non interference with current and prospective clients

I am currently working for company A with whom I have signed agreement which says something like this: ...the Employee shall not, without written permission from xxx, undertake to interfere with xxxs' relationship with any restricted client or restricted prospective client by: - soliciting client or prospective client to provide competitive services - referring client or prospective clients to other person or entity providing competitive product or service - assisting any other person or entity in doing any of the foregoing... ... Now, I got job offer from another Company for similar job responsibility which is a consulting position, and this position also requires pre-sales engagement with the customer. The type of customers acquired by both of these companies has some overlap. Is there any problem for me to accept position with Company B ? Any possibility to avoid any problem while accepting offer from the new company ?
