Just be open and negotiate in good faith, or you'll cock up your potential acquisition. No demanding weird terms - it's only a 7 figure transaction. Running up their legal bill and being a pain in the ass will only hurt you. If you've got a reasonable worry that revealing a particular bit of information will materially damage your business should the negotiations fail, this you can initially withhold, with an explanation that it's sensitive and you'd like to wait until things are further along. But the vast bulk of the information request should be fine, and if you want to sell, you should provide it.
