If your Pass offers a Referral program with Points, you can find what rewards there are by going to this page: http://app.leaderpass.com/referrals/redeem (your must be logged into your LeaderPass account to view this page)
The Redeem page allows you to trade your earned Points in for extended access to one of your available Passes — or even create Invites, which you can gift to others!
This page will also display how many Points you can earn based on how many people sign up through your Referral link. It will then show you how many Points are needed to unlock a new Invite or extend your own personal access.
