Trying to rephrase a paragraph with unusual grammar to get intended message across

Hi All,

Here is the phrase:
" The defendant expressly understands that his waiver is not predicated upon any promises, agreements, or understandings of any kind between party B and the defense in this case, and nothing herein shall be construed to preclude party B from proceeding against the defendant during or after the time period covered by this waiver. "

I need to amend it to say:
" The defendant expressly understands that his waiver is predicated only on the promise that Party B shall entertain plea offers, and that the trail will be set no earlier than May 5th but is otherwise not predicated upon any other promises, agreements, or understandings. It is only the terms set forth in this phrase that may preclude party B from proceeding against the defendant during or after the time period covered by this waiver. "

Through clever wordplay, strategic punctuation, and grammar, it must seem to a quick reviewer that the clause states that the trial shall take place no later than May 5th, but in fact states that it should take place no earlier to someone well versed in English grammar rules. Could I please have some help? Thanks,

Hello sabooakhter,
This sounds like legal language, regarding which, I'd always recommend consulting an attorney before presenting it within a contractual agreement. But if you're looking at least for a quick suggestion.

"The defendant expressly understands that his waiver is not predicated upon any other promises, agreements, or understandings except only on the promise that Party B shall entertain plea offers, and that the trial will be set no earlier than May 5th. It is only the terms set forth in this phrase thatupon these terms that may preclude party B from proceeding against the defendant during or after the time period covered by this waiver."

I needed something that modifies the trial set date, not the second sentence.
