for
       substantially the full term through corroboration with observable market
       data. Level 2 includes investments valued at quoted prices adjusted for
       legal or contractual restrictions specific to these investments.

       Level 3 - Pricing inputs are unobservable for the investment, that is,
       inputs that reflect the reporting entity's own assumptions about the
       assumptions market participants would use in pricing the asset or
       liability. Level 3 includes investments that are supported by little or
       no market activity.

9.     NOTES PAYABLE AND CREDIT ARRANGEMENTS

       The Company had a $2,000,000 Loan Agreement with Citizens Bank of
 Massachusetts which expired on June 26, 2007. On May 25, 2007, the Company and
 its wholly-owned subsidiary, Spire Semiconductor, LLC, entered into a Loan and
Security Agreement (the "Equipment Credit Facility") with Silicon Valley Bank
(the "Bank"). Under the Equipment Credit Facility, for a one-year period, the
Company and Spire Semiconductor could borrow up to $3,500,000 in the aggregate
to finance certain equipment purchases (including reimbursement of certain
previously-made purchases). Advances made under the Equipment Credit Facility
would bear interest at the Bank's prime rate, as determined, plus 0.5% and
payable in thirty-six (36) consecutive monthly payments following the funding
date of that advance.

       On March 31, 2008, the Company entered into a second Loan and Security
Agreement (the "Revolving Credit Facility") with the Bank. Under the terms of
the Revolving Credit Facility, the Bank agreed to provide the Company with a
credit line up to $5,000,000. The Company's obligations under the Equipment
Credit Facility are secured by substantially all of its assets and advances
under the Revolving Credit Facility are limited to 80% of eligible receivables
and the lesser of 25% of the value of its eligible inventory, as defined, or
$2,500,000 if the inventory is backed by a customer letter of credit. Interest
on outstanding borrowings accrues at a rate per annum equal to the greater of
Prime Rate plus one percent (1.0%) or seven percent (7%). In addition, the
Company agreed to pay to the Bank a collateral monitoring fee of $750 per month
in the event the Company is in default of its covenants and agreed to the
following additional terms: (i) $50,000 commitment fee; (ii) an unused line fee
in the amount of 0.75% per annum of the average unused portion of the revolving
line; and (iii) an early termination fee of 0.5% of the total credit line if the
Company terminates the Revolving Credit Facility prior to 12 months from the
Revolving Credit Facility's effective date. The Revolving Credit Facility, if
not sooner terminated in accordance with its terms, expires on March 30, 2009.
In addition, on March 31, 2008 the Company's existing Equipment Credit Facility
was amended whereby the Bank granted a waiver for the Company's defaults for not
meeting its December 31, 2007 quarter liquidity and profit covenants and for not
meeting its January and February 2008 liquidity covenants. Further, the
covenants were amended to match the covenants as discussed below contained in
the Revolving Credit Facility. The Company's interest rate under the Equipment
Credit Facility was also modified from Bank Prime plus one half percent to the
greater of Bank Prime plus one percent (1%) or seven percent (7%).

       On May 13, 2008, the Bank amended the Equipment Credit Facility and the
Revolving Credit Facility, modifying the Company's net income profitability
covenant requirements in exchange for a three quarters percent (0.75%) increase
in the Company's interest rate (7.75% at June 30, 2008) and waiver restructuring
fee equal to one half percent (0.5%) of amounts outstanding under the Equipment
Credit Facility and committed under the Revolving Credit Facility. In addition,
the Company's term loan balance will be factored in when calculating the
Company's borrowing base under the Revolving Credit Facility.

       Under the amended terms of both credit facilities, as long as any
commitment remains outstanding under the facilities, the Company must comply
with an adjusted quick ratio covenant and a minimum monthly net income covenant.
In addition, until all amounts under the credit facilities with the Bank are
repaid, covenants under the credit facilities impose restrictions on the
Company's ability to, among other things, incur additional indebtedness, create
or permit liens on the Company's assets, merge, consolidate or dispose of assets
(other than in the ordinary course of business), make dividend and other
restricted payments, make certain debt or equity investments, make certain
acquisitions, engage in certain transactions with affiliates or change the
business conducted by the Company and its subsidiaries. Any failure by the
Company to comply with the covenants and obligations under the credit facilities
could result in an event of default, in which case the Bank may be entitled to
declare all amounts owed to be due and payable immediately. The Company's
obligations under the credit facilities are secured by substantially all of its
assets.

       At June 30, 2008, the Company's outstanding borrowings from the Equipment
Credit Facility amounted to $2,333,000 and there were no borrowings from the
Revolving Credit Facility. The Company was in compliance with its covenants as
of June 30, 2008.

10.    STOCK OPTION PLAN AND STOCK-BASED COMPENSATION

       On January 1, 2006, the Company adopted the fair value recognition
provisions of FASB Statement No. 123(R), Share-Based Payment ("Statement
123(R)") using the modified prospective method. Based on an analysis of the
Company's historical data, for the three months ended June 30, 2008 and 2007,
the Company applied 8% and 14% forfeiture rates, respectively, to stock options
outstanding in determining its Statement 123(R) stock-based compensation expense
which it believes are reasonable forfeiture estimates for the periods. The
impact of Statement 123(R) on the Company's results of operations resulted in
recognition of stock-based compensation expense of approximately $213,000 and
$137,000 for the three months ended June 30, 2008 and 2007, respectively, and
approximately $409,000 and $208,000 for the six months ended June 30, 2008 and
2007, respectively. The total non-cash, stock-based compensation expense
included in the condensed consolidated statement of operations for the periods
presented is included in the following expense categories:

                                                      Three Months Ended June 30,        Six Months Ended June 30,

       At June 30, 2008 the Company had outstanding options under two stock
option plans: the 1996 Equity Incentive Plan (the "1996 Plan") and the 2007
Stock Equity Plan (the "2007 Plan"). Both plans were approved by stockholders
and provided that the Board of Directors may grant options to purchase the
Company's common stock to key employees and directors of the Company. Incentive
and non-qualified options must be granted at least at the fair market value of
the common stock or, in the case of certain optionees, at 110% of such fair
market value at the time of grant. The options may be exercised, subject to
certain vesting requirements, for periods up to ten years from the date of
issue. The 1996 Plan expired with respect to the issuance of new grants as of
December 10, 2006. Accordingly, future grants may be made only under the 2007
Plan.

       A summary of options outstanding under the 2007 Plan and 1996 Plan as of
June 30, 2008 and changes during the six-month period is as follows:

       The per-share weighted-average fair value of stock options granted during
the three and six months ended June 30, 2008 was $9.15 and $7.96, respectively,
and $6.45 for both periods in 2007, on the date of grant using the Black-Scholes
option-pricing model with the following weighted-average assumptions:

                    Expected        Risk-Free      Expected        Expected
         Year    Dividend Yield   Interest Rate   Option Life  Volatility Factor

       The risk free interest rate reflects treasury yields rates over a term
that approximates the expected option life. The expected option life is
calculated based on historical lives of all options issued under the plan. The
expected volatility factor is determined by measuring the actual stock price
volatility over a term equal to the expected useful life of the options granted.

CONDITION AND RESULTS OF OPERATIONS SHOULD BE READ IN LIGHT OF THOSE FACTORS AND
IN CONJUNCTION WITH OUR ACCOMPANYING CONSOLIDATED FINANCIAL STATEMENTS,
INCLUDING THE NOTES THERETO.

OVERVIEW

       We principally develop, manufacture and market customized turnkey
solutions for the solar industry, including manufacturing equipment and full
turnkey lines for cell and module production and testing. We also offer through
our subsidiary Spire Semiconductor concentrator cell and light-emitting diode
("LED") fabrication services and through our joint venture Gloria Spire Solar
photovoltaic ("PV") system integration services. We also operate a line of
business associated with advanced biomedical applications. The foundation for
our business is our industry-leading expertise in materials technologies and
surface treatments; this proprietary knowledge enables us to further develop our
offerings in solar equipment, optoelectronics and biomedical products and
services.

       Our initial focus on high-energy physics led to the development of our
first product, the SPI-PULSE electron beam generator, to support research in
radiation effects testing. We moved into the space solar cell business after
signing a contract to develop solar cell coverslip for radiation hardening. In
addition, we began to develop a new technology based on ion implantation and
pulsed electron beam annealing of silicon solar cells. As a result of the energy
crisis in the early 1980s, which forced the United States to consider
photovoltaics for terrestrial applications, we received our first terrestrial
solar cell contract for low cost production using our ion implantation
technology. We leveraged this knowledge to develop our state-of-the-art
manufacturing equipment, in addition to our offerings in the optoelectronics and
biomaterials industries.

       As photovoltaic cell and module manufacturers ramp up production to meet
increasing demand, they will first need to acquire greater quantities of turnkey
equipment in order to produce more photovoltaic cells and modules. We believe
that we are one of the world's leading suppliers of the manufacturing equipment
and technology needed to produce solar photovoltaic power systems. Our
individual manufacturing equipment products and our SPI-LINETM integrated
turnkey cell and module production lines can be highly scaled, customized, and
automated with high throughput. These systems are designed to meet the needs of
a broad range of customers ranging from manufacturers relying on mostly manual
processes, to some of the largest photovoltaic manufacturing companies in the
world.

       In addition to our cell and module manufacturing solutions, we have a
device fabrication facility where we produce, under contract with our customers,
gallium arsenide (GaAs) concentrator cells. The state-of-the-art semiconductor
fabrication and foundry facility is the foundation of our solar cell process
technology for silicon, polysilicon, thin film and GaAs concentrator cells.
Under the name Spire Semiconductor, this division produces GaAs concentrator
cells, high performance LEDs, and other custom semiconductor foundry services
for our customers.

       In July 2007, we entered into a joint venture with Gloria Solar Co.,
Ltd., a leading module manufacturer in Taiwan, which designs, sells and manages
installations of photovoltaic systems. Our 45% ownership stake in the joint
venture, Gloria Spire Solar, LLC, was obtained through the contribution of our
integrated photovoltaic business to Gloria Solar. This transaction has allowed
us to focus more of our attention on our core solar business, while continuing
to expand the Spire brand name in the marketplace.

       Capitalizing on our expertise in surface treatments, we also have a
biomedical division which manufactures medical devices and provides advanced
medical device surface treatment processes to our customers. Our medical device
business develops, manufactures and sells premium products for vascular access
in chronic kidney disease patients. Our surface treatment business modifies the
surfaces of medical devices to improve their performance.

       We have been in the solar business for over 30 years and have been active
in research and development in the space, with over $100 million of research and
development conducted which has led to over 60 patents granted to date, as well

                                       13

as cell and module production, having been a pioneer in the early development of
solar technology. This expertise has provided the platform and expertise for our
manufacturing equipment. We have equipment deployed in approximately 50
countries.

       Operating results will depend upon revenue growth and product mix, as
well as the timing of shipments of higher priced products from our solar
equipment line. Export sales, which amounted to 61% of net sales and revenues
for the six months ended June 30, 2008, continue to constitute a significant
portion of our net sales and revenues.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

       Selling, general and administrative expense increased 75% in the three
months ended June 30, 2008 as compared to the three months ended June 30, 2007,
primarily as a result of an increase in stock-based compensation, marketing
activities, professional services used by us and higher head count and related
employee costs. In addition, commissions to our network of independent sales
representatives related to sales of solar equipment were up due to increased
sales and revenues. Selling, general and administrative expense decreased to 30%
of sales and revenues in 2008 as compared to 33% in 2007. The reduction was
primarily due to the absorption of overhead related costs by the 97% increase in
sales and revenues.

       Operating expenses includes approximately $163,000 and $117,000 of
stock-based compensation for the three months ending June 30, 2008 and 2007,
respectively.

INTERNAL RESEARCH AND DEVELOPMENT

       Internal research and development expense increased 119% in the three
months ended June 30, 2008 as compared to the three months ended June 30, 2007,
primarily as a result of our cost sharing contract with the National Renewable
Energy Laboratory ("NREL") reducing 2007 costs. In addition, Spire Semiconductor
had higher head count and related employee costs for the period. As a percentage
of sales and revenue, however, internal research and development expenses
remained at 1% for both periods.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

       Selling, general and administrative expense increased 50% in the six
months ended June 30, 2008 as compared to the six months ended June 30, 2007,
primarily as a result of an increase in stock-based compensation, marketing
activities, professional services used by us and higher head count and related
employee costs. In addition, commissions to our network of independent sales
representatives related to sales of solar equipment were up due to increased
sales and revenues. Selling, general and administrative expense decreased to 28%
of sales and revenues in 2008 as compared to 38% in 2007. The reduction was
primarily due to the absorption of overhead related costs by the 104% increase
in sales and revenues.

       Operating expenses includes approximately $314,000 and $181,000 of
stock-based compensation for the six months ending June 30, 2008 and 2007,
respectively.

INTERNAL RESEARCH AND DEVELOPMENT

       Internal research and development expense increased 130% in the six
months ended June 30, 2008 as compared to the six months ended June 30, 2007,
primarily as a result of our cost sharing contract with the NREL reducing 2007
costs. In addition, Spire Semiconductor had higher head count and related
employee costs for the period. As a percentage of sales and revenue, however,
internal research and development expenses remained at 1% for both periods.

OTHER INCOME (EXPENSE), NET

       We earned $2,000 and $9,000 of interest income for the three months ended
June 30, 2008 and 2007, respectively. The decreased interest income is due to
lower cash balances held by us during 2008 compared with 2007. We incurred
interest expense of $50,000 and $24,000 for the three months ended June 30, 2008
and 2007, respectively. The increased interest expense is due to higher interest
payments associated with the Equipment Credit Facility outstanding with Silicon

                                       17

Valley Bank compared with 2007 interest expenses primarily associated with
interest incurred on capital leases associated with the semiconductor foundry.
We recorded a $234,000 loss on equity investment in joint venture with Gloria
Solar for the three months ended June 30, 2008. Due to the conversion of U.S.
dollars into Japanese Yen, we lost approximately $294,000 and $4,000 during the
three months ended June 30, 2008 and 2007, respectively.

       We earned $11,000 and $53,000 of interest income for the six months ended
June 30, 2008 and 2007, respectively. The decreased interest income is due to
lower cash balances held by us during 2008 compared with 2007. We incurred
interest expense of $119,000 and $50,000 for the six months ended June 30, 2008
and 2007, respectively. The increased interest expense is due to higher interest
payments associated with the Equipment Credit Facility outstanding with Silicon
Valley Bank compared with 2007 interest expenses primarily associated with
interest incurred on capital leases associated with the semiconductor foundry.
We recorded a $364,000 loss on equity investment in joint venture with Gloria
Solar for the six months ended June 30, 2008. Due to the conversion of U.S.
dollars into Japanese Yen, we lost approximately $408,000 and $13,000 during the
six months ended June 30, 2008 and 2007, respectively.

INCOME TAXES

       We did not record an income tax benefit for the three and six months
ended June 30, 2008 and 2007. A valuation allowance has been provided against
the current period tax benefit due to uncertainty regarding the realization of
the net operating loss in the future.

NET INCOME

       We reported a net loss for the three months ended June 30, 2008 and 2007
of approximately $269,000 and $1,864,000, respectively. The net loss decreased
approximately $1,595,000 primarily due to the increase in sales and revenues and
the improvement in gross margins.

       We reported a net loss for the six months ended June 30, 2008 and 2007 of
approximately $777,000 and $3,611,000, respectively. The net loss decreased
approximately $2,834,000 primarily due to the increase in sales and revenues and
the improvement in gross margins.

       Cash and cash equivalents increased due to cash provided by operating
activities, partially offset by cash used in investing and financing activities.
The overall reduction in working capital is due to an increase in current
liabilities, partially offset by operating cash flow. We have historically
funded our operating cash requirements using operating cash flow, proceeds from
the sale and licensing of technology and proceeds from the sale of equity
securities.

       We had a $2,000,000 Loan Agreement with Citizens Bank of Massachusetts
which expired on June 26, 2007. On May 25, 2007, we and our wholly-owned
subsidiary, Spire Semiconductor, LLC, entered into a Loan and Security Agreement
(the "Equipment Credit Facility") with Silicon Valley Bank (the "Bank"). Under
the Equipment Credit Facility, for a one-year period, we and Spire Semiconductor
could borrow up to $3,500,000 in the aggregate to finance certain equipment
purchases (including reimbursement of certain previously-made purchases).
Advances made under the Equipment Credit Facility would bear interest at the
Bank's prime rate, as determined, plus 0.5% and payable in thirty-six (36)
consecutive monthly payments following the funding date of that advance.

       On March 31, 2008, we entered into a second Loan and Security Agreement
(the "Revolving Credit Facility") with the Bank. Under the terms of the
Revolving Credit Facility, the Bank agreed to provide us with a credit line up
to $5,000,000. Our obligations under the Equipment Credit Facility are secured
by substantially all of our assets and advances under the Revolving Credit
Facility are limited to 80% of eligible receivables and the lesser of 25% of the
value of our eligible inventory, as defined, or $2,500,000 if the inventory is
backed by a customer letter of credit. Interest on outstanding borrowings
accrues at a rate per annum equal to the greater of Prime Rate plus one percent
(1.0%) or seven percent (7%). In addition, we agreed to pay to the Bank a
collateral monitoring fee of $750 per month in the event we are in default of

                                       18

our covenants and agreed to the following additional terms: (i) $50,000
commitment fee; (ii) an unused line fee in the amount of 0.75% per annum of the
average unused portion of the revolving line; and (iii) an early termination fee
of 0.5% of the total credit line if we terminate the Revolving Credit Facility
prior to 12 months from the Revolving Credit Facility's effective date. The
Revolving Credit Facility, if not sooner terminated in accordance with its
terms, expires on March 30, 2009. In addition, on March 31 our existing
Equipment Credit Facility was amended whereby the Bank granted a waiver for our
defaults for not meeting our December 31, 2007 quarter liquidity and profit
covenants and for not meeting our January and February 2008 liquidity covenants.
Further, the covenants were amended to match the covenants as discussed below
contained in the Revolving Credit Facility. Our interest rate under the
Equipment Credit Facility was also modified from Bank Prime plus one half
percent to the greater of Bank Prime plus one percent (1%) or seven percent
(7%).

       On May 13, 2008, the Bank amended the Equipment Credit Facility and the
Revolving Credit Facility, modifying our net income profitability covenant
requirements in exchange for a three quarters percent (0.75%) increase in our
interest rate (7.75% at June 30, 2008) and waiver restructuring fee equal to one
half percent (0.5%) of amounts outstanding under the Equipment Credit Facility
and committed under the Revolving Credit Facility. Interest on outstanding
borrowings accrues at a rate per annum equal to the greater of Prime Rate plus
one percent (1.0%) or seven percent (7%). In addition, our term loan balance
will be factored in when calculating our borrowing base under the Revolving
Credit Facility.

       Under the amended terms of both credit facilities, as long as any
commitment remains outstanding under the facilities, we must comply with an
adjusted quick ratio covenant and a minimum monthly net income covenant. In
addition, until all amounts under the credit facilities with the Bank are
repaid, covenants under the credit facilities impose restrictions on our ability
to, among other things, incur additional indebtedness, create or permit liens on
our assets, merge, consolidate or dispose of assets (other than in the ordinary
course of business), make dividend and other restricted payments, make certain
debt or equity investments, make certain acquisitions, engage in certain
transactions with affiliates or change the business conducted by us and our
subsidiaries. Any failure by us to comply with the covenants and obligations
under the credit facilities could result in an event of default, in which case
the Bank may be entitled to declare all amounts owed to be due and payable
immediately. Our obligations under the credit facilities are secured by
substantially all of our assets.

       At June 30, 2008, we had outstanding borrowings from the Equipment Credit
Facility amounting to $2,333,000 and there were no borrowings from the Revolving
Credit Facility. We were in compliance with our covenants as of June 30, 2008.

       We maintain allowances for doubtful accounts for estimated losses
resulting from the inability of our customers to pay amounts due. We actively
pursues collection of past due receivables as the circumstances warrant.
Customers are contacted to determine the status of payment and senior accounting
and operations management are included in these efforts as is deemed necessary.
A specific reserve will be established for past due accounts when it is probable
that a loss has been incurred and we can reasonably estimate the amount of the
loss. We do not record an allowance for government receivables and invoices
backed by letters of credit as realizeability is reasonably assured. Bad debts
are written off against the allowance when identified. There is no dollar
threshold for account balance write-offs. While rare, a write-off is only
recorded when all efforts to collect the receivable have been exhausted and only
in consultation with the appropriate business line manager.

       There are no material commitments by us for capital expenditures. At June
30, 2008, our accumulated deficit was approximately $12,219,000, compared to
accumulated deficit of approximately $11,442,000 as of December 31, 2007.

       We have an effective shelf registration statement on file with the
Securities and Exchange Commission allowing us to sell up to $60 million of
common stock. We believe it is prudent to maintain shelf registration capacity
in order to facilitate future capital raising activities. To date there have
been no issuances of common stock under this shelf registration statement.

       We believe we have sufficient resources to finance our current operations
for the foreseeable future from operating cash flow and working capital. We may,
however, raise additional capital through the sale of equity or equity-related
securities, under the shelf registration statement or otherwise, under
appropriate circumstances.

Foreign Currency Fluctuation
----------------------------

       We sell only in U.S. dollars, generally against an irrevocable confirmed
letter of credit through a major United States bank. Accordingly, we are not
directly affected by foreign exchange fluctuations on our current orders.
However, fluctuations in foreign exchange rates do have an effect on our
customers' access to U.S. dollars and on the pricing competition on certain
pieces of equipment that we sell in selected markets. We received Japanese yen

                                       19

in exchange for the sale of a license to our solar technology. In addition,
purchases made and royalties received under our Consortium Agreement with our
Japanese partner are in Japanese yen. We have committed to purchase certain
pieces of equipment from European vendors; these commitments are denominated in
Euros. We bear the risk of any currency fluctuations that may be associated with
these commitments. We attempt to hedge when possible known transactions to
minimize foreign exchange risk.

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

       We subleased 77,000 square-feet in a building leased by Mykrolis
Corporation, who in turn leased the building from SPI-Trust, a Trust of which
Roger Little, our Chairman of the Board, Chief Executive Officer and President,
is the sole trustee and principal beneficiary. 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 sublease agreement provided for minimum rental payments
plus annual increases linked to the consumer price index. Effective December 1,
2005, we entered into a two-year Extension of Lease Agreement (the "Lease
Extension") directly with SPI-Trust.

       We assumed certain responsibilities of Mykrolis, the tenant under the
former lease, as a result of the Lease Extension including payment of all
building and real estate related expenses associated with the ongoing operations
of the property. We will allocate a portion of these expenses to SPI-Trust based
on pre-established formulas utilizing square footage and actual usage where
applicable. These allocated expenses will be invoiced monthly and be paid
utilizing a SPI-Trust escrow account of which we have sole withdrawal authority.
SPI-Trust is required to maintain three (3) months of its anticipated operating
costs within this escrow account. On December 1, 2006, we and SPI-Trust amended
the Lease Extension to include the lease of an additional 15,000 square feet
from SPI-Trust for a one-year term. The additional space was leased at a rate of
$8.06 per square foot on annual basis. The additional space was used to expand
our solar operations.

       On November 30, 2007, we entered into a new Lease Agreement (the "New
Lease") with SPI-Trust, with respect to 144,230 square feet of space comprising
the entire building in which we have occupied space since December 1, 1985. The
term of the New Lease commenced on December 1, 2007 and continues for five (5)
years until November 30, 2012. We have the right to extend the term of the New
Lease for an additional five (5) year period. The annual rental rate for the
first year of the Lease is $12.50 per square foot on a triple net basis, whereby
the tenant is responsible for operating expenses, taxes and maintenance of the
building. The annual rental rate increases on each anniversary by $0.75 per
square foot. If we exercises our right to extend the term of the New Lease, the
annual rental rate for the first year of the extended term will be the greater
of (a) the rental rate in effect immediately preceding the commencement of the
extended term or (b) the market rate at such time, and on each anniversary of
the commencement of the extended term the rental rate will increase by $0.75 per
square foot. We believe that the terms of the New Lease are commercially
reasonable. Rent expense under the New Lease for the three and six months ended
June 30, 2008 was $505,000 and $1,010,000, respectively.

       In conjunction with our acquisition of Spire Semiconductor in May 2003,
SPI-Trust purchased from Stratos Lightwave, Inc. (Spire Semiconductor's former
owner) the building that Spire Semiconductor occupies in Hudson, New Hampshire
for $3.7 million. Subsequently, we entered into a lease for the building (90,000
square feet) with SPI-Trust whereby we agreed to pay $4.1 million to the
SPI-Trust over an initial five-year term expiring in May 2008 with an option for
us to extend for five years. In addition to the rent payments, the lease
obligates us to keep on deposit with SPI-Trust the equivalent of three months
rent ($304,000 as of June 30, 2008.) The lease agreement does not provide for a
transfer of ownership at any point. Interest costs were assumed at 7%. Interest
expense was approximately $1,600 for the three months ended June 30, 2008. This
lease has been classified as a related party capital lease and a summary of
payments (including interest) follows:

       Upon the expiration of the lease in May 2008, we did not exercise our
option to extend the lease for an additional 5 years. On May 20, 2008, we agreed
with SPI-Trust to continue the current lease, under the current terms and
conditions on a month-to-month basis for a maximum of three (3) months beyond
the current term, up to August 23, 2008.

Critical Accounting Policies
----------------------------

       The preparation of financial statements in accordance with accounting
principles generally accepted in the United States requires us to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Among the significant estimates affecting our consolidated
financial statements are those relating to revenue recognition, reserves for
doubtful accounts and sales returns and allowances, reserve for excess and
obsolete inventory, impairment of long-lived assets, income taxes, and warranty
reserves. We regularly evaluate our estimates and assumptions based upon
historical experience and various other factors that it believes to be
reasonable under the circumstances, the results of which form the basis for
making judgments about the carrying values of assets and liabilities that are
not readily apparent from other sources. To the extent actual results differ
from those estimates, our future results of operations may be affected. We
believe the following critical accounting policies affect our more significant
judgments and estimates used in the preparation of our consolidated financial
statements. Refer to Footnote 2 of the notes to consolidated financial
statements in our Annual Report on Form 10-K for the year ended December 31,
2007 for a description of our significant accounting policies.

REVENUE RECOGNITION

       We derive our revenues from three primary sources: (1) commercial
products including, but not limited to, solar energy manufacturing equipment,
solar energy systems and hemodialysis catheters; (2) biomedical and
semiconductor processing services; and (3) United States government funded
research and development contracts.

       We generally recognizes product revenue upon shipment of products
provided there are no uncertainties regarding customer acceptance, persuasive
evidence of an arrangement exists, the sales price is fixed or determinable, and
collectibility is reasonably assured. These criteria are generally met at the
time of shipment when the risk of loss and title passes to the customer or
distributor, unless a consignment arrangement exists. Revenue from consignment
arrangements is recognized based on product usage indicating sales are complete.

       We utilize a distributor network to market and sell our hemodialysis
catheters domestically. We generally recognizes revenue when the catheters are
shipped to our distributors. Gross sales reflect reductions attributable to
customer returns and various customer incentive programs including pricing
discounts and rebates. Product returns are permitted in certain sales contracts
and an allowance is recorded for returns based on our history of actual returns.
Certain customer incentive programs require management to estimate the cost of
those programs. The allowance for these programs is determined through an
analysis of programs offered, historical trends, expectations regarding customer
and consumer participation, sales and payment trends, and experience with
payment patterns associated with similar programs that had been previously
offered. An analysis of the sales return and rebate activity for the three
months ended June 30, 2008, is as follows:

                                     Rebates        Returns         Total
                                    ---------      ---------      ---------
       Balance - March 31, 2008     $  86,000      $  10,000      $  96,000
         Provision                    123,000          8,000        131,000
         Utilization                 (113,000)        (9,000)      (122,000)
                                    ---------      ---------      ---------
       Balance - June 30, 2008      $  96,000      $   9,000      $ 105,000
                                    =========      =========      =========

       o    Credits for rebates are recorded in the month of the actual sale.
       o    Credits for returns are processed when we receive the actual
            returned merchandise.
       o    Substantially all rebates and returns are processed no later than
            three months after our original shipment.

       The reserve percentage of inventory held by distributors over the past
quarters has increased to approximately 10.5% at June 30, 2008, when compared to
8% at December 31, 2007. We perform various sensitivity analyses to determine
the appropriate reserve percentage to use. To date, actual quarterly reserve
utilization has approximated the amount provided. The total inventory held by
distributors was approximately $912,000 at June 30, 2008.

       If sufficient history to make reasonable and reliable estimates of
returns or rebates does not exist, revenue associated with such practices is
deferred until the return period lapses or a reasonable estimate can be made.

                                       21

This deferred revenue will be recognized as revenue when the distributor reports
to us that it has either shipped or disposed of the units (indicating that the
possibility of return is remote).

       Our OEM capital equipment solar energy business builds complex customized
machines to order for specific customers. Most of these orders are sold on a FOB
Bedford, Massachusetts (or EX-Works Factory) basis. It is our 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 our
environment. 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. For arrangements with multiple elements,
we allocate fair value to each element in the contract and revenue is recognized
upon delivery of each element. If we are not able to establish fair value of
undelivered elements, all revenue is deferred.

       We recognize revenues and estimated profits on long-term government
contracts on the accrual basis where the circumstances are such that total
profit can be estimated with reasonable accuracy and ultimate realization is
reasonably assured. We accrue revenue and profit utilizing the percentage of
completion method using a cost-to-cost methodology. A percentage of the contract
revenues and estimated profits is determined utilizing the ratio of costs
incurred to date to total estimated cost to complete on a contract by contract
basis. 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 United States government performs an audit of the cost
incurred under the contract. Our policy is to take into revenue the full value
of the contract, including any retainage, as we perform against the contract
because we have not experienced any substantial losses as a result of audits
performed by the United States government.

IMPAIRMENT OF LONG-LIVED ASSETS

       Long-lived assets, including fixed assets and intangible assets, are
continually monitored and are evaluated at least annually for impairment. The
determination of recoverability is based on an estimate of undiscounted cash
flows expected to result from the use of an asset and its eventual disposition.
The estimate of cash flows is based upon, among other things, certain
assumptions about expected future operating performance. Our estimates of
undiscounted cash flows may differ from actual cash flows due to, among other
things, technological changes, economic conditions, changes to our business
model or changes in our operating performance. If the sum of the undiscounted
cash flows (excluding interest) is less than the carrying value, we recognize an
impairment loss, measured as the amount by which the carrying value exceeds the
fair value of the asset.

STOCK-BASED COMPENSATION

       On January 1, 2006, we adopted the fair value recognition provisions of
Financial Accounting Standards Board ("FASB") Statement No. 123(R), Share-Based
Payment ("Statement 123(R)") using the modified prospective method. In
accordance with the modified prospective method, we have not restated our
consolidated financial statements for prior periods. Under this transition
method, stock-based compensation expense includes stock-based compensation
expense for all of our stock-based compensation awards granted prior to, but not
yet vested as of, January 1, 2006, based on the grant-date fair value estimated
in accordance with the provisions of FASB Statement No. 123, Accounting for
Stock-Based Compensation ("Statement 123"). Stock-based compensation expense for
all stock-based compensation awards granted on or after January 1, 2006 is based
on the grant-date fair value estimated in accordance with the provisions of
Statement 123(R). The impact of Statement 123(R) on our results of operations
resulted in recognition of stock option expense of approximately $213,000 and
$137,000 for the three months ended June 30, 2008 and 2007, respectively. Stock
option expense was $409,000 and $208,000 for the six months ended June 30, 2008
and 2007, respectively.

       Total foreign exchange loss for the quarter ended June 30, 2008 of
approximately $294,000 is reflected in other income (expense), net in the
accompanying unaudited condensed consolidated statement of operations.

       Outstanding letters of credit totaled approximately $250,000 at June 30,
2008. The letters of credit principally secure performance obligations, and
allow holders to draw funds up to the face amount of the letter of credit if we
do not perform as contractually required. These letters of credit expire through
2008 and are 100% secured by cash.


ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

       Market risk to which we are subject consists of the risk of loss arising
from adverse changes in market interest rates and foreign exchange rates.
Exposure to market rate risk for changes in interest rates relates to our
investment portfolio. We have not used derivative financial instruments in our
investment portfolio. We seek to place our investments with high-quality issuers
and we have policies limiting, among other things, the amount of credit exposure
to any one issuer. We seek to limit default risk by purchasing only
investment-grade securities. We do not believe we have any material market risk
with respect to our financial instruments.


ITEM 4T. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures
------------------------------------------------

       Our management, under the supervision of and with the participation of
the Chief Executive Officer and Chief Financial Officer, performed an evaluation
of the effectiveness of our disclosure controls and procedures (as defined in
Rules 13a-15(e) under the Securities Exchange Act of 1934 (the "Exchange Act"))
as of the end of the period covered by this report, June 30, 2008.

       Based on its evaluation, and taking into consideration the material
weaknesses in internal control over financial reporting referenced below, our
management, including the Chief Executive Officer and Chief Financial Officer,
concluded that our disclosure controls and procedures were not effective as of
June 30, 2008.

       As previously reported in our Annual Report on Form 10-K, as filed with
the Securities and Exchange Commission (SEC) on March 31, 2008, in connection
with our assessment of the effectiveness of our internal control over financial
reporting at the end of our last fiscal year, management identified material
weaknesses in the internal control over financial reporting as of December 31,
2007.

                                       23

       We had an ineffective control environment. This has been previously
disclosed in prior filings. Efforts to remediate deficiencies were impeded by an
evolving control environment brought on by the rapid expansion in our business
over the past twelve months. We did not maintain an effective financial
reporting process, ensure timely and accurate completion of financial statements
and we did not maintain effective monitoring controls including reconciliations
and analysis of key accounts. We did not have a sufficient level of staffing
with the necessary knowledge, experience and training to ensure the completeness
and accuracy of our financial statements. Specifically, the financial reporting
organization structure was not adequate to support the size, complexity or
activities of our Company.

       This affected our ability to maintain effective monitoring controls and
related segregation of duties over automated and manual transactions processes.
Specifically, inadequate segregation of duties led to untimely identification
and resolution of accounting and disclosure matters and failure to perform
timely and effective supervision and reviews. We did not maintain effective
controls over our IT environment. Specifically, we did not perform a review of
restricted user access in our application software system and file server
critical worksheet directories. We lacked sufficient business continuity and
back-up polices and procedures.

       As a result of the foregoing, management concluded that our internal
control over financial reporting was not effective as of December 31, 2007.

Changes in Internal Control Over Financial Reporting
----------------------------------------------------

       Except as described below, there have been no changes during our fiscal
quarter ended June 30, 2008 in our internal control over financial reporting
that may have materially affected, or are reasonably likely to materially
affect, our internal control over financial reporting.

         Management is actively addressing the above noted material weaknesses
and other operational, financial and internal control remediation efforts are
also underway. New policies and procedures are being created and existing
policies and procedures are being reviewed and will be modified as part of our
documentation and testing of internal control over financial reporting.
Management believes these new internal control policies and procedures, when
fully implemented, along with the training of key personnel and testing of these
key controls will be effective in remediating these material weaknesses. In
February 2008, we hired a Director of Financial Reporting who will have the
primary responsibility for the financial close and reporting process and our
internal control and monitoring environment related to financial reporting. In
July 2008, we hired a Senior Financial Analyst, who will be actively involved in
the financial close and reporting process and assisting us in our remediation
efforts. We have implemented new IT policies and inventory procedures and
progress was made in addressing the controls over IT and Inventory.

         Further, the we have hired an outside consulting firm to finish our
Sarbanes-Oxley efforts started in 2007. As a smaller reporting company, our
management will perform an evaluation of our internal control over financial
reporting at the end of the year; however, our independent registered public
accounting firm is not required to issue an opinion on the design or
effectiveness on our internal control over financial reporting for the 2008
fiscal year.

                                     PART II
                                OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

       During the second quarter of 2005 a suit was filed by Arrow
International, Inc. against Spire Biomedical, Inc., our wholly owned subsidiary,
alleging patent infringement by us. The complaint claimed one of our catheter
products induced and contributed to infringement when medical professionals
inserted it. We responded to the complaint denying all allegations and filed
certain counterclaims. We also filed a motion for summary judgment, asserting
patent invalidity resulting from plaintiff's failure to follow the
administrative procedures of the U.S. Patent and Trademark Office ("USPTO"). On
August 4, 2006, the Court granted our motion and dismissed this lawsuit without
prejudice. Plaintiffs applied to revive the applicable patent, which application
was granted by the USPTO in August 2006. Plaintiffs refiled their lawsuit
against us in September 2006. We have filed our answer and resumed our defense.
We have filed summary judgment motions with the Court and a hearing date on the
motions has been set for the late fall of 2008. Based on information presently
available to us, we believe we have meritorious legal defenses with respect to
this action. If we are unsuccessful in our defenses, a portion of our product
line may be enjoined or we may need to redesign certain products to avoid future
infringement. However, if the plaintiff's patent is found valid and infringed,
the parties have already agreed to a stipulated calculation of damages based on
a pre-specified royalty rate.


ITEM 1A. RISK FACTORS

       There have been no material changes in the Risk Factors described in Part
I, Item 1A ("Risk Factors") of our Annual Report on Form 10-K for the year ended
December 31, 2007.


ITEM 2.  UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

       None.


ITEM 3.  DEFAULTS UPON SENIOR SECURITIES

       None.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
