NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 -- Financial Statements

The interim information furnished in these financial statements is unaudited.

The  Registrant  and its  subsidiaries  are referred to herein on a consolidated
basis as the Company.

Note 2 -- Extraordinary Loss

In the first quarter of 1998, the Company repurchased $24.0 million in principal
amount of its Senior  Subordinated  Debentures.  Deferred debt issuance costs of
$.3  million  related  to  the  repurchased  Debentures  were  written  off.  An
extraordinary loss of $.2 million related to this repurchase,  net of applicable
income taxes, was reported in the quarter.

In the first quarter of 1997, the Company repurchased $14.5 million in principal
amount of its Senior Notes at a premium of $1.5 million.  In addition,  deferred
debt issuance costs of $.3 million related to the repurchased Notes were written
off. An extraordinary  loss of $1.5 million related to this  repurchase,  net of
applicable income taxes, was reported in the quarter.

Note 3 -- Discontinued Operations

In the first quarter of 1997, the Company received  additional proceeds from the
sale in 1996 of its Packaging  businesses  resulting in income from discontinued
operations of $1.5 million, net of applicable income taxes.

Note 4 -- Computation of Common Share Data

The weighted  average number of common shares  outstanding used to compute basic
per share amounts was 23,175,000 and 23,152,000 for the second  quarters of 1998
and 1997, respectively. For the first six months, the weighted average number of
common shares was  23,191,000  for 1998 and 23,147,000 for 1997. For diluted per
share amounts, the weighted average number of common shares outstanding used was
33,485,000  and   32,458,000   for  the  second   quarters  of  1998  and  1997,
respectively.  For the first six months,  the weighted  average number of common
shares  was  33,545,000  for 1998 and  32,385,000  for 1997.  The  effect of the
dilutive Convertible  Exchangeable  Preferred Stock was to increase the weighted
average number of shares outstanding used in the computation of diluted earnings
per share by 10,025,000 and 9,174,000  shares in the second quarters of 1998 and
1997,  respectively.  For the  first six  months,  the  effect  of the  dilutive
Convertible  Exchangeable  Preferred Stock was to increase the weighted  average
number of shares by 10,020,000 and 9,172,000,  respectively. Stock options added
285,000  common shares in the second quarter and 334,000 in the first six months
of 1998 and 132,000 in the second  quarter and 66,000 in the first six months of
1997.

Note 5 -- Income Taxes

The effective tax rate on income from continuing  operations was 44.6% and 63.5%
for the second quarter of 1998 and 1997, respectively. For the first six months,
the effective  rate was 42.5% for 1998 and 63.1% for 1997. In 1998,  the Company
provided  for U.S.  federal  and state  income  taxes as well as for  additional
amounts related to open U.S. federal tax return years of 1982 through 1990.

In 1997,  because most of the Company's interest expense was borne in the United
States at the parent company level,  the Company had substantial  taxable income
in foreign and state  jurisdictions.  Taxes due to foreign  authorities were not
offset by U.S. federal income tax benefits.

Note 6 -- Comprehensive Income

In June of 1997, the Financial  Accounting  Standards Board issued  Statement of
Financial  Accounting Standards No. 130, "Reporting  Comprehensive  Income". The
Statement,  which the Company adopted in the first quarter of 1998,  establishes
standards for reporting and displaying  comprehensive  income and its components
in a full set of general-purpose financial statements. Where applicable, earlier
periods  have  been  restated  to  conform  to the  standards  set  forth in the
Statement. The Company's Comprehensive Income consists of net income and foreign
currency translation  adjustments which are presented before tax.  Comprehensive
Income in the second  quarter and first six months of 1997 includes $1.0 million
and $3.3 million,  respectively, of foreign currency exchange losses relating to
the foreign Handling  businesses sold in the fourth quarter of 1997. The Company
does  not  provide  for  U.S.  income  taxes  on  foreign  currency  translation
adjustments because it does not provide for such taxes on undistributed earnings
of foreign subsidiaries, some of which were subject to statutory restrictions on
distribution.

Note 7 -- Acquisitions

In the first quarter of 1997, the Company acquired the assets of ARC Metals Inc.
for $5.0 million in cash and a promissory note in the amount of $2.8 million.

Note 8 -- Environmental Matters

In connection with the reorganization of the old Interlake, Inc. (now Acme Steel
Company  ("Acme")) in 1986, the Company,  then  newly-formed,  indemnified  Acme
against certain environmental  liabilities relating to properties which had been
shut down or  disposed of by Acme's  iron and steel  division  prior to the 1986
reorganization.  After  taking a  nonoperating  charge of $10.5  million  in the
fourth  quarter  of 1997  and  $1.3  million  in 1998 as  discussed  below,  the
Company's  reserves for  environmental  liabilities  totaled $11.0 million as of
June 28,  1998,  most of which  relates  to the Acme  indemnification.  Of these
amounts, $4.8 million was classified as a current liability as of June 28, 1998.

The nonoperating charges of $10.5 million in the fourth quarter of 1997 and $1.3
million in 1998 related to anticipated liabilities for environmental matters. Of
these  amounts,  $8.9 million  related to  anticipated  costs of  remediation of
certain  underwater  sediments at the  Superfund  site on the St. Louis River in
Duluth,  Minnesota (the "Duluth Site"). The Company's  liability with respect to
the Duluth Site arises out of the Acme indemnification  discussed above. In June
1998, the Company submitted to the Minnesota Pollution Control Agency ("MPCA") a
Remedial  Investigation/Feasibility  Study  (RI/FS)  recommending  a remedy  for
certain  underwater  sediments at the Duluth Site and examining  other potential
remedies.  The Company believes that, if selected,  the recommended remedy could
be implemented at a cost approximating the Company's  remaining reserves for the
Duluth  Site.  Any of the other  alternatives  reviewed  in the RI/FS would cost
more, potentially exceeding the cost of the Company's recommended alternative by
$5 to $25 million.  The MPCA,  together  with other  governmental  agencies,  is
presently  reviewing the RI/FS, and is expected to indicate its preferred remedy
in August or September 1998. Although the MPCA has preliminarily  indicated that
it does not  favor  the  Company's  recommended  alternative,  the  parties  are
continuing to discuss potential remediation alternatives.

The  Company  believes  that  based on its  current  estimate  of its  potential
environmental  liabilities,  including all contingent liabilities,  individually
and in the  aggregate,  asserted and  unasserted,  that subject to the remaining
uncertainty  with  respect  to the Duluth  Site  discussed  above,  the costs of
environmental  matters  have been fully  provided  for or are unlikely to have a
material  adverse  effect on the  Company's  business,  results  of  operations,
liquidity or  financial  condition.  In arriving at its current  estimate of its
potential environmental  liabilities,  the Company has relied upon the estimates
and analyses of its environmental consultants and legal advisors, as well as its
own   evaluation,   and  has   considered:   the  probable  scope  and  cost  of
investigations and remediations for which the Company expects to have liability;
the  likelihood  of the Company  being found  liable for the claims  asserted or
threatened against it; and the risk of other responsible  parties not being able
to meet their obligations with respect to clean-ups.  The Company's estimate has
not been discounted to reflect the time-value of money, although a significant

                                        7





delay in  implementation of certain of the remedies thought to be probable could
result in cost estimates increasing due to inflation.

The Company's  current estimates of its potential  environmental  liabilities do
not reflect any anticipated  recoveries from third parties. The Company believes
that the  successors to certain coal tar processors at the Duluth Site (the "tar
companies"), who have been named as additional responsible parties for a portion
of the underwater  sediments by the MPCA, are the cause of a significant portion
of the underwater  contamination  at the site. The tar companies have maintained
that their contributions were minimal.  In addition,  the Company has pending an
action  seeking a  declaratory  judgment  and  recoveries  from  insurers  under
policies  covering various periods during the 1960's,  1970's and 1980's. In the
first half of 1998,  the  Company's  net income  benefitted  by $1.6  million in
insurance recoveries,  net of increases in reserves,  all relating to historical
environmental issues.

The  Company's  current   expectation  is  that  cash  outlays  related  to  its
outstanding  reserves for  environmental  matters will be made during the period
from 1998 through 2000 with the most significant  expenditures  expected in 1999
and 2000.

Note 9 -- Commitments and Contingencies

The Company is engaged in certain  routine  litigation  arising in the  ordinary
course  of  business.  Based  upon  its  evaluation  of  available  information,
management does not believe that any such matters are likely, individually or in
the aggregate,  to have a material  adverse effect upon the Company's  business,
results of operations, liquidity or financial condition.

On March  10,  1995,  SC  Holdings,  Inc.,  a  subsidiary  of  Waste  Management
International  plc ("SC Holdings"),  filed a complaint in federal district court
in Trenton, New Jersey, against Hoeganaes Corporation,  an Interlake subsidiary,
and numerous  other  defendants,  seeking to recover  amounts  expended or to be
expended in the remediation of the Cinnaminson Groundwater Contamination Site in
Burlington  County,  New Jersey. SC Holdings claims to have spent  approximately
$10.0 million in investigation and remediation, and estimates the total costs of
investigation and remediation to be approximately  $60.0 million.  The site is a
broadly- defined  Superfund site which  encompasses a landfill formerly operated
by SC Holdings and may also include the groundwater  under Hoeganaes'  Riverton,
New Jersey facility.

Hoeganaes  may have  shipped  certain  materials  to the  landfill.  SC Holdings
alleges that Hoeganaes has liability as both an owner/operator  and a generator.
On June 1, 1998, the court granted  Hoeganaes  Corporation's  motion for partial
summary judgment,  dismissing all claims related to generator liability. Earlier
in 1998, as part of a non-binding  mediation process, the mediator had concluded
that  Hoeganaes  Corporation  ought not to be liable  as an  owner/operator.  SC
Holdings  and  Hoeganaes   Corporation  are  presently  engaged  in  discussions
regarding the settlement of the matter.

ITEM 2.      MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
             FINANCIAL CONDITION

Results of Operations


Interlake's foreign Handling businesses were sold in the fourth quarter of 1997.
The results of their  operations  and cash flow are  included  in the  Company's
consolidated  statement of operations and  consolidated  statement of cash flows
for the 1997 periods, but were excluded for the 1998 periods.

Second Quarter 1998 Compared with Second Quarter 1997

Net sales were $134.5  million in the quarter  ended June 28, 1998 compared with
sales of $185.8 million in the prior year period.  Net sales without the results
of the sold foreign Handling businesses were $121.4 million in the 1997 quarter.
Sales in the Engineered  Materials segment increased 12% to $86.8 million in the
1998 quarter due to increased  unit volume at Special  Materials  and  increased
shipments of  fabricated  components  and  additional  blade repair  activity at
Aerospace  Components.  Handling  segment sales declined 56% to $47.7 million in
the 1998 quarter reflecting the sale of the foreign Handling  businesses.  Sales
at the  remaining  Handling  business in North  America  increased 7% reflecting
increased  volume.  Operating  profit  was  $15.5  million  in the 1998  quarter
compared to $16.0 million in the prior year period. Excluding the results of the
sold foreign Handling businesses, operating profit in the second quarter of 1997
was $13.3 million.  Interest  expense was $9.2 million compared to $11.4 million
in the 1997 quarter  reflecting  lower  levels of  borrowing  after the required
application of proceeds from the sale of the foreign  Handling  businesses.  Net
income of $2.6 million in the second  quarter of 1998 compared to $.7 million in
the 1997 quarter.

Segment Results

The Company's  businesses are organized into two segments:  Engineered Materials
and Handling.  Businesses in Engineered Materials are Special Materials (ferrous
metal  powders)  and  Aerospace   Components   (precision   aerospace  component
fabrication  and  aviation  repair).  The  Handling  segment  includes the North
American  operations  in the  1998  periods,  while  the sold  foreign  Handling
businesses in Europe and Asia Pacific were also included in 1997.

                                        9





Engineered Materials

Second quarter sales in the Engineered  Materials segment increased 12% to $86.8
million, due to higher fabrication  shipments and improved blade repair activity
at Aerospace  Components and increased metal powder sales at Special  Materials.
Operating  profit for the segment  increased 1% in the 1998 quarter  compared to
the 1997 period.

Special Materials' metal powder sales increased 2% compared with the same period
last year due to  increased  volume  which  was  minimally  affected  by an auto
industry strike in the current quarter. Earnings declined 2% as increased volume
and improved  sales of higher  margin  products  were more than offset by higher
material,  freight and  manufacturing  costs and increased  depreciation  due to
plant expansion.

Aerospace  Components'  sales  increased 32% from the 1997 second quarter due to
increased  fabrication  shipments on key commercial and military engine programs
and improved  blade repair  activity.  Earnings  for the quarter  increased  11%
reflecting  increased volume and improved  manufacturing  performance which were
partially offset by increased  administrative costs to respond to growth demands
as  well  as  relatively  higher  increases  in  indirect  labor,   repairs  and
maintenance and production supplies for fabricated components.

Order  backlogs in this  segment  were $174.9  million at the end of the quarter
compared to $176.7  million at the end of the 1997  period.  Special  Materials'
backlog,  which is  generally  short term in  nature,  declined  12%.  Aerospace
Components' backlog increased 2% reflecting continued strong order intake.

The labor strike at General Motors which occurred late in the second quarter has
not had a material  effect on the  results of  operations  of Special  Materials
through the end of the quarter.  However, the strike is ongoing, and the Company
cannot predict when the parties will reach a resolution of the work stoppage. In
the event the strike is prolonged,  the results for Special  Materials  could be
adversely affected in future periods.

Handling

Sales in the  Handling  segment for the second  quarter  decreased  56% to $47.7
million,  compared with $108.4  million in the 1997 quarter,  due to the sale of
the foreign  Handling  businesses.  North American  Handling sales increased 7%,
principally from additional volume.

Handling segment  operating  profit declined 31% to $1.7 million  reflecting the
disposition  of  the  foreign  Handling  businesses.  Handling  North  America's
earnings  increased 119% over 1997 reflecting the benefit of favorable  pricing,
increased volume,  favorable operating variances and lower  administrative costs
which  were  partially  offset by the  effect of  higher  sales of lower  margin
products.

Order  backlogs  in this  segment  were  $22.2  million at the end of the second
quarter  compared to $121.7  million in 1997 which  included  the backlog of the
sold foreign Handling  businesses.  The order backlog at the remaining  Handling
business in North America  decreased 31% from order backlogs of $32.4 million in
the prior year because of reduced order intake in the 1998 second quarter.

First Half 1998 Compared with First Half 1997

For the first six  months of 1998,  net sales of $268.5  million  were down 25%,
compared  with net sales of $356.0  million in the 1997  period.  Net sales were
$236.0  million in the first six months of 1997  without the results of the sold
foreign Handling businesses. Sales in the Engineered Materials segment increased
14% to $170.6  million,  due to higher  unit  volume at  Special  Materials  and
increased  shipments of fabricated  components at Aerospace  Components.  In the
Handling  segment,  sales  declined 52% to $97.9 million in 1998  reflecting the
sale  of the  foreign  Handling  businesses.  Sales  at the  remaining  Handling
business in North America  increased 13%  principally  due to increased  volume.
Operating  profit was $29.2  million in 1998  compared with $29.9 million in the
prior  year  period.   Excluding  the  results  of  the  sold  foreign  Handling
businesses,  operating profit in the first half of 1997 was $26.1 million.  1998
non-operating  income in the first half  includes a $1.6  million  benefit  from
insurance recoveries,  net of increases in reserves,  all relating to historical
environmental  issues.  Interest  expense  was $18.9  million  compared to $23.0
million in the first half of 1997 reflecting lower levels of indebtedness  after
the  required  application  of proceeds  from the sale of the  foreign  Handling
businesses.  Net  income  of  $5.3  million  for the  1998  period  includes  an
extraordinary loss of $.2 million, net of tax, related to the early retirement

                                       10





of a portion of the Company's  debt. Net income of $.8 million in the first half
of 1997  included  income from  discontinued  operations  of $1.5 million and an
extraordinary loss of $1.5 million related to early debt retirement.

Engineered Materials

First  half  1998  sales  in the  Engineered  Materials  segment  increased  14%
reflecting increased unit volume at Special Materials and increased  fabrication
shipments and improved blade repair activity at Aerospace Components.  Operating
profit for the segment increased 2%.

Special  Materials' metal powder sales increased 3% due to increased unit volume
in the first half of 1998 as compared to the 1997 period.  Earnings in the first
half of 1998  decreased  1% from 1997 as higher  volume  and  improved  sales of
higher  margin  products were more than offset by higher  material,  freight and
manufacturing costs and increased depreciation due to plant expansion.

Aerospace  Components' sales increased 35% compared with the same period in 1997
reflecting  increased  fabrication  shipments  on key  commercial  and  military
programs as well as improved  blade  repair  activity.  Earnings  for the period
increased  14%  reflecting  increased  volume  which  was  partially  offset  by
additional  administrative  costs to respond  to growth  demands  and  increased
operating costs.

Handling

Sales in the Handling  segment in the first half declined 52% to $97.9  million,
compared  with  $205.8  million  in the 1997  first  half due to the sale of the
foreign Handling businesses.  North American Handling sales increased 13% due to
increased shipments in the 1998 period.

Operating profit decreased 33% to $3.1 million reflecting the disposition of the
foreign  units.  Handling  North  America's  earnings  increased 34% in the 1998
period as the effect of the  increased  volume,  a favorable  settlement  with a
supplier  and  favorable  operating  variances  were  partially  offset by sales
pricing  weakness on 1997  bookings  shipped in 1998,  increased  sales of lower
margin products and favorable accrual adjustments  recorded in the first quarter
of 1997.

Nonoperating Items

As  discussed  in Note 8 of  Notes to  Consolidated  Financial  Statements,  the
Company  continues to attempt to resolve  certain  anticipated  liabilities  for
environmental   matters.  If  the  Company's   recommended  remedy  for  certain
underwater  sediments at the Duluth Site is accepted,  the Company believes that
the costs of environmental  matters have been fully provided for or are unlikely
to  have a  material  adverse  effect  on the  Company's  business,  results  of
operations,  liquidity or financial  condition.  However,  there is no assurance
that  the  Company's  preferred  remedy  will  be  recommended  by the  relevant
government agencies.



                                       11



Discontinued Operations

In the first  quarter of 1997,  the  Company  received  additional  proceeds  in
respect  of the  October  1996 sale of its  Packaging  businesses.  Income  from
discontinued  operations of $1.5 million,  net of income taxes,  was recorded to
reflect the adjustment to the gain.

Extraordinary Loss

During the first quarter of 1998, the Company recorded an extraordinary  loss of
$.2 million,  net of income  taxes,  for the write-off of deferred debt issuance
costs  related to the  repurchase  and early  retirement of $24.0 million of the
Company's Senior Subordinated Debentures.

During the first quarter of 1997, the Company recorded an extraordinary  loss of
$1.5 million, net of income taxes, for the premium incurred and the write-off of
deferred debt issuance costs related to the  repurchase and early  retirement of
$14.5 million of the Company's Senior Notes.

Financial Condition

The Company's  total debt was $294.3 million at the end of the second quarter of
1998, down $29.4 million from the 1997 year-end.  Cash and  equivalents  totaled
$30.4 million at the end of the quarter,  compared with $84.5 million at the end
of 1997  reflecting  the  repurchase  of $24.0  million  of Senior  Subordinated
Debentures,  the $4.0 million payoff of the ESOP note, increased working capital
requirements and capital expenditures.  Capital expenditures of $25.3 million in
the first half of 1998 compared with $9.9 million in 1997,  reflecting increased
spending for expansion,  particularly in the Engineered  Materials segment.  The
Company  anticipates  that 1998 capital  spending  will be  approximately  $55.0
million.

The Company has received  commitments  for the  replacement of its existing bank
credit  facilities with a two-year $75 million  revolving  credit  facility.  It
expects to finalize  the  documentation  of the new  facility by the end of July
1998.  Were it unable to finalize the new  facility,  and its current bank group
did not  agree to extend  the  existing  facility,  the  Company  would not have
adequate  liquidity  to fund its  operations  and  carry  out its  1998  capital
spending plan.

The Company has  substantial  debt repayment  requirements in the years 2001 and
2002.

Hedging Activities

On June 15,  1998,  the  Financial  Accounting  Standards  Board  (FASB)  issued
Statement of Financial  Accounting Standards No. 133, "Accounting for Derivative
Instruments  and Hedging  Activities"  (SFAS 133). SFAS 133 is effective for all
fiscal  quarters of all fiscal years beginning after June 15, 1999 (beginning of
fiscal  year  2000 for the  Company).  SFAS  133  requries  that all  derivative
instruments be recorded on the balance sheet at their fair value. Changes in the
