The potential winner(s) will be notified by email. If a potential winner does not respond to the notification attempt within five (5) days from the first notification attempt, then such potential winner will be disqualified and an alternate potential winner will be selected from among all eligible entries received based on the Competition’s judging criteria.

In the event that the Submission demonstrates non-compliance with these Competition Rules, Competition Sponsor may at its discretion take either of the following actions: (i) disqualify the Submission(s); or (ii) require the potential winner to remediate within one week after notice all issues identified in the Submission(s) (including, without limitation, the resolution of license conflicts, the fulfillment of all obligations required by software licenses, and the removal of any software that violates the software restrictions).
