FOR IMMEDIATE RELEASE

RESEARCH IN MOTION REPORTS PRELIMINARY FOURTH QUARTER AND YEAR-END RESULTS FOR FISCAL 2007 AND PROVIDES STATUS UPDATE

Waterloo, Ontario – Research In Motion Limited (RIM) (Nasdaq: RIMM; TSX: RIM), a world leader in the mobile communications market, today reported preliminary results for the three months and fiscal year ended March 3, 2007 (all figures in U.S. dollars). This press release will also serve as the Company’s regular, bi-weekly status update pursuant to the alternative information guidelines of the Ontario Securities Commission (the “OSC”) that would have otherwise been issued on April 13, 2007. These guidelines contemplate that the Company will normally provide bi-weekly updates on its affairs until such time as the Company is current with its filing obligations under Canadian securities laws.

The results reported today are preliminary pending the U.S. GAAP restatement related to RIM’s historical non-cash charges associated with past option grants. As previously disclosed, while the review of stock option granting practices by the Special Committee of RIM’s Board of Directors is now complete, the Special Committee and its advisors, together with the Company and the Company’s external auditors, continue to do the work necessary to complete the restatement of RIM’s previously filed financial statements and to file its interim financial statements for the second and third quarters of fiscal 2007. As previously disclosed, the Company had originally anticipated updating its filings with the Canadian securities regulatory authorities and the United States Securities and Exchange commission (the “SEC”) prior to its fiscal year end of March 3, 2007. Despite best efforts, the Company determined that additional time is required for the Company and its advisors to prepare the updated filings and for the Company’s external auditors to complete their review of those filings. It is the Company’s belief that the impact of any restatement on U.S. GAAP and adjusted operating results for fiscal 2007, including the fourth quarter, will be immaterial. RIM will file its restated financial statements as well as its financial statements for the second and third quarters of fiscal 2007, and the fiscal year ended March 3, 2007 as soon as possible. The Company has determined that the accounting impact on RIM’s most recently filed Canadian GAAP statements do not result in a material adjustment and therefore the Company does not intend to restate the previously filed Canadian GAAP financial statements.

The Company has had communications with both staff of the OSC and the SEC about its internal review. As previously disclosed, the SEC has been conducting an informal inquiry in connection with the Company’s stock option granting practices. The Company understands that the informal inquiry has been converted to a formal investigation. The Company believes that the focus of this investigation is substantially the same as the informal inquiry. The Company intends to continue to cooperate with the OSC and SEC.

Revenue for the fourth quarter of fiscal 2007 was $930.4 million, up 66% from $561.2 million in the same quarter of last year. The revenue breakdown for the quarter was approximately 73% for handhelds, 19% for service, 5% for software and 3% for other revenue. Revenue for the fiscal year ended March 3, 2007 was $3.0 billion, up 47% from $2.1 billion last year. RIM shipped approximately 6.4 million devices during fiscal 2007.

Approximately 1.02 million BlackBerry subscriber accounts were added in the quarter. At the end of the quarter, the total BlackBerry subscriber account base was approximately 8 million. Revenue and subscriber account additions will not be impacted by the restatement referenced above.

“We are extremely pleased to report record results with $3 billion of revenue generated in the fiscal year and over one million BlackBerry subscriber accounts added within the fourth quarter alone,” said Jim Balsillie, Co-CEO at Research In Motion. “We are entering fiscal 2008 with very healthy subscriber growth momentum, a strong slate of products and services, exceptional partnerships and a growing market leadership position. We look forward to building on this momentum and further extending the market opportunity for RIM and its partners in the coming year.”

Preliminary GAAP net income for the quarter was $187.9 million, or $0.99 per share diluted. Excluding regular stock option expense of $4.9 million, preliminary adjusted net income was $192.8 million, or $1.01 per share diluted. The preliminary adjusted net income and preliminary adjusted net income per share do not have any standardized meaning prescribed by GAAP and therefore are unlikely to be comparable to similar measures presented by other issuers. The adjusted measures should be considered in the context of RIM’s preliminary GAAP results.

Revenue for the first quarter of fiscal 2008 ending June 2, 2007 is expected to be in the range of $1.025 billion-$1.075 billion. Subscriber account additions in the first quarter are expected to be approximately in the range of 1.125-1.15 million. GAAP earnings per share for the first quarter are expected to be in the range of $0.99-$1.07 per share diluted. Adjusted earnings per share for the first quarter, which excludes regular stock option expense of approximately $5 million, are forecast to be in the range of $1.01-$1.09 per share diluted.

In RIM’s fiscal 2007 fourth quarter, administration expense was higher than forecast as the Company incurred legal, accounting and other professional costs in connection with the voluntary internal review undertaken by the Company of its stock option granting practices and related accounting and in connection with the restatement of the Company’s historical financial statements resulting from that review. A similar level of administration expense is also included in the forecast for the first quarter of fiscal 2008. As disclosed in the Company’s March 5, 2007 press release, Jim Balsillie and Mike Lazaridis voluntarily offered to assist RIM in defraying costs incurred in connection with the review and the restatement by contributing up to CAD $10 million (up to CAD $5 million each) of those costs. RIM’s preliminary fourth quarter and year-end accounting does not reflect the contributions to be made by Mr. Balsillie and Mr. Lazaridis, which are expected to be recorded in fiscal 2008. 

The total of cash, cash equivalents, short-term and long-term investments was $1.4 billion as at March 3, 2007, compared to $1.3 billion at the end of the previous quarter, an increase of $93 million over the prior quarter.
