1 The “subject matter” identified for each witness is based on the parties’ positions in their respective transfer 

briefing and/or Rule 26 disclosures, and is provided for the convenience of the Court. For the avoidance of 

doubt, IBM does not concede to the purported relevance of those witnesses identified solely in VirtaMove’s 

transfer briefing and disclosures, nor does IBM concede to the subject matter VirtaMove identifies for the 

witnesses.
