PJ,
I guess I wasn't clear: I can sell photos to the exhibitors and they can use them for advertising anywhere they want. The issue is that I can't send a publication the formals -- to illustrate an article on the show for example -- until after they've been published in the ARK. My problem is that exhibitors know that the images will be published on the National website within a week and they know that the major awards will be published in ARK. So, what's their incentive to buy a print from me?

And, no, this year's contract cannot be renegotiated but I can assure you that next year's will be .
