In North America, net sales were $688.3 million for the first quarter of 2010, up 4% from the first quarter of 2009.

Excluding the effects of foreign currency movements, net sales were up 10%. Net sales of hardware grew 30% year over year, software sales increased 10% and services sales grew by 24% compared to the first quarter of last year, all in U.S. dollars.

Selling and administrative expenses in EMEA in the first quarter of 2010 were up 10%, or $3.5 million, compared to the first quarter of 2009 in U.S. dollars and, excluding the effects of foreign currency movements, were up $1.3 million or 3% year over year. The prior year quarter selling and administrative expenses included $1.4 million of charges related to the EMEA portion of the termination of an equity-based incentive compensation plan.

The Company’s APAC operating segment reported net sales of $43.8 million for the first quarter of 2010, up 115% from the first quarter of 2009 in U.S. dollars, 71% excluding the effects of foreign currency movements.

As a result, earnings from operations in APAC were $388,000 in the first quarter of 2010, compared to a loss from operations of $576,000 in the first quarter of 2009.

UPDATED GUIDANCE

Given the Company’s stronger than expected financial performance in the first quarter, the Company now anticipates that diluted earnings per share for the full year of 2010 will be between $1.05 and $1.15. This outlook reflects the following assumptions:

• continued strong demand for hardware technology in North America partially offset by:

• the full-year effect of partner program changes that were effective beginning in May of 2009;

• a decline in sales of services in 2010 due to the completion of a significant services engagement in 2009 that is not currently expected to be replaced fully in 2010; and

• an effective tax rate of approximately 36% - 39% for 2010, up from 26% in 2009.

This outlook does not include the impact of any severance and restructuring expenses or expenses associated with the restatement of the Company’s financial statements or related litigation.
