ITEM 1.  SECURITY AND SUBJECT COMPANY.
 
     The name of the subject company is American Buildings Company, a Delaware
corporation (the "Company"). The address of the principal executive offices of
the Company is 1150 State Docks Road, Eufaula, Alabama 36027. The title of the
class of equity securities to which this Solicitation/Recommendation Statement
on Schedule 14D-9 (this "Statement" or this "Schedule 14D-9") relates is the
common stock, par value $.01 per share (the "Common Stock"), of the Company.
 
ITEM 2.  TENDER OFFER OF THE BIDDER.
 
     This statement relates to the tender offer (the "Offer") by ABCO
Acquisition Corp., a Delaware corporation ("Purchaser"), a wholly owned
subsidiary of ABCO Holdings Corp., a Delaware corporation ("Parent") and an
indirect wholly-owned subsidiary of Onex Corporation, an Ontario corporation
("Onex"), as set forth in the Tender Offer Statement on Schedule 14D-1 dated
April 13, 1999 (as amended or supplemented, the "Schedule 14D-1"), to purchase
all outstanding shares of Common Stock (the "Shares") at $36 per Share, net to
the seller in cash, without interest thereon, upon the terms and subject to the
conditions set forth in the Offer to Purchase dated April 13, 1999 (the "Offer
to Purchase") and the related Letter of Transmittal (which, together with the
Offer to Purchase, as each may be amended and supplemented from time to time,
collectively constitute the "Offer Documents").
 
     The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of April 7, 1999 (the "Merger Agreement"), by and among Parent, Purchaser and
the Company. Pursuant to the Merger Agreement, following the consummation of the
Offer, upon the satisfaction or waiver of certain conditions, the Purchaser will
be merged with and into the Company (the "Merger"), with the Company continuing
as the surviving corporation (the "Surviving Corporation"). A copy of the Merger
Agreement is filed as Exhibit 1 hereto and is incorporated herein by reference.
The Merger Agreement is summarized in Item 3 hereof.
 
     As set forth in the Schedule 14D-1, the address of the principal executive
offices of Parent and Purchaser is c/o Onex Investment Corporation, 712 Fifth
Avenue, 40th Floor, New York, New York 10019, and the address of Onex is Canada
Trust Tower, 161 Bay Street, 49th Floor, Toronto, Ontario M5J 2S1 Canada. Parent
and Purchaser are subsidiaries of Onex.
 
ITEM 3.  IDENTITY AND BACKGROUND.
 
     (a) The name and address of the Company, which is the person filing this
Statement, are set forth in Item 1 above.
 
     (b) Except as described herein or in Annex A hereto, which is incorporated
herein by reference, as of the date hereof, there are no material contracts,
agreements, arrangements or understandings, or any actual or potential conflicts
of interest between the Company or its affiliates and (i) the Company, its
executive officers, directors or affiliates or (ii) Parent, Purchaser or Onex or
their respective executive officers, directors or affiliates.
 
ARRANGEMENTS WITH DIRECTORS, EXECUTIVE OFFICERS OR AFFILIATES OF THE COMPANY
 
     Certain contracts, agreements, arrangements and understandings between the
Company or its affiliates and certain of its directors, executive officers and
affiliates are described under the captions "Board of Directors and Executive
Officers," "Security Ownership of Certain Beneficial Owners and Management" and
"Executive Compensation" in the Company's Information Statement (the
"Information Statement"), which is attached hereto as Annex A and is
incorporated herein by reference.
 
     The employment agreements between the Company and each of its executive
officers provide that if such officer's employment is terminated by the Company
at any time within one year following a change of control of the Company for any
reason other than justifiable cause, disability or death, the Company must pay
such officer a lump sum payment equal to two years' annual salary plus an amount
equal to twice the executive's most recently declared bonus. The consummation of
the Offer would constitute a change of control of the Company for purposes of
the employment agreements.
                                        2
<PAGE>   3
 
     The Company's outstanding options to purchase Shares provide that they
become immediately exercisable upon a change of control of the Company. The
consummation of the Offer would constitute a change of control of the Company
for purposes of the options.
 
     Pursuant to the Company's Shareholder Value Added Plan, all amounts
allocated to such plan's award bank become vested and payable upon a change of
control of the Company. There is currently approximately $311,000 in the award
bank held for the benefit of key senior and middle management executives. The
consummation of the Offer would constitute a change of control of the Company
under the Shareholder Value Added Plan.
 
     On March 30, 1999, the Company's Board of Directors approved an amendment
to the Company's management agreement with Sterling Ventures Limited
("Sterling") to provide that the management fee due under the agreement for the
remaining term of the agreement would be paid upon the occurrence of a change of
control of the Company. Mr. Douglas L. Newhouse, a director of the Company, and
Mr. William L. Selden, Chairman of the Board of Directors of the Company, who
collectively own 66.67% of Sterling, abstained from voting on this matter. The
consummation of the Offer would constitute a change of control of the Company
under the management agreement.
 
ARRANGEMENTS WITH PARENT, PURCHASER OR THEIR AFFILIATES
 
     In connection with the transactions contemplated by the Offer and the
Merger, the following agreements and arrangements were entered into: (i) the
Merger Agreement, (ii) the letter of undertaking, dated April 7, 1999, from Onex
to the Company (the "Letter of Undertaking") and (iii) the Confidentiality
Agreement, dated as of March 8, 1999, between the Company and Onex (the
"Confidentiality Agreement").
 
  The Merger Agreement
 
     The following is a summary of certain material provisions of the Merger
Agreement. This summary does not purport to be complete and is qualified in its
entirety by reference to the complete text of the Merger Agreement, a copy of
which is filed as Exhibit 1 hereto and is incorporated herein by reference.
Capitalized terms not otherwise defined below shall have the meanings set forth
in the Merger Agreement.
 
     The Offer.  The Merger Agreement provides that Purchaser will commence the
Offer and that, upon the terms and subject to the prior satisfaction or waiver
of the conditions of the Offer, Purchaser will purchase all Shares validly
tendered and not withdrawn pursuant to the Offer. The Merger Agreement provides
that, without the written consent of the Company, Purchaser will not (i) waive
the condition that there be validly tendered and not withdrawn prior to the
expiration of the Offer that number of Shares which, together with the Shares
then owned by Purchaser and its affiliates, would constitute a majority of the
outstanding Shares on a fully-diluted basis (the "Minimum Condition"), (ii)
reduce the number of Shares to be purchased in the Offer, (iii) reduce the Offer
Price, (iv) modify or add to the conditions to the Offer set forth in Exhibit A
to the Merger Agreement and described below, (v) except as set forth in the
following two sentences, extend the Offer, (vi) change the form of consideration
payable in the Offer or (vii) amend any other term of the Offer in a manner
adverse to the holders of the Shares. However, if on the initially scheduled
expiration date (the initially scheduled expiration date being 20 Business Days
following commencement of the Offer) any of the conditions to the Offer has not
have been satisfied or waived, Purchaser may, without the consent of the
Company, extend the expiration date on one or more occasions for up to 10
Business Days for each extension or for any period required by any rule,
regulation, interpretation or position of the Securities and Exchange Commission
(the "Commission") or its staff applicable to the Offer. In addition, if
immediately prior to the expiration date, as it may be extended, all of the
conditions to Purchaser's obligations to accept for payment, and to pay for, the
Shares are satisfied or waived, but the Shares tendered and not withdrawn
pursuant to the Offer (together with the Shares then owned by Purchaser and its
affiliates) are less than 90% of the outstanding Shares, Purchaser may extend
the Offer for a period of not more than 10 Business Days.
 
     Conditions of the Offer.  Notwithstanding any other term of the Offer or
the Merger Agreement, Purchaser is not required to accept for payment or,
subject to any applicable rules and regulations of the Commission, including
Rule 14e-1(c) under the Securities Exchange Act of 1934, as amended (the
                                        3
<PAGE>   4
 
"Exchange Act") (relating to Purchaser's obligation to pay for or return
tendered Shares after the termination or withdrawal of the Offer), to pay for
any Shares tendered pursuant to the Offer unless (i) the Minimum Condition is
satisfied and (ii) any waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"), applicable to the purchase
of Shares pursuant to the Offer shall have expired or been terminated.
Furthermore, notwithstanding any other term of the Offer or the Merger
Agreement, Purchaser is not required to accept for payment or, subject as
aforesaid, to pay for any Shares not theretofore accepted for payment or paid
for, and may terminate the Offer if, at any time on or after the date of the
Merger Agreement and before the acceptance of such Shares for payment or the
payment therefor, any of the following conditions exists (other than as a result
of any action or inaction of Parent, Purchaser or any subsidiary of Parent which
constitutes a breach of the Merger Agreement):
 
          (a) there shall be threatened (with a reasonable likelihood of being
     brought) or pending by any governmental entity or by any other person any
     suit, action or proceeding (i) challenging or seeking to make illegal the
     acquisition by Parent or Purchaser of any Shares under the Offer, seeking
     to restrain or prohibit the making or consummation of the Offer or the
     Merger or seeking to obtain from the Company, Parent or Purchaser any
     damages that are material in relation to the Company and its subsidiaries
     taken as whole or seeking to impose any material adverse conditions in
     connection therewith, (ii) seeking to prohibit or limit the ownership or
     operation by the Company or any of its subsidiaries or Parent or Purchaser
     of a material portion of any material business or material assets of the
     Company and its subsidiaries, taken as a whole, or to compel the Company or
     Parent to dispose of or hold separate any material portion of any material
     business or material assets of the Company and its subsidiaries, taken as a
     whole, as a result of the Offer or the Merger, (iii) seeking to impose
     limitations on the ability of Parent or Purchaser to acquire or hold, or
     exercise full rights of ownership of, any Shares accepted for payment
     pursuant to the Offer including, without limitation, the right to vote such
     Shares on all matters properly presented to the stockholders of the
     Company, or (iv) seeking to prohibit Parent or Purchaser from effectively
     controlling in any material respect the business or operations of the
     Company and its subsidiaries, taken as a whole;
 
          (b) there shall be any statute, rule, regulation, judgment, order or
     injunction enacted, entered, enforced, promulgated or deemed applicable to
     the Offer or the Merger, or any other action shall be taken by any
     governmental entity, other than the application to the Offer or the Merger
     of applicable waiting periods under the HSR Act, that is reasonably likely
     to result, directly or indirectly, in any of the consequences referred to
     in clauses (i) through (iv) of paragraph (a) above;
 
          (c) there shall have occurred any events after April 7, 1999 which,
     individually or in the aggregate, have or are reasonably likely to have a
     Material Adverse Effect on the Company;
 
          (d) (i) the Company or the Board or any committee thereof shall have
     taken any action pursuant to Section 6.02(b) of the Merger Agreement or
     approved or recommended any Acquisition Proposal (as hereinafter defined)
     or (ii) the Company shall have entered into any definitive agreement for a
     Superior Proposal (as hereinafter defined);
 
          (e) the representations and warranties of the Company set forth in the
     Merger Agreement (disregarding any qualification as to, or exception based
     on, materiality or Material Adverse Effect) shall not be true and correct
     (except for failures to be true and correct which would not, individually
     or in the aggregate, have a Material Adverse Effect) as of the date of the
     Merger Agreement and as if such representations and warranties were made at
     any time prior to the purchase of Shares pursuant to the Offer as if made
     at and as of such time;
 
          (f) the Company shall have (i) knowingly breached or failed to perform
     in any material respect any material obligation or to comply in any
     material respect with any material agreement or covenant of the Company to
     be performed or complied with by it under the Merger Agreement which is not
     cured within five days after notice from Purchaser or (ii) breached or
     failed to perform any obligation or to comply with any agreement or
     covenant of the Company to be performed or complied with by it under the
     Merger Agreement, which breach or failure in the case of this clause (ii)
     (x) has or is reasonably likely
 
                                        4
<PAGE>   5
 
     to have a Material Adverse Effect or (y) prevents the purchase of Shares
     pursuant to the Offer or the Merger;
 
          (g) the Merger Agreement shall have been terminated in accordance with
     its terms; or
 
          (h) there shall have occurred and be continuing (i) any general
     suspension of trading in securities on the New York, Toronto, or American
     Stock exchanges or in the Nasdaq National Market System (other than circuit
     breakers), (ii) the declaration of a banking moratorium or any suspension
     of payments in respect of banks in the United States or Canada, (iii) the
     commencement of a war, armed hostilities or other international or national
     calamity or emergency, directly or indirectly involving the United States
     or Canada (with the exception of any such occurrence involving Iraq or
     Yugoslavia), (iv) any limitations (whether or not mandatory) imposed by any
     governmental entity on the nature or extension of credit or further
     extension of credit by banks or other lending institutions or (v) a
     currency moratorium on the exchange markets in Canada or the United States
     with respect to the Canadian or United States dollar;
 
which, in the judgment of Purchaser in any case and regardless of circumstances,
makes it inadvisable to proceed with such acceptance for payment or payment.
 
     The foregoing conditions are for the sole benefit of Purchaser and Parent
and may, subject to the terms of the Merger Agreement, be waived by Purchaser
and Parent in whole or in part at any time and from time to time in their sole
discretion. The failure by Parent or Purchaser at any time to exercise any of
the foregoing rights shall not be deemed a waiver of any such right, the waiver
of any such right with respect to particular facts and circumstances shall not
be deemed a waiver with respect to any other facts and circumstances and each
such right shall be deemed an ongoing right that may be asserted at any time and
from time to time.
 
     The Merger.  The Merger Agreement provides that, following the consummation
of the Offer and subject to the terms and conditions set forth therein, at the
Effective Time, Purchaser shall be merged with and into the Company and, as a
result of the Merger, the separate corporate existence of Purchaser shall cease,
and the Company shall continue as the Surviving Corporation as a direct
subsidiary of Parent.
 
     The respective obligations of Parent and Purchaser, on the one hand, and
the Company, on the other hand, to consummate the Merger are subject to the
satisfaction at or prior to the Effective Time of each of the following
conditions: (i) if required by applicable law, the Merger Agreement shall have
been approved and adopted by the affirmative vote of the holders of a majority
of the outstanding Shares; (ii) no statute, rule or regulation shall have been
enacted, promulgated or deemed applicable to the Merger by any governmental
entity which prevents the consummation of the Merger or makes the consummation
of the Merger unlawful, and no temporary restraining order, preliminary or
permanent injunction or other order issued by any court of competent
jurisdiction preventing the consummation of the Merger shall be in effect,
provided, however, that each of the parties is obligated to use reasonable
efforts to prevent the entry of any such injunction or other order and to appeal
as promptly as possible any injunction or other order that may be entered; (iii)
all actions by or in respect of or filings with any U.S. federal governmental
entity required to permit the consummation of the Merger shall have been
completed; and (iv) Purchaser shall have purchased all Shares validly tendered
and not withdrawn pursuant to the Offer, provided, however, this condition in
clause (iv) shall not be applicable to the obligations of Parent or Purchaser
if, in breach of the Merger Agreement or the terms of the Offer, Purchaser fails
to purchase any Shares validly tendered and not withdrawn pursuant to the Offer.
 
     At the Effective Time of the Merger, (i) each issued and outstanding Share
(other than Shares that are held by stockholders properly exercising dissenters'
rights under the Delaware General Corporation Law (the "DGCL") and those
referred to in clause (ii) below) shall be canceled and retired and be converted
into the right to receive in cash the same price paid for the Shares in the
Offer (the "Merger Consideration"), (ii) each Share owned by the Company, Parent
or Purchaser or any subsidiary of the Company immediately prior to the Effective
Time shall be canceled and no payment shall be made with respect thereto and
(iii) each share of common stock of Purchaser outstanding immediately prior to
the Effective Time shall be converted into and become one fully paid and
nonassessable share of common stock, par value $.01 per share, of the
 
                                        5
<PAGE>   6
 
Surviving Corporation and shall constitute the only outstanding shares of
capital stock of the Surviving Corporation.
 
     The Company's Board of Directors.  The Merger Agreement provides that
promptly upon the acceptance for payment of, and payment for, Shares by
Purchaser pursuant to the Offer, Purchaser from time to time shall be entitled
to designate such number of directors (rounded up to the next whole number) on
the Board as will give Purchaser, subject to compliance with Section 14(f) of
the Exchange Act, up to that percentage of the total number of directors on the
Board (giving effect to the election of any additional directors described
below) equal to the percentage of then outstanding Shares so accepted for
payment, together with Shares owned by Parent or any of its affiliates, and the
Company will, at such time, cause Purchaser's designees to be so elected by its
existing Board; provided, however, that in the event that such designees are
elected to the Board, until the Effective Time such Board must have at least two
directors who were directors on April 7, 1999 and are not officers of the
Company (the "Independent Directors"); and provided, further, that if the number
of Independent Directors is reduced below two for any reason whatsoever, the
remaining Independent Director shall be entitled to designate a person to fill
such vacancy who shall be deemed to be an Independent Director for purposes of
the Merger Agreement or, if no Independent Directors then remain, the other
directors shall designate two persons to fill such vacancies who shall not be
officers of the Company or stockholders, affiliates or associates of Purchaser
or Parent, and such persons shall be deemed to be Independent Directors for
purposes of the Merger Agreement. Following the election of Purchaser's
designees and prior to the Effective Time, any amendment or termination of the
Merger Agreement or waiver of any of the Company's rights thereunder shall
require the affirmative vote of a majority of the Independent Directors.
 
     Stockholders' Meeting.  Pursuant to the Merger Agreement, the Company will,
if required by the DGCL in order to consummate the Merger, as soon as
practicable following the acceptance for payment of, and payment for, shares by
Purchaser pursuant to the Offer, duly call, give notice of, convene and hold a
meeting of its stockholders to consider and vote upon the approval of the Merger
Agreement and the Merger and all other necessary matters (the "Company
Proposals"), with a record date following the acceptance for payment of, and
payment for, Shares pursuant to the Offer. The Merger Agreement provides that
the Company will, if required, as soon as practicable following the expiration
of the Offer, file with the Commission and, when cleared by the Commission, mail
to stockholders, a proxy statement in connection with a meeting of the Company's
stockholders to vote upon the Company Proposals, or an information statement, as
appropriate, satisfying all requirements of the Exchange Act. If Purchaser
acquires at least a majority of the Shares, it will have sufficient voting power
to approve the Merger, even if no other stockholder votes in favor of the
Merger.
 
     The Merger Agreement provides that in the event that Parent acquires at
least 90% of the Shares, pursuant to the Offer or otherwise, Parent, Purchaser
and the Company will, at the request of Parent, take all necessary and
appropriate action to cause the Merger to become effective as soon as
practicable after the Offer, without a meeting of stockholders of the Company,
in accordance with the DGCL.
 
     Options.  Each option to purchase Shares outstanding immediately prior to
the Effective Time (collectively, "Options"), whether or not then vested or
exercisable, shall at the Effective Time be canceled and be converted into the
right to receive an amount in cash in respect thereof equal to the product of
(1) the excess, if any, of the Merger Consideration over the per Share exercise
price thereof and (2) the number of Shares subject thereto immediately prior to
the Effective Time.
 
     Conduct of Business Pending The Merger.  In the Merger Agreement, the
Company has agreed that, during the period from April 7, 1999 to the Effective
Time, it will, and will cause each of its subsidiaries to, carry on their
respective businesses in the usual, regular and ordinary course in substantially
the same manner as heretofore conducted and in compliance with all applicable
laws and regulations, except where the failure to be in compliance would not,
individually or in the aggregate, have a Material Adverse Effect (as defined in
the Merger Agreement) on the Company and, to the extent consistent therewith,
use reasonable efforts to preserve intact their current business organizations,
keep available the services of their current officers and employees and preserve
their relationships with customers, suppliers, licensors, licensees,
distributors, designers, builders/dealers, contractors and others having
business dealings with them to the end that their goodwill and ongoing
businesses shall be unimpaired in any material respect at the Effective Time.

     foregoing actions.
 
     No Solicitation.  The Merger Agreement provides that the Company shall not,
and shall not permit any of its subsidiaries to, and shall use its reasonable
best efforts to ensure that its officers, directors or employees or any
investment banker, attorney or other advisor or representative retained by it or
any of its subsidiaries do not, (i) solicit, initiate or encourage the
submission of, any Acquisition Proposal (as defined below), or (ii) participate
in any discussions or negotiations regarding, or furnish to any person any
information with respect to, or take any other action to facilitate any
inquiries or the making of any proposal that constitutes, or may reasonably be
expected to lead to, any Acquisition Proposal; provided, however, that prior to
the acceptance for payment of Shares pursuant to the Offer, to the extent
required by the fiduciary obligations of the Board, determined in good faith by
a majority of the disinterested members thereof (after consultation with the
Board's outside counsel and financial advisor), the Company may, in response to
an unsolicited
                                        8
<PAGE>   9
 
Acquisition Proposal that, in the good faith determination by a majority of the
disinterested members of the Board (after consultation with the Board's outside
counsel and financial advisor), constitutes, or is reasonably likely to lead to,
a Superior Proposal, furnish information with respect to the Company to any
third party pursuant to a customary confidentiality agreement (which shall be no
less favorable to the Company than the confidentiality agreement dated as of
March 8, 1999 between Onex and the Company) and discuss such information with
such person and participate in negotiations regarding such Superior Proposal.
"Acquisition Proposal" means any inquiry, proposal or offer from any third party
relating to any direct or indirect acquisition or purchase of a substantial
amount of assets of the Company or any of its subsidiaries, or more than a 20%
interest in any voting securities of the Company or any of its subsidiaries, or
any tender offer or exchange offer that if consummated would result in any
person beneficially owning 20% or more of any class of equity securities of the
Company or any of its subsidiaries, or any merger, consolidation, business
combination, sale of substantially all assets, recapitalization, liquidation,
dissolution or similar transaction involving the Company or any of its
subsidiaries, other than the transactions contemplated by the Merger Agreement.
"Superior Proposal" means a bona fide proposal made by a third party to acquire
the Company pursuant to any merger, sale of all or substantially all of the
Company's assets, consolidation, business combination, recapitalization,
liquidation, dissolution or similar transaction involving the Company or any
transaction that would result in a Change of Control (as defined below) that, in
any case, the Board determines in its good faith judgment (after consultation
with the Board's outside counsel and financial advisor) to be more favorable to
the holders of Shares than the Merger and for which any necessary financing is
then committed. "Change of Control" means any third party shall become the
beneficial owner (within the meaning of Rule 13d-3 under the Exchange Act) of
40% or more of the Company's outstanding common stock.
 
     Pursuant to the Merger Agreement neither the Board nor any committee
thereof is permitted to (i) withdraw or modify, or propose to withdraw or
modify, in a manner adverse to Parent or Purchaser, the approval or
recommendation by the Board or any such committee of the Offer, the Merger
Agreement or the Merger, (ii) approve or recommend, or propose to approve or
recommend, any Acquisition Proposal or (iii) enter into any agreement with
respect to any Acquisition Proposal. Notwithstanding the foregoing, the Board,
to the extent required by the fiduciary obligations thereof, as determined in
good faith by a majority of the disinterested members thereof (after
consultation with the Board's outside counsel and financial advisor), may
(subject to the following limitations), (i) withdraw or modify its approval or
recommendation of the Offer, the Merger Agreement or the Merger, (ii) approve or
recommend any Superior Proposal or (iii) prior to any purchase by Purchaser of
Shares pursuant to the Offer upon satisfaction of the Minimum Condition,
provided the Company simultaneously terminates the Merger Agreement in
accordance with the terms of the Merger Agreement, cause the Company to enter
into a definitive agreement with respect to such Superior Proposal, in each case
provided that (x) a Superior Proposal has been made and not withdrawn and (y)
neither the Company nor any of its subsidiaries shall have violated certain
restrictions set forth in the Merger Agreement.
 
     Board of Directors; Officers.  The Merger Agreement provides that, promptly
upon the acceptance for payment of, and payment for, Shares by Purchaser
pursuant to the Offer, Purchaser shall be entitled to designate members of the
Board, as further described above under the caption "The Company's Board of
Directors." After the time that Purchaser's designees are elected to the Board
and until the Effective Time, any amendment or termination of the Merger
Agreement and any exercise or waiver of the Company's rights under the Merger
Agreement shall also require the approval of a majority of the Independent
Directors.
 
     Under the Merger Agreement, the directors of Purchaser immediately prior to
the Effective Time will be the initial directors of the Surviving Corporation,
and the officers of the Company immediately prior to the Effective Time will be
the initial officers of the Surviving Corporation, in each case until their
respective successors are duly elected or appointed and qualified.
 
     Access to Information.  Pursuant to the Merger Agreement, subject to the
Confidentiality Agreement, the Company shall, and shall cause each of its
subsidiaries to, afford to Parent, and to Parent's officers, employees,
accountants, counsel, financial advisors and other representatives, reasonable
access during normal business hours during the period prior to the Effective
Time to all their respective offices, properties, books, contracts, commitments,
personnel and records, provided that such access shall not interfere with the
normal
                                        9
<PAGE>   10
 
business operations of the Company, and, during such period, the Company shall,
and shall cause each of its subsidiaries to, furnish promptly to Parent (a) a
copy of each report, schedule, registration statement and other document filed
by it during such period pursuant to the requirements of federal or state
securities laws and (b) all other information concerning its business,
properties and personnel as Parent may reasonably request.
 
     Employee Benefits Matters.  Under the Merger Agreement, for a period of at
least 18 months from the Effective Time, the Surviving Corporation will provide
pension, health and welfare benefits to employees of the Company and its
subsidiaries who continue their employment after the Effective Time which are
generally not less favorable in the aggregate to such continuing employees than
the benefits being provided to such continuing employees immediately prior to
the Effective Time. The Surviving Corporation will recognize the service of each
continuing employee through the Effective Time as if such service had been
performed with the Surviving Corporation for purposes of eligibility and vesting
under the Surviving Corporation's benefit plans.
 
     Directors' and Officers' Indemnification and Insurance.  The Merger
Agreement provides that the Company shall, to the fullest extent permitted by
Section 145 of the DGCL and regardless of whether the Merger becomes effective,
indemnify, defend and hold harmless, and after the Effective Time, Parent and
the Surviving Corporation shall, jointly and severally, to the fullest extent
permitted by Section 145 of the DGCL, indemnify, defend and hold harmless each
person who is, or has been at any time prior to the date hereof or who becomes
prior to the Effective Time, an officer or director of the Company or any of its
subsidiaries (collectively, the "Indemnified Parties" and individually, the
"Indemnified Party") against all losses, liabilities, expenses, claims or
damages in connection with any claim, suit, action, proceeding or investigation
based in whole or in part on the fact that such Indemnified Party is or was a
director or officer of the Company or any of its subsidiaries and arising out of
acts or omissions occurring prior to and including the Effective Time (including
but not limited to the transactions contemplated by the Merger Agreement), for a
period of not less than six years following the Effective Time; provided,
however, that in the event any claim or claims are asserted or made within such
six-year period, all rights to indemnification in respect of any such claim or
claims shall continue until final disposition of any and all such claims.
 
     Under the Merger Agreement, Parent has agreed to cause the Certificate of
Incorporation and By-Laws of the Surviving Corporation and its subsidiaries to
include provisions for the limitation of liability of directors and
indemnification of the Indemnified Parties to the fullest extent permitted under
applicable law and not to permit the amendment of such provisions in any manner
adverse to the Indemnified Parties, as the case may be, without the prior
written consent of such persons, for a period of six years from and after the
date of the Merger Agreement. The Merger Agreement further provides that in the
event any such Indemnified Party is or becomes involved in any capacity in any
action, proceeding or investigation in connection with any matter, including,
without limitation, the transactions contemplated by the Merger Agreement,
occurring prior to, and including, the Effective Time, the Surviving Corporation
will pay as incurred such Indemnified Party's legal and other expenses
(including the cost of any investigation and preparation) incurred in connection
therewith, subject to the provision by such Indemnified Party of an undertaking
to reimburse such payments in the event of a final determination by a court of
competent jurisdiction that such Indemnified Party is not entitled thereto. The
Surviving Corporation is obligated to pay all expenses, including attorneys'
fees, that may be incurred by any Indemnified Party in enforcing the indemnity
and other obligations provided for in the Merger Agreement or any action
involving an Indemnified Party resulting from the transactions contemplated by
the Merger Agreement.
 
     In addition, the Merger Agreement provides that for six years after the
Effective Time, the Surviving Corporation shall cause to be maintained policies
of directors' and officers' liability insurance comparable to those currently
maintained by the Company for the benefit of directors and officers of the
Company (provided that the Surviving Corporation may substitute therefor
policies of at least the same coverage containing terms and conditions which are
substantially equivalent) with respect to matters occurring prior to the
Effective Time, provided that the Surviving Corporation is not obligated to
expend in any one year an amount in excess of 200% of the annual premiums
currently paid by the Company for such insurance (the Company has represented
that the annual premium is currently approximately $140,000), and provided
further, that if the
                                       10
<PAGE>   11
 
annual premiums of such insurance coverage exceed such amount, the Surviving
Corporation is obligated to obtain a policy with the greatest coverage available
for a cost not exceeding such amount.
 
     The Merger Agreement further provides that in the event the Company or the
Surviving Corporation or any of their respective successors (i) is consolidated
with or merges into another person and shall not be the continuing or surviving
corporation or entity of such consolidation or merger or (ii) transfers all or
substantially all of its properties and assets to any person in a single
transaction or a series of transactions, then, and in each such case, Parent
shall make or cause to be made proper provision so that the successors or
transferees of the Company or the Surviving Corporation, as the case may be,
shall comply in all material respects with such indemnification and insurance
provisions.
 
     Representations and Warranties.  The Merger Agreement contains customary
representations and warranties with respect to the Company, including, without
limitation, (i) the Company's organization and capitalization, (ii) that the
Board of Directors of the Company has approved the Merger Agreement and the
transactions contemplated thereby (including the Offer and the Merger), (iii)
relating to required consents, approvals and governmental filings, (iv) the
accuracy of the Company's documents and reports filed with the Commission and
the Company's financial statements, (v) the absence of certain changes or events

(vii) the Company's employee benefit plans and other employment matters, (vii)

matters, (x) intellectual property matters, (xi) insurance matters, (xii)
business relationships and restrictive agreements, (xiii) material contracts,
(xiv) product warranties and related matters and (xv) Year 2000 compliance.
 
     In the Merger Agreement, Parent and Purchaser have made customary
representations and warranties, including, without limitation, relating to their
respective corporate organization, authority to execute, deliver and perform the
Merger Agreement, and that Parent has available to it sufficient funds to
consummate the Offer and the Merger in accordance with the terms of the Merger
Agreement.
 
     Conditions to the Merger.  The respective obligations of each party to the
Merger Agreement to effect the Merger are subject to the satisfaction at or
prior to the Effective Time of the following conditions: (a) if required by the
DGCL, the Merger Agreement shall have been approved and adopted by the
affirmative vote of the holders of a majority of the outstanding Shares; (b) no
statute, rule or regulation shall have been enacted, promulgated or deemed
applicable to the Merger by any governmental entity which prevents the
consummation of the Merger or makes the consummation of the Merger unlawful, and
no temporary restraining order, preliminary or permanent injunction or other
order issued by any court of competent jurisdiction preventing the consummation
of the Merger shall be in effect, provided, however, that each of the parties is
obligated to use reasonable efforts to prevent the entry of any such injunction
or other order and to appeal as promptly as possible any injunction or other
order that may be entered; (c) all actions by or in respect of or filings with
any U.S. federal governmental entity required to permit the consummation of the
Merger shall have been completed; and (d) Purchaser shall have purchased all
Shares validly tendered and not withdrawn pursuant to the Offer, provided,
however, that this condition in clause (d) is not applicable to the obligations
of Parent or Purchaser if, in breach of the Merger Agreement or the terms of the
Offer, Purchaser fails to purchase any Shares validly tendered and not withdrawn
pursuant to the Offer.
 
     Termination.  The Merger Agreement may be terminated, and the Merger may be
abandoned, at any time prior to the Effective Time, whether before or after
approval of the Merger by the stockholders of the Company:
 
     (a) by mutual written consent of Parent, Purchaser and the Company (by
action of the Independent Directors only following the purchase of Shares
pursuant to the Offer);
 
     (b) by either Parent or the Company (by action of the Independent Directors
only following the purchase of Shares pursuant to the Offer): (i) if any court
or governmental entity shall have issued an order, decree or ruling or taken any
other action (which order, decree, ruling or other action the parties are
obligated to use their reasonable best efforts to lift) restraining, enjoining
or otherwise prohibiting the Merger and such order, decree, ruling or other
action shall have become final and nonappealable; or (ii) if (x) the Offer shall
have
 
                                       11
<PAGE>   12
 
expired without any Shares being purchased therein or (y) Purchaser shall not
have accepted for payment all Shares tendered pursuant to the Offer by July 14,
1999; provided, however, that the right to terminate the Merger Agreement
pursuant to this clause (ii) shall not be available to any party whose failure
to fulfill any obligation under the Merger Agreement has been the cause of, or
resulted in, the failure of Purchaser to purchase the Shares pursuant to the
Offer on or prior to such date;
 
     (c) by the Company: (i) if Parent and/or Purchaser fails to commence the
Offer as provided in the Merger Agreement; provided, that the Company may not
terminate the Merger Agreement if the Company is at such time in breach of its
obligations under the Merger Agreement such as to (x) cause a Material Adverse
Effect on the Company or (y) prevent the purchase of Shares pursuant to the
Offer or the Merger; (ii) in connection with entering into a definitive
agreement with respect to a Superior Proposal, provided (x) that the Company has
notified Parent in writing of its intent to enter into such definitive agreement
at least three Business Days prior to the termination of the Merger Agreement,
and the relevant Acquisition Proposal continues to be a Superior Proposal
notwithstanding any modification by Parent and Purchaser of the terms of the
Offer and the Merger, (y) that the Company has complied with all relevant
provisions of the Merger Agreement including the notice provisions therein, and
(z) that the Company makes simultaneous payment of the Termination Fee (as
defined below); or (iii) if Parent or Purchaser shall have made a material
misrepresentation or have breached in any material respect any of their
respective representations, covenants or other agreements contained in the
Merger Agreement, which breach cannot be or has not been cured, in all material
respects, within 30 days after the giving of written notice to Parent or
Purchaser, as applicable; or
 
     (d) by Parent: (i) if, due to an occurrence, not involving a breach by
Parent or Purchaser of their obligations under the Merger Agreement, which makes
it impossible to satisfy any of the conditions set forth in Exhibit A to the
Merger Agreement and described above under "Conditions of the Offer", Parent or
Purchaser shall have failed to commence the Offer within five Business Days of
the initial public announcement of the Offer; (ii) if, prior to the purchase of
Shares pursuant to the Offer, the Company shall have breached any
representation, warranty, covenant or other agreement contained in the Merger
Agreement which (A) would give rise to the failure of a condition set forth in
paragraph (e) or (f) of Exhibit A to the Merger Agreement and described above
under "Conditions of the Offer" and (B) cannot be or has not been cured, in all
material respects, within 30 days after the giving of written notice to the
Company; or (iii) (A) if the Board shall have taken any action pursuant to
Section 6.02(b) of the Merger Agreement (including withdrawing or modifying its
approval or recommendation of the Offer, the Merger or the Merger Agreement or
approving or recommending an Acquisition Proposal) or (B) the Company shall have
entered into any definitive agreement with respect to any Superior Proposal.
 
     In the event of the termination of the Merger Agreement and the abandonment
of the Offer and the Merger pursuant to the terms of the Merger Agreement, the
Merger Agreement shall, except as set forth therein, become void and have no
effect, without any liability on the part of any party thereto or its
affiliates, directors, officers or stockholders.
 
     Fees and Expenses.  Except as set forth below, all fees and expenses
incurred in connection with the Offer, the Merger, the Merger Agreement and the
transactions contemplated by the Merger Agreement shall be paid by the party
incurring such fees or expenses, whether or not the Offer or the Merger is
consummated.
 
     The Company is required to pay, or cause to be paid, to Onex a fee equal to
$8,000,000 (the "Termination Fee"), payable in immediately available funds prior
to or concurrently with termination of the Merger Agreement, if the Merger
Agreement is terminated (a) by the Company pursuant to clause (c)(ii) above
under "Termination," or (b) by Parent under clause (d)(iii) above under
"Termination" or (c) by any party for any reason (other than a material breach
of the Merger Agreement by Parent or Purchaser), provided in the case of this
clause (c) only (x) an Acquisition Proposal shall have been made by any third
party at any time on or after the date of the Merger Agreement and prior to such
termination, (y) the Minimum Condition is not satisfied and (z) there is (A) a
merger, sale of all or substantially all of the assets, consolidation, business
combination, recapitalization, liquidation, dissolution or similar transaction
involving the Company or a Change of Control, in any case within six months of
the date of termination of the Merger Agreement or (B) the Company enters into a
definitive agreement for any transaction referred to in
 
                                       12
<PAGE>   13
 
clause (A) or a Change of Control within six months of the date of termination
of the Merger Agreement and such transaction or Change of Control is
subsequently consummated. If the Termination Fee is payable to Onex for any
reason, then the Company is also required to reimburse Parent and its affiliates
not later than two Business Days after submission of reasonable documentation
thereof for 100% of their out-of-pocket fees and expenses (including the
reasonable fees and expenses of counsel), in each case, actually incurred by any
of them or on their behalf in connection with the Merger Agreement and the
transactions contemplated thereby (including the Merger and the arrangement of,
obtaining the commitment to provide or obtaining financing for the transactions
contemplated by the Merger Agreement (including fees payable to any financing
parties and their respective counsel)), up to a maximum reimbursement of
$500,000.
 
     Amendments.  The Merger Agreement may be amended by the parties thereto at
any time before or after any required approval of the Merger by the stockholders
of the Company; provided, however, that after any such approval, there shall be
made no amendment that by law requires further approval by such stockholders
without the further approval of such stockholders. The Merger Agreement may not
be amended except by an instrument in writing signed on behalf of each of the
parties thereto.
 
     Appraisal Rights.  Holders of the Shares do not have appraisal rights in
connection with the Offer. However, if the Merger is consummated, holders of the
Shares at the Effective Time of the Merger will have certain rights pursuant to
the provisions of Section 262 of the DGCL to dissent and demand appraisal of,
and to receive payment in cash of the fair value of, their Shares. Dissenting
stockholders of the Company who comply with the applicable statutory procedures
will be entitled to receive a judicial determination of the "fair value" of
their Shares (exclusive of any element of value arising from the accomplishment
or expectation of the Merger) and to receive payment of such fair value in cash,
together with a fair rate of interest thereon, if any. Any such judicial
determination of the fair value of the Shares could be based upon factors other
than, or in addition to, the price per Share to be paid in the Merger or the
market value of the Shares. The value so determined could be more or less than
the price per Share to be paid in the Merger.
 
     In addition, several decisions by Delaware courts have held that, in
certain circumstances, a controlling stockholder of a company involved in a
merger has a fiduciary duty to other stockholders which requires that the merger
be fair to such other stockholders. In determining whether a merger is fair to
minority stockholders, Delaware courts have considered, among other things, the
type and amount of consideration to be received by the stockholders and whether
there was fair dealing among the parties. The Delaware Supreme Court stated in
Weinberger and Rabkin v. Philip A. Hunt Chemical Corp. that the remedy
ordinarily available to minority stockholders in a cash-out merger is the right
to appraisal described above. However, a damages remedy or injunctive relief may
be available if a merger is found to be the product of procedural unfairness,
including fraud, misrepresentation or other misconduct.

DESIRING TO EXERCISE THEIR DISSENTERS' RIGHTS.

  The Confidentiality Agreement
 
     The following summary of the Confidentiality Agreement is qualified in its
entirety by reference to the complete text of the Confidentiality Agreement, a
copy of which is filed as Exhibit 3 hereto and is incorporated herein by
reference.
 
     Because Onex is an affiliate of Purchaser and Parent, the provisions of the
Confidentiality Agreement are also applicable to Purchaser and Parent.
 
     Pursuant to the Confidentiality Agreement, Onex has agreed, among other
things, to keep confidential certain nonpublic confidential or proprietary
information of the Company furnished to Onex and its representatives by or on
behalf of the Company, including notes, analyses, compilations, studies,
interpretations or other documents prepared by Onex and its representatives
which contain, reflect or are based upon such information ("Evaluation
Material"), and to use the Evaluation Material solely for the purpose of
evaluating a possible transaction with the Company. Onex has further agreed to
maintain the confidentiality of any discussions or negotiations with the Company
and, upon request, to redeliver or destroy all the Evaluation Material. Onex
also agreed that, without the prior written consent of the Company, Onex will
not directly or indirectly enter into any agreement, arrangement or
understanding, or any discussions which might lead to an agreement, arrangement
or understanding, with any other person regarding a possible transaction
involving the Company for a period of two years from the date of the
Confidentiality Agreement. The Confidentiality Agreement further provides that,
for a period of two years from the date of the Confidentiality Agreement,
without the prior written consent of the Board of Directors of the Company,
neither Onex nor any of its affiliates, acting alone or as a part of a group,
may acquire or offer to agree to acquire, directly or indirectly, by purchase or
otherwise, any voting securities (or direct or indirect rights or options to
acquire any voting securities) of the Company, or otherwise seek to influence or
control, in any manner whatsoever, the management or policies of the Company.
For a period of two years from the date of the Confidentiality Agreement,
neither Onex nor any of its affiliates will solicit to employ (whether as an
employee, officer, director, agent, consultant or independent contractor) any
current officer or employee of the Company and its subsidiaries with whom Onex
had contact or who was specifically identified to Onex during its investigation
of the Company, provided that Onex is permitted to hire any such person who
responds to a general advertisement not targeted at such person.
 
ITEM 4.  THE SOLICITATION OR RECOMMENDATION.
 
     (a) RECOMMENDATION OF THE BOARD OF DIRECTORS
 
     The Board of Directors of the Company (the "Board") has unanimously (with
one director not present) approved the Merger Agreement, the Offer and the
Merger and deemed them to be advisable, and has determined that the Offer and
the Merger are fair to and in the best interests of the Company's stockholders,
and unanimously (with one director not present) recommends that the Company's
stockholders accept the Offer and tender their Shares in the Offer.
 
     A letter to the Company's stockholders communicating the Board's
recommendation and a press release announcing the execution of the Merger
Agreement are filed herewith as Exhibits 4 and 5, respectively, and are
incorporated herein by reference.
 
     (b) BACKGROUND; REASONS FOR THE BOARD'S RECOMMENDATION
 
     From time to time beginning in April 1998, the chief executive officer of a
company (the "First Party") with subsidiaries operating in the metal buildings
industry proposed to Robert Ammerman, the Company's chief executive officer,
possible combinations of the two companies. However, no serious discussions
followed.
 
     In May 1998, Mr. Ammerman met with the president of the First Party's
metals group at a meeting of the Metal Building Manufacturers Association, an
industry trade association in which both the Company and the First Party's metal
buildings subsidiaries are members. Mr. Ammerman and this person discussed their
respective companies, the possible synergies to be achieved by combining their
companies and a possible combination.
 
                                       14

     In late June 1998, a representative of Canadian Imperial Bank of Commerce
("CIBC"), the Company's senior lender, contacted William L. Selden, the
Company's Chairman of the Board, to see if he would agree to a meeting with
executives from the First Party, which was a client of CIBC. Mr. Selden was
advised that the First Party had expressed interest through CIBC in a possible
combination with the Company.
 
     On July 6, 1998, Mr. Selden met in New York with the First Party's
president and chief executive officer and its general counsel and a director.
Also attending was a managing director of CIBC. At this meeting, the parties
discussed in general terms their respective businesses. On July 9, 1998, the
First Party's president and chief executive officer sent a follow-up letter to
Mr. Selden setting forth his view of the benefits of a business combination
between the two companies and suggested a follow-up meeting with the management
of both companies attending. During this time, Mr. Selden called each of the
Company's directors and advised them of developments to date.
 
     In early August 1998, the First Party and the Company executed a standard
form of confidentiality agreement, which included certain limitations on the
First Party's ability to pursue transactions involving the Company without the
Company's consent. On August 6, 1998, Messrs. Ammerman, Joel Voelkert, President
of the Company's Construction Products Group, R. Charles Blackmon, Jr., the
Company's Executive Vice President -- Chief Financial Officer, and Mr. Selden
met with the First Party's president and chief executive officer and incoming
chairman, as well as the president of the First Party's metals group and the
president of one of the group's metal buildings subsidiaries. In addition,
several representatives of CIBC were present. At this meeting, the First Party
made a formal presentation of a stock-for-stock merger accounted for as a
pooling-of-interests. Their proposal was based on an exchange ratio that valued
each Share at approximately $30.19 and would have given the Company's
stockholders approximately 31% ownership of the combined company. Also discussed
at this meeting were the various ways the different operations of both companies
could work together.
 
     Following the meeting, Mr. Selden held discussions with each of the
Company's directors; however, the directors had little interest in an all stock
transaction. During this time period, Mr. Selden had numerous phone
conversations with representatives of CIBC to better understand the First
Party's interest in acquiring the Company.
 
     On August 28, 1998, Mr. Selden received a letter from the First Party
proposing a transaction to acquire the Company for $18.50 per Share in cash plus
shares of the First Party's stock which the First Party valued at $18.50 per
Share. At the same time, the First Party sent a due diligence request list, and
the Company assembled and made available to the First Party's representatives
the requested information and documents, other than those containing proprietary
or competitive information.
 
     On September 2, 1998, the Company's Board of Directors held a meeting by
telephone to discuss the First Party's proposal. The Board authorized management
to proceed with discussions with the First Party and to retain Warburg Dillon
Read LLC ("WDR") to provide a fairness opinion should a transaction be agreed to
with the First Party. (See Item 5 below.)
 
     On September 8, 1998, the chief executive officer and the vice
president-finance of the First Party's metals group visited the Company's
executive offices in Eufaula, Alabama for a plant tour and discussions with
Messrs. Ammerman and Blackmon. On September 9, 1998, the same individuals met
again in Columbus, Georgia to continue discussions about a possible merger and
organizational structure.
 
     On September 10, 1998, the Company engaged WDR and paid a $100,000 retainer
fee. During the remainder of September and early October 1998, Mr. Selden held a
number of conversations with the Company's directors, all of whom expressed an
interest in only proceeding with the First Party on an all cash sale basis. Mr.
Selden informed the First Party's chief executive officer of the Board's desire
for an all cash transaction.
 
     On October 7, 1998, the First Party's chief executive officer contacted Mr.
Selden and informed him that the First Party was going to send an all cash
proposal to purchase the Company for approximately $34 per Share. He said that
such a letter would be delivered to Mr. Selden early the following week and that
the First
 
                                       15
<PAGE>   16
 
Party's board of directors had approved making the proposal. Mr. Selden never
received that letter and was not contacted by the First Party's chief executive
officer over the next several weeks.
 
     On October 19, 1998, Mr. Ammerman met with the First Party's chief
executive officer in Chicago, Illinois, to discuss the First Party's strategy
following a merger, organizational structure and the role for the Company's
management in the combined company. Realizing that a transaction between the
Company and the First Party was not imminent, on December 10 and 11, 1998,
Messrs. Ammerman and Voelkert met in Tennessee with the president of the First
Party's metals group and the president of one of the group's metal buildings
subsidiaries to explore the possibility of working together on certain business
opportunities.
 
     On January 4, 1999, Mr. Selden was contacted by a representative of CIBC,
who informed Mr. Selden that his firm no longer was representing the First Party
but that Onex had expressed an interest in looking at the Company. Mr. Selden
informed CIBC's representative that he would be willing to meet with Onex, and
Mr. Selden was then contacted by Mark Hilson, a Vice President of Onex. On
January 12, 1999, Mr. Hilson and Nigel Wright, a principal of Onex, met with Mr.
Selden at his offices in Westport, Connecticut to discuss the Company. Messrs.
Hilson and Wright spoke generally of Onex's possible interest in pursuing an
acquisition of the Company, but did not discuss price or structure.
 
     On January 19, 1999, a regularly scheduled meeting of the Company's Board
of Directors was held in New York. At the meeting Mr. Selden briefed the Board
on Onex's preliminary indication of interest and reviewed with the Board the
prior discussions with the First Party.
 
     On January 28, 1999, Messrs. Hilson and Wright contacted Mr. Selden and
scheduled a telephone call for February 1, 1999. On the February 1, 1999
telephone call, Messrs. Hilson, Wright and Selden discussed generally the
Company's operations and historical results. Messrs. Hilson and Wright again
expressed their possible interest in pursuing an acquisition of the Company,
based upon their research of the industry and publicly available information
about the Company. Mr. Selden requested that Onex express its interest in
writing.
 
     On February 3, 1999, Mr. Selden received a letter from Onex proposing an
all cash acquisition of the Company for $30-$31 per Share through a tender
offer, subject to completion of due diligence. The letter requested that Onex be
granted a 45-day exclusivity period in which to complete due diligence and
negotiate a transaction. Mr. Selden subsequently contacted Mr. Hilson and asked
him to be more specific concerning how Onex would finance this purchase as well
as what financial incentives it would provide the existing Company management.
 
     On February 4 and 5, 1999, Mr. Ammerman met with the president of the First
Party's metals group, the president of one of the group's metal buildings
subsidiaries and several other representatives of the group to tour the
Company's Windsor Door facility in Little Rock, Arkansas and Polymer Coil Coater
facility in Birmingham, Alabama and to discuss the possibility of working
together on certain business opportunities.
 
     During the first week of February 1999, Mr. Selden also received a
telephone call and a letter from a vice president of another entity (the "Third
Party") requesting a meeting to discuss its interest in the Company. On February
8, 1999, Mr. Selden met with a representative of the Third Party at Mr. Selden's
offices in Westport, Connecticut and discussed the general business operations
and prospects of the Company. The Third Party stated that it had a controlling
interest in a company in a related business which operated in both the United
States and Europe. The Third Party stated it was looking at the Company both as
a stand-alone transaction and as a merger candidate with this other entity.
During this week Mr. Selden also had several phone conversations with Messrs.
Hilson and Wright of Onex.
 
     On February 11, 1999, Mr. Selden received a letter from Onex responding to
his questions about its financing and management incentives. On February 19,
1999, Messrs. Hilson, Wright and Selden had a telephone conversation, during
which Onex requested the Company's consent to contact CIBC to discuss CIBC's
interest in possibly financing Onex's acquisition of the Company. This consent
was given on March 24, 1999.
 
                                       16
<PAGE>   17
 
     On February 25, 1999, Mr. Selden received a letter from Onex reiterating
its interest in the Company and further detailing its future plans for the
Company and incentives for management. Onex proposed a 10-day exclusivity period
to allow Onex to complete due diligence and make a final decision whether to
proceed with a transaction. Onex once again stressed that it did not want to
participate in an auction process. During this period, Mr. Selden had several
conversations with each director regarding his discussions with Onex and the
Third Party.
 
     On February 24, 1999, Mr. Selden received a second letter from the Third
Party indicating its interest in purchasing all the Company's stock in a
leveraged recapitalization of the Company for $32 to $34 per Share in cash. The
letter stated that the Third Party would need to complete due diligence.
 
     In late February 1999, Mr. Selden received a telephone call from the First
Party's president and chief executive officer. He told Mr. Selden that he was no
longer going to remain as president and chief executive officer of the First
Party but would remain as a director. He notified Mr. Selden that the First
Party was still interested in acquiring the Company and he suggested that he and
Mr. Selden meet on March 11, 1999 to discuss it. Mr. Selden informed the First
Party that based on the Company's previous experience with the First Party there
was skepticism among the Company's directors about once again discussing a
possible transaction with the First Party but if it was still interested, it
should send him a letter expressing its interest which he would then present to
the Board.
 
     On March 4, 1999, Mr. Selden received a letter from the First Party
proposing an acquisition of the Company at $30 to $33 per Share in cash. The
letter stressed that the First Party needed to conduct further due diligence and
that it would not participate in a public auction.
 
     On March 4, 1999, the Company's Board of Directors met by telephone to
discuss the three unsolicited preliminary indications of interest it had
received from the First Party, Onex and the Third Party with respect to a
possible acquisition of the Company. The Board discussed various alternatives to
the proposals, including continuing as a stand alone company. The Board
authorized the Company's management to meet with each of the interested parties
and to report back to the Board on the meetings, at which time the Board would
determine whether to negotiate a sale of the Company with one of the interested
parties. The Board also approved an amendment to the WDR engagement to
restructure the fee as a result of the increased work required with three
interested parties. (See Item 5 below.)
 
     On March 4, 1999, prior to the meeting of the Board, Messrs. Hilson and
Wright advised Mr. Selden that Onex owned 4.9% of the Shares. Following the
meeting, Messrs. Hilson, Wright and Selden had a second conversation in which
Mr. Selden advised Onex that the Board had received and reviewed three serious
expressions of interest. Mr. Selden informed Messrs. Hilson and Wright that the
Board had instructed management to meet with each interested party and to report
back to the Board.
 
     As of March 8, 1999, the Company entered into confidentiality agreements
with Onex and the Third Party substantially similar to the confidentiality
agreement previously executed with the First Party. (See Item 3 above.)
 
     On March 9, 1999, WDR sent letters to each of the interested parties
confirming the date and time of their meeting with the Company's management. The
letters also set forth an agenda for the meetings, which included a presentation
by the Company's management as well as a presentation by each interested party
with respect to its financing for and ability to close a transaction quickly, as
well as its plans for the Company and the Company's management and employees
post-closing.
 
     Messrs. Ammerman and Blackmon, together with WDR, met with each of the
interested parties on March 11 and 12, 1999 in New York City. Each meeting
involved a general discussion of the Company's operations, financial
performance, 1999 budget and five-year strategic plan, as well as the potential
acquiror's proposed plans for the Company and management following the closing
of a transaction. WDR requested that each interested party firm up its
indication of interest by March 19, 1999. The Company's management and WDR had
several follow-up conversations with the three interested parties during the
week of March 15 to provide additional information and respond to additional
questions.
 
                                       17
<PAGE>   18
 
     On March 18, 1999, Mr. Ammerman met with the incoming chief executive
officer of the First Party to discuss business strategies and strategies for a
combined company, as well as long-term incentive compensation for management.
 
     On March 24, 1999, the Company's Board of Directors met by telephone to
discuss the proposals that had been submitted. David Dickson of WDR summarized
for the Board the meetings management had with each of the interested parties
and reviewed with the Board the proposals submitted by each. Mr. Dickson noted
that the First Party had indicated it was prepared to pay between $30 and $33
per Share, adjusted for any changes in Shares and options outstanding and debt
levels since the Fall of 1998, the Third Party was willing to pay between $31
and $32 per Share and Onex was willing to pay $32 per Share. Mr. Dickson noted
that all three parties stated that they had the financing necessary and there
was no financing contingency to their offer, that each of the interested parties
needed time to complete due diligence and none was willing to proceed without an
exclusive negotiating right. The Board discussed the three proposals, including
an assessment of each party's ability to close a transaction, and determined to
give Onex an exclusive period of up to four weeks to complete its due diligence
and negotiate an agreement. Following the meeting, Mr. Dickson notified each of
the three parties of the Board's decision. Onex and the Company set up a series
of due diligence meetings, beginning with a meeting with the Company's full
management team on March 31, 1999 in Atlanta, Georgia, to be followed by visits
to the Company's facilities during the week of April 5, 1999.
 
     On March 25, 1999, the First Party delivered to the Company a letter
increasing its offer to $34 per Share, subject to due diligence, shortened to
one week the time it needed to complete due diligence (stated to be primarily
environmental and financial) and confirmed it had the necessary financing. WDR,
at the request of the Company, requested that it be permitted to speak with the
First Party's financing source regarding the First Party's financing for a
transaction. WDR notified Onex that the Company had received a higher
unsolicited offer and stated that as a result the Company could not negotiate
with Onex on an exclusive basis. WDR inquired whether Onex would be interested
in participating in an auction or increasing its offer.
 
     During March 25 to 27, 1999, Messrs. Ammerman and Blackmon had several
telephone conversations with Onex and the First Party.
 
     On March 26, 1999, WDR held discussions with the First Party's bank
regarding the First Party's financing for a transaction. That evening, Onex
orally indicated to WDR that it was raising its offer to $34 per Share, that it
would accelerate its due diligence and would be ready to sign an agreement to
acquire the Company by April 2, 1999, but wanted a 4% topping fee rather than
the 3.5% fee proposed in its prior indications of interest. On the evening of
March 28, 1999, Onex reiterated to WDR that it would not participate in an
auction.
 
     From March 29 to March 31, 1999, Messrs. Hilson and Wright met with the
Company's management and visited the Company's Eufaula, Alabama, Little Rock,
Arkansas, and Birmingham, Alabama facilities.
 
     On March 29, 1999, the Company's Board of Directors met by telephone to
discuss the new bids by Onex and the First Party. Mr. Dickson summarized for the
Board developments since the March 24, 1999 meeting. Fulbright & Jaworski L.L.P.
("F&J"), counsel to the Company, reviewed with the Board their fiduciary
responsibilities. The Board then discussed the status of the negotiations and
how to proceed. Following the Board meeting, Mr. Dickson contacted the First
Party's financial advisor to obtain a better understanding of the First Party's
due diligence process and requirements. The First Party's financial advisor said
the First Party needed one week (until April 7, 1999) and would begin due
diligence only if it had an exclusive negotiating right. The First Party's
financial advisor indicated the First Party was willing to increase its offer to
$34.50 per Share if it received an exclusive negotiating right and a $3 million
expense reimbursement if the Company entered into a definitive agreement for a
transaction with another party. However, the First Party's increased offer would
expire at 10:30 p.m. on March 29, 1999 unless accepted. The First Party
subsequently extended its $34.50 offer to 11:30 a.m. on March 30, 1999 to allow
the Company to hold a meeting of its Board of Directors, but the First Party
also stated that in light of the delays it now needed until April 9, 1999 to
complete its due diligence. WDR contacted Onex, indicating that the First Party
had increased its bid; Onex subsequently increased its offer to $34.50 per
Share, but stated it wanted an exclusive negotiating right through April 5,
1999. On March 29, 1999, counsel for Onex delivered to F&J a proposed Agreement
and
                                       18
<PAGE>   19
 
Plan of Merger. On March 29, 1999, F&J sent a proposed Agreement and Plan of
Merger (the "Proposed Agreement") to counsel for the First Party and Onex.
 
     On March 30, 1999, the Company's Board of Directors met by telephone to
discuss the revised bids from the First Party and Onex. Mr. Dickson summarized
for the Board the developments over the past 24 hours and Mr. Selden reviewed
with the Board the Company's prior discussions with the First Party. The Board
discussed both proposals, including the conditions attached to each. The Board
determined that the First Party's request for a $3 million expense reimbursement
in connection with the grant of an exclusive negotiating right was unacceptable.
The Board also considered the Company's past negotiations with the First Party.
F&J reviewed with the Board the written exclusivity agreement requested by Onex,
which gave the Board the right to terminate the exclusivity right if it
determined it was required to do so in the exercise of its fiduciary duties. The
Board authorized the Company to enter into the exclusivity agreement with Onex.
 
     Following the meeting of the Board of Directors, the Company entered into
the exclusivity agreement with Onex, and WDR notified the First Party of the
Board's decision. The First Party subsequently orally notified WDR that it would
be sending a new offer at $35.50 per Share, subject to completion of limited
confirmatory due diligence. A letter confirming the new offer, which was
received by the Company in the evening, stated that the First Party's offer
expired at noon on March 31, 1999. On March 30, 1999, counsel for Onex began to
review documents at the data room at F&J.
 
     On March 31, 1999, the Company's Board of Directors held a meeting by
telephone. F&J summarized developments over the past 24 hours. The Board then
discussed three possible alternatives: (i) continue with Onex under the
exclusivity agreement; (ii) conduct a formal auction, which would involve WDR
going out and determining if there were other parties interested in acquiring
the Company; or (iii) terminating the exclusivity agreement with Onex and giving
both the First Party and Onex an opportunity to finish due diligence and put in
a firm offer. The Board determined to proceed with the last alternative, and
instructed WDR to also contact the Third Party to determine if it was still
interested in acquiring the Company. The Board determined not to proceed with a
formal auction because it would lengthen the process, Onex and the First Party
had stated that they would not participate in an auction and if, following an
announcement of a transaction a third party was interested in acquiring the
Company at a higher price, the Company would have the right to terminate the
agreement entered into in connection with such transaction. Following the
meeting, WDR sent letters to each of the First Party and Onex notifying them
that no exclusive negotiating right would be granted and that the Board had
scheduled a meeting for April 7, 1999 at 1:00 p.m. to consider any proposals and
to take whatever action it deemed to be in the best interests of stockholders.
The Company also notified Onex that it was terminating its exclusivity
arrangement based on its fiduciary duty to consider the First Party's offer. The
Third Party was contacted by WDR but declined to participate.
 
     On April 1, 1999, the First Party sent the Company its due diligence list
of information and documents it desired to review. On April 1 and 2, 1999, the
president of the First Party's metals group and other representatives met with
the Company's management and, together with Mr. Ammerman, visited the Company's
El Paso, Illinois, Little Rock, Arkansas, Birmingham, Alabama and LaCrosse,
Virginia manufacturing facilities. On April 1, 2 and 5, 1999, environmental
consultants engaged by the First Party visited each of the Company's facilities.
On April 1, 2 and 3, 1999, representatives of the First Party and its counsel
reviewed the various due diligence documents in the data room at F&J. In
addition, Mr. Blackmon had numerous telephone conversations with representatives
of the First Party, including its investment bankers and counsel.
 
     On April 1, 1999 and over the next several days, Messrs. Hilson and Wright
had several conversations with Messrs. Ammerman and Blackmon regarding follow-up
questions, and counsel for Onex continued to review the due diligence documents
made available by F&J and the Company.
 
     On April 3, 1999, counsel for the First Party delivered a mark-up of the
Proposed Agreement to F&J. On April 5, 1999, counsel for the First Party and F&J
met by telephone to discuss the First Party's comments on the Proposed
Agreement. F&J circulated a revised draft of the Proposed Agreement to counsel
for the First Party on April 6, 1999.
 
                                       19

     On April 5, 1999, Messrs. Ammerman and Blackmon met with members of Onex
management, including Messrs. Hilson and Wright, in Toronto, Canada for further
due diligence meetings. On April 5, 1999, counsel for Onex delivered a mark-up
of the Proposed Agreement to F&J. Representatives of both Onex and the First
Party continued their due diligence examination of the Company.
 
     On April 6, 1999, Messrs. Ammerman and Blackmon had telephone conversations
with representatives of Onex and the First Party, including a conversation with
representatives of the First Party and their investment bankers to review the
First Party's financial model. On April 6, 1999, F&J held discussions with
counsel for Onex and counsel for the First Party with respect to the respective
Proposed Agreements with Onex and the First Party.
 
     On April 7, 1999, F&J continued to negotiate with counsel for Onex and
counsel for the First Party to finalize the respective Proposed Agreements with
Onex and the First Party. Immediately prior to the Board meeting both Onex and
the First Party submitted their respective offers in writing. At 1:00 p.m. on
April 7, 1999, the Company's Board of Directors met in person at the offices of
F&J. All of the directors except one were present; the absent director was in
Japan. Mr. Blackmon and representatives of F&J and WDR attended the meeting. F&J
summarized for the Board the activities that had occurred since the March 31,
1999 meeting, and then reviewed with the Board the terms of the Proposed
Agreement with each of Onex and the First Party. The Board was then informed
that the First Party's offer was $35.50 per Share and Onex's offer was $36.00
per Share. WDR then reviewed with the Board its financial analysis of the
transaction, and orally delivered its opinion, subsequently confirmed in
writing, that the consideration to be received by the holders of the Shares from
Onex was fair to such holders from a financial point of view. The directors then
discussed the transaction. Following and based upon such discussion, the Board
unanimously (with one director not present) (i) determined that the Merger
Agreement and the terms of the Offer and the Merger were fair to, and in the
best interests of, the Company's stockholders, (ii) approved and adopted the
Merger Agreement and the transactions contemplated thereby, including the Offer
and the Merger, and deemed them to be advisable and (iii) resolved to recommend
that the stockholders of the Company accept the Offer, tender their Shares
thereunder to Purchaser and approve and adopt the Merger Agreement and the
Merger.
 
     Following the Board meeting, the Company and Onex signed the Merger
Agreement and the transaction was announced prior to the opening of the Nasdaq
National Market on April 8, 1999.
 
     Following execution of the Merger Agreement, WDR contacted the First
Party's financial advisors and informed them that the Company had entered into
the Merger Agreement with Onex. The First Party's financial advisors
subsequently informed WDR that the First Party was prepared to offer $37.00 per
Share if the Merger Agreement had not been signed. WDR reiterated that the
Merger Agreement had been signed.
 
     Reasons for the Board's Conclusions.  In approving the Merger Agreement and
the transactions contemplated thereby and recommending that all holders tender
their Shares pursuant to the Offer, the Board considered a number of factors,
including the following:
 
          (i) The Board's familiarity with, and information provided by the
     Company's management as to, the business, financial condition, results of
     operations, current business strategy and future prospects of the Company,
     as well as the risks involved in achieving those prospects and objectives
     in current industry and market conditions, the nature of the markets in
     which the Company operates, the Company's position in such markets, and the
     historical and current market prices for the Shares.
 
          (ii) The terms of the Merger Agreement, including (x) the proposed
     structure of the Offer and the Merger involving an immediate cash tender
     offer followed by a merger for the same consideration and (y) the fact that
     financing is not a condition to the Offer and the Merger, thereby enabling
     stockholders to obtain cash for their Shares quickly.
 
          (iii) That the per Share price contemplated by the Merger Agreement,
     at $36.00, represented a significant premium of approximately 85% to the
     trading prices of the Shares immediately prior to the March 4, 1999
     decision of the Board of Directors to pursue negotiations with the three
     interested parties, and approximately 65% to the trading prices of the
     Shares immediately prior to the announcement of the execution of the Merger
     Agreement.

          (iv) The process engaged in by the Company's management and financial
     advisor, which included discussions with a number of potential acquirors,
     as a result of which the Board had what it believed to be an accurate sense
     of the values that could be achieved in a third party transaction.
 
          (v) The presentation of WDR at the April 7, 1999 Board meeting and the
     opinion of WDR to the effect that, as of such date, and based on the
     assumptions made, matters considered and limits of review set forth
     therein, the consideration to be paid by Purchaser to the holders of the
     Shares in the Offer and the Merger is fair to such holders from a financial
     point of view. The full text of the written opinion of WDR, dated April 7,
     1999, which sets forth the assumptions made, matters considered and
     limitations on the review undertaken in connection with the opinion, is
     attached to this Statement as Annex B and is incorporated herein by
     reference. The opinion of WDR referred to herein does not constitute a
     recommendation as to whether or not any holder of Shares should tender such
     Shares in connection with the Offer. All stockholders are urged to, and
     should, read the opinion of WDR carefully in its entirety.
 
          (vi) That the Merger Agreement permits the Company to furnish
     nonpublic information to, and to participate in negotiations with, any
     third party that has submitted an Acquisition Proposal that constitutes, or
     is reasonably likely to lead to, a Superior Proposal, if the Board
     determines in good faith that taking such action is necessary in the
     exercise of its fiduciary obligations under applicable law, and the Merger
     Agreement permits the Company's Board to terminate the Merger Agreement in
     certain circumstances in the exercise of its fiduciary duties.
 
          (vii) The termination provisions of the Merger Agreement, which under
     certain circumstances could obligate the Company to pay a termination fee
     of $8 million to Onex and reimburse Onex for its actual expenses incurred
     in connection with the transaction, up to $500,000, and the Board's belief
     that such fees and expense reimbursement provisions would not deter a
     higher offer.
 
          (viii) The likelihood that the transaction would be consummated,
     including the conditions to the Offer, and Onex's financial strength,
     including its undertaking to provide Purchaser with all necessary funds to
     purchase the Shares.
 
          (ix) A consideration of alternatives to the sale of the Company,
     including without limitation continuing to operate the Company as a public
     company and not engaging in any extraordinary transaction.
 
     The foregoing discussion addresses the material information and factors
considered by the Board in its consideration of the Offer. In view of the
variety of factors and the amount of information considered, the Board did not
find it practicable to provide specific assessments of, quantify or otherwise
assign relative weights to the specific factors considered in reaching its
determination. The determination to recommend that stockholders accept the Offer
was made after consideration of all of the factors taken as a whole. In
addition, individual members of the Board may have given different weights to
different factors.
 
ITEM 5.  PERSONS RETAINED, EMPLOYED OR TO BE COMPENSATED.
 
     The Company initially retained WDR as its financial advisor with respect to
a transaction with the First Party or any other Transaction (as defined below)
pursuant to an engagement letter dated September 10, 1998 (the "September
Engagement"). Pursuant to the September Engagement, the Company agreed to pay
WDR as follows: (i) a retainer of $100,000; (ii) a fee of $100,000 upon the
earlier of (a) presentation by WDR to the Board of an analysis of the value of
the First Party both as a stand-alone entity and on a combined basis with the
Company or (b) the payment required by clause (iii) below; and (iii) $550,000
upon delivery of a written opinion relating to the fairness from a financial
point of view of the consideration to be received by the holders of Shares in a
transaction with the First Party. The September Engagement also provided that if
WDR assisted in materially changing the terms of the First Party's August 28,
1998 proposal, or if the Company consummated a Transaction with any entity other
than the First Party during the six month term of the September Engagement (the
"Term") or within 12 months following the end of the Term with any other entity
which approached the Company or WDR during the Term, the Company would pay WDR a
fee equal
 
                                       21
<PAGE>   22
 
to 1% of the aggregate consideration paid to the Company and/or its stockholders
(less any amounts already paid to WDR).
 
     On March 9, 1999, the Company and WDR amended the terms of the September
Engagement (the "Amended Engagement") to provide that if the Company consummated
a Transaction with the First Party, Onex or the Third Party (collectively, the
"Current Bidders") during, or within 12 months after the end of, the Term, it
would receive a fee of $2,000,000 upon consummation, of which $100,000 had been
paid in September 1998. The Amended Engagement also provided that the Term was
extended to March 9, 2000, and that if the Company consummated a Transaction
during the Term with any entity other than a Current Bidder or within 12 months
after the end of the Term, it would pay a fee to WDR equal to the greater of
$2,000,000 or 1% of the aggregate consideration paid to the Company and/or its
stockholders, less any amounts previously paid. If the transactions contemplated
by the Merger Agreement are consummated, WDR will receive aggregate fees of
$2,000,000.
 
     A "Transaction" means any transaction pursuant to which any person or
entity acquires a controlling interest in the capital stock or assets of the
Company, whether by way of acquisition, merger, consolidation, reorganization or
other business combination, a tender or exchange offer, a recapitalization or
otherwise.
 
     The Company has also agreed to reimburse WDR for its reasonable expenses
(including, without limitation, professional and legal fees and disbursements)
incurred in connection with its engagement with respect to the services to be
rendered by it, up to $50,000, and to indemnify WDR against certain liabilities
in connection with its engagement.
 
     In the ordinary course of business, WDR and its affiliates may actively
trade or hold the securities of the Company and Onex and their affiliates for
its own account or for the account of customers and, accordingly, may at any
time hold a long or short position in such securities.
 
     Neither the Company nor any person acting on its behalf has employed,
retained or compensated any other person to make solicitations or
recommendations to the Company's stockholders on its behalf with respect to the
Offer or the Merger.
 
ITEM 6.  RECENT TRANSACTIONS AND INTENT WITH RESPECT TO SECURITIES.
 
     (a) During the past 60 days, no transactions in the Shares have been
effected by the Company or, to the best of the Company's knowledge, by any
executive officer, director, affiliate or subsidiary of the Company, except

          (i) On February 25, 1999, each non-employee director of the Company
     automatically received an option to purchase 5,000 Shares at a purchase
     price of $20.563, the closing price of the Shares on such date, under the
     Company's Stock Option Plan for Non-Employee Directors.
 
          (ii) The Company repurchased an aggregate of 131,500 Shares pursuant

     (b) To the best knowledge of the Company, all of its executive officers,
directors, affiliates and subsidiaries currently intend to tender pursuant to
the Offer all Shares held of record or beneficially owned by them (other than
Shares issuable upon the exercise of stock options and Shares, if any, which if
tendered could cause such persons to incur liability under the provisions of
Section 16(b) of the Securities Exchange Act of 1934, as amended).
 
ITEM 7.  CERTAIN NEGOTIATIONS AND TRANSACTIONS BY THE SUBJECT COMPANY.
 
     (a) Prior to entering into the Merger Agreement, the Company had
substantial discussions with other entities that had expressed interest in the
Company, as more fully described in Item 4 above. Upon execution of the Merger
Agreement, the Company ceased contacts with such other entities. Except as set
forth in this Schedule 14D-9, the Company is not engaged in any negotiation in
response to the Offer which relates to or would result in (i) an extraordinary
transaction, such as a merger or reorganization, involving the Company or any
subsidiary of the Company, (ii) a purchase, sale or transfer of a material
amount of assets by the Company or any subsidiary of the Company, (iii) a tender
offer for or other acquisition of securities by or of the Company or (iv) any
material change in the present capitalization or dividend policy of the Company.
 
     (b) Except as set forth herein, there are no transactions, board
resolutions, agreements in principle or signed contracts in response to the
Offer which relate to or would result in one or more of the matters referred to
in paragraph (a) of this Item 7.
 
ITEM 8.  ADDITIONAL INFORMATION TO BE FURNISHED.
 
     (a) The Information Statement attached as Annex A hereto is being furnished
in connection with the possible designation by Purchaser, pursuant to the Merger
Agreement, of certain persons to be appointed to the Board other than at a
meeting of the Company's stockholders.
 
     (b) As a Delaware corporation, the Company is subject to Section 203
("Section 203") of the DGCL. Under Section 203, certain "business combinations"
between a Delaware corporation whose stock is publicly traded or held of record
by more than 2,000 stockholders and an "interested stockholder" are prohibited
for a three-year period following the date that such a stockholder became an
interested stockholder, unless, among other possible exemptions, prior to the
time such stockholder became an interested stockholder the board of directors of
the corporation approved the business combination or the transaction which
resulted in the stockholder becoming an interested stockholder. The term
"business combination" is defined generally to include mergers or consolidations
between a Delaware corporation and an interested stockholder, transactions with
an interested stockholder involving the assets or stock of the corporation or
its majority-owned subsidiaries and transactions which increase an interested
stockholder's percentage ownership of stock. The
 
                                       23
<PAGE>   24
 
term "interested stockholder" is defined generally as a stockholder who,
together with affiliates and associates, owns (or, within three years prior, did
own) 15% or more of a Delaware corporation's voting stock. An owner includes a
person who has the right to acquire such stock, including upon the exercise of
an option.
 
     In accordance with the Merger Agreement and Section 203, at its meeting on
April 7, 1999, the Board unanimously approved the Offer and the Merger and
determined to make the restrictions of Section 203 inapplicable to the Offer,
the Merger and any purchases of Shares by Onex following the acquisition of
Shares pursuant to the Offer.

                           AND RULE 14f-1 THEREUNDER
 
     This Information Statement is being mailed on or about April 13, 1999, as
part of the Solicitation/ Recommendation Statement on Schedule 14D-9 (the
"Schedule 14D-9") of American Buildings Company (the "Company") with respect to
the Offer to Purchase dated April 13, 1999 of ABCO Acquisition Corp.
("Purchaser"), a wholly owned subsidiary of ABCO Holdings Corp. ("Parent") and
an indirect wholly-owned subsidiary of Onex Corporation ("Onex"). Purchaser is
offering to purchase all shares of common stock, par value $.01 per share (the
"Common Stock"), of the Company currently outstanding and not owned directly or
indirectly by Parent, Purchaser or the Company (the "Shares"), at a price of $36
per Share, net to the seller in cash (the "Offer"). The Offer is being made
pursuant to the Agreement and Plan of Merger dated as of April 7, 1999, by and
among the Company, Parent and Purchaser (the "Merger Agreement"). You are
receiving this Information Statement in connection with the possible election of
persons designated by Purchaser (the "Purchaser Designees") to a majority of the
seats on the Board of Directors of the Company (the "Board") pursuant to the
Merger Agreement. The Merger Agreement is more fully described under Item 3 of
the Schedule 14D-9, to which this Information Statement is attached as Annex A.
Capitalized terms used and not otherwise defined herein have the meanings
ascribed to them in the Schedule 14D-9.
 
     The information with respect to the Purchaser Designees has been supplied
to the Company by Parent and Purchaser, and the Company assumes no
responsibility for the accuracy or completeness of such information.
 
     This Information Statement is required to be delivered to you by Section
14(f) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
and Rule 14f-1 thereunder. You are urged to read this Information Statement
carefully. You are not, however, required to take any action.
 
RIGHT TO DESIGNATE DIRECTORS; THE PURCHASER DESIGNEES
 
     Pursuant to the Merger Agreement, promptly upon the acceptance for payment
of, and payment for, Shares by Purchaser pursuant to the Offer, Purchaser is
entitled to designate such number of members of the Board, rounded up to the
next whole number, equal to the product of (i) the total number of directors on
the Board (giving effect to the directors designated pursuant to this provision)
multiplied by (ii) the percentage that such number of Shares so accepted for
payment, together with any other Shares owned by Parent and its affiliates,
bears to the total number of Shares outstanding. Notwithstanding the foregoing,
the Merger Agreement further provides that at least two directors who were
directors of the Company as of April 7, 1999, the date of the Merger Agreement,
and who are not officers of the Company (each such director, an "Independent
Director") shall continue to serve on the Board until the effectiveness of the
Merger, provided that, in such event, if the number of Independent Directors
shall be reduced below two for any reason whatsoever, any remaining Independent
Directors (or Independent Director, if there be only one remaining) shall be
entitled to designate persons to fill such vacancies who shall be deemed to be
Independent Directors for purposes of the Merger Agreement or, if no Independent
Director then remains, the other directors shall designate two persons to fill
such vacancies who shall not be officers of the Company or stockholders,
affiliates or associates of Purchaser or Parent and such persons shall be deemed
to be Independent Directors for purposes of the Merger Agreement. The Company
has agreed to take all actions available to it to cause the Purchaser Designees
to be elected to the Board as provided above, including using its reasonable
best efforts to either increase the size of the Board or to secure the
resignation of such number of its incumbent directors, or both, as is necessary.
Following the election of Purchaser's designees and prior to the Effective Time,
any
<PAGE>   27
 
amendment or termination of the Merger Agreement or waiver of any of the
Company's rights thereunder shall require the affirmative vote of a majority of
the Independent Directors.
 
     Purchaser has informed the Company that it will choose the Purchaser
Designees from the directors and executive officers of Parent and its affiliates
listed on Schedule I attached hereto. Purchaser has informed the Company that
each of the individuals listed on Schedule I has consented to act as a director,
if so designated.
 
     It is expected that the Purchaser Designees may assume office at any time
following the purchase by Purchaser pursuant to the Offer of such number of
Shares as represents not less than a majority of the outstanding Shares on a
fully diluted basis, which purchase cannot be earlier than May 11, 1999.
 
CERTAIN INFORMATION CONCERNING THE COMPANY
 
     The Common Stock is the only class of voting securities of the Company
outstanding. Each share of Common Stock entitles its holder to one vote. As of
April 6, 1999, there were 5,076,180 shares of Common Stock outstanding. The
Board is currently comprised of seven members, although one of the directors is
not standing for re-election at the Company's Annual Meeting of Stockholders,
which is being held on April 27, 1999. Pursuant to the Company's By-laws,
directors are elected annually. Vacancies in the Board may be filled by the
Board, and any director chosen to fill a vacancy will hold office until the next
election of directors.

     The Company has adopted a Stock Option Plan for Non-Employee Directors (the
"Directors' Option Plan"), pursuant to which options to acquire a maximum of
260,000 shares of Common Stock may be granted to non-employee directors. Options
granted under the Directors' Option Plan do not qualify as incentive stock
options within the meaning of Section 422 of the Internal Revenue Code of 1986,
as amended (the "Code"). The Directors' Option Plan provided that upon adoption
of the plan, each of Messrs. Levy, Newhouse, Saul, Selden, Shapiro and Wilson,
its current non-employee directors, was granted an option to purchase 7,500
shares of Common Stock at a purchase price per share equal to the initial public
offering price of the Common Stock ($10.00). The Directors' Option Plan provides
for the automatic grant to each of the Company's non-employee directors of (1)
an option to purchase 7,500 shares of Common Stock on the date of such
director's initial election or appointment to the Board of Directors (the
"Initial Grant"), and (2) an option to purchase 5,000 shares of Common Stock
(1,500 shares prior to 1999) on each annual anniversary of such election or
appointment, provided that such individual is a non-employee director on such
anniversary date (the "Additional Grant"). The options have an exercise price of
100% of the fair market value of the Common Stock on the date of grant and have
a ten-year term. The Initial Grant becomes exercisable in four equal
installments on the six month anniversary of the date such person was first
elected or appointed to the Board of Directors and on the first, second and
third anniversary of the date of such election or appointment. The Additional
Grant becomes exercisable in four equal installments on the six month
anniversary of the date of each Additional Grant and on the first, second and
third anniversary of the date of such Additional Grant. All options granted
under the Directors' Option Plan become immediately exercisable upon a change of
control of the Company (as defined in the Directors' Option Plan). The options
may be exercised by payment in cash, check or shares of Common Stock. On
February 25, 1996, 1997 and 1998, each of Messrs. Levy, Newhouse, Saul, Selden,
Shapiro and Wilson was granted an option to purchase 1,500 shares of Common
Stock at a purchase price of $21.125, $27.00 and $29.625, respectively, the
closing price of the Common Stock on such dates, and on February 25, 1999 each
non-employee director was granted an option to purchase 5,000 shares of Common
Stock at a purchase price of $20.563, the closing price of the Common Stock on
such date, under the Directors' Option Plan. The consummation of the Offer would
constitute a change of control of the Company under the Directors' Option Plan.

(1) For each of 1998, 1997, and 1996, represents bonuses paid during the
    following year for services rendered in that year. In 1996, the Company
    adopted a Shareholder Value Added Plan for key senior and middle management
    executives. The plan entitles participants to receive cash bonuses based on
    a fixed percentage of Shareholder Value Added (as defined in the plan) and
    the change in Shareholder Value Added. Does not include amounts allocated to
    the Shareholder Value Added Plan's bank, which amounts are subject to change
    based on the Company's performance and will be paid in future years if the
    individual remains with the Company. At December 31, 1998, the bank balance
    for Messrs. Ammerman, Voelkert, Blackmon, Buchholz and Smith was $74,370,
    $42,692, $24,309, $23,154, and $8,846, respectively. These amounts become
    vested and payable upon a change of control of the Company (as defined in
    the Shareholder Value Added Plan). The consummation of the Offer would
    constitute a change of control of the Company under the Shareholder Value
    Added Plan.

    Ammerman, Voelkert, Blackmon, Buchholz and Smith, respectively. The Company
    is obligated to contribute at least 25% of the amount of compensation
    elected to be deferred by such individual; however, the Company has the
    opportunity to increase this amount. In addition, the Company is required to
    contribute 1% of its eligible gross payroll to participants in the Savings
    Plan pursuant to a formula based on compensation and years of service (the
    "Additional Contribution"). In 1996, 1997 and 1998, the Company contributed
    25%, 40% and 25% of the amount of compensation elected to be deferred by
    each named individual plus the Additional Contribution to each named
    individual. The balance of the amounts in this column consists of insurance
    premiums on term life insurance paid by the Company for the benefit of the
    named individuals and a car allowance for each of Messrs. Ammerman,
    Voelkert, Blackmon, Buchholz and Smith.
 
(3) Includes bonuses paid from the Windsor Door shareholder value added plan in
    1999 for services rendered in 1998 of $16,626 and $5,987 for Messrs.
    Ammerman and Blackmon, respectively.
 
(4) Includes a bonus of $63,000 paid in 1999 based on the Polymer Coil Coater
    division's 1998 performance, a bonus of $58,500 paid in 1998 based on that
    division's 1997 performance and a bonus of $52,000 paid in 1997 based on
    that division's 1996 performance.
 
STOCK OPTIONS
 
     No grants of stock options were made during the year ended December 31,
1998 to the persons named in the Summary Compensation Table. However, on January
19, 1999, the Company granted options to purchase an aggregate of 30,000 shares,
15,000 shares, 15,000 shares, 5,000 shares and 15,000 shares to each of Messrs.
Ammerman, Voelkert, Blackmon, Buchholz and Smith, respectively, at an exercise
price of $23.50 per share, equal to the closing price of the Common Stock on the
date of grant. The options are exercisable in four equal annual installments
commencing January 19, 2000; provided that the options will become immediately
exercisable upon a change of control of the Company (as defined in the option
plan pursuant to which the options were issued). The consummation of the Offer
would constitute a change of control of the Company for purposes of these
options.
 
     The following table sets forth the aggregate options exercised during the
year ended December 31, 1998 and the number of securities underlying unexercised

MANAGEMENT RETIREMENT AND DEATH BENEFIT PLAN
 
     The Company has a noncontributory retirement and death benefit plan which
covers certain management employees. The plan provides a death benefit if a
covered employee dies prior to reaching retirement age, as defined by the plan,
to be paid over a minimum ten-year period and a mutually exclusive retirement
benefit, after reaching the defined retirement age, to be paid over a ten-year
period. Termination of employment with the Company for any reason prior to
reaching this defined retirement age results in plan members forfeiting all
 
                                       A-8
<PAGE>   34
 
benefit rights and claims. Benefits under this plan do not vest until retirement
or, if earlier, death, and the Company has the right to modify or terminate this
plan at any time.
 
EMPLOYMENT AGREEMENTS
 
     The Company has entered into employment agreements, effective as of January
1, 1998, with each of Robert Ammerman, Charles Blackmon, William Buchholz, Roy
Smith and Joel Voelkert for terms ending December 31, 2000. Each of the
foregoing agreements (collectively, the "Employment Agreements") provides for
automatic renewal for successive one year terms unless either party notifies the
other to the contrary at least 90 days prior to its expiration. The agreements
require each employee to devote substantially all of his time and attention to
the business of the Company as necessary to fulfill his duties. The agreements
provide for the payment of a base salary for 1999 to Messrs. Ammerman, Blackmon,
Buchholz, Smith and Voelkert at a rate of $412,000, $170,000, $160,000, $132,000
and $215,000, respectively. Mr. Ammerman's agreement also provides for minimum
annual salary increases based on increases in the cost of living. The agreements
also provide for the payment of bonuses in such amounts as may be determined by
the Board. Under the agreements, the employee may terminate his employment upon
30 days' notice. The agreements provide that in the event the employee's
employment is terminated by the Company at any time for any reason other than
justifiable cause, disability or death, the Company shall pay the employee the
employee's base salary and permit participation in benefit programs for the
greater of (i) the remaining term of the agreement or (ii) one year (two years
in the case of Mr. Ammerman); however, if such termination occurs at any time
within one year following a "Change of Control of the Company," the Company
shall pay the employee a lump sum payment equal to two years' annual salary plus
an amount equal to twice the employee's most recently declared bonus, and permit
participation in benefit programs for the period specified above. The Employment
Agreements also provide that in the event the Company chooses not to renew the
agreement, the Company shall pay the employee his base salary for a period of
one year. Each agreement contains confidentiality provisions, whereby each
executive agrees not to disclose any confidential information regarding the
Company, as well as non-competition covenants. The non-competition covenants
survive the termination of an employee's employment for the greater of (i) the
remaining term of the agreement or (ii) two years, except in the event the
Company elects not to renew the agreement, terminates the employee's employment
within one year following a "Change in Control of the Company" or fails to make
required severance payments.
 
     For purposes of the Employment Agreements, a "Change in Control of the
Company" shall be deemed to occur if (i) there shall be consummated (x) any
consolidation or merger of the Company in which the Company is not the
continuing or surviving corporation or pursuant to which shares of the Company's
Common Stock would be converted into cash, securities or other property, other
than a merger of the Company in which the holders of the Company's Common Stock
immediately prior to the merger have the same proportionate ownership of common
stock of the surviving corporation immediately after the merger, or (y) any
sale, lease, exchange or other transfer (in one transaction or a series of
related transactions) of all, or substantially all, of the assets of the
Company, or (ii) the stockholders of the Company shall approve any plan or
proposal for liquidation or dissolution of the Company, or (iii) any person (as
such term is used in Sections 13(d) and 14(d)(2) of the Exchange Act), shall
become the beneficial owner (within the meaning of Rule 13d-3 under the Exchange
Act) of 40% or more of the Company's outstanding Common Stock other than
pursuant to a plan or arrangement entered into by such person and the Company,
or (iv) during any period of two consecutive years, individuals who at the
beginning of such period constitute the entire Board of Directors shall cease
for any reason to constitute a majority thereof unless the election, or the
nomination for election by the Company's stockholders, of each new director was
approved by a vote of at least two-thirds of the directors then still in office
who were directors at the beginning of the period.
 
     The Employment Agreements also provide that if, in connection with a change
of ownership or control of the Company or a change in ownership of a substantial
portion of the assets of the Company (all within the meaning of Section
280G(b)(2) of the Code), an excise tax is payable by the employee under Section
4999 of the Code, then the Company will pay to the employee additional
compensation which will be sufficient to enable the employee to pay such excise
tax as well as the income tax and excise tax on such additional
 
                                       A-9
<PAGE>   35
 
compensation, such that, after the payment of income and excise taxes, the
employee is in the same economic position in which he would have been if the
provisions of Section 4999 of the Code had not been applicable.
 
     The consummation of the Offer would constitute a Change of Control of the
Company under the Employment Agreements.
 
                 COMPENSATION COMMITTEE REPORT TO STOCKHOLDERS
 
     The report of the Compensation Committee (the "Compensation Committee")
shall not be deemed incorporated by reference by any general statement
incorporating by reference this Information Statement into any filing under the
Securities Act of 1933, as amended (the "Securities Act"), or under the Exchange
Act, except to the extent that the Company specifically incorporates this
information by reference, and shall not otherwise be deemed filed under such
Acts.
 
     The Compensation Committee of the Board of Directors was formed in February
1993 and consists of Messrs. Newhouse and Shapiro, each of whom is an
independent non-employee director. The Compensation Committee administers the
Company's executive compensation programs, monitors corporate performance and
its relationship to compensation of executive officers, and makes appropriate
recommendations concerning matters of executive compensation.
 
COMPENSATION PHILOSOPHY
 
     The Company believes that executive compensation should be closely related
to increased stockholder value. One of the Company's strengths contributing to
its successes is a strong management team, many of whom have been with the
Company for a large number of years. The Committee believes that low executive
turnover has been instrumental to the Company's success, and that the Company's
compensation program has played a major role in limiting executive turnover. The
compensation program is designed to enable the Company to attract, retain and
reward capable employees who can contribute to the continued success of the
Company, principally by linking compensation with the attainment of key business
objectives. Equity participation and a strong alignment to stockholders'
interests are key elements of the Company's compensation philosophy.
Accordingly, the Company's executive compensation program is designed to provide
competitive compensation, support the Company's strategic business goals and
reflect the Company's performance.
 
     The compensation program reflects the following principles:
 
     - Compensation should encourage increased stockholder value.
 
     - Compensation programs should support the short-and long-term strategic
       business goals and objectives of the Company.
 
     - Compensation programs should reflect and promote the Company's values and
       reward individuals for outstanding contributions toward business goals.
 
     - Compensation programs should enable the Company to attract and retain
       highly qualified professionals.
 
PAY MIX AND MEASUREMENT
 
     The Company's executive compensation is comprised of two components, base
salary and incentives, each of which is intended to serve the overall
compensation philosophy.
 
  Base Salary
 
     The Company's salary levels are intended to be consistent with competitive
pay practices and level of responsibility, with salary increases reflecting
competitive trends, the overall financial performance and resources of the
Company, general economic conditions as well as a number of factors relating to
the
 
                                      A-10
<PAGE>   36
 
particular individual, including the performance of the individual executive,
and level of experience, ability and knowledge of the job.
 
  Incentives
 
     Incentives consist of cash awards and stock options. Cash awards are paid
under the Company's incentive bonus plan to key senior and middle management
executives. Beginning with 1996, the Company adopted a Shareholder Value Added
Plan that entitles participants to receive cash bonuses based on an annual
aggregate award plus any deferred award balance from the award bank.
Contributions to the annual aggregate award and the award bank are based on a
fixed percentage of the Shareholder Value Added ("SVA") plus a fixed percentage
of the annual change in SVA. SVA is defined as the amount that Net Operating
Profit After Taxes ("NOPAT") exceeds a capital charge, which is calculated as
Capital Employed (as defined in the plan) multiplied by the associated Cost of
Capital (as defined in the plan). Each participant's share is based on a
specified percentage of their salary in relation to the other participants. For
1998, cash awards equal to 42.9%, 32.3%, 33.1%, 25.3% and 10.9% of their
respective salaries were paid to Messrs. Ammerman, Voelkert, Blackmon, Buchholz
and Smith, respectively. In addition, Mr. Smith received a bonus based on the
results of the Polymer Coil Coaters Division equal to 50.4% of his salary. Stock
options are granted from time to time to reward key employees' contributions.
 
     The Committee strongly believes that the pay program should provide
employees with an opportunity to increase their ownership and potentially gain
financially from Company stock price increases. By this approach, the best
interests of stockholders, executives and employees will be closely aligned.
Therefore, executives and other employees are eligible to receive stock options,
giving them the right to purchase shares of Common Stock of the Company at a
specified price in the future. The grant of options is based primarily on a key
employee's potential contribution to the Company's growth and profitability,
based on the Committee's discretionary evaluation. Options are granted at the
prevailing market value of the Company's Common Stock and will only have value
if the Company's stock price increases. Generally, grants of options vest over a
period of time and executives must be employed by the Company for such options
to vest.
 
  Chief Executive Officer 1998 Compensation
 
     The base salary for Robert T. Ammerman, the Company's Chief Executive
Officer, was $400,000 during the Company's fiscal year ended December 31, 1998.
Such base salary of $400,000 was increased $150,000 from Mr. Ammerman's 1997
base salary. In 1998 Mr. Ammerman also received a cash bonus of $171,716 for
services rendered in 1998, of which $155,090 was earned pursuant to the
Shareholder Value Added Plan described above and $16,626 was earned pursuant to
a similar shareholder value added plan for the Windsor Door division. The
increase in base salary for 1998 was made in recognition of the Company's 1997
performance and Mr. Ammerman's role in such performance, the increased size of
the Company as a result of the Company's acquisition of the Windsor Door
division of United Dominion Industries, Inc. and the fact that Mr. Ammerman's
salary was not increased in 1997 from his 1996 salary. Mr. Ammerman was not
granted any options in 1998 in light of the two option grants, totaling 45,000
shares, made to Mr. Ammerman in 1997. In January 1999, Mr. Ammerman was granted
options to purchase 30,000 shares of Common Stock at an exercise price of $23.50
per share. These options become exercisable in four equal annual installments on
the anniversary date of the grant.
 
     The aggregate compensation paid to Mr. Ammerman was deemed appropriate by
the Compensation Committee considering the overall performance of the Company
and Mr. Ammerman.
 
  Tax Effects
 
     Changes made in 1993 to the Code impose certain limitations on the
deductibility of executive compensation paid by public companies. In general,
under the limitations, the Company will not be able to deduct annual
compensation paid to certain executive officers in excess of $1,000,000 except
to the extent that such compensation qualifies as "performance-based
compensation" (or meets other exceptions not here relevant). Non-deductibility
would result in additional tax cost to the Company. It is possible that at least
                                      A-11
<PAGE>   37
 
some of the cash and equity-based compensation paid or payable to the Company's
executive officers will not qualify for the "performance-based compensation"
exclusion under the deduction limitation provisions of the Code. Nevertheless,
the Committee anticipates that in making compensation decisions it will give
consideration to the net cost to the Company (including, for this purpose, the
potential limitation on deductibility of executive compensation).
 
     The Compensation Committee believes that linking executive compensation to
corporate performance results in a better alignment of compensation with
corporate business goals and stockholder value. The Committee believes its
compensation practices are directly tied to stockholder returns and linked to
the achievement of annual and longer-term financial and operational results of
the Company on behalf of the Company's stockholders. In view of the Company's
performance and achievement of goals and competitive conditions, the
Compensation Committee believes that compensation levels during 1998 adequately
reflect the Company's compensation goals and policies.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     On February 18, 1993, the Company's Board of Directors established a
Compensation Committee, which currently consists of Messrs. Newhouse and
Shapiro, to recommend compensation for the Company's executives.
 
     On February 25, 1998 each of Messrs. Newhouse and Shapiro was granted an
option to purchase 1,500 shares of the Company's Common Stock pursuant to the
Directors' Option Plan. On February 25, 1999 each above-named non-employee
director was granted an option to purchase 5,000 shares of the Company's Common
Stock pursuant to the Directors' Option Plan. See "-- Compensation of
Directors."
 
     In connection with the recapitalization of the Company in January 1993, the
Company entered into a management agreement with Sterling pursuant to which
Sterling agreed to provide financial and management consulting services to the
Company for a fee of $275,000 per annum plus reimbursement of direct out-of-
pocket costs and expenses. In connection with the Company's acquisition of the
Windsor Door division of United Dominion Industries, Inc. the Company and
Sterling amended the management agreement to increase the fee thereunder to
$375,000 per annum in recognition of Sterling's increased responsibilities
resulting from the increased size of the Company following the acquisition. On
March 30, 1999, the Company and Sterling amended the management agreement to
provide for payment in full of the management fee for the remainder of the term
of the agreement simultaneously with the purchase of Shares pursuant to the
Offer. Each of Messrs. Newhouse and Selden is an officer, director and holder of
one-third of the shares of Sterling.

     The above Graph compares the performance of the Company from April 29,
1994, the date that the Company's Common Stock commenced trading on the Nasdaq
National Market, through December 31, 1998, against the performance of the
Nasdaq Market Index and the Company's Peer Group (SIC Code Index) for the same
period. The companies included in the Company's Peer Group are Butler
Manufacturing Company, Mark Solutions Inc., Miller Building Systems Inc. and NCI
Building Systems, Inc. United Dominion Industries, Inc., which was in the
Company's Peer Group last year, was not included this year because it has
disposed of all of its metal building systems and related operations.
 
SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
     Section 16(a) of the Exchange Act requires the Company's executive officers
and directors, and persons who beneficially own more than ten percent of the
Company's Common Stock, to file initial reports of ownership and reports of
changes in ownership with the SEC and the National Association of Securities
Dealers, Inc. Executive officers, directors and greater than ten percent
beneficial owners are required by SEC regulations to furnish the Company with
copies of all Section 16(a) forms they file.
 
     Based upon a review of the copies of such forms furnished to the Company
and written representations from the Company's executive officers and directors,
the Company believes that during fiscal 1998 all Section 16(a) filing
requirements applicable to its executive officers, directors and greater than
ten percent beneficial owners were complied with.

The Board of Directors
American Buildings Company
1150 State Docks Road
P.O. Box 800
Eufaula, AL 36027
 
Members of the Board:
 
     We understand that American Buildings Company (the "Company"), ABCO
Holdings Corp. ("Parent") and ABCO Acquisition Corp. ("Purchaser"), a wholly
owned subsidiary of Parent, propose to enter into an Agreement and Plan of
Merger (the "Merger Agreement") pursuant to which Purchaser will make a tender
offer (the "Offer") for all the issued and outstanding shares of common stock,
par value $.01 per share (the "Shares"), of the Company and, subsequent to the
consummation of the Offer, Purchaser will be merged with and into the Company
(the "Merger"). Each Share acquired pursuant to the Offer will be purchased for,
and each outstanding Share (other than Shares held by Parent, Purchaser, the
Company or any subsidiary of the Company) will be converted at the effective
time of the Merger into the right to receive, cash consideration of $36.00 per
Share (the "Consideration").
 
     The terms and conditions of the Offer and the Merger (collectively, the
"Transaction") are more fully set forth in the Merger Agreement.
 
     You have requested our opinion as to whether as of April 7, 1999, the
Consideration to be paid by the Purchaser in the Transaction is fair, from a
financial point of view, to the holders of the Company Common Stock.
 
     Warburg Dillon Read LLC ("WDR") has acted as financial advisor to the Board
of Directors of the Company in connection with the Transaction and will receive
a fee upon the consummation thereof. In the past, WDR and its predecessors have
provided investment banking services to the Company and received customary
compensation for the rendering of such services. In the ordinary course of
business, WDR, its successors and affiliates may trade or have traded securities
of the Company or affiliates of the Purchaser for their own accounts and,
accordingly, may at any time hold a long or short position in such securities.
 
     Our opinion does not address the Company's underlying business decision to
effect the Transaction or constitute a recommendation to any shareholder of the
Company as to how such shareholder should vote with respect to the Transaction.
At your direction, we have not been asked to, nor do we, offer any opinion as to
the material terms of the Merger Agreement or the form of the Transaction. In
rendering this opinion, we have assumed, with your consent, that the final
executed form of the Merger Agreement does not differ in any material respect
from the draft that we have examined, and that the Purchaser and the Company
will comply with all the material terms of the Merger Agreement.
 
     In arriving at our opinion, we have, among other things: (i) reviewed
certain publicly available business and historical financial information
relating to the Company, (ii) reviewed certain internal financial information
and other data relating to the business and financial prospects of the Company,
including estimates and financial forecasts prepared by management of the
Company, that were provided to us by the Company and not publicly available,
(iii) conducted discussions with members of the senior management of the
Company, (iv) reviewed publicly available financial and stock market data with
respect to certain other companies in lines of business we believe to be
generally comparable to those of the Company, (v) compared the financial terms
of the Transaction with the publicly available financial terms of certain other
transactions which we believe to be generally relevant, (vi) reviewed drafts of
the Merger Agreement, and (vii) conducted such other financial studies,
analyses, and investigations, and considered such other information as we deemed
necessary or appropriate.
 
     In connection with our review, at your direction, we have not assumed any
responsibility for independent verification for any of the information provided
to or reviewed by us for the purpose of this opinion and have, at
<PAGE>   41
 
your direction, relied on its being complete and accurate in all material
respects. In addition, at your direction we have not made or received any
independent evaluation or appraisal of any of the assets or liabilities
(contingent or otherwise) of the Company, nor have we been furnished with any
such evaluation or appraisal. In our role as financial advisor, at your
direction we have responded to expressions of interest and have not been
requested to, nor have we actively solicited, interest in a possible acquisition
of the Company. With respect to the financial forecasts and estimates referred
to above, we have assumed, at your direction, that they have been reasonably
prepared on a basis reflecting the best currently available estimates and
judgments of the management of the Company as to the future performance of the
Company. Our opinion is necessarily based on economic, monetary, market and
other conditions as in effect on, and the information made available to us as
of, the date hereof.
 
     Based upon and subject to the foregoing, it is our opinion that, as the
date hereof, the Consideration to be paid by the Purchaser to the holders of the
Company Common Stock in the Transaction is fair, from a financial point of view,
to the holders of the Company Common Stock.
 
                                          Very truly yours,
 
                                          WARBURG DILLON READ LLC

Dear Stockholder:
 
     We are pleased to inform you that on April 7, 1999, American Buildings
Company (the "Company") entered into an Agreement and Plan of Merger (the
"Merger Agreement") with ABCO Holdings Corp. ("Parent") and its wholly owned
subsidiary, ABCO Acquisition Corp. ("Purchaser"), which provides for the
acquisition of the Company by Onex Corporation, an Ontario, Canada corporation
which indirectly owns Parent and Purchaser. Under the terms of the Merger
Agreement, Purchaser today commenced a tender offer (the "Offer") to purchase
all of the Company's outstanding shares of common stock (the "Shares") for
$36.00 per Share in cash. The Merger Agreement further provides that, following
consummation of the Offer, Purchaser will be merged with and into the Company
(the "Merger") and all Shares not purchased in the Offer (other than those held
by stockholders who perfect their appraisal rights, Shares owned by Parent or
Purchaser and Shares owned by the Company or any subsidiary of the Company) will
be converted in the Merger into the right to receive $36.00 per Share in cash.
 
     YOUR BOARD OF DIRECTORS HAS UNANIMOUSLY (WITH ONE DIRECTOR NOT PRESENT)
APPROVED THE MERGER AGREEMENT, THE OFFER AND THE MERGER AND DEEMED THEM
ADVISABLE, AND HAS DETERMINED THAT THE OFFER AND THE MERGER ARE FAIR TO AND IN
THE BEST INTERESTS OF THE COMPANY'S STOCKHOLDERS. THE BOARD UNANIMOUSLY (WITH
ONE DIRECTOR NOT PRESENT) RECOMMENDS THAT THE COMPANY'S STOCKHOLDERS ACCEPT THE
OFFER AND TENDER THEIR SHARES IN THE OFFER.
 
     In arriving at its recommendation, the Board of Directors gave careful
consideration to a number of factors described in the attached Schedule 14D-9
that is being filed today with the Securities and Exchange Commission,
including, among other things, the opinion of Warburg Dillon Read LLC, the
Company's financial advisor, to the effect that, as of April 7, 1999, the $36.00
in cash to be received by the Company's stockholders in the Offer and the Merger
is fair from a financial point of view to the Company's stockholders. The full
text of the written opinion of Warburg Dillon Read LLC, dated April 7, 1999,
which sets forth the assumptions made, matters considered and limitations on the
review undertaken in connection with the opinion, is attached to the Schedule
14D-9 as Annex B. All stockholders are urged to, and should, read the opinion of
Warburg Dillon Read LLC carefully in its entirety.
 
     In addition to the attached Schedule 14D-9 relating to the Offer, also
enclosed is the Offer to Purchase, dated April 13, 1999, of Parent and
Purchaser, together with related materials, including a Letter of Transmittal to
be used for tendering your Shares. These documents set forth the terms and
conditions of the Offer and the Merger and provide instructions as to how to
tender your Shares. We urge you to read the enclosed materials carefully.
 
     On behalf of the Board of Directors and management of the Company, we thank
you for the support you have given to the Company.
 
                                          Very truly yours,
                                          /s/ William L. Selden
