                 ========          ======= 

Domestic  revenues and operating income  increased  compared with last year
primarily  due  to  acquisitions   in  the  automotive   businesses  and  market
penetration gains with fasteners and components in the U.S.  automotive markets.
Increased demand for construction products as a result of strong residential and
commercial  construction markets also contributed to the revenue growth. Product
line simplification in the welding operations resulted in a decrease in revenues
versus last year which  moderated the total  domestic  revenue  growth.  Margins
increased as a result of improved  operating  efficiencies in the automotive and
industrial components  businesses,  new products in the construction  operations
and cost reductions in the welding group.

Internationally,  revenue  gains in the  European  automotive  markets were
offset by the  effect of  foreign  currency  fluctuations  and  declines  in the
construction  markets,   which  remained  soft.  Operating  income  and  margins
increased  as  a  result  of  a  reduced  cost  structure  in  the  construction
operations.



INDUSTRIAL SYSTEMS AND CONSUMABLES SEGMENT

Businesses in this segment manufacture longer lead-time systems and related
consumables  for  consumer  and  industrial  packaging;  marking,  labeling  and
identification  systems;  industrial  spray coating  equipment and systems;  and
quality  assurance  equipment and systems.  The largest  markets  served by this
segment are general industrial, food and beverage, and industrial capital goods.

                =======         =======

Domestic revenue growth in the finishing  systems,  consumer  packaging and
Signode  businesses was offset by lower demand in the general industrial markets
for quality  measurement  equipment and a divestiture in the specialty packaging
operations.  Operating  income  and  margins  increased  largely  because of new
products for the consumer  packaging and finishing systems operations along with
improved manufacturing processes at Signode.

International  revenues increased  primarily as a result of acquisitions in
the Signode packaging operations, partially offset by lower revenues as a result
of foreign currency fluctuations and reduced revenues related to divestitures in
the European specialty packaging  businesses.  Operating income increased due to
successful cost reductions at the Signode and specialty packaging operations and
due to acquisitions. The sale of under-performing specialty packaging operations
along with aggressive cost reductions at the Signode and finishing systems units
led to the increase in margins.



LEASING AND INVESTMENTS SEGMENT

The Company has historically  had strong cash flows from its  manufacturing
operations.  Although most of this cash has been reinvested in the manufacturing
businesses  through  investments  in  capital  equipment,  acquisitions  and new
products,  some of the excess cash has been used to make financial  investments.
These  investments  primarily  include  leveraged and direct financing leases of
equipment,  mortgage-related investments, investments in properties and property
developments, and affordable housing investments.

Operating
income            $ 8,470   $ 6,352
                  =======   ======= 


Revenues and operating  income  increased  primarily due to the  commercial
mortgage transaction entered into at year-end 1996.

OPERATING EXPENSES

Cost of revenues as a  percentage  of  revenues  decreased  to 65.6% in the
first three months of 1997 versus  66.5% in the first three months of 1996,  due
to increased  sales  volume  coupled with lower  manufacturing  costs.  Selling,
administrative,  and research  and  development  expenses  decreased to 17.5% of
revenues  in the first  three  months of 1997  versus  18.6% in the first  three
months  of  1996,  primarily  due  to  expense  reductions  as  a  result  of  a
Company-wide objective to reduce administrative costs.

INTEREST EXPENSE

Interest  expense  decreased  to $6.0  million in the first three months of
1997 from $6.8  million  in the first  three  months of 1996,  primarily  due to
decreased commercial paper borrowings.

OTHER INCOME

Other  income  increased to $3.6 million for the first three months of 1997
from $2.1 million in 1996. This increase is primarily due to higher gains on the
sale of operations in 1997 and debt prepayment  costs in 1996,  partially offset
by losses on sale of fixed assets in 1997.

NET INCOME

Net income of $123.3 million ($0.99 per share) in the first three months of
1997 was 24.8%  higher than the 1996 first  quarter net income of $98.8  million
($0.81 per share).



FOREIGN CURRENCY

The  strengthening  of the U.S. dollar against  foreign  currencies in 1997
decreased  operating  revenues by  approximately  $15 million.  Foreign currency
fluctuations  had no material  impact on  earnings in the first  quarter of 1997
versus 1996.

Net working  capital at March 31, 1997 and December 31, 1996 is  summarized

The decrease in short-term debt was due to a reduction in commercial  paper
borrowings  during  the  first  quarter  of 1997 as a result  of  proceeds  from
divestitures.
