NEWS RELEASE for May 9, 2011

BIOLASE REPORTS FIRST QUARTER RESULTS

Revenue Guidance of $14.0 Million — $15.0 Million for Q2, up from $4.7 Million, Excluding Royalty Income of $1.2 Million, Year over Year

IRVINE, CA (May 9, 2011) — BIOLASE Technology, Inc. (NASDAQ:BLTI), the World’s leading dental laser manufacturer and distributor, today reported unaudited operating results for its first quarter ended March 31, 2011.

Net revenue for this year’s first quarter was $10.6 million, up 140 percent from $4.4 million in the same quarter for 2010 and up nine percent sequentially from $9.7 million in the 2010 fourth quarter, driven by BIOLASE’s new direct sales business model implemented during the fourth quarter. The majority of sales in the quarter were from the sale of the Company’s new flagship all-tissue laser system, the Waterlase® iPlus™, and the wireless iLase™ five watt diode laser system. Initial orders for the Waterlase iPlus received during the quarter have exceeded the Company’s expectations.

The percentage of net revenue in this year’s first quarter from the U.S. and international markets was approximately 81 percent and 19 percent, respectively, as compared to approximately 51 percent and 49 percent of net revenue in the prior year comparable period. International revenue in this year’s first quarter was negatively affected as the Company renegotiated its international exclusivity rights granted to Henry Schein, Inc. (NASDAQ:HSIC). In April 2011, BIOLASE announced that it had regained full rights to sell and/or distribute the Company’s products in all international markets which were previously exclusive markets of Schein. As a result, BIOLASE will now sell both direct and through multiple distributors, in those markets on a go-forward basis.

Federico Pignatelli, Chairman and CEO, said, “All of the commercial programs at BIOLASE are running ahead of our internal plan, and the first quarter results are emblematic of our progress. The Waterlase iPlus launch is progressing very well and the product is being enthusiastically accepted by dentists in the U.S. and internationally. We expect that the Waterlase iPlus system will be a strong contributor to revenue growth throughout 2011 and beyond. In addition, sales of the iLase remained strong through the quarter. We believe we have momentum to gain internationally in the second quarter, as we have now completed our repossession of rights to sell and distribute in international markets, and we expect to ship laser systems to these territories in this manner during the second quarter.”

Recent Highlights
A series of recent actions and key accomplishments include the following:

Pignatelli continued, “Operationally, we saw excellent performance in the period, even in an environment where our purchasing, inventory build activity, manufacturing, and testing rose to much higher levels in the face of strong product demand across our platforms. I am proud of the team effort coordinated by our leadership in sales, operations, and finance. We are working hard to carry this organic growth momentum into the second quarter, and beyond, and look forward to adding additional products within the next two quarters to support our growth. It is a challenging and very exciting time to be part of BIOLASE.”

Gross profit as a percentage of net revenue for this year’s first quarter was 46 percent compared to six percent for the prior year period. The year-over-year quarterly increase of 40 percent was primarily due to higher sales volumes, better utilization of fixed costs, and reduced expenses, partially offset by significant one-time price concessions to certain luminaries in the dental field and increased one-time costs related to the launch of the Waterlase iPlus system.

Operating expenses in the 2011 first quarter were $5.2 million, compared to $5.6 million in the year-earlier period. The year-over-year reduction in expense was primarily due to ongoing cost-cutting measures that were partially offset by increased costs associated with the launch of the Waterlase iPlus system.

Net loss for the 2011 first quarter was $750,000, or $0.03 loss per share, compared to a net loss of $5.3 million, or $0.22 loss per share, in the 2010 first quarter. As already mentioned, first quarter profitability was negatively affected by significant initial costs associated with the late January launch of the Waterlase iPlus system. After removing interest and debt-related costs of $298,000 resulting from the Company’s term loan pay-off, and non-cash expenses related to depreciation and amortization of $228,000 and stock and equity related compensation expenses of $316,000, this year’s first quarter resulted in non-GAAP net income of $92,000, or $0.00 per share. The first quarter of 2010 resulted in a non-GAAP net loss of $4.8 million, or $0.20 loss per share.

The cash and cash equivalents balance at March 31, 2011 was $1.6 million, which does not reflect the significant sales that occurred at the end of the quarter. The Company has already collected over $3.0 million of its approximately $6.0 million net accounts receivable since March 31, 2011.

The non-GAAP financial measures contained herein are a supplement to the corresponding financial measures prepared in accordance with generally accepted accounting principles (GAAP). The non-GAAP financial measures presented exclude the items summarized in the below table. Management believes that adjustments for these items assist investors in making comparisons of period-to-period operating results and that these items are not indicative of the Company’s on-going core operating performance.

Management uses non-GAAP net income (loss) and non-GAAP net income (loss) per diluted share in its evaluation of the Company’s core after-tax results of operations and trends between fiscal periods and believes that these measures are important components of its internal performance measurement process. Management believes that providing these non-GAAP financial measures allows investors to view the Company’s financial results in the way that management views the financial results.

The non-GAAP financial measures presented herein have certain limitations in that they do not reflect all of the costs associated with the operations of the Company’s business as determined in accordance with GAAP. Therefore, investors should consider non-GAAP financial measures in addition to, and not as a substitute for, or as superior to, measures of financial performance prepared in accordance with GAAP. The non-GAAP financial measures presented by the Company may be different from the non-GAAP financial measures used by other companies.
