Dear @ Joycebab,
thank you for addressing this question here in the community.
If the papers stated that you can return after 10 months passing, you have only one option to ask the Embassy of Holland in your country for an exception due to the business you have to attend, however they might ask for all the proof about the meeting you have in Holland.
I hope I could help you, if you ahve further questions please do not hesitate to use the platform.
Best regards,
Nilab
