For the first six months of 2010, revenues were $44.1 million, the operating loss was $4.9 million and the net loss was $5.1 million, or $0.26 per diluted share. This compares with revenues of $37.9 million, an operating loss of $0.9 million and a net loss of $0.4 million, or $0.02 per diluted share, in the first six months of 2009.

On a non-GAAP basis, the Company had operating income of $0.02 million and a net loss of $0.2 million or $0.01 per diluted share for the first six months of 2010. This compares with operating income of $1.3 million and net income of $2.1 million or $0.11 per diluted share for the first six months of 2009.

The reconciliation between GAAP net income and Non-GAAP net income is provided in the tables at the end of this release.

Total revenues for the second quarter of 2010 consisted of $19.2 million for the Networking Business Unit (NBU) and $4.1 million for the Technology Business Unit (TBU). This compares with $15.0 million for the NBU and $4.6 million for the TBU reported in the second quarter of 2009.

The Company’s forecast for the second quarter of 2010, presented on April 28, was for revenues of $22.0 million (consisting of NBU revenues of $18.0 million and TBU revenues of $4.0 million), non-GAAP operating income of $0.1 million and non-GAAP net income of $0.1 million or $0.01 per diluted share.

The Company ended the second quarter of 2010 with approximately $122.2 million in cash and liquid investments, equivalent to $6.26 per basic share, a decrease of $1.1 million from March 31, 2010. The decrease reflects $0.4 million used for operating activities and $0.8 million used for capital expenditures offset by $0.1 million from the exercise of options.

Boaz Raviv, Chief Executive Officer, commented: “Our second quarter revenue growth reflects better than expected performance by our NBU and TBU. The continued success of our SCOPIA Elite platform drove strong infrastructure sales in our NBU, including with Cisco. We have now introduced further advancements to the SCOPIA Elite in its telepresence interoperability as well as in video conferencing control through SCOPIA Mobile, a free application for Apple devices.

“Our second quarter growth also included important ramp-up in our revenues from endpoints, which exceeded 10% of second quarter NBU revenues and included initial sales of the SCOPIA XT1000 high definition room conferencing system, with shipment beginning only a few days before quarter-end. Market response and initial demand were stronger than we expected.”

Mr. Raviv concluded: “The addition of endpoint products to our product offerings has transformed our position in the video marketplace. We are now an end-to-end video conferencing solutions company, with a portfolio of solutions distinguished by high performance, pricing, superior interoperability and ease of use. We have seen the tangible results in the accelerated expansion of our reseller channel and our success in competitive bids. We plan to move forward from here through further channel expansion and technology development, with our roadmap focused on delivering advanced solutions with distinguishing features that will help broaden the video conferencing market.”

GAAP versus NON-GAAP Presentation

To supplement the consolidated financial statements presented in accordance with generally accepted accounting principles in the United States (“GAAP”), the Company uses non-GAAP measures of operating results, net income and earnings per share, which are adjusted from results based on GAAP to exclude net profit and loss from other than temporary impairment of available-for-sale marketable securities, the expenses recorded for stock compensation in accordance with ASC 718, amortization of purchased intangibles, acquisition-related costs and acquisition-related restructuring expenses, net. These non-GAAP financial measures are provided to enhance overall understanding of the current financial performance and prospects for the future. Specifically, the Company believes the non-GAAP results provide useful information to both management, and investors as these non-GAAP results exclude other than temporary impairment of available-for-sale marketable securities, the expenses recorded for stock compensation in accordance with ASC 718, amortization of purchased intangibles, acquisition-related costs and acquisition-related restructuring expenses, net that the Company believes are not indicative of the core operating results. Further, these non-GAAP results are one of the primary indicators management uses for assessing the Company’s performance, allocating resources and planning and forecasting future periods. These measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for or superior to GAAP results. These non-GAAP measures may be different from the non-GAAP measures used by other companies.
