Signatures transmitted electronically or by facsimile shall have the same effect as original signatures. (14) In the event that there is any dispute over the interpretation of any terms of this settlement agreement, all parties, collectively, shall be considered the drafting party and any rule of construction to the effect that ambiguities are to be resolved against the drafting party shall be inapplicable.
