ITEM 2.02. Results of Operations and Financial Condition.

On July 29, 2010, the Registrant announced via a press release its preliminary results of operations for its quarter ended June 30, 2010. A copy of the press release is attached as Exhibit 99.1 hereto. It also posted on its website management’s presentation of highlights for the quarter ended June 30, 2010, a copy of which is attached as Exhibit 99.2.

Both exhibits contain references to adjusted EBITDA and free cash flow, which are considered non-GAAP financial measures.

Management believes that adjusted EBITDA and free cash flow are useful measures of operating performance because they exclude items that we do not consider indicative of our core performance. In the case of adjusted EBITDA, we adjust net income for such things as interest, taxes, stock-based compensation and certain non-cash and non-recurring items. Free cash flow subtracts from adjusted EBITDA the capitalization of content database costs, capital expenditures and cash paid for income taxes and interest expense. However, these non-GAAP measures should be considered in addition to, not as a substitute for or superior to, net income and net cash provided by operating activities, or other financial measures prepared in accordance with GAAP. A reconciliation to the GAAP equivalents of these non-GAAP measures is contained in the press release and is also posted on the Registrant’s website.

Our management uses adjusted EBITDA and free cash flow as measures of operating performance; for planning purposes, including the preparation of our annual operating budget; to allocate resources to enhance the financial performance of our business; to evaluate the effectiveness of our business strategies; to provide consistency and comparability with past financial performance; to facilitate a comparison of our results with those of other companies; and in communications with our board of directors concerning our financial performance. We also use adjusted EBITDA and have used free cash flow as factors when determining management’s incentive compensation.

The information in this report shall not be treated as filed for purposes of the Securities Exchange Act of 1934, as amended.
