Common Stock (calculated as described in Annex A), but less than 90% of the
voting power of the then issued and outstanding shares of Common Stock.  Parent

disseminating the Schedule 14D-9 with the appropriate Offer Documents to the
Company's stockholders.  Each of the Company, Parent and Sub agrees promptly to
correct any information provided by it for use in the Schedule 14D-9 if and to
the extent that such information shall have become false or misleading in any
material respect, and the Company further agrees to take all steps necessary to
amend or supplement the Schedule 14D-9 and to cause the Schedule 14D-9 as so
amended or supplemented to be filed with the SEC and disseminated to the
Company's stockholders, in each case as and to the extent required by applicable
federal securities laws.  Parent and its counsel shall be given reasonable
opportunity to review and comment upon the Schedule 14D-9 prior to its filing
with the SEC or dissemination to stockholders of the Company.  The Company
agrees to provide Parent and its counsel any comments the Company or its counsel
may receive from the SEC or its staff with respect to the Schedule 14D-9
promptly after the receipt of such comments.

     (c)  In connection with the Offer, the Company shall cause its transfer
agent to furnish Sub promptly with mailing labels containing the names and
addresses of the record holders of Shares as of a recent date and of those
persons becoming record holders subsequent to such date, together with copies of
all lists of stockholders, security position listings and computer files and all
other information in the Company's

possession or control regarding the beneficial owners of Shares, and shall
furnish to Sub such information and assistance (including updated lists of
stockholders, security position listings and computer files) as Parent or Sub
may reasonably request in communicating the Offer to the Company's stockholders.
Subject to the requirements of applicable law, and except for such steps as are
necessary to disseminate the Offer Documents and any other documents necessary
to consummate the Merger, Parent and Sub and their affiliates, associates and
agents shall hold in confidence the information contained in any such labels,
listings and files, will use such information only in connection with the Offer
and the Merger and, if this Agreement shall be terminated, will promptly, upon
request, deliver to the Company or destroy, and will use their reasonable best
efforts to cause their affiliates, associates and agents to deliver or destroy,
all copies of such information then in their possession or control.

amount of cash into which the Shares theretofore represented by such Certificate
shall have been canceled and become the right to receive pursuant to Section
                                                                     -------

event of a transfer of ownership of Shares that is not registered in the
transfer records of the Company, payment may be made to a person other than the
person in whose name the Certificate so surrendered is registered, if such
Certificate shall be properly endorsed or otherwise be in proper form for
transfer and 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 such Certificate or establish to the satisfaction of the Surviving
Corporation that such tax has been paid or is not applicable.  Until surrendered
as contemplated by this Section 3.2, each Certificate (other than Certificates

any Certificate.  Parent or the Paying Agent shall be entitled to deduct and
withhold from the consideration otherwise payable pursuant to this Agreement to
any holder of Shares such amounts as Parent or the Paying Agent is required to
deduct and withhold with respect to the making of such payment under the Code
(as hereinafter defined) or under any provision of state, local or foreign tax
law.  To the extent that amounts are so withheld by Parent or the Paying Agent,
such withheld amounts shall be treated for all purposes of this Agreement as
having been paid to the holder of the Shares in respect of which such deduction
and withholding was made by the Parent or the Paying Agent.

     (c)  No Further Ownership Rights in Shares.  All cash paid upon the

shares of stock theretofore represented by such Certificates.  At the Effective
Time, the stock transfer books of the Company shall be closed, and there shall
be no further registration of transfers on the stock transfer books of the
Surviving Corporation of the shares of Common Stock that were outstanding
immediately prior to the Effective Time.  If, after the Effective Time,
Certificates are presented to the Surviving Corporation or the Paying Agent for
any reason, they shall be canceled and exchanged as provided in this Article
                                                                     -------

     SECTION 4.12  Benefit Plans; Employees and Employment Practices.  (a)
                   -------------------------------------------------       
Except as disclosed in the Company Filed SEC Documents and item 4.12(a) of the
Company Letter, since the date of the most recent audited financial statements
included in the Company Filed SEC Documents, there has not been any adoption or
amendment in any material respect (including any increase or improvements in
benefits or coverage) by the Company or any of its Subsidiaries of any
collective bargaining agreement or any bonus, pension, profit sharing, deferred
compensation, incentive compensation, stock ownership, stock purchase, stock
option, phantom stock, retirement, vacation, severance, disability, death
benefit, hospitalization, medical, fringe benefit, excess, supplemental
executive compensation, employee stock purchase, stock appreciation, restricted
stock or other material employee benefit plan, policy, arrangement or
understanding (whether or not in writing) providing benefits to any current or
former employee, officer or director of the Company or any of its Subsidiaries
(collectively, the "Benefit Plans").  To the Company's knowledge, except as
                    -------------                                          
disclosed in item 4.12(a) of the Company Letter or in the Company Filed SEC
Documents, there exist no material employment, consulting, severance,
termination or indemnification agreements between the Company or any of its
Subsidiaries and any current or former employee, officer or director of the
Company or any of its Subsidiaries.

     (b)  Item 4.12(b) of the Company Letter contains a list of all "employee
pension benefit plans" (as defined in

                                      -18-
<PAGE>
 
Section 3(2) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA") (sometimes referred to herein as "Pension Plans") and "employee
  -----                                     -------------                
welfare benefit plans" (as defined in Section 3(1) of ERISA) maintained,
sponsored or contributed to, by the Company or any of its U.S. or foreign
Subsidiaries for the benefit of any current or former employees, officers or
directors of the Company or any of such Subsidiaries (collectively, the "ERISA
                                                                         -----
Benefit Plans").  The Company has made available to Parent true, complete and
- -------------                                                                
correct copies of (i) each ERISA Benefit Plan (or, in the case of any unwritten
ERISA Benefit Plans, descriptions thereof), (ii) the most recent annual report
on Form 5500 (and related schedules and financial statements or opinions
required in connection therewith) filed with the Internal Revenue Service with
respect to each ERISA Benefit Plan (if any such report was required), (iii) the
most recent actuarial report with respect to each ERISA Benefit Plan, as
applicable, (iv) the most recent summary plan description (and a summary of
material modifications, if applicable) for each ERISA Benefit Plan and (v) each
trust agreement and group annuity contract relating to any ERISA Benefit Plan.

     (c)  Except as disclosed in item 4.12(c) of the Company Letter, all Pension
Plans which are intended to be tax-qualified have received determination letters
in respect of such Pension Plans from the Internal Revenue Service to the effect
that such Pension Plans are qualified and exempt from Federal income taxes under
Section 401(a) and 501(a), respectively, of the Code, and, to the best knowledge
of the Company, there is no reason why any such Pension Plan is not currently so
qualified, where such revocation or failure to so qualify would be reasonably
expected to have a Material Adverse Effect.

     (d)  Except as disclosed in item 4.12(d) of the Company Letter, each
Benefit Plan has been administered in all material respects in conformity with
its terms and the applicable requirements of ERISA and the Code and other
applicable laws and all contributions required to be made have been made in
accordance with the provisions of each such Benefit Plan and with ERISA and the
Code and other applicable laws, where the failure to comply or to make the
required contributions would be reasonably expected to have a Material Adverse
Effect on the Company.

     (e)  None of the Company or any of its Subsidiaries, or any other person or
entity that, together with the Company, is treated as a single employer under
Section 414 of the Code (an "ERISA Affiliate"), currently maintains or has
                             ---------------                              
maintained during the five-year period preceding the date hereof any
"multiemployer plan" (within the meaning of Section 3(37) of ERISA), or has
incurred any liability under Title IV of ERISA or to the Pension

                                      -19-
<PAGE>
 
Benefit Guaranty Corporation (other than contributions and premiums in the
ordinary course) that has not been fully paid as of the date hereof, which would
be reasonably expected to have a Material Adverse Effect on the Company.  To the
Company's knowledge, none of the Company, any of its Subsidiaries, any officer
of the Company or any of its Subsidiaries or any of the Benefit Plans which are
subject to ERISA, including the Pension Plans, any trusts created thereunder or,
to the knowledge of the Company, any trustee or administrator thereof, has
engaged in a "prohibited transaction" (as such term is defined in Section 406 of
ERISA or Section 4975 of the Code) or any other breach of fiduciary
responsibility that could reasonably be expected to subject the Company, any of
its Subsidiaries or any officer of the Company or any of its Subsidiaries to any
material tax or penalty on prohibited transactions imposed by such Section 4975
or to any material liability under Section 502(i) or (l) of ERISA, where the
liability that would be reasonably expected to occur would have a Material
Adverse Effect on the Company.  With respect to each Pension Plan subject to
Title IV of ERISA (other than a multiemployer plan within the meaning of Section
3(37) of ERISA) (i) no proceeding has been initiated to terminate such plan,
(ii) there has been no "reportable event" (as such term is defined in Section
4043(b) of ERISA), (iii) no "accumulated funding deficiency" (within the meaning
of Section 412 of the Code), whether or not waived, has occurred, (iv) no person
has failed to make a required installment or any other payment required under
Section 412 of the Code before the applicable due date and (v) neither the
Company nor any ERISA Affiliate has provided or is required to provide security
to such plan under Section 401(a)(29) of the Code due to a plan amendment that
results in an increase in current liability, where the liability, individually
or in the aggregate, that would be reasonably expected to result would have a
Material Adverse Effect on the Company.

     (f)  There is no dispute, arbitration, claim, suit or grievance, pending or
threatened, involving a Benefit Plan (other than routine claims for benefits
payable under any such plan), and to the knowledge of the Company, there is no
basis for any such claim, which would reasonably be expected to have a Material
Adverse Effect on the Company.

     (g)  Except as disclosed in item 4.12(g) of the Company Letter, there are
no controversies, strikes, work stoppages or disputes pending or threatened
between the Company or any of its Subsidiaries and any current or former
employees, and, to the Company's knowledge, no organizational effort by any
labor union or other collective bargaining unit currently is under way or
threatened with respect to any employee, which would reasonably be expected to
have a Material Adverse Effect on the Company.  A

true, complete and correct copy of any applicable collective bargaining

Letter or in the Company Filed SEC Documents, there is no suit, claim, action,
proceeding or investigation pending or, to the knowledge of the Company,
threatened against the Company or any of its Subsidiaries that would reasonably
be expected to have a Material Adverse Effect on the Company or prevent or
result in a third party materially delaying the consummation of the Offer and/or
the Merger.  Except as disclosed in item 4.13 of the Company Letter or in the
Company Filed SEC Documents, neither the Company nor any of its Subsidiaries is
subject to any outstanding judgment, order, writ, injunction or decree that
would reasonably be expected to have a Material Adverse Effect on the Company or
prevent or result in a third party materially delaying the consummation of the
Offer and/or the Merger.

     SECTION 4.14  Environmental Matters.  Except as set forth in the Company

or disposed of any Hazardous Substances (as defined below) on, under, from or at
any of the Company's or any of its Subsidiaries' properties or any other

individually or in the aggregate, reasonably be expected to result in a Material
Adverse Effect on the Company, (ii) any knowledge of the presence of any
Hazardous Substances that have been released into the environment on, under or
at any of the Company's or any of its Subsidiaries' properties other than that
which would not reasonably be expected to result in a Material Adverse Effect on

applicable statute, law, ordinance, regulation, rule, judgment, decree or order
of any Governmental Entity relating to any matter of pollution, protection of
the environment or environmental regulation or control or regarding Hazardous

settled with the relevant Governmental Entity, (B) of the institution or
pendency of any suit, action, claim, proceeding or investigation by any
Governmental Entity or any third party in connection with any such violation,
(C) requiring the response to or remediation of Hazardous Substances at or
arising from any of the Company's or any of its Subsidiaries' properties or any
other properties, (D) alleging noncompliance by the Company or any of its
Subsidiaries with the terms of any permit required under any Environmental Law
in any manner reasonably likely to require

material expenditures or to result in material liability or (E) demanding
payment for response to or remediation of Hazardous Substances at or arising
from any of the Company's or any of its Subsidiaries' properties or any other
properties, except in each case for the notices set forth in item 4.14 of the
Company Letter and except in each case for notices that would not, individually
or in the aggregate, reasonably be expected to result in a Material Adverse
Effect on the Company.  For purposes of this Agreement, the term "Hazardous
                                                                  ---------

4.12(a) or 4.15 of the Company Letter or the Company Filed SEC Documents,
neither the Company nor any of its Subsidiaries is a party to any Benefit Plan,
any of the benefits of which will be increased, or the vesting of the benefits
of which will be accelerated, by the occurrence of any of the transactions
contemplated by this Agreement or the value of any of the benefits of which will
be calculated on the basis of any of the transactions contemplated by this
Agreement, where the liability that would reasonably be expected to result would
have a Material Adverse Effect.

     SECTION 4.16  Asbestos Litigation Matters.  (a)  Except as disclosed in
                   ---------------------------                              
item 4.16 of the Company Letter, to its knowledge, neither the Company nor its
insurance carriers is a party to agreements or commitments for the resolution of
asbestos personal injury claims or lawsuits, or for the payment of settlement
monies, fees, disbursements or costs in connection therewith, which would be
binding upon the Company in the event of Global Court Disapproval (as defined in
the Global Settlement Agreement dated December 23, 1993, among the Company,
Continental Casualty Company ("Continental"), CNA Casualty Company of California
                               -----------

available after the Trigger Date pursuant to Section 2.3 of the Trilateral
Settlement Agreement, which would exceed $15 million in the aggregate as finally
determined.

     (b) Except as disclosed in item 4.16 of the Company Letter, to the
Company's knowledge, there is no judgment which provides that it modifies the
terms of Global Approval Judgment (as defined in the Global Settlement Agreement

Company), and as affirmed by the United States Court of Appeals for the Fifth
Circuit in In re Asbestos Litigation, 90 F.3d 963 (1996), and there is no

Approval Judgment.  In the event of Global Approval Judgment, under the terms of
that judgment the Company shall have no further liability for Personal Injury
Asbestos Claims by persons who are members of the Global Settlement Class or of
the Global Third Party Claimant Class, save and except any liability resulting
from a collateral attack on Global Approval Judgment, or from an inability to
enforce Global Approval Judgment according to its terms, or as described in item
4.16 of the Company Letter.  Continental Casualty Company is a party to an
agreement with the Company which provides that if Global Approval Judgment is
entered, then on and after the date of such approval, Continental shall pay
indemnity and defense costs with respect to Unsettled Present Claims that are
not Global Class Claims, and shall pay settlement amounts on Presently Settled
Claims when the same become due and payable that are not Global Class Claims.
"Unsettled Present Claims" shall include claims of individuals for asbestos-
related personal injuries brought against the Company in lawsuits filed prior to
the time after which claims are in fact included within the Global Settlement
(and which are not Presently Settled Claims).  "Presently Settled Claims" shall
include claims of individuals for asbestos-related personal injuries that do not
fall within the class of claims covered by the Global Settlement and that as of
August 23, 1993 had been settled.

     (c) The consummation of the merger set forth in this Agreement in
accordance with its terms is not a breach of, and will not result in a material
forfeiture of rights under, the terms of (i) the Global Settlement Agreement or
any of the exhibits to the Global Settlement Agreement, including, without
limitation, the Glossary of Terms (Exhibit A), the Fibreboard Asbestos
Compensation Trust Agreement (Exhibit B), the Trust Distribution Process (Annex

Company, Continental, CNA, Columbia and Pacific (the "Trilateral Settlement

the Company and Continental; and (iv) the Settlement Agreement, dated as of
August 5, 1993, as heretofore amended, among the Company, Continental and Ness
Motley Loadholt Richardson & Poole and certain of its affiliate law firms.

     (d) To the Company's knowledge, and subject to the assumptions and
calculations set forth in Section 4.16 of the Company Letter, in the event of
Global Court Disapproval, if the Trigger Date (as defined in the Trilateral
Settlement Agreement) were June 30, 1997, the projected amount to be made

million payment obligation of the Company as described in Section 2.3(D)(2) of
the Global Settlement Agreement, approximately $9.89 million of such obligation
has been fully funded by The Home Insurance Company, and the Company's future
obligation thereunder is limited to the payment of approximately $110,000 plus
interest at 3.085% from January 1, 1994 through the date of Global Approval
Judgment, together with interest on the sum of $10.0 million at the rate of
3.085% from August 27, 1993 to December 31, 1993.

                  ---------------                                    
direct and use its best efforts to cause its officers, directors, employees,

with any parties that may be ongoing with respect to a Takeover Proposal (as
hereinafter defined).  The Company shall not, nor shall it permit any of its
Subsidiaries to, nor shall it authorize or permit any of its officers, directors
or employees or any investment banker, financial advisor, attorney, accountant
or other representative retained by it or any of its Subsidiaries to, directly

furnishing information) any inquiries or the making of any proposal which
constitutes, or may reasonably be expected to lead to, any Takeover Proposal or

payment of Shares pursuant to the Offer, the Board of Directors of the Company
determines in good faith, after consultation with outside counsel, that it would
be consistent with its fiduciary responsibilities to the Company's stockholders
under applicable law, the Company may, in response to a Takeover Proposal which
was not solicited subsequent to the date hereof, and subject to compliance with
Section 6.2(c), (x) furnish information with respect to the Company to any
- --------------                                                            
person pursuant to a confidentiality agreement in substantially the same form as
the confidentiality agreement entered into between the Company and Parent (other
than for provisions similar to Section 6 thereof) and (y) participate in
discussions, investigations and/or negotiations regarding such Takeover
Proposal.  Without limiting the foregoing, it is understood that any violation
of the restrictions set forth in the preceding sentence by any director or
executive officer of the Company or any of its Subsidiaries, whether or not such
person is purporting to act on behalf of the Company or any of its Subsidiaries
or otherwise, shall be deemed to be a breach of this Section 6.2(a) by the
                                                     --------------

                                           -----------------                    
proposal or offer from any person relating to any direct or indirect acquisition
or purchase of 20% or more of the aggregate assets of the Company and its
Subsidiaries, taken as a whole, or 20% or more of the voting power of the shares
of Common Stock then outstanding or any tender offer or exchange offer that if
consummated would result in any person beneficially owning 20% or more of the
voting power of the shares of Common Stock then outstanding or any merger,
consolidation, business combination, recapitalization, liquidation, dissolution
or similar transaction involving the Company, other than the transactions
contemplated by this Agreement.

     (b)  Except as set forth in this Section 6.2, neither the Board of
                                      -----------

shall (i) withdraw or modify, or propose publicly to withdraw or modify, in a
manner adverse to Parent, the approval or recommendation by such Board of
Directors or such committee of the Offer, the Merger or this Agreement; provided
                                                                        --------
that, the Board of Directors may, (A) in response to any Takeover Proposal,
suspend such recommendation for a period of up to 24 hours pending its analysis
of such Takeover Proposal or (B) at any time prior to the consummation of the
Offer, modify or withdraw such recommendation if the Board of Directors of the
Company determines in good faith, after consultation with outside counsel, that
it would be consistent with its fiduciary responsibilities to so modify or
withdraw such recommendation (regardless of the existence of a Superior Proposal
(as defined below) at such time); provided further that, unless this Agreement
                                  -------- -------                            
shall have been terminated, any such suspension, modification or withdrawal
shall not prevent Parent and Sub, in its or their discretion, from consummating
the Offer and shall not affect any of the actions taken by the Company pursuant
to Section 4.17 of this Agreement, (ii) approve or recommend, or propose
   ------------

Company to enter into any letter of intent, agreement in principle, acquisition
agreement or other similar agreement (each, an "Acquisition Agreement") related
                                                ---------------------          
to any Takeover Proposal.  Notwithstanding the foregoing, in the event that
prior to the acceptance for payment of Shares pursuant to the Offer the Board of
Directors of the Company determines in good faith, after consultation with
outside counsel, that it would be consistent  with its fiduciary
responsibilities to the Company's stockholders under applicable law, the Board
of Directors of the Company may (subject to this and the following sentences)
withdraw or modify its approval or recommendation of the Offer, the Merger and
this Agreement, approve or recommend a Superior Proposal (as defined below) or
terminate this Agreement, but in each case, only at a time that is after the
second business day following Parent's receipt of written notice (a "Notice of
                                                                     ---------
Superior Proposal") (which obligation may be satisfied by the delivery of the

notice required by Section 6.2(c)) advising Parent that the Board of Directors
                   --------------                                             
of the Company has received a Takeover Proposal that may constitute a Superior
Proposal, specifying the material terms and conditions of such Superior Proposal
and identifying the person making such Superior Proposal.  For purposes of this
Agreement, a "Superior Proposal" means any proposal determined by the Board of
              -----------------                                               
Directors of the Company in good faith, after consultation with outside counsel,
to be a bona fide proposal and made by a third party to acquire, directly or
indirectly, for consideration consisting of cash, property and/or securities,
more than 50% of the combined voting power of the shares of Common Stock then
outstanding or all or substantially all the assets of the Company and otherwise
on terms which the Board of Directors of the Company determines in

                                      -34-
<PAGE>
 
its good faith judgment, after consultation with outside counsel and with a
financial advisor of nationally recognized reputation (such as Dillon Read), to
be more favorable to the Company's stockholders than the Offer and the Merger.

          (c)  In addition to the obligations of the Company set forth in
paragraphs (a) and (b) of this Section 6.2, the Company shall promptly advise
                               -----------                                   
Parent orally and in writing of any request for information or of any Takeover
Proposal, the material terms and conditions of such request or Takeover Proposal
and the identity of the person making such request or Takeover Proposal. The
Company will endeavor to keep Parent reasonably informed of the overall status
of any such request or Takeover Proposal.

          (d)  Nothing contained in this Section 6.2 shall prohibit the Company
                                         -----------                           
from taking and disclosing to its stockholders a position contemplated by Rules
14d-9 and 14e-2 promulgated under the Exchange Act or from making any disclosure
to the Company's stockholders if, in the good faith judgment of the Board of
Directors of the Company, after consultation with outside counsel, such
disclosure is necessary in order to comply with its fiduciary duties to the
Company's stockholders under applicable law or is otherwise required under
applicable law.

          SECTION 6.3  Third Party Standstill Agreements.  During the period
                       ---------------------------------                    
from the date of this Agreement through the Effective Time, the Company shall
not terminate, amend, modify or waive any provision of any confidentiality or
standstill agreement to which the Company or any of its Subsidiaries is a party
(other than any involving Parent) unless the Company's Board of Directors shall
have determined in good faith, after consultation with outside counsel, that
failing to release any third party or to amend, modify or waive such provisions
would not be consistent with the Company's Board of Directors' fiduciary
responsibilities under applicable law.

          SECTION 6.4  Disclosure to Parent.  (a)  The Company shall promptly
                       --------------------                                  
advise Parent orally and in writing if there occurs, to the knowledge of the
Company, any change or event which results in the executive officers of the
Company having a good faith belief that such change or event has resulted in or
is reasonably likely to result in a Material Adverse Effect on the Company or
will prevent or result in a third party materially delaying the consummation of
the Offer or the Merger.  The Company shall provide to Parent, and Parent shall
provide to the Company, copies of all filings made by the Company or Parent, as
the case may be, with any Governmental Entity in connection with this Agreement
and the transactions contemplated hereby.

keep Parent and its advisors reasonably apprised of developments in the asbestos
personal injury litigation, including, without limitation, developments relating

of Texas; and (ii) consult with Parent and its advisors concerning positions to
be taken by the Company or its Subsidiaries in the asbestos personal injury
litigation, including, without limitation, matters relating to any of the
Asbestos Agreements or to the Ahearn or Rudd settlement class actions; provided,

the consent of the counterparty thereto, which consent the Company shall seek
upon the request of either Parent or Sub, or to provide information subject to
privilege.

                       ------------------------------                         
the date of this Agreement until such time as Parent's designees shall
constitute a majority of the Board of Directors of the Company, without the
prior written consent of Parent, neither the Company nor any of its Subsidiaries
shall take or omit any action, which action or omission would materially
prejudice the position of the Company or any of its Subsidiaries in the asbestos
personal injury litigation or in the Ahearn or Rudd settlement class actions or
                                     ------    ----                            
under any of the Asbestos Agreements.

equal to (i) the product of (x) the number of shares of Common Stock subject or
related to such Option and (y) the excess, if any, of the Merger Consideration
over the exercise or purchase price per share of Common Stock subject or related
to such Option, minus (ii) all applicable federal, state and local taxes
required to be withheld by the Company.  The Company shall use its reasonable
best efforts to ensure that, after giving effect to the foregoing, no Option
shall be exercisable for Common Stock of the Company following the consummation
of the Offer.

          (b)  Each restricted stock agreement or stock unit agreement which is
outstanding immediately prior to the consummation of the Offer pursuant to any

whether or not otherwise exercisable, shall become fully vested. Upon the
consummation of the Offer each such agreement shall be canceled by the Company
in return for the payment as hereinafter provided for which the holder thereof
shall thereupon be entitled to receive.  Each such holder shall receive promptly
(but in no event later than five days) after the consummation of the Offer, a
cash payment in respect of such cancellation from the Company in an amount equal
to (i) the product of (x) the number of shares of Common Stock subject or
related to such agreement and (y) the Merger Consideration, minus (ii) all
applicable federal, state and local taxes required to be withheld by the
Company.  The Company shall use its reasonable best efforts to ensure that,
after giving effect to the foregoing, no such agreement shall be outstanding
following the consummation of the Offer.

          (c)  No further awards of any type shall be made under any Company
Stock Plan after the date of this Agreement.

          SECTION 7.5  Public Announcements.  Parent and the Company will
                       --------------------                              
consult with each other before issuing any press release or otherwise making any
public statements with respect to the transactions contemplated by this
Agreement 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, fiduciary duties or by obligations pursuant to any listing agreement with
any national securities exchange.

          SECTION 7.6  Real Estate Transfer Tax.  Parent and the Company agree
                       ------------------------                               
that either the Surviving Corporation or Parent (without any liability to any of
the Company's stockholders) will pay any state or local tax which is
attributable to the transfer of the beneficial ownership of the Company's or its
Subsidiaries' real property, if any (collectively, the "Transfer Taxes"), and
                                                        --------------       
any penalties or interest with respect to the Transfer Taxes, payable in
connection with the consummation of the Offer and the Merger.  The Company
agrees to cooperate with Parent in the filing of any returns with respect to the
Transfer Taxes, including supplying in a timely manner a complete list of all
real property interests held by the Company and its Subsidiaries and any
information with respect to such property that is reasonably necessary to
complete such returns.  The portion of the consideration allocable to the real
property of the Company and its Subsidiaries shall be determined by Parent in
its reasonable discretion.  To the extent permitted by law, the stockholders of
the Company shall be deemed to have agreed to be bound by the allocation
established pursuant to this Section 7.6 in the preparation of any return with
                             -----------                                      
respect to the Transfer Taxes.

          SECTION 7.7  State Takeover Laws.  If any "fair price" or "control
                       -------------------                                  
share acquisition" statute or other similar statute or regulation shall become
applicable to the transactions contemplated hereby, Parent and the Company and
their respective Boards of Directors shall use their reasonable best efforts to
grant such approvals and take such actions as are necessary so that the
transactions contemplated hereby may be consummated as promptly as practicable
on the terms contemplated hereby and otherwise act to minimize the effects of
any such statute or regulation on the transactions contemplated hereby.

          SECTION 7.8  Indemnification; Directors and Officers Insurance.  From
                       -------------------------------------------------       
and after the Effective Time, Parent agrees that it will and will cause the
Surviving Corporation to exculpate, indemnify and hold harmless all past and
present employees, officers, agents and directors of the Company and its
Subsidiaries (the "Indemnified Parties") to the same extent such persons are
                   -------------------                                      
currently exculpated and indemnified by the Company pursuant to the Company's
Certificate of Incorporation and By-Laws for acts or omissions occurring at or
prior to the Effective Time and will cause the Surviving Corporation's
Certificate of Incorporation and By-Laws to continue to include provisions to
such effect.  Parent shall cause the Surviving Corporation to provide, for an
aggregate period of not less than six years from the Effective Time, the
Company's directors and officers who are currently covered by the Company's
existing insurance and indemnification policy an insurance and indemnification
policy that provides coverage for events occurring prior to the Effective Time
(the "D&O Insurance") that is no less favorable than the Company's existing
      -------------                                                        
policy or, if substantially equivalent insurance coverage is unavailable, the
best available coverage; provided, however, that the Surviving Corporation shall
                         --------  -------                                      
not be required to pay an annual premium for the D&O Insurance in excess of 250
percent of the last annual premium paid prior to the date hereof (which the
Company represents and warrants to be $400,250), but in such case shall purchase
as much coverage as possible for such amount.

          SECTION 7.9  Notification of Certain Matters.  Parent shall give
                       -------------------------------                    
prompt notice to the Company, and the Company shall give prompt notice to
Parent, of:  (i) the occurrence, or non-occurrence, in each case, to the
knowledge of the Company or Parent, as the case may be, of any event the
occurrence, or non-occurrence, of which results in the executive officers of the
Company or Parent, as the case may be, having a good faith belief that such
change or event would be reasonably likely to cause (x) any representation or
warranty of such entity contained in this Agreement that is not qualified as to
materiality to be untrue or inaccurate in any material respect, (y) any
representation or warranty of such entity contained in this Agreement that is

                                      -41-
<PAGE>
 
qualified as to materiality to be untrue or inaccurate in any respect, or (z)
any covenant, condition or agreement of such entity contained in this Agreement
not to be complied with or satisfied in all material respects; and (ii) the
executive officers of the Company or Parent, as the case may be, believing in
good faith that the Company or Parent, as the case may be, has, to the knowledge
of the Company or Parent, as the case may be, failed to comply with in all
material respects or satisfy in all material respects any covenant, condition or
agreement of such entity to be complied with or satisfied by it hereunder;
                                                                          
provided, however, that the delivery of any notice pursuant to this Section 7.9
- --------  -------                                                   -----------
shall not limit or otherwise affect the remedies available hereunder to the
party receiving such notice.

purchases Shares pursuant to the Offer (but subject to the satisfaction of the
Minimum Condition), Sub shall be entitled, to the fullest extent permitted by
law, to designate at its option up to that number of directors, rounded to the
nearest whole number, of the Company's Board of Directors, subject to compliance
with Section 14(f) of the Exchange Act, as will make the percentage of the
Company's directors designated by Sub equal to the aggregate voting power of the
shares of Common Stock held by Parent or any of its Subsidiaries; provided,
                                                                  -------- 
however, that in the event that Sub's designees are elected to the Board of
- -------                                                                    
Directors of the Company, until the Effective Time, such Board of Directors
shall have at least three directors who are directors on the date of this
Agreement and who are not officers of the Company (the "Independent Directors");
                                                        ---------------------   
and provided, further that, in such event, if the number of Independent
    --------  -------                                                  
Directors shall be reduced below three for any reason whatsoever, the remaining
Independent Directors shall, to the fullest extent permitted by law, designate a
person to fill such vacancy who shall be deemed to be an Independent Director
for purposes of this Agreement or, if no Independent Directors then remain, the
other directors shall designate three persons to fill such vacancies who shall
not be officers or affiliates of the Company or any of its Subsidiaries, or
officers or affiliates of Parent or any of its Subsidiaries, and such persons
shall be deemed to be Independent Directors for purposes of this Agreement.
Following the election or appointment of Sub's designees pursuant to this
Section 7.10 and prior to the Effective Time, any amendment, or waiver of any
- ------------                                                                 
term or condition, of this Agreement or the Certificate of Incorporation or By-
Laws of the Company, any termination of this Agreement by the Company, any
extension by the Company of the time for the performance of any of the
obligations or other acts of Sub or waiver or assertion of any of the Company's
rights hereunder, and any other consent or action by the Board of Directors with
respect to this Agreement, will require the concurrence of a majority of the
Independent Directors and no

                                      -42-
<PAGE>
 
other action by the Company, including any action by any other director of the
Company, shall be required for purposes of this Agreement.  To the fullest
extent permitted by applicable law, the Company shall take all actions requested
by Parent which are reasonably necessary to effect the election of any such
designee, including mailing to its stockholders the Information Statement
containing the information required by Section 14(f) of the Exchange Act and
Rule 14f-1 promulgated thereunder, and the Company agrees to make such mailing
with the mailing of the Schedule 14D-9 (provided that Sub shall have provided to
                                        --------                                
the Company on a timely basis all information required to be included in the
Information Statement with respect to Sub's designees). Parent and Sub will be
solely responsible for any information with respect to either of them and their
nominees, officers, directors and affiliates required by Section 14(f) of the
Exchange Act and Rule 14f-1 promulgated thereunder.  In connection with the
foregoing, the Company will promptly, at the option of Parent, to the fullest
extent permitted by law, either increase the size of the Company's Board of
Directors and/or obtain the resignation of such number of its current directors
as is necessary to enable Sub's designees to be elected or appointed to the
Company's Board of Directors as provided above.

          SECTION 7.11  Reasonable Best Efforts.  Subject to fiduciary
                        -----------------------                       
responsibilities, each of the Company, Parent and Sub agrees to use its
reasonable best efforts to cause the purchase of Shares pursuant to the Offer
and the consummation of the Merger to occur as soon as practicable.  Without
limiting the foregoing, (a) each of the Company, Parent and Sub agree to use its
reasonable best efforts to take, or cause to be taken, all actions necessary to
comply promptly with all legal requirements that may be imposed on itself with
respect to the Offer and the Merger (which actions shall include furnishing all
information required under the HSR Act and in connection with approvals of or
filings with any other Governmental Entity) and shall promptly cooperate with
and furnish information to each other in connection with any such requirements
imposed upon any of them or any of their Subsidiaries in connection with the
Offer and the Merger and (b) each of the Company, Parent and Sub shall, and
shall cause its Subsidiaries to, use its reasonable best efforts to obtain (and
shall cooperate with each other in obtaining) any consent, authorization, order
or approval of, or any exemption by, any Governmental Entity or other public or
private third party required to be obtained or made by Parent, Sub, the Company
or any of their Subsidiaries in connection with the Offer and the Merger or the
taking of any action contemplated thereby or by this Agreement.  Notwithstanding
anything to the contrary contained in this Agreement, in connection with any
filing or submission required or action to be taken by Parent, the Company or
any of its respective Subsidiaries to consummate the Offer,

                                      -43-
<PAGE>
 
the Merger or the other transactions contemplated in this Agreement, the Company
shall not, without Parent's prior written consent, commit to any divestiture of
assets or businesses of the Company and its Subsidiaries if such divested assets
and/or businesses are material to the assets or profitability of the Company and
its Subsidiaries taken as a whole; and neither Parent nor any of its
Subsidiaries shall be required to divest or hold separate or otherwise take or
commit to take any action that limits its freedom of action with respect to, or
its ability to retain, the Company or any of the businesses, product lines or
assets of Parent or any of its Subsidiaries or that would have a Material
Adverse Effect on Parent.

          SECTION 7.12  Certain Litigation.  The Company agrees that it shall
                        ------------------                                   
not settle any litigation commenced after the date hereof against the Company or
any of its directors by any stockholder of the Company relating to the Offer,
the Merger or this Agreement without the prior written consent of Parent, which
consent shall not be unreasonably withheld.

          SECTION 7.13  Employee Benefits.  (a)  During the period from the
                        -----------------                                  
Effective Time until December 31, 1998, Parent shall maintain or cause to be
maintained wages, compensation levels, employee pension and welfare plans for
the benefit of employees and former employees of the Company or its Subsidiaries
which, in the aggregate, are not less favorable than those wages, compensation
levels and other benefits under the Benefit Plans that are in effect as of the
date hereof; provided, however, that Parent shall not have any obligation to
             --------  -------                                              
provide benefits based on equity securities or any equivalent thereof.  For all
purposes of eligibility to participate in and vesting in benefits provided under
employee benefits plans maintained by Parent and its Subsidiaries (but not for
purposes of determining benefits (or accruals thereof) under such plans) which
employees and former employees of the Company become eligible to participate in
after the Effective Time, all persons previously employed by the Company and its
Subsidiaries and then employed by Parent or its Subsidiaries shall be credited
with their years of service with the Company and its Subsidiaries and years of
service with prior employers to the extent service with prior employers is taken
into account under the Benefit Plans.

          (b)  The foregoing shall not constitute any commitment, contract,
understanding or guarantee (express or implied) on the part of the Parent or Sub
of a post-Effective Time employment relationship of any term of duration or on
any terms other than those that the Parent or Sub may establish.  Employment of
any of the employees by Parent will be "at will" and may be terminated by Parent
or Sub at any time for any reason (subject to any legally binding agreement
other than this Agreement, or any

                                      -44-
<PAGE>
 
applicable laws or collective bargaining agreement, or any other arrangement or
commitment).  Except as otherwise provided in Sections 7.13 through 7.17,
                                              -------------         ---- 
nothing in this Agreement shall be interpreted as limiting the power of the
Surviving Corporation to amend or terminate any particular Benefit Plan or any
other employee benefit plan, program, agreement or policy or as requiring the
Surviving Corporation or Parent to offer to continue (other than as required by
its terms) any written employment contract.

          SECTION 7.14  Severance Policy and Other Agreements. (a)  With respect
                        -------------------------------------                   
to any officer or employee who is covered by a severance policy or plan separate
from the standard severance policy for the Company's employees (which separate
severance policy or plan is described in item 7.14 of the Company Letter),
Parent shall maintain (or shall cause to be maintained) such separate policy or
plan as in effect as of the date hereof, and, as to all other officers and
employees, Parent shall maintain (or shall cause to be maintained) the Company's
standard severance policy as in effect as of the date hereof for a period of at
least 12 months from the Effective Time.

          (b) Parent shall honor or cause to be honored all severance agreements
and employment agreements with the Company's directors, officers and employees
to the extent disclosed in item 7.14 of the Company Letter (it being understood
that nothing herein shall be deemed to mean that the Company shall not be
required to honor its obligations under any severance agreement or employment
agreement to which it is a party).

          SECTION 7.15  1997 Bonus.  Parent will, or will cause the Surviving
                        ----------                                           
Corporation to, maintain the Company's bonus plans (as in effect on or before
March 1, 1997) through the end of the 1997 fiscal year, with bonuses to be paid
to the employee participating thereunder at the greater of (i) the target level,
if applicable, (ii) the prior year's bonus, or (iii) such bonus as the employee
would have earned if the transaction contemplated by this Agreement had not
occurred, in all events on a basis consistent with past practices.

          SECTION 7.16  Credit for Deductibles.  Parent will, or will cause the
                        ----------------------                                 
Surviving Corporation to, (i) waive all limitations as to preexisting
conditions, exclusions and waiting periods with respect to participation and
coverage requirements applicable to the employees of the Company under any
welfare plan that such employees may be eligible to participate in after the
Effective Time, other than limitations or waiting periods that are already in
effect with respect to such employees and that have not been satisfied as of the
Effective Time under any welfare plan maintained for the Company's employees
immediately

                                      -45-
<PAGE>
 
prior to the Effective Time, and (ii) provide each employee of the Company with
credit for any co-payments and deductibles paid prior to the Effective Time in
satisfying any applicable deductible or out-of-pocket requirements under any
welfare plans that such employees are eligible to participate in after the
Effective Time.

          SECTION 7.17  401(k)/Profit Sharing Contributions for 1997.  Parent
                        --------------------------------------------         
will, or will cause the Surviving Corporation to, prior to the end of the third
month following the end of the current fiscal year, make retirement
contributions to the Company's 401(k) plan on behalf of each eligible Company
employee who was employed on the last day of the current fiscal year of 4
percent of such employee's 1997 base salary and bonus up to $6,400 for each
Employee; provided, however, that for any amounts to which an employee would be
          --------  -------                                                    
entitled in excess of $6,400 for those employees whose base salary and bonuses
are in excess of $160,000, such excess amounts shall be paid to each such
employee on a basis consistent with past practice.  Notwithstanding the
foregoing, in the case of a Company employee who is terminated prior to December
31, 1997, the retirement contribution described in the previous sentence
(including any payment for any contribution in excess of $6,400) shall be made
not later than the date of the employee's termination.

construed in accordance with, the laws of the State of Delaware, regardless of
the laws that might otherwise govern under applicable principles of conflicts of
laws thereof.

          SECTION 10.7  Assignment.  Neither this Agreement nor any of the
                        ----------                                        
rights, interests or obligations hereunder shall be assigned by any of the
parties hereto without the prior written consent of the other parties, except
that Sub may assign, in its sole discretion, any of or all its rights, interests
and obligations under this Agreement to Parent or to any direct or indirect
wholly owned Subsidiary of Parent, but no such assignment shall relieve Sub of
any of its obligations hereunder. Subject to the preceding sentence, this
Agreement shall be binding upon, inure to the benefit of, and be enforceable by,
the parties and their respective successors and assigns.

          SECTION 10.8  Severability.  If any term or other provision of this
                        ------------                                         
Agreement is invalid, illegal or incapable of being enforced by any rule of law,
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic and legal
substance of the transactions contemplated hereby are not affected in any manner
materially adverse to any party.  Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties as closely as possible in a mutually acceptable manner in
order that the transactions contemplated by this Agreement may be consummated as
originally contemplated to the fullest extent possible.

          SECTION 10.9  Enforcement of This Agreement.  The parties hereto agree
                        -----------------------------                           
that irreparable damage would occur in the event that any of the provisions of
this Agreement were not performed in accordance with their specific terms or
were otherwise breached.  It is accordingly agreed that the parties shall be
entitled to an injunction or injunctions to prevent breaches of this Agreement
and to enforce specifically the terms and provisions hereof in any court of the
United States or any state having jurisdiction, such remedy being in addition to
any other remedy to which any party is entitled at law or in equity.

          SECTION 10.10  Obligations of Subsidiaries.  Whenever this Agreement
                         ---------------------------                          
requires any Subsidiary of Parent (including Sub) or of the Company to take any
action, such requirement shall be deemed to include an undertaking on the part
of Parent or the Company, as the case may be, to cause such Subsidiary to take
such action.

require, or be construed to require, the Company to take or omit any action,
which action or omission would constitute a breach of, or a default under, any
of the Asbestos Agreements, and any action or omission required to avoid a
breach of, or default under, any of the Asbestos Agreements shall not be deemed
a willful or intentional breach hereof.  Both parties recognize the Company's
obligations on the Interim Committee pursuant to Article 7 of the Global
Settlement Agreement and subsequent court orders to resolve Interim Claims and
to resolve Unsettled Present Claims and Presently Settled Claims (as defined in
the Asbestos Agreements) in accordance with applicable law.

                   OWENS CORNING AND FIBREBOARD CORPORATION
                           ANNOUNCE MERGER AGREEMENT

       OWENS CORNING TO ACQUIRE FIBREBOARD SHARES FOR $55.00 PER SHARE

TOLEDO, OHIO, AND DALLAS, TEXAS; MAY 28, 1997--Owens Corning (NYSE/TSE: OWC) and
Fibreboard Corporation (AMEX: FBD) today announced that they have entered into a
definitive merger agreement providing for Owens Corning to acquire all of the
outstanding shares of Fibreboard Corporation for $55.00 per share.

Under terms of the merger agreement, approved by the Boards of Directors of both
companies, a wholly owned subsidiary of Owens Corning will launch a cash tender 
offer for all of the issued and outstanding shares of Fibreboard common stock at
$55.00 per share, net to the seller. The tender offer will be subject to
customary conditions and is expected to commence no later than Tuesday, June 3,
1997.

Following the tender offer, and assuming the purchase by the Owens Corning 
subsidiary of a majority of the fully diluted outstanding Fibreboard shares 
pursuant to the tender offer, the remaining outstanding Fibreboard shares would 
be converted in the merger into $55.00 per share, in cash. As a result of the 
merger, Fibreboard will become a wholly owned subsidiary of Owens Corning.

The merger, Owens Corning's sixteenth acquisition during the past three years
and the largest to date, will substantially strengthen the company's offering in
building materials systems and provide Fibreboard the resources for continued
growth. Assuming expected synergies, the merger is expected to be accretive to
Owens Corning in 1997 and on an ongoing basis, excluding one-time, non-recurring
fees. The companies expect the transaction to close early in the third quarter
of 1997.

Owens Corning is a world leader in high performance glass fiber composites and 
building materials with sales in 1996 of $3.8 billion. Fibreboard is a leading 
producer of vinyl siding and other residential and industrial building 
materials. Sales in 1996 were $469 million. On a pro-forma basis--assuming 
Fibreboard's 1997 acquisitions had been completed on January 1, 1997--the 
company's sales this year would be expected to be close to $800 million.

"Merging Fibreboard's businesses with Owens Corning will substantially 
strengthen our offering of building materials systems and make us a major 
producer and marketer of vinyl siding, one of the fastest growing products in
the building materials market," said Glen H. Hiner, Owens Corning chairman and
chief executive officer.

"During the last three years Fibreboard has become one of the top producers of 
vinyl siding and accessories in North America," said Hiner. "The company is 
among the industry's low-cost producers and it has an extensive network of 
distribution centers for both vinyl siding and windows. These products will
become an integral part of our low-maintenance exterior system for the home."

Hiner said Fibreboard's other products--manufactured stone and industrial 
insulation products--also complement the company's portfolio of building 
materials.

John D. Roach, Fibreboard's chairman and CEO, said, "In the six years I have 
served as CEO of Fibreboard, my commitment has consistently been to strengthen 
the underlying business units, resolve the company's asbestos situation, 
develop a growth strategy and provide superior shareholder value. As a result,
Fibreboard has become one of the most exciting, fastest growing entities in the
building products sector.

"This merger catapults the existing growth platforms to a new, higher level of 
performance potential," Roach said. "The transaction brings immediate, 
excellent cash value to our shareholders and also benefits the constituent 
business units of Fibreboard. Our shareholders should be pleased as should 
Owens Corning. They are acquiring an outstanding company."

According to David Devonshire, Owens Corning's senior vice president and chief
financial officer, the transaction will be financed using a long-term bank
credit facility underwritten by a major financial institution. Devonshire also
indicated that the company remains committed to maintaining its investment grade
credit ratings and intends to implement capital structure modifications to
achieve that objective.

Owens Corning has been acquiring businesses and assets in recent years as part 
of the company's growth agenda. Acquisitions during the past three years 
accounted for $450 million of the company's sales in 1996.

Last September, Owens Corning introduced a new strategic thrust for the company 
called System Thinking/tm/. The first implementation of the new initiative,
System Thinking for the Home/tm/, responds to the fact that a majority of
consumers want integrated systems that address whole-project needs. The merger
with Fibreboard will substantially strengthen the ability to offer exterior
systems for the home.

Headquartered in Dallas, Texas, Fibreboard is currently one of the five largest 
producers of vinyl siding and accessories with plants in Georgia, Missouri and 
North Carolina in the U.S., and British Columbia and Ontario in Canada. 
Marketing products under the brand names Norandex and Vytec, the business also 
operates more than 130 company-owned distribution centers in 32 states. The 
company employs 3,400 people and operates a total of 21 manufacturing plants 
in the U.S. and Canada.

Fibreboard's Stone Products business is the pioneer and leading producer of 
manufactured stone, which it sells under the Cultured Stone/R/ brand.

Fibreboard's Pabco business produces calcium silicate insulation for industrial
pipe applications. The business is also a market leader in metal jacketing for 
pipe insulation and a specialty producer of fire safety products.

Earlier this month, Fibreboard completed the acquisition of Fabwel, Inc., a 
privately held, major producer and supplier of customized exterior components, 
including vinyl siding, for the manufactured housing, recreational vehicle and 
transportation industries.

Headquartered in Toledo, Ohio, Owens Corning employs 19,000 people in more than
30 countries.
