exit notice on bnbg for balto

I don't think there is a specific form for the Exit Notice.

Here are the Exit Notice provisions from the prospectus and its the second one under 4.2 thats relevent and we'd need to wait for the trigger event notice from BNB:

Holder exit rights
4.1 Reset Date or the Maturity Date
A Holder may request Exchange of all of their BBSN (or, in relation to a Reset Date, some of their BBSN, but
only if after such Exchange, the Holder will hold at least 100 BBSN) by providing an Exit Notice to the Issuer
requesting Exchange at least 35 Business Days (but no more than 50 Business Days) prior to each of:
(a) any Reset Date; and
(b) the Maturity Date.


4.2 Trigger Event or Change in Control Event
(a) The Issuer must give notice to Holders that a Trigger Event or a Change in Control Event (as applicable)
has occurred as soon as reasonably practicable after it becomes aware of such occurrence.
(b) A Holder may request Exchange or Repayment of all (but not some only) of their BBSN by providing an Exit
Notice to the Issuer after the occurrence of a Trigger Event — no later than 15 Business Days after the date of
the notice issued by the Issuer under clause 4.2(a).
(c) A Holder may request Exchange of all (but not some only) of their BBSN by providing an Exit Notice to the
Issuer after the occurrence of a Change in Control Event — no later than 15 Business Days after the date of
the notice issued by the Issuer under clause 4.2(a).
