ITEM 1. BUSINESS.
 
  PLY GEM Industries, Inc., a Delaware corporation ("Ply Gem", hereinafter
with its subsidiaries referred to collectively as the "Company"), was
originally incorporated in 1946 in New York and reincorporated in Delaware in
1987. The Company is a leading manufacturer and distributor of a wide range of
specialty products for the home improvement industry. The Company believes
that it is among the nation's largest manufacturers of wood windows, vinyl
siding and accessories, and vinyl windows, and one of the major suppliers of
specialty wood and other related products. Each of the Company's ten wholly-
owned subsidiaries and its one division have achieved a leading market
position within their respective niches of the home improvement industry.
 
  The home improvement industry includes products designed for all remodeling,
repair and alteration of residential structures, whether the work is performed
by the homeowner (the "do-it-yourselfer" or "D-I-Y"), or by a professional
contractor. Home improvement products, which in some cases are also used in
new construction applications, are sold either through retailers or specialty
wholesale distributors that in turn sell to retailers, contractors and
builders. The success of the recently introduced warehouse home center format,
such as that utilized by Home Depot, continues to change the traditional way
in which home improvement products are sold.
 
  The Company's primary objective is to become the supplier of choice to the
home improvement industry for high margin specialty products. The Company
believes that it is uniquely positioned to provide products and services to
the major home center retailers, which the Company believes is the fastest
growing segment of the home improvement industry.
 
  The Company's products are distributed through an extensive network which
includes major retail home center chains, specialty home remodeling
distributors, lumber and building products wholesalers, professional
contractors and Company operated distribution centers. The products are
marketed throughout the United States, Canada and Puerto Rico through Company
sales personnel and independent representatives.
 
  The Company operates predominantly in one business segment -- Home
Improvement Products. Prior to 1992, the Company reported in two industry
segments, Home Improvement Products and Home Products. The operations of the
latter segment, consisting of manufacturing and distribution of disposable
paper and cloth vacuum cleaner bags, have become less significant over the
past several years and as a result the Home Products operations are not
material to an understanding of the Company's business taken as a whole.
 
                           BUSINESSES OF THE COMPANY
 
  The Company operates in four primary business groups: Windows, Doors and
Siding; Specialty Wood Products; Distribution; and Home Products. Set forth
below are the operating entities within each group and the year in which the
entity was acquired by the Company. Ply*Gem Manufacturing is a division of the
Company and constitutes the Company's original business.

WINDOWS, DOORS AND SIDING
 
  SNE Enterprises, Inc: SNE is a major manufacturer of wood windows, competing
with companies such as Andersen, Marvin and Pella. The Company believes that it
is the second largest supplier of wood windows to the major home center
retailers.
 
  SNE manufactures a full line of wood windows and patio doors, glass and
polycarbonate skylights, and wooden interior bifold doors and shutters. Its
products are sold under the Crestline(R) and Vetter(R) brand names and include
double hung, casement, sliding and awning windows as well as hinged and sliding
patio doors. SNE will shortly introduce a window that offers the maintenance
free and insulating benefits of a solid vinyl window yet has a wood interior
that can be painted or stained. SNE's windows are available primed, or with an
exterior cladding of either aluminum or vinyl. They are available in both
custom and stock sizes, and are sold through an extensive network of home
centers, lumber and building materials retailers, and specialized value added
distributors. SNE's products are primarily for the home improvement market.
 
  The market for wood windows is highly competitive. SNE differentiates itself
from its competition by pursuing a dual brand strategy, having a distribution
base in both the remodeling and new construction markets, extensive custom
design and manufacturing capabilities, and a superior field service and support
network. In addition, SNE's strategy of manufacturing window components at its
main facility in Central Wisconsin for final assembly at one of four
strategically located assembly/distribution centers, allows for the delivery of
product to customers on a just-in-time basis. The Company believes that SNE
will continue to grow as its existing products gain brand recognition from
cooperative and other advertising programs with its retail customers, and as it
introduces new products. Furthermore, SNE is exploring opportunities to expand
its business into new geographic markets.
 
  Variform, Inc.: Variform is a producer of vinyl siding in the United States
and a leading supplier to the major home center retailers. Its vinyl siding,
soffit and accessories are produced in a variety of patterns and colors,
including woodgrains. Vinyl siding is used in both remodeling and new
construction applications and has captured an increasing share of the market
for exterior siding materials (which primarily includes wood, aluminum and
masonry) due to its ease of installation, durability and low maintenance
requirements.
 
  Vinyl siding is sold to either specialized wholesale distributors who in turn
sell directly to remodeling contractors (one-step distribution), or to building
materials distributors who sell to home centers and lumberyards who in turn
sell to remodeling contractors (two-step distribution). While Variform sells
through both channels of distribution, it focuses on the two-step market, where
management believes it is a dominant supplier to the major home center
retailers and retail lumber yards. The Company believes that Variform is able
to compete on favorable terms as a result of its broad distribution coverage,
high quality innovative products, and production efficiency. Additionally,
Variform is strongest in the retail segment of the market,
 
                                       2
<PAGE>
 
which continues to grow at a rate that is faster than the overall market, as
warehouse retailers continue to take business away from the traditional one-
step market by offering remodeling contractors a "one-stop-shop" for all of
their home improvement materials needs.
 
  Great Lakes Window, Inc.: Great Lakes is a manufacturer of high quality,
energy efficient, maintenance free vinyl replacement windows. Its products
include double hung, casement, sliding and awning windows as well as hinged and
sliding patio doors. Great Lakes offers a wide selection of products, including
a variety of exterior colors and interior woodgrains, several different grille
patterns and a wide assortment of glass options. Great Lakes products are
primarily used in replacement applications, where windows and patio doors are
manufactured for a specific order on a custom size basis. Accordingly, Great
Lakes maintains relatively little finished goods inventory. Great Lakes has
recently introduced a vinyl window to penetrate the new construction market
which will be sold primarily through two-step distribution.
 
  Great Lakes sells its products through its highly trained sales force. It
sells its products to specialty window distributors who in turn sell to
remodeling contractors, and direct to large remodeling companies. The Company
believes that Great Lakes is able to compete successfully due to the breadth
and quality of its product offering, and its merchandising support that the
Company believes is one of the best in the industry. In addition, Great Lakes
has been the forerunner in introducing new designs to the industry. Great
Lakes' innovative locking system, interior woodgrains and its use of various
glass treatments, are a few examples of innovations that distinguish Great
Lakes from its competition. Great Lakes expects to continue to develop new
designs and features for its products in the future.
 
  Richwood Building Products, Inc.: Richwood is a manufacturer of siding
accessories to the remodeling and new construction markets. Siding accessories
include blocks, which allow for the flush mounting of items like light fixtures
to the exterior of a home, and gable vents. Their products are sold through a
network of manufacturers representatives and directly to home centers,
lumberyards and wholesale distributors of building materials, electrical and
plumbing products. Richwood is the only manufacturer of siding accessories to
offer a color selection that matches the colors offered by most, if not all,
major manufacturers of vinyl siding in the United States and Canada.
 
SPECIALTY WOOD PRODUCTS
 
  Hoover Treated Wood Products, Inc: Hoover is a producer of pressure treated
wood products, selling to home center chains, lumberyards and building
materials retailers and wholesalers. Its products include lumber and plywood
which have been treated for fire retardancy and for protection against moisture
and insect infestation.
 
  Sagebrush Sales, Inc.: Sagebrush is a manufacturer and distributor of
specialty lumber and building products serving the home improvement and
building materials markets in the Southwest.
 
  Goldenberg Group, Inc.: Goldenberg is a West Coast manufacturer and
distributor of furniture components, laminates and board products to furniture
manufacturers and other original equipment manufacturers, building material
retailers and wholesalers.
 
  Ply*Gem Manufacturing is a manufacturer and distributor of decorative wall
coverings. Its products include decorator paneling, planking and tileboard for
the home improvement market. Ply Gem Manufacturing recently introduced a
complete line of imported ceramic, porcelain and marble floor tile marketed
through home centers and lumber yards.
 
  Continental Wood Preservers, Inc.: Continental is a Midwestern manufacturer
of pressure treated wood products for home improvement retailers and
lumberyards in the Midwest.
 
  While the specialty wood products industry is very competitive, the Company
believes it is able to compete effectively by providing superior customer
service, outstanding quality and, wherever possible,
 
                                       3
<PAGE>
 
proprietary products. The companies within the group focus on high margin,
niche markets within the broader defined wood products industry which tends to
be commodity driven. Its products are sold through home center retailers and
wholesalers of building materials. The Company believes that growth of this
segment of its business will result from continued expansion of its share of
the growing home center market.
 
DISTRIBUTION
 
  Allied Plywood Corporation: Allied is a national distributor of a broad range
of high end specialty wood and wood related products, including hardwood
plywood, melamine and other laminated board products, hardwood lumber, solid
surface materials and cabinet hardware. It is also a major importer of Russian
wood products, through its affiliate, Russian Wood Express Inc. ("Russian
Wood"). Allied's customers are industrial woodworkers, including cabinet
manufacturers, architectural millworkers, and manufacturers of store fixtures,
furniture, signs and exhibits. Allied sells its products through an extensive
network of twelve company operated warehouse facilities and utilizes numerous
public warehouses located in various major port cities. Sales are generated by
a well trained and experienced sales force.
 
  Allied differentiates itself from its competitors, which primarily include
local independent distributors, by its superior customer service, geographic
coverage and breadth of product line. As a result, it has become a preferred
distributor of many products, selling them on an exclusive, or limited
exclusive, basis.
 
  The Company believes that Allied's future growth will be from the
introduction of new products, expansion of its customer base and the
development of further opportunities through Russian Wood. Allied recently
began to penetrate the retail home center market with some of its products and,
the Company believes, will increase its sales to that industry segment.
 
HOME PRODUCTS
 
  Studley Products, Inc.: Studley is a manufacturer of disposable cloth and
paper vacuum cleaner bags. In addition, it sells related floor care products,
grass catcher bags for the lawn care market, and filtration products for use in
pollution control applications. Studley's products are sold to manufacturers of
vacuum cleaners, mass merchandisers and other retailers and recently to the
retail home center market and other retailers.
 
  Even though the market is very competitive, Studley is able to compete on the
basis of its technical expertise in the design and manufacture of its products,
and in its use of high performance materials. Studley recently introduced an
innovative new vacuum cleaner bag that is able to capture pollen and other
allergy causing bacteria through the use of high performance materials. The
continued introduction of new products and the fact that many consumers are now
likely to own more than one vacuum cleaner are expected to provide
opportunities for future growth.
 
PRODUCTION AND FACILITIES
 
  The Windows, Doors and Siding group operates fifteen manufacturing and
warehouse facilities in the United States and one in Canada. Vinyl siding is
produced by an extrusion process which forms siding through various dies from
certain resin compounds, primarily polyvinyl chloride. Siding accessories are
manufactured through an injection molding process using proprietary mold
designs. Insulated vinyl framed replacement windows are manufactured, using a
patented process, from insulated glass and vinyl extrusions. The manufacturing
process of wood windows and patio doors involves cutting and shaping of
components that are assembled with high speed tools. Final assembly of most
wood window and door products takes place in four distribution centers located
in the Eastern and Midwestern United States. The manufacturing plants generally
operate in a "make-to-order" environment. In 1993, Variform completed
construction of a 75,000 square foot vinyl siding manufacturing facility in
Jasper, Tennessee and Great Lakes completed a 90,000 square foot plant
expansion at its vinyl window manufacturing facility in Toledo, Ohio.
 
                                       4
<PAGE>
 
  The Specialty Woods group operates thirteen manufacturing and warehouse
facilities in the United States. The treatment process of wood products
generally involves vacuum pressure impregnation of chemicals into the wood in
an enclosed vessel to ensure thorough penetration to meet industry and
government standards. Some of the wood is kiln dried after treatment to remove
moisture imparted during the pressure impregnation process, providing a clean,
dry and easily handled product. The Company's high-speed laminating production
facilities in Gloucester City, New Jersey afford flexibility in laminating
paper and vinyl to various substrate materials. Furniture components are
manufactured from particle board or fiberboard which is machined to customer
specifications. Several unique proprietary processes are employed to
manufacture these products efficiently. Specialty lumber products, including
siding, decking and paneling are manufactured by the Company in three
facilities with a combined annual production capacity in excess of 100 million
board feet.
 
  Distribution operates twelve distribution centers located primarily in the
East and utilizes numerous public warehouses located in various major port
cities.
 
  Disposable and cloth vacuum cleaner bags are manufactured at two facilities
in the United States and one in Canada. Disposable paper vacuum cleaner bags
are manufactured on highly automated equipment, the major part of which was
designed and built by the Company. Cloth vacuum cleaner bags are manufactured
by cutting fabric to a preformed pattern which is then sewn into the finished
product and packaged. The Company is continuously engaged in designing vacuum
cleaner bags for new vacuum cleaner models.
 
RAW MATERIALS
 
  The principal raw materials used in the manufacture of the Company's products
are polyvinyl chloride, polypropylene, glass, vinyl extrusions, particle board,
fiberboard, plywood, various species of lumber such as pine, spruce, luaun,
hemlock and fir, various chemicals, filter paper, woven and non woven fabric,
and paper.
 
  The Company purchases its raw materials from a large number of domestic and
international sources. The Company believes that there are alternative sources
of supply in the event of its inability to purchase from its present suppliers.
 
SEASONALITY
 
  The Company's home improvement business is seasonal, particularly in the
Northeast and Midwest regions of the United States where inclement weather
during the winter months usually reduces the level of activity in both the home
improvement and new construction markets. The Company's lowest sales levels
usually occur during the first and fourth quarters. Since a high percentage of
the Company's manufacturing overhead and operating expenses are relatively
fixed throughout the year, operating income tends to be lower in quarters with
lower sales. Inventory and borrowings to satisfy working capital requirements
are usually at their highest level during the second and third quarters.
 
BACKLOG
 
  In general, the Company does not produce against a backlog of firm orders;
production is geared primarily to the level of incoming orders and to
projections of future demand. Significant inventories of finished goods, work-
in-process and raw materials are maintained to meet delivery requirements of
customers.
 
  Hoover and Continental maintain a steady backlog of firm orders to be filled
in an amount representing approximately 7% of their annual sales. Distribution
consists of warehouse operations where orders are filled from stock and where
there is no significant backlog.

EMPLOYEES
 
  On January 3, 1994, Monte R. Haymon became President, Chief Operating Officer
and a member of the Board of Directors of Ply Gem. Prior to joining Ply Gem,
Mr. Haymon was President and Chief Executive Officer of a $2 billion
manufacturing company. Mr. Haymon has over 20 years of experience in
successfully managing multiple business units and achieving outstanding
financial performance.
 
  At December 31, 1993 approximately 4,000 persons were employed by the
Company. Approximately 1,300 of such employees are covered by collective
bargaining agreements which expire at various times over the next three years.
The Company has not had any significant work stoppages and considers its
relations with its employees to be good.
 
ITEM 2. PROPERTIES.
 
  The Windows, Doors and Siding group operates fifteen manufacturing and
warehouse facilities in the United States and one in Canada ranging in size
from approximately 20,000 square feet to 660,000 square feet. Of these
facilities, nine are owned, and seven are leased under net leases that expire
at various dates through 2016. The group's manufacturing facilities operated at
ranges of approximately 75% to 95% of capacity during 1993.
 
  The Specialty Woods group has thirteen manufacturing and warehouse facilities
in the United States ranging in size from approximately 35,000 square feet to
215,000 square feet. Of these facilities, seven are owned and six facilities
are leased under net leases that expire at various dates through 2005. The
group's manufacturing facilities operated at ranges of approximately 55% to 90%
of capacity during 1993.
 
  Distribution operates twelve distribution centers located primarily in the
East ranging in size from approximately 16,000 square feet to 70,000 square
feet. Two facilities are owned and ten facilities are leased under leases that
expire at various dates through 1998.
 
  Home Products has two manufacturing facilities in the United States and one
in Canada. These facilities range in size from approximately 39,000 square feet
to 160,000 square feet and are leased by the company under leases that expire
at various dates through 2007. The facilities operated at ranges of
approximately 60% to 65% of capacity during 1993.
 
  The Company's building, machinery and equipment have been generally well
maintained, are in good operating condition and are adequate for current and
future production requirements.
 
  The Company's executive offices are located at 777 Third Avenue, New York,
New York and consist of 9,500 square feet of office space which is leased
through 1999.
 
ITEM 3. LEGAL PROCEEDINGS.
 
  Hoover, a wholly-owned subsidiary of Ply Gem, is a defendant, along with many
other parties, in a number of commercial lawsuits, including a purported class
action on behalf of certain Maryland homeowners, alleging property damage
caused by alleged defects in certain pressure treated interior wood products it
produced and sold through August, 1988. Sales of this product constituted less
than 3% of the total sales of Ply Gem and its subsidiaries on a consolidated
basis during the period January 1, 1984 through December 31, 1990. Ply Gem is
also a defendant in many of these suits. The number of lawsuits pending as of
December 31, 1993, as well as the number of lawsuits filed in 1993, has
declined significantly.
 
  Many of the suits and claims have been settled. In those suits that remain
pending, direct defense costs are being paid by either insurance carriers,
under reservations of rights agreements, or out of insurance proceeds. Two
actions have proceeded to trial against Hoover and resulted in jury verdicts
against it. In one of these actions, judgment was entered in Hoover's favor by
the court after a jury verdict against it and the plaintiff's petition to
appeal from the judgment entered in Hoover's favor has been denied. Hoover is
appealing the other judgment and believes that it has meritorious grounds for
overturning it in whole or in part. Certain
 
                                       6
<PAGE>
 
carriers have brought actions challenging coverage. Hoover and Ply Gem believe
they have meritorious claims for coverage, are defending these actions, have
counterclaimed and are seeking declaratory judgments confirming coverage. Many
of the coverage claims have been settled and proceeds from those settlements,
along with the proceeds from a settlement of claims by Hoover against certain
suppliers of materials used by it in the production of treated wood, are
available for the settlement of the underlying property damage actions,
including the jury verdict now on appeal. Hoover believes that its remaining
coverage disputes will be resolved and a substantial amount of additional
coverage will be available to it.
 
  Hoover and Ply Gem are vigorously defending those lawsuits which cannot be
resolved on a reasonable basis and believe that they have meritorious defenses
to those suits including, in the case of Ply Gem, the defense that it has been
improperly joined, as it did not manufacture or market the Hoover products at
issue, and is not legally liable for the damage allegedly caused by them.
 
  In evaluating the effect of the lawsuits, a number of factors have been
considered, including: the number and exposure posed by the pending lawsuits;
the significant decline in the number of lawsuits filed in 1993; the
availability of various legal defenses, including statutes of limitation, the
existence of settlement protocols, an agreement indemnifying Hoover as to
certain past and future claims and Hoover's experience in settling with its
insurance companies and the likely availability of additional insurance. It is
estimated that the future cost of resolving those matters not presently covered
by existing settlements with insurance carriers and suppliers is sixteen
million dollars, which it expects will be covered by future recoveries from
additional insurance carriers. Based on its evaluation, the Company believes
that the ultimate resolution of the lawsuits and the insurance claims will not
have a material adverse effect upon the financial position of the Company.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.
 
  The following discussion and analysis provides information which management
believes is relevant to an assessment and understanding of the Company's
consolidated results of operations and financial condition. The discussion
should be read in conjunction with the Consolidated Financial Statements and
Notes thereto.
 
RESULTS OF OPERATIONS
 
  NET SALES
 
  The Company achieved record net sales during 1993 of $722.7 million, an
increase of approximately $100 million or 16.0% over 1992 net sales of $623.2
million and an increase of approximately $161 million or 28.7% over 1991 net
sales of $561.6 million. Sales in each of the Company's 1993 quarters were
above those of comparable 1992 periods.
 
  Substantially all operating entities of the Company reported higher net sales
for 1993 when compared with 1992. Of the total net sales increase in 1993,
approximately 10% is attributable to additional unit volume and approximately
6% to increases in average selling prices. The increase in net sales in 1992,
as compared with 1991, was primarily related to additional unit volume.
 
  Strong sales in the Company's Windows, Doors, and Siding group continue to
fuel the Company's growth as this group has achieved double digit sales growth
in each of the last five years.
 
  After several years of decline, due primarily to the closing and
consolidation of certain facilities and elimination of certain lower margin
product lines, Distribution reported substantial improvement in 1993, as net
sales were 19% higher than 1992.
 
  GROSS PROFIT
 
  Gross profit, expressed as a percentage of net sales, was 19.1% in 1993,
compared with 20.7% for 1992 and 21.5% in 1991. Higher raw material costs
(particularly wood and resin), competitive pricing pressures, and costs of
introducing new products accounted for most of the decline in 1993. The lower
margin in 1992 as compared to 1991 was due primarily to higher wood costs.
 
  The Company's results of operations are affected by fluctuations in the
market prices of lumber and other wood products that have been used as raw
materials in its various manufacturing operations. During the last several
years, the market prices of lumber and other wood products have been volatile.
Although the Company attempts to increase the sales price of its products in
response to higher lumber and wood products costs, such sales price increases
often lag behind the escalation in the cost of the raw materials in question.
While the Company intends to increase prices in a timely manner to cover any
further increases in the cost of lumber and other wood products, its ability to
do so may be limited by competitive or other factors.
 
 
                                       8
<PAGE>
 
  The Company continues to explore various strategies to improve its gross
profit margins, including productivity enhancements, increased yields through
more efficient process technologies, cost reduction programs, and reviews of
manufacturing capacity and utilization.
 
  SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
 
  Selling, general and administrative expenses, as a percentage of net sales,
were 14.8% in 1993, compared to 16.3% in 1992 and 16.9% in 1991. The
improvement reflects the Company's continued progress in its ongoing efforts to
manage expense growth relative to revenue growth.
 
  The significant improvement in 1993 and 1992 was primarily due to economies
resulting from the absorption of fixed expenses over a larger sales base.
 
  INCOME FROM OPERATIONS
 
  Income from operations increased 15.5% to $31.6 million in 1993 from $27.4
million in 1992. Income from operations was $25.8 million in 1991. The
improvements are due to the factors discussed above.
 
  INTEREST EXPENSE
 
  Interest expense was $10.1 million in 1993 compared to $9.6 million in 1992
and $14.1 million in 1991. The slight increase during 1993 as compared to 1992
is due primarily to higher average debt balances outstanding during 1993. Lower
interest rates, coupled with lower average debt outstanding during 1992,
favorably affected interest expense in 1992 by $4.5 million as compared to
1991.
 
  In February 1994, the Company refinanced substantially all of its bank debt,
as more fully explained in Note 7 to the Consolidated Financial Statements and
in the Liquidity and Capital Resources discussion below. Pricing under the new
credit facility is expected to be substantially similar to pricing under the
prior facilities.
 
  In March 1994, as more fully explained in Note 8 to the Consolidated
Financial Statements, holders of the Company's 10% Convertible Senior
Subordinated Discount Debentures ("Debentures") converted a total principal
amount of approximately $50 million into 2,751,349 shares of the Company's
common stock. As a result of this transaction, the Company will save, on an
annual basis, $5 million of interest costs.
 
  OTHER INCOME (EXPENSE)
 
  Other income (expense) for 1993 and 1992 primarily includes the costs
associated with the sale of receivables program, partially offset in 1993 by a
gain resulting from an involuntary conversion of property.
 
  INCOME TAXES
 
  The effective income tax rate was 44.8% in 1993, 44.6% in 1992, and 47.9% in
1991. During 1993 the federal statutory rate was increased by 1% retroactive to
January 1, 1993. The rate increase was offset by a proportionately lower amount
of non-deductible goodwill amortization in 1993 as compared to income before
taxes in 1992 and 1991. The higher tax rate in 1991 is primarily due to
operating losses of the Distribution subsidiaries for which no state tax
benefits were available.
 
  NET INCOME
 
  Net income advanced 53% to $9.7 million in 1993 from $6.3 million in 1992.
Net income was $4.0 million in 1991. The factors cited above were responsible
for the significantly improved results of the Company.
 
  The results for 1993 featured a strong operating performance by the Company's
business groups. The Company's continuing success in the home improvement
industry is primarily attributable to an uncompromising emphasis on quality,
excellence in customer service, and superior product design.
 
                                       9

LIQUIDITY AND CAPITAL RESOURCES
 
  The Company's financial position remained strong in 1993.
 
  In February 1994, the Company entered into a five-year revolving credit
facility ("Credit Facility") with a syndicate of banks, which provides
financing of up to $200 million. Initial borrowings were used to repay amounts
outstanding under the Company's previous credit facilities. The Credit Facility
provides the Company with financing at competitive prices, strengthens its
balance sheet by extending debt maturities to 1999, and makes available
additional resources for its Teamwork 90s internal growth programs. See Note 7
to the Consolidated Financial Statements for additional information concerning
the Credit Facility.
 
  As discussed above, holders of the Debentures converted a total principal
amount of approximately $50 million into 2,751,349 shares of the Company's
common stock. As a result, the Company's net worth will be increased by
approximately $50 million, and the Company will save $5 million of annual
interest expense.
 
  The table below summarizes the Company's cash flow from operating, investing,
and financing activities as reflected in the Consolidated Statement of Cash
Flows.

</TABLE>
 
  OPERATING ACTIVITIES
 
  The amount of cash provided by operating activities in 1993 was relatively
unchanged from 1992. The significant increase in 1991 in cash from operating
activities as compared to 1992 resulted from the proceeds from the sale of
certain accounts receivable to a financial institution and to the success of
the Company's inventory reduction program.
 
  The Company's working capital requirements for inventory and receivables are
impacted by changes in raw materials costs, the availability of raw materials,
growth of the Company's businesses and seasonality. As a result, such
requirements may fluctuate significantly.
 
  INVESTING ACTIVITIES
 
  Investing activities of the Company during the discussion periods primarily
consist of the acquisition and sale of property, plant and equipment and the
receipt and usage of funds held for construction.
 
  During 1992, Variform began construction of a new vinyl siding facility in
Jasper, Tennessee and Great Lakes commenced a plant expansion at its facility
in Toledo, Ohio. Aggregate construction and initial production equipment costs,
which are being financed from the proceeds of industrial revenue bonds, are
$11.2 million. The Jasper facility was completed during the second quarter of
1993 and the Toledo facility during the third quarter of 1993.
 
  Capital expenditures (excluding approximately $9.6 million of costs incurred
through December 31, 1993, of which $4.8 million was incurred during 1993 for
the aforementioned construction projects) were $15.7 million in 1993, compared
to $12.3 million in 1992 and $9.7 million in 1991. Most of the outlays were for
machinery and equipment used to expand capacity and improve productivity.
 
  Funds Held for Construction relate to proceeds and usage of cash from the
industrial development revenue obligations discussed above.
 
                                       10
<PAGE>
 
  Fixed asset acquisitions provide a basis for future growth. The Company has
formalized an intensive review procedure for all capital expenditures. The
acceptability of a capital project is based on many factors, including its
discounted cash flow return on investment and projected payback period. The
Company expects to incur approximately $15 million in 1994 for capital
expenditures, excluding costs related to the construction projects discussed
above.
 
  FINANCING ACTIVITIES
 
  During 1993 the Company had borrowings of $ 34.8 million under its revolving
credit lines. Bank borrowings were primarily used to finance growth in working
capital and capital expenditures.
 
BALANCE SHEET CONTINUES TO BE STRONG
 
  The pro forma capitalization of the Company (long-term debt plus
stockholders' equity) was $277.5 million at December 31, 1993. The pro forma
ratio of debt to capitalization was approximately 36% at December 31, 1993
which is substantially improved from such ratio at December 31, 1992 which was
approximately 50%.
 
  The current ratio was 3.2 at December 31, 1993, significantly better than the
2.3 ratio at the end of 1992. The factors that contributed to this improvement
included the reduction of current debt obligations resulting from the Credit
Facility, increased cash balances and higher receivables caused by increased
sales. Cash and marketable securities totaled $14.4 million at December 31,
1993.
 
  Long-term bank debt at December 31, 1993 was $92.9 million, compared with
$62.5 million at December 31, 1992. The higher debt level was needed to finance
higher working capital requirements and capital expenditures.
 
  In addition to cash from operating activities, the Company has a new Credit
Facility available to meet future liquidity needs. After repayment of the prior
credit facilities, approximately $63 million was available for borrowing under
the Credit Facility. The Company has several interest rate agreements which
reduce the Company's exposure to rising interest rates.
 
SEASONAL NATURE OF BUSINESS
 
  The home improvement business is seasonal, particularly in the Northeast and
Midwest regions of the United States where inclement weather during the winter
months usually reduces the level of building and remodeling activity in both
the home improvement and new construction markets. The Company's lowest sales
levels usually occur during the first and fourth quarters. Since a high
percentage of the Company's manufacturing overhead and operating expenses are
relatively fixed throughout the year, operating income tends to be lower in
quarters with lower sales. Inventory and borrowings to satisfy working capital
requirements are usually at their highest level during the second and third
quarters.
 
PROSPECTIVE FINANCIAL STANDARDS
 
  The Financial Accounting Standards Board (FASB) issued Statement No. 115,
Accounting for Certain Investments in Debt and Equity Securities, and FASB No.
112, Employers' Accounting for Postemployment Benefits, which are effective
January 1, 1994. Adoption of these standards is not expected to have a material
impact on the Company's results of operations or financial position, nor will
it affect the Company's cash flows.

Board of Directors and Stockholders
 Ply Gem Industries, Inc.
 
  We have audited the accompanying consolidated balance sheets of Ply Gem
Industries, Inc. and Subsidiaries (the "Company") as of December 31, 1993 and
1992, and the related consolidated statements of income, stockholders' equity,
and cash flows for each of the three years in the period ended December 31,
1993. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Ply Gem
Industries, Inc. and Subsidiaries as of December 31, 1993 and 1992, and the
consolidated results of their operations and their consolidated cash flows for
each of the three years in the period ended December 31, 1993, in conformity
with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Principles of Consolidation
 
  The consolidated financial statements include the accounts of Ply Gem
Industries, Inc. and its wholly-owned subsidiaries after eliminating all
significant intercompany accounts and transactions. Certain prior year items
have been reclassified to conform to the 1993 presentation.
 
 Cash and Cash Equivalents
 
  Cash and cash equivalents include cash on hand and temporary investments
having a maturity of three months or less.
 
 Marketable Securities
 
  Marketable securities are carried at the lower of aggregate cost or market.
 
 Inventories
 
  Inventories are stated at the lower of cost or market. Cost is determined on
the first-in, first-out (FIFO) method.
 
 Property, Plant and Equipment
 
  Owned property, plant and equipment are depreciated, generally on a straight-
line basis over their estimated useful lives. Leasehold improvements are
amortized on a straight-line basis over their respective lives or the terms of
the applicable leases, including expected renewal options, whichever is
shorter. Accelerated depreciation methods are used for tax purposes.
Capitalized leases are amortized on a straight-line basis over the terms of the
leases or their economic useful lives.
 
 Intangible Assets
 
  (a) Patents and Trademarks
 
  Purchased patents and trademarks are recorded at appraised value at time of
acquisition and are being amortized on a straight-line basis over their
estimated remaining economic lives; thirteen to sixteen years for patents and
thirty years for trademarks.
 
  (b) Other Intangibles
 
  Cost in excess of net assets acquired is being amortized from twenty to
thirty years on a straight-line basis and is evaluated annually to determine
potential impairment by comparing its carrying value to the estimated future
cash flows of the related assets. Other purchased intangibles are being
amortized on a straight-line basis generally from ten to thirty-nine years.
 
 Income Taxes
 
  Deferred income taxes are provided to reflect temporary differences between
the financial reporting basis and the tax basis of the Company's assets and
liabilities.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 Earnings Per Share
 
  Earnings per share of common stock are based on the weighted average number
of shares and common equivalent shares outstanding during each of the periods.
Primary and fully diluted earnings per share include the dilutive effect of
unexercised stock options as modified for options in excess of 20% of shares
outstanding. The assumed conversion of the Company's Convertible Subordinated
Debentures was not used in the fully diluted calculation because the result
would be anti-dilutive.

- --------
(a) At the Company's option, interest rates are at the prevailing prime rate
    and various LIBOR rates, or combinations thereof. The Company has entered
    into interest rate cap agreements which limit the maximum interest rates on
    a portion of these loans.
 
  On February 24, 1994 the Company refinanced substantially all of its bank
debt under a $200 million five year syndicated bank credit facility which
replaced several separate bank agreements including short-term facilities.
Accordingly, the table above reflects this transaction as of December 31, 1993.
The loan agreement requires the attainment of certain working capital and
tangible net worth levels and the maintenance of various financial ratios,
among its provisions. Borrowings under this agreement are collateralized by the
common stock of the Company's principal subsidiaries. Under the most
restrictive of these covenants, at December 31, 1993 approximately $2,192,000
was available for the payment of dividends in 1994.
 
  Future maturities of long-term debt, for the years 1995 through 1998 are:
1995--$430,000; 1996--$405,000; 1997--$425,000; and 1998--$448,000.
 
  The net book value of property, plant and equipment pledged as collateral
under mortgages and industrial revenue bonds approximated $6,688,000 at
December 31, 1993.

principal amount of 10% Convertible Senior Subordinated Discount Debentures,
due October 1, 2008, exchanged them for 2,751,349 shares of common stock of the
Company. The remaining $37,000 of the original $50 million face amount was
redeemed by the Company. The pro forma unaudited consolidated balance sheet
reflects this event as of December 31, 1993, including estimated costs. If this
transaction had occurred on January 1, 1993 primary and fully diluted earnings
per share for 1993 would have been $.84 and $.83, respectively.

NOTE 10 -- RETIREMENT PLANS
 
  The Company provides retirement benefits to certain of its salaried and
hourly employees through non-contributory defined benefit pension plans. The
benefits provided are primarily based upon length of service and compensation,
as defined. The Company funds the plans in amounts as actuarially determined
and to the extent deductible for Federal income tax purposes. Plan assets
consist primarily of investments in mutual funds and unallocated general
accounts of guaranteed income contracts.
 
  The components of pension expense are as follows:

NOTE 11 -- STOCK OPTION PLANS
 
  The Company's Executive Incentive Stock Option Plan provides for the granting
of options to key employees to purchase up to 2,037,500 shares of common stock.
Option prices must be 100% of fair market value at date of grant except for an
employee who owns in excess of 10% of the common stock outstanding, in which
case the exercise price is 110% of the fair market value at date of grant.
Options are exercisable in full or in part after one year from the date of
grant and expire within ten years (within five years for an employee owning in
excess of 10% of the outstanding common stock). Shares acquired must be held
for one year.
 
  The Senior Executive Stock Option Plan ("the Senior Plan") authorizes the
granting of either incentive or non-qualified stock options only to executives
of businesses acquired by the Company or to newly employed executives. The
Senior Plan provides for 750,000 shares of the Company's common stock to be
reserved for issuance.
 
  The 1989 Employee Incentive Stock Plan ("the 1989 Plan") authorizes the
granting of incentive and non-qualified stock options and awards of restricted
stock and is to be made available to executives and key employees of the
Company. As in the Senior Plan, option terms and holding and exercise periods
may vary except that no option may be exercised more than ten years after date
of grant. Stock awarded under the Plan will be subject to restrictions as to
sale or transfer. These restriction may lapse or be waived based on
performance, period of service or other factors. The 1989 Plan provides for
3,500,000 shares of the Company's common stock to be reserved for issuance.

  In 1991, the Company granted 250,000 shares of restricted stock to an
executive officer of the Company. The restrictions of these shares will be
released at the rate of 25,000 shares per year upon the attainment of certain
profit goals and the continued employment of the officer. The restrictions will
be lifted in the event of a change in control of the Company. The unamortized
restricted stock resulting from this stock award has been deducted from
stockholders' equity and is being written off over ten years at the fair market
value on the dates the restrictions are lifted.

HOOVER TREATED WOOD PRODUCTS, INC. ("HOOVER")
 
  Hoover, a wholly-owned subsidiary of the Company, is a defendant, along with
many other parties, in a number of commercial lawsuits, including a purported
class action on behalf of certain Maryland homeowners, alleging property damage
caused by alleged defects in certain pressure treated interior wood products it
produced and sold through August, 1988. The Company is also a defendant in many
of these suits. The number of lawsuits pending as of December 31, 1993, as well
as the number of lawsuits filed in 1993, has declined significantly.
 
  Many of the suits and claims have been settled. In those suits that remain
pending, direct defense costs are being paid by either insurance carriers,
under reservations of rights agreements, or out of insurance proceeds. Two
actions have proceeded to trial against Hoover and resulted in jury verdicts
against it. In one of these actions, judgment was entered in Hoover's favor by
the court after a jury verdict against it and the plaintiff's petition to
appeal from the judgment entered in Hoover's favor has been denied. Hoover is
appealing the other judgment and believes that it has meritorious grounds for
overturning it in whole or in part. Certain carriers have brought actions
challenging coverage. Hoover and the Company believe they have meritorious
claims for coverage, are defending these actions, have counterclaimed and are
seeking declaratory judgments confirming coverage. Many of the coverage claims
have been settled and proceeds from those settlements, along with the proceeds
from a settlement of claims by Hoover against certain suppliers of materials
used by it in the production of treated wood, are available for the settlement
of the underlying property damage actions, including the jury verdict now on
appeal. Hoover believes that its remaining coverage disputes will be resolved
and a substantial amount of additional coverage will be available to it.
 
  Hoover and the Company are vigorously defending those lawsuits which cannot
be resolved on a reasonable basis and believe that they have meritorious
defenses to those suits including, in the case of the Company, the defense that
it has been improperly joined, as it did not manufacture or market the Hoover
products at issue, and is not legally liable for the damage allegedly caused by
them.
 
  In evaluating the effect of the lawsuits, the Company has considered a number
of factors, including: the number and exposure posed by the pending lawsuits;
the significant decline in the number of lawsuits filed in

1993; the availability of various legal defenses, including statutes of
limitation, the existence of settlement protocols, an agreement indemnifying
Hoover as to certain past and future claims and Hoover's experience in settling
with its insurance companies and the likely availability of additional
insurance. The Company estimates that the future cost of resolving those
matters not presently covered by existing settlements with insurance carriers
and suppliers is sixteen million dollars, which it expects will be covered by
future recoveries from additional insurance carriers. Based on its evaluation,
the Company believes that the ultimate resolution of the lawsuits and the
insurance claims will not have a material adverse effect upon the financial
position of the Company.
 
EXECUTIVE COMPENSATION
 
  In the event of a change in control of the Company, as defined in resolutions
adopted by the Board of Directors, senior management, except for the chairman,
have the right to receive payments upon termination of employment or
resignation within one year. Such payments are to be 2.75 times average annual
compensation, as defined, plus 2.75 times the difference between the market and
exercise price of any unexercised incentive stock options. At December 31,
1993, the maximum amount payable, applicable to twenty-five individuals, would
be approximately $14,783,000 attributable to compensation and $15,248,000 to
the options.
 
LETTERS OF CREDIT
 
  At December 31, 1993 $22,580,000 of letters of credit issued by the Company's
banks were outstanding, principally in connection with certain financing
transactions.
 
OTHER
 
  The Company and its subsidiaries are subject to legal actions from time to
time which have arisen in the ordinary course of its business. In the opinion
of management, the resolution of these claims will not have a material adverse
effect upon the financial position of the Company.
 
NOTE 13 -- INDUSTRY SEGMENT
 
  The Company operates predominantly in one business segment. Operations in the
Home Improvement Products Business consist of the manufacture and sale of
exterior vinyl siding, wood and vinyl-framed windows and patio doors,
prefinished decorative plywood and solid wood paneling, furniture components
and various pressure-treated wood products and the purchase and resale of a
variety of other products for the home improvement and industrial markets. One

ended December 31, 1993 and December 31, 1992, respectively.

     10. Conflicting Agreements.  The Employee hereby represents and warrants 
         ----------------------
to the Employer that (a) neither the execution of this Agreement by the 
Employee nor the performance by the Employee of any of the obligations or 
duties of the Employee under this Agreement will conflict with or violate or 
constitute a breach of the terms of any employment or other agreement to which
the Employee is a party or by which the Employee is bound, and (b) the 
Employee is not required to obtain the consent of any person, firm, 
corporation or other entity in order to enter into this Agreement or to 
perform any of the obligations or duties of the Employee hereunder.

     11. Inventions, Discoveries, Etc.  The Employee hereby assigns, and shall
         ----------------------------
promptly and fully disclose and

                                     -8-

<PAGE>
 
assign to the Employer, any and all inventions, discoveries, improvements, 
developments, concepts and ideas which relate to any activities of the 
Employer or any of the subsidiaries or affiliates of the Employer, whether or 
not patentable and whether or not conceived, developed or reduced to practice 
by the Employee alone or by himself and others, or both, during the period of 
his employment with the Employer or with any affiliate or subsidiary of the 
Employer.

         12. Non-Disclosure of Confidential Information and Non-Competition.
             --------------------------------------------------------------

             (a)  The Employee acknowledges that it is the policy of the 
Employer to maintain as secret and confidential all valuable and unique 
information and other information required by the Employer as confidential 
heretofore or hereafter acquired, developed or used by the Employer or any 
affiliate or subsidiary of the Employer relating to the business, operations, 
employees, suppliers and customers of the Employer and of the subsidiaries and
affiliates of the Employer (all such information is hereinafter referred to as
"Confidential Information"). The parties recognize that the services to be 
performed by the Employee pursuant to this Agreement are special and unique, 
and that by reason of his employment by the Employer prior to the date hereof 
after the date hereof, the Employee has acquired and will acquire Confidential
Information. The Employee recognizes that all such Confidential Information is
the property of the Employer and

                                     -9-

<PAGE>
 
its subsidiaries and affiliates. In consideration of the Employee's employment
with the Employer pursuant to this Agreement, the Employee agrees that:

             (i)  except as required by the duties of his employment, without 
         the prior written consent of the Board of Directors of the Employer,
         the Employee shall never, directly or indirectly, either during or
         after the Employment Term, use, publish, disseminate or otherwise
         disclose any Confidential Information obtained, whether prior or
         subsequent to the date hereof, during his employment with the
         Employer or any affiliate or subsidiary of the Employer;

             (ii) both during and after the Employment Term, the Employee 
         shall exercise all due and diligent precautions to protect the 
         integrity of the business plans, customer lists, statistical data and
         compilations, agreements, contracts, manuals or other documents of 
         the Employer and its subsidiaries and affiliates which embody any 
         Confidential Information, and upon the expiration or termination of 
         the Employment Term, the Employee shall return to the Employer and its 
         subsidiaries and affiliates all such documents (and copies thereof) 
         which are in the possession or under the control of the Employee.

The Employee agrees that the provisions of this Paragraph (a) are reasonably 
necessary to protect the proprietary rights of 

                                    -10-

<PAGE>
 
the Employer and the subsidiaries and affiliates of the Employer in the 
Confidential Information and their trade secrets, goodwill and reputation.

         (b)  During his employment with the Employer and for a period of 
three (3) years after the expiration or termination, for any reason 
whatsoever, of the Employment Term, the Employee shall not, in any manner, be 
engaged, directly or indirectly, within the States of Arizona, Colorado, New 
Mexico or Texas, or any other geographic area for which Employee has 
significant sales, marketing or other responsibilities for Employer, Hoover, 
Ply-Gem or their Affiliates during the aforesaid three-year period (or for 
such lesser period of time or for such lesser geographical area as may be 
determined by a court of law or equity to be a reasonable limitation on the 
competitive activities of the Employee) as an employee, partner, officer, 
director, owner, representative, consultant, agent or stockholder of any 
corporation, partnership, proprietorship or other form of business entity, 
other than the Employer, (1) which is engaged in any business which is or was 
competitive with any business conducted by the Employer or by any subsidiary 
or affiliate of the Employer; or (2) which manufactures or distributes any 
products similar to those which were manufactured or distributed at any time 
during the Employment Term either by the Employer or by any subsidiary or 
affiliate of the Employer. The Employee shall not, either during the 
Employment Term or for a period of three (3) years

                                    -11-

<PAGE>
 
after the expiration or termination, for any reason whatsoever, of the 
Employment Term, other than in his capacity as an employee of the Employer, 
(i) seek to persuade any director, officer or employee of the Employer or any 
subsidiary or affiliate of the Employer to discontinue that individual's 
status or employment with the Employer or any such subsidiary or affiliate of 
the Employer or to become employed in any activity similar to or competitive 
with the activities of the Employer or any subsidiary of affiliate of the 
Employer; (ii) hire or retain any such person at any time within twelve (12) 
months following the date of cessation of employment of such person with the 
Employer or any subsidiary or affiliate of the Employer; or (iii) solicit (or 
cause or authorize), directly or indirectly, to be solicited, for or on behalf
of himself or any third party, any business from others who were, at any time 
within five (5) years prior to the expiration or termination of the Employment
Term, customers of the Employer or any subsidiary or affiliate of the 
Employer. The Employer and the Employee acknowledge that nothing contained in 
this Section 12 shall prohibit the Employee from acquiring equity securities of
a publicly held company engaged in the activities specified in (i) above which
in the aggregate do not exceed 5% of the equity securities of such publicly 
held company, or a greater percentage if the activities specified in (i) above
constitute an insubstantial part of the business of such publicly held 
company.

                                    -12-

<PAGE>
 
         (c)  The provisions of this Section 12 shall survive the termination 
or expiration of the Employment Term.

     13. The Company's Right to Injunctive Relief.  The Employee acknowledges 
         ----------------------------------------
that the services to be rendered by the Employee to the Employer are of a 
unique character which gives them a special value to the Employer and its 
subsidiaries and affiliates. The Employee further acknowledges that any breach
or threatened breach by the Employee of any of the provisions of Section 11 or
Section 12 hereof will result in irreparable and continuing harm to the 
Employer and its subsidiaries and affiliates for which the Employer and its 
subsidiaries and affiliates would have no adequate remedy at law. Therefore, 
in addition to any other remedy which the Employer and its subsidiaries and 
affiliates may have at law or in equity, the Employer and its subsidiaries and
affiliates shall be entitled to injunctive relief or other equitable remedies 
in the event of any such breach or threatened breach.

     14. Invalidity of Covenants.  The parties acknowledge that the laws and 
         -----------------------
public policies of the various states of the United States and the District of
Columbia may differ as to the validity and enforceability of the covenants 
contained in Section 12. It is the intention of the parties that activities of
Employee be restricted only to the extent necessary for the protection of 
legitimate business interests of Employer, that the provisions of this 
paragraph shall, to the fullest extent

                                    -13-

<PAGE>
 
permissible under the law and public policy, be enforced by the courts of each
state and jurisdiction in which enforcement is sought, and that the 
unenforceable (or the modification necessary to conform the covenants 
contained in Section 12 with such law and public policy) part of Section 12 
shall be adjudicated to be invalid or unenforceable without affecting any 
other part of Section 12. Accordingly, if any part of Section 12 shall be 
adjudicated to be invalid or unenforceable in any action or proceeding in 
which Employee, or Employee's heirs, executors or administrators and Employer,
its successors or assigns, are parties, whether in its entirety or as modified
as to duration, territory or to otherwise, then such part shall be deemed 
modified so as to be enforceable or, if required, deleted from the Agreement 
or amended, as the case may be, in order to render the remainder of Section 12
valid and enforceable. Any such deletion or amendment shall apply only where 
the court rendering the same has jurisdiction. The invalidity or 
unenforceability of any particular provision of this Agreement shall not 
affect the other provisions hereof, and this Agreement shall be construed in 
all respects as if such invalid or unenforceable provision were omitted.

     15. Signing Bonus.  (a)  In consideration of the Employee's execution of 
         -------------
this Agreement, the Employee shall receive from the Employer by check or wire 
transfer, an amount equal to thirty-three and 34/100 percent (33.34%) of the 
income

                                    -14-
<PAGE>
 
before taxes, cumulative effect of changes in accounting principles and 
extraordinary items of the Employer during the period October 1, 1987 through 
December 31, 1987 determined as set forth in paragraph (b) below, which shall 
be paid to Kruse within ten (10) days after determination pursuant to 
paragraph (b). For purposes of this paragraph, calculation of income before 
taxes shall not include a deduction for the payment of the signing bonus 
payable hereunder or the signing bonus payable to Gordon K. Runyon pursuant to 
his employment agreement with the Company.

         (b)  On or before February 29, 1988 the Employer shall have had the 
independent certified public accountants for the Employer, Ernst & Whinney 
("E&W"), prepare a financial statement of the Employer for the three months 
ending December 31, 1987 (the "December 1987 Interim Financial Statements") 
and prepare a review report thereon. Such statement shall have been prepared 
in accordance with generally accepted accounting principles applied on a basis
consistent with the 1987 Financial Statements and such review shall have been 
performed in accordance with standards established by the American Institute 
of Certified Public Accountants. Upon the conclusion of such review, E&W shall
have delivered its review report (the "Auditor's Report") to Hoover, the 
Employer and the Employee to the effect that their examination of the December
1987 Interim Financial Statements was made in accordance with generally

                                    -15-

<PAGE>
 
accepted auditing standards and that they are not aware of any
material modifications that should be made to the December 1987 Interim  
Financial Statements in order for them to be in accordance with generally 
accepted accounting principles. 
     Hoover shall have had the right, through its own personnel or its own 
independent certified public accountants, and at its own expense, to consult  
with E&W, review their work papers and all memoranda in connection with 
such review and familiarize themselves with the performance of the review. In 
the event that Hoover does not agree with the determination of income before 
taxes, cumulative effect of changes in accounting principles and extraordinary
items, Hoover shall, within seven (7) business days after the date on which the
December 1987 Interim Financial Statements are furnished to Hoover, deliver 
to the Employer or the Employee a letter stating the specific respects in 
which Hoover disagrees with such determination. Hoover, the Employer 
represented by its stockholder Hoover, and the Employee shall then consult to 
resolve the matters in dispute and, if necessary, the determination shall be 
revised to reflect such resolution. If, within five (5) business days after 
the expiration of said 7-day period, Hoover and the Employee are unable to 
resolve the matters in dispute, Hoover shall retain, at Hoover's expense, a 
certified public accounting firm of national standing ("Hoover's Accountants")
to review the determination by E&W. In the event E&W and



                                    -16-





<PAGE>
 
Hoover's Accountants have not resolved the matters in dispute within ten (10)
calendar days after the expiration of said 5-day period, such matters shall be
submitted to an independent accounting firm of recognized national standing, 
whose decision as to such matters shall be conclusive and binding upon the 
parties.  Such independent accounting firm shall be selected by Hoover's 
Accountants and E&W within two (2) business days after the expiration of said
10-day period, but if they are unable to agree on such an independent
accounting firm within said 2-day period, such firm shall be chosen by lot
from among the so-called "Big-Eight" accounting firms (other than any
accounting firm which has served Ply-Gem, Hoover or the Employer since January
1, 1982). Each party shall pay the fees and expenses of its own auditors under
this paragraph (b), but as to E&W, only those expenses incurred in resolving
any disagreement over its initial determination of income before taxes and
extraordinary items (the cost of the initial review to be borne by the
Employer) and one-half of the fees and expenses of any third independent
accounting firm, if required.

     16. Notices.  Any notice, request, information or other document to be 
         -------
given under this Agreement to any party hereunder by any other party hereunder

certified mail, postage prepaid to the following addresses:

     (b)   For purposes of calculating the amount to be paid into the Pool for 
a Bonus Period (the "Pool Amount") the income before taxes, cumulative effect 
of changes in accounting principles and extraordinary items of the Company 
will be determined in conformity with generally accepted accounting principles
applied consistently with those used in preparing the September 30, 1987

Company, its shareholders and Hoover Treated Wood Products, Inc. ("Hoover"), 
dated February 1, 1988 (the "Stock Purchase Agreement")) of the company except

without limitation, real property and equipment, shall be excluded; (2) no 
charge shall be made for (A) amortization of any goodwill occasioned by the 
transaction contemplated by the Stock Purchase Agreement, (B) depreciation of
fixed assets of the Company in excess of (x) depreciation on the actual cost 
of assets acquired after the Closing Date under the Stock Purchase Agreement and
(y) depreciation that would be taken on assets owned by the Company on such 
Closing Date based on the method of depreciation used by the Company for the 
fiscal year ended September 30, 1987, (C) overhead, management or similar

profit sharing, employee stock ownership plan contributions, pension 
contributions and other employee benefits and all other expenses which are 
paid or accrued by the Parent Group for or on behalf of the Company; (D) bonus
payments made or accrued pursuant to this Management Bonus Pool Plan; (E) 
payments made or accrued by Kruse and Runyon pursuant to respective Agreements
Not To Compete dated as of February __, 1988 with Hoover; and (F) Signing 
Bonus payments made to Kruse and Runyon pursuant to respective Employment 
Agreements dated as of February __, 1988 with the Company; and (3) interest 
expense shall not include interest expense paid or accrued by the Parent Group
for the purchase of shares of the Company, but shall include any interest 
expense paid or accrued by or on behalf of the Company for any of the 
following purposes:  (A) interest on indebtedness incurred by the Company in 
the ordinary course of business or to acquire assets for use in the business 
of the Company; (B) interest at the working capital rate charged by the Parent
Group to members of the Parent Group other than the Company on advances made 
by the Parent Group to the Company; and (C) working capital charges by the 
Parent Group to the Company at the same rates charged by members of the Parent
Group to members of the Parent Group other than the Company.  The Company 
shall cause its pre-tax income to be timely determined by the independent 
certified public accountants (the "Accountant") retained by Ply-Gem to audit 
the


                                     -3-
<PAGE>
 
consolidated financial statements of the Parent Group for each Bonus Period.  
Such report of the Accountant, so long as made in good faith and absent 
manifest error, shall represent the final determination of the pre-tax income 
of the Company and shall be valid and binding upon the Company and the 
employees of the Company.

         (c)  For each Bonus Period, the Allocator (as such term is defined in
this paragraph (c)) shall determine in his sole discretion, which, if any, of 
the Company's management employees, which may include the Allocator, shall 
receive bonuses from the Pool and the amount of such bonuses.  To be eligible 
for any payment hereunder, a management employee of the Company, including 
the Allocator, must be employed by the Company on the last day of the 
applicable Bonus Period, unless the employee's termination during such Bonus 
Period was due to his death, disability, or retirement after age 62.  The 
"Allocator", as such term is used herein, shall mean the President of the 
Company in office at the end of any Bonus Period.

         (d)  The Pool Amount shall be determined utilizing the amount 
reported as "Income Before Taxes and Extraordinary Items" in the Accountant's 
Report (as defined in Paragraph (e)) for each Bonus Period, and the Board of 
Directors of the Company shall cause the Pool Amount for each such Bonus 
Period to be determined no later than ninety (90) days following the 

                                     -4-
<PAGE>
 
end of such Bonus Period. Within ten (10) days after the Allocator is notified
by the Board of Directors of the Company (the "Board") of the final 
determination of the Pool Amount, the Allocator shall give the Board written 
notice of the employees selected by the Allocator to receive a bonus from the 
Pool and the amount of each bonus (the "Bonus List"). The Company shall 
distribute such bonus payments immediately after the Board receives and 
approves the Bonus List. The bonus payments shall be made in a single cash 
payment to each recipient unless the Board and a bonus recipient have 
otherwise previously agreed in writing. 
     (e)   Until December 31, 1992, the Parent Group shall maintain separate 
unconsolidated books and records for the Company, for internal review 
purposes, and will, for a sixty (60) day period following each fiscal year end
of the Company, make such books and records reasonably available for 
inspection by the Allocator and any accounting firm selected by the Allocator 
whose fees shall be paid by the Allocator. The Company's Income Before Taxes 
and Extraordinary Items shall be timely determined and reported by the 
Accountant. The Accountant's report (the "Accountant's Report") shall be in 
writing, shall set forth calculations made to reach the determination of the 
Company's Income Before Taxes and Extraordinary Items, the manner in which the
determination was made and an opinion that the audit of Ply-Gem's consolidated
 



                                     -5-





<PAGE>
 
financial statements was performed in accordance with generally accepted 
audited standards and that as a result of such audit and the audit procedures 
performed on the separate unconsolidated books and records of the Company, 
nothing came to the Accountant's attention which indicates that the 
calculation of the Company's Income Before Taxes and Extraordinary Items was 
not performed in accordance with the terms contained herein.  Failure of the 
Allocator to object to the Accountant's Report within thirty (30) days shall 
be conclusive acceptance thereof for all purposes.

forth and for other good and valuable consideration, the parties hereto have 
agreed and do hereby agree as follows:

     1.  Grant of Options.  The Company hereby grants to Kruse the right and 
         ----------------
option (hereinafter referred to as the
<PAGE>
 
"Option") to purchase all or any part of an aggregate of 20,000 shares of the

     4.  Adjustments.  In the event of any change in the Common Stock of the 
         -----------
Company by reason of any merger, consolidation, recapitalization, 
reclassification, stock split, combination of shares or dividend  payable in 
Common Stock of the Company (in excess of five (5%) percent thereof) after the

Board of Directors of the Company as provided in this paragraph 4 shall be 
conclusive as long as such adjustments shall be made in the same manner to all
similar outstanding options of the Company.

     5.  Exercise of Option.  Subject to the terms and conditions of this 
         ------------------
Option Agreement, the option may be exercised by Kruse, his heirs or assigns

<PAGE>
 

full purchase price of such shares by certified check payable to the Company.

6) after the due and proper exercise of this Option. 

     It is expressly understood that it shall be a condition of the issuance 
and delivery of any stock upon the due and proper exercise of the Option or 
any part thereof that prior to the delivery of the certificate or 
certificates as to which the Option shall have been so exercised as aforesaid,
Kruse (or anyone acting under him or his heirs or designs, as the case may be)

Securities Act of 1933, as amended (the "Securities Act"), or any rules and 
regulations thereunder. The time of the delivery of such certificate or 
certificates of stock may be postponed by the Company for such period as may 
be

<PAGE>
 
required by the Company to comply with any listing requirements of any 
national securities exchange or to comply with any applicable state or federal
laws.

     The Company shall not be obligated to sell, issue or deliver any shares 
as to which the Option or any part thereof shall have been exercised as 
aforesaid unless the shares with respect to which the Option shall be 
exercised are at that time effectively registered or exempt from registration 
under the Securities Act.

     All shares that shall be purchased upon the exercise of the Option as 
provided herein shall be fully paid and non-assessable.

     6.  Representations of Kruse.  Kruse acknowledges that he is acquiring

exercise thereof without an opinion of counsel to the Company that the Option 
or shares, as the case may be, are exempt from registration under the 
Securities Act or if such shares or options are required to be registered, 
then such shares, assignment or sale shall not be effective prior to such 
registration.  

     7.  No Transfer.  Anything herein to the contrary notwithstanding, this 
         -----------
Option or the rights with respect hereto


                                     -5-

whichever date is later.

     8.  Legend.  Certificates for all Shares acquired upon the exercise of 
         ------ 
the Option shall be inscribed with a legend giving notice of all restrictions 
with respect to such Shares including but not limited to restrictions imposed

agreement between Kruse and the Company with respect thereto.

     9.  Termination.  The Option granted pursuant to this Agreement shall 
         -----------
terminate upon the earlier of (i) the fifth (5th) anniversary of the date of 
this Agreement, or (ii) the material breach by Kruse of the terms of a Stock 
Purchase Agreement dated February 1, 1988, among the Company's subsidiary, 
Hoover Treated Wood Products, Inc. ("Hoover"), Kruse and Gordon K. Runyon or 
the termination of the employment of Kruse under an Employment Agreement dated
as of February 9, 1988 among Kruse and Sagebrush Sales, Inc. (other than a 
termination by Sagebrush without cause), or violation by Kruse of the 
provisions of Section 12 or 13 of such Employment

<PAGE>
 
Agreement, or the material breach by Kruse of the terms of an Agreement Not To
Compete dated February 9, 1988 between Hoover and Kruse.

     NOW, THEREFORE, in consideration of mutual agreements and understandings 
set forth herein, the Company and the Executive hereby agree as follows:

Directors for its required approval and recommend and vote in favor of such 
approval.

2.  Position, Duties, Responsibility.

          --------
as the President and Chief Operating Officer of the Company, with authority

and report and be responsible to the Chairman.  The Executive shall devote all
of his professional time to the business of the Company in order to 
satisfactorily discharge his duties and responsibilities to the Company, 
except for reasonable time spent for trade, civic and charitable activities 
or for service on other boards of directors, subject
<PAGE>
 
to approval as provided in 2(b) below. The Executive  shall report only to 
Jeffrey Silverman, in his capacity as the Chairman, it being the intent of 
the parties that Executive shall be the second ranking officer of the Company 
after the Chairman.

     (b)   Other Activities.  Except upon the prior oral or written consent of
           ----------------
the Chairman, the Executive, during the Term of Employment, shall not (1)
accept any other employment, (ii) serve on the board of directors of other
corporations or (iii) engage, directly or indirectly, as an owner, employee,
officer, advisor, consultant or independent contractor, or otherwise, in any
other business activity that is competitive with activities of the Company or
any affiliated entity, except nothing shall prevent the Executive from making
an investment in a publicly held company as long as the Executive does not own
five percent (5%) or more of the equity interest in such company. Any such
activity referred to in clause (iii) above, whether performed during the Term
of Employment or thereafter, shall be referred to herein as a "Competitive
Activity", Executive agrees that only if his employment shall be terminated
for Cause, or if he shall voluntarily terminate his employment without the
consent of the Company and without Good Reason, then, for the lesser of one
(1) year or the remaining initial term of this Agreement, Executive shall not
engage in any Competitive Activity, provided that, if the Company wishes to
require Executive to comply with the foregoing post-termination restrictive
covenant, the Company shall give written notice thereof to Executive within
ten (10) business days of such termination, and the Company shall continue to
pay Executive during such period of non-competition his base salary then in
effect. "Competitive Activity", after termination of this Agreement, shall not
include Executive's employment by a party, the activities of which are
partially competitive to the Company, if Executive is not directly involved in
such competitive activities. Nothing in this Agreement shall prevent Executive
from serving on the Boards of trade, civic or charitable institutions.

    (c)    Board Member, Other Duties. The Chairman shall nominate and vote for
           --------------------------
the Executive, and the Executive agrees to serve, for no additional 
compensation, as a member of the Board of Directors. However such position 
shall be (i) initially subject to the election of the Executive to such 
position by the duly elected Board of Directors acting within the scope of its
authority and in conformity with the obligations of such Board of Directors to
the Company and its stockholders and (ii) subject to nomination and election 
or re-election in conformity with the Company's By-laws and other charter 
documents and the Delaware General Corporation law. Subject to Section 5(d) 
hereof, the failure of the Executive to be a member of the Board of Directors 
at any time for any reason shall not be considered to be a breach of any 
provision hereof or a termination hereof. Executive further agrees to serve as
an officer or director of such other subsidiaries or affiliates of the Company
as the Chairman shall request, without any additional compensation.

(the "Annual Plan"), the purpose of which will be to reward performance of the
Executive.  One or both of the plans may include other executives of the 
Company.  The foregoing plans will be retroactive in their application to 
Executive to January 1, 1994.       
 
          (i)  The Long Term Plan will consist of three year performance cycles.
               All awards under the plan would be made annually.  Aggressive, 
               but realistically achievable goals for each cycle would be 
               established on an annual basis by the mutual agreement between 
               the Executive and the Chairman.  It is agreed that the Annual 
               Plan and Long Term Plan will generate payment to the Executive
               consistent with performance relative to the mutually agreed upon
               goals for each plan and consistent with major corporate 
               compensation practices and payment guidelines for senior 
               executive positions.

         (ii)  Each year, the Executive and the Chairman will establish 
               aggressive, but realistically achievable operating goals, both
               financial and non-financial, for the following year, in 
               connection with the Annual Plan.  The Executive shall receive 
               minimum bonuses under the Annual Plan of $400,000 for the 
               1994 calendar year, $250,000 for the 1995 calendar year and 
               $250,000 for the 1996 calendar year.      

        (iii)  The Company agrees to determine the amount of the bonus, if 
               any, to which Executive shall be entitled as soon as possible
               after the end of each calendar year, and to pay such bonus
               promptly after such determination.

     (c)  Benefits.  During the Executive's employment hereunder, the Executive
          --------
shall be entitled to participate in any plan, arrangement or policy of the 
Company providing for medical benefits, dental benefits, life insurance, 
disability insurance, vacation time, sick leave and other benefits to the 
extent consistent with Executive's position in the Company.

with his duties, provided such expenses are appropriately vouchered.

     (f)  Relocation.  The parties contemplate that Executive shall be based 
          ----------
at the Company's principal offices in New York City, provided that they shall 
mutually agree on the timing of Executive's relocation.  At the time that the 
Executive is required to relocate in connection with his employment with the 
Company, the Company will provide a relocation package as agreed by the 
Chairman and the Executive.

     (g)  Physical Examination.  The Executive agrees that after the Start 
          --------------------
Date he shall undergo any physical examinations and/or tests required for key 
man, disability and employee benefit life insurance, as are reasonably required
to obtain such insurance.  Executive will make immediately available to the 
Chairman and/or a medical representative of the Company the results of his 
last physical examination.  It is agreed that such information will remain 
confidential.  Executive shall promptly sign any insurance applications 
submitted to enable the Company to obtain Keyman insurance.

4.   Early Resignation by the Executive.
     ----------------------------------

thousand dollars ($1,500,000).

5.   Termination of Employment.

<PAGE>
 
physician for the purpose of conducting a physical or mental examination of 
Executive.  Executive shall cooperate in submitting to such an examination.  
The physician shall render an opinion to the Company and Executive, within 5 
days of said examination and determine whether or not the Executive is capable
of performing his duties and if not, whether Executive shall be capable of 
performing his duties within a period of 180 days.  If such physician's 
written opinion concludes that the Executive shall not be able to resume his 
duties within a period of 180 days and the Executive disagrees with such 
opinion, he shall be free to engage a physician of his own choice for the 
purpose of rendering another opinion with respect to Executive's capacity to 
perform.  Such physician shall render his written opinion to the Executive and
the Company within 5 days.  If Executive's physician disagrees with the 
opinion of the Company's physician, the two physicians together shall choose a
third physician, who in turn will conduct a third examination of Executive to 
determine his capacity to perform his duties under this Agreement.  Such third 
physician shall render his opinion to the Company and the Executive within 5 
days of such examination and such third physician's written opinion shall be 
conclusive and binding upon both the Company and the Executive with respect to
whether the Executive is capable of resuming his duties within a period of 180
days.  The measuring period for the resumption of duties within 180 days shall
commence from the date upon which the Company first gave notice to the 
Executive of its request that he submit to a physical or mental examination 
for the purpose of determining his capacity to perform his duties hereunder.  
The Termination Date shall be the last day of such applicable period.

               other Proprietary Information (as defined below) relating to

               material containing any Proprietary Information (as defined
               below) relating to the business of the Company.

       (ii)    The Executive hereby acknowledges that prior to and for the 
               duration of this Agreement, he has gained and will gain
               knowledge of certain information which is confidential and
               proprietary to the Company (the "Proprietary Information"). Such
               information includes but is not limited to: (A) marketing,
               competitive or other information available only to top
               management of the Company; (B) information pertaining to the
               contracts between the Company and its customers, including the
               identity of the customers, pricing information and contract
               termination dates; (C) any and all other information related to
               the Company of which the Executive may become aware but which is
               not generally known to outsiders, including but not limited to
               cost allocations and other confidential information concerning
               or relating to any of the customers, business or methods of
               operation of the Company; and (D) various trade secrets which

               or will be regularly used in the business of the Company.

       (iii)   The Executive shall not during the Term of Employment or at any
               time thereafter use (other than in the performance of his
               duties to the Company) or disclose to any person, firm,
               corporation, partnership or other entity whatsoever outside the
               Company or to any officer, director, stockholder, partner,
               associate, employee, agent or representative of any thereof
               (except as required by law or with the express prior written
               approval of the Chairman and Chief Executive Officer of the
               Company) any such Proprietary Information either directly or
               indirectly. The foregoing provisions shall not be construed to
               prevent the Executive from making use of or disclosing
               information which is in the public domain through no fault on
               the part of the Executive; however, specific information shall
               not be deemed to be in the public domain merely because it is
               encompassed by some general information that is published or in
               the public domain or in the Executive's prior possession. The
               Company shall be entitled, in addition to any other right and
               remedy it may have, at law or in equity, to seek an injunction,
               enjoining or restraining the Executive from any violation or
               threatened violation of this Section 4(h), and Executive agrees
               and understands that such injunction is a possible remedy.

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

     Unless the Company shall, prior to ninety (90) days before the expiration
of the Term of Employment (including all Renewal Terms, as hereinafter 
defined), notify the Executive in writing of its intention to terminate the 
Term of Employment, the Term of Employment shall be extended for a period of 
one year. Each one year extension shall be referred to as a "Renewal Term." 
Thereafter, the Company shall have the equivalent option, in its sole 
discretion, to terminate the Term of Employment at the end of any Renewal Term
and shall notify the Executive in writing of the Company's intent prior to 
ninety (90) days before the expiration of any Renewal Term. The Executive 
shall have no right, express or implied, to continue his employment after the 
expiration of the Term of Employment or any Renewal Term if the Company

7.   Certain Stock Matters.
     ---------------------

     In addition to the foregoing compensation described in this Agreement, 
upon the start date, the Executive shall be granted the following restricted 
shares and stock options:

     (a)  175,000 shares of the Company's common stock at no cost to 
Executive, pursuant to a Restricted Stock Agreement, the terms of which shall 
provide for the lapsing of the restrictions ratably over a four year term, 
based upon Executive's continued employment by the Company. The Restricted 
Stock Agreement shall be approved and adopted by the Company no later than one
(1) year after Start Date. The Company agrees to cause the Restricted Stock, 
when issued to the Executive, to be registered under the Securities Act and to
use its best efforts to deliver certificates representing the shares of 
Restricted Stock, within three (3) weeks after the lapse of the applicable 
restrictions.

     (b)  The Company will issue to Executive options covering a total of 
400,000 shares pursuant to a Stock Option Agreement the terms of which shall 
be substantially as follows:

        (i)    150,000 shares with an exercise price that shall be equal to 
               the closing price of the Company's common stock on the Start 
               Date ("Start Price"), provided, however, that such options shall
               not vest until one (1) year from the Start Date; 

                                      9
<PAGE>
 
          (ii)  62,500 shares with an exercise price that shall be equal to the
                Start Price, but exercisable at any time during the term on and
                after the price of the Company's Common Stock has reached or
                exceeded the higher of $19.00 per share or a price which shall
                be equal to 125% of the Start Price;

         (iii)  62,500 shares at an exercise price that shall be the Start
                Price, but exercisable at any time during the term on and after
                the price of the Company's Common Stock has reached or exceeded
                the higher of $19.00 per share or a price which shall be equal
                to 150% of the Start Price; and

          (iv)  125,000 shares at an exercise price which will be the Start
                Price, but exercisable at any time during the term on and after
                the price of the Company's Common Stock has reached or exceeded
                the higher of $19.00 per share or a price which shall be equal
                to 200% of the Start Price.

     A portion of the options may be incentive stock options qualifying as 
such under the Internal Revenue Code. All options granted pursuant to this 
Section 7(b) shall be for ten (10) years and the Option Agreement shall 
provide for normal and usual anti-dilution protection. Furthermore, after the
execution of this Agreement the Chairman and the Executive shall explore the 
advisability of the Company adopting a Stock Appreciation Rights plan, the 
purpose of which shall be to provide Executive with compensation with which to
pay any tax incurred as a result of the lapsing of any restrictions on the 
restricted stock or the exercise of any of the options at an exercise price 
which is below the quoted market price of the Company's common stock on the 
date of exercise. Any such Stock Appreciation Rights Plans shall (i) only be
adopted if the Chairman and the Executive agree that such Plan is in the best 
interests of the Company, and (ii) if granted to Executive, shall be in 
substitution, and in lieu of an equal number of shares of restricted stock or 
stock options granted under Section 7 hereof and not in addition to any of 
such restricted shares or stock options. Any stock acquired pursuant to the 
exercise of the option shall have no other holding period under the option 
agreement, other than as required by law.

     (c)  Neither the issuance of the restricted stock nor the granting of the
options provided in this Section 7 shall preclude the issuance to the 
Executive of additional options or stock. The Company agrees that during the 
term of the Executive's employment, the Executive shall be entitled to 
additional stock options and/or restricted stock consistent with the 
Executive's position with the Company as determined in the discretion of the 
Chairman. At the discretion of the Company, and upon the recommendation of the
Chairman, the lapse of any restrictions or the vesting period of any 
restricted shares or options may be accelerated based upon Executive's 
performance.

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

     The Executive hereby represents and warrants to the Company that he is 
not bound by any Employment Agreement, restrictive covenant, confidentiality

hereunder or as the President and Chief Operating Officer of the Company. The 
Executive further represents, warrants and agrees that he will not use any 
trade secret, confidential or other proprietary information of any former

representatives.

  Co., Inc.

Dear Joe:

     Reference is made to the Employment Agreement dated April 4, 1983 (as 
amended August 16, 1985) between yourself and Goldenberg Plywood and Lumber 
Co., Inc. (the "Company").

     This letter shall constitute a memorandum of our understanding and 
agreement pursuant to which the term of the aforementioned Employment 
Agreement shall be extended for five (5) years until April 30, 1993 upon the 
same terms and conditions except that:

          1.  The initial fixed compensation referred to in Paragraph 4(a) of 
the Employment Agreement shall be $300,000 for the period commencing January 
1, 1988; and

          2.  You shall receive a bonus each year equal to ten (10%) percent 
of the Income before Working Capital Charges and Management Fee of the 
Company. In the event that Income before Working Capital charges and 
Management Fees is less than $3 Million in any one year, then you shall not be
entitled to receive any bonus for that year. The bonus payable for each year 
during the term of this Agreement shall be based on the Income before 
Management Fee for the calendar year ending December 31 next preceeding the 
commencement of the applicable Employment Year provided, however, that the 
initial bonus shall be payable during the Employment Year commencing January 
1, 1988 based upon the Income Before Management Fees of the Company for the 
year ended December 31, 1988 to be payable in two installments no later than 
September 1, 1988 and no later than March 31, 1989, respectively. Payments for
subsequent years shall be similarly made on September 1 and March 31 
thereafter. The payment to be made on or before September 1 shall be deemed to
be an estimated payment based upon the results of operations for the first six
months of the year. The second payment shall reflect the balance due based 
upon the results of operations for the entire year. In the event the estimated
payment made on or before September 1 exceeds the amount due based upon the 
results of operations for the full year, you will refund to us the 
overpayment.

          For purposes of this Agreement, Income before Management Fee shall 
mean the net operating profits of the Company computed after all charges 
including working capital charges payable to Ply-Gem (before provision for 
taxes based on income and before provision for management fees), as determined
on an accrual basis in accordance with generally accepted accounting 
principles consistent with the financial statements of the Company prepared 
for the year ended December 31, 1987 exclusive of (a) all gains and losses 
form the sale, exchange or other disposition of capital or fixed assets, (b) 
other profit and loss items which, for profit and loss statement purposes, are
treated as extraordinary income or expense items under generally accepted 
accounting principles, and (c) all expenses attributable to the purchase of 
the Company by Ply-Gem Industries, Inc. and amortization of goodwill and 
amortization of intangibles. Exhibit "A" attached hereto illustrated the 
computation of the Bonus.

        For the purposes of this Agreement Income before Working Capital 
charges and Management Fees shall mean the sum of Income before Management 
Fees plus Working Capital charges.

        3.  You may retire at any time subsequent to December 31, 1989 upon 
giving notice in the same fashion as is required pursuant to the terms of the 
Consulting Agreement between us dated September 18, 1987.

                                     -5-
<PAGE>
 
Company shall also refer to any subsidiary or affiliate of the Company 
including, but not limited to, Ply-Gem Industries, Inc.) to maintain as secret
and confidential all valuable and unique information heretofore or hereafter 
acquired, developed or used by the Company relating to the business, 
operations, employees and customers of the Company which gives the Company a 
competitive advantage in its industry (all such information is hereinafter 
referred to as "Confidential Information"). The Executive recognizes that the 
services to be performed by the Executive are special and unique, and that by 
reason of his duties, he will acquire Confidential Information. The Executive 
recognizes that all such Confidential Information is the property of the 
Company. In consideration of the Company's entering into this Agreement, the 
Executive agrees that:

             (i)  he shall never directly or indirectly, use, publish, 
         disseminate or otherwise disclose any Confidential Information 
         obtained during his employment by the Company without the prior 
         written consent of the Company's Board of Directors, acting 
         independently, it being understood that this subparagraph shall 
         survive the term of this Agreement; and

             (ii) during the term of his employment by the Company, he shall 

                                     -6-

<PAGE>
 
         exercise all due and diligent precautions to protect the integrity of
         the Company's customer lists, mailing lists and sources thereof,
         statistical data and compilations, agreements, contracts, manuals or
         other documents embodying any Confidential Information and, upon
         termination of his employment, he shall return all such documents
         (and copies thereof) in his possession or control.

The Executive agrees that the provisions of this paragraph (a) are reasonably 
necessary to protect the proprietary rights of the Company in the Confidential
Information and its trade secrets, goodwill and reputation.

         (b)(1)  During the Non-Competition Period (as hereinafter defined), 
the Executive shall not in any way, be engaged, directly or indirectly, 
anywhere in the United States (or for such lesser period of time or for such 
lesser geographical areas as may be determined by a court of law or equity to 
be a reasonable limitation on the competitive activities of the 
Executive) during such period as an employee, partner, officer, director, 
representative, consultant, agent or stockholder (other than as the holder of 
not more than five percent (5%) of the stock of a corporation the shares of 
which are publicly traded) of any corporation, partnership, proprietor--

                                     -7-
<PAGE>
 
ship or other form of business entity engaged in the business of distributing 
and fabricating plywood and board panels or other vinyl or board products for 
the construction or furniture industry or any other business of Company with 
respect to which Executive had supervisory authority at any time during the 
term of his employment with the Company anywhere in the continental United 
States. Without limiting the foregoing, during the Non-Competition Period the 
Executive shall not seek to persuade, directly or indirectly, any director, 
officer or employee of the Company to discontinue that individual's status or 
employment with the Company, nor to become employed in any activity similar to
or competitive with the activities of the Company, nor will he, directly or 
indirectly, hire or retain any such person, nor will he solicit or cause or 
authorize, directly or indirectly, to be solicited, for or on behalf of 
himself or any third party, from others who are customers of the Company, any
business which is competitive with the Company.

              (2)  For purposes of this Agreement, the Non-Competition Period 
shall mean the period ending on the date two years following the termination
of Executive's employment hereunder.

         (c)  The Executive acknowledges that any breach or threatened breach 
or alleged breach or alleged threatened breach by him of the provisions of 
this Section 7 can cause 

                                     -8-

<PAGE>
 
irreparable harm to the Company for which the Company would have no adequate 
remedy at law. In the event of a breach or threatened breach or an alleged 
breach or alleged threatened breach by the Executive of any of such 
provisions, the Company, in addition to any and all other rights and remedies 
it may have under this Agreement or otherwise, may immediately seek any 
judicial action that the Company may deem necessary including, without 
limitation, the obtaining of temporary and preliminary injunctive relief.

Mr. Herbert Dooskin
22 Cambridge Drive
North Caldwell, NJ  07006

Dear Mr. Dooskin:

     We have had discussions with you with respect to your employment as an 
executive of Ply-Gem Industries, Inc. (the "Company"). We have felt that it is
in each of our best interests for us to enter into an arrangement pursuant to 
which the Company shall have the benefit of your services for an extended 
period of time and you agree to commit yourself to the Company and to be 
obligated to serve as a principal executive officer of the Company during the 
foreseable future.

     This letter shall constitute the agreement between us with respect to 
your employment as a principal executive officer of the Company upon the 
following terms and conditions:

     1.  You have agreed to serve as a principal executive officer of the 
Company and we have agreed to employ you as such. This agreement shall 
commence on March 15, 1986 and, unless extended as set forth herein, shall 
terminate on March 31, 1988 (the "Employment Period"). As of April 1, 1987 and
on April 1 of each subsequent year thereafter, this agreement (and the 
Employment Period) shall be automatically extended for an additional year 
unless the Board of Directors of the Company shall decide

<PAGE>
 
otherwise and shall deliver to you written notice of their intent not to 
extend the contract as aforesaid beyond the then termination date. Such 
notice shall be delivered to you not later than the January 1 prior to the 
April 1 extension date. This agreement and the Employment Period shall be 
extended as aforesaid on the same terms and conditions as set forth herein 
including without limitation this extension provision. As illustration and as 
an example, unless notice of non-extension is delivered to you by the Board of
Directors prior to January 1, 1987, the agreement shall be extended until 
March 31, 1989. The Employment Period is therefore extended one additional 
year at that time. As of each subsequent April 1, the Employment Period shall 
be extended for an additional year unless notice is given to you as aforesaid 
prior to January 1 or the appropriate year.

        During the Employment Period you may be terminated only for cause, 
which is defined for the purpose of this agreement as a material breach of 
your obligations as an officer and an employee.

        You have further agreed that you will not voluntarily resign without 
as least three months advance written notice to us.

        2. During the Employment Period, you agree to serve as a principal 
executive officer of the Company and to perform such services consistent with 
such position as may be indicated from time to time by the Board of Directors.
By your designation as a principal executive officer it is understood that you
are to

                                     2.
<PAGE>
 
serve initially as Executive Vice President and as a Director of the Company. 
Subsequently you shall perform such other services and serve in such 
capacities as the Board of Directors shall from time to time indicate all as 
consistent with your position as a principal executive officer.

     You will not be required to relocate your residence or principal place of
employment outside of the New York Metropolitan Area without your written 
consent.

     3.  Anything in this agreement to the contrary notwithstanding, in the 
event of your physical or mental disability during the Employment Period under
such circumstances that you are unable to discharge your responsibilities in 
accordance with this agreement, or in the event of your death during the term 
of the Employment Period, you or your estate (as the case may be), shall 
continue to receive all payments of salary (in accordance with Paragraph 4 
hereof) and bonus (in accordance with Paragraph 5 hereof) for twelve months 
subsequent to the date of your disability or death, as the case may be. You 
have agreed to submit to such periodic physical examinations as we deem 
necessary and which are usual and customary for executives in positions such 
as yourself. You further agree to take such physical examinations as may be 
required in order for us to obtain life insurance on your life.

     4.  The salary to be paid to you during the Employment Period as 
foresaid shall be determined annually by the Board of Directors and shall be 
set and paid to you on a 

                                     3.

<PAGE>
 
calendar-year basis. Your salary shall be not less than $250,000 per annum 
which shall be payable in weekly installments. In addition, you shall receive 
all employee benefits and executive perquisites receivable by executive 
employees in capacities similar to yours. The company further agrees to waive 
any waiting period with respect to such benefits unless such waiver would 
constitute a violation of law or of an outstanding agreement to which the 
Company is a party.

     5.  The Board of Directors of the Company shall award to you an annual 
bonus reflective upon your performance and the performance of the Company for 
each year. For purposes of this paragraph the minimum bonus to be paid to you 
annually during the Employment Period shall be $50,000 per annum, which amount 
shall be due and payable to you irrespective of your performance or the 
performance of the Company. During December of each year commencing with 
December 1986, the Board of Directors shall determine whether the minimum 
bonus should be increased. The bonus shall be payable to you within thirty 
(30) days of each year end. (For example, the increase in the bonus, if any, 
to be determined in December 1986 shall be based upon performance during the 
year 1986 and the entire bonus shall be paid in January 1987). The bonus to be
payable to you shall be in the absolute discretion of the Board of Directors 
subject however to the minimum commitment set forth herein.

                                     4.
<PAGE>
 
     6.  During the Employment Period and for eighteen (18) months subsequent 
thereto, you have agreed that you will not in your individual capacity or as 
an officer or employee of any corporation involve yourself in business 
enterprises in competition with the Company or any of its subsidiaries as 
presently constituted. In recognition of the importance of the provisions of 
this paragraph to the Company, the Company shall have the right to immediate 
injunctive relief in the event of your violation of the provisions herein.

     7.  It is understood and agreed that your services during the Employment 
Period are to be deemed full-time employment and you shall devote such time as
is reasonably necessary in order to discharge your duties as aforesaid. You 
shall be entitled to reimbursement of all out-of-pocket expenses incurred by 
you in the course of the performance of your services at all times.

     8.  In consideration of your employment in accordance with this 
agreement, the Board of Directors has agreed to grant to you no later than May
1, 1986 a non-qualified stock option to purchase 75,000 shares of the 
Company's common stock. These options are to be exercisable for a period of 
ten (10) years and are to be substantially in the form of the stock option 
agreement attached hereto.

     9.  This agreement is binding upon and shall inure to our mutual benefit 
and to the benefit of our respective successors, heirs and assigns.

                                     5.

  additional year unless written notice is given to you as aforesaid prior to
  August 1 of the appropriate year."

        2.  The annual salary (as referred to and defined in Paragraph "5" of 
the Agreement) for the year commencing January 1, 1993 shall be $1,873,625. 
During all subsequent years (commencing January 1, 1994) your annual salary 
shall be $1,873,625, plus increases in accordance with the formula set forth 
in paragraph "5"of the Agreement.

        3. As further consideration of our mutual agreement to modify the
Agreement in the manner set forth herein, we have agreed to provide to you a
one-time loan in the principal amount of $3.5 million to be repaid by you in
ten periodic installments, any one of which together with the interest
thereon, or all of which, will be forgiven by Ply Gem in the event Ply Gem
meets certain profit milestones in the future. This loan shall be evidenced by
a promissory note and shall be repaid in ten equal annual installments
commencing April 30, 1994, together with interest at the rate of 7.30 % per
annum. Interest on the unpaid principal balance shall be paid annually
commencing April 30, 1994. The proceeds of the loan shall be used by you to
repay prior advances by the Company to you.

        Anything herein contained to the contrary notwithstanding, the Board 
of Directors of the Company may, by action prior to any principal payment 
date, forgive the payment of interest and the repayment of any principal 
payment. The determination of the Board of Directors of the Company with 
respect to such forgiveness shall be based upon such factors as the growth of 
the Company, increase in profitability and such other factors which may be 
determined from time to time by the Board of Directors.

        Notwithstanding the aforesaid, and payment of interest or principal 
due on April 30 of any year shall be forgiven if the net income of the Company
during the prior year shall have increased by at least 20% in excess of the 
net income of the Company during the next preceding year thereto. The 
repayment of the loan and all accrued interest thereon shall be forgiven prior 
to its maturity (i) upon your permanent disability, or (ii) upon an 
involuntary termination of your employment (except for "Cause") or upon a 
termination of employment initiated by

     Anything herein to the contrary notwithstanding, the provisions of the

Dear Mr. Silverman:

     Reference is made to the agreement between us dated February 19, 1991 
modifying and amending your employment agreement and in particular to the 
provisions of paragraph 2 thereof which provides for the amendment of 
paragraph 6 of the Agreement (as therein defined) in its entirety.

     Paragraph 6B refers to the forgiveness of the annual principal payments 
on the Promissory Note held by the Company. The Agreement did not reflect the 
intention of the Company to provide for forgiveness of interest on the same 
basis as the forgiveness of annual principal payments. 

     The Board of Directors at its meeting this date confirmed its 
understanding that both principal and interest payments were to be forgiven in
the manner set forth in Paragraph 6B of the Agreement with respect to the 
Promissory Note dated February 19, 1991 referred to above and to the 
Promissory Note dated September 15, 1991.

     We acknowledge receipt from you this date of amended Promissory Notes 
dated this date replacing the Promissory Note dated September 15, 1991 in the 
original principal amount of $1 million, now reduced to $900,000, and the 
Promissory Note dated February 19, 1991 in the original principal amount of 
$4.9 million, now reduced to $4,410,000.

     If this agreement constitutes an understanding of our agreement would you
please sign a copy and return it to us.

                                       Very truly yours,

Mr. Jeffrey S. silverman

Dear Mr. Silverman:

     Reference is made to your Employment Agreement dated July 17, 1986 and to 
certain subsequent modifications the last of which was dated June 2, 1990 (the
"Agreement"). In accordance with certain discussions that we have recently had
we have mutually deemed that it is in our respective best interests to modify 
in certain respects provisions of the Agreement in particular those set forth 
in paragraph 6 which relate to the payment of salary and bonus to you.

     We desire to modify the salary and bonus provisions of the Agreement on 
an ongoing basis to provide to you salary and bonus payments of a nature which
continue to provide significant performance incentives. In addition, in 
consideration of your agreement to modify the provisions for salary and bonus 
payments as presently set forth in the Agreement, we have agreed to provide to
you periodic incentive compensation payments. We have also agreed to provide 
to you a one time loan to be repaid in periodic installments any one of which 
or all of which will be forgiven by Ply Gem in the event that Ply Gem meets 
certain profit milestones in the future.

     1.  The provisions of Paragraph 5 of the Agreement shall be modified to 
provide that your annual salary for each year beginning in 1992 shall be not 
less than the salary in effect during the prior year of employment increased 
by the greater of:

     (i)  ten (10%) percent; or

Mr. Jeffery S. Silverman
Page 2                                          February 19, 1991

     (ii) the increase in the cost of living reflected by the Cost of Living 
Index of the Bureau of Labor Statistics for the New York, New Jersey 
Metropolitan region from January 1 of the preceding year to January 1 of the 
year during which the salary is to be effective.

     It is agreed that your salary in effect during 1991 shall be $1,248,746.

     2.  Paragraph 6 of the Agreement shall be amended in its entirety as 
follows:

     "6.  A.  The Company shall award to you an annual bonus reflective of the
  performance of the Company during each year. For purposes of this paragraph,
  the Base Bonus is deemed to be the average of the bonus paid to you in the
  years 1987, 1988 and 1989 ($365,000) which is the amount of the minimum
  bonus to be paid to you in 1991. On or prior to February 1 or each year
  commencing with February 1, 1992, the Board of Directors shall determine the
  bonus to be paid to you at that time which shall be based in part upon the
  Company's operating results from the prior year. The bonus payment to be
  awarded to you for each year commencing in 1992 shall be adjusted
  proportionately to reflect increases or decreases in net income of the
  Company for the prior year as compared with the next preceding year subject
  to a maximum payment (with respect to this formula) of $1 Million per year
  which maximum shall be increased by the greater of the increase in the cost
  of living during the prior year or 10%. As an example, assuming net income
  in 1991 and 1992 is $10 Million and $15 Million, respectively, and the bonus
  paid in 1992 was $365,000, then the bonus to be paid in 1993 will be
  $547,500 (a 50% increase measured by the 50% increase in net income). As
  long as the Company has net income, the bonus to be paid shall be at least
  equal to the Base Bonus. Notwithstanding the aforesaid, the bonus to be paid
  in 1992 shall reflect the percentage increase as compared with the Base
  Bonus subject to the maximum payment as above. In the event that the Board
  of Directors cannot determine with sufficient accuracy the bonus to be
  awarded to you in any year, then an estimate of such bonus shall be awarded
  to you to be adjusted as soon as is practicable and possible at such time as
  the results of operations for the year are available. The bonus as
  determined by the Company shall be the basis for the next subsequent year's

Jeffrey S. Silverman
Page 3                                                         February 19, 1991
 
  bonus computation. In the event the Company sustains a loss in any one year,
  then the basis shall be the Bonus received during the next preceding year in
  which the Company had a net income. No bonus shall be paid to you in the 
  event that the Company has a net loss. The bonus, as determined as aforesaid,
  shall be paid to you at such times as you may reasonably request. Notwith-
  standing the aforesaid, you may request and receive from time to time 
  advances of the anticipated bonus.

         "For purposes of clarification, the bonus awarded in accordance with 
  this Paragraph is awarded not only in recognition of increases in net income 
  but in recognition of the overall performance of the Company which, as an 
  example, may include the completion of acquisitions or additional financing,
  evaluation of future prospects of the Company and all other matters which 
  reflect on performance and prospects. The formula set forth above for 
  payment of the bonus is intended to reflect the Company's obligation for 
  payment of a minimum bonus to be paid and may be increased beyond the formula 
  at the sole discretion of the Board of Directors in recognition of factors 
  which the Board of Directors may deem important in awarding compensation to 
  you.

         "B.  The Company shall lend to you on this date $4.9 million, which 
  amount shall be evidenced by a promissory note and shall be repaid in ten 
  equal annual installments commencing April 30, 1992, together with interest 
  at the rate of (8.36%) per annum. Interest on the unpaid principal balance
  shall be paid annually commencing April 30, 1992. The proceeds of the loan
  shall be used by you to repay prior advances by the Company to you.

         "Anything herein contained to the contrary notwithstanding, the
  Board of Directors of the Company may, by action prior to any principal
  payment date, forgive the repayment of any principal payment. The 
  determination of the Board of Directors of the Company with respect to 
  forgiveness shall be based upon such factors as the growth of the Company,
  increase in profitability and such other factors which may be determined
  from time to time by the Board of Directors.

         "Notwithstanding the aforesaid, any payment due on April 30 of any 
  year shall be forgiven if the net income of the Company during the prior year 
  shall have increased by at least 20% in excess of the net income of the 
  Company during the next preceding year thereto. The loan shall be forgiven 
  prior to its maturity (i) upon your death or permanent disability, or (ii) 
  upon an involuntary termination of your employment (except for "Cause") or 
  upon a termination of employment initiated by you which occurs (a) with a 
  "Change in Employment Status" or (b) with "Good Reason" subsequent to a 
  "Change in Control Event" or "Potential Change in Control Event".

         "C.  The Company shall pay to you as incentive compensation $495,000 
  per annum on March 15 of each year commencing March 15, 1991 and continuing 
  until March 15, 2001. Commencing with the payment due on March 15, 2001. 
  Commencing with the payment due on March 15, 1992, these incentive 
  compensation payments are subject to (i) your continued employment (as an 
  employee or consultant) by the Company at such time as the payments are due to
  you except in the event of involuntary termination by the Company (except for 
  "Cause") or in the event of your resignation (a) as a result of a "Change in 
  Employment Status" or (b) for "Good Reason" subsequent to a "Change in Control
  Event" or "Potential Change in Control Event" and (ii) the Company having net 
  income in the year prior to payment of the deferred compensation payment at
  least equal to 75% of the net income of the Company for the year ended 
  December 31, 1990. In the event the earnings standard set forth above has 
  not been met, the deferred compensation payment can be made in any 
  subsequent year up to 2001 if the average earnings for all years from 1991
  through such subsequent year are at least 75% of the net income for the year
  ended December 31, 1990. In the event of your death or total disability, all
  of the then unpaid payments shall forthwith become due and payable to you or
  your estate, as the case may be.

         As used in this agreement, "Cause", "Change in Control Event", 
  "Potential Change in Control Event", "Change in Employment Status" and "Good
  Reason" shall have the definitions attached to this agreement."

         3.  Except as modified herein, the Agreement is hereby ratified and

Dear Mr. Silverman:

     Reference is made to your Employment Agreement dated July 17, 1986 (the 
"Agreement") and to certain subsequent modifications. In accordance with 
certain discussion that we have recently had, we have mutually deemed that it 
is in our respective best interests to modify in certain respects provisions 
of the Agreement with respect to death benefits and with respect to the
payment of life insurance proceeds.

     1.  For purposes of clarity, the following is a summary of the life 
insurance policies on your life, our respective interests therein and certain 
modifications with respect thereto:

         (a)  Paragraph 8(a) of the Agreement relates to a life insurance 
policy on your life (New England Mutual Life Insurance Company, Policy No. 
U111278, dated November 16, 1987). The Agreement provides that in the event of
your death during the Basic Employment Period or at such other specified 
times, $2.5 million of the amount received from the proceeds shall be payable 
as a death benefit to your estate or your designee. We have agreed to modify 
this provision to provide that from the date hereof, $2.5 million shall 
continue to be paid to your estate or designee as a death benefit and so much 
of the balance received from the proceeds of the policy as is necessary, even 
the remaining balance in its entirety, shall be applied to payment of advances
made to you then outstanding on the books of the Company. All other provisions
and conditions set forth in Paragraph 8(a) shall remain as heretofore.

                (b)  On October 16, 1987, we entered into an Agreement with 
respect to a Flexible Premium Advance Life Insurance Policy to be issued by 
New England Mutual Life Insurance Company in the principal amount of $5 
million (Policy No. 0111278). This Agreement relates to the payment of 
proceeds and the ownership of the policy benefits. The provisions of this 
Agreement shall remain in effect and shall not be modified at this time.

        2.  In order to provide an additional benefit to your estate in the 
event of your death, we have agreed that a new subparagraph (c) shall be added
to paragraph 8 of the Agreement as follows:

                "(c) In the event of your death during the Basic Employment 
  Agreement, the Consulting Period or during such period as you are mentally
  or physically disabled, and payments are being made to you in the manner set
  forth in Paragraph 3 above, the Company agrees that upon your death any
  amounts due to the Company from you as a result of advances or otherwise
  shall be forgiven and no requests for payments or demands thereof shall be
  made against the legal representatives of your estate."

        Except as modified herein the Agreement shall remain in full force and
effect.

                                       Very truly yours,

Dear Mr. Silverman:

     We have had discussions with you for a considerable period of time with 
respect to your employment as an executive of Ply-Gem Industries, Inc. (the 
"Company"). The Board of Directors of the Company are greatly appreciative of 
the results of operations during the past years which success has been in 
large part attributable to you.  We have acknowledged your leadership of the 
Company be electing you Chairman and constituting you Chief Executive Officer.
We are anxious that this very positive relationship shall continue. It is
apparent, therefore, that it is in our best interest for us to enter into a
formal arrangement with you pursuant to which the Company shall have the
benefit of your services for an extended period of time and you agree to
commit yourself to the Company and be obligated to serve as the Chief
Executive Officer of the Company during the foreseeable future.
<PAGE>
 
     This letter shall constitute the agreement between us with respect to 
your employment as the Chief Executive Officer of the Company upon the 
following terms and conditions:

     1.  You have agreed to serve as the Chief Executive Officer of the 
Company and we have agreed to employ you as such. This agreement shall be 
effective as of January 1, 1986 and shall terminate on December 31, 1990 (the 
"Basic Employment Period"). As of January 1, 1987 and on each subsequent year 
thereafter, this agreement shall be automatically extended for an additional 
year subsequent to its then expiration date unless the Board of Directors of 
the Company shall decide otherwise and shall deliver to you written notice of 
their intent not to extend the contract as aforesaid beyond the then 
termination date. Such notice shall be delivered to you not later than the 
August 1 prior to the January 1 extension date. This agreement shall be 
extended as aforesaid on the same terms and conditions as set forth herein 
including without limitation this renewal provision. As an illustration and as
an example, unless written notice is delivered to you by the Board of 
Directors on or prior to August 1, 1986, the agreement shall be extended until
December 31, 1991. The Basic Employment Period is therefore extended one 
additional year at that time. As of each subsequent January 1, the Basic 
Employment Period shall be extended for an additional year unless written 
notice is given to you as aforesaid prior to August 1 of the appropriate year.

                                     2.

<PAGE>
 
     2.  During the Basic Employment Period, you agree to serve as the Chief 
Executive Officer of the Company and to perform such services as may be 
indicated from time to time by the Board of Directors. The Board of Directors 
has elected you Chairman and has designated you Chief Executive Officer. In 
addition, you will continue to act as President. You shall also serve as a 
member of the Board of Directors without any additional compensation.

     Notwithstanding the aforesaid, however, in the event that the Board of 
Directors shall deem it advisable in their sole and unreviewable discretion at
any time not to continue to designate you as Chairman and Chief Executive 
Officer of the Company as aforesaid or in the event you shall not be elected 
to serve in that capacity or despite your election to such office you are not 
designated as sole Chief Executive Officer then at your sole and unreviewable 
option and discretion you shall then act in a consultative capacity for the 
Company for the balance of the Basic Employment Period (the "Consulting 
Term"). During such time as you shall act in such consultative capacity, you 
shall receive the salary, bonus, stock options, the right to severance pay and
insurance or death benefits, if any, and all other Company benefits that would
have been paid to you had you continued to serve as Chairman and Chief 
Executive Officer in the manner contemplated. As a consultant, you shall make 
recommendations to the Company when requested with respect to customer 
relations, marketing, new product development, corporate management, mergers, 
financing, acquisitions and long-term 

                                     3.

<PAGE>
 
planning. The payments to be made to you for your acting in a consultative 
capacity shall be made to you irrespective of whether or not the Company 
utilizes your services as a consultant.

     It is understood and agreed that services to be rendered by you during 
the Consulting Period are not to be deemed full-time employment and that, if 
requested, you shall be required to render consultation services on a 
reasonable basis at such times as shall be mutually determined and agreeable 
to you and the Company. You shall be entitled to reimbursement for all 
out-of-pocket expenses incurred by you in the course of rendering services to 
us in accordance with this agreement.

        In the event that during the Consulting Period you become 
incapacitated and, as a result, are unable to perform the consulting services 
required to be performed, nevertheless, you shall continue to be entitled to 
the compensation as provided for herein. We understand that during the 
Consulting Period you may be employed elsewhere on a full-time basis. The 
compensation to be paid to you during the Consulting Period shall not be 
decreased as a result of your full-time employment elsewhere.

        You have agreed that during the term of the Basic Employment Period 
you will not voluntarily resign without at least three months advance written 
notice to us.

        Any amounts to be paid to you in accordance with this agreement for 
salary, bonus or otherwise, shall be paid at your option in either cash or 
common stock of the Company. If you elect to receive common stock, then the 
shares to be received by

                                     4.
<PAGE>
 
you shall be valued based upon the closing price of the shares on the American
Stock Exchange (or such other exchange or market where the Company's shares 
are traded) on the day prior to the date payment is due and payable to you.

     3.  (a) Anything in this agreement to the contrary notwithstanding, in 
the event of your physical or mental disability during the Basic Employment 
Period or during the Consulting Period under such circumstances that you are 
unable to discharge your responsibilities in accordance with this agreement, 
or in the event of your death during the term of the Basic Employment Period 
or the Consulting Period, you or your estate (as the case may be) shall 
continue to receive all payments of salary (in accordance with Paragraph 5 
hereof) and bonus (in accordance with Paragraph 6 hereof) for the balance of 
the Basic Employment Period or Consulting Period as the case may be.

         (b)  In addition to and notwithstanding the foregoing, in the event 
of your physical or mental disability during the Basic Employment Period or 
during the Consulting Period, subsequent to the termination of payments to be 
made to you or your estate (in accordance with Paragraph 3(a) above), you are 
to receive during each year for the balance of such period of physical or 
mental disability, even to the extent of the balance of your life, an amount 
equal to fifty percent of the salary (in accordance with Paragraph 5 hereof) 
as in effect during the last year of the Basic Employment Period adjusted 
annually to reflect increases in the Cost of Living as measured by the 
Consumer Price

                                     5.
<PAGE>
 
Index published for the New York/New Jersey metropolitan area by the Bureau of
Labor Statistics. Notwithstanding the aforesaid, payments in accordance with 
this subparagraph subsequent to the Basic Employment Period or Consulting Term
shall not exceed $500,000 per annum. In addition, all medical insurance for 
yourself and your wife shall be kept in force. During the course of such 
payments, the Company agrees to continue to provide for you and your wife 
hospitalization, medical and major medical expense reimbursement insurance and
to pay all premiums with respect thereto.

     You have agreed to submit to such periodic physical examinations as we 
deem necessary and which are usual and customary for executives in positions 
such as yourself. You further agree to take such physical examinations as may 
be required in order for us to obtain, at our option, additional life 
insurance on your life.

     4.  We both recognize the importance of the maintenance of the Company's 
presence in New York City and for the Company's principal executive offices to
be located at such place.

     During the Basic Employment Period, the executive offices of the Company 
and your place of employment shall be maintained in New York, New York. In the
event that the Company shall determine that your place of employment shall be 
in a location other than New York, New York, then you shall have the right in 
your sole and unreviewable discretion to decline relocation to 

                                     6.

<PAGE>
 
such other site and to immediately assume the duties of consultant in the 
manner specified in Paragraph 2 above for the balance of the Basic Employment 
Period.

     5.  The salary to be paid to you for your services as the Chief Executive
Officer during the Basic Employment Period as well as amounts to be paid 
during the Consulting Period as aforesaid shall be set and paid to you on a 
calendar-year basis in installments not less frequently than weekly. The annual
salary in effect as of the date hereof is $429,000. Your salary for each
subsequent year beginning with 1987 shall be not less than the salary in effect
during the prior year of employment increased by the greater of:

         (i) ten (10%) percent; or

        (ii) the increase in the cost of living reflected by the Cost of 
  Living Index of the Bureau of Labor Statistics for the New York, New Jersey
  Metropolitan region from January 1, 1986 to January 1 of the year during
  which the salary is to be effective; or

       (iii) the salary in effect as of the preceding year increased by the 
  percentage increase (limited to 50%) in after-tax profits of the Company
  computed from the prior year. In the event the Company's after-tax profits
  shall be less than in the prior year ("Prior Year"), then in the subsequent
  year's computation for this purpose the percentage increase shall be
  measured by the increase in after-tax profits from the Prior Year (as
  defined). For example, if in 1987, 1988 and 1989 the after-tax profits were
  $3M, $2M and $5M, respectively, then for purposes of this paragraph the
  increase in after-tax profits for purposes of setting the 1990 salary shall
  be measured by the increase in after-tax profits in 1989 ($5M) as compared
  with 1987 ($3M) limited to a 50% increase .

                                     7.





<PAGE>
 
     As an illustration of the aforesaid, the Board of Directors shall set your
salary for the year 1987 as of January 1, 1987; the cost of living has 
increased by four (4%) percent during the period from January 1, 1986 through 
December 31, 1986; the Company has had an increase of fourteen (14%) percent in
its after-tax profits during 1986 as compared to 1985 then

     (a) salary in effect January 1, 1986 - 
     $429,000 per annum; and

     (b)(i) Salary in effect in 1986 increased by 
     10% - $471,900;

       (ii) 1986 salary increased by four (4%) percent (increase in the 
     cost of living from January 1, 1986 - December 31, 1986) - $446,660; 
     and

       (iii) salary in effect during 1986 increased by fourteen
     (14%) percent reflecting increase in net income after taxes - $489,560.

     The salary for 1987 shall be $489,560 reflecting the highest of the three
options set forth above.

     For purposes of this Paragraph and Paragraph 6 below, "net income after 
taxes of the Company" shall be determined by reference to the Company's audited
statements of income and expense prepared by the Company's independent auditors.

      6.  The Board of Directors of the Company shall award to you an annual 
bonus reflective upon the performance of the Company for each year. For 
purposes of this paragraph, the initial Base Bonus is deemed to be the bonus 
paid to you in 1985. During December of each year commencing with 1986, the 
Board of Directors shall determine the bonus to be paid to you based upon

                                     8.
<PAGE>
 
the performance of the Company during the past year (for example, the bonus to
be determined in 1986 shall be based upon the performance of the Company 
during the year 1986). The bonus payment to be awarded to you for each year 
commencing in 1986 shall be adjusted proportionately to reflect increases or 
decreases in net income after taxes of the Company for the current year as 
compared with the prior year. As an example assuming after-tax profits in 1987
and 1988 are $3M and $2M, respectively, and the 1987 bonus was $300,000, then 
the bonus to be paid in 1988 will be $200,000 (a 33-1/3% decrease measured by 
the 33-1/3% decrease in after-tax profits). In the event that the Board of 
Directors cannot determine with sufficient accuracy the bonus to be awarded to
you in any year then an estimate of such bonus shall be awarded to you to be 
adjusted as and after the commencement of the next year as soon as is 
practicable and possible at such time as the results of operations for the 
year are available. The Bonus as determined as aforesaid by the Board of 
Directors shall be the "Base Bonus" for the next subsequent year's bonus 
computation. In the event the Company sustains a loss in any one year, then 
the Base Bonus shall be the Bonus received during the next preceding year in 
which the Company had an after-tax profit. Notwithstanding the aforesaid, 
however, no bonus shall be paid to you in the event that the Company has a net
after tax loss. The bonus, as determined as aforesaid, shall be paid to you at
such times as you may reasonably request. Notwithstanding the aforesaid, you 
may request and receive from time to time advances of the anticipated bonus.

                                     9.
<PAGE>
 
     For purposes of clarification, the bonus awarded in accordance with this 
Paragraph is awarded not only in recognition of increases in net income after 
taxes but in recognition of the overall performance of the Company which, as 
an example, may include the completion of acquisitions or additional 
financing, evaluation of future prospects of the Company and all other matters
which reflect on performance and prospects. The formula set forth above for 
payment of the bonus is intended to reflect the Company's obligation for 
payment of a minimum bonus to be paid and may be increased at the sole 
discretion of the Board of Directors in recognition of factors which the Board
of Directors may deem important in awarding compensation to you.

     7.  The Company recognizes its obligation to continue its practice to 
grant to you each year options to purchase shares of Common Stock of the 
Company consistent with the grants of such options made to you heretofore. It 
is understood that a significant and important consideration in your entering 
into this agreement is your objective to increase your shareholdings in the 
Company. Therefore, the Company recognizes its obligation to grant to you 
options on an annual basis, at least in the amounts heretofore granted, and to
grant increases commensurate with and in proportion to increases in the 
profits of the Company.

     8.  (a) The Company has purchased a life insurance policy in the 
principal amount of $5 million on your life. In the event of your death during
the Basic Employment Period, the Consulting Term (as set forth in Paragraph 3)
or

                                     10.

<PAGE>
 
during such period as you are mentally or physically disabled and payments are
made to you in the manner set forth in Paragraph 3 above, the Company shall 
pay to your estate, or to your designee, $2.5 million of the amount received 
from the proceeds of the aforementioned policy as a death benefit. The Company
agrees to keep this policy, or a replacement satisfactory to you, in full 
force and effect during all of the periods specified above and to pay the 
premiums with respect thereto. The death benefit paid to your estate in 
accordance with this paragraph is in addition to all other payments (including
the payment of benefits) which the Company is obligated to make to you, your 
estate or to your family in accordance with this agreement.

         (b)  In the event of your death during the Basic Employment 
Agreement, the Consulting Period or during such period as you are mentally or 
physically disabled and payments are being made to you in the manner set forth
in Paragraph 3 above, the Company agrees to continue to provide your wife with 
hospitalization, medical and major medical expense reimbursement insurance 
during the balance of her life and to pay all premiums for insurance with 
respect thereto.

     9.  During the Basic Employment Period, the Consulting Term and for two 
(2) years subsequent thereto, you have agreed that you will not in your 
individual capacity or as an officer or employee of any corporation involve 
yourself in business enterprises in competition with the Company or any of its
subsidiaries as presently constituted. In recognition of the importance of the 
provisions of this paragraph to the Company,

                                     11.
<PAGE>
 
the Company shall have the right to immediate and injunctive relief in the 
event of your violation of the provisions herein. Notwithstanding the 
aforesaid, the provisions of this paragraph shall not be effective in the 
event of a change in control or the Company and your employment is terminated 
as a result thereof.

     For purposes of this paragraph, a change in control of the Company shall 
be deemed to have occurred in the manner more particularly defined, described 
and set forth (therein referred to as an "Event") in the resolutions of the 
Board of Directors of the Company at its meeting on August 7, 1985 relating to
severance pay for certain key executives.

     10.  It is understood and agreed that your services as Chief Executive 
Officer of the Company during the Basic Employment Period (except as may be 
provided in Paragraph 2 above) are to be deemed full-time employment and you 
shall devote such time as is reasonably necessary in order to discharge your 
duties as aforesaid. You shall be entitled to reimbursement of all 
out-of-pocket expenses incurred by you in the course of the performance of 
your services at all times during the term of your employment and subsequent 
thereto including without limitation the reimbursement to you of legal 
expenses which you may incur in enforcing the provisions of this agreement. You 
shall continue to receive all fringe benefits including but not limited to 
medical insurance in the nature of those then being paid to all employees of 
the Company.

         Executive shall return to the Company and its subsidiaries and 
         affiliates all such documents (and copies thereof) which are in the 
         possession or under the control of the Executive.

be a reasonable limitation on the competitive activities of the Executive) as 
an employee, partner, officer, director, representative, consultant, agent or 
stockholder of any corporation, partnership, proprietorship or other form of 
business entity (1) which is engaged in any business which is or was

are of a unique character which gives them a special value to the Company and 
its subsidiaries and affiliates. The Executive further acknowledges that any

                                STOCK OPTION

     OPTION AGREEMENT, made as of the     day of December, 1986, between 
Ply-Gem Industries, Inc., a New York corporation (hereinafter referred to as 
the "Company") and Ralph Delman, a Senior executive of a division or 
subsidiary of the Company (hereinafter referred to a "Delman").

     The Board of Directors of the Company has resolved that it is in the

     NOW, THEREFORE, in consideration of the mutual covenants hereinafter set 
forth and for other good and valuable consideration, the parties hereto have 
agreed and do hereby agree as follows:

     1.  GRANT OF OPTIONS.  The Company hereby grants to Delman the right and 
         ----------------
option (hereinafter referred to as the "Option") to purchase all or any part 
of an aggregate of 50,000 shares of the common stock, of the Company, 25 cents
par value (hereinafter referred to as "Common Stock"), on the terms and 
conditions hereinafter set forth in this option agreement, such number of 
shares of Common Stock being subject to adjustment as provided in paragraph 5 
hereof.
<PAGE>
 
     2.  PURCHASE PRICE.  The per share purchase price (hereinafter referred 
         ---------------
to as the "Option Price") of the shares of Common Stock covered by the Option 
shall be the lowest of (i) $10.75 per share, (ii) the closing price of a share
of common stock of the Company on the American Stock Exchange on December 9,
1986, or (iii) the closing price of a share of common stock of the Company on
the American Stock Exchange on the last business day preceding the date of
this Agreement.

     3.  DURATION OF OPTION.  The Option granted hereunder shall be for a 
         -------------------
period of ten (10) years form the date hereof. Subject to the provisions of 
this agreement, the Option may be exercised at any time or from time to time 
subsequent to two (2) years from the date hereof, as to any part of or all of 
the shares covered thereby.  The purchase price of the shares as to which the 
Option shall be exercised shall be paid in full in current funds at the time 
of exercise. The holder of the Option shall not have any rights of a 
stockholder with respect to the shares covered by the Option unless and until 
the certificate or certificates for such shares shall have been issued and 
delivered to him.

     Anything herein to the contrary notwithstanding, this Option shall be 
cancelled and be deemed null and void one (1) month subsequent to the 
termination of employment of Delman as a senior executive of a division or 
subsidiary of the Company unless such termination results from the physical or

                                     2.

<PAGE>
 
     4.  CONTINUATION AS EMPLOYEE.  Nothing in the Option granted hereunder or
         ------------------------
by reason of the granting of the Option shall confer upon Delman any right to 
be continued as a director, officer or employee of the Company or any 
subsidiary or division of the Company.

     5.  ADJUSTMENTS.  In the event of any change in the Common Stock of the 
         -----------
Company by reason of any merger, consolidation, recapitalization, 
reclassification, stock split-up, combination of shares or dividend payable in
Common Stock of the Company (in excess of five (5%) percent thereon), after the
date hereof, then appropriate adjustment shall be made in the number and kind 
of shares subject to the Option, and/or to the price of the Option, provided, 
however, that no fractional share shall be issued upon any such exercise, and 
the aggregate price paid shall be appropriately reduced on account of any 
fractional share not issued.  Any such adjustment made by the Board of 
Directors of the Company as provided in this paragraph 5 shall be conclusive.

     6.  EXERCISE OF OPTION.  Subject to the terms and conditions of this 
         ------------------
Option Agreement, the Option may be exercised by Delman, his heirs or assigns 
by delivery of written notice to the Company at its principle office which is 
now located at 919 Third Avenue, New York, New York. Such notice shall state
the election to exercise the Option and the number of shares in respect of
which it shall be exercised and shall be signed by the person or persons so
exercising the Option. Such notice shall be


                                     3. 

<PAGE>
 
accompanied by payment of the full purchase price of such shares in cash.
Payment of such purchase price shall be made by check payable to the Company.
The certificate or certificates for the shares as to which the Option shall
have been so exercised shall be registered in the name of the person or persons
so exercising the Option and shall be delivered, as provided above, to or
upon the written order of the person or persons exercising the Option within
(15) days (except as otherwise provided below in this paragraph 6) after the
due and proper exercise of this Option.

     It is expressly understood that it shall be a condition of the issuance
and delivery of the stock upon the due and proper exercise of the Option or 
any part thereof that prior to the delivery of the certificate or certificates
as to which the Option shall have been so exercised as aforesaid Delman (or
anyone acting under him or his heirs or assigns, as the case may be) shall
deliver to the Company a warranty and representation that it is the present
intention to acquire the shares being purchased for investment only and not for
distribution or resale and that an offer or sale by him of any such shares
will not be made or offered in violation of the provisions of the Securities
Act of 1933, as amended, or any rules and regulations thereunder. The time of
the delivery of such certificate or certificates of stock may be postponed by
the Company for such period as may be


                                     4.
<PAGE>
 
required by the Company to comply with any listing requirements of any 
national securities exchange or to comply with any applicable state or federal
law.

     The Company shall not be obligated to sell, issue or deliver any shares 
as to which the Option or any part thereof shall have been exercised as 
aforesaid unless the shares with respect to which the Option shall be 
exercised are at that time effectively registered or exempt from registration 
under the Securities Act of 1933, as amended.

     All shares that shall be purchased upon the exercise of the Option as 
provided herein shall be fully paid and non-assessable.

     Delman acknowledges that he is acquiring the options herein for investment
and not with a view towards distribution and that he will not sell, assign or 
transfer this option, or the shares acquired upon exercise thereof without an 
opinion of the counsel of the Company that the options or shares, as the case 
may be, are exempt from registration under the Securities Act of 1933 or if 
such shares or options are required to be registered, then such shares, 
assignment or sale shall not be effective prior to such registration.

     Anything herein to the contrary notwithstanding, this Option or the 
rights with respect thereto may not be transferred, assigned or collateralized
in any manner whatsoever it being the intent of the parties hereto that this 
Option is personal and may



                                     5.
<PAGE>
 
be exercised only by Delman, or in the event of his death, by the legal 
representatives of his estate not later than three (3) months from the date of
his death or two (2) months after the appointment of said legal 
representatives whichever date is later.

     Certificates for all Shares aquired upon the Sale shall be inscribed with
