Probably too late - but - the graphite will last for years - I've been doing some historical research recently - looking at documents 150 plus years old which have contemporary 
 pencil annotations.
The paper is probably the key thing - modern papers tend to be more acidic and prone to decay (high wood pulp - low linen content)  - invest in some archiving paper - and the document will last for decades or more.
