If any of the Shipping Information initially requested by Brii Bio comes into VBI’s possession after the initial [**] ([**])-day period, VBI shall promptly, and in any case, within [**] ([**]) business days of receipt, deliver such Shipping Information to Brii Bio.

Promptly after obtaining such consent, VBI shall provide written notice and a copy of the executed Ferring Consent Letter to Brii Bio, and the date Brii Bio receives both such notice and such copy of the executed Ferring Consent Letter shall be the “Consent Delivery Date”.
