`
`Dear Louis and Shaun,
`
`1. Please find attached the sealed version of the Complaint. It was filed under seal prophylactically in the event
`that you contend that it discloses Formycon confidential information. It does not disclose Regeneron confidential
`information.

`
`2. Given the passing of time, we are working on a revised schedule proposal. We have given further thought to
`your request to have less restriction on early invalidity arguments, and our revised proposal will reflect that.
`
`Thanks,
`
`Tom
