              ----------------------------------------------------
                                  (Unaudited)

(1)  Basis of Presentation -
     ---------------------

     The accompanying unaudited condensed consolidated financial statements have
been prepared in accordance with generally  accepted  accounting  principles for
interim financial information and with the instructions to Form 10-Q and Article
10 of Regulation  S-X.  Accordingly,  they do not include all of the information
and footnotes required by generally accepted accounting  principles for complete
financial statements. In the opinion of management,  all adjustments (consisting
of normal recurring  adjustments)  considered  necessary for a fair presentation
have been included.  Operating results for the three-month and six-month periods
ended March 31, 2001 are not  necessarily  indicative of the results that may be
expected for the year ending  September 30, 2001. The balance sheet at September
30, 2000 has been derived from the audited  financial  statements  at that date.
For further  information,  refer to the  consolidated  financial  statements and
footnotes  thereto  included in the company's  annual report to shareholders for
the year ended September 30, 2000.

(2)  Inventories -
     -----------

     Inventories,  stated at the lower of cost (first-in,  first-out or average)
or market, are comprised of the following:



                                                 March 31,      September 30,

(3)  Earnings per share (EPS) -
     ------------------------

     Basic EPS is calculated by dividing  income by the weighted  average number
of shares of common stock  outstanding  during the period.  The weighted average
number of shares of common stock used in  determining  basic EPS was  29,990,000
and 30,010,000 for the three months ended March 31, 2001 and 2000,  respectively
and  29,980,000 and 30,238,000 for the six months ended March 31, 2001 and 2000,
respectively.

     Diluted EPS is calculated by dividing income by the weighted average number
of shares of common stock  outstanding plus additional  common shares that could
be issued in  connection  with  potentially  dilutive  securities.  The weighted
average  number of shares of common  stock used in  determining  diluted EPS was
30,155,000  and  30,190,000  for the three months ended March 31, 2001 and 2000,
respectively  and  30,147,000  and 30,409,000 for the six months ended March 31,
2001 and 2000,  respectively,  and reflects additional shares in connection with
stock option and other stock-based compensation plans.

                                       6

     Options to purchase approximately  4,733,000 and 4,195,000 shares of common
stock were not included in the  computations  of diluted  earnings per share for
the three and six-month  periods  ended March 31,  2001 and 2000,  respectively,
because the effects would have been antidilutive.

     Effective  October  1,  1999 the  company  adopted  the  provisions  of the
American  Institute of Certified Public  Accountants'  Statement of Position No.
98-5 (SOP  98-5),  "Reporting  on the Costs of  Start-Up  Activities".  SOP 98-5
requires that, at the date of adoption,  costs of start-up activities previously
capitalized  be  written-off  as a cumulative  effect of a change in  accounting
principle, and that after adoption, such costs are to be expensed as incurred.

     Consequently,  in the first quarter of fiscal 2000, the company's 60%-owned
joint venture  wrote-off  costs that were  previously  capitalized in connection
with the start-up of the venture and the implementation of additional production
capacity.  The  cumulative  effect of this  change in  accounting  principle  is
$5,290,000 (net of $3,784,000 income tax effect).  The minority interest's share
of the net charge is  $2,116,000  and is  included  as an  offsetting  credit in
"Minority  interest" in the  accompanying  Condensed  Consolidated  Statement of
Income for the six months ended March 31, 2000.

(6)  Pension curtailment gain -
     -------------------------

     Pursuant to the provisions of Statement of Financial  Accounting  Standards
No. 88,  "Accounting for Settlements and Curtailments of Defined Benefit Pension
Plans and for Termination Benefits,"  modifications to certain employee benefits
and related benefit freezes resulted in the recognition of a pretax  curtailment
gain of approximately $3.1 million in the quarter ended March 31, 2001.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
          -----------------------------------------------------------

                           AND RESULTS OF OPERATIONS
                           -------------------------

RESULTS OF OPERATIONS

Three months ended March 31, 2001
- ---------------------------------

     Net sales were $264.2  million for the  three-month  period ended March 31,
2001, an increase of $5.3 million or 2%.

     Net sales of the garage  doors  segment were $87.9  million,  a decrease of
$4.0 million or 4.3%  compared to last year due primarily to lower unit sales of
residential  garage  doors.  The  decrease in sales was  principally  due to the
continued effects of a slowing economy,  competitive  markets and winter weather
conditions.

     Net sales of the  installation  services  segment  were  $62.5  million,  a
decrease  of $2.7  million  or 4.2%  compared  to last  year.  The  decline  was
primarily a result of  decreased  demand due to softer  housing  markets,  which
offset sales growth due to expanded product offerings.

     Net sales of the specialty  plastic films  segment were $77.0  million,  an
increase of $11.7 million or 17.9%  compared to last year.  Higher unit sales in
both the segment's domestic and foreign operations,  partly offset by the effect
of a stronger U.S. dollar on foreign  operations,  was the principal  reason for
the increase.

     Net sales of the electronic  information and communication  systems segment
were $42.7 million  compared to $43.5 million last year. The slight  decrease in
sales was  principally  due to delays in anticipated  orders in connection  with
certain on-going programs.

     Operating income for all business segments for the three months ended March
31, 2001 was $13.1  million,  an increase of $4.6  million or 55.2%  compared to
last year.  Operating  results for the quarter  ended March 31, 2001  included a
pretax pension curtailment gain of approximately $3.1 million,  which was evenly
divided between the specialty plastic films and garage doors segments.

     Operating loss of the garage doors segment was $1.4 million, compared to an
essentially  break-even quarter last year.  Profitability was adversely impacted
by the decreased  sales and lower  margins,  partly offset by the effect of cost
reduction  programs.  The segment also experienced a loss from a commercial door
product  line for which  strategic  alternatives  are being  explored.  Although
impacted by a slowing economy and competitive markets, the company is cautiously
optimistic that garage doors'  profitability  will improve in the latter part of
the year.

     Operating  income for the  installation  services  segment  was $.7 million
compared to $.9 million last year. The decrease was principally due to the sales
decline and higher distribution and selling costs.

     Operating income of the specialty  plastic films segment was $11.9 million,
an increase of $8.3 million or 229.4%  compared to last year.  Increased  volume
and  manufacturing  efficiencies,  both  domestically  and in  Europe,  were the
primary  reasons for the  improvement in the segment's  operating  results,  and
further strong performance is anticipated.

     Operating income of the electronic  information and  communication  systems
segment was $1.8 million,  a decrease of $2.1 million or 53.1%  compared to last
year, primarily due to costs associated with its previously announced technology

                                       9


initiatives,  which are expected to total approximately $5 million for the year,
and the effect of slightly  lower  sales.  The company is  optimistic  that this
segment's core  operations  will improve  towards the end of the year,  although
near-term  earnings  will continue to be impacted by the increased  research and
development activities.

Six months ended March 31, 2001
- -------------------------------

     Net sales were $552.4  million  for the  six-month  period  ended March 31,
2001, an increase of $12.7 million or 2.4%.

     Net sales of the garage doors  segment were $197.2  million,  a decrease of
$14.5  million  or 6.8%  compared  to last  year.  Lower  unit  sales due to the
continued effects of a slowing economy,  competitive  markets and winter weather
conditions were the principal reasons for the decrease.

     Net sales of the  installation  services  segment  were $130.3  million,  a
decrease of $3.7 million or 2.8%  compared to last year.  The adverse  impact of
softer housing  markets was mitigated  somewhat by growth from expanded  product
offerings.

     Net sales of the specialty  plastic films segment were $149.8  million,  an
increase  of $23.5  million or 18.7%  compared  to last year.  Higher unit sales
volume at Finotech,  the  segment's  European  joint  venture and  domestically,
partly offset by the effect of a stronger U.S. dollar on foreign operations, was
the principal reason for the increase.

     Net sales of the electronic  information and communication  systems segment
were $87.4  million,  an increase of $3.8 million or 4.6%  compared to last year
due to higher  funding  levels on  existing  programs  and a full six  months of
operating results from the search and weather radar business acquired last year.

     Operating  income for all business  segments for the six months ended March
31, 2001 was $33.2  million,  an increase of $6.0  million or 22.0%  compared to
last year.  Operating results for the six months ended March 31, 2001 included a
pretax pension curtailment gain of approximately $3.1 million,  which was evenly
divided between the specialty plastic films and garage doors segments.

     Operating  income of the garage doors segment was $3.5 million,  a decrease
of $4.4 million or 55.7%  compared to last year.  Garage  doors' lower sales and
lower margins, partly offset by the effect of cost reduction programs, adversely
impacted  profitability  in the first six months.  Unprofitable  operations in a
commercial  door product line and  competitive  pricing also  contributed to the
segment's reduced operating results for the six months.

     Operating income of the installation  services segment was $1.9 million,  a
decrease of $1.4  million or 42.3%  compared to last year.  Higher  margins from
improved  product  mix and  expanded  product  offerings  were  offset by higher
distribution and selling costs.

     Operating income of the specialty  plastic films segment was $21.6 million,
an increase of $13.4 million or 161.3%  compared to last year.  The increase was
primarily due to higher unit sales in both the  segment's  domestic and European
operations and related manufacturing efficiencies.

     Operating income of the electronic  information and  communication  systems
segment was $6.1 million,  a decrease of $1.6 million or 20.3%  compared to last
year, primarily due to costs associated with its previously announced technology
initiatives.

     Net interest  expense  increased by $1.0 million  principally due to higher
levels of outstanding debt from acquisitions in 1999 and 2000.

                                       10

LIQUIDITY AND CAPITAL RESOURCES

     Cash flow  provided by  operations  for the six months ended March 31, 2001
improved to $41.1 million compared to $2.0 million last year, principally due to
increased earnings and improved working capital management.  Working capital was
$185.8 million at March 31, 2001.

     Net cash used in investing activities during the six months aggregated $6.2
million,   including   capital   expenditures  of  approximately   $8.7  million
principally made in connection with increasing production capacity.

     Net  cash  used  in  financing   activities   during  the  six  months  was
approximately  $20.9  million.  Substantially  all of these  cash  flows were in
connection with the repayment of bank borrowings.

     Anticipated cash flows from  operations,  together with existing cash, bank
lines of credit  and lease  line  availability,  should be  adequate  to finance
presently  anticipated working capital and capital expenditure  requirements and
to repay long-term debt as it matures.
