ITEM 1. SECURITY AND SUBJECT COMPANY.
 
    The name of the subject company is ABT Building Products Corporation, a
Delaware corporation (the "Company"). The address of the principal executive
offices of the Company is One Neenah Center, Suite 600, Neenah, Wisconsin
54956-3070. The title of the class of equity securities to which this
Solicitation/Recommendation Statement on Schedule 14D-9 (this "Schedule 14D-9")
relates is the common stock, par value $.01 per share, of the Company (the
"Common Stock").
 
ITEM 2. TENDER OFFER OF THE BIDDER.
 
    This Statement relates to the tender offer (the "Offer") by Striper
Acquisition, Inc., a Delaware corporation ("Offeror") and a direct wholly owned
subsidiary of Louisiana-Pacific Corporation, a Delaware corporation ("Parent"),
to purchase all outstanding shares of Common Stock at a price per share of
$15.00, net to the seller in cash, without interest (such price, the "Offer
Consideration"), upon the terms and subject to the conditions set forth in the
Offer to Purchase, dated January 25, 1999 (the "Offer to Purchase"), and the
related Letter of Transmittal (which together and with any amendments or
supplements hereto or thereto, collectively constitute the "Offer").
 
    The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of January 19, 1999, among the Company, Parent and Offeror (the "Merger
Agreement"). The Merger Agreement provides, among other things, for the
commencement of the Offer by Purchaser and further provides that after the
purchase of the Common Stock pursuant to the Offer, subject to the satisfaction
or waiver of the conditions set forth in the Merger Agreement, the Offeror will
be merged with and into the Company (the "Merger") and the Company will continue
as the surviving corporation (the "Surviving Corporation") and a wholly owned
subsidiary of Parent. A copy of the Merger Agreement is filed with the
Securities and Exchange Commission (the "SEC") as Exhibit 1 to this Schedule
14D-9 and is incorporated herein by reference in its entirety.
 
    In the Merger, each share of Common Stock (excluding shares of Common Stock
owned by the Company or any of its subsidiaries or by Parent, the Offeror or any
other subsidiary of Parent or the Offeror, and shares of Common Stock owned by
stockholders who have properly exercised their appraisal rights under Delaware
law) issued and outstanding immediately prior to the effective time of the
Merger (the "Effective Time") will be converted at the Effective Time into the
right to receive the Offer Consideration, in cash, without interest and less any
required withholding taxes (the "Merger Consideration").
 
    As a condition and inducement to Parent and the Offeror to enter into the
Merger Agreement, concurrently with the execution and delivery of the Merger
Agreement, Parent and the Offeror have entered into a Stockholder Agreement,
dated as of January 19, 1999 (the "Stockholder Agreement"), with certain
stockholders of the Company (the "Principal Stockholders") who beneficially own
in the aggregate 4,952,554 shares of Common Stock (and one of whom holds options
to purchase an additional 710,000 shares of Common Stock). Pursuant to the
Stockholder Agreement, such stockholders have agreed, among other things, to
validly tender (and not withdraw) all of such shares, representing approximately
46.4% of the outstanding shares of Common Stock pursuant to the Offer made by
Parent and the Offeror. Please refer to the section in this Schedule 14D-9
entitled "Identity and Background--Arrangements with Parent, Offeror and their
respective Executive Officers, Directors or Affiliates--The Stockholder
Agreement." A copy of the Stockholder Agreement is filed with the SEC as Exhibit
2 to this Schedule 14D-9 and is incorporated herein by reference in its
entirety.
 
    As set forth in the Tender Offer Statement on Schedule 14D-1 of the Offeror
enclosed herewith, the address of the principal executive offices of Offeror and
Parent is 111 S.W. Fifth Avenue, Portland, Oregon 97204.

ITEM 3. IDENTITY AND BACKGROUND.
 
    (A) NAME AND BUSINESS ADDRESS OF PERSON FILING THIS STATEMENT.
 
    The name and business address of the Company, which is the person filing
this Schedule 14D-9, are set forth in Item 1 above.
 
    (B)(1)  ARRANGEMENTS WITH EXECUTIVE OFFICERS, DIRECTORS OR AFFILIATES OF THE
       COMPANY.
 
    Certain contracts, agreements, arrangements and understandings between the
Company and certain of its executive officers, directors and affiliates,
together with certain employee benefit plans of the Company available to them,
are described on pages 3 through 9 of the Company's Proxy Statement, dated March
30, 1998 (the "1998 Proxy Statement"), relating to the Company's 1998 Annual
Meeting of the Stockholders. A copy of the relevant portions of the 1998 Proxy
Statement are filed with the SEC as Exhibit 3 to this Schedule 14D-9 and are
incorporated herein by reference.
 
    In connection with the Merger Agreement, the Board of Directors of the
Company (the "Board") amended the Company's by-laws to provide that newly
created directorships resulting from an increase in the number of Directors and
vacancies occurring on the Board for other reasons may be filled by a vote of a
majority of the directors remaining on the Board of Directors. A copy of the
amendment to the Company's by-laws is filed with the SEC as Exhibit 4 to this
Schedule 14D-9 and is incorporated herein by reference in its entirety.
 
    In addition, the Company entered into a Termination of Fee Agreement with
Kohlberg & Co., L.P., terminating the Fee Agreement, dated as of October 20,
1992, between the Company and Kohlberg & Co., L.P., effective upon the
consummation of the Offer. A copy of the Termination of Fee Agreement is filed
with the SEC as Exhibit 5 to this Schedule 14D-9 and is incorporated herein by
reference in its entirety.
 
    The Company also adopted an Executive Severance Pay Plan (the "Plan"), a
copy of which is filed with the SEC as Exhibit 6 to this Schedule 14D-9 and is
incorporated herein by reference, and entered into a severance arrangement with
Mr. George T. Brophy, its Chairman of the Board and Chief Executive Officer (the
"Severance Arrangement"), a copy of which is filed with the SEC as Exhibit 7 to
this Schedule 14D-9 and is incorporated herein by reference. The Plan covers
certain executive officers of the Company having one or more full years of
service and who are involuntarily terminated due to (i) a job elimination, (ii)
a reduction in force, (iii) any reason other than for cause within one year
following a change of control, or (iv) voluntary termination of their employment
with the Company within the period beginning 60 days and ending 90 days after
the occurrence of a change of control, and provides that such officers' options
will not be forfeited and will immediately vest upon any such termination. Such
officers will also be entitled to receive their monthly salary for 18 months
commencing on the date of their termination, a pro-rata bonus payment (through
the date of their termination) of their bonus entitlement for the year of
termination payable in the following January, an additional bonus payment
equaling the average of the prior three years' bonuses payable at the end of the
18 months following their termination, and various other benefits. Under the
Severance Arrangement, Mr. Brophy will be entitled to certain benefits,
including receiving a lump sum severance payment of $1,777,368 in full
satisfaction of all rights to severance or other post-termination payments (but
excluding his rights with respect to any stock or stock options that he holds)
to which he would be entitled upon a termination of his employment with the
Company without cause or due to a voluntary termination within the period
beginning 60 days and ending 90 days after a change of control. In addition, Mr.
Brophy's unvested stock options will immediately vest and become exercisable
upon a change of control. The Plan and the Severance Arrangement replaced and
superseded prior severance arrangements or programs sponsored by the Company for
the benefit of Mr. Brophy and the officers named in the Plan.

    (B) (2) ARRANGEMENTS WITH PARENT, OFFEROR AND THEIR RESPECTIVE EXECUTIVE
       OFFICERS, DIRECTORS OR AFFILIATES.
 
    The Company has entered into the Merger Agreement with Parent and the
Offeror, and Parent and the Offeror have entered into the Stockholder Agreement
with the Principal Stockholders.
 
THE MERGER AGREEMENT
 
    The following is a summary of the material terms of the Merger Agreement.
This summary is not a complete description of the terms and conditions of the
Merger Agreement and is qualified in its entirety by reference to the complete
text of the Merger Agreement, which is incorporated by reference and a copy of
which is filed with the SEC as Exhibit 1 to this Schedule 14D-9.
 
    THE OFFER.  The Merger Agreement provides for the commencement of the Offer,
Without the prior written consent of the Company, the Offeror has agreed not to
(and the Parent has agreed to cause the Offeror not to) (i) decrease or change
the form of the Offer Consideration or decrease the number of shares of Common
Stock sought pursuant to the Offer, (ii) amend any term of the Offer in any
manner adverse to holders of shares of Common Stock, (iii) change the conditions
to the Offer, (iv) impose additional conditions to the Offer, (v) waive the
condition that there shall be validly tendered and not withdrawn prior to the
time the Offer expires a number of shares of Common Stock (together with any
shares of Common Stock then owned by Parent or any of its subsidiaries) which
constitutes a majority of the shares of Common Stock outstanding on a
fully-diluted basis on the date of purchase, or (vi) extend the expiration date
of the Offer beyond the initial expiration date of the Offer (except that the
Offeror may, without the consent of the Company, (a) extend the Offer if, at the
then scheduled expiration date of the Offer any of the conditions to the
Offeror's obligation to purchase shares of Common Stock in the Offer is not
satisfied, until such time as such condition is satisfied or waived, and (b)
extend the Offer for any period required by any rule, regulation, interpretation
or position of the SEC or the staff thereof); provided, however, that, except as
set forth above and subject to applicable legal requirements, the Offeror may
amend the Offer or waive any condition to the Offer in its sole discretion. The
Merger Agreement also provides that the Parent shall provide the Offeror on a
timely basis funds necessary to purchase any shares of Common Stock that the
Offeror becomes obligated to purchase pursuant to the Merger and the Parent
shall be liable on a direct and primary basis for the Offeror's obligations
under the Merger Agreement.
 
    BOARD REPRESENTATION.  The Merger Agreement provides that promptly upon the
purchase by Offeror pursuant to the Offer of such number of shares of Common
Stock (together with any shares of Common Stock then owned by Parent or any of
its subsidiaries) which represents a majority of the outstanding shares of
Common Stock (on a fully diluted basis) on the date of purchase, and from time
to time thereafter, (i) Parent will be entitled to designate such number of
directors, rounded up to the next whole number as will give Parent
representation on the Board equal to the product of (x) the number of directors
on the Board (giving effect to any increase in the number of directors pursuant
to the Merger Agreement) and (y) the percentage that such number of shares of
Common Stock so purchased (together with any shares of Common Stock then owned
by Parent or any of its subsidiaries), bears to the aggregate number of shares
of Common Stock outstanding on the date of purchase (such number being the
"Board Percentage"), and (ii) the Company will, upon request by Parent, promptly
cause Parent's designees constituting the Board Percentage to be elected to the
Board by (x) increasing the size of the Board or (y) using reasonable efforts to
secure the resignations of such number of directors as is necessary to enable
Parent's designees to be elected to the Board and will use its best efforts to
cause Parent's designees promptly to be so elected, subject in all instances to
compliance with Section 14(f) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), and Rule 14f-1 promulgated thereunder. Following the
election or appointment of Parent's designees pursuant to the Merger Agreement
and prior to the Effective Time, any amendment or termination of the Merger
Agreement, waiver of the obligations or other acts of Parent or the Offeror or
waiver of
 
                                       4
<PAGE>
the Company's rights thereunder will require the concurrence of a majority of
the Continuing Directors (defined as those directors of the Company then in
office who were directors of the Company on the date of the Merger Agreement and
who voted to approve the Merger Agreement and such additional directors of the
Company, if any, who are not affiliated with Parent, the Offeror or any of their
affiliates and who were designated as "Continuing Directors" by a majority of
the directors who were Continuing Directors at the time of such designation).
The Company is today mailing to the stockholders of the Company a copy of an
Information Statement prepared in accordance with Rule 14f-1 promulgated under
the Exchange Act, relating to the possible designation by Parent, pursuant to
the Merger Agreement, of certain persons to be appointed to the Board otherwise
than at a meeting of the stockholders of the Company.
 
    CONSIDERATION TO BE PAID IN THE MERGER.  The Merger Agreement provides that,
on the terms and subject to the conditions set forth in the Merger Agreement and
in accordance with the General Corporation Law of the State of Delaware (the
"DGCL"), the Offeror will be merged with and into the Company at the Effective
Time. In the Merger, each share of Common Stock issued and outstanding
immediately prior to the Effective Time (excluding shares of Common Stock owned
by the Company or any of its subsidiaries or shares of Common Stock owned by
Parent, the Offeror or any other subsidiary of Parent and Dissenting Shares (as
defined in the Merger Agreement)) will be converted into the right to receive
the Offer Consideration, payable to the holder thereof without any interest
thereon, less any required withholding taxes, upon surrender and exchange of a
certificate representing such shares of Common Stock. Each share of the capital
stock of the Offeror issued and outstanding immediately prior to the Effective
Time will be converted into and become one fully paid and nonassessable share of
Common Stock, par value $0.01 per share, of the Surviving Corporation, which
will thereupon become a wholly owned subsidiary of Parent. Each share of Common
Stock and all other shares of capital stock of the Company that are owned by the
Company or any subsidiary of the Company and all shares of Common Stock owned by
Parent, the Offeror or any other subsidiary of Parent will be canceled and
retired and will cease to exist and no consideration will be delivered or
deliverable in exchange therefor. The Merger will become effective upon the
filing of a certificate of merger with the Secretary of State of the State of
Delaware or at such time thereafter as is provided in the certificate of merger.
 
    COMPANY STOCK OPTIONS.  The Merger Agreement provides that, at the Effective
Time, each then-outstanding option to purchase shares of Common Stock
(collectively, the "Options") under the Company's Amended and Restated Stock
Option Plan, 1994 Director Stock Option Plan, 1994 Employee Stock Option Plan
and new employee compensation policy (collectively, the "Stock Option Plans"),
whether or not then exercisable, will, in settlement thereof, receive for each
share of Common Stock subject to such Option an amount (subject to any
applicable withholding tax) in cash equal to the difference between the Offer
Consideration and the per share exercise price of such Option to the extent such
difference is a positive number (such amount being hereinafter referred to as,
the "Option Consideration"); PROVIDED, HOWEVER, that with respect to any person
subject to Section 16(a) of the Exchange Act, any such amount will be paid as
soon as practicable after the first date payment can be made without liability
to such person under Section 16(b) of the Exchange Act. Upon receipt of the
Option Consideration therefor, each Option will be canceled. The surrender of an
Option to the Company in exchange for the Option Consideration will be deemed a
release of any and all rights the holder had or may have had in respect of such
Option.
 
    The Company has agreed to use its reasonable best efforts to obtain all
necessary consents or releases from holders of Options under the Stock Option
Plans and take all such other lawful action as may be necessary to give effect
to the transactions contemplated by the Merger Agreement. Except as otherwise
agreed to by the parties, (i) the Stock Option Plans will terminate as of the
Effective Time and the provisions in any other plan, program or arrangement
providing for the issuance or grant of any other interest in respect of the
capital stock of the Company or any subsidiary thereof will be
 
                                       5
<PAGE>
canceled as of the Effective Time and (ii) the Company will use its reasonable
best efforts to assure that following the Effective Time no participant in the
Stock Option Plans or other plans, programs or arrangements will have any right
thereunder to acquire any equity securities of the Company, the Surviving
Corporation or any subsidiary thereof and to terminate all such plans.
 
    STOCKHOLDER MEETING.  The Merger Agreement provides that the Company will,
as soon as practicable following the acceptance for payment of and payment for
the shares of Common Stock by the Offeror in the Offer, if required by
applicable law to consummate the Merger, duly call, give notice of, convene and
hold a meeting of its stockholders for the purpose of considering and voting
upon the Merger Agreement. In connection with such meeting, if required by
applicable law to consummate the Merger, the Company, in consultation with
Parent, will prepare and file with the SEC a proxy statement, together with any
supplement or amendment thereto (the "Proxy Statement"). The Company has agreed
to use its reasonable efforts to respond to all SEC comments with respect to the
Proxy Statement and, subject to compliance with the SEC's rules and regulations,
to cause such proxy statement to be mailed to the stockholders at the earliest
practicable date.
 
    If the Offeror, or any other wholly owned subsidiary of Parent, acquires at
least 90% of the outstanding shares of Common Stock in the Offer, at the request
of the Offeror, all parties to the Merger Agreement will take all necessary
actions to cause the Merger to become effective as soon as practicable after the
expiration of the Offer, without a meeting of the stockholders, in accordance
with the provisions of Section 253 of the DGCL.
 
    REPRESENTATIONS AND WARRANTIES.  The Merger Agreement contains various
representations and warranties of the parties. These include representations and
warranties by the Company with respect to: (i) organization, standing and

the consent or approval of any governmental entity (including without limitation
under the HSR Act). The Merger Agreement also provides that in case at any time
after the Effective Time any further action is necessary or desirable to carry
out the Merger Agreement, the proper officers and directors of each party to the
Merger Agreement will use their reasonable best efforts to take such action.
 
    EMPLOYEE BENEFIT MATTERS.  The Merger Agreement provides that, from and
after the Effective Time, Parent will, and will cause its subsidiaries
(including the Surviving Corporation) to, honor and provide for payment of all
accrued obligations and benefits, including but not limited to any bonus
payments earned in respect of fiscal 1998 but not yet paid, under all employee
benefit plans of the Company and employment or severance agreements between the
Company and any persons who are or had been employees of the Company or any of
its subsidiaries at or prior to the Effective Time (the "Covered Employees"),
all in accordance with their respective terms.
 
    The Merger Agreement further provides that, from and after the Effective
Time, Parent will, and will cause its subsidiaries (including the Surviving
Corporation) to, provide Covered Employees who remain in the employ of Parent or
any such subsidiary employee benefits that are reasonably comparable to the
employee benefits provided to similarly situated employees of Parent or any such
subsidiary who are not Covered Employees. The Merger Agreement also provides
that, to the extent Covered Employees are included in any benefit plan of Parent
or its subsidiaries, Parent agrees that the Covered Employees will receive
credit under such plan for service prior to the Effective Time with the Company
and its subsidiaries to the same extent such service was counted under similar
employee benefit plans of the Company for purposes of eligibility, vesting,
eligibility for retirement (but not for benefit accrual) and, with respect to
vacation, disability and severance, benefit accrual. The Merger Agreement also
provides that, to the extent that Covered Employees are included in any medical,
dental or health plan other than the plan or plans they participated in at the
Effective Time, no such plans will include pre-existing condition exclusions,
except to the extent that such exclusions were applicable under the similar the
Company employee benefit plan at the Effective Time, and all such plans will
provide credit for any deductibles and co-payments applied or made with respect
to each Covered Employee in the calendar year of the change.
 
    Notwithstanding anything in the Merger Agreement to the contrary, from and
after the Effective Time, the Surviving Corporation will have sole discretion
over the hiring, promotion, retention, firing and other terms and conditions of
the employment of employees of the Surviving Corporation. Except as otherwise
provided in the Merger Agreement, nothing in the Merger Agreement prevents
Parent or
 
                                       8
<PAGE>
the Surviving Corporation from amending or terminating any Company benefit plan
in accordance with its terms.
 
    NO SOLICITATION.  The Merger Agreement provides that, during the period from
and including the date of the Merger Agreement to the Effective Time, the
Company will not, and will not authorize or permit any of its subsidiaries, or
any of its or their affiliates, officers, directors, employees, agents or
representatives (including without limitation any investment banker, financial
advisor, attorney or accountant retained by the Company or any of its
subsidiaries), to, directly or indirectly, initiate, solicit, or encourage
(including by way of furnishing information or assistance), or take any other
action to facilitate, any Acquisition Proposal (as defined below), or enter into
or maintain or continue discussions or negotiations with any person in
furtherance of, or approve, agree to, endorse or recommend, any Acquisition
Proposal; except that nothing in the Merger Agreement will prohibit the Board,
prior to the time at which the Merger Agreement is adopted by the stockholders
of the Company, from furnishing information to, or entering into, maintaining or
continuing discussions or negotiations with, any person that makes a bona fide
written Acquisition Proposal after the date of the Merger Agreement under
circumstances not involving any breach of the provisions of the Merger
Agreement, if, and to the extent that, (i) the Board, after consultation with
and based upon the advice of independent legal counsel, determines in good faith
that the failure to take such action would constitute a breach by the Board of
its fiduciary duties to the stockholders of the Company under applicable law,
and (ii) prior to furnishing any non-public information to such person, the
Company receives from such person an executed confidentiality agreement with
provisions no less favorable to the Company than the letter agreement relating
to the furnishing of confidential information of the Company to Parent. The
Merger Agreement further provides that the Company will promptly (and, in any
event within 24 hours) notify Parent after receipt of any Acquisition Proposal
or any request for information relating to the Company or its subsidiaries or
for access to the properties, books or records of the Company or any of its
subsidiaries by any person who has informed the Company that such person is
considering making, or has made, an Acquisition Proposal (which notice will
identify the person making, or considering making, such Acquisition Proposal and
will set forth the material terms of any Acquisition Proposal received), and
that the Company will keep Parent informed in reasonable detail of the terms,
status and other pertinent details of any such Acquisition Proposal.
 
    The Merger Agreement further provides that during the period from and
including the date of the Merger Agreement to and including the Effective Time,
neither the Board nor any committee thereof will withdraw or modify, or propose
publicly to withdraw or modify, in a manner adverse to Parent or the Offeror,
the approval of the Merger Agreement or the transactions contemplated thereby or
the recommendation of the Board in favor of the Offer and the Merger, except
that nothing contained in the Merger Agreement will (i) prohibit the Board from
withdrawing or modifying such recommendation following the receipt by the
Company after the date of the Merger Agreement, under circumstances not
involving any breach of the provisions described in the immediately preceding
paragraph, of an Acquisition Proposal if, and to the extent that, the Board,
after consultation with and based upon the advice of independent legal counsel,
determines in good faith that the failure to take such action would result in a
breach by the Board of its fiduciary duties to the stockholders of the Company
under applicable law or (ii) prohibit the Board from, to the extent applicable,
complying with Rule 14e-2 promulgated under the Exchange Act with regard to an
Acquisition Proposal. Subject to the Company's right to terminate the Merger
Agreement under certain circumstances described below, no such action taken by
the Board will permit the Company to enter into any agreement providing for any
transaction contemplated by an Acquisition Proposal for as long as the Merger
Agreement remains in effect.
 
    For purposes of the Merger Agreement, "Acquisition Proposal" means an
inquiry, offer, proposal or indication of interest regarding any of the
following (other than the transactions contemplated by the Merger Agreement, the
Stockholder Agreement or the Fiber Cement Agreement) involving the
 
                                       9
<PAGE>
Company: (i) any merger, consolidation, share exchange, recapitalization,
business combination, or other similar transaction; (ii) any sale, lease,
exchange, mortgage, pledge, transfer or other disposition of all or
substantially all of the assets of the Company and its subsidiaries, taken as a
whole, in a single transaction or series of related transactions; (iii) any
tender offer or exchange offer or other acquisition of 20% or more of the
outstanding shares of capital stock of the Company or the filing of a
registration statement under the Securities Act of 1933, as amended (the
"Securities Act"), in connection therewith; or (iv) any public announcement of a
proposal, plan or intention to do any of the foregoing or any agreement to
engage in any of the foregoing.
 
    FEES AND EXPENSES.  The Merger Agreement provides that whether or not the
Merger is consummated, each party will pay its own expenses incident to
preparing for, entering into and carrying out the Merger Agreement and the
consummation of the transactions contemplated thereby.
 
    INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE.  The Merger Agreement
provides that, for a period of six years after the Effective Time, the
provisions with respect to indemnification set forth in the certificate of
incorporation and bylaws of the Offeror will not be amended, repealed or
otherwise modified in any manner that would adversely affect the rights
thereunder of individuals who at any time prior to the Effective Time were
directors or officers of the Company in respect of actions or omissions
occurring at or prior to the Effective Time (including without limitation the
transactions contemplated by the Merger Agreement), unless such modification is
required by law.
 
    The Merger Agreement also provides that from and after the Effective Time,
Parent will, or will cause the Surviving Corporation to, indemnify, defend and
hold harmless each person who is now, or has been at any time prior to the date
thereof or who becomes prior to the Effective Time, an officer or director of
the Company (the "Indemnified Parties") against all losses, claims, damages,
costs, expenses (including reasonable attorneys' fees and expenses), liabilities
or judgments or amounts that are paid in settlement with the approval of the
indemnifying party (which approval will not be unreasonably withheld) incurred
in connection with any threatened or actual action, suit or proceeding based in
whole or in part on or arising in whole or in part out of the fact that such
person is or was a director or officer of the Company (the "Indemnified
Liabilities"), including all Indemnified Liabilities based in whole or in part
on, or arising in whole or in part out of, the Merger Agreement or the
transactions contemplated thereby, in each case, to the full extent that a
corporation is permitted under the DGCL to indemnify its own directors or
officers, as the case may be (and will pay expenses in advance of the final
disposition of any such action, suit or proceeding to each Indemnified Party to
the full extent permitted by the DGCL, upon receipt of an undertaking by or on
behalf of such Indemnified Party to repay such amount if it will ultimately be
determined that such person is not entitled to be so indemnified). The foregoing
rights to indemnification under the Merger Agreement will continue in full force
and effect for a period of four years from the Effective Time; provided,
however, that all rights to indemnification in respect of any Indemnified
Liabilities asserted or made within such period will continue until the
disposition of such Indemnified Liabilities.
 
    The Merger Agreement provides that, for a period commencing at the Effective
Time and expiring on the sixth anniversary of the Effective Time, Parent will
cause to be maintained in effect policies of directors' and officers' liability
insurance, for the benefit of those persons who are covered by the Company's
directors' and officers' liability insurance policies at the Effective Time,
providing coverage with respect to matters occurring prior to the Effective Time
that is at least equal to the coverage provided under the Company's current
directors' and officers' liability insurance policies, to the extent that such
liability insurance can be maintained at an annual cost to Parent not greater
than $350,000. The Merger Agreement further provides that if such insurance
cannot be so maintained at such cost, Parent will maintain as much of such
insurance as can be so maintained at a cost equal to $350,000.

    CONDITIONS TO THE OFFER.  Notwithstanding any other provision of the Offer,
the Offeror will not be required to accept for payment or, subject to any

shares of Common Stock tendered, and may postpone the acceptance for payment or,
subject to the restrictions referred to above, payment for any shares of Common

Stock outstanding (excluding shares of Common Stock held as treasury stock by

Common Stock the Company is then required to issue pursuant to obligations
outstanding at that date under employee stock option or other benefit plans or

       injunction or other order which is in effect and which (l) materially
       restricts, prevents or prohibits consummation of the transactions
       contemplated by the Merger Agreement, including the Offer or the Merger,
       (2) prohibits or limits materially the ownership or operation by Parent
       or any of its subsidiaries of all or any material portion of the business

       separate all or any material portion of the business or assets of the
       Company and its subsidiaries taken as a whole, or (3) imposes material

       the Merger Agreement and the transactions contemplated thereby;

       Merger Agreement (without giving effect to the materiality qualifications
       contained therein) will not be true and correct as of the expiration date
       of the Offer (as the same may be extended from time to time) as though
       made on and as of such date (except for representations and warranties
       made as of a specified date, which need be true and correct only as of
       the specified date), except for any breach or breaches which,
       individually or in the aggregate, would not reasonably be expected to
       have a material adverse effect on (i) the ability of the Company to
       perform its obligations under the Merger Agreement or to consummate the
       transactions contemplated thereby or (ii) the assets, liabilities (actual
       or contingent), financial condition, results of

       fifteen days after actual receipt by it of written notice from the
       Offeror setting forth in detail the nature of such failure or (ii) the
       expiration date of the Offer;
 
    (E) there will have occurred any material adverse change, or any development

be waived by the Offeror, in whole or in part, from time to time in its sole
discretion, except as otherwise provided in the Merger Agreement. The failure by

right and may be asserted at any time and from time to time.
 
                                       12
<PAGE>
    CONDITIONS TO THE MERGER.  Pursuant to the Merger Agreement, the obligation
of each party to effect the Merger is subject to the satisfaction or written
waiver prior to the Closing Date, of the following conditions: (i) Offeror will
have accepted for payment and paid for all shares of Common Stock validly
tendered in the Offer and not withdrawn, provided, however, that, neither Parent
nor the Offeror may invoke this condition if the Offeror has failed to purchase
Shares so tendered and not withdrawn in violation of the terms of the Merger
Agreement or the Offer; (ii) the Merger Agreement will have been adopted by the
affirmative vote of the holders of the requisite number of shares of capital
stock of the Company if such vote is required pursuant to the Company's
certificate of incorporation, the DGCL or by applicable law; (iii) no temporary
restraining order, preliminary or permanent injunction or other order issued by
any court of competent jurisdiction or other legal restraint or prohibition
preventing the consummation of the Merger will be in effect; provided, however,
that prior to invoking this condition the party so invoking this condition will
have complied with its obligations under the Merger Agreement relating to the
taking of actions necessary for the consummation of the Merger; and (iv) all
necessary waiting periods under the HSR Act applicable to the Merger will have
expired or been earlier terminated.
 
    TERMINATION.  The Merger Agreement may be terminated and the transactions
contemplated therein may be abandoned at any time prior to the Effective Time,
notwithstanding the adoption of the Merger Agreement by the stockholders of the
Company, in any one of the following circumstances: (i) by mutual written
consent duly authorized by the Boards of Parent and the Company; (ii) by Parent
or the Company if shares of Common Stock have not been purchased by the Offeror
pursuant of the Offer on or before April 30, 1999, other than as a result of any
material breach of any provision of the Merger Agreement by the party seeking to
effect such termination; (iii) by Parent or the Company if, as a result of the
failure of any of the conditions to the Offer under the Merger Agreement
(described above in "Conditions to the Offer") the Offer will have expired or
Offeror will have terminated the Offer in accordance with the terms and
conditions thereof without any shares of Common Stock being purchased by the
Offeror thereunder; provided, however, that the right to terminate the Merger
Agreement pursuant to this provision will not be available to any party whose
breach of or failure to fulfill its obligations under the Merger Agreement
resulted in the failure of any such condition; (iv) by Parent or the Company, if
any court of competent jurisdiction or other governmental entity will have
issued an order, decree or ruling or taken any other action permanently
enjoining, restraining or otherwise prohibiting the Merger or the acceptance for
payment of, or payment for, the shares pursuant to the Offer and such order,
decree or ruling or other action will have become final and nonappealable,
provided that the party seeking to terminate this Agreement will have used its
reasonable best efforts to remove or lift such order, decree or ruling; (v) by
Parent if the Board or any committee thereof will have (A) withdrawn or modified
in a manner adverse to Parent or the Offeror, or publicly taken a position
materially inconsistent with, its approval or recommendation of the Merger
Agreement, the Offer, the Merger or the other transactions contemplated thereby,
(B) approved, endorsed or recommended to its stockholders an Acquisition
Proposal, or (C) resolved or publicly disclosed any intention to do any of the
foregoing; (vi) by the Company, following the receipt by the Company after the
date hereof, under circumstances not involving any breach of the obligations of
the Company described under the caption "No Solicitation" above, of a bona fide
written Acquisition Proposal, if the Board, after consultation with and based
upon the advice of independent legal counsel, will have determined in good faith
that the failure to terminate the Merger Agreement would constitute a breach by
the Board of its fiduciary duties to the Company's stockholders under applicable
law; provided that (A) the Company has complied with specified provisions of the
Merger Agreement, including specified notice provisions, (B) the Company enters
into a definitive agreement providing for the transactions contemplated by such
Acquisition Proposal immediately following such termination, and (C) such
termination will not be effective until the Company will have paid to Parent the
Fee (as defined below) in accordance with provisions of the Merger Agreement; or
(vii) by the Company if the Offeror or Parent will have (A) failed to commence
the Offer within five business days after the public
 
                                       13
<PAGE>
announcement by Parent and the Company of the Merger Agreement, (B) failed to
pay for the shares of Common Stock pursuant to the Offer in accordance with the
Merger Agreement, or (C) breached in any material respect any of their
respective representations, warranties, covenants or other agreements contained
in the Merger Agreement, which breach described in this clause (C) is incapable
of being cured or has not been cured within 20 days after the giving of written
notice to Parent or the Offeror, as applicable, except such breaches described
in this clause (C) as individually or in the aggregate would not reasonably be
expected to materially and adversely affect the ability of Parent or the Offeror
to complete the Offer or the Merger on the terms and subject to the conditions
of the Merger Agreement. If the Merger Agreement is terminated pursuant to
clause (v) or (vi) above, the Company will pay Parent a fee in the amount of
$5,000,000 (the "Fee"), which amount will be payable in immediately available
funds (x) promptly (and in any event within three business days) after such
termination, in the case of termination under the circumstances described in
clause (v) above or (y) prior to or concurrently with such termination, in the
case of termination under the circumstances described in clause (vi) above.
 
    AMENDMENT.  Subject to any applicable provisions of the DGCL, at any time
prior to the Effective Time, the parties to the Merger Agreement may modify or
amend the Merger Agreement by written agreement executed and delivered by duly
authorized officers of the respective parties. However, after the adoption of
the Merger Agreement at the meeting of the stockholders, no amendment will be
made which would reduce the amount or change the type of consideration into
which each share of Common Stock will be converted upon consummation of the
Merger. The Merger Agreement may not be modified or amended except by written
agreement executed and delivered by duly authorized officers of each of the
respective parties.
 
    ASSIGNMENT.  Neither the Merger Agreement nor any of the rights, interests
or obligations thereunder may be assigned or delegated, in whole or in part, by
operation of law or otherwise by any of the parties thereto without the prior
written consent of the other parties, and any such assignment without such prior
written consent will be null and void, except that Parent and/or the Offeror may
assign the Merger Agreement to any direct or indirect wholly owned subsidiary of
Parent without the prior consent of the Company, provided that the Parent and/or
the Offeror, as the case may be, will remain liable for all of its obligations
under the Merger Agreement. Subject to the immediately preceding sentence, the
Merger Agreement will be binding upon, inure to the benefit of, and be
enforceable by, the parties and their respective successors and assigns.
 
    TIMING.  The exact timing and details for the Merger will depend upon legal
requirements and a variety of other factors, including the number of Shares
acquired by Offeror pursuant to the Offer. Although the Offeror has agreed to
cause the Merger to be consummated on the terms set forth above, there can be no
assurance as to the timing of the Merger.
 
THE STOCKHOLDER AGREEMENT
 
    The following is a summary of certain material provisions of the Stockholder
Agreement. This summary is not a complete description of the terms and
conditions of the Stockholder Agreement and is qualified in its entirety by
reference to the complete text of the Stockholder Agreement, which is
incorporated by reference and a copy of which is filed with the SEC as Exhibit 2
to this Schedule 14D-9.
 
    TENDER OF SHARES.  Each Principal Stockholder has agreed to cause to be
validly tendered (and not withdrawn) pursuant to and in accordance with the
terms of the Offer, not later than the tenth business day after commencement of
the Offer, all shares of Common Stock beneficially owned by such Principal
Stockholders (such shares, together with any other shares of Common Stock the
beneficial ownership of which is acquired by such Principal Stockholders being
such Principal Stockholder's
 
                                       14
<PAGE>
"Subject Shares"). If the Offer is amended in any manner set forth in the Merger
Agreement as requiring the consent of the Company, the Principal Stockholders
will not be obligated to tender their Subject Shares unless such amendment is
made with their prior approval (which is not to be unreasonably withheld).
 
    VOTING OF SHARES.  At any meeting of the stockholders of the Company called
to consider and vote upon the adoption of the Merger Agreement (and at any and
all postponements and adjournments thereof), and in connection with any action
to be taken in respect of the adoption of the Merger Agreement by written
consent of stockholders of the Company, each Principal Stockholder has agreed to
vote or cause to be voted (including by written consent, if applicable) all of
such Principal Stockholder's Subject Shares in favor of the adoption of the
Merger Agreement and in favor of any other matter necessary for the consummation
of the transactions contemplated by the Merger Agreement and considered and
voted upon at any such meeting or made the subject of any such written consent,
as applicable.
 
    At any meeting of the stockholders of the Company called to consider and
vote upon any Adverse Proposal (as defined below) (and at any and all
postponements and adjournments thereof), and in connection with any action to be
taken in respect of any Adverse Proposal by written consent of stockholders of
the Company, each Principal Stockholder has agreed to vote or cause to be voted
(including by written consent, if applicable) all of such Principal
Stockholder's Subject Shares against such Adverse Proposal. For purposes of the
Stockholder Agreement, the term "Adverse Proposal" means any (a) Acquisition
Proposal, (b) proposal or action that would reasonably be expected to result in
a breach of any covenant, representation or warranty of the Company set forth in
the Merger Agreement, or (c) proposal or action that is intended or would
reasonably be expected to impede, interfere with, delay or materially and
adversely affect the Merger or any of the other transactions contemplated by the
Merger Agreement or the Stockholder Agreement.
 
    IRREVOCABLE PROXY.  Pursuant to the Stockholder Agreement, each Principal
Stockholder has appointed Parent and any designee of Parent, each of them
individually, such Principal Stockholder's proxy and attorney-in-fact pursuant
to the provisions of Section 212 of the DGCL, with full power of substitution
and resubstitution, to vote or act by written consent with respect to such
Principal Stockholder's Subject Shares in accordance with the Stockholder
Agreement. Each Principal Stockholder has affirmed that the proxy is coupled
with an interest and will be irrevocable. Each Principal Stockholder will take
such further action or execute such other instruments as may be necessary to
effectuate the intent of the proxy.
 
    GRANT OF OPTION.  Each Principal Stockholder has granted to Parent an
irrevocable option (each, an "Option" and, collectively, the "Options") to
purchase such Principal Stockholder's Subject Shares on the terms and subject to
the conditions set forth in the Stockholder Agreement at a purchase price per
share equal to $15.00 or the highest per share price paid in the Offer (the
"Purchase Price"). If (i) the Offer is consummated but (whether due to improper
tender or withdrawal of tender) the Offeror has not accepted for payment and
paid for all of the Subject Shares, or (ii) the Merger Agreement is terminated
(otherwise than by mutual consent of the parties or as a result of the entry of
a final, nonappealable injunction against the Offer or the Merger under
circumstances not involving a breach by the Company of its obligation to seek
the removal thereof) in accordance with its terms for reasons other than the
failure of Parent or the Offeror to fulfill their respective obligations under
the Merger Agreement, the Options will, in any such case, become exercisable (in
whole but not in part) upon the first to occur of any such event and remain
exercisable (in whole but not in part) until the date that is 30 days after the
date of the occurrence of an event in clause (i) above, or the date that is 90
days after the date of the occurrence of the event in clause (ii) above (the
applicable period of exercisability being the "Option Period").
 
                                       15
<PAGE>
    EXERCISE OF OPTION.  Parent may exercise all of the Options, in whole but
not in part, at any time or from time to time during the Option Period.
Notwithstanding anything in the Stockholder Agreement to the contrary, Parent
will be entitled to purchase all Subject Shares in respect of which it will have
exercised an Option in accordance with the terms of the Stockholder Agreement
prior to the expiration of the Option Period, and the expiration of the Option
Period will not affect any rights thereunder which by their terms do not
terminate or expire prior to or as of such expiration.
 
    The Stockholder Agreement provides that if Parent wishes to exercise an
Option, it will deliver to the applicable Principal Stockholder (each a "Selling
Stockholder") a written notice (an "Exercise Notice") to that effect which
specifies a date (an "Option Closing Date") not earlier than three business days
after the date such Exercise Notice is delivered for the consummation of the
purchase and sale of such Subject Shares (an "Option Closing"). If the Option
Closing cannot be effected on the Option Closing Date specified in the Exercise
Notice by reason of any applicable judgment, decree, order, law or regulation,
or because any applicable waiting period under the HSR Act will not have expired
or been terminated, (i) the Principal Stockholders have agreed to promptly take
all such actions as may be requested by Parent, and will otherwise fully
cooperate with Parent, to cause the elimination of all such impediments to the
Option Closing and (ii) the Option Closing Date specified in the Exercise Notice
will be extended to the third business day following the elimination of all such
impediments.
 
    ADJUSTMENT UPON CHANGES IN CAPITALIZATION, ETC.  In the event of any change
in the capital stock of the Company by reason of a stock dividend, subdivision,
reclassification, recapitalization, split, combination, exchange of shares,
extraordinary distribution or similar transaction, the type and number or amount
of shares, securities or other property subject to each of the Options, and the
Purchase Price payable therefor, will be adjusted appropriately, and proper
provision will be made in the agreements governing such transaction, so that (a)
Parent will receive upon exercise of any Option the type and number or amount of
shares, securities or property that Parent would have retained and/or been
entitled to receive in respect of the applicable Selling Stockholder's Subject
Shares if the Option had been exercised immediately prior to such event relating
to the Company or the record date therefor, as applicable, and (b) the
applicable Selling Stockholder will receive upon exercise of any Option granted
by such Selling Stockholder the amount of cash that such Selling Stockholder
would have received as a result of the exercise of the Option if the Option had
been exercised immediately prior to such event relating to Parent or the record
date therefor, as applicable. The foregoing adjustment will apply in a like
manner to successive stock dividends, subdivisions, reclassifications,
recapitalizations, splits, combinations, exchanges of shares, extraordinary
distributions or similar transactions.
 
    ACQUIRED SHARES.  The Stockholder Agreement provides that, in the event that
Subject Shares are acquired by Parent pursuant to the exercise of the Options
(such acquired Subject Shares being "Acquired Shares") and Parent thereafter
sells, transfers or disposes of Acquired Shares within 18 months after the
acquisition of such Acquired Shares (any such sale, transfer or disposition of
Acquired Shares occurring within such 18-month period being a "Sale"), Parent
will promptly pay to the Selling Stockholders (pro rata, in proportion to the
number of Acquired Shares purchased from each Principal Stockholder) an amount
in cash equal to the positive difference (if any) between the aggregate proceeds
received by Parent in the Sale (net of selling commissions, if any) and the
aggregate Purchase Price paid by Parent for the Acquired Shares sold,
transferred or disposed of in such Sale. Parent has agreed to effect any Sale of
Acquired Shares only to an unaffiliated party in a bona fide arm's-length
transaction.
 
    REPRESENTATIONS AND WARRANTIES.  The Stockholder Agreement contains various
representations and warranties of the parties. Each Principal Stockholder has
made certain representations and warranties with respect to: (i) title to such
Principal Stockholders' Subject Shares; (ii) authority; and
 
                                       16
<PAGE>
(iii) noncontravention. Parent and the Offeror have also made certain
representations and warranties with respect to: (i) authority; (ii)
noncontravention; and (iii) securities law compliance.
 
    RESTRICTION ON TRANSFER OF SUBJECT SHARES, PROXIES AND NONINTERFERENCE.  The
Stockholder Agreement provides that no Principal Stockholder will, directly or
indirectly: (A) except pursuant to the terms of the Stockholder Agreement and
for the conversion of Subject Shares at the Effective Time pursuant to the terms
of the Merger Agreement, offer for sale, sell, transfer, tender, pledge,
encumber, assign or otherwise dispose of, or enter into any contract, option or
other arrangement or understanding with respect to or consent to the offer for
sale, sale, transfer, tender, pledge, encumbrance, assignment or other
disposition of, any or all of such Principal Stockholder's Subject Shares; (B)
except pursuant to the terms of the Stockholder Agreement, grant any proxies or
powers of attorney, deposit any of such Principal Stockholder's Subject Shares
into a voting trust or enter into a voting agreement with respect to any of such
Principal Stockholder's Subject Shares; or (C) take any action that would
reasonably be expected to make any representation or warranty contained in the
Stockholder Agreement untrue or incorrect or have the effect of impairing the
ability of such Principal Stockholder to perform such Principal Stockholder's
obligations under the Stockholder Agreement or preventing or delaying the
consummation of any of the transactions contemplated thereby.
 
    NO SOLICITATION.  The Principal Stockholders have agreed that they will not,
and will not authorize or permit any of their respective officers, directors,
employees, agents or representatives (including without limitation any
investment bankers, financial advisors, attorneys or accountants) to, directly
or indirectly, initiate, solicit, or encourage (including by way of furnishing
information or assistance), or take any other action to facilitate, any
Acquisition Proposal, or enter into or maintain or continue discussions or
negotiations with any person in furtherance of, or approve, agree to, endorse or
recommend, any Acquisition Proposal.
 
    TERMINATION.  The Stockholder Agreement will terminate upon the earlier of
(i) the Effective Time and (ii) the date on which the Option Period expires (or,
if later, the date on which the last Option Closing occurs). The Stockholder
Agreement provides that Parent and the Offeror will not amend the Merger
Agreement to increase the Merger Consideration without the prior written consent
of the Principal Stockholders representing a majority of the Subject Shares
subject to the Stockholder Agreement.
 
ITEM 4. THE SOLICITATION OR RECOMMENDATION.
 
    (a) RECOMMENDATION OF THE BOARD OF DIRECTORS.
 
    The Board of the Company has unanimously approved the Merger Agreement and
the transactions contemplated thereby and unanimously determined that the terms
of the Offer and the Merger are fair to and in the best interests of the Company
and its stockholders. The Board unanimously recommends that the stockholders
accept the Offer and tender their shares of Common Stock to the Offeror pursuant
to the Offer.
 
    (b) BACKGROUND OF THE OFFER
 
    From time to time over the past several years, the Company has reviewed
strategic alternatives and has engaged in discussions with several potentially
interested entities with respect to a possible business combination or other
strategic transaction between the Company and such entities.
 
    In this context, the Company retained Warburg Dillon Read LLC ("Warburg
Dillon Read") in July 1997 under a one-year engagement to assist the Company in
evaluating strategic alternatives, potentially including an acquisition by a
third party of the stock or substantially all of the assets of the Company or
any other form of sale of, or merger with, the Company. In connection with this
evaluation, Warburg Dillon Read and the Company contacted several entities,
including Parent, which
 
                                       17
<PAGE>
Warburg Dillon Read, or the Company believed might be interested in a
transaction with the Company. The entities contacted, including Parent,
displayed varying degrees of interest in pursuing discussions regarding an
acquisition of, or other business combination with, the Company. The Company
held discussions with some of the entities contacted and executed
confidentiality agreements with certain of such entities, including Parent,
pursuant to which such entities were given the opportunity to examine certain
non-public information regarding the Company and its subsidiaries. Following
preliminary discussions and meetings and a preliminary review of such non-public
information of the Company, no acceptable proposals were made from any of the
entities contacted.
 
    On October 12, 1998, Mark A. Suwyn, Chairman and Chief Executive Officer of
Parent, contacted George T. Brophy, Chairman of the Board and Chief Executive
Officer of the Company, to inform him that Parent was interested in exploring a
possible acquisition of the Company by Parent and indicated a potential purchase
price of $11.00 per share of Common Stock. Mr. Brophy informed Mr. Suwyn that
the Company might be willing to engage in these discussions, but only if a
customary confidentiality agreement was signed. On October 19, 1998, Parent and
the Company entered into an agreement providing for the confidential treatment
of any discussions relating to a possible acquisition of the Company by Parent
and of any confidential information exchanged by the Company and Parent in
connection with such discussions.
 
    On October 28, 1998, officers and representatives of Parent and the Company,
including Samuel P. Frieder, a representative of Kohlberg & Company, L.L.C.
("Kohlberg") and a Director of the Company, met at the headquarters of Parent to
review and discuss financial, business, operational and other information
regarding the Company, including the status of certain legal proceedings pending
against the Company.
 
    On November 4, 1998, a representative of Parent indicated to Mr. Frieder
that Parent might be willing to pay a purchase price in the range of $12.00 to
$13.00 per share of Common Stock for all outstanding shares and reviewed with
Mr. Frieder certain financial assumptions underlying Parent's valuation of the
Company's business. Mr. Frieder indicated that he believed that the Board and
stockholders of the Company would not favor a transaction in that price range.
Further discussions were held between November 4, 1998 and November 10, 1998
among representatives of the Company and Parent regarding Parent's valuation
assumptions and indicated purchase price for the Common Stock.
 
    On November 10, 1998, representatives of Parent indicated to representatives
of the Company that Parent might be willing to increase its indicated price
range to $14.50 per share, depending upon its review of information relating to
the Company, its level of assurance that, if announced, the transaction would be
completed and other factors. Representatives of the Company indicated to
representatives of Parent that they believed that any price less than $15.00 per
share would be unacceptable to the Company's Board and stockholders.
 
    Thereafter, through approximately January 18, 1999 and with generally
increasing frequency, representatives of Parent had various meetings and
discussions with representatives of the Company in connection with Parent's due
diligence review of the Company.
 
    At a meeting on December 1, 1998, the Board by a vote of its disinterested
members approved the engagement of Kohlberg to act as its advisor for purposes
of assisting the Company in the negotiations of the terms of any agreement for
the sale of, or other business combination involving, the Company for a period
of one year. At this meeting, the Board also approved the engagement of Warburg
Dillon Read to render a written opinion regarding the fairness of the
consideration to be paid to the stockholders of the Company in any potential
sale or other business combination involving the Company. The Company formally
retained Kohlberg and Warburg Dillon Read by executing an engagement letter with
each of Kohlberg and Warburg Dillon Read on December 3, 1998, and January 5,
1999, respectively.
 
                                       18
<PAGE>
    In mid-November 1998, one of the entities with which the Company had engaged
in discussions regarding a potential sale of the Company during the summer of
1997 contacted the Company to renew discussions for a possible business
combination with the Company. In addition, during December 1998, Kohlberg, at
the request and on behalf of the Company, contacted two of the entities with
which the Company had held discussions during the summer of 1997 and which the
Company and Kohlberg viewed, together with Parent and the entity that contacted
the Company independently, as most likely to be interested in a potential
business combination with the Company and to deliver the highest value to the
Company's shareholders. The Company held preliminary discussions with and
executed confidentiality agreements with all three potentially interested
entities in December 1998, pursuant to which the Company provided such entities
with certain material non-public information with which to evaluate the Company.
Representatives of the Company held discussions with all three entities during
the course of December 1998 and in early January 1999. By the end of December
1998, two of such entities had informed the Company that they were no longer
interested in pursuing discussions with the Company. In early January 1999, the
Company canceled discussions with the third entity because of the status of its
discussions with Parent and the Company's judgment that this entity's interest
in the Company was not strong enough to jeopardize the Company's discussions
with Parent.
 
    On December 21, 1998, Parent proposed that, for a period of less than 30
days, the Company undertake to negotiate exclusively with Parent in pursuit of
the possible acquisition of the Company by Parent at a price ranging from $14.50
to $15.00 per share, in cash. In subsequent discussions, Parent also indicated
that any definitive agreement for an acquisition of the Company by Parent would
be conditioned upon the Principal Stockholders contractually committing
themselves to support and participate in the transaction. The Company rejected
Parent's request for exclusivity and emphasized the Company's position that the
purchase price be $15.00 per share of Common Stock. Without making any
commitment as to the specific manner in which the Principal Stockholders might
agree to support any transaction that might ultimately be negotiated, the
Company indicated that it was willing to continue discussions with Parent.
 
    Parent subsequently reiterated its request for exclusivity on a number of
occasions. On each such occasion, the Company refused to grant Parent
exclusivity, but indicated its willingness to pursue discussions for an
acquisition of the Company by Parent. Parent also requested that the Principal
Stockholders agree to tender their shares of Common Stock into the Offer, vote
in favor of the Merger and grant Parent an option on their shares of Common
Stock in connection with the proposed transaction. The Principal Stockholders
indicated a willingness to agree to tender their shares and vote in favor of the
Merger, but resisted Parent's request for an option.
 
    On January 8, 1999, representatives of Parent and the Company, including
Messrs. Suwyn, Brophy and Frieder, met in Chicago to discuss the possible
acquisition of the Company by Parent. At that meeting, representatives of Parent
indicated to the representatives of the Company that, subject to satisfactory
completion of Parent's financial, business and operational review of the
Company, Parent would be willing to increase its indicated price to $15.00 per
share, in cash, and representatives of the Company orally agreed not to actively
solicit any third party for a competing transaction through January 17, 1999.
 
    During a meeting of the Board of Directors held on January 15, 1999,
representatives of Warburg Dillon Read made a financial presentation to the
Board and discussed with the Board, the financial terms of the contemplated
transaction with Parent. At this meeting, counsel to the Company made a
presentation of the terms and conditions of the Merger Agreement and the
Stockholder Agreement and discussed with the Board Parent' s request that the
Principal Stockholders enter into the Stockholder Agreement and grant Parent an
option on their shares of Common Stock and the consequent impairment of the
likelihood of a superior acquisition proposal from any third party. At the
conclusion of this meeting, in light of all the reasons detailed below under
"Reasons for the
 
                                       19
<PAGE>
Transactions; Factors Considered by the Board," the Board resolved to pursue
negotiations with Parent towards a final agreement.
 
    From January 15 to January 18, 1999, representatives of the Company and
Parent and certain of their respective advisors continued to negotiate the
Merger Agreement. During this period, Parent made it clear to the Company that
it would not proceed with the transaction without an option on the Principal
Stockholders' shares of Common Stock.
 
    On January 18, 1999, the Principal Stockholders agreed to grant such option
and to the final terms of the Stockholder Agreement. Later that day, the Board
of Directors of Parent approved the Offer, the Merger, the Merger Agreement, the
Stockholder Agreement and the consummation of the transactions contemplated
thereby. Later that day, at a meeting of the Board, Warburg Dillon Read advised
the Board orally that it was of the opinion (which opinion was subsequently
confirmed in writing in an opinion dated January 19, 1999) that as of the date
of its opinion, the $15.00 per share of Common Stock cash consideration to be
received by the holders of Common Stock pursuant to the Offer and the Merger was
fair, from a financial point of view, to such holders. At this meeting, counsel
to the Company presented to the Board the final terms of the Merger Agreement.
By unanimous vote of all the Directors, the Board determined that the Parent's
offer was fair to, and in the best interests of, the stockholders of the
Company. The Board authorized and approved the execution of the Merger Agreement
and recommended that the stockholders accept the Offer, approve the Merger and
tender their shares in the Offer. A letter to the stockholders communicating the
Board's recommendation is filed with the SEC as Exhibit 8 to this Schedule 14D-9
and is attached hereto and incorporated herein by reference in its entirety. The
Board also approved an amendment to its By-laws, the Termination of the Fee
Agreement, the Plan and the Severance Arrangement. The Merger Agreement and
Stockholder Agreement were then executed on January 19, 1999, and the
transaction was announced by press release. A copy of the press release is filed
with the SEC as Exhibit 9 to this Schedule 14D-9 and is incorporated herein by
reference in its entirety.
 
    (c) REASONS FOR THE TRANSACTION; FACTORS CONSIDERED BY THE BOARD
 
    In approving the Merger Agreement and the transactions contemplated thereby
and recommending that the stockholders of the Company tender their shares of
Common Stock pursuant to the Offer, the Board considered a number of factors,
including:
 
    1. The Board considered the Company's business, prospects, financial
condition, results of operations and current business strategy as well as the
nature of, and recent trends and developments in the industry in which the
Company operates, including recent increased competition for its main product
lines. In addition, the Board considered the exposure of the Company to certain
legal proceedings pending against the Company, the status of settlement
discussions in respect thereof and the implications of a potential settlement of
such legal proceedings on the value of the Company. The Board also reviewed
possible alternatives to the Offer and the Merger, including, without
limitation, continuing to operate the Company as an independent entity, and the
risks associated therewith, including the ongoing need for financing of the
Company to make significant acquisitions, which the Board believed would be
necessary because of the continuing consolidation in the industry.
 
    2. The Board considered Parent's business reputation, the potential
synergies between Parent and the Company's businesses and Parent's ability to
finance the transaction. It is the Board's belief that it obtained the highest
immediate value for its stockholders by entering into a transaction with Parent,
which, because of the synergies that could be created by a combination of the
Company with Parent, could offer the best price for the Company's Common Stock.
 
    3. The Board considered the oral opinion of Warburg Dillon Read rendered to
the Board at its January 18, 1999 meeting (which opinion was subsequently
confirmed by delivery of a written opinion dated January 19, 1999) to the effect
that, as of the date of such opinion and based upon and subject
 
                                       20
<PAGE>
to certain matters stated in such opinion, the $15.00 per share cash
consideration to be received by holders of shares of Common Stock in the Offer
and the Merger was fair, from a financial point of view, to such holders. The
full text of Warburg Dillon Read's written opinion dated January 19, 1999, which
sets forth the assumptions made, matters considered and limitations on the
review undertaken by Warburg Dillon Read, is filed with the SEC as Exhibit 10 to
this Schedule 14D-9 and attached hereto and is incorporated herein by reference.
Warburg Dillon Read's opinion is directed only to the fairness, from a financial
point of view, of the cash consideration to be received in the Offer and the
Merger by holders of shares of Common Stock (other than Parent and its
affiliates) and is not intended to constitute, and does not constitute, a
recommendation as to whether any stockholder should tender shares of Common
Stock pursuant to the Offer. Warburg Dillon Read's opinion does not address the
Company's underlying decision to approve the Merger Agreement and the
transactions contemplated thereby. In addition, Warburg Dillon Read has not been
asked to, and did not, offer any opinion as to the material terms of the Merger
Agreement or the form of the transaction contemplated thereby. Warburg Dillon
Read has not been requested to, and did not, solicit other third party
indications of interest in acquiring the Company. In rendering its opinion,
Warburg Dillon Read has assumed with the Company's consent, that the Company and
Parent will comply with all the material terms of the Merger Agreement. HOLDERS
OF COMMON STOCK ARE URGED TO READ SUCH OPINION CAREFULLY IN ITS ENTIRETY.
 
    4. The Board considered the terms and conditions of the Merger Agreement, in
particular the fact that after lengthy discussions and negotiations between
representatives of the Company and representatives of Parent, Parent was
unwilling to enter into the Merger Agreement unless Parent was able to
simultaneously therewith enter into the Stockholder Agreement. The Board was
aware of the fact that the provisions of the Stockholder Agreement impair the
likelihood of a superior acquisition proposal from any third party. The Board
considered at length whether Parent might agree to proceed with the proposed
transaction without such provisions and concluded that Parent would not. The
Board also concluded that, in light of its knowledge of the industry and the
efforts previously made by the Company to solicit the interest of potential
buyers for the Company, it was unlikely that a superior acquisition proposal
would be made by a third party.
 
    5. The Board considered the historical market prices of, and recent trading
activity in, the shares of Common Stock, and the fact that the Offer and the
Merger will enable the stockholders of the Company to realize a premium over the
prices at which the Common Stock traded prior to the execution of the Merger
Agreement.
 
    6. The Board considered the fact that, while the provisions of the
Stockholder Agreement substantially impair the likelihood that a superior
acquisition proposal would be made by a third party, the terms of the Merger
Agreement do not preclude other parties from making bona fide superior proposals
subsequent to signing the Merger Agreement and, if any such proposal were made,
the Company, in the exercise of its fiduciary duties, could determine to provide
information to, engage in negotiations with, and, subject to payment of a
break-up fee to Parent, terminate the Merger Agreement and enter into a
transaction with, another party.
 
    7. The Board considered the likelihood that the Merger would be consummated,
including the fact that the Offer was not conditioned on financing and the
Board's reasonable satisfaction that the other conditions to the closing of the
transactions under the Merger Agreement could reasonably be expected to be met.
 
    The Board did not assign relative weights to these factors or determine that
any factor was of particular importance. Rather, the Board viewed its position
and recommendation as being based on the totality of the information presented
to and considered by it.
 
                                       21
<PAGE>
ITEM 5. PERSONS RETAINED, EMPLOYED OR TO BE COMPENSATED.
 
    The Company has retained Kohlberg to act as its financial advisor in
connection with the Offer and the Merger. Pursuant to the terms of Kohlberg's
engagement, the Company has agreed to pay Kohlberg for its services a fee
payable in cash equal to 2/3 of 1% of the total consideration (including net
debt assumed) to be received by the Company and/or its stockholders in
connection with the Offer and the Merger. The fee payable to Kohlberg is
currently estimated to be approximately $1.5 million. The Company also has
agreed to reimburse Kohlberg for reasonable expenses, including reasonable fees
and disbursements of Kohlberg's counsel, and to indemnify Kohlberg and certain
related parties against certain liabilities arising out of Kohlberg's
engagement. Kohlberg is an affiliate of the Company and an affiliate of Kohlberg
has performed and continues to perform services for the Company for which it
receives a fee under a fee agreement which will be terminated upon consummation
of the Offer. The fees and expenses paid by the Company to the Kohlberg
affiliate under this fee agreement aggregated $118,000 in 1997 and $125,000 in
1998.
 
    In addition, the Company retained Warburg Dillon Read on January 5, 1999,
for a one year period to consult with the Board regarding the financial aspects
of the proposed transaction and provide the Board with its opinion relating to
the fairness, from a financial point of view, of the consideration to be
received by the stockholders of the Company pursuant to the Offer and the
Merger. Pursuant to the terms of Warburg Dillon Read's engagement, the Company
agreed to pay Warburg Dillon Read for its services a fee equal to $100,000,
payable in cash upon execution of the engagement letter with Warburg Dillon
Read, and an additional fee of $700,000 payable in cash on the date upon which
Warburg Dillon Read issued its opinion with respect to the fairness of the
consideration in the proposed transaction. In addition, if at any time during
the term of the engagement the Company contemplates another business combination
involving, or sale of, the Company, the Company has agreed to pay Warburg Dillon
Read an additional $100,000, payable upon the date on which Warburg Dillon Read
issues any additional opinion or informs the Board that it is unable to render
such additional opinion in connection with the proposed new business combination
involving, or sale of, the Company. The Company has also agreed to reimburse
Warburg Dillon Read for its reasonable expenses in performing its services under
its engagement with the Company, and to indemnify Warburg Dillon Read and
certain related parties against certain liabilities arising out of its
engagement. Warburg Dillon Read has performed investment banking services for
the Company, affiliates of Kohlberg and Parent for which it has received
customary fees. In addition, in the ordinary course of its business, Warburg
Dillon Read may trade the securities of the Company and Parent for its own
account and for the accounts of customers and 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 stockholders in connection with the Offer.
 
ITEM 6. RECENT TRANSACTIONS AND INTENT WITH RESPECT TO SECURITIES.
 
    (a) There have been no transactions in the shares of Common Stock during the
past 60 days by the Company or, to the best of the Company's knowledge, by any
executive officer, director, affiliate or subsidiary of the Company.
 
    (b) To the best of the Company's knowledge, each of its executive officers,
directors, affiliates or subsidiaries currently intends to tender, pursuant to
the Offer, any shares of Common Stock beneficially owned individually by such
persons. The Principal Stockholders have agreed under the Stockholder Agreement
to, among other things, validly tender (and not withdraw) all of their shares of
Common Stock (representing approximately 46.4% of the outstanding shares of
Common Stock) pursuant to the offer made by Parent and the Offeror.

                INFORMATION STATEMENT PURSUANT TO SECTION 14(F)
                     OF THE SECURITIES EXCHANGE ACT OF 1934
                           AND RULE 14F-1 THEREUNDER
 
GENERAL
 
    This Information Statement is being mailed on or about January 25, 1999 as
part of the Solicitation/Recommendation Statement on Schedule 14D-9 (the
"Schedule 14D-9") of ABT Building Products Corporation (the "Company") with
respect to the tender offer by Striper Acquisition, Inc. (the "Offeror") to the
holders of record of the common stock of the Company, par value $.01 per share
(the "Common Stock"). Capitalized terms used and not otherwise defined herein
shall have the meaning set forth in the Schedule 14D-9.
 
    On January 19, 1999, the Company, Louisiana-Pacific Corporation, a Delaware
corporation ("Parent"), and the Offeror entered into an Agreement and Plan of
Merger (the "Merger Agreement") pursuant to which (i) the Offeror will commence
a tender offer (the "Offer") for all outstanding shares of Common Stock at a
purchase price per share of $15.00, net to the seller in cash, without interest
and (ii) following the consummation of the Offer, the Offeror will be merged
with and into the Company (the "Merger"). As a result of the Offer and the
Merger, the Company will become a wholly owned subsidiary of Parent.
 
    BOARD REPRESENTATION.  The Merger Agreement provides that promptly upon the
purchase by the Offeror pursuant to the Offer of such number of shares of Common
Stock (together with any shares of Common Stock then owned by Parent or any of
its subsidiaries) which represents a majority of the outstanding shares of
Common Stock (on a fully diluted basis) on the date of purchase, and from time
to time thereafter, (i) Parent shall be entitled to designate such number of
directors, rounded up to the next whole number as will give Parent
representation on the Board of Directors of the Company (the "Board of
Directors") equal to the product of (x) the number of directors on the Board of
Directors (giving effect to any increase in the number of directors pursuant to
the Merger Agreement) and (y) the percentage that such number of shares of
Common Stock so purchased in the Offer (together with any shares of Common Stock
then owned by Parent or any of its subsidiaries), bears to the aggregate number
of shares of Common Stock outstanding on the date of purchase (such number being
the "Board Percentage"), and (ii) the Company will, upon request by Parent,
promptly cause Parent's designees constituting the Board Percentage to be
elected to the Board of Directors by (x) increasing the size of the Board of
Directors or (y) using reasonable efforts to secure the resignations of such
number of directors as is necessary to enable Parent's designees to be elected
to the Board of Directors and shall use its best efforts to cause Parent's
designees promptly to be so elected, subject in all instance to compliance with
Section 14(f) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act") and Rule 14f-1 promulgated thereunder. Following the election or
appointment of Parent's designees pursuant to the Merger Agreement and prior to
the Effective Time, any amendment or termination of the Merger Agreement, waiver
of the obligations or other acts of Parent or the Offeror or waiver of the
Company's rights thereunder shall require the concurrence of a majority of the
directors of the Company then in office who are directors on the date of the
Merger Agreement and who voted to approve the Merger Agreement and such
additional directors of the Company who are not affiliated with Parent, the
Offeror or any of their affiliates and were designated as continuing directors
for purposes of the Merger Agreement by a majority of the directors that are
continuing directors for purposes of the Merger Agreement, in office at the time
of such designation. This Information Statement is provided to you pursuant to
Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder.

contemporaneously herewith. Certain other documents (including the Merger
Agreement) were filed with the Securities and Exchange Commission (the "SEC") as

14D-9. The exhibits to the Schedule 14D-1 and the Schedule 14D-9 may be examined

BOARD MEETINGS, COMMITTEES AND COMPENSATION
 
    The Board of Directors held four meetings during the year ended December 31,
1998. Each of the Company's current directors participated in all of the
meetings of the Board of Directors and of each committee of the Board of
Directors on which such person served during such year.
 
    The Board of Directors has established an Executive Committee, an Audit
Committee, a Compensation Committee and an Environmental Committee. The
Executive Committee, which consists of Messrs. Brophy, Frieder and Kohlberg,
generally exercises the powers of the Board of Directors when the Board of
Directors is not in session, subject to the limitations of Delaware law, and has
the ability to approve expenditures of up to $1.0 million. The Audit Committee,
which currently consists of Messrs. Rohrbach, Garrett, Frieder and Frazier,
oversees actions taken by the Company's independent auditors and recommends the
engagement of auditors. The Compensation Committee, which currently consists of
Messrs. Peck, Rohrbach and Frieder, approves the compensation levels and
administers the Company's incentive plans. The Environmental Committee, which
currently consists of Messrs. Frazier, Garrett and Rohrbach, oversees actions
taken by the Company to ensure compliance with Federal, state and local
environmental regulations. During 1998, the Executive Committee held four
meetings, the Audit Committee held two meetings, the Compensation Committee held
two meetings and the Environmental Committee held two meetings.
 
    Warner C. Frazier, John R. Garrett and Nelson J. Rohrbach receive a retainer
of $12,000 per annum plus $1,000 for each day on which a Board of Directors
and/or Committee meeting is attended. All directors are reimbursed for expenses
incurred in connection with attendance at meetings. Independent directors of the
Company may be granted options to purchase up to 100,000 shares in the aggregate
of Common Stock of the Company under the Company's 1994 Director Stock Option
Plan (the "Directors' Option Plan"). The Directors' Option Plan is administered
by the non-independent directors of the Compensation Committee. Options under
the Directors' Option Plan are granted at fair market value at the time of grant
and become exercisable within six months of the grant. On October 6, 1998,
options to purchase 5,000 shares were granted to each of Messrs. Rohrbach,
Garrett and Frazier, with an exercise price of $8.50 per share.

EMPLOYMENT AGREEMENTS
 
    The Company has entered into an employment agreement (as amended) with Mr.
Brophy providing for his employment as the Company's Chairman of the Board of
Directors, President and Chief Executive Officer until the earlier of (i) the
termination by the Company's Board of Directors, (ii) Mr. Brophy's death or
disability, (iii) January 1, 2000, or (iv) 180 days after notice from Mr. Brophy
of his resignation. Mr. Brophy's agreement provides for an annual salary of not
less than $250,000 (currently $420,000) plus an annual payment of $100,000 to be
made on January 1 of each year through January 1, 2000. During his employment,
Mr. Brophy is entitled to participate in the Company's medical and dental
insurance plans and all other benefit plans generally available to the Company's
executive officers as in effect from time to time. In the event that Mr.
Brophy's employment is terminated by the Board of Directors without cause (as
defined) or by reason of death or disability, Mr. Brophy is entitled to receive
a lump sum payment equal to the greater of $250,000 or the amount payable under
the Company's executive severance plan described below payable within 90 days of
such termination plus, in each case, $100,000 in cash, payable on each January 1
following such termination through January 1, 2000. The agreement also provides
a two-year non-competition agreement following Mr. Brophy's termination of
employment for any reason.
 
    The Company also entered into a consulting agreement with Mr. Brophy. This
agreement will become effective upon Mr. Brophy's retirement at age 65 from his
position with the Company and will continue for a term of five years thereafter.
Under this agreement, Mr. Brophy will provide up to 32 hours per month of
consulting services to the Board of Directors and senior management of the
Company and will not own, manage, control, participate in, consult with, render
services for or in any manner engage in hardboard siding, hardboard paneling,
fiber cement siding or vinyl siding. In
 
                                       7
<PAGE>
compensation for his services and his covenant not to compete, Mr. Brophy (or
his estate) will be entitled to receive an annual fee of $150,000 until the
termination of his agreement notwithstanding his death or disability. In the
event of Mr. Brophy's death at or prior to age 65, his spouse will be entitled
to medical coverage until she reaches age 65.
 
    The Company entered into a severance arrangement with Mr. Brophy on January
18, 1999, pursuant to which Mr. Brophy will be entitled to certain benefits,
including receiving a lump sum severance payment of $1,777,368 in full
satisfaction of all rights to severance or other post termination payments (but
excluding his rights with respect to any stock or stock options that he holds)
to which he would be entitled upon a termination of his employment with the
Company without cause or due to a voluntary termination within the period
beginning 60 days and ending 90 days after a change of control. In addition, Mr.
Brophy's unvested stock options will immediately vest and become exercisable
upon a change of control. This severance arrangement replaced and superseded any
prior severance arrangement or program sponsored by the Company for the benefit
of Mr. Brophy.
 
BONUS PLAN
 
    Each of the named executive officers and other key personnel participate in
an executive/ management bonus plan (the "Bonus Plan") providing for annual
bonus awards contingent upon achievement of certain performance targets based on
earnings before interest and taxes on both a Company-wide basis and on a
separate basis for the Company's various operations. Participants are divided
into five tiers of participation designed to reflect each participant's sphere
of responsibility within the Company. An individual participant's bonus is
determined as a percentage of base salary (not to exceed 100% effective as of
1994) based upon (i) the relevant performance target(s) achieved, (ii) the
employee's participation tier and (iii) the weighting given to the relevant
performance targets. Bonus amounts are prorated for new participants who are
added during the course of a given year. Bonus payments are subject to
modification at the discretion of the Company's Board of Directors.
 
SEVERANCE PLAN
 
    The Company adopted an executive severance policy in 1996 for the benefit of
the Company's executive officers, providing for certain payments to be made to
such officers upon their termination. On January 18, 1999, the Company adopted
an Executive Severance Pay Plan (the "Plan"), which replaced and superseded any
prior severance arrangement or program sponsored by the Company for the benefit
of the executive officers named in such Plan. The Plan covers certain executive
officers of the Company (including Messrs. Parker, Adams, Grimm and O'Neill)
having one or more full years of service and who are involuntarily terminated
due to (i) a job elimination, (ii) a reduction in force, (iii) any reason other
than for cause within one year following a change of control (as defined below)
or (iv) voluntary termination of their employment with the Company within the
period beginning 60 days and ending 90 days after the occurrence of a change of
control. A "Change of Control" under the Plan occurs when (i) any person or
group (as such term is used in Rule 13d-5 under the Exchange Act), other than
affiliates of Kohlberg & Co., is or becomes a beneficial owner, directly or
indirectly, of securities of the Company representing 50% or more of the
combined voting power of the Company then-outstanding securities, and (ii)
during any period of 24 consecutive months, commencing before or after the event
described in clause (i) above, individuals who at the beginning of such 24-month
period were directors of the Company, or persons whose election to the Board was
approved by such individuals, cease for any reason to constitute at least a
majority of the Board. Pursuant to the Plan, upon any such termination, such
officers' options will not be forfeited and will immediately vest upon such
terminations. Such officers also will be entitled to receive their monthly
salary for 18 months commencing on the date of their termination, a pro-rata
bonus payment (through the date of their termination) of their bonus entitlement
for the year of termination payable in the following January, another bonus
payment equaling the average of the prior 3 years' bonuses payable at the end of
the 18 months following their termination, and various other benefits.

STOCK OPTION PLANS
 
    The Company maintains various stock option plans (including the 1994
Employee Stock Option Plan and the Directors' Option Plan) providing for the
issuance of options to purchase up to an aggregate of 3,100,000 shares of Common
Stock (collectively, the "Stock Option Plans"). As of January 14, 1999, options
to purchase 2,522,434 shares of Common Stock were outstanding under the Stock
Option Plans at exercise prices ranging from $2.50 to $29.50 per share. The
Stock Option Plans are administered by the Compensation Committee of the Board
of Directors. The Compensation Committee determines the terms of the options
granted under the Stock Option Plans (which in certain cases, may be incentive
or nonqualified options), including the exercise price, term (not to exceed ten
years), number of shares and exercisability. The exercise price of options
issued under the Stock Option Plans must equal or exceed the fair market value
of the Common Stock on the date of grant. Payment of the option exercise price
may be made in cash or by a note (at the discretion of the Committee), by a
surrender of shares of Common Stock or a combination of the foregoing. One of
the Stock Option Plans authorizes grants of alternative cash settlement rights
that would entitle participants to receive on exercise of an option a payment in
cash equal to the excess of the then-current fair market value of the shares
with respect to which the option is exercised over the applicable exercise
price. Upon a change in control (as defined in Severance Plan), all options in
the Stock Option Plans will become fully vested.
 
    The following tables disclose information regarding stock options granted,
exercised during, or held at the end of 1998 for the named executive officers
pursuant to the Stock Option Plans. The Company has not granted any stock
appreciation rights.

RETIREMENT BENEFITS
 
    All salaried employees, including executive officers and certain hourly
employees of the Company, participate in a defined benefit pension plan funded
on an actuarial basis entirely by the Company. Although benefits for certain
hourly groups are based on a flat dollar rate multiplied by years of service,
most employees earn an annual pension benefit at age 65 equal to one percent of
their highest five-year average compensation plus three-tenths of one percent of
the amount of such compensation which exceeds "covered compensation" (as defined
in the Internal Revenue Code), all multiplied by years of service not to exceed
35 years. This plan provides for a minimum benefit of one percent of the
employee's average compensation multiplied by the employee's total years of
service. Alternative minimum benefits may be payable to some employees based on
their accruals under prior benefit formulas or predecessor plans.
 
    Certain employees whose benefits under the plan have been reduced as the
result of recent formula changes, or who are otherwise designated by the
Compensation Committee, may accrue additional benefits under supplemental
nonqualified plans which the Company has established.
 
    The following table shows the projected annual pension benefits payable
under the pension plan at the normal retirement age of 65:

                             CERTAIN RELATIONSHIPS
 
    Pursuant to a Fee Agreement (the "Fee Agreement"), dated as of October 20,
1992, between an affiliate of Kohlberg & Co. and the Company, Kohlberg & Co.
receives an annual management fee of $95,000 from the Company and will continue
to receive such fee through the earlier of (i) October 20, 2002 or (ii) the end
of the fiscal year in which the aggregate percentage ownership of the Common
Stock by affiliates of Kohlberg & Co. falls below 20%. Currently, affiliates of
Kohlberg & Co. own approximately 46.0% of the outstanding Common Stock of the
Company. On January 19, 1999 the Company entered into a Termination of Fee
Agreement with Kohlberg & Co. for the termination of the Fee Agreement,
effective upon the consummation of the Offer and payment to Kohlberg & Co. of
all fees to which it would otherwise be entitled for 1999, prorated on the basis
of the number of days elapsed and remaining, respectively, in such year at the
time of termination.
 
    The Company also retained Kohlberg & Co. to act as its financial advisor in
connection with the Offer and the Merger. Pursuant to the terms of Kohlberg &
Co.'s engagement, the Company has agreed to pay Kohlberg & Co. for its services
a fee payable in cash equal to 2/3 of 1% of the total consideration (including
net debt assumed) to be received by the Company and/or its stockholders in
connection with the Offer and the Merger. The fee payable to Kohlberg & Co. is
currently estimated to be approximately $1.5 million. The Company also has
agreed to reimburse Kohlberg & Co. for reasonable expenses, including reasonable
fees and disbursements of Kohlberg & Co.'s counsel, and to indemnify Kohlberg &
Co. and certain related parties against certain liabilities arising out of
Kohlberg & Co.'s engagement.
 
    Warner C. Frazier, a director since October 1993, is Chairman and Chief
Executive Officer of Simplicity Manufacturing, Inc., a majority interest in
which is held by an affiliate of Kohlberg & Co.
 
                                       12
<PAGE>
George Brophy is also a director of Simplicity. In addition, Mr. Brophy is a
director of Color Spot, a majority interest in which is held by an affiliate of
Kohlberg & Co.
 
    John R. Garrett, a director since May 1998, is a shareholder of Brownstein,
Hyatt, Farber & Strickland, P.C., one of the Company's outside legal counsel.
From time to time, Mr. Garrett also provides legal advice to affiliates of
Kohlberg & Co.
 
    The Company, KABT Acquisition Company, L.P., KABT II Acquisition Company,
L.P. (together with KABT Acquisition Company, L.P., "KABT"), George Brophy,
Richard Parker, William Adams, Donald Grimm and Joseph O'Neill are parties to a
Stockholders' Agreement, dated as of October 20, 1992 (the "Stockholders'
Agreement") which provides, among other things, that upon the termination of
employment of any manager who is a party to this agreement, the Company may
elect to repurchase (i) the shares of Common Stock held by such manager at fair
market value and the vested options held by such manager at the excess of fair
market value on the date of termination over the exercise price of such options,
if the termination is without "cause"; or (ii) the shares of Common Stock held
by such manager at the lesser of fair market value on the date of termination or
original cost, if the termination is with "cause." Options held by the manager
that are not vested in the case of (i) and all options in the case of (ii) will
be canceled. "Cause" for purposes of the Stockholders' Agreement means a
manager's willful and repeated failure to comply with the lawful directives of
the Board of Directors or such manager's supervisory personnel or any criminal
act or act of dishonesty, disloyalty, misconduct or moral turpitude by a manager
that is injurious to the property, operations, business or reputation of the
Company or its subsidiaries. The Stockholders' Agreement also provides KABT with
rights of first refusal upon any transfer of Common Stock by the managers party
the agreement other than transfers to such managers' family group and other than
transfers by will or pursuant to applicable laws of descent and distribution.
Holders of a majority of the Common Stock held by managers who are party to the
agreement also have participation rights in the event of a transfer of Common
Stock by KABT. The Stockholders' Agreement provides that if holders of a
majority of the Common Stock approve the sale or other transfer of the Company
to an independent third party, the managers who are party to the agreement will
consent and raise no objections (including exercising any rights or appraisal)
to the sale or transfer of the Company and will take all necessary and desirable
actions in connection with the consummation of such transaction (including
selling their stock if the transfer is structured as a stock transaction),
provided that all holders of Common Stock receive the same consideration per
share in connection with the transaction. The Stockholders' Agreement also
provides demand and piggy-back registration rights to the manager and KABT.
 
COMPLIANCE WITH SECTION 16(A) OF THE EXCHANGE ACT
 
    Section 16(a) of the Exchange Act requires the Company's officers and
directors, and persons who own more than ten percent of a registered class of
the Company's equity securities, to file reports of ownership and changes in
ownership on Forms 3, 4 and 5 with the SEC and the New York Stock Exchange.
Officers, directors and greater than ten percent owners are required to furnish
the Company with copies of all Forms 3, 4 and 5 they file.
 
    Based solely on the Company's review of the copies of such forms it has
received and written representations from certain reporting persons that they
were not required to file Forms 5 for a specified fiscal year, except as
otherwise set forth herein, the Company believes that all its officers,
directors and greater than ten percent beneficial owners complied with all
filing requirements applicable to them with respect to transactions during 1998.

                          AGREEMENT AND PLAN OF MERGER

         This AGREEMENT AND PLAN OF MERGER, dated as of January 19, 1999 (this
"Agreement"), is made and entered into among Louisiana-Pacific Corporation, a
Delaware corporation ("Parent"), Striper Acquisition, Inc., a Delaware
corporation and wholly owned subsidiary of Parent ("Merger Sub"), and ABT
Building Products Corporation, a Delaware corporation ("Company").

                                    RECITALS:

         A. The respective Boards of Directors of Parent, Merger Sub and Company
have determined that it would be advisable and in the best interests of their
respective stockholders for Parent to acquire Company, by means of a merger of
Merger Sub with and into Company (the "Merger"), on the terms and subject to the
conditions set forth in this Agreement.

         B. To effectuate the acquisition, Parent and Company each desire that
Parent cause Merger Sub to commence a cash tender offer to purchase all of the
outstanding shares of common stock, par value $0.01 per share (the "Company
Common Stock"), of Company (the "Shares") on the terms and subject to the
conditions set forth in this Agreement and the Board of Directors of Company has
approved such tender offer and is recommending (subject to the limitations
contained herein) that Company's stockholders accept the tender offer and tender
their Shares pursuant thereto.

         C. Concurrently with the execution and delivery of this Agreement and
as a condition to Parent's and Merger Sub's willingness to enter into this
Agreement, Parent has entered into a Stockholder Agreement, dated as of the date
hereof (the "Stockholder Agreement"), with each of the Principal Stockholders
(as defined in Section 9.3), pursuant to which each Principal Stockholder has
(i) agreed, among other things, to tender all Shares owned by such Principal
Stockholder pursuant to the Offer (as defined in Section 1.1) and (ii) granted
to Parent an option to purchase all Shares owned by such Principal Stockholder.

         D. Parent, Merger Sub and Company desire to make certain
representations and warranties and to enter into certain covenants in connection
with the Offer and the Merger and also to prescribe various conditions to the
consummation thereof;

         NOW, THEREFORE, in consideration of the representations, warranties and
covenants contained in this Agreement, the parties hereto hereby agree as
follows:
                                    ARTICLE I

                                    THE OFFER

         Section 1.1 THE OFFER. (a) Provided that none of the events set forth
in Exhibit A hereto shall have occurred and be continuing, as promptly as
practicable (but in any event not later than five business days after the public
announcement of the execution and delivery of this Agreement), Parent shall
cause Merger Sub to commence (within the meaning of Rule 14d-2 under the
Securities Exchange Act of 1934, as amended, and the rules and regulations


<PAGE>



promulgated thereunder (the "Exchange Act")), an offer to purchase (the "Offer")
all outstanding shares of Company Common Stock at a price of $15.00 per share,
net to the seller in cash (such price or any higher price as paid pursuant to
the Offer, the "Offer Consideration"). Notwithstanding the foregoing, if between
the date of this Agreement and the Effective Time the outstanding Shares shall
have been changed into a different number of shares or a different class, by
reason of any stock dividend, subdivision, reclassification, recapitalization,
split, combination or exchange of shares, the Offer Consideration shall be
correspondingly adjusted on a per-share basis to reflect such stock dividend,
subdivision, reclassification, recapitalization, split, combination or exchange
of shares. The obligation of Parent and Merger Sub to commence the Offer, to
consummate the Offer and to accept for payment and to pay for Shares validly
tendered in the Offer and not withdrawn shall be subject only to those
conditions set forth in Exhibit A hereto. The Offer shall initially expire 20
business days after the date of its commencement.

                  (b) Without the prior written consent of Company, Merger Sub
shall not (and Parent shall cause Merger Sub not to) (i) decrease or change the
form of the Offer Consideration or decrease the number of Shares sought pursuant
to the Offer, (ii) amend any term of the Offer in any manner adverse to holders
of Shares, (iii) change the conditions to the Offer, (iv) impose additional
conditions to the Offer, (v) waive the condition that there shall be validly
tendered and not withdrawn prior to the time the Offer expires a number of
Shares (together with any Shares then owned by Parent or any of its
Subsidiaries) which constitutes a majority of the Shares outstanding on a
fully-diluted basis on the date of purchase ("on a fully-diluted basis" meaning,
as of any date, the number of Shares outstanding (excluding any Shares held as
treasury stock by Company or any of its Subsidiaries), together with the Shares
which Company may be required to issue pursuant to obligations outstanding at
that date under employee stock or similar benefit plans or otherwise (other than
unvested Options), or (vi) extend the expiration date of the Offer beyond the
initial expiration date of the Offer (except that Merger Sub may, without the
consent of Company, (A) extend the Offer, if at the then scheduled expiration
date of the Offer any of the conditions to Merger Sub's obligation to purchase
Shares is not satisfied, until such time as such condition is satisfied or
waived, and (B) extend the Offer for any period required by any rule,
regulation, interpretation or position of the United States Securities and
Exchange Commission (the "SEC") or the staff thereof); provided, however, that,
except as set forth above and subject to applicable legal requirements, Merger
Sub may amend the Offer or waive any condition to the Offer in its sole
discretion. Assuming the prior satisfaction or waiver of the conditions to the
Offer set forth in Exhibit A hereto, Merger Sub shall, and Parent shall cause
Merger Sub to, accept for payment, and pay for all Shares validly tendered and
not withdrawn pursuant to the Offer as soon as practicable after the expiration
date thereof.

                  (c) Parent shall provide or cause to be provided to Merger Sub
on a timely basis the funds necessary to purchase any Shares that Merger Sub
becomes obligated to purchase pursuant to the Offer and shall be liable on a
direct and primary basis for the performance by Merger Sub of its obligations
under this Agreement.

         Section 1.2 OFFER DOCUMENTS. (a) As soon as practicable on the date of
commencement of the Offer, Parent and Merger Sub shall file or cause to be filed
with the SEC a Tender Offer Statement on Schedule 14D-1 (together with any
supplements or amendments thereto, the "Schedule 14D-1") with respect to the
Offer which shall comply as to form in all material respects with the provisions
of applicable federal securities laws, shall contain the offer to purchase and
related letter of transmittal and other ancillary Offer documents and
instruments


                                        2

<PAGE>



pursuant to which the Offer will be made (collectively with the Schedule 14D-1,
and with any supplements or amendments thereto, the "Offer Documents") and shall
be mailed to the holders of Shares. Company will promptly supply to Parent and
Merger Sub in writing, for inclusion in the Offer Documents, all information
concerning Company required under the Exchange Act to be included in the Offer
Documents.

                  (b) Each of Parent, Merger Sub and Company shall promptly
correct any information provided by them for use in the Offer Documents if and
to the extent that such information shall be or have become false or misleading
in any material respect, and Parent and Merger Sub shall take all lawful action
necessary to cause the Offer Documents as so corrected to be filed promptly with
the SEC and to be disseminated to holders of Shares as and to the extent
required by applicable law. In conducting the Offer, Parent and Merger Sub shall
comply in all material respects with the provisions of the Exchange Act and any
other applicable law. Company and its counsel shall be given a reasonable
opportunity to review and comment on the Offer Documents and any amendments
thereto prior to the filing thereof with the SEC.

         Section 1.3 COMPANY ACTIONS. (a) Company hereby consents to the Offer
and represents and warrants that (i) its Board of Directors (at a meeting duly
called and held) has (A) determined that each of this Agreement, the Offer and
the Merger are fair to and in the best interests of Company and its
stockholders, (B) approved and declared the advisability of this Agreement and
the transactions contemplated hereby, including the Offer and the Merger, and
(C) resolved (subject to the limitations herein contained) to recommend
acceptance of the Offer and adoption of this Agreement by the holders of Shares,
and (ii) Warburg Dillon Read LLC ("WDR") has delivered to the Board of Directors
of Company its opinion that the Offer Consideration to be received by the
holders of Shares in the Offer is fair, from a financial point of view, to such
holders. Subject to the provisions of Section 6.5(b), Company hereby consents to
the inclusion in the Offer Documents of the recommendations of the Board of
Directors of Company in favor of the Offer and the adoption of this Agreement.

                  (b) Company shall file with the SEC, simultaneously with the
filing by Parent and Merger Sub of the Schedule 14D-1, a Solicitation
Recommendation Statement on Schedule 14D-9 (together with any supplements or
amendments thereto, the "Schedule 14D-9") containing, subject to the provisions
of Section 6.5(b), the recommendations of the Board of Directors of Company in
favor of the Offer and the adoption of this Agreement. Each of Parent and Merger
Sub will promptly supply to Company in writing, for inclusion in the Schedule
14D-9, all information concerning Parent's Designees (as such term is defined in
Section 1.4 hereof), as required by Section 14(f) of the Exchange Act and Rule
14f-1 thereunder, and Company shall include such information in the Schedule
14D-9. Each of Company, Parent and Merger Sub shall promptly correct any
information provided by them for use in the Schedule 14D-9 if and to the extent
that such information shall be or have become false or misleading in any
material respect and Company shall take all lawful action necessary to cause the
Schedule 14D-9 as so corrected to be filed promptly with the SEC and
disseminated to the holders of Shares as and to the extent required by
applicable law. Parent, Merger Sub and their counsel shall be given a reasonable
opportunity to review the Schedule 14D-9 and any amendments thereto prior to the
filing thereof with the SEC.

                  (c) In connection with the Offer, Company shall promptly
furnish Parent with (or cause Parent to be furnished with) mailing labels,
security position listings and all available


                                        3

<PAGE>



listings or computer files containing the names and addresses of the record
holders of Shares as of the latest practicable date and shall furnish Parent
with (or cause Parent to be furnished with) such information and assistance
(including updated lists of stockholders, mailing labels and lists of security
positions) as Parent or its agents may reasonably request in communicating the
Offer to the record and beneficial holders of Shares. Subject to the
requirements of applicable law, and except for such actions as are necessary to
disseminate the Offer Documents and any other documents necessary to consummate
the Offer and the Merger, Parent and Merger Sub and each of their affiliates,
associates, partners, employees, agents and advisors shall hold in confidence
the information contained in such labels, lists and files, shall use such
information only in connection with the Offer and the Merger and, if this
Agreement is terminated in accordance with its terms, shall deliver promptly to
Company (or destroy and certify to Company the destruction of) all copies of
such information (and any copies, compilations or extracts thereof or based
thereon) then in their possession or under their control.

         Section 1.4 DIRECTORS. (a) Promptly upon the purchase by Merger Sub
pursuant to the Offer of such number of shares of Company Common Stock (together
with any Shares then owned by Parent or any of its Subsidiaries) as represents a
majority of the outstanding shares of Company Common Stock (on a fully diluted
basis) on the date of purchase, and from time to time thereafter, (i) Parent
shall be entitled to designate such number of directors ("Parent's Designees"),
rounded up to the next whole number that will give Parent, subject to compliance
with Section 14(f) of the Exchange Act, representation on the Board of Directors
of Company equal to the product of (x) the number of directors on the Board of
Directors of Company (giving effect to any increase in the number of directors
pursuant to this Section 1.4) and (y) the percentage that such number of shares
of Company Common Stock so purchased in the Offer (together with any Shares then
owned by Parent or any of its Subsidiaries) bears to the aggregate number of
shares of Company Common Stock outstanding on the date of purchase (such number
being, the "Board Percentage"), and (ii) Company shall, upon request by Parent,
promptly cause Parent's Designees constituting the Board Percentage to be
elected to Company's Board of Directors by (x) increasing the size of the Board
of Directors of Company or (y) using reasonable efforts to secure the
resignations of such number of directors as is necessary to enable Parent's
Designees to be elected to the Board of Directors of Company and shall use best
efforts to cause Parent's Designees promptly to be so elected, subject in all
instances to compliance with Section 14(f) of the Exchange Act and Rule 14f-1
promulgated thereunder. At the request of Parent, Company shall take, at
Parent's expense, all lawful action necessary to effect any such election.
Parent will supply to Company in writing and be solely responsible for any
information with respect to itself, Parent's Designees and Parent's officers,
directors and affiliates required by the Section 14(f) of the Exchange Act and
Rule 14f-1 promulgated thereunder to be included in the Schedule 14D-9.
Notwithstanding the foregoing, at all times prior to the Effective Time (as
defined in Section 2.3) Company's Board of Directors shall include at least two
Continuing Directors (as defined in Section 1.4(b)).

                  (b) Following the election or appointment of Parent's
Designees pursuant to this Section 1.4 and prior to the Effective Time of the
Merger, any amendment or termination of this Agreement, waiver of the
obligations or other acts of Parent or Merger Sub or waiver of Company's rights
hereunder shall require the concurrence of a majority of the Continuing
Directors then in office. For purposes of this Agreement, the term "Continuing
Directors" means at any time (i) those directors of Company who are directors on
the date hereof and who voted to approve this Agreement, and (ii) such
additional directors of Company who are not affiliated


                                        4

<PAGE>



with Parent, Merger Sub or any of their affiliates and who were designated as
"Continuing Directors" for purposes of this Agreement by a majority of the
Continuing Directors in office at the time of such designation.

                                   ARTICLE II

                                   THE MERGER

         Section 2.1 THE MERGER. On the terms and subject to the conditions set
forth in this Agreement, and in accordance with the Delaware General Corporation
Law (the "DGCL"), the Merger shall be effected and Merger Sub shall be merged
with and into Company at the Effective Time. At the Effective Time, the separate
existence of Merger Sub shall cease and Company shall continue as the surviving
corporation (as such, the "Surviving Corporation").

         Section 2.2 CLOSING. Unless this Agreement shall have been terminated
and the transactions contemplated hereby shall have been abandoned pursuant to
Article VIII, and subject to the satisfaction or waiver of all of the conditions
set forth in Article VII, the closing of the Merger (the "Closing") will take
place as soon as practicable, but in no event later than 10:00 a.m. on the
second business day (the "Closing Date") following satisfaction or waiver of all
of the conditions set forth in Article VII, other than those conditions that by
their nature are to be satisfied at the Closing, but subject to the fulfillment
or waiver of those conditions, at the offices of Jones, Day, Reavis & Pogue, 599

agreed to in writing by the parties hereto.

         Section 2.3 EFFECTIVE TIME. On the Closing Date (or on such other date
as Parent and Company may agree), the parties hereto shall file with the
Secretary of State of the State of Delaware (the "Delaware State Secretary") a
certificate of merger and any other appropriate documents, executed in
accordance with the relevant provisions of the DGCL, and shall make all other
filings or recordings required under the DGCL in connection with the Merger. The
Merger shall become effective upon the filing of the certificate of merger with
the Delaware State Secretary, or at such later time as is specified in the
certificate of merger (the "Effective Time").

         Section 2.4 EFFECTS OF THE MERGER. The Merger shall have the effects
set forth in the applicable provisions of the DGCL. Without limiting the
generality of the foregoing, and subject thereto, at the Effective Time, all

liabilities and obligations of the Surviving Corporation.

         Section 2.5 CERTIFICATE OF INCORPORATION; BYLAWS. At the Effective
Time, (a) the certificate of incorporation of Merger Sub as in effect at the
Effective Time shall, from and after the Effective Time, be the certificate of
incorporation of the Surviving Corporation until thereafter changed or amended

                                        5

<PAGE>



         Section 2.6 DIRECTORS; OFFICERS. From and after the Effective Time, (a)
the directors of Merger Sub shall be the directors of the Surviving Corporation,
until the earlier of their resignation or removal or until their respective
successors are duly elected and qualified, as the case may be, and (b) the
officers of Merger Sub shall be the officers of the Surviving Corporation, until
the earlier of their resignation or removal or until their respective successors

                                   ARTICLE III

                    EFFECT OF THE MERGER ON THE CAPITAL STOCK
            OF THE CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES

         Section 3.1 EFFECT ON CAPITAL STOCK. At the Effective Time, by virtue
of the Merger and without any action on the part of any holder of Shares or any
other shares of capital stock of Company or Merger Sub:

                  (a) COMMON STOCK OF MERGER SUB. Each share of common stock,
par value $0.01 per share, of Merger Sub issued and outstanding immediately
prior to the Effective Time shall be converted into and become one validly
issued, fully paid and nonassessable share of common stock, par value $0.01 per
share, of the Surviving Corporation.

                  (b) CANCELLATION OF TREASURY SHARES AND PARENT-OWNED SHARES.
Each Share issued and outstanding immediately prior to the Effective Time that
is owned by Company or any Subsidiary (as defined in Section 9.3) of Company or
by Parent, Merger Sub or any other Subsidiary of Parent (other than shares in
trust accounts, managed accounts, custodial accounts and the like that are
beneficially owned by third parties) shall automatically be canceled and retired
and shall cease to exist, and no cash or other consideration shall be delivered
or deliverable in exchange therefor.

                  (c) CONVERSION OF SHARES. Each share of Company Common Stock
issued and outstanding immediately prior to the Effective Time (other than
Shares to be canceled and retired in accordance with Section 3.1(b) and any
Dissenting Shares (as defined in Section 3.1(d)) shall be converted into the
right to receive the Offer Consideration, payable in cash to the holder thereof,
without any interest thereon (the "Merger Consideration"), in accordance with
Section 3.3. Notwithstanding the foregoing, if between the date of this
Agreement and the Effective Time the outstanding Shares shall have been changed
into a different number of shares or a different class, by reason of any stock
dividend, subdivision, reclassification, recapitalization, split, combination or
exchange of shares, the Merger Consideration shall be correspondingly adjusted
on a per-share basis to reflect such stock dividend, subdivision,
reclassification, recapitalization, split, combination or exchange of shares.


                  (d) DISSENTING SHARES. Notwithstanding anything in this
Agreement to the contrary, Shares issued and outstanding immediately prior to
the Effective Time held by any person who has the right to demand, and who
properly demands, an appraisal of such Shares ("Dissenting Shares") in
accordance with Section 262 of the DGCL (or any successor provision) shall not
be converted into a right to receive the Merger Consideration unless such holder
fails


                                        6

<PAGE>



to perfect or otherwise loses such holder's right to such appraisal, if any. If,
after the Effective Time, such holder fails to perfect or loses any such right
to appraisal, each such Share of such holder shall be treated as a Share that
had been converted as of the Effective Time into the right to receive the Merger
Consideration in accordance with Section 3.1(c). At the Effective Time, any
holder of Dissenting Shares shall cease to have any rights with respect thereto,
except the rights provided in Section 262 of the DGCL (or any successor
provision) and as provided in the immediately preceding sentence. Company shall
give prompt notice to Parent of any demands received by Company for appraisal of
Shares, and Parent shall have the right to participate in and direct all
negotiations and proceedings with respect to such demands. Company shall not,
except with the prior written consent of Parent, make any payment with respect
to, or settle or offer to settle, any such demands.

         Section 3.2       STOCK OPTIONS.

                  (a) At the Effective Time, each holder of a then-outstanding
option to purchase Shares under Company's Amended and Restated Stock Option
Plan, 1994 Director Stock Option Plan, 1994 Employee Stock Option Plan and new
employee compensation policy (collectively, the "Stock Option Plans") (true and
correct copies of which have been delivered or made available by Company to
Parent), whether or not then exercisable (the "Options"), shall, in settlement
thereof, receive for each Share subject to such Option an amount (subject to any
applicable withholding tax) in cash equal to the difference between the Merger
Consideration and the per Share exercise price of such Option to the extent such
difference is a positive number (such amount being hereinafter referred to as,
the "Option Consideration"); provided, however, that with respect to any person
subject to Section 16(a) of the Exchange Act, any such amount shall be paid as
soon as practicable after the first date payment can be made without liability
to such person under Section 16(b) of the Exchange Act. Upon receipt of the
Option Consideration therefor, each Option shall be canceled. The surrender of
an Option to Company in exchange for the Option Consideration shall be deemed a
release of any and all rights the holder had or may have had in respect of such
Option.

                  (b) Prior to the Effective Time, Company shall use its
reasonable best efforts to obtain all necessary consents or releases from
holders of Options under the Stock Option Plans and take all such other lawful
action as may be necessary to give effect to the transactions contemplated by
this Section 3.2. Except as otherwise agreed to by the parties, (i) the Stock
Option Plans shall terminate as of the Effective Time and the provisions in any
other plan, program or arrangement providing for the issuance or grant of any
other interest in respect of the capital stock of Company or any Subsidiary
thereof shall be canceled as of the Effective Time and (ii) Company shall use
its reasonable best efforts to assure that following the Effective Time no
participant in the Stock Option Plans or other plans, programs or arrangements
shall have any right thereunder to acquire any equity securities of Company, the
Surviving Corporation or any Subsidiary thereof and to terminate all such plans.

         Section 3.3       PAYMENT FOR SHARES.

                  (a) PAYMENT FUND. Concurrently with the Effective Time, Parent
shall deposit, or shall cause to be deposited, with or for the account of a bank
or trust company designated by Parent, which shall be reasonably satisfactory to
Company (the "Paying Agent"), for the benefit of the holders of Shares, cash in
an amount sufficient to pay the aggregate Merger


                                        7

<PAGE>



Consideration payable upon the conversion of Shares pursuant to Section 3.1(c)
(the "Payment Fund").

                  (b) LETTERS OF TRANSMITTAL; SURRENDER OF CERTIFICATES. As soon
as reasonably practicable after the Effective Time, Parent shall instruct the
Paying Agent to mail to each holder of record (other than Company or any of its
Subsidiaries or Parent, Merger Sub or any other Subsidiary of Parent) of a
certificate or certificates that, immediately prior to the Effective Time,
evidenced outstanding Shares (the "Certificates"), (i) a form of letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon proper delivery of the
Certificates to the Paying Agent, and shall be in such form and have such other
provisions as Parent may reasonably specify) and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for the Merger
Consideration. Upon surrender of a Certificate for cancellation to the Paying
Agent together with such letter of transmittal, duly executed, and such other
customary documents as may be required pursuant to such instructions, the holder
of such Certificate shall be entitled to receive in exchange therefor cash in an
amount equal to the product of (i) the number of Shares theretofore represented
by such Certificate and (ii) the Merger Consideration, and the Certificate so
surrendered shall forthwith be canceled. No interest shall be paid or accrued on
any cash payable upon the surrender of any Certificate. If payment is to be made
to a person other than the person in whose name the surrendered Certificate is
registered, it shall be a condition of payment that the Certificate so
surrendered shall be properly endorsed or otherwise in proper form for transfer
and that the person requesting such payment shall pay any transfer or other
taxes required by reason of the payment to a person other than the registered
holder of the surrendered Certificate or established to the satisfaction of
Parent and the Surviving Corporation that such taxes have been paid or are not
applicable.

                  (c) CANCELLATION AND RETIREMENT OF SHARES; NO FURTHER RIGHTS.
As of the Effective Time, all Shares (other than Shares to be canceled in
accordance with Section 3.1(b)) issued and outstanding immediately prior to the
Effective Time shall cease to be outstanding and shall automatically be canceled
and retired and shall cease to exist, and each holder of any such Shares shall
cease to have any rights with respect thereto or arising therefrom (including
without limitation the right to vote), except the right to receive the Merger
Consideration, without interest, upon surrender of such Certificate in
accordance with Section 3.3(b), and until so surrendered, each such Certificate
shall represent for all purposes only the right to receive the Merger

                  (a) As soon as practicable following the acceptance for
payment of and payment for Shares by Merger Sub in the Offer, if required by law
to consummate the Merger, Company shall take all action necessary, in accordance
with the DGCL, the Exchange Act and other applicable law and its certificate of
incorporation and bylaws to convene and hold a special meeting of the
stockholders of Company (the "Stockholders Meeting") for the purpose of
considering and voting upon this Agreement and to solicit proxies pursuant to
the Proxy Statement in connection therewith. Subject to the provisions of
Section 6.5(b), the Board of Directors of Company shall recommend that the
holders of Shares vote in favor of the adoption of this Agreement at the
Stockholders Meeting and shall cause such recommendation to be included in the
Proxy Statement. At the Stockholders Meeting, Parent and Merger Sub shall cause
all of the Shares owned by them to be voted in favor of the adoption of this
Agreement.

                  (b) As soon as practicable following the acceptance for
payment of and payment for Shares by Merger Sub in the Offer, if required by
applicable law in order to consummate the Merger, Company, in consultation with
Parent, shall prepare and file with the SEC a proxy statement or information
statement (together with any supplement or amendment thereto, the "Proxy
Statement") relating to the Stockholders Meeting in accordance with the Exchange
Act and the rules and regulations thereunder. Parent, Merger Sub and Company
will cooperate with each other in the preparation of the Proxy Statement.
Without limiting the generality or effect of the foregoing, Company shall use
its reasonable efforts to respond to all SEC comments with respect to the Proxy
Statement and, subject to compliance with SEC rules and regulations, to cause
the Proxy Statement to be mailed to Company's stockholders at the earliest
practicable date. Each of Parent and Merger Sub shall promptly supply to Company
in writing, for inclusion in the Proxy Statement, all information concerning
Parent and Merger Sub required under the Exchange Act and the rules and
regulations thereunder to be included in the Proxy Statement.

                  (c) Notwithstanding the foregoing clauses (a) and (b), in the
event that Merger Sub or any other wholly-owned Subsidiary of Parent shall
acquire at least 90% of the outstanding shares of Company Common Stock in the
Offer, the parties hereto shall, at the request of Merger Sub, take all
necessary actions to cause the Merger to become effective, as soon as
practicable after the expiration of the Offer, without a meeting of stockholders
of Company, in accordance with Section 253 of the DGCL.

                  (d) Parent shall: (i) cause Merger Sub promptly to submit this
Agreement for adoption by its sole stockholder; (ii) cause the outstanding
shares of capital stock of Merger Sub to be voted in favor of the adoption of
this Agreement; and (iii) cause to be taken all additional actions necessary for
Merger Sub to adopt this Agreement.

its officers, employees, counsel, financial

<PAGE>



advisors and other representatives reasonable access (subject, however, to
existing confidentiality and similar non-disclosure obligations) during normal
business hours and upon reasonable notice during the period prior to the
Effective Time to all of Company's and its Subsidiaries' properties, books,
contracts, commitments, Returns, personnel and records and, during such period,
Company shall, and shall cause each of its Subsidiaries to, furnish as promptly
as practicable to Parent such information concerning Company's and its
Subsidiaries' businesses, properties, financial condition, operations and
personnel as Parent may from time to time reasonably request. Any such
investigation by Parent shall not affect the representations or warranties of
Company contained in this Agreement. Except as required by law, Parent and
Company will hold, and will cause its directors, officers, employees,
accountants, counsel, financial advisors and other representatives and
affiliates to hold, any non-public information obtained from the other in
confidence to the extent required by, and in accordance with the provisions of,
the letter agreement, dated October 19, 1998, between Parent and Company with
respect to confidentiality and other matters.

         Section 6.3 REASONABLE BEST EFFORTS. On the terms and subject to the
conditions set forth in this Agreement, each of the parties shall use its
reasonable best efforts to take, or cause to be taken, all actions, and do, or
cause to be done, and assist and cooperate with the other parties in doing, all
things necessary, proper or advisable to consummate and make effective, in the
most expeditious manner practicable, the Offer, the Merger and the other
transactions contemplated hereby, including the satisfaction of the respective
conditions set forth in Article VII.

         Section 6.4 PUBLIC ANNOUNCEMENTS. Parent and Merger Sub, on the one
hand, and Company, on the other hand, shall consult with each other before
issuing, and provide each other the opportunity to review and comment upon, any
press release, SEC filing (including without limitation the Offer Documents, the
Schedule 14D-9 and the Proxy Statement) or other public statements with respect
to the transactions contemplated hereby, including the Offer and Merger, and
shall not issue any such press release or make any such public statement prior
to such consultation, except as may be required by applicable law, by court
process or by obligations pursuant to any listing agreement with any national
securities exchange.

         Section 6.5       NO SOLICITATION; ACQUISITION PROPOSALS.

                  (a) During the period from and including the date of this
Agreement to and including the Effective Time, Company shall not, and shall not
authorize or permit any of its Subsidiaries, or any of its or their affiliates,
officers, directors, employees, agents or representatives (including without
limitation any investment banker, financial advisor, attorney or accountant
retained by Company or any of its Subsidiaries), to, directly or indirectly,
initiate, solicit or encourage (including by way of furnishing information or
assistance), or take any other action to facilitate, any Acquisition Proposal
(as defined in Section 6.5(d)), or enter into or maintain or continue
discussions or negotiations with any person in furtherance of, or approve, agree
to, endorse or recommend, any Acquisition Proposal; provided, however, that
nothing in this Agreement shall prohibit the Board of Directors of Company,
prior to the time at which this Agreement shall have been adopted by Company's
stockholders, from furnishing information to, or entering into, maintaining or
continuing discussions or negotiations with, any person that makes a bona fide
written Acquisition Proposal after the date hereof under circumstances not
involving any breach of the provisions of this Section 6.5(a) if, and to the
extent that, (i) the


                                       27

<PAGE>



Board of Directors of Company, after consultation with and based upon the advice
of independent legal counsel, determines in good faith that the failure to take
such action would constitute a breach by the Board of Directors of Company of
its fiduciary duties to Company's stockholders under applicable law and (ii)
prior to furnishing any non-public information to such person, Company receives
from such person an executed confidentiality agreement with provisions no less
favorable to Company than the letter agreement relating to the furnishing of
confidential information of Company to Parent referred to in the last sentence
of Section 6.2. Company shall promptly (and, in any event within 24 hours)
notify Parent after receipt of any Acquisition Proposal or any request for
information relating to Company or any of its Subsidiaries or for access to the
properties, books or records of Company or any of its Subsidiaries by any person
who has informed Company that such person is considering making, or has made, an
Acquisition Proposal (which notice shall identify the person making, or
considering making, such Acquisition Proposal and shall set forth the material
terms of any Acquisition Proposal received), and Company shall keep Parent
informed in reasonable detail of the terms, status and other pertinent details
of any such Acquisition Proposal.

                  (b) During the period from and including the date of this
Agreement to and including the Effective Time, neither the Board of Directors of
Company nor any committee thereof shall withdraw or modify, or propose publicly
to withdraw or modify, in a manner adverse to Parent or Merger Sub, the approval
of this Agreement or the transactions contemplated hereby or the recommendations
referred to in Section 1.3 or the penultimate sentence of Section 6.1(a);
provided, however, that nothing contained in this Agreement will prohibit the
Board of Directors of Company from withdrawing or modifying the recommendations
referred to in Section 1.3 or the penultimate sentence of Section 6.1(a)
following the receipt by Company after the date hereof, under circumstances not
involving any breach of the provisions of Section 6.5(a), of an Acquisition
Proposal if, and to the extent that, the Board of Directors of Company, after
consultation with and based upon the advice of independent legal counsel,
determines in good faith that the failure to take such action would constitute a
breach by the Board of Directors of Company of its fiduciary duties to Company's
stockholders under applicable law; and provided further that nothing contained
in this Agreement will prohibit the Board of Directors of Company from, to the
extent applicable, complying with Rule 14e-2 promulgated under the Exchange Act
with regard to an Acquisition Proposal.

                  (c) Subject to Company's right to terminate this Agreement
pursuant to Section 8.1(a)(vi), nothing in this Section 6.5, and no action taken
by the Board of Directors of Company pursuant to this Section 6.5, will permit
Company to enter into any agreement providing for any transaction contemplated
by an Acquisition Proposal for as long as this Agreement remains in effect.

                  (d) For purposes of this Agreement, "Acquisition Proposal"
means an inquiry, offer, proposal or other indication of interest regarding any
of the following (other than the transactions provided for in this Agreement,
the Stockholder Agreement or the Fiber Cement Agreement involving Company: (i)
any merger, consolidation, share exchange, recapitalization, business
combination or other similar transaction; (ii) any sale, lease, exchange,
mortgage, pledge, transfer or other disposition of all or substantially all the
assets of Company and its Subsidiaries, taken as a whole, in a single
transaction or series of related transactions; (iii) any tender offer or
exchange offer for or other acquisition of 20% percent or more of the
outstanding


                                       28

<PAGE>



shares of capital stock of Company or the filing of a registration statement
under the Securities Act in connection therewith; or (iv) any public
announcement of a proposal, plan or intention to do any of the foregoing or any
agreement to engage in any of the foregoing.

         Section 6.6 CONSENTS, APPROVALS AND FILINGS. Upon the terms and subject
to the conditions hereof, each of the parties hereto shall (a) make promptly its
respective filings, and thereafter make any other required submissions, under
the HSR Act and the Exchange Act, with respect to the Offer, the Merger and the
other transactions contemplated hereby and (b) use its reasonable best efforts
to take, or cause to be taken, all appropriate action, and to do, or cause to be
done, all things necessary, proper or advisable under applicable laws and
regulations to consummate and make effective the Offer, the Merger and the other
transactions contemplated hereby, including without limitation using its
reasonable best efforts to obtain all licenses, permits, consents, approvals,
authorizations, qualifications and orders of Governmental Entities and parties
to contracts with Company and its Subsidiaries as are necessary for the
consummation of the Offer, the Merger and the other transactions contemplated
hereby and to fulfill the conditions to the Offer and the Merger; provided,
however, that in no event shall Parent or any of its Subsidiaries be required to
agree or commit to divest, hold separate, offer for sale, abandon, limit its
operation of or take similar action with respect to any assets (tangible or
intangible) or any business interest of it or any of its Subsidiaries (including
without limitation the Surviving Corporation after consummation of the Offer or
the Merger) in connection with or as a condition to receiving the consent or
approval of any Governmental Entity (including without limitation under the HSR
Act). In case at any time after the Effective Time any further action is
necessary or desirable to carry out the purposes of this Agreement, the proper
officers and directors of each party to this Agreement shall use their
reasonable best efforts to take all such action.

         Section 6.7       EMPLOYEE BENEFIT MATTERS.

                  (a) From and after the Effective Time, Parent shall, and shall
cause its Subsidiaries (including the Surviving Corporation) to, honor and
provide for payment of all accrued obligations and benefits, including but not
limited to any bonus payments earned in respect of fiscal 1998 but not yet paid,
under all Company Plans and employment or severance agreements between Company
and persons who are or had been employees of Company or any of its Subsidiaries
at or prior to the Effective Time ("Covered Employees"), all in accordance with
their respective terms.

                  (b) From and after the Effective Time, Parent shall, and shall
cause its Subsidiaries (including the Surviving Corporation) to, provide Covered
Employees who remain in the employ of Parent or any such Subsidiary employee
benefits that are reasonably comparable to the employee benefits provided to
similarly situated employees of Parent or any such Subsidiary who are not
Covered Employees. To the extent that Covered Employees are included in any
benefit plan of Parent or its Subsidiaries, Parent agrees that the Covered
Employees shall receive credit under such plan for service prior to the
Effective Time with Company and its Subsidiaries to the same extent such service
was counted under similar Company Plans for purposes of eligibility, vesting,
eligibility for retirement (but not for benefit accrual) and, with respect to
vacation, disability and severance, benefit accrual. To the extent that Covered
Employees are included in any medical, dental or health plan other than the plan
or plans they participated in at the Effective Time, no such plans shall include
pre-existing


                                       29

<PAGE>



condition exclusions, except to the extent such exclusions were applicable under
the similar Company Plan at the Effective Time, and all such plans shall provide
credit for any deductibles and co-payments applied or made with respect to each
Covered Employee in the calendar year of the change.

                  (c) Notwithstanding anything in this Agreement to the
contrary, from and after the Effective Time, the Surviving Corporation will have
sole discretion over the hiring, promotion, retention, firing and other terms
and conditions of the employment of employees of the Surviving Corporation.
Except as otherwise provided in this Section 6.7, nothing herein shall prevent
Parent or the Surviving Corporation from amending or terminating any Company
Plan in accordance with its terms.

         Section 6.8       INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE.

                  (a) The provisions with respect to indemnification set forth
in the certificate of incorporation and bylaws of Merger Sub as in effect on the
date of this Agreement (true, correct and complete copies of which have been
provided to Company) shall be substantially identical to the corresponding
indemnification provisions, if any, contained in the certificate of
incorporation and by-laws of Company and, for a period of six years after the
Effective Time, shall not be amended, repealed or otherwise modified in any
manner that would adversely affect the rights thereunder of individuals who at
any time prior to the Effective Time were directors or officers of Company in
respect of actions or omissions occurring at or prior to the Effective Time
(including without limitation the transactions contemplated by this Agreement),
unless such modification is required by law.

                  (b) From and after the Effective Time, Parent shall, or shall
cause the Surviving Corporation to, indemnify, defend and hold harmless each
person who is now, or has been at any time prior to the date hereof or who
becomes prior to the Effective Time, an officer or director of Company (the
"Indemnified Parties") against all losses, claims, damages, costs, expenses
(including reasonable attorneys' fees and expenses), liabilities or judgments or
amounts that are paid in settlement with the approval of the indemnifying party
(which approval shall not be unreasonably withheld) incurred in connection with
any threatened or actual action, suit or proceeding based in whole or in part on
or arising in whole or in part out of the fact that such person is or was a
director or officer of Company ("Indemnified Liabilities"), including all
Indemnified Liabilities based in whole or in part on, or arising in whole or in
part out of, this Agreement or the transactions contemplated hereby, in each
case, to the full extent that a corporation is permitted under the DGCL to
indemnify its own directors or officers, as the case may be (and shall pay
expenses in advance of the final disposition of any such action, suit or
proceeding to each Indemnified Party to the full extent permitted by the DGCL,
upon receipt of an undertaking by or on behalf of such Indemnified Party to
repay such amount if it shall ultimately be determined that such person is not
entitled to be so indemnified). In the event any such claim, action, suit,
proceeding or investigation is brought against any Indemnified Party, the
indemnifying party shall have a right to assume and direct all aspects of the
defense thereof, including settlement, and the Indemnified Party shall cooperate
in the vigorous defense of any such matter. The Indemnified Party shall have a
right to participate in (but not control) the defense of any such matter with
its own counsel and at its own expense. The indemnifying party shall not settle
any such matter unless (i) the Indemnified Party gives prior written consent,
which shall not be unreasonably withheld, or (ii) the terms of the settlement
provide that the


                                       30

<PAGE>



Indemnified Party shall have no responsibility for the discharge of any
settlement amount and impose no other obligations or duties on the Indemnified
Party and the settlement provides the Indemnified Parties with a full release
and discharges all rights against the Indemnified Party with respect to such
matter. In no event shall the indemnifying party be liable for any settlement
effected without its prior written consent. Any Indemnified Party wishing to
claim indemnification under this Section 6.8(b), upon learning of any such
claim, action, suit, proceeding or investigation, shall notify Parent and the
Surviving Corporation (but the failure so to notify shall not relieve the
indemnifying party from any liability which it may have under this Section
6.8(b) except to the extent such failure prejudices such indemnifying party),
and shall deliver to Parent and the Surviving Corporation the undertaking
contemplated by Section 145(e) of the DGCL. The Indemnified Parties as a group
will be represented by a single law firm with respect to each such matter unless
there is, under applicable standards of professional conduct (as determined in
good faith by counsel to the Indemnified Parties), a conflict on any significant
issue between the positions of any two or more Indemnified Parties. The rights
to indemnification under this Section 6.8(b) shall continue in full force and
effect for a period of four years from the Effective Time; provided, however,
that all rights to indemnification in respect of any Indemnified Liabilities
asserted or made within such period shall continue until the disposition of such
Indemnified Liabilities.

                  (c) For a period commencing at the Effective Time and expiring
on the sixth anniversary of the Effective Time, Parent shall cause to be
maintained in effect policies of directors' and officers' liability insurance,
for the benefit of those persons who are covered by Company's directors' and
officers' liability insurance policies at the Effective Time, providing coverage
with respect to matters occurring prior to the Effective Time that is at least
equal to the coverage provided under Company's current directors' and officers'
liability insurance policies, to the extent that such liability insurance can be
maintained at an annual cost to Parent not greater than $350,000; provided that
if such insurance cannot be so maintained at such cost, Parent shall maintain as
much of such insurance as can be so maintained at a cost equal to $350,000.

                  (d) The provisions of this Section 6.8 (i) are intended to be
for the benefit of, and will be enforceable by, each Indemnified Party, his or
her heirs and his or her representatives and (ii) are in addition (without
duplication) to any other rights to indemnification or contribution that any
such person may have by contract or otherwise.

                              CONDITIONS PRECEDENT

         Section 7.1 CONDITIONS TO EACH PARTY'S OBLIGATION TO EFFECT THE MERGER.
The respective obligation of each party to effect the Merger shall be subject to
the satisfaction or written waiver on or prior to the Closing Date of the
following conditions:

                  (a) COMPLETION OF THE OFFER. Merger Sub shall have accepted
for payment and paid for all Shares validly tendered in the Offer and not
withdrawn; provided, however, that neither Parent nor Merger Sub may invoke this
condition if Merger Sub shall have failed to purchase Shares so tendered and not
withdrawn in violation of the terms of this Agreement or the Offer.

<PAGE>



                  (b) STOCKHOLDER APPROVAL. This Agreement shall have been
adopted by the affirmative vote of the holders of the requisite number of shares
of capital stock of Company if such vote is required pursuant to Company's
certificate of incorporation, the DGCL or other applicable law.

                  (c) NO INJUNCTIONS OR RESTRAINTS. No temporary restraining
order, preliminary or permanent injunction or other order issued by any court of
competent jurisdiction or other legal restraint or prohibition preventing the
consummation of the Merger shall be in effect; provided, however, that prior to
invoking this condition, the party so invoking this condition shall have
complied with its obligations under Section 6.6.

                  (d) HSR ACT. All necessary waiting periods under the HSR Act
applicable to the Merger shall have expired or been earlier terminated.

                        TERMINATION, AMENDMENT AND WAIVER

         Section 8.1       TERMINATION.

                  (a) This Agreement may be terminated and the transactions
contemplated hereby may be abandoned at any time prior to the Effective Time,
notwithstanding adoption thereof by the stockholders of Company, in any one of
the following circumstances:

                            (i) By mutual written consent duly authorized by the
Boards of Directors of Parent and Company, subject to Section 1.4(b).

                            (ii) By Parent or Company, if Shares have not been
purchased by Merger Sub pursuant to the Offer on or before April 30, 1999,
otherwise than as a result of any material breach of any provision of this
Agreement by the party seeking to effect such termination.

                            (iii) By Parent or Company if, as the result of the
failure of any of the conditions set forth in Exhibit A to this Agreement, the
Offer shall have expired or Merger Sub shall have terminated the Offer in
accordance with its terms without Merger Sub having purchased any Shares
pursuant to the Offer; provided, however, that the right to terminate this
Agreement pursuant to this Section 8.1(a)(iii) shall not be available to any
party whose breach of or failure to fulfill its obligations under this Agreement
resulted in the failure of any such condition;

                            (iv) By Parent or Company, if any court of competent
jurisdiction or other Governmental Entity shall have issued an order, decree or
ruling or taken any other action permanently enjoining, restraining or otherwise
prohibiting the Merger or the acceptance for payment of, or payment for, the
Shares pursuant to the Offer and such order, decree or ruling or other action
shall have become final and nonappealable, provided that the party seeking to
terminate this Agreement shall have used its reasonable best efforts to remove
or lift such order, decree or ruling;


                                       32

<PAGE>



                            (v) By Parent, if the Board of Directors of Company
or any committee thereof shall have (A) withdrawn or modified in a manner
adverse to Parent or Merger Sub, or publicly taken a position materially
inconsistent with, its approval or recommendation of this Agreement, the Offer,
the Merger or the other transactions contemplated hereby, (B) approved, endorsed
or recommended an Acquisition Proposal, or (C) resolved or publicly disclosed
any intention to do any of the foregoing;

                            (vi) By Company, following the receipt by Company
after the date hereof, under circumstances not involving any breach of the
provisions of Section 6.5(a), of a bona fide written Acquisition Proposal, if
the Board of Directors of Company, after consultation with and based upon the
advice of independent legal counsel, shall have determined in good faith that
the failure to terminate this Agreement would constitute a breach by the Board
of Directors of Company of its fiduciary duties to Company's stockholders under
applicable law; provided that (A) Company has complied with all provisions of
Section 6.5, including the notice provisions therein, (B) Company enters into a
definitive agreement providing for the transactions contemplated by such
Acquisition Proposal immediately following such termination, and (C) such
termination shall not be effective until Company shall have paid to Parent the
Fee (as defined below) in accordance with provisions of Section 8.1(b); or

                            (vii) by Company if Merger Sub or Parent shall have
(A) failed to commence the Offer within five business days after the public
announcement by Parent and Company of this Agreement, (B) failed to pay for the
Shares pursuant to the Offer in accordance with this Agreement, or (C) breached
in any material respect any of their respective representations, warranties,
covenants or other agreements contained in this Agreement, which breach
described in this clause (C) is incapable of being cured or has not been cured
within 20 days after the giving of written notice to Parent or Merger Sub, as
applicable, except such breaches described in this clause (C) as individually or
in the aggregate would not reasonably be expected to materially and adversely
affect the ability of Parent or Merger Sub to complete the Offer or the Merger

         Section 9.7 GOVERNING LAW. This Agreement shall be governed by, and
construed in accordance with, the laws of the State of Delaware, regardless of

interests or obligations under this Agreement may be assigned or delegated, in
whole or in part, by operation of law or otherwise by any of the parties without
the prior written consent of the other parties, and any such assignment without

Subsidiary of Parent without the prior consent of Company; provided that Parent
and/or Merger Sub, as the case may be, shall remain liable for all of its
obligations under this Agreement. Subject to the preceding sentence, this
Agreement will be binding upon, inure to the benefit of, and be enforceable by,

with their specific terms or were otherwise breached. Accordingly, the parties
shall be entitled to an injunction or injunctions to prevent breaches of this
Agreement and to enforce specifically the terms and provisions of this Agreement
in the Court of Chancery in and for New Castle County in the State of Delaware

dispute arises out of this Agreement or


                                       37

<PAGE>



any of the transactions contemplated hereby, (ii) shall not attempt to deny or
defeat such personal jurisdiction by motion or other request for leave from any
such court, and (iii) shall not bring any action relating to this Agreement or
any of the transactions contemplated hereby in any court other than the Court of
Chancery in and for New Castle County in the State of Delaware (or, if such
court lacks subject matter jurisdiction, any appropriate state or federal court
in New Castle County in the State of Delaware).

         Section 9.10 SEVERABILITY. Whenever possible, each provision or portion
of any provision of this Agreement shall be interpreted in such manner as to be
effective and valid under applicable law, but if any provision or portion of any
provision of this Agreement is held to be invalid, illegal or unenforceable in
any respect under any applicable law or rule in any jurisdiction, such
invalidity, illegality or unenforceability shall not affect any other provision
or portion of any provision in such jurisdiction, and this Agreement shall be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision or portion of any provision had never been
contained herein.

         Section 9.11 COUNTERPARTS. This Agreement may be executed in one or
more counterparts, all of which shall be considered one and the same instrument
and shall become effective when one or more counterparts have been signed by
each of the parties and delivered to the other parties.

                  (b) OTHER PROXIES REVOKED. Each Stockholder represents that
any proxies heretofore given in respect of such Stockholder's Subject Shares are
not irrevocable, and that all such proxies are hereby revoked.

                                   ARTICLE III

                                 PURCHASE OPTION

         Section 3.1 GRANT OF OPTION. Each Stockholder hereby grants to Parent
an irrevocable option (each, an "Option" and, collectively, the "Options") to
purchase such Stockholder's Subject Shares on the terms and subject to the
conditions set forth herein at a purchase price per share equal to $15.00 or the
highest per share price paid in the Offer (the "Purchase Price"). If (i) the
Offer is consummated but (whether due to improper tender or withdrawal of
tender) Merger Sub has not accepted for payment and paid for all of the Subject
Shares, or (ii) the Merger Agreement is terminated (otherwise than pursuant to
Section 8.1(a)(i) thereof or pursuant to Section 8.1(a)(iv) thereof under
circumstances in which Company is entitled to so terminate the Merger Agreement)
in accordance with its terms for reasons other than the failure of Parent or
Merger Sub to fulfill their respective obligations under the Merger Agreement,
the Options shall, in any such case, become exercisable (in whole but not in
part) upon the first to occur of any such event and remain exercisable (in whole
but not in part) until the date that is 30 days after the date of the occurrence
of an event in clause (i) above, or the date that is 90 days after the date of
the occurrence of the event in clause (ii) above (the applicable period of
exercisability being the "Option Period").

         Section 3.2 EXERCISE OF OPTION. (a) Parent may exercise all of the
Options, in whole but not in part, at any time or from time to time during the
Option Period. Notwithstanding anything in this Agreement to the contrary,
Parent shall be entitled to purchase all Subject Shares in respect of which it
shall have exercised an Option in accordance with the terms hereof prior to the
expiration of the Option Period, and the expiration of the Option Period shall
not affect any rights hereunder which by their terms do not terminate or expire
prior to or as of such expiration.

                  (b) If Parent wishes to exercise an Option, it shall deliver
to the applicable Stockholder (each a "Selling Stockholder") a written notice
(an "Exercise Notice") to that effect which specifies a date (an "Option Closing
Date") not earlier than three business days after the date such Exercise Notice
is delivered for the consummation of the purchase and sale of such Subject
Shares (an "Option Closing"). If the Option Closing cannot be effected on the
Option Closing Date specified in the Exercise Notice by reason of any applicable
judgment, decree, order, law or regulation, or because any applicable waiting
period under the HSR Act shall not have expired or been terminated, (i) the
Stockholders shall promptly take all such actions as may be requested by Parent,
and shall otherwise fully cooperate with Parent, to cause the elimination of all
such impediments to the Option Closing and (ii) the Option Closing Date
specified in the Exercise Notice shall be extended to the third business day
following the elimination of all such impediments. The place of the Option
Closing shall be at the offices of Jones, Day, Reavis & Pogue, 599 Lexington
Avenue, 32nd Floor, New York, New York 10022, and the time of the Option Closing
shall be 10:00 a.m. (Eastern Time) on the Option Closing Date.

         Section 3.3 PAYMENT AND DELIVERY OF CERTIFICATES. At any Option
Closing, Parent shall deliver to each Selling Stockholder, by wire transfer of
immediately available funds to such account as shall have been designated by
such Selling Stockholder to Parent prior to the Option Closing, the Purchase
Price payable in respect of the Subject Shares to be purchased from such Selling
Stockholder at the Option Closing, and each Selling Stockholder shall deliver to
Parent such Subject Shares, free and clear of all Liens, with the certificate or
certificates evidencing such Subject Shares being duly endorsed for transfer by
such Selling Stockholder and accompanied by all powers of attorney and/or other
instruments necessary to convey valid and unencumbered title thereto to Parent,
and shall assign to Parent (pursuant to a written instrument in form and
substance satisfactory to Parent) all rights that such Selling Stockholder may
have to require Company to register such Subject Shares under the Securities
Act.

         Section 3.4 ADJUSTMENT UPON CHANGES IN CAPITALIZATION, ETC. In the
event of any change in the capital stock of Company by reason of a stock
dividend, subdivision, reclassification, recapitalization, split, combination,
exchange of shares, extraordinary distribution or similar transaction, the type
and number or amount of shares, securities or other property subject to each of
the Options, and the Purchase Price payable therefor, shall be adjusted
appropriately, and proper provision shall be made in the agreements governing
such transaction, so that (a) Parent shall receive upon exercise of any Option
the type and number or amount of shares, securities or property that Parent
would have retained and/or been entitled to receive in respect of the applicable
Selling Stockholder's Subject Shares if the Option had been exercised
immediately prior to such event relating to Company or the record date therefor,
as applicable, and (b) the applicable Selling Stockholder shall receive upon
exercise of any Option granted by such Selling Stockholder the amount of cash
that such Selling Stockholder would have received as a result of the exercise of
the Option if the Option had been exercised immediately prior to such event
relating to Parent or the record date therefor, as applicable. The provisions of
this Section 3.4 shall apply in a like manner to successive stock dividends,
subdivisions, reclassifications, recapitalizations, splits, combinations,
exchanges of shares, extraordinary distributions or similar transactions.

         Section 3.5 ACQUIRED SHARES. In the event that Subject Shares are
acquired by Parent pursuant to the exercise of the Options (such acquired
Subject Shares being "Acquired Shares") and Parent thereafter sells, transfers
or disposes of Acquired Shares within 18 months after the acquisition of such
Acquired Shares (any such sale, transfer or disposition of Acquired Shares
occurring within such 18-month period being a "Sale"), Parent shall promptly pay
to the Selling Stockholders (pro rata, in proportion to the number of Acquired
Shares purchased from each Stockholder) an amount in cash equal to the positive
difference (if any) between the aggregate proceeds received by Parent in the
Sale (net of selling commissions, if any) and the aggregate Purchase Price paid
by Parent for the Acquired Shares sold, transferred or disposed of in such Sale.
Parent shall effect any Sale of Acquired Shares only to an unaffiliated party in
a bona fide arm's-length transaction.

                           EXHIBIT 3 TO SCHEDULE 14D-9


                      DIRECTORS MEETINGS AND COMPENSATION

  The Board of Directors held four meetings during the year ended December 31,
1997. Each of the Company's incumbent directors participated in more than 75% of
the meetings of the board and of each committee of the board on which such
person served during such year. Messrs. Frazier and Rohrbach receive a retainer
of $12,000 per annum plus $1,000 for each day on which a board and/or committee
meeting is attended. All directors are reimbursed for expenses incurred in
connection with attendance at meetings.

  Independent directors of the Company may be granted options to purchase up to
100,000 shares in the aggregate of Common Stock of the Company under the
Company's 1994 Director Stock Option Plan (the "Directors' Option Plan"). The
Directors' Option Plan is administered by the non-independent directors of the
Compensation Committee. Options under the Directors' Option Plan are granted at
fair market value at the time of grant and become exercisable within six months
of the grant. On November 24, 1997, options to purchase 1,000 shares were
granted to each of Messrs. Rohrbach and Frazier, with an exercise price of
$17.875 per share.

                                       3

<PAGE>

  The Board of Directors has established an Executive Committee, an Audit
Committee, a Compensation Committee and an Environmental Committee. The
Executive Committee, which consists of Messrs. Brophy, Frieder and Kohlberg,
generally exercises the powers of the Board of Directors when the board is not
in session, subject to the limitations of Delaware law, and has the ability to
approve expenditures of up to $1.0 million. The Audit Committee, which currently
consists of Messrs. Rohrbach, Frieder and Frazier, oversees actions taken by the
Company's independent auditors and recommends the engagement of auditors. The
Compensation Committee, which currently consists of Messrs. Peck, Rohrbach and
Frieder, approves the compensation of executives of the Company, makes
recommendations to the Board of Directors with respect to standards for setting
compensation levels and administers the Company's incentive plans. The
Environmental Committee, which currently consists of Messrs. Frazier, Frieder
and Rohrbach, oversees actions taken by the Company to ensure compliance with
Federal, state and local environmental regulations. During 1997, the Executive
Committee held four meetings, the Audit Committee held two meetings and the
Compensation Committee held two meetings. The Environmental Committee was
created on November 24, 1997 and has not yet held any meetings.

                             CERTAIN RELATIONSHIPS

  Kohlberg & Co. receives an annual management fee of $95,000 from the Company
and will continue to receive such fee through the earlier of (i) October 20,
2002 or (ii) the end of the fiscal year in which the aggregate percentage
ownership of the Common Stock by affiliates of Kohlberg & Co. falls below 20%.
Currently, affiliates of Kohlberg & Co. own approximately 40% of the outstanding
Common Stock of the Company.

  Warner C. Frazier, a director since October 1993, is Chairman and Chief
Executive Officer of Simplicity Manufacturing, Inc., a majority interest in
which is held by an affiliate of Kohlberg & Co. George Brophy is also a director
of Simplicity. In addition, Mr. Brophy is a director of Color Spot, a majority
interest in which is held by an affiliate of Kohlberg & Co.

  John R. Garrett, a nominee for director, is a shareholder of Brownstein,
Hyatt, Farber & Strickland, P.C., one of the Company's outside legal counsel.

  The Company, KABT Acquisition Company, L.P., KABT II Acquisition Company, L.P.
(together with KABT Acquisition Company, L.P., "KABT"), George Brophy, Richard
Parker, William Adams and Donald Grimm are parties to a Stockholders' Agreement,
dated as of October 20, 1992 (the "Stockholders' Agreement") which provides,
among other things, that upon the termination of employment of any manager who
is a party to this agreement, the Company may elect to repurchase (i) the shares
of Common Stock held by such manager at fair market value and the vested options
held by such manager at the excess of fair market value on the date of
termination over the exercise price of such options, if the termination is
without "cause"; or (ii) the shares of Common Stock held by such manager at the
lesser of fair market value on the date of termination or original cost, if the
termination is with "cause." Options held by the manager that are not vested in
the case of (i) and all options in the case of (ii) will be canceled. "Cause"
for purposes of the Stockholders' Agreement means a manager's willful and
repeated failure to comply with the lawful directives of the Board of Directors
or such manager's supervisory personnel or any criminal act or act of
dishonesty, disloyalty, misconduct or moral turpitude by a manager that is
injurious to the property, operations, business or reputation of the Company or
its subsidiaries. The Stockholders' Agreement also provides KABT with rights of
first refusal upon any transfer of Common Stock by the managers party the
agreement other than transfers to such managers' family group and other than
transfers by will or pursuant to applicable laws of descent and distribution.
Holders of a majority of the Common Stock held by managers who are party to the
agreement also have participation rights in the event of a transfer of Common
Stock by KABT. The Stockholders' Agreement provides that if holders of a
majority of the Common Stock approve the sale or other transfer of the Company
to an independent third party, the managers who are party to the agreement will
consent and raise no objections (including exercising any rights or appraisal)
to the sale or transfer of the Company and will take all necessary and desirable
actions in connection with the consummation of such transaction (including
selling their stock if the transfer is structured as a stock transaction),
provided that all holders of Common Stock receive the same consideration per
share in connection with the transaction. The Stockholders' Agreement also
provides demand and piggy-back registration rights to the manager and KABT.

earnings before interest and taxes on both a Company-wide basis and on a
separate basis for the Company's various operations. Participants are divided
into five tiers of participation designed to reflect each participant's sphere
of responsibility within the Company. An individual participant's bonus is
determined as a percentage of base salary (not to exceed 100% effective as of
1994) based upon (i) the relevant performance target(s) achieved, (ii) the
employee's participation tier and (iii) the weighting given to the relevant
performance targets. Bonus amounts are prorated for new participants who are
added during the course of a given year. Bonus payments are subject to
modification at the discretion of the Company's Board of Directors.

SEVERANCE PLAN
  On April 30, 1996, the Board of Directors adopted an executive severance
policy for the benefit of the Company's executive officers (including Messrs.
Brophy, Adams, O'Neill, Parker and Von Behren, providing that, in the event of
termination of an executive officer's employment with the Company for any reason
other than cause or a voluntary termination of employment by the executive
officer (other than a voluntary termination within 90 days of a change in
control), such person shall receive severance compensation equal to 150% of such
person's then-current annual base salary plus 150% of the annual average of such
person's three most recent annual bonuses under the Bonus Plan. A "change in
control" is deemed to occur when (a) a person or group, other than affiliates of
Kohlberg & Co., becomes the beneficial owner, directly or indirectly, of
securities of the Company representing 50% or more of the combined voting power
of the Company's then-outstanding securities and (b) during any period of 24
consecutive months, commencing before or after the event described in clause (a)
above, individuals who at the beginning of such 24-month period were directors
of the Company, or persons whose election to the Board of Directors was approved
by such individuals, cease for any reason to constitute at least a majority of
the Board of Directors. "Cause" is defined as an executive officer's commission
of a felony or other act of dishonesty or moral turpitude resulting in
significant injury to the Company or such person's willful and repeated refusal
to comply with the good faith directives of the Board of Directors or such
person's supervisory personnel.

STOCK OPTION PLANS

  The Company maintains various stock option plans (including the 1994 Employee
Stock Option Plan and the Directors' Option Plan) providing for the issuance of
options to purchase up to an aggregate of 3,100,000 shares of Common Stock
(collectively, the "Stock Option Plans"). As of December 31, 1997, options to
purchase 2,307,325 shares of Common Stock were outstanding under the Stock
Option Plans at exercise prices ranging from $2.50 to $29.50 per share. The
Stock Option Plans are administered by the Compensation Committee of the Board
of Directors. The Compensation Committee determines the terms of the options
granted under the Stock Option Plans (which in certain cases, may be incentive
or nonqualified options), including the exercise price, term (not to exceed ten
years), number of shares and exercisability. The exercise price of options
issued under the Stock Option Plans must equal or exceed the fair market value
of the Common Stock on the date of grant. Payment of the option exercise price
may be made in cash or by a note (at the discretion of the

                                       6

<PAGE>

Committee), by a surrender of shares of Common Stock or a combination of the
foregoing. One of the Stock Option Plans authorizes grants of alternative cash
settlement rights that would entitle participants to receive on exercise of an
option a payment in cash equal to the excess of the then-current fair market
value of the shares with respect to which the option is exercised over the
applicable exercise price. Upon a change in control (as defined in Severance
Plan), all options in the Stock Option Plans will become fully vested.

  The following tables disclose information regarding stock options granted,
exercised during, or held at the end of fiscal 1997 for the named executive
officers pursuant to the Stock Option Plans. The Company has not granted any
stock appreciation rights.

RETIREMENT BENEFITS

  All salaried employees, including executive officers and certain hourly
employees of the Company, participate in a defined benefit pension plan funded
on an actuarial basis entirely by the Company. Although benefits for certain
hourly groups are based on a flat dollar rate multiplied by years of service,
most employees earn an annual pension benefit at age 65 equal to one percent of
their highest five-year average compensation plus three-tenths of one percent of
the amount of such compensation which exceeds "covered compensation" (as defined
in the Internal Revenue Code), all multiplied by years of service not to exceed
35 years. This plan provides for a minimum benefit of one percent of the
employee's average compensation multiplied by the employee's total years of
service. Alternative minimum benefits may be payable to some employees based on
their accruals under prior benefit formulas or predecessor plans.

                                       7

  Certain employees whose benefits under the plan have been reduced as the
result of recent formula changes, or who are otherwise designated by the
Compensation Committee, may accrue additional benefits under supplemental
nonqualified plans which the Company has established.

  The following table shows the projected annual pension benefits payable under
the pension plan at the normal retirement age of 65:

REPORT OF COMPENSATION COMMITTEE

 The Committee

  The three-member Compensation Committee of the Company's Board of Directors is
responsible for annually recommending to the Board of Directors the cash and
stock option compensation payable to the Company's executive officers.
Compensation decisions by the Compensation Committee are submitted to the Board
of Directors for approval.

  The Committee's primary goal is to have the Company's executive officers
compensation program structured and implemented in a manner that recognizes the
Company's need to retain and attract the caliber of executive needed to compete
in the highly competitive business in which it operates.

 Compensation Structure

  The key components of the compensation of the Company's Chief Executive
Officer and other officers are base salary, annual bonus and the issuance of
stock option incentives, from time to time. The objective of the Company is to
create a compensation package that provides both short-term rewards and
long-term incentives for positive individual and corporate performance.

 Base Salaries

  Every other year, based on comparisons with peer group companies and other
industry data, the Chief Executive Officer recommends to the Compensation
Committee base salary adjustments for the officers of the Company. On a periodic
basis, the Chief Executive Officer's base salary is reviewed by the Compensation
Committee and adjusted as deemed necessary. Based on recommendations made by the
Chief Executive Officer and the Compensation Committee the Board of Directors
approved base salary adjustments for the officers of the Company to be effective
January 1, 1998. There were no other base salary increases issued to the Chief
Executive Officer or officers of the Company during 1997.

 Bonuses

  The objective of the Company is to emphasize positive short-term corporate
performance with an annual bonus program. Each of the executive officers (as
well as other key employees) participates in a bonus program that provides for
annual bonus awards contingent on the achievement of certain performance targets
based on earnings before interest and taxes of the Company. The bonus payout is
determined as a percentage of the participant's base salary (not to exceed 100%)
based upon the achievement of targets which are related to the improvement in
earnings as compared to the Company's annual operating plan and prior year's
earnings.

 Stock Options Incentives

  The third component of the Company's executive compensation is comprised of a
stock option plan. Whereas the cash bonus payments are intended to reward for
positive short-term corporate performance, grants under the stock option plan
are intended to provide the executives with longer term incentives which
appreciate in value with the continued favorable future performance of the
Company. Options are granted at fair market value and vest 50% on each of the
second and fourth anniversaries of the grant date of the option and expire 10
years from the date of issuance.

  The Company's executive officers (as well as other key employees) also
participate in the Company's nonqualified defined benefit pension plan.

trustee, officer, employee, adviser, consultant, agent or other representative
of the Company (including, but not limited to, the members of the Committee),
and his or her heirs and legal representatives, against all liability and
expense, including reasonable counsel fees and expenses, amounts paid in
settlement and amounts of judgments, fines, or penalties, incurred or imposed
upon him or her in connection with any claim, action, suit, or proceeding,
whether civil, criminal, administrative, or investigative, in connection with
his or her duties with respect to the administration of this Plan, provided that
such act or omission does not constitute gross negligence or willful misconduct.

                            SECTION 4. MISCELLANEOUS

                  4.1 The Board reserves the right to modify, amend, or
terminate the Plan at any time prior to a Change of Control. Subsequent to a
Change of Control, the Plan may not be modified, amended or terminated in a
manner which would impair or reduce the rights of any Covered Employee. All
modifications of or amendments to the Plan shall be in writing.

                  4.2 Neither the establishment of the Plan nor any designation
or award of Severance Pay hereunder shall be held or construed to confer upon
any person any legal right to continued employment with the Company. The Company
expressly reserves the right to discharge any employee whenever the interest of
the Company,



<PAGE>


in its sole judgment, may so require, without any liability on the part of the
Company, its trustees, officers, employees, advisers, consultants, agents or
other representatives (including, but not limited to, the members of the
Committee), or their respective heirs and legal representatives.

                  4.3 Benefits payable under the Plan shall be subject to
federal and state income tax and social security tax withholdings and any other
withholdings mandated by law and shall be paid out of the general assets of the
Company, and are not required to be funded in any manner, although the Company
in its discretion may set aside amounts in respect of, or fund, benefits payable
hereunder. Benefits payable to a Covered Employee will represent an unsecured
claim by such Covered Employee against the general assets of the Company.

                  4.4 Except to the extent required by law, benefits payable
under the Plan shall not be subject to assignment, alienation, transfer, pledge,
levy, attachment, or other legal process or encumbrance by the Covered Employee
and any attempt to do so shall be void.

                  4.5 SETTLEMENT OF DISPUTES; ARBITRATION. If there has been a
Change of Control and any dispute arises between the Covered Employee and the
Company as to the validity, enforceability and/or interpretation of any right or
benefit afforded by this Plan, at the Covered Employee's option, any other
agreement or policy notwithstanding, such dispute shall be resolved by binding
arbitration proceedings in accordance with the rules of the American Arbitration
Association. The results of any arbitration shall be conclusive on both parties
and shall not be subject to judicial interference or review on any ground
whatsoever.



<PAGE>


                  The Company shall pay the cost of any arbitration proceedings
under this Plan. In the event the Covered Employee brings a claim or is required
to defend in any legal action or other proceeding the validity or enforceability
of any right or benefit afforded by this Plan, the Company will pay any and all
actual legal fees and expenses incurred by the Covered Employee regardless of
the outcome of such action.

                  4.6 This Plan shall be interpreted and applied in accordance
with the laws of the State of New York (without reference to the rules relating
to conflicts of laws), except to the extent superseded by applicable federal
law.
                  4.7 This Plan replaces and supercedes any other severance
policy, plan or arrangement in effect prior to the date listed above with
respect to the Covered Employees.

                                     RELEASE

                                  Introduction

                  Various federal, state and local laws and regulations prohibit
employment discrimination based upon, among other things, age, sex, race, color,
national origin, religion, disability and/or veteran status. These
anti-discrimination laws and regulations are enforced through the United States
Equal Employment Opportunity Commission, the United States Department of Labor,
and various state and local fair employment practices agencies. Other laws and
regulations prohibit employers from terminating employees tortiously or
wrongfully, in breach of express or implied covenants of good faith and fair
dealing, in violation of public policy, or in such a manner as to negligently or
intentionally inflict emotional distress. In other situations, employees may
have claims against an employer for fraud, misrepresentation or defamation.

                  Eligibility for severance pay under the terms outlined in the
Executive Severance Pay Plan of ABT Building Products Corporation (the "Plan")
is contingent upon your signature and delivery of this Release to ABT Building

SUBSEQUENTLY REVOKE THE RELEASE), YOU WILL NOT BE ENTITLED TO ANY SEVERANCE PAY
AWARDED UNDER THE PLAN AND WILL HAVE NO RIGHT TO ANY SEVERANCE PAY AWARDED UNDER
THE PLAN. If you breach the terms of your Release, the Company will be entitled
to the return of any



<PAGE>



Severance Pay you have received and to reimbursement by you of any counsel fees
and expenses incurred by the Company in enforcing such right of return.

                  Under the terms of this Release, you waive any rights to bring
claims against the Company, its trustees, officers, employees, advisers,
consultants, agents and other representatives (including, but not limited to,
the members of the Committee) with respect to employment or other work with the
Company and other matters, except as specifically and expressly allowed by this
Release. This is a legally binding document. DO NOT SIGN THIS RELEASE UNLESS YOU
THOROUGHLY UNDERSTAND IT.

                                     Release

                  Under the Executive Severance Pay Plan of ABT Building
Products Corporation, in exchange for the severance pay of $______ (less the
amount necessary to satisfy applicable withholding requirements (the "Severance
Amount")), I hereby acknowledge that my employment with the Company has
terminated as of ______________*/ and hereby release the Company and all its
past and/or present trustees, officers, employees, advisers, consultants, agents
and other representatives (including, but not limited to, the members of the
Committee), successors and assigns, in their individual and/or representative
capacities (hereinafter together with the Company collectively referred to as
"Company Releasees"), from any and all causes of action, suits, agreements,
promises, damages, disputes, controversies, contentions, differences, judgments,
claims and demands of any kind whatsoever

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

*/ If no date is inserted, the date of your execution of this Release shall be
deemed to be the date of termination of employment.




<PAGE>


("Claims") that I or my heirs, executors, administrators, successors and assigns
ever had, now have or may have against the Company Releasees, whether known or
unknown to me, by reason of my employment and/or cessation of employment with
the Company, or otherwise involving facts that occurred on or prior to the date
that I have signed this Release other than a Claim that the Company has failed
to pay me severance pay in the amount equal to the Severance Amount as awarded
pursuant to the Plan. Such released Claims include, without limitation, any and
all claims under Title VII of the Civil Rights Act of 1964, the Age

any and all Claims under state contract or tort law.

                  I understand that except as provided in Section 2 of the Plan,
my receipt of the Severance Pay will in no way affect any receipt of the
pension, vacation, health care or other benefits to which I am entitled as of my
termination date under any plans, policies or arrangements of the Company in
which I am a participant or in respect of which I am a beneficiary.

                  I understand and agree that I must not disclose the terms of
this Release to anyone other than my spouse, my legal counsel and accountants to
the extent necessary in order to obtain professional advice, that I must
immediately inform my spouse, legal counsel and accountants that they are also
prohibited from disclosing the terms of the Release, and that I must not make
any derogatory allegations about the




<PAGE>





Company Releasees. I further agree to return to the Company any property of the
Company Releasees that I may have, no matter where located, and not to keep any
copies or portions thereof.

                  I represent that I have not filed, and will not hereafter
file, any Claim against the Company Releasees relating to my employment and/or
cessation of employment with the Company, or otherwise involving facts that
occurred on or prior to the date that I have signed this Release, other than a
Claim that the Company has failed to pay me severance pay in the amount equal to
the Severance Amount as awarded pursuant to the Plan.

                  I understand and agree that if I am made a member of a class
in any proceeding relating to a Claim against any Company Releasee, I will opt
out of the class at the first opportunity afforded to me after learning of my
inclusion. In this regard, I agree that I will execute, without objection or
delay, an "opt-out" form presented to me either by the court in which such
proceeding is pending or by counsel for any Company Releasee who is made a
defendant in any such proceeding.

                  I understand and agree that if I commence, continue, join in,
or in any other manner attempt to assert any Claim released herein against the
Company Releasees, or otherwise violate the terms of this Release, the Company
shall have a right to the return of all Severance Pay paid me by the Company
(together with interest thereon), and I shall reimburse the Company for all
counsel fees and expenses incurred by it in defending against such a Claim,
provided that this right of return of such Severance Pay is without prejudice to
the Company's other rights hereunder, including any waiver and release of any
and all Claims against the Company.




<PAGE>



                  I understand and agree that the Company's payment of Severance
Pay to me and my signing of this Release do not in any way indicate that I have
any viable Claims against the Company Releasees or that the Company Releasees
admit any liability to me whatsoever.

                  I have read this Release carefully, have been given at least
twenty-one (21) days to consider all its terms, have been advised to consult an
attorney and any other advisors of my choice, and fully understand that by
signing below I am giving up any right which I may have to sue or bring any
other Claims against the Company Releasees. I have not been forced or pressured
in any manner whatsoever to sign this Release, and I agree to all its terms
voluntarily.

                  I have not relied on any representations, promises or
agreements of any kind made to me in connection with my decision to accept the
severance pay except for those set forth in this Release. I understand that if I
wish, I can consider this Release for at least twenty-one (21) days before I
decide whether to sign it.

                  I understand and agree that this Release will be governed by
New York law. I also agree and understand if one or more of these provisions is
found to be invalid, illegal or unenforceable, that will not affect any other
provisions of this Release.

                  I understand that I have seven (7) days from the date I have
signed this Release below to revoke this Release, that this Release will not
become effective until the eighth (8th) day following the date that I have
signed this Release, and that the

Company will have no obligation to pay me the severance pay set forth in this

comments:

"I'm pleased that we will be associated with Louisiana-Pacific for the following
reasons:

o        The offer is a fair one that the Board considered carefully. It is also
         risk free in that only cash is involved.

o        We have some significant growth strategies and financing of these
         important plans will be made easier as part of Louisiana-Pacific.

o        The marriage is good in that separately, Louisiana-Pacific and ABT
         Building Products have developed outstanding technology in the
         engineered wood field. with the exchange of technology, the combined
         entity will be world class.

o        The opportunities provided our people was a positive factor. They will
         have a much bigger universe to expand their personal careers. It is a
         good meld of cultures and we frankly like the integrity and style of
         the people at Louisiana- Pacific."

                                                                January 19, 1999
 
The Board of Directors
ABT Building Products Corporation
One Neenah Center, Suite 600
Neenah, Wisconsin 54956
 
Gentlemen:
 
    You have requested our opinion as to the fairness, from a financial point of
view, of the consideration to be paid to the holders (the "Shareholders") of
common stock, par value $0.01 per share (the "Common Stock") of ABT Building
Products Corporation (the "Company") in connection with the proposed acquisition
(the "Acquisition") of the Company by Striper Acquisition, Inc., a wholly owned
subsidiary (the "Acquisition Subsidiary") of Louisiana-Pacific Corporation
("Acquiror"). Pursuant to the terms of an agreement and plan of merger among the
Company, the Acquiror and the Acquisition Subsidiary (the "Merger Agreement"),
the Shareholders will receive $15.00 in cash (the "Consideration") in exchange
for each share of Common Stock. The terms and conditions of the Acquisition are
more fully set forth in the Merger Agreement dated as of January 19, 1999. We
understand that the Acquisition is to be effected in a two-step transaction, the
first step of which will be a cash tender offer (the "Tender Offer") by the
Acquisition Subsidiary for all outstanding shares of Common Stock at a per share
price of $15.00 net to the seller in cash upon the terms and conditions set
forth in the Merger Agreement. We further understand that each share of Common
Stock not acquired in the Tender Offer will be converted, in a subsequent merger
of the Acquisition Subsidiary with and into the Company, into the right to
receive $15.00 in cash.
 
    Warburg Dillon Read LLC ("WDR") and its predecessors have rendered financial
advisory services to the Company, affiliates of Kohlberg & Company, LLC (a
significant shareholder of the Company) ("Kohlberg") and Acquiror from time to
time and have received customary fees in connection with certain of such
services rendered. In addition, WDR will receive a fee for services provided in
connection with its opinion. In the ordinary course of business, WDR, its
successors and affiliates may have traded securities of the Company or Acquiror
for their own accounts and for the accounts of customers 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 Acquisition. In addition, 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
Acquisition. WDR has not been requested, nor did we, solicit other third party
indications of interest in acquiring the Company. In rendering this opinion, we
have assumed, with your consent, that the Company and Acquiror will comply with
all the materials terms of the Merger Agreement.
 
    In arriving at our opinion, we have, among other things: (i) reviewed
certain publicly available business and financial information relating to the
Company; (ii) reviewed the historical price and trading activity for the shares
of common stock of the Company; (iii) reviewed certain internal financial
information and other data provided to us by the Company relating to the
business and prospects of the Company, including, but not limited to, (a)
financial projections prepared by management of the Company, (b) pro forma
financial results for the pending sale of the Company's fiber cement operations,
and (c) financial data for certain of the Company's product lines, much of which
information is not publicly available; (iv) conducted discussions with members
of the senior management of the Company, including, but not limited to,
discussions concerning the Company's pending product liability litigation; (v)
reviewed the financial terms, to the extent publicly available, of certain
acquisition transactions which we considered relevant; (vi) reviewed publicly
available financial and securities market data pertaining to certain publicly
held companies in lines of business which we believed to be generally comparable
to those of the Company; and (vii) conducted such other financial studies,
analyses and investigations, and considered such other information as we deemed
necessary or appropriate.
<PAGE>
    In connection with our review, with your consent, we have not assumed any
responsibility for independent verification of any of the foregoing information
and have relied upon its being complete and accurate in all material respects.
We have not been requested to and have not made an independent evaluation or
appraisal of any assets or liabilities (contingent or otherwise) of the Company
or any of its subsidiaries, nor have we been furnished with any such evaluation
or appraisal. We have relied, with your consent, upon Company management's
estimates of the proposed settlement and resolution costs with respect to
pending product liability litigation. Similarly, we have not reviewed or
investigated the pending sale of the Company's fiber cement operations, and have
relied, with your consent, on Company management for such information and the
estimated effects on the Company of such transaction. Further, we have assumed,
with your consent, that all of the information, including the projections
provided to us by the Company's management, was prepared in good faith and was
reasonably prepared on a basis reflecting the best currently available estimates
and judgments of the Company's management as to the future financial performance
of the Company, and was based upon the historical performance and certain
estimates and assumptions which were reasonable at the time made. In addition,
our opinion is based on economic, monetary and market conditions existing on the
date hereof.
 
    It is understood that the opinion expressed herein is provided for the
information of the Board of Directors in their evaluation of the Acquisition,
and our opinion is not intended to be and does not constitute a recommendation
as to whether or not any Shareholder should tender shares of Common Stock
pursuant to the Tender Offer or otherwise participate in the Acquisition
pursuant to the terms of the Merger Agreement.
 
    Based upon and subject to the foregoing, we are of the opinion that, as of
the date hereof, the per share Consideration to be paid to the Shareholders for
Common Stock in connection with the Acquisition is fair, from a financial point
of view, to such Shareholders.
 
                                  Very truly yours,
 
                                  WARBURG DILLON READ LLC
