	Q1 2010		Q1 2009		% Change
Subscriber Revenues	$	59.5 million	$	59.6 million	(0.2)%

“I am pleased that during Q1 we achieved record quarterly free cash flow while at the same time executing on our plan to expand sales and marketing efforts,” said Hemi Zucker, j2 Global’s chief executive officer. “I am also encouraged by our higher organic net customer additions, reduced cancel rate and increasing deferred revenues. I am optimistic that with an improving economy, a strong acquisition pipeline and a solid business plan and operating strategy we continue to be well positioned to grow our Company while maintaining healthy profit margins.”

SHARE REPURCHASE PROGRAM

Under the share repurchase program, the Company may purchase in the public market or in off-market transactions up to 10 million shares at any time or times through April 30, 2012. The timing and amounts of any purchases will be determined by the Company from time to time, depending on market conditions and other factors it deems relevant.

FUSEMAIL ACQUISITION

The Company has acquired substantially all of the assets of FuseMail, LLC, a provider of outsourced email and email marketing services. Terms of the acquisition were not disclosed. The financial impact to j2 Global is not expected to be material.

BUSINESS OUTLOOK

For fiscal 2010, j2 Global reaffirms its targeted revenue growth of 5% with a range of 3% to 7% compared to fiscal year 2009 revenues. Net earnings, excluding 123R non-cash compensation expense, are expected to approximate non-GAAP earnings in 2009 as the Company intends to reinvest its incremental operating income in initiatives designed to accelerate growth in 2011 and beyond.

The range of anticipated revenues takes into account both organic growth and acquisition related growth within the context of current economic conditions.

UNAUDITED RECONCILIATION OF MODIFIED NET EARNINGS

THREE MONTHS ENDED MARCH 31, 2010 AND 2009

(UNAUDITED, IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)

Modified net earnings are GAAP net earnings with the following modifications (1) elimination of share-based compensation expense for 2010 and 2009; (2) elimination of certain acquisition costs; (3) income tax expense associated with share-based compensation and certain acquisition costs.

Modified net earnings and modified net earnings per share are not meant as a substitute for measures determined under GAAP, but are solely for informational purposes. The following table illustrates and reconciles the GAAP net earnings with the aforementioned exclusions. The Company believes that this non-GAAP financial information are useful measures of operating performance because they exclude certain non-recurring transactions outside the ordinary course of the Company's business.
