                             MATERIAL CHANGE REPORT


1.       Name and Address of Company

         Research In Motion Limited (the "Company" or "RIM")
         295 Phillip Street
         Waterloo, Ontario
         N2L 3W8

2.       Date of Material Change

         September 28, 2006.

3.       News Release

         Two news releases were issued in Waterloo, Ontario on September 28,
         2006 through the newswire services of CCN Matthews and Market Wire,
         copies of which are annexed hereto as Schedule "A".

4.       Summary of Material Change

         RIM announced on September 28, 2006 that the Audit Committee of RIM's
         Board of Directors, comprised solely of independent directors, is
         completing a management-initiated, voluntary review of RIM's
         historical option granting practices. RIM announced that the Audit
         Committee has made a preliminary determination that GAAP accounting
         errors were made around the administration of certain historical stock
         options granted from fiscal 1998 to present, and has made a
         preliminary determination that a restatement of RIM's historical
         financial statements will be required to reflect this. Although the
         review is ongoing, it is currently expected that the potential effect
         of such restatement will be to increase the amount of non-cash charges
         associated with past option grants and thereby reduce the amount of
         the Company's previously reported GAAP earnings by an aggregate amount
         of approximately $25-45 million over the period since the Company's
         IPO in 1997.

         RIM also announced on September 28, 2006 preliminary second quarter
         results for the three months ended September 2, 2006. The results
         reported on September 28, 2006 were preliminary pending a potential
         restatement related to RIM's historical non-cash charges associated
         with past option grants. It is the Company's belief that the potential
         impact of any restatement on GAAP and adjusted operating results for
         the first, second, and subsequent quarters of fiscal 2007, will be
         immaterial. RIM will file final financial statements for the second
         quarter of fiscal 2007 following the completion of the review. Revenue
         for the second quarter of fiscal 2007 was $658.5 million, up 7.4% from
         $613.1 million in the previous quarter and up 34.4% from $490.1
         million in the same quarter of last year. Preliminary GAAP net income
         for the quarter was $140.8 million, or $0.74 per share diluted.

5.       Full Description of Material Change

         RIM announced on September 28, 2006 that the Audit Committee of RIM's
         Board of Directors, comprised solely of independent directors, is
         completing a management-initiated, voluntary review of RIM's

         historical option granting practices. Following the heightened public
         awareness and concern regarding stock option grant practices by
         publicly traded companies, RIM elected to commence a pro-active review
         of its own practices. The Audit Committee is being assisted in this
         regard by outside legal counsel and by outside accounting consultants.
         The Audit Committee has made a preliminary determination that GAAP
         accounting errors were made around the administration of certain
         historical stock options granted from fiscal 1998 to present, and has
         made a preliminary determination that a restatement of RIM's
         historical financial statements will be required to reflect this.
         Although the review is ongoing, it is currently expected that the
         potential effect of such restatement will be to increase the amount of
         non-cash charges associated with past option grants and thereby reduce
         the amount of the Company's previously reported GAAP earnings by an
         aggregate amount of approximately $25-45 million over the period since
         the Company's IPO in 1997. The Company has voluntarily informed the
         SEC and the OSC about its internal review of its stock option grants.
         The Company does not at present anticipate a material adjustment to
         current or future fiscal years' operating results, including the
         preliminary Q2 operating results reported on September 28, 2006, and
         RIM has defined enhanced procedures and controls to address issues of
         this nature.

         RIM also announced on September 28, 2006 preliminary second quarter
         results for the three months ended September 2, 2006. The results
         reported on September 28, 2006 were preliminary pending a potential
         restatement related to RIM's historical non-cash charges associated
         with past option grants. It is the Company's belief that the potential
         impact of any restatement on GAAP and adjusted operating results for
         the first, second, and subsequent quarters of fiscal 2007, will be
         immaterial. RIM will file final financial statements for the second
         quarter of fiscal 2007 following the completion of the review.

         Revenue for the second quarter of fiscal 2007 was $658.5 million, up
         7.4% from $613.1 million in the previous quarter and up 34.4% from
         $490.1 million in the same quarter of last year. The revenue breakdown
         for the quarter was approximately 72% for handhelds, 19% for service,
         6% for software, and 3% for other revenue. Approximately 705,000
         BlackBerry subscriber accounts were added in the quarter. At the end
         of the quarter, the total BlackBerry subscriber account base was
         approximately 6.2 million. Revenue and subscriber account additions
         will not be impacted by any potential restatement referenced above.

         Preliminary GAAP net income for the quarter was $140.8 million, or
         $0.74 per share diluted. Excluding regular stock option expense of
         $4.3 million, preliminary adjusted net income was $145.1 million, or
         $0.77 per share diluted. The preliminary net income, preliminary
         adjusted net income, preliminary net income per share 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. These adjusted measures
         should be considered in the context of RIM's GAAP results.

         Revenue for the third quarter of fiscal 2007 ending December 2, 2006
         is expected to be in the range of $780-$820 million. Subscriber
         account additions in the third quarter are expected to be
         approximately 800,000. GAAP earnings per share for the third quarter
         are expected to be in the range of 88-95 cents per share diluted.
         Adjusted earnings per share for the third quarter, which excludes
         regular stock option expense of approximately $4.5 million, are
         forecast to be in the range of 90-97 cents per share diluted.

         The total of cash, cash equivalents, short-term and long-term
         investments was $1.2 billion as at September 2, 2006, compared to $1.3
         billion at the end of the previous quarter, a decrease of $100 million

                                      -3-

         over the prior quarter. Uses of cash in the quarter included a
         business acquisition, capital expenditures and common share
         repurchases.

         Certain of the statements contained in the news releases and in this
         Material Change Report constitute forward-looking statements within
         the meaning of the U.S. Private Securities Litigation Reform Act of
         1995 and applicable Canadian securities laws, and readers are urged to
         consider carefully the cautionary language regarding such-forward
         looking statements contained in each of the news releases.

         All figures in this material change report are in US dollars.

6.       Reliance on subsection 7.1(2) or (3) of National Instrument 51-102

         Not applicable.

         No significant facts have been omitted from this report.

RESEARCH IN MOTION REPORTS PRELIMINARY SECOND QUARTER RESULTS

Waterloo, Ontario - Research In Motion Limited (RIM) (Nasdaq: RIMM; TSX: RIM),
a world leader in the mobile communications market, today reported preliminary
second quarter results for the three months ended September 2, 2006 (all
figures in U.S. dollars).

The results reported today are preliminary pending a potential restatement
related to RIM's historical non-cash charges associated with past option
grants. As disclosed in a separate press release issued by RIM today, RIM is
completing a management-initiated, voluntary review of RIM's historical option
granting practices. It is the Company's belief that the potential impact of any
restatement on GAAP and adjusted operating results for the first, second, and
subsequent quarters of fiscal 2007, will be immaterial. RIM will file final
financial statements for the second quarter of fiscal 2007 following the
completion of the review.

Revenue for the second quarter of fiscal 2007 was $658.5 million, up 7.4% from
$613.1 million in the previous quarter and up 34.4% from $490.1 million in the
same quarter of last year. The revenue breakdown for the quarter was
approximately 72% for handhelds, 19% for service, 6% for software, and 3% for
other revenue. Approximately 705,000 BlackBerry subscriber accounts were added
in the quarter. At the end of the quarter, the total BlackBerry subscriber
account base was approximately 6.2 million. Revenue and subscriber account
additions will not be impacted by any potential restatement referenced above.

"We are very pleased to report strong financial performance and momentum in our
second quarter," said Jim Balsillie, Chairman and Co-CEO at RIM. "The second
half of the fiscal year is promising to be one of the most interesting periods
in our history with the launch of exciting new products, including the
BlackBerry Pearl, on networks around the world. Our technology and business
strategies continue to open new markets for RIM and expand our opportunities
for growth."

Preliminary GAAP net income for the quarter was $140.8 million, or $0.74 per
share diluted. Excluding regular stock option expense of $4.3 million,
preliminary adjusted net income was $145.1 million, or $0.77 per share diluted.
The preliminary net income, preliminary adjusted net income, preliminary net
income per share 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. These adjusted
measures should be considered in the context of RIM's GAAP results.

Revenue for the third quarter of fiscal 2007 ending December 2, 2006 is
expected to be in the range of $780-$820 million. Subscriber account additions
in the third quarter are expected to be approximately 800,000. GAAP earnings
per share for the third quarter are expected to be in the range of 88-95 cents
per share diluted. Adjusted earnings per share for the third quarter, which
excludes regular stock option expense of approximately $4.5 million, are
forecast to be in the range of 90-97 cents per share diluted.

Note: Preliminary adjusted net income and preliminary adjusted net income per

comparable to similar measures presented by other issuers. Investors are

results.
