ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS FOR THE THREE MONTHS ENDED MARCH 31, 1996 AND 1995

SALES

Sales for the first quarter 1996 were $27.2 million, an increase of 51% from first quarter 1995 sales of $18 million. The Company's sales growth during the periods presented has resulted from the increased unit sales of the Company's systems. A significant part of this growth is attributable to increased sales to domestic customers, primarily the Company's two largest customers, which in the quarter reported on accounted for approximately 54% of the company's revenue.

GROSS MARGIN

The Company's gross margin in the first quarter was 37.3% of revenue, down from 46.3% of revenue in the comparable period in 1995 and down from 43.3% in the fourth quarter of 1995. The gross margin in the first quarter 1996 was primarily affected by higher costs associated with outsourcing assemblies, changes in product mix, and costs associated with expanding into additional manufacturing facilities. Average selling prices remained relatively constant. The Company is accelerating implementation of its program to review all outsourcing contracts, to re-negotiate prices with outsourcing vendors and to re-evaluate prior decisions to outsource certain assemblies. The Company is also analyzing its internal manufacturing overhead structure to compare it with the current ratio of outsourced to in-house built assemblies.

RESEARCH AND DEVELOPMENT

The Company's research and development costs are associated with researching new technologies, developing new products and improving existing product designs. Research and development expenses for the first quarter 1996 were $3.5 million, compared to first quarter 1995 expenses of $2.1 million, representing an increase of 69%. As a percentage of sales, research and development expenses increased from 11.4% in the first quarter 1995 to 12.9% in the first quarter 1996. The increase in expenses from 1995 to 1996 is primarily associated with increases in payroll costs, business travel, outside service costs and materials costs incurred to support new product development.

The Company believes that continued research and development investment is essential to ongoing development of new products. Since inception, all research and development costs have been internally funded and expensed.

SALES AND MARKETING

Sales and marketing expenses support domestic and international sales and marketing activities which include personnel, trade shows, advertising, and other marketing activities. Sales and marketing expenses were $1.3 million and $2.1 million for the first quarter 1995 and the first quarter 1996, respectively. This represented a 59% increase from 1995 to 1996. As a percentage of sales, these expenses increased from 7.2% in the first quarter 1995 to 7.7% in the first quarter 1996. The increase is attributable to increases in payroll, promotional materials, advertising, commissions and travel costs associated with expansion to support the increase in sales volume.

The Company is reorganizing its sales and marketing team to better address the specific needs of its customers. To accomplish this, the Company plans to hire personnel for certain senior and staff level positions in sales and marketing and to open support offices in Korea and Taiwan during 1996. As a result, sales and marketing expenses are expected to increase as a percentage of sales in future periods.

GENERAL AND ADMINISTRATIVE

General and administrative expenses support the worldwide financial, administrative, information systems and human resources functions of the Company. General and administrative expenses were $1.7 million in both the first quarter 1995 and in the first quarter 1996. As a percentage of sales, these expenses decreased from 9.2% in the first quarter 1995 to 6.3% in the first quarter 1996.

The Company is currently implementing information management system software which will replace existing systems to support its growth. The Company expects that significant charges related to training and implementation of the new software will occur during 1996.

OTHER INCOME (EXPENSE)

Other income and expenses consist primarily of foreign exchange gains and losses, interest expense and other miscellaneous income and expense items. Other expenses were $0.2 million for the first quarter 1996, compared to $0.1 million in the first quarter 1995. In both periods under consideration other expense was 0.6% of revenue.

PROVISION FOR INCOME TAXES

The income tax provision of $1.0 million for the first quarter 1996 represented an estimated effective rate of 37.0%. The income tax provision in the comparable period in 1995 was $1.2 million, representing an estimated rate of 38.2%.

LIQUIDITY AND CAPITAL RESOURCES

Until the initial public offering of the Company's common stock in November, 1995, the Company financed its operations, acquired equipment and met its working capital requirements through borrowings under its revolving line of credit, long-term loans secured by property and equipment and cash flow from operations.

Cash provided by operations totaled $0.1 million for the first quarter in 1996 compared to cash provided of $0.3 million for the same period in 1995. Cash provided in both periods was primarily a result of net income and increases in accounts payable offset by increases in accounts receivable and inventories.

Investing activities, consisting primarily of equipment acquisitions and leasehold improvements, used cash of $3.1 million. Financing activities, consisting primarily of note and loan repayments, offset by proceeds from exercise of stock options and warrants, used cash of $0.1 million.

The Company plans to spend approximately $3.5 million through the remainder of 1996 for the acquisition of equipment and integrated information management system software, leasehold improvements and furnishings.

As of March 31, 1996, the Company had working capital of $32.6 million. The Company's principal sources of liquidity consisted of $10.1 million of cash and cash equivalents, $8.0 million available under a $8.0 million revolving line of credit that bears interest at prime rate (8.25% at April 15, 1996). The Company has the option to convert up to $3.0 million of its revolving line of credit to a 36-month term loan that would bear interest at prime rate plus 0.50%.

The Company also has a term loan for equipment financing. At March 31, 1996, $1.5 million was outstanding under the term loan, which bears interest at prime plus 0.75% and is due July 31, 1999. The Company also has entered into an agreement, effective November 17, 1995, that provides the Company with a $1.5 million line of credit to purchase equipment. At March 31, 1996, there were no amounts outstanding under this line of credit.

The Company believes that its cash and cash equivalents, cash flow from operations and available borrowings, will be sufficient to meet the Company's working capital needs through at least the end of 1996. After that time, the Company may require additional equity or debt financing to address its working capital, capital equipment, or expansion needs. There can be no assurance that additional funding will be available when required or that it will be available on terms acceptable to the Company.
