purchased  in the tender  offer will be  acquired  in a  second-step  merger for
$152.00  per share in cash.  The  transaction  is subject to  customary  closing
conditions and regulatory approval.

Ten stockholders of Bryan Steam Corporation owning 55.6% of Bryan's  outstanding
common stock in the aggregate have irrevocably  agreed to tender their shares to
