BIRD
CORPORATION                                                         [    , 1998]
 
To Our Stockholders:
 
  You are cordially invited to attend a special meeting (the "Special
Meeting") of the stockholders of Bird Corporation (the "Company"), to be held
on [       , 1998] at [   ]., local time, at             .
 
  At the Special Meeting, those of you who are holders of the Company's common
stock, par value $1 per share (the "Common Shares"), or the Company's $1.85
Cumulative Convertible Preference Stock, par value $1 per share ("Preference
Shares", and together with the Common Shares, the "Shares"), at the close of
business on        , 1998 will be entitled to consider and vote upon a
proposal to approve and adopt an Agreement and Plan of Merger, dated as of
January 12, 1998 (the "Merger Agreement"), among the Company, CertainTeed
Corporation, a Delaware corporation ("CertainTeed"), and BI Expansion II
Corp., a Massachusetts corporation and a wholly owned subsidiary of
CertainTeed ("Acquisition Sub"), pursuant to which Acquisition Sub will be
merged with and into the Company (the "Merger"), with the Company surviving
the Merger as a subsidiary of CertainTeed. In the Merger, each Share
outstanding on the effective date of the Merger (the "Effective Date") (other
than Shares held by stockholders who perfect their appraisal rights under
Massachusetts law, Shares held in the Company's treasury, and Shares held
directly by Acquisition Sub or CertainTeed) will be converted into the right
to receive $5.50 per share (in the case of Common Shares) and $20 per share,
which amount will not be adjusted for any dividends accrued and unpaid through
the Effective Date (in the case of Preference Shares), in each case in cash,
without interest. All outstanding shares of the Company's 5% Cumulative
Preferred Stock, par value $100 per share (the "5% Stock"), will remain issued
and outstanding after the Merger and are expected to be called for redemption
and retirement as soon as practicable following the Merger at a price equal to
$110 per share, plus all accrued and unpaid dividends through the date of
redemption and retirement. Details of the Merger and other important
information are set forth in the enclosed Information Statement, which you are
urged to read carefully.
 
  As previously communicated in the Tender Offer Statement on Schedule 14D-9
mailed to stockholders in January of this year, your Board of Directors
believes that the Merger is in the best interests of the Company and its
stockholders. In arriving at its decision to recommend the Merger, the Board
of Directors carefully reviewed and considered the terms and conditions of the
Merger Agreement and the factors described in the enclosed Information
Statement.
 
  The Merger is the second step in a two-part transaction, the purpose of
which is the acquisition of the Company by CertainTeed. On January 16, 1998,
Acquisition Sub commenced a tender offer (the "Offer") to purchase all
outstanding Common Shares and Preference Shares at a price of $5.50 per Common
Share and $20, without any adjustment for dividends accrued and unpaid through
the expiration date of the Offer, per Preference Share. In the Offer, which
expired at midnight, February 13, 1998 (the "Expiration Date"), Acquisition
Sub acquired approximately 95% of the outstanding Common Shares and
approximately 95% of the outstanding Preference Shares.
 
  CertainTeed and Acquisition Sub agreed in the Merger Agreement to vote all
Shares acquired in the Offer in favor of the Merger. Approval of the Merger
Agreement requires the affirmative vote of the holders of at least 66 2/3% of
the issued and outstanding Common Shares and 66 2/3% of the issued and
outstanding Preference Shares. Accordingly, Acquisition Sub has sufficient
voting power to approve the Merger Agreement without the vote of any other
stockholder of the Company.

 
  Holders of 5% Stock are receiving notice of, and may attend but not vote at,
the Special Meeting.
 
  WE ARE NOT ASKING YOU FOR A PROXY AND YOU ARE REQUESTED NOT TO SEND US A
PROXY.
 
                                          Sincerely,

  Notice is hereby given that a special meeting (the "Special Meeting") of
stockholders of Bird Corporation (the "Company") will be held on       , 1998
at [   ] a.m., local time, at           to consider and act upon the
following:
 
  1. The approval of an Agreement and Plan of Merger, dated as of January 12,
1998 (the "Merger Agreement"), among the Company, CertainTeed Corporation, a
Delaware corporation ("CertainTeed"), and BI Expansion II Corp., a
Massachusetts corporation and a wholly owned subsidiary of CertainTeed
("Acquisition Sub"), pursuant to which Acquisition Sub will be merged with and

stock, par value $1 per share ("Common Shares"), outstanding on the effective
date of the Merger (the "Effective Date") and each share of the Company's
$1.85 Cumulative Convertible Preference Stock, par value $1 per share
("Preference Shares", and together with Common Shares, the "Shares"),
outstanding on the Effective Date other than Shares held by stockholders who

Company's treasury, and Shares held by Acquisition Sub or CertainTeed) will be
converted into the right to receive $5.50 per share (in the case of Common
Shares) and $20 per share, which amount will not be adjusted for any dividends
accrued and unpaid through the Effective Date (in the case of Preference
Shares), in each case in cash, without interest. All outstanding shares of the

Stock"), will remain issued and outstanding after the Merger and are expected
to be called for redemption and retirement as soon as practicable following
the Merger at a price equal to $110 per share, plus all accrued and unpaid
dividends through the date of redemption and retirement. Details of the Merger
and other important information are set forth in the enclosed Information
Statement, which you are urged to read carefully.
 
  2. The transaction of such other business as may properly come before the
Special Meeting and any adjournment thereof.
 
  Reference is hereby made to the accompanying Information Statement for more
complete information concerning the matters to be acted upon at the Special
Meeting.
 
  Only holders of record of Common Shares and/or Preference Shares (except as
indicated below) at the close of business on [      , 1998] (the "Record
Date") are entitled to vote at the Special Meeting on the approval and
adoption of the Merger Agreement, including the consummation of the
transactions contemplated thereby. Holders of record of 5% Stock on the Record
Date are entitled to notice of, but not to vote at, the Special Meeting.
 
  The Merger is the second step in a two-part transaction, the purpose of
which is the acquisition of the Company by CertainTeed. On January 16, 1998,
Acquisition Sub commenced a tender offer (the "Offer") to purchase all
outstanding Common Shares and Preference Shares at a price of $5.50 per Common
Share and $20, without any adjustment for any dividends accrued and unpaid
through the expiration date of the Offer, per Preference Share. In the Offer,
which expired at midnight, February 13, 1998 (the "Expiration Date"),
Acquisition Sub acquired approximately 95% of the outstanding Common Shares
and approximately 95% of the outstanding Preference Shares.
 

 
  CertainTeed and Acquisition Sub agreed in the Merger Agreement to vote all
Shares acquired in the Offer in favor of the Merger. Approval of the Merger
Agreement requires the affirmative vote of the holders of at least 66 2/3% of
the issued and outstanding Common Shares and 66 2/3% of the issued and
outstanding Preference Shares. Accordingly, Acquisition Sub has sufficient
voting power to effect the Merger without the vote of any other stockholder of
the Company.
 
  Pursuant to Section 85 of the Massachusetts Business Corporation Law (the
"MBCL"), Chapter 156B of the Massachusetts General Laws, if the Merger
Agreement is approved by the holders of Common Shares and by the holders of
Preference Shares at the Special Meeting and the Merger is effected by the
Company, any stockholder (i) who files with the Company, before the taking of
the vote on the approval of the Merger Agreement, written objection to the
Merger stating that such stockholder intends to demand payment for such
stockholder's shares if the Merger is consummated, and (ii) in the case of
holders of Common Shares and holders of Preference Shares, whose shares are
not voted in favor of the Merger Agreement (including any holder of Common
Shares or Preference Shares who abstains, which abstention will be treated as
a "no" vote for purposes of determining whether the Merger Agreement has been
adopted or approved), may have the right to demand in writing from the
Company, within 20 days after the date of mailing to such stockholder of
notice in writing that the Merger has become effective, payment for such
stockholder's shares and an appraisal of the value thereof. The Company and
any such stockholder shall in such cases have the rights and duties and shall
follow the procedures set forth in Sections 88 to 98, inclusive, of the MBCL.
 
  WE ARE NOT ASKING YOU FOR A PROXY AND YOU ARE REQUESTED NOT TO SEND US A
PROXY.

the Merger (the "Effective Date") (other than Shares held by stockholders who
perfect their appraisal rights under Massachusetts law, Shares held in the
Company's treasury, and Shares held by Acquisition Sub or CertainTeed) will be
converted into the right to receive (in the case of Common Shares) $5.50 per
Common Share and (in the case of Preference Shares) $20, which amount will not

                              be treated as "no" votes for purposes of

Background and Reasons for
 the Merger.................
                              The Offer and the Merger represent the
                              culmination of numerous steps undertaken by the
                              Company over the past several years in an effort
                              to stem continuing losses, to reduce debt and to
                              find a strategic partner to invest in the
                              operations of the Company or a buyer to purchase
                              all or a substantial part of the Company. See
                              "THE MERGER--Background and Reasons for the
                              Merger."
 
Board of Directors Approval
 of the Merger Agreement....
                              The Board has determined that the terms of the
                              Merger are fair to and in the best interests of
                              the Company and its stockholders and has
                              unanimously approved the Merger Agreement and the
                              consummation of the transactions contemplated
                              thereby. The Board's decision to enter into the
                              Merger Agreement was based upon its evaluation of
                              a number of factors discussed in detail below,
                              including the opinion of the Company's financial
                              advisor. See "THE MERGER--Background and Reasons
                              for the Merger," "--Reasons for the Board's
                              Approval of the Merger Agreement" and "--Opinion
                              of Financial Advisor."
 
Opinion of Financial          Lehman Brothers has rendered a written opinion
 Advisor....................  dated January 12, 1998 to the Board to the effect
                              that, in its opinion, subject to the matters set
                              forth in its opinion, the consideration to be
                              received by the stockholders pursuant to the
                              Merger is fair to such stockholders from a
                              financial point of view. See "THE MERGER--Opinion
                              of Financial Advisor." A copy of such opinion,
                              which sets forth the assumptions made, the
                              matters considered and the limits of Lehman
                              Brothers review, is attached to this Information
                              Statement as Annex III and should be read in its
                              entirety.
 
Interests of Certain
 Persons in the Merger......
                              As a result of the "change in control" which
                              occurred upon the completion of the Offer,
                              Richard C. Maloof, the Company's President and
                              Chief Operating Officer, received a payment of
                              $720,000 under his employment agreement with the
                              Company and a payment of $135,000 under the
                              Company's 1998 Management Incentive Compensation
                              Program (the "1998 MICP") and Frank S. Anthony,
                              the Company's Vice President and General Counsel,
                              received a payment of $50,000 under the 1998
                              MICP. The Merger Agreement provides, subject to
                              the terms thereof, for the survival of certain
                              indemnification rights of the directors and
                              officers of the Company for a period of five
                              years after the Effective Date and, subject to
                              the terms thereof, obligates CertainTeed to use
                              all reasonable efforts to maintain directors' and
                              officers' liability insurance covering the
                              directors and officers of the Company currently
                              covered under the Company's policy for a period
                              of two
 
                                       2

 
                              years after the Effective Date. CertainTeed has
                              had preliminary discussions with Messrs. Maloof
                              and Anthony regarding continued employment with
                              the Surviving Company, but these discussions have
                              not yet resulted in any written commitments by
                              any of the parties. See "THE MERGER--Interests of
                              Certain Persons in the Merger" and "THE MERGER
                              AGREEMENT--Indemnification and Insurance."
 
Certain Regulatory Matters..  The Offer was subject to the requirements of the
                              Hart-Scott-Rodino Antitrust Improvements Act of
                              1976, as amended, and the regulations thereunder
                              (the "HSR Act"), which provides that certain
                              transactions may not be consummated until
                              required information and material have been
                              furnished to the Antitrust Division of the
                              Department of Justice (the "Antitrust Division")
                              and the Federal Trade Commission (the "FTC") and

                              not believe that any other material regulatory
                              approvals are required for consummation of the
                              Merger. See "THE MERGER--Certain Regulatory

                                  THE MERGER
 
THE COMPANY
 
  As a result of the various sales of its assets and businesses within the
last five years, including its vinyl building products business, window
fabrication business and San Leon hydrocarbon waste recycling center, the
Company's current manufacturing operation consists of one primary business
unit--roofing manufacturing, sales, and marketing. Products currently
manufactured at the Company's roofing facility include asphalt shingles and
roll roofing for commercial and residential use. These products are marketed
through independent wholesalers, including wholesalers whose primary customers
are roofing contractors.
 
  The principal executive office of the Company are located at 1077 Pleasant
Street, Norwood, Massachusetts 02062 and its telephone number is (781) 551-
0656.
 
CERTAINTEED AND ACQUISITION SUB
 
  Acquisition Sub, a Massachusetts corporation and a wholly owned subsidiary
of CertainTeed, was organized to acquire the Company and has not conducted any
unrelated activities since its organization. All outstanding shares of capital
stock of Acquisition Sub are owned by CertainTeed. The principal office of
Acquisition Sub is located at the principal office of CertainTeed.
 
  The principal business of CertainTeed is the manufacture of building
materials (roofing, vinyl siding, vinyl windows, ventilation products, vinyl
fence and railing, and piping products) and fiberglass products (insulation
and reinforcements). The principal office of CertainTeed, a Delaware
corporation and an indirect wholly owned subsidiary of Compagnie de Saint-
Gobain, a French corporation ("Saint-Gobain"), is located at 750 East
Swedesford Road, Valley Forge, Pennsylvania 19842 and its telephone number is
(610) 341-7000.
 
BACKGROUND AND REASONS FOR THE MERGER
 
  The Offer and the Merger represent the culmination of numerous steps
undertaken by the Company over the past several years in an effort to stem
continuing losses, to reduce debt, and to find a strategic partner to invest
in the operations of the Company or a buyer to purchase all or a substantial
part of the Company.
 
  In 1993, the Company experienced severe financial setbacks which caused it
to default in the performance of certain operating and other covenants
contained in its agreement with its lending banks and required the Company to
classify the related debt as current on its September 30, 1993 balance sheet.
In response to these problems, during 1993, the Company embarked on a program
which included refocusing the Company on its core business (i.e., its building
materials manufacturing businesses), the elimination of unrelated and
nonessential functions, the imposition of strict cost control measures and the
restructuring of its bank lines of credit.
 
  In furtherance of this program, the Company, in the fourth quarter of 1993,
began to eliminate its non-core businesses by (i) withdrawing from its on-site
environmental remediation business pursuant to a series of minor asset sales
and winding down and closing the balance of such business (a process completed
in August 1994) and (ii) seeking a buyer for all of its building materials
distribution business. This effort resulted in the sale of the Company's
distribution business to two subsidiaries of Cameron Ashley, Inc. for an
aggregate purchase price of approximately $28,000,000 in two transactions
which closed in August and November of 1994, respectively.
 
  In addition and as part of its restructuring program, the Company
renegotiated its bank lines of credit, entering into further amendments to its
credit facilities in March of 1994. In its effort to focus on its core
business, the Company built a $5.5 million asphalt oxidizing plant at its
Norwood, Massachusetts roofing plant. The oxidizing plant is designed to (i)
reduce the Company's operating costs associated with obtaining processed
asphalt from suppliers in other states; and (ii) provide the Company with a
convenient and reliable source of processed asphalt for use in the Company's
roofing manufacturing operations.
 
                                      10

 
  Despite these restructuring efforts, the deterioration of the Company's
financial condition continued. Consequently, in April of 1994, the Company
expanded the scope of its restructuring efforts by commencing an active search
to find a buyer or merger partner for the Company as a whole. The Company
engaged a financial advisor to assist in these efforts. In light of the
intensive nature of these efforts, in May of 1994 the Board formed the
Strategic Planning Committee, a special committee of the Board, to supervise
the Company's efforts to attract a purchaser of the Company's stock or assets
and to make appropriate recommendations and reports to the full Board
regarding such process.
 
  As the Company's efforts progressed, the Company's management, the Board,
the Strategic Planning Committee, and the Company's financial and legal
advisors met together and individually on numerous occasions between May and
September 1994 to reevaluate the Company's alternatives, including the
possibility of a substantial downsizing of the Company through a sale of the
Company's vinyl business headquartered in Bardstown, Kentucky (the "Vinyl
Business") and the Company's interests in Kensington Partners ("Kensington")
(the Vinyl Business and the Company's interests in Kensington and such
entity's business operations, taken as a whole, are referred to herein as the
"Combined Vinyl Business"). The sale of the Combined Vinyl Business was
proposed to enable the Company to achieve a significant reduction in, or the
elimination of, the Company's debt.
 
  The Offer and Merger represent the culmination of a series of negotiations
between CertainTeed and the Company that began at the Company's initiation in
1994. During the spring and early summer of that year, management of the
Company and of CertainTeed undertook to negotiate a proposed merger at a cash
price of $13 per Common Share (plus a contingent purchase price of up to $1.25
per Common Share). That transaction would also have included the redemption of
the 5% Stock and the Preference Shares. In July of 1994, however, CertainTeed
informed the Company that because CertainTeed's only interest was in acquiring
the Company's roofing manufacturing business, CertainTeed was not prepared to
acquire the Company's assets and contingent liabilities unrelated to its core
roofing business. As a result, the Company and CertainTeed terminated their
negotiations. Shortly thereafter, CertainTeed indicated orally that it
remained interested in acquiring the Company's roofing plant or the entire
Company if all or a substantial portion of its non-roofing assets could be
divested prior to a CertainTeed acquisition of the Company. In September of
1994, the Company provided additional due diligence materials and suggested
continuing discussions.
 
  During the next several months, the Company received various expressions of
interest from potential purchasers to acquire the entire Company, the Combined
Vinyl Business, or the Company's roofing manufacturing business but received
only two formal offers, both of which were for the Vinyl Business. The Board
and the Strategic Planning Committee met on several occasions with senior
management and the Company's financial advisor and independent legal counsel
to discuss the Company's options in light of the offers presented. The Board
decided to pursue only the offer presented by Jannock, Inc., because the Board
believed that a financing contingency included in the other offer made it too
uncertain.
 
  After careful consideration of all available options, in March of 1995 the
Company sold (with prior stockholder approval) the Vinyl Business (the "Vinyl
Sale") to Jannock, Inc. ("Jannock") for $42.5 million plus the assumption by
Jannock of certain specified liabilities of the Vinyl Business. This
transaction also included a grant to Jannock of an option to purchase the
Company's interest in Kensington. In June 1995 Jannock exercised this option
and the Company paid approximately $1.4 million to divest Kensington.
 
  During the summer of 1995, the Company and CertainTeed renewed discussions,
including a meeting at CertainTeed's headquarters in Valley Forge,
Pennsylvania, at which the status of the Company's asset disposition and
contingent liability management program was discussed. The Company indicated
that all material non-roofing assets, other than its interest in a San Leon,
Texas hydrocarbon waste recycling center (the "San Leon Facility"), had been
divested and that an effort to sell the Company's interest in the San Leon
Facility was underway. During the fall of 1995, CertainTeed resumed its due
diligence investigation of the Company. Discussions between the parties
regarding issues raised during CertainTeed's ongoing due diligence effort
continued on a regular basis through February of 1996.
 
                                      11

 
  On September 12, 1995, the Company received a notice (the "Notice") from a
prospective purchaser, indicating that it intended to purchase at least 50% of
the Company's Common Stock in open market or privately negotiated
transactions. The purchases contemplated by the Notice required compliance
with the HSR Act pre-merger filing requirements, which requirements were
subsequently satisfied. On March 12, 1996, the Company received a letter from
the Federal Trade Commission stating that its review of the proposed
transaction was closed but reserving the right to take such further action as
the public interest may require. The Company did not receive any offer or
subsequent notices from the prospective purchaser, however.
 
  In November of 1995, the Company caused Bird Environmental Technologies,
Inc. ("BETI") to sell BETI's outstanding capital stock of Bird Environmental
Gulf Coast, Inc. ("BEGCI"), which owned the San Leon Facility, to GTS Duratek,
Inc. for a purchase price of $1.00. In addition, BETI (the 80% owner of BEGCI
and an indirect wholly owned subsidiary of the Company) agreed to pay the
purchaser the amount by which BEGCI's current liabilities exceeded its current
assets at August 31, 1995, which was approximately $1.3 million. The sale of
the San Leon Facility completed the Company's withdrawal from the
environmental remediation and recycling industry.
 
  During January 1996, another qualified prospective purchaser expressed an
interest in purchasing the Company. Pursuant to such expression of interest,
such party performed extensive due diligence of the Company and its assets and
liabilities but ultimately declined to make an offer due to the existence and
the threat of certain contingent liabilities relating to the Company's current
and prior roofing business.
 
  In late February and early March of 1996, representatives of CertainTeed
spoke by telephone with representatives of the Company on a number of
occasions regarding the possibility of CertainTeed making a proposal to
acquire the Company. On March 4, 1996, CertainTeed indicated that (i) it was
prepared to propose an acquisition price of $7.50 per Common Share, subject to
negotiation of definitive agreements and agreement upon a satisfactory
arrangement regarding alternative transaction fees and expenses; and (ii) as
in 1994, it was prepared to cash out the Preference Shares at their
liquidation value, plus all accrued and unpaid dividends, as well as to redeem
the 5% Stock in accordance with its terms. Detailed negotiations ensued
between the Company and CertainTeed, culminating in the execution of a merger
agreement (the "1996 Merger Agreement") on March 14, 1996.
 
  On April 3, 1996, CertainTeed indicated that it desired to acquire control
of the Company on the somewhat more accelerated timetable permitted by a cash
tender offer. The Board considered and approved CertainTeed's proposal on
April 5, 1996, and on April 12, 1996 a subsidiary of CertainTeed commenced a
cash tender offer (the "1996 Tender Offer") for all outstanding Common Shares
at a price of $7.50 per share and all outstanding Preference Shares at a price
of $20 per share, plus all accrued and unpaid dividends through the date of
the expiration of the 1996 Tender Offer (approximately $1.85 per share as of
April 1996).
 
  On May 2, 1996, CertainTeed informed the Company that CertainTeed had
concluded that certain conditions to the 1996 Tender Offer would not be
satisfied at the scheduled expiration of such offer, that CertainTeed would
not waive the conditions and that, accordingly, such offer would expire
without the CertainTeed subsidiary acquiring any Shares. On May 10, 1996, the
1996 Tender Offer expired pursuant to its terms without the CertainTeed
subsidiary acquiring any Shares. Thereafter, the 1996 Merger Agreement was
terminated.
 
  In August 1996, Joseph D. Vecchiolla, the Company's Chairman at the time,
and Mr. Anthony met in New York City with representatives of a major U.S.
roofing manufacturer to discuss a possible combination, but no proposal was
forthcoming.
 
  In December 1996, Messrs. Maloof and Anthony met in Norwood, Massachusetts
with a representative of a roofing manufacturer that had expressed an interest
in acquiring the Company. Extensive due diligence was performed, but in August
1997 the potential buyer stated over the telephone to Mr. Vecchiolla that it
would not make an offer because of its concerns with respect to possible
environmental liabilities and because the Company's earnings in 1997 had been
deteriorating.
 
                                      12

 
  On October 24, 1997, Messrs. Maloof, Anthony, and Vecchiolla met with a
roofing manufacturer at its headquarters. After subsequent discussions and a
due diligence review, an acquisition proposal was delivered to the Company in
December 1997. The Company decided not to pursue that proposal after reviewing
its terms and considering the December 1997 CertainTeed proposal, which
offered a higher purchase price.
 
  In November 1997, Mr. Maloof spoke by telephone to the president of yet
another roofing manufacturer to discuss a possible combination. This
manufacturer delivered to the Company an acquisition proposal. Messrs. Maloof
and Anthony met with this potential acquirer at its offices in December 1997,
which resulted in the issuance of an amended proposal. The Company decided not
to pursue the amended proposal after reviewing its terms and considering the
December 1997 CertainTeed proposal, which offered a higher purchase price.
 
  During 1997, other roofing manufacturers and non-manufacturers expressed an
interest in combining with the Company. Each was sent detailed financial and
operational information about the Company. None expressed any further interest
in a transaction with the Company.
 
  On December 11 and 12, 1997, Bradford C. Mattson, Executive Vice President,
Exterior Products Group, of CertainTeed, spoke by telephone with Mr. Maloof
regarding the possibility of a renewed interest by CertainTeed of making a
proposal to acquire the Company. During these conversations, Mr. Mattson was
informed that two other prospective purchasers were conducting investigations
of the Company and had or would likely submit acquisition proposals to the
Company. On December 14, 1997, Messrs. Mattson and Maloof discussed, among
other things, several environmental matters relating to the Company. On
December 15, 1997, John R. Mesher, Vice President and General Counsel of
CertainTeed, spoke by telephone with Mr. Anthony to discuss the timetable and
process for CertainTeed to explore acquiring the Company. Mr. Mesher was
advised that in order for CertainTeed to be involved in the process, a
meaningful, but non-binding, proposal would have to be submitted on or prior
to December 18, 1997. On the evening of December 15, 1997, representatives of
CertainTeed (Mr. Mattson, Mickey Trapnell, Vice President-Finance Controller,
Roofing Products Group, and Rudy T. Lee, Vice President-Sales, Roofing
Products Group) had a dinner meeting with Messrs. Maloof and Anthony. This
dinner meeting was followed the next day by a tour of the Company's facilities
and properties and a review of the Company's operations by Messrs. Mattson,
Trapnell and Lee, as well as James E. Hilyard, the President of CertainTeed's
Roofing Products Group. In addition, over the next several days, James J.
Smith, CertainTeed's Director of Environmental Affairs, discussed with Mr.
Maloof several environmental issues relating to the Company and its
operations.
 
  On December 18, 1997, CertainTeed submitted to the Company a non-binding
expression of interest confirming CertainTeed's interest in acquiring all the
equity of the Company for an aggregate purchase price of approximately $39.5
million. Between December 20, 1997 and December 22, 1997, Messrs. Maloof
and/or Anthony spoke by telephone with Mr. Mesher and/or George B. Amoss,
CertainTeed's Vice President-Finance, to discuss questions that the Company's
management and Board had with respect to CertainTeed's expression of interest.
 
  Detailed negotiations then ensued between the Company and CertainTeed,
culminating in agreement on the terms of the Merger Agreement, which included
an Offer price and Merger consideration of $5.50 per Common Share and $20 per
Preference Share, without any adjustment for any dividends accrued and unpaid
through the Expiration Date or the Effective Date. At a meeting on January 12,
1998, the Board of the Company unanimously determined that the Offer and the
Merger are fair to, and in the best interests of, the Company and the
Company's stockholders and approved the Merger Agreement and recommended that
the holders of Shares tender their Shares pursuant to the Offer and vote in
favor of approval and adoption of the Merger Agreement. The Merger Agreement
was executed and delivered by the parties on January 12, 1998. On that same
date, the Directors of the Company also executed the Stockholder Agreement.
The Company and CertainTeed issued a joint press release regarding the Offer
and Merger Agreement on January 13, 1998.
 
  On February 16, 1998, Acquisition Sub accepted for payment pursuant to the
Offer approximately 95% of the Common Shares and approximately 95% of the
Preference Shares.
 
                                      13

 
REASONS FOR THE BOARD'S APPROVAL OF THE MERGER AGREEMENT
 
  In reaching its conclusions described above, the Board considered, among
other things, the following factors:
 
    (1) The prospect of continuing to operate the Company's roofing plant at
  Norwood, Massachusetts as a single plant roofing operation and the Board's
  perception that current industry, economic and market conditions, and
  trends relative to the roofing industry are negative, as well as concerns
  about the impact of increased competition resulting from industry
  consolidation, and the Board's view of the Company's projected future value
  on a stand-alone basis compared to the consideration available in the Offer
  and the Merger. The Board took into account certain significant competitive
  advantages enjoyed by competitors of the Company's roofing manufacturing
  business, including, but not limited to, increased purchasing power for raw
  materials, geographical diversity resulting in lower vulnerability to
  seasonality due to weather, and stronger balance sheets which, among other
  things, provide them with opportunities for growth in a capital intensive
  industry, which opportunities are not available to the Company.
 
    (2) The fact that following its extensive but unsuccessful negotiations
  with certain interested parties in 1994, 1995, 1996, and 1997, it was
  reasonably unlikely that the Company would receive, in the foreseeable
  future, offers to engage in alternative transactions on terms more
  favorable to the Company and its stockholders than those offered by
  CertainTeed.
 
    (3) The proposed terms and structure of the Merger and the terms and
  conditions of the Merger Agreement and the Offer. In this regard, the Board
  specifically considered the ability of the Company to terminate the Merger
  Agreement prior to the completion of the Offer, notwithstanding the non-
  solicitation provisions contained therein, upon the occurrence or non-
  occurrence of certain events, and the limited application of the provisions
  contained in the Merger Agreement pertaining to the $1,500,000 Alternate
  Transaction Fee, as described more fully under "The Merger Agreement."
 
    (4) The effect of the Offer and the Merger on the stockholders of the
  Company, as well as on the Company's employees.
 
    (5) The written opinion dated January 12, 1998 (the "Opinion") delivered
  by Lehman Brothers to the Board that, subject to the matters set forth
  therein, from a financial point of view the consideration to be paid by
  CertainTeed pursuant to the Offer and the Merger is fair to the
  stockholders of the Company. A copy of the Opinion, which sets forth the
  assumptions made, matters considered and limits of the review by Lehman
  Brothers in rendering the Opinion, is attached as Annex III hereto.
  Stockholders are urged to read the Opinion in its entirety.
 
    (6) The experience, favorable reputation, and perceived motivation of
  CertainTeed and its executives and CertainTeed's financial condition and
  strength, which factors demonstrated CertainTeed's financial ability and
  underscored CertainTeed's earnest intent to consummate the Offer and the
  Merger.
 
  In light of the Board's uneasiness with operating a single plant roofing
business in an industry that has been consolidating with other participants
that are larger and financially stronger than the Company and the value
available in the Offer and the Merger, the Board determined that the Offer and
the Merger are in the best interest of the Company and its stockholders.
 
  The Board analyzed and considered all of the foregoing factors in comparing
its alternatives to the Offer and the Merger and in evaluating the merits of
the Offer and the Merger, including the opinion of Lehman Brothers.
 
  In view of the wide variety of factors considered in connection with its
evaluation of the Offer and the Merger, the Board did not find it practicable
to, and did not, quantify or otherwise attempt to assign relative weights to
the specific factors considered in reaching its respective determinations. For
purposes of the reviews described above, the Board adopted, as its own, the
analyses of Lehman Brothers.
 
 
                                      14

 
OPINION OF LEHMAN BROTHERS
 
  Lehman Brothers, as part of its services as financial advisor to the Company
in connection with the Offer and the Merger was asked to render an opinion to
the Board as to the fairness, from a financial point of view, to the Company's
stockholders of the consideration to be paid by CertainTeed in the Offer and
Merger.
 
  On January 12, 1998, Lehman Brothers delivered its oral opinion to the Board
(subsequently confirmed in writing as of such date) to the effect that as of
such date the consideration to be paid by CertainTeed in the Offer and Merger
is fair to such stockholders from a financial point of view.
 
  THE FULL TEXT OF THE OPINION IS ATTACHED AS ANNEX III TO THIS INFORMATION
STATEMENT AND IS INCORPORATED HEREIN BY REFERENCE. STOCKHOLDERS MAY READ THE
OPINION FOR A DISCUSSION OF ASSUMPTIONS MADE, MATTERS CONSIDERED AND
LIMITATIONS OF THE REVIEW UNDERTAKEN BY LEHMAN BROTHERS IN RENDERING THE
OPINION. THE SUMMARY OF THE OPINION SET FORTH IN THIS INFORMATION STATEMENT IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE OPINION.
 
  No limitations were imposed by the Company on the scope of Lehman Brothers'
investigation or the procedures to be followed by Lehman Brothers in rendering
the Opinion, except that Lehman Brothers was not authorized to solicit, and
did not solicit, any proposals from any third party with respect to a purchase
of all or a part of the Company's business. In arriving at the Opinion, Lehman
Brothers did not ascribe a specific value to the Company, but rather made its
determination as to the fairness, from a financial point of view, of the
consideration to be offered to the stockholders of the Company in the Offer
and Merger on the basis of the financial and comparative analyses described
below. Lehman Brothers' Opinion is for the use and benefit of the Board and
was rendered to the Board in connection with its consideration of the Offer
and Merger. Lehman Brothers' Opinion is not intended to be and does not
constitute a recommendation to any stockholder of the Company as to whether to
accept the consideration offered to such stockholders in connection with the
Offer and Merger. Lehman Brothers was not requested to opine as to, and the
Opinion does not address, (i) the Company's underlying business decision to
proceed with or effect the Offer and Merger; or (ii) the consideration to be
received by any class of stockholder of the Company.
 
  In arriving at its Opinion, Lehman Brothers reviewed and analyzed: (1) the
Merger Agreement and the specific terms of the Offer and Merger; (2) publicly
available information concerning the Company that Lehman Brothers believed to
be relevant to its analysis; (3) financial and operating information with
respect to the business, operations and prospects of the Company furnished to
Lehman Brothers by the Company (including without limitation the Company's
recent financial results in comparison to original budget); (4) a trading
history of the Company's capital stock from January 1995 to the present and a
comparison of that trading history with those of other companies that Lehman
Brothers deemed relevant; (5) a comparison of the historical financial results
and present financial condition of the Company with those of other companies
that Lehman Brothers deemed relevant; and (6) a comparison of the financial
terms of the Offer and Merger with the financial terms of certain other
transactions that Lehman Brothers deemed relevant. In addition, Lehman
Brothers had discussions with management of the Company concerning indications
of interest received from, and discussions with, potential strategic buyers of
the Company with respect to an acquisition of the Company. Lehman Brothers
also had discussions with the management of the Company concerning its
business, operations, assets, financial condition and prospects and the
current competitive environment in its industry, and undertook such other
studies, analyses and investigations as Lehman Brothers deemed appropriate.
 
  In arriving at the Opinion, Lehman Brothers has assumed and relied upon the
accuracy and completeness of the financial and other information used by it
without assuming any responsibility for independent verification of such
information and further relied upon the assurances of management of the
Company that they were not aware of any facts or circumstances that would make
such information inaccurate or misleading. With respect to the financial
projections of the Company, upon advice of the Company Lehman Brothers assumed
that such projections were reasonably prepared on a basis reflecting the best
currently available estimates and judgments
 
                                      15

 
of the management of the Company as to the future financial performance of the
Company and relied upon such projections in arriving at the Opinion. In
arriving at the Opinion, Lehman Brothers conducted only a limited physical
inspection of the properties and facilities of the Company and did not make or
obtain any evaluations or appraisals of the assets or liabilities of the
Company. In addition, the Company did not authorize Lehman Brothers to
solicit, and Lehman Brothers did not solicit, any proposals from any third
party with respect to the purchase of all or a part of the Company's business.
The Opinion necessarily was based upon market, economic and other conditions
as they existed on, and could be evaluated as of, the date of such opinion.
 
  In connection with the preparation and delivery of the Opinion to the Board,
Lehman Brothers performed certain financial and comparative analyses as
described below. The preparation of a fairness opinion involves various
determinations as to the most appropriate and relevant methods of financial
and comparative analysis and the application of those methods to the
particular circumstances, and therefore, such an opinion is not readily
susceptible to summary description. Furthermore, in arriving at the Opinion,
Lehman Brothers did not attribute any particular weight to any analysis or
factor considered by it, but rather made qualitative judgments as to the
significance and relevance of each analysis and factor. Accordingly, Lehman
Brothers believes that its analyses must be considered as a whole and that
considering any portion of such analyses and factors, without considering all
analyses and factors, could create a misleading or incomplete view of the
process underlying the Opinion. In its analyses, Lehman Brothers made numerous
assumptions with respect to industry performance, general business and
economic conditions and other matters, many of which are beyond the control of
the Company. Any estimates contained in these analyses are not necessarily
indicative of actual values or predictive of future results or values, which
may be significantly more or less favorable than as set forth herein. In
addition, analyses relating to the value of businesses do not purport to be
appraisals or to reflect the prices at which businesses actually may be sold.
 
  Discounted Cash Flow Analysis--Lehman Brothers prepared an after-tax cash
flow model that was based upon financial projections prepared by management of
the Company. Lehman Brothers used discount rates of 11% to 13% and a terminal
value based on: (1) the perpetuity value of after-tax unlevered free cash flow
assuming a growth rate of 2.0% to 4.0% annually; and (2) range of multiples of
8.0x to 10.0x the Company's projected fiscal 2002 estimated earnings before
interest, taxes, depreciation, amortization and non-recurring items
("EBITDA"). The discount rates were based on Lehman Brothers analysis of the
weighted average cost of capital for comparable companies selected by Lehman
Brothers.
 
  Comparable Transactions Analysis--Lehman Brothers reviewed certain publicly
available information on selected transactions which took place from 1993 to
1997 that Lehman Brothers deemed comparable. For each transaction, relevant
transaction multiples were analyzed including the total purchase price (equity
purchase price plus any assumed obligations) divided by (i) latest twelve
months ("LTM") revenues; (ii) LTM EBITDA; and (iii) LTM earnings before
interest and taxes ("EBIT"). The selected transactions provided a range of
valuation multltiples of 0.8x to 1.0x, 8.0x to 10.0x and 11.0x to 14.0x,
respectively.
 
  However, because the market conditions, rationale and circumstances
surrounding each of the transactions analyzed were specific to each
transaction and because of the inherent differences between the businesses,
operations, financial conditions and prospects of the Company and the acquired
businesses analyzed, Lehman Brothers believed that it was inappropriate to,
and therefore did not, rely solely on the quantitative results of the
analysis, and accordingly, also made qualitative judgments concerning
differences between the characteristics of these transactions and the Merger
that would affect the acquisition values of the Company and such acquired
companies.
 
  Comparable Company Trading Analysis--Lehman Brothers reviewed the public
stock market trading multiples for selected companies that Lehman Brothers
deemed comparable. Using publicly available information, Lehman Brothers
calculated and analyzed the enterprise value multiples of certain historical
financial criteria (such as revenues, EBITDA and EBIT). The enterprise value
of each company was obtained by adding its short and long-term debt to the sum
of the market value of its common equity, the value of its preferred
 
                                      16

 
stock (market value if publicly traded, liquidation value if not) and the book
value of any minority interest minus its cash and cash equivalents. The
appropriate LTM revenue, LTM EBIT and LTM EBITDA multiple ranges were
determined to be 0.9x to 1.1x, 9.0x to 10.0x and 7.0x to 8.0x, respectively.
 
  However, because of the inherent differences between the businesses,
operations, financial conditions and prospects of the Company and the
businesses, operations, financial conditions and prospects of the companies
included in the comparable company group, Lehman Brothers believed that it was
inappropriate to, and therefore did not, rely solely on the quantitative
results of the analysis, and accordingly, also made qualitative judgments
concerning differences between the financial and operating characteristics of
the Company and companies in the comparable company group that would affect
the public trading values of the Company and such comparable companies.
 
  Lehman Brothers is an internationally recognized investment banking firm
and, as part of its investment banking activities, is regularly engaged in,
among other things, the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings,
competitive bids, secondary distributions of listed and unlisted securities,
private placements, and valuations for corporate and other purposes. The Board
selected Lehman Brothers because of its expertise, reputation and familiarity
with the Company and because its investment banking professionals have
substantial experience in transactions comparable to the Offer and Merger.
 
  Lehman Brothers received a fee of $250,000 for the delivery of the Opinion.
In addition, the Company has agreed to reimburse Lehman Brothers for certain
expenses incurred in connection with its services as financial advisor and to
indemnify Lehman Brothers for certain liabilities that may arise out of the
rendering of its opinion.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
  Stockholders should be aware that the executive officers and directors of
the Company have interests in the Merger that are in addition to or different
from the interests of stockholders of the Company generally. These interests
are discussed below.
 
  Executive Severance Contract. Under the terms of a severance agreement
between the Company and Richard C. Maloof, the Company's President and Chief
Operating Officer, a "change in control" occurred upon Acquisition Sub's
acceptance for payment and payment for Shares in the Offer and Mr. Maloof
became entitled to a payment of $720,000, which was paid on February 20, 1998.
No further "change in control" will be deemed to have occurred upon the
consummation of the Merger.
 
  Incentive Compensation Program. As a result of the completion of the Offer,
Mr. Maloof was paid a bonus of $135,000 and Frank S. Anthony, the Company's
Vice President and General Counsel, was paid a bonus of $50,000 pursuant to
the Company's 1998 MICP. No additional payment will be due to Mr. Maloof or
Mr. Anthony pursuant to the 1998 MICP as a result of the consummation of the
Merger.
 
  Indemnification and Insurance. The Merger Agreement provides that
CertainTeed and Acquisition Sub have agreed that certain rights of
indemnification in existence as of the date of the Merger Agreement in favor
of the directors and officers of the Company and its subsidiaries (the
"Indemnified Parties") as currently provided in their respective certificates
or articles of incorporation or organization and the by-laws or any
agreements, contracts, or arrangements with the Company or any of its
subsidiaries in effect as of the date of the Merger Agreement shall survive
the Merger and shall continue in full force and effect for a period of five
years after the Effective Date provided that, in the event any claim or claims
are asserted or made within such five year period, all rights to
indemnification in respect of any such claim or claims shall continue until
the disposition of any and all such claims. In addition, the Merger Agreement
provides that, to the extent currently provided in the certificates or
articles of incorporation or organization and by-laws of the Company and its
subsidiaries and Massachusetts law, or agreements, contracts or arrangements
disclosed to CertainTeed with the Company or any of the subsidiaries, in the
event that any Indemnified Party becomes involved in any capacity in any
action,
 
                                      17

 
proceeding or investigation in connection with any matter, including the
transaction contemplated by the Merger Agreement, occurring prior to, and
including, the Effective Date, or otherwise relating to or arising out of such
matters, CertainTeed or the Surviving Company will periodically advance to
such Indemnified Party his or her legal and other expenses (including the
costs of any investigation and preparation incurred in connection therewith).
 
  In addition, the Merger Agreement provides that CertainTeed shall use all
reasonable efforts to maintain in effect, or cause the Surviving Company to
use all reasonable efforts to maintain in effect, for two years after the
Effective Date, directors' and officers' liability insurance ("D&O Insurance")
covering those persons covered by the Company's directors' and officers'
liability insurance on the date of the Merger Agreement or the Effective Date
and which is substantially equivalent in terms of coverage and amount as the
Company has in effect on the Effective date so long as such insurance is
available and the annual premium therefor would not be in excess of $166,000
(the "Maximum Premium"). If the existing D&O Insurance expires, is terminated
or canceled during such two-year period, CertainTeed shall use all reasonable
efforts to cause to be obtained as much D&O Insurance as can be obtained for
the remainder of such period for an annualized premium not in excess of the
Maximum Premium, on terms and conditions no less advantageous than the
existing D&O Insurance. See "THE MERGER AGREEMENT--Indemnification and
Insurance."
 
  The Merger Agreement further provides that (a) any Indemnified Party wishing
to claim indemnification pursuant to the Merger Agreement, upon learning of
any legal action, suit, investigation, inquiry or proceeding by any
governmental authority or other person, shall promptly notify CertainTeed and
the Surviving Company with respect thereto, but the failure to so notify shall
not relieve CertainTeed or the Surviving Company of any liability it may have
to such Indemnified Party under the Merger Agreement except to the extent that
CertainTeed and the Surviving Company are materially prejudiced thereby; (b)
CertainTeed and the Surviving Company shall periodically, as requested,
advance to such Indemnified Party his, her or its legal and other expenses
(including the cost of investigation and preparation incurred in connection
therewith) to the extent such Indemnified Party is indemnified pursuant to the
Merger Agreement, unless it is ultimately determined by a court of competent
jurisdiction that such Indemnified Party is not entitled to indemnification
hereunder; and (c) CertainTeed and the Surviving Company shall be subrogated
to any rights any Indemnified Party may have with respect to any amounts paid
to or on behalf of such Indemnified Party by CertainTeed and the Surviving
Company pursuant to the Merger Agreement.
 
  Discussions with Certain Executive Officers. CertainTeed has had preliminary
discussions with Messrs. Maloof and Anthony regarding their continued
employment with the Surviving Company on terms which have yet to be decided,
but these discussions have not yet resulted in any written commitments by any
of the parties.
 
  The Board was aware of the foregoing interests and considered them, among
other matters, in approving the Merger Agreement. Other than as described
above, the Board is not aware of any potential material conflicts of interest
management may have in relation to the Merger.
 
CERTAIN REGULATORY MATTERS
 
  Under the provisions of the HSR Act applicable to the Offer, the acquisition
of Shares under the Offer could only be consummated following the expiration
of a 15-calendar day waiting period following the filing by Saint-Gobain of a
Notification and Report Form with respect to the Offer, unless Saint-Gobain
had received a request for additional information or documentary material from
the Antitrust Division or the FTC prior to the expiration of such period or
unless early termination of the waiting period was granted. Saint-Gobain made
such filing on January 15, 1998. The waiting period under the HSR Act
terminated on January 29, 1998. Therefore, the Company does not believe that
this or any other material regulatory approvals are required for consummation
of the Merger.
 
                                      18

 
  The Antitrust Division and the FTC frequently scrutinize the legality under
the antitrust laws of transactions such as Acquisition Sub's proposed
acquisition of the Company. At any time before or after Acquisition Sub's
acquisition of Shares pursuant to the Offer, the Antitrust Division or the FTC
could take such action under the antitrust laws as it deems necessary or
desirable in the public interest, including seeking to enjoin the consummation
of the Merger or seeking the divestiture of Shares acquired by Acquisition Sub
or the divestiture of substantial assets of the Company or its subsidiaries or
Saint-Gobain or its subsidiaries. Private parties may also bring legal action
under the antitrust laws under certain circumstances. There can be no
assurance that a challenge to the Offer or the Merger on antitrust grounds
will not be made or, if such a challenge is made, of the result thereof.
 
ACCOUNTING TREATMENT
 
  The Merger will be accounted for as a purchase of the Company by CertainTeed
in accordance with generally accepted accounting principles, whereby the
purchase price will be allocated based upon the fair values of the assets
acquired and the liabilities assumed by CertainTeed.
 
FEDERAL INCOME TAX CONSEQUENCES
 
  The following is a summary of certain federal income tax consequences of the
Merger to stockholders of the Company. This summary does not purport to
discuss all income tax consequences of the Merger that may be relevant to
particular stockholders in light of their individual circumstances or to
certain types of stockholders subject to special treatment, such as life
insurance companies, tax-exempt organizations and financial institutions,
persons who are not citizens or residents of the United States or who are
foreign corporations, and stockholders who acquired stock through the exercise
of Company stock options or otherwise as compensation.
 
  The receipt of cash in exchange for Shares pursuant to the Merger, or
pursuant to the exercise of dissenter's appraisal rights, will be a taxable
transaction for federal income tax purposes under the Internal Revenue Code of
1986, as amended (the "Code"), and may also be a taxable transaction under
applicable state, local or foreign income or other tax laws. Generally, for
federal income tax purposes, a stockholder will recognize gain or loss equal
to the difference between the amount of cash received by the stockholder
pursuant to the Merger, or exercise of dissenter's appraisal rights, and the
aggregate tax basis in the Shares sold by the stockholder, or with respect to
which dissenter's rights are exercised, as the case may be. Gain or loss will
be calculated separately for each block of Shares tendered and purchased
pursuant to the Merger, or with respect to which dissenter's appraisal rights
are exercised, as the case may be.
 
  If Shares are held by a stockholder as capital assets, gain or loss
recognized by the stockholder will be capital gain or loss, which will be
long-term capital gain or loss if the stockholder's holding period for the
Shares exceeds eighteen months. Under present law, long-term capital gains
recognized by an individual stockholder will generally be taxed at a maximum
federal marginal tax rate of 20%, and long-term capital gains recognized by a
corporate stockholder will be taxed at a maximum federal marginal tax rate of
35%. In addition, under present law the ability to use capital losses to
offset ordinary income is limited. Stockholders should consult their tax
advisors regarding the applicable rate of taxation and their ability to use
capital losses against ordinary income.
 
  A stockholder that surrenders Shares pursuant to the Merger (or pursuant to
the exercise of dissenter's rights) may be subject to backup withholding
unless the stockholder provides its taxpayer identification number ("TIN") and
certifies that such number is correct or properly certifies that it is
awaiting a TIN, or unless an exemption applies. A stockholder that does not
furnish its TIN may be subject to a penalty imposed by the IRS.
 
  THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL
INFORMATION ONLY AND DOES NOT CONSTITUTE TAX ADVICE. STOCKHOLDERS ARE URGED TO
CONSULT THEIR TAX ADVISORS TO DETERMINE THE PARTICULAR TAX CONSEQUENCES TO
 
                                      19

 
THEM (INCLUDING THE APPLICABILITY AND EFFECT OF THE ALTERNATIVE MINIMUM TAX
AND OF ANY STATE, LOCAL OR FOREIGN INCOME AND OTHER TAX LAWS) OF THE MERGER.
 
EFFECT OF THE MERGER ON THE COMPANY'S STOCKHOLDERS
 
  Consummation of the Merger is contingent upon, among other things, approval
of the Merger by the holders of Common Shares and Preference Shares. After the
Effective Date, the current holders of Common Shares and Preference Shares of
the Company (other than Acquisition Sub) will cease to be stockholders of the
Company. In addition, pursuant to the Merger Agreement, each share of 5% Stock
issued and outstanding at the Effective Date will be called for redemption and
retirement as soon as practicable following the Merger. Therefore, as a result
of the Merger (assuming the redemption of the 5% Stock as required by the
Merger Agreement), the entire equity interest in the Company will be owned by
CertainTeed and the Company's current stockholders will no longer have any
equity interest in the Company and will no longer share in future earnings and
growth of the Company, the risks associated with achieving any such earnings
and growth, or the potential to realize greater value for their shares of
stock through divestitures, strategic acquisitions or other corporate
opportunities that may be pursued by the Company in the future. Instead, each
current holder of the Company's Common Shares and Preference Shares (other
than Acquisition Sub) will have only the right to receive the Common Merger
Consideration or Preference Merger Consideration, as the case may be, or to
seek appraisal rights as described under "--Dissenting Stockholders' Rights"
below.
 
DISSENTING STOCKHOLDERS' RIGHTS
 
  The following discussion is not a complete statement of the law pertaining
to dissenters' rights under the MBCL and is qualified in its entirety by
reference to the full text of Sections 85 through 98 of the MBCL setting forth
the rights of stockholders who object to the Merger. Dissenting stockholders
wishing to exercise such dissenters' rights or to preserve their rights to do
so should review the following discussion and the provisions of Sections 85
through 98 of the MBCL with counsel. A copy of the relevant sections of the
MBCL is attached to this Information Statement as Annex II. The failure of a
dissenting stockholder to comply in a timely and proper manner with the
procedures set forth in the MBCL will result in its loss of dissenters' rights
with respect to the Merger.
 
  Sections 85 through 98 of the MBCL set forth the rights of stockholders of
the Company who object to the Merger. Any holder of Common Shares or
Preference Shares who does not vote in favor of the Merger (including any such
holder who abstains from voting) and who objects to the Merger, and any holder
of the 5% Stock who objects to the Merger, may, if the Merger is consummated,
obtain payment, in cash, for the fair market value of such holder's shares by
complying with the requirements of Sections 85 through 98 of the MBCL. Holders
of Common Shares and Preference Shares are not eligible to exercise their
dissenters' rights unless they are stockholders on the Record Date and have
not voted in favor of the Merger. Holders of the 5% Stock are not eligible to
exercise their dissenters' rights unless they are stockholders on the Record
Date. Except as provided in Section 96 of the MBCL, holders of 5% Stock who
exercise such rights will no longer have the rights of a holder of 5% Stock
and will not have the right to receive any dividend on the 5% Stock which is
paid on or after the date of the Special Meeting.
 
  Before the taking of the vote on the Merger at the Special Meeting, each
dissenting stockholder must file with the Company a written objection to the
Merger stating that the stockholder intends to demand payment in respect of
the shares of any class held by it if the Merger is consummated. A written
objection must be filed with the Company by holders of Common Shares and
Preference Shares who wish to dissent even if they vote against the Merger.
Such written objections should be addressed to: Frank S. Anthony, Clerk, Bird
Corporation, 1077 Pleasant Street, Norwood, Massachusetts 02062.
 
  Within ten days after the Effective Date, the Company must provide written
notice to each dissenting stockholder that the Merger has been consummated. To
exercise dissenters' rights, each dissenting stockholder must, no later than
20 days after the mailing of such notice that the Merger has been consummated,
mail a written demand for payment for such dissenting stockholder's shares.
Such written demands should be sent to: Bird
 
                                      20

 
Corporation, 1077 Pleasant Street, Norwood, Massachusetts 02062, Attention:
Clerk. Subject to the following paragraph, within 30 days following the
expiration of such 20-day period, the Company must pay to each dissenting
stockholder fair value for such dissenting stockholder's shares.
 
  In the event that the Company and any dissenting stockholder are unable to
agree as to fair value within such 30-day period, Section 90 of the MBCL
provides that a court proceeding may be commenced by the Company or the
dissenting stockholder by the filing of a bill in equity, within four months
after the expiration of such 30-day period, in the Superior Court for Norfolk
County, Commonwealth of Massachusetts, demanding a determination of the value
of the shares of all dissenting stockholders who have not agreed with the
Company as to the fair value of their shares.
 
  All dissenting stockholders will be parties to any court proceeding which is
commenced either by the Company or by a dissenting stockholder. The relief
sought in either case is a decree determining the fair value of the stock of
all dissenting stockholders and ordering payment by the Company of that value
with interest from the date of the meeting at which the Merger is approved in
exchange for the transfer to the Company of the certificates representing the
stock held by the dissenting stockholders, if such stock is certificated, or,
if uncertificated, an instruction transferring such stock to the Company. Such
determination of value will be made as of the day preceding the date of the
meeting at which the Merger is approved, and will be exclusive of any element
of value arising from the expectation of consummation of the Merger.
 
  A negative vote on the Merger does not constitute a "written objection" to
be filed by a dissenting stockholder. A dissenting stockholder's abstention
from voting on the Merger or failure to specify any vote on the accompanying
proxy will not constitute a waiver of such stockholder's rights under Sections
85 through 98 of the MBCL, provided that a written objection has been properly
filed. A vote in favor of the Merger will constitute a waiver of such
stockholder's dissenters' rights, however, even if a written objection has
been filed.
 
  A dissenting stockholder's objections to the Merger or demand for payment
for its shares may be made by facsimile transmission, provided such facsimile
is confirmed by a written objection or demand, as the case may be, sent by
certified or registered mail to the address specified above within 24 hours
after transmission of the facsimile. Facsimile communications should be
addressed to: Bird Corporation, Attention: Clerk, and the appropriate
facsimile connection is to (781) 769-0434.
 
  For a discussion of the Federal income tax consequences of receipt of
payment for shares upon exercise of dissenters' rights, see "THE MERGER--
Federal Income Tax Consequences."

                             THE MERGER AGREEMENT
 
  The following is a summary of the terms and conditions of the Merger
Agreement. Any references to the Merger Agreement set forth below or included
elsewhere in this Information Statement are qualified in their entirety by
reference to the Merger Agreement (attached hereto as Annex I) which is
incorporated herein by reference. Terms which are not otherwise defined in
this summary shall have the meanings set forth in the Merger Agreement.
Stockholders are strongly advised to read the Merger Agreement in its entirety
prior to voting.
 
GENERAL
 
  The Merger Agreement provides that following the satisfaction or waiver of
the conditions described below under "--Conditions to the Merger," Acquisition
Sub will be merged with and into the Company, and each then outstanding Share
(other than Shares held by stockholders who perfect their appraisal rights
under Massachusetts law, Shares held in the Company's treasury, and Shares
held by Acquisition Sub or CertainTeed) will be converted into the right to
receive an amount in cash equal to (in the case of Common Shares) $5.50 per
Common Share and (in the case of Preference Shares) $20, without adjustment
for any dividends accrued and unpaid through the Effective Date per Preference
Share. All outstanding shares of the Company's 5% Stock will remain
outstanding after the Merger and will be called for redemption and retirement
as soon as practicable following the Merger at a price equal to $110 per
share, plus all accrued and unpaid dividends through the date of redemption
and retirement.
 
EFFECTIVE DATE OF THE MERGER
 
  The Effective Date will be such time as the articles of merger ("Articles of
Merger") are filed with the Secretary of State of the Commonwealth of
Massachusetts in accordance with the provisions of Section 78 of the MBCL. The
Articles of Merger will be filed with the Secretary of State of the
Commonwealth of Massachusetts on the Closing Date. The term "Closing Date"
means (i) as soon as practicable after the latest to occur of (a) the date on
which the shareholders of the Company shall have approved the Merger, or (b)
the date of satisfaction of all other conditions to the closing of the Merger
set forth in the Merger Agreement, the satisfaction of which is not waived; or
(ii) on such other date as CertainTeed, Acquisition Sub, and the Company may
mutually agree upon for the closing of the Merger.
 
EXCHANGE OF CERTIFICATES AND PAYMENT OF CASH MERGER CONSIDERATION
 
  CertainTeed and the Company have selected ChaseMellon Shareholder Services
LLC to act as the Paying Agent for the purpose of exchanging certificates
theretofore representing Common Shares and Preference Shares. CertainTeed will
make available to the Paying Agent on a timely basis after the Effective Date
funds necessary to make the payments provided for in the Merger Agreement to
the holders of outstanding Common Shares and Preference Shares. The Paying
Agent will agree to hold such funds in trust for the benefit of the former
stockholders of the Company and deliver such funds in accordance with the
terms of the Merger Agreement and the terms of a paying agency agreement (the
"Paying Agency Agreement") to be entered into by and between the Paying Agent
and CertainTeed.
 
  The Merger Agreement provides that prior to or at the Effective Date, the
Paying Agent will mail to each record holder of an outstanding certificate or
certificates which, immediately prior to the Effective Date, represented
Shares (the "Certificates"), a form letter of transmittal (which will 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) (the "Transmittal Letter") and instructions for use in effecting
the surrender of the Certificates for payment therefor. Upon surrender to the
Paying Agent of a Certificate, together with such Transmittal Letter duly
executed, the holder of such Certificate will be entitled to receive in
exchange for each Share represented by such Certificate, the Common Merger
Consideration or Preference Merger Consideration, as the case may be, and such
Certificate will be canceled upon receipt by the holder of such Certificate of
the Common Merger Consideration or Preference Merger Consideration, as the
case may be. No interest will be paid or accrued on the Common Merger
Consideration or Preference Merger Consideration payable upon the surrender of
such Certificates.
 
                                      22

 
  If payment is to be made to a person other than the person in whose name the
Certificate surrendered in exchange therefor is registered, it will be a
condition of payment of the Common Merger Consideration or Preference Merger
Consideration, as the case may be, that the Certificate so surrendered be
properly endorsed or accompanied by appropriate stock powers, in either case
signed exactly as the name of the record holder appears on such Certificate,
and is otherwise in proper form for transfer, and that the person requesting
such payment will pay any transfer or other taxes required by law as a result
of such payment to a person other than the record holder of the Certificate
surrendered, or will establish to CertainTeed's satisfaction that such tax has
been paid or is not applicable.
 
  The consideration payable upon the surrender for exchange of Certificates in
accordance with the terms of the Merger Agreement will be deemed to have been
paid in full satisfaction of all rights pertaining to the Shares theretofore
represented by such Certificates, and there shall be no further registration
of transfers on the stock transfer books of the Surviving Company of the
Shares which were outstanding immediately prior to the Effective Date.
 
  The Merger Agreement further provides that after the Effective Date there
will be no further transfers on the stock transfer books of the Surviving
Company of Shares which are outstanding at the Effective Date. If, after the
Effective Date, Certificates are presented for transfer to the Paying Agent or
the Surviving Company, they will be canceled and exchanged for the Common
Merger Consideration or Preference Merger Consideration, as the case may be.
 
  If any Certificates are not surrendered prior to seven years after the
Effective Date (or prior to such earlier date on which such cash payment would
otherwise escheat to or become the property of any governmental unit or
agency), the payment in respect of such Certificate will, to the extent
permitted by applicable law, become the property of the Surviving Company,
free and clear of all claims or interest of any person previously entitled
thereto.
 
DISSENTING STOCKHOLDERS' RIGHTS
 
  The Merger Agreement provides that any issued and outstanding Common Shares,
Preference Shares, and 5% Stock held by any dissenting stockholder who has not
voted such shares in favor of the Merger (except with respect to the 5% Stock)
and who has properly exercised rights to demand payment of the fair value of
such shares in accordance with Section 85 through 98 of the MBCL ("Dissenting
Shares") will not, in the case of the Common Shares or the Preference Shares,
be converted into the Common Merger Consideration or the Preference Merger
Consideration, respectively, as contemplated by the Merger Agreement and will
not, in the case of the 5% Stock, be called for redemption and paid the 5%
Redemption Price as contemplated by the Merger Agreement, but instead the
holder thereof will be entitled only to obtain payment of the fair value of
such Common Shares, Preference Shares or 5% Stock, as the case may be, in
accordance with the provisions of Sections 85 through 98 of the MBCL. The
procedures for exercising rights of appraisal are set forth above under "THE
MERGER--Dissenting Stockholders' Rights." In addition, a copy of Sections 85
through 98, inclusive, of the MBCL is attached hereto as Annex II. If (i) a
dissenting stockholder fails to file, in accordance with Section 86 of the
MBCL, prior to the taking of the vote on the Merger at the Special Meeting, a
written objection to the Merger with a statement of his intention to demand
payment for his shares if the Merger is effected or, after filing such written
objection, votes in favor of the Merger or, after the Company mails notice
that the Merger has been effected, fails to give to the Company a written
demand for payment for his shares in accordance with Section 89 of the MBCL
or, with the written approval of the Company, delivers to the Company a
written withdrawal of such objection or otherwise fails to establish his
entitlement to appraisal rights as provided in Sections 85 through 98 of the
MBCL; or (ii) a court determines that such dissenting stockholder is not
entitled to receive payment for his or her shares or such dissenting
stockholder otherwise loses his or her appraisal rights, then in any of such
cases, each Common Share or Preference Share held of record by such dissenting
stockholder will automatically be converted into and represent only the right
to receive the Common Merger Consideration or the Preference Merger
Consideration, as the case may be, upon the surrender of the Certificate or
Certificates representing such Dissenting Shares and each share of 5% Stock
will remain outstanding and will be entitled only to receive the 5% Redemption
Price upon redemption of the 5% Stock in accordance with the Merger Agreement
and the terms of the 5% Stock.
 
                                      23

 
  The Company will give CertainTeed prompt notice of any demands received by
the Company for payment of the fair value of Dissenting Shares, and
CertainTeed will have the right to participate in all negotiations and
proceedings with respect to such demands. The Merger Agreement provides that
the Company shall not, except with the prior written consent of CertainTeed,
make any payment (except to the extent that any such payment is made pursuant
to a court order) with respect to, or settle or offer to settle, any such
demands.
 
CONDITIONS TO THE MERGER
 
  Conditions to the Obligations of CertainTeed and Acquisition Sub. The
obligations of CertainTeed and Acquisition Sub under the Merger Agreement are
subject to the satisfaction, on or prior to the Closing Date, of the
condition, which may be waived by CertainTeed and Acquisition Sub except as
otherwise provided by law, that no statute, rule, regulation, executive order,
decree, temporary restraining order, preliminary or permanent injunction or
other order or legal restraint or prohibition enacted, entered, promulgated,
enforced, issued or deemed applicable to the Merger or the transactions
contemplated thereby shall be in effect, or any other action shall be taken by
any governmental authority or court, in each case preventing the consummation
of the Merger or the transactions contemplated thereby.
 
  Conditions to the Obligations of the Company. The obligations of the Company
under the Merger Agreement are subject to the satisfaction, on or prior to the
Closing Date, of each of the following conditions, each of which may be waived
by the Company except as otherwise provided by law, (i)(a) all corporate
action necessary by Acquisition Sub and CertainTeed to authorize the
execution, delivery and performance of the Merger Agreement and the
consummation of the transactions contemplated by the Merger Agreement shall
have been duly and validly taken, Acquisition Sub shall have full right and
power to merge on the terms provided in the Merger Agreement and the Company's
stockholders shall have approved the Merger at the Special Meeting called for
that purpose; and (b) all consents, approvals and authorizations from third
persons and governmental authorities identified in the Schedules to the Merger
Agreement required to consummate the transactions contemplated by the Merger
Agreement shall have been obtained; and (ii) no judicial, administrative or
arbitration order, award, judgment, writ, injunction or decree shall have been
entered by a governmental authority with proper jurisdiction and not revised
prohibiting the Merger, and no legal action shall have been instituted by any
governmental authority challenging the Merger which if successful would
prohibit the consummation of the Merger.
 
  TERMINATION OF THE MERGER AGREEMENT. Notwithstanding approval of the Merger
Agreement and the transactions contemplated thereby by the stockholders of the
Company, the Merger Agreement may be terminated, and the Merger abandoned, at
any time prior to the Effective Date:
 
    (A) by mutual consent of CertainTeed, Acquisition Sub and the Company;
 
    (B) by CertainTeed or Acquisition Sub if any of the conditions to the
  obligations of CertainTeed and Acquisition Sub to consummate the Merger
  becomes impossible to fulfill and shall not have been waived or deemed
  waived in accordance with the Merger Agreement; or
 
    (C) by the Company if any of the conditions to the obligations of the
  Company to consummate the Merger shall become impossible to fulfill and
  shall not have been waived in accordance with the terms of the Merger
  Agreement.
 
  Notwithstanding any provisions to the contrary in the Merger Agreement, (i)
the sole remedy of CertainTeed or Acquisition Sub for a breach by the Company
of any representation or warranty set forth in the Merger Agreement shall be
the termination of the Merger Agreement (if permitted by the Merger Agreement)
unless such breach was made with the actual knowledge of the President of the
Company or the Vice President and General Counsel of the Company, after due
inquiry of other managerial employees of the Company who would be reasonably
expected to have knowledge as to the matter represented (a "Company Willful
Misrepresentation"); and (ii) the sole remedy of the Company for a breach by
CertainTeed or Acquisition Sub of any representation or warranty set forth in
the Merger Agreement shall be the termination of the Merger

Agreement (if permitted by the Merger Agreement) unless such breach was made
with the actual knowledge of the President or Executive Vice President of
CertainTeed, after due inquiry of other managerial employees of CertainTeed
who would be reasonably expected to have knowledge as to the matter
represented (a "CertainTeed Willful Misrepresentation").
 
  PROCEDURE FOR TERMINATION AND AMENDMENT. The Merger Agreement provides that
the termination or amendment of the Merger Agreement pursuant to the Merger
Agreement requires, in the case of the Company, action by its Board or the
duly authorized designee of its Board in order to be effective. Because,
pursuant to the Merger Agreement, Acquisition Sub's designees have been
appointed to the Board of the Company as provided in the Merger Agreement, the
affirmative vote of at least a majority of the Continuing Directors (as
defined below) will be required for the Company to agree to amend, waive
compliance with or terminate the Merger Agreement.
 
  FEES AND EXPENSES. Except with respect to the circumstances described below,
the Merger Agreement provides that each of Acquisition Sub, CertainTeed and
the Company will bear its own costs, fees and expenses in connection with the
negotiation, execution, delivery and performance of the Merger Agreement and
the consummation of the Offer and the Merger.
 
  DIRECTORS. Pursuant to the Merger Agreement, as a result of the consummation
of the Offer, Acquisition Sub is entitled to designate at least a majority of
the members of the Board of Directors of the Company. On February 17, 1998,
the Board accepted the resignations of Charles S. Bird, III, Herbert I.
Corkin, Loren R. Watts and R. Keith Long as directors. The remaining
directors, Frank S. Anthony, Antonio J. Lorusso, Jr. and Richard C. Maloof,
then appointed Acquisition Sub's designees (any director so designated by
Acquisition Sub, a "Designated Director"), George B. Amoss, Gianpaolo Caccini,
James E. Hilyard and Bradford C. Mattson, to fill the vacancies created by
such resignations. The Company, CertainTeed and Acquisition Sub are required
by the Merger Agreement to use their respective best efforts to cause at least
three members of the Company's Board of Directors at all times prior to the
Effective Time to be Continuing Directors. "Continuing Director" means (a) any
member of the Company's Board of Directors on the date of the Merger
Agreement, (b) any member of the Company's Board of Directors who is not an
employee or director or affiliate of, and not a Designated Director or other
nominee of, Acquisition Sub or CertainTeed or their respective subsidiaries,
and (c) any successor of a Continuing Director who is (i) not an employee or
director or affiliate of, and not a Designated Director or other nominee of,
Acquisition Sub or CertainTeed or their respective subsidiaries and (ii)
recommended to succeed such Continuing Director by at least a majority of the
then Continuing Directors.
 
  STOCK OPTIONS. The Merger Agreement provides that, with respect to unexpired
stock options, whether or not exercisable at the Effective Date, including
stock appreciation rights relating thereto, outstanding on the Effective Date
which have been issued pursuant to the Company's 1982 Stock Option Plan, the
Company's 1992 Option Plan or the Company's Non-Employee Directors Option
Plan, each such stock option with an exercise price less than the Common Price
(an "Eligible Option") shall, by virtue of the Merger and without any action
on the part of the holder thereof, be converted into the right to receive, for
each Common Share subject thereto, a cash payment without interest equal to
the Common Price, less the per share exercise price of each such stock option.
Such stock options will be canceled upon such cash payment following the
Merger. Any stock option with an exercise price equal to or greater than the
Common Price (an "Ineligible Option") shall be canceled upon the Effective
Date without payment of any consideration. The Merger Agreement requires the
Company to use its best efforts to amend each outstanding Stock Option issued
under the Company's 1982 Option Stock Plan, the Company's 1992 Stock Option
Plan, and the Company's Non-Employee Directors Option Plan to effect the
transactions contemplated by the Merger Agreement, including the cancellation
of the stock options in connection with the Merger in accordance with the
foregoing. The Company has informed Acquisition Sub that all options have been
so amended. Each Common Share issued by the Company but not yet vested
pursuant to the Company's Savings Plan shall, in connection with the Merger,
become vested in the person to whose account such Common Share was issued and
converted into the right to receive the Common Price pursuant to the Merger
Agreement.
 
                                      25

 
  The Company has informed Acquisition Sub that, as of January 12, 1998, there
were no Common Shares held in escrow pursuant to the Company's Long Term
Incentive Compensation Plan (the "LTIP"), and the LTIP has been terminated.
Immediately following the Effective Date, the Company's 1982 Option Plan, 1992
Option Plan and Non-Employee Directors Option Plan shall be terminated and no
further stock awards or stock options will be granted thereunder from and
after the date of the Merger Agreement.
 
  INDEMNIFICATION AND INSURANCE. In the Merger Agreement, CertainTeed and
Acquisition Sub have agreed that all rights to indemnification in existence as
of the date of the Merger Agreement in favor of the directors or officers of
the Company and its subsidiaries (the "Indemnified Parties") as currently
provided in their respective certificates or articles of incorporation or
organization and by-laws or in any agreements, contracts or arrangements with
the Company or any of its subsidiaries in effect as of the date of the Merger
Agreement and previously furnished to CertainTeed and to the extent not in
violation of applicable state law, shall survive the Merger and shall continue
in full force and effect for a period of five years from the Effective Date;
provided that, in the event any claim or claims are asserted or made within
such five year period, all rights to indemnification in respect of any such
claim or claims shall continue until the disposition of any and all such
claims. In addition, the Merger Agreement provides that, to the extent
currently provided in the certificates or articles of incorporation or
organization and by-laws of the Company and its subsidiaries and Massachusetts
law, or agreements, contracts or arrangements disclosed to CertainTeed with
the Company or any of the subsidiaries, in the event that any Indemnified
Party becomes involved in any capacity in any action, proceeding or
investigation in connection with any matter, including the transaction
contemplated by the Merger Agreement, occurring prior to, and including, the
Effective Date, or otherwise relating to or arising out of such matters,
CertainTeed or the Surviving Company will periodically advance to such
Indemnified Party his or her legal and other expenses (including the costs of
any investigation and preparation incurred in connection therewith).
 
  The Merger Agreement provides that CertainTeed will use all reasonable
efforts to maintain in effect, or shall cause the Surviving Corporation to use
all reasonable efforts to maintain in effect, for two years after the
Effective Date, directors' and officers' liability insurance ("D&O Insurance")
covering those persons covered by the Company's directors' and officers'
liability insurance on the date of the Merger Agreement or the Effective Date
and which is substantially equivalent in terms of coverage and amount as the
Company has in effect on the Effective Date so long as such insurance is
available and the annual premium therefor would not be in excess of $166,000
(the "Maximum Premium"). If the existing D&O Insurance expires, is terminated
or canceled during such two-year period, CertainTeed shall use all reasonable
efforts to cause to be obtained as much D&O Insurance as can be obtained for
the remainder of such period for an annualized premium not in excess of the
Maximum Premium, on terms and conditions no less advantageous than the
existing D&O Insurance.
 
  The Merger Agreement further provides that (a) any Indemnified Party wishing
to claim indemnification pursuant to the Merger Agreement, upon learning of
any legal action, suit, investigation, inquiry or proceeding by any
governmental authority or other person, shall promptly notify CertainTeed and
the Surviving Company with respect thereto, but the failure to so notify shall
not relieve CertainTeed or the Surviving Company of any liability it may have
to such Indemnified Party under the Merger Agreement except to the extent that
CertainTeed and the Surviving Company are materially prejudiced thereby, (b)
CertainTeed and the Surviving Company shall periodically, as requested,
advance to such Indemnified Party his, her or its legal and other expenses
(including the cost of investigation and preparation incurred in connection
therewith) to the extent such Indemnified Party is indemnified pursuant to the
Merger Agreement, unless it is ultimately determined by a court of competent
jurisdiction that such Indemnified Party is not entitled to indemnification
hereunder, and (c) CertainTeed and the Surviving Company shall be subrogated
to any rights any Indemnified Party may have with respect to any amounts paid
to or on behalf of such Indemnified Party by CertainTeed and the Surviving
Company pursuant to the Merger Agreement.
 
  REPRESENTATIONS AND WARRANTIES. The Merger Agreement contains various
customary representations and warranties. The Merger Agreement requires that
CertainTeed, Acquisition Sub and the Company shall each
 
                                      26

 
take such action as is reasonably necessary to render their respective
representations and warranties accurate on and as of the Effective Date.
Without limiting the foregoing, the Merger Agreement provides that the Company
shall take any action required by CertainTeed to ensure the accuracy of its
representations pertaining to Massachusetts' anti-takeover laws.
 
  THE STOCKHOLDER AGREEMENT. Pursuant to a stockholder agreement executed
January 12, 1998, the directors (the "Selling Stockholders") of the Company
unconditionally agreed to tender into the Offer, and not to withdraw
therefrom, the 1,670,657 Common Shares and 132,200 Preference Shares that they
owned on January 12, 1998, together with any Shares they acquired after such
time, including upon the exercise of stock options. Pursuant to this
stockholder agreement, each of the Selling Stockholders tendered into the
Offer all Common Shares and Preference Shares owned by him.
 
  PLANS FOR THE COMPANY. Saint-Gobain and its affiliates currently intend that
the Company will continue its present manufacturing operations in
Massachusetts and will continue to operate under its present corporate name,
as a wholly owned subsidiary of CertainTeed. CertainTeed has had preliminary
discussions with Richard C. Maloof, the President of the Company, and Frank S.
Anthony, the Vice President, General Counsel and Corporate Secretary of the
Company, regarding their continued employment with the Surviving Company on
terms which have yet to be decided, but these discussions have not yet
resulted in any written commitments by any of the parties.
 
  Except for the Merger, none of Acquisition Sub, CertainTeed or Saint-Gobain
has any current plans or proposals that relate to, or would result in, any
extraordinary corporate transaction involving the Company, such as a merger,
reorganization or liquidation involving, the Company or any of its
subsidiaries to any unaffiliated third party.
 
  APPRAISAL RIGHTS. If the Merger is consummated, holders of outstanding
Common Shares, Preference Shares, and 5% Stock on the Effective Date will have
certain rights pursuant to the provisions of Sections 85 through 98,
inclusive, of the MBCL to dissent and demand appraisal of their shares. Under
Sections 85 through 98, inclusive, of the MBCL, dissenting stockholders who
comply with the applicable statutory procedures will be entitled to receive a
judicial determination of the fair value of their shares (exclusive of any
element of value arising from the accomplishment or expectation of the Merger)
and to receive payment of such fair value in cash, together with a fair rate
of interest, if any. Any such judicial determination of the fair value of
shares could be based upon factors other than, or in addition to, the price
per share to be paid in the Merger or the market value of the shares. The
value so determined could be more or less than the price per share to be paid
in the Merger.
 
  The foregoing summary of Sections 85 through 98, inclusive, of the MBCL does
not purport to be complete and is qualified in its entirety by reference to
Sections 85 through 98, inclusive, of the MBCL. Failure to follow the steps
required by Sections 85 through 98, inclusive, of the MBCL for perfecting
appraisal rights may result in the loss of such rights.
 
  GOING PRIVATE TRANSACTIONS. The SEC has adopted Rule 13e-3 under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), which is
applicable to certain "going private" transactions. Acquisition Sub does not
believe that Rule 13e-3 will be applicable to the Merger unless the Merger is
consummated after February 13, 1999, one year after the expiration of the
Offer. If applicable, Rule 13e-3 requires, among other things, that certain
financial information concerning the fairness of the Merger and the
consideration offered to minority stockholders in such transaction be filed
with the SEC and disclosed to stockholders prior to the consummation of the
Merger.
 
  DIVIDENDS AND DISTRIBUTIONS. The Merger Agreement provides that the Company
shall not declare and pay or set apart for payment any accumulated dividends
on the Common Shares, the 5% Stock or the Preference Shares. Accordingly, the
Company did not declare the February 15, 1998 dividend on the Preference
Shares or the March 1, 1998 dividend on the 5% Stock.

            CERTAIN INFORMATION WITH RESPECT TO THE COMPANY'S STOCK
 
  As a result of the completion of the Offer, the Company withdrew the Common
Shares and the Preference Shares from the Nasdaq Stock Market, effective at
the close of business on March 3, 1998. Prior to that time, the Common Shares
were quoted on the Nasdaq National Market under the symbol BIRD and the
Preference Shares, were quoted on the Nasdaq SmallCap Market under the symbol

  On January 12, 1998, the last reported bid quotation of the Preference
Shares on the Nasdaq SmallCap Market was $14 per share, and there were

  The Company did not pay cash dividends on the Common Shares in 1996 and 1997
and has not paid cash dividends on the Common Shares in 1998 through the date
of this Information Statement. Under the terms of the loan agreement between
the Company and Fleet National Bank, the Company has agreed that it will
refrain from paying cash dividends on the Common Shares without prior approval
from Fleet National Bank.
 
  The Company is currently in arrears with respect to six dividend payments on
the Preference Shares. The aggregate amount of accrued and unpaid dividends on
the Preference Shares as of March 3, 1998 is $2.77 per share.
 
  The Merger Agreement provides that the Company shall not declare and pay or
set aside for payment any accumulated dividends on the Common Shares, the 5%
Stock or the Preference Shares. Accordingly, the Company did not declare the
February 15, 1998 dividend on the Preference Shares or the March 1, 1998
dividend on the 5% Stock.

  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                                  OPERATIONS
 
ACQUISITION BY CERTAINTEED
 
  On February 16, 1998 Acquisition Sub, a wholly-owned subsidiary of
CertainTeed, an indirect wholly-owned subsidiary of Saint-Gobain, accepted for
payment pursuant to the Offer 3,991,022 Common Shares, or approximately 95% of
the Common Shares outstanding, and 772,735 Preference Shares, or approximately
95% of the Preference Shares outstanding, at a price of $5.50 per Common Share
and $20 per Preference Share without any adjustment for dividends accrued and
unpaid through the date of the expiration of the Offer on February 13, 1998.
 
  As a result of the completion of the Offer, CertainTeed owns, through
Acquisition Sub, all but 170,354 shares of the outstanding Common Shares and
all but 41,565 of the outstanding Preference Shares. The Common Shares no
longer meet the continuing inclusion requirements for Nasdaq National Market
securities, and there is little or no market for either the Common Shares or
the Preference Shares. Accordingly, the Company withdrew from Nasdaq Stock
Market listing the Common Shares and the Preference Shares, effective at the
close of business on March 3, 1998.
 
  The Offer was the first step in the acquisition of the Company by
CertainTeed contemplated by the Merger Agreement between the Company,
CertainTeed and Acquisition Sub. The second step in the transaction will be
the Merger, pursuant to which Acquisition Sub will be merged with and into the
Company, with the Company surviving the Merger as a wholly owned subsidiary of
CertainTeed. Upon the effectiveness of the Merger, each outstanding Common
Share (other than shares held by stockholders who perfect their appraisal
rights under Massachusetts law, shares held in the Company's treasury, and
shares held directly by Acquisition Sub or CertainTeed) will be converted into
the right to receive $5.50 in cash, and each Preference Share (other than
shares held by stockholders who perfect their appraisal rights under
Massachusetts law, shares held in the Company's treasury, and shares held
directly by Acquisition Sub or CertainTeed) will be converted into the right
to receive $20 in cash, which amount will not be adjusted for any dividends
accrued and unpaid through the date of the consummation of the Merger.
Outstanding options to acquire Common Shares with an exercise price of less
than $5.50 per share will be converted into the right to receive a cash
payment equal to the number of shares purchasable upon exercise of the option
multiplied by the difference between $5.50 and the exercise price. The
Company's outstanding 5% Stock will remain issued and outstanding upon the
effectiveness of the Merger and will be called for redemption and retirement
as soon as is practicable thereafter at a price equal to $110, plus all
accrued and unpaid dividends thereon as of the date of redemption and
retirement. The total consideration for CertainTeed's acquisition of the
Company is approximately $40 million, including payment for the Common Shares
and the Preference Shares pursuant to the Offer and Merger and for the 5%
Stock upon redemption, but excluding outstanding indebtedness of the Company.
 
  The closing of the Merger is anticipated during the second quarter of 1998,
following distribution of this Information Statement to the Company's
stockholders and approval of the Merger Agreement at a special meeting of
stockholders. The consummation of the Merger is subject to approval of the
Merger Agreement by at least 66 2/3% of the outstanding Common Shares and at
least 66 2/3% of the outstanding Preference Shares. As a result of the
completion of the Offer, Acquisition Sub has sufficient voting power to effect
the Merger without the vote of any other stockholder of the Company.
 
FINANCIAL CONDITION
 
  As of December 31, 1997, the Company had cash and cash equivalents on hand
totaling $784,000 and total debt of approximately $2 million. Letters of
credit outstanding as of December 31, 1997 totaled $805,000. The Company's
external financing needs were augmented by the ability of its wholly owned
subsidiary, Bird Incorporated, to borrow under a new three year $15,000,000
Revolving Credit and Security Agreement (the "Credit Agreement") dated July 8,
1997 between Bird Incorporated and Fleet National Bank ("Fleet"). Up to
 
                                      32

 
$3 million of the revolving credit facility could be used for letters of
credit. This agreement superseded the Loan and Security Agreement dated
November 30, 1994, as amended March 8, 1995, between Bird Incorporated and
Fleet Capital Corporation.
 
  Borrowings by Bird Incorporated under the Credit Agreement were guaranteed
by the Company and the Company's other subsidiaries and were secured by
accounts receivable and inventory. The revolving credit line availability was
determined with reference to a percentage of accounts receivable and
inventory. Under the Credit Agreement, the availability calculation did not
allow borrowings to the full extent of the revolving credit commitment due to
the seasonality of the building materials manufacturing business. As of
December 31, 1997, an aggregate of $5,864,000 was available to the Company
under the terms of the Credit Agreement, of which $3,358,000 remained
available, net of current borrowings and letters of credit.
 
  Interest on the Credit Agreement accrued at the Fleet base rate less 1/2%
(as specified in such Credit Agreement) or the London Interbank Offering Rate
("LIBOR") plus 1 1/2% at the Company's election. The interest rates on
outstanding borrowings at December 31, 1997 were 8.25% on a $700,000, 7 day
LIBOR loan expiring January 5, 1998 and 7.46875% on a $1 million, 30 day LIBOR
loan expiring on January 28, 1998.
 
  The Credit Agreement contained certain financial and operating covenants and
placed limits on the Company's capital expenditures. As of December 31, 1997,
the Company was in default under Section 5.9 of the Credit Agreement as a
result of failing to achieve the minimum fixed charge coverage ratio for the
fourth quarter of 1997. As a result of the change of control on February 16,
1998 resulting from completion of the Offer, the terms of the Credit Agreement
required repayment of indebtedness. On February 18, 1998, the Company repaid
all indebtedness with the exception of outstanding letters of credit
aggregating $805,000. Fleet will maintain its security interest in the assets
of the Company until revocation of the letters of credit occurs, which is
expected in the second quarter of 1998.
 
  Net cash and cash equivalents decreased during fiscal 1997 by approximately
$1.5 million primarily due to working capital needs. The Company generated
cash of $1.6 million from operating activities, including $2.8 million from
depreciation and amortization and $1.6 million from decreased accounts
receivable, primarily offset by $2.5 million in increased liabilities
unrelated to financing activities.
 
  The Company used $1.3 million for capital expenditures for the period ended
December 31, 1997 as compared to $1.1 million of cash used in the same period
in the prior year.
 
  The net cash used by financing activities changed by approximately $2.7
million from the prior year. Cash used by financing activities during 1997 was
primarily due to approximately $477,000 of net debt repayments and
approximately $1.5 million of dividend payments as compared to 1996 when the
Company had net debt repayments of approximately $3.6 million and
approximately $1.2 million of dividend payments.
 
  The Company is dependent upon computer systems for certain phases of its
operations, including financial accounting and production. Since some of the
Company's computer software programs and hardware recognize only the last two
digits of the year in any date ("97" for 1997), some programs may fail to
operate properly in 1999 or 2000 if the software or hardware is not
reprogrammed or replaced. The Company intends to spend approximately $65,000
over the next two years to upgrade its computer systems to address the
problem. The Company believes that the cost of fixing the "Year 2000 Problem"
will not have a material effect on the Company's current financial condition
or results of operations.
 
ENVIRONMENTAL MATTERS
 
  The Company monitors its compliance with environmental regulations on an
ongoing basis. The Company's general counsel receives environmental site
assessments from the operating managers responsible for site environmental
compliance. Appropriate action is undertaken where needed. When environmental
claims are asserted against the Company, the claims are evaluated by the
Company's general counsel and operating
 
                                      33

 
management in conjunction with external legal counsel and environmental
engineers as necessary, and action is taken with respect to all known sites,
as appropriate. The Company is currently engaged in proceedings relating to or
has received notice of the following environmental matters:
 
  On June 21, 1994, the Arizona Department of Environmental Quality ("ADEQ")
issued a notice of violation ("NV") to Southwest Roofing Supply, a previously
owned division of the Company ("Southwest"), which directed Southwest to
conduct a site investigation of property formerly leased by Southwest. A
consent order between the ADEQ and the Company was issued on September 23,
1994. Pursuant to the order, the Company agreed to submit a work plan with a
view to remediating the soil and groundwater that may have been contaminated
by leaks from an underground storage tank previously removed by the Company.
On December 23, 1996, the consent order was closed between the ADEQ and the
Company; however, the remediation work must still be completed. The Company's
management believes that the net remediation cost to the Company will be
approximately $150,000 after anticipated reimbursement from the Arizona State
Assurance Fund as described below. As of December 31, 1997, the Company had a
reserve of $150,000 for the estimated cost of clean-up. The Company believes
that $250,000 will be reimbursed to the Company from the Arizona State
Assurance Fund administered by the ADEQ in accordance with Arizona law and
regulation.
 
  In 1986, the Company, along with numerous other companies, was named by the
EPA and other governmental agencies responsible for regulation of the
environment as a Potentially Responsible Person ("PRP") pursuant to the
Comprehensive Environmental Response, Compensation and Liability Act, as
amended, 42 U.S.C. Section 9601, et seq. ("CERCLA") in connection with
hazardous substances at a site known as the Fulton Terminal Superfund site
located in Fulton, Oswego County, New York. On September 28, 1990, the Company
and a number of other PRPs reached a negotiated settlement with the EPA
pursuant to which the settling PRPs agreed to pay the costs of certain
expenses in connection with the proceedings and to pay certain other expenses,
including the costs and expenses of administering a trust fund to be
established by the settling PRPs. The settlement agreement is embodied in a
consent decree filed with the United States District Court for the Western
District of New York and fixed the Company's proportionate share of the total
expenses. The soil has been cleaned up and the groundwater is now being
treated. The remaining cost to the Company of the remedial work and other
expenses covered by the settlement agreement is estimated to be approximately
$200,000 payable over the next three years. Under a cost-sharing arrangement
set forth in a consent decree with the EPA, the other PRPs have agreed to
incur 83% of the aggregate cost of remediation of this site. At December 31,
1997, the Company had a reserve of $200,000 to cover the estimated cost of the
Company's remaining proportionate share (i.e., 17%) of the cost to clean up
the groundwater. Based on information currently available to the Company,
management believes that it is probable that the major responsible parties
will fully pay the cost apportioned to them. Management believes that, based
on its financial position and the estimated accrual recorded, the remediation
expense with respect to this site is not likely to have a material adverse
effect on the consolidated financial position or results of operations of the
Company.
 
  The Company has owned and operated a sanitary landfill since the late 1960's
used exclusively by the Company's roofing plant for the disposal of its own
manufacturing process waste, primarily asphalt roofing materials. No hazardous
or other specially regulated wastes have been disposed of at this site. As a
result of a 1995 regulatory decision by the Massachusetts Department of
Environmental Protection ("D.E.P.") to disallow the continued operation of all
unlined landfills, the Company chose not to seek to renew its operating permit
at the state or local level which expired at the end of August 1997. To
continue to operate the landfill would be of no financial benefit over the
existing outside disposal alternatives, given the new regulatory requirements
and the minimal quantities of waste being disposed of presently. Therefore, as
a result of this decision, the Company has begun negotiating a landfill
closure plan with the D.E.P. which may commence construction in 1998 and be
completed in 1999. As of December 31, 1997, the Company had a reserve of
approximately $800,000 to cover the estimated cost to close the landfill.
Management believes that the closure expense with respect to this site will
not have a material adverse effect on the results of operations or financial
condition of the Company.
 
  The Company has been named as a PRP with respect to certain other sites
which are being investigated by federal or state agencies responsible for
regulation of the environment. As a consequence of its status as a PRP,
 
                                      34

 
the Company may be jointly and severally liable for all of the potential
monetary sanctions and remediation costs applicable to each site. In assessing
the potential liability of the Company at each site, management has
considered, among other things, the aggregate potential clean-up costs of each
site; the apparent involvement of the Company at each site and its prospective
share of the remediation costs attributable thereto; the number of PRPs
identified with respect to each site and their financial ability to contribute
their proportionate shares of the remediation costs for such site; the
availability of insurance coverage for the Company's involvement at each site
and the likelihood that such coverage may be contested; and whether and to
what extent potential sources of contribution from other PRPs or
indemnification by insurance companies constitute reliable sources of recovery
for the Company. Similar consideration has been given in determining the
exposure and potential liability of the Company in connection with other
significant legal proceedings to which the Company is a party. On the basis of
such consideration, management has determined that such environmental matters
will not have a material adverse effect on the Company's financial position or
results of operations.
 
  Since 1981 Bird Incorporated has been named as a defendant in approximately
650 product liability cases throughout the United States by persons claiming
to have suffered asbestos-related diseases as a result of alleged exposure to
asbestos used in products manufactured and sold by Bird Incorporated.
Approximately 150 of these cases are currently pending and costs of
approximately $2 million in the aggregate have been incurred in the defense of
these claims since 1981. Employers Insurance of Wausau ("Wausau") has accepted
the defense of these cases under an agreement for sharing of the costs of
defense, settlements and judgments, if any. At December 31, 1997, the Company
has a reserve of $950,000 to cover the estimated cost of these claims. In
light of the nature and merits of the claims alleged, in the opinion of
management, the resolution of these remaining claims will not have a material
adverse effect on the results of operations or financial condition of the
Company.
 
INSURANCE AND PRODUCT LIABILITY CLAIMS
 
  On April 16, 1996, a class action suit was filed in the Superior Court of
the Commonwealth of Massachusetts against Bird Incorporated, a wholly owned
subsidiary of the Company. The complaint alleges that Bird Incorporated has
knowingly manufactured, distributed and falsely advertised defectively
designed fiber glass based roofing shingles. The complaint sets forth claims
of fraud, negligent misrepresentation, negligence and breach of express and
implied warranty. The Company is currently in the process of defending against
the complaint. The Company has tendered the defense of the action to several
of its insurance carriers, which assumed its defense with reservation of
rights. In the opinion of management, the above matter will not have a
material adverse effect on the Company's financial position or results of
operations.
 
  On June 1, 1993, Wausau commenced an action in the Superior Court for
Norfolk County, Massachusetts, against Bird Incorporated seeking a declaratory
judgment that certain built-up roofing and fiber glass based shingle claims
made against Bird Incorporated were not covered by liability insurance
policies issued by Wausau. Bird Incorporated asserts that the claims are
covered and has answered the complaint. A trial is expected in 1999. In the
opinion of management, the above matter will not have a material adverse
effect on the Company's financial position or results of operations.
 
  The Company is also exposed to a number of other asserted and unasserted
potential claims encountered in the normal course of business. In the opinion
of management, the resolution of such claims will not have a material adverse
effect on the Company's financial position or results of operations.
 
  The Company is a defendant in a number of suits alleging product defects,
the outcome of which management believes will not in the aggregate have a
material impact on the Company's financial position or results of operations.
 
LEGAL MATTERS
 
  In 1992, a subsidiary of the company, Bird Atlantic Corporation ("BAC"),
formerly Atlantic Building Products Corporation, commenced an action against a
former vendor, alleging violation of an exclusive
 
                                      35

 
distributorship without adequate and fair compensation to BAC. A jury trial
was held in November 1995 in the Superior Court of Plymouth County,
Massachusetts. The jury found in favor of BAC and judgment was entered on
January 26, 1996 in the principal amount of approximately $1.8 million. The
award, with interest accruing at 12% per annum, is expected to be in excess of
$3 million and will not be reported as income until collected. Both defendant
and BAC have appealed the judgment.
 
RESULTS OF OPERATIONS
 
  The Company's future prospects and sales are tied solely to one line of
business (roofing manufacturing) which is dependent upon the economy in the
northeastern United States. The Company produces all of its output at a single
plant and relies on one major supplier for glass mat, a critical raw material.
Nevertheless, the Company believes it has significant competitive advantages
in this business. These advantages stem from, and are expected to continue in
light of the Company's leading market share, its low cost production abilities
resulting from a state-of-the-art plant, its internal supply of granules from
its own quarry and granule plant and its asphalt oxidizing plant.
 
 1997 Compared With 1996
 
  Losses from continuing operations before income taxes in 1997 were $977,000
compared to earnings of $2,169,000 in 1996. Net sales decreased 17% from
$51,956,000 to $43,132,000 as compared to fiscal 1996. Mild weather conditions
in the northeastern region of the United States during 1997 unfavorably
affected sales volume. Competitive pricing pressure also had an adverse effect
on sales.
 
  The Company's cost of sales in 1997 compared to 1996 decreased 12.5% from
$43,840,000 to $38,366,000. Such decrease was primarily attributable to lower
sales volume. Cost of sales as percentage of sales was 89% in fiscal 1997
compared to 84.4% in fiscal 1996. The fluctuations related primarily to volume
variances and pricing pressure.
 
  Selling, general and administrative ("SG&A") expenses for fiscal 1997
decreased 2.5% from $5,764,000 to $5,621,000. SG&A expenses as a percentage of
sales increased approximately 2% from year to year, primarily by the result of
lower sales volume in 1997.
 
  Interest expense for fiscal 1997 compared to fiscal 1996 decreased
approximately 31% from $435,000 to $300,000. The decreased interest expense is
attributable to the reduction of debt and lower interest rates.
 
 1996 Compared With 1995
 
  Earnings from continuing operations before income taxes in 1996 were
$2,169,000 compared to earnings of $10,627,000 in 1995. Net sales decreased
4.1% from $54,180,000 to $51,956,000 as compared to 1995, a consequence of the
sale of the Company's window fabrication and vinyl products business units
which had aggregate sales of $10,575,000.
 
  Cost of sales in 1996 as compared to 1995 decreased 8.7% from $48,007,000 to
$43,840,000, primarily the result of the sale of the Company's window
fabrication and vinyl products business units. Cost of sales, stated as a
percentage of net sales, was 84.4% in fiscal 1996 as compared to 88.6% in
fiscal 1995. Improvements in manufacturing efficiency contributed to the
percentage decrease.
 
  Selling, general and administrative ("SG&A") expenses for fiscal 1996
decreased 51.2% from $11,817,000 to $5,764,000. SG&A expenses, as stated as a
percentage of sales, decreased approximately 11% from year to year. The
decrease was attributable to the sale of the Company's window fabrication and
vinyl products business units, reduction in corporate staffing and operating
expenses and reduction in roofing plant expenses.
 
  Other expenses in 1996 were primarily due to $806,000 of costs associated
with a terminated merger agreement.
 
                                      36

 
  Interest expense in 1996 decreased approximately 53% or $492,000 as compared
to 1995. The decrease reflects a reduction of debt with a portion of the
proceeds from the sale of the Company's vinyl products and window fabrication
business units.
 
INFLATION
 
  The Company is continually seeking ways to deal with raw material cost
increases by productivity improvements and cost reduction programs. In recent
years, the Company has not always been able to pass on increased raw material
costs to customers by increasing selling prices because of intense competitive
pressures. The Company has an ongoing program of updating productive capacity
to take advantage of improved technology, and although the cumulative impact
of inflation has resulted in higher costs for replacement of plant and
equipment, these costs have been offset, in part, by productivity savings.

                   ADDITIONAL INFORMATION ABOUT THE COMPANY
 
  The Company is engaged in the manufacture, sale and marketing of roofing
products. Products currently manufactured at the Company's roofing facility
include asphalt shingles and roll roofing for commercial and residential use.
These products are marketed through independent wholesalers, including
wholesalers whose primary customers are roofing contractors.
 
SIGNIFICANT BUSINESS DEVELOPMENT
 
  On February 16, 1998 Acquisition Sub, a wholly owned subsidiary of
CertainTeed, an indirect wholly-owned subsidiary of Saint-Gobain, accepted for
payment pursuant to the Offer 3,991,022 Common Shares, or approximately 95% of
the Common Shares outstanding, and 772,735 Preference Shares, or approximately
95% of the Preference Shares outstanding, at a price of $5.50 per Common Share
and $20 per Preference Share without any adjustment for dividends accrued and
unpaid through the date of the expiration of the Offer, on February 13, 1998.
 
  As a result of the completion of the Offer, CertainTeed owns, through
Acquisition Sub, all but 170,354 shares of the outstanding Common Shares and
all but 41,565 shares of the outstanding Preference Shares. The Common Shares
no longer meet the continuing inclusion requirements for Nasdaq National
Market securities, and there is little or no market for either the Common
Shares or the Preference Shares. Accordingly, the Company withdrew from Nasdaq
Stock Market listing the Common Shares and the Preference Shares, effective at
the close of business on March 3, 1998.
 
  The Offer was the first step in the acquisition of the Company by
CertainTeed contemplated by the Merger Agreement among the Company,
CertainTeed, and Acquisition Sub. The second step in the transaction will be
the Merger, pursuant to which Acquisition Sub will be merged with and into the
Company, with the Company surviving the Merger as a wholly owned subsidiary of
CertainTeed. Upon the effectiveness of the Merger, each outstanding Common
Share (other than shares held by stockholders who perfect their appraisal
rights under Massachusetts law, shares held in the Company's treasury, and
shares held directly by Acquisition Sub or CertainTeed) will be converted into
the right to receive $5.50 in cash, and each Preference Share (other than
shares held by stockholders who perfect their appraisal rights under
Massachusetts law, shares held in the company's treasury, and shares held
directly by Acquisition Sub or CertainTeed) will be converted into the right
to receive $20 in cash, which amount will not be adjusted for any dividends
accrued and unpaid through the date of the consummation of the Merger.
Outstanding options to acquire Common Shares with an exercise price of less
than $5.50 per share will be converted into the right to receive a cash
payment equal to the number of shares purchasable upon exercise of the option
multiplied by the difference between $5.50 and the exercise price. The
Company's outstanding 5% Stock will remain issued and outstanding upon the
effectiveness of the Merger and will be called for redemption and retirement
as soon as is practicable thereafter at a price equal to $110, plus all
accrued and unpaid dividends thereon through the date of redemption and
retirement. The total consideration for CertainTeed's acquisition of the
Company is approximately $40 million, including payment for the Common Shares
and the Preference Shares pursuant to the Offer and Merger and for the 5%
Stock upon redemption, but excluding outstanding indebtedness of the Company.
 
  The closing of the Merger is anticipated during the second quarter of 1998,
following distribution of this Information Statement to the Company's
stockholders and approval of the Merger Agreement at a special meeting of
stockholders. The consummation of the Merger is subject to approval of the
Merger Agreement by at least 66 2/3% of the outstanding Common Shares and at
least 66 2/3% of the outstanding Preference Shares. As a result of the
completion of the Offer, Acquisition Sub has sufficient voting power to effect
the Merger without the vote of any other stockholder of the Company.
 
HOUSING GROUP
 
  Asphalt roofing products are manufactured and sold at the Company's
facilities in Norwood, Massachusetts. Asphalt shingles and roll roofing are
produced by coating a fiberglass mat with a mixture of hot asphalt and
 
                                      38

 
crushed rock (commonly called filler) and covering the coated mat with
Company-manufactured roofing granules. The Company's facilities include a
roofing manufacturing facility, a granule plant, a quarry, an asphalt plant
and a closed private landfill that was for the Company's use only.
 
  The Company's Housing Group produced vinyl siding products at its plant in
Bardstown, Kentucky prior to the sale of such facility in March 1995.
Additionally, the Company sold its interest in Kensington, its joint venture
in the replacement window fabrication business in June 1995.
 
  Net sales of the components of the Housing Group as a percentage of
consolidated net sales of the Company were as follows: sales of asphalt
roofing products, 100% in 1997, 100% in 1996 and 80% in 1995; sales of vinyl
products, 20% in 1995. One customer accounted for slightly more than 15% of
the Company's sales during 1997 and 1996 and 10% during 1995.
 
  The principal geographic markets for the Company's manufactured roofing
products, due to limitations imposed by freight costs, are the northeastern
United States. The building materials business is seasonal to the extent that
outside repair and remodeling and new construction decline during the winter
months. To reduce the impact of this seasonal factor, the Company generally
employs what it believes to be an industry-wide practice of "winter dating",
pursuant to which extended or discounted payment terms are offered to
creditworthy customers who order and accept delivery of roofing products
during specified periods of time in the slow season.
 
 Raw Materials
 
  The principal raw materials used in the manufacture of asphalt roofing
products are fiberglass mat, asphalt saturants and coatings and crushed
granules. The Company's requirements for fiberglass mat are met primarily with
one vendor under an agreement which expires December 31, 1999 with an option
to extend for an additional two years. Fiberglass mat is also generally
available in adequate quantities from a number of outside suppliers. Asphalt
saturants and coatings were, until early 1995, purchased from a major oil
refinery. These materials are also available from other sources at a higher
delivered cost. Since completion of construction of an asphalt plant in
January 1995, the Company has been able to process asphalt at its roofing
facility, thereby reducing its costs and decreasing the potential for
temporary interruptions in its manufacturing operations. The Company can
produce all of its current granule requirements at its granule plant.
 
 Backlog
 
  Order backlog is not a meaningful measure of the Company's building
materials business because there are fewer sales during the last quarter of
the fiscal year and the order-to-shipment cycle is relatively short.
Additionally, it is very rare, at any time, to require more than 30 days from
the receipt of a product order to delivery of the product.
 
 Competition
 
  The building materials business is, to a large degree, a commodities-type
business and is highly competitive with respect to price, delivery terms and
consistent product quality. Many of the Company's competitors are larger and
financially stronger than the Company, but none is dominant in any of its
markets.
 
  The strengths of the Company's asphalt roofing business arise, in part, from
the unique marketing programs the Company directs toward its indirect customer
base, professional roofing contractors, combined with an industry-wide
reputation for providing quality products with a high level of service. The
Company's comprehensive contractor marketing program is designed to support
the position of the Company's contractors in the industry. Such marketing
programs include a special system for in-home sales promotions. Pursuant to
its exclusive certification program, the Company also certifies contractors
who have recorded three (3) successful years in business, who provide the
Company with names of customers for quality checks, sign a letter of ethics,
 
                                      39

 
have a good credit history, warrant their workmanship for two years and attend
annual training meetings. Contractors must be recertified every three years.
Certified contractors are supplied with a wide array of marketing materials,
including customized sample cases, special mailers and custom job site signs.
 
 Intellectual Property
 
  The Company owns a number of trademarks, as well as significant technology
and know-how, which it utilizes in connection with its asphalt roofing
business. The Company believes that its trademarks are strong and well
recognized in the industry.
 
COMPLIANCE WITH CERTAIN ENVIRONMENTAL LAWS
 
  The Company has expended, and expects to continue to expend, funds to comply
with federal, state and local provisions and orders which relate to the
environment. Based on the information available to the Company at this time,
the Company believes that the effect of compliance with these provisions on
the capital expenditures, earnings and competitive position of the Company
will not be material. Proceedings involving environmental matters are
described under "MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS--Environmental Matters."
 
EMPLOYEES
 
  At December 31, 1997, the Company employed 160 people.
 
PROPERTIES
 
  The Company's executive offices are located at its plant in Norwood,
Massachusetts. The Company believes that its plant and facilities, as
described below, are suitable and adequate for its current and anticipated
business. Operating capacity can be increased by additional man hours,
changing product mix, and/or minimal capital investment should the need arise.
The Company's facilities are well maintained, in sound operating condition,
and in regular use.
 
 Roofing Manufacturing Facility
 
  The Company owns its asphalt roofing manufacturing facility in Norwood,
Massachusetts. The Norwood plant includes the roofing manufacturing facility,
a granule plant and an asphalt plant. The Company's quarry is located in
Wrentham, Massachusetts, and its closed private landfill is located in
Walpole, Massachusetts. The Company leases an industrial laminator and certain
other equipment which were fabricated for use in its roofing plant. The
laminator lease expires in 1998. The Company completed the construction of an
asphalt oxidizer plant at the Norwood premises in January 1995 to ensure a
continuous supply of asphalt. The Company also leases an asphalt storage tank
and terminal facilities in Providence, Rhode Island.
 
LEGAL PROCEEDINGS
 
  In 1992, a subsidiary of the company, Bird Atlantic Corporation ("BAC"),
formerly Atlantic Building Products Corporation, commenced an action against a
former vendor, alleging violation of an exclusive distributorship without
adequate and fair compensation to BAC. A jury trial was held in November 1995
in the Superior Court of Plymouth County, Massachusetts. The jury found in
favor of BAC and judgment was entered on January 26, 1996 in the principal
amount of approximately $1.8 million. The award, with interest accruing at 12%
per annum, is expected to be in excess of $3 million and will not be reported
as income until collected. Both defendant and BAC have appealed the judgment.
 
INSURANCE AND PRODUCT LIABILITY CLAIMS
 
  On June 1, 1993, Wausau commenced an action in the Superior Court for
Norfolk County, Massachusetts, against the Company seeking a declaratory
judgment that certain built-up roofing and fiber glass based shingle
 
                                      40

 
claims made against the Company were not covered by liability insurance
policies issued by Wausau. The Company asserts that the claims are covered and
has answered the complaint. A trial is expected in 1999. In the opinion of
management, the above matter will not have a material adverse effect on the
Company's financial position or results of operations.
 
  The Company is also exposed to a number of other asserted and unasserted
potential claims encountered in the normal course of business. In the opinion
of management, the resolution of such claims will not have a material adverse
effect on the Company's financial position or results of operations.
 
  The Company is a defendant in a number of suits alleging product defects,
the outcome of which management believes will not in the aggregate have a
material impact on the Company's financial position or results of operations.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders
of Bird Corporation
 
  We have audited the accompanying consolidated balance sheets of Bird
Corporation and its subsidiaries as of December 31, 1997 and 1996, and the
related consolidated statements of operations, of stockholders' equity and of
cash flows for each of the three years in the period ended December 31, 1997.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements
based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements audited by us present
fairly, in all material respects, the financial position of Bird Corporation
and its subsidiaries as of December 31, 1997 and 1996, and the results of
their operations and their cash flows for each of the three years in the
period ended December 31, 1997, in conformity with generally accepted
accounting principles.

                       BIRD CORPORATION AND SUBSIDIARIES
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. ACCOUNTING POLICIES
 
 Nature of Operations
 
  Bird Corporation is a manufacturer of asphalt roofing products. Currently,
asphalt shingles and roll roofing are produced at the Company's plant in
Norwood, Massachusetts for commercial and residential use. These products are
marketed in the northeastern United States through independent wholesalers and
building material retailers whose primary customers are roofing contractors.
 
 Basis of Consolidation
 
  The accompanying consolidated financial statements include the accounts of
Bird Corporation and its majority-owned subsidiaries (the "Company"). All
material intercompany activity has been eliminated from the financial
statements.
 
 Pervasiveness of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Concentration of Risk and Major Customers
 
  The Company is dependent upon the economy in the northeastern United States
and sells its products primarily to independent wholesalers and building
material retailers for resale primarily to roofing contractors. One customer
accounted for slightly more than 15% of the Company's gross sales during 1997
and 1996 and 10% in 1995.
 
  The principal raw materials used in the manufacture of asphalt roofing
products are fiberglass mat, asphalt saturants and coatings and crushed
granules. The Company's requirements for fiberglass mat are met primarily with
one vendor under an agreement which expires December 31, 1999 with an option
to extend for an additional two years. Fiberglass mat is also generally
available in adequate quantities from a number of outside suppliers. The
Company has a raw material processing agreement with a company whose President
is also a Director of Bird Corporation. The Company's purchases from this
related party amounted to $1,707,000 in 1997, $1,817,000 in 1996, and
$1,619,000 in 1995. Management believes that amounts paid were equivalent to
those that would be paid under an arm's length transaction. At December 31,
1997 and 1996 amounts due to this company totaled $115,000 and $268,000,
respectively.
 
 Revenue Recognition
 
  The Company recognizes revenue when products are shipped or services are
performed.
 
 Cash and Equivalents
 
  The Company considers all highly liquid instruments purchased with a
maturity of three months or less to be cash equivalents. On occasion the
Company invests its excess cash in a money market account that is subject to
minimal credit and market risk. There were no such investments at December 31,
1997.
 
 Inventories
 
  Inventories are valued at the lower of cost or market. Cost is determined
for a large portion of the inventories by the last-in, first-out (LIFO) method
computed using the dollar value method for natural business unit pools. The
cost of the remaining inventories is determined on a first-in, first-out
(FIFO) basis.

                       BIRD CORPORATION AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
 Property, Plant and Equipment
 
  Property, plant and equipment is stated at cost. Depreciation has been
provided in the financial statements primarily on the straight-line method at
rates, based on reasonable estimates of useful lives, which fall within the
following ranges for major asset classifications:
 

                                                               
   Land improvements............................................. 10 to 20 years
   Buildings..................................................... 20 to 25 years
   Machinery and equipment.......................................  5 to 13 years

 
  Depreciation expenses for continuing operations for 1997, 1996 and 1995
amounted to $2,741,000, $2,709,000 and $2,831,000, respectively. Maintenance,
repairs and minor renewals are charged to earnings in the year in which the
expense is incurred. Additions, improvements and major renewals are
capitalized. The cost of assets retired or sold, together with the related
accumulated depreciation, are removed from the accounts, and any gain or loss
on disposition is credited or charged to earnings.
 
 Retirement Plans
 
  The Company has a defined contribution plan covering substantially all
eligible non-union salaried and non-union hourly employees. Annual
contributions are made to the plan based on rates identified in the plan
agreement.
 
 Advertising
 
  Advertising costs are charged to operations when incurred. The Company did
not incur any costs associated with direct response advertising in 1997, 1996
and 1995, and there were no capitalized advertising costs at December 31, 1997
and 1996. Advertising expense for 1997, 1996 and 1995 was $443,000, $485,000,
and $503,000, respectively.
 
 Earnings (Loss) per Common Share
 
  In February 1997, the Financial Accounting Standard Board issued Statement
of Financial Accounting Standards No. 128, "Earnings per Share" ("SFAS 128").
This statement supercedes the pronouncement of Accounting Principles Board
("APB No. 15") and is effective with the Company's fiscal year ended December
31, 1997. The statement eliminates the calculation of primary earnings per
share and requires the disclosure of basic earnings per share and diluted
earnings per share (formerly referred to as fully dilutive earnings per
share), if applicable. Basic earnings (loss) per common share excludes
dilution and is determined after deducting the dividend requirements of the
preferred and preference shares and is based on the weighted average number of
common shares outstanding during each period. Diluted earnings (loss) per
common share gives effect to the reduction in earnings per share, if any,
which would result from potential common stock (the conversion of the $1.85
cumulative convertible preference stock and the inclusion of dilutive stock
options) during the period if the effect is dilutive. The Company has restated
all prior period earnings (loss) per share information in accordance with the
statement and has excluded potential common stock from the calculation of
diluted weighted average share amounts for the years 1997, 1996 and 1995 as
its inclusion would have been anti-dilutive.
 
 Environmental Matters
 
  The Company records a liability for environmental matters when it is
probable that a liability has been incurred and the amount of the liability
can be reasonably estimated based on the available evidence and site
assessments. If an amount is likely to fall within a range and no single
amount within that range can be determined to be a better estimate, the
minimum amount of the range is recorded. If there are other participants

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
and the liability is joint and several, the financial stability of the other
participants is considered in determining the Company's accrual. Costs of
future expenditures for environmental remediation obligations are not
discounted to their present value. In addition, the liability excludes claims
for recoveries from insurance companies and other third parties until such
claims for recoveries are probable of realization at which point they would be
classified separately as a receivable.
 
 Warranty Costs
 
  The Company warrants under certain circumstances that its building material
products meet certain manufacturing and material specifications. The warranty
policy is unique to each product, ranges from five to forty years, is
generally for the material cost and requires the owner to meet specific
criteria such as proof of purchase. The Company offers the original
manufacturer's warranty only as part of the original sale and at no additional
cost to the customer. In addition, for marketing considerations, the Company
makes elective settlements in response to customer complaints. The Company
records the liability for warranty claims and elective customer settlements
when it determines that a specific liability exists or a payment will be made.
 
 Stock Compensation
 
  The Company's employee stock option plans are accounted for in accordance
with Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued
to Employees". In 1996, the Company adopted the disclosure requirements of
Statement of Financial Accounting Standards No. 123 "Accounting for Stock-
Based Compensation".
 
2. INVENTORIES
 
  The percentages of inventories valued on the LIFO method was 98% at December
31, 1997 and 1996. It is not practical to separate LIFO inventories by raw
materials and finished goods components; however, the following table (in
thousands) presents these components on a current cost basis with the LIFO
reserve shown as a reduction.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  The Company's external financing needs were augmented by its ability to
borrow under the three year Loan and Security Agreement dated November 30,
1994 (and amended March 8, 1995) with Fleet Capital Corporation. It was
replaced on July 8, 1997, with a new three year $15,000,000 Revolving Credit
and Security Agreement ("Credit Agreement") with Fleet National Bank
("Fleet"). Up to $3 million of the revolving credit facility could be used for
letters of credit. At December 31, 1997, letters of credit totaled $805,000
compared to $1,401,000 as of December 31, 1996.
 
  Borrowings by Bird Incorporated under the Credit Agreement were guaranteed
by the Company and the Company's other subsidiaries and were secured by
accounts receivable and inventory. The revolving credit line availability was
determined with reference to a percentage of accounts receivable and
inventory. Under the Credit Agreement, the availability calculation did not
allow borrowings to the full extent of the revolving credit commitment due to
the seasonality of the building materials manufacturing business. As of
December 31, 1997, an aggregate of $5,864,000 was available to the Company
under the terms of the Credit Agreement of which $3,358,000 remained
available, net of current borrowings and letters of credit.
 
  Interest on the Credit Agreement accrued at the Fleet base rate less 1/2%
(as specified in such Credit Agreement) or the London Interbank Offering Rate
("LIBOR") plus 1 1/2% at the Company's election. The interest rates on
outstanding borrowings at December 31, 1997 were 8.25% on a $700,000, 7 day
LIBOR loan expiring January 5, 1998 and 7.46875% on a $1 million, 30 day LIBOR
loan expiring on January 28, 1998.
 
  The Credit Agreement contained certain financial and operating covenants and
placed limits on the Company's capital expenditures. As of December 31, 1997,
the Company was in default under Section 5.9 of the Credit Agreement as a
result of failing to achieve the minimum fixed charge coverage ratio for the
fourth quarter of 1997. As a result of the change of control on February 16,
1998 resulting from completion of the Tender Offer, the terms of the Credit
Agreement required repayment of indebtedness. On February 18, 1998, the
Company repaid all indebtedness with the exception of outstanding letters of
credit aggregating $805,000. Fleet will maintain its security interest in the
assets of the Company until revocation of the letters of credit occurs, which
is expected in the second quarter of 1998.
 
  The weighted average interest rates on short term borrowings at December 31,
1997 and December 31, 1996 were 7.56% and 8.25%, respectively. The fair value
of the Company's total debt approximated the carrying value at December 31,
1997 and 1996, respectively. The fair value is based on management's estimate
of current rates available to the Company for similar debt with the same
remaining maturity.

  Additionally, for federal income tax purposes, at December 31, 1997 the
Company had available for carryforward minimum tax credits with no expiration
aggregating $1,016,000. On February 16, 1998, a change in the Company's
ownership occurred as a result of the completion of the tender offer by BI
Expansion II Corp., a wholly owned subsidiary of CertainTeed Corporation (see
Note 13). Consequently, there will be an annual limitation on the amount of
the carryforwards, including certain unrealized built-in losses, which can be
utilized for regular and alternative minimum tax purposes.
 
  At December 31, 1997, the Company's net deferred tax asset is approximately
$21 million less a valuation reserve of $17 million which was determined based
upon the Company's review of all available evidence including projections of
future taxable income. The Company expects to be profitable and with other tax
planning strategies expects to generate future taxable income. Realization of
the $4,066,000 net deferred tax asset is dependent on generating sufficient
taxable income prior to expiration of the loss carryforwards. Although
realization is not assured, management believes that it is more likely than
not that the net deferred tax asset will be realized.
 
5. STOCKHOLDERS' EQUITY
 
  The $1.85 cumulative convertible preference stock is redeemable, in whole or
in part, at the option of the Company, at a redemption price of $20.00 per
share. The convertible preference stock has a liquidation value of $20.00 per
share and is convertible at the option of the holder into common stock of the
Company at a conversion price of $22.25 per share, subject to adjustment in
certain events. Dividends are cumulative from the date of issue and are
payable quarterly. There are five preference dividends in arrears at December
31, 1997. The Company has the option to redeem the convertible preference
stock. The Company's 5% cumulative preferred stock ranks senior to the
convertible preference stock as to dividends and upon liquidation.
 
  On June 18, 1992, the Company announced that its Board of Directors
authorized it to buy back, on the open market or in privately negotiated
transactions, up to 400,000 of its outstanding shares of common stock at
prices available from time to time that the Company deems attractive. Since
this announcement, the Company has repurchased 97,619 shares.
 
  The Company is prohibited from purchasing its common stock as long as
dividends on the convertible preference stock are in arrears. Under the 1992
Stock Option Plan described in Note 6, 931,325 shares of common stock are
reserved for issuance upon exercise of options and stock appreciation rights
at December 31, 1997.
 
  Restrictions on the payment of dividends on common and preference stock in
arrears are imposed by the terms of the Credit Agreement dated July 8, 1997.
Payment of dividends on currently accrued preferred and preference stock are
permitted under the Credit Agreement. As of December 31, 1997, all dividends
on the preferred stock have been declared and paid in full. Dividends in
arrears on the preference stock in the aggregate amount of $1,506,000 for the
four quarterly periods ended February 15, 1995 and $377,000 for the quarterly
period ended May 15, 1996 require Fleet approval prior to distribution.
Dividends on the preference stock must be paid in full before any dividends
could be declared and paid on the common stock. The quarterly dividends on the
preference stock due February 15, May 15, August 15, and November 15, 1997 in
the aggregate amount of $1,506,000 have, with the consent of Fleet, been
declared and paid in full.
 
  On February 16, 1998 BI Expansion II Corp., a wholly-owned subsidiary of
CertainTeed Corporation, an indirect wholly-owned subsidiary of Compagnie de
Saint-Gobain (Paris, France), accepted for payment pursuant to a cash tender
offer 3,991,022 shares of the common stock, $1 par value per share, of the
Company or approximately 96% of the common stock outstanding, and 772,735
shares of the $1.85 Cumulative Convertible Preference Stock, $1 par value per
share, of the Company, or approximately 95% of the Preference Stock

outstanding, at a price of $5.50 per share of Common Stock and $20 per share
of Preference Stock, without any adjustment for dividends accrued and unpaid
through the date of the expiration of the Tender Offer (February 13, 1998);
such dividends amounted to $1,883,000 on December 31, 1997 and $2,260,000 on
February 16, 1998 which included the undeclared dividend of $377,000 due on
February 15, 1998 (see Note 13).
 
6. EMPLOYEE BENEFIT PLANS
 
 Retirement Plans
 
  The Company's "Bird Employees' Savings and Profit Sharing Plan" provides for
a defined base contribution and profit sharing and savings contributions.
 
 Defined Base Contribution
 
  The Company contributes annually 2% of plan participants' basic
compensation. Vesting accrues at 20% per year of service. Contributions for
continuing operations for the years ended December 31, 1997, 1996, and 1995
amounted to $68,000, $64,000, and $72,000, respectively.
 
 Profit Sharing Contribution
 
  Profit sharing contributions are made annually, if earned, based upon
certain defined levels of return on equity by the Company and its business
units. The distribution of the contribution to the plan's participants is
based upon annual basic compensation. No profit sharing contributions were
earned for 1997, 1996 or 1995.
 
 Savings Contribution
 
  The Company's savings plan provides that eligible employees may contribute
to the plan any whole percentage of their basic compensation varying from 2 to
15%. The Company may make discretionary matching contributions not exceeding
6% of the participant's basic compensation during the plan year. Such matching
Company contributions are invested in shares of the Company's common stock.
The Company's contributions for continuing operations for the years ended
December 31, 1997, 1996, and 1995 amounted to $93,000, $91,000, and $124,000,
respectively.
 
 Post Retirement Benefits
 
  Certain health care and life insurance benefits were provided for
substantially all of the Company's retired employees, except those covered
under union plans. Benefits are provided by the payment of premiums for life
insurance benefits and the elective reimbursement for eligible employees of a
portion of their health care premiums. On October 30, 1997, all current and
future participants in the health care plan were notified that the Company
would no longer offer health care insurance benefits under the plan after
December 31, 1997. The Company's cost for the years 1997, 1996, and 1995
amounted to $64,000, $71,000, and $66,000, respectively. Life insurance
benefits continue to be provided to eligible retired employees. The effect of
curtailing health care benefits did not have a material effect on the results
of operations in 1997.
 
  Employee Incentive Plans
 
  Under the 1982 Stock Option Plan, as amended, options to purchase up to
900,000 shares of the Company's common stock may be granted to officers,
directors and key employees upon terms and conditions determined by a
committee of the Board of Directors which administers the plan. In 1993, the
Company adopted a new stock option plan which allows the issuance of up to
450,000 stock options in addition to the unissued shares approved for issuance
under the 1982 plan. The new plan will expire in 2002 and no further options
will be

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
granted under the former plan. A Non-Employee Directors' Stock Option Plan was
also adopted in 1993 which will automatically provide grants of options to
each non-employee director serving on the Board of Directors at the time of
such grant. Each annual grant will cover 2,500 shares of common stock and any
recipient may not receive option grants exceeding a total of 30,000 shares. An
aggregate of 100,000 shares of common stock are available for grants under the
Non-Employee Directors' Stock Option Plan.
 
  Options granted by the committee may be designated as either incentive stock
options, as defined under the current tax laws, or non-qualified options. The
committee may also grant stock appreciation rights, either singly or in tandem
with stock options. A right entitles the holder to benefit from market
appreciation in the Company's common stock subject to the right between the
date of the grant and the date of exercise without any payment on the part of
the holder. Upon exercise of a right, the holder surrenders the option and
receives an amount of common stock (or, at the election of the committee,
cash) equal in value to the amount of such appreciation.
 
  The exercise price of options specified by the committee must be at least
100% of the fair market value of the Company's common stock as of the date of
grant. All options and rights granted become exercisable at the rate of 20 to
25% per year, on a cumulative basis, beginning with the first anniversary of
the date of grant for options granted under the Stock Option Plan and in full
one year after grant for option granted under the Non-Employee Directors'
Stock Option Plan. In case of termination of employment, options and grants
vested, but not yet exercised, are subject to forfeiture under the Stock
Option Plan and are exercisable up to 90 days after termination for the Non-
Employee Directors' Stock Option Plan.
 
  In tandem with the stock options there are 8,000 stock appreciation rights
at December 31, 1997.
 
  Transactions involving the Stock Option Plan are summarized as follows for
the years ended December 31, 1997 and 1996:

value of options granted in years beginning after December 31, 1994 at grant
date as prescribed by Statement of Financial Accounting Standard No. 123
"Accounting for Stock-Based Compensation," issued in October 1995, net income

  Because the determination of the fair value of all options granted includes
vesting periods over several years and additional option grants are expected
to be made each year, the above pro forma disclosures are not representative
of pro forma effects of reported net income for future periods.
 
7. SALE OF BUSINESSES
 
  The Company records income and expenses associated with former business
activities on the Consolidated Statement of Operations under the caption "Gain
on Disposal of Businesses". In April 1996, the Company favorably settled a
legal dispute related to the cancellation of a Supply and Sales Representative
Agreement with a former business partner. The settlement agreement calls for
Bird to receive total payments of $410,000 over a period of two years, for
cancellation of the Sale Representative and Supply Agreements, and termination
of the partnership. In July 1996, the Company received an aggregate of
$535,000 in cash for the settlement of three legal disputes relating to
insurance coverage. These legal disputes related to the Company's former vinyl
and roofing businesses.
 
  In December 1996, the Company was reimbursed $123,000 for costs associated
with the remediation of an underground storage tank system at its former
distribution center located in Arizona.
 
  On March 8, 1995, the Company sold substantially all of the assets of its
vinyl business to Jannock, Inc. for $47.5 million in cash subject to certain
downward adjustments which totaled $4,962,000. Net of adjustments, the gain on
the sale of the vinyl business totaled $20,579,000. Sales of $6,365,000 were
recorded for the vinyl business in 1995 through the date of the sale.
 
  On June 2, 1995 the Company sold all of the outstanding capital stock of
Bird-Kensington Holding Corp., which owned the Company's interest in
Kensington Partners, to Jannock, Inc. The purchase price consisted of
 
                                     F-15

 
                       BIRD CORPORATION AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
cash in the gross amount of $2,780,000 and the assumption of certain
liabilities related to the Kensington window business. The sale resulted in a
loss of $1,959,000. Sales of $4,265,000 were recorded for this business for
the period March 1, 1995 through June 2, 1995.
 
  The Company recorded other expenses related to former business activities of
$149,000, and $1,050,000 for the years 1996, and 1995, respectively. These
charges against earnings include warranty claims and other costs directly
related to former business activities. Expenses incurred in 1995 also included
$1.5 million in provisions relating to employee benefit plans and product
liability claims associated with former roofing operations which were offset
by a $602,000 crude oil refund from the Department of Energy.
 
8. OTHER EXPENSE, NET
 
  Other income in 1997 related to proceeds on company owned life insurance.
Other expenses in 1996 were primarily due to the $806,000 of costs associated
with a terminated merger agreement.
 
9. DISCONTINUED OPERATIONS
 
 Environmental Businesses
 
  In 1994, the Company agreed to cause the sale of its 80% interest in its
environmental business, Bird Environmental Gulf Coast, Inc. ("BEGCI") to the
minority shareholders thereof, subject to financing, resulting in the complete
withdrawal from the environmental business. However, during 1995, the minority
partner became unable to finance the purchase of the facility and efforts to
attract another purchaser were unsuccessful. In July 1995, the Company's Board
of Directors suspended further funding of the facility. As a result of this
action, during the second quarter of 1995, the Company's remaining investment
of $8.6 million was written off and a $3 million reserve was established for
additional expenses associated with the closure of the facility. On November
29, 1995, the Company caused the sale of all of the outstanding capital stock
of BEGCI to GTS Duratek, Inc. for a purchase price of $1.00. Net sales
relating to this business amounted to $2,848,000 for 1995. During the fourth
quarter of 1997, the Company recorded income from discontinued operations of
approximately $575,000 resulting from the reversal of a contingency reserve
established at the time of the sale of BEGCI. The contingency period expired
on December 1, 1997.
 
10. ACQUISITIONS
 
  On July 1, 1992 the Company entered into a 50% joint venture with Kensington
Manufacturing Company to manufacture vinyl replacement windows through
Kensington Partners ("Kensington"). On February 28, 1995, the Company's
ownership in the joint venture was permanently fixed at 90%, resulting in a
change in financial reporting from the equity method to consolidation
beginning March 1, 1995 through June 2, 1995 when the operation was sold (see
Note 7). For the two month period ended February 20, 1995, Kensington reported
net sales of $1,774,000 and a net loss of $413,000.
 
11. COMMITMENTS AND CONTINGENCIES
 
 Lease Commitments
 
  The Company leases certain manufacturing, administrative, warehousing,
transportation equipment and other facilities. The leases generally provide
that the Company pay the taxes, insurance and maintenance expenses related to
the leased assets.

 Litigation
 
  The Company monitors its compliance with environmental regulations on an
ongoing basis. The Company's general counsel receives environmental site
assessments from the operating managers responsible for site environmental
compliance. Appropriate action is undertaken where needed. When environmental
claims are asserted against the Company, the claims are evaluated by the
Company's general counsel and operating management in conjunction with
external legal counsel and environmental engineers as necessary, and action is
taken with respect to all known sites, as appropriate. The Company is
currently engaged in proceedings relating to or has received notice of the
following environmental matters:
 
  On June 21, 1994, the Arizona Department of Environmental Quality ("ADEQ")
issued a notice of violation ("NV") to Southwest Roofing Supply, a previously
owned division of the Company ("Southwest"), which directed Southwest to
conduct a site investigation of property formerly leased by Southwest. The
consent order between the ADEQ and the Company was issued on September 23,
1994. Pursuant to the order, the Company agreed to submit a work plan with a
view to remediating the soil and groundwater that may have been contaminated
by leaks from an underground storage tank previously removed by the Company.
On December 23, 1996, the consent order was satisfactorily closed between the
Arizona State Assurance Fund and the Company; however, the remediation work
must still be completed. The Company's management believes that the net
remediation cost to the Company will be approximately $150,000. As of December
31, 1997, the Company had a reserve of $150,000 for the estimated cost of
clean-up. The Company anticipates that $250,000 will be reimbursed to the
Company by the Arizona State Assurance Fund in accordance with Arizona law and
regulation.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  In 1986, the Company, along with numerous other companies, was named by the
EPA and other governmental agencies responsible for regulation of the
environment as a Potentially Responsible Person ("PRP") pursuant to the
Comprehensive Environmental Response, Compensation and Liability Act, as
amended, 42 U.S.C. Paragraph 9601, et seq. ("CERCLA") in connection with
hazardous substances at a site known as the Fulton Terminal Superfund site
located in Fulton, Oswego County, New York. On September 28, 1990, the Company
and a number of other PRPs reached a negotiated settlement with the EPA
pursuant to which the settling PRPs agreed to pay the costs of certain
expenses in connection with the proceedings and to pay certain other expenses,
including the costs and expenses of administering a trust fund to be
established by the settling PRPs. The settlement agreement is embodied in a
consent decree lodged with the United States District Court for the Western
District of New York and fixed the Company's proportionate share of the total
expenses. The soil has been cleaned-up and the groundwater is now being
treated. The remaining cost to the Company of the remedial work and other
expenses covered by the settlement agreement is estimated to be approximately
$200,000 payable over the next three years. At December 31, 1997, the Company
had a reserve of $200,000 to cover the estimated cost of the Company's
remaining proportionate share (i.e., 17%) of the cost to clean-up the
groundwater. Under a cost-sharing arrangement set forth in a consent decree
with the EPA, the other PRPs have agreed to incur 83% of the aggregate cost of
remediation of this site. Based on information currently available to the
Company, management believes that it is probable that the major responsible
parties will fully pay the cost apportioned to them. Management believes that,
based on its financial position and the estimated accrual recorded, the
remediation expense with respect to this site is not likely to have a material
adverse effect on the consolidated financial position or results of operations
of the Company.
 
  The Company has owned and operated a sanitary landfill since the late 1960's
used exclusively by the Company's roofing plant for the disposal of its own
manufacturing process waste, primarily asphalt roofing materials. No hazardous
or other specially regulated wastes have been disposed of at this site. As a
result of a 1995 regulatory decision by the Massachusetts Department of
Environmental Protection ("D.E.P.") to disallow the continued operation of all
unlined landfills, the Company chose not to seek to renew its operating permit
at the state or local level which expired at the end of August 1997. To
continue to operate the landfill would be of no financial benefit over the
existing outside disposal alternatives, given the new regulatory requirements
and the minimal quantities of waste being disposed of presently. Therefore, as
a result of this decision, the Company has begun negotiating a landfill
closure plan with the D.E.P. which may commence construction in 1998 and be
completed in 1999. As of December 31, 1997, the Company had a reserve of
approximately $800,000 to cover the estimated cost to close the landfill.
Management believes that the closure expense with respect to this site will
not have a material adverse effect on the results of operations or financial
condition of the Company.
 
  The Company has been named as a PRP with respect to certain other sites
which are being investigated by federal or state agencies responsible for
regulation of the environment. As a consequence of its status as a PRP, the
Company may be jointly and severally liable for all of the potential monetary
sanctions and remediation costs applicable to each site. In assessing the
potential liability of the Company at each site, management has considered,
among other things, the aggregate potential clean-up costs of each site; the
apparent involvement of the Company at each site and its prospective share of
the remediation costs attributable thereto; the number of PRPs identified with
respect to each site and their financial ability to contribute their
proportionate shares of the remediation costs for such site; the availability
of insurance coverage for the Company's involvement at each site and the
likelihood that such coverage may be contested; and whether and to what extent
potential sources of contribution from other PRPs or indemnification by
insurance companies constitute reliable sources of recovery for the Company.
Similar consideration has been given in determining the exposure and potential
liability of the Company in connection with other significant legal
proceedings to which the Company is a party. On the basis of such
consideration, management has determined that such environmental matters will
not have a material adverse effect on the Company's financial position or
results of operations.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  Since 1981 Bird has been named as a defendant in approximately 650 product
liability cases throughout the United States by persons claiming to have
suffered asbestos-related diseases as a result of alleged exposure to asbestos
used in products manufactured and sold by Bird. Approximately 150 of these
cases are currently pending and costs of approximately $2 million in the
aggregate have been incurred in the defense of these claims since 1981.
Employers Insurance of Wausau ("Wausau") has accepted the defense of these
cases under an agreement for sharing of the costs of defense, settlements and
judgments, if any. At December 31, 1997, the Company has a reserve of $950,000
to cover the estimated cost of these claims. In light of the nature and merits
of the claims alleged, in the opinion of management, the resolution of these
remaining claims will not have a material adverse effect on the results of
operations or financial condition of the Company.
 
  In 1992, a subsidiary of the Company, Bird Atlantic Corporation ("BAC")
formerly Atlantic Building Products Corporation, commenced an action against a
former vendor, alleging violation of an exclusive distributorship without
adequate and fair compensation to BAC. A jury trial was held in November 1995
in the Superior Court of Plymouth County, Massachusetts. The jury found in
favor of BAC and judgement was entered on January 26, 1996 in the principal
amount of approximately $1.8 million. The award, with interest accruing at 12%
per annum, is expected to be in excess of $3 million and will not be reported
as income until collected. The defendant and BAC have appealed the judgement.
 
  On April 16, 1996, a class action suit was filed in the Superior Court of
the Commonwealth of Massachusetts against Bird Incorporated, a wholly owned
subsidiary of the Company. The complaint alleges that Bird Incorporated has
knowingly manufactured, distributed and falsely advertised defectively
designed fiber glass based roofing shingles. The complaint sets forth claims
of fraud, negligent misrepresentation, negligence and breach of express and
implied warranty. The Company is currently in the process of defending against
the complaint. The Company has tendered the defense of the action to several
insurance carriers which have assumed its defense. In the opinion of
management, the above matter will not have a material adverse effect on the
Company's financial position or results of operations.
 
 Warranty Obligations
 
  The Company warrants under certain circumstances that its Housing Group's
products meet certain manufacturing and material specifications. In addition,
for marketing considerations, the Company makes elective settlements in
response to customer complaints. The Company records the liability for
warranty claims and elective customer settlements when it determines that a
specific liability exists or a payment will be made. During 1997, 1996 and
1995, the Company recorded (exclusive of those claims related to former
roofing operations) approximately $1,395,000, $2,155,000, and $2,262,000,
respectively, in warranty expenses and elective customer settlements. Based
upon analyses performed by the Company's management, a reasonably possible
range of potential liability from unasserted warranty obligations for all
products sold prior to December 31, 1997 is estimated to be between $3.5
million and $17.5 million. However, the Company has not recorded any liability
for these future unasserted claims or complaints because management has
concluded, based on such analyses, that no particular estimate within this
range is probable.

12. EARNINGS (LOSS) PER SHARE
 
  Basic earnings (loss) per share are computed by dividing earnings (loss)
available to common stockholders by the weighted average number of common
shares outstanding during the period. Diluted earnings per share reflect per
share amounts that would have resulted if dilutive potential common stock had
been converted to common stock. Diluted loss per share amounts exclude
potential common stock as its inclusion would be anti-dilutive.

                       BIRD CORPORATION AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  The Company has 814,300 shares of $1.85 cumulative convertible preference
stock outstanding; convertible into 731,955 shares of common stock. The
preference stock was not included in the 1996 computation of dilutive earnings
per share because the effect of the conversion would be anti-dilutive.
 
13. SUBSEQUENT EVENT--ACQUISITION BY CERTAINTEED CORPORATION
 
  On February 16, 1998 BI Expansion II Corp. ("Acquisition Sub"), a wholly-
owned subsidiary of CertainTeed Corporation ("CertainTeed"), an indirect
wholly-owned subsidiary of Compagnie de Saint-Gobain (Paris, France), accepted
for payment pursuant to a cash tender offer (the "Tender Offer") 3,991,022
shares of the common stock, $1 par value per share, of the Company (the
"Common Stock"), or approximately 96% of the Common Stock outstanding, and
772,735 shares of the $1.85 Cumulative Convertible Preference Stock, $1 par
value per share, of the Company (the "Preference Stock"), or approximately 95%
of the Preference Stock outstanding, at a price of $5.50 per share of Common
Stock and $20 per share of Preference Stock, without any adjustment for
dividends accrued and unpaid through the date of the expiration of the Tender
Offer (February 13, 1998).
 
  As a result of the completion of the Tender Offer, CertainTeed owns, through
Acquisition Sub, all but 170,354 shares of the outstanding shares of Common
Stock and all but 41,565 shares of the outstanding shares of Preference Stock.
The Common Stock no longer meets the continuing inclusion requirements for
Nasdaq National Market securities, and there is little or no market for either
the Common Stock or the Preference Stock. Accordingly, the Company withdrew
from Nasdaq Stock Market listing the Common Stock and the Preference Stock,
effective at the close of business on March 3, 1998.
 
  The Tender Offer was the first step in the acquisition of the Company by
CertainTeed contemplated by an Agreement and Plan of Merger dated as of
January 12, 1998 (the "Merger Agreement") between the Company, CertainTeed and
Acquisition Sub. The second step in the transaction will be the merger (the
"Merger") of Acquisition Sub with and into the Company, with the Company
surviving the Merger as a wholly-owned subsidiary of CertainTeed. Upon the
effectiveness of the Merger, each outstanding share of Common Stock (other
than shares held by stockholders who perfect their appraisal rights under
Massachusetts law, shares held in the Company's treasury and shares held
directly by Acquisition Sub or CertainTeed) will be converted into the right
to receive $5.50 in cash, and each share of Preference Stock (other than
shares held by stockholders who perfect their appraisal rights under
Massachusetts law, shares held in the Company's treasury and shares held
directly by Acquisition Sub or CertainTeed) will be converted into the right
to receive $20 in cash, which amount will not be adjusted for any dividends
accrued and unpaid through the date of the consummation of the Merger.
Outstanding options to acquire shares of Common Stock with an exercise price
of less than $5.50 per share will be converted into the right to receive a
cash payment equal to the number of shares purchasable upon exercise of the
option multiplied by the difference between $5.50 and the exercise price. The
Company's outstanding 5% Cumulative Preferred Stock, par value $100 per share
("5% Stock"), will remain issued and outstanding upon the effectiveness of the
Merger and will be called for redemption and retirement as soon as is
practicable thereafter at a price equal to $110, plus all accrued and unpaid
dividends thereon as of the date of redemption and retirement. The total
consideration for CertainTeed's acquisition of the Company is approximately
$40 million, including payment for the Common Stock and the Preference Stock
pursuant to the Tender Offer and Merger and for the 5% Stock upon redemption,
but excluding outstanding indebtedness of the Company.
 
  The closing of the Merger is anticipated during the second quarter of 1998,
following distribution of an information statement to the Company's
stockholders and approval of the Merger Agreement at a special meeting of
stockholders. The consummation of the Merger is subject to approval of the
Merger Agreement by at least 66 2/3% of the outstanding shares of Common Stock
and at least 66 2/3% of the outstanding shares of Preference Stock. As a
result of the completion of the Tender Offer, Acquisition Sub has sufficient
voting power to effect the Merger without the vote of any other stockholder of
the Company.

  This AGREEMENT AND PLAN OF MERGER dated as of January 12, 1998, is entered
  into by and among CERTAINTEED CORPORATION, a Delaware corporation
  ("Parent"), BI EXPANSION II CORP., a Massachusetts corporation
  ("Acquisition Sub"), and BIRD CORPORATION, a Massachusetts corporation (the
  "Company").
 
  WHEREAS the respective Boards of Directors of Parent, Acquisition Sub and
the Company have approved the making by Acquisition Sub of a tender offer from
time to time (the "Offer") to purchase all outstanding shares of Company
Common Stock (as defined below) at a price per share equal to the Total Merger
Consideration (as defined below) (the "Common Stock Offer Price") and all
outstanding shares of Preference Stock (as defined below) at a price per share
equal to $20, which amount shall not be adjusted for any accrued and unpaid
dividends thereon as of, or any dividends paid prior to, the date of the
expiration of the Offer (the "Preference Stock Offer Price") along with the
merger of Acquisition Sub with and into the Company (the "Merger"), upon the
terms and subject to the conditions set forth herein, as a result of which the
Company will become a wholly owned subsidiary of Parent and the stockholders
of the Company (other than stockholders who perfect appraisal rights) will be
entitled to receive the consideration provided in this Agreement.
 
NOW, THEREFORE, in consideration of the mutual benefits to be derived from
this Agreement and of the representations, warranties, covenants and
agreements hereinafter contained, Parent, Acquisition Sub and the Company
agree as follows:
 
                                   ARTICLE I
 
                           THE OFFER AND THE MERGER
 
  Section 1.01. The Offer. (a) Subject to the provisions of this Agreement, as
promptly as practicable, but in no event later than five business days after
the public announcement of the Offer, Acquisition Sub shall commence the
Offer. The obligation of Acquisition Sub to commence the Offer and accept for
payment, and pay for, any shares of Company Common Stock or Preference Stock
tendered pursuant to the Offer shall be subject to the conditions set forth in
Exhibit A (any of which may be waived in whole or in part by Acquisition Sub
in its sole discretion) and to the terms and conditions of this Agreement.
Acquisition Sub expressly reserves the right to modify the terms of the Offer,
except that, without the consent of the Company, Acquisition Sub shall not (i)
reduce the number of shares of Company Common Stock or Preference Stock to be
purchased in the Offer, (ii) reduce the Common Stock Offer Price or the
Preference Stock Offer Price, (iii) modify or add to the conditions set forth
in Exhibit A, (iv) except as provided in the next sentence, extend the Offer,
(v) change the form of consideration payable in the Offer or (vi) amend any
other term of the Offer in a manner adverse in any material respect to the
holders of Company Common Stock or Preference Stock. Notwithstanding the
foregoing, Acquisition Sub may, without the consent of the Company, (i) extend
the Offer beyond any scheduled expiration date (the initial scheduled
expiration date being 20 business days following commencement of the Offer)
for a period not to exceed 20 business days, if at any scheduled expiration
date of the Offer, any of the conditions to Acquisition Sub's obligation to
accept for payment, and pay for, shares of Company Common Stock or Preference
Stock shall not be satisfied or waived, until such time as such conditions are
satisfied or waived, (ii) extend the Offer for any period required by any
rule, regulation, interpretation or position of the Securities and Exchange
Commission (the "SEC") or the staff thereof applicable to the Offer and (iii)
terminate the Offer without prejudice to any of its and Parent's rights under
this Agreement, including to proceed with the Merger in accordance with, and
subject to the terms and conditions of, this Agreement. Subject to the terms
and conditions of the Offer and this Agreement, Acquisition Sub shall accept
for payment, and pay for, all shares of Company Common Stock and Preference
Stock validly tendered and not withdrawn pursuant to the Offer that
Acquisition Sub becomes obligated to accept for payment, and pay for, pursuant
to the Offer as soon as practicable after expiration of the Offer, subject to
compliance with Rule 14e-1(c) under the Exchange Act (as defined below).
 
  (b) On the date of commencement of the Offer, Parent and Acquisition Sub
shall file with the SEC a Tender Offer Statement on Schedule 14D-1 with
respect to the Offer, which shall contain an offer to purchase and a
 
                                       1

 
related letter of transmittal and summary advertisement (such Schedule 14D-1
and the documents included therein pursuant to which the Offer will be made,
together with any supplements or amendments thereto, the "Offer Documents").
Parent and Acquisition Sub agree that the Offer Documents shall comply as to
form in all material respects with the Securities Exchange Act of 1934, as
amended, and the rules and regulations promulgated thereunder (the "Exchange
Act") and, on the date first published, sent or given to the Company's
stockholders, shall not contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under
which they were made, not misleading, except that no representation is made by
Parent or Acquisition Sub with respect to information regarding the Company or
its subsidiaries or provided by the Company for inclusion or incorporation by
reference in the Offer Documents. Each of Parent, Acquisition Sub and the
Company agrees promptly to correct any information provided by it for use in
the Offer Documents if and to the extent that such information shall have
become false or misleading in any material respect, and each of Parent and
Acquisition Sub further agrees to take all steps necessary to amend or
supplement the Offer Documents and to cause the Offer Documents as so amended
or supplemented to be filed with the SEC and to be disseminated to the
Company's stockholders, in each case as and to the extent required by
applicable Federal securities laws. The Company and its counsel shall be given
a reasonable opportunity to review and comment upon the Offer Documents and
all amendments and supplements thereto prior to their filing with the SEC or
dissemination to stockholders of the Company. Parent and Acquisition Sub agree
to provide the Company and its counsel any comments or requests for additional
information Parent, Acquisition Sub or their counsel may receive from the SEC
or its staff with respect to the Offer Documents promptly after the receipt of
such comments and shall provide the Company and its counsel an opportunity to
participate, including by way of discussion with the SEC or its staff, in the
response of Parent and/or Acquisition Sub to such comments.
 
  (c) Parent shall provide or cause to be provided to Acquisition Sub on a
timely basis the funds necessary to accept for payment, and pay for, any
shares of Company Common Stock and Preference Stock that Acquisition Sub
accepts for payment, and becomes obligated to pay for, pursuant to the Offer.
 
  Section 1.02. Company Actions. (a) The Company hereby approves of and
consents to the Offer and represents that the Board of Directors of the
Company, at a meeting duly called and held, adopted resolutions approving this
Agreement, the Offer, the Merger and the transactions contemplated hereby,

best interests of, the Company's stockholders and recommending that the
Company's stockholders approve and adopt this Agreement, accept the Offer and
tender their shares pursuant to the Offer and/or vote their shares of Company
Common Stock and Preference Stock in favor of the Merger.
 
  (b) Not later than the date the Offer Documents are filed with the SEC, the
Company shall file with the SEC a Solicitation/Recommendation Statement on
Schedule 14D-9 (which shall include the information required by Section 14(f)
of the Exchange Act and Rule l4f-1 promulgated thereunder with respect to the
persons to be named directors of the Company pursuant to Section 5.21) with
respect to the Offer (such Schedule 14D-9, as amended from time to time, the
"Schedule 14D-9") containing the recommendation described in Section 1.02(a)
and shall mail the Schedule 14D-9 to the stockholders of the Company. The
Schedule 14D-9 shall comply as to form in all material respects with the
Exchange Act and the rules and regulations promulgated thereunder and, on the
date filed with the SEC and on the date first published, sent or given to the
Company's stockholders, shall not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, except that no
representation is made by the Company with respect to information provided by
Parent or Acquisition Sub for inclusion or incorporation by reference in the
Schedule 14D-9. Each of the Company, Parent and Acquisition 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.

any comments or requests for additional information 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 and shall provide Parent and its
counsel an opportunity to participate, including by way of discussions with
the SEC or its staff, in the response of the Company to such comments.

Preferred Stock, par value $100 per share (the "5% Stock"), actually issued
and outstanding at the Effective Date, shall remain issued and outstanding
after the Merger and shall be called for redemption and retirement as soon as
practicable following the Merger (except for Dissenting Shares, as defined in
Section 1.12), in accordance with the terms of Section 5.16(a), at a price
equal to $110, plus all accrued and unpaid dividends thereon as of the date of
redemption and retirement (the "5% Stock Consideration"), in accordance with
the terms of the 5% Stock.
 
  (c) $1.85 Cumulative Convertible Preference Stock. (i) Each share of the
Company's $1.85 Cumulative Convertible Preference Stock, par value $1 per
share (the "Preference Stock"), actually issued and outstanding at the
Effective Date (except for Dissenting Shares, as defined in Section 1.12)
shall, by virtue of the Merger and without any action on the part of the
holder thereof, be converted into the right to receive $20, which amount shall

  (ii) Each share of Preference Stock held directly by Parent or Acquisition

outstanding shares of Common Stock, par value $1 per share, of Acquisition Sub
(the "Acquisition Sub Common Stock") at the Effective Date shall, by virtue of
the Merger and without any action on the part of the holder thereof, be
converted into and exchangeable for, in the aggregate, 100 fully paid and
nonassessable shares of Common Stock, par value $1 per share, of the Surviving
Corporation (the "Surviving Corporation Common Stock"), which shall constitute
all the issued and outstanding shares of Surviving Corporation Common Stock.
From and after the Effective Date, each outstanding certificate theretofore

to the contrary, shares of Company Common Stock, 5% Stock and Preference Stock
issued and outstanding on the Effective Date which are held of record by

                                       4

 
and who shall have properly exercised rights to demand payment of the fair
value of such shares in accordance with Sections 86 through 98, inclusive, of
the MBCL ("Dissenting Shares") shall not be converted into the right to
receive the consideration specified in Section 1.10(a), 1.10(b), or 1.10(c),
respectively, but the holders thereof instead shall be entitled to payment of
the fair value of such shares in accordance with the provisions of Sections 86
to 92, inclusive, of the MBCL (the "Dissenting Consideration"); provided,
however, that (i) if such a holder fails to file a notice of election to
dissent in accordance with Section 86 of the MBCL or, after filing such notice
of election, subsequently delivers an effective written withdrawal of such
notice or fails to establish his entitlement to appraisal rights as provided
in Sections 87 through 98, inclusive, of the MBCL, if he or she be so
required, or (ii) if a court shall determine that such holder is not entitled
to receive payment for his shares or such holder shall otherwise lose his or
her appraisal rights, then in either of such cases, each share of Company
Common Stock, 5% Stock or Preference Stock, respectively, held of record by
such holder or holders shall automatically be converted into and represent
only the right to receive the Total Merger Consideration, the 5% Stock
Consideration or the Preference Stock Consideration, respectively, upon the
surrender of the certificate or certificates representing such Dissenting
Shares. The Company shall give Parent prompt notice of any demands received by
the Company for payment of the fair value of such shares, and Parent shall
have the right to participate in all the negotiations and proceedings with
respect to such demands. The Company shall not, except with the prior written
consent of Parent, make any payment (except to the extent that any such
payment is made pursuant to a court order) with respect to, or settle or offer
to settle, any such demands.
 
  Section 1.13. Surrender of Shares. (a) At and after the Effective Date,
Parent shall make available on a timely basis, by transferring to ChaseMellon
Shareholder Services, Inc. (the "Paying Agent") for the benefit of former
stockholders of the Company, such funds as and when necessary to make the
payments provided for in Section 1.10 herein with respect to the outstanding
shares of Company Common Stock and Preference Stock. The Paying Agent shall
agree to hold such funds in trust for the benefit of the former stockholders
of the Company and deliver such funds in accordance with the terms hereof and
the terms of a Paying Agency Agreement to be entered into by and between the
Paying Agent and Parent.
 
  (b) Prior to or at the Effective Date, the Paying Agent shall mail or cause
to be mailed to each record holder of an outstanding certificate or
certificates which, immediately prior to the Effective Date, represented
shares of Company Common Stock or Preference Stock (the "Certificates"), a
form 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) (the "Transmittal
Letter") and instructions for use in effecting the surrender of the
Certificates for payment therefor. Upon surrender to the Paying Agent of a
Certificate, together with such Transmittal Letter duly executed, the holder
of such Certificate shall be entitled to receive in exchange for each share of
Company Common Stock or Preference Stock represented by such Certificate, the
Total Merger Consideration or Preference Stock Consideration, respectively,
and such Certificate shall forthwith be canceled upon receipt by the holder of
such Certificate of the Total Merger Consideration or Preference Stock
Consideration, respectively. No interest will be paid or accrued on the Total
Merger Consideration or Preference Stock Consideration payable upon the
surrender of such Certificates.
 
  (c) If payment is to be made to a person other than the person in whose name
the Certificate surrendered in exchange therefor is registered, it shall be a
condition of payment of the Total Merger Consideration or Preference Stock
Consideration, as the case may be, that the Certificate so surrendered be
properly endorsed or accompanied by appropriate stock powers, in either case
signed exactly as the name of the record holder appears on such Certificate,
and is otherwise in proper form for transfer, and that the Person requesting
such payment shall pay any transfer or other taxes required by law as a result
of such payment to a Person other than the record holder of the Certificate
surrendered, or shall establish to Parent's satisfaction that such tax has
been paid or is not applicable.
 
  (d) After the Effective Date, there shall be no further transfers on the
stock transfer books of the Surviving Corporation of the shares of Company
Common Stock or Preference Stock which are outstanding at the Effective
 
                                       5

 
Date. If, after the Effective Date, Certificates are presented to the
Surviving Corporation or the Paying Agent for transfer, they shall be canceled
and there shall be issued to the transferee in exchange for each share of
Company Common Stock the Total Merger Consideration and in exchange for each
share of Preference Stock the Preference Stock Consideration in accordance
with Section 1.10 hereof.
 
  (e) The consideration payable upon the surrender for exchange of
Certificates in accordance with the terms of this Article I shall be deemed to
have been paid in full satisfaction of all rights pertaining to the shares of
Company Common Stock or Preference Stock theretofore represented by such
Certificates, and there shall be no further registration of transfers on the
stock transfer books of the Surviving Corporation of the shares of Company
Common Stock or Preference Stock which were outstanding immediately prior to
the Effective Date.
 
  (f) None of Parent, Acquisition Sub, the Company or the Paying Agent shall
be liable to any person in respect of any cash delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law. If any
Certificates shall not have been surrendered prior to seven years after the
Effective Date (or immediately prior to such earlier date on which any payment
pursuant to this Article I would otherwise escheat to or become the property
of any Governmental Authority), the payment in respect of such Certificate
shall, to the extent permitted by applicable law, become the property of any
Governmental Authority), the payment in respect of such Certificate shall, to
the extent permitted by applicable law, become the property of the Surviving
Corporation, free and clear of all claims or interest of any person previously
entitled thereto.
 
  Section 1.14. Certain Benefit Plans. (a)(i) With respect to unexpired
options ("Options"), whether or not exercisable at the Effective Date,
including stock appreciation rights relating thereto, outstanding on the
Effective Date which have been issued pursuant to the Company's 1982 Stock
Option Plan, as amended (the "1982 Stock Option Plan"), the Company's 1992
Stock Option Plan, as amended (the "1992 Stock Option Plan"), or the Company's
1992 Non-Employee Directors Stock Option Plan, as amended (the "Director
Option Plan"), each such Option with an exercise price less than the Total
Merger Consideration (an "Eligible Option") shall, by virtue of the Merger and
without any action on the part of the holder thereof, be converted into the
right to receive, for each share of Company Common Stock subject thereto, a
cash payment without interest equal to the Total Merger Consideration, less
the per share exercise price of each such Option. Such Options shall be
canceled upon such cash payment following the Merger.
 
    (ii) Any Option with an exercise price equal to or greater than the Total
  Merger Consideration (an "Ineligible Option") shall be canceled upon the
  Effective Date without payment of any consideration.
 
    (iii) The Company shall use its best efforts to amend each outstanding
  Option issued under the 1982 Stock Option Plan, the 1992 Stock Option Plan
  and the Director Option Plan to effect the transactions contemplated by
  this Agreement, including the cancellation of the Options in connection
  with the Merger in accordance with this Section 1.14.
 
  (b) There are no shares of Company Common Stock held in escrow pursuant to
the Company's former Long Term Incentive Compensation Plan (the "LTIP"), and
the LTIP has been terminated.
 
  (c) Each share of Company Common Stock issued by the Company but not yet
vested pursuant to the Company's Employees' Savings and Profit Sharing Plan
(the "Savings Plan") shall, in connection with the Merger, become vested in
the Person to whose account such share of Company Common Stock was issued and
converted into the right to receive the Total Merger Consideration as provided
in Section 1.10(a).
 
  (d) Immediately following the Effective Date, the Company's 1982 Stock
Option Plan, 1992 Stock Option Plan and Director Option Plan shall be
terminated and no further stock awards or stock options shall be granted
thereunder from and after the date of this Agreement.

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
  The Company hereby represents and warrants to Parent and Acquisition Sub as
follows with respect to the Company and its Subsidiaries:
 
  Section 2.01. Corporate Organization. The Company is a corporation duly
incorporated, validly existing and in good standing under the laws of the
Commonwealth of Massachusetts with all requisite corporate power and authority
to own, operate and lease its properties and to carry on its business as now
being conducted. The Company is qualified to do business and is in good
standing in each jurisdiction set forth in Schedule 2.01, which are the only
jurisdictions in which such qualification is necessary except where failure to
be qualified could not reasonably be expected to have a Material Adverse
Effect. For purposes of this Agreement, a "Material Adverse Effect" is (a) a
material adverse effect on the business, assets, properties, condition
(financial or other) or results of operations of the Company and its
Subsidiaries taken as a whole or the Surviving Corporation and its
Subsidiaries taken as a whole or (b) a material adverse effect on the ability
of the Company to carry out the transactions contemplated by this Agreement
without significant unanticipated delay or expense. For purposes of this
Agreement, a "Subsidiary" of any Person is any corporation of which a majority
of all outstanding shares of capital stock (the holders of which are
ordinarily and generally entitled to vote in the election of a majority of the
members of the board of directors thereof) is owned, directly or indirectly,
by such Person and/or other Subsidiaries of such Person. The Company has
delivered to Parent complete and correct copies of its Articles of
Organization and By-Laws, as amended to the date hereof.
 
  Section 2.02. Capitalization of the Company. (a) The authorized capital
stock of the Company consists of 15,000,000 shares of Company Common Stock,
15,000 shares of 5% Stock and 1,500,000 shares of Preference Stock. As of
December 31, 1997, 4,159,985 shares of Company Common Stock, 5,795 shares of
5% Stock and 814,300 shares of Preference Stock were issued and are
outstanding, and 275,112 shares of Company Common Stock were held in the
Company's treasury. All issued and outstanding shares of Company Common Stock,
5% Stock and Preference Stock are duly and validly issued and outstanding,
fully paid and nonassessable. As of the date hereof, the aggregate amount of
accrued and unpaid dividends on the 5% Stock is zero and on the Preference
Stock is $1,881,033.
 
  (b) As of the date hereof, there are outstanding unexercised, unexpired
Options to purchase 497,200 shares of Company Common Stock, in each case with
the exercise or "strike" price and other terms as set forth on Schedule 2.02
hereto.
 
  (c) Except as set forth in this Section 2.02 or on Schedule 2.02 hereto,
there are no other shares of capital stock of the Company, or securities
convertible into or exchangeable or exercisable for shares of capital stock of
the Company or any of its Subsidiaries, outstanding, and there are no
outstanding options, warrants, rights, contracts, commitments, understandings,
arrangements or claims of any character by which the Company or any Subsidiary
is or may become bound to issue, transfer, sell, repurchase or otherwise
acquire or retire any shares of capital stock or other ownership interest of
the Company or any Subsidiary, or any securities convertible into or
exchangeable or exercisable for any such shares or other ownership interest
(all of the foregoing being called "Conversion Rights") and, except as set
forth in Section 2.02(a) and as reserved for issuance upon exercise of the
Options described in Section 2.02(b) or the other Conversion Rights described
in Schedule 2.02, no shares of capital stock of the Company are reserved for
issuance. There are no voting trusts or other agreements or understandings to
which the Company is a party with respect to the voting of the capital stock
of the Company or any Subsidiary. Following consummation of the Merger no
holder or beneficiary of any Conversion Rights shall be entitled to receive
any securities of the Surviving Corporation or any other consideration not
expressly contemplated by this Agreement.
 
  Section 2.03. Subsidiaries. (a) Schedule 2.03 hereto sets forth each
Subsidiary and the jurisdiction of incorporation of such Subsidiary. Schedule
2.03 also sets forth each inactive Subsidiary (an "Inactive
 
                                       7

 
Subsidiary") of the Company. No Inactive Subsidiary has any assets or
liabilities valued in excess of $5,000 or any business operations or real
property nor has any Inactive Subsidiary conducted any business during the
two-year period prior to the date of this Agreement. Except as disclosed on
Schedule 2.03 hereto, all of the outstanding shares of capital stock and other
ownership interest of the Company's Subsidiaries are owned, directly or
indirectly, by the Company. Except as disclosed on Schedule 2.03, none of the
shares or other ownership interests of the Subsidiaries owned or held by the

  (b) Each Subsidiary (excluding each Inactive Subsidiary) is duly
incorporated, validly existing and in good standing under the laws of the
jurisdiction of incorporation of each such Subsidiary, with all requisite
corporate power and authority to own, operate and lease its properties and to
carry on its business as now being conducted. Each Subsidiary (excluding each
Inactive Subsidiary) is also qualified to do business and is in good standing
in each jurisdiction in which such qualification is necessary, except where
failure to be so qualified would not have a Material Adverse Effect. The
Company has delivered to Parent complete and correct copies of the respective
articles or certificates of incorporation or organization or By-Laws, as
amended to the date hereof, of each of its Subsidiaries.
 
  (c) Except for its Subsidiaries, the Company does not directly or indirectly
own any capital stock of or other equity interest in any corporation,
partnership or other person and neither the Company nor any of its
Subsidiaries is a member of or participant in any partnership, joint venture
or similar person.
 
  Section 2.04. Authorization. (a) The Company has requisite corporate power

Company, no other corporate proceeding on the part of the Company is necessary

contemplated hereby or to consummate the Offer, the Merger and the other
transactions contemplated hereby. The affirmative vote of the holders of (i)
two-thirds of the outstanding shares of Company Common Stock and (ii) two-
thirds of the outstanding shares of the Preference Stock, approving the Merger
are the only votes of the holders of any class or series of the Company's
capital stock necessary to approve any of the transactions contemplated by
this Agreement.
 
  (c) This Agreement has been duly and validly executed and delivered by the
Company and is a valid and binding agreement of the Company, enforceable
against the Company in accordance with its terms, and the Articles of Merger
when executed and delivered pursuant hereto will be a valid and binding
agreement of the Company enforceable against the Company in accordance with
its terms, except in each case as such enforceability may be limited by
bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or
similar laws in effect now or hereafter in effect relating to creditors'
rights generally, and by equitable principles (whether considered in a
proceeding at law or in equity).
 
  (d) The transfer of the Company's granule crushing equipment to the
Company's Wrentham and Franklin, MA quarry (at least with respect to the
"French parcel" of such quarry) and its operation at such location will not
conflict with, constitute a default under, result in the termination or in a
right of termination of, or violate or be in conflict with, provide a basis
for increased rights under, or result in a breach of any term or provision of,
any term or provision of any Material Contract.
 
  Section 2.05. Absence of Conflicts; Consents. Except as set forth in
Schedule 2.05, neither the execution and delivery by the Company of this
Agreement and the Articles of Merger nor the consummation by the Company of
the transactions contemplated hereby and thereby will:

  regulation, Permit, order or license (collectively, but excluding
  Environmental Laws, "Applicable Laws") of any governmental agency, body or

  Authority"), or any judicial, administrative or arbitration order, award,

  case applicable to the Company or any Subsidiary; or

  regulations thereunder (the "HSR Act").
 
  Section 2.06. Compliance with Laws. Neither the Company nor any Subsidiary
has been or is presently in violation of any provision of their respective
certificates or articles of organization or incorporation or By-Laws, or of
any Applicable Law or Judgment that would have a Material Adverse Effect.
Except where the failure thereof would not cause a Material Adverse Effect,
the Company and its Subsidiaries possess, and are in compliance in all
material respects with the terms and provisions of all licenses, permits,
certificates, authorizations, rights and other approvals of Governmental
Authorities ("Permits") necessary for the operation of the business of the
Company and its Subsidiaries. Except as set forth in Schedule 2.09 or 2.18,
neither the Company nor any Subsidiary has been given written notice by any
Governmental Authority of, or to the knowledge of Company, is under
investigation by any Governmental Authority with respect to, any violation of

environmental representations and warranties, which matters are exclusively
the subject of Section 2.18.

Forms 10-K and 10-Q filed with the SEC for the year ended December 31, 1996,
and the period ended September 30, 1997, respectively, including the
consolidated balance sheets of Company and its Subsidiaries as at December 31,
1995, December 31, 1996, and September 30, 1997, and the related consolidated

"Company
 
                                       9

 
Financial Statements"). The Company Financial Statements present fairly in all
material respects the consolidated financial position and the results of
operations of the Company and its Subsidiaries as of the dates and for the
periods indicated in the Company Financial Statements, in each case in
conformity with generally accepted accounting principles ("GAAP"),
consistently applied during such periods other than, in the case of the
statements as at and for the period ended September 30, 1997, for the absence
of required footnote disclosure and customary year-end adjustments. Except as
expressly contemplated or permitted by this Agreement or disclosed in the
Schedules hereto, to the knowledge of the Company, the Company and its
Subsidiaries do not have any material liabilities of any nature (whether
accrued, absolute, contingent, unasserted or otherwise) except (1) as
disclosed, reflected or reserved against in the balance sheet (the "Balance
Sheet") dated September 30, 1997 (the "Balance Sheet Date"), included in the
Company Financial Statements, and (2) as incurred in the ordinary course of
business consistent with past practice and not in violation of this Agreement.

the Balance Sheet or subsequently acquired, is, and will be as of the
Effective Date, generally of a quality and quantity usable and saleable,
consistent in all material respects with past practice, in the ordinary course
of business. The inventory of the Company and its Subsidiaries is reflected on
the Balance Sheet and in their respective accounting records in accordance
with GAAP applied on a basis consistent with past practice.
 
  (c) All accounts receivable of the Company and its Subsidiaries, whether
reflected on the Balance Sheet or subsequently created, have arisen from bona
fide transactions in the ordinary course of business. To the knowledge of the
Company, all accounts receivable reflected on the Balance Sheet are good and
collectible at the aggregate recorded amounts thereof, net of any applicable
reserves for doubtful accounts reflected on the Balance Sheet and all accounts
receivable created since the Balance Sheet Date are and will be as of the
Effective Date good and collectible at the aggregate recorded amounts thereof,
net of any applicable reserves for doubtful accounts reflected on the Balance
Sheet or subsequently created consistent with past practice and experience.
 
  Section 2.08. Absence of Material Changes. Except as set forth in Schedule
2.08 or as permitted by Section 5.06 or set forth in Schedule 5.06 or as
expressly contemplated or permitted by this Agreement, since the Balance Sheet
Date, each of the Company and its Subsidiaries has conducted its business in
the ordinary course, and there has not been (and it is not reasonably expected
there will be) (i) any event, change or circumstance causing, or reasonably
anticipated to cause in the future, any Material Adverse Effect, except as
otherwise disclosed to Parent in writing prior to the date of this Agreement,
(ii) any declaration, setting aside or payment of any dividend (whether in
cash, stock or property) with respect to any of the Company's capital stock,
other than the minimum required dividends declared on the 5% Stock or the
Preference Stock, (iii) (x) any granting by the Company or any of its
Subsidiaries to any executive officer or director of the Company or any of its
Subsidiaries of any increase in compensation, except as was required under
employment agreements in effect as of the Balance Sheet Date, (y) any granting
by the Company or any of its Subsidiaries to any such executive officer or
director of any increase in severance or termination pay, except as was
required under employment, severance or termination agreements in effect as of
the Balance Sheet Date or (z) any entry by the Company or any of its
Subsidiaries into any employment, severance or termination agreement with any
such executive officer or director, (iv) any damage, destruction or loss,
whether or not covered by insurance, that has or could have a Material Adverse
Effect, (v) any change in accounting methods, principles or practices by the
Company materially affecting its assets, liabilities or business, except
insofar as may have been required by a change in GAAP or (vi) any other action
that would be prohibited by Section 5.06 on and after the date of this
Agreement. As of the date hereof, the Company's reserves for potential
liabilities have not been materially reduced since the Balance Sheet Date and
the Company believes that such reserves are sufficient to cover the Company's
liabilities.
 
  Section 2.09. Litigation. Except as set forth in Schedule 2.09 and other
than routine warranty claims against the Company that do not in the aggregate
exceed in any material respect the level of such claims experienced
historically by the Company in the ordinary course, neither the Company nor
any Subsidiary is engaged in, and there is not to the knowledge of the Company
pending, nor has the Company or any Subsidiary received written notice of, any
legal action, suit, investigation, inquiry or proceeding by any Governmental
Authority or other Person ("Legal Action").
 
                                      10

 
  Section 2.10. Patents and Trademarks. To the knowledge of the Company, the
Company and its Subsidiaries own all patents, trademarks, service marks, trade
names, copyrights, trade secrets, information, proprietary rights and
processes necessary for their business as now conducted without any conflict
with or infringement of the rights of others. Except as set forth in Schedule
2.10, there are no outstanding options, licenses or agreements of any kind
relating to the foregoing, nor is the Company nor any Subsidiary bound by or a
party to any material options, licenses or agreements of any kind with respect
to the patents, trademarks, service marks, trade names, copyrights, trade
secrets, information, proprietary rights and processes of any other Person.
Except as set forth in Schedule 2.10 or relating to any matter that has been
resolved or that the Company reasonably believes has been abandoned, none of
the Company nor any Subsidiary has received any written communications
alleging that the Company or any Subsidiary has violated any of the patents,
trademarks, service marks, trade names, copyrights or trade secrets or other
proprietary rights of any other Person.
 
  Section 2.11. Material Contracts; Permits. Schedule 2.11(a) sets forth a
complete and accurate list of any of the following to which the Company or any
Subsidiary is a party or by which Company or any Subsidiary is bound
(collectively, "Material Contracts"):
 
    (a) all deeds, indentures, leases, subleases or other instruments by
  which an ownership, leasehold or other interest in real property is held by
  the Company or any Subsidiary;

director of the Company or any of its affiliates who is a "disqualified
individual" (as such term is defined in proposed Treasury Regulation Section

requested by such other party pertaining to it and its subsidiaries and
affiliates as may be required in order to enable such other party to take all
such actions as required by this Section 5.08. Nothing in this Agreement shall
require Parent to dispose of, or make any change
 
                                      26

 
in, any portion of its or the Company's assets or business or to pay any

  Section 5.11. Public Announcements. (a) The parties agree that the initial
press release to be issued with respect to the transactions contemplated by

Thereafter, unless required by Applicable Law or by the rules of any

Sub shall not, and shall each cause their respective officers, employees and
other authorized representatives not to, prior to the Effective Date, issue
any press release or make any other public disclosure or announcement or
otherwise make any disclosure to any third Person (other than by way of the

Section 5.02) concerning the transactions contemplated by this Agreement or
the terms and provisions hereof.
 
  (b) Should any press release or other public disclosure be required to be
made, then the party required to make such release or disclosure shall not
make such release or disclosure without first using its reasonable efforts to
obtain the prior written consent of the other parties hereto as to both the
timing and content of such press release or public disclosure, which consent
shall not be unreasonably withheld.
 
  Section 5.12. No Solicitation. (a) The Company shall not, nor shall it
permit any of its Subsidiaries or affiliates to, nor shall it authorize or
permit any officer, director or employee of, or any investment banker,
attorney or other advisor or representative of, the Company or any of its
Subsidiaries to, (i) solicit or initiate, or knowingly encourage the
submission of, any takeover proposal, (ii) participate in any discussions or
negotiations regarding, or furnish to any person any information with respect
to any takeover proposal (except for (1) non-confidential information, or (2)
filings with the SEC); provided, however, that prior to the earlier of (x) the
Consummation of the Offer or (y) the Special Meeting, to the extent required
by the fiduciary obligations of the Board of Directors of the Company, as
determined in good faith by the Board of Directors based on the advice of
counsel, the Company may, (A) in response to an unsolicited request therefor,
furnish information with respect to the Company (pursuant to a confidentiality
agreement at least as restrictive as the Confidentiality Agreement dated April
13, 1994, between the Company and Saint-Gobain Corporation, as amended (as
determined by the Company's counsel)) to any person who has indicated to the
Company that it is interested in pursuing a qualified takeover proposal and
discuss such information (but not the terms of any possible takeover proposal)
with such
 
                                      27

 
person and (B) upon receipt by the Company of a qualified takeover proposal,
following the delivery to Parent of the notice required pursuant to Section
5.12(c), participate in discussions or negotiations regarding such qualified
takeover proposal. Without limiting the foregoing, it is understood that any
violation of the restrictions set forth in the preceding sentence by any
officer of the Company or any of its Subsidiaries or any investment banker,
attorney or other advisor or representative of the Company or any of its
Subsidiaries, shall be deemed to be a breach of this Section 5.12 by the
Company. For purposes of this Agreement, "takeover proposal" means any
proposal for a merger or other business combination (regardless of legal form)
involving the Company or any Subsidiary or any proposal or offer to acquire in
any manner, directly or indirectly, a substantial portion of the assets or
business of the Company or a substantial equity interest in, or any
substantial amount of voting securities of, the Company or any Subsidiary, or
any other transaction outside the ordinary course of business and not
otherwise specifically permitted by the terms of this Agreement the
consummation of which would impede or prevent the consummation of the Merger
pursuant to the terms of this Agreement; and "qualified takeover proposal"
means a takeover proposal having terms which the Board of Directors of the
Company determines (based on, among other things, the advice of a financial
advisor of nationally recognized reputation and after giving due consideration
to the Stockholder Agreement dated the date hereof among Parent, Acquisition
Sub and the persons identified on Schedule A thereto) in its good faith
reasonable judgment to be more favorable to the holders of Company Common
Stock than the Total Merger Consideration and holders of Preference Stock than
the Preference Stock Consideration and likely to be fully financed and
consummated.
 
  (b) Neither the Board of Directors of the Company nor any committee thereof
shall (i) withdraw or modify, or propose to withdraw or modify, in a manner
adverse to Parent or Acquisition Sub, the approval or recommendation by such
Board of Directors or any such committee of this Agreement, the Offer or the
Merger, (ii) approve or recommend, or propose to approve or recommend, any
takeover proposal or (iii) enter into any agreement with respect to any
takeover proposal. Notwithstanding the foregoing, in the event the Board of
Directors of the Company receives a qualified takeover proposal, the Board of
Directors or any committee thereof or the Company may (subject to the
limitations contained in this Section) withdraw or modify its approval or
recommendation of this Agreement, the Offer or the Merger at any time after 48
hours following Parent's receipt of written notice (a "Notice of Qualified
Takeover Proposal") advising Parent that the Board of Directors has received a
qualified takeover proposal, specifying the material terms and conditions of
such qualified takeover proposal and identifying the person making such
qualified takeover proposal. The Company may take any of the foregoing actions
pursuant to the preceding sentence only until the earlier of (x) the
Consummation of the Offer or (y) the approval of the Merger at the Special
Meeting. Nothing contained herein shall prohibit the Company from taking and
disclosing to its stockholders a position contemplated by Rule 14e-2(a)
following Parent's receipt of a Notice of Qualified Takeover Proposal provided
that the Company does not withdraw or modify its position with respect to the
Merger or approve or recommend a takeover proposal.
 
  (c) In addition to the obligations of the Company set forth in paragraph (b)
of this Section, the Company shall promptly advise Parent orally and in
writing of any request for information or of any takeover proposal, or any
inquiry with respect to any takeover proposal, the material terms and
conditions of such request, takeover proposal or inquiry, and the identity of
the person making any such takeover proposal or inquiry. The Company shall
keep Parent fully informed of the status and details of any such request,
takeover proposal or inquiry.
 
  Section 5.13. Validity of Representations. Parent, Acquisition Sub and the
Company shall each take such action as is reasonably necessary to render their
respective representations and warranties accurate on and as of the Effective
Date. Without limiting the foregoing, the Company shall take any action
required by Parent to ensure the accuracy of Section 2.22 if Parent determines
that would be desirable.
 
  Section 5.14. Employees; Benefits. Parent and Acquisition Sub shall honor
(i) all employment, severance or similar contractual arrangements in
accordance with their terms in existence on the date of this Agreement and
disclosed prior to the date of this Agreement to Parent and (ii) all legally
imposed obligations relating to employment matters. After the Closing Date,
Parent and Acquisition Sub shall comply with enforceable Applicable Law,
including without limitation the Worker Adjustment and Retraining Notification
Act, 29 U.S.C. (S) 2101 et seq. It is the current intention of Parent and
Acquisition Sub to cause the Surviving
 
                                      28

 
Corporation to provide benefits to employees of the Company and its
Subsidiaries that are no less favorable in the aggregate to such employees
than those in effect on the date of this Agreement; provided, however, that
the foregoing shall not limit or restrict the right of the Surviving
Corporation or its Subsidiaries to terminate the employment of such employees
or subsequently to modify the benefits or other terms of employment of such
employees, to the extent permitted by enforceable Applicable Law.
 
  Section 5.15. Indemnification and Insurance. (a) Parent and Acquisition Sub
hereby agree that all rights to indemnification now existing in favor of the
directors or officers of the Company and its Subsidiaries (the "Indemnified
Parties") as currently provided in their respective certificates or articles
of incorporation or organization and By-Laws or in any agreements, contracts
or arrangements with the Company or any of its Subsidiaries in effect on the
date hereof and previously furnished to Parent and to the extent not in
violation of applicable state law, shall survive the Merger and shall continue
in full force and effect for a period of five years from the Effective Date;
provided that, in the event any claim or claims are asserted or made within
such five year period, all rights to indemnification in respect of any such
claim or claims shall continue until the disposition of any and all such
claims. Without limiting the foregoing, to the extent currently provided in
the certificates or articles of incorporation or organization and By-Laws of
the Company and its Subsidiaries and Massachusetts law, or agreements,
contracts or arrangements disclosed to Parent with the Company or any of the
Subsidiaries, in the event that any Indemnified Party becomes involved in any
capacity in any action, proceeding or investigation in connection with any
matter, including the transaction contemplated by this Agreement, occurring
prior to, and including, the Effective Date, or otherwise relating to or
arising out of such matters, Parent or the Surviving Corporation shall
periodically advance to such Indemnified Party his or her legal and other
expenses (including the costs of any investigation and preparation incurred in
connection therewith). Parent shall use all reasonable efforts to maintain in
effect, or shall cause the Surviving Corporation to use all reasonable efforts
to maintain in effect, for two years after the Effective Date, directors' and
officers' liability insurance ("D&O Insurance") covering those persons covered
by the Company's directors' and officers' liability insurance on the date of
this Agreement or the Effective Date and which is substantially equivalent in
terms of coverage and amount as the Company has in effect on the Effective
Date so long as such insurance is available and the annual premium therefor
would not be in excess of $166,000 (the "Maximum Premium"). If the existing
D&O Insurance expires, is terminated or cancelled during such two-year period,
Parent will use all reasonable efforts to cause to be obtained as much D&O
Insurance as can be obtained for the remainder of such period for an
annualized premium not in excess of the Maximum Premium, on terms and
conditions no less advantageous than the existing D&O Insurance.
 
  (b) Any Indemnified Party wishing to claim indemnification hereunder, upon
learning of any such Legal Action, shall promptly notify Parent and the
Surviving Corporation with respect thereto, but the failure to so notify shall
not relieve Parent or the Surviving Corporation of any liability it may have
to such Indemnified Party hereunder except to the extent that Parent and the
Surviving Corporation are materially prejudiced thereby.
 
  (c) Parent and the Surviving Corporation shall periodically, as requested,
advance to such Indemnified Party his, her or its legal and other expenses
(including the cost of investigation and preparation incurred in connection
therewith) to the extent such Indemnified Party is indemnified pursuant to the
terms of this Section 5.15, unless it is ultimately determined by a court of
competent jurisdiction that such Indemnified Party is not entitled to
indemnification hereunder.
 
  (d) Parent and the Surviving Corporation shall be subrogated to any rights
any Indemnified Party may have with respect to any amounts paid to or on
behalf of such Indemnified Party by Parent and the Surviving Corporation
hereunder.
 
  Section 5.16. Redemption of 5% Stock. (a) In connection with the Merger, the
Company, Parent and Acquisition Sub hereby agree that the 5% Stock shall be
redeemed and retired, as soon as practicable following the Effective Date for
the 5% Stock Consideration in accordance with the Surviving Corporation's
Articles of Organization.
 
 
                                      29

 
  (b) Prior to the date specified in the call notice for the redemption and
retirement of the 5% Stock, the Surviving Corporation shall cause to be
deposited with an appropriate trust company or bank, for the credit of the
holders of the 5% Stock, sufficient funds to be paid to such holders for
redemption and retirement of all of such shares of 5% Stock as provided for
herein and in the Surviving Corporation's Articles of Organization.
 
  Section 5.17. Material Contracts. The Company shall not enter into any
material modification or amendment concerning any Material Contract listed on
Schedule 2.11(a) or 2.11(b) without the consent of Parent, which consent shall
not be unreasonably withheld. Immediately after the Closing, Parent shall
cause the Surviving Corporation to pay the outstanding principal amount (and
accrued interest thereon) owed by the Company under each Material Contract set
forth on Schedule 2.11(b).
 
  Section 5.18. Tax Matters. Promptly after the request of Parent and in any
event no later than three months from the date of such request, the Company
shall provide to Parent true, complete and correct (in all material respects)
copies of (a) a schedule setting forth the deferred intercompany gain account,
and the excess loss account of each of its Subsidiaries, and (b) a schedule
setting forth the Federal income tax basis for the stock of each of the
Subsidiaries except those Subsidiaries for which such information cannot be
obtained after due inquiry.
 
  Section 5.19. Dividend Payments. The Company shall not declare or pay or set
apart for payment any accumulated dividends on the Preference Stock or 5%
Stock.
 
  Section 5.20. Satisfaction of Conditions. The Company, Parent and
Acquisition Sub shall each take all reasonable actions that may be required to
satisfy the conditions set forth in Article VI and Article VII hereof,
respectively.
 
  Section 5.21. Directors. Subject to compliance with applicable law
(including Section 14(f) of the Exchange Act), upon the acquisition by
Acquisition Sub of at least a majority of the outstanding Common Stock
pursuant to the Offer, Acquisition Sub shall be entitled to designate at least
a majority of the members of the Board of Directors of the Company, and the
Company and its Board of Directors shall, at such time, take any and all such
action (including to increase the size of the Board of Directors or to use its
best efforts to cause directors to resign) needed to cause a sufficient number
of Acquisition Sub's designees to be appointed to the Company's Board of
Directors that such designees shall constitute such majority (any director so
designated by Acquisition Sub, a "Designated Director"). It is understood that
immediately after the acquisition by Acquisition Sub of at least a majority of
the outstanding Common Stock pursuant to the Offer (x) the Company's Board of
Directors shall consist of seven members, (y) the initial designees of
Acquisition Sub to the Company's Board of Directors are expected to be George
B. Amoss, Gianpaolo Caccini, James E. Hilyard and Bradford C. Mattson and (z)
the remaining members of the Company's Board of Directors are expected to be
Antonio J. Lorusso, Jr., Richard C. Maloof and Frank Anthony. In the event
that, after the acquisition by Acquisition Sub of at least a majority of the
outstanding Common Stock pursuant to the Offer and prior to the Effective
Time, the number of members of the Board of Directors increases (including
pursuant to the provisions of the Preference Stock and the 5% Stock), the
Company and its Board of Directors shall, at such time, take any and all such
additional action (including to increase the size of the Board of Directors,
to use its best efforts to cause additional directors to resign and to appoint
additional designees of Acquisition Sub) needed to cause a sufficient number
of Acquisition Sub's designees to be appointed to the Board of Directors that
such designees shall then constitute at least a majority of the members of the
Board of Directors. The parties hereto shall use their respective best efforts
to cause at least three members of the Company's Board of Directors at all
times prior to the Effective Time to be Continuing Directors. "Continuing
Director" means (a) any member of the Company's Board of Directors on the date
of this Agreement, (b) any member of the Company's Board of Directors who is
not an employee or director or affiliate of, and not a Designated Director or
other nominee of, Acquisition Sub or Parent or their respective Subsidiaries,
and (c) any successor of a Continuing Director who is (i) not an employee or
director or affiliate of, and not a Designated Director or other nominee of,
Acquisition Sub or Parent or their respective Subsidiaries and (ii)
recommended to succeed such Continuing Director by at least a majority of the
then Continuing Directors.

                   MASSACHUSETTS GENERAL LAWS CHAPTER 156B,
                            SECTIONS 85 THROUGH 98:
                       RIGHTS OF DISSENTING STOCKHOLDERS
 
(S)85.  DISSENTING STOCKHOLDER; RIGHT TO DEMAND PAYMENT FOR STOCK; EXCEPTION
 
  A stockholder in any corporation organized under the laws of Massachusetts
which shall have duly voted to consolidate or merge with another corporation
or corporations under the provisions of sections seventy-eight or seventy-nine
who objects to such consolidation or merger may demand payment for his stock
from the resulting or surviving corporation and an appraisal in accordance
with the provisions of sections eighty-six to ninety-eight, inclusive, and
such stockholder and the resulting or surviving corporation shall have the
rights and duties and follow the procedure set forth in those sections. This
section shall not apply to the holders of any shares of stock of a constituent
corporation surviving a merger if, as permitted by subsection (c) of section
seventy-eight, the merger did not require for its approval a vote of the
stockholders of the surviving corporation.
 
(S)86.  SECTIONS APPLICABLE TO APPRAISAL; PREREQUISITES
 
  If a corporation proposes to take a corporate action as to which any section
of this chapter provides that a stockholder who objects to such action shall
have the right to demand payment for his shares and an appraisal thereof,
sections eighty-seven to ninety-eight, inclusive, shall apply except as
otherwise specifically provided in any section of this chapter. Except as
provided in sections eighty-two and eighty-three, no stockholder shall have
such right unless (1) he files with the corporation before the taking of the
vote of the shareholders on such corporate action, written objection to the
proposed action stating that he intends to demand payment for his shares if
the action is taken and (2) his shares are not voted in favor of the proposed
action.
 
(S)87.  STATEMENT OF RIGHTS OF OBJECTING STOCKHOLDERS IN NOTICE OF MEETING;
FORM
 
  The notice of the meeting of stockholders at which the approval of such
proposed action is to be considered shall contain a statement of the rights of
objecting stockholders. The giving of such notice shall not be deemed to
create any rights in any stockholder receiving the same to demand payment for
his stock, and the directors may authorize the inclusion in any such notice of
a statement of opinion by the management as to the existence or non-existence
of the right of the stockholders to demand payment for their stock on account
of the proposed corporate action. The notice may be in such form as the
directors or officers calling the meeting deem advisable, but the following
form of notice shall be sufficient to comply with this section:
 
  "If the action proposed is approved by the stockholders at the meeting and
effected by the corporation, any stockholder (1) who files with the
corporation before the taking of the vote on the approval of such action,
written objection to the proposed action stating that he intends to demand
payment for his shares if the action is taken and (2) whose shares are not
voted in favor of such action has or may have the right to demand in writing
from the corporation (or, in the case of a consolidation or merger, the name
of the resulting or surviving corporation shall be inserted), within twenty
days after the date of mailing to him of notice in writing that the corporate
action has become effective, payment for his shares and an appraisal of the
value thereof. Such corporation and any such stockholder shall in such cases
have the rights and duties and shall follow the procedure set forth in
sections 88 to 98, inclusive, of chapter 156B of the General Laws of
Massachusetts."
 
(S)88.  NOTICE OF EFFECTIVENESS OF ACTION OBJECTED TO
 
  The corporation taking such action, or in the case of a merger or
consolidation the surviving or resulting corporation, shall, within ten days
after the date on which such corporate action became effective, notify each
stockholder who filed a written objection meeting the requirements of section
eighty-six and whose shares were not voted in favor of the approval of such
action, that the action approved at the meeting of the corporation of
 
                                     AII-1

 
which he is a stockholder has become effective. The giving of such notice
shall not be deemed to create any rights in any stockholder receiving the same
to demand payment for his stock. The notice shall be sent by registered or
certified mail, addressed to the stockholder at his last known address as it
appears in the records of the corporation.
 
(S)89.  DEMAND FOR PAYMENT; TIME FOR PAYMENT
 
  If within twenty days after the date of mailing of a notice under subsection
(e) of section eighty-two, subsection (f) of section eighty-three, or section
eighty-eight, any stockholder to whom the corporation was required to give
such notice shall demand in writing from the corporation taking such action,
or in the case of a consolidation or merger from the resulting or surviving
corporation, payment for his stock, the corporation upon which such demand is
made shall pay to him the fair value of his stock within thirty days after the
expiration of the period during which such demand may be made.
 
(S)90.  DEMAND FOR DETERMINATION OF VALUE; BILL IN EQUITY; VENUE
 
  If during the period of thirty days provided for in section eighty-nine the
corporation upon which such demand is made and any such objecting stockholder
fail to agree as to the value of such stock, such corporation or any such
stockholder may within four months after the expiration of such thirty-day
period demand a determination of the value of the stock of all such objecting
stockholders by a bill in equity filed in the superior court in the county
where the corporation in which such objecting stockholder held stock had or
has its principal office in the commonwealth.
 
(S)91.  PARTIES TO SUIT TO DETERMINE VALUE; SERVICE
 
  If the bill is filed by the corporation, it shall name as parties respondent
all stockholders who have demanded payment for their shares and with whom the
corporation has not reached agreement as to the value thereof. If the bill is
filed by a stockholder, he shall bring the bill in his own behalf and in
behalf of all other stockholders who have demanded payment for their shares
and with whom the corporation has not reached agreement as to the value
thereof, and service of the bill shall be made upon the corporation by
subpoena with a copy of the bill annexed. The corporation shall file with its
answer a duly verified list of all such other stockholders, and such
stockholders shall thereupon be deemed to have been added as parties to the
bill. The corporation shall give notice in such form and returnable on such
date as the court shall order to each stockholder party to the bill by
registered or certified mail, addressed to the last known address of such
stockholder as shown in the records of the corporation, and the court may
order such additional notice by publication or otherwise as it deems
advisable. Each stockholder who makes demand as provided in section eighty-
nine shall be deemed to have consented to the provisions of this section
relating to notice, and the giving of notice by the corporation to any such
stockholder in compliance with the order of the court shall be a sufficient
service of process on him. Failure to give notice to any stockholder making
demand shall not invalidate the proceedings as to other stockholders to whom
notice was properly given, and the court may at any time before the entry of a
final decree make supplementary orders of notice.
 
(S)92.  DECREE DETERMINING VALUE AND ORDERING PAYMENT; VALUATION DATE
 
  After hearing the court shall enter a decree determining the fair value of
the stock of those stockholders who have become entitled to the valuation of
and payment for their shares, and shall order the corporation to make payment
of such value, together with interest, if any, as hereinafter provided, to the
stockholders entitled thereto upon the transfer by them to the corporation of
the certificates representing such stock if certificated or, if
uncertificated, upon receipt of an instruction transferring such stock to the
corporation. For this purpose, the value of the shares shall be determined as
of the day preceding the date of the vote approving the proposed corporate
action and shall be exclusive of any element of value arising from the
expectation or accomplishment of the proposed corporate action.
 
                                     AII-2

 
(S)93.  REFERENCE TO SPECIAL MASTER
 
  The court in its discretion may refer the bill or any question arising
thereunder to a special master to hear the parties, make findings and report
the same to the court, all in accordance with the usual practice in suits in
equity in the superior court.
 
(S)94.  NOTATION ON STOCK CERTIFICATES OF PENDENCY OF BILL
 
  On motion the court may order stockholder parties to the bill to submit
their certificates of stock to the corporation for notation thereon of the
pendency of the bill, and may on motion dismiss the bill as to any stockholder
who fails to comply with such order.
 
(S)95.  COSTS; INTEREST
 
  The costs of the bill, including the reasonable compensation and expenses of
any master appointed by the court, but exclusive of fees of counsel or of
experts retained by any party, shall be determined by the court and taxed upon
the parties to the bill, or any of them, in such manner as appears to be
equitable, except that all costs of giving notice to stockholders as provided
in this chapter shall be paid by the corporation. Interest shall be paid upon
any award from the date of the vote approving the proposed corporate action,
and the court may on application of any interested party determine the amount
of interest to be paid in the case of any stockholder.
 
(S)96.  DIVIDENDS AND VOTING RIGHTS AFTER DEMAND FOR PAYMENT
 
  Any stockholder who has demanded payment for his stock as provided in this
chapter shall not thereafter be entitled to notice of any meeting of
stockholders or to vote such stock for any purpose and shall not be entitled
to the payment of dividends or other distribution on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the date of the vote approving the proposed corporate
action) unless:
 
    (1) A bill shall not be filed within the time provided in section ninety;
 
    (2) A bill, if filed, shall be dismissed as to such stockholder; or
 
    (3) Such stockholder shall with the written approval of the corporation,
  or in the case of a consolidation or merger, the resulting or surviving
  corporation, deliver to it a written withdrawal of his objections to and an
  acceptance of such corporate action.
 
  Notwithstanding the provisions of clauses (1) to (3), inclusive, said
stockholder shall have only the rights of a stockholder who did not so demand
payment for his stock as provided in this chapter.
 
(S)97.  STATUS OF SHARES PAID FOR
 
  The shares of the corporation paid for by the corporation pursuant to the
provisions of this chapter shall have the status of treasury stock, or in the
case of a consolidation or merger the shares or the securities of the
resulting or surviving corporation into which the shares of such objecting
stockholder would have been converted had he not objected to such
consolidation or merger shall have the status of treasury stock or securities.
 
(S)98.  EXCLUSIVE REMEDY; EXCEPTION
 
  The enforcement by a stockholder of his right to receive payment for his
shares in the manner provided in this chapter shall be an exclusive remedy
except that this chapter shall not exclude the right of such stockholder to
bring or maintain an appropriate proceeding to obtain relief on the ground
that such corporate action will be or is illegal or fraudulent as to him.

                                LEHMAN BROTHERS
 
                                                               January 12, 1998
 
Bird Corporation
1077 Pleasant Street
Norwood, MA 02062
 
Members of the Board:
 
  We understand that Bird Corporation ("Bird" or the "Company") proposes to
enter into a merger agreement with CertainTeed Corporation ("CertainTeed")
pursuant to which CertainTeed will acquire all of the capital stock of the
Company for aggregate consideration of $39.8 million in cash and assumption of
the Company's outstanding indebtedness, which as of September 30, 1997, was
approximately $3.5 million (the "Proposed Transaction"). The terms and
conditions of the Proposed Transaction are set forth in more detail in the
draft merger agreement dated January 9, 1998 among Bird, CertainTeed and BI
Expansion II Corp. (the "Agreement").
 
  We have been requested by the Board of Directors of the Company to render
our opinion with respect to the fairness, from a financial point of view, to
the Company's stockholders of the consideration to be paid by CertainTeed in
the Proposed Transaction. Our opinion does not in any manner address: (i) the
Company's underlying business decision to proceed with or effect the Proposed
Transaction or (ii) consideration to be received by any class of stockholders
of the Company.
 
  In arriving at our opinion, we reviewed and analyzed: (1) the Agreement and
the specific terms of the Proposed Transaction, (2) publicly available
information concerning the Company that we believe to be relevant to our
analysis, (3) financial and operating information with respect to the
business, operations and prospects of the Company furnished to us by the
Company (including without limitation the Company's recent financial results
in comparison to original budget), (4) a trading history of the Company's
capital stock from January 1995 to the present and a comparison of that
trading history with those of other companies that we deemed relevant, (5) a
comparison of the historical financial results and present financial condition
of the Company with those of other companies that we deemed relevant, and (6)
a comparison of the financial terms of the Proposed Transaction with the
financial terms of certain other transactions that we deemed relevant. In
addition, we have had discussions with management of the Company concerning
indications of interest received from, and discussions with, potential
strategic buyers of the Company with respect to an acquisition of the Company.
We also have had discussions with the management of the Company concerning its
business, operations, assets, financial condition and prospects and the
current competitive environment in its industry, and have undertaken such
other studies, analyses and investigations as we deemed appropriate.
 
  In arriving at our opinion, we have assumed and relied upon the accuracy and
completeness of the financial and other information used by us without
assuming any responsibility for independent verification of such information
and have further relied upon the assurances of management of the Company that
they are not aware of any facts or circumstances that would make such
information inaccurate or misleading. With respect to the financial
projections of the Company, upon advice of the Company we have assumed that
such projections have been reasonably prepared on a basis reflecting the best
currently available estimates and judgments of the management of the Company
as to the future financial performance of the Company and we have relied upon
such projections in arriving at our opinion. In arriving at our opinion, we
have conducted only a limited physical inspection of the properties and
facilities of the Company and have not made or obtained any evaluations or
appraisals of the assets or liabilities of the Company. In addition, you have
not authorized us to solicit, and we

 
have not solicited, any proposals from any third party with respect to the
purchase of all or a part of the Company's business. Our opinion necessarily
is based upon market, economic and other conditions as they exist on, and can
be evaluated as of, the date of this letter.
 
  Based upon and subject to the foregoing, we are of the opinion as of the
date hereof that, from a financial point of view, the consideration to be paid
by CertainTeed in the Proposed Transaction is fair to the stockholders of the
Company.
 
  We have acted as financial advisor to the Company in connection with the
Proposed Transaction and will receive a fee for the delivery of this opinion.
In addition, the Company has agreed to indemnify us for certain liabilities
that may arise out of the rendering of this opinion.
 
  This opinion is for the use and benefit of the Board of Directors of the
Company and is rendered to the Board of Directors in connection with its
consideration of the Proposed Transaction. This opinion is not intended to be
and does not constitute a recommendation to any stockholder of the Company as
to whether to accept the consideration to be offered to such stockholder in
connection with the Proposed Transaction.
 
                                          Very truly yours,
 
                                          LEHMAN BROTHERS
 
                                    AIII- 2
