Second Quarter Net Income Rises 147% Versus 2007 Second Quarter

                 Adjusted EBITDA Rises 29.6% to $7 Million



    WEST SPRINGFIELD, Mass., Aug. 7 /EMWNews/ -- Cyalume Light

Technologies Inc. ("Cyalume"), a private company that is a leading provider

of safety, security and training products for the US military and other

militaries announced preliminary unaudited financial results for the first

six months of 2008.



    For the six month period ending June 30, 2008, Cyalume reported net

income of $2.3 million on revenues of $20.8 million. This compares with a

net loss of $106,000 on revenues of $19.4 million during the first six

months of 2007. Adjusted EBITDA rose 29.6% to $7 million compared to $5.4

million during the first six months of 2007.



    For the second quarter period ending June 30, 2008, Cyalume reported

net income of $1.3 million on revenues of $10.7 million versus net income

of $547,000 on revenues of $11.1 million for the second quarter of 2007, a

147% increase. Adjusted EBITDA rose 24.6% to $4.1 million compared to $3.3

million during the second quarter of 2007. The increase of net income and

adjusted EBITDA for the three and six month periods was due primarily to

reductions in operating expenses from the previous year as well as

increases in core product sales and ammunition sales.



    Speaking of the first six months of 2008, Derek Dunaway, CEO of Cyalume

said, "We experienced a solid increase in cash flow and net profitability

so far this year. Not only are we seeing continued strength from our core

product line, but we are seeing growth in products such as our training

ammunition. We continue on track to achieve what we believe will be

revenues of approximately $45 million in 2008, compared to $39 million in

2007, but more importantly, we expect to generate a 32% growth in adjusted

EBITDA to approximately $14.5 million in 2008 compared to $11.3 million in

2007. As our new ammunition vertical continues to roll out and gain

acceptance, we expect to see even stronger growth in revenues and

profitability in 2009 and 2010.



    On February 14, 2008, Cyalume Light Technologies agreed to be acquired

by Vector Intersect Security Acquisition Corporation (OTC Bulletin Board:

VTRQ), a special purpose acquisition company. Upon consummation of the

acquisition, Derek Dunaway, CEO of Cyalume will become Chief Executive

Officer of Vector Intersect. Yaron Eitan, currently CEO of Vector Intersect

consummation of the acquisition, Vector Intersect will change its name to

statement with the SEC in anticipation of a shareholders vote to approve

the acquisition of Cyalume by Vector.
