(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 nine-month periods
ended June 30, 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.

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

(3) Earnings per share (EPS) and 10 percent stock dividend -
    ------------------------------------------------------

     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  30,006,000
and 29,977,000  for the three months ended June 30, 2001 and 2000,  respectively
and  29,989,000 and 30,151,000 for the nine months ended June 30, 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
30,459,000  and  30,173,000  for the three  months ended June 30, 2001 and 2000,
respectively  and  30,251,000  and 30,330,000 for the nine months ended June 30,
2001 and 2000,  respectively,  and reflects additional shares in connection with
stock option and other stock-based compensation plans.

                                       6


     Options to purchase approximately  2,996,000 and 5,597,000 shares of common
stock were not included in the  computations  of diluted  earnings per share for
the three  months  ended June 30,  2001 and 2000,  respectively,  and options to
purchase  approximately  3,460,000 and 4,180,000 shares of common stock were not
included in the  computation  of diluted  earnings per share for the nine months
ended June 30, 2001 and 2000, respectively,  because the effects would have been
antidilutive.

     On August 6, 2001 the company's Board of Directors  authorized a 10 percent
common  stock  dividend  payable  on  September  4, 2001 to holders of record on
August 20, 2001. After giving retroactive effect to the stock dividend, proforma
basic and diluted earnings per share would be as follows:

(4) Start-up costs -
    --------------

     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 nine months ended June 30, 2000.

(5) 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 nine months ended June 30, 2001.

(7) Recently issued accounting standards -
    ------------------------------------

     In June 2001 the Financial  Accounting  Standards Board issued Statement of
Financial  Accounting  Standards  Nos.  141 and 142  (SFAS  141 and  SFAS  142),
"Business   Combinations"   and   "Goodwill   and  Other   Intangible   Assets",
respectively. SFAS 141 addresses financial accounting and reporting for business
combinations,  requiring the use of the purchase method of accounting.  SFAS 142
addresses  accounting and reporting for acquired  goodwill and other  intangible
assets.  It eliminates the previous  requirement to amortize  goodwill and other
intangible  assets with indefinite lives and establishes new  requirements  with
respect to the  recognition  and  valuation  of  goodwill  and other  intangible
assets.  The company  anticipates  adopting these  standards for the fiscal year
beginning October 1, 2001.  Amortization of goodwill approximates $2 million per
year. The company is presently  determining  what impact,  if any, that adoption
will have on the carrying value of existing goodwill.

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

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

RESULTS OF OPERATIONS

Three months ended June 30, 2001
- --------------------------------

     Net sales were $289.4  million for the  three-month  period  ended June 30,
2001, an increase of $10.7 million or 3.8%.

     Net sales of the garage doors segment were $109.2  million,  an increase of
$2.4 million or 2.3% compared to last year due primarily to higher unit sales of
residential  garage doors. The increase in sales was principally due to stronger
demand in the retail distribution channel.

     Net sales of the  installation  services  segment  were $68.3  million,  an
increase  of $1.2  million or 1.8%  compared  to last  year.  The  increase  was
primarily a result of sales growth due to expanded product offerings.

     Net sales of the specialty  plastic films  segment were $75.7  million,  an
increase of $11.8 million or 18.5%  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  and by the effect of selling
price adjustments to pass through raw material cost decreases to customers, were
the principal reasons for the increase.

     Net sales of the electronic  information and communication  systems segment
were $42.7  million,  a decrease of $5.1 million or 10.6% compared to last year.
The 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 June
30, 2001 was $19.8  million,  an increase of $2.9  million or 17.4%  compared to
last year.

     Operating income of the garage doors segment was $5.8 million,  an increase
of $.8 million or 17.1% compared to last year. The effect of increased sales and
cost reduction programs were the principal reasons for the increase. The company
anticipates  that garage  doors'  near-term  operating  results will continue to
improve.

     Operating  income for the  installation  services segment was $2.0 million,
approximately the same as last year.

     Operating  income of the specialty  plastic films segment was $9.1 million,
an increase of $4.7 million or 106.5%  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 $2.9 million,  a decrease of $2.6 million or 47.1%  compared to last
year.  The  effect  of  lower  sales  and  increased  research  and  development
expenditures,   including  costs   associated  with  its  previously   announced
technology  initiatives which are expected to total approximately $5 million for
the year, were the principal  reasons for the decrease.  Although it is expected
that this segment  will  continue to be impacted by the  increased  research and
development activities and by reduced orders in its integrated circuit business,
the company anticipates near-term improvement in the segment's core operations.

     Net  interest  expense  decreased  by $.9  million  compared  to last  year
principally due to the effect of debt repayments and lower interest rates.

                                       10

Nine months ended June 30, 2001
- -------------------------------

     Net sales were $841.8  million  for the  nine-month  period  ended June 30,
2001, an increase of $23.4 million or 2.9%.

     Net sales of the garage doors  segment were $306.5  million,  a decrease of
$12.0  million  or 3.8%  compared  to last  year.  Lower  unit  sales due to the
continued effects of a slowing economy,  competitive  markets and winter weather
conditions  in the first half of the year,  partly  offset by higher  unit sales
from improved  operations in the third quarter,  were the principal  reasons for
the decrease.

     Net sales of the  installation  services  segment  were $198.6  million,  a
decrease of $2.5 million or 1.3%  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 $225.5  million,  an
increase  of $35.4  million or 18.6%  compared  to last year.  Higher unit sales
volume both domestically and at Finotech,  the segment's European joint venture,
partly offset by the effect of a stronger U.S. dollar on foreign  operations and
selling  price  adjustments  to pass  through raw  material  cost  decreases  to
customers, were the principal reasons for the increase.

     Net sales of the electronic  information and communication  systems segment
were $130.2  million,  a decrease of $1.2  million or .9% compared to last year.
Higher funding  levels on existing  programs and a full nine months of operating
results  from the search and  weather  radar  business  acquired  last year were
offset by the effect of delays in anticipated  orders in connection with certain
on-going programs.

     Operating  income for all business  segments for the nine months ended June
30, 2001 was $53.0  million,  an increase of $8.9  million or 20.2%  compared to
last year.  Operating results for the nine months ended June 30, 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 $9.3 million,  a decrease
of $3.6 million or 27.8%  compared to last year.  Garage  doors' lower sales and
lower  margins  through  the first  half of the year were  partly  offset by the
effect of cost  reduction  programs  and by higher  sales in the third  quarter.
Unprofitable  operations  in a  commercial  door  product  line and  competitive
pricing also contributed to the segment's reduced operating results for the nine
months.

     Operating income of the installation  services segment was $3.9 million,  a
decrease of $1.4  million or 26.0%  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 $30.7 million,
an increase of $18.0 million or 142.3%  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 $9.1 million,  a decrease of $4.2 million or 31.5%  compared to last
year, primarily due to costs associated with its previously announced technology
initiatives and lower sales.

                                       11

LIQUIDITY AND CAPITAL RESOURCES

     Cash flow  provided by  operations  for the nine months ended June 30, 2001
was  $72.5  million  compared  to $12.2  million  last year  principally  due to
increased earnings and improved working capital management.  Working capital was
$191.5 million at June 30, 2001.

     Net cash used in  investing  activities  during the nine months  aggregated
$19.3  million,  and  principally  consisted  of  capital  expenditures  made in
connection with increasing production capacity.

     Net  cash  used  in  financing   activities  during  the  nine  months  was
approximately  $36.3  million.  Substantially  all of these  cash  flows were in
connection with the repayment of bank borrowings.  During the quarter ended June
30,  2001  the  company's  European   operations  entered  into  new  bank  loan
agreements,  replacing then existing financing arrangements. The new agreements,
which bear interest at variable rates based upon Euribor, include a term loan of
approximately $13 million with maturities through 2004 and revolving credits for
up to  approximately  $20  million.  Subsequent  to June 30,  2001,  outstanding
borrowings under the revolving credits were reduced by approximately $9 million.

     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.
