                                                         6





operations  meaningless.  The  effective  tax  rate on  income  from  continuing
operations  was  62.2% in the 1997  quarter.  For the  first  nine  months,  the
effective  rate was 31.9% for 1998 and 62.8%  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,  domestic  and foreign  subsidiaries  of the  Company  had  substantial
taxable  income while the parent  Company had a loss because it incurred most of
the  consolidated  interest  expense.  The  domestic  and  foreign  subsidiaries
incurred  state and  foreign  taxes,  respectively,  despite  the high levels of
consolidated interest expense.

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 third  quarter and first nine months of 1997 includes $1.3 million
and $4.6 million,  respectively, of foreign currency exchange losses relating to
the foreign Handling  businesses sold in the fourth quarter of 1997. The Company
has  not  provided  for  U.S.  income  taxes  on  foreign  currency  translation
adjustments because it has not provided 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.  On September 28, 1998, Acme and its affiliated  companies filed
for  protection  under  Chapter 11 of the United  States  Bankruptcy  Code.  The
Company has  retained  legal  counsel to advise it with respect to the effect of
this filing on the Company's indemnification obligation to Acme, but has not yet
come to any conclusion in this regard.

After taking  non-operating  charges related to  environmental  matters of $10.5
million in the fourth  quarter of 1997 and $1.3 million in 1998,  the  Company's
reserves for environmental liabilities totaled $10.3 million as of September 27,
1998, most of which relates to the Acme indemnification.  Of these amounts, $4.2
million was  classified  as a current  liability as of September  27, 1998.  The
anticipated  costs  of  remediation  of  certain  underwater  sediments  at  the
Superfund  site on the St. Louis River in Duluth,  Minnesota (the "Duluth Site")
represented  $8.9  million  of the  $11.8  million  of  charges.  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,

                                                         7





and is expected to indicate its preferred  remedy sometime in 1998. The MPCA has
preliminarily  indicated  that it  does  not  favor  the  Company's  recommended
alternative,  but it is still in the  process  of  receiving  input  from  other
governmental agencies.

The  Company   believes,   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
delay in  implementation of certain of the remedies thought to be probable could
result in cost estimates increasing due to inflation.  The Company's estimate of
its potential  environmental  liabilities also does not reflect the effects,  if
any, of the Acme bankruptcy discussed in Note 9 and above.

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 nine months 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.  If the Company  ultimately  determines  that  additional  charges are
necessary in connection with the Duluth Site, the Company  believes it is likely
that cash outlays would occur later.

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.

                                                         8





On September 28, 1998, Acme Steel Company ("Acme") and its affiliated  companies
filed for  protection  under  Chapter 11 of the United States  Bankruptcy  Code.
Prior to  1986,  Acme  was  known as  Interlake,  Inc.  In  connection  with the
reorganization  of  Acme  (the  old  Interlake)  in  1986,  the  Company,   then
newly-formed,  indemnified  Acme against  certain  environmental,  tax and other
liabilities.  In  addition,  at the  time  of  the  reorganization  Acme  became
obligated to the Company with respect to certain pollution control bonds assumed
at that  time by the  Company  but  pertaining  to  facilities  of  Acme.  As of
September  27,1998,  the  principal  amount of Acme's  obligation to the Company
related  to such  bonds was $5.5  million.  In the third  quarter,  the  Company
recorded  a  non-operating  charge of $4.4  million  for a  valuation  allowance
against this receivable to a level consistent with the post-filing trading range
of Acme's parent  corporation's  unsecured public debt. The Company has retained
legal counsel to advise it as to the other effects of the filing on the Company,
including  among others any effect upon the  Company's  obligation  to indemnify
Acme with respect to certain liabilities.

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

Results of Operations

Interlake's  foreign Handling businesses in Europe and Asia Pacific 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.

Third Quarter 1998 Compared with Third Quarter 1997

Net sales were $127.7  million in the quarter ended  September 27, 1998 compared
with sales of $195.5  million in the prior year  period.  Net sales  without the
sales of the sold foreign  Handling  businesses  were $119.6 million in the 1997
quarter.  Sales  in the  Engineered  Materials  segment  increased  11% to $81.9
million in the 1998 quarter due to increased shipments of fabricated  components
and additional blade repair activity at Aerospace  Components.  Sales at Special
Materials  were  comparable  to 1997 as the  strike at certain  General  Motors'
facilities  limited  volume  in the  current  quarter.  Handling  segment  sales
declined  62% to $45.8  million in the 1998 quarter  reflecting  the sale of the
foreign Handling  businesses.  Sales at the remaining Handling business in North
America  increased 1% over the 1997 quarter.  Operating profit was $13.3 million
in the 1998  quarter  compared  to  $14.1  million  in the  prior  year  period.
Excluding the results of the sold foreign Handling businesses,  operating profit
in the third  quarter of 1997 was $10.6  million.  As discussed  below under the
heading Non-operating Items,  non-operating expense in the third quarter of 1998
included a $4.4 million charge  relating to certain Acme  obligations.  Interest
expense  was  $9.2  million  compared  to  $11.3  million  in the  1997  quarter
reflecting lower levels of borrowing after the required  application of proceeds
from the sale of the foreign Handling  businesses.  The 1998 quarter's provision
for taxes  included a $2.0 million  reduction due to the  reconciliation  of the
1997  provision to the liability  determined in preparation of the returns filed
relating to taxes due on the 1997 sale of the Dexion  businesses.  Net income of
$.9 million in the 1998 quarter  included an  extraordinary  loss of $.2 million
related to the early  retirement of a portion of the Company's  debt. Net income
in the 1997 third  quarter was $.8 million  and  included  $.3 million of income
from discontinued operations.

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 only the North
American  operations  in the  1998  periods,  while  the sold  foreign  Handling
businesses were also included in 1997.

                                                         10





Engineered Materials

Third quarter sales in the Engineered  Materials  segment increased 11% to $81.9
million, due to higher fabrication  shipments and improved blade repair activity
at Aerospace  Components,  while powder  metal sales at Special  Materials  were
comparable to 1997.  Operating  profit for the segment  increased 7% in the 1998
quarter compared to the 1997 period.

Special  Materials' metal powder sales were comparable with the same period last
year as an auto  industry  strike  during  the  quarter  limited  volume to 1997
levels.  Earnings  declined 5% as higher  depreciation  and increased  personnel
costs  relating  to the startup of the  expansion  facilities  at the  Gallatin,
Tennessee  plant,  higher  annual  maintenance  costs,   unfavorable   inventory
valuation  adjustments and 1997 insurance proceeds were only partially offset by
increased  sales of higher  margin  products and lower scrap costs.  The company
expects the  expanded  facility at  Gallatin to be in full  production  by early
1999.  Earnings in the third  quarter of 1998 were  reduced  approximately  $1.0
million due to lost volume from the labor strike at General Motors.

Aerospace  Components'  sales  increased  29% from the 1997 third quarter due to
increased  fabrication  shipments on key commercial and military engine programs
as well as higher blade repair activity.  Earnings for the quarter increased 48%
over the 1997 quarter as increased volume,  improved  manufacturing  performance
and  favorable   operating   variances  resulting  from  improved  direct  labor
utilization were partially offset by administrative  costs related to the volume
increase and litigation expense.

Order  backlogs in this  segment  were $220.2  million at the end of the quarter
compared to $178.6  million at the end of the 1997  period.  Special  Materials'
backlog,  which is  generally  short  term in  nature,  declined  8%.  Aerospace
Components' backlog increased 30% to a record level, reflecting continued strong
order intake on key engine programs.

Handling

Sales in the Handling  segment  declined  62% to $45.8  million,  compared  with
$121.4  million in the 1997  quarter,  due to the sale of the  foreign  Handling
businesses.  North  American  Handling  sales  increased 1% as improved  selling
prices were partially offset by reduced volume.

Handling segment  operating profit decreased 54% to $1.6 million  reflecting the
disposition of the foreign units.  Handling North America's  earnings  increased
258% over 1997  reflecting  the  benefits  of  favorable  sales  pricing,  lower
material costs and reduced factory administration which were partially offset by
lower volume.

Order  backlogs  in this  segment  were  $24.8  million  at the end of the third
quarter  compared to $125.2  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 37% from the order backlogs of $39.1 million
in the prior year because of reduced order intake;  however,  order rates during
1998 have remained strong.

Nine Months 1998 Compared with Nine Months 1997

For the first nine months of 1998,  net sales of $396.2  million  were down 28%,
compared  with net sales of $551.5  million in the 1997  period.  Net sales were
$356.2  million in the first nine months of 1997 without the results of the sold
foreign Handling businesses. Sales in the Engineered Materials segment increased
13% to $252.5 million,  due to increased  volume at Special  Materials which was
limited  by the strike at  certain  General  Motors'  facilities  and  increased
shipments of  fabricated  components  and  additional  blade repair  activity at
Aerospace  Components.  In the Handling  segment,  sales  declined 56% to $143.7
million in 1998 reflecting the sale of the foreign Handling businesses. Sales at
the remaining Handling business in North America increased 9% principally due to
increased volume. Operating profit was $42.5 million in 1998 compared with

                                                         11





$44.0  million  in the prior  year  period.  Excluding  the  results of the sold
foreign Handling  businesses,  operating profit in the first nine months of 1997
was $37.8 million.  As discussed  below under the heading  Non-operating  Items,
non-operating  (income)  expense in 1998 included a $4.4 million charge relating
to certain Acme  obligations.  This charge is partially offset by a $1.6 million
benefit from insurance recoveries, net of increases in reserves, all relating to
historical  environmental issues. Interest expense was $28.1 million compared to
$34.3  million  in the first  nine  months of 1997  reflecting  lower  levels of
indebtedness  after the required  application  of proceeds  from the sale of the
foreign Handling businesses. The provision for taxes in the first nine months of
1998  included a $2.0 million  reduction due to the  reconciliation  of the 1997
provision  to the  liability  determined  in  preparation  of the returns  filed
related  to taxes due on the 1997 sale of the Dexion  businesses.  Net income of
$6.2 million for the first nine months of 1998 includes an extraordinary loss of
$.5 million related to the early  retirement of a portion of the Company's debt.
Net income of $1.6  million in the 1997 period  included  income of $1.8 million
from  discontinued  operations and an extraordinary  loss of $1.5 million on the
early retirement of a portion of the Company's debt.

Engineered Materials

Notwithstanding  the  effects  of the labor  strike at certain  General  Motors'
facilities on volume at Special  Materials,  sales in the  Engineered  Materials
segment increased 13% to $252.5 million,  reflecting  increased volume primarily
due to increased  shipments  of  fabricated  components  and higher blade repair
activity at Aerospace Components. Operating profit for the segment increased 3%.

Special  Materials' metal powder sales increased 2% due to increased unit volume
in the first nine months of 1998 as compared to 1997.  Earnings  decreased 2% in
the  nine-month  period,   reflecting   increased  personnel  costs  and  higher
depreciation  relating to the startup of expansion  facilities  at the Gallatin,
Tennessee plant,  higher freight costs, higher annual maintenance costs and 1997
insurance  proceeds  which were only  partially  offset by increased  volume and
improved sales of higher margin products.

Aerospace  Components'  sales  increased  33% compared with the same period last
year,  as shipments  on key  commercial  and military  programs and blade repair
activity  were  higher.  Earnings for the 1998 period  increased  26% due to the
increased  volume and third quarter  improvements in  manufacturing  performance
which were partially offset by higher administrative costs related to the volume
increase and litigation expense.



                                                         12





Handling

Sales in the Handling  segment in the first nine months of 1998  declined 56% to
$143.7 million, compared with $327.3 million in the 1997 period, due to the sale
of the foreign Handling  businesses.  North American Handling sales increased 9%
in the 1998 period over 1997 due to  increased  shipments  which were  partially
offset by lower selling prices.

Operating profit decreased 42% to $4.7 million reflecting the disposition of the
foreign  units.  Handling  North  America's  earnings  increased 70% in the 1998
period over 1997 as the effect of the increased  volume, a favorable  settlement
with a supplier and lower  material  costs were only  partially  offset by sales
pricing  weakness  on 1997  bookings  shipped  in  1998  and  favorable  accrual
adjustments recorded in the first quarter of 1997.

Non-operating 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.  Based on the Company's  recommended  remedy for certain
underwater  sediments at the Duluth Site, 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.

As  discussed  in Note 9 of  Notes  to  Consolidated  Financial  Statements,  on
September 28, 1998, Acme Steel Company and its affiliates filed for relief under
Chapter 11 of the United States  Bankruptcy  Code. Prior to 1986, Acme was known
as  Interlake,  Inc.  In  connection  with the  reorganization  of Acme (the old
Interlake) in 1986, the Company,  then  newly-formed,  indemnified  Acme against
certain  environmental,  tax and other liabilities.  In addition, at the time of
the reorganization  Acme became obligated to the Company with respect to certain
pollution  control bonds  assumed at that time by the Company but  pertaining to
facilities of Acme.  As of September  27,1998,  the  principal  amount of Acme's
obligation to the Company  related to such bonds was $5.5 million.  In the third
quarter,  the  Company  recorded a  non-operating  charge of $4.4  million for a
valuation  allowance  against this  receivable  to a level  consistent  with the
post-filing trading range of Acme's parent corporation's  unsecured public debt.
The Company has retained  legal  counsel to advise it as to the other effects of
the filing on the Company,  including among others any effect upon the Company's
obligation to indemnify Acme with respect to certain liabilities.

Discontinued Operations

Certain  adjustments  to the gain recorded in  connection  with the October 1996
sale of the packaging  businesses  resulted in additional income of $.3 million,
net of income taxes, in the third quarter of 1997. In the first quarter of 1997,
the  Company  received  additional  proceeds  from  the  sale  of its  packaging
businesses resulting in income from discontinued operations of $1.5 million, net
of income taxes.

Extraordinary Loss

During the third quarter of 1998, the Company recorded an extraordinary  loss of
$.2 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
$6.8 million of the Company's Senior Notes.

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.

                                                         13





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 $285.6  million at the end of the third quarter of
1998, down $38.0 million from the 1997 year-end.  Cash and  equivalents  totaled
$5.0 million at the end of the quarter,  compared  with $84.5 million at the end
of 1997,  reflecting  the  repurchase  of $6.8 million of Senior Notes and $24.0
million of Senior Subordinated  Debentures,  the $4.0 million payoff of the ESOP
note, the increase in working  capital  requirements  and capital  expenditures.
Capital  expenditures of $43.4 million in the first nine months of 1998 compared
with  $18.1  million  in 1997,  reflecting  increased  spending  for  expansion,
particularly in the Engineered  Materials segment.  The Company anticipates that
1998 capital spending will be approximately $59.0 million.

The Company  entered  into an  agreement  for a two-year  $75 million  revolving
credit  facility  on July  31,  1998.  If  current  levels  of  performance  are
maintained,  the Company anticipates it will be in compliance with the covenants
under its bank credit agreement and it will have adequate  liquidity to meet its
debt service and operating requirements,  based on expected operating cash flow,
cash on hand, and the availability of borrowings under the Company's bank credit
agreement.

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

Year 2000 Issues and Status

The Company  recognizes the importance of the Year 2000 issues and has initiated
a program of  evaluating,  remediating  and testing  the  systems and  equipment
serving its  businesses for Year 2000  readiness.  The Company is also assessing
the readiness of external parties,  including its suppliers,  vendors,  bankers,
insurers and other service  providers as well as its  customers.  The evaluation
phase is intended to determine the  readiness of internal  systems and equipment
as well as third  parties.  The  remediation  phase  includes  reprogramming  of
software  with  testing  of  specific  modifications,  replacement  of  computer
software and hardware and operating  equipment as well as identifying  solutions
to possible third party  noncompliance.  The testing phase  includes  integrated
testing of all systems which are modified.

The current status of the Company's  state of readiness and expected  completion
dates for  evaluation,  remediation  and testing related to Year 2000 issues are
summarized below:

Expenditures  for Year  2000  readiness  are  principally  the  costs to  modify
existing information system software or microprocessors embedded in equipment in
the Company's  manufacturing  systems. These costs are expected to be minor, and
$.3 million has been  incurred to date  through the end of the third  quarter in
addressing  Year 2000  readiness.  Total costs are expected to approximate  $1.0
million,  including  $.2 million to replace  existing  hardware  and  equipment.
Funding for the  Company's  Year 2000  program  will be  generated  from current
operating  activities,  and IT  department  costs to  address  Year 2000  issues
represent 30% of the Company's  total IT budget.  No other IT projects have been
deferred which would have a material  effect on future  financial  condition and
results of operations.

The Company also plans to replace  certain  non-IT systems at one of its Special
Materials  facilities.  While the replacement of these systems does address some
Year 2000 issues, the Company does not consider the investment in new systems to
be related to the Year 2000 issue as such costs are a necessary  expenditure  to
enhance  future  operations  which  will be  incurred  regardless  of Year  2000
considerations. Total costs to replace these systems will be $1.7 million.

The Company  believes  that in the most likely,  worst case  scenario,  internal
remediation and testing of information  technology  systems and  non-information
technology  systems will be  completed as indicated  above and will have minimal
unfavorable impact on the results of operations and financial condition.  If any
or all of these efforts are delayed,  there could be disruption of the financial
and operating systems at one or more of the business units. Critical third party
vendors,  suppliers and service  providers have been contacted to evaluate their
Year 2000 readiness.  However, external parties providing materials and services
to the Company have been  reluctant to fully  disclose  information  about their
readiness.  Accordingly,  the  Company  cannot  be  assured  there  will  be  no
disruption  of operations  because of vendors and service  providers who are not
fully Year 2000 compliant. Contingency plans will be developed, where necessary,
as part of the remediation phases indicated above, to provide a continued supply
of goods and various services. The Company has also begun contacting significant
customers to determine their compliance.  However, the Company has not completed
these evaluations and cannot determine whether there are vendors,  suppliers and
customers  who will not be compliant on a timely basis or whether the failure of
any of these entities to become compliant could have a material,  adverse effect
on its consolidated results of operations and consolidated financial position.

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  requires  that all  derivative
instruments be recorded on the balance sheet at their fair value. Changes in the
fair value of derivatives are to be recorded each period in current  earnings or
other comprehensive  income,  depending on whether a derivative is designated as
part of a hedge transaction and, if it is, the type of hedge transaction.
Management of the Company has not yet

                                                         15





determined the impact that the adoption of SFAS 133 will have on its earnings or
statement of financial position.  However,  management  anticipates that, due to
its limited use of  derivative  instruments,  the  adoption of SFAS 133 will not
have a  significant  effect  on  the  Company's  results  of  operations  or its
financial position.
