Dear AMP Institutional Shareowner:

     In talking with some institutions, a few issues have been raised which
we believe may require some clarification.

       . If  you tender  your shares  into  AlliedSignal's  $44.50
         offer  and  AlliedSignal   raises  its  offer,  you  will
         receive  the higher  offer  without  having to  re-tender
         your shares.

       . If  you tender your shares into AlliedSignal's  offer and
         a third  party  makes a higher  offer you will be free to
         withdraw your shares and accept the higher offer.

       . If  you tender your  shares and wish to withdraw  them at
         a   later   time   the   withdrawal   process   is   very
         straightforward  and a withdrawal can be effected  within
         hours.

       . Tendering  your  shares does not commit you to voting for
         AlliedSignal  on  the  consent  solicitation.  After  the
         initial  expiration of the tender  offer,  a consent form
         will be sent to you and at that  time you may vote in any
         manner you choose.

     Should you have questions on these issues or any other issues,  please
call Tom Ball, Ron Knox or Fred Marquardt at 1-800-662-5200.

Sincerely,

Morrow & Co., Inc.
Information Agent for AlliedSignal Inc.
