</TABLE>

       The decline in manufacturing equipment sales for the three and six month
periods ended June 30, 1999 is primarily due to limited capacity expansion in
photovoltaic module production. The decline in contract research, service and
license revenues for the three and six month periods ended June 30, 1999 is
primarily due to a decline in new awards experienced during the latter part of
1998 as more of the Company's development efforts went toward commercial
products. The Company's inability to complete a commercial order on schedule
delayed revenue on that order and caused the Company to incur substantial
non-reimbursable cost, which otherwise would have been applied to chargeable
contract research activities.

and from cost reductions implemented by the Company in 1998.


LIQUIDITY AND CAPITAL RESOURCES

       To date the Company has been able to fund its liquidity requirements
using cash from operations and available lines of credit. On March 19, 1999, the
Company amended and extended its revolving credit agreement with Silicon Valley
Bank. This agreement provides for a $2 million revolving credit facility, based
upon eligible accounts receivable requirements. This line of credit has been
established to provide 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. Interest on the line is at the Bank's
prime rate plus one percent. The line contains covenants including provisions
relating to profitability and net worth. As of June 30, 1999, the Company was in
default under this line, but has agreed to a new credit facility which resets
the covenant and expands debt capacity. As of June 30, 1999, the Company had
$1,400,000 outstanding debt under this revolving credit facility.

       Cash and cash equivalents increased $237,000 to $359,000 at June 30,
1999, from $122,000 at December 31, 1998. To date there are no material
commitments by the Company for capital expenditures. At June 30, 1999, the
Company's accumulated deficit was $2,886,000, compared to an accumulated deficit
of $2,179,000 as of December 31, 1998. Working capital as of June 30, 1999
decreased 49% to $768,000, compared to $1,501,000 as of December 31, 1998.
Although no assurances can be made, the Company expects that cash flow from
operations, the existing line of credit with its bank, and available lease
arrangements, will be sufficient to meet its needs for working capital. However,
the Company believes it has insufficient capital resources for business
expansion. The Company has taken steps to conserve its resources by reducing its
cost of operations. In addition, the Company is exploring ways to increase
capital through possible increased debt, equity, or sale of part or all of the
Company. The Company has engaged the investment banking firms of Laird & Company
and OEM Capital to assist in this endeavor.


RECENT ACCOUNTING PRONOUNCEMENTS

       In June 1998, the Financial Accounting Standards Board issued SFAS 133,
"Accounting for Derivative Instruments and Hedging Activities", which
establishes accounting and reporting standards for derivative instruments,
including certain derivative instruments embedded in other contracts
(collectively referred to as "derivatives") and for hedging activities. This
statement requires that an entity recognize all derivatives as either assets or
liabilities in the balance sheet and measure those instruments at fair value.
The statement also sets forth the criteria for determining whether a derivative
may be specifically designed as a hedge of a particular exposure with the intent
of measuring the effectiveness of that hedge in the statement of operations. In
July 1999, the Financial Accounting Standards Board issued SFAS 137 which
deferred the effective date of SFAS 133 to fiscal quarters of fiscal years
beginning after June 15, 2000. Management does not believe that the adoption of
this statement will have a material impact on the Company's consolidated
financial position, results of operations or cash flows.

IMPACT OF INFLATION AND CHANGING PRICES

       Historically, the Company's business has not been materially impacted by
inflation. Manufacturing equipment sales 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 U.S. 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.


IMPACT OF THE YEAR 2000 ISSUE

       The Company has identified the potential impact of the Year 2000 issue.
The Year 2000 issue relates to computer programs and embedded computer chips
being viable to distinguish between the year 1900 and the year 2000.

       The Company has completed a review and assessment of potentially affected
items, including information technology and non-information technology, for Year
2000 compliance. When identifying computer programs that were not Year 2000
compliant, the Company sought to upgrade these programs to newer versions of
software that are Year 2000 compliant. The Company's main business system's
upgrade to Y2K compliant software has been installed. Data files will be
converted during the third quarter of 1999. The Company has obtained required
software. The cost of the software is estimated to not exceed $50,000.

       The Company's business is also dependent upon systems of third parties,
primarily its vendors and customers. The Company has submitted questionnaires to
all of its significant vendors. The Company has analyzed their responses, and no
known problems have been identified. The Company issued questionnaires to its
customer base, and has completed an analysis of its customer base. No known
problems have been identified.

       The Company believes that its most likely and reasonable worst case
scenario relating to the Year 2000 would be failure of certain of its
applications with imbedded software or failure of such applications of a
material customer or vendor. Failure of applications of embedded software could
result in a disruption of the Company's operation and thereby negatively affect
revenues and profitability. Failure of a significant vendor's information
systems could temporarily interrupt supply of materials or services and impair
the Company's ability to fill orders. If a major customer system fails to become
Year 2000 compliant, the Company's revenues could be temporarily disrupted if
the customer suspends further purchases. Although there can be no assurance that
these failures will not have an adverse effect on the Company's business, the
Company believes that any such adverse effect would not be material.

       The Company is formulating contingency plans to address any such
failures. The plans include identifying Year 2000 compliant software for the
Company's internal systems, and identifying alternative vendors to assure
continuity of supplies.
