Upon receipt of your tender documentation, I will send you a confirmation of receipt stating whether your tender documentation is complete or incomplete. If you do not receive a confirmation of receipt from me, it is your responsibility to contact me at (978) 614-4374 to determine whether I received your election form and transmittal letter, and, if applicable, whether your tender documentation is complete or incomplete.
