Dear Al Guidicianni,
This offer has the interest of the Sundarian Federation, however we've not yet completed our calculations in to the amounts we would like to recieve, due to several issues with ambiguity in your offer.
Is this offer to be applied to deals made in the time-frame between now and

255, regards of the agreed upon term within the deal; or
Is this offer only valid for deals that last the aforementioned period?
Could you please elaborate on this matter so that we may start negotiations on the proper constraints.
Yours sincerely,
Thomas J.G. Pendra
