I have read and re-read this sentence four times to try to figure out what is required here. This is my rewrite showing the first sentence.
He is obliged to notify the company immediately, if any of the situations described in this article exist.
"instructedto provide performance under this Agreement" this part of the sentence makes no sense to me. Perhaps it is because it is out of context.
Are you trying to say that "he" must do these things first before notifying the company??
