                               PROSPECTUS SUMMARY

    THE FOLLOWING SUMMARY CONTAINS BASIC INFORMATION ABOUT THIS EXCHANGE OFFER.
IT LIKELY DOES NOT CONTAIN ALL THE INFORMATION THAT IS IMPORTANT TO YOU IN
MAKING A DECISION TO EXCHANGE THE OUTSTANDING NOTES. FOR A MORE COMPLETE
UNDERSTANDING OF THIS EXCHANGE OFFER, WE ENCOURAGE YOU TO READ THIS ENTIRE
DOCUMENT.

                               THE EXCHANGE OFFER

    On May 17, 1999, we completed a private offering of $175,000,000 aggregate
principal amount of our 10 1/2% senior subordinated notes due 2009, or the
outstanding notes. On the same day, we entered into a registration rights
agreement with the initial purchaser of the outstanding notes agreeing, among
other things, to deliver to you this prospectus and to use our best efforts to
complete this exchange offer within 210 days of the issuance of the outstanding
notes. You should read the discussion under the headings

"--Summary Description of the Exchange Notes" and "Description of the Exchange
Notes" for further information regarding the registered notes.

                                  THE COMPANY

    We are one of the largest manufacturers and distributors of residential
windows and doors in the United States based on 1998 pro forma net sales. We
offer a complete product line including aluminum, vinyl and wood windows and
doors to our customers, which include leading national homebuilders and home
center retailers. We have grown rapidly through a combination of internal growth
and complementary acquisitions. Our acquisitions of Heat, Inc. and Champagne
Industries, Inc. and their subsidiaries are a continuation of our strategy to
become the largest nationwide manufacturer and distributor of residential
windows and doors. The Heat acquisition strengthens our vinyl product offering,
enhances our nationwide presence and provides access to a proprietary
distribution network of 22 distribution centers. The Champagne acquisition
enhances our presence in the vinyl markets of Colorado, Kansas and Nebraska. Pro
forma for the transactions described in "Unaudited Pro Forma Consolidated
Financial Statements", we would have had net sales and adjusted EBITDA of $123.3
million and $10.3 million, respectively, for the three months ended March 31,
1999.

    We were founded in 1948 and we believe we are one of the two largest
manufacturers and distributors of residential non-wood windows and the third
largest manufacturer and distributor of residential doors in the United States
based on 1998 pro forma net sales. Our portfolio of products includes some of
the industry's most recognized brand names including ATRIUM-TM- and
WING-Registered Trademark-. Our full product line of aluminum, vinyl and wood
windows and doors enables us to differentiate ourselves from our competition,
leverage our multi-channel distribution system and be well positioned to benefit
from shifts in product preferences. Regional product preferences exist for
aluminum, vinyl and wood windows and doors, and a full product line is important
to serve our national customer base effectively. We pride ourselves on our
ability to provide to our nationwide customers the most suitable material based
on varying regional product preferences.

    We have 53 manufacturing facilities and distribution centers strategically
located in 24 states to service customers on a nationwide basis. We distribute
through multiple channels including direct distribution to large homebuilders
and independent contractors, one-step distribution through home centers and
lumberyards and two-step distribution to wholesalers and dealers who
subsequently resell to lumberyards, contractors and retailers. We believe that
our multi-channel distribution network allows us to reach the greatest number of
end customers and provide nationwide service to those customers.

COMPETITIVE STRENGTHS

    We believe that we have a competitive advantage in our markets due to our
following competitive strengths:

    - our leading market positions;

    - our strong brand name recognition;

    - our complete, high-quality product offering;

    - our multi-channel distribution network;

    - our established and diversified customer base; and

    - our low cost, vertically integrated manufacturing operations.

BUSINESS STRATEGY

    Our goal is to increase revenue growth and profitability and to strengthen
our leadership position in the residential window and door industry through the
following initiatives:

    - enhance our nationwide presence;

    - extend and cross-sell our product offerings;

    - capitalize on the ATRIUM brand name;

    - continue to pursue operational efficiencies; and

    - make selective strategic acquisitions.

                            THE ATRIUM TRANSACTIONS

    On May 17, 1999, we acquired Heat and its subsidiaries for approximately
$85.0 million, including $0.7 million of assumed indebtedness, and Champagne for
approximately $3.6 million, excluding $0.5 million to be paid upon the
achievement of certain operational targets. Additionally, a post closing
adjustment of $3.5 million was paid on May 17, 1999 related to working capital
delivered in excess of the target defined in the Heat stock purchase agreement.
On March 27, 1998 we purchased substantially all of the assets of Masterview
Window Company, LLC. On January 27, 1999, we purchased substantially all of the
assets of Delta Millwork, Inc. The Heat and Champagne acquisitions, the
transactions described in "--The 1998 Recapitalization," the Delta and
Masterview acquisitions, the offering of the outstanding notes, and the
application of the net proceeds from the offering of the outstanding notes are
referred to in this prospectus as the "Atrium transactions."

                           THE 1998 RECAPITALIZATION

    On October 2, 1998, GE Investment Private Placement Partners II, a Limited
Partnership, or GEIPPPII, which was formed by GE Investment Management
Incorporated, a wholly-owned subsidiary of General Electric Company, and
Ardshiel, Inc., a private equity firm, and certain of its affiliates, acquired
Atrium in a transaction valued at $225.0 million. In connection with the Atrium
acquisition, GEIPPPII and an affiliate of Ardshiel recapitalized Wing and Darby
and combined them with Atrium. As part of the recapitalization, GEIPPPII and
Ardshiel contributed to Atrium $50.0 million from the sale of common stock of
Atrium's ultimate parent and approximately $52.0 million in the implied value of
the Wing and Darby businesses. In addition, the proceeds from the issuance of
$45.0 million of discount debentures of Atrium Corporation to GEIPPPII and an
affiliate of Ardshiel were used to fund in part the acquisition of Atrium and
the repurchase of a portion of our existing senior subordinated notes. The
remaining sources of funds included a $205.0 million senior secured credit
facility consisting of a $30.0 million revolver, of

                                       2
<PAGE>
which $2.0 million was drawn at closing, a $75.0 million term loan B, and a
$100.0 million term loan C, of which approximately $29.1 million was repaid 36
days after closing. The revolving credit facility, term loan B and term loan C
mature in June 2004, June 2005 and June 2006, respectively. The transactions
described in this paragraph are referred to in this prospectus as the "1998
recapitalization."

                                EXPLANATORY NOTE

    The term "Wing" refers to Wing Industries, Inc. and its direct parent, Wing
Industries Holdings, Inc., as a combined entity and the term "Darby" refers to
R.G. Darby Company, Inc., R.G. Darby Company, Inc.-South, Total Trim, Inc.,
Total Trim, Inc.-South and their direct parent, Door Holdings, Inc., as a
combined entity, which entities were either contributed to Atrium and became our
subsidiaries in connection with the 1998 recapitalization or were formed
subsequent to the 1998 recapitalization.

                                    account pursuant to the exchange offer in exchange for
                                    outstanding notes that were acquired as a result of

                                    belief is incorrect and you transfer any exchange note
                                    issued to you in the exchange offer without delivering a
                                    prospectus meeting the requirements of the Securities
                                    Act or without an exemption from registration of your

CERTAIN U.S. FEDERAL INCOME TAX
  CONSEQUENCES....................  We believe with respect to the exchange of outstanding
                                    notes for exchange notes:

                                        - the exchange will not constitute a taxable
                                        exchange for U.S. federal income tax purposes;

                                        - you will not recognize gain or loss upon receipt
                                        of the exchange notes; and

                                        - you must include interest on the exchange notes in
                                        gross income to the same extent as the outstanding
                                          notes.

REGISTRATION RIGHTS AGREEMENT.....  You have the right to exchange the outstanding notes
                                    that you now hold for exchange notes with substantially
                                    identical terms. This exchange offer is intended to
                                    satisfy that right. If you do not tender your
                                    outstanding notes in the exchange offer, you will not
                                    have any further exchange or registration rights with
                                    respect to your outstanding notes. All untendered
                                    outstanding notes will continue to be subject to
                                    restrictions on transfer under the Securities Act.

EXCHANGE AGENT....................  State Street Bank and Trust Company is serving as our
                                    exchange agent in connection with the exchange offer.

                   SUMMARY DESCRIPTION OF THE EXCHANGE NOTES

    The form and terms of the exchange notes will be substantially the same as
the form and terms of the outstanding notes except that:

        (1) the exchange notes have been registered under the Securities Act and
    will not bear legends restricting the transfer of the exchange notes; and

        (2) the holders of the exchange notes, except for limited instances,
    will not be entitled to further registration rights under the registration
    rights agreement.

    The exchange notes will evidence the same debt as the outstanding notes and
will be entitled to the benefits of the indenture under which the outstanding
notes were issued.

                                    required to guarantee the outstanding notes on a senior
                                    subordinated basis.

                                    The guarantees will be unsecured senior subordinated
                                    obligations and will be subordinated to all existing and
                                    future senior indebtedness of the guarantors. The

                                    other existing and future senior subordinated
                                    indebtedness and will rank senior to all of the

                                    may redeem the exchange notes, in whole or in part, at

                                    of the principal amount thereof, plus accrued and unpaid

CERTAIN COVENANTS.................  The indenture governing the exchange notes will limit
                                    our ability and the ability of certain of our

                                        - in the case of certain of our subsidiaries,
                                        guarantee indebtedness, without guaranteeing the
                                          exchange notes,

                                        - engage in transactions with affiliates, and

                                    These covenants are subject to important exceptions and
                                    qualifications.

                 SUMMARY CONSOLIDATED HISTORICAL FINANCIAL DATA

    Prior to October 2, 1998, Atrium's consolidated historical financial
statements as filed with the Commission included its operations and the
operations of its subsidiaries. On October 2, 1998, pursuant to the 1998
recapitalization, the stock of Wing and Darby were contributed to Atrium.

    As Wing was determined to be the accounting acquiror in a "reverse
acquisition", the consolidated historical financial statements of Atrium, prior
to October 3, 1998, were replaced with the consolidated historical financial
statements of Wing. The summary consolidated historical income statement and
other data for 1998 include the operations of Wing from January 1 through
December 31 and the operations of Atrium and Darby from October 3 through
December 31. The summary consolidated historical income statement and other data
for the three months ended March 31, 1999 include the operations of Atrium, Wing
and Darby. The summary consolidated historical income statement data and other
data for the years ended December 31, 1994, 1995 and 1997, the three months
ended March 31, 1998 and the periods ended October 25, 1996 and December 31,
1996 only include the operations and accounts of Wing and its predecessor.

    Wing was acquired by its present controlling shareholders on October 25,
1996. The December 31, 1998 summary consolidated historical balance sheet data
includes the accounts of Atrium, Wing and Darby. The December 31, 1994, 1995,
1996 and 1997 and October 25, 1996 summary consolidated historical balance sheet
data only include the accounts of Wing and its predecessor. The references in
the "Summary Consolidated Historical Financial Data of Atrium (after the 1998
recapitalization)" to the periods ended December 31, 1996 and October 25, 1996,
refer to the periods October 26, 1996 through December 31, 1996 and January 1,
1996 through October 25, 1996, respectively.

    The summary consolidated historical financial data of Atrium (previous
registrant) are provided for information purposes only. These include the
summary consolidated historical income statement data and other data for the
years ended December 31, 1994, 1995, 1996 and 1997, the nine months ended
September 30, 1997 and the period from January 1, 1998 to October 2, 1998, and
the summary consolidated historical balance sheet data as of December 31, 1994,
1995, 1996 and 1997, September 30, 1997 and October 2, 1998.

            SUMMARY CONSOLIDATED HISTORICAL FINANCIAL DATA OF ATRIUM
                       (AFTER THE 1998 RECAPITALIZATION)

    The summary consolidated historical income statement and other data set
forth below for the year ended December 31, 1995, the periods ended October 25,
1996 and December 31, 1996 and the years ended December 31, 1997 and 1998, and
the summary consolidated historical balance sheet data at December 31, 1995,
1996, 1997 and 1998 and October 25, 1996 were derived from Atrium's (after the
1998 recapitalization) audited consolidated financial statements. The summary
consolidated historical financial data as of and for the year ended December 31,
1994 and the three months ended March 31, 1998 and 1999, were derived from
Atrium's (after the 1998 recapitalization) unaudited consolidated financial
statements, which in the opinion of management reflect all adjustments necessary
for a fair presentation of results for such periods. The summary consolidated
historical financial data should be read in conjunction with "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
the financial statements, related notes and other financial information included
elsewhere in this prospectus.

(1) EBITDA represents income before interest, income taxes, extraordinary
    charge, depreciation and amortization, special charges, stock option
    compensation expense and certain non-recurring expenses related to
    acquisitions. While we do not intend for EBITDA to represent cash flow from
    operations as defined by GAAP and we do not suggest that you consider it as
    an indicator of operating performance or an alternative to cash flow or
    operating income (as measured by GAAP) or as a measure of liquidity, we
    include it herein to provide additional information with respect to our
    ability to meet our future debt service, capital expenditures and working
    capital requirements. See "Management's Discussion and Analysis of Financial
    Condition and Results of Operations." We believe EBITDA provides investors
    and analysts in the building materials industry the necessary information to
    analyze and compare our historical results on a comparable basis with other
    companies on the basis of operating performance, leverage and liquidity.
    However, as EBITDA is not defined by GAAP, it may not be calculated on the
    same basis as other similarly titled measures of other companies within the
    building materials industry.

    The summary consolidated historical financial data set forth below as of and
for each of the four years in the four-year period ended December 31, 1997 and
as of and for the period from January 1, 1998 to October 2, 1998 were derived
from Atrium's (previous registrant) audited consolidated financial statements.
The summary consolidated historical financial data as of and for the period
ended September 30, 1997 were derived from Atrium's (previous registrant)
unaudited consolidated financial statements, which in the opinion of management
reflect all the adjustments necessary for fair presentation of results for such

            UNAUDITED SUMMARY PRO FORMA CONSOLIDATED FINANCIAL DATA

    We present below the unaudited summary pro forma consolidated financial data
for Atrium. The unaudited summary pro forma consolidated financial data are
derived from the audited and unaudited historical financial statements listed in
the Index to Financial Statements on page F-1 and certain unaudited historical
financial statements of other acquired businesses. The unaudited summary pro
forma consolidated income statement and other data for the year ended December
31, 1998 give effect to the Atrium transactions as if they had occurred on
January 1, 1998. The unaudited summary pro forma consolidated income statement
and other data for the three months ended March 31, 1999 gives effect to the
acquisitions of Delta, Heat and Champagne and the offering of the outstanding
notes and our use of the proceeds as if they occurred on January 1, 1999. The
unaudited pro forma consolidated balance sheet data gives effect to the Heat and
Champagne acquisitions and the offering of the outstanding notes and our use of
the proceeds as if they had occurred on March 31, 1999.

    The unaudited summary pro forma consolidated financial data is presented for
illustrative purposes only and is not necessarily indicative of the operating
results or financial position that would have occurred if the Atrium
transactions had been consummated on the dates indicated nor are they
necessarily indicative of the results that may be expected or achieved in the
future. See also "Risk Factors-- Substantial Leverage and Debt Service,"

<PAGE>
                                  RISK FACTORS

    AN INVESTMENT IN THE EXCHANGE NOTES INVOLVES A HIGH DEGREE OF RISK. YOU
SHOULD CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS AND OTHER INFORMATION IN
THIS PROSPECTUS BEFORE DECIDING TO INVEST IN THE EXCHANGE NOTES.

OUR SUBSTANTIAL LEVERAGE AND DEBT SERVICE COULD ADVERSELY AFFECT OUR FINANCIAL
HEALTH AND PREVENT US FROM FULFILLING OUR OBLIGATIONS UNDER THE EXCHANGE NOTES.

    We have a significant amount of debt. On a pro forma basis, after giving
effect to the Heat and Champagne acquisitions and the offering of the
outstanding notes and our use of the proceeds, at March 31, 1999, we would have
had approximately $308.7 million of consolidated debt outstanding, of which
approximately $136.3 million would have been senior indebtedness (exclusive of
unused commitments under our revolving credit facility), which includes
approximately $1.3 million of senior indebtedness of our subsidiaries (exclusive
of their guarantee of approximately $135.0 million of our senior indebtedness)
and our total consolidated debt, as a percentage of capitalization, would have
been approximately 74%.

    Our high level of indebtedness could have important consequences to you. For
example, it could:

    - limit our ability to obtain additional financing to fund our growth
      strategy, working capital, capital expenditures, debt service requirements
      or other purposes;

    - limit our ability to use operating cash flow in other areas of our
      business because we must dedicate a substantial portion of these funds to
      make principal payments and fund debt service requirements;

    - increase our vulnerability to interest fluctuations because, on a pro
      forma basis, after giving effect to the Heat and Champagne acquisitions
      and the offering of the outstanding notes and our use of the proceeds,
      approximately $71.5 million of our debt would have been at variable
      interest rates as of March 31, 1999;

    - limit our ability to compete with others who are not as highly leveraged
      as we are; and

    - limit our ability to react to changing market conditions, changes in our
      industry and economic downturns.

    Our ability to meet our debt service obligations and to satisfy our other
obligations will depend upon our future operating performance. If in the future
we cannot generate sufficient cash from operations to make scheduled payments on
the exchange notes or to meet our other obligations, we will need to refinance
our debt, obtain additional debt or equity financing or sell assets. To the
extent we need to sell significant assets to make scheduled payments on the
exchange notes or meet our other obligations, such sales would have a material
adverse effect on our business, operating results or financial condition.

OUR EXISTING DEBT AGREEMENTS IMPOSE SIGNIFICANT RESTRICTIONS ON US.

    The operating and financial restrictions and covenants in our existing debt
agreements, including the indenture governing the exchange notes and our credit
facility, and any future financing agreements may adversely affect our ability
to finance future operations or capital needs or to engage in other business
activities. A breach of any of these restrictions or covenants could cause a
default under our debt, including the exchange notes. Such a default may trigger
defaults under our other debt instruments that contain cross-acceleration or
cross-default provisions. A significant portion of our indebtedness then may
become immediately due and payable. We are not certain whether we would have, or
be able to obtain, sufficient funds to make these accelerated payments,
including payments on the exchange notes.

WE MAY NOT BE ABLE TO INTEGRATE SUCCESSFULLY THE HEAT AND CHAMPAGNE BUSINESSES
AND OTHER BUSINESSES THAT WE MAY ACQUIRE IN THE FUTURE.

    Our future performance will depend heavily on our ability to integrate the
Heat and Champagne businesses and other businesses that we may acquire in the
future. In order to integrate the newly acquired businesses into our business,
we must integrate manufacturing facilities, extend our financial and management
controls and operating, administrative and information systems in a timely
manner and on satisfactory terms and conditions. We cannot assure you that we
will be able to integrate the Heat and Champagne businesses or other businesses
that we may acquire in the future or that we will be able to realize projected
cost savings and synergies in connection with such acquisitions on the timetable
contemplated or at all.

    Furthermore, the costs of the acquisitions of Heat and Champagne and of
acquisitions of other businesses that we may consummate in the future could have
an adverse effect on short-term operating results. Such costs could include:

    - restructuring charges associated with the acquisitions; and

    - other expenses associated with a change of control, as well as
      non-recurring acquisition costs including accounting and legal fees,
      investment banking fees, recognition of transaction-related obligations
      and various other acquisition-related costs.

    The integration of the Heat and Champagne businesses or other newly acquired
companies may also lead to diversion of management attention from other ongoing
business concerns. In addition, we may need to recruit additional managers to
supplement the incumbent management of newly acquired companies but we may not
have the ability to recruit additional managers with the skills necessary to
enhance the management of the acquired companies.

THE EXCHANGE NOTES WILL BE SUBORDINATE TO ALL OF OUR EXISTING AND FUTURE SENIOR
INDEBTEDNESS AND THE GUARANTEES WILL BE SUBORDINATE TO ALL EXISTING AND FUTURE
SENIOR INDEBTEDNESS OF THE GUARANTORS.

    The exchange notes will be subordinate to all of our existing and future
senior indebtedness. The guarantees will be subordinate to all existing and
future senior indebtedness of the guarantors. On a pro forma basis, after giving
effect to the Heat and Champagne acquisitions and the offering of the
outstanding notes and our use of the proceeds, at March 31, 1999, we would have
had approximately $136.3 million of senior indebtedness outstanding, exclusive
of unused commitments under our revolving credit facility, and the guarantors
would have had approximately $1.3 million of senior indebtedness outstanding,
exclusive of their guarantee of approximately $135.0 million of our senior
indebtedness.

    In the event of our bankruptcy, liquidation or dissolution, our assets would
be available to pay obligations on the exchange notes only after all payments
had been made on our senior indebtedness. Similarly, in the event of bankruptcy,
liquidation or dissolution of any guarantor, its assets would be available to
pay obligations on the exchange notes only after all payments had been made on
its senior indebtedness. We cannot assure you that sufficient assets will remain
to make any payments on the exchange notes. In addition, certain events of
default under our and the guarantors' senior indebtedness would prohibit us and
the guarantors from making any payments on the exchange notes or the guarantees.

WE MAY BE UNABLE TO PASS ON TO CUSTOMERS FLUCTUATIONS IN RAW MATERIAL COSTS AND
SUPPLY, AND INTERRUPTIONS OF OPERATIONS AT ANY OF OUR MANUFACTURING FACILITIES
OR SUPPLIERS' DELAYS MAY ADVERSELY AFFECT OUR BUSINESS.

    We purchase aluminum, vinyl, wood, glass and other raw materials from
various suppliers. While all of these materials are available from numerous
independent suppliers, commodity raw materials are subject to fluctuations in
price. We cannot assure you that severe shortages of such materials will not
occur in the future, which could increase the cost of, or delay the shipment of,
our products and have a material adverse effect on our operating results. In
addition, we may be unable to pass on to customers gradual increases in

                                       16
<PAGE>
raw material prices. Moreover, sharp increases in raw material prices are more
difficult to pass through to the customer in a short period of time and may
negatively impact our short-term financial performance.

    In addition, loss of or interruptions of operations at any of our
manufacturing facilities or suppliers experiencing delays or generating higher
costs could have an adverse effect on our business, operating results or
financial condition.

WE OPERATE IN A VERY COMPETITIVE BUSINESS ENVIRONMENT.

    We compete with other national and regional manufacturers in our markets,
including Reliant Building Products, Inc., Nortek Inc., Andersen Corporation,
American Architectual Products Company and Pella Corporation in the window
market, and Premdor, Inc. and Jeld-Wen in the door market. Certain of our
principal competitors may be less highly-leveraged than we are and have greater
financial resources than we do. Accordingly, such competitors may be better able
to withstand changes in conditions within the industries in which we operate and
may have significantly greater operating and financial flexibility than we do.

    As a result of the competitive environment in the markets in which we
operate, we face and will continue to face pressure on sales prices of our
products from competitors, as well as from large customers. As a result of such
pricing pressures, we may in the future experience reductions in the profit
margins on sales, or may be unable to pass future raw material price or labor
cost increases on to our customers which would also reduce profit margins. We
cannot assure you that we will not encounter increased competition in the future
which could have a material adverse effect on our business, operating results or
financial condition.

WE HAVE BEEN, AND MAY IN THE FUTURE BE, SUBJECT TO CLAIMS AND LIABILITIES UNDER
ENVIRONMENTAL, HEALTH AND SAFETY LAWS AND REGULATIONS.

    Our past and present operations and assets are subject to extensive federal,
state, local and foreign environmental laws and regulations pertaining to the
discharge of materials into the environment, the handling and disposal of
wastes, including solid and hazardous wastes, or otherwise relating to health,
safety and protection of the environment. We do not expect to make any
expenditures with respect to ongoing compliance with or remediation under these
environmental laws and regulations that would have a material adverse effect on
our business, operating results or financial condition. However, the applicable
requirements under the law may change at any time.

    The nature of our past and present operations and assets expose us to the
risk of claims under these environmental, health and safety laws and
regulations. We cannot assure you that material costs or liabilities will not be
incurred in connection with such claims. We have been subject to such claims in
the course of our operations, and have made expenditures to address these known
conditions in a manner consistent with applicable laws and regulations. Based on
our experience to date, we do not believe that these existing claims will have
any further material adverse effect on our business, operating results or
financial condition. We cannot assure you, however, that the discovery of
presently unknown environmental conditions, changes in environmental, health,
and safety laws and regulations or other unanticipated events will not give rise
to claims that may involve material expenditures or liabilities.

    Prior to 1993 we received correspondence in which we were named as
potentially responsible parties at two Superfund sites, pursuant to the
Comprehensive Environmental Response, Compensation and Liability Act of 1980, as
amended or comparable state statutes. In one instance, we have entered into a
settlement and in the other instance, the group of potentially responsible
parties has negotiated a proposed remediation plan which has been approved by
the relevant state agency and is being reviewed by the United States
Environmental Protection Agency. Based on the actions taken to date and our
current insurance coverage, we believe that any liability associated with the
Superfund sites does not currently have and will not have a material adverse
effect on our business, operating results or financial condition.

                                       17
<PAGE>
However, because the Comprehensive Environmental Response, Compensation and
Liability Act provides for strict, and sometimes joint and several liability, we
cannot assure you that the liabilities in question will not result in material
expenditures in the future.

TRENDS IN THE HOUSING SECTOR AND IN GENERAL ECONOMIC CONDITIONS DIRECTLY IMPACT
OUR FINANCIAL PERFORMANCE.

    Demand in the window and door manufacturing and distribution industry is
influenced by new home construction activity. For the year ended December 31,
1998, we estimate that approximately 42% of our pro forma net sales were related
to new home construction. Trends in the housing sector directly impact our
financial performance. Accordingly, the strength of the U.S. economy, the age of
existing home stock, job growth, interest rates, consumer confidence and the
availability of consumer credit, as well as demographic factors such as the
migration into the United States and migration of the population within the
United States have a direct impact on our business. Cyclical declines in new
housing starts may have a material adverse effect on our business, operating
results or financial condition.

OUR BUSINESS WOULD BE SERIOUSLY IMPAIRED IF WE LOST OUR CURRENT RELATIONSHIP
WITH THE HOME DEPOT.

    We have a significant relationship with The Home Depot, one of the largest
home center retailers. The Home Depot accounted for approximately 23% of our pro
forma net sales for the year ended December 31, 1998. Our operating and
financial performance is currently dependent, in part, upon our relationship
with this customer. We cannot assure you that we will be able to maintain such
relationship consistent with historic levels or at all.

OUR BUSINESS IS SUBJECT TO SEASONALITY.

    Markets for our building-related products are seasonal. Historically, our
window business has experienced increased sales in the second and third quarters
of the year due to increased construction during those periods. Because interior
construction and repair increase during the winter months, the first and fourth
quarters of the year have historically been peak seasons for our door products,
particularly our interior doors. We cannot assure you that these seasonal trends
will not have a material adverse effect on our business, operating results or
financial condition.

THE LOSS OF CERTAIN KEY OFFICERS OR EMPLOYEES OR INABILITY TO FIND A CHIEF
EXECUTIVE OFFICER COULD ADVERSELY EFFECT US.

    The success of our business is materially dependent upon the continued
services of certain of our key officers and employees. The loss of such key
personnel could have a material adverse effect on our business, operating
results or financial condition. While we have non-competition agreements with
certain key officers and employees, we cannot assure you that a court will find
such agreements enforceable under applicable state law.

    In addition, we are currently engaged in a search for a chief executive
officer. We cannot assure you that we will find a suitable candidate in the near
future or that such candidate will be able to manage our business effectively,
but we believe that our current management structure is sufficient to operate
our business.

OUR BUSINESS MAY BE ADVERSELY AFFECTED BY POTENTIAL LABOR DISPUTES.

    Approximately 36% of our hourly employees are covered by three-year
collective bargaining agreements which expire in 2001. We cannot assure you that
we will not experience work stoppages or slowdowns in the future. In addition,
we cannot assure you that our non-union facilities will not become subject to
labor union organizing efforts or that labor costs will not materially increase.

                                       18
<PAGE>
WE MAY NOT BE ABLE TO PROTECT OUR PROPRIETARY RIGHTS OR REGISTER OUR SIGNIFICANT
MARKS.

    We rely on a combination of patent, copyright and trademark laws, trade
secrets, confidentiality and non-disclosure agreements and other contractual
provisions to protect our proprietary rights, measures that provide only limited
protection. We cannot assure you that our means of protecting our proprietary
rights will be adequate or that competitors will not independently develop
similar technologies.

    We have applied to register certain of our trademarks. We cannot assure you
that we will obtain registrations of principal marks in key markets. Failure to
obtain registrations could compromise our ability to protect our trademarks and
brands and could increase the risk of challenge from third parties to our use of
our trademarks and brands. Our failure to enforce and protect our intellectual
property rights or obtain from third parties the right to use necessary
intellectual property could have a material adverse effect on our business,
operating results or financial condition.

THE YEAR 2000 PROBLEM WILL REQUIRE SIGNIFICANT EXPENDITURES AND COULD DISRUPT
OUR OPERATIONS, IMPACTING OUR REVENUES.

    We are assessing the impact of the Year 2000 problem and have or intend to
modify portions of our hardware and software so that our computer systems will
function properly with respect to dates in the Year 2000 and thereafter. Much of
our assessment efforts have involved and depends on inquiries with our major
suppliers and customers as to their Year 2000 compliance. Substantially all of
our major suppliers and customers have indicated that their Year 2000 testing
and remediation programs are complete or will be complete by the end of the
third quarter of 1999. We have not, however, tested or independently verified
the Year 2000 compliance of our major suppliers and customers.

    We face certain risks related to the Year 2000 problem including potential
disruptions in our operations due to Year 2000 problems with our systems,
potential disruptions in material supply due to Year 2000 problems with our
suppliers' systems and potential loss of sales or delayed cash collections in
the event of Year 2000 problems with our customers' systems. Although we have
not formalized a contingency plan to address the problems associated with these
risks, there are several factors that we believe may mitigate potential Year
2000 problems. Because our business has only recently been computerized, we
believe we can run our business without significant interruptions using manual
labor and "paper" systems in the event of a Year 2000 problem with our systems.
In addition, because we source our materials from several suppliers, we believe
we have decreased the likelihood that a Year 2000 disruption at one of our
suppliers will materially interrupt our material supply. Although we believe
these factors mitigate our Year 2000 risks, we cannot assure you that problems
arising from these risks will not have a material adverse effect on our
business, operating results or financial condition.

    Although we believe that the Year 2000 problem will not pose significant
operational problems for us, we cannot assure you that our computer systems or
the computer systems of companies we acquire or the computer systems of other
companies with whom we conduct business will be Year 2000 compliant prior to
December 31, 1999. Furthermore, we cannot assure you that the inability of any
such systems to process accurately Year 2000 data will not have a material
adverse effect on our business, operating results or financial condition.

WE MAY NOT HAVE SUFFICIENT FUNDS TO FINANCE THE CHANGE OF CONTROL OFFER REQUIRED
BY THE INDENTURE OR OTHER AMOUNTS PAYABLE UPON A CHANGE OF CONTROL.

    Upon the occurrence of a change of control, we will be required to offer to
purchase all of the outstanding exchange notes. Furthermore, a change of control
will result in an event of default under our credit facility, permitting the
lenders to accelerate all unpaid amounts, in which case such indebtedness would
be required to be repaid in full before repurchase of the exchange notes. We
cannot assure you we will have funds available to pay the accelerated amounts
and to repurchase the exchange notes.

                                       19
<PAGE>
    In addition, a change of control under our indenture will also constitute a
change of control for purposes of the indenture governing the discount
debentures issued by our parent, Atrium Corporation. In such case, Atrium
Corporation will be required to repurchase the discount debentures.

GEIPPPII AND ARDSHIEL, OUR CONTROLLING STOCKHOLDERS, HAVE A SIGNIFICANT
INFLUENCE OVER OUR MANAGEMENT AND POLICIES AND THEIR INTERESTS MAY DIFFER FROM
THE INTERESTS OF HOLDERS OF THE EXCHANGE NOTES.

    GEIPPPII and Ardshiel own approximately 97% of the outstanding shares of
common stock of our ultimate parent, D and W Holdings, Inc. As a result of this
ownership and the provisions of the stockholders agreement executed by the
stockholders of D and W Holdings, GEIPPPII and Ardshiel are able to direct the
election of 8 of the 9 members of the Board of Directors of D and W Holdings and
therefore direct our management and policies. The interests of GEIPPPII and
Ardshiel may differ from the interests of holders of the exchange notes. The
stockholders agreement also provides that we cannot take certain actions without
obtaining the prior written consent of GEIPPPII and that D and W Holdings will
cause us to make dividend payments to make interest and principal payments on,
or to repurchase, redeem or repay, the discount debentures.

AN ACTIVE TRADING PUBLIC MARKET MAY NOT DEVELOP FOR THE EXCHANGE NOTES CAUSING
DIFFICULTIES FOR YOU IF YOU TRY TO RESELL THE EXCHANGE NOTES.

    There is no established trading market for the exchange notes or the
outstanding notes. Although the initial purchaser of the outstanding notes has
informed us that it intends to make a market in the outstanding notes and the
exchange notes, it has no obligation to do so and may discontinue making a
market at any time without notice. Furthermore, we do not intend to apply for
listing of the exchange notes on any securities exchange or for quotation
through the National Association of Securities Dealers Automated Quotation
System.

    The liquidity of and trading market for the exchange notes depends upon the
number of holders of the exchange notes, our performance, the market for similar
securities, the interest of securities dealers in making a market in the
exchange notes, and other factors. As a result, we cannot assure you as to the
development of a liquid trading market for the exchange notes.

UNDER CERTAIN CIRCUMSTANCES, A COURT COULD SUBORDINATE OR AVOID ANY OF THE
GUARANTEES.

    Although laws differ among various jurisdictions, in general, under federal
bankruptcy laws and comparable provisions of state fraudulent conveyance laws,
under certain circumstances a court could subordinate or avoid any of the
guarantees.

    If a court avoided a guarantee as a result of fraudulent conveyance, or held
it unenforceable for any other reason, holders of the exchange notes would cease
to have a claim against the relevant guarantor and would be solely creditors of
Atrium and the other guarantors.

    We believe that the guarantees are being incurred for proper purposes and in
good faith. This belief is based on our analysis of internal cash flow
projections and estimated values of assets and liabilities of the guarantors at
the time of this offering. We cannot assure you, however, that a court passing
on these issues would make the same determination.

                           FORWARD-LOOKING STATEMENTS

    This prospectus includes forward-looking statements. We have based these
forward-looking statements on our current expectations and projections about
future events. We caution prospective investors that forward-looking statements
are not guarantees of future performance. These forward-looking statements are
subject to risks, uncertainties, and assumptions about us, including, among
other things:

    - our anticipated growth strategies;

    - our ability to integrate acquired businesses, including, but not limited
      to, Heat and Champagne;

    - our intention to introduce new products;

    - anticipated trends in our businesses and the economy, including trends in
      the markets for windows and doors, the availability of consumer credit,
      interest rates, employment, levels of consumer confidence, consumer
      preferences, new housing starts, raw material costs and pricing pressures;

    - our future capital expenditures; and

    - our ability to continue to control costs and maintain quality.

    Many of these factors are beyond our control, and our actual results could
differ materially from those discussed in these statements. In light of these
risks, uncertainties and assumptions, you should not place undue reliance on
these forward-looking statements. We undertake no obligation to update or revise
any forward-looking statements or the reasons why actual results may differ,
whether as a result of new information, future events or otherwise.

                                USE OF PROCEEDS

    This exchange offer is intended to satisfy certain of our obligations under
the registration rights agreement entered in connection with the offering of the
outstanding notes. We will not receive any cash proceeds from the exchange
offer. In consideration for issuing the exchange notes, we will receive
outstanding notes in like principal amount. We will cancel all outstanding notes
surrendered in exchange for the exchange notes. Accordingly, issuance of the
exchange notes will not result in any change in our indebtedness.

    In addition to financing the acquisitions of Heat and Champagne, we used the
$172.4 million of proceeds from the offering of the outstanding notes to:

    - repay certain of our borrowings under our credit facility, including
      accrued interest through date of repayment,

    - retire our remaining existing senior subordinated notes including accrued
      interest through the date of repayment and repurchase premium,

    - fund a distribution to Atrium Corporation to repurchase a portion of the
      discount debentures, including accreted discount through the date of
      repurchase, held by GEIPPPII and an affiliate of Ardshiel, and

    - pay transaction fees and expenses.

                               THE EXCHANGE OFFER

    The following discussion summarizes the material terms of the exchange
offer, including those set forth in the letter of transmittal distributed with
this prospectus. This summary is qualified, in its entirety by reference to the
full text of the documents underlying the exchange offer, including the
indenture and the registration rights agreement governing the exchange notes,
which are exhibits to the exchange offer registration statement of which this
prospectus is a part.

GENERAL

    In connection with the sale of the outstanding notes to the initial
purchaser, we entered into a registration rights agreement, dated May 17, 1999,
with Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated as
initial purchaser.

    The registration rights agreement requires among other things that we:

    - file with the Commission within 60 days after the original issue date of
      the outstanding notes a registration statement under the Securities Act in
      connection with the issue of the exchange notes;

    - use our best efforts to cause the registration statement relating to such
      registered exchange offer to become effective under the Securities Act
      within 180 days after the original issue date of the outstanding notes;

    - use our best efforts to have the registration statement relating to the
      exchange offer to remain effective until the closing of the exchange
      offer;

    - use our best efforts to commence the exchange offer and cause such
      exchange offer to be consummated within 210 days after the original issue
      date of the outstanding notes; and

    - upon the effectiveness of the exchange offer registration statement,
      commence the exchange offer and keep the exchange offer open for not less
      than 20 business days, or longer if required by applicable law.

    If we consummate this exchange offer within the required time periods, we
will satisfy certain of our obligations under the registration rights agreement.
This prospectus, together with the letter of transmittal, is being sent to all
beneficial holders of the outstanding notes known to us.

    In addition, we agreed, under the registration rights agreement, to file a
shelf registration statement pursuant to Rule 415 under the Securities Act, if:

    - applicable law or the Commission's policy do not permit us to effect the
      exchange offer;

    - for any other reason the exchange offer is not consummated within 210 days
      after the original issuance date of the outstanding notes;

    - any holder of outstanding notes notifies us within 20 business days after
      the commencement of the exchange offer that (1) due to a change in
      applicable law or the Commission's policy it is not entitled to
      participate in the exchange offer or it may not resell the exchange notes
      without delivering a prospectus and the appropriate prospectus is not
      available or (2) is a broker-dealer and owns outstanding notes acquired
      directly from us or one of our affiliates; or

    - the holders of a majority of outstanding notes may not resell the exchange
      notes without restriction under the Securities Act and under applicable
      blue sky or state securities law.

    We have agreed to use our best efforts to cause such shelf registration
statement to become effective under the Securities Act as soon as practicable
but in no event later than 60 days after the filing of the shelf registration
statement. In addition, we agreed to use our best efforts to keep such shelf
registration

                                       22
<PAGE>
statement continually effective, supplemented and amended for a period of at
least two years following the effective date of the shelf registration
statement, or such shorter period as will terminate when all outstanding notes
covered by such shelf registration statement have been sold.

    Except as we have described, this prospectus may not be used for any offer
to resell, resale or other transfer of exchange notes.

    Except as described above, after consummation of the exchange offer, holders
of outstanding notes will have no registration or exchange rights under the
registration rights agreement.

REGISTRATION DEFAULTS; LIQUIDATED DAMAGES

    If either of the following registration defaults occur, we have agreed to
pay liquidated damages to each affected holder of outstanding notes:

    - the registration statement related to the exchange offer or shelf
      registration statement is not timely filed or declared effective or ceases
      to be effective or fails to be usable for its intended purpose without
      being succeeded immediately by an additional registration statement
      covering all outstanding notes that is filed and is declared effective, or

    - if the exchange offer has not been consummated on or prior to the 210th
      day after the original issuance date of the outstanding notes.

    Liquidated damages will accrue and become payable on the outstanding notes
as follows:

    - with respect to the first 90-day period while a registration default is
      continuing immediately following the occurrence of such registration
      default, in an amount equal to 0.25% per annum of the principal amount of
      the outstanding notes; and

    - the amount of liquidated damages will increase by an additional 0.25% per
      annum of the principal amount of the outstanding notes for each subsequent
      90-day period while a registration default is continuing until all
      registration defaults have been cured, up to an aggregate maximum amount
      of 1.00% per annum of the principal amount of the outstanding notes.

    Liquidated damages shall be computed based on the actual number of days
elapsed during which any such registration default exists. Following the cure of
a registration default, the accrual of liquidated damages with respect to such
registration default will cease.

EXPIRATION DATE; EXTENSIONS; AMENDMENTS

    The expiration date shall mean 5:00 p.m., New York City time, on September
14, 1999, unless we, in our sole discretion, extend the exchange offer, in which
case the expiration date will be the latest date and time to which the exchange
offer is extended.

    To extend the exchange offer, we will notify the exchange agent of any
extension by oral or written notice, followed by a public announcement thereof
no later than 9:00 a.m., New York City time, on the next business day after the
previously scheduled expiration date. In no event will the expiration date be
extended to a date more than 30 days after effectiveness of the registration
statement.

    We reserve the right, in our reasonable judgment:

        (1) to delay accepting any outstanding notes, to extend the exchange
    offer or to terminate the exchange offer if any of the conditions described
    below have not been satisfied, by giving oral or written notice of such
    delay, extension or termination to the exchange agent, or

        (2) to amend the terms of the exchange offer in any manner.

                                       23
<PAGE>
Any such delay in acceptance, extension, termination or amendment will be
followed as promptly as practicable by a public announcement.

TERMS OF THE EXCHANGE OFFER

    Upon the terms and subject to the conditions set forth in this prospectus
and in the letter of transmittal, we will accept any and all outstanding notes
validly tendered and not withdrawn prior to 5:00 p.m., New York City time on the
expiration date. We will issue $1,000 principal amount of exchange notes in
exchange for each $1,000 principal amount of outstanding notes accepted in the
exchange offer. Holders of the outstanding notes may tender some or all of their
outstanding notes pursuant to the exchange offer.

    The exchange notes will evidence the same debt as the outstanding notes and
will be entitled to the benefits of the indenture. The form and terms of the
exchange notes are substantially the same as the form and terms of the
outstanding notes, except that:

    - the exchange notes have been registered under the Securities Act and thus
      will not bear legends restricting their transfer; and

    - holders of the exchange notes generally will not be entitled to certain
      rights under the registration rights agreement or liquidated damages,
      which rights generally will terminate after consummation of the exchange
      offer.

    Holders of outstanding notes do not have any appraisal or dissenters' rights
under the Delaware General Corporation Law or the indenture in connection with
the exchange offer. We intend to conduct the exchange offer in accordance with
the applicable requirements of the Securities Exchange Act, as amended and the
rules and regulations of the Commission thereunder, including Rule 14e-1.

    We shall be deemed to have accepted validly tendered outstanding notes when,
as and if we have given oral or written notice thereof to the exchange agent.
The exchange agent will act as agent for the tendering holders pursuant to the
exchange agent agreement for the purpose of receiving the exchange notes from
us.

    If any tendered outstanding notes are not accepted for exchange because of
an invalid tender, the occurrence of certain other events described in this
prospectus or otherwise, the certificates for any such unaccepted outstanding
notes will be returned, without expense, to the tendering holder as promptly as
practicable after the expiration date.

    Holders who tender their outstanding notes in the exchange offer will not be
required to pay brokerage commissions or fees or, subject to the instructions in
the letter of transmittal, transfer taxes in connection with the exchange of
outstanding notes in the exchange offer. We will pay all charges and expenses,
other than transfer taxes in certain circumstances, in connection with the
exchange offer. See "--Fees and Expenses."

INTEREST ON EXCHANGE NOTES

    Each exchange note will bear interest from May 17, 1999. Holders of the
outstanding notes whose outstanding notes are accepted for exchange will not
receive:

    - accrued interest on such outstanding notes for any period from and after
      the last interest payment date to which interest has been paid for on such
      outstanding notes prior to the original issue date of the exchange notes,
      or

    - if no such interest has been paid, will not receive any accrued interest
      on such outstanding notes, and will be deemed to have waived the right to
      receive any interest on such outstanding notes accrued from and after such
      interest payment date, or if no such interest has been paid or duly
      provided for, from and after May 17, 1999.

    Interest on the exchange notes will be payable semi-annually on May 1 and
November 1 of each year, commencing November 1, 1999.

PROCEDURES FOR TENDERING OUTSTANDING NOTES

    Only holders of outstanding notes may tender such outstanding notes in the
exchange offer. To tender in the exchange offer, a holder must:

    - complete, sign and date the letter of transmittal, or a facsimile of the
      letter of transmittal,

    - have the signatures guaranteed if required by the letter of transmittal,
      and

    - mail or otherwise deliver such letter of transmittal or such facsimile,
      together with the outstanding notes and any other required documents, to
      the exchange agent so as to be received by the exchange agent at the
      address set forth below prior to 5:00 p.m., New York City time, on the
      expiration date.

    Delivery of the outstanding notes may be made by book-entry transfer of such
outstanding notes into the exchange agent's account at The Depository Trust
Company in accordance with the procedures described below. Confirmation of such
book-entry transfer must be received by the exchange agent prior to the
expiration date.

    By executing the letter of transmittal, each holder will make to us the
representation described below in the first paragraph under the heading
"--Resale of Exchange Notes."

    The tender by a holder and our acceptance will constitute an agreement
between the holder and us in accordance with the terms and subject to the
conditions set forth herein and in the letter of transmittal.

    The method of delivery of outstanding notes and the letter of transmittal
and all other required documents to the exchange agent is at the election and
risk of the holder. Instead of delivery by mail, it is recommended that holders
use an overnight or hand delivery service. In all cases, sufficient time should
be allowed to assure delivery to the exchange agent before the expiration date.
No letter of transmittal or outstanding notes should be sent to us. Holders may
request their respective brokers, dealers, commercial banks, trust companies or
nominees to effect the above transactions on their behalf.

    Any beneficial owner whose outstanding notes are registered in the name of a
broker, dealer, commercial bank, trust company or other nominee and who wishes
to tender should contact the registered holder promptly and instruct such
registered holder to tender on such beneficial owner's behalf.

    Signatures on the letter of transmittal or a notice of withdrawal must be
guaranteed by an "eligible institution", which is defined below, unless the
outstanding notes tendered:

    - are signed by the registered holder, unless such holder has completed the
      box entitled "Special Exchange Instructions" or "Special Delivery
      Instructions" on the letter of transmittal, or

    - are tendered for the account of an eligible institution.

    In the event that signatures on a letter of transmittal or a notice of
withdrawal are required to be guaranteed, such guarantee must be by a member
firm of a registered national securities exchange or of the National Association
of Securities Dealers, Inc., a commercial bank or trust company having an office
or correspondent in the United States, or an "eligible guarantor institution"
within the meaning of Rule 17Ad-15 under the Securities Exchange Act. Any of the
entities described in the prior sentence is an eligible institution.

    If the letter of transmittal is signed by a person other than the registered
holder of any outstanding notes listed in that letter, the outstanding notes
must be endorsed or accompanied by a properly completed bond power, signed by
such registered holder as such registered holder's name appears on such
outstanding notes, with the signature guaranteed by an eligible institution.

                                       25
<PAGE>
    If the letter of transmittal or any outstanding notes or bond powers are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers or corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and unless waived by us,
evidence satisfactory to us of its authority to so act must be submitted with
the letter of transmittal.

    All questions as to the validity, form, eligibility, including time of
receipt, acceptance of tendered outstanding notes and withdrawal of tendered
outstanding notes will be determined by us in our sole discretion, which
determination will be final and binding. We reserve the absolute right to reject
any and all outstanding notes not properly tendered or any outstanding notes our
acceptance of which would, in the opinion of our counsel, be unlawful. We also
reserve the right to waive any defects, irregularities or conditions of tender
as to particular outstanding notes. Our interpretation of the terms and
conditions of the exchange offer, including the instructions in the letter of
transmittal, will be final and binding on all parties.

    Unless waived, any defects or irregularities in connection with tenders of
outstanding notes must be cured within such time as we shall determine. Although
we intend to notify holders of outstanding notes of defects or irregularities
with respect to tenders of outstanding notes, neither we nor the exchange agent
or any other person shall incur any liability for failure to give such
notification. Tenders of outstanding notes will not be deemed to have been made
until such defects or irregularities have been cured or waived. Any outstanding
notes received by the exchange agent that are not properly tendered and as to
which the defects or irregularities have not been cured or waived will be
returned by the exchange agent to the tendering holders, unless otherwise
provided in the letter of transmittal, as soon as practicable following the
expiration date.

BOOK-ENTRY DELIVERY PROCEDURES

    Promptly after the date of this prospectus, the exchange agent will
establish accounts with respect to the outstanding notes at The Depository Trust
Company, which will be the book-entry transfer facility for purposes of the
exchange offer. Any financial institution that is a participant in the
book-entry transfer facility systems may make book-entry delivery of the
outstanding notes by causing The Depository Trust Company to transfer such
outstanding notes into the exchange agent's account at such book-entry transfer
facility in accordance with such book-entry transfer facility's procedures for
such transfer. Timely book-entry delivery of outstanding notes pursuant to the
exchange offer, however, requires receipt of a confirmation of a book-entry
transfer prior to the expiration date. In addition, although delivery of
outstanding notes may be effected through book-entry transfer into the exchange
agent's account at the book-entry transfer facility, the letter of transmittal
or a manually signed facsimile of the letter of transmittal, together with any
required signature guarantees and any other required documents, or an agent's
message, which is defined below, in connection with a book-entry transfer, must
be delivered or transmitted to and received by the exchange agent at its address
set forth on the cover page of the letter of transmittal prior to the expiration
date to receive exchange notes for tendered outstanding notes, or the guaranteed
delivery procedure described below must be complied with. Tender will not be
deemed made until such documents are received by the exchange agent. Delivery of
documents to the book-entry transfer facility does not constitute delivery to
the exchange agent.

TENDER OF OUTSTANDING NOTES HELD THROUGH THE DEPOSITORY TRUST COMPANY

    The exchange agent and The Depository Trust Company have confirmed that the
exchange offer is eligible for The Depository Trust Company's Automated Tender
Offer Program. Accordingly, participants in The Depository Trust Company's
Automated Tender Offer Program may, instead of physically completing and signing
the applicable letter of transmittal and delivering it to the exchange agent,
electronically transmit their acceptance of the exchange offer by causing The
Depository Trust Company to transfer outstanding notes to the exchange agent in
accordance with The Depository Trust Company's Automated

                                       26
<PAGE>
Tender Offer Program procedures for transfer. The Depository Trust Company will
then send an agent's message to the exchange agent.

    The term agent's message means a message transmitted by The Depository Trust
Company, received by the exchange agent and forming part of the book-entry
confirmation, which states that The Depository Trust Company has received an
expressed acknowledgment from a participant in The Depository Trust Company's
Automated Tender Offer Program that is tendering outstanding notes which are the
subject of such book-entry confirmation, that such participant has received and
agrees to be bound by the terms of the applicable letter of transmittal or, in
the case of an agent's message relating to guaranteed delivery, that such
participant has received and agrees to be bound by the applicable notice of
guaranteed delivery, and that we may enforce such agreement against such
participant.

GUARANTEED DELIVERY PROCEDURES

    Holders who wish to tender their outstanding notes and:

        (1) whose outstanding notes are not immediately available;

        (2) who cannot deliver their outstanding notes, the letter of
    transmittal or any other required documents to the exchange agent; or

        (3) who cannot complete the procedures for book-entry transfer, prior to
    the expiration date, may effect a tender if:

            (a) the tender is made through an eligible institution;

            (b) prior to the expiration date, the exchange agent receives from
       such eligible institution a properly completed and duly executed notice
       of guaranteed delivery by facsimile transmission, mail or hand delivery
       setting forth the name and address of the holder, the certificate
       number(s) of such outstanding notes and the principal amount of
       outstanding notes tendered, stating that the tender is being made and
       guaranteeing that, within three (3) New York Stock Exchange trading days
       after the expiration date, the letter of transmittal or facsimile of the
       letter of transmittal, together with the certificate(s) representing the
       outstanding notes or a book-entry confirmation transfer of such
       outstanding notes into the exchange agent's account at The Depository
       Trust Company and all other documents required by the letter of
       transmittal, will be deposited by the eligible institution with the
       exchange agent; and

            (c) such properly completed and executed letter of transmittal or
       facsimile thereof, as well as the certificate(s) representing all
       tendered outstanding notes in proper form for transfer or a book-entry
       confirmation transfer of such outstanding notes into the exchange agent's
       account at The Depository Trust Company and all other documents required
       by the letter of transmittal, are received by the exchange agent within
       three (3) New York Stock Exchange trading days after the expiration date.

    Upon request to the exchange agent, a notice of guaranteed delivery will be
sent to holders who wish to tender their outstanding notes according to the
guaranteed delivery procedures described above.

WITHDRAWAL OF TENDERS

    Except as otherwise provided in this prospectus, tenders of outstanding
notes may be withdrawn at any time prior to 5:00 p.m., New York City time, on
the expiration date.

                                       27
<PAGE>
    To withdraw a tender of outstanding notes in the exchange offer, a written
or facsimile transmission notice of withdrawal must be received by the exchange
agent at the address set forth herein prior to 5:00 p.m., New York City time, on
the expiration date. Any such notice of withdrawal must:

    - specify the name of the person having deposited the outstanding notes to
      be withdrawn;

    - identify the outstanding notes to be withdrawn, including the certificate
      number(s) and principal amount of such outstanding notes, or, in the case
      of outstanding notes transferred by book-entry transfer, the name and
      number of the account at The Depository Trust Company to be credited;

    - be signed by the holder in the same manner as the original signature on
      the letter of transmittal by which such outstanding notes were tendered,
      including any required signature guarantees, or be accompanied by
      documents of transfer sufficient to have the trustee under the indenture
      register the transfer of such outstanding notes into the name of the
      person withdrawing the tender; and

    - specify the name in which any such outstanding notes are to be registered,
      if different from that of the depositor.

    We will determine all questions as to the validity, form and eligibility,
including time of receipt, of such notices. Our determination shall be final and
binding on all parties. Any outstanding notes so withdrawn will be deemed not to
have been validly tendered for purposes of the exchange offer and no exchange
notes will be issued unless the outstanding notes so withdrawn are validly
retendered. Any outstanding notes which have been tendered but which are not
accepted for exchange will be returned to such holder without cost as soon as
practicable after withdrawal, rejection of tender or termination of the exchange
offer. Properly withdrawn outstanding notes may be retendered by following one
of the procedures described above at any time prior to the expiration date.

CONDITIONS

    Despite any other term of the exchange offer, we shall not be required to
accept for exchange any outstanding notes, and may terminate or amend the
exchange offer as provided herein before the acceptance of such outstanding
notes, if:

        (a) in the reasonable opinion of our counsel, the exchange offer or any
    of its parts violates any applicable law or any applicable policy of the
    Commission;

        (b) any action or proceeding has been instituted or threatened in any
    court or by any governmental agency which might materially impair our
    ability to proceed with the exchange offer or any material adverse
    development has occurred in any such action or proceeding with respect to
    us;

        (c) any governmental approval has not been obtained, which approval we
    shall deem necessary for the consummation of the exchange offer as
    contemplated hereby; or

        (d) none of the outstanding notes have been duly tendered in accordance
    with the terms of the exchange offer.

EXCHANGE AGENT

    State Street Bank and Trust Company will act as exchange agent for the
exchange offer with respect to the outstanding notes.

                                       28
<PAGE>
    Questions and requests for assistance, requests for additional copies of
this prospectus or of the letter of transmittal for the outstanding notes and
requests for copies of the notice of guaranteed delivery should be directed to
the exchange agent, addressed as follows:

    By registered or certified mail or overnight courier:

        State Street Bank and Trust Company
       Corporate Trust Division
       P.O. Box 778
       Boston, MA 02102-0778

    Confirm by telephone: (617) 664-5587
                       Kellie Mullen

FEES AND EXPENSES

    We will pay the expenses of soliciting outstanding notes for exchange. The
principal solicitation is being made by mail by the exchange agent. However,
additional solicitations may be made by telephone, facsimile or in person by our
officers and regular employees and our affiliates and by persons so engaged by
the exchange agent.

    We will pay the exchange agent reasonable and customary fees for its
services and will reimburse it for its reasonable out-of-pocket expenses and pay
other registration expenses, including fees and expenses of the trustee under
the indenture, filing fees, blue sky fees and printing and distribution
expenses.

    We will pay all transfer taxes applicable to the exchange of the outstanding
notes pursuant to the exchange offer. If, however, certificates representing the
exchange notes or the outstanding notes for principal amounts not tendered or
accepted for exchange are to be delivered to, or are to be issued in the name
of, any person other than the registered holder of the outstanding notes
tendered, or if tendered outstanding notes are registered in the name of any
person other than the person signing the letter of transmittal, or if a transfer
tax is imposed for any reason other than the exchange of the outstanding notes
pursuant to the exchange offer, then the amount of any such transfer taxes,
whether imposed on the registered holder or any other person, will be payable by
the tendering holder.

ACCOUNTING TREATMENT

    The exchange notes will be recorded at the same carrying value as the
outstanding notes, which is the aggregate principal amount or accrued value, as
applicable, of the outstanding notes, as reflected in our accounting records on
the date of exchange. Accordingly, no gain or loss for accounting purposes will
be recognized in connection with the exchange offer. The expenses of the
outstanding notes offering and the exchange offer will be amortized over the
term of the exchange notes.

RESALE OF EXCHANGE NOTES

    Based on no-action letters issued by the staff of the Commission, we believe
that holders of the exchange notes issued pursuant to this exchange offer in
exchange for outstanding notes may offer for resale, resell and otherwise
transfer the exchange notes, other than such a holder who is a broker-dealer,
without further compliance with the registration and prospectus delivery
requirements of the Securities Act. This is true as long as such exchange notes
are acquired in the ordinary course of such holder's business and that such
holder is not participating, and has no arrangement or understanding with any

                                       29
<PAGE>
person to participate in a distribution within the meaning of the Securities Act
of such exchange notes. Despite the above, any holder of outstanding notes may
be subject to separate restrictions if it:

    - is our "affiliate" within the meaning of Rule 405 under the Securities
      Act;

    - does not acquire such exchange notes in the ordinary course of its
      business;

    - intends to participate in the exchange offer for the purpose of
      distributing exchange notes; or

    - is a broker-dealer who purchased such outstanding notes directly from us.

Holders of outstanding notes falling into any of the categories above:

    - will not be able to rely on the no-action letters of the staff of the
      Commission referred to above;

    - will not be permitted or entitled to tender such outstanding notes in the
      exchange offer; and

    - must comply with the registration and prospectus delivery requirements of
      the Securities Act in connection with any sale or other transfer of such
      outstanding notes unless such sale is made pursuant to an exemption from
      such requirements.

    Each broker-dealer that receives exchange notes for its own account in
exchange for outstanding notes, where those outstanding notes were acquired by
such broker-dealer as a result of market-making or other trading activities,
must acknowledge that it will deliver a prospectus in connection with any resale
of such exchange notes. The Commission has taken the position that
broker-dealers may fulfill their prospectus delivery requirements with respect
to exchange notes, other than a resale of an unsold allotment from the original
sale of the outstanding notes, with this prospectus. Under the registration
rights agreement, we are required during the period required by the Securities
Act to allow broker-dealers and other persons with similar prospectus delivery
requirements to use this prospectus in connection with the resale of such
exchange notes.

    In addition, as described below, if any broker-dealer holds outstanding
notes acquired for its own account, then such broker-dealer may be deemed a
statutory "underwriter" within the meaning of the Securities Act and must
deliver a prospectus meeting the requirements of the Securities Act in
connection with any resales of such exchange notes.

    Each holder of outstanding notes and each initial purchaser who is required
to deliver a prospectus in connection with sales or market making activities, by
acquisition of outstanding notes, agrees that, upon a receipt of notice from us
that:

        (1) the issuance by the Commission of any stop order suspending the
    effectiveness of the exchange offer registration statement under the
    Securities Act or of the suspension by any state securities commission of
    the qualification of the outstanding notes from offering or sale in any
    jurisdiction, or the initiation of any proceeding for any of the preceding
    purposes, or

        (2) the existence of any fact or the happening of any event that makes
    any statement of a material fact made in the registration statement or this
    prospectus, or any amendment or supplement to it or any document
    incorporated by reference herein untrue, or that requires the making of any
    additions or changes in the registration statement or this prospectus in
    order to make the statements in this prospectus, in light of the
    circumstances under which they were made, not misleading,

such holder or person shall discontinue disposition of the outstanding notes
pursuant to this prospectus until such holder or person has received copies of
the supplemented or amended prospectus or such holder or person is advised in
writing by us that use of the prospectus may be resumed and has received copies
of any additional or supplemental filings that are incorporated by reference in
the prospectus.

                                       30
<PAGE>
    In addition, each holder or person will be deemed to have agreed that it
will either:

        (1) destroy any prospectuses, other than permanent file copies, then in
    such holder or person's possession which have been replaced by us with more
    recently dated prospectuses; or

        (2) deliver to us, at our expense, all copies, other than permanent file
    copies, then in such holder's or person's possession of the prospectus
    covering such outstanding notes that was current at the time of receipt of
    the suspension notice regarding the happening of any event described in part
    (2) of the prior paragraph.

We shall extend the time period regarding the effectiveness of the registration
statement by a number of days equal to the number of days in the period from and
including the date of delivery of the suspension notice regarding the happening
of any event described in part (2) of the prior paragraph to the date of
delivery of the supplement or amendment.

CONSEQUENCES OF FAILURE TO EXCHANGE

    Any outstanding notes tendered and exchanged in the exchange offer will
reduce the aggregate principal amount of outstanding notes. Following the
consummation of the exchange offer, holders who did not tender their outstanding
notes generally will not have any further registration rights under the
registration rights agreement, and such outstanding notes will continue to be
subject to certain restrictions on transfer. Accordingly, the liquidity of the
market for such outstanding notes could be adversely affected.

    The outstanding notes are currently eligible for sale pursuant to Rule 144A
through Private Offerings, Resales and Trading through Automated Linkages
(PORTAL). Because we anticipate that most holders will elect to exchange such
outstanding notes for exchange notes in the exchange offer due to the absence of
restrictions on the resale of exchange notes, except for applicable restrictions
on any holder of exchange notes who is our affiliate or is a broker-dealer which
acquired the outstanding notes directly from us, under the Securities Act, we
anticipate that the liquidity of the market for any outstanding notes remaining
after the consummation of the exchange offer may be substantially limited.

    As a result of the making of this exchange offer, we will have fulfilled
certain of our obligations under the registration rights agreement, and holders
who do not tender their outstanding notes, with certain exceptions, will not
have any further registration rights under the registration rights agreement or
rights to receive liquidated damages for failure to register. Accordingly, any
holder that does not exchange its outstanding notes for exchange notes will
continue to hold the untendered outstanding notes and will be entitled to all
the rights and subject to all the applicable limitations under the indenture.

    The outstanding notes that are not exchanged for exchange notes pursuant to
the exchange offer will remain restricted securities within the meaning of the
Securities Act. Accordingly, such outstanding notes may be resold only:

    - to us or any of our subsidiaries;

    - inside the United States to a qualified institutional buyer in compliance
      with Rule 144A under the Securities Act;

    - inside the United States to an institutional "accredited investor", which
      term is defined in Rule 501(a)(1), (2), (3) or (7) under the Securities
      Act, an "accredited investor" that, prior to such transfer, furnishes or
      has furnished on its behalf by a U.S. broker-dealer to the trustee under
      the indenture a signed letter containing certain representations and
      agreements relating to the restrictions on transfer, the form of which
      letter can be obtained from such trustee;

    - outside the United States in compliance with Rule 904 under the Securities
      Act;

    - pursuant to the exemption from registration provided by Rule 144 under the
      Securities Act, if available; or

    - pursuant to an effective registration statement under the Securities Act.

                                       31
<PAGE>
    Each accredited investor that is not a qualified institutional buyer and
that is an original purchaser of any of the outstanding notes from the initial
purchaser will be required to sign a letter confirming that such person is an
accredited investor under the Securities Act and that such person acknowledges
the transfer restrictions summarized in this prospectus.

OTHER

    Participation in the exchange offer is voluntary and holders of outstanding
notes should carefully consider whether to accept the offer to exchange their
outstanding notes. Holders of outstanding notes are urged to consult their
financial and tax advisors in making their own decision on what action to take
with respect to the exchange offer. We may in the future seek to acquire
untendered outstanding notes in open market or privately negotiated
transactions, through subsequent exchange offers or otherwise. We have no
present plans to acquire any outstanding notes that are not tendered in the
exchange offer or to file a registration statement to permit resales of any
untendered outstanding notes.

           SELECTED CONSOLIDATED HISTORICAL FINANCIAL DATA OF ATRIUM
                       (AFTER THE 1998 RECAPITALIZATION)

    The selected consolidated historical income statement and other data set
forth below for the year ended December 31, 1995, the periods ended October 25,
1996 and December 31, 1996 and the years ended December 31, 1997 and 1998, and
the selected consolidated historical balance sheet data at December 31, 1995,
1996, 1997 and 1998 and October 25, 1996 were derived from the audited
consolidated financial statements described below. The selected consolidated
historical financial data as of and for the year ended December 31, 1994 and the
three months ended March 31, 1998 and 1999, were derived from Atrium's (after
the 1998 recapitalization) unaudited consolidated financial statements, which in
the opinion of management reflect all adjustments necessary for a fair
presentation of results for such periods. The selected consolidated historical
financial data should be read in conjunction with "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and the financial
statements, related notes and other financial information included elsewhere in
this prospectus.

    Prior to October 2, 1998, Atrium's consolidated historical financial
statements as filed with the Commission included its operations and the
operations of its subsidiaries. On October 2, 1998, pursuant to the 1998
recapitalization, the stock of Wing and Darby were contributed to Atrium.

    As Wing was determined to be the accounting acquiror in a "reverse
acquisition," the consolidated historical financial statements of Atrium, prior
to October 3, 1998, were replaced with the consolidated historical financial
statements of Wing. As a result, the selected consolidated historical income
statement and other data for 1998 includes the operations of Wing from January 1
through December 31 and the operations of Atrium and Darby from October 3
through December 31. The selected consolidated historical income statement and
other data for the three months ended March 31, 1999 include the operations of
Atrium, Wing and Darby for the three months ended March 31, 1999 and Delta since
January 27, 1999. Wing was acquired by its present controlling shareholders on
October 25, 1996. The selected consolidated historical income statement and
other data for the years ended December 31, 1994, 1995 and 1997, the three
months ended March 31, 1998 and the periods ended October 25, 1996 and December
31, 1996 only include the operations and accounts of Wing and its predecessor.
The December 31, 1998 selected consolidated historical balance sheet data
includes the accounts of Atrium, Wing and Darby. The December 31, 1994, 1995,
1996 and 1997, and October 25, 1996 selected consolidated historical balance
sheet data only include the accounts of Wing and its predecessor.

    The references in the selected consolidated historical financial data to the
periods ended December 31, 1996 and October 25, 1996, refer to the periods
October 26, 1996 through December 31, 1996 and January 1, 1996 through October
25, 1996, respectively.

</TABLE>

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

(1) EBITDA represents income before interest, income taxes, extraordinary
    charge, depreciation and amortization, special charges, stock option
    compensation expense and certain non-recurring expenses related to
    acquisitions. While we do not intend for EBITDA to represent cash flow from
    operations as defined by GAAP and we do not suggest that you consider it as
    an indicator of operating performance or an alternative to cash flow or
    operating income (as measured by GAAP) or as a measure of liquidity, we
    include it herein to provide additional information with respect to our
    ability to meet our future debt service, capital expenditures and working
    capital requirements. See "Management's Discussion and Analysis of Financial
    Condition and Results of Operations." We believe EBITDA provides investors
    and analysts in the building materials industry the necessary information to
    analyze and compare our historical results on a comparable basis with other
    companies on the basis of operating performance, leverage and liquidity.
    However, as EBITDA is not defined by GAAP, it may not be calculated on the
    same basis as other similarly titled measures of other companies within the
    building materials industry.

(2) For the purpose of calculating the ratio of earnings to fixed charges,
    earnings represent income (loss) before income taxes, extraordinary charge
    and fixed charges. Fixed charges consist of (1) interest, whether expensed
    or capitalized; (2) amortization of debt expense and discount or premium
    relating to any indebtedness, whether expensed or capitalized; and (3) that
    portion of rental expense considered to represent interest cost (assumed to
    be one-third). For the year ended December 31, 1998, earnings were
    insufficient to cover fixed charges by $2,329 which includes the effects of
    $3,851 of non-cash stock option compensation expense.

(3) On a pro forma basis, for the year ended December 31, 1998, earnings were
    insufficient to cover fixed charges by $166 and for the period ended March
    31, 1999 the ratio of earnings to fixed charges was 1.35x.

           SELECTED CONSOLIDATED HISTORICAL FINANCIAL DATA OF ATRIUM
                             (PREVIOUS REGISTRANT)

    The selected consolidated historical financial data set forth below for each
of the four years in the four-year period ended December 31, 1997 and as of and
for the period from January 1, 1998 to October 2, 1998, were derived from
Atrium's (previous registrant) audited consolidated financial statements. The
selected consolidated historical financial data as of and for the period ended
September 30, 1997 were derived from Atrium's (previous registrant) unaudited
consolidated financial statements, which in the opinion of the management affect
all the adjustments necessary for the fair presentation of results for such
period. The selected consolidated historical financial data should be read in
conjunction with "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and the financial statements, related notes and other
financial information included elsewhere in this prospectus.

    Prior to October 2, 1998, Atrium's historical financial statements as filed
with the Commission, included its operations and the operations of its
subsidiaries. On October 2, 1998, pursuant to the 1998 recapitalization, the
stock of Wing and Darby were contributed to Atrium.

    As Wing was determined to be the accounting acquiror in a "reverse
acquisition," the historical financial statements of Atrium (prior to October 3,
1998) were replaced with the historical financial statements of Wing. Therefore,
the selected consolidated historical financial data of Atrium (the previous
registrant) are provided for information purposes only.

    our historical results on a comparable basis with other companies on the
    basis of operating performance, leverage and liquidity. However, as EBITDA
    is not defined by GAAP, it may not be calculated on the same basis as other
    similarly titled measures of other companies within the building materials

             UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS

    Our unaudited pro forma consolidated financial statements are derived from
the audited and unaudited historical financial statements listed in the Index to
Financial Statements on page F-1 and certain unaudited financial statements of
other acquired businesses.

    Our unaudited pro forma consolidated financial statements have been prepared
to give effect to the transactions described below. As a result of the 1998
recapitalization, Wing is deemed to be the "accounting acquiror" in a reverse
acquisition transaction for financial statement purposes. As a result, our
historical consolidated statement of operations for the year ended December 31,
1998 includes Wing's operations for the entire year and only includes operations
for Atrium (previous registrant) and Darby from October 3, 1998 through December
31, 1998. The historical consolidated financial statements of operations for the
period ended March 31, 1999 includes the operations of Atrium for the three
months ended March 31, 1999, and the operations of Delta since it was acquired
on January 27, 1999.

    Our unaudited pro forma consolidated balance sheet as of March 31, 1999 has
been prepared to give effect to the Heat and Champagne acquisitions and the
offering of the outstanding notes and our use of the proceeds as if they
occurred on March 31, 1999. The assets and liabilities acquired have been
recorded at their estimated fair market values. Our unaudited pro forma
consolidated statement of operations for the year ended December 31, 1998 gives
effect to the Atrium transactions as if they occurred on January 1, 1998. Our
unaudited pro forma consolidated statement of operations for the three months
ended March 31, 1999 gives effect to the acquisitions of Delta, Heat and
Champagne and the offering of the outstanding notes and our use of the proceeds
as if they occurred on January 1, 1999.

    The unaudited pro forma adjustments are based upon available information and
certain assumptions that we believe are reasonable. Our unaudited pro forma
consolidated financial statements and the accompanying notes should be read in
conjunction with the historical financial statements listed in the Index to
Financial Statements on page F-1 and other financial information contained in
"Capitalization" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations" included elsewhere in this prospectus. Our
unaudited pro forma consolidated financial statements are not indicative of
either future results of operations or the results that might have occurred if
the Atrium transactions had been consummated on the indicated dates.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                             (DOLLARS IN THOUSANDS)

    The following discussion and analysis should be read in conjunction with the
consolidated financial statements of Atrium (after the 1998 recapitalization)
and Atrium (previous registrant) which appear elsewhere in this prospectus.

OVERVIEW

    GENERAL

    Atrium's (after the 1998 recapitalization) results are generally impacted by
the level of activity in the residential new construction and repair and
remodeling market segments throughout the United States. This activity is
influenced by regional and national economic trends, such as availability of
consumer credit, interest rates, job formation, age of housing stock,
inter/intra U.S. migration and consumer confidence.

    BACKGROUND

    Atrium was formed through a series of transactions and acquisitions. The
following summary should be considered in conjunction with reading the
information presented below:

    September 1, 1996--Atrium purchased certain assets of Keller Aluminum
Products of Texas, a division of Keller Building Products, which was owned by
Keller Industries, Inc. The assets were recorded at cost.

    September 30, 1996--Atrium Corporation acquired Atrium Door and Window
Company of the Northeast, formerly known as Bishop Manufacturing Company,
Incorporated, a manufacturer of vinyl replacement windows and doors for the
residential market in the northeast region of the United States. Atrium
Corporation contributed the capital stock of Atrium Door and Window Company of
the Northeast to Atrium. The transaction was recorded under the purchase method
of accounting.

    October 25, 1996--Wing Industries Holdings, Inc. acquired 100% of the
outstanding common stock of Wing Industries, Inc. and Wing Acquisition
Corporation, a Delaware corporation and a wholly owned subsidiary of Wing
Industries Holdings, was merged with and into Wing Industries, Inc. with Wing
Industries, Inc. being the surviving corporation. Wings Industries Holdings did
not have any significant activity prior to the acquisition of Wing. Wing
Industries, Inc. was founded in 1924 and incorporated in 1941. The acquisition
was accounted for under the purchase method of accounting.

    November 27, 1996--Atrium was effectively recapitalized in a transaction in
which affiliates of Hicks Muse Tate & Furst Incorporated purchased approximately
82% of Atrium Corporation's newly issued common stock and redeemed the equity
interests of selling security holders of Atrium. The redemption payments were
funded through the issuance of the existing senior subordinated notes and the
other outstanding debt of Atrium was refinanced. The transaction was accounted
for as a recapitalization.

    July 1, 1997--Atrium purchased the assets of the Western Window Division of
Gentek Building Products, Inc. Gentek, located in Anaheim, California is engaged
in the manufacture and sale of vinyl replacement windows to independent
remodelers and contractors. The acquisition was accounted for under the purchase
method of accounting.

    November 10, 1997--Wing Industries Holdings purchased certain assets of the
Door Division of Super Millwork, Inc. in a transaction accounted for under the
purchase method of accounting. The Door Division of Super Millwork, located in
Melville, New York, is engaged in the distribution, manufacture and sale of
doors and other millwork.

                                       47
<PAGE>
    January 8, 1998--Door acquired all of the outstanding common stock of R.G.
Darby Company, Inc. in a transaction accounted for under the purchase method of
accounting.

    March 27, 1998--Atrium purchased substantially all of the assets of
Masterview, a privately held window and door company located in Phoenix, Arizona
in a transaction accounted for under the purchase method of accounting.

    October 2, 1998--GEIPPPII, which was formed by GE Investment Management
Incorporated, a wholly-owned subsidiary of General Electric Company, and
Ardshiel, a private equity firm, and certain of its affiliates, acquired Atrium
in a transaction valued at $225,000. In connection with the Atrium acquisition,
GEIPPPII and an affiliate of Ardshiel recapitalized Wing and Darby and combined
them with Atrium.

    Prior to October 2, 1998, Atrium's historical financial statements as filed
with the Commission included its operations and the operations of its
subsidiaries. On October 2, 1998, pursuant to the 1998 recapitalization, the
stock of Wing and Darby were contributed to Atrium.

    As Wing was determined to be the accounting acquiror in a "reverse
acquisition," the historical financial statements of Atrium, prior to October 3,
1998, were replaced with the historical financial statements of Wing. As a
result, the statement of operations for 1998 includes the operations of Wing
from January 1 through December 31 and the operations of Atrium and Darby from
October 3 through December 31. The statements of operations for the years ended
December 31, 1994, 1995 and 1997 and the periods ended October 25, 1996 and
December 31, 1996 only include the operations and accounts of Wing and its
predecessor. Wing was acquired by its present controlling shareholders on
October 25, 1996.

    January 27, 1999--Atrium acquired certain assets of Delta, a privately held
door manufacturing and installation business located in Orlando, Florida. The
acquisition was accounted for under the purchase method of accounting.

    May 17, 1999--Atrium acquired Heat for approximately $85,000, including $700
of assumed indebtedness and Champagne for approximately $3,500, excluding $500
to be paid upon the achievement of certain operational results. The acquisition
was accounted for under the purchase method of accounting. Additionally, a post
closing adjustment of $3.5 million was paid on May 17, 1999 related to working
capital delivered in excess of the target defined in the Heat stock purchase
agreement.

INFLATION AND RAW MATERIALS

    During the past several years, the rate of general inflation has been
relatively low and has not had a significant impact on our results of
operations. We purchase raw materials, including aluminum, glass, wood and
vinyl, that are subject to fluctuations in price that may not reflect the rate
of general inflation. These materials fluctuate in price based on supply and
demand. Historically, there have been periods of significant and rapid aluminum
and wood price changes, both upward and downward, with a concurrent short-term
impact on our operating margins. We historically mitigated the effects of these
fluctuations over the long-term by passing through price increases to our
customers and through other means. For example, we enter into forward
commitments for aluminum billet to hedge against price changes. See the
footnotes to our consolidated financial statements for the year ended December
31, 1998. The primary raw materials used in the production of our windows and
doors are readily available and are procured from numerous suppliers. Currently,
wood is purchased through multiple sources from around the world, with little
dependence on one company or one country. See "Risk Factors--Fluctuations in Raw
Materials Costs and Supply; Reliance on Manufacturing Facilities and Suppliers."

</TABLE>

THREE MONTHS ENDED MARCH 31, 1999 COMPARED TO THREE MONTHS ENDED MARCH 31, 1998

    NET SALES.  Net sales increased by $67,392 from $39,450 during the first
quarter of 1998 to $106,842 during the first quarter of 1999. The increase was
primarily due to a combined increase in net sales of $65,400 from the addition
of Atrium and Darby in connection with the 1998 recapitalization and the
acquisition of Delta Millwork, Inc.

    COST OF GOODS SOLD.  Cost of goods sold decreased from 77.2% of net sales
during the first quarter of 1998 to 69.9% of net sales during the first quarter
of 1999. The decrease was due largely to the addition of Atrium and Darby, as
these divisions operate at higher gross profit margins than Wing.

    SELLING, DELIVERY, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, delivery,
general and administrative expenses increased $16,545 from $6,606 (16.7% of net
sales during the first quarter of 1998) to $23,151 (21.7% of net sales during
the first quarter of 1999). The increase was primarily due to the inclusion of
selling, delivery, general and administrative expenses of Atrium and Darby.
Additionally, delivery and selling expenses increased due to the increase in
sales.

    SPECIAL CHARGE.  We recorded a one-time charge of $1,762 for severance
benefits incurred in connection with the separation agreement entered into by
Atrium and the former President and Chief Executive Officer.

    INTEREST EXPENSE.  Interest expense increased $3,354 from $992 during the
first quarter of 1998 to $4,346 during the first quarter of 1999. The increase
in interest expense was due primarily to an increase in

                                       49
<PAGE>
average outstanding debt related to the issuance of term loan B and term loan C,
and the outstanding notes assumed in connection with the 1998 recapitalization.
In addition, interest expense included the amortization of deferred financing
costs recorded in connection with the 1998 recapitalization.

    INCOME TAXES.  Our 1998 effective tax rate increased from 44.8% to 81.3% due
largely to non-deductible goodwill amortization expense of approximately $1,150.
Excluding non-deductible amortization expense, our effective tax rate would have
been approximately 38.2%.

YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997

    NET SALES.  Net sales increased by $112,000 from $99,059 in 1997 to $211,059
in 1998. The increase was due primarily to a combined increase in net sales of
$87,909 from the addition of Atrium and Darby in connection with the 1998
recapitalization in October 1998 and the acquisition of Super Millwork in
November 1997. Additionally, net sales at Wing increased 24.3% due to an
increase in sales to home center retail chains.

    COST OF GOODS SOLD.  Cost of goods sold decreased from 79.0% of net sales
during 1997 to 75.4% of net sales during 1998. The decrease was due largely to
the addition of Atrium and Darby in the fourth quarter of 1998, as these
divisions operate at higher margins than Wing.

    SELLING, DELIVERY, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, delivery,
general and administrative expenses increased $24,083 from $15,671 (15.8% of net
sales during 1997) to $39,754 (18.8% of net sales during 1998). The increase was
primarily due to the inclusion of selling, delivery, general and administrative
expenses of Super Millwork for twelve months and Atrium and Darby for three
months. Additionally, selling and delivery expenses increased due to the
increase in net sales.

    AMORTIZATION EXPENSE.  Amortization expense increased $1,359 from $774
during 1997 to $2,133 during 1998. The increase was largely due to the
amortization of goodwill recorded in connection with the 1998 recapitalization.

    STOCK OPTION COMPENSATION EXPENSE.  Stock option compensation expense
increased $3,851 from $0 during 1997 to $3,851 during 1998. Stock option
compensation expense consisted of $2,813 representing the difference between the
fair market value of common stock of D and W Holdings and the exercise price
associated with a warrant granted to our executive in connection with the 1998
recapitalization, charges associated with previously issued stock options at
exercise prices below the fair value of the underlying common stock and charges
associated with certain variable options.

    INTEREST EXPENSE.  Interest expense increased $6,128 from $2,953 during 1997
to $9,081 during 1998. The increase in interest expense was due primarily to an
increase in average outstanding debt related to the loans issued and senior
subordinated notes assumed in connection with the 1998 recapitalization. In
addition, interest expense included the amortization of deferred financing costs
recorded in connection with the 1998 recapitalization.

    EXTRAORDINARY CHARGE.  Extraordinary charge increased $639 from $0 during
1997 to $639 during 1998. Extraordinary charge represents the write-off of
certain deferred financing costs incurred in the placement of Wing's debt, which
was repaid in connection with the 1998 recapitalization. This amount is net of
income tax benefit of $392.

YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996

    NET SALES.  Net sales increased by $22,979 from $76,080 in 1996 to $99,059
in 1997. The increase was primarily due to the increase in sales to the large
home center retail chains. The two largest home center retailers, which are
Wing's top two customers, have experienced sales growth in excess of 25%.
Additionally, the increase included $4,140 from the Super Millwork acquisition
in November 1997.

                                       50
<PAGE>
    COST OF GOODS SOLD.  Cost of goods sold increased from 75.2% of net sales
during 1996 to 79.0% of net sales during 1997. The increase is largely the
result of significant start-up costs incurred at the Cleveland prehanging
facility, the Allentown, Pennsylvania prehanging and hollow core manufacturing
facility and transition costs associated with moving a portion of the sales
volume attributable to the Super Millwork acquisition to the Allentown facility.

    SELLING, DELIVERY, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, delivery,
general and administrative expenses increased $158 from $15,513 (20.4% of sales
during 1996) to $15,671 (15.8% of sales during 1997). The decrease as a
percentage of sales is primarily attributable to lower freight costs per unit as
additional prehanging/distribution facilities are opened. Additionally, retail
store display expenses were reduced as a result of the implementation of a lower
cost display program.

    AMORTIZATION EXPENSE.  Amortization expense increased $649 from $125 during
1996 to $774 during 1997. The increase was due primarily to the amortization of
goodwill recorded in connection with the October 1996 acquisition of Wing.

    INTEREST EXPENSE.  Interest expense increased $2,070 from $883 during 1996
to $2,953 during 1997. The increase was due largely to an increase in average
outstanding debt which resulted from the incurrence of additional debt related
to the Wing acquisition in October 1996 and the Super Millwork acquisition in
November 1997, as well as borrowings under the Wing credit facility. Interest
expense during 1996 and 1997 includes amortization of related deferred financing
costs.

LIQUIDITY AND CAPITAL RESOURCES

    Cash generated from operations and availability under the revolving facility
are our principal sources of liquidity. During 1998, cash was primarily used in
connection with the 1998 recapitalization and for capital expenditures. Net cash
used in operating activities was $8,024 during 1998 compared to cash provided by
operations of $1,148 during 1997. The increase in cash used in operations was
primarily attributable to a decrease in net income and an increase in
inventories. Cash used for investing activities increased from $11,763 in 1997
to $125,184 in 1998. This increase was primarily the result of $120,977 for the
acquisition of Atrium. Cash flows from financing activities increased from cash
provided of $10,609 during 1997 to $133,174 during 1998. The increase was due
primarily to borrowings and contributions from Atrium Corporation made in
connection with the 1998 recapitalization.

    During the first quarter of 1999, cash was primarily used for increases in
working capital, capital expenditures and scheduled principal payments. Net cash
provided by operating activities was $680 during first quarter of 1999 compared
to cash used in operating activities of $486 during the first quarter of 1998.
The increase in cash provided by operating activities is largely due to an
increase in income before depreciation and amortization. Net cash used in
investing activities during the first quarter of 1999 was $3,363 compared to
$630 during the first quarter of 1998. The increase in cash used in investing
activities was due primarily to the acquisition of Delta and increased capital
expenditures. Cash provided by financing activities during the first quarter of
1999 and $2,683 compared to $1,363 during the first quarter of 1998, primarily
due to increased borrowings under the revolving credit facility.

    OTHER CAPITAL RESOURCES

    In connection with the 1998 recapitalization, we entered into a credit
facility providing for a revolving credit facility in the amount of $30,000, of
which $5,000 is available under a letter of credit sub-facility. The revolving
credit facility has a maturity date of June 30, 2004. At March 31, 1999, we had
$16,691 of availability under the revolving credit facility, net of borrowings
of $10,700 and outstanding letters of credit totaling $2,609. We used a portion
of the net proceeds of the offering of the outstanding notes to repay
approximately $8,100 outstanding under our revolving credit facility. In
connection with this offering, we increased the size of our revolving credit
facility from $30,000 to up to $40,000.

    CAPITAL EXPENDITURES

    We had cash capital expenditures, exclusive of the 1998 recapitalization, of
$2,221 during 1998, compared to $1,355 and $1,083 during 1997 and 1996,
respectively. The increase is largely due to the addition of Atrium and Darby
for the last three months of 1998. We expect capital expenditures, exclusive of
acquisitions, in 1999 to be approximately $9,500, however, actual capital
requirements may change, particularly as a result of acquisitions we may make.
Capital expenditures exclude costs related to the implementation of our new
management information system which include internally capitalized costs.

    We had cash capital expenditures of $1,059 during the first quarter of 1999
compared to $287 during the first quarter of 1998. The increase is largely due
to capital expenditures at Atrium and Darby. Actual capital expenditures during
the first quarter of 1999 exclude $158 in capitalized costs related to the
implementation of our new management information system.

    Our ability to meet our debt service and working capital obligations and
capital expenditure requirements is dependent, however, upon our and our
subsidiaries' future performance which, in turn, will be subject to general
economic conditions and to financial, business and other factors, including
factors beyond our control. As of March 31, 1999, we had $16,691 available for
borrowings under the revolving facility, net of borrowings of $10,700 and
outstanding and undrawn letters of credit totaling $2,609.

    AFTER THE ATRIUM TRANSACTIONS

    Historically, we have utilized internally generated funds and borrowings
under credit facilities to meet ongoing working capital and capital expenditure
requirements. In connection with the offering of the outstanding notes, we
incurred new indebtedness aggregating $172,368, net of $2,632 of unamortized
debt discount. The net proceeds of such indebtedness were used to finance the
acquisitions of Heat and Champagne, repay certain of our borrowings under our
credit facility (including accrued interest through date of payment), retire our
remaining existing senior subordinated notes (including accrued interest through
the date of repayment and repurchase premium), fund a distribution to Atrium
Corporation to repurchase a portion of the discount debentures (including
accreted discount through the date of repurchase) held by GEIPPPII and an
affiliate of Ardshiel and pay transaction fees and expenses.

    As a result of the Atrium transactions, we have significantly increased cash
requirements for debt service. We will rely on internally generated funds and,
to the extent necessary, on borrowings under our revolving credit facility to
meet our liquidity needs.

    Management believes that based on the current level of operations and
anticipated internal growth, cash flow from operations, together with
availability under our revolving credit facility, will be adequate to make
required payments of principal and interest on our indebtedness and to fund
anticipated capital expenditures and working capital requirements. However,
actual capital requirements may change. We may in the future seek additional
financing through the issuance of debt or equity. We cannot assure you that
additional financing, if needed, will be available to us on favorable terms, if
at all. Our ability to meet our debt service obligations and reduce our total
debt will be dependent on our future performance, which in turn, will be subject
to general economic conditions and to financial, business, and other factors,
including factors beyond our control. A portion of our debt bears interest at
floating rates; therefore, our financial condition is and will continue to be
affected by changes in prevailing interest rates. See "Risk Factors--Substantial
Leverage and Debt Service."

YEAR 2000

    Many existing computer systems and applications and other control devices
are coded to use only two digits, rather than four, to identify a year in the
date code field. These date code fields will need to accept four digit entries
to distinguish 21st century dates from 20th century dates. Many computer
programs and systems, including certain programs and systems utilized by us, are
highly dependent upon financial and

                                       52
<PAGE>
other data that, based on the program's or system's inability to distinguish
between the Year 2000 and other century-end dates, could be misreported or
misinterpreted and cause significant errors. If not corrected, many computer
applications could fail when processing data related to the Year 2000. In
addition, two interacting systems, applications or devices, each of which has
individually been fixed so that it will individually handle the Year 2000 issue,
could nonetheless suffer integration failure because their method of dealing
with the problem is not compatible.

    This Year 2000 issue impacts our owned or licensed computer systems and
equipment and the computer systems and equipment of third parties upon which we
rely. The Year 2000 problem could cause these systems to fail, err, and, in the
case of third party systems, become incompatible with our systems. Therefore, if
we, or a significant third party fail to become Year 2000 ready, or if the Year
2000 problem causes our systems to become internally incompatible or
incompatible with any key third party systems, our business could suffer
material disruptions.

    We are assessing the impact of the Year 2000 problem and have or intend to
modify portions of our hardware and software so that our computer systems will
function properly with respect to date in the Year 2000 and thereafter. We have
reviewed and continue to review each operating unit for the appropriate
information system enhancements, with respect to both Year 2000 problem as well
as strategic system upgrade.

    To achieve our overall operating strategy, we are enhancing our information
technology by installing new software to implement a fully integrated
manufacturing system for our operating units. This system has been certified by
the manufacturer as being Year 2000 compliant. Each operating unit was
prioritized for installation of the system based on any Year 2000 issues, with
the final phase of implementation and installation of this system scheduled to
be completed by the third quarter of 1999.

    We have inquired of our major suppliers and customers as to their Year 2000
compliance. Substantially all of our major suppliers and customers have
indicated that their Year 2000 testing and remediation programs are complete or
will be complete by the end of the third quarter. We have not, however, tested
or independently verified the Year 2000 compliance of our major suppliers and
customers.

    We face certain risks related to the Year 2000 problem including potential
disruptions in our operations due to Year 2000 problems with our systems,
potential disruptions in material supply due to Year 2000 problems with our
suppliers' systems and potential loss of sales or delayed cash collections in
the event of Year 2000 problems with our customers' systems. Although we have
not formalized a contingency plan to address the problems associated with these
risks, there are several factors that we believe may mitigate potential Year
2000 problems. Because our business has only recently been computerized, we
believe we can run our business without significant interruptions using manual
labor and "paper" systems in the event of a Year 2000 problem with our systems.
In addition, because we source our materials from several suppliers, we believe
we have decreased the likelihood that a Year 2000 disruption at one of our
suppliers will materially interrupt our material supply. Finally, because many
of our customers use "paper" systems, we believe a Year 2000 problem with a
customer's system would not materially impact our sales. Although we believe
these factors mitigate our Year 2000 risks, we cannot assure you that problems
arising from these risks will not have a material adverse effect on our
business, operating results or financial condition.

    We believe that with our strategy and completed installations, the Year 2000
problem will not pose significant operational problems for us. We cannot assure
you, however, that our computer systems or the computer systems of companies we
acquire or the computer systems of other companies with whom we conduct business
will be Year 2000 compliant prior to December 31, 1999 or that the inability of
any such systems to process accurately Year 2000 data will not have a material
adverse effect on our business, operating results or financial condition.

                                       53
<PAGE>
    The total amount of costs to be incurred by us to address these system
enhancements is estimated at $1,500. We have expensed approximately $1,100
through March 31, 1999.

FINANCIAL ACCOUNTING STANDARDS

    In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130 ("FAS 130") "Reporting Comprehensive
Income." FAS 130 requires that all items that are required to be recognized
under accounting standards as components of comprehensive income be reported in
a financial statement that is displayed with the same prominence as other
financial statements. FAS 130 is effective for financial statement periods
beginning after December 15, 1997. We adopted FAS 130 beginning January 1, 1998.
We had no comprehensive income for all periods presented prior to January 1,
1998.

    In March 1998, the Accounting Standards Executive Committee of the American
Institute of Certified Public Accountants Issued Statement of Position 98-1
("SOP 98-1") "Accounting for the Costs of Computer Software Developed or
Obtained for Internal Use" that is effective for reporting periods beginning
after December 15, 1998, but provides for earlier application if certain
conditions are met. We have applied the provisions of SOP 98-1 in our financial
statements for the year ended December 31, 1998 and its adoption had no material
effect on our consolidated financial position or results of operations.

    In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133 ("FAS 133") "Accounting for Derivative
Instruments and Hedging Activities" that is effective for all fiscal quarters of
fiscal years beginning after June 15, 1999. We will implement the provisions of
FAS 133 as required. The future adoption of FAS 133 in not expected to have a
material effect on our consolidated financial position or results of operations.

</TABLE>

PERIOD ENDED OCTOBER 2, 1998 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30, 1997

    NET SALES.  Net sales increased by $27,625 from $139,793 during the first
nine months of 1997 to $167,418 during the period ended October 2, 1998. The
increase was primarily due to sales from Atrium Door and Window Company-West
Coast and Atrium Door and Window Company of Arizona (Masterview), acquired in
July of 1997 and March of 1998, respectively. Additionally, Atrium (1)
experienced growth at the Atrium Wood division, which was selected to be the
supplier in a national patio door sales program beginning the third quarter of
1997, (2) the addition of a significant customer at our Atrium Wood division,
and (3) continued growth at Kel-Star Building Products.

    COST OF GOODS SOLD.  Cost of goods sold increased from 64.1% of net sales
during the first nine months of 1997 to 65.2% during the period ended October 2,
1998. The increase in cost of goods sold as a percentage of net sales during the
period ended October 2, 1998 was primarily due to an increase in raw material
and direct labor costs, which offset material usage improvements at Atrium Wood.

    SELLING, DELIVERY, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, delivery,
general and administrative expenses increased $4,590 from $33,114 (23.7% of net
sales) during the first nine months of 1997 to $37,704 (22.5% of net sales)
during the period ended October 2, 1998. The increase was primarily due to the
inclusion of selling, delivery, general and administrative expenses of Atrium
Door and Window Company of Arizona and Atrium Door and Window Company-West
Coast, as well as an increase in amortization expense related to software
implementation costs, resulting from additional amounts capitalized during 1997.
Additionally, selling and delivery expenses increased due to the increase in
sales.

                                       55
<PAGE>
    SPECIAL CHARGES.  Special charges of $7,452 during the period ended October
2, 1998 consisted of management bonuses, the write-off of certain covenants not
to compete and transaction expenses related to the 1998 recapitalization. There
were no special charges during the first nine months of 1997.

    STOCK OPTION COMPENSATION EXPENSE.  Stock option compensation expense
increased $5,010 from $255 during the first nine months of 1997 to $5,265 during
the period ended October 2, 1998. In 1998, stock option compensation expense
consisted of the amortization of deferred compensation charges related to
previously issued options, charges representing the increase in the underlying
stock value associated with certain variable options and the expense associated
with cash redemption of certain options resulting from the 1998
recapitalization. In 1997, stock option compensation expense related to
amortization of deferred compensation charges related to previously issued
options and the cash redemption of certain options issued to a former executive
of Atrium.

    INTEREST EXPENSE.  Interest expense increased $1,003 from $8,542 during the
first nine months of 1997 to $9,545 during the period ended October 2, 1998. The
increase was due to an increase in average outstanding debt related to the
$17,500 senior term loan issued in connection with the Masterview acquisition,
which took place on March 27, 1998.

    OTHER INCOME (EXPENSE).  Other income decreased $1,413 from other income of
$1,127 during the first nine months of 1997 to other expense of $286 during the
period ended October 2, 1998. The first nine months of 1997 includes an
insurance settlement of $1,193 from the business interruption portion of the
Company's insurance claim filed as a result of the January 1997 fire at the
Extruders facility.

    EXTRAORDINARY CHARGES.  Extraordinary charges of $3,525 during the period
ended October 2, 1998 represented the write-off of certain deferred financing
charges incurred in connection with the 1998 recapitalization. This amount is
net of income tax benefit of $2,164. There were no extraordinary charges during
the first nine months of 1997.

YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996

    NET SALES.  Net sales increased by $30,495 from $156,269 in 1996 to $186,764
in 1997. The increase was primarily due to the increase in sales of $19,708 at
our Atrium Door and Window of the Northeast, Kel-Star and Woodville Extruders
businesses, all of which were acquired during the second half of 1996, and
Atrium Door and Window-West Coast, acquired from Gentek, effective July 1, 1997.
Additionally, Atrium experienced slight growth at its distribution centers and
within its core manufacturing divisions, including significant growth at the
Atrium Wood division, which was awarded a national patio door sales contract
during the second quarter of 1997.

    COST OF GOODS SOLD.  Cost of goods sold decreased from 65.5% of net sales
during 1996 to 65.0% of net sales during 1997. The decrease was due largely to
on-going cost reductions at Atrium Wood, which were offset by start-up
inefficiencies at Kel-Star.

    SELLING, DELIVERY, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, delivery,
general and administrative expenses increased $9,671 from $34,815 (22.3% of
sales during 1996) to $44,486 (23.8% of sales during 1997). The increase was
largely due to the inclusion of twelve months of selling, delivery, general and
administrative expenses at the Atrium Door and Window Company of the Northeast,
Kel-Star, Woodville Extruders and Atrium Door and Window-West Coast businesses,
as well as amortization expense related to software implementation costs.
Additionally, delivery expenses were negatively affected during 1997 as a result
of a fire at the Woodville Extruders division in January.

    SPECIAL CHARGES.  Special charges during 1996 consisted of $3,044 in
management bonuses which were the result of the Hicks Muse transaction. There
were no special charges in 1997.

                                       56
<PAGE>
    STOCK OPTION COMPENSATION EXPENSE.  Stock option compensation expense
decreased $2,716 from $3,023 during 1996 to $307 during 1997. In 1997, stock
option compensation expense related to amortization of deferred compensation
charges related to previously issued options and the cash redemption of certain
options issued to a former executive of Atrium. In 1996, stock option
compensation expense consisted of charges associated with the granting of new
stock options at exercise prices below the fair value of the underlying common
stock and the expense associated with the cash redemption of certain options,
both resulting from the Hicks Muse transaction, and amortization of deferred
compensation charges related to previously issued options. Included in stock
option compensation expense during 1996 is $1,320 representing the difference
between the fair market value of common stock of Atrium Corporation and the
exercise price associated with a warrant granted to an executive of Atrium in
connection with the Hicks Muse transaction.

    INTEREST EXPENSE.  Interest expense increased $6,736 from $4,786 during 1996
to $11,522 during 1997. The increase was due largely to an increase in average
outstanding debt which resulted from the issuance of our existing senior
subordinated notes, which were issued in connection with the Hicks Muse
transaction, as well as borrowing under our previous credit facility. Interest
expense during 1997 includes amortization of the related deferred financing
costs.

    OTHER INCOME (EXPENSE), NET.  Other income (expense), net increased $1,270
from other expense of $182 in 1996 to other income of $1,088 in 1997. Other
income in 1997 includes an insurance settlement of $1,193. This settlement with
Atrium's insurance carrier resulted from the business interruption portion of
Atrium's insurance claim filed as a result of a fire at the Woodville Extruders
division in January 1997.

    EXTRAORDINARY CHARGE.  Extraordinary charge of $1,176 during 1996 represents
the write-off of certain deferred financing charges incurred in connection with
the Hicks Muse transaction, as all then outstanding debt was retired with a
portion of the proceeds from the issuance of our existing senior subordinated
notes. This amount is net of income tax benefit of $720.

THE COMPANY

    We are one of the largest manufacturers and distributors of residential
windows and doors in the United States based on 1998 pro forma net sales. We
offer a complete product line including aluminum, vinyl and wood windows and
doors to our customers, which include leading national homebuilders and home
center retailers. We have grown rapidly through a combination of internal growth
and complementary acquisitions. Pro forma for the transactions described in
"Unaudited Pro Forma Consolidated Financial Statements", we would have had net
sales and adjusted EBITDA of $123.3 million and $10.3 million, respectively, for
the three months ended March 31, 1999.

    Our acquisitions of Heat and Champagne are a continuation of our strategy to
become the largest nationwide manufacturer and distributor of residential
windows and doors. Heat is a leading regional manufacturer of residential vinyl
windows and patio doors, with a strong presence in the eastern and midwestern
repair and remodeling market segments and the northwestern new construction
market segment. The Heat acquisition strengthens our vinyl product offering,
enhances our nationwide presence and provides access to a proprietary
distribution network of 22 distribution centers. Champagne is a regional vinyl
window manufacturer located in Denver, Colorado. The Champagne acquisition
enhances our presence in the vinyl markets of Colorado, Kansas and Nebraska.

    We have a balanced business mix, as measured by management's estimates of
the percentage of pro forma net sales derived from the different products we
sell, market segments we serve and the material types we use in our products:

    Our balance between the repair and remodeling and new construction market
segments is particularly important as we estimate that sales to the repair and
remodeling market segment represented approximately 64% of window and door
industry dollar sales in 1998.

    We were founded in 1948 and we believe we are one of the two largest
manufacturers and distributors of residential non-wood windows and the third
largest manufacturer and distributor of residential doors in the United States
based on 1998 pro forma net sales. Our portfolio of products includes some of
the

                                       58
<PAGE>
industry's most recognized brand names including ATRIUM and WING. Our full
product line of aluminum, vinyl and wood windows and doors enables us to
differentiate ourselves from our competition, leverage our multi-channel
distribution system and be well positioned to benefit from shifts in product
preferences. Regional product preferences exist for aluminum, vinyl and wood
windows and doors, and a full product line is important to serve our national
customer base effectively. We pride ourselves on our ability to provide to our
nationwide customers the most suitable material based on varying regional
product preferences.

    We have 53 manufacturing facilities and distribution centers strategically
located in 24 states to service customers on a nationwide basis. We distribute
through multiple channels including direct distribution to large homebuilders
and independent contractors, one-step distribution through home centers and
lumberyards and two-step distribution to wholesalers and dealers who
subsequently resell to lumberyards, contractors and retailers. We believe that
our multi-channel distribution network allows us to reach the greatest number of
end customers and provide nationwide service to those customers.

    Our company is vertically integrated with operations that include:

    - The extrusion of aluminum and vinyl, which is utilized internally in our
      fabrication operations, or sold to third parties;

    - The manufacture and assembly of window and door units, including
      pre-hanging of doors, and the sale of such units to wholesalers,
      lumberyards, dealers, home centers and homebuilders;

    - A turn-key installation program for builders in which we supply and
      install many of our products, including windows and interior and exterior
      doors; and

    - The sale of finished products to homebuilders, remodelers and contractors
      through company-owned distribution centers located across the country.

    Our organic growth has exceeded growth rates for the window and door
industry by more than two times over the last three years in large part as a
result of our strategic positioning in such high growth markets as the southern
and western United States and our significant presence in the fast-growing home
center category. We have completed seven acquisitions since 1996 and we believe
that we are well-positioned to be a leader in the consolidation of the
residential window and door industry because of our size, rapid organic growth
and our ability to integrate acquisitions successfully.

COMPETITIVE STRENGTHS

    We believe that we have a competitive advantage in our markets due to our
following competitive strengths:

    - LEADING MARKET POSITIONS. We are one of the largest suppliers of
      residential windows and doors in the United States with a domestic market
      share of approximately 5%. We believe that we have a leading market
      position in the following key products based on management estimates:

    - STRONG BRAND NAME RECOGNITION. Our brands are well recognized in the
      building trade and are a distinguishing factor in customer selection. The
      ATRIUM brand of windows and patio doors has been in existence for over 20
      years and is recognized for its quality and value. In addition, we believe

                                       59
<PAGE>
      ATRIUM is among the most-recognized brand names in the aluminum and vinyl
      window market segments. Our WING brand of wood passage and bi-fold doors
      is highly recognized according to surveys of our home center customers. We
      believe there are significant opportunities to leverage our existing
      brands by targeting cross-selling opportunities and by re-branding certain
      products.

    - COMPLETE, HIGH-QUALITY PRODUCT OFFERING. We are one of the few suppliers
      with a complete line of residential windows and doors in the United
      States. The ability to source windows and doors from a single supplier is
      a cost-saving opportunity for national homebuilders and home centers. This
      distribution flexibility and nationwide presence distinguishes as a
      "one-stop" solution for customers' window and door needs. Examples of our
      high quality and customer service standards include our approximately 99%
      order fill rate and the recognition of our WING product line by Lowe's as
      Millwork Supplier of the Year for 1997.

    - MULTI-CHANNEL DISTRIBUTION NETWORK. We have a multi-channel distribution
      network that includes direct, one-step and two-step distribution as well
      as 30 company-owned distribution centers. Our distribution strategy
      maximizes our market penetration and reduces reliance upon any one
      distribution channel for the sale of our products. Furthermore, as a
      manufacturer and distributor of windows and doors for more than four
      decades, Atrium has developed long-standing relationships with key
      distributors in its markets. In each instance, we seek to secure a leading
      distributor in each of our markets. If we cannot secure a top-tier
      distributor in a desired geographic market, we will consider the
      acquisition or start up of our own distribution center.

    - ESTABLISHED AND DIVERSIFIED CUSTOMER BASE. We have developed strong
      relationships with our current customer base, which includes over 5,000
      active accounts. We have strong relationships with some of the leading
      companies in homebuilding, including D.R. Horton, Del Webb and Centex, and
      home center retailing, including The Home Depot and Lowe's. Our customers
      are geographically diversified and our sales are balanced between the
      repair and remodeling (approximately 58%) and new construction
      (approximately 42%) market segments, which provides increased stability to
      our business.

    - LOW COST, VERTICALLY INTEGRATED MANUFACTURER. We believe that we are one
      of the industry's lowest cost providers based on our strong operating
      margins relative to our competitors. Our vertically integrated structure
      enables us to control all facets of the production and sale of windows and
      doors, eliminating incremental outsourcing costs. For our window and patio
      door products, our integrated operations, including extrusion, fabrication
      and distribution enable us to reduce inventory, improve production
      scheduling and optimize quality control. For our wood door products, our
      expertise in fabricating, pre-hanging and distributing wood doors provides
      similar cost saving advantages and operating efficiencies.

BUSINESS STRATEGY

    Our goal is to increase revenue growth and profitability and to strengthen
our leadership position in the residential window and door industry through the
following initiatives:

    - ENHANCE NATIONWIDE PRESENCE. We will continue to focus our core efforts on
      maintaining and developing our nationwide market share, including
      enhancing our strong presence in our existing high growth markets such as
      the southern and western United States. Our recent acquisitions have
      helped to further our geographic coverage and, we believe, combined with
      the implementation of cross-selling initiatives, will continue to
      facilitate our growth. We will also seek to enhance our nationwide
      capabilities by selectively starting or acquiring operations that
      complement our geographic coverage and product offerings.

                                       60
<PAGE>
    - EXTEND AND CROSS-SELL PRODUCT OFFERINGS. We plan to take advantage of
      cross-selling opportunities by marketing doors to our traditional window
      customers and windows to our traditional door customers and adding
      additional styles and designs to address specific regional product
      preferences. In addition, we believe there are significant opportunities
      to cross-sell products, such as our expanded vinyl and millwork offerings,
      through our existing distribution channels. We also maintain training and
      incentive programs in order to ensure that our divisional sales forces
      market our complete product line of windows and doors.

    - CAPITALIZE ON ATRIUM BRAND NAME. We will seek to continue to leverage the
      strength of our nationally recognized ATRIUM brand name that has been in
      existence for over 20 years. We believe that leveraging the ATRIUM name
      across our products and on a nationwide scale will enhance our brand name
      recognition. For example, we see a significant opportunity in transferring
      the ATRIUM brand to recently acquired product lines. Further, we will
      continue trade advertising initiatives to maintain Atrium's high brand
      awareness in the industry.

    - CONTINUE TO PURSUE OPERATIONAL EFFICIENCIES. Our team of highly
      experienced managers seeks to achieve improvements by closely scrutinizing
      our operations and applying best practices and continuous improvement
      programs across all of our divisions. We have been successful in improving
      the efficiency and productivity of our operations by automating
      manufacturing processes, improving logistics, implementing a company-wide
      information system, successfully integrating acquisitions and leveraging
      working capital requirements. We plan to analyze additional opportunities
      to improve operational efficiencies, including integrating our wood
      products manufacturing facilities and aluminum extrusion operations,
      increasing capacity utilization at all our manufacturing facilities and
      leveraging our size to realize purchasing savings.

    - MAKE SELECTIVE STRATEGIC ACQUISITIONS. We have successfully consummated
      and integrated seven acquisitions since 1996, in each case lowering
      operating costs. We intend to take advantage of the fragmented market for
      window and door manufacturers by acquiring companies that present
      identifiable cost savings opportunities and add to our existing product
      lines, market share and geographic coverage. As we continue our
      acquisition program, we believe we can leverage our proven expertise in
      integrating acquisitions and maximizing cost savings and productivity
      enhancements. Additionally, we believe our size and national presence will
      be attractive to companies looking to combine with an industry leader.

INDUSTRY OVERVIEW

    In 1998, new construction spending in the United States totaled over $657.0
billion. Of the total new construction spending amount, residential new housing
spending totaled approximately $212.0 billion. Additionally, residential repair
and remodeling expenditures approximated $140.0 billion in 1998. In 1998, new
housing starts in the United States ranged from approximately 1.0 million to
approximately 1.5 million, of which approximately 1.2 million were single-family
homes and approximately 0.3 million were multi-family homes. Historical
residential repair and remodeling expenditures have demonstrated consistent
growth dynamics increasing from approximately $15.0 billion to approximately
$125.3 billion during the period from 1970 to 1997 and averaging a compound
annual growth rate of 8.2%.

    We believe that, in 1998, United States residential window and door
expenditures were approximately $10.0 billion, of which we estimate new
construction and remodel and replacement expenditures represented approximately
$3.6 billion and $6.4 billion, respectively. The individual market segments for
windows and doors are as follows:

    WINDOWS.  The domestic window market has grown to approximately 58.2 million
in unit sales in 1998, and has outpaced the growth in the domestic building
materials industry generally. The $6.5 billion residential window industry can
be divided into two end-use segments: new construction, an estimated 18.7
million windows shipped in 1998, and repair and remodeling, approximately 39.5
million windows sold in 1998. We believe that the repair and remodeling segment
will continue to experience strong growth due to the strength of sales of
existing homes and the increase in the average age of homes from 23 years to 28
years in the last decade.

                                       62

    DOORS.  According to F.W. Dodge, the U.S. residential exterior and interior
door market, which we estimate to be $3.5 billion, represents more than 58.0
million units annually. The residential door industry can be divided into two
principal market segments: new construction and repair and remodeling. We
estimate that interior doors sold to the repair and remodeling segment
constitute at least one-third of all interior door units sold in the United
States in 1998.

    We believe that we and four other market leaders represent approximately 44%
of window and door industry sales, while the remaining approximately 56% of
industry sales is comprised of over 600 smaller regional companies with average
annual sales of approximately $10.0 million to approximately $20.0 million. The
door and window industry has experienced significant consolidation in the last
24 months. We believe this consolidation trend favors companies like ours, with
nationwide capabilities to service large home centers and home builders, strong
brand names, the ability to provide a complete product line and economies of
scale in manufacturing, distributing and marketing. In addition to opportunities
presented by consolidation of the industry, industry growth has been driven by
the growth in the home center retailer category. The home center industry is one
of the fastest growing retail sectors in the United States. According to
National Home Center News, the U.S. retail home improvement market is expected
to grow from over $140.0 billion in 1998 to approximately $170.0 billion by the
year 2002.

PRODUCTS

    We are one of a few window and door manufacturers that offer a complete
product line that consists of a full range of aluminum, vinyl and wood windows
and doors. Our complete product line allows us to differentiate ourselves from
our competition, leverage our multi-channel distribution system and be
well-positioned to benefit from shifts in product preference. As significant
regional product preferences exist among aluminum, vinyl and wood, a full
product line is important to serve a national customer base effectively. We
estimate that approximately 55% of our 1998 pro forma net sales were derived
from the sale of windows, approximately 40% from the sale of doors, and
approximately 5% from the sale of other products and services.

    WINDOWS.  We had $271.9 million in pro forma net sales from the sale of
windows in 1998, representing approximately 4% of the total U.S. window market.
We estimate that our pro forma net sales from the sales of windows in 1998 were
comprised of approximately 55% from the sale of aluminum products, approximately
44% from vinyl products and approximately 1% from wood products. Our window
products include sliders, double hung, and casement products and are sold under
the ATRIUM and HR WINDOWS-TM- brand names. We sell our windows primarily to
building contractors and lumberyards through direct and one-step distribution.

    The demand for our aluminum, vinyl and wood products vary by region:

    - ALUMINUM--Aluminum windows are the product of choice in the southern
      United States due to the region's warmer weather and more value-conscious
      customers. Aluminum is the most appropriate fenestration material for the
      region because thermal efficiency is less important and the product is
      sold at a lower cost than either vinyl or wood.

                                       63
<PAGE>
    - VINYL--Demand for vinyl windows, particularly in colder climates, has
      significantly increased over the last five years as vinyl windows have
      gained acceptance as a substitute for wood windows. This trend has been
      strengthened as prices for vinyl windows have become more competitive with
      wood products and durability and energy efficiency have improved. We
      entered the vinyl window market in mid-1995 and have increased sales of
      vinyl windows by leveraging the ATRIUM brand name, leveraging our
      distribution channels and through acquisitions. The Heat acquisition
      increased our presence in the vinyl window business from approximately 9%
      to 24% of our 1998 pro forma sales.

    - WOOD--Wood windows have the highest thermal efficiency and highest cost
      compared to aluminum and vinyl. Accordingly, wood windows are in demand in
      colder regions and in higher end homes. The ATRIUM name gained wide
      recognition in the 1970s and 1980s through the success of our line of wood
      patio doors. In order to capitalize on this success, we added a wood
      window line in 1991 including aluminum-clad and primed wood windows and
      patio doors. We have made the strategic decision to minimize our
      participation in the wood window business as it is concentrated on the
      higher end of the wood window market which is not part of our core focus.

    DOORS.  We had $194.9 million in pro forma net sales from the sale of doors
in 1998, representing approximately 6% of the total U.S. door market. We
estimate that approximately 85% of our 1998 pro forma door sales were generated
from interior doors and 15% from exterior doors. Our door products are sold
under the ATRIUM, WING and SUPER MILLWORK-REGISTERED TRADEMARK- brand names. We
sell our doors primarily to home center retailers through one-step distribution.

    - INTERIOR DOORS--There are two broad categories of interior doors: bi-fold
      doors and passage doors. Bi-fold doors are hinged folding doors and
      passage doors are the traditional doors used to connect rooms. There are
      also two types of interior wood bi-fold doors and passage doors: solid
      wood doors and hollow core doors. Solid doors are made completely of wood
      while hollow core doors consist of two door facings glued to a wood frame
      and are hollow on the inside. Both solid wood and hollow core passage
      doors are sold one of two ways, either as slabs or as pre-hung units.
      Slabs refer to the door itself and pre-hung units refer to slab doors
      already hinged to a door frame at the factory.

    - EXTERIOR DOORS--Our exterior door product offering consists primarily of
      patio doors and pre-hung steel entry doors.

<TABLE>
<S>                      <C>                      <C>                      <C>
   [LOGO]                [LOGO]                   [LOGO]                                    [LOGO]
</TABLE>

    We estimate that approximately 45% of our 1998 door pro forma sales were
generated from the sale of pre-hung doors, 30% from solid wood doors, 10% from
hollow core doors and 15% from patio doors. We estimate that approximately 60%
of all passage doors sold through home center retailers in 1998 were sold as
pre-hung units, mainly because of the ease of installation for the
do-it-yourself consumer. We are one of the few vertically-integrated companies
that both manufactures and pre-hangs doors. We believe that sales of our
pre-hung door line will continue to grow and will represent a larger portion of
our total door sales in the future due to the increased demand from
do-it-yourself consumers.

    OTHER PRODUCTS AND SERVICES.  We had $26.3 million in pro forma net sales
from the sale of other products and services in 1998. Our other products include
cafe doors, columns and shutters. We manufacture two types of cafe doors as well
as louvered shutters. The shutters can be used both for interior and exterior
applications. Columns come in many styles and are purchased from domestic
suppliers.

                                       64
<PAGE>
    We also offer a turn-key total installation program for builders in which we
supply and install interior doors, exterior doors, mouldings, locks, hardware
and other products. This concept allows a developer to transfer the risk
associated with retaining reliable work crews and provides protection from cost
overruns. We believe that developers view this as a value added service and are
willing to pay a premium price for it.

    As a part of the Heat operations, we began selling vinyl decking and patio
enclosures sun rooms. These products are sold through our existing distribution
channels and are manufactured similarly to our existing products. Demand for
both products is growing and we expect to expand the product line in the future.

SALES, MARKETING AND DISTRIBUTION

    One of the key components of our marketing strategy is to capitalize on the
complementary nature of our distribution channels. Historically, the majority of
our window production has been sold to remodelers, homebuilders, lumberyards and
wholesalers, while home center retailers represented the primary distribution
channel for doors. We plan to broaden our product offerings principally by
marketing doors to our traditional window customers and windows to our
traditional door customers.

    We have a multi-channel distribution network that includes direct, one-step
and two-step distribution as well as 30 company-owned distribution centers. Our
distribution strategy maximizes our market penetration and reduces reliance upon
any one distribution channel for the sale of our products. Furthermore, as a
manufacturer and distributor of windows and doors for more than four decades, we
have developed long-standing relationships with key distributors in each of our
markets. In each instance, we seek to secure the leading distributors in each
market. If we cannot secure a top-tier distributor in a desired geographic
market, we will consider the acquisition or start up of our own distribution
center.

    We also sell windows to major home center retailers and smaller
regional-based retail centers. Although home centers have become more important
to us because they target the repair and remodeling market segment, they still
accounted for less than 20% of our total window pro forma net sales in 1998.

    We utilize the following distribution channels:

    - DIRECT DISTRIBUTION (34% OF OUR PRO FORMA NET SALES IN 1998). We sell our
      windows and doors directly to contractors, remodelers and other
      homebuilders without the use of an intermediary. By selling directly to
      builders, we are able to increase our gross profits while at the same time
      offering builders more favorable pricing.

    - ONE-STEP DISTRIBUTION (61% OF OUR PRO FORMA NET SALES IN 1998). We sell
      our finished windows to lumberyards, building products distributors, home
      centers, and company-owned distribution centers, which will then sell to
      contractors, homebuilders or remodelers. While it is not required that
      lumberyards or building products distributors carry our products on an
      exclusive basis, it is not unusual for them to do so. In addition, they
      generally purchase based on orders, keeping little or no inventory.
      One-step distribution tends to be used most often in metropolitan areas.

        We maintain company-owned distribution centers in key markets where
    available independent distributors are weak or where we have been unable to
    make adequate arrangements with existing distributors. Company-owned
    distribution centers essentially act as one-step distributors.

    - TWO-STEP DISTRIBUTION (5% OF OUR PRO FORMA NET SALES IN 1998). Two-step
      distribution is the selling of completed doors and windows to a wholesaler
      or distributor who then sells the products to lumberyards, building
      products retailers and home centers. These intermediaries will in turn
      sell the windows and doors to the homebuilders, homeowners or remodelers.
      The wholesalers and distributors tend to maintain product inventory in
      order to service the needs of their client base for small quantities.
      Essentially, these middlemen are more common in rural areas where
      customers generally do not represent sufficient volume to purchase from us
      directly.

    To enhance our market coverage and leverage our brand equity, we currently
market our windows and patio doors under primarily two brand names, ATRIUM and
H-R WINDOWS. Due to the fact that we enjoy such significant national name
recognition at both the building trade and consumer levels, we have chosen

                                       65
<PAGE>
to consolidate a significant portion of our product line under the ATRIUM name.
We have completed a phase out of our SKOTTY, BISHOP and GENTEK brands. We expect
to extend the ATRIUM brand to other products, as well as to appropriate product
lines acquired in the future.

    Our promotional efforts to our door and window customers are focused on
cooperative advertising programs which are offered to certain of our major
customers. This gives us exposure in our customers' local media, including
newspaper, radio and television, in order to generate sales at individual
locations. We also invest in in-store displays showing operating door units and
photographs of in-room settings in order to generate sales once customers are in
the stores. Product knowledge classes are held to inform store employees about
the features and benefits of each product. Award winning packaging and in-store
signage are used to further general awareness within the stores. We also offer
retailers a video showing how quickly a homeowner can install a bi-fold door
using only basic hand tools.

    WINDOWS.  We market our window products through a sales force consisting of
approximately 75 company salaried and commissioned sales representatives and
approximately 100 independent commissioned sales representatives. Each of our
divisions is supported by a sales manager, direct sales representatives and
independent representatives. The sales managers coordinate marketing activities
among both company and independent representatives. Our sales representatives
focus primarily on direct sales to homebuilders, remodelers and contractors,
while independent sales representatives sell to home centers, lumberyards and
wholesalers. In general, independent sales representatives carry our window and
door products on an exclusive basis, although they may carry other building
products from other manufacturers.

    DOORS.  Our ability to supply home center retailers with a complete line of
wood doors positions us to provide superior service and convenience to our
customers. The "one-stop shopping" we provide enables retailers to reduce their
transaction costs, as they have to pay only one invoice, work with one sales
representative, and schedule the receipt of goods with only one company. Our
goal is to be the "preferred supplier" for the door aisle of home center
retailers.

    For door sales we use an internal sales force. In addition, senior
executives are actively involved with both sales and customer service. This
group is segregated between national and regional accounts. Approximately 80% of
our 1998 pro forma net sales of doors are made to national retail home center
chains. The internal sales force was realigned in early 1995 reducing the sales
staff from 18 to 7 while increasing the number of merchandise managers. As a
result, we have a smaller, more focused sales force which is better structured
to give the home centers the attention required at the store level.

    To assist our internal sales force of seven individuals and provide better
service to our customers, we have over 20 merchandising managers. The
merchandising managers provide home center retailers with in-store services such
as product knowledge seminars, store product resets to straighten stock and fix
displays, sales analysis and in-store merchandising. They also work with the
retailers to resolve claims issues and to handle product returns. This is a
significant advantage to us as it is a level of service that few suppliers can
offer.

OPERATIONS

    We manufacture and sell our windows through a vertically integrated process
that includes:

    - The extrusion of aluminum and vinyl, which is utilized internally in our
      fabrication operations, or sold to third parties;

    - The manufacture and assembly of window and door units, including
      pre-hanging of doors, and the sale of such units to wholesalers,
      lumberyards, dealers, home centers and homebuilders;

    - A turn-key installation program for builders in which we supply and
      install many of our products, including windows and interior and exterior
      doors; and

    - The sale of finished products to homebuilders, remodelers and contractors
      through company-owned distribution centers located across the country.

                                       66
<PAGE>
    We realize many operational and cost benefits from our vertically integrated
window operations. By extruding aluminum and vinyl components in-house, we are
able to secure a low-cost, reliable source of extrusions, control product
quality and reduce inventory levels. The integration of extrusion and
fabrication operations gives us more control over our manufacturing costs. We
continually work to achieve cost savings through increased capacity utilization
at our efficient facilities, adoption of best practices, reduction of cost of
materials, rationalization of product lines and reduction of inventory.

    We continue to build on what we believe is our position as one of the
industry's lowest cost manufacturers. Because of the scale of our operations, we
are able to negotiate price concessions for our raw materials, including glass
and vinyl. This is an important consideration because, historically, total cost
of new materials typically comprises approximately 50% of our net sales.

    We have been manufacturing wood products in Texas since 1953 and today have
three primary manufacturing facilities in the state. As home centers such as The
Home Depot and Lowe's have expanded throughout the country, we have
strategically established eight manufacturing operations nationwide in order to
serve these customers more efficiently. We believe we are one of the only door
suppliers which can service the home centers on a national basis. As the home
centers continue to expand into new markets, we will consider opening new
facilities to serve these regions.

    As part of the integration of Wing and Atrium, the Atrium Wood patio door
division is merging its manufacturing, distribution and sales functions with
Wing. We are currently fitting a facility to locate all of Atrium Wood's and a
portion of Wing's manufacturing operations. Due to the fact that both divisions
sell over 80% of their products to the home centers, we believe significant
benefits can be realized from the synergies between the sales and distribution
functions of Atrium Wood and Wing. Both service the same customers and
distribute to the same retail locations. This integration is expected to be
completed during the fourth quarter of 1999.

COMPETITION

    The residential window and door industry is highly fragmented. With few
exceptions, competitors are privately-owned, regional companies with sales under
$100.0 million. On a national basis we compete with a few national companies in
different regions, products, distribution channels and price points, but do not
compete against any single company across all of these areas. We compete with
various other companies in specific regions within each market.

    - WINDOWS--ALUMINUM AND VINYL. Our major competitors for the sale of
      aluminum windows are Reliant Building Products, Inc. and Metal Industries,
      Inc. The market for vinyl windows and doors is comprised primarily of
      local and regional manufacturers as no dominant manufacturer operates on a
      national basis. Historically, demand for vinyl windows and doors has been
      concentrated in the colder regions of the United States. Our major
      competitors for the sale of vinyl windows are SilverLine Building Products
      and Nortek, Inc. in the Northeast, Simonton Windows in the Mid Atlantic
      and Southeast and Milgard Manufacturing Inc. in the Pacific Northwest. In
      addition, we compete with a number of regional manufacturers that sell
      directly to repair and remodeling contractors.

    - WINDOWS AND PATIO DOORS--WOOD. In the wood window and door market segment
      of the industry, two large manufacturers, Andersen Corporation and Pella
      Corporation, sell premium products on a national basis. Our wood windows
      and doors are sold at a medium price point and primarily through home
      centers throughout the United States and direct to builders. We have many
      competitors at our price point in the wood window and door market segment,
      including Kolbe & Kolbe Millwork Co. Inc. and Hurd Millwork Co. Inc.

    - DOORS. We estimate that approximately 60% of all interior passage doors
      sold through home centers are pre-hung. We expect this percentage to grow
      due to the convenience and ease of installation of pre-hung doors. The
      pre-hung door industry is very fragmented and consists primarily of
      hundreds of small companies that engage primarily in the assembly of doors
      and who have

                                       67
<PAGE>
      annual sales of $10.0 million to $30.0 million each. We believe that these
      companies are finding it increasingly difficult to compete due to their
      lack of manufacturing capability. Our key competitors are Premdor, Inc.
      and Jeld Wen, both of which manufacture and pre-hang doors. Other
      competitors include Steves and Sons and Haley Bros.

SEASONALITY

    The new home construction market and the market for external repairs and
remodeling in northern climates are seasonal, with increased related product
sales in the second and third quarters. The market for interior repairs and
remodeling in northern climates tends to grow in the first and fourth quarters.
Although this results in seasonal fluctuations in the sales of certain of our
products, the complementary nature of our window and door business' selling
seasons helps mitigate this seasonality. See "Risk Factors--Seasonality."

CYCLICALITY

    Demand in the window and door manufacturing and distribution industry is
influenced by new home construction activity. For the three months ended March
31, 1999, we estimate that approximately 42% of our pro forma net sales were
related to new home construction. Trends in the housing sector directly impact
our financial performance. Accordingly, the strength of the U.S. economy, the
age of existing home stock, job growth, interest rates, consumer confidence and
the availability of consumer credit, as well as demographic factors, such as the
migration of the population within the United States, have a direct impact on
our business. Cyclical declines in new housing starts may adversely impact our
business and we cannot assure you that any such adverse effects would not be
material. See "Risk Factors--Cyclicality."

EMPLOYEES

    We employ approximately 4,350 people, of whom approximately 4,300 are
employed at our manufacturing facilities and distribution centers and
approximately 50 are employed at corporate headquarters. Approximately 1,580 of
our hourly employees are covered by collective bargaining agreements. We entered
into collective bargaining agreements in 1998 with the United Needle and
Industrial Trade Employee Union, SWRJB, ACTWU, AFL-CIO-CLC, covering certain
employees at the Atrium Aluminum, H-R Windows, Atrium Wood and Extruders
manufacturing facilities. All of these collective bargaining agreements expire
in May, 2001. In addition, we have collective bargaining agreements with The
Sheet Metal International Association Local Union No. 54, due to expire on
September 30, 2001, for our Kel-Star operations and Local Union 2743, Southern
Council of Industrial Workers, Chartered By United Brotherhood of Carpenters and
Joiners of America, AFL/CIO, due to expire on October 6, 2001, for our Woodville
Extruders operations. There are no union affiliations in connection with any of
our other divisions or subsidiaries. We believe that our relationship with our
employees is good.

*   Leased from affiliates of certain stockholders. See "Certain Relationships
    and Related Transactions--Facility Leases."

    Additionally, we lease 22 distribution warehouses in 14 states for vinyl
window distribution with sites averaging 8,000 square feet.

    We maintain our corporate headquarters in Dallas, Texas. The facilities
provide approximately 11,000 square feet and are leased for a seven-year term
expiring in 2004.

    We believe that our manufacturing plants are generally in good operating
condition and are adequate to meet future anticipated requirements.

BACKLOG AND MATERIAL CUSTOMERS

    We have no material long-term contracts. Orders are generally filled within
5 to 7 days of receipt. Our backlog is subject to fluctuation due to various
factors, including the size and timing of orders for our products and is not
necessarily indicative of the level of future sales.

    Our sales are concentrated with one of the leading home center retailers,
The Home Depot. For the year ended December 31, 1998, The Home Depot accounted
for approximately 23% of our pro forma net sales. No other customer accounted
for more than 10% of our net sales.

GOVERNMENT REGULATION AND ENVIRONMENTAL MATTERS

    Our past and present operations and our assets are subject to extensive
federal, state, local and foreign environmental laws and regulations pertaining
to the discharge of materials into the environment, the handling and disposal of
wastes including solid and hazardous wastes, or otherwise relating to health,
safety and protection of the environment. We do not expect to make any
expenditures with respect to

                                       69
<PAGE>
ongoing compliance with these environmental laws and regulations that would have
a material adverse effect on our capital expenditures, results of operations, or
competitive position. However, the applicable requirements under the law may
change at any time.

    The nature of our operations and assets expose us to the risk of claims
under environmental, health and safety laws and regulations. We cannot assure
you that material costs or liabilities will not be incurred in connection with
such claims. We have been subject to such claims in the course of our
operations, and have made expenditures to address these known conditions in a
manner consistent with applicable laws and regulations. Based on our experience
to date, we do not believe that these existing claims will have any further
material adverse effect on our capital expenditures, earnings or competitive
position. We cannot assure you that the discovery of presently unknown
environmental conditions, changes in environmental claims that may involve
material, health, and safety laws and regulations or other unanticipated events
will not give rise to expenditures or liabilities.

    Prior to 1993 we received correspondence in which we were named as
potentially responsible parties at two Superfund sites, pursuant to
Comprehensive Environmental Response, Compensation and Liability Act or
comparable state statutes. In one instance, we have entered into a settlement
and in the other instance, the group of potentially responsible parties has
negotiated a proposed redemption plan which has been approved by the relevant
state agency and is being reviewed by the United States Environmental Protection
Agency. Based on the actions taken to date, and our current insurance coverage,
we believe that any liability associated with the Superfund sites does not
currently have or will not have a material adverse effect on our financial
condition or the results of operations. However, because Comprehensive
Environmental Response, Compensation and Liability Act provides for strict and
sometimes joint and several liability, we cannot assure you that the liabilities
in question will not result in material expenditures in the future.

LEGAL PROCEEDINGS

    We are involved from time to time in litigation arising in the ordinary
course of our business, none of which is expected, individually or in the
aggregate, to have a material adverse effect on us.

1998 STOCK OPTION PLAN

    The D and W Holdings, Inc. 1998 Stock Option Plan, or the 1998 plan, which
provides for the grant of options to purchase common stock of D and W Holdings
to key employees and eligible non-employees of D and W Holdings and its
subsidiaries, was adopted by D and W Holdings in connection with the 1998
recapitalization. The 1998 plan provides for the grant of options to purchase up
to 11,991,142 shares of D and W Holdings common stock. In connection with the
1998 recapitalization, D and W Holdings granted options to purchase 3,582,353
shares of its common stock to management of Darby and Wing in exchange for
outstanding options to purchase Darby and Wing stock. Options to purchase an
additional 8,153,588 shares of D and W Holdings common stock were granted to
management of D and W Holdings and its subsidiaries contemporaneously with the
1998 recapitalization. The 1998 plan was amended, among other things, in
connection with the consummation of the Heat and Champagne acquisitions to
increase the number of shares of D and W Holdings common stock issuable upon the
exercise of options under the 1998 plan by up to an additional 3,000,000 shares.
Options to purchase 1,790,000 shares of D and W Holdings common stock have been
issued in connection with this amendment.

    All options granted thus far are non-qualified options, which do not qualify
under Section 422. Options granted under the 1998 plan generally have a term of
ten years from the date of grant and vest in equal installments annually over
three to five years dependent on continued employment. No option is exercisable
until it has vested. Options granted upon consummation of the 1998
recapitalization in exchange for outstanding options of Darby and Wing continue
to vest on the schedule applicable to the exchanged options. Of the options
granted in connection with the 1998 recapitalization, options to purchase
993,115 shares of D and W Holdings common stock will vest only in connection
with a value event, which is defined in the 1998 plan.

    Options are not transferable other than in accordance with the laws of
descent and distribution. Upon termination for cause or voluntary termination by
the optionee without good reason all vested options will automatically expire.
Upon termination of employment for any other reason, the optionee will have the
right to exercise the vested portion of any option. Also, upon termination of an
optionee's employment for any reason, D and W Holdings will have the right to
purchase outstanding options and any shares of D and W Holdings common stock
held by the optionee as a result of the exercise of an option.

REPLACEMENT STOCK OPTION PLAN

    In addition to the 1998 plan, D and W Holdings adopted the D and W Holdings,
Inc. Replacement Stock Option Plan, or replacement plan, relating to certain
options to purchase D and W Holdings common stock which were granted in
replacement of outstanding options of Atrium Corporation in connection with the
1998 recapitalization. Under the replacement plan, options to purchase an
aggregate of 1,575,000 shares of D and W Holdings common stock were granted in
exchange for outstanding options of Atrium Corporation which were not cashed out
in the 1998 recapitalization. These options vest ratably over a period of five
years on each anniversary date of the grant and have an exercise price of $0.01
per share. The replacement plan was amended in connection with the consummation
of the Heat and Champagne acquisitions to increase the number of shares of D and
W Holdings common stock issuable upon the exercise of options under the
replacement plan by up to an additional 1,000,000 shares. Options to purchase
675,531 shares of D and W Holdings common stock were issued under the
replacement plan in exchange for outstanding options of Heat which were not
cashed out.

    Upon termination of an optionee's employment, D and W Holdings shall have
the right to repurchase from the optionee all or any portion of their
replacement options. Upon exercise of any vested portion of a replacement
option, D and W Holdings may require the optionee to execute a buy-sell
agreement containing provisions similar to the repurchase provisions described
above, as a condition to such option exercise.

    The replacement plan provides that all options granted are in the form of
nonqualified options, which are options that do not qualify for favored tax
treatment under Section 422 of the Internal Revenue Code.

                                       75
<PAGE>
The replacement options have a term of 20 years from the date of grant subject
to early termination in connection with termination of employment. No option is
exercisable until it is vested. Replacement options are not transferable other
than in accordance with the laws of descent and distribution by an optionee,
except that options may be transferred to an optionee's family members or
personal representative.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

THE STOCKHOLDERS AGREEMENT

    GEIPPPII, Ardshiel, and certain major stockholders of D and W Holdings, have
entered into a stockholders agreement, dated as of October 2, 1998, which
affects their relative rights as stockholders of D and W Holdings.

    Under the stockholders agreement, GEIPPPII has the right to designate one
director in the event there are less then seven directors, and two directors in
the event the board of directors consists of seven or more members. Ardshiel and
its affiliates, shall be entitled to designate up to six directors.

    Subject to certain exceptions, each of the major stockholders, except for
GEIPPPII has agreed not to sell, transfer or otherwise dispose of such
stockholder's equity securities of D and W Holdings and an affiliate of Ardshiel
has agreed not to sell, transfer or otherwise dispose of its discount
debentures. In the event that GEIPPPII intends to transfer its equity securities
or discount debentures, each of the other major stockholders or holders of
discount debentures will be entitled to purchase a pro rata portion of the
equity securities or discount debentures held by such major stockholder or
holder of discount debentures. However, in the event such sale, transfer or
disposition by GEIPPPII occurs within four years of the date of stockholders
agreement, the other major stockholders or holders of discount debentures, will
be obligated to sell all of their equity securities and/or all of their discount
debentures to the proposed transferee.

    Subject to certain conditions, Ardshiel and its affiliates may require that
GEIPPPII (1) sell or otherwise dispose of its equity securities and discount
debentures to any person who is not an affiliate of Ardshiel or (2) purchase all
of the other major stockholders' equity securities and discount debentures. In
addition, subject to certain exceptions, GEIPPPII and/or D and W Holdings have
the right to purchase from any selling major stockholder any or all equity
securities proposed to be sold to a third party by such selling major
stockholder.

    Pursuant to the terms of the stockholders agreement, D and W Holdings has
granted the major stockholders certain registration rights relating to any or
all shares of D and W Holdings common stock held by such major stockholder.

    The stockholders agreement provides that the prior written consent of
GEIPPPII is required for D and W Holdings to take certain enumerated actions.

MANAGEMENT AGREEMENT

    We are a party to a management agreement dated October 2, 1998, which was
amended on May 17, 1999 with D and W Holdings, Atrium Corporation and Ardshiel.
Under the management agreement, Ardshiel provides advisory services to D and W
Holdings and its subsidiaries with respect to business strategy, operations and
budgeting and financial controls in exchange for an annual fee of $1.9 million
plus expenses. Additionally, the management agreement provides that D and W
Holdings or its subsidiary must offer Ardshiel the opportunity to perform
investment banking services in connection with a sale or purchase of a business
or any financing prior to engaging another financial advisor. Ardshiel has the
right to receive a closing fee for its services in an amount not be greater than
2% of the total purchase or sale price for such business. The consent of
GEIPPPII is required prior to the payment by D and W Holdings or any of its
subsidiaries of any closing fees to Ardshiel where D and W Holdings or any of
its subsidiaries is paying similar fees to other entities for similar services.

    D and W Holdings paid a closing fee of approximately $3.4 million, plus fees
and expenses, after the consummation of the 1998 Recapitalization in connection
therewith. In addition, Ardshiel received an aggregate of approximately $1.3
million in fees in connection with the Heat and Champagne acquisitions.

                                       78
<PAGE>
The management agreement will remain in effect until October 2, 2008. The
agreement will be automatically renewed for one-year periods unless either party
gives written termination notice prior to the expiration of the initial or any
extended term.

BUY-SELL AGREEMENTS

    D and W Holdings entered into buy-sell agreements with certain members of
its management under which D and W Holdings may repurchase from those persons
all or any portion of their shares of D and W Holdings common stock for a
purchase price specified in these agreements after the termination of their
employment. Each agreement also provides for certain restrictions on transfer.

    In addition, the buy-sell agreements entered into with Messrs. Gilmer and
Darby provide that they will have the right to require D and W Holdings to
repurchase their shares if they are terminated for any reason other than for
cause and D and W Holdings does not exercise its right to purchase the shares.

THE DISCOUNT DEBENTURES

    In 1998, Atrium Corporation issued $80.6 million aggregate principal amount
at maturity of its discount debentures to GEIPPPII and an affiliate of Ardshiel
to fund a portion of the 1998 recapitalization. The issuance represented $45.0
million in gross proceeds to Atrium Corporation, See "Description of Certain
Indebtedness--Discount Debentures." We used a portion of the net proceeds of the
offering of the outstanding notes to fund a distribution of $20.6 million to
Atrium Corporation to repurchase a portion of the discount debentures, including
accreted discount, from GEIPPPII and an affiliate of Ardshiel.

    D and W Holdings has agreed to cause

    - us to make dividend payments to Atrium Corporation to enable it to make
      interest and principal payments on, or to repurchase, redeem or prepay the
      discount debentures, as long as we have funds legally available for the
      payment of such dividends and we are not prohibited from making such
      dividend payments by the terms of any contract to which we are a party,

    - Atrium Corporation, as long as Atrium Corporation is not prohibited from
      doing so by the terms of any contract to which it or D and W Holdings is a
      party, to pay interest and principal on, or to repurchase, redeem or
      repay, the discount debentures from the proceeds of any such dividend
      payment.

    GEIPPPII and an affiliate of Ardshiel that owns discount debentures may in
the future transfer discount debentures to third parties not affiliated with
Atrium Corporation.

INTERCOMPANY LOAN

    In connection with the 1998 recapitalization, Atrium Corporation issued to
us a $24.0 million subordinated intercompany note and we, in turn, used a
portion of the proceeds from our term loan under our credit facility to fund the
intercompany loan to Atrium Corporation. The intercompany loan to Atrium
Corporation bore interest at a rate of 5.66% per annum computed semiannually.
The intercompany loan was repaid in November 1998 with proceeds from the
issuance of discount debentures.

INDEMNIFICATION AGREEMENTS

    We entered into indemnification agreements with Jeff L. Hull and Louis W.
Simi, Jr. under which we agreed to indemnify them, if either of them becomes a
party to or other participant in any threatened, pending or completed action,
suit or proceeding relating to the fact that the person is or was our director,
officer, employee, agent or fiduciary. We expect to enter into similar
indemnification agreements with each of the remaining directors and executive
officers.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS

CREDIT FACILITY, AS AMENDED

    The following is a description of the general terms of the credit facility
that are included in the credit agreement, dated as of October 2, 1998 as
amended as of May 5, 1999 and as further amended as of June 11, 1999, among
Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated, as lead
arranger, syndication agent and documentation agent, BankBoston, N.A., as
administrative agent, Atrium Corporation, Atrium, the lenders, D and W Holdings
and the subsidiaries of Atrium, as guarantors. The following description does
not purport to be complete and is subject to the credit agreement and the other
documents entered into in connection with the credit agreement.

    The credit agreement provides for three separate facilities consisting of
two term loans referred to as term loan B and term loan C, and a revolving
credit facility with a letter of credit sub-facility. The revolving facility
together with the term loans are referred to in this prospectus as the credit
facility loans. Term loan B and term loan C are in the amount of $75.0 million
and $100.0 million, respectively, and have maturity dates of June 30, 2005 and
June 30, 2006, respectively. We used the term loans to finance the 1998
recapitalization. We repaid $29.1 million of the term loan C after the closing
of our credit facility and approximately $15.2 million of term loan B with a
portion of the net proceeds of the offering of the outstanding notes. Principal
payments of the term loans amortize on a quarterly basis, beginning in December
1998. The revolving facility is in the amount of $40.0 million, of which $7.5
million is available under a letter of credit sub-facility. The revolving
facility has a maturity date of June 30, 2004 and is available for working
capital purposes and permitted acquisitions.

    The loans bear interest at either (a) a "base rate" equal to the higher of
(i) the federal funds rate plus 0.500% per annum or (ii) the administrative
agent's prime rate, plus (A) in the case of the term loan B, 2.00%, (B) in the
case of the term loan C, 2.250% and (C) in the case of the revolving facility
1.625%, or (b) LIBOR plus (A) in the case of the term loan B, 3.00%, (B) in the
case of the term loan C, 3.250% and (C) in the case of the revolving facility,
2.625%. Beginning June 30, 1999, the revolving facility bears interest at a
variable leverage-based rate ranging from the "base rate" plus 0.375% to 1.625%
or LIBOR plus 1.375% to 2.625%.

    We pay a per annum commitment fee of 0.500% of the available unused
commitment under the revolving facility. Beginning June 30, 1999, the commitment
fee is calculated at a variable leveraged-based rate ranging from 0.250% to
0.500%. Such fees are payable quarterly in arrears and upon termination of the
revolving facility.

    All amounts outstanding under the credit facility are secured by (1) a
pledge of all of our and our subsidiaries' capital stock and intercompany notes
and (2) a security interest in substantially all of our, Atrium Corporation's
and our subsidiaries' properties and assets. Atrium Corporation and each of our
subsidiaries have unconditionally guaranteed all of our obligations under the
credit agreement.

    We are required to make a mandatory prepayment of the credit facility loans
in an amount equal to 75% of annual excess cash flow, which percentage may,
under certain circumstances, be reduced to 50%. In addition, subject to certain
exceptions, we are required to make a mandatory prepayment of the credit
facility loans in an amount equal to (1) 100% of the net proceeds of asset sales
and other asset dispositions, (2) 100% of the net proceeds of the issuance or
incurrence of debt or of any sale and leaseback for proceeds in excess of a
certain threshold, and (3) 50% of the net proceeds from any issuance of equity
securities in any public offering or private placement or from any capital
contribution. We are also required to make a mandatory prepayment of outstanding
amounts under the revolving facility when amounts exceed the commitment for the
revolving facility. We are permitted to make voluntary prepayments of all or any
portion of the credit facility loans in accordance with the terms of the credit
agreement, without penalty or premium. In addition, we may reduce the unutilized
portion of the commitments under the revolving facility in accordance with the
terms of the credit agreement, without penalty or premium.

                                       82

    The credit agreement requires us to comply with certain covenants, which
include limitations on indebtedness, liens and further negative pledges,
investments, contingent obligations, dividends, redemptions and repurchases of
equity interests, mergers, acquisitions and asset sales, capital expenditures,
sale leaseback transactions, transactions with affiliates, dividend and other
payment restrictions affecting subsidiaries, changes in business, amendment of
documents relating to other indebtedness and other material documents, creation
of subsidiaries, designation of designated senior indebtedness in respect of the
outstanding notes and the exchange notes, and prepayment or repurchase of other
indebtedness. The credit agreement requires us to meet certain financial tests
pertaining to interest coverage, fixed charge coverage and leverage.

DISCOUNT DEBENTURES

    In 1998, Atrium Corporation issued approximately $80.6 million aggregate
principal amount at maturity of the discount debentures to GEIPPPII and an
affiliate of Ardshiel to finance in part the 1998 recapitalization. The issuance
represented $45.0 million in gross proceeds to Atrium Corporation. The following
is a summary of the principal terms of the discount debentures.

    The discount debentures were issued under an indenture, dated as of October
2, 1998 between Atrium Corporation and United States Trust Company of New York,
as Trustee.

    TERMS OF THE DISCOUNT DEBENTURES.  The discount debentures were issued at an
original issue discount and are unsecured senior obligations of Atrium
Corporation limited to approximately $80.6 million aggregate principal amount at
maturity. The discount debentures rank equal in right of payment with other
senior unsecured indebtedness of Atrium Corporation and senior to any
subordinated obligations of Atrium Corporation. The discount debentures will
mature on October 1, 2010. No cash interest will accrue on the discount
debentures prior to October 1, 2003. After that date, cash interest will accrue
on the discount debentures at an annual rate of 12%, payable semiannually on
April 1 and October 1 of each year. Prior to October 1, 2003, Atrium Corporation
may elect to commence the accrual of cash interest from any interest payment
date. In such case, the principal amount at maturity will be reduced to the
accreted value of the discount debentures on such date, and cash interest will
then accrue and be payable.

    REDEMPTION.  The discount debentures will not be redeemable at the option of
Atrium Corporation prior to October 1, 2003. After that date, the discount
debentures will be redeemable, at Atrium Corporation's option, in whole or in
part, at 106% of the accreted value of the discount debentures so redeemed,
together with accrued and unpaid interest to the redemption date. In addition,
before October 1, 2001, Atrium Corporation may redeem all of the discount
debentures at 112% of accreted value plus accrued and unpaid interest to the
redemption date, with the net proceeds of one or more equity offerings.

    CHANGE OF CONTROL.  Upon the occurrence of a change of control each holder
of the discount debentures will have the right to require that Atrium
Corporation repurchase such holder's discount debentures at a purchase price in
cash equal to 101% of the accreted value plus accrued and unpaid interest to the
date of repurchase. In addition, at any time prior to October 2, 2003, Atrium
Corporation may redeem the discount debentures as a whole following a change of
control at a redemption price equal to 100% of the accreted value plus the
applicable premium and accrued and unpaid interest to the redemption date.

    A portion of net proceeds of the offering of the outstanding notes was used
to distribute $20.6 million, including accreted discount, to Atrium Corporation
to repurchase a portion of the discount debentures.

    GEIPPPII and an affiliate of Ardshiel that owns discount debentures may in
the future transfer discount debentures to third parties not affiliated with
Atrium Corporation.

                       DESCRIPTION OF THE EXCHANGE NOTES

GENERAL

    The outstanding notes were issued and the exchange notes will be issued
under an indenture, dated as of May 17, 1999, among Atrium, the subsidiaries of
Atrium, as guarantors and State Street Bank and Trust Company, as trustee. Upon
the issuance of the exchange notes, the indenture will be governed by the Trust
Indenture Act of 1939, as amended.

    The following summary of certain provisions of the indenture and the
exchange notes is not complete and is subject to all the provisions of the
indenture and the exchange notes.

    You can find the definition of certain terms used in the following summary
under the subheading "--Certain Definitions."

    In this description of the exchange notes, references to Atrium refer to
Atrium Companies, Inc. and not to any of its subsidiaries.

    Principal, premium, and interest on the exchange notes will be payable, and
the exchange notes may be exchanged or transferred, at the office or agency of
Atrium in the Borough of Manhattan, The City of New York, which initially shall
be the corporate trust office of the trustee in New York, New York. Payment of
interest may be made by check. Initially, the trustee will act as paying agent
and registrar for the exchange notes. The exchange notes may be presented for
registration of transfer and exchange at the offices of the registrar.

    The exchange notes will be issued only in fully registered form, without
coupons, in denominations of $1,000 and any integral multiple of $1,000. No
service charge will be made for any registration of transfer or exchange of
exchange notes, but Atrium may require payment of a sum sufficient to cover any
transfer tax or other similar governmental charge payable in connection with
such transfer or exchange.

TERMS OF EXCHANGE NOTES

    The exchange notes will be unsecured, senior subordinated obligations of
Atrium, which are limited to $175,000,000 aggregate principal amount. The
exchange notes will mature on May 1, 2009. Each exchange note will bear interest
at the rate of 10 1/2% per annum from May 17, 1999, and will be payable
semiannually on May 1 and November 1 of each year, commencing on November 1,
1999. The exchange notes will not be entitled to the benefit of any mandatory
sinking fund.

OPTIONAL REDEMPTION

    OPTIONAL REDEMPTION.  The exchange notes are not redeemable prior to May 1,
2004.

    The exchange notes will be redeemable at the option of Atrium, in whole or
in part, at any time on or after May 1, 2004, at the redemption prices,
expressed as percentages of the principal amount set forth below, plus accrued
and unpaid interest thereon, if any, to the date of redemption, if redeemed
during the 12-month period beginning on May 1 of the years indicated:

</TABLE>

    OPTIONAL REDEMPTION UPON EQUITY OFFERING.  On or prior to May 1, 2002,
Atrium may, at its option, use the net proceeds of one or more Equity Offerings
following which there is a Public Market to redeem up to

                                       84
<PAGE>
35% of the originally issued aggregate principal amount of the exchange notes,
at a redemption price in cash equal to 110.5% of the principal amount thereof,
plus accrued and unpaid interest thereon, if any, to the date of redemption;
PROVIDED that

    - at least 65% of the originally issued aggregate principal amount of
      exchange notes is outstanding following such redemption; and

    - notice of such redemption must be given not later than 60 days after the
      consummation of any such Equity Offering.

    OPTIONAL REDEMPTION UPON CHANGE OF CONTROL.  At any time on or prior to May
1, 2004, the exchange notes may be redeemed as a whole and not in part at the
option of Atrium upon the occurrence of a Change of Control, at a redemption
price equal to 100% of the principal amount thereof plus the Applicable Premium
and accrued and unpaid interest, if any, to, the date of redemption. Notice of
such redemption must be given not later than 90 days after the occurrence of
such Change of Control.

    SELECTION AND NOTICE.  In the event that less than all of the exchange notes
are to be redeemed selection of exchange notes for redemption will be made by
the trustee in compliance with the requirements of the principal national
securities exchange on which the exchange notes as follows are listed; or if the
exchange notes are not listed on a national securities exchange, selection will
be made on a PRO RATA basis or by such method as the trustee will deem fair and
appropriate.

    No exchange notes of a principal amount of $1,000 or less shall be redeemed
in part. Any redemption made with the net proceeds of an Equity Offering will be
made on a PRO RATA basis or on as nearly a PRO RATA basis as practicable.

    Notice of redemption shall be mailed by first class mail at least 30 but not
more than 60 days before the redemption date to each holder of exchange notes to
be redeemed at its registered address.

    If any exchange note is to be redeemed in part only, the notice of
redemption that relates to that exchange note will state the portion of the
principal amount to be redeemed. A new exchange note in a principal amount equal
to the unredeemed portion of the original exchange note will be issued in the
name of the holder thereof upon cancellation of their original exchange note. On
and after the redemption date, interest will cease to accrue on exchange notes
or portions called for redemption.

RANKING AND SUBORDINATION

    The payment of the principal, premium and interest on the exchange notes is
subordinated in right of payment to the payment of all Senior Indebtedness of
Atrium. However, payment of Permitted Junior Securities and payment from the
money or the proceeds of U.S. Government Obligations held in any defeasance
trust described under "--Defeasance" below is not subordinate to any Senior
Indebtedness. Assuming that the Atrium transactions occurred on March 31, 1999,
Atrium would have had approximately $136.6 million of Senior Indebtedness
outstanding, exclusive of unused commitments under our revolving credit
facility, and the Guarantors would have had approximately $1.3 million of Senior
Indebtedness outstanding, exclusive of their guarantee of approximately $135.3
million of our Senior Indebtedness.

    Only Indebtedness of Atrium that is Senior Indebtedness will rank senior to
the exchange notes in accordance with the provisions of the indenture. The
exchange notes will in all respects rank equally with all other Senior
Subordinated Indebtedness of Atrium. The exchange notes will rank senior to all
Subordinated Obligations of Atrium.

    Atrium may not pay principal, premium or interest on the exchange notes or
make any deposit pursuant to the provisions described under "--Defeasance" and
may not otherwise purchase or retire any exchange notes (collectively, "pay the
exchange notes") if

        (1) any Designated Senior Indebtedness is not paid when due or

                                       85
<PAGE>
        (2) any other default on Designated Senior Indebtedness occurs and the
    maturity of such Designated Senior Indebtedness is accelerated, unless the
    default has been cured or waived and/or any such acceleration has been
    rescinded or such Designated Senior Indebtedness has been paid in full;

    PROVIDED, HOWEVER, Atrium may pay the exchange notes if Atrium and the
trustee receive written notice approving such payment from the Representative of
such Designated Senior Indebtedness.

    During the continuance of any default, with the exception of a default
described in clause (1) or (2) of the preceding sentence, with respect to any
Designated Senior Indebtedness pursuant to which the maturity thereof may be
accelerated immediately or the expiration of any applicable grace periods,
Atrium may not pay the exchange notes for a period (a "Payment Blockage Period")
commencing upon the receipt by the trustee of written notice (a "Blockage
Notice") of such default from the Representative of the holders of such
Designated Senior Indebtedness. Such Blockage Notice should specify an election
to effect a Payment Blockage Period and ending 179 days thereafter or earlier if
such Payment Blockage Period is terminated;

        (1) by written notice to the trustee and Atrium from the Person or
    Persons who gave such Blockage Notice,

        (2) because the default giving rise to such Blockage Notice is no longer
    continuing, or

        (3) because such Designated Senior Indebtedness has been repaid in full.

    Atrium may resume payments on the exchange notes after the end of such
Payment Blockage Period. Not more than one Blockage Notice may be given in any
consecutive 360-day period and there shall be a period of at least 180
consecutive days in each 360-day period when no Payment Blockage Period is in
effect.

    Upon a total or partial liquidation or dissolution or reorganization or
bankruptcy of or similar proceeding relating to Atrium or its property, the
holders of Senior Indebtedness will be entitled to receive payment in full of
the Senior Indebtedness before the holders of the exchange notes. If a
distribution is made to holders of the exchange notes that, due to the
subordination provisions, should not have been made to them, such holders are
required to hold it in trust for the holders of Senior Indebtedness and pay it
over to them as their interests may appear. In the event of insolvency,
creditors of Atrium who are holders of Senior Indebtedness may recover more,
ratably, than the holders of exchange notes, and creditors of Atrium who are not
holders of Senior Indebtedness, including holders of the exchange notes.

GUARANTEES

    Each Guarantor fully and unconditionally guarantees, jointly and severally,
to each holder and the trustee, on a senior subordinated basis, the full and
prompt payment of principal of, premium, if any, and interest on the exchange
notes, and of all other obligations of Atrium under the indenture.

    The Indebtedness evidenced by each Guarantee, including the payment of
principal of, premium, if any, and interest on the exchange notes, will be
subordinated to Senior Indebtedness of each such Guarantor on substantially the
same basis as the exchange notes are subordinated to Senior Indebtedness of the
Guarantor. As of March 31, 1999, on a pro forma basis after giving effect to the
Atrium transactions, the Guarantors would have had approximately $135.3 million
of Senior Indebtedness outstanding exclusive of the guarantees of the Guarantors
under the Credit Facility.

    The obligations of each Guarantor are limited to the maximum amount as will
result in the obligations of such Guarantor under the Guarantee not constituting
a fraudulent conveyance or fraudulent transfer under federal or state law. Each
Guarantor that makes a payment or distribution under a Guarantee shall be
entitled to contribution from each other Guarantor in a PRO RATA amount based on
the Adjusted Net Assets of each Guarantor.

                                       86
<PAGE>
    Subject to the requirements described under "--Certain
Covenants--Consolidation, Merger, Sale of Assets, Etc.," any Guarantee by a
Restricted Subsidiary of the exchange notes shall provide by its terms that it
shall be automatically and unconditionally released and discharged upon any
sale, exchange or transfer to any Person not an Affiliate of Atrium of all of
Atrium's Capital Stock or all or substantially all the assets of such Restricted
Subsidiary, which transaction is in compliance with the terms of the indenture.
Such Guarantee will be released and discharged so long as such Restricted
Subsidiary has been or simultaneous with its release under the Guarantee will be
unconditionally released from all guarantees by it of other Indebtedness of
Atrium or any Restricted Subsidiary. Atrium may, at any time, cause a Subsidiary
to become a Guarantor by executing and delivering a supplemental indenture
providing for the guarantee of payment of the exchange notes by such Subsidiary.

CHANGE OF CONTROL

    Upon the occurrence of a Change of Control, each holder will have the right
to require Atrium to repurchase all or any part of such holder's exchange notes
at a purchase price in cash equal to 101% of the principal amount thereof plus
accrued and unpaid interest, if any, to the date of purchase.

    Within 30 days following any Change of Control Atrium shall mail a notice
(the "Change of Control Offer") to each holder with a copy to the trustee
stating:

        (1) that a Change of Control has occurred and that such holder has the
    right to require Atrium to purchase such holder's exchange notes at a
    purchase price in cash equal to 101% of the principal amount thereof plus
    accrued and unpaid interest, if any, to the date of purchase;

        (2) the repurchase date, which shall be no earlier than 30 days nor
    later than 60 days from the date such notice is mailed; and

        (3) the procedures determined by Atrium, consistent with the indenture,
    that a holder must follow in order to have its exchange notes purchased. The
    Change of Control Offer needs not to be mailed if Atrium has mailed a
    redemption notice with respect to all the outstanding exchange notes in
    connection with such Change of Control,

    Atrium will comply to the extent with the applicable requirements of Section
14(e) of the Exchange Act and any other securities laws or regulations in
connection with the repurchase of exchange notes pursuant to this covenant.

    The definition of "Change of Control" includes, among other transactions, a
disposition of all or substantially all of the property and assets of Atrium and
its Subsidiaries. In certain circumstances there may be a degree of uncertainty
in ascertaining whether a particular transaction would involve a disposition of
"all or substantially all" of the property or assets of a Person, and it may be
unclear as to whether a Change of Control has occurred and whether Atrium is
required to make an offer to repurchase the exchange notes.

    The occurrence of certain of the events that would constitute a Change of
Control would constitute a default under the credit facility. Future Senior
Indebtedness of Atrium and its Subsidiaries may also contain prohibitions of
certain events that would constitute a Change of Control or require such Senior
Indebtedness to be repurchased upon a Change of Control. Moreover, the exercise
by the holders of their right to require Atrium to repurchase the exchange notes
could cause a default under such Senior Indebtedness. Furthermore, Atrium's
ability to pay cash to the holders upon a repurchase may be limited by Atrium's
then existing financial resources. Finally, if Atrium is not able to prepay the
Indebtedness under the Credit Facility and any other Senior Indebtedness
containing similar restrictions or obtain requisite consents Atrium will be
unable to fulfill its repurchase obligations if holders of exchange notes
exercise their repurchase rights following a Change of Control, thereby
resulting in a default under the indenture.

                                       87

CERTAIN COVENANTS

    The indenture contains, among others, the following covenants:

    LIMITATION ON INDEBTEDNESS.  Atrium will not, and will not permit any of the
Restricted Subsidiaries to incur any Indebtedness or issue Disqualified Stock
and will not permit any of the Restricted Subsidiaries to issue Preferred Stock
to a Person other than Atrium or a Wholly-Owned Subsidiary; PROVIDED, HOWEVER,
that Atrium and a Guarantor may Incur Indebtedness and Atrium may issue
Disqualified Stock after giving PRO FORMA effect thereto and the use of the
proceeds thereof, the Consolidated Coverage Ratio is at least equal to (1)
2.00:1.00 on or prior to May 1, 2001 and (2) 2.25:1.00 after May 1, 2001.

    Notwithstanding the foregoing, each and all of the following shall be
permitted:

        (1) Indebtedness Incurred by Atrium or any Guarantor pursuant to the
    credit facility, so long as the aggregate principal amount of all
    Indebtedness Incurred does not exceed $175.0 million at any time
    outstanding, less the aggregate principal amount required to be repaid with
    the net proceeds of Asset Dispositions;

        (2) Indebtedness in the amount of up to $10.0 million Incurred by Atrium
    or any Guarantor represented by Capitalized Lease Obligations, mortgage
    financing or purchase money obligations, in each case Incurred

       -for the purpose of financing all or any part of the purchase price or
        cost of construction or improvement of property used in a Related
        Business or Incurred to refinance any such purchase price or cost of
        construction or improvement,

       -no later than 365 days after the date of such acquisition or the date of
        completion of such construction or improvement;

        (3) Permitted Indebtedness;

        (4) Indebtedness Incurred by Atrium or any Guarantor in a principal
    amount outstanding which, when taken together with the principal amount of
    all other Indebtedness Incurred pursuant to this clause (4) and then
    outstanding, will not exceed $20.0 million.

    Atrium will not permit any Unrestricted Subsidiary to Incur any Indebtedness
other than Non-Recourse Debt.

    For purposes of determining compliance with this covenant, in the event that
an item of Indebtedness meets the criteria of more than one of the types of
Indebtedness permitted by this covenant, Atrium in its sole discretion shall

permit any of the Restricted Subsidiaries to, directly or indirectly, enter into

benefit of any Affiliate of Atrium or of a Restricted Subsidiary (an "Affiliate
Transaction") unless

        (a) the terms of such Affiliate Transaction are no less favorable to

    arm's-length dealings with a Person who is not such an Affiliate,

    in excess of $2.5 million, the terms of such transaction have been approved

    financial point of view.

    The requirements of this covenant shall not apply to

        (1) any Restricted Payment or other payment or Investment permitted to
    be made pursuant to the covenant described under "--Limitation on Restricted
    Payments,"

        (2) any issuance of securities, or other payments, awards or grants in

                                       91
<PAGE>
        (4) any transaction between or among Atrium and any Restricted
    Subsidiary or between Restricted Subsidiaries, so long as no Person, other
    than a Restricted Subsidiary, that is an Affiliate of Atrium has any direct
    or indirect interest in such Restricted Subsidiary.

    indemnities to, directors, officers and employees of Atrium and its
    Restricted Subsidiaries, in each case in the ordinary course of business,

        (6) transactions pursuant to agreements as in existence on the Issue
    Date,

        (9) amounts paid by Atrium to Ardshiel on the Issue Date in connection
    with the Atrium transactions and

       (10) any obligations of Atrium in respect of management fees payable to
    Ardshiel pursuant to agreements as in effect on the Issue Date.

    LIMITATION ON CAPITAL STOCK OF RESTRICTED SUBSIDIARIES.  Atrium will not
permit any of the Restricted Subsidiaries to issue any Capital Stock to any
Person, or permit any Person, except for Atrium to own any Capital Stock of a
Restricted Subsidiary of Atrium except for Atrium or a Wholly-Owned Subsidiary
of Atrium, if in either case as a result thereof such Restricted Subsidiary
would no longer be a Restricted Subsidiary of Atrium. This provision does not
prohibit (1) Atrium or any of the Restricted Subsidiaries from selling,
transferring or otherwise disposing of all of the Capital Stock of any
Restricted Subsidiary or (2) the designation of a Restricted Subsidiary as an
Unrestricted Subsidiary in compliance with the indenture.

    LIMITATION ON LIENS.  Atrium will not, and will not cause or permit the
Restricted Subsidiaries to, directly or indirectly, Incur any Liens of any kind
securing any Senior Subordinated Indebtedness or Subordinated Obligations
against any of their respective properties or assets now owned or hereafter
acquired, or any proceeds income or profits therefrom, unless the exchange notes
are, or in the case of a Restricted Subsidiary that is a Guarantor, the
Guarantee of such Guarantor is, equally and ratably secured with such Senior
Subordinated Indebtedness or, in the case of Subordinated Obligations, prior to
such Subordinated Obligations, with a Lien on the same properties and assets
securing such Senior Subordinated Indebtedness or Subordinated Obligations, for
so long as such Senior Subordinated Indebtedness or Subordinated Obligations are
secured by such Lien, except for Permitted Liens.

    LIMITATION ON SALE OF ASSETS.  Atrium will not, and will not cause or permit
any of the Restricted Subsidiaries to, directly or indirectly, make any Asset
Disposition, unless (1) Atrium or such Restricted Subsidiary, receives
consideration at the time of such Asset Disposition at least equal to the fair
market value, as determined in good faith by Atrium's board of directors, of the
assets sold or otherwise disposed of and (2) at least 75% of such consideration
consists of cash or Cash Equivalents.

    Atrium or Restricted Subsidiary may apply the Net Available Cash of any
Asset Disposition to acquire Additional Assets within 360 days after the receipt
thereof,

       -if the Net Available Cash is not required to be applied to repay
        permanently any Senior Indebtedness outstanding as required by the terms
        thereof,

       -or Atrium determines not to apply such Net Available Cash to the
        permanent repayment of the Senior Indebtedness,

       -or if no Senior Indebtedness is outstanding,

                                       92
<PAGE>
    If the Net Available Cash of any Asset Disposition is not applied within 360
days of the applicable Asset Disposition (such Net Available Cash, the
"Unutilized Net Available Cash"), Atrium will, within 20 days after the date
that is 360 days from the receipt of such Net Available Cash, make an offer to
purchase (the "Net Available Cash Offer") all outstanding exchange notes up to a
maximum principal amount of exchange notes equal to the exchange notes Portion
of Unutilized Net Available Cash, at a purchase price in cash equal to 100%
thereof, plus accrued and unpaid interest thereon, if any, to the purchase date.
The Net Available Cash Offer may be deferred until there is aggregate Unutilized
Net Available Cash equal to or in excess of $10.0 million, at which time the
entire amount of such Unutilized Net Available Cash, shall be applied.

    Atrium may apply the Unutilized Net Available Cash otherwise required to be
applied to a Net Available Cash Offer to offer to purchase

       -and any other Indebtedness of Atrium which ranks equally with the
        exchange notes (the "Other Indebtedness") requiring that an offer to
        repurchase such Indebtedness be made upon the consummation of any Asset
        Disposition,

       -to a Net Available Cash Offer,

so long as the amount of such Unutilized Net Available Cash applied to
repurchase the exchange notes is not less than the exchange notes Portion of
Unutilized Net Available Cash. Atrium shall make the Net Available Cash Offer in
respect to any Unutilized Net Available Cash, at the same time as the analogous
offer to purchase is made under any Other Indebtedness and the purchase date
shall be the same under the Net Available Cash Offer as the purchase date
pursuant to any Other Indebtedness.

    For purposes of this covenant, "Exchange Notes Portion of Unutilized Net
Available Cash" in respect of a Net Available Cash Offer means (a) if no Other
Indebtedness is concurrently being offered to be purchased, the amount of the
Unutilized Net Available Cash in respect of such Net Available Cash Offer and
(b) if Other Indebtedness is concurrently being offered to be purchased, an
amount equal to the product of (x) the Unutilized Net Available Cash in respect
of such Net Available Cash Offer and (y) a fraction the numerator of which is
the principal amount of all exchange notes tendered pursuant to the Net
Available Cash Offer related to such Unutilized Net Available Cash (the
"Exchange Notes Amount") and the denominator of which is the sum of the Exchange
Notes Amount and the lesser of the aggregate principal face amount or accreted
value as of the relevant purchase date of all Other Indebtedness tendered
pursuant to a concurrent offer to purchase such Other Indebtedness made at the
time of such Net Available Cash Offer.

    With respect to any Net Available Cash Offer effected pursuant to this
covenant, to the extent that the principal amount of the exchange notes tendered
pursuant to such Net Available Cash Offer exceeds the Exchange Notes Portion of
Unutilized Net Available Cash with respect thereto, the exchange notes shall be
purchased PRO RATA based on the principal amount of the exchange notes tendered
by each Holder. Holders whose exchange notes are purchased only in part will be
issued new exchange notes equal in principal amount to the unpurchased portion
of the exchange notes surrendered.

    To the extent the Exchange Notes Portion of Unutilized Net Available Cash
available for any Net Available Cash Offer effected pursuant to this covenant
exceeds the aggregate purchase price for the exchange notes validly tendered and
purchased by Atrium pursuant thereto, such excess shall no longer be deemed
Unutilized Net Available Cash and shall be available to Atrium and its
Restricted Subsidiaries for any purpose not prohibited under the indenture.

    For the purposes of this covenant, the following will be deemed to be cash,
but not Net Available Cash: (x) the assumption by the transferee of
Indebtedness, other than Subordinated Obligations, of Atrium or any Guarantor
and the release of Atrium or such Guarantor from all liability on such
Indebtedness in connection with such Asset Disposition, in which case Atrium
shall, without further action, be deemed to have applied such assumed
Indebtedness in accordance with the second paragraph under

                                       93
<PAGE>
this covenant, and (y) securities received by Atrium or any Restricted
Subsidiary of Atrium from the transferee that are promptly converted, but in no
event later than 30 days after the relevant Asset Disposition, by Atrium or such
Restricted Subsidiary into cash.

    Atrium will comply, to the extent applicable, with the requirements of
Section 14(e) of the Exchange Act and any other applicable securities laws or
regulations in connection with the repurchase of exchange notes pursuant to a
Net Available Cash Offer, and any violation of the provisions of the Indenture
relating to such Net Available Cash Offer occurring as a result of such
compliance shall not be deemed a Default.

    LIMITATION ON DIVIDENDS AND OTHER PAYMENT RESTRICTIONS AFFECTING RESTRICTED
SUBSIDIARIES. The indenture will provide that Atrium will not, and will not
cause or permit any of the Restricted Subsidiaries to, directly or indirectly,
create or permit to exist or become effective any consensual encumbrance or
restriction on the ability of any Restricted Subsidiary to (1) pay dividends or
make any other distributions on its Capital Stock to Atrium or any other
Restricted Subsidiary or pay any Indebtedness or other obligation owed to Atrium
or any other Restricted Subsidiary, (2) make any loans or advances to Atrium or
to any other Restricted Subsidiary which directly or indirectly owns the Capital
Stock of such Restricted Subsidiary or (3) transfer any of its property or
assets to Atrium or to any other Restricted Subsidiary which directly or
indirectly owns the Capital Stock of such Restricted Subsidiary, except for:

        (a) any encumbrance or restriction pursuant to an agreement in effect at
    or entered into on the Issue Date, including, without limitation, the Credit
    Facility and the indenture;

        (b) any encumbrance or restriction with respect to such a Restricted
    Subsidiary pursuant to an agreement relating to any Indebtedness issued by
    such Restricted Subsidiary on or prior to the date on which such Restricted
    Subsidiary was acquired by Atrium and outstanding on such date, other than
    Indebtedness issued as consideration in, or to provide all or any portion of
    the funds or credit support utilized to consummate, the transaction or
    series of related transactions pursuant to which such Restricted Subsidiary
    became a Restricted Subsidiary of Atrium or was acquired by Atrium;

        (c) any encumbrance or restriction with respect to such a Restricted
    Subsidiary (A) pursuant to an agreement evidencing Indebtedness Incurred
    without violation of the Indenture or (B) effecting a refinancing of
    Indebtedness issued pursuant to an agreement referred to in clause (a) or
    (b) above or this clause (c) or contained in any amendment to an agreement
    referred to in clause (a) or (b) above or this clause (c); PROVIDED,
    HOWEVER, that the encumbrances and restrictions with respect to such
    Restricted Subsidiary contained in any of such agreement, refinancing
    agreement or amendment, taken as a whole, are no less favorable to the
    holders of the exchange notes in any material respect, as determined in good
    faith by the board of directors of Atrium, than encumbrances and
    restrictions with respect to such Restricted Subsidiary contained in, in the
    case of (A) above, the Credit Facility, and in the case of (B) above, the
    agreement being refinanced or amended;

        (d) in the case of clause (iii) above, any encumbrance or restriction
    (A) that restricts in a customary manner the subletting, assignment or
    transfer of any property or asset that is a lease, license, conveyance or
    contract or similar property or asset, (B) by virtue of any transfer of,
    agreement to transfer, option or right with respect to, or Lien on, any
    property or assets of Atrium or any Restricted Subsidiary not otherwise
    prohibited by the Indenture, (C) that is included in a licensing agreement
    to the extent such restrictions limit the transfer of the property subject
    to such licensing agreement or (D) arising or agreed to in the ordinary
    course of business and that does not, individually or in the aggregate,
    detract from the value of property or assets of Atrium or any of its
    Subsidiaries in any manner material to Atrium or any such Restricted
    Subsidiary;

        (e) in the case of clause (iii) above, restrictions contained in
    security agreements, mortgages or similar documents securing Indebtedness of
    a Restricted Subsidiary to the extent such restrictions restrict the
    transfer of the property subject to such security agreements; PROVIDED, that
    such Indebtedness and such Lien is permitted by the Indenture;

                                       94
<PAGE>
        (f) any restriction with respect to such a Restricted Subsidiary imposed
    pursuant to an agreement entered into for the sale or disposition of all or
    substantially all the Capital Stock or assets of such Restricted Subsidiary
    pending the closing of such sale or disposition; and

        (g) encumbrances or restrictions arising or existing by reason of
    applicable law.

    LIMITATIONS ON GUARANTEES BY RESTRICTED SUBSIDIARIES.  Atrium will permit
any of the Restricted Subsidiaries, directly or indirectly, to guarantee the
payment of any Indebtedness of Atrium ("Other Guaranteed Indebtedness") unless
such Restricted Subsidiary

    (A) is a Guarantor, or

    (B) simultaneously executes and delivers a supplemental indenture pursuant
to which it will become a Guarantor.

    However, if such Other Guaranteed Indebtedness is (A) Senior Subordinated
Indebtedness, the Guarantee of such Restricted Subsidiary shall be rank equally
in right of payment with the guarantee of the Other Guaranteed Indebtedness; or
(B) Subordinated Obligations, the Guarantee of such Restricted Subsidiary shall
be senior in right of payment to the guarantee of the Other Guaranteed
Indebtedness, which guarantee of such Subordinated Obligations shall provide
that such guarantee is subordinated to the Guarantee of such Restricted
Subsidiary to the same extent and in the same manner as the Other Guaranteed
Indebtedness is subordinated to the exchange notes.

    Furthermore, each Restricted Subsidiary issuing a Guarantee will be
automatically and unconditionally released and discharged from its obligations
under such Guarantee upon the release or discharge of the guarantee of the Other
Guaranteed Indebtedness that resulted in the creation of such Guarantee, except
a discharge or release by, or as a result of, any payment under the guarantee of
such Other Guaranteed Indebtedness by such Restricted Subsidiary. In addition,
Atrium may, at any time, cause a Restricted Subsidiary to become a Guarantor by
executing and delivering a supplemental indenture providing for the guarantee of
payments of the exchange notes by such Restricted Subsidiary on the basis
provided in the Indenture.

    PROVISION OF FINANCIAL STATEMENTS.  For so long as the exchange notes are
outstanding, Atrium will, to the extent permitted by SEC practice and applicable
law and regulations, file with the SEC the annual reports, quarterly reports and
other documents which Atrium would have been required to file with the SEC
pursuant to such Section 13(a) or 15(d), if Atrium was so subject, such
documents to be filed with the SEC on or prior to the date (the "Required Filing
Dates") by which Atrium would have been required so to file such documents if
Atrium was so subject.

    Atrium will also in any event within 15 days of each Required Filing Date,
whether or not permitted or required to be filed with the SEC, (1) transmit or
cause to be transmitted by mail to all holders of exchange notes, as their names
and addresses appear in the security register, without cost to such holders and
(2) file with the Trustee, copies of the annual reports, quarterly reports and
other documents which Atrium would have been required to file with the SEC
pursuant to Section 13(a) or 15(d) of the Exchange Act, or any successor
provision thereto, if Atrium were subject to either of such Sections.

    In addition, for so long as any exchange notes remain outstanding, Atrium
will furnish

    - to the holders of exchange notes and prospective investors, at their
      request, the information required to be delivered pursuant to Rule
      144(d)(4) under the Securities Act, and,

    - to any beneficial holder of exchange notes known to Atrium, information of
      the type that would be filed with the SEC pursuant to the provisions
      described above if not obtainable from the SEC.

    CONSOLIDATION, MERGER, SALE OF ASSETS, ETC.  Atrium will not

    - consolidate with or merge with or into, or

                                       95
<PAGE>
    - sell, convey, transfer or lease all or substantially all its assets to,
      any Person,

    - or permit any of its Restricted Subsidiaries to enter into any such
      transaction if such transaction would result in the sale, conveyance,
      transfer or lease of all or substantially all of the assets of Atrium and
      the Restricted Subsidiaries on a consolidated basis, unless:

        (1) the Surviving Person shall be a corporation organized and existing
    under the laws of the United States of America, any State thereof or the
    District of Columbia and the Surviving Person shall expressly assume by a
    supplemental indenture executed and delivered to the trustee, in form
    satisfactory to the trustee, all the obligations of Atrium under the
    exchange notes and the indenture and the registration rights agreement;

        (2) immediately after giving effect to such transaction, no Default or
    Event of Default shall have occurred and be continuing; and

        (3) immediately after giving effect to such transaction, the Surviving
    Person would be able to Incur an additional $1.00 of Indebtedness pursuant
    to the first paragraph under the covenant described under "--Certain
    Covenants--Limitation on Indebtedness."

Notwithstanding clauses (2) and (3) above:

       (1) any Restricted Subsidiary of Atrium may consolidate with, merge into
           or transfer all or part of its properties and assets to Atrium or any
           Wholly Owned Subsidiary that is a Guarantor; and

       (2) Atrium may merge with an Affiliate incorporated solely for the
           purpose of reincorporating Atrium in another jurisdiction to realize
           tax or other benefits.

    No Guarantor will in any transaction or series of related transactions,
consolidate with or merge with or into another Person, whether or not such
Person is affiliated with such Guarantor and whether or not such Guarantor is
the Surviving Person, unless

        (1) the Surviving Person shall be a corporation organized and existing
    under the laws of the United States of America, any State thereof or the
    District of Columbia;

        (2) the Surviving Person expressly assumes by a supplemental indenture
    all the obligations of such Guarantor under its Guarantee and the
    performance and observance of every covenant of the indenture and the
    registration rights agreement to be performed or observed by such Guarantor;
    and

        (3) immediately after giving effect to such transaction, no Default or
    Event of Default shall have occurred and be continuing.

    After any consolidation or merger of Atrium or any Guarantor or any transfer
of all or substantially all of the assets of Atrium in which Atrium or a
Guarantor is not the Surviving Person, the Surviving Person shall succeed to,
every right and power of Atrium under the indenture, the exchange notes and the
registration rights agreement or such Guarantor under the indenture, the
Guarantee of such Guarantor and the registration rights agreement as the case
may be, with the same effect as if such successor corporation had been named as
Atrium or such, except in the case of

       (a) a lease, or

       (b) any sale, assignment, conveyance, transfer or other disposition to a
           Restricted Subsidiary of Atrium or such Guarantor,

    Atrium shall be discharged from all obligations and covenants under the

Guarantor shall be discharged from all obligations and covenants under the
indenture, the registration rights agreement and the Guarantee of such
Guarantor.

    For all purposes of the indenture and the exchange notes, Subsidiaries of
any Surviving Person shall upon such transaction or series of related
transactions become Restricted Subsidiaries unless designated as Unrestricted
Subsidiaries pursuant to and in accordance with the terms of the indenture. All
Indebtedness and all Liens on property or assets of Atrium and the Restricted
Subsidiaries in existence immediately prior to such transaction or series of
related transactions will be deemed to have been incurred upon such transaction
or series of related transactions.

EVENTS OF DEFAULT

    The following will be "Events of Default" under the indenture:

        (1) default in any payment of interest on any note when the same becomes
    due and payable, and such default continues for a period of 30 days; or

        (2) default in the payment of the principal of any note when the same

    of Assets, Etc."; or

        (4) Atrium or any Guarantor fails to comply with any of its obligations
    described under the option "Change of Control" and "Certain Covenants" and
    such failure continues for 30 days after written notice of such failure
    requiring Atrium to remedy the failure shall have been given

       (x) to Atrium by the trustee, or

       (y) to Atrium and the trustee by the holders of at least 25% in aggregate
           principal amount of the exchange notes then outstanding; or

        (5) Atrium or any Guarantor fails to comply with any of its obligations
    in the exchange notes, the Guarantees or the indenture and such failure
    continues for 60 days after written notice of such failure requiring Atrium
    to remedy the failure shall have been given

    (x) to Atrium by the trustee or

    (y) to Atrium and the trustee by the holders of at least 25% in aggregate
principal amount of the exchange notes then outstanding; or

        (6) Indebtedness of Atrium or any Restricted Subsidiary is not paid
    within any applicable grace period after final maturity or is accelerated by
    its holders because of a default and the total amount of such Indebtedness
    in the aggregate exceeds $10.0 million at the time and such default have not
    been cured or acceleration rescinded within a 30 day period; or

        (7) one or more judgments or decrees for the payment of money in excess
    of $10.0 million in the aggregate is entered against Atrium or any
    Significant Subsidiary and such judgment or decree remains undischarged or
    unstayed for a period of 60 days after it becomes final and non-appealable;
    or

        (8) (a) any Guarantee of a Significant Subsidiary ceases to be in full
    force and effect or is declared null and void or (b) any Guarantor that is a
    Significant Subsidiary denies that it has any further liability under any
    Guarantee, or gives notice to such effect; or

        (9) certain events of bankruptcy, insolvency or reorganization with
    respect to Atrium or any Significant Subsidiary shall have occurred.

    If an Event of Default, other than as specified in clause (g) with respect
to Atrium, occurs and is continuing, the trustee or the holders of at least 25%
in principal amount of the outstanding exchange notes by notice to Atrium may
declare the principal of and accrued and unpaid interest, if any, on all the
exchange notes to be due and payable.

                                       97
<PAGE>
    Upon such a declaration, such principal and accrued and unpaid interest
shall be due and payable immediately. However, so long as the Credit Facility
shall be in force and effect, if an Event of Default have occurred and is
continuing, any such acceleration shall not be effective until the earlier to
occur of

       (x) five business days following delivery of a notice of such
           acceleration to the Representative under the Credit Facility and

       (y) the acceleration of any Indebtedness under the Credit Facility.

    If an Event of Default under clause (g) relating to certain events of
bankruptcy, insolvency or reorganization of Atrium occurs, the principal of and
accrued and unpaid interest on all the exchange notes will become and be
immediately due and payable without any declaration or other act on the part of
the trustee or any holders. Under certain circumstances, the holders of a
majority in principal amount of the outstanding exchange notes may rescind any
such acceleration with respect to the exchange notes and its consequences.

    If an Event of Default occurs and is continuing, the Trustee will be under
no obligation to exercise any of the rights or powers under the indenture at the
request or direction of any of the holders unless such holders have offered to
the trustee reasonable indemnity or security against any loss, liability or
expense. Except to enforce the right to receive payment of principal, premium,
if any, or interest when due, no holder may pursue any remedy with respect to
the indenture or the exchange notes unless

           (1) such holder has previously given the trustee notice that an Event
               of Default is continuing,

           (2) holders of at least 25% in principal amount of the outstanding
               exchange notes have requested the trustee to pursue the remedy,

           (3) such holders have offered the trustee reasonable security or
               indemnity against any loss, liability or expense,

           (4) the trustee has not complied with such request within 60 days
               after the receipt of the request and the offer of security or
               indemnity and

           (5) the holders of a majority in principal amount of the outstanding
               exchange notes have not given the trustee a direction that, in
               the opinion of the trustee, is inconsistent with such request
               within such 60-day period.

    The holders of a majority in principal amount of the outstanding exchange
notes are given the right to direct the time, method and place of conducting any
proceeding for any remedy available to the trustee or of exercising any trust or
power conferred on the trustee. The trustee, however, may refuse to follow any
direction that conflicts with law or the indenture or that the trustee
determines is unduly prejudicial to the rights of any other holder or that would
involve the trustee in personal liability. Prior to taking any action under the
Indenture, the trustee shall be entitled to indemnification satisfactory to it
in its sole discretion against all losses and expenses caused by taking or not
taking such action.

    If a Default occurs and is continuing and is known to the Trustee, the
Trustee must mail to each holder notice of the Default within 90 days after it
occurs. Except in the case of a Default in the payment of principal of, premium,
if any, or interest on any note, the trustee may withhold notice if and so long
as its board of directors, a committee of its board of directors or a committee
of its trust officers in good faith determines that withholding notice is in the
interests of the holders of exchange notes. In addition, Atrium is required to
deliver to the trustee, written notice of any events which would constitute
certain Defaults within 30 days after the occurrence of such events.

                                       98
<PAGE>
AMENDMENTS AND WAIVERS

    The Indenture may be amended with the consent of the holders of a majority
in principal amount of the exchange notes then outstanding and any past default
or compliance with any provisions may be waived with the consent of the holders
of a majority in principal amount of the exchange notes then outstanding.
However, without the consent of each holder of an outstanding note affected, no
amendment may, among other things:

        (1) reduce the amount of exchange notes whose holders must consent to an
    amendment;

        (2) reduce the stated rate of or extend the stated time for payment of
    interest on any note;

        (3) reduce the principal of or change the stated maturity of any note;

        (4) reduce the premium payable upon the redemption or repurchase of any
    note or change the time at which any note may be redeemed;

        (5) make any note payable in money other than that stated in the note;

        (6) impair the right of any holder to receive payment of principal of
    and interest on such holder's exchange notes on or after the due dates
    therefor or to institute suit for the enforcement of any payment on or with
    respect to such holder's exchange notes;

        (7) modify the ranking or priority of any note or the Guarantee of any
    Guarantor in any adverse manner;

        (8) following the occurrence of a Change of Control or an Asset
    Disposition, modify in a manner materially adverse to the holders of
    exchange notes affected thereby the provisions of any covenant in the
    indenture requiring Atrium to make and consummate an offer to purchase with
    respect to such Change of Control or a Net Available Cash Offer with respect
    to such Asset Disposition;

        (9) release any Guarantor that is a Significant Subsidiary from any of
    its obligations under its Guarantee or the Indenture otherwise than in
    accordance with the indenture; or

       (10) make any change in the amendment or waiver provisions which require
    each affected holder's consent.

    Without the consent of any holder, Atrium, the Guarantors and the Trustee
may amend the Indenture to cure any ambiguity, omission, defect or
inconsistency, to provide for the assumption by a successor corporation of the
obligations of Atrium under the Indenture, to add further Guarantees with
respect to the exchange notes, to secure the exchange notes, to add to the
covenants of Atrium for the benefit of the holders, to make any change that does
not adversely affect the rights of any holder or to comply with any requirement
of the SEC in connection with the qualification of the Indenture under the Trust
Indenture Act. However, any amendment made to the subordination provisions of
the Indenture that adversely affects the rights of any holder of Senior
Indebtedness then outstanding shall not be effective as to the holders of such
outstanding Senior Indebtedness unless the holders of such Senior Indebtedness
(or any group or representative thereof authorized to give a consent) consent to
such change.

    The consent of the holders is not necessary under the Indenture to approve
the particular form of any proposed amendment. It is sufficient if such consent
approves the substance of the proposed amendment.

    After an amendment under the Indenture becomes effective, Atrium is required
to mail to the holders a notice briefly describing such amendment. However, the
failure to give such notice to all the holders or any defect therein will not
impair or affect the validity of the amendment.

                                       99
<PAGE>
DEFEASANCE

    Atrium at any time may terminate all its and the Guarantors' obligations
under the exchange notes and the Indenture ("legal defeasance"), except for
certain obligations, including those respecting the defeasance trust and
obligations to register the transfer or exchange of the exchange notes, to
replace mutilated, destroyed, lost or stolen exchange notes and to maintain a
registrar and paying agent in respect of the exchange notes. Atrium at any time
may terminate its and the Guarantors' obligations under covenants described
under "Certain Covenants" (other than clause (i) of the first and second
paragraphs under "Certain Covenants--Consolidation, Merger, Sale of Assets,
etc."), the operation of the cross acceleration provision, the bankruptcy
provisions with respect to Significant Subsidiaries, the judgment default
provision and the Guarantee provision described under "Events of Default"
("covenant defeasance").

    Atrium may exercise its legal defeasance option notwithstanding its prior
exercise of its covenant defeasance option. If Atrium exercises its legal
defeasance option, payment of the exchange notes may not be accelerated because
of an Event of Default with respect thereto. If Atrium exercises its covenant
defeasance option, payment of the exchange notes may not be accelerated because
of an Event of Default specified in clause (iv), (vi), (vii), (viii) or (ix)
(with respect only to Significant Subsidiaries) under "Events of Default" above
or because of the failure of Atrium to comply with clause (ii) or (iii) in the
first paragraph and clause (iii) in the second paragraph under "Certain
Covenants--Consolidation, Merger, Sale of Assets, etc." above.

    In order to exercise either defeasance option, Atrium must irrevocably
deposit in trust (the "defeasance trust") with the Trustee money or U.S.
Government Obligations for the payment of principal, premium (if any) and
interest on the exchange notes to redemption or maturity, as the case may be,
and must comply with certain other conditions, including delivery to the Trustee
of an Opinion of Counsel to the effect that holders of the exchange notes will
not recognize income, gain or loss for Federal income tax purposes as a result
of such deposit and defeasance and will be subject to Federal income tax on the
same amount and in the same manner and at the same times as would have been the
case if such deposit and defeasance had not occurred (and, in the case of legal
defeasance only, such Opinion of Counsel must be based on a ruling of the
Internal Revenue Service or other change in applicable Federal income tax law).

CONCERNING THE TRUSTEE

    State Street Bank and Trust Company is to be the Trustee under the Indenture
and has been appointed by Atrium as Registrar and Paying Agent with regard to
the exchange notes.

    The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of Atrium, to obtain payment of claims in certain
cases, or to realize on certain property received in respect of any such claim
as security or otherwise. The Trustee will be permitted to engage in other
transactions; however, if it acquires any conflicting interest (as defined) it
must eliminate such conflict or resign.

    The holders of a majority in aggregate principal amount of the then
outstanding exchange notes issued under the Indenture will have the right to
direct the time, method and place of conducting any proceeding for exercising
any remedy available to the Trustee. The Indenture provides that in case an
Event of Default shall occur (which shall not be cured) the Trustee will be
required, in the exercise of its power, to use the degree of care of a prudent
man in the conduct of his own affairs. Subject to such provisions, the Trustee
will be under no obligation to exercise any of its rights or powers under the
Indenture at the request of any of the holders of the exchange notes issued
thereunder, unless they shall have offered to the Trustee security and indemnity
satisfactory to it.

                                      100
<PAGE>
GOVERNING LAW

    The Indenture provides that it, the exchange notes and the Guarantees will
be governed by, and construed in accordance with, the laws of the State of New
York without giving effect to applicable principles of conflict of laws to the
extent that the application of the law of another jurisdiction would be required
thereby.

period shall be

    (a) reduced by an amount equal to the Consolidated Interest Expense
attributable to any Indebtedness of Atrium or any of the Restricted Subsidiaries
repaid, repurchased, defeased or otherwise discharged with respect to Atrium and
its continuing Restricted Subsidiaries in connection with such Asset Disposition
for such period or, if the Capital Stock of any Restricted Subsidiary of Atrium
is sold, transferred or otherwise disposed of, the Consolidated Interest Expense

Subsidiary to the extent Atrium and the continuing Restricted Subsidiaries are
no longer liable for such Indebtedness after such sale, transfer or other
disposition, and

such Asset Acquisition occurred on the first day of such period, and (5) if
since the beginning of such period any Person that subsequently became a
Restricted Subsidiary of Atrium or was merged with or into Atrium or any
Restricted Subsidiary of Atrium since the beginning of such period shall have
made any Asset Disposition or Asset Acquisition that would have required an
adjustment pursuant to clause (3) or (4) above if made by Atrium or a Restricted
Subsidiary of Atrium during such period, Consolidated Cash Flow and Consolidated

effect thereto as if such Asset Disposition or Asset Acquisition occurred on the

an Asset Acquisition, the amount of income or earnings relating thereto and the
amount of Consolidated Interest Expense associated with any Indebtedness
Incurred in connection therewith, the PRO FORMA calculations shall be determined
in accordance with GAAP and Regulation S-X under the Securities Act, to the
extent applicable, in good faith by a responsible financial or accounting
officer of Atrium. If any Indebtedness bears a floating rate of interest and is
being given PRO FORMA effect, the interest expense on such Indebtedness shall be
calculated as if the rate in effect on the date of determination had been the
applicable rate for the entire period, taking into account any Interest Rate
Agreement applicable to such Indebtedness if such Interest Rate Agreement has a
remaining term that extends at least until the end of such period.

                         BOOK-ENTRY; DELIVERY AND FORM

    The exchange notes will be represented by one or more, permanent global
notes in definitive, fully registered book-entry form of the global securities,
which will be registered in the name of a nominee of The Depositary Trust
Company and deposited on behalf of purchasers of the exchange notes represented
thereby with a custodian for DTC for credit to the respective accounts of the
purchasers, or to such other accounts as they may direct, at DTC.

    THE GLOBAL SECURITIES.  Atrium expects that pursuant to procedures
established by DTC

    (a) upon deposit of the Global Securities, DTC or its custodian will credit
on its internal system portions of the Global Securities which shall be
comprised of the corresponding respective amount of the Global Securities to the
respective accounts of persons who have accounts with such depositary; and

    (b) ownership of the exchange notes will be shown on, and the transfer of
ownership thereof will be effected only through, records maintained by DTC or
its nominee, with respect to interests of participants, as defined below, and
the records of participants, with respect to interests of persons other than
Participants.

    Such accounts initially will be designated by or on behalf of the initial
purchaser and ownership of beneficial interests in the global securities will be
limited to persons who have accounts with DTC or participants or persons who
hold interests through participants. Noteholders may hold their interests in a
global security directly through DTC if they are participants in such system, or
indirectly through organizations which are participants in such system.

    So long as DTC or its nominee is the registered owner or holder of any of
the exchange notes, DTC or such nominee will be considered the sole owner or
holder of such exchange notes represented by such global securities for all
purposes under the indenture and under the exchange notes represented thereby.
No beneficial owner of an interest in the global securities will be able to
transfer such interest except in accordance with the applicable procedures of
DTC in addition to those provided for under the indenture.

                                      118
<PAGE>
    Payments of the principal, premium, interest and other amounts on the
exchange notes represented by the global securities will be made to DTC or its
nominee as the registered owner thereof. None of Atrium, the trustee or any
paying agent under the indenture will have any responsibility or liability for
any aspect of the records relating to or payments made on account of beneficial
ownership interests in the global securities or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interest.

    Atrium expects that DTC or its nominee, upon receipt of any payment of the
principal, premium, interest or other amounts on the exchange notes represented
by the global securities, will credit participants' accounts with payments in
amounts proportionate to their respective beneficial interests in the global
securities as shown on the records of DTC or its nominee. Atrium also expects
that payments by participants to owners of beneficial interests in the global
securities held through such Participants will be governed by standing
instructions and customary practice as is now the case with securities held for
the accounts of customers registered in the names of nominees for such
customers. Such payment will be the responsibility of such participants.
Transfers between participants in DTC will be effected in accordance with DTC
rules and will be settled in immediately available funds.

    DTC has advised Atrium that DTC will take any action permitted to be taken
by a holder of exchange notes, including the presentation of exchange notes for
exchange as described below, only at the direction of one or more participants
to whose account the DTC interests in the Global Securities are credited and
only in respect of the aggregate principal amount of as to which such
Participant or participants has or have given such direction.

    DTC has advised Atrium as follows:

    - DTC is a limited purpose trust company organized under the laws of the
      State of New York, a member of the Federal Reserve System, a "clearing
      corporation" within the meaning of the Uniform Commercial Code and a
      clearing agency registered pursuant to the provisions of Section 17A of
      the Exchange Act.

    - DTC was created to hold securities for its Participants and facilitate the
      clearance and settlement of securities transactions between Participants
      through electronic book-entry changes in accounts of its Participants,
      thereby eliminating the need for physical movement of certificates.

    Participants include securities brokers and dealers, banks, trust companies
and clearing corporations and certain other organizations. Indirect access to
the DTC system is available to others such as banks, brokers, dealers and trust
companies or indirect participants that clear through or maintain a custodial
relationship with a participant, either directly or indirectly.

    Although DTC is expected to follow the foregoing procedures in order to
facilitate transfers of interests in the global securities among participants of
DTC, DTC is under no obligation to perform such procedures, and such procedures
may be discontinued at any time. None of Atrium, the trustee or the paying agent
will have any responsibility for the performance by DTC or its direct or
indirect participants of their respective obligations under the rules and
procedures governing their operations.

    CERTIFICATED SECURITIES.  Interests in the global securities will be
exchanged for physical delivery of certificates or Certificated Securities only
if

    (1) DTC is at any time unwilling or unable to continue as depositary for the
Global Securities, or DTC ceases to be a clearing agency registered under the
Exchange Act, and a successor depositary is not appointed by Atrium within 90
days, or

    (2) an event of default under the Indenture has occurred and is continuing
with respect to the exchange notes.

United States Treasury securities with a constant maturity, as compiled and
published in the most recent Federal Reserve Statistical Release H.15 (519)
which has become publicly available at least two business days prior to the
applicable redemption date (or, if such Statistical Release is no longer
published, any publicly available source of similar market data), most nearly
equal to the period from such redemption date to May 1, 2004; PROVIDED, HOWEVER,
that if the period from such redemption date to May 1, 2004 is not equal to the
constant maturity of a United States Treasury security for which a weekly
average yield is given, the Treasury Rate shall be obtained by linear
interpolation (calculated to the nearest one-twelfth of a year) from the weekly
average yields of United States Treasury securities for which such yields are
given, except that if the period from such redemption date to May 1, 2004 is
less than one year, the weekly average yield on actually traded United States
Treasury securities adjusted to a constant maturity of one year shall be used.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

    The following is a general discussion of the material United States federal
income tax consequences of the exchange offer and the acquisition, ownership and
disposition of the notes and exchange notes to U.S. Holders and non-U.S.
Holders, as defined below. This discussion is based on currently existing
provisions of the Internal Revenue Code of 1986, as amended, Treasury
regulations promulgated thereunder, and administrative and judicial
interpretations thereof, all as in effect on the date hereof and all of which
are subject to change, possibly on a retroactive basis.

    This discussion applies only to initial beneficial owners that purchased the
notes upon original issuance at the initial offering price thereof, and is
limited to initial beneficial owners that hold the outstanding notes and
exchange notes as capital assets. Moreover, this discussion does not address all
of the United States federal income tax consequences that may be relevant to
particular beneficial owners in light of their personal circumstances, or to
certain types of beneficial owners. Such beneficial owners may include, for
example, pass-through entities (E.G., partnerships) or persons who hold the
outstanding notes or exchange notes through pass-through entities, banks and
other financial institutions, insurance companies, tax-exempt entities, dealers
in securities, certain former citizens or former long-term residents of the
United States, hybrid entities, persons holding the exchange notes or Exchange
exchange notes as part of a hedging or conversion transaction or a straddle or
U.S. Holders that have a functional currency other than the U.S. dollar.

    This discussion does not address the tax consequences to Non-U.S. Holders
that are subject to U.S. federal income tax on a net basis on income realized
with respect to a note or exchange note because such income is effectively
connected with the conduct of a U.S. trade or business. Such holders are
generally taxed in a similar manner to U.S. Holders; however, certain special
rules apply. In addition, this discussion does not include any description of
the tax laws of any state, local or foreign government that may be applicable to
a particular beneficial owner.

    As used herein, the term "U.S. Holder" means a beneficial owner of a note or
exchange note that is, for U.S. federal income tax purposes,

        (1) a citizen or resident of the United States,

        (2) a corporation (including an entity treated a corporation for United
    States federal income tax purposes) or partnership created or organized in
    or under the laws of the United States or any political subdivision thereof,

        (3) an estate, the income of which is subject to United States federal
    income tax regardless of its source, or

        (4) a trust if a United States court can exercise primary supervision
    over the administration of the trust and one or more United States persons
    have the authority to control all substantial decisions of the trust, or if
    the trust was in existence on August 20, 1996 and has properly elected to
    continue to be treated as a United States person.

    The term "Non-U.S. Holder" means a beneficial owner of a note or exchange
Note that is not a U.S. Holder.

    Prospective purchasers are urged to consult their own tax advisors as to the
particular United States federal income and other tax consequences to them of
the acquisition, ownership and disposition of the notes and exchange notes, as
well as the tax consequences under state, local and foreign tax laws, and the
possible effects of changes in tax laws.

                                      121

UNITED STATES FEDERAL INCOME TAXATION OF U.S. HOLDERS

    PAYMENTS OF INTEREST.

    In general, interest on a note or exchange note will be taxable to a U.S.
Holder as ordinary income at the time it accrues, or is actually or
constructively received, in accordance with the U.S. Holder's method of
accounting for United States federal income tax purposes. The Company
anticipates that the exchange notes will be issued without original issue
discount within the meaning of Section 1273 of the Internal Revenue Code and the
following discussion so assumes.

    SALE, EXCHANGE OR RETIREMENT OF THE EXCHANGE NOTES OR EXCHANGE EXCHANGE
     NOTES.

    Upon the sale, exchange, redemption, retirement at maturity or other taxable
disposition of a note or exchange note, a U.S. Holder generally will recognize
taxable gain or loss equal to the difference between

        (1) the sum of cash plus the fair market value of all other property
    received on such disposition, except to the extent such cash or property is
    attributable to accrued but unpaid interest which will be taxable as
    ordinary income, and

        (2) such U.S. Holder's adjusted tax basis in the note or exchange note.

Gain or loss recognized on the disposition of a note or exchange note generally
will be capital gain or loss. Capital gains of individuals derived in respect of
capital assets held for more than one year are eligible for reduced rates of
taxation. The deductibility of capital losses is subject to limitations.

    EXCHANGE OFFER.

    The exchange of notes for the exchange notes pursuant to the exchange offer
will not constitute a taxable exchange for U.S. federal income tax purposes. As
a result,

        (1) a U.S. Holder will not recognize taxable gain or loss as a result of
    exchanging notes for exchange notes pursuant to the exchange offer,

        (2) the holding period of the exchange notes will include the holding
    period of the notes exchanged therefor, and

        (3) the adjusted tax basis of the exchange notes will be the same as the
    adjusted tax basis of the notes exchanged therefor immediately before such
    exchange.

The filing of a shelf registration statement should not result in a taxable
exchange to us or any holder of a note.

    BACKUP WITHHOLDING AND INFORMATION REPORTING.

    In general, a U.S. Holder will be subject to backup withholding at the rate
of 31.0% with respect to interest, principal and premium, if any, paid on a note
or exchange note, and the proceeds of a sale of a note or exchange note, unless
the U.S. Holder

        (1) is an entity that is exempt from withholding, including corporations
    and tax-exempt organizations, and, when required, demonstrates this fact, or

        (2) provides the payor with its taxpayer identification number ("TIN")
    which for an individual would be the holder's social security number,
    certifies that the TIN provided to the payor is correct and that the holder
    has not been notified by the IRS that it is subject to backup withholding
    due to underreporting of interest or dividends, and otherwise complies with
    applicable requirements of the backup withholding rules.

                                      122
<PAGE>
In addition, such payments of principal, premium and interest to, and the
proceeds of a sale of a note or exchange note by, U.S. Holders that are not
exempt entities will generally be subject to information reporting requirements.
The amount of any backup withholding from a payment to a U.S. Holder will be
allowed as a credit against such U.S. Holder's United States federal income tax
liability and may entitle such U.S. Holder to a refund, provided that the
required information is furnished to the IRS.

UNITED STATES FEDERAL INCOME TAXATION OF NON-U.S. HOLDERS

    PAYMENTS OF INTEREST.

    In general, payments of interest on the notes or exchange notes by us or our
agent to a Non-U.S. Holder will not be subject to United States federal income
tax, or any withholding thereof except as described below under "--Backup
Withholding and Information Reporting," provided that either,

        (1) (a) the Non-U.S. Holder does not actually or constructively own
    10.0% or more of the total combined voting power of all classes of our stock
    entitled to vote,

            (b) the Non-U.S. Holder is not a controlled foreign corporation that
    is related to us, actually or constructively, through stock ownership,

           (c) the Non-U.S. Holder is not a bank described in Section
       881(c)(3)(A) of the Code, and

           (d) either

               (x) the Non-U.S. Holder certifies to us or our agent on IRS Form
           W-8 or a suitable substitute form, under penalties of perjury, that
           it is not a "United States person," as defined in the Internal
           Revenue Code, and provides its name and address, or

               (y) a financial institution such as a securities clearing
           organization, bank or other financial institution that holds
           customers' securities in the ordinary course of its trade or business
           and holds the notes or exchange notes on behalf of the Non-U.S.
           Holder certifies to us or our agent under penalties of perjury that
           such statement has been received from the Non-U.S. Holder by it or by
           a financial institution between it and the Non-U.S. Holder and
           furnishes us or our agent with a copy thereof, or

        (2) (a) the Non-U.S. Holder is entitled to the benefits of an income tax
    treaty under which interest on the notes or exchange notes is exempt from
    United States federal withholding tax and provides us or our paying agent
    with a properly executed IRS Form 1001 or successor form claiming the
    exemption, or

            (b) the interest paid on the note is not subject to withholding tax
    because it is effectively connected with the beneficial owner's conduct of a
    trade or business in the United States and the beneficial owner provides us
    or our paying agent with a properly executed IRS Form 4224, or successor
    form.

    Treasury regulations issued on October 6, 1997 and revised on December 31,
1998 (the "New Withholding Regulations") alter the rules described above in
certain respects. The New Withholding Regulations generally will be effective
with respect to payments made after December 31, 2000, regardless of the issue
date of the instrument with respect to which such payments are made. The New
Withholding Regulations generally will not materially alter the certification
rules described in (1)(d) of the preceding paragraph, but will provide
alternative methods for satisfying such requirements.

    In addition, the New Withholding Regulations may require that a Non-U.S.
Holder obtain a United States taxpayer identification number and make certain
certifications if the Non-U.S. Holder wishes to claim exemption from, or a
reduced rate of, withholding under an income tax treaty. Each Non-U.S. Holder
should consult its own tax advisor regarding the application to such holder of
the New Withholding Regulations.

                                      123
<PAGE>
    SALE, EXCHANGE OR RETIREMENT OF THE EXCHANGE NOTES OR EXCHANGE EXCHANGE
     NOTES.

    A Non-U.S. Holder generally will not be subject to United States federal
income tax, or any withholding thereof except as described below under "--Backup
Withholding and Information Reporting," on gain realized on the sale, exchange,
redemption, retirement at maturity or other disposition of a note or exchange
note unless

        (1) such gain is effectively connected with the conduct by such holder
    of a trade or business in the United States,

        (2) in the case of gains derived by an individual, such individual is
    present in the United States for 183 days or more in the taxable year of the
    disposition and certain other conditions are met and

        (3) the Non-U.S. Holder is subject to tax according to the provisions of
    United States federal income tax law applicable to certain expatriates.

    EXCHANGE OFFER.

    The exchange of notes for the exchange notes pursuant to the exchange offer
will not be treated as a taxable exchange for United States federal income tax
purposes. As a result, there will be no U.S. federal income tax consequences to
Non-U.S. Holders exchanging the notes for the exchange notes pursuant to the
exchange offer.

    BACKUP WITHHOLDING AND INFORMATION REPORTING.

    Under current Treasury regulations, backup withholding and information
reporting do not apply to payments made by us or our paying agent to Non- U.S.
Holders if the certification described in (1)(d) under "--Payments of Interest"
above is received, provided that the payor does not have actual knowledge that
the holder is a United States person.

    In addition, backup withholding and information reporting generally will not
apply if payments on a note or exchange note are made to a Non-U.S. Holder by or
through

        (1) the foreign office of a custodian, nominee or other agent of such
    Non-U.S. Holder, or

        (2) if the foreign office of a "broker," as defined in applicable
    Treasury regulations, pays the proceeds of the sale of a note or exchange
    note to the seller thereof.

    Information reporting requirements, but, currently, not backup withholding,
will apply, however, to a payment by or through a foreign office of a custodian,
nominee, agent or broker that is, for United States federal income tax purposes:

        (1) a United States person;

        (2) a controlled foreign corporation; or

        (3) a foreign person that derives 50.0% or more of its gross income for
    certain periods from the conduct of a trade or business in the United
    States, unless such custodian, nominee, agent or broker has documentary
    evidence in its records that the holder is a non-U.S. person and certain
    other conditions are met, or the holder otherwise establishes an exemption.
    Payment by a U.S. office of a custodian, nominee, agent or broker is subject
    to both backup withholding at a rate of 31.0% and information reporting
    unless the holder certifies, under penalties of perjury, that it is not a
    United States person and the payor does not have actual knowledge to the
    contrary, or the holder otherwise establishes an exemption. A Non-U.S.
    Holder may obtain a refund or a credit against such Non-U.S. Holder's United
    States federal income tax liability of any amounts withheld under the backup
    withholding rules, provided the required information is furnished to the
    IRS.

                                      124
<PAGE>
    The New Withholding Regulations revise, substantially in certain respects,
the procedures that withholding agents and payees must follow to comply with, or
to establish an exemption from, the information reporting and backup withholding
provisions for payments after December 31, 2000. Each Non-U.S. Holder should
consult its own tax advisor regarding the application to such holder of the New
Withholding Regulations.

    ESTATE TAX.

    Notes or exchange notes held at the time of death, or theretofore
transferred subject to certain retained rights or powers, by an individual who
at the time of death is a Non-U.S. Holder will not be included in such holder's
gross estate for U.S. federal estate tax purposes, provided that,

        (1) the individual does not actually or constructively own 10% or more
    of the total combined voting power of all classes of our stock entitled to
    vote, and

        (2) the income on the exchange notes or exchange notes is not
    effectively connected with the conduct of a United States trade or business
    by the individual.

                              PLAN OF DISTRIBUTION

    Any broker-dealer that acquired outstanding notes for its own account as a
result of market-making activities or other trading activities may be deemed to
be an "underwriter" under the Securities Act. Each broker-dealer that receives
exchange notes for its own account in exchange for outstanding notes, where such
outstanding notes were acquired by such broker-dealer as a result of
market-making activities or other trading activities, must acknowledge that it
will deliver a prospectus meeting the requirements of the Securities Act in
connection with any resale of such outstanding notes. The letter of transmittal
states that by so acknowledging and by delivering a prospectus, a broker-dealer
will not be deemed to admit that it is an "underwriter" within the meaning of
the Securities Act. This prospectus, as it may be amended or supplemented from
time to time, may be used by a broker-dealer in connection with any resale of
the exchange notes received in exchange for outstanding notes where such
outstanding notes were acquired by such broker-dealer as a result of
market-making or other trading activities. We agreed that, for a period of 180
days after the expiration date, we will make this prospectus available to any
broker-dealer for use in connection with any such resale. A broker-dealer which
delivers such a prospectus to purchasers in connection with such resales will be
subject to certain of the civil liability provisions under the Securities Act
and will be bound by the provisions of the registration rights agreement
(including certain indemnification rights and obligations).

    We will not receive any proceeds from any sale of exchange notes by
broker-dealers or others. Exchange notes received by broker-dealers for their
own account pursuant to the exchange offer may be sold from time to time in one
or more transactions in the over-the-counter market, in negotiated transactions,
through the writing of options on the exchange notes or a combination of such
methods of resale, at market prices prevailing at the time of resale, at prices
related to such prevailing market prices or negotiated prices. Any such resale
may be made directly to purchasers or to or through broker-dealers and/ or
purchasers of any such exchange notes. Any broker-dealer that resells exchange
notes that were received by it for its own account pursuant to the exchange
offer and any broker or dealer that participates in a distribution of such
exchange notes may be deemed to be an "underwriter" within the meaning of the
Securities Act and any profit on any such resale of exchange notes and any
commission or concessions received by any such persons may be deemed to be
underwriting compensation under the Securities Act. The letter of transmittal
states that by acknowledging that it will deliver, and by delivering, a
prospectus as required, a broker-dealer will not be deemed to admit that it is
an "underwriter" within the meaning of the Securities Act.

    For a period of 180 days from the expiration date, we will send a reasonable
number of additional copies of this prospectus and any amendment or supplement
to this prospectus to any broker-dealer that

                                      125
<PAGE>
requests such documents in the letter of transmittal. We will pay all the
expenses incident to the exchange offer (which shall not include the expenses of
any holder in connection with resales of the exchange notes). We have agreed to
indemnify the initial purchasers and any broker-dealers participating in the
exchange offer against certain liabilities, including liabilities under the
Securities Act.

    Certain legal matters relating to the validity of the exchange notes offered
hereby will be passed upon on behalf of the Company by Paul, Hastings, Janofsky

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholder of
Atrium Companies, Inc.:

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, of stockholder's equity and of cash flows
present fairly, in all material respects, the financial position of Atrium
Companies, Inc. and its subsidiaries at December 31, 1998 and 1997, and the
results of their operations and their cash flows for the years then ended and
each of the two periods ended December 31, 1996 and October 25, 1996, in
conformity with generally accepted accounting principles. 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 of these statements in accordance with
generally accepted auditing standards which 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,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                  (DOLLARS IN THOUSANDS, EXCEPT SHARE AMOUNTS)

1. ORGANIZATION, BUSINESS AND BASIS OF PRESENTATION:

    Atrium Companies, Inc. (the "Company") is engaged in the manufacture and
sale of doors, windows and various building materials throughout the United
States.

    Prior to October 2, 1998, the Company's historical financial statements as
previously filed with the Securities and Exchange Commission included its
operations and the operations of its wholly-owned subsidiaries, Atrium Door and
Window Company of the Northeast, Atrium Door and Window Company of New England,
Atrium Door and Window Company of New York (collectively "ADW--Northeast"),
Atrium Door and Window Company--West Coast ("ADW--West Coast") and Atrium Door
and Window Company of Arizona ("ADW--Arizona"). On October 2, 1998, pursuant to
an acquisition and merger (the "Recapitalization" or "reverse acquisition") as
more fully described in Note 3, the Company's indirect Parent (D and W)
contributed the assets of Wing Industries Holdings, Inc. and its subsidiary Wing
Industries, Inc. (collectively "Wing") and Door Holdings, Inc. and its
subsidiaries R.G. Darby Company, Inc. and Total Trim, Inc. (collectively
"Darby") to the Company.

    As Wing was determined to be the acquiror in the reverse acquisition, the
historical financial statements of the Company (prior to October 3, 1998) were
replaced with the historical financial statements of Wing. As a result, the
statement of operations for 1998 only includes the operations of the Company and
Darby from October 3 through December 31. The statements of operations for the
year ended December 31, 1997, the periods ended December 31, 1996 and October
25, 1996 only include the operations and accounts of Wing and its predecessor.
Wing was acquired by the current controlling shareholders on October 25, 1996.
The December 31, 1998 balance sheet includes the accounts of the Company, Wing,
Darby and each of their respective subsidiaries. The December 31, 1997 balance
sheet only includes the accounts of Wing.

    Following is a comparison of the actual results for the Company, Wing and
Darby prior to October 3, 1998, to unaudited pro forma information for the same
period assuming the reverse acquisition had taken place as of January 1, 1997:

                  (DOLLARS IN THOUSANDS, EXCEPT SHARE AMOUNTS)

2. SIGNIFICANT ACCOUNTING POLICIES:

    BASIS OF CONSOLIDATION

    The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. All significant intercompany transactions and
balances have been eliminated in consolidation.

    INDUSTRY SEGMENT

    The Company operates in a single industry segment, the fabrication,
distribution and installation of doors and windows and related components.

    REVENUE RECOGNITION

    Revenue from the sale of doors and windows and related components is
recorded at the time of delivery to the customer. Allowances are established to
recognize the risk of sales returns from customers and estimates of warranty
costs.

    CASH AND CASH EQUIVALENTS

    The Company considers all highly-liquid investments with original maturities
of three months or less to be cash equivalents. At December 31, 1998, the
Company had $4,012 of bank overdrafts that were reclassified into Accounts
Payable.

    EQUITY SECURITIES--AVAILABLE FOR SALE

    Investments in equity securities--available for sale are carried at market
based on quoted market prices, with unrealized gains (losses) recorded in
stockholder's equity.

    CONCENTRATIONS OF CREDIT RISK

    Financial instruments, which potentially expose the Company to
concentrations of credit risk, consist primarily of trade accounts receivable.
The Company's customers are located in all 50 states and in 6 different
countries. The Company performs ongoing credit evaluations of its customers'
financial condition and generally requires no collateral. The Company
establishes an allowance for doubtful accounts based upon factors surrounding
the credit risk of specific customers, historical trends and other information.
Two customers accounted for approximately 58% and 65% of gross sales for 1998
and 1997 and 55% for the periods ended December 31, 1996 and October 25, 1996,
respectively.

    INVENTORIES

    Inventories are valued at the lower of cost (last-in, first-out or "LIFO")
or market. Work-in-process and finished goods inventories consist of materials,
labor and manufacturing overhead. Inventory costs include direct materials,
labor and manufacturing overhead. Management believes that the LIFO method
results in a better matching of current costs with current revenues.

2. SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    PROPERTY, PLANT AND EQUIPMENT

    Property, plant and equipment is stated at cost less accumulated
depreciation. The Company depreciates the assets principally on a straight-line
basis for financial reporting purposes over their estimated useful lives, as
follows:

<TABLE>

                                                                                ESTIMATED
                                                                               USEFUL LIFE
                                                                               -----------
<S>                                                                            <C>
Buildings and improvements...................................................   5-40 years
Machinery and equipment......................................................   3-12 years
</TABLE>

    Gains or losses on disposition are based on the net proceeds and the
adjusted carrying amount of the assets sold or retired. Expenditures for
maintenance, minor renewals and repairs are expensed as incurred, while major
replacements and improvements are capitalized.

    GOODWILL

    Goodwill represents the excess of cost over fair market value of net assets
acquired. Goodwill is being amortized over 40 years on a straight-line basis.
Management continually reviews the carrying value of goodwill for recoverability
based on anticipated undiscounted cash flows of the assets to which it relates.
The Company considers operating results, trends and prospects of the Company, as
well as competitive comparisons. The Company also takes into consideration
competition within the building materials industry and any other events or
circumstances which might indicate potential impairment. When goodwill is
determined not to be recoverable, an impairment is recognized as a charge to
operations.

    CAPITALIZED SOFTWARE COSTS

    The Company capitalizes internal employee costs and external consulting
costs associated with implementing and developing software for internal use.
Internal costs capitalized include payroll and payroll-related costs for
employees who are directly associated with the development, modification and
implementation of the software. External costs capitalized include direct
expenses related to consulting and other professional fees consumed in
developing, modifying and implementing the software. Capitalization of costs
occurs upon the completion of the preliminary project stage and when management
believes it is probable a project will be completed and the software will be
used to perform the function intended. Amortization begins when the software is
put into place and is calculated on a straight-line basis over three years.
Management continually reviews the carrying value and expected functionality of
the accumulated costs for potential impairment. When it is no longer probable
that computer software being developed will be completed, modified or placed in
service, the assets, carrying value will be adjusted to the lower of cost or
fair value.

    Unamortized capitalized software costs at December 31, 1998 and 1997 were
$3,665 and $0, respectively. Amortization expense for 1998 was $304.

    INCOME TAXES

    The provision for income taxes is based on pretax income as reported for
financial statement purposes. Deferred income taxes are provided in accordance
with the liability method of accounting for

income taxes to recognize the tax effects of temporary differences between
financial statement and income tax accounting.

    FORWARD COMMITMENTS

    The Company periodically enters into forward commitments to hedge price
variances in materials. Changes in the market value of forward commitments are
recognized in income when the effects of the related charges in the hedged items
are recognized.

    USE OF ESTIMATES

    The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the dates of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. Actual results could differ from these estimates. Significant
estimates are used in calculating bad debt, workers' compensation and warranty
accruals, and in recognizing deferred tax assets and liabilities.

    ADVERTISING COSTS

    Advertising costs are expensed when incurred and were $2,841, $1,800, $128
and $1,222 for 1998 and 1997 and the periods ended December 31, 1996 and October
25, 1996, respectively. These costs are reflected in "selling, delivery, general
and administrative" in the consolidated statements of operations.

    OTHER COMPREHENSIVE INCOME

    In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 130 ("FAS 130") "Reporting
Comprehensive Income." FAS 130 requires that all items that are required to be
recognized under accounting standards as components of comprehensive income be
reported in a financial statement that is displayed with the same prominence as
other financial statements. FAS 130 is effective for financial statement periods
beginning after December 15, 1997. The Company adopted FAS 130 beginning January
1, 1998. The Company had no comprehensive income for all periods presented prior
to January 1, 1998.

    RECENT ACCOUNTING PRONOUNCEMENTS

    In March 1998, the Accounting Standards Executive Committee of the American
Institute of Certified Public Accountants ("AcSEC") Issued Statement of Position
98-1 ("SOP 98-1") "Accounting for the Costs of Computer Software Developed or
Obtained for Internal Use" that is effective for reporting periods beginning
after December 15, 1998, but provides for earlier application if certain
conditions are met. The Company has applied the provisions of SOP 98-1 in its
financial statements for the year ended December 31, 1998 and its adoption had
no material effect on the Company's consolidated financial position or results
of operations.

    In June 1998, the FASB issued Statement of Financial Accounting Standards
No. 133 ("FAS 133") "Accounting for Derivative Instruments and Hedging
Activities" that is effective for all fiscal quarters of fiscal years beginning
after June 15, 1999. The Company will implement the provisions of FAS 133 as

effect on the Company's consolidated financial position or results of
operations.

    RECLASSIFICATIONS

    Certain reclassifications have been made to the 1997 and 1996 balances to
conform to the 1998 presentation.

3. THE REVERSE ACQUISITION (RECAPITALIZATION):

    On August 3, 1998, D and W ("Parent"), entered into an Agreement and Plan of
Merger (the "Merger Agreement") with Atrium Corporation ("Corp"), the parent
company of the Company and other necessary parties to acquire all of the
outstanding capital stock of Corp for $225.0 million, through a series of
transactions (the "Recapitalization") described below. Corp owned 100% of the
outstanding capital stock of the Company prior to the Merger discussed below. GE
Investment Private Placement Partners II, a limited partnership ("GEIPPPII"),
and Ardatrium L.L.C. ("Ardatrium") formed Parent by acquiring all of its
outstanding common stock for an aggregate purchase price of $50.0 million.
GEIPPPII is a private equity partnership affiliated with GE Investments, a
wholly-owned investment management subsidiary of General Electric Company.
Ardatrium is an affiliate of Ardshiel, Inc. ("Ardshiel"), a private equity
investment firm based in New York.

    The acquisition of Corp by Parent was effected through the merger on October
2, 1998 of a wholly owned subsidiary of Parent, with and into Corp (the
"Merger") pursuant to the terms of the Merger Agreement. Prior to the Merger,
Parent contributed $50.0 million to the wholly-owned subsidiary in exchange for
all of its outstanding common stock. As a result of the Merger, Corp became a
direct wholly-owned subsidiary of Parent, and the Company became an indirect
wholly owned subsidiary of Parent.

    Prior to the Merger, GEIPPPII and Ardshiel held investments in debt and
equity securities of Wing and Darby. Immediately prior to the consummation of
the Merger, all of the outstanding subordinated debt and associated warrants to
purchase common stock of Wing and Darby were converted into common stock of Wing
and Darby, respectively. The stockholders of Wing and Darby contributed their
common stock in Wing and Darby to Parent in exchange for common stock of Parent.
Immediately after the consummation of the Merger, Parent contributed all of the
common stock of Wing and Darby to Corp, which in turn contributed such stock to
the Company.

    Upon completion of the Recapitalization, GEIPPPII and Ardshiel and its
affiliates beneficially owned approximately 96.7% of the outstanding common
stock of Parent with management owning the remaining 3.3%.

    Pursuant to the terms of the Merger Agreement, all of the outstanding equity
securities of Corp were converted into the right to receive the merger
consideration of $94.2 million (the "Merger Consideration") in cash, net of
transaction costs of $5.4 million, outstanding indebtedness of $122.7 million
and $2.7 million of equity securities of Corp, owned by certain members of
management of Corp, which were converted into comparable equity securities of
Parent. The Merger Consideration was funded with (i) the $50.0 million in cash
that became an asset of Corp in the Merger, (ii) $20.0 million in cash proceeds
from the issuance of Senior Discount Debentures due 2010 by Corp. to GEIPPPII
and Ardatrium (the "Discount Debentures"), (iii) approximately $24.0 million in
cash proceeds from a loan from the Company (the

"Intercompany Loan") which was funded by a portion of the proceeds of a term
loan to the Company under the Credit Facility (see Note 9), and (iv) $0.2
million in cash proceeds from the issuance of common stock of Parent to certain
members of management of Corp followed by a capital contribution of such
proceeds by Parent to Corp.

    The acquisition of Corp by Parent and the Merger was accounted for as a
reverse acquisition. As Wing's shareholder group received the largest ownership
interest in Parent, Wing was determined to be the "accounting acquiror" in the
reverse acquisition. As a result, purchase accounting was applied to the assets
and liabilities of the Company. The purchase price was allocated to the
Company's assets and liabilities as follows:

    The purchase price includes cash paid of $120,977, including the retirement
of certain indebtedness, and the assumption of debt and accrued interest
$104,023

    The purchase method of accounting was also applied to the net assets of Wing
and Darby to the extent minority interest was acquired. Goodwill was increased
by $1,247 and $242 for Wing and Darby, respectively.

4. ACQUISITION OF DOOR DIVISION OF SUPER MILLWORK, INC.

    On November 10, 1997, Wing purchased certain assets of the Door Division of
Super Millwork, Inc. (SMI), a New York corporation for $12,500, including
contingent payments of $2,500 based on future operating results. The total cost
of the acquisition including transaction costs incurred aggregated $13,444. The
purchase price was funded with borrowings under a line of credit of
approximately $194, term loan borrowings of $6,750 and the issuance of
exchangeable subordinated notes of $4,000 with warrants.

5. FAIR VALUE OF FINANCIAL INSTRUMENTS:

    In accordance with Statement of Financial Accounting Standards No. 107 ("FAS
107") "Disclosures About Fair Value of Financial Instruments," the following
methods have been used in estimating fair value disclosures for significant
financial instruments of the Company.

    Estimated fair value amounts have been determined by the Company using
available market information and appropriate valuation methodologies. Due to the
fact that considerable judgment is required to interpret market data to develop
the estimates of fair value, the estimates presented are not necessarily
indicative of the amounts that could be realized in a current market exchange.

    Cash and cash equivalents--The carrying amounts reported in the balance
    sheet approximate the fair value.

    Equity securities--available for sale--The carrying amounts that are
    reported in the balance sheet approximate the fair value based on quoted
    market prices.

    Notes payable--The fair value of the Company's notes is based on quoted
    market prices. The carrying value of notes payable, other than the
    exchangeable subordinated notes and the senior subordinated notes,
    approximate fair value due to the floating nature of the interest rates.
    Management estimates that the effective interest rate for the exchangeable
    subordinated note approximates market for similar instruments with
    comparable maturities. The senior subordinated notes of $29,070 are valued
    at $29,361 as of December 31, 1998 based on quoted market prices.

    Interest Rate Swaps--The Company has entered into two interest rate swap
    agreements whereby the Company will pay the counterparties interest at a
    fixed rate and the counterparties will pay the Company interest at a
    floating rate equal to the three-month LIBOR interest rate. The fair value

banks and revolving line of credit existing at December 31, 1997 and through
October 2, 1998, were repaid or converted in connection with the

    The note agreements existing prior to the merger contained certain
covenants, including, among others, requirements that the Company comply with
certain financial and operational results and ratios. In addition, the loan
agreements placed certain limitations on the ability to pay dividends, to incur
indebtedness, to change its present method of doing business, to make certain
investments (including capital expenditures) or to sell assets. Substantially

the BHF-Bank agreements. The $10,000 and $6,750 term loans contained "excess
cash flow" provisions mandating additional principal payments if certain cash
flow targets were met during each fiscal year. No additional principal payments
were required as of December 31, 1997.

    The Company entered into a Credit Agreement (the "Credit Agreement"), dated
as of October 2, 1998 with Bank Boston, as administrative agent (the
"Administrative Agent") and Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner &
Smith Incorporated, as lead arranger, syndication agent and documentation agent.

    The Credit Agreement provides for three separate facilities (the
"Facilities") consisting of two term loans (referred to individually as "Term
Loan B" and "Term Loan C", and collectively as the "Term Loans") and a revolving
credit facility with a letter of credit sub-facility (the "Revolving Facility",
together with the Term Loans, the "Loans"). The Revolving Facility is in the
amount of $30,000, of which $5,000 is available under a letter of credit
sub-facility. The Revolving Facility has a maturity date of June 30, 2004.

    All amounts outstanding under the Credit Agreement are secured by (i) a
pledge of all of the capital stock and intercompany notes of the Company and its
direct and indirect subsidiaries existing October 2, 1998 or thereafter and (ii)
an interest in substantially all of the tangible and intangible properties and
assets (including substantially all contract rights, certain real property
interests, trademarks, tradenames, equipment and proceeds of the foregoing) of
Corp, the Company and their respective direct and indirect domestic subsidiaries
existing on the October 2, 1998 or thereafter created or acquired (the "Domestic
Subsidiaries"). Corp and each of the Domestic Subsidiaries have unconditionally
guaranteed, on a joint and several basis, all obligations of the Company under
the Credit Agreement.

    The Term Loans have an "excess cash flows" provision mandating additional
principal payments if certain cash flows targets are met during the year. No
additional principal payments are required as of December 31, 1998 related to
this provision.

    The Company is required to pay certain commitment fees in connection with
the Credit Agreement based upon the average daily unused portion of the
Revolving Facility, certain fees assessed in connection with the issuance of
letters of credit as well as other fees specified in the Credit Agreement and
other documents related thereto.

    The Credit Agreement requires the Company to comply with certain covenants
which, among other things, include limitations on indebtedness, liens and
further negative pledges, investments, contingent obligations, dividends,
redemptions and repurchases of equity interests, mergers, acquisitions and asset
sales, capital expenditures, sale leaseback transactions, transactions with
affiliates, dividend and other payment restrictions affecting subsidiaries,
changes in business conducted, amendment of documents relating to other
indebtedness and other material documents, creation of subsidiaries, designation
of Designated Senior Indebtedness in respect of the Notes, and prepayment or
repurchase of other indebtedness. The Credit Agreement requires the Company to
meet certain financial tests pertaining to, interest coverage, fixed charge
coverage and leverage.

    The Credit Agreement contains customary events of default, including,
without limitation, payment defaults, covenant defaults, breaches of
representations and warranties, bankruptcy and insolvency, judgments, change of
control and cross-default with certain other indebtedness.

    SHAREHOLDER AGREEMENT

    GEIPPPII, Ardatrium and certain of its affiliates, and certain other
shareholders of Parent have entered into a Shareholder Agreement (the
"Shareholder Agreement"), dated as of October 2, 1998, which affect their
relative rights as shareholders of Parent.

    MANAGEMENT AGREEMENT

    Parent is a party to a Management Agreement (the "Management Agreement")
dated October 2, 1998 with Ardshiel. Pursuant to the Management Agreement,
Ardshiel provides advice to Parent and its subsidiaries with respect to business
strategy, operations and budgeting and financial controls ("Management
Services") in exchange for an annual fee of $1,300 plus expenses. Additionally,
the Management Agreement provides that, prior to entering into any transaction
that involves engaging a financial advisor to perform services in connection
with a sale or purchase of a business or entity or any financing including,
Parent or its subsidiaries must offer Ardshiel the opportunity to perform such
investment banking services, unless in the reasonable exercise of the business
judgment of the Board of Directors of Parent such engagement would result in a
conflict of interest or would otherwise be adverse to the interests of Parent or
such subsidiaries. Ardshiel shall receive a fee for any such services rendered
by Ardshiel to Parent or its subsidiaries which fee shall not be greater than 2%
of the total purchase or sale price for such business or entity and shall be
payable upon consummation of such sale or purchase. The consent of GEIPPPII is
required prior to the payment by Parent or any of its subsidiaries in paying
similar fees to other entities for similar services. Parent paid a closing fee
of approximately $3,375 upon the consummation of the Merger and paid Ardshiel's
fees and expenses in connection therewith. The Management Agreement will remain
in effect until October 2, 2008 and will automatically be renewed for one-year

days prior to the expiration of the initial or any extended term of the
agreement.

    FORWARD COMMITMENTS

    The Company has contracts with various suppliers to purchase aluminum for
use in the manufacturing process. The contracts vary from one to twelve months
and are at fixed quantities with fixed and floating prices. As of December 31,
1998, the Company had forward commitments totaling $2,623 for delivery through
December 1999 for 21.1 million pounds of aluminum, of which 3.6 million pounds
were at fixed prices, respectively. No amounts were outstanding as of December
31, 1997.

    CONTINGENCIES

    The Company is party to various claims, legal actions and complaints arising
in the ordinary course of business. In the opinion of management, all such
matters are without merit or are of such kind, or involve such amounts, that an
unfavorable disposition would not have a material effect on the consolidated
financial position, results of operations or liquidity of the Company.

    During 1993, factory employees voted to unionize and become members of
Amalgamated Clothing and Textile Workers Union. A three-year union contract was
executed during 1995 and extended for three additional years in 1998. In
addition, in connection with its Woodville, Texas operations, the Company is
party to collective bargaining arrangements due to expire in 2001.

    The Company is involved in various stages of investigation and cleanup
related to environmental protection matters, some of which relate to waste
disposal sites. The potential costs related to such matters and the possible
impact thereof on future operations are uncertain due in part to: the
uncertainty as to the extent of pollution; the complexity of Government laws and
regulations and their interpretations; the varying costs and effectiveness of
alternative cleanup technologies and methods; the uncertain level of insurance
or other types of recovery; and the questionable level of the Company's
involvement. The

13. COMMITMENTS AND CONTINGENCIES: (CONTINUED)
Company was named in 1988 as a potentially responsible party ("PRP") in two
superfund sites pursuant to the Comprehensive Environmental Response
Compensation and Liability Act of 1980, as amended (the Chemical Recycling, Inc.
site in Wylie, Texas, and the Diaz Refinery site in Little Rock, Arkansas). The
Company believes that based on the information currently available, including
the substantial number of other PRP's and relatively small share allocated to it
at such sites, its liability, if any, associated with either of these sites will
not have a material adverse effect on the Company's consolidated financial
position, results of operations or liquidity.

15. STOCK OPTIONS:

    The Wing Industries Holdings, Inc. Stock Option Plan (the "Plan") was
adopted on October 25, 1996 and amended on November 17, 1997 to provide certain
employees, officers and directors of Wing an opportunity to purchase Class A
voting common stock of Wing. Options available for grant under the Plan included
(1) "Incentive Stock Options" as defined in Section 422 of the Internal Revenue
Code of 1986, as amended and (2) Nonqualified Stock Options which were options
that did not constitute Incentive Stock Options.

    At December 31, 1997, Nonqualified Stock Options for a total of 14,483
shares of Wing's Class A voting common stock had been granted. During 1998, and
prior to the Recapitalization, 1,766 options were exercised. The remaining
12,717 options were exchanged for 2,528,314 options in the D and W Holdings,
Inc. 1998 Stock Option Plan (the "New Plan"). The Plan was terminated in
connection with the Recapitalization. No compensation expense was recorded
during 1997 or 1996.

    THE NEW PLAN

    In connection with the Recapitalization, the Board of Directors adopted the
New Plan authorizing the issuance of 11,991,142 options to acquire common stock
of the Company. Through December 31, 1998, the Board of Directors granted
11,735,941 options under the New Plan. All options granted under the New Plan
expire ten years from the date of grant, October 2, 1998.

    As of December 31, 1998, 1,756,924 options had been granted in three
tranches under the New Plan in replacement of certain of the options granted
under the Plan. These options consist of (a) options to purchase 692,861 shares
of common stock at an exercise price of $0.01 per share; (b) options to purchase
539,135 shares of common stock at an exercise price of $0.72 per share until
December 1, 1999, and then increasing 15% per year thereafter, until and
including December 1, 2000; and (c) options to purchase 524,928 shares of common
stock at an exercise price of $0.82 per share until December 1, 1999, and then

15. STOCK OPTIONS: (CONTINUED)
increasing 30% per year thereafter, until and including December 1, 2000. As of
December 31, 1998, 1,064,030 of these options were fully vested. The remaining
options vest on October 25, 1999, subject to accelerated vesting in the event
(a) the Company sells common stock in an offering registered with the Securities
and Exchange Commission which results in a Change of Control (as defined in the
New Plan); (b) the Company is merged or consolidated with another corporation in
a merger in which the surviving corporation has freely tradeable common stock;
(c) substantially all of the assets of the Company and its subsidiaries, taken
as a whole, are sold or otherwise transferred; or (iv) a plan of liquidation of
the Company of the optionee's employer is adopted.

    As of December 31, 1998, options of 771,390 with an exercise price of $1.25
had been granted under the New Plan that become exercisable only as such time at
(each such event, a "Value Event") (a) the Company sells common stock in an
offering registered with the Securities and Exchange Commission, which
constitutes a Qualifying Public Offering (as defined in the New Plan); (b) the
Company is merged or consolidated with another corporation in a merger in which
the surviving corporation has freely tradeable common stock; or (c)
substantially all of the assets of the Company and its subsidiaries, taken as a
whole, are sold or otherwise transferred.

    As of December 31, 1998, options of 832,314 had been granted that consisted
of two tranches: (a) - options to purchase 277,438 shares with an exercise price
of $0.83 per share to March 31, 1999 and then increasing 15% per year thereafter
and (b) - options to purchase 554,876 shares with an exercise price of $0.83 per
share to March 31, 1999 and then increasing 30% per year thereafter. For the 15%
and the 30% options, if the holder chooses not to exercise at time of vesting,
the strike price increases annually to the next level until expiration. At
December 31, 1998 none of these options were vested. The options vest equally in
one-third increments on January 9, 1999, 2000 and 2001, respectively.

    As of December 31, 1998, options of 221,725 with an exercise price of $1.65
had been granted that are exercisable only upon the occurrence of a Value Event.
These options vest at such time of occurrence of a value event.

    As of December 31, 1998, options of 8,153,588 options had been granted with
an exercise price of $1.00. On the anniversary of the grant date and prior to
termination of employment, 3,551,526 options will vest 25% and shall continue to
vest ratably as of and after the fourth anniversary date of grant. The remaining
4,602,062 options will vest 20% and shall continue to vest ratably as of and
after the fifth anniversary date of grant. The options expire ten years from the
date of grant.

    The Company recorded non cash stock option compensation expense of $1,038 in
1998 in connection with the difference between the fair value of the stock at
the date of issuance ($1.00) and the respective exercise prices of each of the
above grants.

    THE REPLACEMENT PLAN

    In addition to the New Plan, the Board of Directors adopted the D and W
Holdings, Inc. Replacement Stock Option Plan (the "Replacement Plan") to govern
the terms of certain options to purchase the Company's common stock which were
granted in replacement of outstanding options of Atrium Corp. in connection with
the Recapitalization. Under the Replacement Plan, options to purchase in
aggregate of 1,575,000 shares of the Company's common stock were granted in
exchange for outstanding options of Atrium Corp. which were not cashed out
pursuant to the Merger Agreement. The options granted

15. STOCK OPTIONS: (CONTINUED)
pursuant to the Replacement Plan vest ratably over a period of five years on
each anniversary date of the grant. The replacement options have an exercise
price of $0.01 per share.

    Upon termination of the optionee's employment, the Company shall have the
right to repurchase the options. In the event termination was for cause, the
price per option repurchased will be equal to the lesser of $1.00 per underlying
share and the market value per share of the Company's common stock, in either
case, minus $0.01 per share. If termination is for other than cause, the
repurchase price will differ for the vested and unvested portions. The unvested
portion will be reacquired at a purchase price equal to the lesser of the market
value per share and $1.00 per share, in each case, minus $0.01 per share and the
vested portion may be reacquired at a purchase price equal to the greater of the
market value per share or $1.00 per share, in each case, minus $0.01 per share.

    On October 2, 1998, the Company issued a warrant (the "Warrant") to the
President and Chief Executive Officer (the "Executive") of the Company. Pursuant
to the terms of the Warrant, the Executive is entitled to purchase 2,841,221
shares of common stock at any time subsequent to the Recapitalization. The
exercise price of the Warrant is $.01 per share. An additional 1,894,148 shares
may be purchased under the Warrant at an exercise price of $1.00, representing
the fair market value on the date of grant upon the realization of an 8.0%
internal rate of return. The 1,894,148 options vest ratably each day for three
years. The Warrant will terminate on October 2, 2008. The Company recorded non
cash compensation expense of $2,813 for 1998 in connection with the difference
between the fair market value of the stock at the date of issuance ($1.00) and
the exercise price ($.01).

    In addition, in exchange for certain warrants to purchase common stock of
Atrium Corp, the Executive received a warrant to purchase 1,000,000 shares of
the Company's common stock at a price of $.01 per share with a term of twenty
years.

    The following table summarizes the transactions of the New Plan and the
Replacement Plan for the years ended December 31, 1998 and 1997 and the period
ended December 31, 1996 (all outstanding options were granted to management of
the Company):

    The fair value of each stock option granted is estimated on the date of
grant using the minimum value method of option pricing with the following
weighted-average assumptions for grants in 1998 and 1997: dividend yield of
0.0%; risk-free interest rate of 7.0%; and the expected life of 10 years. (In
determining the "minimum value" SFAS 123 does not require the volatility of the
Company's common stock underlying the options to be calculated or considered
because the Company was not publicly-traded when the options were granted).

    If an event or value event as previously defined were to become probable,
the difference between the option price and the then fair market value would be
charged to earnings at that time.

    In 1995, the FASB issued FASB Statement No. 123 ("FAS 123") "Accounting for
Stock-Based Compensation" which, if fully adopted by the Company, would change
the methods the Company applies in recognizing the cost of the stock based
plans. Adoption of the cost recognition provisions of FAS 123 is optional and
the Company has decided not to elect the provisions of FAS 123. However, pro
forma disclosures as if the Company adopted the cost recognition provisions of
FAS 123 are required by FAS 123; however, there is no pro forma effect of
adopting the cost provisions of FAS 123 for the years ended December 31, 1998
and 1997 and the periods ended December 31, 1996 and October 25, 1996. In 1998,
1997 and 1996, the Company granted only nonqualified stock options and warrants
under the plans.

    Had the compensation cost for the Company's stock-based compensation plans
and warrants been determined consistent with FAS 123, the Company's net income
(loss) for 1998, 1997 and 1996 would have been ($3,122), $440 and $224,
respectively.

    The effects of applying FAS 123 in this pro forma disclosure are not
indicative of future amounts. FAS 123 does not apply to awards prior to 1995.

16. EMPLOYEE BENEFIT PLANS:

    Prior to the formation of Wing, management announced the curtailment of the
defined benefit pension plan covering substantially all employees. Upon receipt
of a favorable tax determination letter from the Internal Revenue Service,
settlement of the plan occurred during the period ended October 25, 1996, at
which time a liquidating distribution of $2,789 was made to the eligible
employees based on years of service and the employee's compensation during the
five consecutive years of employment in which compensation was the highest. In
addition, management retired the two nonqualified, unfunded and noncontributory
plans for the directors. Settlement of the plans occurred during the period
ended October 25, 1996 at which time a lump-sum payout of $801 was made to the
directors.

    The Company maintains an employees' savings plan under Section 401(k) of the
Internal Revenue Code (the "Code"). The Company makes discretionary matching
contributions equal to 50% of the first 4% of the employee's contribution. The
Company contributed $101, $85, $78 during 1998 and 1997 and the period ended
December 31, 1996, respectively.

    In connection with the Recapitalization, the Company maintains two
additional plans under Section 401(k) and 401 of the Code. Each plan provides
for discretionary contributions by the employer. The Plan covered by Section 401
of the Code does not provide for employee contributions. The Company contributed
$57 to the plans during the period from October 3, 1998 to December 31, 1998.

17. SUBSIDIARY GUARANTORS:

    In connection with the Company's Senior Subordinated Notes, the Company's
payment obligations under the Notes are fully and unconditionally guaranteed,
jointly and severally (collectively, the Subsidiary Guarantees) on a senior
subordinated basis by its wholly-owned subsidiaries: ADW-Northeast, ADW-Arizona,
ADW-West Coast, Wing and Darby (collectively, the Subsidiary Guarantors). The
Company has no non-guarantor direct or indirect subsidiaries. The operations
related to the assets of ADW-Northeast ADW-Arizona ADW-West Coast and Darby are
included since the reverse acquisition on October 2, 1998. The operations of
Wing are presented for all periods covered. The balance sheet information
includes all subsidiaries as of December 31, 1998 and only Wing as of December
31, 1997. In the opinion of management, separate financial statements of the
respective Subsidiary Guarantors would not provide additional material
information, which would be useful in assessing the financial composition of the
Subsidiary Guarantors. No single Subsidiary Guarantor has any significant legal
restrictions on the ability of investors or creditors to obtain access to its
assets in event of default on the Subsidiary Guarantee other than its
subordination to senior indebtedness.

    Following is summarized combined financial information pertaining to these
Subsidiary Guarantors:

18. SUBSEQUENT EVENTS:

    DELTA ACQUISITION

    On January 27, 1999, the Company acquired certain assets of Delta Millwork,
Inc., a privately held door pre-hanger located in Orlando, Florida, for $1,300.
The Company financed the acquisition through its revolving credit facility.

    The acquisition will be accounted for as a purchase in accordance with
Accounting Principles Board Opinion No. 16, "Business Combinations" ("APB 16").
The aggregate purchase price will be allocated to the underlying assets and
liabilities based upon their respective estimated fair market values at the date
of acquisition, with the remainder allocated to goodwill. Based on preliminary
estimates which will be finalized at a later date, the excess of purchase price
over the fair value of the net assets acquired ("goodwill") was approximately
$100, which will be amortized over 40 years. The results of operations for the
acquired business will be included in the Company's consolidated financial
statements beginning January 27, 1999.

    MANAGEMENT CHANGE

    On April 9, 1999, the Company completed a separation agreement with Randall
S. Fojtasek, President and Chief Executive Officer, whereby Mr. Fojtasek
resigned from the Company effective March 31, 1999. The Board of Directors has
nominated Jeff L. Hull, Executive Vice President and Chief Financial Officer,
and Ken L. Gilmer, Executive Vice President and Chief Operating Officer, to
oversee day-to-day operations and report directly to the Executive Committee of
the Board of Directors. The Company expects to take a charge of approximately
$1,750 in the first quarter of fiscal year 1999 for severance benefits related
to this management change.

    $175,000 SENIOR SUBORDINATED NOTES

    On May 10, 1999, the Company issued $175,000 of senior subordinated notes
due May 1, 2009. The notes are non-callable for five years, have a 10.50% stated
rate paid semi-annually and were issued at a discount of 98.496 to yield 10.75%
to maturity. The proceeds were used to fund the acquisitions of Heat, Inc. and
Champagne Industries, Inc., refinance certain indebtedness and pay fees and
expenses.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                            MARCH 31, 1999 AND 1998
                  (DOLLARS IN THOUSANDS, EXCEPT SHARE AMOUNTS)
                                  (UNAUDITED)

1.  BASIS OF PRESENTATION:

    The unaudited consolidated financial statements of Atrium Companies, Inc.
(the "Company") for the quarters ended March 31, 1999 and 1998, and as of March
31, 1999 and December 31, 1998 have been prepared in accordance with generally
accepted accounting principles for interim financial reporting, the instructions
to Form 10-Q, and Rule 10-01 of Regulation S-X. Accordingly, they do not include
all of the information and footnotes required by generally accepted accounting
principles for complete financial statements.

    These consolidated financial statements and footnotes should be read in
conjunction with the Company's audited financial statements for the fiscal years
ended December 31, 1998, 1997 and 1996 included in the Company's Form 10-K as
filed with the Securities and Exchange Commission on April 15, 1999. In the
opinion of management, all adjustments (consisting of normal recurring
adjustments) considered necessary for a fair presentation of the interim
financial information have been included. The results of operations for any
interim period are not necessarily indicative of the results of operations for a
full year. Certain prior period amounts have been reclassified to conform to the
current period presentation.

    In June 1998, the FASB issued Statement of Financial Accounting Standards
No. 133 ("FAS 133") "Accounting for Derivative Instruments and Hedging
Activities" that is effective for all fiscal quarters of fiscal years beginning
after June 15, 1999. The Company will implement the provisions of FAS 133 as
required. The future adoption of FAS 133 is not expected to have a material
effect on the Company's consolidated financial position or results of
operations.

    Prior to October 2, 1998, the Company's historical financial statements as
previously filed with the Securities and Exchange Commission included its
operations and the operations of its wholly-owned subsidiaries, Atrium Door and
Window Company of the Northeast, Atrium Door and Window Company of New England,
Atrium Door and Window Company of New York (collectively, "ADW-Northeast"),
Atrium Door and Window Company--West Coast ("ADW-West Coast) and Atrium Door and
Window Company of Arizona ("ADW-Arizona"). On October 2, 1998, pursuant to an
acquisition and merger (the "Recapitalization" or "reverse acquisition") as more
fully described in the Company's Form 10-K as filed with the Securities and
Exchange Commission on April 15, 1999, the Company's indirect Parent (D and W
Holdings, Inc.) contributed the stock of Wing Industries Holdings, Inc. and its
subsidiary Wing Industries, Inc. (collectively "Wing") and Door Holdings, Inc.
and its subsidiaries R.G. Darby Company, Inc. and Total Trim, Inc. (collectively
"Darby") to the Company.

    As Wing was determined to be the acquiror in a "reverse acquisition", the
historical financial statements of the Company (prior to October 3, 1998) were
replaced with the historical financial statements of Wing. As a result, the
statement of income for 1998 only includes the operations of the Company and
Darby from October 3, 1998 through December 31, 1998. The statements of income
for all periods prior to October 3, 1998 only include the operations and
accounts of Wing. Additionally, the operations of Delta Millwork, Inc. (renamed
R.G. Darby Company-South and Total Trim-South, collectively "Darby-South") are
included since the date of acquisition, January 27, 1999. The March 31, 1999
balance sheet includes the accounts of the Company, Wing, Darby, Darby-South and
each of their respective subsidiaries, while the December 31, 1999 balance sheet
includes the accounts of the Company, Wing, Darby and each of their respective
subsidiaries.

5.  CONTINGENCIES:

    The Company is party to various claims, legal actions, and complaints
arising in the ordinary course of business. In the opinion of management, all
such matters are without merit or are of such kind, or involve such amounts,
that an unfavorable disposition would not have a material adverse effect on the
consolidated financial position, results of operations or liquidity of the
Company.

    During 1993, factory employees voted to unionize and become members of the
Amalgamated Clothing and Textile Workers Union. A three-year union contract was
executed during 1995 and extended for three additional years in 1998. In
addition, in connection with its Woodville, Texas operations, the Company is
party to collective bargaining arrangements due to expire in 2001.

    The Company is involved in various stages of investigation and cleanup
related to environmental protection matters, some of which relate to waste
disposal sites. The potential costs related to such matters and the possible
impact thereof on future operations are uncertain due in part to: the
uncertainty as to the extent of pollution; the complexity of Government laws and
regulations and their interpretations; the varying costs and effectiveness of
alternative cleanup technologies and methods; the uncertain level of insurance
or other types of recovery; and the questionable level of the Company's
involvement. The Company was named in 1988 as a potentially responsible party
("PRP") in two superfund sites pursuant to the Comprehensive Environmental
Response Compensation and Liability Act of 1980, as amended (the Chemical
Recycling, Inc. site in Wylie, Texas, and the Diaz Refinery site in Little Rock,
Arkansas). The Company believes that based on the information currently
available, including the substantial number of other PRP's and relatively small
share allocated to it at such sites, its liability, if any, associated with
either of these sites will not have a material adverse effect on the Company's
financial position, results of operations or liquidity.

6.  ACQUISITION:

DELTA ASSET PURCHASE:

    On January 27, 1999, the Company acquired certain assets of Delta Millwork,
Inc., a privately held door pre-hanger located in Orlando, Florida, for
approximately $1,737 including fees and other transaction expenses. The Company
financed the acquisition through its revolving credit facility.

    The acquisition of Delta Millwork, Inc. has been accounted for as a purchase
in accordance with Accounting Principles Board Opinion No. 16, "Business
Combinations" ("APB 16"). The aggregate purchase price has been allocated to the
underlying assets and liabilities based upon their respective estimated fair
market values at the date of acquisition, with the remainder allocated to
goodwill, which will be amortized over 40 years. The results of operations for
the acquired business are included in the Company's consolidated financial
statements beginning January 27, 1999. The purchase price allocation,
preliminary in nature and subject to change, is as follows:

</TABLE>

7.  SUBSIDIARY GUARANTORS:

    In connection with the issuance of the Senior Subordinated Notes (the
"Notes"), the Company's payment obligations under the Notes are fully and
unconditionally guaranteed, jointly and severally (collectively, the Subsidiary
Guarantees) on a senior subordinated basis by its wholly-owned subsidiaries:
ADW-Northeast, ADW-West Coast, ADW-Arizona, Wing, Darby and Darby-South
(collectively, the Subsidiary Guarantors). The Company has no non-guarantor
direct or indirect subsidiaries. The operations related to the assets of
ADW-Northeast, ADW-West Coast, ADW-Arizona and Darby are included since the
reverse acquisition on October 2, 1998. The operations of Darby-South are
included since the date of acquisition, January 27, 1999. The operations of Wing
are presented for all periods covered. The balance sheet information includes
all subsidiaries as of March 31, 1999 and ADW-Northeast, ADW-West Coast,
ADW-Arizona and Darby as of December 31, 1998. In the opinion of management,
separate financial statements of the respective Subsidiary Guarantors would not
provide additional material information, which would be useful in assessing the
financial composition of the Subsidiary Guarantors. No single Subsidiary
Guarantor has any significant legal restrictions on the ability of investors or
creditors to obtain access to its assets in event of default on the Subsidiary
Guarantee other than its subordination to senior indebtedness.

8.  SUBSEQUENT EVENTS:

HEAT ACQUISITION

    On April 20, 1999, the Company entered into a stock purchase agreement to
acquire Heat, Inc., a privately held vinyl window and door company located in
Pittsburgh, Pennsylvania, for approximately $85,000. The Company expects to
finance the acquisition with a portion of the proceeds from the issuance of
$175,000 of senior subordinated notes (see below).

    The acquisition will be accounted for as a purchase in accordance with APB
16. The aggregate purchase price will be allocated to the underlying assets and
liabilities based upon their respective estimated fair market values at the date
of acquisition. Based on preliminary estimates which will be finalized at a
later date, the excess of purchase price over the fair value of the net assets
acquired ("goodwill") will be approximately $72,000, which will be amortized
over 40 years. The results of operations for the acquired business will be
included in the Company's operations subsequent to the completion of the
transaction, which is expected to be on or about May 17, 1999.

CHAMPAGNE ACQUISITION

    On May 10, 1999, the Company entered into a stock purchase agreement to
acquire Champagne Industries, Inc., a privately held vinyl window and door
company located in Denver, Colorado for approximately $3,500, excluding $500 to
be paid upon achievement of certain operational targets. The Company expects to
finance the acquisition with a portion of the proceeds from the issuance of
$175,000 of senior subordinated notes (see below).

$175,000 SENIOR SUBORDINATED NOTES

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholder of
Atrium Corporation:

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of income (loss), of stockholder's equity (deficit) and
of cash flows present fairly, in all material respects, the financial position
of Atrium Companies, Inc. and its subsidiaries (a wholly-owned subsidiary of
Atrium Corporation) at December 31, 1997 and 1996, and the results of their
operations and their cash flows for the period from January 1, 1998 to October
2, 1998 and the years ended December 31, 1997 and 1996, in conformity with
generally accepted accounting principles. 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 of these statements in accordance with generally accepted auditing
standards, which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES:

    Atrium Companies, Inc. (the "Company"), (formerly Fojtasek Companies, Inc.,
a Texas corporation), is engaged in the manufacture and sale of doors, windows
and various building materials throughout the United States. A significant
portion of the Company's sales relates to new home construction activity, which
is cyclical in nature.

    On July 3, 1995, the stockholders of Fojtasek Companies, Inc. ("Fojtasek")
executed a stock purchase agreement (the "Heritage Transaction") whereby all of
Fojtasek's common stock was acquired by FCI Holding Corp. ("FCI Holding"), a
Delaware holding company which was established in connection with the Heritage
Transaction. On September 30, 1996, Atrium Corporation ("Holding"), a Delaware
company which owned 100% of FCI Holding (which owned 100% of Fojtasek) acquired
Atrium Door and Window Company of the Northeast ("ADW--Northeast," formerly
Bishop), a manufacturer of vinyl replacement windows and doors and contributed
the capital stock of ADW--Northeast to Fojtasek (Note 15). On November 8, 1996,
in connection with the Hicks Muse Transaction (the "Hicks Muse Transaction"),
Fojtasek, which was a Texas corporation, was merged with and into FCI Holding.
The two companies were merged to achieve certain business objectives related to
brand-name recognition. The surviving Delaware corporation was renamed "Atrium
Companies, Inc.," (the "Company") which is a direct, wholly-owned subsidiary of
Holding. The merger was accounted for as a merger of companies under common
control and the assets were valued at historical cost.

  BASIS OF CONSOLIDATION AND PRESENTATION

    The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries, ADW--Northeast, acquired in September 1996,
and Atrium Door and Window Company-- West Coast ("ADW--West Coast," formerly H-R
Window Supply, Inc). ADW--Northeast refers to the combined consolidated results
of Atrium Door and Window Company of the Northeast (the merged companies
formerly named Vinyl Building Specialties of Connecticut, Inc. and Bishop
Manufacturing Company, Incorporated), its subsidiary Atrium Door and Window
Company of New England ("ADW-- New England" formerly Bishop Manufacturing
Company of New England, Inc.), and Atrium Door and Window Company of New York
("ADW--New York" formerly Bishop Manufacturing Co. of New York, Inc.) All
significant intercompany transactions and balances have been eliminated in
consolidation.

    The consolidated financial information for the nine months ended September
30, 1997 is unaudited. In the opinion of management, the accompanying unaudited
consolidated financial information and related notes thereto contain all
adjustments consisting only of normal, recurring adjustments, necessary to
present fairly the consolidated financial information as of September 30, 1997
and the operating results and cash flows for the nine months ended September 30,
1997. Certain information and footnote disclosures normally included in
financial statements prepared in accordance with generally accepted accounting
principles have been omitted pursuant to the rules and regulations of the
Securities and Exchange Commission. The results of operations for the periods
presented are not necessarily indicative of the results to be expected for the
full year.

    References to amounts used throughout these consolidated financial
statements for the period ended September 30, 1997 are unaudited.

1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
  INDUSTRY SEGMENT

    The Company operates in a single industry segment, the fabrication and
distribution of doors and windows and related components.

  REVENUE RECOGNITION

    Revenue from the sale of doors and windows and related components is
recorded at the time of delivery and billing to the customer. Allowances are
established to recognize the risk of sales returns from customers.

  CASH AND CASH EQUIVALENTS

    The Company considers all highly-liquid investments with original maturities
of three months or less to be cash equivalents.

  EQUITY SECURITIES--AVAILABLE FOR SALE

    Investments in equity securities--available for sale are carried at market
based on quoted market prices, with unrealized gains (losses) recorded in
stockholder's equity.

  ALLOWANCE FOR DOUBTFUL ACCOUNTS

    Accounts receivable are net of allowances for doubtful accounts of $608 and
$1,497 as of December 31, 1997 and 1996, respectively.

  PROVISION FOR WARRANTY CLAIMS

    Estimated warranty costs are provided at the time of the sale of the
warranted product.

  CONCENTRATIONS OF CREDIT RISK

    Financial instruments, which potentially expose the Company to
concentrations of credit risk, consist primarily of trade accounts receivable.
The Company's customers are concentrated in the southern regions of the U.S. and
focus upon the distribution and sale of building products. Sales in the state of
Texas accounted for approximately 38.3% of revenue in 1997. The Company performs
ongoing credit evaluations of its customers' financial condition and generally
requires no collateral. The Company establishes an allowance for doubtful
accounts based upon factors surrounding the credit risk of specific customers,
historical trends, and other information. The Company does not believe it is
dependent upon any single customer. No single customer accounted for more than
10% of sales in 1998, 1997 or 1996.

  INVENTORIES

    Inventories are valued at the lower of cost (last-in, first-out or "LIFO")
or market. Management believes that the LIFO method results in a better matching
of current costs with current revenues.

1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
  PROPERTY, PLANT AND EQUIPMENT

    Property, plant and equipment is stated at cost less accumulated
depreciation. Prior to January 1, 1997 the Company provided for depreciation and
amortization using straight-line and accelerated methods. For all assets
acquired subsequent to January 1, 1997 the Company depreciates the assets on a
straight-line basis over their estimated useful lives, as follows:

<TABLE>

                                                                  ESTIMATED
                                                                 USEFUL LIFE
                                                                 -----------
Buildings and improvements.....................................  5-40 years
<S>                                                              <C>
Machinery and equipment........................................  3-12 years
</TABLE>

    Gains or losses on disposition are based on the net proceeds and the
adjusted carrying amount of the assets sold or retired. Expenditures for
maintenance, minor renewals and repairs are expensed as incurred, while major
replacements and improvements are capitalized.

  GOODWILL

    Goodwill represents the excess of cost over fair market value of net assets
acquired. Goodwill is being amortized over 40 years on a straight-line basis.
Amortization expense of $655, $340 and $75 was recorded for the period ended
October 2, 1998 and for the years ended December 31, 1997 and 1996,
respectively. Accumulated amortization at December 31, 1997 and 1996 was $415
and $75, respectively. Management continually reviews the carrying value of
goodwill for recoverability based on anticipated undiscounted cash flows of the
assets to which it relates. The Company considers operating results, trends and
prospects of the Company, as well as competitive comparisons. The Company also
takes into consideration competition within the building materials industry and
any other events or circumstances which might indicate potential impairment.
When goodwill is determined not to be recoverable, an impairment is recognized
as a charge to operations to the extent the carrying value of related assets
(including goodwill) exceeds the fair value of the related assets.

  CAPITALIZED SOFTWARE COSTS

    The Company capitalizes internal employee costs and external consulting
costs associated with implementing and developing software for internal use.
Internal costs capitalized include payroll and payroll-related costs for
employees who are directly associated with the development, modification and
implementation of the software. External costs include direct expenses related
to consulting and other professional fees consumed in developing, modifying and
implementing the software. Capitalization of costs occurs upon the completion of
the preliminary project stage and when management believes it is probable a
project will be completed and the software will be used to perform the function
intended. Amortization begins when the software is put into place and is
calculated on a straight-line basis over five years. Management continually
reviews the carrying value and expected functionality of the accumulated costs
for potential impairment. When it is no longer probable that computer software
being developed will be completed, modified or placed in service, the assets
carrying value will be adjusted to the lower of cost or fair value.

                  (DOLLARS IN THOUSANDS, EXCEPT SHARE AMOUNTS)

1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
  INCOME TAXES

    The provision for income taxes is based on pretax income as reported for
financial statement purposes. Deferred income taxes are provided in accordance
with the liability method of accounting for income taxes to recognize the tax
effects of temporary differences between financial statement and income tax
accounting.

  FORWARD COMMITMENTS

    The Company periodically enters into forward commitments to hedge price
variances in materials. Changes in the market value of forward commitments are
recognized in income when the effects of the related charges in the hedged items
are recognized.

  USE OF ESTIMATES

    The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the dates of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. Actual results could differ from these estimates. Significant
estimates are used in calculating allowance for bad debt, workers' compensation
and warranty accruals, and deferred tax assets and liabilities.

2. FAIR VALUE OF FINANCIAL INSTRUMENTS:

    In accordance with Statement of Financial Accounting Standards (SFAS) No.
107, "Disclosures About Fair Value of Financial Instruments," the following
methods have been used in estimating fair value disclosures for significant
financial instruments of the Company.

    Estimated fair value amounts have been determined by the Company using
available market information and appropriate valuation methodologies. Since
considerable judgment is required to interpret market data to develop the
estimates of fair value, the estimates presented are not necessarily indicative
of the amounts that could be realized in a current market exchange.

    Cash and cash equivalents--The carrying amounts reported in the balance
    sheet approximate the fair value.

    Equity securities--available for sale--The carrying amounts that are
    reported in the balance sheet approximate the fair value based on quoted
    market prices.

    Notes payable--The fair value of the Company's notes is based on quoted
    market prices.

    Forward aluminum contracts--The unrealized gains and losses are based on
    quotes for aluminum as reported on the London Metal Exchange.

    In November 1996, the Company issued $100,000 aggregate principal amount of
10 1/2% Senior Subordinated Notes (the "Notes") due November 15, 2006 under the
Indenture dated as of November 27, 1996. Interest on the Notes is payable
semiannually on May 15 and November 15 of each year, commencing on May 15, 1997.
The Notes mature on November 15, 2006. The Company may redeem the Notes based on
certain triggering events. In addition, under certain circumstances the Company
will be obligated to make an offer to repurchase the Notes at 100% of the
principal amount, plus accrued and unpaid interest to the date of repurchase,
with the net cash proceeds of certain sales or other dispositions of assets.

    The Notes are fully and unconditionally guaranteed, jointly and severally,
on an unsecured, senior subordinated basis, by each of the Company's
subsidiaries (see Note 18). The Indenture permits the Company to incur
additional indebtedness (including Senior Indebtedness) of up to $45,000 as of
December 31, 1997, subject to certain limitations. The Indenture restricts the
Company's ability to pay dividends or make certain other restricted payments,
consummate certain asset sales, or otherwise dispose of all or substantially all
of the assets of the Company and its subsidiaries.

    The Company has also entered into a Credit Agreement providing for a
revolving credit facility (the "Credit Facility"). The Credit Facility enables
the Company to borrow up to $20,000. The revolving credit loans bear interest at
a rate based upon the lender's prime rate plus a borrowing margin of 1.5% or a
LIBOR-based rate plus a borrowing margin of 2.5%. The Company pays a commitment
fee of .5% based on the unused portion of the Credit Facility. The Credit
Facility terminates in March 2002. The Company had $19,191 of availability under
the Credit Facility as of December 31, 1997, net of outstanding letters of

MONITORING AND OVERSIGHT AGREEMENT

    Holding and the Company have entered into a ten-year monitoring and
oversight agreement with Hicks Muse. Pursuant thereto, Holding and the Company
have agreed to pay to Hicks Muse a minimum annual fee of $320 for ongoing
financial oversight and monitoring services to the Company. The annual fee is
adjustable upward or downward on January 1 of each calendar year to an amount
equal to 0.2% of the budgeted consolidated annual net sales of the Company and
its subsidiaries for the then-current fiscal year, provided that such fee shall
at no time be less than $320 per year. In the period ended October 2, 1998 and
the year ended December 31, 1997, $405 and $437 was paid to Hicks Muse under
this agreement, respectively. This agreement was terminated in connection with
the Recapitalization as defined in Note 19.

FINANCIAL ADVISORY AGREEMENT

    Holding and the Company are parties to a ten-year financial advisory
agreement (the "Financial Advisory Agreement") with Hicks Muse pursuant to which
Hicks Muse received a financial advisory fee of $2,000 on the closing date of

to the Company in connection with the Hicks Muse Transaction. Pursuant to the
Financial Advisory Agreement, Hicks Muse is also entitled to receive a fee equal
to 1.5% of the transaction value (as defined in the Financial Advisory

11. COMMITMENTS AND CONTINGENCIES: (CONTINUED)
    The Company has contracts with various suppliers to purchase aluminum for
use in the manufacturing process. The contracts vary from one to twelve months
and are at fixed quantities and fixed and floating prices. As of December 31,
1997 and 1996, the Company had forward commitments totaling $24,960 and $21,656
for delivery through December 1998 and 1997 for 28.6 and 28.7 million pounds of
aluminum, of which 14.3 and 10.0 million pounds were at fixed prices,
respectively.

    The Company has entered into employment agreements with several key
executives of the Company including its President and Chief Executive Officer,
its Chief Financial Officer and several Presidents, Vice Presidents, General
Managers and Sales Managers of the Company's divisions. The agreements generally
provide for terms of employment, annual salaries, bonuses, and eligibility for
option awards and severance benefits.

  CONTINGENCIES

    The Company is party to various claims, legal actions and complaints arising
in the ordinary course of business. In the opinion of management, all such
matters are without merit or are of such kind, or involve such amounts, that an
unfavorable disposition would not have a material effect on the financial
position, results of operations or liquidity of the Company.

    The Company is involved in various stages of investigation and cleanup
relative to environmental protection matters, some of which relate to waste
disposal sites. The potential costs related to such matters and the possible
impact thereof on future operations are uncertain due in part to: the
uncertainty as to the extent of pollution; the complexity of Government laws and
regulations and their interpretations; the varying costs and effectiveness of
alternative cleanup technologies and methods; the uncertain level of insurance
or other types of recovery; and the questionable level of the Company's
involvement. The Company was named in 1988 as a potentially responsible party
("PRP") in two superfund sites pursuant to the Comprehensive Environmental
Response Compensation and Liability Act of 1980, as amended (the Chemical
Recycling, Inc. site in Wylie, Texas, and the Diaz Refinery site in Little Rock,
Arkansas). The Company believes that based on the information currently
available, including the substantial number of other PRP's and relatively small
share allocated to it at such sites, its liability, if any, associated with
either of these sites will not have a material adverse effect on the Company's
financial position, results of operations or liquidity.

12. STOCK PURCHASE AGREEMENT:

  HICKS MUSE TRANSACTION

    The Hicks Muse Transaction refers to a recapitalization transaction that
closed concurrent with the closing of the issuance of the Notes in which
affiliates of Hicks Muse purchased a number of newly issued shares of Holding's
Common Stock for $32,000 pursuant to a Stock Purchase Agreement dated November
7, 1996, and certain outstanding shares, and certain options and warrants to
acquire shares of Holding's Common Stock and all outstanding shares of preferred
stock of Holding were redeemed.

    This transaction, which was completed on November 27, 1996, required
approximately $134,500 to complete, consisting of $59,417 in redemption payments
to the Selling Securityholders, $54,369 representing all outstanding
indebtedness under the Old Credit Facility and debt assumed in connection with
its acquisition of ADW--Northeast, $12,472 in redemption payments to preferred
stockholders of Holding

equity financing, (iii) drawings of $2,000 under the Company's Credit Facility,
and (iv) other cash provided by the Company of $500. The shares issued to Hicks
Muse, after giving effect to the other elements of the Hicks Muse Transaction,
represent approximately 82.0% of the outstanding common stock of Holding. The
Hicks Muse Transaction has been accounted for as a recapitalization.

13. SPECIAL CHARGES AND STOCK OPTION COMPENSATION EXPENSE

    Included in special charges in the 1996 Consolidated Statement of Income are
officer bonuses of $3,044 incurred in connection with the Hicks Muse
Transaction.

    Included in special charges in the 1998 Consolidated Statement of Loss are
officer bonuses of $3,885, transaction expenses of $2,780 and other costs of
$787 incurred in connection with the Recapitalization (see Note 19).

underlying common stock, the expense associated with the cash redemption of

ADW--Northeast, a manufacturer of vinyl replacement windows and doors for the
residential market in the northeast region of the United States, for $19,531. To
consummate the acquisition, the Company paid $13,531 to ADW-- Northeast's
shareholders (the "Sellers"), agreed to a $1,000 payable to the Sellers to be
paid if certain earnings targets are met, and issued $5,000 of Holding common
stock in exchange for all of ADW-- Northeast's capital stock. The $1,000 was
recorded as an accrued liability in the Company's financial statements at
December 31, 1996. During 1997, the Company paid $500 of the amount and adjusted
the purchase price by the remaining balance (this amount was recorded as a
reduction in goodwill). Holding subsequently contributed the ADW--Northeast
capital stock to the Company. Consequently, as of

16. STOCK OPTIONS:

    In connection with the Heritage Transaction, FCI Holding issued options (the
"Substitute Options") to certain members of Fojtasek management to purchase FCI
Holding's nonvoting common stock. The options vested ratably over five years or
immediately upon a public offering or a sale of substantially all the assets of
FCI Holding or a subsidiary. In connection with this issuance, $1,350 in
compensation expense representing the difference between the market value of the
underlying common stock and the exercise price of the option was deferred and
amortized over the vesting period. To effect the acquisition of ADW--Northeast,
FCI Holding formed Holding. The Substitute Option holders exchanged 2,875,922
options for equivalent nonvoting common stock options (the "Replacement
Options") in Holding's 1996 Original Stock Option Plan (the "Original Plan"). In
conjunction with the Hicks Muse Transaction, 2,875,922 options of Holding were
tendered at an exercise price of $.01, of which 1,050,000 were exchanged for
Replacement Options of Holding. In connection with the exchanged options, $1,040
was deferred and is being amortized over the new 5 year vesting period. Under
certain circumstances, if the option holders terminate employment prior to the
exercise of such option, they have the right to receive $1.00 per option (net of
the exercise price). Compensation expense of approximately $5,265, $1,384, $307
and $926 related to the options was recognized by the Company for the periods
ended October 2, 1998 and September 30, 1997 and for the years ended December
31, 1997 and 1996, respectively.

    FCI Holding also issued stock options (the "Disposition Options") to certain
members of Fojtasek management. Value was recognized on these options based on
the market value of the Company, which became exercisable upon a public offering
or a sale of substantially all the assets of FCI Holding or a subsidiary of FCI
Holding. In connection with the Hicks Muse Transaction, the options vested and
were redeemed and the resultant compensation expense of $743 was recorded in
stock option compensation expense in the 1996 Consolidated Statement of Income.

    Upon completion of the Hicks Muse Transaction, Holding adopted the 1996
Stock Option Plan (the "New Plan") authorizing the issuance of 3,500,000 options
to acquire common stock. Holding's New Plan gives certain individuals and key
employees of Holding and any subsidiary corporation thereof who are responsible
for the continued growth of Holding an opportunity to acquire a proprietary
interest in Holding and thus to create in such persons an increased interest in
and a greater concern for the welfare of Holding or any subsidiary. Through
December 31, 1997 and 1996, the Board of Directors of Holding has granted
2,185,390 and 1,910,390 options, respectively, under the New Plan at a weighted
average price of $1.00 per share which represented fair market value on the
dates of grant. The Company applies APB Opinion 25 and related interpretations
in accounting for the Plan.

    In connection with the Recapitalization (Note 19), options outstanding were
exchanged for options in the D&W Holdings Inc. Replacement Stock Option Plan.

    On November 27, 1996, Holding issued a warrant (the "Warrant") to the
President and Chief Executive Officer (the "Executive") of the Company. Pursuant
to the terms of the Warrant, the Executive is entitled to purchase 1,333,333
shares of Holding common stock at any time subsequent to the Hicks Muse
Transaction. The exercise price of the Warrant is $.01 per share. An additional
861,889 shares may be purchased under the Warrant at an exercise price of $1.00,
representing the fair market value on the date of grant upon the realization of
an 8.0% internal rate of return. The 861,889 options vest ratably each day for
three years. The Warrant will terminate on November 27, 2006. The Company
recorded non cash compensation expense of $1,320 for the period ended December
31, 1996 in connection with the difference between the fair market value of the
stock at the date of issuance ($1.00) and the exercise price ($.01).

    In 1995, the FASB issued FASB Statement No. 123 "Accounting for Stock-Based
Compensation" ("SFAS 123") which, if fully adopted by the Company, would change
the methods the Company applies in recognizing the cost of the stock-based
plans. Adoption of the cost recognition provisions of SFAS 123 is optional and
the Company has decided not to elect these provisions of SFAS 123. However, pro
forma disclosures as if the Company adopted the cost recognition provisions of
SFAS 123 in 1995 are required by SFAS 123 and are presented below. In 1998, 1997
and 1996, the Company granted only nonqualified stock options under the plans.

    The fair value of each stock option granted is estimated on the date of
grant using the minimum value method of option pricing with the following
weighted-average assumptions for grants in 1997 and 1996: dividend yield of
0.0%; risk-free interest rate of 7.0%; and the expected life of 10 years. (In
determining the "minimum value" SFAS 123 does not require the volatility of the
Company's common stock underlying the options to be calculated or considered
because the Company was not publicly-traded when the options were granted).

    Had the compensation cost for the Company's stock-based compensation plans
and warrants been determined consistent with SFAS 123, the Company's net income
(loss) for the period ended October 2, 1998 and the years ended December 31,
1997 and 1996 would have been $(4,880), $6,105 and $3,934, respectively.

    The effects of applying SFAS 123 in this pro forma disclosure are not
indicative of future amounts. SFAS 123 does not apply to awards prior to 1995,
and the Company anticipates making awards in the future under its stock-based
compensation plans.

17. EMPLOYEE BENEFIT PLANS:

  STOCK PURCHASE PLAN

    Holding's 1996 Stock Purchase Plan gives certain key employees of Holding or
related entities who are expected to contribute materially to the success of
Holding or related entities an opportunity to acquire a proprietary interest in
Holding, and thus to retain such persons and create in such persons an increased
interest in and a greater concern for the welfare of Holding and any Related
Entities. The Board of

Directors is authorized to offer 500,000 shares for purchase. As of December 31,
1997 and 1996, 425,000 and 375,000 shares, respectively, have been purchased
under the plan.

  401(K)

    During 1996, the Company established an employee benefit plan in accordance
with Section 401(k) of the Internal Revenue Code for all employees not covered
under a collective bargaining agreement. The Company may at its discretion match
employee contributions. During the period ended October 2, 1998 and the years
ended December 31, 1997 and 1996, the Company incurred no expense.

18. SUBSIDIARY GUARANTORS:

    In connection with the Note offering, the Company's payment obligations
under the Notes are fully and unconditionally guaranteed, jointly and severally
(collectively, the Subsidiary Guarantees) on a senior subordinated basis by its
wholly-owned subsidiaries: ADW--Northeast and ADW--West Coast (collectively, the
Subsidiary Guarantors). The Company has no non-guarantor direct or indirect
subsidiaries. The operations related to the assets of ADW--Northeast and
ADW--West Coast are included since September 30, 1996 and July 1, 1997,
respectively, the dates of acquisition. In the opinion of management, separate
financial statements of the respective Subsidiary Guarantors would not provide
additional material information, which would be useful in assessing the
financial composition of the Subsidiary Guarantors. No single Subsidiary
Guarantor has any significant legal restrictions on the ability of investors or
creditors to obtain access to its assets in event of default on the Subsidiary
Guarantee other than its subordination to senior indebtedness.

    Following is summarized combined financial information pertaining to these
Subsidiary Guarantors:

    On August 3, 1998, D and W ("Parent"), entered into an Agreement and Plan of
Merger (the "Merger Agreement") with Atrium Corporation ("Corp"), the parent
company of the Company and other necessary parties to acquire all of the
outstanding capital stock of Corp for $225.0 million, through a series of
transactions (the "Recapitalization") described below. Corp owned 100% of the
outstanding capital stock of the Company prior to the Merger discussed below. GE
Investment Private Placement Partners II, a limited partnership ("GEIPPPII"),
and Ardatrium L.L.C. ("Ardatrium") formed Parent by acquiring all of its
outstanding common stock for an aggregate purchase price of $50.0 million.
GEIPPPII is a private equity partnership affiliated with GE Investments, a
wholly-owned investment management subsidiary of General Electric Company.
Ardatrium is an affiliate of Ardshiel, Inc. ("Ardshiel"), a private equity
investment firm based in New York.

    The acquisition of Corp by Parent was effected through the merger on October
2, 1998 of a wholly owned subsidiary of Parent, with and into Corp (the
"Merger") pursuant to the terms of the Merger Agreement. Prior to the Merger,
Parent contributed $50.0 million to the wholly-owned subsidiary in exchange for
all of its outstanding common stock. As a result of the Merger, Corp became a
direct wholly-owned subsidiary of Parent, and the Company became an indirect
wholly owned subsidiary of Parent.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors of
Door Holdings, Inc.

    In our opinion, the accompanying combined balance sheets and the related
combined statements of income, stockholder's equity and of cash flows present
fairly, in all material respects, the financial position of R. G. Darby Company,
Inc. and Total Trim, Inc. (the "Companies") at December 31, 1997 and 1996, and
the results of their operations and their cash flows for the years ended
December 31, 1997 and 1996, in conformity with generally accepted accounting
principles. These combined financial statements are the responsibility of the
Companies' management: our responsibility is to express an opinion on these
combined financial statements based on our audits. We conducted our audits of
these statements in accordance with generally accepted auditing standards which
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, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

1.  ORGANIZATION:

    DESCRIPTION OF THE COMPANY AND REPORTING ENTITY

    R. G. Darby Company, Inc. ("R. G. Darby Company") and Total Trim, Inc.
("Total Trim") (the "Companies"), founded in 1983, provide interior and exterior
doors, vanity mirrors, door knobs and locks, shelving, molding, and related
installation to contractors of apartment buildings and hotels. The Companies are
based in Florence, Alabama and operate out of one facility. The Companies supply
materials and/ or provide contract labor to install purchased materials.
Material requirements, with the exception of doors, are shipped directly from
the manufacturer to the contractor's location. Doors are assembled and shipped
from the Companies' production facility. The Companies consist of three
entities--R. G. Darby Company is the sales company for materials; Darby Doors, a
division of R. G. Darby Company, is the manufacturing division that produces the
doors that are sold through R. G. Darby Company; and Total Trim is responsible
for contracting labor for any installation work. These entities perform work in
approximately 28 states, mainly in the South, Mid-Atlantic and Northeast.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

    PRINCIPLES OF COMBINATION

    The combined financial statements include the accounts of R. G. Darby
Company and Total Trim after elimination of all significant intercompany
accounts and transactions. Combined financial statements are presented as the
Companies are under the common control of their sole stockholder, R. G. Darby.
See Note 9.

    CASH AND CASH EQUIVALENTS

    The Companies consider all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents. The Companies hold
cash and cash equivalents primarily in one major banking institution.

    ALLOWANCE FOR DOUBTFUL ACCOUNTS

    Accounts receivable are net of allowances for doubtful accounts of $175 and
$66 as of December 31, 1997 and 1996, respectively.

    REVENUE RECOGNITION

    The Companies record sales of materials upon delivery of the materials to
the contractor's location. Revenue relating to the installation services is
recorded as the services are provided.

    INVENTORIES

    Inventories are stated at the lower of cost ( first-in, first-out or "FIFO")
or market and consist primarily of raw materials. Finished goods include direct
materials, labor and manufacturing overhead.

    PROPERTY AND EQUIPMENT

    Property and equipment are recorded at cost. Major renewals and betterments
are capitalized, while maintenance and repairs are expensed as incurred. Upon
disposition of an asset, the related cost and accumulated depreciation are
removed from the accounts and any gain or loss is included in income.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
Depreciation is provided principally on the straight-line method for financial
reporting purposes, using the following estimated useful lives of the respective
assets:

<TABLE>
<S>                                       <C>
Furniture and fixtures..................  7 - 10 years
Vehicles................................  3 -  5 years
Machinery and equipment.................  7 - 10 years
</TABLE>

    INCOME TAXES

    The combined financial statements reflect the Companies' S corporation
income tax status. Their taxable income or loss and tax credits are included in
the personal income tax returns of their stockholder and the resulting tax
liabilities or benefits are those of the stockholder.

    ACCOUNTING ESTIMATES

    The preparation of combined financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

Section 401 of the Internal Revenue Code. All employees are eligible to
participate in the Plan after six months of service and may enter the Plan after
such time on the annual enrollment date of January 1st. Under the Plan, the
Companies will contribute to the Plan an amount determined at their discretion
and may choose not to contribute to the Plan for a particular plan year. The
Plan does not permit employees to make contributions. The Companies'
contribution to the Plan was approximately $58 for each of the years ended
December 31, 1997 and 1996, respectively.

9.  SUBSEQUENT EVENTS:

    Effective January 8, 1998, the Companies were sold to Door Holdings, Inc.
("Door"). As specified in the agreement, the sales price was $24,000 plus or
minus any adjustment resulting from the Companies' combined working capital, as
defined in the sale agreement, being above or below $2,323 as of the closing
date. Included in the $24,000 is a contingent payment of $4,000 to be paid to
the former stockholder based on future operating results. An additional $2,000
payment, which has not been recorded in the purchase price, may be paid to the
Seller if these financial targets are substantially exceeded. The purchase price
was funded primarily with $5,700 equity contributions, $16,000 of long-term
debt, and accrual of the deferred payment. Door did not have any significant
activity prior to this transaction.

    Pursuant to the terms of an Agreement and Plan of Merger (the "Merger
Agreement"), dated as of August 3, 1998, Door will become a wholly-owned
subsidiary of Atrium Companies, Inc. and an indirect wholly owned subsidiary of
D and W Holdings, Inc. ("D&W") (the "Merger"). D&W was formed to effect the
Merger by the principal equity holders of Door and Wing Industries Holdings,
Inc., an affiliate of Door. Pursuant to the terms of the Merger Agreement, D&W
is also acquiring Atrium Companies, Inc. Transactions contemplated pursuant to
the Merger Agreement are expected to be consummated no later than September 30,
1998.

1. BASIS OF PRESENTATION:

    The unaudited consolidated results of operations and cash flow of Door
Holdings, Inc. (formerly known as R.G. Darby Company, Inc. and Total Trim, Inc.
See Note 2.) for the nine months ended September 30, 1998 and 1997, and
financial position as of September 30, 1998 have been prepared in accordance
with generally accepted accounting principles for interim financial reporting.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.

    These consolidated financial statements and footnotes should be read in
conjunction with the audited combined financial statements of R.G. Darby
Company, Inc. and Total Trim, Inc. for the years ended December 31, 1997 and
1996 included herein. In the opinion of management, all adjustments (consisting
of normal recurring adjustments) considered necessary for a fair presentation of
the interim financial information have been included. The results of operations
for any interim period are not necessarily indicative of the results of
operations for a full year.

2. BASIS OF ACCOUNTING AND CHANGE IN OWNERSHIP:

    R.G. Darby Company, Inc. ("R.G. Darby Company") and Total Trim, Inc. ("Total
Trim") (the "Companies") (the "Predecessor"), founded in 1983, provide interior
and exterior doors, vanity mirrors, door knobs and locks, shelving, molding, and
related installation to contractors of apartment buildings and hotels. The
Companies are based in Florence, Alabama and operate out of one facility. The
Companies supply materials and/or provide contract labor to install purchased
materials. Material requirements, with the exception of doors, are shipped
directly from the manufacturer to the contractor's location. Doors are assembled
and shipped from the Companies' production facility. The Companies consist of
three entities-- R.G. Darby Company is the sales company for materials; Darby
Doors, a division of R.G. Darby Company, is the manufacturing division that
produces the doors that are sold through R.G. Darby Company; and Total Trim is
responsible for contracting labor for any installation work. These entities
perform work in approximately 28 states, mainly in the South, Mid-Atlantic and
Northeast.

    Effective January 8, 1998, the Companies were sold to Door Holdings, Inc.
("Door"). As specified in the agreement, the sales price was $24,000 plus or
minus any adjustments resulting from the Companies' combined working capital, as
defined in the sale agreement, being above or below $2,323 as of the closing
date. Included in the $24,000 is a contingent payment of $4,000 to be paid to
the former stockholder based on future operating results. An additional $2,000
which has not been recorded in the purchase price may be paid to the seller if
these financial targets are substantially exceeded. The purchase price was
funded primarily with $5,700 equity contributions, $16,000 of long-term debt,
and accrual of the deferred payment. Door did not have any significant activity
prior to this transaction. For the purpose of financial statement presentation,
the change in ownership occurring on January 8, 1998 was considered effective
January 1, 1998.

    The Acquisition has been accounted for under the purchase method of
accounting. The aggregate purchase price of $24,520, (which includes $520 of
transaction related expenses) has been allocated to the underlying assets and
liabilities based upon their respective estimated fair market values at the date
of

acquisition, with the remainder allocated to goodwill, being amortized on a
straight line basis over forty years. The preliminary purchase price allocation
is as follows:

</TABLE>

    The financial statements for the nine months ended September 30, 1997 were
prepared for the Companies on their predecessor basis. No tax provision was
recorded for the nine months ended September 30, 1997 as the Companies were S
corporations for income tax purposes. The financial statements for the nine
months ended September 30, 1998 reflect the purchase adjustments discussed
above. Door is a C corporation for income tax purposes and therefore an income
tax provision has been recorded for the 1998 period. The primary differences
between the 1998 presentation and the 1997 presentation are the additional
amortization expense, interest expense, and income tax expense reflected in 1998
due to the purchase transaction discussed above.

3.  INVENTORIES:

    Inventories, which are valued at the lower of cost or market using the
first-in, first-out (FIFO) method of accounting consisted of the following at

4.  NOTES PAYABLE:

    In connection with the acquisition discussed in Note 2 above, Door entered
into a $6,000 subordinated note payable to GE Investment Private Placement
Partners II ("GEIPPPII"), payable interest only in quarterly installments at
11.5% on the unpaid face amount, due January 9, 2004. The valuation assigned to
common stock warrants of 11,712 issued in conjunction with this note resulted in
a discount of $769 and an effective interest of approximately 16.78%. The
unamortized discount at September 30, 1998 was $687.

    Also, in connection with the acquisition discussed in Note 2 above, Door
entered into a Credit Agreement providing for a $5,000 revolving credit facility
(the "Revolving Credit Facility") and a $10,000 Senior secured term loan
facility (the "Term Loan"). The Revolving Credit Facility and the Term Loan bear
interest at a rate based upon the lender's prime rate plus a borrowing margin of
1.5% or a EURO-based rate plus a borrowing margin of 2.5%. Door pays a
commitment fee of .375% based on the unused portion of both credit facilities.
The Revolving Credit Facility terminates on January 7, 2003. Door had

$5,000 of availability under the Revolving Credit Facility as of September 30,
1998. In connection with the acquisition discussed in Note 2 above, Door
borrowed $10,000 under the Term Loan. Principal payments on the Term Loan are
due quarterly at amounts ranging from $250 to $400 through December 31, 2004.
Outstanding borrowings on the Term Loan at September 30, 1998 were $9,500 at an
approximate interest rate of 8.0%. The Credit Agreement contains various
covenants that restrict Door from taking various actions and requires Door to
achieve and maintain certain financial covenants. All tangible and intangible
assets of Door collateralize these credit facilities.

    Principal payments due during the next fiscal five years on notes payable as
of September 30, 1998 are as follows:

5.  CONTINGENCIES:

    Door is party to various claims, legal actions, and complaints arising in
the ordinary course of business. In the opinion of management, all such matters
are without merit or are of such kind, or involve such amounts, that an
unfavorable disposition would not have a material adverse effect on the
consolidated financial position, results of operations or liquidity of Door.

6.  COMMON STOCK PLAN:

    Effective January 9, 1998, the Board of Directors of Door approved the Door
Stock Option Plan (the Plan) that provides for the grant of incentive stock
options and nonqualified stock options to certain employees, officers and
directors of Door and its affiliates, as defined in the Plan. Under the Plan,
10,000 shares of Door's common stock have been reserved for issuance. Incentive
stock options granted under the Plan provide for the purchase of Door's common
stock at not less than fair value on the date the option is granted. However,
incentive stock options granted to any employee owning stock possessing more
than 10% of the total combined voting power of all classes of stock of Door
shall be at least 110% of the fair market value of Door's common stock on the
date the option is granted. Nonqualified stock options granted under the Plan
provide for the purchase of Door's common stock at a price specified by the
Stock Option Committee, which may be less than, equal to, or greater than the
fair market value of the common stock on the date such option is granted.

    As of September 30, 1998, incentive stock options for approximately 5,900
shares of common stock were granted at approximately $117 per share. The option
price of $117 per share will increase annually by 15% for 2,000 shares and 30%
for 3,900 shares as defined by the Plan. These options become exercisable

6.  COMMON STOCK PLAN: (CONTINUED)
over a three-year period and expire in January 2008. In addition, nonqualified
stock options for approximately 1,600 shares of common stock were granted at
approximately $235 per share. These options become exercisable upon the
happening of a "Value Event" as described in the Plan and expire in January
2008. As of September 30, 1998, there has been no Value Event.

7.  RELATED PARTIES:

    On January 9, 1998, Door entered into a ten-year Management and Investment
Banking Agreement (the "Management Agreement") with Ardshiel, Inc., ("Ardshiel")
a related party of Arddoor, L.L.C., an equityholder of Door Holdings, Inc.
Pursuant thereto, Door has agreed to pay Ardshiel an annual fee of $200 plus
expenses for on-going management advisory services to Door. The management
agreement also gives Ardshiel the first opportunity, in most instances, to
perform investment banking services for Door, for a fee equal to 2% of the total
transaction price related to any such sale/acquisition under the services
provided. The agreement is terminated in the event Ardshiel and Arddoor, L.L.C.
cease to be affiliates of Door.

8.  SUBSEQUENT EVENTS:

    Pursuant to the terms of an Agreement and Plan of Merger (the "Merger
Agreement"), dated as of August 3, 1998, Door became a wholly-owned subsidiary
of Atrium Companies, Inc. and an indirect wholly owned subsidiary of D and W
Holdings, Inc. ("D&W") (the "Merger"). D&W was formed to effect the Merger by
the principal equity holders of Door and Wing Industries Holdings, Inc., an
affiliate. Pursuant to the terms of the Merger Agreement, D&W is also acquiring
Atrium Companies, Inc. Transactions contemplated pursuant to the Merger
Agreement were consummated October 2, 1998.

    Immediately prior to the merger, the subordinated note payable and related
warrants were converted into common stock of Door.

    In connection with the Merger, management exchanged all options in Door for
options to purchase stock in D&W. It is expected that the management agreement
will be terminated and replaced by a new agreement with D&W upon consummation
with the Merger.

    As a part of the Merger, the notes payable remaining after conversion were
repaid and the deferred financing cost was expensed.

1. ORGANIZATION, BUSINESS AND BASIS OF PRESENTATION:

    Heat, Inc. (the "Company"), a Delaware corporation, was incorporated on
January 2, 1997 by HIG Capital Management and affiliated companies ("HIG") for
the purpose of acquiring and owning Thermal Industries, Inc. ("Thermal"), based
in Pittsburgh, Pennsylvania, and Best Built, Inc. ("Best Built"), based in Union
Gap, Washington. The acquisitions were consummated effective May 30, 1997. The
statements of operations for the period from January 1, 1997 to May 30, 1997 and
the year ended December 31, 1996 only include the operations of Thermal as
Thermal was deemed to be the predecessor company. The Company is engaged in the
manufacture of vinyl-framed, made-to-order windows, replacement sliding doors,
patio enclosures, vinyl porch decks and boat docks. The products are primarily
sold to remodeling or home improvement contractors for use in residential
remodeling through the Company's twenty-one branch locations. In addition,
products are also sold to wholesale distributors for use in new construction.

    The purchase price of the acquisitions exceeded the fair value of the net
assets acquired by approximately $17,273. Pursuant to the terms of the Best
Built purchase agreement, the Company made an additional payment of $830 during
1998. In addition, in January 1999, the Company reached a settlement with
shareholders dissenting to the merger. The settlement amount exceeded the
previously recorded liability by approximately $673. Refer to Note 9 for further
discussion.

2. SIGNIFICANT ACCOUNTING POLICIES:

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the dates of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. Actual results may differ from previously estimated amounts.

    The consolidated financial information as of March 31, 1999 and for the
three months ended March 31, 1998 and 1999 is unaudited. In the opinion of
management, the accompanying unaudited consolidated financial information and
related notes thereto contain all adjustments consisting only of normal
recurring adjustments, necessary to present fairly the consolidated financial
information as of March 31, 1999 and the operating results and cash flows for
the three months ended March 31, 1999 and 1998. Certain information and footnote
disclosures normally included in financial statements prepared in accordance
with generally accepted accounting principles have been omitted pursuant to the
rules and regulations of the Securities and Exchange Commission. The results of
operations for the periods presented are not necessarily indicative of the
results to be expected for the full year.

  BASIS OF CONSOLIDATION

    The accounts of the Company and its wholly-owned subsidiaries are included
in the consolidated financial statements. All significant intercompany accounts
and transactions have been eliminated in consolidation. The reference to the
periods ended December 31, 1997 and May 30, 1997 used throughout these
consolidated financial statements, refer to the periods May 31, 1997 through
December 31, 1997 and January 1, 1997 through May 30, 1997, respectively.

2. SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
  INDUSTRY SEGMENT

    The Company operates in a single industry segment, the fabrication and
distribution windows and related components.

  REVENUE RECOGNITION

    The Company manufactures the products noted above and provides separate
installation services for customers that request such services under sales
contracts that may require cash deposits. The Company records the sale of
products upon transfer of title to the customer, which typically occurs upon
shipment, and records revenue from installation projects when the projects are
complete.

  CASH AND CASH EQUIVALENTS

    The Company considers all highly liquid investments with a maturity of
ninety days or less when purchased to be cash equivalents.

  ADVERTISING COSTS

    Advertising costs are expensed when incurred and were $185, $68, $61, and
$80 for the year ended December 98, the periods ended December 31, 1997 and May
30, 1997, and the year ended December 31, 1996, respectively.

  CONCENTRATIONS OF CREDIT RISK

    Financial instruments, which potentially expose the Company to
concentrations of credit risk, consist primarily of trade accounts receivable.
The Company's customers are located in various regions of the United States. The
Company performs ongoing credit evaluations of its customers' financial
condition and generally requires no collateral. The Company establishes an
allowance for doubtful accounts based upon factors surrounding the credit risk
of specific customers, historical trends and other information. No customers
accounted for approximately 10% of gross sales for the year ended December 31,
1998, the periods ended December 31, 1997 and May 30, 1997 and the year ended
December 31, 1996.

  INVENTORIES

    Inventories are carried at the lower of first-in, first-out (FIFO) cost or
market and consist of the following:

  PROPERTY, PLANT AND EQUIPMENT

    Property, plant and equipment are stated at cost. Additions and improvements
of significant items are capitalized while expenditures for maintenance and
repairs are charged to operations as incurred. Provisions for depreciation are
computed principally by the straight-line method based upon the estimated useful
lives of the assets. Property, plant and equipment balances and useful lives are
as follows:

    Depreciation expense for the year ended December 31, 1998, the periods ended
December 31, 1997 and May 30, 1997, and the year ended December 31, 1996 was
$1,321, $662, $703 and $1,782, respectively.

  NONCOMPETE AND CONSULTING AGREEMENTS

    In connection with the acquisition of Best Built, the seller agreed not to
compete with the Company for a period of five years in exchange for an initial
payment of $150 and an additional payment of $125 during 1998. The cost of this
agreement is being amortized using the straight-line method over its five-year
contractual life. Additionally, the seller is being retained as a consultant for
the Company through May 29, 1999, subject to extension upon mutual agreement of
the Company and the seller.

  GOODWILL

    Goodwill is being amortized over forty years on a straight-line basis.
Accumulated amortization was approximately $628 and $229 at December 31, 1998
and 1997, respectively. It is the Company's policy to review goodwill (and other
intangible assets) for possible impairment on the basis of whether the carrying
amount of such assets is fully recoverable from projected undiscounted net cash
flows from the related business. If such review indicates that the carrying
amount of goodwill and other intangible assets is not recoverable, then the
Company's policy is to reduce the carrying amount of such assets to fair value.

  FAIR VALUE OF FINANCIAL INSTRUMENTS

    In accordance with Statement of Financial Accounting Standards (SFAS) No.
107, DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS, the following
methods have been used in estimating fair value disclosures for significant
financial instruments of the Company.

    Estimated fair value amounts have been determined by the Company using
available market information and appropriate valuation methodologies. Since
considerable judgment is required to interpret market data to develop the
estimates of fair value, the estimates presented are not necessarily indicative
of the amounts that could be realized in a current market exchange.

    Cash and cash equivalents, accounts receivable, accounts payable, and other
    current liabilities--The carrying amounts reported in the balance sheet for
    these accounts approximate the fair value due to their short maturities.

    Long-term debt--The fair value of the Company's debt approximates the
    carrying value since interest rates are variable for the maturity of the
    debt. Management believes the fixed rate debt is consistent with other
    financial instruments of similar rating and risk.

  TREASURY STOCK

    Treasury stock represents stock held principally for sale and issuance to
employees. Purchases of treasury stock are recorded at cost. Sales of treasury
stock are valued using the weighted average method. All treasury stock was
eliminated as part of the acquisition of Thermal and Best Built by the Company.

7. STOCK OPTION PLANS:

    In October 1984, Thermal adopted an incentive stock option plan (the "Old
Plan") for its key employees. Options granted under the Old Plan were granted
with an exercise price that equaled or exceeded fair market value of Thermal's
common stock at the date of grant.

    Ten years from the date the Old Plan was adopted, the Old Plan was
terminated. However, all rights created under options granted continued until
such options were excercised or expired. In connection with acquisition of
Thermal and Best Built by the Company, all options under the Old Plan were
exercised.

    On May 30, 1997, the Company adopted a stock option plan pursuant to the
Heat, Inc. 1997 Stock Purchase and Option Plan (the "Plan") for its key
employees, directors, consultants and advisers. The option plan provides for the
grant of up to 250,000 shares of common stock. Under the Plan, certain employees
have received incentive options under the Internal Revenue Service Code Section
422, while others have received nonqualified stock options in accordance with
the Plan.

    Generally, all options issued under the Plan vest equally in 25% annual
increments over the four-year period subsequent to the grant date. All options
become fully vested upon a sale of the Company and must be exercised in
connection with the sale of the Company or they shall be forfeited. Options were
granted with an exercise price that equalled or exceed fair value of the
Company's common stock. Options for 22,500 shares were granted at the time of
acquisition, which vest between 1998 and 2005 based upon the Company's future
operating results. The outstanding stock options under the Plan have an average
remaining contractual life of ten years at December 31, 1998.

    Stock option transactions are summarized as follows:

    In October 1995, the Financial Accounting Standards Board issued STATEMENT
OF FINANCIAL ACCOUNTING STANDARD ("SFAS") No. 123, ACCOUNTING FOR STOCK-BASED
COMPENSATION. SFAS No. 123 encourages a fair-value based method of accounting
for employee stock options and similar equity instruments. SFAS No. 123 also
allows an entity to continue to account for stock-based employee compensation
using the intrinsic value for equity instruments using APB Opinion No. 25. As
provided for in SFAS No. 123, the Company elected to continue the intrinsic
value method of expense recognition. Accordingly, no compensation cost has been
recognized for the stock option plans. Had compensation expense for the stock
option plans been determined consistent with the provisions of SFAS No. 123, the
Company's net income for the year ended December 31, 1998, the periods ended
December 31, 1997 and May , 1997 and the year ended December , 1996 would not
have been materially different.

    In connection with acquisition transactions discussed in Note 1, the Company
also sold 45,000 shares (Class A) to certain employees, at the fair market value
as determined by management and based on the value of the merger transaction.
These shares and any shares issued under the stock option plan, as described
above, are subject to certain terms and conditions including, among others,
restrictions on transfer, repurchase rights and a put feature.

    In connection with the sale of the Company (see Note ), all options
outstanding under the Plan were exercised and the Plan was terminated.

8. RELATED PARTY TRANSACTIONS:

    In connection with the merger, the Company agreed to pay a management fee to

    The Company is currently a defendant in a lawsuit claiming that the Company
is liable and negligent in the design and manufacture of windows installed in a
large condominium project. The case is currently in mediation with a scheduled
trial date of May 1999. Management is of the opinion that the ultimate
resolution of this matter, after considering its insurance coverage and based on
discussions with outside legal counsel, will not have a material adverse effect
on the Company's financial condition or its results of operation.

    The Company is involved in various other claims and litigation incidental to
the conduct of its business. Based on consultation with legal counsel,
management does not believe that any claims or litigation to which the Company
is a party will have a material adverse effect on the Company" financial
condition or results of operations.

the period ended May , 1997 are transportation expenses (primarily consisting of

    The purchase price of $30,122 was financed with net debt proceeds of

13. SUBSEQUENT EVENT:

    In connection with the acquisition of Thermal by the Company, certain
shareholders of Thermal exercised their rights to dissent from the merger and to
demand payment of the fair value of their shares. Pursuant to the terms of the
merger, each share of Thermal stock was converted into the right to receive a
cash payment per share, based on the price per share accepted by the
nondissenting shareholders. The dissenting shareholders asserted that they have
certain rights to seek appraisals of the fair value of their shares. In the
aggregate, the dissenting shareholders were the beneficial owners of 144,186
shares of Thermal. On January 22, 1999, the Company entered into a Settlement
and Release Agreement with the dissenting shareholders to pay $2,840 in exchange
for all their shares held. A liability for $2,167 reflecting the anticipated
settlement amount had been previously recorded in the accompanying consolidated
balance sheet at December 31, 1997. As a result of the final settlement of this
matter, the liability was increased to $2,840 and was paid out in January 1999.
This additional amount was reflected as an increase to goodwill.

    In connection with the Best Built acquisition, the Company paid the seller
an additional $830 in 1998 as a result of Best Built achieving a defined gross
profit level for the 12-month period ended May 31, 1998. This additional amount
was reflected as an increase to goodwill.

    On April 20, 1999, the Company was acquired by Atrium Companies, Inc., a
company engaged in the manufacture and sales of doors, windows, and various
building materials throughout the United States, for approximately $85,000.
