Ann: Sayona & Piedmont Formally Approve NAL Restart, page-43

"This offtake agreement will remain in place until the commencement of operation of a lithium
conversion plant in Québec. At this point, spodumene concentrate produced from NAL will be
preferentially delivered to that chemical plant upon the start of production. Any remaining concentrate
not required by the conversion plant will be delivered to Piedmont."

Conditions
If Sayona and Piedmont agree to jointly develop and operate a lithium chemical plant,
including a restart of the lithium carbonate plant at North American Lithium or another
lithium chemical plant at a different location, then the partners agree that the order of
priority for production volume of spodumene concentrate from North American Lithium
will be:
1. Jointly‐owned lithium chemical plant
2. Piedmont volume under the offtake agreement
3. Third parties

I think Piedmont are always going to have their finger in this Pie, Once chemical plant is running offtake will no longer be in place though you can almost guarantee Piedmont will own a share of the plant, they will also be taking all surplus spodumene from NAL
