(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 and six-month periods ended
March  31,  2000  are not  necessarily  indicative  of the  results  that may be
expected for the year ending  September 30, 2000. The balance sheet at September
30, 1999 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, 1999.

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

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

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

     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  30,010,000
and 30,395,000 for the three months ended March 31, 2000 and 1999,  respectively
and  30,238,000 and 30,386,000 for the six months ended March 31, 2000 and 1999,
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
30,190,000  and  30,395,000  for the three months ended March 31, 2000 and 1999,
respectively  and  30,409,000  and 30,631,000 for the six months ended March 31,
2000 and 1999,  respectively,  and reflects additional shares in connection with
stock option and other  stock-based  compensation  plans (180,000 shares for the
three months ended March 31, 2000, 171,000 shares for the six months ended March
31, 2000 and 245,000 shares for the six months ended March 31, 1999).

     Options to purchase approximately  4,195,000 and 5,297,000 shares of common
stock were not included in the computation of diluted earnings per share for the
three  months  ended  March 31,  2000 and 1999,  respectively,  and  options  to
purchase  approximately  4,195,000 and 3,018,000 shares of common stock were not
included in the  computation  of diluted  earnings  per share for the six months
ended March 31, 2000 and 1999, respectively, because the effects would have been
antidilutive.

    -----------------

     The company's  reportable  business  segments are as follows - Garage Doors

     As a result of an  acquisition  during the six months ended March 31, 2000,
the electronic  information and communication systems segment's assets increased
by approximately $16,000,000, and the garage doors segment's assets increased by
approximately  $4.5  million in  connection  with the  purchase of a  previously
leased facility.

(5) 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  Statements of
Income.

(6) Restructuring charge -
    --------------------

     In March 1999 the company  recorded a  restructuring  charge in  connection
with the closing of a garage door manufacturing  facility in order to streamline
operations and improve  efficiency.  Approximately  $1,350,000 of  restructuring
costs were accrued;  through March 31, 2000 approximately $777,000 has been paid
for employee severance and related benefits and $328,000 has been paid for lease
and related costs.  The remaining accrual will be paid by September 30, 2000.

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

GENERAL

     The following  information is presented in accordance  with related segment
results  presented  in Note 4 of  "Notes  to  Condensed  Consolidated  Financial
Statements."

RESULTS OF OPERATIONS

Three months ended March 31, 2000
- ---------------------------------

     Net sales were $258.9  million for the  three-month  period ended March 31,
2000, an increase of $22.5 million or 9.5%.

     Net sales for the garage doors  segment were $91.8  million,  a decrease of
$1.3 million or 1.4% compared to last year.  Unit volume of  residential  garage
doors increased  compared to last year's quarter,  offset by the effect of price
competition, lower unit sales of commercial doors and by the sale in fiscal 1999
of a commercial  product line that had net sales of  approximately $3 million in
the second quarter of fiscal 1999.

     Net sales for the specialty  plastic films segment were $65.4  million,  an
increase of $20.4 million or 45.2% compared to last year.  Substantially  higher
unit sales volume at Finotech,  the  segment's  European  joint  venture was the
principal reason for the increase.

     Net sales for the electronic  information and communication systems segment
were $43.5  million,  a decrease of $6.6 million or 13.2% compared to last year.
The decrease in sales was  principally  due to delays in  anticipated  orders on
international  radar programs and lower revenues in the second quarter of fiscal
2000 on  programs  that  were in  development  in 1999 but  have  not yet  fully
transitioned  to  production,  partly offset by sales of an acquired  search and
weather radar business.

     Net sales for the  installation  services  segment were $65.2  million,  an
increase  of $9.9  million or 17.9%  compared  to last year.  The  increase  was
primarily due to the inclusion for the entire second quarter of fiscal 2000 of a
company which was acquired during the second quarter of fiscal 1999.

     Operating income for all business segments for the three months ended March
31, 2000 was $8.4  million,  an increase of $5.2  million or 162.8%  compared to
last  year.  The  increase  was  principally  due to  substantial  volume-driven
improvement  in specialty  plastic  films'  European  joint  venture and related
manufacturing efficiencies.

     Operating  results for the garage doors segment was  approximately the same
as  last  year.  Increased   profitability  due  to  favorable  product  mix  in
residential doors,  lower raw material costs and manufacturing  efficiencies was
offset by higher  operating  costs to  support  the  segment's  standing  as the
exclusive  supplier of residential  garage doors to The Home Depot in the United
States and Canada.  The segment also  experienced  unprofitable  operations in a
commercial door product line and competitive pricing.

     Operating income for specialty plastic films was $3.6 million compared to a
loss of $.9  million  last year.  The  substantial  increase in net sales of the
segment's European joint venture and resultant manufacturing efficiencies due to
higher unit volume was the  principal  reason for the  improvement  in operating
income.

     Operating income for the electronic  information and communication  systems
segment was $3.9 million,  an increase of $.6 million or 16.8%  compared to last
year.  Profitability  improved due primarily  from higher  aggregate  margins on
certain programs which have transitioned from development to production and from
earnings of the acquired  search and weather  radar  business,  partly offset by
increased bid and proposal expenditures.

     Operating income of the installation  services segment was $.9 million,  an
increase of $.2 million  compared to last year. The increase was principally due
to the  inclusion  of  earnings of an  acquired  company  for the entire  second
quarter of fiscal 2000,  partly  offset by higher  distribution  and labor costs
from expanded product offerings.

     Net interest  expense  increased by $.8 million  principally  due to higher
levels of outstanding debt from acquisitions in 1999 and 2000.

Six months ended March 31, 2000
- -------------------------------

     Net sales were $539.7  million  for the  six-month  period  ended March 31,
2000, an increase of $44.7 million or 9.0%.

     Net sales for the garage doors segment were $211.7  million,  a decrease of
$5.4 million or 2.5% compared to last year.  Unit volume of  residential  garage
doors  increased  compared  to last year's  first half,  offset by the effect of
price  competition,  lower unit sales of  commercial  doors and by the sale last
year of a commercial product line that had net sales of approximately $7 million
in the first half of fiscal 1999.

     Net sales for the specialty  plastic films segment were $126.2 million,  an
increase of $30.9 million or 32.4% compared to last year.  Substantially  higher
unit sales volume at Finotech,  the  segment's  European  joint  venture was the
principal reason for the increase.

     Net sales for the electronic  information and communication systems segment
were $83.6  million,  a decrease of $8.5 million or 9.2%  compared to last year.
The decrease in sales was  principally  due to delays in  anticipated  orders on
international radar programs and lower revenues in the first half of fiscal 2000
on programs that were in development in 1999 but have not yet fully transitioned
to  production,  partly offset by sales of an acquired  search and weather radar
business.

     Net sales for the  installation  services  segment were $134.0 million,  an
increase of $27.9 million or 26.3%  compared to last year.  The increase was due
to the  inclusion in the first six months of fiscal 2000 of a company  which was
acquired  during the second  quarter of fiscal 1999,  and  internal  growth from
expanded product offerings.

     Operating  income for all business  segments for the six months ended March
31, 2000 was $27.2  million,  an increase of $9.0  million or 49.4%  compared to
last  year.  The  increase  was  principally  due to  increased  unit  volume in
specialty  plastic  films'  European  joint  venture and  related  manufacturing
efficiencies and increased  margins in electronic  information and communication
systems.

     Operating income for the garage doors segment was $7.9 million,  a decrease
of $.7 million or 8.0%  compared to last year.  Increased  profitability  due to
favorable  product  mix in  residential  doors,  lower  raw  material  costs and
manufacturing  efficiencies  was offset by higher operating costs to support the
segment's  expansion of sales to retail channels.  Unprofitable  operations in a
commercial  door product line and  competitive  pricing also  contributed to the
segment's reduced operating results for the first half of fiscal 2000.

     Operating income for specialty plastic films was $8.3 million,  an increase
of $7.5  million  compared  to last  year.  The  increase  in net  sales  of the
segment's European joint venture and resultant manufacturing efficiencies due to
higher unit volume was the  principal  reason for the  improvement  in operating
income.

     Operating income for the electronic  information and communication  systems
segment was $7.7 million,  an increase of $1.4 million or 21.7% compared to last
year.  The increase in  operating  income  reflects  improved  profitability  on
certain  programs that have  transitioned  from  development  to production  and
earnings of the acquired  search and weather  radar  business,  partly offset by
increased bid and proposal expenditures.

     Operating income of the installation  services segment was $3.3 million, an
increase of $.8 million  compared to last year. The increase was principally due
to the  inclusion of earnings of an acquired  company,  partly  offset by higher
distribution and labor costs from expanded product offerings.

     Net interest  expense  increased by $1.4 million  principally due to higher
levels of outstanding debt from acquisitions in 1999 and 2000.

LIQUIDITY AND CAPITAL RESOURCES

     Cash flow  provided by  operations  for the six months ended March 31, 2000
improved to $2.0  million  compared to cash used by  operations  of $4.7 million
last year,  principally due to increased earnings.  Working capital increased to
$214.8  million at March 31, 2000.  The increase was  principally  due to higher
inventory requirements in connection with expansion of the garage door segment's
retail business and with expanded product offerings in the installation services
segment.

     During  the six  months  ended  March 31,  2000 net cash used in  investing
activities was approximately $30.2 million. The company had capital expenditures
of approximately  $22.7 million,  principally made in connection with increasing
production  capacity and with the purchase of a  previously  leased  garage door
manufacturing  facility for  approximately  $4.5 million.  Also,  the electronic
information  and  communication  systems  segment  acquired a search and weather
radar business for approximately $16 million,  of which $12 million was financed
under bank credit  lines with the  balance  expected to be paid during the third
quarter of fiscal 2000.

     Net cash provided by financing activities during the six months ended March
31, 2000 was  approximately  $24.8 million.  Borrowings  under bank credit lines
were used to finance an acquisition,  capital  expenditures  and working capital
requirements.   Also,  since  September  30,  1999  the  company  has  purchased
approximately 512,000 shares of its Common Stock for approximately $3.6 million,
and  increased  its stock  buyback  program from  1,500,000  shares to 3,000,000
shares.  Additional  purchases  will be made from  time-to-time,  depending upon
market conditions, at prices deemed appropriate by management.

     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.
