                              NOTICE OF INTENTION
                             TO MAKE AN ISSUER BID


<PAGE>

1.   Name of Issuer:

     Research In Motion Limited ("RIM")

2.   Securities Sought:

     RIM may purchase from time to time, up to 9,500,000 of its issued common
shares (the "Shares") (being up to 5% of its outstanding Shares as at October
11, 2005) as hereinafter provided (the "Share Purchase Program").

3.   Time Period:

     The Share Purchase Program will commence on or about October 17, 2005 and
will terminate on October 17, 2006.

4.   Method of Acquisition:

     All purchases of Shares will be made only through the facilities of the
Nasdaq National Market and payment thereof will be made by RIM in accordance
with the by-laws and rules of the Nasdaq National Market and United States
federal securities laws. No purchases of Shares by RIM will be made through the
facilities of The Toronto Stock Exchange.

5.   Consideration Offered:

     The price which RIM will pay for any Shares acquired by RIM through the
facilities of NASDAQ will be the prevailing market price of the Shares at the
time of acquisition. Purchase and payment for any Shares purchased by RIM
through the facilities of NASDAQ will be made by RIM in accordance with the
rules and regulations of NASDAQ and applicable law.

     RIM and any vendor of Shares will be required to pay commission to their
respective brokers with respect to the purchase and sale of Shares through
NASDAQ at such rates as are from time to time in effect.

     This Notice of Intention should not be regarded as a solicitation or
recommendation to shareholders to sell or retain any Shares nor should it be
regarded as an undertaking to buy any Shares at any particular price.

6.   Payment for Securities:

     Payment for any Shares purchased will be made in accordance with customary
clearing and settlement procedures of NASDAQ.

7.   Reasons for Bid:

     The Board of Directors of RIM believes that the proposed purchase of up to
9,500,000 Shares is in the best interests of RIM from time to time and that
such purchases constitute a desirable use of RIM's funds.

<PAGE>

8.   Acceptance of Bid:

     Except as described below, none of the directors or senior officers of RIM
and, to the best of the knowledge, information and belief of RIM (after
reasonable inquiry), any associate of a director or senior officer of RIM, any
person or company holding 10% or more of the Shares of RIM or any person or
company acting jointly or in concert with RIM, intends to sell Shares or any
other class of shares to RIM under the Share Purchase Program. It is possible,
however, that sales by such persons may occur as a result of personal
circumstances or decisions or in order to fund the exercise price of the
options or for such other reasons as such person deems appropriate in each case
unrelated to the existence of the Share Purchase Program.

     RIM does not have any contract, arrangement or understanding, formal or
informal, with any holder of Shares with respect to its proposed purchase of
Shares under the Share Purchase Program.

9.   Benefits from Bid:

     Not applicable.

10.  Material Changes in the Affairs of Issuer:

     There are no previously undisclosed material changes or plans or proposals
for material changes in the affairs of the Company.
