(1)	The two reported transactions involved an amendment to the termination period of an outstanding option in order to provide that the term of the option shall extend until twenty-nine days after the earliest date upon which the option may be exercised without violating applicable securities laws (which earliest date is expected to be the date upon which Rambus Inc. is current in its SEC reporting obligations). This resulted in the deemed cancellation of the "old" option and the grant of a replacement option. The option was originally granted on February 12, 1997 and provided for the option to vest in full on August 12, 1997.
